The PrePex circumcision device causes ischemic necrosis of the foreskin, raising concerns of anaerobic overgrowth. We compared the subpreputial microbiome of 2 men 7 days after PrePex device placement to that of 145 uncircumcised men in Rakai, Uganda, using 16S ribosomal (rRNA) RNA gene-based quantitative polymerase chain reaction analysis and sequencing. PrePex users had higher absolute abundance of all bacteria than uncircumcised men (P = .001), largely due to increased numbers of the following anaerobes: Porphyromonas (5.2 × 10(7) 16S rRNA gene copies/swab in the PrePex group and 1.1 × 10(6) 16S rRNA gene copies/swab in uncircumcised men; P = .002), Peptoniphilus (1.0 × 10(7) and 1.8 × 10(6) 16S rRNA gene copies/swab, respectively; P < .05), Anaerococcus (1.0 × 10(7) and 1.1 × 10(6) 16S rRNA gene copies/swab, respectively; P < .001), and Campylobacter ureolyticus (1.7 × 10(5) and 1.6 × 10(7)16S rRNA gene copies/swab, respectively; P < .001). The PrePex-associated increase in anaerobes may account for unpleasant odor and a possible heightened risk of tetanus.

Unlabelled: The complex (MAC) is a common causative agent causing nontuberculous mycobacterial (NTM) pulmonary disease worldwide. Whole-genome sequencing was performed on a total of 203 retrospective MAC isolates from respiratory specimens. Phylogenomic analysis identified eight subspecies and species.

Background: Diabetes with its highly prevalence has become a major contributor to the burden of health care costs worldwide. Recent unequivocal evidence has revealed a bidirectional link between oral health and diabetes. In this study, the effects of the Oral Health Promotion Program (OHPP) on oral hygiene, oral health-related quality of life and glycated haemoglobin (HbA1c) levels in diabetic elderly were examined.
