RESUMO
Background: Neutralizing antibodies cocktail (casirivimab and imdevimab) has received emergency use authorization recommendation by Food and Drug Administration (FDA) and WHO for mild-to-moderate COVID-19 infection in specific high-risk groups. Antibodies cocktail has shown promising results in preventing progression to severe disease, but the real-world experience is still evolving. Herein, we present a retrospective analysis of 22 patients who were administered the antibodies cocktail between August 2021 and March 2022 at our tertiary care center. Methods: We conducted an observational retrospective analysis of clinicoradiological, inflammatory parameters, progression of the disease, and outcome among 22 mild and moderate COVID-19 patients treated with antibodies cocktail. Results: The mean age was 67.7 years (SD ± 18.3) and comprised of 13 males (59%), while 9 were females (40.9%). Nine (40.9%) patients were fully vaccinated with two doses, nine (40.9%) were partially vaccinated with one dose while four patients (18.2%) were unvaccinated, and the rest were unvaccinated. Diabetes and hypertension were the commonest comorbidities; hematological and solid organ malignancies were other comorbidities. Eight patients had radiological opacities consistent with COVID-19 pneumonia and had shown significant regression in four patients after the therapy. None of our patients required supplemental oxygen or progressed to severe acute respiratory distress syndrome. All patients were discharged in a stable condition within 6 days of the therapy. Conclusions: The neutralizing antibodies cocktail has shown encouraging results in our analysis in preventing progression to severe disease in patients with high-risk conditions.
RESUMO
Background: India is the epicenter of diabetes mellitus (DM). The relationship between COVID and DM in age/gender-matched non-diabetics has not been studied yet. The role of DM in predicting the disease severity and outcome in COVID patients might provide new insight for effective management. Methods: We conducted a prospective comparative study at a COVID care center from 25th April-31st May 2021. Among 357 severe-COVID patients screened, all consecutive diabetes (n-113) and age/gender-matched non-diabetes (n-113) patients were recruited. All diabetics and non-diabetics at admission were subjected to high resolution computed tomography (HRCT) chest and inflammatory markers (C-reactive protein (CRP), D-dimer, ferritin, interleukin-6 (IL-6), lactate dehydrogenase (LDH), Neutrophil-Lymphocyte Ratio (NLR)) before starting anti- COVID therapy. Statistical analysis was done using JMP 15·0 ver·3·0·0. Results: The prevalence of DM among the screened population (n-357) was 38·37%. The mean age of the study population was 61y with male preponderance (57%). There was no statistical difference in the HRCT-score or inflammatory markers in the two groups except for higher NLR (p-0·0283) in diabetics. Diabetics had significantly inferior overall survival (OS) (p-0·0251) with a 15d-OS of diabetics vs. non-diabetics being 58·87%, 72·67%, and 30d-OS of diabetics vs. non-diabetics being 46·76%, 64·61%, respectively. The duration of the hospital stay was not statistically different in the two groups (p-0·2). Conclusion: The mortality is significantly higher in severe-COVID patients with DM when compared to age/gender-matched non-diabetics. There was no significant difference in most inflammatory markers/CT at admission between the two groups.
RESUMO
BACKGROUND: Studies have linked vitamin D to risk factors for cardiovascular disease. Obesity is a potential confounder in these studies. This study examined the relationship of 25 (OH) cholecalciferol (25[OH] D3) with insulin resistance, blood glucose, and lipid profile in lean male adults. METHOD: We enrolled two hundred and thirty four military recruits before beginning of military training. Demographic and anthropometric data were collected from them. The participants underwent body mass composition analysis by dual energy X ray absorptiometry. Fasting samples were collected for measurement of blood glucose, lipid profile, 25(OH) D3, serum parathormone (PTH) and insulin. RESULTS: Vitamin D deficiency and insufficiency was found in 47.7% (107/224) and 31.6% (71/224) of participants, respectively. Using Pearson's correlation coefficient 25(OH) cholecalciferol and fasting blood glucose (FBG) were inversely correlated (p = 0.023). However, similar relation was not found between 25(OH) D3 and total cholesterol, triglycerides, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, homeostatic model assessment of insulin resistance and levels of PTH. On body composition analysis, there was no correlation of 25(OH) cholecalciferol with body mass index or fat mass index. CONCLUSION: This study showed that in lean young male population, 25(OH) cholecalciferol and FBG are inversely correlated but no association of 25(OH) D3 with other cardiometabolic risk factors could be demonstrated.
RESUMO
BACKGROUND: Vitamin D deficiency (VDD) is ubiquitous in the Indian subcontinent. VDD has been shown to impair muscle functions. However, the association of VDD with cardiorespiratory endurance is uncertain. Hence, we enrolled and supplemented vitamin D in military recruits with VDD with an aim to evaluate effect of supplementation on cardiorespiratory endurance and muscle strength. METHOD: We enrolled 90 military recruits with VDD and randomly allotted them to two groups equally. The group I received cholecalciferol granules 60,000 IU every fortnight for twelve weeks (cases), and the group II was observed as control. Muscle strength and cardiorespiratory endurance was assessed with a battery of tests (standing broad jump, bent arm hang test, 20 m shuttle run) at baseline and repeated at the end of training (nineteen weeks). Blood samples were collected for measurement of serum 25(OH)D and parathyroid hormone. RESULTS: In Group I and Group II, there was significant increase in 25(OH) D levels (25.8 ± 7.1 and 17.3 ± 3.5 ng/ml, respectively), and in VO2 max (9.8 ± 8.8 and 12.7 ± 8.6 ml/kg/min, respectively) compared with the baseline values. However, no significant change was observed in muscle strength after supplementation. There was no difference between the groups in VO2 max and muscle strength at baseline and at the end of training. CONCLUSION: Vitamin D supplementation did not improve muscle strength and cardiorespiratory endurance in military recruits with VDD. A significant rise in 25(OH) D was observed even in those not supplemented with vitamin D.
RESUMO
BACKGROUND: To study the number of patients with Type 2 Diabetes Mellitus who achieve the glycemic, blood pressure and LDL-Cholesterol targets as per American Diabetes Association, Standard of Care for Management of Diabetes. METHODS: Hundred patients of Type 2 Diabetes mellitus were recruited from December 2008 to January 2009 from an Endocrinology OPD of tertiary care hospital and followed up for six months. Glycosylated hemoglobin (HbA1c), blood pressure (BP) and LDL-Cholesterol (LDL) were estimated at baseline and prevalence of those at target (HbA1c <7%, BP < 130/80 mm Hg, LDL < 100 mg/dl) was documented and repeated at three and six months to monitor improvement in the number of patients at target and trend in improvement of individual parameters. RESULTS: The percentage of patients at target at baseline and six months for HbA1c was (45% vs. 55% p = 0.101), BP < 130/80 mm Hg (27% vs. 25%) and LDL <100 mg/dl (37% vs. 40% p = 0.386). All three parameters were at target in one patient and three patients at six months period. Mean values at baseline and six months of HbA1c 7.46% (95% CI 7.17-7.75) vs 7.21% (95% CI 6.9-7.52), Systolic BP 138 mm Hg (95% CI 135-141), Diastolic BP 86 mm Hg (95% CI 84-86) and LDL 114 mg/dl (95%CI 107-121) vs. 110 mg/dl (95%CI 105-116) did not show significant improvement (p for trend). CONCLUSION: Standards of care for HbA1c, blood pressure and LDL remains to be achieved in majority of the diabetic patients.
RESUMO
OBJECTIVES: Vitamin D deficiency (VDD) is a global problem. Not all patients with VDD have clinical manifestations or secondary hyperparathyroidism. We studied the interaction between serum 25-hydroxy vitamin D (25OHD), parathormone (PTH) and bone mineral density (BMD) in Indian adolescents and adults. DESIGN: Population survey. PATIENTS: A total of 1829 adolescents and 1346 adults aged 50 years and above were analysed in this study. MEASUREMENTS: Serum biochemistry, 25OHD, PTH and BMD were estimated. Subjects were grouped according to quartiles of serum PTH. VDD was defined as severe (25OHD ≤ 5 ng/ml), moderate (25OHD ≤ 10 ng/ml) and mild (25OHD ≤ 20 ng/ml) and secondary hyperparathyroidism (SHPT) when serum PTH levels >65 pg/ml. RESULTS: Only 30-40% of subjects with moderate and severe VDD, respectively, had SHPT. BMD decreased from Quartile 1 to Quartile 4 of PTH at all sites among adolescents and adults, with only a marginal decline in serum 25OHD levels between these quartiles. Further, within each PTH quartile, there was no difference in BMD according to categories of VDD. Analysing BMD in the different PTH quartiles, the PTH cut-offs beyond which BMD showed a significant decline, was 35 pg/ml in adolescents and 53 pg/ml in adults. CONCLUSIONS: Less than half of the subjects with VDD have SHPT. BMD levels start to decline at PTH values currently considered to be normal. These data suggest the need to redefine SHPT in different age groups keeping in mind the relationship between PTH and BMD. This may also influence the decision to supplement subjects with VDD.

RESUMO
OBJECTIVE: To determine rates of depression by dementia status in a statewide sample of nursing home admissions, and associations with medical comorbidity and physical functioning. METHODS: Trained interviewers obtained information from nursing home residents, staff, significant others, and medical records. RESULTS: A total of 22.3% were classified depressed in the nondemented status and 23.6% in the demented status. Depression status was significantly associated with more physical dependencies regardless of dementia status. In the nondemented, there was also a significant positive association with number of comorbidities. One interaction, dementia with comorbidity at the highest levels of comorbidity, was significant in looking at association with depression. CONCLUSION: There is significant depressive symptomatology in nursing home admissions, which is also associated with difficulty in physical function and with the number of medical comorbidities in the nondemented. Application of the two measures used in this study represents a strategy to assess depression in all nursing home residents.

Transcriptional dysregulation is a central pathogenic mechanism in Huntington's disease (HD); HD and transgenic mouse models of HD demonstrate down-regulation of specific genes at the level of mRNA expression. Furthermore, neuronal intranuclear inclusions (NIIs) have been identified in the brains of R6/2 mice and HD patients. One possibility is that NIIs contribute to transcriptional dysregulation by sequestering transcription factors. We therefore assessed the relationship between NIIs and transcriptional dysregulation in the R6/2 mouse, using double-label in situ hybridization combined with immunohistochemistry, and laser capture microdissection combined with quantitative real-time PCR. There was no difference in transcript levels of specific genes between NII-positive and NII-negative neurons. These results demonstrate that NIIs do not cause decreases in D2, PPE and PSS mRNA levels in R6/2 striatum and therefore are not involved in the down-regulation of these specific genes in this HD model. In addition, these observations argue against the notion that NIIs protect against transcriptional dysregulation in HD.

Genome-wide linkage analyses of schizophrenia have identified several regions that may harbor schizophrenia susceptibility genes but, given the complex etiology of the disorder, it is unlikely that all susceptibility regions have been detected. We report results from a genome scan of 166 schizophrenia families collected through the Department of Veterans Affairs Cooperative Studies Program. Our definition of affection status included schizophrenia and schizoaffective disorder, depressed type and we defined families as European American (EA) and African American (AA) based on the probands' and parents' races based on data collected by interviewing the probands. We also assessed evidence for racial heterogeneity in the regions most suggestive of linkage. The maximum LOD score across the genome was 2.96 for chromosome 18, at 0.5 cM in the combined race sample. Both racial groups showed LOD scores greater than 1.0 for chromosome 18. The empirical P-value associated with that LOD score is 0.04 assuming a single genome scan for the combined sample with race narrowly defined, and 0.06 for the combined sample allowing for broad and narrow definitions of race. The empirical P-value of observing a LOD score as large as 2.96 in the combined sample, and of at least 1.0 in each racial group, allowing for narrow and broad racial definitions, is 0.04. Evidence for the second and third largest linkage signals come solely from the AA sample on chromosomes 6 (LOD = 2.11 at 33.2 cM) and 14 (LOD = 2.13 at 51.0). The linkage evidence differed between the AA and EA samples (chromosome 6 P-value = 0.007 and chromosome 14 P-value = 0.004).

Wei and Hemmings [2000: Nat Genet 25:376-377], using 80 British parent-offspring trios, identified a number of NOTCH4 variants and haplotypes that showed statistically significant evidence of association to schizophrenia. Specifically, the 10 repeat allele of a (CTG)(n) marker and the 8 repeat allele of a (TAA)(n) marker demonstrated excess transmission to affected individuals; SNP21 and haplotypes SNP2-(CTG)(n) and SNP12-SNP2-(CTG)(n) also showed significant associations. In an attempt to replicate these findings, we tested for linkage and association between the same five markers used by Wei and Hemmings in 166 families collected from a multi-center study conducted by the Department of Veterans Affairs (DVA) Cooperative Study Program (CSP). The families include 392 affected subjects (schizophrenia or schizoaffective disorder, depressed) and 216 affected sibling pairs. The families represent a mix of European Americans (n = 62, 37%), African Americans (n = 60, 36%), and racially mixed or other races (n = 44, 27%). We identified moderate evidence for linkage in the pooled race sample (LOD = 1.25) and found excess transmission of the 8 (P = 0.06) and 13 (P = 0.04) repeat alleles of the (TAA)(n) marker to African American schizophrenic subjects. The 8 and 13 repeat alleles were previously identified to be positively associated with schizophrenia by Wei and Hemmings [2000: Nat Genet 25:376-377] and Sklar et al. [2001: Nat Genet 28:126-128], respectively.

BACKGROUND: Verbal and physical aggression are common behavior problems among nursing home residents with dementia. Depression among nursing home residents is also a common but underdiagnosed disorder. METHOD: Data collected on 1101 residents with dementia, newly admitted to a sample of 59 nursing homes across Maryland, were analyzed to determine if there was a relationship between depression and physical and verbal aggression. RESULTS: Residents with dementia who manifested physical or verbal aggression had a higher prevalence of depression than those without such behaviors (p<0.05). CONCLUSIONS: Our findings suggest that nursing home residents with aggressive behaviors should be screened for depression and treated.

The purpose of this study was to determine if religious preference and religiosity influenced choosing end of life treatments in medically ill geriatric patients. The sample consisted of 374 males 60 years of age or older, hospitalized on the acute medical service at the Baltimore Veterans Affairs Medical Center. Choices for end of life treatment preferences were CPR, medical ventilation, tube feeding and IV fluids within six different illness scenarios. Patients indicated how often they attended religious services, how much strength and comfort they got from religion and how religious they would describe themselves. Analyses of variance were performed using as the dependent variables the summation scores across the six scenarios of a willingness to undergo each of the four life saving procedures. The religious preference, race and religiosity scores served as the independent variables. Only tube feeding showed a significant (p<0.05) relationship, with Catholics less willing to undergo this procedure than other Christians. The same trend was found for the other life saving procedures, but was not statistically significant.
