OBJECTIVES: Heavier birth weight predicts taller adult height, but it remains unknown the extent to which this additional height increment results from a faster average growth rate versus an extension of the growth period. Aiming to distinguish these effects, this study examined associations between birth weight (BW), age at menarche (an established proxy for growth duration), and near-adult height in a cohort of US young women born in the 1990s. METHODS: Multiple regression evaluated age-adjusted height as an outcome of BW, age at menarche, indicators of family socioeconomic status, and other potential confounders in a sample of US teens who participated in the National Health and Nutrition Examination Survey between 2007 and 2012 (N = 342)...

Motivated by an HIV example, we consider how to compare and combine treatment selection markers, which are essential to the notion of precision medicine. The current literature on precision medicine is focused on evaluating and optimizing treatment regimes, which can be obtained by dichotomizing treatment selection markers. In practice, treatment decisions are based not only on efficacy but also on safety, cost and individual preference, making it difficult to choose a single cutoff value for all patients in all settings...

It is well established that the neurodegenerative process of Alzheimer's disease (AD) begins many years before symptom onset. This preclinical phase provides a crucial time-window for therapeutic intervention, though this requires biomarkers that could evaluate the efficacy of future disease-modification treatments in asymptomatic individuals. The last decade has witnessed a proliferation of studies characterizing the temporal sequence of the earliest functional and structural brain imaging changes in AD. These efforts have focused on studying individuals who are highly vulnerable to develop AD, such as those with familial genetic mutations, susceptibility genes (i...

OBJECTIVE: Finite element analysis (FEA) has been suggested to be superior to maximal diameter measurements in predicting rupture of abdominal aortic aneurysms (AAAs). Our objective was to investigate to what extent previously described rupture risk factors were associated with FEA-estimated rupture risk. METHODS: One hundred forty-six patients with an asymptomatic AAA of a 40- to 60-mm diameter were retrospectively identified and consecutively included. The patients' computed tomography angiograms were analyzed by FEA without (neutral) and with (specific) input of patient-specific mean arterial pressure (MAP), gender, family history, and age...

When activated through toll-like receptors (TLRs), macrophages generate interleukin-33 (IL-33), an IL-1 family member that induces innate immune responses through ST2 signaling. Lipopolysaccharide (LPS), a TLR4 ligand, induces macrophages to generate prostaglandin E2 (PGE2) through inducible cyclooxygenase (COX)-2 and microsomal PGE2 synthase-1 (mPGES-1) (1). We demonstrate that IL-33 production by bone marrow derived murine macrophages (bmMFs) requires the generation of endogenous PGE2 and the intrinsic expression of EP2 receptors to amplify NF-κB-dependent LPS-induced IL-33 expression via Exchange Protein Activated by cAMP (EPAC)...

Chitosan is a family of glucosamine and N-acetyl glucosamine polysaccharides with poorly understood immune modulating properties. Here, functional U937 macrophage responses were analyzed in response to a novel library of twenty chitosans with controlled degree of deacetylation (DDA, 60-98%), molecular weight (1 to >100 kDa), and acetylation pattern (block vs. random). Specific chitosan preparations (10 or 190 kDa 80% block DDA and 3, 5, or 10 kDa 98% DDA) either induced macrophages to release CXCL10 and IL-1ra at 5-50 μg/mL, or activated the inflammasome to release IL-1β and PGE2 at 50-150 μg/mL...

 To test whether families' participation in an evidence-based parenting program can improve health-related outcomes reported by fathers of 2- to 10-year-old children with asthma and/or eczema.  A 2 (Triple P-Positive Parenting Program vs. care as usual) by 3 (baseline, postintervention, 6-month follow-up) design was used, with random group assignment. Of 107 families, 51.4% ( N  = 55) had a father participate alongside the child's mother, who was the primary intervention target. Fathers completed questionnaires assessing illness-related child behavior problems; self-efficacy with illness management and illness-related child behavior problems; and health-related quality of life...

Adult PD of bone is the second commonest metabolic bone condition after osteoporosis. The condition is characterized by increased bone cell activity, with bone-resorbing osteoclasts often larger and containing more nuclei than normal, and osteoblasts producing increased amounts of disorganized bone. This leads to expanded bone of poor quality possessing both sclerotic and lytic areas. PD of bone has a strong genetic element, with a family history being noted in 10-20% of cases. A number of genetic defects have been found to be associated with the condition...

Three species of Opisthomonorcheides Parukhin, 1966 are reported for the first time from Indonesian waters: O. pampi (Wang, 1982) Liu, Peng, Gao, Fu, Wu, Lu, Gao & Xiao, 2010 and O. ovacutus (Mamaev, 1970) Machida, 2011 from Parastromateus niger (Bloch), and O. decapteri Parukhin, 1966 from Atule mate (Cuvier). Both O. pampi and O. ovacutus can now be considered widespread in the Indo-Pacific region, with earlier records of these species being from Fujian Province, China and Penang, Malaysia, respectively. We redescribe O...

Erik Erikson's theoretical writings on identity have provided a rich foundation upon which decades of research on identity development have been built. However, literature is lacking regarding adolescents who are aware that they lack knowledge about the self (i.e., values, likes, and dislikes) to the extent that they are stuck and directionless, and therefore unable to engage in the process of identity formation, what we refer to as a state of "lostness." Furthermore, while it has been established that supportive relationships facilitate identity development, less is known about whether various domains of social connectedness may diminish "lostness" over time, and if so, what may be the specific processes or conditions within each connectedness domain that supports this aspect of identity development...

BACKGROUND: Evidence to guide policymakers in developing affordable and equitable cancer control plans are scarce in low- and middle-income countries (LMIC). METHODS: The 2012-2014 ASEAN Costs in Oncology Study prospectively followed-up 9513 newly diagnosed cancer patients from eight LMIC in Southeast Asia for 12 months. Overall and country-specific incidence of financial catastrophe (out-of-pocket health costs ≥ 30% of annual household income), economic hardship (inability to make necessary household payments), poverty (living below national poverty line), and all-cause mortality were determined...

BACKGROUND: Transthyretin (TTR) amyloidosis is a hereditary disease with a complex genotype-phenotype correlation. We conducted a literature survey to define the clinical landscape of TTR amyloidosis across populations worldwide. Then, we investigated whether the genetically determined TTR expression differs among human populations, contributing to the differences observed in patients. Polygenic scores for genetically determined TTR expression in 14 clinically relevant tissues were constructed using data from the GTEx (Genotype-Tissue Expression) project and tested in the samples from the 1,000 Genomes Project...

BACKGROUND: India is a patchwork of tribal and non-tribal populations that speak many different languages from various language families. Indo-European, spoken across northern and central India, and also in Pakistan and Bangladesh, has been frequently connected to the so-called "Indo-Aryan invasions" from Central Asia ~3.5 ka and the establishment of the caste system, but the extent of immigration at this time remains extremely controversial. South India, on the other hand, is dominated by Dravidian languages...

The 'continuum of care' is proposed as a key framework for the delivery of maternal, neonatal and child health services. This study examined the extent of dropout as well as factors associated with retention across the MNCH continuum from antenatal care (ANC), through skilled birth attendance (SBA), to postnatal care (PNC).We analyzed data from 1931 women who delivered in the preceding 2-14 months, from a two-stage cluster sampling household survey in four districts of Tanzania's Morogoro region. The survey was conducted in 2011 as a part of a baseline for an independent evaluation of a maternal health program...

INTRODUCTION AND AIMS: Fetal alcohol spectrum disorder (FASD) is a significant public health concern, and growing recognition in Australia led to the establishment of a specialist service for young children. The aim of the current study was to report on the diagnostic profile of a group of children who attended the service, to document the extent to which there were comorbid diagnoses and to provide information on the neurocognitive functioning of the children. DESIGN AND METHODS: This study was a retrospective chart review conducted by the diagnostic service...

Importance: Ophthalmic screening to check for diabetic retinopathy (DR) is important to prevent vision loss in persons with diabetes. The American Academy of Ophthalmology recommends that ophthalmic screening for DR occur beginning at 5 years after initial diabetes diagnosis for youths with type 1 diabetes; the American Diabetes Association recommends screening of youths with type 2 diabetes at the time of initial diagnosis. To our knowledge, it is unknown to what extent youths with diabetes obtain eye examinations in accordance with these guidelines...

BACKGROUND: SPATULA (SPT) and ALCATRAZ (ALC) are recent paralogs that belong to the large bHLH transcription factor family. Orthologs of these genes have been found in all core eudicots, whereas pre-duplication genes, named paleoSPATULA/ALCATRAZ, have been found in basal eudicots, monocots, basal angiosperms and gymnosperms. Nevertheless, functional studies have only been performed in Arabidopsis thaliana, where SPT and ALC are partially redundant in carpel and valve margin development and ALC has a unique role in the dehiscence zone...

Cell migration and cell-cell communication involves the protrusion of actin-rich cell surface projections such as lamellipodia and filopodia. Lamellipodia are networks of actin filaments generated and turned over by filament branching through Arp2/3 complex. Inhibition of branching is commonly agreed to eliminate formation and maintenance of lamellipodial actin networks, but the regulation of nucleation or elongation of Arp2/3-independent filament populations within the network e.g. by formins or Ena/VASP family members and its impact on the effectivity of protrusion have remained unclear...

Whole-exome/whole-genome sequencing (WES/WGS) has the potential to enhance genetic diagnosis of rare disease, and is increasingly becoming part of routine clinical care in mainstream medicine. Effective translation will require ongoing efforts in a number of areas including: selection of appropriate patients, provision of effective consent, pre- and post-test genetic counselling, improving variant interpretation algorithms and practices, and management of secondary findings including those found incidentally and those actively sought...

In the limbic brain, mineralocorticoid receptors (MRs) and glucocorticoid receptors (GRs) both function as receptors for the naturally occurring glucocorticoids (corticosterone/cortisol), but mediate distinct effects on cellular physiology via transcriptional mechanisms. The transcriptional basis for specificity of these MR- versus GR-mediated effects is unknown. To address this conundrum we have identified the extent of MR/GR DNA binding selectivity in the rat hippocampus using chromatin immunoprecipitation followed by sequencing (ChIP-seq)...
