The combination of metagenomic and metatranscriptomic analysis in this study allowed us to specifically link ARGs to their transcripts, providing a comprehensive view of the prevalence and expression of ARGs in gut microbiota. Taken together, these data deepen our understanding of the distribution, evolution, and dissemination of ARGs and metal resistance genes in human, chicken, and pig gut microbiota. Volatile and hazardous compounds are formed during the chlorination of pool water. Monitoring components in the air, such as the four trihalomethanes; chloroform, dichlorobromomethane, dibromochloromethane and bromoform (tTHM), is challenging. this website Carbon dioxide (CO2) sensors are used for controlling air quality in different buildings and can be installed in ventilation systems for continuous surveillance and monitoring purposes. However, such sensors are not used in indoor swimming facilities. In this study, samples of tTHM and CO2 were collected and analysed, along with other air and water quality parameters such as combined chlorine, to evaluate whether CO2 sensors could be used to explain the observed variability in the tTHM concentration in an indoor swimming facility and thereby reduce the exposure of individuals utilising the pool to tTHM. Random intercept models were built for the tTHM and CO2 concentrations, respectively, and the results show that the relationships between combined chlorine in the water, CO2 in the air and number of occupants explain 52% of the variability in tTHM. The correlation between occupancy and CO2 concentration (ρ = 0.65, p ≤ 0.01) suggests that CO2 sensors should be used so that the air supply corresponds to the demand of the users. INTRODUCTION Prophylactic central neck node dissection (CND) for pediatric patients with papillary thyroid cancer (PTC) is still controversial. We aimed to identify the incidence and the predictive parameters of the central lymph node metastasis (CLN) in pediatric patients with cN0 PTC. METHODS This retrospective study had included 32 pediatric patients with cN0 PTC who underwent total thyroidectomy and prophylactic CND from 2015 to 2019. RESULTS The proportion of CLN metastasis was 75.0%. Univariate logistic regression demonstrated that CLN metastasis was associated with age (≤15 years; p = 0.028), tumour size > 1 cm (p = 0.008), multifocality (p = 0.028) and external extension (p = 0.041) Multivariate logistic regression revealed that age (≤15 years), multifocality, tumour size (>1 cm) and external extension were independent risk factors of CLN metastasis in pediatric patients. CONCLUSIONS In summary, central lymph node metastasis occurred in 75% of cN0 pediatric patient and were more common in larger tumour size (>1 cm), multifocal tumours, extrathyroidal extension, and younger age. OBJECTIVES Analyze reasons for unilateral conductive hearing loss (CHL) with unknown etiology in children. INTRODUCTION Unilateral conductive hearing loss (HL) without known etiology can be undiagnosed despite of hearing screening programs. It can be difficult to find the reason for HL and to make a treatment plan. Middle ear endoscopy gives hard-evidence diagnosis and basis for an individual treatment plan. METHODS AND MATERIAL Prospective clinical follow-up study for a cohort of generally healthy elementary school age children with unilateral conductive HL with unknown etiology. The study population was 192 children, of which 46 had a HL of at least 25 dB with more than 10 dB conductive component. Mean age was 8.7 years. Preoperative tests included otomicroscopy, bone- and air-conduction audiogram, tympanometry, stapes reflex tests, Rinne and Weber test and Otoacoustic emissions. The children underwent endoscopy of the middle ear with an individual treatment plan and long-term follow-up. The aim was to expltponed or avoided. OBJECTIVE To observe the difference in ce
