Condiciones de trabajo y salud en trabajadores del área administrativa y asistencial de una IPS en ciudad de Bogotá

Habitualmente el personal administrativo y asistencial está sometido a diferentes riesgos en su condición laboral, ya sea por factores físicos o psicológicos. Por lo general, estos riesgos se asocian a personas o a condiciones del ambiente que pueden llegar a afectar la realización de la labor del trabajador, pero además, su diversidad de cargas relacionadas con factores intralaborales hacen que se generen diferentes clases de alteraciones mentales (como el estrés) y físicas, que pueden desencadenar insatisfacción laboral para realizar sus actividades laborales. Objetivo: Determinar las condiciones de trabajo y salud en trabajadores del área administrativa y asistencial de una IPS en ciudad de Bogotá Metodología: Estudio de corte transversal, con una muestra de 92 trabajadores, del área administrativa y asistencial de una IPS en la ciudad de Bogotá. Se recolecto la información por medio del Cuestionario Condiciones de Trabajo y Salud adaptado, a partir de la VI Encuesta Nacional de Condiciones de Trabajo del Instituto Nacional de Seguridad e Higiene en el Trabajo de España (INSHT) del 2007 y el Cuestionario General de Salud de Goldberg (GHQ-12). Se uso el método descriptivo con medidas de tendencia central y dispersión para las variables cuantitavitas y frecuencias, junto con porcentajes para las variables cualitativas. Resultados: En esta investigación participaron 92 trabajadores, de los cuales el 73% fueron mujeres mientras el 27% eran hombres. El 27.2% de los trabajadores presentaron dolor de espalda lumbrosacra y el 29.4% cervical. El dolor de cabeza fue referido por el 74%, los problemas visuales por el 45.7% y los auditivos por el 45.7%. El 31% de los trabajadores tienen una percepción de seguridad en su trabajo alta. Conclusiones: Los trabajadores asistenciales y administrativos presentaron problemas musculoesqueleticos, además, tienen un ritmo de trabajo acelerado y están expuestos a ruido en el lugar de trabajo. Por lo anterior, es importante realizar seguimiento en los puestos de trabajo, desarrollar actividades de promoción y prevención, programas de vigilancia epidemiológica, al igual que incentivar las pausas activas dentro de la empresa.

Terapia chirurgica dell'acalasia scompensata: prevalenza e fattori di rischio per lo sviluppo del carcinoma esofageo, risultati clinico-funzionali a lungo termine della chirurgia conservativa e dell'esofagectomia

La chirurgia conservativa o l’esofagectomia, possono essere indicate per il trattamento della disfagia nell’acalasia scompensata. L’esofagectomia è inoltre finalizzata alla prevenzione dello sviluppo del carcinoma esofageo. Gli obiettivi erano: a) definire prevalenza e fattori di rischio per il carcinoma epidermoidale; b) confrontare i risultati clinici e funzionali di Heller-Dor con pull-down della giunzione esofagogastrica (PD-HD) ed esofagectomia. I dati in analisi, ricavati da un database istituito nel 1973 e finalizzato alla ricerca prospettica, sono stati: a) le caratteristiche cliniche, radiologiche ed endoscopiche di 573 pazienti acalasici; b) il risultato oggettivo e la qualità della vita, definita mediante questionario SF-36, dopo intervento di PD-HD (29 pazienti) e dopo esofagectomia per acalasia scompensata o carcinoma (20 pazienti). Risultati: a) sono stati diagnosticati 17 carcinomi epidermoidali ed un carcinosarcoma (3.14%). Fattori di rischio sono risultati essere: il diametro esofageo (p<0.001), il ristagno esofageo (p<0.01) e la durata dei sintomi dell’acalasia (p<0.01). Secondo l’albero di classificazione, soltanto i pazienti con esito insufficiente del trattamento ai controlli clinico-strumentali ed acalasia sigmoidea presentavano un rischio di sviluppare il carcinoma squamocellulare del 52.9%. b) Non sono state riscontrate differenze statisticamente significative tra i pazienti sottoposti ad intervento conservativo e quelli trattati con esofagectomia per quanto concerne l’esito dell’intervento valutato mediante parametri oggettivi (p=0.515). L’analisi della qualità della vita non ha evidenziato differenze statisticamente significative per quanto concerne i domini GH, RP, PF e BP. Punteggi significativamente più elevati nei domini RE (p=0.012), VT (p<0.001), MH (p=0.001) e SF (p=0.014) sono stati calcolati per PD-HD rispetto alle esofagectomie. In conclusione, PD-HD determina una miglior qualità della vita, ed è pertanto la procedura di scelta per i pazienti con basso rischio di cancro. A coloro che abbiano già raggiunto i parametri di rischio, si offrirà l’esofagectomia o l'opzione conservativa seguita da protocolli di follow-up.

Methylmercury and polycyclic aromatic hydrocarbons in Mediterranean seafood: a molecular anthropological perspective

Seafood carries several contaminants, among which mercury and polycyclic aromatic hydrocarbons are those that cause major concern. Evidence exists that human populations are exposed to these environmental chemicals since ancient times, which may have driven the positive selection of specific genetic polymorphisms related to chemicals toxicokinetic. Both mercury and polycyclic aromatic hydrocarbons are able to cause DNA methylation changes in humans. Some Mediterranean populations may be particularly exposed to these contaminants, being the Mediterranean Sea at a high-risk for contamination by toxic compounds, and because of their traditionally high consumption of locally caught seafood. Starting from these premises the present thesis aims to contribute to the understanding of the molecular impact of seafood consumption on the biology of the Mediterranean population. To this end the work has been divided into four main parts: (1) the development and meta-analysis of a georeferenced database on polycyclic aromatic hydrocarbons in Mediterranean seafood aimed at identifying geographical patterns of contamination and trends that could be related to the biology of the marine organisms, to the physico-chemical properties of each hydrocarbon and to the oceanographic characteristic of the Mediterranean; (2) the development and validation of a food frequency questionnaire to estimate the intake of mercury through seafood consumption among a population living in a geographic area that is usually considered a contamination hotspot; (3) the creation of a biobank made of biological samples from members of several Italian communities together with information on their dietary habits, lifestyle and general health; (4) a review of the literature on the genetic component of individual susceptibility to methylmercury and polycyclic aromatic hydrocarbons exposure in humans, to the effects that these pollutants have on human DNA methylation, and to the evidence that Mediterranean coastal communities represent an informative case study to investigate the potential molecular impact of these chemicals.

Assessing perceived need for mental health care in a community survey: development of the Perceived Need for Care Questionnaire (PNCQ)

Background: The Perceived Need for Care Questionnaire (PNCQ) was designed for the Australian National Survey of Mental Health and Wellbeing. The PNCQ complemented collection of data on diagnosis and disability with the survey participants' perceptions of their needs for mental health care and the meeting of those needs. The four-stage design of the PNCQ mimics a conversational exploration of the topic of perceived needs. Five categories of perceived need are each assigned to one of four levels of perceived need (no need, unmet need, partially met need and met need). For unmet need and partially met need, information on barriers to care is collected, Methods: Inter-rater reliabilities of perceived needs assessed by the PNCQ were examined in a study of 145 anxiety clinic attenders. Construct validity of these items was tested, using a multi-trait multi-method approach and hypotheses regarding extreme groups, in a study with a sample of 51 general practice and community psychiatric service patients. Results: The instrument is brief to administer and has proved feasible for use in various settings. Inter-rater reliabilities for major categories, measured by the kappa statistic, exceeded 0.60 in most cases; for the summary category of all perceived needs, inter-rater reliability was 0.62. The multi-trait multi-method approach lent support to the construct validity of the instrument, as did findings in extreme groups. Conclusions: The PNCQ shows acceptable feasibility, reliability and validity, adding to the range of assessment tools available for epidemiological and health services research.

General scales of community reaction to noise (dissatisfaction and perceived affectedness) are more reliable than scales of annoyance

General measures of reaction to noise, which assess the respondent's perceived affectedness or dissatisfaction, appear to be more valid and internally consistent than more narrow measures, such as specific assessment of noise annoyance. However, the test-retest reliability of general and specific measures has yet to be compared. As a part of the large-scale Sydney Airport Health Study, 97 respondents participated in the same interview twice, several weeks apart. Test-retest reliabilities were found to be significant (p

Perceived need for mental health care: influences of diagnosis, demography and disability

Background. Recent major epidemiological studies have adopted increasingly multidimensional approaches to assessment. Several of these have included some assessment of perceived need for mental health care. The Australian National Survey of Mental Health and Wellbeing, conducted in 1997, included a particularly detailed examination of this construct, with an instrument with demonstrated reliability and validity. Methods. A clustered probability sample of 10641 Australians responded to the field questionnaire for this survey, including questions on perceived need either where there had been service utilization, or where a disorder was detected by administration of sections of the Composite International Diagnostic Interview. The confidentialized unit record file generated from the survey was analysed for determinants of perceived need. Results. Perceived need is increased in females, in people in the middle years of adulthood, and in those who have affective disorders or co-morbidity. Effects of diagnosis and disability can account for most of the differences in gender specific rates. With correction for these effects through regression, there is less perceived need for social interventions and possibly more for counselling in females; disability is confirmed as strongly positively associated with perceived need, as are the presence of affective disorders or co-morbidity. Conclusions. The findings of this study underscore the imperative for mental health services to be attentive and responsive to consumer perceived need. The substantial majority of people who are significantly disabled by mental health problems are among those who see themselves as having such needs.

General practitioners can evaluate the material, social and health dimensions of patient social status

OBJECTIVE: To identify which physician and patient characteristics are associated with physicians' estimation of their patient social status.DESIGN: Cross-sectional ulticentric survey. SETTING: Fourty-seven primary care private offices in Western Switzerland. PARTICIPANTS: Random sample of 2030 patients ≥ 16, who encountered a general practitioner (GP) between September 2010 and February 2011. MAIN MEASURES: PRIMARY OUTCOME: patient social status perceived by GPs, using the MacArthur Scale of Subjective Social Status, ranging from the bottom (0) to the top (10) of the social scale.Secondary outcome: Difference between GP's evaluation and patient's own evaluation of their social status. Potential patient correlates: material and social deprivation using the DiPCare-Q, health status using the EQ-5D, sources of income, and level of education. GP characteristics: opinion regarding patients' deprivation and its influence on health and care. RESULTS: To evaluate patient social status, GPs considered the material, social, and health aspects of deprivation, along with education level, and amount and type of income. GPs declaring a frequent reflexive consideration of their own prejudice towards deprived patients, gave a higher estimation of patients' social status (+1.0, p = 0.002). Choosing a less costly treatment for deprived patients was associated with a lower estimation (-0.7, p = 0.002). GP's evaluation of patient social status was 0.5 point higher than the patient's own estimate (p<0.0001). CONCLUSIONS: GPs can perceive the various dimensions of patient social status, although heterogeneously, according partly to their own characteristics. Compared to patients' own evaluation, GPs overestimate patient social status.

Self reported physical activity, public health, and perceived environment: results from a comparative European study

The focus of physical activity promotion is moving from methods for increasing health enhancing physical activity on the individual level to higher level strategies including environmental and policy approaches. Scientific inquiry, traditionally related to individual-based strategies, requires adaptation and refinement when environmental and policy changes become more relevant. The objective of this study is to investigate the significance for behaviour and health of community-based environments that encourage physical activity. DESIGN AND SETTING The article presents data and results from a cross sectional comparative survey of the general population in six European countries (Belgium, Finland, Germany (East and West), Netherlands, Spain, Switzerland). Specifically, the relation between perceived community-based opportunities for physical activity, self reported physical activity, and self rated health status is investigated. PARTICIPANTS Representative samples of general populations (adults 18 years or older). Overall response rate: 53.5%. Sample sizes realised: Belgium: n=389; Finland: n=400; Germany (East): n = 913; Germany (West): n=489; Netherlands: n=366; Spain: n=380; Switzerland: n=406. MAIN RESULTS Analyses show that best opportunities are reported by people who are lightly to moderately physically active. People's self rated health is moderately, but significantly associated with both perceived opportunities, and physical activity itself. These predictors interact in that especially for women, the health impact of physical activity is more pronounced in case of good opportunities. CONCLUSIONS The paper shows the potential of opportunities within residential and community environments with regard to physical activity, both for behaviour and health. Opportunities may enable the population, especially women, to develop an active lifestyle, and thus improve their health. Future studies with objective indicators for physical activity related environments should test the findings that are based on perceptions.

FAMILY MEDICINE RESIDENT SURVEY ON HEALTH PROMOTION (PERSONAL EXPECTATIONS, BEHAVIORS, PERCEIVED SELF-EFFICACY, COGNITIVE ASSESSMENT, OUTCOME EXPECTANCY)

This study was designed to test the theoretical predictors of personal efficacy expectations among family medicine resident physicians for helping their patients change thirteen high risk health behaviors. A survey questionnaire was sent to 781 family medicine residents in the six state south central region. The response rate was 60 percent. The hypothesized relationship between lower levels of difficulty and higher personal efficacy expectations was supported by the data. Effort was a significant predictor of perceived self efficacy for health behaviors considered less difficult to change. Situational support did not prove to be a significant predictor for many of the health behaviors. Rate and pattern of success were consistent and significant predictors of perceived self efficacy for helping patients change all thirteen of the health behaviors. Modeling of effective methods by faculty was a significant predictor of efficacy expectations for several but not all of the behaviors. Personal modeling was a significant predictor of perceived efficacy for helping patients change behaviors related to alcohol misuse and exercise. The respondents personally modeled positive health behaviors more consistently than their older colleagues or the general population.^ The results of this study lend substantially to the usefulness of the cognitive-behavioral theory of perceived self efficacy and provide a mechanism for assessing the predictors of personal efficacy expectations of family medicine resident physicians. The findings are expected to have direct implications for faculty to institute systematic programs of interventions designed to increase residents' perceptions of efficacy in facilitating more positive health behaviors among their patients. ^

Perceived sexism as a health determinant in Spain

OBJECTIVES: The goals of the present study are to explore the association between perceived sexism and self-perceived health, health-related behaviors, and unmet medical care needs among women in Spain; to analyze whether higher levels of discrimination are associated with higher prevalence of poor health indicators and to examine whether these relationships are modified by country of origin and social class. MATERIALS AND METHODS: The study is based on a cross-sectional design using data from the 2006 Spanish Health Interview Survey. We included women aged 20-64 years (n = 10,927). Six dependent variables were examined: four of health (self-perceived health, mental health, hypertension, and having had an injury during the previous year), one health behavior (smoking), and another related to the use of the health services (unmet need for medical care). Perceived sexism was the main independent variable. Social class and country of origin were considered as effect modifiers. We obtained the prevalence of perceived sexism. Logistic regression models, adjusted for potential confounders, were fitted to study the association between sexism and poor health outcomes. Results: The prevalence of perceived sexism was 3.4%. Perceived sexism showed positive and consistent associations with four poor health outcomes (poor self-perceived health, poor mental health, injuries in the last 12 months, and smoking). The strength of these associations increased with increased scores for perceived sexism, and the patterns were found to be modified by country of origin and social class. CONCLUSION: This study shows a consistent association between perceived sexism and poor health outcomes in a country of southern Europe with a strong patriarchal tradition.

Attitudes and management of alcohol problems in general practice: Descriptive analysis based on findings of a world health organization international collaborative survey

Aims: To determine if general practitioners' (GPs) experience of education on alcohol, support in their working environment for intervening with alcohol problems, and their attitudes have an impact on the number of patients they manage with alcohol problems. Methods: 1300 GPs from nine countries were surveyed with a postal questionnaire as part of a World Health Organization (WHO) collaborative study. Results: GPs who received more education on alcohol (OR = 1.5; 95% CI, 1.3-1.7), who perceived that they were working in a supportive environment (OR = 1.6; 95% CI, 1.4-1.9), who expressed higher role security in working with alcohol problems (OR = 2.0; 95% CI, 1.5-2.5) and who reported greater therapeutic commitment to working with alcohol problems (OR = 1.4: 95% CI, 1.1-1.7) were more likely to manage patients with alcohol-related harm. Conclusion: Both education and support in the working environment need to be provided to enhance the involvement of GPs in the management of alcohol problems.

External health locus of control and general self-efficacy: Moderators of emotional distress among university students

A belief that doctors or family control one's health outcomes (external health locus of control), and a belief in one's own ability to achieve desired outcomes (general self-efficacy), may influence distress experienced in relation to a physical illness. This study examined the interaction between illness severity, external health locus of control and general self-efficacy in relation to distress. Illness severity was defined as acute or chronic illness, with the latter expected to be more stressful. Participants described a serious illness they experienced, and completed self-report scales in relation to it. Results confirmed that chronic illnesses were associated with more distress than acute illnesses across the sample. Hierarchical multiple regression analyses supported the predicted effects on distress of a three-way interaction involving external health locus of control, general self-efficacy and illness severity (acute vs. chronic). Analysis of these results may assist in explaining inconsistencies in previous research, and offer a model for understanding the role of person variables in emotional distress.

Motivations and perceived influences on rural and urban general practitioners when prescribing conventional non-steroidal anti-inflammatory drugs or COX-2 inhibitors

Background and objective: Prescribers in rural and remote locations perceive that there are different influences on their prescribing compared with those experienced by urban prescribers. The aim of this study was to compare the motivations and perceived influences on general practitioners (GPs) when prescribing COX-2 inhibitors rather than conventional non-steroidal anti-inflammatory drugs (NSAIDs) between rural and urban-based GPs in Queensland, Australia. Methods: A questionnaire was administered to two geographically distinct groups of GPs, one urban (n = 67) and one rural (n = 67), investigating the reasons that the GP would prescribe a COX-2 inhibitor rather than a conventional NSAID or vice versa and also focusing on patients requesting a prescription for a COX-2 inhibitor. Results and discussion: A 51% response rate (n = 68) was achieved. The difference between the rural and the urban GPs was that the urban GPs were more likely to perceive that they were influenced to prescribe COX-2 inhibitors by their patients' knowledge of these new (at the time) drugs. GPs in both the rural and urban areas perceived the COX-2 selective inhibitors to be safer than conventional NSAIDs, and that there was little difference in terms of efficacy between the two drug classes. However, GPs from both of the study areas stated that conventional NSAIDs were preferred over COX-2 selective inhibitors, primarily due to their expense, if their patients were not at risk for developing a GI bleed. Conclusion: The motivations and perceived influences to prescribe a COX-2 inhibitor in rural and in urban areas of Queensland, Australia were very similar. Almost all surveyed GPs in rural and urban areas had patients request a prescription, or enquire about the COX-2 inhibitors. Urban GPs were more likely to feel pressured to prescribe a COX-2 inhibitor than their rural counterparts, agreeing with other research which found that patient pressure to prescribe appears to be greater in urban general practice.

Perceived quality of health care in macular disease:A survey of members of the Macular Disease Society

Aim: To investigate the experiences of people with macular disease within the British healthcare system. Method: The Macular Disease Society Questionnaire, a self completion questionnaire designed to survey the experiences of people with macular disease, was sent to 2000 randomly selected members of the Macular Disease Society. The questionnaire incorporated items about people's experiences with health professionals and the information and support provided by them at the time of diagnosis and thereafter. Results: Over 50% thought their consultant eye specialist was not interested in them as a person and 40% were dissatisfied with their diagnostic consultation. 185 people thought their general practitioner (GP) was well informed about macular disease but twice as many people thought their GP was not well informed. About an equal number of people thought their GP was supportive as those who thought their GP was not supportive. A total of 1247 people were told "nothing can be done to help with your macular disease." A number of negative emotional reactions were experienced by those people as a result, with 61% of them reporting feeling anxious or depressed. Of 282 people experiencing visual hallucinations after diagnosis with macular disease, only 20.9% were offered explanations for them. Concluslons: Many people with macular disease have unsatisfactory experiences of the healthcare system. Many of the reasons for dissatisfaction could be resolved by healthcare professionals if they were better informed about macular disease and had a better understanding of and empathy with patients' experiences.
