Furthermore, this study aims to raise awareness and provide a deeper insight into current scientific discussions.
  During the COVID-19 pandemic, special education schools for children in most areas of China were closed between the end of January and the beginning of June in 2020. The sudden interruption in schooling and the pandemic itself caused parents to be anxious and even to panic. Mobile-based parenting skills education has been demonstrated to be an effective method for improving the psychological well-being of mothers with children with autism. However, whether it can improve the psychological states of mothers in the context of the COVID-19 pandemic is a subject that should be urgently investigated.
 
  The aim of this study is to evaluate the efficacy of WeChat-based parenting training on anxiety, depression, parenting stress, and hope in mothers with children with autism, as well as the feasibility of the program during the COVID-19 pandemic.
 
  This was a quasi-experimental trial. A total of 125 mothers with preschool children with autism were recruited in January 2020. The participants were assigned to the conrogress more than 80% of the time for all 20 weeks.
 
  The WeChat-based parenting training is acceptable and appears to be an effective approach for reducing anxiety, depression, and parenting stress, as well as increasing hope in mothers with children with autism during the global COVID-19 pandemic. Future studies with rigorous designs and longer follow-up periods are needed to further detect the effectiveness of the WeChat-based parenting training.

  The majority of adolescents own smartphones, although only 8% of them use health apps. Attrition rates from adolescent mobile health (mHealth) interventions for treating mental health problems such as anxiety and depression are an issue with a high degree of variation. Attrition in mHealth interventions targeting adolescent populations is frequently presented in a two-point fashion, from initiation of the intervention to the end of treatment, lacking more time-specific information on usage and times of attrition. Self-efficacy could provide an avenue to lower attrition rates, although a better understanding of the relationship between mental health factors and time-specific attrition rates is needed.
 
  The aims of this study were to obtain time-specific attrition rates among adolescents in an mHealth intervention, and to describe the intervention's usage and feasibility in relation to adolescent self-efficacy levels, and emotional and physical health.
 
  A single-center randomized controlled public school pits. Indications were toward beneficial effects on physical and mental health that warrant further research. Focus on time-specific attrition measures alongside daily times of usage and ways to increase participants' self-efficacy levels appear to be a promising avenue for research on mHealth interventions for adolescent populations with the aim to ultimately lower attrition rates.Tuberculosis is a chronic infectious disease endemic in Argentina most often localized in the lungs, caused by Mycobacterium tuberculosis. It usually afflicts poor population groups and has a significant impact on public health. COVID-19 is an acute viral disease caused by SARS-CoV-2 presenting with a typical respiratory localization, which eventually displays clinical and radiological similarities with pulmonary tuberculosis.  https://www.selleckchem.com/products/SP600125.html  Both entities can have a fatal outcome if they are not diagnosed and treated on time. We present a case series where pulmonary tuberculosis and COVID-19 were diagnosed simultaneously.Coronary involvement in COVID-19 infection usually presents as type 2 acute myocardial infarction (AMI), due to increased 02 consumption and reduction of oxygen supply, and less frequently as type 1 (STEMI). In that cases, thrombogenicity of the infection may contribute to acute coronary occlusion. We present 2 cases of middle-aged men, with few or none cardiovascular risk factors, who were in hospital during 10 days because pneumonia due to COVID-19 with good evolution. In the convalescent phase, one day after hospital discharge, and enoxaparin suspension, they went back to hospital because STEMI. Both were treated by direct angioplasty using pharmacologic stent. Discussion is related to treatment of AMI at discharge, if anticoagulation should be added to double antiplatelet therapy, and if any prophylactic antithrombotic treatment should be considered at discharge from COVID-19 pneumonia in some patients.Dengue is a mosquito-borne viral disease confined to the geographical areas where its vectors Aedes aegypti and Aedes albopictus are present. The transmission occurs mainly during the summer but it can extend to autumn months in warm climates. In our country, this year the seasonal transmission o f dengue overlapped with the COVID-19 pandemic, caused by SARS-CoV-2, a novel coronavirus responsible of serious respiratory conditions with eventual fatal outcomes. On the other hand, the HIV is a retrovirus that causes disease by weakening the immune system, favoring infections by numerous opportunistic pathogens. We present the case of an untreated HIV patient who developed simultaneous infection with dengue and SARS-CoV-2 with favorable evolution.The treatment of hypothyroidism is aimed at restoring the euthyroid state. In most cases, the signs and symptoms of thyroid deficiency generally resolve, which is particularly gratifying for the treating physician and mainly, for patients. However, there may be coexisting special situations that can potentially hinder or interfere with a successful treatment, as in the case of the elderly, patients suffering from heart disease, hematological diseases or dyslipidemia, hypothyroid patients who will undergo an emergency surgery, those with chronic kidney failure, or adrenal insufficiency, among others. Besides management of hypothyroidism in time of COVID-19 is also included. Some patients may experience intolerance to treatment and others persistent symptoms of hypothyroidism even under adequate replacement therapy, requiring a special approach. Being aware of these special situations will provide benefits to the patient and will also prevent treatment failure or complications.
