Identifying missed prevention opportunities: maternal and congenital syphilis in hospital records and birth certificates in California from 2011 to 2021.

Frankeberger Jessica et al.

Journal of perinatology : official journal of the California Perinatal Association โ€ข 2026

# Clinical Summary Among California births from 2011 to 2021, congenital syphilis occurred in 0.06% of cases where mothers had syphilis, with public insurance identified as a risk factor for transmission. The study identified missed prevention opportunities by examining gaps between maternal syphilis documentation and actual congenital syphilis cases, suggesting inconsistent screening or treatment during pregnancy.

Effect of Nonmedical Cannabis Legalization and Exposure to Retail Stores on Cannabis Harms : A Quasi-experimental Study.

Friesen Erik Loewen et al.

Annals of internal medicine โ€ข 2026

# Clinical Summary After Canada legalized nonmedical cannabis in 2018, researchers found that higher exposure to cannabis retail stores was associated with increased emergency department visits related to cannabis use in Ontario. The study suggests that limiting the density of cannabis retail locations could be an effective public health strategy to reduce cannabis-related harms in the community.

Substance use and menopausal hormone therapy: Treatment initiation and interruption among US women with and without HIV, 2008-2019.

Knittel Andrea K et al.

International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics โ€ข 2026

# Clinical Summary Women with substance use were less likely to initiate menopausal hormone therapy for moderate-to-severe hot flashes compared to those without substance use, regardless of HIV status. Treatment interruptions were more common among women with active substance use, suggesting that substance use may be a barrier to consistent management of menopausal symptoms.

Neuroprotective Role of Cannabinoid CB1 and GPR55 Receptors in a Cell Model of Multiple Sclerosis.

Martรญnez-Pinilla Eva et al.

Molecular neurobiology โ€ข 2026

# Clinical Summary Researchers found that CB1 and GPR55 receptors, which are part of the body’s endocannabinoid system, protect nerve cells and support oligodendrocytes (the cells that insulate nerve fibers) in cell models simulating multiple sclerosis. These receptors represent a potential new treatment approach since current MS medications mainly suppress the immune system but do not effectively repair nerve damage or restore the protective myelin coating.

Rates and predictors of postdischarge opioid-free analgesia after elective colorectal surgery: A prospective cohort study.

Pook Makena et al.

Surgery โ€ข 2026

This study found that a significant proportion of patients undergoing elective colorectal surgery can manage postdischarge pain without opioids, though rates and predictors of opioid-free analgesia vary based on patient and care characteristics. The research identified specific patient and clinical factors associated with successful opioid-free pain management after colorectal surgery, providing insights to guide safer postoperative pain control strategies.

Reducing severe breathlessness with dronabinol in the group of patients with severe and very severe chronic obstructive pulmonary disease (BONG): a randomised, double-blinded, placebo-controlled, crossover study in an outpatient clinic in Denmark – a study protocol.

Wolsing Sofie Krogh et al.

BMJ open โ€ข 2026

This is a study protocol describing a planned clinical trial rather than completed research with results. The study will test whether dronabinol, a synthetic cannabinoid, can reduce severe breathlessness in patients with advanced COPD who remain symptomatic despite standard treatments, using a randomized double-blinded design with 30 participants in Denmark.

Machine learning identifies traumatic experiences as being associated with auditory verbal hallucinations in both a non-clinical population and individuals diagnosed with psychosis.

Ostojic Dijana et al.

Psychiatry research โ€ข 2026

# Clinical Summary Researchers used machine learning to analyze data from over 130,000 UK Biobank participants and found that traumatic experiences were the strongest predictor of hearing voices (auditory verbal hallucinations) in both people with psychosis and the general population. This finding suggests that trauma is a significant shared risk factor for voice-hearing experiences across different groups, regardless of psychiatric diagnosis.
