Project description:In a population-based case-control study in California of 228 infants, we investigated 75 genetic variants in 20 genes and risk of gastroschisis with regard to maternal age, race/ethnicity, vitamin use, and smoking exposure. We hypothesized that genes related to vascular compromise may interact with environmental factors to affect the risk of gastroschisis. Haplotypes were constructed for 75 gene variants using the HaploView program. Risk for gastroschisis associated with each gene variant was calculated for both the homozygotes and the heterozygotes, with the homozygous wildtypes as the referent. Risks were estimated as odds ratios (ORs) with 95% confidence intervals (CIs) by logistic regression. We found 11 gene variants with increased risk and four variants with decreased risk of gastroschisis for heterozygous (ORh ) or homozygous variants (ORv ) genotypes. These included NOS3 (rs1036145) ORh = 0.4 (95% CI: 0.2-0.7); NOS3 (rs10277237) ORv = 2.7 (95% CI: 1.3-6.0); ADD1 (rs12503220) ORh = 2.9 (95% CI: 1.6-5.4), GNB3 (rs5443) ORh = 0.2 (95% CI: 0.1-0.5), ORv = 0.4 (95% CI: 0.2-0.9); ICAM1 (rs281428) ORv = 6.9 (95% CI: 2.1-22.9), ICAM1 (rs3093030) ORv = 2.6 (95% CI: 1.2-5.6); ICAM4 (rs281438) ORv = 4.9 (95% CI: 1.4-16.6), ICAM5 (rs281417) ORh = 2.1 (95% CI: 1.1-4.1), ORv = 4.8 (95% CI: 1.7-13.6); ICAM5 (rs281440) ORh = 23.7 (95% CI: 5.5-102.5), ORv = 20.6 (95% CI: 3.4-124.3); ICAM5 (rs2075741) ORv = 2.2 (95% CI: 1.1-4.4); NAT1 ORv = 0.3 (95% CI: 0.1-0.9). There were additional associations between several gene variants and gastroschisis among women aged 20-24 and among mothers with and without vitamin use. NOS3, ADD1, ICAM1, ICAM4, and ICAM5 warrant further investigation in additional populations and with the interaction of additional environmental exposures. © 2016 Wiley Periodicals, Inc.

Project description:ImportanceSutureless gastroschisis repair offers an alternative to the traditional sutured method and has been associated with decreased intubation time. Published study results are inconsistent regarding the advantages of sutureless closure.ObjectiveTo compare the clinical outcomes of sutureless and sutured gastroschisis repair.Design, setting, and participantsA single-center cohort review was performed of all consecutive patients (n = 97) who underwent gastroschisis repair from February 1, 2007, to April 30, 2017, at the University of California, San Francisco. Patients' medical records were evaluated for clinical characteristics and outcomes. Cases with incomplete data during initial hospitalization were excluded.Main outcomes and measuresLength of hospital stay, time to full enteral feeds, total parenteral nutrition duration, days requiring intravenous analgesia, days intubated, wound infection rate, antibiotic treatment duration, rate of umbilical hernias that required an operation, and readmission rate.ResultsIn total, 97 patients (47 [48%] were female and 50 [52%] were male with a mean [SD] age of 2.8 [2.8] days) underwent gastroschisis repair, of which 7 were excluded for incomplete medical record. Of the 90 patients included in the study, 50 (56%) underwent sutured closure and 40 (44%) underwent sutureless closure. No statistical difference was found between the sutured and sutureless groups in length of hospital stay (mean [SD] days, 43.9 [40.4] vs 36.7 [21.2]; P = .71), time to full enteral feeds (mean [SD] days, 31.4 [20.2] vs 27.9 [17.3]; P = .22), total parenteral nutrition duration (mean [SD] days, 33.5 [29.8] vs 27.4 [18.2]; P = .23), wound infection rates (14 [28%] vs 10 [25%]; P = .81), and readmission rates (5 [10%] vs 7 [18%]; P = .36). The sutureless group, compared with the sutured group, had substantially fewer days receiving antibiotics (mean [SD], 7.2 [6.4] vs 12.4 [13.2]; P = .003), fewer days intubated (mean [SD], 2.8 [3.3] vs 6.8 [1.3]; P = .001), fewer days receiving intravenous analgesia (mean [SD], 4.2 [4.0] vs 7.1 [4.5]; P = .003), and fewer patients that required silo reduction (25 [63%] vs 48 [96%]; P < .001). Sutureless closures, compared with the sutured technique, had considerably more umbilical hernias requiring surgical repair (5 [13%] vs 0; P = .02).Conclusions and relevanceSutureless repair of gastroschisis appears to be associated with a statistically significant reduction in mechanical ventilation duration and pain medication requirements but may increase umbilical hernia risk. Multicenter randomized clinical trials are necessary to determine the true advantages of the sutureless approach.

Project description:Introduction:There is a significant disparity in outcomes for neonates with gastroschisis in high-income countries (HICs) compared with low-income and middle-income countries (LMICs). Many LMICs report mortality rates between 75% and 100% compared with <4% in HICs. Aim:To undertake a systematic review identifying postnatal interventions associated with improved outcomes for gastroschisis in LMICs. Methods and analysis:Three search strings will be combined: (1) neonates; (2) gastroschisis and other gastrointestinal congenital anomalies requiring similar surgical care; (3) LMICs. Databases to be searched include MEDLINE, EMBASE, Scopus, Web of Science, ProQuest Dissertations and Thesis Global, and the Cochrane Library. Grey literature will be identified through Open-Grey, ClinicalTrials.gov, WHO International Clinical Trials Registry and ISRCTN registry (Springer Nature). Additional studies will be sought from reference lists of included studies. Study screening, selection, data extraction and assessment of methodological quality will be undertaken by two reviewers independently and team consensus sought on discrepancies. The primary outcome of interest is mortality. Secondary outcomes include complications, requirement for ventilation, parenteral nutrition duration and length of hospital stay. Tertiary outcomes include service delivery and implementation outcomes. The methodology of the studies will be appraised. Descriptive statistics and outcomes will be summarised and discussed. Ethics and dissemination:Ethical approval is not required since no new data are being collected. Dissemination will be via open access publication in a peer-reviewed medical journal and distribution among global health, global surgery and children's surgical collaborations and international conferences. Conclusion:This study will systematically review literature focused on postnatal interventions to improve outcomes from gastroschisis in LMICs. Findings can be used to help inform quality improvement projects in low-resource settings for patients with gastroschisis. In the first instance, results will be used to inform a Wellcome Trust-funded multicentre clinical interventional study aimed at improving outcomes for gastroschisis across sub-Saharan Africa.

Project description:BackgroundGastroschisis is unique because of its substantial risk in pregnancies of adolescent women. Adolescents may have poor diet quality, which places them at higher risk of gastroschisis.ObjectiveWe investigated whether better maternal diet quality, measured by 2 different indices, reduced the risk of gastroschisis.MethodsWe used case-control data from the National Birth Defects Prevention Study to investigate maternal diet quality among 1125 gastroschisis cases and 9483 controls (estimated delivery dates between 1997 and 2009). Cases were ascertained from 10 U.S. birth defect surveillance systems. Control subjects were randomly selected from birth certificates or hospital records. Using a 58-item food-frequency questionnaire, interviewers queried mothers about their average food and cereal intake during the year before conception. Diet quality scores [Diet Quality Index (DQI) and Mediterranean diet score (MDS)] were calculated using specific components. Women were excluded if they consumed <500 or >5000 kcal/d, reported pregestational diabetes, or had >1 missing food item. Quartile-specific adjusted ORs (aORs) were calculated, using as reference the lowest quartile.ResultsOverall, we observed a statistically significant decrease with increasing diet quality for both the DQI and MDS. When stratified by maternal race/ethnicity, this finding was confined to Hispanic women. Among Hispanic women, the risk of gastroschisis decreased significantly with increasing DQI quartiles: quartile 2, aOR = 0.58 (95% CI: 0.40, 0.86); quartile 3, aOR = 0.52 (95% CI: 0.36, 0.79); and quartile 4, aOR = 0.48 (95% CI: 0.32, 0.76). Increasing diet quality, as measured by the MDS, showed reduced risk of gastroschisis among women, mostly Hispanic, who were born outside the United States: quartile 2, aOR = 0.62 (95% CI: 0.33, 1.16); quartile 3, aOR = 0.51 (95% CI: 0.28, 0.94); and quartile 4, aOR = 0.50 (95% CI: 0.28, 0.90).ConclusionsIncreasing diet quality was associated with a reduced risk of gastroschisis only among Hispanic and foreign-born women, but these findings require replication.

Project description:The World Health Organization recommended removing all CD4 requirements for initiation of antiretroviral therapy (ART) in resource-limited settings. We examined the pre-ART period to identify and assess factors associated with outcomes of pre-ART care. Four modes of transition out of pre-ART care were considered. Beta estimates from the competing risks Cox models were used to investigate whether the effects of covariates differed by mode of transition. Median CD4 counts at entry showed no meaningful change over time. Advanced disease progression and presence of opportunistic infections were significant predictors of pre-ART mortality. Men were more likely to die before initiating ART, transfer to another facility, or be lost to follow-up than were women. Removing CD4 thresholds is not likely to substantially reduce program mortality prior to ART initiation unless and until patients enroll earlier in disease progression. Care programs should focus on diagnosis and treatment of opportunistic infections to reduce pre-ART mortality.

Project description:Cochlear implants are the most common and successful sensory neuroprosthetic devices. However, reimplantation can be required for medical reasons, device failure, or technological upgrading. Resolving the problem driving the intervention and offering stable or better audiological results are the main challenges. We aimed to analyze the success rate of this intervention and to identify factors influencing speech perception recovery after reimplantation in the pediatric population. We retrospectively collected the causes and the outcomes of 67 consecutive reimplantations in one cochlear implant center over 30 years. Reimplantation resolved the cause without recurrence for 94% of patients. The etiology of deafness, time since implantation, indication of reimplantation, sex, and age did not influence word discrimination test scores in silence, 3 years after surgery. However, adherence to a speech rehabilitation program was statistically associated with gain in perception scores: +8.9% [-2.2; +31.0%] versus -19.0% [-47.5; -7.6%] if no or suboptimal rehabilitation was followed (p = 0.0037). Cochlear reimplantation in children is efficient and is associated with predictable improvement in speech perception, 3 years after intervention. However, good adherence to speech rehabilitation program is necessary and should be discussed with the patient and parents, especially for the indication of reimplantation for technological upgrading.

Project description:BackgroundPrevious studies showed increases in rates of gastroschisis in Canada in the first decade of the 21st century.ObjectiveWe sought to examine the epidemiologic characteristics of gastroschisis in Canada in recent years.MethodsWe conducted a retrospective population-based cohort study of all livebirths and stillbirths delivered in Canada (excluding Quebec) from 2006 to 2017, with information obtained from the Canadian Institute for Health Information. Gastroschisis rates by maternal age, region of residence, and maternal and infant characteristics were quantified using prevalence rate ratios (RR) and 95% confidence intervals (CI). Log-binomial regression was used to quantify the associations between risk factors and gastroschisis.ResultsThere were 1314 gastroschisis cases among 3 364 116 births. The prevalence rate was 3.7 per 10 000 total births in 2006 and 3.4 per 10 000 total births in 2017, with substantial annual variation in rates. The proportion of mothers aged 20-24 years decreased from 16.5% in 2006 to 11.3% in 2017, while the proportion of mothers aged <20 years halved from 4.8% to 2.3%. The prevalence of gastroschisis at birth remained unchanged among mothers aged <20, 20-24 and 30-49 years but increased among mothers aged 25-29 years. The age-adjusted prevalence rate of gastroschisis increased across the period (for 2016-2017 versus 2006-2007 rate ratio [RR] 1.28, 95% CI 1.05, 1.56), and there was substantial regional variation. Risk factors included problematic use of substances (RR 2.61, 95% CI 2.01, 3.39) and hypothyroidism (RR 2.76, 95% CI 1.56, 4.88). There was a North-to-South difference in gastroschisis prevalence (adjusted RR Far North compared with South 1.54, 95% CI 1.11, 2.15).ConclusionGastroschisis birth prevalence rates in Canada have stabilised in recent years compared with the increase documented previously. The substantial geographic variation and North-to-South difference in gastroschisis prevalence may indicate variation in socio-economic status, lifestyle and nutritional patterns.

Project description:BackgroundTransfusion-associated circulatory overload remains underappreciated in the perioperative environment. The authors aimed to characterize risk factors for perioperative transfusion-associated circulatory overload and better understand its impact on patient-important outcomes.MethodsIn this case-control study, 163 adults undergoing noncardiac surgery who developed perioperative transfusion-associated circulatory overload were matched with 726 transfused controls who did not develop respiratory complications. Univariate and multivariable logistic regression analyses were used to evaluate potential risk factors for transfusion-associated circulatory overload. The need for postoperative mechanical ventilation, lengths of intensive care unit and hospital stay, and mortality were compared.ResultsFor this cohort, the mean age was 71 yr and 56% were men. Multivariable analysis revealed the following independent predictors of transfusion-associated circulatory overload: emergency surgery, chronic kidney disease, left ventricular dysfunction, previous β-adrenergic receptor antagonist use, isolated fresh frozen plasma transfusion (vs. isolated erythrocyte transfusion), mixed product transfusion (vs. isolated erythrocyte transfusion), and increasing intraoperative fluid administration. Patients who developed transfusion-associated circulatory overload were more likely to require postoperative mechanical ventilation (73 vs. 33%; P < 0.001) and experienced prolonged intensive care unit (11.1 vs. 6.5 days; P < 0.001) and hospital lengths of stay (19.9 vs. 9.6 days; P < 0.001). Survival was significantly reduced (P < 0.001) in transfusion recipients who developed transfusion-associated circulatory overload (1-yr survival 72 vs. 84%).ConclusionsPerioperative transfusion-associated circulatory overload was associated with a protracted hospital course and increased mortality. Efforts to minimize the incidence of transfusion-associated circulatory overload should focus on the judicious use of intraoperative blood transfusions and nonsanguineous fluid therapies, particularly in patients with chronic kidney disease, left ventricular dysfunction, chronic β-blocker therapy, and those requiring emergency surgery.

Project description:OBJECTIVES:Transfusion-associated circulatory overload is characterized by hydrostatic pulmonary edema following blood transfusion. Restrictive transfusion practice may affect the occurrence and severity of transfusion-associated circulatory overload in critically ill patients. We sought to examine contemporary risk factors and outcomes for transfusion-associated circulatory overload. DESIGN:Case-control study. SETTING:Four tertiary care hospitals. PATIENTS:We prospectively enrolled 200 patients with transfusion-associated circulatory overload identified by active surveillance and 405 controls matched by transfusion intensity. INTERVENTIONS:None. MEASUREMENTS AND MAIN RESULTS:Among 20,845 transfused patients who received 128,263 blood components from May 2015 until July 2016, transfusion-associated circulatory overload incidence was one case per 100 transfused patients. In addition to cardiovascular comorbidities, multivariable analysis identified the following independent predictors of transfusion-associated circulatory overload: acute kidney injury, emergency surgery, pretransfusion diuretic use, and plasma transfusion-the latter especially in females. Compared with matched controls, transfusion-associated circulatory overload cases were more likely to require mechanical ventilation (71% vs 49%; p < 0.001), experienced longer intensive care and hospital lengths of stay following transfusion, and had higher mortality (21% vs 11%; p = 0.02) even after adjustment for other potentially confounding variables. CONCLUSIONS:Despite restrictive transfusion practice, transfusion-associated circulatory overload remains a frequent complication of transfusion and is an independent risk factor for in-hospital morbidity and mortality. In addition to cardiovascular and renal risk factors, plasma transfusion was associated with transfusion-associated circulatory overload after controlling for other covariates. Additional research is needed to examine the benefit of reduced erythrocyte or plasma exposure in patients at high risk for transfusion-associated circulatory overload.
