Methodological challenges when doing research that includes ethnic minorities : a scoping review

Background: There are challenging methodological issues in obtaining valid and reliable results on which to base occupational therapy interventions for ethnic minorities. The aim of this scoping review is to describe the methodological problems within occupational therapy research, when ethnic minorities are included. Method: A thorough literature search yielded 21 articles obtained from the scien

Proteomic analysis of breast tumors confirms the mRNA intrinsic molecular subtypes using different classifiers : A large-scale analysis of fresh frozen tissue samples

Background: Breast cancer is a complex and heterogeneous disease that is usually characterized by histological parameters such as tumor size, cellular arrangements/rearrangments, necrosis, nuclear grade and the mitotic index, leading to a set of around twenty subtypes. Together with clinical markers such as hormone receptor status, this classification has considerable prognostic value but there is

The Association Between Psychiatric Disorders and Telomere Length : A Meta-Analysis Involving 14,827 Persons

OBJECTIVE: This study examined the relationship between leukocyte telomere length (LTL), a marker of cell aging, and psychiatric disorders in adults compared with controls using meta-analytic methods. METHODS: Data were abstracted from studies examining the relationship between LTL and adult psychiatric disorders. In addition to an overall estimate of effect size, subgroup analyses and meta-regres

Urinary biomarkers in pediatric appendicitis

Purpose: The diagnosis of pediatric appendicitis is still a challenge, resulting in perforation and negative appendectomies. The aim of this study was to evaluate novel biomarkers in urine and to use the most promising biomarkers in conjunction with the Pediatric Appendicitis Score (PAS), to see whether this could improve the accuracy of diagnosing appendicitis. Methods: A prospective study of chi

Amount of stroma is associated with mammographic density and stromal expression of oestrogen receptor in normal breast tissues

Following female sex and age, mammographic density is considered one of the strongest risk factors for breast cancer. Despite the association between mammographic density and breast cancer risk, little is known about the underlying histology and biological basis of breast density. To better understand the mechanisms behind mammographic density we assessed morphology, proliferation and hormone rece

Home- or Institutional Hemodialysis? - a Matched Pair-Cohort Study Comparing Survival and Some Modifiable Factors Related to Survival

Background/Aims: Survival for dialysis patients is poor. Earlier studies have shown better survival in home-hemodialysis (HHD). The aims of this study are to compare survival for matched patients with HHD and institutional hemodialysis (IHD) and to elucidate the effect on factors related to survival such as hyperphosphatemia, fluid overload and anemia. Methods: In this retrospective, observational

Vertebrate TFPI-2 C-terminal peptides exert therapeutic applications against Gram-negative infections

Background: Tissue factor pathway inhibitor-2 (TFPI-2) is a serine protease inhibitor that exerts multiple physiological and patho-physiological activities involving the modulation of coagulation, angiogenesis, tumor invasion, and apoptosis. In previous studies we reported a novel role of human TFPI-2 in innate immunity by serving as a precursor for host defense peptides. Here we employed a number

Measuring factor IX activity of nonacog beta pegol with commercially available one-stage clotting and chromogenic assay kits : A two-center study

Essentials: Validated assays are required to precisely measure factor IX (FIX) activity in FIX products. N9-GP and two other FIX products were assessed in various coagulation assay systems at two sites. Large variations in FIX activity measurements were observed for N9-GP using some assays. One-stage and chromogenic assays accurately measuring FIX activity for N9-GP were identified. Summary: Backg

A patient with non-ST-segment elevation acute coronary syndrome : Is it possible to predict the culprit coronary artery?

In acute coronary syndromes without ST-segment elevation (NSTE-ACS), identification of the culprit artery is, most often, not possible. In this case report, we elaborate on the likelihood of different culprit arteries in a patient with NSTE-ACS. While her symptoms were progressing, typical ECG findings of ischemia in the left coronary territories were diminishing. Instead, dynamic T-wave changes i

Programme characteristics and everyday occupations in day centres and clubhouses in Sweden

Background: Meaningful everyday occupations are important for mental health and recovery and are provided by both community-based day centres (DCs) and clubhouses. It is unknown, however, if any of the two has more recovery-promoting features. Objective: This nine-month longitudinal study compared DC and clubhouses, concerning the users’ perceptions of unit and programme characteristics, and aspec

Prevalence of Dementia With Lewy Body Symptoms : A Cross-Sectional Study in 40 Swedish Nursing Homes

Objectives: To investigate and establish the prevalence of dementia with Lewy body (DLB) symptoms in all nursing home (NH) residents in Malmö, the third largest city in Sweden. DLB is a neurocognitive disorder with core features, such as parkinsonism, visual hallucinations, and fluctuating cognition/excessive daytime sleepiness, and supportive features, such as rapid eye movement sleep behavior di

CART is overexpressed in human type 2 diabetic islets and inhibits glucagon secretion and increases insulin secretion

Aims/hypothesis: Insufficient insulin release and hyperglucagonaemia are culprits in type 2 diabetes. Cocaine- and amphetamine-regulated transcript (CART, encoded by Cartpt) affects islet hormone secretion and beta cell survival in vitro in rats, and Cart−/− mice have diminished insulin secretion. We aimed to test if CART is differentially regulated in human type 2 diabetic islets and if CART affe

A cohort study of 59 children, focusing on foot involvement and the contralateral foot

Background and purpose — Idiopathic clubfoot can be bilateral or unilateral; however, most studies of gait have assessed clubfoot cases as one uniform group. The contralateral foot in children with unilateral clubfoot has shown deviations in pedobarographic measurements, but it is seldom included in studies of gait. We evaluated gait in children with idiopathic clubfoot, concentrating on foot invo

Effects of aspirin on risk and severity of early recurrent stroke after transient ischaemic attack and ischaemic stroke : Time-course analysis of randomised trials

Background: Aspirin is recommended for secondary prevention after transient ischaemic attack (TIA) or ischaemic stroke on the basis of trials showing a 13% reduction in long-term risk of recurrent stroke. However, the risk of major stroke is very high for only the first few days after TIA and minor ischaemic stroke, and observational studies show substantially greater benefits of early medical tre

Milk miRNAs : Simple nutrients or systemic functional regulators?

Milk is rich in miRNAs that appear to play important roles in the postnatal development of all mammals. Currently, two competing hypotheses exist: the functional hypothesis, which proposes that milk miRNAs are transferred to the offspring and exert physiological regulatory functions, and the nutritional hypothesis, which suggests that these molecules do not reach the systemic circulation of the mi

Phonology in Swedish-speaking 3-year-olds born with unilateral cleft lip and palate treated with palatal closure in one or two stages

Background: Phonological disorders are common in 3-year-olds born with cleft palate compared to non-cleft peers. However, published results have been based on small samples. The purpose was to expand the knowledge on phonology of Swedish-speaking 3-year-olds with unilateral cleft lip and palate (UCLP), treated with primary palatal closure in one or two stages. Methods: The phonology of 26 children

A model to estimate vertical speed of ascending evacuation from maximal work capacity data

This paper describes the development of an ascending evacuation model based on physical work capacity of a selected sample. The model is based on the combination of several field experiments, existing databases and pre-tests that were combined to define initial test conditions in the laboratory environment on a step machine. Maximal oxygen consumption (VO2max) of 13 male and 12 female subjects (da

Negative-Ion/Positive-Ion Coincidence Yields of Core-Excited Water

We report yields of mass-resolved negative ions and positive ions measured in coincidence after core-excitation of water molecules. The analysis of negative-ion/positive-ion and negative-ion/positive-ion/positive-ion coincidence events provides new information on pathways leading to negative ion production, enhancing the present understanding of the dissociation processes of the water molecule. Di

Brood size constrains the development of endothermy in blue tits

Altricial birds are unable to maintain body temperature when exposed to low ambient temperatures during the first days after hatching. Thermoregulatory capacity begins to form as postnatal development progresses, and eventually nestlings become homeothermic. Several factors may influence this development at both the level of the individual and the level of the whole brood, but to our knowledge no
