Negative exchanges in social relationships have traditionally been studied as having negative consequences. This study explored whether they might have positive effects for relationship closeness. The sample included 351 adults, aged between 18 and 91 years, residing in Hong Kong, China. Closeness of social partners to the participants was measured by the Social Convoy Questionnaire, and the levels of negative exchanges and social support from each social partner were assessed. Multilevel analyses revealed that more negative exchanges were associated with a more positive change in closeness over a 2-year period, even after statistically controlling for social support and sociostructural characteristics of the participant and the social partner. Findings extended our knowledge on the positive effects of negative exchanges and their moderating conditions.

Introduction: Social media plays a significant role in fostering communities around health and wellness. The hashtag #PCOSweightloss has become a pivotal forum on the platform X, where individuals exchange experiences, share information, and motivate each other concerning weight loss strategies connected with Polycystic Ovary Syndrome (PCOS).
Objective: This study aims to analyze the trends of #PCOSweightloss on X to gain insights into the social media metrics, including overall hashtag reach, key themes, and potential influence on management practices of PCOS.

Nanoparticles (approximately 100 nm in diameter) composed of lipid layers containing drugs or biologically active substances are attracting increasing attention in various fields, including medicine, as well as for signal transduction between cells. However, the separation of such nanoparticles conventional HPLC is challenging, often resulting in the clogging and collapse of nanoparticles, as well as a low separation efficiency. Thus far, no HPLC column capable of efficiently separating two types of 100 nm-sized nanoparticles in a short time has been reported.

Heat stress negatively affects pig production by disrupting the immune homeostasis of Sertoli cells (SCs), which compromises sperm quality, culminating in male infertility. Herein, we aimed to study the mechanism by which the NLRP3 inflammasome is activated by heat stress through N6-methyladenosine (mA) modification regulation in SCs. Initially, it was found that heat stress (44°C, 30 min) markedly activated ERK1/2 signaling, which subsequently promoted NLRP3 inflammasome activation and inflammatory cytokine release from SCs.

Objective: To describe the prevalence of and trends in practices that interfere with the exchange of patient health information (potential information blocking) 2 years after implementation of information-blocking regulations.
Materials And Methods: Drawing from the American Hospital Association Information Technology (IT) Supplement and a national survey of health information organizations (HIOs), we described rates and methods of potential information blocking from these organizations' perspectives in 2023 and compared them to prior years.
Results: Twenty-seven percent of hospitals sometimes or often observed potential information blocking by any actor in 2023, down from 42% in 2021 and 33% in 2022.

The rising incidence of noncommunicable diseases, combined with the costs of mitigating climate change, sovereign debt and regional conflicts, is undermining global health security and threatening progress towards achieving the sustainable development goals of the United Nations. The negative impact of these polycrises is disproportionately borne by low- and middle-income countries, which have the highest disease burden and lowest health-care spending. Health digitalization is emerging as a promising countermeasure, accelerated by artificial intelligence (AI) software and quantum computing hardware.
