Physical activity counselling can target cognitive-affective participation barriers, but counselling benefits for children with medical conditions/disabilities were unknown. This study investigated successes, challenges, and the impact of physical activity counselling on children and their families. One-on-one semi-structured interviews were completed with 7 patients (2 male/5 female, aged 13–17) and 4 parents who participated in 2–8 weekly counselling sessions (2015–2020). Interviews were recorded and transcribed verbatim for inductive thematic analyses. Counselling encouraged positive mindset changes (viewing physical activity more holistically, making it "more fun and manageable", helping them to "learn how to love moving and doing sports"). Participants felt strong support (feeling heard, validated, and provided with "hope... that we can still achieve things... even though it may seem like there's limitations"). Counselling was viewed positively. The intent to improve active lifestyle attitudes and confidence was reflected in positive, primarily cognitive-affective (motivation for activity, "more general skills of having a positive attitude towards physical activity and the willingness to try new things") outcomes. More sessions, additional resources to keep, and follow-up after counselling completion were recommended to support behaviour change. Future research should evaluate enhanced counselling services and comparing children who have and have not received such counselling. [ABSTRACT FROM AUTHOR]

Background: Adenovirus affects mainly the respiratory system, leading to life-threatening pneumonia. This study was aimed to describe the epidemiological, clinical, biochemical, and radiological profile and respiratory sequelae during follow-up among children with severe adenoviral pneumonia (ADVP) admitted in a tertiary care pediatric intensive care unit (PICU). Subjects and Methods: This is a single-center, prospective study conducted in PICU from eastern India from December 2018 to August 2021. Children less than 10 years of age, admitted with features suggestive of lower respiratory tract infection (LRTI)/pneumonia and positive for adenovirus by respiratory polymerase chain reaction during the study period were included. All children were managed symptomatically. Antibiotics were used in all children and respiratory support was given according to the severity as per standard management protocol. Results: Among 96 children with adenoviral pneumonia, 33 (34.4%) had severe ADVP and required PICU care. Among them, 28 (84.8%) were males and 24 (72.7%) had SPO2 <90% at the time of admission. Twenty (60%) children needed some respiratory support beyond simple oxygen therapy. Among 33 children, 9 (27.3%) died, 2 left against medical advice, and 22 (66.7%) survived and were discharged. Among discharged, 2 (9%) were lost in follow-up and 20 (91%) children were followed up for the next 2.5 years. During the follow-up, 18 (90%) had recurrent symptoms, and high-resolution computed tomography showed features suggestive of postinfective bronchiolitis obliterans in most of them. Conclusions: Unlike other respiratory viruses, ADVP had a longer course of illness, seemed to be more severe, and had more long-term sequelae. [ABSTRACT FROM AUTHOR]

Purpose: Sleep disturbances and poor sleep quality are known to be present in patients with CF. Regular physical activity plays an important role in the treatment of CF patients due to its positive influence on progression of disease and quality of life. The aim of this work is to create a home-based sleep and activity profile and to investigate the influence of habitual physical activity (HPA) on sleep quality in children, adolescents, and adults with CF. Methods: A total of 109 CF patients (64 male, mean age 22.7 ± 12.0 years; mean ppFEV1 63.0 ± 26.7) were equipped with an actigraph for a home-based collection of data on sleep and activity over 4 weeks. Results: Age, FEV1, and BMI affect sleep and activity in CF patients. Especially younger age and higher FEV1 show a great influence on certain aspects of sleep (SE, TST, TIB, WASO, # of awakenings) and activity and its different intensities. General HPA does not affect sleep, but there is a strong correlation between times spent in vigorous to very vigorous intensities and better sleep quality. Conclusion: Besides younger age and higher FEV1, daily activity in higher intensities influences sleeping behavior of CF patients in a positive way. Patients with poor sleep quality and sleep disturbances possibly benefit from an intensification of physical activity in the home environment.

Background: Human adenoviruses (HAdV) play a significant role in pediatric respiratory tract infections. To date, over 60 types of HAdV have been identified. Here, HAdV types are characterized in children in the Beijing area with acute lower respiratory tract infections (ALRTIs) and the clinical features and laboratory findings of hospitalized HAdV-infected cases are described.Methods: Respiratory specimens were collected from pediatric patients with ALRTIs in the emergency department or from those admitted to Beijing Children's Hospital between March 2007 and December 2012. Infections with common respiratory viruses were determined by PCR or RT-PCR. HAdV positive samples were further typed by PCR and sequencing.Results: Among 3356 patients with ALRTIs, 194 (5.8 %) were found to have HAdV infection. HAdV infection was primarily confined to children (88.35 %) less than 5 years of age. A total of 11 different types of HAdV were detected throughout the study period, with HAdV-B7 (49.0 %) and HAdV-B3 (26.3 %) as the most prevalent types, followed by HAdV-C2 (7.7 %) and HAdVC1 (4.6 %). Newly emerging and re-emergent types or variants, HAdV-B55 (n = 5), HAdV-C57 (n = 3), and HAdV-B14p1 (n = 1), were identified. Results also included the reported first case of co-infection with HAdV-C2 and HAdV-C57. Clinical entities of patients with single HAdV infection (n = 49) were similar to those with mixed HAdV/respiratory syncytial virus (RSV) infections (n = 41). Patients with HAdV-B7 infection had longer duration of fever and higher serum levels of muscle enzymes than HAdV-B3-infected patients.Conclusions: During the study period, HAdV-B7 and HAdV-B3 were the predominant types identified in pediatric ALRTIs. HAdV-B7 infection tends to have more severe clinical consequences. The presence of newly emerging types or variants and co-infection with different types of HAdV highlights the need for constant and close surveillance of HAdV infection. [ABSTRACT FROM AUTHOR]

Background: There is scarcity of data regarding epidemiology and clinical aspects of human adenovirus acute respiratory infection (ARI) among children in developing countries. Methods: Retrospective data on demographics, clinical presentation, outcomes and laboratory findings of 116 children admitted into Tuanku Jaafar Hospital in Seremban, Malaysia from 2012 to 2013 with documented diagnosis of community-acquired adenovirus ARI were collected and analyzed. Results: Male to female ratio was 1.70. Median age was 14 (1-107) months. The commonest symptoms were fever (94.8%; 110/116), cough (82.8%, 96), rhinorrhea (63.8%; 74), interrupted feeding (66.4%; 77), diarrhea (33.6%; 39) and conjunctivitis (21.6%; 25). Mean temperature on admission was 38.48°C±0.98°C. Among all 116 subjects, 20.7% (24) needed oxygen supplementation, 57.8% (67) required intravenous hydration, 11.2% (13) were admitted into the pediatric intensive care unit and 6.9% (8) required mechanical ventilation. Only 1% (1/87) had positive blood culture (Streptococcus pneumoniae) among 87 who received antibiotic treatment. Case fatality rate was 2.6% (3/116) and 1.7% (2/116) developed bronchiolitis obliterans. Median length of hospital stay was 4 (1-50) days. Conclusion: Adenovirus ARI caused significant morbidity and substantial resource utilization among hospitalized Malaysian children. It should be considered in the differential diagnosis of infants below two years presenting with ARI associated with high fever. Antibiotics should not be prescribed as secondary bacterial infections are uncommon. [ABSTRACT FROM AUTHOR]

Human adenoviruses (HADVs) comprise at least 54 types and cause a wide spectrum of respiratory tract infections; early diagnosis and epidemiological monitoring of HADV infections requires a rapid and sensitive assay. The use of a real-time polymerase chain reaction (PCR) assay was evaluated with one set of in-house designed primers for respiratory adenoviral infections. The assay was first validated by detecting successfully 6 representative types and 100 clinical isolates. A concomitant prospective surveillance of viral aetiology using conventional cultures and PCR assays in 160 febrile children with acute respiratory tract symptoms was conducted between May 2010 and July 2011. Viral aetiologies were confirmed in 72 (45%) cases using conventional cultures, including 51 adenoviral infections. The concordance between the real-time PCR and culture was good (Kappa = 0.94), and two additional culture-negative adenovirus infections were identified. During the study period (January 2011), an adenoviral community epidemic occurred. Adenovirus B3 was the predominant type in this epidemic (69.8%), followed by C2 (5.7%), C1 (5.7%), C5 (1.9%), E4 (1.9%), C6 (1.9%), F41 (1.9%), and 4 unclassified species C (7.5%). Significantly prolonged duration of fever (>5 days), higher leukocyte counts, higher neutrophil counts, and higher C-reactive protein levels were in the adenoviral infected group (n = 53, P < 0.001), compared with the non-adenoviral infected group (n = 107). In conclusion, this in-house real-time PCR is capable of detecting adenoviral respiratory infections of various types in children; and patients with adenoviral aetiology suffered from more severe clinical manifestations.

Acute respiratory tract infection is an important cause of morbidity and mortality with a worldwide disease burden. This study aimed to determine the prevalence and clinical characteristics of children with viral-induced acute respiratory tract infection, in Southern China. Nasopharyngeal aspirate samples from 1,980 pediatric patients with suspected acute respiratory tract infection, and 82 samples from healthy subject controls were collected for routine examination at the Second Affiliated Hospital of Shantou University Medical College, from October 2007 to August 2011. Specimens were tested by multiplex polymerase chain reaction (mPCR). At least one or more viruses were detected from 1,087 samples (54.9%). These included laboratory confirmations for 446 respiratory syncytial virus (RSV), 386 influenza virus A (FluA), 315 human rhinovirus (HRV), 135 human bocavirus (HBoV), 119 Parainfluenza virus 3 (PIV3), 82 Parainfluenza virus 1 (PIV1), 66 adenovirus (ADV), 53 WU polyomavirus (WUPyV), 52 human metapneumovirus (hMPV), and 29 influenza virus B (FluB) samples. Samples from healthy subjects were negative for any virus. Of the patients with positive specimens, 107 (9.8%) were admitted to pediatric intensive care unit (PICU). Co-infection with at least two of the viral pathogens under study was observed in 325 of the 1,980 patients (16.4% of the total number of cases). These findings may help in the diagnosis of viral infections of the respiratory tract in children, and help to consider current and potential therapeutic approaches for the treatment of acute respiratory tract infection, and further respiratory complications.

Human Adenoviruses (HAdV) are known to be potentially associated with strong inflammatory responses and morbidity in pediatric patients. Although most of the primary infections are self-limiting, the severity of clinical presentation, the elevation of the white blood cell count and inflammatory markers often mimic a bacterial infection and lead to an inappropriate use of antibiotics. In infections caused by HAdV, rapid antigen detection kits are advisable but not employed routinely; costs and feasibility of rapid syndromic molecular diagnosis may limit its use in the in-hospital setting; lymphocyte cultures and two-sampled serology are time consuming and impractical when considering the use of antibiotics. In this review, we aim to describe the principal diagnostic tools and the immune response in HAdV infections and evaluate whether markers based on the response of the host may help early recognition of HAdV and avoid inappropriate antimicrobial prescriptions in acute airway infections.
