The Joint Observation in Neonatology and Neurodevelopmental Outcome of Preterm Infants at Six Months Corrected Age: Secondary Outcome Data from a Randomised Controlled Trial.

This study aimed to evaluate the impact of a standardised joint observation (JOIN) performed in the neonatal intensive care unit (NICU) on the neurodevelopment of preterm infants at six months corrected age (CA) compared with a preterm control group. In this monocentric interventional randomised controlled trial, we allocated 76 mothers and their preterm neonates to either JOIN, an early one-session intervention, or standard care during the NICU hospitalisation. The neurodevelopment of the preterm infants was assessed by standardised developmental tests at six months CA and compared between the intervention and the control groups. This randomised controlled trial was registered on clinicaltrials.gov (NCT02736136) in April 2016. Sixty-five infants underwent neurodevelopmental assessment at six months CA. There were no significant differences between the two groups in neurodevelopmental outcome measures. The JOIN intervention was not associated with significant improvement in neurodevelopment at six months CA in preterm infants

Illness tracking in SARS-CoV-2 tested persons using a smartphone app: a non-interventional, prospective, cohort study

There are few data on the range and severity of symptoms of SARS-CoV-2 infection or the impact on life quality in infected, previously healthy, young adults such as Swiss Armed Forces personnel. It is also unclear if an app can be used to remotely monitor symptoms in persons who test positive. Using a smartphone app called ITITP (Illness Tracking in Tested Persons) and weekly pop-up questionnaires, we aimed to evaluate the spectrum, duration, and impact of symptoms reported after a positive SARS-CoV-2 test according to sex, age, location, and comorbidities, and to compare these to responses from persons who tested negative. We followed up 502 participants (57% active participation), including 68 (13.5%) positive tested persons. Hospitalisation was reported by 6% of the positive tested participants. We found that positives reported significantly more symptoms that are typical of COVID-19 compared to negatives. These symptoms with odds ratio (OR > 1) were having difficulty breathing (OR 3.35; 95% CI: 1.16, 9.65; p = 0.03), having a reduced sense of taste (OR 5.45; 95% CI: 1.22, 24.34; p = 0.03) and a reduced sense of smell (OR 18.24; 95% CI: 4.23, 78.69; p < 0.001). Using a random forest model, we showed that tiredness was the single symptom that was rated as having a significant impact on daily activities, whereas the other symptoms, although frequent, had less impact. The study showed that the use of an app was feasible to remotely monitor symptoms in persons infected with SARS-CoV-2 and could be adapted for other settings and new pandemic phases such as the current Omicron wave

Intoxicación por Brunfelsia australis en caninos: confirmación mediante identificación del vegetal en muestras biológicas

Los animales domésticos se hallan expuestos a diferentes sustancias que pueden provocar intoxicaciones leves a graves. Las producidas por la ingestión de plantas son comunes en grandes animales pero también pueden constituir un problema para mascotas. Los veterinarios en general no están familiarizados con las plantas nativas de su zona geográfica y el daño potencial que pueden causar. El género Brunfelsia (“jazmín paraguayo”, Solanaceae) incluye arbustos atractivos por sus flores que cambian de color púrpura a blanco, circunstancia que les otorga el nombre común de “ayer, hoy y mañana”. La intoxicación provocada por esta planta se debe a su elevada concentración de alcaloides tropánicos. En este trabajo se presentan dos casos de intoxicación por Brunfelsia australis en caninos, uno de ellos fatal. El canino que murió presentó signos neurológicos y vómitos que contenían material vegetal con pequeños fragmentos similares a frutos y semillas de color marrón oscuro. El otro canino también presentó signos neurológicos y diarrea de color verde que contenía material vegetal con fragmentos de hojas y tallos. Ambas muestras fueron examinadas por observación macroscópica/microscópica y comparación con patrones de referencia, comprobándose que correspondían a B. australis. Además de los hallazgos clínicos, el análisis de muestras biológicas constituye un método complementario para el diagnóstico de intoxicaciones provocadas por plantas. Para el caso particular de B. australis se comprueba que la ingestión de frutos puede resultar fatal y que la ingestión de hojas y ramas produciría una intoxicación menos grave. Se destaca la necesidad de que los profesionales se familiaricen con la morfología y composición química de las plantas ornamentales tóxicas propias de su región, para poder instaurar el tratamiento adecuado

Martensitic transition and magnetoresistance in a Cu-Al-Mn shape memory alloy. Influence of aging

We have studied the effect of ageing within the miscibility gap on the electric, magnetic and thermodynamic properties of a non-stoichiometric Heusler Cu-Al-Mn shape-memory alloy, which undergoes a martensitic transition from a $bcc$-based ($\beta$-phase) towards a close-packed structure ($M$-phase). Negative magnetoresistance which shows an almost linear dependence on the square of magnetization with different slopes in the $M$- and $\beta$-phases, was observed. This magnetoresistive effect has been associated with the existence of Mn-rich clusters with the Cu$_2$AlMn-structure. The effect of an applied magnetic field on the martensitic transition has also been studied. The entropy change between the $\beta$- and $M$-phases shows negligible dependence on the magnetic field but it decreases significantly with annealing time within the miscibility gap. Such a decrease is due to the increasing amount of Cu$_2$MnAl-rich domains that do not transform martensitically.Comment: 9 pages, 9 figures, accepted for publication in PR

Transmission phenotype of mycobacterium tuberculosis strains is mechanistically linked to induction of distinct pulmonary pathology

In a study of household contacts (HHC), households were categorized into High (HT) and Low (LT) transmission groups based on the proportion of HHC with a positive tuberculin skin test. The Mycobacterium tuberculosis (Mtb) strains from HT and LT index cases of the households were designated Mtb-HT and Mtb-LT, respectively. We found that C3HeB/FeJ mice infected with Mtb-LT strains exhibited significantly higher bacterial burden compared to Mtb-HT strains and also developed diffused inflammatory lung pathology. In stark contrast, a significant number of mice infected with Mtb-HT strains developed caseating granulomas, a lesion type with high potential to cavitate. None of the Mtb-HT infected animals developed diffused inflammatory lung pathology. A link was observed between increased in vitro replication of Mtb-LT strains and their ability to induce significantly high lipid droplet formation in macrophages. These results support that distinct early interactions of Mtb-HT and Mtb-LT strains with macrophages and subsequent differential trajectories in pathological disease may be the mechanism underlying their transmission potential.publishersversionpublishe

Supporting reasonable adjustments for learners with disabilities in physical education: An investigation into teacher’s perceptions of one online tool

This study sets out to investigate physical education (PE) teachers’ perceptions of the use of an online professional development resource to support making reasonable adjustment for learners with disability. The Equality Act (2010) called on all UK schools to ensure access to PE was equitable for all learners. This means schools have to adopt strategies for making reasonable adjustments so as not to disadvantage learners with any special educational need and disability. Teachers report that they are working towards an inclusive classroom; however, parents of learners with disabilities report that there remains a lack of opportunities for their children to engage with activity. Using purposive sampling, participants were selected for the study after which they were asked to complete a continuing professional development online training course on the subject of making reasonable adjustments for learning with disabilities. Through one-to-one interviews, qualitative data were collected and analysed through thematic analysis. The findings indicated that the online resource was greeted positively by staff and not only supported the PE teachers but also increased their awareness of different approaches to making reasonable adjustments. The findings also indicated that the issue of making reasonable adjustments and the use of the online development tool need to be driven from the school senior leadership team if it is to have value for the whole school community

Lack of association between serological evidence of past Coxiella burnetii infection and incident ischaemic heart disease: nested case-control study

BACKGROUND: Coxiella burnetii causes the common worldwide zoonotic infection, Q fever. It has been previously suggested that patients who had recovered from acute Q fever (whether symptomatic or otherwise) may be at increased risk of ischaemic heart disease. We undertook this study to determine if past infection with Coxiella burnetii, the aetiological agent of Q fever, is a risk factor for the subsequent development of ischaemic heart disease. METHODS: A nested case-control study within the Prospective Epidemiological Study of Myocardial Infarction (PRIME). The PRIME study is a cohort study of 10,593 middle-aged men undertaken in France and Northern Ireland in the 1990s. A total of 335 incident cases of ischaemic heart disease (IHD) were identified and each case was matched to 2 IHD free controls. Q fever seropositivity was determined using a commercial IgG ELISA method. RESULTS: Seroprevalence of Q fever in the controls from Northern Ireland and France were 7.8% and 9.0% respectively. No association was seen between seropositivity and age, smoking, lipid levels, or inflammatory markers. The unadjusted odds ratio (95% CI) for Q fever seropositivity in cases compared to controls was 0.95 (0.59, 1.57). The relationship was substantially unaltered following adjustment for cardiovascular risk factors and potential confounders. CONCLUSION: Serological evidence of past infection with C. burnetii was not found to be associated with an increased risk of IHD

Recoverable Effects Related to Pseudoelastic Cycling in Cu-Zn-Al Single Crystals

Pseudoelastic cycling of Cu-Zn-Al single crystals has been shown to induce microstructural changes in the material. The mechanical response is also altered. However, some of the observed changes in the mechanical behavior are at least partially recovered at temperatures at which point defects are mobile. In this work results are presented in order to analyze the different contributions associated to the changes of the mechanical behavior during pseudoelastic cycling and in a subsequent ageing stage in the β-phase condition for Cu-Zn-Al single crystals. The magnitudes and kinetics of the recoverable changes are analyzed and compared with the other known phenomena that take place at these temperatures, i.e. the martensite stabilization and the beta phase recovery. Results show that the evolution is not simply related to these phenomena. Additional contributions, like point defects generation during cycling and the effect of dislocation array on the beta phase recovery, need to be considered
