Objective: To evaluate the association and risk of hypercholesterolemia among adult patients with prediabetes treated at a medical center in the district of Villa El Salvador in Lima, Peru. Materials and methods: An analytical, prospective and cross-sectional study conducted with data from medical consultation records of 749 patients treated at a polyclinic in the district of Villa El Salvador in Lima, Peru. Asymptomatic adult patients who had routine and preventive checkups were included in the research. Patients with endocrine and metabolic disorders or being treated with hypoglycemic drugs were excluded. The study variables were sex, hypercholesterolemia and prediabetes. The association analysis was performed using the chi-square test and the risk was evaluated by means of the odds ratio. In addition, the multivariate analysis was conducted through a binary logistic regression, and an alpha value of 0.05 and a confidence level of 95 % were considered as the cut-off point to determine the statistical significance. Results: There was a statistically significant association between prediabetes and hypercholesterolemia. Females with prediabetes were 1.66 times more likely to develop hypercholesterolemia than females with normal baseline glucose levels, while males with prediabetes were 2.37 times more likely to have high cholesterol than males with normal baseline blood glucose levels. Conclusions: Prediabetes is associated with hypercholesterolemia, thus increasing its risk. It is justifiable to carry out the joint measurement of fasting total cholesterol and baseline glucose in disease prevention and health promotion campaigns,regular checkups and follow-up of patients with risk factors for diabetes, prediabetes and hypercholesterolemia. This helps reduce the hemodynamic and cardiovascular consequences of high cholesterol levels and the worsening of the joint morbidity and mortality of chronic hyperglycemia. [ABSTRACT FROM AUTHOR]

Introduction: chronic kidney disease affects a great part of the population in the world. Its diagnosis in the initial stages allows a better management of the disease, better prognosis and better quality of life. Objective: to compare the health status of patients with chronic kidney disease at the time of starting hemodialysis according to the influence of early or late remission to the Nephrology Specialist. Methods: a descriptive and cross-sectional observational study was carried out on a population of 348 patients who started renal replacement therapy in hemodialysis at the "Arnaldo Milián Castro" Hospital during the study period; the Chi-square distribution was used for statistical analysis. Results: there was a predominance of male patients, older than 60 years old, with a late referral to hemodialysis. In 40.8% of the cases the cause was diabetes and 65.56% of the late referrals required an urgent dialysis. In both study groups were showed alterations in hemochemistry values and glomerular filtration rate and albumin were those with more variability. Patients with tardy referral were those who presented more comorbidities and 51.5% were not dispensed. Conclusions: patients with a late remission to the Nephrology Specialist are those who most need emergency hemodialysis and emergency temporary vascular access, as well as those who most often have hypertension associated with their underlying disease, and most of them are not seen by their family doctor.

With the objective of modeling the anthracite crushing process in cone crusher, was taken as starting point the Whiten model, replacing the classification and breakage distribution functions for those that were proposed by Whiten and White (1979) and Austin and Luckie (1972) respectively. The determining of both functions and their coefficient identification was done using algorithm developed by Hechavarría (2011). Results show that the classification function follows the same regularity that those that was determinate by Vogel and Peukert (2005) and Coello et al. (2011). Different particle size accumulative breakage distribution functions confirmed Austin theoretical model validity. Correlation coefficient (0, 9826) and Chi-square results confirm modified Whiten model validity for modeling the anthracite crushing process of CIS crushing mobile installation from Nicaro.

Engineering, within its academic and application forms, as well as any formal research work requires the use of statistics and every inferential statistical analysis requires the use of values of probability distribution functions that are generally available in tables. Generally, management of those tables have physical problems (wasteful transport and wasteful consultation) and operational (incomplete lists and limited accuracy). The study, "Probability distribution function values in mobile phones", permitted determining - through a needs survey applied to students involved in statistics studies at Universidad de Nariño - that the best known and most used values correspond to Chi-Square, Binomial, Student's t, and Standard Normal distributions. Similarly, it showed user's interest in having the values in question within an alternative means to correct, at least in part, the problems presented by "the famous tables". To try to contribute to the solution, we built software that allows immediately and dynamically obtaining the values of the probability distribution functions most commonly used by mobile phones.

The colorectal cancer (CRC) is currently the fourth cause of cancer death in Chile. Its incidence, however, is continuously increasing in our population. The aim of this study is to describe morphological and clinical aspects of patients resected CRC. Retrospective cohort study. We studied 322 patients operated on for CRC between 1987 and 2003 in the Hernan Henriquez Aravena Hospital of Temuco. The clinical and morphological variables studied (all analyzed for subgroups of subjects with tumors of the colon and rectum) were age, gender, tumor location, tumor size and shape, level of infiltration, histological type, histological differentiation grade and tumor involvement lymph node. We used descriptive statistics and analytical, using Pearson chi-square and Fisher exact tests for categorical variables and T-test for continuous variables. The median age was66 years, with average age of the right colon tumors (RC), transverse (TC), left (LC) and rectum was 62.2, 64.6, 64, and 64.4 years respectively (p = 0.53). In RC and LC were observed 57% and 47% of women, respectively (p <0.05). 69% of the cases corresponded to tumors of the colon (24% RC, 4% TC and 41% LC) and 31% to cancer of the rectum. The average tumor size was 67.2 ± 33.1 mm RC, 53.5 ± 19.7 mm. TC, 44.1 ± 22.3 mm LC and 41.5 ± 17.5 mm in the rectum (p <0.001). On RC as Bormann type I was observed in 57% while the LC annular and ulcerative lesions 45% CI. We found 75% of moderately differentiated tumors, corresponding to 82% adenocarcinomas, 16% and 2% mucinous adenocarcinoma cell carcinoma signet-ring. 76% were T3 and T4 tumors. We found lymph node tumor involvement in 39% of which 95% were T3-T4 tumors. We checked at the regional level for patients with CRC clinical and morphological variables described in the literature.

Background: Human papillomavirus (HPV) is the main risk factor for the development of cervical cancer, which remains the most common malignancy in our country. There are studies in which immunosuppressed patients have an increased risk of suffering an infection by HPV. Objective: To determine the prevalence of HPV infection in patients with rheumatoid arthritis (RA) compared with women matched by age in an open population. Materials and methods: A cross-sectional, comparative, and observational study in women with RA and women without rheumatic disease to whom cervical cytology, HPV detection and typing were performed. Data were analyzed using Chi2 test, Fisher's exact, Mann-Whitney and odds ratio. Results: The study included 77 women with RA matched by age and 77 women without RA. The frequency of HPV infection in 37 patient with RA (48%) against 17 women without RA (22%) [OR 3.1551 95% (1.56 - 6.35) p = 0,001]. HPV types 83 and 59 were more frequent in women with RA, while in the controls, types 59, 81 and 54 were found. No relation with the duration of the disease, steroid use, or immunosuppression was found. Conclusions: HPV infection is more common in women with rheumatoid arthritis compared to those women without rheumatic disease. [ABSTRACT FROM AUTHOR]
