Exploring knowledge of parents and caregivers on cancer symptoms in children: an observational study regarding the need for educational tools and health promotion in low- and middle-income countries.

BACKGROUND: Although most cases of childhood cancer are unlikely to be prevented, by today's standards, most children with cancer can now be cured. However, disparities about survival exist among countries; in Mexico, the overall survival is 49.6%, with 70% of childhood cancers diagnosed at advanced stages. Therefore, parents and caregivers must have optimal knowledge of the early signs and symptoms of childhood malignancies as they are largely non-specific. This study was designed to explore the current knowledge of childhood cancer among parents and caregivers in Mexico and identify the need for education and health promotion in low- and middle-income countries. METHODS: An online survey of 112 parents and caregivers was performed to assess their knowledge of childhood cancer, focusing on the signs and symptoms and early diagnostic strategies. RESULTS: Sixty-nine (61.6%) mothers, 23 (20.5%) fathers, 17 (15.2%) familiar caregivers, and 3 (2.7%) non-familiar caregivers responded. Forty-six (41.1%) respondents said that they knew a child diagnosed with cancer, 92.9% mentioned leukemia as the most common type of cancer among children, the most highly ranked option when asked which sign/symptom they considered as a warning for suspicion was growth/lump in any part of the body, 97.3% considered that an early diagnosis is related to a higher cure rate, and 92.9% expressed the desire to receive reliable information about childhood cancer. CONCLUSIONS: Although parents and caregivers have some knowledge of childhood cancer, there are concepts that should be reinforced to improve their understanding of this group of diseases, as they are the frontline for children to seek medical attention. In the future, the use of tools that help educate more caregivers will strengthen knowledge and contribution regarding this issue and promote the generation of public policies that support the early diagnosis of childhood cancer.

Parents and school-aged children's mental well-being after prolonged school closures and confinement during the COVID-19 pandemic in Mexico: a cross-sectional online survey study.

OBJECTIVE: This study aimed to determine parents' and school-aged children's mental well-being after experiencing confinement and prolonged school closures during the COVID-19 pandemic. DESIGN: Using a cross-sectional design, an online survey was applied to parents of school-aged children inquiring about their mental well-being and COVID-19 pandemic changes in their home and working lives. To assess the presence of depression, anxiety and stress in parents, the participants responded to the Depression, Anxiety and Stress Scale - 21 scale. To assess psychosocial dysfunction and sleep disturbances in children, participants responded to the Pediatric Symptom Checklist and the Children Sleep Habits Questionnaire. RESULTS: A total of 209 parents answered the questionnaire, most of them were female (87.1%) with a mean age of 40 years. The prevalence of anxiety, stress and parental depression symptoms were 35.9%, 28.2% and 25.4%, respectively. Children's mean age was 8.9 years, the prevalence of children's psychosocial dysfunction was 12%, while their sleep disturbance symptoms were 59.8%. 10.5% of children were suffering both outcomes. We found a bidirectional relationship between parents' and children's mental health outcomes. Parental depression symptoms were associated with experiencing COVID-19 infection within the household, having children with pre-existing medical diagnoses, children's psychosocial dysfunction and sleep disturbances. Children's psychosocial dysfunction was associated with parental depression and changes in their school routine. Children's sleep disturbances were associated with parental anxiety, younger age, increased use of electronic devices, night-time awakenings and shorter sleep time. CONCLUSION: Our results support the impact of long confinement and school closure due to the COVID-19 pandemic in Mexican children and parents' mental well-being. We advocate for specific mental health interventions tailored to respond to parents and children at risk of mental well-being distress.

Description of the 'pronation manoeuvre' for the diagnosis of developmental hip dysplasia.

Introduction: Without a prompt diagnosis, developmental dysplasia of the hip (DDH) in infants can lead to severe sequelae. Current screening strategies emphasize the use of Ortolani and Barlow physical examination manoeuvres, yet they exhibit low sensitivity. The purpose of this study is to evaluate the performance of a new physical examination tool (the pronation manoeuvre) as a screening tool for DDH. Methods: To evaluate the new manoeuvre, a cross-sectional and analytic study was performed with a nonprobabilistic sampling method. Patients with either a positive Ortolani or Barlow manoeuver were evaluated with the new manoeuvre and hip ultrasound. Controls were infants with negative Ortolani, Barlow and pronation manoeuvres and also had ultrasound performed. Results: DDH was confirmed in 83 of 130 cases (64%) and 2 of 130 controls (2%). The new pronation manoeuvre had a sensitivity of 76% and a specificity of 94% as compared to the Ortolani and Barlow manoeuvres (sensitivity 31 to 32%, specificity 93 to 100%) (P<0.05). Conclusion: This new physical examination manoeuvre could serve as another clinical tool for the initial screening of DDH in newborns. Its promising results against traditional screening procedures might potentially impact diagnosis and prognosis for patients with DDH.
