1 %, respectively, in SMG cultures, while similar reductions were also seen in the flask and NG cultures. These results illustrate the potential applicability of B. bacteriovorus HD100 as an antibiotic to combat the ever-growing threat of multidrug-resistant (MDR) pathogens during spaceflight, such as in the International Space Station (ISS).

There is very limited information about the effect of continuous positive airway pressure (CPAP) in the very elderly. Here we aimed to analysed the effect of CPAP on a clinical cohort of patients with obstructive sleep apnea (OSA) ≥80 years old.

Post-hoc pooled analysis of two open-label, multicenter clinical trials aimed to determine the effect of CPAP in a consecutive clinical cohort of elderly (≥70 years old) with moderate-to-severe OSA (apnea-hipopnea index ≥15 events/hour) randomized to receive CPAP or no CPAP for three months. Those consecutive patients ≥80 years old were included in the study. The primary endpoint was the change in Epworth Sleepiness scale (ESS). Secondary outcomes included sleep-related symptoms, quality of life, neurocognitive and mood status as well as office blood pressure measurements.

From the initial 369 randomized individuals with ≥70 years, 97 (26.3%) with ≥80 years old were included (47 in the CPAP group and 50 in the no-CPAP group). The mean (SD) age was 81.5 (2.4) years. Average use of CPAP was 4.3 (2.6) hours/night (53% with good adherence) Patients in the CPAP group significantly improved snoring and witnessed apneas as well as AHI (from 41.9 to 4.9 events/hour). However no clinical improvements were seen in ESS (-1.2 points, 95%CI, 0.2 to-2.6), any domain of QSQ, any neurocognitive test, OSA-related symptoms, depression/anxiety or blood pressure levels.

The present study does not support the use of CPAP in very elderly patients with moderate-to-severe OSA.

Sleep disorders (SD) are very common in childhood, especially in certain genetic syndromes. Tuberous Sclerosis Complex (TSC) is a genetic syndromesassociated with a high rate of SD, although these are still under-recognized. The aim of this study was to assess the prevalence of SD in TSC, and to evaluate the relationship between sleep, epilepsy and TSC-associated neuropsychiatric disorders (TAND).

We administered the Sleep Disturbance Scale for Children (SDSC) and the Epworth Sleepiness Scale for Children and Adolescents (ESS-CHAD) to parents of 177 children with TSC referring to different Italian centers. We also collected information on epilepsy and TAND.

SDSC score was positive in 59.3% of patients, being positive in 30.4% of patients without and in 63.6% of those with epilepsy (p=0.005). However, in a multivariate logistic model considering antiseizure medications and nocturnal seizures, epilepsy ceased to be a significant risk factor for positive SDSC (OR=2.4; p=0.17). As for TAND, SDSC was positive in 67.9% of patients with and in 32.5% of those without TAND (p<0.001). After adding in a multivariate logistic model active epilepsy, age, and pharmacotherapies, TAND continued to be a significant risk factor for positive SDSC (p=0.01, OR=1.11).

Our results revealed a high prevalence of SD in children with TSC. Epilepsy didn't increase the risk for SD, while a very strong association was found with TAND. An early detection of SD is of utmost importance in order to plan an individualized treatment, that in some cases might also ameliorate behavior and attention.

The need for an effective tool to predict prognosis of head and neck squamous cell carcinoma (HNSCC) patients is critical and unmet. Microbiota has recently been found involved in tumor progression and response to immunotherapy. However, the association of microbiota with the prognosis of HNSCC patients remains obscure. This study aims to investigate the association between tumor microbiota and outcomes of HNSCC patients.

A retrospective study including 129 primary tumors of HNSCC was conducted. Using 16S rRNA sequencing, the profile and the composition of tumor microbiota were measured and their associations with overall survival (OS) and disease free survival (DFS) were examined.

We observed a reduced richness and enriched abundances of genera Schlegelella and Methyloversatilis in tumor microbiota of HNSCC patients with poor prognosis. However, a richer tumor microbiota with greater abundances of genera Bacillus, andLactobacillusandSphingomonas was characterized in the patients with favorable prognosis.The ratio of these differentially abundant taxa, microbial dysbiosis index (MDI), was significantly associated with OS (hazard ratio [HR], 4.67, 95% confidence interval [CI], 2.51 to 8.69,P< 0.001) and DFS (HR, 2.89; 95% CI, 1.74 to 4.80,P< 0.001) independently of age, tumor size, lymph node metastasis, differentiation and p16 status. Fasoracetam ic50 The risk score of multivariate Cox regression exhibited an excellent performance for estimating three-year OS (AUC of 0.826). We also founda richer tumor microbiota was correlated with moderate peritumoral inflammatory infiltration.

These results indicate that tumor microbiota associates with outcomes of HNSCC patients.

Though several landmarks have been described to locate the nerve trunk, variations do exist due to the physical and racial characteristics of an individual. The spiral ladder technique described here uses multiple landmarks that appear in a stepwise manner as a beginner proceeds through the surgery as a road map to the nerve trunk. This simple adoption of a cluster of existing landmarks increases the certainty factor. This method may help beginners and in turn, reduce the chances of iatrogenic facial nerve injuries.We explored somatic mutations in dysplastic sinonasal inverted papilloma (SNIP), SNIP with concomitant sinonasal squamous cell carcinoma (SNSCC), and SNSCC without preceding SNIP. Ten SNIP and SNSCC samples were analyzed with exome sequencing and tested for human papillomavirus. The identified mutations were compared to the most frequently mutated genes in head and neck squamous cell carcinoma (HNSCC) in the COSMIC database. Exome sequencing data were also analyzed for mutations not previously linked to SNSCC. Seven of the most commonly mutated genes in HNSCC and SNSCC in COSMIC harbored mutations in our data. In addition, we identified mutations in 23 genes that are likely to contribute to SNIP and SNSCC oncogenesis.Primary oral melanoma (POM) is a rare entity that is often asymptomatic and is associated with a poor prognosis. Following the example of the ABCDE acronym for the clinical diagnosis of early cutaneous melanoma, we would like to introduce another acronym, AEIOU, to identify lesions that are clinically suspicious for POM. The letter "A" means age older than 50; "E" means ethnicity in reference to the higher occurrence among Asians, Hispanics, and Africans; "I" means irregularity in reference to irregular borders or color; "O" means oral palate, the most frequent site of POM; and "U" means ulceration. To the best of our knowledge, this paper is the first to describe an acronym AEIOU as a diagnostic aid for POM among health practitioners and the general population. Future studies should test the acronym's sensitivity and specificity for POM diagnosis in clinical practice.In this study, an emulsion stabilized by soy protein isolate (SPI)-pectin (PC) complexes was prepared to investigate the effects of high-intensity ultrasound (HIU) treatment (150-600 W) on the physicochemical properties, microstructure, and stability of emulsions. The results found that the emulsion treated at 450 W showed the best emulsion stability index (ESI) (25.18 ± 1.24 min), the lowest particle size (559.82 ± 3.17 nm), the largest ζ-potential absolute value (16.39 ± 0.18 mV), and the highest adsorbed protein content (27.31%). Confocal laser scanning microscopy (CLSM) and atomic force microscopy (AFM) revealed that the emulsion aggregation was significantly improved by ultrasound treatment, and the average roughness value (Rq) was the smallest (10.3 nm) at 450 W. Additionally, HIU treatment reduced the interfacial tension and apparent viscosity of the emulsion. Thermal stability was best when the emulsion was treated at 450 W, D43 was minimal (907.95 ± 31.72 nm), and emulsion separation also improved. Consequently, the creaming index (CI) was significantly decreased compared to the untreated sample, indicating that the storage stability of the emulsion was enhanced.The objective of the present study was to assess the effects of ultrasound pretreatment on the quality of dry-cured yak meat. The ultrasonic power with 0, 200, 300 and 400 W (ultrasonic frequency of 20 kHz) were used to assist processing of dry-cured yak meat. The meat quality, nutrient substances, sensory quality, electronic nose, electronic tongue and volatile compounds of dry-cured yak meat were determined. The results indicated that the moisture content and hardness value of ultrasonic treatment group was significantly lower compared to the control group (P less then 0.05). Ultrasonic treatment increased the value of b*, and decreased the value of L*, a*, pH, chewiness, melting temperature and enthalpy. Springiness value significantly increased from control group to 300 W of ultrasonic power group. Shear force significantly decreased with the increase of ultrasonic power (P less then 0.05). Ultrasonic treatment had no effect on the TVB-N content, but it could increase the TBARS content. Ultrasonic treatment could significantly increase the essential FAA (EFAA) and total FAA (P less then 0.05). In addition, the saturated fatty acid (SFA) content significantly increased with the increase of ultrasonic power (P less then 0.05). Ultrasound treatment negatively affected the meat's color, smell, and taste but increased its tenderness and the overall acceptability. It also significantly increased alcohols and aldehydes contents (P less then 0.05), which were consistent with the measurement of electronic nose and electronic tongue. The results demonstrated that the the appropriate ultrasonic power assisted in the processing improves quality of dry-cured yak meat, particularly for the power of 300 W.An ultrasonic-assisted technique was first introduced for the production of natural rubber latex foam (NRLF). The flexible elastomeric foam was formed by a liquid-solid state transformation in an aqueous media. The aim of the current research was to provide a novel strategy for fabricating NRLF using ultrasonication and the Dunlop method, as well as to simultaneously utilize irradiation events to achieve the desired foam properties. NRLFs were exposed to ultrasonication at 25 kHz at the beginning of the gelling process. The effects of irradiation times of 0, 1, 3, 5 and 7 min on the morphology, foaming behaviors, physical properties and mechanical performance of NRLFs were investigated. The results revealed that using ultrasonic irradiation, unfoamed regions and a bimodal structure, which seem to be microstructural defects in conventional NRLF, could be completely eliminated. However, excessive irradiation times of 5 min and longer appeared to affect the physico-mechanical properties of the foams in terms of transient cavitation and the unfavorable physicochemical effects of ultrasonic vibrations.
