Eighteen years of experience in laparoscopic implantation of artificial urinary sphincter in women with intrinsic sphincter deficiency.

INTRODUCTION AND OBJECTIVES: Artificial urinary sphincter (AUS) is a treatment option for women with stress urinary incontinence (SUI) after failure of previous surgery or as a primary procedure in severe intrinsic sphincter deficiency (ISD). The aim of the study was to assess the long-term efficacy and risk factors for surgical revision and definitive explantation of AUS laparoscopic implantation in female patients. METHODS: A retrospective review of all women submitted to AUS implantation between April 2005 and March 2023 was conducted. The AUS was implanted via transperitoneal laparoscopic approach, by two experienced surgeons. The primary endpoint was postoperative continence. Continence was defined as no leakage and no pad usage or leakage and/or pad usage with no impact on social life and failure as leakage and/or pad usage impacting social life. As secondary outcomes, clinical predictive factors for AUS revision and definitive explantation were evaluated. RESULTS: In the last 18 years, females with a mean age of 68±12 years-old were submitted to laparoscopic implantation of AUS. Early overall complication rate was 16%, but only one case was Clavien-Dindo ≥3. After a median follow-up of 67 months, 22.2% of the patients needed a device revision, the majority due to mechanical device dysfunction. AUS definitive explantation was performed in 16%, mainly due to urethral/vaginal erosion (9.9%) and infection (6.2%). Patients with age ≥70 years and follow-up ≥10 years significantly predisposed for device revision. At the time of the last follow-up, 72% of the patients were keeping the urinary continency. CONCLUSIONS: Laparoscopic AUS implantation in females is an effective treatment for SUI due to ISD. Meanwhile, adequate patient selection, multidisciplinary evaluation and careful expectation management are essential to achieving good results, concerning their significant complication rate.

Predictors of prostate cancer detection in MRI PI-RADS 3 lesions - Reality of a tertiary center.

INTRODUCTION AND OBJECTIVES: The Prostate Imaging Reporting and Data System (PI-RADS) score reports the likelihood of a clinically significant prostate cancer (CsPCa) based on various multiparametric prostate magnetic resonance imaging (mpMRI) characteristics. The PI-RADS category 3 is an intermediate status, with an equivocal risk of malignancy. The PSA density (PSAD) has been proposed as a tool to facilitate biopsy decisions on PI-RADS category 3 lesions. The objective of this study is to determine the frequency of CsPCa, assess the diagnostic value of targeted biopsy and identify clinical predictors to improve the CsPCa detection rate in PI-RADS category 3 lesions. METHODS: Between 1st January 2017 and 31st December 2022, a total of 1661 men underwent a prostate biopsy at our institution. Clinical and mpMRI data of men with PI-RADS 3 lesions was reviewed. The study population was divided into two groups: target group, including those submitted to systematic plus targeted biopsy versus non-target group when only systematic or saturation biopsy were performed. Patients with PI-RADS 3 lesions were divided into three categories based on pathological biopsy results: benign, clinically insignificant disease (score Gleason = 6 or International Society of Urologic Pathologic (ISUP) 1) and clinically significant cancer (score Gleason ≥ 7 (3+4) or ISUP ≥ 2) according to target and non-target group. Univariate and multivariate analyses were performed to identify clinical predictors to improve the CsPCa detection rate in PI-RADS category 3 lesions. RESULTS: A total of 130 men with PIRADS 3 index lesions were identified. Pathologic results were benign in 77 lesions (59.2%), 19 (14.6%) were clinically insignificant (Gleason score 6) and 34 (26.2%) were clinically significant (Gleason score 7 or higher). Eighty-seven of the patients were included in the target group (66.9%) and 43 in the non-target group (33.1%). The CsPCa detection was higher in the non-target group (32.6%, n = 14 vs 23.0%, n = 20 respectively). When systematic and target biopsies were jointly performed, if the results of systematic biopsies are not considered and only the results of target biopsies are taken into account, a CsPCa diagnosis would be missed on 9 patients. The differences of insignificant cancer and CsPCa rates among the target or non-target group were not statistically significant (p = 0.50 and p = 0.24, respectively). on multivariate analysis, the abnormal DRE and lesions localized in Peripheral zone (PZ) were significantly associated with a presence of CsPCa in PI-RADS 3 lesions (oR = 3.61, 95% CI [1.22,10.72], p = 0.02 and oR = 3.31, 95% CI [1.35, 8.11], p = 0.01, respectively). A higher median PSAD significantly predisposed for CsPCa on univariate analyses (p = 0.05), however, was not significant in the multivariate analysis (p = 0.76). In our population, using 0.10 ng/ml/ml as a cut-off to perform biopsy, 41 patients would have avoided biopsy (31.5%), but 5 cases of CsPCa would not have been detected (3.4%). We could not identify any statistical significance between other clinical and imagiological variables and CsPCa detection. CONCLUSIONS: PI-RADS 3 lesions were associated with a low likelihood of CsPCa detection. A systematic biopsy associated or not with target biopsy is essential in PI-RADS 3 lesions, and targeted biopsy did not demonstrate to be superior in the detection of CsPCa. The presence of abnormal DRE and lesions localized in PZ potentially predict the presence of CsPCa in biopsied PI-RADS 3 lesions.

Comparison of Incidence and Prognosis of Myocardial Injury in Patients with COVID-19-Related Respiratory Failure and Other Pulmonary Infections: A Contemporary Cohort Study.

Myocardial injury (MI) is frequent in critically ill patients with COVID-19, but its pathogenesis remains unclear. We hypothesized that MI is not solely due to viral infection by SARS-CoV-2 but rather due to the common pathophysiological mechanisms associated with severe pulmonary infections and respiratory failure. This contemporary cohort study was designed to compare the incidence of MI in patients with acute respiratory failure caused by COVID-19 to patients with other pulmonary infections. In addition, we aimed to investigate whether MI was a distinct risk factor for in-hospital mortality in patients with COVID-19 compared to those with non-COVID-19 infections. This study included 1444 patients with COVID-19 (55.5% men; age 58 (46;68) years) and 182 patients with other pulmonary infections (46.9% men; age 62 (44;73) years). The incidence of MI at ICU admission was lower in COVID-19 patients (36.4%) compared to non-COVID-19 patients (56%), and this difference persisted after adjusting for age, sex, coronary artery disease, heart failure, SOFA score, lactate, and C-reactive protein (RR 0.84 (95% CI, 0.71-0.99)). MI at ICU admission was associated with a 59% increase in mortality (RR 1.59 (1.36-1.86); p < 0.001), and there was no significant difference in the mortality between patients with COVID-19 and those with other pulmonary infections (p = 0.271). We concluded that MI is less frequent in patients with critical COVID-19 pneumonia and respiratory failure compared to those with other types of pneumonia. The occurrence of MI is a significant risk factor for in-hospital mortality, regardless of the etiology of the pulmonary infection.

Classifying micropollutants by environmental risk in groundwater using screening analysis associated to a hybrid multicriteria method combining (Q)SAR tools, fuzzy AHP and ELECTRE.

This study aimed to evaluate and monitor pesticides in groundwater of the Serra Geral aquifer, located in the Paraná Basin 3 (southern Brazil), using Liquid Chromatography coupled with a Quadrupole-Time-of-Flight Mass Spectrometer (LC-QTOF MS). A total of 117 samples, collected in three different moments, were analyzed over 36 months. Groundwater samples from 35 wells and four surface water points were monitored in each sampling campaign. A pesticide screening methodology was proposed with the tentative identification of 1607 pesticides and pesticide metabolites. The application of the proposed methodology resulted in the verification of 29 pesticides and pesticide metabolites, 7 as confirmed analytes and 22 as suspect compounds. (Q)SAR in silico predictions and GUS index calculation provided data on the potential environmental risk of the identified compounds, with eight endpoints considered. After in silico predictions, an alternative hybrid multicriteria method was applied, combining the weighting of endpoints of fuzzy AHP and micropollutants classification by environmental risk using ELECTRE. The fuzzy AHP results indicated the greatest importance of mutagenicity among the eight evaluated indicators, while the scarce influence of the physicochemical properties on the environmental risk suggested their exclusion from the model. Accordingly, the ELECTRE results highlighted the prevalence of thiamethoxam and carbendazim as the most dangerous for the environment. The application of the proposed method enabled the selection of the compounds that must be monitored, considering mutagenicity and toxicity predictions for environmental risk analysis.

Adipose Tissue-Derived Stromal/Stem Cells Transplantation with Cholecalciferol Supplementation in Recent-Onset Type 1 Diabetes Patients: Twelve Months Follow-Up.

To evaluate safety and therapeutic effect along 12 months of allogenic adipose tissue-derived stromal/stem cells (ASCs) transplantation with cholecalciferol (VITD) in patients with recent-onset type 1 diabetes (T1D). Prospective, phase II, open trial, pilot study in which patients with recent onset T1D received ASCs (1xKgx106 cells) and VITD 2000UI/day for 12 months (group 1) and were compared to controls with standard insulin therapy (group 2). Adverse events, C-peptide area under the curve (CPAUC), insulin dose, HbA1c and frequency of FoxP3+ in CD4+ or CD8+ T-cells(flow cytometry) were evaluated at baseline(T0), after 3(T3), 6(T6) and 12 months(T12). Eleven patients completed follow up (7:group 1;4:group 2). Group 1 had lower insulin requirement at T3(0.24±0.18vs0.53±0.23UI/kg,p=0.04), T6(0.24±0.15vs0.66±0.33 UI/kg,p=0.04) and T12(0.39±0.15vs0.74±0.29 UI/Kg,p=0.04).HbA1c was lower at T6 (50.57±8.56vs72.25±10.34 mmol/mol,p=0.01), without differences at T12 (57.14±11.98 in group 1 vs. 73.5±14.57 mmol/min in group 2, p=0.16). CPAUC was not significantly different between groups at T0(p=0.07), higher in group 1 at T3(p=0.04) and T6(p=0.006), but similar at T12(p=0.23). IDAA1c was significantly lower in group 1 than group 2 at T3,T6 and T12 (p=0.006, 0.006 and 0.042, respectively). IDDA1c was inversely correlated to FoxP3 expression in CD4 and CD8+ T cells at T6 (p<0.001 and p=0.01, respectively). In group 1, one patient had recurrence of a benign teratoma that was surgically removed, not associated to the intervention. ASCs with VITD without immunosuppression were safe and associated lower insulin requirements, better glycemic control, and transient better pancreatic function in recent onset T1D, but the potential benefits were not sustained.

Thermal and volumetric assessment of endodontic filling techniques using infrared thermography and micro-CT.

PURPOSE: To assess root temperature during filling techniques and quantify the volume of endodontic filling materials using infrared thermography (IT) and micro-computed tomography (micro-CT). METHODS: Ninety premolars were divided into three groups: lateral condensation (LC), single cone (SC) and thermomechanical compaction (TMC). For thermal analysis, 45 teeth were assessed using a FLIR T650sc IT camera during filling techniques and 45 teeth were scanned using a Nikon micro-CT to assess gutta-percha, cement, and void volumes. Descriptive and inferential statistical analyses were performed (non-parametric Mann-Whitney test, Kruskal-Wallis test, and Friedman test with Tukey's bidirectional analysis of variance). RESULTS: TMC showed the highest temperature increase at 15 s after the procedure and a significant temperature decrease at 45 s after its completion. TMC showed the largest volume of gutta-percha and LC the highest void volume. CONCLUSION: The temperature increase generated by gutta-percha endodontic filling techniques is within acceptable limits. A greater volume of endodontic cement was observed for the SL and LC filling techniques.

The chemistry of Vernonanthura nudiflora (Less.) H. Rob. flowers and its antimicrobial activities.

Twenty-one known specialised metabolites were isolated from the flowers of Vernonanthura nudiflora (Less.) H. Rob., the structures of the compounds were established based on 1 D and 2 D NMR spectroscopic experiments. Others 28 compounds were putatively identified using the dereplication technique by UHPLC-HRMS/MS. Twenty-three of the compounds are being reported for the first time in this species. The mixture of sesquiterpene lactones piptocarphins A and B (17 + 18), and the flavone velutin (14) were tested against several microorganisms and showed promising activity against Mycobacterium tuberculosis with MIC of 15.6 µg/mL and 31.2 µg/mL, respectively. Furthermore, 17 + 18 showed greater cytotoxicity against VERO cells (IC50 = 7.0 ± 1.73) compared to compound 14 (IC50 85.0 ± 10.6 µg/mL). These findings reveal the feasibility of using the UHPLC-ESI-HRMS/MS-based dereplication strategy in complex fractions to identify specialised metabolites, moreover to V. nudiflora flowers being a source of compounds with antimycobacterial potential.

Perception of health, quality of life and functional capacity in adults and elderly after hospitalization due to complications of COVID-19 - a longitudinal study with 6-month follow-up / Percepción de salud, calidad de vida y capacidad funcional en adultos y ancianos poshospitalización por complicaciones del COVID-19 - estudio longitudinal con seguimiento de seis meses / Percepção de saúde, qualidade de vida e capacidade funcional em adultos e idosos pós-internação hospitalar em função de complicações da COVID-19 - estudo longitudinal com follow-up de seis meses

ABSTRACT The study aims to evaluate the perception of health, quality of life and functional capacity during six months after COVID-19-related hospitalization. This is a prospective longitudinal study carried out at Universidade São Judas Tadeu (USJT) in partnership with the Instituto Ânima Brasil. Thirteen adult participants, including young and older adults, were evaluated, had a confirmed diagnosis of COVID-19 and were hospitalized. A characterization and interdisciplinary questionnaire built by the researchers was used to assess health perception, quality of life, and functional capacity of participants. In this study, participants were followed for a 6-month period and the main results obtained were: the identification of a significant increase in walking time after three months (p=0.002) as well as an improvement in the perception of quality of life (p=0.002). In addition, the levels of tiredness and physical activity were evaluated; the mean responses were "little tired" and "irregularly active," respectively, and remained unchanged over six months. Considering that patients who were hospitalized due to COVID-19 showed a reduction in the perception of quality of life and walking time soon after the hospital period, it was identified that over time they tend to improve these perceptions.

A walk on the wild side: Wild ungulates as potential reservoirs of multi-drug resistant bacteria and genes, including Escherichia coli harbouring CTX-M beta-lactamases.

Extended-spectrum ß-lactamases (ESBL)-producing Enterobacterales have been classified as critical priority pathogens by the World Health Organization (WHO). ESBL are universally distributed and, in 2006, were firstly reported on a wild animal. Understanding the relative contributions of wild animals to ESBL circulation in the environment is urgently needed. In this work, we have conducted a nationwide study in Portugal to investigate the occurrence of bacteria carrying clinically significant antimicrobial resistance genes (ARG), using widely distributed wild ungulates as model species. A total of 151 antimicrobial resistant-Enterobacterales isolates were detected from 181 wild ungulates: 50% (44/88) of isolates from wild boar (Sus scrofa), 40.3% (25/62) from red deer (Cervus elaphus), 41.4% (12/29) from fallow deer (Dama dama) and 100% (2/2) from mouflon (Ovis aries subsp. musimon). Selected isolates showed a diversified resistance profile, with particularly high values corresponding to ampicillin (71.5%) and tetracycline (63.6%). Enterobacterales strains carried blaTEM, tetA, tetB, sul2, sul1 or dfrA1 ARG genes. They also carried blaCTX-M-type genes, which are prevalent in human infections, namely CTX-M-14, CTX-M-15 and CTX-M-98. Strikingly, this is the first report of CTX-M-98 in wildlife. Almost 40% (n = 59) of Enterobacterales were multi-drug resistant. The diversity of plasmids carried by ESBL isolates was remarkable, including IncF, K and P. This study highlights the potential role of wild ungulates as environmental reservoirs of CTX-M ESBL-producing E. coli and in the spill-over of AMR bacteria and their determinants. Our findings suggest that wild ungulates are useful as strategic sentinel species of AMR in terrestrial environments, especially in response to potential sources of anthropogenic pollution, providing early warning of potential risks to human, animal and environmental health.

Long-term outcomes of Altis® single-incision sling procedure for stress urinary incontinence.

INTRODUCTION AND HYPOTHESIS: In women with predominant stress urinary incontinence (SUI), recent data are still controversial regarding the short-term outcomes of mini-slings and there is a lack of evidence about the outcomes in the long term. Our aim was to evaluate the long-term effectiveness and complication rates of Altis® (Coloplast). METHODS: A total of 145 women with clinical SUI were implanted with an Altis® sling between April 2012 and December 2015. Women completed the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) before the intervention and in the following consultations. A telephone interview was performed in January 2021 and 131 women (90%) were available for re-evaluation. The main outcome was treatment success, defined as no self-reported SUI symptoms and no reintervention. Secondary outcomes included response to ICIQ-SF (cure defined as ICIQ-SF = 0) and Patient Global Impression of Improvement (PGI-I) questionnaires, de novo overactive bladder (OAB) symptoms and adverse events. RESULTS: The overall treatment success was 73.3% at a median follow-up of 8 years. The ICIQ-SF cure rate was 66.1%. In the PGI-I, 70.4% answered that they were much better or very much better. Later postoperative complications included 2 cases (1.5%) of vaginal extrusion (requiring surgical removal of the eroded mesh segment), 3 (2.3%) cases of infravesical obstruction (which led to sling section), de novo urgency in 20 patients (15.3%), and mild dyspareunia in 2 (1.5%) patients. CONCLUSIONS: The Altis® sling was safe and effective in a long-term follow-up, improving the quality of life in patients with SUI.

TOCSY, hydrogen decoupling and computational calculations to an unequivocal structural elucidation of a new sesquiterpene derivative and identification of other constituents from Praxelis sanctopaulensis.

INTRODUCTION: Praxelis genus comprises 24 species, however, only two species of this genus have been chemically investigated. Here we investigated Praxelis sanctopaulensis, a native plant from Brazil, that occurs mainly in Cerrado regions. OBJECTIVE: The goal was to identify the specialised metabolites from P. sanctopaulensis, and compare with those described from Praxelis and Chromolaena species. METHODS: The phytochemical study of P. sanctopaulensis was performed through different chromatography techniques, including high-performance liquid chromatography (HPLC), gas chromatography flame ionisation detector (GC-FID), and ultra-high-performance liquid chromatography high-resolution tandem mass spectrometry (UHPLC-HRMS/MS). The structures of the compounds were established based on spectroscopic analysis, total correlated spectroscopy (TOCSY), hydrogen decoupling and computational calculations was used to an unequivocal structural elucidation of a new sesquiterpene. The antioxidant activity was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP), and antimicrobial assay was performed by the microdilution method. Comparison of the flavonoids described P. sanctopaulensis was carried out using principal component analysis. RESULTS: The phytochemical investigation of P. sanctopaulensis led to the isolation of a pair of diastereomers, praxilone A and praxilone B. Seven known compounds were isolated from this species, another 14 fatty acids were detected in hexane fraction, and 26 compounds were identified from ethyl acetate fraction. All these compounds are being described for the first time in this species, with the exception of viridifloric acid. The ethyl acetate fraction showed potent antioxidant activity. CONCLUSIONS: Forty-seven compounds are described from P. sanctopaulensis. The combination of different techniques of nuclear magnetic resonance (NMR) spectroscopy and computational calculations allowed the unequivocal structure elucidation of a new cadinene. The clustering analysis showed similarities between the flavonoids identified in P. sanctopaulensis and in Chromolaena species.

Sexual rehabilitation with intracavernous alprostadil after radical prostatectomy: Outcomes from a nursing program.

INTRODUCTION AND OBJECTIVES: Erectile dysfunction (ED) is a common complication after radical prostatectomy that affects quality of life. There are several therapeutic options, including intracavernous alprostadil injections (IAI). However, no specific recommendations have been made on the optimal rehabilitation strategy. In this study we evaluated a sexual rehabilitation program (SRP) with IAI for patients with ED after radical prostatectomy, assessing the rate of compliance and reasons for dropout. METHODS: The sexual rehabilitation program (SRP) was offered to all patients who underwent radical prostatectomy from 1 January 2010 to 31 December 2019. The first consultations were performed by a urology specialist nurse, explaining the IAI procedure and possible complications. The program was considered successful when the patients achieved autonomy in the drug preparation with a good injection technique. A medical consultation was performed at 6 months evaluating the IAI usage and adverse events. In case of dropout, a questionnaire about reasons for dropout was performed. The primary endpoint was the rate of compliance and dropout of the program. Secondary endpoints were the reasons for dropout and adverse events. RESULTS: 340 patients underwent radical prostatectomy at our institution, and 123 patients accepted to participate in the rehabilitation program. A total of 96 patients (78%) successfully completed the SRP, and at 6 months 60 (62.5%) still used IAI. Concerning the reasons for dropping out, the most frequent were the need of injectable therapy and pain. Regarding complications, 17 patients (13.8%) reported pain related to the injection and 1 patient (0.8%) had a priapism, managed with conservative treatment. CONCLUSIONS: Management of post-radical prostatectomy ED by a nursing program achieved good rates of patients' self-injection accomplishment and treatment compliance. Close monitoring for dose adjustment and management of post-injection penile pain is required during the follow-up.

Emergence of colistin resistance genes (mcr-1) in Escherichia coli among widely distributed wild ungulates.

The environment is considered a major reservoir of antimicrobial resistant microorganisms (AMR) and antimicrobial resistance genes (ARG). Colistin, a "last resort" antibiotic, is used for the treatment of severe infections caused by multidrug-resistant Gram-negative bacteria. The global dissemination of mobile colistin resistance genes (mcr) in natural and non-natural environments is a major setback in the fight against antimicrobial resistance. Hitherto, there is a limited number of studies screening this resistance determinant in bacteria from wildlife. In this study, we describe for the first time the detection of plasmid-mediated colistin resistance in Escherichia coli from wild ungulates in Portugal, which are also widely distributed across Europe. This information is critical to identify the importance of ungulates in the dissemination of resistant bacteria, and their corresponding genes, across the environment. Here, 151 resistant-Enterobacteriaceae isolated from 181 samples collected from different wild ungulate species throughout Portugal were screened for mcr genes. Four mcr-1-positive Escherichia coli were detected from four fallow deer individuals that were sampled in the same hunting ground. These four isolates harboured mcr-1-related IncP plasmids belonging to sequencing types ST155, ST533 and ST345 (n = 2), suggesting bacterial and/or plasmid circulation. All mcr-1-positive E. coli also showed other resistance phenotypes, including MDR, including the B1 commensal phylogenetic profile. All mcr-1-positive E. coli show additional resistance phenotypes, including MDR, including the B1 commensal phylogenetic profile. Our findings are upsetting, highlighting the global dissemination of colistin resistance genes in the whole ecosystem, which, under the One Health framework, emphasizes the urgent need for effective implementation of AMR surveillance and control in the human-animal-environment interfaces.

Ten years follow up of first degree relatives of type 1 diabetes patients: presence of autoimmune biomarkers and the progression to diabetes in a retrospective cohort

ABSTRACT Objective: The aim of the study was to assess the autoimmunity in first degrees relatives (FDR) of patients with type 1 diabetes (T1DM) and the progression to T1DM after 10 years of follow up in the Brazilian population. Subjects and methods: Non-diabetic FDR of T1DM patients were interviewed and blood was drawn for autoantibodies measurement (GADA, IA-2A, IAA, ZnT8A). Serum samples were analyzed by standard radioligand binding assays performed at the Federal University of Rio de Janeiro (GADA, IAA and IA2A), and at the Skäne University Hospital, Sweden (ZnT8A). The FDR were interviewed by phone after 10 years to determine if they had developed T1DM. Descriptive statistical analysis was performed and results were described as means and standard deviation (SD). Results: 81 individuals were analyzed. Thirteen subjects had positive autoantibodies associated with T1DM.10 were positive for 1 autoantibody and 3 subjects were positive for multiple autoantibodies (1 of them showed positivity for 2 autoantibodies - GADA, ZnT8A - and the other two were positive for 3 autoantibodies - GADA, IA2A, ZnT8A). The 3 subjects with multiple positive autoantibodies developed T1DM within 10 years. Conclusions: In Brazilian FDR of T1DM patients, the positivity for multiple autoantibodies indicate a greater chance of progression to T1DM, similar to observed in Caucasians. ZnT8A was helpful in the risk assessment for T1DM development.

Ten years follow up of first degree relatives of type 1 diabetes patients: presence of autoimmune biomarkers and the progression to diabetes in a retrospective cohort.

OBJECTIVE: The aim of the study was to assess the autoimmunity in first degrees relatives (FDR) of patients with type 1 diabetes (T1DM) and the progression to T1DM after 10 years of follow up in the Brazilian population. METHODS: Non-diabetic FDR of T1DM patients were interviewed and blood was drawn for autoantibodies measurement (GADA, IA-2A, IAA, ZnT8A). Serum samples were analyzed by standard radioligand binding assays performed at the Federal University of Rio de Janeiro (GADA, IAA and IA2A), and at the Skäne University Hospital, Sweden (ZnT8A). The FDR were interviewed by phone after 10 years to determine if they had developed T1DM. Descriptive statistical analysis was performed and results were described as means and standard deviation (SD). RESULTS: 81 individuals were analyzed. Thirteen subjects had positive autoantibodies associated with T1DM.10 were positive for 1 autoantibody and 3 subjects were positive for multiple autoantibodies (1 of them showed positivity for 2 autoantibodies - GADA, ZnT8A - and the other two were positive for 3 autoantibodies - GADA, IA2A, ZnT8A). The 3 subjects with multiple positive autoantibodies developed T1DM within 10 years. CONCLUSION: In Brazilian FDR of T1DM patients, the positivity for multiple autoantibodies indicate a greater chance of progression to T1DM, similar to observed in Caucasians. ZnT8A was helpful in the risk assessment for T1DM development.

Mucosa-Associated Lymphoid Tissue Lymphoma Involving the Kidney and Renal Pelvis.

Mucosa-associated lymphoid tissue (MALT) lymphomas are a distinctive group of B-cell lymphomas. These lymphomas arise from various anatomic sites and are mainly seen in the gastrointestinal tract, but the primary involvement of the kidney is extremely rare. We report a case of a MALT lymphoma involving the kidney and the renal pelvis. A 56-year-old man presented with a history of hematuria and left flank pain. A computed tomography scan showed a marked tissue densification in the renal sinus, suggesting marked thickening of the urothelium, conditioning deformity of the renal pelvis and calyces. A cystoscopy confirmed a 2-cm papillary lesion on the left lateral aspect of the bladder. The patient underwent laparoscopic radical nephoureterectomy and transurethral bladder resection. The pathological diagnosis was MALT lymphoma in the kidney and urothelial carcinoma of the bladder. The patient was referred to a hematologist and was free of disease at 20 months of follow up without additional treatment.

CINESUS: a discussão de saúde pública na universidade pela ótica do cinema / CINESUS: the discussion of public health at the University through the lens of Cinema

O uso de filmes enquanto estratégia pedagógica para educação em saúde no ensino superior é uma forma efetiva de promover debate e reflexão através de recursos que despertem o interesse entre discentes. Objetivo: Relatar a experiência de uma liga acadêmica de saúde da família e comunidade, vinculada a uma faculdade de medicina de Minas Gerais, ao fazer uso de filmes para propor debates em saúde pública na Universidade, através de um projeto intitulado CineSUS. Métodos: A definição dos filmes e temática de cada evento foi acordada em reuniões semanais da própria liga acadêmica. O evento foi delineado para ocorrer em um anfiteatro. Após a exibição dos filmes, foi reservado um tempo para mediação de um diálogo entre os presentes sobre a temática trabalhada no curta ou longa metragem. O tema de cada evento foi definido com base no Calendário de Saúde, disponibilizado pelo Ministério da Saúde do Brasil. Resultados: O projeto resultou na realização de cinco eventos que contaram com a presença de discentes de cursos da área da saúde e comunidade geral, permitindo abordar, através do diálogo, temáticas relativas à homofobia, criação do Sistema Único de Saúde, cuidado em saúde mental, racismo e violência contra a mulher. Conclusão: Eventos que fazem uso de recursos audiovisuais com subsequente debate sobre a temática abordada no filme permitem o desenvolvimento de um olhar crítico-reflexivo entre os presentes, no que concerne às populações vulneráveis e políticas de saúde pública, bem como para o fomento da luta social para manutenção do Sistema Único de Saúde no Brasil.

The use of movies as a pedagogical strategy for health education in higher education is an effective way to promote debate and reflection through resources that increased the interest in the students. Objective: to report the experience of an Academic League of Family and Community Health, linked to a medical school in Minas Gerais, when making use of movies to propose debates on public health at the University, through a project entitled CineSUS. Methods: The definition of the movies and theme of each event was agreed at weekly meetings of the academic league itself. The event was designed to take place in an amphitheater. After the screening of the movies, a time was reserved for the mediation of a discussion between those present regarding the theme worked on in the short-film or movie. The theme of each event was defined based on the Health Calendar, made available by the Brazilian Ministry of Health. Results: The project resulted in the realization of five events that were attended by students from health courses and the general community, allowing them to address, through dialogue, themes related to homophobia, the creation of the Unified Health System, mental health care, racism and violence against women. Conclusion: Events that make use of audiovisual resources with subsequent debate on the theme addressed in the movie may develop a critical-reflexive view among participants, regarding vulnerable populations and public health policies, as well as to foment the social struggle for the maintenance of the Unified Health System in Brazil.

Adipose tissue-derived stromal/stem cells + cholecalciferol: a pilot study in recent-onset type 1 diabetes patients

ABSTRACT Objective: Adipose tissue-derived stromal/stem cells (ASCs) and vitamin D have immunomodulatory actions that could be useful for type 1 diabetes (T1D). We aimed in this study to investigate the safety and efficacy of ASCs + daily cholecalciferol (VIT D) for 6 months in patients with recent-onset T1D. Materials and methods: In this prospective, dual-center, open trial, patients with recent onset T1D received one dose of allogenic ASC (1 x 106 cells/kg) and cholecalciferol 2,000 UI/day for 6 months (group 1). They were compared to patients who received chol-ecalciferol (group 2) and standard treatment (group 3). Adverse events were recorded; C-peptide (CP), insulin dose and HbA1c were measured at baseline (T0), after 3 (T3) and 6 months (T6). Results: In group 1 (n = 7), adverse events included transient headache (all), mild local reactions (all), tachycardia (n = 4), abdominal cramps (n = 1), thrombophlebitis (n = 4), scotomas (n = 2), and central retinal vein occlusion at T3 (n = 1, resolution at T6). Group 1 had an increase in basal CP (p = 0.018; mean: 40.41+/-40.79 %), without changes in stimulated CP after mixed meal (p = 0.62), from T0 to T6. Basal CP remained stable in groups 2 and 3 (p = 0.58 and p = 0.116, respectively). Group 1 had small insulin requirements (0.31+/- 0.26 UI/kg) without changes at T6 (p = 0.44) and HbA1c decline (p = 0.01). At T6, all patients (100%; n = 7) in group 1 were in honeymoon vs 75% (n = 3/4) and 50% (n = 3/6) in groups 2 and 3, p = 0.01. Conclusions: Allogenic ASC + VIT D without immunosuppression was safe and might have a role in the preservation of β-cells in patients with recent-onset T1D. ClinicalTrials.gov: NCT03920397.
