BACKGROUND: In the United States, hyperemesis gravidarum is the most common cause of hospitalization during the first half of pregnancy and is second only to preterm labor for hospitalizations in pregnancy overall. In approximately 0.3-3% of pregnancies, hyperemesis gravidarum is prevalent and this percentage varies on account of different diagnostic criteria and ethnic variation in study populations. Despite extensive research in this field, the mechanism of the disease is largely unknown...

Renée J St-Onge, Marie A Elliot
Non-coding regulatory RNAs fine-tune gene expression post-transcriptionally. In the streptomycetes, rpfA - encoding a muralytic enzyme required for establishing and exiting dormancy - is flanked by non-coding regulatory RNA elements both upstream (riboswitch) and downstream [antisense small RNA (sRNA)]. In Streptomyces coelicolor, the upstream riboswitch decreases rpfA transcript abundance in response to the second messenger cyclic di-AMP, itself involved in cell wall metabolism and dormancy. There is, however, no obvious expression platform associated with this riboswitch and consequently, its mechanism of action is entirely unknown...

Context: Delayed TSH elevation (dTSH) is defined as elevated TSH in the second neonatal screen (following normal TSH in the initial screen) in premature, low-birth-weight and sick newborns, mostly in the neonatal intensive care unit (NICU) setting. The pathogenesis of dTSH is elusive. Objective: To identify risk factors for dTSH development among newborns in the NICU. Design: setting and patients: A retrospective chart review of neonates with dTSH was conducted in eight university-affiliated NICUs...

Conjugation of small molecule payloads to specific cysteine residues on proteins via a disulfide bond represents an attractive strategy to generate redox-sensitive bioconjugates, which have value as potential diagnostic reagents or therapeutics. Advancement of such "direct-disulfide" bioconjugates to the clinic necessitates chemical methods to form disulfide connections efficiently, without byproducts. The disulfide connection must also be resistant to premature cleavage by thiols prior to arrival at the targeted tissue...

Obesity affects more than 35% of Americans, increasing the risk of more than 200 comorbid conditions, impaired quality of life and premature mortality. This review aimed to summarize literature published over the past 15 years regarding the prevalence and impact of obesity in people with haemophilia (PWH) and to discuss implementing general guidelines for weight management in the context of the haemophilia comprehensive care team. Although few studies have assessed the effects of obesity on haemophilia-specific outcomes, existing evidence indicates an important impact of weight status on lower extremity joint range of motion and functional disability, with potentially important effects on overall quality of life...

Childhood obesity is a public health problem, which is associated with a long-term increased risk of cardiovascular disease and premature mortality. Several gene variants have previously been identified that have provided novel insights into biological factors that contribute to the development of obesity. As obesity tracks through childhood into adulthood, identification of the genetic factors for obesity in early life is important. The objective of this study was to identify putative associations between genetic variants and obesity traits in children at 6 years of age...

The association of infantile spasms and periventricular leukomalacia and/or intraventricular hemorrhage is well documented. Data regarding early treatment-based and long-term outcomes are limited. A retrospective chart review identified children with infantile spasms born prematurely (<37 weeks) with diagnoses of periventricular leukomalacia and/or intraventricular hemorrhage. Thirteen children were included. Median gestational age was 30 weeks and age of onset of infantile spasms was 8 months. Nine children had intraventricular hemorrhage, 10 had periventricular leukomalacia, and 6 children had both...

Binary bat algorithm (BBA) is a binary version of the bat algorithm (BA). It has been proven that BBA is competitive compared to other binary heuristic algorithms. Since the update processes of velocity in the algorithm are consistent with BA, in some cases, this algorithm also faces the premature convergence problem. This paper proposes an improved binary bat algorithm (IBBA) to solve this problem. To evaluate the performance of IBBA, standard benchmark functions and zero-one knapsack problems have been employed...

Visual loss caused by retinopathy of prematurity (ROP) will be prevented if treatment-requiring ROP (TR-ROP) can be predicted. In this retrospective study including 418 infants with ≤32 weeks of gestational age (GA) and/or ≤1500 grams of birthweight, we attempted to identify useful predictors. We also examined the efficiency of significant predictors compared with existing predictive models, ROPScore and CHOP model. Multivariable logistic regression analyses supported the following factors were useful for predicting TR-ROP from all infants and infants with any ROP: GA (odds ratio [OR], 0...

BRCA1 associated ring domain protein 1(BARD1) is a tumor suppressor protein having a wide role in cellular processes like cell-cycle checkpoint, DNA damage repair and maintenance of genomic integrity. Germ-line mutation Gln 564 His discovered in linker region of BARD1 leads to loss of binding to Cleavage stimulating factor (CstF50), which in turn instigates the premature mRNA transcript formation and apoptosis. We have studied the dynamics of ARD domain present in the BARD1 wild-type and mutant protein in association with CstF50 using biophysical, biochemical and molecular dynamics simulations...

BACKGROUND: Prader-Willi syndrome (PWS) is a rare congenital disease that affects growth, sexual development, cognitive function and behavior. Individuals exhibit food preoccupation and hyperphagia, which may lead to obesity with premature morbidity and mortality. The aim of this work was to evaluate the risk of venous thromboembolisms (VTE), myocardial infarction, pulmonary hypertension, sleep apnea, depression, anxiety and all-cause mortality among persons with PWS as compared to an age- and sex-matched general population cohort...

Ionizing radiation (IR) is commonly used in cancer therapy and is a main source of DNA double-strand-breaks (DSBs), one of the most toxic forms of DNA damage. We have used Caenorhabditis elegans as an invertebrate model to identify novel factors required for repair of DNA damage inflicted by IR. We have performed an unbiased genetic screen, finding that smg-1 mutations confer strong hypersensitivity to IR. SMG-1 is a phosphoinositide-3 kinase (PI3K) kinase involved in mediating nonsense-mediated mRNA decay (NMD) of transcripts containing premature stop codons and related to the ATM and ATR kinases which are at the apex of DNA damage signalling pathways...

Salter-Harris type I (SH-I) fractures of the distal fibula are commonly encountered in pediatric orthopedics. We describe 2 unique cases of adolescents with completely displaced SH-I distal fibula fractures that were treated operatively. In the first case, a closed reduction attempt failed and the patient required open reduction and internal fixation of the distal fibula and syndesmosis. The syndesmotic ligaments were avulsed from the distal fibular metaphysis. In the second case, closed reduction of the distal fibula fracture was partially successful, but anatomic reduction could not be achieved without open reduction...

INTRODUCTION: Intussusception usually is associated with children, rarely with adults. CASE PRESENTATION: A 42-year-old pregnant woman (29 weeks' gestation) reported mild pain in the upper aspect of the abdomen after an intense physical effort. Ultrasound examination found a normally evolving pregnancy and a bowel obstacle, without bowel distention. Because it was not a surgical emergency at the time of evaluation, she was sent to the hospital's Obstetrics Department...

BACKGROUND: Most evidence on the association between malaria in pregnancy and adverse pregnancy outcomes focuses on falciparum malaria detected at birth. We assessed the association between the number and timing of falciparum and vivax malaria episodes during pregnancy on small-for-gestational-age (SGA) and preterm birth. METHODS: We analysed observational data collected from antenatal clinics on the Thailand-Myanmar border (1986-2015). We assessed the effects of the total number of malaria episodes in pregnancy on SGA and the effects of malaria in pregnancy on SGA, very preterm birth, and late preterm birth, by the gestational age at malaria detection and treatment using logistic regression models with time-dependent malaria variables (monthly intervals)...

Background: Permanent supportive housing (PSH) has been recognized as an effective intervention and the national policy for addressing chronic homelessness in the United States. Due to an aging cohort of homeless adults and prioritizing those who are most vulnerable for housing, the health status of those entering PSH is likely worse than those previously reported in the literature. Methods: This report examined the self-reported health and health conditions of a sample of 421 homeless adults entering PSH between 2014 and 2016...

Aims: The arrhythmic risk stratification of arrhythmogenic right ventricular cardiomyopathy (ARVC) remains controversial. We evaluated the long-term distribution of life-threatening arrhythmic events assessing the impact of periodical risk reassessment. Methods and results: Ninety-eight ARVC patients with no previous major ventricular arrhythmias were retrospectively analysed. Patients were assessed at baseline, at 22 [inter-quartile range (IQR) 16-26], 49 (IQR 41-55) and 97 months (IQR 90-108)...
