3%), bone graft infection (2.0%), and hydrocephalus (5.7%). Overall, 57 patients (18.9%) had undergone shunt implantation prior to CP. The incidence of epi-/subdural fluid collection was 19.3% in patients with VPS and 4.5% in patients without VPS, OR 5.1 (95% CI 2.1-12.4). Incidence of hygroma was higher in patients who underwent early CP. Patients with temporary shunt ligation for CP did not suffer from complications.

CP in patients with a VPS remains a high-risk procedure. Any effort to understand the pressure dynamics and to reduce factors that may trigger the formation of a large epidural space must be undertaken.

Spinal cord stimulation (SCS) is a neuromodulatory technique used to relieve chronic pain. Previous instances of malicious remote control of implantable medical devices, including insulin delivery pumps and implantable cardiac defibrillators, have been documented. Though no cases of neuromodulatory hacking have been recorded outside of the academic setting, an understanding of SCS technology and the possible consequences of manipulation is important in promoting safety.

We review the components and implantation protocol of a SCS system, the functionality and technological specifications for SCS systems in the global market based on their device manuals, and patient- and clinician-specific adjustable factors. Furthermore, we assess documented instances of implantable medical device hacking and speculate on the potential harms of targeting SCS systems.

SCS systems from Abbott Laboratories, Boston Scientific, Medtronic, and Nevro have unique functionality and technological specifications. Six parameters in device control can potentially be targeted and elicit various harms, including loss of therapeutic effect, accelerated battery drainage, paresthesia in unintended locations, muscle weakness or dysfunction, tissue burn, and electrical shock.

Based on the history of implantable medical device hacking, SCS systems may also be susceptible to manipulation. As the prevalence of SCS use increases and SCS systems continuously evolve in the direction of wireless control and compatibility with mobile devices, appropriate measures should be taken by manufacturers and governmental agencies to ensure safety.

The aim of this study was to evaluate the potential role of platelet-rich fibrin (PRF) application on the pharyngeal repair on decreasing the incidence of pharyngocutaneous fistula (PCF) after total laryngectomy.

This randomized controlled clinical trial was conducted on 67 patients with advanced laryngeal carcinoma who underwent total laryngectomy, over 2years in the Otorhinolaryngology Department, Mansoura University Hospitals, Egypt. Patients were randomly assigned into two groups PRF group (n = 35) and control group (n = 32). Risk factors for development of PCF as well as the incidence of PCF were studied in both groups.

There was no statistically significant difference between groups regarding demographic data, medical comorbidities, basal hemoglobin and albumin levels, data related to the tumor (location, grade and TNM staging) and surgical details (preoperative tracheotomy and neck dissection). However, regarding the incidence of PCF, there was a statistically significant difference between groups as shown in Table 2. PCF was detected in 2/35 patients (5.7%) in the PRF group and in 10/32 patients (31.3%) in the control group (p = 0.004).

PRF application on the pharyngeal repair after total laryngectomy enhances the healing process and consequently decreases the incidence of PCF.

Adenocarcinoma of the salivary glands is of low incidence and a broad range of histopathological subtypes. find more Cancer stem cell markers (CSC) might serve as novel prognostic parameters. To date, only a few studies examined the expression of CSC in adenocarcinoma of the salivary glands with diverging results. To further investigate the reliability in terms of prognostic value, a histopathological analysis of CSCs on a cohort of patients with adenocarcinomas of the major salivary glands was performed.

Tumor samples of 40 consecutive patients with adenocarcinoma of the major salivary gland treated with curative intend at one tertiary center were stained with the CSCs ALDH1, BMI-1, CD44, Nanog, and SOX2. Expression of these markers was correlated with clinicopathological parameters and survival estimates.

Correlation of high expression of ALDH1 with higher grading (p < 0.001) and high expression of CD44 with the localization of the neoplasm (p = 0.05), larger tumor size (p = 0.006), positive pN-category (p =inoma of the salivary glands.

Plant growth is greatly inhibited in tightly sealed Petri dishes for lack of CO

. Bacteria which co-cultured with plant can produce CO

to promote plant growth in sealed systems. Bacteria produce a wide variety of volatiles, some of which can support and others can damage plant growth. It is a controversial issue whether CO

or other bacterial volatile compounds promote plant growth in sealed systems. CO

is critical for photosynthesis. Here, we show that CO

is a key constituent of the plant growth-promoting volatiles generated by bacteria in a sealed system. We revealed that the growth of Arabidopsis seedlings in an airtight container was retarded due to insufficient supply of the CO

. When either CO

was introduced into the container, or the seedlings were co-cultured along with certain bacterial species, the plants' growth was restored.

The benefit of co-culturing was largely due to the CO

generated by respiration of the bacteria.

Intracranial pressure (ICP) > 20mmHg is associated with worse outcomes in children. The gold standard for monitoring ICP is invasive, has complications such as bleeding and infection, and may not be available in resource limited areas. Ultrasound of the optic nerve sheath diameter (ONSD) has been studied as a noninvasive way to evaluate for elevated ICP in adults. Its utility in pediatrics remains unclear.

A prospective study was performed in a pediatric intensive care unit in children ≤ 18years old. ONSD ultrasound was performed using a 13-6MHz linear probe with the patient's invasively measured ICP simultaneously recorded. Linear mixed effects models were used to evaluate the association between ONSD and ICP.

One hundred thirty-six measurements were obtained from 16 patients. ONSD was not significantly associated with ICP (p= 0.51). A ROC curve assessing ONSD to determine elevated ICP > 20mmHg had an area under the curve of 0.52 (95%CI = 0.32-0.72). There was no difference in measurements obtained between the left and right ONSD at the same time (p= 0.82).

In conclusion, this study demonstrated no association between ONSD measurement and invasively monitored ICP in critically ill children.

Our aim was to determine that RES induces apoptosis in melanoma cells by regulating miR-492 resulting in decreased CD147 expression. We treated A375 and SK-MEL-28 melanoma cells via RES at different concentrations and time-points. The results have shown that the inhibition rate of A375 and SK-MEL-28 was significantly increased after RES treatment. Subsequently, we investigated cell apoptosis by flow cytometry, as well as detected apoptotic-associated proteins including PARP, Caspase-3, Bcl-2, and Bax by western blotting. Meanwhile, the expression of miR-492 and CD147 was analyzed. We found that RES remarkably induces apoptosis in melanoma cells, along with an upregulation of miR-492 and the inhibition of CD147 expression. Furthermore, the detection of luciferase reporter activity confirmed that miR-492 could target CD147 mRNA, and transfected with mimic miR-492 in cells reduced CD147 expression. We also performed the rescued experiment by using a miR-492 inhibitor in melanoma cells. The results showed that the ability of induced apoptosis by RES in melanoma cells was to be attenuated via inhibiting miR-492 expression resulting in CD147 augment. Finally, we determined that the effect of RES-induced apoptosis in melanoma cells is associated with, at least in part, its ability to regulate the miR-492/CD147 pathway.

To compare the clinical outcomes between patients that underwent transjugular intrahepatic portosystemic shunt (TIPS) via the left and right portal veins (PVs).

All relevant studies in the Pubmed, Embase, and Cochrane Library databases published as of June 2020 were identified by searching, after which RevMan v5.3 was used to conduct the present meta-analysis. Relevant endpoint data were extracted from each study, related to postoperative hepatic encephalopathy (HE) rates, TIPS dysfunction, re-bleeding, and mortality.

A total of eight studies were identified as being relevant for inclusion in this meta-analysis. These studies included 2592 total patients suffering from liver cirrhosis that underwent TIPS treatment via the left (n = 1500) or right (n = 1092) PVs. Rates of postoperative HE were significantly lower in the left PV group relative to the right PV group (5.7% vs. 18.1%, OR 0.19; P < 0.00001), as were rates of TIPS dysfunction (8.1% vs. 16.5%, OR 0.41; P < 0.00001). In contrast, the rates of re-bleeding did not differ significantly between these groups (12.0% vs. 14.9%, OR 0.76; P = 0.11), nor did mortality rates (30.9% vs. 31.0%, OR 0.85, P = 0.22). We did not detect any significant heterogeneity among included studies for any analyzed endpoints, nor was any risk of publication bias pertaining to these studies detected through the use of funnel plots.

TIPS conducted via the left PV was associated with decreased rates of postoperative HE and TIPS dysfunction relative to TIPS conducted via the right PV.

However, most studies have focused on a single trait, while controlling for additional factors in an informal way, generally by excluding taxa. This study utilized a dataset of cytochrome c oxidase subunit I (COI) barcode sequences from over 7000 ray-finned fish species to test the effects of 27 traits on molecular evolutionary rates. Environmental traits such as temperature were considered, as were traits associated with effective population size including body size and age at maturity. It was hypothesized that these traits would demonstrate significant correlations with substitution rate in a multivariable analysis due to their associations with mutation and fixation rates, respectively. A bioinformatics pipeline was developed to assemble and analyze sequence data retrieved from the Barcode of Life Data System (BOLD) and trait data obtained from FishBase.
