Illiterate Addenbrooke's Cognitive Examination-III in Three Indian Languages: An Adaptation and Validation Study.

BACKGROUND: Literacy is an important factor that predicts cognitive performance. Existing cognitive screening tools are validated only in educated populations and are not appropriate for older adults with little or no education leading to poor performance on these tests and eventually leading to misdiagnosis. This challenge for clinicians necessitates a screening tool suitable for illiterate or low-literate older individuals. OBJECTIVES: The objective was to adapt and validate Addenbrooke's Cognitive Examination-III (ACE-III) for screening general cognitive functions in illiterate and low-literate older populations in the Indian context in three languages. METHOD: The Indian illiterate ACE-III was systematically adapted by modifying the original items of the Indian literate ACE-III to assess the cognitive functions of illiterates and low-literates with the consensus of an expert panel of professionals working in the area of dementia and related disorders. A total of 180 illiterate or low-literate participants (84 healthy-controls, 50 with dementia, and 46 with mild cognitive impairment [MCI]) were recruited from three different centers speaking Bengali, Hindi, and Kannada to validate the adapted version. RESULTS: The optimal cut-off score for illiterate ACE-III to distinguish controls from dementia in all 3 languages was 75. The optimal cut-off scores in distinguishing between controls and MCI ranged from 79 to 82, with a sensitivity ranging from 93% to 99% and a specificity ranging from 72% to 99%. CONCLUSION: The test is found to have good psychometric properties and is a reliable cognitive screening tool for identifying dementia and MCI in older adults with low educational backgrounds in the Indian context.

Association of common variants of TCF7L2 and PCSK2 with gestational diabetes mellitus in West Bengal, India.

The genetic etiology of gestational diabetes mellitus (GDM) was suggested to overlap with type-2 diabetes(T2D). Transcription factor 7-like 2 (TCF7L2) and Proprotein Convertase Subtilisin/Kexin type 2 (PCSK2) are T2D susceptibility genes of the insulin synthesis/processing pathway. We analyzed associations of TCF7L2 and PCSK2 variants with GDM risk and evaluated their potential impact on impaired insulin processing in an eastern Indian population. The study included 114 GDM (case) and 228 non-GDM pregnant women (control). rs7903146, rs4132670, rs12255372 of TCF7L2, and rs2269023 of PCSK2 were genotyped by PCR-RFLP, and genotype distributions were compared between case and control. Fasting serum proinsulin and C-peptide levels were measured by ELISA and the Proinsulin/C-peptide ratio was considered an indicator of proinsulin conversion. Significantly higher frequency of risk allele (T) of rs12255372 (p = 0.02, OR = 2.0, 95%CI = 1.11-3.64) and rs4132670 (p = 0.002, OR = 2.26, 95%CI = 1.32-3.87) of TCF7L2 was found in GDM cases than non-GDM controls; TT genotype was associated with significantly increased disease risk. In rs7903146 (TCF7L2) and rs2269023 (PCSK2), although the frequency of risk allele (T) was not significantly higher in cases than controls, an association of TT for both variants remained significant with higher GDM risk in the recessive model. Increased serum pro-insulin and proinsulin:c-peptide ratio was found in GDM than non-GDM women and the phenomenon showed significant association with careers of risk alleles for TCF7L2 variants. In conclusion, TCF7L2 and PCSK2 variants are related to GDM risk in the studied population and hence may serve as potential biomarkers for assessing the disease risk. TCF7L2 variants contribute to impaired insulin processing.

Health status of persons with dementia and caregivers' burden during the second wave of COVID-19 pandemic: an Indian study / Estado de saúde de pessoas com demência e sobrecarga dos cuidadores durante a 2ª onda da pandemia de covid-19: um estudo indiano

ABSTRACT. Due to the disruption of normal flow of treatment during the restrictions related to the coronavirus disease 2019 (COVID-19) pandemic, the health status of persons with dementia (PwD) and their caregivers' burden might worsen. Objective: The article aims to find out the health status of PwD and caregivers' burden during the peak of second wave of COVID-19 and make a comparison with the preceding trough phase. Methods: The study was conducted with 53 PwD and their caregivers in two phases. On their visit to the hospital during the unlock phase (phase 1), data were collected for CDR from PwD, and NPI-Q and ZBI from their caregivers. During the peak of second wave (phase 2), data were collected for NPI-Q, ZBI, and DASS-21 through telephonic communication, and statistical analyses were performed on the collected data. Results: Significantly higher caregiver burden (p=0.001) and neuropsychiatric symptoms (NPSs) [both in severity (p=0.019) and distress (p=0.013)] were observed among the respondents during the peak of second wave of the pandemic as compared to the preceding trough phase. Positive correlations were observed between the caregiver burden and depression, anxiety, and stress of the caregivers (p<0.001) and between the severity of dementia in PwD and caregiver burden (p<0.001) for both the first and second phases. Positive correlation was also observed between the severity of dementia in PwD and depression (p=0.042) and stress (p=0.023) of caregivers. Conclusions: Significant increase in the burden and distress was observed among caregivers due to increased NPSs of PwD during the second wave of COVID-19 pandemic.

Adaptation and Validation of Addenbrooke's Cognitive Examination-III in Bengali for Screening MCI and Dementia.

OBJECTIVE: Bengali, the 6th most spoken language globally with 268 million speakers, demands a culturally appropriate tool for screening any cognitive compromise in this population. Addenbrooke Cognitive Examination-III (ACE-III) is a standardized tool used for screening and/or diagnostic purpose worldwide. The aim of the present study was to adapt and validate ACE-III into Bengali language. METHODS: The ACE-III UK Version A (2012) was adapted with linguistically and culturally appropriate items and validated on Bengali speakers. The participants consisted of 40 dementia and 22 Mild Cognitive Impairment (MCI) patients and 120 healthy-controls. Reliability and validity were examined. Discriminant function analysis was done. Sensitivity and specificity were evaluated and optimum cut-offs were established for MCI and dementia. RESULTS: Both sensitivity and specificity of ACE-III-Bengali of identifying dementia was 1; sensitivity for MCI ranged from 0.83 to 1, specificity from 0.76 to 1. Discriminant function analysis showed a significant difference in all domains of ACE-III-Bengali between healthy individuals and persons with neurocognitive impairment. Separate optimum ACE-III-Bengali cut-off scores were established according to level of education. For low education (

Exploring Caregiver Burden and Health Condition of Dementia Patients during Lockdown due to COVID-19 Pandemic.

Background: To combat the COVID-19 pandemic, several countries imposed strict lockdown to ensure social distancing to limit the spread of the virus. This caused difficulties in the management and care of patients with various chronic disorders including dementia. Objectives: The objective of the study was to explore the health condition of patients with dementia and assess their caregivers' burden during the lockdown. Methods: A total of 57 caregivers of patients with dementia who had attended the cognitive clinic of the institute for a follow-up within 1 year preceding the lockdown were assessed through telephonic interviews. Caregivers' details were noted following an interview related to the patients' health condition during lockdown and caregiver concerns. Results: Findings showed a deterioration in memory in 66.7% of patients with dementia and an increase in symptoms like agitation, sleeplessness, low mood, restlessness, aggression, etc., Caregivers felt helpless and had to manage new concerns and they were not sure as to how to deal with the situation. Conclusion: The lockdown situation disrupted the health conditions of dementia patients and caregivers faced novel challenges while managing them.

Visualizing the efficacy of vaccination in different Indian states: a comparative account with other countries.

Efficacy of the vaccination program for COVID-19 pandemic caused by SARS-CoV-2 (Severe Acute Respiratory Syndrome-CoronaVirus-2) was analyzed. The data for number of cases and vaccination, obtained from government websites from 1st January, 2020 to 10th October, 2021 for India, USA, United Kingdom, Italy, South Africa and states West Bengal, Delhi, Maharashtra, Kerala and Tamil Nadu. Modified Poisson prediction models were developed using SPSS to predict the number of cases with and without vaccination as predictor to catalogue the efficacy of vaccination. In the prediction model where vaccination was used as a predictor, the downward trend of predicted value matched with actual value, falling within the 95% confidence interval. However, individual peaks of waves were not observed clearly for the predicted values. Vaccination within the population was observed to be very critical in controlling the pandemic progression with all countries showing decrease in daily case counts as more people in the population got vaccinated. In India, owing to the huge population, more vaccination is needed for the predicted cases to fall lower.

Revisiting anatomical variants on screening chest radiographs in Indian adolescents: A cross sectional observational pilot study.

BACKGROUND: Knowledge of normal variation and measurements on a chest radiograph is essential to interpret any abnormality. There is paucity of information about normal measurement ranges and variations in young adolescents, particularly from Indian subcontinent. The aim of this study was to analyze certain normal variations on screening chest radiographs of healthy Indian adolescents and the objectives were to measure/assess (1) degree of inspiration, (2) cardiothoracic ratio (CTR), (3) presence of gastric fundic bubble, (4) fundocupolic distance, (5) presence of splenic flexure, (6) difference in height of diaphragmatic domes and (7) effect of inspiration on the CTR. METHODS: Digital chest radiographs obtained during routine medical examinations for all consecutive medical graduate aspirants in the year 2016 at a medical college, were analyzed for the above mentioned parameters using DICOM viewing software. RESULT: A total of 558 chest radiographs were analyzed. The mean age of the subjects was 18.50 (SD = 1.002) (range: 17-22 years). There were 497 (89.1%) male and 61 (10.9%) female. Degree of inspiration was at 5th, 6th, 7th and 8th ribs in 29 (5.1%), 259 (46.4%), 264 (47.3%) and 6 (1%) respectively. Mean maximum transverse cardiac diameter, internal thoracic diameter, CTR were 1153.22 ± 120.01, 2935.24 ± 224.86 and 0.39 ± 0.03 respectively. Females had slightly higher CTR (0.40 ± 0.035) as compared to the males (0.39 ± 0.032) (p = 0.009). Gastric fundic bubble was visualized in 91% subjects. Mean fundo-cupolic distance was 8.75 ± 8.00. Mean value for difference in the level of two domes of diaphragm was 15.28 ± 5.38. CONCLUSION: The study highlights normal range of inspiration, CT ratio, fundocupolic distance and diaphragmatic dome level difference on screening chest radiographs in healthy Indian adolescents.

Bhattachar, Sagarika Patyal, and Rajan Grewal. High-altitude pulmonary edema management: Is anything other than oxygen required? Results of a randomized controlled trial. High Alt Med Biol. 17:294-299, 2016.-Treatment strategies for management of high-altitude pulmonary edema (HAPE) are mainly based on the observational studies with only two randomized controlled trials, thus the practice is very heterogeneous and individualized as per the choice of treating physician. To compare the response to different modalities of therapy in patients with HAPE in a randomized controlled manner. We conducted an open-label, randomized noninferiority trial to compare three modalities of therapy (Therapy 1: supplemental O2 with oral dexamethasone 8 mg q8 hours [n = 42], Therapy 2: supplemental O2 with sustained release oral nifedipine 20 mg q8 hours [n = 41], and Therapy 3: only supplemental O2 [n = 50]). Bed rest was mandated in all patients. The study was conducted in a cohort of previously healthy young lowlander males at an altitude of 3500 m. Baseline characteristics of the patients were comparable in the study arms. Complete response was defined as clinical and radiological resolution of features of HAPE, no oxygen dependency, a normal 6-minute walk test (6MWT) on 2 consecutive days, and normal two-dimensional echocardiography. Results were compared by analysis of variance using SPSS version 16.0. There was no statistical difference in duration of therapy to complete response between the three groups (Therapy 1: 8.1 ± 4.0 days, Therapy 2: 6.7 ± 3.9 days, Therapy 3: 6.8 ± 3.2 days; p = 0.15). There were no deaths in any of the groups. We conclude that oxygen and bed rest alone are adequate therapy for HAPE and that adjuvant pharmacotherapy with either dexamethasone or nifedipine does not hasten recovery.

Design and synthesis of caffeoyl-anilides as portmanteau inhibitors of HIV-1 integrase and CCR5.

Designing multi-functional ligands is a recent strategy by which multiple targets can be inhibited by a single entity. A series of caffeoyl-anilide compounds based on structures of various integrase and CCR-5 inhibitors have been designed and synthesized as anti-HIV agents in the present study. Most of the compounds exhibited potent anti-HIV activity at micromolar concentration in CEM-GFP CD4+ T cells infected with HIV-1NL4.3 virus. Compound 14 showed a lower EC(50) and better TI as compared to AZT. Mechanism based studies suggest that these compounds inhibit either one or in some cases, both the targets. The experimental data and the docking results showed that these compounds are potential inhibitors for both HIV-1 IN and CCR5.
