Association between vitamin D deficiency and otitis media with effusion in children: a systematic review and meta-analysis

Background Vitamin D plays a crucial role in the regulation of inflammation. However, its effect on the development of otitis media effusion (OME), an inflammatory disease of the middle ear without signs of infection, remains largely unknown. Objective To assess the association between vitamin D deficiency and OME in children by systematic review and meta-analysis of the literature. Methods Eligible studies retrieved from PubMed, ProQuest, Embase, Cochrane databases and trial registries published up to 30 October 2022 were included in this review. The risk of bias of the included articles was assessed with the JBI Critical Appraisal Checklist for observational studies. The certainty of evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation framework. Results We included eight studies (six case-control and two cross-sectional studies) involving 1,114 children, of which four studies were eligible for meta-analysis due to the significant clinical heterogeneity. We found that vitamin D deficiency (defined as vitamin D concentration of 20 ng/mL or less, i.e., ?50 nmol/L) might increase the odds of developing OME by 66.0% (n=514; OR 1.66; 95%CI 1.09 to 2.54; I2=20%), albeit with a very low certainty of evidence. Conclusion There is a very low quality of evidence indicating that vitamin D deficiency is associated with the development of OME in children. Further large, high-quality cohorts and adjusting for confounding factors are warranted to confirm our findings, ideally by exploring the dose-response relationship between vitamin D concentration and the development of OME.

Prognostic factors and outcomes of chronic limb threatening ischaemia in patients post kidney transplant: a systematic review

BackgroundKidney Transplantation (KT) is widely recognized as the optimal treatment for patients with End Stage Renal Disease (ESRD), improving not only life expectancy but also quality of life. Undetected peripheral arterial disease (PAD) in patients undergoing KT may lead to lower limb ischaemic ulceration and gangrene which is associated with an increased mortality rate. If undiagnosed and untreated this may lead to limb loss and graft failure. This review aims to evaluate the current evidence related to the prognosis of chronic limb-threatening ischemia (CLTI) in patients with a KT.MethodsWe conducted a systematic review of the literature in PubMed and MEDLINE, the Cochrane database of systematic reviews, Elsevier, Web of Science, and CINAHL using relevant search keywords to identify the prognosis and progression of CLTI in patients with a KT. Outcomes of interest were CLTI and progression rate in terms of haemodynamic measurement. This systematic review adhered to the guidelines set forth by the Cochrane Collaboration. The study design, population selection, and follow-up time frame were outlined in accordance with the PRISMA guidelines.ResultsStudies have shown a decline in the ankle-brachial index (ABI) post-KT, indicating vascular deterioration. Surgical interventions and amputations are more likely, particularly on the ipsilateral side of KT. The infrapopliteal artery is the most compromised in this cohort. A low ABI was found to be an independent predictor of graft failure, doubling the risk of mortality post-KT. Quality of evidence was observed to be low primarily due to confounding and selection bias.ConclusionsThe available evidence regarding the prognosis of CLTI in individuals with KT is limited to a small number of studies offering predominantly low-quality evidence and conflicting results pertaining to PAD and its progression into CLTI. Further research is required on CLTI prognosis and progression among KT recipients.

Comorbid health outcomes in patients with schizophrenia: an umbrella review of systematic reviews and meta-analyses.

There is no comprehensive umbrella review exploring the connection between schizophrenia and various health outcomes. Therefore, we aimed to systematically review existing meta-analyses about schizophrenia-associated comorbid health outcomes and validate the evidence levels. We performed an umbrella review of meta-analyses of observational studies to explore comorbid health outcomes in individuals with schizophrenia. Searches were conducted across PubMed/MEDLINE, EMBASE, ClinicalKey, and Google Scholar up to September 5, 2023, targeting meta-analyses of observational studies related to comorbid health outcomes in individuals with schizophrenia. We applied AMSTAR2 for data extraction and quality assessment, adhering to PRISMA guidelines. Evidence credibility was evaluated and categorized by evidence quality. Our protocol was registered with PROSPERO (CRD42024498833). Risk and protective factors were analyzed and presented through equivalent odds ratios (eRR). In this umbrella review, we analyzed 9 meta-analyses, including 88 original articles, covering 21 comorbid health outcomes with over 66 million participants across 19 countries. Patients with schizophrenia showed significant associations with multiple health outcomes, including asthma (eRR, 1.71 [95% CI, 1.05-2.78], class and quality of evidence [CE] = non-significant), chronic obstructive pulmonary disease (1.73 [1.25-2.37], CE = weak), pneumonia (2.63 [1.11-6.23], CE = weak), breast cancer of female patients (1.31 [1.04-1.65], CE = weak), cardiovascular disease (1.53 [1.12-2.11], CE = weak), stroke (1.71 [1.30-2.25], CE = weak), congestive heart failure (1.81 [1.21-2.69], CE = weak), sexual dysfunction (2.30 [1.75-3.04], CE = weak), fracture (1.63 [1.10-2.40], CE = weak), dementia (2.29 [1.19-4.39], CE = weak), and psoriasis (1.83 [1.18-2.83] CE = weak). Our study underscores the imperative for an integrated treatment approach to schizophrenia, highlighting its broad impact across respiratory, cardiovascular, sexual, neurological, and dermatological health domains. Given the predominantly non-significant to weak evidence levels, further studies are needed to reinforce our understanding.

Clinician-Reported Negative Symptom Scales: A Systematic Review of Measurement Properties.

Negative symptoms of schizophrenia are correlated with reduction of normal function and lower quality of life. They were newly defined by the NIMH-MATRICS Consensus in 2005, dividing the rating tools to assess them into first-generation scales, developed before the Consensus, and second-generation scales, based on the recently introduced definitions. The COnsensus-based Standards for the selection of health Measurement Instrument (COSMIN) guidelines for systematic reviews were used to evaluate the quality of psychometric data of the first-generation scales that cover the 5 negative symptom domains of the NIMHS Consensus: the Scale for the Assessment of Negative Symptoms (SANS), the High Royds Evaluation of Negativity Scale (HEN), and the Negative Symptom Assessment-16 (NSA-16). The search strategy resulted in the inclusion of a total of 13 articles, 7 for the SANS, 4 for the NSA-16, and 2 for the HEN. For the SANS and the NSA-16, the overall results of the scales' measurement properties are mostly insufficient or indeterminate. The quality of evidence for the HEN is poor, due to a small number of validation studies/included patients. After applying the COSMIN guidelines, we do not recommend the usage of these first-generation scales to rate negative symptoms. At the minimum they require further validation.

Acupuncture combined with opioid for treatment of lung cancer-related pain: A systematic review and meta-analysis.

Many individuals diagnosed with lung cancer suffer from tremendous pain, and it is crucial to implement more effective measures to assist these patients in alleviating their pain. The present study utilizes a meta-analysis to evaluate the safety and efficacy of acupuncture combined with opioids for treating lung cancer-related pain in patients. We have searched 8 electronic databases: The Cochrane Library, PubMed, Embase, Web of Science, China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang Database, and SinoMed. We included all randomized controlled trials of acupuncture combined with opioids for lung cancer-related pain in adults. We observed the main outcome indicators, including pain relief rates, numeric rating scale scores, and adverse events. Two researchers independently conducted literature screening, literature data extraction, and assessment of bias risk in the literature quality. Any disagreements were resolved through discussions between the 2 researchers or consultations with a third researcher. The risk of bias in the included studies was assessed using the revised risk of bias assessment tool. The overall quality of evidence for each outcome was evaluated using Grading of Recommendations, Assessment, Development and Evaluations. We retrieved 812 lung cancer patients from 11 trials. The study showed that compared to opioids alone, the combination of acupuncture and opioids significantly reduced numeric rating scale scores, increased pain relief rates, and decreased the occurrence of side effects. The current evidence indicates that combining acupuncture with opioid analgesics is superior to using opioid analgesics alone for managing lung cancer-related pain. Additionally, this combination therapy has fewer adverse reactions.

Effectiveness of Acupuncture in Improving Quality of Life for Patients with Advanced Cancer: A Systematic Review and Meta-Analysis.

To investigate the effect of acupuncture on advanced cancer patients by meta-analysis. Nine databases (the Cochrane Central Register of Controlled Trials, MEDLINE, Web of Science, Embase, China National Knowledge Infrastructure, the Cumulative Index to Nursing and Allied Health Literature, Chinese Biomedical Literature Database, China Science and Technology Journal Database, and WanFang Data) were searched for randomized controlled trials (RCTs) on acupuncture in advanced cancer patients published from inception to February 13, 2023 and updated to June 1, 2023. Primary outcomes were quality of life (QOL), while secondary outcomes were pain, fatigue, and adverse events (side effects). Data synthesis was performed using RevMan V.5.3 to calculate pooled effect sizes. RoB-2 was used for the risk of bias, and the quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. Totally 17 RCTs involving 1,178 participants were included, 15 of which were pooled for meta-analysis. Most studies demonstrated some concern for the overall risk of bias. The pooled data indicated that acupuncture was associated with improved QOL [mean difference (MD)=6.67, 95% confidence interval (CI): 5.09 to 8.26], pain (MD=-1.18, 95% CI -2.28 to -0.08), and adverse events (risk ratio=0.30, 95% CI: 0.26 to 0.57) compared with control groups. Fatigue outcome was not included. Heterogeneity was substantial, and GRADE evidence was very low for both QOL and pain. Acupuncture could benefit patients with advanced cancer and is considered safe compared with usual care. However, the evidence regarding QOL and pain outcomes requires further validation. It is crucial to encourage the development of high-quality studies to strengthen this evidence. (Registry No. CRD42023423539).

Challenges in assessing the effects of environmental governance systems on conservation outcomes.

Effective governance is crucial for the success of conservation projects aimed at protecting wildlife populations and supporting human well-being. However, few large-scale, comprehensive syntheses have been conducted on the effects of different environmental governance types on conservation outcomes (i.e., biological and ecological effectiveness or effects of conservation on human well-being), and clarity on the quantity and quality of evidence remains dispersed and ambiguous. We attempted a systematic map of the evidence on the effectiveness of different governance types to meet desired conservation outcomes in Africa, Asia, and Latin America. However, early in this effort, we observed a general lack of empirical research on the links between governance and conservation outcomes. To fill observed data gaps in the evidence base, we tried triangulating governance data from alternative sources (Protected Planet database) and pooling evidence from research conducted within the same conservation areas. Limited data were contained in the Protected Planet database, and governance types in conservation areas and landscapes were complex, making it difficult to use these approaches to assign governance types to conservation areas. To illustrate our observations from the failed systematic map attempt, we prepared a rapid evidence map that outlines a subset of the evidence base of articles linking governance types and governance principles with conservation outcomes. Only 3.2% (34 of 1067) of the articles we screened directly related conservation outcomes to governance type, and even fewer related governance principles to conservation outcomes. Based on our findings, we recommend improving the evidence base by supporting empirical research and increasing the availability and quality of governance data in freely accessible databases. These recommendations are critical for enhancing understanding of the role of governance in conservation projects and improving conservation outcomes.

Subcutaneous fast-acting insulin analogues ± long-acting insulin vs IV insulin infusion in DKA: updated meta-analysis of randomised trials.

Diabetic ketoacidosis (DKA) is often treated with intravenous regular insulin infusion (IVRII). Subcutaneous fast-acting insulin analogues (FAIAs); either alone or combined with subcutaneous long-acting insulin (LAI); might be useful to treat DKA. Our meta-analysis updated on their benefits and safety in DKA. We searched major electronic databases for randomised trials on subcutaneous FAIAs ± subcutaneous LAI vs IVRII in DKA. Primary outcomes were all-cause in-hospital mortality, time to resolution of DKA and hyperglycemia, in-hospital DKA recurrence and hospital readmission for DKA post-discharge. Secondary outcomes included resource utilisation and patient satisfaction. Safety outcomes were adverse events. Reviewers assessed risk of bias and quality of evidence using GRADE. We performed a priori subgroup and trial sequential analyses on primary outcomes. Seven trials enrolled 351 mainly adult patients (255/351) with mild to moderate DKA. No trials studied subcutaneous FAIA and subcutaneous LAI. Their risk of bias was high or unclear in several domains. No all-cause in-hospital mortality and DKA recurrence were reported. No trial investigated hospital readmission for DKA post-discharge. There was no difference in mean time to resolution of DKA (mean difference = -0.70, 95% CI -2.18 to 0.79 h, p = 0.36) or hyperglycemia [blood glucose < 250 mg/dL (13.9 mmol/L)] (mean difference = -0.17, 95% CI -1.10 to 0.76 h, p = 0.72) between subcutaneous FAIA and IVRII groups. There were largely no subgroup effects. Both groups had similar secondary outcomes. Hypoglycemia was the most common adverse event. Quality of evidence was low to very-low for all outcomes. The only possible trial sequential analysis for time to resolution of DKA was inconclusive. There was low- to very-low quality evidence that subcutaneous FAIA did not affect patient-centered outcomes in mainly adult patients with mild to moderate DKA compared to IVRII.

Efficacy of mechanical against manual method in cardiopulmonary resuscitation for out‑of‑hospital cardiac arrest: A meta‑analysis.

Out-of-hospital cardiac arrest (OHCA) remains a leading cause of mortality worldwide, with the efficacy of cardiopulmonary resuscitation (CPR) methods playing a crucial role in patient outcomes. The present study aimed to compare the effectiveness of mechanical and manual CPR in OHCA, focusing on three outcomes: Return of spontaneous circulation (ROSC), survival to admission and survival till discharge. A comprehensive meta-analysis was conducted, incorporating 39 studies for ROSC, 28 for survival to admission, and 30 for survival till discharge, totalling 144,430, 130,499 and 162,088 participants, respectively. The quality of evidence was evaluated using the GRADE approach, assessing risk of bias, inconsistency, indirectness, imprecision and publication bias. Statistical analysis included pooled odds ratios (ORs) with 95% confidence intervals (CIs) and sensitivity analyses. For ROSC, the pooled OR was 1.09 (95% CI: 0.92-1.29), demonstrating no significant difference between mechanical and manual CPR. Survival to admission favoured mechanical CPR with a pooled OR of 1.25 (95% CI: 1.09-1.43). No conclusive difference was found for survival till discharge, with a pooled OR of 0.79 (95% CI: 0.61-1.02). Substantial heterogeneity was observed across outcomes. Evidence of potential publication bias was noted, particularly in the survival to admission outcome. The overall quality of evidence was graded as very low, mainly due to high heterogeneity and indirectness of evidence. The study suggests that mechanical CPR may improve short-term outcomes such as survival to admission in patients with OHCA but does not demonstrate a significant long-term survival benefit over manual CPR.

Challenging antibiotic stewardship: antibiotic use in the management of acute pancreatitis without waiting for a CT scan or CRP marker.

Madam, Acute pancreatitis is an acute inflammation of the pancreas presenting as severe abdominal pain and elevated pancreatic enzymes. The global burden of Acute pancreatitis has increased by 3.07% per year, for the last 56 years.1 Gallstones, chronic alcohol, and hypertriglyceridemia are the main risk factors involved in the pathogenesis of Acute pancreatitis worldwide.2 However, in Pakistan gall stones impacting the common bile duct and hypertriglyceridemia are the main culprits. There has been an extensive debate regarding the use of prophylactic antibiotics and the outcome of acute pancreatitis. The cumulative evidence suggests that the prompt use of antibiotics, before obtaining serum markers, is not associated with a significant decrease in secondary pancreatic infection.3 Multiple studies have shown that the use of antibiotics, deviating from the recent guidelines, boosts antibiotic resistance and the risk of invasive fungal infections. A 2020 study conducted by Soulountsi has also rendered this practice unjustified.4 In studies supporting the use of prophylactic antibiotics in improving outcomes, the quality of evidence is low suggesting that the approach should be more tailored to individual patient conditions while adhering to the guidelines. Despite the sterile nature of the early stages of acute pancreatitis, some clinicians continue to opt for prophylactic use, however, it is strictly against the international consensus. Unfortunately, in Pakistan, there is a common practice of using antibiotics in acute pancreatitis within 72hrs, without waiting for the CT scan results and inflammatory markers screening. Antimicrobial resistance is an anticipated outcome of such practice. The prevalence of antimicrobial resistance to commonly prescribed antibiotics is already very high.5 Not weighing the risk-benefit ratio will not only contribute to increasing resistance but also predispose to avoidable and potentially fatal fungal infections. The appropriate approach to management of Acute pancreatitis should be based on a thorough knowledge of recent guidelines, carrying out proper investigations, and making an individualized plan for the patient based on clinical findings. This will not only minimize the burden of complications but also provide more room for improvements in the management of acute pancreatitis.

Oral Manifestations in Paraneoplastic Syndromes: ASystematic Review and Meta-Analysis.

This study examined the prevalence of oral signs and symptoms in paraneoplastic syndromes. A systematic search on oral paraneoplastic syndromes was conducted in MEDLINE/PubMed, Ovid, and Scopus databases from inception to April 1, 2024. Risk of bias was evaluated using the MURAD or Quality in Prognosis Studies tools, and a random-effects meta-analysis was performed. Evidence quality was rated using the GRADE approach. The study sample comprised 811 participants from 487 studies. Oral manifestations predominantly affected patients with paraneoplastic pemphigus, mucous membrane pemphigoid, and acanthosis nigricans. Palate is the most frequently affected site (18.2%; 95% confidence interval [CI] 14.7-21.9), while erosion was the most common lesion type (83.3%; 95% CI 72.2-92.0) associated with the underlying malignancy. The prevalence of death in people with paraneoplastic syndromes was 50.9% (95% CI 39.9-61.7), while the prevalence of remission after neoplasm treatment was 63.4% (95% CI 49.9-76.0). GRADE assessment revealed uniformly low to very low certainty for all outcomes studied. Further research is needed to understand the mechanisms behind these oral manifestations, which is crucial for earlier paraneoplastic syndrome diagnosis and optimal patient management. PROSPERO number: CRD42022328921.

Prognostic value of Ki67 in phyllodes tumor of the breast: A systematic review and meta‑analysis.

Numerous clinicopathological features have been examined as predictive factors for adverse outcomes in patients with phyllodes tumor (PT) of the breast, but there are still no definitive predictive markers to guide management, despite the persistent risk of recurrence, even in benign disease. Whether Ki67 has prognostic value in PT remains uncertain. Therefore, a systematic review and meta-analysis were performed to examine whether Ki67 is associated with adverse clinical outcomes, particularly recurrence, in patients with PT. The PubMed/MEDLINE, Web of Science, Scopus, Embase and Cochrane Library databases were searched from inception to July 2024. Study characteristics and outcomes (recurrence and overall survival) according to Ki67 status were extracted from each eligible study, and pooled log odds ratios (OR) with 95% CI were derived using a random-effects model. A total of five studies comprising 280 cases were eligible for inclusion. The adverse outcome rate for the Ki67high (Ki67 >10 or >11.2%) population was 28.7% (95% CI, 20.1-38.6%), while the adverse outcome rate for the Ki67low population was 9.4% (95% CI, 5.4-13.5%). Ki67high was associated with an increased odds of an adverse outcome [log OR, 1.26 (95% CI, 0.38-2.15; P=0.005)] compared with a Ki67low status. All five studies scored 8 points on the Newcastle-Ottawa Scale, equivalent to 'good' quality according to Agency for Healthcare Research and Quality standards, and no significant publication bias was noted. This was the first meta-analysis of the predictive value of Ki67 in PT of the breast. A relatively high Ki67 index (>10%) is associated with recurrence. It is timely to re-evaluate the prognostic value of Ki67 in large retrospective cohorts with long follow-up to firmly establish whether it could contribute to identifying patients at risk of recurrence, particularly those with histologically benign disease. Doing so could impact clinical practice by refining follow-up recommendations based on quality evidence.

Prior probability biases perceptual choices by modulating the accumulation rate, rather than the baseline, of decision evidence

Abstract The prior probability of an upcoming stimulus has been shown to influence the formation of perceptual decisions. Computationally these effects have typically been attributed to changes in the starting point (i.e. baseline) of evidence accumulation in sequential sampling models. More recently, it has also been proposed that prior probability might additionally lead to changes in the rate of evidence accumulation. Here, we introduce a neurally-informed behavioural modelling approach to understand whether prior probability influences the starting point, the rate of evidence accumulation or both. To this end, we employ a well-established visual object categorization task for which two neural components underpinning participants’ choices have been characterised using single-trial analysis of the electroencephalogram. These components are reliable measures of trial-by-trial variability in the quality of the relevant decision evidence, which we use to constrain the estimation of a hierarchical drift diffusion model of perceptual choice. We find that, unlike previous computational accounts, constraining the model with the endogenous variability in the relevant decision evidence, results in prior probability effects being explained primarily by changes in the rate of evidence accumulation rather than changes in the starting point or a combination of both. Ultimately, our neurally-informed modelling approach helps disambiguate the mechanistic effect of prior probability on perceptual decision formation, suggesting that prior probability biases primarily the interpretation of sensory evidence towards the most likely stimulus.

Evaluation and treatment of rhinosinusitis with primary antibody deficiency in children: Evidence-based review with recommendations.

There is clear evidence that prevalence of primary antibody deficiency (PAD) is higher in children with chronic rhinosinusitis (CRS) than in the general population. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on rhinosinusitis with PAD, summarize the existing evidence, and provide recommendations on the evaluation and management of rhinosinusitis in children with PAD. The PubMed, Embase, and Cochrane databases were systematically reviewed from inception through December 2023. Studies on the evaluation and management of rhinosinusitis in PAD patients were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on the evaluation and management principles for PAD were generated. A total of 50 studies were included in this evidence-based review. These studies were evaluated on the incidence of PAD in rhinosinusitis patients, the incidence of rhinosinusitis in PAD patients, and on the different treatment modalities used and their outcome. The aggregate quality of evidence varied across the reviewed domains. Based on the currently available evidence, the incidence of PAD in children with recalcitrant CRS can be significantly elevated. Despite the presence of multiple studies addressing rhinosinusitis and PAD, the level of evidence supporting different treatment options continues to be lacking. Optimal management requires a multidisciplinary approach through collaboration with clinical immunology. There is need for higher level studies that compare different treatments in children with PAD and rhinosinusitis.

The impact of COVID-19 infection on idiopathic pulmonary fibrosis mortality: a systematic review and meta-analysis.

COVID-19 has a negative impact on the survival of respiratory patients, especially those with interstitial lung disease. This review aims to better understand the effect of COVID-19 on patients with idiopathic pulmonary fibrosis (IPF). A systematic search of MEDLINE, PubMed, Embase, and Scopus performed from December 2019 up to July 2024 identified relevant studies. Eligibility criteria included English language, sample size ≥10 patients, COVID-19 infection and outcome measures. Two independent reviewers assessed studies using the Newcastle-Ottawa Scale for bias and extracted data. Meta-analysis employed a random-effects model, and the Grading of Recommendations Assessment, Development and Evaluation assessed evidence quality. Outcomes considered were hospitalization, intensive care unit admission, and mortality. Of the 1541 initially identified articles, 6 high-quality studies were included. Meta-analysis revealed a 34% mortality rate [95% confidence interval (CI): 21-48%], 36% hospitalization rate (95% CI: 10-75%), and 31% ICU admission rate (95% CI: 7-71%) among IPF patients with COVID-19. The certainty of evidence was low or very low due to publication bias and heterogeneity. This study underscores the elevated risk of hospitalization and death in IPF patients with COVID-19, emphasizing the vulnerability of this population. Prompt and tailored care is crucial to mitigate the impact of COVID-19 on IPF patients, necessitating proactive measures, vaccination, and comprehensive management.

Elevated Blood Pressure and Culprit Aneurysm Rebleeding During the Unsecured Period of Aneurysmal Subarachnoid Hemorrhage: A Systematic Review.

In aneurysmal subarachnoid hemorrhage, rebleeding prior to securing the culprit aneurysm leads to significant morbidity and mortality. Elevated blood pressure has been identified as a possible risk factor. In this systematic review, we evaluated the association between elevated blood pressure and aneurysm rebleeding during the unsecured period. We searched MEDLINE, Embase + Embase Classic, and CENTRAL, from inception to March 8th, 2024. We included studies of adults with aneurysmal subarachnoid hemorrhage reporting at least one blood pressure measurement during the unsecured period and a measure of association with rebleeding. Results were stratified by blood pressure thresholds, effect measure, and adjustment for confounding. Separate meta-analyses were performed for each of these groups. Our search identified 5,209 citations. After screening, 15 studies were included in our review. All studies were observational in design and at moderate or high risk of bias. Meta-analysis of the unadjusted results produced mixed findings across the systolic blood pressure (SBP) thresholds: SBP > 140mmHg, unadjusted odds ratio (uOR) 1.03 (95% confidence interval [CI] 0.55-1.93; I2 = 66%); SBP > 160mmHg, uOR 3.35 (95% CI 1.44-7.81; I2 = 83%); SBP > 180mmHg, uOR 1.52 (95% CI 0.40-5.81; I2 = 89%); and SBP > 200mm Hg, uOR 7.99 (95% CI 3.60-17.72; I2 = 0%). Meta-analysis of adjusted results was only possible at an SBP > 160mmHg; adjusted hazard ratio 1.13 (95% CI 0.98-1.31; I2 = 0%). The overall quality of evidence as assessed by the Grading of Recommendations, Assessment, Development, and Evaluations tool was rated as very low. Based on very low quality evidence, our systematic review failed to determine whether there is an association between elevated blood pressure during the unsecured period and increased risk of culprit aneurysm rebleeding.

Interpretation of WFAS Clinical practice guideline on acupuncture and moxibustion: smoking cessation

The paper interprets the formulation, main content and characteristics of Clinical practice guideline on acupuncture and moxibustion: smoking cessation issued by World Federation of Acupuncture Societies (WFAS 007.2-2023, short for Guideline). The Guideline focuses on the clinical value of acupuncture regimen for smoking cessation and its abstinence rate, and attaches the importance to the actual needs of patients, the counseling and management of smoking cessation. The Guideline is characterized by its international orientation, the integration of Chinese and Western medicine, and the advantages of acupuncture for smoking cessation. It is formulated concisely in content and highlights the clinical practicability. During the guideline development for smoking cessation in future, the consideration should be paid on improving the evidence quality of acupuncture, preserving the characteristics of acupuncture and emphasizing patients' demand, the counseling and management of smoking cessation, as well as the scenarios of implementation so as to improve the quality and applicability of the guidelines.

A systematic review of the effect of sandplay therapy on social communication deficits in children with autism spectrum disorder.

To explore the efficacy of sandplay therapy in intervening social communication deficits in children with autism spectrum disorders (ASD), and whether this efficacy is influenced by the age of the children and the dosage of sandplay therapy intervention. Following the PICOS principle, randomized controlled trials (RCTs) related to sandplay therapy for social communication deficits in ASD children were retrieved from seven databases: PubMed, WOS, The Cochrane Library, Embase, CNKI, Wanfang, and VIP, from the inception of each database to November 10, 2023. Two experimenters independently conducted study screening and excluded studies with concomitant diseases, incomplete data, unextractable data, and non-randomized controlled trials. The PEDro scale was used for methodological quality assessment, and the GRADEprofiler method was employed to evaluate the quality of evidence. Stata17 software was used for meta-analysis, subgroup analysis, sensitivity analysis, and publication bias testing. The standardized mean difference (SMD) and 95% confidence interval (CI) were used as the effect statistics. A total of 12 RCTs (791 cases) were included. Sandplay therapy had a positive impact on the social communication deficits of ASD children [SMD = -1.42, 95%CI (-1.79, -1.04), P < 0.001]. Subgroup analysis revealed that sandplay therapy administered during the early school age (449 cases, SMD = -1.44, P < 0.05), for a duration of 22-28 weeks (208 cases, SMD = 1.69, P < 0.05), and with a frequency of once per week (218 cases, SMD = -1.67, P < 0.05) was most effective in improving on social communication deficits of ASD children. The quality of evidence in this study was rated as high, with good methodological quality, including 12 studies with better quality and no detection of bias risk. The study had high heterogeneity, which was attributed to the measurement tools and intervention duration through subgroup analysis, with no inconsistency found. Additionally, no downgrade factors related to imprecision, publication bias, or indirectness were identified. In conclusion, sandplay therapy is an effective measure to improve social communication deficits in children with ASD, and current evidence recommends early intervention using an individual sandplay therapy or integrated sandplay therapy intervention program once a week for 22-28 weeks, which can serve as evidence-based clinical guidance. www.crd.york.ac.uk, identifier (CRD420234821750).

The role of mind-body interventions in traumatised refugees’ primary care: A qualitative exploration of professionals’ experiences in a dedicated programme in Geneva

Post-traumatic physical and psychological symptoms are pervasive among refugees. Primary care staff face numerous challenges and often seek innovative ways of addressing their refugee patients’ physical and mental health needs. A nascent body of literature suggests that mind-body interventions (MBIs11Mind-body interventions) have a positive effect on post-traumatic symptoms in this population. But the quality of evidence is still poor, and little is known about the role MBI could play in the primary care of refugees. Following the implementation of two different kinds of MBI in a dedicated primary care unit, this study aimed to explore staff members’ perceptions and prescribing habits for MBI. Given the paucity of information about this topic, we used a qualitative design combining ethnography and discourse analysis providing in-depth insight into professionals’ experiences of MBI. Data collected over five-months of non-participative observation and the transcription of twelve interviews were analysed following the Interpretative Phenomenological Analysis method (IPA) yielding four main results: (1) Generally poor initial understanding of MBI; (2) A variety of conditions and situations where MBIs appeared acceptable and helpful; (3) A persistent lack of experience and knowledge about the indications for MBI, hindering prescription; (4) The importance of articulating MBIs with mental health services. These results, in the light of the existing literature, suggest that stronger evidence for MBI efficacy for refugees is required, a key to improving professionals’ understanding of MBI, providing them with explicit prescription criteria, and encouraging stakeholders to implement these innovative interventions.
