BACKGROUND AND OBJECTIVES
In this systematic review, we assessed the efficacy, potential mechanisms, and safety of two neuromodulation therapies in patients with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. The first therapy is vagus nerve stimulation (VNS) utilizing implantable or transcutaneous electrodes, and the second is sacral nerve stimulation (SNS) using implantable or percutaneous electrodes.
METHODS
We conducted a systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The PubMed database was comprehensively searched, and studies were rigorously assessed for inclusion and exclusion criteria.
RESULTS
Our analysis encompassed five clinical studies, three on VNS and two on SNS. Most investigated studies demonstrated significant beneficial effects on IBD symptoms, including disease activity, severity of intestinal lesions, and intestinal pain. When evaluating the impact on key IBD pathophysiologies, both VNS and SNS exhibited trends toward reducing biomarkers of intestinal mucosal inflammation and mitigating sympathetic dominance. Importantly, none of the evaluated neuromodulation methods resulted in long-term adverse effects.
CONCLUSIONS
Cumulative evidence from the evaluated studies indicates that VNS and SNS therapies effectively alleviate IBD symptoms and may hold promise in addressing the underlying pathophysiologies of IBD, including intestinal mucosal inflammation and sympathetic dominance. Consequently, they represent valuable options for individualized IBD treatment.

Comparison of Effectiveness of High Dose Statin Monotherapy With Combination of Statin and Ezetimibe to Prevent Cardiovascular Events in Patients With Acute Coronary Syndrome: A Systematic Review and Meta-Analysis.
This meta-analysis aimed to compare the effectiveness of high statin monotherapy and a combination of statin and ezetimibe to prevent cardiovascular outcomes in patients with acute coronary syndrome (ACS). The study was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We conducted comprehensive searches across online databases, including MEDLINE/ PubMed, EMBASE, and the Web of Science, to find the relevant articles from the databases' inception to 10 Feb 2024. Outcomes assessed in the meta-analysis included major cardiovascular events (MACE), all-cause mortality, stroke, myocardial infarction, and unplanned revascularization. Data analysis was conducted utilizing RevMan Version 5.3.1. The comparison of outcomes between the two groups involved the calculation of risk ratios (RR) accompanied by 95% confidence intervals (CI) using either a random or fixed-effect model. Five studies were included in this meta-analysis, encompassing 48,668 patients. The pooled analysis showed that the risk of all-cause mortality was higher in patients receiving high statin monotherapy. However, no significant differences in MACE, myocardial infarction, stroke, and revascularization were reported. While acknowledging the limitations, including the lack of randomized controlled trials and the dominance of one study in the analysis, these findings underscore the importance of further research to clarify the comparative effectiveness of these treatment modalities in preventing cardiovascular outcomes in ACS patients.

Review
Neurofibromatosis Type 1 (NF1) is a genetic autosomal dominant disorder that affects both the central and peripheral nervous systems. Children and adolescents with NF1 commonly experience neuropsychological, motor, and behavioral deficits. The cognitive profile hallmark of this disorder includes visuospatial and executive function impairments. These cognitive disorders may persist into adulthood. This study aims to analyze previous research studies that have described cognitive dysfunctions in adults with NF1. The purpose of this analysis is to review the neuropsychological and psychological assessment methods used. A total of 327 articles were identified based on the search terms in their titles and abstracts. The evaluation was conducted by scrutinizing each article's title, abstract, and text. Only 16 articles were found to be eligible for inclusion based on the pre-defined criteria. The selected studies primarily focus on the development of diagnostic protocols for individuals with NF1. The management of NF1 disease requires a multidisciplinary approach to address symptoms, preserve neurological functions, and ensure the best possible quality of life. However, cognitive impairment can negatively affect psychological well-being. This study suggested that cognitive functions in NF1 patients were not tested using specific measures, but rather were evaluated through intelligence scales. Additionally, the findings revealed that there is no standardized neuropsychological assessment for adults with NF1. To address this gap, it would be helpful to create a specific neuropsychological battery to study cognitive function in NF1 patients during clinical studies. This battery could also serve as a tool to design models for cognitive rehabilitation by using reliable and sensitive measures of cognitive outcomes.

Review
Mental ill-health and suicide represent a significant proportion of the burden of global disease among men. Connell's relational theory of masculinities provides a useful framework to explore how mental health literacy, mental health stigma, and delayed help-seeking and help-offering behaviors are associated with mental ill-health among men, particularly within male-dominated industries. To address the high incidences of mental ill-health in male-dominated industries, several workplace interventions targeting these outcomes have been implemented. No review to date has examined the current state of evidence for these interventions or identified the behavior change techniques used. This review was restricted to empirical, quantitative research reporting on psychosocial interventions targeting mental health literacy, stigma, and help-seeking and help-offering behaviors in male-dominated industries. Quality appraisal was completed using the Effective Public Health Practice Project and a narrative synthesis was conducted. Twelve articles were included for review which reported on four distinct interventions. The methodological quality of two articles was strong, three moderate and seven weak. The strongest evidence of intervention effects related to mental health literacy and help-seeking intentions. There was less evidence relating to help-offering and help-seeking behaviors and mental health stigma. Sixteen behavior change techniques were identified across interventions that are discussed in relation to the wider men's health literature. The evidence on psychosocial interventions in male-dominated industries is limited due to methodological and conceptual issues. Recommendations for future research include standardized reporting of intervention descriptions, the use of theory to guide intervention development, and utilizing validated and reliable outcome measures.

Meta-Analysis
Poly-ADP ribose polymerase inhibitor (PARPi) is approved for HER2-negative advanced breast cancer with BRCA1/2 mutation. In recent years, many studies have explored the application of PARPi in neoadjuvant therapy, but failed to reach a unified conclusion. PubMed, Clinicaltrials.gov, Cochrane CENTRAL, Embase, and key oncological meetings for trials were searched for studies reporting neoadjuvant regimens with PARPi in HER2-negative breast cancer. Pathological complete response (pCR), residual cancer burden (RCB), breast-conservation surgery rate (BCSR), clinical response, and adverse events were extracted and pooled in a meta-analysis using the Mantel Haenszel random/fixed effects model. Subgroup analyses of pCR were conducted according to BRCA1/2 status, and hormone receptor (HR) status. Five studies (N = 1223) were included, the addition of PARPi to neoadjuvant regimens significantly increased pCR rates (HR 1.45, 95%CI 1.09-1.92, P = .01, I = 86%). In subgroup analysis, the addition of PARPi increased the pCR rate both in HR-positive (n = 383) and HR-negative (n = 431) subgroups, which showed a dominant effect of PARPi regardless of HR status (HR 2.07, 95%CI 1.33-3.23, P = .001, I = 0%; HR 1.85, 95%CI 1.39-2.26, P < .0001, I = 0%, respectively). However, when we performed a subgroup analysis based on the status of BRCA1/2, no further benefit for PARPi was found. Adverse reactions were generally tolerable. Other outcome indexes, including RCB, clinical response, BCSR, and PARPi did not show a clinical benefit. Regardless of BRCA1/2 status, PARPi in neoadjuvant therapy, can improve the pCR rate of HER2-negative breast cancer, especially in HR-positive patients. Thus, we should have performed larger randomized trials and provided a stronger evidence-based basis.

Age and Ageing Apr 2024Advancing health equity requires more contextualised evidence.
BACKGROUND
Advancing health equity requires more contextualised evidence.
OBJECTIVES
To synthesise published evidence using an existing framework on the origins of health disparities and determine care-related outcome disparities for residents of long-term care, comparing minoritised populations to the context-specific dominant population.
DESIGN
Systematic review.
SUBJECTS
Residents of 24-hour long-term care homes.
METHODS
The protocol was registered a priori with PROSPERO (CRD42021269489). Literature published between 1 January 2000 and 26 September 2021, was searched, including studies comparing baseline characteristics and outcomes in minoritised versus dominant populations. Dual screening, two-reviewer verification for extraction, and risk of bias assessments were conducted to ensure rigour. Studies were synthesized using a conceptual framework to contextualise evidence according to multi-level factors contributing to the development of care disparities.
RESULTS
Twenty-one of 34 included studies demonstrated disparities in care outcomes for minoritised groups compared to majority groups. Thirty-one studies observed differences in individual-level characteristics (e.g. age, education, underlying conditions) upon entry to homes, with several outcome disparities (e.g. restraint use, number of medications) present at baseline and remaining or worsening over time. Significant gaps in evidence were identified, particularly an absence of literature on provider information and evidence on the experience of intersecting minority identities that contribute to care-related outcome disparities in long-term care.
CONCLUSION
This review found differences in minoritised populations' care-related outcomes. The findings provide guidance for future health equity policy and research-supporting diverse and intersectional capacity building in long-term care.

Review
There is a growing body of evidence indicating a possible association between genetic variations and attention-deficit hyperactivity disorder (ADHD), although the results have been inconsistent. The objective of this study was to evaluate the correlation between the GRIN2A, GRIN2B and GRM7 gene polymorphisms and ADHD. A comprehensive meta-analysis and subgroup evaluation was conducted using a fixed-effects model to analyze the association between ADHD and GRIN2B (rs2284411), GRIN2A (rs2229193), and GRM7 (rs3792452) in six genetic models (dominant, recessive, overdominant, homozygous, heterozygous, and allele models). The meta-analysis comprised 8 studies. The overall analysis showed that the GRIN2B rs2284411 T allele and T carries were significantly associated with a decreased risk of ADHD (dominant model:TT + CT vs. CC: OR = 0.783; 95% CI: 0.627-0.980; = 0.032, allele model:T vs. C: OR = 0.795; 95% CI: 0.656-0.964; = 0.019), especially in the Korean subgroup (dominant model:TT + CT vs. CC: OR = 0.640; 95% CI: 0.442-0.928; = 0.019, overdominant model: CT vs. TT + CC: OR = 0.641; 95% CI: 0.438-0.938; = 0.022, allele model:T vs. C: OR = 0.712; 95% CI: 0.521-0.974; = 0.034 and heterozygous model: CT vs. CC: OR = 0.630; 95% CI: 0.429-0.925; = 0.018). However, no meaningful associations were found for rs2229193 and rs3792452. The results of the meta-analysis provide strong evidence that the rs2284411 T allele is significantly associated with reduced susceptibility to ADHD, particularly in the Korean population.

Review
It is well known that cortical damage may affect cognitive functions, whereas subcortical damage, especially brainstem stroke, would be far less likely to cause cognitive decline, resulting in this condition being overlooked. Few studies have focused on cognitive dysfunction after a pontine stroke. Here, we begin with describing our nine new case reports of in-depth neuropsychological findings from patients with pontine stroke. The dominant domain of cognitive dysfunction was commonly characterized by executive dysfunction, almost in line with previous studies. The severity was relatively mild. We give an overview of the available literature on cognitive decline following a pontine stroke. This is followed by discussions regarding the prognosis of the cognitive disabilities. Based on previous neuroimaging findings, we would like to get to the core of the neuropathology underlying the cognitive declines in the context of "diaschisis", a phenomenon of a broad range of brain dysfunctions remote from the local lesions. Specifically, our unique paper, with two modalities of neuroimaging techniques, may help us better understand the pathology. SPECT scans yield evidence of frontal and thalamic hyper-perfusion and cerebellar hypo-perfusion in patients with pontine stroke. Functional near-infrared spectroscopy, when focusing on the supplementary motor area (SMA) as one of the hyper-perfusion areas, exhibits that SMA responses may be subject to the severity of cognitive decline due to a pontine stroke and would also be related to the recovery. Finally, we posit that cognitive decline due to pontine stroke could be explained by the failure of hierarchical cognitive processing in the fronto-ponto-cerebellar-thalamic loop.

Review
Spinocerebellar ataxia type 3 (SCA3) is an autosomal dominant neurodegenerative disorder that gives rise to motor incoordination and progressive functional disabilities. Although pharmacological interventions have revealed promising prospects in the management of SCA3, adverse effects may become unbearable. The use of herbal remedies in traditional Chinese medicine (TCM) may serve as potential alternative medicines to delay the progression of the disease. This systematic review is intended to identify, appraise, and summarize the findings of studies pertaining to the therapeutic roles of herbal remedies in TCM targeting oxidative stress in the management of SCA3. A literature search for relevant articles published from 1 January 2013 to 30 June 2023 in three databases, namely PubMed, Web of Science, and Scopus, was carried out according to the procedures of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A total of ten preclinical studies met the inclusion criteria of the systematic review. We recognized the therapeutic potential of , , sp., , , , , , sp., , , , , and . We identified the types of preclinical models expressing polyglutamine (polyQ) expanded mutant protein (mATXN3), inducers of oxidative stress that mimic the SCA3 pathogenesis, and effective doses of the herbal remedies. The modes of action contributing to the attenuation of oxidative stress are activation of antioxidant pathways, ubiquitin-proteasome system and autophagy, regulation of apoptosis, proinflammatory signaling pathway and chaperones, regulation of mitochondrial function and biogenesis, and restoration of neurotransmission and synaptic plasticity. In conclusion, herbal remedies in TCM may possibly delay the progression of SCA3, therefore providing justification for clinical trials.

Review
BACKGROUND
Neurofibromatosis Type 1 is an autosomal dominant tumour-predisposition condition commonly diagnosed in childhood and fully penetrant by adulthood. Long-term monitoring through imaging is inconsistent and varies between high- and low-income countries. Implementation of a clinical practice guideline through a multidisciplinary clinic is instrumental to the care of adult Neurofibromatosis Type 1 patients. We aim to systematically review international diagnostic modalities and strategies to evaluate any association between a country's socioeconomic status and diagnostic modalities or strategies used for Neurofibromatosis Type 1 patients.
METHODS
We searched PubMed, Embase, Web of Science, and Cochrane. Relevant clinical information on the surveillance of adult Neurofibromatosis Type 1 patients worldwide was reviewed, extracted, and synthesised.
RESULTS
We identified 51 papers reporting on 7724 individuals. Multiple imaging modalities are actively employed in high-income and upper-middle-income countries for surveying adult Neurofibromatosis Type 1 patients. We did not find any relevant papers from low- and middle-income countries.
CONCLUSIONS
This systematic review suggests that there is robust data on diagnostic modalities for adult Neurofibromatosis Type 1 patients in high-income countries, but not for low- and middle-income countries. There is a lack of data on consolidated diagnostic strategies from both high- and low-income countries. Efforts should be made to publish data on usual clinical practice in low- and middle-income countries to develop clinical practice guidelines describing best medical practice to fit a local context.
