Introduction: Survivors of severe Coronavirus Disease-2019 (COVID-19) pneumonia may experience Exercise-Induced Desaturation (EID), which can remain undiagnosed at discharge, as most exhibit normal resting Arterial Blood Gases (ABGs). This undiagnosed condition may lead to unexpected hospital readmissions, causing additional burden to the health system. However, the prevalence of EID among this population, especially in developing countries, is not well documented. Aim: To estimate the prevalence of EID among survivors of severe COVID-19 pneumonia and to explore the predictive role of Lung Ultrasound Scan (LUS) in detecting EID. Materials and Methods: This hospital-based, observational, cross-sectional study was conducted at the Institute of Chest Diseases in Kozhikode, Kerala, India from October 2021 to September 2022. It involved 153 COVID-19 patients aged 18 years and above who had recovered from severe pneumonia, were otherwise fit for hospital discharge, and had normal resting ABGs. The study examined the prevalence of EID using the 6-Minute Walk Test (6MWT). Additionally, it investigated the predictive ability of a LUS for EID. A LUS was performed on all patients and scoring was conducted according to the established protocol. Results: The mean age of the study subjects was 53.50±14.13 years, with 119 (77.8%) being male. During the 6MWT, 96 patients (62.7%) showed significant desaturation. A total of 83 (95.4%) subjects in the desaturated group required Non-Invasive Ventilation (NIV) compared to 4 (4.6%) in the non-desaturated group (p<0.001). All 24 (100%) subjects in the desaturated group required Invasive Mechanical Ventilation (IMV), while none in the non-desaturated group did. The mean Length Of Stay (LOS) in the hospital was 35.50±13.35 days for the desaturated group, compared to 23.32±16.25 days for the non-desaturated group (p<0.001). The LUS score was significantly higher in the desaturated group (16.61±5.92) than in the non-desaturated group (5.54±4.62). The Receiver Operating Characteristic (ROC) curve for the LUS score indicated a cut-off value of 8.5 for identifying significant EID. Conclusion: Survivors of COVID-19 who recovered from Acute Respiratory Failure (ARF) and have normal resting ABGs may still have significant EID. A protocol-based LUS score can potentially identify individuals at risk for EID. [ABSTRACT FROM AUTHOR]

Medical Thoracoscopy (MT) is commonly performed by respiratory physicians for diagnostic as well as therapeutic purposes. The aim of the study was to provide evidence-based information regarding all aspects of MT, both as a diagnostic tool and therapeutic aid for pulmonologists across India. The consensus-based guidelines were formulated based on a multistep process using a set of 31 questions. A systematic search of published randomized controlled clinical trials, open labelled studies, case reports and guidelines from electronic databases, like PubMed, EmBase and Cochrane, was performed. The modified grade system was used (1, 2, 3 or usual practice point) to classify the quality of available evidence. Then, a multitude of factors were taken into account, such as volume of evidence, applicability and practicality for implementation to the target population and then strength of recommendation was finalized. MT helps to improve diagnosis and patient management, with reduced risk of post procedure complications. Trainees should perform at least 20 medical thoracoscopy procedures. The diagnostic yield of both rigid and semirigid techniques is comparable. Sterile-graded talc is the ideal agent for chemical pleurodesis. The consensus statement will help pulmonologists to adopt best evidence-based practices during MT for diagnostic and therapeutic purposes. [ABSTRACT FROM AUTHOR]

Background: Coronavirus disease 2019 (COVID-19) virus has caused widespread Acute Respiratory Disease globally since 2020. Patients with evidence of lower respiratory illness either clinically or radiologically had moderate-to-severe illness. COVID respiratory and nonrespiratory symptoms (psychological and cognitive) noticed after 4–8 weeks of primary disease were called long COVID syndrome. Survivors of moderate-to-severe disease had a poor quality of life. The main objective of this retrospective study was to assess the role of outpatient pulmonary rehabilitation (PR) done in moderate-severe COVID-19 survivors who had symptoms after 4–8 weeks at Shaivam Lung Rehabilitation Centre, Ahmedabad. Methods: We analyzed the impact of PR on 30 patients' post-COVID-19 who were willing to participate during the ongoing pandemic. It was an outpatient 6–8 weeks of program designed to target respiratory and general muscle training, relaxation technique, nutritional counseling, occupational and psychological support. Patients were tested with of combination of self-assessment quality of life scale (adapted from short form 36 questionnaire), muscle training, dyspnea scale, and physical assessment. The standard objective assessment included oxygenation index (SpO2/FiO2 ratio), 6 min walk distance (6 MWD), Modified Medical Research Council (MMRC) score, manual muscle testing (MMT) along with pulmonary function testing. All these subjective and objective variables were tested pre- and post-PR program to assess the impact on defined parameters. Results: From December 2020 to March 2022, we studied the impact of PR on 30 out of 55 patients fitting into the inclusion criteria. Significant benefit was noted in subjective Short Form 36 (SF 36) score and objective (6 MWD, MMRC, oxygenation, MMT) quality of life post-PR program (P < 0.001). Improvement in spirometry was not statistically significant, indicating structural chronicity of COVID pulmonary fibrosis. Conclusion: PR is safe, effective, and feasible on an outpatient basis in COVID-19 survivors of illness with poor quality of life. Further research is required to prove its widespread benefit in such patients. [ABSTRACT FROM AUTHOR]

India experienced its sixth Nipah virus (NiV) outbreak in September 2023 in the Kozhikode district of Kerala state. The NiV is primarily transmitted by spillover events from infected bats followed by human‐to‐human transmission. The clinical specimens were screened using real‐time RT‐PCR, and positive specimens were further characterized using next‐generation sequencing. We describe here an in‐depth clinical presentation and management of NiV‐confirmed cases and outbreak containment activities. The current outbreak reported a total of six cases with two deaths, with a case fatality ratio of 33.33%. The cases had a mixed presentation of acute respiratory distress syndrome and encephalitis syndrome. Fever was a persistent presentation in all the cases. The Nipah viral RNA was detected in clinical specimens until the post‐onset day of illness (POD) 14, with viral load in the range of 1.7–3.3 × 104 viral RNA copies/mL. The genomic analysis showed that the sequences from the current outbreak clustered into the Indian clade similar to the 2018 and 2019 outbreaks. This study highlights the vigilance of the health system to detect and effectively manage the clustering of cases with clinical presentations similar to NiV, which led to early detection and containment activities.

Background: Prone position ventilation (PPV) causes improvement in oxygenation, nevertheless, mortality in severe acute respiratory distress syndrome (ARDS) remains high. The changes in the driving pressure (DP) and its role in predicting mortality in moderate to severe ARDS patients receiving PPV is unexplored. Methods: A prospective observational study, conducted between September 2020 and February 2023 on moderate-severe ARDS patients requiring PPV. The values of DP and oxygenation (ratio of partial pressure of arterial oxygen to fraction of inspired oxygen [PaO2/FiO2]) before, during, and after PPV were recorded. The aim was to compare the DP and oxygenation before, during and after PPV sessions among moderatesevere ARDS patients, and determine the best predictor of mortality. Results: Total of 52 patients were included; 28-day mortality was 57%. Among the survivors, DP prior to PPV as compared to post-PPV session reduced significantly, from 16.36 ± 2.57 cmH2O to 13.91 ± 1.74 cmH2O (p-value < 0.001), whereas DP did not reduce in the non-survivors (19.43 ± 3.16 to 19.70 ± 3.15 cmH2O (p-value = 0.318)]. Significant improvement in PaO2/FiO2 before PPV to post-PPV among both the survivors [92.75 [67.5-117.75]) to [205.50 (116.25-244.50)], (p-value < 0.001) and also among the non-survivors [87.90 (67.75-100.75)] to [112 (88.00-146.50)], (p-value < 0.001) was noted. Logistic regression analysis showed DP after PPV session as best predictor of mortality (p-value = 0.044) and its AUROC to predict mortality was 0.939, cut-off ≥16 cmH2O, 90% sensitivity, 82% specificity. The Kaplan--Meier curve of DP after PPV ≥16 cmH2O and <16 cmH2O was significant (Log-rank Mantel-Cox p-value < 0.001). Conclusion: Prone position ventilation-induced decrease in DP is prognostic marker of survival than the increase in PaO2/FiO2. There is a primacy of DP, rather than oxygenation, in predicting mortality in moderate-severe ARDS. Post-PPV session DP ≥16 cmH2O was an independent predictor of mortality. [ABSTRACT FROM AUTHOR]

Background: Scrub typhus, caused by Orientia tsutsugamushi, is an acute febrile illness with symptoms such as fever, chills, and organ failure. The similar clinical presentation in other common diseases such as malaria, dengue fever, and typhoid fever creates difficulty and delay in the clinical diagnosis of scrub typhus. This delay may increase the risk of scrub typhus complications. In India, it is a public health issue with a paucity of data. Aims and Objectives: This study aims to evaluate the clinical characteristics, outcomes, and prognostic factors of patients with scrub typhus. Materials and Methods: This institutional-based observational, cross-sectional study was conducted among consecutively selected 154 adult patients suffering from scrub typhus at a Medical College Hospital situated in the southern part of West Bengal, India. All data were collected according to a pre-designed proforma. At the end of the study, results were analyzed statistically. Results: Younger, females, and homemakers are more susceptible to scrub typhus, mostly in the post-monsoon season from July to November. The incidence of scrub typhus complications is high in the southern part of West Bengal. The case fatality rate of scrub typhus is 6.5%. Male sex, pre-hospitalization duration of illness more than 7 days, presence of diabetes mellitus, serum creatinine (Scr) more than 1.5 mg/dL, serum bilirubin more than 3 mg/dL, systolic blood pressure below 90 mmHg, altered sensorium, and acute respiratory distress syndrome were associated with poor prognosis. Conclusion: A high degree of clinical suspicion is required for the early diagnosis of scrub typhus and the factors associated with poor prognosis must be considered to reduce morbidity and mortality.

In the Nidovirales order of the Coronaviridae family, where the coronavirus (crown‐like spikes on the surface of the virus) causing severe infections like acute lung injury and acute respiratory distress syndrome. The contagion of this virus categorized as severed, which even causes severe damages to human life to harmless such as a common cold. In this manuscript, we discussed the SARS‐CoV‐2 virus into a system of equations to examine the existence and uniqueness results with the Atangana–Baleanu derivative by using a fixed‐point method. Later, we designed a system where we generate numerical results to predict the outcome of virus spreadings all over India. [ABSTRACT FROM AUTHOR]

Background: Ventilator‑associated pneumonia (VAP) in acute respiratory distress syndrome patients is expected in the setting of prolonged mechanical ventilation due to abridged immunity and dysregulation of the microorganisms inhabiting the oral cavity. We conducted this study to identify the spectrum of microorganisms causing VAP in patients admitted to the medicine intensive care unit (MICU) and their antibiotic susceptibility patterns. Materials and Methods: We conducted a retrospective cross‑sectional laboratory‑based study from January 2021 to April 2021. Our cohort included patients with respiratory distress who were admitted to the MICU. We observed the incidence of VAP and the risk factors responsible for multidrug resistance (MDR) microorganisms in the MICU, along with 250‑day survival in the existence of specific comorbidities along with VAP. Results: Clinical charts of patients (n = 366) admitted to the MICU between January 2021 and April 2021 were used. The mean age of patients admitted to MICU was 57.3 ± 18.7 years with a male predominance (n = 252, 68.8%). VAP was diagnosed in 69.1% (n = 253) of patients, and the most common microorganism in our cohort was Klebsiella pneumoniae (n = 78, 30.8%), followed by Acinetobacter spp. (n = 77, 30.4%). None of the K. pneumoniae isolates (n = 0/78) and only a minority of Acinetobacter spp. (n = 4/77, 5.2%) and Pseudomonas aeruginosa isolates(n = 8/54, 14.8%) were susceptible to fluoroquinolones. A higher proportion of K. pneumoniae (n = 1/78, 1.3%), Acinetobacter spp. (n = 2/77, 2.6%), and P. aeruginosa isolates (n = 9/54, 16.7%) were susceptible to aminoglycosides. The incidence rate of MDR microorganisms among the 253 patients diagnosed with VAP was 92.8% (n = 219/253). Conclusion: There is a high prevalence of multidrug resistance (MDR) isolates among those causing VAP in the MICU setting. Knowing the broad spectrum of causative pathogens and their susceptibility to various antibiotics may guide the physician in judicious and appropriate use of antibiotics for treatment.

Background Malaria is a significant cause of morbidity and mortality in adults and children. Plasmodium falciparum is the primary cause of severe malaria, but recently Plasmodium vivax is also recognized to cause severe malaria-associated morbidity and mortality. The study focuses on determining the mortality related to severity parameters in individuals under 12 years and their critical presentation in P.vivax malaria-infected children. Methods A prospective cross-sectional hospital-based study was conducted at Safdarjung Hospital, New Delhi, and ICMR-NIMR, New Delhi. All clinically suspected cases were admitted for screening. Exclusion criteria (rapid malaria antigen test, microscopy and medication history) were applied to all the admitted patients (n  = 221) to obtain P.vivax patients only. Patients aged ≤ 12 years were included in the study. DNA was extracted from dried blood spots and amplified by nested PCR, followed by visualization on gel electrophoresis. Result A total of 221 clinically suspected cases of malaria were screened for P.vivax. After implementing various exclusion criteria, 45/221 cases were enrolled for the study, among which 44.4% (20/45) of children had the symptoms of severe malaria in terms of cerebral malaria, thrombocytopenia, anemia, pancytopenia, acute respiratory distress syndrome and hemophagocytic lymphohistiocytosis. Conclusion Plasmodium vivax mono-infection can cause severe manifestation and must be treated as P.falciparum without any delay because it may lead to increased morbidity and mortality. A changing trend in clinical symptoms has shown in P.vivax which was an earlier phenomenon of P.falciparum. [ABSTRACT FROM AUTHOR]

Filariasis, an affliction caused by thread-like filarial worms, poses a formidable health challenge in India, with diverse regional endemicities. It manifests in two distinct forms: lymphatic and extralymphatic. The former induces agonising limb swelling, while the latter, often overlooked due to its atypical presentation, can affect various organs. Here we, present a noteworthy case involving a 25-year-old woman who succumbed to septic shock, displaying Multiple Organ Dysfunction Syndrome (MODS). The patient exhibited bicytopaenia, leukocytosis, and progressively deteriorating liver and kidney functions, culminating in Acute Respiratory Distress Syndrome (ARDS). Postmortem examinations, conducted with proper consent, revealed sheathed microfilaria in liver and bone marrow tissues. This rare multisystem involvement in filariasis, leading to a fulminant course, raises questions about potential immunosuppression triggered by disseminated filarial dissemination. The hypothesis centres on the notion that the systemic spread of filaria might underlie the severe and rapid deterioration observed in this unique case, shedding light on the intricate dynamics of this parasitic disease and its implications for immune function.

Background: Assisted reproductive technologies have been adopted widely in India with fewer incidences of complications. However, various increased risks including gestational diabetes, hypertension, and prematurity have been seen. Aim: The present clinical study was aimed at analyzing in-vitro fertilization (IVF) pregnancies and associated risk factors and major complications associated with IVF pregnancies. Methods: In 310 females undergoing IVF, the techniques, associated risk factors, and IVF-related complications were studied. The data gathered were analyzed statistically and results were formulated. Results: The study results showed that higher chances of twin pregnancy were associated with embryo transfer using 2 embryos. No significant association was seen in several pregnancies and gestational diabetes or gestational hypertension with p<0.05. The study results showed no significant association between gestational age gestational diabetes and gestational hypertension with p>0.05. Also, no significant correlation was seen in the gestational age and etiology of infertility with p=0.66. Among 68 preterm infants, 18 subjects reported ARDS (acute respiratory distress syndrome). Conclusion: Considering its limitations, the present study concludes that embryo numbers are correlated with multiple pregnancies. In older females, gestational hypertension is commonly seen, whereas, twin pregnancies are more common in younger females undergoing in-vitro fertilization pregnancies. A higher incidence of premature deliveries is seen in IVF pregnancies with no difference in the age of the females. [ABSTRACT FROM AUTHOR]

Human retro‑viral disease and the myriad opportunistic infections associated with it continue to pose a diagnostic challenge to clinicians. Disseminated Kaposi sarcoma (KS) and KS‑associated immune reconstitution inflammatory syndrome (IRIS) are entities that can be associated with adverse clinical outcomes unless recognized early by the treating physician. We present the case of a 36‑year‑old homosexual HIV‑positive male who presented with unusual symptoms of KS and KS IRIS with lower gastrointestinal bleeding and respiratory distress devoid of any cutaneous manifestations.

Many drugs were recommended as antiviral agents for infection control and effective therapy to reduce the mortality rate for COVID-19 patients. Hydroxychloroquine (HCQ), an antimalarial drug, has been controversially recommended for prophylactic use in many countries, including India, to control SARS-CoV-2 infections. We have explored the effect of prophylactic HCQ from the cells of bronchoalveolar lavage fluids from COVID-19-induced acute respiratory distress syndrome patients to determine the level of infection and ultrastructural alterations in the ciliated epithelium, type II pneumocytes, alveolar macrophages, neutrophils, and enucleated granulocytes. Ultrastructural investigation of ciliated epithelium and type II pneumocytes showed lesser infections and cellular impairment in the prophylactic HCQ+ group than HCQ− group. However, macrophages and neutrophils displayed similar infection and ultrastructural alterations in both patient groups. The enucleated fragments of granulocytes showed phagocytosis of the matured virus in HCQ+ groups. The present report unveils the ultrastructural proof to complement the paradox regarding the role of prophylactic HCQ in COVID-19 patients. [ABSTRACT FROM AUTHOR]

Background and Aim: Snakebite is an important occupational and rural hazard. It is one of the most common causes of morbidity and mortality in tropical countries. Even though snakebite is an imminently treatable condition, it is a common life-threatening emergency. We aim to study the clinical profile, complications, as length of stay in the hospital, outcome and cost of care in snakebite patients requiring admission under a medicine unit. Materials and Methods: This retrospective study was conducted carried out from May 01, 2014, to May 01, 2019. The data were extracted from the inpatient medical records, and it was analyzed. All adult patients requiring admission in medicine unit V with a diagnosis of snake envenomation were included in the study. Descriptive statistics were obtained for all variables in the study, and appropriate statistical tests were employed to ascertain the significance. Results: The cohort consists of 80 patients with 45 (56.3%) males and aged 40.06 ± 15.24 years (mean, standard deviation [SD]). The majority of the snake species identification was not available 38 (47.5%). Viper bite was the most common bite 32 (40%). The most common clinical presentation was hemotoxic 33 (31.3%) followed by neurotoxic 16 (20%). Sixty-eight (85%) patients were treated outside before presentation. The median antisnake venom (ASV) given was 10 vials, and 12 (15%) patients had allergic reaction to ASV. Sixty-nine (86%) patients had cellulitis and 16 (20%) had acute kidney injury (AKI). Twenty-four (30%) patients required intensive care monitoring, 22 (27.5%) required mechanical ventilation, and 7 (8.8%) required hemodialysis. The mean ± SD duration of hospital stay was 5.56 ± 3.76 days. The median direct cost was Rs. 19,714.5 and cost of medicine was Rs. 10,798. The mortality in this cohort was 4 (5%). Conclusion: Snakebite causes significant morbidity. Viper bite was the most common bite in our study. ASV reaction was seen in 15%, and cellulitis and AKI were the common complications. The median direct cost was Rs. 19,714.5 and cost of medicine was Rs. 10,798. The mortality in this cohort was 4 (5%). [ABSTRACT FROM AUTHOR]

Introduction: Most critically ill COVID-19 patients have bronchitis, pneumonia, and acute respiratory distress syndrome (ARDS) due to excessive inflammatory conditions. Corticosteroids have largely been prescribed for the management of inflammation in these patients. However, long-term use of corticosteroids in patients with comorbidities such as metabolic, cardiovascular, and other inflammatory disorders is ideally not recommended due to safety issues. A potential and safer anti-inflammatory therapy is therefore the need of the hour. Withania somnifera (WS), a well-known herbal medicine used during the pandemic in India to prevent SARS-CoV2 infection, also possesses antiinflammatory properties. Methods: In the present study, we, therefore, evaluated the effect of the aqueous extract of the roots of W. somnifera in the cell-based assays and in the experimental animal models of LPS-induced inflammation. Results: In the NCI-H460, A549 cells and human peripheral blood mononuclear cells (PBMCs) pre-treatment with W. somnifera reduced the LPS-induced expression of the pro-inflammatory cytokines. In addition, W. somnifera extract also showed potent anti-inflammatory activity in the lung tissues of BALB/c mice challenged intranasally with LPS. We observed a marked reduction in the neutrophil counts in the broncho-alveolar lavage (BAL) fluid, inflammatory cytokines, and fibrosis in the mice lungs pre-treated with W. somnifera. Results obtained thus suggest the potential utility of W. somnifera extract in reducing airway inflammation and recommend the clinical evaluation of W. somnifera extract in COVID-19 patients with a high propensity for lung inflammation.

Background: Initial reports from Wuhan (China) suggested poor outcomes for severe COVID-19 patients treated with Extracorporeal Membrane Oxygenation (ECMO). Extracorporeal Life Support Organization (ELSO) interim 2019 guidelines also recommended using ECMO only when all conventional therapies are exhausted. However, later studies showed that delayed ECMO initiation may lead to longer ECMO runs, offsetting any benefit from resource conservation by delaying the initiation. Hence, this study was intended to analyze the sociodemographic characteristics, type of ECMO, and complications of its outcome in the Indian scenario. Materials and methods: Demographic and patient clinical outcome data of all the patients of severe ARDS due to COVID-19 being treated with ECMO from 1st June 2020 to 31st May 2021 at Medica Super-specialty Hospital (Kolkata, India), were retrospectively compiled and analyzed. Results: Total number of patients treated was 79 with 10% female representation. The mean age was 43 ± 3.2 years and the mean body mass index 37 ± 4.3. Fifty percent of the patient survived. The mean duration of the ECMO run was 17 ± 5.2 days. Sepsis (65%) was the commonest complication observed followed by acute kidney injury (39%). Conclusion: This study provides significant insight into the outcomes of patients of COVID-19 treated by ECMO in the Indian scenario. Mortality rates of COVID-19 patients on ECMO were comparable to the non-COVID-19 patients, although the ECMO run time was relatively longer. Our study concluded that ECMO should be considered as a treatment option in appropriate COVID-19 cases. However, if the capacity diminishes in a pandemic situation, ECMO consideration should be based on more stringent criteria. [ABSTRACT FROM AUTHOR]

Tracheostomy in COVID-19 is a debatable topic, with guidelines and recommendations evolving with every wave. Tracheostomy can help early weaning and potentially increase the availability of ICU beds. The aim of our study was to determine the outcomes of patients undergoing tracheostomy at different timings. This was an ambispective observational descriptive longitudinal study of patients confirmed to have COVID-19 by real- time reverse transcriptase polymerase chain reaction (RT-PCR) admitted in the ICU and needed intubation for mechanical ventilation and underwent tracheostomy at a tertiary referral centre. This study was over a period of two months from May to June 2021. A total of 169 patients were admitted to the ICU for COVID-19 from May to June 2021 out of which 27 patients underwent open surgical tracheostomy. Study included almost equal number of male and female patients. The most frequent comorbidities were hypertension and diabetes. The majority of patients were between 5th and 7th decades of life (59.2%; 16 patients). The common indications for tracheostomy were acute respiratory distress syndrome, failure to wean from ventilation, sedation management, difficult airway, and persistent airway oedema. Five patients (18.5%) underwent tracheostomy on day 8, the maximum number on a single day. The earliest tracheostomy was done on day 3 and the latest on day 17 with variable results. There were 6 survivors out of 27, youngest being a 27-year-old female and oldest a 60-year-old male. Our study showed that there was no association of age, sex of the patients and presence of comorbid conditions with the timing of intubation. Clinical outcome of the patients also was not affected by the any of the socio clinical variables viz. age, sex of the patient, presence of comorbid conditions and timing of intubation. Tracheostomy in COVID-19 is an aerosol generating procedure; strict recommendations and guidelines need to be followed. [ABSTRACT FROM AUTHOR]

Background & objectives: Scrub typhus is a rickettsial infection seen along the Asian-Pacific rim and imposes a considerable burden on affected people in low- and middle-income countries. The present study was aimed to determine the direct cost of hospitalization of scrub typhus and its trend over six years. Methods: This was a retrospective, observational, hospital based study of individuals admitted to the hospital, diagnosed with scrub typhus over six years, from January 2013 to December 2018. The potential out of pocket expenditure was evaluated. Results: A total of 198 patients were included in the study. The median cost of admission (adjusted to INR 2020) for the six years (2013 to 2018) was found to be ₹ 37,026 (US $ 490) [interquartile range (IQR) 22,996-64,992]. The median cost for patients admitted to the intensive care unit (ICU) was ₹ 128,046 (US $ 1695) (IQR 71,575-201,171), while the cost for patients admitted to the ward-alone was ₹ 33,232 (US $ 440) (IQR 19,609-45,373). The multivariable analysis showed that ARDS and SOFA score were the independent predictors of ICU admission. Interpretation & conclusions: Hospitalisation for scrub typhus is associated with a substantial healthcare expense. The predictors of increased cost were the presence of acute respiratory distress syndrome (ARDS), shock, increasing sequential organ failure assessment (SOFA) score and duration of hospital stay.

Background: Scrub typhus is a mite-born disease scrub. It commonly manifests as an acute febrile illness with multi-system involvement. It is regarded as a life-threatening disease in children, with serious complications usually occurring in the 2nd week of illness. Aims and Objectives: The aims of this study were to explore the clinical and laboratory profile of children with scrub typhus. Materials and Methods: All children admitted with scrub typhus over 1-year duration were enrolled in the study. The clinical, laboratory profile, and outcome were observed and analyzed. Results: A total of 47 children were diagnosed with scrub typhus, 17 (36.1%) children had clinical and laboratory evidence of meningitis. The most frequent presenting features were fever (100%), headache (82.4%), vomiting (82.4%), seizures (41.2%), and altered sensorium (70.6%). The mean duration of fever was 6.57 days, eight children (7%) had persistent fever for >14 days duration. Other complications reported were hepatitis 2 (4.3%), hepatosplenomegaly in 18 (38.3%) acute respiratory distress syndrome 2 (4.3%), and shock 31 (66%). The mean cerebrospinal fluid (CSF) protein, glucose, and cell count was 65.75±9.27 mg/dL, 45.00±7.23 mg/dL, and 65.94±52.72 cells/mm³ of CSF, respectively, with lymphocyte count of more than 96% in all cases. Most patients had lymphocytic pleocytosis and the mean lymphocyte percentage was 96.2%±4.5%. Out of all 47 patients, 45 (84.61%) patients recovered with appropriate antibiotics in both groups, while two (15.38%) patients expired in the group without meningitis. Conclusion: A high degree of suspicion and knowledge of the geographical distribution of Rickettsial diseases is crucial for its early diagnosis and favorable outcome. Scrub typhus should be considered in the differential diagnosis of aseptic meningitis. [ABSTRACT FROM AUTHOR]

Background: Coronavirus disease 2019 (COVID-19) patients with acute respiratory failure who experience delayed initiation of invasive mechanical ventilation have poor outcomes. The lack of objective measures to define the timing of intubation is an area of concern. We investigated the effect of timing of intubation based on respiratory rate-oxygenation (ROX) index on the outcomes of COVID-19 pneumonia. Methods: This was a retrospective cross-sectional study performed in a tertiary care teaching hospital in Kerala, India. Patients with COVID-19 pneumonia who were intubated were grouped into early intubation (within 12 hours of ROX index <4.88) or delayed intubation (12 hours or more hours after ROX <4.88). Results: A total of 58 patients was included in the study after exclusions. Among them, 20 patients were intubated early, and 38 patients were intubated 12 hours after ROX index <4.88. The mean age of the study population was 57±14 years, and 55.0% of the patients were male; diabetes mellitus (48.3%) and hypertension (50.0%) were the most common comorbidities. The early intubation group had 88.2% successful extubation, while only 11.8% of the delayed group had successful extubation (P<0.001). Survival was also significantly more frequent in the early intubation group. Conclusions: Early intubation within 12 hours of ROX index <4.88 was associated with improved extubation and survival in patients with COVID-19 pneumonia. [ABSTRACT FROM AUTHOR]

Introduction: It is known that around one third of Coronavirus Disease-2019 (COVID-19) patients develop severe pulmonary complications and acute respiratory distress syndrome, leading to long-term impairments in Pulmonary Function Test (PFT) and physical performance. Due to deteriorating health status of the COVID-19 survivors after their recovery, rehabilitation is must. Aim: To evaluate the effect of soft tissue manual technique and breathing exercises on PFT, chest expansion and functional status in Post COVID-19 Survivors. Materials and Methods: This quasi-experimental study was carried out in the Department of Cardiorespiratory Physiotherapy, MGM hospital, Aurangabad, Maharashtra, India, from November 2021 to July 2022. Total 54 subjects diagnosed with COVID-19 who required oxygen therapy and had persistent respiratory symptoms for three weeks to six months after the infection, were included. All the subjects received one week of soft tissue manual techniques which included proprioceptive neuromuscular function, muscle energy technique for recruitment of diaphragm, muscles of respiration and the ribcage. Breathing exercises were inculcated at the end of the session to ensure relaxation of the subjects. Subjects were assessed for PFT, chest expansion and post COVID-19 Functional Status Scale (PCFS) pre and post-treatment. Data were analysed through Wilcoxon signed-rank Test. Results: Amongst total 54 subjects included, 10 (18.6%) males and 44 (81.4%) females with mean age of 29.92±11.94. After one week of intervention p-value was 0.0001 for Forced Expiratory Volume (FEV1), FEV1/Forced Vital Capacity (FVC), Peak Expiratory Flow (PEF) with mean values for FEV1 at baseline was 1.91±0.51 and post-treatment was 2.45±0.34, FVC was 2.25±0.50 before the treatment whereas it was 2.73±0.36 post-treatment with p-value of 0.002, FEV1/FVC and PEF was 83.99±12.03 and 4.36±1.78 at baseline whereas, post-treatment it was 87.76±7.29 and 5.88±0.95 respectively. The p-value of 0.0001 was also similar for chest expansion. No statistically significant difference was found in post COVID-19 functional status (p-value=0.013). Conclusion: Positive changes in the ribcage's activation and integration with its muscles were seen in all of the study variables. Therefore, it is concluded that soft tissue manipulation techniques and breathing exercise improves functional status, thoracic expansion, in post COVID-19 survivors. [ABSTRACT FROM AUTHOR]

Background Dengue fever (DF) is a common viral disease, clinical manifestations of which vary from influenza-like illness (DF) to life-threatening dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS). The aim of this article was to study the clinical profile of DF in young adults. Material and Methods This was an observational study conducted in the department of medicine over a period of 2 years (January 1, 2013—December 31, 2014). Patients aged between 18 and 30 years with serology proven (nonstructural protein 1 [NS1]/dengue immunoglobulin M [IgM]) DF were included in this study. The clinical and laboratory data was recorded and analyzed. Results Out of 418 cases, the incidence of DF, DHF, and DSS was 87.32, 7.66, and 5.02%, respectively. The most common presentations were fever (99.76%) followed by vomiting (29.43%), pain abdomen (17.94%), myalgias (13.16%), petechial rash (12.92%), and bleeding (10.29%). Dengue NS1 and IgM antibodies were positive in 87.3% and 88.12% of the patients, respectively. Ascites, splenomegaly, hepatomegaly, pleural effusion, gall bladder wall edema, and pericardial effusion were present in 8.13, 6.94, 6.70, 5.98, 2.63, and 0.72% of the patients, respectively. Complications included bleeding (10.29%), acute respiratory distress syndrome (1.67%), myocarditis (1.44%), seizures (1.44%), hemarthrosis (0.24%), and encephalopathy (0.24%). The mortality rate was 3.35% with death of 14 patients. Shock, bleeding, and elevated serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase levels predicted adverse outcome. Conclusion DF can present with a plethora of clinical manifestations in endemic areas. Adverse outcome is more likely if patients have elevated SGOT levels, shock, and bleeding. Continuous seroepidemiological surveillance is essential to control outbreak and minimize morbidity and mortality. [ABSTRACT FROM AUTHOR]

The maternal mortality rate is increasing due to associated complications of labor, the severity of infection, and comorbidities. The impact of COVID-19 infection on pregnant women data is insufficient in the literature, so in the present study, we are evaluating the rate of maternal mortality due to COVID-19 infection in McGANN Teaching District Hospital a tertiary health care center. The objective: to evaluate the rate of maternal mortality due to COVID-19 infection. Materials and methods. This is a single-center retro-prospective study, which included all maternal mortalities with COVID- 19 infection admitted to the department of obstetrics and gynecology, McGANN teaching district hospital a tertiary health care center from June 2020 to October 2021. COVID-19 infected 15 pregnant women who died during hospitalization, treatment, labor, and after labor due to various complications. Data were collected from the medical record section and presented in an excel sheet and analyzed using SPSS software. Results. In the study period, maternal mortality due to COVID-19 infection was found to be more in the less than 30 years age group (73.3 %). Nearly all cases were admitted with complaints of fever (40 %), cough (53.3 %), abdominal pain (13.3 %), and breathlessness (80 %). Out of 15 maternal deaths, most of the cases are found to be primiparous (46.7 %), and the time from delivery to a death varies from 1-14 days. Nearly 66.7 % of cases had a gestational period of fewer than 36 weeks. Pulse rate, respiration rate, inflammatory markers, prothrombin time, liver enzymes, and blood glucose levels were elevated. The total protein hemoglobin and oxygen saturation percentage declined in the cases. The known co-morbidity present in the cases associated with maternal mortality was hypertension (20 %), diabetic mellitus (13.3 %), valvular heart disease (6.7 %), and pre-eclampsia (6.7 %). The most cause of death was acute respiratory distress syndrome (80 %). Conclusions. In this study the severe infection with co-morbidities showed an increased risk of severe morbidity and mortality.

Introduction: India witnessed two distinct COVID-19 waves. We evaluated the clinico-demographic profile of patients infected during first wave (FW) and second wave (SW) in a hospital in north-east India. Methodology: Patients who tested positive for severe acute respiratory syndrome-coronavirus-2 specific gene by reverse transcriptase polymerase chain reaction across FW and SW were diagnosed as COVID-19 positive. The clinico-demographic data of these positive patients were retrieved from the specimen-referral-form. Vital parameters including respiratory rate, SpO2, data on COVID-19-associated mucormycosis (CAM), COVID-19-associated acute respiratory distress syndrome (CARDS) were obtained from hospital records for inpatients. Patients were categorized based on disease severity. The data obtained in both waves were analyzed comparatively. Results: Out of a total of 119,016 samples tested, 10,164 (8.5%) were SARS-CoV-2 positive (2907 during FW, 7257 during SW). Male predominance was seen across both waves (FW: 68.4%; SW:58.4%), with more children infected during SW. Patients with travel history (24%) and contact with laboratory confirmed cases (61%) were significantly higher during SW relative to FW (10.9% and 42.1% respectively). Healthcare worker infection was higher in SW (5.3%). Symptoms like vomiting [14.8%], diarrhea [10.5%], anosmia [10.4%] and aguesia [9.4%] were more in SW. More patients developed CARDS in SW (6.7%) compared to FW (3.4%) with 85% and 70% patients expiring across FW and SW respectively. No case of CAM is documented in our study. Conclusions: This was probably the most comprehensive study from north-east India. Industrial oxygen cylinder usage may have been the source of CAM in the rest of the country. [ABSTRACT FROM AUTHOR]

Objective: The second wave of coronavirus epidemic affected India severely. We reviewed the in-hospital deaths during the second wave at a dedicated COVID hospital to better understand the clinical characteristics of patients who died during this period. Methods: Clinical charts of all patients who were admitted and died in-hospital due to COVID-19 between 1 April 2021 and 15 May 2021 were reviewed and clinical data were analysed. Results: The total number of patients admitted to hospital and the intensive care unit was 1438 and 306, respectively. The in-hospital and intensive care unit mortality was 9.3% (134 out of 1438 patients) and 37.6% (115 out of 306 patients), respectively. Septic shock with multiorgan failure was the cause of death in 56.6% of the deceased patients (n = 73) and acute respiratory distress syndrome in 35.3% (n = 47) patients. Of the deceased, 1 patient was less than 12 years old, 56.8% were between 13 and 64 years of age and 42.5% were geriatric, that is, 65 years of age or older. There were no comorbidities in 35.1% of the deceased patients. The cause of death did not vary with the age group. Conclusion: The in-hospital and intensive care unit mortality during the second wave was 9.3% and 37.6%, respectively. There was no major age group shift in the second wave as compared to the first wave. However, a significant number of patients (35.1%) did not have any comorbidity. Septic shock with multiorgan failure was the most common cause of death followed by acute respiratory distress syndrome. [ABSTRACT FROM AUTHOR]

Background: Citrobacter freundii is a common cause of neonatal intensive care unit (NICU) outbreaks, causing high morbidity and mortality as a hospital-acquired pathogen. This is the first study from our geographic region, which makes it of utmost importance for spreading awareness about this unusual pathogen amongst healthcare settings. Aim: Investigating an outbreak caused by C. freundii in the NICU of a tertiary care hospital. Settings and Design: During the month of May 2023, an outbreak of C. freundii causing neonatal septicaemia was suspected in the NICU of a tertiary care hospital in Western Uttar Pradesh. The outbreak was investigated and surveillance conducted by the hospital infection control (HIC) team, to find a source of the infection by root cause analysis (RCA), to study clinical profiles and outcomes, to determine their antimicrobial susceptibility pattern, to take corrective action preventive action (CAPA). Materials and Methods: A total of 132 blood samples were tested for blood culture and sensitivity using the BD FX40 system. Positive flagged bottles were processed for Gram stain and sub-cultured on 5% sheep blood agar and MacConkey's agar media plates. Final bacterial identification and antibiotic susceptibility were done with an automated BD-Phoenix M-50 system. Results: C. freundii with similar antimicrobial susceptibility was identified in seven neonates, contributing to a major percentage of neonatal blood culture positivity of 13.7%, out of a total positivity rate of 38.63%. The mortality rate of this outbreak was 28.57%. The HIC team investigates this outbreak for CAPA and RCA. On environmental surveillance, C. freundii was isolated from infant incubators, dressing trolleys, and laryngoscope blades of the NICU. Discussion: C. freundii association in Blood culture from critical areas patients is life-threatening 'Consociatio Vita Minabatur Procursus'. Direct access to the bloodstream causing neonatal septicaemia in a short time is a concern for its potential severity, making it as 'Periculosus Pathogen'. Laboratory automation and implementation of strict infection control strategies in critical areas can improve clinical outcomes and prevent future outbreaks. [ABSTRACT FROM AUTHOR]

Background: Advancements in the intensive care unit (ICU) have improved critically ill subjects' short-term outcomes. However, there is a need to understand the long-term outcomes of these subjects. Herein, we study the long-term outcomes and factors associated with poor outcomes in critically ill subjects with medical illnesses. Materials and methods: All subjects (≥12 years) discharged after an ICU stay of at least 48 hours were included. We evaluated the subjects at 3 and 6 months after ICU discharge. At each visit, subjects were administered the World Health Organization Quality of Life Instrument (WHO-QOL-BREF) questionnaire. The primary outcome was mortality at 6 months after ICU discharge. The key secondary outcome was quality of life (QOL) at 6 months. Results: In total, 265 subjects were admitted to the ICU, of whom 53 subjects (20%) died in the ICU, and 54 were excluded. Finally, 158 subjects were included: 10 (6.3%) subjects were lost to follow-up. The mortality at 6 months was 17.7% (28/158). Most subjects [16.5% (26/158)] died within the initial 3 months after ICU discharge. Quality of life scores were low in all the domains of WHO-QOL-BREF. About 12% (n = 14) of subjects could not perform the activity of daily living at 6 months. After adjusting for covariates, ICU-acquired weakness at the time of discharge (OR 15.12; 95% CI, 2.08-109.81, p <0.01) and requirement for home ventilation (OR 22; 95% CI, 3.1-155, p <0.01) were associated with mortality at 6 months. Conclusion: Intensive care unit survivors have a high risk of death and a poor QOL during the initial 6 months following discharge. [ABSTRACT FROM AUTHOR]

The pandemic COVID-19 has relentlessly caused havoc to human life since its outbreak in December 2019. The disease has been a challenge for all. The clinical manifestations of Covid-19 ranges from no symptoms at all to severe acute respiratory distress syndrome. Anosmia being one of the important clinical features of COVID-19 has always been overlooked by the Indian population. This formed the background for this study. Aim To identify the incidence of anosmia reported in COVID- 19 patients in India. Materials and Methods Literature search was carried out from January 2020 to March 2021 in databases like PUBMED and Google Scholar using the key words "ANOSMIA", "HYPOSMIA" and "OLFACTORY DYSFUNCTION" in conjunction with "COVID-19", "SARS-COV-2", and "CORONAVIRUS". Boolean operators were used to narrow and broaden the search. The search yielded sixteen eligible articles. Result The scrutiny of the 16 articles revealed an incidence range of anosmia from 9.2% to 82% and an average anosmia incidence rate of 30.19%. The cumulative incidence rate of anosmia in those studies where objective analysis was done is 52.2% and 16.4% for subjective analysis. Discussion The prevalence of anosmia in Indian population is found to be much lesser than that reported by European countries due to ethnicity or negligence. Objective evaluation of anosmia in COVID-19 patients increases the incidence of anosmia drastically. Hence objective evaluations such as UPIST, SNIFFING STICK test, etc. is to be promoted. This study also Emphasises the lack of common gold standard testing for olfaction like vision and hearing. [ABSTRACT FROM AUTHOR]

Introduction: The mortality from coronavirus disease 2019 (COVID-19) infection and the severity of it vary among populations. There is a dearth of research on epidemiology and clinical outcomes in central Indian populations with COVID-19. Our aim was to provide an analysis of all hospitalized mortality among patients with COVID-19 infection in a tertiary care hospital of Chhattisgarh in central India. This analysis helped us to know the severity predictors for mortality and in future will help the authorities to formulate a plan to decrease the mortality in the epidemic or uncertain ongoing pandemic. Methodology: This was a retrospective observational study using the hospital-based record of multi-disciplinary teaching hospital in Chhattisgarh, India. All COVID-19 reverse-transcriptase polymerase chain reaction-positive patients who were declared dead or died during the course of treatment from April 1, 2020 to March 31, 2021 were included in the study. In-hospital mortality was the primary outcome of interest. In secondary analysis, age and gender distribution, co-morbidity, length of stay, and the cause of death were also investigated. Results: A total of 7495 patients with a confirmed diagnosis of COVID-19 were enrolled in the study, of whom 762 (10.16%) died in the hospital with COVID-19 as the primary cause of death. The majority of the patients were more than 60 years of age (45.7%). A total of 416 (54.4%) of the deceased patients were having co-morbidity with diabetes (13.4%), hypertension (16.4%), or both (24.4%). The majority of the patients who succumbed had a hospital stay of less than a week (≤7) (68.5%). More than half of the patients (58.3%) who expired had referred and reported to the hospital in the second or third week of illness. The respiratory system involvement was the dominant contributor of death with pneumonia (78.8%) being the most common cause, followed by acute respiratory distress syndrome (62.2%). 13.6% of expired patients had multiple system involvement, and 11.2% had sepsis as well. Conclusion: Mortality in COVID-19 patients was associated with advanced age, co-morbidities such as diabetes and hypertension, and delay in hospitalization. These are high-risk groups and should be vaccinated against COVID-19 on priority. [ABSTRACT FROM AUTHOR]

Background: Data on outcomes of coronavirus disease 2019 (COVID-19) in pregnancy are scarce, although they represent a unique physiological state affecting both the mother and child. We present collated data from a tertiary care center in North India, encompassing the outcome, clinical characteristics, and management of these patients. Materials and Methods: Parturients ≥ 18 years old, with COVID-19 reverse transcriptase polymerase chain reaction positive for severe acute respiratory syndrome coronavirus 2, requiring intensive care unit (ICU) admission at a tertiary care hospital were included. Data were retrospectively collected from April 2020 to November 2021. Results: In all, 26 parturients were admitted to ICU with COVID-19. Five patients were admitted during the first wave, and all were asymptomatic. Twenty-one patients presented during the second wave (March 2021 onward), among which four were asymptomatic and 17 symptomatic (all with severe pneumonia). Three patients presented in the second trimester, all with critical disease, out of which one did not survive. Two patients had twin gestation, and others were singleton pregnancies. Seven patients (27%) were primigravida, and five patients (19.2%) had more than third pregnancy. Twenty critically ill women (77%) delivered during the hospital stay. Six patients died during the second wave, and four deaths (66.7%) were because of COVID-19 acute respiratory distress syndrome (ARDS). Conclusions: The number of admissions and mortality related to COVID-19 ARDS was higher in the second wave than in the first. We report the safe use of remdesivir and tocilizumab in our patients.

Background: Elderly population, individuals with metabolic derangements such as diabetes mellitus and obesity, and immunocompromised patients are falling prey to the severity of illness caused by the SARS-CoV-2 viral infection. India, deemed as the "Diabetes Capital of the World," has a large population vulnerable to COVID-19 infection and its complications. Aims and Objectives: This study was conducted to measure, compare, and describe the clinical and biochemical parameters of COVID-19 patients admitted to the intensive care unit, with and without diabetes mellitus, and their outcomes in terms of morbidity and mortality. Materials and Methods: A cross-sectional comparative study was conducted on 146 hospitalized patients with COVID-19 disease confirmed with reverse transcription polymerase chain reaction, 66 of them categorized as diabetic and 80 as non-diabetic. Details of socio-demographic variables, medical history, and comorbidities of the patients were collected using a pre-tested and validated questionnaire. Vital signs and hematological, biochemical, and respiratory parameters were recorded and analyzed among both the groups of COVID-19 patients. Results: There were statistically significant differences in the age, sequential organ failure assessment scores at admission, SpO2, HbA1c, blood urea, creatinine, serum potassium, random blood sugar, ALT, pCO2, PaO2, acute respiratory distress syndrome (PaO2/FiO2), and the length of hospital stay between the diabetic and nondiabetic patients. Conclusion: Hospitalized patients with COVID-19 disease with diabetes mellitus have higher levels of inflammatory markers and of other predictors of severity of illness, need for admission in critical care units, and risk of in-hospital deaths compared to non-diabetic patients.

• Mucormycosis is an opportunistic angioinvasive infection with a high mortality rate. • A surge in mucormycosis cases has been observed during the second COVID-19 wave. • Diabetes mellitus, COVID-19, and hot climate increase the risk of mucormycosis. • Glycemic control and ketoacidosis prevention are key in managing mucormycosis. A surge in COVID-19-associated mucormycosis cases has been observed during the second wave of COVID-19 in summer of 2021. Most cases were reported from India. The Delta variant (B.1.617.2) was the most common variant circulating at that time. Mucormycosis is an opportunistic angioinvasive fungal infection with high morbidity and mortality. We present 10 cases of COVID-19-associated rhino-orbital and rhino-orbital-cerebral mucormycosis managed in a secondary hospital in Oman. The median time for developing mucormycosis was two weeks after COVID-19 diagnosis. All patients were newly diagnosed or already known to have poorly controlled diabetes mellitus. Five patients received corticosteroid therapy for COVID-19. Three patients had severe COVID-19 and died of severe acute respiratory distress syndrome and septic shock. Another three patients died of advanced mucormycosis and cerebral involvement. Despite aggressive medical and surgical intervention, the mortality rate was 60% (6/10). Mucormycosis is an aggressive opportunistic infection with high morbidity and mortality that requires prompt recognition and urgent intervention. Uncontrolled blood sugar, the use of corticosteroids, and immune dysfunction due to COVID-19 are all important risk factors for development of mucormycosis. Worse outcomes are associated with poor glycemic control despite aggressive medical and surgical interventions. [ABSTRACT FROM AUTHOR]

Background: The development of barotrauma in COVID-19 patients who were ventilated and admitted to the intensive treatment unit seemed to have been a problematic issue in the COVID era. This study aimed to explore the possibility of developing the barotrauma-related issues with mechanical ventilation in the cases of individuals suffering from COVID-19. Results: Out of 48 patients who developed barotrauma, 30 (62.5%) presented with pneumothorax, 22 (45.8%) with pneumomediastinum, 10 (20.8%) with subcutaneous emphysema, and 2 (4.1%) with pneumopericardium. Of those that developed barotrauma, 45 (93.7%) patients were in acute respiratory distress syndrome. In patients with and without barotrauma, significant factors were white blood cell count (p = 0.001), neutrophil percentage (p = 0.012), and lymphocyte percentage (p = 0.014). There were no statistically significant differences in CRP, procalcitonin, d-dimer test, LDH, or ferritin. Conclusions: Patients infected with COVID-19 have a high risk of barotrauma when on mechanical ventilation. As a result, the death rate in this patient group is higher. [ABSTRACT FROM AUTHOR]

The coronavirus disease-2019 (COVID-19) is caused by SARS-CoV-2, leading to acute respiratory distress syndrome (ARDS), thrombotic complications, and myocardial injury. Statins, prescribed for lipid reduction, have anti-inflammatory, anti-thrombotic, and immunomodulatory properties and are associated with reduced mortality rates in COVID-19 patients. Our goal was to investigate the beneficial effects of statins in hospitalized COVID-19 patients admitted to three multi-specialty hospitals in India from 1 June 2020, to 30 April 2021. This retrospective study included 1,626 patients, of which 524 (32.2%) were antecedent statin users among 768 patients (384 statin users, 384 non-statin users) identified with 1:1 propensity-score matching. We established a multivariable logistic regression model to identify the patients' demographics and adjust the baseline clinical and laboratory characteristics and co-morbidities. Statin users showed a lower mean of white blood cell count (7.6 x 10³/µL vs. 8.1 x 10³/µL, p < 0.01), and C-reactive protein (100 mg/L vs. 120.7 mg/L, p < 0.001 ) compared to non-statin COVID-19 patients. The same positive results followed in lipid profiles for patients on statins. Cox proportional- hazards regression models evaluated the association between statin use and mortality rate. The primary endpoint involved mortality during the hospital stay. Statin use was associated with lower odds of mortality in the propensity-matched cohort (OR 0.52, 95% CI 0.33-0.64, p < 0.001). These results support the previous evidence of the beneficial effects of statins in reducing mortality in hospitalized COVID-19 patients. [ABSTRACT FROM AUTHOR]

Objective: To determine whether high-flow nasal oxygen (HFNO) or noninvasive ventilator (NIV) can avoid invasive mechanical ventilation (IMV) in COVID-19-related acute respiratory distress syndrome (ADRS), and the outcome predictors of these modalities. Design: Multicenter retrospective study conducted in 12 ICUs in Pune, India. Patients: Patients with COVID-19 pneumonia who had PaO2/FiO2 ratio <150 and were treated with HFNO and/or NIV. Intervention: HFNO and/or NIV. Measurements: The primary outcome was to assess the need of IMV. Secondary outcomes were death at Day 28 and mortality rates in different treatment groups. Main results: Among 1,201 patients who met the inclusion criteria, 35.9% (431/1,201) were treated successfully with HFNO and/or NIV and did not require IMV. About 59.5% (714/1,201) patients needed IMV for the failure of HFNO and/or NIV. About 48.3, 61.6, and 63.6% of patients who were treated with HFNO, NIV, or both, respectively, needed IMV. The need of IMV was significantly lower in the HFNO group (p <0.001). The 28-day mortality was 44.9, 59.9, and 59.6% in the patients treated with HFNO, NIV, or both, respectively (p <0.001). On multivariate regression analysis, presence of any comorbidity, SpO2 <90%, and presence of nonrespiratory organ dysfunction were independent and significant determinants of mortality (p <0.05). Conclusions: During COVID-19 pandemic surge, HFNO and/or NIV could successfully avoid IMV in 35.5% individuals with PO2/FiO2 ratio <150. Those who needed IMV due to failure of HFNO or NIV had high (87.5%) mortality. [ABSTRACT FROM AUTHOR]

A Noval corona Virus also known as severe acute respiratory syndrome corona virus (SARSCo V-2) is a highly transmissible and pathogenic corona virus that emerged in end of 2019 in the Wuhan city of China and has caused a pandemic ofacute respiratory disease, named 'corona virus disease 2019' (COVID-19), which threatens human health and public safety. Noval corona Virus has now spread worldwide to become a global pandemic affecting over 10 Carors of people as of January 31th, 2021 and claimed the life of more than 2,231,230 people worldwide. Corona is asymptomatic for some individuals and for others it can cause symptoms ranging from flu-like to acute respiratory distress syndrome (ARDS), pneumonia and death. In this Review, we describe the current progress and human challenges of development of covid 19 vaccine. This study also includes the current status of peoples who are vaccinated till now in India and comparison with the other countries of the world in terms of peoples vaccinated. The social approval of vaccination presupposes social reliance and it possess a big problem in India. Therefore in-spite of government approval for vaccination being started it is important to be socially accepted by the peoples of India [ABSTRACT FROM AUTHOR]

Lung transplantation (LTx) has come as hope for select patients with post-COVID acute respiratory distress syndrome (ARDS). It has a different phenotype with unique challenges. We aimed to bring out our experience with and outcomes of LTx for post-COVID ARDS. This study is retrospective case series from a single center in India. All the patients with post-COVID end stage lung disease (ESLD) who underwent bilateral LTx between 1st May 2020 and 30th August 2021 were included. LTx was performed following no improvement with optimal medical management with adequate time provided for recovery. Information relating to demographics, comorbidities, pretransplant status, perioperative parameters, gross and histopathological findings of explanted lungs, posttransplant morbidity, and mortality were analyzed. This study included 23 patients. The median age of the patients in this study was 42 years and 20 participants were men (87%). The mean duration of intensive care unit stay was 15.83 ± 6.61 days. Mortality was observed among 8 participants (34.78%). Mean survival time was 34.54 weeks. Among the 8 patients who expired, the cause of death was sepsis for 6 patients (75.0%), neurologic cerebrovascular accident for 1 patient (12.5%), and cytomegalovirus for 1 patient (12.5%). All the deaths were reported in primary graft dysfunction grade 2 & 3 category. No rejections were observed on first and third month surveillance biopsies. LTx is the definitive option for survival in select patients with severe post–COVID-19–associated ESLD. This study brings out various challenges involved in such phenotypes and also observations in postoperative recovery. [ABSTRACT FROM AUTHOR]

The advent of COVID-19 waves has continued since 2020, and we are here to accept that as individuals we have to learn to combat and recover from this infection effectively by COVID appropriate behaviour of quarantine, complete schedules of vaccination, masking, hand washing and a good dietary intervention to enable good recovery. This compiled review from the working group of Nutritionist of Indian Dietetic Association (2019-2022) will serve as a ready reference for dietitians, physicians and healthcare professionals in different settings; to advise the right diet and adequate nutrition for the adult COVID patients in different stages of the infection.The key points include- in mild intensity disease, while the patient is quarantined and home bound, the emphasis is on consuming adequate nutrient dense foods supporting the immune system, as well as providing adequate hydration. The role of traditional practices and immune boosting nutrients will also help in supporting the mildly affected patient. In case of moderate illness, the demand consequent to running fever and cough needs to be met. The needs of the elderly population and patients with co-morbidities would be very specific and critical, and that needs to be thoroughly monitored. The management of a patient with critical illness, needing intensive care support, will need customized parenteral and enteral nutrition support. The dietary specifications in case of co-morbidities, for those needing ventilator support and ECHMO have been enumerated. This paper clearly brings out the need for an individualized nutrition support delivered by a qualified Nutritionist as a part of health care team in each of the stages of the COVID-19 infection, and is a strong recommendation.

Novel coronavirus pneumonia (COVID-19) is a respiratory infection caused by infecting lungs and respiratory pathways which has rapidly spread to 216 countries. It is causing serious harm to the world's entire population and a huge social burden, which can spread mainly by droplets produced during coughing and sneezing from animal to animal or human to human. There were no drugs or vaccines available as of May 2020. Though the severity and infectious behavior and mortality rate of COVID-19 led to the discovery of various vaccines and drugs that are available to control COVID-19 pandemic. India has two vaccines: Covishield and Covaxin approved by the Government of India on 2nd January 2021. Of this sudden and lethal disease, the traditional Indian siddha medicine was proficient as an alternative source, in performing differentiation with fewer side effects and better ability to prevent and control. In this article, we have comprehensively analyzed the case study and the efficacy of Indian Siddha medicine Kabasura Kudineer chooranam. Naturally occurring Indian Siddha medicinal (Kabasura Kudineer chooranam) compounds and its treatment as prevention measures so as to provide strategy and suggestions for the disease COVID-19 are discussed.

Background: Scrub typhus is a reemerging zoonosis, which presents as acute febrile illness. Very few paediatric prospective studies on this disease are reported from Eastern India. This prospective observational study was carried out to study the clinical presentation, diagnosis, complications and immediate outcome of Scrub typhus in paediatric population in a tertiary care hospital from Eastern India. Material and Methods: Totally 209 cases between 1 month and 18 years of age were included. Clinical manifestations, laboratory parameters and immediate outcome of all patients were recorded. All the data were collected and plotted in Microsoft Excel master chart. Continuous data were presented as mean ± standard deviation (SD) and categorical data as frequency and percentage. All the data analysis was performed using statistical software IBM Statistical Package for the Social Sciences (SPSS) version 20.0. Results: Highest number of cases (41.1%) were found between 1 year and 5 years age group. Fever was the presenting complaint in all cases. Other common symptoms were cough (34%), pain abdomen (23.4%), vomiting (23%), seizure (11.5%) and altered sensorium (9.6%). Hepatomegaly was found in 56.5% and splenomegaly in 39.7% cases. Eschar was found in 27.3% cases. C-reactive protein was elevated (>10 mg/L) in 93.3% children. Other complications were pneumonitis (20.6%), meningoencephalitis (12.4%), septic shock (8.6%), acute respiratory distress syndrome (5.7%), myocarditis (4.8%) and acute kidney injury (4.3%). Mortality was low (1%). Conclusion: Scrub typhus is not uncommon in paediatric population and it must be considered as a close differential diagnosis of any acute febrile illness even when classical clinical presentations are not found. Early treatment results in favourable outcome. [ABSTRACT FROM AUTHOR]

Background & objectives: As severe COVID-19 and mortality are not common in children, there is a scarcity of data regarding the cause of mortality in children infected with SARS-CoV-2. This study was aimed to describe the all-cause mortality and COVID-19 death (disease-specific mortality) in children with SARS-CoV-2 infection admitted to a paediatric COVID facility in a tertiary care centre. Methods: Data with respect to clinical, epidemiological profile and causes of death in non-survivors (0-12 yr old) of SARS-CoV-2 infection admitted to a dedicated tertiary care COVID hospital in north India between April 2020 and June 2021 were retrieved and analyzed retrospectively. Results: A total of 475 SARS-CoV-2–positive children were admitted during the study period, of whom 47 died [18 neonates, 14 post-neonatal infants and 15 children (1-12 yr of age)]. The all-cause mortality and COVID-19 death (disease-specific mortality) were 9.9 per cent (47 of 475) and 1.9 per cent (9 of 475), respectively. Underlying comorbidities were present in 35 (74.5%) children, the most common being prematurity and perinatal complications (n=11, 24%) followed by congenital heart disease (n=6, 13%). The common causes of death included septic shock in 10 (21%), COVID pneumonia/severe acute respiratory distress syndrome in nine (19%), neonatal illnesses in eight (17%), primary central nervous system disease in seven (15%) and congenital heart disease with complication in six (13%) children. Interpretation & conclusions: Our results showed a high prevalence of underlying comorbidities and a low COVID-19 death (disease-specific mortality). Our findings highlight that mortality due to COVID-19 can be overestimated if COVID-19 death and all-cause mortality in children infected with SARS-CoV-2 are not separated. Standardized recording of cause of death in children with SARS-CoV-2 infection is important. [ABSTRACT FROM AUTHOR]

Severe dengue causes more than 22,000 deaths annually worldwide. Complicated dengue has high mortality of 44–72%. Disordered immune system with capillary leak and thrombocytopenia are hallmark of complicated dengue. Intravenous immunoglobulin (IV Ig) therapy has shown to be effective in complicated dengue in pediatric age group with refractory shock, but studies in adults are lacking. Its immunoresuscitative role is not yet fully explored in critically ill patients with severe dengue. This is retrospective observational study of patients with complicated dengue fever who were administered IV Ig therapy in a tertiary care hospital of southern India from 01 Jan 2018 to 31 Dec 2019. A total of 999 patients with dengue were admitted; 754 (75.47%) were males, and 245 (24.53%) were females. A total of 402 (40.24%) patients presented with warning signs. Bleeding was seen in 121 patients (12.11%); 102 (10.21%) had shock; 29 (2.90%) had acute kidney injury and 24 (2.40%) had adult respiratory distress syndrome. Overall, four people died (mortality rate: 0.40%). IV Ig in the dose of 0.4 g/kg for 5 days was used in 13 critically ill patients where standard therapy failed, 9 patients with refractory shock (which included three with myocarditis with refractory shock), 2 with encephalitis, 2 in hemophagocytic lymphohistiocytosis. Two patients died, one with myocarditis with refractory shock and another with refractory shock. IV Ig therapy in critically ill patients with complicated dengue can be used as a rescue therapy.

Background: Acute respiratory distress syndrome (ARDS) associated with COVID-19 in children is not well described in the literature, so this study was designed to assess the severity, clinical course, different treatment measures, and outcome of this group of patients. Patients and methods: This descriptive study was performed by retrospective chart review of children admitted in pediatric intensive care unit (PICU) in the age-group of 1 month to 12 years over the period of 6 months (July--December 2020) in a tertiary care pediatric COVID facility in eastern India. Severity of ARDS, ventilator settings, oxygenation and laboratory parameters, and outcomes were documented. Predictors associated with severe ARDS were evaluated. Results: Among 128 laboratory-confirmed pediatric COVID-19 cases admitted in PICU, 18 (14%) developed ARDS, 6 (33.3%) had severe ARDS, and 3 (16.6%) succumbed to death. Outcome was measured by median hospital stay [20 days (IQR 19, 21)], PICU stay [13 days (IQR 10, 16)], and 28-day ventilator-free days [14 days (IQR 13, 22)]. Half (n = 9) of our study cohort had different comorbidities and congenital heart disease being the most common (4, 22.2%). Median positive end-expiratory pressure requirement was 10 cm H2O (9, 11) for invasively ventilated children (n = 13, 72.2%) along with peak inspiratory pressure of 24 cm H2O (20, 29) and mean airway pressure of 17 cm H2O (14, 20). Median oxygenation index was 13.3 (10.5, 18.6). Nine (69.2%) out of 13 intubated children had undergone prone ventilation. C-reactive protein (CRP) and D-dimer levels were significantly high in children with severe ARDS alongside pSOFA and lung USG score. Conclusion: Incidence of ARDS in pediatric COVID-19 though less but is not rare. Elevated CRP, D-dimer values, and high lung USG scores were associated with severe ARDS. Those who died had significant comorbidity. [ABSTRACT FROM AUTHOR]

Aim: To compare the demographic, clinical, laboratory and radiological parameters of patients with different clinical outcomes (death or discharge) and analyse them to find out the potential predictors for mortality in children hospitalised with SARS‐CoV‐2 infection. Methods: Retrospective chart review of all patients less than 18 years of age with laboratory‐confirmed SARS‐CoV‐2 infection and requiring hospital admission between 16 April 2020 and 31 October 2020. Results: Of 255 children with SARS‐CoV‐2 infection, 100 patients (median age 62.5 months, 59% males, 70% with moderate to severe disease) were hospitalised, of whom 27 died (median age 72 months, 59% males and 30% severely underweight). The subgroup with comorbidities (n = 14) was older (median age 126 months) and had longer duration of stay (median 10 days). Fever and respiratory symptoms were comparable while gastrointestinal symptoms were more common among non‐survivors. Hypoxia at admission (odds ratio (OR) 5.48, P = 0.001), multiorgan dysfunction (OR 75.42, P = 0.001), presence of acute kidney injury (OR 11.66, P = 0.001), thrombocytopenia (OR 4.40, P = 0.003) and raised serum C‐reactive protein (CRP) (OR 4.69, P = 0.02) were independently associated with mortality. The median time from hospitalisation to death was 3 days. The deceased group had significantly higher median levels of inflammatory parameters and a higher incidence of complications (myocarditis, encephalitis, acute respiratory distress syndrome and shock). Conclusions: Hypoxia at admission, involvement of three or more organ systems, presence of acute kidney injury, thrombocytopenia and raised serum C‐reactive protein were found to be independently associated with increased odds of in‐hospital mortality in children admitted with SARS‐CoV‐2 infection.

Scrub typhus is a re-emerging zoonotic rickettsial disease and is prevalent in many parts of India. Scrub typhus in Uttar Pradesh is virtually unknown but has shown emergence in recent reports. In this context, a prospective study was planned to analyze the prevalence and clinic-epidemiological parameters of scrub typhus in febrile patients present in JNMC hospital. Patients of >15 years with undiagnosed acute febrile illness of more than 5 days with or without acute respiratory failure and acute renal failure (ARF) were included in the study. Clinical profile was recorded through predesigned proforma. Blood samples were collected and serological tests were performed. PCR was performed on whole blood samples of positive patients. Total 414 patients, who were negative for other common febrile etiologies, i.e.: malaria, dengue, enteric fever were included in the study. Out of 414 patients, 112 (27%) were found positive for scrub typhus by ELISA and micro-immunofluorescence (MIF). PCR was negative in all cases. Slight male predominance (52.6%) was observed. Significant number of positive cases 90 (80.3%) were between 18-46 years of age (P value <0.05). Majority of cases appeared during winter season Respiratory involvement was significant in positive cases (P value <0.05). Among the gastro-intestinal symptoms, diarrhea and vomiting were also significant (P value <0.005). All the patients responded to the treatment. No complications and mortality was observed. Scrub typhus should be considered in undiagnosed febrile patients coming from rural and agricultural background with respiratory and gastrointestinal symptoms. Serology is reliable in the diagnosis of scrub typhus as molecular testing is costly, labor intensive and not helpful. [ABSTRACT FROM AUTHOR]

Introduction: Long-term quality of life, return to work, economic consequences following Acute Respiratory Distress Syndrome (ARDS) are not well described in India. This study was aimed to address the question. Methods: A prospective cohort study of 109 ARDS survivors were followed up for a minimum of 6 months following discharge. Quality of life was assessed using the SF-36 questionnaire. Respiratory quality was assessed using the St Georges Respiratory Questionnaire. Time to return to work was documented. Costs-direct medical, as well as indirect were documented up to 6 months. Results: At 6 months, 6/109 (5.5%) had expired. Low energy/vitality and general heath were noted in the SF-36 scores at 6 months; overall a moderate quality of life. Pulmonary function tests had mostly normalized. Six-min walk distance was 77% of predicted. Respiratory quality of life was good. It took at the median of 111 days to go back Interquartile range (55–193.5) to work with 88% of previously employed going back to work. There were no significant differences in the severity of ARDS and any of these outcomes at 6 months. The average total cost from the societal perspective was ₹ 231,450 (standard deviation 146,430-, 387,300). There was a significant difference between the 3-ARDS severity groups and costs (P < 0.01). There were no independent predictors of return to work. Conclusion: ARDS survivors have low 6-month mortality. Pulmonary physiology and exercise capacity was mostly normal. Overall, quality of life is average was moderate, while respiratory quality of life was good. Return to work was excellent, while cost of care falls under a catastrophic heath expense.

The year 2020 is characterised by the COVID-19 pandemic that has quelled more than half a million lives in recent months. We are still coping with the negative repercussions of COVID-19 pandemic in 2021, in which the 2nd wave in India resulted in a high fatality rate. Regardless of emergency vaccine approvals and subsequent meteoric global vaccination drives in some countries, hospitalisations for COVID-19 will continue to occur due to the propensity of mutation in SARS-CoV-2 virus. The immune response plays a vital role in the control and resolution of infectious diseases. However, an impaired immune response is responsible for the severity of the respiratory distress in many diseases. The severe COVID-19 infection persuaded cytokine storm that has been linked with acute respiratory distress syndrome (ARDS), culminates into vital organ failures and eventual death. Thus, safe and effective therapeutics to treat hospitalised patients remains a significant unmet clinical need. In that state, any clue of possible treatments, which save patients life, can be treasured for this time point. Many cohorts and clinical trial studies demonstrated that timely administration of immunomodulatory drugs on severe COVID-19 patients may mitigate the disease severity, hospital stay and mortality. This article addresses the severity and risk factors of hypercytokinemia in COVID-19 patients, with special emphasis on prospective immunomodulatory therapies. [ABSTRACT FROM AUTHOR]

Pneumothorax is a medical emergency and is associated with a significant increase in morbidity and mortality in newborns. It may lead to acute respiratory failure, systemic hypoperfusion, intraventricular hemorrhage (IVH), and death. There is a paucity of data from developing countries about the epidemiology of pneumothorax. This descriptive study was planned to study the clinical and epidemiological profile of hospitalized neonates with pneumothorax. In this retrospactive study neonates admitted to Neonatal Intensive Care Unit (NICU) from 1 January 2004 to 31 December 2016 were reviewed.Relevant statistical analyses were done. There were 144,166 live births and 189 inborn cases of pneumothorax; hence, the incidence was 1.3 per 1000 live births. Males outnumbered females by a ratio of 2:1. 50.1% of affected neonates were preterm, mean gestational age being 35.2 ± 3.9 weeks. The mean birth weight was 2238 ± 794 g. Overall median age at diagnosis was 21 h (IQR: 4–48 h), longer in preterm neonates compared to term. Hyaline membrane disease (HMD) was the most common underlying pulmonary disorder. Pneumothorax was drained in 89.2% of tension and only 16.3% of nontension pneumothoraces. Approximately 20% of the neonates were treated with needle aspiration alone and about 24% were treated conservatively. Mortality rate among neonates with pneumothorax was 21.6%. Statistically significant risk factors for mortality were very low birth weight (VLBW) (OR: 2.47, 1.31–4.68), tension pneumothorax (OR: 2.79, 1.05–7.4), and pulmonary hypoplasia (OR: 7.5, 2.8–20.2). Multiple attempts of needle drainage were needed in 2.5% of the cases. The neonates, both term and preterm, requiring drainage had longer duration of hospital stay when compared to those without requirement of drainage. We propose a trial of needle aspiration prior to ICD insertion and intubation which will prevent the complications related to intubation. [ABSTRACT FROM AUTHOR]

The SARS COVID-19 virus has arisen as a major hazard to mankind, posing harm to the whole world population. During the second COVID wave, mucormycosis has emerged as one of the deadliest and most devastating illnesses. Mucormycosis is strongly associated with diabetes, prolonged use of steroids, prolonged hospitalisation and immunocompromised states. Children have also been affected by this badly. Hyperbaric oxygen therapy is a non-invasive, cost-effective and painless therapy where 100% oxygen is given to patients under high atmospheric pressure in small tents or chambers. It helps in tissue regeneration and angiogenesis. Hyperbaric oxygen has proved to be effective in the treatment of oculo-rhino-cerebral mucormycosis. Various studies have proved its role in the management of mucormycosis and acute respiratory distress syndrome associated with COVID-19 infection. The advantages of hyperbaric oxygen are same in children as in adults with minimum side effects. Hyperbaric oxygen therapy can be one of the good adjunctive therapies in the management of mucormycosis. It is found to be safe in the treatment of COVID-19 infection, but data is still limited on its use and further studies are needed. This article is all about its use, its efficacy, and future perspectives in the management of mucormycosis and COVID-19 in view of the arrival of the third COVID wave in developing countries like India.

Background: The "second wave" of the COVID-19 pandemic hit India from early April 2021 to June 2021. We describe the clinical features, treatment trends, and baseline laboratory parameters of a cohort of patients with SARS-CoV-2 infection and their association with the outcome. Methods: This was a retrospective cohort study. Multivariate logistic regression models were fitted to identify clinical and biochemical predictors of developing hypoxia, deterioration during the hospital stay, and death. Results: A total of 2080 patients were included. The case fatality rate was 19.5%. Among the survivors, the median duration of hospital stay was 8 (5-11) days. Out of 853 (42.3%%) of patients who had COVID-19 acute respiratory distress syndrome at presentation, 340 (39.9%) died. Patients aged >45 years had higher odds of death as compared to the 18-44 years age group. Vaccination reduced the odds of death by 40% (odds ratio [OR] [95% confidence interval [CI]]: 0.6 [0.4-0.9], P = 0.032). Patients with hyper inflammation at baseline as suggested by leukocytosis (OR [95% CI]: 2.1 [1.5-3.1], P < 0.001), raised d-dimer >500 mg/dL (OR [95% CI]: 3.2 [2.2-4.7], P < 0.001), and raised C-reactive peptide >0.5 mg/L (OR [95% CI]: 3.7 [2.2-13], P = 0.037) had higher odds of death. Patients who were admitted in the 2nd week had lower odds and those admitted in the 3rd week had higher odds of death. Conclusion: This study shows that vaccination status and early admission during the inflammatory phase can change the course of illness of these patients. Improving vaccination rates and early admission of patients with moderate and severe COVID-19 can improve the outcomes. [ABSTRACT FROM AUTHOR]
