Team based collaborative care model, facilitated by mHealth enabled and trained nurses, for management of heart failure with reduced ejection fraction in India (TIME-HF): design and rationale of a parallel group, open label, multi-centric cluster randomised controlled trial.

Background: Heart failure (HF) is a debilitating condition associated with enormous public health burden. Management of HF is complex as it requires care-coordination with different cadres of health care providers. We propose to develop a team based collaborative care model (CCM), facilitated by trained nurses, for management of HF with the support of mHealth and evaluate its acceptability and effectiveness in Indian setting. Methods: The proposed study will use mixed-methods research. Formative qualitative research will identify barriers and facilitators for implementing CCM for the management of HF. Subsequently, a cluster randomised controlled trial (RCT) involving 22 centres (tertiary-care hospitals) and more than 1500 HF patients will be conducted to assess the efficacy of the CCM in improving the overall survival as well as days alive and out of hospital (DAOH) at two-years (CTRI/2021/11/037797). The DAOH will be calculated by subtracting days in hospital and days from death until end of study follow-up from the total follow-up time. Poisson regression with a robust variance estimate and an offset term to account for clustering will be employed in the analyses of DAOH. A rate ratio and its 95% confidence interval (CI) will be estimated. The scalability of the proposed intervention model will be assessed through economic analyses (cost-effectiveness) and the acceptability of the intervention at both the provider and patient level will be understood through both qualitative and quantitative process evaluation methods. Potential Impact: The TIME-HF trial will provide evidence on whether a CCM with mHealth support is effective in improving the clinical outcomes of HF with reduced ejection fraction in India. The findings may change the practice of management of HF in low and middle-income countries.

Protective effect of theaflavin on glycoprotein components and TCA cycle enzymes in high-fat diet and streptozotocin-induced diabetic rats.

BACKGROUND: Theaflavins are major polyphenols in black tea which is the most widely consumed tea in the world. They possess a broad spectrum of biological activities, such as antioxidant, anti-tumor, anti-inflammatory, and cardio-protective effects. The present study was aimed to evaluate the protective effect of theaflavin on glycoprotein content and tricorboxylic acid cycle enzymes in high-fat diet and streptozotocin-induced diabetic rats as there was no study on this aspect. Diabetes was induced in male albino Wistar rats by feeding them with high-fat diet and injecting them intraperitoneally with streptozotocin (40 mg/kg b.wt). RESULTS: Different doses of theaflavin (25, 50, and 100 mg/kg b.wt /day) were administered orally to high-fat diet and streptozotocin-induced diabetic rats for 30 days for fixing the glucose lowering dose. However, the dose at 100 mg/kg b.wt showed a significant reduction in the levels of plasma glucose and Homeostatic Model Assessment of Insulin Resistance with concomitant elevation of insulin when compared to the other two doses (25 and 50 mg/kg b.wt). Hence, 100 mg/kg b.wt was fixed as an effective dose and used for further analysis. Theaflavin administration restored the altered glycosylated hemoglobin, hemoglobin and glycoproteins (Hexose, hexosamine, fucose, and sialic acid) and TCA cycle enzymes (isocitrate dehydrogenase, α-ketoglutarate dehydrogenase, succinate dehydrogenase, and malate dehydrogenase) near the normal levels by correcting hyperglycemia. Improved histological changes were observed in the pancreas of diabetic rats upon treatment with theaflavin which supported the biochemicals investigated. CONCLUSION: The effect produced by the theaflavin on various parameters was comparable to that of metformin-a reference antidiabetic drug. These findings suggest that theaflavin can replace the commercial drugs which could lead to reduction in toxicity and side effect caused by the later as well as reduce the secondary completions.

Antioxidant potential of theaflavin ameliorates the activities of key enzymes of glucose metabolism in high fat diet and streptozotocin - induced diabetic rats.

Objectives: The present study was to evaluate the effect of theaflavin on the activities of key enzymes of carbohydrate metabolism in high fat diet and streptozotocin - induced diabetic rats. Methods: Diabetes was induced in male albino Wistar rats by feeding them with high fat diet comprising of standard laboratory rat chow 84.3%, lard 5%, egg yolk powder 10%, cholesterol 0.2% and bile salt 0.5% for 2 weeks. After 2 weeks, the animals were kept in an overnight fast and injected with low dose of streptozotocin (40 mg/kg b.w). Results: Theaflavin (100 mg/kg b.w /day) was administered orally to diabetic rats for 30 days. At the end of the experimental period, diabetic control rats showed significant increase in plasma glucose, homeostatic model assessment of insulin resistance (HOMA-IR), glycosylated hemoglobin (HbA1c) with concomitant decrease in plasma insulin, total hemoglobin and body weight. The activities of key enzymes of carbohydrate metabolism, lipid peroxidation markers, antioxidant enzymes, glycogen content and glycogen synthase and glycogen phosphorylase were also altered in diabetic rats. Discussion: Oral administration of theaflavin to diabetic rats significantly ameliorated all the biochemical alterations to near normal levels. The results of the present study suggest that theaflavin exhibits antidiabetic effect through its antioxidant activity.

A Study on Spectrum of Hepatobiliary Dysfunctions and Pattern of Liver Involvement in Dengue Infection.

INTRODUCTION: The most common arthropod-borne viral (arboviral) disease in humans is dengue. It is transmitted by female Aedes mosquitoes. These mosquitoes are widely distributed in subtropical and tropical areas of the world. Study of dengue infection and its complications are rare from countries like India. AIM: In this prospective observational cross-sectional study, we intended to assess the frequency and degree of hepatobiliary dysfunction in adult patients with dengue infection presenting to a tertiary-care medical facility. MATERIALS AND METHODS: The details of all patients with serologically proved dengue fever admitted to a tertiary care hospital in eastern India from July 2014 to June 2015 were prospectively reviewed. We collected data including routine blood count, Liver Function Test (LFT), Prothrombin Time (PT), Activated Partial Prothrombin Time (APTT), abdominal ultrasonography from 110 patients. RESULTS: The maximum number of cases were seen in the age group between 46 years and 61 years and of all cases 55.5% were male and 44.5% were female. Pain abdomen and vomiting were the commonest presenting complaints next to fever which was present in all the cases. Elevated liver enzymes, abnormal values of PT and APTT, thrombocytopenia were observed more commonly in Dengue Shock Syndrome (DSS). Gall bladder wall thickening, thrombocytopenia were seen more commonly in both DSS and Dengue Haemorrhagic Fever (DHF). Plasma leakage such as ascites and pleural effusion on USG were seen more frequently in patients with DHF (76.9% and 73.1%) followed by DSS (72% and 68%) and DF (33.9% and 32.2%). CONCLUSION: Hepatobiliary derangement is seen more commonly in severe case of dengue infection. Early recognition of these parameters can also be used as a predictor for assessing the disease severity.

Herpes Zoster Infection Involving Mandibular Division of Trigeminal Nerve and Ramsay Hunt Syndrome with Meningitis in an Immunocompetent Patient: A Rare Association.

Herpes zoster is a unilateral painful vesicular cutaneous eruption caused by the reactivation of the Varicella zoster virus. It commonly affects the older people and immunocompromised individuals. The dermatomes from T3 to L3 are most frequently involved. Its three stages include prodromal stage, active stage and chronic stage. The common complications of the infection include post-herpetic neuralgia, Ramsay Hunt syndrome, Guillain-Barre syndrome, transverse myelitis and encephalomyelitis. This case report summarizes a very rare association of herpes zoster meningitis with the involvement of mandibular division of the trigeminal nerve and facial nerve. The patient improved with intravenous acyclovir and prednisolone treatment.

Cronkhite-Canada Syndrome: A Rare Cause of Chronic Diarrhoea in a Young Man.

A young Indian man presented with nine-month history of chronic diarrhea, occasionally mixed with blood and intermittent colicky abdominal pain. He also complained of generalized body swelling for the last three months. On examination, he had diffuse hyperpigmentation of the skin and dystrophic nail changes. Upper and lower gastrointestinal endoscopy revealed multiple sessile polyps in the stomach, small bowel, and colon and rectum. Biopsy of polyps showed adenomatous changes with stromal edema and dilated glands. Cronkhite-Canada syndrome (CCS) was diagnosed and treated with glucocorticoids and enteral nutritional supplementation. There was an associated small intestinal bacterial overgrowth (SIBO) and stool was positive for clostridium difficile toxin. After 12 weeks of treatment, the patient achieved remission. Close correlation with clinical findings, including pertinent ectodermal abnormalities, endoscopic studies, and careful examination of biopsies will ensure a timely and correct diagnosis of CCS.

Two Uncommon Causes of Guillain-Barré Syndrome: Hepatitis E and Japanese Encephalitis.

We are presenting two cases of Guillain-Barré syndrome where it is preceded by hepatitis E virus (HEV) and Japanese encephalitis virus (JEV) infection, respectively. Our first case is a forty-three-year-old nondiabetic, nonhypertensive female who was initially diagnosed with acute HEV induced viral hepatitis and subsequently developed acute onset ascending quadriparesis with lower motor neuron type of bilateral facial nerve palsies and respiratory failure. Second patient was a 14-year-old young male who presented with meningoencephalitis with acute onset symmetric flaccid paraparesis. After thorough investigations it was revealed as a case of Japanese encephalitis. Our idea of reporting these two cases is to make ourselves aware about this potential complication of these two common infections.

Takayasu's Arteritis with Systemic Lupus Erythematosus: A Rare Association.

We report the case of a 24-year-old nondiabetic, nonhypertensive lady with history of fatigue, dyspnoea and limb claudication. She has been diagnosed with Takayasu's arteritis. Subsequently she developed rash, alopecia, joint pain, and various other laboratory abnormalities which led to a diagnosis of SLE. Takayasu's arteritis (TA) rarely coexists with systemic lupus erythematosus (SLE). The absence of specific SLE markers in patients with TA who subsequently develop SLE suggests that the coexistence of these conditions may be coincidental. The antiphospholipid syndrome in patients with SLE may mimic the occlusive vasculitis of TA.
