Production of C20, C30 and C40 terpenes inside the designed phototrophic bacterium Rhodobacter capsulatus.
A 35-year-old woman with a history of cocaine abuse presented with progressively worsening OS pain. Neuroimaging revealed a 3-cm ill-defined left orbital lesion involving the intraconal and extraconal spaces. The orbital mass was biopsied via an anterior orbitotomy approach. Pathology demonstrated prominent angiocentric granulomatous and lymphoplasmacytic inflammation consistent with vasculitis. SM04690 clinical trial Laboratory tests were significant for neutropenia, positive perinuclear antineutrophil cytoplasmic antibodies with high titer, and positive myeloperoxidase antibodies, consistent with levamisole-induced vasculitis. To the authors' knowledge, this is the first reported case of cocaine-levamisole-induced vasculitis presenting as orbitopathy.INTRODUCTION The floppy eyelid syndrome describes an eyelid disorder characterized by floppy tarsal plates that may be caused by a loss of elastin. The authors attempted to create floppy eyelids by digesting elastin from cadaveric tarsus and then treated them with cross-linking using ultraviolet A and riboflavin. METHODS Nine right and 9 left upper eyelids were excised from cadavers. Four vertical strips of central tarsus were removed from each eyelid. One strip of tarsus from each eyelid was treated with 10 units/ml of elastase for 2 hours. Another tarsal strip from each eyelid was immersed in normal saline for 2 hours (control). A third strip from the same eyelid was cross-linked using ultraviolet A at 6 mW/cm for 18 minutes. Finally, a fourth strip of tarsus was cross-linked in the same manner following treatment with elastase for 2 hours. A microtensile load cell was used to measure the Young modulus (stiffness) of each tissue. RESULTS Mean (standard deviation) Young modulus for controls (18.9 ± 3.6 MPa) was significantly higher than samples treated with elastase alone (6.6 ± 3.8 MPa, p less then 0.01). Samples that were treated with cross-linking after elastase had a mean (standard deviation) Young modulus of 26 ± 2.3 MPa, while those treated with cross-linking alone had a mean (standard deviation) Young modulus of 34 ± 0.15 MPa. The differences in stiffness between all groups were significant (p less then 0.01). DISCUSSION Treatment with elastase significantly reduces the stiffness of tarsal plates. This effect is reversed by cross-linking, raising the possibility of using this modality for the treatment of FES.BACKGROUND Health care access increased for low-income Americans under the Affordable Care Act (ACA). It is unknown whether these changes in access were associated with improved self-reported health. OBJECTIVE Determine changes in health care access, health behaviors, and self-reported health among low-income Americans over the first 4 years of the ACA, stratified by state Medicaid expansion status. DESIGN Interrupted time series and difference-in-differences analysis. SUBJECTS Noninstitutionalized US adults (18-64 y) in low income households ( less then 138% federal poverty level) interviewed in the Behavioral Risk Factor Surveillance System 2011-2017 (N=505,824). MEASURES Self-reported insurance coverage, access to a primary care physician, avoided care due to cost; self-reported general health, days of poor physical health, days of poor mental health days, and days when poor health limited usual activities; self-reported health behaviors, use of preventive services, and diagnoses. RESULTS Despite increases in access, the ACA was not associated with improved physical or general health among low-income adults during the first 4 years of implementation. However, Medicaid expansion was associated with fewer days spent in poor mental health (-1.1 d/mo, 95% confidence interval -2.1 to -0.5). There were significant changes in specific health behaviors, preventive service use, and diagnosis patterns during the same time period which may mediate the relationship between the ACA rollout and self-reported health. CONCLUSION In nationally-representative survey data, we observed improvements in mental but not physical self-reported health among low-income Americans after 4 years of full ACA implementation.OBJECTIVE An updated version of the SF-6D Classification System (SF-6Dv2) has been developed, and utility value sets are required. The aim of this study was to test the development of a United Kingdom SF-6Dv2 value set, and address limitations of the existing SF-6D value set (which results in a narrow range of utilities). This was done using 2 discrete-choice experiment (DCE) tasks. Interactions and preference heterogeneity were also investigated. RESEARCH DESIGN AND SUBJECTS An online sample of respondents (n=3014) completed 10 DCE with duration choice sets from an efficient design of 300 (Design 1) and 2 DCE with duration choice sets including immediate death from a set of 60 (Design 2). Conditional logit regression was used to estimate value set models with and without interactions. We investigated preference heterogeneity using latent class models. RESULTS Models including ordered coefficients within each dimension were developed, with the favored model including an additional interaction term when one dimension was at the most severe level. Value sets differed across Designs 1 and 2. Design 1 models had a wider utility range and a higher proportion of negative values. The most important dimensions were pain, mental health, and physical functioning. Preference heterogeneity was apparent, with a 2-class model describing the data. CONCLUSIONS We developed and applied a protocol to value the SF-6Dv2 using DCE. The results provide a provisional value set for use in resource allocation. The protocol can be applied internationally. Further work should investigate how to account for preference heterogeneity in value set production.BACKGROUND Rapid sequence induction (RSI) is a standard procedure, which should be implemented in all patients with a risk of aspiration/regurgitation during anaesthesia induction. OBJECTIVE The primary aim was to evaluate clinical practice in RSI, both in adult and paediatric populations. DESIGN Online survey. SETTINGS A total of 56 countries. PARTICIPANTS Members of the European Society of Anaesthesiology. MAIN OUTCOME MEASURES The aim was to identify and describe the actual clinical practice of RSI related to general anaesthesia. RESULTS From the 1921 respondents, 76.5% (n=1469) were qualified anaesthesiologists. When anaesthetising adults, the majority (61.7%, n=1081) of the respondents preoxygenated patients with 100% O2 for 3 min and 65.9% (n=1155) administered opioids during RSI. The Sellick manoeuvre was used by 38.5% (n=675) and was not used by 37.4% (n=656) of respondents. First-line medications for a haemodynamically stable adult patient were propofol (90.6%, n=1571) and suxamethonium (56.0%, n=932). Manual ventilation (inspiratory pressure less then 12 cmH2O) was used in 35.5% (n=622) of respondents. In the majority of paediatric patients, 3 min of preoxygenation (56.6%, n=817) and opioids (54.9%, n=797) were administered. The Sellick manoeuvre and manual ventilation (inspiratory pressure less then 12 cmH2O) in children were used by 23.5% (n=340) and 35.9% (n=517) of respondents, respectively. First-line induction drugs for a haemodynamically stable child were propofol (82.8%, n=1153) and rocuronium (54.7%, n=741). CONCLUSION We found significant heterogeneity in the daily clinical practice of RSI. For patient safety, our findings emphasise the need for international RSI guidelines.TRIAL REGISTRATION ClinicalTrials.gov identifier NCT03694860.BACKGROUND The prevalence of prediabetes and diabetes is increasing rapidly, and 5% to 10% of prediabetic patients will develop diabetes every year. Diabetes causes major health problems as well as a large economic burden. Human studies have demonstrated the beneficial effects of probiotics, prebiotics, and synbiotics supplementation in prediabetes. However, there are no systematic reviews that explore the therapeutic efficacy of probiotics, prebiotics, and synbiotics supplementation in patients with prediabetes. Therefore, we aim to synthesize the existing evidence evaluating the effectiveness and safety of probiotics, prebiotics, and synbiotics supplementation in prediabetic patients. METHODS We will search PubMed, EMBASE, Cochrane Library, Web of Science, the Clinical Trials.gov website, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Data Knowledge Service Platform from inception to August 2020. Additionally, the search will be conducted in multiple languages. Search terms are keywords and medical subject headings related to prediabetes, probiotics, prebiotics, and synbiotics. The primary outcomes are differences in glycated hemoglobin and fasting blood glucose. The secondary outcomes are differences in fasting insulin, homeostasis model assessment of insulin resistance, quantitative insulin sensitivity check index, and adverse events. The meta-analysis will be performed using the Revman5.3.0 software provided by the Cochrane Collaboration. RESULTS Our study will systematically evaluate the effectiveness and safety of probiotics, prebiotics, and synbiotics supplementation in prediabetes. CONCLUSION The findings of this study will provide the best available evidence for probiotics, prebiotics, and synbiotics in the treatment of prediabetes, and provide a strong basis for clinical treatment.Chronic obstructive pulmonary disease (COPD) has a major impact on mortality and morbidity in patients undergoing cardiac surgery. Mortality risk increases by 50% in patients who were re-intubated or required prolonged mechanical ventilation after the operation. The aim of this study was to assess the impact of COPD on the prediction of postoperative complications and outcome including intensive care unit (ICU) and hospital stay, postoperative morbidity and mortality in patients undergoing all types of cardiac surgery.We performed a retrospective cohort analysis of prospectively collected data from a tertiary cardiac surgery department of a university hospital between 2014 and 2016. We divided patients undergoing cardiac surgery into 2 sub-groups - the first - with a clinical diagnosis of COPD (n = 198) and the second comprised all other non-COPD patients (n = 2980).Among patients with COPD a longer intubation time (P = .039), longer ICU stay (P  less then  .001) and longer hospitalization time (P = .006) wasaning mechanical ventilation must be employed to reduce postoperative complications.This study aims to examine the association between sleep duration and cognitive impairment in community-dwelling Chinese older adults.The associations between sleep duration and cognitive function have been widely studied across various age ranges but are of particular importance among older adults. However, there are inconsistent findings regarding the relationship between sleep duration and cognitive function in the literature.This study is an observational cross-sectional study. We analyzed data from 1115 Chinese individuals aged 60 and older from 3 Chinese communities (Beijing, Hefei, and Lanzhou). Cognitive impairment was defined as a Mini-Mental State Examination total score less than 24 points. Odds ratios (ORs) of associations were calculated and adjusted for potential confounders in logistic regression models.The prevalence of cognitive impairment was 25.7% (n = 287). Controlling for all demographic, lifestyle factors, and coexisting conditions, the adjusted OR for cognitive impairment was 2.54 (95% CI = 1.
