Mainly heterosexual, bisexual, or other?: The measurement of sexual minority status and its impact on analytic sample, demographic distribution and health outcomes.

Background: Sexual orientation has been measured in a wide variety of ways which reflect both theoretical and practical considerations. However, choice of sexual orientation measure and recoding strategy can impact analytic sample, as well as demographic and health profiles, in analyses of sexual minority populations. We aimed to examine how choice of sexual orientation dimension and recoding decisions impact estimates in the sexual minority population in two population-based studies in the UK.

Etiology of hospital mortality in children living in low- and middle-income countries: a systematic review and meta-analysis.

In 2019, 80% of the 7.4 million global child deaths occurred in low- and middle-income countries (LMICs). Global and regional estimates of cause of hospital death and admission in LMIC children are needed to guide global and local priority setting and resource allocation but are currently lacking.

Limited utility of salivary mineral content in prediction of fragility fractures among postmenopausal women.

Background: Osteoporosis is a metabolic disease characterized by increased bone fragility. As it is characterized as a general skeletal disease, changes can also be seen in the stomatognathic system (edentulism, wrong fitting of dentures, etc.).

Nature and Redox Properties of Iron Sites in Zeolites Revealed by Mössbauer Spectroscopy.

Iron-containing zeolite-based catalysts play a pivotal role in environmental processes aimed at mitigating the release of harmful greenhouse gases, such as nitrous oxide (NO) and methane (CH). Despite the rich iron chemistry in zeolites, only a fraction of iron species that exhibit an open coordination sphere and possess the ability for electron transfer are responsible for activating reagents. In addition, the splitting of molecular oxygen is facilitated by bare iron cations embedded in zeolitic matrices.

OSTEOPOROSIS FROM YESTERDAY TO TODAY – A NARRATIVE REVIEW.

Despite different lifestyles, humankind has suffered from osteoporosis for thousands of years. A literature review concerning the history of osteoporosis in the following databases: Index Medicus, Medline, PubMed, and PMC Citations was done. In the final analysis, 18 review articles and 31 original papers were included.

Organization of Cooperating Aluminum Pairs in Ferrierite Evidenced by Luminescence Quenching.

We show that four cooperating Al atoms located at the two neighboring six-membered (6-MR) rings in the ferrierite framework can be readily discerned by luminescence studies. Thus, luminescent Zn(II) cations accommodated by one aluminum pair of the 6-MR ring can be effectively quenched by neighboring Co(II) ions stabilized by the second ring. Quenching occurs via the energy transfer mechanism and allows estimation of the critical radius of Zn(II)-Co(II) interactions.

The Impact of Environmental and Genetic Factors on Bone Quality in Monozygotic and Dizygotic Twins.

The purpose of the research was to assess the genetic and environmental influences on bone properties. One hundred thirty-two pairs of twins (99/33 monozygotic/dizygotic) underwent anthropometric measurements and phalangeal quantitative ultrasound (DBM Sonic 1200, Igea, Italy) measuring the amplitude speed of sound (AD-SoS, m/s). The mean age was 16.

IL-12p40 promotes secondary damage and functional impairment after spinal cord contusional injury.

Secondary damage obstructs functional recovery for individuals who have sustained a spinal cord injury (SCI). Two processes significantly contributing to tissue damage after trauma are spinal cord hemorrhage and inflammation: more specifically, the recruitment and activation of immune cells, frequently driven by pro-inflammatory factors. Cytokines are inflammatory mediators capable of modulating the immune response.

Ethnic and Sexual Identity-Related Inequalities in Adolescent Health and Well-Being in a National Population-Based Study.

This study employed an intersectional framework to examine impact of inequalities related to sexual minority (SM) and ethnic minority (EM) identities in risk for health, well-being, and health-related behaviors in a nationally representative sample. Participants included 9789 (51% female) adolescents aged 17 years from the U.K.

Higher education and better knowledge of osteoporosis improve bone health in Polish postmenopausal women.

Introduction: The aim of the study was to establish the influence of knowledge of osteoporosis and educational level on bone health.

Formation and local structure of framework Al Lewis sites in beta zeolites.

Framework Al Lewis sites represent a substantial portion of active sites in H-BEA zeolite catalysts activated at low temperatures. We studied their nature by Al WURST-QCPMG nuclear magnetic resonance (NMR) and proposed a plausible mechanism of their formation based on periodic density functional theory calculations constrained by H MAS, Al WURST-QCPMG, and Si MAS NMR experiments and FTIR measurements. Our results show that the electron-pair acceptor of Al Lewis sites corresponds to an Al atom tricoordinated to the zeolite framework, which adsorbs a water molecule.

Global PARITY: Study Design for a Multi-Centered, International Point Prevalence Study to Estimate the Burden of Pediatric Acute Critical Illness in Resource-Limited Settings.

Background: The burden of pediatric critical illness and resource utilization by children with critical illness in resource limited settings (RLS) are largely unknown. Without specific data that captures key aspects of critical illness, disease presentation, and resource utilization for pediatric populations in RLS, development of a contextual framework for appropriate, evidence-based interventions to guide allocation of limited but available resources is challenging. We present this methods paper which describes our efforts to determine the prevalence, etiology, hospital outcomes, and resource utilization associated with pediatric acute, critical illness in RLS globally.

Analysis of NH -TPD Profiles for CuSSZ-13 SCR Catalyst of Controlled Al Distribution - Complexity Resolved by First Principles Thermodynamics of NH Desorption, IR and EPR Insight into Cu Speciation*.

NH temperature-programmed desorption (NH -TPD) is frequently used for probing the nature of the active sites in CuSSZ-13 zeolite for selective catalytic reduction (SCR) of NO . Herein, we propose an interpretation of NH -TPD results, which takes into account the temperature-induced dynamics of NH interaction with the active centers. It is based on a comprehensive DFT/GGA+D and first-principles thermodynamic (FPT) modeling of NH adsorption on single Cu , Cu , [CuOH] centers, dimeric [Cu-O-Cu] , [Cu-O -Cu] species, segregated CuO nanocrystals and Brønsted acid sites (BAS).

Exposure to televised political campaign advertisements aired in the United States 2015-2016 election cycle and psychological distress.

Context: Prior research suggests the potential for political campaign advertisements to increase psychological distress among viewers. The current study tests relationships between estimated exposure to campaign advertising and the odds of respondents reporting that a doctor told them they have anxiety, depression, insomnia, or (as a negative control) cancer.

Methods: A secondary analysis of U.

Dioxygen splitting at room temperature over distant binuclear transition metal centers in zeolites for direct oxidation of methane to methanol.

Here we demonstrate for the first time the splitting of dioxygen at RT over distant binuclear transition metal (M = Ni, Mn, and Co) centers stabilized in ferrierite zeolite. Cleaved dioxygen directly oxidized methane to methanol, which can be released without the aid of an effluent to the gas phase at RT.

Five-year fracture risk assessment in postmenopausal women, using both the POL-RISK calculator and the Garvan nomogram: the Silesia Osteo Active Study.

Unlabelled: The study project was designed to assess the concordance of clinical results in the assessment of 5-year fracture risk of any fracture, carried out by two methods: the Garvan algorithm and the POL-RISK model. The study group included 389 postmenopausal women of Caucasian race. The concordance of results, obtained by those two models, turned out to be moderate, and the threshold for high fracture risk group was 11% in the POL-RISK model.
