AbstractBackgroundTrauma remains the leading cause of pediatric mortality in the United States. Although use of massive transfusion protocols (MTPs) in this population is widespread, optimal pediatric resuscitation is not well established. We sought to assess contemporary pediatric MTP practice in the United States.Study Design and MethodsA web‐based survey was designed by the Association for the Advancement of Blood & Biotherapies (AABB) Pediatric Transfusion Medicine Subsection and distributed to select American College of Surgeons (ACS) Level I Verified pediatric trauma centers. The survey assessed current MTP policy, implementation, and recent changes in practice.ResultsResponse rate was 55% (22/40). Almost half of the respondents were from the South. The median RBC:plasma ratio was 1 (interquartile range 1–1.5). Protocolized fibrinogen supplementation was common while integration of antifibrinolytic therapy into MTPs was infrequent. Viscoelastic testing (VET) was available at most sites, 71% (15/21, one site did not respond), and was generally utilized on an ad‐hoc basis. Roughly, a third of sites had changed their MTP in the past 3 years due to blood supply issues, and about a third reported having group O Whole Blood on‐site.ConclusionMTP practice is similar throughout the United States. Though fibrinogen supplementation is common—other emerging interventions such as antifibrinolytic therapy or utilization of routine viscoelastic testing—are not widespread. Pediatric transfusion medicine experts must continue to follow practice change, as contemporary large trials begin to characterize new supportive modalities to optimize resuscitation in pediatric trauma patients.

Background and Objectives: Proteomics encompasses the exploration of protein composition, regulation, function, and pathways. Its influence spans diverse clinical fields and holds promise in addressing various women’s health conditions, including cancers, osteoporosis, and cardiovascular disorders. However, no comprehensive summary of proteomics and menopausal health exists. Our objective was to summarize proteomic profiles associated with diseases and disorders in peri- and postmenopausal women. Materials and Methods: We conducted a comprehensive search of databases including PubMed, Google Scholar, the Cochrane database, Elsevier, and ScienceDirect until 2022. A total of 253 studies were identified, and 41 studies met the inclusion criteria to identify data of interest. These included the study design, disease, and proteomics/proteins of significance, as described by the authors. Results: The 41 studies covered diverse areas, including bone disorders (10 studies), cardiovascular diseases (5 studies), oncological malignancies (10 studies), and various conditions, such as obesity, nonalcoholic liver disease, the effects of hormone replacement therapy, and neurological diseases (16 studies). The results of our study indicate that proteomic profiles correlate with heart disease in peri- and postmenopausal women, with distinct sex differences. Furthermore, proteomic profiles significantly differ between women with and without osteoporosis. Additionally, patients with breast, ovarian, and endometrial cancer exhibit notable variations in proteomic profiles compared to those without these conditions. Conclusions: Proteomics has the potential to enhance risk assessment and disease monitoring in peri- and postmenopausal women. By analyzing unique protein profiles, clinicians can identify individuals with heightened susceptibility to specific diseases or those already affected by established conditions. This review suggests that there is sufficient preliminary data related to proteomics in peri- and postmenopausal women for early identification of cardiovascular disease, osteoporosis, and cancers, disease monitoring, and tailoring individualized therapies. Rigorous validation studies involving large populations are essential before drawing definitive conclusions regarding the clinical applicability of proteomic findings.

Context.— Gastrointestinal manifestations of Kaposi sarcoma are rare but may cause morbidity. Lower gastrointestinal involvement is particularly rare, and lesions may resemble conventional bowel polyps. Objective.— To study 15 patients who presented with lower gastrointestinal tract Kaposi sarcoma with polypoid architecture. Design.— The surgical pathology files of the departments of pathology at multiple institutions were searched for cases of Kaposi sarcoma forming polyps in the lower gastrointestinal tract (jejunum, colon, rectum); 15 cases with such features were identified. Clinicopathologic information was extracted from the medical record and documented by reviewing individual hematoxylin-eosin–stained slides. Results.— The patients were 13 men and 2 women aged 26–80 years (median = 44 years). Gastrointestinal tract involvement was multifocal in 11 cases and unifocal in 4. The tumors involved the rectum, rectosigmoid junction, cecum, ascending colon, transverse colon, and descending colon and presented as polypoid lesions measuring 0.2–2.1 cm. Six patients had upper gastrointestinal tract involvement in addition to lower gastrointestinal lesions. Histologically, the tumors were characterized in 6 cases by a dense spindle cell proliferation in the lamina propria; however, the remaining cases showed only a subtle fascicular spindle cell proliferation in the lamina propria that did not form an expansile mass. Conclusions.— Biopsies of gastrointestinal polyps showing absence of the common features of hyperplastic or adenomatous polyps, particularly in immunocompromised patients, should be carefully examined for the presence of a stromal spindle cell proliferation. Use of immunohistochemical stains, particularly human herpesvirus-8, can help in establishing the correct diagnosis.

AbstractBackgroundThe psychological and cardiovascular health impacts on family members of patients who have been diagnosed with cancer have not been well characterized. The purpose of this study is to determine whether a family member’s cancer diagnosis influences the risk of psychological illness and cardiovascular disease in first‐degree relatives and spouses of patients affected by cancer.MethodsThis retrospective cohort analysis evaluated the risk of psychological illness and cardiovascular disease in first‐degree relatives and spouses of patients diagnosed with a genitourinary cancer between 1990 and 2015 compared to relatives of those not diagnosed with a genitourinary cancer. The Utah Population Database was used and familial linkage was determined. Follow‐up included 1‐, 3‐, and 5‐year intervals. Patients residing outside of Utah and first‐degree relatives and spouses with psychological or cardiovascular disease diagnosed before a family member’s cancer diagnosis were excluded.ResultsA total of 49,284 patients with a genitourinary cancer were identified with 77,938 first‐degree relatives and spouses. A matched control group included 246,775 patients with 81,022 first‐degree relatives and spouses. Via Cox proportional hazards models, a 10% increased risk of developing a psychological illness (hazard ratio [HR], 1.10; 95% CI, 1.00–1.20) and a 28% increased risk of developing cardiovascular disease (HR, 1.28; 95% CI, 1.17–1.41) at 1 year after a family member’s cancer diagnosis were found.ConclusionsThis study provides population‐level evidence to support the hypothesis that cancer diagnoses will lead to adverse health outcomes for family members of patients with cancer. Increased clinical attention and support are needed to reduce the harm to families caused by cancer.

Background. Identification and treatment of latent tuberculosis infection (LTBI) mitigate the risk of tuberculosis (TB) reactivation after transplantation. TB reactivation is higher in those with indeterminate QuantiFERON (QFT) than those with negative results. Management of indeterminate QFT results in the pretransplant period remains unclear. Methods. We conducted a retrospective study of solid organ transplant (SOT) recipients, 18 y and older, who were screened with QFT assay pretransplantation at Mayo Clinic between January 2010 and June 2023. We examined the frequency of indeterminate QFT results, results of repeat LTBI screening, treatment decisions, and rate of posttransplant TB infection. Results. Of 13 008 patients screened for LTBI before SOT, 736 (6%) patients had indeterminate QFT results. Among these, 247 (34%) underwent a second LTBI screening test, and 39 (5%) received LTBI treatment. Among 247 patients with a repeat LTBI screening test, 185 (75%), 48 (19%), and 14 (6%) were tested by QFT, T-SPOT.TB, or TST, respectively. The repeat QFT remained indeterminate in 160 (86%) patients, whereas all T-SPOT.TB results were negative. Posttransplant TB infection occurred in 2 (0.3%) patients; neither had a second TB screening test pretransplant nor received LTBI treatment. Conclusions. In SOT recipients with indeterminate QFT results at pretransplant evaluation, opting for T-SPOT.TB as a second test may be preferable over repeat QFT. TB infection after transplantation in patients with a pretransplant indeterminate QFT result was rare. Patient management and LTBI treatment in those with indeterminate QFT pretransplant should account for epidemiological risk factors, and shared decision-making is recommended.

Abstract Background Cyclin-dependent kinases (CDK) 4/6 inhibitors have significantly improved outcomes for patients with ER+/HER2− breast cancer. Nevertheless, they differ from each other in terms of chemical, biological, and pharmacological features, as well as toxicity profiles. We aim to determine whether QTc prolongation is caused by CDK4/6i in general or if it is associated with ribociclib only. Methods We systematically searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs) comparing the prevalence of QTc prolongation as an adverse event in HR+ breast cancer patients treated with CDK4/6i vs those without CDK4/6i. We pooled relative risk (RR) and mean difference (MD) with 95% confidence interval (CI) for the binary endpoint of QT prolongation. Results We included 14 RCTs comprising 16 196 patients, of whom 8576 underwent therapy with CDK4/6i. An increased risk of QTc prolongation was associated with the use of CDK4/6i (RR = 2.35, 95% CI = 1.67 to 3.29, P < .001; I2 = 44%). Subgroup analyses revealed a significant increase in the QTc interval for the ribociclib and palbociclib cohorts. The ribociclib subgroup showed a relative risk of 3.12 (95% CI = 2.09 to 4.65, P < .001; I2 = 12%), whereas the palbociclib subgroup had a relative risk of 1.51 (95% CI = 1.05 to 2.15, P = .025; I2 = 0%). Conclusion Palbociclib was associated with QTc prolongation; however, the relative risk for any grade QTc was quantitively twice with ribociclib. Furthermore, grade 3 QTc prolongations were observed exclusively with ribociclib. These results are important for guiding clinical decision-making and provide reassurance regarding the overall safety profile of this drug class.

Interstitial lung disease (ILD) is a frequent manifestation of rheumatoid arthritis (RA) that is associated with high mortality. RA‐ILD may initially be asymptomatic, and lung function may be markedly impaired by the time it is diagnosed. The course of RA‐ILD is highly variable, with some patients experiencing no discernable progression or a slow decline, whereas others experience more rapid deterioration. Some patients develop progressive pulmonary fibrosis, which is associated with high mortality. Although risk factors for the progression of RA‐ILD have been identified, including older age, worse lung function, and a usual interstitial pneumonia pattern on high‐resolution computed tomography, it is not possible to predict the course of RA‐ILD in an individual patient. The association between RA disease activity and progression of RA‐ILD remains unclear. Regular monitoring is important to enable the prompt identification of progression and early intervention to preserve lung function. The management of RA‐ILD requires a multidisciplinary and individualized approach, taking account of the severity and progression of articular and lung disease, risk factors for the progression of RA‐ILD, and the patient's preferences, and may include immunosuppression, antifibrotic therapy, and supportive care.

OBJECTIVE Depression and anxiety are associated with poor outcomes following spine surgery. However, the influence of these conditions on achieving a minimal clinically important difference (MCID) following lumbar spine surgery, as well as the potential compounding effects of comorbid depression and anxiety, is not well understood. This study explores the impact of comorbid depression and anxiety on long-term clinical outcomes following surgical treatment for degenerative lumbar spondylolisthesis. METHODS This study was a retrospective analysis of the multicenter, prospectively collected Quality Outcomes Database (QOD). Patients with surgically treated grade 1 lumbar spondylolisthesis from 12 centers were included. Preoperative baseline characteristics and comorbidities were recorded, including self-reported depression and/or anxiety. Pre- and postoperative patient-reported outcomes (PROs) were recorded: the numeric rating scale (NRS) score for back pain (NRS-BP), NRS score for leg pain (NRS-LP), Oswestry Disability Index (ODI), and EQ-5D. Patients were grouped into 3 cohorts: no self-reported depression or anxiety (non-SRD/A), self-reported depression or anxiety (SRD/A), or presence of both comorbidities (SRD+A). Changes in PROs over time, satisfaction rates, and rates of MCID were compared. A multivariable regression analysis was performed to establish independent associations. RESULTS Of the 608 patients, there were 452 (74.3%) with non-SRD/A, 81 (13.3%) with SRD/A, and 75 (12.3%) with SRD+A. Overall, 91.8% and 80.4% of patients had ≥ 24 and ≥ 60 months of follow-up, respectively. Baseline PROs were universally inferior for the SRD+A cohort. However, at 60-month follow-up, changes in all PROs were greatest for the SRD+A cohort, resulting in nonsignificant differences in absolute NRS-BP, NRS-LP, ODI, and EQ-5D across the 3 groups. MCID was achieved for the SRD+A cohort at similar rates to the non-SRD/A cohort. All groups achieved > 80% satisfaction rates with surgery without significant differences across the cohorts (p = 0.79). On multivariable regression, comorbid depression and anxiety were associated with worse baseline PROs, but they had no impact on 60-month PROs or 60-month achievement of MCIDs. CONCLUSIONS Despite lower baseline PROs, patients with comorbid depression and anxiety achieved comparable rates of MCID and satisfaction after surgery for lumbar spondylolisthesis to those without either condition. This quality-of-life benefit was durable at 5-year follow-up. These data suggest that patients with self-reported comorbid depression and anxiety should not be excluded from consideration of surgical intervention and often substantially benefit from surgery.
