RESUMEN
OBJECTIVE: Alterations in the suprachiasmatic nucleus due to underlying pathologies disrupt the circadian rhythms in people living with dementia (PLWD). Circadian rhythms significantly impact sleep, emotional, and cognitive functions, with its synchronization depending on light exposure. We performed a meta-analysis to evaluate the effects of light therapy on sleep, depression, neuropsychiatric behaviors, and cognition among PLWD. METHODS: A systematic search was conducted in Cochrane, ClinicalTrials.gov, Embase, EBSCOhost, Ovid-MEDLINE, PubMed, Scopus, Web of Science, and CINAHL databases. The pooled effect size was calculated using the Hedges' g with random-effects model adopted in comprehensive meta-analysis software. The Cochrane risk of bias (RoB 2.0) tool evaluated the quality of studies, while Cochrane's Q and I² tests assessed heterogeneity. RESULTS: A total of 24 studies with 1,074 participants were included. Light therapy demonstrated small-to-medium effects on improving sleep parameters: total sleep time (Hedges' g = 0.19), wake after sleep onset (Hedges' g = 0.24), sleep efficiency (Hedges' g = 0.31), sleep latency (Hedges' g = 0.35), circadian rhythm (acrophase: Hedges' g = 0.36; amplitude: Hedges' g = 0.43), number of night awakenings (Hedges' g = 0.37), sleep disturbance (Hedges'g = 0.45), and sleep quality (Hedges' g = 0.60). Light therapy showed small-to-medium effect on reducing depression (Hedges' g = -0.46) with medium-to-large effect on cyclical function (Hedges' g = -0.68) and mood-related signs and symptoms (Hedges' g = -0.84) subscales. Light therapy also demonstrated small effect on reducing neuropsychiatric behaviors (Hedges' g = -0.34) with medium-to-large effect on agitation (Hedges' g = -0.65), affective symptom (Hedges' g = -0.70), psychosis (Hedges' g = -0.72), and melancholic behavior (Hedges' g = -0.91) subscales. Additionally, light therapy also improved cognition (Hedges' g = 0.39). CONCLUSION: Light therapy could be used as a supportive therapy to improve sleep, depression, cognition, and neuropsychiatric behaviors among PLWD.

BACKGROUND: Hemodialysis holds the highest incidence and prevalence rate in Taiwan globally. However, the implementation of advance care planning (ACP), advance directives (AD), and patient self-determination acts (PSDA) remains limited. Our objective was to examine the current status of ACP, AD and PSDA and potential opportunities for enhancement. METHODS: We developed a novel questionnaire to assess individuals' knowledge, attitudes, and intentions regarding ACP, AD, and PSDA. We also collected baseline characteristics and additional inquiries for correlation analysis to identify potential factors. Student's t-test and Analysis of Variance were employed to assess significance. RESULTS: Initially, a cohort of 241 patients was initially considered for inclusion in this study. Subsequently, 135 patients agreed to participate in the questionnaire study, resulting in 129 valid questionnaires. Among these respondents, 76 were male (59.9%), and 53 were female (41.1%). Only 13.2% had signed AD. A significant portion (85.3%) indicated that they had not discussed their dialysis prognosis with healthcare providers. Additionally, a mere 14% engaged in conversations about life-threatening decisions. Ninety percent believed that healthcare providers had not furnished information about ACP, and only 30% had discussed such choices with their families. The findings revealed that the average standardized score for ACP and AD goals was 84.97, while the attitude towards PSDA received a standardized score of 69.94. The intention score stood at 69.52 in standardized terms. Potential candidates for ACP initiation included individuals aged 50 to 64, possessing at least a college education, being unmarried, and having no history of diabetes. CONCLUSION: Patients undergoing hemodialysis exhibited a significant knowledge gap concerning ACP, AD, and the PSDA. Notably, a substantial number of dialytic patients had not received adequate information on these subjects. Nevertheless, they displayed a positive attitude, and a considerable proportion expressed a willingness to sign AD. It is imperative for nephrologists to take an active role in initiating ACP discussions with patients from the very beginning.

This study proposed a robot-assisted digital storytelling approach to reduce hospitalized children's anxiety about intravenous injections and to improve their therapeutic communication and therapeutic engagement. In order to verify the effectiveness of the robot-assisted digital storytelling approach, a randomized controlled study was implemented. A total of 47 children from a regional hospital were randomly assigned to an experimental group (n = 21) and a control group (n = 26). The experimental group adopted the robot-assisted digital storytelling approach in health education for intravenous injections, while the control group received video-based health education. The study results indicated that the proposed robot-assisted digital storytelling approach not only reduced the children's anxiety, but also had positive effects on children's communication about intravenous injections, emotions during hospitalization, and therapeutic engagement. As a consequence, it is suggested that educators and researchers consider adopting robot-assisted digital storytelling to facilitate nursing clinical health education for children.
RESUMEN
AIM: To explore the effectiveness of a digital learning management system in enhancing intensive care unit nurses' critical care knowledge and critical thinking tendency. BACKGROUND: Learning intensive care unit knowledge and skills is essential for the continuing education of nurses, and impacts patient health outcomes. Enhancing intensive care unit nurses' critical care abilities is a medical care quality concern in clinical practice. METHODS: A cross-sectional study was conducted with 212 participants to investigate the effects of a digital learning system on care quality. RESULTS: After the implementation of the digital learning system, intensive care unit nurses' critical care knowledge and critical thinking skills increased significantly. High-level nurses had higher critical thinking scores. All participants associated critical care knowledge with improved quality of care. CONCLUSION: The digital learning management system enhanced intensive care unit nurses' critical care knowledge. Optimizing nursing care safety and quality requires that nursing staff to be at an adequate level, which improves their critical care ability. IMPLICATIONS FOR NURSING MANAGEMENT: A well-designed digital learning management system with structured classes may allow intensive care unit nurses to learn effectively and can be used for continuing education. These results are of interest to nursing management staff who want to invest in the continued professional development of intensive care unit nurses to improve critical care knowledge, critical thinking skills, care quality, and health care value.

OBJECTIVE: To investigate the academic use of artificial intelligence (AI) in nursing. BACKGROUND: A bibliometric analysis combined with the VOSviewer software quantification method has been utilized for a literature analysis. In recent years, this approach has attracted the interest of scholars in various research fields. Thus far, there is no publication using bibliometric analysis combined with the VOSviewer software to analyse the applications of AI in nursing. METHOD: A bibliometric analysis methodology was used to search for relevant articles published between 1984 and March 2022. Six databases, Embase, Scopus, PubMed, CINAHL, WoS and MEDLINE, were included to identify relevant studies, and data such as the year of publication, journals, country, institutional source, field and keywords were analysed. RESULTS: Most relevant articles were published from institutions in the United States. The League of European Research Universities has published most research studies that use AI and nursing. Scholars have mainly focused on nursing, medical informatics, computer science AI, healthcare sciences services and physics particles fields. Commonly used keywords were machine learning, care, AI, natural language processing, prediction and nurse. CONCLUSION: Research articles were mainly published in Nurse Education Today. Research topics such as AI-assisted medical recording and medical decision making were also identified. According to this study, AI in nursing has the potential to attract more attention from researchers and nursing managers. Additional high-quality research beyond the scope of medical education, as well as on cross-domain collaboration, is warranted to explore the acceptability and effective implementation of AI technologies. IMPLICATIONS FOR NURSING MANAGEMENT: This study provides scholars and nursing managers with structured information regarding the use of AI in nursing based on scientific and technological developments across different fields and institutions. The application of AI can improve nursing management, nursing quality, safety management and team communication, as well as encourage future international collaboration.

AIMS: This study aimed to identify high-impact papers on global nursing to determine and analyse the publication of articles on core competencies in nursing-related journals and the research trends in the era of globalization. BACKGROUND: Bibliometrics has been shown to be an effective method for analysing publications. Through bibliometrics, nursing managers and researchers can understand the trends of high-impact international nursing core competencies research, identify mainstream research directions and obtain relevant knowledge and information, thereby facilitating the translation of research outcomes into nursing management practice. EVALUATION: The study adopted bibliometric analysis and the VOSviewer software to explore dynamic publication trends and analyse the current situation of nursing research from a comprehensive development perspective, which was realized by searching for nursing core competencies papers in the Web of Science (WoS) database, calculating citations and determining the trends of the most influential papers. KEY ISSUES: Nursing core competencies research grew rapidly between 1997 and 2022. Countries with the most core competencies publications were the United States, England, Australia and Canada. The Journal of Nursing Management has attracted substantial attention from researchers worldwide. Education, Management and Nurses were the most frequently used keywords in the study. A total of 534 papers were retrieved from the WoS database with the main research fields, including nursing, business economics, public environmental occupational health and health care science services. CONCLUSION: Equipping nursing graduates with core competencies has always been an important goal of global medical and nursing education. This study analysed papers across 35 years, most of which were published in the Journal of Nursing Management. In addition, the study identified some of the main research topics of nursing management, such as the integration of education with nursing management and the cultivation of nurses' core competencies. The study also provides a fresh review of highly cited articles. The results of the study show that high-quality articles play the role of improving both the quality and the quantity of related research. By analysing the trends of the research on core competencies, this study lays a bibliometric foundation for researchers regarding international journals, hot topics and relevant fields. In addition, the highly cited articles reveal new perspectives for the nursing field, providing inspiration for nursing management and education researchers. IMPLICATIONS FOR NURSING MANAGEMENT: This study provides scholars and managers with an overview of the current situation of nursing management research and the development of benchmark journals. The study provides researchers not only with a better understanding of various international journals, allowing them to transition out of traditional thinking in the era of science and technology, but also with innovative thinking by combining research with nursing management. The results of this study invite nursing managers to study relevant topics of core competencies and integrate information technology to education, management and nurses, thereby contributing to nursing management and educational research.

Students who learn evidence-based nursing can assist the healthcare team to make proper medical decisions and provide patients with valuable advice, thus optimizing the quality of patient care in specific situations. In clinical work, nursing staff members participate in decision making by searching for relevant empirical nursing literature, a basic ability required to enter clinical practice. In traditional instruction, nursing students are taught the Problem, Intervention, Comparison, and Outcome method to learn to use library resources and gather empirical nursing knowledge for decision making. However, it is a challenge for most students to have sufficient practice to make decisions correctly and to have opportunities to perceive medical cases from diverse perspectives. Therefore, we propose a peer assessment-based Problem, Intervention, Comparison, and Outcome approach to help nursing students locate correct evidence and make appropriate decisions about patient care. We performed an experiment with our approach in a nursing university training program. The experimental results reveal that the subjects learning with the proposed approach show better evidence-based nursing knowledge, learning attitude, and critical thinking ability than those learning with the traditional approach.

OBJECTIVE: Endocrine therapy is often considered as a treatment for hormone-responsive gynecologic malignancies. In breast cancer, activating mutations in the estrogen receptor (mutESR1) contribute to therapeutic resistance to endocrine therapy, especially aromatase inhibitors (AIs). The purpose of this study was to evaluate the frequency and clinical relevance of ESR1 genomic alterations in gynecologic malignancies. METHODS: DNA from FFPE tumor tissue obtained during routine clinical care for 9645 gynecologic malignancies (ovary, fallopian tube, uterus, cervix, vagina, vulvar, and placenta) was analyzed for all classes of genomic alterations (base substitutions (muts), insertions, deletions, rearrangements, and amplifications) in ESR1 by hybrid capture next generation sequencing. A subset of alterations was characterized in laboratory-based transcription assays for response to endocrine therapies. RESULTS: A total of 295 ESR1 genomic alterations were identified in 285 (3.0%) cases. mutESR1 were present in 86 (0.9%) cases and were more common in uterine compared to other cancers (2.0% vs <1%, respectively pâ¯<â¯0.001). mutESR1 were enriched in carcinomas with endometrioid versus serous histology (4.4% vs 0.2% respectively, pâ¯<â¯0.0001 in uterine and 3.5% vs 0.3% respectively, pâ¯=â¯0.0004 in ovarian carcinomas). In three of four patients with serial sampling, mutESR1 emerged under the selective pressure of AI therapy. Despite decreased potency of estrogen receptor (ER) antagonists in transcriptional assays, clinical benefit was observed following treatment with selective ER-targeted therapy, in one case lasting >48â¯months. CONCLUSIONS: While the prevalence of ESR1 mutations in gynecologic malignancies is low, there are significant clinical implications useful in guiding therapeutic approaches for these cancers.

BACKGROUND: In childhood cancer survivors, low bone mineral density (BMD) is a bone-related consequence. Efficacy of denosumab, an effective therapy for adult patients with osteoporosis, remains unclear in children. This study aimed to investigate denosumab therapy efficacy for low BMD in childhood cancer survivors. PROCEDURE: Between January 2014 and January 2018, we monitored lumbar BMD of children with cancer using dual-energy X-ray absorptiometry after completing chemotherapy with a 6-month interval. For patients with low BMD, defined as height-adjusted Z-scores of BMD < -1.5 in this study, calcium carbonate and vitamin D supplements were initially administered. When low BMD continued for at least 6 months, denosumab therapy was introduced. Calcium and vitamin D supplementation were continued in patients on denosumab. We investigated BMD change and adverse effects during denosumab therapy. RESULTS: During the study period, 20 patients received denosumab treatment. Mean height-adjusted Z-score of BMD before denosumab treatment was -2.68 but increased to -2, -1.96, and -1.33 at 0.5, 1, and 1.5 years after denosumab treatment, respectively (P = .012). In addition, hypocalcemia occurred in 40% (8/20) of patients; three patients had hypocalcemic symptoms with numbness in all four limbs. All hypocalcemic patients, except one patient who died due to relapsed leukemia, recovered well after continuous calcium supplementation. CONCLUSIONS: Denosumab is an effective treatment for low BMD in childhood cancer survivors. However, the complication of hypocalcemia might develop posttreatment.

BACKGROUND: Whereas the androgen receptor (AR) signaling axis remains a therapeutic target in castration-resistant prostate cancer (CRPC), the emergence of AR mutations and splice variants as mechanisms underlying resistance to contemporary inhibitors of this pathway highlights the need for new therapeutic approaches to target this disease. Of significance in this regard is the considerable preclinical data, indicating that histone deacetylase (HDAC) inhibitors may have utility in the treatment of CRPC. However, the results of clinical studies using HDAC inhibitors (directed against HDAC1, 2, 3, and 8) in CRPC are equivocal, a result that some have attributed to their ability to induce an epithelial to mesenchymal transition (EMT) and neuroendocrine differentiation. We posited that it might be possible to uncouple the beneficial effects of HDAC inhibitors on AR signaling from their undesired activities by targeting specific HDACs as opposed to using the pan-inhibitor strategy that has been employed to date. METHODS: The relative abilities of pan- and selective-Class I HDAC inhibitors to attenuate AR-mediated target gene expression and proliferation were assessed in several prostate cancer cell lines. Small interfering RNA (siRNA)-mediated knockdown approaches were used to confirm the importance of of HDAC 1, 2, and 3 expression in these processes. Further, the ability of each HDAC inhibitor to induce the expression of EMT markers (RNA and protein) and EMT-like phenotype(s) (migration) were also assessed. The anti-tumor efficacy of a HDAC3-selective inhibitor, RGFP966, was compared to the pan-HDAC inhibitor Suberoylanilide Hydroxamic Acid (SAHA) in the 22Rv1 xenograft model. RESULTS: Using genetic and pharmacological approaches we demonstrated that a useful inhibition of AR transcriptional activity, absent the induction of EMT, could be achieved by specifically inhibiting HDAC3. Significantly, we also determined that HDAC3 inhibitors blocked the activity of the constitutively active AR V7-splice variant and inhibited the growth of xenograft tumors expressing this protein. CONCLUSIONS: Our studies provide strong rationale for the near-term development of specific HDAC3 inhibitors for the treatment of CRPC.

HOXB13 is a member of the homeodomain family of sequence-specific transcription factors and, together with the androgen receptor (AR), plays a critical role in the normal development of the prostate gland. We demonstrate here that, in prostate cancer cells, HOXB13 is a key determinant of the response to androgens. Specifically, it was determined that HOXB13 interacts with the DNA-binding domain of AR and inhibits the transcription of genes that contain an androgen-response element (ARE). In contrast, the AR:HOXB13 complex confers androgen responsiveness to promoters that contain a specific HOXB13-response element. Further, HOXB13 and AR synergize to enhance the transcription of genes that contain a HOX element juxtaposed to an ARE. The profound effects of HOXB13 knockdown on androgen-regulated proliferation, migration, and lipogenesis in prostate cancer cells highlight the importance of the observed changes in gene expression.

BACKGROUND: The purpose of the current study was to prevent bloodstream infection and invasive fungal infection (IFI) by administering prophylactic antibiotic and antifungal agents during intensive chemotherapy in patients being treated for acute leukemia. METHODS: Prophylaxis treatment was administered during intensive chemotherapy in children with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) from January 1, 2010 to December 31, 2012. Oral ciprofloxacin (at a dose of 300 mg/m(2) /12 hours) was administered after chemotherapy when a patient with AML or ALL became neutropenic and > 7 days of neutropenia was expected. Voriconazole (at a dose of 4 mg/kg/12 hours) was initiated at the onset of neutropenia in patients with AML and after 7 days of neutropenia in patients with ALL. Micafungin (at a dose of 2 mg/kg/day) was substituted for voriconazole when patients with ALL received vincristine. Prophylaxis treatment was discontinued when the absolute neutrophil count recovered to > 100/µL. All episodes of bloodstream infection, IFI, febrile neutropenia, and intensive care unit stays related to severe infection occurring between January 1, 2005 and December 31, 2012 were recorded. RESULTS: During the preprophylaxis period, 62 children with ALL and 24 children with AML experienced a total of 44 episodes of bloodstream infection and 22 episodes of IFI. Seven patients died of severe infection. In contrast, in the prophylaxis period, 10 episodes of bloodstream infection occurred and no IFIs were reported to occur in 51 patients with ALL and 14 patients with AML. Moreover, no patient died of severe infection. Episodes of febrile neutropenia and intensive care unit stay were significantly reduced during the prophylaxis period. CONCLUSIONS: Prophylaxis with ciprofloxacin and voriconazole or micafungin was found to reduce the rates of bloodstream infection and IFI in children with acute leukemia undergoing intensive chemotherapy.

A series of unsymmetrically substituted biphenyl compounds was designed as alpha helical proteomimetics with the aim of inhibiting the binding of coactivator proteins to the nuclear hormone receptor coactivator binding domain. These compounds were synthesized in good overall yields in seven steps starting from 2-bromoanisole. The final products were evaluated using cotransfection reporter gene assays and mammalian two-hybrid competitive inhibition assays to demonstrate their effectiveness as competitive binding inhibitors. The results from this study indicate that these proteomimetics possess the ability to inhibit coactivator-receptor interactions, but via a mixed mode of inhibition.

Stimulation of resting CD4(+) T lymphocytes leads to rapid proliferation and differentiation into effector (Teff) or inducible regulatory (Treg) subsets with specific functions to promote or suppress immunity. Importantly, Teff and Treg use distinct metabolic programs to support subset specification, survival, and function. Here, we describe that the orphan nuclear receptor estrogen-related receptor-α (ERRα) regulates metabolic pathways critical for Teff. Resting CD4(+) T cells expressed low levels of ERRα protein that increased on activation. ERRα deficiency reduced activated T-cell numbers in vivo and cytokine production in vitro but did not seem to modulate immunity through inhibition of activating signals or viability. Rather, ERRα broadly affected metabolic gene expression and glucose metabolism essential for Teff. In particular, up-regulation of Glut1 protein, glucose uptake, and mitochondrial processes were suppressed in activated ERRα(-/-) T cells and T cells treated with two chemically independent ERRα inhibitors or by shRNAi. Acute ERRα inhibition also blocked T-cell growth and proliferation. This defect appeared as a result of inadequate glucose metabolism, because provision of lipids, but not increased glucose uptake or pyruvate, rescued ATP levels and cell division. Additionally, we have shown that Treg requires lipid oxidation, whereas Teff uses glucose metabolism, and lipid addition selectively restored Treg--but not Teff--generation after acute ERRα inhibition. Furthermore, in vivo inhibition of ERRα reduced T-cell proliferation and Teff generation in both immunization and experimental autoimmune encephalomyelitis models. Thus, ERRα is a selective transcriptional regulator of Teff metabolism that may provide a metabolic means to modulate immunity.

BACKGROUND/PURPOSE: Patients with acute myeloid leukemia (AML) and hyperleukocytosis, defined as an initial white blood cell (WBC) count of ≥ 100 × 10(9)/L, are often treated with leukapheresis. In this study, we have reported our experience of treating AML without leukapheresis. METHODS: From November 1, 1995, to May 31, 2012, there were 74 children (≤18 years old) with de novo AML other than acute promyelocytic leukemia. Seventeen patients had an initial WBC count ≥ 100 × 10(9)/L. Prompt chemotherapy was started within hours whereas leukapheresis was not performed. RESULTS: The median age of the 17 patients with hyperleukocytosis was 7.4 years (range: 0-16 years), and the median initial WBC count was 177 × 10(9)/L (range: 117-635 × 10(9)/L). The median time between admission and initiation of chemotherapy was 4.5 hours (range: 2-72 hours) in patients with hyperleukocytosis, whereas it was 13 hours (range: 2-120 hours) in those without hyperleukocytosis. Seven patients (7/17, 41%) had one or more early complications before or during the first 2 weeks of chemotherapy. Fifteen of the 16 patients who received prompt chemotherapy achieved complete remission (93.8%), comparable with those without hyperleukocytosis (98.2%; p = 0.33). CONCLUSION: Children with AML and hyperleukocytosis, treated with prompt chemotherapy without leukapheresis, had minimal early morbidities.

BACKGROUND: In the field of nursing education, the expertise and knowledge required to perform Leopold's Maneuvers are critical, forming an integral part of Entrustable Professional Activities for nursing students. As a result, mastering Leopold's Maneuvers has become a core component of nursing education. Despite this, the prevailing didactic methods in many nursing courses tend to limit interactive and contextual learning experiences, which can hinder students' ability to engage deeply with the subject matter. This lack of engagement may subsequently affect both the effectiveness of students' learning and students' clinical judgment capacity, essential elements in the competencies of Entrustable Professional Activities. METHODS: A quasi-experimental design was employed in this study, involving a total of 55 nursing university students, with 28 participants in the experimental group and 27 in the control group. The research incorporated game-based learning integrated with the self-regulated learning strategy, and employed a pretest, posttest, and questionnaires to assess students' learning performance, self-efficacy, and learning motivation. The experimental group participated in game-based learning with the self-regulated learning strategy, whereas the control group experienced game-based learning without the integration of self-regulated learning. Learning performance was analyzed using an independent samples t-test, while Analysis of Covariance was employed to compare the self-efficacy and learning motivation of the two groups. RESULTS: The findings showed that the integration of game-based learning with the self-regulated learning strategy can significantly improve students' learning performance, self-efficacy, and learning motivation. CONCLUSION: As an integral part of Entrustable Professional Activities, Leopold's Maneuvers were integrated into an interactive game-based learning environment, coupled with the self-regulated learning strategy in nursing education. This approach aimed at cultivating core competencies among nursing students. This study has demonstrated its efficacy in engaging students effectively, serving as a dynamic resource for immersive learning in Leopold's Maneuvers, aligning well with the design considerations for promoting Entrustable Professional Activities in nursing education.

BACKGROUND: Aging and dementia are common and closely related health problems in older adults, affecting their ability to maintain a healthy diet and ultimately resulting in malnutrition. OBJECTIVE: In this study, we estimated the global prevalence of malnutrition and malnutrition risk in older adults with dementia. DESIGN: Meta-analysis. DATA SOURCES: Embase, Ovid MEDLINE, PubMed, CINAHL, Scopus, and Web of Science were comprehensively searched for articles published from database inception to October 2022. METHODS: Pooled prevalence analysis was conducted using a generalized linear mixed model and a random-effects model. I2 and Cochran's Q statistics were used for identifying heterogeneity. Publication bias was evaluated using Peters' regression test and a funnel plot. Moderator analyses were conducted to investigate variations in the prevalence estimates of the included studies. All statistical analyses were conducted using R software. RESULTS: A total of 16 studies involving a total of 6513 older adults with dementia were included in the analysis. The results indicated that 32.52â¯% (95â¯% confidence interval: 19.55-45.49) of all included older adults with dementia had malnutrition, whereas 46.80â¯% (95â¯% confidence interval: 38.90-54.70) had a risk of malnutrition. The prevalence of malnutrition was found to be high among older patients living in institutionalized settings (46.59â¯%) and those with Alzheimer's disease (12.26â¯%). The factors moderating the prevalence of malnutrition included adequate vitamin B12 consumption, risk behaviors, medical comorbidities, and certain neuropsychiatric symptoms. The prevalence of malnutrition risk was high among women (29.84â¯%) and patients with Alzheimer's disease (26.29â¯%). The factors moderating the prevalence of malnutrition risk included total cholesterol level, vitamin B12 consumption, risk behaviors, medical comorbidities, and certain neuropsychiatric symptoms. CONCLUSIONS: Approximately one-third of older adults with dementia are malnourished and nearly half of older adults are at a risk of malnutrition. Encouraging collaboration among health-care professionals and ensuring early assessment and effective management of malnutrition are crucial for maintaining a favorable nutritional status in older adults with dementia. REGISTRATION: This study was registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42022369329). TWEETABLE ABSTRACT: Globally, approximately 32.52â¯% of older adults with dementia are malnourished and approximately 46.80â¯% are at a risk of malnutrition.
