Background: The COVID-19 crisis is fuelling a state of fear among the human population at global level. Especially, those living in informal settlements and slums worldwide have been profoundly impacted by this pandemic. Individuals living in these places are already leading underprivileged lives. Thus, the economic and mental health problems caused by the COVID-19 crisis have further exacerbated their living standards, which has resulted, for instance, in tragedies such as suicides. Objective: In this study, we have sought to identify those individuals most at risk of displaying high levels of fear of COVID-19 in an informal settlement located in the capital city of Peru. Methods: A questionnaire was administered to 449 inhabitants living in the Carmen Alto informal settlement. The questionnaire was made up of two parts: the first one inquired about demographic data and the second part consisted of the Fear of COVID-19 Scale. Results: The demographic variables of age, gender, marital status, educational level, occupation, whether a relative from the household was infected with COVID-19, and whether one of them died of this showed significant differences. It could be observed as well that the groups of females, stable workers, unemployed and those having completed a workforce education are at higher odds of displaying high levels of fear of COVID-19. As expected, the groups that had either a relative infected with COVID-19 or a relative death by this had the highest levels of fear towards the virus. Conclusion: The female participants are more likely to display higher levels of fear of COVID-19 due to the terrible effect that unfavorable events have on them. In the cases of the unemployed and stable workers, their proneness to show high levels of fear towards the virus is because they have lost their incomes, due to the loss of their jobs, and because of fear of infection, respectively. Hence, we hope that this work serves Peruvian (and other) health authorities to develop strategies that help individuals living in informal settlements and are in urgent need of mitigating mental health problems.

Now-a-days, it is no surprise that mobile devices have become a very useful tool in the daily tasks of many people worldwide. This is thanks to their various features such as portability, connectivity, entertainment, work tool, etc. However, due to the bad posture that users have when using them, a syndrome called "Text Neck" is produced. This is caused by prolonged use of the devices looking down and tilting the head at different angles. The degree of inclination of the head causes a detrimental effect on the neck joints, so that the greater the degree of inclination the effect of the weight of the head on the neck increases detrimentally. However, currently mobile devices have sensors that help in monitoring the activities of users, in this sense, there is the gyroscope that allows the completion of the position and the accelerometer that tells us the amount of movement of the device. In this sense, a mobile application has been developed that by monitoring the information of the angle of inclination of the device and the time it remains in the same, allows notifying users to adopt a proper position. The aim is to reduce the number of people affected by text neck syndrome.

The objective of this study is to determine family functionality and resilience in adolescents from a vulnerable educational institution in Lima. It is a quantitative, descriptive, correlational study, with a population of 571 adolescents who answered a questionnaire of sociodemographic data, and the family APGAR scales and Connor Davidson Resilience Scale (CD-RISC) that will allow observing family functionality and resilience. In the results, we observe that in adolescents with severe family dysfunction, 157 (51.8%) have low resilience, in moderate family dysfunction, 155 (100%) have medium resilience, in mild family dysfunction, 5 (100%) have high resilience and with good family function, 108 (100%) have high resilience. Therefore, it is concluded that the family should be intervened to identify possible risk factors that harm the adolescent in the development of their capacities.

COVID-19 is a disease that directly affects the respiratory tract, being harmful in asthmatic patients because this condition causes a lack of oxygen, even to the extent that it requires external equipment to combat drowning. Likewise, it highlights the importance of maintaining a treatment or therapy correctly to prevent your disease from worsening or being exposed to other diseases, putting your health at risk. The diseases that asthmatic patients can acquire can result from pathologies, which have been growing over the years due to lack of equipment or efficient examinations that generate complete information about respiratory conditions about asthmatic patients, therefore, by developing an advanced system, the chances of detecting pathologies prematurely increase considerably,  which is an essential tool today. According to the problem exposed, in this research an automatic system of detection of pathologies in the respiratory system was carried out for the care of the patient with bronchial asthma visualized by computerized radiography, so that any pathology can be detected by means of a premature diagnosis in the respiratory system and the doctor can perform a correct treatment on the asthmatic patient. Through the tests carried out by the system, its performance was accurate and efficient, being suitable to be implemented in various hospitals so that the doctor can treat the disease in time, since the system presented a 98.79% efficiency in the detection of pathologies.
