v-Smirnov and Anderson-Darling tests. Although, systematic discrepancies between TGDRcalc and TGDRobs were observed for sedimentary rocks, the compatibility of the RMP and LIT databases can be considered acceptable, which implies that the estimation of the contents of terrestrial radionuclides using literature data for large-scale mapping of U, Th and K contents in geological units is reasonable.Causal mechanisms for broad-scale reef fish diversity patterns are poorly understood and current knowledge is limited to trends of species richness. This work compared the effects of ecological drivers on components of fish diversity across reefs spanning over 2.000 km of the tropical Brazilian coastline. A quarter of communities' diversity is accountable to common and dominant species, while remaining species are rare. Low-latitude sites were more diverse in rare species. Communities along the coast share common and dominant species, which display high densities across all reefs, but differ in rare species that show abundance peaks in particular reef morphotypes. The disproportionate distribution of rare species reveals a higher vulnerability of these communities to impacts and stochastic density fluctuations. Uneven conservation efforts directed to these morphotypes pose a threat to the maintenance of a paramount component of the reef fish diversity represented by rare species.
The treatment of choice for pediatric OSAHS is surgical. However, its etiopathogenesis is multifactorial and surgery does not always solve it. Therefore, other modalities of treatment are used. The main objective of this study is to shed light on the efficacy of surgery compared to other treatments.
Prospective cohort study with 317 children ages 1-13 years and apnea-hypopnea index (AHI) ≥3/h with no previous treatment. The treatment was organised into 3 categories surgical (n=201), medical (n=75) and observation (n=41). Quality of life and sleep was assessed by two validated questionnaires (PSQ & Esteller et al.) The upper airway was explored, and nocturnal polysomnography (PSG) performed in every patient. After 12±3 months of treatment was completed, a new PSG and questionnaires were evaluated.
The surgical group improved significantly both subjectively and objectively. #link# Mean AHI decreased from 7.95/h to 2.57/h and T 90 (time spent with arterial oxygen saturation <90%) from 0.49 to 0. link2 AHI of the medical group decreased only from 5.09/h to 4.9/h. Subjective parameters improved less than in the surgical group. Persistence after surgery was 31%, 50% following medical treatment, and after observation 75%. There were no differences in age and BMI between groups. Age or obesity showed no relationship with treatment success or failure.
The best results were achieved in surgically treated children. However, 31% of those operated had OSAHS persistence, which means a combination of treatments may be the most appropriate strategy.

The study aimed to analyze the developmental mode of auditory at the level of brainstem in preschool autistic children using click-evoked auditory brainstem response (click-ABR).
Twenty children with autism spectrum disorder (ASD) and 20 age matched typical development children (TD) were recruited. OTX008 cell line recorded from click-ABR were collected at two time periods (T1 and T2).
There was no significant change in TD group at two time periods. In ASD group, wave V latency was significantly shortened at T2 compared to that recorded at T1. The interpeak latency of I-V was short at T2 versus at T1 in the autistic children. Compared to the TD group, ASD was associated with longer latencies for waves V and longer interpeak latencies of I-III, I-V at T1. In addition, ASD group also indicated longer latencies of wave III and wave V, longer interpeak latencies of I-III and I-V at T2 compared to the TD group.
ASD group had immature and dysfunction developmental mode in auditory stimuli perception at the level of brainstem. The performance of auditory ability in children with ASD improved gradually with ages. However, there are still differences compared with TD children.

RPA with mediastinal abscess requires prompt surgical management, generally via external or transoral approach. We present the case of a 3-year-old boy with RPA with mediastinal extension who was managed with a unique multidisciplinary surgical approach with otolaryngology and interventional radiology. A transoral approach was utilized to pass a transnasal drain with image guidance into the mediastinal fluid collection. This report reviews the presentation and surgical management of RPA with mediastinal extension and describes a unique minimally invasive approach to drainage.
The Italian Guideline for the management of acute otitis media (AOM) in children has been recently updated. We conducted a cross-sectional survey to investigate the adherence of Italian primary care paediatricians to the guideline recommendations.
A questionnaire including 13 closed-ended questions was administered to the paediatricians participating in the 24th National Congress of Practical Pediatrics, held in Florence in November 2019. The answers were collected and analyzed.
Eight hundred fifty-four out of 1000 questionnaires were collected (85.4%). Most of the participants declared that they did not remove the cerumen (63.9%). Pneumatic otoscope and tympanometry were routinely used by a minority of paediatricians (9.6% and 3.9%, respectively); all the participants declared to routinely prescribe oral analgesic drugs and 97.6% of them considered amoxicillin or amoxicillin/clavulanic acid as the first-choice antibiotic. In an uncomplicated unilateral AOM case, the preferred strategy was immediate antt use of antibiotics in terms of optimal dosage, duration and number of daily administrations, and to implement proper AOM prevention strategies.
Our data suggest adequate adherence of the guideline recommendations considering the preferred antibiotic drug, pain management and the choice between immediate antibiotic therapy and watchful waiting. Conversely, targeted training programs are needed to improve adherence to recommendations on cerumen removal, use of pneumatic otoscopy, correct use of antibiotics in terms of optimal dosage, duration and number of daily administrations, and to implement proper AOM prevention strategies.
To evaluate the factors contributing to middle ear pathology, hearing and speech development among cleft palate children treated for middle ear effusion.
A prospective cross-sectional otoscopic and audiological analysis was conducted on 102 cleft palate children (204 ears) aged 1-18 years old who were treated for middle ear effusion at our centre. Retrospective chart review was done to determine patient characteristics and prior patient management. The aim was to assess the effect of ventilation tube insertion (VTI) on hearing, speech and chronic otitis media; comparing the timing and number of ventilation tubes per ear and determining other factors affecting the short-term and long-term outcome.
68 children or 130 ears (63% of all cases) were selectively treated with ventilation tube insertion. Repeat procedures (more than 2) were performed in 41 ears. Among children with VTI performed, the incidence of chronic otitis media in children after the age of 4 was 17%. Overall, abnormal tympanic membrane finvative approach especially when considering repeated tube insertions. A long-term follow-up paired with interval hearing assessment is advocated until early adulthood.
Treatment with early ventilation tube insertion prior to the age of one year provides a hearing benefit in children less than 4 years of age, but no significant difference after 4 years of age. Factors significantly affecting the outcome after 4 years of age was the timing of palatal closure and total number of tube insertions. We recommend a conservative approach especially when considering repeated tube insertions. A long-term follow-up paired with interval hearing assessment is advocated until early adulthood.The effect of breathing parameters on the airway deposition of the inhaled aerosols with known size was intensively studied in the literature. However, in the case of dry powder aerosol drugs both the quantity and quality of the particles emitted by the inhaler and inhaled by the patients is a complex function of the patient's breathing parameters, which in turn depend also on the disease severity and current status of the patient. The aim of this study was to evaluate the impact of breathing parameters, gender, age, symptoms and exacerbation history related disease severity (GOLD groups) of chronic obstructive pulmonary disease (COPD) patients on the lung dose of four different drugs emitted by three DPIs (dry powder inhalers). Breathing profiles of 47 COPD patients were recorded while they inhaled through Turbuhaler®, Breezhaler® and Genuair® inhalers. Patient specific emitted doses and particle size distributions were determined for Symbicort® Turbuhaler®, Onbrez® Breezhaler®, Seebri® Breezhaler® and Bretaignificantly higher deposition for drugs emitted by Breezhaler® and Genuair®. Lung doses of two different drugs dispensed in the same inhaler can be significantly different.In this study, we examined differences in resting-state functional connectivity between sub-regions of the Default Mode Network (DMN) and whole brain voxels in 22 individuals with high schizo-obsessive traits (SOT), 30 with high schizotypal traits (SCT) alone, 20 with high obsessive-compulsive traits (OCT) alone and 30 with low trait scores (LT). We found that the SOT group showed the most reduced functional connectivity within the DMN compared with the other groups. The SOT group also showed increased connectivity between the DMN and the Salience Network, and between the DMN and the Auditory Network compared with the LT group. The SCT group exhibited increased connectivity between the DMN and the Salience Network, and between the DMN and the Executive Control Network (ECN) compared with the LT group. The OCT group exhibited decreased connectivity within the DMN, between the DMN and the Salience Network, and between the DMN and the ECN compared with the LT group. These findings highlight different changes in DMN-related functional connectivity associated with high SOT, SCT and OCT traits and may provide insight into the dysfunctional brain networks in the early stage of schizophrenia spectrum disorders.
Previous studies have thoroughly elucidated the exposure-response relationship between ambient temperature and hand, foot, and mouth disease (HFMD), whereas very little concern has been to the lag-response relationship and related key time points.
We aimed to clarify the temporal characteristics of the lag-response relationship between ambient temperature and HFMD and how they may vary spatially.
We retrieved the daily time series of meteorological variables and HFMD counts for 143 cities in mainland China between 2009 and 2014. We estimated the city-specific lag-response curve between ambient temperature and HFMD and related key time points by applying common distributed lag nonlinear models (DLNM) and Monte Carlo simulation methods. Then, we pooled the city-specific estimates by performing a meta-regression with the city-specific characteristics as meta-predictors to explain the potential spatial heterogeneity.
We found a robust lag pattern between temperature and HFMD for different levels of temperatures.
