Abstract
OBJECTIVE This study examined the long-term effects of the COVID-19 pandemic on adolescents' substance use, digital media use, and symptoms of internet, gaming, and social media addiction. METHOD A nationally representative longitudinal cohort of 1665 Israeli teens and preteens, aged 9-16, completed questionnaires assessing substance use prevalence, daily screen time, symptoms of media addiction, and potential risk and protective factors. Data were collected before the pandemic (October 2019), after the second wave lockdown (November 2020), and after the fifth wave (April 2022) in Israel. RESULTS The analysis documented significant increases in substance use, daily screen time, and social media addiction indices over time. Gratitude, life satisfaction, positive emotions, future orientation, grit, and secure attachment emerged as significant protective factors. Sensation-seeking, negative emotions, and mental health symptoms were identified as risk factors. CONCLUSIONS These findings highlight the importance of educational and public mental health services in addressing the pandemic's long-term impact on the mental health and addictive behaviors of adolescents. They also emphasize the significance of enhancing protective factors and reducing risk factors to effectively mitigate substance and digital media abuse among adolescents.

Superior antibody and membrane protein-specific T-cell responses to CoronaVac by intradermal versus intramuscular routes in adolescents. World J Pediatr 2024; 20:353-370. [PMID: 38085470 PMCID: PMC11052846 DOI: 10.1007/s12519-023-00764-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 09/18/2023] [Indexed: 04/29/2024]
Abstract
BACKGROUND Optimising the immunogenicity of COVID-19 vaccines to improve their protection against disease is necessary. Fractional dosing by intradermal (ID) administration has been shown to be equally immunogenic as intramuscular (IM) administration for several vaccines, but the immunogenicity of ID inactivated whole severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the full dose is unknown. This study (NCT04800133) investigated the superiority of antibody and T-cell responses of full-dose CoronaVac by ID over IM administration in adolescents. METHODS Participants aged 11-17 years received two doses of IM or ID vaccine, followed by the 3rd dose 13-42 days later. Humoral and cellular immunogenicity outcomes were measured post-dose 2 (IM-CC versus ID-CC) and post-dose 3 (IM-CCC versus ID-CCC). Doses 2 and 3 were administered to 173 and 104 adolescents, respectively. RESULTS Spike protein (S) immunoglobulin G (IgG), S-receptor-binding domain (RBD) IgG, S IgG Fcγ receptor IIIa (FcγRIIIa)-binding, SNM [sum of individual (S), nucleocapsid protein (N), and membrane protein (M) peptide pool]-specific interleukin-2 (IL-2)+CD4+, SNM-specific IL-2+CD8+, S-specific IL-2+CD8+, N-specific IL-2+CD4+, N-specific IL-2+CD8+ and M-specific IL-2+CD4+ responses fulfilled the superior and non-inferior criteria for ID-CC compared to IM-CC, whereas IgG avidity was inferior. For ID-CCC, S-RBD IgG, surrogate virus neutralisation test, 90% plaque reduction neutralisation titre (PRNT90), PRNT50, S IgG avidity, S IgG FcγRIIIa-binding, M-specific IL-2+CD4+, interferon-γ+CD8+ and IL-2+CD8+ responses were superior and non-inferior to IM-CCC. The estimated vaccine efficacies were 49%, 52%, 66% and 79% for IM-CC, ID-CC, IM-CCC and ID-CCC, respectively. The ID groups reported more local, mild adverse reactions. CONCLUSION This is the first study to demonstrate superior antibody and M-specific T-cell responses by ID inactivated SARS-CoV-2 vaccination and serves as the basis for future research to improve the immunogenicity of inactivated vaccines.

INTERNATIONAL ORTHOPAEDICS 2024; 48:331-335. [PMID: 37668727 DOI: 10.1007/s00264-023-05966-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 08/30/2023] [Indexed: 09/06/2023]
Abstract
PURPOSE To evaluate the mortality rate, intensive care unit (ICU) referral, and Charlson comorbidity index (CCI) between different types of vaccinated and non-vaccinated patients operated on due to intertrochanteric femoral fracture (IFF) during the pandemic. METHODS Ninety-six patients (43 males, 53 females) who had proximal femur nails (PFN) for the IFF during the pandemic were included in the study. The patients were divided into four subgroups; non-vaccinated, and different types of vaccinated. Mortality rates, ICU referrals, and CCI relations were evaluated. RESULTS No significant difference was observed in terms of demographic data such as age, gender, side, CCI, and ICU referrals between the subgroups (p = 0.164, p = 0.546, p = 0.703, p = 0.771, p = 0.627 respectively). The mortality rate was significantly lower in the Sinovac + BioNTech subgroup (p = 0.044). CONCLUSION No relationship was found between mortality rate, ICU referral, and CCI in different types of vaccinated and non-vaccinated patient subgroups.
