Selective Genicular Artery Embolization in the Management of Osteoarthritic Knee Pain-A Narrative Review.

Many people with pain from osteoarthritis (OA) of the knee are either not ready for surgery or may never be surgical candidates. Genicular artery embolization (GAE) is a new proposed management for those with pain despite maximum medical management. It has historically been used to manage recurrent spontaneous haemarthrosis following total knee replacement, but newer studies are showing a positive effect in managing pre-arthroplasty knee OA. The goal of this review is to summarise current and relevant literature from searches of computerised databases and relevant journals, and analyse their results. Studies included show that GAE has promising outcomes in managing mild to moderate OA knee pain in those who have exhausted at least 3 months of conservative therapy. Most studies show improvements in VAS pain and PROM scores (including KOOS, and/or WOMAC). Minimal adverse effects have been associated in up to two years of follow up, the majority of which are self-resolving. The article précises a concise general procedural technique for performing GAE, as well as comparing and contrasting different embolic agents that may be utilised. GAE shows promising outcomes in management of mild to moderate OA knee pain. In the future, there will need to be higher volume studies to determine effectiveness, suitable candidates, and other potential adverse effects.

Evaluating the Impact of Pulmonary Arterial Hypertension Therapies on Pericardial Effusion and Patient Survival.

To evaluate the impact of Pulmonary Arterial Hypertension (PAH) therapies on the incidence of pericardial effusion and its prognostic implications for patient survival. This retrospective cohort study included 60 patients diagnosed with PAH at a high-volume tertiary care center, treated with intravenous or subcutaneous prostanoids. Data were collected from 2015 to 2019, including echocardiographic assessments, right heart catheterization, World Health Organization functional class evaluations, six-minute walk distance tests, and biomarkers such as brain natriuretic peptide and N-terminal prohormone of brain natriuretic peptide. Follow-up was conducted at least 90 days post-treatment initiation. Pericardial effusion was observed in 31.7% of patients before therapy. Patients with moderate to large effusions had a significantly higher mortality risk (HR = 1.92; 95% CI 1.1-44.78; p =0.0044), while small effusions appeared protective (HR = 0.27; 95% CI 0.15-0.48; p =0.006). Survival rates declined from 89% at one year to 71% at three years post-therapy, with effusion presence correlating with more severe PAH manifestations. Initial pericardial effusion severity is a critical predictor of mortality in PAH patients. Early assessment and stratified management of pericardial effusion are essential for optimizing therapeutic outcomes in PAH management. Future research should explore targeted interventions for managing pericardial effusion to improve patient prognosis.

Analysis of Clinical Competencies among Staff Nurses Regarding Pressure Ulcer Management

Pressure Ulcer (PU) development continues to be a significant issue for at-risk patients. These ulcers are classified as "never events" since they are preventable and should "never" occur. Managing pressure ulcers is considered a sign of quality nursing care, and nurses must possess comprehensive information about the latest evidence-based practices about pressure ulcers. To analyze the clinical competencies regarding pressure ulcer management among staff nurses. A self-administered questionnaire was used in a descriptive, cross-sectional study to analyze the clinical competencies of 74 nurses from Liaquat University Hospital about pressure. The data was analyzed by descriptive statistical methods (frequency and percentage). The total population consisted of 74 staff nurses. Female respondents were 66.2%, and males were 33.8%. Most participants were within the 26-35 age range (43.2%). Work areas encompassed diverse specialties, with significant representation in ICU (16.2%) and medicine (17.6%), among others. Experience levels were also varied, with substantial proportions having 1-5 years (39.2%) and 5- 10 years (43.2%) of experience. The study revealed the nurses' capabilities in this area, revealing their strengths and areas needing improvement. By addressing these insights through focused educational programs and training, the quality of patient care and outcomes in pressure ulcer management could be improved. Moreover, initiatives aimed at fostering gender diversity and supporting professional growth, including pursuing advanced degrees, may strengthen the competency of nursing staff in this vital aspect of patient care.

#2931 Advancing personalized extracorporeal therapies for albumin bound toxins through serum albumin binding function

Abstract Background and Aims Liver failure poses a significant clinical challenge with compromised functionality of the liver and accumulation of toxic metabolites. The lack of bedside-compatible methods to evaluate treatment response during therapy underscores the urgent need for refined diagnostic tools. Albumin, the principal transport protein, reflecting the elevated toxin and metabolite levels in liver failure, assumes a critical role in assessing the severity of hepatic dysfunction. This research introduces a novel method centered on a dansylsarcosine-based kinetic modeling of serum albumin binding, aiming to improve therapeutic decision-making in hepatic failure. This biomarker is designed to offer critical insights into albumin's dynamic interactions, essential for assessing liver function and effectiveness of therapeutic interventions. The study aims to supplement existing diagnostic methods, providing a more comprehensive evaluation of irreversible damages of albumin in liver failure and guiding more effective treatment strategies. Method In this study, we employed a novel method for measuring binding affinity at varying levels of dansylsarcosine, aiming to describe the kinetic properties of the Sudlow II binding site. The binding behavior of albumin under various concentrations of dansylsarcosine was characterized using a modified Michaelis-Menten kinetic model. To enhance accuracy, a formula correction was employed for both intrinsic absorbance and the influence of dansylsarcosine. The method facilitates kinetic modeling, exploring the behavior of the binding site under diverse ligand concentrations. Emerging from this are two key players: Bmax and Kd. Bmax quantifies the maximum capacity of binding sites available for occupation by dansylsarcosine. Kd signifies the concentration of dansylsarcosine at which half of the Sudlow II binding sites are saturated. The method was applied to a patient database of patients with hepatic failure treated with OPAL or MARS liver support systems (albumin dialysis with albumin regeneration). The applied analysis focused on the correlation with existing clinical scores and the description of therapeutic effects. Results The new method correlates with established markers, scores and therapeutic effects. For Patient samples from the OPALESCE database, Bmax and Kd exhibited correlations with established albumin biomarkers. Subgroup analysis revealed associations with clinical scores such as GCS, SOFA, MELD, ACLF, CLIF-OF and ABiC emphasizing the clinical relevance of Bmax and Kd values. Therapeutic effects were assessed using the OPALESCE database, demonstrating the capability of Bmax and Kd to describe therapy outcomes. Significant differences between the start and end of the first treatment were detected for MARS with Bmax and OPAL with Kd. Bmax and Kd values proved to be valuable indicators for therapeutic effects, aligning with established parameters such as ABiC and the CLIF-OF Score. These findings underscore the potential clinical utility of Bmax and Kd as robust markers for assessing therapy outcomes in liver support interventions. Conclusion The results help to provide a comprehensive understanding of albumin binding dynamics in patients with hepatic failure, offering a valuable tool for therapeutic decisions. The impact of therapy can be described using Bmax and Kd, both of which correlate with established clinical scores within the patient population. Bmax unveils irreversible damages to the albumin molecule, showcasing its potential to identify scenarios where applied therapies fail to enhance albumin binding functions. This insight prompts the consideration of alternative therapeutic pathways, including the consideration of therapeutic plasma exchange when extracorporeal methods are insufficient, showcasing the biomarker's utility in guiding precision therapeutic decisions for improved outcomes in hepatic failure management. The significance of albumin function for uraemic toxins needs to be further investigated. Optimization of dialysis for patients with renal insufficiency appears possible.

Trends and outcomes in the surgical management of young adults with knee osteoarthritis using high tibial osteotomy and unicompartmental knee arthroplasty.

A significant portion of knee osteoarthritis is diagnosed in patients under the age of 55, where greater activity demands make total knee arthroplasty less desirable. High tibial osteotomy (HTO) and unicompartmental knee arthroplasty (UKA) are useful alternatives, but there is little understanding of which procedure is advantageous. Hence, this study examines the utilization, complication, and reoperation rates among the HTO vs. UKA in young patients with primary osteoarthritis. A retrospective review of the National Surgical Quality Improvement Program was performed to identify 2318 patients < 55years of age who received either a HTO or UKA for primary osteoarthritis between 2011 and 2021. Bivariate analyses compared preoperative and intraoperative characteristics among each procedure. Then, multivariate analyses examined if either procedure was associated with worse 30-day postoperative complications or need for reoperation, independent of the statistically significant pre- and intraoperative disparities. UKAs were performed 14.2 times more commonly than HTOs, and the patients selected for HTO were more likely to be younger, have a lower BMI, have the healthiest ASA Class score, and less likely to have hypertension requiring medication (p < 0.001). HTOs took 17.5% longer to perform and had a longer average length of stay (p < 0.001), while UKAs were more likely to be performed out-patient (p < 0.001). HTOs also had higher rates of serious complications (p = 0.02), overall complications (p = 0.004), and need for reoperation (p = 0.004). Multivariate modelling demonstrated that procedure type was not a predictor of serious complications, but the use of HTO was significantly associated with any complications (odds ratio = 3.63, p = 0.001) and need for reoperation (3.21, p = 0.029). Although healthier patients were selected for HTOs, UKAs were found to have a lower risk of complications and immediate reoperation. Additionally, UKAs had the advantage of lower operative burden, shorter length of stay, and a higher efficacy in outpatient settings.

Data collection included demographics, echocardiographic assessments, and detailed angiogram analysis. Statistical analysis was performed using SPSS version 23.0, with a significance threshold set at p&lt;0.05. Results: The overall prevalence of ISR was found to be 18.63%. Diabetes and hypertension showed a significant association with ISR, with p-values &lt;0.0015. The ISR frequencies for single vessel disease (SVCAD), double vessel disease (DVCAD), and triple vessel disease (TVCAD) were 26.32%, 31.58%, and 42.10%, respectively, with TVCAD showing a statistically significant association (p=0.0185). Conclusion: The study highlights a significant association between long DES and increased ISR rates, particularly in patients with complex coronary anatomies and multiple comorbidities. Shorter stents are recommended to potentially reduce restenosis and improve outcomes in CAD management.

Molecular Markers in Melanoma Progression: A Study on the Expression of miRNA Gene Subtypes in Tumoral vs. Benign Nevi.

This study investigates the differential expression of miRNA gene subtypes in tumoral versus benign nevi in individuals with melanoma, aiming to identify clinically significant correlations that could serve as reliable markers for assessing tumor stage and progression. Conducted between 2019 and 2022, this descriptive, quantitative observational research analyzed 90 formalin-fixed paraffin-embedded (FFPE) samples from the Pius Brinzeu County Emergency Clinical Hospital, Timisoara, including 45 samples of advanced-stage melanoma and 45 samples of pigmented nevi. miRNA purification and analysis were performed using the miRNeasy Kit and the Human Cancer PathwayFinder miScript miRNA PCR Array, with statistical analysis (including logistic regression) to determine associations with cancer staging, such as high Breslow index risk, number of mitoses, and vascular invasion. After the analysis and comparison of 180 miRNA gene subtypes, we selected 10 of the most upregulated and 10 most downregulated genes. The results revealed that hsa-miR-133b, hsa-miR-335-5p, hsa-miR-200a-3p, and hsa-miR-885-5p were significantly upregulated in melanoma samples, with fold changes ranging from 1.09 to 1.12. Conversely, hsa-miR-451a and hsa-miR-29b-3p showed notable downregulation in melanoma, with fold changes of 0.90 and 0.92, respectively. Additionally, logistic regression analysis identified hsa-miR-29b-3p (OR = 2.51) and hsa-miR-200a-3p (OR = 2.10) as significantly associated with an increased risk of a high Breslow index, while hsa-miR-127-3p and hsa-miR-451a were associated with a reduced risk. Conclusively, this study underscores the significant alterations in miRNA expression in melanoma compared to benign nevi and highlights the potential of specific miRNAs as biomarkers for melanoma progression. The identification of miRNAs with significant associations to melanoma characteristics suggests their utility in developing non-invasive, cost-effective diagnostic tools and in guiding therapeutic decisions, potentially improving patient outcomes in melanoma management.

The Model Study of Phase-Transitional Magnetic-Driven Micromotors for Sealing Gastric Perforation via Mg-Based Micropower Traction.

Gastric perforation refers to the complete rupture of the gastric wall, leading to the extravasation of gastric contents into the thoracic cavity or peritoneum. Without timely intervention, the expulsion of gastric contents may culminate in profound discomfort, exacerbating the inflammatory process and potentially triggering perilous sepsis. In clinical practice, surgical suturing or endoscopic closure procedures are commonly employed. Magnetic-driven microswarms have also been employed for sealing gastrointestinal perforation. However, surgical intervention entails significant risk of bleeding, while endoscopic closure poses risks of inadequate closure and the need for subsequent removal of closure clips. Moreover, the efficacy of microswarms is limited as they merely adhere to the perforated area, and their sealing effect diminishes upon removal of the magnetic field. Herein, we present a Fe&Mg@Lard-Paraffin micromotor (LPM) constructed from a mixture of lard and paraffin coated with magnesium (Mg) microspheres and iron (Fe) nanospheres for sutureless sealing gastric perforations. Under the control of a rotating magnetic field, this micromotor demonstrates precise control over its movement on gastric mucosal folds and accurately targets the gastric perforation area. The phase transition induced by the high-frequency magnetothermal effect causes the micromotor composed of a mixed oil phase of lard and paraffin to change from a solid to a liquid phase. The coated Mg microspheres are subsequently exposed to the acidic gastric acid environment to produce a magnesium protonation reaction, which in turn generates hydrogen (H2) bubble recoil. Through a Mg-based micropower traction, part of the oil phase could be pushed into the gastric perforation, and it would then solidify to seal the gastric perforation area. Experimental results show that this can achieve long-term (>2 h) gastric perforation sealing. This innovative approach holds potential for improving outcomes in gastric perforation management.

A randomized controlled trial examining general parenting training and family-based behavioral treatment for childhood obesity: The ReFRESH study design

Family-based behavioral treatment (FBT) is one of the most effective treatments for childhood obesity. These programs include behavior change strategies and basic parenting training to help parents make healthy diet and physical activity changes for their children. While effective, not all families respond to this program. Additional training on how to effectively deliver these behavior change strategies may improve outcomes. The authoritative parenting style is associated with many positive academic and socio-emotional outcomes in children, and is characterized by displays of warmth and support while also being consistent with setting limits and boundaries. This parenting style has also been associated with normal weight status. Furthermore, parenting training programs that promote this parenting style for children with behavioral issues have shown unintended effects on decreasing child weight status. Therefore, our goal was to examine the effect of adding more intensive parenting training to FBT on child weight status. We randomized 140 children and their parent to either FBT or FBT + Parenting Training (FBT + PT). Assessments were conducted at baseline, mid-treatment (month 3), post-treatment (month 6), 6-month follow-up (month 12), and 12-month follow-up (month 18). Primary outcome was change in child weight status. Secondary outcomes were rates of drop-out, treatment adherence, and acceptability. If effective, this program may provide another alternative for families to help improve outcomes in childhood obesity management.

An assessment of pharmacist perceptions and experiences with community health workers

BackgroundThe American Public Health Association defines a community health worker (CHW) as “a trusted member of and/or has an unusually close understanding of the community served.” Both CHWs and pharmacists have shown they are well-equipped to produce positive outcomes in chronic disease management, but there is still a gap in the literature regarding the CHW-pharmacist relationship. ObjectiveThe objective of this study was to assess and describe pharmacist perceptions and experiences with CHWs. MethodsAn online survey was distributed to pharmacists via state and national pharmacy organizations in the following states: Illinois, Indiana, Iowa, Minnesota, Nebraska, and Wisconsin. Descriptive statistics were used to summarize demographics and pharmacist experiences with CHWs. ResultsThe survey received 241 responses and 212 (88.0%) met inclusion criteria. Of the 212 eligible respondents, the survey was sufficiently completed by 163 (76.9%). These 163 complete responses were included in the data analysis. Fifty-eight (35.6%) respondents reported working with a CHW and 105 (64.4%) reported never working with a CHW. Fifty-two (89.7%) respondents who previously worked with a CHW were strongly interested or interested in continuing to work with a CHW. Sixty-one (58.1%) respondents without experience were strongly interested or interested in working with a CHW. The reported improvements seen with the addition of a CHW to the healthcare team included: improved patient empowerment, improved clinical patient outcomes, decreased workload of other health care professionals, increased healthcare knowledge, increased healthcare utilization, and increased medication and/or treatment plan adherence. ConclusionPharmacists recognize the benefit of working with a CHW and their contributions to patient care and want to continue working collaboratively. Collaborative pharmacist-CHW relationships should be a priority for optimizing care through community pharmacies and will require a shift in the current structure of community pharmacy services.

Approach to duodenal pathology in bariatric surgery: Transit bipartition as an option

Transit bipartition (TB) emerges as a bariatric surgery alternative to Duodenal Switch (DS), emphasizing complete intestinal access and reduced malabsorption. By directly stimulating the distal ileum, TB promotes weight loss while preserving endoscopic duodenal access.

TB shows favorable short-term outcomes in weight management and comorbidity reduction, serving as a simpler, less malabsorptive option than DS. Nonetheless, long-term studies are essential for comprehensive efficacy assessment.

Real-World Data Analysis of CDK4/6 Inhibitor Therapy-A Patient-Centric Single Center Study.

The quest to comprehend the real-world efficacy of CDK4/6 inhibitors (CDKis) in breast cancer continues, as patient responses vary significantly. This single-center retrospective study evaluated CDKi use outside the trial condition from November 2016 to May 2020. Progression-free survival (PFS), time-to-treatment failure (TTF), short-term and prolonged treatment benefit (≥4 and ≥10 months), as well as prognostic and predictive markers were assessed with Kaplan-Meier and multivariate regression analyses. Out of 86 identified patients, 58 (67.4%) had treatment failure of which 40 (46.5%) were due to progression. Median PFS and TTF were 12 and 8.5 months, respectively. A total of 57 (66.3%) and 42 (48.8%) patients experienced short-term and prolonged treatment benefit. Independent, significant predictors for PFS were progesterone receptor expression (HR: 0.88), multiple metastatic sites (HR: 2.56), and hepatic metastasis (HR: 2.01). Significant predictors for TTF were PR expression (HR: 0.86), multiple sites (HR: 3.29), adverse events (HR: 2.35), and diabetes (HR: 2.88). Aside from tumor biology and adverse events, treatment modifications like pausing and switching of CDKi were predictive for short-term (OR: 6.73) and prolonged (OR: 14.27) therapeutic benefit, respectively. These findings emphasize the importance of tailored treatment strategies, highlighting the role of PR expression, metastatic burden, and therapeutic adjustments in optimizing patient outcomes in real-world breast cancer management.
