Summary: This study aimed to evaluate the association between ACE gene I/D polymorphisms, circulating levels of Ang II, and CAKUT. The study concluded that ACE I/D polymorphisms were not associated with CAKUT or specific CAKUT phenotypes, and there were no significant differences in plasma levels of Ang II between CAKUT patients and controls.

Summary: Vesicoureteral reflux (VUR) is a common urological problem in children with a hereditary nature. Whole-exome sequencing in 13 large families with at least three affected cases revealed 23 deleterious variants in 19 candidate genes associated with VUR or nephrogenesis. This study demonstrates a likely causal gene variant in 23% of the families and highlights the usefulness of whole-exome sequencing in understanding the pathogenesis and improving molecular diagnostics of VUR.

Summary: This study aims to introduce a new radiological score based on fMRU findings to differentiate surgical from non-surgical kidneys with UPJO. The study found that urographic phase, presence of abnormal vessels, and baseline anterior-posterior pelvic diameter >23 mm were significantly associated with surgery. The score showed high sensitivity and specificity in distinguishing surgical from non-surgical kidneys.

Summary: Ureteropelvic junction obstruction (UPJO) is a common cause of prenatal diagnosed hydronephrosis, with recent studies focusing on the use of ultrasound classification systems and MRI to stratify the risk in infants. Urinary biomarkers have also shown potential as a noninvasive alternative in identifying infants with clinically significant UPJO. Further research is needed to establish clear guidelines for evaluation and treatment to improve long-term outcomes for these patients.

Summary: This study investigated the clinical factors associated with vesicoureteral reflux (VUR) in Taiwanese children with a first documented urinary tract infection (UTI). The results showed that age <1 year, renal anomalies, hydronephrosis, duplex collecting system/ectopic kidney/ectopic ureter, neuropathic bladder, and spina bifida were independent factors for VUR. Early diagnosis of VUR through ultrasound and voiding cystourethrography is important to prevent renal damage.

Summary: Primary vesicoureteral reflux (VUR) is a common congenital anomaly in children, and this study identified genetic factors contributing to the condition. PAX2, TNXB, GATA3, and SLIT2 were found to be major genes associated with VUR, impacting renal survival. Extrarenal complications and impaired renal function were related to genetic factors, suggesting multiple genes may be responsible for isolated VUR.

Summary: In this study, a simple in vitro bladder model was designed to simulate the dynamics of filling and voiding. The physio-mechanical condition of the model was verified using pressure-flow and reflux tests. Encrustation tests with artificial urine on double-J stents were conducted using the model, and the volumes of luminal encrustations were quantified. The results suggest that VUR is an important factor contributing to the dynamics in the upper urinary tract with indwelling stents, emphasizing its significance in future in vitro studies and clinical analyses.

Summary: This paper presents novel umbrella-shaped flexible devices for preventing vesicoureteral reflux, particularly in patients with urinary stones. The devices mechanically attach to the stent and have been shown to be effective through experiments. The penta-shaped device exhibited the best anti-reflux performance, with maximum efficiency achieved when attached at a specific location.

Summary: The aim of this study was to determine whether early measurements of serum aldosterone levels or plasmatic renin activity (PRA) could predict the need for surgical intervention in infants with obstructive congenital anomalies of kidney and urinary tract (CAKUT). A total of 20 infants aged 1-3 months with suspected obstructive CAKUT were prospectively enrolled and followed up for 2 years. The results showed that infants who required surgery had significantly higher levels of aldosterone at 1-3 months compared to those who did not require surgery (p = 0.006). The ROC curve analysis identified a cut-off of 100 ng/dL for aldosterone, which predicted the need for surgery with 100% sensitivity and 64.3% specificity. However, PRA measured at 1-3 months was not a predictor of surgery. In conclusion, early measurements of serum aldosterone levels can serve as a predictor for surgical intervention in infants with obstructive CAKUT.

Biallelic variants may impact receptor molecule function, while monoallelic variants may interfere with downstream signaling through a dominant-negative effect.

Summary: The current clinical standard-of-care for heart transplant acute rejection (AR) relies on histopathological assessment, but this study demonstrates that adding RNA sequencing analysis of endomyocardial biopsies (EMBs) can improve the sensitivity and specificity of diagnosis. Furthermore, the study shows that transcriptional hallmarks of rejection can be detected months before the actual event, which is not visible using traditional histopathology.

Summary: Alport syndrome is an inherited kidney disease that affects males more severely than females and is sometimes associated with hearing loss. Three genes responsible for the disease were discovered in the late twentieth century. The international workshops in 2019 and 2021 discussed various topics related to the syndrome, including disease renaming, increasing the diagnostic rate, genotype-phenotype correlation, new therapeutics, and gene therapy.

Summary: Single-cell ATAC-seq and RNA-seq profiling were used to study the transformation process from healthy colon to precancerous adenomas to colorectal cancer. Most of the polyp and CRC cells exhibited a stem-like phenotype. The study identified a continuum of epigenetic and transcriptional changes that occur in stem-like cells as they progress from homeostasis to CRC. The results also revealed the presence of T cell exhaustion and specific fibroblast subtypes in advanced polyps and cancerous states. Additionally, DNA methylation changes were found to be negatively correlated with accessibility changes, providing potential regulatory markers for polyp staging.

Summary: This study investigated the deposition of copper-cobalt tin sulfide thin films using a sol-gel spin-coating method. The annealing process at 300 degrees C in a nitrogen atmosphere for 60 minutes was found to produce pure CCTS thin films with promising properties for low-cost thin-film solar cells.

Summary: In this study, the structural, electrical, and optical properties of barium titanate (BaTiO3) and lead titanate (PbTiO3) were investigated using the plane wave pseudopotential method and the PBESOL approximation in the framework of density functional theory (DFT). The calculations using different types of pseudopotentials show good agreement with experimental values, especially for ultrasoft pseudopotentials (USPP) and projector-augmented wave (PAW) pseudopotentials.

Summary: This study analyzed kidney biopsies from type 2 diabetes patients and healthy controls, and found that SGLT2 inhibitor treatment mitigates diabetes-induced metabolic perturbations through suppression of the mTORC1 signaling pathway in kidney tubules. The treatment with SGLT2 inhibitors also affected transcriptional processes in different segments of the renal tubules.

Summary: This case report discusses a patient with CHI. The study found two activity peaks in the patient's pancreas, and surgical resection of these areas resulted in normalized blood sugar levels. Analysis of tissue samples indicated that a second genetic hit in pancreatic precursor cells was responsible for the atypical pancreatic lesion. The study confirms that the resection of focal lesions can lead to complete cure in CHI patients.

Summary: This study describes eight children with Pontocerebellar hypoplasia (PCH) from four unrelated families carrying homozygous variants in the MINPP1 gene. These variants result in either a complete absence of MINPP1, impaired protein folding, destabilization of protein structure or reduction in protein stability, leading to the pathogenesis of the disease. This study presents MINPP1 as a novel autosomal recessive gene associated with PCH.
