Published: January 2020

Hearing loss is one of the most common health problems today, it can appear at any age and the causes are varied, in order to prevent it or adapt to the changes brought about by the hearing impairment, it is necessary to diagnose it in time. The technology in terms of applications for health care smartphones has constantly evolved, so that today play an important role and are among the most downloaded from application stores, several of these applications are the diagnosis of hearing loss and use the method of pure tones. In this study a Systematic Mapping of Literature SMS (Systematic Mapping Study) is made to look for mobile applications that use other diagnostic methods that offer similar or better results, of the 13 applications found, 11 used the method of pure tones and in only 2 of them was implemented the speech audiometry (word recognition), concludes that diagnostic hearing loss tests based on mobile applications are reliable alternatives to conventional audiometric systems, and that pure tone thresholds alone are an incomplete assessment of hearing, and there is a need to develop new hearing measurement methods and combine them with other methods to complement the diagnosis.
Resumen: La pérdida de la audición es uno de los problemas de salud más comunes en la actualidad, puede aparecer a cualquier edad y las causas son variadas, para poder prevenirla o adaptarse a los cambios que conlleva la deficiencia auditiva, es necesario diagnosticarla a tiempo. La tecnología en cuanto a aplicaciones para smartphones de asistencia de salud ha evolucionado constantemente, tal es así que hoy en día juegan un papel importante y son de las más descargadas de las tiendas de aplicaciones, varias de esas aplicaciones son las de diagnóstico de pérdida auditiva y utilizan el método de los tonos puros. En este estudio se hace un Mapeo Sistemático de Literatura SMS (Systematic Mapping Study) para buscar aplicaciones móviles que utilicen otros métodos de diagnóstico que ofrezcan similares o mejores resultados, de las 13 aplicaciones encontradas, 11 utilizaron el método de los tonos puros y en solo 2 de ellas se implementó la logoaudiometria (reconocimiento de palabras), por lo que se concluye que las pruebas de diagnóstico de pérdida auditiva basadas en aplicaciones móviles, son alternativas confiables a los sistemas de audiometría convencionales, y que los umbrales de tonos puros por sí solos son una evaluación incompleta de la audición, y existe la necesidad de desarrollar nuevos métodos de medición de audición y combinarlos con otros métodos para complementar el diagnóstico.

This paper presents an application to solve the problem of low efficiency in the generation of academic schedules for an educational institution through metaheuristic techniques. The agile SCRUM methodology was used for the planning and development of the system, in addition a sample of four processes for the evaluation of system efficiency was determined. In the planning phase, 15 user stories, 13 technical stories and 19 system sprints were identified. In the development phase the design of the architecture, interfaces, database was carried out. The process for working the genetic algorithms in the generation of schedules through the processes of initialization, selection, crossing, mutation and recombination was carried out until compliance with an objective function thus obtaining an academic schedule with the conditions that the educational institution requires. To evaluate the efficiency of the system, the ISO/ IEC 25010 standard was used through the sub-characteristics of time behavior and resource utilization. The results obtained in time behavior reveal that with the use of the system it is reduced by 99.12%, compared to the manual processes thus showing a total efficiency of 93.75%.

Aim.We aimed to study in real clinical practice the clinical and anamnestic characteristics, the peculiarities of double antiplatelet therapy (DAPT) prescription as well the incidence of ischemic and hemorrhagic events in patients with ST-elevated myocardial infarction (MI) during a year of follow-up, taking into account the baseline PRECISE-DAPT scores.Material and methods.The study included 680 patients with MI from the database of Kemerovo observational registry for acute coronary syndrome (ACS). All the patients retrospectively underwent an individual calculation using the PRECISE-DAPT score. Then, depending on the number of the points, all the patients were divided into the low (less than 25 points) and high (25 or more points) risks groups. Differences in clinical and anamnestic parameters, the peculiarities of DAPT prescription, as well as the incidence of ischemic and hemorrhagic outcomes during a year of follow-up after MI were estimated in the groups.Results.The Russian patients with ST-elevated MI and the high PRECISE-DAPT hemorrhagic risk score had a history of renal pathology (р=0.010), multivessel coronary artery disease and polyvascular disease (р=0.002), prior angina pectoris (р=0.001), as well as the course of the index event with the manifestations of acute coronary failure (р=0.001) more often than the patients from the low-risk group. The patients of the high-risk group less often underwent coronary angiography with stenting (р=0.001), as well as coronary artery bypass grafting (р=0.010) at hospitalization and had a higher in-hospital mortality rate (р=0.002). The patients at high hemorrhagic risk according to the PRECISE-DAPT score were less often prescribed with DAPT within a year after MI (р=0.001) and aspirin monotherapy was preferred more often (р=0.001). At the same time, the patients at high hemorrhagic risk on the PRECISE-DAPT score had more often major bleedings, recurrent MI and deaths (р=0.001) within a year after MI.Conclusion.In the present study, the possibilities of risk assessment with the PRECISE-DAPT score were retrospectively tested on the sample of patients with MI from the ACS registry in Kemerovo city. Good identification of patients with the high risks of hemorrhagic events and ischemic outcomes within 12 months of the follow-up after index MI has been shown, which allows to recommend the PRECISE-DAPT score for a clinical practice in order to rationalize the approaches to DAPT prescription and to optimize the existing approaches to the comprehensive risk assessment of patients with ACS along with existing scales.

Se presenta un listado preliminar de la herpetofauna de los municipios de Tumaco y Francisco Pizarro, departamento de Nariño, Colombia, ubicados al sur del Chocó biogeográfico, basado en datos de campo y búsquedas en base de datos y literatura. Registramos 25 especies de anfibios y 55 de reptiles, siendo las familias Hylidae y Craugastoridae (anfibios) y las familias Colubridae y Dactyloidae (reptiles) las de mayor riqueza, patrón similar al observado a escala global. Se reportan dos nuevos registros de especies para Colombia (Pristimantis walkeri y Scinax tsachila), así como extensiones de distribución geográfica (Allobates talamancae, Anolis auratus, Dendropsophus ebraccatus, Gonatodes albogularis y Scinax sugillatus). Las curvas de acumulación de especies y la cobertura de muestreo revelan que se necesitan más estudios de campo para complementar esta lista, especialmente los estudios que utilizan metodologías enfocadas en especies acuáticas y fosoriales, y que podría haber un efecto de la deforestación en la diversidad de la herpetofauna, lo cual concuerda con la falta de anfibios de dosel y la presencia exclusiva de especies asociadas a la hojarasca o al interior del bosque en las localidades con mejor cobertura vegetal.

Abstract
Background:Adults with chronic conditions such as heart disease, diabetes, or lung disease are more likely to develop complications from a number of vaccine-preventable diseases, including influenza and pneumonia. In this study, we use the data from a chronic disease management information system in Shanghai to estimate vaccination coverage and characterize predictors of seasonal influenza and 23-valent pneumococcal polysaccharide vaccine (PPSV23) vaccination among people with chronic disease in Shanghai.
Methods:The Shanghai Centers for Disease Control and Prevention have information systems related to chronic disease management, hospital records, and immunizations. Data from individuals with hypertension, diabetes and chronic obstructive pulmonary disease (COPD) were abstracted during July 2017. The main outcome was coverage of pneumococcal and influenza vaccination. Vaccination coverage was calculated across demographic groups. Significance in bivariate associations was assessed through Pearson’s chi-square tests, and in multivariable models through logistic regression models with a forward stepwise method to select variables.
Results:In the sample of 2,531,227 individuals ≥15 years, 22.8% were vaccinated for pneumonia from January 2013 to July 2017, and the vaccination coverage of influenza in the 2016/17 influenza season was 0.4%. Vaccination coverage was highest in those 70-79 and lowest in those younger than 60. Compared to urban areas, uptake in rural areas was higher for pneumonia vaccination (OR: 2.43, 95% CI: 2.41, 2.45), but lower for influenza vaccination (OR: 0.55, 95% CI: 0.51, 0.59). Having a greater number of chronic diseases was associated with higher likelihood of pneumonia vaccination (3 vs 1: OR: 1.68, 95% CI: 1.64, 1.71), but this relationship was not statistically significant for influenza vaccination.
Conclusions:We found low levels with of pneumococcal vaccination, and extremely low uptake of influenza vaccination among individuals with high risk conditions in Shanghai who should be priority groups targeted for vaccination. Interventions could be designed to target groups with low uptake – like younger adults, and individuals who have not yet retired.

Published: January 2020

Abstract
Background: Postoperative pain is a common disorder that interferes with the quality of sleep after nasal endoscopic surgery and delays postoperative recovery. Acupuncture is an effective tool for pain management. However, electroacupuncture specifically for the relief of postoperative pain after nasal endoscopic surgery has not yet been studied through a randomized controlled trial. Method/Design: A pilotrandomized, sham-controlled, patient- and- assessor-blind trial is designed to evaluate the efficacy and safety of electroacupuncturein managing postoperative pain following nasal endoscopic surgery of sinusitis with nasal polyps. There will be 30participants randomly allocated to an electroacupuncture or non-invasive sham control in a 1:1 ratio. Treatment will be done within 2 hours before operation, immediately after the operation upon arrival to the recovery ward, and once daily for 3 days. The primary outcome of the Pain Numerical Rating Scale (NRS) will be analyzed using the area-under-the-curve (AUC) method. The secondary outcome measures include Heart Rate (HR) and Blood Pressure (BP) after operation, the sleep quality during the hospital stay (Actigragh),Quality of Recovery-15 (QoR-15), and the MOS item short form health survey (SF-36). ITT analysis will be used in this RCT. Discussion: This pilot randomized controlled trial will explore the feasibility of further clinical application for the management of postoperative pain using electroacupuncture treatment, and it will inform the design of a further full-scale trial.

Abstract
BACKGROUND: Fall-related injuries are important public health problem worldwide. We aimed to describe the epidemiological and clinical characteristics of fall-related injuries in a level 1 trauma center.
METHOD: A retrospective analysis of Qatar Trauma Registry data was conducted on patients admitted for fall-related injuries between 2010 and 2017. Comparative analyses of data by gender, age-groups and height of falls were performed to describe the epidemiological and clinical characteristics of patients, and in-hospital outcomes.
RESULTS:
A total of 4040 patients with fall-related injuries were identified in the study duration which corresponds to the rate of 2.34 per 10,000 population in Qatar. Although the rate of fall injuries decreased over the years, the average number of patients per year still accounts for 32% of the moderate and severe injuries requiring admission. Most of the injuries were to the head (36%) followed by spines (29%) and chest (23%). Males were predominant (89%), more likely to fall at workplace, fall from a greater height and experience polytrauma than females. Working age-group (20-59 years) were the major victims (73%), more likely to fall at work place, fall from height comparing to older adults who tend to fall at home, fall from the same level. Overall in-hospital mortality was 3%. Outcomes including longer length of hospital stay and mortality were generally associated with the height of falls.CONCLUSION: Fall-related injuries remain as a significant burden in trauma center. Variations in pattern of injuries by age, gender and height of fall provide important information for targeted preventive measures

Abstract
Objective This study examined whether exposure to smoking and vaping cues the urge to smoke or vape. It extends previous studies on first-generation cigalikes (visually similar to cigarettes) and second-generation devices (visually similar to pens) by including third-generation tank system devices (larger bulky units). In an online experiment, participants were randomly assigned to view one of four videos, which included smoking, vaping (cigalike or tank system), or neutral cues. The primary outcome was urge to smoke. Secondary outcomes were urge to vape, desire to smoke and vape, and intention to quit or remain abstinent from smoking.Results UK adults varying in smoking (current or former) and vaping (user or non-user) status (n=1120) completed the study: 184 (16%) failed study attention checks meaning 936 were included in the final analysis. Urges to smoke were similar across cue groups. Urges to vape were higher following exposure to vaping compared to neutral cues. There was no clear evidence of an interaction between cue group and smoking or vaping status. The lack of cueing effects on smoking urges is inconsistent with previous research, raising questions about the ability to assess craving in online settings.
Effect of a tailored leaflet to promote diabetic retinopathy screening among young adults with type 2 diabetes: a randomised controlled trial.

Abstract
Background: Young adults with type 2 diabetes (aged 18-39 years) are at risk of early onset and rapid progression of diabetic retinopathy, the leading cause of blindness and vision loss in working age adults. Early detection via retinal screening can prevent most vision loss, yet screening rates are consistently lower among this priority population than the general diabetes population. We aimed to test the effect of a tailored, evidence-based brief health behaviour change intervention (leaflet) on self-reported screening uptake, and previously identified social cognitive determinants of retinal screening.
Methods: A pragmatic, two-arm randomised controlled trial was conducted from September 2014 to April 2015. Participants were stratified by prior screening uptake (Yes/No) and randomly allocated to intervention (leaflet) or ‘usual care’ control (no leaflet). Primary outcome was self-reported screening uptake four weeks post-intervention for ‘No’ participants who had not previously screened for diabetic retinopathy. Secondary outcome variables were changes in knowledge, attitudes, normative beliefs, intention and behavioural skills for all participants, irrespective of prior screening behaviour. To assess intervention effects on secondary outcome variables, we conducted independent samples t-tests (two-tailed) on pre-post change scores.
Results: 129 young adults (26% no prior retinal screen) completed baseline; 101 completed post-intervention. Power to determine effect on the primary outcome was curtailed by low recruitment of individuals with no prior retinal screen and loss to follow-up. Attrition was associated significantly with country of birth, language spoken at home, and marital status. Significant intervention effect was observed for one secondary outcome variable: knowledge of diabetic retinopathy (p=.03) with moderate effect (partial eta squared h2=.05); no adverse effects were reported. Control group participants received the leaflet at study completion.
Conclusions: This study confirms that a well-designed eye health and retinal screening promotion leaflet can increase knowledge of diabetic retinopathy, an important screening predictor. The study highlights the challenges of conducting ‘real-world’ health behaviour change research with this priority population, providing insights for clinicians and researchers. Strategies to recruit, engage and retain hard-to-reach populations are discussed including nonconventional alternatives to randomised controlled trial designs.
