Question: 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.

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


Question: Context: Diabetic cardiomyopathy (DCM) is associated with suppressed autophagy and augmented apoptosis in the heart although the interplay between the two remains elusive. The ability of mammalian sterile 20-like kinase 1 to regulate both autophagy and apoptosis prompted us to investigate it as a possible candidate in the progression of DCM.', 'Wild-type, Mst1 (also known as Stk4) transgenic and Mst1-knockout mice were challenged with streptozotocin to induce experimental diabetes. In addition, cultured neonatal mouse cardiomyocytes were subjected to simulated diabetes to probe mechanisms.', 'Mst1 knockout alleviated while Mst1 overexpression aggravated cardiac dysfunction in diabetes. Diabetic Mst1 transgenic mice exhibited decreased LC3 expression and enhanced protein aggregation. In contrast, typical autophagosomes were observed in diabetic Mst1-knockout mice with increased LC3 expression and reduced protein aggregation. Mst1 downregulation promoted autophagic flux as demonstrated by increased LC3-II and decreased p62 expression in the presence of bafilomycin A1. Furthermore, Mst1 overexpression increased, while Mst1 knockout decreased, cardiomyocyte apoptosis both in vivo and in vitro. Co-immunoprecipitation assays showed that Mst1 overexpression promoted Beclin1 binding to B cell lymphoma 2 (Bcl-2) and induced dissociation of Bcl-2 from Bax in diabetic mice. Conversely, Mst1 knockout disrupted the Beclin1-Bcl-2 complex and enhanced the interaction between Bcl-2 and Bax.
Answer: Mst1 knockout restores autophagy and protects against apoptosis in cardiomyocytes, en route to the rescue against DCM.

Answer: Does mST1 coordinately regulate autophagy and apoptosis in diabetic cardiomyopathy in mice?


Question: Context: Subdural arrays of grid and strip electrodes are frequently used in epilepsy patients to localize the seizure focus and determine the location of critical brain functions via stimulation mapping. Postoperatively, the majority of patients with implanted subdural electrodes develop subacute extra-axial collections (EACs). Although conservative management is appropriate in most of these cases, occasionally patients manifest neurological symptoms that may necessitate reoperation for collection evacuation. Currently, there is little information available regarding the range of EAC size and the potential correlation between EAC size and symptom development. To facilitate treatment decision-making in postoperative subdural electrode patients, we reviewed and compared the computed tomographic (CT) features of postelectrode placement EACs in asymptomatic and symptomatic patients.', 'We retrospectively reviewed the medical records and CT scans of 22 consecutive patients who underwent craniotomy for placement of subdural grid and strip electrodes at Columbia University Medical Center. Medical records were reviewed for neurological complications from the time of grid placement until its removal. Each EAC was measured on CT for volume (% of total cranial volume), maximal thickness, and midline shift. One patient was excluded secondary to the development of an intracerebral hemorrhage.', 'Thirteen of 21 patients remained asymptomatic or minimally symptomatic during their hospitalization, with only mild to moderate, intermittent, postoperative headaches. The remaining eight developed symptoms such as persistent and severe headache, transient motor deficit, or speech impairment. Two of these patients underwent reoperation for hematoma evacuation. EACs in asymptomatic patients had a mean volume, maximal thickness, and midline shift of 5.7%, 1.25 cm, and 0.33 cm, respectively. EACs in symptomatic patients had a mean volume, maximal thickness, and midline shift of 7.7%, 1.46 cm, and 0.5 cm, respectively. Differences between maximal thickness and midline shift did not approach statistical significance. Despite this, the difference between the mean volume of symptomatic and asymptomatic EACs was statistically significant (P = 0.04).
Answer: The conventional methods of midline shift and maximal thickness for assessing EAC size did not adequately differentiate symptomatic and asymptomatic subdural electrode patients with EACs. Although total volume calculation using digital planimetric analysis demonstrated a statistically significant difference, we found no clear threshold volume that correlated with clinical course. Therefore, the appearance of EACs on CT scans is of limited use in predicting the development of symptoms and possible postoperative complications after subdural grid placement. Clinical judgment must guide management and determine the potential need for reoperation.

Answer:
Do radiographic characteristics fail to predict clinical course after subdural electrode placement?
