Over the past decade the use of long-lasting insecticidal nets (LLINs), in combination with improved drug therapies, indoor residual spraying (IRS) and better health infrastructure, has helped reduce malaria in many African countries for the first time in a generation. However, insecticide resistance in the vector is an evolving threat to these gains. We review emerging and historical data on behavioural resistance in response to LLINs and IRS. Overall the current literature suggests behavioural and species changes may be emerging, but the data are sparse and, at times unconvincing. However, preliminary modelling has demonstrated that behavioural resistance could have significant impacts on the effectiveness of malaria control. We propose seven recommendations to improve understanding of resistance in malaria vectors. Determining the public health impact of physiological and behavioural insecticide resistance is an urgent priority if we are to maintain the significant gains made in reducing malaria morbidity and mortality.

Introduction and Aims: The Indigenous Risk Impact Screen (IRIS) is a validated culturally appropriate and widely used tool in the community for assessing substance use and mental disorder. This research aimed to assess the utility of this tool in an Indigenous prison population. Design and Methods: The study used data collected from a cross-sectional study of mental health among indigenous inmates in Queensland custodial centres (n=395, 84% male). Participants were administered a modified version of the IRIS, and ICD-10 diagnoses of substance use, depressive and anxiety disorders obtained using the Composite International Diagnostic Interview (CIDI). The concurrent validity of the modified IRIS was assessed against those of the CIDI. Results: 312 people screened as high risk for a substance use disorder and 179 were high risk for mental problems. 73% of males and 88% of females were diagnosed with a mental disorder. The IRIS was an effective screener for substance use disorders, with high sensitivity (Se) of 94% and low specificity (Sp) of 33%. The screener was less effective in identifying depression (Se 82%, Sp 59%) and anxiety (Se 68%, Sp 60%). Discussion: The IRIS is the first culturally appropriate screening instrument to be validated for the risk of drug and alcohol and mental disorder among Indigenous adults in custody. Conclusions: This study demonstrated that the IRIS is a valid tool for screening of alcohol and drug use risk among an incarcerated Indigenous population. The IRIS could offer an opportunity to improve the identification, treatment and health outcomes for incarcerated Indigenous adults.

Dysphagia is a common and problematic symptom characterised by varying degrees of difficulty swallowing food, fluids and medicines of differing consistencies. International primary care based studies have identified that between 1 in 4 and 1 in 5 patients have some form of dysphagia, it can affect medicines taking behaviour and healthcare professionals are largely unaware of this1,2. Similar research has not been undertaken in the UK. Adherence related pharmacy based services in the UK provide an opportunity for community pharmacists to identify the problem and facilitate better medicines use. The aim of this pilot study was to estimate the level of patient reported dysphagia in older persons using community pharmacies in the UK, describe how it affects their medicine taking behaviour and identify whether advanced pharmacy services are related to improved awareness of this.

Rare-earth ions (Eu3+, Tb3+) doped AMoO(4) (A = Sr, Ba) particles with uniform morphologies were successfully prepared through a facile solvothermal process using ethylene glycol (EG) as protecting agent. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectra (XPS), Fourier transform infrared spectroscopy (FT-IR), photoluminescence (PL) spectra and the kinetic decays were performed to characterize these samples. The XRD results reveal that all the doped samples are of high purity and crystallinity and assigned to the tetragonal scheelite-type structure of the AMoO(4) phase. It has been shown that the as-synthesized SrMoO4:Ln and BaMoO4:Ln samples show respective uniform pea nut-like and oval morphologies with narrowsize distribution. The possible growth process of the AMoO(4):Ln has been investigated in detail. The EG/H2O volume ratio, reaction temperature and time have obvious effect on themorphologies and sizes of the as-synthesized products.

Rationale, aims and objectives Continuing health education is essential but challenged. in 2006, the Brazilian Cochrane Center, in collaboration with the Ministry of Health, launched a mass teaching initiative in evidence-based health care (EBH) for public-sector professionals via teleconferencing. This 152-hour, interactive EBH course has enrolled over 4500 professionals. This study aimed to assess the acquisition EBH knowledge and skills, as well as the attitudes and perceptions of a sample of students enrolled in the 2009 course via teleconferencing.Methods This prospective cohort study analyzed three aspects of this 152-hour EBH course that recruited 1040 volunteer participants, all public health sector employees working in 131 different hospitals or health agencies. Pre- and post-course tests using a modified version of the Berlin questionnaire with 20 multiple-choice questions were used to examine knowledge acquisition in a sample of 297 students. Tests were completed upon registration and at course completion. the research projects submitted by 872 participants were evaluated to assess skill acquisition. Answers to an anonymous survey assessed the attitudes and perceptions of 914 participants.Results There was a significant increase in knowledge from baseline to course completion (mean scores 8.2 +/- 3.3 versus 13.7 +/- 3.0, P < 0.001). Over 90% of the research projects were judged to be of adequate quality (appropriate rationale for the study, well-formulated research question and feasible execution); over 95% of the participants were satisfied with the course.Conclusion the Brazilian EBH course via teleconference improved the knowledge and skills of public-sector health professionals and was approved by the vast majority of students.

Cette recherche vise à augmenter les connaissances sur le processus d’insertion professionnelle des nouveaux directeurs et directeurs adjoints du primaire et du secondaire au Québec lors de la première année en fonction. Pour mieux connaître cette étape de la vie professionnelle, quatre dimensions du processus d’insertion professionnelle ont été étudiées : la nature de la tâche, le contexte d’exercice, le soutien et l’accompagnement et les caractéristiques motivationnelles. Le sentiment d’empowerment des nouveaux gestionnaires a été étudié simultanément afin d’examiner leur motivation à exercer la nouvelle fonction. La question générale de la recherche était de savoir si la mesure du sentiment d’empowerment utilisé pour traiter de la motivation pouvait apporter de l’information sur la façon dont se vit le processus d’insertion professionnelle des nouveaux directeurs et directeurs adjoints d’établissement d’enseignement. Les données ont été recueillies auprès de dix nouveaux directeurs et directeurs adjoints d’établissement. Une conception de l’insertion professionnelle en tant que processus ayant été retenue, chaque participant a été rencontré à trois moments au cours de l’année scolaire, soit quelques semaines après l’entrée en fonction, au milieu de l’année et à la fin de celle-ci. Lors de chaque rencontre, les participants ont été interrogés à l’aide d’une grille d’entrevue semi-dirigée sur les quatre dimensions du processus d’insertion professionnelle mentionnées précédemment. Ils complétaient par la suite un questionnaire pour mesurer le sentiment d’empowerment. Ce questionnaire est une adaptation validée par Boudreault (1990) d’un outil développé par Tymon (1988). La recherche tend à confirmer l’utilité du sentiment d’empowerment comme source d’information sur le déroulement du processus d’insertion professionnelle. Ainsi, des relations semblent possibles entre le sentiment d’empowerment et certains aspects étudiés. Il s’agit de relations qu’il faudra cependant analyser avec de plus grands échantillons pour les valider. Tout d’abord, concernant la nature de la tâche, les constats indiquent que les directeurs adjoints affichant les meilleurs sentiments d’empowerment géraient moins de dossiers différents et que la plupart des dossiers dont ils étaient responsables faisaient appel à des habiletés développées antérieurement lors d’affectation intérimaire ou lors de leur participation à des comités à titre d’enseignants. De plus, ces participants avaient moins de gestion de personnel à effectuer, et particulièrement au regard du personnel de soutien. Ensuite, une tendance marquée a ensuite été constatée en ce qui concerne le soutien et l’accompagnement. Il est apparu que les participants (directeurs et directeurs adjoints) avec les meilleurs sentiments d’empowerment étaient ceux qui bénéficiaient du meilleur soutien et accompagnement de leur supérieur immédiat. Puis, en ce qui a trait aux caractéristiques motivationnelles, les participants exprimant les meilleurs sentiments d’empowerment se sentaient plus capables d’accomplir leur tâche et remettaient moins en question l’exercice de leur fonction. La recherche a indiqué d’autres relations possibles entre le sentiment d’empowerment et certains aspects des dimensions de l’insertion professionnelle, qui bien que moins marquées dans l’échantillon, mériteraient d’être approfondies dans des travaux futurs. Il s’agit de la relation entre le sentiment d’empowerment et le climat organisationnel de l’établissement, de la marge de manœuvre consentie dans l’exercice de la fonction et de la motivation des directeurs adjoints à postuler à un poste de directeur. Finalement, la recherche a mis en lumière la conviction des nouveaux directeurs de vivre une nouvelle phase d’insertion professionnelle et la différence entre les tâches des directeurs adjoints du primaire et ceux du secondaire.
