This article addresses the continuing resilience of two post-Soviet governments – Azerbaijan and Lithuania – against community-based engagement and social protection of HIV-positive people by exploring the challenges of two social activists. The analysis shows how basic social and medical needs of people living with HIV/AIDS remain unmet, while stigmatisation informs the local health policies and manifests as a protective mechanism against contrary promotion effects. The findings call for urgent policy changes to prevent the further suffering of these people because of poor state strategies. The aim is to help further intervention practices and improve social care services for HIV-positive people in the two countries.
Cannabis is the most commonly used illicit drug in the world. However, because of a changing legal landscape and rising interest in therapeutic utility, there is an increasing trend in (long-term) use and possibly cannabis impairment. Importantly, a growing body of evidence suggests that regular cannabis users develop tolerance to the impairing, as well as the rewarding, effects of the drug. However, the neuroadaptations that may underlie cannabis tolerance remain unclear. Therefore, this double-blind, randomized, placebo-controlled, cross-over study assessed the acute influence of cannabis on the brain and behavioral outcomes in two distinct cannabis user groups. Twelve occasional and 12 chronic cannabis users received acute doses of cannabis (300-μg/kg delta-9-tetrahydrocannabinol) and placebo and underwent ultrahigh field functional magnetic resonance imaging and magnetic resonance spectroscopy. In occasional users, cannabis induced significant neurometabolic alterations in reward circuitry, namely, decrements in functional connectivity and increments in striatal glutamate concentrations, which were associated with increases in subjective high and decreases in performance on a sustained attention task. Such changes were absent in chronic users. The finding that cannabis altered circuitry and distorted behavior in occasional, but not chronic users, suggests reduced responsiveness of the reward circuitry to cannabis intoxication in chronic users. Taken together, the results suggest a pharmacodynamic mechanism for the development of tolerance to cannabis impairment, of which is important to understand in the context of the long-term therapeutic use of cannabis-based medications, as well as in the context of public health and safety of cannabis use when performing day-to-day operations.

Therefore, this double-blind, randomized, placebo controlled, cross-over study assessed the acute influence of cannabis on brain and behavioral outcomes in two distinct cannabis user groups. Twelve occasional (OUs) and 12 chronic (CUs) cannabis users received acute doses of cannabis (300 μg/kg THC) and placebo, and underwent ultra-high field functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy (MRS). In OUs, cannabis induced significant neurometabolic alterations in reward circuitry, namely decrements in functional connectivity and increments in striatal glutamate concentrations, which were associated with increases in subjective high and decreases in performance on a sustained attention task. Such changes were absent in CUs. The finding that cannabis altered circuitry and distorted behavior in OUs, but not CUs, suggests reduced responsiveness of the reward circuitry to cannabis intoxication in chronic users Taken together, the results suggest a pharmacodynamic mechanism for the development of tolerance to cannabis impairment.
Garbage piles up in the capital of Cambodia; it lies around in corners, on streets, in fields. COVID-19, which has led to a global reduction in the production of greenhouse gases considered utopian, has had little if any significant impact within this country, where garbage is produced in the same amounts, likewise burned and buried, or dumped into the rivers. The smelly sewage channels of Phnom Penh run as brown as usual, patterned with flip-flops, shampoo packaging, diverse plastic particles, and undefinable fragments of rubbish, travelling south-eastwards into the morning glory fields; passing by buzzing, still active markets, passing urban poor areas, where children play in the thick mud, passing citizens in facemasks. On 10 April, the Cambodian government counted some 120 official cases of COVID-19 infection among its populace...
Wie es Eltern und ihren Kindern während der Corona-Pandemie geht, wie ihr aktuelles Wohlbefinden ist, was ihren Alltag kennzeichnet, wie die Passung zu den Regelungen der Kitabetreuung, Schulöffnung und auch der Arbeitgeber*innen ist – dies sind die Kernfragen der Onlinebefragung KiCo, welche im Zeitraum vom 24.04.2020 – 03.05.2020 durchgeführt wurde. Dieses Papier präsentiert erste Ergebnisse der Studie, an der über 25.000 Personen teilgenommen haben. Die Studie wurde umgesetzt vom Forschungsverbund "Kindheit – Jugend – Familie in der Corona-Zeit", der sich aus den Universitäten Hildesheim, Frankfurt und Bielefeld zusammensetzt.
Dieses Papier präsentiert erste Ergebnisse der bundesweiten Studie JuCo – Erfahrungen und Perspektiven von jungen Menschen während der Corona-Maßnahmen. Die Befragung wurde vom Forschungsverbund "Kindheit – Jugend – Familie in der Corona-Zeit" umgesetzt, der sich aus den Universitäten Hildesheim, Frankfurt und Bielefeld zusammensetzt. Über 5.000 Jugendliche und junge Erwachsene zwischen 15 und 30 Jahren sind in die Analysen eingeflossen und zeigen auf, wie es den jungen Menschen geht und welche Botschaften sie haben.
