Children patients with COVID-19: How can parental and peer support lessen the psychological burden of isolation.

AIM: To assess the effect of parental and peer support on children's self-esteem during the isolation period in COVID-19-infected children is the main objective of this study. DESIGN: This is a descriptive cross-sectional study. One hundred ninety children with a confirmed diagnosis of COVID-19 were included. METHODS: A survey questionnaire to assess family and children's demographic characteristics was used for this study. A 13-item scale to assess parental support during the isolation period and a 10-item scale to assess peers' support during the isolation period were evaluated. Along with it, a 10-item scale to assess self-esteem during the isolation period was also measured. RESULTS: Home isolation was associated with higher parental and peer support scores than hospital isolation. The mean age of study participants was 13.23 ± 4.05 years; 52.6% were isolated at home versus 47.4% in hospital isolation. Phone calling and WhatsApp/messenger chat were methods of communication for 44.2% and 33.2% of patients, respectively. 6.3% of them had no method of communication. Child self-esteem was significantly affected by both parental and peer support during isolation. The increase in pronounced negative psychological effects such as disorientation, anger, low self-esteem and post-traumatic distress may be caused by a lack of parental care. NO PATIENT OR PUBLIC CONTRIBUTION TO THIS STUDY: Patients or the general public were not involved in the design, analysis or interpretation of the data in this study. The study's aim and objectives were developed based on children's self-esteem, which was limited by questionnaire data information, so the researchers completed demographic and disease-related questionnaires by interviewing them.

Endothelial Insulin Resistance Exacerbates Experimental Periodontitis.

Epidemiological studies suggest that the severity of periodontitis is higher in people with diabetes than in healthy individuals. Insulin resistance might play a crucial role in the pathogenesis of multiple diabetic complications and is reportedly induced in the gingiva of rodents with type 2 diabetes; however, the molecular mechanisms underlying the pathogenesis of diabetes-related periodontitis remain unclear. Therefore, we aimed to investigate whether endothelial insulin resistance in the gingiva may contribute to the pathogenesis of periodontitis as well as elucidate its underlying molecular mechanisms. We demonstrated that insulin treatment downregulated lipopolysaccharide (LPS)-induced or tumor necrosis factor α (TNFα)-induced VCAM1 expression in endothelial cells (ECs) via the PI3K/Akt activating pathway, resulting in reduced cellular adhesion between ECs and leukocytes. Hyperglycemia-induced selective insulin resistance in ECs diminished the effect of insulin on LPS- or TNFα-stimulated VCAM1 expression. Vascular endothelial cell-specific insulin receptor knockout (VEIRKO) mice exhibited selective inhibition of the PI3K/Akt pathway in the gingiva and advanced experimental periodontitis-induced alveolar bone loss via upregulation of Vcam1, Tnfα, Mcp-1, Rankl, and neutrophil migration into the gingiva compared with that in the wild-type (WT) mice despite being free from diabetes. We also observed that insulin-mediated activation of FoxO1, a downstream target of Akt, was suppressed in the gingiva of VEIRKO and high-fat diet (HFD)-fed mice, hyperglycemia-treated ECs, and primary ECs from VEIRKO. Further analysis using ECs transfected with intact and mutated FoxO1, with mutations at 3 insulin-mediated phosphorylation sites (T24A, S256D, S316A), suggested that insulin-mediated regulation of VCAM1 expression and cellular adhesion of ECs with leukocytes was attenuated by mutated FoxO1 overexpression. These results suggest that insulin resistance in ECs may contribute to the progression of periodontitis via dysregulated VCAM1 expression and cellular adhesion with leukocytes, resulting from reduced activation of the PI3K/Akt/FoxO1 axis.

INTESTINAL PARASITIC INFECTION IN EGYPTIAN CHILDREN: COULD IT BE A RISK FACTOR FOR IRON DEFICIENCY ANEMIA?.

A case control study that associates IDA with different parasitic infections and socioeconomic factors. The study enrolled 194 children with IDA and 180 age matched control. Patients diagnosed as IDA by complete blood count (CBC), and iron indices. All cases were subjected to complete history, anthropometric measures, and CBC and stool analysis. Ancylostoma duodenal, Ascaris lumbercoides and Giardia lamblia infections, lower family income, increased number of family members and eating meat in low frequency could be independent risk factors for IDA as detected by multivariate regression analysis. A. duodenale and G. lamblia were associated with lower ferritin levels in anemic patients. No significant associations as regards residence, body mass index, mother employment or education levels (p>0.05).
