Evaluation of functional and oncological outcomes of localized prostate cancer after different minimally invasive therapeutic methods: A single center experience.

OBJECTIVES: To study the functional and oncological results of minimally invasive treatment methods: cryoablation, brachytherapy, and high-intensity focused ultrasound (HIFU) therapy of localized prostate cancer in a single hospital. METHODS: One hundred sixty patients with localized prostate cancer were treated with minimally invasive methods (53, 52, 55 patients with cryoablation, brachytherapy and HIFU therapy, respectively). Prostate-specific antigen and evaluation of post-procedure biopsies were used as an assessment. The review of functional indicators and quality of life was made with International Index of Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), quality of life (QoL) questionnaires. RESULTS: Patients after cryoablation showed worse results of oncological control according to positive repeat biopsies, best indicators were observed after brachytherapy. When considering the IPSS results, there were statistically significantly worse scores in the brachytherapy group in the early postoperative period, these differences do not reach statistical significance in the late period in the brachytherapy and cryoablation groups. Patients in the cryoablation group showed worse indicators of IIEF-5; in the early postoperative period; in the late follow-up period, the indicators of erectile function in patients in the cryoablation group did not statistically significantly differ from those in patients after brachytherapy. Patients after HIFU therapy showed fewer cases of de novo erectile dysfunction during the follow-up period of 3 years, higher average IIEF-5 scores, lower IPSS scores and better QoL results. CONCLUSION: The recurrence of prostate cancer was statistically significantly higher in the International Society of Urological Pathology (ISUP) 3 grade group. HIFU therapy had better urination indicators compared to other groups, that can be associated with the laser enucleation of prostatic hyperplasia. The advantage was noted in patients after HIFU therapy when comparing the parameters to the IIEF-5 thus, HIFU treatment had a better impact on patients' QoL with localized prostate cancer.

Macrophage Transcriptional Profile Identifies Lipid Catabolic Pathways That Can Be Therapeutically Targeted after Spinal Cord Injury.

Although infiltrating macrophages influence many pathological processes after spinal cord injury (SCI), the intrinsic molecular mechanisms that regulate their function are poorly understood. A major hurdle has been dissecting macrophage-specific functions from those in other cell types as well as understanding how their functions change over time. Therefore, we used the RiboTag method to obtain macrophage-specific mRNA directly from the injured spinal cord in mice and performed RNA sequencing to investigate their transcriptional profile. Our data show that at 7 d after SCI, macrophages are best described as foam cells, with lipid catabolism representing the main biological process, and canonical nuclear receptor pathways as their potential mediators. Genetic deletion of a lipoprotein receptor, CD36, reduces macrophage lipid content and improves lesion size and locomotor recovery. Therefore, we report the first macrophage-specific transcriptional profile after SCI and highlight the lipid catabolic pathway as an important macrophage function that can be therapeutically targeted after SCI.SIGNIFICANCE STATEMENT The intrinsic molecular mechanisms that regulate macrophage function after spinal cord injury (SCI) are poorly understood.

Foregut Duplication Cyst of the Stomach: A Case Report and Review of the Literature.

Duplication cyst of the stomach is a rare congenital malformation, typically diagnosed in the first year of life. In most adult cases the cyst remains asymptomatic, but patients may present with abdominal symptoms including epigastric discomfort or pain. We present a case of a 65-year-old male with an asymptomatic gastric tumor diagnosed incidentally during initial workup of his esophageal adenocarcinoma. Computed tomography revealed a low density soft tissue tumor near the gastroesophageal junction. Endoscopic ultrasonography demonstrated a cystic lesion as a hypoechoic round mass with well-defined borders. Following complete laparoscopic resection, microscopic review revealed a cyst lined with respiratory pseudostratified ciliated columnar epithelium and layers of smooth muscle with an outermost thin fibrous capsule consistent with a foregut duplication cyst.
