Optimal Duration of Antibiotic Therapy for Primary Osteomyelitis Discitis: A Systematic Review and Network Meta-Analysis

STUDY DESIGN

Systematic review and network meta-analysis.

OBJECTIVE

This study aimed to systematically review the literature on the management of primary osteomyelitis discitis and perform a network meta-analysis comparing the efficacy of different antibiotic treatment durations.

BACKGROUND

Primary osteomyelitis discitis is a challenging condition with varying management strategies.

MATERIALS AND METHODS

A comprehensive literature search was conducted. Studies reporting outcomes for the treatment of primary osteomyelitis discitis were included. A random-effect network meta-analysis was performed comparing antibiotic treatment durations of <4 weeks, 4 to 8 weeks, 8 to 12 weeks, and 12 to 16 weeks. The surface under the cumulative ranking curve (SUCRA) was used to rank treatment effectiveness.

RESULTS

Sixty-three articles with 4233 patients were included. Staphylococcus aureus was the most common causative agent (57.6%). The 4 to 8-week antibiotic duration ranked highest across fixed-effect and random-effect models (SUCRA: 0.8207 and 0.8343). The 12 to 16-week duration ranked highest in the fixed-effect model (SUCRA: 0.8460) but dropped substantially in the random-effect model (SUCRA: 0.3067). The <4-week duration showed mixed results. The 8 to 12-week duration consistently ranked lowest. No statistically significant differences were found between durations for symptomatic relief.

CONCLUSION

Antibiotic therapy for 4 to 8 weeks may provide the optimal balance of efficacy and treatment duration for most patients with primary osteomyelitis discitis. However, treatment should be individualized based on clinical response. Further prospective studies are needed to clarify optimal management strategies for this complex condition.

Vitamin D Deficiency and Clinical Outcomes in Critically Ill Pediatric Patients: A Systematic Review and Meta-Analysis

Context

Vitamin D deficiency (VDD) is common in paediatric populations, and its relationship with critical care outcomes warrants further investigation.

Objective

The aim is to examine the association between VDD and clinical outcomes in children admitted to the Pediatric Intensive Care Unit (PICU).

Methods

This systematic review and meta-analysis investigated the impact of VDD on clinical outcomes in PICU patients. A comprehensive search of Embase, Web of Science, PubMed, and Cochrane databases was conducted. Our primary outcomes were mortality and sepsis incidence, while secondary outcomes included length of stay (LOS), need for inotropic support, and need for and duration of mechanical ventilation. Eligible studies included infants and children aged 1 month to 18 years admitted to the PICU, with baseline 25-hydroxyvitamin D levels measured on admission. Two independent reviewers screened studies, extracted data, and assessed quality. Pooled estimates were obtained using a random-effects model.

Results

Out of 2298 screened studies, 27 met the inclusion criteria, comprising 4682 patients. VDD was defined as 25-hydroxyvitamin D levels <20 ng/mL and <30 ng/mL in 22 and 5 studies, respectively. VDD was associated with increased mortality (odds ratio [OR] 2.05, 95% CI 1.21-3.48) and a greater need for inotropic support (OR 2.02, 95% CI 1.43-2.85) than children with vitamin D sufficiency (VDS). No differences were observed between VDD and VDS groups in terms of sepsis incidence postadmission, LOS, or the need for and duration of mechanical ventilation.

Conclusion

VDD in critically ill pediatric patients was associated with increased mortality and higher need for inotropic support. Further research is warranted to evaluate the potential benefits of vitamin D supplementation in this high-risk population.

Speaking of yourself: A meta-analysis of 80 years of research on pronoun use in schizophrenia

People with schizophrenia experience significant language disturbances that profoundly affect their everyday social interactions. Given its relevance to the referential function of language, aberrations in pronoun use are of particular interest in the study of schizophrenia. This systematic review and meta-analysis, adhering to PRISMA guidelines, examines the frequency of pronoun use in schizophrenia. PubMed, PsycINFO, Scopus, Google Scholar, and Web of Science were searched up to May 1, 2024. All studies analyzing pronoun frequency in various spoken language contexts in schizophrenia were included. Bias was assessed using a modified Newcastle-Ottawa Scale. A Bayesian meta-analysis with model averaging estimated effect sizes and moderating factors. 13 studies with n = 917 unique participants and 13 case-control contrasts were included. 37.9 % of patient samples were women, with a weighted mean (SD) age of 34.45 (9.72) years. 53.85 % of the studies were in languages other than English. We report a medium-sized effect for first-person pronoun impairment in schizophrenia (model-averaged d = 0.89, 95 % CrI (0.44, 1.33)). There was significant heterogeneity moderated by age. Evidence for publication bias was weak, with a strong support for first-person pronoun impairment after accounting for bias and heterogeneity. There was a small reduction of inter-individual variability in first-person pronoun use in patients compared to healthy controls (lnCVR = -0.12, 95 % CrI [-0.35, -0.13]). While all pronoun use was also high in patients, this was not robust due to heterogeneity and publication bias. Individuals with schizophrenia excessively use first-person pronouns. This may be a marker of a disturbed sense of self in this illness.

Low Socioeconomic Status Is Associated With Worse Patient-Reported Outcomes Following Total Joint Arthroplasty: A Systematic Review

BACKGROUND

Socioeconomic status (SES)-an individual or group's social standing or class, as measured by education, income, and occupation-has been associated with poor surgical outcomes in orthopaedics. Total knee arthroplasty and total hip arthroplasty (THA) are the most commonly investigated orthopaedic surgeries regarding SES and patient-reported outcome measures (PROMs), yet the results are contradictory. The aim of this systematic review was to assess the impact of SES on PROMs following total joint arthroplasty (TJA).

METHODS

We performed a literature search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines utilizing MEDLINE (Ovid), EMBASE (Ovid), and Cochrane Library from database inception (1971, 1974, and 1996, respectively) to August 2, 2023, to identify studies investigating SES and PROMs in adults undergoing primary elective TJA. Studies were included if they evaluated one of three SES variables (income, education, or employment status) and reported at least one-year scores using a validated PROM. There were two reviewers who independently screened studies and extracted data.

RESULTS

There were 16 studies included in this systematic review. A total of 55,875 arthroplasties, including 24,055 total knee arthroplasties and 31,820 THAs, were analyzed. Of the studies, eight evaluated income, 15 evaluated education, and two evaluated employment status. The majority of studies investigating income found a statistically significant association between lower income and worse postoperative PROMs. There were ten studies, involving 90% of all patients from the included education studies, which found a statistically significant association between education and postoperative PROMs. There were two studies that found unemployed THA patients had lower improvements in PROMs compared to employed and retired patients.

CONCLUSIONS

Our systematic review found several significant associations between income, education, employment, and PROMs after TJA. Providers should pay special attention to lower-income, less educated, and unemployed patients. These patients may benefit from targeted interventions to achieve substantial clinical benefit after TJA.

The safety profile of subthalamic nucleus and globus pallidus internus deep brain stimulation for Parkinson's diseases: A systematic review of perioperative complications and psychological impacts

BACKGROUND

Despite its widespread use and acceptance, there is still a significant need for a comprehensive understanding of the safety profile of deep brain stimulation (DBS) for Parkinson's Disease. This study investigates the surgical and psychological complications associated with DBS surgery for movement disorders, aiming to quantify patient risk and promote broader acceptance of the procedure.

METHODS

This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. It focused on a substantial population of 3,599 patients from various studies who underwent DBS between 2000 and 2024. A thorough literature search was carried out to identify studies on the safety profile of DBS in Parkinson's Disease (PD) across multiple electronic databases. Two reviewers extracted data and independently assessed the risk of bias, and all authors resolved any discrepancies collectively.

RESULTS

This review identified 17,453 studies, but only 26 were thoroughly reviewed after fulfilling all inclusion criteria. DBS showed both therapeutic benefits and significant risks, with complications including neurological deficits, infections, cognitive and psychiatric symptoms, surgical or device-related issues, motor dysfunction, and mortality.

CONCLUSION

Overall, the findings support the cognitive safety of DBS, revealing limited adverse effects on cognitive functions. This review confirms therapeutic advantages and significant risks during and after surgery, including intraoperative and long-term adverse events. Additional reviews are required to evaluate the long-term impact of these complications, thereby enhancing patient safety and quality of life.

Comparative analysis of bacterial abundance and diversity in tumour tissue of oral squamous cell carcinoma and non-tumour tissue: insights from a systematic review of 16S ribosomal RNA sequencing

BACKGROUND

As per the recent research findings, there is a significant difference between the bacteriome of normal tissue (NT) and tumor tissues (TT) of oral squamous cell carcinoma (OSCC). Identifying this distinct bacteriome is crucial for understanding their potential contribution to oral carcinogenesis. This systematic review (SR) aims to identify exclusive and relative bacterial abundance and bacterial diversity in TT and NT.

METHODOLOGY

The review was conducted following the PRISMA guidelines. PUBMED and SCOPUS databases were searched for studies in English published till 31st August 2024. The inclusion criteria focused on identifying bacteriome in NT versus TT at either species,/genus, and/or phylum level through 16 s ribosomal RNA sequencing. Quality assessment was performed using an eleven-parameter tool combining the Newcastle-Ottawa Scale and customized criteria.

RESULT

Evaluating the selected 13 articles, we have identified the exclusive and relative abundance of bacteriome in TT and NT at phylum, genus, and species levels. Three phyla such as Chloroflexota, Deinococcus-Thermus, and Mycoplasmatota, are found exclusively in TT. Seven genus such as Eubacterium, Campylobacter, Aeromonas, Oceanivigra, Rheinheimera, Weissella, and Catonella are exclusively found in TT. Ten species such as Micrococcus luteus, Prevotella melaninogenica, Exiguobacterium oxidotolerans, Fusobacterium naviforme, Staphylococcus aureus, Veillonella parvula, Parvimonas sp oral taxon 110, Eubacterium II G1 infirmum, Eubacterium XI G3 Brachy, Weissella viridescens are found in TT. Six genus such as Capnocytophaga, Selenomonas, Leptothrix, Desulfovibrio, Desulfoplanes, Pelospora are found exclusively in NT. Eleven species, such as Streptococcus sp. Oral taxon 071,Selenomonas sputigena, Treponema pedis, Acholeplasmatales bacterium, Capnocytophaga haemolytica, Eubacterium sp., Syntrophomonadaceae genomosp.,Treponema putidum, Mitsuokella sp., Actinomyces sp. Oral taxon 848 str. F0332, p- 2534 - 18B5-gut-group are found in NT. Seven common genera within which different species are identified in TT and NT, suggesting differences in bacterial behaviour and characteristics within the same genus. A total of 12 phyla, 35 genera, and 54 species were found to be relatively more abundant in TT compared to NT. Conversely, 7 phyla, 32 genera, and 45 species were relatively more abundant in NT than in TT. Considerable variations in diversity metrics were found between TT and NT.

CONCLUSION

This systematic review is the first to identify a distinct bacteriome exclusive to OSCC tumour tissue compared to normal tissue using 16S ribosomal RNA sequencing. This pioneering work lays the foundation for future studies on the oral microbiome as a potential diagnostic or therapeutic target in oral cancer management. It emphasizes the importance of exploring species-level differences for a deeper understanding of their roles in OSCC.

Role of circulating tumor DNA and cell-free DNA biomarkers in diagnosis and prognosis of oral cancer - a systematic review

BACKGROUND

Oral squamous cell carcinoma is the most common malignant neoplasm of the oral cavity, contributing significantly to cancer-related mortality worldwide. Circulating tumor DNA could be a promising biomarker for the early diagnosis and prognosis of oral cancer.

OBJECTIVE

The aim of this systematic review was to consolidate the existing literature on the role of circulating tumor DNA (ctDNA) and cell-free DNA (cfDNA) in the diagnosis and prognosis of oral cancer.

METHODOLOGY

The review protocol followed PRISMA guidelines. A systematic search was conducted across PubMed, Web of Science, Google Scholar and SCOPUS. Only English-language studies were included, while narrative reviews, HPV-positive OSCC, systematic reviews, meta-analyses, abstracts, and letters to the editor were excluded. Data were extracted on study design, country, sample size, participant characteristics, assessment methods, type of oral cancer and measured outcomes. Risk of bias was evaluated using Newcastle-Ottawa Scale (NOS).

RESULTS

A total of 3,155 records were identified, out of which 17 studies met the inclusion criteria. These comprised eleven cohort studies, one was a case series, two were descriptive studies, and three were case-control studies. The studies primarily addressed oral squamous cell carcinoma (OSCC) and head and neck squamous cell carcinoma (HNSCC). Findings revealed that elevated cfDNA levels are associated with poor prognosis, lymph node metastasis, larger tumor size and advanced disease stages. ctDNA acts as a predictive tool for monitoring cancer progression, treatment response, recurrence risk, and overall survival. Among 12 studies evaluated using NOS, 8 were of good quality, while 4 were fair quality.

CONCLUSION

ctDNA and cfDNA exhibit promising prognostic and diagnostic potential for OSCC and HNSCC. Elevated cfDNA levels correlate with poor prognosis, while ctDNA shows potential for monitoring cancer progression and treatment response.

Prognostic and associative significance of malnutrition in sarcopenia: a systematic review and meta-analysis

BACKGROUND

Malnutrition is a common phenomenon, particularly in those at an increased risk of muscle mass and function losses. In this systematic review and meta-analysis, we aimed to explore the association of malnutrition with sarcopenia in middle-aged and older adults and the prognostic association of malnutrition and sarcopenia vs. sarcopenia alone on all-cause mortality.

METHODS

PubMed, Scopus, Web of Science, and Cochrane Library were searched from inception until January 2024. A meta-analysis using a random-effect model was employed, utilizing the Mini Nutritional Assessment (MNA) malnutrition tool as a continuous and categorical variable. The study protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO: CRD42024501521).

RESULTS

Malnutrition was significantly associated with a greater risk of sarcopenia (continuous: k = 12, odds ratio (OR): 1.38, 95% CI 1.18 - 1.61, I2 = 94.8%, P < 0.01; categorical: k = 37, OR: 2.99, 95% CI 2.26 - 3.96, I2 = 78.3%, P < 0.01). Sarcopenia and malnutrition was associated with a higher risk of mortality compared to sarcopenia alone (k = 5, hazard ratio (HR): 4.04, 95% CI 1.36 - 11.94, I2 = 92.8%, P < 0.01). Meta-regression showed age, sex, and number of adjustments did not explain heterogeneity among studies. The included studies had moderate risk of bias.

CONCLUSIONS

Malnutrition is associated with a higher odds of sarcopenia and their combined presence is a better predictor of all-cause mortality compared to sarcopenia alone, further highlighting the importance of applying interventions to counteract these two closely related phenomena.

Prevalence and Diversity of Gastrointestinal Nematodes in Small Ruminants in Iran: a Systematic Review and Meta-analysis

PURPOSE

Gastrointestinal nematodiasis is a significant challenge in small ruminant breeding. The present systematic review and meta-analysis shed light on the frequency and distribution of the infection in a nationwide perspective.

METHODS

The review used 34 animal level datasets retrieved from 26 published articles and the pooled estimates were calculated using a random-effects model analysis.

RESULTS

Altogether, 9690 small ruminants were examined post-mortem or by coproscopy, among which 4193 animals were infected with GINs, showing a weighted prevalence of 55% (95% CI 44-66%). Reports were documented in 12 provinces with the highest frequency in Eastern Azerbaijan (77%), Kermanshah (76.04%), and Guilan (71.62%). Moreover, the highest prevalences were estimated among goats [61% (95% CI 48-74%)] and in coproscopy [67% (95% CI 57-78%)]. The reported GINs represented 15 genera, including Haemonchus contortus, Marshallagia marshalli, Trichuris spp., Trichostrongylus spp., Ostertaginae species, Gongylonema pulchrum, Nematodirus spp., Parabronema skrjabini, Skrjabinema ovis, Chabertia ovina, Cooperia punctata, Camelostrongylus mentulatus, Bunostomum trigonocephalum, and Oesophagostomum venulosum. The most isolated nematode species in sheep and goats belonged to H. contortus [7.44% (95% CI 6.78-8.13%] and Trichuris spp. [18.42% (95% CI 16.54-20.41%)].

CONCLUSION

A considerable parasitic prevalence was calculated in small ruminants in Iran, demanding strategic interventions for better control the GIN infections and decrease the worms burden and their consequences in sheep and goat population in Iran.

How do we define normal bowel frequency from newborn to teens?: A Bayesian meta-analysis

OBJECTIVES

Defecation disorders are a common pediatric problem and bowel frequency is crucial in identifying them. The aim of this analysis is to define normal bowel frequencies in healthy children ranging from newborns to adolescents.

METHODS

A literature search was conducted using MEDLINE, SCOPUS, EMBASE, Cochrane Library, and Web of Science from their inception to February 2024, aiming to identify studies reporting bowel habits of healthy children (0-18 years). A Bayesian distribution modeling approach was adopted to pool the mean frequency of bowel opening using inverse-variance weighing. A subgroup analysis and a meta-regression were performed with Bayesian generalized additive mixed distributional models. The methodological quality of the articles was evaluated using the Newcastle-Ottawa Scale modified for cross-sectional studies.

RESULTS

Seventeen studies were included in the analysis, including 22,698 children aged from 0 to 18 years. The subgroup meta-analysis showed mean bowel frequencies for newborns, 1-6 months, 6-12 months, 1-2 years, 2-5 years, and over 5 years are 3.24 (95% credible interval [CrI]: 2.83-3.63), 1.99 (95% CrI: 1.77-2.19), 1.66 (95% CrI: 1.45-1.88), 1.53 (95% CrI: 1.37-1.7), 1.15 (95% CrI: 0.99-1.31), and 1.02 (95% CrI 0.88-1.18), respectively. Between studies, heterogeneity demonstrated a near-normal distribution with a mean of 0.16 and a 95% CrI of 0.04-0.28. The variance of the distribution of mean bowel frequency reduced with age.

DISCUSSION

In this Bayesian meta-analysis, we found that younger children have a higher bowel frequency. The reported bowel frequencies for each age group could serve as normal values in clinical practice to differentiate health and disease.

Single-visit endodontic treatment under general anaesthesia in adult and adolescent patients with special needs: a systematic review

To improve dental care for individuals with special needs, it is crucial to understand the effectiveness of endodontic treatments under general anaesthesia. This systematic review explores the feasibility, prognostic factors, and outcomes of root canal treatment and pulpotomy performed under general anaesthesia in adult and adolescent patients with special needs. A comprehensive search of Cochrane Library and MEDLINE databases was conducted until July 2024. The quality of evidence was assessed using the Newcastle-Ottawa scale (NOS). Among the 637 initially identified studies, 5 met the inclusion criteria. Treatment outcomes, radiographic findings, and clinical survival rates were evaluated. Root canal treatment success rates ranged from 81.5 to 90% over a minimum observation period of 12 months. Survival rates varied from 87.7% (9 year cumulative survival rate) to 89.8% (5 year survival rate). One study showed a lower failure risk in endodontic treatment under general anaesthesia compared to local anaesthesia. Another study found no significant difference in root canal treatment quality between general and local anaesthesia. Influencing factors identified by multivariate regression analyses included soft diet, periodontal status, oral hygiene status, pulp vitality, and length of root canal filling. Limited evidence suggests that endodontic treatment under general anaesthesia is feasible and can yield favourable outcomes in patients with special needs. However, the scarcity of studies and concerns about publication bias and methodological limitations emphasize the need for further research.

Off-pump versus on-pump coronary artery bypass grafting in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis

INTRODUCTION

Off-pump coronary artery bypass graft surgery (OPCAB) has been suggested as superior to on-pump coronary artery bypass graft surgery (ONCAB) in certain high-risk subgroups, but its benefit in patients with chronic obstructive pulmonary disease (COPD) remains controversial. This meta-analysis aimed to evaluate OPCAB versus ONCAB outcomes in COPD patients.

METHODS

We followed PRISMA guidelines and searched PubMed, Embase, and the Cochrane Library in August 2024 for studies comparing OPCAB and ONCAB in COPD patients. Statistical analysis was conducted using Review Manager 5.4.1 and Rstudio with a fixed or random effects model.

RESULTS

Six studies with a total of 1,687 patients were included, of which 1,062 (62.95%) underwent OPCAB. The mean patient age was 63.6 years. OPCAB did not significantly affect all-cause mortality compared to ONCAB (OR 1.14; 95% CI 0.65-1.99). There were no significant differences in reintubation (OR 0.81; 95% CI 0.53-1.23), prolonged ventilation (OR 0.54; 95% CI 0.24-1.22), post-operative atrial fibrillation (OR 0.90; 95% CI 0.70-1.15), or ARDS (OR 0.43; 95% CI 0.14-1.33). However, ventilation time was significantly shorter in the OPCAB group (MD - 5.30 h; 95% CI - 7.22 to - 3.38).

CONCLUSION

OPCAB is associated with reduced ventilation time in COPD patients though it shows no significant difference in all-cause mortality or other post-operative complications compared to ONCAB.

The Efficacy and Safety of Botulinum Neurotoxin Type A in Treating Chronic Low Back Pain: A Systematic Review, Meta-Analysis, Trial Sequential Analysis, and Meta-Regression

BACKGROUND

Chronic low back pain (CLBP) is a leading cause of disability. Botulinum neurotoxin type A (BoNT-A) has strong anti-spasmodic and analgesic effects, suggesting that its local muscular injection can reduce CLBP compared to other therapies. In this systematic review and meta-analysis, we investigated the efficacy and safety of BoNT-A on patients with CLBP.

METHODS

We searched PubMed, Scopus, Cochrane, and Web of Science databases for studies comparing BoNT-A to other therapies in terms of functional improvement and pain improvement as measured by visual analog scale (VAS) and clinically significant improvement in pain (50% or greater reduction in VAS score). We employed trial sequential analysis (TSA) to confirm the findings. The GRADE approach was employed to assess the overall quality of the evidence.

RESULTS

The search yielded nine studies, seven randomised clinical trials (RCTs), and two prospective observational studies. Compared to the control, BoNT-A increased the incidence of clinically significant improvement in pain (RR = 4.82, 95% CI (3.00, 7.76), p < 0.00001) and functional improvement (RR = 3.81, 95% CI (2.40, 6.04), p < 0.00001) (low-certainty evidence), and reduced VAS score (MD = -1.62, 95% CI (-3.13, -0.11), p = 0.04) (very low-certainty evidence). Subgroup analysis showed that BoNT-A is effective against normal saline (moderate-certainty evidence), and it was comparable to steroids and local anaesthetics (very low-certainty evidence). TSA confirmed the findings regarding clinical improvement in pain and functional improvement.

CONCLUSION

BoNT-A is a tolerable and effective treatment for CLBP with a longer duration of action. Future high-quality studies are needed to confirm our findings.

SIGNIFICANCE

This paper provides good evidence that BoNT-A may be employed in patients suffering from resistant chronic low back pain not responding to normal saline injection due to its higher efficacy and longer duration of action. Compared to steroids and local anaesthetics injections, there is not enough data to draw a firm conclusion and future studies are needed.

"Veins first" versus "artery first" approach for management of mixed arterial venous leg ulcers (MAVLU): Systematic review and meta-analysis

IntroductionMixed Arterial and Venous Leg Ulcers (MAVLU) are challenging. The optimal intervention sequence (artery-first vs vein first) is unclear. This review evaluates current evidence on surgical intervention sequencing.MethodsMEDLINE, PUBMED, SCOPUS and EMBASE were searched using the term 'mixed arterial venous leg ulcers.' Studies were eligible if they reported ulcer healing outcomes in MAVLU patients. Pooled proportions were calculated by random effects modelling.ResultsThe search yielded 606 studies, eight of which contained sufficient data to include in the analysis. There were no randomized controlled trials. Initial modified compression (MCT) and rescue revascularisation in MAVLU with ABI 0.5 to 0.85 achieved a pooled healing rate of 75% (95% CI 69% to 80%) compared to 79% (95% CI 61% to 93%) in patients with standard VLUs. The pooled rescue revascularisation rate for MAVLU patients with moderate arterial disease was 25% (95% CI 6% to 51%). Patients with severe arterial disease (ABI <0.5) who underwent arterial intervention first were less likely to heal (pooled proportion 40%; 95% confidence interval 16% to 66%). No studies compared either MCT or venous ablation with arterial revascularisation as first-line in patients with moderate arterial disease (ABI 0.5 to 0.85) alone or severe arterial disease (ABI <0.5) alone. There was marked heterogeneity between studies with respect to ulcer healing outcomes reported, definitions of ulcer healing, duration and size of ulcers at presentation, use of adjunct procedures such as skin grafting, unit of measurement (legs vs patients) and duration of follow up.ConclusionA 'veins first' approach to MAVLU is plausible but robust data are lacking and should be evaluated in a randomized controlled trial.

Impact of Salpingotomy on Intrauterine Pregnancy and Recurrent Ectopic Pregnancy Rates: A Meta-Analysis

Ectopic pregnancy poses significant risks to future fertility and recurrence, and can be surgically resolved if the traditional approach is ineffective. Salpingotomy has emerged as a preferred surgical option to treat ectopic pregnancy, as it has been shown to preserve fertility and prevent recurrence. This meta-analysis assessed whether salpingotomy impacts the intrauterine pregnancy (IUP) and recurrent ectopic pregnancy (REP) rates. A literature search was conducted using PubMed, MEDLINE (Medical Literature Analysis and Retrieval System Online), Ovid Discovery, and ClinicalTrials.gov. The studies meeting the inclusion criteria were reviewed, and data from 2,220 patients were pooled. The statistical analysis was carried out using the Comprehensive Meta-Analysis Software version 4 (Biostat, Inc., Englewood, New Jersey, United States). The results showed that following salpingotomy, patients reported significantly higher IUP rates (95%CI: 0.487-0.724, p=0.000). The data analysis indicated significant variation in REP rates across the studies, suggesting a high probability of patients not experiencing REP (mean effect size=0.109, 95%CI: 0.074-0.157, p=0.03). A sub-analysis of factors was also conducted, including the impact of age, follow-up time, year of study publication, and geographic location on the IUP and REP rates following salpingotomy. There was a significantly higher number of IUPs in studies published before 2020 than those published after 2020 (mean effect size=0.598, 95%CI: 0.495-0.694, p=0.013). Also notable was a significantly higher IUP rate in patients under 30 (mean effect size=0.58, 95% CI: 0.442-0.706, p=0.007). There was no significant difference in IUP rates due to follow-up time or geographic location (mean effect size=0.613, 95%CI: 0.482-0.730, p=0.964; mean effect size=0.612, 95%CI: 0.541-0.681, p=0.341). Furthermore, REP rates were significantly higher in studies with a follow-up time longer than three years (mean event rate=0.127, 95%CI: 0.098-0.162, p=0.005). There was no significant difference in REP rates across geographic locations, age, or year of publication (p=0.380, p=0.257, and p=0.134, respectively). Overall, salpingotomy provides a higher likelihood of IUP in patients below the age of 30 and has a low risk of REP. The findings underscore the importance of individualized patient counseling, balancing the benefits of salpingotomy for fertility preservation against the risks of REP.

Anticholinergic Burden and Cognitive Function in Psychosis: A Systematic Review and Meta-Analysis

OBJECTIVE

The authors synthesized evidence from studies quantifying the relationship between anticholinergic medication and cognitive function in psychosis, and additionally explored studies that investigated whether reducing anticholinergic medications affects cognitive function in individuals with psychosis.

METHODS

A database search was conducted in MEDLINE, Embase, and PsycINFO, from database inception to October 2023, for studies reporting objective cognitive assessment and quantification of anticholinergic burden using clinical scales, serological anticholinergic activity, or tapering of anticholinergic medications. Analyses were carried out in R using the metafor package. Random-effects meta-analysis models were employed, along with assessment of heterogeneity, study quality, and meta-regressions (age, sex, and antipsychotic dosage in chlorpromazine equivalents).

RESULTS

Of 1,337 citations retrieved, 40 met inclusion criteria, comprising 25 anticholinergic burden studies (4,620 patients), six serological anticholinergic activity studies (382 patients), and nine tapering studies (186 patients). A negative correlation was identified between anticholinergic burden and global cognition (r=-0.37, 95% CI=-0.48, -0.25), verbal learning (r=-0.28, 95% CI=-0.36, -0.21), visual learning (r=-0.17, 95% CI=-0.28, -0.06), working memory (r=-0.22, 95% CI=-0.29, -0.14), processing speed (r=-0.24, 95% CI=-0.35, -0.13), attention (r=-0.19, 95% CI=-0.29, -0.08), executive functions (r=-0.17, 95% CI=-0.27, -0.06), and social cognition (r=-0.12, 95% CI=-0.19, -0.05), and between serological anticholinergic activity and verbal learning (r=-0.26, 95% CI=-0.38, -0.14), working memory (r=-0.19, 95% CI=-0.35, -0.03), and executive functions (r=-0.16, 95% CI=-0.27, -0.04). Finally, tapering off anticholinergic medication improved the scores in verbal learning (d=0.77, 95% CI=0.44, 1.1), working memory (d=0.94, 95% CI=0.63, 1.26), and executive functions (d=0.44, 95% CI=0.26, 0.62).

CONCLUSIONS

Anticholinergic burden is associated with the cognitive impairments observed in psychosis. From a clinical perspective, tapering off anticholinergic medication in patients with psychosis may improve cognition. However, randomized clinical trials are needed for an unbiased quantification of benefit.

Optimizing ward rounds: systematic review and meta-analysis of interventions to enhance patient safety

BACKGROUND

Poor quality ward rounds contribute to a large proportion of patient complications, delayed discharge, and increased hospital cost. This systematic review investigated all interventions aiming to improve patient and process-based outcomes in ward rounds.

METHODS

This systematic review was prospectively registered in PROSPERO, the international prospective register of systematic reviews (CRD42023394325). MEDLINE, Embase, Emcare, and PsycInfo were searched for studies with interventions aiming to improve ward round processes or patient outcomes in hospital settings. Studies were excluded if there was no baseline comparator or they were not in the ward round setting. Interventions were coded as checklist interventions (that is electronic or paper-based pro formas, templates, and checklists), structure interventions (that is defined rules or protocol to guide or standardize conduct), or other interventions. Outcomes were assessed via meta-analyses using the I2 statistic, Cochran's Q P value, and random-effects models. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool for RCTs and the Newcastle-Ottawa scale for non-randomized studies.

RESULTS

This review included 84 studies, from 18 countries, in 23 specialties, involving 43 570 patients. Checklist interventions significantly reduced ICU length of stay, improved overall documentation, and did not increase ward round duration. Structure interventions did not increase the time spent per patient or impact 30-day readmission rates or patient length of stay.

CONCLUSION

This is the first systematic review with meta-analyses synthesizing the evidence of all ward round interventions targeted at improving patient and process outcomes. Results from this review should be used to inform guidelines for the 'ideal ward round'.

Association between proton pump inhibitor use and migraine: a systematic review and meta-analysis

BACKGROUND

Migraine is a common neurological disorder with potential pharmacological triggers. Proton pump inhibitors (PPIs), commonly prescribed for managing gastroesophageal reflux disease and other acid-related gastrointestinal disorders, have been linked to headaches. However, their association with migraine remains unclear. This systematic review and meta-analysis assessed the association between PPI use and the incidence of migraine.

METHOD

A systematic search of PubMed, Embase, and Web of Science was conducted in accordance with the PRISMA framework and registered with PROSPERO (ID: CRD42025644604) to enhance transparency. The search, conducted up to January 2024, included studies focusing on the association between migraine and PPI use. Data screening and extraction were performed using Nested Knowledge software. Meta-analyses were conducted in R software, with heterogeneity assessed through the I² statistic. Pooled adjusted odds ratios (aORs) with 95% confidence intervals (CIs) were calculated using a random-effects model. Sensitivity analyses were also performed to assess the robustness of the results. Gender and migraine subtype were considered in subgroup analyses. Additionally, the GRADE approach was applied to assess the certainty of the evidence across the pooled outcomes.

RESULTS

Five studies involving over 1.5 million participants met the inclusion criteria. The overall pooled adjusted odds ratio (aOR) was 2.508 (95% CI, 0.790-7.969; I² = 91.2%). However, there was a significant association in males (aOR, 3.875; 95% CI, 2.413-6.222; I² = 0%) but not in females (aOR, 2.475; 95% CI, 0.563-10.890; I² = 91.1%). No significant differences were found between migraine types: with aura (aOR, 2.079; 95% CI, 0.945-4.576; I² = 25.4%) and without aura (aOR, 2.524; 95% CI, 0.807-7.896; I² = 96.5%). The GRADE assessment indicated a very low certainty of the evidence.

CONCLUSION

This review found no significant overall association between PPI use and migraine. However, a significant association was observed in males but not in females. Further research is needed to clarify this association and explore the underlying causality mechanisms, and migraine subtypes, particularly why the association appears more pronounced in males.

Prognostic Significance of B7H3 Expression in Solid Tumors: A Systematic Review and Meta-Analysis

B7H3 (CD276), an immunoregulatory molecule known for its role in immune evasion by transmitting inhibitory signals to T lymphocytes, has garnered significant attention in recent years as a promising target for cancer immunotherapy. This interest is largely due to its high expression in various types of solid tumors, coupled with low protein levels in normal tissues. However, studies examining the impact of B7H3 on survival outcomes have shown inconsistent results, leaving its prognostic significance not fully clarified. Therefore, this meta-analysis aimed to assess the relationship between B7H3 expression and various prognostic parameters in patients with solid malignancies. PubMed, Web of Science (WOS), Cochrane, SCOPUS, and Embase databases were searched for eligible articles published until November 2024. Statistical analysis was performed using R studio (version 4.3.2). The analysis included a total of 51 eligible studies comprising 11,135 patients. Results showed that overexpression of B7H3 is a negative predictor for all examined survival outcomes: OS (HR = 1.71, 95% CI = 1.44-2.03, p < 0.0001), DFS (HR = 2.02, 95% CI = 1.49-2.73, p < 0.0001), PFS (HR = 2.10, 95% CI = 1.44-3.06, p < 0.0001), RFS (HR = 1.66, 95% CI = 1.11-2.48, p = 0.01), and DSS (HR = 1.70, 95% CI = 1.24-2.32, p < 0.01). Despite the high heterogeneity observed across the studies, the sensitivity analysis confirmed the robustness of these results. This research suggests that B7H3 may serve as an effective biomarker for prognosis in solid tumors.

Carbapenem-resistant Enterobacterales (CRE) in Indonesia: protocol for systematic review and meta-analysis

Background

Carbapenem-resistant Enterobacterales (CRE) pose a significant global health threat, with increasing prevalence worldwide, including in Indonesia. Despite the public health impact, comprehensive data on the burden of CRE in Indonesia remains fragmented. This protocol outlines a systematic review and meta-analysis aiming to estimate the prevalence of CRE in Indonesia, summarize trends over time, and identify key resistance mechanisms.

Methods

We will conduct a systematic search across multiple electronic databases, including PubMed, Scopus, and local Indonesian databases, for studies reporting the prevalence of CRE in Indonesia from 2004 to 2024. Eligibility criteria include observational studies (cross-sectional, cohort, and case-control) and surveillance reports. Data extraction will focus on CRE prevalence, bacterial species, sample types, resistance mechanisms, and study settings (hospital vs. community). Quality assessment of studies will be performed using the Newcastle-Ottawa Scale (NOS). Meta-analysis will be conducted using a random-effects model to estimate pooled prevalence, and subgroup analysis will explore variations by geographical region, period, and healthcare setting.

Discussion

This systematic review and meta-analysis will provide the first comprehensive overview of CRE prevalence in Indonesia, contributing to an improved understanding of the national burden and resistance patterns. The findings will guide public health policies and inform antimicrobial stewardship efforts in Indonesia.

The Oncological Outcome of Postoperative Radiotherapy in Patients with Node-Negative Early-Stage (T1/T2/N0) Oral Squamous Cell Carcinoma and Perineural Invasion: A Meta-Analysis

Objective: To evaluate the impact of postoperative radiotherapy (PORT) on oncological outcomes in node-negative early-stage oral squamous cell carcinoma (OSCC) with perineural invasion (PNI). Methods: A systematic review and meta-analysis was conducted using the PubMed, EMBASE, and Scopus databases for the period from 2000 to 2024. Studies comparing PORT versus observation in pN0 early-stage OSCC with PNI were included. Oncological outcomes assessed included overall survival (OS), disease-free survival (DFS), and local control (LC). A random-effects model was used to calculate log odds ratios, and heterogeneity was assessed using tau2, chi2, and I2 statistics. Results: Seven retrospective studies comprising 522 patients (281 PORT, 241 no-PORT) were included. The 3-year overall survival (OS) was 86.3% in the PORT group compared to 71.1% in the no-PORT group (logOR = -1.03, p = 0.0012), while the 5-year OS was 88.1% versus 77.3% (logOR = -0.97, p = 0.0061). Disease-free survival (DFS) also favored PORT, with 3-year DFS at 86.3% versus 58.1% (logOR = -1.19, p < 0.001) and 5-year DFS at 86.3% versus 55% (logOR = -0.78, p = 0.003). Local control (LC) was higher in the PORT group, with 3-year LC rates of 89% compared to 72.2% in the no-PORT group (logOR = -1.13, p = 0.025). Conclusions: PORT significantly improves OS, DFS, and LC in node-negative early-stage OSCC with PNI as the sole adverse feature.

Preference of mode of delivery and associated factors among mothers in East Africa: systematic review and meta-analysis

INTRODUCTION

Preference of mode of delivery refers to the expectant mother's personal choice or preference for the method by which she would like to have her baby delivered. Although there are many fragmented primary studies on the preference of mode of delivery among women in East Africa, the pooled preference rate is unknown. In addition, those studies disagreed on reporting the associated factors. Therefore, this study was intended to determine the pooled preference for mode of delivery and its associated factors among women in East Africa.

METHOD

We searched studies using PubMed, Scopus, Embase, Science Direct, and Google Scholar that were published between March 01/2014 and March 31/2024. This study used the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The quality of studies was evaluated using the modified Newcastle-Ottawa quality assessment tool. The data were extracted by two authors independently using Microsoft Excel and analyzed by Stata version 17. A random effects model was applied to calculate the pooled preference for mode of delivery and its associated factors. The PROSPERO registration number for the review was CRD42024541921.

RESULTS

A total of 14 studies comprising 47,561 participants were involved in this meta-analysis. The pooled preference of vaginal delivery and cesarean delivery were 75% ((95% C.I = 67 - 83%) and 25% (95% C.I = 17 - 34%), [Formula: see text]respectively. This study showed that ANC-follow (OR= 1.11; 95% CI=0.67-1.82), previous intrapartum satisfaction (OR= 2.69; 95% CI = 0.53-13.64), place of residence (OR= 1.10; 95% CI = 0.86-1.42), occupation (P=0.000; OR= 0.97; 95% CI=0.67-1.42), planned pregnancy (OR= 1.89; 95% CI=1.26-2.82), previous history of spontaneous abortion (OR= 2.30; 95% CI=0.71-7.44), current pregnancy related problem (OR= 3.86; 95% CI=1.37-10.84), discussion with a partner (OR= 0.67; 95% CI=0.35-1.27), types of the hospital (OR= 1.13; 95% CI = 0.65-1.94) were significant factors associated with preference of mode of delivery.

CONCLUSION

The preference for vaginal delivery was higher than for cesarean delivery. Factors such as antenatal care follow-up, previous intrapartum satisfaction, place of residence, occupation, planned pregnancy, prior history of spontaneous abortion, maternal education, current pregnancy-related problems, discussion with partner, and types of hospital were significantly associated. The findings of this study imply a multifaceted approach is required.

Prevalence of neglected tropical diseases among migrants living in Europe: A systematic review and meta-analysis

BACKGROUND

Migration to Europe has intensified due to recent political conflicts, economic crises, and climate change, introducing an increased risk of neglected tropical diseases (NTDs) within this population. While NTDs typically impact tropical regions, their presence among migrants in Europe presents a growing challenge, compounded by limited research in this area. This study provides the first meta-analysis on the prevalence of NTDs in migrants across European nations.

METHODS

A systematic review and meta-analysis was conducted focusing on studies that included NTD prevalence among migrant populations in Europe, with data sourced until July 2024. Cross-sectional and longitudinal studies were eligible, with bias assessed using the Newcastle-Ottawa Scale. Prevalence rates for various NTDs were calculated using a random-effects model, and meta-regressions were performed to assess potential moderators like sample size, age, and gender.

RESULTS

A total of 148 studies comprising 228,798 migrants were analyzed. The most prevalent NTDs were strongyloidiasis (11.53 %) and schistosomiasis (10.8 %), with American trypanosomiasis also present. Dengue and lymphatic filariasis showed significant rates, though high heterogeneity was noted. Data quality was frequently low, with most studies at a high risk of bias.

CONCLUSIONS

This study underscores the need for robust screening and diagnostic protocols in Europe for NTDs, particularly as clinician familiarity with these diseases is limited. Test-and-treat strategies appear promising, yet more comprehensive efforts are necessary. Establishing a European NTD registry could improve monitoring and management. Future studies should prioritize higher-quality data and address the barriers migrants face in accessing health services.

Psychological Stress Reduces the Effectiveness of Periodontal Treatment: A Systematic Review

Background/Objectives: To systematically evaluate scientific evidence related to the influence of psychological stress on the response to periodontal treatment. Methods: PubMed/NCBI (National Center for Biotechnology Information, US National Library of Medicine), Web of Science (ClarivateTM), EBSCOHost, SCOPUS, and ProQuest databases were searched for published clinical studies in English up to May 2024. The quality of each study was assessed using the Ottawa-Newcastle scale. Results: Of 803 relevant articles identified, 8 were included in the qualitative synthesis qualitative synthesis. These studies involved 445 patients who completed the follow-up period, ranging from 6 weeks to 6 months. Stressed patients were more likely to experience higher levels of PPD and BOP compared to non-stressed patients. In total, 75% of the included studies showed a positive relationship between stress and response to NSPT, 12.5% observed a negative relationship, and the remaining 12.5% found some degree of relationship in the results of clinical periodontal parameters. The level of evidence is categorized according to the quality of the synthesis presented. Conclusions: There is a positive correlation between psychological stress and periodontal treatment response, indicating that stress may negatively influence the clinical outcomes of NSPT. Stress may reduce the inflammatory response, which is crucial for eliminating periodontal micropathogens after periodontal treatment.

Effect of the Mediterranean diet on incidence of heart failure in European countries: a systematic review and meta-analysis of cohort studies

INTRODUCTION

Heart failure (HF) is one of the most common cardiovascular disorders, and its prevalence is increased due to age, genetics, and lifestyle factors. Emerging evidence suggests that the Mediterranean Diet (Med Diet) is linked to lower all-cause mortality in patients with increased cardiovascular disease risk, such as those with HF.

OBJECTIVE

To conduct a systematic review and meta-analysis of observational studies into the relationship between the Med Diet on HF risk.

DESIGN

Several databases (PubMed, Scopus, Web of Science and Cochrane Library) until the 01st of May 2023 were searched. Our research was conducted based on the updated 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were reported as risk ratios (RRs) with their 95% confidence intervals (CIs) as results of multivariate or univariate analyses.

RESULTS

From the original 1206 studies collected, six observational prospective studies were included, with a total of 216,385 European participants without evidence of HF at baseline. Over a mean period of 11 years of follow-up, a 1-point increase in the Med Diet score was associated with a significantly lower risk of HF (RR = 0.940; 95% CI: 0.912-0.969, p < 0.0001; I2 = 42.9%). Categorised by sex, a higher adherence to Med Diet was associated with a significantly lower incidence of HF in women (RR = 0.942; 95% CI: 0.912-0.973, p = 0.001; I2 = 41.8%), but not in men. The overall quality of included studies was good.

CONCLUSIONS

Higher adherence to Med Diet across European countries is associated with lower risk of HF, particularly in women.

Revisional bariatric surgery following sleeve gastrectomy: a meta-analysis comparing Roux-en-Y gastric bypass and one anastomosis gastric bypass

INTRODUCTION

The number of bariatric operations is increasing each year. Sleeve gastrectomy is the most popular procedure; however, it often requires revision surgery because of insufficient weight loss, weight regain or gastro-oesophageal reflux disease (GORD). The most popular revisional procedures are Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB). The primary outcome of this meta-analysis was weight loss after revisional surgery following laparoscopic sleeve gastrectomy and the secondary outcomes were gastro-oesophageal reflux, BMI difference, operative time, bleeding and anastomotic leak.

METHODS

A systematic electronic search was undertaken using PubMed, MEDLINE, Ovid, Cochrane Library and Google Scholar following PRISMA guidelines. The initial search identified 2,546 articles. After screening, seven papers met the inclusion criteria: six retrospective studies and one randomised controlled trial.

RESULTS

In total, 802 patients met the inclusion criteria: 390 had an OAGB and a further 412 had an RYBG. All patients previously had a sleeve gastrectomy for weight loss. The length of follow-up was 12 months for our primary outcome. We found no statistically significant difference in excess weight loss (%EWL) between OAGB and RYGB (p = 0.11). The incidence of postoperative reflux was statistically significantly higher in the OAGB group (16% vs 10.1%, p < 0.003). Operative time was statistically significantly lower in the OAGB group (p = 0.04).

CONCLUSIONS

This meta-analysis showed no statistically significant difference between the two revision bariatric surgery procedures for %EWL. RYGB was superior to OAGB in reducing the incidence of symptomatic GORD, whereas OAGB had a significant shorter operative time.

Astrocytomas IDH-mutant of posterior cranial fossa, clinical presentation, imaging features and onco-functional balance in surgical management

IDH-mutant astrocytomas (AIDHmut) in the posterior cranial fossa (PCF) are rare and present substantial diagnostic and therapeutic challenges due to their location. We analyzed patients with PCF AIDHmut from our institutions, treated between December 2021 and September 2024. Additionally, we conducted a systematic literature review (from January 2021 to September 2024) using PubMed, Ovid MEDLINE, and Ovid EMBASE to identify cases of PCF AIDHmut. We identified a total of 19 cases, including one institutional case. Most patients were young adults, with a male predominance (15 males, 4 females). Tumors primarily originated from the brainstem (94.7%), with only one case involving the cerebellum. Clinical presentations frequently included cranial nerve deficits, with diplopia being the most common symptom (47.4%). Adjuvant radiotherapy (IMRT, DT 54 Gy/27 fractions, 78.9%) and chemotherapy (temozolomide, 68.4%) formed the mainstays of treatment. Tumor grading revealed 63.2% (12/19) were WHO grade 2, 21% (4/19) were WHO grade 3, and 15.8% (3/19) were grade 4. The mean follow-up period was 45 months. PCF AIDHmut are rare but pose significant treatment challenges due to their location and infiltrative nature. Multimodal treatment-comprising surgery, radiotherapy, and chemotherapy-is essential for achieving long-term disease control. Subtotal resection followed by adjuvant therapies provides a favorable balance between tumor control and functional preservation.

Mental health status and quality-of-life after an acute myocardial infarction with non-obstructive coronary arteries or takotsubo syndrome: A systematic review

BACKGROUND

Myocardial infarction with non-obstructive coronary arteries (MINOCA) and takotsubo syndrome (TS) are both characterised by lack of significant coronary artery stenoses and a higher prevalence of mental health disorders preceding the event. Currently, little is known about their pathological aetiologies and subsequent treatment plans, giving cause for concern among those affected. The objective of this review is to provide a comprehensive overview of mental health status and quality of life (QoL) in MINOCA- and TS-patients after the acute event, compared to both cardiac and non-cardiac populations, and over time.

METHODS

A systematic search was conducted via Cochrane Library, CINAHL, PyschINFO, PubMed, ASSIA, Web of Science, Scopus and Embase from inception to May 2024. The review was registered in PROSPERO and methods, and results were reported in accordance with the PRISMA guidelines. Quality assessment and risk of bias were evaluated using the Newcastle-Ottawa Scale for cross-sectional and cohort studies.

RESULTS

Sample sizes ranged from 13 to 5,322 participants. The risk of bias was high in 18/28, medium in 7/28, and low in 3/28 studies. Across the symptoms assessed, MINOCA- and TS-patients reported worse mental health status or QoL than non-cardiac groups in 10/13 studies, and cardiac groups in 10/20 studies. Investigating change over time, 1/5 studies found deteriorating mental health status, 3/5 reported improved mental health status or QoL and 1/5 reported no change in MINOCA- and TS-patients.

CONCLUSIONS

Patients with MINOCA or TS seem to have worse mental health status and QoL after the acute event than non-cardiac individuals, but it is yet difficult to conclude whether mental distress and QoL are equal or worse compared to CHD-patients. There is no convincing evidence that mental health status or QoL of MINOCA- and TS- patients naturally improve over time after the acute event. Among the studies evaluated, risk of bias was high. More high-quality studies are needed, investigating mental health status and QoL among MINOCA- and TS-patients.

The association of selenium exposure with the odds of metabolic syndrome: a dose-response meta-analysis

BACKGROUND

Selenium is a key regulator of metabolic homeostasis. It has been proposed that exposure to selenium might be associated with metabolic syndrome (MetS). However, the results are contradictory. This meta-analysis was carried out to analyze the relationships between selenium levels in biological samples and odds of Mets.

METHODS

We searched Scopus and PubMed databases up until September 2024 to identify relevant studies. Odds ratio (OR) and 95% confidence interval was used to pool the data using a random effects model.

RESULTS

The meta-analysis encompassed 18 observational studies involving 21,481 participants. It found that higher selenium exposure was related to an elevated likelihood of MetS (OR = 1.30, 95% CI = 1.12-1.51), even after controlling for covariates, such as smoking, age, alcohol consumption, and physical activity. Heterogeneity was significant among the studies (I² = 88.9%, P = 0.001). While elevated serum selenium levels linked to a higher odds of MetS, no such relationship was observed for selenium in urine or toenails. Subgroup analyses indicated that this association was evident only in females (OR = 2.0, 95% CI = 1.17-1.43) and particularly pronounced in individuals aged ≥ 50 years. A dose-response relationship was identified, showing a 6% increase in MetS odds for each additional 10 µg/L of serum selenium, with the odds rising non-linearly when serum levels surpassed 80 µg/L.

CONCLUSIONS

This study suggests that selenium may associated with the odds of MetS, following a dose-response relationship.

Investigating factors affecting the quality of life of women with gestational diabetes: a systematic review and meta-analysis

BACKGROUND

Gestational diabetes mellitus (GDM) affects a significant proportion of pregnant women, impacting both physical and psychological well-being. This study aimed to investigate the factors influencing quality of life (QoL) in women with GDM.

METHODS

This systematic review followed PRISMA guidelines and was registered in PROSPERO (ID: CRD42024612587). A comprehensive search was conducted in PubMed, Scopus, ProQuest, Web of Science, and CINAHL, using MeSH terms related to gestational diabetes and quality of life. Eligible studies included adult women with gestational diabetes and assessed factors influencing their quality of life. The included studies were related to various stages including antenatal, during pregnancy or postpartum. Data extraction was performed independently by two authors, and study quality was evaluated using the Newcastle-Ottawa Scale (NOS). Statistical analyses were conducted in STATA, including meta-analysis with a random-effects model.

FINDINGS

The findings reveal that women with GDM experience significantly lower QoL compared to healthy pregnant women, with sexual dysfunction being a notable contributor. Women with GDM reported lower sexual desire, satisfaction, and higher pain levels, which were significantly associated with poorer QoL, particularly in mental health and pain domains. Socio-demographic factors such as age, education, income, and marital status were significantly linked to QoL, with younger women and those with lower education or income reporting poorer outcomes. Psychological factors, including stress, depression, and anxiety, negatively impacted QoL, while social support, self-efficacy, and illness acceptance were positively correlated with better QoL outcomes. Additionally, stress was found to be the main predictor of QoL for women over 30, while social relationships were more important for younger women. Treatment with insulin or a combination of insulin and oral hypoglycemic agents was associated with lower QoL compared to dietary management alone.

CONCLUSION

This systematic review identified key psychosocial and medical factors influencing the quality of life in women with gestational diabetes. The findings emphasize the importance of addressing psychological well-being, social support, and treatment approaches to enhance QoL in these women. Further research is needed to explore interventions targeting mental health and stress management to improve outcomes for women with gestational diabetes.

Poor glycemic control and its predictors among people living with diabetes in low- and middle-income countries: a systematic review and meta-analysis

INTRODUCTION

Variability in blood glucose remains a challenge in diabetic management. Therefore, this review aimed to estimate the overall poor glycemic control and identify its predictors among people living with diabetes in low- and middle-income countries (LMICs).

METHODS

The authors searched articles in PubMed, Embase, OVID, CINAHL Plus, Cochrane Library, PsychInfo, Google, and Google Scholar. The search results were exported to the Rayyan software to check their eligibility. The Newcastle-Ottawa scale was used to assess the study quality. Stata version 17 was used for analysis. A random effect model was computed. Heterogeneity was assessed by the Cochrane Q test and I-squared (I2). The funnel plot asymmetry test and/or Egger's regression test (p < 0.05) were used to detect the publication bias. Then it was treated by the trim and fill analysis. The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) with the reference number CRD42023430175.

RESULTS

In total, forty-nine articles were used. Of which forty-five articles with 15,981 participants were used for pooled prevalence estimation. The pooled prevalence of poor glycemic control among people living with diabetes in LMICs was found to be 69.06% (95% CI: 65.66-72.46), I2 = 96.1%, p < 0.001). Alcohol intake (AOR = 2.07: 95% CI: 1.27-3.36), poor adherence to dietary recommendations (AOR = 3.16, 95% CI: 1.13-8.85), poor adherence to anti-diabetic medication (AOR = 2.85, 95% CI: 1.04 -7.85), diabetic complications (AOR = 1.37, 95% CI: 1.00-1.88), and co-morbid conditions (AOR = 1.98, 95% CI: 1.28-30.07) were found to be predictors of poor glycemic control.

CONCLUSIONS

The pooled prevalence of poor glycemic control was significantly high in LMICs. Drinking alcohol, poor adherence to dietary recommendations, poor adherence to anti-diabetic medication, diabetes complications, and co-morbid conditions were found to be the determinants of poor glycemic control among people living with diabetes. Tight glycemic control strategies have been implemented to achieve optimal blood glucose. Further research on the regional and contextual factors influencing glycemic control would be recommended.

Triglyceride glucose-waist circumference as a predictor of mortality and subtypes of cardiovascular disease: a systematic review and meta-analysis

BACKGROUND

The significant burden of cardiovascular diseases underscores the necessity for identifying novel predictive markers that can forecast both cardiovascular diseases and mortality. In recent years, TyG-obesity-related parameters have gained special attention in this regard. This study aimed to assess the association between TyG-waist circumference (TyG-WC) and cardiovascular diseases and mortality.

METHODS

A comprehensive search was performed in databases including PubMed, Scopus, and Web of Science from their inception until October 6, 2024. The key outcomes of interest included all-cause mortality, cardiovascular mortality, cardiovascular diseases, myocardial infarction, stroke, coronary artery diseases, peripheral artery diseases, and heart failure. The pooled risk ratio (RR) with corresponding 95% confidence intervals (CI) was calculated. Meta-analysis was carried out using StataMP 14.0.

RESULTS

A total of 17 studies were included in the analysis. The number of participants ranged between 2,224 and 95,342. The meta-analysis revealed that TyG-WC is significantly associated with an increased risk of all-cause mortality, cardiovascular mortality, cardiovascular diseases, myocardial infarction, stroke, coronary artery diseases, and peripheral artery diseases. However, only one study addressed the relationship between TyG-WC and heart failure with a positive correlation.

CONCLUSION

This study indicates that TyG-WC could serve as a promising predictor of cardiovascular diseases, along with cardiovascular and all-cause mortality. Given its accessibility, TyG-WC may be a practical tool for screening purposes.

Prevalence of depression among primary caregivers of patients with cancer in Africa: a systematic review and meta-analysis study

Background

Cancer is one of the main causes of the most extremely stressful events that can elicit emotional reactions such as depression. Cancer patient caregivers are the most involved members of the oncology team and play an important role in patient's disease management and palliation which may adversely affect their health in the longer run, but many times the caregiver has been overlooked and ignored team. A corresponding systematic review on this topic has not yet been undertaken, even though there have been several studies about depression among primary caregivers of patients with cancer in Africa.

Methods

To find studies, we searched databases such as PubMed, Scopus, Cochrane Library, Science Direct, African Journal Online, and Google Scholar. A Microsoft Excel spreadsheet was used to extract the data, which were then transferred to STATA version 14 for analysis. The statistical heterogeneity was evaluated by using Cochran's Q and I 2 statistics. To identify publication bias, Egger regression tests and funnel plot analysis were used. Sensitivity and subgroup analyses were carried out.

Results

The current systematic review and meta-analysis comprised all 1983 research respondents from 10 studies. The overall pooled prevalence of depression among primary caregivers of patients with cancer was 47.21% with a 95% CI (31.76, 62.65: I 2 = 98.4%). According to subgroup analysis, the pooled prevalence of depression was higher in the studies that used the back depression inventory screening tool (63.95%) (95% CI: 58.76, 69.13). Additionally, we observed a high pooled prevalence of depression in existing studies conducted in Kenya (62.7%) (95% CI: 56.45, 68.95). Finally, a greater prevalence of depression was found among primary caregivers of children with cancer (64.61%) (95% CI: 58.19, 71.03).

Conclusion and recommendations

The current systematic review and meta-analysis showed that depression was prevalent among primary caregivers of patients with cancer in Africa. The study also highlighted variability in prevalence based on country, method of depression assessment, and population subgroups. Therefore, public health interventions targeting the mental health of caregivers should be promoted. Priority should be given to those who care for children.

Perioperative Neurocognitive Disorder in Individuals with a History of Traumatic Brain Injury: Protocol for a Systematic Review and Meta-Analysis

Postoperative neurocognitive disorder (PND) is a cognitive decline after general anesthesia and surgery, influenced by preexisting neurodegenerative conditions, stress, and inflammation. Traumatic brain injury (TBI) is linked to a dysregulated stress response, neuroinflammation, and cognitive issues. Patients with TBI often need extracranial surgeries under general anesthesia (GA), which can increase stress, neuroinflammation, and neurodegenerative changes, raising PND risk. We will search databases like Ovid Medline and Embase for studies on cognitive function in patients with mild to moderate TBI who had extracranial surgeries under general anesthesia (GA). Screening and data extraction will be done manually and with AI-assisted tools (ASReview). Study quality will be assessed using the Newcastle-Ottawa Scale. Statistical analyses will include mean differences, odds ratios, and meta-regression, addressing heterogeneity, sensitivity, and publication bias using Stata/SE. By meta-analyzing clinical studies, we aim to determine if TBI and GA/surgery interact to induce PND. We will use various data sources, subgroup analyses, sensitivity analyses, and meta-regression to assess factors like age, gender, and type of GA/surgery. This meta-analysis will enhance our understanding of PND risks, inform clinical practices, and highlight new research directions. The systematic review is registered in PROSPERO (CRD42024510980).

Association of sulfur mustard toxicity with oxidant/antioxidant system in veterans: A meta-analysis of case-control studies

Sulfur mustard (SM) is a chemical warfare agent that increases oxidative stress in veterans. The literature assessing oxidant/antioxidant parameters in SM-exposed veterans contains conflicting results. A total of 11 relevant studies were identified and screened. Data were extracted, and effect size and heterogeneity were assessed. The analysis revealed significant elevations in levels of malondialdehyde (MDA, an indicator of lipid peroxidation), catalase (CAT), and a reduction in glutathione (GSH) following SM exposure while superoxide dismutase (SOD) and total antioxidant levels did not change. The meta-analysis revealed that the MDA and CAT levels significantly increased in the two post-exposure sampling times (15-20 and 21-33 years) except for theGSH level, which decreased only in the post-exposure sampling time of 21-33 years. The subgroup meta-analysis of the type of analyzed samples indicated that SOD and CAT levels were only increased in the serum/plasma samples, while GSH was decreased. BALF/sputum and erythrocyte samples also revealed significant increases in MDA and SOD levels while GSH level was significantly decreased. This meta-analysis concluded that SM exposure affects the balance between oxidants and antioxidants, promoting oxidative stress that may persist long after exposure. This condition highlights the need for strategies to enhance antioxidant defenses in SM-exposed veterans.

Determinants of adherence to the Mediterranean diet among individuals with type 2 diabetes mellitus living in Mediterranean countries: a systematic review

Background

Patients with type 2 diabetes mellitus (T2DM) are often encouraged to adopt a healthy diet, such as the Mediterranean Diet (MD) yet limited evidence exists about adherence. An increased shift toward a "Western" dietary pattern was observed.

Objective

This systematic review aims to gain insight into the various factors that may enhance or reduce adherence to the MD in patients with T2DM residing in Mediterranean countries.

Method

We retrieved published studies from 2000 to 2023 from PubMed, Cochrane, Embase, CINAHL, Web of Science, Medline, and PsycINFO databases. The criteria for inclusion included individuals residing in Mediterranean countries aged 18+ with T2DM who underwent assessment using a validated MD scoring tool. We included 17 studies, with participant numbers ranging from 106 to 7,447.

Results

Compliance with the MD was moderate, with the most significant determinants of adherence being age, physical activity, body mass index (BMI), marital status, and educational level. However, limited information is available on psychological and economic determinants.

Conclusion

Various factors, especially sociodemographic ones, influence adherence to the MD among patients with T2DM. Future research should explore economic and psychological factors that may significantly impact adherence.

Association of chronic exercise with markers of cardiometabolic health: a systematic review and meta-analysis

BACKGROUND

The impact of chronic exercise on cardiometabolic risk is a crucial aspect of public health. However, limited knowledge exists regarding differences in cardiometabolic parameters between older athletes, older controls, and sedentary or active young controls.

METHODS

A comprehensive search in major databases until October 2024 was conducted for studies comparing older athletes with older controls or with both sedentary and active younger adults. Mean differences (MDs) with 95 % confidence intervals were used for data reporting.

RESULTS

From 25,910 screened studies, 61 studies including 75 cohorts were deemed of good quality, encompassing 1393 older athletes, 1369 older controls, 402 young sedentary controls, and 283 young active individuals. In comparison to older controls, older athletes exhibited significantly improved vascular parameters (systolic [MD=-5.04 mmHg] and diastolic [MD=-2.03 mmHg] blood pressure), cardiac (heart rate frequency [MD=-10.41 bpm]), and metabolic parameters (serum cholesterol profile). Conversely, when compared to young sedentary controls, older athletes displayed a less favorable blood pressure and metabolic (cholesterol, glucose) profile. Similar trends were observed when comparing older athletes to young active controls. Sensitivity and meta-regression analyses suggested that exercise lasting over 30 years might offer partial benefits for several markers of cholesterol and VO2max.

CONCLUSIONS

Long-term exercise is linked to a more optimal cardiometabolic profile, although it may not fully replicate the metabolic and cardiovascular health markers observed in younger individuals.

Monovision versus multifocality for presbyopia during primary phacoemulsification: systematic review and network meta-analysis

This systematic review and network meta-analysis (NMA) focuses on comparing monovision and bilateral multifocal lenses (bMFIOL) implantation methods in treating presbyopia, a common age-related condition often seen in post-cataract surgery patients. This review focuses on evaluating the efficacy, user satisfaction and limitations of these two approaches through direct or indirect comparison. A comprehensive search was conducted in Medline, Embase, and Cochrane library, considering studies up to 15 July 2022, with direct or indirect comparisons between any monovision and bMFIOL implantation with bilateral cataract surgery. The study protocol has been published in the International Prospective Register of Systematic Reviews (PROSPERO, CRD42022340257). Thirty-two studies (3082 patients) were included in the NMA for the primary outcome, complete post-operative spectacle independence. NMA showed monovision to be inferior to bMFIOLs, as bMFIOL was more likely to provide complete spectacle independence (RR = 2.06, 95% CI = 1.34 to 3.15, p = 0.002) compared to monovision. Monovision resulted in less glare compared to bMFIOL (RR = 0.343, 95% CI = 0.181 to 0.651, p = 0.001). There was no statistically significant difference between monovision and bMFIOL for binocular unadjusted distance visual acuity (MD = 70.01, 95% CI = -19.88 to 4.60, p = 0.437) and binocular unadjusted near visual acuity (MD = 5.46, 95% CI = -5.24 to 10.94, p = 0.191). When compared to monovision, bMFIOL provided greater complete spectacle independence at the expense of greater glare. This study was limited by data heterogeneity, and further studies with standardized reporting would be useful.

The burden of brucellosis in donkeys and its implications for public health and animal welfare: A systematic review and meta-analysis

Background and Aim

Brucellosis is a globally significant zoonotic disease affecting a wide range of wild and domestic animals, with implications for human and animal health. Despite donkeys' crucial roles in agriculture, transportation, and livelihoods, there is limited research on the burden of brucellosis in this species. This study systematically reviews the prevalence and role of donkeys as reservoirs for Brucella spp., providing insights into their public health implications.

Materials and Methods

Using the PRISMA guidelines, a systematic search of PubMed, Scopus, and Google Scholar was conducted for studies published from 1990 to May 2024. Out of 1159 retrieved articles, 20 met the inclusion criteria. Data on study design, location, diagnostic methods, and brucellosis prevalence were extracted and analyzed using R statistical software. Pooled prevalence and heterogeneity were calculated, and the Newcastle-Ottawa Scale was employed to assess study quality.

Results

The pooled prevalence of brucellosis in 6785 donkeys across 20 studies was 10.23% (range: 0%-63.7%), with the highest prevalence reported in Asia (26.80%). While 15% of studies suggested that donkeys act as reservoirs for Brucella spp., direct evidence linking donkeys to disease transmission remains scarce. The disease's impact on donkey reproduction, including abortion and infertility, is underexplored, highlighting a significant research gap.

Conclusion

Brucellosis in donkeys represents a notable zoonotic and occupational risk. The limited data from East Africa, despite its high donkey population, emphasize the need for comprehensive epidemiological studies. Findings underscore the importance of targeted interventions, including biosecurity, public education, and enhanced diagnostic approaches, to mitigate brucellosis' impact on donkey health and its broader public health implications.

Effectiveness of ultrasonography in the diagnosis of temporomandibular joint disorders: A systematic review and meta-analysis

BACKGROUND

Temporomandibular disorders (TMDs) pose diagnostic challenges, and selecting appropriate imaging modalities is crucial for accurate assessment. This study aimed to compare the diagnostic accuracy and efficacy of ultrasonography (US) and magnetic resonance imaging (MRI) in identifying TMDs.

METHODS

A comprehensive meta-analysis was conducted, including studies that compared US and MRI for TMJ disorder assessments. Fixed-effects models were utilized to calculate pooled odds ratios (ORs) and relative risks (RRs) with 95% confidence intervals (CIs). Heterogeneity was assessed using the chi-squared test and I2 statistic. Newcastle-Ottawa scale was used to assess the methodological quality of the studies included.

RESULTS

Six studies were included, involving a total of 281 participants. The meta-analysis demonstrated that MRI was statistically somewhat better than US in identifying TMJ disorders. The summary OR was 0.64 (95% CI: 0.46-0.90), and the summary RR was 0.80 (95% CI: 0.68-0.95). Heterogeneity among the studies was low (χ2 = 2.73, df = 5, p = .74; I2 = 0%). Demographic variables revealed variations in sample size, gender ratio and mean age across the studies.

CONCLUSION

This meta-analysis provides evidence that MRI may be more effective than US in diagnosing TMDs. However, the study is limited by the small number of included studies and variations in demographic variables and study designs. Future research with larger samples and standardised protocols is essential to confirm and strengthen these findings. Understanding the diagnostic accuracy of MRI and US for TMJ disorders will aid clinicians in making informed decisions for effective TMJ disorder assessments and patient management.

Child developmental outcomes associated with postpartum depression and anxiety in low and middle-income countries: a systematic review

AIMS

This systematic review aims to summarize the findings of empirical studies conducted in low- and middle-income countries (LMICs) examining the relationship between postpartum depression and anxiety, and child developmental outcomes measured at 24 months of child's age.

METHODS

The study was performed as per PRISMA guidelines for a systematic review. EBESCO, ProQuest, PubMed, Science Direct, Google Scholar, and BMJ databases were examined, along with a forward and backward examination of the citations published. The New Ottawa scales (NOS) was used to assess the quality of the studies. The findings of the studies were integrated using a narrative synthesis approach.

RESULTS

The systematic review revealed that there are 14 studies examining the impact of postpartum depression (n=14) and postpartum anxiety (n=2) across different domains of child development in LMICs. Studies varied regarding the severity and duration of maternal depression, the context and nature of evaluation, and motherinfant characteristics which are important to understand the association between postpartum depression and anxiety and infant development. Maternal depression is negatively associated with language development, socio-emotional and behavioural development while its association with motor and cognitive development is inconsistent. The impact of maternal anxiety on infant development was examined in two studies, and both have identified a negative association. However, the results of the current review need to be interpreted within the scope and limitations of the methodologies adopted by each study details of which are elaborated in the manuscript.

CONCLUSION

Postpartum depression and anxiety can have a wide range of effects on child development. Therefore, periodic infant developmental assessments should become part of routine psychiatric evaluation. There is a need for uniform guidelines for conducting studies and reporting data related to postpartum mental health and child development.

The association between gonadectomy and timing of gonadectomy, and the risk of canine cranial cruciate ligament disease: A systematic review and meta-analysis

OBJECTIVE

To determine if gonadectomy in dogs is associated with the risk of cranial cruciate ligament disease (CrCLD) and to quantify the magnitude of the association.

STUDY DESIGN

Systematic review and meta-analysis.

SAMPLE POPULATION

Comparative studies with gonadectomized and entire dogs, with CrCLD as an outcome measure.

METHODS

A systematic search of the primary and gray literature was performed. The effect size of the outcome measure was defined as the OR and 95% CI. Subgroup analysis was performed with sex, breed, and age at gonadectomy. A pooled OR (95% CI) was generated from meta-analysis of relevant studies. Certainty in the body of evidence was rated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework.

RESULTS

The literature search yielded 1398 results and 24 relevant studies were included for synthesis. Gonadectomized female (pooled OR = 2.293, 95% CI = 1.768-2.945) and male (pooled OR = 2.117, 95% CI = 1.665-2.691) dogs were both at increased odds of developing CrCLD in comparison with entire female and male dogs, respectively. Subgroup analysis showed that gonadectomy at 1 year or less was consistently associated with an increase in odds of developing CrCLD in both sexes. Overall certainty in the evidence was rated as moderate. All included studies were observational and no controlled trials were available.

CONCLUSION

In data with moderate certainty, gonadectomy is associated with increased odds of developing CrCLD in both sexes, particularly in dogs gonadectomized at 1 year of age or less.

CLINICAL SIGNIFICANCE

This study provides an estimate of the true effect size of gonadectomy on the odds of developing CrCLD, which may be useful for clinical decision making surrounding gonadectomy and the timing of gonadectomy.

Tobacco smoking and its impact on pain intensity of temporomandibular disorders: A systematic review and metanalysis

BACKGROUND

Temporomandibular disorders (TMDs) encompass a spectrum of orofacial conditions characterised by pain and dysfunction in the temporomandibular joint and surrounding structures. Tobacco smoking has been posited as a potential factor influencing the prevalence and intensity of TMD. However, the nature and extent of this relationship remain unclear due to variations in study outcomes. This systematic review aimed to consolidate existing research findings to elucidate the association between tobacco smoking and TMD pain intensity.

METHODS

A comprehensive search of electronic databases was conducted to identify relevant studies published up to June 2023. Studies investigating the relationship between tobacco smoking and TMD pain were included. Data extraction was conducted by two reviewers. Quality assessment was performed using the New Castle-Ottawa scale. Review Manager 5.4 was used to quantitatively analyse the results.

RESULTS

The review included four studies employing similar TMD assessment techniques. All studies reported elevated TMD pain intensity among tobacco users, with non-smokers exhibiting lower pain intensity. The quality of the included studies was good. Meta-analytic results showed that TMD pain intensity was higher in the smokers group compared to the non-smokers group, with a weighted mean difference (WMD) of 0.65 (BPM) (95% CI: [0.10, 1.19], p = .02).

CONCLUSION

This systematic review provides a comprehensive synthesis of the existing literature on tobacco smoking and TMD symptoms. The findings underscore the multifaceted nature of the relationship between smoking and TMD pain, highlighting its clinical relevance and the need for tailored interventions. Further research is warranted to elucidate underlying mechanisms and potential moderating factors, contributing to a more nuanced understanding of this complex association.

Multidomain Cognitive Tele-Neurorehabilitation Training in Long-Term Post-Stroke Patients: An RCT Study

PURPOSE

Over the past decade, tele-neurorehabilitation (TNR) has emerged as a vital and effective tool for delivering continuous care to stroke patients, playing a key role in enhancing functional recovery and ensuring consistent access to rehabilitation services. In the field of TNR, various protocols are utilized to ensure effective cognitive stimulation at home. Recent preliminary studies highlight the employment of multidomain cognitive interventions, which would seem to induce more stable and relevant cognitive recovery in stroke patients. A randomized controlled trial (RCT) study was conducted to compare the effectiveness of a TNR multidomain cognitive approach to conventional face-to-face cognitive treatment.

METHODS

A total of 30 patients with stroke were equally enrolled and randomly assigned to the experimental and control groups. In the experimental group, patients received sessions of home-based cognitive virtual reality rehabilitation system (VRRS) training. The control group underwent traditional face-to-face cognitive multidomain treatment at the hospital. The therapy was given for one hour every day for four weeks in both groups. Specific cognitive domains, including memory, praxis skills, executive functions, and speech therapy, were stimulated in the procedure. Neuropsychological evaluations were performed at three timepoints: at baseline (T0), at the end of TNR (T1), and six months later (T2).

RESULTS

The TNR group demonstrated significant improvements in working memory and language abilities, as well as in depressive symptoms and caregiver burden, with an average decrease of 2.07. Most of this improvement persisted 6 months after treatment. The group that received face-to-face cognitive treatment showed improvements (not persisting at T2) after treatment in a task measuring constructive apraxia and alternating attention with the cognitive skill of set-shifting.

CONCLUSIONS

According to our findings, multidomain cognitive TNR may be useful in enhancing cognitive outcomes in stroke populations (even six months after treatment concludes). TNR may also be a viable way to deliver these interventions since it boosts people's motivation to train and, consequently, their adherence to treatment while also having a positive effect on caregivers' distress management.

A systematic review of total IgE reference intervals - A 2024 update

BACKGROUND

Total IgE (tIgE) is a frequently requested analyte in patients presenting with symptoms of atopy. Although tIgE has limited clinical utility in the diagnosis of atopic diseases, it is still important that appropriate reference intervals are provided to the intepreting clinician. Concerns have recently been raised whether laboratories may be using outdated tIgE reference intervals. The aim of this study was therefore to perform the first systematic literature review of tIgE reference intervals to aid laboratories in choosing appropriate sources.

METHODS

A search was performed in MEDLINE, Embase and the Cochrane Library from time of inception to July 2024. Eligible studies had to provide an estimate of paediatric and/or adult tIgE reference intervals using current generation immunoassays. The methodology followed PRISMA guidelines, and the study protocol was registered in the PROSPERO database (CRD42023396441).

RESULTS

A total of 1667 records were screened of which 20 studies remained after full text review. The studies included 23 910 individuals and covered 18 countries. Upper reference limits varied significantly, with participant selection (inclusion or exclusion of in vitro confirmed specific IgE sensitised individuals) and statistical methods identified as the most important factors influencing the upper reference limit.

CONCLUSION

This review emphasises the need for laboratories to carefully evaluate the participant selection criteria and employed statistical methods whilst determining which tIgE reference intervals are the most appropriate to report to clinicians. Further efforts must also be made to harmonise and improve the reporting of tIgE reference interval studies.

Conservative management of placenta accreta spectrum is associated with improved surgical outcomes compared to cesarean hysterectomy: a systematic review and meta-analysis

OBJECTIVE

To compare maternal and surgical outcomes between patients with placenta accreta spectrum who underwent conservative management and those who underwent cesarean hysterectomy.

DATA SOURCES

We performed a systematic search in PubMed, Embase, and Web of Science from inception up to June 2, 2024.

STUDY ELIGIBILITY CRITERIA

Studies comparing clinical outcomes among patients with placenta accreta spectrum undergoing conservative management vs cesarean hysterectomy were included. Conservative management was defined as leaving the placenta in situ and local myometrial resection.

STUDY APPRAISAL AND SYNTHESIS METHODS

A random-effects model was used to pool the mean differences or odds ratios and the corresponding 95% confidence intervals. Heterogeneity was assessed using the I2 statistic.

RESULTS

The meta-analysis included 16 studies, with a total of 2300 women diagnosed with placenta accreta spectrum. Of this pooled sample, 1072 patients underwent cesarean hysterectomy and 1228 were managed conservatively. In pregnancies affected by placenta accreta spectrum, cesarean hysterectomy was associated with significantly higher estimated blood loss compared to placenta in situ (mean difference 973.5 mL, 95% confidence interval 615.4-1331.7, 95% prediction interval [PI] -50.2 to 1997.2, P<.001) and local resection (mean difference 739.7 mL, 95% confidence interval 287.7-1191.7, 95% PI -911.5 to 2390.9, P<.001). Additionally, cesarean hysterectomy resulted in more intraoperative transfused red blood cell units than the local resection (mean difference 1.54 units, 95% confidence interval 1.06-2.01, 95% PI 0.27-2.81, P=.001) but had similar rates as compared to placenta in situ group (mean difference 0.72 units, 95% confidence interval -0.21 to 1.64, 95% PI -2.21 to 3.64, P=.065). The risk of genitourinary injury was significantly higher for cesarean hysterectomy compared to both placenta left in situ (odds ratio 3.79, 95% confidence interval 1.88-7.61, 95% PI 1.52-9.46, P<.001) and local resection (odds ratio 4.11, 95% confidence interval 2.57-6.56, 95% PI 2.34-7.22, P<.001). Patients undergoing cesarean hysterectomy, as compared to placenta in situ group, were more likely to be admitted to intensive care unit (odds ratio 7.98, 95% confidence interval 2.23-28.51, 95% PI 0.34-188.50, P<0.001); however, there was no significant difference between cesarean hysterectomy and local resection group in terms of intensive care unit admission. There were no significant differences between cesarean hysterectomy and conservative approaches regarding the risk of gastrointestinal injury and thromboembolic events.

CONCLUSION

This meta-analysis strengthens the evidence supporting conservative management for pregnancies with placenta accreta spectrum, demonstrating that it is associated with reduced surgical morbidity and may offer an effective alternative to cesarean hysterectomy, particularly for patients seeking fertility preservation. However, further research, including randomized controlled trials and longitudinal studies, is necessary to more definitively evaluate conservative management approaches for pregnancies with placenta accreta spectrum and assess long-term clinical outcomes after conservative management.

Effects of Electronic Cigarettes on Periodontal Health: A Systematic Review and Meta-Analysis

OBJECTIVES

The use of electronic cigarettes "e-cigarettes," or vaping is growing in popularity, especially among adolescents and young adults. While the effects of cigarette smoking on oral health are well-established, the exact impact that e-cigarettes may have on dental tissues is still uncertain. The aim of the current review was to summarize evidence related to the effect of vaping on the periodontal health status of e-cigarette users.

METHODS

A comprehensive electronic search was performed using PubMed, Web of Science, and Scopus databases, until January 31st, 2024. Two independent reviewers participated in the screening of studies, data extraction, and assessment of the included studies. Any disagreements were resolved by a third reviewer the quality assessment was done using the Newcastle-Ottawa Scale to assess the risk of bias. A frequentist meta-analysis was performed using R Statistical Software. The random effects model was adopted. Data were described as mean difference (MD) and 95% confidence interval (CI). A p-value of ≤ .05 was deemed statistically significant.

RESULTS

Ten studies met the eligibility criteria. Overall, the findings were consistent, with most studies showing that e-cigarette users are at greater risk of periodontal disease than nonsmokers, but that they have a lower risk than cigarette smokers. Pooling results showed lower mean probing depth (PD) among nonsmokers than e-smokers (MD: -1.91; 95% CI: [-3.36: -0.47]; p-value = .01) while it was higher among cigarette smokers in participants with periodontitis (MD:0.43; 95%CI: [0.08:0.79]; p-value = .02). Compared to e-smoking, nonsmokers had lower PI (MD: -20.63; 95%CI: [-28.04: -13.21]; p-value < .001) while cigarette smokers had higher PI (MD: 4.88; 95% CI: [-1.52:11.29]; p-value = .135). Among participants with periodontitis, only cigarette smokers had significantly higher PI (MD: 4.53; 95%CI: [1.94:7.13]; p-value < .001).

CONCLUSION

Based on the current analysis, conventional cigarette smoking is the most detrimental to periodontal health among the groups compared in all included studies. This indicates that traditional cigarettes have a more severe impact on periodontal tissues than do e-cigarettes. The data suggest a gradient of risk where nonsmokers have the lowest risk, e-cigarette users have a moderate risk, and cigarette smokers have the highest risk for periodontal health issues.

The Impact of Sinus Surgery for Chronic Rhinosinusitis on Concomitant Depression and Anxiety Symptoms: A Systematic Review and Meta-analysis

BACKGROUND

Both anxiety and depression are prevalent among patients with chronic rhinosinusitis (CRS) and associated with poorer outcomes following treatment for CRS. However, the impact of treatment on CRS on mental health remains uncertain. Therefore, this study seeks to evaluate if surgical intervention for CRS may alleviate comorbid depression and anxiety.

METHODS

PubMed, Embase, and Scopus databases were searched for retrospective and prospective cohort studies, cross-sectional studies, and randomized controlled trials relating to CRS treatment using sinus surgery from inception to April 30, 2024, using the Population, Intervention, Comparison, and Outcomes (PICO) framework. Three blinded reviewers selected observational studies and randomized controlled trials investigating levels of depression and anxiety pre- and post-surgical treatment of CRS. Eleven studies comprising 3067 patients were included, of which five studies were quantitatively analyzed. After which, data were extracted from included articles into a structured proforma and the Newcastle-Ottawa Scale was used to evaluate study bias, following Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines and a PROSPERO-registered protocol (CRD42022351855). Meta-analyses of the ratio of means were conducted in a random-effects model.

RESULTS

Overall, sinus surgery was associated with significant improvement in test scores of depression (ratio of means (ROM) = 1.47, 95% confidence interval [CI] = 1.03‒2.10), anxiety (ROM = 1.10, 95% CI = 0.81‒1.49), and quality of life markers, which are closely correlated to mental health outcomes.

CONCLUSIONS

Sinus surgery for CRS may improve mental health outcomes (both depression and anxiety) for patients.

Prevalence and associated factors of malaria among the displaced population in refugee camps in Africa: a systematic review and meta-analysis

BACKGROUND

The increased occurrence of malaria among Africa's displaced communities poses a new humanitarian problem. Understanding malaria epidemiology among the displaced population in African refugee camps is a vital step for implementing effective malaria control and elimination measures. As a result, this study aimed to generate comprehensive and conclusive data from diverse investigations undertaken in Africa.

METHODS

This review adhered to PRISMA standards, involving searches across electronic data bases such as Google Scholar, PubMed, Web of Science, Scopus, and Science Direct. In addition, grey literature was retrieved from several professional associations. The quality of selected studies was evaluated using the Newcastle-Ottawa Quality Assessment Scale. Data extraction was executed using Microsoft Excel, and the meta-analysis was performed with STATA 14 software. A random-effects model was used to estimate the pooled prevalence and associated factors of malaria. Meta-regression and subgroup analysis were used to identify heterogeneity, while funnel plots and Egger's statistical tests assessed the publication bias. Furthermore, a sensitivity analysis was performed.

RESULTS

The overall random-effects pooled prevalence of malaria infection (comprising symptomatic and asymptomatic cases) across all included studies was 35.93% (95% CI 24.71-47.15). This study showed a high level of heterogeneity between studies (I2 = 97.1; P < 0.001). Of the identified Plasmodium species, Plasmodium falciparum constituted 99.3%. The frost plot indicated that the overall prevalence of P. falciparum was 34.94% (95% CI 24.34-45.53). Subgroup analysis revealed significant variation (P < 0.001) in malaria prevalence between asymptomatic and symptomatic cases, with a prevalence of 4.39% (95% CI 2.57-6.21) and 45.10% (95% CI 27.28-62.92), respectively. Lack of insecticide-treated mosquito net utilization (AOR 2.43; 95% CI 1.01-5.88) and living near mosquito breeding sites (AOR 2.76, 95% CI 1.56-4.87) were risk factors of malaria.

CONCLUSION

This study determined that the pooled prevalence of malaria among displaced individuals in refugee camps was high and exhibited variations across different population groups. This signifying there is still a need to improve and recheck existing malaria prevention and control strategies to establish an effective malaria control and elimination programme in Africa.
