In order to facilitate this process, bone marrow and stem cell registries have been established to genetically catalog potential donors and can be used to find matches for patients in need. Given the wide genetic variability in populations and significant ethnic disparities in donor registries worldwide, there are substantial gaps in the availability of compatible unrelated stem cell donors. Limited understanding of the procedures involved in stem cell donation, along with potential misconceptions of associated risks, may discourage prospective donors. Many people are unaware that there are two established methods for stem cell donation from adult donors, either through bone marrow harvest or—more commonly— through peripheral blood stem cell harvest. This evidence-based commentary explores these two procedures, deconstructs misconstrued fears associated with stem cell donation, and subsequently encourages readers to consider registering as stem cell donors.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78109879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nine researchers participated in semi-structured interviews. The interviews were analyzed using a grounded theory approach. Access was cited as a major challenge to recruitment. Successful strategies involved forming positive relationships with participants, hospitals, and community partners. Those who agreed to participate were often of high socioeconomic status or had a connection to McMaster University. Interviewed researchers believed that collaborating with colleagues, communicating directly with new mothers, and establishing partnerships with individuals in related professional fields were all effective in facilitating infant recruitment. As recruiting infants for non-invasive studies remains challenging, this study aims to assist researchers in finding successful strategies.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74335298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Carbapenem resistance by Enterobacteriaceae can occur by many mechanisms, including the production of a metallo-beta-lactamase or a carbapenemase (such as Klebsiella pneumoniae carbapenemase, KPC) which can be transmitted from one Enterobacteriaceae to another. Metallo-beta-lactamases such as New Delhi metallo-beta-lactamase (NDM), are more common outside the United States. CRE can also have additional resistance mechanisms such as Verona Integron-Mediated Metallo-B-lactamase (VIM) and OXA-48, which enable organisms to be non-susceptible to many other classes of commonly used antibiotics.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85956408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Infections caused by P. aeruginosa can be nearly untreatable because of its multidrug-resistance. One of the characteristics of P. aeruginosa that helps it survive in high drug concentrations is its ability to form biofilms–large communities of cells encompassed by extracellular polymeric substances that defend against many antibiotics. In fact, sub-minimum inhibitory concentrations of antibiotics stimulate biofilm production. This project aims to identify genes associated with biofilm induction in P. aeruginosa by screening a transposon mutant library for mutants that fail to show increased biofilm production when exposed to sub-minimum inhibitory concentrations of cefixime, tobramycin, and thiostrepton. So far, we have identified one gene, PA2714, that encodes a predicted molybdopterin oxidoreductase required for biofilm production. Because of the strong association between biofilm production and antibiotic tolerance in P. aeruginosa, the gene identified in this screen may be a useful therapeutic target for novel antimicrobialsthat can disrupt biofilm formation.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"28 1","pages":"19-22"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88185024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ongoing investigations into FMT’s efficacy in the treatment of other conditions, such as multiple sclerosis and inflammatory bowel disease, may expand the application of FMT to a myriad of diseases. Nonetheless, challenges regarding biosafety concerns and public perception need to be addressed before FMTs can be considered for broaderapplications.","PeriodicalId":22813,"journal":{"name":"The Meducator","volume":"19 1","pages":"23-26"},"PeriodicalIF":0.0,"publicationDate":"2018-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85718806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this surgery was unlike any other that had been completed before. 1 Morton’s stage was the local surgical amphitheater in the Massachusetts General Hospital, and his main prop was the ether, a novel substance that promised to alleviate pain in an unprecedented manner. Within the amphitheater, scientists, dentists, and doctors eagerly awaited the awakening of Morton’s patient after the surgery. To everyone’s delight, after awakening, the patient announced that he did not feel any pain during the operation.
