## Short Segments Today, we explore how deep-rooted medical bias can have deadly consequences for addiction patients, the promising results of THC medication for PTSD nightmares, and Cambodia's achievement in HIV targets. We'll also discuss a new study on an osteoporosis drug that blocks spinal damage, and insights from ADHD youth on transitioning to adulthood. Later, we'll dive into how nearly half of dementia cases may be linked to modifiable risks. Medical bias in addiction treatment can be deadly. In a tragic case from Milwaukie, Oregon, a 26-year-old man named Jean Descamps died from an overdose shortly after being discharged from a hospital. Despite being in a vulnerable state, hospital staff dismissed his condition, leading to his untimely death. This incident highlights a broader issue where addiction patients are often met with suspicion and hostility rather than receiving the necessary care. Many healthcare providers still avoid offering science-based addiction treatments, leaving millions without the help they need. This reluctance to treat addiction as a medical condition rather than a moral failing continues to have severe consequences for patients across the United States. THC medication shows promise for PTSD nightmares. A new study reveals that a prescription form of THC helped more than a third of PTSD patients eliminate recurring trauma-related nightmares after ten weeks of treatment. These nightmares are among the most distressing symptoms of PTSD, often leading to severe sleep deprivation. The study's findings suggest that THC could offer a long-awaited treatment option for those struggling with this debilitating condition. As research continues, this could pave the way for more effective management of PTSD symptoms, improving the quality of life for many affected individuals. Most U.S. doctors avoid treating addiction, leaving millions vulnerable. Despite the ongoing public health crisis, many healthcare providers in the United States continue to turn away patients with alcohol and drug addiction. This avoidance persists even though effective, science-based medications are available. The stigma surrounding substance use disorders remains a significant barrier to treatment, with many doctors and nurses still viewing addiction through a lens of moral judgment rather than as a medical condition. This widespread reluctance to provide appropriate care leaves millions of individuals without the support they need to recover. Cambodia becomes the first Asian country to hit an elusive HIV target. Cambodia has achieved the global 95–95–95 HIV targets, becoming the first country in Asia to do so. This means that 95% of people living with HIV in Cambodia know their status, 95% of those diagnosed are receiving treatment, and 95% of those on treatment have achieved viral suppression. This milestone demonstrates the power of community leadership and effective public health strategies in combating HIV. Cambodia's success offers a model for other countries striving to meet these ambitious targets by 2030. An osteoporosis drug blocks spinal damage in a new study. Researchers have discovered that a drug already used for osteoporosis can block spinal damage in zebrafish models of human disc disease. The study found that genetic changes can lead to mineral buildup and spinal fusion, similar to human conditions. By targeting fat metabolism and using the osteoporosis drug, researchers were able to reduce this damage. This finding opens up exciting possibilities for future treatments of back pain and spinal disorders, potentially offering relief to millions suffering from these conditions. ADHD youth reveal insights on transitioning to adulthood. A meta-ethnography of 805 young people with ADHD across 11 countries highlights the importance of reshaping environments, relationships, and services to better support their transition to adulthood. Rather than focusing on 'fixing' the individuals, the study emphasizes the need for systems that meet young people where they are. This approach could significantly improve outcomes for those with ADHD, helping them navigate the complex changes of late adolescence and early adulthood more effectively. ## Feature Story Nearly half of dementia cases may be linked to modifiable risks. A long-term brain study has found that common risk factors such as smoking, high blood pressure, heart disease, and high blood lipids are strongly linked to vascular dementia. These findings suggest that healthier lifestyle choices could help delay dementia by reducing several harmful brain changes simultaneously. The World Health Organization has released updated guidelines to help countries prevent or delay dementia onset, emphasizing the importance of addressing these modifiable risks throughout life. With over 57 million people living with dementia worldwide, and nearly 10 million new cases each year, the potential to prevent or delay nearly half of these cases is significant. The ...
