Operation STICK Improves Vascular Access Outcomes in a Specialty Team: A Quasi-Experimental Study.

BACKGROUND: Education and training may improve outcomes within an experienced vascular access team. PURPOSE: The purpose of this study was to measure the impact of a standardized peripheral intravenous catheter insertion educational program (Operation STICK) on vascular access outcomes. METHODS: A quasi-experimental study design was used. Adult inpatients with difficult intravenous access (DIVA) requiring ultrasound-guided insertion by a vascular access specialty team were eligible. Data were collected before and 7 months after the educational training program. RESULTS: A total of 54 subjects were included (24 pre- and 30 post-implementation). Significant improvements were found for mean peripheral intravenous catheter dwell time (3.62 to 14.97 days, P < .001), completion of therapy (58.3% to 96.7%, P = .001), and first-stick success rate (79.2% to 100%, P = .013). Catheter-to-vein ratio significantly decreased (P = .007). CONCLUSIONS: Standardized education/training in vascular access focusing on best practices yields favorable outcomes for DIVA patients within an established specialty team.

Appropriate use of complementary and alternative medicine approaches in gynecologic cancers.

OPINION STATEMENT: Gynecologic cancer patients frequently desire alternative and/or complementary interventions or medicines to aid in relief of both cancer-related and treatment-related side effects. Furthermore, women also seek treatment to aid in superior outcomes and cure rates. Unfortunately, evidence suggests that the use of complementary and/or alternative medicine (CAM) is underreported or not discussed with physicians providing cancer care. In gynecologic cancer literature, there is a lack of scientific evidence either supporting or negating CAM. Because of the lack of information available, health care providers do not have good information regarding safety, efficacy, and dose of CAM. This leads to miscommunication or absence of communication between providers and patients. Because patients do use CAM to improve quality of life (QOL) during and after treatment, it would be educational for providers to know the specific QOL deficits among patients that require attention. Thus, with the ultimate goal of improving QOL for gynecologic cancer patients, providers should be pushed to investigate CAM and determine an honest support or rejection of these therapies.

The use of procedural kits may reduce unscheduled central line dressing changes: A matched pre-post intervention study.

Background: Unscheduled dressing changes for central venous lines (CVLs) have been shown to increase the risk of bloodstream infections. Objective: The objective of this study is to determine if the use of an innovative dressing change kit reduces the rate of unscheduled dressing changes. Methods: This pre-post interventional study took place at a large, academic, tertiary care center in metro Detroit, Michigan, the United States. We assessed the impact of the interventional dressing change procedure kit on the rate of unscheduled dressing changes for adult patients who underwent placement of a CVL inclusive of a central catheter, peripherally inserted central catheter, or hemodialysis catheter. Data was collected for the pre-intervention cohort through electronic health records (EHRs), while data for the post-intervention cohort were collected by direct observation by trained research staff in combination with EHR data. The primary outcome was the rate of unscheduled dressing changes. Secondary outcomes included rate of unscheduled dressing changes based on admission floor type, etiology of unscheduled dressing changes, and central line-associated bloodstream infections (CLABSIs). Results: The study included a convenience sample of 1548 CVLs placed between May 2018 and June 2022 with a matched analysis including 488 catheters in each of the pre- and post-intervention groups. The results showed that the unadjusted rate of unscheduled dressing evaluations was significantly reduced from the pre-intervention group (0.21 per day) to the post-intervention group (0.13 per day) (p < .001). The adjusted rate ratio demonstrated the same trend at 1.00 pre- and 0.60 post-intervention (p < .001). Stratifying the analysis based on the highest level of care showed that the intervention was effective in reducing the unadjusted rate of unscheduled dressing evaluations for both the advanced and regular medical floor subgroups pre- to post-intervention; the advanced subgroup had an reduction from 0.22 to 0.15 per day (p = .001), while the regular medical floor subgroup had a reduction from 0.21 to 0.09 per day (p < .001). CLABSIs were similar in both groups (0.6% vs 0.8%; p = 1.00) in pre- and post-intervention groups, respectively. Discussion: Procedural kits for central line dressing changes are effective in reducing unscheduled dressing changes and may have a role in reducing CLABSI. Further studies assessing the impact of dressing change kits on cost, procedural compliance, and the precise impact on CLABSI are needed.

Antiandrogen Flutamide-Induced Restoration of miR-449 Expression Mitigates Functional Biomarkers Associated with Ovarian Cancer Risk.

Background: The involvement of the androgen and androgen receptor (AR) pathway in the development of epithelial ovarian cancer is increasingly recognized. However, the specific mechanisms by which anti-androgen agents, such as flutamide, may prevent ovarian cancer and their efficacy remain unknown. We examined the effects of flutamide on the miRNA expression profile found in women at high risk (HR) for ovarian cancer. Methods: Ovarian and tubal tissues, free from ovarian, tubal, peritoneal cancers, and serous tubal intraepithelial carcinoma (STIC), were collected from untreated and flutamide-treated HR women. Low-risk (LR) women served as controls. Transcriptomic miRNA sequencing was performed on these 3 sample cohorts. The miRNAs that showed the most notable differential expression were subjected to functional assays in primary ovarian epithelial cells and ovarian cancer cells. Results: Flutamide treatment demonstrated a normalization effect on diminished miRNA levels in HR tissues compared to LR tissues. Particularly, the miR-449 family was significantly upregulated in HR ovarian tissues following flutamide treatment, reaching levels comparable to those in LR tissues. MiR-449a and miR-449b-5p, members of the miR-449 family, were computationally predicted to target the mRNAs of AR and colony-stimulating factor 1 receptor (CSF1R, also known as c-fms), both of which are known contributors to ovarian cancer progression, with emerging evidence also supporting their roles in ovarian cancer initiation. These findings were experimentally validated in primary ovarian epithelial cells and ovarian cancer cell lines (SKOV3 and Hey): flutamide treatment resulted in elevated levels of miR-449a and miR-449b-5p, and introducing mimics of these miRNAs reduced the mRNA and protein levels of CSF1R and AR. Furthermore, introducing miR-449a and miR-449b-5p mimics showed inhibitory effects on the migration and proliferation of ovarian cancer cells. Conclusion: Flutamide treatment restored the reduced expression of miR-449a and miR-449b-5p in HR tissues, thereby decreasing the expression of CSF1R and AR, functional biomarkers associated with an increased risk of ovarian cancer. In addition to the known direct binding of flutamide to the AR, we found that flutamide also suppresses AR expression via miR-449a and miR-449b-5p upregulation, revealing a novel dual-inhibitory mechanism on the AR pathway. Taken together, our study highlights mechanisms supporting the chemopreventive potential of flutamide in ovarian cancer, particularly in HR patients with reduced miR-449 expression.

Multiple Myeloma in Adolescent and Young Adults: An ASCO CancerLinQ and SEER Analysis.

BACKGROUND: Multiple myeloma (MM) is exceedingly rare in adolescents and young adults (AYAs) < 45 years of age. METHODS: Real-world data from ASCO's CancerLinQ DiscoveryⓇ (CLQD) MM dataset and SEER were utilized to characterize demographics and outcomes of AYA MM patients in the United States in the modern treatment era. Frequencies of SPMs, VTEs, and infections were assessed, as were OS and cause of death. RESULTS: A total of 1946 AYA MM patients from SEER and 1334 from CancerLinQ were included. In terms of SPMs, AYAs were more likely to develop ALL (RR 2.6, P = .003) and AML (RR 1.7, P = .034), and less likely to develop nonmelanoma skin cancer (RR 0.2, P = .001) and prostate cancer (RR 0.1, P = .013) than MM patients ≥ 45. AYAs were at lower risk of VTE (RR 0.75, P = .002) and slightly higher risk of infections (RR 1.11, P = .002). Median OS among AYA MM patients was significantly longer than MM patients ≥ 45 in both datasets. In the SEER cohort, female sex (HR 0.74, P = .003), non-Hispanic ethnicity (HR 0.73, P = .005), and annual household income ≥ $65,000 per year (HR 0.67, P = .001) were associated with lower hazards of mortality. In the CLQD cohort, OS was significantly influenced by female sex (HR 0.6, P = .048). Race did not have a statistically significant impact OS in either cohort. Most AYAs died of MM (68.3%), other primary malignancy (7.5%, mostly leukemia), and cardiovascular events (5.2%). Infections accounted for 3.2% of deaths. CONCLUSION: This analysis highlights some unique characteristics of AYA MM patients in the United States in the modern era.

Bridging the Gap in Traditional PIVC Placement: An Evaluation of Operation STICK Vascular Access Outcomes.

Objective: Education and training is core to improving peripheral intravenous access outcomes. This study aimed to show that a vascular access training program (Operation STICK) in the emergency department (ED) improves the outcomes of traditionally placed peripheral intravenous catheters (PIVC). Methods: This was a pre-post quasi-experimental study of traditionally placed PIVCs at a large ED in southeastern Michigan, United States. A control group (non-OSTICK) was compared to an experimental group (OSTICK) using a 3:1 propensity score matched analysis. Groups were comprised of ED patients with traditional PIVC placements in two separate six-month periods: non-OSTICK PIVCs from April to September 2021 and OSTICK PIVCs (placed by an OSTICK graduate) from October 2022 to March 2023. The primary outcome was PIVC functionality. The secondary outcome was adherence to best practices. Results: A total of 6512 PIVCs were included in the study; 4884 (75.0%) were in the non-OSTICK group, while 1628 (25.0%) were in the OSTICK group. 68.1% of OSTICK PIVCs and 59.7% of non-OSTICK PIVCs were placed by ED technicians (p < 0.001). 91.3% of OSTICK PIVCs were placed on the first attempt, and 98.5% were placed within two attempts. A subgroup analysis of admitted patients (2540 PIVCs; 553 (21.8%) OSTICK-trained and 1987 (78.2%) non-OSTICK-trained) revealed 87.6% of OSTICK PIVCs and 80.3% of non-OSTICK PIVCs were 20 gauge (p < 0.001). The median proportion of dwell time to hospital length of stay was 94% for OSTICK PIVCs, compared to 88% for non-OSTICK PIVCs (p < 0.001). Conclusion: This study underscores the value of education and training in enhancing vascular access outcomes. Implementing Operation STICK, a comprehensive vascular access training program, at a large ED has led to high first-stick success, adherence to best practice recommendations for site and device selection, and improved PIVC functionality for traditionally placed catheters.

The emerging importance and evolving understanding of clonal hematopoiesis in multiple myeloma.

Multiple myeloma (MM) is the second most common hematologic malignancy diagnosed in the United States. With a growing arsenal of novel therapies, patients are living longer and hence are at increased risk of secondary cancers such as myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). While MDS-associated cytogenetic abnormalities have been described in patients with a diagnosis of for decades, clonal hematopoiesis (CH) has been described only recently. CH has been shown to correlate with inferior survival in MM due to increased risk of disease progression in patients who are treated with high-dose melphalan without lenalidomide maintenance. When involving specific high-risk genes, multiple genes, or when present at high variant allelic frequencies, CH could also potentially elevate the risk of secondary MDS and/or AML, cardiovascular events, and venous thromboembolic events. Despite growing knowledge about CH in patients with MM, many questions remain unanswered. Further studies are needed to better understand the prognostic and therapeutic significance of CH in MM and its precursor conditions, as well as the effect of specific treatments on long-term outcome.

Approach to Pancytopenia in a Deployed Service Member.

Background: Pancytopenia is a result of increased destruction or decreased production of bone marrow cells and has a broad differential. Pernicious anemia commonly presents as a macrocytic anemia and is typically autoimmune in nature and the result of vitamin B12 deficiency. Pancytopenia is a rare presentation of this disorder especially in the setting of hemolysis. Testing in the deployed setting may be limited and/or challenging. Case Presentation: A 24-year-old female patient with a history of Hashimoto thyroiditis presented during an overseas deployment with a witnessed syncopal episode and was found to be pancytopenic with a mild transaminitis and laboratory tests demonstrating hemolysis. Though initially she was hypotensive, tachycardic, and febrile, her vitals improved after multiple transfusions, but she had persistent cytopenia with transfusion dependence, concerning for aplastic anemia or acute leukemia. Conclusions: Testing for B12 deficiency is crucial in symptomatic, patients with pancytopenic to either diagnose or exclude pernicious anemia and conserve resources by preventing costly workup and transfer/escalation of medical care, especially in the deployed setting. A predeployment screening in those with history of autoimmune disorders may be warranted.

Intraoperative Transesophageal Echocardiography in Management of Acute Type I Aortic Dissection With Malperfusion: A Case Report.

Acute type I aortic dissection is a life-threatening emergency with potentially devastating complications, including end-organ malperfusion. Early detection of malperfusion with intraoperative imaging allows for efficient transition to appropriate interventions. We present a case of a 65-year-old male with acute type I aortic dissection who underwent emergent surgical repair of the aortic root and hemiarch followed by acutely worsening distal malperfusion. The use of intraoperative transesophageal echocardiography played a critical role in visualizing diversion of flow to the false lumen, prompting urgent vascular surgery consultation and life-saving thoracic endovascular aortic repair.

Impact of Alcohol Consumption on Snoring and Sleep Apnea: A Systematic Review and Meta-analysis.

OBJECTIVE: To systematically review the international literature for studies evaluating the effect of alcohol consumption on the occurrence and severity of snoring and obstructive sleep apnea and to use the available data to perform a meta-analysis. DATA SOURCES: MEDLINE, Embase, The Cochrane Library, CINAHL/EBASCO, and Scopus. REVIEW METHODS: The protocol was registered in PROSPERO in March 2018. Following PRISMA guidelines, 2 independent researchers conducted a search from their inception through July 2018. Polysomnography (PSG) data were collected for sleep stages, apnea-hypopnea index (AHI), respiratory disturbance index, and/or lowest oxygen saturation (LSAT). Data concerning the frequency and severity of snoring intensity and sleep architecture were also collected. Only studies with PSG data were evaluated, with exclusion of studies with home sleep testing data. A multivariate regression and pooled analysis with forest plot was performed. RESULTS: A total of 1266 manuscripts were screened, and 13 manuscripts with 279 patients met inclusion criteria. Pooled analysis of AHI for control versus alcohol consumption revealed a mean difference (MD) of 3.98 events per hour (95% CI, 3.27 to 4.68; P < .001). Pooled analysis of LSAT for control versus alcohol consumption revealed an MD of -2.72% (95% CI, -3.69 to -1.76; Z score, 5.53; P < .00001). CONCLUSION: Alcohol consumption is associated with worsening severity of snoring, altered sleep architecture, AHI, as well as lowest oxygen saturation among patients susceptible to snoring and obstructive sleep apnea.
