Background: Chronic kidney disease (CKD), a condition frequently attributed to uncontrolled diabetes and hypertension, has become an economic and public health burden both globally and locally. The present study was designed to investigate the toxic effects of lead and hypertension (HTN) on chronic renal failure (CRF).
Method: It was a cross-sectional, prospective study conducted in Jinnah Postgraduate Medical Centre, Karachi. A total of 150 adults aged > 40 years were included, 50 were diagnosed patients of hypertension, 50 were diagnosed patients of hypertension with chronic renal failure, and 50 were normal healthy individuals. Levels of lead in blood samples of HTN and CRF patients were estimated besides the levels of HbA1c, glucose, urea, creatinine and antioxidant enzymes (SOD, catalase, NO, Gluthathione peroxidase) by using kit method.
Results: Lead levels were higher in HTN and CRF patients compared to controls. Urea, creatine and creatinine clearance levels were high in patients of HTN with CRF. Glucose and HbAlc levels were higher in HTN, and HTN with CRF patients compared to controls. The activity of antioxidant enzymes was decreased in HTN, and HTN with CRF patients.
Conclusion: Lead exposure with HTN can be a cause of CRF.

Cardiovascular events are positively associated with primary hypertension (HTN), obesity, and low cardiorespiratory fitness (CRF) and negatively with healthy dietary patterns, such as Healthy Diet Indicator (HDI), Mediterranean diet (MD), and the Dietary Approaches to Stop Hypertension (DASH). The aim is to analyze the association between healthy dietary patterns with body composition and CRF. Body composition (bioimpedance) and CRF [peak oxygen uptake (V̇O2peak)] were assessed in 165 participants with HTN and overweight/obesity.

Background: This study aimed to investigate whether higher cardiorespiratory fitness (CRF) can modify the trend of age-related rise in arterial stiffness in individuals with and without hypertension (HTN) or diabetes.
Methods: The study included 4,935 participants who underwent maximal cardiopulmonary exercise testing with respiratory gas analysis in a health screening program. CRF was directly measured using peak oxygen uptake during the cardiopulmonary exercise test, while arterial stiffness was evaluated using brachial-ankle pulse wave velocity (baPWV).

Background: The purpose of the study is to identify the risk factors of mortality early in patients who have history of using of anticoagulants or coagulopathy and sustained a ground level fall (GLF).
Methods: The American College of Surgeons Trauma Quality Improvement Program (ACS-TQIP) dataset of the calendar year 2013 through 2016 was accessed for the study. All elderly patients ≥ 65 years old, who were taking an anticoagulant and suffered from a GLF, were included in the study.

Purpose: There are inverse and independent associations between cardiorespiratory fitness (CRF) and several adverse cardiometabolic outcomes including hypertension (HTN). The prospective relationship between percentage of age-predicted CRF and risk of HTN has not been previously investigated. We aimed to assess the association of percentage of age-predicted CRF with incident HTN in a long-term prospective cohort study.

Article Synopsis
- Arginine vasopressin (AVP) is produced in the paraventricular (PVN) and supraoptic nuclei (SON) of the brain, with increased production in response to conditions like hypovolemia.
- The study focuses on how hypovolemia and hyperosmolality affect AVP dynamics in the magnocellular and parvocellular divisions of the PVN, using genetically modified rats that express AVP-enhanced green fluorescent protein (eGFP).
- Findings show that hypovolemia significantly upregulates AVP and corticotrophin-releasing factor (CRF) synthesis in the pPVN, subsequently activating the hypothalamic-pituitary-adrenal (HPA
