We read with interest the article by Turse et al.1 The authors report, in a retrospective study, that deep sedation (DS) had no benefit compared with moderate sedation (MS) for adenoma detection rate (ADR) and polyp detection rate (PDR) in average-risk patients undergoing screening colonoscopy for colorectal cancer. The study populations were similar for both groups, including relatively healthy patients. A highlighted strength of the study was that the focus on average-risk patients examined at the same center minimized possible confounding factors of prior investigations.
Colonoscopy screening comes with a significant cost. If you sum up the costs due to health care personnel, endoscopy technology, facilities, and histopathology, colonoscopy is among the most expensive diagnostic procedures, with estimates comparable with whole-body CT or magnetic resonance imaging. When these costs are projected at population level, the absolute magnitude is exceptional, inasmuch as it is estimated to correspond to an annual gross expenditure of more than U.S. $775 million.1
CONCLUSION: Ocular manifestations of Crohn's disease are polymorphic. Colonic or ileocolic localisation, as well as the activity of the bowel disease, have been identified as risk factors for ocular involvement. PMID: 32950292 [PubMed - as supplied by publisher]
Conclusion: ZnO nanocoating may improve the antibacterial effects of NiTi wires and reduce the frictional resistance. Coating may be implanted in orthodontic practice for faster and safer treatment.RESUMO Objetivos: Avaliar o efeito do nanorrevestimento de óxido de zinco (ZnO) sobre as propriedades mecânicas e propriedades antibacterianas de fios ortodônticos de NiTi. Métodos: Fios 0,016 ” x 0,022 ” de NiTi foram revestidos com nanopart ículas de ZnO por meio de um método de deposição eletroquímica com um sistema de três eletrodos a 0,1M Zn(NO3)...
Ionizing radiation (IR) is lethal to most organisms at high doses, damaging every cellular macromolecule via induction of reactive oxygen species (ROS). Utilizing experimental evolution and continuing previous work, we have generated the most IR-resistant Escherichia coli populations developed to date. After 100 cycles of selection, the dose required to kill 99% the four replicate populations (IR9-100, IR10-100, IR11-100, and IR12-100) has increased from 750 Gy to approximately 3,000 Gy. Fitness trade-offs, specialization, and clonal interference are evident. Long-lived competing sub-populations are present in three of the...
kungo Public schools in most rural areas of South Africa depend on untreated groundwater due to unreliable water supply by the municipalities. This has the potential to cause water-related health problems to school children. Temperature, pH, and electrical conductivity (EC) were measured in situ. Chemical (fluoride, chloride, sulphate, phosphate, nitrate, magnesium, calcium, sodium, and potassium) and microbial (Escherichia coliform (E. coli), Salmonella typhimurium, and Shigella flexneri) water quality parameters were analysed in groundwater samples from 10 public schools in Vhuronga 1 to determine suitability for use...
