An observational and retrospective study was carried out to analyse HCoV positivity from a multiplex PCR respiratory panel and RT-PCR for SARS-CoV-2 in respiratory samples from 1 June 2020 to 31 July 2023 at the Príncipe de Asturias University Hospital (HUPA) in Alcalá de Henares, Madrid, Spain. Out of 2802 respiratory panels, 1258 (44.8%) turned out positive. HCoV was detected in 114 (4%) cases (range 0-23; median 1.5; IQR 0-3.75) with positivity rates ranging from 0% to 14%. All four variants of HCoV circulated, and OC-43 was the most common in 62.3% of cases. After the onset of the pandemic, the HCoV season was delayed 22 weeks, with a peak positivity of 9% in the summer of 2021, showing an inverse relationship with the alpha and delta waves of SARS-CoV-2. In the two subsequent autumn-winter seasons, HCoV positivity increased (11-14%) with a reduction in the summer of 2022 and 2023 following the emergence of the omicron variant and the relaxation of social distancing measures. The seasonal spread pattern of endemic HCoV might be returning to normal in our region and likely in other temperate zones of the northern hemisphere after 3 years of the pandemic., (© 2024 The Author(s).

Chlamydia psittaci pneumonia (CPP) exhibits similar characteristics as of COVID-19 with respect to clustering outbreaks and onset symptoms. This study is aimed at exploring the different clinical manifestations of both pneumonias to establish a simple nomogram to distinguish them. This multicenter, retrospective, case-control study compared two independent cohorts of patients with CPP or COVID-19. The risk factors of CPP were analyzed using multivariate logistic regression, which was used to establish the nomogram. Both patients with CPP and COVID-19 exhibited similar clinical symptoms. As compared to patients with COVID-19, a higher proportion of patients with CPP had nervous system symptoms. Patients with CPP had higher inflammatory indicators, creatine kinase, and lower lymphocyte and albumin. They also had lower proportions of ground-glass opacity and bilateral lung involvement than COVID-19 patients. Furthermore, patients with CPP had higher 30 day mortality as well as higher rates of severe pneumonia, septic shock, and ICU admission. Multivariate logistic regression showed that nervous system symptoms, lymphocytes, creatine kinase, bilateral lung lesions, and ground-glass opacity were risk factors for CPP. Incorporating these five factors, the nomogram achieved good concordance index of 0.989 in differentiating CPP from COVID-19, and had well-fitted calibration curves. Despite similar clinical characteristics, nervous system symptoms, lymphocyte, creatine kinase, lesions in bilateral lungs, and ground-glass opacity may help in differentiating the pneumonias. These were combined into a clinically useful nomogram for rapid and early identification of CPP to avoid misdiagnosis and help in the decision-making process., (© 2024. The Author(s).)

Background: Trazodone, an antidepressant drug is also largely used in several medical contexts. Insomnia, behavioral disorders, and anxiety may be underlying symptoms for prescribing trazodone. This cross-sectional study aims to identify reasons for trazodone prescription, assess the efficacy, as well as identify any related side effects in older persons living in long term care facilities (LTCFs)., Methods: Older adults aged ≥ 60 years, at risk of or affected with Covid-19 and enrolled in the GeroCovid Observational study from LTCFs, and using trazodone were included. A structured questionnaire was administered to treating physicians regarding reasons for trazodone prescription, discontinuation, possible adverse events and benefits., Results: Thirty-seven out 74 LTCFs participating in both the GeroCovid and GeroCovid Vax studies completed the questionnaire regarding trazodone use. Of the 427 participants included in this study analysis, we found that 43% had diagnoses of dementia and depression, 33% had dementia, no behavioral and psychological symptoms of dementia (BPSD) and no depression, 14% had dementia with BPSD and no depression, and < 11% had only depression. The main reasons for trazodone prescription included agitation, insomnia, depression and anxiety. Trazodone use was reported as partially or totally effective in more than 90% of participants using the drug. Falls were the most frequent adverse event (30% of participants)., Conclusions: Our data suggest that trazodone behaves as an eclectic antidepressant that, in the clinical practice, may also be used for BPSD and insomnia, especially in older people with dementia., (© 2024 John Wiley & Sons Ltd.)

Background: Early identification of risk factors for adverse COVID-19 progression in patients with autoimmune diseases is crucial for patient management, but data on the Chinese population are scarce., Objectives: The purpose of this study was to identify predictors of severe COVID-19 in patients using blood cell ratios, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and other inflammatory markers., Methods: A retrospective study of 855 patients (746 females; median age 49 years) with autoimmune diseases and concurrent COVID-19 was conducted from December 2022 to February 2023 at the Rheumatology and Immunology Department of the First Affiliated Hospital of Nanchang University. Disease severity was assessed according to the 8th edition of the National Health Commission of the People's Republic of China's COVID-19 Diagnosis and Treatment Guidelines. The clinical classification criteria group mild and moderate cases as nonsevere cases and severe and critical cases as severe cases. A multivariate logistic regression model was established to evaluate the relationships between COVID-19 severity and demographic characteristics, comorbidities, medication use, and laboratory findings., Results: The PLR, NLR, and SII were significantly greater in the severe COVID-19 group than in the nonsevere group (all P < 0.05). In addition to classical independent clinical risk factors, increases in the PLR (OR: 1.004, 95 % CI: 1.001∼1.007, p = 0.001), NLR (OR: 1.180, 95 % CI: 1.041∼1.337, p = 0.010), and SII (OR: 0.999, 95 % CI: 0.998∼1.000, p = 0.005) were identified as risk factors for severe COVID-19 in patients with autoimmune diseases. After adjusting for clinical risk factors, the PLR (AUC: 0.592 vs. 0.865; P < 0.05), NLR (AUC: 0.670 vs. 0.866; P < 0.05), and SII (AUC: 0.616 vs. 0.864; P < 0.05) demonstrated higher predictive values., Conclusion: Early prediction of severe COVID-19 in patients with autoimmune diseases can be achieved using the NLR, PLR, and SII., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Corticosteroids have always been recommended for severe cases of COVID-19. However, the efficacy of treatment with corticosteroids for COVID-19 during the SARS-CoV-2 omicron outbreak in China has not been reported. Clinical data from 406 patients hospitalized for severe/critical COVID-19 from December 2022 to January 2023 at six hospitals in Chongqing were retrospectively analyzed. The primary outcome was all-cause mortality at 28 days in the groups with and without corticosteroids treatment after propensity score matching (PSM). Secondary outcomes were to compare in-hospital mortality and length of survival time with corticosteroids and those without corticosteroids. This study included 406 patients with severe or critical COVID-19, divided into the corticosteroids group (231, 56.9%) and non-corticosteroids group (175, 43.1%). After PSM, the use of corticosteroids did not reduce all-cause mortality at 28 days (42.5% vs. 39.1%). Univariate analysis showed that corticosteroids were not associated with improved all-cause mortality at 28 days [hazard ratio (HR), 1.019; 95% confidence interval (CI), 0.639-1.623; p = 0.938]. Multivariate analysis showed similar results (HR, 1.047; 95% CI, 0.633-1.732; p = 0.858). Among non-survivors, the survival time was significantly larger in those who received corticosteroids compared with the non-corticosteroid users [median 13 (IQR 6.5-15.5) vs. 6 (4-11.25), p = 0.007]. The use of systemic corticosteroids in severe/critical COVID-19 may provide certain potential survival benefits but does not improve prognosis., (© 2024. The Author(s).)

Objective: To assess the changes in maternal-fetal outcomes in a nonepidemic designated hospital during the COVID-19 pandemic., Methods: This retrospective cohort study was conducted between January 1, 2019, and December 31, 2021 on pregnant patients. The fixed-effects regression model was used to determine changes in birth outcomes and pregnancy-related complications between three periods with the pre-epidemic cohort as the control group. Logistic regression was applied to determine the odds ratio (OR) for binary outcomes., Results: There were 15,261 births during the pre-epidemic period, and this number decreased by 15% and 23% to 12,980 and 11,736 in the first and second epidemic cohorts, respectively. The mean birth weight during the pre-epidemic period was 3319 which decreased to 3309 and 3272 g in the following periods. Excluding stillbirth and preterm, all other outcomes differed significantly between the three periods. Gestational diabetes mellitus (GDM) (17-19%) and maternal hypertension (9.2-11%) appeared to increase. Compared to the pre-epidemic period, the odds of macrosomia and LGA significantly decreased in the second epidemic cohort (adjusted ORs: 0.76 and 0.8), while the odds of low birth weight (LBW) and small gestation age (SGA) increased (ORs: 1.25 and 1.16). The odds of neonatal asphyxia (OR: 1.4), and hypertension (OR: 1.29) appeared to increase in the second epidemic cohort, while GDM decreased in the first cohort (OR: 0.88) and increased in the second cohort (OR: 1.15). Vaginal delivery underwent a marginal decrease in both the first and second epidemic cohorts (ORs: 0.89 and 0.92)., Conclusion: The COVID-19 pandemic may have had a substantial and long-term impact on non-infected pregnant women and newborns. Our research results provided precious research information and clinical experience summary for population health research in the future., (© 2024. The Author(s).)

Background and Objectives: Elevated levels of pro-inflammatory cytokines have been linked to increased mortality in COVID-19 patients. Infliximab, a tumor necrosis factor inhibitor, has been reported to improve outcomes in COVID-19 patients by targeting the hyperinflammatory response. Our objective was to evaluate the effectiveness of incorporating Infliximab into standard care guidelines for the management of COVID-19. Materials and Methods : A retrospective analysis was conducted on 111 participants who were moderate to severe COVID-19 patients admitted to the hospital. Among them, 74 individuals received solely standard treatment, while 37 received standard therapy plus Infliximab. The primary outcomes of the study centered around the changes in laboratory test parameters. The secondary clinical findings included clinical recovery defined as improvement in patient oxygenation, time till recovery, and assessing necessity for ICU admission, and mortality rates. Results: There was no statistical difference observed in the inflammatory markers including, LDH, Ferritin, CRP, neutrophil to lymphocyte ratio (NLR), and P/F ratio between both groups and in the clinical outcomes including clinical recovery ( p = 1.0), time to improvement ( p = 0.436), and mortality rate ( p = 0.601). However, there was a significant increase in secondary infection (45.9%, 20.3%; p = 0.005), and in liver enzymes, ALT (79.5, 50.0 IU/L; p = 0.02) and AST (57.5, 38.0 IU/L; p = 0.019) in the Infliximab group and the standard care group, respectively. Conclusions: Infliximab therapy did not demonstrate significant benefits compared to standard of care in moderate to severe hospitalized COVID-19 patients.

Objectives: With the emergence of new COVID-19 variants (Omicron BA.5.2.48 and B.7.14), predicting the mortality of infected patients has become increasingly challenging due to the continuous mutation of the virus. Existing models have shown poor performance and limited clinical utility. This study aims to identify the independent risk factors and develop practical predictive models for mortality among patients infected with new COVID-19 variants., Design: A retrospective study., Setting and Participants: We extracted data from 1029 COVID-19 patients in the respiratory disease wards of a general hospital in China between 22 December 2022 and 15 February 2023., Outcome Measures: Mortality within 15 days after hospital discharge., Results: A total of 987 cases with new COVID-19 variants (Omicron BA.5.2.48 and B.7.14) were eventually included, among them, 153 (15.5%) died. Non-invasive ventilation, intubation, myoglobin, international normalised ratio, age, number of diagnoses, respiratory rate, pulse, neutrophil count and albumin were the most important predictors of mortality among new COVID-19 variants. The area under the curve of logistic regression (LR), decision tree (DT) and Extreme Gradient Boosting (XGBoost) models were 0.959, 0.883 and 0.993, respectively. The diagnostic accuracy was 0.926 for LR, 0.918 for DT and 0.977 for XGBoost. XGBoost model had the highest sensitivity (0.908) and specificity (0.989)., Conclusion: Our study developed and validated three practical models for predicting mortality in patients with new COVID-19 variants. All models performed well, and XGBoost was the best-performing model., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Over the past decade, numerous studies on potential factors contributing to ventilation-induced lung injury have been carried out. Mechanical power has been pointed out as the parameter that encloses all ventilation-induced lung injury-contributing factors. However, studies conducted to date provide data regarding mechanical power during the early hours of mechanical ventilation that may not accurately reflect the impact of power throughout the period of mechanical ventilatory support on intensive care unit mortality., Methods: Retrospective observational study conducted at a single center in Spain. Patients admitted to the intensive care unit, > o = 18 years of age, and ventilated for over 24 h were included. We extracted the mechanical power values throughout the entire mechanical ventilation in controlled modes period from the clinical information system every 2 min. First, we calculate the cutoff-point for mechanical power beyond which there was a greater change in the probability of death. After, the sum of time values above the safe cut-off point was calculated to obtain the value in hours. We analyzed if the number of hours the patient was under ventilation with a mechanical power above the safe threshold was associated with intensive care unit mortality, invasive mechanical ventilation days, and intensive care unit length of stay. We repeated the analysis in different subgroups based on the degree of hypoxemia and in patients with SARS CoV-2 pneumonia., Results: The cut-off point of mechanical power at with there is a higher increase in intensive care unit mortality was 18 J/min. The greater the number of hours patients were under mechanical power > 18 J/min the higher the intensive care unit mortality in all the study population, in patients with SARS CoV-2 pneumonia and in mild to moderate hypoxemic respiratory failure. The risk of death in the intensive care unit increases 0.1% for each hour with mechanical power exceeding 18 J/min. The number of hours with mechanical power > 18 J/min also affected the days of invasive mechanical ventilation and intensive care unit length of stay., Conclusions: The number of hours with mechanical power > 18 J/min is associated with mortality in the intensive care unit in critically ill patients. Continuous monitoring of mechanical power in controlled modes using an automated clinical information system could alert the clinician to this risk., (© 2024. The Author(s).)

Background: The COVID-19 pandemic accelerated telehealth adoption across disease cohorts of patients. For many patients, routine medical care was no longer an option, and others chose not to visit medical offices in order to minimize COVID-19 exposure. In this study, we take a comprehensive multidisease approach in studying the impact of the COVID-19 pandemic on health care usage and the adoption of telemedicine through the first 12 months of the COVID-19 pandemic., Objective: We studied the impact of the COVID-19 pandemic on in-person health care usage and telehealth adoption across chronic diseases to understand differences in telehealth adoption across disease cohorts and patient demographics (such as the Social Vulnerability Index [SVI])., Methods: We conducted a retrospective cohort study of 6 different disease cohorts (anxiety: n=67,578; depression: n=45,570; diabetes: n=81,885; kidney failure: n=29,284; heart failure: n=21,152; and cancer: n=35,460). We used summary statistics to characterize changes in usage and regression analysis to study how patient characteristics relate to in-person health care and telehealth adoption and usage during the first 12 months of the pandemic., Results: We observed a reduction in in-person health care usage across disease cohorts (ranging from 10% to 24%). For most diseases we study, telehealth appointments offset the reduction in in-person visits. Furthermore, for anxiety and depression, the increase in telehealth usage exceeds the reduction in in-person visits (by up to 5%). We observed that younger patients and men have higher telehealth usage after accounting for other covariates. Patients from higher SVI areas are less likely to use telehealth; however, if they do, they have a higher number of telehealth visits, after accounting for other covariates., Conclusions: The COVID-19 pandemic affected health care usage across diseases, and the role of telehealth in replacing in-person visits varies by disease cohort. Understanding these differences can inform current practices and provides opportunities to further guide modalities of in-person and telehealth visits. Critically, further study is needed to understand barriers to telehealth service usage for patients in higher SVI areas. A better understanding of the role of social determinants of health may lead to more support for patients and help individual health care providers improve access to care for patients with chronic conditions., (©Margrét Vilborg Bjarnadóttir, David Anderson, Kelley M Anderson, Omar Aljwfi, Alina Peluso, Adam Ghannoum, Gayle Balba, Nawar Shara.

Background: Neurological complications have been observed in approximately 30% of hospitalized COVID-19 patients. The aim of this study was to evaluate whether early assessment of the Neurological Pupil Index (NPi TM ) derived from an automated pupillometry could predict mortality in critically ill COVID-19 patients., Methods: Retrospective cohort study of adult critically ill COVID-19 patients admitted to the intensive care unit of a University Hospital; patients without NPi measurement were excluded. The worst NPi (i.e. lowest value from one eye) was collected daily and then computed over the first five days of assessment. Mortality was assessed at hospital discharge. The secondary endpoint involved assessing differences in neurological assessments between patients who developed neurological complications and those who did not., Results: A total of 217 patients were included over the study period (median age 61 [50-68] years), 70% were males. A total of 97 patients (45%) died during the hospital stay. Among all patients, 35 (16%) experienced neurological complications. Non-survivors showed significantly a lower overall NPi (3.0 [2.0-4.1] vs. 3.4 [2.7-4.2]; P=0.04) than survivors. At multivariate logistic regression NPi was not significantly associated with in-hospital mortality. Moreover, no differences in different NPi measurements were observed between patients with and without neurological complications., Conclusions: In this study, NPi values were not independent predictor of mortality and neurological complications in critically ill COVID-19 patients.

In late 2019, a novel coronavirus emerged in Wuhan, China, causing an atypical pneumonia- like illness. Scientists subsequently isolated the virus, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), in January 2020. This highly contagious virus rapidly spread worldwide, triggering a global public health emergency. The ongoing Covid-19 pandemic necessitates continuous evaluation of the characteristics of infected individuals. This study aimed to investigate the demographic and clinical features of patients diagnosed with Covid-19 at a tertiary care hospital in Bangladesh. This retrospective cross-sectional study was conducted between November 2023 and February 2024 at the Department of Respiratory Medicine, Uttara Adhunik Medical College Hospital (UAMCH), Dhaka, Bangladesh. The study involved collaboration with the departments of Virology and the hospital's Covid Unit. Data were collected from the medical records of 200 confirmed Covid-19-positive cases admitted upon arrival at the hospital. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 23.0. Of the 200 participants, the most frequent age group was 46-60 years old, representing 42% (84 patients). Males comprised the majority (73.0%, 145 patients), and most participants resided in urban areas of Bangladesh (86.5%, 173 patients). The socioeconomic analysis revealed that the upper-class category had the highest frequency (85.0%, 170 patients). Diabetes Mellitus (DM) emerged as the most prevalent co-morbidity (58.5%, 117 patients). Regarding clinical presentation, fever was the most frequent symptom (76.0%, 152 patients), followed by cough (47.5%, 95 patients), shortness of breath (SOB) (27.5%, 55 patients), and pneumonia (15.0%, 30 patients). Less frequent symptoms included acute respiratory distress syndrome (ARDS), lower respiratory tract infection (LRTI), and chest pain. The mean systolic and diastolic blood pressure readings were 126.61±14.58 mmHg and 77.24±12.44 mmHg respectively. The mean oxygen saturation (SaO2) was 93.39±5.53%. This study investigated that the most frequent age group was (46-60) years. The male dominant in Covid-19-positive cases. Diabetes Mellitus (DM) was observed as the most frequent co-morbidity. The common symptoms of Covid-19-positive cases were fever, cough, SOB, pneumonia acute respiratory distress syndrome, lower respiratory tract infection, chest pain, high blood pressure and low oxygen saturation.

Background: There is insufficient data on orofacial pain related to the COVID-19 outbreak in Thailand., Objective: To investigate the incidence, diagnosis and management of orofacial pain among new patients over the last 6 years, before and during the COVID-19 outbreak., Methods: Medical records from new patients who first visited Chulalongkorn Dental Hospital between 2017 and 2022 were retrospectively investigated. The sample size was determined, and proportional stratified random sampling was employed to distribute the sample number proportionally across each year. The hospital number of each patient was randomised using online software as a sampling strategy. A data collection form was developed and used to gather information from the digital data system., Results: At the first visit, 770 out of 1359 patients (56.7/100 people, 95% CI: 54.0-59.3) reported orofacial pain defined as acute, chronic and unclassified pain. The most common chief complaints based on the AAOP classification were odontogenic pain (90.00%) and temporomandibular disorders (6.10%). The top three provisional modified ICD-10-TM diagnoses among these patients were pulp diseases (21.95%), impacted teeth (20.65%) and dental caries (9.09%). 81.87% of dental students' provisional diagnoses matched the final diagnoses given by dental specialists. Only 63.38% of orofacial pain patients were completely managed during the COVID-19 pandemic with common procedures being surgical removal, extraction and root canal therapy., Conclusion: Half of Thai dental patients seeking tertiary care at a university dental hospital reported orofacial pain, which was not impacted by the COVID-19 pandemic. In contrast, dysfunction-related problems in the orofacial area significantly increased during the pandemic., (© 2024 John Wiley & Sons Ltd.)

Objective: The Medicare Benefit Schedule (MBS) telehealth items were expanded in March 2020 during the COVID-19 pandemic. We measured the use of MBS telepsychiatry items compared to consultant physician telehealth items within the context of these item changes, to understand differences in telepsychiatry and physician telehealth utilisation., Methods: Monthly counts of face-to-face and telehealth (videoconferencing and telephone) MBS items for psychiatrists and physicians from January 2017 to December 2022 were compiled from Services Australia MBS Item Reports. Usage levels were compared before and after telehealth item expansion. Usage trends for MBS telepsychiatry and physician telehealth items were compared in time-series plots., Results: Telehealth item expansion resulted in a greater rise of telepsychiatry services from 3.8% beforehand to 43.8% of total services subsequently, compared with physician telehealth services (from 0.6% to 20.0%). More physician telehealth services were by telephone compared with telepsychiatry services. Time-series of both telehealth services displayed similar patterns until mid-2022, when physician telehealth services declined as telephone items were restricted. Telepsychiatry services consistently comprised a greater proportion of total services than physician telehealth services., Conclusions: MBS psychiatrist services showed a more substantial and persistent shift to telehealth than physician services, suggesting a greater preference and use of telepsychiatry., Competing Interests: DisclosureThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: The objective of this study is to evaluate the epidemiological characteristics of Japanese Spotted Fever (JSF) cases reported through the National Epidemiological Surveillance of Infectious Disease (NESID) system in Shimane Prefecture, Japan, from 2000 to 2022, encompassing the periods before and during the COVID-19 pandemic period., Methods: A retrospective analysis was conducted on JSF cases reported to the NESID system in Shimane Prefecture between 2000 and 2022. Population data were obtained from the Statistical Information of Shimane. Poisson regression analysis was employed to examine the relationship between the annual prevalence rate of JSF and the COVID-19 pandemic., Results: A total of 301 JSF cases were analyzed during the study period. Even the pre-COVID-19 pandemic period, a gradual and significant increase in the prevalence rate was observed (prevalence rate = 1.03, 95% CI: 1.01-1.05; p = 0.01), and a rapid increase was noted since 2020 (prevalence rate = 1.57, 95% CI: 1.39-1.78; p < 0.01). The slope during the pre-COVID-19 pandemic period was estimated to have significantly increased (p < 0.01)., Conclusions: Our findings suggest that while the prevalence rate of JSF had exhibited a slight increase in the years preceding the COVID-19 pandemic, it demonstrated a more significant increase following the pandemic in Shimane Prefecture. JSF has increased since 2020 and may be linked to COVID-19 pandemic. The COVID-19 pandemic has had a substantial impact on global health, underscoring the importance of investigating the prevalence of specific infectious diseases and other health-related indicators to accurately assess the pandemic's impact., Competing Interests: Declaration of competing interest The authors have that no conflict of interest to declare., (Copyright © 2024 Japanese Society of Chemotherapy, Japanese Association for Infectious Diseases, and Japanese Society for Infection Prevention and Control.

Background: Analyzing antidepressant prescribing in real-world settings can provide clinicians and health policymakers valuable information., Aim: This epidemiological study examined the status and trends in antidepressant prescribing among the Chinese population from July 1, 2017, to June 30, 2022., Method: A retrospective study was conducted in three hospitals. Data were collected 2.5 years before and 2.5 years after the onset of the COVID-19 pandemic. We analyzed the number of patients diagnosed with depression and their corresponding antidepressant prescriptions. Using the chi-square test, stratified analyses were performed to explore the characteristics of these prescriptions in different ages and sexes., Results: The study included 124,355 patients and 400,840 antidepressant prescriptions. We observed fluctuating upward trends in the number of patients and antidepressant prescriptions. Post-COVID-19, the number of patients increased by 37.1% compared to the pre-pandemic period, and the number of antidepressant prescriptions rose by 88.3%. The three most frequently prescribed antidepressants for adolescents were sertraline, citalopram, and escitalopram. Among adults, citalopram, escitalopram, and sertraline were most common, while in older adults, citalopram, escitalopram, and mirtazapine were predominant. Male patients used mirtazapine, venlafaxine, paroxetine, bupropion, fluvoxamine, vortioxetine, and clomipramine more frequently compared to female patients, who were more likely to be prescribed citalopram, flupentixol/melitracen, agomelatine, and fluoxetine. Antidepressant monotherapy represented 76.6% of prescriptions, with the most common combination being antidepressants and anxiolytics., Conclusion: Over the past 5 years, both the number of patients and antidepressant prescriptions have shown upward trends, and the COVID-19 pandemic has impacted prescribing. Understanding the changes in antidepressant prescriptions can identify adherence to national guidelines., (© 2024. The Author(s), under exclusive licence to Springer Nature Switzerland AG.)

Introduction: The purpose of this research was to investigate the outcomes of coronavirus disease 2019 (COVID-19) infection in healthcare workers, assess the incidence of infection among them, and identify factors linked to the severity of the disease., Methodology: This cross-sectional study was conducted retrospectively in Duhok city, Kurdistan Region of Iraq, from September 2021 to January 2023., Results: The study included 1,958 participants, of whom 1,338 (68.33%) contracted the infection. Among them, 830 (62.03%) and 372 (27.81%) patients experienced mild and moderate infections, respectively, while 136 (10.1%) had severe infections. The results indicated that several factors, including maintaining a healthy lifestyle, avoiding obesity, having a chronic condition, working consecutive hours, and being in an overwhelmed work environment were significantly associated with a higher severity of infection (p < 0.05). However, factors such as smoking habits, adherence to preventive health guidelines, direct exposure to COVID-19 patients, work days and patterns, family members with COVID-19, and hand/glove sterilization did not appear to have a significant effect on the severity of infection (p > 0.05)., Conclusions: These findings may offer valuable insights for clinicians and public health officials, and aid in the development of effective strategies to manage COVID-19 patients based on their risk factors for infection severity., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2024 Nawfal R Hussein, Ronahi Y Ibrahim, Shameran S Daniel, Majeed H Mustafa, Salar N Jakhsi, Shilan MT Husamaldeen, Khalid H Haleem, Ibrahim A Naqid, Zana SM Saleem, Ahmed S Mahdi, Nashwan MR Ibrahim, Ameen M Mohammad, Avan S Saleh, Rasheed M Ameen, Dildar H Musa, Rojan S Saleh, Selah S Haji.)

Introduction: The study aimed to compare the outcomes of nirmatrelvir and ritonavir drug combination (Paxlovid) therapy in patients who received treatment within or after five days of COVID-19 confirmed in the elderly., Methodology: This was a single-center, retrospective cohort study of older COVID-19 patients (≥ 60 years) admitted from April 7 to May 30, 2022. Patients were categorized into the EP group (starting Paxlovid within five days) and the LP group (starting Paxlovid after five days) following symptoms onset. Length of stay and positive SARS-CoV-2 duration were compared between the two groups. Severe case conversion from mild and moderate COVID-19 patients were also analyzed., Results: In total, 273 patients were included: 137 in the EP group and 136 in the LP group. Compared to the LP group, the EP group had a significantly shorter length of stay (12.4 vs. 14.7 days, p = 0.001) and positive SARS-CoV-2 duration (11.7 vs. 15.8 days, p < 0.001). The EP group had lower severe case conversion (4.4% vs. 15.4%, p = 0.002). Additionally, abnormal IL-6 and lower lymphocyte count indicated increased length of stay. Older age was associated with a decreased risk in SARS-CoV-2 negative test (HR = 0.98) and an increased risk in severe case conversion (OR = 1.11)., Conclusions: Starting Paxlovid within five days of COVID-19 symptoms onset reduced the length of stay and SARS-CoV-2 duration compared to initiating treatment after five days. While severe case conversion among mild COVID-19 patients might be comparable whether starting Paxlovid within or after five days., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2024 Junjun Chen, Quanjun Yang, Xiaohong Xu, Xia Wu, Yonglong Han, Cheng Guo, Jiao Yang.)

Purpose: Convalescent plasma (CP) collected from people who recovered from COVID-19 became a rapidly available treatment modality in numerous countries, including the Czech Republic. The aims of our study were to evaluate the effectiveness and safety of CP in the treatment of COVID-19., Methods: This retrospective observational study involved six Czech hospitals. This study enrolled patients with and without CP treatment who were hospitalized between April 2020 and April 2021. Propensity score matching and logistic regression analysis were performed to evaluate the influence of CP administration and its timing on the in-hospital survival of COVID-19 patients., Results: A total of 1,498 patients were enrolled in the study; 406 (27%) were administered CP, and 1,092 (73%) were not treated with CP. The propensity score-matched control group consisted of 1,218 subjects. The survival of patients treated with CP was 79%, while that of patients in the matched control group was 62% (P<0.001). Moreover, the chance of survival was significantly greater when CP was administered within three days after the onset of COVID-19 symptoms than when CP was administered after four or more days (87% vs. 76%, P <0.001). In addition, adverse effects related to CP administration were recorded in only 2% of patients and were considered mild in all patients., Conclusions: Our study demonstrated that the administration of CP was safe and possibly associated with positive effects that were more pronounced if CP was administered within the first three days after the onset of COVID-19 symptoms., (© 2024.

Background: Pakistan reported 1.57 million COVID-19 cases between 2020 and 2022, based on approximately 30.6 million SARS-CoV-2 RT-PCR (reverse-transcription polymerase chain reaction) tests conducted. This study utilized data from one of the largest in-country testing facilities, Aga Khan University Hospital (AKUH) in Karachi, Pakistan, to explore gender and age-related in RT-PCR testing patterns., Methods: We conducted a retrospective review of SARS-CoV-2 RT-PCR test data extracted from AKUH clinical laboratory records between February 2020 and February 2022. Gender and age distributions were examined in the context of testing patterns across the period. Multivariate regression models assessed independent associations between COVID-19 positivity and key variables., Results: We reviewed 470,249 RT-PCR tests, finding that most tests were in those aged 21-40 years (48.1%). Overall, COVID-19 test positivity was 20.6%. In all, 57.7% were performed for males, predominant amongst those tested across all age groups and waves. Females had significantly lower odds of testing positive for COVID-19 (OR: 0.9; 95% CI: 0.9-1.0). However, when adjusted for gender, age and pandemic phases, the positivity rates between males and females were the same. The odds of a positive result increased significantly with age; individuals aged > 80 years had 2.5 times higher odds of testing positive than those aged 0-10 years (aOR 2.5, 95% CI 2.3-2.7)., Conclusions: The analysis indicates a consistent male dominance in COVID-19 testing, with higher positivity rates in older age groups. Our study highlight the importance of examining demographic characteristics in disease associated data especially, representation of females amongst cohorts., (© 2024. The Author(s).)

Background: Respiratory syncytial virus (RSV), a leading cause of lower respiratory tract infection (LRTI) among children, has resurged in the form of endemic or even pandemic in many countries and areas after the easing of COVID-19 containment measures. This study aimed to investigate the differences in epidemiological and clinical characteristics of children hospitalized for RSV infection during pre- and post-COVID-19 eras in Yunnan, China., Methods: A total of 2553 pediatric RSV inpatients from eight hospitals in Yunnan were retrospectively enrolled in this study, including 1451 patients admitted in 2018-2019 (pre-COVID-19 group) and 1102 patients admitted in 2023 (post-COVID-19 group). According to the presence or absence of severe LRTI (SLRTI), patients in the pre- and post-COVID-19 groups were further divided into the respective severe or non-severe subgroups, thus analyzing the risk factors for RSV-associated SLRTI in the two eras. Demographic, epidemiological, clinical, and laboratory data of the patients were collected for the final analysis., Results: A shift in the seasonal pattern of RSV activity was observed between the pre-and post-COVID-19 groups. The peak period of RSV hospitalizations in the pre-COVID-19 group was during January-April and October-December in both 2018 and 2019, whereas that in the post-COVID-19 group was from April to September in 2023. Older age, more frequent clinical manifestations (fever, acute otitis media, seizures), and elevated laboratory indicators [neutrophil-to-lymphocyte ratio (NLR), c-reactive protein (CRP), interleukin 6 (IL-6), co-infection rate] were identified in the post-COVID-19 group than those in the pre-COVID-19 group (all P < 0.05). Furthermore, compared to the pre-COVID-19 group, the post-COVID-19 group displayed higher rates of SLRTI and mechanical ventilation, with a longer length of hospital stay (all P < 0.05). Age, low birthweight, preterm birth, personal history of atopy, underlying condition, NLR, IL-6 were the shared independent risk factors for RSV-related SLRTI in both pre- and post-COVID-19 groups, whereas seizures and co-infection were independently associated with SLRTI only in the post-COVID-19 group., Conclusions: An off-season RSV endemic was observed in Yunnan during the post-COVID-19 era, with changed clinical features and increased severity. Age, low birthweight, preterm birth, personal history of atopy, underlying condition, NLR, IL-6, seizures, and co-infection were the risk factors for RSV-related SLRTI in the post-COVID-19 era., (© 2024.

Background: The epidemiology of fungi identified via next-generation sequencing in bronchoalveolar lavage fluid among patients with COVID-19 is unknown., Methods: De-identified information, including age, SARS-CoV-2 reads and fungi from bronchoalveolar lavage fluid, were used to analysis., Results: A total of 960 patients with COVID-19 were included. Gender was unknown in 38 patients, and 648 (70.3%) of the rest patients were male. For 876 patients with information on age, their mean ± standard age was 63.4 ± 21.3 years, with the minimum being 0.2 years and the maximum being 101 years. For all the patients, their median [interquartile range] SARS-CoV-2 reads were 26,038 [4421.5, 44,641.5]. The Aspergilli were identified in 159 (16.6%) patients, with Aspergillus fumigatus, Aspergillus flavus and Aspergillus niger in 103 (10.7%), 81 (8.4%) and 17 (1.8%), respectively. The Mucoraceae were identified in 14 (1.5%) patients. Pneumocystis jirovecii was identified in 65 (6.8%) patients, among whom 12 (18.5%) patients also had Aspergilli. The Cryptococcaceae and the Dematiaceae were also identified in some patients, including Cryptococcus in 11 (1.1%) patients., Conclusions: In bronchoalveolar lavage fluid among patients with COVID-19, the Aspergilli were very commonly identified, as were the Mucoraceae, Pneumocystis jirovecii and Cryptococcus via next-generation sequencing., (© 2024.

Background: Reports on coronavirus disease 2019 (COVID-19) in neonates are limited, especially in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) Omicron variant. This study aims to analyze the clinical characteristics and identify risk factors associated with severe COVID-19 in neonates infected with Omicron variant., Methods: The study population was represented by neonates with COVID-19, who were admitted to The Affiliated Children's Hospital of Xi'an Jiaotong University in northwest China, from December 10, 2022 to January 20, 2023. Chinese Center for Disease Control and Prevention (CDC) announced that all local COVID-19 cases were infected with Omicron variant during the study period. Clinical and laboratory data were collected retrospectively. We used logistic regression analysis to investigate the risk factors for severe COVID-19, and derived odds ratios (ORs) and the corresponding 95% confidence intervals (CIs)., Results: A total of 108 neonates, with median age of 18.1 days (interquartile range 9.4-23.0), were affected by COVID-19, of whom 84 had a mild disease, while 24 a severe one (22.2%). Of them, 6.5% were premature. No deaths were observed in the study population. The most common clinical manifestations were fever (88.9%) and cough (55.6%), with 5 cases (4.6%) complicated by pneumonia. 4 cases (3.7%) received respiratory support, including 2 cases of high-flow oxygen and 2 cases of continuous positive airway pressure. Gestational age at birth (OR: 0.615; 95% CI: 0.393-0.961), neutrophil count (NEU) (OR:0.576; 95% CI : 0.344-0.962) and lymphocyte count (LYM) (OR: 0.159; 95% CI: 0.063-0.401) were independent risk factors for severe COVID-19. The combination of NEU and LYM had the largest receiver operating characteristic area under the curve [0.912 (95% CI:0.830-0.993)] for identifying severe COVID-19, with a sensitivity of 0.833 and a specificity of 0.917., Conclusions: The general presentations and outcomes of neonatal COVID-19 caused by Omicron variant were not severe, and very few patients required respiratory support. The simultaneous decrease in NEU and LYM can be used to identify severe infection., (© 2024. The Author(s).)

Background: Group B Streptococcus (GBS) is a major cause of sepsis and meningitis in newborns. The Centers for Disease Control and Prevention (CDC) recommends to pregnant women, between 35 and 37 weeks of gestation, universal vaginal-rectal screening for GBS colonization, aimed at intrapartum antibiotic prophylaxis (IAP). The latter is the only currently available and highly effective method against early onset GBS neonatal infections. Since the onset of the coronavirus disease 2019 (COVID-19) pandemic, the preventive measures implemented to mitigate the effects of SARS-CoV-2 infection led to the reduction in the access to many health facilities and services, including the obstetric and perinatal ones. The purpose of the present study was to evaluate the prevalence of maternal GBS colonization, as well as use of IAP and incidence of episodes of neonatal GBS infection when antibiotic prophylaxis has not been carried out in colonized and/or at risk subjects, in a population of pregnant women during (years 2020-2021) and after (year 2022) the COVID-19 pandemic, also with the aim to establish possible epidemiological and clinical differences in the two subjects' groups., Methods: We retrospectively analyzed the clinical data of pregnant women admitted to, and delivering, at the Gynaecology and Obstetrics Unit, Department of Sciences for Health Promotion and Mother and Child Care, of the University Hospital of Palermo, Italy, from 01.01.2020 to 31.12.2022. For each of them, we recorded pertinent socio-demographic information, clinical data related to pregnancy, delivery and peripartum, and specifically execution and status of vaginal and rectal swab test for GBS detection, along with eventual administration and modality of IAP. The neonatal outcome was investigated in all cases at risk (positive maternal swabs status for GBS, either vaginal or rectal, with or without/incomplete IAP, preterm labor and/or delivery, premature rupture of membranes ≥ 18 h, previous pregnancy ended with neonatal early onset GBS disease [EOD], urine culture positive for GBS in any trimester of current gestation, intrapartum temperature ≥ 38 °C and/or any clinical/laboratory signs of suspected chorioamnionitis). The data concerning mothers and neonates at risk, observed during the pandemic (years 2020-2021), were compared with those of both subjects' groups with overlapping risk factors recorded in the following period (year 2022). The chi squared test has been applied in order to find out the relationship between pregnant women with GBS colonization receiving IAP and outcome of their neonates., Results: The total source population of the study consisted of 2109 pregnant women, in addition to their 2144 newborns. Our analysis, however, focused on women and neonates with risk factors. The vaginal-rectal swab for GBS was performed in 1559 (73.92%) individuals. The test resulted positive in 178 cases overall (11.42% of those undergoing the screening). Amongst our whole sample of 2109 subjects, 298 women had an indication for IAP (vaginal and/or rectal GBS colonization, previous pregnancy ended with neonatal GBS EOD, urine culture positive for GBS in any trimester of current gestation, and unknown GBS status at labor onset with at least any among delivery at < 37 weeks' gestation, amniotic membranes rupture ≥ 18 h and/or intrapartum temperature ≥ 38.0 °C), and 64 (21.48%) received adequate treatment; for 23 (7.72%) it was inadequate/incomplete, while 211 (70.8%) did not receive IAP despite maternal GBS colonization and/or the presence of any of the above mentioned risk factors. Comparing the frequency of performing vaginal-rectal swabs in the women admitted in the two time periods, the quote of those screened out of the total in the pandemic period (years 2020-2021) was higher than that of those undergoing GBS screening out of the total admitted in the year 2022 (75.65% vs. 70.38%, p = 0.009), while a greater number (not statistically significant, p = 0.12) of adequate and complete IAP was conducted in 2022, than in the previous biennium (26.36 vs. 18.62%). During the whole 3 years study period, as expected, none of the newborns of mothers with GBS colonization and/or risk factors receiving IAP developed EOD. Conversely, 13 neonates with EOD, out of 179 (7.3%) born to mothers with risk factors, were observed: 3 among these patients' mothers performed incomplete IAP, while the other 10 did not receive IAP. Neither cases of neonatal meningitis, nor deaths were observed. The incidence rate in the full triennium under investigation, estimated as the ratio between the number of babies developing the disease out of the total of 2144 newborns, was 6.06‰; among those born to mothers with risk factors, if comparing the two time periods, the incidence was 8.06% in the pandemic biennium, while 5.45% in the following year, evidencing thus no statistical significance (p = 0.53)., Conclusions: The present study revealed in our Department an increased prevalence of pregnant women screened for, and colonized by GBS, in the last decade. However, an overall still low frequency of vaginal-rectal swabs performed for GBS, and low number of adequate and complete IAP despite the presence of risk factors have been found, which did not notably change during the two time periods. Moreover, significant EOD incidence rates have been reported among children of mothers carrying risk factors, although also in this case no statistically significant differences have been observed during and after the pandemic. Such data seem to be in contrast to those reported during the COVID-19, showing a decrease in the access to health facilities and increased mortality/morbidity rates also due to the restrictive measures adopted to mitigate the effects of the pandemic. These findings might be explained by the presence within the same metropolitan area of our Department of a COVID hospital and birthing center, which all the patients with SARS-CoV-2 infection referred to, and likely leading to a weaker concern of getting sick perceived by our patients. Although IAP is an easy procedure to implement, however adherence and uniformity in the management protocols are still not optimal. Therefore, the prophylactic measures adopted to date cannot be considered fully satisfactory, and should be improved. Better skills integration and obstetrical-neonatological collaboration, in addition to new effective preventive tools, like vaccines able to prevent invasive disease, may allow further reduction in morbidity and mortality rates related to GBS perinatal infection., (© 2024.

Background: The COVID-19 pandemic resulted in a massive disruption in access to care and thus passive, hospital- and clinic-based surveillance programs. In 2020, the reported cases of Lyme disease were the lowest both across the United States and North Carolina in recent years. During this period, human contact patterns began to shift with higher rates of greenspace utilization and outdoor activities, putting more people into contact with potential vectors and associated vector-borne diseases. Lyme disease reporting relies on passive surveillance systems, which were likely disrupted by changes in health care-seeking behavior during the pandemic., Objective: This study aimed to quantify the likely under-ascertainment of cases of Lyme disease during the COVID-19 pandemic in the United States and North Carolina., Methods: We fitted publicly available, reported Lyme disease cases for both the United States and North Carolina prior to the year 2020 to predict the number of anticipated Lyme disease cases in the absence of the pandemic using a Bayesian modeling approach. We then compared the ratio of reported cases divided by the predicted cases to quantify the number of likely under-ascertained cases. We then fitted geospatial models to further quantify the spatial distribution of the likely under-ascertained cases and characterize spatial dynamics at local scales., Results: Reported cases of Lyme Disease were lower in 2020 in both the United States and North Carolina than prior years. Our findings suggest that roughly 14,200 cases may have gone undetected given historical trends prior to the pandemic. Furthermore, we estimate that only 40% to 80% of Lyme diseases cases were detected in North Carolina between August 2020 and February 2021, the peak months of the COVID-19 pandemic in both the United States and North Carolina, with prior ascertainment rates returning to normal levels after this period. Our models suggest both strong temporal effects with higher numbers of cases reported in the summer months as well as strong geographic effects., Conclusions: Ascertainment rates of Lyme disease were highly variable during the pandemic period both at national and subnational scales. Our findings suggest that there may have been a substantial number of unreported Lyme disease cases despite an apparent increase in greenspace utilization. The use of counterfactual modeling using spatial and historical trends can provide insight into the likely numbers of missed cases. Variable ascertainment of cases has implications for passive surveillance programs, especially in the trending of disease morbidity and outbreak detection, suggesting that other methods may be appropriate for outbreak detection during disturbances to these passive surveillance systems., (© Brie S Jones, Michael E DeWitt, Jennifer J Wenner, John W Sanders.

Although COVID-19 infection is an immunosuppressant disease, many immunosuppressant agents, such as pulse methylprednisolone (PMP), dexamethasone (DXM), and tocilizumab (TCZ), were used during the pandemic. Secondary infections in patients with COVID-19 have been reported recently. This study investigated these agents' effects on secondary infections and outcomes in patients with COVID-19 in intensive care units (ICUs). This study was designed retrospectively, and all data were collected from the tertiary intensive care units of six hospitals between March 2020 and October 2021. All patients were divided into three groups: Group I [GI, PMP (-), DXM (-) and TCZ (-)], Group II [GII, PMP (+), DXM (+)], and Group III [GIII, PMP (+), DXM (+), TCZ (+)]. Demographic data, P a O/FiO 2 ratio, laboratory parameters, culture results, and outcomes were recorded. To compare GI-GII and GI-GIII, propensity score matching (PSM) was used by matching 14 parameters. Four hundred twelve patients with COVID-19 in the ICU were included in the study. The number of patients with microorganisms ≥ 2 was 279 (67.7%). After PSM, in GII and GIII, the number of (+) tracheal cultures and (+) bloodstream cultures detected different microorganisms ≥ 2 during the ICU period, neuropathy, tracheotomized patients, duration of IMV, and length of ICU stay were significantly higher than GI. The mortality rate was similar in GI and GII, whereas it was significantly higher in GIII than in GI. The use of immunosuppressant agents in COVID-19 patients may lead to an increase in secondary infections. In addition, increased secondary infections may lead to prolonged ICU stay, prolonged IMV duration, and increased mortality., (© 2024. The Author(s).)

Objectives: We aim to investigate the prevalence of respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) among pediatric patients with acute respiratory tract illness (ARTI) in southern China both pre- and post-COVID-19 pandemic, as well as identify associated risk factors for severe infections., Methods: The study conducted a real-time PCR analysis on hospitalized children with ARTI from 2012 to 2023, specifically targeting RSV, hMPV, and other respiratory pathogens. Additionally, demographic data was collected during this analysis., Results: The prevalence of RSV occurs triennially, and likewise, the temporal pattern of hMPV outbreaks mirrors that of RSV. The peak infection rates of RSV and hMPV occurred during and following the implementation of COVID-19 epidemic prevention and control measures. The incidence of RSV infection exhibited bimodal peaks in 2022, while hMPV demonstrated seasonal peaks during the spring, fall, and winter periods post-COVID-19 pandemic. After the COVID-19 outbreak, there has been an upward trend in the proportion of female patients and patients aged one year and older presenting with ARTI, RSV infections, and hMPV infections. Infant (OR = 4.767, 95%CI: [3.888-5.846], p < 0.0001), presence of co-infection (OR = 0.540, 95%CI: [0.404-0.722], p < 0.0001), and existence of comorbidities (OR = 1.582, 95%CI: [1.285-1.949], p < 0.0001) was the risk ratio for the severity of RSV infection. Children infected with hMPV under the age of 1 year (OR = 0.322, 95%CI: [0.180 - 0.575], p < 0.0001), as well as those with comorbidities (OR = 8.809, 95%CI: [4.493 - 17.272], p < 0.0001), have a higher risk of developing severe illness., Conclusion: The changing epidemiological patterns have the potential to lead to widespread severe outbreaks among children, particularly those with underlying medical conditions who may experience more severe symptoms. Conducting surveillance for pneumoviridae viruses in children is an imperative measure to establish a robust foundation for future epidemic prevention and treatment strategies., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Kuang, Xu, Wang, Xie, Zhang, Guo, Liang and Zhu.)

Introduction Falls are the second leading cause of accidental or unintentional death worldwide. In hospital falls represent a relevant health problem, in particular after their increasing since Covid year 2020. The aim of this study is to evaluate correlation between falls and Covid infection., Methods: Risk Management Unit at Mauriziano hospital analyzed in the present observational study possible correlation with Covid Pandemic and falls risk factors, through comparison of patients falls occurred during year 2021 in Covid and no-Covid wards. The primary outcome of the study is the evaluation of relationship between falls and Covid infection. The secondary outcome is identification of falls risk factors., Results: No direct correlation between falls and Covid-19 infection was found. Among falls risk factors, the most interesting emerged is the fall itself that enhances the risk of relapse., Discussion: Increasing in patients falls since 2020 could be affected indirectly by strong hospital organization modifications during Covid pandemic.

Background: Treatment delay in head and neck cancer is a major problem, with impact on survival. The COVID-19 (coronavirus disease 2019) pandemic, evolving in waves around the world, caused diagnostic and therapeutic delays in certain cancers. The main objective of the present study was to analyze whether there was a change in wait times during three successive waves in our center., Method: This was a single-center retrospective study of patients with a first diagnosis of head and neck cancer. Three groups, corresponding to waves 2, 3 and 4, were compared to a control group corresponding to a pre-pandemic period. Study data comprised median times between first consultation and tumor board meeting (C1-TB) and between tumor board meeting and treatment (TB-T). The significance threshold was set at P<0.005., Results: Ninety-six patients were included in the control group, and 154 in the "waves 2-3-4" group. There was no increase in C1-TB interval (respectively 35 and 26days, P=0.046) or TB-T interval (respectively 27 and 28days, P=0.723)., Conclusion: Intervals between first consultation and tumor board meeting and between tumor board meeting and treatment did not increase during the 2nd, 3rd and 4th waves of COVID-19 in our center., (Copyright © 2024 Elsevier Masson SAS.

Objective: This study aimed to analyse the bacterial composition, distribution, drug sensitivity, and clinical characteristics of patients with coronavirus disease 2019 (COVID-19) who develop bacterial co-infections., Methods: We conducted a retrospective study of 184 patients with COVID-19 admitted between December 2022 and January 2023. Data on gender, age, length of hospital stay, pneumonia classification, underlying diseases, invasive surgery, hormone therapy, inflammation indicators, and other relevant information were collected. Samples of sputum, bronchoscopy sputum, alveolar lavage fluid, middle urine, puncture fluid, wound secretions, and blood were collected for pathogen isolation, identification, and drug sensitivity testing., Results: The majority of patients with COVID-19 with bacterial co-infection were elderly and had underlying diseases. Invasive surgery and hormone therapy were identified as risk factors for co-infections. Laboratory analysis showed reduced lymphocyte counts and elevated levels of C-reactive protein and procalcitonin. The most common pathogens in co-infections were Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa. The detection rate of drug-resistant strains, including methicillin-resistant S. aureus, carbapenem-resistant K. pneumoniae, carbapenem-resistant A. baumannii, carbapenem-resistant P. aeruginosa, and carbapenem-resistant E. coli, increased with the severity of pneumonia., Conclusion: Respiratory tract infections were the most common site of bacterial co-infection in patients with COVID-19. Severe cases were more susceptible to multidrug-resistant pathogens, leading to a higher mortality rate. Timely control and prevention of co-infection are crucial for improving the prognosis of patients with COVID-19., Competing Interests: Competing interest The authors declare no conflicts of interest., (Copyright © 2024 The Author(s).

The risk that COVID-19 poses for mortality risk in individuals with schizophrenia in low- and middle-income countries has only been the subject of a few studies. In this retrospective study, we examined the standardized mortality ratio (SMR), by age group and sex, in a cohort of patients diagnosed with schizophrenia (n = 20,417), with second-generation antipsychotics, in a South Brazilian State database (Paraná-Brazil). We performed a linkage with the Brazilian Mortality Information System database between 2020 and 2021. We also assessed in a logistic regression how clozapine could affect COVID-19 mortality controlling by sex, age, and presence of obesity. A secondary analysis was to compare mortality with SMR due to COVID-19 in individuals with and without obesity. Compared to the State population (8,850,682 individuals), those with schizophrenia had more than two times greater risk of dying from COVID-19 (SMR = 2.21, 95 % CI: 1.90-2.55). Between the ages of 16 and 29, their risk is more than ten times higher than the state population (SMR = 10.18, 95 % CI: 4.73-19.33). Obesity showed an almost twofold risk of dying from COVID-19 in the patient's group (OR = 1.89, 95 % CI: 1.39-2.57). Clozapine was not found as a protector or a risk factor for COVID-19 mortality. In Brazil, a middle-income nation, people with schizophrenia are more likely to die prematurely from COVID-19. The burden of schizophrenia is higher in younger and in patients with obesity., Competing Interests: Declaration of competing interest AG has been a consultant/advisor and/or has received honoraria from Aché, Daiichi-Sankyo, Torrent, Cristalia, and Janssen.

Background: Many patients critically ill with COVID-19 develop acute respiratory distress syndrome (ARDS) necessitating mechanical ventilation and proning. Although proning is lifesaving, it has been linked to the occurrence of facial pressure injuries (PIs)., Objectives: To evaluate the incidence and use of prevention strategies and identify predictors of facial PIs in patients who received ventilator and proning treatments in COVID-designated intensive care units at 2 large quaternary medical centers in the Midwest., Method: This was a retrospective cohort study using data extracted from an electronic health record between October 2020 and February 2022. Demographics, clinical and care variables, and PI outcomes were analyzed to identify predictors of PI using logistic and Cox regression., Results: The cohort (N = 150) included patients from 2 units, unit a (n = 97) and unit b (n = 53) with a mean age of 60 years, with 68% identifying as male. Patients were vented for an average of 18 (SD, 16.2) days and proned for an average of 3 (SD, 2.5) days. Many (71%) died. Over half (56%) developed facial PI with a proning-exposure-adjusted incidence rate of 18.5%. Patients with PI were significantly different in several factors. Logistic regression showed predictors of PIs were duration of mechanical ventilation (in days; P = .02) and head turned (P = .01). Cox regression also identified head turn as predictive (P < .01), with Black/African American race as protective (P = .03)., Discussion: Critically ill patients with COVID-19 receiving ventilator and proning therapy developed facial PIs despite the use of recommended prevention practices. Further research on effective PI prevention strategies is needed., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Background: The suspension of breast cancer screening during the COVID-19 pandemic altered patient diagnosis and management. This study investigates the impact of the COVID-19 lockdowns, screening delays and reduced healthcare attendance on changes in tumour and treatment characteristics, particularly for biologically more aggressive breast cancers., Methods: This retrospective single-hospital analysis utilized data from a prospective cancer database between July 2019 and June 2022. Patient, tumour and treatment factors were compared across pre-pandemic, pandemic and post-pandemic groups., Results: Symptomatic breast cancer increased from 42.3% in the pre-, 53.1% in the pandemic and 57% in the post- respectively (P ≤ 0.05). Compared to the pre-pandemic group (4.6%), an increase in stages 3 or 4 breast cancers in the pandemic (8.5%) and post-pandemic (7.1%) was found. Increased node-positivity in Ki67 > 20%, grade 3 or ER- tumours post-pandemic (+5.4%, +14.8%, +33.4%, respectively) was identified. More neoadjuvant chemotherapy was found in both the pandemic (+4.3%) and post-pandemic (+11.3%, P = 0.0261) groups. An increase in hypofractionated radiotherapy in the post-pandemic group (+9.4%) was also identified., Conclusion: Our study identified a decrease in early-stage cancers and an increase in node positivity, particularly for biologically more aggressive tumours. An increase in the number of patients receiving neoadjuvant chemotherapy or hypofractionated radiotherapy during the pandemic and post-pandemic periods was also identified., (© 2024 The Authors.

To this date, COVID-19 remains an unresolved pandemic, and the impairment of redox homeostasis dictates the severity of clinical outcomes. Here we examined initial UCLA cohort of 440 COVID-19 patients hospitalized between March 1 st and April 1 st , 2020, representing the first wave of the pandemic. The mean age was 58.88 ± 21.12, among which males were significantly more than females (55.5 % vs. 44.5 %), most distinctively in age group of 50-69. The age groups of 50-69 (33.6 %) and ≥70 (34.8 %) dominated. The racial composition was in general agreement with Census data with slight under-representation of Hispanics and Asians, and over-representation of Caucasians. Smoking was a significant factor (28.8 % vs. 11.0 % in LA population), likewise for obesity (BMI ≥30) (37.4 % vs. 27.7 % in LA population). Patients suffering from obesity or BMI<18.5 checked into ICU at a significantly higher rate. A 74.5 % of the patients had comorbidities including diabetes, chronic kidney disease, chronic pulmonary disease, congestive heart failure and peripheral vascular disease. The levels of d-dimer were drastically upregulated (1159.5 ng/mL), indicating hypercoagulative state. Upregulated LDH (328 IU/L) indicated significant tissue damages. A distorted redox hemeostasis is a common trait associated with these risk factors and clinical markers. A quarter of the patients received antivirals, among which Remdesivir most prescribed (23.6 %). Majority received antithrombotics (75 %), and antibiotics. Upon admission, 67 patients were intubated or received CPR; 177 patients eventually received intensive care (40.2 %). While 290 were discharged alive, 10 remained hospitalized, 73 were transferred, and 36 died with 3 palliatively discharged. In summary, our data fully characterized a Californian cohort of COVID-19 at the breaking phase of the pandemic, indicating that population demographics, biophysical characters, comorbidities and molecular pathological parameters have significant impacts on the evolvement of a pandemic. These provide critical insights into effective management of COVID-19, and future break from another pathogen., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Purpose: To elucidate the impact of long COVID on menstruation and mental health, medical records of patients with long COVID were evaluated., Methods: Symptoms of long COVID, QOL, mental health, and related endocrine data were compared between two groups with and without menstrual disturbances., Results: Of 349 female patients who visited our clinic between February 2021 and March 2023, 223 patients with long COVID (aged 18-50 years) were included. Forty-four (19.7%) of the patients had menstrual symptoms associated with long COVID. The patients with menstrual symptoms were older than those without menstrual symptoms (42.5 vs. 38 years). The percentage of patients with menstrual symptoms was higher during the Omicron phase (24%) than during the Preceding (13%) and Delta (12%) phases. Cycle irregularity was the most frequent (in 63.6% of the patients), followed by severe pain (25%), heavy bleeding (20.5%), perimenopausal symptoms (18.2%), and premenstrual syndrome (15.9%). Fatigue and depression were the most frequent complications. Scores for fatigue and for QOL were significantly worse in long COVID patients with menstrual symptoms. Results of endocrine examinations showed significantly increased cortisol levels in patients with menstrual complaints., Conclusion: Long COVID has an impact on menstrual conditions and on QOL related to menstrual conditions.

Background: To investigate and analyze various aspects related to patients who have been placed on a "turndown list" for elective or emergency repair of abdominal aortic aneurysms., Methods: This retrospective study analyzed data from the Black Country Vascular Network. Multidisciplinary team meetings assessed abdominal aortic aneurysm patients referred through National Abdominal Aortic Aneurysm Screening Program or directly to vascular surgery. Patients considered unfit for intervention were added to a prospectively kept turndown list. Survival and cause of death data were collected, along with cardiopulmonary exercise testing (CPET) results and British Aneurysm Repair scores for some patients. The study covered a period from January 2015 to May 2023., Results: After exclusions, 247 (16%) patients were placed on the turndown list with a median age of 85 years (interquartile range 8 years). The mortality of turndown cases on medical grounds was 74.1%. Survival was significantly higher for patients who completed CPET before being turned down (P = 0.004). Gender analysis revealed a higher proportion of females being turned down compared to males (P = 0.044). COVID-19 led to a notable reduction in the number of discussed cases and interventions, while the turndown rates remained consistent. Survival at 1 year in turndown patients was 66%, at 3 years it was 29%, at 4 years it was 18%, and at 7 years it was 5%. Most patients whose cause of death was known died of respiratory complications (30%) or malignancy (19%). British Aneurysm Repair scores and aneurysm size were not significant predictors of mortality., Conclusions: Patients on the turndown list have a substantial mortality rate. A significant proportion of female patients were being turned down compared to men and the reasons for this are not clear. Patients who completed CPET before being turned down had a longer survival time. While COVID-19 impacted healthcare services reducing the number of interventions, it did not influence turndown decisions. The study showed that the cause of death for a significant number of patients was respiratory complications or malignancy., (Copyright © 2024. Published by Elsevier Inc.)

Objective: We aimed to investigate the clinical findings of hospitalized paediatric COVID-19 patients by the end of 2022., Method: All confirmed children with COVID-19 infection admitted into Chaozhou Central Hospital during the COVID-19 outbreak from 19 December 2022 to 1 February 2023 were included. Detailed clinical data of those children were evaluated retrospectively., Results: A total of 286 children, ranging in age from 1 month to 13 years old, were diagnosed with SARS-CoV-2 infection. Among these cases, 138 (48.3%) were categorized as mild, 126 (44.0%) as moderate and 22 (7.7%) as severe/critical. Symptoms varied among the children and included fever, upper respiratory tract symptoms, convulsions, sore throat, poor appetite, dyspnoea and gastrointestinal symptoms. Notably, febrile convulsions were observed in 96 (33.6%) patients, while acute laryngitis was documented in 50 (17.5%) cases. Among the severe/critical patients, eight developed multisystem inflammatory syndrome in children (MIS-C), and tragically, one patient's condition worsened and resulted in death. Furthermore, MRI scans revealed abnormal brain signals in six severe/critical patients. The severe/critical group also exhibited more pronounced laboratory abnormalities, including decreased haemoglobin and elevated ALT, AST, LDH and CK levels., Conclusions: Febrile convulsions and acute laryngitis are frequently observed in children diagnosed with SARS-CoV-2 Omicron infection. Moreover, MIS-C and abnormal neuroimaging appear to be relatively common phenomena in severe/critical cases.

The limited literature on the clinical course of COVID-19 among patients with underlying liver disease (LD) is available from India. The present study aimed to evaluate the clinical and mutational profile of SARS-CoV-2 among LD cases. This was a retrospective study including admitted LD cases in whom SARS-CoV-2 RT-PCR testing was performed. Complete demographic and clinical details were retrieved from Hospital Information System. Detailed mutational analysis was performed by comparing LD COVID-19 positive study group, i.e. LD-CoV(+) with COVID-19 positive outpatients without any underlying LD as control, i.e. NLD-CoV(+). Out of 232 enrolled LD cases, 137 (59.1%) were LD-CoV(+). LD cases with existing co-morbidities were affected more (P = 0.002) and had 2.29 times (OR 2.29, CI 95%, 1.25-4.29) higher odds of succumbing to COVID-19 (P = 0.006). On multivariate regression analysis, ascites (P = 0.05), severe COVID-19 pneumonia (P = 0.046), and an increased levels of bilirubin (P = 0.005) and alkaline phosphatase (P = 0.003) were found to be associated with adverse outcome in LD-CoV(+).On mutational analysis, we found certain differences between LD- and NLD-CoV(+) infected with Delta [LD- and NLD-CoV (+ /D)] and Omicron [LD- and NLD-CoV(+/O)]. More mutations were shared between LD- and NLD-CoV(+/O) compared to LD- and NLD-CoV(+/D). There were differences in prevalence of indel mutations specific to LD-CoV ( +) for both Delta and Omicron. Moreover, we also reported an interesting genic bias between LD- and NLD-CoV( +) in harbouring deleterious/tolerated mutations. To conclude, LD cases with comorbidities were affected more and had higher odds of mortality due to COVID-19. The definite difference between LD- and NLD-CoV(+) groups with respect to frequency of harboured mutations and an inherent genic bias between them is of noteworthy importance., (© 2024.

Objectives: To assess whether the coronavirus disease (COVID-19) pandemic affected the outcomes of robot-assisted radical prostatectomy (RARP) and urologists' treatment behaviors., Methods: We retrospectively examined the medical records of 208 patients who had undergone RARP between August 2017 and December 2022. We compared the rate of preoperative androgen deprivation therapy (ADT), waiting period for RARP, patients' baseline characteristics and quality of life (QOL), proportion of adverse pathology on the RARP specimen, rate of Gleason grade group upgrading from biopsy to the RARP specimen, and prostate-specific antigen (PSA) recurrence-free survival between the pre-pandemic and pandemic groups., Results: The rate of preoperative ADT was significantly higher during than before the COVID-19 pandemic (13.7% vs. 1.9%; p = 0.002). The baseline physical and mental QOL scores did not differ significantly between the groups. The proportion of D'Amico low-risk patients was significantly lower (13.6% vs. 1.2%, p = 0.005) and waiting period for RARP was significantly shorter (median 3.5 months vs. 4.0 months, p = 0.016) in the pandemic group than in the pre-pandemic group. There was no significant difference in the proportion of adverse pathology between the groups (p = 0.104); however, the upgrading rate was significantly higher in the pre-pandemic group (p = 0.002). There was no significant difference in PSA recurrence-free survival between the groups (log-rank, p = 0.752)., Conclusions: The COVID-19 pandemic did not adversely affect the oncologic outcomes of RARP and QOL before RARP. However, it caused urologists to increase the use of preoperative ADT and to reserve RARP for higher-risk cases., (© 2024 The Japanese Urological Association.)

Purpose: The COVID-19 pandemic has notably altered the infection dynamics of various pathogens. This study aimed to evaluate the pandemic's impact on the infection spectrum of Mycoplasma pneumoniae (M. pneumoniae) among children with community acquired pneumonia (CAP)., Methods: We enrolled pediatric CAP patients admitted to a tertiary hospital in southwest China to compare the prevalence and characteristics of M. pneumoniae infections before (2018-2019) and during (2020-2022) the COVID-19 pandemic. Detection of M. pneumoniae IgM antibodies in serum were conducted using either indirect immunofluorescence or passive agglutination methods., Results: The study included 1505 M. pneumoniae-positive and 3160 M. pneumoniae-negative CAP patients. Notable findings were the higher age and frequency of pneumonia-associated symptoms in M. pneumoniae-positive patients, alongside a lower male proportion and fewer respiratory co-infections. The year 2019 saw a notable increase in M. pneumoniae infections compared to 2018, followed by a decline from 2020 to 2022. The COVID-19 pandemic period witnessed significant alterations in age distribution, male proportion, and co-infections with specific pathogens in both M. pneumoniae-positive and negative patients. The M. pneumoniae infections were predominantly seasonal, peaking in autumn and winter during 2018 and 2019. Although there was a sharp drop in February 2020, the infection still peaked in cold months of 2020 and 2021. However, the typical seasonal pattern was nearly absent in 2022., Conclusions: The COVID-19 pandemic has markedly changed the infection landscape of M. pneumoniae in pediatric CAP patients, with shifts observed in infection rates, demographic profiles, co-infections, and seasonal patterns., (© 2024.

The ongoing coronavirus disease 2019 (COVID-19) pandemic presents serious public health threats. Omicron, the current most prevalent strain of COVID-19, has a low fatality rate and very high transmissibility, so the number of patients with mild symptoms of COVID-19 is rapidly increasing. This change of pandemic challenges medical systems worldwide in many aspects, including sharp increases in demands for hospital infrastructure, critical shortages in medical equipment, and medical staff. Predicting deterioration in mild patients could alleviate these problems. A novel scoring system was proposed for predicting the deterioration of patients whose condition may worsen rapidly and those who all still mild or asymptomatic. Retrospective cohorts of 954 and 2,035 patients that quarantined in the Residential Treatment Center were assembled for derivation and external validation of mild COVID-19, respectively. Deterioration was defined as transfer to a local hospital due to worsening condition of the patients during the 2-week isolation period. A total of 15 variables: sex, age, seven pre-existing conditions (diabetes, hypertension, cardiovascular disease, respiratory disease, liver disease, kidney disease, and organ transplant), and five vital signs (systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), body temperature, and oxygen saturation (SpO2)) were collected. A scoring system was developed using seven variables (age, pulse rate, SpO2, SBP, DBP, temperature, and hypertension) with significant differences between the transfer and not transfer groups in logistic regression. The proposed system was compared with existing scoring systems that assess the severity of patient conditions. The performance of the proposed scoring system to predict deterioration in patients with mild COVID-19 showed an area under the receiver operating characteristic (AUC) of 0.868. This is a statistically significant improvement compared to the performance of the previous patient condition assessment scoring systems. During external validation, the proposed system showed the best and most robust predictive performance (AUC = 0.768; accuracy = 0.899). In conclusion, we proposed a novel scoring system for predicting patients with mild COVID-19 who will experience deterioration which could predict the deterioration of the patient's condition early with high predictive performance. Furthermore, because the scoring system does not require special calculations, it can be easily measured to predict the deterioration of a patients' condition. This system can be used as effective tool for early detection of deterioration in mild COVID-19 patients., (© 2024. The Author(s).)

Objective: We investigated the risk factors associated with severe or critical Coronavirus disease 2019 (COVID-19) infection due to the Omicron variant in patients with myasthenia gravis (MG) and determined the potential effect of COVID-19 on myasthenic exacerbation during the Omicron pandemic., Methods: This retrospective study included 287 patients with MG in Tianjin, China. Clinical data of the patients were collected using electronic questionnaires, databases, and clinical records., Results: The overall infection rate was 84.7%. Advanced age, comorbidities, generalized phenotype, and MG instability were drivers of COVID-19 severity, and post-COVID-19 myasthenic exacerbation. The concurrent use of a steroid-sparing agent did not affect COVID-19 susceptibility or severity. It did lower the risk of myasthenic exacerbation after COVID-19 infection. Patients with severe COVID-19 experienced myasthenic exacerbation earlier than patients with non-severe infection ( p  < 0.001). The severity of COVID-19 (Hazards Ratio = 3.04, 95% CI: 1.41-6.54, p  = 0.004) and the clinical phenotype (Hazards Ratio = 3.29, 95% CI: 1.63-6.63, p  < 0.001) emerged as independent risk factors for early MG exacerbation., Conclusion: Generally, patients with MG appear to be susceptible to the Omicron strains. Immunotherapy for MG did not increase COVID-19 susceptibility or severity. We do not advocate an immediate cessation of ongoing immunosuppressive treatments once a COVID-19 infection is diagnosed. Instead, a judicious evaluation of the risks and benefits, tailored to each individual, is recommended., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Li, Xu, Qin, Liu, Guo, Huang, Fan, Zhang, Qi, Zhang, Yang, Shi and Yang.)

Background: The COVID-19 pandemic has underscored the critical role of sequencing technology in disease control and outbreak response. However, resource limitations and challenging environments often impede such efforts in low and middle-income countries. This study aimed to investigate the spectrum of viral co-infections, particularly with human viral pathogens, in SARS-CoV-2 positive individuals in Sierra Leone using metagenomic sequencing, evaluating the feasibility of utilizing this technology for epidemiological and evolutionary surveillance of pathogens related to public health in low-income environments., Methods: We retrospectively collected and analyzed 98 nasopharyngeal swab specimens from SARS-CoV-2 positive individuals in Sierra Leone. Samples were pre-processed locally and transferred to China via FTA cards for metagenomic sequencing, which was performed using the Novaseq platform. The study focused on the identification of nasopharyngeal viruses co-infecting with SARS-CoV-2, with a deeper analysis of significant human viral pathogens such as HPV., Results: The study identified 22 viral taxa from 20 families, including 4 human viruses. Notably, 19.4% of samples showed HPV co-infection with 34 distinct types, predominantly beta and gamma HPVs. Multiple HPV types were found in individual samples, indicating a high complexity of viral co-infections., Conclusions: The identification of a wide range of co-infecting viruses, particularly multiple HPV genotypes, highlights the complexity of viral interactions and their potential implications for public health. These findings enhance our understanding of viral co-infections and provide valuable insights for public health interventions in Sierra Leone. Further research is needed to explore the clinical significance of these findings and their impact on disease outcomes., (© 2024. The Author(s).)

Background: COVID-19 caused widespread disruptions to health services worldwide, including reductions in elective surgery. Tooth extractions are among the most common reasons for elective surgery among children and young people (CYP). It is unclear how COVID-19 affected elective dental surgeries in hospitals over multiple pandemic waves at a national level., Methods: Elective dental tooth extraction admissions were selected using Hospital Episode Statistics. Admission trends for the first 14 pandemic months were compared with the previous five years and results were stratified by age (under-11s, 11-16s, 17-24s)., Results: The most socioeconomically deprived CYP comprised the largest proportion of elective dental tooth extraction admissions. In April 2020, admissions dropped by >95%. In absolute terms, the biggest reduction was in April (11-16s: -1339 admissions, 95% CI -1411 to -1267; 17-24s: -1600, -1678 to -1521) and May 2020 (under-11s: -2857, -2962 to -2752). Admissions differed by socioeconomic deprivation for the under-11s (P < 0.0001), driven by fewer admissions than expected by the most deprived and more by the most affluent during the pandemic., Conclusion: Elective tooth extractions dropped most in April 2020, remaining below pre-pandemic levels throughout the study. Despite being the most likely to be admitted, the most deprived under-11s had the largest reductions in admissions relative to other groups., (© The Author(s) 2024.

Background: Post-acute COVID-19 syndrome (long COVID) refers to the persistence of COVID-19 symptoms or exceptional symptoms following recovery. Even without conferring fatality, it represents a significant global public health burden. Despite many reports on long COVID, the prevalence and data on associated biological factors remain unclear and limited. This research aimed to determine the prevalence of long COVID during the two distinct epidemic periods in Thailand, due to the Delta and Omicron variants of SARS-CoV-2, and to investigate the biological factors associated with long COVID. In addition, the spike protein amino acid sequences of the Delta and Omicron variants were compared to determine the frequency of mutations and their potential biological implications., Methods: A retrospective cross-sectional study was established to recruit confirmed COVID-19 participants at Maharat Nakhon Ratchasima Hospital who had recovered for at least three months and were infected between June 2021 and August 2022. The demographic data and long COVID experience were collected via telephone interview. The biological factors were analyzed through binary logistic regression. The datasets of the SARS-CoV-2 spike protein amino acid sequence of the Delta and Omicron variants in Thailand were retrieved from GIDSAID to determine mutation frequencies and to identify possible roles of the mutations based on published data., Results: Data was collected from a total of 247 participants comprising 106 and 141 participants of the Delta and Omicron epidemic periods, respectively. Apart from the COVID-19 severity and health status, the baseline participant data of the two time periods were remarkably similar. The prevalence of long COVID observed in the Omicron period was higher than in the Delta period (74.5% vs . 66.0%). The biological factors associated with long COVID were epidemic variant, age, treatment with symptomatic medicines, and vaccination status. When the spike protein sequence data of the two variants were compared, it was observed that the Omicron variant exhibited a greater quantity of amino acid changes in its receptor-binding domain (RBD) and receptor-binding motif (RBM). The critical changes of the Omicron variant within these regions had a significant function in enhancing virus transmissibility and host immune response resistance., Conclusion: This study revealed informative data associated with long COVID in Thailand. More attention should be given to long COVID caused by unique virus variants and other biological factors to prepare a healthcare management strategy for COVID-19 patients after recovery., Competing Interests: The authors declare there are no competing interests., (©2024 Kiatratdasakul et al.)

Introduction: Comorbidities such as hypertension, diabetes mellitus, asthma, and cardiovascular conditions have been reported to worsen the clinical progression of coronavirus disease 2019 (COVID-19) and related hospitalizations. Furthermore, the COVID-19 pandemic has disproportionately affected the historically marginalized groups, i.e., Black, Hispanic, and Asian individuals have substantially higher rates of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection, COVID-19 hospitalization, and death compared to White individuals. Despite these findings in civilian populations, the impact of comorbidities and race in SARS-CoV-2 infection and COVID-19 hospitalizations in military populations is unknown. We evaluated the relationship of pre-selected pre-pandemic comorbidities and race with SARS-CoV-2 infections and COVID-19 hospitalizations in U.S. military service members (SMs)., Materials and Methods: We conducted a systematic review of Military Health System beneficiaries' records by accessing the Defense Medical Epidemiological Database. Our inclusion criteria were being an active duty SM and having at least one pre-COVID-19 pandemic comorbidity. Retired as well as uninfected healthy active duty SMs and beneficiaries were excluded from the study. A total population of 1.334 million active duty SM records was drawn from Defense Medical Epidemiological Database. The data were stratified, by race (primary outcome), as well as gender, age, and military service branches (secondary outcomes)., Results: We found higher trends in SARS-CoV-2 infection and COVID-19 hospitalization rates in Black compared to White SMs. This seamless inequality was also seen in other viral infections affecting SMs including human immunodeficiency virus and viral hepatitis. We hypothesized this disparity to some extent be associated with the presence of pre-pandemic comorbidities that is affecting this military subpopulation. Supporting our hypothesis, we found trends toward the higher pre-pandemic prevalence of diabetes mellitus, asthma, hypertension, and ischemic heart disease, in Black compared to White military SMs, especially in Black older male adults., Conclusion: Our results highlight the role of pre-pandemic comorbidities and race likely enhancing the frequency of SARS-CoV-2 infections and COVID-19 hospitalizations in military SMs. These preliminary findings underscore the need for future retrospective studies using additional Military Health System data bases reporting data on this military subpopulation, especially in the setting of future pathogens outbreaks or pandemics affecting military populations., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2024.

Multiple factors, from socioeconomic development to genetic background, can affect the regional impact of some diseases, and this has also been seen during the COVID-19 pandemic. The objective of this retrospective study was to characterize a population in the interior of Portugal regarding health status and COVID-19 epidemiology. Between October 2021 and January 2023, 1553 subjects residing in Beira Baixa, Portugal, were included. Using a self-report approach, demographic and clinical data were obtained. Blood group, blood pressure, peripheral oxygen saturation and anti-spike protein immunoglobulin concentration were also analyzed. Statistical analysis was performed using IBM SPSS Statistics. The average age of the participants was 48.95 (±14.43) years, with 64% being male and 36% being female. The most prevalent comorbidities were hypertension (19.2%), dyslipidemia (12.6%) and diabetes mellitus (6.6%). Half of the population was overweight, and more than half of the subjects had no history of tobacco consumption. Among the participants, 33% were infected with SARS-CoV-2: 70.1% had mild disease, 14.1% moderate disease and 1.4% severe disease. There was a very significant adherence to vaccination (97%). Previously infected or vaccinated people had higher anti-spike protein immunoglobulin values; this value depended on the vaccine administered ( p < 0.001). Patients with autoimmune diseases and smokers had lower levels of anti-S IgG antibodies ( p = 0.030 and p = 0.024, respectively). The severity of COVID-19 did not affect the concentration of anti-S IgG ( p = 0.430). This study highlights the general health statuses and the impact of COVID-19 on a population in the Portuguese interior. Knowledge of the circulation and impact of the virus in this specific population can alert and assist in better interventions being conducted by health authorities.

Coronavirus disease 2019 (COVID-19) is characterized by an acute respiratory infection with multisystem involvement and the association of its severity to liver function abnormalities is not well characterized. The aim of this study was to assess the association between the severity of COVID-19 patients and liver function abnormalities. This retrospective study included adult patients with confirmed COVID-19, which were classified as non-severe or severe according to World Health Organization guidelines. Liver function test results were compared between the severity groups. A total of 339 patients were included of which 150 (44.25%) were severe cases. The male-to-female ratio was 0.9:1 and 3:2 in the non-severe and severe groups, respectively ( p =0.031). Aspartate aminotransferase (AST), alanine transaminase (ALT), and total bilirubin levels and acute liver injury (ALI) incidence were significantly higher in the severe group compared to non-severe group ( p <0.001, p <0.001, p =0.025, p =0.014, respectively). In contrast, albumin levels were significantly lower ( p =0.001). Multivariate analysis showed that ALI was significantly associated with human immunodeficiency virus (HIV) infection (odds ratio (OR): 5.275; 95% confidence interval (CI): 1.165-23.890, p =0.031), hemoglobin level (OR: 1.214; 95%CI: 1.083-1.361, p =0.001), and hypoalbuminemia (OR: 2.627; 95%CI: 1.283-5.379, p =0.008). Pre-existing liver diseases were present in 6.5% of patients. No significant differences were observed between the groups based on COVID-19 severity and ALI presence. Liver function test abnormalities, including ALI, are more prevalent in patients with severe COVID-19 infection. HIV infection, high hemoglobin levels, and hypoalbuminemia may be potential risk factors for ALI., Competing Interests: All the authors declare that there are no conflicts of interest., (© 2024 The Author(s).)

Background: Systemic inflammation stands as a pivotal factor tightly interwoven with the progression of COVID-19. This study endeavors to elucidate the significance of three key inflammatory molecules, that is, heparin-binding protein (HBP), interleukin-6 (IL-6), and C-reactive protein (CRP), in assessing the severity and prognostic implications of COVID-19., Methods: The demographic, clinical, and laboratory data were retrospectively collected from a cohort of 214 adult patients diagnosed with COVID-19. Patients were divided into two groups: nonsevere (n = 93; 43.5%) and severe (n = 121; 56.5%). Additionally, based on their organ function, patients were categorized into nonorgan failure (n = 137) and organ failure (n = 77) groups. The levels of inflammation-related cytokines were then compared among these defined groups., Results: The severe group was characterized by a higher proportion of males, older age, and longer hospital stays compared to nonsevere cases. Additionally, severe cases exhibited a higher prevalence of underlying diseases and organ failure. Statistical analysis revealed significantly elevated levels of HBP, IL-6, and CRP in the severe group. HBP, IL-6, and CRP were identified as independent risk factors for severe COVID-19. Furthermore, a combined assessment of these biomarkers demonstrated superior diagnostic sensitivity (85.10%) and specificity (95.70%) for predicting COVID-19 severity. A positive relationship between elevated HBP, IL-6, and CRP levels and impaired organ function was also observed. The predictive efficiency significantly increased (hazard ratio = 3.631, log-rank p = 0.003) when two or more of them were combinedly used. Notably, elevated levels of HBP, IL-6, and CRP were associated with an increased risk of mortality., Conclusions: In conclusion, the combined assessment of HBP, IL-6, and CRP offers enhanced accuracy and specificity in predicting the severity, organ failure, and mortality risk associated with COVID-19., (© 2024 The Author(s).

Objective: To investigate the association between the duration of the first prone positioning maneuver (PPM) and 90-day mortality in patients with C-ARDS., Design: Retrospective, observational, and analytical study., Setting: COVID-19 ICU of a tertiary hospital., Patients: Adults over 18 years old, with a confirmed diagnosis of SARS-CoV-2 disease requiring PPM., Interventions: Multivariable analysis of 90-day survival., Main Variables of Interest: Duration of the first PPM, number of PPM sessions, 90-day mortality., Results: 271 patients undergoing PPM were analyzed: first tertile (n = 111), second tertile (n = 95) and third tertile (n = 65). The results indicated that the median duration of PDP was 14 h (95% CI: 10-16 h) in the first tertile, 19 h (95% CI: 18-20 h) in the second tertile and 22 h (95% CI: 21-24 h) in the third tertile. Comparison of survival curves using the Logrank test did not reach statistical significance (p = 0.11). Cox Regression analysis showed an association between the number of pronation sessions (patients receiving between 2 and 5 sessions (HR = 2.19; 95% CI: 1.07-4.49); and those receiving more than 5 sessions (HR = 6.05; 95% CI: 2.78-13.16) and 90-day mortality., Conclusions: while the duration of PDP does not appear to significantly influence 90-day mortality, the number of pronation sessions is identified as a significant factor associated with an increased risk of mortality., (Copyright © 2024 Elsevier España, S.L.U. and SEMICYUC.
