Background Studies on the association between the prothrombin G20210A variant and coronary artery disease (CAD) risk are inconclusive. This study aimed to investigate the possible association between the G20210A variant in the prothrombin gene and documented CAD and its severity. Methods This study enrolled 1460 patients who were consecutively admitted for elective coronary angiography. Via the standard angiographic techniques, coronary angiographies were done and the presence and severity of CAD were determined through the clinical vessel score and the Gensini score. Prothrombin G20210A genotypes were identified using PCR-RFLP. Results This cross-sectional study was performed on 953 men and 507 women at a mean age of 58.21±10.33 years. The median and the interquartile range for the Gensini score were not statistically significantly different between the wild (GG) and mutant (AA+GA) genotypes (P=0.440). The association between the G20210A polymorphism and the severity of CAD with respect to the vessel score also showed no significant linear trend of higher numbers of diseased vessels (P= 0.765 for the Mantel-Haenszel test of linear trend) in the AA+GA genotype as compared with the GG genotype. Conclusion Our data failed to confirm the hypothesis that the G20210A variant mutation may be a significant determinant of CAD risk or its severity.We describe simulations using an updated version of the Community Multiscale Air Quality model version 5.3 (CMAQ v5.3) to investigate the contribution of intermediate-volatility organic compounds (IVOCs) to secondary organic aerosol (SOA) formation in southern California during the CalNex study. We first derive a model-ready parameterization for SOA formation from IVOC emissions from mobile sources. To account for SOA formation from both diesel and gasoline sources, the parameterization has six lumped precursor species that resolve both volatility and molecular structure (aromatic versus aliphatic). We also implement new mobile-source emission profiles that quantify all IVOCs based on direct measurements. The profiles have been released in SPECIATE 5.0. By incorporating both comprehensive mobile-source emission profiles for semivolatile organic compounds (SVOCs) and IVOCs and experimentally constrained SOA yields, this CMAQ configuration best represents the contribution of mobile sources to urban and regionalas volatile chemical products.Little is known about dental practice patterns of caries prevention in adults among Brazilian dentists. Objective To quantify procedures used for caries prevention for adult patients among dentists from a Brazilian community. Methods Dentists (n=197) who reported that at least 10% of their patients are more than 18 years old participated in the first Brazilian study that used a translated version of the "Assessment of Caries Diagnosis and Caries Treatment" from the U.S. National Dental Practice-Based Research Network. A questionnaire about characteristics of their practice and patient population were also completed by the dentists. Generalized linear regression models and a hierarchal clustering procedure were used (p less then 0.05). Results In-office fluoride application was the preventive method most often reported. The main predictors for recommending some preventive agent were female dentist (dental sealant; in-office fluoride; non-prescription fluoride) and percentage of patients interested in caries prevention (dental sealant; in-office fluoride; non-prescription fluoride). Other predictors included private practice (dental sealant), percentage of patients 65 years or older (in-office fluoride), graduation from a private dental school (non-prescription fluoride), years since dental school graduation (chlorhexidine rinse) and using a preventive method (recommending sealant/fluoride/chlorhexidine rinse/sugarless, xylitol gum). Cluster analysis showed that dentists in the largest subgroup seldom used any of the preventive agents. Conclusion Dentists most often reported in-office fluoride as a method for caries prevention in adults. Some practitioner, practice and patients' characteristics were positively associated with more-frequent use of a preventive agent.Pharmacokinetic data regarding ceftaroline fosamil (CPT) penetration into cerebrospinal fluid (CSF) are limited to a rabbit model (15% inflamed) and adult case reports. We describe serum and CSF CPT concentrations in a 21-year-old, 34.8 kg female, medically complex patient presented with a 4-day history of fevers (Tmax 39.2°C), tachypnea, tachycardia, fatigue, and a 1-week history of pus and blood draining from the ventriculopleural (VPL) shunt. A head CT and an ultrasound of the neck revealed septated complex fluid collection surrounding the shunt. Therapy was initiated with vancomycin and ceftriaxone. Blood and CSF cultures from hospital day (HD) 1 were positive for methicillin-resistant Staphylococcus aureus with a CPT MIC of 0.5 mg/L and a vancomycin MIC range of 0.5 to 1 mg/L. JQ1 research buy On HD 3, CPT was added. On HD 7, simultaneous serum (69.4, 44, and 30.2 mg/L) and CSF (1.7, 2.3, and 2.3 mg/L) concentrations were obtained at 0.25, 1.5, and 4.75 hours from the end of an infusion. Based on these concentrations, CPT CSF penetration ratio ranged from 2.4% to 7.6%. After addition of CPT, the blood and CSF cultures remained negative on a regimen of vancomycin plus CPT. On HD 14, a new left-sided VPL shunt was placed. The patient continued on CPT for a period of 7 days after the new VPL shunt placement. This case demonstrated CPT CSF penetration in a range of 2.4% to 7.6%, approximately half of the rabbit model. This allowed for CSF concentrations at least 50% free time > 4 to 6× MIC of the dosing interval with a dosing regimen of 600 mg IV every 8 hours in a 34.8 kg chronic patient and resulted in a successful clinical outcome with no identified adverse outcomes.Sleep disturbance is a crucial issue in pediatric palliative care, with a dramatic impact on the quality of life of children and families. Dexmedetomidine (DEX) is a selective α-2 agonist, with anxiolytic, hypnotic, and analgesic properties, that could play a role in the management of refractory sleep disturbances. We describe the use of intranasal DEX as a sleep inductor in a 10-year-old female with dystrophic epidermolysis bullosa and a severe sleep disorder. After treatment with melatonin, benzodiazepines, and niaprazine had failed, she was admitted to the hospital where 3 mcg/kg/day of intranasal DEX was administered before bedtime. She received 0.7 mL of the IV formulation at a concentration of 100 mcg/mL with half the dose given in each nostril via a Mucosal Atomization Device. During this time, she was also monitored for potential side effects (e.g., bradycardia, blood pressure derangements). After 2 weeks of hospitalization, she was discharged with ready-to-use doses of DEX for home treatment. The child's heart rate and blood oxygen saturation were monitored at home.
