Newborn circumcision outcomes: Are parents satisfied with the results?

Background/purpose

Although physician-reported complications following circumcision are very low, parental satisfaction is not well documented. This study examined parental opinions and compared these with those of the medical professional.

Methods

Physicians independently assessed complications and cosmetic outcome following the circumcision. Six weeks post-circumcision, parental report of complications, cosmetic outcome, and overall satisfaction were assessed.

Results

Newborn infants (n = 710) were prospectively recruited and underwent either a Gomco [n = 552 (78 %)] or Plastibell^® [n = 158 (22 %)] circumcision. Physician assessed complication rates were equivalent (Gomco 4.3 % versus Plastibell 5.1 %; p = 0.67), however, parental assessment found a much lower complication rate for Gomco 5.6 % versus Plastibell 12.0 % (p < 0.001). There was no difference between who performed the procedure nor between the techniques in regards to parental rating of overall satisfaction (excellent/good: Gomco 96.9 % versus Plastibell 95.6 %, p = 0.45). However, perceived post-operative pain as scored by parents was significantly higher in patients undergoing Plastibell procedure (6.4 % too much pain) versus Gomco (2.7 %; p = 0.05). Gomco accounted for 72.7 % of parental cosmetically unsatisfactory cases.

Conclusions

Clinicians and parents differed considerably in terms of opinion of cosmetic outcome and occurrence of post-operative complications. This study emphasizes the need for clinicians to better understand and address parental concerns before and after circumcision.     

Human Brain Organoids as Models for Central Nervous System Viral Infection

Pathogenesis of viral infections of the central nervous system (CNS) is poorly understood, and this is partly due to the limitations of currently used preclinical models. Brain organoid models can overcome some of these limitations, as they are generated from human derived stem cells, differentiated in three dimensions (3D), and can mimic human neurodevelopmental characteristics. Therefore, brain organoids have been increasingly used as brain models in research on various viruses, such as Zika virus, severe acute respiratory syndrome coronavirus 2, human cytomegalovirus, and herpes simplex virus. Brain organoids allow for the study of viral tropism, the effect of infection on organoid function, size, and cytoarchitecture, as well as innate immune response; therefore, they provide valuable insight into the pathogenesis of neurotropic viral infections and testing of antivirals in a physiological model. In this review, we summarize the results of studies on viral CNS infection in brain organoids, and we demonstrate the broad application and benefits of using a human 3D model in virology research. At the same time, we describe the limitations of the studies in brain organoids, such as the heterogeneity in organoid generation protocols and age at infection, which result in differences in results between studies, as well as the lack of microglia and a blood brain barrier.     

Left ventricular assist device implants in patients on extracorporeal membrane oxygenation: do we need cardiopulmonary bypass?

Open in a separate window OBJECTIVESImplanting a durable left ventricular assist device (LVAD) in a patient on extracorporeal life support (ECLS) is challenging. The goal of this study was to compare the results of patients from a European registry who had a durable LVAD implanted with or without transition from ECLS to cardiopulmonary bypass (CPB).METHODSA total of 531 patients on ECLS support who had an LVAD implant between January 2010 and August 2018 were analysed; after 1:1 propensity score matching, we identified and compared 175 patients in each group.RESULTSThe duration of preoperative ECLS was 7 [standard deviation (SD) 6] vs 7 (SD 6) days in patients with or without CPB (P = 0.984). The surgical time was longer in the CPB group [285 (SD 72) vs 209 [SD 75] min; P ≤ 0.001). The postoperative chest tube output was comparable [1513 (SD 1311) vs 1390 (SD 1121) ml; P = 0.3]. However, re-exploration for bleeding was necessary in 41% vs 29% of patients with or without CPB (P = 0.01) and a significantly higher number of packed red blood cells and fresh frozen plasma [8 (SD 8) vs 6 (SD 4) units; P = 0.001 and 6 (SD 7) vs 5 (SD 5) units; P = 0.03] were administered to patients operated on with CPB. A postoperative mechanical right ventricular support device was necessary in 50% vs 41% of patients (P = 0.08). The stroke rate was not significantly different (P 0.99). No difference in survival was observed.CONCLUSIONSOmitting CPB for an LVAD implant in patients on ECLS is safe and results in shorter operating time, less re-exploration for bleeding and fewer blood products. However, no survival benefit is observed.     

Service use data analysis of pre-pregnancy psychiatric and somatic diagnoses in women with hyperemesis gravidarum

INTRODUCTION: The purpose of this study was to redress weaknesses in past studies of a psychogenic etiology for hyperemesis gravidarum (HG) by (1) estimating from a known population what proportion of HG cases also have psychiatric diagnoses, (2) determining if psychiatric disorder preceded HG, and (3) re-considering whether non-pregnancy somatic conditions also precede HG. METHODS: We analyzed insurance data for all 11,016 members who gave birth to singletons in 2000-2004, 208 of whom had HG. RESULTS: Prevalence of HG was 1.8% overall, 3.8% with one psychiatric diagnosis, 5.8% with >1 psychiatric diagnosis. One in 10 HG cases had pre-pregnancy depression, anxiety, or substance abuse diagnoses. One in five HG cases had either a psychiatric or a somatic condition (e.g., chronic pelvic pain, dysmenorrhea) diagnosis prior to pregnancy. Pre-pregnancy psychiatric diagnosis doubled the adjusted odds of HG. Combined psychiatric and somatic diagnoses quadrupled the adjusted odds of HG. DISCUSSION: Vomiting is a non-specific sign that may have multiple etiologies. For 10-20% of HG sufferers, vomiting may be a physical comorbidity of a psychiatric condition occurring in the context of pregnancy. Psychobiological research with HG cases with past or current psychiatric diagnoses is needed to consider plausible mechanisms.     

Hygiene practices in abattoir and slaughter slab,determinants and assessment of abattoir and slaughter slab facilities in Abakaliki,Ebonyi State South-East Nigeria

BackgroundWorkers in slaughterhouses engaging in unhygienic practices create conducive environments for zoonoses and meat contamination. Knowledge of hygiene practices and their determinants provides evidence for the design of targeted interventions.ObjectivesWe investigated knowledge and determinants of hygiene practices among workers in slaughterhouses and assessed slaughterhouse facilities in Abakaliki.MethodsWorkers in the Central Meat Market abattoir and Slaughter slab Abakaliki were interviewed in a cross-sectional quantitative study to ascertain their knowledge and hygiene practices while abattoir facilities were assessed using a checklist. Associations were analysed with Chi-square while predictors were determined using binary logistic model.ResultsWe interviewed 188 workers 75.5% and 85.6% of whom had good knowledge and good hygiene practices respectively. However, hand-washing before and after handling meat (44.1%), cleaning work surfaces with soap and water (45.2%) and sanitary disposal of waste (6.9%) were suboptimal. Knowledge of good hygiene practice was a predictor of good hygiene practice (AOR: 4.6, 95% CI: 2.0–11.3, p=0.001). Well water and borehole were present in both slaughterhouses and cold rooms were available in Central Meat market abattoir.ConclusionsThe level of good knowledge was high and this was a determinant of good hygienic practices. Training on hygiene practices is recommended to prevent meat contamination and zoonoses.     

Laser for vascular anomalies: successful outcomes in children

Vascular anomalies can cause both emotional and physical distress to patients, particularly children. The paediatric laser service at Great Ormond Street Hospital (GOSH) treats a range of dermatological conditions including a variety of vascular anomalies, excess hair growth and disfiguring scars. The laser team at GOSH has 25 years of experience in treating a wide variety of paediatric dermatological conditions using various laser therapies. With over 600 new referrals for laser therapy and over 1000 laser procedures each year the GOSH laser team has vast amounts of experience with both common and rare conditions. Excellent clinical outcomes continue to be delivered, and new treatment therapies are constantly being developed to treat more recalcitrant lesions. The adverse effect rates experienced by the GOSH laser patients have been decreasing over the past two decades, reaching the low rate of 0.8% per treated patients per year. This remarkable achievement has been continuously improved by integrating specific and standardized laser protocols for each patient treated, to ensure efficacious and safe laser treatment delivery. Treating vascular anomalies with laser therapy creates significant positive results among the paediatric population, thus laser therapy at GOSH makes a significant impact upon children’s lives with both rare and common vascular anomalies.     

Exogenous hormone use and cutaneous melanoma risk in women: The European Prospective Investigation into Cancer and Nutrition

Evidence suggests an influence of sex hormones on cutaneous melanoma risk, but epidemiologic findings are conflicting. We examined the associations between use of oral contraceptives (OCs) and menopausal hormone therapy (MHT) and melanoma risk in women participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). EPIC is a prospective cohort study initiated in 1992 in 10 European countries. Information on exogenous hormone use at baseline was derived from country-specific self-administered questionnaires. We used Cox proportional hazards regression models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). Over 1992–2015, 1,696 melanoma cases were identified among 334,483 women, whereof 770 cases among 134,758 postmenopausal women. There was a positive, borderline-significant association between OC use and melanoma risk (HR = 1.12, 95% CI = 1.00–1.26), with no detected heterogeneity across countries (p_homogeneity = 0.42). This risk increased linearly with duration of use (p_trend = 0.01). Among postmenopausal women, ever use of MHT was associated with a nonsignificant increase in melanoma risk overall (HR = 1.14, 95% CI = 0.97–1.43), which was heterogeneous across countries (p_homogeneity = 0.05). Our findings do not support a strong and direct association between exogenous hormone use and melanoma risk. In order to better understand these relations, further research should be performed using prospectively collected data including detailed information on types of hormone, and on sun exposure, which may act as an important confounder or effect modifier on these relations.     

How common is non‐alcoholic fatty liver disease in the Asia–Pacific region and are there local differences?

Risk factors for development of non-alcoholic steatohepatitis include obesity, especially central adiposity, glucose intolerance or type 2 diabetes mellitus (T2DM), and dyslipidemia. Non-alcoholic fatty liver disease (NAFLD) is now considered a manifestation of metabolic syndrome. During the last two decades, NAFLD has become the most common chronic liver disease in North America and Europe, but until recently was thought to be uncommon (perhaps due to the lack of study) in Asia. Fatty liver can be identified on imaging modalities (ultrasonography, computed tomography scans, and magnetic resonance imaging) with high sensitivity, but steatohepatitis and fibrosis cannot be distinguished. Thus, an inherent drawback in studying the epidemiology of NAFLD is the lack of definitive laboratory tests, no uniform definition-with different studies using cut-off values of alcohol consumption from <20 g/week to 210 g/week, and case selections where biopsy was used for definition. In studies outside the region, the prevalence of NAFLD varies from 16% to 42% by imaging, and 15-39% of liver biopsies. The major risk factors for NAFLD, central obesity, T2DM, dyslipidemia, and metabolic syndrome, are now widely prevalent and are increasing geometrically in the Asia-Pacific region. It is therefore not surprising that NAFLD is common in this region. Estimates of current prevalence range from 5% to 30%, depending on the population studied. Central obesity, diabetes, and metabolic syndrome are the major risk factors. To date, however, data on the natural history and impact of NAFLD causing serious significant chronic liver disease are lacking and there is a need for prospective, cooperative studies.
