Objectives: Lesion-level dynamics may reveal pulmonary tuberculosis (PTB) heterogeneity and help identify factors associated with treatment outcomes. Methods: A total of 288 serial Computed Tomography (CT) scans from 125 PTB patients were obtained from the National Institute of Allergy and Infectious Diseases (NIAID) TB Portals database (2008–2023). Lesions were segmented and annotated to obtain volume and imaging features, and a conservative longitudinal volume quantification method was used to characterize dynamic volume patterns. The proportion of lesions with different patterns was analyzed at the patient level to assess trajectory diversity. Firth’s penalized logistic regression was used to identify factors associated with treatment outcomes. Results: Among 435 lesions in 125 patients, five patterns emerged: Stable, Decrease, Increase, Mix-I-D (increase then decrease), and Mix-D-I (decrease then increase). Multiple patterns coexisted in 66.7% of treatment success patients and all treatment failure patients. Mix-D-I lesions were identified more frequently in treatment failure patients (25.0% vs. 1.4%, p = 0.027), and in multivariable analysis, the presence of Mix-D-I lesions was statistically associated with treatment failure (p = 0.024). Conclusions: PTB lesions showed high trajectory heterogeneity. The presence of Mix-D-I lesions may point to an unfavorable treatment course, suggesting lesion dynamics could serve as a potential indicator for poor outcomes. By quantifying lesion-level trajectories on serial CT scans, we extend PET/CT-based evidence and support the value of routine monitoring in clinical management of tuberculosis. Full article

Mining is an economic activity with significant socio-environmental implications, particularly in regions where communities depend directly on natural resources. This study aimed to analyze the perceptions of residents of the Pungala parish regarding the impacts of mining in the Alao River basin. A questionnaire was administered, considering sociodemographic, social, and environmental variables. The surveyed population was predominantly older adults and had a balanced gender distribution. The majority identified as indigenous or mestizo, with primarily secondary school educational levels and with a labor structure characterized by independent work. At the social level, mining is perceived as a source of economic benefits through job creation and increased income. However, negative impacts are also recognized, including conflicts over water use, displacement of families, and increased costs of goods and services. From an environmental perspective, the majority perceived negative changes, particularly water pollution, deforestation, erosion, and biodiversity loss. Regarding the ecosystem services, provisioning services were perceived as having the greatest importance and frequency of use, especially water for human consumption, irrigation, and productive activities. These results demonstrate the coexistence of benefits and risks and highlight the need for sustainable management strategies that integrate ecosystem conservation and community well-being.

Pregnancy (HP), defined as the coexistence of intrauterine and ectopic gestations, is a rare condition, especially in spontaneous conception, but it is a life-threatening obstetric emergency when rupture occurs, with a reported maternal mortality rate of 0.03%. Diagnosis is often delayed because confirmation of an intrauterine pregnancy can mask clinical signs of a concurrent ectopic gestation. Early recognition and prompt surgical intervention are therefore critical to maternal safety and preservation of intrauterine viability. This case highlights the diagnostic challenges and successful management of a spontaneous ruptured heterotopic pregnancy. Case presentation: A 34-year-old Middle Eastern woman, gravida 4, with a spontaneous conception, presented with sudden severe lower abdominal pain and signs of acute hemoperitoneum (hypotension, tachycardia, and marked peritoneal signs). Transvaginal ultrasound demonstrated a viable intrauterine pregnancy at 9 weeks 4 days gestation, together with a ruptured left tubal ectopic pregnancy of similar gestational age. The patient underwent urgent laparoscopic left salpingectomy with evacuation of approximately 1200 mL of intraperitoneal blood and clots. Postoperatively, she developed significant anemia (hemoglobin drop from 11.2 g/dL on admission to 6.5 g/dL) requiring transfusion of four units of packed red blood cells. Serial ultrasonographic follow-up confirmed ongoing viability of the intrauterine pregnancy, which ultimately resulted in a live birth at term. Progressive resolution of the postoperative pelvic hematoma was also noted. Conclusions: Ruptured heterotopic pregnancy remains a diagnostic and therapeutic challenge. This case, along with a synthesis of the contemporary literature, demonstrates that a high clinical index of suspicion, timely ultrasound diagnosis, and immediate minimally invasive surgical management are paramount. Furthermore, rigorous postoperative monitoring and resuscitation, including targeted transfusion, are essential to achieve maternal stabilization while allowing continuation of a viable intrauterine pregnancy, with reported live birth rates exceeding 70% following timely intervention.

This case report highlights the coexistence of two rare coronary artery anomalies assessed by computed coronary tomography angiography (CCTA). We present the case of a 51-year-old hypertensive patient with a type II double left anterior descending artery (LAD) and an anomalous infundibular branch originating from the pulmonary artery (partial ARCAPA). This association may have contributed to a limited ischemic burden, explaining the patient’s asymptomatic state. Knowledge of these rare coronary anatomies is essential for accurate diagnosis and management. Full article

Background: Cerebrovascular accidents (stroke) remain a leading global cause of death and disability, with its burden increasingly overlapping the rising prevalence of obstructive sleep apnea (OSA) and diabetes mellitus (DM). These highly prevalent cardiometabolic conditions frequently coexist and may jointly amplify cerebrovascular risk through shared and interacting pathophysiologic pathways. This narrative review synthesizes current evidence on the independent and combined contributions of OSA and DM to cerebrovascular complications, with emphasis on mechanisms, stroke outcomes and implications for screening and integrated management. Methods: A narrative review was conducted using PubMed, MEDLINE, and the Cochrane Library to identify English-language articles published between January 2000 and December 2024. Search terms combined OSA or sleep-disordered breathing with stroke or cerebrovascular disease and DM or hyperglycemia. Secondary searches targeted mechanistic domains including intermittent hypoxia, insulin resistance, metabolic syndrome, atrial fibrillation, hypercoagulability, and bariatric surgery. Priority was given to systematic reviews and meta-analyses, randomized controlled trials, and large prospective cohort studies, with smaller studies included when mechanistically informative. Findings were synthesized thematically across OSA-related mechanisms, DM-related mechanisms, bidirectional interactions, combined risk through metabolic syndrome, stroke outcomes, and clinical management considerations. Results: OSA is associated with increased cerebrovascular risk through intermittent hypoxemia-related oxidative stress and inflammation, sympathetic activation with blood pressure surges and sustained hypertension, endothelial dysfunction and atherosclerosis, impaired cerebral autoregulation, arrhythmogenesis, particularly atrial fibrillation and prothrombotic changes. DM increases stroke risk via accelerated atherosclerosis, cerebral small vessel disease, endothelial injury, hypercoagulability, glycemic variability, and cardioembolic mechanisms. Evidence indicates that coexisting OSA and DM are common and associated with greater vascular injury markers, higher rates of cerebrovascular events, and poorer post-stroke recovery. Conclusions: OSA and DM contribute to cerebrovascular complications through convergent mechanisms centered on metabolic syndrome, obesity, inflammation, vascular dysfunction, and thrombosis. These findings support proactive screening and coordinated management strategies to reduce cerebrovascular risk and improve outcomes. Full article

Behaviour management represents a complex dimension of the teaching profession, especially in contexts of high social vulnerability. This instrumental case study qualitatively analysed the experiences of four teachers from a technical–professional high school in Santiago, Chile, focusing on how they construct and sustain behaviour management in everyday classroom work. Data were generated through semi-structured interviews and analysed using qualitative content analysis. Findings foreground a central tension in which reactive management predominates over preventive strategies, shaping how teachers sustain pedagogical continuity under recurrent disruption. Teachers describe this work as a reflective construction negotiated between routines and adaptation to contingencies, supported by bonds of trust with students and informal peer collaboration within an institutional structure perceived as fragmented. These insights can inform teacher education by strengthening practice-oriented preparation for behaviour management and can support the refinement of educational coexistence policies in context-sensitive ways.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a type 2 inflammatory disease effectively treated with dupilumab, a monoclonal antibody that inhibits IL-4 and IL-13 signaling. Dupilumab is an effective treatment for type 2 inflammatory diseases such as CRSwNP. Although efficacy of dupilumab in controlling upper airway inflammation is well established, concerns have emerged regarding its potential cardiovascular effects. Emerging evidence suggests that IL-4/IL-13 signaling plays a protective role in post-myocardial infarction remodeling by promoting anti-inflammatory macrophage polarization, angiogenesis, and controlled fibrosis, especially during the early healing phase. Pharmacological blockade of the IL-4/IL-13 signaling pathway, such as that induced by dupilumab, may theoretically impair myocardial repair mechanisms, particularly in male patients who appear more responsive to these cytokines. Although rare, dupilumab-associated hypereosinophilia and myocarditis have been reported. In patients with pre-existing ischemic heart disease or heart failure, a multidisciplinary risk–benefit evaluation should be considered. Concomitant use of cardioprotective agents such as sacubitril/valsartan or SGLT2 inhibitors may help mitigate potential cardiac risks. Future studies are needed to clarify the safety and therapeutic implications of combining dupilumab with cardiovascular therapies in patients with coexisting CRSwNP and heart disease. This review critically evaluates emerging evidence of potential interference with post-infarction myocardial repair and highlights the importance of a multidisciplinary approach in managing patients with coexisting inflammatory and cardiovascular diseases. The aim of this review is to explore the available data on the cardiovascular impact of dupilumab and to provide possible future perspectives. Full article

Background/Objectives: The integration of molecular classification has significantly refined prognostic stratification in endometrial carcinoma (EC). However, a tumor subset harboring more than one molecular classifier challenges the current hierarchical classification systems, and their biological and clinical significance remains incompletely defined. Methods: We analyzed an expanded cohort of 150 EC patients using next-generation sequencing and immunohistochemistry, integrating molecular and clinicopathological data. Multiple-classifier ECs were identified and compared with those of single-classifier tumors sharing at least one molecular feature. A systematic review and meta-analysis including our cohort were also performed to estimate the incidence and distribution of multiple-classifier ECs. Results: In our cohort, 6% of ECs harbored molecular multiple-classifiers. POLEmut-MMRd/MSI tumors generally retained POLE-mutated features, including ultrahigh tumor mutational burden (TMB), early-stage disease, and favorable clinicopathological characteristics, consistent with a highly immunogenic phenotype. In contrast, MMRd/MSI-p53abn/TP53mut tumors were more frequently associated with adverse clinicopathological features and showed lower and heterogeneous TMB values, suggesting that the coexistence of TP53 alterations may modify the typical intermediate-risk of MMRd/MSI-only tumors. Triple-classifier tumors were exceedingly rare, precluding definitive conclusions regarding prognosis. The meta-analysis demonstrated an overall prevalence of multiple-classifier ECs of approximately 5.4%, with substantial inter-study heterogeneity largely attributable to differences in molecular testing strategies, analytical sensitivity, and variant interpretation criteria. Conclusions: Multiple-classifier ECs represent a small but clinically relevant subset encompassing biologically heterogeneous entities. Our findings highlight the limitations of current molecular classification hierarchies and underscore the need for harmonized molecular testing and standardized reporting to improve risk stratification and the management of multiple-classifier ECs.

Background: Chronic obstructive pulmonary disease (COPD) is increasingly recognized as a disorder linked to increased cardiovascular risk, often coexisting with coronary artery disease (CAD), yet angiographic data on coronary involvement in COPD remain limited. This study aimed to evaluate whether COPD is associated with a distinct angiographic pattern of CAD, focusing on vessel distribution. Methods: We retrospectively enrolled 94 patients who underwent coronary angiography between 2023 and 2024 for suspected or known CAD. Clinical data, comorbidities, laboratory testing, pulmonary function, electrocardiography, echocardiography, and angiography were collected. Participants were stratified into two groups: COPD (n = 47) and non-COPD (n = 47). Coronary vessels were classified by number, location, and diameter. The normality of continuous variables was assessed using the Shapiro–Wilk test. Non-normally distributed variables were compared using the Mann–Whitney U test, while Fisher’s exact test was used for categorical comparisons. A multivariable logistic regression model was performed to identify independent predictors of left main coronary artery (LMCA) disease at the patient level. The primary endpoint was the association between COPD and CAD severity. Results: Baseline characteristics, including age, sex, BMI, and smoking history, were comparable between groups. The overall extent of CAD, expressed as the number of diseased vessels, did not differ significantly (p = 0.1436). However, vessel-based analysis revealed a distinct pattern: COPD patients showed a significantly higher prevalence of left main coronary artery (LMCA) disease compared to non-COPD patients (14% vs. 4.7%, p < 0.001). At the patient level, LMCA disease was present in 15/47 (31.9%) COPD patients compared with 6/47 (12.8%) non-COPD patients (p = 0.046). Multivariable logistic regression confirmed that COPD was an independent predictor of LMCA disease (OR = 3.56, 95% CI: 1.12–11.29, p = 0.031) after adjustment for age, sex, smoking, diabetes, and chronic kidney disease. Intermediate-caliber vessels were most frequently affected in both groups, while small-caliber branches were less commonly involved in COPD patients. Conclusions: COPD is an independent predictor of LMCA disease despite a similar overall angiographic extent of CAD. These findings suggest a distinct, high-risk coronary phenotype in COPD and highlight the need for enhanced cardiovascular vigilance and integrated cardiopulmonary management in this population.

The digital transformation of the textile industry poses unique challenges due to its labor-intensive processes, complex global supply chains, and coexistence of traditional methods and emerging technologies. Despite the urgency of this transition, existing digital maturity models lack sector-specific frameworks and often fail to integrate multi-criteria decision-making (MCDM) methodologies for quantitative performance assessment. This study addresses these gaps by proposing a novel digital maturity model tailored specifically to the textile sector. The research employs an integrated decision-making framework using the Method Based on the Removal Effects of Criteria (MEREC) to determine objective criterion weights and the Operational Competitiveness Rating Analysis (OCRA) method to rank firm-level digital maturity performance. The findings indicate that Strategy is the most influential dimension, whereas Technology receives the lowest weight. At the sub-criterion level, Management Support, Market Analysis, and Vision and Strategic Awareness are the most critical factors, while Technology Usage Competency is less influential. The performance evaluation shows that Company A3 achieves the highest level of digital maturity, whereas Company A2 ranks lowest. The robustness of the proposed framework is comprehensively validated through a scenario-based sensitivity analysis and a comparative evaluation using the Additive Ratio Assessment System (ARAS) method. Overall, the results suggest that successful digital transformation in the textile sector depends primarily on strategic vision and managerial support rather than on technological infrastructure alone.

Multiple sclerosis (MS) is a chronic immune-mediated demyelinating disorder of the central nervous system, traditionally considered distinct from neuromuscular diseases, which primarily affect the peripheral nervous system, neuromuscular junction, or skeletal muscle. Growing clinical and experimental evidence, however, indicates that certain neuromuscular disorders may coexist with MS or shared overlapping pathophysiological, immunological, and metabolic mechanisms. This narrative review summarizes reported associations between MS and neuromuscular diseases, with particular focus on well-characterized overlaps such as Leber hereditary optic neuropathy (LHON)-associated MS (Harding’s disease), combined central and peripheral demyelination (CCPD), and myasthenia gravis (MG) co-occurring with MS. Additional associations with Charcot–Marie–Tooth disease, mitochondrial disorders with MS-like phenotypes, inherited and autoimmune myopathies, and rare syndromes such as Guillain–Barré syndrome are also discussed. This review highlights proposed mechanisms potentially linking these conditions, including immune dysregulation, T- and B-cell-mediated autoimmunity, antibody-driven demyelination, mitochondrial dysfunction, impaired neuromuscular transmission, and molecular mimicry. Limitations of the current literature are acknowledged, particularly the predominance of case reports for rare associations and the frequent lack of systematic screening for coexisting disorders. By integrating evidence from case series, cohort studies, and mechanistic research, this review provides a comprehensive overview of the biological and clinical intersections between MS and neuromuscular diseases. Enhanced understanding of these overlaps may improve diagnostic accuracy, guide individualized management strategies, and inform future research on shared neuroimmunological and neurodegenerative pathways.

Background/Objectives: The coexistence of chronic obstructive pulmonary disease (COPD) and type 2 diabetes mellitus (T2D) poses significant clinical challenges due to overlapping mechanisms of systemic inflammation, oxidative stress, hypoxia, and metabolic dysregulation. Patients with both conditions face higher risks of exacerbations, prolonged hospitalizations, cardiovascular events, and reduced quality of life. This review aims to summarize current evidence on the pathophysiological interplay between COPD and T2D and to evaluate the impact of lifestyle and pharmacologic interventions. Methods: A narrative review of the literature was conducted to evaluate the pathophysiological links between COPD and T2D, assess the effects of pharmacologic and lifestyle interventions, and highlight key gaps and priorities for future research, with an emphasis on integrated, evidence-based management for this high-risk population. Results: Lifestyle interventions, including smoking cessation and structured physical activity, remain foundational to management. Emerging evidence indicates that antidiabetic therapies, such as glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium–glucose cotransporter-2 inhibitors (SGLT-2is), may confer additional pulmonary, metabolic, and cardiovascular benefits. These agents modulate systemic inflammation, oxidative stress, endothelial function, and insulin sensitivity, potentially reducing COPD exacerbations, improving lung function, and enhancing survival. Safety concerns, including glucocorticoid-induced hyperglycaemia and hypoxia-related metabolic complications, underscore the need for careful monitoring and individualized therapy COPD patients. Conclusions: Optimal care requires a multidisciplinary, patient-centred approach integrating pulmonology, endocrinology, primary care, nutrition, and rehabilitation, alongside shared decision-making and patient education. Despite promising findings, critical knowledge gaps remain. Large, well-designed randomized controlled trials and standardized definitions are needed to guide personalized therapeutic strategies.

Introduction: Severe traumatic brain injury (sTBI) frequently coexists with polytrauma and often necessitates damage control neurosurgery (DCNS), where rapid decompression and temporary stabilization take precedence over definitive reconstruction. Within this context, anesthetic management must balance cerebral protection with ongoing resuscitation, yet high-quality DCNS-specific evidence remains limited. Materials and Methods: A comprehensive search of PubMed, Scopus, and Google Scholar (2015–2025) was conducted using MeSH terms and keywords related to neurotrauma, anesthesia, intracranial pressure, and perioperative management. Studies were included if they examined anesthetic or hemodynamic strategies in severe TBI or DCNS and reported relevant clinical or physiologic outcomes. Results: Nineteen articles addressing perioperative strategies for optimizing DCNS outcomes were analyzed. Discussion: Preoperative care emphasizes hemodynamic stabilization and permissive hypertension, damage control resuscitation including massive transfusion protocols, optimization of cerebral perfusion pressure (CPP) and neuromonitoring, and the use of hyperosmolar therapy. Transexamic acid can be used in sTBI safely but with unclear improvement in outcomes. Intraoperatively, propofol-based total intravenous anesthesia is generally preferred over volatile agents due to favorable effects on intracranial pressure (ICP), cerebral blood flow (CBF), autoregulation, and emergence. While historically contraindicated, ketamine and etomidate are now increasingly used as hemodynamically protective induction agents. Analgesic and sedative strategies prioritize dexmedetomidine and carefully titrated opioids to minimize respiratory depression and reduce postoperative complications. CPP and ICP-directed management relies on individualized blood pressure targets, vasopressor selection, lung-protective ventilation, and strict temperature control. Conclusions: Emerging evidence has suggested the benefit of DCNS for patient survival. Overall, perioperative care is guided largely by physiology and extrapolation, highlighting the need for standardized protocols. Full article

Inflammatory bowel diseases (IBDs) and metabolic disorders are increasingly recognized as interconnected conditions that frequently coexist and influence each other’s clinical course. Accumulating evidence indicates that patients with IBD face a substantial burden of obesity, metabolic syndrome, metabolic dysfunction-associated steatotic liver disease, osteoporosis, and type 2 diabetes. These associations appear to be driven by shared and interacting mechanisms, including intestinal barrier disruption, gut microbiota dysbiosis, chronic systemic inflammation, and adipose tissue-mediated immunometabolic pathways. Metabolic comorbidities may worsen IBD activity, reduce response to therapy, increase complications, and contribute to higher health care utilization. Conversely, intestinal inflammation and commonly used treatments, particularly corticosteroids, can adversely affect glucose metabolism, lipid metabolism, body composition and bone homeostasis. Advanced therapies have demonstrated variable metabolic effects, some of which may be beneficial through suppression of systemic inflammation. Recognition of these bidirectional interactions highlights the importance of routine metabolic screening and integrated, multidisciplinary management. Lifestyle interventions, nutritional optimization and individualized therapeutic strategies represent central parts of comprehensive management. Full article

Objective: To analyze multiple aspects of advanced bladder endometriosis surgery, based on the experience of an endometriosis reference center. Methods: This retrospective/prospective study included 80 consecutive patients with deep bladder endometriosis treated with laparoscopic surgery. Results: In 96.3% of cases, bladder endometriosis coexisted with other organ involvement: bowel (87.5%), uterus (61.3%), and ureters (37.5%); isolated bladder lesions occurred in 3.7%. Full-thickness bladder infiltration occurred in 36.4% of patients, and 71.8% had a history of surgery. The most frequent preoperative symptoms related to multiorgan involvement were dysmenorrhea (88.7%), dyschezia (75.0%), and dyspareunia (55.7%). Dysuria (55.7%), pollakiuria (17.9%), and urinary urgency (9.0%) were also reported. Shaving was performed in 45.0% of cases, resection in 40.0%, skinning in 15.0%, with two rare cases requiring bladder augmentation with bowel insert. Of all multiorgan surgeries (96.3% of cases), the most complex 30% were performed by a bi-disciplinary team of gynecologists and urologists. Postoperative complications occurred in 8 patients (10%) and were significantly associated with larger lesions, full-thickness infiltration, trigonum involvement, multiple organs opened, and prior surgery. Conclusions: Laparoscopic management of bladder endometriosis is feasible and effective, even in complex cases. Postoperative complications were linked to disease complexity but remained low, likely due to protective techniques used by the reference team. Optimal outcomes for the most difficult cases are more likely when procedures are performed by a bi-disciplinary team involving both oncological gynecologists specialized in deep endometriosis surgery and urologists. Given the heterogeneous clinical profiles of bladder endometriosis, treatment should be carried out in specialized centers where individualized surgical strategies can be implemented. Full article
