Assessment Development

Assessing occupational exposure in retrospective community-based case-control studies is difficult as measured exposure data are very seldom available. The expert assessment method is considered the most accurate way to attribute exposure but it is a time consuming and expensive process and may be seen as subjective, nonreproducible, and nontransparent. In this paper, we describe these problems and outline our solutions as operationalized in a web-based software application (OccIDEAS). The novel aspects of OccIDEAS are combining all steps in the assessment into one software package; enmeshing the process of assessment into the development of questionnaires; selecting the exposure(s) of interest; specifying rules for exposure assignment; allowing manual or automatic assessments; ensuring that circumstances in which exposure is possible for an individual are highlighted for review; providing reports to ensure consistency of assessment. Development of this application has the potential to make high-quality occupational assessment more efficient and accessible for epidemiological studies.

ObjectiveHealthcare workers are highly exposed to various types of disinfectants and cleaning products. Assessment of exposure to these products remains a challenge. We aimed to investigate the feasibility of a method, based on a smartphone application and bar codes, to improve occupational exposure assessment among hospital/cleaning workers in epidemiological studies.MethodsA database of disinfectants and cleaning products used in French hospitals, including their names, bar codes and composition, was developed using several sources: ProdHyBase (a database of disinfectants managed by hospital hygiene experts), and specific regulatory agencies and industrial websites. A smartphone application has been created to scan bar codes of products and fill a short questionnaire. The application was tested in a French hospital. The ease of use and the ability to record information through this new approach were estimated.ResultsThe method was tested in a French hospital (7 units, 14 participants). Through the application, 126 records (one record referred to one product entered by one participant/unit) were registered, majority of which were liquids (55.5%) or sprays (23.8%); 20.6% were used to clean surfaces and 15.9% to clean toilets. Workers used mostly products with alcohol and quaternary ammonium compounds (>90% with weekly use), followed by hypochlorite bleach and hydrogen peroxide (28.6%). For most records, information was available on the name (93.7%) and bar code (77.0%). Information on product compounds was available for all products and recorded in the database.ConclusionThis innovative and easy-to-use method could help to improve the assessment of occupational exposure to disinfectants/cleaning products in epidemiological studies.

BACKGROUND: Specific inhalation challenges (SIC) enable the identification of the agent responsible of occupational asthma (OA). A clinician may fail to identify a specific agent in the workplace, which may potentially lead to a misdiagnosis. The expert assessment method performed by an occupational hygienist has been used to evaluate occupational exposures in epidemiological studies.OBJECTIVE: The broad aim of the present study was to evaluate the contribution of an expert assessment performed by an occupational hygienist to the diagnosis of OA. The specific aim was to compare work-place exposures identified by an occupational hygienist and by chest physicians in subjects with positive SICs and subjects with asthma, but with a negative SIC.METHODS: SICs were performed in 120 cases: 67 were positive and 53 were negative. A clinician assessed occupational exposures to sensitizers during a routine clinical evaluation preceding the performance of the SIC. An expert assessment of occupational exposures was performed by an occupational hygienist blind to the result of the SIC.RESULTS: The occupational hygienist identified the causal agent in 96.7% of the 61 cases of positive SIC. In 33 (62.3%) cases of negative SICs, the occupational hygienist identified ≥1 sensitizing agent(s) that had not been identified by the clinician.CONCLUSION: The hygienist identified the causal agent in almost all subjects with OA. In contrast, the clinician failed to identify potential exposures to sensitizers in >60% of the negative SIC subjects, which may have resulted in some subjects being misdiagnosed as not having OA.

With the mounting demand of web applications, a number of issues allied to its quality have came in existence. In the meadow of web applications, it is very thorny to develop high quality web applications. A design pattern is a general repeatable solution to a generally stirring problem in software design. It should be noted that design pattern is not a finished product that can be directly transformed into source code. Rather design pattern is a depiction or template that describes how to find solution of a problem that can be used in many different situations. Past research has shown that design patterns greatly improved the execution speed of a software application. Design pattern are classified as creational design patterns, structural design pattern, behavioral design pattern, etc. MVC design pattern is very productive for architecting interactive software systems and web applications. This design pattern is partition-independent, because it is expressed in terms of an interactive application running in a single address space. We will design and analyze an algorithm by using MVC approach to improve the performance of web based application. The objective of our study will be to reduce one of the major object oriented features i.e. coupling between model and view segments of web based application. The implementation for the same will be done in by using .NET framework.

BACKGROUND Lung transplantation recipients (LTx) are more susceptible to severe acute respiratory syndrome-corona virus-2 (SARS-Cov-2) and suffer severer outcomes than healthy subjects. OBJECTIVE Here we aim to analyze whether it was appropriate to maintain lung transplant programs in medical institutions accepting coronavirus disease 2019 (COVID-19) patients. METHODS Methods: the clinical characteristics, laboratory testing, and epidemiology survey results of 10 LTx recipients undergoing allograft lung transplantation surgeries in the First Affiliated Hospital of Zhengzhou University during the COVID-19 pandemic were collected. A web-based epidemiology questionnaire was used to collect the information of LTx recipients after discharge. RESULTS A total of 10 LTx recipients were identified. The main cause of lung transplantation was idiopathic interstitial pneumonia (60%), with another rare case of cystic fibrosis. Comorbidities involved hyperlipidemia, subclinical hyperthyroidism, diabetes, viral hepatitis of type B. The average white blood cell (WBC) count and average lymphocyte count were 9.5±3.9×109 cells/liter and 1.7±1.1×109 cells/liter, respectively. 40% of the LTx recipients had lymphopenia. Impaired alanine aminotransferase (ALT) and aspartate transaminase (AST) were observed in LTx recipients. Good habitats of hand hygiene (100%), wearing protective masks behaviors (100%), indoor ventilation behaviors (100%), indoor disinfection measures (83%), personal tableware (67%), separate room (100%), personal bedsheets/ quilts (100%) and drinking glasses (100%) were observed during the follow-up. None of the LTx recipients or their family members get infected with SARS-CoV-2 during the novel coronavirus pandemic. CONCLUSIONS Under the premise of taking appropriate preventive measures during hospitalization and after discharge, the lung transplant program can be maintained in the medical institution that accepts patients with COVID-19.

It is expected that the results of this study can be an important research that produces effective and efficient software to evaluate the lecturers' performance nationally because it involves a 360degree assessment. We have done some activities to develop the prototype software application of Integrated Evaluation Model (IEM) for assessing the certified lecturer's performance. They are 1) preparing the questionnaire indicator for the 360 degree performance appraisal, 2) conduct the program test on the certified lecturer. In this phase, certified lecturers, superior, and students also conduct assessment on certified lecturers through IEM software, 3) conduct Focus Group Discussion (FGD) to gain evaluation and feedback on the effectiveness of the IEM application program. FGD results provide a valuable contribution to the preparation of IEM program design. And the IEM software produced in this research has accommodated all of the results of FGD activities. IEM complements the prior certified lecturer performance appraisal with 360 degrees performance appraisal.
