BACKGROUND: Follow-up data on patients with 46,XY partial gonadal dysgenesis (PGD) until adulthood are scarce, making information on prognosis difficult. OBJECTIVE: To analyse the long-term outcomes of patients with 46,XY PGD regarding testosterone production, germ cell tumour risk, genotype, and psychosexual adaptation. METHODS: A retrospective longitudinal study of 33 patients (20 assigned male and 13 patients assigned female at birth). Molecular diagnosis was performed by Sanger sequencing or by targeted massively parallel sequencing of 63 genes related to disorders of sex development (DSDs)...

Lockhart and Keil have written an interesting monograph focusing on the development of reasoning about medicine, a relatively underexplored area of research with potentially broad implications with respect to the design of more-effective medical interventions. In a set of 15 studies with well over 2,200 participants, they examine how children and adults combine aspects of biological and psychological reasoning to create working models of medicine. Lockhart and Keil explore developmental changes in reasoning about illness and its treatment using medicines in terms of dualism (e...

OBJECTIVES: Neurogenic cough is believed to result from a sensory neuropathy involving the internal branch of the superior laryngeal nerve (SLN). We present our outcomes for the treatment of neurogenic cough with localized blockade of the internal branch of the SLN. METHODS: A retrospective chart review of patients who underwent in-office percutaneous SLN block for treatment of neurogenic cough between 2015 and 2017 was conducted. Patient demographics, indications for injection, and response to treatment were recorded and analyzed...

BACKGROUND: The postnatal gonadotropin surge is sexually dimorphic: FSH levels predominate in girls and LH levels in boys. However, in preterm (PT) girls, both gonadotropin levels are higher than in PT boys. OBJECTIVE: To evaluate how gonadal maturation contributes to the sex differences in FSH and LH. DESIGN: Monthly follow-up of 58 full-term (FT, 29 boys) and 67 PT (33 boys) infants from one week (D7) to six months of age (M1-M6). Analyses were also done according to postmenstrual (PM) age in PT infants...

Anterior cruciate ligament (ACL) tears occur in isolation or in tandem with other intra-articular injuries such as meniscus tears. The impact of injury pattern on the molecular biology of the injured ACL is unknown. Here, we tested the hypothesis that the biological response of the ACL to injury varies based on the presence or absence of concomitant meniscus tear. We performed RNA-seq on 28 ACL tears remnants (12 isolated, 16 combined). In total, 16,654 transcripts were differentially-expressed between isolated and combined injury groups at false-discovery-rate of 0...

Infants who graduate from the neonatal intensive care unit, including those infants born preterm and/or with brain injury, are at increased risk of long-term neurodevelopmental impairments. The developmental allied health team, consisting of physical therapy, occupational therapy, and speech pathology, is crucial in early evaluation of gross motor, fine motor, feeding, and language development. Surveillance of neurodevelopment in the first year of life is essential to ensure early detection of specific developmental delays and impairments, and to ensure timely referral for early intervention...

Genotypes of 10 microsatellite loci of 420 humpback whales from the Southwestern Atlantic Ocean population were used to estimate for the first time its contemporary effective (Ne) and census (Nc) population sizes and to test the genetic effect of commercial whaling. The results are in agreement with our previous studies that found high genetic diversity for this breeding population. Using an approximate Bayesian computation approach, the scenario of constant Ne was significantly supported over scenarios with moderate to strong size changes during the commercial whaling period...

Resolving the temporal dynamics of cell signaling pathways is essential for regulating numerous downstream functions, from gene expression to cellular responses. Mapping these signaling pathways requires the exposure of cells to time-varying chemical signals; these are difficult to generate and control over a wide temporal range. Herein, we present an acoustofluidic chemical signal generator based on a sharp-edge-based micromixing strategy. The device, simply by modulating the driving signals of an acoustic transducer including the ON/OFF switching frequency, actuation time and duty cycle, is capable of generating both single-pulse and periodic chemical signals that are temporally controllable in terms of stimulation period, stimulation duration and duty cycle...

We aimed to investigate the different effects of low oxygen (5% O2 ) and atmospheric oxygen (20% O2 ) on in vitro fertilization for older poor ovarian responders (PORs). We selected 1080 older PORs who met two criteria: (i) advanced maternal age (≥40) and (ii) an abnormal ovarian reserve test. All the patients used the ultra-short term protocols with GnRH agonist and recombinant FSH for controlled ovarian hyperstimulation (COH). About 506 cycles were performed in the incubators with 5% O2 and 574 cycles were performed in the incubators with 20% O2 ...

The contact line dynamics of evaporating droplets deposited on a set of parallel micro-ribs is analyzed with the use of a recently developed entropic lattice Boltzmann model for two-phase flow. Upon deposition, part of the droplet penetrates into the space between ribs due to capillary action, while the remaining liquid of the droplet remains pinned on top of the micro-ribs. In a first stage, evaporation continues until the droplet undergoes a series of pinning-depinning events, showing alternatively constant contact radius and constant contact angle modes...

Habit reversal training (HRT) is a clinically effective treatment for body-focused repetitive disorders (BFRDs) such as trichotillomania, onychophagia, and dermatillomania. Despite many dermatology providers knowing the term HRT, very few understand what HRT is and how it actually works. In this article, we give a detailed explanation of HRT and walk the reader through a six-session HRT protocol. We will briefly discuss adjunct interventions for BFRDs, including pharmacological approaches. We aim to make dermatologists more comfortable in offering basic HRT within their clinics and to close the gap that currently exists between patients who are HRT candidates and those who receive HRT treatment...

Optic neuritis remains a common diagnosis with controversial management. Although typical optic neuritis is often associated with "good" recovery of visual acuity, patients are often left with persistent impairments of contrast sensitivity, color vision, and visual field. These permanent visual deficits correlate with structural injury to the anterior visual pathway and are closely linked to visual quality of life. High dose corticosteroids are commonly used for patients with acute optic neuritis...

ISSUE ADDRESSED: How much Australia spends on prevention, how this compares with other OECD countries and how do we know if Australia spends enough. METHODS: Document review and integrative literature review. RESULTS: Australia spends $89 per person on prevention: or 1.34% of all health spending and 0.13% of gross domestic product (GDP). In comparison to other OECD countries, Australia is distinctly 'mid-table', 16th (of 31 countries) in terms of per capita spending, 19th in terms of share of GDP, and 20th in terms of share of health spending...

PHAP1 (Putative HLA-DR-associated protein 1), also termed acidic leucine-rich nuclear phosphoprotein 32A (ANP32A), Phosphoprotein 32 (pp32) or protein phosphatase 2A inhibitor (I1PP2A), is a multifunctional protein aberrantly expressed in multiple types of human cancers. However, its expression pattern and clinical relevance in human glioma remain unknown. In this study, Western blotting and immunohistochemistry analysis demonstrated PHAP1 protein was highly expressed in glioma patients, especially in those with high-grade disease...

We examine the dynamic relationships between economic status and health measures using data from 8 waves of the Panel Study of Income Dynamics from 1999 to 2013. Health measures are self-rated health (SRH) and functional limitations; economic status measures are labor income (earnings), family income, and net wealth. We use 3 different types of models: (a) ordinary least squares regression, (b) first-difference, and (c) system-generalized method of moment (GMM). Using ordinary least squares regression and first difference models, we find that higher levels of economic status are associated with better SRH and functional status among both men and women, although declines in income and wealth are associated with a decline in health for men only...

In our search for novel histone deacetylases inhibitors, we have designed and synthesized a series of novel hydroxamic acids and N-hydroxybenzamides incorporating quinazoline heterocycles (4a-i, 6a-i). Bioevaluation showed that these quinazoline-based hydroxamic acids and N-hydroxybenzamides were potently cytotoxic against three human cancer cell lines (SW620, colon; PC-3, prostate; NCI-H23, lung). In term of cytotoxicity, several compounds, e.g. 4g, 4c, 4g-i, 6c, and 6h, displayed from 5- up to 10-fold higher potency than SAHA (suberoylanilidehydroxamic acid, vorinostat)...
