Microneedle (MN)-based technologies are currently one of the most innovative approaches that are being extensively investigated for transdermal delivery of low molecular weight drugs, biotherapeutic agents and vaccines. Extensive research reports, describing the fabrication and applications of different types of MNs, can be readily found in the literature. Effective characterization tools to evaluate the quality and performance of the MNs as well as for determination of the dimensional and kinetic properties of the microchannels created in the skin, are an essential and critical part of MN-based research. This review paper provides a comprehensive account of all such tools and techniques.Aim To evaluate toxicity risk in carriers of four DPYD variants using an institutional genetic repository. Materials & methods Of over 65,000 patients in the repository, 582 were evaluated for the primary composite end point of grade 3 or higher toxicity or treatment modification due to toxicity. Results The primary end point was more common in DPYD variant carriers (36.5 vs 18.1%, adjusted odds ratio 2.42, 95% CI 1.05-5.55, p = 0.04), and in patients with decreased DPD activity (≤1 vs 2) (75.6 vs 17.0%, adjusted odds ratio 16.31, 95% CI 2.64-100.68, p = 0.003). Conclusion Patients carrying any of the four DPYD variants are at increased risk of severe toxicity or subsequent treatment modifications, suggesting such patients may benefit from genotype-informed treatment.In the present study, the chemical compositions of the essential oils from roots, stems, leaves and fruits of Foeniculum vulgare subsp. piperitum collected in Sicily were evaluated by GC and GC-MS. Blebbistatin mw The main components of the roots were terpinolene (33.15%), γ-terpinene (12.18%) and fenchyl acetate (11.23%). Stems and leaves were very rich in α-phellandrene (36.85% and 41.59%, respectively) and β-phellandrene (19.68% and 25.79%, respectively), whereas the main components of fruits were terpinolene (20.10%) and limonene (17.84%)These results were compared with those of the EOs of the same vegetative parts of Foeniculum vulgare subsp. vulgare, collected in the same station and in the same days. The oils of F. vulgare subsp. vulgare showed completely different compositions, with estragole, (E)-anethole and α-pinene as main compounds, clearly indicating the differentiation of the two subspecies. Our results were also compared with those reported in literature for other accessions of Foeniculum vulgare subsp. piperitum.Background Short ECG P-wave duration has recently been demonstrated to be associated with higher risk of atrial fibrillation (AF). The aim of this study was to assess the rate of AF recurrence after pulmonary vein isolation in patients with a short P wave, and to mechanistically elucidate the observation by computer modeling. Methods and Results A total of 282 consecutive patients undergoing a first single-pulmonary vein isolation procedure for paroxysmal or persistent AF were included. Computational models studied the effect of adenosine and sodium conductance on action potential duration and P-wave duration (PWD). About 16% of the patients had a PWD of 110 ms or shorter (median PWD 126 ms, interquartile range, 115 ms-138 ms; range, 71 ms-180 ms). At Cox regression, PWD was significantly associated with AF recurrence (P=0.012). Patients with a PWD less then 110 ms (hazard ratio [HR], 2.20; 95% CI, 1.24-3.88; P=0.007) and patients with a PWD ≥140 (HR, 1.87, 95% CI, 1.06-3.30; P=0.031) had a nearly 2-fold increase in risk with respect to the other group. In the computational model, adenosine yielded a significant reduction of action potential duration 90 (52%) and PWD (7%). An increased sodium conductance (up to 200%) was robustly accompanied by an increase in conduction velocity (26%), a reduction in action potential duration 90 (28%), and PWD (22%). Conclusions One out of 5 patients referred for pulmonary vein isolation has a short PWD which was associated with a higher rate of AF after the index procedure. Computer simulations suggest that shortening of atrial action potential duration leading to a faster atrial conduction may be the cause of this clinical observation.Objective/Background While cognitive-behavioral therapy for insomnia (CBT-I) is typically delivered over six-eight sessions, the field has introduced ever briefer versions. We examined session by session effects on both insomnia and depression outcomes in a brief, four-session version of CBT-I.Participants This is a secondary analysis of data drawn from participants randomized to brief cognitive behavioral therapy for insomnia (bCBTi) in a pilot clinical trial. All participants (n = 19) were veterans enrolled in primary care who screened positive for insomnia and co-occurring PTSD and/or depression.Methods Participants received four, weekly, individual sessions of bCBTi during which they provided self-report data on insomnia, depression, and sleep parameters over the preceding week. Baseline and follow-up assessments were also collected.Results Changes in insomnia and depression severity between baseline and the beginning of session one were non-significant. Statistically significant decreases were observed, however, for insomnia severity between sessions one to two (g = -.65) and sessions two to three (g = -.59). This pattern was mirrored for depression severity with significant decreases between sessions one and two (g = -.65) and sessions two to three (g = -.68). However, there was little change for either outcome from session three to session four (insomnia g = -.16; depression g = -.14).Conclusions This session by session analyses of bCBTi revealed that the majority of the treatment effect occurred over the first two sessions. Findings suggest that even brief interventions addressing insomnia may have a positive impact on both insomnia and co-occurring depression.This study aimed to examine the associations between perceived coronavirus risk, coronavirus fear, mental well-being and parental coronavirus anxiety, as well as the mediating role of coronavirus fear and moderating role of mental well-being.The sample comprised 189 healthcare workers (M = 33.06 ± 6.92), who were treating patients with COVID-19 in a pandemic hospital in Turkey. Ninety-one participants were males and 98 females. Participants completed measures of perceived coronavirus risk, coronavirus fear, mental well-being and parental coronavirus anxiety.Parental Coronavirus Anxiety Scale had a one-factor structure, with satisfactory reliability. Main findings showed that coronavirus fear mediated the relationship between coronavirus risk and parental coronavirus anxiety. Mental well-being moderated the effect of coronavirus risk on parental coronavirus anxiety. The mediation effect of coronavirus fear was moderated by mental well-being.These findings explain why and when mental well-being-based interventions could be effective in reducing perceived coronavirus risk, fear and parental coronavirus anxiety about their children.
