Article Abstract
Background/objectives: Myelodysplastic syndromes (MDS) are clonal hematopoietic disorders characterized by ineffective hematopoiesis and a risk of progression to acute myeloid leukemia (AML). Cognitive impairments, including deficits in memory, attention, and executive function, are frequently reported in MDS patients. These impairments are linked to systemic inflammation, neurotoxic treatment effects, and the psychological burden of chronic disease. This review synthesizes existing evidence on cognitive dysfunction in MDS, highlighting knowledge gaps and opportunities for future research.
Methods: A scoping review was conducted following PRISMA-ScR guidelines. MEDLINE and Scopus databases were searched for studies examining cognition in MDS patients, using terms like "myelodysplastic syndromes" and "cognition." Inclusion criteria were original, English-language studies reporting cognitive outcomes in MDS. Reviews, animal studies, and abstracts were excluded. Data on study design, patient characteristics, cognitive tests, and outcomes were extracted and descriptively analyzed.
Results: The review included 25 studies involving 2390 patients with hematologic malignancies, 493 of whom had MDS. Key findings identified cognitive deficits primarily in attention, executive function, and memory. Systemic inflammation and treatment-related neurotoxicity were significant contributors, with older age compounding these effects. Longitudinal studies demonstrated persistent cognitive challenges post-treatment, though the severity varied by patient demographics and therapeutic regimens.
Conclusions: Cognitive impairments in MDS are multifactorial and significantly impact patients' quality of life. Current research highlights the need for routine cognitive assessments and targeted interventions. Future studies should focus on longitudinal designs to explore specific cognitive domains and develop therapeutic strategies to mitigate cognitive decline.

Background: Quality of life is an important goal of care for people living with amyotrophic lateral sclerosis (ALS) and their carers. The ALS Specific Quality of Life instrument Short Form (ALSSQOL-SF) has been translated and validated in various cultural contexts, however its utility in the Malaysian cultural context has not yet been evaluated.
Methods: The quality of life of 21 patients with ALS was evaluated using the ALSSOL-SF in either the English version or translated to the Malay language.
Wellness Misinformation on Social Media: A Systematic Review Using Social Cognitive Theory.
Health Commun

Department of Graduate Studies, Wenzhou Medical University.
This systematic review examines how wellness misinformation spreads on social media and identifies counter-strategies through the lens of social cognitive theory (SCT). Analyzing 39 studies from 2019-2024, it highlights key SCT themes - observational learning, self-efficacy, and self-regulation - as central to user behavior. Influencers and algorithm-driven content amplify unverified health claims, especially on platforms like TikTok and Twitter.

Aims: Loneliness is a common public health concern, particularly among mid- to later-life adults. However, its impact on early mortality (deaths occurring before reaching the oldest old age of 85 years) remains underexplored. This study examined the predictive role of loneliness on early mortality across different age groups using data from the Health and Retirement Study (HRS).
