Clinical and Angiographic Profiles of Myocardial Infarction in a Young South Indian Population.

Introduction Myocardial infarction (MI) in young South Indians presents a shifting epidemiological landscape, challenging traditional perceptions of cardiovascular diseases. This study investigates the clinical and angiographic profiles of MI in this subgroup of the population in detail, emphasizing the interaction between lifestyle, environmental, and genetic factors that contribute to the incidence of MI in younger people. Methodology Utilizing a descriptive observational design, the study analyzed data from 70 young adults (aged 18-45 years) admitted to Frontier Lifeline Hospital, Chennai, with acute MI over six months. Patient demographics, clinical characteristics, and angiographic findings were collected and analyzed using standardized protocols. Statistical analysis employed chi-square tests and subgroup analyses to assess associations and differences between diabetic and non-diabetic patients. Results The study revealed a predominance of males (84.29%) among MI cases, with ST-elevation myocardial infarction (STEMI) being the most common presentation (52.86%). Anterior wall involvement was prevalent (50%), and left ventricular systolic dysfunction (LVSD) was observed in the majority (67%) of patients. Chest pain (87%) was the predominant symptom, and diabetes (47%) and hypertension (47%) were the risk variables that were most common. Angiographically, the left anterior descending artery (LAD) was often affected (51%), with single-vessel disease predominating (41.43%). Conclusion The findings underscore the significance of early detection and intervention strategies for MI in young South Indians. Gender-specific risk assessment, prompt diagnosis, and tailored treatment approaches are imperative. The high prevalence of LVSD highlights the burden of cardiac morbidity, particularly in diabetic individuals. Lifestyle modifications and weight management interventions are crucial for MI prevention. This study provides insights into the frequency and features of MI in young South Indians, emphasizing the importance of collaborative efforts for early identification and control of modifiable risk factors to mitigate the burden of coronary artery disease (CAD) in this population subset.

Undiagnosed rheumatic carditis causing sudden death in a young adult: A case report and review.

Acute rheumatic fever-related acquired heart disease in children and young adults is a worldwide issue, but it poses a serious public health threat in developing nations like India. We present a case report of a young adult who collapsed suddenly during a routine walk and was declared dead in an emergency ward on arrival. There was no significant past medical history. On autopsy, massive cardiomegaly and a "butter and bread" appearance of the pericardium, along with findings suggestive of mitral stenosis and aortic regurgitation, raised suspicion about rheumatic heart disease. Rheumatic carditis was confirmed by a microscopic examination that showed Aschoff bodies in the left ventricle, mitral valve and interventricular septum, in addition to uncommon Anitschkow cells in the left ventricle. A sudden death due to undiagnosed rheumatic carditis causing such massive cardiomegaly is rare. This case highlights the need to keep rheumatic carditis as a cause of sudden death.

A direct saphenous nerve block in TKA: A surgeon friendly technique! Cadaveric study.

Introduction: Effective management of postoperative pain in total knee arthroplasty (TKA) poses a significant challenge for surgeons. Achieving rapid recovery without pain and promoting early ambulation in immediate and early postoperative periods are essential for patient satisfaction. There are many pain management protocols including nerve blocks. Nerve blocks procedures were done using USG and anaesthetist dependent. This cadaveric study aimed to define the VMO (Vastus medialis obliquus) triangle to target the 'safe zone' of the saphenous nerve during TKA: A surgeon's friendly technique. Methods: 12 formalin-fixed embalmed cadaveric lower limbs were dissected to explore anatomy, trajectory, the relation of saphenous nerve and measured the distances from the nearby palpable bony landmarks. Results: The average distance to target the saphenous nerve i.e target point from midpoint of superior pole of the patella was 10.6cm, the average angle to target the saphenous nerve is the angle between the line joining the medial epicondyle to the midpoint of the superior pole of the patella is found to be 64.2°. The average distance from midpoint of superior pole patella to medial epicondyle is found to be 8.1cm. Therefore, triangle so formed using these three points (1. Medial epicondyle, 2. The midpoint of superior pole of the patella, 3. Target point of the saphenous nerve) is called a VMO triangle. Conclusions: The saphenous nerve course, relations, and the distances from intraoperative bony landmarks for the VMO triangle during TKA which is a reproducible triangle so may be useful for arthroplasty surgeons to achieve successful saphenous nerve block and to avoid related complications during total knee arthroplasty (TKA).

Sudden death due to spontaneous rupture of the right atrium in the setting of chronic lung disease: A case report and review.

Sudden death from haemopericardium as a result of a right atrial rupture is uncommon, most particularly when this occurs spontaneously without any prior trauma or evidence of atrial wall pathology. The deceased was a 32-year-old man. At lunchtime his symptoms of unease, giddiness and unconsciousness began and within 45 minutes he arrived at the hospital. His vitals could not be recorded in the emergency department, and after CPR, he was pronounced dead. At autopsy, an isolated right atrial rupture, without any disease of the heart wall, was discovered. The right atrium has the weakest wall and is frequently the site of spontaneous rupture brought on by increased intraluminal pressure. Both liquid blood and clotted blood were found in the pericardial cavity. Low atrial pressure encourages clot formation because it causes considerably slower blood entry into the pericardium at the time of atrial rupture compared with entry at the time of ventricular rupture. Evidence of chronic lung disease was found which explains the raised intraluminal pressure of the heart chambers. Even with no history of trauma or myocardial infarction, the Beck triad - an engorged neck vein, a muffled heart sound, and low blood pressure - should alert the emergency room staff to the possibility of cardiac tamponade because, in a very unlikely scenario, spontaneous cardial wall rupture might occur.

SIRT1 mediates breast cancer development and tumorigenesis controlled by estrogen-related receptor ß.

Silent mating type information regulation 2 homolog 1 (SIRT1) is a class III histone deacetylase (HDAC) that is NAD + dependent and essential for metabolism, senescence, and cell survival. SIRT1 is overexpressed in several cancers, including breast cancer. SIRT1 is a well-known target gene of the estrogen receptor alpha (ER alpha) and is closely related to ER alpha deacetylation. Transcription factor Estrogen-related receptors (ERRs) share sequence homology with ERs in the DNA-binding domain, therefore, the possibility of sharing target genes between them is high. Our current research aims to gain insight into the function of ERRß in regulating the activity of SIRT1 during the progression of breast cancer. ER-positive (ER + ve) breast cancer cells and tissues had considerably enhanced SIRT1 expression. Six potential ERRE sites were identified by analysis of the 5' upstream region of SIRT1, and both in vitro and in vivo experiments supported their presence. We found SIRT1 to be up-regulated in ERRß overexpressed ER + ve breast cancer cells. Furthermore, our findings suggested that ectopic production of ERR and PCAF would increase SIRT1 activity. Our findings also indicated that ectopic production of ERRß and PCAF increased SIRT1 activity. With sufficient evidence demonstrating the substantial involvement of SIRT1 in cell proliferation, migration, and colony formation capability, we were also able to illustrate the tumorigenic role of SIRT1. Overall, our findings highlight SIRT1's tumorigenic influence on breast cancer and suggest that SIRT1 inhibitors might serve as potential therapeutic drugs for the treatment of breast cancer.

Electrochemical Sensors for Detection of Phytomolecules: A Mechanistic Approach.

High demand and ongoing technological advancements have created a market for sensors that is both varied and rapidly evolving. Bioactive compounds are separated systematically to conduct an in-depth investigation, allowing for the profiling or fingerprinting of different Plantae kingdoms. The profiling field is significant in elucidating the complex interplay of plant traits, attributes, and environmental factors. Flexible technology advancements have enabled the creation of highly sensitive sensors for the non-destructive detection of molecules. Additionally, very specialized integrated systems that will allow multiplexed detection by integrating many hybrid approaches have been developed, but these systems are highly laborious and expensive. Electrochemical sensors, on the other hand, are a viable option because of their ability to accomplish exact compound detection via efficient signal transduction. However, this has not been investigated because of some obstacles to learning minimum metabolites' fundamentals and nonredox properties. This article reviews the electrochemical basis of plants, contrasting it with more conventional techniques and offering both positive and negative perspectives on the topic. Because few studies have been devoted to the concept of merging the domains, we've expanded the scope of this work by including pertinent non-phytochemical reports for better report comparison.

A preliminary evaluation of comparative effectiveness of riluzole in therapeutic regimen for irritable bowel syndrome

Objective: To develop agents that are specifically effective in controlling the key disturbance of visceral hyperalgesia besides abating of associated multiple symptoms, and evaluate comparative effectiveness for IBS symptom relief for standard regimen (antispasmodic and probiotic) and add-on amitriptyine or riluzole regimens following two weeks administration.Methods:groups were studied. First group received standard treatment (mebeverine 200 mg twice daily and probiotic 200 mg twice daily). Second group received add-on amitriptyline 25 mg before bedtime, while the third group got add-on riluzole 50 mg twice daily. Overall gastrointestinal symptom rating scale improving symptoms and hospital anxiety depression scale improving associated psychological morbidity were employed as measures at induction and at two-week follow-up period. Individual symptom scores were also examined to define the outcome profiles.Results:108 patients with visceral hypersensitivity accompanying IBS, divided into three rating scale score, not the other two regimens. Pain relief was seen with both riluzole and amitriptyline regimens significantly superior to standard treatment regimen, but riluzole effect appeared specific and independent anxiolytic effect. Amitriptyline caused relief in diarrhea and did not benefit in constipation point to non-specific remedial role in IBS. Riluzole regimen resulted in significant reduction of overall gastrointestinal symptom Conclusions: Riluzole specifically relieves visceral hypersensitivity and is proved to be superior to current treatments in IBS patients. It appears a lead remedy based on glutamate transporter mechanisms in visceral hypersensititvity.
