Addressing injecting related risks among people who inject both opioids and stimulants: Findings from an Australian survey of people who inject drugs.

BACKGROUND: Opioids and stimulants are the most commonly injected illicit drugs worldwide and in Australia. While some people who inject drugs (PWID) prefer either opioids or stimulants, others regularly use both opioids and stimulants. Limited available research indicates that those who use opioids and stimulants together, either in combination or alternating between the two, may engage in injection-related practices which potentially place them at greater health risk and could lead to poorer health outcomes. METHODS: Participants were recruited nationally through member organizations of the Australian Injecting and Illicit Drug Users League (AIVL); these organizations represent PWID in each Australian state and territory. This study compared a sample of PWID (N = 535) who reported past-month injection of opioids only (N = 173), stimulants only (N = 208), or both (N = 154) on a range of health and wellbeing outcomes. PWID completed a survey assessing drugs injected, frequency of injecting, receptive equipment sharing, psychological distress, self-reported hepatitis C (HCV) status, experienced and internalized stigma, drug use salience, and community attachment. RESULTS: People who injected both opioids and stimulants reported more frequent injecting, more experiences of stigma, and greater reported HCV diagnosis than people who injected stimulants or opioids alone. They also showed greater attachment to a community of PWID and greater salience of drug use to their identity. CONCLUSIONS: The findings of increased injecting and broader harms associated with injecting both stimulants and opioids are important for tailoring harm reduction and intervention designs for people who use both opioid and stimulant drugs, including prioritizing peer-based approaches.

Nurse provision of support to help inpatients quit smoking.

Issue addressed Identification of the factors that facilitate nurses to provide smoking cessation advice to hospitalised patients. Method Six semistructured focus groups with 26 nurses were conducted in June 2015. Participants completed a structured survey to collect patient demographic data and assess attitudes towards their role in addressing smoking cessation among inpatients. Results Important themes that emerged from the qualitative data were: nurses' negative perceptions of smokers, nurses' confidence in their knowledge of smoking cessation care and nurses' uncertainty around whose role it is to provide smoking cessation care. Conclusion Nurses require training in order to confidently and competently address smoking among inpatients as part of routine care. Formal ways to document the smoking status of inpatients and the offer of smoking cessation support from a nurse to an inpatient would enhance the communication between nurses around which inpatients had been asked about their smoking status and which had not. For patients who are resistant to conventional cessation strategies, innovative ways are needed to reduce the harm caused to them by tobacco use. So what? Nurses need to be provided with education and training around smoking cessation to increase their confidence and skills to provide smoking cessation care to inpatients.

Clinical and social determinants of diarrhoeal disease in a rural HIV/AIDS clinic, South Africa: a case-control study.

Diarrhoeal diseases are a common cause of morbidity and are associated with mortality in HIV-infected populations. Little is known about the contribution of clinical and socio-environmental factors to the risk of diarrhoea in these populations in rural sub-Saharan Africa. We conducted a case-control study of people attending a rural HIV clinic with an episode of diarrhoea in Bushbuckridge, South Africa. Cases were defined as HIV-positive adults with symptoms of diarrhoea before or after initiation of antiretroviral therapy (ART). Controls without diarrhoea were randomly selected from clinic attendees. Structured questionnaires and case-file reviews were undertaken to describe clinical and socioenvironmental risk factors. We recruited 103 cases of diarrhoea from 121 patients meeting case definitions. Cases were more likely to be women (P = 0.013), aged over 45 years (P = 0.002), divorced or separated (P = 0.006), have limited formal education (P = 0.003), have inadequate access to sanitation facilities (P = 0.045), have water access limited to less than three days per week (P = 0.032) and not yet initiated on ART (P < 0.001). In multivariate analysis, diarrhoea remained associated with female gender (adjusted odds ratio [aOR]: 2.02, 95% CI 1.10-3.73), older age (aOR: 6.31, 95% CI 1.50-26.50), limited access to water (aOR: 2.66, 95% CI 1.32-5.35) and pre-ART status (aOR: 5.87, 95% CI 3.05-11.27). Clinical and socio-environmental factors are associated with occurrence of diarrhoeal disease among rural HIV patients in South Africa. Further intervention research is urgently needed, combining community- and clinic-based approaches, to improve access to water, sanitation and ART for rural areas with high HIV prevalence, along with structural interventions to address gender inequities.

A review of water and sanitation provision in refugee camps in association with selected health and nutrition indicators--the need for integrated service provision.

The first global overview of basic water and sanitation indicators in refugee camps is presented (using data from 2003-2006) and compared with selected health and nutrition indicators. This demonstrates that average levels of water and sanitation provision are acceptable at camp level but many refugee operations are suffering from gaps that cross-cut these sectors; e.g. typically poor sanitation provision is corresponding with low per capita availability of water. These findings were confirmed at household level with two household surveys undertaken in African refugee camps; households reporting a case of diarrhoea within the previous 24 hours collect on average 26% less water than those not reporting any cases. In addition, typically higher levels of morbidity of one infectious agent are also reflected across other infectious agents; this is reinforced by comparing the relationship between morbidity and nutrition status from selected camps. The importance that hygiene, environmental conditions and local settings have on health (both of refugees and also local communities) is underlined. Interventions to improve indicators across the water, sanitation, health and nutrition sectors rely not only on increased and sustained resources but must entail an integrated approach to simultaneously tackle short-comings across all these vital sectors.

Induction of ovulation and natural oestrous cycling in the Stripe-faced Dunnart, Sminthopsis macroura.

Induced ovulation allows reproduction by otherwise infertile females, and is ideal for the captive breeding of endangered species where the population is aged or breeding is unsuccessful. A predictable time of ovulation after induction has not yet been achieved in polyovular marsupials. Ovulation was induced in Sminthopsis macroura using an initial injection of 20 IU equine serum gonadotrophin (eSG; Day 0), followed on Day 4 by either 20 IU eSG (n = 25) or 0.5 mg porcine luteinizing hormone (n = 26). I.p. hormone injection was given in the morning or early evening, and reproductive status was established prior to induction. Five non-cyclic animals began to cycle naturally following induction and one gave birth to a litter. The time of ovulation after the 1st injection (7.8 +/- 0.9 days) was significantly shorter (P = 0.000) and less variable than the previous study, mimicked the timing of natural cycling, and both natural and induced animals ovulated in the early morning. In vitro oocyte movement through the oviduct, observed for the first time in a marsupial, occurred in pulses. We estimated one group of oocytes could travel the length of the oviduct in 40 min, but it was probably around 4 h. The entire ovulation time (including multiple ovulations) was estimated at 7.5 h. This study has achieved a predictable timing of ovulation after stimulation, and induced noncyclic animals to cycle naturally and give birth, providing a modified methodology for use in captive breeding programs of endangered dasyurid marsupial species with low fecundity.

Comparison of the OptiMAL rapid antigen test with field microscopy for the detection of Plasmodium vivax and P. falciparum: considerations for the application of the rapid test in Afghanistan.

To establish the sensitivity and specificity of a batch of 'OptiMAL 48' rapid antigen tests procured by the World Health Organization in Afghanistan, a sample was tested, in parallel with routine, microscopical diagnosis, at basic health units (BHU) within Afghan refugee camps in Pakistan. The results of both methods of field diagnosis were compared with those of cross-checking microscopy at a reference laboratory, which were taken as the 'gold standard'. Out of 499 patients examined, 36% were diagnosed as malaria cases by field microscopy and 34% by the rapid test. For the OptiMAL 48 test, cross-checking of the corresponding smears at the reference laboratory gave a sensitivity of 79.3% and a specificity of 99.7% for Plasmodium falciparum and corresponding values of 86.1% and 98.7% for P. vivax infections. The performance of the field microscopy was better, with a sensitivity and specificity of 85.2% and 99.7% for P. falciparum, and 90.4% and 98.7% for P. vivax, respectively. These results show that the performance of OptiMAL 48 is adequate for acute- and post-emergency situations when the alternative is just clinical diagnosis. However, in the developing health system of Afghanistan, the main focus should be on the expansion of the existing network for microscopical diagnosis and quality control, to meet the needs of a stable situation. Rapid antigen tests are more suited to investigations of outbreaks in remote situations, where health services are deficient or absent.
