Effect of aluminium on lipid profile and atherogenic index in prepubertal and young adult female rats: A pilot study

Objectives: Exposure of aluminium (Al) to mankind is inescapable, and its dyslipidaemic impact is a possible contributing factor to health hazards like cardiovascular diseases. The health effects due to the metalloestrogenic property of the metal need imperative consideration. The current experimental work was undertaken to explore Al-induced dyslipidaemia due to its metalloestrogenic property. Materials and Methods: To fulfil this objective, prepubertal (PP) and young adult (YA) female Wistar rats were intraperitoneally administered to two doses of Al [5 and 10 mg/Kg body weight (BW)] once daily for 2 weeks. After the completion of the acute exposure protocol, plasma and hepatic tissue lipid profiles were estimated. Analysis of variance was carried out by the Kruskal–Wallis test and the differences between the groups were analysed by Mann–Whitney U post hoc test Results: Increased triglyceride, total cholesterol, low-density lipoprotein (LDL) cholesterol and very-LDL cholesterol in plasma were found in YAs treated with both doses of Al in a dose-dependent manner. Similar changes were not present in PP female rats. Decreased levels of lipid levels were observed in the case of hepatic lipid profile. Conclusion: The study ushers light towards the dyslipidaemic alterations in experimental female rats after acute Al exposure. Impacts of Al on the growth and organosomatic index during the vital developmental days were significantly decided by the pubertal status of the female rats. The results of this study indicate the impact of puberty on the Al-induced modifications in lipid profile parameters and cardiovascular risk factors.

Leprosy Skin Lesion Detection: An AI Approach Using Few Shot Learning in a Small Clinical Dataset

This is an exploratory research study to check if artificial intelligence (AI) based image marker tool can aid leprosy screening to detect leprosy cases early in field situation and reduce the financial and personnel burden. We aimed to collect clinical leprosy skin lesion images and develop an AI model to identify and differentiate them. A total of 368 clinically diagnosed leprosy and 28 non-leprosy skin lesions were collected by an expert leprologist from 151 eligible patients using a multimodal imaging protocol. A Siamese-based Few Shot Learning (FSL) model was trained as it is a meta learning approach on an extremely small data set with fewer disease classes (disease conditions as categories). The number of class labels were increased by fine-grained grouping of skin lesions based on skin morphology (Nine leprosy subgroups) and further divided into train-set and test-set. An AI model was successfully developed, and the results indicated an accuracy of 91.25% and 73.12% on train-set and test-set for two-way one-shot task, respectively. The best sensitivity-specificity for the test-set were 72.39%-73.66% (two-way one-shot task). This early research data indicates that the development of AI based leprosy screening application is feasible using the skin lesion image as marker. The FSL method was successfully used in this training the small data set. However, this is a small sample size study, and more leprosy cases need to be enrolled along with an equal number of non- leprosy cases while improving model architecture to reduce overfit or bias problem. Moreover, as of now this tool cannot be used for neural leprosy (having no skin lesion) as well as lepromatous leprosy having diffuse infiltration. This tool will need further development and validation on pictures taken by different categories of common health care workers using available mobile phones.

Dietary Immunomodulators - An Organic Boom in the Management of Chronic Diseases

Immunology involves all the defence mechanisms occurring in the body after the invasion of any infectious agent and the ability to resist this infection. The micronutrients like essential proteins, essential amino acids, vitamins (A, B6, B12, C, D, E and folic acid), fatty acids, minerals (iron, selenium, zinc and copper) and certain phytochemicals are of prime importance towards healthy immune system. In addition to these nutritional components, intestinal microflora and certain bacteria (probiotic bacteria) also play an important role in the modulation of healthy immune system. There is an ongoing trend of usage of immunomodulators to combat various chronic diseases like viral diseases, cancers, inflammatory and autoimmune diseases. This review focuses on various immunomodulators available in daily dietary meals, its positive and negative effects on immune system and its role in management of chronic illness as an adjunct to other modalities to achieve positive health benefits with minimal side effects.

Motivation and counselling regarding the adverse effects of smartphone usage is should be given the utmost priority. Generating awareness among parents at the community level through field health workers is also the need of the hour.

Six-minute walk test for assessment of work capability in patients with chronic obstructive pulmonary disease: A cross-sectional comparative study

Background: Chronic obstructive pulmonary disease (COPD) is a systemic disorder causing morbidity, disability, and mortality throughout the world. Although, spirometry parameters have been used for decades to diagnose COPD as well as to grade the severity of this disease, others factors such as the BMI, degree of inflation, and exercise capacity have become important outcome measures for extra-pulmonary manifestations. The 6-min walk test (6MWT) is considered as a simple test to assess the functional capacity of COPD patients. The aim of our study was to implement 6MWT in patients of COPD in our setup to predict morbidity. Aims and Objectives: The objective of our study was to implement 6MWT in patients of COPD in our setup to predict morbidity. Materials and Methods: A cross-sectional comparative study was conducted on thirty COPD patients and thirty control subjects. All the subjects were investigated through history taking, clinical examination, spirometry, and 6MWT in the Department of Physiology, R.G. Kar Medical College and Hospital, Kolkata. Statistical analysis was done by SPSS version-21. Results: The values of the spirometry parameters were significantly reduced in cases than in the controls (P < 0.05). The values of 6-min walk distance as well as 6-min work (6MWORK) were also significantly reduced in cases than in the controls (P = 0.0023 and P = 0.0028, respectively). A strong positive correlation was found between forced vital capacity and 6MWORK (r = 0.556), BMI, and 6MWORK (r = 0.84) in patients of COPD. Conclusion: Our study substantiates that 6MWT can be implemented in our set up to assess the work capability and thus to predict morbidity in patients of COPD.

Predictors of Poor Outcome in Patients with COVID-19 associated Respiratory Failure: A Retrospective Observational Study

Background: Coronavirus disease 2019 (COVID-19) is majorly known to cause mild to moderate disease, but a small fraction of patients may develop respiratory failure due to diffuse lung injury, requiring management in the intensive care unit (ICU). This study attempts to identify factors that can predict unfavorable outcomes in moderate to severe COVID-19 patients. Methods: Hospital records of 120 COVID-19 patients admitted to the ICU were retrospectively analyzed and data pertaining to demographic, clinical, and laboratory parameters were obtained. These data were then compared with outcome parameters like survival, duration of hospital stay, and various adverse events. Results: Out of 120 patients, 70% were male, with a mean age of 54.44 years [standard deviation (SD) ± 14.24 years]. Presenting symptoms included breathlessness (100%), cough (94.17%), fever (82.5%), and sore throat (10.83%). Diabetes, hypertension, and chronic obstructive pulmonary disease (COPD) were the common comorbidities associated. Increased serum D-dimer, ferritin, interleukin-6 (IL-6) levels, and unvaccinated status were associated with higher mortality. Overall, 25.83% of patients survived, 24.41% of patients developed septic shock, and 10.6% of patients were discharged on oxygen. World Health Organization (WHO) clinical progression scale score ? 6 had 57 and 82% sensitivity and 83 and 77% specificity on days 7 and 14 after admission, respectively, for predicting mortality. A baseline National Early Warning Score 2 (NEWS 2) ? 9 had 48% sensitivity and 88% specificity for predicting mortality. Conclusion: Advanced age and associated comorbidities are linked to adverse outcomes in moderate to severe COVID-19. Persistently high D-dimer levels, despite standard treatment, may also contribute to increased mortality. WHO clinical progression scale and NEWS 2 have high specificity for predicting mortality.

Single-nucleotide polymorphism and haplotype analysis of macrophage migration inhibitory factor gene and its correlation with serum macrophage migration inhibitory factor levels in North Indian psoriatic patients with moderate disease severity: A cross-sectional study

Background: Psoriasis is associated with significant morbidity and impaired quality of life. Identification of the host genes that influence disease susceptibility and can potentially guide future, targeted therapy is the need of the hour. Aims: The aim of the study was to investigate the associations of macrophage migration inhibitory factor (MIF) gene polymorphisms, that is, a 5–8-CATT tetra nucleotide repeats at -794 (-794*CATT5–8) and a single-nucleotide polymorphism at -173 (-173*G/C) with the risk of chronic plaque psoriasis and to observe the correlation, if any, of disease determinants with genetic functional variants and circulating MIF levels. Methods: Five hundred and seventeen individuals (265 psoriasis patients and 252 controls) were genotyped for MIF gene polymorphisms. Data were analyzed with respect to disease susceptibility, serum MIF levels, disease severity, age at onset, disease duration and presence of comorbidities. Results: The presence of co-morbidities was more frequently noted in patients with late onset disease (P = 0.01). No statistically significant differences were observed either in genotype (P = 0.680) or allele frequency (P = 0.69) with respect to distribution of MIF-173*G/C polymorphism between patients and controls. The frequencies of genotypes -794*CATT 5/7 and 7/7 were significantly lower in patients (P = 0.027* and 0.038*, respectively). CATT*5/MIF-173*C haplotype occurred at a higher frequency in patients (odds ratio 3.03, 95% confidence intervals 1.09–8.47, P = 0.02). The mean serum MIF levels were significantly higher in patients as compared to controls (P < 0.001). The presence of either extended MIF -794*CATT repeats or C allele did not reveal any significant association with serum MIF levels or age at onset. Analysis of effect of various disease determinants revealed no significant association with genetic variants and serum MIF levels. Limitations: The lesional expression of MIF could not be studied. Conclusion: Our results showed that CATT*5/MIF-173*C haplotype is associated with increased susceptibility to psoriasis vulgaris.

SGLT2 inhibitors and cardiovascular outcomes in heart failure with mildly reduced and preserved ejection fraction: A systematic review and meta-analysis

Aim: To provide a pooled effect of sodium-glucose cotransporter-2 inhibitors (SGLT2i) on cardiovascular outcomes in patients with heart failure with preserved ejection fraction (HFpEF: _x0001_50%) or/and mildly reduced EF (HFmrEF: 41e49%) regardless of baseline diabetes. Methods: We systemically searched PubMed/MEDLINE, Embase, Web of Science databases and clinical trial registries using appropriate keywords till August 28, 2022, to identify randomized controlled trials (RCTs) or post-hoc analysis of RCTs, reporting cardiovascular death (CVD) and/or urgent visits/hospitalization for heart failure(HHF) in patients with HFmrEF/HFpEF receiving SGLTi vs. placebo. Hazard ratios (HR) with 95% confidence intervals (CI) for outcomes were pooled together using generic inverse variance method with fixed-effects model. Results: We identified six RCTs, pooling data retrieved from 15,769 patients with HFmrEF/HFpEF. Pooled analysis showed that compared to placebo, SGLT2i use was significantly associated with improved CVD/ HHF outcomes in HFmrEF/HFpEF (pooled HR 0.80, 95% CI: 0.74, 0.86, p < 0.001, I 2 ¼ 0%). When separately analyzed, benefits of SGLT2i remained significant across HFpEF (N ¼ 8891, HR 0.79, 95% CI: 0.71, 0.87, p < 0.001, I 2 ¼ 0%) and HFmrEF (N ¼ 4555, HR 0.77, 95% CI: 0.67, 0.89, p < 0.001, I 2 ¼ 40%). Consistent benefits were observed also in HFmrEF/HFpEF subgroup without baseline diabetes (N ¼ 6507, HR 0.80, 95% CI: 0.70, 0.91, p < 0.001, I 2 ¼ 0%). Sensitivity analysis including the DELIVER and EMPEROR-Preserved trials found a trend towards significant beneficial effects on CV deaths with no heterogeneity (HR 0.90, 95% CI: 0.79, 1.02, p ¼ 0.08, I 2 ¼ 0%). Conclusions: This meta-analysis established the place of SGLT2i as a foundational therapy among patients with HF with preserved and mildly reduced EF regardless of diabetes.

Visual impairment and blindness due to retinitis pigmentosa in India: 15-year follow-up of the Andhra Pradesh Eye Disease Study cohort

Purpose: To assess the incidence, visual impairment, and blindness due to retinitis pigmentosa (RP) in a rural southern Indian cohort. Methods: This is a population?based longitudinal cohort study of participants with RP from the Andhra Pradesh Eye Disease Study (APEDS) cohorts I and III, respectively. The study included participants with RP of APEDS I who were followed until APEDS III. Their demographic data along with ocular features, fundus photographs, and visual fields (Humphrey) were collected. Descriptive statistics using mean ± standard deviation with interquartile range (IQR) were calculated. The main outcome measures were RP incidence, visual impairment, and blindness as per the World Health Organization (WHO) definitions. Results: At baseline (APEDS I), 7771 participants residing in three rural areas were examined. There were nine participants with RP with a mean age at baseline of 47.33 ± 10.89 years (IQR: 39–55). There was a male preponderance (6:3), and the mean best?corrected visual acuity (BCVA) of 18 eyes from nine participants with RP was 1.2 ± 0.72 logarithm of minimum angle of resolution (logMAR; IQR: 0.7–1.6). Over a mean follow?up duration of 15 years, 5395/7771 (69.4%) were re?examined, which included seven RP participants from APEDS 1. Additionally, two new participants with RP were identified; so, the overall incidence was 370/ million in 15 years (24.7/million per year). The mean BCVA of 14 eyes of seven participants with RP who were re?examined in APEDS III was 2.17 ± 0.56 logMAR (IQR: 1.8–2.6), and five of these seven participants with RP developed incident blindness during the follow?up period. Conclusion: RP is a prevalent disease in southern India that warrants appropriate strategies to prevent this condition.

Study of heart rate variability to assess autonomic dysfunction in patients with chronic obstructive pulmonary disease of a tertiary care hospital of West Bengal: A cross-sectional comparative study

Background: Chronic obstructive pulmonary disease (COPD) is one of the major causes of morbidity and mortality throughout the world. COPD and its complications also lead to a large number of deaths every year in our country. Cardiac arrhythmias and sudden cardiac death are the major complications of COPD leading to death and disability. Such cardiac complications are often a result of autonomic dysfunction. Aims and Objectives: This study aims to find out the autonomic dysfunction in moderate COPD patients by comparing their heart rate variability (HRV) parameters with age and sex matched healthy controls. Materials and Methods: After obtaining approval from the Institutional Ethics Committee, 48 patients of moderate COPD and 54 healthy subjects were assessed and compared with respect to their HRV parameters which included Mean RR, Mean HR, SDNN, NN50, pNN50, root mean square of successive differences (RMSSD), high frequency (HF), low frequency (LF), LF/HF ratio, and SD2/SD1 ratio. Results: It was found that in comparison to healthy controls, patients of moderate COPD had significant alteration in the following HRV parameters – Mean HR (P: 0.001), RMSSD (P: 0.002), SDNN (P: 0.015), NN50 (P: 0.001), pNN50 (P: 0.000), HF (NU/normalized unit) [P: 0.033], HF (%) [P: 0.002], LF (NU/normalized unit) [P: 0.033], LF (%) [P: 0.012], and LF/HF (P: 0.033). Conclusion: As there is a significant alteration of several HRV parameters in moderate COPD patients, we conclude that HRV measurement may subserve as a simple and non-invasive tool to assess autonomic dysfunction in patients of COPD at the earliest.

Optical coherence tomography-based assessment of macular vessel density, retinal layer metrics and sub-foveal choroidal thickness in COVID-19 recovered patients

Purpose: The primary objective of the study was to assess the macular retinal vessel density, subfoveal choroidal thickness, and retinal layer metrics by optical coherence tomography angiography (OCTA), enhanced?depth imaging optical coherence tomography (EDI?OCT), and spectral domain optical coherence tomography (SD?OCT), respectively, in recovered COVID?19 patients and its comparison with the same in control subjects. The secondary objective was to evaluate differences in OCTA parameters in relation with the severity of COVID?19 disease and administration of corticosteroids. Methods: A case–control study was performed that included patients who had recovered from COVID?19 and age?matched healthy controls. Complete ocular examination including OCTA, SD?OCT, and EDI?OCT were performed three months following the diagnosis. Results: Three hundred sixty eyes of 180 subjects were enrolled between the two groups. A decreased mean foveal avascular zone area in both superficial capillary plexuses (P = 0.03) and deep capillary plexuses (P < 0.01), reduced average ganglion cell layer?inner plexiform layer thickness (P = 0.04), and increased subfoveal choroidal thickness (P < 0.001) were observed among cases in comparison to the control group. A significant correlation was found between sectoral macular vessel density in relation to disease severity and a decrease in vessel density with greater severity of the disease. Conclusion: OCTA detected retinal microvascular alterations following SARS?CoV?2 infection in subjects with the absence of any clinical ocular manifestation or systemic thrombotic events. These parameters could be used to help identify patients with a higher incidence of systemic thromboembolism on longer follow?ups and identify the impact of corticosteroids on retinal architecture.

A hospital-based study on COVID-19 patients with rhino-orbital mucormycosis

Coronavirus diseases 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 virus produce opportunistic fungal infections. Mucormycosis is an acute onset rapidly progressive fatal infection. Incidence of rhino-orbital mucormycosis raised during the second wave of COVID-19 pandemic in India. Diabetes, steroid therapy, cancer, prolonged hospitalization, and metabolic acidosis are the risk factors of post-COVID-19 mucormycosis. Objectives of this study were to suggest the risk factors, clinical features, investigations, and treatment of post-COVID-19 rhino-orbital mucormycosis. This study will guide the future research and the clinician will be aware about this complication of COVID-19. After getting permission from the Institutional Ethical Committee and consent from patients, we studied 10 cases of post-COVID-19 rhino-orbital mucormycosis from April to September 2021 during our duty in COVID-19 admission desk and COVID-19 ward in NRS Medical College, Kolkata. After taking history, we observed the clinical features, investigations, and treatment of the patients. Symptoms of the patients were nasal discharge, nasal block, headache, facial swelling, and blackish discoloration of skin. Most of the patients were diabetic. Magnetic resonance imaging (MRI)-PNS was showed sinonasal mass. Amphotericin-B was used and debridement was the main surgical procedure. Microscopy showed broad aseptate hyphae suggesting mucor. Early diagnosis and proper treatment will reduce the morbidity and mortality of the patient with post-COVID rhino-orbital mucormycosis.

Exposure to Electromagnetic Fields from Mobile Phones and Fructose consumption Coalesce to Perturb Metabolic Regulators AMPK/SIRT1-UCP2/FOXO1 in Growing Rats / 生物医学与环境科学（英文）

OBJECTIVE@#In this study, the combined effect of two stressors, namely, electromagnetic fields (EMFs) from mobile phones and fructose consumption, on hypothalamic and hepatic master metabolic regulators of the AMPK/SIRT1-UCP2/FOXO1 pathway were elucidated to delineate the underlying molecular mechanisms of insulin resistance.@*METHODS@#Weaned Wistar rats (28 days old) were divided into 4 groups: Normal, Exposure Only (ExpO), Fructose Only (FruO), and Exposure and Fructose (EF). Each group was provided standard laboratory chow ad libitum for 8 weeks . Additionally, the control groups, namely, the Normal and FruO groups, had unrestricted access to drinking water and fructose solution (15%), respectively. Furthermore, the respective treatment groups, namely, the ExpO and EF groups, received EMF exposure (1,760 MHz, 2 h/day x 8 weeks). In early adulthood, mitochondrial function, insulin receptor signaling, and oxidative stress signals in hypothalamic and hepatic tissues were assessed using western blotting and biochemical analysis.@*RESULT@#In the hypothalamic tissue of EF, SIRT1, FOXO 1, p-PI3K, p-AKT, Complex III, UCP2, MnSOD, and catalase expressions and OXPHOS and GSH activities were significantly decreased ( P < 0.05) compared to the Normal, ExpO, and FruO groups. In hepatic tissue of EF, the p-AMPKα, SIRT1, FOXO1, IRS1, p-PI3K, Complex I, II, III, IV, V, UCP2, and MnSOD expressions and the activity of OXPHOS, SOD, catalase, and GSH were significantly reduced compared to the Normal group ( P < 0.05).@*CONCLUSION@#The findings suggest that the combination of EMF exposure and fructose consumption during childhood and adolescence in Wistar rats disrupts the closely interlinked and multi-regulated crosstalk of insulin receptor signals, mitochondrial OXPHOS, and the antioxidant defense system in the hypothalamus and liver.

Corneal confocal microscopy identifies structural small fibre abnormalities in an adolescent with type 1 diabetes and impaired awareness of hypoglycaemia / Journal of the ASEAN Federation of Endocrine Societies

@#Impaired awareness of hypoglycaemia (IAH) is present in around 25-40% of individuals with type 1 diabetes mellitus (T1DM). Herein, we present a case of an adolescent with T1DM and IAH who had worse corneal nerve parameters compared to a T1DM adolescent without IAH. Small fibre abnormalities detected by corneal confocal microscopy in an objective easy-to-perform non-invasive test might be a surrogate indicator of underlying autonomic dysfunction in T1DM and IAH.
