Non-use of primary care routine consultations for individuals with hypertension
The objectives of this study were to identify, among individuals with hypertension, sociodemographic factors associated with non-use of routine medical appointments available in primary care and check if non-use of consultations interferes with noncompliance with pharmacotherapy, uncontrolled blood pressure and hospitalization. This is a cross-sectional study with random and stratified sampling. A total of 422 individuals living in the city of Maringá, Paraná, were interviewed. There were crude and adjusted analyses using logistic regression, estimating odds ratios and 95% confidence intervals. It was found that, in the six months preceding the interview, 47 (11.1%) individuals did not use routine appointments. Being male, nonwhite and using only public health services were associated with non-use of consultations. Most of those who did not use consultations also failed to comply with pharmacotherapy and presented dysregulated blood pressure. Healthcare professionals need to develop strategies in order to increase attendance of hypertensive individuals to medical appointments, giving priority to population groups of men, nonwhite individuals and those who use public health services. Greater use of consultations can assist in blood pressure control and reduce complications
QCD Corrections to QED Vacuum Polarization
We compute QCD corrections to QED calculations for vacuum polarization in
background magnetic fields. Formally, the diagram for virtual loops
is identical to the one for virtual loops. However due to
confinement, or to the growth of as decreases, a direct
calculation of the diagram is not allowed. At large we consider the
virtual diagram, in the intermediate region we discuss the role of
the contribution of quark condensates \left and at the
low-energy limit we consider the , as well as charged pion
loops. Although these effects seem to be out of the measurement accuracy of
photon-photon laboratory experiments they may be relevant for -ray
burst propagation. In particular, for emissions from the center of the galaxy
(8.5 kpc), we show that the mixing between the neutral pseudo-scalar pion
and photons renders a deviation from the power-law spectrum in the
range. As for scalar quark condensates \left and
virtual loops are relevant only for very high radiation density
and very strong magnetic fields of order .Comment: 15 pages, 4 figures; Final versio
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
