Sex With Men

Background Increasing the frequency of HIV testing is crucial for effective HIV prevention and care. The aim of the present study was to determine whether there has been a change in HIV testing among men who have sex with men (MSM) at the South Australia Specialist Sexual Health (SASSH) clinic over the past two decades. Methods: Computerised medical records of MSM who attended the SASSH at their first visit between 1994 and 2015 were used to determine whether HIV testing had changed among MSM. First HIV tests in each calendar year and return tests within 12 months were analysed. Factors associated with recent HIV testing were also examined. Results: There were 24 036 HIV tests conducted among 8163 individual MSM over the study period. The proportion of newly registered MSM who reported ever being tested for HIV declined (Ptrend = 0.030), the proportion who reported recent HIV testing did not change (Ptrend = 0.955) and the proportion who have had current HIV testing increased (Ptrend = 0.008). The proportion of MSM who returned to the clinic for HIV testing within 12 months did not change (Ptrend >0.05), with less than 40% of MSM returning for HIV testing. Factors independently associated with recent HIV testing included MSM aged ≥20 years, (odds ratio (OR) 1.79; 95% confidence interval (CI) 1.53–2.10), higher education (OR 1.28; 95% CI 1.12–1.45), non-Caucasian (African OR 1.68; 95% CI 1.30–2.17), having multiple sex partners (OR 1.47; 95% CI 1.29–1.69), having had sex interstate (OR 1.61; 95% CI 1.42–1.82) or overseas (OR 1.53; 95% CI 1.33–1.76) and injecting drug use (OR 1.56; 95% CI 1.29–1.88). Conclusions: HIV testing rate among MSM attending SASSH was suboptimal. New approaches are needed to increase the uptake and early detection of HIV infection among the high-priority MSM population.

Address Data

We conducted a cross-sectional survey of 760 Australian layer chicken farms to identify risk factors associated with the closure of poultry farms. Address data and operating status were obtained for 734 farms and more detailed responses on farm size, structure and management practices from 317 farms (41.7%). The overall prevalence of closed farms was 36.4%. Increased risk of closure was associated with independent ownership [odds ratio (OR) = 2.22, P < 0.01], location within 50 km of the centre of a state capital city (OR = 1.66, P < 0.01), being a layer farm that reared its own pullets (OR = 2.18, P < 0.01) and location within Queensland or South Australia (OR = 3.10, 3.56; both P < 0.01). Analysis of the subset of farms for which more detailed information was available identified location in South Australia (OR = 9.23, P < 0.01), use of cages (OR = 4.36, P < 0.01) and sheds with only natural ventilation (OR = 11.00, P < 0.02) as risk factors associated with a greater risk of farm closure. Our survey found that closed farms were typically independently owned, cage-layer farms located in peri-urban regions near major cities and utilising sheds without assisted ventilation.

Legionnaires Disease

Legionnaires’ disease is a potentially fatal pneumonia like infection caused by inhalation or aspiration of water particles contaminated with pathogenic Legionella spp. Household showers have been identified as a potential source of sporadic, community-acquired Legionnaires’ disease. This study used qPCR to enumerate Legionella spp. and Legionella pneumophila in water samples collected from domestic showers across metropolitan Adelaide, South Australia. A survey was used to identify risk factors associated with contamination and to examine awareness of Legionella control in the home. The hot water temperature was also measured. A total of 74.6% (50/68) and 64.2% (43/68) showers were positive for Legionella spp. and L. pneumophila, respectively. Statistically significant associations were found between Legionella spp. concentration and maximum hot water temperature (p = 0.000), frequency of shower use (p = 0.000) and age of house (p = 0.037). Lower Legionella spp. concentrations were associated with higher hot water temperatures, showers used at least every week and houses less than 5 years old. However, examination of risk factors associated with L. pneumophila found that there were no statistically significant associations (p > 0.05) with L. pneumophila concentrations and temperature, type of hot water system, age of system, age of house or frequency of use. This study demonstrated that domestic showers were frequently colonized by Legionella spp. and L. pneumophila and should be considered a potential source of sporadic Legionnaires’ disease. Increasing hot water temperature and running showers every week to enable water sitting in pipes to be replenished by the municipal water supply were identified as strategies to reduce the risk of Legionella in showers. The lack of public awareness in this study identified the need for public health campaigns to inform vulnerable populations of the steps they can take to reduce the risk of Legionella contamination and exposure.

Toxoplasma Gondii Infection

Toxoplasmosis in sheep is a disease of great importance in veterinary medicine, which causes economic losses in livestock and has a great impact on human health, since consumption of infected meat facilitates transmission of zoonotic infections. Blood samples from sheep (n = 360) were collected from 13 farm properties in the municipality of Lages, Santa Catarina, to estimate the prevalence of toxoplasmosis and identify risk factors associated with Toxoplasma gondii infection. T. gondii, antibodies were investigated by means of the indirect immunofluorescence assay (IFA) and enzyme-linked immunosorbent assay (ELISA). Animals infected with T. gondii were found on 100% of the farms. IFA detected 56.9% (205/360) and ELISA 42.5% of the infected sheep. Breed was the only risk factor associated with the presence of T. gondii antibodies. ELISA showed sensitivity of 61%, specificity of 82% and kappa of 0.41, which was considered moderate. This allows use of ELISA as an alternative technique for diagnosing T. gondii in sheep.

SUMMARYTo assess the impact of Bordetella pertussis infections in South Australia during an epidemic and determine vulnerable populations, data from notification reports for pertussis cases occurring between July 2008 and December 2009 were reviewed to determine the distribution of disease according to specific risk factors and examine associations with hospitalizations. Although the majority (66%) of the 6230 notifications for pertussis occurred in adults aged >24 years, the highest notification and hospitalization rate occurred in infants aged <1 year. For these infants, factors associated with hospitalization included being aged <2 months [relative risk (RR) 2·3, 95% confidence interval (CI) 1·60–3·32], Indigenous ethnicity (RR 1·7, 95% CI 1·03–2·83) and receiving fewer than two doses of pertussis vaccine (RR 4·1, 95% CI 1·37–12·11). A combination of strategies aimed at improving direct protection for newborns, vaccination for the elderly, and reducing transmission from close contacts of infants are required for prevention of severe pertussis disease.

Abstract An epidemiological study was conducted to identify risk factors related to small ruminant lentivirus (SRLV) infection in the central region of Spain. Between October 1998 and October 2000, a total of 194 sheep from 10 flocks and 163 goats from three flocks were tested for SRLV antibodies, resulting in 65.5% and 8.0% of seroprevalence, respectively. The relationship between differences in prevalence of SRLV, geographical location of the flock, and possible factors related to the flock that could enhance transmission were studied. Results of multivariable analysis showed an association between SRLV infection and geographical location of the flock and the rearing system. In addition, the differences in the productivity between infected and non-infected animals were explored. The productivity parameters were measured in 62 sheep and 28 goats. All productivity parameters studied (milk production, number of milking days, and lambing rate) appeared to be reduced in the SRLV-seropositive group in both goats and sheep. Even though, these differences were not statistically significant, it seems that animals infected are less productive than these non-infected. Statistical analyses comparing infected and non-infected sheep showed no statistical relationship between SRLV infection and milk quality.

Background: Despite the known benefits of cardiac rehabilitation (CR) and widespread endorsement of its use, CR is vastly underutilised, with less than 30% of eligible patients participating in a CR program after a cardiac event. The current study assessed the factors independently associated with referral to CR following acute myocardial infarction (AMI). Methods: The CR referral rate and factors associated with referral were assessed among all consecutive patients undergoing coronary angiography for AMI and surviving to hospital discharge, attending South Australian public hospitals from January 2012 [[Unable to Display Character: &#8211;]] December 2013. Data was maintained by the Coronary Angiogram Database of South Australia (CADOSA), a comprehensive registry compatible with the NCDR ® CathPCI ® Registry. Results: Among 3,212 patients undergoing angiography for AMI, CR referral occurred in 1,530 patients (48%). Compared to patients without CR referral, these patients were younger (62±13 vs. 64±14, p<0.01) and less likely to be female (25% vs. 34%, p<0.01). Following age-adjusted analysis, the cardiovascular risk factors were similar between CR referral and non-CR referral patients including: diabetes (29% vs. 30%, p>0.5), hypertension (61% vs. 64%, p>0.5), and dyslipidaemia (59% vs. 60%, p>0.5), but CR referral patients were more likely to be active smokers (40% vs. 33%, p<0.01). CR referral patients were less likely to have additional comorbidities including current dialysis (0.9% vs. 2.2%, p<0.01) and cerebrovascular disease (6.0% vs. 8.8%, p<0.01). In multivariable analyses, factors associated with increased CR referral were (c statistic 0.68): presentation with ST-elevation MI (STEMI) (1.4, 1.2-1.7, p<0.01), undergoing percutaneous coronary intervention (PCI) following angiography (1.6, 1.4-1.9, p<0.01) and younger age (1.0, 0.98-1.0, p<0.01). Prior CABG (0.6, 0.5-0.8, p<0.01) and absence of significant coronary artery disease, defined by stenosis <50%, (0.2, 0.1-0.3, p<0.01) were associated with decreased referral. Lastly, secondary prevention therapies were more often prescribed at discharge in patients with CR referral compared to patients without referral including: aspirin (93% vs. 82%, p<0.01), beta-blockers (64% vs. 61%, p<0.05), statin (92% vs. 78%, p<0.01), and ACE-inhibitor/angiotensin receptor blocker (84% vs. 74%, p<0.01). Conclusion: This study highlights a significant disparity in cardiovascular care with approximately half of AMI patients not referred to CR, despite it being a key performance measure. STEMI presentation, younger age and undergoing PCI are associated with increased referral. Alarmingly, AMI patients not referred to CR are also less likely to receive other guideline-based therapies. Increased physician awareness about the benefits of CR is required and initiatives to overcome barriers to referral may improve the delivery of evidence-based care.

AbstractIntroduction:The majority of research that has explored workplace violence has focused on establishing the prevalence of violence in different settings. In general, there is a paucity of research that explores factors that may predict or increase the risk of experiencing violence in the workplace.Objective:The aim of this research was to determine predictors of violence for paramedics.Methods:A questionnaire was developed that focused on paramedics' experi-ences with six forms of violence: verbal abuse, property damage/theft, intimi-dation, physical abuse, sexual harassment, and sexual assault.The questionnaire was distributed randomly to paramedics throughout rural Victoria and metropolitan South Australia, and completed and returned anonymously.Results:Predictors emerged for verbal abuse, intimidation, sexual harassment, and sexual abuse. Specifically, gender was the only predictor of intimidation, sexual harassment, and sexual assault. Paramedic qualifications, how they responded to a call-out, and hours per week in direct patient contact emerged as a predictor of verbal abuse.Conclusions:Certain factors predict or predispose paramedics to workplace violence. The need for workplace violence education and training is impera-tive for the prevention of violence, as well as for its management.
