Limited retrospective studies have associated IDC and cribriform morphology with germline mutations in DNA repair genes, particularly BRCA2. These findings, which prompted the National Comprehensive Cancer Network (NCCN) Guidelines for Prostate Cancer and Genetic/Familial High- Risk Assessment to consider germline testing for individuals with IDC/cribriform histology, have been questioned in a recent prospective study. A deepened understanding of the molecular mechanisms driving disease aggressiveness in cribriform morphology is critical to provide more clarity in clinical decision making. This review summarizes the current understanding of IDC and cribriform prostate cancer, with an emphasis on clinical outcomes and molecular alterations.
To understand the histologic changes of prostate tissue induced by temporary implantable nitinol device (cTIND) in a canine model.

The cTIND is a small, symmetric device comprised of nitinol wire loops welded together on an axis, which exert radial force on the tissue to induce a targeted ischemic effect. The cTIND was implanted in three live canine models, which were monitored for 14 days post-index procedure. Device placement was monitored via serial fluoroscopy and biologic effects of cTIND were studied via histopathology.

The cTIND was successfully placed in the canine models and remained securely in position until the animal was sacrificed on postoperative day 14. The cTIND treated tissue demonstrated an abrupt transition from normal, viable prostatic glandular tissue to an area of shrunken necrosis and fibrosis between the two.

In the canine models, the cTIND created focal areas of ischemic necrosis resulting in incisions in the peri-urethral prostate with minimal inflammation.

To assess both short- and long-term constipation symptoms and their impact on quality of life in patients who underwent radical cystectomy (RC) with three different types of urinary diversion orthotopic neobladder (ONB), continent cutaneous diversion (CCD), and ileal conduit (IC).

The validated Patient Assessment of Constipation Symptoms (PAC-SYM) and Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaires were administered to all patients at follow-up greater than 30 days from surgery. Clinical and pathological characteristics were prospectively recorded in an institutional review board approved bladder cancer database. Using multivariable linear regression analyses, we determined significant predictors of improved constipation symptoms and quality of life scores.

A total of 198 patients completed 255 PAC-SYM and PAC-QOL questionnaires with a median follow-up time of 1.7 years (IQR 0.7 - 3.0 years). ONB, CCD, and IC were performed in 78%, 5.5%, and 16.5% of patients, respectively. H after the surgery.
To describe the use of robotic-assisted transplant ureteral repair (RATUR) for treating transplant ureteral stricture (TUS) in 3 patients who had undergone robot assisted kidney transplant (RAKT).

We reviewed the medical records of 3 patients who experienced TUS after RAKT and who underwent RATUR between 2017 and 2020. The patients' RAKT, post-transplant clinical course, endourological interventions, reoperation, and recovery were assessed.

All patients diagnosed with TUS presented with deterioration of kidney function after RAKT. Method of diagnosis included ultrasound, antegrade ureterogram, and CT scan. All 3 patients had a short (<1 cm) area of TUS and underwent RATUR. For 2 patients, distal strictures were bypassed with modified Lich-Gregoir ureteroneocystostomy reimplantation. One patient was treated with pyelo-ureterostomy to the contralateral native ureter. No intraoperative complications, conversions to open surgery, or significant operative blood loss requiring blood transfusion for any patient were observed. Also, no patients had urine leaks in the immediate or late postoperative period. After RATUR, 2 patients developed Clavien grade II complications with rectus hematoma or urinary tract infection.

RATUR is a technically feasible operation for kidney transplant patients with TUS after RAKT. This procedure may provide the same benefits of open operation without promoting certain comorbidities that may occur from open surgical procedures.

Overactivity of the Renin-Angiotensin-Aldosterone-System (RAAS) is a common cause and usually results from an induced physiologic response. Trichostatin A in vivo However, conditions do exist that involve autonomous renin production. Juxtaglomerular cell tumors (JGCT), or reninomas, are renal lesions that cause refractory hypertension via this mechanism. Symptoms and lab abnormalities usually subside with surgical resection of these tumors. Here, we present a case of a 13-year old female with uncontrolled hypertension secondary to reninoma treated with partial nephrectomy, with focus on initial presentation, diagnostic evaluation, and surgical management of this uncommon tumor.Proteins from food-grade expression systems can be used in food products and medical applications. Herein, we describe a one-step method of constructing an expression vector in Kluyveromyces lactis by combining a URA3-deficient strain and a plasmid vector with no drug-resistant selection. Adjacent DNA elements of the vector were assembled in a targeted manner through a reaction with a special recombinase to form a plasmid vector using a one-step reaction. The unnecessary fragments containing the pUC origin and the ampicillin resistance gene were removed, and the vector was isolated and purified before transformation. A single transformation of the vector can produce a URA3-deficient strain. PCR assay, sequencing, and western blot analysis all indicated that the method of vector construction and target protein expression (mCherry and human serum albumin) were successful. This method may potentially be applied to any species containing the URA3 gene; this system has the potential to become a safe and powerful tool for promoting protein expression in food-safe species.
