Efficacy of Pistacia lentiscus Plant (Rumi Mastagi) in Comparison to Levosulpiride in Patients with Diabetic Gastroparesis: A Double-Blind Non-Inferior Randomised Control Trial Study.

Introduction: Gastrointestinal neuropathies are frequently found in diabetic patients. The pathogenesis of diabetic gastroparesis (DG) is multifactorial. The usual treatment for DG includes dietary modifications, prokinetic and antiemetic agents. There is increasing demand for more effective medicines to treat DG. The current study was conducted on the Pistacia lentiscus stem extract to add to the armamentarium of DG treatment and to find the efficacy of P. lentiscus plant extract (mastic gum) in comparison to levosulpiride in DG for improvement in gastroparesis symptoms and gastric emptying scintigraphy (GES) in a single centric double-blind non-inferiority randomised control trial. Methods: Thirty-eight individuals were recruited and equally randomised into two study groups based on Gastroparesis Cardinal Symptom Index (GCSI) score and TC99 Radionuclide GES, mastic gum group and levosulpiride group. Both pre and post-intervention (8 weeks) GCSI scores were calculated, GES was performed to quantify the improvement in gastric emptying. Power analysis was performed using G*POWER software version 3.1.9.7 and data analysis using SPSS 23.0, variables measured in mean ± standard deviation (SD). Various statistical tests were used such as independent t-test, Chi-square test or Fisher's exact test, Wilcox Mann-Whitney test, analysis of variance (ANOVA) test, and posthoc pairwise tests. Results: The mastic gum is found effective in the improvement of 4 h gastric emptying percentage from the mean (SD) 76.60 (± 9.96) to mean (SD) 97.20 (2.17)% (P < 0.001). Mastic gum has the property of HbA1c reduction, which is more significant than that of levosulpiride (P = 0.044). Mastic gum also had significant Low density lipoprotein (LDL) (mg/dL) levels reduction, (P < 0.001), compared to levosupiride. An absolute increase was observed in haemoglobin (HB) level in mastic gum at a 2-month mean (SD) of 1.03 (0.77) (g/dL) (P-value <0.001). Conclusions: To our knowledge, this is the first study to compare the effect of levosulpiride with mastic gum concerning improvement in diabetic gastroparesis (DG) using GES. In the study, mastic gum was found to have great properties to improve DG with many important pleiotropic effects.

Efficacy of jackfruit components in prevention and control of human disease: A scoping review.

The jackfruit (Artocarpus heterophyllus) is one of the natural remedies significantly used in folk medicine. The ethnopharmacological applications of jackfruit are mainly concerned with the management of inflammation, diarrhea, and diabetes mellitus. Flavonoids, stilbenoids, aryl benzofurans, and lectin jacalin are abundant in jackfruit species. Jacalin is a good indicator for evaluating the immunological state of HIV-1 patients. The extracts and metabolites of jackfruit, particularly those from the leaves, bark, stem, and fruit, contain several beneficial bioactive mixtures. New studies are focused on exploring these bioactive compounds used in various biological activities such as antiviral, antiplatelet, anticancer, antiatherosclerotic, immunomodulatory effects, inhibitors of 5-alpha reductase activity, and the formulation of fast-dissolving tablets (orodispersible, rapid melts porous). Multidisciplinary programs that integrate traditional and modern technology play a crucial role in the lies ahead expansion of jackfruit as the prospective inception of therapeutic compounds. This review aims to highlight significant results on the identification, production, and bioactivity of metabolites found in jackfruit, with current developments in jackfruit research in the control and prevention of human diseases.

Metabolic evaluation of first-time uncomplicated renal stone formers: A prospective study.

Background: Nephrolithiasis is a global health problem. The recurrence rate after the first stone clearance is approximately 50% at 5 years. Metabolic abnormalities are an important factor responsible for stone recurrence. Our prevalidated study aimed to evaluate metabolic abnormalities associated with first-time uncomplicated renal stone formers (FTURSF). Materials and methods: In this prospective, exploratory, time-bound, descriptive study, 30 first-time renal stone formers were evaluated for metabolic abnormalities. High-risk stone formers were excluded from the study. Data were collected in a predefined proforma, transferred to an Excel sheet, and analyzed using the Statistical Package for Social Sciences 20 and Epi Info 7. Fisher exact test, Mann-Whitney U test, paired t test, and Pearson correlation coefficient were used for statistical analyses. Results: The mean age of the participants was 35.57 ± 11.07 years, with a male-to-female ratio of 1.72. The most common abnormality was a 24-hour urine volume of <2.5 L in 73.33% of the participants. One or more metabolic abnormalities were detected in 76.67% of the participants. Other common metabolic abnormalities detected were hypocitraturia (60%), hypercalciuria (16.67%), hyperoxaluria (13.33%), and hyperuricosuria (3.33%). Parathyroid adenoma was detected in one participant (3.33%). Conclusions: Our study documented significant metabolic abnormalities in FTURSF. Therefore, a simplified metabolic evaluation protocol should be adopted while evaluating FTURSF. Detection of an underlying metabolic abnormality would enable the early institution of preventive measures to reduce stone recurrence and related complications.

Genetic Variations in IL-1ß, TNF-α, and TGF-ß Associated with the Severity of Chronic Cervical Spondylitis in Patients.

Chronic cervical spondylitis (CCS), a degenerative disorder of the spine, is known for causing disability among old and young people. Single-nucleotide polymorphisms (SNPs) in various cytokine genes have demonstrated an impactful association with several inflammatory disorders. In the present study, we have investigated the SNPs and allelic distribution of the three most prevalent cytokines genes, IL-1ß (-511C/T), TNF-α (-308G/A), and TGF-ß (-509C/T), along with serum levels of these cytokines in 252 subjects. SNPs were analyzed using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and digested fragments were separated and visualized using agarose gel electrophoresis and Native Polyacrylamide gel electrophoresis (PAGE). The serum cytokine levels were analyzed with a flow cytometer using a customized multiplex bead-based assay. It was observed that these SNPs did not reflect the susceptibility to CCS but were associated with susceptibility to CCS. We found a significant association between the C/C and G/G genotypes and the C and G alleles of IL-1ß and TNF-α, respectively, suggesting a lower risk of CCS. The frequency distribution of risk alleles (-511T) and (-308A) were simultaneously higher in CCS compared to the control, reflecting the susceptibility to CCS. TGF-ß showed a significant association with disease susceptibility, along with a significant correlation between age and the chronicity of CCS. The serum cytokine levels were significantly different in CCS and controls.

Assessment of Vitamin D Levels and Other Bone Related Biochemical Markers in Healthy Adults in Rural Population of Uttarakhand, India.

Despite being close to equator and receiving sufficient sun rays, evidences revealed that Indians have severe deficiency of vitamin D (vit D) ranging from 41 to 100% in different geographical locations. Therefore, in this study levels of 25(OH)D (physiologically measurable form) along with other bone metabolism associated biochemical markers were determined in serum sample of 300 apparently healthy study subjects (rural) from Doiwala block of Dehradun district in the state of Uttarakhand. Demographic data was also obtained based on a structured questionnaire to establish an association between 25(OH)D levels and various dietary and socio-cultural factors. Results demonstrated that of all study subjects, 197 (65%) had 25(OH)D levels below < 12 ng/mL (deficient) and 65 (21%) had 25(OH)D levels between 12 and 20 ng/mL (insufficient) with all other markers falling within respectively established reference ranges. Further, in univariate analysis, gender, occupation (indoor and outdoor), education were independently associated with vitamin D status. Additionally, parathyroid hormone associated significantly with gender and occupation, while calcium associated significantly with gender, occupation and education. Lastly, regression analysis revealed that gender and occupation independently associated with vitamin D status of subjects. In conclusion, apparently healthy subjects showed considerable vitamin D deficiency thereby generating an urgent need for formulating and implementing better government policies for enrichment of vitamin D levels among rural adults of Uttarakhand in future.

Efficacy of Young Cinnamomum zeylanicum Blume Bark on Hyperglycemia and PTPase Activity in Type 2 Diabetes.

Diabetes is a major public health concern and natural easy-going remedies are being searched. Since Cinnamomum zeylanicum Blume has a low coumarin concentration and possible insulin-enhancing properties, it is preferred over all other cinnamon species. Although similar research has been done on humans, there have been very few studies on this particular species, and none among South Asians. Moreover, no human trial that properly described their intervening agent (C. zeylanicum) and checked its efficacy at the molecular level along with clinical variables was conducted. Therefore, the current research aimed to explore the effects of C. zeylanicum on the glycemic index, lipid profile, and expression of the protein tyrosine phosphatase 1 B (PTP1B) enzyme in the peripheral blood mononuclear cells (PBMC) in type 2 diabetes. We examined the presence of bioactive compounds in young C. zeylanicum bark (Alba grade) from native Sri Lanka using gas chromatography-mass spectrometry, high-performance thin-layer chromatography, and thin-layer chromatography before introducing it in the clinical study where trans-Cinnamaldehyde was found to be a major chemical constituent (>60%). Then, from January 2020 to March 2022, a randomized double-blinded placebo-controlled trial was carried out in the Diabetic Clinic at AIIMS Rishikesh. A total of 154 diabetic patients were enrolled and were taken either cinnamon or placebo capsules (1.5 g/day) for 120 days on an empty stomach with warm water along with their conventional treatment. Reduction in fasting blood glucose levels in the cinnamon group was found -35.50% (95% CI, -173 to 58.4), whereas in the placebo group change was 5.00% (95% CI, -165 to 224). For glycosylated hemoglobin, it differed -0.85% (95% CI, -8.2 to 1.6) in the cinnamon group compared to the placebo where it was found 0.15% (95% CI, -6.1 to 5.5). PTP1B expression in PBMC was determined from pre- and post-trial blood samples using the Western Blot, and significant inhibition was also observed (p=0.039). The study result depicts, C. zeylanicum is emerging as a beneficial plant for type 2 diabetes in Northern India and could be used as an adjunctive treatment rather than as a standalone managerial remedy.

Association of serum zinc levels and symptom control of asthma in children and adolescents- a prospective observational study.

Dysregulation of zinc (Zn) homeostasis causes a shift in the Th1/Th2 balance towards a Th2 response, which may lead to a heightened inflammatory response. Asthma is associated with an exaggerated Th2 response to antigens. This study attempts to find the association of serum Zn with the status of symptom control of asthma in children and adolescents with bronchial asthma. A total of 67 asthmatic children, diagnosed as per Global Initiative for Asthma (GINA) 2019 guidelines, were included in the study. Symptom control of asthma was assessed by Asthma Control Test (ACT) and Childhood Asthma Control Test (C-ACT) scores. Spirometry was performed on those participants who were able to perform satisfactorily. Serum Zn was analyzed using the photometric method. Participants were divided into two groups: controlled and uncontrolled groups according to ACT/C-ACT score. Mean age of the participants was 10.78 ± 3.67 years. The mean S. Zn (µg/dL) was 136.97 ± 48.37. This study found a higher mean S. Zn value in the controlled asthma group as compared to the uncontrolled group (158.06 vs 129.23, p = 0.006). At a cutoff of S. Zn (µg/dL) ≥ 126.84, it predicted controlled asthma with a sensitivity of 89% and a specificity of 55%. No significant difference was found between the mean serum Zn levels in terms of age, sex, severity, and CRP levels. CONCLUSION: A significant difference was observed between the mean value of Zn and symptom control of asthma (p = 0.006) with a weak positive correlation between the two which was statistically significant (rho = 0.26, p = 0.031). However, low levels of zinc were not significantly associated with symptom control of asthma. Thus, we conclude that maintaining an adequate zinc level could help in achieving better control of asthma in pediatric populations. WHAT IS KNOWN: • Zinc has a role in immunological response in the pathophysiology of immunological disorders such as bronchial asthma. WHAT IS NEW: • This study adds a significant association of serum zinc levels with symptom control of asthma in pediatric populations. • This study also gives a cut-off value of serum zinc level which predicts adequate symptom control of asthma.

Assessment of Dyslipidemia, Lipid Ratios, and Atherogenic Indices as Cardiovascular Risk Factors in Prediabetic and Diabetic Subjects.

Background Uttarakhand is a small state in northern India that comprises mixed population with people dwelling in both hilly and plain areas. Globally, diabetes mellitus (DM) has already been considered to be a pandemic. Furthermore, cardiovascular diseases (CVD) significantly increase mortality and morbidity in patients suffering from DM. Additionally, dyslipidemia has been identified as an important marker in the development of atherosclerosis and ultimately CVD in patients of prediabetes and diabetes. Thus, the identification of subjects with dyslipidemia in prediabetes might be fruitful in lowering their progression to diabetes and ultimately in decreasing incidences of CVD. Hence, this study was undertaken to assess dyslipidemia via the calculation of atherogenic indices (AI) and lipid ratios in prediabetic and diabetic groups attending tertiary care hospital in Uttarakhand. Materials and Methods This study reviewed retrospective biochemical data of 500 study subjects from e-hospital software of the All India Institute of Medical Sciences, Rishikesh. All study subjects were divided into three groups: 122 controls, 137 prediabetics, and 241 diabetics based on the American Diabetes Association criteria. Study subjects were evaluated for glycated hemoglobin (HbA1c), lipid profile, and AI (total cholesterol [TC]/high-density lipoprotein cholesterol [HDLc], low-density lipoprotein cholesterol [LDLc]/HDLc, TC-HDLc/HDLc, triglycerides [TG]/HDLc). Results Results showed that TC, TG, LDLc, and AI were significantly higher, and HDLc was significantly decreased in prediabetic and diabetic groups compared with controls. Furthermore, HbA1c showed significant positive correlation with lipid profile and AI except atherogenic coefficient (TC-HDL/HDL). Conclusion In conclusion, the current study showed the presence of dyslipidemia in both prediabetic and diabetic groups underlining their importance for screening at the prediabetic stage. Hence, we also recommend screening of the prediabetic group for dyslipidemia to arrest the development of early cardiovascular complications.

Single-Point Insulin Sensitivity Estimator (SPISE) as a Feasible Marker of Insulin Resistance in Adult Metabolic Syndrome: Evaluated in a Hospital Based Cross-Sectional Pilot Study at Tertiary Care Centre of Uttarakhand.

Insulin resistance (IR) plays an important role as a major determinant of Metabolic syndrome (MetS). Various methods are available for measuring insulin resistance but they are laborious, time-consuming, and costly. Therefore various surrogate markers and indices have been devised to simplify and improve the determination of insulin resistance. Recently, a new index, single point insulin sensitivity estimator (SPISE) was proposed in the European population and was found comparable to the gold standard test (hyperinsulinemic euglycemic glucose clamp).This study was planned to evaluate whether SPISE could be a useful potential low-cost indicator for predicting MetS with IR patients in Indian population. Eighty-three participants from outpatient care of AIIMS Rishikesh were evaluated after informed consent. They were divided into Metabolic syndrome (n = 56) and Non Metabolic Syndrome(n = 27), using South Asian Modified National Cholesterol Education Program- ATP-III criteria for metabolic syndrome. SPISE index, HOMA-IR, Insulin Resistance Index, Triglycerides to high-density lipoproteins cholesterol ratio (TG/HDL-C) were calculated for all the subjects. Receiver operating characteristic (ROC) curve was plotted to assess discriminatory ability of SPISE, HOMA-IR, TG/HDL-C ratio, IRI and hs-CRP to differentiate between IR(Metabolic syndrome) and non-IR (Non-Metabolic syndrome) subjects. SPISE has greater area under curve with better sensitivity and specificity compared to HOMA-IR, IRI, TG/HDL-C ratio and hs CRP. So, SPISE has better predictive ability than HOMA-IR, IRI, TG/HDL-C ratio and hs CRP to discriminate IR from non-IR cases. SPISE could be a useful potential low-cost indicator with high sensitivity and specificity for predicting IR in MetS patients.

Detection of differential expression of miRNAs in computerized tomography-guided lung biopsy.

Aims: Nonsmall-cell lung carcinoma comprises 85% of lung malignancies and is usually associated with a poor prognosis due to diagnosis at advanced stages. Molecular diagnosis of computerized tomography (CT)-guided biopsy has the potential to identify subtypes of lung carcinoma like adenocarcinoma (AC) and squamous cell carcinoma (SCC) along with its molecular stratification. This approach will help predict the genetic signature of lung cancer in individual patients. Subjects and Methods: Histopathologically proved a CT-guided biopsy sample of lung cancer cases was used to screen for the expression of microRNA (miRNA) earlier quantitated in blood plasma. Primers against hsa-miR2114, hsa-miR2115, hsa-miR2116, hsa-miR2117, hsa-miR449c, and hsa-miR548q with control RNU6 were used to screen 30 AC, 30 SCC, 5 nonspecific granulomatous inflammation, and 8 control samples. Reverse transcription polymerase chain reaction (RT-PCR) data revealed expression of hsa-miR2114 and hsa-miR548q in AC as well as SCC. Results: RT-PCR data revealed that the expression of hsa-miR2116 and hsa-miR449c was found upregulated in AC while hsa-miR2117 was expressed in SCC cases. Bioinformatic analysis revealed that genes, where these miRNAs are located, were also upregulated while targets of these miRNAs were downregulated. Conclusions: miRNAs expression pattern in the CT-guided biopsy samples can be used as a potential tool to differentially diagnose lung cancer subtypes. The expression pattern of miRNAs matches very well in blood plasma and tissue samples, albeit levels were very low in the earlier case than later. This approach can also be used for screening mutations and other molecular markers in a personalized manner for the management of lung cancer patients.

Severity of Vitamin D Deficiency in Children with Nephrotic Syndrome: A Study from Tertiary Care Center in Northern India.

In nephrotic syndrome (NS) due to podocytopathies, loss of vitamin D binding globulin along with albumin in urine leads to Vitamin D deficient state. We aimed to study the severity of vitamin D deficiency and its clinical correlation in children with NS. We performed a cross-sectional study at a tertiary care hospital in Northern India. Enrolment of children aged 1-18 years was done. Patient's detailed history, numbers of relapse, treatment details, and data regarding various immunomodulatory drugs treatment. Vitamin D level was estimated, and its status was further classified as deficiency <20 ng/mL and insufficiency 20-30 ng/mL as per Global Consensus Recommendations on evaluation, treatment, and prevention of vitamin D deficiency. Continuous variables were compared using tests such as unpaired t-test, Kruskal-Wallis test, and Wilcoxon rank sum test depending on the distribution of parameters. Categorical variables were compared using Chi-squared tests or Fisher's exact test. A total of 96 children with NS were screened, of which 77.1% had vitamin D deficiency. The mean serum vitamin D level was 14.393 ± 8.52 ng/mL. Among the 48 children of the first episode of NS 36 were deficient (36/48 = 75%). Whereas in the relapse category, 30 patients had infrequently relapsing NS (deficient 24/30 = 80%). Eleven children had frequently relapsing NS; among them, 10 were vitamin D deficient (10/11 = 90.9%), and there was a negative correlation between vitamin D level and duration of illness. Vitamin D deficiency is a common comorbidity in children with NS. Given the putative immunomodulatory property of vitamin D, this deficiency should be identified and treated routinely in all cases of NS.

Serum ferritin as a predictive biomarker in COVID-19. A systematic review, meta-analysis and meta-regression analysis.

Ferritin is a known inflammatory biomarker in COVID-19. However, many factors and co-morbidities can confound the level of serum ferritin. This current metaanalysis evaluates serum ferritin level in different severity levels in COVID-19. Studies evaluating serum ferritin level in different clinical contexts (COVID-19 vs. control, mild to moderate vs. severe to critical, non-survivor vs. survivor, organ involvement, ICU and mechanical ventilation requirement) were included (total 9 literature databases searched). Metaanalysis and metaregression was carried out using metaphor "R" package. Compared to control (COVID-19 negative), higher ferritin levels were found among the COVID-19 patients [SMD -0.889 (95% C.I. -1.201, -0.577), I2 = 85%]. Severe to critical COVID-19 patients showed higher ferritin levels compared to mild to moderate COVID-19 patients [SMD 0.882 (0.738, 1.026), I2 = 85%]. In meta-regression, high heterogeneity was observed could be attributed to difference in "mean age", and "percentage of population with concomitant co-morbidities". Non-survivors had higher serum ferritin level compared to survivors [SMD 0.992 (0.672, 1.172), I2 = 92.33%]. In meta-regression, high heterogeneity observed could be attributed to difference in "mean age" and "percentage of male sex". Patients requiring ICU [SMD 0.674 (0.515 to 0.833), I2 = 80%] and mechanical ventilation [SMD 0.430 (0.258, 0.602), I2 = 32%] had higher serum ferritin levels compared to those who didn't. To conclude, serum ferritin level may serve as an important biomarker which can aid in COVID-19 management. However, presence of other co-morbid conditions/confounders warrants cautious interpretation.

Maternal Chromium Levels in Gestational Diabetes: Systematic Review and Meta-Analysis.

The topic of maternal Chromium (Cr) levels in Gestational Diabetes Mellitus (GDM) has remained controversial; some studies have found lower levels of Cr in GDM population, whereas others found no significant changes in Cr status in GDM. Therefore, this systematic review and meta-analysis was aimed at qualitatively and quantitatively synthesizing past studies to find the relationship of maternal Cr levels with GDM. The study protocol was registered at International prospective register for systematic reviews (PROSPERO) (ID CRD42021272979). Strict adherence to the Preferred Reporting Items for Systematic review and Meta-analysis checklist, 2009 was followed during the entire study. Random-effect model for calculation of distribution of true effect sizes was used for the meta-analysis with a confidence interval (CI) of 95%. The pooled Standard Mean Difference of control and GDM groups were compared using Z statistics with a P value of <.05 as significant. Six studies were included for the systematic review and four studies entered meta-analysis. The test of overall effect revealed that the pooled Cr values did not differ significantly between controls and GDM group (Z = 1.52, P =0.13). Heterogeneity between the studies was high (I2 = 97%). A subgroup analysis revealed that results varied as per place of study, trimester of pregnancy, and Cr estimation technique. Results from meta regression analysis revealed that sample size of individual studies (Q = 0.003, P =0.67) and year of publication of studies (Q = 0.22, P =.48) had no significant effect on the overall Standard Mean Difference. Factors such as ethnicity, lack of history of infection, and diet history can influence the results of this study.

Efficacy of DPP-4 inhibitors and SGLT2 inhibitors compared to sulphonylureas in adult patients with diabetes with low c-peptide levels with or without anti-GAD65 antibody positivity.

BACKGROUND AND AIMS: Latent Autoimmune Diabetes of Adulthood (LADA) is different from type 2 diabetes. Present treatment protocols do not reflect that. DPP-4 and SGLT2 inhibitors have changed therapy. DPP-4 inhibitor use has shown delayed decline in beta-cell reserve in LADA. We studied patients with low c-peptide to assess relationship between c-peptide and anti-GAD65 antibody levels and compare DPP-4 inhibitors with SGLT2 inhibitors and sulphonylureas. METHODS: The study was an open-label trial conducted in 156 participants with low c-peptide (<0.8 ng/mL), age > 25 years, recently diagnosed diabetes with HBA1c ≥ 6.5%. Participants were enrolled into three arms: Group A received sulphonylureas + metformin, Group B received DPP-4 inhibitors + metformin, and Group C received SGLT-2 inhibitors + metformin. Serum anti-GAD-65 antibodies were assessed using sandwich ELISA. Participants were assessed on enrolment and after three months of dual pharmacotherapy. RESULTS: The three arms were comparable on enrolment. 52% of participants with low c-peptide had high anti-GAD65 antibody titers. Significant differences were observed after three months - DPP-4 inhibitors reduced HbA1c by 1.1 ± 0.3%, compared to SGLT2 inhibitors (0.8 ± 0.13%) and sulphonylureas (0.7 ± 0.3%) CONCLUSION: DPP-4 inhibitors appear to provide better glycemic control than alternate therapeutic options in patients with low serum c-peptide.

Review on COVID-19 Etiopathogenesis, Clinical Presentation and Treatment Available with Emphasis on ACE2.

In December 2019, Wuhan city in the Hubei province of China reported for the first time a cluster of patients infected with a novel coronavirus, since then there has been an outburst of this disease across the globe affecting millions of human inhabitants. Severe acute respiratory syndrome coronavirus type-2 (SARS-CoV-2), is a member of beta coronavirus family which upon exposure caused a highly infectious disease called novel coronavirus disease-2019 (COVID-19). COVID-19, a probably bat originated disease was declared by World Health Organization (WHO) as a global pandemic in March 2020. Since then, despite rigorous global containment and quarantine efforts, the disease has affected nearly 56,261,952 laboratory confirmed human population and caused deaths of over 1,349,506 lives worldwide. Virus passes in majority through respiratory droplets and then enters lung epithelial cells by binding to angiotensin converting enzyme 2 (ACE2) receptor and there it undergoes replication and targeting host cells causing severe pathogenesis. Majority of human population exposed to SARS-CoV-2 having fully functional immune system undergo asymptomatic infection while 5-10% are symptomatic and only 1-2% are critically affected and requires ventilation support. Older people or people with co-morbidities are severely affected by COVID-19. These categories of patients also display cytokine storm due to dysfunctional immune response which brutally destroys the affected organs and may lead to death in some. Real time PCR is still considered as standard method of diagnosis along with other serology, radiological and biochemical investigations. Till date, no specific validated medication is available for the treatment of COVID-19 patients. Thus, this review provides detailed knowledge about the different landscapes of disease incidence, etiopathogenesis, involvement of various organs, diagnostic criteria's and treatment guidelines followed for management of COVID-19 infection since its inception. In conclusion, extensive research to recognize novel pathways and their cross talk to combat this virus in precarious settings is our future positive hope.

Prevalence of hypertension and associated cardiometabolic risk factors in urban Rishikesh, Uttarakhand.

BACKGROUND: Hypertension is one of the leading causes of premature death worldwide and is a major risk factor for cardiovascular disease and all-of them cause mortality. Out of the estimated 1.13 billion people who have hypertension, less than 1 in 5 people have it under control. AIM AND OBJECTIVES: To study the prevalence of hypertension and associated risk factors in the urban population of Rishikesh and the association of hypertension with other determinants. METHODOLOGY: A community based cross-sectional study was conducted in an urban area of Rishikesh. The World Health Organization (WHO) steps instrument and protocol was used for the assessment of risk factors and measurements. i.e. anthropometry and blood pressure. Sample size was calculated to be 478. Data was entered and analyzed using SPSS Version 20.0. Appropriate statistical tests were done. A P value of < 0.05 was considered significant. RESULTS: The prevalence of hypertension in urban Rishikesh is 32.4%. The prevalence in male and female is 34.5% and 31.3% respectively. Among hypertensives 45.8% had hypertriglyceridemia, 32.2% had low high-density lipoproteins (HDL), 52.25% had fasting blood glucose more than 100, and 55.4% were obese individuals. Multivariate logistic regression analysis identified that age, waist circumference, body mass index, triglycerides level, and physical activity were independently associated with hypertension. CONCLUSIONS: As the prevalence of hypertension and cardiometabolic risk factors were higher, necessary health interventions were required to reduce the morbidity/mortality of the disease.

Differential diagnosis of non-small cell lung carcinoma by circulating microRNA.

INTRODUCTION: More than 70% of lung cancer comprises nonsmall-cell lung carcinoma and is associated with poor survival outcome owing to late diagnosis. Identification of lung cancer in early stages when no clinical signs or symptoms are evident, can drastically improve the prognosis. To this end, we aimed to evaluate the changes occurring at tissue level by assessing the expression of six microRNAs (miRNAs) in lung adenocarcinoma (AC) and squamous cell carcinoma (SCC). MATERIALS AND METHODS: Peripheral blood of histopathologically proven cases of lung AC and SCC was collected and processed for the isolation of miRNAs using commercially available kit. Primers against mir-2114, mir-2115, mir-2116, mir-2117, mir-449c, and mir-548q with loading control Caenorhabditis elegans were used. Screening was carried out in thirty cases of both AC and SCC, whereas twenty healthy controls were included. RESULTS: Real-time polymerase chain reaction data revealed that the expression of mir-2114 and mir-449c in AC and mir-2115 in SCC was significantly upregulated. The expression of these miRNAs was also confirmed in lung AC cell line. The differential pattern of expression of these miRNAs can be used for precise diagnosis of lung carcinoma. CONCLUSIONS: We have used a noninvasive technique to identify the subtype of lung cancer based on molecular genetic signatures. The results suggest that through molecular profiling of miRNA, we can screen high-risk cases for cancer interception.

Unveiling molecular associations of polymorphic variants of VDR gene (FokI, BsmI and ApaI) in multiple myeloma patients of Indian population.

Multiple myeloma (MM) is a plasma cell malignancy frequently accompanied with skeletal co-morbidity. Vitamin D (1,25(OH)2D) is an important mediator of skeletal homeostasis that mediates its effect by binding to vitamin D receptor (VDR), a steroid family receptor and modulates various downstream pathways. Multiple polymorphisms have been determined in VDR gene that witnessed significant association with cancer development and progression. Therefore, in this maiden study, we recruited 75 newly diagnosed MM patients and 75 control subjects. 25-hydroxy vitamin D (25(OH)D) levels were measured in all recruited study subjects. Further, PCR-RFLP was performed in DNA samples of recruited study subjects. Results demonstrated significantly decreased 25(OH)D levels in MM patients compared to controls. Additionally, decreased 25(OH)D levels in MM patients inversely associated with disease severity. Further, single nucleotide polymorphism (SNP) analysis of VDR gene showed significantly higher risk of MM disease development in Ff + ff, Aa + aa, and Bb + bb genotypes. Additionally, FokI f, ApaI a and BsmI b alleles were significantly associated with MM occurrence. In conclusion, this study provided initial evidences of association between 25(OH)D insufficiency, VDR gene polymorphism and MM development. Thus, we suggest that a study involving assessment of 25(OH)D levels and VDR gene polymorphism in large patients' cohort might substantiate their role in MM development which would further provide impetus to give 25(OH)D supplementation along with conventional chemotherapeutic agents for myeloma treatment in future.

Identification of suitable reference genes in blood samples of carcinoma lung patients using quantitative real-time polymerase chain reaction.

INTRODUCTION: Lung cancer (LC), among all other cancers, is the leading cause of death worldwide, while the third most common cancer-causing mortality in India. Several techniques of the assay for early detection of cancer that improve survival rates have been employed in tissues and cell lines. Reverse transcriptase quantitative polymerase chain reaction (RTqPCR) is one of the most common techniques employed for gene expression studies for the normalization of a target gene using a reference gene (RG). The present study used the three most common RGs: glyceraldehyde-3-phosphate dehydrogenase (GAPDH), ß-Actin, and 18s ribosomal ribonucleic acid (18s rRNA), which were assessed by qPCR to validate, as of which is a more effective RG in blood samples of LC patients. MATERIALS AND METHODS: A total of thirty participants with LC of non-small cell and small cell type were included along with twenty healthy controls. Ribonucleic acid (RNA) isolated from peripheral blood mononuclear cells was quantified, prepared for complementary deoxyribose nucleic acid synthesis, and analyzed for expression of three RG on RTqPCR. RESULTS: Expression levels as Ct values of studied RG were reported as mean ± standard deviation for GAPDH (26.97 ± 5.107), ß-actin (20.5 ± 2.3), and 18s rRNA (25.10 ± 4.075). GAPDH showed the lowest expression, whereas ß-actin showed the highest expression among the studied RG in subjects of LC. The expression of GAPDH and 18s rRNA were statistically significantly lower than ß-actin (p < 0.0001), whereas expression levels of GAPDH and 18s rRNA were comparable. However, the expression level of only ß-actin in LC patients was comparable with healthy controls with P < 0.1611 at 95% confidence interval. CONCLUSION: It is concluded that ß -actin may be considered the most suitable RG isolated and studied from peripheral blood mononuclear cells using RT qPCR in LC.

Association of Obesity and Metabolic Syndrome among Urban Dwellers of Rishikesh, Uttarakhand.

BACKGROUND: Noncommunicable diseases include heart disease, stroke, cancer, diabetes, and chronic lung diseases and are collectively responsible for almost 70% of all deaths worldwide. Metabolic syndrome (MetS) predisposes to coronary artery disease irrespective of age, gender, or family history of diabetes. AIM AND OBJECTIVES: The aims of this study were as follows: (1) to assess the prevalence and its predictors of obesity among the urban population, (2) to analyze the association of obesity with MetS, and (3) to analyze the correlation of obesity with different components of MetS. MATERIALS AND METHODS: A community-based cross-sectional study was conducted in an urban area of Rishikesh. The World Health Organization STEPS instrument and protocol were used for the assessment of risk factors and measurements. The sample size was calculated to be 478. Data were analyzed using SPSS version 20.0. Appropriate statistical tests for bivariate and multivariate analysis were done. P < 0.05 was considered statistically significant. RESULTS: The prevalence of MetS among obese individuals was significantly higher (57%) according to the National Cholesterol Educational Program Adult Treatment Panel 3 definition (P < 0.001). The prevalence of MetS in male and female obesity was 56.8% and 57.1%, respectively. Body mass index was significantly correlated with systolic blood pressure (BP) (r = 0.238, P = 0.001), diastolic BP (r = 0.281, P = 0.001), Fasting blood glucose (FBG) (r = 0.136, P = 0.003), and triglycerideTriglycerides (TG) (r = 0.12, P = 0.009) and negatively correlated with High Density Lipoproteins (HDL) (r = -0.041, P = 0.37). Whereas, waist-hip ratio was significantly correlated with systolic BP (r = 0.277, P = 0.001), diastolic BP (r = 0.251, P = 0.001), FBG (r = 0.232, P = 0.001), and TG (r = 0.273, P = 0.001) and not with HDL (r = 0.033, P = 0.466). CONCLUSIONS: As the prevalence of MetS is higher among obese individuals, health interventions required to reduce the morbidity/mortality and need to be addressed in adult populations.
