Background
Kidney transplant recipients are at risk for a severe course of COVID-19 with a high mortality rate. A considerable number of patients remains without a satisfactory serological response after the baseline and adjuvant SARS-CoV-2 vaccination schedule.Methods
In this prospective, randomized study, we evaluated the efficacy and safety of one and two booster doses of mRNA vaccines (either mRNA-1273 or BNT162b2) in 125 COVID-19 naive, adult kidney transplant recipients who showed an insufficient humoral response (SARS-CoV-2 IgG <10 AU/ml) to the previous 2-dose vaccination schedule. The primary outcome was the difference in the rate of a positive antibody response (SARS-CoV-2 IgG ≥10 AU/ml) between one and two booster doses at 1 month after the final booster dose.Results
A positive humoral response was observed in 36 (62%) patients receiving two booster doses and in 28 (44%) patients receiving one booster dose (odds ratio [OR], 2.10, 95% confidence interval [CI], 1.02–4.34, p = .043). Moreover, median SARS-CoV-2 IgG levels were higher with two booster doses (p = .009). The number of patients with positive virus neutralizing antibody (VNA) levels was numerically higher with two booster doses compared to one booster dose, but without statistical significance (66% vs. 50%, p = .084). There was no significant difference in positive seroconversions rate and antibody levels between mRNA-1273 and BNT162b2.Conclusion
A higher number of kidney transplant recipients achieved a positive antibody response after two booster doses compared to one booster dose.

Background: Venous thromboembolism (VTE)—including deep vein thrombosis, pulmonary embolism, and cerebral venous sinus thrombosis (CVST)—may occur early after vaccination against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We sought to describe the site, clinical characteristics, and outcomes of VTE after vaccination against SARS-CoV-2. Methods: In a prospective study using the Registro Informatizado de Enfermedad TromboEmbólica (RIETE) platform, patients with VTE 4–30 days after vaccination against SARS-CoV-2 (1 February 2021 through 30 April 2021) were included. VTE patients recruited from the same centers into RIETE in the same months in 2018–2019 were selected as the reference group. All-cause mortality and major bleeding were the main study outcomes. Results: As of 30 April 2020, 102 patients with post-vaccination VTEs had been identified (28 after adenovirus-based vaccination [ChAdOx1 nCov-19; AstraZeneca] and 74 after mRNA-based vaccination [mRNA-1273; Moderna, and BNT162b2; Pfizer]). Compared with 911 historical controls, patients with VTE after adenovirus-based vaccination more frequently had CVST (10.7% vs. 0.4%, p < 0.001) or thrombosis at multiple sites (17.9% vs. 1.3%, p < 0.001), more frequently had thrombocytopenia (40.7% vs. 14.7%, p < 0.001), and had higher 14-day mortality (14.3% vs. 0.7%; odds ratio [OR]: 25.1; 95% confidence interval [CI]: 6.7–94.9) and major bleeding rates (10.3% vs. 1.0%, OR: 12.03, 95% CI: 3.07–47.13). The site of thrombosis, accompanying thrombocytopenia, and 14-day mortality rates were not significantly different for patients with VTE after mRNA-based vaccination, compared with historical controls. Conclusions: Compared with historical controls, VTE after adenovirus-based vaccination against SARS-CoV-2 is accompanied by thrombocytopenia, occurs in unusual sites, and is associated with worse clinical outcomes. 相似文献

Objectives
Our objective was to assess immune responses and their influencing factors in people living with HIV after messenger RNA (mRNA)-based COVID-19 booster vaccination (third dose).Methods
This was a retrospective cohort study of people living with HIV who received booster vaccination with BNT-162b2 or mRNA-1273 between October 2021 and January 2022. We assessed anti-spike receptor-binding domain (RBD) immunoglobulin G (IgG), virus neutralizing activity (VNA) titres reported as 100% inhibitory dilution (ID100), and T-cell response (using interferon-gamma-release-assay [IGRA]) at baseline and quarterly follow-up visits. Patients with reported COVID-19 during follow-up were excluded. Predictors of serological immune response were analyzed using multivariate regression models.Results
Of 84 people living with HIV who received an mRNA-based booster vaccination, 76 were eligible for analysis. Participants were on effective antiretroviral therapy (ART) and had a median of 670 CD4+cells/μL (interquartile range [IQR] 540–850). Following booster vaccination, median anti-spike RBD IgG increased by 705.2 binding antibody units per millilitre (BAU/mL) and median VNA titres increased by 1000 ID100 at the follow-up assessment (median 13 weeks later). Multivariate regression revealed that time since second vaccination was a predictor of stronger serological responses (p < 0.0001). No association was found for other factors, including CD4+ status, choice of mRNA vaccine, or concomitant influenza vaccination. In total, 45 patients (59%) had a reactive baseline IGRA, of whom two lost reactivity during follow-up. Of 31 patients (41%) with non-reactive baseline IGRA, 17 (55%) converted to reactive and seven (23%) remained unchanged following booster vaccination.Conclusions
People living with HIV with ≥500 CD4+cells/μL showed favourable immune responses to mRNA-based COVID-19 booster vaccination. A longer time (up to 29 weeks) since second vaccination was associated with higher serological responses, whereas choice of mRNA vaccine or concomitant influenza vaccination had no impact. 相似文献4.

Objective
To assess coronavirus disease 2019 (COVID-19) vaccine acceptance among people living with HIV (PLHIV) worldwide.Methods
We searched MEDLINE, PSYINFO, CINHAL, Scopus and EMBASE databases and other sources including free Google search and subject-specific journals from January 2020 to September 2021. The study population included adults (aged 18+ years) living with HIV and evaluated for COVID-19 vaccine acceptance. A random effect meta-analysis model was used to estimate the pooled COVID-19 vaccine acceptance rate. Subgroup analyses were performed, and factors associated with COVID-19 vaccine hesitancy underwent narrative analysis. Of 558 initial records, 14 studies were eligible for review.Results
The overall pooled COVID-19 vaccine acceptance rate among adult PLHIV was 62% (95% confidence interval [CI], 56%–69%). In subgroup analysis, the estimated pooled COVID-19 vaccine acceptance rate was higher in high-income countries: 63% (95% CI, 55%–70%) versus 62% (95% CI, 54%–71%) in low- and middle-income countries, and in studies conducted in 2022 (66% [95% CI, 58%–75%]) than in studies conducted in 2021 (57% [95% CI, 47%–68%]). Reasons for lower COVID-19 vaccine acceptance included higher monthly income, being non-homosexual, history of chronic disease, COVID-19-related medical mistrust, not knowing anyone who died of COVID-19, believing oneself to be immune to COVID-19, general vaccine refusal, negative attitude to the vaccine, concerns about efficacy, safety and side effects, distrust in common sources of vaccine-related information and using social media as a source of information on COVID-19.Conclusion
Among PLHIV, acceptance of COVID-19 vaccine is generally low. A greater emphasis on collaborative efforts between all concerned bodies is needed to boost vaccine acceptance in this population. 相似文献5.

The durability of vaccine-mediated immunity to SARS-CoV-2, the durations to breakthrough infection, and the optimal timings of booster vaccination are crucial knowledge for pandemic response. Here, we applied comparative evolutionary analyses to estimate the durability of immunity and the likelihood of breakthrough infections over time following vaccination by BNT162b2 (Pfizer-BioNTech), mRNA-1273 (Moderna), ChAdOx1 (Oxford-AstraZeneca), and Ad26.COV2.S (Johnson & Johnson/Janssen). We evaluated anti-Spike (S) immunoglobulin G (IgG) antibody levels elicited by each vaccine relative to natural infection. We estimated typical trajectories of waning and corresponding infection probabilities, providing the distribution of times to breakthrough infection for each vaccine under endemic conditions. Peak antibody levels elicited by messenger RNA (mRNA) vaccines mRNA-1273 and BNT1262b2 exceeded that of natural infection and are expected to typically yield more durable protection against breakthrough infections (median 29.6 mo; 5 to 95% quantiles 10.9 mo to 7.9 y) than natural infection (median 21.5 mo; 5 to 95% quantiles 3.5 mo to 7.1 y). Relative to mRNA-1273 and BNT1262b2, viral vector vaccines ChAdOx1 and Ad26.COV2.S exhibit similar peak anti-S IgG antibody responses to that from natural infection and are projected to yield lower, shorter-term protection against breakthrough infection (median 22.4 mo and 5 to 95% quantiles 4.3 mo to 7.2 y; and median 20.5 mo and 5 to 95% quantiles 2.6 mo to 7.0 y; respectively). These results leverage the tools from evolutionary biology to provide a quantitative basis for otherwise unknown parameters that are fundamental to public health policy decision-making.The unprecedented development of efficacious vaccines against SARS-CoV-2 has represented a triumph in the global effort to control the ongoing COVID-19 pandemic. Vaccines have been shown to provide short-term protection from major adverse health outcomes of hospitalization and death (1–4). However, protection against breakthrough infection wanes (5), and breakthroughs have been extensively documented (6, 7). In response, the Food and Drug Administration advisory committee has recommended a booster of the Pfizer-BioNTech and Moderna vaccines at least 5 mo after completion of the primary series to people ≥12 and ≥18 y of age, respectively (8). A booster dose of the Johnson & Johnson/Janssen vaccine has been authorized on a faster timescale—as early as 2 mo after the single dose to individuals 18 y of age and older (8). Nevertheless, the optimal timing of boosting remains challenging to assess. Consequently, rigorous prediction of the durability of immunity conferred by vaccination against the SARS-CoV-2 virus is essential to personal and public health decision-making, having major implications regarding policy decisions about COVID-19 vaccination around the world (9, 10).Short-term longitudinal studies of SARS-CoV-2-neutralizing antibodies in vaccinated individuals (11–13) can provide information crucial to our understanding of the durability of vaccine-mediated immunity. Peak antibody responses following vaccination versus natural responses have also been quantified (14), facilitating analytical comparison of initial immune responses. For endemic viruses, longitudinal data on reinfection can provide reinfection probabilities associated with antibody level. However, longitudinal data on SARS-CoV-2 reinfection are not available during the short term associated with pandemic spread. Nevertheless, longitudinal reinfection data for a diversity of coronaviruses have been collected (15–20). SARS-CoV-2 reinfection probabilities have been obtained from them by phylogenetic analysis, using continuous ancestral and descendent state estimation (21). These estimates, produced before reinfection was commonplace, proved accurate (predicting an 18% probability of reinfection at ∼270 d [ref. 21] that was validated by a subsequent empirical finding of 18% reinfection by 275 to 300 d after primary infection [ref. 22] and, likewise, predicting a 34% probability of reinfection at ∼450 d after primary infection [ref. 21] that was validated by a subsequent empirical finding of 34% breakthrough infection 420 to 480 d after primary vaccination [ref. 23]). Similar analyses pairing antibody response and rates of waning for each vaccine with infection probabilities can enable quantification of the durability of vaccine-mediated immunity against breakthrough infections. The aim of this study is to leverage data on antibody response to each vaccine and corresponding probabilities of infection to estimate the durability of vaccine-mediated immunity against breakthrough SARS-CoV-2 infection for four well-studied vaccines: mRNA-1273, BNT162b2, ChAdOx1, and Ad26.COV2.S. 相似文献

Background
Absolute changes in high-sensitivity cardiac troponin T (hs-cTnT) seem to have higher diagnostic accuracy in the early diagnosis of acute myocardial infarction compared with relative changes. It is unknown whether the same applies to high-sensitivity cardiac troponin I (hs-cTnI) assays and whether the combination of absolute and relative change might further increase accuracy.Methods
In a prospective, international multicenter study, high-sensitivity cardiac troponin (hs-cTn) was measured with 3 novel assays (hs-cTnT, Roche Diagnostics Corp, Indianapolis, Ind; hs-cTnI, Beckman Coulter Inc, Brea, Calif; hs-cTnI, Siemens, Munich, Germany) in a blinded fashion at presentation and after 1 and 2 hours in a blinded fashion in 830 unselected patients with suspected acute myocardial infarction. The final diagnosis was adjudicated by 2 independent cardiologists.Results
The area under the receiver operating characteristic curve for diagnosing acute myocardial infarction was significantly higher for 1- and 2-hour absolute versus relative hs-cTn changes for all 3 assays (P < .001). The area under the receiver operating characteristic curve of the combination of 2-hour absolute and relative change (hs-cTnT 0.98 [95% confidence interval {CI}, 0.97-0.99]; hs-cTnI, Beckman Coulter Inc, 0.97 [95% CI, 0.96-0.99]; hs-cTnI, Siemens, 0.96 [95% CI, 0.93-0.99]) were high and provided some benefit compared with the use of absolute change alone for hs-cTnT, but not for the hs-cTnI assays. Reclassification analysis confirmed the superiority of absolute changes versus relative changes.Conclusions
Absolute changes seem to be the preferred metrics for both hs-cTnT and hs-cTnI in the early diagnosis of acute myocardial infarction. The combination of absolute and relative changes provides a small added value for hs-cTnT, but not for hs-cTnI. 相似文献7.

Background
Healthcare workers (HCWs) have suffered considerable morbidity and mortality during the COVID-19 pandemic. Few studies have evaluated the CoronaVac vaccine effectiveness (VE), particularly in Eastern Europe, where the vaccine has been widely used.Methods
We conducted a prospective cohort study among HCWs in seven hospitals in Baku, Azerbaijan between May 17 and November 30, 2021, to evaluate primary series (two-dose) CoronaVac VE against symptomatic SARS-CoV-2 infection. Participants completed weekly symptom questionnaires, provided nasopharyngeal swabs for SARS-CoV-2 RT-PCR testing when symptomatic, and provided serology samples at enrollment that were tested for anti-spike and anti-nucleocapsid antibodies. We estimated VE as (1 – hazard ratio)*100 using a Cox proportional hazards model with vaccination status as a time-varying exposure, adjusting for hospital and previous SARS-CoV-2 infection status.Results
We enrolled 1582 HCWs. At enrollment, 1040 (66%) had received two doses of CoronaVac; 421 (27%) were unvaccinated. During the study period, 72 PCR-positive SARS-CoV-2 infections occurred; 36/39 (92%) sequenced samples were classified as Delta variants. Primary series VE against COVID-19 illness was 29% (95% CI: −51%; 67%) for the entire analysis period. For the Delta-only period (July 1–November 30, 2021), primary series VE was 19% (95% CI: −81%; 64%). For the entire analysis period, primary series VE was 39% (95% CI: −40%; 73%) for HCWs vaccinated within 14–149 days and 19% (95% CI: −81%; 63%) for those vaccinated ≥150 days.Conclusions
During a period in Azerbaijan characterized by mostly Delta circulation, VE point estimates suggested that primary series CoronaVac protected nearly 1 in 3 HCWs against COVID-19, but 95% confidence intervals were wide, with lower bounds that crossed zero, reflecting the limited precision of our VE estimates. Our findings underscore the need to consider booster doses for individuals who have received the primary series of CoronaVac. 相似文献8.
BackgroundAs COVID-19 vaccine effectiveness against SARS-CoV-2 infection was lower for cases of the Omicron vs the Delta variant, understanding the effect of vaccination in reducing risk of hospitalisation and severe disease among COVID-19 cases is crucial.AimTo evaluate risk reduction of hospitalisation and severe disease in vaccinated COVID-19 cases during the Omicron BA.1-predominant period in Navarre, Spain.MethodsA case-to-case comparison included COVID-19 epidemiological surveillance data in adults ≥ 18 years from 3 January–20 March 2022. COVID-19 vaccination status was compared between hospitalised and non-hospitalised cases, and between severe (intensive care unit admission or death) and non-severe cases using logistic regression models.ResultsAmong 58,952 COVID-19 cases, 565 (1.0%) were hospitalised and 156 (0.3%) were severe. The risk of hospitalisation was reduced within the first 6 months after full COVID-19 vaccination (complete primary series) (adjusted odds ratio (aOR): 0.06; 95% CI: 0.04–0.09) and after 6 months (aOR: 0.16; 95% CI: 0.12–0.21; pcomparison < 0.001), as well as after a booster dose (aOR: 0.06: 95% CI: 0.04–0.07). Similarly, the risk of severe disease was reduced (aOR: 0.13, 0.18, and 0.06, respectively). Compared with cases fully vaccinated 6 months or more before a positive test, those who had received a booster dose had lower risk of hospitalisation (aOR: 0.38; 95% CI: 0.28–0.52) and severe disease (aOR: 0.38; 95% CI: 0.21–0.68).ConclusionsFull COVID-19 vaccination greatly reduced the risk of hospitalisation and severe outcomes in COVID-19 cases with the Omicron variant, and a booster dose improved this effect in people aged over 65 years. 相似文献

Purpose
The primary aim was to evaluate the impact of COVID-19 on frailty in patients surviving a hip fracture. Secondary aims were to assess impact of COVID-19 on (i) length of stay (LoS) and post-discharge care needs, (ii) readmissions, and (iii) likelihood of returning to own home.Methods
This propensity score-matched case-control study was conducted in a single centre between 01/03/20–30/11/21. A ‘COVID-positive’ group of 68 patients was matched to 141 ‘COVID-negative’ patients. ‘Index’ and ‘current’ Clinical Frailty Scale (CFS) scores were assigned for frailty at admission and at follow-up. Data were extracted from validated records and included: demographics, injury factors, COVID-19 status, delirium status, discharge destination, and readmissions. For subgroup analysis controlling for vaccination availability, the periods 1 March 2020–30 November 2020 and 1 February 2021–30 November 2021 were considered pre-/post-vaccine periods.Results
Median age was 83.0 years, 155/209 (74.2%) were female and median follow-up was 479 days (interquartile range [IQR] 311). There was an equivalent median increase in CFS in both groups (+1.00 [IQR 1.00–2.00, p = 0.472]). However, adjusted analysis demonstrated COVID-19 was independently associated with a greater magnitude change (Beta coefficient [β] 0.27, 95% confidence interval [95% CI] 0.00–0.54, p = 0.05). COVID-19 in the post-vaccine availability period was associated with a smaller increase versus pre-vaccine (β −0.64, 95% CI −1.20 to −0.09, p = 0.023). COVID-19 was independently associated with increased acute LoS (β 4.40, 95% CI 0.22–8.58, p = 0.039), total LoS (β 32.87, 95% CI 21.42–44.33, p < 0.001), readmissions (β 0.71, 95% CI 0.04–1.38, p = 0.039), and a four-fold increased likelihood of pre-fracture home-dwelling patients failing to return home (odds ratio 4.52, 95% CI 2.08–10.34, p < 0.001).Conclusions
Hip fracture patients that survived a COVID-19 infection had increased frailty, longer LoS, more readmissions, and higher care needs. The health and social care burden is likely to be higher than prior to the COVID-19 pandemic. These findings should inform prognostication, discharge-planning, and service design to meet the needs of these patients. 相似文献10.

Background
We estimated combined protection conferred by prior SARS-CoV-2 infection and COVID-19 vaccination against COVID-19-associated acute respiratory illness (ARI).Methods
During SARS-CoV-2 Delta (B.1.617.2) and Omicron (B.1.1.529) variant circulation between October 2021 and April 2022, prospectively enrolled adult patients with outpatient ARI had respiratory and filter paper blood specimens collected for SARS-CoV-2 molecular testing and serology. Dried blood spots were tested for immunoglobulin-G antibodies against SARS-CoV-2 nucleocapsid (NP) and spike protein receptor binding domain antigen using a validated multiplex bead assay. Evidence of prior SARS-CoV-2 infection also included documented or self-reported laboratory-confirmed COVID-19. We used documented COVID-19 vaccination status to estimate vaccine effectiveness (VE) by multivariable logistic regression by prior infection status.Results
Four hundred fifty-five (29%) of 1577 participants tested positive for SARS-CoV-2 infection at enrollment; 209 (46%) case-patients and 637 (57%) test-negative patients were NP seropositive, had documented previous laboratory-confirmed COVID-19, or self-reported prior infection. Among previously uninfected patients, three-dose VE was 97% (95% confidence interval [CI], 60%–99%) against Delta, but not statistically significant against Omicron. Among previously infected patients, three-dose VE was 57% (CI, 20%–76%) against Omicron; VE against Delta could not be estimated.Conclusions
Three mRNA COVID-19 vaccine doses provided additional protection against SARS-CoV-2 Omicron variant-associated illness among previously infected participants. 相似文献11.

Background
The severity of Severe Acute Respiratory Syndrome Coronavirus 2 infection varies with age and time. Here, we quantify how age-specific risks of hospitalization, intensive care unit (ICU) admission, and death upon infection changed from February 2020 to June 2021 in the Netherlands.Methods
A series of large representative serology surveys allowed us to estimate age-specific numbers of infections in three epidemic periods (late-February 2020 to mid-June 2020, mid-June 2020 to mid-February 2021, and mid-February 2021 to late-June 2021). We accounted for reinfections and breakthrough infections. Severity measures were obtained by combining infection numbers with age-specific numbers of hospitalization, ICU admission, and excess all-cause deaths.Results
There was an accelerating, almost exponential, increase in severity with age in each period. The rate of increase with age was the highest for death and the lowest for hospitalization. In late-February 2020 to mid-June 2020, the overall risk of hospitalization upon infection was 1.5% (95% confidence interval [CI] 1.3–1.8%), the risk of ICU admission was 0.36% (95% CI: 0.31–0.42%), and the risk of death was 1.2% (95% CI: 1.0–1.4%). The risk of hospitalization was significantly increased in mid-June 2020 to mid-February 2021, while the risk of ICU admission remained stable over time. The risk of death decreased over time, with a significant drop among ≥70-years-olds in mid-February 2021 to late-June 2021; COVID-19 vaccination started early January 2021.Conclusion
Whereas the increase in severity of Severe Acute Respiratory Syndrome Coronavirus 2 with age remained stable, the risk of death upon infection decreased over time. A significant drop in risk of death among elderly coincided with the introduction of COVID-19 vaccination. 相似文献12.

Objective
Patients with systemic lupus erythematosus (SLE) seem to experience an increased prevalence of oncogenic virus infections. The aim of the present study was to investigate whether SLE patients have an increased risk of virus‐associated malignancies, defined as malignancies potentially caused by virus infection.Methods
A hospital‐based cohort of 576 SLE patients was linked to the Danish Cancer Registry. The cohort was followed up for malignancies from the date of SLE diagnosis, and standardized incidence ratios (SIRs) were calculated for various forms of cancer.Results
The median duration of followup was 13.2 years. Compared to the general population, the patients experienced an increased overall risk of cancer (SIR 1.6 [95% confidence interval (95% CI)] 1.2–2.0). We observed an increased risk of virus‐associated cancers combined (SIR 2.9 [95% CI 2.0–4.1]). Among human papillomavirus (HPV)–associated malignant and premalignant conditions, high risk was found for anal cancer (SIR 26.9 [95% CI 8.7–83.4]), vaginal/vulvar cancer (SIR 9.1 [95% CI 2.3–36.5]), epithelial dysplasia/carcinoma in situ of the uterine cervix (SIR 1.8 [95% CI 1.2–2.7]), and nonmelanoma skin cancer (SIR 2.0 [95% CI 1.2–3.6]). Increased SIRs were also found for other potentially virus‐induced cancer types (liver cancer SIR 9.9 [95% CI 2.5–39.8], bladder cancer SIR 3.6 [95% CI 1.4–9.7], and non‐Hodgkin's lymphoma SIR 5.0 [95% CI 1.9–13.3]).Conclusion
The patients in this SLE cohort experienced an increased risk of HPV‐associated tumors and other potentially virus‐induced cancers during long‐term followup. Our findings call for clinical alertness to oncogenic virus infections in SLE patients.13.

Objective
To assess the prevalence of and risk factors for Raynaud's phenomenon (RP) in a French working population characterized by various levels of exposure to work‐related constraints.Methods
The study population comprised 3,710 workers (2,161 men and 1,549 women) who were followed up by 83 occupational physicians and were representative of the region's workforce. RP, as diagnosed by a questionnaire and a standardized interview, was defined as the occurrence of at least occasional attacks of finger blanching triggered by exposure to environmental cold during the previous 12 months. Personal factors and work exposure were assessed by self‐administered questionnaires. The associations between RP and personal and occupational factors were analyzed using logistic regression modeling.Results
A total of 87 cases of RP (56 women and 31 men) were diagnosed. The population‐based annual prevalence rates of RP were 3.6% (95% confidence interval [95% CI] 2.7–4.5%) for women and 1.4% (95% CI 0.9–1.9%) for men. Women had a higher risk of RP (odds ratio [OR] 2.1 [95% CI 1.3–3.4]) and the risk decreased continuously with body mass index (OR for 1‐kg/m2 increment 0.87 [95% CI 0.81–0.94]). The risk of RP increased consistently but moderately with age after 35 years (ORs ranging from 2.0 [95% CI 1.1–3.8] to 2.9 [95% CI 1.6–5.2]). Among the work‐related factors studied, RP was associated with an exposure to a cold environment or objects (OR 2.2 [95% CI 1.0–4.6]), a high repetitiveness of a task (OR 1.7 [95% CI 1.0–2.7]), a high psychological demand at work (OR 1.7 [95% CI 1.0–2.7]), and low support from supervisors (OR 2.4 [95% CI 1.5–3.8]).Conclusion
Personal and work‐related factors were associated with RP, with a clear difference between the sexes. Work‐related psychosocial stressors played a significant role independently of biomechanical and environmental exposure. 相似文献14.

Patients with a radiological diagnosis of ARVD were recruited into this single-center prospective cohort study between 1986 and 2014. Data collected included baseline co-morbid conditions, annualized prescribed medications and laboratory data (serum creatinine [υmol/L], proteinuria [g/24 h]). Multivariable Cox regression analysis was used to explore association with these end-points: death, end-stage kidney disease (ESKD), cardiovascular event (CVE) and the first of any of these events.Results
A total of 872 patients were recruited into this study. However, 42 patients were excluded due to missing baseline data and hence case records for 830 patients were reviewed. Over median follow-up of 57.1 months (interquartile range: 21.7–96.9), incidence per 100 patient years of death, ESKD, CVE and any event was 13.5, 4.2, 8.9 and 21.0 respectively. Macrovascular disease (MVD), congestive heart failure (CHF), flash pulmonary oedema (FPE) and greater proteinuria at baseline were individually associated with increased risk for all end-points in multivariable analysis (Death: MVD –HR 1.24 [95% CI 1.02–1.50]; CHF –HR 1.33 [95% CI 1.08–1.64]; FPE – HR 2.10 [95% CI 1.50–2.92]; proteinuria – HR 1.14 [95% CI 1.08–1.20]). Higher estimated glomerular filtration rate at time of diagnosis was significantly associated with reduced risk of all end-points (Death: HR 0.92 [95% CI 0.89–0.94])., Administration of statins and renin angiotensin blockade (RAB) at baseline were also associated with reduced adverse events, especially death (RAB: HR 0.83 [95% CI 0.70–0.98]; statins: HR 0.79 [95% CI 0.66–.94]) and ESKD (RAB: HR 0.84 [95% CI 0.71–1.00]; statins: HR 0.79 [95% CI 0.66–0.93]). Revascularization was associated with reduced risk of death (HR 0.65 [95% CI 0.51–0.83]) and ESKD (HR 0.59 [95% CI 0.46–0.76]).Conclusion
All patients with ARVD require intensive vascular protection therapy to help mitigate systemic atherosclerosis, optimize cardiovascular risk and improve clinical outcomes. More effort is required to identify the minority of patients who may benefit from revascularization.15.

Objective
The effect of non–shared epitope HLA–DRB1 alleles on rheumatoid arthritis (RA) is poorly understood. This study was undertaken to investigate the effects of several HLA–DRB1 alleles, independent of the shared epitope, on the risk of developing anti–citrullinated protein antibody (ACPA)–positive or ACPA‐negative RA in a large case–control study.Methods
HLA typing for the DRB1 gene was performed in 1,352 patients with RA and 922 controls from the Swedish Epidemiological Investigation of Rheumatoid Arthritis study. Relative risks (RRs) and 95% confidence intervals (95% CIs) were calculated.Results
DRB1*13 was found to protect against ACPA‐positive RA when stratifying for the shared epitope and using a dominant genetic model (RR 0.41 [95% CI 0.26–0.64]). Furthermore, DRB1*13 neutralized the effect of the shared epitope in ACPA‐positive RA (RR 3.91 [95% CI 3.04–5.02] in patients who had the shared epitope but not DRB1*13, and RR 1.22 [95% CI 0.81–1.83] in patients with both the shared epitope and DRB1*13, as compared with patients negative for both the shared epitope and DRB1*13). However, we did not replicate the previous published risk of ACPA‐negative RA conferred by DRB1*03 when a dominant genetic model was used (RR 1.29 [95% CI 0.91–1.82]). Similarly, no significant effect of DRB1*03 on RR for ACPA‐negative RA was seen using the recessive genetic model (RR 1.18 [95% CI 0.6–2.4]). In contrast, the combination of DRB1*03 and DRB1*13 was significantly associated with increased risk of developing ACPA‐negative RA (RR 2.07 [95% CI 1.17–3.67]).Conclusion
Our findings indicate that the DRB1*13 allele plays a dual role in the development of RA, by protecting against ACPA‐positive RA but, in combination with DRB1*03, increasing the risk of ACPA‐negative RA.16.

Polymyalgia rheumatica (PMR) is an inflammatory rheumatic disease characterized by stiffness and aching mainly in the shoulders, neck and hip girdles. The underlying pathogenesis of PMR involves myeloid lineage activation with a high expression of pattern recognition receptors. In addition, vaccination against severe acute respiratory syndrome coronavirus 2 with mRNA-1273 functions as both an immunogen and intrinsic adjuvant. It leads to the activation of innate immunity, resulting in antibody production. We herein report the first case of PMR-like syndrome seven days after mRNA-1273 vaccination. Reassuringly, the symptoms, such as pain of the neck, shoulder girdle and pelvic girdle, as well as elevated inflammatory markers were resolved within a month without glucocorticoid or immunosuppressant administration. 相似文献

Background
Cardiac troponins (cTn) are to date the most sensitive and specific biochemical markers of myocardial injury. Abnormal breathing patterns in patients with obstructive sleep apnea (OSA) may cause myocardial cell stress detectable by novel cTn assays. The objectives of this study were to investigate whether a new single-molecule cTnI (S-cTnI) assay and a commercially available high-sensitivity cTnT (hs-cTnT) assay would detect myocyte injury in individuals evaluated for possible OSA, and to explore their relation to variables of disordered breathing during sleep.Methods
Consecutive individuals referred to Lovisenberg Diakonale Hospital’s sleep laboratory between 1 October 2009 and 1 March 2010 were included. We measured cTn in specimens collected the morning after sleep and studied these in relation to variables recorded during polygraphy or polysomnography.Results
All 222 (100 %) individuals had measurable cTn levels using either assay. Stratified into categories according to the apnea–hypopnea index (AHI), patients with OSA (AHI ≥5) had a different distribution of S-cTnI (P?=?0.036) and hs-cTnT (P?=?0.002) compared to those without (AHI <5). The median (quartiles 1–3) were 3.0 (1.9–6.0) versus 2.3 (1.6–3.8) ng/l for S-cTnI, and 7.0 (5.5–8.7) versus 6.2 (4.9–7.2) ng/l for hs-cTnT. However, in multiple median regression analyses adjusted for conventional predictors, neither S-cTnI (P?=?0.57) nor hs-cTnT (P?=?0.80) were significantly associated with AHI.Conclusions
This study reveals no association independent of conventional predictors between OSA and myocardial cell injury measured by S-cTnI and hs-cTnT assays. Our findings support a search for novel biomarkers for prognostication of OSA. 相似文献18.

The objective of this study was to investigate the incidence and risk factors associated with COVID-19 vaccine breakthrough infections. We included all persons ≥18 years that had been fully vaccinated against COVID-19 for ≥14 days, between 1 February 2021 and 5 December 2021, in Belgium. The incidence of breakthrough infections (laboratory confirmed SARS-CoV-2-infections) was determined. Factors associated with breakthrough infections were analyzed using COX proportional hazard models. Among 8,062,600 fully vaccinated adults, we identified 373,070 breakthrough infections with an incidence of 11.2 (95%CI 11.2–11.3)/100 person years. Vaccination with Ad26.COV2.S (HR1.54, 95%CI 1.52–1.56) or ChAdOx1 (HR1.68, 95%CI 1.66–1.69) was associated with a higher risk of a breakthrough infection compared to BNT162b2, while mRNA-1273 was associated with a lower risk (HR0.68, 95%CI 0.67–0.69). A prior COVID-19-infection was protective against a breakthrough infection (HR0.23, 95%CI 0.23–0.24), as was an mRNA booster (HR0.44, 95%CI 0.43–0.45). During a breakthrough infection, those who had a prior COVID-19 infection were less likely to have COVID-19 symptoms of almost all types than naïve persons. We identified risk factors associated with breakthrough infections, such as vaccination with adenoviral-vector vaccines, which could help inform future decisions on booster vaccination strategies. A prior COVID-19 infection lowered the risk of breakthrough infections and of having symptoms, highlighting the protective effect of hybrid immunity. 相似文献

Objective
Experimental studies indicate that patients with Wegener's granulomatosis (WG) experience accelerated atherosclerosis. The purpose of this study was to investigate whether the occurrence of overt ischemic heart disease (IHD) is increased in WG.Methods
A total of 293 WG patients were included in the study. Information on all hospitalizations for IHD in Denmark from 1977 to 2006 was obtained from the Danish National Hospital Register. The WG patients were compared with the Danish background population with respect to rates of hospitalization for clinical manifestations of IHD after the date of vasculitis diagnosis by calculating standardized ratios of observed to expected (O:E) events.Results
Sixty‐three first IHD events were registered in the WG group during the 2,482 patient‐years of followup, corresponding to a significantly increased O:E ratio for IHD of 1.9 (95% confidence interval [95% CI] 1.4–2.4). A significantly increased risk was found for acute myocardial infarction (MI) (O:E ratio 2.5 [95% CI 1.6–3.7]), but not for angina pectoris (O:E ratio 1.3 [95% CI 0.7–2.1]). In analyses stratified according to the time between the diagnosis of vasculitis and the cardiovascular event, increased O:E ratios were found for IHD and acute MI occurring <5.0 years after WG diagnosis (2.1 [95% CI 1.4–3.0] for IHD and 3.6 [95% CI 2.0–5.9] for acute MI) and for IHD occurring ≥10.0 years after WG diagnosis (2.2 [95% CI 1.3–3.4]). Significantly increased O:E ratios for IHD and acute MI were found in patients who were ≥50.0 years of age at the time of diagnosis of WG, in male patients, and in patients who received high cumulative doses of cyclophosphamide.Conclusion
Compared with the background population, WG patients seem to experience an increased number of both early and late cardiovascular events due to IHD.20.
