016 Marine Corps policy change decreased contraception use-29.6% to 24.4%, OR 0.78 (95% CI 0.70-0.88), long-acting reversible contraception use-14.6% to 7.3%, OR 0.39 (95%CI 0.31-0.48), and increased childbirth rates-8.0% to 9.6%, HR 1.26 (95%CI 1.03-1.55) among Marines compared to outcomes in the Army and Air Force over the same time period. CONCLUSION Basic training contraceptive policy influences contraception use among junior enlisted. Implementing best practices across the military may increase contraception use and decrease childbirth rates among junior enlisted. BACKGROUND An estimated 1.4 million people in the United States identify as transgender or non-binary (TNB), signifying that their gender identity does not correspond with their assigned sex at birth. Individuals assigned female at birth may seek gender-affirming hormone therapy with testosterone. No studies have directly examined ovulatory function in transmasculine individuals using injectable testosterone. OBJECTIVES Our primary objective was to determine the effect of testosterone on ovulatory suppression in transmasculine individuals. Secondary objectives were to determine predictors of ovulation in transmasculine individuals on testosterone, and to assess the effect of testosterone on AMH. STUDY DESIGN This prospective observational study recruited participants from a community clinic that provides gender affirming hormone therapy. Enrolled individuals were assigned female at birth and were currently using or seeking to initiate masculinizing therapy with injectable testosterone esters (transmasculine iividuals engaged in sexual intercourse with sperm-producing partners. Given the small number of overall participants, this work is hypothesis-generating. Larger studies are needed to confirm and clarify these findings. There is worldwide enthusiasm for the elimination of hepatitis C (HCV). The availability of highly effective and safe direct acting anti-viral agents to treat almost everyone with HCV infection means that HCV elimination is now primarily a public health challenge. Making progress towards HCV elimination requires screening to increase the proportion of HCV-infected persons who are aware of their status, linking to and retaining them in care to achieve cure, and increasing access to harm reduction services to prevent new infections. Historically, the majority of HCV-infected persons were "baby boomers" born during 1945-1965. selleckchem Since the Centers for Disease Control recommended one-time HCV screening of baby boomers in 2012, the HCV prevalence in that population has decline with many have been identified and treated. Concurrently, there has been an increase in HCV prevalence among young adults using injection drugs. An important consequence of this changing epidemiology has been an increase in the number of HCV-infected women of childbearing age and HCV-exposed infants. Developing comprehensive programs and policies to identify, treat, and prevent perinatal HCV-transmission will play an important role in achieving the public health goal of HCV elimination. BACKGROUND Planned home births have leveled off in the United States in the last years after a significant rise starting in the mid-2000s. Planned home births in the U.S. are associated with increased patient-risk profiles. Multiple studies concluded that, compared to hospital births, absolute and relative risks of perinatal mortality and morbidity in U.S. planned home births are significantly increased. OBJECTIVE The purpose of this study was to explore the safety of birth in the United States by comparing the neonatal mortality outcomes of two locations, hospital birth and home birth, by four types of attendants hospital midwife; certified nurse-midwife at home; direct-entry ("other") midwife at home; and attendant at home not identified, using the most recent U.S. Centers for Disease Control (CDC) natality data on neonatal mortality for planned home births in the United States. Outcomes are presented as absolute risks (neonatal mortality per 10,000 live births), and as relative risks of neonatal mortality ntry midwives or by certified nurse-midwives is not statistically significant. The centromere is a specialized chromosomal locus required for accurate chromosome segregation. Heterochromatin also assembles around centromere chromatin and forms a base that supports sister chromatid cohesion until anaphase begins. Both centromere chromatin and heterochromatin assemble on a centromeric DNA sequence, a highly repetitive sequence called alphoid DNA (α-satellite DNA) in humans. Alphoid DNA can form a de novo centromere and subsequent human artificial chromosome (HAC) when introduced into the human culture cells HT1080. HAC is maintained stably as a single chromosome independent of other human chromosomes. For de novo centromere assembly and HAC formation, the centromere protein CENP-B and its binding sites, CENP-B boxes, are required in the repeating units of alphoid DNA. CENP-B has multiple roles in de novo centromere chromatin assembly and stabilization and in heterochromatin formation upon alphoid DNA introduction into the cells. Here we review recent progress in human artificial chromosome construction and centromere/heterochromatin assembly and maintenance, focusing on the involvement of human centromere DNA and CENP-B protein. Centromeres are highly specialized genomic loci that function during mitosis to maintain genome stability. Formed primarily on repetitive α-satellite DNA sequence characterisation of native centromeric chromatin structure has remained challenging. Fortuitously, neocentromeres are formed on a unique DNA sequence and represent an excellent model to interrogate centromeric chromatin structure. This review uncovers the specific findings from independent neocentromere studies that have advanced our understanding of canonical centromere chromatin structure. Microbial contamination may compromise the efficacy and safety of pharmaceutical products. Microbial enumeration tests are required by most of the pharmacopeial compendia and consist in conventional pour-plate inoculation of a sample aliquot followed by incubation under appropriate conditions. Despite of this, the measurement uncertainty evaluation for microbial enumeration tests is rarely considered. Thus, the aim of this paper was to assess the matrix effects in microbial enumeration tests and their top-down uncertainty evaluation. Microbial counting methods for eighteen pharmaceutical products were validated concerning the trueness (mean recovery) and precision (repeatability and intermediate precision) using seven test microorganisms. Uncertainty factors values were found to be between 1.1 and 3.3, based on trueness and precision results. Trueness uncertainty component was the most relevant in 59% of the cases. This issue can be explained due to the matrix interference cause by preservatives or antimicrobial agents, particularly for lower dilutions when compared to higher dilutions.
