Portuguese Pancreatic Club Perspectives on Endoscopic Ultrasound-Guided and Surgical Treatment of Pancreatic Neuroendocrine Tumors.

Pancreatic neuroendocrine tumors (panNETs) are a group of neoplasms with heterogenous biological and clinical phenotypes. Although historically regarded as rare, the incidence of these tumors has been increasing, mostly owing to improvements in the detection of small, asymptomatic tumors with imaging. The heterogeneity of these lesions creates significant challenges regarding diagnosis, staging, and treatment. Endoscopic ultrasound (EUS) has improved the characterization of pancreatic lesions. Furthermore, EUS nowadays has evolved from a purely diagnostic modality to allow the performance of minimally invasive locoregional therapy for pancreatic focal lesions. The choice of treatment as well as the treatment goals depend on several factors, including tumor secretory status, grading, staging, and patient performance status. Surgery has been the mainstay for the management of these patients, particularly for localized, low-grade, large panNETs >2 cm. Over the last decade, a significant body of evidence has been accumulated evaluating the role of EUS for the ablative therapy of panNETs, namely by the use of chemoablative agents and radiofrequency. Although endoscopic techniques are not routinely recommended by international guidelines, they may be considered for the treatment of smaller lesions in patients who are unwilling or unfit for pancreatic surgery. In this review, we summarize the existing evidence on the interventional techniques for the treatment of patients with panNETs, focusing on the EUS-guided and surgical approaches.

Os tumores neuroendócrinos do pâncreas (panNETs) são um grupo de neoplasias com comportamento biológico e clínico heterogéneo. Embora historicamente considerados raros, a incidência desses tumores tem aumentado, algo que se atribui principalmente à melhoria na deteção de pequenos tumores assintomáticos em exames de imagem. A heterogeneidade destas lesões cria desafios significativos no que respeita ao seu diagnóstico, estadiamento e tratamento. A ultrassonografia endoscópica melhorou a caracterização das lesões pancreáticas. Concomitantemente, a ultrassonografia endoscópica, para além da vertente diagnóstica, evoluiu no sentido do desenvolvimento de capacidades terapêuticas, permitindo a realização de terapêutica locorregional de lesões pancreáticas focais de forma minimamente invasiva.A seleção do tratamento, bem como a definição dos seus objetivos, depende de diversos fatores, incluindo a atividade secretora da neoplasia, a sua atividade mitótica, o estadiamento e o status funcional do doente. A cirurgia é considerada a pedra basilar do tratamento destes doentes, particularmente para panNETs localizados, de baixo grau, com >2 cm. Ao longo da última década foi gerado um conjunto significativo de evidência relativamente ao papel da ultrassonografia endoscópica na terapêutica ablativa dos panNETs, nomeadamente através da utilização de agentes quimioablativos e de radiofrequência. Embora as recomendações internacionais não recomendem a utilização rotineira destas técnicas para o tratamento dos panNETs, as mesmas podem ser consideradas no tratamento de lesões de menores dimensões em doentes que não desejem ou que sejam considerados inaptos para cirurgia pancreática. Esta revisão visa resumir a evidência existente relativa às técnicas de intervenção para o tratamento de pacientes com panNETs, com foco nas abordagens cirúrgica e guiada por ultrassonografia endoscópica.

Portuguese Pancreatic Club Perspectives on Pancreatic Neuroendocrine Neoplasms: Diagnosis and Staging, Associated Genetic Syndromes and Particularities of Their Clinical Approach.

Pancreatic neuroendocrine neoplasms (panNENs) have been historically regarded as rare, but their incidence has raised more than 6-fold over the last 3 decades, mostly owing to improvement in the detection of small asymptomatic tumours with imaging. Early detection and proper classification and staging are essential for the prognosis and management of panNENs. Histological evaluation is mandatory in all patients for the diagnosis of panNEN. Regarding localization and staging, multiphasic contrast-enhanced computer tomography is considered the imaging study of choice. Nevertheless, several other diagnostic modalities might present complementary information that can help in diagnosis and staging optimization: magnetic resonance imaging, somatostatin receptor imaging using positron emission tomography in combination with computed tomography (PET/CT), PET/CT with fluorodeoxyglucose (18F-FDG), and endoscopic ultrasound. Approximately 10% of panNENs are due to an inherited syndrome, which includes multiple endocrine neoplasia type 1, von Hippel-Lindau disease, neurofibromatosis type 1 (NF-1), tuberous sclerosis complex, and Mahvash disease. In this review, the Portuguese Pancreatic Club summarizes the classification, diagnosis, and staging of panNENs, with a focus on imaging studies. It also summarizes the characteristics and particularities of panNENs associated with inherited syndromes.

As neoplasias neuroendócrinas pancreáticas (panNENs) são historicamente consideradas raras, embora a sua incidência tenha aumentado mais de 6 vezes nas últimas três décadas, principalmente devido à otimização do diagnóstico de tumores pequenos e assintomáticos em exames de imagem. A deteção precoce, a classificação e o estadiamento adequados são essenciais para o prognóstico e abordagem dos panNENs. A avaliação histológica é obrigatória em todos os doentes para o diagnóstico de panNENs. Para a localização e estadiamento, ​​a TC multifásica com contraste é considerada o estudo de imagem de eleição. Contudo, várias outras modalidades diagnósticas podem apresentar informações complementares que podem auxiliar no diagnóstico e na otimização do estadiamento: ressonância magnética, PET/CT dos receptores da somatostatina, PET/CT [18F]FDG e ecoendoscopia. Aproximadamente 10% dos panNENs estão relacionados com síndromes hereditários, que incluem neoplasia endócrina múltipla tipo 1 (MEN1), doença de von Hippel-Lindau (VHL), neurofibromatose tipo 1 (NF1), complexo de esclerose tuberosa (TSC) e doença de Mahvash. Neste artigo, o Clube Português de Pâncreas aborda a classificação, diagnóstico e estadiamento de panNENs, ​​com foco nos estudos de imagem, bem como resume as características e particularidades dos panNENs associados aos síndromes hereditários.

Randomized Controlled Trial Comparing Open Simple Prostatectomy or Prostate Artery Embolization in Large Prostates: Clinical and Urodynamic Assessment - PoPAE Study.

OBJECTIVE: To evaluate the effects of Prostate artery embolization (PAE) and open simple prostatectomy (OP) on lower urinary tract symptoms and urodynamic parameters in subjects with prostate size >80cc³. METHODS: PoPAE study (OP or PAE) was a randomized, open-label controlled trial performed between January 2020 and May 2022. Subjects with large prostates (>80cc³), urodynamic parameters meeting obstruction criteria (Bladder Outlet Obstruction Index-BOOI>40), and good detrusor function (Bladder contractility index>100) were included. The primary and co-primary endpoints were the variation in peak flow rate on uroflowmetry (Qmax) and BOOI. The secondary endpoints were the IPSS and ultrasonographic changes. RESULTS: Twenty three and 25 subjects underwent PAE and OP were evaluated, respectively. At baseline, the 2 groups have shown similar clinical, radiological, laboratory, and urodynamic parameters. After 6 months, Qmax improved 8,3 ± 4.17 mL/sec in PAE and 15.1 ± 8.04 mL/sec in OP (mean difference 6.78 in favor of PE; P = .012 [CI -9.00 to -3.00]). After treatment, 88% of those men underwent OP were classified as unobstructed or equivocal (BOOi<40). On the other hand, 70% of subjects underwent PAE remained obstructed (BOOI>40) and none of them shifted to unobstructed status (BOOI<20). It was observed a similar reduction in IPSS and PVR in both groups. CONCLUSION: PAE was inferior to conventional surgery for releasing BOO and improving peak urinary flow in large prostates. Nevertheless, PAE was able to improve symptoms and PVR, and might be an alternative method in selected patients.

Underwater Endoscopic Mucosal Resection Vs Conventional Endoscopic Mucosal Resection for Superficial Nonampullary Duodenal Epithelial Tumors in the Western Setting.

BACKGROUND & AIMS: Conventional endoscopic mucosal resection (C-EMR) is established as the primary treatment modality for superficial nonampullary duodenal epithelial tumors (SNADETs), but recently underwater endoscopic mucosal resection (U-EMR) has emerged as a potential alternative. The majority of previous studies focused on Asian populations and small lesions (≤20 mm). We aimed to compare the efficacy and outcomes of U-EMR vs C-EMR for SNADETs in a Western setting. METHODS: This was a retrospective multinational study from 10 European centers that performed both C-EMR and U-EMR between January 2013 and July 2023. The main outcomes were the technical success, procedure-related adverse events (AEs), and the residual/recurrent adenoma (RRA) rate, evaluated on a per-lesion basis. We assessed the association between the type of endoscopic mucosal resection and the occurrence of AEs or RRAs using mixed-effects logistic regression models (propensity scores). Sensitivity analyses were performed for lesions ≤20 mm or >20 mm. RESULTS: A total of 290 SNADETs submitted to endoscopic resection during the study period met the inclusion criteria and were analyzed (C-EMR: n = 201, 69.3%; U-EMR: n = 89, 30.7%). The overall technical success rate was 95.5% and comparable between groups. In logistic regression models, compared with U-EMR, C-EMR was associated with a significantly higher frequency of overall delayed AEs (odds ratio [OR], 4.95; 95% CI, 2.87-8.53), postprocedural bleeding (OR, 7.92; 95% CI, 3.95-15.89), and RRAs (OR, 3.66; 95% CI, 2.49-5.37). Sensitivity analyses confirmed these results when solely considering either small (≤20 mm) or large (>20 mm) lesions. CONCLUSIONS: Compared with C-EMR, U-EMR was associated with a lower rate of overall AEs and RRAs, regardless of lesion size. Our results confirm the possible role of U-EMR as an effective and safe technique in the management of SNADETs.

Multisegmented esophageal fully covered self-expandable metal stent for palliation of malignant dysphagia: a prospective, multicenter feasibility and safety study.

BACKGROUND AND AIMS: A novel multisegmented esophageal fully covered self-expandable metal stent (FCSEMS) was designed to reduce stent migration, which is seen in up to 30% of patients. The goal of this study was to evaluate the safety and efficacy of the multisegmented FCSEMS. METHODS: This multicenter prospective study aimed to include 30 patients undergoing palliative stent placement. Efficacy, defined as technically successful stent placement and dysphagia scores, and safety, defined as the number of adverse events (AEs) and serious AEs (SAEs), were measured. RESULTS: The study was prematurely terminated due to safety concerns after including 23 patients (mean ± standard deviation age, 72 ± 10 years; 78% male). Stent placement was technically successful in 21 patients (91%), and dysphagia scores had improved in all patients with successful stent placement. SAEs were reported in 16 (70%) patients. Stent-related mortality occurred in 3 patients (13%). CONCLUSIONS: The multisegmented FCSEMS successfully treated malignant dysphagia. The study was prematurely terminated, however, because stent placement was associated with a relatively high SAE rate. (Clinical trial registration number: NCT04415463.).

Severe Soft Tissue Loss on Dorsum of the Foot with Irreparable Hallucis Extensors: An Orthoplastic Reconstruction Case Report.

CASE: A motorcycle accident resulted in severe soft tissue loss on the foot's dorsum with irreparable hallucis extensors, with exposure of the first metatarsal and hallux. An arthrodesis of the hallux interphalangeal joint, a transfer of the second toe's extensor digitorum longus, and an anterolateral thigh free flap were performed simultaneously. The patient obtained a fair result and could wear regular shoes. DISCUSSION: This is the first report describing this orthoplastic reconstructive option in these complex injuries. It replenished both hallux extensor tendons and soft tissue coverage losses without severely compromising the foot's contour, recreating anatomy and function.

Crosslinked chitosan microparticles as a safe and efficient DNA carrier for intranasal vaccination against cutaneous leishmaniasis.

Intranasal (i.n.) vaccination with adjuvant-free plasmid DNA encoding the leishmanial antigen LACK (LACK DNA) has shown to induce protective immunity against both cutaneous and visceral leishmaniasis in rodents. In the present work, we sought to evaluate the safety and effectiveness of d,l-glyceraldehyde cross-linked chitosan microparticles (CCM) as a LACK DNA non-intumescent mucoadhesive delivery system. CCM with 5 µm of diameter was prepared and adsorbed with a maximum of 2.4 % (w/w) of DNA with no volume alteration. Histological analysis of mouse nostrils instilled with LACK DNA / CCM showed microparticles to be not only mucoadherent but also mucopenetrant, inducing no local inflammation. Systemic safeness was confirmed by the observation that two nasal instillations one week apart did not alter the numbers of bronchoalveolar cells or blood eosinophils; did not alter ALT, AST and creatinine serum levels; and did not induce cutaneous hypersensitivity. When challenged in the footpad with Leishmania amazonensis, mice developed significantly lower parasite loads as compared with animals given naked LACK DNA or CCM alone. That was accompanied by increased stimulation of Th1-biased responses, as seen by the higher T-bet / GATA-3 ratio and IFN-γ levels. Together, these results demonstrate that CCM is a safe and effective mucopenetrating carrier that can increase the efficacy of i.n. LACK DNA vaccination against cutaneous leishmaniasis.

Best Practices in Esophageal, Gastroduodenal, and Colonic Stenting.

Endoscopic stenting is an area of endoscopy that has witnessed noteworthy advancements over the last decade, resulting in evolving clinical practices among gastroenterologists around the world. Indications for endoscopic stenting have progressively expanded, becoming a frequent part of the management algorithm for various benign and malignant conditions of the gastrointestinal tract, from esophagus to rectum. In addition to expanded indications, continuous technological enhancements and development of novel endoscopic stents have resulted in an increased success of these approaches and, in some cases, allowed new applications. This review aimed to summarize best practices in esophageal, gastroduodenal, and colonic stenting.

Clinical and Urodynamic results of the Argus T® sling in moderate and severe male stress urinary incontinence after radical prostatectomy - a 5 year prospective study

ABSTRACT Purpose: Sling as a therapeutic option for male stress urinary incontinence (SUI) has been reviewed in the last two decades, as it is a relatively simpliest surgery compared to artificial urinary sphincter and has the ability to modulate urethral compression. This study aims to evaluate the efficacy, rate of complications, quality of life and the effects on bladder emptying of the Argus T® compressive and ajustable sling in moderate and severe male SUI treatment. Materials and Methods: Men eligible for stress urinary incontinence treatment after radical prostatectomy were recruited and prospectively evaluated, from March 2010 to November 2016. It was selected outpatient men with moderate and severe SUI, after 12 months of radical prostatectomy, who have failed conservative treatment. All patients had a complete clinical and urodynamic pre and post treatment evaluation, by means of clinical history, physical examination, urine culture, 1-hour pad test and ICIq-SF questionnaire. The UDS was performed after 12, 18 and 24 months postoperatively. Results: Thirty-seven men underwent sling surgery, 19 patients (51.4%) with moderate and 18 (48.6%) with severe SUI. The minimum follow-up time was 5 years. Overall, we had a success rate of 56.7% at 60 months follow-up. After surgery, we did not observe significant changes in the urodynamic parameters evaluated during the follow-up. No patient had urodynamic bladder outlet obstruction (BOO) after sling implantation. Readjustment of the Argus T® sling was performed in 16 (41%) of the patients and 51% of the patients reported some adverse event. Conclusion: We demonstrate a long-term efficacy and safety of Sling Argus T® as an alternative to moderate and severe male SUI treatment. Furthermore, in our study bulbar urethra compression does not lead to bladder outlet obstruction.

Identification of Immunodominant Proteins of the Leishmania (Viannia) naiffi SubProteome as Pan-Specific Vaccine Targets against Leishmaniasis.

Leishmaniasis is a wide-spectrum disease caused by parasites from Leishmania genus. A well-modulated immune response that is established after the long-lasting clinical cure of leishmaniasis can represent a standard requirement for a vaccine. Previous studies demonstrated that Leishmania (Viannia) naiffi causes benign disease and its antigens induce well-modulated immune responses in vitro. In this work we aimed to identify the immunodominant proteins present in the soluble extract of L. naiffi (sLnAg) as candidates for composing a pan-specific anti-leishmaniasis vaccine. After immunoblotting using cured patients of cutaneous leishmaniasis sera and proteomics approaches, we identified a group of antigenic proteins from the sLnAg. In silico analyses allowed us to select mildly similar proteins to the host; in addition, we evaluated the binding potential and degree of promiscuity of the protein epitopes to HLA molecules and to B-cell receptors. We selected 24 immunodominant proteins from a sub-proteome with 328 proteins. Homology analysis allowed the identification of 13 proteins with the most orthologues among seven Leishmania species. This work demonstrated the potential of these proteins as promising vaccine targets capable of inducing humoral and cellular pan-specific immune responses in humans, which may in the future contribute to the control of leishmaniasis.

Endoscopic treatment of upper gastrointestinal postsurgical leaks: a narrative review.

Upper gastrointestinal postsurgical leaks are life-threatening conditions with high mortality rates and are one of the most feared complications of surgery. Leaks are challenging to manage and often require radiological, endoscopic, or surgical intervention. Steady advancements in interventional endoscopy in recent decades have allowed the development of new endoscopic devices and techniques that provide a more effective and minimally invasive therapeutic option compared to surgery. Since there is no consensus regarding the most appropriate therapeutic approach for managing postsurgical leaks, this review aimed to summarize the best available current data. Our discussion specifically focuses on leak diagnosis, treatment aims, comparative endoscopic technique outcomes, and combined multimodality approach efficacy.

Technical Review on Endoscopic Treatment Devices for Management of Upper Gastrointestinal Postsurgical Leaks.

Upper gastrointestinal postsurgical leaks are challenging to manage and often require radiological, endoscopic, or surgical intervention. Nowadays, endoscopy is considered the first-line approach for their management, however, there is no definite consensus on the most appropriate therapeutic approach. There is a wide diversity of endoscopic options, from close-cover-divert approaches to active or passive internal drainage approaches. Theoretically, all these options can be used alone or with a multimodality approach, as each of them has different mechanisms of action. The approach to postsurgical leaks should always be tailored to each patient, taking into account the several variables that may influence the final outcome. In this review, we discuss the important developments in endoscopic devices for the treatment of postsurgical leaks. Our discussion specifically focuses on principles and mechanism of action, advantages and disadvantages of each technique, indications, clinical success, and adverse events. An algorithm for endoscopic approach is proposed.

The importance of inflammatory biomarkers in non-specific acute and chronic low back pain: a systematic review.

OBJECTIVE: The purpose of this study was to systematically review the evidence on inflammatory biomarkers as analytic predictors of non-specific low back pain (NsLBP). Low back pain (LBP) is the number one cause of disability globally, posing a major health problem that causes an enormous social and economic burden, and there is an increasing interest on the importance of biomarkers in quantifying and even emerge as potential therapeutic tools to LBP. METHODS: A systematic search was conducted on July 2022 in Cochrane Library, MEDLINE and Web of Science for all the available literature. Cross-sectional, longitudinal cohort or case-control studies that evaluated the relationship between inflammatory biomarkers collected from blood samples and low back pain in humans were considered eligible for inclusion, as well as prospective and retrospective studies. RESULTS: The systematic database search resulted in a total of 4016 records, of which 15 articles were included for synthesis. Sample size comprised a total of 14,555 patients with LBP (acute LBP (n = 2073); chronic LBP (n = 12482)) and 494 controls. Most studies found a positive correlation between classic pro-inflammatory biomarkers and NsLBP, namely C-reactive protein (CRP), interleukin 1 (IL-1) and IL-1ß, interleukin 6 (IL-6) and tumour necrosis factor α (TNF-α). On the other hand, anti-inflammatory biomarker interleukin 10 (IL-10) demonstrated a negative association with NsLBP. Four studies have made direct comparisons between ALBP and CLBP groups regarding their inflammatory biomarkers profile. CONCLUSIONS: This systematic review found evidence of increased levels of pro-inflammatory biomarkers CRP, IL-6 and TNF-α and decreased levels of anti-inflammatory biomarker IL-10 in patients with LBP. Hs-CRP was not correlated with LBP. There is insufficient evidence to associate these findings with the degree of pain severity or the activity status of the lumbar pain over time.

Barriers and facilitators for safe sex behaviors in students from universidad de Santiago de Chile (USACH) through the COM-B model.

BACKGROUND: Unsafe sex is one of the main morbidity and mortality risk factors associated with sexually transmitted infections (STIs) in young people. Behavioral change interventions for promoting safe sex have lacked specificity and theoretical elements about behavior in their designs, which may have affected the outcomes for HIV/AIDS and STI prevention, as well as for safe sex promotion. This study offers an analysis of the barriers and facilitators that, according to the university students who participated in the focus groups, impede or promote the success of interventions promoting healthy sexuality from the perspective of the actions stakeholders should undertake. In turn, this study proposes intervention hypotheses based on the Behavior Change Wheel which appears as a useful strategy for the design of intervention campaigns. METHODS: Two focus groups were organized with students from Universidad de Santiago de Chile (USACH). The focus groups gathered information about the perceptions of students about sex education and health, risk behaviors in youth sexuality, and rating of HIV/AIDS and STI prevention campaigns. In the focus groups, participants were offered the possibility of presenting solutions for the main problems and limitations detected. After identifying the emerging categories related to each dimension, a COM-B analysis was performed, identifying both the barriers and facilitators of safe sex behaviors that may help orient future interventions. RESULTS: Two focus groups were organized, which comprised 20 participants with different sexual orientations. After transcription of the dialogues, a qualitative analysis was performed based on three axes: perception about sex education, risk behaviors, and evaluation of HIV/AIDS and STI prevention campaigns. These axes were classified into two groups: barriers or facilitators for safe and healthy sexuality. Finally, based on the Behavior Change Wheel and specifically on its 'intervention functions', the barriers and facilitators were integrated into a series of actions to be taken by those responsible for promotion campaigns at Universidad de Santiago. The most prevalent intervention functions are: education (to increase the understanding and self-regulation of the behavior); persuasion (to influence emotional aspects to promote changes) and training (to facilitate the acquisition of skills). These functions indicate that specific actions are necessary for these dimensions to increase the success of promotional campaigns for healthy and safe sexuality. CONCLUSIONS: The content analysis of the focus groups was based on the intervention functions of the Behavior Change Wheel. Specifically, the identification by students of barriers and facilitators for the design of strategies for promoting healthy sexuality is a useful tool, which when complemented with other analyses, may contribute improving the design and implementation of healthy sexuality campaigns among university students.
