Abstract
OBJECTIVES To evaluate the impact of treatment provided by a Crisis Resolution Home Treatment Team (CRHTT) in terms of preventing hospital admission, impact on service user's symptoms and overall functioning, as well as service user's satisfaction with the service. Secondary objectives were to evaluate the patient characteristics of those attending the CRHTT. METHODS All the service users treated by the CRHTT between 2016 and 2020 were included. Service users completed the Brief Psychiatric Rating Scale (BPRS), the Health of the Nation Outcome Scale (HoNOS), and the Client Satisfaction Questionnaire-version 8 (CSQ-8) before and after treatment by the CRHTT. Admission rates were compared between areas served by the CRHTT and control, before and after the introduction of the CRHTT, using two-way ANOVA. RESULTS Between 2016 and 2020, 1041 service users were treated by the service. Inpatient admissions in the areas served by the CRHTT fell by 38.5% after its introduction. There was a statistically significant interaction between CRHTT availability and time on admission rate, F (1,28) = 8.4, p = .007. BPRS scores were reduced significantly (p < .001), from a mean score of 32.01 before treatment to 24.64 after treatment. Mean HoNOS scores were 13.6 before and 9.1 after treatment (p < .001). Of the 1041 service users receiving the CSQ-8, only 180 returned it (17.3%). Service users' median responses were "very positive" to all eight items on the CSQ-8. CONCLUSIONS Although our study design has limitations this paper provides some support that CRHTT might be effective for the prevention of inpatient admission. The study also supports that CRHTT might be an effective option for the treatment of acute mental illness and crisis, although further research is needed in this area.

Abstract
OBJECTIVES The objective of this study was to assess the diagnostic performance of combined computerised tomography (CT) and positron emission tomography (PET) in mediastinal staging of surgical lung cancer based on data obtained from the prospective cohort of the Spanish Group for Video-Assisted Thoracic Surgery (GEVATS). METHODS A total of 2782 patients underwent surgery for primary lung carcinoma. We analysed diagnostic success in mediastinal lymph node staging (cN2) using CT and PET. Bivariate and multivariate analyses were performed of the factors involved in this success. The risk of unexpected pN2 disease was analysed for cases in which an invasive testing is recommended: cN1, the tumour centrally located or the tumour diameter >3 cm. RESULTS The overall success of CT together with PET was 82.9% with a positive predictive value of 0.21 and negative predictive value of 0.93. If the tumour was larger than 3 cm and for each unit increase in mediastinal SUVmax, the probability of success was lower with OR 0.59 (0.44-0.79) and 0.71 (0.66-0.75), respectively. In the video-assisted thoracic surgery (VATS) approach, the probability of success was higher with OR 2.04 (1.52-2.73). The risk of unexpected pN2 increased with the risk factors cN1, the tumour centrally located or the tumour diameter >3 cm: from 4.5% (0 factors) to 18.8% (3 factors) but did not differ significantly as a function of whether invasive testing was performed. CONCLUSIONS CT and PET together have a high negative predictive value. The overall success of the staging is lower in the case of tumours >3 cm and high mediastinal SUVmax, and it is higher when VATS is performed. The risk of unexpected pN2 is higher if the disease is cN1, the tumour centrally located or the tumour diameter >3 cm but does not vary significantly as a function of whether patients have undergone invasive testing.

Abstract
Abstract
Objective
In situations in which randomized experiments are impossible or unethical, propensity score matching offers a method to reduce bias on causal effect estimates (Thoemmes & Kim, 2011). In this study, we examined differences on the digital clock drawing test (dCDT; Souillard-Mandar et al., 2016) between individuals with idiopathic non-dementia Parkinson’s disease (PD) and matched controls.
Method
This study involved a retrospective analysis of two federally funded investigations (NSF-13-543; R01-NS082386). The sample included 261 participants (110 PD, 151 non-PD). Participants were matched according to demographic covariates, as well as measures of mood, comorbidity, and premorbid functioning. The PD group and matched controls were compared using logistic regression in a Bayesian framework, with projection predictive variable selection implemented to obtain a parsimonious model (Piironen, Paasiniemi, & Vehtari, 2018). All effects were standardized.
Results
Of 261 participants, 212 were matched using nearest neighbor matching (Figure 1). The final, parsimonious model included four variables from the dCDT: total strokes (command condition), total time (command condition), and area (command and copy conditions). While all effects were retained, positive to strong evidence was found for dCDT total time (βMedian = 0.91, βSD = 0.25, 95% CI [0.44, 1.42], Bayes factor [BF] = 97.80) and dCDT area (copy condition; βMedian = −0.52, βSD = 0.19, 95% CI [−0.90, −0.17], BF = 4.78).
Conclusions
Propensity scores can be employed in causal comparative studies to match control participants and reduce bias from nuisance covariates. Four aspects of dCDT performance were optimal in distinguishing individuals with PD from matched controls.

Abstract
Introduction To examine efficacy and tolerability of Levetiracetam monotherapy as a first line agent in a national cohort of children with epilepsy, naïve to anti-epileptic medication. Methods A retrospective analysis of children with epilepsy who attended 4 Irish tertiary Paediatric Neurology Clinics (2009-2015) started on Levetiracetam as a first line monotherapy. Results 182 children were identified aged one month to 16 years (mean 6.2 years (SD=5.1) Retention at 6 and 12 months was 88% (n=161) and 83% (n=145) respectively. 75% (n=104) achieved seizure freedom or > 50% improvement in seizure control at 12 months. 30% (n=55) experienced ≥1 adverse effect with aggression (12%; n=21) the most frequent. Treatment was discontinued in 16% (n=29) because of intolerance. Underlying conditions and epilepsy type were not found to influence efficacy or tolerability. Conclusion Levetiracetam monotherapy was observed as effective and safe for children with epilepsy although side effects limit tolerance in a sizeable minority.

Abstract
INTRODUCTION The most suitable treatment in most early-stage lung cancer patients is surgical resection. Despite previously assessing each patient's status being relevant to detect possible complications inherent to surgery, no consensus has been reached on which factors are "high risk" in such patients. Our study aimed to analyse the morbidity and the mortality incidence associated with this surgery in our setting with a multicentre study and to detect risk parameters. METHODS A prospective analysis study with 3,307 patients operated for bronchopulmonary carcinoma in 24 hospitals. Study variables were age, TNM, gender, stage, smoking habit, surgery approach, surgical resection, ECOG, neoadjuvant therapy, comorbidity, spirometric values, and intraoperative and postoperative morbidity and mortality. A multivariate logistic regression analysis of the morbidity and mortality predictor factors was done. RESULTS We recorded 34.2% postoperative morbidity and 2.1% postoperative mortality. Gender, myocardial infarction, angina, ECOG ≥1, COPD, DLCO <60%, clinical pathological status, surgical resection and surgery approach were shown as morbidity and mortality predictor factors in lung cancer surgery in our series. CONCLUSIONS The main variables to consider when assessing the lung cancer patients to undergo surgery are gender, myocardial infarction, angina, ECOG, COPD, DLCO, clinical pathological status, surgical resection and surgery approach.

Abstract
While the objective recording of clinical competencies in an electronic portfolio (ePortfolio) has become a key aspect of basic specialist training (BST), it continues to divide opinion. We surveyed medical trainees and their supervisors in the Dublin region examining their views of the ePortfolio and workplace-based assessments (WPBAs). Responses were received from 27 of 149 (18.1%) SHOs and 24 of 307 (7.9%) consultants. Our results highlight significant dissatisfaction amongst trainees with 20 (74.1%) stating that the ePortfolio is not an effective educational tool. Consultants had more mixed views. While 16 (66.7%) reported that feedback sessions were useful for trainee development, only 4 (16.7%) found the ePortfolio to be useful in highlighting trainees' strengths and weaknesses. Although other studies have emphasised its educational potential, our results suggest that practical barriers, such as time constraints and a lack of training, lead to poor engagement and a negative view of the ePortfolio.

Abstract
OBJECTIVE To assess how to best manage co-administration of rifabutin (RFB) and human immunodeficiency virus 1 (HIV-1) protease inhibitor (PI) containing antiretroviral treatment (ART). Recommended for initial anti-tuberculosis treatment, rifampicin (RMP) lowers PI concentrations below therapeutic levels, posing significant challenges for ART. As RFB has little effect on PI concentrations, it could be an alternative to RMP. METHODS A review of the scientific literature on the safety and efficacy of RFB for adult tuberculosis (TB) treatment was conducted, focusing on ART-TB co-therapy. A cost comparison was performed between treatment regimens, and estimates of the burden of TB disease in patients on ART were used to model RFB demand in low- and middle-income countries (LMICs). RESULTS Eleven clinical studies were identified, comprising 1543 TB patients treated with RFB; 980 (64%) were living with HIV. RFB was as safe and effective as RMP, including in 313 patients receiving co-administered ART (unboosted PIs included indinavir, nelfinavir or saquinavir; a minority received ritonavir [RTV] boosted amprenavir or saquinavir). The total cost for 6 months of all HIV and TB treatment containing RTV-boosted lopinavir (LPV) and RFB is US$410, compared to US$455 if RMP is used with LPV super-boosted with RTV. Our model suggests that demand for RFB in LMICs could be between 10,000 and 18,000 courses by 2012. CONCLUSION RFB is effective and safe in combination with the PIs studied, cost-saving for co-therapy with currently recommended boosted PIs, and may have a pivotal role in the roll-out of ART. Further research into a daily dose of RFB to simplify dosing regimens and developing fixed-dose combinations can enhance the public sector roll-out of ART.

Abstract
Aims-To investigate the expression of CD44 proteins in exfoliated urothelial cells and in tumour tissues from bladder cancer patients. A further objective was to evaluate the diagnostic potential of the changes observed in the expression of these proteins as a marker for non-invasive detection of bladder cancer.Methods-Naturally voided urine specimens were collected from 47 patients with bladder cancer or severe urothelial dysplasia (n=3) and from a control group of 43 people with no evidence of neoplastic disease. Exfoliated urothelial cells floating in the urine were pelleted by centrifugation and lysed, and their constituent proteins extracted. The pattern of expression of CD44 proteins in each sample was examined by western blot analysis using a monoclonal antibody, Hermes 3, which recognises an epitope on the polypeptide backbone of the CD44 protein. Immunohistochemical studies were performed on neoplastic (n=10) and normal (n=4) bladder tissue specimens which were snap frozen in liquid nitrogen before examination with antibodies to CD44 gene products (CD44s and CD44v6).Results-Western blot analysis revealed several high molecular weight CD44 isoforms > 160 kDa in urine cell lysates from 75% of patients with histologically confirmed bladder cancer and in two of the three patients with severe dysplasia. Such patterns were not detected in the urine cell pellets from any persons in the control group. Immunohistochemical studies of the tissue distribution of CD44s and CD44v6 showed that the differentiation and maturation of the epithelial cells in the normal bladder mucosa is accompanied by a decrease in CD44 protein expression. However, carcinoma cells overexpress standard and variant CD44 isoforms and continue to do so as they proceed through the thickened epithelial layer to the luminal surface and after they are shed into the urine.Conclusions-The abnormal expression of CD44 proteins in exfoliated cancer cells may be a useful marker for the noninvasive diagnosis of bladder cancer.

Abstract
This paper is concerned with the arguments and evidence that support the use of alcohol taxation as a primary health care intervention. Taxation is treated as a policy option that may be subject to cost-benefit analysis. While overseas evidence is used, the article draws primarily upon the authors' earlier estimates of the cost of alcohol consumption and the effects of taxation in Australia. In addition, the paper considers the main arguments used against alcohol taxation for health policy. It is concluded that the arguments cannot be substantiated and that there is a strong case for increased alcohol taxes.

Abstract
In Australia 61% of elective surgery takes place in private hospitals where current opportunities for surgical education and training (SET) are limited. The situation will shortly be compounded because of the large increase in local medical graduates, many of whom will aspire to be surgeons. How and where to train these extra surgeons to meet the expanding needs of the community must be addressed. Two models of private sector training are reviewed both of which involved combined training in both private and public sectors. Two second-year (SET 2) positions were created from one public hospital SET position by using the private sector for 3.5 days per week for 3 months of a 6-month rotation. The second model was applicable to post-fellowship training with a fairly even split between public and private sector responsibilities. In the first year, four registrars shared the two 6-month rotations for the SET 2 position. Trainees did the required minimum procedures (range 109-139) with primary operating targets of 20-25% (range 21-32%). The post-fellowship position in colorectal surgery was greatly enhanced by the private sector involvement with regard to operating experience as well as meeting part of the remuneration of the trainee. Successful models for training within the private sector in Australia can be found. To expand training in the private sector there will need to be a cultural shift in the perceptions of surgeons, patients, administrators, and trainees. Funding for posts may be available to those private hospitals that can meet the Royal Australasian College of Surgeons' accreditation standards for posts and hospitals.

Abstract
A two day meeting hosted by the World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) was held in May 2006 in Entebbe, Uganda to review the laboratory performance of virologic molecular methods, particularly the Roche Amplicor DNA PCR version 1.5 assay, in the diagnosis of HIV-1 infection in infants. The meeting was attended by approximately 60 participants from 17 countries. Data on the performance and limitations of the HIV-1 DNA PCR assay from 9 African countries with high-burdens of HIV/AIDS were shared with respect to different settings and HIV- subtypes. A consensus statement on the use of the assay for early infant diagnosis was developed and areas of needed operational research were identified. In addition, consensus was reached on the usefulness of dried blood spot (DBS) specimens in childhood as a means for ensuring greater accessibility to serologic and virologic HIV testing for the paediatric population.

Abstract
OBJECTIVE To investigate the natural history and outcome of antenatally diagnosed congenital cystic adenomatoid malformation (CCAM) of the lung. METHODS This was a retrospective study of all cases of fetal CCAM of the lung diagnosed antenatally. All cases were referred to a tertiary center for further management. A computer search identified all referred cases, and the records of these patients were examined to determine the pregnancy outcome. RESULTS In a 4-year period, 34 cases of fetal CCAM were referred for further management. At presentation, all the cases were noted to be unilateral CCAMs and the majority (79%) were microcystic in nature. The CCAMs were complicated by varying degrees of mediastinal shift (79%) and hydrops fetalis (18%). During the course of the pregnancy, the lung lesion was seen to reduce in size or resolve spontaneously in 76% of cases without any prenatal intervention (including resolution of hydrops in three cases). The overall survival rate into infancy was 88%. One pregnancy was terminated for persisting hydrops fetalis and another resulted in infant death from complications of neonatal cardiac surgery for an associated aortic coarctation. CONCLUSION The outcome of antenatally detected CCAM is much better than previously reported even when complicated by hydrops fetalis at presentation. The latter seems to be related to the high spontaneous regression rate of this tumor. Despite the antenatal resolution of CCAMs on ultrasound, postnatal follow-up is recommended in view of the long-term complications of this malformation.

Abstract
Infantile myofibromatosis is an uncommon and benign condition presenting in the neonatal period. It is self-limiting disease that may present as a localised or generalised process. Various examples of this entity have been reported in the literature. This report describes a neonate with a rapidly growing oropharyngeal lesion obstructing the airway that had the typical histological features of an infantile myofibroma. This case report highlights that a solitary myofibroma may be incredibly extensive making complete excision impossible and can be particularly challenging to manage in terms of airway stabilisation.

Abstract
Post-transplantation lymphoproliferative disorders (PTLD) are a clinicopathologically heterogeneous group of lymphoid proliferations. The majority are of B-cell origin and associated with Epstein-Barr virus (EBV) infection. In contrast, the development of T-cell PTLD is much less common and EBV does not appear to be involved in pathogenesis. In this report we describe three patients who developed large granular lymphocyte (LGL) leukaemia after renal transplantation. These patients had clonal expansion of CD3+, CD8+, CD57+, CD56- LGL. We were unable to detect CMV antigen or find evidence for EBV or human T-cell leukaemia/lymphoma virus genome in the LGL from these patients. These data show that LGL leukaemia should be included as one of the types of T-cell proliferations which can occur post transplant.

Abstract
AIM To determine the prevalence of diabetic retinopathy in patients with Down's syndrome and diabetes mellitus. METHODS Nine patients with Down's syndrome and diabetes mellitus were assessed. Factors recorded included type and duration of diabetes, level of diabetic control, blood pressure, urinalysis, and results of ophthalmological examination. RESULTS The duration of diabetes ranged from 8 to 41 years (mean 17.6 years). All had satisfactory glycaemic control and blood pressure measurements on the low side of normal (mean 106.6/70 mm Hg). One patient had early background diabetic retinopathy. The remainder had no evidence of diabetic retinopathy. CONCLUSION The low prevalence of diabetic retinopathy in these Down's syndrome patients, despite the long duration, is an interesting finding. It suggests some inherent protective factor against the development of diabetic retinopathy in this patient subgroup.

Abstract
OBJECTIVE To investigate growth and markers of collagen and bone metabolism in prepubertal children with asthma. STUDY DESIGN We measured growth velocity over 12 months and markers of collagen types I and III synthesis (PINP, PICP, PIIINP), collagen type I degradation (ICTP), and bone metabolism (bone-specific alkaline phosphatase and osteocalcin) on one occasion in 56 prepubertal children with stable asthma, 39 of whom were treated with inhaled budesonide or beclomethasone. Collagen data were compared with normal control values. RESULTS Children treated with inhaled steroids had reduced collagen synthesis (PINP, PIIINP) compared with control subjects (p = 0.038, p = 0.045), although PICP was increased (p = 0.05). Carboxyterminal telopeptide of type I collagen was reduced in patients treated with inhaled steroids (p < 0.0005) compared with nonsteroid-treated patients. Serum osteocalcin but not bone-specific alkaline phosphatase was significantly reduced in children treated with inhaled steroids (p < 0.02). Significant correlation was observed between PIIINP and ICTP and growth velocity. CONCLUSION Collagen turnover is reduced in children with asthma receiving long-term inhaled steroid treatment. Markers of collagen synthesis provide a more accurate reflection of growth disturbance than osteocalcin and bone-specific alkaline phosphatase.

Abstract
There is little or no available information on the effect of HIV discordancy in heterosexual relationships on different family members. A review of case notes was carried out on all families who had a child referred to the paediatric HIV service/family clinic at St Mary's Hospital between January 1991 and March 1996. The children had been exposed to HIV infection because they were born to HIV-positive women. There was HIV discordancy in more than one-fifth of the parents' relationships. In over 46% of the relationships, the HIV status of the natural or birth father was not known because he was either untested or unavailable. It is likely that not all of these men are infected and the number of discordant couples is greater. There were more discordant couples where the man and woman came from different ethnic groups. Consideration of the potential impact of discordancy on individual men, women and children is discussed.

Abstract
OBJECTIVE New colposcopic protocols allow examiners to better document genital trauma in rape victims. We report our findings on the locations and types of genital injury seen in female assault victims versus women engaging in consensual sex. STUDY DESIGN Physical examinations were performed on 311 rape victims seen by San Luis Obispo County's Suspected Abuse Response Team between 1985 and 1993 and contemporaneously on 75 women after consensual sexual intercourse. RESULTS Among 213 (68%) victims with genital trauma, 162 (76%) had 3.1 mean sites of injury. Comparatively, 8 (11%) consenting women had just single-site trauma. Two hundred (94%) victims had trauma at one or more of four locations, as follows: posterior fourchette, labia minora, hymen, fossa navicularis. Trauma types varied by site; tears appeared most often on the posterior fourchette and fossa, abrasions appeared on the labia, and ecchymosis was seen on the hymen. CONCLUSION A localized pattern of genital trauma can frequently be seen in women reporting nonconsensual sexual intercourse; such findings are useful for the clinical forensic examiner.

Abstract
HIV-specific cytotoxic T lymphocytes (CTLs) play an important role in the immune response to HIV infection. Long-term nonprogressors (LTNPs) or slow progressors (SPs) in HIV infection may make qualitatively different CTL responses compared to those generated by seropositive individuals who progress to disease at a faster rate. The class I molecule HLA-B*57 has been identified as one restriction element overrepresented in SP groups studied, and, together with the closely related molecule HLA-B*58, occurs commonly in ethnic groups where HIV is most prevalent. In this study, we have identified five new HLA-B*57-restricted CTL epitopes recognized by SP donors, one of which is also HLA-B*5801 restricted. These HLA-B*57-restricted responses represent the dominant HIV-specific CTL response in each of the SP donors tested. These and other such epitopes may be an important component in future vaccine design.

Abstract
Although mortality from coronary heart disease (CHD) in Australia has fallen dramatically since the 1960s, it still remains the major cause of death in Australia and poses a significant burden on the economy. Even though a number of studies have concluded that prevention has been the main determinant of the declines in CHD, a disproportionate amount of health-care expenditure is devoted to treatment rather than prevention. This paper reviews the international literature on the economic appraisal (costs and benefits) of alternative interventions for the treatment and prevention of CHD with the view of assessing whether there is sufficient evidence to justify a reallocation of resources away from treatment to prevention. First, few studies on the economic evaluation of CHD prevention and treatment programs have been undertaken in Australia, with most being from the United States and Europe. Second, assumptions about the specification, measurement and valuation of costs, and the epidemiological evidence on program effectiveness have varied. Third, health promotion and prevention programs are not necessarily more cost-effective than drug or surgical treatments for CHD. Individual interventions must be judged on their own merits. There is a need for a systematic evaluation of interventions for CHD using primary Australian data to better inform decision making on resource-allocation priorities. Such an evaluation should incorporate economic evaluation techniques.

Abstract
To determine the influence of asthma and its treatment with inhaled corticosteroids on growth, linear growth velocity, and the growth hormone axis in prepubertal children, we performed a longitudinal study for 12 months in 56 children with asthma, aged between 4.4 and 11.7 years. Height, weight, skin-fold thickness, and lung function were measured every 3 months and bone age at entry to and exit from the study. A 24-hour serum growth hormone concentration profile and fasting insulin-like growth factor I levels were measured halfway through the year. Seventy-four percent of boys and 62% of girls had heights below the 50th percentile. Growth velocity in the nonsteroid-treated control group (n = 13) was normal; 10 of 20 children taking beclomethasone grew slowly (14/20 used a dry powder device), and 4 of 19 children taking budesonide grew slowly (15/19 used a spacer). Three of four children using inhaled steroids and prednisolone grew slowly. In none of the treatment groups were measures of growth hormone secretion or levels of radioimmunoassayable serum insulin-like growth factor I affected. We conclude that slow growth in steroid-treated children with asthma does not appear to be associated with major perturbations in the growth hormone axis.

Abstract
This paper considers alternative approaches to the evaluation of the total cost of alcohol consumption in Australia. It calculates the impact of alternative tax rates on beer, wine and spirits separately and the 'consumption cost' of these taxes in terms of the distortion caused to consumption patterns. Two separate analyses are carried out. First optimal taxation is calculated which minimises the total loss from the 'consumption cost' of taxation plus the external cost of alcohol consumption. Secondly, the benefits of life are separated from other benefits and the impact of tax expressed in terms of the cost per life year gained. Conceptualised in this way, the results of this 'tax' program may be expressed in the same way as other health programs, namely as a net cost per life year gained. Alcohol taxation may then be compared with other life saving interventions. The chief conclusion reached is that in Australia there is a very compelling case for a new tax base and for a very significant increase in the rate of alcohol taxation.

Abstract
Altered proteoglycan metabolism may play a role in the development of diabetic glomerulopathy. This study was conducted to examine the effects of glucose on the production and physical characteristics of proteoglycans generated by rat mesangial cells in culture. Rat mesangial cells were exposed to elevated glucose media (500 mg/dl) or standard glucose media (200 mg/dl) for 8-10 days, and proteoglycan synthesis was determined using 35S-labeling in conjunction with anion exchange and sizing chromatography. Rat mesangial cells generated predominantly chondroitin/dermatan sulfate proteoglycans, with small amounts of heparan sulfate proteoglycans. High glucose did not alter the number of rat mesangial cells after 24 h or after 8-10 days, compared with cells grown under standard glucose conditions. The total amount of glycosaminoglycan generated and the sizes of the major proteoglycans were not different between cultures grown in standard and elevated glucose medium. Levels of mRNA for the proteoglycan, biglycan (as assessed by Northern blot analysis), also were comparable between the standard and elevated glucose conditions. Exposure to media high in glucose did not change the rate of secretion of proteoglycans from the cell layer to the medium, but did result in a greater quantity of radiolabeled proteoglycan deposited in the extracellular matrix. The cell, extracellular matrix and medium proteoglycans isolated from the elevated glucose cultures, consistently eluted from the anion exchange column at a lower [NaCl] compared with those generated under standard glucose conditions, indicating a loss of anionic charges.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE To describe patterns of attendance for follow-up among HIV infected women in Parkside, UK and their correlates. DESIGN Retrospective cohort study. SUBJECTS 103 HIV infected women. MAIN OUTCOME MEASURES Whether patients attended for follow-up between three and 18 months. RESULTS 31% of women were married and 46% had children. Women born in sub-Saharan Africa were significantly less likely to attend for follow-up after three months (56%) than women born in other areas who had acquired HIV either heterosexually (82%) or through injecting drug use (81%). This pattern persisted on multivariate analysis controlling for whether women were symptomatic, had had a previous positive test, were married or had children. CONCLUSIONS HIV positive sub-Saharan African women are less likely to reattend for follow-up than women with heterosexually acquired HIV from other areas or those who acquired infection through intravenous drug use. Further studies are needed to identify barriers to follow-up for women and to shape the development of more appropriate and accessible services for HIV infected women, especially those of sub-Saharan African origin.

Abstract
Expansion of the mesangial matrix in diabetes occurs after prolonged exposure to the diabetic milieu. To mimic the long-term hyperglycemia of diabetes mellitus we developed tissue culture systems that might approximate the chronic state. This was accomplished in two ways: (1) by growing mesangial cells on extracellular matrix glycated and crosslinked in vitro and (2) by continuously growing cells on their own matrix on filters in elevated glucose medium (500 mg/dl) for up to eight weeks without passage. Synthesis of collagen and proteoglycans was evaluated in cells grown under these conditions. In both these situations, 3H-proline incorporation into collagenase sensitive protein and 35S incorporation into sulfated proteins were reduced compared to control cultures. Despite reduction in 35S incorporation into proteoglycans in the high glucose cultures, total glycosaminoglycan content was unchanged. However, proteoglycans generated by mesangial cells grown in elevated glucose media were of a lower negative charge than controls. In mesangial cells continuously grown on filters, the levels of messenger RNA for collagen types I and IV, biglycan and TGF-beta were not different in cells grown at elevated or standard glucose concentrations for two and four weeks. We conclude that crosslinking of mesangial matrix or continuous culture of cells for prolonged periods of time in high glucose medium, which may also crosslink matrix, suppresses collagen synthesis and reduces the negative charges on matrix proteoglycans without altering mRNA levels.
