HIV outbreaks among people who inject drugs in Europe, North America and Israel

During 2011–16, HIV outbreaks occurred among people who inject drugs (PWID) in Canada (southeastern Saskatchewan), Greece (Athens), Ireland (Dublin), Israel (Tel Aviv), Luxembourg, Romania (Bucharest), Scotland (Glasgow), and USA (Scott County, Indiana). Factors common to many of these outbreaks included community economic problems, homelessness, and changes in drug injection patterns. The outbreaks differed in size (from under 100 to over 1000 newly reported HIV cases among PWID) and in the extent to which combined prevention had been implemented before, during, and after the outbreaks. Countries need to ensure high coverage of HIV prevention services and coverage higher than the current UNAIDS recommendation might be needed in areas in which short acting drugs are injected. In addition, monitoring of PWID with special attention for changing drug use patterns, risk behaviours, and susceptible subgroups (eg, PWID experiencing homelessness) needs to be in place to prevent or rapidly detect and contain new HIV outbreaks

Metastatic basal cell carcinoma: Prognosis dependent on anatomic site and spread of disease

PURPOSE: This review provides a description of the epidemiology and survival outcomes for cases with metastatic basal cell carcinoma (mBCC) based on published reports (1981-2011). METHODS: A literature search (MEDLINE via PubMed) was conducted for mBCC case reports published in English: 1981-2011. There were 172 cases that met the following criteria: primary BCC located on skin, metastasis confirmed by pathology and metastasis not resulting from direct tumour spread. From these, 100 mBCC cases with explicit information on follow-up time were selected for analysis. Survival analysis was conducted using Kaplan-Meier methods. RESULTS: Among 100 mBCC cases selected for analysis, including one case with Gorlin syndrome, 50% had regional metastases (RM) and 50% had distant metastases (DM). Cases with DM were younger at mBCC diagnosis (mean age, 58.0 versus 66.3years for RM; P=0.0013). Among 93 (of 100) cases with treatment information for metastatic disease, more DM cases received chemotherapy (36.2% versus 6.5% for RM), but more RM cases underwent surgery (87.0% versus 40.4% for DM). Among all 100 cases, median survival after mBCC diagnosis was 54months (95% confidence interval (CI), 24-72), with shorter survival in DM (24months; 95% CI, 12-35) versus RM cases (87months; 95% CI, 63-not evaluable). CONCLUSION: Cases with RM and DM mBCC may have different clinical courses and outcomes. Based on published reports, DM cases were younger at mBCC diagnosis, with shorter median survival than RM cases. This study provides a historical context for emerging mBCC treatments

Molecular and microscopic analysis of the gut contents of abundant rove beetle species (Coleoptera, Staphylinidae) in the boreal balsam fir forest of Quebec, Canada

Experimental research on beetle responses to removal of logging residues following clearcut harvesting in the boreal balsam fir forest of Quebec revealed several abundant rove beetle (Staphylinidae) species potentially important for long-term monitoring. To understand the trophic affiliations of these species in forest ecosystems, it was necessary to analyze their gut contents. We used microscopic and molecular (DNA) methods to identify the gut contents of the following rove beetles: Atheta capsularis Klimaszew­ski, Atheta klagesi Bernhauer, Oxypoda grandipennis (Casey), Bryophacis smetanai Campbell, Ischnosoma longicorne (Mäklin), Mycetoporus montanus Luze, Tachinus frigidus Erichson, Tachinus fumipennis (Say), Tachinus quebecensis Robert, and Pseudopsis subulata Herman. We found no apparent arthropod fragments within the guts; however, a number of fungi were identified by DNA sequences, including filamentous fungi and budding yeasts [Ascomycota: Candida derodonti Suh & Blackwell (accession number FJ623605), Candida mesenterica (Geiger) Diddens & Lodder (accession number FM178362), Candida railenensis Ramirez and Gonzáles (accession number JX455763), Candida sophie-reginae Ramirez & González (accession number HQ652073), Candida sp. (accession number AY498864), Pichia delftensis Beech (accession number AY923246), Pichia membranifaciens Hansen (accession number JQ26345), Pichia misumaiensis Y. Sasaki and Tak. Yoshida ex Kurtzman 2000 (accession number U73581), Pichia sp. (accession number AM261630), Cladosporium sp. (accession number KF367501), Acremonium psammosporum W. Gams (accession number GU566287), Alternaria sp. (accession number GU584946), Aspergillus versicolor Bubak (accession number AJ937750), and Aspergillus amstelodami (L. Mangin) Thom and Church (accession number HQ728257)]. In addition, two species of bacteria [Bradyrhizobium japonicum (Kirchner)Jordan (accession number BA000040) and Serratia marcescens Bizio accession number CP003942] were found in the guts. These results not only provide evidence of the consumer-resource relations of these beetles but also clarify the relationship between rove beetles, woody debris and fungi. Predominance of yeast-feeding by abundant rove beetles suggests that it may play an important role in their dietary requirements
