The meaning of touch the prostate for man: the nurse in health promotion

Objectives: To identify the meaning for the men on the clinical examination of digital touch Prostate cancer early detection, to characterize the cause of the deficit in the search for preventive examination and health services by men and discuss the nurse's role in promoting men's health. Method: Qualitative descriptive study with field research guided by semi-structured form. Results: The meanings attributed to the digital touch of the prostate were embarrassment, discomfort, stigma and important. The information and access are tied to socioeconomic factors of the participants. Conclusion: Nurses should assist in health education and comprehensive health care by standardizing the information for different socioeconomic groups, minimizing the stigma and embarrassments, highlighting the importance of self care for man, to improve the search for health services, screening exams and prevention

Compactness and invariance properties of evolution operators associated with Kolmogorov operators with unbounded coefficients

In this paper we consider nonautonomous elliptic operators ${\mathcal A}$ with nontrivial potential term defined in $I\times\mathbb R^d$, where $I$ is a right-halfline (possibly $I=\mathbb R$). We prove that we can associate an evolution operator $(G(t,s))$ with ${\mathcal A}$ in the space of all bounded and continuous functions on $\mathbb R^d$. We also study the compactness properties of the operator $G(t,s)$. Finally, we provide sufficient conditions guaranteeing that each operator $G(t,s)$ preserves the usual $L^p$-spaces and $C_0(\mathbb R^d)$

Black holes in asymptotically Lifshitz spacetimes with arbitrary critical exponent

Recently, a class of gravitational backgrounds in 3+1 dimensions have been proposed as holographic duals to a Lifshitz theory describing critical phenomena in 2+1 dimensions with critical exponent $z\geq 1$. We numerically explore black holes in these backgrounds for a range of values of $z$. We find drastically different behavior for $z>2$ and $z2$ ($z<2$) the Lifshitz fixed point is repulsive (attractive) when going to larger radial parameter $r$. For the repulsive $z>2$ backgrounds, we find a continuous family of black holes satisfying a finite energy condition. However, for $z<2$ we find that the finite energy condition is more restrictive, and we expect only a discrete set of black hole solutions, unless some unexpected cancellations occur. For all black holes, we plot temperature $T$ as a function of horizon radius $r_0$. For $z\lessapprox 1.761$ we find that this curve develops a negative slope for certain values of $r_0$ possibly indicating a thermodynamic instability.Comment: 23 pages, 6 figures, references corrected, graphs made readable in greyscal

Holography and Unquenched Quark-Gluon Plasmas

We employ the string/gauge theory correspondence to study properties of strongly coupled quark-gluon plasmas in thermal gauge theories with a large number of colors and flavors. In particular, we analyze non-critical string duals of conformal (S)QCD, as well as ten dimensional wrapped fivebrane duals of SQCD-like theories. We study general properties of the dual plasmas, including the drag force exerted on a probe quark and the jet quenching parameter. We find that these plasma observables depend on the number of colors and flavors in the ``QCD dual''; in particular, we find that the jet quenching parameter increases linearly with N_f/N_c at leading order in the probe limit. In the ten dimensional case we find a non trivial drag coefficient but a vanishing jet quenching parameter. We comment on the relation of this result with total screening and argue that the same features are shared by all known plasmas dual to fivebranes in ten dimensions. We also construct new D5 black hole solutions with spherical horizon and show that they exhibit the same features.Comment: 30 pages. v2: Comments in section 2 and references updated, a typo fixe

Demand and unmet need for modern contraception among mothers from a Pelotas Birth Cohort

OBJECTIVE: To determine the total demand and unmet need for contraception with modern methods and their determinants among mothers participating in the 2015 Pelotas Birth Cohort. METHODS: Data from the 48-month follow-up of mothers participating in the 2015 Pelotas Birth Cohort were analyzed. Only biological mothers (aged up to 49 years) of children belonging to the 2015 Birth Cohort and who answered the 48-month questionnaire were included in the study sample. Logistic regression and respective 95% confidence intervals were used to determine associated factors. RESULTS: The study sample consisted of 3,577 biological mothers. The prevalence of use of any contraceptive and of modern contraceptives was 86.0% (95%CI: 84.8–87.1) and 84.9% (95%CI: 83.7–86.1), respectively. The prevalence of unmet need for modern contraceptives was 10.7% (95%CI: 9.7–11.7), and the total demand for contraceptives was 95.6%. The factors associated with an unmet need for modern contraception were being over 34 years of age (OR = 0.6, 95%CI: 0.5–0.8), not having a husband or partner (OR = 1.9, 95%CI: 1.4–2.6), not being the head of the household (OR = 0.6, 95%CI: 0.4–0.9), having had three or more pregnancies (OR = 1.9, 95%CI: 1.3–2.6), and having had an abortion at least once after the birth of the child participating in the cohort (OR = 1.9, 95%CI: 1.0–3.6). CONCLUSIONS: Despite the high prevalence of modern contraceptive use, one in ten women had an unmet need for modern contraception and was at risk of unplanned pregnancy

Imaging the cold molecular gas in SDSS J1148 + 5251 at z = 6.4

We present Karl G. Jansky Very Large Array (VLA) observations of the CO ($J = 2 \rightarrow 1$) line emission towards the $z = 6.419$ quasar SDSS J$114816.64+525150.3$ (J$1148+5251$). The molecular gas is found to be marginally resolved with a major axis of $0.9"$ (consistent with previous size measurements of the CO ($J = 7 \rightarrow 6$) emission). We observe tentative evidence for extended line emission towards the south west on a scale of ~$1.4"$, but this is only detected at $3.3\sigma$ significance and should be confirmed. The position of the molecular emission region is in excellent agreement with previous detections of low frequency radio continuum emission as well as [C ii] line and thermal dust continuum emission. These CO ($J = 2 \rightarrow 1$) observations provide an anchor for the low excitation part of the molecular line SED. We find no evidence for extended low excitation component, neither in the spectral line energy distribution nor the image. We fit a single kinetic gas temperature model of 50 K. We revisit the gas and dynamical masses in light of this new detection of a low order transition of CO, and confirm previous findings that there is no extended reservoir of cold molecular gas in J$1148+5251$, and that the source departs substantially from the low $z$ relationship between black hole mass and bulge mass. Hence, the characteristics of J$1148+5251$ at $z = 6.419$ are very similar to $z$~$2$ quasars, in the lack of a diffuse cold gas reservoir and kpc-size compactness of the star forming region.IIS thanks the Science & Technology Facilities Council for a studentship.This article has been accepted for publication in Monthly Notices of the Royal Astronomical Society (c): 2015 The Authors.

VIDA NA PÓS-MODERNIDADE: A INFLUÊNCIA DIGITAL E O ESVAZIAMENTO DAS INDIVIDUALIDADES :

The present study has as its object the digital influence that occurs through the internet. The objective is to investigate the behavioral changes related to the digital environment through the process of influence exerted by the online medium, its capacity for massification of people and the emptying of individualities. Methodologically, a bibliographical and documental survey and presentation of examples are used, in the light of the phenomenological epistemological paradigm. During the investigation, the inductive method is used. Of the categories, digital influence stands out as behavioral influence, in order to motivate a certain behavior or feeling of the internet user. From the results, a certain level of intervention promoted by the digital medium in individuality is identified, a catalyst for behavioral change. This level of intervention is due to a high personal valuation that Internet users attribute to the online world; by an organized action of IT service providers; by the way Internet users are treated, synthesized in the notion of mass, with no distinction of their opinions; and because this is a contemporary operation of postmodern society (or liquid society), as in this social arrangement the fluidity of values that were once considered rigid is recognized as a major guideline.El presente estudio tiene como objeto la influencia digital que se produce a través de internet. El objetivo es investigar los cambios de comportamiento relacionados con el entorno digital a través del proceso de influencia que ejerce el medio online, su capacidad de masificación de personas y de vaciamiento de individualidades.

Durante la investigación se utiliza el método inductivo. De las categorías, la influencia digital se destaca como influencia conductual, con el fin de motivar un determinado comportamiento o sentimiento del internauta. A partir de los resultados, se identifica un cierto nivel de intervención que promueve el medio digital en la individualidad, catalizador del cambio de comportamiento. Este nivel de intervención se debe a una alta valoración personal que los internautas atribuyen al mundo online; por una acción organizada de proveedores de servicios de TI; por la forma en que se trata a los internautas, sintetizada en la noción de masa, sin distinción de opiniones; y porque se trata de una operación contemporánea de la sociedad posmoderna (o sociedad líquida), pues en este arreglo social se reconoce como pauta principal la fluidez de valores que antes se consideraban rígidos.O presente estudo tem como objeto a influência digital que ocorre por meio da internet.

Impacto de la Proteína-C reactiva en el riesgo cardiovascular de adolescentes

Vários estudos sugerem que a proteína-C reativa (PCR) se correlaciona com doença arterial coronariana em adultos. Entretanto, essa associação ainda é pouco explorada em adolescentes. Avaliar a associação entre a PCR e os fatores de risco cardiovascular em adolescentes obesos. Oitenta e quatro adolescentes (12,6 ± 1,3 anos), ambos os sexos, foram distribuídos nos grupos Eutrófico (n = 28), Sobrepeso (n = 28) e Obeso (n = 28), segundo o índice de massa corpórea (IMC). A concentração de PCR (ELISA ultrassensível), o perfil lipídico e o conteúdo de anticorpos anti-LDLox (ELISA) foram determinados após jejum de 12h. Os grupos foram semelhantes quanto a idade (p = 0,13) e sexo (p = 0,83). Colesterol total, HDL-C, CT/HDL-C e LDL-C/HDL-C apresentaram diferenças significativas entre os grupos Eutrófico e Obeso. Não houve variação significativa no conteúdo de anticorpos anti-LDLox. Os valores de PCR foram diferentes entre os três grupos (p < 0,01). PCR apresentou associação significativa com IMC (β = 2,533), CB (β = 2,645) e CC (β = 2,945), CT (β = 0,006), LDL-C (β = 0,006) e anticorpos anti-LDLox (β = 0,383) e negativa entre HDL-C (β = -0,017). Os resultados indicam que a PCR se associa significativamente com marcadores de risco cardiovascular em adolescentesBACKGROUND: Several studies suggest that C-reactive protein (CRP) is associated with coronary artery disease in adults. However, this association has not been thoroughly explored in cases of adolescents. OBJECTIVE: To evaluate the association between CRP and cardiovascular risk factors in obese adolescents. METHODS: Eighty-four adolescents (12.6 ± 1.3 years) of both genders were divided into the following groups: Normal weight (n = 28), Overweight (n = 28), and Obese (n = 28), according to body mass index (BMI). CRP levels (ultrasensitive ELISA), the lipid profile, and anti-oxLDL antibody levels (ELISA) were determined after a 12-hour fast. RESULTS: The groups were similar in age (p = 0.13) and gender (p = 0.83). Total cholesterol, HDL-C, TC/HDL-C, and LDL-C/HDL-C showed significant differences between Normal weight and Obese groups. There was no significant variation in anti-oxLDL levels. CRP values were different among the three groups (p < 0.01). CRP levels showed a significant association with BMI (β = 2.533), AC (β = 2.645), WC (β = 2.945), TC (β = 0.006), LDL-C (β = 0.006), and anti-oxLDL antibodies (β = 0.383), and a negative association with HDL-C (β = -0.017).

Assisted reproductive technology: prevalence and associated factors in Southern Brazil

OBJECTIVE: To assess the prevalence of successful assisted reproductive technology and to identify the associated factors. METHODS: This population-based birth cohort study was carried out with 4,333 pregnant women expected to deliver in 2015 in the urban area of Pelotas, Southern Brazil. Use of an assisted reproductive technology procedure, type of assisted reproductive technology [in vitro fertilization or intracytoplasmic sperm injection or artificial insemination], number of embryos transferred, success of embryo transfer, number of attempts, and reported reasons for seeking assisted reproductive technology were the main outcomes measured. Use of an assisted reproductive technology procedure was analyzed according to sociodemographic, nutritional, reproductive history, and behavioral characteristics. Unadjusted and adjusted analyses were performed by logistic regression. RESULTS: Among the 4,275 newborns enrolled in the Pelotas 2015 Birth Cohort Study, 18 births (0.4%) were conceived by assisted reproductive technology. Most cases of assisted reproductive technology were by in vitro fertilization (70.6%). All cycles were performed in private clinics under direct out-of-pocket payment. Even after controlling for confounders, maternal age &gt; 35 years, nulliparity and high family monthly income were strongly associated with assisted reproductive technology. CONCLUSIONS: The use of assisted reproductive technology services was reported by only a few women in the Pelotas 2015 Birth Cohort Study. Our study highlights sociodemographic factors associated to assisted reproductive technology procedures. To better understand the patterns and barriers in overall use of assisted reproductive technology services over time, national-level trend studies in assisted reproductive technology treatments and outcomes, as well as studies exploring the characteristics of women who have sought this kind of treatment are needed in low-middle income countries
