PurposePanel-based genetic testing has identified increasing numbers of patients with pancreatic ductal adenocarcinoma (PDAC) who carry germ-line mutations. However, small sample sizes or number of genes evaluated limit prevalence estimates of these mutations. We estimated prevalence of mutations in PDAC patients with positive family history.MethodsWe sequenced 25 cancer susceptibility genes in lymphocyte DNA from 302 PDAC patients in the Mayo Clinic Biospecimen Resource for Pancreatic Research Registry. Kindreds containing at least two first-degree relatives with PDAC met criteria for familial pancreatic cancer (FPC), while the remaining were familial, but not FPC...

Europe has played a major role in dog evolution, harbouring the oldest uncontested Palaeolithic remains and having been the centre of modern dog breed creation. Here we sequence the genomes of an Early and End Neolithic dog from Germany, including a sample associated with an early European farming community. Both dogs demonstrate continuity with each other and predominantly share ancestry with modern European dogs, contradicting a previously suggested Late Neolithic population replacement. We find no genetic evidence to support the recent hypothesis proposing dual origins of dog domestication...

PURPOSE: To provide evidence-based, resource-stratified global recommendations to clinicians and policymakers on the management and palliative care of women diagnosed with invasive cervical cancer. METHODS: ASCO convened a multidisciplinary, multinational panel of cancer control, medical and radiation oncology, health economic, obstetric and gynecologic, and palliative care experts to produce recommendations reflecting resource-tiered settings. A systematic review of literature from 1966 to 2015 failed to yield sufficiently strong quality evidence to support basic- and limited-resource setting recommendations; a formal consensus-based process was used to develop recommendations...

Emergence of epidemic clones and antibiotic resistance development compromises the management of Pseudomonas aeruginosa cystic fibrosis (CF) chronic respiratory infections. Whole genome sequencing (WGS) was used to decipher the phylogeny, interpatient dissemination, WGS mutator genotypes (mutome) and resistome of a widespread clone (CC274), in isolates from two highly-distant countries, Australia and Spain, covering an 18-year period. The coexistence of two divergent CC274 clonal lineages was revealed, but without evident geographical barrier; phylogenetic reconstructions and mutational resistome demonstrated the interpatient transmission of mutators...

OBJECTIVES: Emerging evidence suggests that extent of lymphovascular space invasion (LVSI) predicts for risk of lymph node metastasis in endometrioid uterine cancers. However, this correlation remains unknown in the setting of uterine serous carcinoma (USC). We sought to examine the association between extent of LVSI and other histopathologic characteristics with risk of nodal metastasis for women with USC. MATERIALS/METHODS: Pathological data from all cases of uterine serous carcinoma between July 1998 to July 2015 at our institution were reviewed...

BACKGROUND: The desire to make meaning out of images, metaphor, and other representations indicates higher-order cognitive skills that can be difficult to teach, especially in the complex and unfamiliar environments like those encountered in many global health experiences. Because reflecting on art can help develop medical students' imaginative and interpretive skills, we used visual thinking strategies (VTS) during an immersive 4-week global health elective for medical students to help them construct new understanding of the social determinants of health in a low-resource setting...

Many people report that reading first-person narratives of the experience of illness can be morally instructive or educative. But although they are ubiquitous and typically sincere, the precise nature of such educative experiences is puzzling, for those narratives typically lack the features that modern philosophers regard as constitutive of moral reason. I argue that such puzzlement should disappear, and the morally educative power of illness narratives explained, if one distinguishes two different styles of moral reasoning: an inferentialist style that generates the puzzlement and an alternative exemplarist style that offers a compelling explanation of the morally educative power of pathographic literature...

INTRODUCTION: Sarcoidosis is a systemic inflammatory disease characterized by non-necrotizing granulomas in involved organs, most commonly the lung. Description of patient characteristics in the Western United States is limited. Furthermore, blood-based measures that relate to clinical sarcoidosis phenotypes are lacking. We present an analysis of a prospective, longitudinal sarcoidosis cohort at a Northern Californian academic medical center. METHODS: We enrolled 126 sarcoidosis subjects and 64 healthy controls and recorded baseline demographic and clinical characteristics...

The paediatric intensive care unit (PICU) provides care to critically ill neonates, infants and children. These patients are vulnerable and susceptible to the environment surrounding them, yet there is little information available on indoor air quality and factors affecting it within a PICU. To address this gap in knowledge we conducted continuous indoor and outdoor airborne particle concentration measurements over a two-week period at the Royal Children's Hospital PICU in Brisbane, Australia, and we also collected 82 bioaerosol samples to test for the presence of bacterial and viral pathogens...

BACKGROUND: Massive blood loss during posterior spinal fusion for adolescent idiopathic scoliosis remains a significant risk for patients. There is no consensus on the benefit of acute normovolemic hemodilution (ANH) or intraoperative cell salvage (ICS) in scoliosis surgery. METHODS: Patients were randomized to one of two groups. Group A received ANH and ICS during operation, while group B received only ICS. Patients' age, sex, height, weight, body blood volume, number of fusion level, Cobb angle, number of screws, duration of surgery, and skin incision length were recorded...

A bidirectional communication between the immune and endocrine systems exists and facilitates optimum responses in the host during infections. This is in part achieved through changes in secretion patterns of hypothalamic hormones induced by inflammatory cytokines. The aim of this study was to elucidate the immune-endocrine alterations during tuberculosis (TB) treatment in patients with cured and failed TB treatment outcomes. Blood samples were collected from 27 cured and 10 failed patients and hormone as well as cytokine concentrations quantified at baseline, week 4, and month 6 of TB treatment...

More than 300 red blood cell (RBC) antigens belonging to 36 blood group systems have been officially reported in humans by the International Society of Blood Transfusion (ISBT). Phenotypic variability is directly linked to the expression of the 41 blood group genes. The Rh blood group system, which is composed of 54 antigens, is the most complex and polymorphic system. Many rare genetic variants within the RH (RHD and RHCE) genes, involving various mutational mechanisms (single-nucleotide substitutions, short insertions/deletions, rearrangements, large deletions), have been reported in the literature and reference databases...

The greatest risk factor for Alzheimer's disease (AD) is advanced age, but the reason for this association remains unclear. Amyloid-beta (Aβ) is produced from amyloid precursor protein (APP) primarily after APP is internalised by clathrin-mediated or clathrin-independent endocytosis. Changes in endocytosis in AD have been identified. We hypothesised that endocytic protein expression is altered during ageing, thus influencing the likelihood of developing AD by increasing Aβ production. We explored how levels of endocytic proteins, APP, its metabolites, secretase enzymes and tau varied with age in cortical brain samples from men of three age ranges (young (20-30), middle-aged (45-55) and old (70-90)) with no symptoms of dementia...
