Evaluation of Loop-Mediated Isothermal Amplification Assay in Diagnosing Tuberculous Meningitis.

BACKGROUND: Resource-limited settings like India need a simple, quick, and temperature-independent point-of-care diagnostic test that can diagnose tuberculous meningitis (TBM) at the earliest. METHODS: A prospective study was carried out at a tertiary care center in North India wherein 50 subjects suspected of TBM were recruited and followed up for six months between January 2019 and December 2020. The aim was to evaluate the performance of loop-mediated isothermal amplification (TB-LAMP) in diagnosing TBM as compared to a composite reference standard (CRS), mycobacteria growth indicator tube 960 (MGIT 960) culture, and GeneXpert®. RESULTS: Out of 50 patients, 32 were TBM cases (64%), and 18 were non-TBM cases (36%). The sensitivity of TB-LAMP and GeneXpert® for TBM diagnosis against CRS was 53% (17/32) for both, and the specificity was 78% (14/18) and 89% (16/18), respectively. On comparing TB-LAMP against GeneXpert® for TBM diagnosis, the two methods had almost perfect agreement (Cohen's kappa=0.83) with statistical significance (p<0.001). CONCLUSION: The performance of TB-LAMP assay is comparable to GeneXpert® in diagnosing TBM, and it may be used as a substitute for CSF GeneXpert® in resource-limited settings.

Effect of volume of instillate on the diagnostic utility of bronchoalveolar lavage galactomannan in patients with suspected chronic pulmonary aspergillosis-A pilot study.

BACKGROUND: Bronchoalveolar lavage (BAL) galactomannan (GM) is commonly used to diagnose Aspergillus-related lung diseases. However, unlike serum GM, which is measured in undiluted blood, BAL-GM is estimated using variable aliquots and cumulative volume of instillates during bronchoscopy. OBJECTIVE: Since different studies have reported varying diagnostic accuracy and cut-offs for BAL-GM in CPA, we hypothesized that the total volume of instillate and 'order/label' of aliquots significantly affects the BAL-GM values, which was evaluated as part of this study. PATIENTS & METHODS: We obtained 250 BAL samples from 50 patients (five from each) with suspected chronic pulmonary aspergillosis. BAL fluid was collected after instilling sequential volumes of 40 mL of normal saline each for the first four labels and a fifth label was prepared by mixing 1 mL from each of the previous labels. The GM level of each label was measured by PLATELIA™ ASPERGILLUS Ag enzyme immunoassay. This study measured the discordance, level of agreement, diagnostic characteristics (sensitivity, specificity and AUROC) and best cut-offs for BAL-GM in the different aliquots of lavage fluid. RESULTS: The study population, classified into CPA (28%) and non-CPA (72%) groups, based on ERS/ESCMID criteria (excluding BAL-GM) were not different with respect to clinico-radiological characteristics. The discordance of BAL-GM positivity (using a cut-off of >1) between the serial labels for the same patient ranged between 10% and 22%, while the discordance between classification using BAL-GM positivity (using a cut-off of ≥1) and clinic-radio-microbiological classification ranged between 18% and 30%. The level of agreement for serial labels was at best fair (<0.6 for all except one 'label'). The AUROC for the serial samples ranged between 0.595 and 0.702, with the '40 mL and the 'mix' samples performing the best. The best BAL-GM cut-off also showed significant variation between serial labels of varying dilutions (Range:1.01 - 4.26). INTERPRETATION: This study highlights the variation in BAL-GM measured and the 'positivity' between different 'labels' of aliquots of BAL, with the first aliquot and the mixed sample showing the best performances for diagnosis of CPA. Future studies should attempt to 'standardise' the instilled volume for BAL-GM estimation to standardise the diagnostic yield.

Malarial Antibodies and Endemicity: Does It Affect SARS-CoV-2 Severity and Outcomes?

Background India has a disproportionately lower rate of coronavirus disease 2019 (COVID-19) severe disease and lower death rates with respect to other parts of the world. It has been proposed that malaria-endemic countries such as India are relatively protected against severe COVID-19 disease and deaths. Methods This was a cross-sectional, analytical, observational study conducted from August 2020 to July 2021 at a tertiary care COVID-19-designated center in New Delhi, India. It aimed to study the association between antimalarial antibody levels and COVID-19 disease severity and outcomes. Results One hundred forty-six patients were included in the final analysis. The mean (standard deviation {SD}) age of the study population was 44.6 (17.2) years, and there were 85 (58.2%) males. Sixty-five patients had mild disease, 14 patients had moderate disease, and 67 patients had severe disease at the time of enrolment in the study. Forty-six patients expired during the hospital stay. For the antimalarial antibody, there was a statistically significant difference between mild and moderate (p=0.018), mild and severe (p=0.016), and mild and combined moderate and severe diseases (p=0.013). However, there was no difference between the patients who survived and those who did not. Conclusion Antimalarial antibody levels may not be associated with the outcomes of COVID-19 during hospital stay. However, this study has provided some insights into the relationship between the severity and outcomes of COVID-19 and the levels of antimalarial antibodies.

Prevalence of sarcopenia and its determinants in people with type 2 diabetes: Experience from a tertiary care hospital in north India.

OBJECTIVES: Changes in skeletal muscle mass and quality are associated with type 2 Diabetes (T2D) and its complications. We evaluated the prevalence of sarcopenia in patients with T2D and its association with various anthropometric and metabolic parameters. METHODS: A total of 229 patients with T2D, ≥20-60 years, were screened for sarcopenia using handgrip strength (HGS) by dynamometer, physical performance test (by Short Physical and chair stand test), and height-adjusted appendicular skeletal muscle index (ASMI) by Dual Energy X-ray Absorptiometry (DXA) applying Asian Working Group on Sarcopenia (AWGS). Multiple logistic regressions were performed to identify the factors associated with sarcopenia. RESULTS: The mean age was 46.2 ± 7.4 years with 55% being women. The prevalence of low HGS, poor physical performance, low ASMI, possible sarcopenia, sarcopenia, and severe sarcopenia was 16.2%, 39.3%, 33%, 43%, 18.8%, and 6.1%, respectively. Age >45 years and use of >2 oral hypoglycaemic agents (OHA's) were risk factors for low HGS (OR:3.51, 95%CI = 1.5-8.3) and low ASMI (OR:2.40, 95%CI = 1.05, 5.49, p-0.04), respectively. Female sex (OR:3.3 1.8-6.1 p < 0.01), age >45 years (OR:2.12, 95% CI = 1.2-3.8 p-0.012) and liver fibrosis (OR: 2.12, 95% CI = 1.01-4.46 p-0.048) were independently associated with poor performance. No association was found with HbA1c, dyslipidaemia, albuminuria, hypertension, or duration of diabetes and sarcopenia. CONCLUSION: Sarcopenia is becoming increasingly recognized as a significant complication in younger individuals with T2D, and poor physical performance plays a vital role in its development. The prevalence of sarcopenia rises with advancing age, underscoring the importance of early intervention to address this condition.

The Utility of Galactomannan and Polymerase Chain Reaction Assays in Bronchoalveolar Lavage for Diagnosis of Chronic Pulmonary Aspergillosis.

The diagnosis of chronic pulmonary aspergillosis (CPA) is established by combined clinic-radio-microbiological criteria. Out of the different microbiological criteria, a positive serology for Aspergillus-specific IgG levels is the cornerstone of diagnosis. Alternatively, other microbiological evidence are sometimes sought viz., positive Aspergillus antigen (broncho-alveolar lavage fluid, i.e., BALF galactomannan ≥ 1.0), histopathological demonstration of the fungi following lung biopsy or resection, demonstration of hyaline septate hyphae in direct microscopy resembling Aspergillus spp. or its growth on a respiratory specimen. However, the exact roles of BALF- GM and the newer BALF-PCR have not been confirmed by studies till date. This study enrolled 210 patients with suspected CPA. Of the participants, 88 patients met the criteria for CPA, whereas 122 patients had an alternative diagnosis. The sensitivity-specificity of AsperGenius® PCR and "in-house" PCR were 52.27(36.69-67.54) %-33.78 (23.19-45.72) % and 36.36 (22.41-52.23) %-39.19 (28.04-51.23) % respectively. The sensitivity/specificity of BALF (> 1.0) and serum galactomannan (> 1.0) were 46.55% (33.34-60.13)/64.08% (54.03-73.3) and 29.82% (22.05-37.6)/86.84% (81.1-92.59) respectively. The optimal cut-off values for BALF-Galactomannan and serum galactomannan in diagnosing CPA were found to be 0.69 (sensitivity: 64%; specificity: 53%) and 0.458 (sensitivity: 67%; specificity: 64%) respectively. This results of this study suggests that Aspergillus PCR from BAL may not be a good "rule-in" test for diagnosing CPA. While the performances of GM in BAL and serum may be better than PCR, it should be best used in conjunction with other clinical, radiological, and other microbiological characteristics.

Extensive Metastatic Vascular Calcification in a Patient with Chronic Renal Failure and Tubercular Osteomyelitis as Seen on F-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

A 48-year-old male with known tubercular osteomyelitis of the left elbow and chronic renal failure presented with PTH independent hypercalcemia and underwent F-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) to look for any underlying malignancy that might be causing his hypercalcemia. The PET/CT did not reveal any malignancy, but extensive metastatic calcification of small- and medium-sized arteries was noted throughout the body with relative sparing of large vessels. Alkaline tissue such as lungs, gastric mucosa, and kidneys that are usually involved in metastatic calcification were also spared. The underlying pathology for this kind of metastatic calcification was most likely chronic granulomatous disease, which was tubercular osteomyelitis in this patient. We present the PET/CT scan images of this unusual case of metastatic vascular calcification.

Mitochondrial toxicity induced by linezolid causing lactic acidosis.

Linezolid-induced lactic acidosis is a rare, but life-threatening complication of a commonly used drug. Patients present with persistent lactic acidosis, hypoglycaemia, high central venous oxygen saturation and shock. Linezolid causes mitochondrial toxicity due to impaired oxidative phosphorylation. This is evidenced by cytoplasmic vacuolations in the myeloid and erythroid precursors of bone marrow smear as illustrated in our case. Discontinuation of the drug, administration of thiamine and haemodialysis reduces lactic acid levels.

How Indian obese population managed their lifestyle during first and second lockdown during COVID-19 pandemic? - A comparative study.

Background: People from all over the world have been affected by the COVID-19 (SARS-CoV-2) pandemic. The lockdown during the pandemic has impacted the lifestyle of most of the population. The aim of the present study is to compare the effect of COVID lockdown-1 and lockdown-2 on the lifestyle of the obese Indian population. Methods: This was a cross-sectional study conducted during the COVID-19 lockdown on obese adults. A well-structured questionnaire was developed and administered among the study population. The study was conducted in two phases (lockdown-1 and lockdown-2). A total of 390 subjects were included in the study (260 subjects in the lockdown-1 phase and 130 subjects in the lockdown-2 phase). Data on diet, sleep, stress, and physical activity were obtained and analyzed. Results: The mean age of the participants of phase-1 in the study was 41.7 ± 10.2 years and the participants of phase-2 were 44.5 ± 9.2 years. Statistically significant differences were observed between lockdown-1 and lockdown-2 in terms of monitoring of weight and other comorbid conditions, changes in the consumption of refined flour and processed foods, sugar and sugar-sweetened foods, oils and ghee, duration of physical activity, changes in the duration of sleep, and the stress levels related to COVID-19 (P < 0.001). Conclusion: The impact of the lockdowns on health was very significant and different areas of lifestyle were affected in both the lockdowns. Weight gain was reported in both phases of the lockdown. The monitoring of health parameters, eating frequency, diet, and stress levels were affected during lockdown-1, whereas during lockdown-2, sleep duration and physical activity were affected. A comprehensive lifestyle modification plan is required to be developed to avoid these effects in the future.

Indian medical student perspectives on online mode of education.

Purpose: The coronavirus pandemic has led to drastic changes in the education system globally. The medical education curriculum has also undergone a significant drift from traditional or physical classes to online classes. The study aims to explore the viewpoints of the Indian medical students toward online classes, their ramifications, and suggestions for improvement. Methods: The self-administered online questionnaire using the Google form was developed, validated, and circulated among students of All India Institute of Medical Sciences (AIIMS), New Delhi. The data of the survey were systematically analyzed by descriptive statistics. Results: A total of 223 students filled the Google form. After applying the inclusion and exclusion criteria, 171 students were finalized, and the analysis was done. The data suggested that 49.7% of the participants were facing technical glitches, poor Internet connectivity being the commonest. Eye straining (56.7%) was the major physical health hazard, whereas lack of concentration (53.8%) was the major psychological issue reported by the students. The major advantage of online classes reported was its accessibility (93%) at any time and place, whereas students also reported that the traditional learning method is more interactive and motivating (72.5%). Overall, 72.5% of the students wanted to continue both modes of education after the coronavirus disease (COVID-19) pandemic. Conclusion: As per the analysis of the results, it is concluded that, since both online and offline modes of education have advantages and disadvantages, henceforth, mixed or blended method of learning is the best form of learning medical science.

Clinical profile of ChAdOx1 nCoV-19- and BBV152-vaccinated individuals among hospitalized COVID-19 patients: a pair-matched study.

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.

Heat-induced SIRT1-mediated H4K16ac deacetylation impairs resection and SMARCAD1 recruitment to double strand breaks.

Hyperthermia inhibits DNA double-strand break (DSB) repair that utilizes homologous recombination (HR) pathway by a poorly defined mechanism(s); however, the mechanisms for this inhibition remain unclear. Here we report that hyperthermia decreases H4K16 acetylation (H4K16ac), an epigenetic modification essential for genome stability and transcription. Heat-induced reduction in H4K16ac was detected in humans, Drosophila, and yeast, indicating that this is a highly conserved response. The examination of histone deacetylase recruitment to chromatin after heat-shock identified SIRT1 as the major deacetylase subsequently enriched at gene-rich regions. Heat-induced SIRT1 recruitment was antagonized by chromatin remodeler SMARCAD1 depletion and, like hyperthermia, the depletion of the SMARCAD1 or combination of the two impaired DNA end resection and increased replication stress. Altered repair protein recruitment was associated with heat-shock-induced γ-H2AX chromatin changes and DSB repair processing. These results support a novel mechanism whereby hyperthermia impacts chromatin organization owing to H4K16ac deacetylation, negatively affecting the HR-dependent DSB repair.

Efficacy of LD Bio Aspergillus ICT Lateral Flow Assay for Serodiagnosis of Chronic Pulmonary Aspergillosis.

Background: The diagnosis of CPA relies on the detection of the IgG Aspergillus antibody, which is not freely available, especially in resource-poor settings. Point-of-care tests like LDBio Aspergillus ICT lateral flow assay, evaluated in only a few studies, have shown promising results for the diagnosis of CPA. However, no study has compared the diagnostic performances of LDBio LFA in setting of tuberculosis endemic countries and have compared it with that of IgG Aspergillus. Objectives: This study aimed to evaluate the diagnostic performances of LDBio LFA in CPA and compare it with existing the diagnostic algorithm utilising ImmunoCAP IgG Aspergillus. Methods: Serial patients presenting with respiratory symptoms (cough, haemoptysis, fever, etc.) for >4 weeks were screened for eligibility. Relevant investigations, including direct microscopy and culture of respiratory secretions, IgG Aspergillus, chest imaging, etc., were done according to existing algorithm. Serums of all patients were tested by LDBio LFA and IgG Aspergillus (ImmunoCAP Asp IgG) and their diagnostic performances were compared. Results: A total of 174 patients were included in the study with ~66.7% patients having past history of tuberculosis. A diagnosis of CPA was made in 74 (42.5%) of patients. The estimated sensitivity and specificity of LDBio LFA was 67.6% (95% CI: 55.7−78%) and 81% (95% CI: 71.9−88.2%), respectively, which increased to 73.3% (95% CI: 60.3−83.9%) and 83.9% (95% CI: 71.7−92.4%), respectively, in patients with a past history of tuberculosis. The sensitivity and specificity of IgG Aspergillus was 82.4% (95% CI: 71.8−90.3%) and 82% (95% CI: 73.1−89%); 86.7% (95% CI: 75.4−94.1%) and 80.4% (95% CI: 67.6−89.8%), in the whole group and those with past history of tuberculosis, respectively. Conclusions: LDBio LFA is a point-of-care test with reasonable sensitivity and specificity. However, further tests may have to be done to rule-in or rule-out the diagnosis of CPA in the appropriate setting.

Awareness, Beliefs and Perspectives Regarding Weight Retention and Weight Gain among Postpartum Women in India: A Thematic Analysis of Focus Group Discussions and In-Depth Interviews.

Background and Aims: The pregnancy weight is usually retained in the form of abdominal fat during the postpartum period. The willingness to lose weight is influenced by knowledge, attitude, beliefs and practices. This study aims to comprehend the awareness, beliefs and perspectives of postpartum women regarding their perceived factors, barriers and facilitators associated with post-pregnancy weight status. Methods: Overweight and obese postpartum women aged between 20 and 40 years and had delivered an infant in the last 2 years were recruited via convenience and purposive sampling techniques. The final sample comprised 27 participants with a mean age of 29.96 ± 4.50 years. Four focus group discussions and eight in-depth interviews carried out were audio-recorded and transcribed verbatim. Codes, sub-themes and themes were generated using Atlas.ti 9 software. Results: Major themes identified were perceived factors causing postpartum weight retention/weight gain including social and cultural beliefs related to diet and exercise specifically associated with this period, perceived motivators and deterrents of weight loss including eagerness to lose weight and perceived facilitators and barriers to weight loss including intrinsic and extrinsic factors such as time, energy, evidence-based knowledge about diet and physical activity, family support and obligation to family's advice. Conclusion: The unique challenges and barriers associated with postpartum weight loss efforts should be taken into consideration by healthcare professionals and public health policy-makers to design strategies specific to postpartum women. Supplementary Information: The online version contains supplementary material available at 10.1007/s13224-022-01644-9.

Risk factors for Coronavirus disease-associated mucormycosis.

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.

Utility of nasal application of lignocaine gel using cotton tip swab versus squirting with slip-tip syringe for transnasal fibreoptic bronchoscopy: a pilot randomised controlled trial.

BACKGROUND: During flexible fibreoptic bronchoscopy through the nasal route, anaesthesia of the nasal passage is achieved by lignocaine gel application by a slip-tip syringe or with the help of a cotton tip swab. No studies in existing literature have compared the two techniques in terms of efficacy. METHODS: 137 consecutive patients undergoing bronchoalveolar lavage (BAL) were recruited over a 2-year period. The patients underwent BAL after nasal anaesthesia-either by slip-tip syringe or by cotton tip swab smeared with 2% lignocaine gel. Patients were monitored for intraprocedural epistaxis, discomfort and improvement in operator visibility of nasal passage. RESULTS: 67 patients were randomised to cotton swab and 70 patients to the gel instillation group. There were no significant differences in terms of epistaxis, 29.9% in the cotton tip swab (95% CI 19.3% to 42.3%) versus 24.3% in the gel instillation group (95% CI 14.8% to 36%) or detection of nasal blocks, 7.5% in the cotton tip swab (95% CI 2.5% to 16.6%) versus 10% in the gel instillation group (95% CI 4.1% to 19.5%) in the two groups, although a significant difference was there in terms of visibility, 73.1% in the cotton tip swab (95% CI 60.9% to 83.2%) versus 42.9% in the gel instillation group (95% CI 31.1% to 55.3%). There was no difference in the mean pain score across the two groups either during the procedure or 1 hour after it. A short systematic review of existing literature on the topic has been provided for comparison. CONCLUSION: Application of 2% lignocaine gel by slip-tip syringe and cotton tip swab are equivalent in terms of observed and narrated pain experienced by patients, frequency of epistaxis and nasal blocks. Vision was better preserved in the cotton tip swab group.

Post COVID-19 sequelae: A prospective observational study from Northern India.

Post COVID-19 sequelae are a constellation of symptoms often reported after recovering from COVID-19. There is a need to better understand the clinical spectrum and long-term course of this clinical entity. The aim of this study is to describe the clinical features and risk factors of post COVID-19 sequelae in the North Indian population. This prospective observational study was conducted at a tertiary healthcare centre in Northern India between October 2020 and February 2021. Patients aged >18 years with laboratory-confirmed COVID-19 were recruited after at least two weeks of diagnosis, and details were captured. A total of 1234 patients were recruited and followed up for a median duration of 91 days (IQR: 45-181 days). Among them, 495 (40.1%) had persistent symptoms post-discharge or recovery. In 223 (18.1%) patients, the symptoms resolved within four weeks; 150 (12.1%) patients had symptoms till 12 weeks, and 122 (9.9%) patients had symptoms beyond 12 weeks of diagnosis/symptom-onset of COVID-19. Most common symptoms included myalgia (10.9%), fatigue (5.5%), shortness of breath (6.1%), cough (2.1%), insomnia (1.4%), mood disturbances (0.48%) and anxiety (0.6%). Patients who were hospitalized were more likely to report fatigue as a feature of long COVID. Hypothyroidism (OR: 4.13, 95% CI: 2.2-7.6, p-value < 0.001) and hypoxia (SpO2 ≤ 93%) (OR: 1.7, 95% CI: 1.1-2.4, p-value 0.012) were identified as risk factors for long COVID sequelae. In conclusion, long COVID symptoms were common (22%), and 9.9% had the post COVID-19 syndrome. Myalgias, fatigue and dyspnoea were common symptoms. Patients with hypothyroidism and hypoxia during acute illness were at higher risk of long COVID.

Development and Validation of a Comprehensive Questionnaire to Assess Interpersonal Discord (Bullying, Harassment, and Discrimination) at the Workplace in a Healthcare Setting.

Objective This study was conducted to develop and validate a comprehensive questionnaire to assess bullying, discrimination, and harassment in healthcare settings. Methodology A mixed-method study design was used to develop and validate the questionnaire. In phase I, qualitative approaches were used for the development, which included literature search, focus group discussions (FGDs), following which the construct was developed. In phase II, face validity and construct validity were established using quantitative approaches. Results The final questionnaire consists of 25 items divided into five sections addressing the burden, impact, reasons for underreporting, risk factors, and mitigation strategies. The questionnaire has very good consistency with a Cronbach's alpha score of 0.86. Conclusion This is a comprehensive tool with appropriate psychometric properties with potential use for evaluating the problem of interpersonal discord in the form of bullying, harassment, and discrimination in a healthcare setting.

Effect of Training and Checklist Based Use of Ventilator Associated Pneumonia (VAP) Prevention Bundle Protocol on Patient Outcome: A Tertiary Care Centre Study.

OBJECTIVE: VAP prevention bundle includes daily sedation free interval, DVT prophylaxis, raising head end of bed, use of orogastric rather than nasogastric tube. This study aims to study the practices regarding VAP prevention bundle and its compliance, educating about the practices and effects on patients outcome. DESIGN: Quasi-experimental study, conducted in 3 phases. SETTING: Hospital based. PARTICIPANTS: Invasive Mechanically ventilated patients in the Department of Medicine of a tertiary care hospital. 50 patients included in phase 1 and 3. INTERVENTION: Phase 1 and Phase 3 were pre and post intervention phases respectively when compliance to VAP prevention bundle was assessed with intermediate Phase 2, the intervention phase where the residents and nurses were educated about VAP bundle through various means. A checklist was attached to patient records. OUTCOME MEASURES: Incidence of VAP, total hospital and ICU stay, duration of mechanical ventilation and mortality. RESULTS: On comparing the 2 phases, it was found that there was increase in the compliance to VAP bundle(p<0.001), use of orogastric tube (p<0.001) and use of daily sedation free interval (p<0.001). Statistically insignificant increase in the use of DVT prophylaxis (p= 0.996) and raising the head end of the bed (p=0.513), and decline in the number of days of ICU(p=0.804) and hospital stay(p=0.907), the duration of mechanical ventilation(p=0.909), mortality(p=0.315) and incidence of VAP(p=0.715) was noted. Among those who developed VAP, there was lower compliance to bundle. CONCLUSIONS: Practices like use of VAP prevention bundle improve on teaching efforts and use of checklist which improves patient care.

Management of dengue with co-infections: an updated narrative review.

Dengue is a life-threatening mosquito borne viral disease. We are still in the era of supportive treatment where morbidity and mortality are a major concern. Dengue infection in presence of other co-infections makes this scenario rather worse. Timely recognition and raising alarm to be intensive is the need of the hour for primary care physicians practicing in the community and indoors. This review provides a comprehensive knowledge about the recent trends of coinfection in dengue as well as their management consideration which will be particularly helpful for physicians practicing in rural and remote areas of India.
