Survival characteristics of Wilms Tumor, a reference developed from a longitudinal cohort study.

BACKGROUND: Wilms tumor (WT) survival has been affected by the evolution in clinical and biological prognostic factors. Significant differences in survival rates indicate the need for further efforts to reduce these disparities. This study aims to evaluate the clinicopathological data impact on survival among patients after Wilm's diagnosis. METHODS: The study utilized the SEERStat Database to identify Wilms tumor patients, applying SEERStat software version 8.3.9.2 for data extraction. Selection criteria involved specific codes based on the International Classification of Diseases for Oncology (ICDO-3), excluding cases with unknown SEER stage, incomplete survival data, unknown size, or lymph node status. Statistical analyses, including Kaplan-Meier estimates and Cox regression models, were conducted using R software version 3.5. Standardized mortality ratios (SMR) were computed with SEER*Stat software, and relative and conditional survival analyses were performed to evaluate long-term survival outcomes. RESULTS: Of 2273 patients diagnosed with Wilms tumor, (1219 patients, 53.6% were females with an average age group of 3-8 years (50.2%). The overall mean survival after five years of diagnosis was 93.6% (2.6-94.7), and the overall mean survival rate was 92.5% (91.3-93.8) after ten years of diagnosis. Renal cancers were identified as the leading cause of death (77.3%), followed by nonrenal cancers (11%) and noncancer causes (11%). Additionally, robust relative survival rates of 98.10%, 92.80%, and 91.3% at one, five, and ten years, respectively, were observed, with corresponding five-year conditional survival rates indicating an increasing likelihood of survival with each additional year post-diagnosis. Univariate Cox regression identified significant prognostic factors: superior CSS for patients below 3 years (cHR 0.48) and poorer CSS for those older than 15 years (cHR 2.72), distant spread (cHR 10.24), regional spread (cHR 3.09), and unknown stage (cHR 4.97). In the multivariate model, age was not a significant predictor, but distant spread (aHR 9.22), regional spread (aHR 2.84), and unknown stage (aHR 4.98) were associated with worse CSS compared to localized tumors. CONCLUSION: This study delving into WT survival dynamics reveals a multifaceted landscape influenced by clinicopathological variables. This comprehensive understanding emphasizes the imperative for ongoing research and personalized interventions to refine survival rates and address nuanced challenges across age, stage, and tumor spread in WT patients.

Neonatal Microbiome: Is it Still Beneficial?

The neonatal microbiome includes all the microorganisms living within or on the surface of the newborn, as well as their genes (i.e., bacteria, fungi, and viruses), which are composed mainly of bacteria. The majority of these microorganisms reside in the gastrointestinal tract (GIT), which is known as the gut microbiome. They include trillions of microbes, which exceed the total number of neonate cells. In this study, we have examined factors affecting neonatal microbiome colonization, various phyla of the microbiome in neonates, and their characteristics. In addition, we have discussed symbiosis and dysbiosis, precipitating diseases, breast milk's role in the neonatal gut microbiome, prebiotics, probiotics, postbiotics, and synbiotics, as well as the airway or respiratory microbiome, and the main role of the neonatal microbiome. We have also discussed neonatal mycobiome and neonatal virome, as well as the research done on the neonatal microbiome.

Effect of hyperbaric oxygen therapy and Tomatis sound therapy in children with autism spectrum disorder.

Many therapeutic and dietary regimens have been studied for children with autism spectrum disorder (ASD) in the last three decades. We aimed to evaluate the efficacy of hyperbaric oxygen therapy (HBOT) and Tomatis sound therapy (TST) in an Egyptian cohort of children with ASD. This study was a prospective, open label, randomized interventional clinical trial. One hundred forty-six children with ASD with no previous rehabilitation therapy were enrolled in our study. Patients were randomly divided into four groups: the first group received hyperbaric oxygen therapy, the second group received Tomatis sound therapy, the third group received a combination of both modalities, and the fourth group, the control group, received no intervention. We found that the combination of Tomatis sound therapy with hyperbaric oxygen therapy had a superior effect in improving autism symptoms than each intervention alone (CARS after therapy 35.04 ± 13.38 versus 49.34 ± 17.54 before the intervention, p < 0.001). The combination of both modalities may be helpful for children with ASD. The most distinctive evidence that supports the use of combination therapy for ASD is still controversial; however, our study provides some evidence of the benefit of combination therapy for children with ASD. Future studies should use a more sophisticated research design and begin by finding a consistent baseline measure that can be used to evaluate the effects of these therapies for ASD.

Serum Galanin in Children with Autism Spectrum Disorder.

Recent studies have attempted to measure several biomarkers to understand the complex interactions of the anatomic systems that may be involved in autism spectrum disorder (ASD). In CNS, galanin takes part in a variety of pathological and physiological processes. Prior research has indicated it is involved in several neuropsychiatric disorders and has a role in inhibiting the neuronal firing and release of serotonin, norepinephrine, and acetylcholine. To date, serum galanin levels have not been investigated in the context of ASD. This study aimed, therefore, to compare the serum galanin levels of children with ASD and healthy controls and to reveal any association between galanin level and the severity of ASD, as well as other psychological and demographic parameters. Serum galanin levels were measured by radioimmunoassay in 116 children with ASD and 98 healthy children. We observed significantly increased serum concentrations of galanin in children with ASD relative to healthy children. Moreover, children with severe ASD had significantly higher galanin levels than those with less severe disease. We also confirmed significant positive correlations between galanin and psychiatric parameters in children with ASD. For the first time, we suggest a possible correlation between serum galanin and the degree of ASD severity. Increased galanin levels may play a role in the pathogenesis of ASD.
