Cardiac complications are caused by an unbalanced diet, the consumption of alcohol, smoking tobacco, in addition to the excess of polluting gases such as carbon dioxide (CO2), among other gases that are harmful to the human body, due to these types of problems, they arise more frequently in people, which lead to heart problems at an early age. An optimal prevention of these cardiac abnormalities is necessary using an Electrocardiogram (ECG), by using this equipment it is possible to detect the cardiac anomalies that the person may have, thus giving early prevention for cardiac abnormalities that may be occurring in the patient. The design of a low-cost ECG will be considered using the AD8232 module, which allows recording the electrical activities of the heart, obtaining an ECG using the Arduino, in addition the Bluetooth module will send the data collected from the ECG from a patient to a cellphone which will store this information, to be later analyzed by a cardiologist. This paper is intended for use in health campaigns, given that according to the Pan American health organization, 70% of deaths in the world are due to heart problems, due to this figure, it is expected to reduce the rate with early prevention, which consists of the implementation of this biomedical equipment in health campaigns that will have the basic functionalities for the analysis of the electrocardiogram and that is low cost compared to biomedical equipment currently that provide the same functionalities.

The spread of COVID-19 has been taken on pandemic magnitudes and has already spread over 200 countries in a few months. In this time of emergency of COVID-19, especially when there is still a need to follow the precautions and developed vaccines are not available to all the developing countries in the first phase of vaccine distribution, the virus is spreading rapidly through direct and indirect contacts. The World Health Organization (WHO) provides the standard recommendations on preventing the spread of COVID-19 and the importance of face masks for protection from the virus. The excessive use of manual disinfection systems has also become a source of infection. That is why this research aims to design and develop a low-cost, rapid, scalable, and effective virus spread control and screening system to minimize the chances and risk of spread of COVID-19. We proposed an IoT-based Smart Screening and Disinfection Walkthrough Gate (SSDWG) for all public places entrance. The SSDWG is designed to do rapid screening, including temperature measuring using a contact-free sensor and storing the record of the suspected individual for further control and monitoring. Our proposed IoT-based screening system also implemented real-time deep learning models for face mask detection and classification. This module classified individuals who wear the face mask properly, improperly, and without a face mask using VGG-16, MobileNetV2, Inception v3, ResNet-50, and CNN using a transfer learning approach. We achieved the highest accuracy of 99.81% while using VGG-16 and the second highest accuracy of 99.6% using MobileNetV2 in the mask detection and classification module. We also implemented classification to classify the types of face masks worn by the individuals, either N-95 or surgical masks. We also compared the results of our proposed system with state-of-the-art methods, and we highly suggested that our system could be used to prevent the spread of local transmission and reduce the chances of human carriers of COVID-19.

Cardiac complications after subarachnoid hemorrhage (SAH) occur frequently, but their prognostic significance remains unclear. We performed a meta-analysis to assess whether echocardiographic wall motion abnormalities (WMA), electrocardiographic (ECG) changes, or elevated markers for myocardial damage are related to the occurrence of delayed cerebral ischemia (DCI) or death. Methods All articles that reported on cardiac abnormalities after aneurysmal SAH, that met predefined criteria, and were published between 1960 and 2007 were assessed. Data were extracted on predefined methodological criteria, patient characteristics, prevalence of cardiac abnormalities, and DCI or death. We calculated pooled relative risks (RR) with corresponding 95% confidence intervals (CI) for the separate cardiac abnormalities and outcome. Results We included 25 studies (16 prospective), comprising 2690 patients (mean age 53 years; 35% was male). The figure shows the univariable RRs of the determinants for death. For DCI we found a significant association with WMA (RR 2.10 [CI 1.17, 3.78]); Troponin RR 3.15 [CI 2.27, 4.38]; CK-MB RR: 2.90 [CI 1.86, 4.52]; BNP RR: 4.52 [CI 1.79, 11.39]; and ST depression RR: 2.40 [CI 1.2, 4.9]. No significant associations were found for DCI and ST elevation RR: 2.1 [CI 0.7, 5.7]; T wave abnormality RR: 0.9 [CI 0.5, 1.7]; U wave RR: 0.7 [CI 0.4, 1.3] or prolonged QT RR: 1.0 [CI 0.5, 2.3]. Conclusion Cardiac abnormalities increase the risk of DCI and death after SAH. Future research should be directed towards elucidating the multivariable relationship between the cardiac prognosticators, the pathophysiological mechanism and potential treatment options.

Abstract Tobacco use is one of the main public health concerns as it causes multiple diseases. The Democratic People’s Republic of Korea (DPRK) is one of the 168 signatory countries of the World Health Organization (WHO) member states agreed to adopt the WHO Framework Convention of Tobacco Control (FCTC). However, there is lack of information regarding the tobacco use in the DPRK and the government’s efforts for tobacco control. The aim of the study was to find the prevalence of tobacco use among the DPRK people and the government’s efforts to control tobacco use among its population, through literature review combined with online media content analysis. In 2020, the prevalence of tobacco smoking in males of 15 years and older was 46.1%, whereas that in females was zero. The online media contents showed the DPRK government’s stewardship to promote population health by controlling tobacco use. Furthermore, the DPRK government has taken steps to implement the mandates of the FCTC including introduction of new laws, promotion of research, development of cessation aids, as well as public health campaigns.

Objectives. The simulation of microlaryngeal skills is rarely seen in surgical training, but it is particularly important in phonomicrosurgery. This study described and validated the laryngeal surgical simulator through surgical training.Methods. A simple and low-cost simulator was developed for the fixation of the suspension laryngoscope and porcine larynges. Twenty participants with work skills and experience did preparation before training, and performed suture and carbon dioxide (CO2) laser cordectomy for simulator evaluation. The results were proposed by the aspects of time taken for each procedure, the global rating scale, a procedure-specific assessment, and a post-simulation questionnaire.Results. All participants completed the preparation within 9 minutes and reached the conclusion that the microlaryngeal surgical simulator was helpful in improving their surgical skills. The performance of experts was superior to that of novices in both suture and CO2 laser cordectomy.Conclusion. This simulator could be easily assembled and was successfully validated by microlaryngeal surgical training both subjectively and objectively. It may be helpful to clinicians in microlaryngeal skills.

Abstract A rapid, specific and sensible polystyrene latex-based reagent has been developed to detect rheumatoid factor (RF) in human sera. Detection of RF is one of the criteria for rheumatoid arthritis (RA) diagnosis. RF includes immunoglobulins IgG, IgM or IgA targeting human-IgG Fc region, found in sera of 70–90% of patients with RA. Spherical, clean polystyrene particles of 480±80 nm with a Z-potential of -28 mV were synthesized. Purified gamma-globulin human blood fraction, used as IgG source, was adsorbed on particles in glycine-buffered saline with a fivefold excess of the immunoglobulins needed to saturate the calculated total surface area of the particles. The reagent was calibrated against the World Health Organization international serum reference preparation and tested with commercial positive and negative RF controls. Reactivity of the developed diagnostic reagent with human sera, either positive or negative for RF, was evaluated. The sera were tested both intact and following complement inactivation. When complement-inactivated sera were used, our reagent showed 100% coincidence of results with a commercial diagnostic kit of specificity of 80% and sensibility of 93%. The in-house reagent developed in the present work is easy to prepare and at relatively low cost, making it ideal for RF detection in low-income settings.

Introduction: Most maternal deaths that occur in developing countries are considered unfair and can be avoided. In 2008, The World Health Organization (WHO) proposed a checklist for childbirth care, in order to assess whether a simple, low-cost intervention had an impact on maternal and neonatal mortality in low-income countries. Objective: To translate, adapt and validate the content of the WHO Safe Childbirth Checklist (SCC) for its use in Colombia Methods: The checklist was translated and adapted to the Colombian context. It was subsequently validated by a panel of experts composed of 17 health workers with experience in maternal and neonatal care and safety. Reliability among judges was estimated (Rwg) and items were modified or added to each section of the list according to the results. Results: Modifications were made to 28 items, while 19 new items were added, and none was removed. The most important modifications were made to the management guidelines included in each item, and the items added refer to risks inherent to our environment. Conclusion: The Colombian version of the SCC will be a useful tool to improve maternal and neonatal care and thereby contribute to reducing maternal and neonatal morbidity and mortality in our country.

The exhaust plume capture method is a commonly used approach to measure pollutants emitted by in-use heavy-duty diesel trucks. Lower cost sensors, if used in place of traditional research-grade analyzers, could enable wider application of this method, including use as a monitoring tool to identify high-emitting trucks that may warrant inspection and maintenance. However, low-cost sensors have for the most part only been evaluated under ambient conditions as opposed to source-influenced environments with rapidly changing pollutant concentrations. This study compared black carbon (BC) emission factors determined using different BC and carbon dioxide (CO2) sensors that range in cost from $200 to $20,000. Controlled laboratory experiments show that traditional zero and span steady-state calibration checks are not robust indicators of sensor performance when sampling short duration concentration peaks. Fleet BC emission factor distributions measured at two locations at the Port of Oakland in California with 16 BC/CO2 sensor pairs were similar, but unique sensor pairs identified different high-emitting trucks. At one location, the low-cost PP Systems SBA-5 agreed on the classification of 90% of the high emitters identified by the LI-COR LI-7000 when both were paired with the Magee Scientific AE33. Conversely, lower cost BC sensors when paired with the LI-7000 misclassified more than 50% of high emitters when compared to the AE33/LI-7000. Confidence in emission factor quantification and high-emitter identification improves with larger integrated peak areas of CO2 and especially BC. This work highlights that sensor evaluation should be conducted under application-specific conditions, whether that be for ambient air monitoring or source characterization.

This paper introduces an efficient and robust method for heartbeat detection based on the calculated angles between the successive samples of electrocardiogram (ECG) signal. The proposed approach involves three stages: filtering, computing the angles of the signal and thresholding. The suggested method is applied to two different types of ECG databases (QTDB and MIT-BIH). The results were compared with the other algorithms suggested in previous works. The proposed approach outperformed the other algorithms, in spite of its simplicity and their fast calculations. These features make it applicable in real-time ECG diagnostics systems. The suggested method was implemented in real-time using a low cost ECG acquisition system and it shows excellent performance.

Quick on-scene assessment and early intervention is the key to reduce the mortality of stroke and trauma patients, and it is highly desirable to develop ambulance-based diagnostic and monitoring devices in order to provide additional support to the medical personnel. We developed a compact and low cost ultra wideband noise sensor for medical diagnostics and vital sign monitoring in pre-hospital settings. In this work, we demonstrated the functionality of the sensor for respiration and heartbeat monitoring. In the test, metronome was used to manipulate the breathing pattern and the heartbeat rate reference was obtained with a commercial electrocardiogram (ECG) device. With seventeen tests performed for respiration rate detection, sixteen of them were successfully detected. The results also show that it is possible to detect the heartbeat rate accurately with the developed sensor.

Abstract A number of resources, every year, being spent to tackle early detection of cardiac abnormalities which is one of the leading causes of deaths all over the Globe. The challenges for healthcare systems includes early detection, portability and mobility of patients. This paper presents a categorical review of smartphone-based systems that can detect cardiac abnormalities by the analysis of Electrocardiogram (ECG) and Photoplethysmography (PPG) and the limitation and challenges of these system. The ECG based systems can monitor, record and forward signals for analysis and an alarm can be triggered in case of abnormality, however the limitation of smart phone’s processing capabilities, lack of storage and speed of network are major challenges. The systems based on PPG signals are non-invasive and provides mobility and portability. This study aims to critically review the existing systems, their limitation, challenges and possible improvements to serve as a reference for researchers and developers.
