A Case of Isolated Bicuspid Pulmonic Valve and Pulmonary Artery Aneurysm
Authors: Sahebjam Mohammad , Toofaninejad Neda 
Published: January 2022

A 33-year-old woman with a history of thyroid surgery for thyroid cancer and radioactive iodine therapy was referred for echocardiography due to dyspnea on exertion.
Transthoracic echocardiography showed normal left ventricular size and function (the ejection fraction = 55%), a prolapsing mitral valve with redundant chordae, mild mitral regurgitation, a tricuspid aortic valve, mild aortic insufficiency, and mild tricuspid regurgitation. The most remarkable echocardiographic findings were moderate right ventricular dilation with mild systolic dysfunction, moderate right atrial dilation, an aneurysmal pulmonary artery (the main pulmonary artery = 47 mm), mild pulmonary stenosis (the peak gradient = 22 mmHg), and severe pulmonary regurgitation (the vena contracta = 6–7 mm and the pressure half time = 105 ms).
Transesophageal echocardiography with the use of 3D modalities demonstrated a bicuspid pulmonic valve with doming and poor coaptation of the pulmonic valve leaflets (Figure 1). Additionally, a large patent foramen ovale was visualized in color Doppler (the flap separation = 2 mm and the tunnel length = 11 mm) with bubble passage in agitated saline injection.
Bicuspid pulmonic valves constitute a rare finding, and they are most often associated with other congenital heart diseases. Isolated bicuspid pulmonic valves are extremely rare, with an incidence rate of about 0.1% in clinical practice.1 Pulmonary artery aneurysms also comprise a rare abnormality, with an incidence rate of approximately 1 in 14 000 cases in most studies.2 The association between bicuspid pulmonic valves and pulmonary artery aneurysms has been reported, and the pathophysiologic causes of this association include hemodynamic alterations due to bicuspid pulmonic valves and most likely the abnormal migration of neural crest cells.3
The diagnosis of a bicuspid pulmonic valve by 2D imaging is challenging and sometimes impossible. Using 3D echocardiography and reconstruction confers a better assessment of the pulmonic valve morphology and identification of bicuspid pulmonic valves.

Introduction: Back pain is one of the most important occupational problems among health care workers that have detrimental effects on their personal and professional life. Therefore, this study aimed to investigate the relationship between low back pain and quality of life in prehospital emergency staff and the role of demographic variables in this regard.
Materials and Methods: This is a descriptive correlational study. The population was a prehospital emergency staff that entered to study by using the census method at 2020. Data gathering instruments were demographic characteristics, low back pain, and quality of life questionnaires. Data were entered into SPSS 22 and were analyzed using descriptive and analytical statistics.
Results: The results showed that the related to the low back pain score of emergency medical technicians was 51.34± 4.149, which is high. In addition, the quality of life mean and standard deviation was 30.35± 4.851, which shows a low level. There is a significant relationship between back pain and quality of life (p = 0.001, R = 0.723).
Conclusion: Low back pain is so common among emergency medical personnel that the issue may affect a person's life and work and creates many problems in terms of personal, family, socially, economically, and professionally, which reduce their quality of life.

Published: January 2022

Introduction: A firefighting job is a demanding job that has a high degree of stress due to constant exposure to life-threatening conditions. Therefore, the present study investigates the mediating role of intrinsic job motivation in the relationship between job commitment and professional ethics with extra-role performance among firefighters in Isfahan.
Materials and Methods: The type of study was descriptive and correlational. The statistical population included all firefighters in Isfahan, from which 228 people were selected as a sample through random sampling. The instruments used include internal job motivation questionnaires (Gagne et al., 2015), job commitment (Blau, 2009), professional ethics (Hackerina, 2011), and extra-role performance (Lee and Allen, 2002). Data were analyzed by the Pearson correlation coefficient and structural equation modeling (SEM). SPSS23 and Smart PLS3 software were used for data analysis.
Results: The results showed that professional ethics has a direct effect on intrinsic job motivation, extra-role performance toward organization and individual; Intrinsic job motivation affects directly on the extra-role performance toward an individual; Job commitment has a direct effect on intrinsic job motivation and extra-role performance toward the organization (P <0.05). Also, the proposed model has a good fit and by examining the indirect and mediating effects through the bootstrapping method in PLS software, was shown that intrinsic job motivation mediates the effect of job commitment and professional ethics on the extra- role performance toward the individual.
Conclusion: The findings of the present study showed that professional ethics and job commitment could increase extra-role behaviors through intrinsic job motivation. Therefore, due to the role and importance of extra-role behaviors in the firefighting profession, attention to this should be considered by managers and policymakers of this organization.

Published: January 2022

Introduction: Nowadays, the cement industry is regarded as one of the most important air pollution industries globally. This study aimed to simulate the emission of NOx, CO, SO2, and PM pollutants caused by the Sabzevar Cement Factory chimney by SCREEN3 software.
Materials and Methods: In this study, the SCREEN3 software was employed for the distribution of NOx, CO, SO2, and PM pollutants. The inputs of the model include the concentration and emission of pollutant gases, physical factors associated with the cement factory chimney, wind speed and direction, ambient temperature, and stability classes.
Results: The results of this study indicated that the maximum concentrations of NOx, CO, SO2, and PM by the SCREEN3 software occurred in unstable weather conditions (B) and wind speed of 5 m.s. The highest concentrations of NOx, CO, and PM (use of gas) were at a distance of 1400 meters from the factory chimney with the rates of 0.9, 0.32, 6.2 μg.m³, respectively. Moreover, the highest concentrations of NOx, CO, SO2, and PM (using fuel oil) were predicted at a distance of 1100 m from the factory chimney with 19.5, 360, 9, and 7.9 μg.m³, respectively. A comparison of the obtained results with the standard of the Environmental Protection Agency of Iran (EPA) revealed that the concentrations of NOx, CO, SO2, and PM were not higher than the standards.
Conclusion: The comparison of results with EPA standard and Iranian clean air standard showed that NOX, CO, SO2, and PM concentrations were not higher than standards during the sampling period.

Published: January 2022

Introduction: Lead is a toxic heavy metal that has adverse health effects on blood parameters. About 80% of lead produced is used in batteries, especially vehicle batteries. Therefore, the present study aimed to assess the hematological changes, including total and differential white blood cell (WBC) counts in battery workers exposed to lead, and compare with the non-exposed group.
Materials and Methods: This cross-sectional study was carried out in a battery industry in Semnan city. The study population consisted of 78 battery workers and 78 healthy non-exposed office workers. A hematology cell counter was used to determine the total, and differential WBC counts. Blood lead level was measured in accordance with the NIOSH method 8003.
Results: Blood lead levels were about two times higher than the TLV recommended by the American Conference of Governmental Industrial Hygienists (ACGIH) for this compound (20 µg/dl). The level of WBC (8.07± 2.55 mm3 blood×103 vs. 7.27 ± 1.58 mm3 blood×103) was significantly higher, while the level of monocyte was significantly lower (6.96 ± 1.72 % vs. 7.67 ± 1.87 %) in the exposed group than in the non-exposed group. After adjustment for potential confounders such as age and work history, a significant association between exposure to lead and WBC and monocyte levels was reported.
Conclusion: The present study's findings indicated that exposure to lead was associated with total and differential white blood cells changes in the exposed group compared to the non-exposed group.

Published: January 2022

Introduction: A high-risk job, firefighting involves a wide range of tasks. Given the difficult nature of the job with all the responsibilities included, and in addition to the impending physical injuries, firefighters undergo several emergencies which can endanger their psychological health. Therefore, the present study was conducted to investigate the psychological consequences of firefighters' work conditions.
Materials and Methods: The research method was qualitative and phenomenological. Using the purposeful sampling method, 16 firefighters were selected from fire stations across the city of Kerman, Iran; saturation criteria were used in the selection of participants. Data were collected using semi-structured interviews and analyzed using Colaizzi’s seven-step method. In this way, first, the interviews were coded, and then based on the similarity of codes, 4 main categories were extracted.
Results: results showed that persistent stress (caused by the sound of fire alarms and announcement of fire emergencies, trying to make it to the scene on time, worrying about not being on time, and not finding the address of the incidents, complications, and uncertainties of the incidents), sleep problems (these include sleep disturbances, insomnia, difficulty maintaining sleep, startled waking up, somniloquy), negative emotions reminiscent of painful events, and difficulty in establishing good relationships with family members, are the most important psychological consequences that firefighters faced due to their working conditions.
Conclusion: Considering the important role of firefighters in providing services in emergencies, the psychological consequences of this job are risk factors that harm the health and the performance of firefighters. Therefore, appropriate measures and planning need to be taken to manage and reduce ongoing stress and improve the quality of firefighters' sleep. To manage and reduce negative emotions and their family problems, appropriate training should be provided.

Authors: Dasyapu Adyathan , Nagubilli Greeshmika , Kutcharlapati Jayanth V , Guntuku Hari Prasad , Nagdeve Shruti S 
Published: January 2022

Purpose: Engineering, procurement, and construction (EPC) contracts are on their way to becoming the most common type of contract used by the private sector for large-scale infrastructure projects. Every project requires a strong relationship between all of the experts participating in EPC projects and the client. This relationship must be solidly established by an architect; otherwise, the project may fail for all parties involved, including the client, contractor, lenders, government, and others. The purpose of this study is to identify if the working of the EPC contracts is favourable for the architectural profession, and to identify the way in which the working could be improved.
Methodology: A qualitative approach was applied to analyze the critical points of EPC contracts based upon reviews of related case studies from the public sector and supplementary interviews with professionals in the field.
Main Finding: The architect's role in an EPC contract is not crucial and is equal to other stakeholders involved in the project. Also, EPC contractors have the power to dictate the workflow of the project and hence, architects might have to compromise in terms of the design, compensation, etc.
Implications: It is very important for every project to have an outcome based on each stakeholders/consultants inputs specially on larger projects, this article is a step towards understanding the role of architects under an EPC contract as the future projects will come under its purview.
Novelty: The study is done under the lens of a newly graduated architect and not as any other professional, thereby trying to develop an understanding for fresh architects.

Authors: Iskandar Azwar , Bayu Taufiq Possumah  , Khaerul Aqbar  , Akhmad Hanafi Dain Yunta  
Published: January 2022

The recent studies about the role of Islamic philanthropy in addressing socio-economic problems have been growing and confirming its significant role in overcoming the problem. This is in line with the existence of regulations that support the effectiveness of its role in poverty reduction in Indonesia, such as Law No. 23 of 2011 on Zakat Management and Law No. 41 of 2004 on Waqf. This study has two objectives. First, to analyze the impact of Islamic philanthropy on poverty reduction as the socio-economic problems in Indonesia in the short and long run. Second, to analyze the effectiveness of integrated Islamic commercial and social-economic or finance to address the poverty compared to unintegrated one. This study used Auto-Regressive Distributed Lag (ARDL) approach to analyze annual data for the period of 2002-2019 while investigating the long and short-run relationships among variables. It found that Islamic philanthropy reduces poverty both in the short and long run, particularly in the integration of Islamic social and commercial finance in a single model. The government should therefore include Islamic philanthropy or other Islamic social finances as a fundamental strategy for building financial stability and sustainable development. (Menjamurnya studi-studi terbaru terkait peran filantropi Islam dalam mengatasi masalah sosial-ekonomi telah mengkonfirmasi peran pentingnya dalam mengatasi masalah ini. Hal ini sejalan dengan adanya regulasi yang mendukung efektivitas perannya dalam pengentasan kemiskinan di Indonesia, seperti Undang-Undang Nomor 23 Tahun 2011 tentang Pengelolaan Zakat dan Undang-Undang Nomor 41 Tahun 2004 tentang Wakaf. Penelitian ini memiliki dua tujuan. Pertama, untuk menganalisis dampak filantropi Islam terhadap penurunan tingkat kemiskinan sebagai sebuah permasalahan sosial-ekonomi di Indonesia, baik dalam jangka pendek maupun jangka panjang. Kedua, untuk menganalisis efektifitas integrasi atau antara filantropi dan komersial dalam kerangka ekonomi Islam dalam mengatasi permasalahan kemiskinan. Penelitian ini menggunakan pendekatan Auto-Regressive Distributed Lag (ARDL) untuk menginvestigasi hubungan jangka pendek dan jangka panjang antara filantropi Islam dan tingkat kemiskinan selama periode tahun 2002-2019. Penelitian ini menemukan bahwa filantropi Islam dapat menurunkan tingkat kemiskinan baik dalam jangka pendek maupun jangka panjang. Penelitian ini juga menemukan bahwa ketika filantropi dan komersial dalam kerangka ekonomi Islam diintegrasikan, tingkat kemiskinan dapat diturunkan baik dalam jangka pendek maupun jangka panjang. Pemerintah seyogiyanya menempatkan filantropi Islam sebagai kebijakan dan strategi fundamental dalam rangka mewujudkan stabilitas keuangan dan pembangunan berkelanjutan.)

O objetivo desta pesquisa foi ‘Relacionar a formação e prerrogativas de atuação profissional do Administrador com a atividade de avaliação prevista na NBR 14.653-4 – Avaliação de empreendimentos’. A pesquisa possui abordagens qualitativa e quantitativa, cuja coleta de dados foi realizada por meio de entrevistas pessoais junto a especialistas e pesquisa documental, tendo os projetos pedagógicos de 59 cursos de Administração e Engenharia (Civil e Produção) como objeto de pesquisa. Os resultados mais relevantes indicam que há convergência quanto a opinião dos especialistas ao reconhecer que o Administrador está apto a realizar a avaliação de empreendimentos e que sua formação acadêmica, em media possui maior aderência aos requisitos da norma NBR 14.653-4, que de Engenheiros (Civil e de Produção). Entretanto, normas infraconstitucionais de regulamentação profissional definem o grupo de profissionais registrados no CREA (engenheiros, agrônomos, geólogos, geógrafos e dos meteorologistas) como aquele apto a realizar a atividade de avaliação de empreendimentos com base na NBR 14.653-4. Os resultados devem ser tratados como um indicativo sobre a regulação profissional relacionada à avaliação de empreendimentos no Brasil pois, em função das características da pesquisa não podem ser generalizados.
Deriving Weight From Big Data: Comparison of Body Weight Measurement–Cleaning Algorithms
Authors: Evans Richard , Burns Jennifer , Damschroder Laura , Annis Ann , Freitag Michelle B , Raffa Susan , Wiitala Wyndy 
Published: January 2022

Background
Patient body weight is a frequently used measure in biomedical studies, yet there are no standard methods for processing and cleaning weight data. Conflicting documentation on constructing body weight measurements presents challenges for research and program evaluation.

Objective
In this study, we aim to describe and compare methods for extracting and cleaning weight data from electronic health record databases to develop guidelines for standardized approaches that promote reproducibility.

Methods
We conducted a systematic review of studies published from 2008 to 2018 that used Veterans Health Administration electronic health record weight data and documented the algorithms for constructing patient weight. We applied these algorithms to a cohort of veterans with at least one primary care visit in 2016. The resulting weight measures were compared at the patient and site levels.

Results
We identified 496 studies and included 62 (12.5%) that used weight as an outcome. Approximately 48% (27/62) included a replicable algorithm. Algorithms varied from cutoffs of implausible weights to complex models using measures within patients over time. We found differences in the number of weight values after applying the algorithms (71,961/1,175,995, 6.12% to 1,175,177/1,175,995, 99.93% of raw data) but little difference in average weights across methods (93.3, SD 21.0 kg to 94.8, SD 21.8 kg). The percentage of patients with at least 5% weight loss over 1 year ranged from 9.37% (4933/52,642) to 13.99% (3355/23,987).

Conclusions
Contrasting algorithms provide similar results and, in some cases, the results are not different from using raw, unprocessed data despite algorithm complexity. Studies using point estimates of weight may benefit from a simple cleaning rule based on cutoffs of implausible values; however, research questions involving weight trajectories and other, more complex scenarios may benefit from a more nuanced algorithm that considers all available weight data.
Incidence of Diagnostic Errors Among Unexpectedly Hospitalized Patients Using an Automated Medical History–Taking System With a Differential Diagnosis Generator: Retrospective Observational Study
Authors: Kawamura Ren , Harada Yukinori , Sugimoto Shu , Nagase Yuichiro , Katsukura Shinichi , Shimizu Taro 
Published: January 2022

Background
Automated medical history–taking systems that generate differential diagnosis lists have been suggested to contribute to improved diagnostic accuracy. However, the effect of these systems on diagnostic errors in clinical practice remains unknown.

Objective
This study aimed to assess the incidence of diagnostic errors in an outpatient department, where an artificial intelligence (AI)–driven automated medical history–taking system that generates differential diagnosis lists was implemented in clinical practice.

Methods
We conducted a retrospective observational study using data from a community hospital in Japan. We included patients aged 20 years and older who used an AI-driven, automated medical history–taking system that generates differential diagnosis lists in the outpatient department of internal medicine for whom the index visit was between July 1, 2019, and June 30, 2020, followed by unplanned hospitalization within 14 days. The primary endpoint was the incidence of diagnostic errors, which were detected using the Revised Safer Dx Instrument by at least two independent reviewers. To evaluate the effect of differential diagnosis lists from the AI system on the incidence of diagnostic errors, we compared the incidence of these errors between a group where the AI system generated the final diagnosis in the differential diagnosis list and a group where the AI system did not generate the final diagnosis in the list; the Fisher exact test was used for comparison between these groups. For cases with confirmed diagnostic errors, further review was conducted to identify the contributing factors of these errors via discussion among three reviewers, using the Safer Dx Process Breakdown Supplement as a reference.

Results
A total of 146 patients were analyzed. A final diagnosis was confirmed for 138 patients and was observed in the differential diagnosis list from the AI system for 69 patients. Diagnostic errors occurred in 16 out of 146 patients (11.0%, 95% CI 6.4%-17.2%). Although statistically insignificant, the incidence of diagnostic errors was lower in cases where the final diagnosis was included in the differential diagnosis list from the AI system than in cases where the final diagnosis was not included in the list (7.2% vs 15.9%, P=.18).

Conclusions
The incidence of diagnostic errors among patients in the outpatient department of internal medicine who used an automated medical history–taking system that generates differential diagnosis lists seemed to be lower than the previously reported incidence of diagnostic errors. This result suggests that the implementation of an automated medical history–taking system that generates differential diagnosis lists could be beneficial for diagnostic safety in the outpatient department of internal medicine.
