Review
BACKGROUND
Aneurysms of the cerebral vasculature are relatively common, which grow unpredictably, and even small aneurysms carry a risk of rupture. Rupture of intracranial aneurysms (IA) is a catastrophic event with a high mortality rate. Pieces of evidence have demonstrated that smoking is closely related to the formation and rupture of IA. However, the biological effect of smoking cigarettes on the formation and rupture of IA is still underrepresented.
METHODS
The study protocol was prospectively registered in PROSPERO, registration number CRD42020203634. We performed a systematic search in PubMed and CNKI for studies exploring the biological effects of smoking on intracranial aneurysms published up to December 2021, and all studies were included in the analysis. The RevMan software was used for data analysis.
RESULTS
A total of 6,196 patients were included in 14 original articles in this meta-analysis. The risk of ruptured IA in the current smoking group was significantly higher than that in the non-smoking group, with statistical significance (RR = 1.23, 95% : 1.11-1.37). After heterogeneity among cohorts was removed by the sensitivity analysis, there was still a statistically significant difference in the risk of ruptured IA between the smoking and non-smoking groups (RR total = 1.26, 95% : 1.18-1.34). There was no statistically significant difference in the risk of ruptured IA between the former smoking (smoking cessation) group and the non-smoking group (RR = 1.09, 95% : 0.50-2.38). After heterogeneity among cohorts was removed by sensitivity analysis, there was still no statistically significant difference in the risk of ruptured IA between the former smoking (smoking cessation) group and the non-smoking group (RRtotal = 0.75, 95% : 0.47-1.19). The risk of the ruptured IA in the current smoking group was significantly higher than that in the former smoking (smoking cessation) group, with a statistically significant difference (RR=1.42, 95%: 1.27-1.59).
CONCLUSION
Although the biological effects of smoking on the formation and rupture of IA are unknown, this study suggests that current smoking is a risk factor for ruptured IA. Quitting smoking is very important for patients with IA.

BMJ (Clinical Research Ed.) Jul 2004To evaluate the incidence and consequences of uterine rupture in women who have had a delivery by caesarean section. (Review)
Review
OBJECTIVE
To evaluate the incidence and consequences of uterine rupture in women who have had a delivery by caesarean section.
DESIGN
Systematic review.
DATA SOURCES
Medline, HealthSTAR, Cochrane Database of Systematic Reviews, Cochrane Controlled Trials Register, National Centre for Reviews and Dissemination, reference lists, and national experts. Studies in all languages were eligible if published in full.
REVIEW METHODS
Methodological quality was evaluated for each study by using criteria from the United States Preventive Services Task Force and the National Health Service Centre for Reviews and Dissemination. Uterine rupture was categorised as asymptomatic or symptomatic.
RESULTS
We reviewed 568 full text articles to identify 71 potentially eligible studies, 21 of which were rated at least fair in quality. Compared with elective repeat caesarean delivery, trial of labour increased the risk of uterine rupture by 2.7 (95% confidence interval 0.73 to 4.73) per 1000 cases. No maternal deaths were related to rupture. For women attempting vaginal delivery, the additional risk of perinatal death from rupture of a uterine scar was 1.4 (0 to 9.8) per 10,000 and the additional risk of hysterectomy was 3.4 (0 to 12.6) per 10 000. The rates of asymptomatic uterine rupture in trial of labour and elective repeat caesarean did not differ significantly.
CONCLUSIONS
Although the literature on uterine rupture is imprecise and inconsistent, existing studies indicate that 370 (213 to 1370) elective caesarean deliveries would need to be performed to prevent one symptomatic uterine rupture.

Review
The extensor mechanism of the knee can be damaged due to various modes of injury, which, in most cases, will require urgent surgical intervention for repair. Single patellar tendon ruptures are uncommon, but simultaneous bilateral events are even rarer and have been scarcely reviewed in English literature. Research in this area is mainly confined to case series, with some literature reviews but no evidence of more substantial analysis. Therefore, this systematic review was done to analyse the existing literature on bilateral simultaneous patellar tendon ruptures and propose a systematic and standardised approach to diagnosing and managing these injuries. A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The search terms included 'bilateral patellar tendon rupture', 'bilateral', 'patellar', 'tendon' and 'rupture'. Three independent reviewers conducted searches in PubMed, OvidSP for Medline, Embase and the Cochrane Library using the same search strategy. The eligibility criteria included studies on bilateral concomitant patellar tendon rupture published in English. Bilateral simultaneous patellar tendon ruptures of traumatic and atraumatic origin in human patients were included. The study types comprised case reports and literature reviews. The key limitation of this study was the low number of patients covered by the eligible literature. Patellar tendon ruptures are a rare and scarcely documented injury, and there is a need for studies with a high level of evidence, especially regarding surgical treatment choice and methods, as well as post-operative management, which could potentially lead to improved outcomes in the management of this injury.

Meta-Analysis
BACKGROUND
Uterine rupture has a significant public health importance, contributing to 13% of maternal mortality and 74%-92% of perinatal mortality in Sub-Saharan Africa, and 36% of maternal mortality in Ethiopia. The prevalence and predictors of uterine rupture were highly variable and inconclusive across studies in the country. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence and predictor of uterine rupture in Ethiopia.
METHODS
This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 checklist. PubMed, Cochrane Library, Google Scholar, and African Journals Online databases were searched. The Newcastle- Ottawa quality assessment tool was used for critical appraisal. I2 statistic and Egger's tests were used to assess the heterogeneity and publication bias, respectively. The random-effects model was used to estimate the pooled prevalence and odds ratios with a 95% confidence interval.
RESULTS
Sixteen studies were included, with a total of 91,784 women in the meta-analysis. The pooled prevalence of uterine rupture was 2% (95% CI: 1.99, 3.01). The highest prevalence was observed in the Amhara regional state (5%) and the lowest was in Tigray region (1%). Previous cesarean delivery (OR = 9.95, 95% CI: 3.09, 32.0), lack of antenatal care visit (OR = 8.40, 95% CI: 4.5, 15.7), rural residence (OR = 4.75, 95% CI: 1.17, 19.3), grand multiparity (OR = 4.49, 95% CI: 2.83, 7.11) and obstructed labor (OR = 6.75, 95%CI: 1.92, 23.8) were predictors of uterine rupture.
CONCLUSION
Uterine rupture is still high in Ethiopia. Therefore, proper auditing on the appropriateness of cesarean section and proper labor monitoring, improving antenatal care visit, and birth preparedness and complication readiness plan are needed. Moreover, early referral and family planning utilization are the recommended interventions to reduce the burden of uterine rupture among Ethiopia women.

Review
BACKGROUND
The objective of this systematic review is to evaluate the pathogenesis, clinical course, and prognosis of patients who suffer from aneurysm rupture, leading to subdural hematoma (SDH) of the infratentorial space without associated subarachnoid hemorrhage (SAH).
METHODS
Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a literature review was conducted in PubMed and Scopus electronic databases for relevant published cases of aneurysmal SDH (AnSDH) of the infratentorial compartment without associated SAH. The presentation, treatment, clinical course, and outcome of identified cases are compiled. In addition, a patient suffering from an infratentorial SDH following aneurysm rupture is presented with an illustrative case.
RESULTS
Three articles were identified and met inclusion criteria. All cases occurred from ruptured posterior communicating artery aneurysms. All patients arrived with a Hunt and Hess classification of 2 or less. Only one case was managed with operative aneurysm clipping and hematoma evacuation while the other three cases were managed endovascularly. There were no reported postoperative complications, vasospasm, or seizures reported. All patients had a final Modified Rankin score of 3 or less at last reported follow-up.
CONCLUSION
Infratentorial AnSDH without associated SAH is an etiology rarely reported in the literature. Here, we present a case report and systematic review demonstrating a relatively benign clinical course and outcome compared to report aneurysm rupture associated with SAH or mixed SAH and SDH. Moreover, there appear to be lower rates of vasospasm and improved outcomes in patients with isolated AnSDH compared to the literature aneurysmal SAH rates.

Review
BACKGROUND
It is a common belief in medical community that lunar phases have an impact on human health. A growing body of evidence indicates that lunar phases can predict the risk to develop acute neurological and vascular disorders. The goal of present report was to present our institution data and to perform systematic review of studies examining the association of intracranial aneurysm rupture with moon phases.
METHODS
We identified all patients admitted to our department for ruptured intracranial aneurysms in a period between November, 2011 and December, 2014. Patients with a known aneurysm rupture date were included. Lunar phases were determined by dividing lunar month (29.5 days) into eight equal parts, i.e., new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. A systematic literature review was undertaken to identify studies that evaluated the association of lunar phases with the incident of intracranial aneurysm rupture.
RESULT
One hundred and eighty-six patients (62 men and 124 women, median age 56 years) were admitted to our department for treatment of ruptured intracranial aneurysms. The rate of intracranial aneurysm rupture was equally distributed across all phases of the lunar cycle (X [7; 185] = 12.280, p = 0.092). We identified three studies that evaluated the association between incident intracranial aneurysm rupture and lunar phases with a total of 1483 patients. One study from Lebanon found that the incidence rate of intracranial aneurysm rupture was statistically significantly greater during the new moon phase (25% cases), relative to the other seven lunar phases (p < 0.001). Two subsequent studies from Austria and Germany in larger patient samples (n = 717 and n = 655, respectively) did not find an association between lunar phases and intracranial aneurysm rupture (p-values of 0.84 and 0.97, respectively). When analyzing all four studies together, we did not find an association between lunar phases and incidence of intracranial aneurysm rupture (X [1668; 7] = 2.080, p = 0.955).
CONCLUSIONS
Moon phases are not associated with incidence of intracranial aneurysm rupture. Studies investigating the association of intracranial aneurysm rupture with lunar illumination defined using more sensitive approaches are encouraged.

Meta-Analysis
Immediate mobilization after repair of Achilles tendon rupture may increase the incidence of re-rupture: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Achilles tendon rupture (ATR) is a significant injury that can require surgery and can have the risk of re-rupture even after successful treatment. Consequently, to minimize this risk, it is important to have a thorough understanding of the rehabilitation protocol and the impact of different rehabilitation approaches on preventing re-rupture.
MATERIALS AND METHODS
Two independent team members searched several databases (PubMed, EMBASE, Web of Science, Cochrane Library, and CINAHL) to identify randomized controlled trials (RCTs) on operative treatment of ATR. We included articles that covered open or minimally invasive surgery for ATR, with a detailed rehabilitation protocol and reports of re-rupture. The study protocol has been registered at PROSPERO and has been reported in the line with PRISMA Guidelines, Supplemental Digital Content 1, http://links.lww.com/JS9/C85 , Supplemental Digital Content 2, http://links.lww.com/JS9/C86 and assessed using AMSTAR Tool, Supplemental Digital Content 3, http://links.lww.com/JS9/C87 .
RESULTS
A total of 43 RCTs were eligible for the meta-analysis, encompassing a combined cohort of 2553 patients. Overall, the postoperative incidence of ATR patients developing re-rupture was 3.15% (95% CI: 2.26-4.17; I2 =44.48%). Early immobilization group patients who had ATR had a 4.07% (95% CI: 1.76-7.27; I2 =51.20%) postoperative incidence of re-rupture; Early immobilization + active range of motion (AROM) group had an incidence of 5.95% (95% CI: 2.91-9.99; I2 =0.00%); Early immobilization + weight-bearing group had an incidence of 3.49% (95% CI: 1.96-5.43; I2 =20.06%); Early weight-bearing + AROM group had an incidence of 3.61% (95% CI: 1.00-7.73; I2 =64.60%); Accelerated rehabilitation (immobilization) group had an incidence of 2.18% (95% CI: 1.11-3.59; I2 =21.56%); Accelerated rehabilitation (non-immobilization) group had a rate of 1.36% (95% CI: 0.12-3.90; I2 =0.00%). Additionally, patients in the immediate AROM group had a postoperative re-rupture incidence of 3.92% (95% CI: 1.76-6.89; I2 =33.24%); Non-immediate AROM group had an incidence of 2.45% (95% CI: 1.25-4.03; I2 =22.09%).
CONCLUSIONS
This meta-analysis suggests the use of accelerated rehabilitation intervention in early postoperative rehabilitation of the Achilles tendon. However, for early ankle joint mobilization, it is recommended to apply after one to two weeks of immobilization.

Meta-Analysis Review
Systematic review and meta-analysis of the growth and rupture rates of small abdominal aortic aneurysms: implications for surveillance intervals and their cost-effectiveness.
BACKGROUND
Small abdominal aortic aneurysms (AAAs; 3.0-5.4 cm in diameter) are usually asymptomatic and managed by regular ultrasound surveillance until they grow to a diameter threshold (commonly 5.5 cm) at which surgical intervention is considered. The choice of appropriate surveillance intervals is governed by the growth and rupture rates of small AAAs, as well as their relative cost-effectiveness.
OBJECTIVES
The aim of this series of studies was to inform the evidence base for small AAA surveillance strategies. This was achieved by literature review, collation and analysis of individual patient data, a focus group and health economic modelling.
DATA SOURCES
We undertook systematic literature reviews of growth rates and rupture rates of small AAAs. The databases MEDLINE, EMBASE on OvidSP, Cochrane Central Register of Controlled Trials 2009 Issue 4, ClinicalTrials.gov, and controlled-trials.com were searched from inception up until the end of 2009. We also obtained individual data on 15,475 patients from 18 surveillance studies.
REVIEW METHODS
Systematic reviews of publications identified 15 studies providing small AAA growth rates, and 14 studies with small AAA rupture rates, up to December 2009 (later updated to September 2012). We developed statistical methods to analyse individual surveillance data, including the effects of patient characteristics, to inform the choice of surveillance intervals and provide inputs for health economic modelling. We updated an existing health economic model of AAA screening to address the cost-effectiveness of different surveillance intervals.
RESULTS
In the literature reviews, the mean growth rate was 2.3 mm/year and the reported rupture rates varied between 0 and 1.6 ruptures per 100 person-years. Growth rates increased markedly with aneurysm diameter, but insufficient detail was available to guide surveillance intervals. Based on individual surveillance data, for each 0.5-cm increase in AAA diameter, growth rates increased by about 0.5 mm/year and rupture rates doubled. To control the risk of exceeding 5.5 cm to below 10% in men, on average a 7-year surveillance interval is sufficient for a 3.0-cm aneurysm, whereas an 8-month interval is necessary for a 5.0-cm aneurysm. To control the risk of rupture to below 1%, the corresponding estimated surveillance intervals are 9 years and 17 months. Average growth rates were higher in smokers (by 0.35 mm/year) and lower in patients with diabetes (by 0.51 mm/year). Rupture rates were almost fourfold higher in women than men, doubled in current smokers and increased with higher blood pressure. Increasing the surveillance interval from 1 to 2 years for the smallest aneurysms (3.0-4.4 cm) decreased costs and led to a positive net benefit. For the larger aneurysms (4.5-5.4 cm), increasing surveillance intervals from 3 to 6 months led to equivalent cost-effectiveness.
LIMITATIONS
There were no clear reasons why the growth rates varied substantially between studies. Uniform diagnostic criteria for rupture were not available. The long-term cost-effectiveness results may be susceptible to the modelling assumptions made.
CONCLUSIONS
Surveillance intervals of several years are clinically acceptable for men with AAAs in the range 3.0-4.0 cm. Intervals of around 1 year are suitable for 4.0-4.9-cm AAAs, whereas intervals of 6 months would be acceptable for 5.0-5.4-cm AAAs. These intervals are longer than those currently employed in the UK AAA screening programmes. Lengthening surveillance intervals for the smallest aneurysms was also shown to be cost-effective. Future work should focus on optimising surveillance intervals for women, studying whether or not the threshold for surgery should depend on patient characteristics, evaluating the usefulness of surveillance for those with aortic diameters of 2.5-2.9 cm, and developing interventions that may reduce the growth or rupture rates of small AAAs.

Review
BACKGROUND
Premature rupture of the membrane is a serious public health problem, especially in low- and middle-income countries with significant maternal and perinatal morbidity and mortality. Despite its substantial contributions to feto-maternal complications, the burden of premature rupture of the membrane was not systematically analyzed in Ethiopia. Hence, this review aimed to identify the burden of premature rupture of the membrane and associated factors among pregnant women in Ethiopia.
METHODS
PubMed/Medline, Scopus, and African journal online databases and Google Scholar were searched for articles published in the English language. Independent review authors selected and screened studies. Appraisal for methodological quality of studies was conducted using the Joanna Briggs Institute assessment checklist. RevMan 5.3 software was used for meta-analysis. The statistical significance and Egger's test were used to assess heterogeneity and publication bias, respectively.
RESULTS
The pooled prevalence of premature rupture of the membrane among pregnant women in Ethiopia was 9.2% (95% confidence interval = 5.0, 16.4). Factors significantly associated with premature rupture of the membrane were no antenatal care visit (odds ratio = 2.87, confidence interval = 1.34, 6.14), history of premature rupture of the membrane (odds ratio = 4.09, 95% confidence interval = 2.82, 5.91), history of abortion (odds ratio = 3.13, confidence interval = 1.63, 6.01), abnormal vaginal discharge (odds ratio = 6.78, confidence interval = 4.11, 11.16), and urinary tract infection (odds ratio = 3.04, confidence interval = 1.21, 7.63).
CONCLUSION
Nearly one in ten pregnancies in Ethiopia encounters premature rupture of the membrane complications. The finding highlights improving antenatal care utilization, thus preventing or treating urinary and reproductive tract infections, and tailored interventions for pregnant women with a history of premature rupture of the membrane or abortion contribute to reduced premature rupture of the membrane.

INTRODUCTION
Prelabour rupture of membranes at term affects approximately 10% of women during pregnancy, and it is often associated with a higher risk of infection than when the membranes are intact. In an attempt to control the risk of infection, two main approaches have been used most widely in clinical practice: induction of labour (IOL) soon after the rupture of membranes, also called active management (AM), and watchful waiting for the spontaneous onset of labour, also called expectant management (EM). In addition, previous studies have demonstrated that vaginal examinations increase the risk of chorioamnionitis. However, the effect of vaginal examinations in the context of prelabour rupture of membranes have not been researched to the same extent.
METHODS
This systematic review analyses and critiques the latest research on the management of term prelabour rupture of membranes, including the effect of vaginal examinations during labour, with a focus on the outcomes of both normal birth, and chorioamnionitis. Due to its complexity, three research questions were identified using the PICO diagram, and subsequently, the results from these searches were combined. The systematic review aimed to identify randomised controlled trials (RCTs) and observational studies that compared active vs expectant management, included number of vaginal examinations and had chorioamnionitis and/or normal birth as outcomes. The following databases were used: MEDLINE, EMBASE, Maternity and Infant care, LILACS, CINAHL and the Cochrane Central Register of Controlled trials. Quality was assessed using a tool developed especifically for this study that included questions from CASP and the Cochrane risk of bias tool. Due to the high degree of heterogeneity meta-analysis was not deemed appropriate. Therefore, simple narrative analysis was carried out.
RESULTS
Thirty-two studies met the inclusion criteria, of which 27 were RCTs and 5 observational studies. The overall quality of the studies wasn't high, 15 out of the 32 studies were deemed to be low quality and only 17 out of 32 studies were deemed to be of intermediate quality. The systematic review revealed that the management of term prelabour rupture of membranes continues to be controversial. Previous research has compared active management (Induction of labour shortly after the rupture of membrane) against expectant management (watchful waiting for the spontaneous onset of labour). Although previous studies have demonstrated that vaginal examinations increase the risk of chorioamnionitis, no prospective studies have included an intervention to reduce the number of vaginal examinations.
CONCLUSION
A RCT assessing the consequences of active management and expectant management as well as the effect of vaginal examinations during labour for term prelabour rupture of membranes is necessary.
