Hypertension affects nearly one of three women and contributes to cardiovascular disease, the leading cause of death in the United States. Breastfeeding leads to metabolic changes that could reduce risks of hypertension. Hypertension disproportionately affects black women, but rates of breastfeeding lag behind the general population. In the Black Women's Health Study (N = 59,001), we conducted a nested case control analysis using unconditional logistic regression to estimate the association between breastfeeding and incident hypertension at ages 40-65 using data collected from 1995 to 2011...

PURPOSE: To evaluate if incisional prophylactic negative pressure wound therapy (pNPWT) reduces wound infections and other wound complications in high-risk patients undergoing major complex ventral abdominal wall repair. METHODS: Retrospective before-after comparison nested in a consecutive series of patients undergoing elective major complex abdominal wall repair. Starting January 2014, pNPWT was applied on the closed incisional wound for a minimum of 5 days. To minimize selection bias, we compared two periods of 14 months before and after January 2014...

PURPOSE: Periodontal disease, a major cause of tooth loss in adults, may have systemic effects and has been associated with higher risk of several cancer types. However, the associations of periodontal disease or tooth loss with liver cancer have only been examined prospectively in two studies, neither of which had sufficient statistical power. In addition, no studies assessed the potential confounding by viral hepatitis or Helicobacter pylori infection status. METHODS: In this study, we examined the association between tooth loss and primary liver cancer incidence in a prospective cohort of Finnish male smokers (n = 29,096)...

The Rhus gall aphids are sometimes referred to as subtribe Melaphidina (Aphididae: Eriosomatinae: Fordini) and comprise a unique group that forms galls on the primary host plants, Rhus. We examined the evolutionary relationships within the Melaphidina aphids using sequences of the complete mitochondrial genome and with samples of 11 of the 12 recognized species representing all six genera. Bayesian, maximum likelihood and parsimony analyses of the mitochondrial genome data support five well-supported clades within Melaphidina: (1) Nurudea (except N...

Trialeurodes vaporariorum (Westwood, 1856) (Greenhouse whitefly) is an agricultural pest of global importance. It is associated with damage to plants during feeding and subsequent virus transmission. Yet, global phylogenetic relationships, population structure, and estimation of the rates of gene flow within this whitefly species remain largely unexplored. In this study, we obtained and filtered 227 GenBank records of mitochondrial cytochrome c oxidase I (mtCOI) sequences of T. vaporariorum, across various global locations to obtain a final set of 217 GenBank records...

Background: Low and deficient levels of vitamin A are common in low and middle income countries where tuberculosis (TB) burden is high. We assessed the impact of baseline levels of vitamins A and carotenoids on TB disease risk. Methods: We conducted a case-control study nested within a longitudinal cohort of household contacts of pulmonary TB cases in Lima, Peru. We defined cases as HIV-negative household contacts with blood samples who developed TB disease at least 15 days after enrollment of index patient...

BACKGROUND: Respiratory syncytial virus (RSV) is an important cause of lower respiratory tract disease in early life and a target for vaccine prevention. Data on the age-prevalence of RSV specific antibodies will inform on optimizing vaccine delivery. METHODS: Archived plasma samples were randomly selected within age strata from 960 children less than 145 months of age admitted to Kilifi County Hospital pediatric wards between 2007 and 2010. Samples were tested for antibodies to RSV using crude virus IgG ELISA...

BACKGROUND: HPV infections are ubiquitous and particularly common among sexually active young women. However, there are regional and national variations in age-specific HPV prevalence, which have implications for cervical cancer control. Data on age-specific HPV prevalences for Ghana and most sub-Saharan countries are scanty. Therefore, this study primarily sought to determine the age-specific HPV prevalence among women in a Ghanaian community and to determine whether these prevalences determined with health-personnel and self-collected specimens were comparable...

Dermestidae and Tenebrionidae are well known inhabitants of bird's nests and poultry farms, under favourable conditions they can be very abundant under favourable conditions. At times, their larvae shift from a scavenging behaviour to a parasitic/predatory one, entering nestling's plumage and feeding on skin and feathers, and nally provoking skin damages and blood losses. These episodes mainly involve species of the genus Dermestes, but the tenebrionid Alphitobius diaperinus h also been reported to be responsible of similar cases...

INTRODUCTION: Children increasingly are being seen in the emergency department for a concussion, or mild traumatic brain injury (mTBI). A key aim of the ED visit is to provide discharge advice that can help parents to identify an evolving neurosurgical crisis, facilitate recovery, and prevent reinjury. The present study examined parents' knowledge of symptoms and recall of discharge instructions after their adolescent's mTBI and the effect of supplementing written discharge instructions with verbal instruction and reinforcement...

INTRODUCTION: Clostridium difficile infection is the leading cause of nosocomial infectious diarrhea. The increasing incidence added to a lower rate of response to the initial treatment and higher rates of relapse has generated a higher burden of the disease. OBJECTIVE: To determine the clinical characteristics of hospitalized patients with C. difficile infection. MATERIALS AND METHODS: We made a nested case-cohort study. We reviewed medical records of the patients with nosocomial diarrhea for whom an assay for toxin A-B of C...

We introduce multilevel multivariate meta-analysis methodology designed to account for the complexity of contemporary psychological research data. Our methodology directly models the observations from a set of studies in a manner that accounts for the variation and covariation induced by the facts that observations differ in their dependent measures and moderators and are nested within, for example, papers, studies, groups of subjects, and study conditions. Our methodology is motivated by data from papers and studies of the choice overload hypothesis...

GlyTouCan version 1.0 was released in 2015 as the international glycan structure repository, and a new sequence format called WURCS (Web3 Unique Representation of Carbohydrate Structures) was proposed during the early stages of the GlyTouCan project. GlyTouCan uses WURCS as its base representation for glycans because existing formats were insufficient in their flexibility to represent any and all glycans universally. Therefore, in order to obtain WURCS strings for existing or new glycan structures, conversion tools or glycan structure editors that can export WURCS became necessary...

Papillary and pseudopapillary features are histopathologic findings typically associated with carcinomas (thyroid, pancreas, breast, prostate, bladder, kidney, or ovary) or mesothelioma. Melanoma is typically composed of nested and variably pigmented atypical cells. Here, we report a case of in-transit metastasis of melanoma presenting with prominent papillary features, and we discuss the differential diagnoses of neoplasms with papillary features. This case report suggests that the spectrum of neoplasms with papillary features should be expanded to include melanoma, a pattern that, to the best of our knowledge, is uncommon...

Ornithonyssus sylviarum is a blood-feeding ectoparasite of birds and the most serious pest in poultry farms in North America. Although the mites are typically adapted to temperate climates, information on this mite in Europe is sparse, and Dermanyssus gallinae is considered to be the only mite impacting the poultry industry. The present study reports the occurrence of O. sylviarum in pet birds in Portugal. Mites were collected directly from birds and with traps placed in cages and nests at 20 different sampling places belonging to 6 municipalities in the district of Setúbal...

Primary neuroendocrine tumors (NETs) of the mediastinum are very rare. Prognosis is usually poor despite treatment options. We present the case of a primary atypical carcinoid tumor of the mediastinum successfully treated by multimodal approach. A 50-year-old man presented for asthenia, dyspnea, and substernal sense of weight for two weeks. A chest-CT scan revealed a tumor mass of 107×55×95 mm(3) localized in the anterosuperior mediastinum compressing both brachiocephalic veins, the superior vena cava, the pericardium, and lungs...
