What impact does widening participation to medicine have on the medical workforce in the UK: a scoping review.

Purpose: Widening participation in medicine refers to the recruitment policy of encouraging those who are traditionally under-represented in medical school. Whilst research in the UK has investigated the processes around improving participation through recruitment and selection to medical schools, there is less focus around the period after medical school and how students from widening participation backgrounds fare in the workforce.

Methods: This study employed scoping review methodology to collate, map and summarise research in the field.

The Bering Strait was flooded 10,000 years before the Last Glacial Maximum.

The cyclic growth and decay of continental ice sheets can be reconstructed from the history of global sea level. Sea level is relatively well constrained for the Last Glacial Maximum (LGM, 26,500 to 19,000 y ago, 26.5 to 19 ka) and the ensuing deglaciation.

Sexual intimacy and aging: An integrative framework to promote intimacy resilience in couple therapy.

In our work at the Intimacies Project at The Ackerman Institute for the Family we became aware of a gap in attention about sexuality and aging in the couple and family therapy field. In this article, we provide an integrative framework to guide therapists on how to address problems of sexuality and aging in the therapy room. Starting from considerations about the social context of aging and the self of the therapist, we contend that when normative sexual challenges become entangled with stigma, misconceptions about sexuality, limiting gender narratives, vulnerabilities, and defensive postures, they often result in emotional and sexual shutdowns.

Understanding how people with Parkinson's disease and their relatives approach advance care planning.

Purpose: Advance care planning gives individuals with capacity the option of planning for their future, and anticipating future decision-making about their treatment or care should they then lose capacity. People with Parkinson's disease (PD) may develop significant physical and cognitive problems as the disease progresses, which creates a great need for, but significant challenges to, advance care planning. As a result, we set out to explore the views of people with PD and relatives on planning for the future and advance care planning.

COVID-19 Knowledge and Behavior Change among High School Students in Semi-Rural Georgia.

Background: Many schools transitioned online to reduce viral spread and promote social distancing amid the COVID-19 pandemic. Remote learning may impact health behaviors and coping strategies among adolescents, including reduced physical activity and increased screen time. Social media and peers provide information about the pandemic to adolescents and may influence prevention behaviors.

Biogeography and ecology of Ostracoda in the U.S. northern Bering, Chukchi, and Beaufort Seas.

Ostracoda (bivalved Crustacea) comprise a significant part of the benthic meiofauna in the Pacific-Arctic region, including more than 50 species, many with identifiable ecological tolerances. These species hold potential as useful indicators of past and future ecosystem changes. In this study, we examined benthic ostracodes from nearly 300 surface sediment samples, >34,000 specimens, from three regions-the northern Bering, Chukchi and Beaufort Seas-to establish species' ecology and distribution.

Impact of COVID-19 Pandemic on the Mental Health of Students From 2 Semi-Rural High Schools in Georgia.

Background: Concerns have been raised about the consequences of the COVID-19 pandemic on the mental health of adolescents during an important developmental and social period in their lives. This study examines the mental health impact of the pandemic on high school students shortly after closure of public schools in spring 2020, and whether this impact varies by sex, race/ethnicity, socioeconomic status (SES), and grade level.

Methods: A cross-sectional, one-time online survey was completed by racial/ethnically and socioeconomically diverse students in 9th through 12th grade at 2 semi-rural Georgia public high schools (N = 761).

Strange eyes, stranger brains: exceptional diversity of optic lobe organization in midwater crustaceans.

Nervous systems across Animalia not only share a common blueprint at the biophysical and molecular level, but even between diverse groups of animals the structure and neuronal organization of several brain regions are strikingly conserved. Despite variation in the morphology and complexity of eyes across malacostracan crustaceans, many studies have shown that the organization of malacostracan optic lobes is highly conserved. Here, we report results of divergent evolution to this 'neural ground pattern' discovered in hyperiid amphipods, a relatively small group of holopelagic malacostracan crustaceans that possess an unusually wide diversity of compound eyes.

Mantis shrimp identify an object by its shape rather than its color during visual recognition.

Mantis shrimp commonly inhabit seafloor environments with an abundance of visual features including conspecifics, predators, prey and landmarks used for navigation. Although these animals are capable of discriminating color and polarization, it is unknown what specific attributes of a visual object are important during recognition. Here, we show that mantis shrimp of the species Neogonodactylus oerstedii are able to learn the shape of a trained target.

How Do Patients With Parkinson's Disease Approach Advance Care Planning? A UK-Based Mixed Methods Study.

Background: Advance Care Planning (ACP) allows people the opportunity to plan for a time when they may lose capacity. The aim of this study was to determine the extent people with Parkinson's disease (PD) were aware of ACP, existing plans they held and to explore their own views, as well as their relatives, on planning for the future.

Methods: This was a sequential explanatory mixed methods study with a postal quantitative survey to establish awareness and engagement with planning for the future; and qualitative semi-structured interviews to explore the views of people with PD and their relatives on ACP and future plans.

Visual system characterization of the obligate bat ectoparasite Trichobius frequens (Diptera: Streblidae).

As an obligate ectoparasite of bats, the bat fly Trichobius frequens (Diptera: Streblidae) inhabits the same subterranean environment as their nocturnal bat hosts. In this study, we characterize the macromorphology, optical architecture, rhabdom anatomy, photoreceptor absorbance, and opsin expression of the significantly reduced visual system in T. frequens resulting from evolution in the dark.

Landmark navigation in a mantis shrimp.

Mantis shrimp commonly occupy burrows in shallow, tropical waters. These habitats are often structurally complex where many potential landmarks are available. Mantis shrimp of the species return to their burrows between foraging excursions using path integration, a vector-based navigational strategy that is prone to accumulated error.

Visual metamorphoses in insects and malacostracans: Transitions between an aquatic and terrestrial life.

Arthropods operate in an outrageous diversity of environments. From the deep sea to dense tropical forests, to wide open arctic tundra, they have colonized almost every possible habitat. Within these environments, the presence of light is nearly ubiquitous, varying in intensity, wavelength, and polarization.

Sensory Ecology: In Sea Snake Vision, One Plus One Makes Three.

Snake genomes encode only two opsins for use in retinal cones, limiting their adaptive flexibility and color vision. Research now shows that, by using alternative opsin alleles, some sea snakes may add a third opsin spectral class to their retinas.

Path integration error and adaptable search behaviors in a mantis shrimp.

Mantis shrimp of the species occupy small burrows in shallow waters throughout the Caribbean. These animals use path integration, a vector-based navigation strategy, to return to their homes while foraging. Here, we report that path integration in is prone to error accumulated during outward foraging paths and we describe the search behavior that employs after it fails to locate its home following the route provided by its path integrator.

Mantis Shrimp Navigate Home Using Celestial and Idiothetic Path Integration.

Path integration is a robust mechanism that many animals employ to return to specific locations, typically their homes, during navigation. This efficient navigational strategy has never been demonstrated in a fully aquatic animal, where sensory cues used for orientation may differ dramatically from those available above the water's surface. Here, we report that the mantis shrimp, Neogonodactylus oerstedii, uses path integration informed by a hierarchical reliance on the sun, overhead polarization patterns, and idiothetic (internal) orientation cues to return home when foraging, making them the first fully aquatic path-integrating animals yet discovered.

Exceptional diversity of opsin expression patterns in (Stomatopoda) retinas.

Stomatopod crustaceans possess some of the most complex animal visual systems, including at least 16 spectrally distinct types of photoreceptive units (e.g., assemblages of photoreceptor cells).

Chronic kidney disease-mineral bone disorder.

Chronic kidney disease-mineral bone disorder is typically seen in patients with advanced chronic kidney disease. It is managed primarily by renal physicians, but non-renal physicians are also likely to encounter patients undergoing treatment for this condition in both inpatient and outpatient settings so a basic understanding of the principles may be helpful. This article covers the fundamentals of the pathophysiology, diagnosis and treatment of chronic kidney disease-mineral bone disorder.

Optic lobe organization in stomatopod crustacean species possessing different degrees of retinal complexity.

Stomatopod crustaceans possess tripartite compound eyes; upper and lower hemispheres are separated by an equatorial midband of several ommatidial rows. The organization of stomatopod retinas is well established, but their optic lobes have been studied less. We used histological staining, immunolabeling, and fluorescent tracer injections to compare optic lobes in two 6-row midband species, Neogonodactylus oerstedii and Pseudosquilla ciliata, to those in two 2-row midband species, Squilla empusa and Alima pacifica.

Vision in the snapping shrimp .

Snapping shrimp engage in heterospecific behavioral associations in which their partners, such as goby fish, help them avoid predators. It has been argued that snapping shrimp engage in these partnerships because their vision is impaired by their orbital hood, an extension of their carapace that covers their eyes. To examine this idea, we assessed the visual abilities of snapping shrimp.

Long-Wavelength Reflecting Filters Found in the Larval Retinas of One Mantis Shrimp Family (Nannosquillidae).

Both vertebrates and invertebrates commonly exploit photonic structures adjacent to their photoreceptors for visual benefits. For example, use of a reflecting structure (tapetum) behind the retina increases photon capture, enhancing vision in dim light [1-5]. Colored filters positioned lateral or distal to a photoreceptive unit may also be used to tune spectral sensitivity by selective transmission of wavelengths not absorbed or scattered by the filters [6-8].

Clinical Presentation and Features of Juvenile-Onset Huntington's Disease: A Systematic Review.

Background: Juvenile-onset Huntington's disease (JHD) is defined by onset at the age of 20 or younger and represents approximately 5% of all HD cases. Patients with JHD present with a broad range of symptoms and signs that only overlap partially with adult-onset HD. A greater awareness and understanding of the presentation of JHD would improve the diagnosis and treatment of this condition.

Remobilization of Old Permafrost Carbon to Chukchi Sea Sediments During the End of the Last Deglaciation.

Climate warming is expected to destabilize permafrost carbon (PF-C) by thaw-erosion and deepening of the seasonally thawed active layer and thereby promote PF-C mineralization to CO and CH. A similar PF-C remobilization might have contributed to the increase in atmospheric CO during deglacial warming after the last glacial maximum. Using carbon isotopes and terrestrial biomarkers (ΔC, δC, and lignin phenols), this study quantifies deposition of terrestrial carbon originating from permafrost in sediments from the Chukchi Sea (core SWERUS-L2-4-PC1).
