Introduction: Since 2013, the European Testing Week (ETW) awareness campaign has become a key regional event influencing testing efforts for HIV, viral hepatitis, and sexually transmitted infections (STIs) through participation of 720 organizations. Here, we report on a survey from May to June 2022 aimed at assessing the participant-reported impact of the campaign.
Methods: All past and current participating organizations were asked to complete an online questionnaire between 12 May and 17 June 2022.
Kaposi's sarcoma-associated herpesvirus (KSHV) is a member of the Gammaherpesvirus subfamily that encodes several viral proteins with intrinsic E3 ubiquitin ligase activity or the ability to hijack host E3 ubiquitin ligases to modulate the host's immune response and to support the viral life cycle. This review focuses specifically on how the immediate-early KSHV protein RTA (replication and transcription activator) hijacks the host's ubiquitin-proteasome pathway (UPP) to target cellular and viral factors for protein degradation to allow for robust lytic reactivation. Notably, RTA's targets are either potent transcription repressors or they are activators of the innate and adaptive immune response, which block the lytic cycle of the virus.

Using the current consensus definition of late HIV presentation ('presenting for care with a CD4 count < 350 cells/μL or an AIDS-defining event, regardless of CD4 count') these individuals would be incorrectly assigned as being diagnosed late.
Methods: In spring 2022, a European expert group convened to revise the current late HIV presentation consensus definition.
The immediate early viral protein replication and transcription activator (RTA) of Kaposi's sarcoma-associated herpesvirus (KSHV) is essential for activating the lytic cycle of KSHV. RTA induces the KSHV lytic cycle by several mechanisms, acting as a viral transcription factor that directly induces viral and host genes and acting as a viral E3 ubiquitin ligase by degrading host proteins that block viral lytic replication. Recently, we have characterized the global gene expression changes in primary effusion lymphoma (PEL) upon lytic reactivation of KSHV, which also led to the identification of rapidly downregulated genes such as ID2, an inhibitor of basic helix-loop-helix transcription factors.

Epidemiological data are primarily available from national HIV case surveillance systems that rarely capture information on sex work, gender identity or imprisonment. Surveillance of HIV prevalence in key populations often occurs as independent studies with no established mechanism for collating such information at the European level.

Within the EU funded Joint Action INTEGRATE, this paper examined the feasibility and impact of expanding integrated testing for HIV, hepatitis C (HCV), chlamydia, gonorrhoea and/or syphilis in four community-based pilots through targeted interventions in Croatia, Italy and Poland and the Spring European Testing Week since community settings are key in detecting new infections and reaching key populations.
Methods: Pilots led by local INTEGRATE partners prioritised testing for other infections or key populations.
Dedifferentiated liposarcoma (DDLS) is a high-grade sarcoma that usually arises from a well-differentiated liposarcoma, which most commonly presents as a retroperitoneal mass. DDLS involving the colon is extremely rare, and only a few cases have been reported. We present a case of a DDLS that was found in the cecum and adjacent mesentery.

We analyse 98 responses from secondary care (n = 36), community testing sites (n = 52) and national level (n = 10). Compared to pre-COVID-19, 95% of respondents report decreased testing volumes during March-May and 58% during June-August 2020.

The study synthesizes recent evidence on HIV testing strategies adopted in health care settings in the European Union/European Economic Area (EU/EEA).
Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed and systematic searches were run in five databases (2010-2017) to identify studies describing HIV testing interventions in health care settings in the EU/EEA.
Objectives: In recent years, new technologies and new approaches to scale up HIV testing have emerged. The objective of this paper was to synthesize the body of recent evidence on strategies aimed at increasing the uptake and coverage of HIV testing outside of health care settings in the European Union (EU)/European Economic Area (EEA).
Methods: Systematic searches to identify studies describing effective HIV testing interventions and barriers to testing were run in five databases (2010-2017) with no language restrictions; the grey literature was searched for similar unpublished studies (2014-2017).
Forensic DNA samples may include the presence of PCR inhibitors, even after extraction and purification. Studies have demonstrated that metal ions, co-purified at specific concentrations, inhibit DNA amplifications. Metal ions are endogenous to sample types, such as bone, and can be introduced from environmental sources.

Objective: To determine the effects of chlorhexidine gluconate (CHG) on skin inflammation and stratum corneum barrier integrity at peripherally inserted central catheter (PICC) sites among patients in the neonatal intensive care setting.
Study Design: In a within-subject design, PICC sites with CHG plus semipermeable dressing (PICC) were compared with contralateral dressing sites and untreated controls among 40 neonates (gestational age 32.1+/-4.
Some studies suggest lesbian, gay, and bisexual (LGB) teens are at higher risk than peers for violence at home, in school, and in the community. That can bring them into the child welfare system or services for runaway and homeless teens. This study compared self-reported experiences of sexual and physical abuse based on sexual orientation and gender in seven population-based surveys of youth.

Methods: Distracter stimuli consisted of white noise, novel sounds, or a high frequency tone, with stimulus characteristics perceptually controlled. Task difficulty was varied as easy and hard by changing the pitch difference between the target and standard stimuli.
Congenital heart disease (CHD) affects 8 to 10 children out of every 1,000 live births. Of these, 2.2% have an abnormality associated with the spleen.

Differentiation among lines within a bottleneck size was significantly greater than predicted by drift in relation to the additive genetic variation for these traits within the founding population. Two models of nonadditive genetic variance were investigated to interpret these results, one involving dominance of allelic effects within loci and another incorporating multiplicative epistasis.
View Article and Find Full Text PDFEffects of a population bottleneck (founder-flush cycle) upon quantitative genetic variation of morphometric traits were examined in replicated experimental lines of the housefly founded with one, four or 16 pairs of flies. Heritability and additive genetic variances for eight morphometric traits generally increased as a result of the bottleneck, but the pattern of increase among bottleneck sizes differed among traits. Principal axes of the additive genetic correlation matrix for the control line yielded two suites of traits, one associated with general body size and another set largely independent of body size.

Since it is likely that family physicians will have more stepfamilies in their patient populations than in previous times, it is important for physicians to be aware of the characteristics of stepfamilies that are not present in intact nuclear families. These characteristic are (1) the formation of the stepfamily out of loss, (2) a common history of some family members, (3) a parent-child bond that predates the couple bond, (4) a biological parent elsewhere, (5) children as members of two households, and (6) the legal limitations of the step relationship.
