Impact of Telemedicine Versus In-Person Pediatric Outpatient Type 1 Diabetes Visits on Immediate Glycemic Control: Retrospective Chart Review.

Background: Children and adolescents with type 1 diabetes require frequent outpatient evaluation to assess glucose trends, modify insulin doses, and screen for comorbidities. Continuous glucose monitoring (CGM) provides a detailed glycemic control assessment. Telemedicine has been increasingly used since the COVID-19 pandemic.

Two Cases of Thyroiditis in Adolescents Following COVID-19 Vaccinations.

With the onset of the COVID-19 pandemic and the development of widespread vaccination strategies, there have been case reports in the adult literature suggesting an increase in thyroiditis after COVID-19 vaccination. We herein describe 2 children who presented with thyroiditis after COVID-19 vaccination. Two children who received Pfizer-BioNTech COVID-19 messenger RNA vaccines later developed symptoms of thyroid hyperactivity, had positive thyroid-stimulating immunoglobulin (TSI) levels and received treatment directed toward Graves disease.

β-Silyloxy Allylboronate Esters through an Aldehyde Borylation/Homologation Sequence.

The areas of carbonyl borylation and the homologation of carbon-boron bonds have provided a number of fruitful methods in organic synthesis. Combining these approaches, the homologation of α-oxyboronate esters, provides pathways to access complex organoboronate esters stereoselectively. To this end, the homologation of α-silyloxyboronate esters with lithiated allyl chlorides to form β-silyloxy allylboronate esters is reported.

Synthesis of Biaryl Ethers by the Copper-Catalyzed Chan-Evans-Lam Etherification from Benzylic Amine Boronate Esters.

The copper-catalyzed etherification of ortho-borylated benzylic amines with phenols has been achieved to provide biaryl ethers that are prevalent in biologically active compounds. A variety of substitution patterns on the aryl boronate ester and the phenol are tolerated under the reaction conditions, providing moderate to high yields. A competition reaction between phenol and aniline revealed condition-dependent selectivity in which the phenol could be highly favored over the aniline.

Facile formation of β-hydroxyboronate esters by a Cu-catalyzed diboration/Matteson homologation sequence.

The copper-catalyzed diboration of aldehydes was used in conjunction with the Matteson homologation, providing the efficient synthesis of β-hydroxyboronate esters. The oxygen-bound boronate ester was found to play a key role in mediating the homologation reaction, which was compared to the α-hydroxyboronate ester (isolated hydrolysis product). The synthetic utility of the diboration/homologation sequence was demonstrated through the oxidation of one product to provide a 1,2-diol.

[State-dependent motivational interviewing for people with schizophrenia and substance use: results of a randomised controlled trial].

Background: Comorbid substance use disorder in patients with schizophrenia is associated with poor clinical and social outcome and low compliance with integrated outpatient treatment programs. For the first time the present trial compares the efficacy of four sessions of motivational interviewing (MI) and four sessions of supportive therapy (ST). The primary outcome was compliance with integrated outpatient treatment post-intervention.

Early onset of obsessive-compulsive disorder and associated comorbidity.

Background: Previous studies have aimed to identify subtypes of obsessive-compulsive disorder (OCD) based on their age of onset (AOO). Obsessive-compulsive spectrum disorders (OCS disorders) such as tic disorders have been particularly associated with an early onset in some studies. However, subtypes of early- and late-onset OCD are unevenly determined, and the biological and the clinical validity of these subtypes are unknown.

[Motivational interviewing for patients with comorbid schizophrenia and substance abuse disorders: a review].

Patients with schizophrenia and substance abuse disorders [dually diagnosed patients (DD)] show an unfavourable course of the illness and little interest in participating on specific integrated treatment programmes. Motivational interviewing (MI) has been shown to be effective among other substance abuse disorders and it aims to enhance intrinsic motivation to change problem behaviour. MI has been adapted for DD.

The nonresilient hybrid removable prosthesis: treatment of choice for the atrophic maxilla.

This article presents the ments of the nonresilient hybrid removable prosthesis, which is the treatment of choice for the atrophic maxilla. The technique described may be adapted to yield a predictable outcome that provides functional and biomechanical stability that are superior to a resilient over-denture, along with a cosmetic and phonetic result that often proves superior to that of the fixed prosthesis.

Development of human cochlear active mechanism asymmetry: involvement of the medial olivocochlear system?

To study the functional development of the medial olivocochlear system, transient-evoked otoacoustic emission suppression experiments were conducted in 73 ears of 38 pre-term and 11 full-term neonates. The continuous contralateral stimulation was a broad band white noise, presented at 70 dB SPL. Efferent suppression was determined by subtracting the without-contralateral stimulation condition from the with-contralateral stimulation condition.

Development of cochlear active mechanisms in humans differs between gender.

Despite onset of function early during the third term of gestation, the human auditory system demonstrates continued maturation, thought previously to occur primarily at the neural level. The electromotile properties of outer hair cells appear to contribute substantially to hearing sensitivity and frequency selectivity and lead to the generation of otoacoustic emissions (OAEs). This report demonstrates continued development of cochlear active mechanisms (i.

Effect of nitric oxide blockade on the lower limit of the cortical cerebral autoregulation in pentobarbital-anaesthetized rats.

The role of nitric oxide (NO) in cerebral autoregulation is controversial. The purpose of this study was to compare the effects on the lower limit of the cortical cerebral autoregulation of the inhibition of NO synthesis by N omega-nitro-L-arginine (L-NNA) infusion to saline and phenylephrine in pentobarbital-anaesthetized rats. Variations of the cortical cerebral blood flow (CBF), the cortical cerebrovascular resistances, the mean arterial pressure and the lower limit of cerebral autoregulation were compared in three groups: a group pretreated with L-NNA (n = 8), a group pretreated with saline (n = 8) and a group pretreated with phenylephrine (n = 5).

Spontaneous otoacoustic emissions in preterm neonates: prevalence and gender effects.

A number of lines of evidence indicate that the human cochlea is fully functional as a mature sound transducer by 6 months of age. However, information about the development of the active cochlear mechanisms and notably the development of outer hair cell (OHC) activity is yet incomplete. Recording and analysis of otoacoustic emissions (OAEs), probably generated by the OHCs of the organ of Corti, have led to a better understanding, in humans, of how sounds are analysed in the cochlea by means of active mechanisms.

Factors related to sleep apnea syndrome in sleep clinic patients.

We examined 129 patients recruited from two sleep clinics to study the sleep apnea syndrome (SAS), defined by the apnea-hypopnea index (AHI) > or = 10. Information was registered from a self-administered questionnaire, basal physical measurements, and polysomnography. In 68 subjects recorded for two consecutive nights, a high correlation was found between first- and second-night AHIs (r = 0.

Lack of association between transiently evoked otoacoustic emission amplitude and experimentation linked-factors (repeated acoustic stimulation, cerebrospinal fluid pressure, supine and sitting positions, alertness level).

Changes in transiently evoked otoacoustic emissions (TEOAEs) occur during sleep and during tasks requiring attention. This can be due to a central nervous system effect on the cochlea. But, an additional or dominant influence by non-controlled factors is possible.

Effect of sleep stages on transiently evoked oto-acoustic emissions in infants.

Transiently evoked oto-acoustic emissions (TEOAEs) are generated by active contractions of the outer hair cells (OHC) of the organ of Corti. TEOAE are inhibited by the medial efferent olivocochlear system which originates in the brainstem and innervates the OHC. TEOAEs are a rapid non-invasive objective method of auditory screening in infants.

[Depressive symptomatology and sleep apnea syndrome].

The sleep apnea syndrome (SAS), which is defined by more than 5 apneas or hypopneas per hour of sleep (9), is quite a frequent affection which concerns 1.4 to 10% of general population (1.7).

Naltrexone improves blood gas patterns in obstructive sleep apnoea syndrome through its influence on sleep.

Endogenous opiates have been shown to depress ventilation, and could therefore play a role in sleep apnoea syndrome (SAS). Hence, opiate antagonists have been used to treat SAS. The improvement they seem to give in blood-gas monitoring could derive either from a direct blocking of endorphins that inhibit respiration or else, indirectly, through an influence on sleep patterns.

Brainstem auditory evoked potentials following meningitis in children.

The report concerns findings for brainstem auditory evoked potentials (BAEPs) recorded in 116 children, aged between a few days and 7 years, having suffered from bacterial meningitis. 26% of cases occurred between birth and 6 months, 55% between 6 months and 2 years, and 19% after 2 years of age. Hemophilus was the most common bacteria (49%), followed by Pneumococcus (22%) and Meningococcus (15%).

[Sleep apnea syndrome: psychiatric aspects].

The prognosis of sleep apnea syndrome (SAS) is dominated by cardiovascular complications. However, this disease is concerned with psychiatric field through specific clinical patterns. Nocturnal respiratory arrests are responsible for hypoxic and hypercapnic events including sleep fragmentation, reduction of slow wave sleep and rapid eye movement sleep.

[Sleep disorders with nocturnal bradycardia in 2 depressed patients].

Polygraphic sleep exploration is usually not necessary to evaluate and treat such dyssomnias as nightmares or anguish dreams, but it may be indispensable in case of severe repeated or refractory sleep disorders, particularly in patients with concomitant depression. Two cases of major depression (DSM III R) associated with wakings during the night and dreams of death are reported. In both cases, polygraphic sleep exploration performed after complete, two-weeks long discontinuation of medicines revealed sinus bradycardia during paradoxical sleep, particularly in pre-waking periods.

Increased serotonin platelet uptake after tianeptine administration in depressed patients.

Tianeptine is a new antidepressant drug reported to enhance serotonin (5-hydroxytryptamine [5-HT]) uptake in rat brain. The effect of tianeptine on 5-HT platelet uptake was studied in 10 depressed patients treated for 28 days. Tianeptine increases Vmax of 5-HT platelet uptake during treatment without inducing any change in Km.

Optimization of hybrid composite properties.

Hybrid composites have been a popular class of a wear-resistant posterior composite restorative material. The purpose of this study was to determine the effect of hybridization on the physical properties of a composite with different amounts of submicron silica (0.04 microns) with semiporous strontium glass (1.
