- Abstract
Invasive meningococcal disease is challenging for public health, mainly when it manifests with sudden changes in incidence, serogroups and hypervirulent clones that spread in the population, causing great alarm due to its sequelae and often fatal course, a situation that occurred in Chile, starting at week 26 of the year 2012. To face this scenario, an organization of multidisciplinary teams was required, called W-135 Action Plan in Chile, which included sanitary alerts, education, reinforcement of the epidemiological surveillance of suspicious cases, immediate diagnosis through state-of-the-art techniques, blocking of contacts, communication plans, and, from the 42nd week, ON the vaccination campaign was started for children aged from 9-months-old to less than 5 years of age. The vaccination strategy had a great impact on the decrease in incidence (1.3 to 0.1/100,000) and case fatality rate in the vaccinated population (23% to 0%), with a high safety profile, leading to its subsequent inclusion in the national immunization program. The ability to develop molecular, clinical and epidemiological studies allowed us to better understand the situation, supporting public health policy decisions for its control. The W-135 Action Plan implemented by the Ministry of Health in Chile, to manage the outbreak of meningococcal disease by Neisseria meningitidis serogroup W, demonstrated that the coordination of these efforts, through an organized Action Plan, allows the implementation of campaigns at the national level achieving high coverage of risk populations in short periods of time, generating a positive impact on the health of the population.

- Abstract
Background: Lack of adherence to treatment may hamper the management of type 2 Diabetes Mellitus. Aim To identify if there is a profile of psychological variables associated with adherence to treatment and complications in patients with type 2 diabetes mellitus., Material and Methods: The psychometric instruments Multidimensional Scale of Locus of Control in Health, Locus of Control of Rotter and Inventory of Temporary Orientation of Zimbardo & Boyd were applied to 192 patients aged 64 ± 10 years (78% women) with type 2 diabetes attending public primary health clinics. Adherence to treatment was assessed using glycosylated hemoglobin levels., Results: There was an inverse association between glycosylated hemoglobin and adherence to treatment (p < 0.01). Adherence in patients with renal damage and diabetic foot was associated with the psychological variables Negative Time Perspective Profile (p < 0.05) and External Locus of Control Powerful Other (p < 0.05)., Conclusions: A psychological profile associated with adherence was observed in the presence of kidney damage and diabetic foot. A fatalistic present and a negative past are the outstanding features of a negative temporal profile.

- Abstract
Background: Health literacy is defined as the degree to which individuals obtain, process and understand basic health information and services. It is necessary to make appropriate decisions about their health. Evidence has shown that the level of health literacy is critical to the prognosis of chronic diseases. The Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA-50) is a short and simple health literacy adult assessment., Aim: To determine the validity and reliability indicators of SAHLSA-50 in Chilean adults., Material and Methods: The survey was applied to 84 older adults living in high and low income neighborhoods., Results: The survey had an adequate construct validity and reliability, its Comparative Fit Index was 0.93, its Tucker-Lewis index was 0.927 and its Root Mean Square Error of Approximation was 0.044. Close fit was not statistically significant (p = 0.828). Reliability was estimated by K-Richardson, which reported a good outcome (0.9255). Despite the good global indicators obtained, it is necessary to pay attention to some items that would fail to explain the Health literacy construct or were beyond the parameters of difficulty and discrimination proposed by the authors of the test., Conclusions: We propose this test as a useful tool to assess health literacy in the adult population in Chile. Its use and incorporation into local research can be especially recommended in the areas of education and health promotion.

- Abstract
Healthcare-associated infections (HCAI) are a problem worldwide. In our country, the estimated incidence of HCAI is 70,000 per year. This results in an increase in the average length of hospital stay by 10 days per patient, an estimated annual cost of US $ 70 million and an overstay of 700 thousand bed days a year. For over 30 years stethoscopes have been considered as potential HCAI vectors, since pathogens like methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus strains adhere and colonize them. These organisms can be transmitted between patients if the instruments are not sanitized. Several studies conclude that disinfecting the stethoscope with isopropyl alcohol eliminates up to 99% of bacteria. Simple, economic measures such as implementation of guidelines for stethoscope disinfection are a clear opportunity for preventing infections.

- Abstract
C(2) Cyclosporine (CsA) level, as a surrogate of area under the time-concentration curve (AUC) 0-4 hours, is a good predictor of drug absorption and clinical outcome after kidney transplantation. It has been difficult to define the optimal C(2) level in the individual case and given the broad range of C(2) due to interindividual absorption variability it has been troublesome to determine the drug dose needed to obtain an expected C(2)-CsA concentration. In this study data of 16 stable renal and renal/pancreas recipients treated with prednisone, azathioprine, and CsA (Neoral) managed by C(0) level was examined. CsA concentrations at time 0 (basal), 2, 6, and 12 hours post CsA (Neoral) intake were determined the day of the study. A significant linear regression level was established between C(2) (but not C(0), C(6) and C(12)) and the dosage expressed as mg/kg/d (P = 0.0113, correlation coefficient r = 0.573018). Subsequently, another 27 renal transplant recipients were studied retrospectively and divided into three groups according to posttransplant period: 1 to 6, 7 to 12, and beyond 12 months after transplant. Equations derived from the relationship between C(2) and dose (mg/kg/d) were similar between the three groups and when compared with the first study. A formula obtained from the 27 patients in the whole posttransplant period (mg/kg/d = C(2) x 0.0010208 + 1.86125) was applied to patients of the first study obtaining a regression coefficient between actual and calculated CsA dose of 0.6145 (P = 0.01). A more accurate equation (P = 0.0001, r = 0.5925) was obtained by analyzing 145 C(2) determinations covering a period from 1 month to 8 years following transplant which gave a linear regression line defined by the equation C(2) x 0.001473 + 1.6673. This equation would permit the calculation mg/kg/d of CsA (Neoral) dose to obtain an expected C(2) level. The derived equation shown in this paper has a predictive value of 50% to 60% only, but can help to find adequate dosage in the presence of an inappropriate C(2) level.

- Abstract
Background: Hypertension is a common and important cardiovascular risk factor in patients on chronic hemodialysis., Aim: To report the prevalence and characteristics of hypertension among patients on chronic hemodialysis., Patients and Methods: Cross sectional study of 313 patients (192 male, aged 57 +/- 18 years) dialyzed in 7 representative centers in Santiago, Chile., Results: Patients were on hemodialysis for a mean of 68 +/- 53 months and 67 (21%) were diabetic. 230 (74%) were hypertensive and 223 of these (97%) had predialysis hypertension. A multivariate analysis showed that hypertension was associated with increased weight gain between dialysis, failure to achieve the postdialysis dry weight, increasing age and the presence of diabetes. Among hypertensive patients, 61% were receiving antihypertensive medications, compared with 27% of patients with normal blood pressure., Conclusions: High blood pressure is highly prevalent among patients on chronic hemodialysis and is associated to hypervolemia, age and the presence of diabetes.
