[Correlations between dietary salt intake and 24-h urine sodium excretion in a sample of the urban population of Cáceres]. / Correlaciones entre la ingesta de sal en la dieta y la eliminación de sodio en la orina de 24 h en una muestra de población urbana de Cáceres.

OBJECTIVE: Excessive salt intake is associated with higher levels of AHT and prevalence of cardiovascular diseases. WHO recommends consuming less than 5 g/day of salt (equivalent to 2 g Na+/day). Identifying foods and behaviours with greater contribution to excess intake would facilitate preventive dietary advice. DESIGN: Observational study. SITE: Urban Health Center in Cáceres. MAIN MEASUREMENTS: We estimated salt consumption using two food consumption frequency (FFQ) questionnaires, one generic and one with high Na+ content, and a 24 h follow-up survey. We use the Evalfinut program for nutritional evaluation of the diet. We analyzed correlations between estimated salt intake and 24-h urine sodium elimination (gold standard). RESULTS: 92% of the population had consumption higher than the recommendations with intakes equivalent to 9.5 g/day of salt (3.7 g/d of Na+). When sodium intake is determined by the Na+/K+ ratio, 79.54% have high intakes. Sodium elimination follows a slightly increasing trend with BMI. The perception of salt consumption is low, 56.3% consider it "adequate". 32.4% add salt to food once served. FFQ underestimate Na+ intake and targeted surveys provide higher values. The correlation between FFQ and Na+ urinary elimination is weak. CONCLUSION: We must reduce salt intake by increasing the perception of consumption, improving knowledge about the salt content in food and identifying target patients of the health council.

[Validity and limitations of methods to measure the intake and elimination of salt]. / Validez y limitaciones de los métodos para medir la ingesta y la eliminación de sal.

High blood pressure (HBP) is the main modifiable cardiovascular risk factor. HBP can be related to high salt intake. To measure intake, not all feeding surveys are comparable and valid. The reference procedure for assessing salt intake consists of measuring the urinary excretion of sodium in urine collected during 24hours, although alternative methods have been proposed, such as the collection of punctual and timed urine samples. In this review, we analyze which instruments allow the assessment of salt intake and which of them have provided greater validity and reliability through studies of concordance with the elimination of sodium in urine. Current food consumption surveys are inadequate because of their wide variability and relatively low correlation with the elimination of sodium in 24-hour urine. Its main limitation is the need for validation in different population groups. In primary care, salt intake should be assessed by using frequency-of-consumption questionnaires that collect foods with a high salt content, the consumption of preprepared dishes and questions that quantify the addition of salt in the preparation of food or at the table. For the validation of these questionnaires, the standard gold elimination of 24-hour urine sodium adjusted according to creatinine clearance should be used.

Prevalence of and Attitudes towards Smoking among Spanish Health Professionals.

BACKGROUND: The MPOWER strategy encourages suitable monitoring of the tobacco epidemic among health professionals in all countries. OBJECTIVE: To analyse the prevalence of and attitudes towards tobacco use among Spanish health professionals. METHODS: A study was conducted based on an online survey. The study population consisted of health professionals (primary care physicians, specialist physicians and nurses). The questionnaire used included questions about tobacco consumption, knowledge of and attitudes towards smoking. The sample size was calculated according to a database with 9,500 e-mail addresses and listings of health centres and hospitals all over Spain. Statistical analysis was done using the SPSS software programme. RESULTS: The study group comprised a total of 612 health professionals: 322 were women (52.6%), 196 were nurses and 416 were physicians. 11.7% of health professionals were smokers (9.6% regular smokers and 2.1% occasional smokers) and 41.3% were ex-smokers. Within the group of daily smokers, differences were observed between the nurses and the physicians: 11.2 versus 8.9% (p = 0.009). Smoking was recognized as a chronic disorder by 58.2% of health professionals, and 54.6% knew that the most effective intervention to help quit is a combination of psychological and pharmacological treatment. 56% of health professionals always asked their patients about their tobacco consumption. CONCLUSIONS: 11.7% of Spanish health professionals are smokers. We found that they have low knowledge about strategies to quit smoking and that there is a low level of therapeutic intervention on smokers.

Design of a Nutritional Survey to Detect High Dietary Salt Intakes and Its Usefulness in Primary Care Compared to 24-Hour Urine Sodium Determination.

Many population studies report salt intakes that exceed the WHO recommendation (2 g/day of Na+ or 5 g/day of salt). We do not have tools for detecting high salt intakes that are easy to apply in primary health care (PHC). We propose the development of a survey to screen for high salt intake in PHC patients. A cross-sectional study of 176 patients determines the responsible foods, and a study of 61 patients studies the optimal cut-off point and discriminant ability (ROC curve). We assessed the salt intake using a food frequency questionnaire and a 24 h dietary recall and used a factor analysis to identify the foods with the highest contribution to be included in a high intake screening questionnaire. We used 24 h urinary sodium as a gold standard. We identified 38 foods and 14 factors representing a high intake, explaining a significant proportion of the total variance (50.3%). Significant correlations (r > 0.4) were obtained between nutritional survey scores and urinary sodium excretion, allowing us to detect patients who exceed salt intake recommendations. For sodium excretion ≥ 2.4 g/day, the survey has a sensitivity of 91.4%, a specificity of 96.2% and an area under the curve of 0.94. For a prevalence of high consumption of 57.4%, the positive predictive value (PPV) was 96.9% and the negative predictive value (NPV) was 89.2%. We developed a screening survey for subjects with a high probability of high salt intake in primary health care, which could contribute to the reduction in diseases associated with this consumption.

[Prevalence alcohol consumption and cardiovascular risk factors in an Extremadura health area. Hermex study]. / Prevalencia de consumo de alcohol y factores de riesgo cardiovascular en un área sanitaria de Extremadura. Estudio Hermex.

OBJECTIVES: Alcohol has been associated with a lower risk of developing cardiovascular disease. It has been our objective to determine the prevalence of use of alcohol and its association with the presence of cardiovascular risk factors (CRF). DESIGN: Cross-sectional study. SETTING: Don Benito-Villanueva de la Serena health area (Badajoz). PARTICIPANTS: We selected a random sample of 25 to 79 year olds, representative of the population. METHODS: We collected a survey about the history of cardiovascular risk factors and alcohol consumption in the previous seven days. We measured blood pressure and a fasting blood sample was obtained. The association of alcohol consumption with the different CRF was studied by multivariate analysis, adjusting for different variables. RESULTS: A total of 2833 subjects participated, with a mean age 51.2 (SD 14.7) years and 46.5% males. We detected 36.1% (95% CI 34.4 to 37.9) of alcohol consumers. The overall prevalence and consumption medium or high risk was 63.2% and 15.2% in men, and 12.6% and 1.5% in women, respectively. In men, consumption of medium-high risk was associated with hypercholesterolemia, hypertension and smoking. In women, low-risk consumption was associated with a lower prevalence of obesity and hypertension and higher smoking. CONCLUSIONS: We found a lower prevalence of alcohol use, especially in women, compared to the Spanish national average. The consumption of medium-high risk mainly affects men and is associated with increased cardiovascular risk. In women at low risk consumption is associated with a lower prevalence of certain CRF and increased smoking.

Usefulness of The Piko-6 Portable Device for Early COPD Detection in Primary Care. / Utilidad del dispositivo portátil Piko-6 para la detección precoz de la enfermedad pulmonar obstructiva crónica en atención primaria.

INTRODUCTION: COPD is a highly prevalent but underdiagnosed disease, due to the limited availability of forced spirometry (FS) in primary care (PC). Microspirometers are inexpensive, easy-to-use devices that can measure FEV6 and FEV1/FEV6, and may help reduce underdiagnosis. The aim of this study was to validate the Piko-6 COPD screening device by demonstrating a good correlation with standard FS. METHODS: FS and Piko-6 determinations were made in 155 patients suspected of having COPD. The correlations, ROC curves, and Youden's index of both methods were compared, taking FS as the gold standard. RESULTS: FEV1, FVC and FEV6 correlation coefficients and FEV1/FVC and FEV1/FEV6 ratios were 0.87 (CI 0.836-0.909), 0.729 (CI 064-0.795) and 0.947 (95% CI 0.928-0.961), respectively. The ROC curve for FEV1 determined by Piko-6 achieved an area under the curve of 0.86 (95% CI: 0.78-0.92). Youden's index with a cut-off point of 0.70 for FEV1/FEV6 was 0.97. CONCLUSIONS: Piko-6 may be useful for COPD screening in PC. Measurements obtained with this device correlate well with those determined by FS, particularly the FEV1/FEV6 ratio. This, combined with its low cost and ease of use, may contribute to reducing COPD underdiagnosis, although its exact role in the diagnostic process remains to be determined.

[Continuous and momentous tobacco abstinence with pharmacologic therapy in clinical practice]. / Abstinencia puntual y continuada con el tratamiento farmacológico del tabaquismo en la práctica clínica.

BACKGROUND AND OBJECTIVE: The objective of the study was to evaluate the effectiveness of the pharmacological treatment of tobacco dependence according to the criteria established by SEPAR. PATIENTS AND METHOD: Longitudinal, prospective and multicentre study. We included smokers aged more than 18 years who attended 5 smokers clinics and received nicotine replacement therapy (NRT), bupropion or both. The punctual and continuous abstinence was studied at the 15, 30, 60, 90 and 180 days with each one of the proposed treatments. Effective results were defined as the intention to treat. RESULTS: There were 904 smokers, 476 males and 428 females, mean age 42.51 (10.09). Of the 904 individuals who started the treatment, 820, 776, 687, 719 and 679 were present at the follow-up sessions at 15, 30, 60, 90 and 180 days, respectively. The punctual global abstinence at 15 and 180 days was 65.6% and 43.1%, while the continuous one was 57.4% and 38.8% at two and six months, respectively. Significant differences were not observed with regard to the punctual or continuous abstinence among patients treated with NRT, bupropion or both. CONCLUSIONS: The pharmacological treatment of tobacco dependence used individually according to the recommendations of the clinical guidelines allows to obtain good results with regard to the momentous and continuous abstinence. The effectiveness of the different first line treatments is similar in all the phases of the therapeutic process.

[The importance of longitudinality, comprehensiveness, coordination and continuity of nursing home care]. / La importancia de la longitudinalidad, integralidad, coordinación y continuidad de los cuidados domiciliarios efectuados por enfermería.

Home care is essential for dependent persons, in order to support the high levels of morbidity, for the elderly as well as their caregivers, as it enables patients to remain in their familiar environment as long as possible, fulfilling the wish expressed by most of the population. Home care is the activity that best represents the essential attributes (longitudinality, comprehensiveness, continuity, coordination) of the primary, and that suffers most when these attributes are not included in the activities undertaken by primary care teams, or due to cuts in health-care. Home care requires highly skilled, versatile and committed nursing staff, with whom the population identifies as a source of care, and where they are assessed for their relevance and effectiveness. Nurses with wide clinical care skills, with a balanced content of treatment and prevention, and the freedom to develop their work, are needed in order to continuously monitor the health problems of their acute and chronic patients, in the family and community.

[Adequacy of medication in patients 65 years or older in teaching health centers in Cáceres, Spain]. / Adecuación de la prescripción farmacéutica en personas de 65 años o más en centros de salud docentes de Cáceres.

BACKGROUND: The appropriateness of drug prescription is objective of the National Health System for the sanitary and economic repercussions linked. The main objective of this paper is to analyze the appropriateness of drug prescription on patients 65 years or older and identify the most prevalent prescribing errors. DESIGN: Observational, descriptive, transversal, multicenter study in Health Centers doctors in training in Cáceres. 471 patients 65 years or older were included by convenience samplin.The sample size was calculated to an accuracy 3.5%-5% and a confidence level 95%. The measured variable was the criteria STOPP/START. We calculated mean and standard deviation for quantitative variables and relative frequencies for qualitative variables. RESULTS: The most frequent STOPP criteria were: duplication of drugs (9.76% CI 95% 7.40 to 12.78), prolonged use of long-acting benzodiazepines (7.22%, 95% CI 5.21 to 9, 92) and the use of aspirin in patients without cardiovascular secondary prevention (7% 95% CI 5.03 to 9.68). The most frequent START criteria were: omission of antiplatelet agents and statins in diabetes coexisting one or more cardiovascular risk factors (9.34 and 7.03 to 12.31% 95% 95% 4.46% 2.93 to 6, 72), calcium and vitamin D in osteoporosis (5.31%, 95% CI 3.61 to 7.72) and metformin in type 2 diabetes metabolic syndrome ± (4.46%, 95% CI 2.93 - 6.72). CONCLUSIONS: The main inappropriate prescribing concerns treatments that should be suspended or modify. The duplications were the most common cause of inappropriate prescribing, being more frequently involved drugs like benzodiazepines, NSAIDs and drugs in drugs associations. The second cause of inadequacy most prevalent was the prescription of benzodiazepines with long half life. The third most common cause was acetylsalicylic acid, both through overuse or omission.
