Using Test Question Templates to teach physiology core concepts.

The past ∼15 years have seen increasing interest in defining disciplinary core concepts. Within the field of physiology, Michael, McFarland, Modell, and colleagues have published studies that defined physiology core concepts and have elaborated many of these as detailed conceptual frameworks. With such helpful definitions now in place, attention is turning to the related issue of how to maximize student understanding of the core concepts by linking these "big ideas" to concrete student-facing resources for active learning and assessment.

Fast and automated protein-DNA/RNA macromolecular complex modeling from cryo-EM maps.

Cryo-electron microscopy (cryo-EM) allows a macromolecular structure such as protein-DNA/RNA complexes to be reconstructed in a three-dimensional coulomb potential map. The structural information of these macromolecular complexes forms the foundation for understanding the molecular mechanism including many human diseases. However, the model building of large macromolecular complexes is often difficult and time-consuming.

Smart de novo Macromolecular Structure Modeling from Cryo-EM Maps.

The study of macromolecular structures has expanded our understanding of the amazing cell machinery and such knowledge has changed how the pharmaceutical industry develops new vaccines in recent years. Traditionally, X-ray crystallography has been the main method for structure determination, however, cryogenic electron microscopy (cryo-EM) has increasingly become more popular due to recent advancements in hardware and software. The number of cryo-EM maps deposited in the EMDataResource (formerly EMDatabase) since 2002 has been dramatically increasing and it continues to do so.

Leveraging network analysis to determine sex differences in factors associated with frailty among older adults living alone.

Background: Frailty is a complex geriatric syndrome typically characterized by multiple underlying etiological factors. We determined the contributing factors, by sex, using a network analysis.

Methods: The study sample consisted of a cross-sectional cohort of community-dwelling older adults aged ≥ 65 years living alone in a Korean city (N = 1,037).

The Role of Psychological Factors in Chronic Pain Treatment Outcomes in the Military.

Purpose: Chronic pain treatment in the military includes complementary and integrative health (CIH) therapies that may affect psychological factors such as pain catastrophizing, chronic pain acceptance, pain self-efficacy, and patient activation. The unique roles that psychosocial factors play in how CIH approaches reduce pain are not clear. This study examined if a holistic pain management program improved pain outcomes through psychological mediators in service members with chronic pain.

Understanding changes in mental health symptoms from young-old to old-old adults by sex using multiple-group latent transition analysis.

Older adults are classified into three homogeneous groups: young-old (age 65-74), old-old (age 75-84), and oldest-old (age 85 and over). Mental health symptoms are likely to change over time, especially when older adults transition from one age group to another. Yet, little is known on changes in mental health symptoms as they transition to another age group, and if these changes differ by sex.

Birth includes us: Development of a community-led survey to capture experiences of pregnancy care among LGBTQ2S+ families.

Background: Limited research captures the intersectional and nuanced experiences of lesbian, gay, bisexual, transgender, queer, two-spirit, and other sexual and gender-minoritized (LGBTQ2S+) people when accessing perinatal care services, including care for pregnancy, birth, abortion, and/or pregnancy loss.

Methods: We describe the participatory research methods used to develop the Birth Includes Us survey, an online survey study to capture experiences of respectful perinatal care for LGBTQ2S+ individuals. From 2019 to 2021, our research team in collaboration with a multi-stakeholder Community Steering Council identified, adapted, and/or designed survey items which were reviewed and then content validated by community members with lived experience.

Protocol for the pilot quasi-experimental controlled trial of a gender-responsive implementation strategy with providers to improve HIV outcomes in Uganda.

Background: Antiretroviral treatment (ART) is the most effective clinical intervention for reducing morbidity and mortality among persons living with HIV. However, in Uganda, there are disparities between men and women in viral load suppression and related HIV care engagement outcomes, which suggests problems with the implementation of ART. Gender norms are a known driver of HIV disparities in sub-Saharan Africa, and patient-provider relationships are a key factor in HIV care engagement; therefore, the role of gender norms is important to consider in interventions to achieve the equitable provision of treatment and the quality of ART counseling.

The Impact of Collaborative Online International Learning on Intercultural Sensitivity Among Nursing Students in the United States and Japan.

Collaborative online international learning (COIL) is a curricular approach that allows students to collaborate across cultures using various communication technologies. Little is known about the influence of COIL on intercultural sensitivity, a key competency for nursing students to better serve increasingly diverse patient populations. We implemented COIL in undergraduate nursing courses in the United States and Japan and examined its impact on intercultural sensitivity using the Intercultural Sensitivity Scale (ISS) as a pretest and posttest.

Superiorization-inspired unrolled SART algorithm with U-Net generated perturbations for sparse-view and limited-angle CT reconstruction.

Unrolled algorithms are a promising approach for reconstruction of CT images in challenging scenarios, such as low-dose, sparse-view and limited-angle imaging. In an unrolled algorithm, a fixed number of iterations of a reconstruction method are unrolled into multiple layers of a neural network, and interspersed with trainable layers. The entire network is then trained end-to-end in a supervised fashion, to learn an appropriate regularizer from training data.

Hypnosis and relaxation interventions for chronic pain management in cancer survivors: a randomized controlled trial.

Purpose: Nonpharmacological interventions such as hypnosis show promising evidence for the self-management of pain and pain-related sequelae among cancer survivors. The purpose of this study was to evaluate the efficacy of a 4-week recorded hypnosis intervention in reducing pain intensity compared to a recorded relaxation intervention in cancer survivors with chronic pain.

Methods: Adult cancer survivors were randomly assigned to listen to hypnosis (n = 55) or relaxation recordings (n = 54) daily for 28 days.

Impact of Dementia on Long-Term Hip Fracture Surgery Outcomes: An Electronic Health Record Analysis.

Objective: Older adults with dementia are at higher risk for sustaining hip fracture and their long-term health outcomes after surgery are usually worse than those without dementia. Widespread adoption of electronic health records (EHRs) may allow hospitals to better monitor long-term health outcomes in patients with dementia after hospitalization. This study aimed to (1) estimate how dementia influences discharge location, mortality, and readmission 180 days and 1 year after hip fracture surgery in older adults, and (2) demonstrate the feasibility of using selection-bias reduced EHR data for research and long-term health outcomes monitoring.

Healthcare graduate students' perceived control and preventive behavior for COVID-19 in Japan and the United States: A cross-sectional study.

Background: Both individual and policy level perceived control are known to be positively related to preventive behavior, and both may differ among healthcare graduate students with different cultural backgrounds. This study compared the preventive health behavior and perceived control among domestic and international healthcare graduate students in Japan and the United States during the COVID-19 pandemic, and analyzed factors associated with preventive health behavior and perceived control.

Methods: The study used a self-administered online survey, conducted at two universities in Japan and one university in the United States.

Struggling, helping and adapting: Crowdfunding motivations and outcomes during the early US COVID-19 pandemic.

During the early months of COVID-19, many people in the US turned to charitable crowdfunding to seek and provide assistance. Little is known about the needs, hopes or experiences that motivated US pandemic crowdfunding and how these were correlated with campaign success. This study uses a mixed-methods data analysis of a randomised cluster sample of 919 US GoFundMe campaigns during the first 7 months of the pandemic.

Using the Black Carbon Particle Mixing State to Characterize the Lifecycle of Biomass Burning Aerosols.

The lifecycle of black carbon (BC)-containing particles from biomass burns is examined using aircraft and surface observations of the BC mixing state for plume ages from ∼15 min to 10 days. Because BC is nonvolatile and chemically inert, changes in the mixing state of BC-containing particles are driven solely by changes in particle coating, which is mainly secondary organic aerosol (SOA). The coating mass initially increases rapidly ( = 0.

Factors related to mental health effect among nursing students in Japan and the United States during the coronavirus pandemic: A cross-sectional study.

In the context of mental health, university students have been considered a vulnerable population. However, limited studies have underscored the association between preventive health behaviour levels and mental health effects among nursing students. The current cross-sectional study provides a comparative analysis of the impact of mental health factors on nursing students in Japan and the United States (US) in the context of the coronavirus disease 2019 (COVID-19) pandemic.

Genetic associations with resilience to potentially traumatic events and vantage sensitivity to social support.

Introduction: Stress responses and mental health outcomes greatly vary when individuals are exposed to potentially traumatic events (PTEs). The Differential Susceptibility Model (DSM) (Pluess, 2015) suggests individual differences in stress responses are influenced by gene-environment interactions, with genes conferring reactivity. While individuals can be resilient (or vulnerable) to PTEs, they can also have vantage sensitivity (or resistance) to social support.

Structure of OmcZ filaments suggests extracellular cytochrome polymers evolved independently multiple times.

While early genetic and low-resolution structural observations suggested that extracellular conductive filaments on metal-reducing organisms such as were composed of type IV pili, it has now been established that bacterial -type cytochromes can polymerize to form extracellular filaments capable of long-range electron transport. Atomic structures exist for two such cytochrome filaments, formed from the hexaheme cytochrome OmcS and the tetraheme cytochrome OmcE. Due to the highly conserved heme packing within the central OmcS and OmcE cores, and shared pattern of heme coordination between subunits, it has been suggested that these polymers have a common origin.

NO and O Trends at U.S. Non-Attainment Areas for 1995-2020: Influence of COVID-19 Reductions and Wildland Fires on Policy-Relevant Concentrations.

We analyzed NO and O data from 32 U.S. non-attainment areas (NAAs) for 1995-2020.

Machine learning-based predictive modeling of depression in hypertensive populations.

We aimed to develop prediction models for depression among U.S. adults with hypertension using various machine learning (ML) approaches.

Cryo-EM structure of an extracellular Geobacter OmcE cytochrome filament reveals tetrahaem packing.

Electrically conductive appendages from the anaerobic bacterium Geobacter sulfurreducens were first observed two decades ago, with genetic and biochemical data suggesting that conductive fibres were type IV pili. Recently, an extracellular conductive filament of G. sulfurreducens was found to contain polymerized c-type cytochrome OmcS subunits, not pilin subunits.
