A large outbreak of Clostridium difficile‐associated disease with an unexpected proportion of deaths and colectomies at a teaching hospital following increased Fluoroquinolone use

BACKGROUND AND OBJECTIVE: Fluoroquinolones have not been frequently implicated as a cause of Clostridium difficile outbreaks. Nosocornial C. difficile infections increased from 2.7 to 6.8 cases per 1,000 discharges (P < .001). During the first 2 years of the outbreak, there were 253 nosocomial C difficile infections; of these, 26 resulted in colectomy and 18 resulted in death. We conducted an investigation of a large C. difficile outbreak in our hospital to identify risk factors and characterize the outbreak

Building a Personal Protective Equipment Monitor Team as Part of a Comprehensive COVID-19 Prevention Strategy

We instituted Personal Protective Equipment (PPE) Monitors as part of our care of COVID-19 patients in high-risk zones. PPE Monitors aided healthcare personnel (HCP) in donning and doffing, which contributed to nearly zero transmission of COVID-19 to HCP, despite their care of over 1400 COVID-19 patients

Cancer-Related Health Disparities in Women

Objectives. This article synthesizes information about cancer in 9 populations of minority women: Mexican American, Puerto Rican, Cuban American, African American, Asian American, Native Hawaiian, American Samoan, American Indian, and Alaska Native. Methods. Cancer registry data, social indicators, government sources, and published articles were searched for information on the background and cancer experience of these 9 racial/ethnic groups. Results. Approximately 35 million women in these racial/ethnic groups live in the United States, and their numbers are increasing rapidly. Since 1992, incidence rates for major cancer sites have slowed or decreased among these groups, but declines in mortality have not occurred or have been smaller than for Whites. Gaps in early detection have narrowed, but minority women still lag behind Whites. Smoking and obesity remain common in these populations. Conclusions. More culturally appropriate interventions and research are needed, and these efforts must involve the community and raise the quality of health services

Response to written feedback of clinical data within a longitudinal study:a qualitative study exploring the ethical implications

Background There is a growing ethical imperative to feedback research results to participants but there remains a striking lack of empirical research on how people respond to individualised feedback. We sought to explore longitudinal study participants’ response to receiving individual written feedback of weight-related and blood results, and to consider the balance of harms against benefits. Methods A qualitative study with face-to-face and telephone interviews conducted with 50 men and women who had participated in the fifth and most recent wave of the cohort study ‘West of Scotland Twenty-07’ and received a feedback letter containing body mass index (BMI), body fat percentage, cholesterol and glycated haemoglobin A1c (HbA1c) results. Results Expectations of, and response to, the feedback of their individual results varied. Whilst half of the participants were on the whole ‘pleased’ with their results or held neutral views, half reported negative responses such as ‘shock’ or ‘concern’, particularly in relation to the weight-related results. Participants who were overweight and obese used the most negative language about their results, with some being quite distressed and reporting feelings of powerlessness, low self-image and anxiety over future health. Nevertheless, some people reported having implemented lifestyle changes in direct response to the feedback, resulting in significant weight loss and/or dietary improvements. Others reported being motivated to change their behaviour. Age and gender differences were apparent in these narratives of behaviour change. Conclusions The potential harm caused to some participants may be balanced against the benefit to others. More evaluation of the impact of the format, content and means of individualised feedback of research findings in non-trial studies is required given the growing ethical imperative to offer participants a choice of receiving their results, and the likelihood that a high percentage will choose to receive them

Efficient, Long-term Hepatic Gene Transfer Using Clinically Relevant HDAd Doses by Balloon Occlusion Catheter Delivery in Nonhuman Primates

Helper-dependent adenoviral vectors (HDAd) are devoid of all viral coding sequences and are thus an improvement over early generation Ad because they can provide long-term transgene expression in vivo without chronic toxicity. However, high vector doses are required to achieve efficient hepatic transduction by systemic intravenous injection, and this unfortunately results in dose-dependent acute toxicity. To overcome this important obstacle, we have developed a minimally invasive method to preferentially deliver HDAd into the liver of nonhuman primates. Briefly, a balloon occlusion catheter was percutaneously positioned in the inferior vena cava to occlude hepatic venous outflow. HDAd was injected directly into the occluded liver via a percutaneously placed hepatic artery catheter. Compared to systemic vector injection, this approach resulted in substantially higher hepatic transduction efficiency using clinically relevant low vector doses and was accompanied by mild-to-moderate acute but transient toxicities. Transgene expression was sustained for up to 964 days. These results suggest that our minimally invasive method of delivery can significantly improve the vector's therapeutic index and may be a first step toward clinical application of HDAd for liver-directed gene therapy
