Abstract
Previous research about organizational citizenship behavior (OCB) and counterproductive work behavior (CWB) has produced contradictory results. Drawing from the conservation of resources (COR) theory, the present study tries to explain the contradictory findings by examining the curvilinear relationship between OCB and CWB. Using data collected at three time points from 426 employees and 110 supervisors in Chinese companies, data analysis shows that OCB has an inverted U-shaped relationship with CWB. The results also demonstrate that citizenship fatigue mediates the relationship between OCB and CWB, perceived organizational support (POS) moderates the relationship between OCB and citizenship fatigue. In addition, POS moderates the mediating effect of citizenship fatigue in the inverted U-shaped curvilinear relationship between OCB and CWB. This mediating effect is stronger under conditions of low POS than high POS. The findings present a complementary explanation of the conflicting relationships between OCB and CWB.

Abstract
Temperature-dependent dynamic structure factors S(Q, ω) for liquid water have been calculated using a composite model, which is based on the decoupling approximation of the mean square displacement of the water molecules into diffusion and solid-like vibrational parts. The solid-like vibrational part Svib(Q, ω) is calculated with the phonon expansion method established in the framework of the incoherent Gaussian approximation. The diffusion part Sdiff(Q, ω) relies on the Egelstaff-Schofield translational diffusion model corrected for jump diffusions and rotational diffusions with the Singwi-Sjölander random model and Sears expansion, respectively. Systematics of the model parameters as a function of temperature were deduced from quasi-elastic neutron scattering data analysis reported in the literature and from molecular dynamics (MD) simulations relying on the TIP4P/2005f model. The resulting S(Q, ω) values are confronted by means of Monte Carlo simulations to inelastic neutron scattering data measured with IN4, IN5, and IN6 time-of-flight spectrometers of the Institut Laue-Langevin (ILL) (Grenoble, France). A modest range of temperatures (283-494 K) has been investigated with neutron wavelengths corresponding to incident neutron energies ranging from 0.57 to 67.6 meV. The neutron-weighted multiphonon spectra deduced from the ILL data indicate a slight overestimation by the MD simulations of the frequency shift and broadening of the librational band. The descriptive power of the composite model was suited for improving the comparison to experiments via Bayesian updating of prior model parameters inferred from MD simulations. The reported posterior temperature-dependent densities of state of hydrogen in H2O would represent valuable insights for studying the collective coupling interactions in the water molecule between the inter- and intramolecular degrees of freedom.

Abstract
In this study, we investigate the coping response of individuals who are being gossiped about. Drawing on face research and affective events theory, we propose that employees who are targets of negative gossip will actively respond to the gossip about them via engagement in negative gossip themselves. The findings showed that negative workplace gossip stimulated fear of losing face and led to subsequent behavioral responses, namely, engaging in negative gossip. Moreover, self-monitoring, as a moderating mechanism, mitigated the negative impacts of negative workplace gossip on the targets. We discuss theoretical implications for gossip research and note its important practical implications.

Abstract
Background:AWARE is a real-world evidence-based (RWE) study evaluating the safety and efficacy of IV golimumab (GLM) and infliximab (IFX) in adults with RA.Objectives:Evaluate safety and efficacy of IV GLM and IFX in elderly AWARE participants.Methods:AWARE, a prospective non-interventional study (88 US sites), enrolled patients (pts) initiating either IV GLM or IFX. Pt management was at the discretion of treating rheumatologists. In a post hoc analysis, pts were grouped by age (<65/≥65/≥75 yrs). Adverse events (AEs) were collected through the Week (W) 52 database lock (DBL; completed W52 or discontinued study) and at the end-of-study DBL (W104). The primary endpoint was proportion of pts with ≥1 infusion reaction through W52. Change from baseline in Clinical Disease Activity Index (CDAI) scores at Months 6 and 12 were secondary endpoints evaluated in bionaïve pts, including those with IFX dose escalation.Results:1270 pts were enrolled (685 IV GLM; 585 IFX). 1047 (82%) pts were female; mean age was 60 yrs (57% <65 yrs, 43% ≥65 yrs, and 7% ≥75 yrs). Mean disease durations were 9 yrs (IV GLM) and 7 yrs (IFX). Comorbidities were generally similar between IV GLM and IFX groups but more common among pts ≥65 vs <65 yrs. Through W52, 66% of IV GLM pts and 62% of IFX pts discontinued the study. Discontinuation due to lack of efficacy was generally similar across age groups within treatment groups, although somewhat higher for IV GLM (29%) vs IFX (19%). For both treatments, AEs and discontinuations due to AE through W52 were more common in pts ≥65 vs <65 yrs (Table 1). Consistent with general trends observed in elderly individuals,1 rates of serious AEs (SAEs) and serious infections increased with age for both IV GLM and IFX; however, increases were more notable in IFX- than IV GLM-treated pts ≥65 yrs. The incidence of serious infections was highest in pts ≥75 yrs for both treatments, although small sample size may limit data interpretation. No increase in opportunistic infections, including Varicella, was observed in pts ≥65 vs <65 yrs. Infusion reactions were more common in pts <65 yrs in both treatment groups, and more prevalent in IFX- than IV GLM-treated pts within each age group through W52. Generally similar safety results were seen between W52 and W104 for each treatment group (data not shown). Both IV GLM and IFX in bionaïve pts showed improvement in CDAI scores across age groups, which was maintained over time (Figure 1).Table 1.% of pts with ≥1 AE through W52 DBLIV GLMIFX<65 yrs≥65 yrs≥75 yrs<65 yrs≥65 yrs≥75 yrsPatients, n3513349137021546Discontinued due to AE8.5%12.6%16.5%15.1%17.7%21.7%AE52.4%58.4%57.1%63.5%66.5%71.7%Most common AEs (≥5% of pts in either treatment group)Nausea3.7%3.3%3.3%8.4%6.0%2.2%Worsening of RA5.4%4.5%3.3%7.3%7.0%4.3%Upper respiratory tract infection5.7%5.1%4.4%6.2%5.6%2.2%Pruritis1.4%2.4%3.3%6.8%2.8%2.2%Sinusitis7.1%3.3%0%3.8%3.7%2.2%Urinary tract infection4.8%5.1%5.5%4.3%5.1%6.5%SAE7.7%16.8%20.9%9.7%18.6%26.1%Infection30.5%27.2%27.5%32.2%28.8%32.6%Serious infection3.7%6.3%7.7%3.5%7.9%15.2%Neoplasms benign, malignant and unspecified0.6%2.7%1.1%0.8%2.3%6.5%Latent tuberculosis0.3%0%00.3%0%0%Opportunistic infection1.4%1.8%4.4%1.9%1.4%4.3%Infusion reaction5.1%2.7%1.1%17.3%8.8%8.7%Death0.3%2.4%2.2%0%2.3%6.5%Conclusion:Elderly RA pts receiving IV GLM or IFX in this RWE study demonstrated similar safety and efficacy as reported in Phase 3 trials.2,3 The higher rates of AEs, discontinuations due to AE, and SAEs (mainly serious infections) observed in pts ≥65 yrs are in line with increased safety events seen in elderly vs younger individuals in the general population.

Abstract
Background:AWARE is a phase-4 observational study designed to provide real-world assessment of Golimumab (GLM) IV & infliximab (IFX) in patients (pts) with rheumatoid arthritis (RA).Objectives:To assess patient-reported aspects of social, mental, & physical health through the 8th infusion (≈1 year of treatment) using Patient Reported Outcomes Measurement Information System (PROMIS), a validated, disease-agnostic set of health assessment instruments.Methods:AWARE enrolled 1270 RA pts initiating treatment with GLM/IFX. The 52 week analysis set included pts with ≥1-year treatment or those discontinued and, while enrolled, completed PROMIS-29 or PROMIS short form (SF) questionnaires. PROMIS instruments were administered at baseline & prior to infusions 2, 5, & 8. The raw score was converted into a standardized T-score with a mean of 50 and SD of 10.Results:At baseline, treatment groups were balanced on demographics & medical characteristics. Most pts were white (87.0% GLM, 86.2% IFX) & female (83.4% GLM, 82.4% IFX). Mean ages were 58.5 ±12.96 years for GLM & 59.6 ±13.24 years for IFX. Overall, 35.3% GLM & 42.9% IFX pts were bio-naïve. The proportion of GLM & IFX pts with prior exposure to 1 or 2 biologics was similar; however, 20.1% GLM pts vs 10.8% IFX pts had exposure to ≥3 biologics. Methotrexate use was similar between GLM (76.4%) & IFX pts (75.0%). Based on mean PROMIS T-scores at baseline (Table 1), Fatigue, Pain Interference, & Physical Function domains approached or exceeded 1 SD worse than those of general US population. Through the 8th infusion, GLM- & IFX-treated pts achieved meaningful improvement based on mean changes from baseline in most PROMIS-29 domains & respective SFs with no significant difference between GLM and IFX. The percentage of GLM or IFX pts with improvements of ≥3, ≥5, or ≥10 units change in T-scores increased from infusion 2 through infusion 8.Conclusion:RA pts treated with GLM or IFX achieved comparable improvements across PROMIS-assessed social, mental, & physical health. PROMIS-29 was able to detect change to subsequent anti-tumor necrosis factor-α therapies.Table 1.Mean (SD) Change from Baseline PROMIS-29 Domain and Short Form T-Scores: 52 Week Analysis SetGLMIFXLSM difference (95% CI)*Anxiety (4-item)N=6N=570Baseline53.4 (10.13)54.6 (10.53)Change from baseline at infusion 8N=223 -2.6 (8.10)N=286-3.7 (7.86)-0.29 (-1.54, 0.97)Depression (4-item)BaselineN=67451.9 (9.83)N=57452.5 (10.21)Change from baseline at infusion 8N=225-2.1 (7.56)N=287-2.3 (7.89)0.49 (-0.72, 1.70)Fatigue (4-item)BaselineN=67158.4 (9.91)N=57459.4 (9.99)Change from baseline at infusion 8N=225-3.4 (8.72)N=281-3.1 (7.77)0.69 (-0.64, 2.03)Short form Fatigue 7aBaselineN=68159.1 (8.51)N=57659.7 (8.25)Change from baseline at infusion 8N=228-3.2 (7.40)N=287-2.4 (6.35)1.01 (-0.11, 2.14)Pain interference (4-item)BaselineN=67963.0 (7.56)N=57463.9 (7.80)Change from baseline at infusion 8N=227-4.2 (8.23)N=284-3.1 (7.77)1.84 (0.55, 3.13)Short form Pain interference 6bBaselineN=68061.9 (7.45)N=57662.8 (7.54)Change from baseline at infusion 8N=228-3.8 (7.88)N=287-3.2 (6.67)1.31 (0.15, 2.48)Physical function (4-item)BaselineN=67838.2 (6.79)N=57138.0 (6.90)Change from baseline at infusion 8N=2242.2 (5.64)N=2831.9 (5.85)-0.76 (-1.73, 0.21)Sleep disturbance (4-item)BaselineN=67154.6 (8.72)N=569N=55.5 (8.61)Change from baseline at infusion 8N=221-1.4 (7.45)N=281-1.7 (7.61)0.23 (-0.96, 1.42)Social participation (4-item)BaselineN=67343.7 (8.40)N=57442.9 (8.77)Change from baseline at infusion 8N=2253.2 (8.15)N=2833.4 (7.48)-0.10 (-1.36, 1.16)*Least squares mean (LSM) difference & confidence interval (CI) are based on analysis of covariance controlling for baseline PROMIS score using inverse probability of treatment weighted propensity score.Disclosure of Interests:Clifton Bingham Consultant of: AbbVie, BMS, Eli Lilly, Gilead, Janssen, Pfizer, Regeneron/Sanofi, Grant/research support from: Bristol-Myers Squibb, Shelly Kafka Employee of: Janssen Research & Development, LLC, Shawn Black Employee of: Janssen Research & Development, LLC, Stephen Xu Employee of: Janssen Research & Development, LLC, Wayne Langholff Employee of: Janssen Research & Development, LLC, Jeffrey Curtis Consultant of: AbbVie, Amgen, Bristol-Myers Squibb, Corrona, Janssen, Lilly, Myriad, Pfizer, Regeneron, Roche, UCB, Grant/research support from: AbbVie, Amgen, Bristol-Myers Squibb, Corrona, Janssen, Lilly, Myriad, Pfizer, Regeneron, Roche, UCB

Abstract
Background:Guselkumab (GUS), an anti-interleukin-23p19-subunit monoclonal antibody, demonstrated efficacy vs placebo (PBO) in achieving American College of Rheumatology 20% improvement (ACR20) response in patients (pts) with active psoriatic arthritis (PsA) in two phase 3 trials, DISCOVER-1 & 2.1,2Objectives:To assess the differential treatment effects of GUS across individual components of ACR response in PsA pts participating in the DISCOVER-1 & 2 trials.Methods:In DISCOVER-1 & 2, 1120 pts were randomized & treated with GUS 100 mg every 4 weeks (Q4W; N=373); GUS 100 mg at Week (W)0 and W4, then Q8W (N=375); or matching PBO (N=372). Pts were evaluated by independent joint assessors at study visits. ACR20 response is defined as ≥20% improvement from baseline in both tender joint count (0-68 [TJC68]) and swollen joint count (0-66 [SJC66]) and ≥20% improvement from baseline in ≥3 of 5 assessments: Patient Assessment of Pain [Pt Pain], Patient Assessment of Global Disease Activity (arthritis) [PtGA], Physician Assessment of Global Disease Activity [PGA], Patient assessment of physical function as measured by Disability Index of the Health Assessment Questionnaire (HAQ-DI), and C-reactive protein (CRP). For each ACR component, achievement of ≥20% improvement from baseline was assessed over time through W24 for the combined (Q4W+Q8W) GUS groups, and median time to onset of treatment effect was determined with Kaplan-Meier curves by randomized group.Results:Median time to response for all components except SJC66 occurred earlier with GUS than PBO. Time to onset of ACR20 treatment effect is shown in Figure 1. CRP data show 56% of GUS-treated pts had diminution of systemic inflammation by W4 (Table 1). Reduction in systemic inflammation was accompanied or rapidly followed by GUS-related improvement in both PtGA and PGA (median W4-8). Although SJC66/TJC68 data showed similar patterns, there was also a high PBO response (data not shown). Consistent with early reductions in systemic inflammation, 48-61% of GUS-treated pts had ≥20% improvement in TJC68/SJC66/PGA at W4 (Table 1), and 45-48% had ≥20% improvement in HAQ-DI, PtGA, and Pt Pain by W8. By W24, >80% of GUS-treated pts had ≥20% improvement in SJC66/TJC68/PGA, followed by 63-64% with this degree of improvement in PtGA, CRP, and Pt Pain, and 57% for HAQ-DI.Conclusion:GUS demonstrated ACR20 improvements with separation from PBO in ACR components as early as W4, which is consistent with reduced inflammation by GUS and prior serological studies.3 At early study time points, both pts and physicians were able to discern improvements in signs and symptoms of arthritis that rapidly followed reductions in systemic inflammation (CRP). The predominant drivers of ACR20 response rates at W24 in GUS pts were SJC66/TJC68/PGA.References:[1]Deodhar A et al. Lancet. 2020;395:1115-25[2]Mease P et al.

Abstract
Background:The GO-ALIVE study assessed efficacy and safety of intravenous golimumab (IV GLM) in patients (pts) with ankylosing spondylitis (AS).1,2Objectives:In this post hoc analysis, we assessed IV GLM efficacy and safety in AS pts with early disease (ED) vs late disease (LD) based on pt-reported duration of inflammatory back pain (IBP).Methods:In this Phase 3, double-blind, placebo (PBO)-controlled trial, pts with active AS were randomized (1:1) to receive IV GLM 2 mg/kg at Week (W) 0, W4, then Q8W or PBO at W0, W4, and W12 with crossover to IV GLM at W16, W20, then Q8W through 52. The primary endpoint was achievement of SpondyloArthritis International Society 20% improvement response (ASAS 20) at W16. In this post hoc analysis, 208 pts were grouped into quartiles based on self-reported duration of IBP symptoms. Efficacy and safety in 60 pts with ED (1st quartile) were compared with 52 pts with LD (4th quartile).Results:For the overall study population, mean duration of IBP symptoms was 10.9 yr and mean time since diagnosis was 5.5 yr. For ED pts, the mean duration of IBP symptoms ranged from 2.3 yr (IV GLM) to 2.6 yr (PBO), and for LD pts ranged from 23.5 yr (IV GLM) to 24.4 yr (PBO). At W16, ASAS 20 was achieved by 72% IV GLM vs 32% PBO pts with ED and by 67% IV GLM vs 21% PBO pts with LD. Pts with ED had numerically better response than those with LD in Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), and across more stringent endpoints, including ASAS 40, Bath Ankylosing Spondylitis Disease Activity Index 50% improvement (BASDAI 50), and Ankylosing Spondylitis Disease Activity Score (ASDAS) inactive disease and major improvement (Table 1). Response rates at W16 among IV GLM-treated pts were generally consistent through 1 year in both ED and LD subgroups; also in ED and LD subgroups, pts crossing over to IV GLM at W16 demonstrated response at W52 consistent with pts who started IV GLM at W0. At W16, improvements in enthesitis score were similar for pts with ED (mean change -2.9 for IV GLM vs 0.1 for PBO) and LD (mean change -2.5 for IV GLM vs 0.6 for PBO); improvements were maintained at W52 for ED and LD pts. Treatment-emergent adverse events and serious adverse events through 1 year were 46% and 3% for pts with ED compared with 61% and 2% for pts with LD, respectively.Conclusion:While IV GLM provided clinically meaningful improvements in signs and symptoms of AS in pts regardless of disease duration, response generally appeared numerically better in pts with ED than in pts with LD. This supports the principle of prompt diagnosis and early treatment.References:[1]Deodhar A, et al. J Rheumatol. 2018;45:341-348.[2]Reveille J, et al.

Abstract
Background:The monoclonal antibody guselkumab (GUS; anti- IL-23p19-subunit) is approved to treat psoriatic arthritis (PsA). Post hoc analyses of DISCOVER-1&2 suggested that GUS may be effective in improving symptoms of axial manifestation of PsA.Objectives:Evaluate the efficacy of GUS across components of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in improving symptoms of axial manifestations of active PsA patients (pts) using data from Phase 3, randomized, placebo (PBO)-controlled studies.Methods:DISCOVER-1&2 enrolled pts with active PsA; pts were randomized to subcutaneous injections of guselkumab 100 mg every 4 weeks (Q4W) or at Wk0, 4, and Q8W, or PBO. These post hoc analyses included pts who were identified by the investigator as having axial symptoms and sacroiliitis (prior X-ray or MRI or screening X-ray). BASDAI scores were assessed at Wks 0, 8, 16, 24, and 52. Mean BASDAI component scores through Wk52 are reported by treatment group. Pooled data from the two studies are reported. Mean BASDAI component scores are reported using observed data; total BASDAI scores with missing components were set to missing. The proportion of pts achieving ≥50% improvement in BASDAI (BASDAI 50) was also determined; pts with missing data or who met the treatment failure criteria (discontinued study agent or used prohibited medications) were considered nonresponders at all subsequent timepoints.Results:These analyses included 312 pts from DISCOVER-1&2 (103 GUS Q4W, 91 GUS Q8W, 118 PBO); mean total BASDAI scores at Wk0 were 6.4, 6.5, and 6.6, respectively. Demographics and mean baseline BASDAI component scores (ie, fatigue, spinal pain, joint pain, enthesitis, qualitative morning stiffness, and quantitative morning stiffness) were similar across treatment groups (Table 1). In comparison with the total study population, this subgroup of pts had a higher mean C-reactive protein level at baseline and a higher proportion of pts with enthesitis and included a slightly higher proportion of males. Mean scores for all six BASDAI components, including spinal pain, decreased through Wk24 in GUS-treated pts, with separation from PBO observed as early as Wk8; improvements were maintained at Wk52. At Wk24, BASDAI 50 response rates were higher in the Q4W and Q8W groups vs PBO (38% and 40% vs 19%).1 At WK52, mean BASDAI component scores for PBO pts who crossed over to GUS Q4W at Wk24 were similar to those for pts who were randomized to GUS.2 A similar trend was observed for BASDAI50 response.Conclusion:Among PsA pts with axial symptoms and sacroiliitis (via investigator-confirmed imaging) in the DISCOVER-1&2 trials, GUS treatment resulted in lower mean scores for all six BASDAI components compared with PBO as early as Wk 8 and through Wk24, with mean scores maintained at Wk52.References:[1]Helliwell P, et al.

Abstract
Regional warming and atmospheric ozone (O3 ) pollution are two of the most important environmental issues, and commonly coexist in many areas. Both factors have an intense impact on plants. However, little information is available on the combined and interactive effects of air warming and elevated O3 concentrations on physiological characteristics of plants. To explore this issue, we studied variations in growth, photosynthesis and physiological characteristics of leaves of Acer ginnala seedlings exposed to control (ambient temperature and O3 ), increasing air temperature (ambient temperature + 2 °C), elevated O3 (ambient O3 concentration + 40 ppb) and a combination of the two abiotic factors at different phenological stages by using open-top chambers. The results showed that increasing air temperature had no significant effect on growth, but increased photosynthesis and antioxidant enzyme activity at the leaf unfolding and defoliation stages. In contrast, elevated O3 decreased growth and photosynthesis and caused oxidative stress injury in A. ginnala leaves at each phenological stage. The combination of increasing air temperature and elevated O3 improved growth and net photosynthetic rates of tested plants and alleviated the oxidative stress compared to O3 alone. Our findings demonstrated that moderate warming was beneficial to A. ginnala at leaf unfolding and defoliation stages, and alleviated the adverse effects of O3 stress on growth, photosynthesis and the antioxidant system. These results will provide a theoretical reference and scientific basis for the adaptation and response of A. ginnala under regional air warming and atmospheric O3 pollution.

Abstract
C-type lectins (CTLs) are a superfamily of proteins found in almost all vertebrates and invertebrates. They play an important role in innate immune defences, development and epidermal structure. Here, a CTL with one carbohydrate-recognition domain containing a highly conserved Gln-Pro-Asp (QPD) motif was identified in Tribolium castaneum and given the name TcCTL5. Spatiotemporal analyses showed that Tcctl5 was highly expressed in the late pupa stage and mainly existed in the central nervous system and haemolymph. The transcript level of Tcctl5 was prominently induced after bacterial infection. Recombinant TcCTL5 proteins (rTcCTL5) were found to bind to lipopolysaccharide, peptidoglycan and tested bacteria and induce microbial agglutination in the presence of Ca2+ . Interestingly, when Tcctl5 was knocked down, the transcript level of antimicrobial peptides (AMPs) (attacin1, defensins3, coleoptericin1 and cecropins3) was prominently downregulated after induction with Gram-negative Escherichia coli. More interestingly, Tcctl5 was knocked down, leading to increased mortality and loss of locomotor activity, which exhibited less travel distances among early adults. These results demonstrate that Tcctl5 plays an important role in the innate immune reaction and the movement of T. castaneum. Thus, it may represent an alternative molecular target for pest control and thus reduce the use of pesticides in agricultural production.

Abstract
OBJECTIVE With the epidemic of coronavirus disease 2019 (COVID-19), the healthcare workers (HCWs) require proper respiratory personal protective equipment (rPPE) against viral respiratory infectious diseases (VRIDs). It is necessary to evaluate which type of mask and manner of wearing is the best suitable rPPE for preventing the VRID. STUDY DESIGN A Bayesian network meta-analysis was performed to comprehensively analyze the protective efficacy of various rPPE. METHODS This network meta-analysis protocol was registered in an international prospective register of systematic reviews (CRD42020179489). Electronic databases were searched for cluster randomized control trials (RCTs) of comparing the effectiveness of rPPE and wearing manner in preventing HCWs from VRID. The primary outcome was the incidence of laboratory-confirmed viral respiratory infection reported as an odds ratio (OR) with the associated 95% credibility interval (CrI). The secondary outcome was the incidence of clinical respiratory illness (CRI) reported as an OR with the associated 95% CrI. Surface under the cumulative ranking curve analysis (SUCRA) provided a ranking of each rPPE according to the primary outcome and the secondary outcome as data supplement. RESULTS Six studies encompassing 12,265 HCWs were included. In terms of the incidence of laboratory-confirmed viral respiratory infection, the continuous wearing of N95 respirators (network OR, 0.48; 95% CrI: 0.27 to 0.86; SUCRA score, 85.4) showed more effective than the control group. However, in terms of reducing the incidence of CRI, there was no rPPE showing superior protective effectiveness. CONCLUSIONS There are significant differences in preventive efficacy among current rPPE. Our result suggests that continuous wearing of N95 respirators on the whole shift can serve as the best preventive rPPE for HCWs from the VRID.
