Promising Therapeutic Targets for Recurrent/Metastatic Anaplastic Thyroid Cancer.

OPINION STATEMENT: Anaplastic thyroid cancer presents formidable challenges, particularly in cases of recurrence or metastasis. Timely BRAF V600E testing is imperative at diagnosis, initially through immunohistochemistry, followed by comprehensive genomic profiling encompassing genes such as NTRK, RET, ALK, and assessment of tumor mutation burden (TMB). FDA-approved treatment options include dabrafenib and trametinib for patients with BRAF mutations, while those exhibiting high TMB may benefit from pembrolizumab. Further therapeutic decisions hinge upon mutational profile, urgency of response required, airway integrity, and access to targeted therapies There is growing use of immunotherapy for ATC based on published reports of activity, but currently there is no FDA approved agent for ATC. The off-label utilization of "precision medicine" combinations imposes a considerable financial strain, underscoring the necessity for further clinical trials to elucidate promising therapeutic avenues for this orphan disease. There is a pressing need for the development and support of clinical trials investigating genomically driven and immune-based therapies for anaplastic thyroid cancer.

Outcomes of balloon angioplasty and stent placement for iliac artery lesions classified as TASC II A, B: a single-center study.

Background: Iliac artery stenosis or occlusion is a critical condition that can severely impact a patient's quality of life. The effectiveness of balloon angioplasty and intraluminal stenting for the treatment of iliac artery lesions classified as TASC II A and B was evaluated in this single-center prospective study. Methods: Conducted between October 2016 and September 2020 at Cho Ray Hospital's Vascular Surgery Department, this prospective study involved PAD patients categorized by TASC II A and B classifications who underwent endovascular intervention. Intervention outcomes were assessed peri-procedure and during short-term and mid-term follow-ups. Results: Of the total of 133 patients, 34.6% underwent balloon angioplasty, while 65.4% received stenting. The immediate technical success rate was 97.7%, while the clinical success rate was 62.4%. Complications were minimal, with major limb amputation reported in 1.5% of the cases. There was a significant improvement in Rutherford classification and ABI at short-term follow-up, with a patency rate of 90.2%. The mid-term post-intervention follow-up yielded similar results with an 86.1% patency rate. The mortality rates associated with arterial occlusion were 2.3% during short-term follow-up and 1.7% during mid-term follow-up. Conclusion: Balloon angioplasty and stent placement are effective and safe interventions for TASC II A and B iliac artery occlusions with favorable short and mid-term outcomes. Further, multi-center studies with larger sample sizes are recommended for more comprehensive conclusions, including long-term follow-up assessment.

Trends in substance-induced cardiomyopathy-related mortality among older adults in the United States from 1999 to 2020.

In this retrospective study, spanning from 1999 to 2020, we examined mortality trends related to SICM (substance-induced cardiomyopathy) among individuals aged 75 and older. A total of 473,408 SICM-related deaths were identified, with detailed data on the place of death available for 454,632 cases, revealing that a significant proportion occurred in medical facilities (45.43 %), nursing homes (24.67 %), hospices (4.21 %), and at home (25.69 %). Our analysis of age-adjusted mortality rates (AAMR) showed an overall decline from 1999 to 2020, decreasing from 14.5 to 7.7 per 10,000 population, with an initial increase from 1999 to 2001 followed by a subsequent decline. Gender-based analysis indicated consistently higher AAMRs for elderly men compared to elderly women. Moreover, we observed variations in AAMRs based on race and ethnicity, with NH Black or African American individuals having the highest AAMRs. Geographic disparities were notable, with states like Delaware having AAMRs twice as high as Utah. The Southern region consistently exhibited the highest AAMR, followed by the Midwestern, Northeastern, and Western regions. Furthermore, metropolitan areas consistently had higher AAMRs than nonmetropolitan areas, although both showed declining trends over the study period. These findings provide valuable insights into SICM-related mortality patterns among the elderly population, emphasizing the importance of considering demographic and geographic factors in public health planning and interventions.

Septal Myectomy or Alcohol Ablation for Hypertrophic Cardiomyopathy: A Nationwide Inpatient Sample (NIS) Database Analysis.

BACKGROUND: Comparison of the real-world cohort on the relative safety of alcohol septal ablation (ASA) vs. septal myectomy (SM) for the management of hypertrophic cardiomyopathy (HCM) has been lacking. METHODS: The National Inpatient Sample (NIS) (2012-2019) was used to select all cases of HCM. The safety of ASA vs. SM was compared using a one:many propensity score matched (PSM) analysis. Adjusted odds ratios (aOR) for mortality and other in-hospital complications were computed. RESULTS: A total of 6208 HCM patients (ASA 3106 vs. SM 3102) were included using a PSM analysis. Post-procedural bleeding (aOR 0.18, 95 % CI 0.11-0.32, p < 0.0001) and the need for an intra-aortic balloon pump (aOR 0.51, 95 % CI, 0.28-0.96, p = 0.037) were significantly lower while permanent pacemaker (PPM) implantation was significantly higher in ASA group as compared with SM group (aOR 1.72, 95 % CI, 1.43-2.06, p < 0.0001). The total in-hospital mean adjusted cost and length of stay were also significantly lower in the ASA group. However, there were no significant differences in adjusted odds of all-cause mortality (aOR 0.91, 95 % CI 0.62-1.33, p = 0.61), stroke (aOR 0.91, 95 % CI, 0.59-1.4, p = 0.66), and major bleeding (aOR 1.0, 95 % CI 7.8-1.29, p = 0.99) between the two comparison groups. CONCLUSION: In patients with hypertrophic cardiomyopathy, alcohol septal ablation appears to be an acceptable alternative to septal myectomy due to a lower risk of post-procedural bleeding and the need for an intra-aortic balloon pump. However, ASA confers a higher risk of PPM placement.

Clinical Role of Positron Emission Tomography/Computed Tomography Imaging in Head and Neck Squamous Cell Carcinoma.

Head and neck squamous cell carcinoma (HNSCC) imaging is nearly synonymous with positron emission tomography (PET) scans. Many of the nearly 60,000 newly diagnosed patients with HNSCC in the US-and 900,000 worldwide-will undergo a PET scan, if not multiple, throughout the course of their care. In this review, we describe the clinical utility of PET scans in HNSCC, emphasizing whereby their input is most impactful in improving patient outcomes as well as scenarios whereby PET/CT scans should be avoided. We also describe important considerations for capturing and processing PET scans with a special focus on the important role of tumor volume segmentation, scan timing relative to therapy, and concurrent conditions (eg, COVID-19). In addition, we will illustrate the latest innovations in the management of HNSCC. This article also will delve to exhibit novel potential biomarkers in the management of HNSCC. Finally, we describe future directions for PET imaging, including the advent of novel PET radiotracers as an alternative to 18F-fluorodeoxyglucose (18F-FDG).
