We have previously demonstrated that ascorbic acid (AsA) deficiency causes inflammatory changes in the liver and intestine in Osteogenic Disorder Shionogi (ODS) rats, which are unable to synthesize AsA. We have suggested that AsA deficiency increased intestinal interleukine (IL)-6 production, stimulating hepatic acute phase proteins (APPs) expression via the portal vein. In this study, we determined whether these hepatic and intestinal inflammatory changes by AsA deficiency are induced in germ-free (GF) ODS rats. For 18 days, male specific pathogen-free (SPF) ODS rats were fed the basal diet containing 600 mg AsA/kg (control group) or the AsA-free diet (AsA-deficient group) in SPF conditions, while male GF ODS rats were fed the basal diet (control group) or the AsA-free diet (AsA-deficient group) in GF conditions. Firstly, AsA deficiency significantly elevated the hepatic expression of APPs in both SPF and GF rats. In hepatic mRNA levels of some APPs, significant interaction between GF and AsA-deficiency effects was observed. Secondly, AsA deficiency elevated intestinal IL-6 and IL-1β mRNA levels in both SPF and GF rats, and significant interaction between GF and AsA-deficiency effects was observed in these mRNA levels of jejunum and cecum. In SPF and GF rats, AsA deficiency elevated portal IL-6 concentration. These results show that AsA deficiency caused hepatic and intestinal inflammatory changes in both the GF and SPF ODS rats and indicate that AsA deficiency could directly induce intestinal inflammatory changes without the involvement of gut microbiota.We report the optimisation of a series of novel amide-piperidine (piperazine) derivatives using the multiple ligand approach with dopamine and serotonin receptors. Of the derivatives, compound 11 exhibited high affinity for the D2, 5-HT1A, and 5-HT2A receptors, but low affinity for the 5-HT2C and histamine H1 receptors and human ether-a-go-go-related gene (hERG) channels. In vivo, compound 11 reduced apomorphine-induced climbing, MK-801-induced hyperactivity and DOI-induced head twitching without observable catalepsy, even at the highest dose tested. In addition, it exhibited suppression in a CAR test. Furthermore, in a novel object recognition task, it displayed procognition properties. Therefore, compound 11 is a promising candidate multi-target antipsychotic.

To evaluate and refine a newly proposed factor structure for the Adherence Barriers to Continuous Positive Airway Pressure Questionnaire (ABCQ) and to present psychometric data from a large, geographically diverse sample of children and young adults with sleep disordered breathing (SDB) treated with positive airway pressure (PAP).

A sample of 181 patients prescribed PAP for treatment of SDB, ages 8-21 years, and caregivers (n=234) of patients ages 2-21 years, completed the ABCQ during routine sleep medicine clinic visits. Adherence data from participants' PAP machines were obtained via electronic download, providing objective data on PAP adherence immediately preceding the clinic visit during which the ABCQ was completed.

A three-factor structure (1. Behavior, Beliefs, Environment, 2. Emotional Barriers, & 3. Physical Barriers) exhibited good model fit in confirmatory factor analysis. Results indicate that the ABCQ has strong psychometric properties, including good internal consistency among subscales and strong convergent validity with objectively measured PAP adherence. Analysis of the Receiver Operator Characteristic Curve (ROC) yielded an ABCQ total cut-off score of 46.5 for patient report and 53.5 for caregiver report. Scores above the cutpoint predicted nonadherence to PAP, defined as failure to use PAP for ≥4h on 70% of nights.

The three-factor ABCQ appears to be a useful patient- and caregiver-report instrument to measure barriers to PAP treatment in children and young adults with sleep disordered breathing.

This study aimed to evaluate the prognosis of COVID-19 patients in Reunion Island, with a particular focus on the management of patients with hypoxemic pneumonia.

This retrospective observational study was conducted from 11 March to 17 April 2020 at the only hospital authorized to manage patients with COVID-19 in Reunion Island.

Over the study period, 164 out of 398 patients (41.2%) infected with COVID-19 were admitted to Félix Guyon University Hospital. Of these, 36 (22%) developed hypoxemic pneumonia. Patients with hypoxemic pneumonia were aged 66 [56-77] years, 69% were male and 33% had hypertension. Ten patients (27.8%) were hospitalized in intensive care unit (ICU). Hydroxychloroquine/azithromycin treatment was associated with a lower ICU admission rate (P=0.008). None of the 6 patients treated with corticosteroids were hospitalized in ICU (P=0.16). There were no deaths at follow up (minimum 80 days).

Despite the risk profile of COVID-19 patients with severe hypoxemic pneumonia, the mortality rate of the disease in Reunion Island was 0%. Linifanib in vitro This may be due to the care bundle used in our hospital (early hospitalisation, treatment with hydroxychloroquine/azithromycin and/or corticosteroids, non-invasive respiratory support, etc).

The synthesis process of the FITC grafted GG (GG-F) and manufacturing method of GG-F scaffolds are presented. Chemical, physicochemical, and mechanical properties were characterized. In vitro study and in vivo study by implanting the GG-F scaffolds under the subcutaneous area of the nude mice were carried out to verify biocompatibility and safety of the material. The emission of the FITC was confirmed with high-resolution confocal laser scanning microscope (SR CLMS) and fluorescence in vivo imaging (FOBI). The results exhibited well-synthesized GG-F and the manufactured GG-F scaffolds showed similar property of GG scaffolds which confirms that the chemical modification does not affect the property of GG scaffolds. The in vitro and in vivo study exhibited biocompatibility of the GG-F material. Overall, the properly blended GG-F in GG did not influence the characteristics of the pristine GG except for the chemical property.
