Serum apolipoproteins (apoA-1, apoB, and apoB/apoA-1 ratio) for early identification of dyslipidemia in children with CKD.

BACKGROUND: Dyslipidemia in children with chronic kidney disease (CKD) is identified based on lipid profile parameters; however, changes in lipoprotein quality precede quantitative changes. METHODS: A cross-sectional study was done from January to October 2021; overweight, obese children, known cases of diabetes mellitus, hypothyroidism or on steroid therapy, or lipid lowering drugs were excluded. Clinical details were elicited and examinations done. Besides hemogram, kidney function tests, liver function tests, total cholesterol, low density lipoproteins (LDL), triglycerides, high density lipoproteins (HDL), and apolipoproteins A-1 and B were estimated to identify dyslipidemia. Relevant tests of significance were applied, and ROC curves were drawn for apoA-1, apoB, and apoB/apoA-1 ratios. RESULTS: A total of 76 (61 M:15 F) children with median (IQR) age 7 (3.25-11) years were enrolled; cause of CKD was CAKUT in 82.3% patients. Dyslipidemia (alteration of 1 or more lipid parameters) was seen in 78.9% with a prevalence of 71.7% in early and 95.7% in later stages of CKD (P = 0.02); most had elevated serum triglyceride levels. The median (IQR) values of apoB, apoA-1, and apoB/apoA-1 ratio were 78 (58-110) mg/dl, 80 (63-96.75) mg/dl, and 0.88 (0.68-1.41), respectively; apoB, apoA-1, and apoB/apoA-1 ratio had a sensitivity of 26.67%, 86.67%, and 70%, respectively, and specificity of 87.5%, 62.5%, and 62.5%, respectively, for diagnosis of dyslipidemia. The ROC for apoB, apoA-1, and apoB/apoA-1 ratio showed AUC of 0.66, 0.68, and 0.74 (P = 0.4, 0.02, < 0.01), respectively. CONCLUSIONS: The prevalence (78.9%) of dyslipidemia was high in patients with CKD especially in those with later stages. The ratio of apoB/apoA-1 was altered early and appears to be promising for early detection.

L-ornithine L-aspartate in acute treatment of severe hepatic encephalopathy: A double-blind randomized controlled trial.

BACKGROUND AND AIMS: Data on the use of intravenous L-ornithine L-aspartate (LOLA) in the treatment of overt HE (OHE) is limited. We evaluated the role of intravenous LOLA in patients of cirrhosis with OHE grade III-IV. APPROACH AND RESULTS: In a double-blind randomized placebo-controlled trial, 140 patients were randomized to a combination of LOLA, lactulose, and rifaximin (n = 70) or placebo, lactulose, and rifaximin (n = 70). LOLA was given as continuous intravenous infusion at a dose of 30 g over 24 h for 5 days. Ammonia levels, TNF-α, ILs, and endotoxins were measured on days 0 and 5. The primary outcome was the improvement in the grade of HE at day 5. Higher rates of improvement in grade of HE (92.5% vs. 66%, p < 0.001), lower time to recovery (2.70 ± 0.46 vs. 3.00 ± 0.87 days, p = 0.03), and lower 28-day mortality (16.4% vs. 41.8%, p = 0.001) were seen in the LOLA group as compared with placebo. Levels of inflammatory markers were reduced in both groups. Significantly higher reductions in levels of blood ammonia, IL-6, and TNF-α were seen in the LOLA group. CONCLUSIONS: Combination of LOLA with lactulose and rifaximin was more effective than only lactulose and rifaximin in improving grades of HE, recovery time from encephalopathy, with lower 28-day mortality.

A double blind randomized controlled trial to assess efficacy of nutritional therapy for prevention of recurrence of hepatic encephalopathy in patients with cirrhosis.

BACKGROUND AND AIM: Overt hepatic encephalopathy (OHE) has high risk of recurrence and is associated with poor survival. The role of nutrition therapy is well documented in cirrhosis, but its efficacy in preventing the recurrence of OHE has not been studied. METHODS: In double blind RCT, we randomly assigned 150 patients with liver cirrhosis, with history of OHE in recent past to receive nutrition therapy (group I) or no nutrition therapy (group II) and followed up for 6 months. The primary efficacy end points were occurrence of breakthrough episodes and time to breakthrough episode of OHE. Secondary end points were OHE related hospitalizations and time to hospitalization involving OHE. Other parameters included anthropometry, changes in serum cytokines (IL-1, IL-6, IL-10, and TNF-α), endotoxin and myostatin. RESULTS: There was significant reduction in occurrence of breakthrough episodes of OHE in group I [10 vs 36, hazard ratio 0.20; P < 0.001], OHE-related hospitalization [8 vs 24, hazard ratio 0.27; P < 0.001)]. Times to breakthrough episode of OHE and OHE-related hospitalization were longer in group I. At the end of 6 months, inflammatory and anthropometry parameters showed significant improvement in group I compared with worsening of serum albumin, anthropometric parameters, IL-6, IL-10 and TNF-α in group II. At the end of 6 months, ascites (50 vs 66, P = 0.01), gastrointestinal bleed (2 vs 11, P = 0.007), and jaundice (16 vs 41, P < 0.001) were lower in group I. CONCLUSIONS: Treatment with nutrition therapy prevented recurrence of OHE and decreased OHE-related hospitalizations as compared with no nutrition therapy.

Nutritional therapy for persistent cognitive impairment after resolution of overt hepatic encephalopathy in patients with cirrhosis: A double-blind randomized controlled trial.

BACKGROUND AND AIM: Minimal hepatic encephalopathy (MHE) reflects cognitive impairment in patients with liver cirrhosis and is associated with poor prognosis. We assessed the effects of nutritional therapy on cognitive functions, health-related quality of life (HRQOL), anthropometry, endotoxins, and inflammatory markers in cirrhotic patients with MHE. METHODS: In a double-blind randomized controlled trial, cirrhotic patients with MHE were randomized to nutritional therapy (group I: 30-35 kcal/kg/day and 1.0-1.5 g of protein/kg/day) and no nutritional therapy (group II: diet as patients were taking before) for 6 months. MHE was diagnosed based on psychometric hepatic encephalopathy score (PHES). Anthropometry, ammonia, endotoxins, inflammatory markers, myostatin, and HRQOL were assessed at baseline and after 6 months. Primary endpoints were improvement or worsening in MHE and HRQOL. RESULTS: A total of 150 patients were randomized to group I (n = 75, age 46.3 ± 12.5 years, 58 men) and group II (n = 75, age 45.2 ± 9.3 years, 56 men). Baseline PHES (-8.16 ± 1.42 vs -8.24 ± 1.43; P = 0.54) was comparable in both groups. Reversal of MHE was higher in group I (73.2% vs 21.4%; P = 0.001) than group II. Improvement in PHES (Δ PHES 4.0 ± 0.60 vs -4.18 ± 0.40; P = 0.001), HRQOL (Δ Sickness Impact Profile 3.24 ± 3.63 vs 0.54 ± 3.58; P = 0.001), anthropometry, ammonia, endotoxins, cytokines, and myostatin levels was also significantly higher in group I than group II. Overt hepatic encephalopathy developed in 6 patients in group I and 13 in group II (P = 0.04). CONCLUSIONS: Nutritional therapy is effective in treatment of MHE and associated with improvement in nutritional status, HRQOL, ammonia, endotoxins, inflammatory markers, and myostatin levels.

Ligand decorated biodegradable nanomedicine in the treatment of cancer.

Cancer is one of the major global health problems, responsible for the second-highest number of deaths. The genetic and epigenetic changes in the oncogenes or tumor suppressor genes alter the regulatory pathways leading to its onset and progression. Conventional methods are used in appropriate combinations for the treatment. Surgery effectively treats localized tumors; however, it fails to treat metastatic tumors, leading to a spread in other organs, causing a high recurrence rate and death. Among the different strategies, the nanocarriers-based approach is highly sought for, but its nonspecific delivery can cause a profound side effect on healthy cells. Targeted nanomedicine has the advantage of targeting cancer cells specifically by interacting with the receptors overexpressed on their surface, overcoming its non-specificity to target healthy cells. Nanocarriers prepared from biodegradable and biocompatible materials are decorated with different ligands by encapsulating therapeutic or diagnostic agents or both to target cancer cells overexpressing the receptors. Scientists are now utilizing a theranostic approach to simultaneously evaluate nanocarrier bio-distribution and its effect on the treatment regime. Herein, we have summarized the recent 5-year efforts in the development of the ligands decorated biodegradable nanocarriers, as a targeted nanomedicine approach, which has been highly promising in the treatment of cancer.

Raised CA19-9 and CEA have prognostic relevance in gallbladder carcinoma.

BACKGROUND: Role of tumor markers in gall bladder carcinoma (GBC) is not well established. We evaluated the prognostic value of carbohydrate antigen 19-9 (CA19-9) and carcinoma embryonic antigen (CEA) in patients with GBC. METHODS: Of the 225 patients of GBC enrolled,176 patients were included in the study (excluded 49 patients with jaundice). Patients were divided into 3 groups; resectable n = 92, unresectable n = 17, metastatic n = 67. The clinico-pathological characteristics, tumor markers and survival data were analysed. The cutoff values of CA19-9 & CEA for predicting metastases were computed using receiver operating characteristic curve. Kaplan Meir survival and Cox regression analysis were done for factors predicting survival and recurrence. RESULTS: The median value of Ca19-9 was significantly higher in metastatic group [resectable: 21.3, unresectable: 53.9 and metastatic: 79; p < 0.001] but not for CEA [3.5, 7.8 and 5 ng/ml (p = 0.20)]. A cutoff value of 72 IU/ml for CA19-9, 5 ng/ml for CEA had a sensitivity and specificity of 52 and 80%, 51 and 72% respectively for detection of metastatic disease. Median, 3-year & 5-year survival were significantly lower in patients with CEA > 4 (p = 0.041), Ca19.9 > 37 (p = 0.019), T3/T4 (p = 0.001), node positive (p = 0.001) and presence of perineural invasion (p = 0.001). However, on multivariate analysis, only Ca19.9 > 37 predicted recurrence (p = 0.002, HR 5.8). CONCLUSIONS: Raised CA19.9 and CEA predict metastatic disease in patients with GBC without jaundice with a high specificity and may help in prognostication of the patient. CA19-9 was better than CEA in prediction of tumor burden and in predicting recurrence.

Assessment of Interleukin-18 gene polymorphism and serum levels in oral lichen planus in an Indian population.

BACKGROUND: Oral lichen planus (OLP) is a chronic, inflammatory disease with uncertain etiology. The aim of this study was to assess Interleukin-18 (IL-18) gene polymorphism and serum levels in OLP cases of Indian origin and to compare them with a control population of similar background. METHODS: The assessment of single-nucleotide polymorphisms (SNPs) of IL-18 gene at promoter regions -137(G/C) and -607(C/A) was done in 70 OLP cases and 70 healthy controls using sequence-specific primer-polymerase chain reaction (SSP-PCR). In a subset of this cohort, comprising of 41 OLP cases and 41 controls, serum IL-18 levels were assessed using enzyme-linked immunosorbent assay (ELISA). RESULTS: Mean serum levels of IL-18 among OLP cases were significantly higher when compared to controls. Genotypic and allelic frequencies of IL-18 at position -137(G/C) showed that GG genotype and allele G was significantly higher in OLP cases, whereas, GC genotype and C allele was high in the control group. Polymorphism of IL-18 at position -607(C/A) showed no significant differences. CONCLUSIONS: Gene polymorphism at -137GG genotype and allele G seems to be associated with genetic susceptibility to OLP whereas -137GC and allele C may have a protective role against its development. However, our study lacks clear statistical correlation, the differences observed could be caused by sampling problems and the results could not be fully representative of Indian patients with OLP. Further studies are warranted to explore the role of IL-18 genetic polymorphisms in OLP development.

Correlation of Cyfra 21-1 levels in saliva and serum with CK19 mRNA expression in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) accounts for 90 % of malignant lesions of oral cavity. The study assessed the potential of Cyfra 21-1 as a tumor marker in OSCC. The study included 50 patients of OSCC to evaluate levels of Cyfra 21-1 in serum and saliva by electrochemiluminescent immunoassay (ECLIA) and CK19 messenger RNA (mRNA) expression in tissue by florescent quantitative real-time reverse transcriptase polymerase chain reaction (RT-PCR) along with healthy individuals as control. The salivary and serum Cyfra 21-1 levels in patients of OSCC were significantly higher compared to controls (p value < 0.01). There was a 2.75-fold increase in CK19 mRNA expression in OSCC cases compared to controls. A significant positive correlation was found between serum and salivary Cyfra 21-1, serum Cyfra 21-1, and CK19 mRNA expression and between salivary Cyfra 21-1 and CK19 mRNA expression. Among these, correlation between serum and salivary Cyfra 21-1 was highly significant. Salivary and serum Cyfra 21-1 showed significantly elevated levels in grade II OSCC compared to grade I histopathologically. Elevated levels of salivary Cyfra 21-1 were associated with recurrence in OSCC patients. Reverse operating curve constructed using 3 ng/ml as a cutoff for serum Cyfra 21-1 revealed the sensitivity and specificity to be 88 and 78.2 %, respectively. Using a cutoff value of 8.5 ng/ml for salivary Cyfra 21-1, the sensitivity was found to be 93.8 % and specificity 84.3 %. We advocate salivary Cyfra 21-1 as a better diagnostic marker over serum Cyfra 21-1 as well as a potential marker in the prognosis of OSCC.

Comparison of Urinary Beta-2 Microglobulin Levels in Children with SSNS and Calcineurin Inhibitor-Treated SRNS.

Background: While the utility of beta-2 microglobulin (ß2M) has been explored in various renal conditions to identify tubulointerstitial damage, it has not been adequately studied in nephrotic syndrome. The primary objective of the study was to compare urinary ß2M levels in children with steroid-sensitive nephrotic syndrome (SSNS) and steroid-resistant nephrotic syndrome (SRNS) in disease remission. Materials and Methods: This cross-sectional study was done at a tertiary care hospital between April 2019 and March 2020. Sixty children (2-18 years) with SSNS and SRNS (30 in each group) in remission were enrolled. SRNS patients were included after ≥1 year of treatment with calcineurin inhibitors (CNIs). Biochemical investigations were done to confirm remission; spot samples for urinary ß2M were collected and estimation was done by an enzyme-linked immunosorbent assay (ELISA)-based kit. Results: Of the 60 children, 63% were boys. The median (interquartile range [IQR]) age at enrollment for SSNS and SRNS patients was 7 (4.1-9) and 11 (8.3-12) years, respectively. Urinary ß2M levels were significantly higher in SRNS patients compared to SSNS patients (2.6 vs. 0.75 mg/ml, P < 0.0001). Patients who received cyclosporine for >2 years had higher median urinary ß2M levels compared to those who received it for a shorter period (2.63 vs. 1.83 mg/ml, P = 0.03). Median ß2M levels were higher in focal segmental glomerulosclerosis than minimal change disease (3.5 vs. 2.5 mg/ml). Conclusion: Urinary ß2M levels were higher in SRNS compared to SSNS disease in remission, and ß2M levels correlated well with CNI use of >2 years. It appears to be a promising noninvasive tool to identify early tubular damage and progression in patients with nephrotic syndrome, especially SRNS.

An update on the cell-free DNA-derived methylome as a non-invasive biomarker for coronary artery disease.

Cardiovascular diseases are the foremost contributor to global mortality, presenting a complex etiology and an expanding array of risk factors. Coronary artery disease characterized by atherosclerotic plaque build-up in the coronary arteries, imposes significant mortality and financial burdens, especially in low- and middle-income nations. The pathogenesis of coronary artery disease involves a multifaceted interplay of genetic, environmental, and epigenetic factors. Epigenetic regulation contributes to the dynamic control of gene expression without altering the underlying DNA sequence. The mounting evidence that highlights the pivotal role of epigenetic regulation in coronary artery disease development and progression, offering potential avenues for the development of novel diagnostic biomarkers and therapeutic targets. Abnormal DNA methylation patterns are linked to the modulation of gene expression involved in crucial processes like lipid metabolism, inflammation, and vascular function in the context of coronary artery disease. Cell-free DNA has become invaluable in tumor biology as a liquid biopsy, while its applications in coronary artery disease are limited, but intriguing. Atherosclerotic plaque rupture causes myocardial infarction, by depriving heart muscles of oxygen, releasing cell-free DNA from dead cardiac cells, and providing a minimally invasive source to explore tissue-specific epigenetic alterations. We discussed the methodologies for studying the global methylome and hydroxy-methylome landscape, their advantages, and limitations. It explores methylome alterations in coronary artery disease, considering risk factors and their relevance in coronary artery disease genesis. The review also details the implications of MI-derived cell-free DNA for developing minimally invasive biomarkers and associated challenges.

Association of serum adiponectin levels and ADIPOQ SNP rs2241766 with breast cancer risk in Indian women.

Context: Adiponectin, an adipokine, and its gene polymorphisms have been associated with breast cancer risk in various populations. Subjects and Methods: In this study, we evaluated the association of the circulating levels of adiponectin and adiponectin gene polymorphism SNP rs2241766 with breast cancer and its clinicopathological characteristics in Indian women. A case-control study was carried out with 60 Ductal Infiltrating Breast Carcinoma patients and 60 age-matched healthy controls. Serum adiponectin levels were measured by ELISA. SNP genotyping was done by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism. Statistical Analysis: Serum adiponectin levels were compared using the Mann Whitney U test. The frequency of genotypes was compared using the Chi-square test. The odds ratio was calculated using logistic regression. Results: Lower serum adiponectin level was associated with increased risk of breast cancer in postmenopausal women (OR - 7.69; 95% CI - 2.16-27.43, P = 0.002) but not in the reproductive age group women. There was no association between adiponectin levels with the TNM stage of the tumor, histopathological grade, erbB2, and ER/PR status. The SNP rs2241766 polymorphism was not associated with breast cancer risk but the mutant genotypes TG/GG was found to be significantly associated with the lower histopathological grade of the tumor (X2 (2, N = 60) = 8.62, P = 0.01). Conclusion: Our results suggest that low serum adiponectin levels are associated with an increased risk of breast cancer in postmenopausal women. The TG/GG genotypes of SNP rs2241766 polymorphism were associated with a lower histological grade of the tumor.

Effect of Daily Vitamin D Supplementation on Serum Vitamin D Levels in Children with Epilepsy Receiving Sodium Valproate Monotherapy: A Randomized, Controlled Trial.

OBJECTIVES: To compare the change in serum vitamin D levels and to compare the changes in serum levels of calcium, phosphate, alkaline phosphatase and parathyroid hormone in vitamin D supplemented and unsupplemented groups after 3 mo. METHODS: In this randomized, parallel group, nonblinded, controlled trial, 40 children, 2-12 y of age with newly diagnosed epilepsy, and vitamin D sufficient status, and started on valproate monotherapy, were randomized into the intervention group (n = 20), which was given daily oral 600 IU vitamin D supplementation, and the control group (n = 20), which was not given any supplementation. Changes in the biochemical parameters was measured in the two groups after 3 mo. RESULTS: There was a significant reduction in the median (IQR) vitamin D levels in the control group as compared to an increase seen in the intervention group [-6.64 (-8.4, -2.65) vs. 5.66 (1.81, 7.12); p < 0.001]. In the control group, 37.5% children developed vitamin D insufficiency and 12.5% developed deficiency whereas only 5% of the intervention group developed vitamin D insufficiency (p = 0.005). There was a significant decrease in ionized calcium (p = 0.02), increase in serum phosphate (p = 0.02), and alkaline phosphatase level (p = 0.003) in the unsupplemented group as compared to the supplemented group. CONCLUSION: Vitamin D supplementation can reduce the valproate-associated decline in vitamin D levels and the negative impact on other markers of bone mineral metabolism. TRIAL REGISTRATION: TCTR20200621002, 19.06.2020, retrospectively registered.

Association, diagnostic accuracy and optimal threshold of salivary IGF-1 and vitamin DBP levels for estimation of pubertal growth spurt: A cross sectional study.

AIM: To determine the association of salivary IGF-1 and vitamin D Binding Protein with cervical vertebral maturation index (CVMI) across the pubertal stages and to determine the diagnostic accuracy and optimal threshold of these biomarkers for estimation of pubertal growth. DESIGN: Cross-sectional observational study. SETTING: Material and methods. All patients in the age group of 8-23 years from the Outpatient Department of Orthodontics and Dentofacial orthopaedics, between the period of July 2020 to December 2020 meeting the eligibility criteria were included. Lateral cephalograms obtained from the patients were divided into pre pubertal, pubertal & post pubertal groups based on CVMI by Baccetti et al. Unstimulated whole saliva was collected by a swab-based method & analyzed with ELISA. RESULTS: Ninety-four participants were divided in three stages: prebubertal (30), pubertal (33), post pubertal (31). A significant difference was observed in the salivary IGF-1 & DBP across the three stages. Post-hoc test revealed significantly higher mean salivary IGF-1 & DBP in pubertal group than in pre & post-pubertal group. Receiver operator characteristic curve revealed excellent diagnostic accuracy for salivary IGF-1with areas under the curve (AUC) of 0.962, satisfactory for vitamin DBP with AUC of 0.831 and poor diagnostic accuracy for age with AUC of 0.536. Youden index revealed the optimal threshold to be 3.96ng/ml and 124.13pg/ml for salivary IGF-1 and vitamin DBP respectively. CONCLUSION: The levels of Salivary IGF-1 and Vitamin DBP increased during C3 and C4 stages. Compared to vitamin DBP diagnostic accuracy of salivary IGF-1 was excellent and an optimal threshold of 3.96ng/ml can be utilized to distinguish pubertal & non-pubertal participants.

Inflammatory markers in geriatric anemia: A study from North India.

Background: Inflammation has several effects in the geriatrics with reference to iron deficiency anemia (IDA), anemia of chronic disease (ACD), and unexplained anemia (UA). Whether hyperinflammation is part of their pathogenesis or just incidental is unknown. Data are limited regarding inflammatory patterns in IDA, ACD, and UA in anemic geriatrics and inflammation as a component of UA. There is little known about the overlap of inflammation between ACD and UA. Objective: The study was undertaken to find the proportion of anemic geriatric patients, aged ≥60 years with raised serum levels of inflammatory markers and their study within IDA, ACD, and UA. Materials and Methods: Seventy-five anemic geriatric patients were evaluated for raised serum levels of inflammatory markers: high sensitive C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-8 (IL-8) along with serum ferritin (SF). Results: Raised markers were seen in 94.7% of anemic geriatric patients.IL-8 was raised most frequently followed by TNF-α, IL-6, hsCRP, and SF. No distinct inflammatory profile could be elicited between ACD and UA. The hyperinflammatory profile irrespective of the underlying etiology of geriatric anemia suggests that aging per se is pro-inflammatory state. Conclusion: Geriatric anemia can be thought to develop on background of subclinical low-grade inflammation along with superimposed nutritional deficiencies or chronic diseases.

Effect of prasugrel versus ticagrelor on coronary microcirculation in patients undergoing pharmacoinvasive strategy - acute and short-term results.

INTRODUCTION: Both ticagrelor and prasugrel are class I recommendations for treatment of ST-elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI) [ 1 ]. But clinical outcomes with the two drugs are conflicting which might be due to differential effects on coronary microcirculation. No study to date had compared the effects of prasugrel or ticagrelor on coronary microcirculation in patients undergoing pharmacoinvasive PCI (pPCI). AIM AND OBJECTIVE: To compare the effects of prasugrel and ticagrelor on coronary microcirculation in STEMI patients undergoing pPCI as assessed by Myocardial Blush Grade (MBG). The secondary aim was to assess flow in the infarct-related artery by corrected thrombolysis in myocardial infarction (TIMI) frame count (cTFC) and whether a differential effect if detected on coronary microcirculation translated in improvement in left ventricular ejection fraction assessed at 6 months. MATERIAL AND METHODS: A total of 240 patients with STEMI were evaluated in this open-label randomized control trial who initially underwent thrombolysis and later PCI (from 24 to 48 h) post-successful thrombolysis. The study subjects were randomized to receive either ticagrelor ( n  = 120) or prasugrel ( n  = 120) in 1 : 1 ratio 2 h prior to elective PCI. Patients underwent PCI according to standard protocol and post-procedure cTFC and MBG were compared. Patients were also followed up for 6 months to compare ejection fractions in both groups. We also assessed the effect of the two drugs on bleeding complications during hospitalization and over 6-month follow-up period. RESULTS: There were no significant differences between the two groups with respect to baseline characteristics. Prasugrel administration resulted in higher MBG Grade 3 (50.86% vs 33.89%, P  = 0.012) and lower cTFC (17.14 ±â€…4.08 vs 19.3 ±â€…4.06, P  < 0.01). Improvement in ejection fraction was significantly higher with prasugrel compared to ticagrelor (10.29% ± 15.2 vs 4.66% ± 13.5, P  = 0.003). Bleeding events at 6 months follow-up according to TIMI classification were similar in both the groups (11.86% vs 6.9%, P  = 0.39). CONCLUSION: Prasugrel produces greater improvement in coronary microcirculation than Ticagrelor resulting in improved myocardial salvage in patients of STEMI undergoing pPCI.

Diagnostic utility of urine neutrophil gelatinase-associated lipocalin and renal resistive index in patients of decompensated cirrhosis with acute kidney injury.

BACKGROUND: The differentiation between types of acute kidney injury(AKI) in decompensated cirrhosis(DC) patients in clinical practice is done by clinical adjudication. Biomarkers have good diagnostic accuracy for predicting acute tubular necrosis(ATN), however they are not available routinely. AIMS: We compared the diagnostic accuracy of urine neutrophil gelatinase-associated lipocalin(UNGAL) and renal resistive index(RRI) in predicting type of AKI among DC patients. METHODS: Consecutive DC patients with AKI stage≥1B seen between June/2020 to May/2021 were evaluated. UNGAL levels and RRI were measured at diagnosis of AKI(Day 0) and 48hrs(Day 3) after volume expansion. Diagnostic accuracy of UGNAL and RRI was compared for differentiating ATN and non-ATN AKI by area under receiver operating characteristic curve(AUROC), using clinical adjudication as gold standard. RESULTS: 388 DC patients were screened, 86 patients(Pre-renal AKI[PRA] n=47,55%; Hepatorenal syndrome[HRS] n=25,29%;ATN n= 14,16%) were included. The AUROC of UNGAL for differentiating ATN-AKI and non-ATN AKI at day 0 was 0.97(95%CI, 0.95-1.0) and on day 3 was 0.97(95%CI, 0.94-1.0). The AUROC of RRI for differentiating ATN and non-ATN AKI at day 0 was 0.68(95%CI, 0.55-0.80) and on day 3 was 0.74(95%CI, 0.63-0.84). CONCLUSION: UNGAL has an excellent diagnostic accuracy in predicting ATN-AKI in DC patients both at day 0 and 3.

Natural History of Asymptomatic Walled-off Necrosis in Patients With Acute Pancreatitis.

Background and objectives Studies on the natural history of asymptomatic walled-off necrosis (WON) in acute pancreatitis (AP) are scarce. We conducted a prospective observational study to look for the incidence of infection in WON. Material and methods In this study, we included 30 consecutive AP patients with asymptomatic WON. Their baseline clinical, laboratory, and radiological parameters were recorded and followed up for three months. Mann Whitney U test and unpaired t-tests were used for quantitative data and chi-square and Fisher's exact tests were used for qualitative data analysis. A p-value <0.05 was considered significant. Receiver operating characteristic curve (ROC) analysis was done to identify the appropriate cutoffs for the significant variables. Results Of the 30 patients enrolled, 25 (83.3%) were males. Alcohol was the most common etiology. Eight patients (26.6%) developed an infection on follow-up. All were managed by drainage either percutaneously (n=4, 50%) or endoscopically (n=3, 37.5%). One patient required both. No patient required surgery and there was no mortality. Median baseline C-reactive protein (CRP) was higher in infection group 76 (IQR=34.8) mg/L vs asymptomatic group, 9.5 mg/dl (IQR=13.6), p<0.001. IL-6 and tumor necrosis factor (TNF)-alpha was also higher in the infection group. The size of the largest collection (157.50±33.59 mm vs 81.95±26.22 mm, P<0.001) and CT severity index (CTSI) (9.50±0.93 vs 7.82±1.37, p<0.01) were also higher in infection group as compared to the asymptomatic group. ROC curve analysis of baseline CRP (cutoff 49.5mg/dl), size of WON (cutoff 127mm) and CTSI (cutoff of 9) showed AUROC (area under ROC) of 1, 0.97, and 0.81 respectively for the future development of infection in WON. Conclusion Around one-fourth of asymptomatic WON patients developed an infection during three-months follow-up. Most patients with infected WON can be managed conservatively.

Genetic aberration analysis of mitochondrial respiratory complex I implications in the development of neurological disorders and their clinical significance.

Growing neurological diseases pose difficult challenges for modern medicine to diagnose and manage them effectively. Many neurological disorders mainly occur due to genetic alteration in genes encoding mitochondrial proteins. Moreover, mitochondrial genes exhibit a higher rate of mutation due to the generation of Reactive oxygen species (ROS) during oxidative phosphorylation operating in their vicinity. Among the different complexes of Electron transport chain (ETC), NADH: Ubiquinone oxidoreductase (Mitochondrial complex I) is the most important. This multimeric enzyme, composed of 44 subunits, is encoded by both nuclear and mitochondrial genes. It often exhibits mutations resulting in development of various neurological diseases. The most prominent diseases include leigh syndrome (LS), leber hereditary optic neuropathy (LHON), mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS), myoclonic epilepsy associated with ragged-red fibers (MERRF), idiopathic Parkinson's disease (PD) and, Alzheimer's disease (AD). Preliminary data suggest that mitochondrial complex I subunit genes mutated are frequently of nuclear origin; however, most of the mtDNA gene encoding subunits are also primarily involved. In this review, we have discussed the genetic origins of neurological disorders involving mitochondrial complex I and signified recent approaches to unravel the diagnostic and therapeutic potentials and their management.

Implication of gut microbes and its metabolites in colorectal cancer.

BACKGROUND: Colorectal cancer (CRC) is the third most common cancer with a significant impact on loss of life. In 2020, nearly 1.9 million new cases and over 9,35,000 deaths were reported. Numerous microbes that are abundant in the human gut benefit host physiology in many ways. Although the underlying mechanism is still unknown, their association appears to be crucial in the beginning and progression of CRC. Diet has a significant impact on the microbial composition and may increase the chance of getting CRC. Increasing evidence points to the gut microbiota as the primary initiator of colonic inflammation, which is connected to the development of colonic tumors. However, it is unclear how the microbiota contributes to the development of CRCs. Patients with CRC have been found to have dysbiosis of the gut microbiota, which can be identified by a decline in commensal bacterial species, such as those that produce butyrate, and a concurrent increase in harmful bacterial populations, such as opportunistic pathogens that produce pro-inflammatory cytokines. We believe that using probiotics or altering the gut microbiota will likely be effective tools in the fight against CRC treatment. PURPOSE: In this review, we revisited the association between gut microbiota and colorectal cancer whether cause or effect. The various factors which influence gut microbiome in patients with CRC and possible mechanism in relation with development of CRC. CONCLUSION: The clinical significance of the intestinal microbiota may aid in the prevention and management of CRC.

Teerakanchana's equation transcends over 12 other LDL-C quantification formulae in the North Indian population.

BACKGROUND: Over the last 3 decades, there has been a steady rise in global mortality due to cardiovascular diseases (CVDs). Therefore, timely diagnosis of CVDs is paramount. Low-Density Lipoprotein-cholesterol (LDL-C) in blood serum is one of the biomarkers for the risk assessment of CVDs, measured by direct assays and indirect approaches. The indirect method of LDL-C quantification by Friedewald's formula is more widely used in Indian clinical settings than direct assays due to its time and cost-effectiveness. However, its accuracy has been questioned for a long. We tried to find the formula that work in best agreement with the direct method. METHODS: Lipid profiling was done following a direct homogenous method (LDL-C_M) and LDL-C was calculated by 13 formula. The LDL-C values were categorized into groups based on TG. All the formula were statistically correlated with LDL-C_M. RESULTS: Teerakanchana's formula has shown a strong positive correlation (r = 0.914) and good agreement M (Lin's CCC = 0.929, CI = 0.918-0.939) with LDL-C_M, followed by Vujovic's formula (r = 0.903, Lin's CCC = 0.925, CI = 0.912-0.936). CONCLUSIONS: Teerakanchana and Vujovic's formula may replace Friedewald to quantify LDL-C in the public health care settings of the North Indian population.
