After multivariate analysis, social capital - in its structural component - was associated with functional disability. Older adults who were dissatisfied with the neighborhood had a higher risk of developing functional disability for IADL (HR = 2.36; 95%CI 1.31-4.24), in relation to their counterparts. This study results suggest that functional disability is associated with aspects other than health, evidencing the need for the development of policies and interventions that support aspects related to the physical and social environment in which older adults live.The objective was to estimate the direct medical cost of pregnancy care attributable to the failure of Mexico's teenage pregnancy prevention policy. From the provider's perspective, this economic study estimated the mean cost of prenatal care, childbirth, puerperium, abortion and complications. To quantify the costs attributable to policy failure, three scenarios were constructed (a) total number of pregnancies; (b) number of pregnancies above the target; (c) number of unwanted pregnancies. The cost of providing contraceptive methods was also estimated and the characteristics of pregnant adolescents were described. Of the adolescents (n = 5,477,027), 30.2% were sexually active; 46.8% used contraception; 44.1% had become pregnant and 9.1% had an abortion. Most pregnant women (65%) attended secondary school or under; 30% dropped out of school; 72.5% lived with a partner; 72.3% had complications. The mean cost of pregnancy care was estimated at USD 2,210.55 and the mean cost of providing contraceptives at USD 64.95. The total cost of policy failure was estimated for each scenario (in millions) (a) USD 1,614.39, (b) USD 876.61 and (c) USD 171.50, respectively; whereas the annual cost of providing contraceptives in each scenario was estimated in (a) USD 47.43, (b) USD 25.76 and (c) USD 5.04. The failure of the policy is expressed in the high frequency of pregnancy in low-income adolescents and in high costs for the health system. The provision of contraceptives is 34 times cheaper than pregnancy care and could, together with improved living conditions, contribute to reduce the frequency of adolescent pregnancies.This study aims to analyze the association between perceived characteristics of the neighborhood environment and changes in leisure-time physical activity in Brazilian older adults. Longitudinal analysis was performed considering a population-based study carried out in 2009/2010 with follow-up in 2013/2014. Changes in leisure-time physical activity, obtained with the International Physical Activity Questionnaire during both waves, were associated with data of environment perception with the Neighborhood Environment Walkability Scale - Abbreviated (baseline only) performing multinomial logistic regression. In total, 1,162 older adults (65.2% women, mean age = 73.7 years) participated. Older adults who perceived flat streets, bicycle paths, and high flow of vehicles in the neighborhood were more likely to remain active in leisure time walking. Those who noticed the presence of flat streets also had a greater chance of becoming active than those who did not notice it. Older adults who perceived bicycle paths and sports events were more likely to maintain moderate and vigorous physical activity during leisure time. Furthermore, older adults who noticed parks and squares close to their residence were 0.49 times less likely to become insufficiently active. Brazilian older adults are more active in neighborhoods with more favorable attributes regarding leisure-time physical activity.We aimed to evaluate the psychometric properties of the Brazilian version of the Patient Health Questionnaire (PHQ-8). A study with a sample of 4,170 individuals (≥ 15 years old) from the urban area. Conglomerate sampling was adopted in two stages (census sectors and streets), with weighting of estimates by sample weights. A structured questionnaire with sociodemographic data, the PHQ - the modules for depression, generalized anxiety disorder and panic disorder - and the Self-Reporting Questionnaire (SRQ-20) were used. In the evaluation of the PHQ-8, we verified the construct validity by analyzing the dimensional structure, convergent validity and internal consistency. We found a linear disorder without losses to maintain the four response categories. The factor analysis found unidimensionality of the depression construct, with strong factor loads, low residual variances, low residual correlation between items, good fit of the model, internal consistency and satisfactory convergent factorial validity (high loads and correlations with other tests/scales of similar constructs). The PHQ-8 has a one-dimensional structure with evidence of good validity and reliability, being suitable for use in the Brazilian population.Ambrosia beetles (Coleoptera Curculionidae, Scolytinae) and Phytophthora root rot (Peronosporales Peronosporaceae) cause significant damage to the ornamental industry in the United States. In this study, mefenoxam (fungicide), permethrin (insecticide), and charcoal + kaolin were used in different combinations with Phytophthora cinnamomi (Rands Peronosporales Peronosporaceae) inoculated and noninoculated plants to optimize the management of ambrosia beetles and Phytophthora root rot. Treatment applications were performed in two trials on 1 (mefenoxam, drench), 18 (P. cinnamomi inoculation), or 19 (permethrin, spray) days before instigating flood stress or 2 d after flood stress (charcoal + kaolin, spray), respectively. Flooding was maintained for 21 d. this website Ambrosia beetle attacks and plant growth data were recorded. Tree roots were rated at study end for disease severity and root samples were plated on PARPH-V8 medium to determine the percentage of pathogen recovery. In both trials, the combination of mefenoxam + permethrin treatment had reduced disease severity and ambrosia beetle attacks compared to the inoculated controls. Permethrin-treated trees had shorter galleries compared to controls in trial 1 and no gallery formation in trial 2. In both trials, no differences were observed among the treatments in numbers of galleries with eggs and adults, but mefenoxam + charcoal + kaolin had significantly fewer galleries with larvae among the noninoculated trees compared with the respective control in trial 1. Overall, treatments containing combinations of mefenoxam + permethrin had reduced disease severity and ambrosia beetle attacks.Ratiometric sensors are self-referencing constructs that are functional in cells and tissues, and the read-out is independent of sensor concentration. One strategy for ratiometric sensing is to utilize two-color emission, where one component possesses analyte-dependent emission and the other is independent of analyte concentration, serving as an internal standard. In this way, the intensity ratio of the two components is a quantitative measure of the analyte. In this study, protein-based ratiometric oxygen sensors are prepared using the heme nitric oxide/oxygen-binding protein (H-NOX) from the thermophilic bacterium Caldanaerobacter subterraneus. The native heme cofactor is replaced with a Pd(II) or Pt(II) porphyrin as the oxygen-responsive phosphor. Mutagenesis is performed to incorporate a cysteine residue on the protein surface for thiol/maleimide coupling of the oxygen-insensitive dye, which serves as a Förster resonance energy transfer (FRET) donor for the porphyrin. While both Pd(II)- and Pt(II)-based sensors are responsive over biologically relevant ranges, the Pd sensor exhibits greater sensitivity at lower oxygen concentrations. Together, these sensors represent a new class of protein-based ratiometric oxygen sensors, and the modular platform allows the oxygen sensitivity to be tailored for a specific application. This proof-of-principle study has identified the key considerations and optimal methodologies to develop and subsequently refine protein-based ratiometric oxygen sensors.

Describe the epidemiology and characteristics of patients with a history of mental illness undergoing otolaryngologic procedures.

A retrospective cross-sectional analysis utilizing the Nationwide Readmissions Database, 2010 to 2015. The study sample included adult (≥18 years) patients undergoing otolaryngologic procedures.

A total of 146 182 patients were included, 18.3% with mental illness history. The prevalence of patients who required otolaryngologic surgeries with history of mental illness increased significantly from 14.9% in 2010 to 25.0% in 2015 (

 < .001). Mental illness diagnoses included depression (6.9%), anxiety (5.8%), alcohol dependence (4.2%), substance dependence (2.9%), bipolar disorder (1.4%), memory disorders (1.2%), delusional disorders (0.6%), self-harm (0.1%). Patients with a history of mental illness were more likely to be <65 years, female, and have multiple comorbidities (

 < .05 each). Patients with history of mental illness had a higher risk of complications [OR1.59, 95% CI1.50,1.69,

 < .001].

Patients with a history of mental illness are increasingly encountered in otolaryngology service. This study provides an epidemiological perspective that warrants increasing clinical investigation of this subpopulation.

Using a network approach to mentoring, this program aims to increase the pipeline of underrepresented minority (URM) scientists studying Alzheimer's disease (AD) disparities. Six mentors and five scientists participated in interviews. Thematic analysis identified recurring themes; transcripts of mentors and scientists were compared. Most common thematic categories identified by mentors included experience interacting with scientists, goals as a mentor, recruitment of underrepresented minorities, scientists' challenges, and programmatic qualities. The most mentioned categories by scientists were challenges, seminars, working with mentors, career development, and project experience. The CCADMR will use findings to enhance the experience and training methods for future grant years. Results can benefit other training programs focused on aging and AD.Ferrofluids (FFs) can adapt their shape to a magnetic field. However, they cannot maintain their shape when the magnetic field is removed. Here, with a magneto-responsive and reconfigurable interfacial self-assembly (MRRIS) process, we show that FFs can be structured by a magnetic field and maintain their shape, like solids, after removing the magnetic field. The competing self-assembly of magnetic and nonmagnetic nanoparticles at the liquid interface endow FFs with both reconfigurability and structural stability. By manipulating the external magnetic field, we show that it is possible to "write" and "erase" the shape of the FFs remotely and repeatedly. To gain an in-depth understanding of the effect of MRRIS on the structure of FFs, we systematically study the shape variation of these liquids under both the static and dynamic magnetic fields. Our study provides a simple yet novel way of manipulating FFs and opens opportunities for the fabrication of all-liquid devices.
