Retaining dermatology patients in primary care through dialogue with secondary care providers: A service evaluation. Ann Dermatol Venereol 2024; 151:103248. [PMID: 38513422 DOI: 10.1016/j.annder.2024.103248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 06/28/2023] [Accepted: 11/07/2023] [Indexed: 03/23/2024]
Abstract
BACKGROUND There are long patient waiting lists for specialist care. A dermatology dialogue service between primary and secondary care (DDPS) was developed in eastern England. Primary care referrers uploaded patient images of skin conditions for review by and dialogue with consultant dermatologists in an attempt to retain patients in primary care rather than refer them to secondary care. METHODS Evaluation of service performance against specific targets, including reduction in secondary care waiting list growth over the period April 2021-March 2022 inclusive. Service activity was summarized in terms of speed of resolution, case numbers, and dispositions. Clinician and patient satisfaction were assessed using structured questionnaires. Actual numbers of new referrals were compared to projections based on historical data. Waiting list growth was compared to other specialties and other commissioning areas. Waiting times to initial treatment were monitored. RESULTS Over 3300 patients were enrolled and > 90% of dialogues were resolved within 36 hours. Clinician and patient satisfaction were high. Frequently asked questions and conditions were highlighted by dermatologists to design and deliver an educational event for primary care clinicians that was well received. Waiting list growth for dermatology patients in the commissioning area was smaller than for other major specialties, and generally smaller than growth for dermatology waiting lists commissioned by other NHS commissioners. There was no negative impact on the urgent priority (cancer pathway) waiting list. CONCLUSION The DDPS was satisfactory for clinicians and patients and coincided with lower growth in dermatology waiting lists than might otherwise have been expected.

Public perspectives on inequality and mental health: A peer research study. Health Expect 2023; 27:e13868. [PMID: 37786331 PMCID: PMC10768865 DOI: 10.1111/hex.13868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 08/23/2023] [Accepted: 08/28/2023] [Indexed: 10/04/2023] Open
Abstract
INTRODUCTION Associations between structural inequalities and health are well established. However, there is limited work examining this link in relation to mental health, or that centres public perspectives. This study explores people's experience and sense-making of inequality in their daily lives, with particular consideration of impacts on mental health. METHODS We conducted a peer research study. Participants had to live in one of two London Boroughs and have an interest in inequalities and mental health. Using social media, newsletters, local organisations and our peer researchers' contacts, we recruited 30 participants who took photos representing their experience of inequality and discussed them during semi-structured interviews. Data were analysed using reflexive thematic analysis. RESULTS Three themes were identified in this study: (1) inequalities are unjust, multilayered and intertwined with mental health. Accounts demonstrated a deep understanding of inequalities and their link to mental health outcomes, describing inequalities as 'suffering' and 'not good for anyone'. Financial, housing, immigration and healthcare problems exacerbated poor mental health, with racism, gender-based violence and job loss also contributing factors for both poor mental health and experiences of inequality; (2) inequalities exclude and have far-reaching mental health consequences, impacting personal sense of belonging and perceived societal value and (3) moving forwards-addressing long-standing inequality and poor public mental health necessitated coping and resilience strategies that are often unacknowledged and undervalued by support systems. CONCLUSION Lived experience expertise was central in this study, creating an innovative methodological approach. To improve public mental health, we must address the everyday, painful structural inequalities experienced by many as commonplace and unfair. New policies and strategies must be found that involve communities, redistributing resources and power, building on a collective knowledge base, to coproduce actions combatting inequalities and improving population mental health. PATIENT OR PUBLIC CONTRIBUTION This study was peer-led, designed and carried out by researchers who had experiences of poor mental health. Six authors of the paper worked as peer researchers on this study.

Third international challenge to model the medium- to long-range transport of radioxenon to four Comprehensive Nuclear-Test-Ban Treaty monitoring stations. JOURNAL OF ENVIRONMENTAL RADIOACTIVITY 2022; 255:106968. [PMID: 36148707 DOI: 10.1016/j.jenvrad.2022.106968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 07/08/2022] [Accepted: 07/15/2022] [Indexed: 06/16/2023]
Abstract
In 2015 and 2016, atmospheric transport modeling challenges were conducted in the context of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) verification, however, with a more limited scope with respect to emission inventories, simulation period and number of relevant samples (i.e., those above the Minimum Detectable Concentration (MDC)) involved. Therefore, a more comprehensive atmospheric transport modeling challenge was organized in 2019. Stack release data of Xe-133 were provided by the Institut National des Radioéléments/IRE (Belgium) and the Canadian Nuclear Laboratories/CNL (Canada) and accounted for in the simulations over a three (mandatory) or six (optional) months period. Best estimate emissions of additional facilities (radiopharmaceutical production and nuclear research facilities, commercial reactors or relevant research reactors) of the Northern Hemisphere were included as well. Model results were compared with observed atmospheric activity concentrations at four International Monitoring System (IMS) stations located in Europe and North America with overall considerable influence of IRE and/or CNL emissions for evaluation of the participants' runs. Participants were prompted to work with controlled and harmonized model set-ups to make runs more comparable, but also to increase diversity. It was found that using the stack emissions of IRE and CNL with daily resolution does not lead to better results than disaggregating annual emissions of these two facilities taken from the literature if an overall score for all stations covering all valid observed samples is considered. A moderate benefit of roughly 10% is visible in statistical scores for samples influenced by IRE and/or CNL to at least 50% and there can be considerable benefit for individual samples. Effects of transport errors, not properly characterized remaining emitters and long IMS sampling times (12-24 h) undoubtedly are in contrast to and reduce the benefit of high-quality IRE and CNL stack data. Complementary best estimates for remaining emitters push the scores up by 18% compared to just considering IRE and CNL emissions alone. Despite the efforts undertaken the full multi-model ensemble built is highly redundant. An ensemble based on a few arbitrary runs is sufficient to model the Xe-133 background at the stations investigated. The effective ensemble size is below five. An optimized ensemble at each station has on average slightly higher skill compared to the full ensemble. However, the improvement (maximum of 20% and minimum of 3% in RMSE) in skill is likely being too small for being exploited for an independent period.

Abstract
Injuries to articular cartilage are frequently difficult to repair, in part because of the poor regenerative capacity of this tissue. To date, no successful system for complete regeneration of the most challenging cartilage defects has been demonstrated. The aim of this work was to develop functionalised hydrogels at the nanoscale by Layer-by-Layer (LbL) assembly to promote cartilage healing. Hydrogels, based on sodium alginate (NaAlg) and gelatin (G), were prepared by an external gelation method consisting of CaCl2 diffusion and genipin addition for G crosslinking. Successively, hydrogels were coated with G to obtain a positive charge on the surface, then functionalised by LbL assembly to create 16 nanolayers, based on poly(styrene sulfonate)/poly(allyl amine) (PSS/PAH), including a specific peptide sequence (CTATVHL) and transforming growth factors β1 (TGF-β1). Physico-chemical properties were evaluated by XPS, ATR-FTIR and rheological analyses while in vitro cytocompatibility was studied using bovine articular chondrocytes (BAC). XPS spectra showed N1s and S2p peaks, indicating that PAH and PSS have been introduced with success. ATR-FTIR indicated the specific PAH and PSS absorption peaks. Finally, the biomolecule incorporation influenced positively the processes of BAC adhesion and proliferation, and glycosamynoglycan secretion. The functionalised alginate-based hydrogels described here are ideally suited to chondral regeneration in terms of their integrity, stability, and cytocompatibility.

Maternal and fetal genetic contribution to gestational weight gain. Int J Obes (Lond) 2018; 42:775-784.

Abstract
BACKGROUND Clinical recommendations to limit gestational weight gain (GWG) imply high GWG is causally related to adverse outcomes in mother or offspring, but GWG is the sum of several inter-related complex phenotypes (maternal fat deposition and vascular expansion, placenta, amniotic fluid and fetal growth). Understanding the genetic contribution to GWG could help clarify the potential effect of its different components on maternal and offspring health. Here we explore the genetic contribution to total, early and late GWG. PARTICIPANTS AND METHODS A genome-wide association study was used to identify maternal and fetal variants contributing to GWG in up to 10 543 mothers and 16 317 offspring of European origin, with replication in 10 660 mothers and 7561 offspring. Additional analyses determined the proportion of variability in GWG from maternal and fetal common genetic variants and the overlap of established genome-wide significant variants for phenotypes relevant to GWG (for example, maternal body mass index (BMI) and glucose, birth weight). RESULTS Approximately 20% of the variability in GWG was tagged by common maternal genetic variants, and the fetal genome made a surprisingly minor contribution to explain variation in GWG. Variants near the pregnancy-specific beta-1 glycoprotein 5 (PSG5) gene reached genome-wide significance (P=1.71 × 10-8) for total GWG in the offspring genome, but did not replicate. Some established variants associated with increased BMI, fasting glucose and type 2 diabetes were associated with lower early, and higher later GWG. Maternal variants related to higher systolic blood pressure were related to lower late GWG. Established maternal and fetal birth weight variants were largely unrelated to GWG. CONCLUSIONS We found a modest contribution of maternal common variants to GWG and some overlap of maternal BMI, glucose and type 2 diabetes variants with GWG. These findings suggest that associations between GWG and later offspring/maternal outcomes may be due to the relationship of maternal BMI and diabetes with GWG.

Abstract
BACKGROUND Acid base alterations occur during laparoscopy with carbon dioxide insufflation. The purpose of this study was to investigate the effects of low tidal volume ventilation on acid base status during pneumoperitonium. MATERIALS AND METHODS 30 patients undergoing laparoscopic surgery under General Anaesthesia were ventilated with tidal volume of 6 ml/kg and respiratory rate of 12 breaths/minute. Arterial blood gas analysis was done before, during and after C02 pneumoperitoneum. Arterial haemoglobin oxygen saturation by pulse oximetry (SPO2) and EtC02 were monitored continuously throughout the laparoscopy. Respiratory adjustments were done for EtCO2 levels above 60mmHg or SPO2 below 92% or adverse haemodynamic changes. RESULTS low tidal volume ventilation during pneumoperitoneum resulted in a significant elevation in PaCO2 (p<0.001) and a fall of pH (p <0.001), ion bicarbonate (HCO3-) (p = 0.011), and base excess (ABE) (p <0.001). A correlation was found between the EtCO2 and PaCO2 during pneumoperitoneum. Oxygenation was well maintained during pneumoperitoneum. No ventilatory adjustments were instituted on any of the patients as they maintained EtCO2 below 60mmHg throughout pneumoperitoneum. CONCLUSION Ventilation with low tidal volume during pneumoperitoneum causes a mixed respiratory and metabolic acidosis. EtCO2 is still a good non-invasive monitor for estimation of PaCO2 during low tidal volume ventilation during pneumoperitoneum.

Abstract
OBJECTIVE Interleukin-1β (IL-1β) is involved in the up-regulation of matrix metalloproteinases (MMPs) leading to cartilage degradation. Cannabinoids are anti-inflammatory and reduce joint damage in animal models of arthritis. This study aimed to determine a mechanism whereby the synthetic cannabinoid WIN-55,212-2 mesylate (WIN-55) may inhibit cartilage degradation. METHODS Effects of WIN-55 were studied on IL-1β stimulated production of MMP-3 and -13 and their inhibitors TIMP-1 and -2 in human chondrocytes. Chondrocytes were obtained from articular cartilage of patients undergoing total knee replacement. Chondrocytes were grown in monolayer and 3D alginate bead cultures. Real-time polymerase chain reaction (PCR) was used to determine the gene expression of MMP-3, -13, TIMP-1 and -2 and Enzyme Linked Immunosorbent Assay (ELISA) to measure the amount of MMP-3 and MMP-13 protein released into media. Immunocytochemistry was used to investigate the expression of cannabinoid receptors in chondrocyte cultures. RESULTS Treatment with WIN-55 alone or in combination with IL-1β, decreased or abolished MMP-3, -13, TIMP-1 and -2 gene expression in human chondrocyte monolayer and alginate bead cultures in both a concentration and time dependent manner. WIN-55 treatment alone, and in combination with IL-1β, reduced MMP-3 and -13 protein production by chondrocytes cultured in alginate beads. Immunocytochemistry demonstrated the expression of cannabinoid receptors in chondrocyte cultures. CONCLUSION Cannabinoid WIN-55 can reduce both basal and IL-1β stimulated gene and protein expression of MMP-3 and -13. However WIN-55 also decreased basal levels of TIMP-1 and -2 mRNA. These actions of WIN-55 suggest a mechanism by which cannabinoids may act to prevent cartilage breakdown in arthritis.

Abstract
The Knowledge Network (www.knowledge.scot.nhs.uk) is Scotland's online knowledge service for health and social care. It is designed to support practitioners to apply knowledge in frontline delivery of care, helping to translate knowledge into better health-care outcomes through safe, effective, person-centred care. The Knowledge Network helps to combine the worlds of evidence-based practice and quality improvement by providing access to knowledge about the effectiveness of clinical interventions ('know-what') and knowledge about how to implement this knowledge to support individual patients in working health-care environments ('know-how'). An 'evidence and guidance' search enables clinicians to quickly access quality-assured evidence and best practice, while point of care and mobile solutions provide knowledge in actionable formats to embed in clinical workflow. This research-based knowledge is complemented by social networking services and improvement tools which support the capture and exchange of knowledge from experience, facilitating practice change and systems improvement. In these cases, the Knowledge Network supports key components of the knowledge-to-action cycle--acquiring, creating, sharing and disseminating knowledge to improve performance and innovate. It provides a vehicle for implementing the recommendations of the national Knowledge into Action review, which outlines a new national approach to embedding knowledge in frontline practice and systems improvement.

Abstract
Frequent atmospheric measurements of the anthropogenic compound methylchloroform that were made between 1978 and 1985 indicate that this species is continuing to increase significantly around the world. Reaction with the major atmospheric oxidant, the hydroxyl radical (OH), is the principal sink for this species. The observed mean trends for methylchloroform are 4.8, 5.4, 6.4, and 6.9 percent per year at Aldrigole (Ireland) and Cape Meares (Oregon), Ragged Point (Barbados), Point Matatula (American Samoa), and Cape Grim (Tasmania), respectively, from July 1978 to June 1985. These measured trends, combined with knowledge of industrial emissions, were used in an optimal estimation inversion scheme to deduce a globally averaged methylchloroform atmospheric lifetime of 6.3 (+ 1.2, -0.9) years (1sigma uncertainty) and a globally averaged tropospheric hydroxyl radical concentration of (7.7 +/- 1.4) x 10(5) radicals per cubic centimeter (1sigma uncertainty). These 7 years of gas chromatographic measurements, which comprise about 60,000 individual calibrated real-time air analyses, provide the most accurate estimates yet of the trends and lifetime of methylchloroform and of the global average for tropospheric hydroxyl radical levels. Accurate determination of hydroxyl radical levels is crucial to understanding global atmospheric chemical cycles and trends in the levels of trace gases such as methane.

Abstract
Naturally derived polymers have been extensively used in scaffold production for cartilage tissue engineering. The present work aims to evaluate and characterize extracellular matrix (ECM) formation in two types of chitosan-based scaffolds, using bovine articular chondrocytes (BACs). The influence of these scaffolds' porosity, as well as pore size and geometry, on the formation of cartilagineous tissue was studied. The effect of stirred conditions on ECM formation was also assessed. Chitosan-poly(butylene succinate) (CPBS) scaffolds were produced by compression moulding and salt leaching, using a blend of 50% of each material. Different porosities and pore size structures were obtained. BACs were seeded onto CPBS scaffolds using spinner flasks. Constructs were then transferred to the incubator, where half were cultured under stirred conditions, and the other half under static conditions for 4 weeks. Constructs were characterized by scanning electron microscopy, histology procedures, immunolocalization of collagen type I and collagen type II, and dimethylmethylene blue assay for glycosaminoglycan (GAG) quantification. Both materials showed good affinity for cell attachment. Cells colonized the entire scaffolds and were able to produce ECM. Large pores with random geometry improved proteoglycans and collagen type II production. However, that structure has the opposite effect on GAG production. Stirred culture conditions indicate enhancement of GAG production in both types of scaffold.

Abstract
UNLABELLED In this paper we focus on providing an alcohol screening and intervention service within maxillofacial surgery. Two trained nurses screened patients with alcohol-related facial injuries who attended maxillofacial outpatient clinics, and gave brief motivational interventions to those who had been drinking to a hazardous level. Patients were followed up at 3 and 12 months after the intervention. 195/249 patients (78%) drank to a hazardous level. One hundred and ninety-five patients received an intervention. Duration of intervention was between 5 and 65 minutes. Reasons for refusal to participate included lack of interest or time, and the main reason for exclusion was length of time since injury. The follow up rate was 103 (53%) at 3 months and 134 (69%) at 12 months. CONCLUSIONS The high level of hazardous drinking among people with facial trauma suggests a clear need for alcohol screening and intervention. It is feasible for nursing staff to deliver brief interventions in a busy maxillofacial trauma clinic.

Abstract
Low-friction surfaces are critical for efficient joint articulation. The tribological properties of articular cartilage have been studied extensively in native tissue and joints. Despite their importance, very few studies have examined the frictional properties of tissue-engineered cartilage. We have therefore reviewed the relationship between composition, structure and friction in tissue-engineered cartilage.

Abstract
BACKGROUND Short burst oxygen therapy (SBOT) is widely prescribed in the UK with little evidence of benefit. A study was performed to examine whether SBOT benefits patients when undertaking normal activities at home among those who already use it. METHODS Twenty-two patients with chronic obstructive pulmonary disease (COPD) were included in the study. All regularly used SBOT at home and claimed that it helps them. Each patient chose two daily living activities for which they used SBOT for relief of breathlessness. Patients were then randomised to use either an air or oxygen gas cylinder. At least 15 min later the same activity was performed using the other gas cylinder. The same process was then repeated for the second chosen activity. The main endpoints were subjective and objective times to recovery, analysed for each activity separately or taking the average over the two activities. A paired statistical analysis was performed. RESULTS All patients used SBOT with nasal prongs after exercise. Using the average recovery time over two activities for each patient, the mean objective recovery time was 38 s lower (95% CI -81 to +5) using oxygen and the mean subjective recovery time was 34 s lower (95% CI -69 to +2). Five patients were correctly able to distinguish oxygen from air after both activities and there was a suggestion that their recovery times were shorter than those who did not correctly identify the gases (91 s vs 20 s using objective recovery times, and 80 s vs 22 s using subjective recovery times), although this was a subgroup analysis based on only five patients with non-significant results. CONCLUSIONS There is some evidence that SBOT shortens recovery time after activities of daily living in a selected group of patients with COPD, but the effect is small. There appears to be a subgroup of patients who may benefit to a much greater degree.

A cartilage tissue engineering approach combining starch-polycaprolactone fibre mesh scaffolds with bovine articular chondrocytes. JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2007; 18:295-302. [PMID: 17323161 DOI: 10.1007/s10856-006-0692-7] [Citation(s) in RCA: 45] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2006] [Accepted: 09/25/2006] [Indexed: 05/14/2023]
Abstract
In the present work we originally tested the suitability of corn starch-polycaprolactone (SPCL) scaffolds for pursuing a cartilage tissue engineering approach. Bovine articular chondrocytes were seeded on SPCL scaffolds under dynamic conditions using spinner flasks (total of 4 scaffolds per spinner flask using cell suspensions of 0.5 x 10(6) cells/ml) and cultured under orbital agitation for a total of 6 weeks. Poly(glycolic acid) (PGA) non-woven scaffolds and bovine native articular cartilage were used as standard controls for the conducted experiments. PGA is a kind of standard in tissue engineering approaches and it was used as a control in that sense. The tissue engineered constructs were characterized at different time periods by scanning electron microscopy (SEM), hematoxylin-eosin (H&E) and toluidine blue stainings, immunolocalisation of collagen types I and II, and dimethylmethylene blue (DMB) assay for glycosaminoglycans (GAG) quantification assay. SEM results for SPCL constructs showed that the chondrocytes presented normal morphological features, with extensive cells presence at the surface of the support structures, and penetrating the scaffolds pores. These observations were further corroborated by H&E staining. Toluidine blue and immunohistochemistry exhibited extracellular matrix deposition throughout the 3D structure. Glycosaminoglycans, and collagen types I and II were detected. However, stronger staining for collagen type II was observed when compared to collagen type I. The PGA constructs presented similar features to SPCL at the end of the 6 weeks. PGA constructs exhibited higher amounts of matrix glycosaminoglycans when compared to the SPCL scaffolds. However, we also observed a lack of tissue in the central area of the PGA scaffolds. Reasons for these occurrences may include inefficient cells penetration, necrosis due to high cell densities, or necrosis related with acidic by-products degradation. Such situation was not detected in the SPCL scaffolds, indicating the much better biocompatibility of the starch based scaffolds.

Abstract
OBJECTIVE To evaluate cell cultures derived from intrasynovial nodules from a patient with primary synovial chondromatosis (PSC) for aberrant numbers/differentiation of osteochondroprogenitor cells. METHODS Cell cultures were established from PSC synovial nodules, or normal bovine or human osteoarthritis (OA) synovia (for comparison). Multi-lineage potential was determined using well-characterized in vitro culture systems to assess osteogenic, chondrogenic and adipogenic capability. RESULTS Primary PSC cell cultures were typically fibroblastic but contained islands of dense cell clusters/nodules, some of which were isolated and cultured separately [putative osteochondroprogenitris (pOCP) cultures]. OA synovial cultures had barely detectable levels of alkaline phosphatase (AP) that increased (0.006+/-0.008 to 0.141+/-0.000 nmol p-nitrophenol/min/cm(2)) with dexamethasone treatment. AP activity was higher in primary PSC cell cultures and further enhanced by dexamethasone (from 0.076+/-0.022 to 5.735+/-0.000 nmol p-nitrophenol/min/cm(2)). Histochemically, AP was localized as discreet areas within PSC cultures. No AP activity was detected histochemically in OA or normal bovine synovial cultures. The pOCP cultures had high basal AP (5.036+/-0.439 nmol p-nitrophenol/min/cm(2)) and spontaneously formed mineralized nodules, which increased in number under standard osteogenic conditions. Under chondrogenic conditions, micromass or pellet-cultured pOCP cells spontaneously synthesized a matrix containing glycosaminoglycans and collagen II. In adipogenic medium, the number of lipid-containing cells was increased. CONCLUSIONS Compared with cultures established from OA or normal synovia, cell cultures established from PSC synovial nodules were enriched in osteochondroprogenitors, which, unlike normal mesenchymal cells, differentiated along chondrogenic and osteogenic lineages in the absence of dexamethasone.

Abstract
OBJECTIVES This study investigated the relationship between a measure of positivity in illness, the Silver Lining Questionnaire (SLQ), and measures of personality and spirituality/religious beliefs as a way of determining whether positivity in illness is a delusion or existential growth. METHOD This is a cross-sectional study comparing response to the SLQ, to the Eysenck Personality Questionnaire (EPQ-R), breathlessness, illness type, and spiritual and religious beliefs in a final total sample of 194 respiratory outpatients. RESULTS The SLQ was associated positively with extraversion (r =.16, p<.05), unrelated to neuroticism (r =.11, n.s.) and repression (r =.10, n.s.) and was positively associated with spiritual and religious beliefs, F(2; 187) = 7.12, p < 001, as predicted by the existential growth but not the delusion interpretation. There was no relationship between positivity and age, r(194) =.09, n.s., or between positivity and gender t(192) = -1.27, n.s., and nor were there relationships with type of illness, F(4, 188) = 2.17, n.s., or breathlessness, F (5, 173) = 0.42, n.s. CONCLUSIONS The results suggest that positivity in illness is associated with existential growth, though the cross-sectional nature of the study precludes a conclusion of causal direction. The non-significant correlation between the SLQ and neuroticism is in the opposite direction predicted by the delusion explanation, but the non-significant relationship between the SLQ and repression is in the predicted direction. We cannot rule out the possibility that some positivity is delusion.

Abstract
BACKGROUND The British Thoracic Society (BTS) guidelines have not been examined collectively for their impact on chronic obstructive pulmonary disease (COPD). Whether intensive outpatient follow up of COPD patients after acute admission, using these guidelines, improved quality of life compared to the "usual practice" of primary care follow up was investigated. METHODS Altogether 103 patients with a new diagnosis of COPD were admitted and screened over a four year period. Seventy patients were excluded because of another dominant medical condition or a mandatory requirement for intervention. Patients were randomised to regular primary care (control group, n = 15) or chest clinic follow up (intervention group, n = 10). Spirometry, oxygen saturation, St George's Respiratory Questionnaire (SGRQ), and Short Form 36 questionnaire were measured at baseline and six months. The intervention group was reviewed at least four times in the six month period and received spirometry, ambulatory oxygen assessment, smoking cessation advice, nebuliser assessment, a steroid trial, advice about nutrition/exercise, and introduction to a patient support group. RESULTS There was no significant difference between baseline measurements in the two groups. There was a significant mean (SD) improvement in the SGRQ symptom score from baseline to six months in the intervention group [20.98 (20.36)] compared with the controls [0.23 (12.55)] (p = 0.004). At six months the SGRQ symptom score, impact score, and total score was significantly better in the intervention than the control group (p = 0.01, 0.02, and 0.02). CONCLUSION Aggressive implementation of BTS guidelines after initial hospitalisation may improve respiratory health specific quality of life scores in patients with COPD. Larger studies are needed to confirm this finding.

Abstract
BACKGROUND Evidence for improved exercise tolerance or relief of breathlessness by short term use of oxygen before or after exercise in patients with chronic obstructive pulmonary disease (COPD) is scant, and guidelines for this treatment are lacking despite widespread provision in the UK. METHODS The effect of oxygenation either before or after exercise on perception of breathlessness and walk distance was studied in a group of patients with moderate to severe COPD (mean forced expiratory volume in 1 second (FEV(1)) 34% of predicted, mean 6 minute walk distance on air 283 m), all of whom desaturated by at least 4% on submaximal exercise. Oxygen (28%) or air was delivered double blind and in random order, either for 5 minutes before a standard 6 minute walk test (n=34) or for 5 minutes following the end of the test (n=18). Exercise tolerance was measured as the distance achieved and breathlessness was assessed using visual analogue scales (VAS) which were scored before and after exercise and during recovery. RESULTS No increase in mean walk distance after oxygen (288 v 283 m) and no improvement in mean breathlessness scores (58 v 54 mm) or recovery times occurred with oxygen taken either before (177 v 184 seconds) or after exercise (182 v 151 seconds). CONCLUSIONS This group of patients with COPD derived no physiological or symptomatic benefit from oxygen breathed for short periods before or after submaximal exercise. Domiciliary oxygen should only be prescribed for such patients if they have shown objective evidence of benefit on exercise testing.

Abstract
The effects of devitrification of an ionomer glass with a molar composition 4.5SiO(2).3Al(2)O(3).1.5P(2)O(5).3CaO.2CaF(2) on cement formation and in vitro biocompatibility were investigated. Differential thermal analysis was used to study the phase evolution in the glass, and to determine the heat treatments for production of glass-ceramics. X-ray diffraction patterns from glass frit heat-treated at 750 degrees C for 2h contained peaks corresponding to apatite (JCPDS 15-876), whereas for samples heat-treated at 950 degrees C for 2h apatite and mullite (JCPDS 15-776) were the major phases detected. Transmission electron microscopy (TEM) confirmed that apatite and apatite-mullite phases were present after heat treatments at 750 degrees C and 950 degrees C respectively. Glass and glass-ceramics were ground to prepare <45microm powders and glass ionomer cements were produced using a ratio of 1g powder: 0.2g PAA: 0.3g 10% m/v tartaric acid solution in water. In vitro biocompatibility was evaluated using cultured rat osteosarcoma (ROS) cells. Scanning electron microscopy (SEM) showed that cells colonised the surfaces of cements prepared using untreated ionomer glass and glass crystallised to form apatite (750 degrees C/2h). However, quantitative evaluation using MTT and total protein assays indicated that more cell growth occurred in the presence of cements prepared using ionomer glasses crystallised to apatite than cements prepared using untreated glass. The least cell growth and respiratory activity was observed on cements made with crystallised glass containing both apatite and mullite. It was concluded that the controlled devitrification of ionomer glasses could be used to produce GIC bone cements with improved biocompatibility.

Abstract
OBJECTIVES Chronic methicillin-resistant Staphylococcus aureus (MRSA) infections in debilitated patients are difficult to treat. We studied the clinical efficacy and safety of an oral streptogramin, pristinamycin, for these patients. PATIENTS AND METHODS Patients were admitted consecutively to receive pristinamycin, usually with doxycycline, for 7-21 days. Fifty-six patients (average age 75 years) from hospital and community were treated for skin, soft tissue, chest and other infections. RESULTS The overall clinical response rate was 39 of 53 patients (74%; 95% CI: 60%, 85%) cured or substantially improved, from 53 of 56 (95%) patients clinically and 49 of 56 (87.5%) patients bacteriologically evaluable. Toxic effects comprised gastrointestinal disturbances in eight patients (14%) and one (2%) possible skin rash. CONCLUSION This study suggests that oral streptogramins may be useful in the management of debilitated patients with MRSA infections.

Abstract
BACKGROUND Anticipating the prospect of specific treatment, we studied a large group of Australians with Fabry's disease. AIMS We aimed to: (i) document the clinical features of Fabry's disease in Australian patients, (ii) test the hypothesis that clinical features vary with specific mutation and blood group and (iii) assess small-fibre peripheral nerve function. METHODS A questionnaire was forwarded to all Australian patients known to us. Patients were invited to attend for clinical, renal cardiac, ophthalmological and neurological assessment. RESULTS Sixty-seven patients (29 men and 38 women) from 18 families participated. Diagnosis in index cases was delayed by > or = 10 years in nearly all families. Common clinical features are: (i) episodic acroparaesthesia (100% of hemizygotes; 53% of heterozygotes), (ii) anhydrosis (93%; 1%), (iii) characteristic rash (93%; 13%), (iv) renal disease (69%; 21%), (v) ischaemic heart disease (28%; 26%), (vi) palpitations (62%; 29%), (vii) mitral valve murmurs (37%; 23%) and (viii) premature cerebrovascular disease (31%; 5%). Ophthalmic findings of cornea verticillata (96%; 76%) and anterior cataract (48%; 14%) were common. Findings were variable within and between families. In women, anhydrosis reliably predicts the presence of significant Fabry's renal disease. Small nerve fibre testing using quantitative sensory testing was clearly abnormal in 95% of male patients, and in those female patients with paraesthesiae. CONCLUSIONS Symptoms of anhydrosis, acroparaesthesiae, rash and renal disease suggest diagnosis of Fabry's. Women are commonly symptomatic, and the advent of therapy highlights the practical advantage of earlier diagnosis.

Abstract
There is some controversy amongst respiratory physicians over the value of domiciliary nebuliser use for chronic lung conditions. Most recommendations for assessment of suitability for this form of treatment rely upon response to lung function tests and reported improvements in exercise ability. Relatively little emphasis has been placed upon the patient view of this therapy. This survey examined the subjective views of patients receiving domiciliary nebulisers regarding this treatment. A postal questionnaire was sent to 82 patients using home nebuliser treatment provided by the respiratory clinic at Whipps Cross University Hospital, London. It consisted of 29 structured questions covering topics of well-being and symptom control, self-confidence, dependency, time and technical issues, as well as side effects and compliance. Most patients surveyed had chronic obstructive lung disease. For almost all sections of the questionnaire patients reported overwhelmingly that the benefits of using a nebuliser outweighed potential disadvantages. The main perceived advantages werethe ability for patients themselves to control symptoms and to be less dependent on General Practitioners, hospitals and carers. Compliance was generally excellent, and the reported side effects were minor and relatively infrequent. The results strongly support the view that nebulisers are helpful in managing chronic lung disease in the community with benefit to patient well-being and potential health cost savings.
