Background/Aims: Diagnosing gastroesophageal reflux disease (GERD) is sometimes challenging because the performance of available tests is not entirely satisfactory. This study aims to directly measure the esophageal mucosal impedance during upper gastrointestinal endoscopy for the diagnosis of GERD. Methods: Sixty participants with typical symptoms of GERD underwent high-resolution esophageal manometry, 24-hour multichannel intraluminal impedance-pH monitoring, upper gastrointestinal endoscopy, and mucosal impedance measurement. Mucosal impedance measurement was performed at 2, 5, 10, and 18 cm above the esophagogastric junction during gastrointestinal endoscopy using a specific catheter developed based on devices described in the literature over the last decade. The patients were divided into groups A (acid exposure time < 4%) and B (acid exposure time ≥ 4%). Results: The mucosal impedance was significantly lower in group B at 2 cm (2264.4 Ω ± 1099.0 vs 4575.0 Ω ± 1407.6 [group A]) and 5 cm above the esophagogastric junction (4221.2 Ω ± 2623.7 vs 5888.2 Ω ± 2529.4 [group A]). There was no significant difference in the mucosal impedance between the 2 groups at 10 cm and 18 cm above the esophagogastric junction. Mucosal impedance value at 2 cm > 2970 Ω resulted in a sensitivity of 96.4% and a specificity of 87.5% to exclude GERD. Conclusions: Direct measurement of mucosal impedance during endoscopy is a simple and promising method for diagnosing GERD. Individuals with an abnormal acid exposure time have lower mucosal impedance measurements than those with a normal acid exposure time.
RESUMO
Objectives. The main objective of this study was to evaluate mean propulsive velocity (MPV), mean propulsive force (MPF) and mean propulsive power (MPP) in elite police officers under LOADED and UNLOADED conditions. The study also investigated the association of body composition and strength levels under the same load conditions. Methods. Twenty-one men from an elite unit in Brazil participated in the study, performing Smith machine half squats and an agility test. Dual energy X-ray absorptiometry measured body composition; a linear encoder measured MPV, MPF and MPP during the half squats; and a manual chronometer registered agility test performance. Results. The results showed that wearing and carrying occupational loads did not alter the squat exercise's MPP, MPV and MPF but reduced the performance of relative MPP and agility (p < 0.05). The results also showed that MPP had a higher association with force (i.e., MPF and one-repetition maximum [1RM]) than velocity (i.e., MPV and agility) under the LOADED condition (p < 0.05). Among the body composition variables, only lean body mass was associated with MPP under the LOADED condition (p < 0.05). Conclusion. These findings suggest that load carriage does not reduce absolute mechanical power output, but reduces the relative MPP and agility in military police officers.
RESUMO
This paper explores a data augmentation approach for images of rigid bodies, particularly focusing on electrical equipment and analogous industrial objects. By leveraging manufacturer-provided datasheets containing precise equipment dimensions, we employed straightforward algorithms to generate synthetic images, permitting the expansion of the training dataset from a potentially unlimited viewpoint. In scenarios lacking genuine target images, we conducted a case study using two well-known detectors, representing two machine-learning paradigms: the Viola-Jones (VJ) and You Only Look Once (YOLO) detectors, trained exclusively on datasets featuring synthetic images as the positive examples of the target equipment, namely lightning rods and potential transformers. Performances of both detectors were assessed using real images in both visible and infrared spectra. YOLO consistently demonstrates F1 scores below 26% in both spectra, while VJ's scores lie in the interval from 38% to 61%. This performance discrepancy is discussed in view of paradigms' strengths and weaknesses, whereas the relatively high scores of at least one detector are taken as empirical evidence in favor of the proposed data augmentation approach.
RESUMO
OBJECTIVES: To evaluate potential airborne asbestos exposures during brake maintenance and repair activities on a P&H overhead crane, and during subsequent handling of the mechanic's clothing. METHODS: Personal (n = 27) and area (n = 61) airborne fiber concentrations were measured during brake tests, removal, hand sanding, compressed air use, removal and reattachment of chrysotile-containing brake linings, and reinstallation of the brake linings. The mechanic's clothing was used to measure potential exposure during clothes handling. RESULTS: All brake linings contained between 19.9% to 52.4% chrysotile asbestos. No amphibole fibers were detected in any bulk or airborne samples. The average full-shift airborne chrysotile concentration was 0.035 f/cc (PCM-equivalent asbestos-specific fibers, or PCME). Average task-based personal air samples collected during brake maintenance, sanding, compressed air use, and brake lining removal tasks ranged from 0 to 0.48 f/cc (PCME). The calculated 30-minute time-weighted average (TWA) airborne chrysotile concentration associated with 5-15 minutes of clothes handling was 0-0.035 f/cc PCME. CONCLUSION: The results indicated that personal and area TWA fiber concentrations measured during all crane brake maintenance and clothes handling tasks were below the current OSHA 8-h TWA Permissible Exposure Limit for asbestos of 0.1 f/cc. Further, no airborne asbestos fibers were measured during routine brake maintenance tasks following the manufacturer's maintenance manual procedures. All short-term airborne chrysotile concentrations measured during non-routine tasks were below the current 30-minute OSHA excursion limit for asbestos of 1 f/cc. This study adds to the available data regarding chrysotile exposure potential during maintenance on overhead cranes.

INTRODUCTION AND AIMS: Adequate drying and proper storage of flexible endoscopes are essential for maintaining quality in their reprocessing. The aim of the present study was to evaluate the drying stages, storage, and channel conditions of endoscopes through borescope inspection. MATERIAL AND METHODS: The personnel responsible for endoscope reprocessing were interviewed. Storage conditions at 10 endoscopy facilities were inspected and an internal examination of the channels and ports of the stored equipment was carried out, utilizing a borescope. A total of 74 stored endoscope channels were evaluated. RESULTS: Only 10% of the facilities inspected utilized transport cases for storage and only 10% had rooms exclusively used for storage. Sixty percent of the facilities did not perform any shelf-life control. All the channels evaluated were scratched and fluids were present on 69% of them. CONCLUSIONS: Endoscope reprocessing can be improved through the implementation of drying and storage control and validation tools, as well as the use of borescopes and periodic clinical audits.

OBJECTIVES: To calculate the direct cost of personal protective equipment (PPE) used during the COVID-19 pandemic from the perspective of a Brazilian tertiary public hospital. METHODS: We evaluated the cost of PPE during the pandemic to the cost before (2021 vs 2019, respectively) using the microcosting method. Cost estimates were converted into US dollars in 2023, taking inflation into account and using purchasing power parity conversion rates. Our expenses included gloves, disposable gowns, head coverings, masks, N95 respirators, and eye protection. The number of PPE used was determined by the hospital's usual protocol, the total number of hospitalized patients, and the number of days of hospitalization. We used the following variables for uncertainty analysis: PPE adherence, an interquartile range of median length of hospitalization, and variance in the cost of each PPE. RESULTS: In 2021, 26 618 individuals were hospitalized compared with 31 948 in 2019. The median length of stay was 6 and 4 days, respectively. The total and per-patient direct cost of PPE were projected to be 2 939 935.47 US dollar (USD) and 110.45 USD, respectively, during the pandemic, and 1 570 124.08 USD and 49.15 USD, respectively, before the pandemic. The individual cost of PPE was the most influential cost variable. CONCLUSIONS: According to the hospital's perspective, the total estimated direct cost of PPE during the COVID-19 pandemic was nearly twice as high as the previous year. This difference might be explained by the 3-fold increase in PPE in the treatment of patients with COVID-19 compared with patients without isolation precautions.

BACKGROUND: An increase in the workload and use of personal protective equipment by healthcare workers was observed during the COVID-19 pandemic. Due to the connections between craniocervical structures, symptoms such as neck pain and temporomandibular symptoms could be influenced by the use of PPE. AIMS: To assess the prevalence of craniocervical pain, sleep quality, physical activity, and depressive symptoms and relationship among craniocervical symptoms in healthcare workers before and during the COVID-19 pandemic in Brazil. DESIGN: Cross-sectional study. PARTICIPANTS: Healthcare workers. SETTINGS: An online questionnaire included a self-report of craniocervical pain intensity [orofacial pain, neck pain, and headache (Numerical Rating Scale)], sleep quality (Pittsburgh Sleep Quality Index), depressive symptoms (Patient Health Questionnaire two items) and physical activity (self-report). METHODS: The sample analysis was performed by descriptive statistics, the paired t-test was used to compare symptoms intensity before and during the pandemic. The relationship between dependent and independent samples was assessed through McNemar test, Pearson's chi-squared test, and Student's independent t-test. A value of p < .05 was adopted as statistical significance. RESULTS: Overall, 147 participants replied the questionnaires. Headache, neck pain, and orofacial pain complaints increased during the pandemic in healthcare workers (p < 0.001). Craniocervical pain was correlated with poor sleep quality, probable depression, and physical activity during the pandemic (p < 0.05). CONCLUSION: Healthcare workers self-reported more craniocervical pain during the COVID-19 pandemic compared to before the pandemic. In addition, poor sleep quality, depressive symptoms, and physical inactivity were associated with craniocervical symptoms during this period.

RESUMO
BACKGROUND: Oral cancer (OC) is a multifactorial disease that affects the oral cavity. The mortality rate is approximately 50 % and a high percentage of patients are diagnosed in advanced stages. Early diagnosis has been well demonstrated to improve overall survival, mainly when detected at a localized stage. Non-invasive techniques can help identify malignant features in real time, thus improving the path to diagnosis. This study aimed to perform a bibliometric analysis of the top 100 articles cited on diagnostic aids for oral cancer. METHODS: Articles from 2000 to 2023 in Scopus were scanned using five OC topic titles crossed with 27 diagnostic aid keywords. Duplicate manuscripts were eliminated using Microsoft Excel software and publications were ranked according to their citation count. This study selected and analyzed the top 100 most cited English-language papers. RESULTS: 86,676 citations were accumulated by the top 100 articles most cited. 2011 was the year with the highest number of publications with OC papers. The article with the most citations obtained a total of 30,832. The United States was the country with the most publications, with a total of 45, and UCLA was the institution with the most publications (7) among the top 100 most cited papers. CONCLUSIONS: This study identified the top 100 most cited articles on diagnostic aids for oral cancer. These results can help dentists, specialists, healthcare providers, and researchers become familiar with the most influential publications in this field.

RESUMO
Introducción: La anatomía hepática siempre ha sido un reto por su complejidad y variabilidad. En los últimos años, el abaratamiento de los costes ha permitido la generación de modelos 3D individualizados para cada paciente que pueden facilitar el abordaje quirúrgico de las lesiones. El objetivo principal fue determinar la utilidad del modelado 3D preoperatorio para la planificación quirúrgica en pacientes con lesiones hepáticas. Métodos: Se trata de un estudio de casos de 38 pacientes intervenidos por lesiones hepáticas múltiples ocupantes de espacio, en el cual, en un grupo seleccionado, en 19 pacientes se utilizó un modelo impreso 3D para planificar la cirugía (grupo 3D) y el otro grupo sin el modelo impreso 3D (grupo control). Resultados: Se observó una diferencia de medias significativa en el número de lesiones; mayor en el grupo 3D al realizar el test de Wilcoxon (p < 0,001) y un mayor número de casos con afectación vascular en este mismo grupo al realizar Chi cuadrado Pearson (p = 0,008). El resto de variables no mostraron diferencias estadísticamente significativas. A pesar de esto, la mortalidad se redujo a 0 cuando se usan modelos impresos en 3D. Conclusión: La impresión 3D permite planear, de manera más precisa, cirugías complejas del hígado, ayuda a la inclusión y exclusión de los pacientes para la cirugía, disminuyendo el tiempo de la sala de operaciones, la posterior hospitalización y las complicaciones quirúrgicas.
Introduction: Liver anatomy has always been a challenge due to its complexity and variability. In recent years, lower costs has allowed the generation of individualized 3D models for each patient, which can facilitate the surgical approach to liver lesions. The main objective was to determine usefulness of preoperative 3D modeling for surgical planning in patients with liver lesions. Methods: Quasi-experimental before-after study. 19 cases were included in which surgery was planned using a 3D printed model (13 bilobar hepatectomies, 3 of them with vascular involvement, and 6 unilobar hepatectomies, 1 of them with vascular involvement), and another 19 cases whose planning was carried out without a 3D printed model (7 bilobar segmental hepatic resections and 12 unilobar segmental resections. None of these cases had vascular involvement). Results: A significant difference in mean lesion count was observed, higher in the group of cases when performing the Wilcoxon test (p < 0.001), and a higher number of cases with vascular involvement in the same group when performing the Pearson chi-square test (p = 0.008). The rest of the variables did not show statistically significant differences. Despite this, mortality was reduced to 0 when 3D printed models were used. Conclusion: 3D printing allows for more precise planning of complex liver surgeries, helps with the inclusion and exclusion of patients for surgery, reduces operating room time, postoperative hospitalization, and surgical complications.
RESUMO
This feasibility study evaluates a cleaning process designed to avoid the use of detergents and reduce operator exposure to the active pharmaceutical ingredient (API). The continuous manufacturing equipment was cleaned using excipients to displace ibuprofen residues from the system. The cleaning process was performed using 3.0 kg of Prosolv® and 3.0 kg of Tablettose® 70. The impact of different volumetric feed rates of the cleaning excipient was assessed. The displacement of API and blend residues was evaluated with in-line near infrared (NIR) spectroscopy. Principal component analysis (PCA) was performed to evaluate the cleaning progress as the Prosolv® flowed through the feeder, mixer and stream sampler. In-place Raman spectra were acquired from the material sticking to detect the ibuprofen residues. The study showed that Prosolv® and Tablettose® can remove ibuprofen residues effectively from the hopper, feeder screw, mixer paddles, shaft and stream sampler. The Process Analytical Technology (PAT) system can be utilized to detect API displacement during the cleaning process. However, dismantling and manual cleaning was required to remove material sticking at the surfaces adjacent to the rotating feeder screws and mixer paddles.

Yttrium is a heavy rare earth element (REE) that acquires remarkable characteristics when it is in oxide form and doped with other REEs. Owing to these characteristics Y2 O3 can be used in the manufacture of several products. However, a supply deficit of this mineral is expected in the coming years, contributing to its price fluctuation. Thus, developing an efficient, cost-effective, and eco-friendly process to recover Y2 O3 from secondary sources has become necessary. In this study, we used phage surface display to screen peptides with high specificity for Y2 O3 particles. After three rounds of enrichment, a phage expressing the peptide TRTGCHVPRCNTLS (DM39) from the random pVIII phage peptide library Cys4 was found to bind specifically to Y2 O3 , being 531.6-fold more efficient than the wild-type phage. The phage DM39 contains two arginines in the polar side chains, which may have contributed to the interaction between the mineral targets. Immunofluorescence assays identified that the peptide's affinity was strong for Y2 O3 and negligible to LaPO4 :Ce3+ ,Tb3+ . The identification of a peptide with high specificity and affinity for Y2 O3 provides a potentially new strategic approach to recycle this type of material from secondary sources, especially from electronic scrap.

ABSTRACT Objective: Determine the relationship between the budget execution of financial transfers from the SIS (Seguro Integral de Salud) and the availability of medical supplies in third-level establishments of the Ministry of Health of Metropolitan Lima. Material and method: Analytical and cross-sectional study, carried out in the 20 level III establishments of the MINSA in Lima; Likewise, documentary information was used such as Closing Minutes of Financial Supervision of the Macroregional Management of the SIS from which information on budget execution was obtained and the availability of medical supplies was obtained from the Mundo IPRESS web portal (Institutions Providing Health Services). After evaluating normality with the Shapiro-Wilk test, the Spearman correlation test was used. Result: Overall budget execution was not related to the availability of medical supplies (rho=-0.014; p=0.955). The evaluation by components showed that budget execution on medicines was positively related to the availability of supplies (rho=0.417; p=0.045), which was also valid in the segmented analysis only for hospitals (rho: 0.594; p=0.032). Although budget execution in segmented materials and supplies for hospitals was related to the availability of supplies, this relationship was inverse (rho=-0.552; p=0.043). Conclusions: The general budget execution of financial transfers from the SIS was not related to the availability of medical supplies, but the spending component on medicines was.

RESUMO
Objetivo: avaliar a precisão do controle do limite apical de instrumentação do motor endodôntico SENSORY, acionado em três velocidades de rotação (300, 600 e 900 RPM) e função de parada automática apical (Auto Apical Stop - AAS). Material e métodos: sessenta pré-molares inferiores humanos unirradiculados tiveram seus acessos realizados e diâmetro foraminal padronizado em 300 µm. Os dentes foram aleatoriamente divididos em três grupos (n=20) e tiveram seus canais preparados instrumento Logic 30/05, acionado na velocidade predefinida e função AAS ajustada para a marca 0,0. Os instrumentos foram medidos em paquímetro digital e o comprimento real do canal foi aferido pelo método visual direto sob magnificação. Resultados: os valores absolutos dos erros médios e de precisão (±0,5 mm), obtidos foram respectivamente: 0,21 mm e 95% (300 RPM), 0,26 mm e 95% (600 RPM), 0,20 mm e 95% (900 RPM). Não houve diferença significativa entre os grupos (P>0,05). Conclusão: nas condições deste estudo, o uso da função de parada automática forneceu um controle adequado e preciso do limite apical durante a modelagem endodôntica em todas as velocidades testadas.
Objective: to evaluate the accuracy of the control of the apical limit of instrumentation of the SENSORY endodontic motor, activated at three rotation speeds (300, 600 and 900 RPM) and apical automatic stop function (Auto Apical Stop - AAS). Material and methods: Sixty single-rooted human mandibular premolars had their access performed and the foraminal diameter was standardized at 300 µm. The teeth were randomly divided into three groups (n=20) and had their canals prepared with a Logic 30/05 instrument, activated at the predefined speed and the AAS function set to the 0.0 mark. The instruments were measured using a digital caliper and the actual canal length was measured using the direct visual method under magnification. Results: the absolute values of mean and precision errors (±0.5 mm) obtained were respectively: 0.21 mm and 95% (300 RPM), 0.26 mm and 95% (600 RPM), 0.20 mm and 95% (900 RPM). There was no significant difference between groups (P>0.05). Conclusion: Under the conditions of this study, the use of the automatic stop function provided adequate and accurate control of the apical limit during endodontic shaping at all speeds tested.

Dermatology is one of the medical fields outside the radiology service that uses image acquisition and analysis in its daily medical practice, mostly through digital dermoscopy imaging modality. The acquisition, transfer, and storage of dermatology images has become an important issue to resolve. We aimed to describe our experience in integrating dermoscopic images into PACS using DICOM as a guide for the health informatics and dermatology community. During 2022 we integrated the video dermoscopy equipment through a strategic plan with an 8-step procedure. We used the DICOM standard with Modality Worklist and Storage commitment. Three systems were involved (video dermoscopy software, the EHR, and PACS). We identified critical steps and faced many challenges, such as the lack of a final model of DICOM standard for dermatology images.

OBJECTIVES: This study aimed to evaluate cytogenetic damage in the buccal mucosa of non-exposed subjects (N = 33) and insecticide-exposed fumigators (N = 31) in the urban area of Cali, Colombia. MATERIAL AND METHODS: Through a questionnaire sociodemographic data, anthropometric measurements, state of health, and lifestyle were collected. Buccal micronucleus cytome (BMCyt) assay was using for evaluate cytogenetic damage. RESULTS: The study showed that all fumigators used adequate personal protective equipment (PPE) and had low alcohol consumption. The authors did not find significant differences in BMCyt biomarkers between the groups (p > 0.05). Multivariate analysis showed a 13% increase in micronucleus (MN) frequency for every year of increasing age (OR = 1.13, p = 0.029), and higher MN with the decrease in daily fruit consumption (OR = 4.71, p = 0.084), without statistical significance. CONCLUSIONS: The results between groups could be related to healthy habits and PPE use among the subjects. Int J Occup Med Environ Health. 2024;37(1):128-37.
