Differences in Surgical Complications for Stage 1 Phalloplasty With Concurrent Versus Asynchronous Hysterectomy in Transmasculine Patients.

Background The authors sought to compare the perioperative morbidity of Stage 1 phalloplasty with asynchronous vs concurrent hysterectomy among transmasculine patients. Methods This retrospective study included transmasculine patients undergoing Stage 1 phalloplasty with either asynchronous or concurrent hysterectomy at Kaiser Permanente Northern California from January 1, 2017, to September 9, 2019. The primary outcome was differences in surgical site infection rates. Secondary outcomes included perioperative and other postoperative complications. Comparisons of demographics and outcomes were made by F-tests and Fisher's exact tests. A p value of < 0.05 was considered statistically significant. Results Of 66 transmasculine patients undergoing Stage 1 phalloplasty, 32 (48%) had an asynchronous hysterectomy and 34 (52%) had a concurrent hysterectomy. Overall, surgical site infection rates were low, and there were no significant differences between groups. Patients who had undergone asynchronous hysterectomy had more neourethral complications with Stage 1 phalloplasty than those undergoing concurrent procedures (28% vs 3%, p < 0.05). There were no significant differences in estimated blood loss, length of stay, urinary tract infection, overactive bladder or narcotic use between groups. Conclusion Overall, there were no differences between groups in most postoperative complication rates. Although more neourethral complications were found in those undergoing asynchronous hysterectomy prior to Stage I phalloplasty, this may be partially explained by increasing surgeon experience over time given this difference did not remain statistically significant after the first year of the study period. Gynecologists seeking to provide comprehensive and inclusive care to transmasculine patients should take these findings into consideration when counseling patients planning genital gender affirmation surgery.

Serum Ferritin Threshold for Iron Deficiency Screening in One-Year-Old Children.

The American Academy of Pediatrics recommends universal hemoglobin screening for iron deficiency anemia using hemoglobin <110 g/L at the 1-year-old well child visit. Our retrospective study suggests the need for combined hemoglobin and serum ferritin iron deficiency screening and raising the diagnostic serum ferritin threshold to 24-25 µg/L.

Healthcare utilization following minimally invasive apical prolapse repair in a large integrated healthcare system.

INTRODUCTION AND HYPOTHESIS: We sought to describe healthcare utilization (HU) following minimally invasive apical prolapse repair (MIAR) and its association with duration of hospital stay, patient characteristics, and perioperative factors. METHODS: This retrospective study included women undergoing MIAR within a large managed care organization between January 1, 2011, and June 30, 2018, and aimed to quantify HU within 30 days of surgery. HU was dichotomized into two groups: normal and high, based on typical postoperative utilization of healthcare resources. The primary outcome was the rate of normal versus high HU overall and by duration of hospital stay [discharge home on day of surgery versus postoperative day (POD) 1-2]. Multivariable logistic regression was performed to identify factors predictive of high HU. A p value of < 0.05 was considered statistically significant. RESULTS: Of the 4208 patients in our final cohort, 17% had high HU, while 83% were normal utilizers. High utilizers were more likely to have multiple comorbidities (p < 0.01) and a diagnosis of chronic pelvic pain (p = 0.02) and were less likely to be discharged on day of surgery (p < 0.01). A higher burden of disease, a concurrent mid-urethral sling or posterior colporrhaphy, and discharge on POD 1-2 were independently predictive of high HU. Within the high HU cohort, the most common type of unanticipated healthcare encounter was emergency department visit for urinary retention or pain. CONCLUSIONS: Same-day discharge after MIAR does not result in increased HU, even after adjusting for relevant demographic and clinical characteristics. Pre-existing chronic pain diagnoses, multiple comorbidities, and concurrent mid-urethral sling are associated with high HU in this population.

Progesterone Supplementation for the Prevention of Preterm Birth: Provider Practice in Wisconsin.

OBJECTIVE: To assess provider practice patterns on type of progesterone prescribed and barriers specific to 17 α-hydroxyprogesterone caproate utilization for preterm birth prevention. STUDY DESIGN: A survey mailed to providers assessed utilization and barriers to long-acting reversible contraception and progesterone for preterm birth prevention. Data analysis included chi-square tests for homogeneity followed by post hoc tests of proportions to detect significant pairwise differences. RESULTS: Five hundred sixty-three of 1,695 respondents who provide prenatal care were included in the analysis. More obstetric than family medicine and midwife providers (87.4% vs 31.4% and 72.6%, respectively; P < .001) prescribed any progesterone for preterm birth prevention. More obstetric providers prescribed 17a-hydroxyprogesterone caproate (17OHP-C) compared with family medicine and midwife providers (98.1% vs 77.8% and 80.5%, respectively; P < .0001). Family medicine and midwife providers prescribed oral progestertone more often than obstetric providers (40.7% and 24.4% vs 13.1 %; P < .05). System-level barriers to 17OHP-C were reported more often than patient-level barriers at a rate that was highest among family medicine and midwife providers. CONCLUSION: 17OHP-C has been demonstrated to be an effective method for prevention of recurrent preterm birth. It is used significantly less-and oral progesterone is used significantly more-by family medicine and midwife providers, emphasizing the need for increased education and decreased treatment barriers for its utilization for preterm birth prevention.

Improving Rates of Screening for Anemia in Infancy.

In 2010, the American Academy of Pediatrics recommended universal screening for anemia at approximately 1 year of age. This quality improvement study sought to improve anemia screening in an ambulatory setting. In a large university-based setting, a best practice alert (BPA) was placed within the electronic health record. The primary outcome was overall screening rate in ambulatory family medicine (DFM) and pediatrics (PEDS) clinics. From 2545 pre-BPA clinic visits over a 12-month period, the screening rate was 48.2%. Among 2186 post-BPA clinic visits over an 8-month period, the screening rate improved to 72.7%, P < .0001. Follow-up over a second 7-month period demonstrated sustained improvements (70.8%) but was not higher after educational sessions between the periods. Screening rates were higher in PEDS than DFM at each time point; P < .0001. This technology-based intervention increased and maintained higher screening rates for anemia at 1 year, with higher rates in PEDS.

Maternal Obesity Affects Inflammatory and Iron Indices in Umbilical Cord Blood.

OBJECTIVE: To determine the impact of maternal obesity and gestational weight gain across pregnancy on fetal indices of inflammation and iron status. STUDY DESIGN: Eighty-five healthy term newborns delivered via elective cesarean were categorized by 2 maternal body mass index (BMI) thresholds; above or below 30 kg/m(2) or above or below 35 kg/m(2). Umbilical cord plasma levels of C-reactive protein, interleukin (IL)-6, tumor necrosis factor (TNF)-α, ferritin, and hepcidin were assayed. Cytokines released by phytohemagglutinin-stimulated umbilical cord mononuclear cells (MNCs) were assayed. RESULTS: Maternal class II obesity, defined as BMI of 35 kg/m(2) and above, predicted higher C-reactive protein and TNF-α in umbilical cord plasma (P < .05 for both), and also proinflammatory cytokines (IL-1ß, IL-6, and TNF-α) from stimulated MNC (P < .05 for all). The rise in plasma TNF-α and MNC TNF-α was not linear but occurred when the threshold of BMI 35 kg/m(2) was reached (P < .005, P < .06). Poorer umbilical cord iron indices were associated with maternal obesity. When ferritin was low, IL-6 was higher (P < .04), but this relationship was present primarily when maternal BMI exceeded 35 kg/m(2) (P < .03). Ferritin was correlated with hepcidin (P < .0001), but hepcidin was unrelated to either maternal BMI or inflammatory indices. CONCLUSIONS: Class II obesity and above during pregnancy is associated with fetal inflammation in a threshold fashion. Although maternal BMI negatively impacted fetal iron status, hepcidin, related to obesity in adults, was related to iron status and not obesity in fetuses. Pediatricians should be aware of these relationships.

Cassava Intake and Vitamin A Status among Women and Preschool Children in Akwa-Ibom, Nigeria.

BACKGROUND: As part of the HarvestPlus provitamin A-biofortified cassava program in Nigeria we conducted a survey to determine the cassava intake and prevalence of vitamin A deficiency among children 6-59 months and women of childbearing age in the state of Akwa Ibom. METHODS: A cluster-randomized cross-sectional survey was conducted in 2011 in Akwa Ibom, Nigeria. The usual food and nutrient intakes were estimated using a multi-pass 24-hour recall with repeated recall on a subsample. Blood samples of children and women were collected to analyze for serum retinol, serum ferritin, and acute phase proteins as indicators of infection. Vitamin A deficiency was defined as serum retinol <0.70 µmol/L adjusted for infection. RESULTS: A total of 587 households of a mother-child dyad participated in the dietary intake assessment. Cassava was very widely consumed in Akwa Ibom, mainly as gari or foofoo. Daily cassava consumption frequency was 92% and 95% among children and women, respectively. Mean (±SD) cassava intake (expressed as raw fresh weight) was 348 ± 317 grams/day among children and 940 ± 777 grams/day among women. Intakes of most micronutrients appeared to be adequate with the exception of calcium. Median vitamin A intake was very high both for children (1038 µg RAE/day) and women (2441 µg RAE/day). Red palm oil and dark green leafy vegetables were the main sources of vitamin A in the diet, with red palm oil alone contributing almost 60% of vitamin A intake in women and children. Prevalence of vitamin A deficiency ranged from moderate (16.9 %) among children to virtually non-existent (3.4 %) among women. CONCLUSION: Consumption of cassava and vitamin A intake was high among women and children in Akwa Ibom with a prevalence of vitamin A deficiency ranging from moderate in children to non-existent among women. The provitamin A biofortified cassava and other vitamin A interventions should focus dissemination in states where red palm oil is not widely consumed.

Carotenoid retention of biofortified provitamin A maize (Zea mays L.) after Zambian traditional methods of milling, cooking and storage.

Provitamin A biofortified maize hybrids were developed to target vitamin A deficient populations in Africa. The purpose of this study was to evaluate the degradation of carotenoids after milling, cooking, and storage among biofortified varieties released in Zambia. The biofortified maize hybrids contained 7.5 to 10.3 µg/g dry weight (DW) of provitamin A as measured by ß-carotene equivalents (BCE). There was virtually no degradation due to milling. The BCE retention was also high (>100%) for most genotypes when the maize was cooked into thick (nshima) and thin porridge, but showed a lower BCE retention (53-98%) when cooked into samp (dehulled kernels). Most of the degradation occurred in the first 15 days of storage of the maize as kernels and ears (BCE retention 52-56%) which then stabilized, remaining between 30% and 33% of BCE after six months of storage. In conclusion, most of the provitamin A degradation in biofortified maize hybrids occurred during storage compared with cooking and the magnitude of this effect varied among genotypes.

Static magnetic field exposure reproduces cellular effects of the Parkinson's disease drug candidate ZM241385.

BACKGROUND: This study was inspired by coalescing evidence that magnetic therapy may be a viable treatment option for certain diseases. This premise is based on the ability of moderate strength fields (i.e., 0.1 to 1 Tesla) to alter the biophysical properties of lipid bilayers and in turn modulate cellular signaling pathways. In particular, previous results from our laboratory (Wang et al., BMC Genomics, 10, 356 (2009)) established that moderate strength static magnetic field (SMF) exposure altered cellular endpoints associated with neuronal function and differentiation. Building on this background, the current paper investigated SMF by focusing on the adenosine A(2A) receptor (A(2A)R) in the PC12 rat adrenal pheochromocytoma cell line that displays metabolic features of Parkinson's disease (PD). METHODOLOGY AND PRINCIPAL FINDINGS: SMF reproduced several responses elicited by ZM241385, a selective A(2A)R antagonist, in PC12 cells including altered calcium flux, increased ATP levels, reduced cAMP levels, reduced nitric oxide production, reduced p44/42 MAPK phosphorylation, inhibited proliferation, and reduced iron uptake. SMF also counteracted several PD-relevant endpoints exacerbated by A(2A)R agonist CGS21680 in a manner similar to ZM241385; these include reduction of increased expression of A(2A)R, reversal of altered calcium efflux, dampening of increased adenosine production, reduction of enhanced proliferation and associated p44/42 MAPK phosphorylation, and inhibition of neurite outgrowth. CONCLUSIONS AND SIGNIFICANCE: When measured against multiple endpoints, SMF elicited qualitatively similar responses as ZM241385, a PD drug candidate. Provided that the in vitro results presented in this paper apply in vivo, SMF holds promise as an intriguing non-invasive approach to treat PD and potentially other neurological disorders.
