Therefore, the objective of the study was to identify the relationship between depression symptoms of the informal primary caregivers and the dependency that they perceive in the person who is being taken care of. The study design was non-experimental, cross-sectional and correlational. The sample was intentional non-probabilistic of 259 informal caregivers. Three data-collection instruments were used: the Patient Health Questionnaire, the Depression Scale (PHQ-8), and the Barthel Scale, which is used for measuring the capacity of a person to carry out 10 basic everyday activities. The average age of the caregivers in this study was 49.6 years, with a predominance of the female sex (82.6 %), and most of the patients’ caregivers were their daughters (38.2 %). The caregivers’ perceived percentage of dependence was placed in the moderate dependence category, with 32.4 %. Results show a small but significant correlation (r = - 0.159, P = 0.010) between dependence and symptoms of depression. The group of caregivers of people with severe dependence showed greater depressive symptoms than their caregiver peers of people with moderate dependence (P = 0.014). Informal primary caregivers reported greater depressive symptoms when they perceived more dependence in their relatives with chronic illnesses.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46938420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to develop a predictive model of sexual infidelity behavior among married persons through the analysis of seven variables related to the infidelity construct. A sample of 790 married persons (53.4 % women and 47.6 % men) was collected in Monterrey, Mexico, using random route sampling. The Relationship Assessment Scale, Sexual Satisfaction Index, Attitude toward Marital Exclusivity Scale, Unfaithful Behavior Scales, Sexual Sensation Seeking Scale, and Marital Aggrandizement Scale were applied. A model with 2 correlated exogenous variables (sexual sensation seeking and marital aggrandizement) and 5 endogenous variables (attitude towards infidelity, marital satisfaction, sexual satisfaction, desire for sexual infidelity, and sexual infidelity behavior) was specified. Six out of 100 participants were dissatisfied with their marriage and 13 with sexual relations with their partner; 20 saw more defects than virtues in their partners. In addition, 83 informed not engaging in sexual infidelity behaviors, 60 indicated total rejection towards own sexual infidelity; 72 showed no desire for sexual infidelity; and 51 reported not seeking sexual sensations. The model showed a large effect on the sexual infidelity behavior, explaining 70.8 % of its variance, and had a close fit: X2(7) = 11.93, P-value = 0.10, RMSEA = 0.03, and SRMR = 0.01. It is concluded that the most critical variable in the model is the desire for sexual infidelity, whose most important determinant was the sexual sensation seeking. The negative correlation between this last variable and marital aggrandizement indicates that these 2 variables can be modulated one to the other. Furthermore, the model highlights aspects of marital and sexual dissatisfaction.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42358671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, 3 05 samples of vaginal discharge from pa tients of the ISSSTE Puebla Regional Hospital were analyzed. The samples were processed and analyzed for the diagnosis of BV following the recommendations of the Amsel, Nugent and Ison-Hay methods. The analysis of the results indicated 12.8 % by Nugent, 31.1 % of BV by the Amsel method and 36.7 % by Ison-Hay; suggesting that both techniques show a high rate of false positives. The sensitivity for the Amsel and Ison-Hay method was 97.44 %, the specificity was 78.57 % and 72.18 % for Amsel and Ison-Hay, respectively. In conclusion, given the results obtained and the minimal differences between the analyzed methods, it is recommended to perform the Amsel criteria, followed by the observation of Gram staining of the vaginal flow for the assessment of the microbiota by the Ison-Hay method, to have a better diagnosis of BV, when the Nugent method is not used.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41998897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Saccharomyces yeasts are conventionally used as probiotics and there are reports that use native strains such as Candida norvegensis. The objective of this study was to evaluate the effects of the probiotic of Candida norvegensis on the in situ ruminal dry matter degradability of corn stover and on the productive performance of growing lambs. In the first experiment, the yeast Candida norvegensis (strain Levazoot 15) [0 g (T1)] and 5 g (T2) was used to determine the in situ ruminal dry matter degradation (RDMD) of the corn stover in 3 cows with cannulas in the rumen, which was determined by the polyester bag technique. There was no effect of yeast (P > 0.05) on fraction (a), (b) and (a+b). However, the effective degradability at 1 %/h and 5 %/h of ruminal turnover was higher in T2 (P < 0.05). In the second experiment, 32 lambs were randomly assigned to individual pens for 105 d to evaluate 4 diets that differed in the proportion of concentrate: forage: T1 = 75: 25, T2 = 75:25; T3 = 50: 50, and T4 = 25: 75. With the exception of T1, the diets were supplemented with Candida norvegensis at 15 mL/kg of live weight, equivalent to 5 g/d of yeast in dry matter basis. The lambs in the diet with 75 % of concentrate plus the yeast (T2) showed greater weight gain and best feed conversion (P < 0.05). It is concluded that Candida norvegensis showed beneficial effects on ruminal degradability and on the growth of lambs.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49374930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deterministic models developed for single-phase flows require the adjustment of empirical constants and cannot be extrapolated to biphasic flows, where the flow pattern generated in the system significantly influences the behavior of the total flow and the frictional pressure losses. Therefore, in this paper, we present a model to describe the behavior of the biphasic flow in relation to the flow pattern and the morphology, dimensions, and operating conditions of the porous bed, whose obtainment was based on a hierarchy that used the equations for conservation of momentum, fractal geometry and fractional differential calculus jointly. The model predicts that, for the same composition of the biphasic flow, the flow pattern significantly influences friction pressure losses, with an increase when one of the phases is dispersed within the other. On the other hand, the increase in the fractal dimension of the pores, in turn, causes an increase in pressure loss due to friction. The model has limitations associated with the considerations established during its collection, since it is only valid when the effects of surface tension are more significant than the gravitational effects, the effects of the latter being disregarded on the flow pattern, as well as for the stationary state.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46389620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work is to present a diagnosis of the uses and appro priations of digital platforms among young people in the southern region of Tamaulipas, Mexico, among high school and college students. The methodology is quantitative, based on a descriptive non-experimental design. A statistically representative sample from the municipalities of Tampico, Ciudad Madero, and Altamira, was designed with a 95 % accuracy and a margin of error of +/- 2 %. A questionnaire was developed and administered to a sample of 1 222 young students, in which the intensity of use and navigation profile of various digital platforms was evaluated. These platforms include general information pages, information or product exchange, digital social networks, educational and learning sites, as well as entertainment. The findings show that two fundamental elements mediate the processes of use and appropriation of digital platforms: a technical component, related to the interactivity resources provided by the platform itself, and a socio cultural component that relates to the life story, social and cultural capital, personality and expressive capacity, as well as the digital skills and intrinsic motivations of young people. In conclusion, this study allows us to problematize the phenomenon of the appropriation of digital platforms from the local level and to propose intervention routes that take advantage of the identified potential of digital skills, collaboration and content production.","PeriodicalId":42451,"journal":{"name":"CienciaUat","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48919424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multitemporal analysis showed a clear trend in the reduction of vegetation cover (- 6.53 %) and of areas devoid of vegetation (- 1.71 %). Likewise, the results also highlight a significant increase of agricultural land (+ 7.61 %), which seems to be unassociated with the increase of human settlements (+ 0.08 %).
