An Assessment of Individual Preference for a Novel Capillary Blood Collection System.

Purpose: Typical barriers to venous blood collection for wellness testing include discomfort, time spent, and collection site accessibility. This study assessed individuals' experience, satisfaction, and preference associated with a FDA-cleared blood-collection device, the BD MiniDraw™ Capillary Blood Collection System (BD MiniDraw), in retail locations. Patients and Methods: A total of 113 individuals (≥18 years) with venous blood collection experience were enrolled; 107 completed the study. A pre-collection survey gathered information on demographics and past experiences with healthcare and venous blood collection settings. BD MiniDraw collection was conducted at three retail sites (two pharmacies and one grocery store) by trained healthcare workers using the Babson BetterWay blood testing service model. A follow up survey was performed two weeks later to determine experience with, and preference for, BD MiniDraw in terms of staff professionalism, blood collection location, blood collection time, and staff trustworthiness. Results: Among the 107 participants, 74 (69%) were female and 33 (31%) were male; the mean age was 49 years (range=18-71 years). Sixty-six (62%) participants viewed their prior venipuncture experience as "somewhat" or "very" positive. Following capillary collection, 96 (90%) participants expressed a "somewhat" or "very" positive experience with BD MiniDraw at a retail location. In particular, "very satisfied" responses were given for location (87/107; 81%) and collection time (78/1407; 73%). In a subset of respondents (n=89), those reasons (location and time savings) were most frequent for likelihood of future use. Ninety-nine participants (92%) rated the retail blood collection team as "very" or "extremely" trustworthy. Overall, 90 participants (84%) "strongly preferred" (56/107; 52%), "somewhat preferred" (14/107; 13%), or had "no preference" (20/107; 19%) for BD MiniDraw, compared to traditional venous blood collection. Conclusion: Most participants conveyed a preference for BD MiniDraw, primarily based on the blood collection retail location, perceived time savings, and professionalism and trustworthiness of the staff.

The role of blood testing in prevention, diagnosis, and management of chronic diseases: A review.

Blood tests are vital to prevention, diagnosis, and management of chronic diseases. Despite this, it can be challenging to construct a comprehensive view of the clinical importance of blood testing because relevant literature is typically fragmented across different disease areas and patient populations. This lack of collated evidence can also make it difficult for primary care providers to adhere to best practices for blood testing across different diseases and guidelines. Thus, this review article synthesizes the recommendations for, and importance of, blood testing across several common chronic conditions encountered in primary care and internal medicine, including cardiovascular diseases, diabetes mellitus, chronic kidney disease, vitamin D deficiency, iron deficiency, and rheumatoid arthritis. Future research is needed to continue improving chronic disease management through clearer dissemination and awareness of clinical guidelines among providers, and better access to blood testing for patients (e.g., via pre-visit laboratory testing).

A comprehensive review of the diagnosis and management of prosthetic joint infections in the absence of positive cultures.

The diagnosis and management of prosthetic joint infections (PJI) with negative cultures remains an enigma without clear definitions and guidelines for its management. In contrast, the literature offers guidelines to the diagnosis and management of culture positive prosthetic joint infections as noted in both the infectious disease literature and the orthopedic literature. This paper outlines the current state of knowledge of PJI with negative cultures and summarizes the recommendations for the work up and management of this condition. In addition, we propose a simple algorithm that clinicians may find useful for the management of PJI with negative cultures. This algorithm has not been validated with data at this point, but can be applied to practice to help direct the management and diagnosis of prosthetic joint infections in the absence of positive cultures.

Extended-Spectrum Beta-Lactamase Infections in Orthopedic-Related Devices and Prosthetic Joints.

Extended-spectrum beta-lactamase-producing Enterobacteriaceae have increasingly become a public health issue in a variety of infections, including urinary tract infections and postoperative infections. The complications that occur due to these organisms in bone, joint, and prosthetic joints have not been well defined. This study reviewed the clinical characteristics, risk factors, and outcomes of patients with extended-spectrum beta-lactamase-producing Enterobacteriaceae infections of prosthetic joints or orthopedic-related hardware. Six infections met the inclusion criteria that resulted in a 100% failure rate when the hardware or prosthetic joint was not replaced initially. However, when the hardware or prosthetic joint was replaced, all of the patients did well. The use of carbapenems remains effective in these cases. [Orthopedics. 2016; 39(4):e668-e673.].

Coccidioidomycosis involving the cranium: a case report and review of current literature.

We report a case of Coccidioidomycosis of the cranium that presented as a cystlike structure with adjoining bone destruction in a 40-year-old patient with underlying rheumatoid arthritis that was treated with a combination of lipid amphotericin B and longterm fluconazole. We also discuss the common risk factors and presentations of this unusual extra-pulmonary form of Coccidioidomycosis.

Gastrointestinal Mucormycosis Resulting in a Catastrophic Outcome in an Immunocompetent Patient.

We present a case of a middle-aged female who was admitted to the hospital with a respiratory infection and subsequently developed an acute surgical abdomen secondary to a perforated viscous. She was found to have mucormycosis of the intestinal tract and eventually succumbed to the sequelae of the infection.

Lin28b is sufficient to drive liver cancer and necessary for its maintenance in murine models.

Lin28a/b are RNA-binding proteins that influence stem cell maintenance, metabolism, and oncogenesis. Poorly differentiated, aggressive cancers often overexpress Lin28, but its role in tumor initiation or maintenance has not been definitively addressed. We report that LIN28B overexpression is sufficient to initiate hepatoblastoma and hepatocellular carcinoma in murine models. We also detected Lin28b overexpression in MYC-driven hepatoblastomas, and liver-specific deletion of Lin28a/b reduced tumor burden, extended latency, and prolonged survival. Both intravenous siRNA against Lin28b and conditional Lin28b deletion reduced tumor burden and prolonged survival. Igf2bp proteins are upregulated, and Igf2bp3 is required in the context of LIN28B overexpression to promote growth. Therefore, multiple murine models demonstrate that Lin28b is both sufficient to initiate liver cancer and necessary for its maintenance.
