    We report the development of a PCR-single strand conformation polymorphism (SSCP) method to identify Prototheca spp. responsible for bovine mastitis: P. zopfii and P. blaschkeae. The method was set up using reference strains belonging to P. zopfii genotype 1, P. zopfii genotype 2, and P. blaschkeae as target species and P. stagnora, and P. ulmea as negative controls. The assay was applied on 50 isolates of Prototheca spp. isolated from bovine mastitic milk or bulk-tank milk samples, and all isolates were identified as P. zopfii genotype 2. We conclude that the described PCR-SSCP approach is accurate, inexpensive, and highly suitable for the identification of P. zopfii genotype 2 on field isolates but also directly on milk, if preceded by a specific DNA extraction method

    Inflammation is associated with atrial fibrillation (AF), but little is known about the association of AF with the inflammatory serum cytokines after the acute postoperative phase. Thus, we aimed to explore how plasma cytokines concentrations modify during a 3-week cardiac rehabilitation after heart surgery, comparing patients who developed postoperative AF (POAF) and those with permanent AF with patients free from AF (NoAF group). We enrolled 100 consecutive patients and 40 healthy volunteers as a control group. At the beginning of cardiac rehabilitation, 11 days after surgery, serum levels of MPO, PTX3, ADAM17, sST2, IL-25, and IL-33 were dramatically higher, whereas TNFa and IL-37 levels were much lower in NoAF, POAF, and permanent AF patients than in the healthy volunteers. After rehabilitation, most of the cytokines changed tending towards normalization. POAF patients (35% of the total) had higher body mass index and abdominal adiposity than NoAF patients, but similar general characteristics and risk factors for POAF. However, ADAM-17 and IL-25 were always lower in POAF than in NoAF patients, suggesting a protective role of IL-25 and ADAM 17 against POAF occurrence. This finding could impact on therapeutic strategies focusing on the postoperative prophylactic antiarrhythmic interventions

    The efficacy of cardiac rehabilitation in heart-failure patients who received a left-ventricular assist device (LVAD) instead of heart transplantation (HTx) is still unclear. This study aims to evaluate whether cardiac rehabilitation is beneficial in LVAD as HTx patients in the short term and whether its effects in LVAD patients persist over time. Twenty-five LVAD patients were evaluated by functional and psychological tests at admission (T0) and discharge (T1) of a 4-week inpatient structured rehabilitation program, and follow-ups 3 (T2), 6 (T3), and 12 months (T4) after discharge. Twenty-five matched HTx patients were also studied from T0 to T1 to compare the improvements in the six-minute walk test (6MWT). The quality-of-life scores substantially improved in LVAD patients and the 6MWT showed the same functional recovery as in HTx patients from T0 to T1. After T1, numerous LVAD patients withdrew from the study. However, the 6MWT outcome increased further from T1 to T3, with a positive trend during the follow-ups. Hemoglobin and the ventilatory performance increased, and the psychological perception of heart-failure symptoms and pain further improved at T2. In conclusion, exercise-based rehabilitation programs provide similar beneficial effects in LVAD and HTx patients, without deterioration in LVAD patients up to 12 months after discharge

    Elderly hypertensive patients: Silent white matter lesions, blood pressure variability, baroreflex impairment and cognitive deterioration

    Introduction: Hypertension may increase the risk for stroke and is frequently associated with subcortical and periventricular white matter lesions (WML). This is considered a prognostic factor for the development of stroke and cognitive impairment, particularly in attention processes. Additionally, in elderly subjects, it is known the implications of alterations in the neural cardiovascular regulation and the cardiovascular risk. Aims: To evaluate, in asymptomatic elderly hypertensives, the association of ambulatory blood pressure values and autonomic activity with neurocognitive impairment and WML. In addition, we also evaluated the role of the autonomic nervous system particularly the vagal component, in the pathogenesis of white matter lesions. Methods: We studied 22 elderly essential hypertensive patients (69±1.1y) and as control group, 16 normotensive elderly subjects (age 67±3.2y) were also enrolled. To each one of them, a cerebral MRI was performed to classify them, by a neuro-radiologist blinded of the subject clinical status, using a 0 to 9 scale where 0 denoted no WML and 9 the most severe lesions. Twenty four hours arterial blood pressure monitoring was performed to each one of the subjects under study. Office blood pressure was measured 3 times and the mean value reported. Beat to beat finger arterial pressure monitoring (Finapres) was performed for a 2h period. During the first hour the patient remained lying supine in a quiet darkened room and during the second hour four manoeuvres: stand-up, cold pressor test, handgrip and quiet activity were randomly performed. Mean blood pressure and pulse interval values, from the two periods, and their respective variabilities, baroreflex sensitivity and power spectral analysis were calculated. Regarding neuropsychological assessment: Minimental test, attention evaluation, RAVLT, visual memory, language and executive function, geriatric depression scale, cognitive deficit rate tests were performed in all subject. Results: We found a closer correlation of WML with 24hs ABPM than with office BP readings being more evident with systolic blood pressure during the night time period. WML failed to show any correlation with SBP average values derived from the Finapres recordings in either the supine or the upright position, while it was positively and significantly related to PP in both conditions. However, beat to beat SBP variability, either in the supine or in the upright position, showed a positive and significant correlation with WML. During the resting period, BRS calculated through the sequence method (Time Domain) was similar in HT and NT subjects. However when BRS was assessed in the frequency domain a significant reduction was observed in HT compared with NT. In addition, At the time of laboratory manoeuvres implying sympathetic activation, BRS was significantly reduced as compared to the resting values being particularly evident for the HF values. In hypertensive subjects, only semantic fluency showed a significant difference (p=0.01), when compared to normotensives. When the patients were divided in older and younger than 75 years, a significant difference was observed in the delayed analysis of words, and in the phonological fluency showing a significant higher rate of pathological results in the group of patients older than 75 years. Conclusions: As previously shown, incidental WML, suggestive of silent cerebrovascular disease, is a frequent finding in elderly hypertensives. Night-time BP mean values and SBP variability in upright position seems to be the best predictor on silent cerebral WML. The vagal component of the autonomic nervous system seems to be involved in the pathogenesis of these lesions. Finally, the neurocognitive alterations are multifactorial in origin where the aging process seems to be the principal component.Fil: Ramírez, Agustín José. Fundación Favaloro; Argentina.

    Researchers\u2019 interest have recently moved toward the identification of recurrent psychopathological profiles characterized by concurrent elevations on different behavioural and emotional traits. This new strategy turned to be useful in terms of diagnosis and outcome prediction. We used a person-centred statistical approach to examine whether different groups could be identified in a referred sample and in a general-population sample of children and adolescents, and we investigated their relation to DSM-IV diagnoses. A latent class analysis (LCA) was performed on the Child Behaviour Checklist (CBCL) syndrome scales of the referred sample (N = 1225), of the general-population sample (N = 3418), and of the total sample. Models estimating 1-class through 5-class solutions were compared and agreement in the classification of subjects was evaluated. Chi square analyses, a logistic regression, and a multinomial logistic regression analysis were used to investigate the relations between classes and diagnoses. In the two samples and in the total sample, the best-fitting models were 4-class solutions. The identified classes were Internalizing Problems (15.68%), Severe Dysregulated (7.82%), Attention/Hyperactivity (10.19%), and Low Problems (66.32%). Subsequent analyses indicated a significant relationship between diagnoses and classes as well as a main association between the severe dysregulated class and comorbidity. Our data suggested the presence of four different psychopathological profiles related to different outcomes in terms of psychopathological diagnoses. In particular, our results underline the presence of a profile characterized by severe emotional and behavioural dysregulation that is mostly associated with the presence of multiple diagnosis
