RESUMEN

Limited studies have determined the effects of modified atmospheric packaging (MAP) on atypical dark-cutting beef surface color. The objective was to compare the impacts of using vacuum packaging, carbon monoxide (CO-MAP), and HiOx-MAP (high­oxygen) on the retail color of normal-pH and atypical dark-cutting beef aged 14 d. Atypical dark-cutting beef (pH 5.63) had numerically greater (P > 0.05) pH than normal-pH beef (pH 5.56). Atypical dark-cutting steaks were darker in color (lower L* values; P < 0.05) than normal-pH steaks. Atypical dark-cutting steaks had greater (P < 0.05) oxygen consumption, lower (P < 0.05) relative oxygenation, and less inter-muscle bundle space (P < 0.05) than normal-pH steaks. There were no differences (P > 0.05) in redness between normal-pH and atypical dark-cutting steaks when packaged in HiOx-MAP. Although a minimal increase in pH was observed in atypical dark-cutting beef, steaks in CO-MAP had lower redness than normal-pH steaks.

RESUMEN

INTRODUCTION: Women make up 15% of the total number of practicing gastroenterology (GI) physicians in the US. Despite this disparity, only 33% of the current GI fellows are female. Increasing female GIs is a major goal of all four GI societies. It is known that gender disparity exists in the field of gastroenterology, and women are underrepresented in the leadership ranks and trainee level at academic programs. Whether an increase in female leadership in academic medicine is associated with an increase in female program directors and trainees is unknown. The aim of this study was to assess this relationship in GI. MATERIALS AND METHODS: Data were collected via a standardized protocol from all 173 US gastroenterology fellowship programs up until October 2018 from program websites and supplemented by online surveys completed by program coordinators. Any missing information was collected by calling the program coordinators. Data were collected on gender and academic rank of the program director, associate program director, division chief, chair of medicine, program size, academic center affiliation, number, and academic rank of female faculty and geographic region. The association was assessed using a Chi-square test or independent samples t test. RESULTS: In leadership positions, men were listed as comprising 86% of chairs, 82% of division chiefs, 76% of program directors and 63% of associate program directors. Forty-three percent of programs did not have female representation at any leadership level. The presence of a female program director or female associate program director was associated with an increase in the number of female fellows (4.03 vs 3.20; p = 0.076; 4.26 vs 3.36; p = 0.041), respectively. Overall, the presence of a female in any leadership position led to an increase in the number of female fellows (4.04 females vs 2.87 females; p = 0.007) enrolled in a program. If a GI division chief was male, the program director was more likely to be male as well (81% male vs. 18.8% female). Conversely, having a female division chief was likely to lead to a more equitable program director representation, 54% female to 48% male (p value < 0.0001, OR 5.03 95% CI 2.04-12.3). Furthermore, if either the internal medicine department chair or GI chief was female, the proportion of female program directors increased to 41% as compared to 19% if both were male (p value < 0.0001, OR 2.99 95% CI 1.34-6.6). CONCLUSION: Women are significantly underrepresented in the number of practicing gastroenterologists, at all levels of leadership in GI fellowship programs, and at the fellow level. Increasing the number of women in fellowship leadership positions is associated with an increase in female program directors and trainees. Per our knowledge, this is the first study to examine the relationship between female leadership in fellowship programs and the gender of trainees. Increasing female representation in leadership positions would not only address current gender disparity, but it may also increase the number of female future GI trainees.

RESUMEN

OBJECTIVE: To evaluate the value of fetal scalp blood sampling (FBS) as an adjunct test to cardiotocography, to predict adverse neonatal outcomes. STUDY DESIGN: A multicentre service evaluation observational study in forty-four maternity units in the UK. We collected data retrospectively on pregnant women with singleton pregnancy who received FBS in labour using a standardised data collection tool. The primary outcome was prediction of neonatal acidaemia diagnosed as umbilical cord arterial pH < 7.05, the secondary outcomes were the prediction of Apgar scores<7 at 1st and 5th minutes and admission to the neonatal intensive care unit (NICU). We evaluated the correlation between the last FBS blood gas before birth and the umbilical cord blood and adjusted for time intervals. We constructed 2 × 2 tables to calculate the sensitivity, specificity, positive (PPV) and negative predictive value (NPV) and generated receiver operating curves to report on the Area Under the Curve (AUC). RESULTS: In total, 1422 samples were included in the analysis; pH values showed no correlation (r = 0.001, p = 0.9) in samples obtained within an hour (n = 314), or within half an hour from birth (n = 115) (r=-0.003, p = 0.9). A suboptimal FBS pH value (<7.25) had a poor sensitivity (22%) and PPV (4.9%) to predict neonatal acidaemia with high specificity (87.3%) and NPV (97.4%). Similar performance was noted to predict Apgar scores <7 at 1st (sensitivity 14.5%, specificity 87.5%, PPV 23.4%, NPV 79.6%) and 5th minute (sensitivity 20.3%, specificity 87.4%, PPV 7.6%, NPV 95.6%), and admission to NICU (sensitivity 20.3%, specificity 87.5%, PPV 13.3%, NPV 92.1%). The AUC for FBS pH to predict neonatal acidaemia was 0.59 (95%CI 0.59-0.68, p = 0.3) with similar performance to predict Apgar scores<7 at 1st minute (AUC 0.55, 95%CI 0.51-0.59, p = 0.004), 5th minute (AUC 0.55, 95%CI 0.48-0.62, p = 0.13), and admission to NICU (AUC 0.58, 95%CI 0.52-0.64, p = 0.002). Forty-one neonates had acidaemia (2.8%, 41/1422) at birth. There was no significant correlation in pH values between the FBS and the umbilical cord blood in this subgroup adjusted for sampling time intervals (r = 0.03, p = 0.83). CONCLUSIONS: As an adjunct tool to cardiotocography, FBS offered limited value to predict neonatal acidaemia, low Apgar Scores and admission to NICU.

RESUMEN

OBJECTIVES: Double-guidewire cannulation (DGC) for selective biliary access has been associated with increased risk of post-ERCP pancreatitis (PEP) in patients who have had pancreatic duct (PD) contrast injection. The objective of this study was to determine whether DGC increases PEP risk in standard risk individuals when controlling for procedural aspects such as PD contrast injection. METHODS: Consecutive adults with native papillae who underwent endoscopic retrograde cholangiopancreatography from 2009 to 2014 were retrospectively identified, and clinical data were collected. RESULTS: There were 879 subjects who met inclusion criteria. Increased incidence of PEP was observed after DGC (18% with DGC vs 4% without DGC, P < 0.005). Additional factors associated with increased PEP risk included the following: PD contrast injection, PD wire cannulations, and biliary stent placement. The association between DGC and increased PEP risk remained significant in a multivariate model controlling for age, sex, PD contrast injection, biliary sphincterotomy, biliary stent placement, and rectal indomethacin administration (odds ratio = 2.87, 95% confidence interval = 1.23-6.36). CONCLUSIONS: Double-guidewire cannulation is associated with increased risk of PEP when controlling for confounding variables. Prospective studies should be undertaken to assess whether prophylactic interventions reduce risk of PEP after DGC in an average-risk population.

RESUMEN

Fibroids are a condition commonly seen as part of routine gynaecological practice and generally present with menorrhagia, infertility, or pressure symptoms depending on their exact location. We report the case of a postmenopausal 57-year-old lady presenting with left-sided pain and frequency with a complex 15 cm mass mid pelvis and an adjacent additional 7 cm cyst but a risk of malignancy index suggesting benign pathology. She underwent total abdominal hysterectomy (TAH) and right-sided salpingo-oophrectomy (RSO) on recommendation of the multidisciplinary team (MDT) and histology confirmed leiomyomatosis peritonealis disseminata. This rare but important condition is often confused with peritoneal carcinomatosis on imaging. The mainstay of treatment involves lesion and omental excision followed by removal of hormonal stimuli although this approach must be personalised as many younger women may wish to retain their uteri. Long-term follow-up is essential due to the potential for malignant transformation.
