Background: Postoperative fluid-related complications, such as hematoma and seroma formation, are common concerns in breast surgery, adversely affecting surgical outcomes and patient recovery. Topical tranexamic acid (TXA) has emerged as a promising intervention to minimize bleeding while reducing systemic adverse effects linked to intravenous administration. However, evidence on the efficacy of topical TXA in breast surgery remains sparse. Methods: This systematic review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. English-language databases were searched through April 2024 to identify randomized controlled trials and cohort studies assessing the effects of topical TXA on postoperative outcomes in breast surgery, including hematoma, seroma, infection rates, and drain output/duration. Results: Six studies, encompassing 823 patients and 1477 breasts, were included. Subgroup meta-analysis demonstrated a statistically significant reduction in hematoma rates in patients who underwent mastectomy (risk ratio [RR] = 0.14; 95% confidence interval [CI], 0.03–0.78; P = 0.02), but not in patients who underwent breast reduction (RR = 0.76; 95% CI, 0.08–7.08; P = 0.24). No significant differences were found in overall hematoma rates (RR = 0.32; 95% CI, 0.08–1.195; P = 0.09), seroma formation (RR = 1.22; 95% CI, 0.99–1.51; P = 0.07), or infection rates (RR = 0.85; 95% CI, 0.46–1.56; P = 0.59). Conclusions: Topical TXA significantly reduced hematoma rates in patients who underwent mastectomy but showed no significant effect on other outcomes. Larger studies with standardized methodologies are required to fully establish the role of topical TXA in optimizing breast surgery outcomes.

Background and Objective Rehabilitation therapy plays an important role in treating physical and functional impairments observed in individuals undergoing hematopoietic stem cell transplants (HSCT). This study assessed the rehabilitation practices implemented in the HSCT population internationally. Materials and Methods A 48-question online survey comprising questions soliciting information regarding patient characteristics, therapy details (timing, indication, and administering providers), outcome measures, and precautions were developed by an international group of cancer rehabilitation physicians. As reported by European registries, surveys were administered to personnel providing care to patients receiving HSCT at cancer centers, which comprised the top 10% of HSCT volume. In addition, emails were sent to National Medical Societies and registries in the Latin America, Asia, and Pacific regions. Results Forty-three institutions from 18 countries responded to the survey. Half of the centers provided referrals for rehabilitation therapy at the time of admission. Referrals were provided for functional decline (84.5%), risk of falls (53.3%), and discharge planning (42.2%). Rehabilitation therapies were administered by physical therapists (93.0%), occupational therapists (34.9%), therapy aides (14.0%), and speech-language pathologists (11.6%). Approximately 95% of the surveyed centers used objective functional measures such as sit-to-stand (46.5%), grip strength (46.5%), and 6-min walk/gait speed (both 34.9%). The blood counts were monitored to determine the appropriateness of the therapy modalities. Conclusion Rehabilitation practices varied internationally; however, most centers provided skilled therapy during hospitalization for HSCT, utilized objective and patient-reported outcomes, and monitored blood counts to determine the safety of administering therapy.

Introduction Chimeric antigen receptor T-cell therapy (CART) has revolutionized the treatment algorithm of relapsed/refractory (R/R) B-cell non-Hodgkin lymphoma (NHL). However, approximately only 40% of cases achieve long-term durable remissions. Prognostication remains important as it would allow more precise prediction of outcomes and develop a personalized treatment approach. Currently, it is unclear whether prognostic factors that have been predictive of outcomes in the pre-CART era, remain important in the current era. We conducted a single center observational study to assess the prognostic significance of extra nodal involvement (ENI) on long-term outcomes following CART in B-cell NHL. Methods The primary aim was to evaluate the prognostic significance of ENI on long-term outcomes in patients with B-cell NHL treated with CART. The second aim was to specifically evaluate the impact of gastrointestinal (GI) involvement. Continuous variables were summarized as median (range) and categorical variables were reported as frequency (percentage). Kaplan-Meier method was used to estimate freedom from events at different time points and draw corresponding survival curves. Log-rank test was used to compare freedom from events between histology groups. Results 74 patients were included in this analysis, with a median age of 62 (18-85) years. Fifty-three (72%) had evidence of ENI. Twenty-four (47%) had GI involvement as the sole site of ENI or with other sites of ENI. Forty-three (58%) patients were male and diffuse large B-cell lymphoma (DLBCL) was the most common histology (n=50 [54%]) followed by transformed follicular lymphoma (n=20 [27%]). Most patients had advanced stage disease at time of CART (n=71 [96%]) and 3 (4%) had CNS involvement at any time prior to CART. Median number of prior lines of systemic treatment were 2 (1-7) and 64 (87%) had progressive disease at time of CART. Axicabtagene ciloleucel was the most used CART product (n=68 [92%]); Grade 3-4 cytokine release syndrome was reported in 6 (8%) patients and grade 3-4 immune effector cell associated neurotoxicity syndrome was reported in 13 (18%) patients. ICU level of care was needed in 22 (30%) patients and 2 patients (3%) developed hemophagocytic lymphohistiocytosis-like syndrome. Sixty patients (87%) achieved an objective response and 34(49%) achieved a complete response. The 1-year OS was 66% (53-81) in patients who had ENI vs. 72% (54-97) in those without ENI (p=0.82); 1-year relapse rates were at 39% (20-54) vs. 36% (10-54) (p=0.95) for patients with ENI vs. those without ENI. No difference was noted between the two groups regarding progression-free survival and non-relapse mortality (NRM). No difference in outcomes was observed when patients who had GI involvement as the only site of ENI or in combination with other sites of ENI were compared to those who did not have GI involvement as one of the sites of ENI. Elevated LDH at the time of CART (HR 2.27 [95% CI 1.05-4.94], p=0.03), development of any grade ICANS (HR 2.77 [95% CI 1.27-6.04], p=0.01) and requirement for ICU level of care (HR 3.25 [95% CI 1.54-6.86], p=0.002) adversely affected OS; the impact of elevated LDH on OS remained significant in multivariate models (HR 2.34 [95% CI 1.05-5.27], p=0.04). Development of any grade CRS was associated with a decreased risk of relapse (HR 0.25 [95% CI 0.11-0.56], p=<0.001) and the requirement of ICU stay adversely affected NRM (HR 2.27 [95% CI 1.05-4.94], p=0.032). Conclusion These results suggest that ENI does not appear to be predictive of long-term outcomes in the setting of CART therapy. Patients who had ENI appeared to derive equal benefit from CART therapy. GI involvement as a site of ENI has been known to be associated with worse survival when compared to other sites of ENI but we did not observe any difference in this subgroup also. Evolving predictive models and/or biomarkers that take in account the dynamics of the interaction between the malignant and CART cells might help better inform prognostication in the current era.

Abstract Up to 80% of the world's population with epilepsy lives in low and middle‐income countries. Around one‐third of these patients will have drug‐resistant epilepsy, for which epilepsy surgery is an option. Unfortunately, many of these regions, as well as some more developed nations, lack sufficient epilepsy surgery units and trained neurosurgeons. With this in mind, the International League Against Epilepsy (ILAE) formed the Epilepsy Surgery Education Taskforce to address the shortage of further educational opportunities for surgeons and neurologists and to promote the creation of more epilepsy surgery units around the world. In this article, we publish our findings from a web‐based international survey, in which we investigated the global distribution and experience of neurosurgeons who perform epilepsy surgery, their educational paths, and opinions on the further need for epilepsy surgery education, as well as the resources available to them. We report a detailed analysis of the 202 survey replies received from 35 different countries across six continents. The lack of adequate numbers of epilepsy surgery units in the Southern Hemisphere is notable, and the aim of this task force with other ILAE committees, is to improve access to epilepsy surgery for patients and to enhance training for their health care providers.

Abstract Background and Objectives Gastric varices (GVs) are associated with a higher risk of uncontrolled bleeding and death when compared with esophageal varices. While endoscopic glue injection therapy has been traditionally used for secondary prophylaxis in GV, data regarding primary prophylaxis continue to emerge. Recently, EUS–guided therapies have been used in GV bleeding. Methods We conducted a comprehensive search of several major databases from inception to June 2022. Our primary goals were to estimate the pooled rates of treatment efficacy, GV obliteration, GV recurrence, and rebleeding with EUS-guided therapy in primary and secondary prophylaxis. Overall adverse events and technical failures were assessed. Random-effects model was used for our meta-analysis, and heterogeneity was assessed using the I 2 % statistics. Results Eighteen studies with 604 patients were included. In primary prophylaxis, pooled rate of GV obliteration was 90.2% (confidence interval [CI], 81.1–95.2; I 2 = 0). With combination EUS–glue and coil therapy, the rate was 95.4% (CI, 86.7%–98.5%; I 2 = 0). Pooled rate of posttherapy GV bleeding was 4.9% (CI, 1.8%–12.4%; I 2 = 0). In secondary prophylaxis, pooled rate of treatment efficacy was 91.9% (CI, 86.8%–95.2%; I 2 = 12). With EUS-glue, EUS-coil, and combination EUS–glue and coil, the rates were 94.3% (CI, 88.9%–97.1%; I 2 = 0), 95.5% (CI, 80.3%–99.1%; I 2 = 0), and 88.7% (CI, 76%–95.1%; I 2 = 14), respectively. Pooled rate of GV obliteration was 83.6% (CI, 71.5%–91.2%; I 2 = 74). With EUS-glue, EUS-coil, and combination EUS–glue and coil, the rates were 84.6% (CI, 75.9%–90.6%; I 2 = 31), 92.3% (CI, 81.1%–97.1%; I 2 = 0), and 84.5% (CI, 50.8%–96.7%; I 2 = 75), respectively. Pooled rates of GV rebleeding and recurrence were 18.1% (CI, 13.1%–24.3%; I 2 = 16) and 20.6% (CI, 9.3%–39.5%; I 2 = 66), respectively. Conclusion Our analysis shows that EUS-guided therapy for GVs is technically feasible and clinically successful in both primary and secondary prophylaxis of GV.

4591 Background: EV-302 and CheckMate 901 demonstrated significant survival benefit with enfortumab vedotin-pembrolizumab (EVPembro) and gemcitabine-cisplatin-nivolumab (GemCisNivo) as 1L therapy, respectively, in patients (pts) with la/mUC. However, whether these treatments are cost-effective or not remains unclear. Methods: A three-state Markov model (progression-free, progression and death) was developed. State utilities were derived from published literature. State transition probabilities were informed from point-probabilities and hazard ratios for OS and PFS obtained from the latest follow-up of eligible trials. Average sales price (2024 USD) for individual treatments (excluding ancillary charges) were obtained from the center of medicare and medicaid services (US payer’s perspective). Treatment strategies were modeled in accordance with the dose/schedule reported in the eligible trials. Pts who received GemCis or Gem-carboplatin (GemCarbo) and did not progress were modeled to receive Avelumab maintenance. Half-cycle corrected costs and utilities were accrued over a 10-year lifetime horizon and were discounted at 3%. Monte Carlo simulation was used to estimate quality adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs). A willingness-to-pay threshold (WTP) of 100,000$ per QALY was used. Results: In cisplatin-eligible pts, GemCisNivo demonstrated a 0.8 QALY gain over GemCis at an ICER of 21,127 ($/QALY). GemCisNivo was also associated with an incremental net monetary benefit (INMB) of 63,099$ relative to GemCis. EVPembro demonstrated a 2.4 QALY gain over GemCis at an ICER of 915,283 and a 1.6 QALY gain over GemCisNivo at an ICER of 1,406,308. In cisplatin-ineligible pts, EVPembro demonstrated a 2.4 QALY gain over Gem-carboplatin (GemCarbo) at an ICER of 934,761. Price threshold analyses demonstrated that EVPembro is likely to be cost-effective at a cost of 12,344$ for cisplatin-eligible and 13,374$ per cycle for cisplatin-ineligible pts (original cost: 35,665.60$ per cycle). Sensitivity analysis using a total of 12 cycles for EVPembro showed cost-effectiveness at an ICER of 69,594 relative to GemCisNivo in cisplatin-eligible pts, and at an ICER of 53,099 relative to GemCarbo in cisplatin-ineligible pts. Conclusions: In terms of US payer’s perspective, GemCisNivo is most likely to be cost-effective in cisplatin-eligible pts at the WTP of 100,000 $/QALY. Limiting the number of cycles for EVPembro may render it as a cost-effective 1L treatment in la/mUC pts regardless of cisplatin-eligibility status.

Abstract Objective The presence of comorbidities can substantially affect patients’ quality of life, but data regarding their impact on idiopathic inflammatory myopathies (IIMs) are limited. Methods We examined the prevalence of comorbidities in IIM patients, other autoimmune rheumatic diseases (oAIRDs) and healthy controls (HCs), using data from the self-reported COVAD-2 survey. We defined basic multimorbidity (BM) as the presence of ≥2 non-rheumatic chronic conditions and complex multimorbidity (CM) as the presence of ≥3 non-rheumatic chronic conditions affecting ≥3 organ systems. Hierarchical clustering on principal components was performed for grouping. Results Among the COVAD respondents, 1558 IIMs, 4591 oAIRDs and 3652 HCs were analysed. IIMs exhibited a high burden of comorbidities (odds ratio [OR]: 1.62 vs oAIRDs and 2.95 vs HCs, P < 0.01), BM (OR: 1.66 vs oAIRDs and 3.52 vs HCs, P < 0.01), CM (OR: 1.69 vs AIRDs and 6.23 vs HCs, P < 0.01) and mental health disorders (MHDs) (OR: 1.33 vs oAIRDs and 2.63 vs HCs, P < 0.01). Among the IIM patients, those with comorbidities or MHDs had lower PROMIS Global Physical (PGP), PROMIS Global Mental (PGM), and PROMIS Physical Function (SF10) scores, and higher fatigue (F4a) scores (all P < 0.001). PGP, PGM, SF10a and F4a were influenced by age, active disease, BM and MHDs. Four distinct clusters were identified among the IIMs according to comorbidities and PROMIS scores. Conclusion Patients with IIMs have a higher burden of comorbidities that influence physical and mental health, identifiable as clinical clusters for optimized and holistic management approaches.

Summary Introduction Obesity is characterized by chronic low‐grade inflammation. This study presents an updated systematic review and meta‐analysis on the effect of caloric restriction (CR) and intermittent fasting (IF) on plasma inflammatory biomarkers (C‐reactive protein [CRP], tumor necrosis factor [TNF]‐alpha, and interleukin [IL]‐6) in individuals with obesity/overweight compared with unrestricted or ad libitum feeding. Methods PubMed, Web of Science, and SCOPUS databases were searched for randomized controlled trials (RCTs) reporting inflammatory biomarkers after at least 8 weeks of intervention. Standardized mean differences (SMDs) were calculated using a fixed effect model. Heterogeneity was determined using I 2 statistics. Sensitivity analysis was conducted using the “leave‐one‐out” approach. Results Relatively few RCTs have investigated the effect of IF on inflammatory biomarkers than with CR (6 vs. 15). Analysis of pooled data showed that CR was associated with a significant reduction in CRP with low heterogeneity (SMD −0.15 mg/L [95% CI −0.30 to −0.00], p = 0.04; I 2 = 0%, p = 0.69) and IL‐6 with high heterogeneity (SMD −0.31 pg/mL [95% CI −0.51 to −0.10], p = 0.004; I 2 = 73%, p = 0.001). IF was associated with a significant decrease in TNF‐alpha with moderate heterogeneity (SMD −0.32 pg/mL [95% CI −0.63 to −0.02], p = 0.04; I 2 = 44%, p = 0.13). No associations were detected between IF and CRP or IL‐6 and CR and TNF‐alpha. Conclusion CR may be more effective in reducing chronic low‐grade inflammation than IF. However, there were some concerns regarding the included studies' randomization and allocation sequence concealment process.
