Fadel, F. I., D. M. Salah, M. A. A. Mawla, E. Galal, and S. Sayed, "Assessment of volume status of pediatric hemodialysis patients.", Pediatric nephrology (Berlin, Germany), 2024. Abstract

BACKGROUND: Accurate volume status assessment and dry weight achievement are the most challenging goals for a nephrologist. We aimed to evaluate the role of ultrasonographic parameters including lung ultrasound and inferior vena cava (IVC) measurements as practical methods of volume status assessment in children on hemodialysis by comparing them with established techniques, such as clinical evaluation and bioimpedance spectroscopy.

METHODS: A prospective cross-sectional study compared pre- and post-dialysis volume status using bioimpedance spectroscopy (BIS) parameters and clinical data with ultrasonographic lung B-lines and IVC parameters in children on regular hemodialysis.

RESULTS: A total 60 children (mean age 9.4 ± 2.8 years) were enrolled. Twenty patients (33.3%) were clinically overloaded to varying degrees (17 patients had mild to moderate signs of fluid overload and 3 patients had moderate to severe signs of fluid overload). All other patients (66.7%) were clinically euvolemic. Sonographic parameters were significantly lower post-dialysis than pre-dialysis, including lung B-line count and IVC diameter. IVC collapsibility index mean was significantly higher post-dialysis than pre-dialysis. There was a significant correlation between the lung B-line count, IVC parameters, and BIS-measured overhydration both before and after hemodialysis. Nine patients had ≥ 8 B-lines post-dialysis, only three of them were hypertensive.

CONCLUSIONS: Clinical criteria alone are not specific for determining accurate fluid status in pediatric hemodialysis patients. Lung B-line score, IVC parameters, and BIS may be complementary to each other and to clinical data. Lung B-lines outperform IVC measurements and BIS in subclinical volume overload detection in pediatric hemodialysis patients.

BACKGROUND: Patients with Type 2 diabetes mellitus (T2DM) have decreased bone health. We aimed to investigate serum levels of bone turnover markers (BTMs) (markers of bone formation and bone resorption) and bone mineral density (BMD) at three sites (lumber, neck femur, and total femur) in middle-aged men with type 2 diabetes and to analyze the relationship between them. Also to evaluate serum osteoglycin as a novel marker and its relation to BTMs, BMD, and diabetic status.

METHODS: We recruited seventy-eight patients with T2DM and thirteen non-diabetic, male volunteers as a control group. BMD was measured using a DEXA scan. BTMs (carboxy-terminal crosslinking telopeptide of type 1 collagen [CTX] and procollagen type 1 N propeptide [P1NP]), osteoglycin, PTH, and vitamin D were estimated. Data was compared among subjects and statistical analysis was performed.

RESULTS: Most of the patients were having normal BMD with no significant difference between patients and the controls. BTMs and osteoglycin were significantly higher and vitamin D was significantly lower in the diabetic patients. Serum osteoglycin was positively correlated with DEXA Neck Femur (r = 0.233; p-value < 0.05).

CONCLUSION: Body mass index and Serum osteoglycin have a significant positive effect on BMD. Both markers of bone formation and bone resorption were increased indicating a state of increased bone turnover in T2DM.

Abstract Background and Aim: Helicobacter pylori {CagA} gene is a major virulence factor that undergoes tyrosine phosphorylation in a region holding differing numbers of repeat sequences ({EPIYAs}) resulting in modulation of the inflammatory response. The aim of this cross-sectional study is to determine the correlation between {CagA} {EPIYA} motifs with diverse gastroduodenal outcomes. Methods: Gastric biopsies were collected from 54 Egyptian patients (11 patients with {PUD} and 43 chronic non atrophic gastritis). Molecular detection of H. pylori, {CagA} gene with determination of the {EPIYA} motifs in {CagA} positive cases were done. Results: Out of the 54 H. pylori positive cases, {CagA} gene was detected in 31 patients. {EPIYA}-{ABC} was the most presented pattern in 22 cases (71 %) and the least common pattern was {EPIYA}-{ABCCC}, which was positive only in one case (3.2%). Both {EPIYA}-{AB} and {EPIYA}-{ABCC} were presented in 4 cases for each (12.9% for each). Conclusion: There was a significant statistical correlation between the presence of {CagA} gene and both {PUD} and {GU}. Furthermore, the structure of the variable region of the {CagA} gene in Egyptian strains was Western type with a variable number of {EPIYA}‑C.

The intricate pathogenesis of the hepatitis B virus (HBV) and its progression to hepatocellular carcinoma (HCC) have not yet been fully elucidated. H19 is one of the earliest imprinted long noncoding RNAs (lncRNAs) associated with liver pathobiology. This study investigated the association of H19 single nucleotide polymorphisms (SNPs) rs2839698 C/T and rs217727 C/T with HBV and HBV-related HCC and their correlation with H19 expression level. A total of 230 subjects were enrolled in this study including 100 HBV-infected patients, 30 HBV-related HCC patients, and 100 apparently healthy controls. TaqMan genotyping human assays were utilized to assess allelic discrimination for H19 SNPs. H19 expression was assessed using quantitative real-time polymerase chain reaction (qRT-PCR). Our findings showed that H19 rs2839698 was linked to a higher incidence of HBV infection and HBV-related HCC. Individuals who bear the CT genotype of rs2839698 were more susceptible to HBV infection (OR = 3.05; 95% CI 1.714-5.457; p < 0.001). Those harboring the TT genotype were more prone to develop HCC (OR = 2.625; 95% CI 1.037-6.64; p = 0.038). Our data revealed that rs2839698 could function as a promising predictor of HCC risk. Furthermore, H19 was significantly downregulated in HBV (p < 0.01) and HCC (p < 0.01) patients versus the control group. Significant upregulation of H19 in HCC patients with cirrhosis (p < 0.001) was detected. Altogether, this is considered the first prospective case-control study to address the implication of the genetic variations of H19 SNPs in HBV and HBV-related HCC in Egyptian patients.

Mohamed, S. A., N. R. Kamel, A. E. Fouda, R. E. El Hawary, and M. A. Abdelmegeid, "Association of low vitamin D level and full-term early-onset neonatal sepsis; a case-control study.", Italian journal of pediatrics, vol. 50, issue 1, pp. 101, 2024. Abstract

BACKGROUND: Sepsis is one of the main causes of death in newborns worldwide. Vitamin D levels during fetal and neonatal periods have a significant role in the development of the immunological system. The study aims to evaluate the association between vitamin D levels and the risk of early-onset neonatal sepsis in full-term neonates in a developing country.

METHODS: This case-control study was conducted at the Neonatal Intensive Care Units (NICUs) of Kasr Alainy Hospital, Cairo, Egypt. The study was composed of two groups; the sepsis group involved full-term neonates appropriate for gestational age with sepsis-related clinical signs. The control group included newborns with no signs of clinical/laboratory infection within 72 h of life. Blood samples were collected on admission during the first three days of life in both groups for the measurement of 25-hydroxyvitamin D levels, Complete Blood Count (CBC), C reactive protein (CRP), and blood culture.

RESULTS: Forty-five newborns with clinical and laboratory findings of early-onset neonatal sepsis within 72 h of life were enrolled, and the control group included forty-five newborns with no evidence of sepsis. Vitamin D levels in the sepsis group were significantly lower than in the control group. Apgar score at the first minute was significantly lower in the sepsis group. 57.8% of neonates with sepsis had positive blood cultures. There was a statistical difference between deficient, insufficient, and sufficient vitamin D levels regarding the duration of the NICU stay, which was longer in neonates with deficient vitamin D levels. CRP was significantly higher in neonates with deficient vitamin D levels. The area under the receiver operating characteristic curve for serum vitamin D in the prediction of neonatal sepsis was 0.76 at a cutoff < 19.7(ng/ml).

CONCLUSION: In the current study, full-term newborns with EOS had considerably lower vitamin D levels than healthy controls. Through appropriate vitamin supplementation of the mothers during pregnancy, it could be possible to ensure adequate vitamin D levels for newborns. This may contribute to the reduction of the risk of EOS, together with the other well-known preventive measures (i.e. breastfeeding and intrapartum antibiotic prophylaxis).

Abd Elaleem, W. S., H. R. ghaiad, M. A. Abdelmawla, and A. A. Shaheen, "Attenuation of p38 MAPK/NF-κB/TRPV1/CGRP is involved in the antinociceptive effect of hesperidin methyl chalcone and taxifolin in paclitaxel-induced peripheral neuropathy.", BioFactors (Oxford, England), 2024. Abstract

Paclitaxel (PTX)-induced peripheral neuropathy (PIPN) is a disabling side effect of PTX, which adversely affects the life quality of cancer patients. Flavonoids such as hesperidin methyl chalcone (HMC) and taxifolin (TAX) can alleviate neuropathic pain via their anti-inflammatory, antioxidant, neuroprotective, and antinociceptive properties. The current study aimed to assess the efficacy of HMC and TAX in preventing PIPN individually or in combination. Pretreatment with HMC and TAX mitigated PTX-induced mechanical allodynia and hyperalgesia, cold allodynia, and thermal hyperalgesia as well as restore the normal histological architecture. Remarkably, neuropathic pain was relieved by suppression of nerve growth factor (NGF), p38 mitogen-activated protein kinase (p38 MAPK), and transient receptor potential vanilloid type-1 (TRPV1), which ultimately lead to reduced calcitonin gene-related peptide (CGRP). Furthermore, both HMC or TAX enhanced nuclear factor erythroid 2-related factor 2 (Nrf2), leading to elevated glutathione (GSH) and total antioxidant capacity (TAC) along with lowered malondialdehyde (MDA), which in turn, downregulated nuclear factor kappa B P65 (NF-κB P65) and its phosphorylated form and eventually reduced tumor necrosis factor alpha (TNF-α) and interleukin-1 beta (IL-1β) then lowered the apoptotic indices. Promisingly, the combination of both agents was superior to each drug alone through targeting more diverse signaling pathways and achieving synergistic and comprehensive therapeutic effects. In conclusion, pretreatment with HMC and TAX separately or in combination alleviated PIPN via modulating NGF/p38 MAPK/NF-κB P65/TRPV1/CGRP pathway.

In the current study, voriconazole (VCZ) augmented glycerosomes were optimized for topical otomycosis management according to a 23 factorial design, employing a thin film hydration method. By optimizing Glycerol volume, limonene: VCZ ratio and Span® 60: soybean phosphatidyl choline (PC) ratio, glycerosomes with maximum percentage entrapment efficiency (%EE) and zeta potential (ZP) and minimum vesicle size (VS) and polydispersity index (PDI) were to be obtained. An optimal augmented glycerosomal formula (OAG) that contained 10 mg VCZ, 150 mg PC, and 3 mL glycerol, comprising 2.5: and 0.92:1 ratios of the latter two independent variables, was proposed via numerical optimization. OAG exhibited high %EE and ZP values and acceptable low values for VS and PDI (84.3 ± 2.0 %, −38.8 ± 1.8 mV, 191.0 ± 1.1 nm, and 0.192 ± 0.01, respectively). Extensive in vitro testing of OAG revealed the entrapment of VCZ within OAG, biphasic in vitro release profile, stability for up to 3 months at 2–8 °C and spherical morphology of OAG with VS like that obtained via zetasizer. OAG demonstrated higher permeated amounts of VCZ and flux values than VCZ suspension, leading to an enhancement ratio of 2.56 in the ex vivo permeation study. The deeper penetration ability of OAG demonstrated by Confocal Laser Scanning Microscopy and its superior in vitro antifungal activity confirmed the validity of the ex vivo study. Also, the histopathological study confirmed the safety of OAG for topical use, suggesting that VCZ OAG was a promising topical antimycotic formula.
