Article Synopsis
  • Renal dysfunction is common in patients with Fontan circulation, with 12% showing renal issues based on eGFR measurements, and 24% based on cystatin C levels.
  • Over an 11-year study, these patients experienced a faster decline in renal function compared to healthy individuals, averaging a drop of 1.36 ml/min/1.73 m/year.
  • Higher levels of NT-proBNP at the start were linked to quicker drops in renal function, and worsened renal function over time was associated with increased mortality rates.

Background: Histopathological analysis is the cornerstone in bladder cancer (BCa) diagnosis. These analysis suffer from a moderate observer agreement in the staging of bladder cancer. Three-dimensional reconstructions have the potential to support the pathologists in visualizing spatial arrangements of structures, which may improve the interpretation of specimen.

Purpose: Confocal laser endomicroscopy (CLE) is a fluorescence-based fiber-optic imaging technique with the potential for intraoperative grading of upper tract urothelial carcinoma (UTUC). This study aims to (1) investigate the prevalence of the previously proposed CLE criteria for bladder cancer in papillary UTUC, (2) estimate the diagnostic value of CLE for UTUC grading and (3) propose a scoring system for a more quantifiable approach of CLE-based grading of UTUC.

Materials And Methods: Ureteroscopic CLE was performed in patients with UTUC.

Kidney-sparing surgery of upper tract urothelial carcinoma (UTUC) requires a stringent follow-up with frequent ureteroscopies. Triage testing could reduce the number of follow-up ureteroscopies and hence minimize the invasiveness of follow-up. The use of urine-based markers for triage seems appealing but should be feasible with selective urine from outpatient cystoscopy to maximize the reduction of invasiveness.

Background: Cystoscopy enables the visualisation of suspicious bladder lesions but lacks the ability to provide real-time histopathologic information. Confocal laser endomicroscopy (CLE) is a probe-based optical technique that can provide real-time microscopic images. This high-resolution optical imaging technique may enable real-time tumour grading during cystoscopy.

Purpose: Traditionally, transurethral resection of bladder tumors (TURB) is performed using monopolar technique. Bipolar resection has been postulated to reduce complications. In this study we compare safety and efficacy between monopolar TURB (mTURB) and bipolar TURB (bTURB) for patients with primary non-muscle invasive bladder cancer (NMIBC).

Background: Visual confirmation of a suspicious lesion in the urinary tract is a major corner stone in diagnosing urothelial carcinoma. However, during cystoscopy (for bladder tumors) and ureterorenoscopy (for tumors of the upper urinary tract) no real-time histopathologic information can be obtained. Confocal laser endomicroscopy (CLE) is an optical imaging technique that allows for in vivo high-resolution imaging and may allow real-time tumor grading of urothelial lesions.

Article Synopsis
  • A notable portion of bladder cancer patients treated with BCG immunotherapy do not respond positively, highlighting the need for markers to identify potential responders.
  • A multicenter study evaluated the effectiveness of the UroVysion FISH test in predicting bladder cancer recurrence during BCG treatment by analyzing bladder washouts at different time points.
  • Findings revealed that a positive FISH test three months after TURB was significantly linked to a 4.0-4.6 times higher risk of recurrence, suggesting that FISH could serve as a valuable tool in guiding treatment strategies for these patients.

Purpose Of Review: The recurrence rate in patients with nonmuscle invasive bladder cancer is high, and the quality of transurethral resection of the bladder (TURB) tumour influences recurrence risk. We review new methods that aim to improve the effectiveness of TURB, and highlight studies of the past year.

Recent Findings: Several approaches have been explored: bipolar resection is well tolerated and efficient; however, surgical outcomes are not clearly superior to monopolar resection; en-bloc resection seems feasible and well tolerated, and has the potential to improve the quality of tissue for histopathology; enhancement techniques such as photodynamic diagnosis, narrow band imaging, and Image1 S improve tumour detection, whereas photodynamic diagnosis reduces recurrence rates; high-resolution imaging modality such as confocal laser endomicroscopy may provide histopathologic information.

Article Synopsis
  • Participants experienced thick and sticky saliva after exercise, leading to a dry mouth feeling due to increased salivary viscosity.
  • The study involved 20 dental students who cycled for 15 minutes while their saliva was collected before, immediately after, and 30 minutes post-exercise.
  • Results showed that salivary viscosity and MUC5B concentration increased right after exercise, suggesting that thick saliva is partially caused by higher levels of MUC5B secretion during physical activity.

Objective: To determine the prevalence of congenital heart defects (CHDs) in patients with mild or severe congenital anorectal malformations (CARMs), and whether all patients with CARM need pediatric cardiology screening.

Study Design: We included 129 patients with CARM born between 2004 and 2013, and referred to University Medical Center Groningen. Recto-perineal and recto-vestibular fistulas were classified as mild CARMs, all others as severe.

Non-muscle-invasive bladder cancer (NMIBC) is characterised by a high risk of recurrence for the present standard treatment of transurethral resection of the bladder (TURB) followed by intravesical instillation of Mitomycin-C (MMC) or bacillus Calmette-Guérin (BCG). To decrease this high recurrence rate, alternative treatments are studied. Intravesical MMC combined with hyperthermia could be an interesting alternative active treatment for intermediate- and high-risk NMIBC, and has been investigated in the past years.

Objective: To assess whether waist-to-height-ratio (WHtR) is a better estimate of body fat percentage (BF%) and a better indicator of cardiometabolic risk factors than BMI or waist circumference (WC) in young children.

Methods: WHtR, WC and BMI were measured by trained staff according to standardized procedures. (2)H2O and (2)H2(18)O isotope dilution were used to assess BF% in 61 children (3-7 years) from the general population, and bioelectrical impedance (Horlick equation) was used to assess BF% in 75 overweight/obese children (3-5 years).

Using functional MRI, we assessed activity in the human cerebellum related to the properties of post-saccadic visual errors that drive the plasticity of saccadic eye movements. In the scanner subjects executed blocks of saccadic eye movements toward a target that could be randomly displaced during the saccade. Such an intra-saccadic shift was randomly forward or backward, and could be either small or large.

Background: Red hair color is caused by variants of the melanocortin-1 receptor (MC1R) gene. People with naturally red hair are resistant to subcutaneous local anesthetics and, therefore, may experience increased anxiety regarding dental care. The authors tested the hypothesis that having natural red hair color, a MC1R gene variant or both could predict a patient's experiencing dental care-related anxiety and dental care avoidance.

Background/objectives: Both intra-abdominal adipose tissue (IAAT) and subcutaneous abdominal adipose tissue (SAAT) are associated with cardiovascular risk factors, even in childhood. Currently, the gold standard in assessing IAAT and SAAT is computed tomography (CT), which is not widely applicable. The aim of this study was to estimate abdominal fat using anthropometry, dual-energy X-ray absorptiometry (DEXA) and ultrasound, and compare these estimates with the amounts of IAAT and SAAT determined by CT in 6 to 7-year-old children.
