Quality assurance of internal mammary node irradiation in the DBCG IMN2 study.

Purpose/objective: The Danish Breast Cancer Group (DBCG) IMN2 study investigated the gain from internal mammary node irradiation (IMNI) in node-positive breast cancer patients. IMNI was indicated in right-sided patients, but not in left-sided. Target volume delineations were based on bony landmarks in contrast to the contemporary vessel-based ESTRO consensus guideline.

Respiratory Outcomes of Infants Born Extremely Preterm in the Necrotizing Enterocolitis Surgery Trial.

The multicenter Necrotizing Enterocolitis Surgery Trial compared initial peritoneal drainage with laparotomy among infants with extremely low birth weight and surgical necrotizing enterocolitis or intestinal perforation. In this post hoc analysis of trial data, initial drainage was associated with adverse respiratory outcomes, both in hospital and through 2 years corrected age.

Liberation from Respiratory Support in Bronchopulmonary Dysplasia.

Objective: To estimate the association between the mode of respiratory support administered at 36 weeks' post-menstrual age (PMA) with time-to-liberation from respiratory support (LRS) in infants with grade 2/3 bronchopulmonary dysplasia (BPD).

Study Design: Daily respiratory support data were abstracted for infants born <32 weeks' gestation with grade 2/3 BPD enrolled in the Children's Hospitals Neonatal Database between 2017 and 2022. The main exposure was the mode of respiratory support received at 36 weeks' PMA: high flow nasal cannula >2 L/min (HFNC), continuous positive airway pressure (CPAP), non-invasive positive pressure ventilation (NIPPV), or mechanical ventilation (MV).

Trends and disparities in violence-related injury morbidity among pregnant and postpartum individuals.

Purpose: Violence against pregnant and postpartum individuals is a major public health problem. Homicides during the perinatal period have recently increased, yet these deaths reflect only the most extreme manifestation of violence. Far less is known about trends and disparities in pregnancy-associated violence morbidity.

Transfers among Vulnerable Long-Term Nursing Home Residents.

Objectives: To determine whether the risk of nursing home-to-nursing home transfer is higher among long-term nursing home residents with intellectual and developmental disabilities (IDD), or serious mental illness (SMI), and/or Alzheimer's disease and related dementias (ADRD), relative to residents without these clinical diagnoses, and to assess the factors associated with transfer overall and for residents with these diagnoses.

Design: Cross-sectional cohort study of nursing home residents in 2019.

Setting And Participants: Michigan long-term nursing home residents identified from the Minimum Data Set.

Anti-Müllerian hormone as a predictor of oocyte yield following controlled ovarian stimulation in the rhesus macaque.

Anti-Müllerian hormone (AMH) is widely used in the clinic as a biomarker for ovarian reserve and to predict ovarian response to gonadotropin stimulation. Patients with higher AMH levels tend to yield more oocytes and have better outcomes from assisted reproductive technology (ART) procedures. The goal of this study is to determine if AMH can be used to predict the outcome of controlled ovarian stimulation in rhesus macaques, which are commonly used in biomedical research, to refine animal use while maximizing oocyte yield.

Digitizing the Appearance of 3D Printing Materials Using a Spectrophotometer.

The conventional approach to appearance prediction for 3D printed parts is to print a thin slab of material and measure its reflectance or transmittance with a spectrophotometer. Reflectance works for opaque printing materials. Transmittance works for transparent printing materials.

Comparison of Subdural and Intracortical Recordings of Somatosensory Evoked Responses.

Micro-electrocorticography (µECoG) electrodes have emerged to balance the trade-off between invasiveness and signal quality in brain recordings. However, its large-scale applicability is still hindered by a lack of comparative studies assessing the relationship between ECoG and traditional recording methods such as penetrating electrodes. This study aimed to compare somatosensory evoked potentials (SEPs) through the lenses of a µECoG and an intracortical microelectrode array (MEA).

Real-world effectiveness of CDK 4/6 inhibitors in estrogen-positive metastatic breast cancer.

Background: Initial treatment for advanced ER-positive/HER2-negative breast cancer involves a CDK 4/6 inhibitor (CDK 4/6i). Recent overall survival (OS) analyses led the Danish Medical Council to exclude palbociclib as preferred option. This study aimed to evaluate the real-world effectiveness of abemaciclib, palbociclib, and ribociclib in a Danish context.

Health-related quality of life predicts prognosis in individuals with COPD hospitalized with community-acquired pneumonia - a prospective cohort study.

Community-acquired pneumonia (CAP) in chronic obstructive pulmonary disease (COPD) often result in sudden and persistent reduction in health-related quality of life (HRQoL), which may be alleviated with palliative care. Among individuals with COPD, we aimed to investigate potential associations between HRQoL at admission with CAP and the risk of re-hospitalization and mortality and potential associations between specific HRQoL domains and CAP treatment outcomes. HRQoL was assessed at admission and the participants were grouped into tertiles based on the HRQoL utility index and specific domains.

Novel tools to quantify total, phospho-Ser129 and aggregated alpha-synuclein in the mouse brain.

Assays for quantifying aggregated and phosphorylated (S129) human α-synuclein protein are widely used to evaluate pathological burden in patients suffering from synucleinopathy disorders. Many of these assays, however, do not cross-react with mouse α-synuclein or exhibit poor sensitivity for this target, which is problematic considering the preponderance of mouse models at the forefront of pre-clinical α-synuclein research. In this project, we addressed this unmet need by reformulating two existing AlphaLISA SureFire Ultra™ total and pS129 α-synuclein assay kits to yield robust and ultrasensitive (LLoQ ≤ 0.

The association between being breastfed in infancy and risks of cancer in adulthood-a UK Biobank study.

Background: Being breastfed has established benefits for infant health, but its long-term effects on adult diseases, including cancer, remain underexplored. We examined associations between being breastfed in infancy and the risks of common cancers.

Methods: Data from 339,115 participants (191,117 women) enrolled in the UK Biobank with self-reported breastfeeding data were linked to national cancer registries.

A functional connection between the Microprocessor and a variant NEXT complex.

In mammalian cells, primary miRNAs are cleaved at their hairpin structures by the Microprocessor complex, whose core is composed of DROSHA and DGCR8. Here, we show that 5' flanking regions, resulting from Microprocessor cleavage, are targeted by the RNA exosome in mouse embryonic stem cells (mESCs). This is facilitated by a physical link between DGCR8 and the nuclear exosome targeting (NEXT) component ZCCHC8.

Vitamin K - content in food and dietary intake among the Danes.

Insufficient information on the content of vitamin K2 in our foods hinder estimation of the dietary intake. We aimed to establish content of eight vitamin K vitamers, vitamin K1 (phylloquinone; PK) and vitamin K2 (menaquinones; MK-4 to MK-10) in 88 composite food samples representing dairy, eggs, meat, fish, cereals, and plant-based alternatives to dairy. Combined with PK data for other foods, the dietary intake among Danes was estimated.

The intelligent diabetes telemonitoring using decision support to treat patients on insulin therapy (DiaTRUST) trial: study protocol for a randomized controlled trial.

Background: Diabetes affects 10.5% of adults globally, with type 2 diabetes accounting for 90-95% of cases. Achieving optimal glycemic control is crucial yet challenging, particularly with insulin therapy, where 30-50% of patients fail to meet treatment targets.

Contraception in Adolescents.

The adolescent care provider has a unique opportunity to provide young patients with appropriate counseling about sexual health and prevention of pregnancy and sexually transmitted infections. To provide high-quality sexual and reproductive health care for the adolescent, providers must be familiar with the breadth of contraceptive options and their characteristics. The purpose of this review is to discuss recent developments in contraception and to review commonly used contraceptive methods as they apply to adolescents.

α-Synuclein plastic antibody applied to monitor monomeric structures and discriminate aggregated forms in human CSF.

Aggregation of alpha-synuclein (aSyn) occurs in presynaptic neurons and constitutes a key factor for the progression of Parkinson's disease, emphasising the urgency of early detection to support effective treatment. Unfortunately, a reliable, sensitive and cost-effective diagnostic tool has so far been lacking. Thus, this work presents a novel biosensor for detecting aSyn using plastic antibodies coupled to electrochemical detection.

The Effectiveness of Digital Health Lifestyle Interventions on Weight Loss in People With Prediabetes: A Systematic Review, Meta-Analysis, and Meta-Regression.

Background: Digital health lifestyle interventions (DHLI) may offer scalable solutions to manage prediabetes in clinical practice; however, their effectiveness on people with prediabetes has not been systematically investigated and reviewed. Hence, in this systematic review, meta-analysis, and meta-regression the effectiveness of DHLI on prediabetes-related outcomes was investigated.

Methods: Four databases were searched to identify randomized controlled trials investigating the effectiveness of DHLI on adults with prediabetes published before 23 February 2024.
