Objective: To estimate inappropriate opioid dispensing in patients with knee or hip osteoarthritis (OA) defined as (1) dispensing of opioids within the first year of diagnosis or (2) long-term opioid use. Design: Data from Skåne Healthcare Register was linked with the Swedish Prescribed Drug Register. Incidence proportion of dispensed opioids within first year of incident knee or hip OA diagnosis

Introduction: Over the last decades, induction of labor has increased in many countries along with increasing maternal age. We assessed the effects of maternal age and labor induction on cesarean section at term among nulliparous and multiparous women without previous cesarean section. Material and methods: We performed a retrospective national registry-based study from Denmark, Finland, Iceland,

OBJECTIVE: A randomized controlled trial (RCT) was undertaken to determine the effect of negative pressure wound therapy (NPWT) on closed incisions after inguinal vascular surgery regarding surgical site infections (SSIs) and other wound complications. BACKGROUND: SSIs are a major concern in open vascular procedures involving the inguinal region. Prophylactic NPWT on closed incisions has shown pro

Context: Chronic breathlessness is a clinical syndrome that results in significant distress and disability. Morphine can reduce chronic breathlessness when the contributing etiologies are optimally treated. Objectives: Does oxycodone reduce chronic breathlessness compared with placebo? Methods: A multisite, randomized, placebo-controlled, double-blind, parallel-arm, fixed-dose trial of oral contro

The global rise in obesity and steady decline in sperm quality are two alarming trends that have emerged during recent decades. In parallel, evidence from model organisms shows that paternal diet can affect offspring metabolic health in a process involving sperm tRNA-derived small RNA (tsRNA). Here, we report that human sperm are acutely sensitive to nutrient flux, both in terms of sperm motility

Dark states are eigenstates or steady states of a system that are decoupled from the radiation. Their use, along with associated techniques such as stimulated Raman adiabatic passage, has extended from atomic physics, where it is an essential cooling mechanism, to more recent versions in the condensed phase where it can increase the coherence times of qubits. These states are often discussed in th

New nanomaterials are constantly developed with applications in everything from cosmetics to high tech electronics. Assessing their biological impact has been done by analysis of their adsorbed protein corona, in vitro cell assays, and larger scale ecotoxicological studies. This has proved to be a huge challenge due to the wide range of available nanomaterials and their unpredictable behaviour in

Obesity has been associated with upper gastrointestinal cancers; however, there are limited prospective data on associations by subtype/subsite. Obesity can impact hormonal factors, which have been hypothesized to play a role in these cancers. We investigated anthropometric and reproductive factors in relation to esophageal and gastric cancer by subtype and subsite for 476,160 participants from th

In this work, we present a detailed investigation of the growth of palladium-seeded GaAs nanowires. Nanowires grown on GaAs (111)B substrates consist of three different morphologies, denoted as curly (containing multiple kinks), inclined (relative to the substrate, such as 〈001〉), and vertical. We show that the relative yield of the different types is controllable by a combination of V/III ratio a

According to current models of hematopoiesis, lymphoid-primed multi-potent progenitors (LMPPs) (Lin(-)Sca-1(+)c-Kit(+)CD34(+)Flt3(hi)) and common myeloid progenitors (CMPs) (Lin(-)Sca-1(+)c-Kit(+)CD34(+)CD41(hi)) establish an early branch point for separate lineage-commitment pathways from hematopoietic stem cells, with the notable exception that both pathways are proposed to generate all myeloid

BACKGROUND AND OBJECTIVE: Severe idiopathic pulmonary fibrosis is associated with an increased risk of cardiovascular disease and gastro-oesophageal reflux, which may influence prognosis. We evaluated associations between cardiovascular and antacid medications, and mortality, in oxygen-dependent pulmonary fibrosis (PF) of unknown cause.METHODS: Prospective population-based study of adults starting

Ischemic stroke is often associated with loss of cortical neurons leading to various neurological deficits. A cell replacement based on stem cell transplantation to repair the damaged brain requires the generation of specific neuronal subtypes. Recently, induced pluripotent stem cells have been used to generate various subtypes of neurons in vitro for transplantation in stroke-damaged brains. Howe

Hematopoietic stem cells (HSCs) compose a rare population of undifferentiated cells, residing in the bone marrow of adult individuals, ensuring life-long maintenance and replenishment of the blood system. This fantastic achievement is possible owing to two special characteristics of the HSCs: their ability to make copies of themselves (self-renew), and their capacity to differentiate to all lineag

Prospective studies examining the association between coffee and tea consumption and gastric cancer risk have shown inconsistent results. We investigated the association between coffee (total, caffeinated and decaffeinated) and tea consumption and the risk of gastric cancer by anatomical site and histological type in the European Prospective Investigation into Cancer and Nutrition study. Coffee an

The society of today is highly dependent on technical infrastructures. Several incidents around the world the last decades have clearly highlighted the major effects technical infrastructure breakdowns have on life, health and economy of society. The vulnerabilities inherent in our technical infrastructures must be addressed in a proactive manner; it is not feasible to wait for major incidents to

Background: Medical advancements have resulted in better survival and life expectancy among those with spina bifida, but a significantly increased risk of perinatal and postnatal mortality for individuals with spina bifida remains. Objectives: To examine stillbirth and infant and child mortality among those affected by spina bifida using data from multiple countries. Methods: We conducted an obser

Dion–Jacobson (DJ) type 2D perovskites with a single organic cation layer exhibit a narrower distance between two adjacent inorganic layers compared to the corresponding Ruddlesden–Popper perovskites, which facilitates interlayer charge transport. However, the internal crystal structures in 2D DJ perovskites remain elusive. Herein, in a p-xylylenediamine (PDMA)-based DJ perovskite bearing bifuncti

A common molecular design paradigm for optical power limiting (OPL) applications is to introduce heavy atoms that promote intersystem crossing and triplet excited states. In order to investigate this effect, three multi-branched fluorene molecules were prepared where the central moiety was either an organic benzene unit, para-dibromobenzene, or a platinum(II)-alkynyl unit. All three molecules show
