Identification of potential anti-mucor agents by targeting endothelial cell receptor glucose-regulated protein-78 using in silico approach

Mucormycosis is a fungal infection of the sinuses, brain and lungs that is the cause of approximately 50% mortality rate despite the available first-line therapy. Glucose-Regulated Protein 78 (GRP78) is already reported to be a novel host receptor that mediates invasion and damage of human endothelial cells by Rhizopus oryzae and Rhizopus delemar, the most common etiologic species of Mucorales. The expression of GRP78 is also regulated by the levels of iron and glucose in the blood. There are several antifungal drugs in the market but they pose a serious side effect to the vital organs of the body. Therefore, there is an immediate need to discover effective drug molecules having increased efficacy with no side effects. With the help of various computational tools, the current study was attempted to determine potential antimucor agents against GRP78. The receptor molecule GRP78 was screened against 8820 known drugs deposited in DrugBank library using high-throughput virtual screening method. Total top 10 compounds were selected based on the binding energies greater than the reference co-crystal molecule. Furthermore, molecular dynamic (MD) simulations using AMBER were performed to calculate the stability of the top-ranked compounds in the active site of GRP78. After extensive computational studies, we propose that two compounds (CID439153 and CID5289104) have inhibitory potency against mucormycosis and can serve as potential drugs that can form the basis of treating mucormycosis disease.Communicated by Ramaswamy H.

Efficacy of Rifaximin in Patients With Abdominal Bloating or Distension: A Systematic Review and Meta-analysis

BACKGROUND

Abdominal bloating is a common complaint in patients with functional and organic bowel disease. Rifaximin, a nonabsorbable antibiotic, has been tried for the treatment of this disease. We performed a systematic review and meta-analysis to study the efficacy of rifaximin in abdominal bloating and distension in patients with functional gastrointestinal disorders (FGID).

METHODS

We accessed 4 databases (MEDLINE, Embase, SCOPUS, and Web of Science) to identify randomized placebo-controlled trials that utilized rifaximin in FGID. We excluded observational studies, those including patients with organic bowel disorders such as inflammatory bowel diseases, or those in which rifaximin was given for other indications, such as hepatic encephalopathy.

RESULTS

A total of 1426 articles were available, of which 813 articles were screened after removing duplicates and 34 articles were selected for full-text review. Finally, 10 trials (3326 patients) were included. Rifaximin was administered in doses ranging from 400 to 1650 mg per day for 1 to 2 weeks. Rifaximin therapy led to a higher likelihood of improvement in symptoms of bloating (44.6% vs. 34.6%, RR 1.22, 95% CI 1.11, 1.35; n=2401 patients) without significant heterogeneity. However, daily doses less than 1200 mg/day were similar to placebo ( P =0.09). Bloating was quantified subjectively in 7 studies, and rifaximin led to a greater reduction in bloating scores compared with placebo (standardized mean difference -0.3, 95% CI -0.51, -0.1, P =0.04) but carried significant heterogeneity ( I2 =61.6%, P =0.01).

CONCLUSIONS

Rifaximin therapy is associated with an increased likelihood of improvement in bloating and distension, as well as reduces the subjective severity of these symptoms in patients with FGID.

Hyperglycemia modulates M1/M2 macrophage polarization in chronic diabetic patients with pulmonary tuberculosis infection

Increased susceptibility to bacterial infections like tuberculosis (TB) is one of the complications of type 2 diabetes, however the underlying mechanisms remains poorly characterized. To explore how chronic hyperglycemia in diabetes affects progression of active TB, we examined mRNA expression of M1 (proinflammatory) and M2 (anti-inflammatory) cytokines/markers, in monocyte-derived macrophages obtained from patients with PTB + DM (pulmonary TB + diabetes mellitus type 2), patients with DM alone, patients with PTB alone, and healthy individuals (controls). Our findings indicate a dysregulated cytokine response in patients with both PTB and DM, characterized by decreased expression levels of interferon-gamma (IFN-γ) and inducible nitric oxide synthase (iNOS), along with increased expression levels of interleukin-1 beta (IL-1β) and CD206. Furthermore, we observed a positive correlation of IL-1β and CD206 expression with levels of glycosylated hemoglobin (HbA1c) in both PTB + DM and DM groups, while IFN-γ showed a positive correlation with HbA1c levels, specifically in the PTB + DM group. Additionally, M1 cytokines/markers, IL-1β and iNOS were found to be significantly associated with the extent of sputum positivity in both PTB and PTB + DM groups, suggesting it to be a function of increased bacterial load and hence severity of infection. Our data demonstrates that tuberculosis in individuals with PTB + DM is characterized by altered M1/M2 cytokine responses, indicating that chronic inflammation associated with type 2 diabetes may contribute to increased immune pathology and inadequate control of tuberculosis infection.

Inhibition of cellular activation induced by platelet factor 4 via the CXCR3 pathway ameliorates Japanese encephalitis and dengue viral infections

BACKGROUND

Activated platelets secrete platelet factor 4 (PF4), which contributes to viral pathogenesis. Recently, we reported the proviral role of PF4 in replication of closely related flaviviruses, Japanese encephalitis virus (JEV) and dengue virus (DENV).

OBJECTIVES

This study aimed to investigate the detailed mechanism of PF4-mediated virus replication.

METHODS

PF4-/- or wild-type (WT) mice were infected with JEV, and host defense mechanisms, including autophagic/interferon (IFN) responses, were assessed. WT mice were pretreated with the CXCR3 antagonist AMG487 that inhibits PF4:CXCR3 pathway. This pathway was tested in PF4-/- monocytes infected with DENV or in monocytes isolated from patients with DENV infection.

RESULTS

PF4-/- mice infected with JEV showed reduced viral load and improved brain inflammation and survival. PF4-/- mice synthesized more IFN-α/β with higher expression of phosphorylated IRF3 in the brain. PF4 treatment decreased IRF-3/7/9 and IFN-α/β expression and suppressed autophagic LC3-II flux and lysosomal degradation of viral proteins in JEV-infected cells. PF4 increased the expression of P-mTOR, P-p38, and P-ULK1Ser757 and decreased expression of LC3-II. Decreased autophagosome-lysosome fusion in turn promoted DENV2 replication. The above processes were reversed by AMG487. Uninfected PF4-/- monocytes showed elevated LC3-II and autophagosome-lysosome fusion. Microglia of JEV-infected PF4-/- mice exhibited elevated LC3-II inversely related to viral load. Similarly, monocytes from PF4-/- mice showed reduced infection by DENV2. In patients with DENV infection, higher plasma PF4 and viral load were inversely correlated with LC3-II, LAMP-1, and lysosomal degradation of DENV-NS1 in monocytes during the febrile phase.

CONCLUSION

These studies suggest that PF4 deficiency or inhibition of the PF4:CXCR3 pathway prevents JEV and DENV infection. The studies also highlight the PF4:CXCR3 axis as a potential target to develop treatment regimens against flaviviruses.

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.

Escalate: Linezolid as an add on treatment in the intensive phase of tubercular meningitis. A randomized controlled pilot trial

Most drugs used in the treatment of Tuberculous Meningitis have limited CNS penetration thereby limiting efficacy. CSF penetration of linezolid is 80-100%.The study was a prospective, randomized, open label with blinded outcome assessment pilot trial carried out in patients with TBM. Patients were randomized in a 1:1 ratio into two treatment groups either to receive standard ATT alone or add on oral 600 mg BD Linezolid for 4 weeks along with standard four drug ATT [HRZE/S]. Primary outcome was safety and mortality at the end of one and three months measured by intention to treat analysis. 29 patients were recruited and 27 completed three months of follow up. There was no significant difference in terms of mortality with Odds ratio (95% CI) of 2 (0.161-24.87; p = 1) at one month and 0.385 (0.058-2.538; p = 0.39) at three months. There was a significant improvement in GCS in Linezolid group at one month and mRS within the Linezolid group at one and three months. No major safety concerns were observed. The sample size is underpowered to draw any definitive conclusions but improvement in mRS and GCS as well as mortality change make a case for a large sample size trial.

Hyperactive behaviour of growth differentiation factor- 15 (GDF-15) in conjunction with iron trafficking transporters and suppression of Nrf-2 gene in diabetes and metabolic syndrome

Multiple parallel factors are frequently interrogated with various toxic radicals which are abundantly generated in the liver, heart, and pancreas in stress conditions. They are actively involved in the development of diabetes and metabolic aberrations. However, whether over-activation of GDF-15mRNA and influxes of iron-by-iron trafficking genes are directly suppressing the Nrf-2 gene in patients with diabetes and metabolic aberrations in context with undiagnosed individuals with diabetes and metabolic aberrations? Therefore, we have investigated inter and intra- related Zip8/14 mRNA, GDF-15mRNA, and Nrf-2 mRNA expressions in diabetes and metabolic syndrome as it is expected to be up to 134 million by 2045 in India. We recruited 120 subjects from the Department of Medicine, Endocrinology and Metabolic Clinic, All India Institute of Medical Sciences, New Delhi, India. Various investigations related to anthropometry, nutritional, hematological, biochemical, cytokine, and oxidative stress were measured in diabetes, metabolic syndrome, diabetes with metabolic aberration, and healthy controls. Relative expression of GDF-15, ZIP8, ZIP14, Nrf-2, and housekeeping genes was done in all subjects. Stress-responsive cytokines are highly expressed in patients with metabolic aberration with respect to body weight, IR, waist circumference, and fat mass. IL-1β, TNF-α, and IL-6 levels were significantly higher in metabolic syndrome, whereas Adiponectin levels were profoundly lower side. MDA levels were significantly raised in diabetes with metabolic syndrome while SOD activities were lowered (p = 0.001). GDF-15 mRNA expression was 1.79-fold upregulated in group III as compared with Group I while 2-threefold down-regulation of Nrf-2 expression was observed in diabetes with metabolic aberration groups. Zip 8 mRNA expressions were downregulated (p = 0.014), and Zip 14 mRNA expressions were upregulated (p = 0.06) in diabetes and metabolic aberrations. The association of GDF-15 and Nrf-2 mRNA expression was found contradictory and highly interlinked with ROS. Zip 8/14mRNA expressions were also dysregulated in diabetes and metabolic-associated complications.

Central Line-Associated Bloodstream Infections: Effect of Patient and Pathogen Factors on Outcome

Introduction

Patients on central lines are often having multiple morbidities, and invasive devices provide a niche for biofilm formation, which makes central line-associated bloodstream infections (CLABSIs), a serious concern in health-care settings, as the infections difficult to treat. In this study, we evaluated the common bacteria causing CLABSI, and various patient and pathogen factors affecting the clinical outcome.

Methods

In the prospective observational study, patients diagnosed with CLABSI were recruited. Extensive clinical, microbiological, and other laboratory workup was done, and observations were recorded. Congo red agar method, tube test, and microtiter plate assay were used for eliciting the biofilm-forming attributes of the bacterial pathogens.

Results

Klebsiella pneumoniae was responsible for 48% of CLABSI, followed by Coagulase-negative Staphylococci (16%) and Staphylococcus aureus and Acinetobacter baumannii (12% each). Fifty-six percent of the isolates produced biofilms. The median (interquartile range) duration of hospital stay till death or discharge was 30 (20, 43) days. The all-cause mortality was 44%. Patients having a deranged liver function on the day of diagnosis (P value for total bilirubin 0.001 and for aspartate transaminase 0.02), and those infected with multidrug-resistant organisms (P value = 0.04) had significantly poor prognosis. The difference in the demographic, clinical, laboratory profile, and outcome of patients infected with biofilm producers and nonproducers was not found to be statistically significant.

Conclusion

The study throws light on various host and pathogen factors determining the cause and outcome of CLABSI patients. To the best of our knowledge, this is the first study trying to decipher the role of biofilm formation in the virulence of pathogens and the prognosis of CLABSI.

Barriers and facilitators in dietary and physical activity management of type 2 diabetes: Perspective of healthcare providers and patients

BACKGROUND AND AIMS

Type 2 diabetes (T2DM) is a chronic disease that requires continuous management and daily self-care activities. The purpose of the study was to identify the barriers and facilitators in dietary and physical activity management of T2DM by patients.

METHOD

Two focus group discussions with patients with T2DM (n = 12) and interviews with healthcare providers (HCPs, n = 15) were done, to identify the barriers and facilitators experienced by patients towards lifestyle management in T2DM. Data were analyzed using qualitative data analysis software Atlas ti. version 8.

RESULT

Three major themes were identified as barriers and facilitators viz., Personal barriers and facilitators, social barriers and facilitators, and barriers and facilitators related to the healthcare provider. Major barriers were denial of illness, low level of knowledge of the disease, excess use of gadgets, poor infrastructure, gender issues, and lack of time. Major facilitators identified were patient education and motivation, continuous counseling and regular follow-up, family and peer support, and recreational and indoor activities.

CONCLUSION

Based on the findings of the study, a multifaceted approach is required to address these barriers and facilitators. These findings will help in developing novel intervention strategies and making policy-level changes, which are required to improve diabetes self-management practices in people with T2DM.

Seroprevalence of Strongyloides infection among steroid recipients in a tertiary care centre in North India

BACKGROUND

Strongyloides stercoralis (S. stercoralis), a unique parasite, can cause mortal disease even years after the exposure. Iatrogenic use of steroids can complicate asymptomatic infections to a life-threatening hyperinfection and/or disseminated infection. Data regarding seroprevalence of strongyloidiasis remains scarce and this knowledge gap needs due attention in many endemic countries including India.

AIM

The present study is aimed at assessing the seroprevalence of Strongyloides infection and the need for routine screening among individuals receiving steroid therapy.

METHODOLOGY

Eighty patients receiving steroid therapy and thirty healthy volunteers who had not received any immunosuppressive drugs and/or anthelminthic therapy in last six months were enrolled as cases and controls respectively and they were screened by Strongyloides IgG ELISA.

RESULTS

Among the 80 patients on steroids, the mean cumulative prednisolone equivalent dose received was 8.2 g (±11.2 g) for a mean duration of 184 days, 16 patients (20%, 95% CI 11.9-30) had a positive Strongyloides IgG serology. Only 4 controls (4/30, 13.3%, CI 3.8-30.7) tested positive (p=0.4).

CONCLUSIONS

Our study demonstrated a Strongyloides seroprevalence of 20% in the study population emphasizing the need for screening for Strongyloides infection prior to immunosuppressive therapy in order to prevent hyperinfection or possible dissemination.

Chronic hyperglycemia drives alterations in macrophage effector function in pulmonary tuberculosis

Diabetes mellitus (DM) alters immune responses and given the rising prevalence of DM in tuberculosis (TB) endemic countries; hyperglycemia can be a potential risk factor for active TB development. However, the impact of hyperglycemia on TB-specific innate immune response in terms of macrophage functions remains poorly addressed. We assessed macrophage effector functions in uncontrolled DM patients with or without TB infection (PTB+DM and DM), non-diabetic TB patients (PTB), and non-diabetic-uninfected controls. Phagocytic capacity against BCG and surface expression of different pattern recognition receptors (PRRs) (CD11b, CD14, CD206, MARCO, and TLR-2) were measured via flow cytometry. Effector molecules (ROS and NO) required for bacterial killing were assessed via DCFDA and Griess reaction respectively. A systematic dysregulation in phagocytic capacity with concurrent alterations in the expression pattern of key PRRs (CD11b, MARCO, and CD206) was observed in PTB+DM. These altered PRR expressions were associated with decreased phagocytic capacity of macrophages. Similarly, ROS was aberrantly higher while NO was lower in PTB+DM. These altered macrophage functions were positively correlated with increasing disease severity. Our results highlight several key patterns of immune dysregulation against TB infection under hyperglycemic conditions and highlight a negative impact of hyperglycemia with etiology and progression of TB.

Validation of Tools to Assess Predictors of Successful Weight Loss Outcome in Individuals With Overweight and Obesity

OBJECTIVE

To develop and validate questionnaires to assess the behavioral, psychosocial, and environmental predictors of successful weight loss outcomes.

DESIGN

Mixed method study. Questionnaires were developed using 5 steps: item generation by literature review and preexisting questionnaires, expert evaluation, pilot testing, factor analysis, and internal consistency.

SETTING

Adults with obesity recruited via web-based survey hyperlink.

PARTICIPANTS

One hundred participants with a mean body mass index of 28.7 ± 4.4 kg/m².

VARIABLES MEASURED

The questionnaires were generated using 221 items. Establishing content, face and construct validity, and internal consistency.

ANALYSIS

Content validity was analyzed using content validity index and content validity ratio, internal consistency through Cronbach α (CA), and structural validity by factor analysis via principal varimax rotation.

RESULTS

All three questionnaires had good content validity. The Behavioral Predictor Questionnaire had good internal consistency (CA, 0.7) and excellent structural validity (69.7%). Psychosocial Predictors Questionnaire (CA, 0.8, 67.5%) and Environmental Predictors Questionnaire (CA: 0.8, 72.2%) had excellent internal consistency and structural validity.

CONCLUSION AND IMPLICATION

Questionnaires seem to be practical, valid, and reliable tools for baseline assessment of individual-specific factors related to weight loss success.

Neuroleptic malignant syndrome in a case of extra-pontine myelinolysis: On the horns of dilemma

Osmotic demyelination syndrome (ODS) and neuroleptic malignant syndrome (NMS) lead to severe neurological sequalae. Though currently thought to be different syndromes, literature suggests a relation between the two. We present the case of a 45-year-old male who was found to have chronic severe hyponatremia and underwent rapid correction of sodium and developed parkinsonism features. Magnetic resonance imaging (MRI) confirmed extrapontine myelinolysis (a type of ODS). The patient received haloperidol for agitated behavior and developed new features of rigidity, fever, tachycardia and elevated creatine phosphokinase (CPK) levels and thus neuroleptic malignant syndrome was suspected to overlap with ODS. We report this case highlighting the difficulty in differentiating the between ODS and NMS and their relationship.

A cross sectional survey of 504 women regarding perceived risk factors and barriers to follow healthy lifestyle and association with sociodemographic factors and menopausal symptoms

BACKGROUND AND AIMS

Midlife women undergoing menopausal transition are predisposed to weight gain. Weight gain in midlife is driven by two modifiable risk factors: menopausal symptom's severity and lifestyle practices. The independent and interactive nature of menopausal symptoms and lifestyle practices as risk factors of weight gain has not been investigated yet. This study was undertaken to study menopausal symptoms and lifestyle practices as risk factors for weight gain in midlife women and identify midlife -related barriers in managing corrective lifestyle practices.

METHODS

In this cross-sectional study, menopausal symptom severity and lifestyle practices such as diet, exercise, and sleep were assessed using a pre-validated and reliable questionnaire on a convenience sample of midlife women (43-55 years) via an interview schedule. The association of lifestyle practices and its barriers with socio-demographics and menopausal symptoms were analysed.

RESULT

A total of 504 women (mean age: 47.3 ± 4.1 years) were recruited. More than half of them followed corrective dietary practices, but only one-fourth engaged in moderate-intensity exercises. Total menopausal symptom severity was associated with increased food intake (P < 0.001), joint pain with limited physical activity and hot flashes and emotional volatility with sleep disturbances (P < 0.01). Demographic variables such as education, economic and employment status were associated with unhealthy lifestyle practices.

CONCLUSION

Assessment of menopausal symptoms and lifestyle practices as risk factors and associated barriers must be the pivotal component to devise comprehensive women-centric weight management modules. Similar studies should be carried out in future when there is no clear effect of COVID19 on lifestyle factors.

Clinical Profile, Treatment, and Outcome of Patients with Secondary Hemophagocytic Lymphohistiocytosis in Critically Ill Patients: A Prospective Observational Study

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.

Effect of intensive weight-loss intervention on metabolic, ultrasound and anthropometric parameters among patients with obesity and non-alcoholic fatty liver disease: an RCT

Background

Lifestyle intervention is the mainstay therapy for Non-Alcoholic Fatty Liver Disease (NAFLD). We aimed to assess the efficacy of an intensive (9 contact points in 6 months) weight-loss intervention among patients with obesity (BMI 25–39.9 kg/m²) and NAFLD in north India.

Methods

A total of 140 patients (18–60 years) with obesity and NAFLD were randomized into intervention (n = 70) and control (n = 70) groups, at a tertiary-care hospital. Weight, anthropometric parameters, Controlled Attenuation Parameter (CAP), Liver Stiffness Measurement (LSM), liver enzymes, grade of fatty liver and HOMA-IR were measured at baseline (T₀) and 6 months (T₆). There was a high drop-out, exacerbated by the Covid-19 pandemic. Completers comprised of 59 participants (n = 30 intervention, n = 29 control). Intention to treat analysis was done.

Results

At T₆, ALT normalized in significantly higher (p = 0.03) number of cases in the intervention arm (66.7%) versus control arm (18.2%). No significant improvement was seen in other metabolic, ultrasound or anthropometric outcomes. Weight (p < 0.001), AST (p = 0.01), ALT (p = 0.02), body fat% (p < 0.001), WC (p < 0.001) and CAP (p < 0.001) significantly improved within the intervention arm along with a trend of improvement in steatosis and HOMA-IR. Control group showed significant decrease in weight (p < 0.001), WC (p < 0.001) and CAP (p = 0.02). Twice the number of patients in intervention arm (46.7%) lost ≥5% weight, compared to control arm (24.1%) (p = 0.07).

Conclusion

The intensive weight-loss intervention was not effective in improving the treatment outcomes among patients with obesity and NAFLD. However, given the potential of our intervention, we recommend larger trials with more intensive weight-loss interventions.

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.

Executive summary of evidence and consensus-based clinical practice guideline for management of obesity and overweight in postpartum women: An AIIMS-DST initiative

INTRODUCTION

Postpartum obesity is a public health concern. There is a need to counsel women about their postpartum weight management, accounting for various barriers they face. Limited literature in the Indian context underscored the need to develop the clinical practice guideline to be used by healthcare providers in Indian healthcare settings.

METHODS

The guideline was formulated by following the standardised methodology proposed by the National Health and Medical Research Council. Various steps such as identification of the patient population, assembly of the guideline development groups, identification of the key clinical questions, guideline development methods, grading the quality of evidence and recommendations and guideline translation were carried out to develop and validate the clinical practice recommendations.

RESULTS

The evidence and consensus-based clinical practice guideline has been developed, providing recommendations for key topics of interest for first-line treatment of obesity (lifestyle-related management). Recommendations focus on screening and initiating discussion with overweight and obese postpartum women as well as those who had normal pre-pregnancy body mass index but have retained excessive weight in the postpartum period. Recommendations highlight the evaluation and management of dietary, physical activity and breastfeeding behaviour. Recommendations also account for behavioural modification techniques to improve adherence to the prescribed weight management advice. Duration and frequency of follow-ups as well as the advice to be disseminated have also been discussed in the recommendations.

CONCLUSION

The guideline provides clinical practice points that can be used by healthcare providers, postpartum women and policymakers for opportunistic screening and management of postpartum obesity.

Executive summary of evidence and consensus-based Clinical Practice Guidelines for management of obesity and overweight in midlife women: An AIIMS-DST initiative

BACKGROUND AND AIMS

Weight gain is an independent risk factor for decline in cardiometabolic and overall health-related quality of life in midlife women. The AIIMS-DST initiative aims to develop and validate stepwise recommendations specific for weight management in midlife women.

METHODS

The key clinical questions specific to weight management in midlife women were finalised with the help of a multidisciplinary team of experts in the guideline development group (GDG). Phase I included a systematic and/or narrative review to gather evidence, grading of evidence and expert opinion was sought to develop clinical practice recommendations for each clinical question. Phase II focused on validation of clinical practice recommendations using the peer-review, Delphi method and GRADE approach.

RESULTS

-The guidelines provide clinical practice points to address challenges encountered by midlife women in their attempts to manage obesity via lifestyle modification techniques. The initiation of discussion would help the healthcare provider to identify the weight management needs of the women, educate women on different modalities of weight management, and empower them to incorporate corrective lifestyle behaviours. Before initiating the management, a comprehensive assessment of clinical and lifestylerelated parameters should be completed. A personalised behavioural lifestyle modification program addressing the midlife specific barriers for optimal metabolic, musculoskeletal, and mental health should be planned. A consistent follow-up is required for maintenance of corrective eating and activity habits by addressing midlife specific barriers for sustenance of healthy weight.

CONCLUSION

These recommendations will be useful in opportunistic screening and management of obesity in midlife women across healthcare settings.

Identification of instruments for evaluation of behavioural and psychological parameters associated with obesity management: A systematic review with narrative synthesis of the findings

BACKGROUND AND AIMS

To identify instruments used to evaluate the predictors of successful weight loss across weight loss trials.

METHODS

We searched PubMed, PsychInfo, Cochrane Reviews and Scopus for weight loss trials reporting instruments published in the last 16 years.

RESULTS

A total of 46 significant behavioral and psychological predictors were identified, of which 32 instruments were finally selected. SF-36 questionnaire and Obesity Related Problem Scale for psychosocial health, TREMORE scale for motivation, Social Support Scale for support, Weight Efficacy Lifestyle Scale for self-efficacy and Body Shape Questionnaire for body image had moderate quality. Barriers to healthy eating questionnaire scale and Dutch Eating Behavior also had moderate quality.

CONCLUSION

Use of uniform instruments with optimum quality can benefit clinical and community-based researchers to generate reliable datasets.

The Effect of the Severity of Obstructive Sleep Apnea on Leukocyte Telomere Length, 25 Hydroxy Vitamin D, and Parathyroid Hormonal Concentrations in Asian Indians

Background: Obstructive sleep apnea (OSA) is a common disorder in which breathing repeatedly stops during sleep. Leukocyte telomere length (LTL) and OSA are linked with an increased risk of oxidative stress and inflammation. The possible link between LTL and OSA in Asian Indians has not been evaluated. Thus, the present study aims to compare the link between LTL and OSA in Asian Indians.

Methods: In this study, 300 subjects (120 obese with OSA, 110 obese without OSA, and 70 non-obese without OSA) were included after overnight polysomnography and a fasting blood sample. Clinical, anthropometry, metabolic markers, insulin, 25-hydroxyvitamin D [25(OH) D], and parathyroid hormones (PTH) levels were investigated. LTL was investigated by a QPCR. Univariate and stepwise multivariate linear regression analyses adjusting for age, gender, BMI, and % body fat were conducted while treating LTL as a dependent variable in relation to AHI and other covariates.

Results: Obese subjects with OSA had significantly decreased 25(OH)D and increased PTH levels. The mean telomere length (T/S) ratio was significantly shorter in patients with OSA. The adjusted correlation analysis showed that shortening of telomere length correlated with increasing age, apnea-hypopnea index (AHI), oxygen desaturation index, and RDI. Univariate analysis showed that LTL revealed a trend toward a negative correlation with a mean age (β + SE, −0.015 + 0.0006; p = 0.01) and positive correlation with AHI [β +slandered error (SE), 0.042 + 0.017; p = 0.008]. In the multiple regression analysis, LTL was positively associated with AHI (β + SE, 0.281 + 0.04; p = 0.001) after adjusting for age, sex, BMI, and % body fat. Even when adjusted for confounding factors, 25(OH)D, and PTH levels, LTL still was related to AHI (β + SE, 0.446 + 0.02; p = 0.05).

Conclusion: Our study indicates the presence of an association between LTL and OSA and a significant impact of OSA severity and telomeres shortening in Asian Indians.

Weight management in postpartum women - An Indian perspective

BACKGROUND AND AIMS

This narrative review is intended to present an evidence and opinion-based weight management module for Indian postpartum women to be used by clinicians.

MATERIAL AND METHODS

Electronic databases such as PubMed and Google Scholar were accessed to extract relevant studies to derive evidence-based information. The reference list of the extracted studies was also checked to obtain further relevant articles. The opinion-based information was achieved from the consensus among the gynaecologists, nutritionists and doctors from Medicine according to their practical experiences in real time. In this review, we have used the term "postpartum" to represent the time period of two years after delivery.

RESULTS

A postpartum weight management module consisting of information about diet, physical activity, sleep and breastfeeding was devised to be used in regular clinical practice, particularly in the Indian settings.

CONCLUSION

Postpartum women deal with various unique challenges as compared to other population groups. Individualised weight management strategies should be adopted to facilitate sustainable postpartum weight management.

Magnitude of psychiatric comorbidity in patients with obesity in Northern Indian population

BACKGROUND AND AIMS

To determine the prevalence of different psychiatric comorbidities in patients with obesity and study their relationship with the degrees of obesity.

METHODS

This cross-sectional study included 151 patients with a BMI≥25 kg/m². Subjects with diagnosed psychiatric illness, type 2 diabetes mellitus, coronary artery disease or any neurological illness were excluded. Prevalence of psychiatric comorbidities was assessed by MINI screening tool for all major axis 1 disorders including anxiety, eating and mood disorders. The WHOQOL-BREF was used for assessment of well-being, in the four domains, physical, psychological, social and environmental.

RESULTS

Females constituted 68.6% of the study population. Lifetime diagnosis of any psychiatric illness was present in 24%, higher in females than males [31% vs 9%, p = 0.003]. The WHOQOL-BREF average scores of psychological, physical and environmental domains were significantly lower (p < 0.001) in patients diagnosed with depression as compared to those without. The WHOQOL-BREF average score of only the physical domain were significantly lower in individuals with BMI ≥30 kg/m² as compared to those with BMI <30 kg/m².

CONCLUSIONS

The burden of undiagnosed psychiatric comorbidity in patients with obesity decreases the quality of life. There is need to screen for psychiatric comorbidities for effective management of obesity.

Perceived barriers and facilitators for adherence to lifestyle prescription: Perspective of obese patients with non alcoholic fatty liver disease from north India

BACKGROUND AND AIMS

This study aims to identify the barriers and facilitators faced by obese patients with NAFLD from north India, while undergoing lifestyle-modification.

METHODS

30 obese patients with NAFLD were interviewed regarding the barriers and facilitators to lifestyle change and responses were noted. Inductive thematic analysis was used.

RESULTS

Eight themes under barriers (lack of family support, difficult intervention, work-related, financial, psychological, social, physical and infrastructure related) and four themes under facilitators (family support, intensive nature of intervention, psychological and physiological) were identified from the reponses.

CONCLUSIONS

Personalized and socio-culturally appropriate counseling strategies may promote successful treatment outcomes among these patients.

Development and validation of a questionnaire to assess knowledge, attitude, practices, and concerns regarding COVID-19 vaccination among the general population

BACKGROUND AND AIMS

There seems to be hesitation in the general population in accepting COVID 19 vaccine because of associated myths and/or misinformation. This study is dedicated to develop and validate a tool to interpret vaccine acceptance and/or hesitancy by assessing the knowledge, attitude, practices, and concerns regarding the COVID vaccine.

MATERIAL AND METHODS

Mixed methods study design was used. In phase 1, the questionnaire was developed through literature review, focus group discussion, expert evaluation, and pre-testing. In phase 2, the validity of the questionnaire was obtained by conducting a cross-sectional survey on 201 participants. The construct validity was established via principal component analysis. Cronbach's alpha value was used to assess the reliability of the questionnaire.

RESULTS

The 39-item questionnaire to assess the knowledge, attitude, practices, and concerns regarding the COVID-19 vaccine was developed. The Cronbach's alpha value of the questionnaire was 0.86 suggesting a good internal consistency.

CONCLUSION

The developed tool is valid to assess the knowledge, attitude, practices and concerns regarding the COVID-19 vaccine acceptance and/or hesitancy. It has the potential utility for healthcare workers and government authorities to further build vaccine literacy.

What Indians Think of the COVID-19 vaccine: A qualitative study comprising focus group discussions and thematic analysis

BACKGROUND AND AIMS

The study aims to interpret current knowledge, attitude, perceptions and concerns regarding COVID-19 vaccine in the Indian population.

METHODS

Eight focus group discussions were conducted. Participants were recruited via purposive sampling. Discussions were recorded and transcribed verbatim. Key themes were extracted using thematic analysis method.

RESULTS

There were 19 males and 24 females, with a mean age of 36 ± 11 years. Sub-themes identified were knowledge, attitude, perception and concerns regarding COVID-19 vaccine, leading to the main theme, i.e., views about the COVID-19 vaccine.

CONCLUSION

People have mixed perceptions regarding COVID-19 vaccine. Channelling correct messages may improve people's willingness to get vaccinated.

Knowledge, barriers and facilitators regarding COVID-19 vaccine and vaccination programme among the general population: A cross-sectional survey from one thousand two hundred and forty-nine participants

BACKGROUND AND AIMS

The success of the COVID-19 vaccination program is dependent on people's knowledge and attitude regarding the vaccination program. Higher vaccine acceptance can be ensured by strengthening the facilitators and limiting the barriers being observed among the general population.

MATERIAL AND METHODS

Indexed study is a cross-sectional web-based survey using a pre-validated questionnaire to assess knowledge, barriers and facilitators of COVID-19 vaccine and vaccination programme administered on adults across India using a Google online survey platform.

RESULTS

A total of 1294 responses (age: 38.02 ± 13.34 years) were collected. Most of the participants had limited knowledge regarding the eligibility of vaccines in vulnerable population groups such as people with allergies (57.89%) and immune-compromised patients (62.98%), pregnant and lactating women (41.89%) and patients with chronic illness (34.78%). Older participants (>45 years) were more willing to take the COVID-19 vaccine (p < 0.001) as they believed the vaccine is not harmful and considered it as societal responsibility. Younger participants (<45 years) and those residing in urban settings raised concerns on the availability of the vaccine and authenticity of the vaccine (p < 0.001).

CONCLUSION

There is a scope for improvement in people's knowledge regarding COVID-19 vaccine and the vaccination programme by addressing the barriers and facilitators which can improve the participants' turnover at vaccination centres.

Variation in Lifestyle-Related Behavior Among Obese Indian Patients With Non-alcoholic Fatty Liver Disease

Lifestyle modification is the mainstay of treatment in Non-Alcoholic Fatty Liver Disease (NAFLD). Published Indian data on the diet and lifestyle of Indian NAFLD patients is scarce. This study explored variation in lifestyle-related behavior among obese patients with NAFLD. Ultrasonography (USG) diagnosed obese NAFLD patients (n = 140) were assessed for dietary intake [1-day 24 hours recall, food-frequency questionnaire (FFQ)] and physical activity (PA) [Global Physical Activity Questionnaire (GPAQ)]. Diet quality score (0–30) and physical activity (PA) levels were used to study variation in lifestyle and assess the effect of lifestyle on the severity of NAFLD. Compared to the recommendation, calorie consumption was 25.2% higher in nearly half (53.6%) of the subjects and mean macronutrient intake was imbalanced (60.3% carbohydrates, 12.4% protein, 25.5% fats). Variation was seen in terms of diet quality—good (3%), moderate (54.3%), or poor (43.5%) and intensity of PA—high (15%), moderate (47.9%), or low (37.1%). No patient had a combination of high PA and good diet quality within all grades of NAFLD. Our study suggests wide variation in lifestyles of obese patients with NAFLD and need for a more flexible and individualized modification of their diet and PA.

Predictors of successful weight loss outcomes amongst individuals with obesity undergoing lifestyle interventions: A systematic review

Understanding the predictors of weight loss with lifestyle interventions can help to ascertain the probable outcomes of individuals with obesity who undergo such interventions. This systematic review assessed the evidence of predictors of successful weight loss among individuals who are overweight or with obesity undergoing lifestyle interventions. Four electronic databases (PubMed, Cochrane Reviews, PsychInfo and Wiley) were searched to find relevant literature published in the past 20 years. A total of 1351 titles were identified in the initial search, of which 23 studies were finally included. Predictors were synthesized in the domains of socio-demographic factors, anthropometric parameters, psychological and behavioural factors and intervention-based factors. The overall quality of evidence on predictors was then appraised using an adapted GRADE approach. Patient-specific factors such as being male, older in age, having existing cardiometabolic comorbidities and limited fat intake were significantly associated with weight loss success. Amongst intervention specific predictors, greater initial weight loss and higher adherence to lifestyle advice were associated with greater weight loss success. In this review, initial weight loss came out to be as the most important predictor of successful weight loss outcome.

Role of Diffusion-Weighted Magnetic Resonance Imaging in the Diagnosis and Grading of Hepatic Steatosis in Patients With Non-alcoholic Fatty Liver Disease: Comparison With Ultrasonography and Magnetic Resonance Spectroscopy

BACKGROUND

Nonalcoholic fatty liver disease (NAFLD) is becoming the most common cause of cirrhosis. Although magnetic resonance spectroscopy (MRS) is considered the gold standard, it has a few limitations. The role of diffusion-weighted imaging (DWI), which is a simpler sequence, in the diagnosis and grading of fatty liver is not well studied. The aim of the study was to investigate the value of DWI in the diagnosis and grading of hepatic steatosis in patients with NAFLD.

MATERIALS AND METHODS

Fifty-one adults (mean age: 38 years; 28 men, 23 women) with NAFLD, diagnosed clinically and by ultrasonography (USG), were included in the study after obtaining informed consent and approval from the institute ethics committee. USG was performed for grading of hepatic steatosis in all patients, followed by magnetic resonance imaging with DWI and MRS, on a 1.5T scanner. The mean apparent diffusion coefficient (ADC) values and proton density fat fraction (PDFF) were calculated, and MRS was used as the gold standard. The mean ADC values were compared with the PDFF and USG grades.

RESULTS

There was a weak correlation between ADC values and PDFF (r = -0.36; P < 0.05). In addition, there was a weak correlation between the ADC values of the liver and USG grade (r = -0.34; P < 0.05). However, an overall increase in USG grades and PDFF was associated with decrease in the mean ADC value (P < 0.001).

CONCLUSION

DWI is not accurate in the diagnosis and grading of hepatic steatosis in patients with NAFLD. However, a significant increase in fat deposition in the liver lowers the ADC values.

A short questionnaire to assess changes in lifestyle-related behaviour during COVID 19 pandemic

BACKGROUND AND AIMS

The lasting impact of COVID 19 pandemic and associated restrictions are bound to be significant on lifestyle-related behaviour including diet, physical activity and sleep which is one of the important components in the management of diabetes mellitus and metabolic syndrome. This study was conducted to develop and validate a questionnaire to assess changes in individual's lifestyle-related behaviour during COVID 19 pandemic.

MATERIALS AND METHODS

The questionnaire was developed through a standardised methodology including literature review, focus group discussion, expert evaluation, pre-testing and validation. The face validity and content validity of the questionnaire were analysed. A cross-sectional survey was carried out on 103 participants to validate the questionnaire that used a 5-point Likert scale for the response option. Exploratory factor analysis was performed to establish construct validity. Cronbach's alpha was calculated to test the internal consistency of the whole questionnaire.

RESULTS

A questionnaire with 20 items to assess the lifestyle-related behaviour of people was developed. The questionnaire shows a satisfactory validity and a good internal consistency with the Cronbach's alpha value of 0.72.

CONCLUSION

The developed tool is valid and reliable to assess the changes in lifestyle-related behaviour of individuals during COVID 19 pandemic.

Is excess weight a risk factor for the development of COVID 19 infection? A preliminary report from India

BACKGROUND AND AIM

This study explored the association between BMI and COVID-19 positive status in a tertiary care hospital from New Delhi.

METHODS

Three hundred and seventy nine adult patients who presented to COVID-19 screening outpatient department of the hospital were interviewed over the phone regarding their body weight and height. The COVID-19 RT-PCR report of the patients was extracted from the hospital information system.

RESULTS

The mean BMI and the prevalence of obesity was observed to be higher in individuals who were detected to be COVID-19 RT-PCR positive as compared to those who were negative. With every one-unit increment in BMI above 23 kg/m², the odds of being COVID-19 positive increased by 1.8 times among these patients.

CONCLUSION

The findings suggest a dose-response association between BMI and the odds of COVID-19 infection in individuals with excess weight.

Impact of COVID-19 on lifestyle-related behaviours- a cross-sectional audit of responses from nine hundred and ninety-five participants from India

BACKGROUND AND AIMS

The impact of measures taken to contain COVID-19 on lifestyle-related behaviour is undefined in Indian population. The current study was undertaken to assess the impact of COVID-19 on lifestyle-related behaviours: eating, physical activity and sleep behaviour.

METHODS

The study is a cross-sectional web-based survey. A validated questionnaire to assess the changes in lifestyle-related behaviour was administered on adults across India using a Google online survey platform.

RESULTS

A total of 995 responses (58.5% male, mean age 33.3 years) were collected. An improvement in healthy meal consumption pattern and a restriction of unhealthy food items was observed, especially in the younger population (age <30 years). A reduction in physical activity coupled with an increase in daily screen time was found especially among men and in upper-socio-economic strata. Quarantine induced stress and anxiety showed an increase by a unit in nearly one-fourth of the participants.

CONCLUSIONS

COVID-19 marginally improved the eating behaviour, yet one-third of participants gained weight as physical activity declined significantly coupled with an increase in screen and sitting time. Mental health was also adversely affected. A detailed understanding of these factors can help to develop interventions to mitigate the negative lifestyle behaviours that have manifested during COVID-19.

Lifestyle-related advice in the management of obesity: A step-wise approach

Obesity is a commonly encountered health-care problem that is an independent risk factor for chronic metabolic complications. Primary care physicians are the first point of contact in the management of obesity. Weight management is a step-wise intensification of interventions that initiates with lifestyle modification. Dietary and physical activity advices are integral components of all weight loss consultations and should ideally be imparted by a dietician or a nutritionist. In case of their nonavailability, the onus for lifestyle counseling rests with the physician. The prescription for a low-calorie diet coupled with increased physical activity might seem simple, but the success lies in compliance and sustainability of this advice. Compliance can be enhanced through patient-specific diet and activity plans along with corrections in eating and activity behavior. Barriers in patient's environment must also be addressed to achieve sustainable weight loss. This review covers practical insights in standard lifestyle management techniques, which can help the physicians to set better weight loss goals, adapt to patient specific lifestyle counseling, and apply strategies to enhance compliance for sustained weight loss.

Antibiotic stewardship initiative in a Medicine unit of a tertiary care teaching hospital in India: A pilot study

Background & objectives:

The models for implementation of antibiotic stewardship programme (ASP) in the acute care settings of developing countries are lacking. In most of the hospitals, patient turnover is high and a proper system for recording antibiotic-related information and tracking hospital-acquired infections is not in place. This pilot study was conducted in a tertiary care teaching hospital in north India to assess the feasibility of implementation of an ASP in a Medicine unit and to evaluate the effect of implementation as per the criteria applicable in this set up.

Methods:

A pre-post-quasi-experimental non-randomized study was conducted in two phases. In the first phase, current practices in the Medicine wards were observed. In the second phase, the ASP was implemented in a single Medicine unit, along with prospective audit and feedback, tracking of the process, as well as outcome measures. Patient risk stratification, blood culture on day one, day 3 bundle, dose optimization, de-escalation and intravenous to oral conversion of antibiotics were the key elements focused upon.

Results:

There was a significant improvement in the appropriateness of antibiotic prescription (66 vs. 86%, P<0.001) and reduction in the mean number of antibiotics used per person (4.41 vs. 3.86, P<0.05) along with decrease in the duration of hospital stay (17 vs. 14 days, P<0.05). There was a significant improvement in sending of blood cultures on day one during the stewardship phase (P<0.001).

Interpretation & conclusions:

The ASP approach used in our pilot study may be feasible and beneficial. However, it needs further confirmation in other settings and on a large scale.

Metronidazole induced encephalopathy: A rare side effect with a common drug

In hospitals, seizures and encephalopathy are one of the common complications observed in critically ill patients. Drug intoxication, metabolic derangements, and anatomical abnormalities can cause altered mental status. We encountered an uncommon case with a diagnostic dilemma due to persistent encephalopathy, where metronidazole toxicity was an etiological factor. A 45-year-old male, who was admitted with the diagnosis of ruptured amoebic liver abscess. During the course of his management, he developed seizures and altered sensorium. After excluding other etiologies for in-hospital de novo seizure, a suspicion of metronidazole toxicity was considered. MRI brain was done which suggested the same. Metronidazole induced encephalopathy (MIE) is an uncommon adverse effect of treatment with metronidazole. Diagnosis is made by identifying specific radiological findings. It characteristically affects the cerebellum and subcortical structures. While the clinical and neuroimaging changes are usually reversible, persistent encephalopathy with poor outcomes may occur as seen in our case.

Metastatic amebic brain abscess: A rare presentation

Amebiasis is an endemic protozoal infection in developing countries. Extra-intestinal involvement in the form of abscess is frequently seen in liver and lungs. The occurrence of amebic brain abscess is a rare and life-threatening presentation of systemic amebiasis. Here, we report a case of a young male who simultaneously presented with amebic liver and brain abscesses. He was successfully managed with intravenous metronidazole, other antibiotics, and drainage of both brain and hepatic abscesses along with supportive measures. The rare occurrence of this simultaneous presentation of amebic hepatic and brain abscess, prompted us to report this case.

Role of Magnetic Resonance Imaging in the Monitoring of Patients with Nonalcoholic Fatty Liver Disease: Comparison with Ultrasonography, Lipid Profile, and Body Mass Index

AIM

The aim of this study was to study the role of magnetic resonance imaging (MRI) in monitoring hepatic fat content in cases of nonalcoholic fatty liver disease (NAFLD).

MATERIALS AND METHODS

41 adults (mean age: 39 years, 22 males; 19 females) with NAFLD were included after obtaining approval from the institutional ethics committee. The baseline clinical (weight, body mass index [BMI]) and biochemical parameters, fatty liver grade on ultrasonography (USG), and hepatic fat signal fraction (FSF) using dual-echo chemical shift imaging and proton density fat fraction on magnetic resonance spectroscopy (MRS-PDFF) were assessed, before and after intervention (dietary and lifestyle changes and oral vitamin E for six months). They were categorized into Group A (good compliance to intervention) and Group B (poor compliance), and the clinical and imaging parameters were compared between them.

RESULTS

After intervention, Group A (n = 30) showed significant reduction in BMI (28.35 ± 3.25 to 27.14 ± 3.24 kg/m²; P < 0.001), hepatic FSF (19.30 ± 9.09% to 11.18 ± 7.61%; P < 0.05), and MRS-PDFF (18.79 ± 8.53% to 10.64 ± 6.66%). In Group B (n = 11), there was significant increase in BMI (28.85 ± 2.41 to 29.31 ± 2.57 kg/m²; P < 0.001), hepatic FSF (18.96 ± 9.79% to 21.48 ± 11.80%; P < 0.05), and reduction in high-density lipoproteins (P < 0.05). Although there was good correlation between USG and MRS in quantifying liver fat (r = 0.84-0.87; P < 0.001), USG was unable to detect <5.3% change in hepatic fat. There was poor correlation between lipid profile and MRS-PDFF. Change in body weight significantly correlated with change in hepatic fat content (r = 0.76; P < 0.001).

CONCLUSION

MRI is useful in accurately quantifying and in monitoring hepatic fat content and is better than clinical and biochemical parameters and USG.

Lifestyle Intervention Framework for Obese Patients with Non-alcoholic Fatty Liver Disease - a Tool for Health Professionals in Resource Constraint Settings

Purpose

Non-alcoholic fatty liver disease (NAFLD), is recognized as a health care burden worldwide. Lifestyle modification remains the first line of treatment. However, the real challenge is ensuring the patient's adherence to lifestyle modification measures, especially in hospitals with resource-limited settings.

Methods

We developed a six-month-long, dietitian-led, hospital-based, lifestyle intervention framework for obese NAFLD patients and evaluated its content. Literature review, interviews, and discussions with 10 health experts (general physicians, dietitians/nutritionists, gastroenterologists, and a clinical psychologist) and 45 NAFLD patients (35 in Phase I and 10 in Phase II) in a tertiary hospital of India were carried out.

Results

The lifestyle intervention framework has unique features, such as an intensive nature to ensure adherence, a comprehensive educational format with clear guidelines, the customization of a prescription as per individual patient requirements, and a holistic approach to inculcate self-monitoring and behavioral change in NAFLD patients.

Conclusion

Health professionals worldwide can use this lifestyle intervention framework to develop counseling interventions for better adherence among obese NAFLD patients.

2654. Myocarditis in Dengue: A Prospective Observational Study

Background

Cardiac involvement in dengue fever is underdiagnosed due to low index of suspicion and overlapping clinical manifestations of capillary leak associated with dengue. The frequency of subclinical dengue myocarditis and its relative contribution to the hemodynamic instability in severe dengue needs to be explored. We studied the prevalence of myocarditis and clinical outcomes among admitted patients with dengue.

Methods

A prospective observational study was carried out in admitted patients with age between 18 and 65 years having confirmed dengue (NS1/IgM ELISA). Patients with electrolyte abnormalities or on medications affecting heat rhythm/ rate, pre-existing heart disease were excluded. The baseline demographic, clinical and laboratory parameters were collected. A baseline ECG was done and repeated every second day. Trop-I and NT-proBNP were done at baseline and repeated only if elevated at baseline or there were ECG changes. The cardiac enzymes were measured using enzyme-linked fluorescent assay (VIDAS, bioMérieux, France). Patients with elevated enzymes underwent 2-dimensional echocardiography. Diagnosis of myocarditis was as per ESC 2013 criteria. Fluid management was as per WHO guidelines (2009).

Results

A total of 183 patients were recruited with median age of 29 years (IQR 21, 37) and 31% were females. Dengue with warning signs was present in 80 (44%) and severe dengue in 45 (25%) patients. Cardiac enzymes were elevated in 27 (15%) patients (cTnI in 25, NT-proBNP in 22). Among these 27 patients, 11 [6% (2.6–9.4, 95% CI)] had echo evidence and diagnosed as having myocarditis according to ESC 2013 criteria (Figure 1). Clinical features of fluid overload were more common in myocarditis group [8 (73%) vs 4 (2%), P = Overall, 5 (2.7%) patients expired, all of them had myocarditis (5/11 = 45%). These patients had severe dengue, 2 patients developed hospital-acquired pneumonia and 1 had malaria co-infection. Among patients with raised enzymes and normal echo (n = 16), 3 patients developed clinical signs of fluid overload compared with only 1 out of 156 patients without raised enzymes (P < 0.01).

Conclusion

Myocarditis in admitted patients with dengue is not uncommon [6% (2.6–9.4, 95% CI)] and may lead to a complicated disease course.

Vitamin D status of adult females residing in Ballabgarh health and demographic surveillance system: A community-based study

BACKGROUND

Vitamin D deficiency (VDD) is widespread, yet it is the most underdiagnosed and undertreated nutritional deficiency in the world. The prevalence of VDD is estimated to affect over 1 billion people worldwide.

OBJECTIVES

The present study was conducted to estimate the prevalence of VDD among adult females aged 20-60 years residing in a rural community of North India, and to find its association with various sociobehavioral risk factors.

METHODS

The present study is an analytical cross-sectional study conducted among females aged 20-60 years in rural Ballabgarh. Four hundred women were randomly selected from one of the villages of the Health and Demographic Surveillance System. Semi-structured, pretested interview schedule was administered to the study participants. Fasting venous blood sample was collected for the measurement of plasma sugar level and Vitamin D (25-hydroxyvitamin D).

RESULTS

The prevalence of VDD was 90.8% (95% confidence interval [CI] - 87.5-93.3), while that of Vitamin D insufficiency was 8.9% (95% CI - 6.4-12.2). On logistic regression analysis, 24 h calorie intake, protein intake, and prediabetes status of the participants were significantly associated with VDD.

CONCLUSION

Very high prevalence of VDD was observed among the females (20-60 years) residing in rural Ballabgarh.

Prevalence, clinical & biochemical correlates of non-alcoholic fatty liver disease in overweight adolescents

Background & objectives:

Non-alcoholic fatty liver disease (NAFLD) characterized by excessive accumulation of fat in the liver, which can progress to inflammation, and cirrhosis, has emerged as an important complication of obesity in adults as well as children. This study was undertaken to assess the prevalence of NAFLD and its correlation with clinical and biochemical parameters in overweight Indian adolescents.

Methods:

In this cross-sectional study, 218 overweight adolescents aged 10 to 16 yr and their parents were included. Measurements included anthropometry, ultrasonography to diagnose NAFLD, fasting glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lipids for adolescents and parents, and additional parameters of blood pressure, body fat percentage (BF%), fasting insulin, apolipoprotein C3, tumour necrosis factor-α and adiponectin for adolescents. The variables were compared between adolescents with and without NAFLD, and logistic regression analysis was performed.

Results:

Mean age and body mass index (BMI)SD score (SDS) were 11.9±1.6 yr and 2.3±1.1, respectively. NAFLD was seen in 62.5 per cent of the adolescents. The prevalence of NAFLD in the parents was similar among the adolescents with and without NAFLD, while BMI and waist circumference SDS, BF per cent, blood pressure (BP), ALT, AST, insulin and homeostatic model assessment of insulin resistance (HOMA-IR) were significantly higher in the adolescents with NAFLD. On multiple logistic regression, abdominal obesity, HOMA-IR and BF per cent were independently associated with NAFLD with odds ratios (95% confidence interval) of 2.77 (1.40-5.47), 2.21 (1.16-4.21) and 2.17 (1.12-4.22), respectively.

Interpretation & conclusions:

NAFLD was noted among nearly two-thirds of the overweight adolescents. An independent association was observed between abdominal obesity, HOMA-IR and body fat percentage and NAFLD in overweight adolescents.

Compliance of WHO Guideline on Dengue Management among Indian Patients: An Interventional Quality Improvement Study

INTRODUCTION

Dengue fever management is guided by WHO guideline, the recent one being 2009; however, compliance to the guideline is difficult to assess and in India there is no data on it. The present study, a longitudinal pre-post interventional quality improvement study, was done to determine the compliance to the guideline on dengue patients before and after resident physicians' training during two peak seasons and their impact on survival.

METHODS

This study was conducted in a tertiary health care centre in North India over 18 months. Data of hospitalized patients who admitted with dengue fever diagnosis in a peak season was collected in the form of quality indicators as described by the WHO-2009 guideline on dengue. Resident physicians were then given appropriate training about the guideline during the off season. Data of new dengue patients in next peak season after resident training was collected and compared with the baseline by standard statistical tests.

RESULTS

The post-intervention compliances of all components increased (total mean score by giving one point to each of the quality indicators reached 7.9 from 6.4). The compliance to individual indicator also increased: the admission criteria (baseline, 44% to post-intervention, 52%, p = 0.37), classification criteria (91.7% to 96%, p = 0.33), correct staging/triage (42.9% to 86%, p <0.001), vitals monitoring (85.7% to 92%, p = 0.28), correct usage of bolus fluids (34.3% to 69.5%, p <0.001), crystalloid as choice of fluid (100% in both groups), proper fluid titration (26.2% to 56%, p <0.001), hematocrit monitoring (95.2% to 98%, p = 0.42), platelet transfusion when indicated (65.5% to 58%, p = 0.39), antibiotic use when required (61.5% to 80%, p = 0.03), and discharge criteria (100% in both groups). The mortality decreased from 7.1% (baseline) to zero (post-intervention). The median duration of hospital stay also reduced by 1 day.

CONCLUSION

The study affirms that the compliance to WHO guideline on dengue management in India can be further improved by regular physician training on the guideline. Simultaneously, this educational intervention not only improves patient outcomes but also direct proper resource utilization especially platelet transfusion and antibiotic use. Furthermore, every hospital/institute should have an internal quality improvement program like this to improve the management of dengue patients. Future studies are needed to understand various barriers to 100% implementation of the guideline.

Treatment of Pulmonary Embolism with Chemotherapy in a Case of Newly Diagnosed Osteosarcoma

A 21-year old female, recently diagnosed with osteosarcoma of right humerus, presented to the emergency with history of fever, productive cough, chest pain and progressive respiratory distress for six days. Initial investigations suggested pneumonia but she did not respond to parenteral antibiotics. CT pulmonary angiogram revealed bilateral pulmonary artery embolism. Thrombolysis was performed using alteplase, which failed to improve the clinical condition. In view of underlying malignancy, a possibility of tumour-embolism was considered and she was started on chemotherapy for osteosarcoma. There was dramatic improvement in her respiratory symptoms after the first chemotherapy cycle, along with radiological resolution of the embolism. This case highlights the importance of suspecting tumour embolism in a known case of malignancy with respiratory distress.

Questionnaire to assess adherence to diet and exercise advices for weight management in lifestyle-related diseases

Background:

Lifestyle-related diseases have assumed significant public health problem across the globe including developing nations. High rate of nonadherence to treatment poses challenges to family physicians in its treatment.

Objective:

To develop a valid and reliable questionnaire for assessment of adherence to lifestyle modification advices.

Materials and Methods:

The questionnaire was developed following a systematic, scientifically accepted methodology which included literature review, focused group discussions, detailed interviews, and expert evaluation. Comprehensibility, replicability, face validity, content validity, patient acceptance, and ease of usage of the questionnaire were analyzed. Five-point Likert scale was employed as response options. Cronbach's alpha was calculated to assess internal consistency of overall questionnaire. A cross-sectional survey was then performed on 100 obese patients with nonalcoholic fatty liver disease to validate the questionnaire.

Results:

The developed questionnaire consists of 14 questions under two domains, 12 items under diet and 2 items under the physical activity domain. Each of these questions is on a 5-point Likert scale. The tool has shown satisfactory validity. It also has adequate reliability and internal consistency with Cronbach's alpha value of 0.9.

Conclusion:

It is a valid and reliable tool which can be used in clinical practice to assess adherence to lifestyle modification advices by family physicians.

Weight Management Module for Perimenopausal Women: A Practical Guide for Gynecologists

Menopause has been identified as a high-risk stage for weight gain in a woman's lifecycle. Menopause-related weight gain is a consequence of low circulating estrogen levels due to progressive loss of ovarian function. Moreover, the changes in the hormonal milieu, chronological aging, decline in physical activity coupled with westernized dietary pattern, and recurrent emotional eating episodes associated with psychological distress also contribute to the increase in total body fat and waist circumference. Higher waist circumference is an independent risk factor for cardiovascular and metabolic disease in menopausal women. These obesity-related cardiometabolic risk factors and menopausal symptoms can be effectively managed by achieving clinically significant weight loss through lifestyle modification. Behavioral lifestyle intervention uses behavioral techniques for counseling corrective dietary and physical activity practices in achieving sustainable weight loss outcomes. Majority of menopausal women seek this counseling from gynecologist, especially in primary care settings due to nonavailability of multidisciplinary teams. Thus, the aim of the review is to understand the menopause-obesity link, associated risk factors, and its health-related burden in perimenopausal women to devise a practical women-centric weight management module based on lifestyle modification techniques to address the burden of menopausal obesity in regular gynecological practice.
