Project description:Background:Thrombosis is a common complication in patients with cancer. Whether thromboprophylaxis could benefit patients with cancer is unclear. The aim of this systematic review was to determine the efficacy and safety of thromboprophylaxis in patients with cancer undergoing surgery or chemotherapy. Methods:We searched the Cochrane Library, EMBASE, MEDLINE, EBSCOhost, and Web of Science for studies published before May 2018 to investigate whether thromboprophylaxis measures were more effective than a placebo in patients with cancer. Results:In total, 33 trials with 11,942 patients with cancer were identified. In patients with cancer undergoing surgery, the administration of thromboprophylaxis was associated with decreasing trends in venous thromboembolism (VTE) [relative risk (RR) 0.51, 95% confidence interval (CI) 0.32-0.81] and DVT (RR 0.53, 95% CI 0.33-0.87). In patients with cancer undergoing chemotherapy, the administration of thromboprophylaxis reduced the incidences of VTE, DVT, and pulmonary embolism compared with no thromboprophylaxis (RR 0.54, 95% CI 0.40-0.73; RR 0.47, 95% CI 0.31-0.73; RR 0.51, 95% CI 0.32-0.81, respectively). The pooled results regarding major bleeding showed no significant difference between prophylaxis and no prophylaxis in either the surgical or the chemotherapy groups (RR 2.35, 95% CI 0.74-7.52, p?=?0.1482, I2?=?0%; RR 1.30, 95% CI 0.93-1.83, p?=?0.1274, I2?=?0%, respectively). Conclusion:Thromboprophylaxis did not increase major bleeding events or the incidence of thrombocytopenia. All-cause mortality was not significantly different between those who received thromboprophylaxis and those who did not. This meta-analysis provides evidence that thromboprophylaxis can reduce the number of VTE and DVT events, with no apparent increase in the incidence of major bleeding in patients with cancer.

Project description:IntroductionVenous thromboembolism remains a significant complication following major gynecologic surgery. Evidence is lacking on whether it is beneficial to give pharmacologic thromboprophylaxis pre-operatively. The aim of this meta-analysis was to assess the role of pre-operative pharmacologic thromboprophylaxis in preventing post-operative venous thromboembolism.MethodsPubMed, EMBASE, and the Cochrane Central Register of Clinical Trials were searched to find randomized controlled, cohort, and case-control trials comparing pre-operative pharmacologic thromboprophylaxis to no prophylaxis, mechanical prophylaxis, or only post-operative pharmacologic thromboprophylaxis for open and minimally invasive major gynecologic surgery (benign and malignant conditions). Two authors independently assessed abstracts, full-text articles, and methodological quality. Data were extracted and pooled using ORs for random effects meta-analysis. Heterogeneity was explored using forest plots, Q-statistic, and I2 statistics. Planned subgroup analysis of use of sequential compression devices, equivalent versus non-equivalent post-operative prophylaxis, cancer diagnosis, and methodological quality were performed.ResultsSome 503 unique studies were found, and 16 studies (28 806 patients) were included in the systematic review. Twelve studies (14 273 patients) were included in the meta-analysis. The OR for incidence of post-operative venous thromboembolism was 0.59 (95% CI 0.39, 0.89), favoring pre-operative pharmacologic thromboembolism prophylaxis compared with no pre-operative pharmacologic prophylaxis (Q=13.80, I2=20.30). In studies where post-operative care was equivalent between groups, the OR for venous thromboembolism was 0.56 (95% CI 0.22, 1.40). Pre-operative pharmacologic prophylaxis demonstrated greatest benefit when utilized with both intra-operative and post-operative sequential compression devices (OR 0.43, 95% CI 0.30, 0.64) compared with when no sequential compression devices were utilized (OR 1.27, 95% CI 0.63, 2.56). When looking at only studies determined to be of high quality, the results no longer reached significance (OR 0.73, 95% CI 0.36, 1.46).ConclusionsPre-operative pharmacologic thromboprophylaxis decreases the odds of venous thromboembolism in the peri-operative period for major gynecologic oncology surgery by approximately 40%. It remains unclear whether this benefit is present in benign and minor procedures. Adequately powered studies are needed.

Project description:BACKGROUND:Given the sudden and unexpected nature of an emergency caesarean section (EmCS) coupled with an increased risk of psychological distress, it is particularly important to understand the psychosocial outcomes for women. The aim of this systematic literature review was to identify, collate and examine the evidence surrounding women's psychosocial outcomes of EmCS worldwide. METHODS:The electronic databases of EMBASE, PubMed, Scopus, and PsycINFO were searched between November 2017 and March 2018. To ensure articles were reflective of original and recently published research, the search criteria included peer-reviewed research articles published within the last 20 years (1998 to 2018). All study designs were included if they incorporated an examination of women's psychosocial outcomes after EmCS. Due to inherent heterogeneity of study data, extraction and synthesis of both qualitative and quantitative data pertaining to key psychosocial outcomes were organised into coherent themes and analysis was attempted. RESULTS:In total 17,189 articles were identified. Of these, 208 full text articles were assessed for eligibility. One hundred forty-nine articles were further excluded, resulting in the inclusion of 66 articles in the current systematic literature review. While meta-analyses were not possible due to the nature of the heterogeneity, key psychosocial outcomes identified that were negatively impacted by EmCS included post-traumatic stress, health-related quality of life, experiences, infant-feeding, satisfaction, and self-esteem. Post-traumatic stress was one of the most commonly examined psychosocial outcomes, with a strong consensus that EmCS contributes to both symptoms and diagnosis. CONCLUSIONS:EmCS was found to negatively impact several psychosocial outcomes for women in particular post-traumatic stress. While investment in technologies and clinical practice to minimise the number of EmCSs is crucial, further investigations are needed to develop effective strategies to prepare and support women who experience this type of birth.

Project description:OBJECTIVE:The aim of this study is to assess the odds of caesarean section (CS) for uninsured women in the USA and understand the underlying mechanisms as well as consequences of lower use. STUDY DESIGN:Systematic review and meta-analysis. DATA SOURCES:PubMed, Embase, the Cochrane Library and CINAHL from the first year of records to April 2018. ELIGIBILITY CRITERIA:We included studies that reported data to allow the calculation of ORs of CS of uninsured as compared with insured women. OUTCOMES:The prespecified primary outcome was the adjusted OR of deliveries by CS of uninsured women as compared with privately or publicly insured women. The prespecified secondary outcome was the crude OR of deliveries by CS of uninsured women as compared with insured women. RESULTS:12 articles describing 16 separate studies involving more than 8.8 million women were included in this study. We found: 0.70 times lower odds of CS in uninsured as compared with privately insured women (95% CI 0.63 to 0.78), with no relevant heterogeneity between studies (τ2=0.01); and 0.92 times lower odds for CS in uninsured as compared with publicly insured women (95% CI 0.80 to 1.07), with no relevant heterogeneity between studies (τ2=0.02). We found 0.70 times lower odds in uninsured as compared with privately and publicly insured women (95% CI 0.69 to 0.72). CONCLUSIONS:CSs are less likely to be performed in uninsured women as compared with insured women. While the higher rates for CS among privately insured women can be explained with financial incentives associated with private insurance, the lower odds among uninsured women draw attention at barriers to access for delivery care. In many regions, the rates for uninsured women are above, close or below the benchmarks for appropriate CS rates and could imply both, underuse and overuse.

Project description:BackgroundThe striking increase in caesarean section rates in middle- and high-income countries has been partly attributed to maternal request. We conducted a systematic review and meta-analysis of women's preferences for caesarean section.ObjectivesTo review the published literature on women's preferences for caesarean section.Search strategyA systematic search of MEDLINE, EMBASE, LILACS and PsychINFO was performed. References of all included articles were examined.Selection criteriaWe included studies that quantitatively evaluated women's preferences for caesarean section in any country. We excluded articles assessing health providers' preferences and qualitative studies.Data collection and analysisTwo reviewers independently screened abstracts of all identified citations, selected potentially eligible studies, and assessed their full-text versions. We conducted a meta-analysis of proportions, and a meta-regression analysis to determine variables significantly associated with caesarean section preference.Main resultsThirty-eight studies were included (n = 19,403). The overall pooled preference for caesarean section was 15.6% (95% CI 12.5-18.9). Higher preference for caesarean section was reported in women with a previous caesarean section versus women without a previous caesarean section (29.4%; 95% CI 24.4-34.8 versus 10.1%; 95% CI 7.5-13.1), and those living in a middle-income country versus a high-income country (22.1%; 95% CI 17.6-26.9 versus 11.8%; 95% CI 8.9-15.1).Authors' conclusionsOnly a minority of women in a wide variety of countries expressed a preference for caesarean delivery. Further research is needed to better estimate the contribution of women's demand to the rising caesarean section rates.

Project description:BackgroundProphylactic antibiotics reduce infectious morbidity from caesarean section. The timing of their administration, however, is a matter of controversy.ObjectivesTo examine maternal and neonatal infectious morbidity in women receiving preoperative prophylaxis compared with those receiving intraoperative administration.Search strategyMedline, Embase, Current Controlled Trials and Cochrane Central were searched from their inception dates to December 2011.Selection criteriaRandomised controlled trials of a single dose of any antibiotic comparing preoperative with intraoperative administration were selected.Data collection and analysisTrial characteristics, outcomes and quality measures, based on the Cochrane tool for risk of bias, were independently extracted. The random effect model of DerSimonian and Laird to estimate relative risks (RRs) for maternal and neonatal outcomes was used.Main resultsSix trials met the inclusion criteria, reporting on 2313 women and 2345 newborns. Preoperative administration was associated with a significant 41% reduction in the rate of endometritis compared with intraoperative administration (RR 0.59; 95% confidence interval [95% CI] 0.37-0.94; I2 0%). In the preoperative group, there were nonsignificant reductions in the rates of wound infection (RR 0.71; 95% CI 0.44-1.14; I2 0%), maternal febrile morbidity (RR 0.94; 95% CI 0.46-1.95; I2 0%), neonatal sepsis (RR 0.81; 95% CI 0.47-1.41; I2 0%), neonatal septic work-up (RR 0.93; 95% CI 0.71-1.21; I2 0%) and neonatal intensive-care unit admission (RR 0.92; 95% CI 0.65-1.28; I2 0%). There were nonsignificant increases in the rates of maternal pyelonephritis (RR 1.09; 95% CI 0.49-2.43; I2 0%) and neonatal pneumonia (RR 3.36; 95% CI 0.55-20.47; I2 0%).ConclusionsCompared with intraoperative administration, preoperative antibiotics significantly reduce the rate of endometritis. The lack of neonatal adverse effects should be cautiously interpreted given the limited power of the trials to detect such effects.

Project description:ImportanceMigraine is one of the most common neurologic disorders in children and adolescents. However, a quantitative comparison of multiple preventive pharmacologic treatments in the pediatric population is lacking.ObjectiveTo examine whether prophylactic pharmacologic treatments are more effective than placebo and whether there are differences between drugs regarding efficacy, safety, and acceptability.Data sourcesSystematic review and network meta-analysis of studies in MEDLINE, Cochrane, Embase, and PsycINFO published through July 2, 2018.Study selectionRandomized clinical trials of prophylactic pharmacologic treatments in children and adolescents diagnosed as having episodic migraine were included. Abstract, title, and full-text screening were conducted independently by 4 reviewers.Data extraction and synthesisData extraction was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis network meta-analysis guidelines. Quality was assessed with the Cochrane Risk of Bias tool. Effect sizes, calculated as standardized mean differences for primary outcomes and risk ratios for discontinuation rates, were assessed in a random-effects model.Main outcomes and measuresPrimary outcomes were efficacy (ie, migraine frequency, number of migraine days, number of headache days, headache frequency, or headache index), safety (ie, treatment discontinuation owing to adverse events), and acceptability (ie, treatment discontinuation for any reason).ResultsTwenty-three studies (2217 patients) were eligible for inclusion. Prophylactic pharmacologic treatments included antiepileptics, antidepressants, calcium channel blockers, antihypertensive agents, and food supplements. In the short term (<5 months), propranolol (standard mean difference, 0.60; 95% CI, 0.03-1.17) and topiramate (standard mean difference, 0.59; 95% CI, 0.03-1.15) were significantly more effective than placebo. However, the 95% prediction intervals for these medications contained the null effect. No significant long-term effects for migraine prophylaxis relative to placebo were found for any intervention.Conclusions and relevanceProphylactic pharmacologic treatments have little evidence supporting efficacy in pediatric migraine. Future research could (1) identify factors associated with individual responses to pharmacologic prophylaxis, (2) analyze fluctuations of migraine attack frequency over time and determine the most clinically relevant length of probable prophylactic treatment, and (3) identify nonpharmacologic targets for migraine prophylaxis.

Project description:Background:Caesarean section rates have increased worldwide in recent decades. Caesarean section is an essential maternal healthcare service. However, it has both maternal and neonatal adverse outcomes. Therefore this systematic review and meta-analysis aimed to estimate the prevalence, indication, and outcomes of caesarean section in Ethiopia. Methods:Twenty three cross-sectional studies with a total population of 36,705 were included. Online databases (PubMed/Medline, Hinari, Web of Science, and Google Scholar) and online university repository was used. All the included papers were extracted and appraised using the standard extraction sheet format and Joanna Briggs Institute respectively. The pooled prevalence of the caesarean section, indications, and outcomes was calculated using the random-effect model. Result:The overall pooled prevalence of Caesarean section was 29.55% (95% CI: 25.46-33.65). Caesarean section is associated with both maternal and neonatal complications. Cephalopelvic disproportion [18.13%(95%CI: 12.72-23.53] was the most common indication of Caesarean section followed by non-reassuring fetal heart rate pattern [19.57% (95%CI: 16.06-23.08]. The common neonatal complications following Caesarean section included low APGAR score, perinatal asphyxia, neonatal sepsis, meconium aspiration syndrome, early neonatal death, stillbirth, and prematurity whereas febrile morbidity, surgical site infection, maternal mortality, severe anemia, and postpartum hemorrhage were the most common maternal complications following Caesarean section. Conclusion:In this systematic review and meta-analysis, the rate of Cesarean section was high. Cephalopelvic disproportion, low Apgar score, and febrile morbidity were the most common indication of Caesarean section, neonatal outcome and maternal morbidity following Caesarean section respectively. Increasing unjustified Caesarean section deliveries as a way to increase different neonatal and maternal complications, then several interventions needed to target both the education of professionals and the public.

Project description:BACKGROUND:Caesarean sections (CSs) are associated with increased maternal and perinatal morbidity, yet rates continue to increase within most countries. Effective interventions are required to reduce the number of non-medically indicated CSs and improve outcomes for women and infants. This paper reports findings of a systematic review of literature related to maternity service organisational interventions that have a primary intention of improving CS rates. METHOD:A three-phase search strategy was implemented to identify studies utilising organisational interventions to improve CS rates in maternity services. The database search (including Cochrane CENTRAL, CINAHL, MEDLINE, Maternity and Infant Care, EMBASE and SCOPUS) was restricted to peer-reviewed journal articles published from 1 January 1980 to 31 December 2017. Reference lists of relevant reviews and included studies were also searched. Primary outcomes were overall, planned, and unplanned CS rates. Secondary outcomes included a suite of birth outcomes. A series of meta-analyses were performed in RevMan, separated by type of organisational intervention and outcome of interest. Summary risk ratios with 95% confidence intervals were presented as the effect measure. Effect sizes were pooled using a random-effects model. RESULTS:Fifteen articles were included in the systematic review, nine of which were included in at least one meta-analysis. Results indicated that, compared with women allocated to usual care, women allocated to midwife-led models of care implemented across pregnancy, labour and birth, and the postnatal period were, on average, less likely to experience CS (overall) (average RR 0.83, 95% CI 0.73 to 0.96), planned CS (average RR 0.75, 95% CI 0.61 to 0.93), and episiotomy (average RR 0.84, 95% CI 0.74 to 0.95). Narratively, audit and feedback, and a hospital policy of mandatory second opinion for CS, were identified as interventions that have potential to reduce CS rates. CONCLUSION:Maternity service leaders should consider the adoption of midwife-led models of care across the maternity episode within their organisations, particularly for women classified as low-risk. Additional studies are required that utilise either audit and feedback, or a hospital policy of mandatory second opinion for CS, to facilitate the quantification of intervention effects within future reviews.

Project description:As compared with vaginal delivery (VD), caesarean section (CS) birth could be associated with increased risk of obesity in young adult offspring. We aimed to evaluate this association by updating data from a systematic review with meta-analysis of observational studies. From 3774 records identified in PubMed and Embase, we retained six studies and added five studies from the last systematic review, for a total of 11 studies. Crude estimates of the association were retrieved from nine cohort studies (n = 143,869), and maximally adjusted estimates were retrieved from eight cohort studies. Young adults born by CS had higher risk of obesity (body mass index [BMI] ≥ 30 kg/m2 ) than young adults born by VD, corresponding to a crude pooled risk ratio (RR) of 1.30 [95% confidence interval (CI) 1.13 to 1.50] and a maximally adjusted pooled RR of 1.22 [95% CI 1.02 to 1.46]. In a sensitivity analysis pooling, five studies that included maternal prepregnancy BMI, a major potential confounding factor, in the set of controlled covariates, the RR was 1.08 [95% CI 0.92 to 1.27]. We concluded that the association between CS and obesity in young adulthood was mostly explained by confounding from maternal prepregnancy BMI.
