PROBLEM: Context: We tested the hypothesis that harm avoidance, a trait associated with behavioral inhibition, is associated with the rate of change in parkinsonism in older adults.', "At baseline harm avoidance was assessed with a standard self-report instrument in 969 older people without dementia participating in the Rush Memory and Aging Project, a longitudinal community-based cohort study. Parkinsonism was assessed annually with a modified version of the motor section of the Unified Parkinson's Disease Rating Scale (mUPDRS).", 'Average follow-up was 5 years. A linear mixed-effects model controlling for age, sex and education showed that for an average participant (female, 80 years old at baseline, with 14 years of education and a harm avoidance score of 10), the overall severity of parkinsonism increased by about 0.05 unit/ year (Estimate, 0.054, S.E., 0.007, p <0.001) and that the level of harm avoidance was associated with the progression of parkinsonism (Estimate, 0.004, S.E., 0.001, p <0.001). Thus, for an average participant, every 6 point (~1 SD) increase in harm avoidance score at baseline, the rate of progression of parkinsonism increased about 50% compared to an individual with an average harm avoidance score. This amount of change in parkinsonism over the course of the study was associated with about a 5% increased risk of death. The association between harm avoidance and progression of parkinsonism persisted when controlling for cognitive function, depressive symptoms, loneliness, neuroticism, late-life cognitive, social and physical activities and chronic health conditions.
Answer: A higher level of the harm avoidance trait is associated with a more rapid progression of parkinsonism in older adults.

SOLUTION: Is harm avoidance associated with progression of parkinsonism in community-dwelling older adults : a prospective cohort study?

PROBLEM: Context: Facial dog bite injuries pose a significant public health problem.', 'Seventy-five consecutive patients (45 males, 30 females) treated solely by plastic surgery service for facial dog bite injuries at a Level I trauma center in the Denver Metro area between 2006 and 2012 were retrospectively reviewed. The following information were recorded: breed, relationship of patient to dog, location and number of wounds, the duration between injury and surgical repair and dog bite incident, type of repair, and antibiotic prophylaxis. Primary end points measured were wound infection, the need for revision surgery, and patient satisfaction.', 'Ninety-eight wounds in the head and neck region were repaired (46 children; mean age, 6.8 years) and (29 adults; mean age, 47.3 years). Twelve different breeds were identified. There was no significant association between the type of dog breed and the number of bite injuries. The duration between injury and repair ranged from 4 hours to 72 hours (mean [SD], 13.7 [10.9] hours). The majority of bite wounds (76 of 98) involved the cheek, lip, nose, and chin region. Direct repair was the most common surgical approach (60 of 98 wounds) (p < 0.05). There was no statistically significant association between wounds needing reconstruction versus direct repair according to dog breed (p = 0.25). Ten wounds required grafting. Twenty-five wounds were managed by one-stage or two-stage flaps. Only three patients (3.06 %) underwent replantation/revascularization of amputated partial lip (n = 2) and of cheek (n = 1). There was one postoperative infection. Data from five-point Likert scale were available for fifty-two patients. Forty patients were satisfied (5) with the outcome, while five patients were somewhat satisfied (4), and seven were neutral.
Answer: Availability of the plastic surgery service at a Level I trauma center is vital for the optimal treatment of facial dog bite injuries. Direct repair and reconstruction of facial dog bite injuries at the earliest opportunity resulted in good outcomes as evidenced by the satisfaction survey data and low complication rate.

SOLUTION: Do retrospective analysis of facial dog bite injuries at a Level I trauma center in the Denver metro area?

PROBLEM: Context: The mechanisms responsible for the cardiac dysfunction associated with dietary protein restriction (PR) are poorly understood. Thus, this study was designed to evaluate the effects of PR on calcium kinetics, basal and -adrenergic contractility in murine ventricular cardiomyocytes.', 'After breastfeeding male Fisher rats were distributed into a control group (CG, n = 20) and a protein-restricted group (PRG, n = 20), receiving isocaloric diets for 35 days containing 15% and 6% protein, respectively. Biometric and hemodynamic variables were measured. After euthanasia left ventricles (LV) were collected for histopathological evaluation, SERCA2a expression, cardiomyocytes contractility and Ca(2+)sparks analysis.', 'PRG animals showed reduced general growth, increased heart rate and arterial pressure. These animals presented extracellular matrix expansion and disorganization, cardiomyocytes hypotrophy, reduced amplitudes of shortening and maximum velocity of contraction and relaxation at baseline and after -adrenergic stimulation. Reduced SERCA2a expression as well as higher frequency and lower amplitude of Ca(2+)sparks were observed in PRG cardiomyocytes.
Answer: The observations reveal that protein restriction induces marked myocardial morphofunctional damage. The pathological changes of cardiomyocyte mechanics suggest the potential involvement of the -adrenergic system, which is possibly associated with changes in SERCA2a expression and disturbances in Ca(2+) intracellular kinetics.

SOLUTION:
Is basal and -adrenergic cardiomyocytes contractility dysfunction induced by dietary protein restriction associated with downregulation of SERCA2a expression and disturbance of endoplasmic reticulum Ca2+ regulation in rats?
