IntroductionThe Watersports Inclusion Games is a free annual weekend event, where young people with a range of physical and intellectual disabilities and their families/siblings participate in various inclusive watersports activities.ObjectivesThis study aims to assess the psychological benefits of watersports for young people with various physical and intellectual disabilities and investigate the extent of the impact of the COVID-19 pandemic on their access to watersports.MethodsFollowing a literature review, a survey containing both quantitative and qualitative aspects was constructed using SurveyMonkey and circulated to the parents/guardians of participants three times following the event. The survey was completed anonymously on an opt-in basis and 28 responses that met our criteria for analysis were collected. Qualitative data from free-text responses were grouped under themes and quantitative data was analysed using SPSS.ResultsDespite 64% (n=18) of respondents indicating that their disability increased their vulnerability to COVID-19 in some capacity, the effect of the pandemic on accessibility was not statistically significant. This could be due to the small response number, or the everyday limitations participants faced prior to the pandemic. 92% (n=25) of participants indicated that there was great inclusion in the watersports activities and that they were “very beneficial” regarding the possibility of the whole family’s participation [p=0.005]. The survey also found a statistically significant association between the event’s activities being considered both “accessible” and “very beneficial” in terms of boosting self-confidence, with 57.1% of responses indicating agreement to this. (p=0.016)ConclusionsFull-family participation and accessibility of activities were key facilitators to the enjoyment and benefit of participants. Programmes should be established that allow able-bodied siblings and young people with disabilities to participate in the same activities.Disclosure of InterestNone Declared

Point-of-care (POC) measurement of glucose is currently recommended only for the monitoring of gestational diabetes mellitus (GDM). This prospective observational study evaluated the use of POC measurements of maternal glucose to diagnose GDM in women being screened selectively with a 1-step 75 g oral glucose tolerance test (OGTT). The strictest preanalytic and analytic international laboratory standards were applied to measure maternal plasma glucose at fasting and at 1 and 2 h post glucose load. The recent International Association of Diabetes and Pregnancy Study Groups diagnostic criteria were used. At the same time, maternal capillary glucose was measured. Because of differences in plasma and capillary glucose measurements, regression analysis of POC capillary glucose results vs laboratory plasma glucose results was conducted. The regression equations for plasma glucose were derived in a derivation cohort (n = 102). These equations were applied in the validation cohort (n = 100). Predicted and actual plasma glucose values were compared. Of the 202 women screened, 36.6% were nulliparous, 56.4% were obese, and 81.2% were Irish-born. Two thirds had a single risk factor for GDM, and a third had multiple risk factors. Based on the plasma measurements, 53.5% had GDM. As a predictor of GDM, the diagnostic accuracy of POC measurement was 83.0% (95% confidence interval, 74.2-89.8). In high-resource settings where measures to inhibit glycolysis are implemented, the use of POC measurements for the diagnosis of GDM is not justified based on this study. In low- and medium-resource settings, where measures to inhibit glycolysis are not achievable, regression analysis using POC measurements may be acceptable compared with plasma samples subject to glycolysis.

An unblinded crossover study of fenitrothion 0.18 mg/kg/day [36 times the acceptable daily intake (ADI)] and 0.36 mg/kg/day (72 × ADI) administered as two daily divided doses for 4 days in 12 human volunteers was designed and undertaken after results from a pilot study. On days 1 and 4, blood and urine samples were collected for analysis of fenitrothion and its major metabolites, as well as plasma and red blood cell cholinesterase activities, and biochemistry and hematology examination. Pharmacokinetic parameters could only be determined at the higher dosage, as there were insufficient measurable fenitrothion blood levels at the lower dosage and the fenitrooxone metabolite could not be measured. There was a wide range of interindividual variability in blood levels, with peak levels achieved between 1 and 4 hr and a half-life for fenitrothion of 0.8-4.5 hr. Although based on the half-life, steady-state levels should have been achieved; the area under the curve ( AUC)0-12 hrto AUC0-∞ratio of 1:3 suggested accumulation of fenitrothion. There was no significant change in plasma or red blood cell cholinesterase activity with repeated dosing at either dosage level of fenitrothion, and there were no significant abnormalities detected on biochemical or hematologic monitoring.

A novel form of inflammatory bowel disease has been reported in a cohort of children with developmental disorder, manifesting predominantly as regressive autism (affected children). The intestinal pathology includes ileo-colonic lymphoid nodular hyperplasia (LNH) and a subtle enterocolitis. Clinical and pathological aspects of this disorder have previously been reported. In ileal lymphoid tissues of affected children, the presence of reactive follicular hyperplasia may reflect antigenic presence at this site. We have examined a possible association between measles virus (MV) and a chronic enterocolitis in these children. We sought to detect and localise MV in intestinal tissues from affected children.

Abstract Objectives: To identify the source of an international outbreak of food poisoning due to Salmonella agona phage type 15 and to measure how long the underlying cause persisted. Design: Case-control study of 16 primary household cases and 32 controls of similar age and dietary habit. Packets of the implicated foodstuff manufactured on a range of days were examined for salmonella. All isolates of the epidemic phage type were further characterised by pulsed field gel electrophoresis. Results: 27 cases were identified, of which 26 were in children. The case-control study showed a strong association between infection with S agona phage type 15 and consumption of a peanut flavoured ready to eat kosher savoury snack imported from Israel. S agona phage type 15 was isolated from samples of this snack. The combined food sampling results from the United Kingdom, Canada, the United States, and Israel showed that contaminated snacks were manufactured on at least seven separate dates during a four month period between October 1994 and February 1995. Voluntary recalls of the product successfully interrupted transmission. Conclusions: Rapid international exchanges of information led to the identification of the source of a major outbreak of S agona in Israel and of associated cases in North America. The outbreak showed the value of the Salm-Net surveillance system and its links outside Europe, both for increasing case ascertainment and for improving the information on the duration of the fault at the manufacturing plant. Key messages International surveillance networks can strength- en infection control When a foodstuff is contaminated it is important to examine as many batches as possible to show the duration of the production fault

Aim: To analyse and compare expression patterns of three potential biomarkers—p16INK4A, CDC6, and MCM5—and evaluate their use as predictive biomarkers in squamous and glandular cervical preinvasive neoplasia. Methods: Immunocytochemical analysis of p16INK4A, MCM5, and CDC6 expression was performed on 20 normal, 38 cervical intraepithelial neoplasia 1 (CIN1), 33 CIN2, 46 CIN3, 10 squamous cell carcinoma, 19 cervical glandular intraepithelial neoplasia (cGIN), and 10 adenocarcinoma samples. Staining intensity was assessed using a 0–3 scoring system. p16INK4A, MCM5, and CDC6 expression was also examined in ThinPrep slides exhibiting mild, moderate, and severe dyskaryosis. Human papillomavirus (HPV) was detected using a modified SYBR green assay. Fluorogenic polymerase chain reaction (PCR) and solution phase PCR were used for specific HPV typing. Results: All three markers showed a linear correlation between expression and grade of dysplasia. p16INK4A and MCM5 protein expression was upregulated in all grades of squamous and glandular dysplasia. CDC6 protein was preferentially expressed in high grade lesions and in invasive squamous cell carcinoma. Conclusion: p16INK4A expression was closely associated with high risk HPV infection—all grades of squamous and glandular cervical lesions were immunohistochemically positive. MCM5 staining intensity was independent of high risk HPV infection, highlighting its potential as a biomarker in both HPV dependent and independent cervical dysplasia. CDC6 may be a biomarker of high grade and invasive lesions of the cervix, with limited use in low grade dysplasia. p16INK4A was the most reliable marker of cervical dysplasia. Combinations of dysplastic biomarkers may be useful in difficult diagnostic cases.

Aim: To examine the potential of p16INK4A as a biomarker for dysplastic squamous and glandular cells of the cervix in tissue sections and ThinPrep™ smears. Methods: Immunocytochemical analysis of p16INK4A expression was performed on 22 normal cervical tissue samples, five cervical glandular intraepithelial neoplasia (cGIN), 38 cervical intraepithelial neoplasia 1 (CIN1), 33 CIN2, 46 CIN3, and 10 invasive cancer cases (eight squamous and two adenocarcinomas). All samples were formalin fixed and paraffin wax embedded, and immunohistochemical analysis was carried out using a mouse monoclonal anti-p16INK4A antibody after antigen unmasking. The staining intensity was assessed using a 0 to 3 scoring system. In addition, the expression status of p16INK4A was examined in 12 normal ThinPrep smears, one smear exhibiting cGIN, and a total of 20 smears exhibiting mild, moderate, and severe dyskaryosis. Human papillomavirus (HPV) detection was carried out using a modified SYBR green assay system. Fluorogenic polymerase chain reaction (PCR) and solution phase PCR were used for specific HPV typing. Results: p16INK4A immunoreactivity was absent in all normal cervical tissues examined. Dysplastic squamous and glandular cells were positive for p16INK4A expression in all cases included in this study, except for one CIN3 case. p16INK4A expression was mainly nuclear in CIN1 cases, and both nuclear and cytoplasmic in CIN2, CIN3, cGIN, and invasive cases. All cases positive for HPV expressed the p16INK4A protein, although not all cases found positive for p16INK4A were HPV positive. In general, the p16INK4A staining intensity was lower in cases negative for HPV or those containing a low risk HPV type. Conclusion: This pattern of overexpression demonstrates the potential use of p16INK4A as a diagnostic marker for cervical squamous and also glandular neoplastic lesions. In addition, the technique can be used to identify individual dyskaryotic cells in ThinPrep smears. Thus, p16INK4A is a useful marker of cervical dyskaryosis.

The prevalence of bronchial hyperresponsiveness in adult populations is not known. To document its prevalence and distribution and to determine the factors associated with it, a random sample of the adult population of Busselton, Western Australia, was studied. Spirometric function, bronchial responsiveness to histamine, and atopic responses to skin prick tests were measured. Respiratory symptoms were determined by questionnaire. Data were obtained from 916 subjects. Of these, 876 underwent a histamine inhalation test and bronchial hyperresponsiveness to histamine (defined as a dose of histamine provoking a 20% fall in FEV1 equal to or less than 3.9 mumol) was found in 10.5%. Another 40 subjects with poor lung function were tested with a bronchodilator and 12 were found to have bronchial hyperresponsiveness (defined as a greater than 15% increase in FEV1), making the total prevalence of bronchial hyperresponsiveness 11.4%. The prevalence of current asthma, defined as bronchial hyperresponsiveness plus symptoms consistent with asthma in the last 12 months, was 5.9%. The distribution of bronchial hyperresponsiveness in the studied population was continuous. There was a significant association between it and respiratory symptoms, atopy, smoking, and abnormal lung function (p less than 0.001 for all associations). There was no association with age, sex, or recent respiratory tract infection.
