Abstract

Men who have sex with men (MSM) account for more than two thirds of new HIV diagnoses annually. Sexual behavior that increases risk for onward transmission of HIV is associated with both alcohol and cannabis use. However, little is known about the influence of cannabis and alcohol co-use on engagement in condomless anal sex (CAS). The current study explored daily associations between substance use and CAS among HIV-positive MSM using a 42-day timeline followback interview (N = 101). Generalized estimating equation (GEE) logistic regression models were used to examine the association between cannabis and alcohol co-use and CAS at the sexual event while controlling for study site, condition, adherence to antiretroviral therapy, sex-related alcohol expectancies, and partner type. Participants provided data for 1052 sexual activity days, 60.7% of which involved CAS. Of 638 CAS days, 9.1% involved no substances, 72.0% involved either cannabis or alcohol use, and 18.9% involved cannabis and alcohol co-use. Results indicated that the odds of engaging in CAS were higher for sexual events in which cannabis and alcohol co-use occurred (aOR 2.98; 95% CI 1.27, 6.97) compared to events in which no substance use occurred (p = 0.012), but this relationship was no longer significant when cannabis and alcohol co-use was compared to single substance use (aOR 1.57; 95% CI 0.85, 2.90; p = 0.15). Future research should identify specific substance use (e.g., quantity) and partner characteristics (e.g., level of intoxication) that may uniquely influence the relationship between cannabis and alcohol co-use and condomless sex.

Knochenmarktransplantat als Chance für ältere AML-Patienten

Lange Zeit ist die Transplantation von hämatopoetischen Stammzellen nur bei jüngeren Patienten mit akuter myeloischer Leukämie praktiziert worden. Inzwischen profitieren auch Ältere davon. Ergebnisse einer Studie unterstützen dieses Vorgehen.

Nierenzellkarzinom: Kein Nachteil durch subkutan appliziertes Nivolumab

Die subkutane Applikation von Nivolumab ist nach Daten einer Phase-3-Studie ähnlich gut wirksam wie die intravenöse: Die Pharmakokinetik ist vergleichbar, die objektive Response war in der Studie sogar leicht besser als in der Gruppe mit Infusionen.

Vorteile für Androgenentzug plus Androgenrezeptorblockade

Für Männer mit metastasiertem hormonsensitivem Prostata-Ca. (mHSPC), die keine Hormonchemotherapie wollen oder vertragen, ist der Androgenentzug plus Darolutamid eine Alternative: Das Progressionsrisiko wird im Vergleich zum alleinigen Androgenentzug fast halbiert.

Mit Lidocain kommt der Darm nicht schneller in Schwung

Verzögertes Wiederanspringen der Darmfunktion ist ein Hauptfaktor dafür, wenn Patientinnen und Patienten nach einer Kolonresektion länger als geplant im Krankenhaus bleiben müssen. Ob man diesem Problem mit Lidocain vorbeugen kann, war Thema einer Studie.
