    Objective: To associate the OHRQoL and HRQoL in mixed dentition children with the influence on age range, socioeconomic and clinical variables. Material and Methods: A cross-sectional study was carried out with 1,240 children between 6 and 12 years of age. HRQoL was assessed by the Quality of Life Assessment Scale, considered an outcome variable. OHRQoL was determined using specific questionnaires related to the age group: Oral Health Impact Scale in Early Childhood, Child Perceptions Questionnaire for 8 to 10 years, and 11 to 12 years. Dental caries and malocclusion were diagnosed. The socioeconomic class was evaluated. A multiple negative binomial regression analysis was used to test the relationship between HRQoL, OHRQoL scores and socioeconomic and clinical variables. Correlation analyses were performed between the total HRQoL and OHRQoL, with a significance level of 5%. Results: The HRQoL is inversely related to the impact of OHRQoL (p<0.05), modulated by the age group. There was a significant weak negative correlation between the HRQoL scores and the impact of OHRQoL (p<0.05). Conclusion:The OHRQoL impacts the HRQoL, modulated by the age group and with minor influence from socioeconomic and clinical variables

    In January 2020, Chinese health authorities identified a novel coronavirus strain never before isolated in humans. It quickly spread across the world, and was eventually declared a pandemic, leading to about 310 million confirmed cases and to 5,497,113 deaths (data as of 11 January 2022). Influenza viruses affect millions of people during cold seasons, with high impacts, in terms of mortality and morbidity. Patients with comorbidities are at a higher risk of acquiring severe problems due to COVID-19 and the flu-infections that could impact their underlying clinical conditions. In the present study, knowledge, attitudes, and opinions of the general population regarding COVID-19 and influenza immunization were evaluated. A multicenter, web-based, cross-sectional study was conducted between 10 February and 12 July 2020, during the first wave of SARS-CoV-2 infections among the general population in Italy. A sample of 4116 questionnaires was collected at the end of the study period. Overall, 17.5% of respondents stated that it was unlikely that they would accept a future COVID-19 vaccine (n = 720). Reasons behind vaccine refusal/indecision were mainly a lack of trust in the vaccine (41.1%), the fear of side effects (23.4%), or a lack of perception of susceptibility to the disease (17.1%). More than 50% (53.8%; n = 2214) of the sample participants were willing to receive flu vaccinations in the forthcoming vaccination campaign, but only 28.2% of cases had received it at least once in the previous five seasons. A higher knowledge score about SARS-CoV-2/COVID-19 and at least one flu vaccination during previous influenza seasons were significantly associated with the intention to be vaccinated against COVID-19 and influenza. The continuous study of factors, determining vaccination acceptance and hesitancy, is fundamental in the current context, in regard to improve vaccination confidence and adherence rates against vaccine preventable diseases

    The decay BΛc+ΛˉcKB^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} is studied in proton-proton collisions at a center-of-mass energy of s=13\sqrt{s}=13 TeV using data corresponding to an integrated luminosity of 5 fb1\mathrm{fb}^{-1} collected by the LHCb experiment. In the Λc+K\Lambda_{c}^+ K^{-} system, the Ξc(2930)0\Xi_{c}(2930)^{0} state observed at the BaBar and Belle experiments is resolved into two narrower states, Ξc(2923)0\Xi_{c}(2923)^{0} and Ξc(2939)0\Xi_{c}(2939)^{0}, whose masses and widths are measured to be m(Ξc(2923)0)=2924.5±0.4±1.1MeV,m(Ξc(2939)0)=2938.5±0.9±2.3MeV,Γ(Ξc(2923)0)=0004.8±0.9±1.5MeV,Γ(Ξc(2939)0)=0011.0±1.9±7.5MeV, m(\Xi_{c}(2923)^{0}) = 2924.5 \pm 0.4 \pm 1.1 \,\mathrm{MeV}, \\ m(\Xi_{c}(2939)^{0}) = 2938.5 \pm 0.9 \pm 2.3 \,\mathrm{MeV}, \\ \Gamma(\Xi_{c}(2923)^{0}) = \phantom{000}4.8 \pm 0.9 \pm 1.5 \,\mathrm{MeV},\\ \Gamma(\Xi_{c}(2939)^{0}) = \phantom{00}11.0 \pm 1.9 \pm 7.5 \,\mathrm{MeV}, where the first uncertainties are statistical and the second systematic. The results are consistent with a previous LHCb measurement using a prompt Λc+K\Lambda_{c}^{+} K^{-} sample. Evidence of a new Ξc(2880)0\Xi_{c}(2880)^{0} state is found with a local significance of 3.8σ3.8\,\sigma, whose mass and width are measured to be 2881.8±3.1±8.5MeV2881.8 \pm 3.1 \pm 8.5\,\mathrm{MeV} and 12.4±5.3±5.8MeV12.4 \pm 5.3 \pm 5.8 \,\mathrm{MeV}, respectively. In addition, evidence of a new decay mode Ξc(2790)0Λc+K\Xi_{c}(2790)^{0} \to \Lambda_{c}^{+} K^{-} is found with a significance of 3.7σ3.7\,\sigma. The relative branching fraction of BΛc+ΛˉcKB^{-} \to \Lambda_{c}^{+} \bar{\Lambda}_{c}^{-} K^{-} with respect to the BD+DKB^{-} \to D^{+} D^{-} K^{-} decay is measured to be 2.36±0.11±0.22±0.252.36 \pm 0.11 \pm 0.22 \pm 0.25, where the first uncertainty is statistical, the second systematic and the third originates from the branching fractions of charm hadron decays.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-028.html (LHCb public pages

    The ratios of branching fractions R(D)B(BˉDτνˉτ)/B(BˉDμνˉμ)\mathcal{R}(D^{*})\equiv\mathcal{B}(\bar{B}\to D^{*}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(\bar{B}\to D^{*}\mu^{-}\bar{\nu}_{\mu}) and R(D0)B(BD0τνˉτ)/B(BD0μνˉμ)\mathcal{R}(D^{0})\equiv\mathcal{B}(B^{-}\to D^{0}\tau^{-}\bar{\nu}_{\tau})/\mathcal{B}(B^{-}\to D^{0}\mu^{-}\bar{\nu}_{\mu}) are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb1{ }^{-1} of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode τμντνˉμ\tau^{-}\to\mu^{-}\nu_{\tau}\bar{\nu}_{\mu}. The measured values are R(D)=0.281±0.018±0.024\mathcal{R}(D^{*})=0.281\pm0.018\pm0.024 and R(D0)=0.441±0.060±0.066\mathcal{R}(D^{0})=0.441\pm0.060\pm0.066, where the first uncertainty is statistical and the second is systematic. The correlation between these measurements is ρ=0.43\rho=-0.43. Results are consistent with the current average of these quantities and are at a combined 1.9 standard deviations from the predictions based on lepton flavor universality in the Standard Model.Comment: All figures and tables, along with any supplementary material and additional information, are available at https://cern.ch/lhcbproject/Publications/p/LHCb-PAPER-2022-039.html (LHCb public pages

    Atualmente o mercado de trabalho é composto por profissionais de diferentes faixas etárias convivendo juntos na mesma organização. Para estas diferentes faixas etárias nomeou “geração”, conceito que classifica o conjunto de indivíduos que nasceram em uma mesma época e que têm determinados comportamentos, valores e necessidades. Estas necessidades impactam na motivação e nas perspectivas que cada uma tem sobre seu futuro pessoal e profissional. O objetivo deste trabalho é entender fatores motivacionais que influenciam os trabalhadores de cada geração e verificar quais são as suas expectativas de carreira profissional. Utilizou a pesquisa de campo, com a elaboração de um questionário com questões fechadas de múltipla escolha e uma para comentários. O questionário foi enviado para cento e setenta e oito trabalhadores de diferentes faixas etárias, de algumas empresas na cidade de Bauru/SP. As considerações obtidas sobre a expectativa de carreira profissional foram que as gerações Baby boomers, X e Y em sua maioria querem construir uma carreira sólida na mesma empresa, optando pela estabilidade e fidelidade ao emprego. Já a geração Z, prefere a carreira sem fronteiras, motivados por fatores como a flexibilidade, autonomia e qualidade de vida. Além disso, os resultados apontam que os colaboradores de todas as gerações, em sua maioria, estão satisfeitos com seus empregos atuais e têm pensado no futuro, planejando suas carreiras profissionais. Outra discussão da pesquisa demonstrou que os fatores motivacionais de mais relevância para as gerações foram segurança financeira; qualidade de vida e flexibilidade no trabalho. = Nowadays the labor market is formed by professionals of different age groups living together in the same organization. For these different age groups it was given the name “generation”, concept that classifies the group of people that were born in the same age and that have certain behaviors, values and needs. These needs impacts in the motivation and in the perspectives that each one has about the personal and professional future. The goal of this project is to understand motivational factors that influence the employees of each generation and check what their career expectations are. For this, the methodology used was field research with the elaboration of a questionnaire that contains seventeen closed multiple-choice questions and one question for comments. The questionnaire was delivered personally, or in few cases sent by e-mail to one hundred seventy-eight workers of different age groups of some companies in Bauru/SP. The results presented on the expectation of the career were that the majority of Baby boomers, X and Y generations want to build a solid career in the same company, opting for stability and fidelity of your jobs. The generation Z prefers the career without boundaries motivated by factors such as flexibility, autonomy and quality of life. Furthermore, the results point that the majority of employees of all generations are satisfied with their current jobs and they have been thinking about the future planning their careers. Another discussion of the research showed that the most relevant motivational factors for the generations were financial security, quality of life and flexibility at work
