A COVID-19 monitoring process for healthcare workers utilizing occupational health.

BACKGROUND: Hospital-based occupational health (HBOH) is uniquely positioned to not only prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission, but to care for healthcare workers (HCWs) sick with coronavirus disease 2019 (COVID-19). AIMS: The primary objective of this study is to describe a system where HBOH services were adapted to provide a monitoring programme whereby HCWs with SARS-CoV-2 received daily evaluations and treatment options in order to improve access to care, and to report the clinical outcomes and predictors of hospitalization in HCWs enrolled in the programme. A secondary objective is to compare clinical outcomes to data on national HCWs with COVID-19. METHODS: This retrospective cohort study used survey data collected on HCWs at a university health system with COVID-19 from 1 March 2020 through 1 December 2021. A firth regression model was used to examine the unadjusted and adjusted association between clinical factors and hospitalization. RESULTS: The study cohort included 4814 HCWs with COVID-19. Overall hospitalizations were 119 (2%), and there were six deaths (0.12%). Predictors of hospitalization include several co-morbidities and symptoms. A total of 1835 HCWs monitored before vaccine or monoclonal antibody availability were compared with data on U.S. HCWs in a similar time period. The monitored HCWs had a lower rate of co-morbidities (19% versus 44%, P < 0.001), a lower hospitalization rate (3% versus 8% P < 0.001) and case-fatality rate (0.11% versus 0.95% P < 0.001). CONCLUSIONS: This monitoring strategy for COVID-19 may be feasible for HBOH systems to implement and improve access to care, but more data are needed to determine if it improves outcomes.

What are the risk factors for complications after combined injury of the pelvic ring and acetabulum?

PURPOSE: Combined acetabular and pelvic ring injuries represent a unique subset of pelvic trauma and little is known regarding their complications and outcomes. We sought to further evaluate these injury patterns and quantify their outcomes. METHODS: A retrospective review at a single level 1 trauma center was performed on all patients with operatively treated combined ring and acetabulum injuries during a seven-year period. Main outcome measurements include all-cause complication including residual neurologic deficit, deep infection, conversion to total hip arthroplasty, deep venous thrombosis and mortality. RESULTS: Seventy operatively treated combined ring and acetabulum patients with one-year follow-up were reviewed. The overall complication rate was 44%. Hip dislocation occurred in 40% of the cohort and was significantly associated with residual neurologic deficit and all-cause complication. Angiography with embolization was not associated with an increased rate of deep infection. Open acetabular approaches had a significantly higher complication rate compared to percutaneous procedures. Delay to definitive fixation greater than 36 h trended toward but did not reach association with all complications. CONCLUSION: Combined injuries to the acetabulum and pelvic ring have high rates of complications. No individual fracture patterns were identified as risk factors, but hip dislocation was associated with an increased rate of complications. When possible, percutaneous reduction and fixation of acetabular fractures and early definitive fracture fixation lead to lower rates of complications. Use of angiography with embolization appears to be safe and does not increase the risk of infection or other complications.

SGO and the elephant that is still in the room: Wellness, burnout and gynecologic oncology.

OBJECTIVE: To measure wellness and burnout among gynecologic oncology clinicians and identify trends and at-risk populations to inform future interventions. METHODS: Gynecologic oncologist (GO) and advanced practice provider (APP) responses to the 2020 Society of Gynecologic Oncology State of the Society survey were analyzed. The Maslach Burnout Inventory criteria for burnout was used. Work-life balance was scored on a 5-point Likert scale. Chi-square tests were used to compare mental health factors and the prevalence of burnout. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for associations between burnout and gender. RESULTS: 543 survey responses were included for analysis. Most GO (54%) and all APP respondents were female. Female GOs were disproportionately affected by burnout particularly in the Northeast (female(F): 40.9% vs male(M): 19.1%, p = 0.007) and South (F: 42.5% vs M:22.9%, p = 0.01). Burnout in female GOs over 40 was 1.79 (CI: 1.13-2.83; p-value 0.01) times higher than similarly aged males. Females in non-private practice experienced burnout 1.66 times that of males in similar positions (CI: 1.18-2.94; p < 0.0001). Female GOs reported the worst work-life balance across all 5 domains. APPs and female GOs experienced more stress and feeling overwhelmed compared to men. GOs were more reluctant to see a mental health professional (p = 0.0003) or take medication (p = 0.009) than APPs. CONCLUSIONS: Burnout in gynecologic oncology persists in both genders and is felt most acutely by female GOs. APPs are not immune and would benefit from inclusion in future research to mitigate burnout in healthcare clinicians.

Combined total hip and knee arthroplasty during the same hospital admission: is it safe?.

AIMS: The purpose of this study was to compare outcomes of combined total joint arthroplasty (TJA) (total hip arthroplasty (THA) and total knee arthroplasty (TKA) performed during the same admission) versus bilateral THA, bilateral TKA, single THA, and single TKA. Combined TJAs performed on the same day were compared with those staged within the same admission episode. PATIENTS AND METHODS: Data from the National (Nationwide) Inpatient Sample recorded between 2005 and 2014 were used for this retrospective cohort study. Postoperative in-hospital complications, total costs, and discharge destination were reviewed. Logistic and linear regression were used to perform the statistical analyses. p-values less than 0.05 were considered statistically significant. RESULTS: Combined TJA was associated with increased risk of deep vein thrombosis, prosthetic joint infection, irrigation and debridement procedures, revision arthroplasty, length of stay (LOS), and in-hospital costs compared with bilateral THA, bilateral TKA, single THA, and single TKA. Combined TJA performed on separate days of the same admission showed no statistically significant differences when compared with same-day combined TJA, but trended towards decreased total costs and total complications despite increased LOS. CONCLUSION: Combined TJA is associated with increased in-hospital complications, LOS, and costs. We do not recommend performing combined TJA during the same hospital stay.

Remission and low disease activity state (LDAS) are protective of intermediate and long-term outcomes in SLE patients. Results from LUMINA (LXXVIII), a multiethnic, multicenter US cohort.

OBJECTIVE: The objective of this report is to determine the impact of remission and low disease activity state (LDAS) on damage accrual and mortality in systemic lupus erythematosus (SLE) patients. PATIENTS AND METHODS: Visits from the Lupus in Minority populations: Nature vs. Nurture (LUMINA) cohort were categorized into remission (Systemic Lupus Activity Measure (SLAM) score = 0 and prednisone ≤ 5 mg/day and no immunosuppressants), LDAS ((not on remission), SLAM score ≤ 3, prednisone ≤ 7.5 mg/day, no immunosuppressants), or neither: active. Remission and LDAS visits were combined because of the relatively small number of remission visits. Their impact on damage accrual and mortality were examined by Poisson and logistic multivariable regressions adjusting for variables known to affect these outcomes. RESULTS: A total of 3879 visits for 558 patients (28% Caucasian, 37% African descent, 35% Hispanic) were studied. These visits corresponded to 71 in remission, 585 in LDAS, and 3223 active. The longer the percentage of time the patients were in remission/LDAS, the less damage accrual observed (rate ratio 0.1773 (95% confidence interval (CI) 0.1216 to 0.2584) p < 0.0001). A trend was observed in terms of mortality although statistical significance was not reached (odds ratio 0.303 (95% CI 0.063 to 1.456), p = 0.1360). CONCLUSIONS: The longer the patient's state on Remission/LDAS, the less damage accrual that occurs. The protective effect on mortality was not statistically significant.

Self-reported vs state-recorded motor vehicle collisions among older community dwelling individuals.

INTRODUCTION: Motor vehicle collisions (MVCs) continue to place an increased burden on both individuals and health care systems. Self-reported and state-recorded police reports are the most common methods for MVC evaluation in epidemiologic studies, with varying degrees of agreement of information when compared in previous studies. The objective of the current study is to address the differences in MVC reporting and provide a more robust measure of the agreement between self-reported and state-recorded MVCs in a community dwelling population of older adults. METHODS: A three-year prospective study was conducted in a population-based sample of 2000 licensed drivers aged 70 and older. At annual visits, participants were asked to self-report information on any MVC that occurred over the prior year where police were called to the scene. Information on police-reported MVCs was also ascertained from Alabama official state-recorded databases. The kappa coefficient was calculated to determine overall agreement between any self-reported and state-recorded crashes, as well as the raw number of crashes reported. In addition, agreement was stratified by demographics, health status, medication use, functional status (i.e. vision, cognition), and driving habits. RESULTS: 1747 participants who completed three years of follow up were involved in 225 state-recorded MVCs and 208 self-reported MVCs yielding overall substantial agreement between any self-report and state-recorded MVC (kappa=0.64). Cumulative number of self-reported and state-recorded MVCs was also compared, with agreement slightly reduced (kappa=0.55). The clinical characteristic resulting in the greatest variation in agreement with drivers was impaired contrast sensitivity showing better agreement between self-reported and state-recorded MVCs (kappa=0.9) than those with non-impaired contrast sensitivity (kappa=0.6). CONCLUSION: Study results showed substantial agreement between self-reported and state-recorded MVCs for any MVC involvement among the study population. When examining the reporting of the total number of MVCs over the three year period, agreement was reduced to a moderate level. There was consistency in agreement across MVC risk factors except among individuals with contrast sensitivity. These findings have implications for the design and analytic planning of epidemiologic and clinical research focused on MVCs.

Gender-associated comorbidities in rheumatoid arthritis and their impact on outcome: data from GENIRA.

GENIRA [Gender in Rheumatoid Arthritis (RA)] is a comprehensive project aimed at studying gender differences in RA patients and how these differences impact on these patient outcomes. We are now reporting such data. Seventy RA patients of each gender were cross-sectionally evaluated following a preestablished protocol. Univariate and multivariate analyses focused in the different gender-associated comorbidity profiles and how they impact in the quality of life and disability of RA patients as assessed by the SF-36 and the Modified Health Assessment Questionnaire (M-HAQ), respectively. Both groups were comparable regarding their main demographic and clinical features. Different comorbidity profiles were found in both genders, with higher frequencies of diabetes mellitus, peptic ulcer, ischemic heart disease, smoking and chronic obstructive pulmonary disease among men and of depression and osteoporosis among women. The M-HAQ was lower in women than in men (0.89 ± 2.6 vs 0.22 ± 0.9, p = 0.04) as there were some sub-scales of the SF-36 [mental health (63.7 ± 22.0 vs 71.8 ± 21.1; p = 0.02), general health (41.3 ± 21.7 vs 50.0 ± 24.3; p = 0.02), physical functioning (PF) (57.7 ± 22.1 vs 67.3 ± 22.7; p = 0.01) and the physical summary component (PSC) (39.3 ± 8.9 vs 42.4 ± 9.3, p = 0.04)]. Multivariate analysis indicated the independent association between depression and osteoporosis rather than gender with the M-HAQ, PSC and PF and of only depression with the MH and GH. Women with RA present significantly worse disability and QOL outcomes than men; these differences can be explained by female gender-associated comorbidities such as depression and osteoporosis rather than gender per se.

Factors associated with disease expression patterns in systemic lupus erythematosus patients: results from LUMINA (LXXVII), a multiethnic US cohort.

Objective The objective of this study was to determine the association of disease expression patterns with demographic and clinical characteristics in SLE. Methods Patients from a multi-ethnic SLE cohort were included. Disease expression patterns were defined as acute SLE and insidious SLE; this group was divided into those who accrued three ACR criteria and then accrued the fourth (insidious pattern A) and those who have one or two and then accrued four criteria (insidious pattern B). Disease activity was ascertained with the SLAM-R and disease damage with SLICC/ACR damage index. Variables were compared using analysis of variance for numeric variables and χ2 for categorical variables. Multivariable analyses adjusting for possible confounders were performed. Results Six hundred and forty patients were included; the most frequent pattern was the insidious pattern B, with 415 (64.8%) patients, followed by the acute SLE group with 115 (18.0%) and the insidious pattern A with 110 (17.2%) patients. Patients from the insidious pattern A were older at diagnosis (pattern A: 39.8 vs pattern B: 36.7 vs acute: 32.4 years; p < 0.0001), more educated (13.6 vs 13.1 vs 12.1; p = 0.0008) and with a less active disease at baseline (8.8 vs 9.2 vs 10.7; p = 0.0227). Caucasian and Hispanic (Puerto Rico) ethnicities were overrepresented in this group (40.0% vs 27.7% vs 19.1% and 18.2% vs 17.1% vs 9.6%; p = 0.0003). Conclusions More insidious onset is associated with older age, Caucasian ethnicity, higher level of education, and lower disease activity than those with acute onset. However, after multivariable analyses, disease activity was not associated with any disease expression pattern.

The role of genetic variants in CRP in radiographic severity in African Americans with early and established rheumatoid arthritis.

This study investigates the association of CRP (C-reactive protein) single-nucleotide polymorphisms (SNPs) with plasma CRP levels and radiographic severity in African Americans with early and established rheumatoid arthritis (RA). Using a cross-sectional case-only design, CRP SNPs were genotyped in two independent sets of African Americans with RA: Consortium for the Longitudinal Evaluation of African Americans with RA (CLEAR 1) and CLEAR 2. Radiographic data and CRP measurements were available for 294 individuals from CLEAR 1 (median (interquartile range (IQR) 25-75) disease duration of 1 (0.6-1.6) year) and in 407 persons from CLEAR 2 (median (IQR 25-75) disease duration of 8.9 (3.5-17.7) years). In CLEAR 1, in adjusted models, the minor allele of rs2808630 was associated with total radiographic score (incident rate ratio 0.37 (95% confidence interval (CI) 0.19-0.74), P-value=0.0051). In CLEAR 2, the minor allele of rs3093062 was associated with increased plasma CRP levels (P-value=0.002). For each rs3093062 minor allele, the plasma CRP increased by 1.51 (95% CI 1.15-1.95) mg dl(-1) when all the other covariates remained constant. These findings have important implications for assessment of the risk of joint damage in African Americans with RA.

Effects of statins on proinflammatory/prothrombotic biomarkers and on disease activity scores in SLE patients: data from LUMINA (LXXVI), a multi-ethnic US cohort.

OBJECTIVES: We sought to determine the effect of statin therapy on the levels of proinflammatory/prothrombotic markers and disease activity scores in patients with SLE in a multi-ethnic, multi-centre cohort (LUMINA). METHODS: Plasma/serum samples from SLE patients placed on statins (n=21) therapy taken before and after at least 6 months of treatment were tested. Disease activity was assessed using SLAM-R scores. Interleukin (IL)-1ß, IL-6, IL-8, tumour necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF) and soluble CD40 ligand (sCD40L) levels were determined by a multiplex immunoassay. Soluble intercellular cell adhesion molecule (ICAM)-1, vascular cell adhesion molecule (VCAM)-1 and anticardiolipin (aCL) antibodies were evaluated using ELISA assays while high sensitivity C-reactive protein (hsCRP) was assessed by nephelometry. Plasma/serum samples from frequency- matched healthy donors were used as controls. RESULTS: Levels of IL-6, VEGF, sCD40L and TNF-α were significantly elevated in SLE patients versus controls. Statin therapy resulted in a significant decrease in SLAM-R scores (p=0.0199) but no significant changes in biomarker levels were observed. There was no significant association of biomarkers with SLAM-R scores. CONCLUSIONS: Statin therapy resulted in significant clinical improvement in SLE patients, underscoring the use of statins in the treatment of SLE.

The American College of Rheumatology and the Systemic Lupus International Collaborating Clinics classification criteria for systemic lupus erythematosus in two multiethnic cohorts: a commentary.

The authors offer some comments on the advantages and possible drawbacks of using the SLICC criteria in longitudinal observational studies and clinical trials after applying and comparing them to the ACR criteria in two multinational, multiethnic lupus cohorts.

Ethnicity in systemic lupus erythematosus (SLE): its influence on susceptibility and outcomes.

Ethnicity is a biological and a social construct which encompasses ancestral genes, cultural, geographic and socioeconomic characteristics shared within a population. It is clear that no homogeneous racial groups exist within the human race as demonstrated when examining ancestry informative markers. Both the genetic and non-genetic components of ethnicity exert influence in the expression and outcome of systemic lupus erythematosus (SLE), including disease activity, damage accrual, work disability and mortality. Although it is difficult to determine the extent to which the differences observed in these parameters are caused by genetic or non-genetic factors, early in the disease genetic factors seem to play a more important role as determinants of the differences observed between SLE patients from various ethnic groups. Over the course of the disease, non-genetic factors seem to play a more important role. By and large, SLE is more frequent and more severe with higher disease activity and more damage accrual in non-Caucasian populations (Hispanics, African descendants and Asians) than in Caucasians. To overcome these differences it is necessary to optimize health care access to disadvantaged populations and use innovative tools to increase disease awareness and improve treatment adherence.

Effect of hydroxychloroquine treatment on pro-inflammatory cytokines and disease activity in SLE patients: data from LUMINA (LXXV), a multiethnic US cohort.

OBJECTIVE: We sought to determine the effect of hydroxychloroquine therapy on the levels proinflammatory/prothrombotic markers and disease activity scores in patients with systemic lupus erythematosus (SLE) in a multiethnic, multi-center cohort (LUMINA). METHODS: Plasma/serum samples from SLE patients (n = 35) were evaluated at baseline and after hydroxychloroquine treatment. Disease activity was assessed using SLAM-R scores. Interferon (IFN)-α2, interleukin (IL)-1ß, IL-6, IL-8, inducible protein (IP)-10, monocyte chemotactic protein-1, tumor necrosis factor (TNF)-α and soluble CD40 ligand (sCD40L) levels were determined by a multiplex immunoassay. Anticardiolipin antibodies were evaluated using ELISA assays. Thirty-two frequency-matched plasma/serum samples from healthy donors were used as controls. RESULTS: Levels of IL-6, IP-10, sCD40L, IFN-α and TNF-α were significantly elevated in SLE patients versus controls. There was a positive but moderate correlation between SLAM-R scores at baseline and levels of IFN-α (p = 0.0546). Hydroxychloroquine therapy resulted in a significant decrease in SLAM-R scores (p = 0.0157), and the decrease in SLAM-R after hydroxychloroquine therapy strongly correlated with decreases in IFN-α (p = 0.0087). CONCLUSIONS: Hydroxychloroquine therapy resulted in significant clinical improvement in SLE patients, which strongly correlated with reductions in IFN-α levels. This indicates an important role for the inhibition of endogenous TLR activation in the action of hydroxychloroquine in SLE and provides additional evidence for the importance of type I interferons in the pathogenesis of SLE. This study underscores the use of hydroxychloroquine in the treatment of SLE.

Is familial lupus different from sporadic lupus? Data from LUMINA (LXXIII), a multiethnic US cohort.

The aim of this study was to characterize the clinical features of familial lupus, and determine its influence on damage accrual and survival using data from LUMINA, a longitudinal multiethnic US cohort. Familial lupus was defined as patients with a first-degree relative with systemic lupus erythematosus. Relative risks were estimated by logistic regression; odds ratios (ORs) and their 95% confidence intervals (CIs) were the measure of association for familial lupus. Hazard ratios were calculated using Cox proportional hazards adjusted for potential confounders for damage and survival. Of 644 patients, 32 had familial and 612 had sporadic lupus; both groups were of comparable age (~36 years). Patients with familial lupus were, in decreasing order of frequency, siblings, parents and children. In multivariable analyses, mucosal ulcers (OR = 1.92, 95% CI 0.65-5.70), mitral valve prolapse (OR = 1.74, 95% CI 0.50-6.10), cerebrovascular disease (OR = 4.18, 95% CI 0.98-17.76) and oral contraceptive use (ever/never; OR = 2.51, 95% CI 0.88-7.19) were more likely in familial lupus, but a history of low platelet count (<150,000/mm(3); OR=0.31, 95% CI 0.08-1.17) and pulmonary disease activity (OR=0.39, 95% CI 0.14-1.20) were less likely. However, none of these associations reached statistical significance. Familial lupus was not significantly associated with a shorter time to either damage accrual or death (HR = 0.77, 95% CI 0.37-1.59, p = 0.4746 and HR = 0.20, 95% CI 0.03-1.47, p = 0.2020, respectively). We conclude that although some clinical differences were observed between patients with familial and sporadic lupus, familial lupus was not associated with a significantly greater disease burden (damage, survival) than sporadic lupus.

Bone properties surrounding hydroxyapatite-coated custom osseous integrated dental implants.

Calcium phosphate (hydroxyapatite or HA) coatings have been applied to Custom Osseous Integrated Implants (COIIs) to improve the quality of the bone-implant integration, yet little is known concerning the biomechanical properties of bone surrounding the HA-coated implants in humans over the long term. The purpose of this study was to characterize the mechanical and histomorphometric properties of the bone along the implant interface. Specimens were prepared from three similar mandibular implants that were functional in three female patients for about 11 years. Histomorphometric analyses showed bone-implant contact averaging 75% for all specimens. Area coverage of residual HA-coating ranged from 52 to 70%. When compared with previous studies, these results show a relatively high percentage of residual HA after a decade in vivo. Nanoindentation showed similar average values of hardness and modulus (p = 0.53 and p = 0.56, respectively) comparing bone adjacent to residual HA-coating and regions where the coating was absent. The elastic modulus was significantly lower for bone near the bone-implant interface (<200 µm) as compared with bone distant (>1000 µm) from the interface (p = 0.05), thereby reflecting different properties of the bone near these interfaces. Backscattered electron imaging showed darker gray levels which indicated decreased mineral content in bone adjacent to the implant, consistent with the nanoindentation results.

Factors associated with incomplete childhood immunization among residents in St. Mary, Jamaica.

AIM: To investigate factors associated with caregiver failure to complete immunizations for their children in the parish of St. Mary, Jamaica. METHODS: A case-control study was conducted with 50 cases defined as caregivers who failed to immunize their children and 179 controls defined as caregivers of children who were properly immunized. The cases were caregivers of children who were randomly selected from clinic records of children who failed to complete their immunization within the study period. Controls were caregivers of children who were identified to have completed their immunization from a similar list. Cases and controls were visited at home and interviewed using a validated questionnaire. Cases and controls were compared in terms of socio-demographic, economic and other variables. RESULTS: Participants with less than secondary school education were more likely to be non-compliant (odds ratio [OR], 2.51, 95% confidence interval [CI], 1.06- 5.97), while participants who were aware of legislation against non-compliance with immunization (OR, 0.35; 95% CI, 0.17, 0.69) were less likely to fail to immunize their children. CONCLUSION: Policy-makers and programme managers need to use established educational and communication channels to increase awareness of childhood immunization especially among families with lower educational levels in the parish.

Factors associated with arterial vascular events in PROFILE: a Multiethnic Lupus Cohort.

The objective of this study was to determine the factors associated with the occurrence of arterial vascular events in a multiethnic systemic lupus erythematosus (SLE) cohort. The PROFILE cohort, comprised SLE patients (n = 1333) of defined ethnicity from five different US institutions, was studied to determine demographic, clinical and biological variables associated with vascular events. An arterial vascular event (first episode) was either a myocardial infarction, angina pectoris and/or a vascular procedure for myocardial infarction, stroke, claudication and/or evidence of gangrene. Patient characteristics were analyzed by univariable and multivariable Cox proportional hazards regression analyses. One-hundred twenty-three (9.8%) patients had at least one incident arterial event. Age at cohort enrollment (HR = 1.04, 95% CI 1.03-1.06), smoking (HR = 2.20, 95% CI 1.40-3.46) and the CRP2* C alleles (HR = 1.91, 95% CI 1.04-3.49) were associated with a shorter time-to-the occurrence of arterial vascular events. Some clinical manifestations of disease activity were associated with a shorter time-to-occurrence [psychosis (HR = 2.21, 95% CI 1.10-4.44), seizures (HR = 1.85, 95% CI 1.00-3.24) and anaemia (HR = 1.83, 95% CI 1.02-3.31)], but others were not [arthritis (HR = 0.32, 95% CI 0.18-0.58)]. In conclusion, older patients, especially in the context of a predisposing environmental factor (smoking) and severe clinical manifestations, are at higher risk of having arterial vascular events. The genetic contribution of the variation at the CRP locus was not obscured by demographic or clinical variables. Awareness of these factors should lead to more effective management strategies of patients at risk for arterial vascular events.
