Open Payments Data Analysis of General and Fellowship-trained Surgeons Receiving Industry General Payments from 2016 to 2020: Payment Disparities and COVID-19 Pandemic Impact.

OBJECTIVE: To characterize industry non-research payments made to general and fellowship-trained surgeons between 2016-2020. BACKGROUND: The Centers for Medicare & Medicaid Services Open Payments Data (OPD) reports industry payments made to physicians related to drugs and medical devices. General payments are those not associated with research. METHODS: OPD data were queried for general and fellowship-trained surgeons who received general payments from 2016 to 2020. Payments' nature, amount, company, covered product, and location were collected. Surgeons' demographics, subspecialty, and leadership roles in hospitals, societies, and editorial boards were evaluated. RESULTS: From 2016 to 2020, 44,700 general and fellowship-trained surgeons were paid $535,425,543 in 1,440,850 general payments. The median payment was $29.18. The most frequent payments were for food and beverage (76.6%) and travel and lodging (15.6%); however, the highest dollar payments were for consulting fees ($93,128,401; 17.4%), education ($88,404,531; 16.5%), royalty or license ($87,471,238; 16.3%), and travel and lodging ($66,333,149; 12.4%). Five companies made half of all payments ($265,654,522; 49.6%): Intuitive Surgical ($128,517,411; 24%), Boston Scientific ($48,094,570; 9%), Edwards Lifesciences ($41,835,544, 7.8%), Medtronic Vascular ($33,607,136; 6.3%), and W. L. Gore & Associates ($16,626,371; 3.1%). Medical devices comprised 74.7% of payments ($399,897,217), followed by drugs and biologicals ($33,945,300; 6.3%). TX, CA, FL, NY, and PA received the most payments; however, the top dollar payments were in CA ($65,702,579; 12.3%), MI ($52,990,904, 9.9%), TX ($39,362,131; 7.4%), MD ($37,611,959; 7%), and FL ($33,417,093, 6.2%). General surgery received the highest total payments ($245,031,174; 45.8%), followed by thoracic surgery ($167,806,514; 31.3%) and vascular surgery ($60,781,266; 11.4%). A total of 10,361 surgeons were paid >$5,000, of which 1,614 were women (15.6%); in this group, men received higher payments than women (means, $53,446 vs. $22,571; P<0.001) and thoracic surgeons received the highest payments (mean, $76,381; NS, P=0.14). A total of 120 surgeons were paid >$500,000 ($203,011,672; 38%) - 5 non-Hispanic white (NHW) women (4.2%) and 82 NHW (68.3%), 24 Asian (20%), 7 Hispanic (5.8%), and 2 Black (1.7%) men; in this group, men received higher payments than women (means, $1,735,570 vs. $684,224), and NHW men received payments double those of other men (means, $2,049,554 vs. $955,368; NS, P=0.087). Among these 120 highly paid surgeons (>$500,000), 55 held hospital and departmental leadership roles, 30 were leaders in surgical societies, 27 authored clinical guidelines, and 16 served on journal editorial boards. During COVID-19, 2020 experienced half the number of payments than the preceding 3 years. CONCLUSIONS: General and fellowship-trained surgeons received substantial industry non-research payments. Highest paid recipients were men. Further work is warranted in assessing how race, gender, and leadership roles influence the nature of industry payments and surgical practice. A significant decline in payments was observed early during the COVID-19 pandemic.

Post-traumatic Stress Disorder and Associated Factors 1 Year After the Beginning of the COVID-19 Pandemic Among Chinese Residents.

Background: By investigating the incidence of post-traumatic stress disorder (PTSD) among residents during a period of low transmission, this study reflects the long-term impact of coronavirus disease 2019 (COVID-19) and identify which categories of residents are more likely to develop PTSD due to an acute infectious disease crisis, facilitating the development of targeted strategies to protect mental health after outbreaks of similar acute infectious diseases in the future. Methods: A cross-sectional survey was conducted in China from 4 to 26 February 2021. A convenience sampling strategy was adopted to recruit participants. Participants were asked to complete the PTSD Checklist for DSM-5 (PCL-5). A multivariable linear stepwise regression analysis model was used to identify which factors were associated with PTSD in residents of China. Results: A total of 2,361 Chinese residents completed the questionnaire. The mean PCL-5 score for the respondents was 13.65 (SD = 8.66), with 219 (9.28%) patients having probable PTSD symptoms. Respondents who were female (ß = 0.038), had a relative or friend who had contracted COVID-19 (ß = 0.041), and had poor health (ß = 0.184) had higher PCL-5 scores, while the population aged over 60 years (ß = -0.063), who agreed that COVID-19 information was released in a timely manner (ß = -0.347), who had experienced a relatively limited impact of COVID-19 on their life (ß = -0.069), and who agreed that the local prevention initiatives were sophisticated (ß = -0.165) had lower PTSD scores. Conclusions: Outbreaks of acute infectious diseases can have long-term psychological health effects in the general population. In addition, health policy makers need to be concerned about and implement measures to support the mental health of vulnerable groups.

Crystal structures of the SARS-CoV-2 nucleocapsid protein C-terminal domain and development of nucleocapsid-targeting nanobodies.

The ongoing outbreak of COVID-19 caused by SARS-CoV-2 has resulted in a serious public health threat globally. Nucleocapsid protein is a major structural protein of SARS-CoV-2 that plays important roles in the viral RNA packing, replication, assembly, and infection. Here, we report two crystal structures of nucleocapsid protein C-terminal domain (CTD) at resolutions of 2.0 Å and 3.1 Å, respectively. These two structures, crystallized under different conditions, contain 2 and 12 CTDs in asymmetric unit, respectively. Interestingly, despite different crystal packing, both structures show a similar dimeric form as the smallest unit, consistent with its solution form measured by the size-exclusion chromatography, suggesting an important role of CTD in the dimerization of nucleocapsid proteins. By analyzing the surface charge distribution, we identified a stretch of positively charged residues between Lys257 and Arg262 that are involved in RNA-binding. Through screening a single-domain antibodies (sdAbs) library, we identified four sdAbs targeting different regions of nucleocapsid protein with high affinities that have future potential to be used in viral detection and therapeutic purposes.

Assessing the COVID-19 vaccine hesitancy in the Chinese adults using a generalized vaccine hesitancy survey instrument.

The objectives of this study were to determine coronavirus disease 2019 (COVID-19) vaccination hesitancy and influencing factors in China, while broadening the applicability of the Vaccine Hesitancy Scale (VHS). A cross-sectional survey was conducted in China from 4th to 26th February 2021. Convenience sampling method was adopted to recruit participants. A total of 2,361 residents filled out the questionnaire. Confirmatory factor analysis was used on the validation set to confirm the latent structure that resulted from the exploratory factor analysis, which was conducted on the construction set. Multiple linear regression model analyses were used to identify significant associations between the identified the revised version of VHS subscales and hypothesized explanatory variables. Two subscales were identified within the VHS through data analysis, including "lack of confidence in the need for vaccines" and "aversion to the risk of side effects." The results indicated that the hesitancy of the participants in our sample was both driven the two mainly aspects. In addition, more than 40% of the participants expressed hesitation in half of the items in VHS. This study characterized COVID-19 vaccine hesitancy in China, and identified disparities in vaccine hesitancy by socio-demographic groups and knowledge about the vaccine. Knowledge of the vaccine was statistically linked to respondents' answers to the clustered 'lack of confidence' and 'risks perception' items. Our results characterize Chinese citizens' COVID-19 vaccine concerns and will inform targeted health communications.

Post-lockdown SARS-CoV-2 nucleic acid screening in nearly ten million residents of Wuhan, China.

Stringent COVID-19 control measures were imposed in Wuhan between January 23 and April 8, 2020. Estimates of the prevalence of infection following the release of restrictions could inform post-lockdown pandemic management. Here, we describe a city-wide SARS-CoV-2 nucleic acid screening programme between May 14 and June 1, 2020 in Wuhan. All city residents aged six years or older were eligible and 9,899,828 (92.9%) participated. No new symptomatic cases and 300 asymptomatic cases (detection rate 0.303/10,000, 95% CI 0.270-0.339/10,000) were identified. There were no positive tests amongst 1,174 close contacts of asymptomatic cases. 107 of 34,424 previously recovered COVID-19 patients tested positive again (re-positive rate 0.31%, 95% CI 0.423-0.574%). The prevalence of SARS-CoV-2 infection in Wuhan was therefore very low five to eight weeks after the end of lockdown.
