Breastfeeding Rates in the Military Are Unchanged Before and After the Onset of the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic brought changes in clinical operations and raised concerns about breastfeeding safety. We investigated the change in breastfeeding rates within a military population, a model of universal health care coverage, and elucidated factors that enhance or deter breastfeeding. Methods: A retrospective analysis was performed on mothers delivering infants ≥35 weeks' gestation at a military treatment facility (MTF) before (PRE) and during (PERI) the pandemic. Demographic data and feeding methods (exclusive, any, and no breastfeeding) from birth to 6 months of life were obtained. The primary outcome compared the breastfeeding rates between PRE and PERI. Logistic regressions identified factors associated with breastfeeding. Results: Of the 372 dyads, 189 (51%) were in PRE and 183 (49%) were in PERI. Exclusive breastfeeding rates in the nursery (77% versus 78%, p = 0.7), at 1 month (70% versus 65%, p = 0.3), at 2 months (65% versus 62%, p = 0.6), 4 months (49% versus 56%, p = 0.2), and 6 months of life (42% versus 47%, p = 0.5) were similar between PRE and PERI. Trends for any breastfeeding were also unchanged. Interactions with a lactation consultant were most strongly associated with exclusive breastfeeding in the nursery (odds ratio 21.88, confidence interval 5.84-82.00, p < 0.001). Discussion: Breastfeeding rates from birth to 6 months of life in infants receiving care at a single MTF were unchanged before and during the pandemic. Access to lactation consultants appears to be a significant contributing factor, and universal health care coverage may have improved access to this resource. Accessibility to breastfeeding resources and education is essential to support and strengthen breastfeeding within the military community.

Regional, Racial, and Mortality Disparities Associated With Neurosurgeon Staffing at Level I Trauma Centers.

BACKGROUND: Traumatic brain injury (TBI) occurs in approximately 30% of trauma patients. Because neurosurgeons hold expertise in treating TBI, increased neurosurgical staffing may improve patient outcomes. We hypothesized that TBI patients treated at level I trauma centers (L1TCs) with ≥3 neurosurgeons have a decreased risk of mortality vs. those treated at L1TCs with <3 neurosurgeons. METHODS: The Trauma Quality Improvement Program database (2010-2016) was queried for patients ≥18 years with TBI. Patient characteristics and mortality were compared between ≥3 and <3 neurosurgeon-staffed L1TCs. A multivariable logistic regression analysis was used to identify risk factors associated with mortality. RESULTS: Traumatic brain injury occurred in 243 438 patients with 5188 (2%) presenting to L1TCs with <3 neurosurgeons and 238 250 (98%) to L1TCs with ≥3 neurosurgeons. Median injury severity score (ISS) was similar between both groups (17, P = .09). There were more Black (37% vs. 12%, P < .001) and Hispanic (18% vs. 12%, P < .001) patients in the <3 neurosurgeon group. Nearly 60% of L1TCs with <3 neurosurgeons are found in the South. Mortality was higher in the <3 vs. the ≥3 group (12% vs. 10%, P < .001). Patients treated in the <3 neurosurgeon group had a higher risk for mortality than those treated in the ≥3 neurosurgeon group (odds ratio (OR) 1.13, 95% confidence intervals (CI) 1.01-1.26, P = .028). DISCUSSION: There exists a significant racial disparity in access to neurosurgeon staffing with additional disparities in outcomes based on staffing. Future efforts are needed to improve this chasm of care that exists for trauma patients of color.

Outcomes after pneumonectomy versus limited lung resection in adults with traumatic lung injury.

Pneumonectomy after traumatic lung injury (TLI) is associated with shock, increased pulmonary vascular resistance, and eventual right ventricular failure. Historically, trauma pneumonectomy (TP) mortality rates ranged between 53 and 100%. It is unclear if contemporary mortality rates have improved. Therefore, we evaluated outcomes associated with TP and limited lung resections (LLR) (i.e., lobectomy and segmentectomy) and aimed to identify predictors of mortality, hypothesizing that TP is associated with greater mortality versus LLR. We queried the Trauma Quality Improvement Program (2010-2016) and performed a multivariable logistic regression to determine the independent predictors of mortality in TLI patients undergoing TP versus LLR. TLI occurred in 287,276 patients. Of these, 889 required lung resection with 758 (85.3%) undergoing LLR and 131 (14.7%) undergoing TP. Patients undergoing TP had a higher median injury severity score (26.0 vs. 24.5, p = 0.03) but no difference in initial median systolic blood pressure (109 vs. 107 mmHg, p = 0.92) compared to LLR. Mortality was significantly higher for TP compared to LLR (64.9% vs 27.2%, p < 0.001). The strongest independent predictor for mortality was undergoing TP versus LLR (OR 4.89, CI 3.18-7.54, p < 0.001). TP continues to be associated with a higher mortality compared to LLR. Furthermore, TP is independently associated with a fivefold increased risk of mortality compared to LLR. Future investigations should focus on identifying parameters or treatment modalities that improve survivability after TP. We recommend that surgeons reserve TP as a last-resort management given the continued high morbidity and mortality associated with this procedure.

The impact of green tea polyphenols on development and reproduction in Drosophila melanogaster.

Although, green tea has numerous health benefits, adverse effects with excessive consumption have been reported. Using Drosophila melanogaster, a decrease in male fertility with green tea was evidenced. Here, the extent of green tea toxicity on development and reproduction was investigated. Drosophila melanogaster embryos and larvae were exposed to various doses of green tea polyphenols (GTP). Larvae exposed to 10 mg/mL GTP were slower to develop, emerged smaller, and exhibited a dramatic decline in the number of emerged offspring. GTP protected flies against desiccation but sensitized them to starvation and heat stress. Female offspring exhibited a decline in reproductive output and decreased survival while males were unaffected. GTP had a negative impact on reproductive organs in both males and females (e.g., atrophic testes in males, absence of mature eggs in females). Collectively, the data show that high doses of GTP adversely affect development and reproduction of Drosophila melanogaster.
