A homeopatia é uma medicina diferente da medicina tradicional, em crescente expansão pelo mundo e fundamentada por três princípios básicos defendidos por Samuel Hahnemann. A homeopatia possui diversas utilizações contudo, segundo a literatura, existe uma desconfiança em relação à sua eficácia. Os objetivos deste trabalho são, em primeiro lugar, reunir de forma organizada e objetiva todos os aspetos importantes relacionados com a homeopatia e em segundo lugar, verificar se o perfil do profissional de farmácia influencia o conhecimento da população sobre os medicamentos homeopáticos bem como estabelecer o perfil dos consumidores de medicamentos homeopáticos. Primeiramente, este trabalho consiste numa revisão que compila a diversa informação sobre homeopatia desde a sua definição, os seus princípios, evolução no mundo e introdução em Portugal, as suas utilizações, a controvérsia e o papel do profissional de farmácia no aconselhamento destes medicamentos. Numa segunda etapa, este trabalho apresenta um estudo transversal, observacional e de coorte realizado a utentes de duas farmácias em que uma delas aconselha diariamente medicamentos homeopáticos ao contrário da outra. Foi aplicado um questionário com perguntas de cariz sociodemográfico e perguntas que permitem avaliar o conhecimento dos utentes sobre esta medicina. Dos 364 indivíduos, 187 (51,4%) afirmam saber o que são medicamentos homeopáticos e destes, 113 (60,4%) possuem efetivamente conhecimento sobre homeopatia, contudo, apenas 129 (35,5%) afirmam já ter tomado estes medicamentos. Tanto o conhecimento como a toma destes medicamentos manifestam-se com maior percentagem de indivíduos na farmácia que aconselha. São os indivíduos mais jovens, com ensino superior, não casados, trabalhadores ativos e com profissão pertencente à área da saúde os que demonstram mais conhecimento sobre o tema. São as mulheres, os indivíduos com ensino superior, com profissão pertencente à área da saúde e com condição socioeconómica média os que demonstraram maior adesão a estes medicamentos. Além disto, este estudo permitiu concluir que o aconselhamento do profissional de farmácia pode ser decisivo no que respeita ao conhecimento e adesão dos utentes a este tipo de medicação. A caracterização do conhecimento e da adesão dos utentes de farmácia comunitária em relação aos medicamentos homeopáticos contribuiu para verificar que tipo de população se interessa por esta área e se a adesão a estes medicamentos é satisfatória de modo a incentivar as farmácias e os profissionais de farmácia a promoverem e aconselharem mais frequentemente medicamentos homeopáticos.

QUESTION Detection and treatment of infections during pregnancy are important for both maternal and child health. The objective of this study was to describe testing practices and adherence to current national guidelines in Switzerland. METHODS We invited all registered practicing obstetricians and gynaecologists in Switzerland to complete an anonymous web-based questionnaire about strategies for testing for 14 infections during pregnancy. We conducted a descriptive analysis according to demographic characteristics. RESULTS Of 1138 invited clinicians, 537 (47.2%) responded and 520 (45.6%) were eligible as they are currently caring for pregnant women. Nearly all eligible respondents tested all pregnant women for group B streptococcus (98.0%), hepatitis B virus (HBV) (96.5%) and human immunodeficiency virus (HIV) (94.7%), in accordance with national guidelines. Although testing for toxoplasmosis is not recommended, 24.1% of respondents tested all women and 32.9% tested at the request of the patient. Hospital doctors were more likely not to test for toxoplasmosis than doctors working in private practice (odds ratio [OR] 2.52, 95% confidence interval [CI] 1.04-6.13, p = 0.04). Only 80.4% of respondents tested all women for syphilis. There were regional differences in testing for some infections. The proportion of clinicians testing all women for HIV, HBV and syphilis was lower in Eastern Switzerland and the Zurich region (69.4% and 61.2%, respectively) than in other regions (range 77.1-88.1%, p <0.001). Most respondents (74.5%) said they would appreciate national guidelines about testing for infections during pregnancy. CONCLUSIONS Testing practices for infections in pregnant women vary widely in Switzerland. More extensive national guidelines could improve consistency of testing practices.

Aliadas aos estudos sobre sustentabilidade, há inúmeras discussões e atitudes para combater consequências do uso irracional dos recursos naturais do planeta. Surge assim o entendimento do consumo, suas influências e alternativas. O indivíduo pode ter hábitos de consumo de forma consumista ou de forma consciente. O consumista é entendido como o oposto dos hábitos do consumidor consciente, sendo levado pelo impulso e pelo estímulo à compra, sem avaliar suas necessidades e impactos futuros. O consumo é de fato indispensável à humanidade. Entretanto, quando aplicado de forma exacerbada e incorreta, pode gerar sérias consequências sociais e/ou ambientais. O consumidor consciente tem a qualificação de avaliar dentre as possibilidades existentes, os impactos que podem ser ocasionados com a aquisição, de tal modo, a minimizar suas consequências e contribuir de alguma forma para uma sociedade mais sustentável. O principal objetivo desta pesquisa foi compreender a aderência dos pesquisados ao comportamento de consumo consciente, bem como avaliar o compartilhamento de informações sobre o tema por pessoas que estão inseridas em alguma rede social na internet, partindo do pressuposto que este é um dos principais meios de comunicação e compartilhamento de informações. Para a pesquisa, foi utilizada a metodologia de análise qualitativa de caráter exploratório e a técnica de entrevistas em profundidade baseada em roteiro semiestruturado. Por meio da análise do conteúdo, a compreensão dos resultados aponta que todos os entrevistados possuem um grau de conhecimento sobre o consumo consciente e a maioria tenta ter algum tipo de ação consciente. Mas, ao mesmo tempo, esses indivíduos podem sofrer influências neste processo principalmente de caráter pessoal, levando à alteração de ação. Com relação ao compartilhamento do tema nas redes sociais na internet, foi possível identificar que grande parte dos entrevistados já teve algum tipo de experiência da situação, mas ainda em pequena escala, com poucas ocorrências. Também acredita-se que o canal pode ser utilizado para a proliferação do tema, o que nos leva à conclusão de que é um canal viável ao compartilhamento. Porém, mediante a ruptura de hábitos, é utilizado para a ocorrência de um maior engajamento por parte dos usuários. A análise apresenta uma compreensão e perspectivas a partir do recorte estudado, abrindo horizonte para novos estudos e aprofundamento das reflexões apresentadas neste trabalho.

Background Medicines reconciliation-identifying and maintaining an accurate list of a patient's current medications-should be undertaken at all transitions of care and available to all patients. Objective A self-completion web survey was conducted for chief pharmacists (or equivalent) to evaluate medicines reconciliation levels in secondary care mental health organisations. Setting The survey was sent to secondary care mental health organisations in England, Scotland, Northern Ireland and Wales. Method The survey was launched via Bristol Online Surveys. Quantitative data was analysed using descriptive statistics and qualitative data was collected through respondents free-text answers to specific questions. Main outcomes measure Investigate how medicines reconciliation is delivered, incorporate a clear description of the role of pharmacy staff and identify areas of concern. Results Forty-two (52 % response rate) surveys were completed. Thirty-seven (88.1 %) organisations have a formal policy for medicines reconciliation with defined steps. Results show that the pharmacy team (pharmacists and pharmacy technicians) are the main professionals involved in medicines reconciliation with a high rate of doctors also involved. Training procedures frequently include an induction by pharmacy for doctors whilst the pharmacy team are generally trained by another member of pharmacy. Mental health organisations estimate that nearly 80 % of medicines reconciliation is carried out within 24 h of admission. A full medicines reconciliation is not carried out on patient transfer between mental health wards; instead quicker and less exhaustive variations are implemented. 71.4 % of organisations estimate that pharmacy staff conduct daily medicine reconciliations for acute admission wards (Monday to Friday). However, only 38 % of organisations self-report to pharmacy reconciling patients' medication for other teams that admit from primary care. Conclusion Most mental health organisations appear to be complying with NICE guidance on medicines reconciliation for their acute admission wards. However, medicines reconciliation is conducted less frequently on other units that admit from primary care and rarely completed on transfer when it significantly differs to that on admission. Formal training and competency assessments on medicines reconciliation should be considered as current training varies and adherence to best practice is questionable.

The Government has established essential principles in order to make significant improvements in the health of the people and has placed an emphasis on shifting care to the primary sening. This research has explored the potential role of the community pharmacist in health promotion in the pharmacy, and at general medical practices. The feasibility of monitoring patients' health status in the community was evaluated by intervention to assess and alter cardiovascular risk factors.68, hypertensive patients, monitored at one surgery, had a change in mean systolic blood pressure from 158.28 to 146.55 mmHg, a reduction of 7.4%, and a change in mean diastolic bood pressure from 90.91 to 84.85 mmHg, a reduction of 6.7%.120 patients, from a cohort of 449 at the major practice, with an initial serum total cholesterol of 6.0+mmol/L, experienced a change in mean value from 6.79 to 6.05 mmol/L, equivalent to a reduction of 10.9%. 86% of this patient cohort showed a decrease in cholesterol concentration. Patients, placed in a high risk category according to their coronary rank score, assessed at the first health screening, showed a consistent and significant improvement in coronary score throughout the study period of two years. High risk and intermediate risk patients showed improvements in coronary score of 52% and 14% respectively. Patients in the low risk group maintained their good coronary score. In some cases, a patient's improvement was effected in liaison with the GP, after a change or addition of medication and/or dosage.Pharmacist intervention consisted of advice on diet and lifestyle and adherence to medication regimes. It was concluded that a pharmacist can facilitate a health screening programme in the primary care setting, and provide enhanced continuity of care for the patient.

In this study I investigated the mechanisms of neuronal network oscillatory activity in rat M1 using pharmacological manipulations and electrical stimulation protocols, employing the in vitro brain slice technique in rat and magnetoencephalography (MEG) in man. Co-application of kainic acid and carbachol generated in vitro beta oscillatory activity in all layers in M1. Analyses indicated that oscillations originated from deep layers and indicated significant involvement of GABAA receptors and gap junctions. A modulatory role of GABAB, NMDA, and dopamine receptors was also evident. Intracellular recordings from fast-spiking (FS) GABAergic inhibitory cells revealed phase-locked action potentials (APs) on every beta cycle. Glutamatergic excitatory regular-spiking (RS) and intrinsically-bursting (IB) cells both received phase locked inhibitory postsynaptic potentials, but did not fire APs on every cycle, suggesting the dynamic involvement of different pools of neurones in the overall population oscillations. Stimulation evoked activity at high frequency (HFS; 125Hz) evoked gamma oscillations and reduced ongoing beta activity. 20Hz stimulation promoted theta or gamma oscillations whilst 4Hz stimulation enhanced beta power at theta frequency. I also investigated the modulation of pathological slow wave (theta and beta) oscillatory activity using magnetoencephalography. Abnormal activity was suppressed by sub-sedative doses of GABAA receptor modulator zolpidem and the observed desynchronising effect correlated well with improved sensorimotor function. These studies indicate a fundamental role for inhibitory neuronal networks in the patterning beta activity and suggest that cortical HFS in PD re-patterns abnormally enhanced M1 network activity by modulating the activity of FS cells. Furthermore, pathological oscillation may be common to many neuropathologies and may be an important future therapeutic target.

One-third of botanical remedies from southern Italy are used to treat skin and soft tissue infections (SST's). Methicillin-resistant Staphylococcus aureus (MRSA), a common cause of SSTIs, is responsible for increased morbidity and mortality from infections. Therapeutic options are limited by antibiotic resistance. Many plants possess potent antimicrobial compounds for these disorders. Validation of traditional medical practices is important for the people who rely on medicinal plants. Moreover, identification of novel antibiotics and anti-pathogenic agents for MRSA is important to global healthcare.^ I took an ethnopharmacological approach to understand how Italian medicinal plants used for the treatment of SSTIs affect MRSA growth and virulence. My hypothesis was that plants used in folk remedies for SSTI would exhibit lower cytotoxicity and greater inhibition of bacterial growth, biofilm formation and toxin production in MRSA than plants used for remedies unrelated to the skin or for plants with no ethnomedical application. The field portion of my research was conducted in the Vulture-Alto Bradano area of southern Italy. I collected 104 plant species and created 168 crude extracts. In the lab, I screened samples for activity against MRSA in a battery of bioassays. Growth inhibition was analyzed using broth microtiter assays for determination of the minimum inhibitory concentration. Interference with quorum-sensing (QS) processes, which mediate pathogenicity, was quantified through RP-HPLC of δ-toxin production. Interference with biofilm formation and adherence was assessed using staining methods. The mammalian cytotoxicity of natural products was analyzed using MTT cell proliferation assay techniques.^ Although bacteriostatic activity was limited, extracts from six plants used in Italian folk medicine (Arundo donax, Ballota nigra, Juglans regia, Leopoldia comosa, Marrubium vulgare, and Rubus ulmifolius ) significantly inhibited biofilm formation and adherence. Moreover, plants used to treat SSTI demonstrated significantly greater anti-biofilm activity when compared to plants with no ethnomedical application. QSI activity was evident in 90% of the extracts tested and extracts from four plants ( Ballota nigra, Castanea saliva, Rosmarinus officinalis, and Sambucus ebulus) exhibited a significant dose-dependent response. Some of the plant remedies for SSTI identified in this study can be validated due to anti-MRSA activity.^

Systemic Arterial Hypertension – SAH – is defined as the syndrome which its main feature is the presence of high tensional levels, associated with alterations of functional or structural levels in the organs that it strikes. Its specific causes are not very well bounded and have an asymptomatic character. Due to its chronicity it requires adherence to the treatment plan in a systematic and permanent manner, implicating in lifestyle changes, combined or not with the use of medication. The personality inventories have been largely used in the lineation of indicative traits of difficulties with the adherence to the treatment. In this sense, developed by Theodore Millon, the Millon Behavioural Medicine Diagnostic – MBMD is an instrument made from the consensus among healthcare professionals, aiming at identifying psychological factors that may compromise medical treatment so that they can be conducted in a way to enable a better adherence. Objective: evaluation of the evidence of validity of the Millon Behavioural Medicine Diagnostic – MBMD for a public of patients with hypertension, aiming at investigating the indicators implicated in the adherence or not to the anti-hypertensive treatment. Method: there was a group of 200 participants in a university hospital in the city of Natal/RN, males and females, ranging from 20 to 70 years old. An interview protocol was administered in order to obtain information about socio-demographic data, clinical history, healthcare habits and way of conducting treatment, and after, the administration of the MBMD followed. Results: by means of Factor Analysis it was verified that the organization proposed by the factors is favorable and it adjusts to the theory, allowing the visualization of other underlying constructs to the scales, with adequate adjustment indexes and satisfactory Cronbach’s alpha indicators. Besides, the MBMD revealed itself sensitive to the intragroup differences relative to the sex, age, schooling, marital status, profession, income, SAH history, diagnostic time, medication use, comorbidity presence, hyposodic diet, social support and adherence criteria variables. The utilization of such instrument in the evaluation of the adherence to the anti-hypertensive treatment show, therefore, indicators of validity.

Advanced doping technologies are key for the continued scaling of semiconductor devices and the maintenance of device performance beyond the 14 nm technology node. Due to limitations of conventional ion-beam implantation with thin body and 3D device geometries, techniques which allow precise control over dopant diffusion and concentration, in addition to excellent conformality on 3D device surfaces, are required. Spin-on doping has shown promise as a conventional technique for doping new materials, particularly through application with other dopant methods, but may not be suitable for conformal doping of nanostructures. Additionally, residues remain after most spin-on-doping processes which are often difficult to remove. In-situ doping of nanostructures is especially common for bottom-up grown nanostructures but problems associated with concentration gradients and morphology changes are commonly experienced. Monolayer doping (MLD) has been shown to satisfy the requirements for extended defect-free, conformal and controllable doping on many materials ranging from traditional silicon and germanium devices to emerging replacement materials such as III-V compounds but challenges still remain, especially with regard to metrology and surface chemistry at such small feature sizes. This article summarises and critically assesses developments over the last number of years regarding the application of gas and solution phase techniques to dope silicon-, germanium- and III-V-based materials and nanostructures to obtain shallow diffusion depths coupled with high carrier concentrations and abrupt junctions.

The general purpose of the two studies reported here was to examine perceptions of team cohesiveness in children aged 9 to 12 years. In Study 1, focus groups were used to examine individual perceptions of cohesion from the perspective of group integration – the group as a totality. In Study 2, open-ended questionnaires were used to examine individual perceptions of cohesion from the perspective of individual attractions to the group. The results showed that children as young as nine years understand the phenomenon known as cohesion. They can discuss the group as a totality, the characteristics of cohesive and non-cohesive teams, and identify the major factors attracting them to and maintaining their involvement in the group. Also, the ability to clearly distinguish between task and social cohesion is present. The results provide insight into the world of child sport and emphasise the importance of group cohesion, affiliation, and other social constructs in children’s involvement and adherence to sport groups

Bakgrund: Glaukom är en kronisk progressiv ögonsjukdom och en av den främsta orsaken till blindhet i världen. Intraockulärt trycksänkande ögondroppar är den vanligaste behandlingsmetoden och följsamhet är mycket viktigt för att minska progression av sjukdomen och risken att bli blind. Tidigare studier har visat att det finns en bristande följsamhet hos patienter med denna behandling. Syfte: Att belysa de faktorer som påverkar patientens följsamhet så att sjuksköterskan ska få en bättre förståelse och kunna vägleda patienten till en bättre följsamhet. Metod: En systematisk litteraturstudie genomfördes baserad på 14 vetenskapliga artiklar med både kvalitativ och kvantitativ ansats. Resultat: Det finns många olika faktorer som påverkar patientens följsamhet i behandlingen med ögondroppar. Det kan vara faktorer som är orsakade av sjukvårdspersonal, av patienten själv samt av miljö/socioekonomiska skäl. Slutsats: Det är viktigt att fortsätta forska på de faktorer som påverkar patienters följsamhet vid ögondroppsbehandling för att sjuksköterskan ska kunna vägleda till en ökad följsamhet.

Au Canada, l’immigration est en augmentation depuis les 25 dernières années. À Québec, entre 1999 et 2008, les Colombiens ont été les plus nombreux à s’établir en tant que réfugiés. Cette augmentation de la diversité de la population n’est pas sans conséquences pour les institutions de santé publique. C’est vrai en particulier pour la protection de la jeunesse dans laquelle les familles migrantes et réfugiées sont surreprésentées. Il est par ailleurs reconnu que le processus d’acculturation entraine une transformation des rôles parentaux. De plus, des recherches ont établi un lien entre l’endossement de certaines valeurs, notamment celles axées sur la famille (familismo) et les rôles sexuels (machismo) pour expliquer les pratiques de parents migrants « latinos » et le rapport qu’elles entretiennent avec les institutions. Cette étude comparative a pour objectif d’explorer, à partir de la parole des premiers concernés, c’est-à-dire les parents, les représentations de leurs pratiques parentales, de la maltraitance et de la protection de la jeunesse. Cette exploration a été réalisée auprès de deux populations de parents : des parents québécois et colombiens ayant migrés à Québec. Un devis mixte impliquant des focus groups a été mis en place. Au total, 49 participants (Québécois : 30, 5 focus groups et Colombiens : 19, 4 focus groups) ont été rencontrés et ont rempli trois questionnaires. Ceux-ci mesurent le familismo, le machismo et l’acculturation. Les scores moyens de familismo, de machismo et d’acculturation ont été intégrés à l’analyse thématique. Il apparait que Québécois et Colombiens se différencient peu quant aux pratiques parentales et aux représentations de la maltraitance et de la protection de la jeunesse. Cependant, la question du développement de l’autonomie et de la réussite des enfants sont deux thèmes majeurs pour lesquels il y a des différences. La place qu’occupe l’État québécois, par l’intermédiaire du système de protection de la jeunesse dans la résolution des conflits, suscite également des discours contrastés. La place que ces personnes prennent dans la société devrait avoir un impact sur le fonctionnement des institutions quant à l’intervention et à la diffusion de l’information par rapport au système de la protection de la jeunesse.

Since 1997, there has been increasing research focused on Muscle Dysmorphia, a condition underpinned by people’s beliefs they have insufficient muscularity, in both the Western and non-western medical and scientific communities. Much of this empirical interest has surveyed nonclinical samples, and there is limited understanding of people with the condition beyond knowledge about their characteristics. Much existing knowledge about people with the condition is unsurprising and inherent in the definition of the disorder, such as dissatisfaction with muscularity and adherence to muscle-building activities. Only recently have investigators started to explore questions beyond these limited tautological findings that may give rise to substantial knowledge advances, such as the examination of masculine and feminine norms. There is limited understanding of additional topics such as etiology, prevalence, nosology, prognosis, and treatment. Further, the evidence is largely based on a small number of unstandardized case reports and descriptive studies (involving small samples), largely confined to Western (North American, British, and Australian) males. Although much research has been undertaken since the term Muscle Dysmorphia entered the psychiatric lexicon in 1997, there remains tremendous scope for knowledge advancement. A primary task in the short term is for investigators to examine the extent that the condition exists among well-defined populations to help determine the justification for research funding relative to other public health issues. A greater variety of research questions and designs may contribute to a broader and more robust knowledge base than currently exists. Future work will help clinicians assist a group of people whose quality of life and health is placed at risk by their muscular preoccupation.

Introduction: Reporting guidelines (e. g. CONSORT) have been developed as tools to improve quality and reduce bias in reporting research findings. Trial registration has been recommended for countering selective publication. The International Committee of Medical Journal Editors (ICMJE) encourages the implementation of reporting guidelines and trial registration as uniform requirements (URM). For the last two decades, however, biased reporting and insufficient registration of clinical trials has been identified in several literature reviews and other investigations. No study has so far investigated the extent to which author instructions in psychiatry journals encourage following reporting guidelines and trial registration. Method: Psychiatry Journals were identified from the 2011 Journal Citation Report. Information given in the author instructions and during the submission procedure of all journals was assessed on whether major reporting guidelines, trial registration and the ICMJE's URM in general were mentioned and adherence recommended. Results: We included 123 psychiatry journals (English and German language) in our analysis. A minority recommend or require 1) following the URM (21%), 2) adherence to reporting guidelines such as CONSORT, PRISMA, STROBE (23%, 7%, 4%), or 3) registration of clinical trials (34%). The subsample of the top-10 psychiatry journals (ranked by impact factor) provided much better but still improvable rates. For example, 70% of the top-10 psychiatry journals do not ask for the specific trial registration number. Discussion: Under the assumption that better reported and better registered clinical research that does not lack substantial information will improve the understanding, credibility, and unbiased translation of clinical research findings, several stakeholders including readers (physicians, patients), authors, reviewers, and editors might benefit from improved author instructions in psychiatry journals. A first step of improvement would consist in requiring adherence to the broadly accepted reporting guidelines and to trial registration.
