RESUMO

INTRODUCTION: Cladribine is an oral immune reconstitution therapy for relapsing multiple sclerosis (RMS). Hormonal and immune changes are responsible for the decline of disease activity in the third trimester of pregnancy and disease reactivation in the early post-partum period.We investigate the impact of pregnancy on disease activity in women with MS who conceived after cladribine treatment. METHODS: We recruited women of childbearing age with relapsing-remitting MS (RRMS) who became pregnant or not after being treated with cladribine. For both groups, demographic, clinical and radiological data were collected 1 year before and after treatment during a mean follow-up of 3.53 years. We compared disease activity over time between groups using variance analysis for repeated measures. RESULTS: 48 childbearing women were included. 25 women had a pregnancy after a mean of 1.75 years from the first treatment cycle. Women with or without pregnancy did not differ in demographics or pre-cladribine disease activity. No significant differences in disease activity or EDSS worsening were found between women with or without pregnancy. DISCUSSION: Our findings suggest that pregnancy does not appear to influence disease activity and disability in women previously treated with cladribine; further studies with larger numbers and longer follow-up are needed to confirm this finding.

RESUMO

BACKGROUND: Congenital cytomegalovirus (CMV) infection is the leading infectious cause of neurological impairment for which, currently, there are no approved antenatal treatment options. OBJECTIVES: The aim of this article was to summarize the available evidence on the use of valacyclovir during pregnancy to prevent and treat congenital CMV infection and disease. SOURCES: Two databases (PubMed and ClinicalTrial.gov) were reviewed. CONTENT: Six relevant documents were identified, namely one observational study, three clinical trials, two case reports. Most relevant findings were those from two clinical trials. A phase 2/3 placebo-controlled study showed a decrease of 71% (5 of 45 vs 14 of 47) in rate of CMV vertical transmission in women treated with 8 g/day valacyclovir following primary CMV infection in pregnancy. A phase 2, single-arm clinical trial, showed that 8 g/day valacyclovir administered to mothers of symptomatic infected foetuses increased the portion of asymptomatic neonates to 82% (34 of 41), compared with 43% (20 of 47) in untreated pregnancies from a historical cohort. IMPLICATIONS: Studies in favour of using valacyclovir during pregnancy for prevention and treatment of congenital CMV infection are emerging but are still few. Randomized clinical trials on large cohorts of patients investigating the efficacy on prevention and treatment of congenital CMV are required. Unfortunately, this will be probably not be feasible at least in the short period. In the meantime, data on the 'off label' use of valacyclovir for CMV in pregnancy could be collected within a multicentre observational study.

RESUMO

BACKGROUND: Nowadays, serodiscordant couples (SDCs) with human immunodeficiency virus (HIV) or hepatitis C virus (HCV)-infected men have the chance to conceive safely, giving birth with a minimum risk of cross-infection. OBJECTIVE: To assess the impact of male HIV and HCV infection on the assisted reproductive technologies (ART) outcomes in SDCs, with HIV or HCV seropositive men and negative partners. MATERIALS AND METHODS: Of 153 couples: 24 in Group 1 (HIV-seropositive men), 60 in Group 2 (HCV-seropositive men) and 69 in Group 3 (controls). Sperm-washing procedure was performed using a three-step system. Fresh ICSI cycles were carried out in HIV SDCs, HCV SDCs and controls. Seminal parameters, fertilization rate (FR), cleavage rate (CR), pregnancy rate per cycle (PR/C), miscarriage rate, implantation rate (IR) and live birth rate were evaluated. RESULTS: All the seropositive men have undetectable viral loads at the time of insemination, and both partners were free from co-morbid infections. The median number of embryos transferred was 2.0 (IQR 1.0-3.0), with no differences among groups. FR was significantly reduced in HIV and HCV SDCs compared to the controls (66%, 61% and 75%, respectively; p < 0.01). CR was similar between groups (p = 0.3). IR was 12.1%, 11.1% and 14.1%, respectively, in the three groups (p = 0.30). PR/C was 21.7%, 17.6% and 20.2% in HIV, HCV and controls, respectively. Live birth rate per cycle was 17.4%, 15.7% and 15.9%, respectively. There were no significant differences in clinical pregnancies per cycle, as well as miscarriages and live births (p = 0.30; 0.30; 0.60, respectively). CONCLUSIONS: The sperm-washing technique with ICSI may generate a promising way to improve pregnancy outcomes and to reduce the risk of viral transmission in these couples. In this setting, we can correctly counsel HIV- and HCV-infected men of SDCs with regard to the likelihood of father their own biological child.

RESUMO

Hospital malnutrition is becoming a clinical concern. Our aim was to determine the prevalence of hospital malnutrition through Nutritional Risk Screening 2002 (NRS) and to evaluate nutritional risk through a prospective study. Nutritional status was assessed collecting anthropometric parameters together with the data relating to the diseases in the medical records of patients admitted to the Department of Emergency Medicine of the "Sant'Eugenio" Hospital. One hundred and sixty patients were retrospectively enrolled during a 3-month observational period. The risk of malnutrition was detected in 52% of patients (of whom 38% at risk and 62% at serious risk). The NRS score was positively correlated with patient age, days between hospital admission and nutritional assessment, disease severity, length of hospital stay and catabolism (p less than 0.05); Basal Energy Expenditure (BEE) and mean arm circumference (MUAC) were negatively correlated with positive outcome (p less than 0.05). No correlations were found in the NRS score, gender, height, weight, Body Mass Index (BMI) and Total Energetic Expenditure (TEE) (p=n.s). A high prevalence of the risk of malnutrition may be detected in the emergency medicine setting, particularly in the geriatric population. The NRS score is not strictly related to BMI, but rather is an excellent tool for disease prognosis, as well as nutritional screening.

RESUMO

Nickel acts as cofactor for a number of enzymes of many bacteria species. Its homeostasis is ensured by proteins working as ion efflux or accumulation systems. These mechanisms are also generally adopted to counteract life-threatening high extra-cellular Ni2+ concentrations. Little is known regarding nickel tolerance in the genus Sphingobium. We studied the response of the novel Sphingobium sp. ba1 strain, able to adapt to high Ni2+ concentrations. Differential gene expression in cells cultured in 10 mM Ni2+, investigated by RNA-seq analysis, identified 118 differentially expressed genes. Among the 90 up-regulated genes, a cluster including genes coding for nickel and other metal ion efflux systems (similar to either cnrCBA, nccCBA or cznABC) and for a NreB-like permease was found. Comparative analyses among thirty genomes of Sphingobium species show that this cluster is conserved only in two cases, while in the other genomes it is partially present or even absent. The differential expression of genes encoding proteins which could also work as Ni2+-accumulators (HupE/UreJ-like protein, NreA and components of TonB-associated transport and copper-homeostasis systems) was also detected. The identification of Sphingobium sp. ba1 strain adaptive mechanisms to nickel ions, can foster its possible use for biodegradation of poly-aromatic compounds in metal-rich environments.

RESUMO

A una muestra de 873 trabajadores de organizaciones públicas de Argentina, se ha administrado el Cuestionario de Evaluación de Factores Psicosociales (CEFAP) que incluye once dimensiones, con una serie de ítems con formato tipo Likert organizados de acuerdo con un modelo teórico según el cual éstos cubrirían el espectro de factores psicosociales que contextualizan el trabajo. Todos los factores mostraron una alta consistencia interna, con valores α de Cronbach comprendidos entre .49 (Relación salud-trabajo) y .92 (Apoyo Social y Estima). Además, el cuestionario cuenta con un apartado donde se relevan variables sociolaborales. Los resultados indican que el CEFAP reproduce fielmente la estructura del modelo teórico propuesto ampliando lo presentado por otros instrumentos de evaluación.


The Questionnaire for the Evaluation of Psychosocial Factors (CEFAP) was administered to a sample of 873 employees of public organizations of Argentina. The questionnaire includes eleven dimensions, with a series of items Likert-formatted organized according to a theoretical model that states that these would cover the spectrum of psychosocial factors that contextualize the working activity. All factors showed high internal consistency with Cronbach α values ranging from .49 (Health-work relationship) and .92 (Social Support and Esteem). In addition, the questionnaire has a section where occupational variables are collected. The results indicate that the CEFAP faithfully reproduces the structure of the proposed theoretical model, expanding what was presented by other assessment tools.

RESUMO

We hypothesize that melanocortin receptors (MC) could activate tissue protective circuit in a model of streptozotocin- (STZ-) induced diabetic retinopathy (DR) in mice. At 12-16 weeks after diabetes induction, fluorescein angiography (FAG) revealed an approximate incidence of 80% microvascular changes, typical of DR, in the animals, without signs of vascular leakage. Occludin progressively decreased in the retina of mice developing retinopathy. qPCR of murine retina revealed expression of two MC receptors, Mc1r and Mc5r. The intravitreal injection (5 µL) of the selective MC1 small molecule agonist BMS-470539 (33 µmol) and the MC5 peptidomimetic agonist PG-901 (7.32 nM) elicited significant protection with regular course and caliber of retinal vessels, as quantified at weeks 12 and 16 after diabetes induction. Mouse retina homogenate settings indicated an augmented release of IL-1α, IL-1ß, IL-6, MIP-1α, MIP-2α, MIP-3α, and VEGF from diabetic compared to nondiabetic mice. Application of PG20N or AGRP and MC5 and MC1 antagonist, respectively, augmented the release of cytokines, while the agonists BMS-470539 and PG-901 almost restored normal pattern of these mediators back to nondiabetic values. Similar changes were quantified with respect to Ki-67 staining. Finally, application of MC3-MC4 agonist/antagonists resulted to be inactive with respect to all parameters under assessment.

RESUMO

This study investigated the effects of the new aldose reductase inhibitor benzofuroxane derivative 5(6)-(benzo[d]thiazol-2-ylmethoxy)benzofuroxane (BF-5m) on the prolongation of cardiac QT interval and increase of coronary perfusion pressure (CPP) in isolated, high glucose (33.3 mM D-glucose) perfused rat hearts. BF-5m was dissolved in the Krebs solution at a final concentration of 0.01 µM, 0.05 µM, and 0.1 µM. 33.3 mM D-glucose caused a prolongation of the QT interval and increase of CPP up to values of 190 ± 12 ms and 110 ± 8 mmHg with respect to the values of hearts perfused with standard Krebs solution (11.1 mM D-glucose). The QT prolongation was reduced by 10%, 32%, and 41%, respectively, for the concentration of BF-5m 0.01 µM, 0.05 µM, and 0.1 µM. Similarly, the CPP was reduced by 20% for BF-5m 0.05 µM and by 32% for BF-5m 0.1 µM. BF-5m also increased the expression levels of sirtuin 1, MnSOD, eNOS, and FOXO-1, into the heart. The beneficial actions of BF-5m were partly abolished by the pretreatment of the rats with the inhibitor of the sirtuin 1 activity EX527 (10 mg/kg/day/7 days i.p.) prior to perfusion of the hearts with high glucose + BF-5m (0.1 µM). Therefore, BF-5m supplies cardioprotection from the high glucose induced QT prolongation and increase of CPP.

RESUMO

Rats receiving daily intraperitoneal administration of O2 and running on a treadmill covered an average distance of 482.8 ± 21.8 m/week as calculated during 5-week observation. This distance was increased in rats receiving daily intraperitoneal administration of an oxygen/O3 mixture at a dose of 100; 150; and 300 µg/kg with the maximum increase being +34.5% at 300 µg/kg and still present after stopping the administration of oxygen/O3. Oxygen/O3 decreased the mean arterial blood pressure (-13%), the heart rate (-6%), the gastrocnemius and cardiac hypertrophy, and fibrosis and reduced by 49% the left ventricular mass and relative wall thickness measurements. Systolic and diastolic functions were improved in exercised oxygen/O3 rats compared to O2 rats. Oxygen/O3 treatment led to higher MPI index starting from the dose of 150 µg/kg (p < 0.05) and more effective (+14%) at a dose of 300 µg/kg oxygen/O3. Oxygen/O3 dose-dependently increased the expression of the antioxidant enzymes Mn-SOD and GPx1 and of eNOS compared to the exercised O2 rats. The same doses resulted in decrease of LDH levels, CPK, TnI, and nitrotyrosine concentration in the heart and gastrocnemius tissues, arguing a beneficial effect of the ozone molecule against the fatigue induced by a prolonged high intensity exercise.

RESUMO

The reconstitution of the integral membrane protein photosynthetic reaction center (RC) in polymersomes, i.e. artificial closed vesicles, was achieved by the micelle-to-vesicle transition technique, a very mild protocol based on size exclusion chromatography often used to drive the incorporation of proteins contemporarily to liposome formation. An optimized protocol was used to successfully reconstitute the protein in a fully active state in polymersomes formed by the tri-block copolymers PMOXA22-PDMS61-PMOXA22. The RC is very sensitive to its solubilizing environment and was used to probe the positioning of the protein in the vesicles. According to charge-recombination experiments and to the enzymatic activity assay, the RC is found to accommodate in the PMOXA22 region of the polymersome, facing the water bulk solution, rather than in the PDMS61 transmembrane-like region. Furthermore, polymersomes were found to preserve protein integrity efficiently as the biomimetic lipid bilayers but show a much longer temporal stability than lipid based vesicles.

RESUMO

Rat endotoxin-induced uveitis (EIU) is a well-established model of human uveitis. In this model, intravitreal injection of resolvin D1 (RvD1, 10-100-1000 ng/kg) 1 hour after subcutaneous treatment of Sprague-Dawley rats with lipopolysaccharide (LPS, 200 µg/rat) significantly prevented the development of uveitis into the eye. RvD1 dose-dependently increased the expression of sirtuin-1 (SIRT1) within the eye, while it decreased the expression of acetyl-p53 and acetyl-FOXO1. These effects were accompanied by local downregulation of some microRNAs related to the expression and activity of SIRT1. These were miR-195-5p, miR-200a-3p, miR-34a-5p, and miR-145-5p. An increase of manganese superoxide dismutase and decrease of caspase 3 were evident after RvD1 treatment. In another set of experiments, the protective effects of RvD1 (1000 ng/kg) were partly abolished by the pretreatment of the rats with EX527 (10 mg/kg/day, i.p.), a specific inhibitor of SIRT1 activity, for 7 days prior to the induction of EIU in rats. Similarly, the effects of RvD1 (1000 ng/kg) on the SIRT1 protein expression were abolished by Boc2, N-t-butoxycarbonyl-PLPLP, a specific formyl-peptide receptor type 2/lipoxin A receptor antagonist. Therefore, an interplay of the SIRT1 activity on the RvD1 mediated resolution of EIU is argued.

RESUMO

A un colectivo de 1902 trabajadores de organizaciones públicas y privadas de Argentina, se ha administrado el Cuestionario de Estilos, Modalidades y Tipos de Acoso Laboral (CEMTAL) que incluye una dimensión individual, con una serie de ítems con formato tipo Likert organizados de acuerdo con un modelo teórico según el cual el Acoso está compuesto por 5 factores estructurales (Relacionalidad Intrusividad, Descaliicación, Acatamiento Normativo y Contacto Físico/Sexual) y una escala de Efectos sintomatológicos. Todos los factores mostraron una alta consistencia interna, con valores α de Cronbach comprendidos entre .67 (Contacto Físico/Sexual) y .88 (Intrusividad). Además, el cuestionario cuenta con una dimensión organizacional compuesta por cuatro escalas creadas ad hoc para evaluar ese aspecto. Los resultados indican que el CEMTAL reproduce fielmente la estructura del modelo teórico propuesto. Además, no solo evalúa el Acoso Laboral desde un doble enfoque (objetivo- subjetivo) sino que complementa la perspectiva individual con una organizacional.


The questionnaire of styles, forms and types of Mobbing (CEMTAL) was administered to a group of 1902 workers from public and private organizations in Argentina. The questionnaire includes an individual dimension, with a series of items Likert-type formatted, organized according to a theoretical model in which harassment is composed of 5 structural factors (Relationality, Intrusiveness, Disqualification, Regulatory compliance, and Physical/Sexual contact) and a Scale of symptoms. All factors showed a high internal consistency, with values α of Cronbach between .67 (Physical /Sexual contact) and .88 (Int rusiveness). The questionnaire also includes an organizational dimension made up of four scales created ad hoc to evaluate this aspect. The results indicate that the CEMTAL faithfully reproduces the structure of the proposed theoretical model. In addition, it not only evaluates mobbing from a twin-track approach (objective - subjective) but it complements the individual perspective with an organizational one.

RESUMO

This study investigated the protective effects of intravitreal Resolvin D1 (RvD1) against LPS-induced rat endotoxic uveitis (EIU). RvD1 was administered into the right eye at a single injection of 5 µL volume containing 10-100-1000 ng/kg RvD1 1 h post-LPS injection (200 µg, Salmonella minnesota) into thefootpad of Sprague-Dawley rats. 24 h later, the eye was enucleated and examined for clinical, biochemical, and immunohistochemical evaluations. RvD1 significantly and dose-dependently decreased the clinical score attributed to EIU, starting from the dose of 10 ng/kg and further decreased by 100 and 1000 ng/kg. These effects were accompanied by changes in four important determinants of the immune-inflammatory response within the eye: (i) the B and T lymphocytes, (ii) the miRNAs pattern, (iii) the ubiquitin-proteasome system (UPS), and (iv) the M1/M2 macrophage phenotype. LPS+RvD1 treated rats showed reduced presence of B and T lymphocytes and upregulation of miR-200c-3p, miR 203a-3p, miR 29b-3p, and miR 21-5p into the eye compared to the LPS alone. This was paralleled by decreases of the ubiquitin, 20S and 26S proteasome subunits, reduced presence of macrophage M1, and increased presence of macrophage M2 in the ocular tissues. Accordingly, the levels of the cytokine TNF-α, the chemokines MIP1-α and NF-κB were reduced.

RESUMO

A five-year-old intact male golden retriever dog was evaluated for cervical pain and right hemiparesis. Clinical and computed tomography features suggested a caudal cervical instability and myelopathy due to a cervicoscapular malformation resembling the human Klippel-Feil Syndrome with Sprengel Deformity, a rare complex congenital disorder. Polymerase chain reaction (PCR) and direct sequencing of MEOX1, PAX1 and FGFR3 genes were performed in this dog to investigate a possible underlying genetic predisposition, but no mutations were detected in the coding regions of the three target genes evaluated. Other genes can be involved in this condition in dogs and require further investigation. This report describes a cervical vertebral fusion and complex scapular anomaly in a dog. The presence of an omovertebral bone should be considered in the setting of signs characteristic of myelopathy in dogs with or without obvious skeletal deformity.

RESUMO

The study investigated the effects of the aldose reductase (AR) inhibitor benzofuroxane derivative 5(6)-(benzo[d]thiazol-2-ylmethoxy) benzofuroxane (herein referred to as BF-5m) on the biochemical and tissue alterations induced by endotoxic uveitis in rats. BF-5m has been administered directly into the vitreous, in order to assess the expression and levels of (i) inflammatory markers such as the ocular ubiquitin-proteasome system, NF-κB, TNF-α, and MCP-1; (ii) prooxidant and antioxidant markers such as nitrotyrosine, manganese superoxide dismutase (MnSOD), and glutathione peroxidase (GPX); (iii) apoptotic/antiapoptotic factors caspases and Bcl-xl; (iv) markers of endothelial progenitor cells (EPCs) recruitment such as CD34 and CD117. 5 µL of BF-5m (0.01; 0.05; and 0.1 µM) into the right eye decreased in a dose-dependent manner the LPS-induced inflammation of the eye, reporting a clinical score 1. It reduced the ocular levels of ubiquitin, 20S and 26S proteasome subunits, NF-κB subunits, TNF-α, MCP-1, and nitrotyrosine. BF-5m ameliorated LPS-induced decrease in levels of MnSOD and GPX. Antiapoptotic effects were seen from BF-5m by monitoring the expression of Bcl-xl, an antiapoptotic protein. Similarly, BF-5m increased recruitment of the EPCs within the eye, as evidenced by CD34 and CD117 antibodies.

El diagnóstico de acoso laboral resulta un espacio apto para la discusión sobre alternativas metodológicas, factores implicados, la posición de los que se consideran víctimas del mismo y las modalidades organizacionales. Esta discusión ha girado habitualmente en torno a la pertinencia de la perspectiva subjetiva u objetiva para brindar tasas representativas y confiables, aunque también incluye la cautela que los investigadores debieran desplegar frente a distintas formas de expectativas que las organizaciones tienen acerca de lo que desean encontrar.Profundizando este debate, se expone la forma en que ambos criterios funcionan a la hora de producir las tasas de incidencia y el proceso diagnóstico. Además, se comparan los aspectos en los que se produce solapamiento o diferencias entre ambos criterios, y el análisis de las continuidades y discontinuidades con los resultados de otras investigaciones. Por último, se explora el criterio objetivo en términos de las combinaciones de factores y su relación con las tasas de víctimas, según las variables socio-organizacionales y sociodemográficas relevantes...

RESUMO

BACKGROUND AND AIMS: In Italy, the reimbursed use of incretin mimetics and incretin enhancers was subject to enrollment of patients into a web-based system recording the general demographic and clinical data of patients. We report the utilization data of glucagon-like peptide 1 (GLP1) receptor agonists and dipeptidylpeptidase-4 (DPP4) inhibitors in clinical practice as recorded by the Italian Medicines Agency (AIFA) Monitoring Registry. METHODS AND RESULTS: From February 2008 to August 2010, 75,283 patients with type 2 diabetes were entered into the registry and treated with exenatide, sitagliptin, or vildagliptin. The treatment was administered to patients in a wide range of ages (≥75 years, n = 6125 cases), body mass index (BMI) (≥35 kg/m(2), n = 22,015), and metabolic control (HbA(1c) ≥ 11% ((96 mmol/mol), n = 3151). Overall, 1116 suspected adverse drug reactions were registered, including 12 cases of acute pancreatitis (six on exenatide). Hypoglycemic episodes mainly occurred in combination with sulfonylureas. Treatment discontinuation for the three drugs (logistic regression analysis) was negatively associated with the male gender and positively with baseline HbA1c, diabetes duration, and, limitedly to DPP-4 inhibitors, with BMI. Treatment discontinuation (including loss to follow-up, accounting for 21-26%) was frequent. Discontinuation for treatment failure occurred in 7.7% of cases (exenatide), 3.8% (sitagliptin), and 4.1% (vildagliptin), respectively, corresponding to 27-40% of all discontinuations, after excluding lost to follow-up. HbA1c decreased on average by 0.9-1.0% (9 mmol/mol). Body weight decreased by 3.5% with exenatide and by 1.0-1.5% with DPP-4 inhibitors. CONCLUSIONS: In the real world of Italian diabetes centers, prescriptions of incretins have been made in many cases outside the regulatory limits. Nevertheless, when appropriately utilized, incretins may grant results at least in line with pivotal trials.

RESUMO

This case report presents a Belgian Shepherd Malinois dog affected by hemophilia A recognized at the age of seven months. The clinical follow-up including all the diagnostic procedures leading to the final diagnosis and the course of this disorder are presented. This is a typical proband case demonstrating the appearance of this genetic disease in a breed never involved by this coagulation disorder so far documented that started an intensive and laborious plan to reduce the incidence of hemophilia A and the further appearance of new cases.

RESUMO

An increased R2 recovery component of the blink reflex (R2-BRrc) has been observed in Parkinson's disease (PD), cranio-cervical dystonia, dystonic tremor and essential tremor with associated resting tremor (rET), while the BRrc was reported normal in patients with essential tremor (ET). Distinguishing rET from tremor dominant PD (tPD) may be challenging especially in the first stages of the diseases, in the absence of DAT-SPECT investigation. We evaluated the possible usefulness of BRrc for differentiating subjects with de novo tPD from those with rET. We investigated R2-BRrc at interstimulus intervals (ISI) of 100, 150, 200, 300, 400, 500 and 750 ms in 11 participants with tPD, 10 with rET and 20 healthy controls. All participants underwent DAT-SPECT and cardiac MIBG scintigraphy. R2 recovery was significantly enhanced in tPD compared to controls at all investigated ISIs (p < 0.001), while in subjects with rET patients BRrc was significantly increased compared to controls at ISI 150, 200, 300, 400, 500 and 750 ms (p < 0.001). At ISI 100 R2-BRrc distinguished patients participants with de novo tPD from those with rET with a sensitivity, specificity and accuracy of 100%. Our findings demonstrate the usefulness of BRrc for differentiating de novo tPD from rET.
