(Press-News.org) Miami (April 29, 2025) – Increased perceived stress may cause worsened respiratory symptoms and decreased quality of life in people with chronic obstructive pulmonary disease (COPD), according to a new study. The study is published in the March 2025 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation, a peer-reviewed, open-access journal.
Perceived stress is used to describe how overwhelmed or stressed a person feels based on their personal understanding of the situation. It is a psychosocial factor, along with loneliness, social isolation and emotional support, which have been shown to impact health outcomes in people with chronic diseases.
COPD is an inflammatory lung disease, comprising several conditions, including chronic bronchitis and emphysema, and can be caused by genetics and irritants like smoke or pollution. The disease affects more than 30 million Americans and is the fourth leading cause of death worldwide.
This new study evaluated data from the Comparing Urban and Rural Effects of Poverty on COPD (CURE COPD) study, which examined how obesity, poor diet and indoor air quality impact former smokers with COPD living in low-income, urban areas. The authors examined the association between perceived stress on respiratory health and on platelet activation, oxidative stress and systemic inflammation—biological processes which may contribute to COPD.
“There is increased evidence that psychosocial factors, including perceived stress, are associated with worsened respiratory symptoms for people with COPD. Platelet activation, which may contribute to inflammation, and oxidative stress, which may lead to cell and tissue damage, are also impacted by increased perceived stress,” said Obiageli Lynda Offor, M.D., MPH, a Pulmonary and Critical Care Fellow at Johns Hopkins Medicine in Baltimore, and lead author of the study. “While our study examined a small group of patients, our results demonstrate the need for further research on how perceived stress impacts respiratory health and the importance of addressing psychosocial factors to help improve people’s quality of life.”

COLUMBUS, Ohio – A satisfying intimate relationship may help diminish chemotherapy-related cognitive problems experienced by patients with breast cancer, a new study suggests.
General social support was also protective, but the association was less robust and lasting than a satisfying intimate partnership, which was characterized by fewer declines in both objective measures of cognitive setbacks and patient self-reports of subtle changes such as forgetting grocery list items and being unable to multitask.
The findings suggest that ...
ATLANTA, Georgia, USA, 29 April 2025 -- In a comprehensive Genomic Press research report published today, Emory University investigators have uncovered the complex motivations driving spiritual health practitioners (SHPs) – also known as healthcare chaplains – to pursue careers in the rapidly expanding field of psychedelic-assisted therapy (PAT). The findings shed light on the deeply personal nature of facilitator engagement in psychedelic care and introduce novel training approaches aimed at improving therapeutic outcomes.
As psychedelic treatments gain traction for conditions like treatment-resistant depression, PTSD, and existential distress ...
Cross Country Healthcare (NASDAQ: CCRN), a leader in workforce solutions and tech-enabled staffing, recruitment and advisory services, today released its fourth annual survey, “Beyond the Bedside: The State of Nursing in 2025” report. In partnership with Florida Atlantic University’s Christine E. Lynn College of Nursing, the study paints a sobering picture of a profession at a breaking point – where stress, burnout and chronic short staffing continue to jeopardize the well-being ...
Astronomers have discovered a previously unknown birthplace of some of the universe’s rarest elements: a giant flare unleashed by a supermagnetized star. The astronomers calculated that such flares could be responsible for forging up to 10 percent of our galaxy’s gold, platinum and other heavy elements.
The discovery also resolves a decades-long mystery concerning a bright flash of light and particles spotted by a space telescope in December 2004. The light came from a magnetar — a type of star wrapped in magnetic fields trillions of times as strong as Earth’s — that had unleashed a giant flare. The powerful blast of radiation only lasted a few ...
CHICAGO – From 2010 to 2020, breast cancer deaths among women ages 20-49 declined significantly across all breast cancer subtypes and racial/ethnic groups, with marked declines starting after 2016, according to an analysis of data from the Surveillance, Epidemiology, and End Results (SEER) registry presented at the American Association for Cancer Research (AACR) Annual Meeting 2025, held April 25-30.
Breast cancer incidence rates in women aged 20 to 49 years have been increasing over the past 20 ...
CHICAGO – Cancer survivors who reported feeling cancer-related fatigue or depression reduced their recreational activities nearly twofold, with females more likely than males to report feeling either cancer-related fatigue or depression, according to a retrospective study presented at the American Association for Cancer Research (AACR) Annual Meeting 2025, held April 25-30.
Cancer-related fatigue affects more than 80% of patients who receive chemotherapy or radiation therapy, while depression affects around 25% of cancer patients. Unlike typical fatigue, cancer-related fatigue doesn’t go away with rest and can persist for weeks, months, or even years, explained ...
A research paper by scientists at University of Rome Tor Vergata represented proof of principle of the use of optically-induced dielectrophoresis (ODEP) analysis for the classification of patient-derived endometrial stromal cells, which could be exploited to help clinicians to stratify patients experiencing reproductive failure.
The new research paper, published on Mar. 6 in the journal Cyborg and Bionic Systems, provided the ground for devising a robotic micromanipulation and analysis system for single-cell phenotyping ...
CHICAGO – Patients with advanced solid tumors experienced significantly improved survival outcomes when receiving a tailored therapy based on the detection of the same genomic alteration in both tissue and liquid biopsies compared with both standard-of-care treatment and tailored therapy that was based on either biopsy on its own, according to results from the phase II, multicenter ROME trial presented at the American Association for Cancer Research (AACR) Annual Meeting 2025, held April 25-30.
Genomic profiling is used as part of precision oncology to help identify specific alterations in a tumor that can be targeted with a therapeutic. While tests can be performed ...
A research paper by scientists at Westlake University presented a novel 3D cell culturing and noninvasive characterization technique of neural spheroids, holding a potential application in development of brain organoids.
The new research paper, published on Mar. 5 in the journal Cyborg and Bionic Systems, designed a wire-embedded 3D neural spheroid culture device that not only supports the culture and growth of neural spheroids but also facilitates real-time monitoring of both interior and exterior neural signals without damage.
“In recent years, the field of in vitro neural tissue modeling has undergone substantial advancements, providing researchers with powerful tools ...
A research team led by Dr. Ju-Yul Lee and Dr. Seil Kim from the Energy & Environment Materials Research Division at the Korea Institute of Materials Science (KIMS) has developed the world’s first eco-friendly silver (Ag) plating technology using a phosphorus (P) compound as a key plating component. This breakthrough technology enables silver plating without the use of highly toxic cyanide, by formulating an acidic plating solution based on phosphorus compounds that successfully produces uniform and stable silver thin films.
Silver plating is an essential process for enhancing electrical signal transmission in semiconductors, electronic components, and circuit boards. Conventional ...
