Coronavirus disease 2019 (COVID‐19) associated mucormycosis (CAM) was reported predominantly from India during the second wave of COVID‐19 and has a high mortality rate. The present study aims to understand the fungal community composition of the nasopharyngeal region of CAM‐infected individuals and compare it with severe COVID‐19 patients and healthy controls. The fungal community composition was decoded by analyzing the sequence homology of the internal transcribed spacer‐2–(ITS‐2) region of metagenomic DNA extracted from the upper respiratory samples. The alpha‐diversity indices were found to be significantly altered in CAM patients (p < 0.05). Interestingly, a higher abundance of Candida africana, Candida haemuloni, Starmerella floris, and Starmerella lactiscondensi was observed exclusively in CAM patients. The interindividual changes in mycobiome composition were well supported by beta‐diversity analysis (p < 0.05). The current study provides insights into the dysbiosis of the nasal mycobiome during CAM infection. In conclusion, our study shows that severe COVID‐19 and CAM are associated with alteration in mycobiome as compared to healthy controls. However, the sequential alteration in the fungal flora which ultimately leads to the development of CAM needs to be addressed by future studies. [ABSTRACT FROM AUTHOR]

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus-associated pneumonia and acute respiratory distress syndrome (ARDS) were often associated with hyperinflammation and elevation of several serum inflammatory markers but usually less than what is observed in non-coronavirus disease (COVID) ARDS. Elevated inflammatory markers such as C-reactive protein, interleukin (IL)-6, etc., are associated with severe infection. This study identified subphenotypes of COVID-19 ARDS patients by latent profile analysis in a cohort of Indian patients. Methods Data of n = 233 adult Indian patients with laboratory-confirmed SARS-CoV-2 infection admitted to a tertiary care teaching hospital were analyzed in this retrospective study. Only patients with acute respiratory failure (defined by partial pressure of oxygen/fraction of inspired oxygen ratio < 200 mm Hg) and chest X-ray showing bilateral infiltrates were included. Results The patients' mean (standard deviation) age was 53.3 (14.9) years, and 62% were male. A two subphenotypic model was formulated based on the lowest Bayesian information criterion. Neutrophil-to-lymphocyte ratio and serum IL-6 were latent variables in that model (entropy 0.91). The second phenotype (hyperinflammatory) had lower platelet count (p = 0.02), higher serum creatinine (p = 0.004), higher C-reactive protein (p = 0.001), higher ferritin (p < 0.001), and serum lactate dehydrogenase (p = 0.009). Age-adjusted hospital mortality (p = 0.007), duration of hospital stay (p < 0.001), and duration of intensive care unit stay (p < 0.001) were significantly higher in the second subphenotype. Conclusion Two distinct but overlapping subphenotypes were identified in SARS-CoV-2-associated respiratory failure. Hyperinflammatory subphenotype was associated with significantly poor short-term outcomes. [ABSTRACT FROM AUTHOR]

The association between the stiffening of barosensitive regions of central arteries and the derangements in baroreflex functions remains unexplored in COVID‐19 survivors. Fifty‐seven survivors of mild COVID‐19 (defined as presence of upper respiratory tract symptoms and/or fever without shortness of breath or hypoxia; SpO2 > 93%), with an age range of 22–66 years (27 females) participated at 3–6 months of recovering from the acute phase of RT‐PCR positive COVID‐19. Healthy volunteers whose baroreflex sensitivity (BRS) and arterial stiffness data were acquired prior to the onset of the pandemic constituted the control group. BRS was found to be significantly lower in the COVID survivor group for the systolic blood pressure‐based sequences (BRSSBP) [9.78 (7.16–17.74) ms/mmHg vs 16.5 (11.25–23.78) ms/mmHg; p = 0.0253]. The COVID survivor group showed significantly higher carotid β stiffness index [7.16 (5.75–8.18) vs 5.64 (4.34–6.96); (p = 0.0004)], and pulse wave velocity β (PWVβ) [5.67 (4.96–6.32) m/s vs 5.12 (4.37–5.41) m/s; p = 0.0002]. BRS quantified by both the sequence and spectral methods showed an inverse correlation with PWVβ in the male survivors. Impairment of BRS in the male survivors of mild COVID‐19 at 3–6 months of clinical recovery shows association with carotid artery stiffness. [ABSTRACT FROM AUTHOR]

Acanthamoeba is a rare cause of granulomatous amoebic encephalitis (GAE) associated with high mortality. There have been few case reports of Acanthamoeba meningoencephalitis worldwide. Hemophagocytic lymphohistiocytosis (HLH) is a severe hyperinflammatory condition caused by abnormally active macrophages and cytotoxic T lymphocytes; its secondary form is due to infections or malignancies. However, HLH is rather an unknown complication of GAE. We describe an unusual and previously unreported case of Acanthamoeba meningoencephalitis in a young immunocompetent female culminating in secondary HLH. [ABSTRACT FROM AUTHOR]

Background: Oxygen delivery devices with positive end-expiratory pressure (PEEP) valves have been described, but high inspiratory flows may lead to poor tolerance in tachypneic patients. Positive expiratory pressure oxygen therapy (PEP-OT) using an occlusive face mask, oxygen reservoir, and PEEP valve has not been evaluated in clinical settings. Materials and methods: In a single-arm intervention trial, patients aged 19-55 years admitted with acute respiratory illness with oxygen support were enrolled. PEP-OT trial was given with PEEP of 5 and 7 cm of water over 45 minutes. Feasibility was assessed as uninterrupted completion of the PEP-OT trial. The effects of PEP-OT on cardiopulmonary physiology and adverse effects of therapy were recorded. Results: Fifteen patients (6 males) were enrolled. Fourteen patients had pneumonia and one patient had pulmonary edema. Twelve patients (80%) completed the PEP-OT trial. There was significant improvement in respiratory rate (RR) and heart rate (HR) at the end of the 45-minute PEP-OT trial (p-values 0.048 and 0.003, respectively). There was a trend toward improved SpO2 and perceived dyspnea. None of the patients developed desaturation, shock, or air leaks. Positive expiratory pressure oxygen therapy is a feasible oxygen therapy in patients with acute hypoxia. Conclusion: Positive expiratory pressure oxygen therapy seems to be safe and has a positive impact on respiratory mechanics in parenchymal respiratory pathology. [ABSTRACT FROM AUTHOR]

Procalcitonin (PCT) is one of the best validated biomarkers in the management of sepsis. However, its prognostic utility remains poorly studied. The present study sought to assess the prognostic utility of serial PCT assessments in patients with sepsis, and to compare the prognostic predictive capability of serial measurements of PCT with conventional markers of inflammation and validated intensive care unit (ICU) severity scoring systems. We recruited consecutive patients admitted to the medical units of a tertiary care center with suspected or proven bacterial infection and sepsis. Measurement of serum PCT levels, inflammatory markers, and ICU severity scores were performed at admission and repeated every 48 hours subsequently for the duration of hospital stay. 99 patients with bacterial infection and sepsis were recruited and followed until death or discharge. Median serum PCT level was similar between survivors and non-survivors on day 1, but was significantly lower at days 3, 5 and 7 in the survivors. The analysis found Acute Physiology and Chronic Health Evaluation (APACHE IV) score on all days (1, 3, 5, and 7), PCT on days 5 and 7, and Sequential Organ Failure Assessment score at 24 hours to have good predictive accuracy for adverse patient outcome. PCT clearance on days 3 and 5 of admission was measured and demonstrated predictive accuracy comparable to day-matched APACHE IV scores. While serial levels of serum PCT in patients with sepsis are accurate in the prediction of adverse patient outcome, they do not offer any additional clinical benefit over existing severity of illness scores and may be cost prohibitive in resource-limited settings. While serial levels of serum PCT in patients with sepsis are accurate in the prediction of adverse patient outcome, they do not offer any additional clinical benefit over existing severity of illness scores and may be cost prohibitive in resource-limited settings.

Introduction: The objective of the study was to evaluate the clinical profile and outcome of patients with secondary hemophagocytic lymphohistiocytosis (HLH) in critically ill patients. Materials and methods: A prospective observational study was conducted where critically ill adult patients presenting with fever and bicytopenia were evaluated according to the HLH-2004 diagnostic criteria for the presence of secondary HLH. The underlying trigger, clinical profile, treatment, and outcome of patients with HLH were analyzed. Results: Of the 76 critically ill patients with fever and bicytopenia, 33 (43%) patients were diagnosed with HLH. The following triggers for HLH were identified: bacterial infections (23%), fungal infections (10%), viral infections (10%), parasitic infections (10%), autoimmune diseases (13%), and malignancy (8%). A total of 78% of the HLH cases received steroids, but the use of steroids was not associated with improvement in mortality. Conclusion: There is a high prevalence of HLH in patients presenting with fever and bicytopenia in critically ill adult patients. Infections were identified as the most common trigger of HLH.

Background: The epidemiology of the Coronavirus-disease associated mucormycosis (CAM) syndemic is poorly elucidated. We aimed to identify risk factors that may explain the burden of cases and help develop preventive strategies.Methods: We performed a case-control study comparing cases diagnosed with CAM and taking controls as recovered COVID 19 patients who did not develop mucormycosis. Information on comorbidities, glycemic control, and practices related to COVID-19 prevention and treatment was recorded. Multivariate regression analysis was used to identify independent predictors.Results: A total of 352 patients (152 cases and 200 controls) diagnosed with COVID-19 during April-May 2021 were included. In the CAM group, symptoms of mucormycosis began a mean of 18.9 (SD 9.1) days after onset of COVID-19, and predominantly rhino-sinus and orbital involvement was present. All, but one, CAM cases had conventional risk factors of diabetes and steroid use. On multivariable regression, increased odds of CAM were associated with the presence of diabetes (adjusted OR 3.5, 95% CI 1.1-11), use of systemic steroids (aOR 7.7, 95% CI 2.4-24.7), prolonged use of cloth and surgical masks (vs. no mask, aOR 6.9, 95%CI 1.5-33.1), and repeated nasopharyngeal swab testing during the COVID-19 illness (aOR 1.6, 95% CI 1.2-2.2). Zinc therapy was found to be protective (aOR 0.05, 95%CI 0.01-0.19). Notably, the requirement of oxygen supplementation or hospitalization did not affect the risk of CAM.Conclusion: Judicious use of steroids and stringent glycemic control are vital to preventing mucormycosis. Use of clean masks, preference for N95 masks if available, and minimizing swab testing after the diagnosis of COVID-19 may further reduce the incidence of CAM. [ABSTRACT FROM AUTHOR]

Objective: The objective was to study the sensitivity, specificity, and diagnostic accuracy of various computed tomography (CT) chest findings in diagnosing recurrence among pulmonary tuberculosis (PTB) suspects. Materials and Methods: A prospective observational study was conducted in a tertiary care hospital in New Delhi. A total of 130 suspects with a past history of treatment for PTB, who presented with any of the symptoms suggestive of recurrence were included. Sputum-positive, HIV-positive patients, pregnant females, and patients aged <18 years were excluded. Patients underwent CT chest followed by bronchoalveolar lavage (BAL). Results: A total of 62 patients were there in the final analysis. The median age of the patients with recurrent PTB was 27.5 years. Cough was the universal symptom in all these patients (>90%). Hemoptysis was the predominant symptom among patients with chronic pulmonary aspergillosis (66.6%). Necrotic mediastinal lymph nodes had good diagnostic accuracy of 88.71% with area under the curve of 0.806, P < 0.001 in diagnosing recurrent TB. BAL GeneXpert and mycobacteria growth indicator tube had good sensitivity (83.33% and 84.62%, respectively), specificity (100% for both), and excellent diagnostic accuracy (95.16% and 96.36%, respectively) for diagnosing recurrence in sputum negative and sputum scarce patient, (P < 0.001) when compared with composite reference standard. For culture-positive cases, BAL GeneXpert MTB/RIF had 100% sensitivity and 97.73% specificity in diagnosing recurrent PTB patients. Conclusion: The presence of mediastinal necrotic lymph node is the most accurate CT finding that can differentiate recurrent TB from post-TB sequelae. No other single chest CT scan finding had reliable diagnostic accuracy in comparison to microbiological tools in diagnosing recurrence among sputum negative or scarce previously treated PTB suspects.

Background: Hydroxychloroquine (HCQ) had generated considerable interest for coronavirus disease 2019 (COVID-19) prophylaxis. We conducted a prospective observational study at a tertiary care hospital in India, with dedicated COVID-19 care facilities. Objectives: Primary objective was incidence of adverse effects, secondary objective being efficacy in preventing COVID-19. Methods: Healthcare workers were recruited and grouped based on voluntary HCQ prophylaxis as per national guidelines. Side effects in HCQ group were graded in accordance with national cancer institute-common terminology criteria for adverse events (NCI-CTCAE) version 5.0. At 3–7-week follow-up, groups were compared for COVID-19 exposure, symptoms development and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RT-PCR results. Results: Among 358 participants recruited, 216 (60.3%) were males and mean age was 31.2 ± 6.6 years. Chemoprophylaxis was initiated by 258 (72%) participants. After loading dose, 7 (2.7%) reported grade 2 and 1 (0.4%) grade 3 adverse effects. Discontinuation of HCQ due to side effects was reported in 11 (4.3%) participants. Electrocardiogram was done by 50 (19.4%) participants on HCQ; no abnormalities were noted. A total of 106 (41%) among those taking and 63 (63%) among those not taking HCQ were tested for SARS-CoV-2 due to influenza-like illness or significant exposure. Among all participants, 25 (6.9%, 95% confidence interval [CI] 4.3–9.6) developed COVID-19 during the study period. In the group taking HCQ, 10 (3.9%) tested positive compared to 15 (15%) in the group not taking HCQ (P < 0.001). Odds ratio with HCQ intake was 0.34 (95% CI 0.13–0.83, P = 0.01) and the number needed to treat was 12. Conclusion: HCQ is safe at the recommended dose for pre-exposure prophylaxis of COVID-19.

This study aims to evaluate the role of cardiac enzymes N- terminal pro- brain natriuretic peptide (NT- proBNP) and cardiac troponin-I (CTnI) as predictors of outcomes in patients with sepsis. 78 cases with a diagnosis of sepsis were enrolled over a 2-year period. Baseline demographic, Acute Physiology and Chronic Health Evaluation-II (APACHE-II), Simplified Acute Physiology Score-II (SAPS- II), hematologic and biochemical parameters were noted. Serum NT-proBNP and CTnI were evaluated at 24 and 72 hours of admission along with echocardiography. Patients were prospectively followed up until death or discharge. Mean APACHE-II score was 19.8±9.6 and SAPS-I was 44.8±17.2. Survival rate in the study was 47.5% (36 of 78 patients). NT-proBNP was significantly higher in non- survivors with values over 4300 pg/mL at 24 hours and 5229 pg/mL at 72 hours associated with poor outcomes (p<0.05). CTnI was higher among non- survivors than in survivors, but the difference was not significant. APACHE-II score combined with NT-proBNP predicted a poor outcome in 51.2% cases compared with 14.6% cases with APACHE-II alone (p<0.05), while SAPS- II combined with NT-proBNP predicted a poor outcome in 53.6% cases as compared with 9.6% cases with SAPS-II alone (p<0.05). SAPS- II greater than 45 and NT-proBNP values at 72 hours were independent predictors of mortality in patients with sepsis. NT-proBNP is an independent predictor of mortality in patients with sepsis and its combination with APACHE-II and SAPS-II improves the predictive values of the scoring systems.

Background: COVID-19 infections among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-vaccinated individuals are of clinical concern, especially in those requiring hospitalization. Such real-world data on ChAdOx1 nCoV-19- and BBV152-vaccinated individuals are scarce. Hence, there is an urgent need to understand their clinical profile and outcomes. Methods: A 1:1 pair-matched study was performed among vaccinated and unvaccinated COVID-19 patients admitted between March 2021 and June 2021 at a tertiary care centre in New Delhi, India. The vaccinated group (received at least one dose of ChAdOx1 nCoV-19 or BBV152) was prospectively followed till discharge or death and matched [for age (±10 years), sex, baseline disease severity and comorbidities] with a retrospective group of unvaccinated patients admitted during the study period. Paired analysis was done to look for clinical outcomes between the two groups. Results: The study included a total of 210 patients, with 105 in each of the vaccinated and unvaccinated groups. In the vaccinated group, 47 (44.8%) and 58 (55.2%) patients had received ChAdOx1 nCoV-19 and BBV152, respectively. However, 73 patients had received one dose and 32 had received two doses of the vaccine. Disease severity was mild in 36.2%, moderate in 31.4% and severe in 32.4%. Two mortalities were reported out of 19 fully vaccinated individuals. All-cause mortality in the vaccinated group was 8.6% (9/105), which was significantly lower than the matched unvaccinated group mortality of 21.9% (23/105), p = 0.007. Vaccination increased the chances of survival (OR = 3.8, 95% CI: 1.42–10.18) compared to the unvaccinated group. Conclusion: In the second wave of the pandemic predominated by delta variant of SARS CoV-2, vaccination reduced all-cause mortality among hospitalized patients, although the results are only preliminary.

BACKGROUND: Efficacy of high-flow nasal cannula (HFNC) over noninvasive ventilation (NIV) in severe coronavirus disease 2019 (COVID-19) pneumonia is not known. We aimed to assess the incidence of invasive mechanical ventilation in patients with acute hypoxemic respiratory failure due to COVID-19 treated with either HFNC or NIV. METHODS: This was a single-center randomized controlled trial performed in the COVID-19 ICU of a tertiary care teaching hospital in New Delhi, India. One hundred and nine subjects with severe COVID-19 pneumonia presenting with acute hypoxemic respiratory failure were recruited and allocated to either HFNC (n = 55) or NIV (n = 54) arm. Primary outcome was intubation by 48 h. Secondary outcomes were improvement in oxygenation by 48 h, intubation rate at day 7, and in-hospital mortality. RESULTS: Baseline characteristics and PaO2/FIO2 ratio were similar in both the groups. Intubation rate at 48 h was similar between the groups (33% NIV vs 20% HFNC, relative risk 0.6, 95% CI 0.31-1.15, P = .12). Intubation rate at day 7 was lower in the HFNC (27.27%) compared to the NIV group (46.29%) (relative risk 0.59, 95% CI 0.35-0.99, P = .045), and this difference remained significant after adjustment for the incidence of chronic kidney disease and the arterial pH (adjusted OR 0.40, 95% CI 0.17-0.93, P = .03). Hospital mortality was similar between HFNC (29.1%) and NIV (46.2%) group (relative risk 0.6, 95% CI 0.38-1.04, P = .06). CONCLUSIONS: We were not able to demonstrate a statistically significant improvement of oxygenation parameters nor of the intubation rate at 48 h between NIV and HFNC. These findings should be further tested in a larger randomized controlled trial. [ABSTRACT FROM AUTHOR]

The World Health Organization (WHO) has declared coronavirus disease 2019 (COVID-19) as pandemic in March 2020. Currently there is no specific effective treatment for COVID-19. The major cause of death in COVID-19 is severe pneumonia leading to respiratory failure. Radiation in low doses (<100 cGy) has been known for its anti-inflammatory effect and therefore, low dose radiation therapy (LDRT) to lungs can potentially mitigate the severity of pneumonia and reduce mortality. We conducted a pilot trial to study the feasibility and clinical efficacy of LDRT to lungs in the management of patients with COVID-19. From June to Aug 2020, we enrolled 10 patients with COVID-19 having moderate to severe risk disease [National Early Warning Score (NEWS) of ≥5]. Patients were treated as per the standard COVID-19 management guidelines along with LDRT to both lungs with a dose of 70cGy in single fraction. Response assessment was done based on the clinical parameters using the NEWS. All patients completed the prescribed treatment. Nine patients had complete clinical recovery mostly within a period ranging from 3 to 7 days. One patient, who was a known hypertensive, showed clinical deterioration and died 24 days after LDRT. No patients showed the signs of acute radiation toxicity. The results of our pilot study suggest that LDRT is feasible in COVID-19 patients having moderate to severe disease. Its clinical efficacy may be tested by conducting randomized controlled trials. LDRT has shown promising results in COVID-19 pneumonia and should be researched further through randomized controlled trials. [ABSTRACT FROM AUTHOR]

Background: Pulmonary aspergilloma (PA) is a common complication seen in patients with pulmonary tuberculosis sequelae. Antifungal therapy, including oral azoles, is commonly used though only surgical resection offers curative benefit. Local administration of amphotericin B, like intracavitary instillation, has been effective in aspergilloma patients though nebulised amphotericin B (nAB) has never been formally assessed. Objective: The aim of this prospective, non‐inferior, open‐label, randomised control trial is to evaluate the efficacy and safety of nebulised amphotericin B compared to oral itraconazole therapy in the treatment of PA. Patients/Methods: Diagnosed cases of PA (n=33) were randomised into the control group receiving oral itraconazole (n=18) and intervention group receiving nebulised amphotericin B (n = 15). Response to treatment was assessed both clinically and radiologically at the end 6 months. Results and Conclusion: The number of patients showing overall improvement at the end of 6 months in the control arm(oral itraconazole) vs intervention arm(nebulised amphotericin B) was 65% (95% CI 38.3–85.8) and 67%(95% CI 38.4%–88.2%), respectively, in the intention‐to‐treat and 79% (95% CI 49.2%–95.3%), and 65% (95% CI 38.4%–88.2%), respectively, in the per‐protocol analysis. While there was no statistically significant difference between the intervention and control arm in both the analyses, non‐inferiority was shown in the per‐protocol but not in the intention‐to‐treat analysis. No major adverse events were noted in either group; however, a significant proportion of patients receiving nAB reported minor cough (40%), which, however, did not lead to discontinuation of therapy in any patients. Nebulised amphotericin B can be an effective therapeutic option for pulmonary aspergilloma patients. [ABSTRACT FROM AUTHOR]

Background The prevalence of anti-retroviral therapy (ART) failure is not uniform in India. In this study we attempted to determine the prevalence and risk factors of treatment failure among patients who were on ART for >1 y. Methods We conducted an ambispective study from 2017 to 2019 in the All India Institute of Medical Sciences, New Delhi, India. Patients and their past medical records were examined to determine clinical, immunological and virological failure. Results Among 301 enrolled patients, the majority was male (61.8%), with a mean age of 36.98±10.84 y. The prevalence of ART failure in our study was 10.63% (32/301). Clinical, immunological and virological failure rates were 1.66%, 10.63% and 5.65%, respectively. The maximum chance of failure was the tenofovir–lamivudine–nevirapine (33.3%) regimen followed by the stavudine–lamivudine–nevirapine (30.4%) regimen. Among the nucleoside reverse transcriptase inhibitors, a stavudine-based regimen had a significantly greater chance of failure (25.8%) compared with tenofovir (9.6%) and zidovudine (7.9%) regimens (p<0.005). Low baseline CD4 count and development of tuberculosis after ART initiation were significantly (p<0.05) associated with treatment failure in univariate analysis. Patients with a low peak CD4 count (adjusted odds ratio [AOR 4.26 {95% confidence interval 1.83 to 9.88}]) and who developed symptoms after ART initiation (AOR 3.77 [95% CI 1.47 to 9.69]) had significantly higher odds of treatment failure in the multivariate analysis (p<0.001). Conclusions Early identification of risk factors by regular follow-up and selection of the proper ART regimen can reduce the rate of treatment failure. [ABSTRACT FROM AUTHOR]

Objective: To study the utility of point of care ultrasound (POCUS) in the diagnosis and management of shock when performed by medicine residents. Methods: A retrospective, case-control study was carried out in the medical intensive care unit at a tertiary care hospital. Consecutive patients who had received bolus fluid for hypotension during the hospital stay were screened from the case sheets and recorded. Results: A total of 57 patients were recruited into the study. Baseline parameters were comparable in both groups. The median amount of fluid given by the physician was 1000 milliliters (500, 1500) in the inferior vena cava (IVC) group as compared with 1000 milliliters (500, 1000) in the clinical group which was similar between the groups (P =.51). The median quantity of fluid received in the first hour in the IVC group (500 milliliters; 75, 750) was significantly higher than in the clinical group (100 milliliters; 100, 125) (z = 2.98; P =.003). More improvement in heart rate (P =.0004), mean arterial pressure (MAP; P =.04), and Acute Physiology and Chronic Health Evaluation (APACHE; P =.0004) score was seen in the IVC group which was statistically significant. Conclusion: In this cohort, there was a significant increase in MAP, reduction in the APACHE II score, and heart rate in the IVC group when compared with the clinical group. [ABSTRACT FROM AUTHOR]

Objectives: Rheumatoid arthritis (RA) is a chronic disorder causing inflammation in the joints and achieving remission is often the primary goal of physicians. We evaluated the suffering from RA and assessed the need for palliative care services in these patients. Materials and Methods: This cross-sectional observational study was done in 100 adult RA cases who attended the outpatient department. The Disease Activity Score 28 (DAS28), Health Assessment Questionnaire Disability Index, depression, anxiety and stress score, Short Form 36 Health Survey and numeric rating scale were assessed. The relationship between DAS28 with the other parameters and scores was assessed using Spearman's rho correlation coefficient. Results: About 90% of patients in our study were female and majority (50%) had a moderate disease activity. The DAS28 showed a positive correlation with the degree of depression (r = 0.671, P = 0.000), anxiety (r = 0.609, P = 0.000) and stress levels (r = 0.474, P = 0.000). The patients with severe disease had a poor quality of life (QoL) [physical functioning (r = --0.737, P = 0.000); role limitation (r = --0.662, P = 0.000); emotional problem (r = --0.676, P = 0.000); energy/fatigue (r = --0.638, P = 0.000); social functioning (r = --0.658, P = 0.000); emotional well-being (r = --0.605, P = 0.000); general health (r = --0.643, P = 0.000); health change (r = --0.376, P = 0.000) and numerical rating scale score for pain (r = 0.656, P = 0.000)]. Conclusion: RA patients with high disease activity suffer from depression, anxiety, stress and poor QoL. Palliative care physicians and rheumatologists must be vested with the power to provide comprehensive care to these patients. [ABSTRACT FROM AUTHOR]

Background: despite being in the 5th month of pandemic, knowledge with respect to viral dynamics, infectivity and RT-PCR positivity continues to evolve. Aim: to analyse the SARS CoV-2 nucleic acid RT-PCR profiles in COVID-19 patients. Design: it was a retrospective, observational study conducted at COVID facilities under AIIMS, New Delhi. Methods: patients admitted with laboratory confirmed COVID-19 were eligible for enrolment. Patients with incomplete details, or only single PCR tests were excluded. Data regarding demographic details, comorbidities, treatment received and results of SARS-CoV-2 RT-PCR performed on nasopharyngeal and oropharyngeal swabs, collected at different time points, was retrieved from the hospital records. Results: a total of 298 patients were included, majority were males (75·8%) with mean age of 39·07 years (0·6–88 years). The mean duration from symptom onset to first positive RT-PCR was 4·7 days (SD 3·67), while that of symptom onset to last positive test was 17·83 days (SD 6·22). Proportions of positive RT-PCR tests were 100%, 49%, 24%, 8·7% and 20·6% in the 1st, 2nd, 3rd, 4th and >4 weeks of illness. A total of 12 symptomatic patients had prolonged positive test results even after 3 weeks of symptom onset. Age > = 60 years was associated with prolonged RT-PCR positivity (statistically significant). Conclusion: this study showed that the average period of PCR positivity is more than 2 weeks in COVID-19 patients; elderly patients have prolonged duration of RT-PCR positivity and requires further follow up.

Background: Snakebite is a common but neglected public health problem of tropical & subtropical regions worldwide. This study was conducted to look into profile, first aid measures, management strategy and outcomes of snake bite patients. Methods: This was an ambispective study conducted in the Department of Medicine & Emergency Medicine at AIIMS, New Delhi from June 2011 to May 2017 and enrolled 54 patients. In retrospective part 33 case records of snake bite patients were retrieved and in prospective part 21 patients were recruited. All relevant information including demographic parameters, first aid measures, clinical and laboratory profile and outcomes were recorded in pre made proformas. All data were analysed using IBM Stata version 13 and Microsoft Excel 2011. Results: Majority of patients were male, and the mean age was 27.6 years. Maximum numbers of bites 34 (63%) happened in the rainy season and Krait was the most common culprit species. Neurological manifestations were most common (70.4%) followed by haematological. Most common complication was ventilatory failure (78.6%), and median dose of ASV was 20 vials. Forty-nine (90.7%) patients were discharged successfully. There was significant association of sepsis and shock with non survivors of snake bite with respective P values of 0.02 and 0.007. Conclusion: Neurotoxic snake bite (70.4%) was the most common type of envenomation. Most common complication was ventilatory failure and majority of patient (90.7%) successfully discharged. Sepsis and shock were significantly associated with non survivors of snake bite. [ABSTRACT FROM AUTHOR]

Purpose Of Study: Ultrasound (US) for lumbar puncture has seen the most success in obese patients and in patients with difficult to palpate landmarks. We aimed to elucidate the advantage of the use of routine US for performing lumbar punctures over the traditional landmark method.Study Design: This was a prospective study with consecutive sampling with a sample size of convenience. Three residents were chosen to perform the lumbar punctures after a training session. Patients were assigned to either the US group or the landmark group. The outcomes studied were number of attempts at needle insertion, patient and physician anxiety, pain experienced, time to procedure, number of traumatic attempts and the difficulties faced during the procedure.Results: A total of 77 patients were included in this study, of which 36 patients (46.8%) underwent landmark-based lumbar puncture and 41 (53.2%) underwent US-guided lumbar puncture. There was no statistically significant difference between the two groups among the following characteristics: number of attempts to a successful procedure, number of traumatic punctures, procedure time, preprocedure anxiety of the participants and physicians and pain score rating of the procedure.Conclusion: There was no significant difference between the landmark method and US-guided method for performing lumbar puncture in the number of successful attempts, number of traumatic punctures, procedure time and pain during the procedure. Further studies are required to elucidate the advantage of the use of ultrasonography in subsets of the population such as the low body mass index population. [ABSTRACT FROM AUTHOR]

Coronavirus disease 2019 (COVID-19) is a febrile respiratory illness that has spread rampantly across the globe and has emerged as one of the biggest pandemics of all time. Besides the direct effects of COVID-19 on mortality, collateral impacts on diagnosis and management of acute febrile illnesses (AFI) is a matter of great concern. The overlap in presentation, shunting of available resources and infection control precautions in patients with suspected COVID-19 result in a significant delay in diagnoses and management of AFI. This review highlights the challenges in the management of acute febrile illness during COVID pandemic and possible solutions for the same. [ABSTRACT FROM AUTHOR]
