Development and application of a social accountability assessment tool at the Shahid Beheshti University of Medical Sciences

Background: One of the critical needs of governmental agencies and educational institutions is meeting community needs. Organizations and governmental systems that rely on social capital are considered inefficient and vulnerable if they are unable to meet the needs of society. Thus, accountability is a critical pillar of government management that leads to effective actions and better service delivery. Methods: Critical review methodology was used in the first phase to review texts and documents available in the field of social accountability and to collect items used to develop the social accountability assessment tool. The Delphi method was then used to finalize and approve the model and assessment tool. University processes were investigated and evaluated based on the social accountability tool in the second phase. Result: In all, 422 university processes were investigated and evaluated to determine their accountability in different fields. The mean score of the evaluated processes was 11.9 out of 100. Conclusion: The results show that social accountability is a relatively new topic that has received considerable attention in medical education in Iran. Given the relative newness of this topic, these results could be expected; social accountability should try and be expected to improve in the coming years

Two-dimensional graphitic carbon nitride (g-C3N4) nanosheets and their derivatives for diagnosis and detection applications

The early diagnosis of certain fatal diseases is vital for preventing severe consequences and contributes to a more effective treatment. Despite numerous conventional methods to realize this goal, employing nanobiosensors is a novel approach that provides a fast and precise detection. Recently, nanomaterials have been widely applied as biosensors with distinctive features. Graphite phase carbon nitride (g-C3N4) is a two-dimensional (2D) carbon-based nanostructure that has received attention in biosensing. Biocompatibility, biodegradability, semiconductivity, high photoluminescence yield, low-cost synthesis, easy production process, antimicrobial activity, and high stability are prominent properties that have rendered g-C3N4 a promising candidate to be used in electrochemical, optical, and other kinds of biosensors. This review presents the g-C3N4 unique features, synthesis methods, and g-C3N4-based nanomaterials. In addition, recent relevant studies on using g-C3N4 in biosensors in regard to improving treatment pathways are reviewed

Global systematic review of primary immunodeficiency registries

Introduction During the last 4 decades, registration of patients with primary immunodeficiencies (PID) has played an essential role in different aspects of these diseases worldwide including epidemiological indexes, policymaking, quality controls of care/life, facilitation of genetic studies and clinical trials as well as improving our understanding about the natural history of the disease and the immune system function. However, due to the limitation of sustainable resources supporting these registries, inconsistency in diagnostic criteria and lack of molecular diagnosis as well as difficulties in the documentation and designing any universal platform, the global perspective of these diseases remains unclear. Areas covered Published and unpublished studies from January 1981 to June 2020 were systematically reviewed on PubMed, Web of Science and Scopus. Additionally, the reference list of all studies was hand-searched for additional studies. This effort identified a total of 104614 registered patients and suggests identification of at least 10590 additional PID patients, mainly from countries located in Asia and Africa. Molecular defects in genes known to cause PID were identified and reported in 13852 (13.2% of all registered) patients. Expert opinion Although these data suggest some progress in the identification and documentation of PID patients worldwide, achieving the basic requirement for the global PID burden estimation and registration of undiagnosed patients will require more reinforcement of the progress, involving both improved diagnostic facilities and neonatal screening.Peer reviewe

Diagnostic Performance of Ultrasonography for Identification of Small Bowel Obstruction: A Systematic Review and Meta-analysis

Introduction: Small bowel obstruction (SBO) is known as a common cause of acute abdominal complaints in the emergency department (ED). The modality of choice for the diagnosis of SBO has not yet been established. This systematic review and meta-analysis aimed to investigate the accuracy of ultrasonography for the diagnosis of SBO. Methods: Systematic search was performed on five electronic databases including Medline, Scopus, Web of Sciences, Embase, and Cochrane Library, and the retrieval period was from the inception of each database to November 2023. The quality of the included studies were investigated using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). The pooled values of diagnostic characteristics for ultrasonography were estimated using meta-Disc and Stata statistical software. Results: Twenty-one studies with a total of 1977 patients were included in the meta-analysis. The pooled estimate for sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the summary ROC curve of ultrasonography for diagnosing SBO were 0.93 (95% CI: 0.91–0.95), 0.8 (95% CI: 0.77–0.83), 5.69 (95% CI: 3.64–8.89), 0.1 (95% CI: 0.07–0.16), 83.51 (95% CI: 18.12–182.91) and 0.96, respectively. Conclusion: The findings of this meta-analysis showed that the utilization of ultrasonography holds promise as a diagnostic imaging for SBO with high accuracy. However, additional worldwide studies are essential to get more evidence on the value of ultrasonography for the diagnosis of SBO

Scopes and Limits of Innovations for Sustainability in Developing Economies: A Case of Steel Industry in Iran

Sustainable development, as an increasingly important topic, ensures that development meets needs of the present while being considerate of the ability of future generations to meet their own needs. There are several concerns and issues that need to be dealt with when it comes to a sustainable development, and the concept of innovation for sustainability is therefore becoming a crucial element in addressing today’s challenges toward such a development. Innovation for sustainability is any attempt to develop something new, which improves performance with respect to environmental, economic and social pillars of sustainable development. In this regard, innovation is prerequisite to sustainability not only for the developed world but also for developing countries. This study elaborates on scopes and limits of innovation for sustainability in emerging economies as a case study in Iranian steel industry. Iran is a developing country, with rich natural resources, and a complicated economy with its specific potentials as well as problems such as the imposed sanctions, hence requiring innovativeness and novelty toward a sustainable development. From the theoretical point of view, this study elaborates on fundamentals and obstacles of innovation and ecoinnovation, sustainability in general and in the developing world, steel industry and Iranian steel industry in particular. From the empirical perspective, the study tests five hypotheses – inspired from the theoretical part of the study as well as Iran’s economic situation – based on interviews with six managers in Iran’s steel industry. The findings indicate that currently the triple pillars of sustainability in the Iranian steel industry are not considered as a holistic approach and are not mutually reinforcing. The already implemented innovations for sustainability in the Iranian steel industry have been technological innovations and mostly in state-run factories because they receive more support from the government. Organizational modifications and government’s strategic planning are required to further smooth the movement of the Iranian steel industry in the first place and Iran’s economy towards sustainability at a larger scale

Effectiveness of placement of second miniplates as tension band unit in mandibular parasymphysis fractures

Background: The ideal position of the plates and the need for additional plates are discussed continuously. In mandible, the tensile forces at the fracture line should be neutralized with a tension band. This study evaluated the role of the mandibular arch bar as a tension band eliminating the need for an upper miniplate (tension band plate) in cases of parasymphysis fractures. Materials and Methods: In this randomized control trial, a total of 90 patients with mandibular parasymphysis fractures underwent treatment in two groups. Group A was treated with one titanium miniplate along with Erich's arch bar. In Group B, two titanium miniplates were placed across the fracture site along with Erich's arch bar. Then, the complications and duration of the operation time were compared between two groups. The results were considered statistically significant when the P < 0.05. Results: No significant difference was observed between the groups regarding postoperative complication rate. 1 month after surgery in Group A, number of patients with sensory impairment (17%) was significantly lower than Group B (37%) (P = 0.029). Furthermore, the operation time of Group A was significantly shorter than Group B (P < 0.001). Conclusion: In the presence of arch bar, placing one miniplate instead of the routine technique of placing two, do not increase complication rates. Furthermore, it reduces the operation time and costs and results in a better neurosensory recovery outcome in short time

Selecting an Appropriate Configuration in a Construction Project Using a Hybrid Multiple Attribute Decision Making and Failure Analysis Methods

To successfully complete a project, selecting the most appropriate construction method and configuration is critical. There are, however, plenty of challenges associated with these complex decision-making processes. Clients require projects with the desired cost, time, and quality, so contractors should trade-off project goals through project configuration. To address this problem, in this study, an integrated FTA-DFMEA approach is proposed that implements the integrated AHP-TOPSIS method to improve construction project configuration. The proposed approach applies quality management techniques and MADM methods concurrently for the first time to improve construction project configuration considering project risks, costs and quality. At first, the Client’s requirements and market feedback are considered to identify potential failures in fulfilling project goals, and an integrated AHP-TOPSIS is used to select the most critical potential failure. Then fault tree analysis is used to indicate minimal paths. An inverse search in the operational model is performed to determine relevant tasks and identify defective project tasks based on WBS. Afterward, failure modes and effect analysis are applied to identify failure modes, and an integrated AHP-TOPSIS is used to rank failure modes and select the most critical one. Then Corrective actions are carried out for failure modes based on their priority, and project configuration is improved. This study considers construction resource suppliers with different policies, delivery lead times, warranty costs, and purchasing costs. Moreover, redundancy allocation and different configuration systems such as series and parallel are taken into account based on the arrangement and precedence of tasks. Finally, a case study of a building construction project is presented to test the viability of the proposed approach. The results indicate that the proposed approach is applicable as a time-efficient and powerful tool in the improvement of construction project configuration, which provides the optimal output by considering various criteria with respect to the client’s requirements and contractor’s obligations. Moreover, the algorithm provides various options for the contractor to improve the implementation of construction projects and better respond to challenges when fulfilling project goals
