Smartphones allow good quality recordings; however, it cannot be claimed that the acoustic parameters obtained from them are comparable to those obtained with a professional microphone. The objective of this study is to establish whether there are significant differences when comparing the values of six acoustic parameters obtained from recordings using four smartphones and a professional microphone. The Praat programme was used to obtain the acoustic parameters f0, Jitter, Shimmer, HNR, Alpha Ratio and L1 - L0 of the recording of a sustained vowel /a/ using iPhone SE, iPhone 6, Samsung S8, Huawei Y7 and the Behringer ECM8000 microphone. The sample was made up of 26 men and 26 women, from 18 to 26 years old without declared voice pathology. The repeated sample ANOVA test was used to compare the values. All the equipment show reproducibility between consecutive repeated measurements. BAY1000394 The parameters f0 and Jitter were the only ones that did not show significant differences between the smartphones and the professional microphone. None of the smartphones studied can replace the professional microphone in voice recording for the evaluation of the six parameters analysed, except for f0 and Jitter.Objectives Blood stream infections (BSIs) are the main cause of morbidity and mortality in children worldwide. The present study was carried out to determine the prevalence of BSI with a focus on the identification of the causative agent of BSI, and to further evaluate the antibiotic susceptibility profile of the causing bacterial pathogens.Methods A cross-section study was carried out at the tertiary care hospital in Peshawar, Pakistan from January to December, 2018. Blood samples were collected in BACTECTM bottles and standard microbiological protocols were applied for the isolation and identification of bacterial strains. The antibiotic susceptibility tests were performed using disc diffusion method as per the 2014 guideline of Clinical Laboratory Standard Institute (CLSI).Results Of 567 blood cultures in total, 111(19.6%) were positive for BSI. Male children were 64 % (71/111) and female children were 36% (40/111). For the causative predominant group of microorganisms, Gram-negative bacteria were identified in 79 (71.1%) isolates, and Gram-positive bacteria in 32 (28.9%) isolates. The common bacteria of isolates were S. typhi (n=35, 31.5%), E. coli (n=19, 17.1%), S. aureus (n=18, 16.2%), K. pneumonia (n=12, 10.8%), and Enterococcus species (n=7, 6.3%). The 36.7% (29/79) isolates of Gram-negative bacteria were ESBL producers, and 61.1% (11/18) of S. aureus isolates were methicillin resistant. Overall, 72.9% isolates were multidrug resistant.Conclusions Gram-negative bacteria were the main cause of pediatric BSIs, where the predominant microorganism was S. typhi. Remarkably, majority of the S. typhi isolates were resistant to ciprofloxacin.

Healthcare associated infections (HAI) are estimated to affect up to 15% of hospital inpatients in low-income countries (LICs). A critical but often neglected aspect of HAI prevention is basic environmental hygiene, particularly surface cleaning and linen management. TEACH CLEAN is an educational intervention aimed at improving environmental hygiene. We evaluated the effectiveness of this intervention in a pilot study in three high-volume maternity and newborn units in Dar es Salaam, Tanzania.

This study design prospectively evaluated the intervention as a whole, and offered a before-and-after comparison of the impact of the main training. We measured changes in microbiological cleanliness [Aerobic Colony Counts (ACC) and presence of Staphylococcus aureus] using dipslides, and physical cleaning action using gel dots. These were analysed with descriptive statistics and logistic regression models. We used qualitative (focus group discussions, in-depth interviews, and semi-structured observation) and quantitroved microbiological cleanliness is a key step on the pathway to infection prevention in hospitals. Future research should assess whether this bundle is cost-effective in reducing bacterial and viral transmission and infection using a rigorous study design.

The evaluation suggests that improvements in microbiological cleanliness are possible using this intervention and can be sustained. Improved microbiological cleanliness is a key step on the pathway to infection prevention in hospitals. Future research should assess whether this bundle is cost-effective in reducing bacterial and viral transmission and infection using a rigorous study design.

Echinococcus multilocularis is a small tapeworm affecting wild and domestic carnivores and voles in a typical prey-predator life cycle. In Italy, there has been a focus of E. multilocularis since 1997 in the northern Italian Alps, later confirmed in red foxes collected from 2001 to 2005. In this study, we report the results of seven years of monitoring on E. multilocularis and other cestodes in foxes and describe the changes that occurred over time and among areas (eco-regions) showing different environmental and ecological features on a large scale.

Eggs of cestodes were isolated from feces of 2872 foxes with a sedimentation/filtration technique. The cestode species was determined through multiplex PCR, targeting and sequencing ND1 and 12S genes. Analyses were aimed to highlight variations among different eco-regions and trends in prevalence across the study years.

Out of 2872 foxes, 217 (7.55%) samples resulted positive for cestode eggs at coproscopy, with differences of prevalence according to year, posed categories.

Breast cancer bone metastasis has become one of the most common complications; however, it may cause cancer recurrence and bone nonunion, as well as local bone defects.

Herein, In vitro, we verified the effect of bioscaffold materials on cell proliferation and apoptosis through a CCK8 trial, staining of live/dead cells, and flow cytometry. We used immunofluorescence technology and flow cytometry to verify whether bioscaffold materials regulate macrophage polarization, and we used ALP staining, alizarin red staining and PCR to verify whether bioscaffold material promotes bone regeneration. In vivo, we once again studied the effect of bioscaffold materials on tumors by measuring tumor volume in mice, Tunel staining, and caspase-3 immunofluorescence. We also constructed a mouse skull ultimate defect model to verify the effect on bone regeneration.

Graphene oxide (GO) nanoparticles, hydrated CePO

nanorods and bioactive chitosan (CS) are combined to form a bioactive multifunctional CePO

/CS/GO scaffold, with characteristics such as photothermal therapy to kill tumors, macrophage polarization to promote blood vessel formation, and induction of bone formation.
