RESUMO

INTRODUCTION: Thyroid hormones have a major influence on synthesis, mobilization and metabolism of lipids. Hypothyroidism accounts for a notable cause of secondary dyslipidemia. This can increase the risk for cardiovascular morbidity and mortality. This study was performed to find out the prevalence of lipid profile abnormalities in newly diagnosed primary hypothyroid states. METHODS: This descriptive cross-sectional study was conducted among 71 patients in the context of newly diagnosed primary hypothyroidism patients visiting outpatient department of internal medicine from 9th December 2018 to 30th June 2020 after taking ethical clearance from Institutional Review Committee. Case screening for lipid profile changes was performed at the time of diagnosis of primary hypothyroidism. A convenience sampling method was used. Data entry and descriptive analysis were done in Statistical Package for the Social Sciences version 16.0. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: In this study including 71 cases of newly diagnosed primary hypothyroidism, 49 (69.0%) (95% Confidence Interval= 58.24-79.76) had abnormal lipid profiles. Among them, 5 (38.5%) out of 13 (18.3%) cases of subclinical hypothyroidism and 44 (75.9%) out of 58 (81.7%) cases of overt hypothyroidism had abnormal lipid profiles. CONCLUSIONS: The prevalence of abnormal lipid profile parameters was similar to the study done in various studies in similar settings except for high-density lipid which showed both similarity and dissimilarity with other studies. Our study suggested that all newly diagnosed cases of primary hypothyroidism are to be investigated for dyslipidemia thus ensuring early treatment and prevention of complications.

RESUMO

INTRODUCTION: D-dimer is currently the best available marker for COVID-19 associated hemostatic abnormalities. This study aims to find out the prevelance of elevated D-dimer levels in confirmed COVID-19 cases in intensive care unit of a tertiary care hospital of western Nepal. METHODS: This descriptive cross-sectional study was conducted among 95 patients admitted to COVID Intensive Care Unit of a teriary care centre from August 2020 to January 2021 after taking ethical clearence from Institutional Review Committee in order to determine the D-dimer levels in confirmed COVID-19 cases. D-dimer value was measured at the admission and the highest D-dimer value was recorded during the course of hospital stay with the risk of mortality in confirmed COVID-19 cases. The normal range of D-dimer was taken as <0.35 mg/dl as per our hospital laboratory standards. Convenience sampling method was used. Data entry and descriptive analysis were done in Statistical Package for the Social Sciences version 25.0, point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: Out of total 95 cases of COVID-19 included in this study, 25 (89.3%) patients with age ≥ 65 years and 42 (62.69%) patients aged <65 years had elevated D-dimer on admission. Data showed that 29 (67.4%) patients having elevated D-dimer at admission had mortality. CONCLUSIONS: Elevated D-dimer levels was frequently seen in patients admitted in Intensive Care Unit with COVID-19. Our study suggested that measurement of D-dimer may guide in clinical decision making.

RESUMO

Selective hydrogenation of nitriles and alkynes is crucial considering the vast applications of reduced products in industries and in the synthesis of bioactive compounds. Particularly, the late 3d transition metal catalysts (manganese, iron, cobalt, nickel and copper) have shown promising activity for the hydrogenation of nitriles to primary amines, secondary amines and imines. Similarly, semihydrogenation of alkynes to E- and Z-alkenes by 3d metals is adequately successful both via the transfer hydrogenation and by using molecular hydrogen. The emergence of 3d transition metals in the selective synthesis of industrially relevant amines, imines and alkenes makes this protocol more attractive. Herein, we provide a concise overview on the late 3d transition metal-catalyzed hydrogenation of nitriles to amines and imines as well as semihydrogenation of alkynes to alkenes.

RESUMO

Regioselective C(2)-H difluoroalkylation of C-3 unsubstituted indoles with commonly available fluoroalkyl bromides is successfully achieved employing a simple nickel catalyst system, (DME)NiCl2 /Xantphos. This methodology shows excellent regioselectivity and exhibits a broad substrate scope. Various functional groups, such as -OMe, -F, and -Br, are tolerated on the indole backbone to give the difluoroalkylated products in moderate to good yields. Preliminary mechanistic findings demonstrate that the reaction is homogeneous in nature and involves a radical manifold. Synthetic utility of this nickel-catalyzed method is demonstrated by synthesizing melatonin receptor antagonist Luzindole derivative.
