Innovative Dual Combination Cospray-Dried Rock Inhibitor/l-Carnitine Inhalable Dry Powder Aerosols.

This study introduces novel cospray-dried (Co-SD) formulations of simvastatin, a Nrf2 activator ROCK inhibitor, with l-carnitine as molecular mixtures in various molar ratios for targeted pulmonary inhalation aerosol delivery in pulmonary hypertension, optimized for excipient-free dry powder inhalers (DPIs). The two components were spray-dried at various molar ratios by using different starting feed solution concentrations and process parameters. In addition to comprehensive physicochemical characterization, in vitro aerosol dispersion performance as DPIs using two FDA-approved DPI devices with different shear stress properties, in vitro viability as a function of dose on 2D human pulmonary cellular monolayers and on 3D small airway epithelia human primary cultures at the air-liquid interface (ALI), and in vitro transepithelial electrical resistance (TEER) at the ALI were conducted.

Relations Between Optimism-Pessimism and Loneliness in Sexually Minoritized Men: The Moderating Role of Chronicity-Based Discrimination.

Loneliness has reached epidemic proportions, affecting nearly one-in-two adults in the United States and is particularly potent in sexually minoritized men (SMM). Individual differences in optimism and pessimism may exert protective or maladaptive effects for the impact of discrimination on loneliness. This study investigated interrelationships between optimism/pessimism, discrimination, and loneliness within a sample of sexual minoritized men (SMM).

However, the specific types of shoulder injuries and the extent of functional impairment associated with diabetes mellitus remain unclear. This study aimed to assess the association between diabetes and specific shoulder injuries, as well as the degree of functional impairment in affected patients.

Sociocultural and Clinical Determinants of Sexual Dysfunction in Perimenopausal Women with and Without Breast Cancer.

Breast cancer survivorship is a recognized risk factor for sexual dysfunction, with various clinical, sociocultural, and psychological factors potentially interacting differently across populations. This study compared sexual dysfunction, anxiety, and depression between females with breast cancer and those without, aiming to identify associated factors. A total of 362 females participated, including 227 with sexual dysfunction and 135 controls.

Cultural stress and mental health among Venezuelan migrants: cross-national evidence from 2017 to 2024.

Background: Since 2015, ~ 8 million Venezuelans have fled what was once Latin America's most prosperous nation, with many relocating to nearby Colombia and others migrating to the United States (U.S.).

Sex-specific associations of cigarettes and e-cigarettes use with self-reported premature atherosclerotic cardiovascular disease among adults aged 18-54 in the United States.

Background: Premature atherosclerotic cardiovascular disease (ASCVD) is increasing in young adults (<55 years old). While research suggests females who smoke cigarettes have a higher risk of ASCVD than males, studies on the impact of exclusive e-cigarette and dual use on premature ASCVD are limited. This study investigated the association between tobacco use and self-reported premature ASCVD and explored potential sex differences.

Metabolic and bariatric surgery for adolescents with severe obesity: Benefits, risks, and specific considerations.

International and national guidelines recommend metabolic and bariatric surgery (MBS) as a treatment option for adolescents with severe obesity, but few countries offer MBS to adolescents in routine clinical care. This narrative review summarizes existing adolescent MBS guidelines and the available underpinning evidence. Two randomized trials and additional prospective studies have demonstrated efficacy and safety in adolescent MBS, and the health benefits appear to be similar or superior to outcomes in adults.

Cannabis Vaping Among US Adults With Disabilities: Findings From the 2022 Behavioral Risk Factor Surveillance System.

Objectives: Studies have demonstrated that people with disabilities are more likely to use cannabis than people without disabilities. However, less is known about novel forms of use, such as cannabis vaping, in this population. We examined the correlates of cannabis vaping among people with disabilities and the association between cannabis vaping and the frequency of cannabis use in any form.

Work-Related Stress Is Associated With Unfavorable Cardiovascular Health: The Multi-Ethnic Study of Atherosclerosis.

Background: Work-related stress is a psychosocial risk factor linked to a higher risk of cardiovascular disease. However, the association between work-related stress and cardiovascular health (CVH) is not well established. We estimated the association between work-related stress and CVH in a multiethnic sample of adults free of cardiovascular disease at baseline.

Efficacy of neutral electrolyzed water vs. common topical antiseptics in the healing of full‑thickness burn: Preclinical trial in a mouse model.

Burn injuries impose challenges such as infection risk, pain management, fluid loss, electrolyte imbalance and psychological and emotional impact, on healthcare professionals, requiring effective treatments to enhance wound healing. The present study evaluated the efficacy superoxidized electrolyzed solution (SES), with low (SES-low) or high (SES-high) concentrations of active species, alone or in combination with a formulation in gel (G), in comparison with commonly prescribed treatments for burn injury, including nitrofurazone (NF) and silver sulfadiazine (S); normal saline was used as placebo (PI). A scald burn model was established in BALB/c mice.

COVID-19 related cognitive, structural and functional brain changes among Italian adolescents and young adults: a multimodal longitudinal case-control study.

Coronavirus disease 2019 (COVID-19) has been associated with brain functional, structural, and cognitive changes that persist months after infection. Most studies of the neurologic outcomes related to COVID-19 focus on severe infection and aging populations. Here, we investigated the neural activities underlying COVID-19 related outcomes in a case-control study of mildly infected youth enrolled in a longitudinal study in Lombardy, Italy, a global hotspot of COVID-19.

Preferential Initiation of Long-Acting Injectable Versus Oral HIV Pre-Exposure Prophylaxis Among Women Who Inject Drugs.

Fifty-five of 62 women who inject drugs (WWID) selected long-acting cabotegravir (CAB-LA) over oral PrEP, and 51/55 received a first injection. More recent injection drug use and number of sexual partners were associated with selecting CAB-LA (P < .05).

The mitochondrial redistribution of ENOS is regulated by AKT1 and dimer status.

Previously, we have shown that endothelial nitric-oxide synthase (eNOS) dimer levels directly correlate with the interaction of eNOS with hsp90 (heat shock protein 90). Further, the disruption of eNOS dimerization correlates with its redistribution to the mitochondria. However, the causal link between these events has yet to be investigated and was the focus of this study.

Association of Methylenetetrahydrofolate Reductase () Polymorphism with Osteosarcoma in a Mexican Population.

The methylenetetrahydrofolate reductase () gene 677C➔T polymorphism is capable of altering folate metabolism and can modify certain neoplasia risk. Reports have suggested that folate can have an influence on bone development and so it is of interest to know if the 677C➔T polymorphism is associated with the malignant transformation process of this tissue. The polymorphism was determined in 55 patients with osteosarcoma and in 180 healthy individuals.

The Relationship Between Loneliness, Social Isolation, and Inflammatory Bowel Disease: A Narrative Review.
