Adaptarnos para sobrevivir. Requerimientos de un nuevo paradigma / Adapting to survive. Requirements for a new paradigm

A lo largo de la historia, el rol del bioquímico en el laboratorio clínico ha ido mutando, adaptándose a nuevos paradigmas, consecuencia del avance de la tecnología1 y la informática, de la presión externa ejercida por las empresas proveedoras de reactivos que reducen el tiempo útil de los equipos, aumentando su tasa de recambio, de una medicina más compleja que impone nuevos desafíos diagnósticos y de los cambios sociales que se ven reflejados en una alteración en el orden de los valores adoptado por las nuevas generaciones de profesionales que conviven con otras, provocando "turbulencia generacional" en los lugares de trabajo. Los laboratorios necesitan hoy someterse a una reingeniería de sus procesos, descartar aquellos que no agreguen valor, que causan fugas innecesarias de insumos, personas y tiempo e intervenir la cultura organizacional de manera integral, para adaptarse a las exigencias que la actualidad requiere, donde la calidad, la seguridad y la sostenibilidad son los principales protagonistas )AU)

Over time, the role of the biochemist in the clinical laboratory has been changing, adapting to new paradigms, as a consequence of the advance of technology and informatics, of the external pressure exerted by the companies supplying reagents that reduce the useful time of the equipment, increasing its replacement rate, of a more complex medicine that imposes new diagnostic challenges, and of social changes that are reflected in an alteration in the values adopted by the new generations of professionals who coexist with others, causing "generational turbulence" in the workplace. Laboratories today need to reengineer their processes, eliminate those that do not add value, that cause unnecessary waste of supplies, people and time, and intervene in the organizational culture in a comprehensive manner, in order to adapt to the demands of today's world, where quality, safety, and sustainability are the main drivers (AU)

Performance des explorations cliniques et de l'échographie mammaire dans le diagnostic des tumeurs bénignes du sein en milieu peu équipé d'Afrique subsaharienne / Performance of clinical investigations and breast ultrasound in the diagnosis of benign breast tumors in low-resource settings in sub-Saharan Africa

Contexte et objectif. Malgré leur fréquence élevée, très peu d'études ont été menées sur les tumeurs bénignes du sein (TBS) en Afrique subsaharienne. L'objectif de la présente étude a été d'évaluer la valeur diagnostique des explorations clinique et échographique mammaire des TBS en milieu peu équipé. Méthodes. Il s'agissait d'une étude documentaire, sur les TBS suivies aux Cliniques Universitaires de Kinshasa, entre janvier 2016 et décembre 2021. La valeur diagnostique des explorations clinique et échographique mammaire des TBS (sensibilité, spécificité, valeur prédictive négative VPN, VPP, coefficient Kappa) a été calculée en prenant pour référence la découverte anatomopathologique des pièces biopsiques. Résultats. Au total, 81 dossiers de TBS ont été colligés. Le Fibroadénome 58 (71,6 %), la Maladie fibrokystique (MFK) 15 (18,5 %), l'Adénome tubuleux 6(7,4 %), la Tumeur Phyllode (TP) 1(1,2 %) et le kyste 1(1,2 %) étaient les tumeurs diagnostiquées à l'anatomopathologie, après tumorectomies. A l'examen clinique, la capacité diagnostique des TBS autres que le Fibroadénome était nulle. La spécificité, la VPN et le coefficient kappa étaient respectivement, de 60,0 %, 39,1 % et 32,2 % pour le diagnostic du Fibroadénome. L'échographie mammaire était faite dans 98,6 % tandis que la mammographie seulement dans 11,1 % des cas. La majorité des tumeurs étaient classées Breast Imaging reporting and Data system (BIRADS) 2 (70,0 %). La spécificité, la VPN et le coefficient kappa étaient respectivement, de 80,6 %, 40,9 % et 39,0 % pour le Fibroadénome, et de 84,4 %, 66,7 % et 1,9 % pour la MFK. La TP était classée BIRADS3. Conclusion. L'échographie mammaire très réalisée, est très performante dans la classification BIRADS des TBS; les cliniciens exerçant en milieu peu équipé peuvent donc sans équivoque suivre les recommandations sur la prise en charge des tumeurs classées BIRADS2 et BIRADS3 à l'échographie, bien que sa performance en ce qui concerne le diagnostic différentiel de ces tumeurs soit moindre.

Reflexiones sobre los valores éticos de la protección radiológica para los profesionales tecnólogos médicos de imagenología / Reflections on the ethical values of radiation protection for the professional medical technologists in imaging

Las radiaciones ionizantes tienen el potencial de generar efectos adversos a la salud de las personas. Para hacer un uso más seguro y eficiente de estas radiaciones, la Comisión Internacional de Protección Radiológica fundamentalmente ha implementado un sistema de protección radiológica (SPR) que se basa en tres principios: justificación, optimización y límites. A su vez, estos principios se sustentan en cuatro valores éticos (beneficencia, prudencia, justicia y dignidad). Se sabe que en Chile el profesional que esta mandatado para realizar la toma de los exámenes que utilizan radiaciones ionizantes es el/la Tecnólogo Médico en Imagenología. Por lo tanto, resulta interesante valorar el grado de conocimiento adquirido y posteriormente aplicado en torno a los valores éticos del SPR por parte de dichos profesionales. De esta manera el objetivo del este artículo de tipo Punto de Vista fue realizar una serie de reflexiones en torno a esta temática. Cuando se realiza un procedimientos médico u odontológico con radiaciones ionizantes, el/la Tecnólogo Médico en Imagenología participa esencialmente en la realización del mismo, por lo que no debería ser su responsabilidad el cautelar que se cumplan los 4 valores éticos descritos dentro del SPR. A juicio nuestro, el principio de optimización, sería el único principio o pilar del SPR donde tiene real obligación de participar, utilizando las restricciones a las exposiciones individuales y los niveles de referencia para diagnóstico para reducir las desigualdades en la distribución de las exposiciones entre los grupos expuestos. Finalmente, resulta vital investigar si en su formación de especialidad se tocan estas temáticas

Ionizing radiation has the potential to generate adverse effects on people's health. To make safer and more efficient use of these radiations, the International Commission on Radiological Protection has fundamentally implemented a radiological protection system (RPS) based on three principles: justification, optimization and limits. In turn, these principles are based on four ethical values (beneficence, prudence, justice and dignity). It is known that in Chile the professional who is mandated to perform the exams that use ionizing radiation is the Medical Imaging Technologist. Therefore, it is interesting to assess the degree of knowledge acquired and subsequently applied around the ethical values of the RPS by these professionals. In this way, the objective of this Point of View article was to make a series of reflections on this subject. When a medical or dental procedure is performed with ionizing radiation, the Medical Imaging Technologist essentially participates in its performance, so it should not be their responsibility to ensure that the 4 ethical values described in the RPS are met. In our opinion, the principle of optimization would be the only principle or pillar of the RPS where it has a real obligation to participate, using the restrictions on individual exposures and the diagnostic reference levels to reduce inequalities in the distribution of exposures between exposed groups. Finally, it is vital to investigate whether these topics are addressed in his specialty training.

Exactitud de tamizaje de retinopatía diabética: inteligencia artificial versus tecnólogos médicos entrenados / Accuracy of artificial intelligence compared to trained medical technologists in diabetic retinopathy screening

Background: The early detection of retinopathy among diabetics is of utmost importance. Aim: To estimate the diagnostic accuracy of two diabetic retinopathy (DR) screening strategies currently used in the Chilean public health system. Material and Methods: Cross-sectional observational study of 371 diabetic patients aged 61 ± 14 years (61% women) who underwent DR screening at a public Hospital between July 1 and August 31, 2019. The mydriatic retinal photographs of all participants were classified using artificial intelligence software (DART) and trained medical technologists, independently. The precision of both strategies was compared with the reference standard, namely the evaluation of the fundus by an ophthalmologist with a slit lamp. Participants with severe non-proliferative DR or worse were considered as positive cases. The ophthalmologist was blind to the results of the screening tests. Results: Twenty four percent of participants had DR, including 34 (9.2%) who had sight threatening DR in at least one eye. The sensitivity and specificity of DART were 100% (95% confidence intervals (CI): 90-100%) and 55,4% (95% CI: 50-61%), respectively. Medical technologists had a sensitivity of 97,1% (95% CI: 85-100%) and a specificity of 91,7% (95% CI: 88-94%). The only case missed by medical technologists was a patient with unilateral panphotocoagulated DR. Conclusions: Both strategies had a similar sensitivity to detect cases of sight-threatening DR. However, the specificity of DART was significantly lower compared to medical technologists, which would greatly increase the burden on the health system, a very important aspect to consider in a screening strategy.

An analytical cross-sectional study on the knowledge, attitudes, and practices (KAP) on biomedical waste management among nurses and medical technologists in the Philippines / The Health Sciences Journal

INTRODUCTION@#Unregulated biomedical waste management is an emerging public health problem in the Philippines. This study aimed to differentiate the knowledge, attitudes, and practices of nurses and medical technologists toward biomedical waste management.@*METHODS@#Using an analytic cross-sectional study design, an online survey of nurses and medical technologists from hospitals around the Philippines was conducted. A 27-item questionnaire covering knowledge, attitudes and practices was used. The percentages of correct answers and mean scores in each domain was compared between the nurses and medical technologists.@*RESULTS@#A total of 196 respondents consisting of 77 registered nurses and 119 medical technologists were included in the study. Medical technologists had significantly better knowledge scores than nurses on disposal procedures for expired blood units and by-products waste (55% vs. 19%, p = 0.026). Both had low correct responses on adequate disposal of human tissue remains, throwing blood waste into domestic waste, and throwing of expired medications in domestic waste. There was no significant difference in the attitude of nurses and medical technologists. Nurses had significantly better practice scores on disposal of liquid waste in bags (84.4% vs. 68.9, p = 0.018), but medical technologists fared better at disposal of human tissue together with other waste (13.0% vs. 2.5%, p = 0.006). @*CONCLUSION@#Both nurses and medical technologists had adequate knowledge of some aspects but were lacking in others. There was no significant difference in the attitude of nurses and medical technologists towards biomedical waste management. Half of the respondents practiced proper biomedical waste management.

Abstract Introduction: To reach the goal of malaria elimination in Ecuador for the year 2020, it is necessary to have a laboratory network with the capacity to perform microscopic diagnosis according to the WHO/PAHO quality standards and to provide the adequate treatment of cases. Objective: To determine the level of competence for parasitological diagnosis of the microscopists from the local public network and the performance of intermediate reference laboratories. Materials and methods: We conducted a cross-sectional study based on the information collected in workshops carried out to appraise the competence for microscopic diagnosis of the local laboratory network (zonal health coordinating offices 1 to 8) using a slide panel to evaluate diagnosis agreement, as well as the diagnostic performance of the intermediate laboratories using an external quality assessment program. The results were compared against the reference standards of the supranational laboratory in Perú. Results: We evaluated the competencies of 191 microscopists in 11 workshops and 153 (80.1%) of them were approved. The medians of the indicators were the following: concordance for parasite detection, 100% (Q1- Q3: 96-100), concordance for species identification, 100% (Q1- Q3: 93-100), and concordances for stage identification, 93.0% (Q1- Q3: 86-95) and parasite counting, 77.0% (Q1- Q3: 71-82). In the external quality assessment, the three intermediate laboratories obtained 100% in parasite detection concordance and 96% for species detection concordance. Conclusions: The results for the primary network and the performance indicators for the intermediate laboratories showed the high-quality standards of the training program implemented in the country.

Assessment of clinical competences and self-confidence of radiologist and technologist at Asir region hospitals, Saudi Arabia

Background: Evaluating the clinical competencies of radiologist and technologist is the primary important factor in all medical imaging areas, and it is a necessary prerequisite for assuring professional standard care in radiography

Aim: to evaluate clinical competences from the views of radiologists and technologists by applying the Radiographers' Competence Scale [RCS]

Method: A cross-sectional survey conducted on 185 participants recruited from six hospitals of Asir region of Saudi Arabia. All data were collected using the self-administrative questionnaire of 28 items scale of radiographer competence scale consisting of the two components; initial care scale and technical radiographic process. The level of competencies scale was rated through 10 - point and frequency of use on 6 - point scale

Results: The survey completed by 82 [44.3%] radiologist and 103 [55.7%] technologist. Overall mean significant [P < 0.001] differences scores of Initial Care scale observed between radiologist and technologist. However, with reference to technical and radiographic process no mean significant differences were detected between the two groups. The technologist attributed the highest evaluations to such competencies as "Adequately informing the patient" and "Guiding the patient's relatives", while other attributes the lowest evaluations expressed in the competencies. The radiologists attributed the highest evaluations to such competences as "Collaborating with physicians "and "Independent carrying out of the doctor's prescriptions", while the lowest evaluations to the same competences as the technologists

Conclusion: The significant findings underline the radiologist and high technologist competences in both "Initial Care scale "and "Technical and Radiographic Process". However, the lower rated competences emphasis on continuous professional development in the area of medical radiology

Detección temprana de la enfermedad renal crónica: una tarea conjunta entre médicos y bioquímicos / Early detection of chronic kidney disease: a joint effort between doctors and biochemists

La detección temprana de la enfermedad renal crónica es prioritaria para prevenir la epidemia mundial de esta enfermedad con consecuencias devastadoras para el paciente y el sistema de salud. Los dos parámetros utilizados para su detección precoz requieren del trabajo conjunto entre médicos y bioquímicos, dado que, por un lado el médico debe hacer la adecuada solicitud del parámetro a evaluar y, por otro, el bioquímico debe asegurar la calidad de las mediciones que realiza. El índice de filtración glomerular estimado por fórmula está recomendado para la evaluación de la función renal, mientras que la detección de albuminuria es indiscutible como marcador precoz de daño renal. El objetivo principal de este trabajo es demostrar la necesidad del trabajo conjunto entre médicos y bioquímicos para efectuar un diagnóstico temprano de la enfermedad. Palabras Clave: Diagnóstico precoz, insuficiencia renal, Prestación en Atención de Salud.

Early detection of chronic kidney disease is priority to prevent the global epidemic of this disease, with devastating consequences for the patient and the health systems. The two parameters used for its early detection require action shared between physicians and biochemists, actually the physician must make a proper request of the parameters needed, and the biochemist must assure the quality of the measurements he carries out. Glomerular filtration rate equations are recommended for the evaluation of renal function, whereas the detection of urine albumin is an unquestioned parameter as an early sign of renal damage. The aim of this paper is to demonstrate the importance to joint job between physicians and biochemists to make an early diagnosis of the disease. Key words: Early diagnosis, renal insufficiency, delivery of healthcare.

Screening newborns for metabolic disorders based on targeted metabolomics using tandem mass spectrometry

The main purpose of newborn screening is to diagnose genetic, metabolic, and other inherited disorders, at their earliest to start treatment before the clinical manifestations become evident. Understanding and tracing the biochemical data obtained from tandem mass spectrometry is vital for early diagnosis of metabolic diseases associated with such disorders. Accordingly, it is important to focus on the entire diagnostic process, including differential and confirmatory diagnostic options, and the major factors that influence the results of biochemical analysis. Compared to regular biochemical testing, this is a complex process carried out by a medical physician specialist. It is comprised of an integrated program requiring multidisciplinary approach such as, pediatric specialist, expert scientist, clinical laboratory technician, and nutritionist. Tandem mass spectrometry is a powerful tool to improve screening of newborns for diverse metabolic diseases. It is likely to be used to analyze other treatable disorders or significantly improve existing newborn tests to allow broad scale and precise testing. This new era of various screening programs, new treatments, and the availability of detection technology will prove to be beneficial for the future generations.

Em relação ao cargo exercido, 73% atuam como citotécnicos e 70% são funcionários públicos. O trabalho do citotécnico tem especificidade única desse trabalhador de nível técnico, que é a realização da primeira análise do exame citopatológico, com ações articuladas e complementares de natureza técnica, de gestão, e educativas vinculadas à equipe, com ênfase nos princípios de prevenção e promoção da saúde. Por meio da escala de avaliação do contexto de trabalho, foram avaliadas as condições físicas, materiais e organizacionais do processo de trabalho. O quesito clareza, na definição das tarefas, foi o maior valorado com 4,7% de média, seguido das relações socioprofissionais com média de 4,0%. Os resultados da análise de conteúdo revelaram: na trajetória da atividade laboral, emergiram quatro categorias associadas à motivação e ao ingresso na ocupação por pessoas de referência na formação, acesso ao mercado de trabalho, busca pelo aperfeiçoamento profissional e aprendizagem prática no trabalho; no conceito de modo de produção, emergiram cinco categorias: responsabilidade de salvar vidas, crítica em relação ao próprio trabalho com qualidade, características físicas, atividades distintas do citotécnico e do histotécnico, visão do trabalho com otimismo; nas condições de trabalho, emergiram quatro categorias: trabalho em equipe e responsabilidade individual, ambiguidade em relação à autonomia, precarização do trabalho, esperança no reconhecimento da profissão. CONCLUSÃO: O trabalho do citotécnico é uma ocupação fracamente regulamentada, que se caracteriza por ausência de perfil profissional específico compatível com o escopo de prática real observada no trabalho levando a condições de trabalho precário. O reconhecimento ocorre entre os próprios trabalhadores que se valorizam por serem responsáveis pela promoção da saúde tornando seu trabalho socialmente útil.

INTRODUCTION: This study examines the work processes of cytotechnicians employed in Anatomic Pathology and Cytopathology laboratories in Rio de Janeiro State, Brazil. OBJECTIVES: general purpose is: to analyze perceptions among cytotechnicians of the skills needed to perform their jobs; and more specifically: (1) to describe the work activities of cytotechnicians; (2) to identify activity production modes through workplace relationships; and (3) to explore and understand the implications of the work of cytotechnicians on cancer control actions. MATERIAL AND METHODS: Conducted at three Anatomic Pathology and Cytopathology laboratories in Rio de Janeiro State, this qualitative, descriptive and social research project involved 33 cytotechnicians. Obtained between January and August 2014 through semi-structured interviews, questionnaires and focus groups, the data were subsequently analyzed through the Bardin Content Analysis technique, with the theme constituting the record unit. RESULTS: The findings showed that 73% of these 33 cytotechnicians were women and 34% were split equally between two age brackets: 41  50 years old and 51  60 years old. For the education variable, 43% held specialty qualifications and 24% were university graduates. In terms of their positions, 73% worked as cytotechnicians while 70% were civil servants. The work of the cytotechnician has a specific characteristic that is unique to these technical level employees: they handle the initial analyses of cytopathologic tests through tight-knit team-based complementary actions involving technical, administrative and educational aspects, grounded on health promotion and disease prevention principles. The physical, material and organizational conditions of their work processes were assessed on a work-place rating scale. The issue of task definition clarity ranked highest with a 4.7% mean score, followed by social and professional relationships at a 4.0% mean score. The Content Analysis findings showed that four categories appeared for their work-place activities, associated with: motivation and career choices steered by persons of influence while studying; access to the job market; quest for professional enhancement; and on-the-job training using a hands-on approach. CONCLUSION: The production mode concept gave rise to five categories: responsibility for saving lives; criticism of their own work and quality; physical characteristics; activities specific to cytotechnicians and histotechnicians; and positive views of their jobs. Their working conditions resulted in four categories: teamwork and individual responsibilities; ambiguity about autonomy; weak job security; and hope for better professional acknowledgment. The work of cytotechnicians is covered by lax labor regulations, undermining the presence of a specific professional profile compatible with the scope of their actual job routines as observed and resulting in poor working conditions. They affirm they see themselves as buttressing health promotion, appreciatively aware that their work is useful to society.

Prevalence and associated factors of Carpal Tunnel Syndrome [CTS] among medical laboratory staff at King Saud University Hospitals, KSA

Carpal tunnel syndrome [CTS] is a group of symptoms resulting from local compression of the median nerve at the wrist leading to its subsequent functional impairment and local ischemia of the nerve. Our objective was to determine the prevalence and commonly reported symptoms of CTS in the laboratory workers of King Saud University [KSU] hospitals and to identify the associated variables with CTS. This was a quantitative observational cross-sectional study which was conducted in KSU hospitals' laboratories with a total of 225 participants by using a standardized questionnaire known as [Boston Carpal Tunnel Questionnaire [BCTQ]. Data Analysis was carried out by IBM SPSS Statistics software version 21.0. Out of the 225 participants, 57 were found to be severely symptomatic with a prevalence of 25.3%. Among the severely affected participants, females were more than males [58% > 42%] and the difference was statistically significant [p=0.045]. Technicians affected [91.2%] were more than attendants [8.8%] and the difference was statistically significant [p=0.042]. The prevalence of Carpal tunnel syndrome in KSU hospitals' medical laboratory staff [25.3%] was close to what was found in literature [21.5%]. So laboratory workers are at risk of developing CTS, especially females and technicians with the dominant hand most likely to be affected
