Gerontological educational interventions for student nurses: a systematic review of qualitative findings.

OBJECTIVES: This systematic review of qualitative studies explored interventions to improve student nurses' knowledge, attitudes or willingness to work with older people. Student nurses are likely to encounter older people in all health and aged care settings, however, research demonstrates that few have career aspirations in gerontological nursing. METHODS: Qualitative systematic review method based on the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: Search of Medline, Embase, PsycINFO, EBSCOhost and Scopus yielded 1841 articles which were screened to include primary research about educational interventions to improve student nurses' knowledge, attitudes and/or willingness to work with older people. Data extraction was performed on the 14 included studies, and data were analysed using directed content analysis. The Mixed Methods Appraisal Tool (MMAT) was used the assess the quality of the studies. CONCLUSIONS: Educational interventions included theory or practice courses, or a combination of theory and practice. While most interventions changed nursing students' negative attitudes towards older people, few increased their willingness to work with them. Practice courses had the most significant impact on willingness to work with older people. Quality assessment revealed methodical limitations. More research is needed to better understand the elements of practice interventions that enhance student nurses' knowledge, attitudes, and willingness to work with older people, so that they can be replicated.

Beneficios y limitaciones de la planificación centrada en la persona en el campo de la discapacidad intelectual y del desarrollo: una revisión sistemática según las directrices de PRISMA / Benefits and limitations of person-centered planning in the field of intellectual and developmental disabilities: a systematic review according to PRISMA guidelines

La metodología de Planificación Centrada en la Persona (PCP) cada vez tiene mayor impacto en España. Comenzando desde las distintas legislaciones que regulan la atención a este colectivo en las diferentes autonomías y terminando en los centros que proveen este servicio. No obstante, existe escasa literatura internacional de estudios empíricos a grandes escalas que sitúen este enfoque metodológico en una posición relevante que garantice la eficacia de la PCP. El objetivo principal de este estudio es conocer el estado del uso de la metodología de PCP a través de estudios avalados empíricamente que sostengan tanto beneficios como limitaciones durante los últimos 10 años (2012-2022). Para ello, se ha realizado una revisión sistemática desde las directrices de PRISMA (2020), que incluye un total de 31 artículos. Como conclusión, se han descubierto más beneficios que limitaciones entre las que destacan las ventajas en su uso para las personas con discapacidad intelectual y del desarrollo y las mejoras de aspectos relacionados con la autodeterminación. No obstante, las limitaciones prevalecen por la falta de apoyos y recursos adecuados de las organizaciones para responder a una planificación centrada en la persona y la necesidad de formación de las personas implicadas en la elaboración de la PCP, lo que genera la incógnita de si se están realizando buenas prácticas en el uso de dicha metodología. (AU)

The methodology of Person Centered Planning (PCP) is having an increasing impact in Spain. Starting from the different legislations that regulate the attention to this group in the different autonomous regions and ending in the centers that provide this service. However, there is little international literature on large-scale empirical studies that place this methodological approach in a relevant position to guarantee the efficacy of PCP. The main objective of this study is to know the status of the use of PCP methodology through empirically supported studies that sustain both benefits and limitations during the last 10 years (2012-2022). For this purpose, a systematic review has been conducted since the PRISMA guidelines (2020), including a total of 31 articles. As a conclusion, more benefits than limitations have been found, among which the advantages in its use for people with intellectual and developmental disabilities and improvements in aspects related to self-determination stand out. However, limitations prevail due to the lack of adequate support and resources from organizations to respond to person-centered planning and the need for training of the people involved in the development of the PCP, which raises the question of whether good practices are being carried out in the use of this methodology.

Terapia de Aceptación y Compromiso en conducta suicida: una revisión sistemática / Acceptance and Commitment Therapy on suicidal behavior: a systematic review

El suicidio se ha convertido en un problema social y de salud pública a nivel mundial. En este sentido, la Terapia de Aceptación y Compromiso (ACT) podría ser eficaz en su abordaje, existiendo evidencia sobre la relación entre algunos de sus componentes y la conducta suicida. Así, el presente estudio tuvo por objetivo realizar una revisión sistemática sobre la eficacia de ACT en conducta suicida. Para ello se siguió el protocolo PRISMA, empleando las siguientes bases de datos: PsycInfo, PubMed, Scopus y PsicoDoc. Inicialmente se obtuvieron 108 publicaciones potencialmente relevantes, de las cuales, finalmente, 13 fueron incluidas en la revisión. La calidad de los estudios se analizó a través de un instrumento de evaluación de riesgo de sesgos. Como resultados, a nivel general se observaron disminuciones estadísticamente significativas en ideación suicida (IS) y factores de riesgo de suicidio. Además, algunos estudios señalaron relaciones estadísticamente significativas entre un aumento de flexibilidad psicológica y la disminución de IS. Si bien los datos apuntaron a una posible eficacia de ACT en la reducción de IS, es necesario llevar a cabo mayor número de estudios experimentales que contemplen la complejidad de la conducta suicida y exploren los procesos de cambio implicados.(AU)

Suicide has emerged as a pressing global issue affecting both so-ciety and public health.In this context, Acceptance and Commitment Therapy (ACT) could prove effective in its approach, supported by evi-dence of the relationship between certain components of ACT and suicidal behavior. Thus, the present study aims to conduct a systematic review on the efficacy of ACT in suicidal behavior. For this, the PRISMA protocol was followed, using thefollowing databases: PsycInfo, PubMed, Scopus and PsicoDoc.

Factores de riesgo transdiagnósticos de los trastornos emocionales en adultos: una revisión sistemática / Transdiagnostic risk factors of emotional disorders in adults: A systematic review

La comorbilidad es más la regla que la excepción en salud mental y, sobre todo, en el caso de la ansiedad y la depresión. Los modelos transdiagnósticos estudian los procesos subyacentes para mejorar el tratamiento y la comprensión de la salud mental. Objetivo: Esta revisión sistemática busca evidencias sobre los factores de riesgo transdiagnósticos para la ansiedad y la depresión en la población clínica diagnosticada de estas condiciones psicopatológicas, analizando los diferentes tipos o categorías de factores identificados. Método: Se registró una revisión sistemática en PROSPERO (número de registro CRD42022370327) y se diseñó de acuerdo con las guías PRISMA-P. La calidad del estudio fue evaluada por dos revisores independientes con conocimiento del campo para reducir el posible sesgo. Resultados: Cincuenta y tres artículos fueron examinados y las variables transdiagnósticas fueron agrupadas en tres categorías: psicológicas, biológicas y socioculturales. Conclusiones: La categoría más estudiada fue la de variables psicológicas, en especial los procesos cognitivos, afecto negativo y neuroticismo, intolerancia a la incertidumbre, sensibilidad a la ansiedad. Los factores biológicos y socioculturales requieren más estudio para sustentar su enfoque transdiagnóstico.(AU)

Comorbidity is more the rule than the exception in mental health, specifically in the case of anxiety and depression. Transdiagnostic models studied the underlying processes to improve mental health treat-ment and understating. Objective:This systematic review searchs for evi-dence on transdiagnostic risk factors for anxiety and depression in the clin-ical population diagnosed with these psychopathological conditions, by an-alysing the different types or categories of factors identified.Methods:A sys-tematic review was registered in PROSPERO (registration number CRD42022370327) and was designed according to PRISMA-P guidelines. Two independent reviewers with field knowledge assessed the study quality to reduce bias.Results: Fifty-three articles were examined, and the transdi-agnostic variables were grouped into three categories: psychological, bio-logical, and sociocultural.Conclusions:The most studied category was that of psychological variables, especially cognitive processes, negative affect, and neuroticism, intolerance of uncertainty, anxiety sensitivity. Biological and sociocultural factors require more study to support their transdiagnos-tic approach.(AU)

Comparing the long-term follow-up anal function between robot-assisted and laparoscopic surgery for low rectal cancer: A meta-analysis and systematic review.

BACKGROUND: Robotic-assisted surgery (RAS) is increasingly used for treating low rectal cancer. Its comparative effectiveness against laparoscopic surgery (LAS) in enhancing long-term anal function remains uncertain. METHODS: A meta-analysis was conducted to compare long-term anal function outcomes between patients undergoing RAS and LAS. Meta-regression and sensitivity analyses were performed to assess available evidence. Studies published up to September 2023 in English or Chinese were included. RESULTS: Seven studies were identified. RAS patients exhibited lower low anterior resection syndrome (LARS) scores (standardised mean difference [SMD] = -1.39; 95% confidence interval [CI]: -2.64 to -0.15) and Wexner scores (SMD = -0.74; 95% CI: -1.20 to -0.27) compared with LAS patients. However, RAS did not significantly reduce major LARS risk (odds ratio = 0.85; 95% CI: 0.68-1.04). CONCLUSIONS: RAS slightly improved postoperative anal function compared with LAS. Further studies with large samples are warranted to confirm or update our findings.

Circulating Levels of Calprotectin as a Biomarker in Patients With Coronary Artery Disease: A Systematic Review and Meta-Analysis.

BACKGROUND: Calprotectin, also known as MRP8/14, is generated by immune cells and is altered in several inflammatory diseases. Studies have assessed their levels in patients with coronary artery disease (CAD) and its subtypes (stable CAD and acute coronary syndrome [ACS]). Herein, we aimed to systematically investigate these associations through a systematic review and meta-analysis. METHODS: A systematic search was conducted in four online databases, including PubMed, Scopus, Embase, and the Web of Science. Relevant studies were retrieved, screened, and extracted. Random-effect meta-analysis was performed for the calculation of standardized mean difference (SMD) and 95% confidence interval (CI). Blood calprotectin levels were compared between CAD patients and controls, as well as CAD subtypes. RESULTS: A total of 20 studies were included in the systematic review and meta-analysis, comprising 3300 CAD patients and 1230 controls. Patients with CAD had significantly higher calprotectin levels (SMD 0.81, 95% CI 0.32-1.30, p < 0.01). Similarly, patients with ACS were reported to have higher levels compared to those with stable CAD. However, there was no significant difference in terms of blood calprotectin levels between stable CAD cases and healthy controls. Finally, studies have shown that calprotectin could be used as a diagnostic biomarker of CAD while also predicting major adverse events and mortality in these patients. CONCLUSION: Based on our findings, calprotectin, as an inflammatory marker, could be used as a possible biomarker for patients with CAD and ACS. These suggest the possibility of pathophysiological pathways for this involvement and warrant further research on these associations as well as their clinical utility.

Clinical and radiographic success rate of the root canal filling materials used in primary teeth: A systematic review.

One of the most important factors that determine the success of pulpectomy in primary teeth is the root canal filling material used. This systematic review is an update on the success rates of various materials used for obturation in primary teeth. An electronic search was carried out in the PubMed, Scopus, Web of Science, and Cochrane Library databases with the preset inclusion and exclusion criteria. Only randomized or quasi-randomized clinical and controlled trials with a minimum follow-up of 12 months were included for analysis. Nine articles were considered potentially eligible for inclusion in this review. All the included trials had zinc oxide-eugenol (ZOE) cement as a control group. The time span of the included trials extended from 12 to 30 months. Only 2 trials were at low risk of bias. Evidence to support the success rates of obturating materials used in primary teeth is scarce, which necessitates further highquality randomized controlled clinical trials with regard to this issue.

Nasogastric tube versus postpyloric tube feeding for critical illness: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES: Gastric tube feeding and postpyloric tube feeding are two common forms of enteral nutrition in critically ill patients. This study aimed to compare the efficacy and safety of gastric tube feeding with that of postpyloric tube feeding in critically ill patients. METHODS AND STUDY DESIGN: PubMed, Embase, and Cochrane Library were systematically searched for eligible trials from their inception until March 2023. Relative risks (RRs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs) were used to estimate categorical and continuous outcomes using the random-effects model. RESULTS: Sixteen trials involving 1,329 critically ill patients were selected for the final meta-analysis. Overall, we noted that gastric tube feeding showed no significant difference from post-pyloric tube feeding in mortality (p = 0.891), whereas the risk of pneumonia was significantly increased in patients who received gastric tube feeding (RR: 1.45; p = 0.021). Furthermore, we noted that gastric tube feeding was associated with a shorter time required to start feeding (WMD: -11.05; p = 0.007). CONCLUSIONS: This research revealed that initiating feeding through the gastric tube required less time compared to postpyloric tube feeding. However, it was also associated with a heightened risk of pneumonia among critically ill patients.

Intermittent fasting modulates human gut microbiota diversity in a phenotype-dependent manner: a systematic review.

Cumulative evidence suggests that intermittent fasting (IF) has beneficial effects on human metabolic health. It has been indicated that its impact on the gut microbiota may mediate these beneficial effects. As a result, we hypothesized that IF may impact the human gut microbiota. A systematic review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) protocol using the PubMed, Scopus, and CINAHL databases. We registered our systematic review protocol in PROSPERO under registration number CRD42021270050. Human intervention studies published until April 30, 2023, were included. The quality of the included studies was assessed using National Institutes of Health (NIH) quality assessment study tools for intervention studies. The search in the database returned 166 studies, of which 13 matched all criteria for the final qualitative analysis. The body of evidence suggests that IF modulates human gut microbiota alpha and beta diversity in lean (relatively healthy) and relatively healthy overweight/obese individuals but not in individuals with metabolic syndrome. Furthermore, IF also alters human gut microbiota composition in all phenotypes. Of interest, the gut microbiota taxa or microbial metabolites after an IF intervention are associated with metabolic markers. According to this review, IF influences the diversity and taxonomic levels of the human gut microbiota. Individual metabolic phenotypes may alter the effect of IF on the diversity and taxonomic levels of the gut microbiota.

Non-ictal, interictal and ictal déjà vu: a systematic review and meta-analysis.

Background: Déjà vu, French for "already seen," is a phenomenon most people will experience at least once in their lifetime. Emerging evidence suggests that déjà vu occurs in healthy individuals (as "non-ictal déjà vu") and in epilepsy patients during seizures (as "ictal déjà vu") and between seizures (as "interictal déjà vu"). Although the ILAE has recognized déjà vu as a feature of epileptic seizures, it is notably absent from the ICD-11. A lack of evidence-based research may account for this omission. To our knowledge, this study represents the first systematic review and meta-analysis on déjà vu experiences. Through detailed examinations of non-ictal, interictal and ictal déjà vu, we seek to highlight possible clinical implications. Rethinking the status quo of ictal déjà vu could potentially lead to earlier interventions and improve outcomes for epilepsy patients. Methods: This study was registered in PROSPERO (ID: CRD42023394239) on 5 February 2023. Systematic searches were conducted across four databases: EMBASE, MEDLINE, PsycINFO, and PubMed, from inception to 1 February 2023, limited to English language and human participants. Studies were included/excluded based on predefined criteria. Data was extracted according to the PICO framework and synthesized through a thematic approach. Meta-analyses were performed to estimate prevalence's of the phenomena. Study quality, heterogeneity, and publication bias were assessed. Results: Database searching identified 1,677 records, of which 46 studies were included. Meta-analyses of prevalence showed that non-ictal déjà vu was experienced by 0.74 (95% CI [0.67, 0.79], p < 0.001) of healthy individuals, whereas interictal déjà vu was experienced by 0.62 (95% CI [0.48, 0.75], p = 0.099) and ictal déjà vu by 0.22 (95% CI [0.15, 0.32], p = 0.001) of epilepsy patients. Examinations of phenomenological (sex, age, frequency, duration, emotional valence, and dissociative symptoms) and neuroscientific (brain structures and functions) data revealed significant variations between non-ictal, interictal and ictal déjà vu on several domains. Conclusion: This systematic review and meta-analysis do not support the notion that non-ictal, interictal and ictal déjà vu are homogenous experiences. Instead, it provides insight into ictal déjà vu as a symptom of epilepsy that should be considered included in future revisions of the ICD-11.

Effect of Elevated Neutrophil-to-Lymphocyte Ratio on Adverse Outcomes in Patients With Myocardial Infarction: A Systematic Review and Meta-Analysis.

Myocardial infarction (MI), a leading cause of morbidity and mortality globally, is characterized by an underlying inflammatory process driven by atherosclerosis. The neutrophil-to-lymphocyte ratio (NLR), a readily available and cost-effective marker of systemic inflammation, has emerged as a potential predictor of adverse outcomes in patients with MI. This meta-analysis aimed to evaluate the association between elevated NLR and the risk of major adverse cardiovascular events (MACE) and all-cause mortality in patients with MI. A comprehensive literature search was conducted across multiple databases, including Embase, Web of Science, PubMed, and OVID Medicine, to identify relevant studies published from January 1, 2011, onward. Studies reporting the effect of NLR values on MACE and mortality in adult patients with MI, including both ST-elevation (STEMI) and non-ST-elevation (NSTEMI) subtypes, were included. Data extraction and quality assessment were performed independently by multiple authors. The meta-analysis included 37 studies, comprising a total of 18 studies evaluating the risk of MACE and 30 studies assessing all-cause mortality. The pooled analysis revealed a significantly increased risk of MACE (odds ratio [OR] 1.86, 95% confidence interval [CI] 1.53-2.28, P < 0.01) and all-cause mortality (OR 2.29, 95% CI 1.94-2.70, P < 0.01) in patients with elevated NLR compared to those without elevated NLR. Subgroup analyses stratified by follow-up duration and study design further supported the consistent association between elevated NLR and adverse outcomes. In conclusion, this meta-analysis demonstrates a significant association between elevated NLR and an increased risk of MACE and all-cause mortality in patients with MI. These findings highlight the potential clinical utility of NLR as a prognostic marker and underscore the importance of further research to validate its predictive value and establish optimal cutoff values for risk stratification in this patient population.

Clinical Performance of Implant-Supported Prostheses in the Rehabilitation of Patients Previously Treated for Medication-Related Osteonecrosis of the Jaws (MRONJ): A Systematic Review.

There is a lack of consensus on managing resultant bone and soft tissue defects or on restoring oral function and aesthetics following medication-related osteonecrosis of the jaws (MRONJ) lesion healing. This clinical challenge presents a dilemma for practitioners. Removable prostheses pose a recurrence risk if poorly fitted and may inadequately restore function or aesthetics in cases of significant bone defect. Dental implant-supported prostheses could enhance function and quality of life, though their risks and indications are not well-defined. This systematic review examines the clinical outcomes and complications associated with implant-supported rehabilitations post-MRONJ surgery. This study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement recommendations and it was pre-registered in the Prospective Register of Systematic Reviews (PROSPERO) (CRD42023492539).

Embolization coils in treating postoperative bronchopleural fistula: a systematic review.

Objective: This study aims to comprehensively evaluate embolization coils in treating postoperative bronchopleural fistula (BPF). Methods: A systematic review based on PubMed, Embase, and The Cochrane Library studies was conducted. All cases receiving embolization coils in treating postoperative BPF were included. The primary outcome was the efficacy of embolization coils in achieving closure of postoperative BPF. Results: 20 patients from 9 studies were included in this systematic review. A median number of 3 (range: 1-10) embolization coils with sealants obtained a complete closure rate of 80% in patients with postoperative BPF with sizes ranging from 2 to 3.1 mm. Three patients with BPF over 3 mm and one with multiple organ failure failed this treatment. Two cases of coil migration were reported without causing respiratory failure or fistula recurrence. Conclusion: Embolization coils might be considered a safe and effective bronchoscopic treatment for small postoperative BPF of less than 3 mm in size. More extensive and rigorous studies are needed to further evaluate and confirm the optimal use of embolization coils in the context of an alternative to surgical repair.

Comparing the Scores of The Functional Movement Screen™ in Individuals with Low Back Pain versus Healthy Individuals: A Systematic Review and Meta-Analysis.

Background: The Functional Movement Screen™ (FMS™) is widely used to assess functional movement patterns and illuminate movement dysfunctions that may have a role in injury risk. However, the association between FMS™ scores and LBP remains uncertain. Objective: The purpose of this systematic review and meta-analysis was to examine functional movement scores among patients with low back pain (LBP) and healthy subjects with no LBP and review the validity of the FMS™ tool for screening functional movement among LBP patients. Methods: The systematic review and meta-analysis included papers assessing functional movement among adult patients with LBP using the FMS™ through a literature review of five databases. The search strategy focused used relevant keywords: Functional movement screen AND low back pain. The review included all papers assessing functional movement among LBP adult patients (>18 years old) using the FMS™ published between 2003 to 2023. The risk of bias in the involved studies was evaluated using the updated Cochrane ROB 2 tool. Statistical analysis was conducted using Review Manager software, version 5.4. The meta-analysis included the total FMS™ score and the scores of the seven FMS™ movement patterns. Results: Seven studies were included in this systematic review were considered to have low to unclear risk of bias. The meta-analysis revealed that the LBP group had a significantly lower total FMS™ score than the control group by 1.81 points (95% CI (-3.02, -0.59), p= 0.004). Patients with LBP had a significantly lower score than the control group regarding FMS™ movement patterns, the deep squat (p <0.01), the hurdle step (p <0.01), the inline lunge (P value <0.01), the active straight leg raise (p <0.01), the trunk stability push-up (p=0.02), and the rotational stability screens (p <0.01). Conclusion: Lower scores on the FMS™ are associated with impaired functional movement. Identifying the specific functional movement impairments linked to LBP can assist in the creation of personalized treatment plans and interventions. Further research is needed to assess the association of cofounders, such as age, gender, and body mass index, with the FMS™ score among LBP patients and controls. Level of evidence: 1.

A research synthesis of humans, animals, and environmental compartments exposed to PFAS: A systematic evidence map and bibliometric analysis of secondary literature.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are a class of widely used anthropogenic chemicals. Concerns regarding their persistence and potential adverse effects have led to multiple secondary research publications. Here, we aim to assess the resulting evidence base in the systematic secondary literature by examining research gaps, evaluating the quality of reviews, and exploring interdisciplinary connections. METHODS: This study employed a systematic evidence-mapping approach to assess the secondary literature on the biological, environmental, and medical aspects of exposure to 35 fluorinated compounds. The inclusion criteria encompassed systematic reviews published in peer-reviewed journals, pre-prints, and theses. Comprehensive searches across electronic databases and grey literature identified relevant reviews. Data extraction and synthesis involved mapping literature content and narrative descriptions. We employed a modified version of the AMSTAR2 checklist to evaluate the methodological rigour of the reviews. A bibliometric data analysis uncovered patterns and trends in the academic literature. A research protocol for this study was previously pre-registered (osf.io/2tpn8) and published (Vendl et al., Environment International 158 (2022) 106973). The database is freely accessible through the interactive and user-friendly web application of this systematic evidence map at https://hi-this-is-lorenzo.shinyapps.io/PFAS_SEM_Shiny_App/. RESULTS: Our map includes a total of 175 systematic reviews. Over the years, there has been a steady increase in the annual number of publications, with a notable surge in 2021. Most reviews focused on human exposure, whereas environmental and animal-related reviews were fewer and often lacked a rigorous systematic approach to literature search and screening. Review outcomes were predominantly associated with human health, particularly with reproductive and children's developmental health. Animal reviews primarily focused on studies conducted in controlled laboratory settings, and wildlife reviews were characterised by an over-representation of birds and fish species. Recent reviews increasingly incorporated quantitative synthesis methodologies. The methodological strengths of the reviews included detailed descriptions of study selection processes and disclosure of potential conflicts of interest. However, weaknesses were observed in the critical lack of detail in reporting methods. A bibliometric analysis revealed that the most productive authors collaborate within their own country, leading to limited and clustered international collaborations. CONCLUSIONS: In this overview of the available systematic secondary literature, we map literature content, assess reviews' methodological quality, highlight data gaps, and draw research network clusters. We aim to facilitate literature reviews, guide future research initiatives, and enhance opportunities for cross-country collaboration. Furthermore, we discuss how this systematic evidence map and its publicly available database benefit scientists, regulatory agencies, and other stakeholders by providing access to current systematic secondary literature on PFAS exposure.

Effectiveness of interventions for informal caregivers of community-dwelling frail older adults: A systematic review and meta-analysis.

AIM: Systematic reviews on interventions for informal caregivers of community-dwelling frail older adults were published over a decade ago and they mistook frailty for other severe age-related conditions like disability and dementia. Therefore, this study aimed to systematically synthesize these interventions supporting these caregivers identified by an acknowledged frailty assessment instrument and to examine their effectiveness on caregiver-related outcomes. DESIGN: Systematic review and meta-analysis. DATA SOURCES: Fourteen electronic databases, grey literature and reference lists were systematically searched for randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) from inception to November 3, 2023. METHODS: Methodology quality and risk of bias were assessed. Data were meta-analysed using the Comprehensive Meta-Analysis, version 3.0. Studies and outcomes unsuitable for meta-analysis were summarized by narrative syntheses. RESULTS: Four studies consisting of three RCTs and one NRCT were included involving 350 participants. Interventions for caregivers of frail older adults included multicomponent interventions (n = 3) and education intervention (n = 1). Interventions had a moderate effect on reducing depression and showed nonsignificant effects on caregiver burden, caregiving time or quality of life (QoL). The PEDro scores for RCTs ranged from 6 to 8, indicating good methodologic quality, but were all judged as high risk of bias. The NRCT reported all methodologic aspects and was at low risk of bias. CONCLUSIONS: Few studies focus on interventions targeting caregivers of frail older adults, and their effectiveness may vary by outcomes. This review suggested the potential benefits of these interventions in reducing caregivers' depression. IMPACT: The differential effectiveness by outcomes and high risk of bias of studies implicate that more rigorous studies are warranted.

Prevalence of sleep disturbances in people with mild cognitive impairment: A systematic review and meta-analysis.

This review was performed to determine sleep disturbance prevalence in individuals with mild cognitive impairment (MCI). The MEDLINE, Embase, Cochrane Library, CINAHL, PsycINFO, and Web of Science databases were systematically searched from inception to January 20, 2024. Fifty-two studies fulfilling the eligibility criteria were included. However, six of these studies were excluded from data synthesis due to poor methodological quality. The subjective sleep disturbance prevalence among all individuals with MCI was 35.8 % (95 % CI: 31.9-39.7) across 44 studies, and the objective sleep disturbance prevalence was 46.3 % (95 % CI: 36.3-56.3) across 6 studies. Five studies examined TST and WASO, while three assessed SE. Among all potential objective assessments of sleep disturbance prevalence, only TST, WASO, and SE could be meta-analyzed in MCI because of the limited number of studies available. The estimated sleep disturbance prevalence differed significantly according to measurement method, geographical region, and research design. However, the data source did not significantly influence prevalence estimates. In meta-regression analysis, publication year, participant age, percentage of females, and study quality did not predict prevalence. As subjective and objective sleep disturbances are common in people with MCI, effective intervention strategies should be developed to alleviate them.

Simulation-based education for teaching aggression management skills to healthcare providers in acute healthcare settings: A systematic review.

BACKGROUND: Behavioural emergencies involving aggression in acute care hospitals are increasing globally. Acute care staff are often not trained or confident in their prevention or management. Of available training options simulation-based education is superior for clinical medical education and is gaining acceptance for teaching clinical aggression management skills. OBJECTIVE: The aim of this study was to conduct a systematic review of the effectiveness of simulation-based education for teaching aggression management skills for health professionals working in acute healthcare settings. METHODS: The study protocol was prepared in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) statement, registered (27/02/2020) and published. We included randomised controlled trials, non-randomised controlled trials, quasi-experimental studies, and observational studies involving healthcare professionals in acute hospital settings or trainee health professionals who received simulation-based training on managing patient aggression. Comprehensive searches were conducted in PubMed, Ovid MEDLINE, PsycINFO, CINAHL and The Cochrane Library. Two reviewers independently screened all records, extracted data and assessed risk of bias. The primary outcomes included patient outcomes, quality of care, and adverse effects. Secondary outcomes included workplace resource use, healthcare provider related outcomes, knowledge (de-escalation techniques), performance, attitudes, and satisfaction. A narrative synthesis of included studies was performed because substantial variation of interventions and outcome measures precluded meta-analyses. RESULTS: Twenty-five studies were included with 2790 participants, 2585 (93 %) acute care hospital staff and 205 (7 %) undergraduate university students. Twenty-two studies combined simulation-based education with at least one other training modality. Three studies were randomised controlled trials, one was a pilot and feasibility cluster randomised controlled trial, one was a three-group post-test design and twenty were pre-/post-test design. Twenty-four studies were deemed to be high/critical or serious risk of bias. Four studies collected primary outcome data, all using different methods and with inconsistent findings. Twenty-one studies assessed performance in the test situation, seven studies provided objective ratings of performance and eighteen provided self-report data. Twenty-three studies reported objective or subjective improvements in secondary outcomes. CONCLUSIONS: Acute healthcare staff who completed simulation-based education on managing clinical aggression showed statistically significant improvements in knowledge and self-reported confidence. However, there is a lack of evidence about the magnitude of these improvements and impact on patient outcomes. REGISTRATION: PROSPERO Registration Number CRD42020151002. TWEETABLE ABSTRACT: Simulation-based education improved acute healthcare clinician knowledge and confidence in managing aggression.

Systematic review and meta-analyses of cytisine to support tobacco cessation.

BACKGROUND AND AIMS: Cytisine (also known as cytisinicline) is a low-cost partial agonist of nicotinic acetylcholine receptors used to assist tobacco cessation. We aimed to review the effectiveness of cytisine for tobacco cessation and the effects of dose and co-use of behavioural or other pharmacological interventions on cessation outcomes. METHODS: We searched seven databases, Google Scholar, and reference lists of included publications for randomised controlled trials investigating use of cytisine as a tobacco cessation aid. Studies were eligible if participants were ≥15 years old and used tobacco upon study enrolment. We conducted four random effects meta-analyses and sensitivity analyses with fixed effects models. We used the Cochrane risk-of-bias tool for randomised trials version 2 to assess risk of bias in included studies, with adjustments recommended by the Cochrane Tobacco Addiction Group. RESULTS: Participants using cytisine were significantly more likely to quit tobacco than participants who received placebo/no intervention/usual care (risk ratio [RR] = 2.65, 95% confidence interval [CI] = 1.50-4.67, 6 trials, 5194 participants) or nicotine replacement therapy (RR = 1.36, 95% CI = 1.06-1.73, p = 0.0152, 2 trials, 1511 participants). The difference in cessation rates among participants receiving cytisine versus varenicline was not statistically significant (RR = 0.96, 95% CI 0.63-1.45, P = 0.8464, 3 trials, 2508 participants). Two trials examined longer versus shorter treatment duration, finding higher abstinence rates with longer treatment (RR = 1.29, 95% CI = 1.02-1.63, 2 trials, 1009 participants). The differences in the number of adverse events reported by participants who received cytisine versus placebo (RR = 1.19, 95% CI = 0.99-1.41, P = 0.0624; 6 trials; 4578 participants) or cytisine versus varenicline (RR = 1.37, 95% CI = 0.57-3.33, P = 0.4835; 2 trials; 1345 participants) were not statistically significant. Most adverse events were mild (e.g. abnormal dreams, nausea, headaches). CONCLUSIONS: Cytisine is an effective aid for tobacco cessation and appears to be more effective for tobacco cessation than placebo, no intervention, usual care and nicotine replacement therapy.
