Mírame a los ojos y dime la verdad: La carga cognitiva asociada a una mentira puede ayudar a desenmascararla
Karlos Luna,Beatriz Martín-Luengo
Ciencia Cognitiva : Revista Electrónica de Divulgación , 2010,
Abstract: Distinguir cuándo una persona miente o dice la verdad es muy difícil. Investigaciones recientes sugieren que crear y mantener una mentira supone un considerable esfuerzo cognitivo, y que ese esfuerzo puede ser observable, ayudando a detectar las mentiras. Cuando se aumenta la carga cognitiva de los participantes mediante la simple instrucción de mirar a los ojos del entrevistador, los interlocutores pueden cazar al mentiroso por encima del nivel de azar.

Abstract: memory tests are frequently used to measure the effectiveness of an advertisement. however, as different tests provide different kinds of information it is important to know which type of test is the most appropriate. the main objective of this investigation was to study the effect of different memory tests on the number of brands recalled and the level of interest generated by them. a group of participants wrote down all the brands of any kind of product that they remembered having seen advertised (free recall test) and rated their interest in each brand. subsequently, the participants were given a list of 27 categories and wrote down the brands they associated with the categories (cued recall test) and also rated their level of interest. the results showed that although the participants generated more brand names with the cued recall test, the brand names mentioned in the free recall test generated greater interest. these results highlight the importance of choosing the correct memory test to measure the effect of publicity.

BMC Cardiovascular Disorders , 2009, DOI: 10.1186/1471-2261-9-35
Abstract: A prospective case-control observational study was performed. From a series of 950 consecutive patients followed up during 42 months, 48 patients with resistant hypertension were detected. 232 patients with controlled high blood pressure were also included.No differences were observed in the distribution of G894T (Glu298Asp) NOS3 genotypes between the resistant hypertension group and the controlled hypertension patients. However, genotype -786CC was more frequent in the group of patients with resistant hypertension (33.3%) than in the group of patients with controlled high blood pressure (17.7%) (p 0.03). Furthermore carriers of allele T (-786TC and -786TT) were more frequent in patients with controlled hypertension (82.3%) than those with resistant hypertension (66.7%) (Multivariate analysis; RR 2.09; 95% CI 1.03–4.24; p 0.004).Our results indicate that genotype -786CC of the NOS3 gene increase the susceptibility to suffer resistant hypertension, which suggest that resistance to conventional therapy could be determined at the endothelial level.Hypertension may be termed resistant when a therapeutic plan that has included attention to lifestyle measures and the prescription of at least three drugs including a diuretic in adequate doses has failed to achieve goal blood pressure (BP) defined as a systolic/diastolic pressure of < 140/90 mmHg or < 130/80 mmHg in diabetics patients [1]. The prevalence of "true" resistant hypertension (excluding secondary causes of hypertension, white coat hypertension, inadequate doses, etc) is less than 5% of the general hypertension population [2]. In general, resistant hypertension has been reduced to an issue of treatment adherence or suboptimal treatment.Genetic determinants of human hypertension are poorly understood although polymorphisms in several genes have been associated with elevated blood pressure levels. However, there are only few studies that consider resistant hypertension from a genetic point of view [3-6].Causative ge

Abstract: the epidemiology of candidemia in the servicio autónomo hospital universitario de maracaibov(sahum) was studied. from january 2008 to march 2010, 78 candidemia episodes from 70 patients were analyzed. ages ranged from 15 days to 80 years old. patients were hospitalized in different wards at sahum. candida spp was isolated in blood cultures processed at the bacteriology reference center (crb). for species identification, chromogenic brilliance candida agar and vitek-ybc were used. additionally, the cultures were evaluated by traditional methods at the mycology laboratory, university of zulia. patients? characteristics were obtained from the crb register. the median patients? age was 17 years old. eight sequential isolates were obtained. the following candida species were found:, c. parapsilosis 51.28%, c. tropicalis 15.38%, c. guilliermondii 11.54%, c. albicans 10.26%, c. famata 6.41%, c. glabrata 3.85% and candida krusei 1.28%. x2 showed that children in non-icu wards were more likely to have candidemia. a change in the frequency of the species isolated was observed; for this reason, a permanent surveillance system is required.

Abstract: for the purpose of studying the predisposition factors in patients in the acquisition of candida albicans in the urinary tract, retrospective research was undertaken in the university hospital in maracaibo from 1999-2001. for such a purpose a sample of 53 patients was taken: 28 showing the presence of candida albicans (ca+) and 25 that did not show it (control), with an average overall age of 42. the variables studied were sex, time of hospitalization (th), permanence in an intensive care unit -uci- (iu), use of bladder catheter (sv), bladder catheter usage time (tcsv), use of antibiotics (ua), duration of the use of antibiotics (tuab) and number of antibiotics used (nab). the data was registered in a questionnaire type instrument. the statistical analyses of the results showed that in ca+ patients, the variables: th, tcsv, tuab, nab, iu and female (sex), were more frequent than the averages of each one of these variables in the ca- group. the discriminative analysis for the same variables allowed for the establishment of statistically significant relation with variables tcsv, tuab and nab; although the last variable did not have any influence in the model when the discriminative equation was analyzed. the ji-square test indicated that there was dependence for the feminine sex, tcsv was greater at 10 days, nab was greater or equal to 2, tuab was greater at 14 days. early removal of the bladder catheter and the adequate use of antibiotics during hospitalization, are practices that help to prevent the acquisition of c. albicans in hospitalized patients.

Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.34077
Abstract:

Objective: The aim of this study was to compare laparoscopic (LPS) and laparotomy (LPT) approaches for endometrial cancer, and to assess intraoperative and postoperative results, disease-free survival and overall survival. Methods: We designed a prospective observational study, every patient diagnosed of endometrial cancer and subsidiary to surgical staging was included. Total hysterectomy, bilateral adnexectomy, pelvic lymphadenectomy were performed in every case. Paraaortic lymphadenectomy was performed depending on tumor histology. Results: 70 patients with endometrial cancer were enrolled, 49 (70%) were treated laparoscopically and 21 (30%) laparotomically. There was not statistical significant difference in the mean operative time, it was 183.06 ± 21.03 min (range 120 - 230) in the LPS group and 195.24 ± 28.39 min (range 130 - 240) in the LPT group, mean difference 12.16 (95% CI 0.2 - 24). There was no difference in the number of lymph nodes resected. Mean blood loss was lower in the LPS group. There were less postoperative complications, 3 (6.12%) in the LPS group and 7 (33.3%) in the LPT group (p < 0.01). Mean hospital stay was significantly shorter in the LPS group 4.29 ± 1.62 days vs 8.81 ± 3.37 days in the LPT group (p < 0.01), mean difference 4.52 (95% CI 3.3 - 5.7). Overall survival was similar in both groups. Conclusion: Laparoscopic approach for endometrial cancer offers similar results in terms of survival and oncological radicality as the laparotomic approach and a lower rate of complications, a quicker convalescence time and a shorter hospital stay.

Abstract: Leukocytary DNA from 195 PD patients and a control group of 231 unrelated healthy individuals was studied for the nonsynonymous HRH1Leu449Ser and the promoter HRH2G-1018A polymorphisms by using amplification-restriction analyses.The HRH1Leu449Ser amino acid substitution was identified in two women with late-onset PD whereas it was not observed among healthy subjects. The HRH2G-1018A polymorphism was observed with allele frequencies = 3.59 (95% CI = 1.74–5.44) and 5.0 (95% CI = 3.00–6.96) for patients with PD and healthy controls, respectively. These frequencies were independent of gender and age of onset of the disease. Multiple comparison analyses revealed that differences were not statistically significant.These results indicate that the polymorphisms analyzed are not a major risk factor for PD, although the HRH1Leu449Ser amino acid substitution might be related to PD.Histamine is involved in neuronal degeneration [1] and neurotoxicity [2]. Changes in the morphology and increase in density of histaminergic fibers in the substantia nigra have been described in the brain of PD patients [3]. It has been shown that histamine causes selective damage in the dopaminergic neurons of the substantia nigra with induction of inflammatory signal processes [4]. Among patients with PD, blood histamine levels [5] and the concentration of the histamine metabolite pros-methylimidazoleatic acid in the cerebrospinal fluid are increased [6], and recently we described the association of genotypes leading to high histamine metabolism with increased risk to develop PD [7]. Taken together, these findings suggest that modulation of brain histamine may be related to PD, but the mechanisms underlying such modulation remains unknown.Changes in the density and expression of histamine receptors (HRH) have been detected in PD patients [8]. HRH antagonists bring about improvements in motor and other symptoms [9,10], thus suggesting that HRH play a role in the clinical response of PD patients. Sin
