BACKGROUND Anxiety disorders are prevalent in patients with myocardial infarction (MI), but the effects of anxiety disorders on in-hospital outcomes within MI patients have not been well studied. HYPOTHESIS To examine the effects of concurrent anxiety disorders on in-hospital outcomes in MI patients. METHODS We conducted a retrospective cohort study in patients with a principal diagnosis of MI with and without anxiety disorders in the National Inpatient Sample 2016. A total of 129 305 primary hospitalizations for acute MI, 35 237 with ST-segment elevation myocardial infarction (STEMI), and 94 068 with non-ST elevation myocardial infarction (NSTEMI) were identified. Of these, 13 112 (10.1%) had anxiety (7.9% in STEMI and 11.0% in NSTEMI). We compared outcomes of anxiety and nonanxiety groups after propensity score matching for the patient and hospital demographics and relevant comorbidities. RESULTS After propensity score matching, the anxiety group had a lower incidence of in-hospital mortality (3.0% vs 4.4%, P  .05) between the matched groups. Mitoquinone CONCLUSION Although we found that anxiety was associated with better in-hospital outcomes, subgroup analysis revealed that this only applied to patients admitted for NSTEMI instead of STEMI. © 2020 The Authors.

The repeated exposure to Infrared radiations (IR) induces the heat into the skin, which causes dehydration and erythema as an immediate effect. This heat activates the Metalloproteinase enzyme that reduces the number of procollagen and collagen fibers in the dermal skin, which results premature skin aging. This work aims to design a protective measure in order to avoid these damages. METHOD The proposed protective measure is a wristwatch with an alert alarm which can sense UV and IR radiations. Whenever UV/IR radiation levels exceed beyond the defined limits, alarm will be activated that warns the user to apply protective measures. These radiations are detected by SI1145 digital UV Index/ IR /visible light sensor and assigned, using Arduino, to an appropriate UV index and IR radiation levels. RESULTS The IR and UV readings were recorded several times and at four different hours through the day. The readings showed its highest value at 10 a.m. and 2 p.m., which are considered the highest sun intensity. The other readings were at 6 a.m. and 5 p.m. and considered the least dangerous hours. CONCLUSION The data collected from the sensor is used to program the alarm. To combine all components, a PCB and a prototype were designed and printed. The UV/IR wristwatch is applicable to alert the user from the continuous and accumulated harmful effects of the radiations and enable them to seek protective measures.

Thus, the aim of this study was to describe the dynamic knee valgus of competitive alpine skiers during drop jump landings (DJ) and single leg squats (SLS) with respect to sex, sportive level and biological maturation. Thirty-seven elite and 104 youth competitive alpine skiers around the growth spurt (U15) were examined for their maximal medial knee displacement (MKD) during DJ and SLS by a marker-based 3D motion analysis evaluating dynamic knee valgus. Additionally, skiers' age, anthropometry and biological maturation were assessed. MKD of youth and elite alpine skiers during DJ was comparable and did not improve with increasing training age. Female U15 skiers (on average further matured) had significantly larger MKD values during DJ than male U15 skiers (less matured) (p  less then  0.01). Moreover, MKD during DJ was directly associated with the athlete's individual biological maturation status. MKD values obtained from DJ significantly differed from those obtained during SLS (p  less then  0.01). The gender-specific difference in MKD values during DJ and their relationship to maturity offset highlight the fundamental changes to the neuromuscular control system during the growth spurt. Thus, biological maturation needs to be considered as a confounding factor for knee valgus screening. Caution is required when evaluating MKD by using high and low dynamic tasks, as corresponding information can differ. This article is protected by copyright.

Twenty compounds that have human V1 /Vdss of 0.053-0.66 were selected from literature. After intravenous administration of the compounds at 0.1 mg/kg to rats, dogs, and monkeys, plasma concentrations were determined, and pharmacokinetic parameters were obtained by one/two-compartmental analyses. The human V1 , Vdss , and Vdβ were predicted from animal Vd using the Øie-Tozer model, and the predictability was compared with that using proportionality and simple allometry. The Øie-Tozer model was the most reliable method for overall prediction of Vd and applicable to accurately predict human V1 , Vdss , and Vdβ (89%, 85%, and 68% of the compounds within 3-fold error, respectively) when data of monkey for V1 and data of three animal species for Vdss and Vdβ were used. Additionally, the predicted human Vd with two-compartment model was applicable to predict pharmacokinetic profiles/parameters in humans after intravenous administration of 18 compounds [except for valproic acid (monophasic elimination profile) and chlorpromazine (deviation Vdss less then V1 )]. The prediction was more accurate than that using the predicted Vdss with one-compartment model (e.g., underestimation of maximum plasma concentrations 2 vs 8 compounds within 3-fold error, respectively). In summary, the Øie-Tozer model was applicable to predict human V1 , Vdss , and Vdβ , and their predicted Vd with two-compartment model can lead to accurate pharmacokinetic prediction of compounds that show biphasic elimination.
