Fertility restoration using autologous testicular tissue transplantation is relevant for infertile men surviving from childhood cancer and, possibly, in men with absent or incomplete spermatogenesis resulting in the lack of spermatozoa in the ejaculate (non-obstructive azoospermia, NOA). Currently, testicular tissue from pre-pubertal boys extracted before treatment with gonadotoxic cancer therapy

The development of Quantum Simulators, artificial platforms where the predictions of many-body theories of correlated quantum materials can be tested in a controllable and tunable way, is one of the main challenges of condensed matter physics. We introduce artificial lattices made of lead halide perovskite nanocubes as a new platform to simulate and investigate the physics of correlated quantum ma

Uncertainty analysis should be an integral part of conducting a scientific investigation of the damaging human health effects of exposure to chemicals. Sources of uncertainty related to limitations in knowledge are present in all steps of a such risk assessment, i.e. the hazard identification, hazard characterization and exposure assessment. The purpose of uncertainty analysis is to evaluate the c

AimsWe aimed to investigate the association between the exercise systolic blood pressure (SBP) response and future hypertension (HTN) in normotensive individuals referred for cycle ergometry, with special regard to reference exercise SBP values and exercise capacity.Methods and resultsIn this longitudinal cohort study, data from 14 428 exercise tests were cross-linked with Swedish national registr

Aim: The aim was to scrutinize the report in March 2023 that Sweden’s excess mortality was lowest in 2020–2022 compared with other European Union and Nordic countries, a report that received great national and international attention. Study design: Comparison of excess mortality in Sweden and Norway. Methods: Excess mortality for 2020–2022 was calculated for Sweden and Norway, the country with per

Background: Individuals with type 2 diabetes (T2D) are at increased risk of developing cardiovascular disease (CVD) which necessitates monitoring of risk factors and appropriate pharmacotherapy. This study aimed to identify factors predicting emergency department visits, hospitalizations, and mortality among T2D patients after being newly diagnosed with CVD. Methods: In a retrospective observation

Spondyloarthritis (SpA) has been associated with comorbidities, e.g., cardiovascular disease. However, little is known about the relation between SpA and chronic obstructive pulmonary disease (COPD). The aim of the study was to compare the prevalence of COPD in SpA to the general population. Patients with prevalent SpA in Skåne, Sweden, on December 31, 2018, were identified based on diagnostic cod

Background: Osteoporotic fractures pose a growing public health concern. Osteoporosis is underdiagnosed and undertreated, highlighting the necessity of systematic screening programs. We aimed to evaluate the effectiveness of a two-step population-based osteoporotic screening program. Methods: This ten-year follow-up of the Risk-stratified Osteoporosis Strategy Evaluation (ROSE) randomized trial te

Summary: Antiresorptive medications do not negatively affect fracture healing in humans. Teriparatide may decrease time to fracture healing. Romosozumab has not shown a beneficial effect on human fracture healing. Background: Fracture healing is a complex process. Uncertainty exists over the influence of osteoporosis and the medications used to treat it on fracture healing. Methods: Narrative revi

The role of human leukocyte antigen (HLA) class I and killer immunoglobulin-like receptor molecules in mediating acute retroviral syndrome (ARS) during human immunodeficiency virus type 1 (HIV-1) infection is unclear. Among 72 sub-Saharan African adults, HLA-A*23 was associated with lower odds of ARS (adjusted odds ratio, 0.10 [95% confidence interval, .01–.48]; P = .009), which warrants further s

The pHrodo with an “off–on” response to the changes of pH has been widely used as a fluorescent pH probe for bioimaging. The fluorescence off–on mechanism is fundamentally important for its application and further development. Herein, the sensing mechanism, especially the relevant excited-state dynamics, of pHrodo is investigated by steady-state and time-resolved spectroscopy as well as quant

Objective: To investigate the prevalence of diabetes retinopathy and evaluate the factors influencing its occurrence both at the onset of type 2 diabetes (T2D) and three years into its duration. Design: Retrospective population-based study. Setting: Data was retrieved from Regional Healthcare Information Platform in Region Halland 2016–2020. Subjects: Patients 35-75 years old in Region Halland rec

Background: To date, studies investigating the association between pre-biologic biomarker levels and post-biologic outcomes have been limited to single biomarkers and assessment of biologic efficacy from structured clinical trials. Aim: To elucidate the associations of pre-biologic individual biomarker levels or their combinations with pre-to-post biologic changes in asthma outcomes in real-life.

Objectives: To investigate the influence of genetic factors on persistence with treatment of early RA with MTX monotherapy. Methods: We conducted a genome-wide association study (GWAS) in a sample of 3902 Swedish early-RA patients initiating MTX in DMARD monotherapy as their first-ever DMARD. The outcome, short-and long-Term MTX treatment persistence, was defined as remaining on MTX at 1 and at 3

As humanity faces multiple mutually-reinforcing social-ecological crises, rhetoric on transformations abounds. However, transformations are normative, politically-contested processes that risk perpetuating, or even exacerbating, the ecological and socio-economic crises of today. We argue that transformations should seek to enhance human and non-human well-being within the planetary boundaries; a g

Hip and knee arthroplasties are mostly successful procedures; however, patient injuries may occur and should be reported to Löf, the Swedish patient insurance. This study investigated the incidence of patient injuries after primary total hip and knee arthroplasty in the Swedish regions, differences in incidence depending on annual surgical volume, and types of approved injuries. Approved patient i

Importance: Despite increased use of antibiotic-loaded bone cement (ALBC) in joint arthroplasty over recent decades, current evidence for prophylactic use of ALBC to reduce risk of periprosthetic joint infection (PJI) is insufficient. Objective: To compare the rate of revision attributed to PJI following primary total knee arthroplasty (TKA) using ALBC vs plain bone cement. Design, Setting, and Pa
