Evaluating the association of childhood sexual abuse with the development of irritable bowel syndrome later in life: A systematic review.

Objective: To review available medical literature to elucidate the association between childhood sexual abuse and the development of irritable bowel syndrome later in life. METHODS: This systematic review was conducted from January to August 2022 and comprised a literature search on Medline (via PubMed), Scopus, Embase, Web of Science, and Google Scholar databases for relevant studies published between 2001 and 2021. The Newcastle-Ottawa scale was used to determine the quality of the studies. Data on the prevalence of irritable bowel syndrome were meta-analysed using a Mantel-Haenszel random-effects model in RevMan 5.4.1. RESULTS: Of the 7 observational studies analyzed in detail, 5 (71.4%) had a case-control design, and 2 (28.6%) were crosssectional studies. Overall, there were 3156 subjects. The prevalence of irritable bowel syndrome in the childhood sexual abuse group was 51.86% (334/644), while it was 36.74% (923/2512) in the non-childhood sexual abuse group. The pooled odds ratio, indicating the association between childhood sexual abuse and irritable bowel syndrome, was 1.87 (95% confidence interval: 1.56-2.26). The study quality was rated as good in 3 (42.8%) cases, fair in 3 (42.8%), and poor in 1 (14.3%). Conclusion: Childhood sexual abuse was found to be significantly associated with the development of irritable bowel syndrome later in life, further strengthening the argument that childhood sexual abuse can lead to long-term detriments extending into adulthood. However, there was no existing literature found that stratified other aspects of irritable bowel syndrome, including symptom severity and childhood sexual abuse being the exclusive cause of irritable bowel syndrome.

Efficacy of Intravascular Imaging-Guided Drug-Eluting Stent Implantation: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Intravascular imaging (IVI) namely intravascular ultrasound (IVUS) and optical coherence tomography (OCT), presents as a promising imaging modality for drug-eluting stent (DES) implantation compared to the gold-standard conventional two-dimensional angiography. IVI provides detailed information on vessel lumen, lesion length, and degree of calcification. For this purpose, we conducted a meta-analysis by pooling recently conducted randomized control trials (RCTs) to compare IVI with angiography for DES implantation. Scopus and MEDLINE were searched till May 2023 for RCTs comparing IVI with traditional angiography-guided stent implantation in coronary artery disease patients undergoing percutaneous coronary intervention. The primary outcome of interest was target-lesion revascularization (TLR). Secondary outcomes included target vessel revascularization (TVR), all-cause mortality, and major adverse cardiovascular events (MACE). A random-effects meta-analysis with metaregression was performed to derive risk ratios with corresponding 95% CIs from dichotomous data. Fourteen RCTs with a total of 8946 CAD patients (IVI 4751 vs angiography 4195; mean age 61.7 years) and a median follow-up of 15 months (12-24.3) were included. IVI was associated with significantly reduced TLR (RR 0.63 [0.49, 0.79]) vs conventional angiography. Similarly, TVR incidence (RR 0.66 [0.53, 0.83]), and MACE (RR 0.69 [0.58, 0.78]) were also significantly decreased with IVI vs conventional angiography for PCI. However, no significant difference was observed in all-cause mortality between the 2 imaging modalities (RR 0.85 [0.63, 1.15]). Metaregression analysis showed no significant impact of follow-up duration, baseline comorbidities such as hypertension, smoking status, previous MI, and stent length on TLR incidence. IVI was associated with improved clinical outcomes in terms of reduced TLR, TVR, and MACE incidence when compared with traditional angiography in CAD patients for stent implantation.

Association of neutrophil-to-lymphocyte ratio and hemodialysis access failure in patients with end stage renal disease: A systematic review and meta-analysis.

This systematic review and meta-analysis aimed to assess the association of neutrophil-to-lymphocyte ratio (NLR) with an elevated risk of vascular access failure in end-stage renal disease (ESRD) patients undergoing hemodialysis. A comprehensive database search of MEDLINE (via PubMed), Scopus, and Cochrane Central was performed. Studies reporting the values of NLR in both functional and non-functional AVF groups in ESRD patients were selected. Quality assessment was performed using the Modified Newcastle-Ottawa scale for observational studies. Meta-analysis was performed using an inverse variance random effects model. Seven observational studies met the inclusion criteria, including 1313 participants with 554 cases and 759 controls. Pooled results showed significantly high NLR levels in patients with non-functional arteriovenous fistula (AVF) compared to functional AVF (SMD = 1.19, 95% CI = 0.74-1.65, p < 0.001). Subgroup analysis confirmed the consistency of the association between NLR and AVF failure across study design (SMD = 1.76, 95% CI = 0.78-2.73, p = 0.0004 in prospective vs SMD = 0.87, 95% CI = 0.42-1.32, p = 0.0001 in retrospective studies), etiology (SMD = 1.63, 95% CI = 0.75-2.52, p = 0.0003 in stenosis or thrombosis; and SMD = 0.80, 95% CI = 0.27-1.34, p = 0.003 in failure to mature of AVF), and NLR measurement timing (SMD = 0.98, 95% CI = 0.42-1.54, p = 0.0006 in preoperative vs SMD = 1.58, 95% CI = 0.47-2.69, p = 0.005 in postoperative NLR). The pooled odds ratio revealed high NLR values as a significant predictor of AVF failure in ESRD patients (OR = 3.91, 95% CI = 1.91-7.98, p = 0.0002). The pooled sensitivity and specificity were 89.72% (95% CI = 77.51%-95.67%) and 72.95% (95% CI = 63.82%-80.47%), respectively. The high NLR is a useful and predictive marker for AVF failure in hemodialysis patients. Future studies should prioritize larger cohort studies to validate and reinforce these observations.

Quality of life after robotic versus conventional minimally invasive cancer surgery: a systematic review and meta-analysis.

Optimizing postoperative quality of life (QoL) is an essential aspect of surgical oncology. Minimally invasive surgery (MIS) decreases surgical morbidity and improves QoL outcomes. This meta-analysis aimed to compare post-operative QoL after oncologic resections using different MIS modalities. The PubMed, Embase, Scopus, and CENTRAL databases were searched for articles that compared post-operative QoL in patients undergoing video-assisted thoracoscopic (VATS) or laparoscopic surgery (LS) versus robotic surgery (RS) for malignancy. Quality assessment was performed using the ROBINS-I and Cochrane Risk of Bias 2 (RoB-2) tools. Meta-analysis was performed using an inverse-variance random effects model. 27 studies met the inclusion criteria, including 5 randomized controlled trials (RCTs). 15 studies had a low risk of bias, while 11 had a moderate risk of bias and 1 had serious risk of bias. 8330 patients (RS: 5090, LS/VATS: 3240) from across 25 studies were included in the meta-analysis. Global QoL was significantly better after robotic surgery in the pooled analysis overall (SMD: - 0.28 [95% CI: - 0.49, - 0.08]), as well as in the prostatectomy and gastrectomy subgroups. GRADE certainty of evidence was low. Analysis of EPIC-26 subdomains also suggested greater sexual function after robotic versus laparoscopic prostatectomy. Robotic and conventional MIS approaches produce similar postoperative QoL after oncologic surgery for various tumor types, although advantages may emerge in some patient populations. Our results may assist surgeons in counseling patients who are undergoing oncologic surgery.
