Efficacy of oral sodium chloride in reducing the incidence of hyponatremia in children with epilepsy receiving oxcarbazepine monotherapy: A randomized controlled trial (SCHO Trial).

INTRODUCTION: Hyponatremia is a well-documented adverse effect of oxcarbazepine treatment, but no clinical trial has yet been conducted to explore any intervention for reducing the incidence of hyponatremia. MATERIALS AND METHODS: This open-label trial evaluated the efficacy of add-on daily oral sodium chloride supplementation of 1-2 g/day for 12 weeks in reducing the incidence of hyponatremia in children receiving oxcarbazepine monotherapy aged 1-18 years. Apart from comparing the incidence of symptomatic and severe hyponatremia, serum and urine sodium levels, serum and urine osmolality, changes in behavior and cognition, and the number of participants with recurrence of seizures and requiring additional antiseizure medication (ASM) were also compared. RESULTS: A total of 120 children (60 in each group) were enrolled. The serum sodium level at 12 weeks in the intervention group was higher than that of the control group (136.5 ± 2.6 vs 135.4 ± 2.5 mEq/L, p = 0.01). The number of patients with hyponatremia was significantly lower in the intervention group (4/60vs14/60, p = 0.01). However, the incidence of symptomatic and severe hyponatremia (0/60vs1/60, p = 0.67 for both), changes in social quotient and child behavior checklist total score (0.6 ± 0.8 vs 0.7 ± 0.5, p = 0.41 and 0.9 ± 1.2 vs 1.1 ± 0.9, p = 0.30 respectively), the number of patients with breakthrough seizures (9/60vs10/60, p = 0.89), and the number of patients requiring additional ASMs (8/60vs10/60, p = 0.79) were comparable in both groups. CONCLUSIONS: Daily oral sodium chloride supplementation is safe and efficacious in reducing the incidence of hyponatremia in children with epilepsy receiving oxcarbazepine monotherapy. However, sodium chloride supplementation does not significantly reduce more clinically meaningful outcome measures like symptomatic and severe hyponatremia. Trial registry No. CTRI/2021/12/038388.

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.

Next generation sequencing uncovers multiple miRNAs associated molecular targets in gallbladder cancer patients.

Gallbladder cancer (GBC) is a lethal disease with surgical resection as the only curative treatment. However, many patients are ineligible for surgery, and current adjuvant treatments exhibit limited effectiveness. Next-generation sequencing has improved our understanding of molecular pathways in cancer, sparking interest in microRNA-based gene regulation. The aim of the study is to identify dysregulated miRNAs in GBC and investigate their potential as therapeutic tools for effective and targeted treatment strategies. GBC and control tissue samples were sequenced for miRNA expression using the Illumina HiSeq platform. Biological processes and related pathways were determined using the Panther and Gene Ontology databases. 439 significantly differentially expressed miRNAs were identified; 19 of them were upregulated and 29 were downregulated. Key enriched biological processes included immune cell apoptosis, endoplasmic reticulum (ER) overload response, and negative regulation of the androgen receptor (AR) signaling pathway. Panther analysis revealed the insulin-like growth factor (IGF)-mitogen activated protein kinases (MAPK) cascade, p38 MAPK pathway, p53 pathway, and FAS (a subgroup of the tumor necrosis factor receptor) signaling pathway as highly enriched among dysregulated miRNAs. Kirsten rat sarcoma virus (KRAS), AR, and interferon gamma (IFN-γ) pathways were identified among the key pathways potentially amenable to targeted therapy. We concluded that a combination approach involving miRNA-based interventions could enhance therapeutic outcomes. Our research emphasizes the importance of precision medicine, targeting pathways using sense and anti-sense miRNAs as potential therapies in GBC.

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.

Thalassemia and Hemoglobinopathy Screening in Women Attending Antenatal Clinic at a Tertiary Care Center in Uttarakhand, India: A Re-look at the Laboratory Parameters Mandating High-Performance Liquid Chromatography Workup.

INTRODUCTION: Thalassemia and hemoglobinopathies are the most common inherited hematological disorders. Of these, ß thalassemia is the commonest disorder reported in India, followed by certain hemoglobinopathies encountered in different regions of the country. The data pertaining to the incidence of these disorders in the Uttarakhand region of India are sparse. AIM AND OBJECTIVES: To ascertain the prevalence and spectrum of thalassemia/hemoglobinopathies amongst antenatal women in Uttarakhand. The study also aimed to analyze the ability of red cell indices in differentiating beta thalassemia trait (BTT) from mild iron deficiency anemia (IDA). MATERIAL AND METHODS: A total of 460 pregnant women in the first trimester of pregnancy were screened by cation exchange high-performance liquid chromatography. Retention time and proportions of normal/abnormal hemoglobin peaks were documented in all cases. Hemoglobin A2 (HbA2) values of ≥4% were taken as a cut-off for diagnosing BTT. Blood samples were also collected for complete blood counts, reticulocyte counts, and serum ferritin. The ability of the various discriminatory indices to differentiate between IDA and BTT was also assessed. RESULTS: The prevalence of BTT and hemoglobin D-Punjab trait amongst pregnant women was found to be 2.6% and 0.2%, respectively. RBC count, mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) were found to be moderately strong predictors of BTT, with an area under the curve of 0.860, 0.857, and 0.842, respectively, which were comparable to the discriminatory indices found to be most useful in this study. CONCLUSION: In view of the 2.6% prevalence of BTT in antenatal women in this region of Uttarakhand, a routine screening will be helpful in detecting carriers early in the antenatal period. Careful interpretation of red cell indices is crucial to the distinction between BTT and IDA. Discriminatory indices are reasonably accurate in differentiating BTT from mild iron deficiency, but for practical purposes, MCV and MCH provide equivalent information to identify cases that require further workup.

Association of Serum Leptin With Body Mass Index in Gallbladder Cancer Patients: A Pilot Study.

BACKGROUND: Leptin has been proposed to be a link between obesity and the increased incidence of various cancers like breast cancer, colon cancer, gastric cancer, etc. The role of leptin in gallbladder cancer is largely undetermined. Moreover, no study has evaluated serum leptin levels and their correlation with clinicopathological characteristics and serum tumour markers in gallbladder cancer (GBC). Therefore, the present study was planned. METHODS: A cross-sectional study was conducted in a tertiary care hospital in Northern India after obtaining ethical approval from the institution. Forty GBC patients staged as per American Joint Committee on Cancer (AJCC) 8th staging system were recruited along with 40 healthy controls. Serum leptin was assayed by sandwich enzyme-linked immunosorbent assay (ELISA) and tumour markers (CA19-9, CEA and CA125) by Chemiluminescence. ROC, Mann Whitney U test, Linear regression and Spearman correlation was performed using Statistical Product and Service Solutions (SPSS) (IBM SPSS Statistics for Windows, Version 25.0, Armonk, NY). BMI was also assessed for both groups. RESULTS: Median BMI for GBC patients was 19.46 (IQR 17.61-22.36). Median serum leptin levels were significantly lower (2.09 (IQR 1.01-7.76) ng/mL) in GBC patients as compared to controls (12.32 (IQR 10.50-14.72) ng/mL). AUC was 0.84 with 100% sensitivity and 75% specificity at 7.57 ng/mL. Serum leptin was not associated with cancer stage, resectability, metastasis, liver infiltration, or tumour markers on linear regression (p=0.74, adjusted R square = -0.07). A significant positive correlation was found between BMI and serum leptin in GBC patients (p=0.00). CONCLUSIONS: Lower BMI and relatively lean presentation of GBC patients may account for low serum leptin levels.

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 Visual Evoked Potential to Detect Visual Pathway Dysfunction in Gestational Diabetes Mellitus: A Longitudinal Case-Control Study With Postpartum Follow-up.

BACKGROUND: The increasing prevalence of gestational diabetes mellitus (GDM) during pregnancy has opened the opportunity to study its short- and long-term effects on maternal ophthalmic health. Visual evoked potential (VEP) is a non-invasive electrophysiological test that detects functional disturbances along the visual pathway before the physical signs of diabetic retinopathy (DR) can set in. This longitudinal study is aimed at the assessment of changes in VEP in GDM during different stages of pregnancy and 6-12 weeks after parturition by comparing it with normoglycemic controls. DESIGN AND METHOD: Diagnosed cases of GDM were recruited along with normoglycemic controls at 24-28 weeks of gestation. Each participant was required to attend two follow-up appointments at 32-38 weeks of gestation and 6-12 weeks after parturition. A blood sample was taken in a fasting state to record biochemical parameters. VEP was recorded using Neuropack S1 MEB-9400 electrodiagnostic equipment (Nihon Kohden, Tokyo, Japan) in a dark room by providing pattern reversal stimuli to each eye. RESULTS: A total of 29 participants (15 in the control group and 14 in the GDM group) completed the entire study procedure. The observed mean P100 latency of both eyes in the GDM group was recorded longer as compared to that in the control group at baseline and during late pregnancy. Although the mean P100 latency saw a significant decline in postpartum visits as compared to that in late pregnancy, the values were higher than in the control group. P100 latency at baseline correlated significantly to serum advanced glycated end products' (AGE'S) levels in the GDM group. CONCLUSION: Our study findings reflect that the diagnosis of GDM is associated with significant changes in VEP during and after pregnancy as compared to that of healthy pregnant women.

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.

Utility of IL-6 in the Diagnosis, Treatment and Prognosis of COVID-19 Patients: A Longitudinal Study.

COVID-19 has caused devastating effects worldwide ever since its origin in December 2019. IL-6 is one of the chief markers used in the management of COVID-19. We conducted a longitudinal study to investigate the role of IL-6 in diagnosis, treatment, and prognosis of COVID-19-related cytokine storm. Patients with COVID-19 who were admitted at AIIMS Rishikesh from March to December 2020 were included in the study. Patients with no baseline IL-6 value at admission and for whom clinical data were not available were excluded. Clinical and laboratory data of these patients were collected from the e-hospital portal and entered in an excel sheet. Correlation was seen with other inflammatory markers and outcomes were assessed using MS Excel 2010 and SPSS software. A total of 131 patients were included in the study. Of these, 74.8% were males, with mean age 55.03 ± 13.57 years, and mean duration from symptom onset being 6.69 ± 6.3 days. A total of 82.4% had WHO severe category COVID-19, with 46.56% having severe hypoxia at presentation and 61.8% of them having some comorbidity. Spearman rank correlation coefficient of IL-6 with D-dimer was 0.203, with LDH was -0.005, with ferritin was 0.3, and with uric acid was 0.123. A total of 11 patients received Tocilizumab at a mean duration from symptom onset of 18.09 days, and 100% mortality was observed. Deaths were reported more in the group with IL-6 ≥ 40 pg/mL (57.1% vs. 40.2%, p = 0.06). ICU admissions and ventilator requirement were higher in the IL-6 ≥ 40 pg/mL group (95.9% vs. 91.4%, p = 0.32 and 55.1% vs. 37.8%, p = 0.05). The study showed that IL-6 can be used as a possible "thrombotic cytokine marker". Higher values of IL-6 (≥40 pg/mL) are associated with more deaths, ICU admissions, and ventilator requirement.

An Insight Into the Association of Sclerostin With Insulin Sensitivity and Glycemic Parameters in Male Indian Prediabetic and Diabetic Population.

Background Type 2 diabetes (T2D) is increasing day by day and creating a huge financial and social burden on the Indian population. Insulin resistance results in hyperglycemia, a condition that eventually causes prediabetes and Type 2 diabetes. The etiopathogenesis of T2D is still not clearly defined. Wnt signaling pathway is involved in pancreas development, islet function, insulin production, and secretion. Recent studies show that sclerostin, a Wnt signaling inhibitor, is associated with diabetes. The sclerostin level is altered as a function of race and ethnicity. However, no study has been conducted to observe the sclerostin level in prediabetic and diabetic individuals in the Indian population. Objectives The main objectives of the study are: to determine whether sclerostin is associated with glycemic parameters, serum insulin levels, insulin resistance/ sensitivity, beta-cell function, and adipose tissue insulin resistance (Adipo-IR). Methods This observational study was carried out at a tertiary care hospital, in Rishikesh, Uttarakhand, India. Individuals with T2D and prediabetes and healthy references were included in this study. Sclerostin and free fatty acids (FFA) were measured with the enzyme-linked immunosorbent assay (ELISA), and blood sugar, insulin, and glycated haemoglobin (HbA1c) were measured by the hexokinase, chemiluminescent, and chromatography methods, respectively. Messenger RNA (mRNA) was quantified by real-time polymerase chain reaction (PCR) using the SYBR Green protocol. Adipo-IR, homeostasis model assessment-estimated insulin resistance (HOMA-IR), homeostasis model assessment of ß-cell function (HOMA-B), quantitative insulin sensitivity check index (QUICKI), and single point insulin sensitivity estimator (SPISE) indices were calculated. Results A total of 171 study participants were enrolled in type 2 diabetes, prediabetes, and controls groups, having 57 each in the group. There was a gradual increase in sclerostin levels from healthy [242.12(158.44)] to prediabetes [256.06(299.65)] and diabetes [465.76 (735.71)] with a significant (<0.001) difference from healthy reference. Sclerostin showed a significant positive correlation with fasting blood sugar (r=0.200; p=0.009), HbA1c (r=0.394; p<0.001) and free fatty acids (r=0.205; p=0.007) in total study participants. The SPISE index showed a significant positive correlation (r=0.269, p=0.043) in the prediabetic group. SOST, GLUT4, and insulin receptor (IR) mRNA expression all corroborate with the glycemic status. Conclusion Significantly higher expression of sclerostin (both protein and gene) in newly diagnosed T2D and prediabetes male patients, as well as significant association with SPISE index, suggest that sclerostin might be an indicator of pathophysiology related to insulin resistance, which is a characteristic feature of diabetes mellitus. However, the identification of causal relationships would warrant a large-scale prospective cohort study.

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.

Derivation of a Modified Friedewald's equation for LDL cholesterol estimation in Sub-Himalayan population: A comparative study.

Background: Despite the availability of alternative homogenous assays for LDL-C measurement, most of the laboratories still use Friedewald Equation (FE). However, various novel equations have shown better performance than FE specific to a particular population. Besides, no equation has been devised for use in Sub-Himalayan population. Methods: A cross-sectional laboratory data-based study was conducted by recruiting lipid profiles of 1851 samples to validate 10 different equations for calculating LDL and to devise a novel Modified Friedewald Equation (MFE) specific for Sub-Himalayan population. Results: The novel MFE is presented as: LDL-C = -2.421 + (0.752 × TC) - (0.047 × TG) - (0.350 × HDL). A significant difference was observed between direct LDL-C (118.84 ± 40.39 mg/dL) and all other equations except MFE (118.84 ± 37.96 mg/dl, P > 0.999) and Puavilai Equation (117.99 ± 49.05 mg/dL, P = 0.138). Additionally, MFE showed lowest mean percentage bias of 0.14% with 95% limits of agreement within ± 2SD on Bland-Altman analysis. On ROC analysis at cut-offs of clinical decision limits of 100 mg/dl, 130 mg/dl, 160 mg/dl, and 190 mg/dl, MFE outperformed all other equations with highest AUC (0.974, 0.978, 0.982, and 0.995) respectively with specificity >95% at higher levels. MFE also showed highest correlation (r = 0.954, P < 0.001) and least rMSE (13.8) with direct LDL although all the equations showed significant positive correlation with direct LDL (p < 0.001). Conclusion: MFE derived in this study showed a better diagnostic performance as compared to other 10 equations taking Direct LDL-C as gold standard for Sub-Himalayan Population and may be used as a substitute for FE in the study population.

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.

Efficacy of Pro-Kinetic Agents in Type 2 Diabetes Mellitus Patients With Gastroparesis Using Lactulose Hydrogen Breath Testing: A Randomized Trial.

Aim The aim of the study was to determine the efficacy of prokinetic agents in diabetic gastroparesis patients. Method This was a randomized open-label trial conducted on 50 patients with type 2 diabetes experiencing diabetic gastroparesis, which was diagnosed with the lactulose hydrogen breath test. After randomization, all 50 patients were divided into four arms (cinitapride, metoclopramide, levosulpiride, and domperidone) of different prokinetics and followed up for four weeks; after which, repeat gastroparesis cardinal symptom index score and orocecal transit time were recorded in order to assess the response to the treatment. Result There was no statistically significant difference among the four groups in terms of all the baseline characteristics except for gender (p=0.032). The follow-up gastroparesis cardinal symptom index was collected for 50 patients but repeat orocecal transit time could be performed only in 37 patients. In all four groups, there was a statistically significant (p<0.05) improvement in terms of orocecal transit time and gastroparesis cardinal symptom index scores. But there was no statistically significant difference in relative efficacy amongst these study groups. Conclusion Our study showed statistically significant improvement with four prokinetics drugs in terms of gastroparesis cardinal symptom index score and orocecal transit time, but there was no statistically significant benefit of one prokinetic drug over the other. Our study showed promising results with regard to prokinetic use in diabetic gastroparesis.

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.
