RESUMO

BACKGROUND: Convalescent plasma has been widely used to treat coronavirus disease 2019 (Covid-19) under the presumption that such plasma contains potentially therapeutic antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that can be passively transferred to the plasma recipient. Whether convalescent plasma with high antibody levels rather than low antibody levels is associated with a lower risk of death is unknown. METHODS: In a retrospective study based on a U.S. national registry, we determined the anti-SARS-CoV-2 IgG antibody levels in convalescent plasma used to treat hospitalized adults with Covid-19. The primary outcome was death within 30 days after plasma transfusion. Patients who were enrolled through July 4, 2020, and for whom data on anti-SARS-CoV-2 antibody levels in plasma transfusions and on 30-day mortality were available were included in the analysis. RESULTS: Of the 3082 patients included in this analysis, death within 30 days after plasma transfusion occurred in 115 of 515 patients (22.3%) in the high-titer group, 549 of 2006 patients (27.4%) in the medium-titer group, and 166 of 561 patients (29.6%) in the low-titer group. The association of anti-SARS-CoV-2 antibody levels with the risk of death from Covid-19 was moderated by mechanical ventilation status. A lower risk of death within 30 days in the high-titer group than in the low-titer group was observed among patients who had not received mechanical ventilation before transfusion (relative risk, 0.66; 95% confidence interval [CI], 0.48 to 0.91), and no effect on the risk of death was observed among patients who had received mechanical ventilation (relative risk, 1.02; 95% CI, 0.78 to 1.32). CONCLUSIONS: Among patients hospitalized with Covid-19 who were not receiving mechanical ventilation, transfusion of plasma with higher anti-SARS-CoV-2 IgG antibody levels was associated with a lower risk of death than transfusion of plasma with lower antibody levels.

RESUMO

Premortem clinical presentation of cancer-associated non-bacterial thrombotic endocarditis (Ca-NBTE), therapy, and the clinal course is limited to case reports and small clinical series. An electronic search of Mayo Clinic records (03/31/2002-06/30/2022) with a subsequent manual review was performed to identify adult patients with echocardiographically detected NBTE and active malignancy, excluding those with infectious endocarditis or lupus anticoagulant/antiphospholipid antibodies. In this retrospective cohort study, we analyzed 115 Ca-NBTE patients (mean age 63.2 ± 9.7 years, 66.1% female) involving 71 (61.7%) mitral, 58 (50.4%) aortic, 8 (6.9%) tricuspid, and 1 (0.9%) pulmonary valve. The most common cancer was lung (n = 45 cases (39.1%), followed by pancreatic (n = 19, 16.5%), gynecological (17, 14.8%), gastrointestinal (n = 10, 8.7%), and 10 (8.7%) with hematologic malignancy; 6 patients had two active cancers. Embolic complications at presentation were frequent: 94 (81.7%) brain, 11 splenic, 10 renal, 6 coronary, and 4 to the extremities. Of 104 anticoagulated patients, 60 received low molecular weight heparin, 17 unfractionated heparin, 16 apixaban, 8 warfarin, and 3 rivaroxaban. There were 18 arterial thromboembolisms; the Kaplan-Meier estimates of the incidence at 2 years were consistent with a rate of 15.9% [95% Confidence Interval (CI) 9.9-23.3], including 14 strokes (12.4%, 95%CI, 7.1-19.2), and 8 other arterial emboli (10.5%, 95%CI, 4.7-18.9); there were 10 venous thromboembolisms (8.9%, 95%CI, 4.5-15.0). Fourteen major bleedings occurred (12.8%, 95%CI, 7.3-19.9) and 94 patients died during follow-up (77.9%, 95%CI, 71.1-85.8). Ca-NBTE predominantly affected women with lung adenocarcinoma or digestive tract cancers and manifested by stroke with high mortality and frequent embolic and bleeding complications during anticoagulation therapy.

RESUMO

BACKGROUND: Simultaneous liver kidney (SLK) transplant protects against acute cellular rejection. In 2017, UNOS implemented a "safety net" policy to allow patients with renal recovery to avoid renal transplantation. Whether kidney after liver transplantation (KALT) increases the risk of rejection is unknown. METHODS: We performed a retrospective analysis of the Organ Procurement and Transplantation Network (OPTN) database of adult patients who received liver transplant, SLK or KALT between 2010 and 2020. We examined rejection of the liver within 6 months and 1 year of the liver transplant, as well as rejection of the kidney within 6 months and 1 year of receiving the kidney, as well as patient and graft loss. RESULTS: Sixty-six thousand seventy-nine patients were transplanted; 60 168 with liver transplant alone, 5627 with SLK, and 284 with KALT. Acute or chronic liver rejection rates within 6 or 12 months were statistically higher in the KALT group (10.0% and 10.9%) compared to the SLK group (6.1% and 7.5%), but comparable to the LTA group (9.3% and 11.1%). Kidney rejection and graft survival rates were not different. Liver graft survival was worse in KALT than SLK or LTA (Kaplan-Meier estimates .61 vs. .89 and .90), but these patients were more ill at the time of transplantation. KDPI and LDRI scores were notably lower in the SLK than KALT group. Patient survival was not clinically different between the groups. CONCLUSION: KALT does not increase the risk of acute or chronic kidney rejection. SLK has a lower risk of early liver rejection, but this effect diminishes by one year to being not clinically different compared to KALT. Given that KALT is immunologically safe, and potentially avoids unnecessary renal graft use, it should be preferred over SLK. BRIEF SUMMARY: Patients undergoing sequential kidney after liver transplant do not have an increased risk of liver or kidney rejection when compared to liver transplant alone or simultaneous liver and kidney transplant.

RESUMO

OBJECTIVE: To determine the association between pre-operative central subfield thickness (CST) and post-radiotherapy visual acuity (VA), cystoid macular edema (CME), and intravitreal anti-vascular endothelial growth factor (VEGF) requirement. DESIGN: Single-center retrospective study. PARTICIPANTS: Patients with plaque-irradiated extramacular choroidal melanoma treated between 11/11/2011 and 4/30/2021. Pre-operative CST difference between the affected and unaffected eye was used. Kaplan-Meier analysis and hazard ratios were calculated. RESULTS: Of 85 patients, pre-operative CST was greater in the melanoma-affected eye (vs. fellow eye) by mean of 20.4 µm (median 14.0, range - 60.0-182.0). Greater CST at presentation (vs. fellow eye) was associated with larger tumor diameter (p = 0.02), greater tumor thickness (p < 0.001), and more frequent tumor-related Bruch's membrane rupture (p = 0.006). On univariate analysis of outcome data, greater CST at presentation (vs. fellow eye) was associated with higher 5-year risk (1.09 [1.02-1.17], p = 0.02) of VA 20/200 or worse and increased (1.10 [1.01-1.20], p = 0.03) likelihood for anti-VEGF injections after plaque irradiation. There was no significant association with CME. The association between CST and VA outcome remained significant on multivariate analysis accounting for impact of tumor thickness and radiation dose to optic disc, while tumor distance to fovea was the only significant factor on multivariate analysis for anti-VEGF injections. CONCLUSION: Greater CST at presentation (vs. fellow eye) was associated with worse VA outcome following plaque radiotherapy for choroidal melanoma. Large-sized tumors may contribute to a higher intraocular VEGF burden, potentially leading to greater preoperative CST, which correlates with poor VA outcome post-plaque radiotherapy.

RESUMO

BACKGROUND: Vitreoretinal lymphoma (VRL) is a rare intraocular malignancy that poses a diagnostic challenge due to the non-specific clinical presentation that resembles uveitis. The use of spectral domain optical coherence tomography (SD-OCT) has emerged as a valuable imaging tool to characterize VRL. Therefore, we sought to determine the specific OCT features in VRL compared to the uveitides. METHODS: Retrospective chart review of patients who were seen at Mayo Clinic from January 1, 2010 through December 31, 2022. The medical records and SD-OCT images at time of initial presentation were reviewed in patients with biopsy-proven VRL, intermediate uveitis, or biopsy-confirmed sarcoid posterior uveitis. Patients with VRL or similar uveitides including intermediate uveitis or sarcoid posterior uveitis were included. RESULTS: There were 95 eyes of 56 patients in the VRL group and 86 eyes of 45 patients in the uveitis group, of whom 15 (33.3%) were diagnosed with intermediate uveitis and 30 (66.7%) with sarcoid chorioretinitis. The SD-OCT features more commonly seen at initial presentation in VRL patients (vs. uveitis) included preretinal deposits (31.6% vs. 9.3%, p = 0.002), intraretinal infiltrates (34% vs. 3.5%, p < 0.001), inner retinal hyperreflective spots (15.8% vs. 0%, p < 0.001), outer retinal atrophy (22.1% vs. 2.3%, p < 0.001), subretinal focal deposits (21.1% vs. 4.7%, p = 0.001), retinal pigmented epithelium (RPE) changes (49.5% vs. 3.5%, p < 0.001), and sub-RPE deposits (34.7% vs. 0%, p < 0.001). Features more frequently seen in uveitis included epiretinal membrane (ERM) (82.6% vs. 44.2%, p < 0.001), central macular thickening (95.3% vs. 51.6%, p < 0.001), cystoid macular edema (36% vs. 11.7%, p < 0.001), subretinal fluid (16.3% vs 6.4%, p = 0.04), and subfoveal fluid (16.3% vs. 3.2%, p = 0.003). Multivariate regression analysis controlling for age and sex showed absence of ERM (OR 0.14 [0.04,0.41], p < 0.001) and absence of central macular thickening (OR 0.03 [0,0.15], p = 0.02) were associated with VRL as opposed to uveitis. CONCLUSION: OCT features most predictive of VRL (vs. uveitis) included absence of ERM and central macular thickening.

RESUMO

BACKGROUND: This study aims to determine the population-based incidence and characterize the features of nonarteritic anterior ischemic optic neuropathy (NAION) using the Rochester Epidemiology Project (REP). METHODS: All patients diagnosed with an optic neuropathy from January 1, 1990, to December 31, 2016, were retrospectively reviewed to identify incident cases of NAION using the REP database, which is a record-linkage system of medical records for all patient-physician encounters among Olmsted County, Minnesota residents. The overall incidence of NAION was estimated using the age-specific and sex-specific population figures for Olmsted County census data for 1990 through 2016. Visual outcomes and risk factors were evaluated. The systemic risk factors were compared with age-matched controls. RESULTS: One hundred four patients were diagnosed with NAION during the 26-year study period. The overall age and sex adjusted incidence was 3.89 per 100,000 individuals (95% confidence interval [CI]: 3.14-4.65). The incidence was 7.73 (CI: 6.24-9.22) in patients aged 40 years or older and 10.19 (CI: 8.15-12.23) in patients aged 50 years or older. Median age at diagnosis was 65 years (range, 40-90 years), and 59 (56.7%) were male. The median logMAR visual acuity at presentation was 0.35 (Snellen equivalent of 20/40) with 14 patients (13.5%) having vision of counting fingers or worse. Among the 91 patients with final visual acuity outcome data available, the median visual acuity was 0.40 (Snellen equivalent of 20/50) with 12 patients (13.2%) having vision of counting fingers or worse. Twenty-four patients (26.4%) were noted to have final acuity at least 3 Snellen lines worse than at presentation, whereas 17 patients (18.7%) were noted to improve by at least 3 lines. The median mean deviation on automated visual field testing was -10.2 dB at presentation and -11.1 dB at follow-up. Twenty-two patients (21.2%) suffered NAION in the fellow eye; the median interval between involvement of the first and second eyes was 1.39 years. Systemic diseases present in the NAION cohort included hypertension (79.8%), diabetes mellitus (39.4%), obstructive sleep apnea (23.1%), and hyperlipidemia (74.0%), which were all statistically higher than age-matched controls. CONCLUSIONS: NAION is a relatively common optic neuropathy in elderly patients with vascular risk factors. Our data indicate that the incidence of NAION has remained relatively stable in the population of Olmsted County over the past 4 decades.

RESUMO

PURPOSE: This study investigates how Obstructive sleep apnea (OSA) affects the outcomes of ptosis repair. We hypothesized that patients with OSA have an increased rate of reoperation after ptosis repair. METHODS: This retrospective cohort study included patients age >18 from the Mayo Clinic who underwent ptosis repair by levator advancement or Müller muscle-conjunctiva resection between 2018 and 2021. Outcomes were measured at 1 to 3 months of follow-up with surgical failure defined as asymmetry or unsatisfactory eyelid height requiring revision surgery within 1 year. RESULTS: A total of 577 patients met the inclusion criteria. There was a statistically significant difference in surgical failure between patients with OSA and those without (20.5% vs. 13.1%, p = 0.02). Patients with OSA showed a statistically significant difference in risk of revision by a factor of 1.70 (95% CI: 1.06-2.07). Revisions were attributed to unsatisfactory eyelid height in 72.6% of patients and eyelid asymmetry in 21.1%. All patients who had revision surgery had satisfactory outcomes. On logistic regression analysis, when adjusting for age and sex, OSA was significantly associated with ptosis revision ( p = 0.007). CONCLUSIONS: OSA increases risk of surgical failure and need for revision surgery in patients undergoing blepharoptosis repair but is not a sole risk factor.

RESUMO

OBJECTIVE: This mixed methods study examined depictions of spirituality among people with psychosis in influential television programming. Spirituality is a central strength for many people with psychosis. Yet, despite the important role media plays in shaping perceptions, little research has examined the intersection between spirituality and psychosis in popular media. METHODS: To address this gap, we conducted a content analysis of the 50 most viewed primetime fictional television shows over a 10-year period as determined by the Nielsen rating organization. Characters with psychosis were identified via keyword searches of online sources (wikis, IMDb, etc.) and subsequently independently coded by two individuals. Characters were rated on 18 items in three domains related to demographics, life status, and character framing. Inter-rater reliability ranged from good to excellent across variables. RESULTS: Of 120 identified focal characters with psychosis, just 16 percent (n = 19) had a spiritual identity. Analysis revealed few differences between spiritual and secular characters on demographic and life status variables. Conversely, an examination of framing variables revealed spiritual characters were comparatively less attractive, exhibited a greater negative impact on society, and were more likely to be referred to pejoratively (as a psychopath) and engage in criminal activity. Trend analysis indicated portrayals of spiritual characters decreased over time. CONCLUSIONS: The results suggest media depictions of spirituality contribute to the stigmatization of spirituality among people with psychosis, potentially mitigating access to important coping resources and discouraging professional help-seeking. Primary care physicians should consider incorporating a spiritual assessment into care to operationalize spiritual coping assets.

RESUMO

OBJECTIVE: The aims of this study were to assess whether a relationship between anti-SSA-52 and interstitial lung disease (ILD) can be further defined, and to enhance screening, detection, and potentially guide treatment. METHODS: A historical cohort study of 201 patients was conducted at a single tertiary care center between January 1, 2016 and December 31, 2020. All included patients were anti-SSA-52 antibody positive. Chart review was performed for laboratory values, symptoms, pulmonary function tests, treatment, and imaging. Chest computed tomographies were reviewed by chest radiologists. RESULTS: Among anti-SSA-52 antibody-positive patients, ILD was found in 125 (62.2%) compared with 76 (37.8%) with no ILD (p = 0.001). For those with ILD, 78 (62.4%) were diagnosed with connective tissue disease (CTD)-associated ILD, 28 (22.4%) were diagnosed ILD only, and 19 (15.2%) met the criteria for interstitial pneumonia with autoimmune features. In patients with CTD-ILD, 18 (23.0%) had their ILD diagnosis made over 6 months before a CTD diagnosis, and an additional 43 (55.1%) had their ILD and CTD diagnosed within 6 months of each other (p < 0.001). Common computed tomography patterns were nonspecific interstitial pneumonia/organizing pneumonia overlap in 44 (35.2%), 25 (20.0%) nonspecific interstitial pneumonia, and 15 (12%) usual interstitial pneumonia. Twenty-eight (35.9%) had antisynthetase syndrome, followed by 16 (20.5%) with dermatomyositis, 10 (12.8%) with CTD overlap, and 6 (7.7%) with systemic scleroderma. CONCLUSIONS: There was a significant association between anti-SSA-52 antibodies and ILD across a wide spectrum of rheumatological diagnoses. A significant portion of patients were diagnosed with ILD either at the same time or before their CTD diagnosis. Further study will be needed to assess effective treatment and response.

RESUMO

The two aims of this study were to: 1) identify the 100 most impactful contributors to English-language gerontological journals, and 2) map their respective disciplinary affiliations to help illuminate the perspectives shaping gerontological discourse. Toward that end, we conducted a secondary data analysis of a publicly available database of the world's leading scientists. After extracting all scientists in the gerontological category, we rank ordered them according to a composite measure of scholarly impact that controls for self-citations and author order while also calculating other bibliometric statistics. Disciplinary affiliations were assigned based upon the Classification of Instructional Programs codes developed by the National Center for Education Statistics at the United States Department of Education. The results reveal the mean contributor to the gerontological literature published 241.15 (SD = 203.95) papers and - after correcting for self-citations - had an h-index of 50.05 (SD = 25.00), and an hm-index 23.67 (SD = 7.50). A diverse array of professional affiliations characterized the contributors with a plurality being located in the health professions category, followed by the biological and biomedical science, and social sciences categories. The results reveal that gerontology is home to some of the world's leading scientists. Leveraging their expertise can help advance the field's collective knowledge development.

RESUMO

BACKGROUND: There are good data to support using a single high-sensitivity cardiac troponin T (hs-cTnT) below the limit of detection of 5 ng/L to exclude acute myocardial infarction. Per the US Food and Drug Administration, hs-cTnT can only report to the limit of quantitation of 6 ng/L, a threshold for which there are limited data. Our goal was to determine whether a single hs-cTnT below the limit of quantitation of 6 ng/L is a safe strategy to identify patients at low risk for acute myocardial injury and infarction. METHODS: The efficacy (proportion identified as low risk based on baseline hs-cTnT<6 ng/L) of identifying low-risk patients was examined in a multicenter (n=22 sites) US cohort study of emergency department patients undergoing at least 1 hs-cTnT (CV Data Mart Biomarker cohort). We then determined the performance of a single hs-cTnT<6 ng/L (biomarker alone) to exclude acute myocardial injury (subsequent hs-cTnT >99th percentile in those with an initial hs-cTnT<6 ng/L). The clinically intended rule-out strategy combining a nonischemic ECG with a baseline hs-cTnT<6 ng/L was subsequently tested in an adjudicated cohort in which the diagnostic performance for ruling out acute myocardial infarction and safety (myocardial infarction or death at 30 days) were evaluated. RESULTS: A total of 85 610 patients were evaluated in the CV Data Mart Biomarker cohort, among which 24 646 (29%) had a baseline hs-cTnT<6 ng/L. Women were more likely than men to have hs-cTnT<6 ng/L (38% versus 20%, P<0.0001). Among 11 962 patients with baseline hs-cTnT<6 ng/L and serial measurements, only 1.2% developed acute myocardial injury, resulting in a negative predictive value of 98.8% (95% CI, 98.6-99.0) and sensitivity of 99.6% (95% CI, 99.5-99.6). In the adjudicated cohort, a nonischemic ECG with hs-cTnT<6 ng/L identified 33% of patients (610/1849) as low risk and resulted in a negative predictive value and sensitivity of 100% and a 30-day rate of 0.2% for myocardial infarction or death. CONCLUSIONS: A single hs-cTnT below the limit of quantitation of 6 ng/L is a safe and rapid method to identify a substantial number of patients at very low risk for acute myocardial injury and infarction.

RESUMO

The number of kidney after liver transplants (KALT) increased after the implementation of the United Network of Organ Sharing (UNOS) safety net policy, but the effects of the policy on KALT outcomes remain unknown. Using the UNOS database, we identified KALT between 60 and 365 days from liver transplant from January 1, 2010, to December 31, 2020. The main outcome was 1- and 3-year patient, liver, and kidney graft survival. Secondary outcomes included 6-month and 1-year acute rejection (AR) of liver and kidney, and 1-year kidney allograft function. Of the 256 KALT, 90 were pre-policy and 166 post-policy. Compared to pre-policy, post-policy 1- and 3-year liver graft survival was higher (54% and 54% vs. 86% and 81%, respectively, p <0.001), while 1- and 3-year kidney graft survival (99% and 75% vs. 92% and 79%, respectively, p =0.19), and 1- and 3-year patient survival (99% and 99% vs. 95% and 89%, respectively, p =0.11) were not significantly different. Subgroup analysis revealed similar trends in patients with and without renal failure at liver transplant. Liver AR at 6 months was lower post-policy (6.3% vs. 18.3%, p =0.006) but was similar (10.5% vs. 13%, p =0.63) at 1 year. Kidney AR was unchanged post-policy at 6 months and 1 year. Creatinine at 1 year did not differ post-policy versus pre-policy (1.4 vs. 1.3 mg/dL, p =0.07) despite a higher proportion of deceased donors, higher Kidney Donor Profile Index, and longer kidney cold ischemia time post-policy ( p <0.05 for all). This 3-year follow-up after the 2017 UNOS policy revision demonstrated that the safety net implementation has resulted in improved liver outcomes for patients who underwent KALT with no increased AR of the liver or the kidney allografts.

RESUMO

The calf muscle pump is a major determinate of venous return in the legs but has not been studied as a risk factor for venous thromboembolism (VTE). A population-based cohort study of Olmsted County, Minnesota residents was performed using calf pump function (CPF) measurements from venous plethysmography studies from 1998 to 2015. Patients with a history of VTE were excluded. Nursing validated VTE outcomes from the Rochester Epidemiology Project were identified after the index study date, and patients with reduced CPF (rCPF) were compared with patients with normal CPF. A total of 1532 patients with recorded CPF (28% air and 72% strain gauge plethysmography) were included; 591 (38.5%) had normal CPF, 353 (23.0%) had unilateral rCPF, and 588 (38.3%) had bilateral rCPF. Any VTE occurred in 87 patients (5.7%) after a median follow-up of 11.7 years (range, 0-22.0 years). Comparing patients with bilateral reduced to bilateral normal CPF, the unadjusted hazard ratio (HR) for incident VTE was 2.0 (95% confidence interval [CI], 1.2-3.4) and after adjusting for age, BMI, and Charlson Comorbidity Index, the HR was 1.68 (95% CI, 0.98-2.89). The adjusted HR for ipsilateral deep vein thrombosis was evaluated in 3064 legs comparing legs with reduced to normal CPF and was 1.71 (95% CI, 1.03-2.84). Mortality was significantly higher in both the bilateral (P < .001) and unilateral (P < .001) rCPF groups compared with normal CPF. Our results demonstrate that CPF is a risk factor for VTE in an otherwise low-risk ambulatory population and might be a useful component in risk stratification models.

RESUMO

BACKGROUND: Clinical picture and outcome of incidental pulmonary embolism (iPE) compared to symptomatic pulmonary embolism (sPE) remain unclear. METHODS: Demographics, recurrent venous thromboembolism (VTE), mortality, major bleeding, and clinically relevant nonmajor bleeding (CRNMB) were compared between iPE and sPE patients who were followed prospectively at Mayo Thrombophilia Clinic (March 1, 2013 to August 1, 2020). RESULTS: Out of 3576 VTE patients, 1417 (39.6%) had PE: 562 (39.7%) iPE and 855 sPE. Patients with cancer were more likely to have iPE (400 iPE vs. 314 sPE) compared to those without cancer (162 iPE vs. 541 sPE). VTE recurrence rate (all per 100 person-years) was similar in all iPE and sPE patients (3.34 vs. 3.68, p = .50), with cancer (4.16 vs. 4.89, p = .370), and without cancer patients (0.89 vs. 2.80, p = .25). Higher mortality observed in all patients with iPE compared to sPE (46.45 vs. 23.47, p < .001) and with cancer (56.41 vs. 45.77, p = .03) became not significant after adjustment for age, antiplatelet therapy, metastases, and cancer location. Noncancer iPE patients had higher mortality (15.95 vs. 7.18, p = .006) even after adjustment (p = .05). The major bleeding rate was also higher in all patients iPE compared to sPE (7.10 vs. 3.68, p = .03), but not after adjustment (p = .974); higher major bleeding rate in noncancer patients (6.49 vs. 1.25, p = .007) remained significant after adjustment (.02). CRNMB rate was similar to iPE and sPE patients. CONCLUSION: iPE represents a more serious clinical condition compared to sPE as indicated by the higher mortality and major bleeding but these differences reflect underlying comorbidities rather than the seriousness of the embolic event.

RESUMO

BACKGROUND: Although presumed microvascular third nerve palsies (TNP) have been associated with vascular risk factors and/or stroke, these associations have not been explored in a population-based cohort. The purpose of this population-based case-control study was to determine whether these factors are associated with TNPs that had been classified as isolated microvascular ischemic events and determine future risk of mortality. METHODS: Participants were subjects >18 years old with new onset of isolated TNP attributed to presumed microvascular ischemia (n = 55) while residing in Olmsted County, Minnesota, from January 1, 1978 to December 31, 2014. Control subjects (n = 55) were randomly selected from the same population and matched for gender, age, and length of medical follow-up. We identified all cases of new-onset isolated presumed microvascular ischemic TNP using the Rochester Epidemiology Project, a record-linkage system of medical records for all patient-physician encounters in Olmsted County, Minnesota. All medical records of cases and controls were reviewed for potential risk factors, including diabetes mellitus, diabetic retinopathy, hypertension, hyperlipidemia, smoking, and symptomatic ischemic stroke. Multivariable and univariate logistic regression analyses were used to compare the prevalence of potential risk factors between microvascular ischemic cases and controls according to the number of subjects, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Kaplan-Meier curves were used to compare mortality between cases and controls. RESULTS: The annual incidence of microvascular ischemic TNP was 1.7 per 100,000. Univariate analysis demonstrated that hypertension ( P < 0.001; OR, 4.80; 95% CI, 2.11-11.58), diabetes mellitus ( P < 0.001; OR, 6.55; 95% CI, 2.72-17.32), diabetic retinopathy ( P = 0.014; OR, 13.50; 95% CI, 2.48-251.55), coronary artery disease ( P = 0.047; OR, 2.27; 95% CI, 1.02-5.18), and symptomatic ischemic stroke ( P = 0.039; OR, 3.56; 95% CI, 1.07-11.85) all occurred more frequently in patients with microvascular ischemic TNP than controls. In multivariate analysis, only hypertension (OR of 4.14, 95% CI, 1.61-10.65, P < 0.001) and diabetes (OR of 4.12, 95% CI, 1.43-11.92, P = 0.003) remained independently statistically significant. There was numerically higher mortality in microvascular cases than in controls, but it did not reach statistical significance. CONCLUSIONS: There are multiple cardiovascular diseases that are associated with isolated microvascular ischemic TNP, including hypertension, coronary artery disease, diabetes mellitus, diabetic retinopathy, and symptomatic ischemic stroke. Given that the main drivers of this association seem to be diabetes and hypertension, patients with microvascular ischemic TNP should be evaluated for these conditions.

RESUMO

Advances have dated the genetic testing initially offered to evaluate for hereditary breast and ovarian cancer risks. Previous research has demonstrated that many patients have not updated testing. This study reviewed the incidence of additional analysis after an uninformative BRCA1/2 result and offered updated testing with limited barriers to those who had not completed. After viewing an educational video and providing informed consent, eligible patients were mailed a saliva collection kit to complete an 84-gene hereditary cancer panel at no personal cost. A total of 704 patients had completed BRCA1/2 only testing between 2001 and 2020. Fifteen percent (N = 102) of the 671 patients with an uninformative BRCA1/2 result had already completed expanded testing. Most, 74 of 102 (73%), had been rereferred to medical genetics during a clinical visit related to cancer care. Those who had already completed additional testing were more likely to have a personal history of cancer (92% vs. 79%, p = 0.002) and live locally (p = 0.032). Invitation to complete updated testing through this study was sent to 372 people, and 116 (31%) consented to participate. For 142 of the 256 who did not proceed with testing through the study, proof of receipt of research information was available. In total, 22 pathogenic variants were reported in 21 of the 226 patients with updated testing from before and including our study: ATM (4), CHEK2 (4), LZTR1 (1), MUTYH (3), NBN (1), NF1 (1), NTHL1 (1), PALB2 (4), PMS2 (1), RAD50 (1), and SPINK1 (1). Many potential barriers of retesting were eliminated by removing personal costs or travel requirements. Still, only about 30% of patients agreed to participate, and a significant portion elected not to proceed. Future research could focus on the discovery of other factors that dissuade patients and what measures may better inform them on potential benefits.

RESUMO

BACKGROUND: We conducted a preliminary phase I, dose-escalating, safety, and tolerability trial in the population of patients with acute intracerebral hemorrhage (ICH) by using human allogeneic bone marrow-derived mesenchymal stem/stromal cells. METHODS: Eligibility criteria included nontraumatic supratentorial hematoma less than 60 mL and Glasgow Coma Scale score greater than 5. All patients were monitored in the neurosciences intensive care unit for safety and tolerability of mesenchymal stem/stromal cell infusion and adverse events. We also explored the use of cytokines as biomarkers to assess responsiveness to the cell therapy. We screened 140 patients, enrolling 9 who met eligibility criteria into three dose groups: 0.5 million cells/kg, 1 million cells/kg, and 2 million cells/kg. RESULTS: Intravenous administration of allogeneic bone marrow-derived mesenchymal stem/stromal cells to treat patients with acute ICH is feasible and safe. CONCLUSIONS: Future larger randomized, placebo-controlled ICH studies are necessary to validate this study and establish the effectiveness of this therapeutic approach in the treatment of patients with ICH.

RESUMO

OBJECTIVES: To explore trends in demographic characteristics of scleral lens (SL) practitioners and primary indications for SL fitting over 5 years. METHODS: An online survey similar to the 2015 Scleral Lenses in Current Ophthalmic Practice Evaluation (SCOPE) study was designed and administered from November 8, 2019, through March 31, 2020, to attendees at two international contact lens meetings, members of the Scleral Lens Education Society, and participants in the 2015 SCOPE study. Practitioners reporting at least five completed SL fits were included in the analysis. RESULTS: Of 922 respondents, 777 had fit at least five SLs: 63% from the United States (59 other countries were represented), findings similar to the 2015 survey, in which 799 respondents (72%) were US-based and 49 from other countries. Most practitioners were in community practice (76%) than academic practice (24%). In 2015, 64% were in community practice and 36% in academic practice. A median of 84% of SLs were fit for corneal irregularity, 10% for ocular surface disease, and 2% for uncomplicated refractive error. In comparison, the 2015 indications were 74%, 16%, and 10%, respectively. The median number of fits completed per practitioner was 100 (range, 5-10,000; mean [SD] 284 [717]; n=752). In 2015, the median was 36 (range, 5-3,600; mean [SD] 125 [299]; n=678). CONCLUSIONS: The number of experienced SL practitioners is increasing, as is international representation. Most practitioners practice in community rather than academic settings. SLs continue to be primarily prescribed for corneal irregularity and are rarely used solely for correction of refractive error.

RESUMO

PURPOSE: To report the prevalence, clinical characteristics, and natural history of orbital vascular anomalies diagnosed among children over a 50-year period. METHODS: The medical records of all patients <19 years diagnosed with any form of an orbital vascular anomaly (OVA) at Mayo Clinic, Rochester, Minnesota from January 1 1966, through December 31 2015, were retrospectively reviewed. RESULTS: A total of 109 children were diagnosed with OVA during the 50-year period, of which 24 were from Olmsted County, MN, yielding a birth prevalence of 1 in 4,305 live births. The median age at diagnosis for the 109 patients was 1.2 years (range, 0-17.9 years) and 67 (61.5%) were female. Common presenting symptoms included proptosis in 80 (73.4%) patients, abnormalities in skin color in 45 (41.3%) patients, and pain in 18 (16.5%) patients. There were 55 (50.5%) vascular malformations [50 (91%) low-flow lymphatic malformations, 3 (5.5%) high-flow arteriovenous malformations, and 2 (3.5%) low-flow venous malformations] and 54 (49.5%) vascular tumors [53 (98%) capillary hemangiomas and 1 (2%) kaposiform hemangioendothelioma]. During a mean follow-up of 5.95 years (range 0-27.7 years), amblyopia and/or strabismus were diagnosed in 46 (43.4%) patients. CONCLUSIONS: Capillary hemangiomas and low-flow lymphatic malformations comprise most of the orbital vascular anomalies in this cohort of children. Amblyopia and strabismus are common sequelae, highlighting the importance of early diagnosis and appropriate management.

RESUMO

This study identified the 100 most impactful global contributors to religion journals and mapped their respective disciplinary affiliations. To conduct this investigation, we performed a secondary data analysis of a Scopus-derived database featuring the world's leading scientists. The mean contributor published 51.93 papers, had an h-index of 13.57, and an hm-index 11.50. Most contributors were located in the USA with the most common disciplinary affiliations being religion, non-specialized (n = 22), sociology, non-specialized (n = 21), sociology of religion (n = 20), and theology (n = 11). The results reveal that religion discourse is populated by some of the leading scholars in the world. Leveraging their expertise can help advance the field's knowledge development.
