RESUMO

BACKGROUND/AIMS: Two earthquakes on February 6th, 2023 destroyed ten cities in Türkiye. We report our experience with pediatric victims during these catastrophes, with a focus on crush syndrome related-acute kidney injury (Crush-AKI) and death. METHOD: A web-based software was prepared. Patient demographics, time under rubble (TUR), admission laboratory data, dialysis, and kidney and overall outcomes were asked. RESULTS: 903 injured children (median age: 11.62 years) were evaluated. Mean TUR was 13 h (Interquartile range-IQR: 32.5), max 240 h). 31 of 32 patients with a TUR of >120 h survived. The patient who rescued after ten days survived.Two-thirds of the patients were given 50 mEq/L sodium-bicarbonate in 0.45% sodium-chloride solution on admission day. 58% of patients were given intravenous fluid (IVF) at a volume of 2000-3000 mL/m2 body surface area (BSA), 40% of 3000-4000 mL/m2 BSA, and only 2% of >4000 mL/m2 BSA. 425 patients had surgeries, 48 suffered from major bleeding. Amputations were recorded in 96 patients. Eighty-two and 66 patients required ventilator and inotropic support, respectively.Crush-AKI developed in 314 patients (36% of all patients). 189 patients were dialyzed. Age > 15 years, creatine phosphokinase (CK)≥20 950 U/L, TUR≥10 h, and the first-day IVF volume < 3000-4000 mL/m2 BSA were associated with Crush-AKI development. 22 deaths were recorded, 20 of 22 occurred in patients with Crush-AKI and within the first 4 days of admission. All patients admitted after 7 days survived. CONCLUSIONS: This is the most extensive pediatric kidney disaster data after an earthquake. Serum CK level was significantly associated with Crush-AKI at the levels of >20 950 U/L, but not with death. Adolescent age and initial IVF of less than 3000-4000 mL/m2 BSA were also asscoiated with Crush-AKI. Given that mildly injured victims can survive longer periods in the disaster field, we suggest uninterrupted rescue activity for at least 10 days.

RESUMO

Quercetin (QUE) belonging to the flavonoid class is a common phytochemical present in the daily diet of some individuals. Quercetin is an important source of free radical scavengers. This property makes this flavonoid a reliable antioxidant with the following properties: anti-inflammatory, anti-diabetic, antimicrobial and anti-carcinogenic. Sodium butyrate (NaBu) acts as a histone deacetylase inhibitor (HDACi) and is known to regulate apoptosis in cancer cells. Combining natural flavonoids such as QUE with different substances may synergistically enhance their anti-carcinogenic capacity. Thus, the aim of this study was to examine the combined treatment effects of QUE and NaBu in hormone-sensitive breast cancer cells in vitro. MCF-7 breast cancer cells were treated with QUE alone, NaBu alone, as well as QUE and NaBu combined to determine the following: cell proliferation, levels of protein annexin A5 (ANXA5) and reactive oxygen species (ROS), mRNA protein expression, as well as cell and nuclear morphology. Data demonstrated that either QUE or NaBu alone inhibited cell proliferation, and reduced levels protein ANXA5, ROS and mRNA protein expression, The combination of QUE and NaBu produced a significant synergistic inhibitory effect compared to treatment groups of QUE or NaBu alone. In conclusion, our findings showed that the combination treatment of QUE and NaBu may constitute a promising therapeutic approach to breast cancer treatment but this needs further molecular and in vivo investigations.

RESUMO

Developing new drugs from natural products is important for therapeutic effects to minimise tissue toxicity of drugs used in cancer treatment. Eisenia foetida is a worm with a double transport system consisting of coelomic fluid (ECF) that can be used as alternative medicine. It is important to eliminate or reduce the high cytotoxicity of sodium butyrate (NaBu), a chemotherapeutic agent used in breast cancer treatment, for both neoplastic and normal cells. We aimed to evaluate the effect of ECF on the oxidative toxicity induced by NaBu in MCF-7 cells, changes in ROS production levels and expression of cell death and ROS-related genes. It was determined that the expression levels of Bax and Bcl-2 genes remained unchanged, while the amount of ROS decreased significantly in MCF-7 cells exposed to NaBu with ECF. Thus, ECF may be a potential therapeutic molecule with fewer side effects in cancer treatment in the future.

RESUMO

The aim of this study was to investigate the effect of stress management training on the perceived stress, anxiety and hopelessness levels of women with high-risk pregnancy. The sample of this experimental study consisted of 206 high-risk pregnant women (intervention = 103; control = 103). Data were collected using a Personal Information Form, the Perceived Stress Scale, the Beck Hopelessness Scale and the State-Trait Anxiety Inventory. In the second follow-up after the training, there was a statistically significant difference amongst the Perceived Stress Scale, Beck Hopelessness Scale and State-Trait Anxiety Inventory mean scores in the intervention and control groups (p < .05). Perceived stress scores of the control group who did not receive training during discharge increased. The state and trait anxiety scores and hopelessness scores of the intervention group received training decreased compared with the control group.IMPACT STATEMENTWhat is already known on this subject? Mental problems such as anxiety and stress are more common in high-risk pregnancies compared with healthy pregnancies.What do the results of this study add? After the training 51.4% of women in the intervention group, 75.7% of women in the control group had stress. The state and trait anxiety and hopelessness scores of the intervention group having training decreased compared to the control group.What are the implications of these findings for clinical practice and/or further research? Health professionals should provide stress management training in high-risk pregnant women to reducing perceived stress, anxiety and hopelessness levels.

RESUMO

AIMS: Severe reduction in nephron numbers that are characteristic of renal hypodysplasia (RHD) are one of the cause of childhood chronic kidney disease (CKD). Glomerular hyperfiltration, glomerular hypertrophy, progressive glomerular scarring, and interstitial fibrosis due to reduced nephron number are risk factors for CKD. In recent years, studies on specific markers for early diagnosis of renal failure and mortality have been carried out. The objectives of this study were to identify serum and urinary endocan levels that are expressed in glomerular endothelial cells and tubular epithelial cells in RHD. MATERIALS AND METHODS: 29 children with RHD were compared to 26 healthy controls in terms of serum and urinary endocan levels. RESULTS: The mean serum endocan level in the RHD group and the control group was 700.72 ± 323.19 and 426.86 ± 233.14 pg/mL, respectively. The mean serum endocan level was significantly higher (p = 0.003) in the RHD group. The mean urinary endocan level in the RHD group was 63.62 ± 92.46 pg/mL, and in the control group it was 80.26 ± 142.49 pg/mL. The mean urinary endocan level did not change between groups (p = 0.95). There was also a significant correlation between serum endocan level and uric acid level in the study group (r = 0.325, p = 0.028). CONCLUSION: To our knowledge, this was the first study that evaluated serum and urinary endocan levels in children with RHD. Although serum endocan level was found to be significantly higher in patients with RHD, further studies are needed to validate whether endocan could serve as a marker of poor renal prognosis in RHD.

RESUMO

Neurofibromatosis type 1 (NF1) is an autosomal-dominant neurocutaneous syndrome affecting various parts of the body, including the renovascular and urinary systems. We evaluated the renovascular, urinary, glomerular, and tubular functions of children with NF1. We compared blood pressures, urinary findings, and renal glomerular and tubular functions in children with NF1 with those of a healthy age- and gender-matched control group. We evaluated 46 NF1 patients and 33 healthy controls. The mean ages of the NF1 group (female/male: 20/26) and the control group (female/male: 15/18) were 10.1 ± 4.6 and 10.6 ± 4.3 years respectively. Six NF1 patients were hypertensive. The mean blood pressures of the NF1 group were significantly higher than those of the control group. Renal artery stenosis was detected in one NF1 patient. Urinary tract anomalies were evident in 21.7% of NF1 but only 9% of control subjects. The mean estimated glomerular filtration rate (eGFR) of the NF1 group was significantly lower than that of the control group. Six NF1 patients evidenced eGFRs < 90 mL/min. In the NF1 group, tubular phosphorus reabsorption was significantly lower and uric acid excretion significantly higher than in the control group.Conclusion: Hypertension, urinary tract anomalies, and impaired renal function were more common in NF1 patients than healthy controls. Regular blood pressure measurements and evaluation of urinary tract and kidney function are essential for NF1 patients. What is Known: • NF1 is most commonly associated with systemic hypertension due to renal artery vasculopathy and the development of a pheochromocytoma. • Hydronephrosis and bladder involvement have been documented in NF1. What is New: • Renal glomerular and tubular functions may be affected in NF1.

RESUMO

Bartter syndrome with sensorineural deafness (Bartter syndrome type 4) is an autosomal recessive disorder characterized with polyhydramniosis, premature birth, massive polyuria, renal salt-wasting, hypokalemic metabolic alkalosis, normotensive hyperreninemic hyperaldosteronism, and hearing loss. Homozygous mutations in BSND, CLCNKA, and CLCNKB mutations cause the disorder. Here we report a 3-year-old boy who had not been evaluated and investigated before cochlear implantation. Hypokalemia was detected during the routine laboratory workup before surgery. Further analyses revealed metabolic alkalosis with high renin and aldosterone levels. Hypokalemia improved with oral potassium chloride supplementation. Genetic tests revealed a homozygous c.139G>A (pG47R) mutation in BSND gene, and both parents were heterozygous for the same mutation. We want to emphasize the importance of evaluating hearing loss in children, since some of the genetic syndromes may cause life threatening abnormalities.

RESUMO

Oncogene-induced senescence is an anti-proliferative stress response program that acts as a fail-safe mechanism to limit oncogenic transformation and is regulated by the retinoblastoma protein (RB) and p53 tumor suppressor pathways. We identify the atypical E2F family member E2F7 as the only E2F transcription factor potently up-regulated during oncogene-induced senescence, a setting where it acts in response to p53 as a direct transcriptional target. Once induced, E2F7 binds and represses a series of E2F target genes and cooperates with RB to efficiently promote cell cycle arrest and limit oncogenic transformation. Disruption of RB triggers a further increase in E2F7, which induces a second cell cycle checkpoint that prevents unconstrained cell division despite aberrant DNA replication. Mechanistically, E2F7 compensates for the loss of RB in repressing mitotic E2F target genes. Together, our results identify a causal role for E2F7 in cellular senescence and uncover a novel link between the RB and p53 pathways.
