Swiss adolescents' and adults' perceptions of cannabis use : a qualitative study

Abstract Few studies have attempted to investigate the nature of adolescents' and adults' conceptions and perceptions of cannabis use. Our objectives were to explore adolescent and adult perception of use and misuse of cannabis, and their opinions and beliefs about the current legal context and preventive strategies. We used focus group dis¬cussions with four categories of stakeholders: younger (12-15 year old) adolescents, older (16-19 year old) adolescents, parents of teen¬agers and professionals working with young people. In some areas (legal framework, role of the media, importance of early preventive inter¬ventions), we found consensual attitudes and beliefs across the four groups of participants. In all four groups, participants did not have any consensual vision of the risks of cannabis use or the definition of misuse. In the area of the prevention of cannabis use/misuse, while parents focused on the potential role of professionals and the media, thus minimizing their own educa¬tional and preventive role, professionals stressed the importance of parental control and educa¬tion. Within the Swiss context, we conclude there exists an urgent need for information and clari¬fication of the issues linked with cannabis use and misuse directed at parents and professionals.

Diferencias de género en la percepción del logro profesional en especialistas de medicina familiar y comunitaria

BACKGROUND The concept of achievement is important to study the professional development. In medicine there are gender inequalities in career. The purpose was to know and compare the professional achievement's perceptions and attributions of female and male primary care physicians in Andalusia. METHOD Qualitative study with 12 focus groups (October 2009 to November 2010). POPULATION primary care physicians. SAMPLE intentionally segmented by age, sex and health care management. Were conducted by sex: two groups with young physicians, two groups with middle aged and two with health care management. TOTAL: 32 female physician and 33 male physicians. Qualitative content analysis with Nuddist Vivo. RESULTS Female and male physicians agree to perceive internal achievements and to consider aspects inherent to the profession as external achievements. The most important difference is that female physician related professional achievement with affective bond and male physician with institutional merit. Internal attributions are more important for female physician who also highlight the importance of family, the organization of working time and work-family balance. Patients, continuing education, institutional resources and computer system are the most important attributions for male physician. CONCLUSIONS There are similarities and differences between female and male physicians both in the understanding and the attributions of achievement. The differences are explained by the gender system. The perception of achievement of the female physicians questions the dominant professional culture and incorporates new values in defining achievement. The attributions reflect the unequal impact of family and organizational variables and suggest that the female physicians would be changing gender socialization.

L'hypnose: une ressource en soins palliatifs? Etude qualitative sur l'apport de l'hypnose chez des patients oncologique.s [Hypnosis as a resource in palliative care. A qualitative study of the contribution of hypnosis to the care of oncology patients].

Hypnosis is recognised in medicine as an effective complementary therapy. However, few qualitative data are available concerning the benefits it may bring. This qualitative exploratory study aimed to examine the contribution of hypnosis to the care of advanced cancer patients. Results demonstrate that hypnosis is an effective and efficient means of developing the resources of people suffering from serious illness. After an average of four hypnotherapy sessions, patients said they were able to locate previously unexploited resources within themselves and were able to become autonomous in the use of self-hypnosis. The major benefit reported concerned a reduction in anxiety. For patients experiencing anxiety about death, hypnosis allowed them, within a therapeutic environment perceived as safe, to explore different facets of their fears and to develop adaptive strategies. Aside from slight fatigue experienced during the sessions, no adverse side-effects were reported. In conclusion, this study exploring the effects of hypnosis allowed us to identify important benefits for patients suffering from advanced cancer. Consequently, replication on a larger scale is recommended in order to ascertain the extent to which it is possible to generalise from these results and in order better to define the characteristics of patients most likely to benefit from this therapy.

Performing masculinity, influencing health: a qualitative mixed-methods study of young Spanish men

Background: The literature shows how gender mandates contribute to differences in exposure and vulnerability to certain health risk factors. This paper presents the results of a study developed in the south of Spain, where research aimed at understanding men from a gender perspective is still limited. Objective: The aim of this paper is to explore the lay perceptions and meanings ascribed to the idea of masculinity, identifying ways in which gender displays are related to health. Design: The study is based on a mixed-methods data collection strategy typical of qualitative research. We performed a qualitative content analysis focused on manifest and latent content. Results: Our analysis showed that the relationship between masculinity and health was mainly defined with regard to behavioural explanations with an evident performative meaning. With regard to issues such as driving, the use of recreational drugs, aggressive behaviour, sexuality, and body image, important connections were established between manhood acts and health outcomes. Different ways of understanding and performing the male identity also emerged from the results. The findings revealed the implications of these aspects in the processes of change in the identity codes of men and women. Conclusions: The study provides insights into how the category ‘man’ is highly dependent on collective practices and performative acts. Consideration of how males perform manhood acts might be required in guidance on the development of programmes and policies aimed at addressing gender inequalities in health in a particular local context.

Estimating Gross Value Added (GVA) across multiple scales: theoretical approach and empirical validation

This paper presents an application of the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) approach to the estimation of quantities of Gross Value Added (GVA) referring to economic entities defined at different scales of study. The method first estimates benchmark values of the pace of GVA generation per hour of labour across economic sectors. These values are estimated as intensive variables –e.g. €/hour– by dividing the various sectorial GVA of the country (expressed in € per year) by the hours of paid work in that same sector per year. This assessment is obtained using data referring to national statistics (top down information referring to the national level). Then, the approach uses bottom-up information (the number of hours of paid work in the various economic sectors of an economic entity –e.g. a city or a province– operating within the country) to estimate the amount of GVA produced by that entity. This estimate is obtained by multiplying the number of hours of work in each sector in the economic entity by the benchmark value of GVA generation per hour of work of that particular sector (national average). This method is applied and tested on two different socio-economic systems: (i) Catalonia (considered level n) and Barcelona (considered level n-1); and (ii) the region of Lima (considered level n) and Lima Metropolitan Area (considered level n-1). In both cases, the GVA per year of the local economic entity –Barcelona and Lima Metropolitan Area – is estimated and the resulting value is compared with GVA data provided by statistical offices. The empirical analysis seems to validate the approach, even though the case of Lima Metropolitan Area indicates a need for additional care when dealing with the estimate of GVA in primary sectors (agriculture and mining).

Experiencias y cambios en los padres de niños con parálisis cerebral infantil: estudio cualitativo.

BACKGROUND The diagnosis of infant cerebral palsy (ICP) is a traumatic event that can provoke multiple effects and changes in the family. The aim of the study is to discover the difficulties that parents face in the process of parenting, especially in the initial period following diagnosis. METHODS A qualitative study was carried out through semi-structured interviews. Sixteen mothers and fathers whose children were diagnosed with cerebral palsy participated in the study. Data analysis was performed with Atlas.ti 6.2 software following a strategy of open coding. RESULTS The reception of the diagnosis is perceived as an unexpected event that makes parents change expectations and hopes related to their children. The mode of relation with the child with ICP is different from that with other children as parents are more focused on the possibility of improvement and the future evolution of their child. Changes in different aspects of the lives of these parents are shown, such as demands on time, their economic and labour situation, as well as the relationship of the couple. CONCLUSIONS In providing care for children with cerebral palsy it is necessary to take the problems of the parents into account, especially in the initial period after diagnosis. The process of parenting a child with cerebral palsy entails many changes in the family so a global perspective is needed to organize interventions.

Tuberculosis in migrant populations. A systematic review of the qualitative literature.

BACKGROUND The re-emergence of tuberculosis (TB) in low-incidence countries and its disproportionate burden on immigrants is a public health concern posing specific social and ethical challenges. This review explores perceptions, knowledge, attitudes and treatment adherence behaviour relating to TB and their social implications as reported in the qualitative literature. METHODS Systematic review in four electronic databases. Findings from thirty selected studies extracted, tabulated, compared and synthesized. FINDINGS TB was attributed to many non-exclusive causes including air-born transmission of bacteria, genetics, malnutrition, excessive work, irresponsible lifestyles, casual contact with infected persons or objects; and exposure to low temperatures, dirt, stress and witchcraft. Perceived as curable but potentially lethal and highly contagious, there was confusion around a condition surrounded by fears. A range of economic, legislative, cultural, social and health system barriers could delay treatment seeking. Fears of deportation and having contacts traced could prevent individuals from seeking medical assistance. Once on treatment, family support and "the personal touch" of health providers emerged as key factors facilitating adherence. The concept of latent infection was difficult to comprehend and while TB screening was often seen as a socially responsible act, it could be perceived as discriminatory. Immigration and the infectiousness of TB mutually reinforced each another exacerbating stigma. This was further aggravated by indirect costs such as losing a job, being evicted by a landlord or not being able to attend school. CONCLUSIONS Understanding immigrants' views of TB and the obstacles that they face when accessing the health system and adhering to a treatment programme-taking into consideration their previous experiences at countries of origin as well as the social, economic and legislative context in which they live at host countries- has an important role and should be considered in the design, evaluation and adaptation of programmes.

Advance directives and the impact of timing. A qualitative study with Swiss general practitioners.

PRINCIPLES: Advance directives are seen as an important tool for documenting the wishes of patients who are no longer competent to make decisions in regards to their medical care. Due to their nature, approaching the subject of advance directives with a patient can be difficult for both the medical care provider and the patient. This paper focuses on general practitioners' perspectives regarding the timing at which this discussion should take place, as well as the advantages and disadvantages of the different moments. METHODS: In 2013, 23 semi-structured face-to-face interviews were performed with Swiss general practitioners. Interviews were analysed using qualitative content analysis. RESULTS: In our sample, 23 general practitioners provided different options that they felt were appropriate moments: either (a) when the patient is still healthy, (b) when illness becomes predominant, or (c) when a patient has been transferred to a long-term care facility. Furthermore, general practitioners reported uncertainty and discomfort regarding initiating the discussion. CONCLUSION: The distinct approaches, perspectives and rationales show that there is no well-defined or "right" moment. However, participants often associated advance directives with death. This link caused discomfort and uncertainty, which led to hesitation and delay on the part of general practitioners. Therefore we recommend further training on how to professionally initiate a conversation about advance directives. Furthermore, based on our results and experience, we recommend an early approach with healthy patients paired with later regular updates as it seems to be the most effective way to inform patients about their end-of-life care options.

The European Union in North Korea: Current Realities and Paths for Future Engagement – A Qualitative and Quantitative Study

Malgrat la rellevància estratègica i el paper desestabilitzador de Corea del Nord a la regió econòmicament més dinàmica del món, la UE no compta amb cap estratègia clara per involucrar-se amb aquest país. Combinant tècniques d’anàlisi qualitatives i quantitatives, aquest treball pretén descobrir possibles contradiccions internes que impedeixin la definició d'una política exterior europea coherent i efectiva amb respecte a Corea del Nord, així com discrepàncies entre les percepcions d’actors interns de la UE i les d’actors externs. S'han detectat importants diferències d’expectatives i mancances en termes de coherència, tant entre les visions expressades pels actors interns com entre les opinions d’aquests actors i les dels futurs líders sudcoreans enquestats – diferències que fins i tot afecten la promoció dels drets humans

Empirical approaches to inequality of opportunity: principles, measures, and evidence

We put together the different conceptual issues involved in measuring inequality of opportunity, discuss how these concepts have been translated into computable measures, and point out the problems and choices researchers face when implementing these measures. Our analysis identifies and suggests several new possibilities to measure inequality of opportunity. The approaches are illustrated with a selective survey of the empirical literature on income inequality of opportunity.

Diez aportaciones del empleo de la metodología cualitativa en una auditoría de comunicación interna en Atención Primaria.

Qualitative methodology, originally belonging to the Social Sciences domain, has progressively incorporated to Health Research to the scepticism of many and the admiration of others. Nowadays, validity and fiability of these qualitative techniques is still questioned by a great amount of health researchers and their use provokes doubt among reviewers and other members of the scientific community. This article presents as a fundamental measure for the validity of the qualitative methodology its precise use to approach determinate research objectives specific to them and, echoing the extra issue of the Health Services Research on December 1999 on this methodology, gathers the contribution of the use of these techniques from a complementary point of view, in a Internal Communication Audit conducted in the Primary Care Services of four Regional Health Systems: Area II of the INSALUD (National Health Institute), Basque Health System, Canary Health System and Andalusian Health System.

Impact of inadequate empirical therapy on the mortality of patients with bloodstream infections: a propensity score-based analysis.

The impact of the adequacy of empirical therapy on outcome for patients with bloodstream infections (BSI) is key for determining whether adequate empirical coverage should be prioritized over other, more conservative approaches. Recent systematic reviews outlined the need for new studies in the field, using improved methodologies. We assessed the impact of inadequate empirical treatment on the mortality of patients with BSI in the present-day context, incorporating recent methodological recommendations. A prospective multicenter cohort including all BSI episodes in adult patients was performed in 15 hospitals in Andalucía, Spain, over a 2-month period in 2006 to 2007. The main outcome variables were 14- and 30-day mortality. Adjusted analyses were performed by multivariate analysis and propensity score-based matching. Eight hundred one episodes were included. Inadequate empirical therapy was administered in 199 (24.8%) episodes; mortality at days 14 and 30 was 18.55% and 22.6%, respectively. After controlling for age, Charlson index, Pitt score, neutropenia, source, etiology, and presentation with severe sepsis or shock, inadequate empirical treatment was associated with increased mortality at days 14 and 30 (odds ratios [ORs], 2.12 and 1.56; 95% confidence intervals [95% CI], 1.34 to 3.34 and 1.01 to 2.40, respectively). The adjusted ORs after a propensity score-based matched analysis were 3.03 and 1.70 (95% CI, 1.60 to 5.74 and 0.98 to 2.98, respectively). In conclusion, inadequate empirical therapy is independently associated with increased mortality in patients with BSI. Programs to improve the quality of empirical therapy in patients with suspicion of BSI and optimization of definitive therapy should be implemented.
