The Impella devices are percutaneous intravascular ventricular assist devices indicated for use in patients with cardiogenic shock that occurs following acute myocardial infarction (MI) or open heart surgery. These devices must be used with a purge solution that contains heparin per manufacturer recommendation, which will prevent blood from reaching the motor causing pump thrombosis and mechanical failure. We describe the utilization of a dextrose-only purge solution plus systemic argatroban in 2 patients with suspected heparin-induced thrombocytopenia (HIT).

In this study, we investigate the mechanisms of colistin resistance in four isogenic pairs of isolates displaying an increase in colistin MICs. A mutation in was detected in each colistin-resistant isolate, three of which were novel (A28V, I232T, and ΔL9-G12).

Background: How a dentist works, such as the patterns of movements performed daily, is also largely affected by the workstation Dental tasks are often executed in awkward body positions, thereby causing a very high degree of strain on the corresponding muscles. The objective of this study is to detect those dental tasks, during which awkward postures occur most frequently. The isolated analysis of static postures will examine the duration for which these postures are maintained during the corresponding dental, respectively non-dental, activities.

Background: This study aims at identifying orthodontic activities with the highest frequency of unfavorable/awkward and static postures held over a period of more than 4 s based on kinematic analysis. Moreover, a separate analysis of static postures for orthodontic and non-orthodontic activities serves to evaluate the duration for which these particular postures are assumed.
Methods: In total, 21 (13f/8 m) orthodontists (age: 31.

In a previous study, we reported that the Asp20→Asn amino acid substitution in the response regulator AdeR is associated with adeB overexpression and reduced susceptibility to the antimicrobials levofloxacin, tigecycline, and trimethoprim-sulfamethoxazole. To further characterize the effect of the Asp20→Asn substitution on antimicrobial susceptibility, the expression of the efflux genes adeB, adeJ, and adeG, and substrate accumulation, four plasmid constructs [containing adeR(Asp20)S, adeR(Asn20)S, adeR(Asp20)SABC, and adeR(Asn20)SABC] were introduced into the adeRSABC-deficient A.

Efflux-mediated resistance, particularly the resistance-nodulation-division (RND)-type efflux pumps, contributes significantly to decreased susceptibility to multiple antibiotics when overexpressed. Using PCR-based detection, the prevalence of genes encoding the RND efflux pumps AdeB, AdeJ and AdeG was investigated amongst 144 epidemiologically characterized and geographically diverse A.

Our prior studies indicated that postural fainting relates to thoracic hypovolemia. A supranormal increase in initial vascular resistance was sustained by increased peripheral resistance until late during head-up tilt (HUT), whereas splanchnic resistance, cardiac output, and blood pressure (BP) decreased throughout HUT. Our aim in the present study was to investigate the alterations of baroreflex activity that occur in synchrony with the beat-to-beat time-dependent changes in heart rate (HR), BP, and total peripheral resistance (TPR).

Any equipment or technique creating less movement will allow for a more effective and safe stabilization of an injured patient, reducing the likelihood of movement and potential secondary injury.
Objective: To compare the amount of head movement created during the log-roll and motorized spine-board (MSB) stabilization techniques.

Using an analogue sample, we examined whether thought suppression mediated the relationship of negative affective intensity/reactivity and perceived parental criticism with a composite of BPD features including impulsivity, interpersonal sensitivity, and aggression. Results indicated that thought suppression fully mediated the relationship between negative affect intensity/reactivity and BPD features and partially mediated the relationship between BPD features and perceived parental criticism.

By screening a large pool of pilot questions and using methods based in item response theory (IRT), seven items were identified with well-targeted contents that discriminated well across the continuum of eating disorder severity. The resulting measure evidenced a unidimensional factor structure and correlated highly with the original COEDS, standard measures of eating disorders pathology, and a measure of associated symptomatology (e.

To examine these issues, it is first necessary to identify a brief screening measure that can be used to assess factors underlying BPD. Considering this need, the current investigation examined the utility of a BPD-related composite consisting of the Inventory of Interpersonal Problems-Interpersonal Sensitivity (IIP-IS) and Aggression (IIP-Ag) subscales of the IIP in a sample of college students ( [Formula: see text] ) and a sample of individuals seeking residential drug use treatment ( [Formula: see text] ).
