Objective
Higher serum melatonin levels have previously been found in patients with severe sepsis who died within 30 days of diagnosis than in survivors. The objective of our study were to determine whether serum melatonin levels during the first seven days of severe sepsis diagnosis could be associated with sepsis severity and mortality.Methods
Multicentre study in eight Spanish Intensive Care Units which enrolled 308 patients with severe sepsis. We determined serum levels of melatonin, malondialdehyde (as biomarker of lipid peroxidation) and tumor necrosis factor-alpha at days 1, 4 and 8 of severe sepsis diagnosis. The study's primary endpoint was 30-day mortality.Results
A total of 103 patients had died and 205 survived at 30 days of severe sepsis diagnosis, with the non-survivors presenting higher serum melatonin levels at days 1 (p < 0.001), 4 (p < 0.001) and 8 (p < 0.001) of severe sepsis diagnosis than the survivor patient group. The multiple logistic regression analysis found that serum melatonin levels at days 1, 4 and 8 of severe sepsis diagnosis (p < 0.001, p = 0.01 and p = 0.001, respectively) were associated with mortality adjusted for age, serum lactic acid, SOFA score and diabetes mellitus.Conclusions
The novel and more interesting findings of our study were that serum melatonin levels during the first seven days of severe sepsis diagnosis are associated with sepsis severity and mortality. 相似文献3.

Introduction
Allergic diseases have become an increasingly common reality in the last years, extending beyond the family context.Objective
Assessing the level of knowledge on asthma, food allergies and anaphylaxis of asthmatic children's parents/caregivers (PC), elementary school teachers (EST) and university students (US) in Uruguaiana, RS, Brazil.Method
577 individuals (PC – N = 111; EST – N = 177; US – N = 299) took part in the study, answering the Newcastle Asthma Knowledge Questionnaire (validated for Portuguese) and another questionnaire on Food Allergy (FA) and anaphylaxis.Results
Although PC have asthmatic children, their asthma knowledge level was average, slightly above that of EST and EU. The lack of knowledge on passive smoking, use of medications and their side effects should be highlighted. US have shown to be better informed about FA and anaphylaxis. However, even though a significant proportion of respondents know the most common symptoms of FA and anaphylaxis, few named subcutaneous adrenaline as the drug of choice for treating anaphylaxis. Although a significant number of respondents know about the possibility of anaphylactic reactions happening at school or in activities outside the school, we were surprised by the absence of conditions in schools to provide emergency care to such students.Conclusion
Despite the high prevalence of allergic diseases in childhood, asthmatic children's parents/caregivers, elementary school teachers and university students have inadequate levels of knowledge to monitor these patients. 相似文献5.

Objectives
This study aims to investigate the antimicrobial and the anti-biofilm activities of Lactobacillus plantarum extract (LPE) against a panel of oral Staphylococcus aureus (n = 9) and S. aureus ATCC 25923. The in vitro ability of LPE to modulate bacterial resistance to tetracycline, benzalchonium chloride, and chlorhexidine were tested also.Methods
The minimum inhibitory concentrations (MICs) and the minimal bactericidal concentrations of Lactobacillus plantarum extract, tetracycline, benzalchonium chloride and clohrhexidine were determined in absence and in presence of a sub-MIC doses of LPE (1/2 MIC). In addition, the LPE potential to inhibit biofilm formation was assessed by microtiter plate and atomic force microscopy assays. Statistical analysis was performed on SPSS v. 17.0 software using Friedman test and Wilcoxon signed ranks test. These tests were used to assess inter-group difference (p < 0.05).Results
Our results revealed that LPE exhibited a significant antimicrobial and anti-biofilm activities against the tested strains. A synergistic effect of LPEs and drug susceptibility was observed with a 2–8-fold reduction.Conclusion
LPE may be considered to have resistance-modifying activity. A more detailed investigation is necessary to determine the active compound responsible for therapeutic and disinfectant modulation. 相似文献6.

Objectives
Corynebacterium spp. are becoming recognized as pathogens that potentially cause various infections. We aimed to evaluate the clinical characteristics associated with Corynebacterium spp. bacteremia.Patients and methods
We retrospectively reviewed the medical records of all adult patients who had positive blood cultures for Corynebacterium spp. in a single university hospital between January 2014 and December 2016. Patients were divided into a bacteremia group and a contamination group based on microbiological test results and clinical characteristics. Patients’ characteristics, antimicrobial susceptibility of isolated species, antimicrobials administered, and patient outcomes were evaluated.Results
Corynebacterium spp. were isolated from blood samples of 63 patients; Corynebacterium striatum was the predominant isolate. Twenty-eight patients were determined to have bacteremia. Younger age (p = 0.023), shorter time to positivity (p = 0.006), longer hospital stay (p = 0.009), and presence of an indwelling vascular catheter (p = 0.002) were observed more often in the bacteremia group compared to the contamination group. The source of infection in most patients with bacteremia was an intravenous catheter. All tested strains were susceptible to vancomycin. Four of the 27 patients with bacteremia died, despite administration of appropriate antimicrobial therapy.Conclusions
We found that younger age, shorter time to positivity, and presence of an indwelling catheter were related to bacteremia caused by Corynebacterium spp. Appropriate antimicrobials should be administered once Corynebacterium spp. are isolated from the blood and bacteremia is suspected. 相似文献7.

Objectives
To determine the factors associated with Mycobacterium tuberculosis complex-positive blood culture.Methods
Case-control study. Sociodemographic, clinical and laboratory data were collected from 2000 to 2015.Results
We reviewed medical records of 533 patients with culture-proven tuberculosis, of whom 27.2% (145/533) had blood culture available. Patients with mycobacteremia presented more frequently with abdominal tuberculosis, body mass index <18 kg/m2, and had lower hemoglobin and albumin levels. No differences were observed regarding HIV status.Conclusions
Few studies have reported on the characteristics associated with Mycobacterium tuberculosis complex bacteremia, especially among Human Immunodeficiency Virus-negative patients. Out of 145 tuberculosis-infected patients with blood culture results available, 21 turned out positive. Anemia, hypoalbuminemia, and a body mass index < 18 kg/m2 were associated with mycobacteremia. 相似文献8.

Introduction
Lady Windermere syndrome (LWS) is a pulmonary disease caused by Mycobacterium avium complex (MAC). The objective of this study is to ascertain its frequency and characteristics in the northern area of the autonomous community of Castile and León.Methods
A retrospective study of patients with MAC isolates in respiratory samples from five public hospitals in the autonomous community over a six-year period, following the ATS/IDSA criteria. The MAC strains were identified by GenoType Mycobacterium reverse hybridisation probes or PCR-RFLP analysis of the hsp65 gene.Results
Of 183 cases of MAC identified, only five women (2.7%) aged 68.8 ± 10.7 years met LWS criteria. In three cases, MAC was isolated jointly and intermittently with other pathogens. Only one patient was treated according to ATS/IDSA criteria.Discussion
LWS remains underestimated, with affected patients representing a significant burden on healthcare resources over long periods of time. As a result, greater microbiological and therapeutic knowledge of the syndrome is needed. 相似文献9.

Introduction
Treatment of multidrug-resistant Gram-positive infections caused by Staphylococcus aureus remains as a clinical challenge due to emergence of new resistance mechanisms. Tedizolid is a next-generation oxazolidinone, recently approved for skin and soft tissues infections. We conducted a study to determine in vitro susceptibility to vancomycin, daptomycin, linezolid and tedizolid in MRSA clinical isolates from adult patients with skin and soft tissue infections.Material and methods
Methicillin-resistant S. aureus isolates were collected in three tertiary-care hospitals of Medellin, Colombia, from February 2008 to June 2010 as part of a previous study. Clinical characteristics were assessed by medical records and MIC values were determined by Epsilometer test. Genotypic analysis included spa typing, MLST, and SCCmec typing.Results
A total of 150 MRSA isolates were evaluated and tedizolid MIC values obtained showed higher in vitro activity than other antimicrobials, with MIC values ranging from 0.13 μg/mL to 0.75 μg/mL and lower values of MIC50 and MIC90 (0.38 μg/mL and 0.5 μg/mL). In contrast, vancomycin and linezolid had higher MIC values, which ranged from 0.5 μg/mL to 2.0 μg/mL and from 0.38 μg/mL to 4.0 μg/mL, respectively. Tedizolid MICs were 2- to 5-fold lower than those of linezolid. Clinical characteristics showed high previous antimicrobial use and hospitalization history. The majority of the strains belong to the CC8 harboring the SCCmec IVc and were associated with the spa t1610 (29.33%, n = 44).Conclusion
In vitro effectiveness of tedizolid was superior for isolates from skin and soft tissue infections in comparison with the other antibiotics evaluated. The above added to its less toxicity, good bioavailability, daily dose and unnecessity of dosage adjustment, make tedizolid in a promising alternative for the treatment of infections caused by MRSA. 相似文献10.

Background
A progressive decrease in Helicobacter pylori eradication rates has been described over the years, driving the need for new antibiotic treatments.Aim
To evaluate the efficacy and safety of the addition of rifaximin (Spiraxin®) to standard triple therapy (omeprazole, amoxicillin and clarithromycin) for the eradication of H. pylori.Methods
Independent prospective clinical trial (EUDRACT no.: 2013-001080-23). Forty consecutive adult patients were included with H. pylori infection, dyspeptic symptoms and naive to eradication treatment. A full blood test was performed in the first five patients enrolled to evaluate the safety of the treatment. H. pylori eradication was confirmed with the 13C-urea breath test at least four weeks after the end of treatment with rifaximin 400 mg/8 h, clarithromycin 500 mg/12 h, amoxicillin 1 g/12 h and omeprazole 20 mg/12 h for 10 days.Results
Forty patients were consecutively enrolled, 53% woman, mean age 44 years. Indication for eradication: 60% non-investigated dyspepsia, 38% functional dyspepsia and 2% gastric ulcer. Four patients did not attend the eradication confirmatory breath test. The eradication rate was 61% (95% CI: 45–77%) for the protocol and 55% (40–70%) for intention-to-treat. About 76% of the patients experienced adverse events (35% diarrhea, 14% nausea and 24% metallic taste), none of which was serious. The blood tests did not show significant alterations.Conclusion
Acceptable H. pylori eradication rates are not achieved with rifaximin associated with standard triple therapy for 10 days. 相似文献11.

Background
Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) is spreading worldwide, but little is known about the epidemiology of this pathogen in Brazil.Objective
To evaluate clinical and microbiological features of children with S. aureus infections admitted to a university hospital.Methods
This was a cross-sectional study evaluating the potential risk factors for CA-MRSA, and a retrospective cohort evaluating in-hospital clinical outcomes. To include patients with both community and hospital-associated infections, we screened the results of the microbiological laboratory tests from January 1, 2012, to December 31, 2016. According to the phenotype, we classified the isolates in Methicillin-Susceptible S. aureus (MSSA), Hospital-Associated Methicillin-Resistant S. aureus (HA-MRSA), and CA-MRSA. Clinical data were collected from the patients’ medical records.Results
We identified 279 cases of S. aureus infections (MSSA = 163, CA-MRSA = 69, HA-MRSA = 41). Overall, the incidence density of CA-MRSA and MSSA infections increased while the HA-MRSA incidence density decreased over the study period. CA-MRSA infected patients were more likely to present with skin and soft tissue infections (OR: 2.83, 95%CI: 1.54–5.33, p < 0.001) and osteomyelitis (OR: 4.76; 95%CI: 1.16–22.71, p = 0.014) when compared to MSSA and HA-MRSA infections. Unadjusted case fatality rates were similar between MSSA-infected patients (3.14%, 5/159) and CA-MRSA infected patients (3.80%, 3/79, p = 0.792), while HA-MRSA infected patients were more likely to die in the hospital (12.20%, 5/41, p = 0.013).Conclusions
CA-MRSA is an emergent pediatric pathogen in Brazil. Our results highlight the relevance of choosing an appropriate initial antimicrobial drug for treating children with severe S. aureus infections. 相似文献12.

Background
Assessment of volume status and differentiating “underfill” and “overfill” edema is essential in the management of patients with nephrotic syndrome (NS).Objectives
Our aim was to evaluate the volume status of NS patients by using different methods and to investigate the utility of bioelectrical impedance analysis (BIA) in children with NS.Methods
The hydration status of 19 patients with NS (before treatment of NS and at remission) and 25 healthy controls was assessed by multifrequency BIA, serum N-terminal-pro-brain natriuretic peptide (NT-proBNP) levels, inferior vena cava (IVC) diameter, left atrium diameter (LAD) and vasoactive hormones.Results
Renin, aldosterone levels, IVC diameter and LAD were not statistically different between the groups. NT-proBNP values were statistically higher in the attack period compared to remission and the control group (p = 0.005 for each). Total body water (TBW), overhydration (OH) and extracellular water (ECW) estimated by the BIA measurement in the attack group was significantly higher than that of the remission group and controls. There were no significant correlations among volume indicators in group I and group II. However, significant correlations were observed between NT-proBNP and TBW/BSA (p = 0.008), ECW/BSA (p = 0.003) and ECW/ICW (p = 0.023) in the healthy group. TBW was found to be higher in patients with NS in association with increased ECW but without any change in ICW. NT-proBNP values were higher in patients during acute attack than during remission.Conclusions
Our findings support the lack of hypovolaemia in NS during acute attack. In addition, BIA is an easy-to-perform method for use in routine clinical practice to determine hydration status in patients with NS. 相似文献13.

Aims
Due to the diversity of the Chinese population, it requires considerable research to evaluate HbA1c diagnostic threshold for diagnosis of hyperglycemia.Methods
We included 7909 subjects aged ≥15 without known diabetes from the baseline of Pudong community cohort in 2013. Participants took oral glucose tolerance test (OGTT) and HbA1c assay. Receiver operating characteristic curve determined the HbA1c threshold in the diagnosis of hyperglycemia.Results
The optimal HbA1C threshold for diagnosing newly diagnosed diabetes (NDD) and pre-diabetes in this population was 6.0% (AUC = 0.798, 95%CI: 0.779–0.818) and 5.6% (AUC = 0.655, 95%CI: 0.638–0.671). When compared with elderly age group (≥70 years), HbA1c for detecting NDD performed better in youth (15–39 years: P = 0.003, 40–49 years: P < 0.001). There were 13.81% and 13.34% of participants would be newly detected as NDD and pre-diabetes via HbA1c criteria; meanwhile 3.20% and 15.52% diagnosed as NDD and pre-diabetes by OGTT criteria would be missed diagnosis.Conclusions
The optimal HbA1c thresholds for NDD and pre-diabetes were lower than ADA criteria. It is necessary to carefully consider whether choose HbA1c as a diagnostic criterion or combine two diagnostic standards. Age-specific diagnostic thresholds should be considered when HbA1c was recommended as diagnostic standard. 相似文献14.

Purpose
To determine the prevalence of depression and related risk factors among type 2 diabetes mellitus patients (T2DM) in Jazan area, Saudi Arabia.Method
A cross sectional, self-administered questionnaire study was conducted among T2DM patients in Jazan area, Saudi Arabia. A total of 385 patients were selected at randomly. The Patient Health Questionnaire (PHQ-9) was utilized to measure symptoms and signs of depression.Results
The overall prevalence of depression among T2DM patients was 37.6%. Of them, 24.2% were mildly depressed, 9.6% were moderately severely depressed, and 4.2% were severely depression. Significant predictors of depression include the presence of diabetic foot (P = 0.000), cardio-vascular diseases (P = 0.000), eye complication (P = 0.073), and erectile dysfunction (P = 0.090). The prevalence of depression was not significantly associated with the age (P = 0.375) and gender (P = 0.374). Similarly no association was found with duration of diabetes (P = 0.475) and HbA1c (P = 0.555).Conclusion
The study revealed that diabetes complications are strong predictors of the rate of depression among T2DM patients. Therefore, early depression screening is needed to improve the quality of life of diabetic patients. 相似文献15.

Background
Perinatally HIV-infected children are surviving into adulthood, and getting pregnant. There is a scarcity of information on health and pregnancy outcomes in these women.Aim
To evaluate characteristics related to HIV disease and pregnancy outcomes in perinatally infected women, and to compare these women with a group of youth with behaviorally acquired HIV-infection, at a reference hospital in Rio de Janeiro, Brazil.Methods
A cohort study. Epidemiological, clinical, and laboratory data were compared between perinatally (PHIV) and behaviorally HIV-infected (BHIV) pregnant youth with the primary aim to study pregnancy outcomes in the PHIV group and compare with outcomes to BHIV group.Results
Thirty-two pregnancies occurred in PHIV group, and 595 in BHIV group. A total of seven (22%) PHIV women and 64 (11%) BHIV women had a premature delivery (p = 0.04), however, when adjusting for younger age at pregnancy, and antiretroviral therapy initiation in 1st trimester of pregnancy (OR = 18.66, 95%CI = 5.52–63.14), the difference was no longer significant. No cases of mother-to-child HIV transmission (MTCT) were observed in the PHIV group while there was a 2% MTCT rate in BHIV group.Conclusion
Pregnancy among PHIV was as safe as among BHIV. The differences between those groups were probably related to treatment and prolonged care in the first group. 相似文献16.

Introduction
The commonly held notion that a rural environment decreases the frequency of allergic diseases has proven to be inconsistent amongst children.Objective
Our objective was to contrast the prevalence of bronchial asthma (BA), allergic rhinitis (AR), and atopic dermatitis (AD) between children that live in a rural environment and those that live in urban areas.Methods
We carried out a cross-sectional study amongst children aged six to seven; they were selected through probabilistic, stratified and conglomerated sampling. The prevalence of BA, AR, and AD was identified with the use of the questionnaire provided by The International Study of Asthma and Allergies in Childhood, additionally, we inquired about each child's family history of atopy, their exposure to farm animals, the intake of unpasteurised cow's milk, and the number of siblings related to every child. We used logistic regression and multivariate analysis to determine the correlation between asthma, allergic diseases, and rural environment.Results
We included 189/1003 (18.8%) children from a rural environment, and 814/1003 (81.2%) from an urban area. BA and AR were associated to a family history of atopy (OR = 2.15, p = 0.001; OR = 2.58, p = 0.002, respectively). BA was more prevalent in males (OR = 1.92, p = 0.007). Notably, a higher number of siblings seems to protect against AR (OR = 0.45, p = 0.008). A paternal history of allergies was associated to AD.Conclusions
In our study, we were unable to find protective factors in a rural environment that might decrease the prevalence of asthma or allergic diseases. 相似文献17.

Introduction
Immune response to vaccination in infants born prematurely may be lower than in infants born at full-term. Some clinical factors might be associated with humoral immune response.Objectives
The objectives of this study were to compare the immune response to measles and varicella vaccination in infants born prematurely with those born at full-term and to analyze factors associated with measles and varicella antibody levels.Methods
Prospective study including two groups of infants aged 12 months. One group of infants born prematurely with birth-weight <1500 g and who were in follow-up at the outpatient clinic for preterm infants at the institution and other group of infants born at full-term. Infants with malformations, primary immunodeficiency diseases, born to HIV-positive mothers or who had received plasma or immunoglobulin transfusions five months before or three weeks after vaccination were excluded. Plasma antibodies were measured by ELISA and factors associated with antibody levels were assessed by linear regression.Results
Sixty-five premature and 56 full-term infants were included. The percentage of immune individuals after vaccination against measles (100% vs. 100%) and varicella (92.5% vs. 93.2%) were similar in both groups, as well as the antibody levels against measles (2.393 vs. 2.412 UI/mL; p = 0.970) and varicella (0.551 vs. 0.399 UI/mL; p = 0.114). Use of antenatal corticosteroids decreased measles antibody levels whereas breastfeeding for more than six months increased varicella antibody levels.Conclusions
Humoral responses to measles and varicella were similar between infants born prematurely and full-term infants. Measles antibody levels were negatively associated with antenatal corticosteroid use; varicella antibodies were positively associated with prolonged breastfeeding. 相似文献18.

Background
Antiretroviral therapy (ART) saved millions from HIV-1 infection and AIDS, but some patients do not experience adequate CD4+ T cells gain despite achieving viral suppression. The genetic component of this condition is not yet completely elucidated.Objective
To identify predictive genetic markers of immune response to ART.Methods
Case–control study. Out of 176 HIV-infected patients recruited in the city of Recife, Northeast Brazil, 67 patients with no immunologic response were the cases and the remaining 109 patients who responded were the controls. A set of 94 selected single nucleotide polymorphisms (SNPs) involved in antiretroviral drugs pharmacodynamic pathways and immune system homeostasis were genotyped, while the remaining 48 were ancestry informative markers (AIMs) for controlling for eventual hidden population structure.Results
Male patients were overrepresented in non-responder group (p = 0.01). Non-responders also started with lower absolute CD4+ T cell counts (p < 0.001). We found five SNPs significantly associated with the outcome, being three more frequent in non-responders than responders: rs2243250 (IL4) A allele (p = 0.04), rs1128503 (ABCB1) A allele (p = 0.03) and rs707265 (CYP2B6) A allele (p = 0.02), whereas the other two were less frequent in non-responders: rs2069762 (IL2) C allele (p = 0.004) and rs4646437 (CYP3A4) A allele (p = 0.04).Conclusion
Some significant univariate associations remained independently associated at multivariate survival analysis modeling, such as pre-treatment CD4+ T cells counts, IL2 and ABCB1 genotypes, and use of protease inhibitors, yielding a predictive model for the probability for immune response. More studies are needed to unravel the genetic basis of ART immunological non-response. 相似文献19.

Introduction
Our objectives were to describe the incidence, clinical characteristics, and risk factors for Clostridium difficile infection (CDI) in critically ill patients and to determine C. difficile PCR-ribotypes.Methods
Prospective, observational study in 26 Spanish ICUs. Patients with diarrhea meeting ESCMID criteria for CDI were included. Molecular characterization of isolates was performed using PCR ribotyping.Results
Of 4258 patients admitted to the ICUs, 190 (4.5%) developed diarrhea. Only 16 patients (8.4%) were diagnosed with CDI. Ribotype 078/126 (25.0%) was the most frequently identified. The mortality rate was similar in patients with ICD compared to patients with diarrhea not caused by C. difficile (p = 0.115). Chronic renal insufficiency was identified as the only factor independently associated with the development of CDI (OR 5.87, 95% CI 1.24–27.83; p = 0.026).Conclusions
The incidence of CDI in Spanish ICUs is low. Only chronic renal insufficiency was observed to be a risk factor for CDI development. 相似文献20.
