Alkaline phosphatase decline and pain response as predictors of overall survival benefit in patients treated with radium-223: a post hoc analysis of the REASSURE study.

Background: Alkaline phosphatase (ALP) declines and pain responses can occur during radium-223 (Ra) treatment, but their association with treatment outcomes is unclear.

Methods: For patients with metastatic castration-resistant prostate cancer treated with Ra in the REASSURE study, we investigated whether ALP decline (Week 12) and/or pain response (during treatment) are associated with improved overall survival (OS). The Brief Pain Inventory-Short Form (BPI-SF) was used to assess pain at baseline and pain response (in patients with baseline BPI-SF score ≥2).

Hypothalamic deep brain stimulation augments walking after spinal cord injury.

A spinal cord injury (SCI) disrupts the neuronal projections from the brain to the region of the spinal cord that produces walking, leading to various degrees of paralysis. Here, we aimed to identify brain regions that steer the recovery of walking after incomplete SCI and that could be targeted to augment this recovery. To uncover these regions, we constructed a space-time brain-wide atlas of transcriptionally active and spinal cord-projecting neurons underlying the recovery of walking after incomplete SCI.

Altered sphingolipid profile in response to skeletal muscle injury in a mouse model of type 1 diabetes mellitus.

A complication of type 1 diabetes mellitus (T1DM) is diabetic myopathy that includes reduced regenerative capacity of skeletal muscle. Sphingolipids are a diverse family of lipids with roles in skeletal muscle regeneration. Some studies have found changes in sphingolipid species levels in T1DM, however, the effect of T1DM on a sphingolipid panel in regenerating skeletal muscle has not been examined.

The quantitative impact of prostate-specific membrane antigen (PSMA) PET/CT staging in newly diagnosed metastatic prostate cancer and treatment-decision implications.

Objectives: To quantify the stage-shift with prostate-specific membrane antigen (PSMA) PET/CT imaging in metastatic prostate cancer and explore treatment implications.

Methods: Single-centre, retrospective analysis of patients with newly diagnosed [F]PSMA-1007 or [Ga]Ga-PSMA-11 PET/CT-detected metastatic prostate cancer who had baseline bone scintigraphy between January 2015 and May 2021. Patients were subclassified into oligometastatic and polymetastatic disease utilizing the STAMPEDE2 trial (ISRCTN66357938/NCT06320067) definition.

Surgical Castration as an Alternative to Improve Systemic Treatment for Advanced Prostate Cancer: A Window of Opportunity for Developing Countries.

Purpose: The Brazilian Public Health System (BPHS) serves approximately 71,730 patients with prostate cancer (PC) every year for which androgen deprivation therapy (ADT) is the primary treatment for patients with advanced hormone-sensitive prostate cancer (aHSPC). Androgen receptor pathway inhibitors (ARPIs) are not accessible through the BPHS. Using the BPHS as a model, this study assesses the long-term economic effect of surgical versus medical castration in aHSPC treatment to strategize cost reduction and the incorporation of ARPI in developing countries.

Comparison and combination of mutation and methylation-based urine tests for bladder cancer detection.

Background And Aims: Several non-invasive tests for detecting bladder cancer (BC) are commercially available and are based on detecting small panels of BC-associated mutations and/or methylation changes in urine DNA. However, it is not clear which type of biomarker is best, or if a combination of the two is needed. In this study we address this question by taking a 23-gene mutation panel (GALEAS™ Bladder, GB) and testing if adding a panel of methylation markers improves the sensitivity of BC detection.

Image directed redesign of bladder cancer treatment pathways: the BladderPath RCT.

Background: Transurethral resection of bladder tumour has been the mainstay of bladder cancer staging for > 60 years. Staging inaccuracies are commonplace, leading to delayed treatment of muscle-invasive bladder cancer. Multiparametric magnetic resonance imaging offers rapid, accurate and non-invasive staging of muscle-invasive bladder cancer, potentially reducing delays to radical treatment.

The Man Van: A pilot study of using mobile targeted case-finding to address health inequalities in prostate cancer.

Early diagnosis remains a major limitation of cancer outcomes with ethnicity and deprivation being determinants of inequalities that impact outcomes. Prostate cancer suffers from lower incidence rates and higher mortality rates in the most deprived versus the least deprived groups. We developed the 'Man Van' to enable high-risk male patients' from deprived communities and ethnic minorities increased access to health care to address these health inequalities.

Management of Index Finger Metacarpophalangeal Joint Arthritis.

Metacarpophalangeal joint arthritis of the index finger is a debilitating disease often caused by osteoarthritis or inflammatory arthritides such as rheumatoid arthritis. Treatment options include nonsurgical management with nonsteroidal anti-inflammatory drugs, splinting, occupational therapy, corticosteroid injections, and disease-modifying antirheumatic drugs. Operative management options include arthrodesis and arthroplasty, which can be further broken down into silicone implants and 2 component resurfacing implants.

A framework and review of evidence of the importance of coral reefs for marine birds in tropical ecosystems.

As global heating and other anthropogenic influences alter tropical marine environments, it is unclear how marine bird populations will be impacted and whether their current roles in tropical marine ecosystems will change. Although marine birds roost and breed on tropical islands in large numbers, the direct trophic interactions between these birds and their prey across the tropics are poorly documented. We present a first framework for evaluating the dependence on and contributions of marine birds to tropical coral reef ecosystems and use it to examine the evidence for different kinds of interaction, focusing primarily on avian diets.

How Can Participant Experience of Quality-of-Life Research Be Improved in Cancer Research: Views of the Patient and Public Involvement Representatives from the STAMPEDE2 Prostate Cancer Trial.

Enhancement of the participant experience in quality of life (QOL) research is imperative to improve recruitment and ongoing engagement in QOL studies. Implementation of recommendations made by the patient and public involvement representatives for STAMPEDE2 could optimise the impact of QOL studies, with a benefit for participants and collection of invaluable data for cancer care research.

Low-grade Urothelial Carcinoma Recurs at a Tempo that Naturally Accelerates Over Time.

Objective: To investigate the cadence of recurrence in patients with low grade intermediate-risk non-muscle invasive bladder cancer (LG IR-NMIBC) based on clinical determinants. We aim to describe patterns in rates of recurrence to better inform surveillance regimens for this chronic, burdensome, and costly disease.

Methods: Using baseline and follow-up data from participants in the West Midlands' (United Kingdom, UK) Bladder Cancer Prognosis Programme (BCPP), we assessed overall recurrence rate and recurrence-free intervals throughout the follow-up period for IR-NMIBC participants.

Single-cell and spatial atlases of spinal cord injury in the Tabulae Paralytica.

Here, we introduce the Tabulae Paralytica-a compilation of four atlases of spinal cord injury (SCI) comprising a single-nucleus transcriptome atlas of half a million cells, a multiome atlas pairing transcriptomic and epigenomic measurements within the same nuclei, and two spatial transcriptomic atlases of the injured spinal cord spanning four spatial and temporal dimensions. We integrated these atlases into a common framework to dissect the molecular logic that governs the responses to injury within the spinal cord. The Tabulae Paralytica uncovered new biological principles that dictate the consequences of SCI, including conserved and divergent neuronal responses to injury; the priming of specific neuronal subpopulations to upregulate circuit-reorganizing programs after injury; an inverse relationship between neuronal stress responses and the activation of circuit reorganization programs; the necessity of re-establishing a tripartite neuroprotective barrier between immune-privileged and extra-neural environments after SCI and a failure to form this barrier in old mice.

Refining Risk Stratification of High-risk and Locoregional Prostate Cancer: A Pooled Analysis of Randomized Trials.

Background And Objective: Radiotherapy (RT) and long-term androgen deprivation therapy (ltADT; 18-36 mo) is a standard of care in the treatment of high-risk localized/locoregional prostate cancer (HRLPC). We evaluated the outcomes in patients treated with RT + ltADT to identify which patients have poorer prognosis with standard therapy.

Methods: Individual patient data from patients with HRLPC (as defined by any of the following three risk factors [RFs] in the context of cN0 disease-Gleason score ≥8, cT3-4, and prostate-specific antigen [PSA] >20 ng/ml, or cN1 disease) treated with RT and ltADT in randomized controlled trials collated by the Intermediate Clinical Endpoints in Cancer of the Prostate group.

Getting our ducks in a row: The need for data utility comparisons of healthcare systems data for clinical trials.

Background: Better use of healthcare systems data, collected as part of interactions between patients and the healthcare system, could transform planning and conduct of randomised controlled trials. Multiple challenges to widespread use include whether healthcare systems data captures sufficiently well the data traditionally captured on case report forms. "Data Utility Comparison Studies" (DUCkS) assess the utility of healthcare systems data for RCTs by comparison to data collected by the trial.

Trauma Bay Evaluation and Resuscitative Decision-Making.

The reader of this article will now have the ability to reflect on all aspects of high-quality trauma bay care, from resuscitation to diagnosis and leadership to debriefing. Although there is no replacement for experience, both clinically and in a simulation environment, trauma clinicians are encouraged to make use of this article both as a primer at the beginning of a trauma rotation and a reference text to revisit after difficult cases in the trauma bay. Also, periods of reflection seem appropriate in the busy but, of course, rewarding career in trauma care.

The Pitfalls of Difficult Distal Radius Fractures and Provisional Reduction.

Distal radius fractures are some of the most common injuries encountered in orthopedics and require careful consideration when determining the appropriate treatment options. These fractures can be difficult injuries to treat surgically based on a large variability of fracture patterns, bone quality, and anatomy. It is important to understand the potential pitfalls associated with the treatment of difficult distal radius fractures to prevent avoidable complications.
