Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ2＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P 2 (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Accuracy of Working Length Determination - Electronic Apex Locator Versus Cone Beam Computed Tomography

ABSTRACT Objective: To compare the accuracy of working length determination between cone beam computed tomography (CBCT) and electronic apex locator by measuring the actual working length of teeth. Material and Methods: A total of 150 single-rooted tooth assessed by radiograph undergoing root canal therapy were selected. The process was repeated to obtain a buccolingual and mesiodistal section of all teeth. The measurement line was considered from the reference occlusal plane following the center of the canal to the terminus. All information regarding the accuracy of cone-beam computed tomography and apex locator was noted in a pre-designed proforma. Results: CBCT consistently demonstrated high accuracy across all tooth types in both jaws. The electronic apex locator exhibited varying precision, with greater accuracy observed in the mandible. Statistical analyses revealed significant differences in electronic apex locator accuracy among tooth types in the maxilla (p=0.042), emphasizing the importance of specific clinical considerations. Conclusion: Cone beam computed tomography emerges as a reliable diagnostic tool for accurate working length determination, especially in complex cases, while the electronic apex locator remains valuable with careful consideration of potential variations in accuracy. An individualized approach, considering tooth type, jaw location, and clinical context, is crucial for precise working length determination in endodontic practice.

Financial Impact of Deep Sternal Wound Infections After Coronary Surgery: A Microcosting Analysis

ABSTRACT Introduction: Deep sternal wound infections (DSWI) are so serious and costly that hospital services continue to strive to control and prevent these outcomes. Microcosting is the more accurate approach in economic healthcare evaluation, but there are no studies in this field applying this method to compare DSWI after isolated coronary artery bypass grafting (CABG). This study aims to evaluate the incremental risk-adjusted costs of DSWI on isolated CABG. Methods: This is a retrospective, single-center observational cohort study with a propensity score matching for infected and non-infected patients to compare incremental risk-adjusted costs between groups. Data to homogeneity sample was obtained from a multicentric database, REPLICCAR II, and additional sources of information about costs were achieved with the electronic hospital system (Si3). Inflation variation and dollar quotation in the study period were corrected using the General Market Price Index. Groups were compared using analysis of variance, and multiple linear regression was performed to evaluate the cost drivers related to the event. Results: As expected, infections were costly; deep infection increased the costs by 152% and mediastinitis by 188%. Groups differed among hospital stay, exams, medications, and multidisciplinary labor, and hospital stay costs were the most critical cost driver. Conclusion: In summary, our results demonstrate the incremental costs of a detailed microcosting evaluation of infections on CABG patients in São Paulo, Brazil. Hospital stay was an important cost driver identified, demonstrating the importance of evaluating patients' characteristics and managing risks for a faster, safer, and more effective discharge.

Coronary Artery Bypass Grafting: A Comparative Exercise between Patients from the BYPASS Registry and Patients from a University Hospital

ABSTRACT Introduction: The coronary artery bypass grafting (CABG) data provided by the Brazilian Registry of Cardiovascular Surgeries in Adults (BYPASS) Registry is a Brazilian reality. Objective: To carry out a comparative exercise between the BYPASS Registry published data and data from patients operated on in a randomly chosen period (2013-2015) at Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP-USP). Methods: This is a retrospective study reviewing 173 electronic medical records of CABG patients from the HCFMRP-USP. These data were compared with the BYPASS Registry published data. Chi-square test was used to verify the changes within the prevalence of adequate/inadequate biochemical tests before and after surgery. The sample was divided into groups consistent with cardiopulmonary bypass (CPB) time (CPB ≤ 120 minutes and CPB > 120 minutes). For the complications, prevalence by the chi-square test was adopted. Significant P-values are < 0.05. Results: The comparative operative data of the BYPASS Registry and the HCFMRP-USP patients were quite similar, except for the isolate use of only arterial grafts, which was more frequent on HCFMRP-USP patients (30.8% vs. 15.9%), and the use of radial artery, also more frequent on HCFMRP-USP patients (48.8% vs. 1.1%) Conclusion: The comparative study suggested that the BYPASS Registry should be a reference for CABG quality control.

Monocyte/High-Density Lipoprotein Ratio Is Associated with Atrial High-Rate Episodes within One Year Detected by Cardiac Implantable Electronic Devices

ABSTRACT Objective: To investigate the risk factors for predicting atrial high-rate episodes (AHREs) detected by cardiac implantable electronic devices (CIEDs). Methods: A total of 140 patients with CIED in our hospital from June 2013 to June 2018 were included and were followed up to observe whether they had AHREs. AHRE are defined as atrial rate ≥ 175 times/minute, lasting > 5 minutes, and reviewed by an experienced electrophysiologist with unclear clinical diagnosis. The patients fasted for 12 hours after implantation, and blood samples were collected for biochemical, lipid, and whole blood count detection. Follow-up was regular after discharge to record follow-up data of each patient and conduct statistical analysis. Results: One hundred and forty patients were implanted with dual-chamber pacemakers, their median age was 70 years old, 44.29% were male, 27 patients had AHRE within one year, and AHRE incidence rate was 19.29%. The microcytic to hypochromic (M/H) ratio was calculated for all AHRE patients and compared with the patients without AHRE; the M/H value of AHRE patients was significantly higher. Throughout the entire follow-up period, a total of 44 patients developed AHRE; when adjusted by multivariate analysis, only M/H ratio ≥ 4.5 vs. < 4.5 had statistical significance, and the adjusted hazard ratio value was 4.313 (1.675-11.105). Conclusion: As an indicator, M/H ratio may play an important role in the occurrence and development of atrial fibrillation and can be used as a predictor of AHRE in patients with CIED.

Smart phones for medical undergraduates: friend or foe?

Background: Smart phones are truly a boon for us in all aspects of our life. It helps mankind to lead a faster and easier life, but the same devices used to get things done are now the gatekeepers of an infinite number of distractions and sources of instant gratification. Even though, there is an ocean full of information a click away, we fail to utilize it for something resourceful. Increased media consumption, multi screening and social media usage reduce the ability to focus on tasks and duties which have a much higher priority.Methods: A cross sectional study was conducted with a validated questionnaire among 200 undergraduate MBBS students of a deemed to be medical university.Results: Among the ninety-eight per cent of the students who own a smartphone, all have access to the internet. Seventy-seven per cent of the students use these gadgets on a very regular basis throughout the day and among them only forty-six per cent were found to be using it for academic purposes.Conclusions: Through this study, it has become more discernible that smart phones have paved its way for a reckless future, though if used wisely it would become a blessing in disguise. The ever-changing medical fraternity could really benefit from this discovery but alas, a tool made to make our lives easier is weighing us down with its addictive and time-consuming features.

Residuos de celulares y tabletas: incidencia del nivel de escolaridad en las actitudes y percepciones frente a su manejo / Residues of cell phones and tablets: incidence of the school level in the attitudes and perceptions in front of its handling

RESUMEN El avance tecnológico ha traído consigo la generación de residuos de celulares y tabletas. Esta tendencia seguirá en aumento, dado el fácil acceso a estos dispositivos. En el siguiente estudio, se relaciona la incidencia del nivel de escolaridad, sobre las actitudes y las percepciones, que se tienen sobre el manejo de los residuos provenientes de celulares y de tabletas, con el fin de ahondar en esta problemática y aportar insumos para la creación de estrategias y de políticas encaminadas al desarrollo sustentable. Para esto, se aplicó una encuesta a 450 personas que habitan en la ciudad de Florencia - Caquetá, Colombia. Se realizó un test de independencia, que permitió decidir si el nivel de escolaridad incide sobre las actitudes y las percepciones. Los resultados obtenidos indicaron que no existe tal dependencia con las actitudes, pero sí con las percepciones, lo que demuestra la inconsistencia del ser humano entre lo que piensa y cómo actúa. Un hallazgo relevante en el presente estudio es que, en su gran mayoría, estos dispositivos o sus partes, después de un tiempo, terminan en la basura, junto con los residuos convencionales.

SUMMARY The technological advance has brought with it the generation of cell and tablet waste. This trend will continue to increase, given the easy access to these devices. In the following study, the incidence of schooling level is related to attitudes and perceptions about the handling of cell and tablet waste, in order to deepen this problem and provide inputs for the creation of strategies and policies aimed at sustainable development. For this, a survey was applied to 450 people living in the city of Florencia Caquetá Colombia. An independence test was carried out, which allowed to decide if the level of schooling affects attitudes and perceptions. The results obtained indicated that there is no such dependence on attitudes, but with perceptions, this shows the human being's lack of balance between what he thinks and how he acts. A relevant finding in the present study, is that the vast majority of these devices or their parts, after a while end up in the trash, along with conventional waste.

Impacto negativo de los medios tecnológicos en el neurodesarrollo infantil / Negative impact of technological media on child neurodevelopment

Resumen La exposición y el uso de medios electrónicos por parte de la mayoría de los niños es una realidad desde los primeros años de vida. Esta realidad se ha instalado en la vida de nuestros niños y de nuestra sociedad antes de que investigaciones cientí cas hayan podido evaluar su real impacto en el neurodesarrollo infantil. En los lactantes y pre-escolares, la exposición a pantallas electrónicas se ha asociado a un menor nivel de desarrollo cognitivo y del lenguaje. Asimismo, a mediano plazo, se ha relacionado con mayor riesgo de sobrepeso, dé cit de atención, y el riesgo de adoptar una actitud pasiva frente al mundo. En la edad escolar y en la adolescencia, el uso de estos instrumentos tecnológicos puede brindar oportunidades positivas para los aprendizajes y para la socialización. Sin embargo, más frecuentemente se observa un uso excesivo de estos dispositivos electrónicos, que repercute sobre la capacidad de concentración, el rendimiento escolar y sobre la cantidad y calidad del sueño nocturno. Algunos adolescentes que utilizan demasiado las redes sociales presentan síntomas de depresión, de déficit de sueño, sobrepeso, aislamiento social (afectados por el ciber-bullying), o están expuestos a contenidos y contactos inapropiados o riesgosos, y comprometen su privacidad y la con dencialidad de sus datos personales. Por todo ello, la comunidad académica debe informar sobre estos serios riesgos a la población, al mismo tiempo que continúa desarrollando investigaciones para conocer mejor el impacto que tienen los diferentes medios electrónicos sobre el neurodesarrollo y el bienestar de los niños y adolescentes.

Abstract Exposure and use of electronic media by the majority of children is part of their reality since the first years of life. This reality has installed in the life of our kids and our society before scientific research has been able to assess their real impact in child neurodevelopment. In infants, toddlers and preschoolers, exposure to electronic screens has been related to cognitive and language delay. Additionally, in the medium term, it has been related to a greater risk of overweight, lack of concentration and attention deficit, and a greater risk to adopt a passive attitude. In school age and in adolescence, these technological devices may bring positive opportunities towards learning and socialization. Nevertheless, more frequently, an overuse of these technologies is being seen, that affect the attention ability, the school performance and the amount and quality of nocturnal sleep of children and adolescents. Some adolescents that overuse social media develop symptoms of depression, insuffcient sleep, overweight and social isolation (affected by cyber-bullying) or are exposed to inappropriate or risky contents and contacts, and they endanger their privacy and the confidentiality of their personal data. For all these reasons, academic community has to inform the society about these serious risks, at the same time that continues developing researches to assess more profoundly the impact of the different electronic media to the neurodevelopment and well-being of our children and adolescents.

Comparison of sleep quality based on direction of shift rotation in electronics workers

BACKGROUND: Previous studies have reported the effects of direction of shift rotation on sleep, however, the findings are inconsistent. In this study, we investigated sleep quality related to direction of shift rotation using large-scale data from shiftwork-specific health examinations of electronics workers. METHODS: This study included 4750 electronics workers working in a rotating 3-shift system who completed a medical examination for shift workers survey from January 1 to December 31, 2014, at a general hospital. The subjects were categorized into one of two groups according to direction of shift rotation. We compared sleep quality index between the subjects who worked in forward rotation and backward rotation systems. RESULTS: Backward rotation was positively associated with prevalence of poor sleep quality. In the multivariable-adjusted model, when comparing backward rotation to forward rotation, the odds ratio (OR) with 95 % confidence interval (95 % CI) for poor sleep quality was 1.95 (1.58–2.41). After stratifying by gender, the ORs (95 % CIs) for poor sleep quality in male and female was 1.92 (1.47–2.49) and 2.13 (1.47–3.08), respectively. In subgroup analyses, backward rotation was significantly associated with poor sleep quality in workers ≥30 years of age compared with workers <30 years of age (adjusted OR 2.60 vs. 1.89, respectively; P for interaction <0.001). CONCLUSIONS: Our study supports that a backward rotation system is associated with poor sleep quality. Forward rotation systems should be considered to reduce sleep problems.

Breakthroughs are also needed in large-scale energy storage technologies. To seamlessly integrate renewable resources in the grid research and development must address challenges that high penetration levels will have in power system planning and operation, and in grid connection. Finally, the existing workforce and the students going into power and energy engineering careers need to be educated so that they can envision and develop the new approaches and technologies to maintain grid reliability and economy. The challenges of integrating high penetrations of renewable energy technologies into the grid are less well recognized in part because they require interdisciplinary research in such areas as power systems analysis, communications, power electronics, economics, operations research, and industrial organization.
