Exploring the equity of distribution of general medical services funding allocations in Wales: a time-series analysis.

Background: Good access to quality primary care in high-income countries can improve population health. Access to primary care is however often not equal among socioeconomic groups; our analysis sought to explore whether funding, a determinant of service supply, is equitably distributed among GP practices in Wales.

Aim: We sought to explore the relationship between funding and deprivation among GP practices in Wales, to understand the equity of current funding policies.

Understanding and responding to COVID-19 in Wales: protocol for a privacy-protecting data platform for enhanced epidemiology and evaluation of interventions.

Introduction: The emergence of the novel respiratory SARS-CoV-2 and subsequent COVID-19 pandemic have required rapid assimilation of population-level data to understand and control the spread of infection in the general and vulnerable populations. Rapid analyses are needed to inform policy development and target interventions to at-risk groups to prevent serious health outcomes. We aim to provide an accessible research platform to determine demographic, socioeconomic and clinical risk factors for infection, morbidity and mortality of COVID-19, to measure the impact of COVID-19 on healthcare utilisation and long-term health, and to enable the evaluation of natural experiments of policy interventions.

Expression of kappa opioid receptors in developing rat brain - Implications for perinatal buprenorphine exposure.

Buprenorphine, a mu opioid receptor partial agonist and kappa opioid receptor (KOR) antagonist, is an emerging therapeutic agent for maternal opioid dependence in pregnancy and neonatal abstinence syndrome. However, the endogenous opioid system plays a critical role in modulating neurodevelopment and perinatal buprenorphine exposure may detrimentally influence this. To identify aspects of neurodevelopment vulnerable to perinatal buprenorphine exposure, we defined KOR protein expression and its cellular associations in normal rat brain from embryonic day 16 to postnatal day 23 with double-labelling immunohistochemistry.

Using social media to support small group learning.

Background: Medical curricula are increasingly using small group learning and less didactic lecture-based teaching. This creates new challenges and opportunities in how students are best supported with information technology. We explored how university-supported and external social media could support collaborative small group working on our new undergraduate medical curriculum.

The Severity of Gliosis in Hippocampal Sclerosis Correlates with Pre-Operative Seizure Burden and Outcome After Temporal Lobectomy.

Astrogliosis and microgliosis in hippocampal sclerosis (HS) are widespread and are postulated to contribute to the pro-excitatory neuropathological environment. This study aimed to establish if seizure burden at the time of surgery or post-surgical outcome were correlated with the extent of gliosis in HS. As a secondary aim, we wanted to determine if the degree of gliosis could be predicted by pre-operative neuroimaging.

Thou shalt not tweet unprofessionally: an appreciative inquiry into the professional use of social media.

Background: Social media may blur the line between socialisation and professional use. Traditional views on medical professionalism focus on limiting motives and behaviours to avoid situations that may compromise care. It is not surprising that social media are perceived as a threat to professionalism.

Clinicopathological associations in temporal lobe epilepsy patients utilising the current ILAE focal cortical dysplasia classification.

Objectives: This study utilised the revised 2011 ILAE classification of focal cortical dysplasia (FCD) (Blümcke et al., 2011) to examine pathology in a cohort of children and adults who underwent temporal lobe epilepsy (TLE) surgery, and to describe the electroclinical and imaging features associated with these pathologies.

Methods: The sample population were children (n=26) and adults (n=47) who underwent TLE surgery between 2002 and 2011 at our institutions.

Blended learning in health education: three case studies.

Blended learning in which online education is combined with face-to-face education is especially useful for (future) health care professionals who need to keep up-to-date. Blended learning can make learning more efficient, for instance by removing barriers of time and distance. In the past distance-based learning activities have often been associated with traditional delivery-based methods, individual learning and limited contact.

Selective inhibition of human group IIA-secreted phospholipase A2 (hGIIA) signaling reveals arachidonic acid metabolism is associated with colocalization of hGIIA to vimentin in rheumatoid synoviocytes.

Human group IIA secreted phospholipase A2 (hGIIA) promotes tumor growth and inflammation and can act independently of its well described catalytic lipase activity via an alternative poorly understood signaling pathway. With six chemically diverse inhibitors we show that it is possible to selectively inhibit hGIIA signaling over catalysis, and x-ray crystal structures illustrate that signaling involves a pharmacologically distinct surface to the catalytic site. We demonstrate in rheumatoid fibroblast-like synoviocytes that non-catalytic signaling is associated with rapid internalization of the enzyme and colocalization with vimentin.

The retinoid signalling molecule, TRIM16, is repressed during squamous cell carcinoma skin carcinogenesis in vivo and reduces skin cancer cell migration in vitro.

Retinoid therapy is used for chemo-prevention in immuno-suppressed patients at high risk of developing skin cancer. The retinoid signalling molecule, tripartite motif protein 16 (TRIM16), is a regulator of keratinocyte differentiation and a tumour suppressor in retinoid-sensitive neuroblastoma. We sought to determine the role of TRIM16 in skin squamous cell carcinoma (SCC) pathogenesis.

Reaction of endogenous progenitor cells in a rat model of posttraumatic syringomyelia.

Object: Endogenous stem cells theoretically could replace lost tissue and repair deficits caused by syringes. In this study the authors quantitatively examined 1) whether neural progenitor cells exist in an adult rat model of posttraumatic syringomyelia (PTS); 2) and if so, how long an active population of progenitor cells can persist; 3) whether the cell population's location is associated with the syrinx; 4) the degree of differentiation of the progenitor cells; and 5) the phenotypic fate of the progenitor cells.

Methods: Wistar rats were divided into intact, sham-operated, and experimental syrinx groups.

Differentiation of endogenous progenitors in an animal model of post-traumatic syringomyelia.

Study Design: An in vivo study to examine the differentiation of endogenous neural progenitor cells in an adult rat model of post-traumatic syringomyelia.

Objective: To quantitatively evaluate the phenotypic fate of endogenous neural progenitor cells in post-traumatic syringomyelia.

Summary Of Background Data: Although neural progenitors have been identified in the central nervous system, their differentiation in experimental post-traumatic syringomyelia and possible role in the pathophysiology of this condition have not been investigated.

Class I beta-tubulin mutations in 2-methoxyestradiol-resistant acute lymphoblastic leukemia cells: implications for drug-target interactions.

2-Methoxyestradiol (2ME2) is a naturally occurring derivative of estradiol that has been shown to be an active small molecule that has antitumor and antiangiogenic properties. 2ME2 binds to beta-tubulin near the colchicine-binding site, inhibits microtubule polymerization, and induces mitotic arrest. To improve understanding of the mechanisms of action and resistance to 2ME2, we selected leukemia cells, CCRF-CEM, that display increasing resistance to 2ME2, and three of the highly resistant sublines were chosen for detailed analysis.

Serum and mucosal S100 proteins, calprotectin (S100A8/S100A9) and S100A12, are elevated at diagnosis in children with inflammatory bowel disease.

Objective: Various markers characterize the complex inflammatory processes seen in chronic inflammatory bowel disease (IBD) including calprotectin, a complex of two S100 proteins, which has been evaluated and validated as a faecal marker of inflammation. However, the systemic and mucosal expression patterns of calprotectin and related S100 proteins are not well characterized in this disease. The objective of this study was to assess serum and mucosal levels of calprotectin, S100A12 and soluble receptor for advanced glycation end products (sRAGE), a putative S100 ligand, in a paediatric population with IBD.

Immunohistochemical expression of two members of the GDNF family of growth factors and their receptors in the olfactory system.

The glial cell line-derived (GDNF) family of trophic factors, GDNF, neurturin, persephin and artemin, are known to support the survival and regulate differentiation of many neuronal populations, including peripheral autonomic, enteric and sensory neurons. Members of this family of related ligands bind to specific GDNF family receptor (GFR) proteins, which complex and signal through the Ret receptor tyrosine kinase. We showed previously that GDNF protein was detectable in olfactory sensory neurons (OSNs) in the olfactory neuroepithelium (ON).

Evaluation of a service development to increase detection of urinary tract infections in children.

Rationale, Aims And Objectives: It is suspected that childhood urinary tract infection (UTI) remains under-diagnosed in primary care, and is consequently the cause of subsequent morbidity from renal scarring, hypertension and eventual renal failure. Practice-based education and service developments were undertaken to try to improve the detection of childhood UTI.

Methods: A controlled before-and-after intervention study was conducted.

Application of statistical parametric mapping to SPET in the assessment of intractable childhood epilepsy.

Statistical parametric mapping (SPM) quantification and analysis has been successfully applied to functional imaging studies of partial epilepsy syndromes in adults. The present study evaluated whether localisation of the epileptogenic zone (determined by SPM) improves upon visually examined single-photon emission tomography (SPET) imaging in presurgical assessment of children with temporal lobe epilepsy (TLE) and frontal lobe epilepsy (FLE). The patient sample consisted of 24 children (15 males) aged 2.

Intelligence in childhood epilepsy syndromes.

Unlabelled: Intellectual deficits play a significant role in the psychosocial comorbidity of children with epilepsy. Early educational intervention is critical.

Objective: This study aims to determine the intellectual ability of children with common childhood epilepsy syndromes-generalised idiopathic epilepsy (GIE), generalised symptomatic epilepsy (GSE), temporal lobe epilepsy (TLE), frontal lobe epilepsy (FLE), central epilepsy (CE) and non-localised partial epilepsy (PE).
