Ovarian masses with papillary projections diagnosed and removed during pregnancy : ultrasound features and histological diagnosis

Objective: To elucidate the ultrasound features that can discriminate between benign and malignant ovarian cysts with papillary projections but no other solid component in pregnant women. Methods: Thirty-four women with an ultrasound diagnosis of an ovarian cyst with papillary projections but no other solid component that had been removed surgically during pregnancy were identified from the databa

An efficient sampling strategy for selection of biobank samples using risk scores

Aim: The aim of this study was to suggest a new sample-selection strategy based on risk scores in case-control studies with biobank data. Methods: An ongoing Swedish case-control study on fetal exposure to endocrine disruptors and overweight in early childhood was used as the empirical example. Cases were defined as children with a body mass index (BMI) ≥18 kg/m2 (n=545) at four years of age, and

Three-dimensional structures and functional studies of two GH43 arabinofuranosidases from Weissella sp. strain 142 and Lactobacillus brevis

Arabinofuranosidases degrade arabinose-containing oligo and polysaccharides, releasing l-arabinose, which is a potentially useful sugar, shown to reduce glycemic response under certain conditions. Arabinofuranosidases (Arafs) are frequently found in GH43, one of the most common GH-families encoded in genomes in gut microbiota, and hence it is of interest to increase understanding of the function o

Increased Vitamin D intake differentiated according to skin color is needed to meet requirements in young Swedish children during winter : A double-blind randomized clinical trial

Background: Dark skin and low exposure to sunlight increase the risk of Vitamin D insufficiency in children. Objective: The aim of the study was to evaluate the amount of Vitamin D needed to ascertain that most children > 4 y of age attain sufficient serum25-hydroxyVitamin D [S-25(OH)D; i.e.,≥50 nmol/L] during winter regardless of latitude and skin color. Design: In a longitudinal, double-blind, r

Assessment of Cesarean hysterotomy scar before pregnancy and at 11–14 weeks of gestation : a prospective cohort study

Objective: To compare the appearance and measurement of Cesarean hysterotomy scar before pregnancy and at 11–14 weeks in a subsequent pregnancy. Methods: This was a prospective cohort study of women aged 18–35 years who had one previous Cesarean delivery (CD) at ≥ 37 weeks. Women were examined with saline contrast sonohysterography 6–9 months after CD. A scar defect was defined as large if scar th

Taxonomic review of the genus Capoeta Valenciennes, 1842 (Actinopterygii, Cyprinidae) from central Iran with the description of a new species

The genus Capoeta in Iran is highly diversified with 14 species and is one of the most important freshwater fauna components of the country. Central Iran is a region with high number of endemism in other freshwater fish species, though the present species was recognized as C. aculeata (Valenciennes, 1844), widely distributed within Kavir and Namak basins. However previous phylogenetic and phylogeo

Malignant melanoma is one of the most aggressive tumors which often gives metastasis to distant organs thereby limiting the chances of survival. Brain metastasis occurs in nearly half of the advanced tumors. In order to improve outcome early diagnosis is important. The discovery and better understanding of genetic and epigenetic changes is essential for developing new effective therapies, which ca

Virological failure and all-cause mortality in HIV-positive adults with low-level viremia during antiretroviral treatment

Although most HIV-infected individuals achieve undetectable viremia during antiretroviral therapy (ART), a subset have low-level viremia (LLV) of varying duration and magnitude. The impact of LLV on treatment outcomes is unclear. We investigated the association between LLV and virological failure and/or all-cause mortality among Swedish patients receiving ART. Methods HIV-infected patients from tw

Premorbid BMI predicts binge-purge symptomatology among individuals with anorexia nervosa

Objective: A finding consistent with the transdiagnostic approach to eating disorders is that about half of those with restricting anorexia nervosa (AN) eventually undergo a transition to the binge/purge (BP) subtype or to bulimia nervosa. Given evidence that individuals with bulimic symptoms exhibit elevated weights premorbidly, we tested the hypothesis that among those with AN, highest premorbid

Resonances in Axially Symmetric Dielectric Objects

A high-order convergent and robust numerical solver is constructed and used to find complex eigenwavenumbers and electromagnetic eigenfields of dielectric objects with axial symmetry. The solver is based on Fourier-Nyström discretization of combined integral equations for the transmission problem and can be applied to demanding resonance problems at microwave, terahertz, and optical wavelengths. H

Dietary starch intake modifies the relation between copy number variation in the salivary amylase gene and BMI

Background: Studies have shown conflicting associations between the salivary amylase gene (AMY1) copy number and obesity. Salivary amylase initiates starch digestion in the oral cavity; starch is a major source of energy in the diet. Objective: We investigated the association between AMY1 copy number and obesity traits, and the effect of the interaction between AMY1 copy number and starch intake o

Diversity and functions of intestinal mononuclear phagocytes

The intestinal lamina propria (LP) contains a diverse array of mononuclear phagocyte (MNP) subsets, including conventional dendritic cells (cDC), monocytes and tissue-resident macrophages (mÏ †) that collectively play an essential role in mucosal homeostasis, infection and inflammation. In the current review we discuss the function of intestinal cDC and monocyte-derived MNP, highlighting how these

The feasibility of salivary sample collection in an international pediatric cohort : The the TEDDY study

Saliva offers a relatively noninvasive method for measuring analytes such as cortisol, holding particular promise for use in pediatric populations on a large scale if a rigorous collection protocol is feasible in diverse settings. The Environmental Determinants of Diabetes in the Young study protocol, conducted in centers in the United States, Sweden, Finland, and Germany, used salivary collection

Cross-Cultural Validation of the Quality of Life in Hand Eczema Questionnaire (QOLHEQ)

The Quality of Life in Hand Eczema Questionnaire (QOLHEQ) is the only instrument assessing disease-specific health-related quality of life in patients with hand eczema. It is available in eight language versions. In this study we assessed if the items of different language versions of the QOLHEQ yield comparable values across countries. An international multicenter study was conducted with partici

Clinical practice of BOTOX® treatment for overactive bladder syndrome in Sweden : an assessment of resource use and external validity

Objective: The objective of this study was to assess the resource use of treating overactive bladder (OAB) patients in real-world clinical practice and to evaluate whether there is external validity in the treatment of OAB in clinical practice. Materials and methods: The study included 55 patients suffering from OAB and treated with BOTOX® at two Swedish clinics. The study was conducted as an anon

Reduced risk of reoperation after treatment of femoral neck fractures with total hip arthroplasty : A matched pair analysis

Background and purpose — Femoral neck fractures (FNFs) are commonly treated with some kind of arthroplasty, but evidence on whether to use hemiarthroplasty (HA) or total hip arthroplasty (THA) is lacking. HA reduces the risk of dislocation, but may lead to acetabular erosion. THA implies longer surgery and increased bleeding. THA may result in better function and health-related quality of life, bu

Critical evaluation of the Lund concept for treatment of severe traumatic head injury, 25 years after its introduction

When introduced in 1992, the Lund concept (LC) was the first complete guideline for treatment of severe traumatic brain injury (s-TBI). It was a theoretical approach, based mainly on general physiological principles-i.e., of brain volume control and optimization of brain perfusion and oxygenation of the penumbra zone. The concept gave relatively strict outlines for cerebral perfusion pressure, flu

Is a hollow centralizer necessary when using a polished, tapered, cemented femoral stem? : A randomized, controlled RSA study of 60 hips with 10 years of follow-up

Background and purpose — A tapered, polished and collarless stem is normally equipped with a hollow centralizer to prevent the stem from becoming end-bearing in the cement as the stem subsides. In a randomized clinical trial, we evaluated such a stem (MS-30), which was initially introduced with a solid centralizer but was later recommended to be fitted with a hollow centralizer. We hypothesized th
