Authors: Nakayama Ayako , Hoshino Junko , Hotta Masashi , Hashimoto Mayuri , Furukawa Naomi 
Published: January 2025

Background: With an aging global population, establishing integrated systems for long-term care is challenging in several countries. Adequate and quality service for older adults in nursing homes can improve their quality of life. The career self-reliance of nurses working in nursing homes may affect the quality of life of older adults; this suggests a need for educational support for career self-reliance behavior.
Objective: Our study aimed to identify characteristics associated with the career self-reliance behaviors of nurses working in nursing homes.
Methods: Data were collected from nurses working in 789 nursing homes in Japan using questionnaires in 2018. The questionnaire consisted of the Scale of Career Self-Reliance Attitude, Career Self-Reliance Behavior to measure the degree of nurses’ career self-reliance, questions about personal attributes, work environment, and work commitment; and the Clinical Nursing Competence Self-Assessment Scale. A multiple regression analysis was conducted using career self-reliance as the dependent variable and characteristics as the independent variables.
Results: Consequently, a total of 336 questionnaires were collected, of which 289 without missing data were analyzed. Of the 289 participants, 79 (27.3%) had certifications or licenses other than those for nursing or had completed graduate school. As a result of multiple regression analysis, a higher frequency of nursing practice (β = 0.38, p <0.001) was associated with career self-reliance attitudes. Having certifications or licenses other than those for nursing or completing graduate school (β = 0.11, p = 0.03), job satisfaction as a nurse (β = 0.12, p = 0.03), higher frequency of nursing practice (β = 0.28, p <0.001), and a higher degree of career self-reliance attitude (β = 0.45, p <0.001) were associated with career self-reliance behavior. Relationships with supervisors or colleagues were not associated with career self-reliance.
Conclusion: It is important for nurses working in nursing homes to enrich their nursing practice, continue learning, and be satisfied with their jobs to improve their career self-reliance. Nurses and administrators working in nursing homes should make efforts to obtain these characteristics for nurses’ career self-reliance behaviors. Particularly, maintaining nursing practice frequency is essential for improving the quality of life of older adults through nurses’ career self-reliance.

Published: January 2025

Background: The global prevalence of older adults with diabetes has increased, and family caregivers in Indonesia play a critical role in managing diabetes and providing personal care. However, caregiving can be complex and challenging, often negatively affecting caregivers' quality of life (QoL).
Objective: This study aimed to develop and test a hypothesized causal model of QoL among Indonesian family caregivers who care for dependent older persons with type 2 diabetes mellitus (T2DM) in 2024.
Methods: A cross-sectional, correlational study was conducted with 270 family caregivers recruited from five Community Health Centers. Data were collected using various scales: the Center for Epidemiologic Studies Depression Scale, the Zarit Burden Interview, the Duke University Religion Index, the Perceived Knowledge on T2DM Care Scale, the Family-Carer Diabetes Management Self-Efficacy Scale, the Multidimensional Scale of Perceived Social Support, and the Quality-of-Life Index. Descriptive statistics and Partial Least Squares Structural Equation Modeling (PLS-SEM) were used for analysis.
Results: The final model explained 89.1% of the variance in the quality of life (QoL) of family caregivers (R² = 0.893, Adjusted R² = 0.891), with 66% predictive relevance. Depression symptoms had the strongest negative direct effect on QoL, followed by caregiver burden. Self-efficacy and perceived knowledge had positive direct effects, while social support showed no significant direct effect. Indirect effects revealed that social support and self-efficacy positively influenced QoL through depression symptoms. The total effect (TE) analysis confirmed that depression symptoms had the strongest negative effect on QoL (TE = -0.744, p <0.001), while social support (TE = 0.443, p <0.001) and self-efficacy (TE = 0.413, p <0.001) had positive effects.
Conclusion: Reducing depression symptoms and caregiver burden, strengthening social support, and promoting self-efficacy could significantly improve the QoL of family caregivers who care for older persons with T2DM. Nursing practice should address caregivers' physical and emotional needs, provide education, foster social support, and support caregiver mental health.

Published: January 2025

BackgroundMaternal thyroid hormones play a vital role in fetal development, and imbalances can lead to adverse outcomes. Iron deficiency may impair thyroid function due to iron’s essential role in iodine oxidation during thyroid hormone synthesis. This review examines the relationship between various indicators of maternal iron status and thyroid function during pregnancy.MethodsWe conducted a systematic search in MEDLINE/PubMed, Web of Science, Embase, Scopus, and the Cochrane Library for studies published up to 2023. Meta-analyses determined pooled thyroid hormone levels in patients with and without iron deficiency, using serum ferritin (cut-off = 30 µg/L) and hemoglobin (cut-off = 11 g/dL). Meta-regression analyses examined linear relationships between iron status indicators and thyroid hormones.ResultsForty-seven studies involving 53,152 pregnant women were included. Meta-analysis showed no significant difference in thyroid-stimulating hormone, free T4, or total T4 when considering serum ferritin levels in iron-deficient versus iron-sufficient individuals. However, regarding hemoglobin levels, iron deficiency was associated with higher thyroid-stimulating hormone (2.31 mIU/L vs. 1.75 mIU/L) and lower free T4 (10.7 pmol/L vs. 13.3 pmol/L), but not total T4. Meta-regression revealed no significant associations between serum ferritin and thyroid hormones. Conversely, maternal hemoglobin levels were inversely associated with thyroid-stimulating hormone (P-value = 0.009) and directly associated with free T4 (P-value &lt; 0.001), with no significant link to total T4.ConclusionsMaternal hemoglobin levels are more strongly correlated with thyroid function than serum ferritin levels. This suggests that monitoring hemoglobin could enhance the early detection and management of thyroid dysfunction during pregnancy.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO, identifier CRD4202451820.

Authors: Phoya Frank , Butters Claire , Spracklen Timothy F. , Kassa Hanna L. , van der Ross Hamza , Scott Chris , Webb Kate 
Published: January 2025

BackgroundMultisystem inflammatory syndrome in children (MIS-C) is a disease that occurs after exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Its short-term effects have been documented but little data exist on the longer term effects of MIS-C on the health and quality of life (QOL) of patients. The objective of this study was to assess the long-term effects of MIS-C on the QOL of children.MethodsThis study was a descriptive prospective study. We included 24 participants with previous MIS-C and 20 children with juvenile idiopathic arthritis (JIA) as a positive comparator group. All children were examined and completed a paediatric quality of life (PedsQL) generic inventory score. This score was used to evaluate the School Functioning, Social, Emotional, and Physical QOL domains.ResultsAll participants with previous MIS-C made a full recovery, with no medical complaints, and normal physical examinations after a median of 705 days post acute diagnosis. The PedsQL inventory revealed that 16.7% of the children with previous MIS-C showed a deficit in the physical domain compared to 60% of the children with JIA (p &lt; 0.001). 12.5% of the children with previous MIS-C had a deficit in their psychosocial domain which included emotional, social, and educational scores, compared to 40% of the children with JIA (p = 0.035).ConclusionsIn a cohort of 24 South African children with previous MIS-C, no medical complications were reported. A small proportion felt a prolonged effect on their QOL even after making a full recovery, although this was not as severe as children with JIA, a known chronic disease that affects QOL. This highlights the need to continue to follow up these patients and offer more comprehensive long-term care.

Published: January 2025

Introdução. O delirium é um transtorno neurocognitivo caracterizado por alterações da atenção ou consciência, o qual é frequentemente observado em pessoas idosas que sofreram fratura no quadril. Objetivo. Descrever as intervenções médicas voltadas ao diagnóstico e manejo clínico do delirium em pessoas idosas que apresentam fratura de quadril. Método. Trata-se de uma revisão integrativa, realizada nos indexadores LILACS, MEDLINE, Web of Science, Scopus e PubMed, utilizando os termos “Delirium”, “Elderly” e “Hip Fractures”, incluindo estudos publicados entre 2019 e 2024, em português e inglês. Resultados. Foram selecionados 43 artigos, nos quais a incidência média de delirium foi de 24,89%, estando associado principalmente à idade, hipoalbuminemia, histórico de delirium e transfusão sanguínea. Foi identificado também um maior risco de mortalidade e reinternação hospitalar, sendo a maior eficácia de tratamento associada à abordagem multidisciplinar e à utilização de intervenções farmacológicas e não-farmacológicas. Embora os fatores etiológicos e métodos diagnósticos do delirium sejam amplamente difundidos, há altas taxas de subdiagnóstico nas UTI, devido a um rastreio prejudicado, indicando lacunas no conhecimento dos profissionais de saúde. Conclusão. É essencial a consolidação da abordagem diagnóstica e terapêutica para o manejo do delirium, sendo necessárias novas pesquisas para a discussão e aprofundamento dessa temática, haja vista que muitas pessoas idosas internadas em UTI apresentam esse transtorno.
