Aim: In this study we aimed to find the rate of human adenovirus (HAdV) infections and identify HAdVs molecular epidemiology in children younger than 5 years old with clinical diagnosis of severe acute respiratory infections in Iran. Patients & methods: A semi-nested PCR with in-house designed primers for HAdV was performed on 200 oropharyngeal swabs collected within 5 days from the onset of symptoms. The positive samples were subjected to sequencing and a phylogenetic tree was drawn. Results: Out of 200 specimens, 71 (35.5%) cases were positive for HAdVs. Detected strains matched with HAdV species B (80.3%), C (15.5%), D (2.8%) and E (1.8%). HAdV- B14/55 and HAdV-B3 were the most prevalent types, respectively. Conclusion: This study showed that infections with HAdV species B, were common in children, who were clinically diagnosed as severe acute respiratory infection cases in Iran. The results could be useful for future epidemiological researches.

BACKGROUND: Acute respiratory viral infections are ubiquitous. Part of the cases are severe and require hospital treatment. AIM: Studying the etiology of severe acute respiratory infections in patients of Ekaterinburg hospitals in different epidemic seasons (from 2017 to 2020). MATERIALS AND METHODS: 1,132 cases of severe acute respiratory infection were assessed. The structure of laboratory-confirmed cases was determined. RESULTS: In the assessed seasons, the proportion of respiratory viruses in the etiological structure of severe acute respiratory infections was 56.0% on average. B/Yamagata lineage of influenza viruses was predominant in the season of 2017/2018 (23.9% from the total number of respiratory viruses), influenza А (H1N1)pdm09 viruses were predominant in the season of 2018/2019 (27.7%), and influenza A and B viruses were identified in 2019/2020 (39.4% and 31.7%, respectively). СONCLUSIONS: The obtained results confirm a key role of influenza viruses in the etiology of severe acute respiratory infections among the hospital patients in different epidemic seasons.

Infeksi saluran pernafasan akut atau yang sering disebut ISPA merupakan infeksi pada saluran pernafasan baik saluran pernafasan atas atau bawah.ISPA juga kebanyakan terjadi pada anak balita karena daya tahan tubuh mereka tidak kuat dalam menghadapi penyakit ISPA. ISPA mengakibatkan kematiansekitar15%-20% per tahun pada usia balita di Negara berkembang. Tujuan penelitian ini adalah untuk mengetahui dan menganalisa peran ibu dalam meningkatkan sistem imun anak dengan ISPA.Metode penelitian yang digunakan dalam penelitian ini adalah kualitatif deskriptif dengan sampel purposive sampling.Populasi dan sampel penelitian ini adalah ibu yang mempunyai anak dengan riwayat dan saat ini menderita penyakit ISPA di Batu Gajah Kota Ambon.Partisipan dalam penelitian ini berjumlah 5 orang. Hasil dari penelitian mendapati 4 kategori yaitu pemberian nutrisi pada anak untuk memenuhi kebutuhan agar sistem imunnya terjaga, kebersihan lingkungan, peran ibu dalam melakukan pencegahan pada anaknya yang mengalami ISPA, dan  peran ibu dalam menjaga dan mempertahankan kesehatan anaknya.   Kata kunci: peran ibu, sistem imun, ispa THE ROLE OF MOTHERS IN INCREASING IMMUNE SYSTEM OF CHILDREN WITH ACUTE RESPIRATORY INFECTION    ABSTRACT Acute respiratory infections or often called ARI is an infection of the upper or lower respiratory tract. ARI occurs mostly in children under the age of five because their endurance is not strong in dealing with ARI. ARI results in deaths of around 15%-20% per year at the age of under-five in developing countries. The purpose of this study was to determine and analyze the role of mothers in improving the immune system of children against ARI. The research method used in this study was qualitative descriptive with a purposive sampling sample. Respondents and samples of this study were five mothers who had children with a history of ARI and currently suffering from the disease in Batu Gajah, Ambon City. The results of the study found 4 categories, namely providing nutrition to children to meet their needs so that their immune systems are maintained, clean environment, mother's role in preventing children with ARI, and mother's role to preserve and maintain the health of their children. The findings indicated that in terms of coping or improving the immune system of a child to avoid ARI, it is necessary to have role the of mothers in providing nutrition so that the immune system is boosted, besides that the mother can prevent and protect her child from various diseases, especially ARI. Keywords: role of mothers, immune system, acute respiratory infections

Due to the promising effects of mesenchymal stem cells (MSCs) in the treatment of various diseases, this commentary aimed to focus on the auxiliary role of MSCs to reduce inflammatory processes of acute respiratory infections caused by the 2019 novel coronavirus (COVID-19). Since early in 2020, COVID-19, a consequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly affected millions of people world-wide. The SARS-CoV-2 infection in children appears to be an unusual event. Despite the high number of affected adult and elderly, children and adolescents remained low in amounts, and marginally touched. Based on the promising role of cell therapy and regenerative medicine approaches in the treatment of several life-threatening diseases, it seems that applying MSCs cell-based approaches can also be a hopeful strategy for improving subjects with severe acute respiratory infections caused by COVID-19.

Background: Acute respiratory infections (ARI) and Malnutrition in children have tremendous burden on the health care sector of developing nations including India. The intensity with which these conditions are holding grip in the community is indeed a matter of concern and hence developing nations should develop an insight to assess the severity of it has become a necessity.Methods: A hospital based cross sectional study was carried out in children aged 0-14 years. Children were clinically assessed and diagnosis was made as URTI or LRTI Also anthropometry was performed and accordingly children were divided into categories of no malnutrition (NM), severe acute malnutrition (SAM) and moderate acute malnutrition (MAM) in ‘under 5’ years age children according to WHO guidelines, whereas children aged ‘above 5’ years were categorized as per the IAP guidelines.Results: It was observed that most of the mothers of children were illiterate with inadequate or absent ventilation and use of biomass fuels (chulha) for cooking purpose in households of rural children. The proportion of malnutrition was found to be equal in Under 5 children. In ‘above 5 years’ age study subjects, 52.4% of urban study subjects were normal as compared to 16.7% of rural study subjects.Conclusions: Our study implies that ARI and Malnutrition definitely is more prevalent in the pediatric population. Prevalence of URTI was found to be on a higher side in the rural population and LRTI prevalence was found to be higher in the urban population. Similarly, the prevalence of malnutrition was almost similar in ‘Under 5’ aged children, whereas the prevalence of malnutrition in ‘Above 5’ aged children was higher in the rural population than urban population.
