lung and sleep center :: Article Creator Walking May Improve Sleep With Lung CancerFox News man goes to a great trip (iStock) Lung cancer patients could improve their sleep and quality of life by walking several times a week, a study from Taiwan suggests. Those who participated in a 12-week home-based walking program had better sleep quality at both three and six months after the program. The results reinforce similar findings in breast and colorectal cancer patients, researchers say. "Walking is safe, feasible and effective for patients. Just walk!" said senior author Chia-Chin Lin, a nursing professor at Taipei Medical University. Lin and colleagues have published several studies in recent years about links between physical activity, sleep and quality of life in lung cancer patients. Lung cancer patients often experience sleep problems during and after treatment, Lin said, which can affect quality of life and canc...

intracranial pressure symptoms :: Article Creator GLP-1 Receptor Agonists Promising In Managing Idiopathic Intracranial Hypertension: JAMA Study USA: Researchers have found in a new study that patients with idiopathic intracranial hypertension (IIH) treated with glucagon-like peptide 1 receptor agonists (GLP-1 RAs) experienced fewer symptoms, required less medication, and underwent fewer procedures over one year compared to those on conventional therapies. Published in JAMA Neurology, the study highlights the potential of GLP-1 RA therapy as an alternative approach to managing this challenging neurological condition. IIH, a disorder marked by increased pressure around the brain without an apparent cause, typically affects overweight women of reproductive age. The standard treatments—such as acetazolamide, topiramate, or lifestyle modifications—often have limited success and may not fully address the condition's complex presentation. ...

lungs cardiovascular system :: Article Creator Cardiovascular System: Function, Organs, Conditions, And More The cardiovascular system consists of the heart, blood vessels, and blood. Its primary function is to transport nutrients and oxygen-rich blood to all parts of the body and to carry deoxygenated blood back to the lungs. Abnormalities or injuries to any part of the cardiovascular system can result in serious health complications. Common conditions that can affect the cardiovascular system include coronary artery disease, heart attack, high blood pressure, and stroke. This article explores the cardiovascular system, including its components and their functions. It also outlines some common cardiovascular system conditions. The heart: The heart is a muscular pump that forces blood around the body. A closed system of blood vessels: Blood vessels include: Arteries: The arteries carry blood away from the heart. Ve...

congestive heart failure is :: Article Creator My Parents Both Died By Suicide — On The Same Day. I Haven't Been The Same Since. The author's parents in 1947. In the middle of a plate of enchiladas and salad, the phone rings. I sigh — it's been days since I've had the time or appetite to enjoy a meal. My husband, Tom, is busy at the kitchen counter, so I reach for the phone, and my brother says, "They're both gone." It's 2 p.M. on Dec. 18, 1994, and with those three words, I am orphaned. After several years of suffering physical and mental anguish, my mother could take no more, and my father, who people later said couldn't bear the thought of life without his bride of 46 years, went along for the final ride, ending both their lives in their garage. On that day, as Tom and I made the 90-minute drive from our home in Massachusetts to the small farm in Connecticut where I was brought up, I looked to the s...

high altitude and pulmonary hypertension :: Article Creator Pulmonary Hypertension Linked With Poor Outcomes In Kidney Transplant Recipients Pre-existing pulmonary hypertension in kidney transplant recipients (PHTN) is associated with greater risks of early mortality and allograft failure, a recent study finds. Isabel G. Scalia, MD, of Mayo Clinic, Phoenix, Arizona, and colleagues conducted a retrospective study and analysis of medical records from 5322 consecutive adult kidney transplant recipients at 3 US tertiary transplant centers from 2011 to 2021. The mean patient age was 55.2 years, and 58.8% were male. PHTN, defined as right ventricular systolic pressure greater than or equal to 35 mm Hg on transthoracic echocardiography, was present in 1726 patients (32.4%). The PHTN group was more commonly older males with several preexisting comorbidities and had longer dialysis history. Patients with vs without PHTN had a significantly lower 5-year...
