Characterizations of novel broad-spectrum lytic bacteriophages Sfin-2 and Sfin-6 infecting MDR Shigella spp. with their application on raw chicken to reduce the Shigella load
The evidence and prevalence of multidrug-resistant (MDR) Shigella spp. poses a serious global threat to public health and the economy. Food- or water-borne MDR Shigella spp. demands an alternate strategy to counteract this threat. In this regard, phage therapy has garnered great interest from medical practitioners and researchers as a potential way to combat MDR pathogens. In this observation, we isolated Shigella phages from environmental water samples and tested against various clinically isolated MDR Shigella spp. In this study, we have defined the isolation and detailed physical and genomic characterizations of two phages Sfin-2 and Sfin-6 from environmental water samples. The phages exhibited potent lytic activity against Shigella flexneri, Shigella dysenteriae, and Shigella sonnei. They showed absorption within 5ā10 min, a burst size ranging from ~74 to 265 PFU/cell, and a latent period of 5ā20 min. The phages were stable at a broad pH range and survived an hour at 50Ā°C. The purified phages Sfin-2 and Sfin-6 belong to the Siphoviridae family with an isometric head (64.90 Ā± 2.04 nm and 62.42 Ā± 4.04 nm, respectively) and a non-contractile tail (145 Ā± 8.5 nm and 148.47 Ā± 14.5 nm, respectively). The in silico analysis concluded that the size of the genomic DNA of the Sfin-2 phage is 50,390 bp with a GC content of 44.90%, while the genome size of the Sfin-6 phage is 50,523 bp with a GC content of 48.30%. A total of 85 and 83 putative open reading frames (ORFs) were predicted in the Sfin-2 and Sfin-6 phages, respectively. Furthermore, a comparative genomic and phylogenetic analysis revealed that both phages represented different isolates and novel members of the T1-like phages. Sfin-2 and Sfin-6 phages, either individually or in a cocktail form, showed a significant reduction in the viable Shigella count on raw chicken samples after 72 h of incubation. Therefore, these results indicate that these phages might have a potential role in therapeutic approaches designed for shigellosis patients as well as in the biological control of MDR Shigella spp. in the poultry or food industry during the course of meat storage
Pathology Informatics Essentials for Residents: A Flexible Informatics Curriculum Linked to Accreditation Council for Graduate Medical Education Milestones (a secondary publication)*
Context: Recognition of the importance of informatics to the practice of pathology has surged. Training residents in pathology
informatics has been a daunting task for most residency programs in the United States because faculty often lacks experience and
training resources. Nevertheless, developing resident competence in informatics is essential for the future of pathology as a
specialty.
Objective: To develop and deliver a pathology informatics curriculum and instructional framework that guides pathology
residency programs in training residents in critical pathology informatics knowledge and skills, and meets Accreditation Council
for Graduate Medical Education Informatics Milestones.
Design: The College of American Pathologists, Association of Pathology Chairs, and Association for Pathology Informatics
formed a partnership and expert work group to identify critical pathology informatics training outcomes and to create a highly
adaptable curriculum and instructional approach, supported by a multiyear change management strategy.
Results: Pathology Informatics Essentials for Residents (PIER) is a rigorous approach for educating all pathology residents in
important pathology informatics knowledge and skills. PIER includes an instructional resource guide and toolkit for incorporating informatics training into residency programs that vary in needs, size, settings, and resources. PIER is available at http://
www.apcprods.org/PIER (accessed April 6, 2016).
Conclusions: PIER is an important contribution to informatics training in pathology residency programs. PIER introduces
pathology trainees to broadly useful informatics concepts and tools that are relevant to practice. PIER provides residency program
directors with a means to implement a standardized informatics training curriculum, to adapt the approach to local program
needs, and to evaluate resident performance and progress over time
Evaluation of computerized health management information system for primary health care in rural India
<p>Abstract</p> <p>Background</p> <p>The Comprehensive Rural Health Services Project Ballabgarh, run by All India Institute of Medical Sciences (AIIMS), New Delhi has a computerized Health Management Information System (HMIS) since 1988. The HMIS at Ballabgarh has undergone evolution and is currently in its third version which uses generic and open source software. This study was conducted to evaluate the effectiveness of a computerized Health Management Information System in rural health system in India.</p> <p>Methods</p> <p>The data for evaluation were collected by in-depth interviews of the stakeholders i.e. program managers (authors) and health workers. Health Workers from AIIMS and Non-AIIMS Primary Health Centers were interviewed to compare the manual with computerized HMIS. A cost comparison between the two methods was carried out based on market costs. The resource utilization for both manual and computerized HMIS was identified based on workers' interviews.</p> <p>Results</p> <p>There have been no major hardware problems in use of computerized HMIS. More than 95% of data was found to be accurate. Health workers acknowledge the usefulness of HMIS in service delivery, data storage, generation of workplans and reports. For program managers, it provides a better tool for monitoring and supervision and data management. The initial cost incurred in computerization of two Primary Health Centers was estimated to be Indian National Rupee (INR) 1674,217 (USD 35,622). Equivalent annual incremental cost of capital items was estimated as INR 198,017 (USD 4213). The annual savings is around INR 894,283 (USD 11,924).</p> <p>Conclusion</p> <p>The major advantage of computerization has been in saving of time of health workers in record keeping and report generation. The initial capital costs of computerization can be recovered within two years of implementation if the system is fully operational. Computerization has enabled implementation of a good system for service delivery, monitoring and supervision.</p
Clinical Informatics Training During Emergency Medicine Residency: The University of Michigan Experience
Clinical informatics (CI) is a rich field with longstanding ties to resident education in many clinical specialties, although a historic gap persists in emergency medicine. To address this gap, we developed a CI track to facilitate advanced training for senior residents at our 4āyear emergency medicine residency. We piloted an affordable projectābased approach with strong ties to operational leadership at our institution and describe specific projects and their outcomes. Given the relatively low cost, departmental benefit, and unique educational value, we believe that our model is generalizable to many emergency medicine residencies. We present a pathway to defining a formal curriculum using Kernās framework.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/167847/1/aet210518.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/167847/2/aet210518_am.pd
