Monoamines' role in islet cell function and type 2 diabetes risk

The two monoamines serotonin and melatonin have recently been highlighted as potent regulators of islet hormone secretion and overall glucose homeostasis in the body. In fact, dysregulated signaling of both amines are implicated in β-cell dysfunction and development of type 2 diabetes mellitus (T2DM). Serotonin is a key player in β-cell physiology and plays a role in expansion of β-cell mass. Mela

IGFBP7 is upregulated in islets from T2D donors and reduces insulin secretion

Intra-islet crosstalk has become a focus area to fully understand the regulation of insulin secretion and impaired β-cell function in type 2 diabetes (T2D). Here, we put forward evidence for insulin-like growth factor binding protein 7 (IGFBP7) as a potential protein involved in autocrine and paracrine β-cell regulation. We showed presence of IGFBP7 in granules of both human α- and β-cells and mea

The “Pre-Rotating Dilator Technique” for Optimal Endograft Orientation in Complex Endovascular Aortic Repair

Purpose: To describe a novel technique for optimal orientation and accurate deployment of aortic endografts during complex endovascular aortic repair (cEVAR). Technique: After establishing the femoral access in the standard fashion, a long large-bore dilator is inserted before the cEVAR delivery system. The dilator is advanced beyond the renovisceral segment noticing the degree of axial rotation.

Treatment of Hip Displacement in Children with Cerebral Palsy : A 5-year Comparison of Proximal Femoral Osteotomy and Combined Femoral-Pelvic Osteotomy in 163 Children

Background: This study compared the 5-year outcomes of isolated proximal femoral varus osteotomy (FO) and combined proximal femoral varus and pelvic osteotomy (FPO) for the treatment of hip displacement in children with cerebral palsy (CP) in Sweden, focusing on the number of reoperations and residual hip displacement. Methods: The study included 163 children with a 5-year follow-up after FO or FP

A story of promising regime of concurrent Electro-Enhanced Chemo Radiation Immune Tumour-therapy

AbstraktSyftet med den här berättelsen handlar om Abskopal regression av subkutant implanterat N29 råttgliom som inträffar efter immunisering med syngena IFN-utsöndrande celler och behandling av kontralaterala tumörer med pulserande elektriska fält (PEF) och/eller strålbehandling (RT). Studien utfördes på råttor av Fischer-344-stammen med råttgliom N29-tumörer implanterade subkutant på flanken el

PRESERVING BRIGHT ELECTRON BEAMS : DISTORTED CSR KICKS

Short pulse, low emittance electron beams are necessary to drive bright FEL X-rays, for this reason it is important to preserve and limit emittance growth. The strong bunch compression required to achieve the short bunches, can lead to coherent synchrotron radiation (CSR)-induced emittance growth, and while there are some methods of CSR cancellation, these methods may be less effective when the CS

Cardiovascular dysautonomia in postacute sequelae of SARS-CoV-2 infection

Coronavirus disease 2019 (COVID-19) has led to a worldwide pandemic that continues to transform but will not go away. Cardiovascular dysautonomia in postacute sequelae of severe acute respiratory syndrome coronavirus 2 infection has led to persistent symptoms in a large number of patients. Here, we define the condition and its associated symptoms as well as potential mechanisms responsible. We pro

Nationwide Assessment of Patient Trajectories in Mantle Cell Lymphoma : The Swedish MCL complete Project

Mantle cell lymphoma (MCL) is a B-cell malignancy currently considered incurable. Although some patients obtain prolonged remission after first-line chemoimmunotherapy, many will need several treatment lines. Here, we present a nationwide assessment of treatment strategies, time to progression and survival in MCL. All patients diagnosed with MCL 2006-2018 were identified in the Swedish Lymphoma Re

Parents as protectors : Experiences during intact cord resuscitation in the mother's bed

Introduction: Intact cord resuscitation promotes zero separation and facilitates skin-to-skin contact, regardless of delivery mode. Therefore, this study aims to illuminate parents' experiences of intact cord resuscitation in the mother's bed. Method: Interviews with seven mothers, one father and seven couples were analysed using Lindseth and Norberg's phenomenological hermeneutics. Results: The a

Incidence and sequence of scoliosis and windswept hip deformity : which comes first in 4148 children with cerebral palsy? A longitudinal cohort study

Background: The aim was to analyse whether scoliosis or windswept hip deformity (WSH) occurs first for children with cerebral palsy (CP). Methods: This longitudinal cohort study using data from 1994 − 2020 (26 years) involved 41,600 measurements of 4148 children (2419 [58.3%] boys) with CP born 1990 − 2018 and registered into the Swedish CP follow-up program. Children were followed from a mean age

Exposure to comprehensive sexuality education in schools in South Africa : the implications on the uptake of HIV testing services among HIV positive adolescent girls

Comprehensive sexuality education (CSE) is seen as a key instrument through which to affect behaviour and improve sexual and reproductive health (SRH) outcomes amongst adolescents. However, few studies have to date evaluated key SRH outcomes following exposure to CSE within a school setting. This study estimates the association between CSE and HIV testing and HIV testing self-efficacy amongst HIV

Laparoscopic lavage vs primary resection for acute perforated diverticulitis : The SCANDIV randomized clinical trial

IMPORTANCE: Perforated colonic diverticulitis usually requires surgical resection, which is associated with significant morbidity. Cohort studies have suggested that laparoscopic lavage may treat perforated diverticulitis with less morbidity than resection procedures. OBJECTIVE: To compare the outcomes from laparoscopic lavage with those for colon resection for perforated diverticulitis. DESIGN, S

Sediment Records Shed Light on Drivers of Decadal Iron Concentration Increase in a Boreal Lake

Increasing iron (Fe) concentrations are found in lakes on a wide geographical scale but exact causes are still debated. The observed trends might result from increased Fe loading from the terrestrial catchment, but also from changes in how Fe distributes between the water column and the sediments. To get a better understanding of the causes we investigated whether there has been any change in the

RNA and metabolic disorders

Obesity is reaching levels never seen before in the world population, causing a rise in the incidence of metabolic disorders. The increase of visceral storage of adipose tissue is related to chronic inflammation and deregulation of the metabolism, causing insulin resistance, dyslipidemia and endothelial dysfunction. These pathologies, when they appear together, are known as metabolic syndrome and

Does lower educational attainment increase the risk of osteoarthritis surgery? a Swedish twin study

Background: Previous studies have reported an inverse association between educational attainment and different osteoarthritis (OA) outcomes. However, none of the previous studies have accounted for potential confounding by early-life environment and genetics. Thus, we aimed to examine the association between educational attainment and knee and hip OA surgery using twin data. Methods: From the Swed

On the symmetries of electrodynamic interactions

While mechanics was developed under the idea of reciprocal action (interactions), electromagnetism, as we know it today, takes a form more akin to unilateral action. Interactions call for spatial relations, unilateral action calls for space, just one reference centre. In contrast, interactions are matters of relations that require at least two centres. The development of the relational electromagn

Aminopeptidase activities as prospective urinary biomarkers for bladder cancer

Purpose: Proteases have been implicated in cancer progression and invasiveness. We have investigated the activities, as opposed to simple protein levels, of selected aminopeptidases in urine specimens to serve as potential novel biomarkers for urothelial cancer. Experimental design: The unique urinary proteomes of males and females were profiled to establish the presence of a gender-independent se

Predicting total knee arthroplasty from ultrasonography using machine learning

OBJECTIVE: To investigate the value of ultrasonographic data in predicting total knee replacement (TKR).DESIGN: Data from the Musculoskeletal Pain in Ullensaker study (MUST) was linked to the Norwegian Arthroplasty Register to form a 5-7 year prospective cohort study of 630 persons (69% women, mean (SD) age 64 (8.7) years). We examined the predictive power of ultrasound (US) features, i.e. osteoph
