Background: This study aimed to determine the revision outcome between a centrally fixed stemless anatomic design and other total anatomic shoulder replacements using data from a large national arthroplasty registry., Methods: The study period was from December 2011 to December 2022 and included three cohorts; primary Affinis stemless anatomic (AFS), all other primary total stemless anatomic (sTSA) and primary total stemmed anatomic shoulder arthroplasty (aTSA). The endpoint was all-cause revision using cumulative percent revision (CPR). Hazard ratio (HR) models were adjusted for age and gender., Results: There were 2489 primary AFS, 1593 primary sTSA and 11,023 primary aTSA. There was no difference in revision rates between the AFS and the sTSA group. The aTSA group had a significantly higher rate of revision compared to both AFS (HR = 1.63, 95% confidence interval (CI) 1.30-2.05, p  < 0.001) and sTSA (HR = 1.61, 95% CI 1.21-2.15, p  = 0.001). However, sub-analyses stratifying for highly crosslinked polyethylene (XLPE) showed no differences between the groups., Discussion: The rates of revision between the AFS design and other stemless prostheses were similar. Stemless had lower revision rates to aTSA. When only considering XLPE cemented glenoids, there was no significant difference in revision rates., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Background: Health workers' (HWs') perspectives on the quality of maternal and newborn care (QMNC) are not routinely collected. In this cross-sectional study, we aimed to document HWs' perspectives on QMNC around childbirth in 12 World Health Organization (WHO) European countries., Methods: HWs involved in maternal/neonatal care for at least one year between March 2020 and March 2023 answered an online validated WHO standards-based questionnaire collecting 40 quality measures for improving QMNC. A QMNC index (score 0-400) was calculated as a synthetic measure., Results: Data from 4143 respondents were analysed. For 39 out of 40 quality measures, at least 20% of HWs reported a 'need for improvement', with large variations across countries. Effective training on healthy women/newborns management (n = 2748, 66.3%), availability of informed consent job aids (n = 2770, 66.9%), and effective training on women/newborns rights (n = 2714, 65.5%) presented the highest proportion of HWs stating 'need for improvement'. Overall, 64.8% (n = 2684) of respondents declared that HWs' numbers were insufficient for appropriate care (66.3% in Portugal and 86.6% in Poland), and 22.4% described staff censorship (16.3% in Germany and 56.7% in Poland). The reported QMNC index was low in all countries (Poland median (MD) = 210.60, interquartile range (IQR) = 155.71, 273.57; Norway MD = 277.86; IQR = 244.32, 308.30). The 'experience of care' domain presented in eight countries had significantly lower scores than the other domains (P < 0.001). Over time, there was a significant monthly linear decrease in the QMNC index (P < 0.001), lacking correlation with the coronavirus disease 2019 (COVID-19) pandemic trends (P > 0.05). Multivariate analyses confirmed large QMNC variation by country. HWs with <10 years of experience, HWs from public facilities, and midwives rated QMNC with significantly lower scores (P < 0.001)., Conclusions: HWs from 12 European countries reported significant gaps in QMNC, lacking association with COVID-19 pandemic trends. Routine monitoring of QMNC and tailored actions are needed to improve health services for the benefit of both users and providers., Registration: ClinicalTrials.gov NCT04847336., Competing Interests: Disclosure of interests: The authors completed the ICMJE Disclosure of Interest Form (available upon request from the corresponding author) and disclose no relevant interests., (Copyright © 2024 by the Journal of Global Health.

The human brain grows rapidly in early life which requires adequate nutrition. Human milk provides optimal nutrition for the developing brain, and breastfeeding significantly improves the cognition development of infants. These benefits have been largely attributed to human milk oligosaccharides (HMOS), associated with sialic acid (Sia). Subsequently, sialylated HMOS present a vital source of exogenous Sia to infants. Sialic acid is a key molecule essential for proper development of gangliosides, and therefore critical in brain development and function. Recent pre-clinical studies suggest dietary supplementation with Sia or sialylated oligosaccharides enhances intelligence and cognition performance in early and later life. Furthermore, emerging evidence suggests the involvement of Sia in brain homeostasis and disbalance correlates with common pathologies such as Alzheimer's disease (AD). Therefore, this review will discuss early brain health and development and the role of Sia in this process. Additionally, studies associating breastfeeding and specific HMOS to benefits in cognitive development are critically assessed. Furthermore, the review will assess studies implying the potential role of HMOS and microbiota in brain development via the gut-brain axis. Finally, the review will summarize recent advances regarding the role of Sia in neurodegenerative disease in later life and potential roles of dietary Sia sources.

Introduction: Poor genital self-image is a common phenomenon leading to an increasing interest in female genital surgery over the last years., Aim: The aim was to correlate objective measurements of the labia minora with the individual subjective perception of the labial size., Methods: In a cross-sectional study with 200 premenopausal women (median age 33.5 years) presenting for gynecological issues other than vulvar diseases, labial width and length were measured, and psychological and physical complaints were assessed. Multivariable logistic regression analyses were performed to identify factors that influenced self-reported complaints and subjective perception of labia size., Main Outcome Measure: The main outcome measure was labial appearance (width and length in mm, color), subjective perception of the labial size, and complaints., Results: The median width of the labia minora was 19.0 mm (interquartile range = 12.6-27.5), and the median length was 35.5 mm (interquartile range = 27.8-48.9). The objective size of the labia was significantly associated with womens' subjective perception of the labial size, but not with self-reported complaints. Nearly one-third of the women (n = 53, 27%) reported complaints of their labia minora which were mainly physical (n = 41, 77%) or a combination of physical and psychological problems (n = 9, 17%), while only a small group reported experiencing only psychological complaints (n = 3, 6%). Predictors of complaints were previous cosmetic surgery and the subjective perception of the labia size. The latter was significantly associated with discomfort during intercourse and when visiting a sauna and by labia minora that protruded over the labia majora., Clinical Implications: Cutoff values to define labial hypertrophy and to justify labial reduction surgery should be avoided., Strength & Limitations: This is a large sample of labial measurements in women not seeking labiaplasty. Standardized and validated questions regarding quality of life, sexuality, and body image could have provided more insight into psychological aspects., Conclusion: These data demonstrate the variability of labial anatomy and its perception.

More than 40years ago, the endogenous opioids were first described. Their role as important neuromodulators of pain and their influence on a variety of neuroendocrine control systems within the central nervous system has been recognized. More recently, endogenous opioids and their receptor have been identified in a variety of reproductive and non-reproductive tissues outside the central nervous system. What role the opioid system plays in these peripheral tissues and organs is not completely understood and thus the subjects of current research. In the central nervous system, endogenous opioids inhibit pulsatile Gonadotropin Releasing Hormone (GnRH) release, affecting the release of gonadotropins from the pituitary, and thus mediating stress response within the central nervous-pituitary-gonadal axes in both women and men-Peripherally, endogenous opioids have been demonstrated to be present-among other organs-in the pancreas and in the ovary, where they are produced by granulosa cells and may influence oocyte maturation. In men, endogenous opioids play a role in sperm production within the testis. Opioid antagonists such as naltrexone have been used to restore cyclicity in women through improvement in insulin resistance, GnRH-pulsatility and hyperandrogenemia stemming from specific pathophysiological conditions such as hypothalamic amenorrhea, polycystic ovarian syndrome, hyperinsulinemia, ovarian hyperstimulation syndrome. Opioid antagonists have also been used to treat male sexual disorders and male infertility. In summary, endogenous opioids exert a variety of actions within the reproductive system which are reviewed in this chapter., (© 2019 Elsevier Inc. All rights reserved.)

Background: Connatal urinary ascites is rare in females without associated malformations and occurs following bladder rupture., Case Presentation: A female very preterm was delivered by caesarean section because of abnormal Doppler findings. The mother suffered from viral pneumonia requiring intensive care in the third trimester of pregnancy. Serial fetal ultrasound examinations showed a megacystis and ascites. Postnatally, pronounced isolated ascites was drained and its urinary nature was confirmed. The bladder leak was demonstrated when blue dye, instilled via a Foley catheter, appeared in the ascitic drain. After removal of the catheter spontaneous micturition was unremarkable. A micturating cystourethrogram showed spontaneous closure of the bladder leak., Conclusion: The female infant experienced fetal bladder rupture and connatal urinary ascites due to maternal pneumonia and intensive care. The use of blue dye is an effective alternative method to any contrast media radiography and should be considered, especially in very preterm infants.

Purpose: The optimal number of fixation pins for minimally invasive cutting guides in computer-navigated arthroplasty has not been determined. The authors hypothesized that more fixation pins will lead to greater mechanical stability and more accurate resections., Materials and Method: 12 bovine knee joints were divided into three groups with differing numbers of fixation pins. The ASM [Stryker] knee navigation system was utilized to perform resections, and accuracy of alignment and posterior slope was measured. Comparison was performed between the groups to calculate average differences between predicted and actual resection with differing number of pins., Results: The difference between actual and predicted values showed a trend toward diminishing with a greater number of fixation pins. The mean difference in coronal alignment of predicted versus actual resection was 0.75° for two fixation pins, 0.5° for three pins and 1° for four fixation pins. Similarly, the difference between posterior slope was 2.75°, 2°, and 1°, respectively., Conclusion: This study reveals a trend toward greater accuracy of resections with more fixation pins. Further investigation may be beneficial.

Purpose: To evaluate the efficacy of a combined protocol of mifepristone and misoprostol in the management of early pregnancy failure (EPF) and the average time to expulsion of tissue and rate of side effects., Methods: Retrospective chart review of all consecutive women treated with primary medical management for EPF at our institution from 2006 to 2012., Results: 168 patients were included in the present study. The overall success rate, defined as the absence of the need for surgical intervention, was 61 % and did not differ by calendar year. There was no difference in success rate grouped by diagnosis [intrauterine embryonic/fetal demise (IUED/IUFD) vs. anembryonic gestation; p = 0.30] or gestational age (<9 or ≥9 weeks; p = 0.48). The success rate varied significantly according to the required dose of misoprostol, ≤800 or >800 μg (68 vs. 50 %, p = 0.029). Of the possible predictive factors of success, only the dose of misoprostol required was a significant independent negative predictor. Mean and median time to tissue expulsion after the first dose of misoprostol were 8.4 and 5.5 h, respectively. The incidence of side effects was low with no blood transfusions required., Conclusions: The success rate in this study is markedly below published data. This can possibly be attributed to retrospective study design, allowing for physician subjectivity and patients' wishes in the absence of strict study requirements. The protocol was well tolerated with a paucity of side effects. We make suggestions for enhancing success rates in the clinical setting by optimizing medication protocols, establishing precise treatment guidelines and training physicians in the accurate interpretation of treatment outcomes.

The incidence of fetal portosystemic anastomoses is unknown, and it is presumed that many cases remain undetected, as visualization of the hepatic vasculature is not part of the routine 20-week sonographic scan in pregnancy. However, portosystemic anastomoses are associated with fetal growth restriction due to a diminished oxygen supply to hepatocytes and, hence, downregulation of liver function. In these cases, uteroplacental perfusion might be normal.
