Background: Ireland is experiencing a general practitioner (GP) workforce crisis, facing an ageing workforce, a growing population with increased life expectancy, and increased complexity of patients. The GP crisis threatens access to primary care in Ireland, as well as Ireland's aim to transform into a primary-care centred system of universal healthcare via the proposed "Sláintecare" healthcare reforms. The challenges faced are common to many countries as health systems seek to expand their medical workforce post-pandemic.

Article Synopsis
  • Climate change is causing shifts in animal habitats, particularly affecting the distribution of threatened marine species like whale sharks.
  • Projections indicate that by 2100, whale sharks could lose more than 50% of their core habitat in some areas, with significant geographic shifts that could place them in closer proximity to large ships.
  • The increase in whale shark interaction with shipping is expected to be dramatically higher under high emission scenarios compared to sustainable development, highlighting the urgency for better climate-threat predictions in conservation strategies for endangered marine life.

Hyperglycemia-induced involuntary movements (HIIM) include tremors, hemichorea-hemiballismus (HCHB), and more rarely, dystonia. Presentations may vary, but hyperintensity involving the basal ganglia area on the T1 sequence of MRI brain remains a commonality.  We report the occurrence of focal dystonia with uncontrolled hyperglycemia but no focal abnormalities on MRI.

Background During the COVID-19 pandemic, many hospitals suspended non-essential medical procedures to reduce transmission and prioritize personal protective equipment (PPE) for COVID-19 patients. Hospitals that continued these procedures faced uncertainty about patient attendance. Multiple factors could explain a decline in patient attendance during the pandemic, including patients' reluctance to risk COVID-19 exposure in the hospital or their own illness requiring self-isolation.

As studied previously, chronic stress environments lead to the formation of distinctive resilience groupings when related to individual outcomes among participants. The majority of the population has decreased mental and physical strength during prolonged periods of mental distress but returns to baseline status when those stressors are removed. Others have increased and decreased mental fortitude despite the removal of stressors.

Levels of dissolved oxygen in open ocean and coastal waters are decreasing (ocean deoxygenation), with poorly understood effects on marine megafauna. All of the more than 1000 species of elasmobranchs (sharks, skates, and rays) are obligate water breathers, with a variety of life-history strategies and oxygen requirements. This review demonstrates that although many elasmobranchs typically avoid hypoxic water, they also appear capable of withstanding mild to moderate hypoxia with changes in activity, ventilatory responses, alterations to circulatory and hematological parameters, and morphological alterations to gill structures.

The sharing of information and feedback directly from service-providing staff to healthcare organisational management is vital for organisational culture and service improvement. However, hospital doctors report feeling unable to communicate effectively with management to provide evidence and affect improvement, and this can impact job satisfaction, workplace relations, service delivery and ultimately patient safety. In this paper, we draw on data elicited from a Mobile Instant Messaging Ethnography (MIME) study involving 28 hospital doctors working in Irish hospitals, to explore the barriers preventing them from speaking up and effecting change, and the impact of this on staff morale and services.

Unlabelled: Oxygen minimum zones in the open ocean are predicted to significantly increase in volume over the coming decades as a result of anthropogenic climatic warming. The resulting reduction in dissolved oxygen (DO) in the pelagic realm is likely to have detrimental impacts on water-breathing organisms, particularly those with higher metabolic rates, such as billfish, tunas, and sharks. However, little is known about how free-living fish respond to low DO environments, and therefore, the effect increasing OMZs will have cannot be predicted reliably.

Introduction: A shortage of doctors is currently one of the biggest challenges faced by the healthcare workforce in the United Kingdom (UK). While plans are in place to increase the number of medical school places, in the short-term this gap will need to continue to be filled by the international recruitment of doctors. The aim of this study is to identify key factors that explain the patterns of migration of doctors to the UK, in order to aid the development of policies to recruit and retain a sustainable workforce.

Introduction: Globally, an epidemic of psychological distress, burnout, and workforce attrition signify an acute deterioration in hospital doctors' relationship with their work-intensified by COVID-19. This deterioration is more complicated than individual responses to workplace stress, as it is heavily regulated by social, professional, and organizational structures. Moving past burnout as a discrete "outcome," we draw on theories of emotion management and alienation to analyze the strategies through which hospital doctors in the face of resource-constraints and psychological strain.

Healthcare worker (HCW) mental well-being has become a global public health priority as health systems seek to strengthen their resilience in the face of the COVID-19 pandemic. Analysing data from the Health System Response Monitor, we present six case studies (Denmark, Italy, Kyrgyzstan, Lithuania, Romania, and the United Kingdom) as a comparative review of policy interventions supporting HCW mental health during the pandemic. The results illustrate a wide range of interventions.

The shortfin mako shark is a large-bodied pursuit predator thought to be capable of the highest swimming speeds of any elasmobranch and potentially one of the highest energetic demands of any marine fish. Nonetheless, few direct speed measurements have been reported for this species. Here, animal-borne bio-loggers attached to two mako sharks were used to provide direct measurements of swimming speeds, kinematics and thermal physiology.

Biosolids are applied to agricultural land as a soil conditioner and source of crop nutrients. However, there is concern that bacteria from biosolids may become established in soils, particularly if that soil becomes water-logged. This study examined the microbial community of arable soils cultivated with barley under different applications of biosolids (0, 24t/ha, 48t/ha) in laboratory mesocosms which simulated a 10-day flood.

The understanding of what ethnography looks like, and its purpose, is continuously evolving. COVID-19 posed a significant challenge to ethnographers, particularly those working in health-related research. Researchers have developed alternative forms of ethnography to overcome some of these challenges; we developed the Mobile Instant Messaging Ethnography (MIME) adaptation to ethnography in 2021 to overcome restrictions to our own research with hospital doctors.

Groups of basking sharks engaged in circling behaviour are rarely observed, and their function remains enigmatic in the absence of detailed observations. Here, underwater and aerial video recordings of multiple circling groups of basking sharks during late summer (August and September 2016-2021) in the eastern North Atlantic Ocean showed groups numbering between 6 and 23 non-feeding individuals of both sexes. Sharks swam slowly in a rotating "torus" (diameter range: 17-39 m), with individuals layered vertically from the surface to a maximum depth of 16 m.

Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species.

Marine traffic is increasing globally yet collisions with endangered megafauna such as whales, sea turtles, and planktivorous sharks go largely undetected or unreported. Collisions leading to mortality can have population-level consequences for endangered species. Hence, identifying simultaneous space use of megafauna and shipping throughout ranges may reveal as-yet-unknown spatial targets requiring conservation.

Objectives: COVID-19 has prompted the reconfiguration of hospital services and medical workforces in countries across the world, bringing significant transformations to the work environments of hospital doctors. Before the pandemic, the working conditions of hospital doctors in Ireland were characterised by understaffing, overload, long hours and work-life conflict. As working conditions can affect staff well-being, workforce retention and patient outcomes, the objective of this study was to analyse how the pandemic and health system response impacted junior hospital doctors' working conditions during the first wave of COVID-19 in Ireland.

The coronavirus disease 2019 (COVID-19) pandemic poses a challenge to the physical and mental well-being of doctors worldwide. Countries around the world introduced severe social restrictions, and significant changes to health service provision in the first wave of the pandemic to suppress the spread of the virus and prioritize healthcare for those who contracted it. This study interviewed 48 hospital doctors who worked in Ireland during the first wave of the pandemic and investigated their conceptualizations of their own well-being during that time (March-May 2020).
