Use of everolimus following kidney transplantation during pregnancy: A case report and systematic review.

OBJECTIVE: There is limited safety data on the use of everolimus during pregnancy. In this study, we present the maternal and neonatal outcomes of everolimus used throughout the course of pregnancy and conducted a systematic review of reports of everolimus use after organ transplantation during pregnancy. CASE REPORT: A woman with type 1 diabetes who underwent kidney transplantation was treated with tacrolimus, everolimus, and prednisolone. Two years later, she became pregnant. At 27 weeks of gestation, an emergent cesarean delivery was performed owing to severe preeclampsia and fetal distress. No congenital malformation was noted in the baby at a corrected age of 4 months, and the maternal renal function remained stable. CONCLUSION: Our systematic review did not identify evidence of teratogenicity in babies exposed to everolimus as an immunosuppressant after transplantation. To better assess the risk of exposure to everolimus during pregnancy, all cases of new pregnancies occurring in transplant recipients receiving treatment with mammalian target of rapamycin inhibitor inhibitors should be reported.

Correction of Breech Presentation with Moxibustion and Acupuncture: A Systematic Review and Meta-Analysis.

Acupuncture-type interventions (such as moxibustion and acupuncture) at Bladder 67 (BL67, Zhiyin point) have been proposed to have positive effects on breech presentation. The aim of this systematic review and meta-analysis was to evaluate the effectiveness and safety of moxibustion and acupuncture in correcting breech presentation. We searched PubMed, MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), the Chinese Electronic Periodical Services (CEPS), and databases at ClinicalTrials.gov to identify relevant randomized controlled trials (RCTs). In this study, sixteen RCTs involving 2555 participants were included. Compared to control, moxibustion significantly increased cephalic presentation at birth (RR = 1.39; 95% CI = 1.21-1.58). Moxibustion also seemed to elicit better clinical outcomes in the Asian population (RR = 1.42; 95% CI = 1.21-1.67) than in the non-Asian population (RR = 1.20; 95% CI = 1.01-1.43). The effects of acupuncture on correcting breech presentation after sensitivity analysis were inconsistent relative to control. The effect of moxibustion plus acupuncture was synergistic for correcting breech presentation (RR = 1.53; 95% CI = 1.26-1.86) in one RCT. Our findings suggest that moxibustion therapy has positive effects on correcting breech presentation, especially in the Asian population.

Changes in Intraocular Pressure During Hemodialysis: A Meta-analysis.

PRCIS: Acetate dialysate causes elevation of intradialytic intraocular pressure (IOP) and contributed to the rise of IOP in the early years of hemodialysis (HD). Glaucoma, narrow-angle, or impaired aqueous outflow is another moderator causing a rise of intradialytic IOP. PURPOSE: Severe IOP elevation during HD has been described in many case reports. However, the results of primary studies are conflicting. This meta-analysis examined the impact of HD on IOP and explored the potential moderators. METHODS: Medline, PubMed, Embase, Web of Science, and Cochrane were systematically searched. Before-after studies reporting the change of IOP during HD were included. Intradialytic IOP changes were calculated based on 4 different definitions: highest-baseline, lowest-baseline, max-baseline, and end-baseline IOP difference. Standardized mean difference (SMD) was pooled using the random-effects model. RESULTS: Fifty-three studies involving 1903 participants and 2845 eyes were included. Overall data pooling showed no significant rise in intradialytic IOP. However, subgroup analysis showed an intradialytic IOP rise before 1986 (SMD: 0.593; 95% confidence interval: 0.169-1.018; max-baseline IOP difference as representative; most studies using acetate dialysate), no change between 1986 and 2005 (using both acetate and bicarbonate), and a decline after 2005 (SMD: -0.222; 95% confidence interval: -0.382 to -0.063; entirely using bicarbonate). Multivariable meta-regression showed only the type of dialysate, but not publication year or other potential factors, as a significant moderator. Glaucoma was found to be another significant moderator independent of the dialysate effect in bivariate meta-regression. CONCLUSIONS: IOP elevation in the early years of HD with the use of acetate dialysate is less of a clinical problem following its substitution with bicarbonate dialysate. However, physicians should still be cautious of potential IOP changes in the HD population with glaucoma.

Effect of drug interactions between carbapenems and valproate on serum valproate concentration: a systematic review and meta-analysis.

Background: Concurrent use of valproate and carbapenem antibiotics may decrease serum valproate concentration (SVC). This study evaluated the effects of carbapenem-valproate drug interactions. Research design and methods: We screened PubMed, EMBASE, and Cochrane databases for eligible prospective or retrospective studies that evaluated the effect of concurrent use of carbapenem and valproate compared with valproate alone on SVC. Primary outcomes were the change in SVC from before the addition of the carbapenem to the SVC during the use of carbapenems and after carbapenem discontinuation, and seizure-related outcomes. Secondary outcomes were the influence of valproate or carbapenem dose on SVC and Drug Interaction Probability Scale scores. Results: Twelve studies (633 patients) were included. Compared with valproate alone, combination treatment with carbapenem substantially decreased mean SVC (mean difference, -43.98 mg/L; 95% confidence interval, -48.18 to -39.78). The onset of SVC decreases was within 1-3 days following carbapenem initiation. Seizure frequency increased by 26.3% during combination treatment. No difference was found in mean SVC between the different doses of valproate or carbapenem during combination treatment. Mean SVC increased to similar pre-carbapenem level within 1 to 2 weeks after carbapenem discontinuation. Conclusions: The drug interaction between valproate and carbapenem causes substantial SVC decreases, even to subtherapeutic levels, which may increase the risk of seizures.

Academic outcomes of flipped classroom learning: a meta-analysis.

CONTEXT: The flipped classroom (FC), reversing lecture and homework elements of a course, is popular in medical education. The FC uses technology-enhanced pre-class learning to transmit knowledge, incorporating in-class interaction to enhance higher cognitive learning. However, the FC model is expensive and research on its effectiveness remains inconclusive. The aim of this study was to compare the efficacy of the FC model over traditional lecture-based (LB) learning by meta-analysis. METHODS: We systematically searched MEDLINE, PubMed, ERIC, CINAHL, EMBASE, reference lists and Association for Medical Education in Europe (AMEE) conference books. Controlled trials comparing academic outcomes between the FC and LB approaches in higher education were considered eligible. The main findings were pooled using a random-effects model when appropriate. RESULTS: Forty-six studies (9026 participants) were included, comprising four randomised controlled trials (RCTs), 19 quasi-experimental studies and 23 cohort studies. Study populations were health science (n = 32) and non health science (n = 14) students. The risk of bias was high (36/37 articles). Meta-analyses revealed that the FC had significantly better outcomes than the LB method in examination scores (post-intervention and pre-post change) and course grades, but not in objective structured clinical examination scores. Subgroup analyses showed the advantage of the FC was not observed in RCTs, non-USA countries, nursing and other health science disciplines and earlier publication years (2013 and 2014). Cumulative analysis and meta-regression suggested a tendency for progressively better outcomes by year. Outcome assessments rarely focused on behaviour change. CONCLUSIONS: The FC method is associated with greater academic achievement than the LB approach for higher-level learning outcomes, which has become more obvious in recent years. However, results should be interpreted with caution because of the high methodological diversity, statistical heterogeneity and risk of bias in the studies used. Future studies should have high methodological rigour, a standardised FC format and utilise assessment tools evaluating higher cognitive learning and behaviour change to further examine differences between FC and LB learning.
