Rare diseases and space health: optimizing synergies from scientific questions to care.

Knowledge transfer among research disciplines can lead to substantial research progress. At first glance, astronaut health and rare diseases may be seen as having little common ground for such an exchange. However, deleterious health conditions linked to human space exploration may well be considered as a narrow sub-category of rare diseases.

Patient Preference Between Cabazitaxel and Docetaxel for First-line Chemotherapy in Metastatic Castration-resistant Prostate Cancer: The CABADOC Trial.

Background: The taxanes docetaxel and cabazitaxel prolong overall survival for men with metastatic castration-resistant prostate cancer (mCRPC), with cabazitaxel approved in the postdocetaxel setting only. Recent data suggest they have similar efficacy but a different safety profile in the first-line mCRPC setting.

Objective: To assess patient preference between docetaxel and cabazitaxel among men who received one or more doses of each taxane and did not experience progression after the first taxane.

A case of eagle fern (Pteridium aquilinum) poisoning on a pig farm.

Background: Free-range pig farming represents a minor proportion of pig production in France but is attracting an increasing number of farmers because of societal expectations and the opportunity to use pasture-grazed forage. However, this type of farming faces several challenges, including biosecurity, parasitic management, and contact with wild fauna and pathogenic flora.

Case Presentation: Two Gascon pigs raised on an outdoor fattening farm in the Hautes-Pyrenees department of France were submitted after sudden death for necropsy at the National Veterinary School of Toulouse.

Polymorphism of the alpha-1-fucosyltransferase (FUT1) gene in several wild boar (Sus scrofa) populations in France and link to edema disease.

Background: In 2013, an outbreak of edema disease in a population of wild boars (Sus scrofa) took place. This was the first described case as reported worldwide. An enterotoxigenic Escherichia coli (presenting the Stx2e and F18 virulence factors) is the main pathogen for this disease in wild boar.

Unusual acute neonatal mortality and sow agalactia linked with ergot alkaloid contamination of feed.

Background: An increase in the occurrence of ergot alkaloid contamination has been observed in Europe in recent years. The typical clinical signs of pig ergot poisoning are impaired growth, agalactia and, sometimes, gangrene. Opportunities for reporting exposure doses associated with clinical signs in animals under field conditions are rare.

Evaluation of porcine reproductive and respiratory syndrome stabilization protocols in 23 French Farrow-to-finish farms located in a high-density swine area.

Background: Porcine reproductive and respiratory syndrome virus (PRRSV) is responsible for reproductive disorders in sows and respiratory problems in pigs, and has a major economic impact. Controlling PRRSV is therefore a priority for the swine industry. Stabilization of a herd, defined as the production of PRRSV-negative pigs at weaning from seropositive sows, is a common method of control, and different protocols have been described in the literature to achieve this stabilization.

Review: Assessment of completeness of reporting in intervention studies using livestock: an example from pain mitigation interventions in neonatal piglets.

Accurate and complete reporting of study methods, results and interpretation are essential components for any scientific process, allowing end-users to evaluate the internal and external validity of a study. When animals are used in research, excellence in reporting is expected as a matter of continued ethical acceptability of animal use in the sciences. Our primary objective was to assess completeness of reporting for a series of studies relevant to mitigation of pain in neonatal piglets undergoing routine management procedures.

Porcine health management - the pig in a central position.

We are proud to launch a new open access journal, entitled Porcine Health Management (PHM). This new journal, which puts the pig in a central position, has been jointly established by the European College of Porcine Health and Management and the European Association of Porcine Health Management. PHM is interested in publishing articles of high quality and novelty, but we also consider research results of more general interest and clinical features to the readers.

Pain management in the neonatal piglet during routine management procedures. Part 2: grading the quality of evidence and the strength of recommendations.

Piglets reared in swine production in the USA undergo painful procedures that include castration, tail docking, teeth clipping, and identification with ear notching or tagging. These procedures are usually performed without pain mitigation. The objective of this project was to develop recommendations for pain mitigation in 1- to 28-day-old piglets undergoing these procedures.

Variations in the vulvar temperature of sows during proestrus and estrus as determined by infrared thermography and its relation to ovulation.

The prediction of ovulation time is one of the most important and yet difficult processes in pig production, and it has a considerable impact on the fertility of the herd and litter size. The objective of this study was to assess the vulvar skin temperature of sows during proestrus and estrus using infrared thermography and to establish a possible relationship between the variations in vulvar temperature and ovulation. The experimental group comprised 36 crossbred Large White × Landrace females, of which 6 were gilts and 30 were multiparous sows.

Swine influenza surveillance in East and Southeast Asia: a systematic review.

East and Southeast Asia are important pig- and poultry-producing areas, where the majority of production takes place on small-scale farms with low biosecurity levels. This systematic review synthesizes data on swine influenza virology, serology and epidemiology in East and Southeast Asia. A total of 77 research articles, literature reviews and conference papers were selected and analyzed from 510 references retrieved from PubMed and ISI Web of KnowledgeSM.

Rule 3,000: a more reliable precursor to perceive vestibular schwannoma on MRI in screened asymmetric sensorineural hearing loss.

Nine different definitions of asymmetric sensorineural hearing loss (SNHL) have been reported in literature. The objectives of this study are to: (1) compare all these definitions of asymmetric SNHL; (2) measure the agreement between these definitions in detecting vestibular schwannoma (VS); and (3) determine the strongest association between an asymmetric SNHL definition and positive VS on magnetic resonance imaging (MRI). The study is a retrospective chart review in a tertiary care center.

Broadening GHG accounting with LCA: application to a waste management business unit.

In an effort to obtain the most accurate climate change impact assessment, greenhouse gas (GHG) accounting is evolving to include life-cycle thinking. This study (1) identifies similarities and key differences between GHG accounting and life-cycle assessment (LCA), (2) compares them on a consistent basis through a case study on a waste management business unit. First, GHG accounting is performed.

Asymmetric hearing loss: rule 3,000 for screening vestibular schwannoma.

Objective: To assess the diagnostic yield of audiograms associated to electronystagmography (ENG) for screening vestibular schwannomas (VSs), to determine what definition of asymmetric sensorineural hearing loss (ASNHL) fits best for the diagnosis of VS, and to determine if cochleovestibular symptoms and atherosclerotic potential risk factors play a role in the VS screening.

Study Design: Retrospective chart review in a tertiary care center.

Methods: One hundred twenty-two patients were included in the study and divided into 2 groups: 1) patients presenting a VS (n = 74) and 2) patients without VS (n = 48).

Prevalence of selected enteropathogenic bacteria in Hungarian finishing pigs.

The aim of this study was to obtain prevalence estimates about the most important enteropathogenic bacteria: Lawsonia intracellularis, Brachyspira hyodysenteriae, Brachyspira pilosicoli, Salmonella enterica and Clostridium perfringens A and C in Hungarian farrow-to-finish pig herds. A total of 31 herds were selected, from where six pooled faecal samples, each containing three individual rectal faecal samples were collected from fattening pigs of 5-6 months of age. All 186 samples were examined by polymerase chain reaction (PCR) for the presence of the pathogens mentioned above.

Effect of vitamin supplements on some aspects of performance, vitamin status, and semen quality in boars.

The aim of the present study was to determine the effects of dietary supplements of vitamins on vitamin status, libido, and semen characteristics in young boars under normal and intensive semen collection. Sixty Landrace, Yorkshire, and Duroc boars were allocated randomly from 6 to 10 mo of age to one of the following diets: 1) basal diet (industry level) for minerals and vitamins (Control, n = 15); 2) basal diet supplemented with vitamin C (ASC, n = 15); 3) basal diet supplemented with fat-soluble vitamins (FSV, n = 15); and 4) basal diet supplemented with water-soluble vitamins (WSV, n = 15). After puberty (approximately 12 mo of age), semen was collected at a regular frequency (three times every 2 wk) for 5 wk.

Effects of repeated cross-fosterings on preweaning behavior and growth performance of piglets and on maternal behavior of sows.

Extensive cross-fostering is widely used in early-weaning units in order to standardize and improve body weight at weaning. However, young suckling piglets develop teat fidelity and repeated cross-fosterings could go against this behavior. This experiment was therefore conducted to compare the behavior and growth of 13 control and 14 fostered litters.

Epidemiological, clinical and control investigations on field porcine coccidiosis: clinical, epidemiological and parasitological paradigms?

For several reasons, we are convinced that the parasitologist community must look again at porcine neonatal coccidiosis. We find it surprising that this disease is seldom addressed, and that assumptions are not always supported by clinico-epidemiological analysis. For example, the relationship between diarrhoea and the excretion of oocysts during experimental infection versus field infection is not questioned.

Relationships between individual behavioural traits and post-weaning growth in segregated early-weaned piglets.

Piglets' individual behavioural traits have been studied in the last decade but no report has linked these traits with growth. This experiment was conducted to determine if behavioural traits of segregated early-weaned piglets could be good predictors of their post-weaning growth and, thus, help to predict their adaptation to early weaning. Following segregated early weaning at 17+/-1 days old, 252 piglets were submitted to three tests between 20 and 25 days of age: open-field, reaction to humans and rank order based on competition for a restricted-access feeder.

[The effect of health care settings on children's immunization status].

The objective of this study was to determine the effect of practice settings (CLSC and private office) and family characteristics (mother's age and education, children's rank in families) on children's immunization status and adherence to the immunization schedule. The study population was composed of 209 children born in 1991 and residing in the Regional Municipal County of Montmagny, Quebec. After adjusting for mother's education, those children vaccinated in a private office were at 13.
