The association of smoking status with SARS-CoV-2 infection, hospitalization and mortality from COVID-19: a living rapid evidence review with Bayesian meta-analyses (version 7)


Authors: Simons, David; Shahab, Lion; Brown, Jamie; Perski, Olga

Aims To estimate the association of smoking status with rates of (i) infection, (ii) hospitalization, (iii) disease severity and (iv) mortality from SARS-CoV-2/COVID-19 disease. Design Living rapid review of observational and experimental studies with random-effects hierarchical Bayesian meta-analyses. Published articles and pre-prints were identified via MEDLINE and medRxiv. Setting Community or hospital, no restrictions on location. Participants Adults who received a SARS-CoV-2 test or a COVID-19 diagnosis. Measurements Outcomes were SARS-CoV-2 infection, hospitalization, disease severity and mortality stratified by smoking status. Study quality was assessed (i.e. 'good', 'fair' and 'poor'). Findings Version 7 (searches up to 25 August 2020) included 233 studies with 32 'good' and 'fair' quality studies included in meta-analyses. Fifty-seven studies (24.5%) reported current, former and never smoking status. Recorded smoking prevalence among people with COVID-19 was generally lower than national prevalence. Current compared with never smokers were at reduced risk of SARS-CoV-2 infection [relative risk (RR) = 0.74, 95% credible interval (CrI) = 0.58-0.93, tau = 0.41]. Data for former smokers were inconclusive (RR = 1.05, 95% CrI = 0.95-1.17, tau = 0.17), but favoured there being no important association (21% probability of RR >= 1.1). Former compared with never smokers were at somewhat increased risk of hospitalization (RR = 1.20, CrI = 1.03-1.44, tau = 0.17), greater disease severity (RR = 1.52, CrI = 1.13-2.07, tau = 0.29) and mortality (RR = 1.39, 95% CrI = 1.09-1.87, tau = 0.27). Data for current smokers were inconclusive (RR = 1.06, CrI = 0.82-1.35, tau = 0.27; RR = 1.25, CrI = 0.85-1.93, tau = 0.34; RR = 1.22, 95% CrI = 0.78-1.94, tau = 0.49, respectively), but favoured there being no important associations with hospitalization and mortality (35% and 70% probability of RR >= 1.1, respectively) and a small but important association with disease severity (79% probability of RR >= 1.1). Conclusions Compared with never smokers, current smokers appear to be at reduced risk of SARS-CoV-2 infection, while former smokers appear to be at increased risk of hospitalization, increased disease severity and mortality from COVID-19. However, it is uncertain whether these associations are causal.

Impedance spectroscopy analysis and piezoelectric properties of (Na0.5Bi0.5)(0.94)Ba0.06TiO3+0.3wt.% Sm2O3 lead-free ceramics sintered at different conditions

(Na0.5Bi0.5)(0.94)Ba0.06TiO3 + 0.3 wt.% Sm2O3 (named NBT-BT) lead-free piezoelectric ceramics were prepared by normal sintering. The effect of atmosphere sintering on NBT-BT ceramics was investigated through X-ray diffraction, dielectric, ferroelectric and piezoelectric characterizations. Real (Z ') and imaginary (Z '') parts of the complex impedance of the materials were also investigated. Dielectric studies exhibit a diffuse transition phase and are characterized by a temperature and frequency dispersion of permittivity, and this relaxation has been modeled using the modified Curie-Weiss law. The variation of the imaginary part (Z '') of impedance with frequency at various temperatures shows that the Z '' values reach a maxima peak (Z ''(max)). The appearance of single semicircle in the Nyquist plots (Z '' vs Z ') pattern at high temperatures suggests that the electrical process occurring in the material has a relaxation process possibly due to the contribution of bulk material only. It shows that the compound exhibit negative temperature coefficient of resistance (NTCR) type behavior usually found in semiconductors. The bulk resistance of the material decreases with rising temperatures similar to a semiconductor, and the Nyquist plot showed the negative temperature coefficient of resistance (NTCR) character of materials. Also, the frequency-dependent AC conductivity at different temperatures indicated that the conduction process is thermally activated process. The plots of the relaxation times tau(Z)'' and tau(M)'' as a function of temperature follow the Arrhenius law, where a single slope is observed with activation energy values come to near 1.70.
