Designing a customized clinical practice guideline regarding antibiotic prophylaxis for Iranian general dentists.

BACKGROUND: Clinical practice guidelines produced by developed countries seemed to be not completely feasible for developing countries due to their different local context. In this study, we designed a customized guideline about antibiotic prophylaxis before dental procedures for Iranian general dentists. METHODS: This study was conducted of two parts, including a qualitative part and a cross-sectional analytic part. A multidisciplinary team searched for related guidelines and other documents, selected the most updated and high quality ones, customized their recommendations based on available antibiotics in Iran, prepared a draft adapted guideline and summarized its recommendations in 3 flowcharts. An expert panel (20 specialists of four Iranian dental universities) participated in a consensus process, afterwards to determine the relevance and clarity of the flowcharts and their items. Then the Content Validity Indices (CVIs) were calculated and any items with CVI higher than 0.79 remained. RESULTS: The adapted recommendations were summarized in flowcharts A to C. Two separate groups of patients who need antibiotic prophylaxis were presented in flowchart A; including those with high risk for distant-site infection (infective endocarditis and prosthetic joint infection) and those at risk for poor healing and orofacial infection (due to impaired immunologic function). Flowcharts B and C described antibiotic regimen and also the dental procedures where antibiotic prophylaxis was needed for mentioned groups. The content validity indices and the percentages of agreement between the expert panel members were considerably high. CONCLUSIONS: A localized, clear and straight forward guideline that addresses all groups of dental patients who need antibiotic prophylaxis has been produced for Iranian general dentists

Relationship between platelet parameters and sudden sensorineural hearing loss: a systematic review and meta-analysis

Background: Sudden deafness or sudden sensorineural hearing loss (SSNHO is defined as sensorineural hearing loss of greater than 30 dB over 3 contiguous puretone frequencies occurring within 3 days' periodObjective: To investigate the relationship of some platelet parameters including platelet count (PC), mean platelet volume (MPV) and platelet distribution width (PDW) with the occurrence of SSNHL.Data source: A PubMed, Science Direct, Scopus, OVID, EMBASE and Google Scholar search (date last searchedApril2016) search was done. No restrictions of time, language and location were placed.Study selection: All case-control studies which have been studied the relationship of PC, MPV and PDW with the occurrence of SSNHL were included in the meta-analysis.Data extraction: The required data from selected studies including the title, authors, publication date, location of study, sample size of patients and control groups, number of withdrawals, the mean and standard deviation of PC, MPV and PDW for patients and control groups and the result of different tests were extracted and entered to EX CELL.Data synthesis: A total of 9 case-control studies were r found in our search from them 8 studies have reported mean PC, 7 studies have reported mean MPV and 4 studies have reported mean PDW. Our analysis showed that mean PC of patients is 0.03 (-0.14-0.20) unit higher than that of controls with 95% CI which is not statistically significant. Also, mean MPV of patients is 0.31 (-0.03-0.65) unit higher than that of controls with 95% CI which is statistically not significant too. Finally, mean PDW of patients is 0.70 (0.03- 1.37) unit higher than that of controls with 95% CI which is statistically significant.Conclusions: Our study confirmed only the probable relationship of PDW and SSNHL but due to the limited studies on this subject more studies is needed

Feasibility of implementing public-private partnership (PPP) in the development of hospital services and optimizing resource allocation in Iran

Background: In recent decades, many countries have utilized public-private partnership (PPP) as a development initiative to reform their healthcare sectors. The present study examines the feasibility of implementing public-private partnerships for development of hospital services in Shiraz, Iran. Methods: This was a descriptive study of questionnaires carried out on one of Iran's major southern cities (Shiraz) in 2016. Research population comprised of the hospitals affiliated to the Shiraz University of Medical Sciences (SUMS), private hospitals, charities, and healthcare investors. A total of 56 participants were chosen by convenience sampling. Data were collected using a researcher-made questionnaire. The questions' range were defined from 1 to 5. Data analysis was performed in SPSS21 using the Mann-Whitney test, T test, and Chi square test at 0.05 significance level. Results: The participants from the public sector had a significantly higher level of acquaintance with the concept of PPP and significantly more inclination to participate in such projects (P < 0.05). The mean values of the determinants of successful implementation of PPPs for hospital services were presented from the public and private participants' viewpoints as follows: public sector rated the capacity-creating (2.60 ± 0.39) and the social-cultural (2.58 ± 0.40) component as having a better condition than other determinants however, the private sector rated the financial-capital (2.64 ± 0.46) as the best. Analysis of the mean scores of determinants of implementation of PPP from the viewpoint of public and private sectors showed a significant difference in their views in terms of financial-capital and social-cultural dimensions (P < 0.05). Conclusions: According to the participants, the requirements for implementation of public-private partnerships for hospital services are not properly met. For any progress to be made in this regard, Iranian authorities and policymakers should devise a new platform for attracting private participation and improving hospitals' readiness to engage in PPP projects. © 2020 The Author(s)

A Qualitative Study to Identify Skills and Competency Required for Hospital Managers

Introduction: Hospital managers aim to improve the efficiency and effectiveness of their institutions through leadership and guidance of medical personnel. Fulfilling these objectives requires a holistic approach to both the management of people and institutional prioritization. The aim of this study was to identify the skills and competencies that hospital managers must demonstrate in order to achieve their objectives. Methods: In 2015, a regional, multi-center qualitative study was undertaken in Shiraz, Iran. Interviews and focus group discussions were conducted with university hospital managers, senior managers, faculty members, and post-graduate students, and the results were analyzed using the content analysis method by MAXQDA software. Results: Eight key skill themes (communication, experience, appreciation of institution logistics/infrastructure, management skills, motivation, systematic problem solving, ethics, and financial/legal awareness) were identified among the hospital managers. The common challenges that face hospital institutions include problems with hierarchical and organizational structure, excessive rules and regulations, lack of resources, poor post-graduate education, and overall management. Recurring themes with respect to how these could be addressed included changing the culture and belief structure of the hospital, restructuring the organizational hierarchy, and empowering the people. Conclusion: In our cohort, practical skills, such as communication and experience, were considered more important than theoretical skills for the effective management and administration of hospitals. Therefore, we suggest that practical, skill-based training should be emphasized for students of these disciplines so they will be better suited to deal with real world challenges. Further organizational improvements also can be attained by the active and constructive involvement of senior university managers

Can public-private partnership (PPP) improve hospitals' performance indicators?

Background: This study was conducted to compare the main performance indicators of Hasheminejad hospital before and after implementing PPP model. Methods: This cross sectional study was conducted in Iran in 2015. Performance indicators of Hasheminejad hospital, the only Iranian unit that implemented PPP model, were applied. Data were collected based on a researcher-designed checklist after ensuring its validity and reliability. Data were analyzed applying SPSS21, and the Shapiro-Wilk test was used to examine the relevant data normalization. After confirming the normality of the data, descriptive statistics and paired t test were used to analyze the data at a significant level of 0.05. Results: Dramatic variations were observed in the status of the studied indicators after the implementation of PPP in Hasheminejad hospital, and the changes were statistically significant in all these indicators (p < 0.05). Conclusion: It seems that implementing PPP in Hasheminejad hospital can be considered as a successful experience in Iran's health sector. The significant improvement in this hospital's performance indicators can emphasize the effective role of PPP in administration of this hospital. However, service quality and patient satisfaction should be considered as qualitative indicators, along with the present quantitative indicators because better judgment about the changes was achieved in this hospital after implementing PPP. © Iran University of Medical Sciences

Effect of two major health reforms on health care cost and utilization in Fars Province of Iran: Family physician program and health transformation plan

Background: Family physician program (FPP) and health transformation plan (HTP) are two major reforms that have been implemented in Iran's health system in recent. The present study was aimed at evaluating the impact of these two reforms on the level of service utilization and cost of health care services. Methods: This longitudinal study was conducted on people insured by social security organization in Fars province during 2009-2016. The data on the utilization of services and costs of general practitioner visits, specialist visits, medications, imaging, laboratory tests, and hospitalization were collected. Interrupted time series analysis was used to analyze the effect of the two mentioned reforms. Results: FPP resulted in a significant reduction in the number of specialist visits, imaging, and laboratory tests in the short term, and in the number of radiology services, laboratory tests, and hospitalization in the long term. In contrast, HTP significantly increased the utilization of radiology services and laboratory tests both in the short term and long term. Concerning the costs, FPP resulted in a reduction in costs in short and long term except general practitioners' and specialist visit, and medication in long term. However, HTP resulted in an increase in health care costs in both of the studied time periods. Conclusions: FPP has been successful in rationalizing the utilization of services. On the other hand, HTP has improved people's access to services by increasing the utilization; but it has increased health care costs. Therefore, policymakers must adopt an agenda to revise and re-design the plan. © 2020 The Author(s)

TREM-1 expression on neutrophils and monocytes of septic patients: relation to the underlying infection and the implicated pathogen

<p>Abstract</p> <p>Background</p> <p>Current knowledge on the exact ligand causing expression of TREM-1 on neutrophils and monocytes is limited. The present study aimed at the role of underlying infection and of the causative pathogen in the expression of TREM-1 in sepsis.</p> <p>Methods</p> <p>Peripheral venous blood was sampled from 125 patients with sepsis and 88 with severe sepsis/septic shock. The causative pathogen was isolated in 91 patients. Patients were suffering from acute pyelonephritis, community-acquired pneumonia (CAP), intra-abdominal infections (IAIs), primary bacteremia and ventilator-associated pneumonia or hospital-acquired pneumonia (VAP/HAP). Blood monocytes and neutrophils were isolated. Flow cytometry was used to estimate the TREM-1 expression from septic patients.</p> <p>Results</p> <p>Within patients bearing intrabdominal infections, expression of TREM-1 was significantly lower on neutrophils and on monocytes at severe sepsis/shock than at sepsis. That was also the case for severe sepsis/shock developed in the field of VAP/HAP. Among patients who suffered infections by Gram-negative community-acquired pathogens or among patients who suffered polymicrobial infections, expression of TREM-1 on monocytes was significantly lower at the stage of severe sepsis/shock than at the stage of sepsis.</p> <p>Conclusions</p> <p>Decrease of the expression of TREM-1 on the membrane of monocytes and neutrophils upon transition from sepsis to severe sepsis/septic shock depends on the underlying type of infection and the causative pathogen.</p

Nonviral Approaches for Neuronal Delivery of Nucleic Acids

The delivery of therapeutic nucleic acids to neurons has the potential to treat neurological disease and spinal cord injury. While select viral vectors have shown promise as gene carriers to neurons, their potential as therapeutic agents is limited by their toxicity and immunogenicity, their broad tropism, and the cost of large-scale formulation. Nonviral vectors are an attractive alternative in that they offer improved safety profiles compared to viruses, are less expensive to produce, and can be targeted to specific neuronal subpopulations. However, most nonviral vectors suffer from significantly lower transfection efficiencies than neurotropic viruses, severely limiting their utility in neuron-targeted delivery applications. To realize the potential of nonviral delivery technology in neurons, vectors must be designed to overcome a series of extra- and intracellular barriers. In this article, we describe the challenges preventing successful nonviral delivery of nucleic acids to neurons and review strategies aimed at overcoming these challenges
