Listeria monocytogenes infection in pregnant women and newborns is a cause for serious concern, and invasive disease outcome strongly depends on prompt antibiotic therapy. To provide sooner identification from neonatal bacteremia we performed a CAMP test directly on positive blood aliquots and inoculated the Liofilchem® O.A. Listeria chromogenic agar as well, thus providing a 24-h turn-around time for response. 相似文献
Objective: To provide clinicians and researchers information regarding (1) the existing outcome measures to assess the loss of functionality in the activities of daily living (ADLs) of patients with stroke and (2) the presence of these assessment tools in the Italian context.
Study Design and Setting: For this Systematic Review Medline, CINAHL, and PsycINFO were searched for articles published up to 4 July 2017. Two authors independently identified eligible studies on the basis of prede?ned inclusion criteria and extracted data. Study quality and risk of bias were assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.
Results: Of 370 publications identified and screened, 46 studies fell within the inclusion criteria and were critically reviewed. The most commonly used tools were: the Frenchay Activities Index and the Functional Independence Measure.
Conclusion: This review has emphasized the need for agreement among researchers as to which tool must be studied in depth or adapted to other national contexts in order to develop universal norms and standards. 相似文献
Morphometric MRI studies in adult patients with migraine have consistently demonstrated atrophy of several gray matter (GM) regions involved in pain processing. We explored the regional distribution of GM and white matter (WM) abnormalities in pediatric patients with episodic migraine and their correlations with disease clinical manifestations. Using a 3.0 T scanner, brain T2-weighted and 3D T1-weighted scans were acquired from 12 pediatric migraine patients and 15 age-matched healthy controls. GM and WM volumetric abnormalities were estimated using voxel-based morphometry (p < 0.05, family-wise error corrected). Compared to controls, pediatric migraine patients experienced a significant GM atrophy of several regions of the frontal and temporal lobes which are part of the pain-processing network. They also had an increased volume of the right putamen. The left fusiform gyrus had an increased volume in patients with aura compared to patients without aura and controls, whereas it was significantly atrophied in patients without aura when compared to the other two groups. No abnormalities of WM volume were detected. In migraine patients, regional GM atrophy was not correlated with disease duration and attack frequency, whereas a negative correlation was found between increased volume of the putamen and disease duration (r = ?0.95, p < 0.05). These results show that GM morphometric abnormalities do occur in pediatric patients with migraine. The presence of such abnormalities early in the disease course, and the absence of correlation with patient clinical characteristics suggest that they may represent a phenotypic biomarker of this condition. 相似文献
Sickle cell disease (SCD) is a monogenic hemoglobinopathy associated with significant morbidity and mortality. Cardiopulmonary, vascular and sudden death are the reasons for the majority of young adult mortality in SCD. To better understand the clinical importance of multi‐level vascular dysfunction, in 2009 we assessed cardiac function including tricuspid regurgitant jet velocity (TRV), tissue velocity in systole(S′) and diastole (E′), inflammatory, rheologic and hemolytic biomarkers as predictors of mortality in patients with SCD. With up to 9 years of follow up, we determined survival in 95 children, adolescents and adults with SCD. Thirty‐eight patients (40%) were less than 21 years old at initial evaluation. Survival and Cox proportional‐hazards analysis were performed. There was 19% mortality in our cohort, with median age at death of 35 years. In the pediatric subset, there was 11% mortality during the follow up period. The causes of death included cardiovascular and pulmonary complications in addition to other end‐organ failure. On Cox proportional‐hazards analysis, our model predicts that a 0.1 m/s increase in TRV increases risk of mortality 3%, 1 cm/s increase in S′ results in a 91% increase, and 1 cm/s decrease in E′ results in a 43% increase in mortality. While excluding cardiac parameters, higher plasma free hemoglobin was significantly associated with risk of mortality (p=.049). In conclusion, elevated TRV and altered markers of cardiac systolic and diastolic function predict mortality in a cohort of adolescents and young adult patients with SCD. These predictors should be considered when counseling cardiovascular risk and therapeutic optimization at transition to adult providers. 相似文献
Maturity-Onset Diabetes of the Young type 4 is a rare form of diabetes mellitus, caused by mutations in the PDX1 gene. However, only a few mutations in this gene have been associated as a cause of monogenic diabetes up to date. It makes difficult to create a clinical manifestation profile of this disease and, consequently, to improve the therapeutic management for these patients. Here we report a normal weight woman, diagnosed with diabetes mellitus at 27 years old, during her first pregnancy. At the time of the recruitment, she was 40 years old and had a body mass index of 23.9 kg/m2, glycated hemoglobin level of 9.6%, and fasting plasma glucose (FPG) of 254 mg/dL. She presented no diabetic complications and she was being treated with insulin. She reported a family history of diabetes mellitus characteristic of an autosomal dominant mode of inheritance. Molecular analysis of the PDX1 gene revealed the missense variant c.532G > A (p.(Glu178Lys)) segregating from the patient to her son, reported as diabetic. It was absent in her healthy daughter. The c.532G > A seems to be a rare variant, absent in human variants databases, and among 86 normoglycemic controls. Eight in silico algorithms classified this variant as probably pathogenic. Additionally, analysis of the evolutionary conservation showed the glutamic acid in the position 178 of PDX-1 protein as conserved among several species. Our findings reinforce the importance of screening rare MODY genes among families with suspicion of monogenic diabetes to help better understand the clinical manifestations of this disease. 相似文献
