Article Synopsis
- Social isolation and loneliness (SIL) significantly affect individuals who are homeless, but their impact on health and wellbeing is not well-researched, leading to a lack of targeted policies and interventions.
- A comprehensive review examined literature from various databases, identifying 27 qualitative, 23 quantitative, and 2 mixed-method studies that address SIL in the context of homelessness, with prevalence rates varying from 25% to 90%.
- The review highlights the challenges in comparing findings due to diverse measurement tools used in studies, as well as gaps in understanding the relationship between SIL and health, wellness, and substance use among homeless populations.
Several somatic and sexual anomalies such as gynandromorphism and other morphological malformations have been described in ants, but cases of supernumerary legs in natural populations are rare, with only six cases reported to date. Moreover, few cases of abnormalities have been reported for the Ponerinae subfamily, with only three cases of genetic chimeras and five teratological cases worldwide. We report here a new case of teratology in this subfamily, with a seven-legged worker pupa found in a Neoponera villosa colony nesting in an epiphytic tank bromeliad.

Adult beetles were found in brood chambers or inner refuse piles, but also outside the ant nests, in decaying organic matter between the bromeliad leaves. No direct interactions between ants and microhisterid beetles could be observed.

This study assessed the level of CPC and changes in CPC over 6 years among adults with experience of homelessness and mental illness who received a Housing First intervention.
Methods: Participants were adults (≥18 years old) with a serious mental disorder and experiencing chronic homelessness enrolled between October 2009 and June 2011 in the Toronto site of the Canadian At Home/Chez Soi study and followed until March 2017.
