ABSTRACT
BACKGROUND: Racism is a social determinant of health inequities and associated with poorer health and health behaviors. As a domain of racism, self-reported racial discrimination affects health through unhealthy behaviors (e.g., smoking) but the understudied impact of self-reported racial discrimination's relationship with healthy behaviors (e.g., cancer screening) precludes a comprehensive understanding of racism's impact on health inequities. Understanding how self-reported racial discrimination impacts healthy behaviors is even more important for those living in rural persistent poverty areas (poverty rates of 20% or more of a population since 1980), who have a higher disease burden due to poverty's interaction with racism. The distinct sociocultural context of rural persistent poverty areas may result in differential responses to self-reported racial discrimination compared to those in non-persistent poverty areas. METHODS: A community-engaged process was used to administer a survey to a convenience sample of 251 Black adults residing in 11 rural persistent poverty counties in the state of Arkansas. Self-reported racial discrimination, fruit and vegetable intake, colorectal cancer screening, cervical cancer screening, and screening mammography were assessed. Stress and religion/spirituality were also assessed as potential mediators or moderators in the relationship between self-reported racial discrimination and healthy behaviors. RESULTS: In adjusted models, those reporting more self-reported racial discrimination had a higher probability of having had a test to check for cervical cancer (situation discrimination: OR = 1.23, 95% CI: 1.04-1.5; frequency discrimination: OR = 1.06, 95% CI: 1.02-1.12). Stress and religion/spirituality were not significant mediators/moderators. DISCUSSION: Greater self-reported racial discrimination was associated with a higher odds of cervical cancer screening. Black adults residing in rural persistent poverty areas may have greater self-reported racial discrimination-specific coping and racial identity attitudes.
ABSTRACT
This case represents an impressive finding of a young male who developed cutaneous sarcoid-like reactions that arose secondarily to tattoo ink. Cutaneous manifestations of sarcoidosis can present themselves in various ways, be caused by different inducing factors, and may present themselves not only cutaneously but as one of the many findings of systemic sarcoidosis. A 24-year-old black gentleman presented to the dermatology clinic with a manifestation of papules in his tattoos that covered a majority of his body. The patient tried hypoallergenic tattoo ink to see if this would prevent the formation of these bumps; however, this only further provoked the production of these papules confined to tattooed areas. Skin findings revealed linear raised papules in a continuous fashion in areas where the patient had tattoo ink on his torso, bilateral arms and legs, and face. At presentation, he denied any constitutional, pulmonary, or ophthalmologic symptoms. Pathological findings revealed sarcoidal granulomatous dermatitis showing nodular non-necrotizing granulomatous inflammatory infiltrate involving the superficial and deep dermis. The patient was then evaluated by pulmonology to rule out any systemic findings of sarcoidosis, which showed a negative chest x-ray. The patient was started on oral prednisone and topical pimecrolimus cream, and when he returned for his one-month follow-up, there were minimal to no visible cutaneous lesions. Tattoo ink has been shown to cause a variety of cutaneous reactions such as infections, neoplasms, and inflammatory dermatoses such as eczema, lichen planus, psoriasis, vitiligo, and sarcoidosis. Cutaneous sarcoid-like reactions secondary to tattoo ink are rare findings; however, they must be taken seriously due to the risk of systemic sarcoidosis involvement both at initial presentation and in the future.
ABSTRACT
Background: Psychological trauma is a highly prevalent driver of poor health among people with HIV (PWH) in the Southern United States (U.S.). Trauma-informed care (TIC) has potential to advance national Ending the HIV Epidemic (EHE) goals, but formative research is needed to tailor TIC implementation to complex and interdependent HIV networks. Methods: We applied a community-based participatory research (CBPR) approach to iteratively engage personnel from high volume HIV care institutions in Nashville, Tennessee. Current practices and potential implementation determinants were identified through participatory process mapping (PM) and key informant interviews. The Consolidated Framework for Implementation Research (CFIR) was applied to deductively code interview data. Personnel attending a dissemination summit developed a network-wide implementation plan. Results: Data were collected with personnel from five institutions (e.g., community-based organizations, primary care clinics, public health department), for PM (n=48), interviews (n=35), and the summit (n=17). Results suggest there are limited trauma screenings, assessments, and services across the network. Relevant Characteristics of Individuals included a trauma-sensitive workforce committed to continuous learning and TIC adoption. Relevant Inner Setting Factors were networks and communications, with strong tension for change, high compatibility with TIC, and need for advancing cultural responsiveness. Relevant Outer Setting Factors included patient needs and resources and cosmopolitanism, with need for better leveraged mental health services. Relevant Process domains were champions and leadership, with need to diversify championship among leaders. Relevant Intervention Characteristics included relative advantage and complexity, with need for personnel wellness initiatives and increased engagement with the community as service designers. Four recommendations included development of shared communication systems, personnel wellness campaigns, routine evaluations to inform practices, and culturally responsive care initiatives. Conclusion: Modifiable TIC determinants were identified, and a community-created implementation plan was developed to guide adoption. Future research will focus on city-wide implementation and strengthening pre-implementation research in other settings.
ABSTRACT
OBJECTIVE: To develop updated guidelines for the perioperative management of disease-modifying medications for patients with rheumatic diseases, specifically those with inflammatory arthritis (IA) and those with systemic lupus erythematosus (SLE), undergoing elective total hip arthroplasty (THA) or elective total knee arthroplasty (TKA). METHODS: We convened a panel of rheumatologists, orthopedic surgeons, and infectious disease specialists, updated the systematic literature review, and included currently available medications for the clinically relevant population, intervention, comparator, and outcomes (PICO) questions. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the quality of evidence and the strength of recommendations using a group consensus process. RESULTS: This guideline updates the 2017 recommendations for perioperative use of disease-modifying antirheumatic therapy, including traditional disease-modifying antirheumatic drugs, biologic agents, targeted synthetic small-molecule drugs, and glucocorticoids used for adults with rheumatic diseases, specifically for the treatment of patients with IA, including rheumatoid arthritis and spondyloarthritis, those with juvenile idiopathic arthritis, or those with SLE who are undergoing elective THA or TKA. It updates recommendations regarding when to continue, when to withhold, and when to restart these medications and the optimal perioperative dosing of glucocorticoids. CONCLUSION: This updated guideline includes recently introduced immunosuppressive medications to help decision-making by clinicians and patients regarding perioperative disease-modifying medication management for patients with IA and SLE at the time of elective THA or TKA.

BACKGROUND: Glucose-6-phosphate dehydrogenase deficiency (G6PD) is linked to hemolytic anemia with certain medications and is the most common enzyme deficiency worldwide. Although the American College of Rheumatology does not recommend routine testing for G6PD prior to initiation of hydroxychloroquine (HCQ), the package insert for HCQ does recommend careful use in patients with G6PD deficiency. METHODS: We identified eligible subjects seen at our tertiary care, urban medical center between 1997 and 2018. Case records were analyzed for G6PD deficiency, HCQ use, length of exposure to HCQ, demographic characteristics, and laboratory evidence of hemolysis. RESULTS: We found 5264 patients who were prescribed HCQ, of which 49.5% (2605 patients) were screened for G6PD deficiency. Of the screened patients, 36 were found to be G6PD-deficient. Of the G6PD-deficient patients, 18 were exposed to HCQ. No evidence of hemolysis was found in these exposed patients. CONCLUSIONS: Despite more than 500 months of cumulative exposure time to HCQ, there were no cases of hemolysis. These findings are in line with recently published data and suggest that this interaction is not associated with clinically significant hemolysis in our population of mainly African American and Hispanic patients. Limitations to our study are potential bias due to case review design and lack of prior assessment of episodes of hemolysis before HCQ exposure. A high proportion of our patients were Hispanic, suggesting no increase of adverse events in this subgroup. A larger longitudinal trial would be needed to definitively answer the question of the safety of HCQ in G6PD-deficient patients.

OBJECTIVES: The use of ultrasound (US) guidance for the injection and aspiration of joints has improved accuracy. The aim of this study was to determine if differences exist in the level of patient satisfaction, functionality, and the quality of life in adult patients receiving US-guided (USG) versus landmark-guided (LMG) knee procedures. METHODS: This prospective, randomized study enrolled 41 patients undergoing knee procedures to USG or LMG groups. visual analogue scale (VAS) for pain, knee injury and osteoarthritis outcome score (KOOS), and patient satisfaction score on a 5-point Likert scale were measured pre-procedure, immediate (< 30 min) and late (4-6 weeks) post-procedure. RESULTS: Thirty-seven patients were included in the final analysis after exclusion of 4 dropouts (18 in LMG arm, 19 in USG arm). Compared with LMG group, patients in the USG group had significantly better improvement in pain immediately (VAS 1.63 ± 1.6 (95% CI 0.91, 2.35) vs 4.05 ± 2.5 (95% CI 2.90, 4.62), p = 0.001) and later post-procedure (VAS 2.68 ± 2.0 (95% CI 1.78, 3.58) vs 6.38 ± 3.8 (95% CI 4.62, 8.14) p = 0.004) and satisfaction scores immediately (4.89 ± 0.3 (95% CI 4.76, 5.02) vs 4.11 ± 1.0 (95% CI 3.65, 4.57), p = 0.002) as well as delayed post-procedure (4.52 ± 0.9 (95% CI 4.12, 4.92) vs 3.38 ± 1.6 (95% CI 2.64, 4.12), p = 0.028). CONCLUSION: USG knee procedures were associated with higher patient satisfaction, both immediately after the procedure and after 4-6 weeks compared with LMG knee procedures. Key Points â¢This prospective study is the first one to look at patient satisfaction as an outcome measure after intra-articular steroids knee injections. â¢USG (US-guided) knee procedures were associated with higher patient satisfaction compared with LMG (landmark-guided) knee procedures. â¢USG knee procedures resulted in greater improvement in symptoms, pain, and quality of life scales after 4-6 weeks compared with LMG knee procedures.

Melasma is a common pigmentation disorder with few satisfactory treatment options. The hyperpigmentation has both an epidermal and dermal component. To date, combination therapies have been observed to yield greater improvements in melasma compared to monotherapies. Cysteamine has been tested and shown to improve epidermal melasma. In this case series, we examined the efficacy of nightly applications of cysteamine cream, washed off after 15 minutes, with monthly in-office laser treatment sessions using a 650-microsecond neodymium-doped yttrium aluminium garnet 1,064-nm laser. The patients all reported satisfaction with the results of this combination therapy. None of the patients experienced irritation with the product nor did they experience discomfort/downtime with the laser sessions. Evaluation of the patients two months after the treatment indicated persisting effects. Our small case series suggests high levels of satisfaction can be achieved using this combined topical and laser approach.
ABSTRACT
Haemophagocytic lymphohistiocytosis (HLH) is a potentially life-threatening syndrome caused by excessive immune activation. Secondary HLH has been described in autoimmune diseases. We detail the case of a 28-year-old African American woman who developed HLH in the setting of systemic lupus erythematosus with collapsing lupus podocytopathy superimposed on mesangial proliferative lupus nephritis class II. Genotyping for APOL1 risk alleles revealed the presence of double (G1/G2) risk alleles. Our patient achieved a complete renal recovery and resolution of HLH within 1 month of treatment with steroids and mycophenolate mofetil, highlighting the importance of prompt, aggressive therapy.

BACKGROUND: To identify major obstacles to appointment compliance and quantify a measurable effect of a simple phone call intervention on the clinic show rate. METHODS: We retrospectively looked at the show rates from November 1st, 2013 to June 30th, 2014 at our Lupus clinic, which is located in Bronx, NY. The scheduled patient chart was crosschecked if the patient made it to the appointment by verifying the provider note. A patient survey was implemented over a period of 8 weeks from July 1st, 2014 to August 12th, 2014. A reminder phone call intervention 2-3 days prior to the visit was planned. The intervention was implemented from September 1st, 2014 to April 30th, 2015. Data was analyzed after the end of the intervention period. RESULTS: In the pre-intervention period, our clinic show-rate was 207/352 (58.8%) The pilot survey had a total of 43 responses. The most common reason for a missed appointment was 'forgot about the appointment' (45.5%). Reminder phone calls were the preferred intervention (76.74%), which patients' thought might help to keep scheduled appointments. In the intervention period, 283 of the scheduled 378 appointments were completed (74.8) in the lupus clinic. The difference in the show rate before and after the intervention by Pearson's Chi-squared test with Yates continuity correction was statistically significant with a p-value of 0.0062. CONCLUSION: A simple telephone call reminder significantly improves clinic show rates in an underserved Lupus clinic, which can help improve health parameters in the Lupus population.

OBJECTIVE: This collaboration between the American College of Rheumatology and the American Association of Hip and Knee Surgeons developed an evidence-based guideline for the perioperative management of antirheumatic drug therapy for adults with rheumatoid arthritis (RA), spondyloarthritis (SpA) including ankylosing spondylitis and psoriatic arthritis, juvenile idiopathic arthritis (JIA), or systemic lupus erythematosus (SLE) undergoing elective total hip (THA) or total knee arthroplasty (TKA). METHODS: A panel of rheumatologists, orthopedic surgeons specializing in hip and knee arthroplasty, and methodologists was convened to construct the key clinical questions to be answered in the guideline. A multi-step systematic literature review was then conducted, from which evidence was synthesized for continuing versus withholding antirheumatic drug therapy and for optimal glucocorticoid management in the perioperative period. A Patient Panel was convened to determine patient values and preferences, and the Grading of Recommendations Assessment, Development and Evaluation methodology was used to rate the quality of evidence and the strength of recommendations, using a group consensus process through a convened Voting Panel of rheumatologists and orthopedic surgeons. The strength of the recommendation reflects the degree of certainty that benefits outweigh harms of the intervention, or vice versa, considering the quality of available evidence and the variability in patient values and preferences. RESULTS: The guideline addresses the perioperative use of antirheumatic drug therapy including traditional disease-modifying antirheumatic drugs, biologic agents, tofacitinib, and glucocorticoids in adults with RA, SpA, JIA, or SLE who are undergoing elective THA or TKA. It provides recommendations regarding when to continue, when to withhold, and when to restart these medications, and the optimal perioperative dosing of glucocorticoids. The guideline includes 7 recommendations, all of which are conditional and based on low- or moderate-quality evidence. CONCLUSION: This guideline should help decision-making by clinicians and patients regarding perioperative antirheumatic medication management at the time of elective THA or TKA. These conditional recommendations reflect the paucity of high-quality direct randomized controlled trial data.

A mixing model derived from first principles describes the bulk density (BD) of intertidal wetland sediments as a function of loss on ignition (LOI). The model assumes that the bulk volume of sediment equates to the sum of self-packing volumes of organic and mineral components or BD = 1/[LOI/k1 + (1-LOI)/k2], where k1 and k2 are the self-packing densities of the pure organic and inorganic components, respectively. The model explained 78% of the variability in total BD when fitted to 5075 measurements drawn from 33 wetlands distributed around the conterminous United States. The values of k1 and k2 were estimated to be 0.085 ± 0.0007 g cm-3 and 1.99 ± 0.028 g cm-3, respectively. Based on the fitted organic density (k1) and constrained by primary production, the model suggests that the maximum steady state accretion arising from the sequestration of refractory organic matter is ≤ 0.3 cm yr-1. Thus, tidal peatlands are unlikely to indefinitely survive a higher rate of sea-level rise in the absence of a significant source of mineral sediment. Application of k2 to a mineral sediment load typical of East and eastern Gulf Coast estuaries gives a vertical accretion rate from inorganic sediment of 0.2 cm yr-1. Total steady state accretion is the sum of the parts and therefore should not be greater than 0.5 cm yr-1 under the assumptions of the model. Accretion rates could deviate from this value depending on variation in plant productivity, root:shoot ratio, suspended sediment concentration, sediment-capture efficiency, and episodic events.
ABSTRACT
OBJECTIVE: Although new treatments for rheumatoid arthritis (RA) are extremely effective in preventing disease progression, rates of total knee replacement (TKR) continue to rise. The ongoing need for TKR is problematic, especially as functional outcomes in patients with RA have been reported to be worse than in patients with osteoarthritis (OA). The purpose of this study is to assess pain, function, and quality of life 2 years after TKR in contemporary patients with RA compared with patients with OA. METHODS: Primary TKR cases enrolled between May 1, 2007 and July 1, 2010 in a single institution TKR registry were eligible for this study. Validated RA cases were compared with OA at baseline and at 2 years. RESULTS: We identified 4456 eligible TKR, including 136 RA. Compared with OA, RA TKR had significantly worse preoperative Western Ontario and McMaster Universities Osteoarthritis Index pain (55.9 vs 46.6, p < 0.0001) and function (58.7 vs 47.3, p < 0.0001); however, there were no differences at 2 years. Within RA, there was no difference for patients who were treated with biologic disease-modifying antirheumatic drugs versus those who did not in pain (p = 0.41) or function (p = 0.39) at 2 years. In a multivariate regression, controlling for multiple potential confounders, there was no independent association of RA with 2-year pain (p = 0.18) or function (p = 0.71). Satisfaction was high for both RA and OA. CONCLUSION: Patients with RA undergoing primary TKR have excellent 2-year outcomes, comparable with OA, in spite of worse preoperative pain and function. In this contemporary cohort, RA is not an independent risk factor for poor outcomes.
