Project description:Rationale & objectiveThere are several well-known anatomical and physiological changes during pregnancy that could contribute to kidney stone formation, but evidence that they increase the risk of kidney stones during pregnancy is lacking. We determined whether there was an increased risk of a first-time symptomatic kidney stone during and after pregnancy.Study designA population-based matched case-control study.Setting & participants945 female first-time symptomatic kidney stone formers aged 15-45 years and 1,890 age-matched female controls in Olmsted County, MN, from 1984-2012. The index date was the date of onset of a symptomatic kidney stone for both the case and her matched controls.ExposureThe primary exposure was pregnancy with assessment for variation in risk across different time intervals before, during, and after pregnancy. Medical records were manually reviewed to determine the conception and delivery dates for pregnancies.OutcomeMedical record-validated first-time symptomatic kidney stone.Analytical approachConditional and unconditional multivariable logistic regression analysis.ResultsCompared with nonpregnant women, the odds of a symptomatic kidney stone forming in women was similar in the first trimester (OR, 0.92; P=0.8), began to increase during the second trimester (OR, 2.00; P=0.007), further increased during the third trimester (OR, 2.69; P=0.001), peaked at 0 to 3 months after delivery (OR, 3.53; P<0.001), and returned to baseline by 1year after delivery. These associations persisted after adjustment for age and race or for diabetes mellitus, hypertension, and obesity. These results did not significantly differ by age, race, time period, or number of prior pregnancies. Having a prior pregnancy (delivery date>1year ago) was also associated with a first-time symptomatic kidney stone (OR, 1.27; P=0.01).LimitationsObservational study design in a predominantly White population. The exact timing of stone formation cannot be determined.ConclusionsPregnancy increases the risk of a first-time symptomatic kidney stone. This risk peaks close to delivery and then improves by 1 year after delivery, though a modest risk of a kidney stone still exists beyond 1 year after delivery.

Project description:Purpose: Evidence regarding distinguishing characteristics of women with symptomatic leiomyomas during pregnancy who undergo myomectomy during pregnancy and those who respond to conservative treatment is sparse because it mostly derives from case reports and small patient series. As the first of its type, the present study analyzed the characteristics of women with symptomatic leiomyomas treated with myomectomy during pregnancy and those treated conservatively. Methods: We performed a computer search of medical records from 1 January 2001 to 31 March 2011 using the International Classification of Diseases Codes for pregnancy, myomectomy and leiomyomas during pregnancy. Results: 27 patients were admitted during pregnancy directly related to leiomyomas; 17 of the 27 patients received conservative treatment for symptomatic leiomyomas, and 10 patients had surgery during pregnancy: 3 had undergone diagnostic surgical procedures and 7 myomectomy. Perioperative and postoperative morbidity was low in all women in our sample. Conclusion: In our pilot study, myomectomy during pregnancy was safely performed in carefully selected patients, with subserosal or pedunculated leiomyomas that failed to respond to conservative treatment, with low perioperative and postoperative morbidity.

Project description:Dengue virus infection during pregnancy increased the risk for any neurologic congenital anomaly in the infant by roughly 50% and for other congenital malformations of brain 4-fold. Our results show an association between dengue during pregnancy and congenital anomalies of the brain, suggesting that flaviviruses other than Zika virus are associated with such malformations.

Project description:Obesity is a growing worldwide epidemic among women of reproductive age, including pregnant women. The increased prevalence of obesity has been accompanied by an increase in gestational weight gain. Maternal obesity has deleterious consequences for both mother and child.To review the recent guidelines from the National Institute for Health and Clinical Excellence and the Institute of Medicine regarding gestational weight gain and interventions to treat obesity during pregnancy.Guidelines on gestational weight gain from these organizations, as well as reports of gestational weight gain in the published literature, are summarized.Many normal and overweight parturients exceed the recommendations in the guidelines, which may contribute to postpartum obesity.Lifestyle changes, including dieting and increased activity, may help to limit excessive gestational weight gain but the optimal strategy remains unclear.

Project description:ImportanceAlthough family priorities influence specialty selection and resident attrition, few studies describe resident perspectives on pregnancy during surgical training.ObjectiveTo directly assess the resident experience of childbearing during training.Design, setting, and participantsA self-administered 74-question survey was electronically distributed in January 2017 to members of the Association of Women Surgeons, to members of the Association of Program Directors in Surgery listserv, and through targeted social media platforms. Surgeons who had 1 or more pregnancies during an Accreditation Council for Graduate Medical Education-accredited US general surgery residency program and completed training in 2007 or later were included. Important themes were identified using focus groups of surgeons who had undergone pregnancy during training in the past 7 years. Additional topics were identified through MEDLINE searches performed from January 2000 to July 2016 combining the keywords pregnancy, resident, attrition, and parenting in any specialty.Main outcomes and measuresDescriptive data on perceptions of work schedule during pregnancy, maternity leave policies, lactation and childcare support, and career satisfaction after childbirth.ResultsThis study included 347 female surgeons (mean [SD] age, 30.5 [2.7] years) with 452 pregnancies. A total of 297 women (85.6%) worked an unmodified schedule until birth, and 220 (63.6%) were concerned that their work schedule adversely affected their health or the health of their unborn child. Residency program maternity leave policies were reported by 121 participants (34.9%). A total of 251 women (78.4%) received maternity leave of 6 weeks or less, and 250 (72.0%) perceived the duration of leave to be inadequate. The American Board of Surgery leave policy was cited as a major barrier to the desired length of leave by 268 of 326 respondents (82.2%). Breastfeeding was important to 329 (95.6%), but 200 (58.1%) stopped earlier than they wished because of poor access to lactation facilities and challenges leaving the operating room to express milk. Sixty-four women (18.4%) had institutional support for childcare, and 231 (66.8%) reported a desire for greater mentorship on integrating a surgical career with motherhood and pregnancy. A total of 135 (39.0%) strongly considered leaving surgical residency, and 102 (29.5%) would discourage female medical students from a surgical career, specifically because of the difficulties of balancing pregnancy and motherhood with training.Conclusions and relevanceThe challenges of having children during surgical residency may have significant workforce implications. A deeper understanding is critical to prevent attrition and to continue recruiting talented students. This survey characterizes these issues to help design interventions to support childbearing residents.

Project description:Pregnancy involves a significant number of physiological changes. A normal pregnancy is essential to ensure healthy maternal and fetal development. We sought to explore whether the urinary proteome could reflect the pregnancy process. Urine samples were collected from pregnant and control rats on various gestational days. The urinary proteome was profiled by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), and differential proteins were obtained by comparing to the gestational day 1 of the same group at each time point. Many pathways related to embryo implantation and trophoblast differentiation were enriched in the early days in urine. Liver, kidney, and bone development started early to be enriched in the pregnant group, but not in the control group. Interestingly, the developmental processes of the fetal heart such as heart looping and endocardial cushion formation could be seen in urine of pregnant rats. Moreover, the timings were consistent with those of embryological studies. The timing of the surfactant appearance in urine was right before birth. The differential proteins related to pancreas development appeared in urine at the time during reported time of pancreatic cell proliferation and differentiation. These processes were enriched only in the pregnant group and not in the control group. Furthermore, coagulation-associated pathways were found to be increasingly prominent before labor. Our results indicated that the urine proteome of pregnant rats can reflect the process of pregnancy, even fetal embryonic development. Maternal urinary proteome detection was earlier than the developmental time point of tissue sections observed by microscopy.

Project description:BackgroundHigh carbohydrate intake has been linked to insulin resistance, obesity, and abnormal serum lipid profiles-conditions which favor gallstone formation.GoalsThe aim of this study was to evaluate the effect of dietary carbohydrate intake on incident gallbladder disease, defined as biliary sludge and stones, during pregnancy.StudyWe prospectively studied 3070 pregnant women who underwent serial gallbladder ultrasound during pregnancy and at 4 to 6 weeks postpartum. All women had at least 2 study ultrasounds for comparison. A semiquantitative food frequency questionnaire was completed by subjects in the early third trimester. Multivariate logistic regression was performed to assess the risk of incident gallbladder disease across quartiles total and individual carbohydrate and individual carbohydrates (starch, sucrose, galactose, fructose, and lactose) intake.ResultsThe cumulative incidence of gallbladder disease was 10.2% by 4 to 6 weeks postpartum. The risk of incident gallbladder disease during pregnancy was significantly higher among women in the highest quartile of total carbohydrate intake versus those in the lowest quartile (odds ratio 2.09, 95% confidence interval 1.02-4.27). High intake of fructose was associated with increased risk even after additional adjustment for total carbohydrate intake (odds ratio 2.18, 95% confidence interval 1.23-3.86, comparing highest with lowest quartile). No association was found between the intake of starch, sucrose, lactose, or galactose and the risk of incident gallbladder disease.ConclusionsHigh consumption of total carbohydrate and fructose may increase the risk of developing gallbladder disease during pregnancy. Dietary modification during pregnancy might reduce gallstone incidence during this time period.

Project description:BackgroundMultiple surgical interventions exist for the treatment of symptomatic knee osteoarthritis, but the surgeon and patient may often have difficulty deciding which interventions are the best option.MethodsWe conducted a systematic review to identify randomized clinical trials (RCTs) that compared complications, revisions, reoperations, and functional outcomes among TKA (total knee arthroplasty), UKA (unicompartmental knee arthroplasty), HTO (high tibial osteotomy), BCA (bicompartmental knee arthroplasty), BIU (bi-unicompartmental knee arthroplasty), and KJD (knee joint distraction). The PubMed, Embase, and Cochrane databases were reviewed for all studies comparing two or more surgical interventions. Direct-comparison meta-analysis and network meta-analysis (NMA) were performed to combine direct and indirect evidence. The risk of bias was assessed using the revised Cochrane risk of bias tool for RCTs.ResultsThis NMA and systematic review included 21 studies (17 RCTs), with a total of 1749 patients. The overall risk-of-bias assessment of the RCTs revealed that 7 studies had low risk, 5 had some concerns, and 9 had high risk. SUCRA (the surface under the cumulative ranking curve) rankings revealed that KJD had the greatest risk of appearing postoperative complications, revisions, and reoperations, and UKA or TKA had the lowest risk. The majority of comparisons among various treatments showed no difference for functional outcomes.ConclusionEach surgical intervention is noninferior to other treatments in functional outcomes, but UKA and TKA are better options to treat OA according to SUCRA rankings by comparing complications, revisions, and reoperations. KJD is an imperfect option for treating OA. Other treatments should be carefully considered for each patient in accordance with their actual conditions. However, this conclusion is limited by the selection of reviewed publications and individual variation of surgical indications for patients.Trial registrationThis study was registered with Research Registry (reviewregistry1395).

Project description:BACKGROUND:Triclosan is an antimicrobial chemical used in consumer products, and exposure is ubiquitous among pregnant women in the United States. Triclosan may reduce the levels of thyroid hormones that are important for fetal growth and development. OBJECTIVE:We investigated the relationship of prenatal triclosan exposure with birth anthropometry and gestational duration. METHODS:We used data from 378 mother-child pairs participating in the Health Outcomes and Measures of the Environment (HOME) Study, a prospective pregnancy and birth cohort from Cincinnati, OH. We measured triclosan concentrations in maternal urine samples collected at 16 and 26 weeks of pregnancy. We abstracted information on neonatal anthropometry and gestational duration from medical records. We used multivariable linear regression to estimate the covariate-adjusted association between the average of the two urinary triclosan concentrations and gestational age standardized weight z-score, length, head circumference, and gestational age at birth. RESULTS:Median urinary triclosan concentrations were 16ng/mL (range: <2.4 to 1501ng/mL). Each 10-fold increase in triclosan was associated with a predicted 0.15 standard deviation decrease (95% CI: -0.30, 0.00) in birth weight z-score, 0.4-cm decrease (95% CI: -0.8, 0.1) in birth length, 0.3-cm decrease (95% CI: -0.5, 0.0) in head circumference, and 0.3-week decrease (95% CI: -0.6, -0.1) in gestational age. Child sex did not modify the associations between triclosan and birth outcomes. CONCLUSIONS:In this cohort, maternal urinary triclosan concentrations during pregnancy were inversely associated with infants' birth weight, length, head circumference, and gestational age.
