Abstract Background Abdominal pain in adults represents a wide range of illnesses, often warranting immediate intervention. This study is to fill the gap in the knowledge about incidence, presentation, causes and mortality from abdominal pain in an established emergency department of a tertiary hospital in Tanzania. Methods This was a prospective cohort study of adult (age ≥ 18 years) patients presenting to the Emergency Medicine Department of Muhimbili National Hospital (EMD-MNH) in Dar Es Salaam, Tanzania with non-traumatic abdominal pain from September 2017 to October 2017. A case report form was used to record data on demographics, clinical presentation, management, diagnosis, outcomes and patient follow-up. The primary outcome of mortality was summarized using descriptive statistics; secondary outcome was, risks for mortality. Results Among 3381 adult patients present during the study period, 288 (8.5%) presented with abdominal pain, and of these 199 (69%) patients were enrolled in our study. Median age was 47 years (IQR 35–60 years), 126 (63%) were female, and 118 (59%) were referred from another hospital. Most common final diagnoses were malignancies 71 (36%), intestinal obstruction 11 (6%) and peptic ulcer disease 9 (5%). Most common EMD interventions given were intravenous fluids 57 (21%), analgesia 49 (25%) and antibiotics 40 (20%). 160 (80%) were admitted of which 15 (8%) underwent surgery directly from EMD. 24-h and 7-day mortality were 4 (2%) and 7 (4%) respectively, while overall in hospital-mortality was 16 (8%). Among the risk factors for mortality were male sex Relative Risk (RR) 2.88 (p = 0.03), hypoglycemia (RR) 5.7 (p = 0.004), ICU admission (RR) 14 (p

Abstract Background Non-traumatic chest pain (NTCP) is a common reason for emergency department (ED) attendance in high-income countries, with the primary concern focused on life threatening cardiovascular diseases. There is general lack of data on aetiologies, diagnosis and management of NTPC in Sub Sahara African (SSA) countries. We aimed to describe evaluation, diagnosis and outcomes of adult patients presenting with NTCP to an urban ED in Tanzania. Method This was a prospective observational cohort study of consecutive adult (≥18 years) patients presenting with non-traumatic chest pain to the Emergency Medicine Department (EMD) of Muhimbili National Hospital (MNH) in Dar es salaam from September 2017 to April 2018. Structured case report form was used to collected demographics, clinical presentation, investigations, diagnosis, and EMD disposition and in hospital mortality. We determined frequency of NTCP among our patients, aetiologies, 24-h and 7-day in-hospital mortality, and predictors for mortality. Results We screened 29,495 adults attending EMD-MNH during the study and 389 (1.3%) presented with NTCP of these, 349 (90%) were enrolled. The median age was 45 (IQR 29–60) years and 177 (50.7%) were female. Overall, 69.1% patients received electrocardiography (ECG) in the EMD and 34.1% had a troponin test. Heart failure and pulmonary tuberculosis (PTB) were the leading hospital diagnoses (12.6% each), followed by chronic kidney disease (10%) and acute coronary syndrome (ACS) (9.6%). Total of 167 (48%) patients were admitted, and the 24-h and 7-day in-hospital mortality were 5 (3%) and 16 (9.6%) respectively. Univariate risk factors for mortality were a Glasgow Coma Scale of 0.04 ng/ml [RR 2.9 (95%CI 1.2–7.3)]. Features distinguishing cardiovascular from other causes were: bradycardia [RR = 2.6 (95%CI 2.1–3.2)], heart beat awareness [RR = 2.3 (95%CI 1.7–3.2)] and history of diabetic mellitus [RR = 2.2 (95% CI 1.6–3.0)]. Conclusion In this ED of SSA country, heart failure and pulmonary tuberculosis were the leading causes of NCTP, and ACS was present in 9.6%. NTCP in this setting carries high mortality, and ACS was the leading risk factor for death. ED providers in SSA must increasingly consider cardiovascular causes of NTCP.

Abstract Background Marburg virus disease (MVD) is a deadly illness caused by the zoonotic Marburg virus, which has led to outbreaks with fatality rates up to 100% in some African countries. On March 21, 2023, Tanzania had its first MVD outbreak, resulting in nine cases and six deaths, leading to a fatality rate of 66.7%. Following that, the Risk Communication and Community Engagement (RCCE) approach was promptly initiated to create community awareness regarding the MVD. A descriptive cross-sectional assessment was conducted in May 2023 in Bukoba District Council and Bukoba Municipal Council in the Kagera region to document the community awareness and sources of information regarding MVD during the outbreak. Data were collected using a structured questionnaire developed using the WHO COVID-19 RCCE Rapid Quantitative Assessment Tool. Descriptive analysis was conducted using Microsoft Excel 2021. Results There were a total of 714 community respondents, of whom 456 (63.9%) were from Bukoba District Council. The majority 628 (88%) were aged 18 years and above. There were 393 (55%) females, and 407 (57%) of respondents had completed primary education. All respondents reported being informed about MVD through different channels, with 588 (82.4%) receiving information from Community Health Workers. Most of them 573 (80.3%) were satisfied with implemented RCCE interventions, 651 (91.2%) perceived MVD to be an extremely severe disease, and 698 (97.76%) mentioned hand washing as one of the recommended preventive measures. Conclusions During the Marburg virus disease outbreak response, where risk communication and community engagement interventions were implemented, the community was aware of the Marburg virus disease and community health workers emerged as the most frequently mentioned channel of communication during the outbreak.

Abstract Background Increased global trade, while beneficial economically, can also increase the spread of vector-borne diseases, particularly those transmitted by Aedes mosquitoes spreading via trade routes. Given the heightened trade-induced activity at ports of entry, it is particularly crucial to assess the risk of mosquito-borne diseases in these settings. This study compared the risks of Aedes-borne disease in and around the eastern Tanzanian seaport of Tanga. Methods A 200 m × 200 m grid-based system was used to sample mosquitoes within the port area, and in surrounding areas at 2 km, 2.5 km, and 5 km away, between June and December 2023. We characterized mosquito breeding habitats, collected mosquito larvae using standard dippers and tested susceptibility of raised adult Aedes aegypti populations to different insecticides. Adult mosquitoes were collected using BG sentinel traps (daytime) and Centers for Disease Control (CDC) light traps (night-time). Additionally, more than 200 port users and neighboring residents were surveyed to assess their experiences with and perceptions of mosquito biting and disease risks. Results There were 2931 breeding sites, with (60.8%, n = 1782) positive for Aedes larvae. The percentage of water-holding containers infested with Aedes immatures, i.e., the container index (CI), was highest in the port area (66.2%), and lowest 5 km away (44.6%). The port area also had a greater proportion of temporary breeding sites (64.9%) than did the surrounding areas. The adult mosquito surveys revealed 20,449 mosquito species including: Culex quinquefasciatus (56.2%), Mansonia uniformis (38.6%), Ae. aegypti (5.1%), Anopheles gambiae (0.1%), and Anopheles funestus. Ae. aegypti were more abundant in the port area than in the surrounding areas (P

Health risks associated with poor sanitation behaviours continue to be reported mostly from low-income countries (LICs). Reports show that various factors limit many people from accessing and using improved latrines, forcing some to opt for sharing latrines with neighbours, others practicing open defecation. Meanwhile, debate prevails on whether shared latrines should be categorised as unimproved according to WHO/UNICEF-JMP criteria. We contribute to this debate based on results from a study undertaken in three regions, Tanzania.Data were collected through observations in 1,751 households with latrines, coupled with collection of opinions from heads of such households regarding the latrine-sharing practices. Bivariate and multivariate logistic regression analyses were performed to assess associations between the outcome and possible predictor variables.Of all 1,751 latrines, 14.6% were shared. Among the shared latrines, 74.2% were found being generally clean as compared to 69.2% of the non-shared ones. Comparing the shared and non-shared latrines, the non-shared latrines were significantly less likely to be found with floors built with permanent materials (OR = 0.73, 95% CI: 0.55, 0.98); washable floors (OR = 0.69; 95% CI: 0.51, 0.93); and lockable doors (OR = 0.73; 95% CI: 0.56, 0.95). Shared latrines were less likely to have floors with faecal matter, functional handwashing facilities (HWFs), HWFs with running water, and roofs; albeit the differences in all these scenarios were not statistically significant. Respondents expressed desire for improved latrines, but also did not find it wrong to share latrines if cleanliness was maintained.Having an 'improved' latrine remains important as JMP recommends, but based on our study findings, we argue that possessing a non-shared latrine neither guarantees safety to its users nor its categorisation as 'improved'. Instead, the state of the latrine, the construction technology used and the behaviours of the users may be more important.

Background: Influenza can be associated with nonrespiratory disease presentation, but these are less well documented due to the lack of routine testing for influenza in the healthcare system, especially if patients do not present with influenza-like illness (ILI). We aimed to measure the proportion of influenza cases seeking care at emergency department (ED) for a nontraumatic cause, to describe their clinical presentation and their ED-discharge diagnosis., Methods: The study was conducted at seven hospitals in France, Spain, Italy and Germany during the 2019-20 influenza season, for a period of 10 weeks. Patients (≥ 18 years) consulting for nontraumatic causes at the ED were invited to participate. Consenting patients provided upper respiratory swab samples for influenza testing by reverse transcription polymerase chain reaction. Clinical and demographic data were collected., Results: There were 8678 patients included, 50.7% were female and the median age was 57 years. Among them, 494 (5.7%) were laboratory-confirmed influenza (LCI) cases. Nonetheless, only 24.3% of LCI cases had an ED-discharge of influenza. Of all cases confirmed as influenza, 47.6% had a nonrespiratory discharge diagnosis, which frequency increased with age. ILI case definition from the European Centre for Disease Prevention and Control was the most frequently met among influenza cases (68.6%). Older patients (≥ 65 years) were less frequently identified based on any ILI signs/symptoms., Conclusion: Our findings indicate that the impact of influenza among patients seeking care at the ED cannot be easily assessed based on clinical presentation and medical records alone. Preventing influenza among adult population may reduce healthcare utilization., (© 2024 The Author(s). Influenza and Other Respiratory Viruses published by John Wiley & Sons Ltd.)

Background: Literature is limited on the impact of patient vaccination on the risk of hospital-acquired influenza (HAI). This test negative case-control study nested in a surveillance program aimed at evaluating the effectiveness of influenza vaccination in reducing the risk of HAI in hospitalized patients during 15 influenza seasons (2004-05 to 2019-20)., Methods: HAI cases were those who developed influenza like illness (ILI) symptoms at least 72 h after hospitalization and had a positive reverse transcriptase-polymerase chain reaction (RT-PCR). Controls were those with ILI symptoms and a negative RT-PCR test. A nasal swab as well as socio-demographic, clinical data and information on influenza vaccination were collected., Results: Of the 296 patients included, 67 were confirmed HAI cases. Influenza vaccine coverage was significantly higher among controls compared to HAI cases (p = 0.002). The risk of HAI was reduced by almost 60 % in vaccinated patients., Conclusions: A better control of HAI can be achieved by vaccinating hospitalized patients., 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 © 2023 Elsevier Ltd.

Individuals with personality disorders (PDs) have a decreased life expectancy compared with the general population in part due to physical illnesses. Many hypotheses have been suggested to explain those physical illnesses such as hormone imbalance, medication, lack of physical activity, and unhealthy diet. However, little is known about the relation between lifestyle and PDs. The purpose of this scoping review is to regroup the available information on this topic. We searched the literature up to February 2021 using four databases and found 21 articles analyzing the relation between lifestyle and PDs in observational studies including 153,081 participants from diverse populations going from general population to adults in psychiatric care. Most studies used measures of lifestyle as control variables or did not use lifestyle variables at all. Moreover, the instruments used to measure lifestyle variables lacked precision at best. Two studies demonstrated a relation between early malnutrition and further development of PDs, but those results may be influenced by confounding variables and cannot indicate a clear link between nutrition and personality disorder. The lack of solid evidence we observed is surprising, considering the multiple benefits individuals with PDs could get from a healthy lifestyle. More studies are needed to thoroughly analyze the impact of lifestyle on PDs and vice versa., (© 2022 John Wiley & Sons Ltd.)

Background: Exposure to infected healthcare workers (HCWs) is a source of hospital-acquired (HA) influenza. We estimated the risk of HA influenza for hospitalized patients by rate of influenza vaccine coverage (IVC) of HCWs., Methods: A case-case negative control study nested in a prospective cohort was conducted in 2 French university hospitals during 2 influenza seasons. Each inpatient with influenza-like illness (ILI) provided a nasal swab sample that was systematically analyzed for influenza virus by polymerase chain reaction (PCR) testing. An HA influenza case was a patient with a virological confirmation of influenza with onset of symptoms ≥72 hours after admission to the ward. The IVC rate of HCWs in each participating ward was calculated from the data provided by the occupational health departments. A mixed-effect logistic regression was performed with adjustments on patient sex, age, the presence of a potential source of influenza on the ward in the 5 days prior to the start of the ILI, type of ward and influenza season., Results: The overall HA influenza attack rate was 1.9 per 1,000 hospitalized patients. In total, 24 confirmed HA influenza cases and 141 controls were included. The crude odds ratio (OR) of HA influenza decreased from 0.52 (95% confidence interval [CI], 0.21-1.29) to 0.14 (95% CI, 0.03-0.63) when the IVC of HCWs increased from 20% to 40%. After adjustment, IVC ≥40% was associated with a risk reduction of HA influenza (aOR, 0.07; 95% CI, 0.01-0.78)., Conclusions: Considering a limited sample size, influenza vaccination of HCWs is highly suggestive of HA flu prevention among hospitalized patients.Trial Registration: clinicaltrials.gov identifier: NCT02198638.

Introduction Borderline personality disorder (BPD) is associated with many unhealthy behaviors. Psychoactive substance (alcohol and drugs) use is present in 78% of adults with BPD. Moreover, a poor sleep seems linked to the clinical profile of adults with BPD. Finally, some physical comorbid disorders like obesity, cardiovascular diseases, and diabetes are linked to physical inactivity and sedentary behaviors. However, to this day no study analyzed these behaviors in French-speaking individuals with BPD. Objectives This study's goal is to document health behaviors in adults with BPD in Canada and in France. Method This cross-sectional study consists of an online survey on the LimeSurvey platform including validated questionnaires distributed in France and Canada. To measure physical activity, we used the "Global Physical Activity Questionnaire." Insomnia was measured with the "Insomnia Severity Index." Substance use was measured with the "Alcohol, Smoking and Substance Involvement Test." Descriptive statistics (N,% and mean) are used to describe previously mentioned health behaviors. Five regression models have been realized to find the main associated variables (age, perceived social status, education level, household income, body mass index, emotional regulation difficulties, BPD symptoms, depression level, previous suicide attempts and psychotropic medication use) to health behaviors. Results A total of 167 participants (92 Canadians, 75 French; 146 women, 21 men) filled out the online survey. In this sample, 38% of Canadians and 28% of French reported doing less than 150 minutes of physical activity weekly. Insomnia affected 42% of Canadians and 49% of French. Tobacco use disorder affected 50% of Canadians and 60% of French. Alcohol use disorder affected 36% of Canadians and 53% of French. Cannabis use disorder affected 36% of Canadians and 38% of French. All tested variables were linked to physical activity (R² = 0.09). Insomnia was only linked with BPD symptoms (R² = 0.24). Tobacco use disorder was linked to social status and alcohol use disorder (R² = 0.13). Alcohol use disorder was linked to social status, body mass index, tobacco use disorder, and depression (R² = 0.16). Finally, cannabis use disorder was linked to age, body mass index, tobacco use disorder, depression, and past suicide attempts (R² = 0.26). Conclusion These results are essential to design health prevention interventions in French-speaking adults with BPD in Canada and in France. They help identify the main factors associated with these health behaviors.

Background: Physical exercise is an evidence-based treatment to reduce symptoms and negative affect in several psychiatric disorders, including depressive, anxiety, and psychotic disorders. However, the effect of physical exercise on negative affect in patients with borderline personality disorder (BPD) has not yet been investigated. In this pilot study, we tested the safety, acceptability, and potential acute effects on negative affect of a single session of aerobic physical exercise in adults with BPD., Method: After completing a negative mood induction procedure, 28 adults with BPD were randomly assigned to a 20-minute single session of stationary bicycle or a control condition (emotionally neutral video)., Results: No adverse effects attributed to the physical exercise were reported and it was considered acceptable to patients. Following the negative mood induction, both conditions decreased the level of negative affect with a medium effect size but there was no significant difference between them., Conclusion: The results suggest that a single 20-minute session of physical exercise does not produce a reduction of negative affect in BPD. Future research should consider the duration and intensities of physical exercise with the greatest potential to reduce negative affect both acutely and in a more prolonged manner in this patient group., Competing Interests: The authors have declared that no competing interests exist.

The superior longitudinal fasciculus (SLF) is part of the longitudinal association fiber system, which lays connections between the frontal lobe and other areas of the ipsilateral hemisphere. As a dominant association fiber bundle, it should correspond to a well-defined structure with a clear anatomical definition. However, this is not the case, and a lot of confusion and overlap surrounds this entity. In this review/opinion study, we survey relevant current literature on the topic and try to clarify the definition of SLF in each hemisphere. After a comparison of postmortem dissections and data obtained from diffusion MRI studies, we discuss the specifics of this bundle regarding its anatomical landmarks, differences in lateralization, as well as individual variability. We also discuss the confusion regarding the arcuate fasciculus in relation to the SLF. Finally, we recommend a nomenclature based on the findings exposed in this review and finalize with a discussion on relevant functional correlates of the structure., 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 © 2022 Janelle, Iorio-Morin, D'amour and Fortin.)

Inaccurate perceptions, such as under- or over-estimation of body size are often found in clinical eating disorder populations but have recently been shown also in healthy people. However, it is not yet clear how body size perception may be affected when the internal body representation is manipulated. In this study, visual adaptation was used to investigate whether exposure to distorted visual feedback alters the representation of body size and how long any such effects might last. Participants were exposed for five minutes to a distorted life-size image of themselves that was either 20% wider or 20% narrower than their normal size. Accuracy was measured using our novel psychophysical method that taps into the implicit body representation. The accuracy of the representation was assessed at 6, 12 and 18 min following exposure to adaptation. Altered visual feedback caused changes in participants' judgements of their body size: adapting to a wider body resulted in size overestimation whereas underestimations occurred after adapting to a narrower body. These distortions lasted throughout testing and did not fully return back to normal within 18 min. The results are discussed in terms of the emerging literature indicating that the internal representation of the body is dynamic and flexible., Competing Interests: We declare we have no competing interests., (© 2022 The Authors.)

Inhaled corticosteroids (ICS) have been associated with increased risk of pneumonia. Their impact on respiratory virus infections is unclear. We performed a post-hoc analysis of the FLUVAC cohort, a multicenter prospective cohort study of adults hospitalized with influenza-like illness (ILI) during six consecutive influenza seasons (2012-2018). All patients were tested for respiratory virus infection by multiplex PCR on nasopharyngeal swabs and/or bronchoalveolar lavage. Risk factors were identified by logistic regression analysis. Among the 2658 patients included, 537 (20.2%) were treated with ICS before admission, of whom 282 (52.5%, 282/537) tested positive for at least one respiratory virus. Patients on ICS were more likely to test positive for non-influenza respiratory viruses (25.1% vs. 19.5%, P = 0.004), especially for adenovirus (aOR 2.36, 95% CI 1.18-4.58), and respiratory syncytial virus (aOR 2.08, 95% CI 1.39-3.09). Complications were reported in 55.9% of patients on ICS (300/537), primarily pneumonia (171/535, 32%). Among patients on chronic ICS who tested positive for respiratory virus, 14.2% (40/282) were admitted to intensive care unit, and in-hospital mortality rate was 2.8% (8/282). Chronic use of ICS is associated with an increased risk of adenovirus or RSV infections in patients admitted for ILI., (© 2022. The Author(s).)

Objectives: The purpose of this study was to describe the clinical characteristics and in-hospital and post-discharge outcomes of respiratory syncytial virus (RSV) infection among adults hospitalised with influenza-like illness (ILI) and compared against patients admitted for influenza., Methods: Adults hospitalised with ILI were prospectively included from five French university hospitals over two consecutive winter seasons (2017/2018 and 2018/2019). RSV and influenza virus were detected by multiplex reverse transcription PCR on nasopharyngeal swabs. RSV-positive patients were compared to RSV-negative and influenza-positive hospitalised patients. Poisson regression models were used to estimate the adjusted prevalence ratio (aPR) associated with in-hospital and post-discharge outcomes between RSV and influenza infections. The in-hospital outcome was a composite of the occurrence of at least one complication, length of stay ≥7 days, intensive care unit admission, use of mechanical ventilation and in-hospital death. Post-discharge outcome included 30- and 90-day all-cause mortality and 90-day readmission rates., Results: Overall, 1428 hospitalised adults with ILI were included. RSV was detected in 8% (114 of 1428) and influenza virus in 31% (437 of 1428). Patients hospitalised with RSV were older than those with influenza (mean age 73.0 versus 68.8 years, p=0.015) with a higher frequency of chronic respiratory or cardiac disease (52% versus 39%, p=0.012, and 52% versus 41%, p=0.039, respectively) and longer hospitalisation duration (median stay 8 versus 6 days, p<0.001). Anti-influenza therapies were less prescribed among RSV patients than influenza patients (20% versus 66%, p<0.001). In-hospital composite outcome was poorer in RSV patients (aPR 1.5, 95% CI 1.1-2.1) than in those hospitalised with influenza. No difference was observed for the post-discharge composite outcome (aPR 1.1, 95% CI 0.8-1.6)., Conclusion: RSV infection results in serious respiratory illness, with worse in-hospital outcomes than influenza and with similar midterm post-discharge outcomes., Competing Interests: Conflict of interest: N.

Introduction: Delay between symptom onset and access to care is essential to prevent clinical worsening for different infectious diseases. For COVID-19, this delay might be associated with the clinical prognosis, but also with the different characteristics of patients. The objective was to describe characteristics and symptoms of community-acquired (CA) COVID-19 patients at hospital admission according to the delay between symptom onset and hospital admission, and to identify determinants associated with delay of admission., Methods: The present work was based on prospective NOSO-COR cohort data, and restricted to patients with laboratory confirmed CA SARS-CoV-2 infection admitted to Lyon hospitals between February 8 and June 30, 2020. Long delay of hospital admission was defined as ≥6 days between symptom onset and hospital admission. Determinants of the delay between symptom onset and hospital admission were identified by univariate and multiple logistic regression analysis., Results: Data from 827 patients were analysed. Patients with a long delay between symptom onset and hospital admission were younger (p<0.01), had higher body mass index (p<0.01), and were more frequently admitted to intensive care unit (p<0.01). Their plasma levels of C-reactive protein were also significantly higher (p<0.01). The crude in-hospital fatality rate was lower in this group (13.3% versus 27.6%), p<0.01. Multiple analysis with correction for multiple testing showed that age ≥75 years was associated with a short delay between symptom onset and hospital admission (≤5 days) (aOR: 0.47 95% CI (0.34-0.66)) and CRP>100 mg/L at admission was associated with a long delay (aOR: 1.84 95% CI (1.32-2.55))., Discussion: Delay between symptom onset and hospital admission is a major issue regarding prognosis of COVID-19 but can be related to multiple factors such as individual characteristics, organization of care and severe pathogenic processes. Age seems to play a key role in the delay of access to care and the disease prognosis., Competing Interests: The authors have read the journal’s policy and have the following competing interests: PV received grants and fees from Anios, Pfizer, Astellas, MSD, Gilead and Sanofi.

Information gathered so far from published studies attest the existence of a complex relationship between tobacco smoking and the severity of COVID-19. We investigated the association between smoking habits and the severity of COVID-19 in patients hospitalized in university-affiliated hospitals in Lyon, France. Baseline sociodemographic, clinical and biological characteristics of adult COVID-19 hospitalized patients presenting from the community were prospectively collected and analyzed. Tobacco exposure was documented at admission. Characteristics of patients hospitalized in medical wards to those admitted or transferred to intensive care units (ICUs) were compared using Mann-Whitney and Χ 2 or Fisher's exact test. A composite endpoint including admission or transfer to ICU or death was created as a proxy for severe outcome. Adjusted odds ratio (aOR) and 95% confidence interval (95% CI) were calculated to identify variables independently associated with a severe outcome. Of the 645 patients with documented information on smoking habits, 62.6% were never-smokers, 32.1% ex-smokers, and 5.3% active smokers. Past tobacco use was independently associated with an increased risk of severe outcome (aOR: 1.71; 95% CI: 1.12-2.63), whereas a nonsignificant protective trend was found for active smoking. The results suggest that past smoking is associated with enhanced risk of progressing toward severe COVID-19 disease in hospitalized patients., (© 2021 Wiley Periodicals LLC.)

The aim of this study was to describe the proportion of multidrug-resistant microorganisms (MDROs) involved in ventilator-associated pneumonia (VAP) as the first hospital-acquired infection in 536 adults with restricted risk factors for MDRO-related infection. We found a significant decrease in the percentage of MDROs involved in VAP between 2003 and 2016 and this percentage increased when VAP occurred after day 10., (Copyright © 2021 The Authors.

Background: Hospital-acquired influenza potentially leads to significant morbidity and mortality in already vulnerable patients, but its overall burden is not fully understood. We undertook this study to estimate the incidence and trends of hospital-acquired laboratory-confirmed influenza among adults, and to compare clinical characteristics between hospital-acquired and community-acquired influenza cases., Methods: This was a prospective surveillance study over 11 years of adults with influenza-like-illness (ILI) hospitalized in surgery, medicine and geriatric wards in a tertiary acute-care hospital in Lyon, France. Nasal swabs were systematically collected from those with ILI and tested for influenza by reverse transcriptase-polymerase chain reaction at the national influenza reference laboratory (Lyon, France)., Results: Influenza was laboratory confirmed at a rate of 1 in 13 patients who developed ILI during their hospitalization. Having an underlying disease was an important characteristic of hospital-acquired ILI cases. Cardiovascular disease was the most frequent underlying condition in both influenza-positive and influenza-negative patients. Complications were more frequent for influenza-positive than influenza-negative patients. The influenza incidence rate was highest in the geriatric ward and increased over the study period., Conclusions: Hospital-acquired influenza poses a significant risk to already vulnerable patients. Longitudinal surveillance data are essential to support better recognition and monitoring of viral infections in hospitals., (Copyright © 2020 Association for Professionals in Infection Control and Epidemiology, Inc.
