Background: Health disparities between racial groups continue to exist. There is a paucity of data regarding presentation severity for acute diverticulitis (AD) and surgery need by race. This study’s aim was to evaluate outcomes of AD in United States racial groups. Methods: A retrospective cohort study was performed using the 2016–2019 National Inpatient Sample of adult patients discharged for AD. Patients were classified into six racial and ethnic groups: Caucasian, African American (AA), Hispanic, Asian, Native American (NA), and other. Multivariate regression analysis adjusted for patient and hospital characteristics was performed for primary and secondary outcomes. Results: A total of 647,119 admissions with acute diverticulitis (AD) were identified. Most patients were Caucasian (about three-quarters), followed by Hispanics (11%), AA (9%), Asians (1%), Native Americans (<1%), and other (2%). Minority groups were generally younger than Caucasians and less likely to undergo colonoscopy or surgical procedures such as partial or total colectomy. In the multivariable analysis, both Hispanics and AA were less likely to present with complicated diverticulitis. Despite this, their hospitalizations were associated with higher overall charges and costs. No significant differences were found across groups in terms of inpatient mortality or the need for percutaneous abscess drainage. Conclusions: Hispanic and AA have higher healthcare- related charges and costs compared to Caucasians when admitted with AD. Further studies are needed to understand the healthcare-related spending variations seen in these groups despite them often having less complicated AD.

Background/Goal: Parkinson’s disease (PD) disrupts dopaminergic transmission, leading to motor deficits and altered activity in the primary motor cortex (M1). While M1 modulation is critical for motor control, its response to dopaminergic degeneration and treatment remains unclear. This study aimed to characterize M1 neuronal activity and motor behavior in hemiparkinsonian rats using in vivo calcium imaging across naïve, lesioned, and levodopa-treated states. Methods: Thirteen Sprague Dawley rats were injected with GCaMP6f in the M1 and implanted with a GRIN lens and guide cannula targeting the medial forebrain bundle. Calcium imaging and motor behavior were assessed longitudinally using a single pellet reaching test (SPRT) before and after unilateral 6-hydroxydopamine (6-OHDA) lesioning and subsequent levodopa/carbidopa treatment. Dopaminergic lesion severity was quantified via tyrosine hydroxylase immunohistochemistry. Calcium event frequency and influx were analyzed with CNMF-E and statistical modeling. Results: Levodopa treatment improved fine motor performance as shown by a significant reduction in grasp errors (mean difference: −8.91, 95% CI: −16.66 to −1.16, p = 0.031) and increased reaching duration (mean difference: 4.13, 95% CI: 0.94 to 7.32, p = 0.019) compared to the lesioned state. M1 calcium activity showed modulation dependent on lesion severity: low-lesion rats exhibited reduced event frequency (mean difference: 0.04 Hz, 95% CI: 0.001 to 0.08, p = 0.045) and increased influx post-lesion (mean difference: −0.20 z·s, 95% CI: −0.38 to −0.02, p = 0.038), while high-lesion rats showed increased influx only after levodopa treatment (mean difference: −0.34 z·s, 95% CI: −0.52 to −0.16, p = 0.003). Correlation analyses revealed that calcium influx, but not frequency, was negatively correlated with lesion severity during levodopa treatment (Spearman r = −0.857, p = 0.024). Conclusion: M1 neuronal activity appears to be differentially modulated by dopaminergic degeneration and levodopa treatment in a lesion-dependent manner. These preliminary findings suggest dynamic cortical responses in PD and support the utility of calcium imaging for monitoring circuit-level changes in disease and therapy. Further research with larger cohorts and complementary methodologies will be necessary to validate and extend these observations.

Background: Early detection and prediction of arterial hypertension (HTN) are vital to reduce cardiovascular morbidity and mortality. AI has enhanced ECG diagnostic capabilities, enabling detection of latent cardiovascular abnormalities. Aims: This systematic review evaluates current evidence on AI-enhanced ECG for detection and prediction of HTN in in both clinical and subclinical populations. Methods: A search was conducted on April 28, 2025, in PubMed, Scopus, and Web of Science. Gray literature and study reference lists, plus the first 10 pages of Google Scholar, were screened. The review followed PRISMA 2020 guidelines. Bias risk was assessed using PROBAST (for prediction models) and QUADAS-2 (for diagnostic studies). Two reviewers independently performed study selection and data extraction after pilot training. Results: A total of 26 studies were included: 16 focused on detection and 10 on prediction of HTN using AI-enhanced ECG. Overall, 96% reported successful outcomes, underscoring the strong diagnostic and prognostic potential of this approach. Among detection studies, 94% successfully identified hypertensive individuals, classified blood pressure (BP) levels, or evaluated cardiovascular risk. Most were retrospective in design (75%), with internal validation in 44% and external validation in 19%. Sample sizes ranged from 100 to over 120,000, including healthy and cardiovascular patients. Commonly used algorithms included deep Learning, random forest, and ensemble methods, often using single-lead ECG data, highlighting the feasibility of wearable technologies. QUADAS-2 identified 56% of studies had low risk of bias. All prediction studies achieved accurate estimation of systolic/diastolic BP or predicted future HTN onset. Designs were 40% experimental and 50% retrospective. All studies reported internal validation, and 50% included external validation. AI models such as CNNs, ResNet-LSTM, and U-Net were used across clinical and community-based populations, with follow-up periods of up to 6.8 years. Populations were predominantly normotensive or mixed. PROBAST assessments showed 60% low and 40% moderate risk of bias. Conclusion: AI-enhanced ECG is a promising, non-invasive tool for early detection and prediction of HTN. However, external validation and clinical trials are needed to support integration and generalizability.

The TransMet trial and Norwegian studies have shown excellent outcomes in highly selected patients undergoing liver transplant (LT) for unresectable colorectal liver metastases (uCRLM). Our aim is to provide an updated analysis of the current state of LT for uCRLM in the United States. Adult patients with a diagnosis of uCRLM listed for LT between December 2017 and March 2025 were identified from the United Network for Organ Sharing database and analyzed. An analysis of living donor LT (LDLT) and deceased donor LT (DDLT) was performed. During this period, 222 patients were listed, and 158 received an LT across 33 centers. Of these, 76 (48.1%) underwent LDLT, and 82 patients (51.9%) underwent DDLT. Of the 82 deceased donors, 56 (68.2%) were out-of-sequence offers. Overall, the 3-year survival and disease-free survival rates were 66.7% and 44.0%, respectively. The 3-year survival for LDLT and DDLT was 74.1% and 57.3% ( p =0.04), respectively. While these results have not yet reached the acceptable threshold established for other LT indications, they have improved and are expected to continue improving after the implementation of prioritization points. Given the potential variability of oncologic selection criteria and graft quality, we call for the standardization of nationally accepted selection criteria for listing patients for LT with uCRLM and for providing early access to high-quality organs. To achieve this, it is imperative to create, update, and maintain national databases that allow for the collection of more granular oncological variables.

Abstract Rehabilitation after musculoskeletal trauma is globally acknowledged as essential for restoring function and improving quality of life; however, significant variation exists in rehabilitation frameworks and services worldwide. Although certain principles—such as early intervention, structured care pathways, and multidisciplinary approaches—are universally recognized as important determinants of outcomes in trauma patients, their implementation and effectiveness vary considerably due to differences in health care infrastructure, economic resources, policy frameworks, and cultural contexts. Drawing on comparative analyses of rehabilitation frameworks across regions, including North America, Latin America, Europe, Asia-Pacific, and Africa, this paper identifies structural variations, systemic challenges, and innovations that can inform global rehabilitation efforts. Strategic international collaboration focusing on shared learning, standardized protocols, technology integration, and targeted investments is key to creating equitable and sustainable rehabilitation models, especially in resource-limited settings and aging populations.

The treatment landscape of B-cell lymphomas has significantly evolved in recent years with approval of novel targeted therapies. CD3 × CD20 bispecific antibodies and CD19-directed monoclonal antibodies and antibody–drug conjugates have demonstrated efficacy in relapsed/refractory follicular lymphoma (FL). Bruton tyrosine kinase (BTK) inhibitor–based regimens are emerging as effective treatment options for patients with TP53-mutated classical mantle cell lymphoma (MCL). Results from ongoing clinical trials suggest that the addition of CD3 × CD20 bispecific antibodies to chemoimmunotherapy improves outcomes in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). These NCCN Guideline Insights highlight significant updates to the NCCN Guidelines for B-Cell Lymphomas for the treatment of FL, MCL, and DLBCL.

ABSTRACT Anesthetic technique affects surgical outcomes and oncological prognosis. Recognizing the critical role of surgery in cancer treatment, this narrative review aims to improve anesthesiology practices for cancer patients by evaluating actions that positively influence outcomes. Anesthesiologist experience helps guide technique choice in complex cases. Decisions should be customized based on the type of surgery and patient condition, as different techniques can significantly impact results. The expertise of the entire team at specialized centers further enhances outcomes.

Autologous Chimeric antigen receptor (CAR) T-cell therapies have demonstrated substantial efficacy in patients with relapsed or refractory hematologic malignancies; however, their implementation has been constrained by regulatory barriers. Risk Evaluation and Mitigation Strategies (REMS), mandated by the U.S. Food and Drug Administration (FDA), were initially implemented to mitigate risks associated with cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), and other treatment-related toxicities. On 27 June 2025, the FDA removed REMS requirements for all approved B-cell maturation antigen (BCMA) and CD19-directed autologous CAR T-cell therapies, citing that current product labeling sufficiently communicates safety information. Key regulatory changes include the elimination of site certification and tocilizumab stocking requirements, a reduction in the recommended post-infusion proximity period from four weeks to two weeks, increased flexibility regarding monitoring locations, and a shortened driving restriction from eight weeks to two weeks. This review examines the rationale for the REMS requirements for CAR T-cell therapies, synthesizes contemporary safety data from clinical trials and real-world practice, and explores the implications of this regulatory shift for access to care, particularly in rural and underserved populations. The removal of REMS requirements may facilitate broader implementation of CAR T-cell therapies and alleviate logistical and institutional barriers, offering the potential to expand access while preserving patient safety.

Background: Variable terminology is used in the literature to describe facial synkinesis and hypertonicity following incomplete recovery from facial paralysis and its associated medical and surgical treatments. Study Objectives: Establish a nomenclature consensus for this condition among a group of facial nerve experts. Design Type: Consensus study. Methods: Using modified Delphi methodology, an international, multidisciplinary group of facial nerve experts reviewed the terminology for the name of the clinical condition and treatments of interest. Online surveys and a virtual discussion were performed to establish consensus, defined a priori as agreement by 80% of the group. Results: Twenty-five facial nerve experts established consensus after three Delphi rounds. Consensus terminology for the condition is “facial synkinesis” with 84% agreement. Medical treatment is termed “chemodenervation” with 100% agreement. Surgical treatments including “selective facial neurectomy,” “selective facial neurotomy,” “selective facial myectomy,” and “selective facial myotomy,” were defined and reached agreement of 100%. Conclusions: This international group of facial nerve experts has recommended standardized nomenclature for the condition of facial synkinesis and its various treatments. While “facial synkinesis” reached consensus as the preferred term, some experts noted it may insufficiently describe the full clinical spectrum, which includes muscle hypertonicity, weakness, and spontaneous twitching.
