Tacrolimus Concentration/Dose Ratio: A Tool for Guiding Tacrolimus Dosage Post-renal Transplantation.

Background The calcineurin inhibitor, Tacrolimus (Tac), exhibits variable absorption and undergoes first-pass metabolism when administered orally. The narrow therapeutic window and individual variability of this immunosuppressive agent make therapeutic drug monitoring essential. We hypothesized that the Tac metabolism rate - defined as the blood concentration normalized by its daily dose (the C/D ratio) - is associated with post-renal transplant (RTx) function.

Clinical profile of 1208 newly diagnosed colorectal cancer patients in Tamil Nadu-A multi-centric survey.

Background: An increasing incidence of colorectal cancer (CRC) is being reported in developing countries, including India. Most Indian studies on CRC are retrospective and single-centered. The present study is an attempt to understand the current clinical profile and stage of newly diagnosed CRCs across multiple centers in Tamil Nadu, India.

Eagle Syndrome: An Unusual Cause of Axial Neck Pain: A Case Report.

Case: A 42-year-old woman presented with left-sided axial neck pain with radiation behind left ear of 3 months unresponsive to conservative treatment. As clinical examination revealed tenderness anterior to the mastoid process, she was referred to an otolaryngologist. Computed tomography showed an elongated left styloid process.

Systematic review and meta-analysis of early aortic valve replacement versus conservative therapy in patients with asymptomatic aortic valve stenosis with preserved left ventricle systolic function.

Background: A quarter of patients with severe aortic stenosis (AS) were asymptomatic, and only a third of them survived at the end of 4 years. Only a select subset of these patients was recommended for aortic valve replacement (AVR) by the current American College of Cardiology/American Heart Association guidelines. We intended to study the effect of early AVR (eAVR) in this subset of asymptomatic patients with preserved left ventricle function.

Left bundle branch pacing lead for sensing ventricular arrhythmias in implantable cardioverter-defibrillator: A pilot study (LBBP-ICD study).

Background: Left bundle branch pacing (LBBP) has been suggested as an alternative modality for biventricular pacing in cardiac resynchronization therapy (CRT)-eligible patients. As it provides stable R-wave sensing, LBBP has been recently used to provide sensing of ventricular arrhythmia in patients receiving implantable cardioverter-defibrillator (ICD) with CRT.

Objective: The aim of this study was to analyze the long-term safety and efficacy of the LBBP lead for appropriate detection of ventricular arrhythmia and delivery of antitachycardia pacing (ATP) in patients requiring defibrillator therapy with CRT.

Mycobacterium abscessus endocarditis post cardiac cathetrisation-a case report and review of 25 cases (2001-2023).

47 year male underwent percutaneous transluminal coronary angioplasty elsewhere, developed fever after two days, and treated empirically in various hospitals for the subsequent two months. Echocardiography showed vegetation in aortic valve and blood cultures were negative. He was then diagnosed as a case of endocarditis due to M.

Cerebral phaeohyphomycosis due to Cladophialophora bantiana: case report and systematic review of cases.

Purpose: Cladophialophora bantiana is a wonted melanized fungus causing brain abscess. In past many cases were reported from Asia, particularly from India. Of late, there is a rise in cases in places besides Asia and hence a review of the cases is warranted.

Arrhythmic Risk in Biventricular Pacing Compared With Left Bundle Branch Area Pacing: Results From the I-CLAS Study.

Background: Left bundle branch area pacing (LBBAP) may be associated with greater improvement in left ventricular ejection fraction and reduction in death or heart failure hospitalization compared with biventricular pacing (BVP) in patients requiring cardiac resynchronization therapy. We sought to compare the occurrence of sustained ventricular tachycardia (VT) or ventricular fibrillation (VF) and new-onset atrial fibrillation (AF) in patients undergoing BVP and LBBAP.

Methods: The I-CLAS study (International Collaborative LBBAP Study) included patients with left ventricular ejection fraction ≤35% who underwent BVP or LBBAP for cardiac resynchronization therapy between January 2018 and June 2022 at 15 centers.

Association of dietary patterns and health outcomes by spatial regression analysis of nationally representative survey data from India.

Background: Our aim was to study the regional differences in dietary patterns in India and their association with population-level nutrition-related health indicators such as the prevalence of anemia, overweight, undernutrition, and hyperglycemia.

Objectives: To identify and characterize the dietary patterns from publicly available nationally representative survey data on food consumption conducted by the National Sample Survey Office (NSSO) to study the regional differences in dietary patterns.

Methods: Dietary patterns were identified by factor analysis of per capita food consumption data from the household consumer expenditure survey (2011).

Pulmonary tuberculosis and neurologic melioidosis coinfection-first case report from Madurai.

Despite tuberculosis and melioidosis being endemic in many countries, coinfections are unusual. Only fourteen cases of tuberculosis melioidosis coinfections have been reported. To the best of our knowledge, this is the first case of coinfection of tuberculosis and neurologic melioidosis.

Burkholderia cepacia infections at sites other than the respiratory tract: A large case series from a tertiary hospital in Madurai.

Sparsely reported extrapulmonary Burkholderia cepacia complex (Bcc) infections highlights the importance of this study. This was a retrospective chart review of 37 patients with extrapulmonary Bcc infections admitted between December 2019 and July 2022 in a tertiary hospital. Males accounted for 70% of cases.

Low Serum Hepcidin Levels in Patients with Ulcerative Colitis - Implications for Treatment of Co-existent Iron-Deficiency Anemia.

Ulcerative colitis (UC) is often associated with anemia. Hepcidin, the central regulator of iron homeostasis, is known to be induced by inflammation and suppressed by anemia. It is not clear how hepcidin is affected in those with UC, when both inflammation and anemia may co-exist.

Traumatic mucormycosis caused by Apophysomyces species - A case series.

Background: Apophysomyces species are emerging as the second most common agent of mucormycosis in India. It is worrisome as it affects predominantly immunocompetent host unlike other Mucorales. Unfortunately, the most common presentation is necrotising fasciitis which can be overlooked as bacterial infection.

Case series of aspergillus spondylodiscitis from a tertiary care centre in India.

Aspergillus spondylodiscitis is a rare entity reported in the literature. In tuberculosis endemic regions like India, more often it could be misdiagnosed as tuberculous spondylodiscitis. Herein we report a case series of three patients with Aspergillus spondylodiscitis presenting with chronic low backpain and clinically diagnosed as tuberculosis spine.

The Effectiveness of Adjuvant Attangaogam (Athanam) Yoga Asana-Pranayamam Practices With Regard to Biochemical, Inflammatory, and Hematological Markers Among COVID-19 Patients at a Tertiary Care Hospital in Southern Tamilnadu.

Background and objective Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a highly contagious infectious disease that has affected many countries globally. Attangaogam, known in Sanskrit as "Ashtanga yoga", is a practice associated with the spiritual and cultural heritage of India whose origins can be traced back to the very dawn of civilization; the practice of yoga promotes health, healing, and longevity. This study aimed to analyze the effects of Attangaogam (Athanam) yoga asana-Pranayamam practice on biochemical, inflammatory, and hematological markers in the management of COVID-19.
