Abstract
Abstract
Background
Blogging can help to maximise the impact of one’s work in academia and beyond by making research findings accessible for multiple knowledge users. As part of the knowledge exchange and dissemination activities of the Model for Dementia Palliative Care Project, this study explored stakeholders’ views of blogs as a means to translate research findings in the field of Dementia Palliative care.
Methods
A web-based survey was developed, piloted, and revised. It was distributed electronically via key dementia and palliative care organisations. Complete responses (N=128) were received from healthcare researchers (n=53), healthcare providers (n=46) and others with an interest in healthcare research (n=29). Data were analysed using descriptive statistics and content analysis
Results
The preferred methods of reviewing research findings were scientific papers, websites and news articles. Respondents read healthcare blogs “sometimes” (39.1%), with <19% reading them “often” or “very often”. Receiving an email notification might increase the likelihood of reading a new blog post for 83% of respondents. Barriers to engaging with blogs included lack of time, preference for other media, lack of awareness regarding available blogs, and concerns about the credibility and source of information. An appropriate length and the author of the blog were key features that encouraged engagement with a blog. Most respondents (37.7 % ‘Yes’ and 23.0% ‘Maybe’) would read Dementia Palliative care blogs by the research team.
Conclusion
Despite respondents choosing a scientific paper as their preferred method to consume research findings, many indicated an openness to reading blogs on their area of interest. Creating concise, relevant, and credible blogs, and suitably promoting them, could increase the impact and reach of healthcare research, such as in the emerging field of dementia palliative care, and thus promote translation of research findings into practice.

Abstract
Abstract
Background
Dementia is a life-limiting illness, requiring a Palliative Care (PC) approach from diagnosis. In Ireland, People with Dementia (PwD) and their families rarely receive PC in a timely manner. This study aimed to evaluate five exemplar community-based dementia PC services across Ireland and the UK (as identified by key stakeholders), to inform a new service delivery model.
Methods
Data from semi-structured interviews and focus groups with 29 service providers, and service activity data (n=5), was evaluated using the RE-AIM framework.
Results
‘Reach’ - Caseloads varied significantly between 3-154 active cases. Most services accepted self-referrals; all wanted earlier referrals. Factors influencing reach included co-location, dyadic participation, service flexibility, and others’ awareness of PC appropriateness and the service’s existence.
‘Effectiveness’ - All service users received holistic assessments, person-centred care, advanced care planning, continuity of care, improved service access and ‘care-for-the-carer’. Some services offered complimentary therapies, 24/7 phone support, and bereavement support; these were perceived to improve quality-of-life, comfort, and independence.
‘Adoption’ - Staff were highly invested; some provided their personal numbers to families. Outside staff were more willing to engage (refer/support) if shared governance, training was provided, or already familiar with dementia or the tools. Incentive programmes increased adoption rates.
‘Implementation ’ - All services evolved on an ad-hoc basis, with funding provided by local organisations, and a single ‘driving force’, typically a consultant/nurse. Services heavily relied on volunteers. Perceived “essential” elements included a dyadic approach, MDT involvement, open communication, forming relationships, reflective practices, dedicated staff with problem solving skills, and staff support/training.
‘Maintenance’ - All services continued after initial project funding; three increased their activities/reach over time.
Conclusion
Important features and facilitators of community-based dementia palliative care services have been identified. These results are informing the development of the novel Dementia Palliative Care model for use in Ireland (https://pallcare4dementia.com/).

Abstract
Abstract
Aims
Clearance of choledocholithiasis reduces recurrent cholangitis, but following clearance of the CBD, cholecystectomy is required. This meta-analysis evaluated outcomes in patients undergoing ERCP with or without sphincterotomy to determine if cholecystectomy post ERCP clearance offers more favourable outcomes than a wait-and-see approach.
Methods
A Prospero-registered meta-analysis of the literature using PRISMA guidelines incorporating articles relating to ERCP, choledocholithiasis, cholangitis and cholecystectomy was undertaken for papers published between 1st January 1991 and 31st May 2021. Existing research demonstrating outcomes of ERCP with no cholecystectomy versus ERCP and cholecystectomy was reviewed to determine key events, complications, and mortality. Odds Ratios (OR) were calculated using Review Manager Version 5.4 and meta-analyses using OR with either fixed- or random-effect models, depending on heterogeneity of studies.
Results
13 studies (n=2,598), published between 2002 and 2019 were included in this meta-analysis: six retrospective studies, two retrospective propensity score matched studies, three prospective studies and two randomised control trials from a total of 11 countries. There were 1,433 in the no cholecystectomy cohort (55.2%) and 1,165 in the prophylactic cholecystectomy cohort (44.8%). Cholecystectomy resulted in a decreased risk of cholecystitis (OR= 0.15; CI, 0.07–0.36; p<0.0001), cholangitis (OR= 0.51; CI; 0.26–1.00; p=0.05) and mortality (OR= 0.38; CI; 0.16–0.9; p=0.03). In addition, prophylactic cholecystectomy resulted in a significant reduction in biliary events, biliary pain and pancreatitis.
Conclusions
In patients undergoing CBD clearance consideration should be given to performing prophylactic cholecystectomy to optimise outcomes.

It's time for a minimum synoptic operation template in patients undergoing laparoscopic cholecystectomy: a systematic review. World J Emerg Surg 2022; 17:15. [PMID: 35296354 PMCID: PMC8928637 DOI: 10.1186/s13017-022-00411-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Accepted: 01/07/2022] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Despite the call to enhance accuracy and value of operation records few international recommended minimal standards for operative notes documentation have been described. This study undertook a systematic review of existing operative reporting systems for laparoscopic cholecystectomy (LC) to fashion a comprehensive, synoptic operative reporting template for the future. METHODS A search for all relevant articles was conducted using PubMed version of Medline, Scopus and Web of Science databases in June 2021, for publications from January 1st 2011 to October 25th 2021, using the keywords: laparoscopic cholecystectomy AND operation notes OR operative notes OR proforma OR documentation OR report OR narrative OR audio-visual OR synoptic OR digital. Two reviewers (NOC, GMC) independently assessed each published study using a MINORS score of ≥ 16 for comparative and ≥ 10 for non-comparative for inclusion. This systematic review followed PRISMA guidelines and was registered with PROSPERO. Synoptic operative templates from published data were assimilated into one "ideal" laparoscopic operative report template following international input from the World Society of Emergency Surgery board. RESULTS A total of 3567 articles were reviewed. Following MINORS grading 25 studies were selected spanning 14 countries and 4 continents. Twenty-two studies were prospective. A holistic overview of the operative procedure documentation was reported in 6/25 studies and a further 19 papers dealt with selective surgical aspects of LC. A unique synoptic LC operative reporting template was developed and translated into Chinese/Mandarin, French and Arabic. CONCLUSION This systematic review identified a paucity of publications dealing with operative reporting of LC. The proposed new template may be integrated digitally with hospitals' medical systems and include additional narrative text and audio-visual data. The template may help define new OR (operating room) recording standards and impact on care for patients undergoing LC.

Abstract
OBJECTIVE To analyse the relative percentage of acute recreational drug toxicity emergency department (ED) presentations involving the main drug groups according to age and sex and investigate different patterns based on sex and age strata. METHODS We analysed all patients with acute recreational drug toxicity included by the Euro-DEN Plus dataset (22 EDs in 14 European countries) between October 2013 and December 2016 (39 months). Drugs were grouped as: opioids, cocaine, cannabis, amphetamines, gamma-hydroxybutyrate (GHB), hallucinogens, new psychoactive substances (NPS), benzodiazepines and ketamine. Descriptive data by age and sex are presented and compared among age/sex categories and among drug families. RESULTS Of 17,371 patients were included during the 39-month period, 17,198 (99.0%) had taken at least one of the investigated drugs (median age: 31 years; 23.9% female; ethanol co-ingestion recorded in 41.5%, unknown in 31.2%; multiple drug use in 37.9%). Opioids (in 31.4% of patients) and amphetamines (23.3%) were the most frequently involved and hallucinogens (1.9%) and ketamine (1.7%) the least. Overall, female patients were younger than males, both in the whole cohort (median age 29 vs. 32 years; p < 0.001) and in all drug groups except benzodiazepines (median age 36 vs. 36 years; p = 0.83). The relative proportion of each drug group was different at every age strata and some patterns could be clearly described: cannabis, NPS and hallucinogens were the most common in patients <20 years; amphetamines, ketamine and cocaine in the 20- to 39-year group; GHB/GBL in the 30- to 39-year group; and opioids and benzodiazepines in patients ≥40 years. Ethanol and other drug co-ingestion was more frequent at middle-ages, and multidrug co-ingestion was more common in females than males. CONCLUSION Differences in the drugs involved in acute drug toxicity presentations according to age and sex may be relevant for developing drug-prevention and education programs for some particular subgroups of the population based on the increased risk of adverse events in specific sex and/or age strata.

A systematic review of the complications of high-risk third molar removal and coronectomy: development of a decision tree model and preliminary health economic analysis to assist in treatment planning. Br J Oral Maxillofac Surg 2020; 58:e16-e24. [PMID: 32800608 DOI: 10.1016/j.bjoms.2020.07.015] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Accepted: 07/13/2020] [Indexed: 10/23/2022]
Abstract
Coronectomy is an alternative surgical technique for the management of high-risk third molars. It involves the removal of the crown of a tooth and the deliberate retention of the roots, thereby avoiding injury to the inferior alveolar nerve (IAN). Previous studies have suggested that it reduces the risk of nerve injury when compared with surgical extraction. The purpose of this study was to systematically review the incidence of complications following coronectomy such as IAN injury, pain, dry socket, infection, root migration, and need for re-operation. A comparative cost analysis of coronectomy and surgical extraction was done based on the results of the review. This provides an insight into the economic implications of the two procedures. A search through the MEDLINE database via Ovid, PubMed, Scopus, EMBASE via Ovid, and Web of Science, was carried out to extract randomised and non-randomised controlled trials. Four studies fulfilled the inclusion criteria. A meta-analysis was conducted to measure the overall effect of each outcome. The pooled odds ratio (OR) for IAN injury was 0.16 (95% CI 0.01 to 0.39). Coronectomy reduced this risk by 84%. Dry socket may occur less frequently following coronectomy whereas infection did not show a higher incidence with either intervention. Root migration was found to occur in 13%-85% of cases and the average incidence of re-operation was 2.2%. The ratio of the average costs was 1.12 favouring coronectomy if cone-beam computed tomography (CBCT) was not done prior to the procedure. If a scan was taken routinely for coronectomy, the cost ratio marginally favoured extraction. Coronectomy reduced the risk of nerve injury in high-risk third molars. Definitive conclusions, however, cannot be made for outcomes such as the need for re-operation, which may alter the cost ratio of coronectomy:extraction, as higher quality studies with longer follow-up are needed.

Abstract
26 Background: Utilization of NGS-based testing for patients in community oncology settings continues to grow. A comprehensive analysis of the molecular landscape of > 14,000 patients with commercial tissue-based and plasma-based NGS (tbNGS and pbNGS) testing from Sarah Cannon’s (SC) network of community oncologists between 2012 and 2018 was performed. These data aid clinical trial design/feasibility and identify rare and actionable mutations in the community oncology setting. Methods: Medical Oncologists in the SC network ordered NGS-based molecular profiling for their patients as standard of care. Data from multiple commercial vendors starting in 2012 were harmonized and analyzed. Results: On average, tbNGS (n = 8938) and pbNGS (n = 5419) tests revealed 14 and 4 mutations/sample, respectively. The top 10 mutated genes from both tbNGS and pbNGS - tests are in the table. The most predominant mutation-types detected were SNVs in both tbNGS and pbNGS tests, and gene amplifications were detected in ~40% of tbNGS and ~22% of pbNGS tests. MET amplifications (range: 2 - 40 copies (pbNGS) and 6 - 82 copies (tbNGS)) and ERBB2 amplifications (range: 2.1 - 90.2 copies (pbNGS) and 4 - 293 copies (tbNGS)) were detected in 1.6% (MET-tbNGS) and 4.6% (MET-pbNGS) and 4.2% (ERBB2-tbNGS) and 2.69% (ERBB2-pbNGS) of patients, respectively, and informed clinical trial enrollment. Of the fusions detected, 28 NTRK rearrangements were detected (NTRK1 – 16, NTRK2 – 5, NTRK3 – 7) by tissue-based testing and 3 (NTRK1) fusions were detected by plasma-based tests. Conclusions: These data describe the mutational landscape of NGS tests ordered within community oncology practices. SC’s data infrastructure links NGS-based testing data and clinical data to support real world evidence research, and highlights the need for healthcare IT systems to marry clinical and genomic data for clinical decision support and clinical research.

Abstract
OBJECTIVES To analyze epidemiologic, clinical, and care characteristics in cases in which patients came to 2 Spanish emergency departments (EDs) with symptoms caused by recreational drug abuse. To compare the characteristics with those reported for other areas of Europe. MATERIAL AND METHODS Secondary analysis of the registry of the European Drug Emergencies Network (Euro-DEN Plus), which collects cases in 14 European countries and 20 EDs. The registry included all patients attending EDs with symptoms of recreational drug abuse (excepting cases involving alcohol alone) over a period of 39 consecutive months (October 2013 to December 2016). We compared the cases from the 2 Spanish EDs (in Barcelona and Palma de Mallorca) to those from the 5 EDs in Ireland and the UK, 6 in northern Europe, and 7 in central Europe. RESULTS A total of 17 104 patients' cases were included: Spain, 1186; UK and Ireland, 6653; northern Europe, 6097; and central Europe, 3168. Spain saw more emergencies related to cocaine (48.4%) and fewer related to opioids (12.4%) than the other areas. The Spanish patients were younger (32.2 years) on average than those in northern Europe and older than those in the UK and Ireland and central Europe. Fewer patients were women in Spain (21.9%) than in northern or central Europe. Fewer arrived in ambulances in Spain (70.0%) than in the UK and Ireland or northern Europe. The Spanish EDs recorded the temperature and respiratory frequency of fewer patients (29.8% and 30.3%, respectively). Clinical signs differed between geographical areas attributable to differences in drug-use patterns. In Spain, naloxone was used by fewer patients (9.6%) than in the UK and Ireland and northern Europe, and flumazenil was used by more patients (5.6%) than in other areas. Spain saw lower percentages of admissions (4.6%) and patients who left without an ED discharge (6.2%) in comparison with other areas. Mortality rates in the Spanish EDs (0.4%) and after discharge from them (0.7%) were higher than in northern Europe. CONCLUSION The characteristics of emergencies related to recreational drug abuse registered by the Spanish EDs were differed from those registered in other parts of Europe due to different patterns of drug use. We also detected differences between the Spanish and other European EDs with respect to examinations or tests performed, treatment given, and discharge disposition.

Abstract
Different groups of children were compared on sentence verification tasks. The children were either academically, musically or artistically gifted, and there were two forms of the task. In one, a picture was followed by a sentence, and in another, one sentence was followed by another. Subjects had to decide as quickly as possible whether or not the second proposition logically confirmed the first. In the picture-sentence condition results from all groups could be fitted to the constituent comparison model for sentence verification proposed by Carpenter and Just (1975). For the sentence-sentence condition, however, the observed results diverged from those predicted by the model. The results are explained in terms of different degrees of linguistic processing capacities of the subjects, and they demonstrate the importance which verbal-logical congruence has for children. Artistically able children had difficulties in processing subject/object incongruence in sentence pairs whereas musically able children had more problems in processing above/below incongruence.

Abstract
Children were shown three visually displayed digits. The digits were exposed successively in three windows in such a way, that the left-to-right order never corresponded with the temporal-sequential order. When asked to recall or recognize the digits, normal children responded in terms of temporal order. Deaf, autistic and some subnormal children, recalled or recognized the spatial, i.e. the left-to-right order. The relationship between hearing and/or speech and the temporal ordering of visual displays is discussed.

Abstract
A core consideration in the care of Indigenous patients at the end of life is their place of death. Dying in community can be of paramount importance to Indigenous people. This paper reports the experiences of the Top End Palliative Care Service with respect to the barriers and solutions in the return of Indigenous patients to community for end-of-life care. These barriers include not only those associated with the significant distances and remoteness in the Northern Territory but, also, spiritual and cultural factors, which often influence healthcare delivery.

Abstract
Healthcare-associated infections (HCAIs) affect ∼4.5 million patients in Europe alone annually. With the ever-increasing number of 'multi-resistant' micro-organisms, alternative and more effective methods of environmental decontamination are being sought as an important component of infection prevention and control. One of these is the use of cold atmospheric pressure plasma (CAPP) systems with clinical applications in healthcare facilities. CAPPs have been shown to demonstrate antimicrobial, antifungal and antiviral properties and have been adopted for other uses in clinical medicine over the past decade. CAPPs vary in their physical and chemical nature depending on the plasma-generating mechanism (e.g. plasma jet, dielectric barrier discharge, etc.). CAPP systems produce a 'cocktail' of species including positive and negative ions, reactive atoms and molecules (e.g. atomic oxygen, ozone, superoxide and oxides of nitrogen), intense electric fields, and ultraviolet radiation (UV). The effects of these ions have been studied on micro-organisms, skin, blood, and DNA; thus, a range of possible applications of CAPPs has been identified, including surface decontamination, wound healing, biofilm removal, and even cancer therapy. Here we evaluate plasma devices, their applications, mode of action and their potential role specifically in combating HCAIs on clinical surfaces.

Abstract
This study collected an area-wide snapshot of current handover practice in psychiatric settings which included acute care units and community mental health centres. The study was conducted in two stages. Firstly, a questionnaire was sent to all clinical mental health staff within an area-wide health service regarding normal handover procedures and processes. The second part of the study used non-participant observers to evaluate actual handovers in inpatient and community settings. Of the 1125 surveys distributed in stage one, 380 (34%) were returned completed. Of the 40 handovers observed in stage two in which 637 patients were discussed, 40% included at least one consultant psychiatrist or registrar as a participant. Almost all the handovers were completed face-to-face in a specific location with a set time and duration. Eighty-six per cent of respondents reported that deteriorating patients were escalated for rapid response. The results of the survey and structured observations support the issues emerging from the literature from medical, surgical and clinical team handovers. Additionally, the issue of identifiers for deterioration of a psychiatric patient emerged as an area worthy of further investigation and incorporation into clinical handover education and training for psychiatric services.

Abstract
A selective and sensitive method for the analysis of Miconazole and its associated impurities is developed. The separation is carried out using a Thermo Scientific Hypersil Gold C18 Column (50 mm x 4.6 mm i.d., 1.9 µm particle size) with a mobile phase of acetonitrile-methanol-ammonium acetate (1.5 w/v) (30:32:38 v/v) at a flow rate of 2.5 mL/min and UV detection at 235 nm. The method is validated according to ICH guidelines with respect to precision, accuracy, linearity, specificity, robustness, and limits of detection and quantification. All parameters examined are found to be well within the stated guidelines. Naturally aged samples are also tested to determine sample stability. A profile of sample and impurity breakdown was presented. The analysis time was more than halved from just under 20 min (the current European Pharmacopeia Method) to under 8 min (developed method) and the method is applicable for assay and related substance determination.

Abstract
The use of body mass index (BMI) for the diagnosis of obesity has limitations, especially when comparing ethnic groups with different body proportions. The aim of this prospective study was to compare maternal body composition in early pregnancy between Caucasian Irish and Indian women. A total of 81 Indian women and 81 Irish Caucasian women were matched for age, parity and BMI. Maternal weight and height were measured, and body composition analysed using bioelectrical impedance. The Irish women were taller and weighed more than the Indian women (p<0.001). At any given BMI, the Indian women had a higher total body fat percentage, visceral fat level and high fat percentage than the Irish women (p=0.024, 0.001 and 0.001, respectively). Our findings suggest that lower BMI cut-offs should be used for screening for gestational diabetes mellitus in Indian women attending our antenatal services.

Abstract
GeneSigDB (http://www.genesigdb.org or http://compbio.dfci.harvard.edu/genesigdb/) is a database of gene signatures that have been extracted and manually curated from the published literature. It provides a standardized resource of published prognostic, diagnostic and other gene signatures of cancer and related disease to the community so they can compare the predictive power of gene signatures or use these in gene set enrichment analysis. Since GeneSigDB release 1.0, we have expanded from 575 to 3515 gene signatures, which were collected and transcribed from 1604 published articles largely focused on gene expression in cancer, stem cells, immune cells, development and lung disease. We have made substantial upgrades to the GeneSigDB website to improve accessibility and usability, including adding a tag cloud browse function, facetted navigation and a 'basket' feature to store genes or gene signatures of interest. Users can analyze GeneSigDB gene signatures, or upload their own gene list, to identify gene signatures with significant gene overlap and results can be viewed on a dynamic editable heatmap that can be downloaded as a publication quality image. All data in GeneSigDB can be downloaded in numerous formats including .gmt file format for gene set enrichment analysis or as a R/Bioconductor data file. GeneSigDB is available from http://www.genesigdb.org.

Abstract
Appropriate nutrition in pregnancy is fundamental for maternal and fetal health, and the long-term physiological wellbeing of the offspring. We aimed to determine whether a sample of pregnant women met the national guidelines for healthy eating during pregnancy, and to examine if compliance differs when analysed by Body Mass Index (BMI) category. Subjects completed a 24-hr dietary recall, and had their BMI calculated. The mean age was 27.8 years. The mean BMI was 25.1 kg/m2, with 32 (31.7%) subjects overweight and 14 (13.9%) obese based on BMI category. Although the majority of subjects thought that they had a healthy diet, less than half met the recommended guidelines for each individual food group with achievement of the dairy group being particularly low. Achievement of food group recommendations was not influenced by BMI category. Public health messages on healthy eating guidelines need to be clearly communicated to pregnant women.

Development of a real time monitor and multivariate method for long term diagnostics of atmospheric pressure dielectric barrier discharges: application to He, He/N2, and He/O2 discharges.

Abstract
In this paper we present the development and application of a real time atmospheric pressure discharge monitoring diagnostic. The software based diagnostic is designed to extract latent electrical and optical information associated with the operation of an atmospheric pressure dielectric barrier discharge (APDBD) over long time scales. Given that little is known about long term temporal effects in such discharges, the diagnostic methodology is applied to the monitoring of an APDBD in helium and helium with both 0.1% nitrogen and 0.1% oxygen gas admixtures over periods of tens of minutes. Given the large datasets associated with the experiments, it is shown that this process is much expedited through the novel application of multivariate correlations between the electrical and optical parameters of the corresponding chemistries which, in turn, facilitates comparisons between each individual chemistry also. The results of these studies show that the electrical and optical parameters of the discharge in helium and upon the addition of gas admixtures evolve over time scales far longer than the gas residence time and have been compared to current modelling works. It is envisaged that the diagnostic together with the application of multivariate correlations will be applied to rapid system identification and prototyping in both experimental and industrial APDBD systems in the future.

Abstract
This retrospective cross-sectional study examined if the white cell count (WCC) is increased in women with polycystic ovary syndrome (PCOS) and if so, is it due to PCOS or to the associated obesity? Body mass index (BMI) was calculated and body composition was measured using bioelectrical impedance analysis. Of the 113 women studied, 36 had PCOS and 77 did not. The mean WCC was higher in the PCOS group compared with the non-PCOS group (8.9 × 10(9)/l vs 7.4 × 10(9)/l p = 0.002). This increase was due to a higher neutrophil count (5.6 × 10(9)/l vs 4.3 × 10(9)/l; p = 0.003). There was a leucocytosis (WCC >11 × 10(9)/l) present in 19% of the PCOS group compared with 1% in the non-PCOS group (p < 0.001). The neutrophil count was abnormally high (>7.7 × 10(9)/l) in 14% of the PCOS group compared with 4% in the non-PCOS group (p < 0.001). On regression analysis, however, the only independent variable which explained both the increased WCC and the increased neutrophil count was PCOS. We found that PCOS is associated with an increased WCC due to increased neutrophils, which supports the evidence that PCOS is associated with low-grade inflammation. The increase appears to be due to the underlying PCOS, and not to the increased adiposity associated with PCOS.

Abstract
Children in care in Ireland have increased by 27% in the last decade. This population is recognized to be among the most vulnerable. This study aims to describe their placement histories, service use and mental health needs. Data was obtained on 174 children (56.5% of eligible sample) with a mean age of 10.83 (SD = 5.04). 114 (65.5%) were in care for three years or more. 29 (16.7%) did not have a SW and 49 (37.7%) had no GP 50 (28.7%) were attending CAMHS. Long term care, frequent placement changes and residential setting were significantly related with poorer outcomes and increased MH contact. Given the increase in numbers in care and the overall decrease in resource allocation to health and social care, individual care planning and prioritizing of resources are essential.

HIVBrainSeqDB: a database of annotated HIV envelope sequences from brain and other anatomical sites. AIDS Res Ther 2010; 7:43.

Abstract
Background The population of HIV replicating within a host consists of independently evolving and interacting sub-populations that can be genetically distinct within anatomical compartments. HIV replicating within the brain causes neurocognitive disorders in up to 20-30% of infected individuals and is a viral sanctuary site for the development of drug resistance. The primary determinant of HIV neurotropism is macrophage tropism, which is primarily determined by the viral envelope (env) gene. However, studies of genetic aspects of HIV replicating in the brain are hindered because existing repositories of HIV sequences are not focused on neurotropic virus nor annotated with neurocognitive and neuropathological status. To address this need, we constructed the HIV Brain Sequence Database. Results The HIV Brain Sequence Database is a public database of HIV envelope sequences, directly sequenced from brain and other tissues from the same patients. Sequences are annotated with clinical data including viral load, CD4 count, antiretroviral status, neurocognitive impairment, and neuropathological diagnosis, all curated from the original publication. Tissue source is coded using an anatomical ontology, the Foundational Model of Anatomy, to capture the maximum level of detail available, while maintaining ontological relationships between tissues and their subparts. 44 tissue types are represented within the database, grouped into 4 categories: (i) brain, brainstem, and spinal cord; (ii) meninges, choroid plexus, and CSF; (iii) blood and lymphoid; and (iv) other (bone marrow, colon, lung, liver, etc). Patient coding is correlated across studies, allowing sequences from the same patient to be grouped to increase statistical power. Using Cytoscape, we visualized relationships between studies, patients and sequences, illustrating interconnections between studies and the varying depth of sequencing, patient number, and tissue representation across studies. Currently, the database contains 2517 envelope sequences from 90 patients, obtained from 22 published studies. 1272 sequences are from brain; the remaining 1245 are from blood, lymph node, spleen, bone marrow, colon, lung and other non-brain tissues. The database interface utilizes a faceted interface, allowing real-time combination of multiple search parameters to assemble a meta-dataset, which can be downloaded for further analysis. Conclusions This online resource, which is publicly available at http://www.HIVBrainSeqDB.org, will greatly facilitate analysis of the genetic aspects of HIV macrophage tropism, HIV compartmentalization and evolution within the brain and other tissue reservoirs, and the relationship of these findings to HIV-associated neurological disorders and other clinical consequences of HIV infection.

Abstract
OBJECTIVE To provide clinically relevant evidence-based recommendations for the management of bipolar disorder in adults that are informative, easy to assimilate and facilitate clinical decision-making. METHOD A comprehensive literature review of over 500 articles was undertaken using electronic database search engines (e.g. MEDLINE, PsychINFO and Cochrane reviews). In addition articles, book chapters and other literature known to the authors were reviewed. The findings were then formulated into a set of recommendations that were developed by a multidisciplinary team of clinicians who routinely deal with mood disorders. These preliminary recommendations underwent extensive consultative review by a broader advisory panel that included experts in the field, clinical staff and patient representatives. RESULTS The clinical practice recommendations for bipolar disorder (bipolar CPR) summarise evidence-based treatments and provide a synopsis of recommendations relating to each phase of the illness. They are designed for clinical use and have therefore been presented succinctly in an innovative and engaging manner that is clear and informative. CONCLUSION These up-to-date recommendations provide an evidence-based framework that incorporates clinical wisdom and consideration of individual factors in the management of bipolar disorder. Further, the novel style and practical approach should promote their uptake and implementation.

Abstract
The development of a handheld single and triple chamber atmospheric pressure coaxial dielectric barrier discharge driven by Flyback circuitry for helium and argon discharges is described. The Flyback uses external metal-oxide-semiconductor field-effect transistor power switching technology and the transformer operates in the continuous current mode to convert a continuous dc power of 10-33 W to generate a 1.2-1.6 kV 3.5 micros pulse. An argon discharge breakdown voltage of approximately 768 V is measured. With a 50 kHz, pulse repetition rate and an argon flow rate of 0.5-10 argon slm (slm denotes standard liters per minute), the electrical power density deposited in the volume discharge increases linearly at a rate of 75+/-20% mW/cm(3) per 1 slm of gas. Electrical power transfer efficiency between the secondary Flyback coil and the discharge volume increases from 0.1% to 0.65%. Neutral argon gas forced convection analysis yields a similar energy loss rate to the electrical discharge process. Optical emission spectroscopy studies of the expanding discharge plume into ambient air reveal that the air climatically controls the plume chemistry to produce an abundance of neutral argon atoms and molecular nitrogen.

Alcohol--how much is too much? IRISH MEDICAL JOURNAL 2008; 101:200-202. [PMID: 18807807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/26/2023]
Abstract
The aims of this study were to examine perceptions of what a sample of students and graduates consider an excessive alcohol intake to be and it's effect on their health. 115 University College Cork (UCC) students and 133 UCC graduates were questioned about their opinions of an acceptable weekly intake of alcohol. The results reveal dramatic changes in drinking habits over recent decades. Students began drinking earlier than graduates and are far more accepting of greater amounts of alcohol being consumed. The student's average opinion of what constituted an excessive weekly alcohol intake was 26.5 units of alcohol/week whereas the graduates felt over 18 units/week was too much. We concluded that even amongst these highly educated cohorts there is a low level of awareness of safe limits of alcohol consumption.

Abstract
The oil from the pumpkin (Cucurbita pepo) seed is claimed to be useful in the management of benign prostatic hyperplasia. This investigation seeks to examine the effect of pumpkin seed oil on testosterone-induced hyperplasia of the prostate of rats. Hyperplasia was induced by subcutaneous administration of testosterone (0.3 mg/100 g of body weight) for 20 days. Simultaneous oral administration of either pumpkin seed oil (2.0 and 4.0 mg/100 g of body weight) or corn oil (vehicle) was also given for 20 days. The weights of the rats were recorded weekly, and the influence of testosterone and pumpkin seed oil on the weight gain of the rats was examined. On day 21, rats were sacrificed, and the prostate was removed, cleaned, and weighed. The prostate size ratio (prostate weight/rat body weight) was then calculated. Neither testosterone nor pumpkin seed oil had any significant influence on the weight gain of the rats. Testosterone significantly increased prostate size ratio (P < .05), and this induced increase was inhibited in rats fed with pumpkin seed oil at 2.0 mg/100 g of body weight. The protective effect of pumpkin seed oil was significant at the higher pumpkin seed oil dose (P < .02). We conclude pumpkin seed oil can inhibit testosterone-induced hyperplasia of the prostate and therefore may be beneficial in the management of benign prostatic hyperplasia.

Abstract
BACKGROUND Tricyclic antidepressant poisoning is often associated with significant cardiovascular and central nervous system toxicity. Effective treatment includes the use of appropriate gastric decontamination techniques, the administration of sodium bicarbonate, and meticulous supportive care. Tricylcic antidepressant toxicity typically lasts 24-48 hours following a significant overdose. CASE REPORT We describe a case of tricyclic antidepressant poisoning where significant clinical toxicity (QRS prolongation, metabolic acidosis) was observed for up to 4 days following ingestion of a modified-release preparation of amitriptyline. Successful patient recovery was associated with the use of multidose activated charcoal and repeated administration of intravenous sodium bicarbonate. CONCLUSIONS Clinicians should be aware of the potential for prolonged tricyclic toxicity in patients who have ingested modified-release amitriptyline in overdose. Gastric decontamination techniques such as multidose activated charcoal and whole bowel irrigation should be considered where there is evidence of ongoing tricyclic antidepressant absorption or clinical toxicity following ingestion of a modified-release preparation. These interventions may be indicated for prolonged periods (greater than 36 hours) post ingestion.

Abstract
OBJECTIVES Single dose activated charcoal (SDAC) may be an effective method of gastric decontamination when administered to patients within an hour of drug overdose. However, few patients who may benefit from this treatment attend an emergency department within this timeframe. The authors sought to determine the current attitudes of ambulance NHS trusts to recent recommendations that the administration of SDAC should be considered as a prehospital therapy. METHODS A postal questionnaire was used to determine the current level of use of prehospital activated charcoal by ambulance NHS trusts, the incidence of associated complications, and barriers preventing the routine use of prehospital SDAC. RESULTS A completed questionnaire was returned by 36 of the 39 ambulance NHS trusts in the UK (response rate 92%). Currently none of the trusts that responded to the questionnaire provides prehospital SDAC as an intervention. The most common barriers to the provision of prehospital SDAC are the current lack of evidence in the medical literature proving it is effective in improving patient outcome and the lack of a recognised protocol for its administration. Other issues included concerns regarding potential complications, ambulance turnaround times, lack of availability of SDAC, and lack of funding. CONCLUSIONS A lack of published evidence proving efficacy remains the most important factor in preventing the routine administration of SDAC to appropriate patients in the prehospital environment. Further research in this setting is required to determine the usefulness of this therapy.

Abstract
OBJECTIVES To assess whether initial patient consult by senior clinicians reduces numbers of patients waiting to be seen as an indirect measure of waiting time throughout the emergency department (ED). METHODS An emergency medicine consultant and a senior ED nurse (G or F grade), known as the IMPACT team, staffed the triage area for four periods of four hours per week, Monday to Friday between 9 am to 5 pm for three months between December 2001 and February 2002 when staffing levels permitted. Patients normally triaged by a nurse in this area instead had an early consultation with the IMPACT team. Data were collected prospectively on all patients seen by the IMPACT team. The number of patients waiting to be seen (for triage, in majors and in minors) was assessed every two hours during the IMPACT sessions and at corresponding times when no IMPACT team was operational. RESULTS There was an overall reduction in the number of patients waiting to be seen in the department from 18.3 to 5.5 (p<0.0001) at formal two hourly assessments. The largest difference was seen in minors. Of the patients seen at triage by the IMPACT team, 48.9% were discharged home immediately after assessment and treatment. With the IMPACT team present, no patient waited more than four hours for initial clinical consult. CONCLUSIONS By using a senior clinical team for initial patient consultation, the numbers of patients waiting fell dramatically throughout the ED. Many patients can be effectively treated and discharged after initial consult by the IMPACT team.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for the management of rheumatological disorders, and as analgesics and antipyretics. Hepatotoxicity is an uncommon, but potentially lethal complication, which usually occurs within 12 weeks of starting therapy. It can occur with all NSAIDs, but appears to be more common with diclofenac and particularly sulindac. Female patients aged >50 years, with autoimmune disease, and those on other potentially hepatotoxic drugs, appear to be particularly susceptible. Liver function test abnormalities generally settle within 4-6 weeks of stopping the causative drug. However, some patients may develop acute liver failure and successful orthotopic liver transplantation may be undertaken in such patients. Recent in vitro animal studies have shown that the mechanism of diclofenac toxicity relates both to impairment of ATP synthesis by mitochondria, and to production of active metabolites, particularly n,5-dihydroxydiclofenac, which causes direct cytotoxicity. Mitochondrial permeability transition (MPT) has also been shown to be important in diclofenac-induced liver injury, resulting in generation of reactive oxygen species, mitochondrial swelling and oxidation of NADP and protein thiols. Physicians and hepatologists must be vigilant to the hepatotoxic potential of any NSAID, as increased awareness, surveillance and reporting of these events will lead to a better understanding of the risk factors and the pathophysiology of NSAID-related hepatotoxicity.

Abstract
The objective of this study was to compare the expressed confidence of senior house officers (SHOs) at performing practical medical procedures before and after working in an accident and emergency (A&E) post. The extent of formal teaching of these skills and opportunity for independent performance of them was also assessed. A postal questionnaire was sent to all SHOs completing an A&E post in the Trent region of the United Kingdom. Doctors were asked to grade their subjective confidence at performing listed practical skills before and after working in A&E. Eighty-four replies from 120 questionnaires were received (70% response rate). There was a significant improvement in confidence ( <0.0001) for all the skills studied after working in A&E. The proportion of doctors who received instruction varied for each of the skills. The expressed confidence of SHOs in performing practical procedures improved dramatically after working in A&E. Although remaining a valuable 'apprenticeship' for junior doctors, structured training is inadequate in the accident and emergency SHO post.

Abstract
OBJECTIVE To describe the current use of nutritional supplements and their contribution to micronutrient intakes in a representative sample of Irish adults, to evaluate the impact of supplement use on the adequacy of micronutrient intakes and to assess the risk to supplement users of exceeding tolerable upper intake levels (UL). STUDY DESIGN AND SUBJECTS Food intake data were collected in 1379 (662 male and 717 female) randomly selected Irish adults aged 18 to 64 years using a 7-day food diary. The current use of nutritional supplements was assessed using a self-administered questionnaire and respondents entered each supplement as it was consumed into the food diary. RESULTS Twenty-three per cent of respondents regularly used nutritional supplements. Twice as many women used supplements as men. The intakes of micronutrients were significantly higher (P<0.001) in supplement users than in non-users. Micronutrient intakes from food sources were similar in male users and non-users of supplements, but were significantly higher (P<0.01) in female users, by 3 to 13%, for Fe, Mg, Mn, vitamins C and E and niacin than in non-users. The percentage of female users between 18 and 50 years who had mean Fe intakes below the average requirement (AR) (10 mg) decreased from 50 to 25 when the contribution from supplements was included. The use of supplements reduced the percentage of men who had mean intakes below the AR for Zn from 19 to 13, for riboflavin from 14 to 6 and for vitamin A from 20 to 5, and reduced the percentage of women with intakes below the AR for Ca from 23 to 16 and for riboflavin from 23 to 14. Twenty-one women out of 80 aged between 18 and 50 years, who consumed supplemental folate, achieved the intake of 600 microg recommended to prevent neural tube defects. Twenty-two per cent of the women who took iron and 15% of the women who took vitamin B6 in supplemental form had mean daily intakes that exceeded that UL for these nutrients. Supplement users did not exceed the UL for the other micronutrients. CONCLUSIONS Supplementation appears to be beneficial in promoting adequate intakes of some micronutrients, particularly Fe and folate in women aged 18-50 years and vitamin A in men. There appears to be little risk to supplement users of experiencing adverse side effects due to excessive intakes of micronutrients.
