The Influence of Oral Dydrogesterone and Vaginal Progesterone on Threatened Abortion: A Systematic Review and Meta-Analysis

Objective. To conduct systematic analyses to evaluate the efficacy of progesterone therapy for the prevention of miscarriages in pregnant women experiencing threatened abortion. Methods. In November 2016, we performed a systematic literature search and identified 51 articles in PubMed, Embase, and Cochrane databases. We identified nine randomized trials that included 913 pregnant women (including 322 treated with oral dydrogesterone, 213 treated with vaginal progesterone, and 378 control subjects) who met the selection criteria. Results. The incidence of miscarriage was significantly lower in the total progesterone group than in the control group (13.0% versus 21.7%; odds ratio, 0.53; 95% confidence interval (CI), 0.36 to 0.78; P=0.001; I2, 0%). Moreover, the incidence of miscarriage was significantly lower in the oral dydrogesterone group than in the control group (11.7% versus 22.6%; odds ratio, 0.43; 95% CI, 0.26 to 0.71; P=0.001; I2, 0%) and was lower in the vaginal progesterone group than in the control group, although this difference was nonsignificant (15.4% versus 20.3%; odds ratio, 0.72; 95% CI, 0.39 to 1.34; P=0.30; I2, 0%). However, the incidence of miscarriage was not different between the oral dydrogesterone and vaginal progesterone groups. Conclusion. Progesterone therapy, especially oral dydrogesterone, can effectively prevent miscarriage in pregnant women experiencing threatened abortion.

Purpose Fluourouracil (FU) is a mainstay of chemotherapy, although toxicities are common. Genetic biomarkers have been used to predict these adverse events, but their utility is uncertain. Patients and Methods We tested candidate polymorphisms identified from a systematic literature search for associations with capecitabine toxicity in 927 patients with colorectal cancer in the Quick and Simple and Reliable trial (QUASAR2). We then performed meta-analysis of QUASAR2 and 16 published studies (n = 4,855 patients) to examine the polymorphisms in various FU monotherapy and combination therapy regimens. Results Global capecitabine toxicity (grades 0/1/2 v grades 3/4/5) was associated with the rare, functional DPYD alleles 2846T>A and *2A (combined odds ratio, 5.51; P = .0013) and with the common TYMS polymorphisms 5′VNTR2R/3R and 3′UTR 6bp ins-del (combined odds ratio, 1.31; P = 9.4 × 10−6). There was weaker evidence that these polymorphisms predict toxicity from bolus and infusional FU monotherapy. No good evidence of association with toxicity was found for the remaining polymorphisms, including several currently included in predictive kits. No polymorphisms were associated with toxicity in combination regimens. Conclusion A panel of genetic biomarkers for capecitabine monotherapy toxicity would currently comprise only the four DPYD and TYMS variants above. We estimate this test could provide 26% sensitivity, 86% specificity, and 49% positive predictive value—better than most available commercial kits, but suboptimal for clinical use. The test panel might be extended to include additional, rare DPYD variants functionally equivalent to *2A and 2846A, though insufficient evidence supports its use in bolus, infusional, or combination FU. There remains a need to identify further markers of FU toxicity for all regimens.

Objective.Several recent reviews of published studies have shown that the eradication ofH. pyloriinfection in patients with ITP improved thrombocytopenia in about half of the cases. However, most included studies were observational case series. We performed the first meta-analysis of randomized trials to gain a better insight into the effect ofH. pylorieradication in ITP patients.Methods.A systematic computerized search of the electronic databases including PubMed, EMBASE, Google Scholar, and Cochrane Library (up to December 2017) was conducted.Results.From six studies, a total of 241 patients (125 in eradication group and 116 in control group) were included in the meta-analysis. Patients in the eradication group showed significantly higher overall platelet response rate than those in the control group (odds ratio = 1.93, 95% confidence interval: 1.01–3.71,P=0.05). In the subgroup analysis, however, children in the eradication group failed to show statistically better response rate than those in the noneradication group (odds ratio = 1.80, 95% confidence interval: 0.88–3.65,P=0.11).Conclusions.This meta-analysis indicates thatH. pylorieradication has a significant therapeutic effect in patients with ITP. Considering the intrinsic limits in the design and sample size of the included studies, however, large randomized controlled trials are warranted to validate the therapeutic impact ofH. pylorieradication in adults as well as children with ITP.

Abstract Background The impact of maternal obesity extends beyond birth, being independently associated with an increased risk of child obesity. Current evidence demonstrates that women provided with a dietary intervention during pregnancy improve their dietary quality and have a modest reduction in gestational weight gain. However, the effect of this on longer-term childhood obesity-related outcomes is unknown. Methods We conducted an individual participant data meta-analysis from RCTs in which women with a singleton, live gestation between 10+0 and 20+0 weeks and body mass index (BMI) ≥ 25 kg/m2 in early pregnancy were randomised to a diet and/or lifestyle intervention or continued standard antenatal care and in which longer-term maternal and child follow-up at 3–5 years of age had been undertaken. The primary childhood outcome was BMI z-score above the 90th percentile. Secondary childhood outcomes included skinfold thickness measurements and body circumferences, fat-free mass, dietary and physical activity patterns, blood pressure, and neurodevelopment. Results Seven primary trials where follow-up of participants occurred were identified by a systematic literature search within the International Weight Management in Pregnancy (i-WIP) Collaborative Group collaboration, with six providing individual participant data. No additional studies were identified after a systematic literature search. A total of 2529 children and 2383 women contributed data. Approximately 30% of all child participants had a BMI z-score above the 90th percentile, with no significant difference between the intervention and control groups (aRR 0.97; 95% CI 0.87, 1.08; p=0.610). There were no statistically significant differences identified for any of the secondary outcome measures. Conclusions In overweight and obese pregnant women, we found no evidence that maternal dietary and/or lifestyle intervention during pregnancy modifies the risk of early childhood obesity. Future research may need to target the pre-conception period in women and early childhood interventions. Trial registration PROSPERO, CRD42016047165

Early Childhood Research

Engagement in early childhood has been linked with later achievement, but the relation between these variables and how they are measured in early childhood requires examination. We estimated the overall association between academic engagement and achievement in children prior to kindergarten entry. Our systematic literature search yielded 13,521 reports for structured eligibility screening; from this pool of studies, we identified 21 unique data sets, with 199 effect sizes for analysis. We coded eligible studies, extracted effect sizes, accounted for effect size dependency, and used random-effects models to synthesize findings. The overall correlation between academic engagement and achievement was r = .24 (range: −.08 to −.71), and moderator analyses did not significantly predict the relation between the two constructs. This study aligns with previous research on this topic and examines issues related to these measures, their constraints, and applications as they pertain to early childhood research.

Objective To evaluate the efficacy and safety of spinal anaesthesia using dexmedetomidine for caesarean section. Methods PubMed, The Cochrane Library, and CNKI were searched for relevant literature. Results The incidence of nausea and vomiting in the dexmedetomidine group was significantly lower than that in the control group (OR = 0.21, 95% CI: 0.12–0.35, P < 0.00001). No difference was found in the incidence of pruritus between the two groups (OR = 1.21, 95% CI: 0.36–4.09, P = 0.76).The dexmedetomidine group had a higher incidence of bradycardia than did the control group (OR = 2.20, 95% CI: 1.02–4.77, P = 0.05). The incidence of shivering in the dexmedetomidine group was significantly lower than that in the control group (OR = 0.20, 95% CI: 0.13–0.32, P < 0.00001). The incidence of hypotension was not different between the two groups (OR = 0.88, 95% CI: 0.49–1.56, P = 0.65). Conclusion Dexmedetomidine can decrease the incidence of nausea, vomiting, bradycardia, and shivering with spinal anaesthesia during caesarean section.

Ischemic Events

Background: Data regarding intraprocedural thrombotic events (IPTE) including slow reflow or no reflow, distal embolization, intraprocedural stent thrombosis and abrupt vessel closure during PCI for acute coronary syndrome (ACS) are scarce. Their association with subsequent adverse ischemic events needs further investigation. Aim: To evaluate effect of IPTE on in-hospital and at 30-days clinical outcomes after PCI for ACS. Hypothesis: IPTE during PCI are associated with adverse ischemic events while in-hospital and at 30 days. Methods: We performed a literature search of all published full-length articles of randomized trials that reported data on patients with IPTE compared with no IPTE during PCI for patients with ACS. We calculated odd ratios via random effects model for in-hospital ischemic outcomes and 30 day outcomes. Results: Our literature search yielded 3 randomized trials reporting clinical outcomes with IPTE and no IPTE for ACS patients undergoing PCI: ACUITY, HORIZONS-AMI and EARLY-ACS trials. We report clinical outcomes (in-hospital and at 30 days) in 8,043 patients in total, of those 673 had IPTE. At 30 days, patients with IPTE had more major adverse cardiovascular events (MACE) (Odds ratio (OR) 3.97, 95% Confidence interval (CI) [1.81-8.69]; p=0.0006), mortality (OR 4.54, 95% CI [1.99, 10.39]; p=0.0003), myocardial infarction (OR 4.54, 95% CI [1.99, 10.39]; p=0.0003), repeat revascularization (OR 4.54, 95% CI [1.99, 10.39]; p=0.0003), total stent thrombosis (OR 4.54, 95% CI [1.99, 10.39]; p=0.0003) and non-CABG related major bleeding (OR 4.54, 95% CI [1.99, 10.39]; p=0.0003) than those with no IPTE. Similarly, in-hospital clinical outcomes were all significantly higher in patients with IPTE than those without. Conclusion: IPTE during PCI is associated with more adverse ischemic events, including mortality, both in-hospital and at 30 days.

PURPOSE: Recent randomized trials in women with node-positive breast cancer who received systemic treatment report that locoregional radiation therapy improves survival. Previous trials failed to detect a difference in survival that results from its use. A systematic review of randomized trials that examine the effectiveness of locoregional radiation therapy in patients treated by definitive surgery and adjuvant systemic therapy was conducted. METHODS: Randomized trials published between 1967 and 1999 were identified through MEDLINE database, CancerLit database, and reference lists of relevant articles. Relevant data was abstracted. The results of randomized trials were pooled using meta-analyses to estimate the effect of treatment on any recurrence, locoregional recurrence, and mortality. RESULTS: Eighteen trials that involved a total of 6,367 patients were identified. Most trials included both pre- and postmenopausal women with node-positive breast cancer treated with modified radical mastectomy. The type of systemic therapy received, sites irradiated, techniques used, and doses of radiation delivered varied between trials. Data on toxicity were infrequently reported. Radiation was shown to reduce the risk of any recurrence (odds ratio, 0.69; 95% confidence interval [CI], 0.58 to 0.83), local recurrence (odds ratio, 0.25; 95% CI, 0.19 to 0.34), and mortality (odds ratio, 0.83; 95% CI, 0.74 to 0.94). CONCLUSION: Locoregional radiation after surgery in patients treated with systemic therapy reduced mortality. Several questions remain on how these results should be translated into current-day clinical practice.

Enamel Formation

Previous studies have reported the association between multiple genetic variants in enamel formation-related genes and the risk of dental caries with inconsistent results. We performed a systematic literature search of the PubMed, Cochrane Library, HuGE and Google Scholar databases for studies published before March 21, 2020 and conducted meta-, gene-based and gene-cluster analysis on the association between genetic variants in enamel- formation-related genes and the risk of dental caries. Our systematic literature search identified 21 relevant publications including a total of 24 studies for analysis. The genetic variant rs17878486 in AMELX was significantly associated with dental caries risk (OR=1.40, 95% CI: 1.02-1.93, P=0.037). We found no significant association between the risk of dental caries with rs12640848 in ENAM (OR=1.15, 95% CI: 0.88-1.52, P=0.310), rs1784418 in MMP20 (OR=1.07, 95% CI: 0.76-1.49, P=0.702) and rs3796704 in ENAM (OR=1.06, 95% CI: 0.96-1.17, P=0.228). Gene-based analysis indicated that multiple genetic variants in AMELX showed joint association with the risk of dental caries (6 variants; P<10-5), so did genetic variants in MMP13 (3 variants; P=0.004), MMP2 (3 variants; P<10-5), MMP20 (2 variants; P<10-5) and MMP3 (2 variants; P<10-5). The gene-cluster analysis indicated a significant association between the genetic variants in this enamel-formation gene cluster and the risk of dental caries (P<10-5). The present meta-analysis revealed that genetic variant rs17878486 in AMELX were associated with dental caries, and multiple genetic variants in enamel-formation-related genes jointly contribute to the risk of dental caries, supporting the role of genetic variants in the enamel-formation genes in the etiology of dental caries.

Background: Our aim was to conduct a review to summarize the existing information regarding the effects of shoe collar height in altering ankle sprain mechanics in athletes. Methods: A systematic literature search of PubMed, Embase, MEDLINE, and SPORTDiscus was conducted in September 2019. Results: There were 10 studies published from 1993 to 2019 that were included. Most studies showed high-top shoes limited ankle sprain kinematics and increased resistance to inversion moment in static but not dynamic testing. High-top shoes were associated with delayed pre-landing ankle evertor muscle activation and smaller electromyography amplitudes. Conclusions: There is currently weak evidence to support that high-top shoes can limit ankle sprain kinematics in dynamic testing. Further studies with more consistent study interventions and outcome variables are needed to definitively establish the effects of shoe collar height on ankle sprain mechanics in athletes. The Translational Potential of this Article: Multiple studies on the effects of shoe collar height and ankle sprain mechanics have been performed but there is a lack of consistency in terms of study design, intervention, and outcome measures. A formal systematic review and meta-analysis were not applicable due to the heterogeneity of studies, and mixed results from these studies can be confusing to interpret, making further research on this topic difficult as a result of lack of future direction. We summarized the existing literature on this topic to provide a clearer picture and guide future research on this controversial matter.
