    © 2016 by the authors; licensee MDPI, Basel, Switzerland. The Human Papillomavirus (HPV) vaccine has the great potential to prevent HPV-related infections for millions of women and men worldwide. However, the success of the vaccine is highly dependent on the vaccination rate. Factors influencing the attitudes of undergraduate students towards HPV vaccination should be studied. This is a cross-sectional survey that was conducted to estimate the HPV vaccination rate among undergraduate students in Hong Kong, and to identify the predictors of their attitude towards HPV vaccination. The results showed that the HPV vaccination rate was 13.3%. Factors related to knowledge of vaccination were the main predictors of the studentsâ attitude towards vaccination (there were seven predictors, with B = 1.36 to 2.30; p < 0.05), followed by gender (B =-1.40; p < 0.05), acceptable maximum price (B = 0.35; p < 0.05), and willingness to receive the HPV vaccine if it can protect against cervical/anal cancer and genital warts (B =-1.90; p < 0.001).Theregressionmodelthatwasdevelopedbasedonthepredictorshadamoderateeffect size (adj-R 2 = 0.33). To conclude, the HPV vaccination rate among undergraduate students in Hong Kong was low. They should be provided with more active education and activities to promote HPV vaccination to improve their knowledge on the subject.Link_to_subscribed_fulltex

    Efficacy and effectiveness of inactivated vaccines against symptomatic COVID-19, severe COVID-19, and COVID-19 clinical outcomes in the general population: a systematic review and meta-analysis

    BACKGROUND: Inactivated, whole-virion vaccines have been used extensively in the SARS-CoV-2 pandemic. Its efficacy and effectiveness across regions have not been systematically evaluated. Efficacy refers to how well a vaccine performs in a controlled environment. Effectiveness refers to how well it performs in real world settings. METHODS: This systematic review and meta-analysis reviewed published, peer-reviewed evidence on all WHO-approved inactivated vaccines and evaluated their efficacy and effectiveness against SARS-CoV-2 infection, symptomatic infection, severe clinical outcomes, and severe COVID-19. We searched Pubmed (including MEDLINE), EMBASE (via OVID), Web of Science Core Collection, Web of Science Chinese Science Citation Database, and Clinicaltrials.gov. FINDINGS: The final pool included 28 studies representing over 32 million individuals reporting efficacy or effectiveness estimates of complete vaccination using any approved inactivated vaccine between January 1, 2019 and June 27, 2022. Evidence was found for efficacy and effectiveness against symptomatic infection (OR 0.21, 95% CI 0.16–0.27, I2 = 28% and OR 0.32, 95% CI 0.16–0.64, I2 = 98%, respectively) and infection (OR 0.53, 95% CI 0.49–0.57, I2 = 90% and OR 0.31, 95% CI 0.24–0.41, I2 = 0%, respectively) for early SARS-CoV-2 variants of concern (VoCs) (Alpha, Delta), and for waning of vaccine effectiveness with more recent VoCs (Gamma, Omicron). Effectiveness remained robust against COVID-related ICU admission (OR 0.21, 95% CI 0.04–1.08, I2 = 99%) and death (OR 0.08, 95% CI 0.00–2.02, I2 = 96%), although effectiveness estimates against hospitalization (OR 0.44, 95% CI 0.37–0.53, I2 = 0%) were inconsistent. INTERPRETATION: This study showed evidence of efficacy and effectiveness of inactivated vaccines for all outcomes, although inconsistent reporting of key study parameters, high heterogeneity of observational studies, and the small number of studies of particular designs for most outcomes undermined the reliability of the findings. Findings highlight the need for additional research to address these limitations so that more definitive conclusions can be drawn to inform SARS-CoV-2 vaccine development and vaccination policies.

    Validating the Efficacy of an Established Micropropagation Protocol for Commercial Propagation of Neolamarckia cadamba

    Background and Objective: Micropropagation is an efficient technique for mass-producing superior clones used in establishing planted forests. However, there is a lack of comprehensive reports on the effectiveness and reliability of the established micropropagation protocol for Neolamarckia cadamba. The aim of this study was to demonstrate the effectiveness and reliability of the established micropropagation protocol for mass propagating true-to-type N. cadamba clones. Materials and Methods: Two selected candidates plus trees of N. cadamba were cultured in B5 media supplemented with 0.8 mg L–1 BAP for shoot multiplication and in ½ B5 media supplemented with 0.1 mg L–1 PBZ for root regeneration. The growth performance, the presence of phytopathogens and morphological differences were investigated. The collected data were subjected to a two-tailed t-test (p<0.05). Results: The results showed no significant variation (p<0.05) in the number of shoots regenerated from each explant compared to the reference clone N5 (B39 = 4.6, B42 = 4.3 and N5 = 4.8). Moreover, the rooting patterns of the investigated clones (B39 = 14.5 and B42 = 9.4) significantly outperformed clone N5 (6.9), with over 90% successful root regeneration. Phytopathogen analysis using ERIC-PCR assay confirmed that the in vitro regenerants were free of any phytopathogens. Additionally, histological examination revealed no significant differences between the stock plants and in vitro regenerants. Conclusion: This study successfully ascertained the effectiveness and reliability of the established micropropagation protocol for mass propagating true-to-type N. cadamba clones

    Exogenous lipoid pneumonia associated with oil pulling: Report of two cases

    Two ladies with history of carcinoma of tongue presenting with un-resolving pneumonia were ultimately diagnosed to have lipoid pneumonia, and both were subsequently found to be associated with the practice of oil pulling which is a popular complementary therapy. Apart from cessation of oil pulling, they were treated with repeated therapeutic lobar broncho-alveolar lavage. despite the potential benefits of oil pulling on oral health, people especially those at risk of aspiration, should be properly informed of this potential risk when considering this form of complementary therapy
