[Professional and psychological impact of second victims among hospital healthcare professionals]. / Impacto laboral y psicológico de las segundas víctimas entre los profesionales sanitarios hospitalarios.

OBJECTIVE: To analyze the occupational and psychological consequences suffered by healthcare workers who are considered second victims (SV). MATERIAL AND METHODS: Observational, descriptive and cross-sectional study among the healthcare workers of a university hospital. The answers collected in a specifically designed questionnaire about psychological consequences at work and the result of a post-traumatic stress scale, "Impact of Event Scale-Revised (IES-R, spanish version)" were evaluated. The variables between the groups were compared using the Chi square test (or Fisher's exact test) when both were qualitative and with the Student's T (or the Mann-Whitney U test for independent data), when one of them was quantitative. The level of statistical significance was P<.05. RESULTS: 75.5% (148/207) of the participants in the study suffered some adverse event (AE) and, of these, 88.5% (131/148) were considered SV. Physicians had a 2.2 times higher risk of feeling SV than nurses (95% CI: 1.88-2.52). The impact on the patient related to the AE explained why the professionals involved in it felt SV (P=.037). 80.6% (N=104) of the SVs presented post-traumatic stress. Women were 2.4 times more likely to suffer from it (OR: 2.4; 95% CI: 1.5-4.0). Intrusive thoughts in the SV were almost three times more frequent when the damage suffered by the patient was permanent or death (OR: 2.5; 95% CI: 0.2-3.6). CONCLUSIONS: Many healthcare workers, especially physicians, considered themselves to be SV, and many of them suffered from post-traumatic stress. The impact on the patient related to the AE was a risk factor for being SV and for suffering psychological consequences.

3D scaffolds of caprolactone/chitosan/polyvinyl alcohol/hydroxyapatite stabilized by physical bonds seeded with swine dental pulp stem cell for bone tissue engineering.

Bone Regeneration represents a clinical need, related to bone defects such as congenital anomalies, trauma with bone loss, and/or some pathologies such as cysts or tumors This is why a polymeric biomaterial that mimics the osteogenic composition and structure represents a high potential to face this problem. The method of obtaining these materials was first to prepare a stabilized hydrogel by means of physical bonds and then to make use of the lyophilization technique to obtain the 3D porous scaffolds with temperature conditions of -58 °C and pressure of 1 Pa for 16 h. The physicochemical and bioactive properties of the scaffolds were studied. FTIR and TGA results confirm the presence of the initial components in the 3d matrix of the scaffold. The scaffolds exhibited a morphology with pore size and interconnectivity that promote good cell viability. Together, the cell viability and proliferation test, Alamar BlueTM and the differentiation test: alizarin staining, showed the ability of physically stabilized scaffolds to proliferate and differentiate swine dental pulp stem cell (DPSCs) followed by mineralization. Therefore, the Cs-PCL-PVA-HA scaffold stabilized by physical bonds has characteristics that suggest great utility for future complementary in vitro tests and in vivo studies on bone defects. Likewise, this biomaterial was enhanced with the addition of HA, providing a scaffold with osteoconductive properties necessary for good regeneration of bone tissue. Graphical abstract.

Treatment with Hyaluronic Acid and Collagen-Polyvinylpyrrolidone Improves Extracellular Matrix Assembly for Scarring after Tracheal Resection.

Treatment of tracheal stenosis is occasionally performed in combination with wound healing modulators to manipulate new extracellular matrix (ECM) formation and prevent fibrosis. Hyaluronic acid (HA) and collagen-polyvinylpyrrolidone (collagen-PVP) decrease fibrosis in experimental tracheal healing. However, they have not been used clinically as their effect on ECM components, which modify tracheal scarring, has not been described. Objective. To evaluate the effect of the application of HA, collagen-PVP, a mixture of HA and collagen-PVP (HA+collagen-PVP), and mitomycin C on the expression of decorin, matrix metalloproteinase 1 (MMP1), and MMP9, as well as the type of collagen and deposits formed in the scar after resection and end-to-end anastomosis (REEA) of the cervical trachea using an experimental model. Materials and Methods. Thirty dogs underwent REEA of the cervical trachea and were treated with different wound healing modulators: group I (n = 6), control; group II (n = 6), HA; group III (n = 6), collagen-PVP; group IV (n = 6), HA+collagen-PVP; and group V (n = 6), mitomycin C. The dogs were evaluated clinically and endoscopically for 4 weeks. Subsequently, macroscopic and microscopic changes, expression of ECM proteins, and collagen deposition in tracheal scars were analysed. Results. Groups II, III, and IV showed reduced endoscopic, macroscopic, and microscopic inflammation, improved neovascularization, high decorin expression (p < 0.01, analysis of variance (ANOVA)), and moderate expression of MMP1 (p < 0.003, ANOVA) and type I and III collagen (p < 0.05, Kruskal-Wallis). Groups IV and V developed fewer collagen deposits (p < 0.001, ANOVA). Conclusion. Treatment with HA and collagen-PVP improved post-REEA healing by increasing neovascularization, stimulating the expression of decorin, and regulating the expression of MMP1, as well as type I and III collagen and their deposition.

Evidence supporting the best clinical management of patients with multimorbidity and polypharmacy: a systematic guideline review and expert consensus.

The complexity and heterogeneity of patients with multimorbidity and polypharmacy renders traditional disease-oriented guidelines often inadequate and complicates clinical decision making. To address this challenge, guidelines have been developed on multimorbidity or polypharmacy. To systematically analyse their recommendations, we conducted a systematic guideline review using the Ariadne principles for managing multimorbidity as analytical framework. The information synthesis included a multistep consensus process involving 18 multidisciplinary experts from seven countries. We included eight guidelines (four each on multimorbidity and polypharmacy) and extracted about 250 recommendations. The guideline addressed (i) the identification of the target population (risk factors); (ii) the assessment of interacting conditions and treatments: medical history, clinical and psychosocial assessment including physiological status and frailty, reviews of medication and encounters with healthcare providers highlighting informational continuity; (iii) the need to incorporate patient preferences and goal setting: eliciting preferences and expectations, the process of shared decision making in relation to treatment options and the level of involvement of patients and carers; (iv) individualized management: guiding principles on optimization of treatment benefits over possible harms, treatment communication and the information content of medication/care plans; (v) monitoring and follow-up: strategies in care planning, self-management and medication-related aspects, communication with patients including safety instructions and adherence, coordination of care regarding referral and discharge management, medication appropriateness and safety concerns. The spectrum of clinical and self-management issues varied from guiding principles to specific recommendations and tools providing actionable support. The limited availability of reliable risk prediction models, feasible interventions of proven effectiveness and decision aids, and limited consensus on appropriate outcomes of care highlight major research deficits. An integrated approach to both multimorbidity and polypharmacy should be considered in future guidelines.

[A brief history of marijuana in the western world]. / Breve historia sobre la marihuana en Occidente.

Marijuana is a substance with a long and controversial history. At different times in its history, which goes back over 5,000 years, this plant has been used for different purposes, ranging from recreational and leisure to its use in the treatment of several diseases or to offer relief in processes that entail a certain type of malaise, and including its consideration as a means of relaxation and meditation. Although it was supposed that the roots of marijuana lay in Central America, it is now known that this is but an urban legend with little credibility and that its origins can be found recorded in Chinese medical references dating back to the year 2737 BC. Although this plant was not originally from Central America, it has aroused interest around the world, and above all in Mexico. It is in this country where the use of cannabis has gone from applications in textiles and medicine to its free sale, the bans on its use due to political and social pressures, its tolerance and, recently, its decriminalisation for recreational and medicinal use. Unfortunately there are few references on the history of this plant in Mexico, and thus we have considered it interesting to present some data about the generalities of marijuana, a brief history in the world, the development of decriminalisation in North America, its medicinal uses and its course through Mexico to the present day.

TITLE: Breve historia sobre la marihuana en Occidente.La marihuana es una sustancia con una extensa y controvertida historia. A lo largo del tiempo, esta planta, y desde hace mas de 5.000 años, ha sido utilizada para diferentes fines, que van desde el uso ludico y recreativo, pasando por un medio de relajacion y meditacion, hasta su uso en el tratamiento de varias enfermedades o el alivio de procesos vinculados a cierto tipo de malestares. Aunque se supuso que la marihuana tenia su origen en Mesoamerica, ahora se sabe que es solo una leyenda urbana de poca credibilidad y que sus origenes los podemos registrar en referencias medicas chinas datadas alrededor del año 2737 a. de C. Si bien esta planta no tiene un origen mesoamericano, si ha generado interes en el mundo, y sobre todo en Mexico. Es en este pais donde el uso del cannabis ha ido desde intereses textiles y medicinales hasta el consumo ludico, pasando por su venta libre, la prohibicion por presiones politicas y sociales, su tolerancia y, recientemente, su despenalizacion para uso ludico y medicinal. Desgraciadamente existen pocas referencias de la historia de esta planta en Mexico, por lo que ha sido de nuestro interes presentar algunos datos sobre las generalidades de la marihuana, una breve historia en el mundo, el desarrollo de la despenalizacion en Norteamerica, sus usos medicinales y su paso por Mexico hasta nuestros dias.

[Suitability of screening for diabetes mellitus in women with a history of gestational diabetes]. / Adecuación del cribado de diabetes mellitus en mujeres con antecedente de diabetes gestacional.

OBJECTIVE: To assess long-term suitability of screening for type 2 diabetes mellitus in women with a previous diagnosis of gestational diabetes in Primary Care. The secondary objectives were to determine if there were clinical factors that modified the usefulness of the screening. MATERIAL AND METHODS: An observational cohort type study was performed, which included all patients with the diagnosis of gestational diabetes during the years 2000 to 2009 (n=470) in the University Hospital Complex of Ourense. The electronic medical records were reviewed to assess the existence of gestational diabetes and the year of the last fasting blood glucose. The mean follow-up time was 12.9 years. The screening for evidence of a fasting blood glucose in the last 3 years was considered adequate. The following variables were analysed: adequacy of screening for type 2 diabetes mellitus, age, body mass index, gestational diabetes in more than one gestation, and rural/urban environment. A descriptive analysis of the data was performed, using Chi2 and Student's t-test to determine differences between subgroups. Statistical significance was considered as P<.05 RESULTS: The long-term monitoring of these patients was very irregular. Only 67.08% of the study group underwent diabetes mellitus type 2 screening. The level of follow-up was not associated with age, BMI, the place of residence, or the year of diagnosis. In patients with more than one episode of gestational diabetes, subsequent blood glucose control was achieved in 94.1%. CONCLUSION: The adequacy of the screening in our area is very irregular and highly improvable.

[Incidence and clinical risk factors for the development of diabetes mellitus in women with previous gestational diabetes]. / Incidencia y factores clínicos de riesgo de diabetes mellitus en mujeres con diabetes gestacional previa.

BACKGROUND: Gestational diabetes is considered a variant of diabetes mellitus as they share a common pathophysiological basis: insulin resistance in target and insufficient secretion of it by pancreatic p-cell bodies. Pregnancy is a unique physiological situation provides an opportunity to identify future risk of diabetes mellitus. OBJECTIVE: To determine the long-term incidence of diabetes mellitus in women who have previously been diagnosed with gestational diabetes and identifying clinical risk factors for developing the same. METHODS: nested case-control cohort study. 671 patients between 1996 and 2009 were diagnosed with gestational diabetes were selected. The incidence of diabetes mellitus was estimated and 2 subgroups were formed: Group A or cases: women who develop diabetes mellitus after diagnosis of gestational diabetes. Group B or control: random sample of 71 women with a history of gestational diabetes in the follow-up period remained normoglycemic. Both groups were studied up to 18 years postpartum. By studying Kaplan Meier survival of the influence of different gestational variables it was obtained in the later development of diabetes mellitus with time parameter and COX models for categorical variables were applied. Significant variables were studied by multivariate Cox analysis. In all analyzes the Hazard ratio was calculated with confidence intervals at 95%. RESULTS: The incidence of diabetes mellitus was 10.3% in patients with a history of gestational diabetes. They were identified as risk factors in the index pregnancy to later development of diabetes mellitus: greater than 35 and younger than 27 years maternal age, BMI greater than 30 kg/m2, hypertensive disorders of pregnancy, insulin therapy, poor metabolic control and more than a complicated pregnancy with gestational diabetes. CONCLUSIONS: Clinical factors have been identified in the pregnancy complicated by gestational diabetes that determine a higher probability of progression to diabetes mellitus in the medium and long term.

[Food habits of the school population from La Mancha-Centro Health Area (Ciudad Real)]. / Patrón dietético de la población escolar del Área La Mancha-Centro (Ciudad Real).

OBJECTIVE: To assess the dietary pattern of the school population from La Mancha-Centro Health Area (Ciudad Real). METHODOLOGY: A cross-sectional study conducted on a representative sample of schoolchildren aged 6 to 12 years, using a questionnaire to determine their general dietary habits and a record of their 24-hour intake. RESULTS: A total of 1142 schoolchildren were included, with 612 boys (53.6%) and 530 girls (46.4%), and a mean age of 9.3 ± 1.7 years of age. The frequency of food intake was 4.62 ± 0.6 times a day, which decreased with the age of the schoolchildren (P=.044), and increased with the educational level of parents (P=.004). Food preference influenced the choice in the meals consumed. The level of appetite was related directly with weight and body mass index (BMI) (P<.001), age (P=.02), and number of daily food intakes by the children (P=.038). The food groups most frequently consumed were cereals and their derivatives (92.8%), milk and dairy products (90.45%), while vegetables were the least consumed (35.46%). Over 70% of the sample usually consumed olive oil. CONCLUSION: The dietary pattern of the school population maintains some of the features of traditional Mediterranean dietary pattern, such as the habit of daily breakfast, the greater consumption of olive oil and cereals. On the other hand, other characteristics are remarkable, such as the low consumption of fruit and vegetables and the high consumption of meat.

Energy-environmental benefits and economic feasibility of anaerobic codigestion of Iberian pig slaughterhouse and tomato industry wastes in Extremadura (Spain).

Anaerobic digestion of Iberian pig slaughterhouse and tomato industry wastes, as well as codigestion operations from such residues, are reported to achieve 54-80% reduction in Chemical Oxygen Demand and 6-19 N m(3)/m(3) substrate methane production. Furthermore, 0.79-0.88 m(3)water/m(3) substrate is seen to be recovered after the above mentioned operations, which might be used as irrigation water, and 0.12-0.21 m(3)agricultural amendment/m(3) substrate with 91-98% moisture content. The present paper also reports on the economic feasibility of both an anaerobic codigestion plant operating with 60% slaughterhouse wastes/40% tomato industry wastes (optimal ratio obtained in previous laboratory-scaled experiments), and an anaerobic digestion plant for Iberian pig slaughterhouse waste. Payback times are reported as 14.86 and 3.73 years, respectively.

Postcoalescence evolution of growth stress in polycrystalline films.

The growth stress generated once grains coalesce in Volmer-Weber-type thin films is investigated by time-multiscale simulations comprising complementary modules of (i) finite-element modeling to address the interactions between grains happening at atomic vibration time scales (~0.1 ps), (ii) dynamic scaling to account for the surface stress relaxation via morphology changes at surface diffusion time scales (~µs-ms), and (iii) the mesoscopic rate equation approach to simulate the bulk stress relaxation at deposition time scales (~sec-h). On the basis of addressing the main experimental evidence reported so far on the topic dealt with, the simulation results provide key findings concerning the interplay between anisotropic grain interactions at complementary space scales, deposition conditions (such as flux and mobility), and mechanisms of stress accommodation-relaxation, which underlies the origin, nature and spatial distribution, and the flux dependence of the postcoalescence growth stress.

[Interobserver agreement in detecting goitre by palpation in a school population]. / Concordancia interobservador en la detección de bocio por palpación en población escolar.

OBJECTIVE: To estimate the agreement between observers on the detection of goitre by physical exploration in a school population. METHODOLOGY: We performed a cross-sectional study to detect goitre in a representative sample of 1134 schoolchildren aged 6 to 12 years from 20 schools in the health area of La Mancha Centro. The examination was performed blinded by two observers. Five grades in thyroid size were established (0, Ia, Ib, II and III). Above grade Ia was considered as goitre. The agreement was assessed in relation to variables such as age, sex, body mass index, height, and day of examination. The weighted kappa was used to measure the agreement. RESULTS: In the 1097 schoolchildren with a dual examination, 96 (8.8%) cases of goitre were detected by observer 1, and 102 (9.3%) cases by observer 2, (P=.58). The degree of interobserver agreement in the identification and grading of goitre was moderate (kappa 0,55, 95%CI: 0,46 to 0,64) for the first, and substantial (weighted kappa 0,61; 95%CI: 0,51 to 0,71) for the second. The degree of agreement was somewhat higher in girls, older schoolchildren, increased weight, height, and body mass index. The interobserver agreement was relatively stable throughout the study. CONCLUSIONS: The interobserver agreement in detecting goitre by palpation in our study is moderate, but is lower in younger children and stable for the duration of study.

An Hcp100 gene fragment reveals Histoplasma capsulatum presence in lungs of Tadarida brasiliensis migratory bats.

Histoplasma capsulatum was sampled in lungs from 87 migratory Tadarida brasiliensis bats captured in Mexico (n=66) and Argentina (n=21). The fungus was screened by nested-PCR using a sensitive and specific Hcp100 gene fragment. This molecular marker was detected in 81·6% [95% confidence interval (CI) 73·4-89·7] of all bats, representing 71 amplified bat lung DNA samples. Data showed a T. brasiliensis infection rate of 78·8% (95% CI 68·9-88·7) in bats captured in Mexico and of 90·4% (95% CI 75·2-100) in those captured in Argentina. Similarity with the H. capsulatum sequence of a reference strain (G-217B) was observed in 71 Hcp100 sequences, which supports the fungal findings. Based on the neighbour-joining and maximum parsimony Hcp100 sequence analyses, a high level of similarity was found in most Mexican and all Argentinean bat lung samples. Despite the fact that 81·6% of the infections were molecularly evidenced, only three H. capsulatum isolates were cultured from all samples tested, suggesting a low fungal burden in lung tissues that did not favour fungal isolation. This study also highlighted the importance of using different tools for the understanding of histoplasmosis epidemiology, since it supports the presence of H. capsulatum in T. brasiliensis migratory bats from Mexico and Argentina, thus contributing new evidence to the knowledge of the environmental distribution of this fungus in the Americas.

New guidelines for the management of thyroid nodules and differentiated thyroid cancer.

AIM: The aim of this paper was to evaluate the diagnostic efficiency of cytology results obtained through fine-needle aspiration (FNA) in partially cystic thyroid nodules and to examine the association between specific ultrasonographic evidence and malignancy. METHODS: A descriptive, observational, cross-sectional study examining the relationship between cytological and ultrasonographic findings in a group of patients with partially cystic thyroid nodules. The following ultrasound characteristics were examined: 1) nodule size (in mm); 2) percentage of the solid portion of the nodule (greater or less than 50%); 3) echogenicity of the solid portion (hypoechoic, isoechoic, or hyperechoic); 4) eccentricity of the solid portion; 5) regularity of the margins, and 6) presence or absence of microcalcifications. RESULTS: The ultrasound (US) and cytological characteristics of the partially cystic thyroid nodules of 145 patients, 127 women with a mean age of 53.1 years (SD 19.7) and 18 men with a mean age of 60 (SD 19.7), were reviewed. The mean size of the nodules was 28.07 mm (SD 11.23). Thirty-seven (25.5%) were solitary nodules and 98 (72.59%) formed parts of multinodular goiters. Twenty-eight (19.3%) of the cytologies proved to be inadequate samples, 104 (71.7%) were benign, 7 (4.8%) were suspicious, and 4 (2.8%) were malignant. The sensitivity for detecting malignancy was >90% when the percentage of the solid portion of the nodule was greater than 50%; these values remained unchanged when combined with other sonographic findings. The greatest specificity for malignancy was associated with the presence of microcalcifications (99%); however, none of the associations observed were statistically significant. CONCLUSION: FNA cytology is an essential diagnostic tool in both partially cystic and solid nodules. Examination of several individual ultrasound characteristics of these nodules, such as the percentage of the solid component, as well as other common characteristics, including the echogenicity or the presence of microcalcifications, may greatly facilitate the diagnostic process.

Morphology Analysis of Si Island Arrays on Si(001).

The formation of nanometer-scale islands is an important issue for bottom-up-based schemes in novel electronic, optoelectronic and magnetoelectronic devices technology. In this work, we present a detailed atomic force microscopy analysis of Si island arrays grown by molecular beam epitaxy. Recent reports have shown that self-assembled distributions of fourfold pyramid-like islands develop in 5-nm thick Si layers grown at substrate temperatures of 650 and 750°C on HF-prepared Si(001) substrates. Looking for wielding control and understanding the phenomena involved in this surface nanostructuring, we develop and apply a formalism that allows for processing large area AFM topographic images in a shot, obtaining surface orientation maps with specific information on facets population. The procedure reveals some noticeable features of these Si island arrays, e.g. a clear anisotropy of the in-plane local slope distributions. Total island volume analysis also indicates mass transport from the substrate surface to the 3D islands, a process presumably related to the presence of trenches around some of the pyramids. Results are discussed within the framework of similar island arrays in homoepitaxial and heteroepitaxial semiconductor systems.

[Brain natriuretic peptide in primary care: diagnostic value in heart failure]. / Péptido cerebral natriurético en atención primaria: valor diagnóstico en la insuficiencia cardíaca.

OBJECTIVE: To determine the validity and usefulness of brain natriuretic peptide (BNP) for diagnosing left ventricular dysfunction (LVD). DESIGN: Prospective, descriptive, multi-centred study to validate the diagnostic test. SETTING: Primary care centres in the Community of Madrid, Spain. PARTICIPANTS: Consecutive sample of patients at high risk of presenting with LVD. INTERVENTIONS: Data will be gathered from anamnesis, physical examination, ECG, and chest x-ray to find the risk factor(s) for LVD and the presence or absence of symptoms of congestive heart failure according to the Framingham scale. BNP will be determined at PC clinics in all patients who meet the inclusion criteria, using the "triage BNP test." All patients included in the study will be referred to an echocardiography service for an echocardiogram, which will be the gold standard test. Two independent cardiologists will evaluate the echocardiograph without knowing the BNP values. MAIN MEASUREMENTS: BNP concentrations will be compared against the kind and degree of LVD. ROC curves analysis will test the capacity of BNP to diagnose LVD. Optimal sensitivity and specificity value will be calculated by means of the position on the curve resulting from the minimum distance at the cut-off point for best sensitivity and specificity. Then, sensitivity, specificity, and positive and negative predictive values will be calculated. DISCUSSION: BNP can complement the information provided by other diagnostic tests. It should be included as an important factor in the taking of clinical-therapeutic decisions.

[Primary care doctors needs for information: analysis of questions and how they were answered]. / Necesidades de información de los médicos de atención primaria: análisis de preguntas y su resolución.

OBJECTIVE: To assess what information primary care doctors from 5 health areas of Madrid need, through the description of the frequency and kind of clinical questions that arise, the pattern of search for the answers and how well they were answered. DESIGN: Descriptive, observational study. Setting. Primary care consultations in health areas 1, 3, 8, 9, and 10, Madrid, Spain. PARTICIPANTS: Randomised sample, stratified by zone, and kind of doctor, of 125 doctors from each area (Madrid). Residents, locums, and university teachers were excluded. INTERVENTIONS: Doctors will be invited to be observed by video camera for about four hours of on-demand consultation. They will be asked between patients to specify the questions that arise and the sources of information used in the consultation. Unresolved questions will be followed up by means of phone contact 2 weeks later, to see whether they had found answers and what methods they used to find them. MAIN VARIABLES: number of recognised clinical questions formulated and their answers; number of clinical questions not recognised (as observed by video); each question's theme and kind of information; time used to look for answers; information resources used. Other variables: characteristics of the PC professionals taking part, consultations, health centres, and case-loads. DISCUSSION: Restrictions: Hawthorne effect or bias in the person observed and participants stage fright. Applicability: the results of the research will be used to plan the resources needed for doctors to enjoy and put into practice the best scientific knowledge.

[Systematic review of group educational interventions in type-2 diabetes patients]. / Revisión sistemática de las intervenciones educativas grupales en pacientes diabéticos tipo 2.

OBJECTIVES: To evaluate the effect of group educational interventions in type-2 diabetes patients. To analyse what kind of group intervention has the best long-term effects. DESIGN: Systematic review. DATA SOURCES: Review of electronic data bases: CENTRAL, MEDLINE, EMBASE, CINAHL, and PASCAL, and of the bibliographic references of the studies selected. Contacts with experts to locate non-published articles. Selection of studies. Randomised clinical studies with controls and quasi-experimental studies that evaluate group education interventions aimed at type-2 diabetes patients over 18 years old. These interventions were of any length and in any context, and their target was to improve quality of life, self-control, or metabolic control. The comparison group included individual educational interventions and non-interventions. VARIABLES RESULT: Quality of life, self-control, and diabetes control (HbA1c, cholesterol, triglycerides, blood pressure, and smoking). REVIEW METHODS: Trial selection by 3 groups with 3 researchers in each, who independently reviewed headings, abstracts and key words of all the identified trials to decide on their eligibility. The quality of trials was evaluated by the criteria defined by the Cochrane Metabolic and Endocrine Disorders Group. Researchers assessed the articles independently; and discrepancies were resolved by discussion and consensus.

[Effectiveness of non-pharmacological primary care methods for giving up tobacco dependency]. / Efectividad de los métodos no farmacológicos para la deshabituación tabáquica en atención primaria.

OBJECTIVE: To determine the effectiveness of a systematic and intensive programme of tobacco counselling, as against brief anti-tobacco counselling. DESIGN: Controlled and randomised clinical trial. SETTING: Primary care medical and nursing clinics at an urban Health Centre in Getafe. PARTICIPANTS: Smokers who request health care at the medical clinics for any reason during the recruitment period, who satisfy the inclusion criteria and who want to take part in the study. The inclusion criteria are: 18 years old or more, people who have smoked daily during the previous month any amount of cigarettes, and high motivation (score over 7 on the Richmond test). INTERVENTION: The 110 patients recruited by each doctor will be included, depending on the clinic they come from, in the control group (brief counselling) or the intervention group (intensive counselling). For the patients in the intervention group, monitoring visits will be programmed for 6 months after giving up. Both groups will be called by phone after a year to see if they are still smoking. MAIN MEASUREMENTS: Abstinence at 12 months. SECONDARY MEASUREMENTS: a) Recorded at the start: personal details, medical history and smoking history; b) recorded at the consultations: abstinence, date of first giving up and symptoms of withdrawal syndrome. DISCUSSION: The study will define the role of nursing professionals in taking patients off tobacco and will help define the effectiveness of non-medical methods to achieve this.
