PURPOSE: To analyze the effect of partial compliance on preterm birth (PTB) prevention among women with previous PTB and receiving 17 alpha-hydroxyprogesterone caproate (17-OHPC). STUDY DESIGN: This is a secondary analysis of a multicenter trial for the prevention of recurrent PTB. Women with prior PTB were randomly assigned between 15 0/7 and 20 3/7 weeks to weekly injections of either 17-OHPC or placebo. Full 100% compliance (group 1) was compared to 40-80% (group 2)...

OBJECTIVES: Estimating gestational age is usually based on date of last menstrual period (LMP) or clinical estimation (CE); both approaches introduce potential bias. Differences in methods of estimation may lead to misclassification and inconsistencies in risk estimates, particularly if exposure assignment is also gestation-dependent. This paper examines a 'what-if' scenario in which alternative methods are used and attempts to elucidate how method choice affects observed results. METHODS: We constructed two 20-week gestational age cohorts of pregnancies between 2000 and 2005 (New Jersey, Pennsylvania, Ohio, USA) using live birth certificates: one defined preterm birth (PTB) status using CE and one using LMP...

OBJECTIVES: We examined the association of an array of estimated maternal occupational physical activities and psychosocial stressors during pregnancy with odds for preterm birth (PTB) and small-for-gestational age (SGA). METHODS: Data for infants born without major birth defects delivered from 1997 to 2009 whose mothers reported working at least 1 month during pregnancy were obtained from the National Birth Defects Prevention Study. We linked occupational codes to the US Department of Labor's Occupational Information Network, which provides estimates of exposure for multiple domains of physical activity and psychosocial stressors by occupational categories...

Preterm birth (PTB) is a leading cause of neonatal death worldwide. Intrauterine and systemic infection and inflammation cause 30-40% of spontaneous preterm labor (PTL), which precedes PTB. Although antibody production is a major immune defense mechanism against infection, and B cell dysfunction has been implicated in pregnancy complications associated with PTL, the functions of B cells in pregnancy are not well known. We found that choriodecidua of women undergoing spontaneous PTL harbored functionally altered B cell populations...

PURPOSE: Pakistan is faced with an increasing prevalence of diabetes in addition to its existing high burden of tuberculosis (TB). Diabetes has a detrimental effect on treatment outcomes of patients with TB, which may hinder achieving the goals of the End-TB strategy by 2030. We conducted a prospective cohort study to determine difference between treatment outcomes among patients with diabetes and new pulmonary tuberculosis (PTB) and patients without diabetes and new PTB. This would help generate contextual and valid scientific evidence from a developing country like Pakistan with its unique interplay of sociocultural, economic and health system factors to inform policy and practice...

OBJECTIVE: For long-term electrocardiography (ECG) recordings, accurate R-wave detection is essential. Several algorithms have been proposed but not yet compared on large, noisy, or pathological data, since manual ground truth establishment is impossible on such large data. METHODS: We apply the simultaneous truth and performance level estimation (STAPLE) method to ECG signals comparing 9 R-wave detectors: Pan & Tompkins (1985), Chernenko (2007), Arzeno et al. (2008), Manikandan et al...

Human dermal fibrotic disease keloid has been a clinical challenge because of its tumour-like growth and the lack of effective therapy. Dysregulated alternative splicing events have been demonstrated in tumours and fibrosis. In the current study, for the first time, it was demonstrated that the splicing regulator polypyrimidine tract-binding protein (PTB), which plays a pivotal role in tumour proliferation, invasion and metastasis, is overexpressed in keloid tissues and fibroblasts. Additionally, TGF-β1 upregulated the expressions of PTB and its upstream regulator, C-MYC, in keloid fibroblasts...

SETTING: Although there is ample evidence that smoking increases the risk of tuberculosis (TB), the magnitude of impact on TB risk among HIV-infected persons is poorly described. Given that a high proportion of patients with TB are co-infected with HIV in South Africa, the risks arising from the intersection of smoking, TB, and HIV/AIDS have key relevance for tobacco control policies. OBJECTIVE: To evaluate the association of pulmonary tuberculosis (PTB) with current tobacco smoking among men with HIV in South Africa...

RIG-I-like receptors (RLRs) can recognize viral RNA and initiate innate antiviral response. In earlier studies, we demonstrated that RLRs were implicated in the antiviral immunity against RGNNV in the seawater fish sea perch (Lateolabrax japonicus). However, potential regulators of RLRs-mediated signaling pathways involved in RGNNV infection remain unclear. In this study, a novel ribonucleoprotein PTB-binding 1 (Raver1) of sea perch (LjRAVER1) was identified for the first time. The cDNA of LjRAVER1 was 4066 bp in length and encoded a deduced polypeptide of 733 amino acids...

Little is understood about racial/ethnic disparities in infant health in South America. We quantified the extent to which the disparity in preterm birth (PTB; <37 gestational weeks) rate between infants of Native only ancestry and those of European only ancestry in Argentina and Ecuador are explained by household socio-economic, demographic, healthcare use, and geographic location indicators. The samples included 5199 infants born between 2000 and 2011 from Argentina and 1579 infants born between 2001 and 2011 from Ecuador...

Cellular organization and response to internal and external stimuli are mediated by an intricate web of protein interactions. Some of these interactions are regulated by covalent posttranslational modifications such as phosphorylation and acetylation. These modifications can change the chemical nature of the interaction interfaces and modulate the binding affinity of the interacting partners. In signal transduction, the most frequent modification is reversible phosphorylation of tyrosine, serine or threonine residues...

BACKGROUND: Women with at least 1 prior occurrence of premature birth often have demographic and medical risk factors that are not modifiable. However, smoking cessation could be a targeted intervention in which a woman with a history of premature birth may be able to reduce her future risk of recurrence. OBJECTIVE: This study aims to assess how trimester-specific smoking patterns influence the risk of recurrent premature birth. STUDY DESIGN: This was a population-based retrospective cohort study of singleton nonanomalous live births in Ohio, 2006-2012 using vital statistics birth records...

INTRODUCTION: Higher adult socioeconomic position (SEP) is associated with better birth outcomes. However, few studies incorporate life-course or intergenerational SEP, which may inform etiology and targeted prevention efforts. This study tested whether life-course social mobility from childhood was associated with lower risk of adverse birth outcomes. METHODS: Data were from the Life-course Influences of Fetal Environments (LIFE) retrospective cohort study among black women, 2009-2011, in metropolitan Detroit, MI...
