Telemedicine for the pediatric preoperative assessment during the COVID-19 pandemic: Evaluating patient and provider satisfaction.

The COVID-19 pandemic has presented unprecedented challenges in delivering healthcare to surgical patients. To avoid delays in patient care while still minimizing COVID-19 infection risk to patients and providers, anesthesiology preoperative clinics were presented with the opportunity to implement telemedicine to assess patients' risks prior to surgery. This study explores patient and provider satisfaction with video-based telemedicine preoperative clinic visits during the COVID-19 pandemic via a patient and provider satisfaction survey.

Restoration of Proximal Contacts in Decayed Primary Molars Using Three Different Matrix Systems in Children Aged 5-9 Years: An Study.

Aims And Objectives: Proximal contacts and their interdigitation through occlusal contact with opposing teeth play a major role in children, for the eruption of permanent teeth into normal position. Determining the ideal matrix band system for proximal restorations helps in the construction of contacts and contours. This study is designed to determine the most suitable matrix band system for proximal restorations.

Children's Hospital Ambulatory Response to the 2019 Novel Coronavirus Disease (COVID-19) Pandemic.

The 2019 novel coronavirus disease (COVID-19) pandemic produced an abrupt and near shutdown of nonemergent patient care. Children's National Hospital (CNH) mounted a multidisciplinary, coordinated ambulatory response that included supply chain management, human resources, risk management, infection control, and information technology. To ensure patient access, CNH expanded telemedicine and instituted operational innovations for outpatient procedures.

Discharge Communication Practices for Children With Medical Complexity: A Retrospective Chart Review.

Objectives: Children with medical complexity (CMC) have an increased risk of adverse events after hospital discharge. Authors of previous studies have evaluated discharge communication practices with primary care providers (PCPs) in adults and general pediatric patients. There is a lack of evidence surrounding hospitalist communication practices at discharge for CMC.

Comparison between Rotary (Mtwo) and Manual (H-Files) Techniques for Instrumentation of Primary Teeth Root Canals.

Background: The aim of the study is to compare instrumentation time between manual (H-files) and rotary (Mtwo) files along with patient and operator compliance in primary lower molars.

Materials And Methods: 30 primary teeth were selected and divided into two groups of 15 in each group instrumented with H-files and Mtwo files respectively. Time taken for instrumentation was calculated using stop watch.

Use of an animated emoji scale as a novel tool for anxiety assessment in children.

Background: Dental anxiety in children is a major barrier in patient management. If dental anxiety in pediatric patients is assessed during the first visit, it will not only aid in management but also help to identify patients who are in need of special care to deal with their fear. Nowadays, children and adults are highly interested in multimedia and are closely associated with them.

Effect of vibration during local anesthesia administration on pain, anxiety, and behavior of pediatric patients aged 6-11 years: A crossover split-mouth study.

Background: Uncooperative behavior of children due to dental anxiety may interfere with the effective delivery of dental care and compromise the quality of treatment provided. Injection of local anesthesia is one of the most anxiety-inducing stimuli in pediatric dentistry. This study aimed to compare the efficacy of a child-friendly device, having a combined effect of vibration and distraction, with the conventional method of injection on pain, anxiety, and behavior of pediatric patients aged 6-11 years.

Factors influencing methylmercury contamination of black bass from California reservoirs.

Understanding how mercury (Hg) accumulates in the aquatic food web requires information on the factors driving methylmercury (MeHg) contamination. This paper employs data on MeHg in muscle tissue of three black bass species (Largemouth Bass, Spotted Bass, and Smallmouth Bass) sampled from 21 reservoirs in California. During a two-year period, reservoirs were sampled for total Hg in sediment, total Hg and MeHg in water, chlorophyll a, organic carbon, sulfate, dissolved oxygen, pH, conductivity, and temperature.

A Healthy Toddler With Fever and Lethargy.

A 21-month-old previously healthy girl presented to the emergency department initially with fever, rhinorrhea, and poor oral intake. She was subsequently discharged from the hospital on amoxicillin for treatment of acute otitis media but presented hours later on the same day with continued poor oral intake, decreased urine output, and lethargy. The patient was afebrile on examination without a focal source of infection or evidence of meningismus, but she was lethargic and minimally responsive to pain and had reduced strength in the upper and lower extremities.

Comparison of three behavior modification techniques for management of anxious children aged 4-8 years.

Background: An inability to cope with threatening dental stimuli, i.e., sight, sound, and sensation of airotor, manifests as anxiety and behavioral management problems.

A clinical comparative study between conventional and camouflaged syringes to evaluate behavior and anxiety in 6-11-year-old children during local anesthesia administration-a novel approach.

Background: The sight of dental injection can bring about severe anxiety in children. Therefore, an alternative method that is convenient, effective, and keeps the needle hidden making it child friendly is necessary. The objective of the study was to compare the efficacy of a camouflaged syringe and conventional syringe on behavior and anxiety in 6-11-year-old children during local anesthesia administration.

Correction: The biology of environmental stress: molecular biomarkers in Sydney rock oysters (Saccostrea glomerata).

Correction for 'The biology of environmental stress: molecular biomarkers in Sydney rock oysters (Saccostrea glomerata)' by D. A. Raftos et al.

The biology of environmental stress: molecular biomarkers in Sydney rock oysters (Saccostrea glomerata).

This review describes our recent work on environmental stress in Sydney rock oysters, focusing on the identification of molecular biomarkers for ecotoxicological analysis. We begin by describing the environmental pressures facing coastal estuaries in Australia, with particular reference to Sydney Harbour. After providing that context, we summarise our transcriptional and proteomic analyses of Sydney rock oysters responding to chemical contamination and other forms of environmental stress.

Rapid transcriptional acclimation following transgenerational exposure of oysters to ocean acidification.

Marine organisms need to adapt in order to cope with the adverse effects of ocean acidification and warming. Transgenerational exposure to CO2 stress has been shown to enhance resilience to ocean acidification in offspring from a number of species. However, the molecular basis underlying such adaptive responses is currently unknown.

Differential proteomic response of Sydney rock oysters (Saccostrea glomerata) to prolonged environmental stress.

Exposure to prolonged environmental stress can have impacts on the cellular homeostasis of aquatic organisms. The current study employed two-dimensional electrophoresis (2-DE) to test whether exposure to impaired water quality conditions in the Sydney Harbour estuary has significantly altered the proteomes of the resident Sydney rock oyster (Saccostrea glomerata). Adult S.

Proteomic analysis of hemolymph from poly(I:C)-stimulated Crassostrea gigas.

Synthetic double stranded RNA (Poly(I:C)) injection of Crassostrea gigas results in a systemic antiviral response involving many evolutionary conserved antiviral effectors (ISGs). Compared to mammals, the timing of C. gigas ISG expression to viral or poly(I:C) injection is delayed (>12 h p.

Meta-analysis of studies using suppression subtractive hybridization and microarrays to investigate the effects of environmental stress on gene transcription in oysters.

Many microarray and suppression subtractive hybridization (SSH) studies have analyzed the effects of environmental stress on gene transcription in marine species. However, there have been no unifying analyses of these data to identify common stress response pathways. To address this shortfall, we conducted a meta-analysis of 14 studies that investigated the effects of different environmental stressors on gene expression in oysters.

A tiered assessment framework to evaluate human health risk of contaminated sediment.

For sediment contaminated with bioaccumulative pollutants (e.g., PCBs and organochorine pesticides), human consumption of seafood that contain bioaccumulated sediment-derived contaminants is a well-established exposure pathway.

Pediatric hospitalist comanagement of surgical patients: structural, quality, and financial considerations.

Comanagement of surgical patients is occurring more commonly among adult and pediatric patients. These systems of care can vary according to institution type, comanagement structure, and type of patient. Comanagement can impact quality, safety, and costs of care.

The discrepancy in concentration of metals (Cu, Pb and Zn) in oyster tissue (Saccostrea glomerata) and ambient bottom sediment (Sydney estuary, Australia).

The current study aimed to examine the relationship between metals in sediments and metal bioaccumulation in oyster tissue in a highly-modified estuary (Sydney estuary, Australia). While extensive metal contamination was observed in surficial sediments, suspended particulate matter and oyster tissue, a significant relationship between these media could not be established. No relationship was determined between sediment quality guidelines and oyster size or weight, nor with human consumption levels for metals in oyster tissue.

Mussel Watch update: long-term trends in selected contaminants from coastal California, 1977-2010.

This study examined trends in contaminants measured during three decades of "Mussel Watch" monitoring on the California coast. Chlorinated organic contaminants and butyltins declined the most rapidly, with tissue concentrations in 2010 that were up to 75% lower than during the 1980s. Silver and lead declined at about half of the stations statewide, but generally exhibited slower rates of decline relative to the organic compounds.

Seasonal and annual trends in forage fish mercury concentrations, San Francisco Bay.

San Francisco Bay is contaminated by mercury (Hg) due to historic and ongoing sources, and has elevated Hg concentrations throughout the aquatic food web. We monitored Hg in forage fish to indicate seasonal and interannual variations and trends. Interannual variation and long-term trends were determined by monitoring Hg bioaccumulation during September-November, for topsmelt (Atherinops affinis) and Mississippi silverside (Menidia audens) at six sites, over six years (2005 to 2010).

Benthic macrofaunal assemblages of the San Francisco Estuary and Delta, USA.

The spatial and temporal distribution of macrobenthic assemblages in the San Francisco Estuary and Sacramento-San Joaquin River Delta were identified using hierarchical cluster analysis of 501 samples collected between 1994 and 2008. Five benthic assemblages were identified that were distributed primarily along the salinity gradient: (1) a polyhaline assemblage that inhabits the Central Bay, (2) a mesohaline assemblage that inhabits South Bay and San Pablo Bay, (3) a low-diversity oligohaline assemblage primarily in Suisun Bay, (4) a low-diversity sand assemblage that occurs at various locations throughout the Estuary, and (5) a tidal freshwater assemblage in the Delta. Most sites were classified within the same assemblage in different seasons and years, but a few sites switched assemblage designations in response to seasonal changes in salinity from freshwater inflows.

Spatial trends and impairment assessment of mercury in sport fish in the Sacramento-San Joaquin Delta watershed.

A three-year study was conducted to examine mercury in sport fish from the Sacramento-San Joaquin Delta. More than 4000 fish from 31 species were collected and analyzed for total mercury in individual muscle filets. Largemouth bass and striped bass were the most contaminated, averaging 0.
