ASPERGILLUS MONITORING PROJECT IN A LARGE EDUCATIONAL HOSPITAL USING MOLECULAR

Our main object was to use a rapid and cheap molecular method for monitoring of Aspergillus infections and epidemiological approaches. Different molecular methods such as restriction fragment length polymorphism based on amplification of ribosomal RNA have been employed to identify Aspergilli in the level of species. The subject of our study was a group of hospitalized patients with clinical and subclinical signs of infection. All of the collected clinical specimens were transported to the medical mycology lab and examined for Aspergillus identification. Environmental specimens were collected from air and surfaces inspected for the Aspergillus hospital sources. A morphological study was firstly performed including; growth characteristics and microscopic features of Aspergillus species on mycological media for the identification. For the confirmation of Aspergillus isolates which similarly found in clinical and environmental sources, molecular method polymerase chain reaction/restriction fragment length polymorphism was carried out. From the mentioned specimens, 110 fungal isolates included Candida spp., Aspergillus spp. and other fungi. Among the clinical isolates of Aspergilli; Aspergillus flavus (47%), Aspergillus fumigatus (29.4%) and Aspergillus niger (23.6%) were the most frequent species respectively, and also environmental Aspergillus isolates were Aspergillus niger (43.7%), Aspergillus flavus (41.8%), Aspergillus fumigatus (14.7%). Because of facility in use, speed and high sensitivity of diagnosis, the polymerase chain reaction/restriction fragment length polymorphism with a single restriction enzyme was very useful in identification of medically important Aspergillus spp

Enabling informed policymaking for chronic kidney disease with a registry:Initiatory steps in Iran and the path forward

Objectives: Chronic kidney disease (CKD) registries have been used for more than half a century. Iran lacks a comprehensive registry to capture data of all CKD patients for an informed care planning and policy making. We aimed to identify the objectives and possible challenges for developing a CKD registry and also to define its minimum data set (MDS) in our healthcare context.Methods: This was a mixed-method study conducted in Iran from fall 2016 till summer 2017. The qualitative part included document analysis and 26 semi-structured interviews with 17 clinicians and managers involved in CKD care. This data was analyzed using the "grounded theory". Then, a modified Delphi survey was conducted. Percentages and mode values were used for analysis.Results: Our participants' leading interest in a CKD registry was centered on providing a coordinated, good-quality care for all CKD stages with particular emphasis to capture events and monitor trends for patients in earlier stages. They highlighted the required financial, technical and human resources as main challenges for a smooth registry implementation. Furthermore, a clinically oriented MDS comprising of 168 elements (with a majority having more than 90% agreement with mode 2) was extracted. It mainly collects demographics, medical history, encounter sessions, diagnostic examinations, medications, vaccinations and mortality data.Conclusions: We reported the initiatory steps taken to establish a CKD registry in an Iranian healthcare context. We focused on the information needs and priorities of our main stakeholders and based our intended registry on addressing those needs. We hope this approach will facilitate its endorsement and advance the efforts for a sustainable, good-quality CKD care. (C) 2018 Fellowship of Postgraduate Medicine. Published by Elsevier Ltd.

Molecular characterization of Aspergillus infections in an Iranian educational hospital using RAPD-PCR method

Objective(s): The nosocomial infections by Aspergillus species are associated with constructions and increased dust loads in hospital indoors. Our main object was to find the environmental sources of Aspergillus species causing hospital acquired infections. Materials and Methods: The clinical and environmental samplings were performed during 18 months from spring 2010 to summer 2011 in Imam educational hospital, Urmia, Iran. A morphological diagnosis was performed including microscopic characterization of isolated aspergillus from cultured specimens and polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) for the identification in the level of species. Random amplified polymorphic DNA – PCR RAPD-PCR using random primers for rDNA gene was performed to compare Aspergillus isolates of clinical cases with the relevant environmental sources. Results: Use of RAPD method resulted various differential patterns, so that some Aspergillus isolates from the clinical and hospital indoor were completely matched (matched pairs) and some other Aspergillus isolates were not matched.  In the case of matched pairs, Aspergillus niger and A. flavus isolated from broncoalveolar lavage and sinus discharge were relevant to those of air conditioner and walls surfaces, respectively. Conclusion: The hospital sources for the Aspergillus clinical isolates included air condition and walls. RAPD-PCR analysis can play a trivial role to find the hospital sources of Aspergillus clinical isolates

Patient empowerment through a user-centered design of an electronic personal health record: a qualitative study of user requirements in chronic kidney disease

Background: To improve chronic disease outcomes, self-management is an effective strategy. An electronic personal health record (ePHR) is a promising tool with the potential to support chronic patient’s education, counseling, and self-management. Fitting ePHRs within the daily practices of chronic care providers and chronic patients requires user-centered design approaches. We aimed to understand users’ needs and requirements in chronic kidney disease (CKD) care to consider in the design of an ePHR to facilitate its implementation, adoption, and use. Methods: A qualitative study was conducted in a major Iranian nephrology center including inpatient and outpatient settings in 2019. We conducted 28 semi-structured interviews with CKD patients, nurses, and adult nephrologists. To confirm or modify the requirements extracted from the interviews, a focus group was also held. Data were analyzed to extract especially those requirements that can facilitate implementation, adoption, and sustained use based on the PHR adoption model and the unified theory of acceptance and use of technology. Results: Participants requested an ePHR that provides access to up to date patient information, facilitates patient-provider communication, and increases awareness about patient individualized conditions. Participants expected a system that is able to cater to low patient e-health literacy and high provider workload. They requested the ePHR to include purposeful documentation of medical history, diagnostic and therapeutic procedures, tailored educational content, and scheduled care reminders. Messaging function, tailored educational content to individual patients’ conditions, and controlled access to information were highly valued in order to facilitate its implementation, adoption, and use. Conclusions: We focused on the ePHR’s content and functionalities in the face of facilitators and/or barriers envisioned for its adoption in nephrology care. Designers and implementers should value CKD patients’ needs and requirements for self-management such as providing personalized education and counseling (on the basis of their condition and risk factors), health literacy, and disease progression levels. The socio-technical aspects of care also need further attention to facilitate ePHR’s adoption

Clinical decision supports for brain-dead kidney allocation: a review study of requirements, challenges, and solutions

Introduction: With the change in the epidemiology of diseases, chronic kidney disease has shown a significant increase worldwide. Kidney transplantation is the optimal treatment option to improve patient quality of life. The main challenge in benefiting from a brain-dead patient's kidney is the selection of a right recipient in limited time. The purpose of this study was to review the requirements for designing and implementing clinical decision support systems for allocating brain-dead kidneys and the challenges facing them. Method: This scoping review was conducted by searching Scopus, PubMed, and Google scholar to find full-text English articles published until the end of 2021. The articles were analyzed based on the objectives of the study, the factors used in decision-making for allocation, the algorithms used in the decision-making process, and their outcome evaluations. Results: Two categories of medical (including the quality of the donated kidney) and equity/fairness factors were used in most allocation algorithms. However, the number of factors, the method, and the order of their application were different in different studies. Studies have reported different challenges but a positive impact using decision support systems. Conclusion: One of the main challenges in the proper management of kidney transplants from brain-dead donors is to have local, agreed-upon protocols and algorithms regarding the methods, order, and weight of each of the medical and equity factors in the proposed protocol. Algorithms based on scoring have mostly been favored. Therefore, the probability of using a decision support system on this base seems to be higher

The pathological evaluation of nonneoplastic kidney disorder in tumor nephrectomy specimens

Renal cell carcinoma (RCC) comprises 2%-3% of all visceral and 80%-85% of all adult kidney malignancies. Nephrectomy is the treatment of choice for renal tumors. The accurate pathological evaluation of nonneoplastic renal parenchyma in nephrectomy specimens is important for subsequent management. Eighty-two patients with RCC who underwent surgery at Imam Khomeini Hospital, Urmia, Iran, from April 2006 to February 2015 were studied. Paraffin blocks of the hospital archives were stained by hematoxylin and eosin (H and E) and periodic acid-Schiff staining. Microscopic examination was performed on nontumoral portions that were in the farthest possible distance from the tumor. Out of total 82 cases, 24 (29.3%) had normal renal parenchyma and 58 (70.7%) had pathological changes in renal parenchyma. The most frequent pathological findings were vascular sclerosis with parenchymal scarring and pyelonephritis. Other findings include focal and diffuse mesangial hypercellularity, eight; focal segmental glome-rulonephritis, five; membranoproliferative glomerulonephritis, three; and membranous glome-rulonephritis, two. Parenchymal scarring and vascular change included 36% of clear cell type, 41% of papillary type, and 53.8% of chromophobe type. Although there is not any statistical relation between the gender of patients and pathological findings, there was an obvious correlation between age and pathological findings. Before the age of 55 years, vascular sclerosis with parenchymal scarring and glomerular diseases and then chronic pyelonephritis are more prevalent.Evaluation of pathological changes in nonneo-plastic renal parenchyma is an essential step in recognizing patients at risk of accelerated functional failure of the single remaining kidney, particularly in patients with a background of chronic vascular injury associated with diabetes or hypertension

Translation of evidence into kidney transplant clinical practice: managing drug-lab interactions by a context-aware clinical decision support system

BACKGROUND: Drug-laboratory (lab) interactions (DLIs) are a common source of preventable medication errors. Clinical decision support systems (CDSSs) are promising tools to decrease such errors by improving prescription quality in terms of lab values. However, alert fatigue counteracts their impact. We aimed to develop a novel user-friendly, evidence-based, clinical context-aware CDSS to alert nephrologists about DLIs clinically important lab values in prescriptions of kidney recipients. METHODS: For the most frequently prescribed medications identified by a prospective cross-sectional study in a kidney transplant clinic, DLI-rules were extracted using main pharmacology references and clinical inputs from clinicians. A CDSS was then developed linking a computerized prescription system and lab records. The system performance was tested using data of both fictitious and real patients. The "Questionnaire for User Interface Satisfaction" was used to measure user satisfaction of the human-computer interface. RESULTS: Among 27 study medications, 17 needed adjustments regarding renal function, 15 required considerations based on hepatic function, 8 had drug-pregnancy interactions, and 13 required baselines or follow-up lab monitoring. Using IF & THEN rules and the contents of associated alert, a DLI-alerting CDSS was designed. To avoid alert fatigue, the alert appearance was considered as interruptive only when medications with serious risks were contraindicated or needed to be discontinued or adjusted. Other alerts appeared in a non-interruptive mode with visual clues on the prescription window for easy, intuitive notice. When the system was used for real 100 patients, it correctly detected 260 DLIs and displayed 249 monitoring, seven hepatic, four pregnancy, and none renal alerts. The system delivered patient-specific recommendations based on individual lab values in real-time. Clinicians were highly satisfied with the usability of the system. CONCLUSIONS: To our knowledge, this is the first study of a comprehensive DLI-CDSS for kidney transplant care. By alerting on considerations in renal and hepatic dysfunctions, maternal and fetal toxicity, or required lab monitoring, this system can potentially improve medication safety in kidney recipients. Our experience provides a strong foundation for designing specialized systems to promote individualized transplant follow-up care
