Contexte : La Loi sur les agents pathogènes humains et les toxines et le Règlement sur les agents pathogènes humains et les toxines exigent que les incidents de laboratoire soient signalés au système de surveillance de déclaration des incidents en laboratoire au Canada de l’Agence de la santé publique du Canada. L’objectif du présent rapport est de décrire les incidents de laboratoire concernant des expositions survenues au Canada en 2020 et les personnes affectées par ces incidents. Méthodes : Les incidents survenus en laboratoire en 2020 dans des laboratoires canadiens autorisés ont été analysés. Le taux d’incidents d’exposition a été calculé et des statistiques descriptives ont été effectuées. Les incidents d’exposition ont été analysés selon le secteur, type d’activité, type d’événement, cause fondamentale et agent pathogène ou toxine. Les personnes affectées ont été analysées selon l’éducation, la voie d’exposition, le secteur, le rôle et l’expérience en laboratoire. Le temps écoulé entre l’incident et la date du rapport a également été analysé. Résultats : Quarante-deux incidents touchant 57 personnes ont été signalés au système de surveillance de déclaration des incidents en laboratoire au Canada en 2020. Aucune infection contractée en laboratoire n’a été soupçonnée ou confirmée. Le taux d’exposition annuel était de 4,2 incidents pour 100 permis en vigueur. La plupart des cas d’exposition sont survenus pendant les activités de microbiologie (n = 22, 52,4 %) ou ont été signalés par le secteur hospitalier (n = 19, 45,2 %). L’erreur de procédure (n = 16, 27,1 %) et les incidents liés à un objet tranchant ou pointu (n = 13, 22,0 %) étaient les incidents les plus fréquemment signalés. La plupart des personnes touchées ont été exposées par inhalation (n = 28, 49,1 %). Ils travaillaient à titre de techniciens ou de technologues (n = 36, 63,2 %). Les problèmes liés aux procédures opératoires normalisées étaient la cause fondamentale la plus courante (n = 24, 27,0 %), suivie des interactions humaines (n = 21, 23,6 %). Le nombre médian de jours entre les cas d’exposition et la date de déclaration était de six jours. Conclusion : Le taux d’incidents en laboratoire était plus faible en 2020 qu’en 2019, quoique la pandémie en cours ait pu contribuer à cette diminution en raison de la fermeture de lieux de travail non essentiels, notamment des laboratoires, pendant une partie de l’année. Le type d’incident le plus fréquent était l’erreur de procédure, tandis que les problèmes liés au non-respect des procédures opératoires normalisées et les interactions humaines étaient les causes fondamentales les plus citées.

Dans le contexte de la crise sanitaire Covid, le besoin massif en personnel soignant dans les établissements de santé a mis en avant les difficultés de recrutement et de fidélisation organisationnelle. Cet article présente les résultats d’une étude qualitative exploratoire menée auprès de techniciens de laboratoire, ainsi que le rôle joué par le manager de proximité lors de la mise en place d’une plateforme de dépistage de masse du coronavirus SARS-CoV-2. Les analyses de documents et du contenu de dix-huit entretiens semi-directifs ont permis d’établir le lien entre une identification organisationnelle forte et l’investissement au sein de l’organisation incarné par le souhait de rester, soit : la fidélisation organisationnelle. Ces deux concepts inter reliés sont profondément assujettis à la notion de sens au travail. En effet, au regard de ces résultats empiriques, le Sensegiving et le Sensemaking semblent caractériser les différents rôles tenus par le manager de proximité.

L'utilisation des ordinateurs par les chercheurs en sciences humaines et sociales offre des possibilités énormes. L'un des domaines dans lesquels l'application de l'informatique se révèle la plus prometteuse est l'étude socio-démographique et généalogique de communautés humaines. Lorsque la population est nombreuse et le recul historique suffisamment lointain, la quantité d'informations à manipuler est telle qu'il est impensable de pouvoir analyser les données à la main et que l'appel au concours de l'informatique devient indispensable. Dans un article récent, la méthode générale et les premiers résultats obtenus à propos de la paroisse de Bois-Vert ont été décrits. Les auteurs insistaient déjà sur la nécessité d'entrer en machine des informations aussi exemptes d'erreur que possible. C'est ainsi que les opérations de numérotation des individus et de la codification des lieux se font en laboratoire. Après vérification sur carte IBM, un triple contrôle manuel est effectué. Un programme spécial de vérification a été mis au point au Centre de calcul de l'Université de Montréal permettant de dépister des erreurs (absence d'information) ou des incompatibilités qui auraient pu échapper à la vérification manuelle (programme P0PI). L'ensemble de ces opérations est d'une durée variable suivant les caractéristiques des communautés, notamment leur effectif et la profondeur historique ; elles durent toujours plusieurs mois et occupent plusieurs techniciens. Le but du présent texte est d'insister sur une difficulté particulière rencontrée à propos d'une communauté, difficulté à laquelle on se heurte souvent dans les travaux généalogiques : le nombre restreint de patronymes.

Introduction : Les cancers de l’enfant sont rares et représentent environ 1% de la globalité des cancers. Cependant, leur sévérité, la durée de leur traitement et leur évolution au long cours en font un problème de santé publique majeur. Le but de notre étude était d’évaluer les connaissances, attitudes et pratiques des agents de santé de la ville de Ségou sur les cancers de l’enfant. Méthodologie : Il s’agissait d’une étude transversale, descriptive et analytique menée auprès des agents de santé de la ville de Ségou. Résultats : Trois cent dix agents de santé de la ville de Ségou ont répondu à notre questionnaire dont 32 médecins généralistes, 31 médecins spécialistes, 32 assistants médicaux, 41 infirmiers du second cycle, 88 infirmiers de premier cycle, 44 aides-soignants et Matrones, 13 techniciens de laboratoire 29 sages-femmes Les agents de santé qui ont déclaré que les cancers de l’enfant sont des affections malignes représentaient 55,16%. Dans notre étude, 73,5% des agents de santé déclaraient n’avoir pas suspecté ou diagnostiqué un cancer de l’enfant durant leur carrière, 75% n’ont jamais participé à la prise en charge d’un enfant atteint d’un cancer au cours de leur carrière. Conclusion : Le domaine de l’oncologie pédiatrique est méconnu des agents de santé de la ville de Ségou, en tant que 1ers contacts lors de l’apparition de symptômes pouvant faire évoquer un cancer. La discipline est peu enseignée dans le cursus de formation des agents de santé au Mali.

Abstract Carcass data that is collected using ultrasound contributes to national genetic evaluation of beef cattle. Cattle are scanned by many technicians and the resulting images are processed by three laboratories providing data to breed associations. The Ultrasound Guidelines Council certifies technicians and laboratories as being proficient. However, there has been no comprehensive evaluation of non-genetic sources of variation that affect the data. The objective of this study was to partition the variance of ultrasound carcass measurements to animal genetic effects, ultrasound scanning technician and image interpretation laboratory. Ultrasound carcass data for longissimus muscle area, percent intramuscular fat, and subcutaneous fat depth were provided by the American Angus Association (n=65,971), American Hereford Association (n=43,380), and American Simmental Association (n=48,298). For each breed variance components were estimated for additive genetic effects of each animal, technician, contemporary group nested within technician and residual. Genetic correlations were estimated treating measurements from the different interpretation laboratories as separate traits. Across all three breeds, additive genetic effects explained between 15 and 30%, 11 and 25%, and 6 and 13% of the phenotypic variance for IMF, SQF, and LMA, respectively. Similarly, technician explained 12-27%, 4-28%, and 4-26% of the phenotypic variance; contemporary groups within technician accounted for 25-45%, 20-54%, and 43-73% of phenotypic variance. Among the image interpretation laboratories, the ratio of greatest to least residual variance was 3.96, 1.62, and 1.50 for IMF, SQF, and LMA, respectively. Genetic correlations between labs ranged from 0.79 to 0.95 for IMF, 0.64 to 0.94 for SQF and 0.78 to 0.98 for LMA. These results suggest the potential for the residual variances to be heterogeneous, particularly for IMF, depending on the image interpretation laboratory.

ABSTRACT Aim The aim of the survey conducted in dental laboratories was to evaluate the current trend in fabricating a full ceramic restoration for discolored anterior teeth through a questionnaire and personal interaction with the dental technician. Materials and Methods The survey questionnaire consisted of 20 questions aimed toward the current trend in fabricating a full ceramic restoration for discolored anterior teeth. This questionnaire was validated by a panel of senior prosthodontists and technicians and was sent to 32 dental technicians in Mumbai and Navi Mumbai. Results and conclusion The results of the study showed that majority of the dental technicians preferred taking the stump shade themselves by visiting the clinic or inviting the patient to the laboratory. Majority of the dental technicians preferred using lithium disilicate material and its medium opacity ingots to fabricate restorations by the layering technique for masking discolored anterior teeth. Majority of the technicians believed that their dentists did not use try-in paste prior to luting of the restoration. Clinical significance This survey would help to improve the rapport between the clinicians and dental laboratories and optimize the esthetics of the restorations fabricated for anterior discolored teeth.

Background/Aim: Dentist-technician communication is crucial for a successful working relationship in the healthcare setting that contributes to positive health outcomes. However, the interruption of the dentist and the technician communication can harm the dental care procedure. Besides, mistakes in dental laboratories can be both expensive and time-consuming. Materials and Methods: This research project focused on paper-based communication in the dental laboratory setting and its impact on the quality of prosthesis of zirconium crowns. The study's findings suggested that ineffective communication between technicians and dentists resulted in poor quality of zirconium crowns. The study adopted quantitative analysis, which entails a purposive non-probabilistic sampling of dentists targeted located in Texas. Statistical measurements such as Pearson's correlation employed in determining the association between the independent and dependent variables. Results: The research results suggest a significant positive correlation between inter-professional communication in the dental care setting and prosthetic treatment quality. The results also underscore the effectiveness of prep guides in improving the communication between the technicians and the dentist. Conclusions: The researchers conclude that adherence to prep guides contributes to the quality of zirconium crowns and productive communication among dentists and technicians.

Purpose: The practice of pharmacy and role of pharmacists has evolved over the decades but markedly since the introduction of the Affordable Care Act (ACA) in 2010. The ACA allowed patients to have increased access to community pharmacy services, such as medication therapy management, leading to an increase in the clinical services provided by pharmacists. This expansion of pharmacist’s roles has led to pharmacists to feel an increase in workload which negatively impacts the time spent with patients. One way for this shift to occur without continuing to increase the pharmacist’s workload is by using technicians as pharmacist extenders to take on more technical tasks.
Summary: The role of pharmacy technicians has been slow to expand from fear of public safety due to the lack of required education and training. Today, state requirements to practice as a pharmacy technician have become stricter with state requiring licensing, registration or certification. This increase in requirements as led to the expansion of pharmacy technician duties. Studies show that pharmacy technicians are able to perform technician accuracy checking, provide immunization and perform Clinical Laboratory Improvement Amendments (CLIA)-waived screenings. In addition to these duties, pharmacy technicians are being utilized in more novel ways such as collecting medication information in primary care and telepharmacy settings.
Conclusion: In order for pharmacy to continue to grow as a profession, pharmacists need to use pharmacy technicians as extenders. As pharmacy technicians begin to take on more of the technical duties, pharmacists are able to increase the time spent with patients.

The profession of "dental technician" appeared relatively late. The first dental technicians were trained by dentists and worked for them. Gradually, they separated as master owners of the studios and began to hire and train apprentices and journeymen. This time has long been forgotten. After 1997, a dental technician became a person who acquired the right to practice the profession after three years of college education.
At the end of the 19th and the beginning of the 20th century, the profession began with private initiative, passed through state and municipal ownership of dental laboratories, in order to return, for the most part, back to private initiative. Our goal is to study and present demographic characteristics, professional status and qualifications of practitioners in the specialty. To achieve this goal, we studied literature sources, regulations and conducted a sociological survey involving 360 dental technicians. The respondents are from 25 regional colleges of the Bulgarian Association of Dental Technicians, from which we received permission to hold it. We found that the class is relatively aging, which is in line with the demographic problems in our country and in the countries of the European Union. The profession is dominated by men, managers of dental laboratories, who for the most part are registered as Independent Medical and Technical Laboratories. A relatively large number of dental technicians periodically attend postgraduate courses to meet the ever-increasing demands of dentists and patients.

The amount of laboratorypercentage affects the large number of laboratory. Eachlaboratory has a laboratory responsible (technician) in charge ofrecording and monitoring the completeness and condition of thepracticum equipment. Tools and materials used in the process ofpracticum is an asset and laboratory inventory that must alwaysbe maintained and checked the condition of the equipment. InUjung Pandang State Polytechnic (PNUP) in terms of assetmonitoring and practicum inventory is still done manually.Therefore need to make an application to monitor assets andlaboratory inventory, especially on campus two.

Working in a dental laboratory risks exposure to chemicals or infectious materials. One of the activities in the dental laboratory is denture manufacturing. Dental impressions, prostheses, or improper handling of clinical materials in the dental laboratory might contaminate dental technicians with pathogenic microorganisms. Dental technicians should have basic knowledge of the transmission of infection through the dental laboratory to prevent the transmission of infectious agents from dental impressions. This research aimed to discover the level of infection prevention behavior of dental technicians in dental laboratories in Yogyakarta. This research is observational descriptive research that employs a cross-sectional design. The samples were 55 dentaltechnicians working in the three Dental laboratories in Yogyakarta. The instrument was a questionnaire used to measure the level of knowledge. The data were analyzed using univariate (descriptive). According to the findings, almost half of the respondents (42%) had a low infection-prevention behavior level. The conclusion of level infection prevention behavior among dental technicians in Yogyakarta's dental laboratories was common.

BACKGROUND The success of fixed dental prosthesis (FDPs) delivered to the patients depends upon the implementation of appropriate laboratory procedures and dental materials which are required during fabrication of that prosthesis. Inappropriate technique during its fabrication may not always hamper the esthetic end results or fit, but may also hamper the longevity as well. Thus, knowledge about the dental materials as well as the basic laboratory procedures among the dental laboratories should be regularly assessed to assure good quality work. This survey was conducted to assess the knowledge among laboratory technicians regarding the routinely used laboratory procedures and materials for fabrication of FDPs in dental laboratories in Western Maharashtra region with the help of a validated questionnaire. METHODS An electronic survey was conducted with the help of a validated questionnaire that was circulated to 49 laboratories in Western Maharashtra region. The feedback was gathered from laboratory technicians and was then statistically analysed to achieve the objectives of the study. RESULTS 48.8 % of laboratories confirmed that technicians working for them were registered under the state council. 51 % agreed that they only used dental materials that were American Dental Association (ADA) specified. The most common gypsum product for pouring of impressions was dental stone. 65.9 % of the technicians agreed that they inspected the cast before starting the fabrication procedure. Die preparation and ditching procedure was done by 52.9 % and 35.7 % laboratories respectively. Only 38.1 % agreed of using beryllium free alloy ingots; in 66.7 % laboratories, ceramic work was carried out in a separate ceramic room with 76.2 % having adequate ventilation provisions. CONCLUSIONS Response of technicians in Western Maharashtra region regarding their knowledge about basic laboratory procedures in FDP fabrication indicates several areas of weakness. Avoiding such inadequacy in laboratories can significantly reduce FDP failure rates. KEY WORDS Fixed Dental Prosthesis, Dental Laboratory, Survey

Objective: Transport of blood and saliva-contaminated materials such as impressions and prostheses between clinics and laboratories increases the risk of cross-infection. This study evaluates dental technicians knowledge, attitudes, and behaviors about infection control practices. Methods: This cross-sectional study was conducted through an online questionnaire for dental technicians working in Istanbul between July 03, 2021, and January 31, 2022. The questionnaire comprised 38 multiple-choice questions on demographic information, infection control awareness, disinfection practices, personal protective equipment use, and Hepatitis B vaccination. Results: In the research, 256 dental technicians took part, and 73% of them graduated from were graduates of dental lab technician school. The rate of those who received infection control training was 60.2%. 72.3% of the participants were vaccinated against hepatitis B, and 8.6% were not vaccinated due to their immunity. 59.4% of dentists did not inform the laboratories about the sent materials disinfection status. Although 97.3% of the technicians thought there was a risk of infectious disease transmission from impressions and prostheses delivered from dental clinics, they disinfected 88.7% of the alginate impressions and 87.5% of the silicone and polyether impressions. The rate of those who used all the equipment, gloves, masks, and eye protection during disinfection was 31.7%. Medical wastes were separated in 40.6% of the laboratories. 69.9% of technicians thought the infection control procedures were adequate in their laboratories, whereas 20.7% did not. Conclusion: It would be beneficial for dental technicians to receive infection control training to increase their knowledge about disinfection practices and the use of personal protective equipment. We suggest that contaminated materials be transported to laboratories after being disinfected at dental clinics, infection control guidelines for dental prosthesis laboratories should be established, and regular inspections should be conducted to reduce the risk of cross-infection.

Two binder technician workshops were held in January 1998, one at the Connecticut Advanced Pavement Laboratory at the University of Connecticut and one at the Northeast Center of Excellence for Paving Technology at Pennsylvania State University. These workshops were followed by a second set in 1999. The overall objective was to improve the repeatability of the test methods used to grade Superpave® asphalt binders. During the workshops, participants demonstrated and discussed the techniques used in their own laboratories. A document, Manual of Practice for Testing Asphalt Binders in Accordance with the Superpave PG Grading System, was developed for use by asphalt binder technicians and as a training aid for a proposed binder technician certification program. The results of the discussions that were held during the workshops and the items that are presented in the manual of practice are summarized. The results were grouped into four main categories: ( a) handling, sampling, and sample preparation; ( b) temperature measurements; ( c) equipment calibration; and ( d) testing procedures. The items discussed here and in the manual of practice supplement and clarify the current AASHTO test methods. The test methods in themselves are not sufficient to ensure uniformity in testing practice from one laboratory to the other.

Each laboratory has a person in charge (technician) that has a duty of serving the laboratory in term of operational and maintenance. The main task of a technician is to record and monitor the condition and completeness of laboratory equipment in the laboratory. The data collection process is done by writing a tool request form, therefore mistakes often occur. In this research, an Android-based laboratory asset monitoring and inventory application was made. By using the application, it is expected that technicians become easier to make any duties of reports including report of damaged laboratory equipments, request for reparation, the unavailable practical materials etc simply by using a Smartphone. Testing the application with the Black-Box testing method to investigate the function of each application component whether it is running well or not. The results obtained from the Black-Box test are the functions of each component were running as expected. The case study is conducted for Electrical Engineering Department at State Polytechnic of Ujung Pandang (SPUP)

The problem and the aim of the study. Safety of university laboratories is of paramount importance. Performing hands on in a university laboratory can be considered as work with lower risks if compared with other processes in the industries. Yet, it is revealed that there are still many accidents that results in injuries or even fatalities to the staffs and students. More effort particularly in laboratory management is required to minimize the occurrence of laboratory accidents. Research methods. This study evaluated perception of laboratory technicians working in several university electrical and electronic laboratories located in the four states of Northern Region of Malaysia regarding the implementation, effectiveness and challenges on the implementation of 5S practice using cross-sectional survey. The instrument used for data collection was a questionnaire that has been developed and validated by four experts with background of occupational safety. Population of this study was 111 electrical and electronic laboratory technicians from universities in Northern Region of Malaysia. Questionnaire was distributed to all the laboratory technicians and the response rate was 76.6%, where 85 laboratory technicians returned the questionnaire. Kruskal-Wallis H test was used to compare the perception of laboratory technicians among the four states. The level of significance is 0.05. Results. Around 54% of the respondents have more than 3 years working experience 59% of the electrical and electronic laboratories in the Northern Region of Malaysia have an average usage of 10 to 20 hours per week, with 81% have an average of 2 to 4 courses per semester. Approximately 49% of the electrical and electronic laboratories occupied 21 to 30 students per session. Kruskal-Wallis H test for the implementation of 5S practice showed that there was no statistically significant difference in the four states but the test reported statistically significant differences between the mean ranks of at least one pair of groups for effectiveness and challenges of 5S practice. Dunn-Bonferroni post hoc test was employed to further identify the states that were different significantly in the mean rank of scores. Conclusion. Findings from this study give information about the level of implementation, effectiveness and challenges faced by the laboratory technicians working in several university electrical and electronic laboratories located in Northern Region of Malaysia. It can be seen that the knowledge delivered to the students might be similar in the implementation of 5S practice, resulting in a similar level of implementation. Intriguingly, effectiveness of 5S practice resulting from similar implementation of 5S practice in the electrical and electronic laboratories was not the same as it might be affected by other factors. Future study will be focusing on understanding the challenges faced by the laboratory technicians so that the authorities such as the university management could identify the challenges faced by the laboratory technicians in their own university while taking appropriate actions to support the implementation of 5S practice in the laboratory.

Introduction: The assessment of dermal exposure is a complex task. The most commonly used methods have fundamental problems, and there are large gaps in the documentation and validation of the known assessment methods. This study aimed to determine the prevalence of self-reported skin problems in laboratory technicians. Additionally, to determine if there is an association between self-reported skin problems and work tasks and other exposure-related parameters, we developed a simple qualitative questionnaire that may be used for conducting qualitative dermal exposure assessments. Methods: A well-structured survey questionnaire was developed and 45 laboratory technicians were interviewed while conducting qualitative dermal exposure assessments in three selected laboratories. The sampling technique was a qualitative survey conducted through interviews. The examined variables included skin problems, work characteristics, and chemicals used. Results: This study indicated that 18% of technicians reported having skin problems, most notably inexperienced technicians or technicians with more than 6 years of experience. Skin problems were also identified in technicians who worked between one and eight hours, performed manual operations, and handled solvents. The prevalence of skin problems has also been associated with changing gloves. However, no significant differences were observed between the examined parameters and skin problems (p > 0.05). Conclusion: The prevalence of self-reported skin problems (18%) among laboratory technicians was not high. The prevalence of dry skin was low (11%). A well-structured questionnaire can be used to conduct a qualitative dermal risk assessment. As this was a cross-sectional study with a small sample size, it was not possible to establish a causative effect between exposure to workplace hazards and dermal problems.

(1) Background: The success of prosthetic treatment with implant support depends on the combined effort of the team doctor-technician, each of them being responsible for the validation of execution stages. (2) Methods: we composed an online questionnaire with 18 multiple choice questions, using the Google Forms application. It was filled out by an equal number of prosthodontic specialists and dental technicians. Differences and associations were evaluated by Likelihood Ratio test, Linear by Linear association test, Kruskal-Wallis H test, Pearson Chi-Square test and the Fisher’s Exact test. (3) Results: Differences and similarities were found between the statements of prosthodontic specialists and dental technicians. Years of experience are correlated with the number of restorations, impression techniques and types of restoration (p ≤ 0.05). Similar answers for both groups were registered for preferred screw retained type of prosthetic abutment and most frequently reported complications. (4) Conclusions: The different perspectives of the two members of the prosthodontic team regarding the leading role in the treatment plan, type of abutment, impression technique and prosthetic design of implant fixed restorations has been revealed in our study. Similar education curricula and standards for continuing training courses after graduation are necessary for prosthodontic specialists and technicians in Romania.

Vivien Theodore Thomas (1910–1985) was an African-American laboratory technician and instructor of surgery at Johns Hopkins University, Baltimore. He was born as the grandson of a slave in Lousiana, working as a carpenter and subsequently as a laboratory technician after the great depression and the loss of his savings derailed his plans to become a doctor. In his role as a laboratory technician, he overcame challenging personal circumstances to become an innovator in paediatric cardiac surgery, despite having no formal college education. He played an important role in assisting Alfred Blalock and Helen Taussig in the development of the ‘Blalock-Taussig’ shunt, a procedure used to improve the survival of children with cyanotic congenital heart defects. He also contributed to major breakthroughs in research covering a spectrum of disorders such as traumatic shock, coarctation of the aorta and transposition of the great arteries. He acted as a teacher and mentor to a generation of surgical residents and technicians who went on to become leaders in their field across the USA. A television film based on his life was premiered by HBO in 2004 titled ‘Something the Lord made’.

Abstract Background: Instruments for self-monitoring of blood glucose (SMBG) are increasingly used by patients with diabetes. The analytical quality of meters in routine use is poorly characterized. Methods: We compared SMBG performance achieved by patients and by a medical laboratory technician. Imprecision was calculated from duplicate measurements, and deviation as the difference between the first measurement and the mean of duplicate laboratory-method results (calibrated with NIST material). Analytical quality for five groups of SMBG instruments was compared with quality specifications for BG measurements. All participants completed a questionnaire assessing both SMBG training and use of the meters. Results: We recruited 159 SMBG users from a hospital outpatient clinic and 263 others from 65 randomly selected general practices (total of 422). Most (two thirds) used insulin. CVs for the five meter types were 7%, 11%, 18%, 18%, and 20% in the hands of patients and 2.5–5.9% for the technician. For three of five meter types, patients’ BG measurements had larger deviations from the laboratory results than did the technician’s results. The technician’s performance could not predict the patients’. No instrument when used by patients (but two operated by the technician) met published quality specifications. The analytical quality of patients’ results was not related to whether they had chosen the instruments on advice from healthcare personnel (one-third of patients), were only self-educated in SMBG (50%), or performed SMBG fewer than seven times/week (62%). Conclusions: The analytical quality of SMBG among patients was poorer than, and could not be predicted from, the performance of the meters in the hands of a technician. We suggest that new instruments be tested in the hands of patients who are trained on meter use in a routine way.

Background: Recommendations were developed for pulmonary function test (PFT) laboratories during the Coronavirus Disease 2019 (COVID-19) pandemic. However, it is unknown whether these recommendations are effective and safe. Aim of the study: To assess how effective and safe the recommendations for PFT laboratories were during the COVID-19 pandemic. Material and methods: This is a single-center, questionnaire-based study performed between June and August of 2020 at the Akdeniz University hospital. We performed the questionnaire over the phone with technicians from different centers in Turkey. We asked the age, gender, years on the job, routines performed during the pandemic, how many PFTs per day they performed, features of the test room, use of personnel protective equipment, whether they performed triage before the test, and the results of those who had a COVID polymerase chain reaction (PCR) test or a COVID antibody test. Results: A total of 74 technicians from 69 centers were included in the study. Of the centers, 67 (90.5%) were located in tertiary hospitals. At the beginning of the pandemic, 65 (94.2%) centers closed for an average of 2.15 months. The average number of tests performed per day was 14.41 ± 11.88. All centers triaged patients before performing the tests. In 19 (27.5%) centers, a transparent nylon separator was placed between the patient and the technician. Two (0.27 %) technicians tested positive for COVID using PCR testing. Among the 12 (16.2%) technicians screened for COVID-19 antibodies, none of them were found to have COVID-19 antibodies. Conclusion: The recommendations for PFT laboratories seemed to be effective and safe, and the adherence to these recommendations by the technicians was optimal.

Historians have generally confined Liebig's students and assistants to a peripheral role in the development of his Giessen laboratory. This paper argues that these young chemists were essential to Liebig's early success, fulfilling his need for experimental work and producing the apparently independent publications which established the credibility of his new method of organic analysis. Liebig's students and assistants embodied a particular solution to the provision of technician labour and they show us that the technician's role vastly transcends the merely manipulative. The technician, just as much as the scientist, has a history—albeit one that remains largely untold.

Background: The dentist who handles a broken acrylic resin denture base case will send the denture to be repaired by a dental technician in the dental laboratory. The transfer of work is likely to pose a risk of cross-infection (for example AIDS, hepatitis, tuberculosis, pneumonia, and herpes. Purpose: To transfer science and technology based on community needs objectively to get a strong foundation in implementing health management for dental technicians. Methods: Training on how to use disinfection materials as well as participatory counseling using slides through LCD projectors, and using props along with interactive discussions and also mentoring when trainees take disinfection measures. Results: The implementation includes 3 activities, that is counseling, training and monitoring Counseling is carried out by providing knowledge about how to disinfect dentures, then training in how to do disinfection, the way is to train dental technicians to disinfect using chlorhexidine by spraying on the denture surface, then monitored. Conclusion: So far the dental laboratory has not carried out any disinfection at the time of denture repair. With counseling and training in this community partnership program, dental technicians know the importance of disinfection denture to prevent cross infection, so that it will then do it.

PT. MRK Diagnostics is a company engaged in the health sector, especially the provider of medical laboratory equipment in Indonesia. Determination of technicians who are currently running to deal with damage to medical devices is still ineffective because the determination is still checking the availability of technicians manually, so that it will make handling the damage slower. Therefore we need a system that can assist in determining the person in charge technicians to repair the tool. So that in determining the person in charge, this technician will be able to be done precisely and quickly. The criteria used to determine PIC are expertise, discipline, communication and years of service. Each criterion has sub-criteria as well as predetermined weights and values. The decision support system to determine the person-in-charge technicians for medical device repair uses an exponential comparison method that generates a list of priority technicians to perform equipment repair based on calculated and compared values System testing is carried out on information systems experts and users using a questionnaire instrument. Based on expert information systems testing, this system is declared very feasible with a value of 91.7% of the results of system expert testing and 80% based on user testing.

Introduction: Biosafety during lab work is an important concern in developing countries. Some critical issues concerning biosafety are lack of training, exceeding workload, working too fast, deciding not to follow safe practices, and skepticism about biohazards. This study aimed to determine biosafety perception and practices of laboratory technicians during routine work in clinical laboratories of Pakistan. Methodology: A total of 1,782 laboratory technicians were interviewed from major public sector hospitals and a few private hospital laboratories throughout Pakistan. Results: A total of 1,647 (92.4%) males and 135 (7.6%) females participated in the study, with over half (59.7%) having more than five years of work experience. Results showed that 28.4% of the laboratory technicians from Punjab, 35.7% from Sindh, 32% from Balochistan and 38.4% from Khyber Pakhtoon Khawa (KPK) did not use any personal protective equipment. Almost 46% of the respondents (34.2% from Punjab, 61.9% from Sindh, 25.2% from Balochistan and 85% from KPK) said they reused syringes either occasionally or regularly. Furthermore, 30.7% of the respondents said they discard used syringes directly into municipal dustbins. The majority (66.7%) claimed there are no separate bins for sharps, so they throw these in municipal dustbins. Mouth pipetting was reported by 28.3% technicians. Standard operating procedures were not available in 67.2% labs, and accident records were not maintained in 83.4%. No formal biosafety training had been provided to 84.2% of the respondents. Conclusion: Laboratory technicians in Pakistan lack awareness of good laboratory practices and biosafety measures, and also face a lack of resources.

Repetitive tasks performed in a commercial laboratory potentially expose lab technicians to repetitive-motion stresses and strains. Our goal was to reduce or eliminate the risk of injuries through design strategies, such as automation, changes in work flow, system design improvements, or ergonomic assist tools. This article describes six undergraduate biomedical engineering student design innovations conceived for solving challenging ergonomics problems at Covance Laboratories in Madison, Wisconsin. Their designs tackled laboratory procedures for administering substances, sampling blood, removing container lids, vortex mixing, cage opening, and automated bioanalytical test tube uncapping. The successful designs were built, tested, and put into practice.

Abstract HIV viral suppression through antiretroviral (ARV) treatment has public health benefits in potentially reducing the risk of subsequent HIV transmissions. Mozambique has adopted the World Health Organization (WHO) “Test and Start” strategy, which assumes that all people who test positive for HIV start ARV treatment immediately. In order that treatment is guided by the respective HIV viral load (VL) test results, the MOH expanded the network of VL testing laboratories. About 26 VL testing instruments are now operational in the country. Although the increase in testing platforms increased VL tests performed, problems associated with errors, failures in user maintenance, and equipment malfunctions occur frequently. Delays in resolving equipment malfunctions contributed to lower laboratory productivity in certain periods of 2018. Therefore, the MOH, in coordination with the American Society for Clinical Pathology (ASCP) and VL testing instrument manufacturers, provided targeted training for VL laboratory Super Users (SUs). The SUs are primarily composed of laboratory technicians representing all VL laboratories. Training focused on equipment maintenance, software configuration, and troubleshooting the most common instrument-related problems and errors. Following this training, the SUs worked as in-laboratory equipment supervisors, helping laboratory staff to better perform equipment maintenance procedures. Furthermore, they worked remotely with representatives and field technicians of the instrument manufacturers to resolve small problems, such as accessory replacement and adding new users to the systems, in their own laboratories. This has led to a reduction in the overall time to equipment repair, less reliance on external field technicians, and correspondingly increased overall lab productivity and workforce capacity building for VL laboratory SU.

People experience cognitive dissonance when they entertain 2 conflicting ideas at the same time. Cognitive dissonance may cause a negative emotional state, which can lead to engagement of compensation mechanisms to resolve the conflict. Here we describe a survey that explores cognitive dissonance in laboratory animal veterinarians and veterinary technicians and various ways in which veterinary staff manage dissonance associated with research animal use. Respondents—164 veterinarians and 145 veterinary technicians—were asked to rate their opinions of various statements on a sliding scale of 'strongly disagree' to 'strongly agree' or 'never' to 'always.' Statements assessed negative emotions (discomfort, powerlessness, frustration) and compensation mechanisms (devaluing, emotional distancing, shifting responsibility) as bases for inferring effects on welfare states of animals. Responses were evaluated overall and were compared according to level of training (veterinarian compared with veterinary technician), years of work experience (0 to 5, 6 to 10, greater than 10), and species tended (large, mixed, small species). Respondents strongly agreed that animal wellbeing and animal use in research were important. Respondents reported feelings of discomfort, powerlessness, and frustration associated with work. In addition, respondents reported feeling empowered to initiate changes affecting animal welfare. The most frequent compensation mechanism noted was shifting responsibility onto the IACUC and institutional rules. Devaluing the animals was another reported compensation mechanism. Responses to emotional distancing statements were divided. Survey responses supported the existence of cognitive dissonance associated with laboratory animal medicine. Potential negative and positive effects on animal welfare are discussed.

Clinical examinations are a key component of all toxicology studies and are a major component of the functional observational battery (FOB). The FOB is a core feature of the USEPA neurotoxicity screening guideline of 1991. The need for well-trained technicians is recognized, but technician competency is virtually always judged subjectively by their supervisors. Although subjective evaluation of performance cannot be replaced, what constitutes satisfactory performance is nebulous and therefore difficult to communicate to trainees and difficult to document. Consequently, a laboratory performance standard, with a clear pass-fail criterion, was developed to address this deficiency. The performance standard was an idealized composite of FOB data from experienced laboratory personnel, each person tested on a separate set of four groups of rats. The rats were examined in random order, and treatments were either (a) saline, (b) chlorpromazine, (c) atropine followed by physostigmine, or (d) amphetamine. Thus, the performance standard was the pattern of scores generated by the four treatments. After training, each technician was individually tested on four groups of rats similarly treated (random order, blind examination). The pattern of scores generated by the technician was compared to the performance standard by calculating a Pearson's cross-correlation coefficient. An r > 0.8 was considered passing. The use of the standard meets several laboratory goals: (a) good science (improved training leads to better studies), (b) documentation of observer competency required by the USEPA neurotoxicity guideline, (c) improved documentation of training for Good Laboratory Practices, and (d) objective documentation of performance for purposes of personnel management.

Introduction: Dental professionals are at the risk of exposure to wide varieties of microorganisms from blood and saliva of patients to airborne infection from microbial-laden aerosols and spatter created during laboratory procedures. Dental laboratories are usually disregarded when planning effective infection and exposure control measures. Contaminated impression may act as a vehicle for transmission of infectious agents.
Objective: The objective of this study was to assess the practice of dental technicians towards infection control and to evaluate practice of the same for dental impressions in commercial dental laboratories.
Methods: Self-administered standard questionnaire was distributed to 35 dental laboratories and 31 participated in the study. The answers were collected by the investigators themselves. The data obtained were computed and analysed to find the results.
Results: Among all dental laboratories, 21 (67.75%) ensure dental impression is disinfected in clinic. 18 (58.06%) wear gloves when receiving clinical items and 27 (87.10%) transfer the items in separate sealed plastic bag. Of all, 25 (80.64%) of the dental laboratories have separate receiving area for dental impression and 23 (74.19%) of the dental technicians continue to wear protective barriers (gloves, mask and apron) during work. In total, 29 (93.55%) of the dental laboratories confirmed, none of their technicians has ever attended any course or training in cross-infection control.
Conclusion: The practice of cross-infection control for dental impression in commercial dental laboratories is acceptable. There should be proper guidelines from the regulating body on the protocol of infection control and laboratory waste disposal.

Laboratory technicians are a vital part of any working lab. Not only is their knowledge and expertise important for the success of research, but they also often maintain the lab's intellectual and social life. Despite the importance of their work, they are rarely acknowledged in publications, and leave only a few traces within the historical record—the voices of women laboratory technicians are even harder to uncover. This paper attempts to correct this imbalance by presenting the narratives of women who worked as laboratory technicians at places such as the National Institute for Medical Research (NIMR), the Wellcome Research Laboratories, and established hospital and university labs in Cambridge, Oxford and London. The data were collected though narrative interviews. Specifically, the paper looks at the roles of these women within the lab, their experiences of the social and gender dynamics of the lab, and the development of expertise in regard to the work they carried out and the extent to which they received credit for their contributions to science.

New technologies can upset scientific workplaces’ established practices and social order. Scientists may therefore prefer preserving skilled manual work and the social status quo to revolutionary technological change. For example, digital imaging of rock-encased fossils is a valuable way for scientists to “see” a specimen without traditional rock removal. However, interviews in vertebrate paleontology laboratories reveal workers’ skepticism toward computed tomography (CT) imaging. Scientists criticize replacing physical fossils with digital images because, they say, images are more subjective than the “real thing.” I argue that these scientists are also implicitly supporting rock-removal technicians, who are skilled and trusted experts whose work would be made obsolete by widespread implementation of CT scanning. Scientists’ view of CT as a sometimes useful tool rather than a universal new approach to accessing fossils preserves the laboratory community’s social structure. Specifically, by privileging “real” specimens and trusted specimen-processing technicians over images and imaging experts, scientists preserve the lab community’s division of labor and skill, hierarchy between scientists and technicians, and these groups’ identity and mutual trust.

Civil Construction laboratories are the means to conduct student work practices. Civil Construction Laboratory with all equipment and materials is a place of potential cause danger to the users of lecturers, technicians and students in it if not equipped with knowledge about health and Occupational safety. The cost to build occupational safety and health, the cost to buy security tools is quite large. However, occupational safety and health will also be assured. Workers ' skills and skills must be increased through education and training so as to follow the pace of development of science and technology disaster relief tools should be improved to make the catastrophe caused by the implementation of Advanced technology is not until widespread and destructive. But currently the use of safety equipment for the implementation of practice in the Civil Construction Laboratory of Civil Engineering Department of Manado State Polytechnic is still lacking. The specific purpose of dissemination of technological products to the communities to be achieved is (1) protecting and guaranteeing the safety of any lecturers, technicians, students and other people in the workplace; (2) Training K3 for lecturers and Technicians (3) The K3 Handbook for Civil Construction Laboratories. To achieve these objectives, then through the targeted external indicators are: (1) K3 equipment is personal protective equipment (APD) in the form of helmets, masks, vests, gloves and safety shoes (2) K3 Handbook, (3) Training services of K3 for lecturers and technicians and (4) publications on Local on-line mass media.
