DL enables 40% spine MRI scan time reduction while maintaining diagnostic integrity and image quality with perceived benefits in SNR and artifact reduction, suggesting potential for clinical practice utility.The COVID-19 pandemic and social distancing restrictions have significantly reduced population-wide physical activity (PA) levels. However, the impact of the pandemic and relevant restrictions on PA participation, and any potential barriers to it, in people with rheumatoid arthritis (RA) are not clear. Furthermore, we are unsure if any such PA changes have affected their body weight, mental wellbeing, and/or quality of life (QoL). Thus, the aim of this study was to examine the impact of the lockdown on PA participation in people with RA, versus people without RA. Participants (n = 128; RA = 27, non-RA = 101) completed a self-administered online survey, which included questions on PA, body weight, mental wellbeing and QoL. PA participation during lockdown was significantly lower among RA versus non-RA participants (p less then 0.001). Additionally, a similar profile of results was found where more RA participants vs non-RA participants reported reduced habitual PA (59% vs 33%) and increased body weight (59% vs 35%). Mental wellbeing scores were similarly low in both groups during lockdown (RA 20.8 ± 4.2; non-RA 22.2 ± 3.4, p = 0.080). Matched group comparisons identified similar trends to full sample analyses. In the first months of the lockdown, more people with RA reported decreased PA participation and increased body weight than their non-RA counterparts. Access to exercise equipment and facilities appears to be the main cause for these results. Looking beyond COVID-19, specific PA promotion for people with RA will be required to prevent a pandemic of inactivity.The legal basis for describing the regional care situation is based on the adjusted supply rate of the 'demand planning guideline'. However, it provides only limited information about the accessibility of medical care which is crucial for the reality of patients' lives. The aim of this review is to present geographic approaches that spatially measure access to dermatological care in its physical and digital dimension. Here, on the one hand, the classical geographic parameter 'accessibility' is addressed, and on the other hand, data from the Federal Ministry of Transport and Digital Infrastructure (BMVI) on broadband coverage are presented as access parameters of teledermatological applications. In addition to the methodological approach, limitations and potentials in the interpretation of the results, minimum standards are also considered. The access parameters presented here make it possible to investigate spatial disparities and to present them clearly via cartographic representations. While the example of accessibility with a car shows almost area-wide access to the nearest dermatology practice (≤ 30 min), investigations on public transport accessibility reveal rather heterogeneous accessibility. Particularly in the identification of 'dual care gaps', sub-areas with poor physical and digital accessibility, these approaches could support and advance the application of alternative care models. However, the approaches presented here focus on potential accessibility. Further dimensions on actual physician utilisation or availability-also with regard to minimum standards-should be the subject of future research.The association between geographic and medical aspects is a well-known phenomenon, which also occurs in dermatological research. This article reviews the field of health geography, the history of the association between spatial location and health, and focuses on current areas of research. Research focusing on explaining regional variations in health refer to individual aspects and needs, population factors, environmental factors, and health care delivery structures in specific regions, as well as the interaction between them. Regional healthcare research is primarily concerned with access to health services and on the utilisation of those services. Methodologically, the analysis of geodata and the application of geographic information systems (GIS) and spatial modelling play a major role in this field. KRpep2d Dermatological research and dermatological practice can benefit from the findings of the regional analysis of access, utilisation, and variations in order to obtain a more detailed picture of care and thus to optimise care.
Studies show aspatial variation in skin cancer frequencies, but the causes have not been fully understood. When analysing spatial patterns and correlations, different approaches need to be considered, as the data have special features due to their spatial structure.
Why the spatial consideration of skin cancer frequencies is important at all, and which methods of analysis are useful is considered in more detail in this article. The article provides an introduction and overview of statistical methods that are important for the spatial analysis of skin cancer frequencies.
At first it is shown which descriptive methods, such as statistical smoothing, can be applied. Next, spatial cluster and regression analyses will be discussed. Testing for spatial autocorrelation will be considered.
In particular, the spatial dependence of the data on neighbouring regions, which if ignored can lead to biased estimates, is of particular importance in the analysis of spatial data and requires special spatial analysis methods.

Lateral pelvic lymph node dissection (LPLND) may improve oncological outcomes for select patients with rectal cancer, though functional outcomes may be adversely impacted.The aim of this study is to assess the functional outcomes associated with LPLND for rectal cancer and compare these outcomes with standard surgical resection.
A systematic search was undertaken to identify relevant studies reporting on urinary dysfunction (UD), sexual dysfunction (SD), and defecatory dysfunction (DD) for patients who underwent LPLND for rectal cancer. Studies comparing functional outcomes in patients who underwent surgery with and without LPLND were assessed. In addition, a comparison of functional outcomes in patients who underwent LPLND before and after the year 2000 was performed.
Twenty-one studies of predominantly non-randomised observational data were included. Ten were comparative studies. Male SD was worse in patients who underwent LPLND compared with those who did not (RR 1.68 (95% CI 1.41-1.99, P < 0.001)). No difference was observed for the rate of UD between treatment groups. The rates of UD and male SD in patients who underwent LPLND after the year 2000 were significantly lower than those who underwent LPLND before the year 2000 ((UD) RR = 4.5, p value = 0.0034; male SD RR = 28.7, p value < 0.001).
Lateral pelvic lymph node dissection is associated with worse male sexual dysfunction compared to standard surgical resection. However, the rates of urine dysfunction and male sexual dysfunction are better in contemporary cohorts which may reflect improved surgical technique and autonomic nerve preservation.

Therefore, a correct and rapid diagnosis is of essential importance. Measurement of the aldosterone-renin ratio is used as a first screening test for primary aldosteronism. This should ideally be evaluated under optimized conditions (e.g. at rest), after adjustment of the blood pressure medication and with an equilibrated potassium balance. In cases of elevated aldosterone to renin ratio, further confirmatory testing as well as imaging of the adrenal glands is needed. After confirmation of Conn's syndrome a differentiation between a unilateral and bilateral adrenal disease is necessary for further treatment planning. The current gold standard is still selective adrenal vein catheterization. Promising alternatives to an adrenal vein catheter, such as functional imaging techniques and measurement of steroid profiles are currently being investigated in clinical trials. In cases of lateralization of aldosterone production, unilateral laparoscopic adrenalectomy of the affected side is the treatment of choice. In contrast, patients with bilateral disease or patients with contraindications for adrenalectomy should receive life-long treatment with mineralocorticoid receptor antagonists.Pain is one of the most common reasons to seek medical attention, and chronic pain is a worldwide epidemic. Anecdotal reports suggest cannabis may be an effective analgesic. As cannabis contains the terpenes α-terpineol, β-caryophyllene, and γ-terpinene, we hypothesized these terpenes would produce analgesia in a mouse model of neuropathic pain. We used the chronic constriction injury of the sciatic nerve mouse model, which produces mechanical allodynia, assessed via the von Frey assay, as well as thermal hyperalgesia assessed via the hotplate assay. Compounds were further assessed in tests of locomotor activity, hypothermia, and acute antinociception. Each terpene produced dose-related reversal of mechanical allodynia and thermal hyperalgesia. Thermal hyperalgesia displayed higher sensitivity to the effects of each terpene than mechanical allodynia, and the rank order potency of the terpenes was α-terpineol > β-caryophyllene > γ-terpinene. To examine the involvement of cannabinoid receptors, further tests were conducted in mice lacking either functional cannabinoid type 1 receptors (CB1R (-/-)) or cannabinoid type 2 receptors (CB2R (-/-)). Compared to wild type mice, CB1R (-/-) mice treated with α-terpineol displayed a 2.91-fold decrease in potency to reverse mechanical allodynia; in CB2R (-/-) mice, the potency of α-terpineol was decreased 11.73-fold. The potency of β-caryophyllene to reverse mechanical allodynia decreased 1.80-fold in CB2R (-/-) mice. Each terpene produced a subset of effects in tests of locomotor activity, hypothermia, and acute antinociception. These findings suggest α-terpineol, β-caryophyllene, and γ-terpinene may have differential cannabinoid receptor activity and a pharmacological profile that may yield new efficacious analgesics.
The Global Initiative for Children's Surgery (GICS) group produced the Optimal Resources for Children's Surgery (OReCS) document in 2019, listing standards of children's surgical care by level of healthcare facilities within low resource settings. We have previously created and piloted an audit tool based on the OReCS criteria in a high-income setting. In this study, we aimed to validate its use in identifying gaps in children's surgery provision worldwide.
Our OReCS audit tool was implemented in 10 hospitals providing children's surgery across eight countries. Collaborators were recruited via the Oxford Paediatrics Linking Our Research with Electives (OxPLORE) international network of medical students and trainees. The audit tool measured a hospital's current capacity for children's surgery. Data were analysed firstly to express the percentage of 'essential' criteria met for each specialty. Secondly, the 'OxPLORE method' was used to allocate each hospital specialty a level based on procedures performed and resources available.
