RESUMO

BACKGROUND: Diabetes-related dyslipidemia is a multifaceted, complicated disorder characterized by an abnormal lipid profile in individuals with diabetes. The incidence of different types of dyslipidemia, however, was not a focus of prior investigations. The patients were characterized into three categories of dyslipidemia. Different patterns of dyslipidemia were combined into single dyslipidemia (7 patterns), mixed dyslipidemia (16 patterns), and triple dyslipidemia (4 patterns). METHODS: In this cross-sectional study, 586 people suffering from type 2 diabetes mellitus (T2DM) were included. We assessed the serum lipid profile and used log (TG/HDL-C) to determine the atherogenic index of plasma (AIP). Dyslipidemia was examined as a categorical variable, and the findings were presented as percentages and numbers. To compare categorical variables, we either utilized Fisher exact tests or Chi square tests. RESULTS: The study comprised of 586 T2DM patients, with 310 (52.9%) women and 276 (47.1%) men. Women have significantly higher hypertension (33.6%) as compared to men (23.2%). 18.94% (111) of patients were having coronary artery disease (CAD) history consisting of 12.28% (72) females and 6.66% (39) males, a difference which is statistically significant. 98.12% of total individuals had as a minimum of one lipid abnormality. 4.61% (27) of study subjects were having isolated dyslipidemia and 93.51% (548) had dual or triple pattern of dyslipidemia (mixed dyslipidemia). High AIP >0.24 (94.8%) was the most predominant trend of dyslipidemia. The dual combination of AIP (>0.24) and HDL (<50 mg/dL in Females and <40 mg/dL in Males) was found to be the most common pattern of mixed dyslipidemia (68.08%). The most prevalent trend of isolated dyslipidemia was found to be high AIP (>0.24), In patients with CAD history. Among the mixed dyslipidemia, the common pattern of dyslipidemia (71.17%) was the dual combination of high AIP (>0.24) and low HDL (<50 mg/dL women and <40 mg/dL males). The triple combination of TG (≥200 mg/dL) and HDL (<40 and <50 mg/dL) and LDL (≥100 mg/dL) was only found in females. CONCLUSION: In conclusion, dyslipidemia is highly prevalent in T2DM patients, with mixed dyslipidemia being the most common type observed in the community of Kashmir valley, India. High AIP was the most prevalent pattern in the current investigation.

RESUMO

INTRODUCTION: The surge in novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection leading to coronavirus disease-2019 (COVID-19) has overwhelmed the health system. To help health-care workers and policy makers prioritize treatment and to decrease the burden on health systems caused by COVID-19, clinical severity along with various clinico-biochemical parameters was evaluated by designing a cross-sectional study comprising 236 SARS-CoV-2-infected individuals from Kashmir Valley, India. METHODS: Briefly, real-time polymerase chain reaction (RT-PCR) was used for the confirmation of SARS-CoV-2 infection. The principles of spectrophotometry and chemiluminescent microparticle immunoassay (CMIA) were employed to estimate the levels of glucose, TSH, and 25-hydroxy vitamin D levels in serum of infected patients. RESULTS: A total of 236 patients infected with SARS-CoV-2 were taken for this cross-sectional study. Patients with COVID-19 had a male predominance (72.9 vs. 27.1%) and a higher prevalence of 25-hydroxy vitamin D deficiency (72.0 vs. 28.0%) with a mean 25-hydroxy vitamin D levels of 24.0 ± 13.9 in ng/mL. We observed a varied clinical spectrum of SARS-CoV-2 infection with 36.4%, 23.7%, and 29.7% patients having mild, moderate, and severe disease, respectively. We observed that severity of SARS-CoV-2 infection was significantly associated with older age group, hypertension, low TSH levels, and 25-hydroxy vitamin D deficiency. CONCLUSION: We conclude that not only old age but also hypertension and low levels of TSH and 25-hydroxy vitamin D levels could significantly lead to clinical severity of SARS-CoV-2 infection.

RESUMO

OBJECTIVE: The study aimed to evaluate the association of UCP2 gene polymorphism - 866 G/A and its expression with diabetes predisposition in the North Indian population. METHODS: The study involved 850 subjects, including 425 each T2DM and control subjects. The serum metabolic and clinical parameters were estimated using standard protocols. The PCR-RFLP based genotyping was performed to determine UCP2 gene polymorphism, while the expression was measured by real-time quantitative PCR. RESULTS: The genotypic and allelic frequencies showed a significant difference in cases compared to controls (p < 0.05). The diabetes patients had a 4.2-fold decrease in UCP2 gene expression. The expression was 29.8 and 8.4 fold lower in diabetes patients with homozygous (AA) and heterozygous (GA) mutation at - 866 locus of UCP2 nucleotide sequence, respectively. When categorized according to age and BMI, the T2DM subjects with age ≥ 50 and BMI ≥ 25 had a 5.53 and 8.2-fold decrease in UCP2 expression, respectively. The diabetes subjects with homozygous and heterozygous mutation demonstrated a pathological increase in serum metabolic and clinical parameters, which corroborated with UCP2 gene expression, indicating a strong association between the two. Intriguingly, we did not find any association between - 866 G/A polymorphism of UCP2 with serum insulin levels. CONCLUSION: Our investigation is the first among the studies conducted in Jammu and Kashmir to work on adipose tissue and UCP2 gene polymorphism. The association of - 866 G/A SNP of the UCP2 gene with its expression in diabetes patients appears to be an important genetic determinant in the progression of T2DM. Moreover, age ≥ 50 years and BMI ≥ 25 could be considered risk factors for developing T2DM in the studied population.

RESUMO

Vitamin D receptor (VDR) mediates cellular processes like cell cycle arrest and apoptosis which effect cancer susceptibility. VDR single nucleotide polymorphisms (SNPs) have a significant influence on functioning of VDR protein and subsequently contribute to the risk of cancer occurrence and progression. The present case-control study was carried out between 2016 and 2020 to investigate the association of VDR BsmI/ApaITaqI SNPs with Gastric Cancer (GC) risk in ethnic Kashmiri population not only for establishing a molecular marker for GC but also to facilitate the outcomes of personalized medicine in future. The polymorphisms of BsmI and ApaI of the VDR gene were evaluated using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism followed by Di-Deoxy Sanger sequencing in 143 GC cases and 150 controls. The mean age (in years) was 53.5 ± 7.92 and 51.2 ± 8.25 and mean Body mass index was 22.68 ± 4.27 kg/m2 and 23.81 ± 3.71 kg/m2 for cases and controls respectively. The mean CEA levels of GC cases was 40.2 ± 10.9 ng/ml. Genotypic distribution of VDR BsmI differed significantly between GC cases and controls (GG vs GA + AA; adjusted P = 0.014) and followed dominant mode of inheritence. Stratification of VDR BsmI revealed that frequency of variant genotype (GA + AA) was significantly higher in Preobese GC cases (P = 0.001), GC patients consuming < 5 cups of salt tea/day (P < 0.0001) and with no family history of gastrointestinal cancer (P = 0.014) compared to healthy controls. ATC haplotype associated with high GC risk. In conclusion, our study suggests that VDR BsmI SNP has a significant association with increased risk of GC especially in preobese population and BsmI/ApaITaqI SNPs significantly decreased the overall survival in GC patients of Kashmiri population.

RESUMO

Human polycystic ovary syndrome (PCOS)-a cluster of diseases displays various symptoms associated with endocrine and gynecological disorders in childbearing women. Oral contraceptive pills (OCP) being a drug of choice minimizes symptoms and complications associated with the disorder. But, the controversial data available in literature regarding use of OCPs compels us to setup a study design regarding effect of OCP treatment in PCOS subjects and the possible outcomes specifically regarding coagulation pathways. Two PCOS study groups have been selected according to Rotterdam Criteria: one with OCP treatment (n = 50) and other without any drug treatment i.e., drug naive (n = 50). Anthropometry, Biochemistry, Hormones, Insulin and various clotting factors like Factor XI, Factor V, tPA, TAT-III and D-dimer were analyzed in both groups. The results showed worsening of IR, Metabolic parameters and coagulopathy in OCP group comparative to drug naive group indicating adverse effects of the OCP treatment which puts these women at risk for number of future clinical implications especially Cardiovascular and metabolic complications.

RESUMO

Background: Type II Diabetes mellitus (T2DM) is a multifactorial disease and a leading cause of premature deaths. Inflammatory cytokines are reported that they have potential to enhance insulin resistance and hence T2DM. Assessment of immunological profile in T2DM patients of Kashmir valley is unclear. So, detection of cytokines is relevant to determine the extent and direction of immune responses. The current research was taken to study the role of inflammatory mediators in T2DM along with insulin sensitivity, biochemical and hematological parameters in mountainous valley of Kashmiri population. Methods: A total of 340 subjects were selected in this study among them 160 were T2DM cases and 180 were healthy controls. Serum expression of inflammatory mediators (TNF-α and IL-6 ) were quantified by ELISA technique, WBC count was measured on Sysmax (Germany) hematology analyzer, biochemical and Immunoassay parameters were done on Abbott c4000 (USA) and Abbott C1000 (USA) fully automatic analyzer. Data was analyzed using statistical 'software SPSS 16.1' (Chicago, IL). For all assessments, p<0.05 were considered statistically significant. Results: The expressions of candidate cytokines (TNF-α, IL-6, CRP, and WBC) were highly significant (p<0.001) in T2DM. Among inflammatory mediators, TNF-α shows a positive correlation (p<0.001) with glycemic profile and insulin sensitivity in T2DM cases in comparison with healthy normal. Biochemical (fasting sugar, HbA1c, insulin resistance, lipid profile) and anthropometric (BMI) parameters were highly significant (p<0.001) in T2DM cases as compared to non-diabetic normal. Conclusion: Low grade inflammation and up regulation of inflammatory mediators has been purported to play a significant role in pathogenesis of T2DM. Our findings confirm that positive correlation of TNF-α and IL-6 with T2DM and insulin sensitivity. These can act as early prediction biomarkers of T2DM. Further studies on wider range of pro and anti- inflammatory cytokines i.e. mediators, in association with other biochemical, immunoassay and hematological parameters are needed to help clinicians manage and treat T2DM effectively.

RESUMO

Molecular studies have implicated mutant B-type Raf kinase (BRAFMut) of MAP-kinase signalling pathway in the pathogenesis of several cancers including colorectal cancer. Recently, the prognostic and therapeutic relevance of the most frequent BRAFV600E mutation also has been highlighted in colorectal carcinomas (CRC). Thus, the aim of this study was to investigate the prevalence of BRAFV600E mutation and to determine the correlation between this mutation and indicators of poor prognosis and outcome in patients with CRCs from Kashmir, North India. Here, we developed a highly sensitive technique, mutation allele-specific multiplex PCR (MASMP), for detection of BRAFV600E/BRAFc.1799T>A mutation, the results of which were confirmed by sequencing the product and compared to direct DNA sequencing. In total, BRAFV600E mutation status was analyzed in 57 colorectal tumour samples and an equal number of adjacent normal tissues. A high frequency of BRAFV600E mutation 21% (12/57) was identified in tumour tissues by MASMP compared to only 5.2% by direct DNA sequencing. Statistical analysis indicated that compared to BRAF-negative colorectal tumours, patients with BRAFV600E colorectal tumours were more likely to be >50 years old (61%) (P < 0.03). These tumours were more likely to be of clinical tumour stages III and IV (63%) (P < 0.04) with lymph node metastasis (52%) (P < 0.02) and characterised by a high-grade histology (63%) (P < 0.04). Colorectal patients harbouring BRAFV600E mutation experience more relapse/recurrence (52%) (P < 0.02). We, therefore, conclude that BRAFV600E mutation can be used as an indicator of poor prognosis to predict the outcome for CRC patients from Kashmir. MASMP proved to be a simple, sensitive and reliable technique for screening patients for BRAFV600E mutation. Testing for this mutation may be useful for selecting initial therapy mode and for follow-up monitoring in CRC patients.

RESUMO

Epigenetic alterations, in addition to multiple gene abnormalities, are involved in the genesis and progression of human cancers. Gastrointestinal tract (GIT) cancer is a major medical and economic burden worldwide. Aberrant methylation of CpG islands within promoter regions is associated with transcriptional inactivation of various tumor suppressor genes. Although a number of cancer-associated genes have been found to be hypermethylated in GIT cancer, valuable methylation markers for early diagnosis and prognostic evaluation of this cancer remain largely unknown. O6-methyguanine DNA methyltransferase (MGMT) is a DNA-repair gene that removes mutagenic and cytotoxic adducts from the O6 position of guanine induced by alkylating agents. MGMT promoter hypermethylation and reduced expression have been found in some primary human carcinomas. We studied DNA methylation of CpG islands of the MGMT gene and its relation with MGMT protein expression in human GIT carcinomas. A total of 210 GIT tumor samples and 90 adjacent normal tissues were analyzed for MGMT promoter methylation by methylation-specific polymerase chain reaction after bisulfite modification of DNA and same samples were analyzed for MGMT protein expression by Western blotting. The methylation frequencies of MGMT gene promoter were 41.4%, 34.2%, and 44.2% in stomach, esophageal, and colorectal cancer cases while as 16.6, 13.3, and 13.3 in respective controls. MGMT protein was found downregulated in controls of all GIT. The results suggest that methylation at CpG islands of MGMT may be responsible for the downregulation of MGMT protein expression in GIT cancers.

RESUMO

Type 2 diabetes mellitus (T2DM) is a consequence of complex interactions among multiple genetic variants and environmental risk factors. This complex disorder is also characterized by changes in various adipokines. In this study, our objective was to estimate the levels of adiponectin, leptin, and resistin (ALR) in T2DM patients, besides studying the effect of various drugs on their levels. Study participants included 400 diabetic and 300 normal patients from the Department of Endocrinology and Department of Biochemistry, Govt Medical College Srinagar. Subjects were categorized under various groups, i.e., Group 1 (metformin treated) and Group 2 (glimepiride treated), and cases were also categorized as obese with T2DM (Group A), obese without T2DM (Group B), and T2DM only (Group C). The serum ALR levels were estimated by ELISA (Alere), and biochemical parameters were also evaluated before and after treatment. Adiponectin levels were found to be significantly lower in T2DM cases as compared to controls (12 ± 5.5 versus 22.5 ± 7.9 µg/ml), while leptin and resistin levels were found to be significantly higher than controls (14.3 ± 7.4 versus 7.36 ± 3.73 ng/ml) (13.4 ± 1.56 versus 7.236 ± 2.129 pg/ml). Taking the effect of drugs into consideration, the effect on adiponectin and resistin levels was found to be highly significant in Group 2 before and after treatment (11 ± 5 versus 19.2 ± 4.5 µg/ml) (13.6 ± 2.5 versus 7.3 ± 2.9 pg/ml), while more effect was observed in leptin among Group 1 (metformin)-treated cases (27 ± 15 ng/ml versus 15 ± 15 ng/ml). Further the adiponectin levels were found to be significantly lower in Group B, while leptin and resistin levels were found to be significantly higher among obese cases when compared to T2DM cases only. Glimepiride also shows more effect on FBG, HbA1c% levels, while metformin shows more effect on Lipid profile levels. From the study, it can be concluded that ALR levels are affected by use of antidiabetic drugs among which glimepiride shows more effect on adiponectin and resistin levels, while leptin gets affected more by metformin. It can also be proposed that ALR levels are not affected by diabetes only, suggesting that their alterations in T2DM may be due to obesity as we observed more ALR changes in obese cases when compared to T2DM cases, and so there might be an important link between adiposity and insulin resistance.

RESUMO

Background: Recurrent miscarriage (RM) represents the spontaneous termination of two or more successive pregnancies. TNFα is a proinflammatory cytokine that is often considered harmful for embryonic development when expressed beyond normal levels. Aim: The study was conducted to assess the association between TNFα-308 polymorphism and RM pathogenesis. Methods: Samples of blood were obtained from patients and controls through venipuncture. The levels of TNFα in serum were measured by ELISA. TNFα gene promoter-associated single-nucleotide polymorphism was investigated with polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniques with precise primers and the restriction endonuclease, NcoI. Results: Serum TNFα levels in patients were considerably high (p < 0.05) than controls. The genotype and allele frequencies for TNFα gene polymorphism differs significantly (p = 0.0089; p = 0.0043 respectively) between patients and controls. The TNFα-308 SNP exhibited a link with higher RM risk in heterozygous (GG vs. GA; OR: 3.086, 95% CI: 1.475-6.480; p: 0.0027), dominant (GG vs. GA + AA; OR: 2.919, 95% CI: 1.410-6.056, p: 0.0038), and allelic/codominant (G vs. A; OR: 2.449, 95% CI: 1.313-4.644, p: 0.0064) models. However, this SNP showed an insignificant association with higher and lower RM risk in homozygous (GG vs. AA; OR: 1.915, 95% CI: 0.3804-10.99, p: 0.6560) and recessive (AA vs. GA + GG; OR: 0.6596, 95% CI: 0.1152-3.297, p: >0.9999) models, respectively. Further, the TNFα-308G/A genotype frequencies were in concord with HWE both in the controls (χ2 = 3.235; p = 0.1985) and the patients (χ2 = 0.0117; p = 0.9942). Conclusion: The serum TNFα levels were significantly higher in the patients than the controls. The genotyping analysis also demonstrated that TNFα-308G/A SNP significantly increases the overall risk of RM, suggesting that the SNP modulates the TNFα gene expression and thereby increases serum TNFα levels that adversely affect the pregnancy outcome.

RESUMO

Background: Vitamin D receptor (VDR) gene alterations have been associated with the occurrence and prognosis of various types of cancers, but only few studies have focussed on gastric cancer (GC) risk. Objectives: This case-control study was conceived to evaluate possible association of VDR polymorphisms (Fok1, Taq1, and Cdx2) with GC risk. Materials and Methods: A total of 293 subjects, including 143 GC patients and 150 controls were included in this study. The genotypes were elucidated by polymerase chain reaction-restriction fragment length polymorphism followed by DNA sequencing. Results: The frequency of Fok1 genotypes (TC and TT) was found higher in GC cases compared to controls (P ≤ 0.05). In the stratified analysis, we observed a significant association of the (CT + TT) variant with GC risk in males, rural dwellers, smokers, and preobese cases, and those having no family history of Gastrointestinal cancer (P ≤ 0.05). In silico analysis predicted that the Fok1 variant impacts the stability and functional efficiency of the protein. Some exact haplotypes (CCG and CCA) of the VDR gene may act as low penetrance alleles in inclination to GC. Conclusion: VDR Fok1 polymorphism is significantly associated with GC risk in the Kashmiri population. Specific haplotypes in the VDR gene could act synergistically in the development of GC.

RESUMO

Purpose: Due to a lack of effective antiviral treatment, several vaccines have been put forth to curb SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) infection and to reduce the mortality and morbidity rate by eliciting a protective immune response, primarily through virus-neutralizing antibodies specific for SARS-CoV-2 spike protein. This longitudinal study was designed to evaluate the vaccine effectiveness and immune response following the administration of adenoviral vaccine, COVISHIELD, in Indian population who were previously uninfected with SARS-CoV-2 and to reveal the effect of various sociodemographic, inflammatory and biochemical factors on antibody response. Methods: Briefly, the total immunoglobulin G (IgG) against SARS-CoV-2 spike and nucleocapsid protein along with the immunological markers were estimated by chemiluminescent microparticle immunoassay (CMIA) technology. Biochemical parameters were estimated by spectrometry. Results: A total of 348 subjects received two doses of COVISHIELD (224 males, 124 females). The mean age of the study subjects was 42.03 ± 13.54 years. Although both the doses of COVISHIELD against SARS-CoV-2 spike protein induced a robust immune response that lasted for months in all the subjects, the total IgG titer against SARS-CoV-2 spike protein was found significantly higher in subjects ≥50 years of age, and those with obesity, elevated triglycerides and elevated lactate dehydrogenase levels. Conclusions: There is a definite effect of age and biochemical factors on the immunogenicity of COVISHIELD. An understanding of these factors could not only impact the design of vaccines and help improve vaccine immunogenicity and efficacy but also assist in decisions on vaccination schedules, in order to combat this deadly pandemic.

RESUMO

Transforming growth factor-ß (TGFß) is a pleiotropic secretory cytokine exhibiting both cancer-inhibitory and promoting properties. It transmits its signals via Suppressor of Mother against Decapentaplegic (SMAD) and non-SMAD pathways and regulates cell proliferation, differentiation, invasion, migration, and apoptosis. In non-cancer and early-stage cancer cells, TGFß signaling suppresses cancer progression via inducing apoptosis, cell cycle arrest, or anti-proliferation, and promoting cell differentiation. On the other hand, TGFß may also act as an oncogene in advanced stages of tumors, wherein it develops immune-suppressive tumor microenvironments and induces the proliferation of cancer cells, invasion, angiogenesis, tumorigenesis, and metastasis. Higher TGFß expression leads to the instigation and development of cancer. Therefore, suppressing TGFß signals may present a potential treatment option for inhibiting tumorigenesis and metastasis. Different inhibitory molecules, including ligand traps, anti-sense oligo-nucleotides, small molecule receptor-kinase inhibitors, small molecule inhibitors, and vaccines, have been developed and clinically trialed for blocking the TGFß signaling pathway. These molecules are not pro-oncogenic response-specific but block all signaling effects induced by TGFß. Nonetheless, targeting the activation of TGFß signaling with maximized specificity and minimized toxicity can enhance the efficacy of therapeutic approaches against this signaling pathway. The molecules that are used to target TGFß are non-cytotoxic to cancer cells but designed to curtail the over-activation of invasion and metastasis driving TGFß signaling in stromal and cancer cells. Here, we discussed the critical role of TGFß in tumorigenesis, and metastasis, as well as the outcome and the promising achievement of TGFß inhibitory molecules in the treatment of cancer.

RESUMO

BACKGROUNDS: Thyroid hormones play an important physiological role in human metabolism. Erythrocyte abnormalities are frequently associated with thyroid disorder. However, they are rarely investigated and related to the subclinical and primary hypothyroidism in Kashmiri Patients. In this study an attempt was made to study hematological parameters in untreated and treated subclinical hypothyroidism and primary hypothyroidism patients. METHODS: This retrospective study included 600 subjects, among which were untreated subclinical hypothyroid (n=110), treated subclinical hypothyroid (n=110), untreated primary hypothyroid (n=100), treated primary hypothyroid (n=100) and euthyroid (n=180). This study was carried out at Department of Biochemistry, Government Medical College Srinagar. The hematological parameters and thyroid profile of the subjects were assessed by the Sysmex (Italy) and ECLIA (Germany) 2010 automatic analyzer. Mean, standard deviation (SD), analysis of variance (Two-way ANOVA), and multiple comparisons were used to report our results, with p<0.05 or p<0.01 considered as statistically significant. RESULTS: In this study group we compared the hematological parameters in these groups, untreated subclinical hypothyroid, treated subclinical hypothyroid, untreated primary hypothyroid, treated primary hypothyroid and euthyroid. We found that hematological parameters like Hb, RBC, MCV, HCT, RDW,RBC% were significantly increased in untreated subclinical hypothyroidism and untreated primary hypothyroidsm, with the p value being less than 0.05 whereas, in treated SCH & Pr. Hypothyroid, results were insignificant. The results reported in these groups as mean±SD, were statistically tested by ANOVA and multiple comparison tests. In untreated subclinical hypothyroid the values were: Hb (10.83±1.33 g/dl), RBC (4.21±0.66 10(6)/µl), MCV (84.56±6.84 fL), HCT (38.5±2.2%), RDW (17.91±2.37 fL), RBC% (84.36±13.2%) and in untreated primary hypothyroid, Hb (10.73±0.86 g/dl), RBC (4.63±0.51 10(6)/µl), MCV (83.34±6.92 fL), HCT (38.6±2.6%), RDW (14.93±5.47 fL), RBC% (92.63±10.30%) suggesting that these patients were at risk of anemia and other erythrocyte abnormalities. MCV is an inexpensive approach to study the types of anemia and explore related information like production, destruction, loss and morphological changes of RBC'S. CONCLUSION: The thyroid dysfunction is frequently associated with anemia in subclinical hypothyroidism and primary hypothyroidism. Subclinical hypothyroidism (SCH) is associated with serious complications. Substantial numbers of patients with the risk of SCH could be getting converted into primary hypothyroidism. Such conditions should be identified and corrected. On the other hand, their presence could move to a thyroid dysfunction, allowing its early management.

RESUMO

BACKGROUND: Salt sensitivity is actually a measure of an individual's blood pressure response to salt intake. It has been reported that people who are salt sensitive have high prevalence of hypertension and target organ damage. The link between dietary salt intake and hypertension is well established, and a reduction in salt intake has been shown to lower blood pressure. SCOPE: In Kashmir, this achieves significance because of a high incidence of hypertension along with a high salt intake among ethnic Kashmiris. DESIGN AND METHODS: We analysed clinical variables accompanying salt sensitive hypertension among Kashmiri population in our on-going salt sensitivity study on 770 Kashmiri patients (250 men, 520 women) of age group 18years and above from March 2020 to June 2021. We studied the clinical variables accompanying salt sensitivity and the difference in their blood pressure on. a low salt diet (mean = 2 g/day) vs. their usual salt intake (mean = 11 g/day). To document compliance of salt-restricted diet, we used 24-h urinary NaCl estimation as a surrogate marker for salt intake estimation. RESULTS: We observed, a huge drop in SBP (-28.9 mmHg), DBP (-17.6 mmHg) and mean arterial pressure (-21.3mmHg) in this cohort of 770 ethnic Kashmiris on a strict salt restricted diet. And that women, urban inhabitants, and nonsmokers are more prone to the risk of developing salt sensitive hypertension. Physical activity had no effect on salt sensitivity. CONCLUSION: As per our study, salt restriction has a major role in treatment of Hypertension in Kashmiri Population. More studies need to be focused on this vital area.

RESUMO

Purpose: There has been growing evidence that inflammatory markers play a role in the development as well as severity of Type 2 diabetes mellitus (T2DM). This study has been designed to decipher the involvement of C-Reactive Protein (CRP), Tumor Necrosis Factor (TNFα), Interleukin-6 (IL-6) and Interleukin-10 (IL-10) in the etiopathogenesis of T2DM. Basic procedures: A total of 480 T2DM cases and 540 healthy controls were recruited for the study. Blood samples were collected from each study subject to measure the serum levels of CRP, TNFα, IL-6 and IL-10. Main findings: We found that serum levels of CRP in mg/dl (4.2 ± 0.9), TNFα in pg/ml (34.5 ± 8.8), IL-6 in pg/ml (19.2 ± 7.2) in T2DM patients were significantly high as compared to control participants (CRP; 1.4 ± 0.6, TNFα; 12.7 ± 3.4, IL-6; 3.1 ± 1.4; P < 0.0001). The serum levels of IL-10 in pg/ml were lower in T2DM cases compared to controls (4.35 ± 1.2 vs. 9.6 ± 1.2). In addition, we observed a significant association of CRP levels with insulin resistance, obesity and dyslipidemia. Increased TNFα levels were strongly associated with female gender, Poor glycemic control and strong family history of diabetes. Poor glycemic control was significantly associated with elevated IL-6 levels. Moreover, significantly reduced IL-10 levels were found in T2DM patients with sedentary lifestyle; low educational and rural background. Conclusions: This study showed a strong relationship between TNFα, IL-6, CRP, IL-10 and T2DM patients of Kashmiri ethnicity, treated at SMHS Hospital. Thus, supporting other studies and showing that cytokines may be good markers for T2DM development.

RESUMO

Interleukin-17A (IL17A) is a proinflammatory cytokine and is assumed to play an important role in fetal rejection. In order to evaluate the potential role of IL17A polymorphism in the pathogenesis of recurrent miscarriage (RM), serum IL17A levels were estimated by ELISA. Single-nucleotide polymorphism was assessed by polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) using gene-specific primers and the EcoNI restriction enzyme. Serum IL17A levels were nonsignificantly (p > 0.5) low in RM patients compared with the control group. IL17A gene amplification by PCR yielded the undigested product of 815 bp, and its digestion with EcoNI enzyme produced 815, 529, 286, and 270 bp fragments for the GG genotype; 529, 286, and 270 bp fragments for the GA genotype; and 529 and 286 bp fragments for the AA genotype. The genotype frequency between the RM and control groups exhibited a significant difference (p = 0.001), whereas no significant difference was observed between allele frequencies in the two groups (p = 0.0954). These data suggest that the IL17A gene polymorphism exhibits no significant effect on IL17A gene expression. However, it significantly decreases and increases RM risk in the homozygous and recessive models, suggesting its potential pregnancy-protecting and -harming roles in the AA and GA + GG genotypes, respectively.

RESUMO

Lung cancer is the dominant emerging factor in cancer-related mortality around the globe. Therapeutic interventions for lung cancer are not up to par, mainly due to reoccurrence/relapse, chemoresistance, and late diagnosis. People are currently interested in miRNAs, which are small double-stranded (20-24 ribonucleotides) structures that regulate molecular targets (tumor suppressors, oncogenes) involved in tumorigeneses such as cell proliferation, apoptosis, metastasis, and angiogenesis via post-transcriptional regulation of mRNA. Many studies suggest the emerging role of miRNAs in lung cancer diagnostics, prognostics, and therapeutics. Therefore, it is necessary to intensely explore the miRNOME expression of lung tumors and the development of anti-cancer strategies. The current review focuses on the therapeutic, diagnostic, and prognostic potential of numerous miRNAs in lung cancer.
