Background/Objectives: Anxiety before ophthalmic surgery under local anesthesia may hinder patient cooperation and surgical outcomes. Nurse-led auditory interventions offer a promising non-pharmacological approach to perioperative anxiety management. This study evaluated the effectiveness of superimposed binaural beats (SBBs)—classical music layered with frequency differentials—in reducing anxiety during pterygium surgery with conjunctival autografting. Methods: In this randomized controlled trial, 111 adult patients scheduled for elective pterygium excision with conjunctival autografting under local anesthesia were allocated to one of three groups: SBBs, plain music (PM), or silence (control). A trained perioperative nurse administered all auditory interventions. The patients’ anxiety was assessed using the State–Trait Anxiety Inventory—State (STAI-S), and physiological parameters (blood pressure, heart rate, respiratory rate, and oxygen saturation) were recorded before and after surgery. Results: The SBB group showed significantly greater reductions in their STAI-S scores (p < 0.001), systolic blood pressure (p = 0.011), heart rate (p = 0.003), and respiratory rate (p = 0.009) compared to the PM and control groups. No adverse events occurred. Conclusions: SBBs are a safe, nurse-delivered auditory intervention that significantly reduces perioperative anxiety and supports physiological stability. Their integration into routine nursing care for minor ophthalmic surgeries is both feasible and beneficial. Trial Registration: This study was registered with the Thai Clinical Trials Registry (TCTR) under registration number TCTR20250125002 on 25 January 2025. Full article

Background: Since the election of Hamas in 2006, Gaza has endured eight major military conflicts, culminating in the ongoing 2023–2025 war, now surpassing 520 days. This protracted violence, compounded by a 17-year blockade, has resulted in the near-total collapse of Gaza’s health system. Over 49,000 deaths, widespread displacement, and the destruction of more than 60% of health infrastructure have overwhelmed both local capacity and international humanitarian response. Objectives: This narrative review aims to examine and synthesize the current literature (October 2023–April 2025) on the health crisis in Gaza, with a specific focus on identifying key themes and knowledge gaps relevant to rebuilding a sustainable health system. The review also seeks to outline strategic pathways for recovery in the context of ongoing conflict and systemic deprivation. Methods: Given the urgency and limitations of empirical data from conflict zones, a narrative review approach was adopted. Fifty-two sources—including peer-reviewed articles, editorials, reports, and correspondence—were selected through targeted searches using Medline and Google Scholar. The analysis was framed within a public health and political economy perspective, also taking health system building blocks into consideration. Results: The reviewed literature emphasizes emergency needs: trauma care, infectious disease control, and supply chain restoration. Innovations such as mobile clinics and telemedicine offer interim solutions. Gaps include limited attention to mental health (including that of health workers), local governance, and sustainable planning frameworks. Conclusions: Sustainable reconstruction requires a durable ceasefire; international stewardship aligned with local ownership; and a phased, equity-driven strategy emphasizing primary care, mental health, trauma management, and community engagement.

Objectives: This multicenter study aimed to clarify the recurrence patterns; treatment outcomes; and prognostic factors of thymic carcinoma, a rare cancer. Methods: We analyzed 101 patients with thymic carcinoma who underwent multidisciplinary treatment, including radiotherapy. The median age was 62 years, with 27 patients in stage I–II; 44 in stage III; and 30 in stage IV by the TNM classification. Seventy-two patients underwent surgery with radiotherapy; and 29 patients underwent definitive radiotherapy. Image-guided radiotherapy (IGRT) and elective nodal irradiation (ENI) were used for 35 and 23 patients, respectively. Local recurrence-free survival (LRFS); progression-free survival (PFS); and overall survival (OS) were calculated, and univariate and multivariate analyses were performed. Results: With a median follow-up of 68 months, we observed 17 local recurrences; 27 regional recurrences; and 35 distant metastases. The 5-year LRFS; PFS; and OS were 82%, 41%, and 76%, respectively. Multivariate analysis revealed that stage was the only factor associated with LRFS; PFS; and OS (p = 0.040; p < 0.0001; and p = 0.048, respectively), while treatment modality was associated with only LRFS (p = 0.015). IGRT and ENI were also associated with LRFS (p = 0.002 and 0.013, respectively). PFS and OS of stage IV patients were comparable between the surgery with radiotherapy and definitive radiotherapy groups (p = 0.99 and 0.98, respectively). Conclusions: Our results suggest the importance of stage-specific treatment strategies rather than resectability, especially for stage IV patients. These results should be validated in a prospective study. Our results also suggest that radiotherapy methods influence recurrence Full article

This study examines the distinctive male leadership—comprising procurators, parish priests, and chaplains—of the beguinage of St. Elizabeth in Valenciennes during the thirteenth and fourteenth centuries. Contrary to the majority of beguine communities in the southern Low Countries, where leadership appointments were dictated by religious or secular authorities, this community was entitled to elect its male administrators autonomously. The elected were generally influential figures in local religious and secular affairs and maintained a close relationship with the comital family of Hainaut. The analysis will demonstrate how this politically embedded ecclesiastical framework not only ensured doctrinal legitimacy but also mediated conflicts between secular lords and church authorities, thus enabling the community’s survival amid accusations of heresy and institutional repression. By examining the electoral criteria and functional specialization of male leaders, and their interactions with self-governed beguines, this research tries to offer a new perspective on the complex governance strategies of the medieval beguine movement.

Background: Systemic inflammatory markers have emerged as accessible and reproducible tools for oncologic risk stratification, yet their prognostic value in rectal cancer remains incompletely defined, particularly in acute surgical settings. This study aimed to assess six inflammation-based indices—NLR, PLR, MLR, SII, SIRI, and AISI—in relation to tumor stage, recurrence, and outcomes among patients undergoing emergency versus elective resection for rectal cancer. Methods: We retrospectively evaluated 174 patients treated between 2018 and 2024. Pre-treatment blood counts were used to calculate inflammatory indices. Clinical and pathological parameters were correlated with biomarker levels using univariate and multivariate analyses. Results: Pre-treatment inflammation markers were significantly elevated in patients requiring emergency surgery (e.g., NLR: 3.34 vs. 2.4, p = 0.001; PLR: 204.1 vs. 137.8, p < 0.001; SII: 1008 vs. 693, p = 0.007), reflecting advanced tumor biology and immune activation. Notably, these patients also had higher rates of stage IV disease (p = 0.029) and permanent stoma (p = 0.002). Post-treatment, recurrence was paradoxically associated with significantly lower levels of SII (p = 0.021), AISI (p = 0.036), and PLR (p = 0.003), suggesting a potential role for immune exhaustion rather than hyperinflammation in early relapse. Conclusions: Inflammatory indices provide valuable insights into both tumor local invasion and host immune status in rectal cancer. Their integration into perioperative assessment could improve prognostication, particularly in emergency presentations. Post-treatment suppression of these markers may identify patients at high risk for recurrence despite initial curative intent. Full article

Background and Objectives. Umbilical hernia is particularly common among patients with liver cirrhosis, affecting about 20% of this group, compared to 3–8.5% in healthy individuals. This increased prevalence is mainly due to weakened abdominal fascia, elevated intra-abdominal pressure, and malnutrition. The rapid progression of umbilical hernias often leads to complications such as skin necrosis, perforation, and strangulation. Historically, patients with liver cirrhosis and complicated umbilical hernia have faced high morbidity and mortality rates. However, recent advancements in perioperative management, especially in controlling ascites, have improved outcomes in elective treatments. Despite these advancements, managing patients with decompensated liver cirrhosis and complicated umbilical hernia in emergency settings remain a significant surgical challenge. Materials and Methods: We conducted a retrospective review of patients treated for complicated umbilical hernia at the University Medical Centre Ljubljana from 2015 to 2024, using prospectively collected data. This analysis involved implementing hernioplasty combined with incisional negative pressure wound therapy (iNPWT) as part of the surgical protocol. The primary endpoint of our study was the rate of local complications, while the secondary endpoints included the rate of systemic complications and 90-day mortality. Results: We treated 28 consecutive patients with complicated umbilical hernia and liver cirrhosis. Local wound complications were observed in three (10.7%) patients. Systemic complications developed in 10 patients (35.7%). The median duration of hospitalization was 8 days (range: 5–29), and no readmissions were recorded within the 30-day period. Two (7.1%) patients died within 90 days. Conclusions: Our experience indicates that iNPWT, when combined with surgical repair, can be safely utilized, yielding outcomes comparable to elective hernia repairs, even in emergency contexts. Further randomized controlled trials are necessary to validate these findings and optimize treatment protocols. Full article

Federated Learning (FL), a key paradigm in privacy-preserving and distributed machine learning (ML), enables collaborative model training across decentralized data sources without requiring raw data exchange. FL enables collaborative model training across decentralized data sources while preserving privacy. However, selecting appropriate clients remains a major challenge, especially in heterogeneous environments with diverse battery levels, privacy needs, and learning capacities. In this work, a centralized reward-based payoff strategy (RBPS) with cooperative intent is proposed for client selection. In RBPS, each client evaluates participation based on locally measured battery level, privacy requirement, and the model’s accuracy in the current round computing a payoff from these factors and electing to participate if the payoff exceeds a predefined threshold. Participating clients then receive the updated global model. By jointly optimizing model accuracy, privacy preservation, and battery-level constraints, RBPS realizes a multi-objective selection mechanism. Under realistic simulations of client heterogeneity, RBPS yields more robust and efficient training compared to existing methods, confirming its suitability for deployment in resource-constrained FL settings. Experimental analysis demonstrates that RBPS offers significant advantages over state-of-the-art (SOA) client selection methods, particularly those relying on a single selection criterion such as accuracy, battery, or privacy alone. These one-dimensional approaches often lead to trade-offs where improvements in one aspect come at the cost of another. In contrast, RBPS leverages client heterogeneity not as a limitation, but as a strategic asset to maintain and balance all critical characteristics simultaneously. Rather than optimizing performance for a single device type or constraint, RBPS benefits from the diversity of heterogeneous clients, enabling improved accuracy, energy preservation, and privacy protection all at once. This is achieved by dynamically adapting the selection strategy to the strengths of different client profiles. Unlike homogeneous environments, where only one capability tends to dominate, RBPS ensures that no key property is sacrificed. RBPS thus aligns more closely with real-world FL deployments, where mixed-device participation is common and balanced optimization is essential. Full article

Background/Objectives: Non-ablative stereotactic body radiation therapy (SBRT) is commonly employed for locally advanced pancreatic cancer (LAPC) using computed tomography-guided radiotherapy (CTgRT) without online adaptive radiation therapy (oART). The safe delivery of ablative SBRT has been demonstrated using stereotactic magnetic resonance-guided online adaptive radiation therapy (SMART). We performed an in silico comparison of non-adapted CTgRT versus SMART to better understand the potential benefit of oART for ablative pancreatic SBRT. Methods: We retrospectively evaluated original and daily adapted SMART plans that were previously delivered for 20 consecutive LAPC cases (120 total plans across all patients) treated on a 0.35 T MR-linac prescribed to 50 Gy (gross disease) and 33 Gy (elective sites) simultaneously in five fractions. Six comparative CTgRT plans for each patient (one original, five daily treatment) were retrospectively generated with the same prescribed dose and planning parameters as the SMART plans assuming no oART availability. The impact of daily anatomic changes on CTgRT and SMART plans without oART was evaluated across each treatment day MRI scan acquired for SMART. Results: Ninety percent of cases involved the pancreatic head. No statistically significant differences were seen between CTgRT and SMART with respect to target coverage. Nearly all (96%) fractions planned on either CT or MRI platforms exceeded at least one GI organ at risk (OAR) constraint without oART. Significant differences favoring SMART over non-adaptive CTgRT were observed for the duodenum V35 Gy ≤ 0.5 cc (34.2 vs. 41.9 Gy, p = 0.0035) and duodenum V40 Gy ≤ 0.03 cc (37 vs. 52.5 Gy, p = 0.0006) constraints. Stomach V40 Gy trended towards significance favoring SMART (37 vs. 40.3 Gy, p = 0.057) while no significant differences were seen. Conclusions: This is the first study that quantifies the frequency and extent of GI OAR constraint violations that would occur during ablative five-fraction SBRT using SMART vs. CTgRT. GI OAR constraint violations are expected for most fractions without oART whereas all constraints can be achieved with oART. As such, these data suggest that oART should be required for ablative five-fraction pancreatic SBRT. Full article

Background/Objectives: Fast-track (FT) protocols have been developed to reduce the surgical burden and enhance recovery, but they still need to be established for carotid endarterectomy (CEA). In this scenario, carotid stenting has gained momentum by answering the need for a less invasive treatment, despite a still debated clinical advantage. We aim to propose a FT protocol for CEA and to analyze its clinical outcomes. Methods: This retrospective, monocentric study enrolled consecutive patients who underwent CEA for asymptomatic carotid stenosis using an FT protocol between January 2016 and December 2024. Patients undergoing CEA for symptomatic carotid stenosis, carotid bypass procedures, and combined interventions were excluded. Our FT protocol comprises same-day hospital admission, exclusive use of local anesthesia, non-invasive assessment of cardiac and neurological status, and selective utilization of cervical drainage. Discharge criteria were goal-directed and included the absence of pain, electrocardiographic abnormalities, hemodynamic instability, neck hematoma, or cranial nerve injury, with a structured plan for rapid readmission if required. Postoperative pain was assessed using the numerical rating scale (NRS), administered to all patients. The perioperative clinical impact of the protocol was evaluated based on complication rates, pain control, length of hospital stay, and early readmission rates. Results: Among 1051 patients who underwent CEA, 853 met the inclusion criteria. General anesthesia was required in 17 cases (2%), while a cervical drain was placed in 83 patients (10%). The eversion technique was employed in 765 cases (90%). Postoperative intensive care unit (ICU) monitoring was necessary for 7 patients (1%). The mean length of hospital stay was 1.17 days. Postoperatively, 17 patients (2%) required surgical revision. Minor stroke occurred in three patients (0.4%), and acute myocardial infarction requiring angioplasty in two patients (0.2%). Inadequate postoperative pain control (NRS > 4) was reported by five patients (0.6%). Hospital readmission was required for one patient due to a neck hematoma. Conclusions: The reported fast-track protocol for elective carotid surgery was associated with a low rate of postoperative complications. These findings support its clinical value and highlight the need for further validation through controlled comparative studies. Furthermore, the implementation of fast-track protocols in carotid surgery should prompt comparative medico-economic research. Full article

Background/Objectives: Stereotactic radiotherapy (SABR) is a recognized standard treatment modality for localized prostate cancer, though data is limited regarding the risk of increased toxicity when including the elective nodes (ENI) for high-risk disease. Placement of a peri-rectal spacer can decrease the risk of toxicity to the rectum when administering high-dose prostate radiotherapy. Herein we present toxicity findings for patients who underwent five-fraction prostate SABR with ENI in a setting with peri-rectal spacing. Methods: Genitourinary (GU) and gastrointestinal (GI) toxicity data was analyzed for patients with ≥12 months of follow-up who were treated with curative-intent five-fraction SABR with ENI. A radiopaque hydrogel spacer was placed for all eligible patients. The primary endpoints were the three-month toxicity, which was measured using CTCAEv5, and quality of life (QoL), which was measured using EPIC 26. Secondary endpoints included intermediate-term GU and GI toxicity between 6 and 12 months. Univariable logistic regression was used to assess associations between baseline patient characteristics and the presence of a peri-rectal hydrogel spacer and GU and GI toxicity. Results: Among the 100 patients treated, 69 had grade group 4/5 disease and 40 had evidence of T3a/3b extension. The ENI dose was 25 Gy/5, and 78.9% of the patients received 40 Gy to the prostate, while the remainder were given 36.25–37.5 Gy. A total of 70% underwent placement of a radiopaque hydrogel spacer. GU toxicities of grades 1, 2, and 3 were reported in 28/22/1% of the patients, respectively, at three months; in 18/11/0% at six months; in 11/9/0% at nine months; and in 5/3/0% at twelve months. GI toxicities of grades 1 and 2 were reported in 14/0% of the patients at three months and 8/1% at six months, with all cases resolving by nine months. MCICs in the urinary incontinence, urinary obstructive, and bowel domains were reported in 5%, 18%, and 4% at three months; by twelve months, these values decreased to 2%, 2%, and 0%, respectively. The presence of a hydrogel spacer resulted in reductions in high and intermediate doses to the rectum and had a significant inverse association with short-term GI toxicity (HR: 0.09, CI: 0.27–0.35, p: 0.0004). Conclusions: In this prospective series, five-fraction SABR including ENI was well tolerated, and the presence of a hydrogel spacer was associated with a lower risk of rectal toxicity. Full article

Background and Clinical Significance: Papillary Fibroelastoma is a benign primary cardiac tumor, commonly located in a valvular position, predominantly on the aortic valve. Case Presentation: We present a 73-year-old male patient with a medical history of chronic lymphatic leukemia, kidney failure, diabetes, and obstructive sleep apnea. In a routinely performed echocardiogram an abnormal structure in the left ventricle was found. The patient presented completely asymptomatically at the time of examination. A cardiac magnetic resonance-scan provided further information about the size and localization of the tumor in the left ventricle, which seemed to be attached to a papillary muscle and was about 1.6 cm in diameter. Due to visible scarring of the myocardia, which was identified in the scan, a cardiac catheter examination was performed. A coronary artery disease was detected with a severe stenosis in three vessels. During an elective bypass-operation, the removal of the structure was performed with an approach through the left atrium, passing the mitral valve using a valve sizer for better exposure. The tumor of 1 cm presented macroscopically with an anemone-like shape. The histopathological examination confirmed the intraoperative assumption of a papillary fibroelastoma, found in an aberrant location. Conclusions: Unexpectedly challenging surgical removals of structures in the left ventricle require innovative techniques with available instruments for better exposure. Full article

Background and Objectives: Extensive research has demonstrated that various approaches to the quadratus lumborum (QL) block offer superior postoperative analgesia compared to the transversus abdominis plane (TAP) block, particularly in reducing opioid consumption. This study aims to compare postoperative analgesia between the blocks in laparoscopic colorectal surgery. Materials and Methods: A retrospective analysis was performed on patients with elective colorectal surgeries who received bilateral US TAP blocks in the supine position or US anterior QL block in the lateral position at the end of the surgery and before extubating, with Ropivacaine 0.25%. Total opioid consumption and time to first intravenous analgesic were noted. Results: Between January 2020 and December 2024, 410 patients underwent elective laparoscopic colorectal oncology surgery under general anesthesia, with peripheral nerve blocks. Of these, we analyzed 116 patients with localized diseases who underwent elective surgeries and who did not require conversion to classical surgery and received either QL or TAP blocks. A total of 62 patients underwent QL block and 54 received TAP block. For the primary outcome, in the QL group, significantly fewer opioids were used than in the TAP group (p < 0.001), and time to first rescue analgesic was prolonged in the QL group at 16 h (IQR 14–18) compared to the TAP group, where the requirement occurred earlier at 8 h (IQR 8–8) postoperatively (p < 0.001). Conclusions: Postoperative bilateral US anterior QL block reduced morphine consumption and improved time to rescue analgesia and LOS compared with midaxillary line bilateral US TAP block.

Background: Extramammary Paget’s disease (EMPD) is a rare cutaneous carcinoma that typically affects the elderly and is frequently observed in genital and perianal regions. We analyzed the outcomes and prognostic factors for EMPD after radiation therapy (RT). Methods: We analyzed data from 81 patients with non-metastatic EMPD who received either RT alone or in combination with surgery and/or chemotherapy. The median radiation dose was 56 Gy in 28 fractions. Local control (LC), progression-free survival (PFS), and overall survival (OS) rates were calculated using the Kaplan–Meier method. Multivariate analyses were performed using the Cox proportional hazards model. Late adverse events were evaluated by NCI-CTCAE version 5.0. Results: The median age was 78 years, and the median follow-up period was 36 months. The three-year LC, PFS, and OS rates were 75%, 52%, and 80%, respectively. Multivariate analyses identified the presence of lymph node (LN) metastasis, the absence of surgery, and the omission of elective nodal irradiation (i.e., local irradiation only) as significant factors for unfavorable LC (p = 0.01, 0.02, and 0.006) and PFS (p = 0.001, 0.04, and 0.03). LN metastasis was also a significant factor for unfavorable OS (p = 0.005). One patient developed grade 2 skin infection, and another developed grade 3 lymphedema; no grade 4 or higher toxicity was observed. Conclusions: The present results revealed prognostic factors for EMPD after RT and suggest that the absence of surgery and omission of elective nodal irradiation worsened outcomes. A prospective study is needed to establish an optimal treatment strategy for this rare malignancy, which is common in the elderly. Full article

The Samoan general election of 2021 provoked an unprecedented constitutional crisis. It represented yet one more symptom in a shaking of the foundations—not just in politics but within the very nature of Samoan society. The nation’s past stability had resided in the cultural virtue of respect, which permeated its key pillars—the church, law and fa’a Samoa (the customary Samoan way of life). There had been several tremors prior to the election. These had involved court cases involving the church where the Congregational Christian Church Samoa was shown to be in the wrong. These tremors and the more substantial shaking brought about by the constitutional crisis pose several awkward questions as regards the way in which the Christian faith and the Samoan cultural way of life–fa’a Samoa—are commonly regarded as more than complimentary. They also call into question the church’s default practice of silence in the face of public issues. Is it now time to nurture and encourage the public role of the faifeau (minister) for the sake of the common good in a time of significant change? In the absence of a prophetic theology, the tremors and shaking of the foundations signify the necessity of taking some further steps in the development of a local public theology. Full article

Background/Objectives: To evaluate the role of postoperative radiotherapy (PORT) in the management of localized head and neck mucosal melanoma (HNMM). Methods: We retrospectively reviewed 33 patients who underwent surgery for localized HNMM between 2006 and 2023. PORT was delivered to affected anatomical structures, and elective nodal irradiation was not performed. Treatment outcomes, including local recurrence-free survival (LRFS), progression-free survival (PFS), and overall survival (OS), were analyzed. Results: After surgery, 14 patients (41.4%) received PORT. During follow-up, 87.9% of patients experienced recurrence, with local and distant failures being the most common. PORT significantly improved LRFS (p = 0.047) but did not impact PFS or OS. PORT (HR 0.14, p = 0.005) and resection margin status (HR 8.71, p < 0.001) were significantly associated with LRFS in multivariable analysis. Conclusions: PORT for localized HNMM improved local control. Regional recurrence was rare (one patient, 3.4%) even though ENI was not performed. PORT without ENI could improve clinical outcomes for localized HNMM. Full article
