The aim was to determine the predictive role of combined screening for late-onset gestational hypertension by fetal ultrasound measurements, third trimester uterine arteries (UtAs) Doppler imaging, and maternal history. This prospective study on singleton pregnancies was conducted at the tertiary center of Maternal and Fetal Medicine of the University of Padua during the period between January 2012 and December 2014. Ultrasound examination (fetal biometry, fetal wellbeing, maternal Doppler study, fetal abdominal aorta intima-media thickness [aIMT], and fetal kidney volumes), clinical data (mother age, prepregnancy body mass index [BMI], and parity), and pregnancy outcomes were collected...

A renal angiomyolipoma (AML) is a rare benign tumour of kidney origin. Pregnancy is known to be associated with an increased risk of tumour rupture causing hypovolaemic shock, which is usually managed surgically or through an embolisation procedure. However, having surgery during pregnancy predisposes the mother to a preterm delivery, and the unknown influences of radiation exposure to the fetus make the management of such cases very challenging. A 30-year-old pregnant woman had a sudden onset of gross haematuria at the 20th week of her pregnancy...

Objective: To investigate the value of MRI in the prenatal diagnosis of abnormal fetal kidneys. Methods: From December 2014 to March 2016, 51 women underwent MRI and were confirmed as having fetuses with abnormal fetal kidneys when follow up. Their clinical and MRI profiles were analyzed retrospectively, including MRI manifestation, the fetal kidney signal intensity of diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC). The signal intensity of DWI and ADC of the abnormal kidney and the normal opposite kidney, and those of the normal and abnormal kidneys in different individuals were compared...

Emerging evidence highlights the far-reaching consequences of high-fat diet (HFD) and obesity on kidney morphological and functional disorders. In the present study, we aim to evaluate the effects of early HFD intake on renal function and morphology in maternal protein-restricted offspring (LP). LP and normal protein-intake offspring (NP) were fed HFD (LPH and NPH, respectively) or standard rodent (LPN and NPN) diet from the 8th to 13th week of age. Blood pressure, kidney function, immunohistochemistry and scanning electron microscopy were analyzed...

Melatonin synchronizes central but also peripheral oscillators (fetal adrenal gland, pancreas, liver, kidney, heart, lung, fat, gut, etc.), allowing temporal organization of biological functions through circadian rhythms in relation to periodic environmental changes and therefore adaptation of the individual to his/her internal and external environment. Measures of melatonin are considered the best peripheral indices of human circadian timing. First, the pharmacology of melatonin (biosynthesis and circadian rhythms, pharmacokinetics and mechanisms of action) is described, allowing a better understanding of the short and long term effects of melatonin following its immediate or prolonged release...

The effect of clinically recovered AKI (r-AKI) on future pregnancy outcomes is unknown. We retrospectively studied all women who delivered infants between 1998 and 2007 at Massachusetts General Hospital to assess whether a previous episode of r-AKI associated with subsequent adverse maternal and fetal outcomes, including preeclampsia. AKI was defined as rise in serum creatinine concentration to 1.5-fold above baseline. We compared pregnancy outcomes in women with r-AKI without history of CKD (eGFR>90 ml/min per 1...

INTRODUCTION: Obstructive uropathies are main diseases affecting the fetus. Early diagnosis allows to establish the appropriate therapy to minimize the risk of damage to kidney function at birth. Biochemical markers have been used to predict the prognosis of renal function in fetuses. Uromodulin, also known by Tamm-Horsfall protein (THP) is exclusively produced in the kidneys and in normal conditions is the protein excreted in larger amounts in human urine. It plays important roles in kidneys and urinary tract...

Golden pompano Trachinotus ovatus, a popularly cultured and commercially important marine fish worldwide, has been recognized as a promising candidate for mariculture. However, outbreaks of infectious bacterial or viral diseases and environmental deterioration have led to great economic losses in T. ovatus aquaculture recently. In our research, we established a new mid-kidney cell line, designated as TOK, from golden pompano, T. ovatus. The optimized growth temperature and working concentration of fetal bovine serum (FBS) were 28°C and 10-20%, respectively...

3-Mercaptopyruvate sulfurtransferase (MST) is one of the principal enzymes for the production of hydrogen sulfide and polysulfides in mammalians, and emerging evidence supports the physiological significance of MST. As a fundamental study of the physiology and pathobiology of MST, it is necessary to establish the tissue distribution of MST in mice. In the present study, the expression of MST in various organs of adult and fetal mice was analyzed by Western blotting and enzyme-immunohistochemistry. Moreover, the histology of MST gene-deficient mice was examined...

OBJECTIVES: Delayed motherhood is associated with an increasing number of comorbidities such as glomerulonephritis, systemic lupus erythematosus, and diabetic nephropathy. Women after renal transplant belong to the group of patients who require a highly individualized approach to treatment and diagnosis. The aim of the study was to validate the commonly used diagnostic criteria for preeclampsia which seem to be irrelevant in patients with chronic renal insufficiency. MATERIAL AND METHODS: The course of pregnancy and delivery were retrospectively analyzed in 48 renal transplant patients...

Treating infections in pregnant patients is potentially dangerous even when herbal medicines are used. Many herbal medicines, among them extracts from plants of Rhodiola genus, have antimicrobial, anti-inflammatory, and immunostimulatory properties owing to their polyphenol content; they may, however, affect fetal development due to their antiangiogenic properties. The aim of this study was to explain whether daily feeding pregnant and lactating mice with 20 mg/kg Rhodiola kirilowii aqueous (RKW) or 50% hydro-alcoholic (RKW-A) extracts, or 0...

Loss of fibroblast growth factor 23 (FGF23) causes hyperphosphatemia, extraskeletal calcifications, and early mortality; excess FGF23 causes hypophosphatemia with rickets or osteomalacia. However, FGF23 may not be important during fetal development. FGF23 deficiency (Fgf23 null) and FGF23 excess (Phex null) did not alter fetal phosphorus or skeletal parameters. In this study we further tested our hypothesis that FGF23 is not essential for fetal phosphorus regulation but becomes important after birth. Although co-receptor Klotho null adults have extremely high FGF23 concentrations, intact FGF23 was normal in Klotho null fetuses, as were fetal phosphorus and skeletal parameters, and placental and renal expression of FGF23 target genes...

Because of advancements in fetal imaging, anatomic variants of the genitourinary tract are most often discovered in the antenatal period. As such, general internists are less likely to encounter adult patients with previously undiagnosed anatomic abnormalities of the renal collecting system, such as duplicated kidneys. These abnormalities put patients at risk for urinary obstruction and recurrent infections of the urinary tract. We report the case of a 40-year-old diabetic patient with a previously undiagnosed duplex kidney who had recurrent episodes of diabetic ketoacidosis triggered by urinary tract infections...

Intussusceptive angiogenesis (IA) is required for normal embryonic vascular development. The Tie family of receptors and their ligands, the angiopoietins, play an important role in the growth or regression of blood vessels which are important not only during development but also throughout an organism's life. The presence of IA was investigated in glomerular capillaries of the fetal porcine metanephros using Mercox II resin casts. The first signs of IA were observed in stage III glomeruli. Stage IV and V glomeruli showed numerous signs of aligned pillar formation and their successive merging to delineate the vascular entities...

INTRODUCTION: The urinary tract dilation (UTD) classification system was introduced to standardize terminology in the reporting of hydronephrosis (HN), and bridge a gap between pre- and postnatal classification such as the Society for Fetal Urology (SFU) grading system. Herein we compare the intra/inter-rater reliability of both grading systems. MATERIALS AND METHODS: SFU (I-IV) and UTD (I-III) grades were independently assigned by 13 raters (9 pediatric urology staff, 2 nephrologists, 2 radiologists), twice, 3 weeks apart, to 50 sagittal postnatal ultrasonographic views of hydronephrotic kidneys...

Kidney transporters are involved in the secretion and reabsorption of endogenous and exogenous molecules. Numerous factors may influence their expression and affect drug disposition, efficacy and toxicity. The present study aimed to examine the development‑ and age‑associated variations in primary renal transporters in rats, including 6 uptake transporters: Organic anion transporter (OAT) 1 and 3, organic cation transporter (OCT) 1, 2 and 3 and organic anion‑transporting polypeptide (OATP) 4C1, and 6 efflux transporters: Multidrug resistance protein 1 (MDR1), breast cancer resistance protein (BCRP), multidrug resistance‑associated protein (MRP) 2 and 4, and multidrug and toxin extrusion protein (MATE) 1 and 2‑K...

GLI-similar 3 (GLIS3), a member of the Krüppel-like zinc finger protein subfamily, is predominantly expressed in the pancreas, thyroid, and kidney. Glis3 mRNA can be initially detected in mouse pancreas at embryonic day 11.5 and is largely restricted to β cells, pancreatic polypeptide-expressing cells, as well as ductal cells at later stage of pancreas development. Mutations in GLIS3 cause a neonatal diabetes syndrome, characterized by neonatal diabetes, congenital hypothyroidism, and polycystic kidney. Importantly, genome-wide association studies showed that variations of GLIS3 are strongly associated with both type 1 diabetes (T1D) and type 2 diabetes (T2D) in multiple populations...
