Predictors of Control Status of Hypertension in India: A Systematic Review and Meta-analysis.

Predictors of hypertension (HTN) control status have not been well understood in India. This information is crucial for policymakers and program managers to devise newer HTN control strategies and implement relevant policies and programs. Therefore, we undertook this meta-analysis to estimate the effect of various factors on the control status of HTN in India. We systematically searched PubMed and Embase for observational studies and community-based trials published between April 2013 and March 2021 conducted among people (≥ 15 years) with hypertension in India. Quality of studies was assessed using Newcastle Ottawa (NO) scale. Meta-analysis was performed using random effects model. We reported the effect of various factors on the prevalence of controlled HTN using pooled odds ratio (OR) with 95% confidence interval (CI). Of the 842 studies screened, we analyzed nine studies that included 2,441 individuals. Based on the NO scale, majority (90%) of studies had a low risk of bias. The odds of having controlled HTN were significantly higher among women (OR 1.78, 95% CI 1.62-1.95), those aged > 45 years (OR 1.69, 95% CI 1.44-1.97), and those residing in urban parts of India (OR 1.74; 95% CI 1.48-2.03). These measures varied considerably across different regions of the country. Very few studies reported data on the relationship between behavioural risk factors of non-communicable diseases (NCDs) and HTN control status. We did not find any statistically significant differences between behavioural risk factors of NCDs and HTN control status. To improve HTN control in India, the ongoing/newer HTN control programs need to target men, those aged 15-45, and rural residents. Future studies on HTN control determinants should report disaggregated data and use standardized definitions for behavioral risk factors to enhance reliability and comprehensiveness of findings on the determinants of HTN control in future reviews.

Synthesis, characterization, crystal structure and cytotoxic properties of thiosemicarbazide Ni(II) and Zn(II) complexes.

Synthesis of new complexes of Ni(II) (1) and Zn(II) (2) with [1-(2-hydroxy-3,5-diiodobenzylidene)-4-phenylthiosemicarbazide] have been reported. The composition of these two complexes 1 and 2 is discussed on the basis of IR, (1)H NMR and UV spectral data along with their X-ray crystallographic data. The crystal structure of these two complexes has revealed that the free ligand (L) is deprotonated twice at the oxygen and sulfur atoms and they are coordinated with the complexes through phenoxide-O, azomethine-N and thiolate-S atoms. The single-crystal X-ray structures of complex (1) exhibits a square planar structure, while complex (2) reveals trigonal bipyramidal distorted square based pyramidal structure. Anticancer activity of ligand and the complexes 1-2 are evaluated in human adenocarcinoma (MCF-7) cells. The preliminary bioassay indicates that the free ligand and the complexes 1-2 exhibit inhibitory activity against the human adenocarcinoma cancer cell lines.

Synthesis and spectral characterization of Schiff base complexes of Cu(II), Co(II), Zn(II) and VO(IV) containing 4-(4-aminophenyl)morpholine derivatives: antimicrobial evaluation and anticancer studies.

Metal(II) chelates of Schiff bases derived from the condensation of 4-morpholinoaniline with substituted salicylaldehyde have been prepared and characterized by (1)H NMR, IR, electronic, EPR, and magnetic measurement studies. The complexes are of the type M(X-MPMP)2 [where M=Cu(II), Co(II)), Zn(II), or VO(IV); MPMP=2-[(4 morpholinophenyl imino) methyl] 4-X-phenol, X=Cl, (L1H), X=Br (L2H)]. Single crystal X-ray crystallography studies confirm the structure of newly synthesized Schiff bases. The Schiff bases act as bidentate monobasic ligands, coordinating through deprotonated phenolic oxygen and azomethine nitrogen atoms. The free ligands and metal complexes are screened for their biopotency. Metal complexes exhibit better activity than ligands. Anticancer activity of ligands and their metal complexes are evaluated in human heptocarcinoma(HepG2) cells. The preliminary bioassay indicates that the Schiff base and its zinc complex exhibit inhibitory activity against the human gastric cancer cell lines.

In vitro evidence for chronic alcohol and high glucose mediated increased oxidative stress and hepatotoxicity.

BACKGROUND: Hyperglycemia or alcoholism can lead to impaired liver functions. Cytochrome P450 2E1 (CYP2E1) is elevated in hyperglycemia or alcoholism and plays a critical role in generating oxidative stress in the cell. METHODS: In the present study, we have used VL-17A cells that overexpress the alcohol metabolizing enzymes [alcohol dehydrogenase (ADH) and CYP2E1] to investigate the toxicity due to ethanol (EtOH) plus high glucose. Toxicity was assessed through viability assay and amount of acetaldehyde adduct formation. Oxidative stress parameters included measuring reactive oxygen species (ROS) levels and malondialdehyde adduct formation. Apoptosis was determined through caspase-3 activity, Annexin V- Propidium iodide staining, and changes in mitochondrial membrane potential. The effects of antioxidants and specific inhibitors of ADH and CYP2E1 on cell viability and ROS levels were also studied. RESULTS: When present together, EtOH plus high glucose-treated VL-17A cells exhibited greater oxidative stress and toxicity than other groups. Apoptosis was observed in liver cells treated with the toxins, and the EtOH plus high glucose-treated VL-17A cells exhibited apoptosis to the largest extent. A distinct and graded increase in CYP2E1 level occurred in the different groups of VL-17A cells. Further, antioxidants or inhibitors of ADH and CYP2E1 were effective in decreasing the observed oxidative stress and toxicity. CONCLUSIONS: The combined oxidative insult due to alcohol plus high glucose leads to greater liver injury, which may prove to be a timely warning for the injurious effects of alcohol consumption in diabetics.
