Enalapril and Acute Kidney Injury in a Hypertensive Premature Newborn - Should It Be Used or Not?

1 month ago
Extremely low birth weight infants (birth weight ≤1000 g) have a significantly lower nephron number. The glomerular filtration rate (GFR) is usually sufficient under normal conditions but is unable to meet the needs during stress, which results in acute kidney injury (AKI). We describe the case of an extremely low birth weight infant (970 g) with a gestational age of 27 weeks (immature preterm) who was mechanically ventilated because of hyaline membrane disease. AKI with anuria and a rise in...

Auto-inhibitory intramolecular S5/S6 interaction in the TRPV6 channel regulates breast cancer cell migration and invasion

1 month ago
TRPV6, a Ca-selective channel, is abundantly expressed in the placenta, intestine, kidney and bone marrow. TRPV6 is vital to Ca homeostasis and its defective expression or function is linked to transient neonatal hyperparathyroidism, Lowe syndrome/Dent disease, renal stone, osteoporosis and cancers. The fact that the molecular mechanism underlying the function and regulation of TRPV6 is still not well understood hampers, in particular, the understanding of how TRPV6 contributes to breast cancer...

Awareness of obstetricians for long-term risks in women with a history of preeclampsia or HELLP syndrome

1 month 1 week ago
CONCLUSIONS: We were able to show that counselling concerning the risk of long-term cardiovascular disease and risk of recurrence after a pregnancy complicated by preeclampsia or HELLP syndrome has been established in obstetric departments in public hospitals. Regarding the evaluation of underlying chronic diseases such as thrombophilia or renal disease, as well as counselling on the future risk of renal disease is still improvable according to our data. Further evaluation of follow-up care...

Advances in Kidney Replacement Therapy in Infants

1 month 1 week ago
Acute kidney injury continues to be a highly occurring disease in the intensive care unit, specifically affecting up to a third of critically ill neonates as per various studies. Although first-line treatments of acute kidney injury are noninvasive, kidney replacement therapy (KRT) is indicated when conservative management modes fail. There are various modalities of KRT which can be used for neonatal populations, including peritoneal dialysis, hemodialysis, and continuous KRT. However, these KRT...

Ultrasonographic evaluation of the children with candiduria for the fungal ball: Is It necessary?

1 month 1 week ago
CONCLUSIONS: Despite the low incidence of fungal balls reported, considering the high consequences of missing a fungal ball and elimination of it, a non-invasive method such as the renal bladder USG is still necessary for detection of fungal ball especially. More prospective studies are required for high risk groups to establish the diagnostic value of renal USG.

Prenatal Diagnosis of Fetal Congenital Mesoblastic Nephroma and Neonatal Follow-up

1 month 2 weeks ago
We describe a case of fetal congenital mesoblastic nephroma (CMN) who was diagnosed with ultrasound at 32 weeks of gestation; after delivery, the neonate received left radical nephrectomy, and pathology report confirmed the diagnosis. All cross-sectional imaging studies, such as ultrasonography, computed tomography (CT) scanning, and magnetic resonance imaging, may help to define the organ of origin and the relationship to the ipsilateral kidney. To our knowledge, this is the first case of fetal...

An alternate covalent form of platelet αIIbβ3 integrin that resides in focal adhesions and has altered function

1 month 2 weeks ago
The αIIbβ3 integrin receptor coordinates platelet adhesion, activation and mechanosensing in thrombosis and haemostasis. Using differential cysteine alkylation and mass spectrometry, we have identified a disulfide bond in the αIIb subunit linking cysteines 490 and 545 that is missing in about one in three integrin molecules on the resting and activated human platelet surface. This alternate covalent form of αIIbβ3 is pre-determined as it is also produced by human megakaryoblasts and baby hamster...

Phenotype of a transient neonatal diabetes point mutation (SUR1-R1183W) in mice

1 month 2 weeks ago
Background: The K (ATP) channel plays a key role in glucose homeostasis by coupling metabolically generated changes in ATP to insulin secretion from pancreatic beta-cells. Gain-of-function mutations in either the pore-forming (Kir6.2) or regulatory (SUR1) subunit of this channel are a common cause of transient neonatal diabetes mellitus (TNDM), in which diabetes presents shortly after birth but remits within the first few years of life, only to return in later life. The reasons behind this time...

Pregnant woman with renal cancer treated with simultaneous section and partial nephrectomy

1 month 2 weeks ago
This is a case report of a 43-year-old pregnant woman, who in 26+0 was referred to a department of urology on suspicion of a kidney tumor. A CT scan of chest and abdomen showed a 7 cm tumor in the right kidney without signs of metastases. Biopsy revealed a clear cell renal cell carcinoma. The patient was treated in week 32+0 by a joint venture between a department of urology and a department of obstetrics with a midline incision caesarean followed by a right-sided open partial nephrectomy. The...

In vitro cytotoxic potential of <em>Solanum nigrum</em> against human cancer cell lines

1 month 2 weeks ago
Plants have natural products which use to possess antiproliferative potential against many cancers. In the present study, six isolated fractions (ethyl acetate, petroleum ether, chloroform, n-butanol, ethanol and aqueous) from Solanum nigrum were evaluated for their cytotoxic effect on different cell lines. Hepatic carcinoma cell line (HepG2), cervical cancer cell line (HeLa) and baby hamster kidney (BHK) used as normal non-cancerous cells were evaluated for cytotoxicity against isolated...

Potential Heart, Liver, and Kidney Donation after Circulatory Determination of Death in a Neonatal Intensive Care Unit

1 month 2 weeks ago
CONCLUSIONS: While uncommon, we identified potential DCD organ donors in the NICU population for kidney, heart, and liver transplants. The substantial variability in the number of potential donors depending on the selected eligibility criteria emphasizes the need for a standardized definition adapted to local capacities.

Maternal, foetal and child consequences of immunosuppressive drugs during pregnancy in women with organ transplant: a review

1 month 3 weeks ago
Although pregnancy remains exceptional in women after heart, liver or lung transplant, obstetricians and nephrologists are regularly confronted with pregnancy in renal transplant recipients. National and international registries have described the epidemiology of maternal, foetal and neonatal complications, and transplantation societies have published recommendations on the monitoring of these high-risk pregnancies. In this review, we summarize the existing data on maternal and foetal...

Nephrotoxicity in Neonates

1 month 3 weeks ago
Acute kidney injury (AKI) is classified based on prerenal, intrinsic, and postrenal causes. In the newborn, AKI can occur after an insult during the prenatal, perinatal, or postnatal period. AKI is usually an underrecognized condition and its true incidence is unknown. AKI may result from the administration of a number of different nephrotoxic medications, which are often used concurrently in critically ill neonates, exponentially increasing the risk of renal injury. Drug toxicity may also...

Hematuria in a 3-month-old filly with an internal umbilical abscess and internal iliac artery aneurysm

1 month 3 weeks ago
A 3-month-old foal with a history of acute hematuria was evaluated. Hydronephrosis and hydroureter were visualized upon renal ultrasonography of the left kidney. Cystoscopy identified a blood clot occluding the left ureter. Computed tomography (CT) revealed a large retroperitoneal abscess at the level of the aortic bifurcation and a left internal iliac aneurysm. Due to the severity of the lesions and the poor prognosis, the filly was euthanized and the clinical findings were confirmed by...

Expression of specific signaling components related to muscle protein turnover and of branched-chain amino acid catabolic enzymes in muscle and adipose tissue of preterm and term calves

1 month 3 weeks ago
Postnatal metabolism depends on maturation of key metabolic pathways around birth. In this regard, endogenous glucose production is impaired in calves born preterm. Concerning protein metabolism, the rates of protein turnover are greater during the neonatal period than at any other period of postnatal life. The mammalian target of rapamycin (mTOR) and the ubiquitin-proteasome system (UPS) are considered as the major regulators of cellular protein turnover. The objectives of this study were to...
