Researchers followed 712 participants from 2003 to 2019 and found that those who were always homeless had a much higher risk of hepatitis C, with 45 infections for every 100 person-years compared to just 7 for those who were always housed. This is important because it shows that having stable housing can significantly lower the risk of hepatitis C among young drug users. Who this helps: This helps young adults who inject drugs, especially those experiencing homelessness.

Bone reports

Mandair GS, Oest ME, Mann KA, Morris MD, Damron TA +1 more

Plain English
This study looked at how radiation therapy for soft tissue sarcomas affects different parts of the bone in mice. The researchers found that after radiation, the inner part of the bone changed more significantly compared to the outer parts, with some changes noticeable as soon as two weeks later. These changes in bone composition, which make bones weaker, can increase the risk of fractures in cancer patients treated with radiation, highlighting the importance of monitoring bone health in these individuals. Who this helps: This helps patients undergoing radiation therapy for cancer.

Drug and alcohol dependence

Morris MD, Mirzazadeh A, Evans JL, Briceno A, Coffin P +2 more

Plain English
This study looked at young adults in San Francisco who inject drugs and have hepatitis C to see how many received treatment with direct-acting antiviral medications. Out of 60 people identified, only 30 accepted a referral to treatment, just five actually started and completed it, but all five were cured. The findings highlight that many young people face barriers, such as fear of healthcare and competing life challenges, which prevent them from getting the help they need. Who this helps: This helps young adults with hepatitis C who inject drugs, as well as healthcare providers aiming to improve treatment access.

Mooney AC, Neilands TB, Giannella E, Morris MD, Tulsky J +1 more

Plain English
This study looked at how California's Proposition 47, which changed certain drug possession crimes from felonies to misdemeanors, affected the punishment severity across different counties. After Prop-47 passed, the likelihood of getting a felony conviction for drug possession dropped significantly—from 20% to 6%, a decline of 14 percentage points. The study found that counties with previously higher felony conviction rates saw the biggest changes, leading to more equal outcomes statewide, and there were no increases in felony convictions for other types of offenses. Who this helps: This benefits individuals arrested for drug offenses, as they face less severe punishments across California.

Hahn JA, Tully DC, Evans JL, Morris MD, Briceno A +3 more

Plain English
This study looked at how the level of hepatitis C virus (HCV) in the blood affects the spread of the virus among young adults who inject drugs. Researchers followed 69 high-risk individuals and found that there were 25 new HCV infections, with almost half linked to an injecting partner. They discovered that while the amount of virus in the blood of an infected person didn't impact the likelihood of spreading the virus, being newly infected significantly increased the risk of transmission. Who this helps: This helps young adults who inject drugs and healthcare providers working to reduce hepatitis C transmission.

Injecting-related trust, cooperation, intimacy, and power as key factors influencing risk perception among drug injecting partnerships.

2019

PloS one

Morris MD, Andrew E, Tan JY, Maher L, Hoff C +2 more

Plain English
This study examined how trust, cooperation, intimacy, and power dynamics between people who inject drugs influence their perceptions of risk when sharing needles and other injecting equipment. Researchers interviewed 27 individuals and found that these interpersonal factors impact how safe or risky partners feel about their drug use, with trust and cooperation often leading to lower perceived risks. This is important because understanding these personal relationships can help create better prevention strategies to reduce the spread of HIV and hepatitis C among drug users. Who this helps: This benefits patients who inject drugs and the healthcare providers working to support them.

PloS one

Page K, Evans JL, Hahn JA, Vickerman P, Shiboski S +1 more

Plain English
This study looked at how the age of injection partners and their knowledge of hepatitis C virus (HCV) status impacted the rate of HCV infections among young adults in San Francisco who inject drugs. Researchers found that the rate of new HCV infections was highest among those whose partners were mostly younger than 30 and who knew that at least one partner was HCV-positive, with an incidence rate of 58.9 new infections per 100 person-years. Understanding these patterns is crucial for developing better prevention strategies to stop the rising HCV rates in young people. Who this helps: This research benefits young adults who inject drugs, clinicians, and public health officials aiming to reduce HCV infections.

Journal of Raman spectroscopy : JRS

Mandair GS, Steenhuis P, Ignelzi MA, Morris MD

Plain English
This study looked at how well bone created in a lab using stem cells from mouse skulls compares to natural bone from newborn mice. After 28 days of growing the cells, the lab-made bone showed similar mineral quality to that of the mice but had less organized collagen structure. This is important because it helps scientists understand the potential of using stem cells for repairing bone defects, even though the lab-created bone isn't quite as strong as natural bone. Who this helps: This helps researchers and medical professionals working on bone repair treatments.
