RESUMEN
BACKGROUND: The Multidimensional Task Ability Profile (MTAP) is a measure of self reported physical work capacity developed for injured workers with musculoskeletal disorders (MSDs) to determine readiness to return to work. OBJECTIVE: This study compared the concurrent validity of a new short form MTAP (MTAP-SF) comprised of 16 lifting and/or carrying items with the MTAP 55-item version. The hypothesis addressed is whether the validity of a version that imposes less respondent burden (MTAP-SF) would be comparable to the more burdensome instrument (MTAP-55). METHODS: MTAP scores were compared with demonstrated lift capacity in 1,252 healthy adults. Parallel regression analyses were conducted to examine the explanatory power of both MTAP versions. RESULTS: Age, gender, body mass and MTAP-SF explained 55% of the variance (pâ<â0.001) in demonstrated lift capacity, equivalent to MTAP-55. CONCLUSIONS: Self reported performance in physical work capacity tasks accounts for significant variance in lifting performance. MTAP-SF diminishes respondent burden while maintaining validity and may be useful for managing MSDs by enhancing understanding of the evaluee's psychophysical component in return-to-work rehabilitation planning.
RESUMEN
BACKGROUND: In December 2021, the U.S. Food and Drug Administration published a letter to clinical laboratory staff and healthcare providers detailing a risk of false Rapid Plasma Reagin (RPR) when using the Bio-Rad Laboratories BioPlex 2200 Syphilis Total & RPR kit in people who had received COVID-19 vaccination; Treponema pallidum particle agglutination assays did not appear to be impacted by this issue. We evaluated reactivity rates of syphilis screening with negative confirmatory testing at our institution by year and seasonality. METHODS: We performed a retrospective study of routine syphilis testing of whole blood (WB) collections at an academic hospital-based donor center in the eastern United States. All WB donations from 2011 to 2023 which demonstrated reactive syphilis screening (Beckman Coulter PK TP Microhemagglutination) with negative confirmatory testing (CAPTIA Syphilis (T. pallidum)-G) were evaluated. Reactivity rates by year and season of donation were compared using unpaired t-tests. RESULTS: A total of 109 WB donations from 86 unique donors who donated from 2011 to 2023 screened reactive for syphilis with negative confirmatory testing. The unconfirmed syphilis reactivity rate increased from 2018 to 2023 (mean: 0.360%) compared to 2011-2017 (mean: 0.071%, p < .05). An autumnal peak in unconfirmed reactives was observed. CONCLUSION: The unconfirmed syphilis reactivity rate among WB donors at our institution increased markedly since 2017 compared to the 7 years prior and doubled from 2020 to 2021. No testing assay changes explain these results. The autumnal peak in unconfirmed reactives suggests a possible environmental trigger such as viral infection or vaccination.
RESUMEN
OBJECTIVE: Evaluate outcomes of valve-sparing root replacement (VSRR) in patients with bicuspid aortopathy (BAV) versus other connective tissue disorder (CTD). METHODS: Single-center cohort study of consecutive patients undergoing VSRR via reimplantation from 2000-2023 with BAV or CTD. Operative outcomes, Kaplan-Meier survival estimates, and cumulative risk of reoperation and recurrent aortic insufficiency (AI) with the competing risk of death were assessed. RESULTS: Of 516 VSRR patients, 109 (51.9%) had BAV and 101 (48.1%) had CTD. BAV patients were older (46.9±10.4 vs 38.4±14 years, p<0.001) and more likely male ( 89.0% vs 56.4%, p<0.001) and hypertensive (66.1% vs 28.7%, p<0.001). Preoperative AI was similar (p=0.57) between groups (30.3% mild, 18.3% moderate, 11.1% severe). Most patients had no/trivial immediate postoperative residual AI (96.3% vs 93.1%). Operative mortality was zero; postoperative adverse events were minimal. Mean clinical follow-up was 5.2±4.4 years; ten-year survival was 95.6% vs 95.7% (p=0.70). Echocardiographic follow-up was 3.9±4.1 years; incidence of >2+ AI (9.7% vs 10.1%, p=1.0) was similar between groups, while incidence of moderate or greater aortic stenosis (AS) was higher with BAV (7.5% vs 0%, p=0.02). Reoperation was low in both groups (3.7% vs 5.9%, p=0.65). Competing risk analysis found no difference in reoperation hazard between BAV and CTD groups (hazard ratio 0.36, 95% confidence interval 0.07-1.81, p=0.21). CONCLUSIONS: BAV and CTD patients have excellent operative outcomes, no mortality, and minimal residual AI after VSRR. While the incidence of recurrent AI was similar, BAV patients are at risk for AS.
RESUMEN
Recent research suggests that infection with Onchocerca volvulus induces neurocognitive decline. This study sought to compare the cognitive outcomes of elderly persons based on onchocerciasis infection status and report the overall prevalence of dementia in the rural Ntui Health District in Cameroon. A community-based approach was used to recruit 103 participants aged ≥60 years. Dementia screening was done using the Community Screening Interview for Dementia (CSID) tool with a cut-off value of ≤29.5. O. volvulus infection was determined via microscopic examination of skin snips and serological testing of Ov16 antibodies using rapid diagnostic tests. Overall, the prevalence of dementia was 10.7%. Among the tested individuals, 17.9% (15/84) and 62.1% (41/66) were positive for O. volvulus and Ov16 antibodies, respectively. A multivariable linear regression model of CSID scores found a significant positive association with education level (8.654; 95% CI: 2.0870 to 15.222). However, having a positive skin snip for O. volvulus (-3.399; 95% CI: -6.805 to 0.007) and inhaling tobacco (-5.441; 95% CI: -9.137 to -1.744) tended to lower the CSID scores. Ongoing onchocerciasis transmission in the Ntui Health District may constitute a risk factor for dementia. Strengthening onchocerciasis elimination and adopting healthier lifestyles would contribute to dementia prevention among the elderly residing in endemic communities.
RESUMEN
BACKGROUND: We compared the outcomes of aortic root replacement by composite valve grafts (CVG) and valve-sparing root replacement (VSRR) operations, with an emphasis on postoperative conduction block and the need for permanent pacemaker implantation (PPM). METHODS: From 1997 to 2023, 1712 consecutive patients underwent ARR by VSRR (501 [29%]) or CVG (1211 [71%]) at a high-volume aortic center. RESULTS: Patients undergoing CVG were older (59 ± 14 vs 49 ± 14 years, P < .001), with more cardiovascular comorbidities. Compared with CVG, there were more women undergoing VSRR (17% vs. 13%, P = .042) and more patients with connective tissue disease (22% vs 7.3%, P < .001). Multivariable analysis found that the risk for PPM was higher after CVG compared with VSRR (6.5% vs 1.2%; odds ratio [OR], 2.83; 95% CI, 1.23-7.69; P = .024). Other variables associated with PPM include older age (OR, 1.03; 95% CI, 1.01-1.05; P = .006) preoperative renal impairment (OR, 2.69; 95% CI, 1.24-5.6; P = .010), previous operation (OR, 2.76; 95% CI, 1.29-5.62; P = .007), and bicuspid aortic valve (OR, 3.63; 95% CI, 2.13-6.33; P < .001). Among the CVG population, patients who are at increased risk are especially those with some degree of aortic stenosis (OR, 2.06; 95% CI, 1.18-3.61; P = .011). Patients who required PPM had no additive risk for long-term mortality (hazard ratio, 1.01; 95% CI, 0.47-2.17; P = .986); however, they were more likely to have reduced ejection fraction (29.3% vs 16%, P = .014). CONCLUSIONS: The incidence of PPM after ARR is low, but rates were higher after CVG compared with VSRR.
RESUMEN
BACKGROUND: Successful engraftment in hematopoietic stem cell transplantation necessitates the collection of an adequate dose of CD34+ cells. Thus, the precise estimation of CD34+ cells harvested via apheresis is critical. Current CD34+ cell yield prediction models have limited reproducibility. This study aims to develop a more reliable and universally applicable model by utilizing a large dataset, enhancing yield predictions, optimizing the collection process, and improving clinical outcomes. MATERIALS AND METHODS: A secondary analysis was conducted using the Center for International Blood and Marrow Transplant Research database, involving data from over 17 000 healthy donors who underwent filgrastim-mobilized hematopoietic progenitor cell apheresis. Linear regression, gradient boosting regressor, and logistic regression classification models were employed to predict CD34+ cell yield. RESULTS: Key predictors identified include pre-apheresis CD34+ cell count, weight, age, sex, and blood volume processed. The linear regression model achieved a coefficient of determination (R2) value of 0.66 and a correlation coefficient (r) of 0.81. The gradient boosting regressor model demonstrated marginally improved results with an R2 value of 0.67 and an r value of 0.82. The logistic regression classification model achieved a predictive accuracy of 96% at the 200 × 106 CD34+ cell count threshold. At thresholds of 400, 600, 800, and 1000 × 106 CD34+ cell count, the accuracies were 88%, 83%, 83%, and 88%, respectively. The model demonstrated a high area under the receiver operator curve scores ranging from 0.90 to 0.93. CONCLUSION: This study introduces advanced predictive models for estimating CD34+ cell yield, with the logistic regression classification model demonstrating remarkable accuracy and practical utility.

BACKGROUND/AIM: Diffuse large B-cell lymphoma of the central nervous system (CNS-DLBCL) is an aggressive B-cell lymphoma with clinical and molecular heterogeneity. Primary CNS-DLBCL (PCNSL) affects the brain, eyes, leptomeninges, or spinal cord without systemic involvement. Secondary CNS-DLBCL (SCNSL) manifests concurrently with systemic lymphoma or as an isolated CNS relapse with poor prognosis. MATERIALS AND METHODS: Next-generation sequencing (NGS) was used to identify genomic alterations in 32 PCNSL and 9 SCNSL cases. Single nucleotide variants and copy number variations in addition to the clinicopathologic data and proposed risk predictive values were compared to aid in diagnostic differentiation between the two types of lymphomas. RESULTS: The MCD genotype, characterized by mutations in MYD88 and CD79B, is the most common alteration in PCNSL and is associated with lower survival rates. The frequency of MYD88 mutation was significantly higher in PCNSL compared to SCNSL (75.0% vs. 33.3%; p=0.042). Recurrent copy number loss of 6p21 occurred in 56.1% of cases, more often in PCNSL (65.6%) than in SCNSL (22.2%) (p=0.028). Diagnostic positive predictive values (PPV) of MYD88 mutation and 6p21 loss for PCNSL were 89% and 91%, respectively. PPV of both alterations was 93% for the diagnosis of PCNSL. CONCLUSION: MYD88 mutation and 6p21 loss were significantly higher in PCNSL than in SCNSL, and novel risk prediction models based on these distinct genomic profiles can aid in the clinical differentiation of PCNSL and SCNSL.

BACKGROUND/AIM: Fibrin-associated large B-cell lymphoma (FA-LBCL) is a newly identified subtype of Epstein-Barr virus (EBV)-associated lymphoma. Arising within fibrinous material in confined spaces, FA-LBCL is associated with chronic inflammation. We herein report histopathologic features and molecular alterations of three cases of FA-LBCL to refine this new disease entity. MATERIALS AND METHODS: We performed immunohistochemical staining for CD3, CD20, CD10, Bcl-2, Bcl-6, MUM-1, CD10, and c-Myc and in situ hybridization for EBV-encoded RNA. Additionally, targeted DNA sequencing was conducted using commercially available gene panels. RESULTS: Three cases of FA-LBCL developed underlying lesions of retroperitoneal cyst, cardiac myxoma, and pancreatic cyst. Histopathologic features of these lesions were characterized by aggregates of atypical large cells in a background of fibrinous cellular debris. Atypical lymphoid cells were positive for CD20, Bcl-2, MUM-1, and EBV-in situ hybridization, negative for CD10, and variably positive for Bcl-6 and c-Myc. NGS analysis revealed the presence of pathogenic mutations in BRIP1, SOCS1, and KRAS. CONCLUSION: This is the first report of NGS analysis in FA-LBCL cases. It provides precise clinicopathological and molecular traits and allows its recognition as a new entity.

BACKGROUND: Both valve-sparing root replacement and composite valve graft (CVG) are acceptable options in aortic root replacement. We compare outcomes of these 2 approaches and durability of the aortic valve. METHODS: A consecutive 1635 patients without acute dissection underwent primary aortic root replacement from 1997 to 2022; 473 (29%) underwent valve-sparing root replacement, and 1162 (71%) received CVG. Propensity score matching was used to reduce baseline differences. RESULTS: The CVG group was older (59 ± 14 years vs 49 ± 14 years; P < .001) with more comorbidities, such as hypertension (88.4% vs 66.4%; P < .001), diabetes (7% vs 1.7%; P < .001), ischemic heart disease (5.1% vs 1.3%; P = .001), pulmonary disease (6.6% vs 1.3%; P < .001), renal impairment (8.6% vs 1.3%; P < .001), class III-IV heart failure (35% vs 9.2%; P < .001), bicuspid aortic valves (44.8% vs 24.1%; P < .001), and severe aortic insufficiency (50.2% vs 13.2%; P < .001). Operative mortality was 0.4% (0% in valve sparing); incidence of major postoperative complications was 2.9% (3.6% vs 1.1%; P = .009). Ten-year survival was 93.1% (91.2% vs 97.7%; hazard ratio [HR], 1.7; 95% CI, 0.9-3.3; P = .120). Mean follow-up was 65 ± 60 months; aortic valve reoperations were similar (5.8% vs 5.7%; HR, 0.8; 95% CI, 0.4-1.4; P = .401). Recurrent moderate-severe aortic insufficiency was less prevalent in CVG (6.1% vs 11.1%; HR, 0.14; 95% CI, 0.07-0.27; P < .001). Propensity score matching identified 225 pairs. There was no difference in 10-year survival or reoperations. Recurrent moderate-severe aortic insufficiency was higher with valve sparing. CONCLUSIONS: Both valve-sparing operations and CVG provide excellent early and late outcomes out to 10 years. Valve sparing is associated with a higher risk for development of aortic insufficiency but no difference in reoperations.

BACKGROUND: Biomechanical effects of transcatheter (TAVR) versus surgical (SAVR) aortic valve interventions on the distal aorta have not been studied. This study utilized global circumferential strain (GCS) to assess post-procedural biomechanics changes in the descending aorta after TAVR versus SAVR. METHODS: Patients undergoing TAVR or SAVR for aortic stenosis were included. Transesophageal (TEE) and transthoracic (TTE) echocardiography short-axis images of the aorta were used to image the descending aorta immediately before and after interventions. Image analysis was performed with two-dimensional speckle tracking echocardiography and dedicated software. Delta GCS was calculated as: post-procedural GCS-pre-procedural GCS. Percentage delta GCS was calculated as: (delta GCS/pre-procedural GCS) × 100. RESULTS: Eighty patients, 40 TAVR (median age 81 y/o, 40% female) and 40 SAVR (median 72 y/o, 30% female) were included. The post-procedure GCS was significantly higher than the pre-procedural GCS in the TAVR (median 10.7 [interquartile range IQR 4.5, 14.6] vs. 17.0 [IQR 6.1, 20.9], p = 0.009) but not in the SAVR group (4.4 [IQR 3.3, 5.3] vs. 4.7 [IQR 3.9, 5.6], p = 0.3). The delta GCS and the percentage delta GCS were both significantly higher in the TAVR versus SAVR group (2.8% [IQR 1.4, 6] vs. 0.15% [IQR - 0.6, 1.5], p < 0.001; and 28.8% [IQR 14.6%, 64.6%] vs. 4.4% [IQR - 10.6%, 5.6%], p = 0.006). Results were consistent after multivariable adjustment for key clinical and hemodynamic characteristics. CONCLUSIONS: After TAVR, there was a significantly larger increase in GCS in the distal aorta compared to SAVR. This may impact descending aortic remodeling and long-term risk of aortic events.

The external stenting of saphenous vein grafts (SVGs) during coronary artery bypass grafting (CABG) has been proven to reduce intimal hyperplasia (IH) in animal models, paving the way for human randomized controlled trials (RCTs) to be conducted. Herein, we performed a study-level meta-analysis to assess the impact of the Venous External SupporT (VEST) device, an external stent, on the outcomes of SVGs. A systematic search was conducted to identify all RCTs comparing VEST-stented to non-stented SVGs in patients undergoing CABG. The primary outcome was graft occlusion. The main secondary outcomes were repeat revascularization, SVG IH area, and intimal-medial thickness. Two RCTs totaling 407 patients were included. At a mean follow-up of 1.5 years, there was no difference in graft occlusion between groups (incidence rate ratio: 1.11; 95% confidence interval (CI): 0.80-1.53). The rate of repeat revascularization was also similar (odds ratio: 0.66; 95% CI: 0.27-1.64). The IH area (standardized mean difference (SMD): -0.45; 95% CI: -0.79 to -0.10) and intimal-medial thickness (SMD: -0.50; 95% CI: -0.90 to -0.10) were significantly reduced in the VEST group. Our findings show that significant reductions in the IH area and the intimal-medial thickness in VEST-stented SVGs do not currently translate into a lesser need for repeat revascularization or less graft occlusion events compared to non-stented SVGs at 1.5 years after CABG.
RESUMEN
OBJECTIVE: To review the available literature on the use of coronary artery bypass grafting (CABG) as a treatment option for anomalous origin of coronary artery in adults. METHODS: A systematic literature search was performed in March 2023 (including Ovid MEDLINE, Ovid Embase, and the Cochrane Library databases) to identify studies reporting the use of CABG in adult patients with anomalous origin of coronary artery. RESULTS: A total of 31 studies and 62 patients were included, 32 patients (52%) were women, and the mean age was 45.1±16.1 years. The most common coronary anomaly was the right coronary artery arising from the left coronary sinus in 26 patients (42%), followed by an anomalous left coronary artery from the pulmonary artery in 23 patients (37%). A total of 65 conduits were used in 61 patients, and 1 case report did not report conduit type. Reported grafts included saphenous vein (23 of 65 [35.4%]), left internal thoracic artery (15 of 65 [23.1%]), right internal thoracic artery (23 of 65 [35.4%]), and radial artery (2 of 65 [3.1%]); right gastroepiploic artery and basilic vein were used once (1.5%) each. Ligation of the native coronary artery was performed in 42 (67.7%) patients. Patient follow-up was available in 19 studies with a mean of 31.2 months. Only 1 operative mortality was reported. CONCLUSIONS: Based on the limited available data, CABG can be performed with good early results. Use of arterial conduits and ligation of the native coronary artery may improve long-term graft patency.

Saphenous vein grafts (SVGs) are the most frequently used conduits in coronary artery bypass grafting (CABG), but their higher rate of occlusion compared to arterial conduits remains a concern. Previous studies have shown that SVG failure is mainly driven by intimal hyperplasia, an adaptative response to higher pressures of the arterial circulation. The VESTTM device (Vascular Graft Solutions, Tel Aviv, Israel), an external support designed to mitigate intimal hyperplasia in SVGs, has been tested in few clinical trials (RCTs). Herein, we descriptively evaluated the randomized evidence on the VEST device.
RESUMEN
As a result of increasing adoption of imaging screening, the number of adult patients with a diagnosis of anomalous aortic origin of the coronary arteries (AAOCA) has grown in recent years. Existing guidelines provide a framework for management and treatment, but patients with AAOCA present with a wide range of anomalies and symptoms that make general recommendations of limited applicability. In particular, a large spectrum of interventions can be used for treatment, and there is no consensus on the optimal approach to be used. In this paper, a multidisciplinary group of clinical and interventional cardiologists and cardiac surgeons performed a systematic review and critical evaluation of the available evidence on the interventional treatment of AAOCA in adult patients. Using a structured Delphi process, the group agreed on expert recommendations that are intended to complement existing clinical practice guidelines.

Background: Spinal cord injury (SCI) is a rare but severe complication after open or endovascular repair of descending thoracic aneurysms (DTAs) or thoracoabdominal aortic aneurysms (TAAAs). This meta-analysis aims to provide a comprehensive assessment of SCI rates and factors associated with SCI. Methods: A systematic literature search was performed in September 2022 looking for studies on open and/or endovascular repair of DTA and/or TAAA published after 2018, to update the results of our previously published meta-analysis. The primary outcome was permanent SCI. Secondary outcomes were temporary SCI, 30-day and in-hospital mortality, follow-up mortality, postoperative stroke, and cerebrospinal fluid (CSF) drain-related complications. Data were pooled as proportions using inverse-variance weighting. Results: A total of 239 studies (71 new studies and 168 from our previous meta-analysis) and 61,962 patients were included. The overall pooled rate of permanent SCI was 3.3% [95% confidence interval (CI), 2.9-3.8%]. Open repair was associated with a permanent SCI rate of 4.0% (95% CI, 3.3-4.8%), and endovascular repair was associated with a permanent SCI rate of 2.9% (95% CI, 2.4-3.5%). Permanent SCI was 2.0% (95% CI, 1.2-3.3%) after DTA repair, and 4.7% (95% CI, 3.9-5.6%) after TAAA repair; permanent SCI rate was 3.8% (95% CI, 2.9-5.0%) for Crawford extent I, 13.4% (95% CI, 9.0-19.5%) for extent II, 7.1% (95% CI, 5.7-8.9%) for extent III, 2.3% (95% CI, 1.6-3.5%) for extent IV, and 6.7% (95% CI, 1.7-23.1%) for extent V TAAA aneurysms. The pooled rate of CSF drain related complications was 1.9% (95% CI, 0.8-4.7%) for severe, 0.4% (95% CI, 0.0-4.0%) for moderate, and 1.8% (95% CI, 0.6-5.6%) for minor complications. Conclusions: Permanent SCI occurs after both endovascular and open DTA or TAAA repairs. Open repairs and TAAA repairs have higher risk of SCI compared with endovascular or DTA repairs. In particular, extent II aneurysms present the highest overall risk of SCI.
RESUMEN
BACKGROUND: Postoperative atrial fibrillation (POAF) is the most frequent complication of cardiac surgery. Despite clinical and economic implications, ample variability in POAF assessment method and definition exist across studies. We performed a study-level meta-analysis to evaluate the influence of POAF assessment method and definition on its incidence and association with clinical outcomes. METHODS AND RESULTS: A systematic literature search was conducted to identify studies comparing the outcomes of patients with and without POAF after cardiac surgery that also reported POAF assessment method. The primary outcome was POAF incidence. The secondary outcomes were in-hospital mortality, stroke, intensive care unit length of stay, and postoperative length of stay. Fifty-nine studies totaling 197 774 patients were included. POAF cumulative incidence was 26% (range: 7.3%-53.1%). There were no differences in POAF incidence among assessment methods (27%, [range: 7.3%-53.1%] for continuous telemetry, 27% [range: 7.9%-50%] for telemetry plus daily ECG, and 19% [range: 7.8%-42.4%] for daily ECG only; P>0.05 for all comparisons). No differences in in-hospital mortality, stroke, intensive care unit length of stay, and postoperative length of stay were found between assessment methods. No differences in POAF incidence or any other outcomes were found between POAF definitions. Continuous telemetry and telemetry plus daily ECG were associated with higher POAF incidence compared with daily ECG in studies including only patients undergoing isolated coronary artery bypass grafting. CONCLUSIONS: POAF incidence after cardiac surgery remains high, and detection rates are variable among studies. POAF incidence and its association with adverse outcomes are not influenced by the assessment method and definition used, except in patients undergoing isolated coronary artery bypass grafting.
