Toxoplasmic retinochoroiditis (TR) is the most common identifiable cause of posterior uveitis in Brazil. Response to treatment and clinical presentation may vary significantly. We assessed serum levels of brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF), nerve growth factor (NGF), neurotrophin (NT)-3, and NT-4/5 in patients with active TR, before and after TR treatment.
Methods
Twenty patients with active lesion and 15 healthy controls were enrolled in the study. Serum concentration of neurotrophic factors was determined by enzyme-linked immunosorbent assay.Results
BDNF levels were significantly higher in patients before treatment when compared with controls (p = 0.0015). There was no significant difference in pro-BDNF, NGF, GDNF, NT-3, and NT-4/5 levels between TR patients and controls. Treatment did not affect the levels of these factors.Conclusion
BDNF may be released in the context of the active TR inflammatory response. 相似文献2.

Background
Men who have sex with men (MSM) account for the highest prevalence of HIV in Brazil. HIV testing allows to implement preventive measures, reduces transmission, morbidity, and mortality.Methods
We conducted a cross-sectional study to evaluate HIV testing during lifetime, factors associated with the decision to test, knowledge about HIV transmission, and use of condoms between MSM from the city of Natal, northeast Brazil.Results
Out of 99 participants, 62.6% had been tested for HIV during lifetime, 46.2% in the last year. The most frequent reported reason to be tested for HIV infection was curiosity (35.5%). Correct knowledge about HIV was observed in only 9.2% of participants. In multivariate analysis, age (PR 0.95; 95%CI, 0.91–0.99; p = 0.041) and previous syphilis test (PR 4.21; 95%CI, 1.52–11.70; p = 0.006) were associated with HIV testing.Conclusions
The frequency of HIV testing among MSM from Natal is rather low, especially in younger MSM, and knowledge about HIV transmission is inappropriate. 相似文献3.

Introduction
Neuroendocrine tumors (NETs) are rare, but their incidence is rising. Alkylating agents (ALKY), temozolomide and streptozotocin, are the main chemotherapies used for advanced pancreatic NETs. According to retrospective data, O6-methylguanine-DNA methyltransferase (MGMT) status appears to be a predictive factor of the response to ALKY.Aims
The main objective is to evaluate the value of tumor MGMT promoter (pMGMT) methylation in the prediction of the objective response (OR) at 3 months in patients treated with ALKY. Secondly, we will evaluate the value of MGMT immunohistochemistry and the efficacy of treatment with ALKY vs. oxaliplatin-based chemotherapy (Ox).Materials and methods
A national, prospective, open-label, randomized, controlled and multicenter trial was designed. Main inclusion criteria are: adult patients with well-differentiated advanced duodeno-pancreatic, lung, or unknown primitive NETs with a validated indication for chemotherapy. pMGMT methylation will be assessed by pyrosequencing, but an ancillary study will compare this technique with others ones including MGMT immunohistochemistry.Results
A total of 104 patients will be randomly assigned (1:1 for unmethylated or 2:1 for methylated pMGMT NETs) to either the ALKY arm or to the Ox arm.Conclusion
Recruitment started on October 16, 2018 (NCT03217097) and will be open in 21 centers in France. 相似文献4.

Introduction and Objectives
Atopic dermatitis (AD) is the most common cutaneous inflammatory disease in both adults and children. Although emerging therapeutic approaches are being investigated for the management of pediatric AD, it still needs to be managed with conventional treatments. This consensus document is aimed at providing an update on general management and therapies of pediatric AD, defining practical recommendations for using both topical and systemic agents.Material and Methods
A panel of experts consisting of dermatologists and pediatricians were convened in order to define statements, through a Delphi process, standardizing the management of AD in pediatric subjects in a real-world setting.Results
A set of practical recommendations obtaining an at least 75% agreement was presented.Conclusions
This set of practical recommendations represents a simple and fast snapshot on the pediatric use of common anti-AD therapeutics. 相似文献5.

Introduction
New massive sequencing techniques make it possible to determine the composition of airway microbiota in patients with cystic fibrosis (CF). However, the relationship between the composition of lung microbiome and the clinical status of paediatric patients is still not fully understood.Material and methods
A cross-sectional observational study was conducted on induced sputum samples from children with CF and known mutation in the CFTR gene. The bacterial sequences of the 16SrRNA gene were analyzed and their association with various clinical variables studied.Results
Analysis of the 13 samples obtained showed a core microbiome made up of Staphylococcus spp., Streptococcus spp., Rothia spp., Gemella spp. and Granulicatella spp., with a small number of Pseudomonas spp. The cluster of patients with less biodiversity were found to exhibit a greater number of sequences of Staphylococcus spp., mainly Staphylococcus aureus (p 0.009) and a greater degree of lung damage.Conclusion
An airway microbiome with greater biodiversity may be an indicator of less pronounced disease progression, in which case new therapeutic interventions that prevent reduction in non-pathogenic species of the airway microbiota should be studied. 相似文献7.

Background
Sigmoid volvulus is a common cause of colonic obstruction in old and frail patients. Its standard management includes the endoscopic detorsion of the colonic loop, followed by an elective sigmoidectomy to prevent recurrence. However, these patients are often poor candidates for surgery.Aim
The aim of this study was to compare death rate between elective sigmoidectomy and conservative management following endoscopic detorsion for sigmoid volvulus.Methods
The medical records of 83 patients undergoing endoscopic detorsion of a sigmoid volvulus from 2008 to 2014 were retrospectively reviewed. Patients were divided into two groups: ‘elective surgery’ and ‘no surgery’.Results
Patients in the ‘no surgery’ group (n?=?42) were older and had more loss of autonomy than in the ‘elective surgery’ group. Volvulus endoscopic detorsion was successful in 96% of patients with no complications. The median follow-up was 13 months (1 day-67 months). The death rate was 62% in the ‘no surgery’ group versus 32% in the ‘elective surgery’ group (p?=?0.02). In the ‘no surgery’ group, 23/42 of patients had volvulus recurrence. No recurrence occurred after surgery.Conclusion
Elective surgery must be planned as soon as possible after the first episode of sigmoid volvulus. In frail patients, other options must be developed. 相似文献8.

Background
Hepatitis C is an important health problem. In Brazil, 1–2 million people are infected. Despite this expressive number, and the availability of very successful treatment, many patients remained undiagnosed mainly because of the asymptomatic nature of the infection.Objectives
To describe epidemiological characteristics of HCV-infected patients seen at referral centers in Brazil, the source of referral, and the time spanned to reach a reference center, in order to improve the identification of undiagnosed patients.Methods
Multicenter observational, cross-sectional study carried out in 15 centers of Brazil, between January/2016 and June/2017. Data of patients with a confirmed diagnosis (anti-HCV and HCV-RNA) were collected by interview using standard questionnaires and by review of charts.Results
Two thousand patients were included; 55.1% were male, mean age 58 ± 11 years. Only 14.9% had higher education and 84.2% received up to five monthly minimum Brazilian wages (approximately US$260.00/month). The time between diagnosis and beginning of follow-up was 22.9 months. The most common reasons for testing were check-up (33.2%) and blood donation (19%). General practitioners diagnosed most of the patients (30.1%). Fibrosis stage was mainly evaluated by liver biopsy (61.5%) and 31.3% of the patients were cirrhotic at diagnosis.Conclusions
This multicenter Brazilian study showed that the mean time to reach a referral center for treatment was almost two years. Primary care physicians diagnoses most hepatitis C cases in the country. Population campaigns and medical education should be encouraged to intensify screening of asymptomatic individuals, considering the efficiency of check-ups in identifying new patients. 相似文献9.

Background
Anti-TNF therapies infliximab (IFX), adalimumab (ADA), and golimumab (GOL) are approved for treating moderate to severe ulcerative colitis (UC). In UC, only the switch from IFX to ADA has been investigated, reaching no more than 10–43% remission rates at 12 months.Aim
Of the present study was to investigate disease outcome after a switch from subcutaneous (SC) agents to the intravenous (IV) agent (IFX).Methods
In this retrospective multicentre study, we analysed the charts of UC patients unresponsive/intolerant or with secondary loss of response (LOR) to ADA or GOL who were switched to IFX. We evaluated clinical response and remission together with adverse events at 3, 6, and 12 months follow-up.Results
Seventy-six patients were included; 38 patients started ADA and 38 started GOL for a mean therapy duration of 6?±?6 months. Indications for switch were adverse events in 3%, primary failure in 79%, and LOR in 18% of patients. Clinical remission was reached by 47%, 50%, and 77% of patients, respectively. Patients that switched for LOR did numerically, but not statistically, better than patients who switched for primary failure.Conclusions
Our data show a superior remission rate in SC to IV anti-TNF switch in UC compared to the IV to SC switch reported in literature. 相似文献10.
Background
Cholangiocarcinoma (CCA) represents a devastating malignancy characterized by high mortality, and notoriously problematic to diagnose. Recently, microRNAs (miRs) have been intensively investigated due to their potential usefulness from a tumor treatment perspective.Aims
The current study was aimed to investigate whether miR-494 influences epithelial-mesenchymal transition (EMT), tumor growth and metastasis of CCA.Methods
The regulatory miRNAs of WDHD1 in CCA expression chip were predicted, followed by determination of the miR-494 and WDHD1 expression in normal cholangiocyte tissues and CCA tissues. The related protein levels were determined. CCA cell migration, invasion, viability, and cell cycle distribution and the dosage-dependent effect of miR-494 on CCA cell growth were subsequently detected. Finally, tumorigenicity and lymph node metastasis (LNM) were measured.Results
Initially, miR-194 affected the CCA development via negatively regulating WDHD1 and miR-494 which were downregulated while WDHD1 was upregulated in CCA. In addition, miR-494 overexpression elevated E-cadherin expression while decreased expressions of WDHD1, N-cadherin, Vimentin, Snail, Twist and MMP-9. Finally, overexpressed miR-494 was observed to suppress EMT, cell viability, migration, invasion, arrest cell cycle progression, tumor formation, and LNM while accelerating cell apoptosis in vivo.Conclusion
This study indicated that miR-494 overexpression suppresses EMT, tumor formation and LNM while promoting CCA cell apoptosis through inhibiting WDHD1 in CCA. 相似文献11.

Backgound
A significant proportion of hepatitis B surface antigen (HBsAg) negative/anti-hepatitis B core antigen (anti-HBc) positive patients with non-Hodgkin lymphoma (NHL) undergoing rituximab-based chemotherapy (R-CT) may suffer hepatitis B virus (HBV) reactivation.Aims
We wanted to assess efficacy and safety of lamivudine (LMV) prophylaxis to prevent this complication.Methods
Eighty-five consecutive HBsAg negative/anti-HBc positive NHL patients (71 years, 100% serum HBV DNA undetectable, 74% anti-HBs positive) received LMV coadministered with R-CT and for 18 months after the end of R-CT. Serum ALT, HBsAg, anti-HBs and HBV DNA were assessed every 4 months during and after end of LMV.Results
During 39 (2–108) months of study period, including 21 months of LMV and 27 additional months after LMV discontinuation, one patient (2%) had HBV reactivation, 31 months after stopping LMV and during administration of new immunosuppressive regimens, without LMV prophylaxis, owing to incomplete oncological response. A 50% decline of anti-HBs titers occurred in 22/63 (35%) patients, including 12 who became anti-HBs seronegative. Five (6%) patients had ALT increase during R-CT but none required R-CT discontinuation. Seventeen (20%) patients died, all for tumour progression.Conclusion
LMV prophylaxis is safe and effective in preventing HBV reactivation in HBsAg negative/anti-HBc positive NHL patients receiving R-CT. 相似文献12.

Background
In APPRECIA trial, Crohn's disease (CD) patients undergoing intestinal resection were randomized to postoperative adalimumab (ADA) or azathioprine (AZA).Aims
To evaluate health-related quality of life (HRQoL) in APPRECIA trial.Methods
HRQoL was evaluated using disease-specific shortened Spanish version of the IBDQ (SIBDQ-9) and generic European Quality of Life-5 Dimensions (EQ-5D) questionnaires, completed at baseline and at weeks 24 and 52.Results
Sixty-one patients (37 ADA and 24 AZA) had evaluable data for HRQoL. Patients treated with ADA or AZA had significant improvement from baseline to weeks 24 and 52 in SIBDQ-9 and EQ-5D (p?<?0.001 and p?≤?0.006 for all comparisons, respectively). There were no differences between treatment arms in mean change in SIBDQ-9 and EQ-5D at weeks 24 and 52 vs baseline. Only patients without endoscopic recurrence had significant improvement in SIBDQ-9 (p?<?0.001) and EQ-5D (p?<?0.001) at week 52. At week 52, there was a high to moderate negative correlation between CDAI score with SIBDQ-9 score (Pearson’s r: ?0.768) and with EQ-5D index (r: ?0.644).Conclusion
HRQoL improved after intestinal resection in CD, irrespective of the postoperative therapy used (ADA or AZA). Outcomes in HRQoL were associated with prevention of endoscopic recurrence, since improvements in HRQoL were only significant in patients with endoscopic remission at 1 year. 相似文献13.

Background
The long-term management of perianal Crohn’s disease for patients on anti-TNF-α therapy remains challenging.Aim
To evaluate the long-term course and complications of patients with perianal fistulas treated with anti-TNF-α based on their clinical remission and healing on MRI.Methods
Patients were evaluated clinically and by MRI. Deep remission was defined as clinical remission associated with the absence of contrast enhancement and T2 hyperintensity on MRI. Flare-free survival, surgery and hospitalizations were compared based on the presence or not of deep remission.Results
Forty-eight consecutive patients were included with a median follow-up of 62?months after anti-TNF-α first administration. Deep remission was observed in 16 patients (33.4%). For patients in deep remission, the median time to any perianal event was 116?months (95–130) versus 42?months (8–72) in patients with pathological MRI (p?<?0.001). Sixteen patients (50%) with pathological MRI had perianal surgery versus 2 (12.5%) in the deep remission group (p?<?0.05). The mean duration of cumulative hospital stays was 0.75?±?0.52?days in the deep remission group versus 19.7?±?7.4 in the pathological group (p?<?0.05).Conclusions
Higher flare-free survival and lower rates of surgery and hospitalization were found in patients achieving deep remission. 相似文献14.

Individuals with diabetes develop lower extremity amputation for several reasons. Investigations into pathways to the development of complications are important both for treatment and prevention.
Aim
To evaluate the relationship between amputation and risk factors in people with diabetes mellitus.Materials and method
All participants included in this study (n = 165) were recruited from the Diabetic Foot Program, developed in a Brazilian University, over seven years (2007–2014) and all information for this study was extracted from their clinical records.Results
The prevalence of amputation in patients with diabetes with four risk factors was up to 20% higher when compared to those with only one risk factor. The main predictive risk factors for amputation in this population were the presence of an ulcer and smoking.Conclusion
The risk factors for amputation can be predicted for people with diabetes mellitus and, in the present study, the main factors were the presence of an ulcer and the smoking habit. 相似文献15.

Background
Chronic hepatitis B virus (HBV) infection remains a primary cause of morbidity and mortality worldwide.Aim
The study is aimed at updating the clinical and epidemiological profile of chronic HBV infection in Italy.Methods
A cross-sectional multicenter prospective study enrolled consecutive HBsAg positive patients seen in 73 Italian centers in the period 2012–2015. Individual patient data were collected using an electronic platform and analyzed using standard statistical methods.Results
Among 2877 HBsAg positive individuals (median age 49.8?years, 68% males), 27% were non-Italian natives (NINs); 20% had chronic infection, 58.5% chronic hepatitis and 21.5% cirrhosis. Among NINs, age was younger, male gender was less prevalent and liver disease less advanced than in Italians (all p?<?0.0001). HBeAg positive cases were 23.6% among NINs vs 8.2% in Italians (p?<?0.0001); HDV coinfections 11.1% vs 7.3% (p?=?0.006) and HCV coinfections 2.3% vs 4.2% (p?=?0.017), respectively. Anti-HDV or anti-HCV antibodies were detected more frequently in patients with cirrhosis. Fifty percent of NINs with cirrhosis were aged below 45?years.Conclusion
The study offers an insight into the evolving burden of chronic hepatitis B virus infection in the near future and highlights new territories for public health interventions. 相似文献18.
Background
Murine models have been widely used in the study of allergy as sensitized mice can produce IgE and/or IgG1in response after the injection of an antigen/adjuvant combination. Ailanthus altissima pollen (AAP) has been recently reported as an emerging aeroallergen in Iran. So far, several AAP candidate allergens by the screening of allergen-specific IgE in the sera from AAP sensitized patients in Iran.Objective
The aim of the present study was to detect and compare the allergens eliciting an IgE response in a mouse model, and in human, using pollen extract of A. altissima and an immunoproteomics based approach.Methods
The pollen proteins were extracted in phosphate-buffered saline (PBS). Thirty male BALB/c mice were randomly divided into two groups of AP extract sensitized and sham that respectively received AAP PBS extract and a PBS control by intraperitoneal injections at regular intervals. The optimized AAP protein extracts were analyzed using 2D-gel electrophoresis and were subsequently confronted to pooled sera of sensitized mice.Results
Two-D gel electrophoresis of AAP extract allowed the separation of 125 protein spots distributed in a wide range of pI and molecular masses. Two-DE immunoblotting using pooled sera of sensitized mice led to the detection of 14 IgE reactive spots with molecular masses ranging from 12 to 40–42 kDa.Conclusion
The results do not correlate with our previous analyses using human AAP-sensitized sera. These findings reflect some differences in the sIgE reactivity to allergenic proteins in animal models. 相似文献19.

Introduction
Dilated cardiomyopathy (DCM) is a disease of the heart muscle characterized by ventricular dilatation and impaired systolic function. Familial forms account for 30-50% of cases. Autosomal dominant inheritance is the predominant pattern of transmission. Causal genetic variants have been identified in several genes and molecular diagnosis has implications for genetic counseling and risk stratification.Objective
We aimed to estimate the frequency of genetic variants and the molecular basis of DCM in Portugal.Methods
We performed a multicenter study of unrelated patients, recruited between 2013 and 2014. Variants in 15 genes were screened using PCR with direct sequencing (next-generation sequencing with at least 30-fold coverage combined with Sanger sequencing).Results
A total of 107 patients were included, 64 (60%) men, mean age at diagnosis 38±13 years, with 48 (45%) familial cases. In total, 31 rare variants in eight genes (mainly in MYBPC3, TNNT2 and LMNA) were identified, in 28 patients (26%). Only four variants had been previously described in association with DCM, 11 with hypertrophic cardiomyopathy, and nine variants were novel. Four variants were likely pathogenic and the remainder were of uncertain significance. We found no major differences in the main clinical and imaging characteristics between patients with or without rare variants and patients with likely pathogenic variants.Conclusions
Our results reflect the complexity and diversity of DCM genetics. For better interpretation of the pathogenicity of the variants found and their causative roles in DCM, molecular cascade screening of families is imperative. Further insight into genotype-phenotype correlations and risk stratification is desirable. 相似文献20.
