Neonatal weight measurements are used as a key indicator of breastfeeding adequacy. The purpose of this study was to explore non-feeding factors that might be related to newborn weight loss. The relationship between the intravenous (IV) fluids women receive during parturition (the act of giving birth including time in labour or prior to a cesarean section) and their newborn's weight loss during the first 72 hours postpartum was the primary interest. Three hypotheses guided the thesis. Specifically, the hypotheses stated that in the first 72 hours postpartum, there is a positive association between: (a) the amount of IV fluid given to a woman during parturition and the amount of weight her infant loses; (b) the amount of IV fluid given to a woman during parturition and the amount her infant eliminates; and (c) the amount an infant eliminates and the infant's weight loss. In an effort to clarify patterns of weight loss, a systematic review was completed to determine reference weight loss, and the results are reported in this thesis. Additionally, the issue of who should consent for neonates in lactation and breastfeeding research studies was raised during the ethics review, and the results of an examination of the underpinning principles for such consent are presented in this thesis. A prospective observational cohort study was conducted to explore associations between maternal fluids during parturition, neonatal output, and newborn weight loss. During labour or before a cesarean section, maternal IV and oral fluids were recorded. Participants weighed their newborns every 12 hours for 72 hours, then weight was measured daily from Day 4 to Day 14. Parents weighed all output (i.e. diapers) in the first 72 hours. Results of the systematic review show that the 7% maximum allowable weight loss recommended in four clinical practice guidelines appears to be based on mean weight loss and does not account for standard deviation. Although we determined patterns of weight loss, causes of weight loss and implications for morbidity and mortality were not established. Completing the systematic review clarified assumptions about how birth weight is used as the baseline for calculating weight loss and how clinical decisions are based on the percentage of loss from birth weight. The three hypotheses were supported. At 60 hours postpartum (point of maximum weight loss), mean loss was 237.2 grams (SD 98; n = 96, range 70-467 grams) and the percentage lost was 6.57 (SD 2.51; n = 96, range 1.83-13.06%). There was a positive relationship between maternal IV fluids from admission to birth and neonatal weight loss in grams (r(83) = .199, p = .035). Mean neonatal output for the first 24 hours was 83.04 grams (SD 47.81; n = 107, range 0-314 grams). There was a positive relationship between maternal IV fluids given in the final 2 hours before birth and neonatal output at 24 hours (r(17) = .426, p = .044) which explained 18% of the variability in weight loss. On Day 1, there was a positive relationship between output and weight loss (r(96) = .341, P < .0001) which explained 12% of the variability in weight loss. When groups, based on maternal fluids, were compared (≤1200 mls [n = 21] versus> 1200 [n =53]), newborns lost 5.51% versus 6.93% (p = 0.03). A hierarchical regression analysis indicated gestational age and birth weight were additional predictors of weight loss. It appears neonates experience diuresis in the first 24 hours with a related weight loss. Overall, the results indicate that maternal IV fluids before birth are related to weight loss in the early postpartum period. It appears neonate's experience varying degrees of diuresis, and consequent weight loss, in the first 24 hours is a correction. Clinicians (e.g. nurses, lactation consultants, and physicians working with breastfeeding women) should reconsider using birth weight as baseline when assessing newborn weight loss. These findings support using weight measured at 24 hours postpartum as the baseline for assessing newborn weight loss.

Background: Communicating double uterine anomalies are defined as mullerian defects which involve two hemiuteri with communication between the uterine halves. Nine subcategories of communicating uterine anomalies have been described; only two of these subcategories are associated with hemivaginal obstruction. Case: An 11-year-old white female was brought to the Emergency Department with fever and acute pelvic pain. This condition was found to be caused by abscess formation behind an obstructed left hemivagina with involvement of a communicating double uterine anomaly. Conclusion: To our knowledge, this is the first case report involving a communicating double uterine anomaly in which fever was a presenting symptom.

To determine if known androgenic hormone precursors for testosterone in the androgen pathway would be readily transformed to testosterone, eight male subjects [mean age 23.8 (SEM 3) years, bodymass 83.1 (SEM 8.7) kg, height 175.6 (SEM 8.5) cm] underwent a randomized, double-blind, cross-over, placebo-controlled oral treatment with 200 mg of 4-androstene-3,17-dione (Δ4), 4-androstene-3β,17β-diol (Δ4Diol), and placebo (PL). The periods of study were separated by 7 days of washout. Blood was drawn at baseline and subsequently every 30 min for 90 min after treatment. Analysis revealed mean area-under-the-curve (AUC) serum Δ4 concentrations to be higher during Δ4 treatment [2177 (SEM 100) nmol.l-1] than Δ4Diol [900 (SEM 96) nmol.l-1] or PL [484 (SEM 82) nmol.l-1; P < 0.0001]. The Δ4 treatment also revealed a significant effect on total testosterone with a mean AUC [1632.5 (SEM 121) nmol.l-1] that was greater than PL [1418.5 (SEM 131) nmol.l-1; P < 0.05] but not significantly different from those observed after Δ4Diol treatment [1602.9 (SEM 119) nmol.l-1; P = 0.77]. Free testosterone concentrations followed a similar pattern where mean AUC for the Δ4 treatment [6114.0 (SEM 600) pmol.l-1] was greater than after PL [4974.6 (SEM 565) pmol.l-1; P < 0.06] but not significantly different from those observed after Δ4Diol [5632.0 (SEM 389) pmol.l-1; P = 0.48]. The appearance and apparent conversion to total and free testosterone over 90 min was stronger for the Δ4 treatment (r = 0.91, P < 0.045) than for Δ4Diol treatment (r = 0.69, NS) and negatively correlated for PL (r = -0.90, P < 0.02). These results would suggest that Δ4, and perhaps Δ4Diol, taken by month are capable of producing in vivo increases in testosterone concentrations in apparently healthy young men as has already been observed in women after treatment with Δ4.

Individuals with Down syndrome have an increased risk formany conditions, including cardiovascular disease, cancer, infections, and osteoporosis, and endocrine, neurological, orthopedic, auditory, and ophthalmic disorders.They also are at increased risk for abuse and human rights violations and receive fewer screenings and interventions than the population without Down syndrome. In this literature review, the most common health conditions associated with Down syndrome are examined, along with the topics of sexual abuse, menstrual hygiene, contraception, and human rights. Clinical guidelines for this population are summarized in an effort to assist practicing physicians in improving their provision of health care to the adult patient with Down syndrome.

Glucans are fungal cell wall glucose polymers that are released into the blood of infected patients. The role of glucans in infection is unknown. We examined serum glucan and cytokine levels in intensive care unit (ICU) patients with infections. There was an inverse correlation (p<0.001) between serum glucan levels and interleukin (IL)-2), IL-4, tumor necrosis factorα (TNFα) and granulocyte macrophage-colony stimulating factor (GM-CSF) levels in infected ICU patients. The correlation between serum cytokines and serum glucan was only observed at glucan concentrations <40 pg/ml. No change was observed at serum glucan levels of >40 pg/ml. There was no correlation between serum glucan levels and systemic levels of IL-1β, IL-5, IL-6, IL-8, IL-10 or IFNγ. Interestingly, blood borne glucans did not suppress systemic cytokine levels in infected ICU patients, instead they were maintained at control levels. We conclude that circulating glucans may prevent cytokine upregulation in response to infection. This may represent an adaptive response to septic injury.

Background: Women with communicating double uterine anomalies are at increased risk for obstetric complications, including early pregnancy loss, preterm delivery, and breech presentation. We present the pregnancy of a woman with a previously diagnosed communicating double uterine anomaly. Case: An 18-yr-old white female with a previous diagnosis at age 11 of a communicating double uterus, double cervix, and obstructed left hemivagina was followed during the course of her pregnancy. She experienced no complications until 36 6/7 weeks, when she was found to have signs and symptoms of mild preeclampsia. The fetus was in a breech presentation and a cesarean section was performed. Two hemiuteri were identified intraoperatively. The communication was not visualized. A viable male infant was delivered without complications. Conclusion: This patient represents only the sixth report of successful pregnancy in a woman with a Toaff type 5A communicating uterine anomaly.

Objectives This study is a follow-up to previous research regarding buprenorphine medication-assisted therapy (MAT) in Johnson City, Tennessee. For-profit MAT clinics were surveyed to determine changes in tapering practice patterns and insurance coverage during the last 3 years. Methods Johnson City for-profit MAT clinics; also called office based opioid treatment centers, were surveyed by telephone. Clinic representatives were asked questions regarding patient costs for therapy, insurance coverage, counseling offered onsite, and opportunities for tapering while pregnant. Results All of the MAT clinics representatives indicated that tapering in pregnancy could be considered even though tapering in pregnancy is contrary to current national guidelines. Forty-three percent of the clinics now accept insurance as compared with 0% in the 2016 study. The average weekly cost per visit remained consistent. Conclusions The concept of tapering buprenorphine during pregnancy appears to have become a standard of care for this community, as representatives state it is offered at all of the clinics that were contacted. Representatives from three clinics stated the clinics require tapering, even though national organizations such as the American College of Obstetricians and Gynecologists and the American Society of Addiction Medicine do not recommend this approach. Although patients who have government or other insurance are now able to obtain buprenorphine with no expense at numerous clinics, the high cost for uninsured patients continues to create an environment conducive to buprenorphine diversion.

Until the sixteenth century, childbirth in England was the exclusive domain of women and was orchestrated by the female midwife. By the end of the seventeenth century, university-educated and church-approved male physicians were systematically beginning to usurp the midwife's role in the lying-in room and to gradually assume authority and power over the process of childbirth. Ultimately doctordominated childbirth threatened, and in some places accomplished, the displacement of the midwife. No one factor was responsible for the shift in delivery room personnel nor was the transition from female midwives to male obstetricians a "natural" one. This thesis looks at three factors which contributed to the success of the transition: first, midwifery practices and the criticism of them by male medical practitioners; second, the association of midwifery and witchcraft; and third, the failure of attempts, particularly in the seventeenth century, to educate and regulate midwives at a time when the male medical profession was doing just that.
