BACKGROUND: Intra-operative quantification of the ossicle mobility could provide valuable feedback for the current status of the patient's conductive hearing. However, current methods for evaluation of middle ear mobility are mostly limited to the surgeon's subjective impression through manual palpation of the ossicles. This study investigates how middle ear transfer function is affected by stapes quasi-static stiffness of the ossicular chain. The stiffness of the middle ear is induced by a) using a novel fiber-optic 3-axis force sensor to quantify the quasi-static stiffness of the middle ear, and b) by artificial reduction of stapes mobility due to drying of the middle ear...

Quercetin (QU) has been shown obvious anti-arthritic property in pre-clinical studies or clinical studies. Howbeit, the underlying mechanism of it is still not revealed distinctly and should be gotten further insight into. QU at a dosage of 150 mg/kg was administered orally in collagen-induced arthritis rats and then the clinical symptoms were monitored. The protein levels of Th17/Treg-related cytokines were determined by ELISA, and the mRNA levels of cytokines and transcription factors associated with the Th17 and Treg phenotypes were evaluated by real-time PCR, the proportions of Th17 and Treg cells were assessed by flow cytometry...

BACKGROUND: The Montpellier protocol for intubating patients in the intensive care unit (ICU) is associated with a decrease in intubation-related complications. We sought to determine if implementation of a simplified version of the Montpellier protocol that removed selected components and allowed for a variety of pre-oxygenation modalities increased first-pass intubation success and reduced intubation-related complications. METHODS: A prospective pre/post-comparison of a modified Montpellier protocol in two medical and one medical/surgical/cardiac ICU within a hospital system...

Potassium ferrate (K2FeO4) is an effective oxidant that may be used as a pre- or post-oxidant in the purification of source water with cyanobacterial issues. To provide a better basis for the application of this oxidant during water treatment processes, the impacts of K2FeO4 on the cell viability of Microcystis aeruginosa and the fate of associated microcystins (MCs) were investigated in various water matrices. The results showed that a water matrix can significantly affect the effectiveness of K2FeO4 on cyanobacteria inactivation...

As an attempt to control bacterial cross-contamination of beef carcasses, in the present investigation acetic acid and lactic acid (3% v/v) were used for bacterial decontamination. For the decontamination, cows were sprayed with each above acid at two different stages; (i) on live animal's hides, (ii) on carcass surfaces immediately after slaughter. Microbiological samples were taken on different hide areas of animals before spraying and on carcass surfaces at 24h after spraying. Meat quality traits were also analyzed on the sprayed animals...

The enthesis, or interface between bone and soft tissues such as ligament and tendon, is prone to injury and often does not heal post-surgical intervention. Interface tissue engineering represents an integrative strategy for regenerating the native enthesis by functionally connecting soft and hard tissues and thereby improving clinical outcome. This review focuses on integrative and cell-instructive scaffold designs that target the healing of the two most commonly injured soft tissue-bone junctions: the tendon-bone interface (e...

INTRODUCTION: The transition from pre-dialysis chronic kidney disease (CKD) to post-dialysis start is a critical period associated with high patient mortality and increased hospital admissions. Little is known about the trends of key clinical and laboratory parameters through this time of transition to start dialysis. METHODS: De-identified data including demographics, vital signs, lab results, and eGFR from the Fresenius Medical Care-CKD Registry were analyzed to determine trends in clinical and laboratory parameters through the time of transition from 12 months pre-dialysis start to 12 months post-dialysis start...

AIMS AND OBJECTIVES: To improve the prevention, detection, and treatment of perioperative inadvertent hypothermia (PIH) in adult surgical patients by implementing a Thermal Care Bundle. BACKGROUND: Keeping patients normothermic perioperatively prevents adverse surgical outcomes. Hypothermia leads to serious complications including increased risk of surgical bleeding, surgical site infections, and morbid cardiac events. The Thermal Care Bundle consists of three elements: 1) assess risk; 2) record temperature; and (3) actively warm...

PURPOSE: The purpose of this study is to measure people's accuracy when they estimate what proportion of their nightly sleep at home is supine vs. non-supine. METHODS: A series of patients referred for obstructive sleep apnea (OSA) evaluation were asked if they "knew with confidence" how they slept with regard to their body position. "Yes" responders were then asked to estimate what percentage of their sleep was supine vs. non-supine. This value was compared with the actual proportion of supine vs...

To be effective, therapeutic cancer vaccines should stimulate both an effective cell-mediated and a robust cytotoxic CD8+ T-cell response against human papillomavirus (HPV)-infected cells to treat the pre-existing tumors and prevent potential future tumors. In this study, the therapeutic experiments were designed in order to evaluate antitumor effect against the syngeneic TC-1 tumor model. The anti-tumor efficacy of a HPV-16 E7 DNA vaccine adjuvanted with melatonin (MLT) was evaluated in a C57BL/6 mouse tumor model by measuring tumor growth post vaccination and the survival rate of tumor-bearing mice, analyzing the specific lymphocyte proliferation responses in control and vaccinated mice by MTT assay...

BACKGROUND: In January 2014, a national bowel cancer screening program started in the Netherlands. The program is being implemented in phases until 2019. Due to this program, an increase in patients referred for a colorectal resection for benign, but endoscopically unresectable polyps, is expected. So far, most resections are performed according to oncological principles despite no pre-operative histological diagnosis of malignancy. The aim of this study was to analyze the increase in referred patients during the first year of the screening program and to compare pathological results and clinical outcome of resections of patients undergoing resection for benign polyps before and after implementation of screening...

Analgosedation is a fundamental part of traumatic brain injury (TBI) treatment guidelines, encompassing both first and second tier supportive strategies. Worldwide analgosedation practices continue to be heterogeneous due to the low level of evidence in treatment guidelines (level III) and the choice of analgosedative drugs is made by the treating clinician. Current practice is thus empirical and may result in unfavourable (often hemodynamic) side effects. This article presents an overview of current analgosedation practices in the paediatric intensive care unit (PICU) and addresses pitfalls both in the short and long term...

PURPOSE: Despite the enormity of the problem and the lack of new therapies, research in the pre-clinical arena specifically using pediatric traumatic brain injury (TBI) models is limited. In this review, some of the key models addressing both the age spectrum of pediatric TBI and its unique injury mechanisms will be highlighted. Four topics will be addressed, namely, (1) unique facets of the developing brain important to TBI model development, (2) a description of some of the most commonly used pre-clinical models of severe pediatric TBI including work in both rodents and large animals, (3) a description of the pediatric models of mild TBI and repetitive mild TBI that are relatively new, and finally (4) a discussion of challenges, gaps, and potential future directions to further advance work in pediatric TBI models...

Bovine follicular fluid (FF) constitutes the microenvironment of follicles and includes various biologically active proteins. We performed a study involving 18 healthy non-lactating Holstein cows to determine the protein expression profile of FF at key-stages of follicular development. Follicles were individually aspirated in vivo at pre-deviation (F1∼7.0mm); deviation (F1∼8.5mm); post-deviation (F1∼12.0mm); and pre-ovulatory stages of follicle development, which were confirmed by measurement of follicular estradiol and progesterone concentrations...

BACKGROUND: Postoperative acute kidney injury (AKI) is common following cardiac surgery (CS). Body weight (BW) may be an amenable variable by representing the summation of the nutritional and the fluid status. However, the predictive role of perioperative BW changes in CS patients with severe postoperative AKI is never explored. This study aimed to evaluate this association. METHODS: This study was conducted using a prospectively collected multicenter cohort, NSARF (National Taiwan University Hospital Study Group on Acute Renal Failure) database...

BACKGROUND: The treatment of sacral fractures has evolved since its first description in 1982. Several techniques for sacral augmentation have been developed since 2001, and the rate of improvement is rapid with over 50% reduction in pain achieved prior to post-procedure discharge of the patient. Pain reduction occurs primarily within the first 3 months and is sustained at 12 months; however, the long-term outcomes have not previously been studied. OBJECTIVES: We aim to evaluate the long-term efficacy of sacroplasty versus non-surgical management (NSM) in treating sacral insufficiency fractures (SIFs), including the effect on pain relief, opioid and other analgesic use, patient satisfaction, and complication rates...
