Migration of Ventriculoperitoneal Shunt to Uterus In A Child: A Case Report

xlomafota13 shared this article with you from Inoreader Migration of Ventriculoperitoneal Shunt to Uterus In A Child: A Case Report Via leak of cerebrospinal fluid J Pediatr Adolesc Gynecol. 2021 Nov 26:S1083-3188(21)00343-0. doi: 10.1016/j.jpag.2021.11.004. Online ahead of print. ABSTRACT BACKGROUND: Ventriculo-peritoneal shunt (VPS) is usually placed inside the peritoneal cavity for cerebrospinal fluid drainage. Rarely, it can migrate to various pelvic visceral organs. Inside the pelvis, the distal end of the shunt can perforate anywhere from the uterus or adnexa to the vulva and migration through the uterus is extremely rare. CASE: A three-and-a-half-year-old girl presented with CSF leak through the vagina following uterine perforation by VPS. The diagnosis was made with an ultrasound. Her symptoms resolved following revision surgery. CONCLUSION: In a patient with a VPS in situ, presenting with a watery fluid leak through vagina, perforation of fornix or uterus must always be kept in mind. Timely diagnosis and intervention can result in the prevention of complications. PMID:34843976 | DOI:10.1016/j.jpag.2021.11.004 View on the web Inoreader. Take back control of your news feed.

Comprehensive gene cluster analysis of head and neck squamous cell carcinoma TCGA RNA‐seq data defines B cell immunity‐related genes as a robust survival predictor

xlomafota13 shared this article with you from Inoreader Comprehensive gene cluster analysis of head and neck squamous cell carcinoma TCGA RNA‐seq data defines B cell immunity‐related genes as a robust survival predictor Via Head & Neck Abstract Background The authors aimed to define novel gene expression signatures that are associated with patients' survival with head and neck squamous cell carcinoma (HNSCC). Methods TCGA RNA-seq data were used for gene expression clusters extraction from 499 tumor samples by the "EPIG" method. Tumor samples were then partitioned into lower and higher than median level groups for survival relevant analysis by Kaplan–Meier estimator. Results We found that two gene clusters (_1, _2) are favorably, while two (_3, _4) are unfavorably, associated with patients' survival with HNSCC. Notably, most genes on the top lists of cluster_2 are associated with B cells. A gene expression signature with combined genes from cluster_2 and _4 was further determined to be associated with HNSCC survival rate. Conclusion Our work strongly supported a favorable role of B cells in patients' survival with HNSCC and identified a novel coexpressed gene signature as prognostic biomarker for patients' survival with HNSCC estimation.

Geographic disparities in head and neck cancer survival

xlomafota13 shared this article with you from Inoreader Geographic disparities in head and neck cancer survival in Upstate New York 2011–2019 Via Head & Neck Abstract Purpose To examine the association between distance to care-center and urban–rural residence on 5-year overall survival (OS) from head and neck cancer (HNC). Materials and methods Five-year OS was retrospectively measured from date of initial diagnosis for patients with HNC treated at a single tertiary care center. Distances were calculated based on ZIP code of patient's residence and care center. Multilevel Weibull regression was used to adjust for confounders and identify disparities in 5-year all-cause mortality. Results A total of 670 patients included in study. Multivariable analysis revealed older age or late-stage cancer at diagnosis, and HPV negative status were associated with poorer OS. Patients residing in isolated small rural town (HR = 2.20, p = 0.015) or small rural town (HR = 2.07, p = 0.015) had lower OS. Distance to care center was not associated with OS (HR = 0.996, p = 0.11). Conclusions Greater rurality was associated with poorer OS among HNC patients in Upstate New York.

Quercetin regulates inflammation, oxidative stress, apoptosis, and mitochondrial structure and function in H9C2 cells by promoting PVT1 expression

xlomafota13 shared this article with you from Inoreader Quercetin regulates inflammation, oxidative stress, apoptosis, and mitochondrial structure and function in H9C2 cells by promoting PVT1 expression Via histochem Acta Histochem. 2021 Nov 26;123(8):151819. doi: 10.1016/j.acthis.2021.151819. Online ahead of print. ABSTRACT OBJECTIVE: To investigate the effect and potential mechanism of quercetin on inflammation, oxidative stress, apoptosis, and mitochondrial structure and function in H9C2 cells. MATERIALS AND METHODS: H9C2 cells were obtained from the Shanghai Institutes for Biological Sciences, Chinese Academy of Science, and randomly divided into six groups: control, model, PVT 1 overexpression (OV), quercetin, OV + quercetin, and NAC groups. The CCK-8 assay was performed to examine cell proliferation. Flow cytometry was used to examine cell apoptosis, cell membrane potential, and ROS levels. The expression of endothelial nitric oxide synthase (eNOS), malondialdehyde (MDA), and superoxide dismutase (SOD) was measured by ELISA and a Biochemical kit. Western blotting was used to determine the levels of p-DRP1 (s637), MFN2, NF-kB, p-NF-kB, IkB, and p-IkB. IL-6, IL-10, TNF-α, and IL-1β mRNA expression was examined by RT-PCR. Electron microscopy was used to observe the structure of mitochondria in H9C2 cells. RESULTS: MDA, p-NF-κB, p-IKB, IL-6, IL-1β, and TNF-α expression levels, and the cell apoptosis rate were significantly higher in the model group than in the control group (P < 0.05). In contrast, the cell proliferation rate and IL-10, SOD, eNOS, and ATP levels were significantly lower in the model group (P < 0.05). Moreover, MDA expression was significantly lower in the OV, quercetin, quercetin + OV, and NAC groups than in the model group (P < 0.05), while SOD, eNOS, and ATP levels were higher. The electron microscopy results showed that PVT1 overexpression or quercetin treatment could inhibit inflammation-induced mitochondrial fission and promote mitochondrial fusion. CONCLUSION: Quercetin promotes the proliferation of H9C2 cells, while inhibiting inflammation, oxidative stress, and cell apoptosis, and alleviating the structural and functional dysfunction of mitochondria. These effects are achieved by promoting PVT1 expression. PMID:34844154 | DOI:10.1016/j.acthis.2021.151819 View on the web Inoreader. Take back control of your news feed.

Heads up reconstructive microsurgery: Utilisation of the three-dimensional microscope in microvascular procedures

xlomafota13 shared this article with you from Inoreader Heads up reconstructive microsurgery: Utilisation of the three-dimensional microscope in microvascular procedures Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Nov 15:S1748-6815(21)00575-1. doi: 10.1016/j.bjps.2021.11.036. Online ahead of print. ABSTRACT BACKGROUND: Since the earliest use of microscopes in surgery, several modifications have been made to improve the ergonomics of movement and posture, increase the resolution, and expand the visual field. The three-dimensional microscopes are latest innovation in this field. Despite the wider use of 3D microscopes in other specialities, their use in the reconstructive microsurgery in the United Kingdom is still limited. Reconstructive microsurgeons are highly skilled surgeons that are trained to operate utilising the microscope for long hours. This poses an occupational risk with a specific pattern of work-related conditions. AIMS AND METHODS: We aim in this report to demonstrate our experience utilising 3D microscopes in small cohort of patients matched to a control of patients operated utilising the traditional microscopes. Patients were matched by age, comorbidities, oncologic procedures. This was complemented by a survey completed by the operating surgeons. RESULTS: Nine patients were included in each group. There was no significant difference in operative or ischemia time and no significant post-operative complications in both groups. The surgeons reported better ergonomics, improved staff engagement, and a better teaching experience when utilising the 3D microscopes compared to traditional microscopes. CONCLUSION: The utilisation of the 3D microscopes in reconstructive microsurgery has shown to provide comfort, improve ergonomics of movement and posture without significant clinical implications in this series.
