RESUMEN
The unmet need for mental health care is a global concern. There is a lack of cross-cultural studies examining adolescent help-seeking behavior from both formal and informal sources, including both high-and lower-income countries. This study investigates mental health help-seeking behavior in eight Asian and European countries. Data from 13,184 adolescents aged 13-15 (51% girls) was analysed using mixed-effects logistic regression with school-wise random intercepts to compare countries and genders. Although a significant proportion of adolescents considered getting or sought informal help, formal help-seeking remained exceptionally low, especially in middle-income countries (< 1%), while it ranged from 2 to 7% in high-income countries. Among adolescents with high emotional and behavioral problems (scoring above the 90th percentile on the Strengths and Difficulties Questionnaire), 1-2% of those in middle-income countries and 6-25% of those in high-income countries sought formal help. Girls generally seek more help than boys. The study shows the most adolescents do not receive formal help for mental health problems. The unmet need gap is enormous, especially in lower-income countries. Informal sources of support, including relatives, peers, and teachers, play a crucial role, especially in lower-income countries.
RESUMEN
A descriptive cross sectional study was implemented in 34 patients with the spinal lumbar disc hernia in the neurological department of Bach Mai Hospital during 1/1999-12/2000. The rate of male/female was 1.83/1, the youngest patients was 29 and oldest patients was 73. The results have shown that syndrome of spinal lumbar pain occurred in 79.41% of patients, the radiculoneurogical syndrome accompanying the kinetic disorder found in 97.16% of patients, sensation disorders was in 91.18%, reflex disorder was in 88.25%, nutrition disorder was in 58.82% of patients. There was correspondence between clinical feature and images of magnetic resonance in disc hernia with lesions of 1 or 2 of neurological radixes in the same disc layer and between the level of spinal canal stenosid and grade of disc hernia. There was no correspondence between the clinical features and images of magnetic resonance in the lesion of 2 neurological radixes in the same side or more than neurological radixes

Background: WHO recommends that malaria drug should be used with essential elements which are derivatives of artemisinin (ART) for treatment phase and limit the development of parasite (MIC). Objective: To assess in vitro effect of artemisinin powder and 10 alpha- trifluoro methyl hydroartemisinin (TEMHA) in powder and tablet form to P.falciparum. Subject and Method: 48h in vitro test of Phuc Nguyen Dinh was applied to this study. Results and Conclusions: The results showed that: for T996, IC50 values of ART, 10 alpha- TEMHA powder and 10 alpha- TEMHA pill were as follows: 37.8; 16.4 and 17.6 nM/L, respectively. For K1, IC50 values of ART, 10 alpha- TEMHA powder and 10 alpha- TEMHA pill were: 22.8; 11.4 and 12.2 nM/L, respectively. MIC values of artemisinin powder, 10 alpha- TEMHA powder and pill for T996 were as follows: 100; 40 and 40nM/L, respectively. For K1, MIC values of ART, 10 alpha- TEMHA powder and pill are: 76; 24; 32 nM/L, respectively.
RESUMEN
Vaccines against SARS-CoV-2 have shown high efficacy in clinical trials, yet a full immunologic characterization of these vaccines, particularly within the upper respiratory tract, remains lacking. We enumerated and phenotyped T cells in nasal mucosa and blood before and after vaccination with the Pfizer-BioNTech COVID-19 vaccine (n =21). Tissue-resident memory (Trm) CD8+ T cells expressing CD69+CD103+ expanded [~]12 days following the first and second doses, by 0.31 and 0.43 log10 cells per swab respectively (p=0.058 and p=0.009 in adjusted linear mixed models). CD69+CD103+CD8+ T cells in the blood decreased post-vaccination. Similar increases in nasal CD8+CD69+CD103-T cells were observed, particularly following the second dose. CD4+ Th17 cells were also increased in abundance following both doses. Following stimulation with SARS-CoV-2 spike peptides, CD8+ T cells increased expression of CD107a and CD154. These data suggest that nasal T cells may be induced and contribute to the protective immunity afforded by this vaccine.
RESUMEN
Production of affordable coronavirus disease 2019 (COVID-19) vaccines in low- and middle-income countries is needed. NDV-HXP-S is an inactivated egg-based Newcastle disease virus (NDV) vaccine expressing the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Wuhan-Hu-1. The spike protein was stabilized and incorporated into NDV virions by removing the polybasic furin cleavage site, introducing the transmembrane domain and cytoplasmic tail of the fusion protein of NDV, and introducing six prolines for stabilization in the prefusion state. Vaccine production and clinical development was initiated in Vietnam, Thailand, and Brazil. Here the interim results from the first stage of the randomized, dose-escalation, observer-blind, placebo-controlled, phase 1/2 trial conducted at the Hanoi Medical University (Vietnam) are presented. Healthy adults aged 18-59 years, non-pregnant, and with self-reported negative history for SARS-CoV-2 infection were eligible. Participants were randomized to receive one of five treatments by intramuscular injection twice, 28 days apart: 1 g +/-CpG1018 (a toll-like receptor 9 agonist), 3 g alone, 10 g alone, or placebo. Participants and personnel assessing outcomes were masked to treatment. The primary outcomes were solicited adverse events (AEs) during 7 days and subject-reported AEs during 28 days after each vaccination. Investigators further reviewed subject-reported AEs. Secondary outcomes were immunogenicity measures (anti-spike immunoglobulin G [IgG] and pseudotyped virus neutralization). This interim analysis assessed safety 56 days after first vaccination (day 57) in treatment-exposed individuals and immunogenicity through 14 days after second vaccination (day 43) per protocol. Between March 15 and April 23, 2021, 224 individuals were screened and 120 were enrolled (25 per group for active vaccination and 20 for placebo). All subjects received two doses. The most common solicited AEs among those receiving active vaccine or placebo were all predominantly mild and included injection site pain or tenderness (<58%), fatigue or malaise (<22%), headache (<21%), and myalgia (<14%). No higher proportion of the solicited AEs were observed for any group of active vaccine. The proportion reporting vaccine-related AEs during the 28 days after either vaccination ranged from 4% to 8% among vaccine groups and was 5% in controls. No vaccine-related serious adverse event occurred. The immune response in the 10 g formulation group was highest, followed by 1 g +CpG1018, 3 g, and 1 g formulations. Fourteen days after the second vaccination, the geometric mean concentrations (GMC) of 50% neutralizing antibody against the homologous Wuhan-Hu-1 pseudovirus ranged from 56.07 IU/mL (1 g, 95% CI 37.01, 84.94) to 246.19 IU/mL (10 g, 95% CI 151.97, 398.82), with 84% to 96% of vaccine groups attaining a [≥] 4-fold increase over baseline. This was compared to a panel of human convalescent sera (N=29, 72.93 95% CI 33.00-161.14). Live virus neutralization to the B.1.617.2 (Delta) variant of concern was reduced but in line with observations for vaccines currently in use. Since the adjuvant has shown modest benefit, GMC ratio of 2.56 (95% CI, 1.4 - 4.6) for 1 g +/-CpG1018, a decision was made not to continue studying it with this vaccine. NDV-HXP-S had an acceptable safety profile and potent immunogenicity. The 3 g dose was advanced to phase 2 along with a 6 g dose. The 10 g dose was not selected for evaluation in phase 2 due to potential impact on manufacturing capacity. ClinicalTrials.gov NCT04830800.
