Nasrin Akhter, Amarda Shehu
Due to the essential role that the three-dimensional conformation of a protein plays in regulating interactions with molecular partners, wet and dry laboratories seek biologically-active conformations of a protein to decode its function. Computational approaches are gaining prominence due to the labor and cost demands of wet laboratory investigations. Template-free methods can now compute thousands of conformations known as decoys, but selecting native conformations from the generated decoys remains challenging...

BACKGROUND: Programmed intermittent boluses of local anesthetic have been shown to be superior to continuous infusions for maintenance of labor analgesia. High-rate epidural boluses increase delivery pressure at the catheter orifice and may improve drug distribution in the epidural space. We hypothesized that high-rate drug delivery would improve labor analgesia and reduce the requirement for provider-administered supplemental boluses for breakthrough pain. METHODS: Nulliparous women with a singleton pregnancy at a cervical dilation of less than or equal to 5 cm at request for neuraxial analgesia were eligible for this superiority-design, double-blind, randomized controlled trial...

Monitoring of the fetal condition during labor is currently performed by cardiotocography (CTG). Despite the use of CTG in clinical practice, CTG interpretation suffers from a high inter- and intra-observer variability and a low specificity. In addition to CTG, analysis of fetal heart rate variability (HRV) has been shown to provide information on fetal distress. However, fetal HRV can be strongly influenced by uterine contractions, particularly during the second stage of labor. Therefore, the aim of this study is to examine if distinguishing contractions from rest periods can improve the detection rate of HRV features for fetal distress during the second stage of labor...

This paper examines associations between labor market participation of Chilean mothers and the cognitive, language, and socio-economic development of their children. Using a nationally-representative sample of 3-year-old children, we test if mothers' work intensity in the two previous years is associated with child development outcomes; data were collected in 2010 when children were one year old, and again in 2012, when they were three years old. We find that children who were three years old with mothers who worked for higher fractions of their children's lives in the previous two years perform significantly better on all tests (cognitive, language, socio-emotional) than children whose mothers had worked less, while controlling for baseline test performance...

There is a well-documented negative correlation between unemployment and health. Yet, little research has examined how unemployment relates to participation in physical activity, and few researchers have considered how an individual's unemployment may affect the health of their spouse or partner. The purpose of this study is to answer three questions: 1. Is one's own unemployment associated with changes in physical activity participation? 2. Is one's partner's unemployment associated with changes in physical activity participation? 3...

This study investigated the relationship between women's disadvantage in mental health and physical functioning and gender differences in career backgrounds. Sexual division of labor persists and key career characteristics are overrepresented in women: low-skilled first job, downward occupational trajectory, interruptions. These interrelated characteristics are usually linked to poor health. Their overrepresentation in women may be related to the female-male health gap; however, it may not if overrepresentation transposed into substantially weaker associations with poor health outcomes...

Accumulating evidences have indicated that lncRNAs play an important role in various human complex diseases. However, known disease-related lncRNAs are still comparatively small in number, and experimental identification is time-consuming and labor-intensive. Therefore, developing a useful computational method for inferring potential associations between lncRNAs and diseases has become a hot topic, which can significantly help people to explore complex human diseases at the molecular level and effectively advance the quality of disease diagnostics, therapy, prognosis and prevention...

BACKGROUND: The major causes of maternal and neonatal mortality in the Philippines are hemorrhages and obstructed labor due to placental implantation abnormalities (PIAs), twin pregnancies and fetal malpresentations. All of which are all easily detected by ultrasound. However, women in rural areas and low-income groups do not have access to ultrasound during their prenatal care. We aimed to provide additional evidence on the benefits of handheld ultrasound (HU) for screening pregnancy related abnormalities in order to avert maternal and neonatal deaths...

BACKGROUND: The use of centrifugation-based approaches for processing donated blood into components is routine in the industrialized world, as disparate storage conditions require the rapid separation of 'whole blood' into distinct red blood cell (RBC), platelet, and plasma products. However, the logistical complications and potential cellular damage associated with centrifugation/apheresis manufacturing of blood products are well documented. The objective of this study was to evaluate a proof-of-concept system for whole blood processing, which does not employ electromechanical parts, is easily portable, and can be operated immediately after donation with minimal human labor...

BACKGROUND: Proper collection and storage of fecal samples is necessary to guarantee the subsequent reliability of DNA-based soil-transmitted helminth diagnostic procedures. Previous research has examined various methods to preserve fecal samples for subsequent microscopic analysis or for subsequent determination of overall DNA yields obtained following DNA extraction. However, only limited research has focused on the preservation of soil-transmitted helminth DNA in stool samples stored at ambient temperature or maintained in a cold chain for extended periods of time...

Synthetic oxytocin (sOT) is widely used during labor, yet little is known about its effects on fetal brain development despite evidence that it reaches the fetal circulation. Here, we tested the hypothesis that sOT would affect early neurodevelopment by investigating its effects on neural progenitor cells (NPC) from embryonic day 14 rat pups. NPCs expressed the oxytocin receptor (OXTR), which was downregulated by 45% upon prolonged treatment with sOT. Next, we examined the effects of sOT on NPC death, apoptosis, proliferation, and differentiation using antibodies to NeuN (neurons), Olig2 (oligodendrocytes), and GFAP (astrocytes)...

BACKGROUND: Treatment of pleural infection with instillation of sequential intrapleural tissue plasminogen activator (tPA) and human recombinant deoxyribonuclease (DNase) twice daily for a total of 6 doses has been shown to decrease surgical referral and improve radiographic imaging. This labor-intensive regimen was empirically chosen. Thus, it remains unclear whether the 2 drugs can be administered immediately one after the other (concurrent administration) instead of instilling them separately with a 1-hour to 2-hour interval in between (sequential administration)...

The UN Sustainable Development Goals of 2015 have restored universal health coverage (UHC) to prominence in the international health agenda. Can understanding the past illuminate the prospects for UHC in the present? This article traces an earlier history of UHC as an objective of international health politics. Its focus is the efforts of the International Labor Organization (ILO), whose Philadelphia Declaration (1944) announced the goal of universal social security, including medical coverage and care. After World War II, the ILO attempted to enshrine this in an international convention, which nation states would ratify...

BACKGROUND: Endometritis is a postpartum complication that is more common after cesarean delivery. It frequently requires intravenous antibiotic administration, prolonged hospital stays, and carries a risk of sepsis or abscess formation. Precesarean vaginal preparation has been shown to decrease the risk of endometritis in patients who have labored or have ruptured membranes. OBJECTIVE: The objective of this study was to assess the practical implementation of a protocol for vaginal cleansing prior to cesarean delivery and the subsequent effect on endometritis rates in a clinical setting...

Deep Learning has boosted artificial intelligence over the past 5 years and is seen now as one of the major technological innovation areas, predicted to replace lots of repetitive, but complex tasks of human labor within the next decade. It is also expected to be 'game changing' for research activities in pharma and life sciences, where large sets of similar yet complex data samples are systematically analyzed. Deep learning is currently conquering formerly expert domains especially in areas requiring perception, previously not amenable to standard machine learning...

This article analyzes a contradiction facing efforts by left-leaning governments in Latin America to transform health into a fundamental social right. Policies and practices that confront health inequities generally fail to address health/communicative inequities, hierarchical distributions of rights to shape what counts as legitimate knowledge of health. This ethnographic analysis focuses on an epidemic of a mysterious disease - identified clinically as bat-transmitted rabies - in the Delta Amacuro rainforest of Venezuela in 2007-2008, tracing how parents who lost 1-3 children faced acute health/communicative inequities in clinical settings, epidemiological investigations, work with healers, news coverage, health policy, and health communication...
