Verification imaging in prostate MR-only radiotherapy: Are fiducial markers necessary?

Purpose/objective: MR-only radiotherapy planning exploits the benefits of MRI soft-tissue delineation, whilst negating the registration inaccuracies caused by MRI CT fusion. Fiducial markers have conventionally been used in prostate radiotherapy to reduce on-treatment image matching variability. However, this is an invasive procedure for the patient, and presents technical difficulties in an MR-only pathway as fiducial markers are difficult to visualise on MRI.

Objective: To design and assess a visual genomic explainer focusing on plain language and engaging imagery. The explainer aimed to support doctors' comprehension of complex genomic concepts and results and act as a resource promoting the integration of genomic testing into mainstream care.

Design: Prospective genomic resource development and questionnaire.

Temperature influences immune cell development and body length in purple sea urchin larvae.

Anthropogenic climate change has increased the frequency and intensity of marine heatwaves that may broadly impact the health of marine invertebrates. Rising ocean temperatures lead to increases in disease prevalence in marine organisms; it is therefore critical to understand how marine heatwaves impact immune system development. The purple sea urchin (Strongylocentrotus purpuratus) is an ecologically important, broadcast-spawning, omnivore that primarily inhabits kelp forests in the northeastern Pacific Ocean.

Motor Learning in a Complex Motor Task Is Unaffected by Three Consecutive Days of Transcranial Alternating Current Stimulation.

Transcranial alternating current stimulation (tACS) delivered to the primary motor cortex (M1) can increase cortical excitability, entrain neuronal firing patterns, and increase motor skill acquisition in simple motor tasks. The primary aim of this study was to assess the impact of tACS applied to M1 over three consecutive days of practice on the motor learning of a challenging overhand throwing task in young adults. The secondary aim was to examine the influence of tACS on M1 excitability.

Exploring the Influence of Inter-Trial Interval on the Assessment of Short-Interval Intracortical Inhibition.

Short-interval intracortical inhibition (SICI) is a common paired-pulse transcranial magnetic stimulation (TMS) measure used to assess primary motor cortex (M1) interneuron activity in healthy populations and in neurological disorders. Many of the parameters of TMS stimulation to most accurately measure SICI have been determined. However, one TMS parameter that has not been investigated is the time between SICI trials (termed inter-trial interval; ITI).

Quantifying Nipple-Areolar Complex Shape and Location After Transmasculine Top Surgery: A Study of Postoperative Photographs Posted on Social Media and Surgeons' Professional Websites.

Purpose: The transgender community utilizes online platforms to view and share postoperative masculinizing top surgery photographs. However, the quantitative and qualitative nature of these photographs is unknown. We aimed to conduct an analysis of postoperative online photographs for nipple-areolar complex (NAC) shape and location, and compare social media platforms to World Professional Association for Transgender Health (WPATH) surgeons' websites and published cis-male chest proportions.

Are Your Patients Safe to Mobilize Alone in Their Room? The Johns Hopkins Hospital In-Room Independence Scale.

Objective: Given the stigma of falls while hospitalized, inpatient rehabilitation facilities often restrict the independent room mobility of their patients. We assessed the psychometric properties of a new tool, the Johns Hopkins In-Room Independence Scale, to evaluate its effectiveness at identifying independence for in-room mobility.

Design: Construct validity was assessed by comparing the Johns Hopkins In-Room Independence Scale to its "gold standard" counterparts, The Johns Hopkins Falls Risk Assessment Tool, the Activity Measure for Post-Acute Care Mobility and Activity, and the Centers for Medicare Quality Indicators.

The Influence of Different Inter-Trial Intervals on the Quantification of Intracortical Facilitation in the Primary Motor Cortex.

Intracortical facilitation (ICF) is a paired-pulse transcranial magnetic stimulation (TMS) measurement used to quantify interneuron activity in the primary motor cortex (M1) in healthy populations and motor disorders. Due to the prevalence of the technique, most of the stimulation parameters to optimize ICF quantification have been established. However, the underappreciated methodological issue of the time between ICF trials (inter-trial interval; ITI) has been unstandardized, and different ITIs have never been compared in a paired-pulse TMS study.

Cerebellar Transcranial Direct Current Stimulation Applied over Multiple Days Does Not Enhance Motor Learning of a Complex Overhand Throwing Task in Young Adults.

Cerebellar transcranial direct current stimulation (tDCS) enhances motor skill and learning in relatively simple motor tasks, but it is unclear if c-tDCS can improve motor performance in complex motor tasks. The purpose of this study was to determine the influence of c-tDCS applied over multiple days on motor learning in a complex overhand throwing task. In a double-blind, randomized, between-subjects, SHAM-controlled, experimental design, 30 young adults were assigned to either a c-tDCS or a SHAM group.

Pharmacokinetics and Safety of Twice-daily Ritonavir-boosted Atazanavir With Rifampicin.

Background: Critical drug-drug interactions (DDI) and hepatotoxicity complicate concurrent use of rifampicin and protease inhibitors. We investigated whether dose escalation of atazanavir/ritonavir could safely overcome the DDI with rifampicin.

Methods: DERIVE (NCT04121195, EDCTP) was a dose-escalation trial in people with human immunodeficiency virus (HIV) on atazanavir/ritonavir-based antiretroviral therapy (ART) in Uganda.

Transcranial Direct Current Stimulation of Primary Motor Cortex over Multiple Days Improves Motor Learning of a Complex Overhand Throwing Task.

Transcranial direct current stimulation (tDCS) applied to the primary motor cortex (M1) improves motor learning in relatively simple motor tasks performed with the hand and arm. However, it is unknown if tDCS can improve motor learning in complex motor tasks involving whole-body coordination with significant endpoint accuracy requirements. The primary purpose was to determine the influence of tDCS on motor learning over multiple days in a complex over-hand throwing task.

BMI is Not Associated with Chest-Specific Body Image, Complications or Revisions in Gender-Affirming Mastectomy: A Single-Center Cross-Sectional Study.

Objective: To analyze the impact of Body Mass Index (BMI) on clinical and patient-reported outcomes following gender-affirming mastectomy (GM).

Background: BMI is a barrier for obese patients seeking GM despite increasing evidence that it is safe in this population. Currently little is known about the impact of BMI on chest-specific body image and satisfaction following GM.

Support for management actions to protect night sky quality: Insights from visitors to state and national park units in the U.S.

Light pollution is a global phenomenon where anthropogenic light sources continue to grow unabated, affecting both social and ecological systems. This is leaving parks and protected areas as some of the last vestiges of naturally dark environments for protecting views of the night sky. Yet, even parks and protected areas have outdoor lighting.

Low gestational weight gain (+2.0 to 4.9 kg) for singleton-term gestations associated with favorable perinatal outcomes for all prepregnancy obesity classes.

Background: Previous studies that evaluated low gestational weight gain or weight loss among prepregnancy obesity classes have not determined the amount of gestational weight gain associated with the lowest risk of adverse perinatal outcomes and neonatal morbidity among singleton term births.

Objective: This study aimed to evaluate the relationship of specific gestational weight gain categories of weight loss, stable weight, and low gain considered below the 2009 Institute of Medicine guidelines to perinatal outcomes and neonatal morbidity for singleton, term live births among prepregnancy obesity classes.

Study Design: This was a retrospective cohort study of 18,476 women among 3 classes of prepregnancy obesity, based on measured prepregnancy weight, and delivering a live singleton pregnancy at ≥37 weeks of gestation at a Kaiser Permanente Northern California hospital (2009-2012).

Long-Term Regret and Satisfaction With Decision Following Gender-Affirming Mastectomy.

Importance: There has been increasing legislative interest in regulating gender-affirming surgery, in part due to the concern about decisional regret. The regret rate following gender-affirming surgery is thought to be approximately 1%; however, previous studies relied heavily on ad hoc instruments.

Objective: To evaluate long-term decisional regret and satisfaction with decision using validated instruments following gender-affirming mastectomy.

Clinical profiling of specific diagnostic subgroups of women with chronic pelvic pain.

Introduction: Chronic pelvic pain (CPP) is a common condition affecting up to 26.6% of women, with many suffering for several years before diagnosis and/or treatment. Its clinical presentation is varied and there are frequently comorbid conditions both within and outside the pelvis.

Outcomes of breast reconstruction in patients with stage IV breast cancer.

Background: Patients with Stage IV breast cancer are living longer but breast reconstruction in this setting remains controversial. There is limited research evaluating the benefits of breast reconstruction in this patient cohort.

Study Design: Drawing from the Mastectomy Reconstruction Outcomes Consortium (MROC) dataset, a prospective cohort study that involved 11 leading medical centers in the US and Canada, we compared patient-reported outcomes (PROs) assessed utilizing the BREAST-Q, a condition-specific, validated patient-reported outcome measure (PROM) for mastectomy reconstruction, as well as complications between a cohort of patients with Stage IV disease undergoing reconstruction and a control group of women with Stage I-III disease also receiving reconstruction.

The first patients treated with MR-CBCT soft-tissue matching in a MR-only prostate radiotherapy pathway.

Introduction: Magnetic Resonance (MR)-only radiotherapy for prostate cancer has previously been reported using fiducial markers for on-treatment verification. MR-Cone Beam Computed Tomography (CBCT) soft-tissue matching does not require invasive fiducial markers and enables MR-only treatments to other pelvic cancers. This study evaluated the first clinical implementation of MR-only prostate radiotherapy using MR-CBCT soft-tissue matching.
