The prevalence of older people who use drugs is increasing in many countries, with evidence that some women continue or begin illicit substance use in midlife and older age. While research on older people who use drugs is limited, evidence of risk behaviours among older women who use drugs is particularly inadequate. Unsafe drug use and sexual practices that are prolonged and sustained over many years increase the possibilities for poorer health, leading to potentially greater morbidity and early mortality among older drug users. This chapter is a timely contribution to the extant literature and explores our current knowledge of the risk behaviours of older women who use drugs.

Although midlife is viewed as a transition period in the life course, the normative role expectations of midlife and older women run parallel to the stereotypes of women who use drugs. Furthermore, drug-using bodies are politically and culturally shaped through control and containment practices centred around notions of difference and risk. Acknowledging the intersection of age, race and gender, this chapter frames its position around the concepts of ‘risk’ and ‘edgework’. Utilising these theoretical concepts, this chapter argues that a shift towards a support-focussed model, rather than control of, older women who use drugs is required. The absence of a focussed, gendered analysis of the lives and experiences of older drug users, and older women who use drugs in particular, limits our understanding. Consequently, the chapter concludes with a call for well-designed studies of this increasing and largely hidden cohort of drug users.

Eastern Europe and Central Asia (EECA) is home to 21% of the world’s population of people who inject drugs and it is the region with the fastest-growing HIV epidemic. HIV prevalence among women who inject drugs is significantly higher than among men in EECA. Even in places with high coverage of needle syringe programmes and HIV testing and treatment, women’s access to opioid substitution treatment is lower than men, and women’s sexual and reproductive health needs remain unaddressed. EECA has a unique system of drug registries that store the personal data of people who use drugs. Registration lowers the chances of employment and access to education and for women and increases the risk of losing custody of their children. The system of drug registries contributes to drug-related stigma. Breaches of confidentiality of drug registry data lead to the further marginalisation of women who use drugs. Criminalisation, past experience of police violence and poverty contribute to healthcare access barriers for women. There is a need for legislative changes to improve personal data protection, decriminalise drug use and reduce police violence. The positive effects of these changes would only be seen in the long term. In the interim, women need special access programmes that are designed specifically to address their needs, that provide free-of-charge services and that ensure the safety and confidentiality of personal data.

It is widely believed that transgender individuals in Nepal inject silicone for face and body manipulation, a phenomenon thought to be common among transgender individuals globally. Therefore, this qualitative study conducted in Nepal explored: (1) awareness of silicone use and sources of information; (2) reasons for using silicone; (3) notion of cost and quality of these procedures; (4) reported negative aspects, including side effects and (5) health seeking behaviors of Nepali transgender women.

The authors carried out eight focus group discussions (FGDs) with transgender women at four different districts of Nepal, five in the capital Kathmandu and three in different rural areas. We also interviewed three transgender women who preferred not to participate in the FGD but were happy to be interviewed separately. Similarly, six interviews with stakeholders working for sexual and gender minority populations were also conducted.

Most FGD participants were young (mean age 23.06 ± 3.9 years) and the majority (55%; n = 34) completed grade six to high school level. Peer networks of transgender people and the Internet were the more popular sources of information about silicone. The decision to use silicone was largely influenced by the desire to look beautiful and more feminine. Often they appear not to follow the recommended procedures for silicone use. Their health seeking behavior regarding side effects or complications of these procedures was very poor.

Findings reflect that targeted interventions aimed at transgender individuals should educate them on the use of silicone, as well as explore safe and affordable approaches to meet gender-related appearance needs of Nepali transgender people.

This paper aims to develop a credit-risk model in which firms face rollover risk, and the markets for defaulted assets are segmented due to entry costs. The paper shows that reducing the entry costs in this economy may decrease the total surplus of the economy. This outcome can arise because when market barriers are lifted, the gap between the liquidation prices across the markets will shrink, but then the market that would experience a price drop may face more bankruptcies because the rollover risk will increase in that market. The paper describes under which condition such an intervention policy improves or hurts the total surplus.

The purpose of this study is to analyze the nonhomogeneous model on the mixed convection of Al2O3–Fe3O4 Bingham plastic hybrid nanofluid in a ventilated enclosure subject to an externally imposed uniform magnetic field. Entropy generation and the pressure drop are determined to analyze the performance of the heat transfer. The significance of Joule heating arising due to the applied magnetic field on the heat transfer of the yield stress fluid is described.

The ventilation in the enclosure of heated walls is created by an opening on one vertical wall through which cold fluid is injected and another opening on the opposite vertical wall through which fluid can flow out.

This study finds that the inclusion of Fe₃O₄ nanoparticles with the Al₂O₃-viscoplastic nanofluid augments the heat transfer. This rate of enhancement in heat transfer is higher than the rate by which the entropy generation is increased as well as the enhancement in the pressure drop. The yield stress has an adverse effect on the heat transfer; however, it favors thermal mixing. The magnetic field, which is acting opposite to the direction of the inlet jet, manifests heat transfer of the viscoplastic hybrid nanofluid. The horizontal jet of cold fluid produces the optimal heat transfer.

The objective of this study is to analyze the impact of the inclined cold jet of viscoplastic electrically conducting hybrid nanofluid on heat transfer from the enclosure in the presence of a uniform magnetic field. The combined effect of hybrid nanoparticles and a magnetic field to enhance heat transfer of a viscoplastic fluid in a ventilated enclosure has not been addressed before.
