NMR spectroscopy derived plasma biomarkers of inflammation in human populations: Influences of age, sex and adiposity.

Understanding the distribution and variation in inflammatory markers is crucial for advancing our knowledge of inflammatory processes and evaluating their clinical utility in diagnosing and monitoring acute and chronic disease. 1H NMR spectroscopy of blood plasma and serum was applied to measure a composite panel of inflammatory markers based on acute phase glycoprotein signals (GlycA and GlycB) and sub-regions of the lipoprotein derived Supramolecular Phospholipid Composite signals (SPC1, SPC2 and SPC3) to establish normal ranges in two healthy, predominantly white cohorts from Australia (n = 398) and Spain (n = 80; ages 20-70 years). GlycA, GlycB, SPC1 and SPC3 were not significantly impacted by age or sex, but SPC2 (an HDL-related biomarker) was significantly higher in women across all age ranges by an average of 33.

Postoperative complications and cost implications in sickle cell disease patients undergoing total hip arthroplasty: A national inpatient sample study.

Background: Sickle cell disease (SCD) is a genetic condition affecting approximately 5 % of the global population, with significant prevalence in sub-Saharan Africa and an estimated 89,079 cases in the United States. Osteonecrosis, particularly of the femoral head (ONFH), is a common orthopaedic complication in SCD, often requiring total hip arthroplasty (THA) when conservative treatments fail. While THA can improve pain and function, it carries significant perioperative risks, with complication rates in patients with SCD as high as 67 %.

Ultrahypofractionated Adjuvant Breast Radiation Therapy (± Boost) and Virtual Consultations: Patient Perspectives at 1 Year.

Purpose: In March 2020, a 1-week ultrahypofractionated adjuvant breast radiation therapy schedule, 26 Gy in 5 fractions, and telehealth were adopted to reduce the risk of COVID-19 for staff and patients. This study describes real-world 1-year late toxicity for ultrahypofractionation (including a sequential boost) and patient perspectives on this new schedule and telehealth workflows.

Methods And Materials: Consecutive patients were enrolled between March and August 2020.

Clinical prediction of wound re-epithelisation outcomes in non-severe burn injury using the plasma lipidome.

Whilst wound repair in severe burns has received substantial research attention, non-severe burns (<20 % total body surface area) remain relatively understudied, despite causing considerable physiological impact and constituting most of the hospital admissions for burns. Early prediction of healing outcomes would decrease financial and patient burden, and aid in preventing long-term complications from poor wound healing. Lipids have been implicated in inflammation and tissue repair and may play essential roles in burn wound healing.

DNA Barcoding for the Identification of Adult Mosquitoes (Diptera: Culicidae) in Western Australia.

Precise mosquito identification is integral to effective arbovirus surveillance. Nonetheless, the conventional morphological approach to identifying mosquito species is laborious, demands expertise and presents challenges when specimens are damaged. DNA barcoding offers a promising alternative, surmounting challenges inherent in morphological identification.

Optogenetic activation of mesencephalic projections to the nucleus accumbens shell impairs probabilistic reversal learning by disrupting learning from negative reinforcement.

Cognitive flexibility, the capacity to adapt behaviour to changes in the environment, is impaired in a range of brain disorders, including schizophrenia and Parkinson's disease. Putative neural substrates of cognitive flexibility include mesencephalic pathways to the ventral striatum (VS) and dorsomedial striatum (DMS), hypothesized to encode learning signals needed to maximize rewarded outcomes during decision-making. However, it is unclear whether mesencephalic projections to the ventral and dorsal striatum are distinct in their contribution to flexible reward-related learning.

Evaluation of variation in preclinical electroencephalographic (EEG) spectral power across multiple laboratories and experiments: An EQIPD study.

The European Quality In Preclinical Data (EQIPD) consortium was born from the fact that publications report challenges with the robustness, rigor, and/or validity of research data, which may impact decisions about whether to proceed with further preclinical testing or to advance to clinical testing, as well as draw conclusions on the predictability of preclinical models. To address this, a consortium including multiple research laboratories from academia and industry participated in a series of electroencephalography (EEG) experiments in mice aimed to detect sources of variance and to gauge how protocol harmonisation and data analytics impact such variance. Ultimately, the goal of this first ever between-laboratory comparison of EEG recordings and analyses was to validate the principles that supposedly increase data quality, robustness, and comparability.

3-Factor prothrombin complex concentrate versus 4-factor prothrombin complex concentrate for the reversal of oral factor Xa inhibitors.

Multiple agents exist for the reversal of oral Factor Xa inhibitor (FXa) associated bleeding, including Coagulation FXa Recombinant, Inactivated zhzo (andexanet alfa) and 4-factor prothrombin complex concentrate (4F-PCC). While classified as a 3F-PCC product, Profilnine contains up to 35 IU of Factor VII (per 100 IU of Factor IX) in addition to therapeutic levels of Factors II, IX, and X, and has demonstrated a similar impact on prothrombin time and blood product usage in non-warfarin related bleeding. This was a retrospective, multicenter study at four medical centers of adult patients who presented with major bleeding associated with oral FXa inhibitors and received either 4F-PCC (n = 64) or 3F-PCC (n = 61).

Central nervous system tumors in adolescents and young adults: A Society for Neuro-Oncology consensus review on diagnosis, management, and future directions.

Adolescents and young adults (AYAs; ages 15-39 years) are a vulnerable population facing challenges in oncological care, including access to specialized care, transition of care, unique tumor biology, and poor representation in clinical trials. Brain tumors are the second most common tumor type in AYA, with malignant brain tumors being the most common cause of cancer-related death. The 2021 WHO Classification for central nervous system (CNS) Tumors highlights the importance of integrated molecular characterization with histologic diagnosis in several tumors relevant to the AYA population.

Resource implications of evolving breast cancer radiotherapy treatment protocols.

• Updated breast cancer adjuvant radiotherapy treatment protocols resulted in a reduction of staff time (linac and non-linac) and overall resource costs. • The introduction of ultrahypofractionated 26Gy/5 radiotherapy resulted in the greatest saving of resource costs, €47,489, and staff time, 13,820 min. • Expanded use of IMN radiotherapy resulted in the largest increase in resource costs, €7,612, and staff time, 11,345 min.

A systematic review of the use of unannounced standardized patients (USPs) in clinical settings: A call for more detailed quality and fidelity descriptions and expansion to new areas.

Background: Unannounced standardized patients (USPs) have long been used to measure clinical performance in situ. These incognito actors capture data on clinician skills during an encounter, as well as patient experience more broadly. A robust USP program requires extensive preparation and standardization efforts.

Merging Natural Product Structures with Pharmaceutical Leads: Unnatural Enantiomers of Estranes as Glucocorticoid Receptor Modulators That Suppress TNF-α and IL-6 Release.

Natural products are widely recognized as valuable starting points for the development of therapeutics, with synthetic tetracyclic triterpenoids (e.g., steroids) being the most well represented among the drugs approved by the Food and Drug Administration.

Chest CT Airway and Vascular Measurements in Females with COPD or Long-COVID.

Chest CT provides a way to quantify pulmonary airway and vascular tree measurements. In patients with COPD, CT airway measurement differences in females are concomitant with worse quality-of-life and other outcomes. CT total airway count (TAC), airway lumen area (LA), and wall thickness (WT) also differ in females with long-COVID.

Unmasking anxiety: a head-to-head comparison of open and closed masks in head and neck cancer radiotherapy.

Background: Facemasks accurately immobilise patients with head and neck cancer (HNC) receiving radiotherapy (RT). However, such masks are associated with treatment related distress, a prognostic factor for poorer survival. Open masks offer increased comfort and patient satisfaction.

Intrafraction Motion in Surface-Guided Breast Radiation Therapy and its Implications on a Single Planning Target Volume Margin Strategy.

Purpose: This study quantifies intrafraction motion in surface-guided radiation therapy (SGRT) for breast cancer and considers the need for individualized intrafraction motion measures when calculating planning target volume (PTV) margins.

Methods And Materials: SGRT was used to assess intrafraction motion in consecutive patients according to (1) site irradiated (whole-breast/chest wall vs whole-breast/chest wall + regional lymph nodes) and (2) the use of deep inspiration breath hold versus free breathing. Intrafraction motion variation was evaluated throughout the treatment course for all cases.

Gender Differences in Citation Rate: An Analysis of Randomized Controlled Trials in Nephrology High-Impact Journals Over Two Decades.

Key Points: Among the studies included, women were first authors of minority of the publications, and this trend persisted over the 20 years. Crude citation rates were lower in papers with female first authors; the gender of the author was not independently associated with citation metrics.

Background: Historically, women's scientific contributions have been under-recognized.

Advancing Health Policy and Outcomes for People With Intellectual or Developmental Disabilities: A Community-Led Agenda.

People with IDD experience considerably higher rates of poor overall health, chronic conditions including diabetes, mental health challenges, maternal mortality, and preventable deaths. This Special Communication proposes national goals based on a community-led consensus model that advances priority health outcomes for people with IDD and their caregivers/partners and identifies critical policy opportunities and challenges in achieving these goals.

The ParentingWell Practice Approach: Facilitating implementation in U.S. adult mental health services.

Background: To address the need for interventions for families with parents with mental illness, the evidence-based intervention Let's Talk about Children (LTC) was adapted in the context of adult mental health services in the United States and reframed as the ParentingWell Practice Approach. This study focuses on the early implementation phase of the adapted practice in Massachusetts.

Methods: As part of the adaptation and implementation process, practitioners from provider agencies serving adults with mental illness were invited to participate in the ParentingWell Learning Collaborative (PWLC), which included in-person learning collaborative sessions and follow-up virtual coaching sessions.

Revision Total Hip Arthroplasty: Evaluating the Utility of the Geriatric Nutritional Risk Index as a Risk Stratification Tool.

Background: This study investigates the association between the Geriatric Nutritional Risk Index (GNRI), a measure of malnutrition risk, and 30-day postoperative complications following revision total hip arthroplasty (rTHA).

Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients ≥65 who underwent aseptic rTHA between 2015 and 2021. The final study population (n = 7119) was divided into 3 groups based on preoperative GNRI: normal/reference (GNRI >98) (n = 4342), moderate malnutrition (92 ≤ GNRI ≤98) (n = 1367), and severe malnutrition (GNRI <92) (n = 1410).
