Evidence about the Nigerian health indicators show that the quality of health care in Nigeria is low and inflation of health care prices also persists. Theoretically, by observing the market concentration, inferences can be drawn as to how hospitals conduct themselves, which allows the evaluation of the market performance. Therefore, the effects of market concentration on the health care price and quality were examined. Market concentration was measured by Herfindahl Hirschman Index (HHI) and four hospital concentration ratios (CR). The values of HHI were disaggregated into the less and more concentrated markets. Quality of health care was measured by the staff-nurse-patient ratio. Ordinary Least Square (OLS) was used to estimate the effects of market concentration on price and quality of health care. The price of health care was found to be 13.4% lower in the less concentrated markets than in the more concentrated market. Income significantly and positively influenced health care prices by 17.8%. Also, a low HHI lead to 33.4% increase in Staff-nurse Patient Ratio (SPR) indicating that the quality of health care was higher in less concentrated markets as hospitals increased the treatment intensity via staff-nurse patient ratio. A less concentrated market is linked with higher health care quality and lower health care prices. Therefore, a strategy that will reduce market concentration so as to enhance consumer welfare in terms of price and quality is recommended.

Multiple Sclerosis Center of Excellence West, Veterans Affairs, USA; Rehabilitation Care Service, VA Puget Sound Health Care System, 1660 S Columbian Way, Seattle, Washington, 98108, USA; Department of Rehabilitation Medicine, University of Washington, 325 9th Avenue, Seattle, Washington, 98104, USA. Electronic address:
Background/objective: Identifying research priorities of Veterans, MS researchers, and key stakeholders is critical to advance high-quality, evidence-based, and Veteran-specific MS care.
Methods: We used a modified Delphi approach to identify research priorities for Veterans with MS. Electronic surveys were distributed to Veterans with MS (n = 50,975), MS researchers (n = 191), VA healthcare providers (1,337), and funding agency representatives (n = 6) asking about their 2-3 most important research questions that would benefit Veterans with MS for researchers to answer in the next 5-10 years.

Age Ageing
January 2025
Department of Neurology, Xuanwu Hospital, Capital Medical University, Beijing, China.
Background: A mobile cognition scale for community screening in cognitive impairment with rigorous validation is in paucity. We aimed to develop a digital scale that overcame low education for community screening for mild cognitive impairment (MCI) due to Alzheimer's disease (AD) and AD.
Methods: A mobile cognitive self-assessment scale (CogSAS) was designed through the Delphi process, which is feasible for the older population with low education.
'It is scary to pause treatment': perspectives on HIV cure-related research and analytical treatment interruptions from women diagnosed during acute HIV in Durban, South Africa.

Division of Infectious Diseases and Global Public Health, School of Medicine, University of California San Diego (UCSD), La Jolla, CA, USA.
Background: HIV remains a major challenge in KwaZulu-Natal, South Africa, particularly for young women who face disproportionate risks and barriers to prevention and treatment. Most HIV cure trials, however, occur in high-income countries.
Objective: To examine the perspectives of young women diagnosed with acute HIV in a longitudinal study, focusing on their perceptions on ATI-inclusive HIV cure trials and the barriers and facilitators to participation.
Evaluation of the evidence-based practices for the management of PCOS in the Latin America context: the consensus of the Latin American Association of Gynecological Endocrinology (ALEG).
Gynecol Endocrinol
December 2025
Universidad Finis Terrae, Unidad de Medicina Reprodutiva de Clínicas MEDS y Asociación Latinoamericana de Endocrinología Ginecológica (ALEG), Santiago de Chile, Chile.
Objectives: Polycystic Ovary Syndrome (PCOS) is a complex condition affecting approximately 1 in 10 women of reproductive age. However, limited data are available regarding the specific characteristics and needs of women with PCOS in Latin America. This consensus sought to evaluate the evidence-based practices for the management of PCOS for Latin American populations, consolidate regional insights, identify eventual gaps in implementation and identify key research opportunities.
