ge were associated with survival.Intravesical Bacillus Calmette-Guérin vaccine, one of the most successful bio-therapies to date, has been the gold standard treatment for non-muscle invasive bladder cancer for 44 years. International shortages have necessitated rationing this life-saving medication with deleterious effects on the primary treatment of high-grade non-muscle invasive bladder cancer. Understanding the history of intravesical Bacillus Calmette-Guérin gives us insight into the current shortages and future perspectives for novel immunotherapy opportunities against this deadly disease.
Collecting duct carcinoma is a rare pathologic entity with a paucity of clinical data in the literature. We aim to evaluate our institutional experience with the management of this disease.
All renal tumors in the Mayo Clinic Nephrectomy Registry were re-reviewed retrospectively by an expert urologic pathologist. Cases of collecting duct carcinoma were identified. Descriptive statistics were used to characterize these cases. Overall survival and metastases-free survival were estimated using Kaplan-Meier methodology.
Between 1970 and 2018, a total of 21 cases were identified with an incidence of 0.2%. Cases were seen predominantly in men (N = 17, 81%) with a median age at diagnosis of 57 years old. At the time of nephrectomy, high grade disease (grade 3 or 4) was noted in the majority of patients (90%). The median times to local recurrence and distant metastases were 5.6 and 5.1 months, respectively. Median overall survival occurred at 1.5 years. Median distant metastases-free survival among M0 patients occurred at 0.5 years. Four patients with localized disease and small tumor size who underwent nephrectomy lived longer than 10 years. No systemic therapies achieved a durable response in the metastatic setting.
The Mayo Clinic nephrectomy registry contains 21 patients with collecting duct carcinoma over nearly 50 years. Early local recurrence and distant metastases were seen after nephrectomy. However, M0 patients with a small tumor may have long-term benefits from nephrectomy. Neither chemotherapy nor targeted therapy resulted in a durable response in the metastatic setting.

This study aimed to determine the prognostic values of Ki67 and vimentin in upper tract urothelial carcinoma (UTUC) after extirpative surgery.
Between 2014 and 2019, patients diagnosed with UTUC and receiving radical nephroureterectomy were included retrospectively. Nuclear MIB-1 clones and cytoplasmic VIM 3B4 clones were used to assess Ki67 and vimentin levels, respectively. A unified reading protocol was applied, and the expression level was read by a single pathologist. Receiver operating characteristic curves were utilized to determine the best threshold for Ki67 and vimentin regarding recurrence, and this level was set as the diffusive level. The outcome of recurrence-free survival (RFS) was analyzed via a Cox regression model with univariable and multivariable approaches. Survival outcomes were analyzed via Kaplan-Meier (KM) curves.
A total of 247 patients were included, and the mean follow-up was 29.90 ± 6.80 months. Diffusive thresholds were 17.5% for both Ki67 and vimentin. Under multivariable redicting worse RFS in UTUC.A prostate biopsy is essential for prostate cancer diagnosis. However, infections are one of the biopsy-associated complications, and post-biopsy fever is estimated to occur in approximately 1% of all cases. It may thus be beneficial to perform a rectal swab culture before a transrectal prostate biopsy to confirm the presence of resistant bacteria and select preventive antibacterial agents according to the drug susceptibility results. This study aimed to determine whether there is a difference between the drug susceptibility of bacteria detected in the stool of patients who were scheduled to undergo prostate biopsy and the hospital-wide urine antibiogram. Patients suspected of having prostate cancer who underwent transrectal prostate biopsy via transrectal ultrasonography between August 1, 2016, and June 30, 2020, were included in this study. Stool samples were collected and cultured before biopsy. Overall, 99 patients underwent prostate biopsy, and of these, culture results were available for 81 patients (81.8%). Escherichia coli was detected in 74.0% (60 samples) of the stool culture samples, of which 4 samples were extended-spectrum β-lactamase-producing types. We found greater susceptibility of Escherichia coli to ampicillin, fluoroquinolones, sulfamethoxazole/trimethoprim, and cefixime in the stool culture antibiogram than in the hospital-wide urine antibiogram. We also found a significantly low incidence of ESBL-positive Escherichia coli in the stool culture antibiogram with p-values of 0.009, 0.007, and 0.03 compared to the hospital-wide urine antibiograms for 2017, 2018, and 2019, respectively. Stool culture of prostate cancer patients undergoing biopsy may provide useful information for selecting prophylactic antimicrobial agents.
The flexor digitorum superficialis tendon to the little finger (FDS-5) has been observed to have a higher degree of functional and structural variation than the FDS of other digits. FDS-5-deficient individuals necessarily rely on the flexor digitorum profundus tendon to the little finger (FDP-5) for flexion in their little fingers. FDS-5 deficient patients who experience a considerable injury to their FDP-5 are therefore at a risk of losing substantial little finger flexion. The purpose of this study was to evaluate the degree of flexion of the little finger at the metacarpophalangeal and proximal interphalangeal (PIP) joints in a cadaveric model of FDS-5 deficiency following amputation of the distal phalanx.
Ten fresh-frozen cadaveric upper extremities with no prior trauma were used. Loads were applied to the FDP-5. Flexion at the PIP and metacarpophalangeal joints was measured in degrees with a goniometer. ETC-159 chemical structure Little finger flexion testing was conducted under 5 different conditions "baseline," "FDS-deficient that may be applicable in this clinical scenario.
A clinical protocol is yet to be established for the surgical treatment in FDS-5-deficient patients requiring amputation of the distal phalanx of the little finger. This study aims to address this area of uncertainty by comparing the little finger flexion after 2 different approaches to profundus tendon reattachment that may be applicable in this clinical scenario.
Seizures are a common neonatal neurologic emergency. Many centers have developed pathways to optimize management. We evaluated neonatal seizure management pathways at level IV neonatal intensive care units (NICUs) in the United States to highlight areas of consensus and describe aspects of variability.
We conducted a descriptive analysis of 11 neonatal seizure management pathways from level IV NICUs that specialize in neonatal neurocritical care including guidelines for electroencephalography (EEG) monitoring, antiseizure medication (ASM) choice, timing, and dose.
Study center NICUs had a median of 70 beds (interquartile range 52-96). All sites had 24/7 conventional EEG initiation, monitoring, and review capability. Management pathways uniformly included prompt EEG confirmation of seizures. Most pathways included a provision for intravenous benzodiazepine administration if either EEG or loading of ASM was delayed. Phenobarbital 20 mg/kg IV was the first-line ASM in all pathways. Pathways included eitherarch include optimal second-line ASM, dosage, and timing of ASM discontinuation.Animal testing has long been integral to the development of biologicals, including vaccines. The use of animals can provide important information on potential toxicity, insights into their mechanism of action, pharmacokinetics and dynamics, physiologic distribution, and potency. However, the use of these same methods is often adopted into the post-licensure phase of the product life cycle for the monitoring of product qualities, such as potency or safety, as part of their routine batch release. The UK National Centre for the Replacement, Refinement, and Reduction of Animals in Research (NC3Rs) and the World Health Organization (WHO) are collaborating on a project to review animal-based testing methods described in WHO manuals, guidelines and recommendations for biologicals to identify where updates can lead to a more harmonised adoption of 3Rs principles (i.e. Replacement, Reduction, and Refinement of animal tests) in batch release testing requirements. An international working group consisting of more than 30 representatives from pharmaceutical and biotechnology companies, national control laboratories and regulatory bodies is performing this review. This project aims to address concerns about inconsistencies in the guidance for the scientifically justified use of animal methods required for the post-licensure quality control and batch release testing of biologicals, and the near absence of recommendations for the application of 3Rs principles within the relevant guidelines. Improved adoption of 3Rs principles and non-animal testing strategies will help to reduce the delays and costs associated with product release testing and help support faster access to products by the global communities who need them most urgently.
Comparison of nurse involvement in end of life decision making in European countries participating in ETHICUS I- 1999 and ETHICUS II- 2015.
This was a prospective observational study of 22 European ICUs included in the ETHICUS-II and I. Data were collected as per the ETHICUS-I and ETHICUS-II protocols. Four questions within the ETHICUS protocols related to nurse involvement in end of life decision making were analyzed. This is a comparison of changes in nurse involvement in end of life decisions from 1999 to 2015.
International e-based questionnaire completed by an intensive care clinician when an end of life decision was performed on any patient.
Intensive care physicians and nurses, no interventions were performed.
A 20 question survey was used to describe the decision making process, on what basis was the decision made, who was involved in the decision making process, and what precise decisions were made.
A total of 4592 cases from 22 centres are included. While there was more agreement between nurses and physicians in ETHICUS-I compared to ETHICUS-I, fewer discussions with nurses occurred in ETHICUS-II. The frequency of end of life decisions that were discussed with nurses decreased in all three regions between ETHICUS-I and ETHICUS-II.
Based on the results of the current study, nurses should be further encouraged to increase their involvement in end of life decision-making, especially those in southern Europe.
