The American Venous Forum has formulated evidence-based clinical practice guidelines to provide recommendations on the care of patients with upper extremity deep vein thrombosis. All recommendations follow a systematic review of workup and therapy options for patients with upper extremity deep vein thrombosis. Potential limitations of these guidelines are due to the lack of evidence on some specific sub-areas such as risk stratification and long-term outcomes.

INTRODUCTION/BACKGROUND:Hounsfield units (HU) are a validated marker of bone mineral density. This study aimed to determine whether low-energy Schatzker IV, V and VI tibial plateau fractures are associated with altered bone quality. METHODS:). Fractures were classified by injury mechanism (low- vs. high-energy) and HU thresholds were defined as poor (< 110) or normal (> 160). Clinical outcomes included major complications, reoperations, range of motion, Visual Analog Scale (VAS) pain scores, and Short Musculoskeletal Function Assessment (SMFA) scores. RESULTS:Low-energy fractures (n = 96) had significantly lower HU values (113.9 vs. 150.9, p < 0.0001) across all planes. No significant differences were found in clinical outcomes. CONCLUSION/CONCLUSIONS:Low-energy Schatzker IV-VI fractures indicate poor bone quality and may represent "fragility fractures" requiring further evaluation.

BACKGROUND:Motivational text messages can encourage increased physical activity. This study aimed to validate motivational text messages among older adults and care partners and to assess differences in perceived motivational value between the two groups. METHODS:We designed nine motivational text messages to capture nine distinct physical activity scenarios. For this cross-sectional observational study, we enrolled 14 content experts, 310 older adults, and 305 care partners. Content experts assessed the relevance, while the older adults and care partners assessed the perceived motivational value of each text message on a 5-point Likert scale. We computed the item content validity index and assessed differences in perceived motivational value among older adults and care partners using quantile regression while adjusting for sociodemographic and health characteristics. RESULTS:The item content validity index ranged from 0.86 to 1.00. The median (interquartile range) perceived motivational value for each text message was 4.0 (3.0-5.0), and there were no statistically significant differences in reported motivational values between older adults and care partners. CONCLUSION/CONCLUSIONS:We present nine content-validated text messages with high motivational value for older adults and care partners that can be integrated into technology-based intervention studies and may improve physical activity behavior in both groups.

Breast cancer disparities in outcomes remain a persistent challenge in the USA, with survival influenced by neighborhood context, access to resources, and the applicability of existing scientific evidence across populations. These disparities arise from complex, intersectional factors spanning social, structural, and biologic domains. While social determinants of health (SDOH) are strongly associated with breast cancer incidence and outcomes, the causality of biologic mechanisms underlying these associations remain incompletely understood. This review examines breast cancer disparities at the societal level and highlights emerging research that links social epidemiology with tumor biology, emphasizing the need for continued investigation using advanced genomic and epigenetic approaches to better understand and ultimately reduce inequities in breast cancer outcomes.

Heart failure (HF) and chronic kidney disease (CKD) frequently coexist, which elevates the risks of hospitalization, disease progression, and death. Despite advances in treating each condition independently, many challenges remain in diagnosing and managing them in combination. In March 2024, Kidney Disease: Improving Global Outcomes (KDIGO) held the Controversies Conference on Kidney Disease and Heart Failure: Recent Advances and Current Challenges. Discussions highlighted the complex, bidirectional relationship between HF and CKD, including shared risk factors and overlapping pathophysiology as well as nuances in interpreting biomarkers such as natriuretic peptides and serum creatinine. Sodium-glucose cotransporter-2 inhibitors, renin-angiotensin-aldosterone system inhibitors, and emerging agents such as finerenone and glucagon-like peptide-1 receptor agonists can have benefits in both populations of patients with HF and CKD, though evidence in advanced CKD remains limited. Importantly, small declines in kidney function after initiating guideline-directed HF therapies generally do not require discontinuation, as these declines are often hemodynamic in nature and not associated with poor outcomes. The group highlighted the need for CKD-specific HF diagnostic thresholds and refined acute kidney injury definitions in HF. It is important for future cardiovascular and kidney trials to include relevant end points, such as kidney function trajectories, symptom burden, and quality of life. To improve care for individuals with HF and CKD, a more integrated approach to management, rooted in individualization, clinical context, and shared therapeutic goals, is needed.

INTRODUCTION/BACKGROUND:Postoperative urinary retention (POUR) is a common complication following inguinal hernia repair (IHR), and it can be influenced by the type of neuromuscular blockade reversal medication used, especially acetylcholinesterase inhibitors. Among the available options for neuromuscular blockade reversal, Sugammadex has gained significant popularity due to its effectiveness, speed, and safety profile. Additionally, some studies suggest that it prevents POUR compared to acetylcholinesterase inhibitors. We aimed to perform a systematic review and meta-analysis to assess the POUR rates with the use of Sugammadex after IHR. METHODS:PubMed, EMBASE, Cochrane, LILACS, and Web of Science databases were systematically searched without date or language restrictions from inception to October 2024. The databases were searched for studies comparing Sugammadex with other medications for neuromuscular blockade reversal after IHR. The primary outcome was POUR. RESULTS:< .001), with a relative risk reduction of 89%. CONCLUSION/CONCLUSIONS:Sugammadex is associated with a significantly lower risk of POUR following IHR when compared to other medications for neuromuscular blockade reversal following IHR. Despite its higher cost and decreased availability in some centers, the use of Sugammadex should be strongly considered as the preferred option to prevent POUR and minimize the need for hospital readmissions.

BACKGROUND/UNASSIGNED:The Standard of Care (SOC) for treating significant spinal epidural abscesses (SEA) is STAT surgery for patients with the new-onset of neurological deficits following STAT contrast MR studies confirming significant neural (i.e. mild/moderate, moderate, or marked cord/nerve root) compression. Too many health care professionals, including physicians, and select spine surgeons still wrongly believe delaying "acute" spinal decompressions in patients with SEA for up to 8, 12, and even 24 hours is acceptable even in paralyzed patients. METHODS/UNASSIGNED:Here we review the fact that the standard of care for treating SEA is STAT surgery for patients demonstrating the new-onset of neurological deficits following STAT contrast MR scans confirming significant neural compression. RESULTS/UNASSIGNED:STAT surgery for newly neurologically symptomatic patients with SEA following STAT contrast MR scans documenting significant neural compression yields the best results. Notably, select patients without neural deficits or significant MR neural compression may be considered for non-surgical treatment. The "gold standard" for diagnosing SEA is the contrast MR, while non-contrast CT studies almost uniformly fail to diagnose SEA, and Myelogram-CT studies have significant limitations (i.e. risk of causing meningitis, and may fail to document cephalad extent of SEA if there is a distal total block to intrathecal contrast). CONCLUSION/UNASSIGNED:STAT surgery is the SOC and treatment of choice for patient with SEA demonstrating significant new-onset neurological deficits with significant STAT contrast MR findings of neural compression. Further, STAT means STAT, no waiting period is acceptable (i.e. 8, 12 or up to < 24 hours) particularly in paralyzed patients.
