RESUMO

BACKGROUND: Sensitive skin is a common condition of hyper-reactivity to external stimuli, e.g. heat or abrasion. The symptoms are subjective but can be measured using validated emotional and technical methods. Avène water has several beneficial effects on the skin. In vitro studies indicated that the active component of this natural spring water, Aquaphilus dolomiae extract-G3 (ADE-G3), modulates cutaneous sensitivity via an anaesthetic-like mechanism. OBJECTIVES: To assess facial skin reactivity after repeated application of two formulations containing ADE-G3. METHODS: In open-label studies, healthy subjects with sensitive facial skin applied cream or balm twice daily for 84 days. The severity of skin sensitivity was measured using the Sensitive Scale (based on quantifying visible or subjective signs). Subjective responses associated with pain or uncomfortable feeling were assessed by measuring electrodermal response (EDR). This involves measuring variations in skin electrical resistance due to non-conscious physiological changes in activity of the sympathetic nervous system. Subjects were also evaluated for beneficial effects according to a quantitative approach using semantic assessment of a question regarding their skin quality. Evaluations were performed before and after the first application, and after 29/30, 56 and 84 days of twice daily use. RESULTS: There was a significant decrease in the EDR after stimuli immediately after the application of both ADE-G3 formulations, which continued to decrease over 84 days (40-50% decrease by D85). Likewise, all physical and functional signs of the Sensitive Scale were significantly decreased immediately after the first application and at all time points tested after treatment. Verbatim analysis revealed a semantic shift, from mainly negative terms on D1 to mainly positive terms at D85 for both tested products. CONCLUSIONS: These results demonstrated that two formulations containing ADE-G3 reduced skin sensitivity, indicating a decreased activation of the sympathetic nervous system associated with this condition.

RESUMO

OBJECTIVE: To assess the benefits and safety of early human fibrinogen concentrate in postpartum haemorrhage (PPH) management. DESIGN: Multicentre, double-blind, randomised placebo-controlled trial. SETTING: 30 French hospitals. POPULATION: Patients with persistent PPH after vaginal delivery requiring a switch from oxytocin to prostaglandins. METHODS: Within 30 minutes after introduction of prostaglandins, patients received either 3 g fibrinogen concentrate or placebo. MAIN OUTCOME MEASURES: Failure as composite primary efficacy endpoint: at least 4 g/dl of haemoglobin decrease and/or transfusion of at least two units of packed red blood cells within 48 hours following investigational medicinal product administration. Secondary endpoints: PPH evolution, need for haemostatic procedures and maternal morbidity-mortality within 6 ± 2 weeks after delivery. RESULTS: 437 patients were included: 224 received FC and 213 placebo. At inclusion, blood loss (877 ± 346 ml) and plasma fibrinogen (4.1 ± 0.9 g/l) were similar in both groups (mean ± SD). Failure rates were 40.0% and 42.4% in the fibrinogen and placebo groups, respectively (odds ratio [OR] = 0.99) after adjustment for centre and baseline plasma fibrinogen; (95% CI 0.66-1.47; P = 0.96). No significant differences in secondary efficacy outcomes were observed. The mean plasma FG was unchanged in the Fibrinogen group and decreased by 0.56 g/l in the placebo group. No thromboembolic or other relevant adverse effects were reported in the Fibrinogen group versus two in the placebo group. CONCLUSIONS: As previous placebo-controlled studies findings, early and systematic administration of 3 g fibrinogen concentrate did not reduce blood loss, transfusion needs or postpartum anaemia, but did prevent plasma fibrinogen decrease without any subsequent thromboembolic events. TWEETABLE ABSTRACT: Early systematic blind 3 g fibrinogen infusion in PPH did not reduce anaemia or transfusion rate, reduced hypofibrinogenaemia and was safe.

RESUMO

One Health Surveillance (OHS) implements the One Health approach to improving health by collecting data and producing information to support integrated action across the animal health, human health and environment sectors. The purpose of this study was to survey the biosurveillance community to assess its OHS practices and capabilities, its attitudes towards OHS (perceived value), and the factors that motivate its members to implement OHS practices. The authors used a convenience sample of 185 professionals from multiple domains and 44 nations. They examined the extent to which these professionals implemented OHS, gathered their opinions on the value of OHS, assessed their perceptions of the capacity to perform specific OHS tasks and identified their priorities for change. Over 85% of all respondents said that they considered OHS to be beneficial, with no significant differences between work domains or country income groups; over 50% indicated that they already applied OHS. Obtaining access to data collected by other domains was both the most frequent challenge and the most difficult to improve. The highest priority for improvement was having the ability to send and receive electronic data. Respondents from low-income or middle-income countries were more motivated to make improvements than stakeholders from high-income countries. These findings provide a snapshot of current opinions and practices and, together with suggestions for improvements from professionals in the field, can help to target priority needs for OHS information, training and resources.


La surveillance Une seule santé opérationnalise la méthode Une seule santé pour une meilleure santé à travers la collecte de données et la production d'informations visant à soutenir la mobilisation transversale des secteurs de la santé animale, de la santé publique et de la santé environnementale en vue d'une action intégrée. Les auteurs présentent les résultats d'une enquête menée auprès des professionnels en charge de la biosurveillance afin d'évaluer leurs pratiques et capacités en matière de surveillance Une seule santé, leurs attitudes à l'égard de cette surveillance (c'est-à-dire leur perception de l'intérêt de la démarche) et les facteurs susceptibles de les motiver à la mettre en oeuvre. Les auteurs ont procédé à un échantillonnage de commodité de 185 intervenants issus de plusieurs secteurs dans 44 pays. Ils ont ensuite analysé le niveau de mise en oeuvre de la surveillance Une seule santé chez ces intervenants, recueilli leurs opinions concernant l'intérêt de la démarche, évalué la perception qu'ils avaient de leur capacité à mener à bien certaine tâches spécifiques dans ce domaine et identifié leurs priorités en vue du changement. Plus de 85 % des répondants ont déclaré considérer la surveillance Une seule santé comme étant bénéfique, résultat ne présentant pas de corrélation significative avec le secteur professionnel des personnes interrogées ni avec le niveau de revenu de leur pays ; plus de 50 % des répondants ont par ailleurs indiqué qu'ils appliquaient déjà les principes d'une surveillance Une seule santé. La difficulté la plus fréquente et qui paraissait la plus difficile à résoudre était celle de pouvoir accéder aux données enregistrées par d'autres secteurs. La première des priorités identifiées en vue d'une amélioration concernait la capacité d'envoyer et de recevoir des données électroniques. La motivation à introduire des améliorations était plus forte chez les répondants des pays à revenu faible ou intermédiaire que chez les parties prenantes des pays à revenus élevés. Ces résultats, qui offrent un instantané des opinions et des pratiques actuelles assorti de propositions concrètes d'amélioration formulées par les professionnels de terrain devraient pouvoir contribuer à cibler les besoins prioritaires en matière d'information, de formation et de ressources dédiées à la surveillance Une seule santé.


Practicar la vigilancia en clave de Una sola salud significa traducir esta idea en la práctica con el fin de mejorar la salud reuniendo datos y generando información a partir de la cual actuar de forma integrada en los sectores de la sanidad animal, la salud humana y el medio ambiente. Los autores describen un estudio de los círculos dedicados a la vigilancia biológica que tenía por objetivo evaluar sus procedimientos y capacidades de vigilancia en clave de Una sola salud, sus actitudes al respecto (valor atribuido) y los factores que los motivan a instaurar procedimientos concebidos desde la lógica de Una sola salud. Para ello los autores utilizaron una muestra de conveniencia de 185 profesionales de múltiples disciplinas y 44 países. Tras determinar en qué medida esos profesionales practicaban la vigilancia en clave de Una sola salud, les pidieron su opinión sobre la utilidad de este tipo de vigilancia, evaluaron la capacidad que subjetivamente se atribuían de efectuar labores específicas de vigilancia en clave de Una sola salud y determinaron aquellos cambios que esas personas juzgaban prioritarios. Más de un 85% de los encuestados dijo considerar beneficiosa la vigilancia en clave de Una sola salud, sin que se observaran diferencias significativas por ámbito de trabajo o por países según el grupo de ingresos. Más de un 50% afirmó que ya aplicaba este tipo de vigilancia. El problema señalado con más frecuencia y juzgado a la vez más difícil de resolver era el del acceso a datos obtenidos desde otros ámbitos de trabajo. El aspecto que más urgía mejorar era el de la capacidad de enviar y recibir datos electrónicos. Los encuestados de países de nivel bajo o medio de ingresos mostraban mayor motivación a la hora de introducir mejoras que sus homólogos de países de ingresos altos. Estas conclusiones, que ofrecen una «instantánea¼ de las opiniones y prácticas imperantes, pueden ayudar, junto con las propuestas de mejora procedentes de esos profesionales que trabajan sobre el terreno, a seleccionar las necesidades prioritarias de información, formación y recursos para la práctica de la vigilancia en clave de Una sola salud.

RESUMO

West Nile virus (WNV) is a growing public health concern in Europe and there is a need to develop more efficient early detection systems. Nervous signs in horses are considered to be an early indicator of WNV and, using them in a syndromic surveillance system, might be relevant. In our study, we assessed whether or not data collected by the passive French surveillance system for the surveillance of equine diseases can be used routinely for the detection of WNV. We tested several pre-processing methods and detection algorithms based on regression. We evaluated system performances using simulated and authentic data and compared them to those of the surveillance system currently in place. Our results show that the current detection algorithm provided similar performances to those tested using simulated and real data. However, regression models can be easily and better adapted to surveillance objectives. The detection performances obtained were compatible with the early detection of WNV outbreaks in France (i.e. sensitivity 98%, specificity >94%, timeliness 2·5 weeks and around four false alarms per year) but further work is needed to determine the most suitable alarm threshold for WNV surveillance in France using cost-efficiency analysis.

RESUMO

INTRODUCTION: Pulmonary aspiration of gastric contents in pregnant women undergoing general anesthesia or sedation/analgesia in the peripartum period is a feared complication in obstetric anesthesia. We assessed the changes in antral cross-sectional area (CSA) with ultrasonography in laboring women and in the immediate postpartum period. PATIENTS AND METHODS: In an observational study in a university-affiliated maternity, gastric ultrasonography examinations were performed in non-consecutive laboring women, after epidural analgesia insertion and after childbirth. Assessment of antral CSA, difficulty of performance on a numerical scale, and factors that could influence gastric content were noted. A cut-off value of 381 mm2 was taken for the diagnosis of empty stomach. RESULTS: One hundred women were enrolled in the study. Median antral CSA was 469 mm2 [25th-75th] [324-591] after epidural insertion and 427 mm2 [316-574] after delivery. Antral CSA was ≥ 381 mm2 in 59 of 90 women (65%) after epidural insertion vs. 48 of 100 women (48%) after delivery (P = 0.59). Median variation of antral CSA between two measurements was 36 mm2 [-42 to 114]. Gastric ultrasonography was significantly more difficult to perform during labor than immediately post-delivery (median difficulty score 5 [2-7] vs. 2 [1-4], P < 0.0001). No risk factors (pain, anxiety, diabetes, smoking) were significantly associated with the occurrence of full stomach post-delivery. CONCLUSION: This study demonstrated that 48% of parturients in the immediate postpartum period presented an antral CSA ≥ 381 mm2 , cut-off being accepted for diagnosis of empty stomach and emphasizes the need for re-assessing before any general anesthetic procedure.

RESUMO

OBJECTIVE: This study aimed at increasing the concentration of a hydrophobic lightening agent, Omegalight® , in a hydrophilic cosmetic product by means of encapsulation in lipid-based submicron capsules. The core of these capsules is entirely made of the commercial lightening agent. METHODS: Lipid-based encapsulation systems (LNC) were prepared by the PIT method. Their physicochemical properties were followed over 6 months by dynamic light scattering and zeta potential measurements, and in parallel, the potential degradation of the active ingredient was monitored by HPLC. The stability of the capsules in a cosmetic gel was studied by spectrofluorimetry and rheology measurements. Sensory analysis was used to determine the influence of the presence of capsules in the gel on the consumer's experience. RESULTS: LNC encapsulating Omegalight® were prepared on a laboratory scale and then on a semi-pilot scale. Their hydrodynamic diameters are around 230 nm. The concentration of Omegalight® in the capsules reaches about 84% w/w, which corresponds to 42% of active ingredient. LNC can be dispersed without degradation at concentrations of up to 20% w/w in a hydrogel without modification of the physicochemical or sensory properties of the gel. CONCLUSION: Lipid-based capsules (LNC), an encapsulation system useful for the epidermal delivery of hydrophobic compounds, were adapted to the encapsulation of a commercial lightening agent. The encapsulation permits the dispersion in a stable manner of a very high concentration of a hydrophobic active molecule in a hydrogel while maintaining the physicochemical and sensory properties of the gel.

RESUMO

Clinical observations made by practitioners and reported using web- and mobile-based technologies may benefit disease surveillance by improving the timeliness of outbreak detection. Equinella is a voluntary electronic reporting and information system established for the early detection of infectious equine diseases in Switzerland. Sentinel veterinary practitioners have been able to report cases of non-notifiable diseases and clinical symptoms to an internet-based platform since November 2013. Telephone interviews were carried out during the first year to understand the motivating and constraining factors affecting voluntary reporting and the use of mobile devices in a sentinel network. We found that non-monetary incentives attract sentinel practitioners; however, insufficient understanding of the reporting system and of its relevance, as well as concerns over the electronic dissemination of health data were identified as potential challenges to sustainable reporting. Many practitioners are not yet aware of the advantages of mobile-based surveillance and may require some time to become accustomed to novel reporting methods. Finally, our study highlights the need for continued information feedback loops within voluntary sentinel networks.

RESUMO

The cutaneous penetration of hydrophobic active molecules is of foremost concern in the dermatology and cosmetic formulation fields. The poor solubility in water of those molecules limits their use in hydrophilic forms such as gels, which are favored by patients with chronic skin disease. The aim of this work is to design a novel nanocarrier of hydrophobic active molecules and to determine its potential as an ingredient of a topical form. The nanocarrier consists of an oily core surrounded by a protective shell of alginate, a natural polysaccharide isolated from brown algae. These calcium alginate-based nanocarriers (CaANCs) were prepared at room temperature and without the use of organic solvent by an accelerated nanoemulsification-polymer crosslinking method. The size (hydrodynamic diameter ~200 nm) and surface charge (zeta potential ~ - 30 mV) of the CaANCs are both compatible with their application on skin. CaANCs loaded with a fluorescent label were stable in model hydrophilic galenic forms under different storage conditions. Curcumin was encapsulated in CaANCs with an efficiency of ~95%, fully retaining its antioxidant activity. The application of the curcumin-loaded CaANCs on excised human skin led to a significant accumulation of the active molecules in the upper layers of the skin, asserting the potential of these nanocarriers in active pharmaceutical and cosmetic ingredients topical delivery.

RESUMO

Syndromic surveillance (SyS) systems currently exploit various sources of health-related data, most of which are collected for purposes other than surveillance (e.g. economic). Several European SyS systems use data collected during meat inspection for syndromic surveillance of animal health, as some diseases may be more easily detected post-mortem than at their point of origin or during the ante-mortem inspection upon arrival at the slaughterhouse. In this paper we use simulation to evaluate the performance of a quasi-Poisson regression (also known as an improved Farrington) algorithm for the detection of disease outbreaks during post-mortem inspection of slaughtered animals. When parameterizing the algorithm based on the retrospective analyses of 6 years of historic data, the probability of detection was satisfactory for large (range 83-445 cases) outbreaks but poor for small (range 20-177 cases) outbreaks. Varying the amount of historical data used to fit the algorithm can help increasing the probability of detection for small outbreaks. However, while the use of a 0·975 quantile generated a low false-positive rate, in most cases, more than 50% of outbreak cases had already occurred at the time of detection. High variance observed in the whole carcass condemnations time-series, and lack of flexibility in terms of the temporal distribution of simulated outbreaks resulting from low reporting frequency (monthly), constitute major challenges for early detection of outbreaks in the livestock population based on meat inspection data. Reporting frequency should be increased in the future to improve timeliness of the SyS system while increased sensitivity may be achieved by integrating meat inspection data into a multivariate system simultaneously evaluating multiple sources of data on livestock health.

RESUMO

•Increases in human-wildlife conflicts alongside cultural shifts against lethal control methods are driving the need for alternative wildlife management tools such as fertility control. Contraceptive formulations suitable for oral delivery would permit broader remote application in wildlife species.•This study evaluated the contraceptive effect and immune response to two novel injectable immunocontraceptive formulations targeting the Gonadotropin Releasing Hormone (GnRH): MAF-IMX294 and MAF-IMX294P conjugates, both identified as having potential as oral contraceptives. The study also explored whether in multiparous species immunocontraceptives may either totally prevent reproduction or also affect litter size.•Female rats, chosen as a model species, were given three doses of either MAF-IMX294 or MAF-IMX294P to compare anti-GnRH immune response and reproductive output up to 310 days post-treatment.•Both formulations induced anti-GnRH antibody titres in 100% of rats and significantly impaired fertility compared to control animals. Following treatment with MAF-IMX294 and MAF-IMX294P 0 of 9 and 1 of 10 females respectively produced litters following the first mating challenge 45 days post-treatment, compared to 9 of 9 control animals.•Across the whole 310 day study period 7 of 9 females from the MAF-IMX294 group and 10 of 10 females in the MAF-IMX294P group became fertile, producing at least one litter throughout six mating challenges.•No significant differences were found between the two formulations in antibody titre response or duration of contraceptive effect, with an average time to first pregnancy of 166 days for MAF-IMX294 and 177 days for MAF-IMX294P for all females that became fertile.•Following treatment with MAF-IMX294 and MAF-IMX294P the first litter produced post-infertility in treated females was significantly smaller than in control animals. This indicates treatment with immunocontraceptives may induce an overall suppression of fecundity extending past an initial infertility effect. This increases the potential long-term impact of these immunocontraceptives in multiparous species such as commensal rodents.

RESUMO

OBJECTIVE: To provide national guidelines for the management of women with severe preeclampsia. DESIGN: A consensus committee of 26 experts was formed. A formal conflict of interest (COI) policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The last SFAR and CNGOF guidelines on the management of women with severe preeclampsia was published in 2009. The literature is now sufficient for an update. The aim of this expert panel guidelines is to evaluate the impact of different aspects of the management of women with severe preeclampsia on maternal and neonatal morbidities separately. The experts studied questions within 7 domains. Each question was formulated according to the PICO (Patients Intervention Comparison Outcome) model and the evidence profiles were produced. An extensive literature review and recommendations were carried out and analyzed according to the GRADE® methodology. RESULTS: The SFAR/CNGOF experts panel provided 25 recommendations: 8 have a high level of evidence (GRADE 1±), 9 have a moderate level of evidence (GRADE 2±), and for 7 recommendations, the GRADE method could not be applied, resulting in expert opinions. No recommendation was provided for 3 questions. After one scoring round, strong agreement was reached between the experts for all the recommendations. CONCLUSIONS: There was strong agreement among experts who made 25 recommendations to improve practices for the management of women with severe preeclampsia.

RESUMO

Three studies were performed to investigate the mechanism of action and evaluate the efficacy of a topical cosmetic slimming product combining tetrahydroxypropyl ethylenediamine, caffeine, carnitine, forskolin and retinol. The Ex vivo study on skin explants showed that caffeine and forskolin both stimulated glycerol release and demonstrates for the first time that retinol and carnitine in combination synergistically stimulated keratinocyte proliferation, which leads to an increase epidermal thickness. The double-blind, randomized, placebo-controlled clinical study associating circumference measurements on five selected parts of the body, cutaneous hydration measurements as well as blinded expert grading of skin aspect was conducted on 78 women who applied the product or placebo twice daily for 12 consecutive weeks. After 4 weeks of twice-daily application of the product, significant reductions in circumference of abdomen, hips-buttocks and waist were already observed. Improvements concerned all the measured body parts after 12 weeks. Orange peel and stubborn cellulite decreased significantly from 4 weeks of treatment and tonicity improved from 8 weeks, demonstrating that the product improved skin aspect. At the end of the study, eight parameters of the thirteen evaluated were significantly improved in the active group and compared with placebo.

RESUMO

Delayed reporting of health data may hamper the early detection of infectious diseases in surveillance systems. Furthermore, combining multiple data streams, e.g. aiming at improving a system's sensitivity, can be challenging. In this study, we used a Bayesian framework where the result is presented as the value of evidence, i.e. the likelihood ratio for the evidence under outbreak versus baseline conditions. Based on a historical data set of routinely collected cattle mortality events, we evaluated outbreak detection performance (sensitivity, time to detection, in-control run length) under the Bayesian approach among three scenarios: presence of delayed data reporting, but not accounting for it; presence of delayed data reporting accounted for; and absence of delayed data reporting (i.e. an ideal system). Performance on larger and smaller outbreaks was compared with a classical approach, considering syndromes separately or combined. We found that the Bayesian approach performed better than the classical approach, especially for the smaller outbreaks. Furthermore, the Bayesian approach performed similarly well in the scenario where delayed reporting was accounted for to the scenario where it was absent. We argue that the value of evidence framework may be suitable for surveillance systems with multiple syndromes and delayed reporting of data.

RESUMO

Population trends for commensal rodents are the subject of interest and speculation but accurate data are rarely available. Here we report data from a 15-year systematic survey of rats and mice in English dwellings and present national-level estimates of prevalence for 1996-2010. We found evidence for peaks in prevalence of mice inside and rats around dwellings in 2002 and 2008. Models containing twelve variables relating to the dwelling and local area explained some but not all of the variation in prevalence. Older dwellings, those in rural areas, those with litter, drainage faults and pets or other animals outdoors tended to have higher levels of rodent prevalence. Regional differences were found but there were no seasonal trends apart from lower prevalence of mice during summer. Rodent prevalence was generally higher in rented (compared to owner-occupied) dwellings, although apparently not due to reduced tendency to carry out rodent control. The percentage of households having taken some form of action against active rodent problems varied according to prevalence at the national level, and therefore appropriate data on number of rodent control treatments carried out each year could likely act as a useful index of household rodent prevalence.

RESUMO

BACKGROUND: Nefopam is a centrally acting analgesic which has a theoretical risk of stopping lactation due to its anticholinergic and dopaminergic effects. The aim of this study was to evaluate the effect of nefopam on lactation and to investigate potential adverse effects on newborns. METHODS: Seventy-two women, scheduled to undergo a caesarean delivery under spinal anaesthesia and wanting to breastfeed, were randomised to one of two groups: nefopam (20mg, six hourly) or paracetamol (1g, six hourly). In both groups, postoperative analgesia was supplemented with ketoprofen (50mg, six hourly) in conjunction with intrathecal morphine 0.1mg. The primary outcome was onset of lactation, estimated by weighing the newborns before and after feeding; by maternal perception of breast fullness and based on serum prolactin concentration 48hours postpartum. Secondary outcomes were neonatal adverse effects evaluated by neurobehavioural score at 12, 24, 48, and 72hours after birth. Statistical analyses were performed using Chi-squared, Fisher exact and Student t tests as appropriate. P<0.05 was considered statistically significant. RESULTS: The difference in the weight of the newborn before and after each feed, maternal perception of breast fullness and serum prolactin did not significantly differ between groups. The volume of artificial milk given to newborns of mothers in the nefopam group on days two and three was significantly greater than for the paracetamol group. Neurobehavioural scores were comparable at each time point. CONCLUSION: Nefopam does not appear to delay the onset of lactation or present any clear risk to the newborn.

RESUMO

Over the last couple of decades, the UK experienced a substantial increase in the incidence and geographical spread of bovine tuberculosis (TB), in particular since the epidemic of foot-and-mouth disease (FMD) in 2001. The initiation of the Randomized Badger Culling Trial (RBCT) in 1998 in south-west England provided an opportunity for an in-depth collection of questionnaire data (covering farming practices, herd management and husbandry, trading and wildlife activity) from herds having experienced a TB breakdown between 1998 and early 2006 and randomly selected control herds, both within and outside the RBCT (the so-called TB99 and CCS2005 case-control studies). The data collated were split into four separate and comparable substudies related to either the pre-FMD or post-FMD period, which are brought together and discussed here for the first time. The findings suggest that the risk factors associated with TB breakdowns may have changed. Higher Mycobacterium bovis prevalence in badgers following the FMD epidemic may have contributed to the identification of the presence of badgers on a farm as a prominent TB risk factor only post-FMD. The strong emergence of contact/trading TB risk factors post-FMD suggests that the purchasing and movement of cattle, which took place to restock FMD-affected areas after 2001, may have exacerbated the TB problem. Post-FMD analyses also highlighted the potential impact of environmental factors on TB risk. Although no unique and universal solution exists to reduce the transmission of TB to and among British cattle, there is an evidence to suggest that applying the broad principles of biosecurity on farms reduces the risk of infection. However, with trading remaining as an important route of local and long-distance TB transmission, improvements in the detection of infected animals during pre- and post-movement testing should further reduce the geographical spread of the disease.

RESUMO

Cerebral hypoxia-ischemia (HI) is an important cause of perinatal brain damage in the term newborn. The areas most affected are the parasagittal regions of the cerebral cortex and, in severe situations, the basal ganglia. The aim of this study was to show that the newborn piglet model can be used to produce neuropathology resulting from moderate HI insult and to monitor damage for 7 days. Two acute cerebral HI were induced in newborn Large White piglets by reducing the inspired oxygen fraction to 4% and occluding the carotid arteries. Newborn piglets were resuscitated, extubated and monitored for 7 days. (31)P magnetic resonance spectroscopy (MRS) offers the ability to monitor the severity of the HI insults. Lactate (Lac) was detected in the HI group at 2 h, 3 days and 5 days after insult by (1)H MRS. Lac/n-acetylaspartate and Lac/choline and Lac/creatine ratios increased significantly (p < 0.01) in the HI group 2 h after HI insults and remained high over 7 days. For the HI group, mean T(2) values increased significantly in the parietal white matter (subcortical) for 5 days after HI insult [117.5 (+/-7.4) to 158.5 (+/-19.2) at T+3 days, 167.7 (+/-15.4) at T+5 days and 160.9 (+/-10.1) at T+7 days (p < 0.01)]. This newborn piglet model of moderate HI brain injury with reproducible cerebral damage could be use as reference for the study of neuroprotective strategy for a period of 7 days.

RESUMO

An anatomo-clinical entity, fibrous constrictive endocarditis can betreated srugically, and we carried out this procedure for the first time in 1971, since when we have used it seven times; it consists of an internal stripping of one or both centricles, with removal of one or both the mitral and tricuspid valves. The results were encouraging in the first two cases, and so good in the succeeding ones that this endocardial resection could be put forward as the treatment of choice for a condition whose aetiology is still unclear.
