Prevalent coinfection and associated factors for Hepatitis B, Hepatitis C, and Human Immunodeficiency Virus in patients submitted to renal replacement therapy: A cross-sectional study of 21 dialysis units in the State of Mexico.

Background: Chronic kidney disease (CKD) predispose to viral coinfections in patients submitted to renal replacement therapy (RRT); nevertheless, few reports have been performed to elucidate the current epidemiology within this population in Mexico.

Aim: To estimate the prevalence of HBV, HCV, and HIV coinfection and to explore factors associated with prevalent coinfection in patients living with renal failure undergoing to RRT.

Methods: A multicenter cross-sectional recruitment across 21 units at the Mexican Institute of Social Security (IMSS) at the State of Mexico was performed during 2019.

Integration of mouse ovary morphogenesis with developmental dynamics of the oviduct, ovarian ligaments, and rete ovarii.

Morphogenetic events during the development of the fetal ovary are crucial to the establishment of female fertility. However, the effects of structural rearrangements of the ovary and surrounding reproductive tissues on ovary morphogenesis remain largely uncharacterized. Using tissue clearing and lightsheet microscopy, we found that ovary folding correlated with regionalization into cortex and medulla.

Mammalian uterine morphogenesis and variations.

In eutherian and marsupial mammals, the site of embryo implantation and gestation is the uterus. Uterine morphologies vary between mammalian species. For example, laboratory mice have a bipartite uterus with two uterine horns and a single cervix, whereas humans have a simplex uterus with a single chamber and single cervix.

High throughput image labeling on chest computed tomography by deep learning.

When mining image data from PACs or clinical trials or processing large volumes of data without curation, the relevant scans must be identified among irrelevant or redundant data. Only images acquired with appropriate technical factors, patient positioning, and physiological conditions may be applicable to a particular image processing or machine learning task. Automatic labeling is important to make big data mining practical by replacing conventional manual review of every single-image series.

AMH and AMHR2 mutations: A spectrum of reproductive phenotypes across vertebrate species.

Anti-Müllerian hormone (AMH) is a member of the Transforming Growth Factor-β family of secreted signaling proteins. AMH is expressed in Sertoli cells of the fetal and adult testes and granulosa cells of the postnatal ovary. AMH is required for the regression of the Müllerian ducts in mammalian fetuses during male differentiation.

Fine-mapping scan of bipolar disorder susceptibility loci in Latino pedigrees.

We previously identified bipolar disorder (BD) susceptibility loci on 8q24, 14q32, and 2q12-14 in a genome-wide nonparametric linkage screen in a Latino cohort. We now perform a fine mapping analysis using a dense map of additional SNPs to identify BD susceptibility genes within these regions. One thousand nine hundred and thirty-eight individuals with Latino ancestry (880 individuals with BD Type I or Schizoaffective, Bipolar Type) from 416 Latino pedigrees from the United States, Mexico, Costa Rica, and Guatemala were genotyped with 3,074 SNPs to provide dense coverage of the 8q24 (11.

The Relationship of Assisted Reproductive Technology on Perinatal Outcomes in Triplet Gestations.

Objective: To assess whether assisted reproductive technology (ART) is associated with increased risk of adverse perinatal outcomes in triplet gestations compared with spontaneous conception.

Study Design: Secondary analysis of a multicenter randomized trial for the prevention of preterm birth in multiple gestations. Triplets delivered at ≥ 24 weeks were studied.

The impact of time of delivery on gestations complicated by preterm premature rupture of membranes: daytime versus nighttime.

Perinatal death, in particular intrapartum stillbirth and short-term neonatal death, as well as neonatal short-term and long-term morbidity have been associated with the time of day that the birth occurs. Indeed, evening and nighttime deliveries were associated with an increased risk of an adverse perinatal outcome when compared to similar daytime deliveries. Impact of shift change, as well as time of day delivery have been extensively studied in the context of maternal and neonatal complications of cesarean delivery, however, no studies were previously performed on timing of delivery and its effect on the outcome of pregnancies complicated by preterm premature rupture of membranes.

A genome-wide quantitative trait locus (QTL) linkage scan of NEO personality factors in Latino families segregating bipolar disorder.

Personality traits have been suggested as potential endophenotypes for Bipolar Disorder (BP), as they can be quantitatively measured and show correlations with BP. The present study utilized data from 2,745 individuals from 686 extended pedigrees originally ascertained for having multiplex cases of BP (963 cases of BPI or schizoaffective BP). Subjects were assessed with the NEO Personality Inventory, Revised (NEO PI-R) and genotyped using the Illumina HumanLinkage-24 Bead Chip, with an average genetic coverage of 0.

Replication of genome-wide association study (GWAS) susceptibility loci in a Latino bipolar disorder cohort.

Objectives: Recent genome-wide association studies (GWASs) have identified numerous putative genetic polymorphisms associated with bipolar disorder (BD) and/or schizophrenia (SC). We hypothesized that a portion of these polymorphisms would also be associated with BD in the Latino American population. To identify such regions, we tested previously identified genetic variants associated with BD and/or SC and ancestral haploblocks containing these single nucleotide polymorphisms (SNPs) in a sample of Latino subjects with BD.

Uterus-targeted liposomes for preterm labor management: studies in pregnant mice.

Preterm labor caused by uterine contractions is a major contributor to neonatal morbidity and mortality. Treatment intended to reduce uterine contractions include tocolytic agents, such as indomethacin. Unfortunately, clinically used tocolytics are frequently inefficient and cross the placenta causing fetal side effects.

The effect of combined inositol supplementation on maternal metabolic profile in pregnancies complicated by metabolic syndrome and obesity.

Background: Myoinositol and D-chiroinositol improve insulin resistance in women with obesity and gestational diabetes and in postmenopausal women with metabolic syndrome. We previously reported that offspring born to hypertensive dams lacking endothelial nitric oxide synthase and fed a high-fat diet develop metabolic-like syndrome phenotype.

Objective: The objective of the study was to investigate the effect of a mixture of myoinositol/D-chiroinositol supplementation during pregnancy on the maternal metabolic profile in pregnancies complicated by the metabolic-like syndrome and obesity using a pregnant mouse model.

Safety of anticonvulsant agents in pregnancy.

Introduction: Seizures in pregnancy are particularly challenging, as their management requires careful consideration of not only the etiology of the seizure, but also the physiologic changes of pregnancy as well as potential adverse effects on the developing embryo or fetus. Newer antiepileptic drugs (AEDs) have increasingly shown promising results of lower rate of teratogenesis, as well as better seizure control during pregnancy.

Areas Covered: We performed a review of the scientific literature of seizures in pregnancy including status epilepticus as well as eclampsia, with a focus on safety of currently used AEDs.

Identification of circadian gene variants in bipolar disorder in Latino populations.

Background: Variations in circadian genes can impact biological rhythms. Given the rhythm disturbances that characterize bipolar disorder (BD), genes encoding components of molecular clocks are good candidate genes for the illness.

Methods: A family based association analysis of circadian gene single nucleotide polymorphisms (SNPs) and BD was conducted in Latino pedigrees.

Crossed-brain representation of verbal and nonverbal functions.

A 74-year-old, left-handed man presented with a rapidly evolving loss of strength in his right leg associated with difficulty in walking. MR images disclosed an extensive left hemisphere tumor. A neuropsychological examination revealed that language was broadly normal but that the patient presented with severe nonlinguistic abnormalities, including hemineglect (both somatic and spatial), constructional defects, and general spatial disturbances; symptoms were usually associated with right hemisphere pathologies.

Genome-wide methylome analyses reveal novel epigenetic regulation patterns in schizophrenia and bipolar disorder.

Schizophrenia (SZ) and bipolar disorder (BP) are complex genetic disorders. Their appearance is also likely informed by as yet only partially described epigenetic contributions. Using a sequencing-based method for genome-wide analysis, we quantitatively compared the blood DNA methylation landscapes in SZ and BP subjects to control, both in an understudied population, Hispanics along the US-Mexico border.

Clinical predictors of disease severity during the 2009-2010 A(HIN1) influenza virus pandemic in a paediatric population.

A novel influenza virus emerged in the United States in spring 2009, rapidly becoming a global pandemic. Children were disproportionally affected by the novel influenza A(H1N1) pandemic virus [A(H1N1)pdm]. This retrospective electronic medical record review study aimed to identify clinical predictors of disease severity of influenza A(HIN1)pdm infection in paediatric patients.

Development of chagas cardiac manifestations among Texas blood donors.

Chagas disease, infection with the parasite Trypanosoma cruzi, has recently been identified as an important emerging parasitic disease in the United States. To describe the cardiac abnormalities in T. cruzi-positive blood donors in southeastern Texas, a pilot study of donors who had screened positive from 2007 to 2012 was performed.

A genome-wide linkage scan of bipolar disorder in Latino families identifies susceptibility loci at 8q24 and 14q32.

A genome-wide nonparametric linkage screen was performed to localize Bipolar Disorder (BP) susceptibility loci in a sample of 3757 individuals of Latino ancestry. The sample included 963 individuals with BP phenotype (704 relative pairs) from 686 families recruited from the US, Mexico, Costa Rica, and Guatemala. Non-parametric analyses were performed over a 5 cM grid with an average genetic coverage of 0.

Suggestive evidence for association between L-type voltage-gated calcium channel (CACNA1C) gene haplotypes and bipolar disorder in Latinos: a family-based association study.

Objectives:   Through recent genome-wide association studies (GWASs), several groups have reported significant association between variants in the calcium channel, voltage-dependent, L-type, alpha 1C subunit (CACNA1C) and bipolar disorder (BP) in European and European-American cohorts. We performed a family-based association study to determine whether CACNA1C is associated with BP in the Latino population.

Methods:   This study included 913 individuals from 215 Latino pedigrees recruited from the USA, Mexico, Guatemala, and Costa Rica.

Genetic structure of personality factors and bipolar disorder in families segregating bipolar disorder.
