Review
OBJECTIVE
This review aimed to assess the evidence available in the literature about the protocols for using peanut ball (PB) in women during labour and delivery.
DATA SOURCES
A systematic search was carried out by 2 independent researchers in the PubMed/MedLine, Web of Science, Embase, Cochrane and Scopus databases, and the reference lists were scanned for additional articles.
STUDY SELECTION
Search terms employed were selected from MeSH (Medical Subject Headings) and DeCS (Descriptors in Health Sciences) and combined in each database: "Pregnant Women" AND "Peanut Ball", "Peanut Ball" AND "Labor, Obstetric", as well as "Peanut Ball" AND "Parturition". There were no limits regarding the publication period or language. Studies that answered the following question were included: What are the protocols for the use of the PB in women during labour and childbirth described in the literature? Secondary studies were excluded. Disagreements were resolved by a third researcher.
DATA EXTRACTION
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement guided this review. The authors prepared a standardized data extraction sheet to extract data and used the Mendeley software to organize the analyzed studies.
DATA SYNTHESIS
Ten studies made up the final sample of this review. Eight articles presented the protocol for using the PB: 2 studies included it after epidural analgesia and removed it at complete cervical dilation and effacement; 4 addressed the frequency of position changes during labour; and 3 reported data on maternal positions that were adopted. Five studies showed lower rates of cesarean delivery, and 2 reported that PB reduces the length of labour. Only 1 article associated the use of PB with the reduction of instrumental deliveries and perineal lacerations. One study showed a positive evaluation of parturients regarding the use of PB.
CONCLUSION
PB was associated with a reduction in cesarean and instrumental deliveries, and the length of labour. Despite its benefits, there is no standardized protocol for the use of PB, preventing it from predicting outcomes with its use.

Meta-Analysis Review
OBJECTIVE
The current meta-analysis was designed to investigate the impact of Hyoscine N-butyl bromide (HBB) rectal on labour duration and the rate of cervical dilatation by consolidating the available data.
METHODS
The search of Medline through the PubMed interface, Scopus, ScienceDirect, and the Cochrane Central Register of Controlled Trials (CENTRAL) was performed for original articles concerning the effects of HBB rectal on the duration of labour published prior to 26 June 2023. Search terms were based on Medical Subject Headings without time and language restrictions. They included: Hyoscine, Scopolamine, HBB, Buscopan, Buscolysin, Buscapine, rectal, suppository, childbirth, delivery, active phase, second stage, cervical dilatation, labour, labour, and duration of labour. The Comprehensive Meta-Analysis V3 software was used for all analyses.
RESULTS
Five randomized control trials and 1 non-randomized study involving 1310 women were included in the systematic review. Two studies were excluded from the meta-analysis because of heterogeneous interventions and a lack of mean and SD results. The results determined that HBB rectal administration significantly decreased the duration of the active phase (pooled mean difference -193.893; 95% CI -229.173 to -158.613, P < 0.001; I squares = 90.097%) and second stage of labour (pooled mean difference -2.911; 95% CI -5.486 to -0.336, P = 0.027; I squares = 90.097%). Also, the cervical dilatation rate in the active phase of labour was 0.981 cm/h higher than in the control group (I = 0.0%; P < 0.001).
CONCLUSION
This meta-analysis found that HBB rectal administration shortened the active labour phase and second stage and increased the rate of cervix dilatation; consequently, it can be used as a cost-effective intervention for low-risk pregnant women during labour. However, our findings also suggest that more robust clinical trials are required to generate evidence and confirm the use of HBB during labour for clinical practice guidelines.

Review
BACKGROUND
Ivabradine improves cardiac function in patients with heart failure, but its effect on dilated cardiomyopathy (DCM) remains unclear. We performed a systematic review and meta-analysis to study the efficacy and potential mechanisms of ivabradine's effect on cardiac function and prognosis in patients with DCM.
METHODS
We searched PubMed, Cochrane Library, Embase, Web of Science, and four registers through September 28, 2022. All controlled trials of ivabradine for the treatment of DCM with congestive heart failure were included. Articles were limited to English, with the full text and necessary data available. We performed random- or fixed effects meta-analyses for all included outcome measures and compared the effect sizes for outcomes in patients treated with and without ivabradine. The quality of the studies was assessed using the Cochrane risk-of-bias tool for randomized trials (RoB2.0).
FINDINGS
Five trials with 357 participants were included. The pooled risk ratio was 0.48 [95% confidence interval (CI) (0.18, 1.25)] for all-cause mortality and 0.38 [95% CI (0.12, 1.23)] for cardiac mortality. The pooled mean difference was -15.95 [95% CI (-19.97, -11.92)] for resting heart rate, 3.96 [95% CI (0.99, 6.93)] for systolic blood pressure, 2.93 [95% CI (2.09, 3.77)] for left ventricular ejection fraction, -5.90 [95% CI (-9.36, -2.44)] for left ventricular end-systolic diameter, -3.41 [95% CI (-5.24, -1.58)] for left ventricular end-diastolic diameter, -0.81 [95% CI (-1.00, -0.62)] for left ventricular end-systolic volume, -0.67 [95% CI (-0.86, -0.48)] for left ventricular end-diastolic volume, -11.01 [95% CI (-19.66, -2.35)] for Minnesota Living with Heart Failure score, and -0.52 [95% CI (-0.73, -0.31)] for New York Heart Association class.
INTERPRETATION
Ivabradine reduces heart rate and ventricular volume, and improves cardiac function in patients with DCM, but showed no significant effect on the prognosis of patients.

Review
OBJECTIVES
Internal jugular vein phlebectasia (IJVP) is a rare type of vascular abnormality that causes dilatation of internal jugular vein in the neck. There is presently no consensus on the most effective method of treatment for this condition, that is commonly seen in children. We conducted a systematic review of the literature reported till date to comprehend the key features of IJVP and its most effective therapeutic modalities.
METHODS
Five databases were searched until October 10, 2022 for articles of any design (including case reports) reporting IJVP in pediatric subjects. Individual patient data on demographics, clinical features of this entity and the differential diagnosis, methods of imaging, management, and outcome of illness were recorded. The quality assessment was performed using the Joanna Briggs Institute's Critical Appraisal Checklist for studies.
RESULTS
A total of 51 articles including 169 cases were retrieved and included in the analysis. Of the 169 patients, most of them were male children, and in 77% of cases right internal Juglar vein was involved. All patients had some symptoms suggestive of IJVP with most common ones being neck swelling or tenderness, and difficulty in breathing. In 90% of cases, it was observed that the neck swelling typically increases in size with Valsalva maneuver. Once jugular vein phlebectasia was clinically suspected, ultrasonography, CECT, or color Doppler flow imaging were used to confirm the diagnosis. The management of most of the cases was either conservative or surgical, and in surgery mostly ligation was performed. There have not been any cases of serious complications, therefore, according to included studies, a conservative approach is recommended with continuous monitoring. Out of the 51 studies included, most of them had low risk of bias.
CONCLUSION
Internal jugular vein phlebectasia, a rare benign condition, is most commonly found in children, and affects predominantly the right internal jugular vein. Although most patients did well with merely conservative treatment, still management of this vascular anomaly has to be on a case-by-case basis.

Meta-Analysis
BACKGROUND
Long-term physiological dysfunction in coronary/systemic vasculature may persist in individuals with Kawasaki disease even in the absence of coronary artery abnormalities. We perform a systematic review and meta-analyses of studies assessing long-term vascular function in Kawasaki disease.
METHODS
PubMed, Embase, and Web of Science databases were searched for relevant literature published till May 2021. Patients with Kawasaki disease were included as cases and healthy age/sex-matched individuals as controls. Newcastle Ottawa Scale was used to assess the study quality. Outcome measures were differences in markers of vascular function 1 year after diagnosis of Kawasaki disease. Data were analysed using Review Manager software. Comprehensive meta-analysis software was used for meta-regression. To assess the certainty of evidence, GRADE Profiler software was utilised.
RESULTS
Of 2280 citations, 49 case-control studies (comprising 2714 cases and 2118 controls) were included for data synthesis. Decreased flow-mediated dilatation [3.83, 95%CI 0.94-6.72] and increased pulse-wave velocity [39.34 cm/sec, 95%CI 20.86-57.83], arterial stiffness [0.35, 95%CI 0.11-0.59], and common carotid artery intima-media thickness were noted in patients with Kawasaki disease. No significant difference was observed for nitroglycerine-mediated dilatation and endothelial peripheral artery tonometry (endo-PAT). Significant inter-study heterogeneity was observed for flow-mediated dilatation, arterial stiffness, carotid artery intima-media thickness, and endo-PAT. The GRADE evidence was of 'very low quality' for all outcome measures except 'moderate quality' for pulse-wave velocity.
CONCLUSIONS
Evidence suggests the presence of long-term endothelial dysfunction in patients with Kawasaki disease even in the absence of coronary artery abnormalities. Avoidance of development of other cardiovascular risk factors seems prudent in patients with Kawasaki disease.

Meta-Analysis Review
This systematic review assesses the effect of menopausal hormone therapy (MHT) on cardiovascular outcomes and risk factors in postmenopausal women with cardiovascular disease (CVD). The Medline, Embase and Cochrane databases were searched from inception to December 2022 for randomized controlled trials (RCTs) and observational studies using methodology from a previous Cochrane review. Quality assessment used the Cochrane risk of bias tool and Newcastle-Ottawa scale, respectively. From 5647 studies identified, 29 (23 RCTs and six observational studies) were included. Most studies were conducted in North America or Europe and investigated oral estrogens. Participants were older with varying frequency of cardiac risk factors and underlying CVD. No significant difference was observed between MHT users and controls regarding primary outcomes of non-fatal myocardial infarction, cardiovascular death or stroke. No difference in frequency of angina, heart failure and transient ischemic attacks was observed. Inconsistent effects of MHT on angiographic progression were seen and varied with glycemic status. Estradiol had a positive effect on flow-mediated dilatation. Limited studies identified differing effects of MHT on cardiac risk factors, varying with estrogen preparation. This study confirms no benefit of MHT for secondary CVD prevention, highlighting evidence limitations and the importance of shared decision-making when managing menopausal symptoms in women with CVD.

Review
Intravenous infusion of human alpha calcitonin gene-related peptide (h-α-CGRP) has been applied to explore migraine pathogenesis and cerebral hemodynamics during the past three decades. Cumulative data implicate h-α-CGRP in regulating the vascular tone. In this systematic review, we searched PubMed and EMBASE for clinical studies investigating the vascular changes upon intravenous infusion of h-α-CGRP in humans. A total of 386 studies were screened by title and abstract. Of these, 11 studies with 61 healthy participants and 177 participants diagnosed with migraine were included. Several studies reported hemodynamic effects including flushing, palpitation, warm sensation, heart rate (HR), mean arterial blood pressure (MABP), mean blood flow velocity of middle cerebral artery (mean V), and diameter of superficial temporal artery (STA). Upon the start of h-α-CGRP infusion, 163 of 165 (99%) participants had flushing, 98 of 155 (63%) participants reported palpitation, and 160 of 165 (97%) participants reported warm sensation. HR increased with 14%-58% and MABP decreased with 7%-12%. The mean V was decreased with 9.5%-21%, and the diameter of the STA was dilated with 41%-43%. The vascular changes lasted from 20 to >120 min. Intravenous infusion of h-α-CGRP caused a universal vasodilation without any serious adverse events. The involvement of CGRP in the systemic hemodynamic raises concerns regarding long-term blockade of CGRP in migraine patients with and without cardiovascular complications.

Effect of aerobic and resistance exercise training on endothelial function in individuals with overweight and obesity: a systematic review with meta-analysis of randomized clinical trials.
The objective of this systematic review was to examine the effects of exercise training on endothelial function in individuals with overweight and obesity. Our review study included only randomized controlled trials (RCTs) involving adults (≥ 18 years of age) with body mass index (BMI) ≥ 25.0 kg/m. Our search was conducted in the electronic bases MEDLINE (PubMed), Cochrane, LILACS and EMBASE and in the gray literature. We performed random-effects analyses for effect estimates and used 95% prediction intervals (95% PI) for estimating the uncertainty of the study results. There were selected 10 RCTs involving 14 groups (n = 400). The quality assessment of studies using Cochrane risk-of-bias 2 (RoB 2) tool identified some concerns. Exercise training resulted in improved flow-mediated dilation (FMD) in individuals with overweight and obesity (p < 0.001) compared to the no-exercise control group. This effect of training modalities on FMD was seen for aerobic training (p < 0.001) but not for resistance training (p = 0.051). There was no difference in FMD in response to exercise training by BMI classification (overweight, obesity, overweight + obesity), p = 0.793. The present results are consistent with the notion that aerobic exercise training elicits favorable adaptations in endothelial function in individuals with overweight and obesity. Our findings should be interpreted with caution because of the small number of studies included in this review.

Meta-Analysis Review
OBJECTIVE
This study aimed to quantify the association between mode of operative delivery in the second stage of labor (cesarean delivery vs operative vaginal delivery) and spontaneous preterm birth in a subsequent pregnancy.
DATA SOURCES
MEDLINE, Embase, EmCare, CINAHL, the Cochrane Library, Web of Science: Core Collection, and Scopus were searched from database inception to April 1, 2023.
STUDY ELIGIBILITY CRITERIA
All retrospective cohort studies with participants who had a second-stage cesarean delivery (defined as intrapartum cesarean delivery at full cervical dilation) or operative vaginal delivery (including forceps- and/or vacuum-assisted delivery) and that reported the rate of preterm birth (either spontaneous or not specified) in subsequent pregnancy were included.
METHODS
Both a descriptive analysis and a meta-analysis were performed. A meta-analysis was performed for dichotomous data using the Mantel-Haenszel random-effects model and used the odds ratio as an effect measure with 95% confidence intervals. The risk of bias was assessed using Cochrane's 2022 Risk Of Bias In Non-randomized Studies of Exposure tool.
RESULTS
After screening 2671 articles from 7 databases, a total of 18 retrospective cohort studies encompassing 605,138 patients were included. The pooled rates of spontaneous preterm birth in a subsequent pregnancy were 6.9% (12 studies) after second-stage cesarean delivery and 2.6% (8 studies) after operative vaginal delivery. A total of 7 studies encompassing 75,460 patients compared the primary outcome of spontaneous preterm birth after second-stage cesarean delivery vs operative vaginal delivery in an index pregnancy with an odds ratio of 2.01 (95% confidence interval, 1.57-2.58) in favor of operative vaginal delivery. However, most studies did not include important confounding factors, did not address exposure misclassification because of failed operative vaginal delivery, and considered operative vaginal delivery as a homogeneous category with no distinction between forceps- and vacuum-assisted deliveries.
CONCLUSION
Although a synthesis of the existing literature suggests that the risk of spontaneous preterm birth is higher in those with a previous second-stage cesarean delivery than in those with operative vaginal delivery, the risk of bias in these studies is very high. Findings should be interpreted with caution.

OBJECTIVES
This systematic scoping review was conducted to 1) identify and describe labor curves that illustrate cervical dilatation over time; 2) map any evidence for, as well as outcomes used to evaluate the accuracy and effectiveness of the curves; and 3) identify areas in research that require further investigation.
METHODS
A three-step systematic literature search was conducted for publications up to May 2023. We searched the Medline, Maternity & Infant Care, Embase, Cochrane Library, Epistemonikos, CINAHL, Scopus, and African Index Medicus databases for studies describing labor curves, assessing their effectiveness in improving birth outcomes, or assessing their accuracy as screening or diagnostic tools. Original research articles and systematic reviews were included. We excluded studies investigating adverse birth outcomes retrospectively, and those investigating the effect of analgesia-related interventions on labor progression. Study eligibility was assessed, and data were extracted from included studies using a piloted charting form. The findings are presented according to descriptive summaries created for the included studies.
RESULTS AND IMPLICATIONS FOR RESEARCH
Of 26,073 potentially eligible studies, 108 studies were included. Seventy-three studies described labor curves, of which ten of the thirteen largest were based mainly on the United States Consortium on Safe Labor cohort. Labor curve endpoints were 10 cm cervical dilatation in 69 studies and vaginal birth in 4 studies. Labor curve accuracy was assessed in 26 studies, of which all 15 published after 1986 were from low- and middle-income countries. Recent studies of labor curve accuracy in high-income countries are lacking. The effectiveness of labor curves was assessed in 13 studies, which failed to prove the superiority of any curve. Patient-reported health and well-being is an underrepresented outcome in evaluations of labor curves. The usefulness of labor curves is still a matter of debate, as studies have failed to prove their accuracy or effectiveness.
