Impact of distance from liver transplant centre on outcomes following liver transplantation: an Australian single-centre study.

Background: Access to liver transplantation (LT) is affected by geographic disparities. Higher waitlist mortality is observed in patients residing farther from LT centres, but the impact of distance on post-LT outcomes is unclear.

Aims: To evaluate whether the distance LT recipients reside from their LT centre affects graft and patient outcomes.

A Prospective Observational Cohort Study Comparing High-Complexity Against Conventional Pelvic Exenteration Surgery.

Conventional pelvic exenteration (PE) comprises the removal of all or most central pelvic organs and is established in clinical practise. Previously, tumours involving bone or lateral sidewall structures were deemed inoperable due to associated morbidity, mortality, and poor oncological outcomes. Recently however high-complexity PE is increasingly described and is defined as encompassing conventional PE with the additional resection of bone or pelvic sidewall structures.

Chemical characterization of polymer and chloride content in waste plastic materials using pyrolysis - direct analysis in real time - high-resolution mass spectrometry.

The increasing global demand for plastic has raised the need for effective waste plastic management due to its long lifetime and resistance to environmental degradation. There is a need for rapid plastic identification to improve the mechanical waste plastic sorting process. This study presents a novel application of Temperature-Programmed Desorption-Direct Analysis in Real Time-High Resolution Mass Spectrometry (TPD-DART-HRMS) that enables rapid characterization of various plastics.

Association of radiation-induced normal tissue toxicity with a high genetic risk for rheumatoid arthritis.

Purpose: Overlapping genes are involved with rheumatoid arthritis (RA) and DNA repair pathways. Therefore, we hypothesised that patients with a high polygenic risk score (PRS) for RA will have an increased risk of radiotherapy (RT) toxicity given the involvement of DNA repair.

Methods: Primary analysis was performed on 1494 prostate cancer, 483 lung cancer and 1820 breast cancer patients assessed for development of RT toxicity in the REQUITE study.

Molecular insights into the composition, sources, and aging of atmospheric brown carbon.

The light-absorbing chemical components of atmospheric organic aerosols are commonly referred to as Brown Carbon (BrC), reflecting the characteristic yellowish to brown appearance of aerosol. BrC is a highly complex mixture of organic compounds with diverse compositions and variable optical properties of its individual chromophores. BrC significantly influences the radiative budget of the climate and contributes to adverse air pollution effects such as reduced visibility and the presence of inhalable pollutants and irritants.

Professional-patient discrepancies in assessing lung cancer radiotherapy symptoms: An international multicentre study.

Background And Purpose: We investigate discrepancies in the assessment of treatment-related symptoms in lung cancer between healthcare professionals and patients, and factors contributing to these discrepancies.

Materials And Methods: Data from 515 participants in the REQUITE study were analysed. Five symptoms (cough, dyspnoea, bronchopulmonary haemorrhage, chest wall pain, dysphagia) were evaluated both before and after radiotherapy.

Respiratory Morbidity Before and During the COVID-19 Pandemic from Birth to 18 Months in a Swedish Birth Cohort.

Background: Respiratory infections in early life is one identified risk factor for asthma. We hypothesized that infection preventive measures during the COVID-19 pandemic influenced the risk of respiratory morbidity and aeroallergen sensitization in early childhood.

Objective: To compare respiratory morbidity and aeroallergen sensitization in children born before and during the pandemic.

The effect of time from surgery to commencing adjuvant radiotherapy for patients with head and neck squamous cell carcinoma.

Introduction: Studies reported inferior outcomes when radiotherapy starts >6-8 weeks post-surgery for head and neck squamous cell carcinoma (HNSCC) but are limited due to time variable dichotomization. We assessed the relationship between survival and the time between surgery and radiotherapy as a continuous variable, hypothesising there would be no change in patients' survival at 6-8 weeks post-surgery.

Methods/materials: Inclusion criteria: patients with HNSCC who underwent surgery and adjuvant (chemo)radiotherapy, Jan 2014-Dec 2020.

Evaluation of older patients with minor blunt head trauma to identify those who do not have clinically important traumatic brain injury and can be safely managed without cranial computed tomography.

Objective: Our primary aim was to identify a low-risk subgroup of older adults (aged 65 and older) presenting to ED with minor head trauma which can be safely managed without a cranial CT (cCT).

Methods: This was a single-site, prospective, observational, cohort study conducted at a major-referral ED. Alert, haemodynamically stable, older adults with suspected head trauma were eligible.

Postnatal maturation of serotonergic modulation of spinal RORβ interneurons in the medial deep dorsal horn.

Proprioceptive input is essential for coordinated locomotion and this input must be properly gated to ensure smooth and effective movement. Presynaptic inhibition mediated by GABAergic interneurons provides regulation of sensory afferent feedback. Serotonin not only promotes locomotion, but also modulates feedback from sensory afferents, both directly and indirectly, potentially by acting on the GABAergic interneurons that mediate presynaptic inhibition.

Association between rheumatoid arthritis and risk of radiotherapy toxicity: a systematic review.

Objective: There is sometimes concern over the use of radiotherapy for cancer in individuals with rheumatoid arthritis (RA), but little evidence to support its avoidance. Identifying any association between RA and risk of radiotherapy toxicity could impact current guidance. We aimed to review the evidence base.

Increasing Accessibility to Intradialytic Cycling in Rural and Remote Settings: Program Report.

Purpose Of Program: Access to exercise and rehabilitation is often lower in rural or remote areas and hemodialysis (HD) dependence imposes additional barriers. Intradialytic cycling (IDC) can improve HD-related symptoms, such as leg cramping, restless legs, and symptoms of depression, as well as physical function and fitness, but access to exercise professionals with this expertise is limited. To promote access to IDC in rural and remote HD units, we describe the implementation and initial evaluation of a novel IDC program using virtual assessment to safely prescribe and individualize IDC.

Novel antibodies detect nucleocytoplasmic O-fucose in protist pathogens, cellular slime molds, and plants.

Cellular adaptations to change often involve post-translational modifications of nuclear and cytoplasmic proteins. An example found in protists and plants is the modification of serine and threonine residues of dozens to hundreds of nucleocytoplasmic proteins with a single fucose (O-Fuc). A nucleocytoplasmic O-fucosyltransferase (OFT) occurs in the pathogen , the social amoeba , and higher plants, where it is called Spy because mutants have a spindly appearance.

HIV retesting among people living with HIV in Lesotho in 2022.

Background: Despite widespread HIV testing in sub-Saharan Africa, regular testing among at-risk populations is crucial for effective prevention. However, reports increasingly indicate retesting among people living with HIV (PLHIV), a group that would not require additional testing since they would already have received a confirmed diagnosis. We describe the demographic characteristics of PLHIV retesters in Lesotho, report the average number of HIV tests post-diagnosis among PLHIV, and share motivations for retesting.

Hypoxia-Associated Gene Signatures Are Not Prognostic in High-Risk Localized Prostate Cancers Undergoing Androgen Deprivation Therapy With Radiation Therapy.

Purpose: Men with high-risk prostate cancer (PCa) are treated with androgen deprivation therapy (ADT) and radiation therapy, but the disease reoccurs in 30% of patients. Biochemical recurrence of PCa after treatment is influenced by tumor hypoxia. Tumors with high levels of hypoxia are aggressive, resistant to treatment, and have increased metastatic capacity.

The relative branching fraction, with respect to the decay, is measured to be , where the first uncertainty is statistical, the second is systematic, and the third is related to the uncertainties in and .

A Preliminary Phenomenological Exploration of Experiences of the Empty Pelvis Syndrome Derived From a Modified-Delphi: The Price of Survival Following Pelvic Exenteration for Advanced Pelvic Cancer.

Objective: The empty pelvis syndrome (EPS) is common after pelvic exenteration (PE), causing fluid collections, bowel obstruction, perineal sinuses, and fistulas. The best approach to fill the pelvis to mitigate this remains controversial, and the impact of EPS on health-related quality of life (HrQoL) is unknown. This study is the first to begin to explore lived-experiences of EPS complications.

Sense of Belonging Among Medical Students, Residents, and Fellows: Associations With Burnout, Recruitment Retention, and Learning Environment.

Purpose: This study examines sense of belonging (belongingness) in a large population of medical students, residents, and fellows and associations with learner burnout, organizational recruitment retention indicators, and potentially modifiable learning environment factors.

Method: All medical students, residents, and fellows at Mayo Clinic sites were surveyed between October and November 2020 with items measuring sense of belonging in 3 contexts (school or program, organization, and surrounding community), burnout (2 Maslach Burnout Inventory items), recruitment retention indicators (likelihood of recommending the organization and accepting a job offer), potentially modifiable learning environment factors, and demographic factors (age, gender, race and ethnicity, LGBTQ+ identification, disability, and socioeconomic background).

Results: Of 2,257 learners surveyed, 1,261 (56%) responded.
