To address the remaining issue of poor cell immobilization and insufficient mass transfer in scaffold-based tissue engineering approach for future islet transplantation, we employed a macro-porous poly-l-lactide (PLLA) scaffold immobilizing mouse insulinoma cells and studied its function toward an implantable pancreatic tissue in 7-day perfusion culture. The murine pancreatic β cells could be immobilized in the PLLA scaffold at a high density of 107 cells per cm3 close to the estimated range in normal pancreas. The perfusion culture promoted the 3D cellular organization as observed with live/dead staining and histological staining. The insulin production was significantly enhanced in comparison with static 2D culture and 3D rotational suspension culture by two and six folds, respectively (p  less then  0.001). As enhanced insulin response was only observed where both the perfusion and 3D cellular organization were present, this could represent important elements in engineering a functional bioartificial pancreas.The purpose of this study was to explore users' perspectives on power wheelchair service delivery and understand their involvement in the equipment trial and selection process. Five power wheelchair users participated in. Responses and interview data analysis supported four main themes describing variability in the evaluation practices of the provider team, how consumers' participation goals were impacted by equipment usability, consumer involvement in equipment selection influenced satisfaction, and illustrated the complexities in the service delivery process. The conclusion suggests consumer involvement in the trial and selection process may contribute to power wheelchair outcome usability, satisfaction, and occupational engagement.
Various intravenous (IV) corticosteroids are available for acute severe asthma (ASA) treatment. The choice of IV corticosteroids varies broadly and depends on institution, country, or physician preferences. In this study, we compared the efficacy of IV methylprednisolone, hydrocortisone and dexamethasone in ASA treatment during pediatric intensive care unit (PICU) admission.

The study was a prospective randomized clinical trial. We enrolled patients of 1-21 years after they were admitted to the PICU requiring continuous beta-2 agonist treatment. Patients were randomized into three groups Group A IV Methylprednisolone, Group B IV Hydrocortisone and Group C IV Dexamethasone. The primary outcomes measured were durations of beta-2 agonist continuous nebulization treatment. Secondary outcomes, included PICU and hospital length of stay (LOS), pediatric asthma severity score (PASS), need for mechanical ventilation and maximum dose of beta-2 agonist treatment.

61 patients were included in the analysis. 22 patients recruited in Group A, 20 in group B and 19 group C. Median durations of beta-2-agonist treatment were 23 h (QR 16-38) for methylprednisolone, 27 h (QR 16-40) for hydrocortisone, and 32 h (QR 16-48) for dexamethasone (
 = 0.90). There was no difference in PICU LOS, hospital LOS, PASS score, B2 agonist maximum dose, or need for ventilation support.

The use of IV methylprednisolone, hydrocortisone, and dexamethasone have equivalent efficacy when used at the appropriate doses. Studies with larger cohorts are needed to compare the effectiveness of IV corticosteroids in the management of ASA in the PICU setting.

A systematic approach utilizing 'quick hit' experiments demonstrated variability introduced into culture systems resulting from slight changes to culture conditions (route A). This formed the basis for longitudinal experiments investigating long-term effects of culture parameters including seeding density and feeding regime (route B).Results demonstrated that specific growth rates (SGR) of passage 59 (P59) cells seeded at 20,000 cells/cm2 and subjected to medium exchange after 48h prior to reseeding at 72h (route B2) on average was marginally higher than, P55 cells cultured under equivalent conditions (route A1); whereby SGR values were (0.021±0.004) and (0.019±0.004). Viability was higher in route B2 over 10 passages with average viability reported as (86.3%±8.1) compared to route A1 (83.3±8.8). AZD1390 The metabolite data demonstrated both culture route B1 (P57 cells seeded at 66,667 cells/cm2) and B2 had consistent-specific metabolite rates (SMR) for glucose, but SMR values of route B1 was consistently lower than route B2 (0.00001 mmol, cell-1.d-1 and 0.000025).Results revealed interactions between phenotype, SMR and feeding regime that may not be accurately reflected by growth rate or observed morphology. This implies that current schemes of protocol control do not adequately account for variability, since key cell characteristics, including phenotype and SMR, change regardless of standardized seeding densities. This highlights the need to control culture parameters through defined protocols, for processes that involve culture for therapeutic use, biologics production, and reference lines.
Objective of the present manuscript is to investigate, among Italian early career psychiatrists (ECPs), prescriber and patient-related factors associated with lithium or valproate preference to treat patients affected by Bipolar Disorder (BD).

An on-line survey was carried out among 252 ECPs, investigating their prescription patterns in relation to lithium and the differences with prescription of valproate. Collected data were compared according to lithium or valproate prescription preference in the long-term treatment of BD by

tests for qualitative variables.

Over two thirds of ECPs preferred lithium over valproate for the maintenance treatment of BD. Less than half of the sample used lithium as first-line agent for mania or major depression, and less than one third for mixed episodes. Factors associated with lithium preference as first-line maintenance treatment include perception of having a good knowledge of lithium (
 < 0.001) and complete satisfaction with education on lithium (
 < 0.long-term treatment of Bipolar Disorder.Educational and clinical factors seem to influence the attitude to prescribe lithium.Only half of the Italian early career psychiatrists declare to have at least an adequate knowledge of lithium.Residency program in psychiatry should consider the implementation of education on lithium.Introduction With the ongoing SARS-CoV-2 pandemic, different articles have been published highlighting the superiority of droplet digital PCR (ddPCR) over the gold-standard reverse transcription PCR (RT-PCR) in SARS-CoV-2 detection. However, few studies have been reported on developing multiplex ddPCR assays for SARS-CoV-2 detection and their performance. This study shows steps on how to develop different ddPCR SAR-CoV-2 assays including higher order multiplex assays for SARS-CoV-2 detection and antiviral screening.Methods Using multiple primer/probe sets, we developed, optimized, and analyzed the performance of simplex (1 target), duplex (2 targets), triplex probe mix (3 targets), and quadruplex (4 targets) SARS-CoV-2 ddPCR assays based on a two-color ddPCR detection system.Results Results showed that the quadruplex assay had similar limits of detection and accuracy to the lower multiplex assays. Analyzing 94 clinical samples demonstrated that the ddPCR triplex probe mix assay had better sensitivity than the RT-qPCR assay. Additionally, the ddPCR multiplex assay showed that remdesivir could inhibit the growth of SARS-CoV-2 in vitro while another testing drug could not.Conclusion Our research shows that developing multiplex ddPCR assays is possible by combing probe mix and amplitude-based multiplexing, which will help in developing multiplexed ddPCR assays for different SARS-CoV-2 applications.Fenretinide (4-HPR), a synthetic retinoid, has attracted attention for its anti-inflammation activity. However, few studies have evaluated the effects of 4-HPR on ulcerative colitis (UC). The present study was performed to investigate the therapeutic effects of 4-HPR on UC, and to explore the mechanisms mainly focused on macrophage polarization involved in this progress. Intraperitoneally administered 4-HPR particularly at dose of 100 mg/kg obviously alleviated UC symptoms and restrained the mRNA expression of colonic IL-1β, IL-6, and TNF-α in dextran sulfate sodium (DSS)-induced mice. Further analysis showed that 4-HPR decreased the mRNA expression of M1 macrophage markers IL-12 and iNOS, while increased M2 macrophage markers Ym1, Arg1 and MRC1 in colonic tissue of mice received DSS. Consistently, an in vitro study revealed that 4-HPR decreased inflammatory response and M1 polarization, while enhanced M2 polarization in LPS-induced RAW264.7 cells. Interestingly, 4-HPR remarkably activated PPAR-γ which was an important regulator of macrophage polarization both in colonic tissue of UC mice and in LPS-induced RAW264.7 cells. Furthermore, these effects of 4-HPR in vivo and in vitro including anti-inflammation and modulation of macrophage polarization were partially abolished by treatment with PPAR-γ antagonist GW9662, indicating that 4-HPR activated PPAR-γ to exert its activities. Taken together, this study demonstrated that 4-HPR might be a potent anti-UC agent that works by regulating macrophage polarization via PPARγ.Introduction Substance use peaks during the transition to adulthood, beckoning additional research on its developmental influences. This article reports initial findings on the validity and reliability of the Emerging Adult Reasons for Substance use (EARS), a new measure of substance use motives based on Arnett's (2000) proposed emerging adult dimensions. Method Content experts in emerging adulthood theory generated EARS items and collected data from a large online sample. We completed exploratory (EFA) and confirmatory factor analyses (CFA) on split halves of the total sample (n = 750). Then, we tested for invariance across genders and age cohorts, as well as examined cross-correlations with the Inventory of Dimensions of Emerging Adulthood (IDEA), Drinking Motives Questionnaire (DMQ-Revised), and measures of substance use. Results The EFA identified three internally consistent factors Normative Expectancy, Developmental Strain, and Subjective Invulnerability. Confirmatory factor analyses supported the three factor model, but fit indices were slightly below published standards (RSMEA = .82, CFI = .85, TLI = .83, SRMR = .07). For Normative Expectancy and Developmental Strain, intercepts varied across age cohorts, with higher intercepts for emerging relative to older adults. The patterns of correlations generally supported the construct validity of the EARS subscales. Conclusion The EARS is reliable and valid, and appears to measure developmentally specific motives for substance use. Additional studies may further validate this promising instrument.
