ABSTRACT

INTRODUÇÃO: Dados de estudos randomizados avaliando os efeitos a longo prazo da cirurgia bariátrica no controle e remissão da hipertensão (HTN) são escassos. O seguimento de curto e médio prazo do Estudo GATEWAY (1 e 3 anos) mostrou melhora significativa e remissão da hipertensão após a cirurgia bariátrica. Aqui, apresentamos os dados de acompanhamento de 5 anos deste estudo. MÉTODOS: Conduzimos um ensaio clínico randomizado, em um centro único, fase III, paralelo e aberto. Pacientes com obesidade graus 1 e 2, tomando no mínimo 2 medicamentos anti-hipertensivos em doses máximas para hipertensão, foram alocados aleatoriamente para Bypass gástrico em Y de Roux (RYGB) combinado com tratamento clínico (TC) ou TC (estilo de vida/aconselhamento nutricional) isoladamente. O desfecho primário foi a redução de pelo menos 30% do total de anti-hipertensivos, mantendo níveis controlados de pressão arterial (PA) <140/90mmHg. A análise principal seguiu o princípio de intenção de tratar modificada e os valores ausentes foram imputados com a técnica de imputação múltipla. Os desfechos secundários incluíram vários biomarcadores. RESULTADOS: Foram incluídos 100 pacientes (76% mulheres, idade: 43,8±9,2 anos, índice de massa corporal, IMC: 36,9±2,7Kg/ m2). Após 5 anos, o IMC foi de 27,8±3,8kg/m2 para RYGB e 36,4±3,9kg/m2 para TC (P<0,001). A análise de sensibilidade considerando apenas os casos com seguimento concluído (n=69) revelou resultados consistentes. Os desfechos secundários nos grupos RYGB e TC, aos 60 meses, foram: circunferência abdominal 88,05 ± 9,84cm e 109,44 ± 9,76cm (P<0,001) ; hemoglobina glicada 5,4 ± 0,43% e 5,96 ± 0,9% (P<0,001); insulina 6,41 ± 2,46mU/L e 24,65 ± 16,57mU/L (P<0,001); LDL colesterol 93.61 ± 31.06mg/dL e 109.94 ± 37.58mg/dL (P=0,022); triglicerídeos 86,76 ± 38,45mg/dL e 140,33 ± 59,11 mg/dL (P<0,001); proteína C reativa de alta sensibilidade 0,81 ± 0,76mg/L e 6,13 ± 6,22mg/L (P=0,005), respectivamente. CONCLUSÕES: A cirurgia bariátrica é uma estratégia eficaz e duradoura no controle da PA com menor número ou nenhum medicamento anti-hipertensivo e na melhora do perfil metabólico e inflamatório em pacientes com obesidade graus 1 ou 2 e hipertensão.

ABSTRACT

OBJECTIVES: This study aimed to evaluate the influence of thickness and opacity on the ability of composite resin and ceramic veneer restorations to mask discolored teeth. METHODS: Ninety veneers were made of lithium disilicate ceramic, shades BL1 and 0 (IPS e.max Press, Ivoclar Vivadent), and 60 were made of composite resin, shade BL-L (IPS Empress Direct, Ivoclar Vivadent). The veneers measured 4 mm in width x 4 mm in length and had a thickness of 0.7, 1.0, or 1.2 mm. One hundred and fifty human premolars were selected to obtain 150 dental fragments with the following dimensions: 4 mm x 4 mm x 3 mm (width x length x thickness). The fragments were discolored, submitted to color measurement and randomly assigned to 15 groups (n=10) according to the type and opacity of the restorative material (IPS e.max Press: high translucency [HT], low translucency [LT], and medium opacity [MO]; IPS Empress Direct: dentin and enamel) and thickness of the veneers (0.7, 1.0, and 1.2 mm). After cementation of the ceramic or composite resin veneers using a translucent resin cement (RelyX veneer, 3M), a final color measurement was taken from each specimen and the total color variation (ΔE) was calculated by subtracting the initial and the final color measurement. The final lightness (L*) of the restored dental fragments was also calculated. RESULTS: The highest ΔE values were observed for the LT and MO ceramic groups, followed by dentin composite resin. Regarding the different thicknesses of ceramic veneers, every 1.2-mm-thick group had higher values of ΔE, considering their respective opacities (p<0.05). The highest lightness values were found for the LT and MO ceramic veneers (thickness of 1.2 mm). Dentin-shade composite resins showed similar lightness values in all groups. CONCLUSION: The best thickness/opacity combinations for masking discolored dental substrates were LT and MO ceramic veneers with 1.2-mm thickness. Dentin-shade composite resin veneers with a thickness of 0.7-1.0 mm showed good ability to mask discolored dental substrates.

ABSTRACT

Meniscal tears account for approximately 15% of all knee injuries and almost 25% of them require surgical procedures. Magnetic Resonance Imaging (MRI) is widely used for noninvasive assessment of the knee joint and is considered reliable and a powerful tool for the detection of soft tissue injuries of the knee. The aim of the study was to evaluate the sensitivity, specificity, and accuracy of magnetic resonance imaging (MRI) to predict the meniscal tears repair in sports practitioners. 104 incoming consecutive patients who underwent knee joint ligament reconstruction and/or arthroscopy for the treatment of meniscal injury at knee joint were imaged using a 1.5-T MRI scanner prior to arthroscopy. MRI images were evaluated for anterior cruciate ligament (ACL), articular cartilage, and meniscal injury. Images were correlated with arthroscopic findings, used as the gold standard. The sensitivity, specificity, and accuracy of MRI in predicting meniscal repair were 61.1%, 65.94%, and 64.58%, respectively. The agreement between MRI and arthroscopy yielded a kappa index of 0.236, indicating fair agreement. When the menisci were evaluated separately, 65.85% sensitivity, 45.45% specificity, and 54.16% accuracy were found for the medial meniscus, while 46.15%, 79.51%, and 75.0% for the lateral meniscus, respectively. The accuracy was 62.09% in whose patients that arthroscopy was performed up to 3 months after MRI and 67.18% in those that this time frame was more than 3 months before surgery. The 54 meniscal injuries occurred more frequently in the posterior horn; most injuries had a longitudinal pattern and were located in the red-red (vascular) zone. We suggest that magnetic resonance imaging is only moderately accurate for the prediction of meniscus reparability.

ABSTRACT

Infection caused by the fungus Batrachochytrium dendrobatidis (Bd) produces chytridiomycosis, a disease considered one of the main causes of amphibian population declines in the world. In Brazil, Bd has been recorded in several regions, but mainly in the Atlantic Forest biome. This study aimed to investigate the occurrence of Bd in amphibian species in Bahia State to test the hypothesis that Bd is widespread in other Brazilian biomes. Using histological analysis, we evaluated the skin of 190 anurans of 85 species preserved in herpetological collections. Based on these analyses, the distribution of Bd was extended approximately 400 km to the west, 150 km to the north and 105 km to the east in the state of Bahia. Of the 190 specimens analyzed, Bd infection was diagnosed in 16 individuals, from 14 species, with the earliest record from a specimen collected in 1996 in the Caatinga biome. We identified Bd in 13 adult specimens, including 2 individuals showing suggestive signs of the disease (loss of skin pigmentation). In tadpoles, we recorded fungal structures in the oral region and on the epidermis adjacent to the rows of teeth. The results of this study corroborate the prediction that Bd is widespread in the Atlantic Forest biome, and suggest that it is widespread in the other biomes of the state (Cerrado and Caatinga, at least since 1996). Conservation efforts should involve long-term studies aimed at providing information on the dynamics of the infection, its relationship with its host and its effect on amphibian populations.

ABSTRACT

Background Complex percutaneous coronary intervention (PCI) is associated with higher ischemic risk, which can be mitigated by long-term dual antiplatelet therapy (DAPT). However, concomitant high bleeding risk (HBR) may be present, making it unclear whether short- or long-term DAPT should be prioritized. Objectives This study investigated the effects of ischemic (by PCI complexity) and bleeding (by PRECISE-DAPT [PRE dicting bleeding Complications in patients undergoing stent Implantation and Sub sequent Dual Anti Platelet Therapy] score) risks on clinical outcomes and on the impact of DAPT duration after coronary stenting. Methods Complex PCI was defined as ≥3 stents implanted and/or ≥3 lesions treated, bifurcation stenting and/or stent length >60 mm, and/or chronic total occlusion revascularization. Ischemic and bleeding outcomes in high (≥25) or non-high (<25) PRECISE-DAPT strata were evaluated based on randomly allocated duration of DAPT. Results Among 14,963 patients from 8 randomized trials, 3,118 underwent complex PCI and experienced a higher rate of ischemic, but not bleeding, events. Long-term DAPT in non-HBR patients reduced ischemic events in both complex (absolute risk difference: −3.86%; 95% confidence interval: −7.71 to +0.06) and noncomplex PCI strata (absolute risk difference: −1.14%; 95% confidence interval: −2.26 to −0.02), but not among HBR patients, regardless of complex PCI features. The bleeding risk according to the Thrombolysis In Myocardial Infarction scale was increased by long-term DAPT only in HBR patients, regardless of PCI complexity. Conclusions Patients who underwent complex PCI had a higher risk of ischemic events, but benefitted from long-term DAPT only if HBR features were not present. These data suggested that when concordant, bleeding, more than ischemic risk, should inform decision-making on the duration of DAPT. (AU)

ABSTRACT

PURPOSE: Evaluate the main etiologies and clinical characteristics of male urethral stricture disease (USD) in Brazil. METHODS: This multicentric study was performed using retrospective data collected from six Brazilian referral centers of urethral reconstruction. The database comprised data from 899 patients with USD who had undergone surgical treatment from 2008 to 2018. Age, stricture site and primary stricture etiology were identified for each patient. RESULTS: The mean age was 52.13 ± 16.9 years. The most common etiology was iatrogenic (43.4%), followed by idiopathic (21.7%), trauma (21.5%) and inflammatory (13.7%). Of the iatrogenic causes, 59% were secondary to urethral instrumentation (60% by urethral catheterization and 40% by transurethral procedures), 24.8% by other procedures (prostatectomy, radiotherapy, postectomy) and 16.2% by failed hypospadia repairs. Pelvic fracture urethral distraction injuries were responsible for most of the trauma-related strictures (62.7%). When stratified by age, the most common stricture etiology was trauma in the 0-39 years old group (42.8%), idiopathic in the 40-59 years old group (32.4%) and iatrogenic in patients over 60 years old (68%). In regard to the stricture site, 80% presented with an anterior urethral stricture and 20% with a posterior stenosis. In the anterior stenosis group, the most common stricture site was bulbar (39.5%). CONCLUSION: In Brazil, as in many developed countries, the most common cause of urethral stricture diseases is iatrogenic, especially urethral catheterization. These findings emphasize the need of a careful urethral manipulation and a better training of healthcare professionals. Trauma is still responsible for a great proportion of strictures and inflammatory etiologies are now less frequently observed.

ABSTRACT

BACKGROUND: Limb-sparing surgery in locally advanced soft tissue sarcomas (LA STS) is challenging. The aim of this study is to evaluate upfront isolated limb perfusion (ILP) in untreated patients with LA STS. METHODS: All consecutive patients with LA STS of the limbs deemed borderline or unresectable and treated with upfront ILP as induction treatment between 2003 and 2016 were included. Demographic, clinical and long-term characteristics were obtained and retrospectively analyzed. RESULTS: 41 patients (pts), with a median age of 51 years [range 21-76], were identified (lower limb 68%, upper limb 32%). Liposarcoma and undifferentiated pleomorphic sarcoma were the most common subtypes (27% and 22%, respectively). Acute toxicities, using Wieberdink classification, were grade II (35 pts, 85%), grade III (2 pts, 5%) and no grade IV-V. Local control rate was 98%. 32 pts had limb-sparing surgery (78%). 1 pt had an early amputation due to progressive disease after ILP. 8 pts were not operated (four had RT alone, one had distant metastases, two had a complete response and one died 3 months after ILP of a pulmonary embolism). 36 pts (84%) received postoperative RT. After a median follow-up of 43 months, 18 pts (47%) relapsed. Median disease-free survival (DFS) was 6.7 years. The median overall survival (OS) was not reached. The 1-year, 5-year and 10-year DFS and OS rates were, respectively, 75%, 50% and 45%, and 90%, 63% and 55%. CONCLUSION: Upfront ILP is an efficient and well-tolerated limb-sparing procedure in borderline or unresectable LA STS without hampering OS.

ABSTRACT

Objective The objective of this study was to compare demographic data, clinical/laboratorial features and disease activity at diagnosis in three different groups with distinct time intervals between onset of signs/symptoms and disease diagnosis. Methods A multicenter study was performed in 1555 childhood-onset systemic lupus erythematosus (American College of Rheumatology criteria) patients from 27 pediatric rheumatology services. Patients were divided into three childhood-onset systemic lupus erythematosus groups: A: short time interval to diagnosis (<1 month); B: intermediate time interval (≥1 and <3 months); and C: long time interval (≥3 months). An investigator meeting was held to define the protocol. Demographic data, SLICC classification criteria and SLEDAI-2 K were evaluated. Results The number of patients in each group was: A = 60 (4%); B = 522 (33.5%); and C = 973 (62.5%). The median age at diagnosis (11.1 (4.2-17) vs. 12 (1.9-17.7) vs. 12.5 (3-18) years, P = 0.025) was significantly lower in group A compared with groups B and C. The median number of diagnostic criteria according to SLICC (7 (4-12) vs. 6 (4-13) vs. 6 (4-12), P < 0.0001) and SLEDAI-2 K (18 (6-57) vs. 16 (2-63) vs. 13 (1-49), P < 0.0001) were significantly higher in group A than the other two groups. The frequency of oral ulcers in the palate (25% vs. 15% vs. 11%, P = 0.003), pleuritis (25% vs. 24% vs. 14%, P < 0.0001), nephritis (52% vs. 47% vs. 40%, P = 0.009), neuropsychiatric manifestations (22% vs. 13% vs. 10%, P = 0.008), thrombocytopenia (32% vs. 18% vs. 19%, P = 0.037), leucopenia/lymphopenia (65% vs. 46% vs. 40%, P < 0.0001) and anti-dsDNA antibodies (79% vs. 66% vs. 61%, P = 0.01) were significantly higher in group A compared with the other groups. In contrast, group C had a less severe disease characterized by higher frequencies of synovitis (61% vs. 66% vs. 71%, P = 0.032) and lower frequencies of serositis (37% vs. 33% vs. 25%, P = 0.002), proteinuria >500 mg/day (48% vs. 45% vs. 36%, P = 0.002) and low complement levels (81% vs. 81% vs. 71%, P < 0.0001) compared with groups A or B. Conclusions Our large Brazilian multicenter study demonstrated that for most childhood-onset systemic lupus erythematosus patients, diagnosis is delayed probably due to mild disease onset. Conversely, the minority has a very short time interval to diagnosis and a presentation with a more severe and active multisystemic condition.

ABSTRACT

Immune checkpoint blockers (ICB) have become pivotal therapies in the clinical armamentarium against metastatic melanoma (MMel). Given the frequency of immune related adverse events and increasing use of ICB, predictors of response to CTLA-4 and/or PD-1 blockade represent unmet clinical needs. Using a systems biology-based approach to an assessment of 779 paired blood and tumor markers in 37 stage III MMel patients, we analyzed association between blood immune parameters and the functional immune reactivity of tumor-infiltrating cells after ex vivo exposure to ICB. Based on this assay, we retrospectively observed, in eight cohorts enrolling 190 MMel patients treated with ipilimumab, that PD-L1 expression on peripheral T cells was prognostic on overall and progression-free survival. Moreover, detectable CD137 on circulating CD8+ T cells was associated with the disease-free status of resected stage III MMel patients after adjuvant ipilimumab + nivolumab (but not nivolumab alone). These biomarkers should be validated in prospective trials in MMel.The clinical management of metastatic melanoma requires predictors of the response to checkpoint blockade. Here, the authors use immunological assays to identify potential prognostic/predictive biomarkers in circulating blood cells and in tumor-infiltrating lymphocytes from patients with resected stage III melanoma.

ABSTRACT

Human leukocyte antigen-G (HLA-G) presents inhibitory functions in immune cells and is located in a chromosomal region associated with systemic lupus erythematosus (SLE) susceptibility. Polymorphisms in 3' untranslated region (3'UTR) of HLA-G gene may influence protein expression. To date, no study analyzing HLA-G polymorphism and expression in childhood-onset systemic lupus erythematosus (cSLE) has been conducted. Therefore, we investigated the influence of HLA-G 3'UTR polymorphisms in 50 cSLE patients and 144 healthy controls. For the expression analysis, the control group included 26 healthy individuals. No significant difference in allele, genotype, and haplotype frequencies was observed between patients and control group. However, both the 14 bp deletion allele (odds ratio [OR] = 2.76, 95% confidence interval [CI] = 1.17-6.52, P = .028) and the 14 bp deletion-deletion genotype (OR = 8.00, 95% CI = 1.57-40.65, P = .006) showed an association with lupus nephritis. After Bonferroni correction, none P-value remained statistically significant. Regarding HLA-G expression, no significant difference was observed between plasma levels of cSLE patients (56.02 U/mL, interquartile range [IQR] = 37.54-75.41) and control group (49.2 U/mL, IQR = 27.84-154.4, P = .952). However, when the patients were stratified according to clinical manifestations, patients with hematological manifestations showed a lower plasma concentration of soluble HLA-G (sHLA-G) (47.08 U/mL, IQR = 34.15-61.56) than patients with no hematological manifestations (65.26 U/mL, IQR = 47.69-102.60, P = .013). These results suggest that HLA-G polymorphism has small effect on cSLE susceptibility and that sHLA-G may be involved in the pathogenesis of the disease.

ABSTRACT

Childhood-onset systemic lupus erythematosus (cSLE) exhibits an aggressive clinical phenotype and severe complications. This could be due to a pro-inflammatory cytokine milieu. Therefore, we determined plasma levels of Th1 (IL-2, IFN-γ, TNF), Th2 (IL-4), Th17 (IL-17A, IL-6), and Treg (IL-10) cytokines in a cohort of cSLE patients and healthy controls, and we evaluated the association between these cytokines and disease activity. We conducted a cross-sectional study with 51 cSLE patients from two pediatric rheumatology services. Ten cSLE patients participated in a longitudinal follow-up study. Blood samples were collected from the same patient during active and inactive disease. Disease activity was evaluated according to SLE Disease Activity Index 2000 (SLEDAI-2K). Cytokines levels were measured by cytometric bead array technique. cSLE patients had higher IL-6 (P<0.001) and IL-10 (P<0.001) levels than healthy controls. Patients with active disease had higher IL-6 and IL-10 levels than patients with inactive disease (P=0.001 and P=0.014, respectively) and the control group (both P<0.001). IL-6 (P=0.022), IL-10 (P=0.013), and IL-17A (P=0.041) levels were significantly higher during active than inactive disease. Linear regression analysis revealed IL-6 (P=0.002, 95%CI=0.006-0.025) and IL-10 (P=0.01 95%CI=0.021-0.150) as independent factors for increased SLEDAI-2K. IL-6, IL-10, and IL-17A are candidate biomarkers for disease activity in cSLE patients. This is the first longitudinal study to support their pivotal role in the pathogenesis of the disease.

ABSTRACT

PURPOSE: There are only scarce data on the place of brachytherapy (BT) for treatment of vulvar carcinoma. Our institutional experience of interstitial BT for vulvar carcinoma patients is reported. METHODS AND MATERIALS: Clinical records of patients receiving low-dose-rate or pulsed-dose-rate BT as part of the primary treatment for primary/recurrent vulvar squamous cell carcinoma or as part of postoperative treatment between 2000 and 2015 were included. Patients, tumors, and treatment characteristics as well as clinical outcome were examined. RESULTS: A total of 26 patients treated with BT were identified. BT was delivered as part of primary intent treatment for locally advanced/recurrent cancer in 11 patients and as part of postoperative treatment in 15 patients. Median age at time of BT was 63 years (range, 41-88 years). Pulsed-dose-rate and low-dose-rate were used in 15 patients and 11 patients, respectively. BT was performed as a boost to the tumor bed following external beam radiotherapy (n = 13) or as the sole irradiation modality (n = 13). Total median dose at the level of primary tumor was 60 GyEQD2 (range, 55-60 GyEQD2). With mean followup of 41 months (range, 5 months-11.3 years), 11 patients experienced tumor relapse, and in two of them, site of relapse was only local. Three-year estimated disease-free survival and overall survival rates were 57% (95% confidence interval: 45-69%) and 81% (95% confidence interval: 72-90%), respectively. All toxicities were Grade 2 or less. CONCLUSIONS: Interstitial BT used as part of the primary or postoperative treatment of vulvar carcinoma is feasible with a satisfactory toxicity profile. Prognosis remains, however, dismal, with a high frequency of failures in patients with locally advanced tumors.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the effect of low-thickness ceramic laminate translucency on water sorption and solubility in resin luting agents. METHODS AND MATERIALS: Ceramic slides (15×0.7 mm) were generated using lithium disilicate (IPS e.max Press, Ivoclar-Vivadent, Schaan, Liechtenstein) that were A1 in color and had decreasing degrees of translucency (high, medium, and low). A slide of transparent glass of similar size was used as the control. Under each slide, 15 specimens (8×0.5 mm) of differing composite materials from the same manufacturer (3M ESPE Dental Products, St Paul, MN, USA) were prepared (n=5): light-cured resin cement (RelyX Veneer); dual-cured resin cement (RelyX ARC); and flowable composite (Z350XT Flow). To evaluate the loss or gain of mass, the specimens were dried until a constant mass was reached. Then, they were immersed in water for seven days and weighed immediately following removal from water. Subsequently, the specimens were dried again until a constant mass was obtained. The mass measurements were used to calculate the water sorption and solubility. Statistical analyses were carried out using a two-way analysis of variance and the Tukey test. RESULTS: Under the high-translucency ceramic slides, all of the luting agents showed similar performance regarding water sorption; the flowable composite resin and the light-cured resin cement had the lowest solubility values. Under the medium- and low-translucency surfaces, the dual-cured resin cement and the flowable composite resin showed better performance with respect to water sorption and solubility. CONCLUSIONS: In the case of high-translucency laminates, luting agents with different activation methods might be used. However, even in thin sections, decreasing the translucency of the laminate led to significant loss of light penetration, indicating a decreased likelihood of the physical activation of the resin cement.
