An examination of the barriers to and benefits from collaborative couple contraceptive use in Rwanda.

Background: Supportive male involvement is strongly correlated with contraceptive use. In Rwanda, where the contraceptive prevalence rate among married women increased from 17 to 52% from 2005 to 2010, and stagnated at 53% in 2015, understanding the role of male partners in collaborative couple contraceptive use can help inform programs designed to further increase the use of contraception in Rwanda.

Methods: This study utilized qualitative methods in 2018, specifically 32 in-depth interviewers with mostly current users of modern contraceptive methods and eight focus group discussions with family planning providers-both family planning nurses and community health workers (CHWs).

"… the way we welcome them is how we will lead them to love family planning.": family planning providers in Rwanda foster compassionate relationships with clients despite workplace challenges.

Background: Rwanda has markedly increased the nation's contraceptive use in a short period of time, tripling contraceptive prevalence in just 5 years between 2005 and 2010. An integral aspect of family planning programs is the interactions between family planning providers and clients. This study aims to understand the client-provider relationship in the Rwandan family planning program and to also examine barriers to those relationships.

Physiological sensation word usage in social anxiety disorder with and without comorbid depression.

Background & Objectives: Social anxiety disorder (SAD) is characterized by a fear of showing anxiety symptoms, which may manifest in greater physiological sensation (PS) word usage, especially when describing their anxious experiences. However, the role of comorbid major depressive disorder (MDD) is unknown. Given blunted physiological arousal in MDD, the SAD only group (SAD) may use more PS words than the comorbid (COM) group with SAD and MDD when discussing anxious memories.

How much and how fast: Alcohol consumption patterns, drinking-episode affect, and next-day consequences in the daily life of underage heavy drinkers.

Background: Understanding how alcohol consumption patterns are associated with negative and positive outcomes can inform efforts to reduce negative consequences through modification of those patterns. This is important in underage drinkers, many of whom drink heavily despite negative consequences. Most work has focused on the amount of alcohol consumed, but amount provides limited information about consumption patterns compared to rate of consumption, or how fast individuals drink.

After the publication of the original article [1], we were notified that one of the corresponding author's name and her related institution were wrongly spelled.

Dataset of plant composition change over seven years at the Zumwalt Prairie Preserve, Oregon, USA.

The data and analyses presented here were collected at the Zumwalt Prairie Preserve (ZPP), northeastern Oregon. Vegetation composition was measured within 124 (1-ha) plots using the line point intercept method [1,2]. These data include vascular plant species abundance matrices at two different time periods, seven years apart (2008/2009 & 2015/2016); boxplots of species abundance (cover and frequency) change over time; Non-parametric Multiplicative Regression (NPMR) estimated abundance of , an invading non-native annual grass, in geographic and ordination (Non-metric Multidimensional Scaling ordination; NMS) space over time.

Testing a model of body image in the bariatric surgery patient.

Purpose: The purpose was to test a published model of body image in the bariatric surgery patient in the clinical office setting.

Background: A model was created based on clinical observations during field work and the literature. It focuses on five concepts of body image: body attitude, body checking, appearance orientation, perceived body size, and perceived body space.

Membranes Composed of Lipopeptides and Liponucleobases Inspired Protolife Evolution.

Amino acids and peptides have been demonstrated to form lipoamino acids and lipopeptides under presumed prebiotic conditions, and readily form liposomes. Of the common nucleobases, adenine forms a liponucleobase even below 100 °C. Adenine as well as other nucleobases can also be derivatized with ethylene carbonate (and likely other similar compounds) onto which fatty acids can be attached.

Sex differences in 10-year ischemic cardiovascular disease risk prediction in Chinese patients with prediabetes and type 2 diabetes.

Background: Cardiovascular disease has become a serious public health problem in recent years in China. The aim of the study was to examine sex differences in cardiovascular risk factors and 10-year ischemic cardiovascular disease (ICVD) risk in Chinese patients with prediabetes (PreDM) and type 2 diabetes mellitus (T2DM).

Methods: This was a multi-site retrospective case-control study conducted from April-November 2016 using an electronic medical record database, involving 217 PreDM and 900 T2DM patients admitted to endocrinology units in four hospitals in China.

Assessing the blood meal hosts of Culex quinquefasciatus and Aedes taeniorhynchus in Isla Santa Cruz, Galápagos.

Background: Blood meal host selection by mosquito vectors is an important component in understanding disease dynamics of pathogens that threaten endemic fauna in isolated islands such as Galápagos. Research on the feeding behavior of mosquitoes can provide clues to the hosts and vectors involved in disease transmission. This information is particularly critical for endemic wildlife fauna in island systems that have evolved without resistance to novel diseases such as avian malaria.

Dataset of plant community composition in the Zumwalt Prairie Preserve, Oregon, USA.

These data support the research article: "Non-native species threaten the biotic integrity of the largest remnant Pacific Northwest Bunchgrass prairie in the United States" Endress et al. (2019) [1].The data were collected at the Zumwalt Prairie Preserve (Zumwalt), northeastern Oregon, USA, and include vascular plant species abundance matrices from 123 plots sampled in 2008 and 2009 and the estimated abundance of dominant species in community space.

Changes in health insurance coverage and health care access as teens with disabilities transition to adulthood.

Background: Pre-ACA, less than 6% of children with disabilities were uninsured, compared with more than 42% of young adults with disabilities ages 19-25. Individuals with disabilities face greater barriers to health care access upon transition into adulthood.

Objectives: We examined whether the ACA dependent coverage provision and Medicaid expansion improved the transition from pediatric to adult healthcare systems by reducing the gap in insurance coverage and access to care between teens and young adults with disabilities.

Organization and regulation of cyanobacterial nif gene clusters: implications for nitrogenase expression in plant cells.

For over 50 years scientists have considered the possibility of engineering a plant with nitrogen fixation capability, freeing farmers from their dependence on nitrogen fertilizers. With the development of the tools of synthetic biology, more progress has been made toward this goal in the last 5 years than in the previous five decades. Most of the effort has focused on nitrogenase genes from Klebsiella oxytoca, which has complex gene regulation.

Heritability and genetic associations of triglyceride and HDL-C levels using pedigree-based and empirical kinships.

The heritability of a phenotype is an estimation of the percent of variance in that phenotype that is attributable to additive genetic factors. Heritability is optimally estimated in family-based sample populations. Traditionally, this involves use of a pedigree-based kinship coefficient generated from the collected genealogical relationships between family members.

Haemosporidian parasite community in migrating bobolinks on the Galapagos Islands.

Bobolinks () migrate from their breeding grounds in North America to their wintering grounds in South America during the fall each year. A small number of Bobolinks stop temporarily in Galapagos, and potentially carry parasites. On the North American breeding grounds, Bobolinks carry a least two of the four lineages recently detected in resident Galapagos birds.

The Role of Disease Conviction: Exploring Its Effects on Chest Pain and Anxiety-Related Models of Non-cardiac Chest Pain.

The aim of this study was to investigate the role of disease conviction in the chest pain and life interference of patients with non-cardiac chest pain (NCCP), after controlling for anxiety sensitivity and body vigilance. While all three psychological constructs are theoretically implicated and empirically associated with the experience of NCCP, no research has examined the influence of disease conviction in the context of other relevant constructs. The sample included 229 participants with NCCP who were recruited after a medical evaluation failed to elicit an organic explanation for their chest pain.

Conceptualization of body image in the bariatric surgery patient.

Bariatric (weight loss) surgery is more popular than ever. The American Society for Metabolic and Bariatric Surgery in 2016 reported that 216,000 bariatric procedures were performed in the United States. Bariatric surgery has major physiological benefits; its use is expected to increase globally.

Landscape genomics: natural selection drives the evolution of mitogenome in penguins.

Background: Mitochondria play a key role in the balance of energy and heat production, and therefore the mitochondrial genome is under natural selection by environmental temperature and food availability, since starvation can generate more efficient coupling of energy production. However, selection over mitochondrial DNA (mtDNA) genes has usually been evaluated at the population level. We sequenced by NGS 12 mitogenomes and with four published genomes, assessed genetic variation in ten penguin species distributed from the equator to Antarctica.

Nutritional supplement practices of professional Ugandan athletes: a cross-sectional study.

Background: The use of nutritional supplements (NS) places athletes at great risk for inadvertent doping. Due to the paucity of data on supplement use, this study aimed to determine the proportion of Ugandan athletes using nutritional supplements and to investigate the athletes' motivation to use these supplements.

Methods: A cross-sectional study was conducted in which an interviewer-administered questionnaire was used to collect data from 359 professional athletes participating in individual (boxing, cycling, athletics) and team (basketball, rugby, football, netball, and volleyball) sports.

Intramolecular glycosylation.

Carbohydrate oligomers remain challenging targets for chemists due to the requirement for elaborate protecting and leaving group manipulations, functionalization, tedious purification, and sophisticated characterization. Achieving high stereocontrol in glycosylation reactions is arguably the major hurdle that chemists experience. This review article overviews methods for intramolecular glycosylation reactions wherein the facial stereoselectivity is achieved by tethering of the glycosyl donor and acceptor counterparts.

Interactions Between Carnivores in Madagascar and the Risk of Disease Transmission.

Introduced carnivores exert considerable pressure on native predators through predation, competition and disease transmission. Recent research shows that exotic carnivores negatively affect the distribution and abundance of the native and endangered carnivores of Madagascar. In this study, we provide information about the frequency and distribution of interactions between exotic (dogs and cats) and native carnivores (Eupleridae) in the Betampona Natural Reserve (BNR), Madagascar, using noninvasive camera trap surveys.

Data and analyses of woody restoration planting survival and growth as a function of wild ungulate herbivory.

These data and analyses support the research article "Wild ungulate herbivory suppresses deciduous woody plant establishment following salmonid stream restoration" Averett et al. (2017) [1]. The data and analyses presented here include: (1) planting density, survival and growth (two years post restoration) of riparian plantings along an ~11 km stream reach in northeastern Oregon as a function of herbivory treatment (protected/not protected from wild ungulate herbivory), habitat type, and planting species; and (2) abundance and height distributions of naturally occurring deciduous woody species along the restored stream reach two years post restoration.

From Galapagos doves to passerines: Spillover of .

, a haemosporidian parasite thought to be specific to columbiform birds, was detected in passeriform birds on Santiago Island in the Galapagos archipelago. We surveyed birds along an altitudinal gradient on the islands of Santa Cruz, Isabela and Santiago between June 2013 and July 2015. Molecular screening of 2254 individuals from 25 species of endemic and introduced birds revealed clusters of passerine birds positive for on Santiago Island that coincide with captures of Galapagos doves at sampled sites.

Correlates of pericardial adipose tissue volume using multidetector CT scanning in cardiac patients in China.

Background: Pericardial adipose tissue (PAT) is an emerging cardiovascular risk factor, yet much less is understood about PAT volume in Chinese adults, especially in relation to physical activity. The study explores associations between demographic and clinical variables and PAT volume, using multidetector computed tomography (MDCT) scanning in China. We also examined the relationship between PAT volume and coronary artery disease (CAD).

Temporal and demographic blood parasite dynamics in two free-ranging neotropical primates.

Parasite-host relationships are influenced by several factors intrinsic to hosts, such as social standing, group membership, sex, and age. However, in wild populations, temporal variation in parasite distributions and concomitant infections can alter these patterns. We used microscropy and molecular methods to screen for naturally occurring haemoparasitic infections in two Neotropical primate host populations, the saddleback () and emperor () tamarin, in the lowland tropical rainforests of southeastern Peru.
