Electroencephalography (EEG) is the reference tool for the analysis of brain function, reflecting normal and pathological neuronal network activity. During the neonatal period, EEG patterns evolve weekly, according to gestational age. The first analytical criteria for the various maturational stages and standardized neonatal EEG terminology were published by a group of French neurophysiologists training in Paris (France) in 1999. These criteria, defined from analog EEG, were completed in 2010 with digital EEG analysis. Since then, this work has continued, aided by the technical progress in EEG acquisition, the improvement of knowledge on the maturating processes of neuronal networks, and the evolution of critical care. In this review, we present an exhaustive and didactic overview of EEG characteristics from extremely premature to full-term infants. This update is based on the scientific literature, enhanced by the study of normal EEGs of extremely premature infants by our group of neurophysiologists. For educational purposes, particular attention has been paid to illustrations using new digital tools.Dural plasmacytoma is a type of multiple myeloma of the central nervous system. Our patient presented with symptoms of headache. Imaging findings suspected glioblastoma, whereas pathological findings revealed mucosa-associated lymphoid tissue lymphoma associating with plasma cell differentiation. Further in-depth studies confirmed a diagnosis of dural plasmacytoma. This case indicates that morphological variations may occur in the extramedullary involvement of CD20-positive multiple myeloma. The multidisciplinary team contributes to the diagnosis of hematological diseases.

The quadrivalent human papillomavirus (qHPV; HPV6/11/16/18) vaccine was approved for use in Chinese women aged 20-45years in 2017. This Phase 3, open-label study (NCT03493542) aimed to assess immunogenicity and safety of the qHPV vaccine in Chinese girls aged 9-19years versus Chinese young women aged 20-26years; we report results from Day 1 through Month 7. The study will continue through Month 60 to assess antibody persistence in Chinese girls aged 9-19years.

Participants aged 9-26years received three doses of the qHPV vaccine (Day 1, Month 2, Month 6). Geometric mean titers (GMTs) and seroconversion percentages for anti-HPV6/11/16/18 antibodies were determined by competitive Luminex immunoassay (cLIA) in serum samples obtained on Day 1 and at Month 7. Injection-site adverse events (AEs) and systemic AEs within 30days post-vaccination, and serious AEs (SAEs) occurring at any time during the study, were recorded.

In total, 766 participants (383 aged 9-19years; 383 aged 20-26years) were enrolled and recelly well tolerated in the study population. ClinicalTrials.gov Identifier NCT03493542.

Current human papillomavirus (HPV) vaccine coverage in the United States (in 2019, 66-70%), remains below the Healthy People 2020 coverage goal of 80%. HPV vaccine misinformation, including parental concerns of sexual risk-compensation influence vaccine uptake. We examined the association between HPV vaccination and sexually transmitted infection (STI) outcomes.

Of the 20,146 participants from 2013 to 2014 and 2015-2016 cycles of the National Health and Nutrition Examination Survey, 1050 females aged 18-35 with a history of sexual activity had complete case data. Roa-Scott Chi-squared and F-tests assessed survey-weighted socio-demographic differences between vaccinated and unvaccinated participants. Weighted logistic regression assessed crude and adjusted associations between self-reported HPV vaccination (none vs.≥1dose) and lab-confirmed STIs (trichomonas and chlamydia) and vaccine-type HPV (6/11/16/18). As a sensitivity analysis, we conducted weighted-propensity score (PS) models and inverse probabilitreporting bias, results indicating low vaccine uptake at routine-recommended ages requires additional efforts promoting HPV vaccination before sexual-debut.

Among females who reported a history of sexual activity, HPV vaccination status was protective against vaccine-type HPV and not associated with lab-based STI outcomes. Although findings may be susceptible to reporting bias, results indicating low vaccine uptake at routine-recommended ages requires additional efforts promoting HPV vaccination before sexual-debut.

Hepatitis A virus (HAV) remains a global public health concern, which is potentially growing in Latin America, due to an expected shift from high to intermediate endemicity levels. The use of HAV vaccines in pediatric national immunization programs (NIPs), either as a 2-dose or a 1-dose schedule, has been explored in Latin American countries; however, evidence demonstrating long-term protection in this population is limited in the region. We evaluated long-term antibody persistence following a 1-dose partial series and the recommended 2-dose schedule used in Panama's pediatric NIP.

Two independent cross-sectional serological surveys were conducted at year 8 (Y8) and Y10 following vaccination under the NIP with 1 or 2 doses of an inactivated HAV vaccine (Havrix, GSK). Seropositivity (anti-HAV antibody concentration≥15 mIU/mL) rates and antibody geometric mean concentrations (GMCs) were assessed at each serosurvey. Non-inferiority of 1 dose versus 2 doses was also explored.

This study (NCT02712359) includaccination in Panama. Further investigations are needed to confirm antibody persistence and conclude on the protection afforded beyond 10 years in the pediatric population in Latin America.

The United States military regularly deploys thousands of service members throughout areas of South America and Africa that are endemic for yellow fever (YF) virus. To determine if booster doses might be needed for service members who are repetitively or continually deployed to YF endemic areas, we evaluated seropositivity among US military personnel receiving a single dose of YF vaccine based on time post-vaccination.

Serum antibodies were measured using a plaque reduction neutralization test with 50% cutoff in 682 military personnel at 5-39years post-vaccination. We determined noninferiority of immune response by comparing the proportion seropositive among those vaccinated 10-14years previously with those vaccinated 5-9years previously. Noninferiority was supported if the lower-bound of the 2-tailed 95% CI for p

- p

was≥-0.10. Additionally, the geometric mean antibody titer (GMT) at various timepoints following vaccination were compared to the GMT at 5-9years.

The proportion of military service met U.S. military personnel.The objective of this study was to investigate synergistic antibacterial activity based on a combination of UV-A light and three classes of food grade compounds benzoic acid derivatives, cinnamic acid derivatives, and gallates. By using Escherichia coli O157H7 as the model strain, it was observed that three cinnamic acid derivatives (ferulic acid, coumaric acid, and caffeic acid) and one benzoic acid derivative (2,5-dihydroxybenzoic acid) presented strong synergistic antibacterial activity with UV-A light radiation, where 1 mM levels of these compounds plus with 15 min of UV-A light (total light dose of 6.1 cm-2) led to more than 7-log CFU mL-1 of bacterial inactivation. In contrast, synergistic antibacterial activity between UV-A light and most benzoic acid derivatives (benzoic acid, gallic acid, vanillic acid, and 2,5-dimethoxybenzoic acid) were only observed after higher concentrations of these compounds were applied (10 mM). Lastly, from the three gallates tested (methyl gallate, ethyl gallate, and propylug resistant Salmonella Typhimurium strain.Haloxylon salicornicum is a xero-halophyte growing in saline and arid regions of the world. Metabolite profiling was carried out in shoot of both control and salinity treated (400 mM NaCl) samples by GC-QTOF-MS and HPLC-DAD analysis to decipher the salinity tolerance mechanism in this xero-halophyte. The present study investigates the alteration in metabolite profile of H. salicornicum that support the salinity tolerance of the plant. The metabolomic analysis of H. salicornicum shoot identified 56 metabolites, of which 47 metabolites were significantly changed in response to salinity. These metabolites were mainly included in the category of amino acids, organic acids, amines, sugar alcohols, sugars, fatty acids, alkaloids, and phytohormones. In response to salinity, most of the amino acids were down-regulated except alanine, phenylalanine, lysine, and tyramine, which were up-regulated in H. salicornicum. In contrast to amino acids, most sugars and organic acids were up-regulated in response to salinity. Correlation and pathway enrichment analysis identified important biological pathways playing significant roles in conferring salt tolerance of H. salicornicum. These biological pathways include amino sugar and nucleotide sugar metabolism, citrate cycle (TCA cycle), starch and sucrose metabolism, phenylalanine metabolism, cysteine, methionine, glycine, serine, and threonine metabolism, etc. The data presented here suggest that the modulations of various metabolic pathways facilitate H. salicornicum to survive and grow optimally even under high salinity condition. This study offers comprehensive information on metabolic adaptations and overall salt tolerance mechanisms in H. salicornicum. The information gained through this study will provide guidance to plant breeders and molecular biologists to develop salinity tolerant crop varieties.

The current study aimed at examining a fluoride containing bioactive glass (BiominF®) paste as a temporary filling material capable of remineralizing the demineralized enamel or dentin, and its ability to decrease a simulated dentinal fluids pressure on the resin/dentin interface, without affecting the shear bond strength of a universal bonding agent to enamel and dentin.

60 premolars were utilized for the acid resistance, trans-microradiography (TMR) and shear bond strength (SBS) experiments. Enamel and dentin discs were demineralized for 4 days to create a subsurface demineralized zone followed by applying BiominF® paste, 1.23% acidulated phosphate fluoride, or a temporary filling material for 24 h. 30 extracted human non-carious third molars were utilized for the pulpal pressure experiment in which direct communication to the pulp chamber was created by cutting at a level approximately 1 mm below the cemento-enamel junction while the coronal enamel was ground to expose mid coronal dentin. The dentin su and help to conserve tooth structures by preserving the demineralized enamel and dentin form cutting during cavity preparation.

The aim of this study was to evaluate the effect of preoperative oral carbohydrate administration on patients undergoing Cesarean section with epidural anesthesia.

Randomized controlled clinical study.

A total of 75 patients undergoing Cesarean section (American Society of Anesthesiologists physical status grade I-II) were randomized to preparation with a carbohydrate drink (CHO group), flavored water (placebo group), or to the fasting group. The CHO and placebo groups were double-blinded and given 300mL of the drink 2hours before surgery. Visual analog scores of the patient were assessed to evaluate thirst, hunger, and anxiety level, and the gastric antral cross-sectional areas were recorded by ultrasonography during the operative period. Insulin resistance was calculated on the basis of the blood glucose and insulin levels assessed before administration and after surgery.

The CHO and placebo groups did not show an increase in gastric fluid volumes in terms of gastric antral cross-sectional area, andrst, hunger, and anxiety during the preoperative period for Cesarean section.

Women with hypertensive disorders of pregnancy should have a blood pressure evaluation no later than 7-10 days after delivery. The objective of this study was to identify the factors associated with patient attendance at the postpartum blood pressure follow-up visit.

This was a retrospective cohort study of postpartum women who had a hypertensive disorder of pregnancy. Postpartum follow-up rates were recorded, and characteristics of women who attended a postpartum visit for blood pressure evaluation were compared to women who did not return for the visit. Multiple logistic regression was performed.

Characteristics of women who returned for a blood pressure visit.

There were 378 women who met inclusion criteria; 193(51.1%) attended the blood pressure visit. Women who returned were older and more likely to have preeclampsia, severe features, magnesium sulfate use, or severe hypertension during hospitalization. They were less likely to have gestational hypertension. Adjusted analysis demonstrated that black/non-Hispanic women (OR 0.53, 95% CI 0.34-0.83), the presence of any preeclampsia diagnosis (OR 2.19, 95% CI 1.03-4.81), and whether the woman underwent a cesarean delivery (OR 3.06, 95% CI 1.85-5.14) remained significant factors in predicting adherence.

Women who returned for a blood pressure visit were more likely to have had significant hypertensive disease or a cesarean delivery. Non-Hispanic black women had the lowest rate of follow-up. Given black women have the highest rates of maternal morbidity and mortality nationwide, effective interventions to increase follow-up for them are needed.

In this paper, we successfully realize the conversion of mechanical energy through a friction route on the tribocatalyst of Bi2WO6. Under magnetic stirring, the friction between the PTFE-sealed magnetic bar and the catalyst particles resulted in the electron transfer crossing the contact interface, in which PTFE accepted the electrons and simultaneously the holes were left on the catalyst. The positively charged catalyst was demonstrated through electrostatic attraction and repulsion tests. Like photocatalytic process, the holes on the valence band of Bi2WO6 have strong oxidative ability that can efficiently oxidize organic pollutants. The tribocatalytic tests showed that the Bi2WO6 could eliminate organic dyes under magnetic stirring in dark, and we could further optimize the tribocatalytic performance via regulating the size of magnetic bar and reactor material. Finally, a high stability of tribocatalysis was revealed by the multiple tests. This work not only develops a green tribocatalysis strategy to oxidative purification of organic pollutants, but also provides a possible pathway to convert mechanical energy in environment to chemical energy, such as potential applications in environmental remediation and sustainable energy.Semiconductor-based photocatalytic hydrogen evolution is considered to be a promising and cost-effective approach to address the environmental issues and energy crisis. It still remains a great challenge to design highly-efficient semiconductor photocatalysts via a facile method. Herein, hierarchically porous hydrangea-like In2S3/In2O3 heterostructures are successfully synthesized via a simple in situ oxidization process. The formed In2S3/In2O3 heterostructures exhibit superior photocatalytic activity to the counterpart In2S3 and In2O3. The boosted photocatalytic performance is ascribed to the formed heterostructures, which greatly facilitate the interfacial charge transfer. Moreover, the formation of hierarchically porous heterostructures increases the number of active sites and improves the permeability, and thus significantly promotes the photocatalytic H2 evolution activity. This work may provide a new insight for designing In2S3-based heterostructures for efficient solar light conversion.The surface of poly (p-phenylene benzobisoxazole) (PBO) fibers with self-healing and ultraviolet (UV)-resistance performance play the key role in prolonging their service lifespan. Although great advances have been made in the single aspect of above two properties, integration of self-healing and anti-UV performance into the surface of PBO fiber is still a challenge. In this study, the coagulation strategy mediated by metal-organic framework (MOF) is proposed to construct the multifunctional surface of PBO fibers. The spindle-like iron (III)-based MOF (MIL-88B-NH2) nanocrystals are firstly immobilized onto the surface of PBO-COOH through hydrothermal reaction, then serving as the medium layer to further immobilize sufficient graphene oxide (GO) nanosheets. Benefitting from the favorable near-infrared (NIR, 808 nm) photothermal conversion performance of GO nanolayers, the monofilament composite-PBO@Fe-MIL-88B-NH2-GO-TPU (thermoplastic polyurethane) exhibited a stable and high self-healing efficiency (approximately 80%) within five cycle times. Meanwhile, the cooperative adsorption and shielding weaken effects of MOF-GO nanolayers enabled PBO fibers with excellent anti-UV properties that are superior to much reported literatures after 96 h aging time and eventually increased by 75% compared with untreated PBO fiber. In view of the varieties and multifunctionalities of MOFs and carbon nanomaterials, MOF-mediated coagulation strategy would provide guidance for preparing multifunctional composite materials.

Biomimetic liquid crystalline systems are widely used in skin care cosmetics and topical pharmaceutical preparations. Our ability to rationally design such formulations, however, is hampered by our incomplete understanding of their structure on the nanoscale.

Using polarized light microscopy and small-angle and wide-angle X-ray scattering, the molecular architecture and properties of a barrier formulation prepared from distearoylphosphatidylcholine mixed with long chain fatty acid and alcohols, with and without antimicrobial pentanediols are directly probed. The nature and composition of the phases identified are determined through small-angle neutron scattering studies using chain-deuterated components, and the detailed structure and dynamics of the gel network lamellae are determined through molecular dynamics simulations.

The formulations show molecular ordering with long and short periodicity lamellar phases and there is little change in these structures caused by changes in temperature, drying, or the application of shear stress. The diol-free formulation is demonstrated to be self-preserving, and the added pentanediols are shown to distribute within the interlamellar regions where they limit availability of water for microbial growth. In culmination of these studies, we develop a more complete picture of these complex biomimetic preparations, and thereby enable their structure-based design.

Using survey-based analysis, we compared the quality of life in infants with deformational plagiocephaly with a cohort of their healthy peers. In addition, we compared infant quality of life before and after helmet therapy to evaluate the impact of this mainstay therapy for deformational plagiocephaly. Our results demonstrated that infants with plagiocephaly and their caregivers had a significantly decreased quality of life compared with healthy controls. This reframes our understanding of deformational plagiocephaly and emphasizes the need for therapeutic intervention in these individuals. A common therapeutic option - helmet remolding therapy - was shown to have no negative impact on quality of life, underscoring this as an appropriate therapeutic option. These data will allow us to counsel our future parents more effectively regarding the impact of deformational plagiocephaly and helmet therapy.

The geographic distribution of practicing radiation oncologists is of concern for multiple stakeholders within the field. Employment outcomes of graduating residents can affect that distribution, and they are of major concern to current residents. Data investigating employment outcomes of recent graduates are sparse. We aimed to analyze the employment outcomes of the radiation oncology residency class of2019.

Using publicly available information, we identified the employment of 179 of 183 graduating residents in the class of 2019. For each, the place of employment, residency program, and medical school were geocoded using Google Maps. We used the rural-urban continuum code (RUCC) published by the United States Department of Agriculture to determine the rurality of each location and compared employment outcomes by RUCC and program size.

Two thirds of graduates (66%) took a position in a county within a metropolitan area with a population greater than 1,000,000 people; only 3.4% took a position in a count to produce graduates that practice in similar settings, but those graduates might not do so locally. We advocate for a centralized, prospective data collection of employment outcomes for graduating residents to refine these analyses and to reduce employment prospect information asymmetry for trainees.Primary lateral sclerosis is a disorder categorized by insidious onset of progressive upper motor neuron dysfunction without lower motor neuron involvement. PLS often presents with gradual-onset, progressive lower extremity stiffness and pain due to muscle spasticity. Intrathecal Baclofen pumps (ITB) have been used to effectively treat spasticity in several neurologic conditions including MS and spinal cord injury. This study aimed at reviewing a cohort of PLS patients with spasticity requiring ITB to assess the clinical course, benefits, and complications in these patients. A series of 5 patients were identified who were diagnosed with PLS and received ITB as treatment for spasticity. The average age of the patients at the time of ITB insertion was 56.4 years. The average length of treatment was 10.4 years with a range of 4-15 years. All patients reported improvement in spasticity as measured by clinical examinations and Ashworth scores; 1/5 had complications with the pump related to migration of catheter. No patients required permanent removal of the ITB. ITB is a safe and effective treatment for spasticity in PLS and should be considered in other patients.The degradation of an anticancer drug by laccase was investigated for the first time, bringing a new approach to treat these hazardous substances through the direct enzymatic application. Degradations of doxorubicin by laccase were performed in different enzymatic concentrations, pH values and temperatures through kinetic studies. The highest enzymatic degradation of doxorubicin was achieved at pH 7 and 30 ºC, which resembles effluent characteristics from wastewater treatment plants. Assays were carried out in different doxorubicin concentrations to comprehend the enzymatic kinetics of degradation. Michaelis-Menten kinetic parameters obtained were maximum velocity obtained (Vmax) of 702.8 µgDOX h-1 L-1 and Michaelis-Menten constant (KM) of 4.05 µM, which showed a good affinity for the substrate. The toxicity was evaluated against L-929 cell line, and the degraded doxorubicin solution did not show a reduction in cell viability in the concentration of 250 µg L-1. In contrast, the doxorubicin shows a reduction of 27% in cell viability. Furthermore, in the highest tested concentration (1000 µg L-1), enzymatic degradation reduced in up 41.4% the toxicity of doxorubicin, which indicates laccase degrades doxorubicin to non-toxic compounds. In conclusion, this study provides a new application to laccase since the results showed great potential to remove anticancer drugs from effluents.The Ce/Eu redox pair-functionalized HKUST-1 MOF, as an innovative environmentally friendly and recyclable sono-photocatalyst, was hydrothermally mixed and fully characterized by XRD, PL, EIS, FE-SEM, EDS, Mott-Schottky, chronoamperometry, and DRS techniques. The obtained chemical and optical characteristics of the n-type Ce/Eu-HKUST-1 MOF showed that the transfer of additional 4f orbital electrons in the Ce/Eu redox pair improves the sono-photocatalytic activity. The performance of Ce/Eu-HKUST-1 MOF for the sono-photodegradation of Malathion (MA) was evaluated in the aqueous media in the simultaneous presence of blue light and ultrasonic irradiation. The optimization of the process was cross-examined using the response surface methodology as a function of the MA concentration (15-35 mg·L-1), Ce/Eu-HKUST-1 mass (10-30 mg), pH (4-12), and ultrasonic wave irradiation duration (10-30 min). The maximum sono-photocatalytic degradation capacity was found to be 99.99% under the optimum conditions set as 25 mg·L-1, 20 mg, 8, and 25 min for the concentration of Malathion, photocatalyst mass, pH, and irradiation duration, respectively. These findings were attributed to the suppression of electron-hole pair recombination, increased life-time of charge carriers, enhanced visible light absorption, and prominent proportion of hydroxyl and peroxide radicals formed.

The purpose of this study is to report the outcomes of a series of orbital fracture repairs, their assessment with the Hess area ratio (HAR%), and the use of unsintered hydroxyapatite (HA) implants for reconstruction.

This study involved 207 consecutive unilateral orbital fractures with symptomatic diplopia that underwent surgical repair within 28 days of injury. Ocular movement was measured presurgery and at 3 and 6 months postsurgery by Hess chart with calculation of the HAR%.

Surgery was conducted on 207 patients (161 males and 46 females; mean age, 27.8years) at a mean of 9.9days postinjury and with a mean follow-up of 8.6months. There were 160 patients with orbital floor fractures, 27 with medial wall fractures, and 20 with combined orbital medial wall and floor fractures, 135 of 207 patients had orbital blowout fractures, and 72 had orbital trap-door fractures. The HAR% improved significantly from a mean of 73.8% preoperatively to 92.7% postoperatively (P<.01). Orbital fractures were reconstructed with either unsintered HA particles/poly l-lactide composite sheet (133 patients), a silicone silastic sheet (47 patients), a combination of sheets (15 patients), or without an implant (12 patients). There was no significant difference in the HAR% improvement between the different implants.

Very good outcomes can be achieved with early orbital floor fracture repair surgery, which can be assessed preoperatively and postoperatively by HAR%. Unsintered HA/poly l-lactide composite sheets are an effective absorbable material for orbital floor fracture reconstruction.

To systematically review the effect of core stability exercises in addition to usual care physiotherapy on patient outcomes after stroke.

Cumulative Index to Nursing and Allied Health, MEDLINE, Physiotherapy Evidence Database (PEDro), PubMed, and EMBASE were searched to November2018.

Eleven randomized controlled trials that compared usual care physiotherapy with usual care physiotherapy with additional core stability exercises in people with stroke were included. The initial search yielded 1876 studies.

Two independent reviewers applied inclusion and exclusion criteria and extracted data on methodological quality using the PEDro scale, participant characteristics, intervention details, outcome measures, and results.

Postintervention means and SDs were pooled to calculate either the standardized mean difference (SMD) or the mean difference (MD) and 95% CIs using a random-effects model and inverse variance methods. There was moderate quality evidence to suggest the addition of core stability exercisesility exercises should be included in rehabilitation if improvements in these domains will help clients achieve their goals. Future trials should consider incorporating outcomes of body kinematics during functional tasks to assess movement quality and assess participation outcomes.Agricultural expansion and intensification has led globally to a rapid landscape structure change and high agrochemical use resulting in habitat loss and degraded environmental quality. Co-occurrence of landscape change and agrochemical contamination threatens biodiversity and might have interactive effects especially for organisms with complex life-cycles such as amphibians. We evaluated effects of landscape structure and agrochemical contamination at different spatial scales on anurans in Entre Rios, Argentina. We selected 35 independent stream headwaters along an agricultural expansion and intensification gradient. We conducted anuran call surveys from spring 2012 to summer 2013 and obtained detection-non detection data to estimate mean richness and focal species occupancy. We quantified forest area and riparian forest width at two spatial scales (sub-basin and local reach scale). We measured nutrients and pesticides in water and sediment. We evaluated anuran response to landscape and contamination variables using GLMs for richness and single season single-species occupancy models for focal species. Anuran diversity increased with forest area and riparian forest width, and decreased at sites with herbicide and nutrient contamination, particularly glyphosate; 2,4-D and nitrates. Also, most focal frog species responded mainly to basin forest and 2,4-D. Negative effects of agrochemical contamination on anuran diversity was mitigated in areas with larger basin forest cover. Agricultural management should ensure the reduction of herbicide and fertilizer use, the sparing of adequate forested habitat within drainage areas, and preservation of riparian forests around anuran breeding habitat to reduce and mitigate the negative effects of agrochemical contamination on anurans diversity in agroecosystems.Particulate matter (PM) is a crucial health risk factor for respiratory and cardiovascular diseases. The smaller size fractions, ≤2.5 μm (PM2.5; fine particles) and ≤0.1 μm (PM0.1; ultrafine particles), show the highest bioactivity but acquiring sufficient mass for in vitro and in vivo toxicological studies is challenging. We review the suitability of available instrumentation to collect the PM mass required for these assessments. Five different microenvironments representing the diverse exposure conditions in urban environments are considered in order to establish the typical PM concentrations present. The highest concentrations of PM2.5 and PM0.1 were found near traffic (i.e. roadsides and traffic intersections), followed by indoor environments, parks and behind roadside vegetation. We identify key factors to consider when selecting sampling instrumentation. These include PM concentration on-site (low concentrations increase sampling time), nature of sampling sites (e.g. indoors; noise and space will be an ufficient PM mass for various purposes in a reasonable timeframe.Cyanobacterial harmful algal blooms (CyanoHABs) are pervasive and negatively impact lake water quality, resulting in economic losses and public health risks through exposure to cyanotoxins. Therefore, it is critical to better monitor and understand the complexity of CyanoHABs, but current methods do not fully describe the spatial and temporal variability of bloom events. In this work, we developed a framework for a multiscale and multi-modal monitoring approach for CyanoHABs combining drone-based near-range remote sensing with analytical measurements of microcystin cyanotoxins and chlorophyll-a. We analyzed weekly beach monitoring samples from 37 lakes geographically distributed across the state of Iowa (USA) over a 15-week period in the summer of 2019 to quantify ELISA (bioassay), 12 microcystin congeners (LC-MS/MS), and chlorophyll-a. We developed a novel microcystin congener-normalized equivalent toxin metric to compare CyanoHAB impacted waters; this microcystin-LR normalized sum-of-congeners approach yields lower predicted toxicity than parallel ELISA results suggesting ELISA is conservative for assessment. A significant linear relationship existed between chlorophyll-a and microcystin for lakes throughout Iowa (R2 = 0.39, p less then 0.001); lakes with low watershedlake area ratio and long residence times exhibited a stronger correlation. We then developed a novel geometry-based image processing approach to allow for stitching over-water drone images, a previous barrier in photogrammetry. We applied our mutli-modal framework to a case study on Green Valley Lake to assess initial viability and predicted microcystin concentrations within 33%. We concluded that multispectral imaging is possible but may presently be insufficient for predicting microcystin concentrations due to limitations in the spectral capabilities of the multispectral camera, but technologies are quickly advancing, and lightweight hyperspectral imaging could soon become feasible for investigating spatial bloom variability on lakes.Rare mutations in genes originally discovered in multigenerational families have been associated with increased risk of Parkinson's disease (PD). The involvement of rare variants in DNAJC13, UCHL1, HTRA2, GIGYF2, and EIF4G1 loci has been poorly studied or has produced conflicting results across cohorts. However, they are still being often referred to as "PD genes" and used in different models. To further elucidate the role of these 5 genes in PD, we fully sequenced them using molecular inversion probes in 2408 patients with PD and 3444 controls from 3 different cohorts. A total of 788 rare variants were identified across the 5 genes and 3 cohorts. Burden analyses and optimized sequence Kernel association tests revealed no significant association between any of the genes and PD after correction for multiple comparisons. Our results do not support an association of the 5 tested genes with PD. Combined with previous studies, it is unlikely that any of these genes plays an important role in PD. Their designation as "PARK" genes should be reconsidered.

Tonsillectomy is one of the most common surgeries performed in the pediatric population. Although different forms of instruments and various methods are used to perform tonsillectomy, none of them is still recognized as the best global technique. This study aimed to compare the outcomes of the new Bipolar Loop tonsillectomy versus bipolar diathermy technique.

This study is a pilot randomized clinical trial and was conducted on 40 pediatric patients who were the candidate of tonsillectomy. Patients were divided into two groups of Bipolar Loop or bipolar diathermy. Operation time, intraoperative bleeding, tonsillar fossa wound, postoperative complications, and duration of return to normal diet were evaluated in the current study.

In both of the Bipolar Loop and bipolar diathermy groups, no significant difference was found in terms of sex, age, and weight. The average amount of the operative time, intra-operative blood loss, and postoperative pain loss were significantly less in the Bipolar Loop group (P<.001). In addition, the tonsillar fossa wound healing scores were significantly better (on the 14th day, P=0.009). However, there was no significant difference between the two groups in terms of postoperative bleeding, duration of return to a normal diet, and postoperative symptoms of fever, otalgia, or voice change between the groups.

The study showed that blood loss and postoperative pain through day 7 were significantly less in the Bipolar Loop group. Tonsillectomy with Bipolar Loop can be recommended as one of the methods for tonsillectomy, especially in pediatric patients.

The study showed that blood loss and postoperative pain through day 7 were significantly less in the Bipolar Loop group. Tonsillectomy with Bipolar Loop can be recommended as one of the methods for tonsillectomy, especially in pediatric patients.In this work, the synthesis through solid state reaction and the thermoluminescence (TL) characterization of pellet shaped CaZrO3 samples is reported. X-ray diffraction confirms that orthorhombic CaZrO3 was obtained. The glow curve has two maxima located at 149 and 216 °C as well as a less intense maximum around 350 °C when a 5.0 °C/s heating rate is used after 64 Gy of beta particle exposure. A remarkably reproducibility of the TL response is observed in repeated irradiation - TL readouts cycles. The TL as a function of the dose displays linear dependence in the dose range from 0.5 to 256 Gy. The intensity of the maximum located around 216 °C remains 61% 14 days after irradiation, and then remains closely constant for longer times. The synthesized CaZrO3 exhibits TL properties potentially of interest for use in radiation detection and dosimetry.In our previous research, a new detection method was proposed to measure Hg and Pb simultaneously by combining Prompt Gamma-ray Neutron Activation Analysis (PGNAA) and X-ray Fluorescence (XRF) and proved by the Monte Carlo N-Particle (MCNP) simulation code. For further experimental verification, a combined measurement experimental facility, comprising an 241Am-Be neutron source, SAINT-GOBAIN Bismuth Germanate (BGO) as the γ-ray detector, and an NaI detector with 25 μm Be window as the X-ray detector, was presented. Specifically, the characteristic X-ray fluorescence of the Hg directly induced in this experimental facility was utilized to improve the limits of detection (LOD) of Hg instead of traditional excitation sources. The simulation and experiment results indicated that LOD for Hg by the combined measurement instrument was 19.4 mg kg-1. The empirical formula of the calibration curve in this method was given based on the aforementioned calculations.

High-translucency ceramics can be influenced by the underlying structure, altering the restoration shade. How this affects color matching is unclear.

The purpose of this invitro study was to investigate the optical effects of cement shade, ceramic type, ceramic thickness, and abutment material on the final color of computer-aided design and computer-aided manufacturing (CAD-CAM) ceramic restorations.

Two shades of resin cement (yellow, translucent), 3 types of background (titanium, white zirconia, yellow zirconia), and 3 types of high-translucent ceramic (each type shade A1 and A3) were used in this study. For the experimental groups, a total of 72 ceramic specimens were produced across 4 groups based on ceramic thickness (1.0 mm, 1.5 mm, and 2.0 mm). For the control groups, each ceramic type and shade was prepared at a thickness of 4 mm. A total of 8 resin cement specimens were produced in 4 groups based on shade by using a plastic mold (12×12×0.2 mm). To demonstrate the effect of implant abutment mateup was similar when using the 2 cement shades (P>.05).

An increase in ceramic thickness could minimize alteration of the final shade. High-translucency ceramics, together with a resin cement, were able to successfully mask titanium with a ceramic thickness of at least 1.5 mm. However, only a ceramic with a thickness of 2.0 mm was able to mask the yellow zirconia background.

Computer-aided design and computer-aided manufacturing (CAD-CAM) systems are increasingly used to fabricate removable complete dentures. However, comparisons and analyses of the trueness and adaptation of the socketed surface of denture bases produced by milling (MIL) and digital light processing (DLP) are lacking.

The purpose of this invitro study was to evaluate and compare the trueness and socketed surface adaptation of denture bases fabricated by using additive and subtractive manufacturing.

Based on a denture base standard tessellation language (STL) file, a total of 15 denture bases were produced by using DLP (horizontal and vertical direction) and MIL. The intaglio and cameo surfaces of the fabricated denture bases were scanned with a dental scanner. The scanned intaglio and cameo surfaces were overlapped with the corresponding reference denture base STL file for trueness evaluation. In addition, the ridge lap STL file of the diagnostic tooth arrangement, in which reverse normal was performed, wan the DLP groups (HDB and VDB).

We sought to assess the performance of a comprehensive machine learning (ML) risk score integrating circulating biomarkers and computed tomography (CT) measures for the long-term prediction of hard cardiac events in asymptomatic subjects.

We studied 1069 subjects (age 58.2±8.2 years, 54.0% males) from the prospective EISNER trial who underwent coronary artery calcium (CAC) scoring CT, serum biomarker assessment, and long-term follow-up. Epicardial adipose tissue (EAT) was quantified from CT using fully automated deep learning software. Forty-eight serum biomarkers, both established and novel, were assayed. An ML algorithm (XGBoost) was trained using clinical risk factors, CT measures (CAC score, number of coronary lesions, aortic valve calcium score, EAT volume and attenuation), and circulating biomarkers, and validated using repeated 10-fold cross validation.

At 14.5±2.0 years, there were 50 hard cardiac events (myocardial infarction or cardiac death). The ML risk score (area under the receiver operator characteristic curve [AUC] 0.81) outperformed the CAC score (0.75) and ASCVD risk score (0.74; both p=0.02) for the prediction of hard cardiac events. Serum biomarkers provided incremental prognostic value beyond clinical data and CT measures in the ML model (net reclassification index 0.53 [95% CI 0.23-0.81], p<0.0001). Among novel biomarkers, MMP-9, pentraxin 3, PIGR, and GDF-15 had highest variable importance for ML and reflect the pathways of inflammation, extracellular matrix remodeling, and fibrosis.

In this prospective study, ML integration of novel circulating biomarkers and noninvasive imaging measures provided superior long-term risk prediction for cardiac events compared to current risk assessment tools.

The use of participatory methodologies in urban health diagnoses is key to capturing the different perspectives and knowledge of the local context, contributing to a more complete analysis of reality. This methodological note presents the development of the participatory process carried out as part of the Bilbao health diagnosis; the identification of participating agents and selection criteria, the invitation to participate and the dynamics developed. Sharing experiences that have incorporated participatory processes is necessary to foster its methodological development, and thus, to promote it practice.The COVID-19 pandemic has necessitated the rapid implementation of telemedical health services. In the United Kingdom, one service that has benefitted from this response is the provision of early medical abortion. England, Wales, and Scotland have all issued approval orders to this effect. These orders allow women to terminate pregnancies up to certain gestational limits, removing the need for them to contravene social distancing measures to access care. However, they are intended only as temporary measures for the duration of the pandemic response. In this paper, we chart these developments and further demonstrate the already acknowledged politicisation of abortion care. We focus on two key elements of the orders (1) the addition of updated clinical guidance in the Scottish order that suggests an extended gestational limit, and (2) sunset clauses in the English and Welsh orders, as well as an indication of similar intentions in Scotland. In discussing these two issues, we suggest that the refusal of UK governments to introduce telemedical provision of early medical abortion previously has not been based on health concerns. Further, we question whether it would be appropriate for the approval orders to be lifted following the pandemic, suggesting that to do so would represent regressive and harmful policy.

To evaluate the impact of hip arthroscopy for femoroacetabular impingement (FAI) on both the physical and mental components of the 36-Item Short Form (SF-36) and assess how changes in health status compare with improvements in physical function and ability to continue to play (CTP) 2 years after surgery.

Data collected prospectively from male athletes undergoing primary arthroscopic correction of FAI between November 2008 and October 2016 were analyzed. Physical (PCS) and mental (MCS) component scores of the SF-36 were assessed preoperatively and 2 years postoperatively. The minimal clinical important difference (MCID) was calculated using an anchor-based percentage of possible improvement technique, and the proportion of athletes achieving MCID was established. Logistic regression analysis was used to identify predictors of achieving MCID. CTP was assessed at 2-year follow-up.

486 cases were included, age 25.9 ± 5.6 years. Median PCS improved from baseline 69.4 (51.9 to 85.0) to 91.9 (81.9 to 97.5) at n of cases failed to meet MCID for the MCS compared with PCS (85% versus 60%, P < .001).

Arthroscopic management of sports-related FAI results in excellent overall clinical outcome and high levels of satisfaction and CTP at 2 years. Chronic hip injury has a significant negative effect on the physical and mental well-being of athletes; corrective surgery may restore physical function but is more limited in its ability to improve mental health status in this athletic cohort.

To evaluate the prevalence of preoperatively diagnosed psychiatric comorbidities and the impact of these comorbidities on the healthcare costs of ten common orthopaedic sports medicine procedures.

Patients undergoing 10 common sports medicine procedures from 2007 to 2017q1 were identified using the Humana claims database. These procedures included anterior cruciate ligament reconstruction; posterior cruciate ligament reconstruction; medial collateral ligament repair/reconstruction; Achilles repair/reconstruction; Rotator cuff repair; meniscectomy/meniscus repair; hip arthroscopy; arthroscopic shoulder labral repair; patellofemoral instability procedures; and shoulder instability repair. Patients were stratified by preoperative diagnoses of depression, anxiety, bipolar disorder, or schizophrenia. Cohorts included patients with ≥1 psychiatric comorbidity (psychiatric) versus those without psychiatric comorbidities (no psychiatric). Differences in costs across groups were compared using Mann-Whitney U tests,costsfollowing all investigated orthopaedic sports medicine procedures.

We examine colorectal cancer (CRC) survival for patients with and without severe psychiatric illness (SPI) to demonstrate the use of relative and absolute effects.

This included a retrospective cohort study of patients with CRC diagnosed between 01/04/2007 and 31/12/2012. SPI was defined as major depression, bipolar disorder, schizophrenia, and other psychotic illnesses occurring six months to five years preceding cancer diagnosis and categorized as inpatient, outpatient, or none. Associations between SPI history and death were examined using Cox proportional hazards regression (hazard ratios (HRs)) and Aalen's semiparametric additive hazards regression (absolute differences).

A total of 24,507 patients with CRC were included. A total of 58.1% of patients with inpatient SPI history died, and 47.1% of patients with outpatient SPI history died. Patients with an outpatient SPI history had a 40% (HR 1.40, 95% confidence interval 1.22-1.59) increased hazard of death, and patients with an inpatient SPI history had a 91% increased hazard of death (HR 1.91, 95% confidence interval 1.63-2.25), relative to no history of a mental illness. Outpatient SPI history was associated with additional 33 deaths per 1000 person years, and inpatient SPI was associated with additional 82 deaths per 1000 person years.

We encourage future studies examining inequities with time-to-event data to use this method addressing both relative and absolute effect.

Alterations in bone and mineral metabolism are very common in chronic kidney disease (CKD). The increase in phosphate levels leads to bone disease, risk of calcification and greater mortality, so any strategy aimed at reducing them should be welcomed. The latest drug incorporated into the therapeutic arsenal to treat hyperphosphataemia in CKD is sucroferric oxyhydroxide (SFO).

To analyse the efficacy and safety of SFO in 3 cohorts of patients, one with advanced CKD not on dialysis, another on peritoneal dialysis and the last on haemodialysis, followed for 6 months.

A prospective, observational, multicentre study in clinical practice. Clinical and epidemiological variables were analysed. The evolution of parameters relating to alterations in bone and mineral metabolism and anaemia was analysed.

Eighty-five patients were included in the study (62±12 years, 64% male, 34% diabetic), 25 with advanced CKD not on dialysis, 25 on peritoneal dialysis and lastly, 35 on haemodialysis. In 66 patients (78%), SFO was the first phosphate binder; in the other 19, SFO replaced a previous phosphate binder due to poor tolerance or efficacy.
