Tuberculosis-Associated Hemophagocytic Lymphohistiocytosis: Diagnostic Challenges and Determinants of Outcome.

Background: Tuberculosis (TB) can induce secondary hemophagocytic lymphohistiocytosis (HLH), a severe inflammatory syndrome with high mortality. We integrated all published reports of adult HIV-negative TB-associated HLH (TB-HLH) to define clinical characteristics, diagnostic strategies, and therapeutic approaches associated with improved survival.

Methods: PubMed, Embase, and Global Index Medicus were searched for eligible records.

Zika virus infection in European travellers returning from Thailand in 2022: A GeoSentinel case series.

Zika virus is a mosquito-borne flavivirus which caused major epidemics in the Pacific and the Americas between 2013 and 2015. International travellers have previously acted as a sentinel population for Zika virus transmission in endemic areas, where local transmission may be incompletely captured by local surveillance systems. We report five recent European travellers returning from Thailand with Zika virus infection, highlighting the risk of ongoing endemic transmission in this popular tourist destination.

Hepatocellular Carcinoma in Perinatally Acquired HIV and HBV Coinfection: A Case Report.

This report describes a case of hepatocellular carcinoma in an adolescent with perinatally acquired HIV and hepatitis B virus coinfection, arising despite more than a decade of suppressive antiretroviral therapy for both HIV and hepatitis B virus. This case raises important questions regarding optimal hepatocellular carcinoma screening in this high-risk group and the oncogenic potential of even very well-controlled viral infection.

Identification of targets of tumor suppressor microRNA-34a using a reporter library system.

miRNAs play critical roles in various biological processes by targeting specific mRNAs. Current approaches to identifying miRNA targets are insufficient for elucidation of a miRNA regulatory network. Here, we created a cell-based screening system using a luciferase reporter library composed of 4,891 full-length cDNAs, each of which was integrated into the 3' UTR of a luciferase gene.
