2%) patients with at least one PSMA-FDG+ lesion. The prostate-specific antigen (PSA) and Gleason score were both higher in the patients with PSMA-FDG+ lesions than in those without PSMA-FDG+ lesions (P = 0.04 and P less then 0.001, respectively). Multivariate regression analysis showed that the Gleason score (≥8) and PSA (≥7.9 ng/mL) were associated with the detection rate of patients who had PSMA-FDG+ lesions (P = 0.01 and P = 0.04, respectively). The incidences of having PSMA-FDG+ lesions in low-probability (Gleason score less then 8 and PSA less then 7.9 ng/mL), medium-probability (Gleason score≥8 and PSA less then 7.9 ng/mL or Gleason score less then 8 and PSA≥7.9 ng/mL), and high-probability (Gleason score≥8 and PSA≥7.9 ng/mL) groups were 0%, 21.7%, and 61.5%, respectively (P less then 0.001). Conclusion Gleason score and PSA are significant predictors for PSMA-FDG+ lesions, and CRPC patients with high Gleason score and PSA may benefit from additional 18F-FDG PET/CT.With hundreds of millions of coronavirus disease 2019 (COVID-19) mRNA-based vaccine doses planned to be delivered worldwide in the upcoming months, it is important to recognize positron emission tomography with computed tomography (PET/CT) findings in recently vaccinated immunocompetent or immunocompromised patients. We aimed to assess PET/CT uptake in the deltoid muscle and axillary lymph nodes of patients that received a COVID-19 mRNA-based vaccine, and to evaluate its association with patients’ age and immune status. Methods All consecutive adult subjects undergoing PET/CT scans with any radiotracer at our center during the first month of a national COVID-19 vaccination rollout (between 23 December 2020 and January 27, 2021) were included. Data regarding clinical status, laterality and time interval from recent COVID-19 mRNA vaccination was prospectively collected and retrospectively analyzed, and correlated with deltoid muscle and axillary lymph nodes uptake. Results Of 426 eligible, recently vaccinated, t’s immune response to the vaccine.Background Functional/molecular imaging characteristics of ischemic ventricular tachycardia (VT) substrate are incompletely understood. Objective Compare regional 18F-FDG – PET tracer uptake with detailed electroanatomic maps (EAM) in a more extensive series of post-infarction VT patients to define metabolic properties of the VT substrate/successful ablation sites. Methods 3D metabolic left ventricular (LV) reconstructions were created from perfusion-normalized 18F-FDG images in consecutive patients undergoing VT ablation. Metabolic defects were defined as severe (1.5mV) were seen in 21% (n = 12) harboring VT channel/exit sites in 41% of patients. Conclusion Abnormal 18F-FDG uptake categories can be detected using incremental 3D step-up reconstructions. They predicted decreasing bipolar voltages and VT channel/exit sites in ~90%. Additionally, functional imaging allowed detecting novel molecular tissue characteristics within the ischemic VT substrate such as metabolic channels, RTA, and MVM demonstrating intra-substrate heterogeneity and providing possible targets for imaging-guided ablation.With almost no community-transmitted cases and without any complete lockdown throughout 2020, Taiwan is one of very few countries worldwide that has recorded minimal impact from the COVID-19 pandemic attack. This is despite being only 130 km from China and having frequent business communications with that country, where COVID-19 first emerged. At the end of December 2020, Taiwan had recorded just 873 cases and 7 deaths, in a country of around 24 million people. How to determine the effectiveness of public health policies is an important issue that must be resolved, especially in those countries that have experienced few cases of community-transmitted COVID-19. Our analysis of epidemiological data in Taiwan relating to influenza-like illness (ILI), enterovirus and diarrhoea from the past 3 years reveals dramatic reductions in the incidence of ILI and enterovirus in 2020, compared with 2018 and 2019. These reductions occurred within 2 weeks of the government issuing public health policies for COVID-19 and indicate that such policies can effectively reduce infectious diseases overall. In contrast, no such reduction in ILI activity was observed in 2020 after the first COVID-19 case was reported in the USA. We suggest that infectious diseases data can be used to inform effective public health policies needed to break the transmission chain of COVID-19 and that ongoing monitoring of infectious diseases data can provide confidence about nationwide health.

While inequalities in oral health are documented, little is known about the extent to which they are attributable to potentially modifiable factors. We examined the role of behavioural and dental attendance pathways in explaining oral health inequalities among adults in England, Wales and Northern Ireland.

Using nationally representative data, we analysed inequalities in self-rated oral health and number of natural teeth. Highest educational attainment, equivalised household income and occupational social class were used to derive a latent socioeconomic position (SEP) variable. Pathways were dental attendance and behaviours (smoking and oral hygiene). We used structural equation modelling to test the hypothesis that SEP influences oral health directly and also indirectly via dental attendance and behavioural pathways.

Lower SEP was directly associated with fewer natural teeth and worse self-rated oral health (standardised path coefficients, -0.21 (SE=0.01) and -0.10 (SE=0.01), respectively). Hesperadin clinical trial We also found significant indirect effects via behavioural factors for both outcomes and via dental attendance primarily for self-rated oral health. While the standardised parameters of total effects were similar between the two outcomes, for number of teeth, the estimated effect of SEP was mostly direct while for self-rated oral health, it was almost equally split between direct and indirect effects.

Reducing inequalities in dental attendance and health behaviours is necessary but not sufficient to tackle socioeconomic inequalities in oral health.
