RESUMEN
Aortic valve stenosis is a disease characterized by thickening and narrowing of the aortic valve (AV), most commonly due to calcification, which leads to left ventricular outflow obstruction called calcific aortic valve disease (CAVD). CAVD presents as a progressive clinical syndrome with cardiorespiratory symptoms, often with rapid deterioration. The modern-day pathophysiology of CAVD involves a complex interplay of genetic factors, chronic inflammation, lipid deposition, and valve calcification, with early CAVD stages resembling atherosclerosis. Various imaging modalities have been used to evaluate CAVD, with a recent trend of using advanced imaging to measure numerous AV parameters, such as peak jet velocity. Significant improvements in mortality have been achieved with transcatheter AV repair, but numerous therapeutics and modalities are being researched to delay the progression of CAVD. This article aims to provide a comprehensive review of CAVD, explore recent developments, and provide insights into future treatments with various novel modalities.
RESUMEN
Transthyretin amyloid cardiomyopathy (ATTR-CM) is a mutation-based genetic disorder due to the accumulation of unstable transthyretin protein and presents with symptoms of congestive heart failure (CHF) and numerous extracardiac symptoms like carpal tunnel syndrome and neuropathy. Two subtypes of ATTR-CM are hereditary and wild-type, both of which have different risk factors, gender prevalence and major clinical symptoms. Timely usage of imaging modalities like echocardiography, cardiac magnetic imaging resonance, and cardiac scintigraphy has made it possible to suspect ATTR-CM in patients presenting with CHF. Management of ATTR-CM includes appropriate treatment for heart failure for symptomatic relief, prevention of arrhythmias and heart transplantation for nonresponders. With the recent approval of tafamidis in the successful management of ATTR-CM, numerous potential therapeutic points have been identified to stop or delay the progression of ATTR-CM. This article aims to provide a comprehensive review of ATTR-CM and insights into its novel therapeutics and upcoming treatments.

Premature ventricular contractions (PVC) are a type of ventricular arrhythmias, occurring as a result of formation or reentry of an abnormal impulse in the ventricular myocardium or in the Purkinje system. PVC occurs commonly in healthy individuals and is observed in 1%-4% of the population. Several lifestyle factors like stress levels, caffeine, drugs, alcohol, nicotine, sleep, and physical exercise have been implicated in increasing the risk. Caffeine and drugs precipitate heightened cardiac stimulation, precipitating PVCs. Excessive alcohol and nicotine disturb the electrical pathways resulting in PVCs. Higher rates of PVCs have been associated with obesity. Individuals with insomnia and increased stress levels are also at an increased risk due to an imbalance in the autonomic system. Exercise is known to induce PVCs, including in healthy, asymptomatic individuals. Modification of these factors can decrease PVC risk. This article aims to provide a comprehensive review of the effects of lifestyle factors on PVC.

We present a case report of a 20-year-old male who suffered a stab injury to the left supraclavicular region, resulting in the formation of a pseudoaneurysm of the left subclavian artery. Initial endovascular management with a self-expandable covered stent graft showed promising results, but recurrence with proximal and distal end leaks necessitated further intervention. The patient's financial constraints delayed subsequent treatment, leading to worsening symptoms, including left upper limb paraparesis. Facing technical challenges due to the large size of the aneurysm and proximity to the vertebral artery, a vertebral artery confluence was performed, followed by a longer stent-graft placement to address the pseudoaneurysm successfully. This case highlights the potential advantages of endovascular approaches in complex subclavian artery injuries and emphasizes the importance of timely intervention to avoid complications and improve patient outcomes.
RESUMEN
Pancytopenia due to systemic lupus erythematosus (SLE) is rarely reported, and among those reported, it is mostly due to immunologically mediated cell destruction. Pancytopenia due to bone marrow fibrosis secondary to SLE is an extremely rare entity. Myelofibrosis secondary to SLE per se is reported only in 21 cases in the literature. Ours probably is the 22nd case report on SLE with myelofibrosis. Primary presentation of SLE with bleeding manifestation is also a rare phenomenon. Partial to complete regression of myelofibrosis is noted following treatment in secondary myelofibrosis caused by SLE. We report a case of a woman in her late 40s who presented to us with bleeding manifestations of petechial rash and menorrhagia, which on further evaluation showed pancytopenia due to myelofibrosis secondary to SLE. Our case underlines multiple features like primary bleeding manifestation and regression of myelofibrosis following treatment which is rarely reported in association with SLE.

Subcutaneous entomophthoromycosis is an infection caused by saprophytic, ubiquitous and highly opportunistic fungal pathogens. Individuals with immune disorders are frequently susceptible to these infections. Entomophthoromycosis is a rare fungal infection that primarily affects children andmen, and is known to cause infection in healthy individuals. Diagnosis of the disease is by demonstration of fungal elements using special stains, and the disease responds well to oral antifungal agents. Long-term antifungal agents reduce the need for surgical intervention when the disease presents as a mass. We report a case of an immunocompetent nursing mother in her 20s who presented with a soft tissue mass in her right arm. It was diagnosed as subcutaneous entomophthoromycosis and treated with long-term fluconazole. The lesion showed a significant reduction in size following treatment for 2 months. Subcutaneous fungal infection presenting as a mass-forming lesion in extremities may mimic a neoplasm. Fungal infection should be ruled out in inflammatory cell-rich lesions seen on histopathological examination.

Background The present study assessed the efficacy of the residential, group-based, intensive holistic lifestyle intervention on glycaemic control. Materials and methods A one-group pre and post-intervention study was conducted among 145 people with diabetes for a period of one year from February 2019 to January 2020. The study population underwent "Brahma Kumaris Raja Yoga lifestyle" intervention. Outcome variables were changes in HbA1c levels and anthropometric parameters (like weight, BMI, etc.). Paired t-test was used to compare normally distributed numeric variables. Results The mean age was 52.39±5.79 years, with a male-female ratio close to 1:1. Mean HbA1c at baseline was 9.06±2.1%. The mean weight and BMI were 71.03±12.84 kg and 28.28±4.83kg/m2, respectively. Mean HbA1c value had shown a reduction of 1.60% (95%CI 1.17 to 1.90, p <0.001) at three months and 1.58% (95% CI 1.13-1.87, p<0.001) reduction at a six-month follow-up. Between the third and sixth months, there was no significant change in the HbA1c value. Mean weight reduced by 0.79 kg (95% CI 0.08-1.08, p=0.023) at six-month follow-up and mean BMI decreased by 0.31 units from baseline to three months (95% CI 0.05-0.56, p=0.017). A statistically significant reduction was observed in waist circumference at the third month (MD=1.61 95% CI =0.95 to 2.28, P<0.001) and sixth month (MD=1.53, 95% CI 0.82-2.25, p<0.001) follow-up. Conclusion This residential, group-based, intensive holistic lifestyle intervention showed a significant decrease in HbA1c levels and anthropometric parameters at three- and six-months follow-up, thereby improving the overall health and wellbeing of people with diabetes.
RESUMEN
INTRODUCTION: Despite the recent developments in the biology of addiction, a significant part of relapse and its management is still influenced by psychosocial factors and the interplay between them. This study aims at finding the extent of association of various psychosocial factors with relapse in patients of alcohol dependence. MATERIALS AND METHODS: It is a cross-sectional study of two groups of alcohol dependence patients: abstinence (n = 31) and relapse (n = 35). Demographic, clinical, and psychosocial variables were compared between the two groups. Statistical analyses were aimed at finding the extent of association between various factors and relapse. RESULTS: Demographic variables such as family history of substance dependence (odds ratio [OR] =2.09; confidence interval [CI] =0.74-5.90) and past history of ≥2 relapses (OR = 2.71; CI = 0.83-8.87) were associated with relapse in alcohol dependence. Clinical variables such as younger age of onset of dependence (Mean difference = -3.93; 95% CI = -7.66 - -0.21; P = 0.038) and shorter time to develop dependence (Mean difference = -3.08; 95% CI = -5.53 --0.63; P = 0.014) were significantly associated with relapse. Of the psychosocial variables, coping behavior (OR = 6.54; CI = 1.17-36.74) had the highest association with relapse followed by relapse precipitants (OR = 1.42; CI = 1.16-1.74). CONCLUSION: Coping behaviors to adverse situations have greater association with relapse among psychosocial variables than the number of high-risk situations a patient experiences. Interventions targeted at improving coping skills can help patients stay abstinent.
RESUMEN
CONTEXT: Hyperlipidemia is known to be a major risk factor for the development of cardiovascular diseases (CVDs) which include atherosclerosis, coronary heart disease, and stroke. Although there are a large number of anti-hyperlipidemic drugs available, unfortunately, they all have side effects. OBJECTIVE: Terminalia chebula Retz. (Combretaceae) is a plant used to treat cardiac disorders in the traditional Ayurveda medicine in India. The objective of this study was to assess the anti-hyperlipidemic properties of a methanol (MeOH) bark extract of T. chebula. MATERIALS AND METHODS: Acute toxicity studies were performed according to the Organisation for Economic Cooperation and Development (OECD) guideline no. 423 using various doses (5, 50, 300, and 2000 mg/kg) of T. chebula bark. Anti-hyperlipidemic effect of MeOH bark extract of T. chebula at doses of 200, 400, and 600 mg/kg and fasting glucose levels after treatment with MeOH bark extract of T. chebula at doses of 200, 400, and 600 mg/kg were analyzed using commercially available kits. RESULTS: Acute toxicity studies did not show any morbidity and mortality at various doses. The MeOH extract of T. chebula bark at doses of 200, 400, and 600 mg/kg significantly lowered serum cholesterol and triglyceride levels. Moreover, the extract of T. chebula and the positive control atorvastatin-treated groups of animals showed a significant increase in the serum high-density lipoprotein (HDL) cholesterol levels in diet-induced hypercholesterolemic animals. CONCLUSION: The overall results confirm that the bark extract of T. chebula possesses significant anti-hyperlipidemic activity.
