Rubella susceptibility in pregnant women and results of a postpartum immunization strategy in Catalonia, Spain

BACKGROUND: Elimination of congenital rubella syndrome depends not only on effective childhood immunization but also on the identification and immunization of rubella susceptible women. We assessed rubella susceptibility among pregnant women and evaluated the adherence and response to postpartum immunization with measles, mumps and rubella (MMR) vaccine. METHODS: Cross-sectional study of women who gave birth at the Hospital Clinic de Barcelona (Spain) between January 2008 and December 2013. Antenatal serological screening for rubella was performed in all women during pregnancy. In rubella-susceptible women, two doses of MMR vaccine were recommended following birth. We evaluated rubella serological response to MMR vaccination in mothers who complied with the recommendations. RESULTS: A total of 22,681 pregnant women were included in the study. The mean age was 32.3 years (SD 5.6), and 73.6% were primipara. The proportion of immigrants ranged from 43.4% in 2010 to 38.5% in 2012. The proportion of women susceptible to rubella was 5.9% (1328). Susceptibility to rubella declined with increasing maternal age. Immigrant pregnant women were more susceptible to rubella (7.6%) than women born in Spain (4.6%). Multivariate analyses showed that younger age (</=19 years) aOR 1.7 (95% CI 1.1-2.5), primiparas aOR 1.3 (95% CI 1.1-1.5) and immigrant women aOR 1.6 (95% CI 1.4-1.8) were more likely to be susceptible. The second dose of MMR vaccine was received by 57.2% (718/1256) of rubella-susceptible women, with the highest proportion being immigrant women compared with women born in Spain. After vaccination, all women showed rubella immunity. CONCLUSIONS: The higher rubella susceptibility found in the three youngest age groups and in immigrant women highlights the relevance of antenatal screening, in order to ensure identification and postpartum immunization. The postpartum immunization strategy is an opportunity to protect women of childbearing age and consequently prevent occurrence of CRS, and to increase vaccination coverage against rubella and other vaccine-preventable diseases

This study aimed to establish sensitization patterns to five peach components across Europe and in Japan, to explore their relation to pollen and foods and to predict symptom severity. METHODS: In twelve European (EuroPrevall project) and one Japanese outpatient clinic, a standardized clinical evaluation was conducted in 1231 patients who reported symptoms to peach and/or were sensitized to peach. Specific IgE against Pru p 1, 2, 3, 4 and 7 and against Cup s 7 was measured in 474 of them. Univariable and multivariable Lasso regression was applied to identify combinations of parameters predicting severity. RESULTS: Sensitization to Pru p 3 dominated in Southern Europe but was also quite common in Northern and Central Europe. Sensitization to Pru p 7 was low and variable in the European centers but very dominant in Japan. Severity could be predicted by a model combining age of onset of peach allergy, probable mugwort, Parietaria pollen and latex allergy, and sensitization to Japanese cedar pollen, Pru p 4 and Pru p 7 which resulted in an AUC of 0.73 (95% CI 0.73-0.74). Pru p 3 tended to be a risk factor in South Europe only. CONCLUSIONS: Pru p 7 was confirmed as a significant risk factor for severe peach allergy in Europe and Japan. Combining outcomes from clinical and demographic background with serology resulted in a model that could better predict severity than CRD alone.Peer reviewe

Host cell targets for African swine fever virus

Viruses are strict intracellular pathogens that require the cellular environment to complete a successful infection. Among them, African swine fever virus (ASFV) is an evolutionary ancient DNA virus, endemic in Africa, which is nowadays causing an emergent disease in Europe with a potential high economic impact in the pig industry. It is well known that host-cell components are critical crossroads mapping the virus path for a productive infection, some of them at the endocytic pathway. Considering that ASFV infectious cycle strongly relies in several factors from the host cell, the study of virus-host interactions remains crucial as they will reveal the obstacles, routes and tracks, hints and the target waypoint in the virus journey to destination. © 2015 Elsevier B.V

Comparative inhibitory activity of the stilbenes resveratrol and oxyresveratrol on African swine fever virus replication

Stilbenols are polyphenolic phytoalexins produced by plants in response to biotic or abiotic stress. These compounds have received much attention because of their significant biological effects. One of these is their antiviral action, which has previously been documented for two members of this class, namely resveratrol and oxyresveratrol. Here we tested the antiviral effect of these two compounds on African swine fever virus, the only member of the newly created family Asfarviridae and a serious limitation to porcine production worldwide. Our results show a potent, dose-dependent antiviral effect of resveratrol and oxyresveratrol in vitro. Interestingly, this antiviral activity was found for these synthetic compounds and also for oxyresveratrol extracted from new natural sources (mulberry twigs). The antiviral effect of these two drugs was demonstrated at concentrations that do not induce cytotoxicity in cultured cells. Moreover, these antivirals achieved a 98-100% reduction in viral titers. Both compounds allowed early protein synthesis but inhibited viral DNA replication, late viral protein synthesis and viral factory formation. © 2011 Elsevier B.V

Uso de Psicofármacos en prisión (CP Madrid III) The use of psychotropic drugs in prison (CP Madrid III)

El uso de psicofármacos en el entorno de atención primaria está aumentando exponencialmente y el medio penitenciario no constituye una excepción a esta tendencia. Con alguna frecuencia estos tratamientos se prescriben buscando utilidades terapéuticas en relación con trastornos de personalidad, dependencias y conductas disfuncionales que no han sido aceptadas como indicaciones (uso compasivo). El presente estudio ha permitido una descripción pormenorizada del uso de psicofármacos en el Centro Penitenciario (CP) Madrid III, uno de los centros con menor gasto farmacéutico de la Comunidad Autónoma. Durante dos semanas se registraron todas las prescripciones de psicofármacos junto con diversos parámetros que pudiesen resultar condicionantes. Un 23,46% de la población recibía algún tipo de psicofármaco; el 76% de los internos a tratamiento recibía uno o dos psicofármacos, un 65% tenía prescritos ansiolíticos, un 38% antidepresivos y un 27% antipsicóticos. El consumo total de psicofármacos ascendió a 9.840 Dosis Diarias de Mantenimiento, un 46% de las cuales correspondían con ansiolíticos, un 17% con antidepresivos y un 14% con antipsicóticos. En dos semanas, el gasto total sumó 5.379 euros y los antipsicóticos acumularon un 72% del coste (3.857 euros). Hay indicios de que el uso compasivo de nuevos antipsicóticos y antiepilépticos supone un porcentaje sustancial del incremento del gasto con dudosa utilidad. Los resultados del estudio apuntan al médico prescriptor como agente primordial en relación con qué, cuánto y con qué coste se prescribe. Al contrario de lo que cabía esperar, no se encontró asociación entre variables como la edad, nacionalidad, grado o tipo de condena de los internos y la prescripción de los distintos subgrupos de psicofármacos con la excepción de las benzodiacepinas.<br>The use of psychotropic drugs in primary care has exponentially increased and prisons are no exception. These drugs are often prescribed in order to find therapeutic uses in the fields of personality disorders, addictions, and dysfunctional behaviours that have not been accepted as indications (compassive use). This study enabled us to make a detailed description of the use of psychiatric drugs at the Madrid III prison, a centre with one of the lowest levels of pharmaceutical expenditure in the region. For a two-week period, all prescriptions of psychotropic drugs were collected and registered along with data of several possible conditioning factors. 20.5% of the population was receiving some kind of psychiatric drug; 76% of those inmates undergoing treatment were receiving one or two psychotropic drugs; 65% were taking sedatives, 38% antidepressants and 27% antipsychotic medication. The total amount of psychotropics consumed was 9,840 DDDs, 46% of which were sedatives, 17% of those being antidepressants and the other 14% antipsychotics. The total cost of the fortnight&rsquo;s treatment was 5,379 euros, 72% of which was spent on antipsychotic medication. There are signs that compassive use of the latest generation of antipsychotics and antiepileptics, and the newer antidepressants are a main cause of the dramatic increase in cost, and cost efficiency has not always been clearly demonstrated. One of the key influencing factors on amount, type and cost of treatment was the prescriptor. An unexpected result was that of finding no relationship between age, nationality, grade or other individual variables and prescription of different kind of medication, with the exception of benzodiazepines

African swine fever virus infects macrophages, the natural host cells, via clathrin- and cholesterol-dependent endocytosis

The main cellular target for African swine fever virus (ASFV) is the porcine macrophage. However, existing data about the early phases of infection were previously characterized in non-leukocyte cells such as Vero cells. Here, we report that ASFV enters the natural host cell using dynamin-dependent and clathrin-mediated endocytosis. This pathway is strongly pH-dependent during the first steps of infection in porcine macrophages. We investigated the effect of drugs inhibiting several endocytic pathways in macrophages and compared ASFV with vaccinia virus (VV), which apparently involves different entry pathways. The presence of cholesterol in cellular membranes was found to be essential for a productive ASFV infection while actin-dependent endocytosis and the participation of phosphoinositide-3-kinase (PI3K) activity were other cellular factors required in the process of viral entry. These findings improved our understanding of the ASFV interactions with macrophages that allow for successful viral replication. © 2015 Elsevier B.V

Antiviral role of IFITM proteins in African swine fever virus infection

The interferon-induced transmembrane (IFITM) protein family is a group of antiviral restriction factors that impair flexibility and inhibit membrane fusion at the plasma or the endosomal membrane, restricting viral progression at entry. While IFITMs are widely known to inhibit several single-stranded RNA viruses, there are limited reports available regarding their effect in double-stranded DNA viruses. In this work, we have analyzed a possible antiviral function of IFITMs against a double stranded DNA virus, the African swine fever virus (ASFV). Infection with cell-adapted ASFV isolate Ba71V is IFN sensitive and it induces IFITMs expression. Interestingly, high levels of IFITMs caused a collapse of the endosomal pathway to the perinuclear area. Given that ASFV entry is strongly dependent on endocytosis, we investigated whether IFITM expression could impair viral infection. Expression of IFITM1, 2 and 3 reduced virus infectivity in Vero cells, with IFITM2 and IFITM3 having an impact on viral entry/uncoating. The role of IFITM2 in the inhibition of ASFV in Vero cells could be related to impaired endocytosis-mediated viral entry and alterations in the cholesterol efflux, suggesting that IFITM2 is acting at the late endosome, preventing the decapsidation stage of ASFV.

Gynaecological malignancies at a tertiary care centre in Mozambique

Objective: To determine the frequency of gynaecological cancers over an 18-year-period in Mozambique a country located in South Eastern sub-Saharan Africa, an area in which comprehensive statistics on cancer are limited. Materials and Methods: Retrospective review of the pathological records of gynaecological cancers at the Maputo Central Hospital from January 1991 to December 2008. Results: 3,726 gynaecological cancers were reported. Malignant neoplasms of the uterine cervix (64.0% of all tumours) were the most frequent cancers, followed by breast (23.2%), vulvar-vaginal (4.1%), ovarian cancers (3.8%), cancers of the uterine corpus (3.3%), and gestational choriocarcinoma (1.7%). Tumours of the uterine cervix, vulva/vagina, uterine corpus, and ovary increased in number three times, whereas breast cancers increased five times during the study period. Conclusions: Malignant tumours related to human papillomavirus (HPV) accounted for over two-thirds of all malignancies. Screening for cervical cancer and vaccination against HPV should be a health priority in sub-Saharan Africa
