A multicentric study regarding the use of hormone therapy during female mid-age (REDLINC VI).

BACKGROUND: Menopausal hormone therapy (HT) has shown benefits for women; however, associated drawbacks (i.e. risks, costs, fears) have currently determined its low use. OBJECTIVE: To determine the prevalence of current HT use among mid-aged women and describe the characteristics of those who have never used, have abandoned or are currently using HT. In addition, reasons for not using HT were analyzed. METHOD: This was a cross-sectional study that analyzed a total of 6731 otherwise healthy women (45-59 years old) of 15 cities in 11 Latin American countries. Participants were requested to fill out the Menopause Rating Scale (MRS) and a questionnaire containing sociodemographic data and items regarding the menopause and HT use. RESULTS: The prevalence of current HT use was 12.5%. Oral HT (43.7%) was the most frequently used type of HT, followed by transdermal types (17.7%). The main factors related to the current use of HT included: positive perceptions regarding HT (odds ratio (OR) 11.53, 95% confidence interval (CI) 9.41-14.13), being postmenopausal (OR 3.47, 95% CI 2.75-4.36) and having a better socioeconomic level. A total of 48.8% of surveyed women had used HT in the past, but abandoned it due to symptom improvement or being unconcerned; fear of cancer or any other secondary effects were also reported but in less than 10%. Among women who had never used HT, 28% reported the lack of medical prescription as the main reason, followed by the absence of symptoms (27.8%). Among those reporting lack of prescription as the main reason for not using HT, 30.6% currently had severe menopausal symptoms (total MRS score > 16); 19.5% of women were using alternative 'natural' therapies, with 35.1% of them displaying severe menopausal symptoms as compared to a 22.5% observed among current HT users. CONCLUSION: The use of HT has not regained the rates observed a decade ago. Positive perceptions regarding HT were related to a higher use. Lack of medical prescription was the main reason for not using HT among non-users, many of whom were currently displaying severe menopausal symptoms.

[Prevalence of childhood obesity in the Murcia Region; an assessment of different references for body mass index]. / Prevalencia de obesidad infantil en la Región de Murcia, valorando distintas referencias para el índice de masa corporal.

INTRODUCTION: Childhood obesity is a problem of high magnitude with serious repercussions on health, which justifies estimating its prevalence at local level to identify conditioning factors and to take preventive actions. The main objective of the present work is to estimate the prevalence of overweight and obesity in the children in the general population of the Murcia Region, using the body mass index (BMI) and applying the International Obesity Task Force (IOTF) criteria, and to compare these results with the ones obtained from other frequently used references in Spain. MATERIAL AND METHODS: The BMI of 178,894 children aged from 2 to 14 years was determined. The prevalence of overweight and obesity was compared to the IOTF, to the studies of the World Health Organization, as well as those of the Orbergozo Foundation (FO), and the Cross-sectional Spanish Growth Study (ETEC) references. The agreement between the different results was evaluated using the kappa index. RESULTS: The evaluation using the IOTF cut-off points gave an overweight prevalence of 20.6% (95% CI: 20.4-20.8), an obesity prevalence of 11.4% (95% CI: 11.2-11.5) and an overweight plus obesity prevalence of 32% (95% CI: 31.8-32.2), with this last one being higher in girls (33.2%) than in boys (30.9%). The highest agreement is between IOTF and FO-2011 (kappa=.795) and between FO-2011 and ETEC (kappa=.794). CONCLUSION: A high prevalence of overweight and obesity in children in the Region of Murcia was found. The ETEC and the FO-2011 study showed the highest agreement with the results obtained using the IOTF criteria.

[Costs and adherence to antiretroviral treatment]. / Costes y adherencia del tratamiento antirretroviral.

OBJECTIVE: To develop a system of data management that allows us to estimate the comparative effectiveness of the various antiretroviral treatment (ART) regimens. METHOD: Retrospective observational study in patients infected with HIV with stable ART. Adherence to treatment and unit cost for each patient's treatment was determined. The cost/patient/day was calculated and, multiplying by an adherence factor (fADH), the (cost/patient/day)(ADH). The comparison of both allowed us to obtain the Δcost/patient, which estimates the additional costs caused by lack of adherence. The incremental cost-effectiveness (iCER), grouping the results by the various coformulated drugs ("combos"). A study of the budgetary impact of these combos was carried out. RESULTS: 468 patients were evaluated (62% adherent). Average adherence was 88±18%. The average value of (cost/patient/day) (ADH) was significantly higher than the cost/patient/day (27.3±9.8€ compared to 24.3±7.6€. p<0.001). Just as with the f(ADH), no differences were found in the Δcost/patient between the different ART combinations. The combo with the least deviation from the cost/patient/day due to lack of adherence was that composed of abacavir/zedovudine/lamivudine (ABC/AZT/3TC,Δcost/patient=8.72±14.18%), and that with the greatest deviation AZT/3TC (Δcost/patient=13.52±17.68%). No significant differences were found in the iCER calculated for any combo. The ART that included abacavir/lamivudine (ABC/3TC) obtained the least budgetary impact. CONCLUSIONS: The greatest cost and percentage of adherent patients associated with the combos composed of Tenovovir/Emtricitabine(TDF/FTC) and ABC/3TC, and the least cost and effectiveness of those composed of AZT/#TC and ABC/AZT/3TC, does not allow us to identify any option as significantly dominant. The regimens with ABC/3TC were shown to be the most favourable from the combined point of view of cost and adherence.

[Physical sports activity in a representative sample of the population of Región de Murcia, Spain]. / Actividad física deportiva en una muestra representativa de la población de la Región de Murcia.

OBJECTIVE: To estimate the prevalence of intense physical activity according to age and sex in the region of Murcia, Spain, and to analyze its association with major demographic and socioeconomic determinants and other cardiovascular risk factors. METHODS: Survey of a representative sample of the population aged between 18 and 65 years from Murcia was performed using multistage random sampling with definition of the sample quotas. A total of 3091 individuals were surveyed. The frequency and duration of intense physical sports activity during the two weeks prior to the survey was obtained using a validated questionnaire. Information was also collected on socioeconomic variables, smoking, blood pressure, weight and height and a blood test was performed to determine plasma lipids. Intense or vigorous physical activity (> or = 6 Metabolic Equivalents [MET]) was measured in kcal/day and reduced to hours/week to give three categories: no vigorous physical activity, less than 2 hours/week, and 2 hours/week or more. RESULTS: Overall, 17.8% (95% CI: 16.6-19.0) of the adult population of the region of Murcia performed intense physical activity for > or = 2 hours/week. The figures were twice as high in men (23.1%; 95% CI: 21.0-25.2) than in women (12.5%; 95% CI: 10.9-14.1). In the logistic regression analysis, a higher frequency of intense physical activity was associated with age, level of education and employment situation. In men it was also associated with occupation and residence in urban areas. CONCLUSIONS: During the study period, one in five adults in the region of Murcia took intense physical sports activity with a frequency and duration that were compatible with the prevention of episodes of coronary ischemia.

Tissue transglutaminase antibodies in celiac disease: assessment of a commercial kit.

OBJECTIVE: Tissue transglutaminase was identified as the autoantigen eliciting endomysial antibody. A homemade enzyme-linked immunosorbent assay (ELISA)-based test was recently developed to determine quantitative titers of IgA antitissue transglutaminase antibody. Our objective in this study was to assess the suitability of a newly developed commercial kit for quantitative determination of antibody in patients with untreated celiac disease. MATERIALS: We tested serum samples from 79 untreated celiac patients, 42 healthy blood donors, and 18 patients with nonceliac intestinal disorders evaluated in two different centers. Samples were tested for antitissue transglutaminase, and antiendomysial and antigliadin antibodies in the center where diagnosis was performed. To assess interlaboratory variability of methods, 24 samples randomly selected were blindly tested in both centers. Antitissue transglutaminase antibodies were determined using a commercial kit (INOVA Diagnostics, Inc., San Diego, CA). RESULTS: Untreated celiac patients had significantly higher titers of antitissue transglutaminase than healthy and disease controls (p < 0.00001). According to the cut-off provided by the manufacturers (20 AU/mL), overall sensitivity was 92% (85% for one center and 100% for the other) and specificity was 98% (100% and 95%, respectively). Antiendomysial antibody was 86% sensitive and 100% specific. Discordance between antitissue transglutaminase and antiendomysial antibodies was detected in 13% of patients. Although two antitissue transglutaminase-negative cases had a positive antiendomysial antibody, the inverse situation was found in eight cases. A blind determination of antitissue transglutaminase on the same samples evidenced a good agreement (kappa statistic: 0.66) between both centers when assessment was qualitative (based on the decision of positive or negative). Although correlation of titers for both determinations was highly significant (r: 0.902, p < 0.00001), a very wide interlaboratory variability (median: 50%) was detected when absolute values were considered. CONCLUSIONS: The quantitative determination of antitissue transglutaminase using a commercial kit was highly sensitive and specific for detection of celiac disease. We observed an incomplete overlapping with antiendomysial antibody. The very high variability of values between laboratories still remains to be solved so as to propose the commercial ELISA assay for the screening of celiac disease.

[Quality assurance and teamwork in social medicine expert assessment exemplified by the expert assessment aid "corrective breast surgery" of the North Rhine Health Insurance Medical Service]. / Qualitätssicherung und Mitarbeiterpartizipation in der Sozialmedizinischen Begutachtung am Beispiel der Begutachtungshilfe "korrektive Mamma-Chirurgie" des MDK Nordrhein.

To standardise sociomedical expertising procedures in surgery of the breast a project team of medical advisors of the Medical Advisory and Expertising Service North Rhine worked out a manual. A form was created for sociomedical pre-advice occasions. Detail parameters for examination (time needed and advisor selection) were fixed in consent. Checklists were worked out, which may be admitted to quality assurance procedures. The manual "Medical opinion for surgery of the breast" has been implemented and is applied in the Medical Advisory and Expertising Service North Rhine since January 1999. In the sense of teamwork participation those who were involved as team-workers became participants in decision-making. The manual "Medical opinion for surgery of the breast" may be seen as an example of quality assurance and participation in socio-medical opinion procedures. The influence of this manual on the formal quality of medical opinion will be checked.

[Suicidal ideation and associated characteristics in adolescent women]. / Ideación suicida y características asociadas en mujeres adolescentes.

OBJECTIVE: To determine the prevalence of suicidal ideation and the symptomatic profile as well as to identify the sociodemographic characteristics highlighting female adolescents with the highest scores on suicidal ideation in adolescents living in Mexico City: students and suicidal patients. MATERIAL AND METHODS: A cross-sectional and ex-post-facto study was carried out in order to analyze information from two samples: 1,712 junior and junior high school women students (representative student sample in Mexico City), and 30 adolescents inpatient hospitalized for her suicide attempts (clinical sample). RESULTS: Prevalence of presence as well as persistence of suicidal ideation were higher in the clinical sample, nevertheless 11.8% of the school sample had everyone of the symptoms in a range of 1 to 7 days. The most persistent of the ideation symptoms was: "My family would be better if I were dead"; and in the clinical sample it was "I thought about killing myself". Finally, the sociodemographic characteristics that best matched the student girls having the highest scores in suicidal ideation were: to be on junior high school, to get low grades, to acknowledge school performance as bad and to have interrupted her studies. The characteristics that highlight the girls with a first attempt were analyzed in the clinic sample in comparison with those ones with two or more attempts. It was significant that girls in the second group were living only with one parent and they thought in the last attempt that their dead would be possible or certain. CONCLUSIONS: The prevalence of suicidal ideation was important in the school sample. If it is considered that this psychological construct has a strong association with suicidal attempt, and multiple suicide conduct, then is a priority to detect adolescents in risk and to make preventive efforts, considering the sociodemographic characteristics that configurate in risk for suicidal ideation.

[Examinations and referrals at a health center: a study of associated factors]. / Exploraciones y derivaciones en un centro de salud: estudio de los factores asociados.

OBJECTIVES: To determine the profile of the use of physical examination, further tests and referrals; and the impact which socio-family and behavioural factors, questions connected with patients' morbidity and other variables in health service use, have on these resources. DESIGN: Descriptive crossover study. SETTING: Urban health centre. PATIENTS AND OTHER PARTICIPANTS: 719 attendances of patients seen over a two and a half month period in two general medical clinics at the health centre were analysed. A questionnaire on health care was presented by the doctor to the patient at the end of the visit and also covered the activities and resources used during the visit. MAIN RESULTS: A multivariant analysis identified the factors which best explained variability in the frequency of physical examination as symptoms and, in particular, the type of consultation. None of the factors studied affected the use of analysis, radiology or referral to specialists. CONCLUSIONS: Symptoms and, in particular, the type of consultation are the factors which affect the use of physical examination. The scant relevance of other factors analysed and the comparison of our findings with other studies published suggest that the use of further examinations and referrals depend basically on other variables, such as those connected to the availability of resources and accessibility to them.

[Prior appointment, profile of the patient and accessibility]. / La cita previa, perfil del consultante y accesibilidad.

OBJECTIVES: To analyse the impact of the prior appointment system on still unevaluated care indicators and how the system connected with other factors affecting access to health care. DESIGN: Intervention study. SETTING: Santa María de Gracia Health Centre in Murcia. PATIENTS AND OTHER PARTICIPANTS: 831 and 724 patients seen at two general medical clinics at the health centre during the same period in two consecutive years, before and after the start of the prior appointment system. INTERVENTIONS: The start of the prior appointment system. A questionnaire given to patients at the end of their consultation. MEASUREMENTS AND MAIN RESULTS: Variables concerning patients' profiles and habitual conduct, resource use and distribution of waiting and consultation times, and health service use connected to other factors of access to care, were compared for before and after the introduction of the prior appointment system. There were significant differences in the distribution of waiting time, which became shorter (p < 0.01); and consultation time, with an increase in intermediate length and a decrease in extreme times (p < 0.05). Health service use also varied according to distance from the centre and place of residence of the patient: it increased for those living further away (p < 0.01). CONCLUSIONS: The prior appointment system, over and above a decrease in waiting time and increase in consultation time, meant a rationalisation of both time and health service use dependent on other factors connected with access to health care. The absence of modifications in patients' profiles and in their habitual conduct during the consultation were also confirmed.
