Assessment of Didactic Transesophageal Echocardiography Education During Anesthesia Residency.

Background: Transesophageal echocardiography can be a useful monitor during noncardiac surgery, in patients with comorbidities and/or undergoing procedures associated with substantial hemodynamic changes. The goal of this study was to investigate if transesophageal-echocardiography-related knowledge could be acquired during anesthesia residency.

Methods: After institutional review board approval, a prospective observational study was performed in two anesthesiology residency programs.

Sex specific cognitive differences in Parkinson disease.

Parkinson disease (PD) is a progressive neurodegenerative disorder that is 1.5 times more common in males than in females. While motor progression tends to be more aggressive in males, little is known about sex difference in cognitive progression.

MRI-guided laser interstitial thermal thalamotomy for medically intractable tremor disorders.

Introduction: Medically intractable tremors are a common, difficult clinical situation. Deep brain stimulation decreases Parkinson's disease resting tremor and essential tremor, but not all patients are candidates from a diagnostic, medical, or social standpoint, prompting the need for alternative surgical strategies.

Methods: We describe 13 patients with medically intractable tremor treated with laser interstitial thermal thalamotomy performed under general anesthesia using live MRI-guidance and the Clearpoint stereotactic system.

The Relationship Between Maladaptive Personality and Social Role Impairment in Depressed Older Adults in Primary Care.

: Personality pathology is associated with impaired social functioning in adults, though further evidence is needed to examine the individual contributions of personality traits and processes to social functioning in depressed older adults. This study is a secondary analysis examining the relationship between maladaptive personality traits and processes and social role impairment in depressed older adults in primary care. : Participants (N = 56) were 77% female and ranged in age between 55-89 (= 66.

Altered Cortico-Limbic Network Connectivity in Parkinsonian Depression: The Effect of Antidepressants.

Background: Depression is a common comorbidity of Parkinson's disease (PD); however, the impact of antidepressant status on cortical function in parkinsonian depression is not fully understood. While studies of resting state functional MRI in major depression have shown that antidepressant treatment affects cortical connectivity, data on connectivity and antidepressant status in PD is sparse.

Objective: We tested the hypothesis that cortico-limbic network (CLN) resting state connectivity is abnormal in antidepressant-treated parkinsonian depression.

Discovery of a CLN7 model of Batten disease in non-human primates.

We have identified a natural Japanese macaque model of the childhood neurodegenerative disorder neuronal ceroid lipofuscinosis, commonly known as Batten Disease, caused by a homozygous frameshift mutation in the CLN7 gene (CLN7). Affected macaques display progressive neurological deficits including visual impairment, tremor, incoordination, ataxia and impaired balance. Imaging, functional and pathological studies revealed that CLN7 macaques have reduced retinal thickness and retinal function early in disease, followed by profound cerebral and cerebellar atrophy that progresses over a five to six-year disease course.

Psychotherapy Termination Practices with Older Adults: Impact of Patient and Therapist Characteristics.

Objectives: The aims of this study were to survey clinicians' opinions regarding psychotherapy practices in mutual termination with a specified population (depressed older adult outpatients) and to examine the patient and therapist characteristics that may influence such practices.

Methods: We surveyed psychologists' (N = 96) psychotherapy termination practices, using a hypothetical depressed older adult as a referent, to assess consensus on the appropriateness of various guidelines to termination and to examine whether these differ as a function of patient and therapist characteristics.

Results: Several practices were generally agreed to be "extremely appropriate" when terminating psychotherapy with older adults, including collaborating to determine the end date of treatment and discussing patient growth.

Prevention of tuberculosis in rhesus macaques by a cytomegalovirus-based vaccine.

Despite widespread use of the bacille Calmette-Guérin (BCG) vaccine, tuberculosis (TB) remains a leading cause of global mortality from a single infectious agent (Mycobacterium tuberculosis or Mtb). Here, over two independent Mtb challenge studies, we demonstrate that subcutaneous vaccination of rhesus macaques (RMs) with rhesus cytomegalovirus vectors encoding Mtb antigen inserts (hereafter referred to as RhCMV/TB)-which elicit and maintain highly effector-differentiated, circulating and tissue-resident Mtb-specific CD4 and CD8 memory T cell responses-can reduce the overall (pulmonary and extrapulmonary) extent of Mtb infection and disease by 68%, as compared to that in unvaccinated controls, after intrabronchial challenge with the Erdman strain of Mtb at ∼1 year after the first vaccination. Fourteen of 34 RhCMV/TB-vaccinated RMs (41%) across both studies showed no TB disease by computed tomography scans or at necropsy after challenge (as compared to 0 of 17 unvaccinated controls), and ten of these RMs were Mtb-culture-negative for all tissues, an exceptional long-term vaccine effect in the RM challenge model with the Erdman strain of Mtb.

Longer Duration of MAO-B Inhibitor Exposure is Associated with Less Clinical Decline in Parkinson's Disease: An Analysis of NET-PD LS1.

Background: Monoamine oxidase type B (MAO-B) inhibitors exhibit neuroprotective effects in preclinical models of PD but clinical trials have failed to convincingly demonstrate disease modifying benefits in PD patients.

Objective: To perform a secondary analysis of NET-PD LS1 to determine if longer duration of MAO-B inhibitor exposure was associated with less clinical decline.

Methods: The primary outcome measure was the Global Outcome (GO), comprised of 5 measures: change from baseline in the Schwab and England (ADL) scale, the 39-item Parkinson's Disease Questionnaire (PDQ-39), the UPDRS Ambulatory Capacity Scale, the Symbol Digit Modalities Test, and the most recent Modified Rankin Scale.

Cognitive and Psychiatric Disturbances in Parkinsonian Syndromes.

Parkinsonian syndromes share clinical signs including akinesia/bradykinesia and rigidity, which are consequences of pathology involving dopaminergic substantia nigra neurons. Yet cognitive and psychiatric disturbances are common, even early in the course of disease. Executive dysfunction is often measurable in newly diagnosed Parkinson's disease.

Positive attitude toward life, emotional expression, self-rated health, and depressive symptoms among centenarians and near-centenarians.

Objectives: Favorable attitudes, emotions, personality characteristics, and self-rated health have been associated with successful aging in late life. However, less is known regarding these constructs and their relationships to mental health outcomes in the oldest old persons. This study examined cross-sectional relationships of these psychological factors to depressive symptoms in centenarians and near-centenarians.

Parkinson's disease severity and use of dopaminergic medications.

Background: The effects of dopaminergic therapy in parkinson's disease (PD) can vary depending on the class of medication selected.

Objective: The aim of this post hoc study was to determine if the class of dopaminergic therapy correlated with disease severity in persons with early, treated PD.

Methods: A non-parametric global statistical test (GST) was used to assess the status of participants treated with dopamine agonist (DA) monotherapy, levodopa (LD) monotherapy or combined LD and DA therapy on multiple PD outcomes encompassing motor, cognitive, psychiatric and autonomic function, as well as disability and quality of life.

Food deprivation and nicotine correct akinesia and freezing in Na(+) -leak current channel (NALCN)-deficient strains of Caenorhabditis elegans.

Mutations in various genes adversely affect locomotion in model organisms, and thus provide valuable clues about the complex processes that control movement. In Caenorhabditis elegans, loss-of-function mutations in the Na(+) leak current channel (NALCN) and associated proteins (UNC-79 and UNC-80) cause akinesia and fainting (abrupt freezing of movement during escape from touch). It is not known how defects in the NALCN induce these phenotypes or if they are chronic and irreversible.

A randomized clinical trial of high-dosage coenzyme Q10 in early Parkinson disease: no evidence of benefit.

Importance: Coenzyme Q10 (CoQ10), an antioxidant that supports mitochondrial function, has been shown in preclinical Parkinson disease (PD) models to reduce the loss of dopamine neurons, and was safe and well tolerated in early-phase human studies. A previous phase II study suggested possible clinical benefit.

Objective: To examine whether CoQ10 could slow disease progression in early PD.

Personality, self-rated health, and cognition in centenarians: do personality and self-rated health relate to cognitive function in advanced age?

Personality and self-rated health have been linked previously to cognitive outcome in late life. However, these associations have not been shown among the oldest old. This study examined relationships between personality, self-rated health, and cognitive function in a selected sample of Ashkenazi Jewish centenarians (n=68, 59% female) aged 95 to 106 who lived independently in the community.

Learning From The Past and Planning For The Future: The Challenges Of And Solutions For Integrating Aging Into Doctoral Psychology Training.

The long forecast "elder boom" has begun. Beginning in 2011, ten thousand members of the "baby boom" generation began turning 65 each day. This demographic shift in our society mandates that pre-doctoral programs in clinical psychology incorporate aging as an integral component of their core and elective training.

Positive attitude towards life and emotional expression as personality phenotypes for centenarians.

Centenarians have been reported to share particular personality traits including low neuroticism and high extraversion and conscientiousness. Since these traits have moderate to high heritability and are associated with various health outcomes, personality appears linked to bio-genetic mechanisms which may contribute to exceptional longevity. Therefore, the present study sought to detect genetically-based personality phenotypes in a genetically homogeneous sample of centenarians through developing and examining psychometric properties of a brief measure of the personality of centenarians, the Personality Outlook Profile Scale (POPS).

Health and social adjustment of homeless older adults with a mental illness.

Objective: To better inform treatment strategies, this study compared mental health, substance use, physical health, and social support among young, middle-aged, and older homeless adults before and after participation in intensive case management services.

Methods: Data were obtained from the Access to Community Care and Effective Services and Supports (ACCESS) public database. Young (age 18 to 34; N=2,469), middle-aged (age 35 to 54; N=4,358), and older (age 55 or older; N=408) homeless adults with a mental illness were compared on the basis of demographic characteristics and measures of substance use, mental and general medical health, and social support at baseline by using Kruskal-Wallis and chi square tests and at three-month and 12-month follow-ups by using mixed-model analysis.

Medical and psychology students' knowledge and attitudes regarding aging and sexuality.

The current study surveys medical and doctoral psychology students (N = 100) from an urban northeastern university regarding knowledge and attitudes toward elderly sexuality and aging using the Facts on Aging Quiz, the Aging Sexuality Knowledge and Attitudes Scale, and measures of interest in gerontology, academic/clinical exposure to aging and sexuality, and contact with elders. The current study found that psychology students demonstrated greater aging knowledge than medical students; however, both groups showed gaps in knowledge about sexuality. Married students had greater academic/clinical exposure and greater knowledge about aging but less permissive attitudes toward elderly sexuality.

Carcinomatous meningitis secondary to transitional cell bladder cancer.

We report a patient with carcinomatous meningitis secondary to known transitional cell carcinoma of the bladder. The patient presented with multiple focal neurological signs and symptoms. Diagnosis was suggested by magnetic resonance imaging and confirmed by analysis of the cerebrospinal fluid.

Transcriptome analysis of a tau overexpression model in rats implicates an early pro-inflammatory response.

Neurofibrillary tangles comprised of the microtubule-associated protein tau are pathological features of Alzheimer's disease and several other neurodegenerative diseases, such as progressive supranuclear palsy. We previously overexpressed tau in the substantia nigra of rats and mimicked some of the neurodegenerative sequelae that occur in humans such as tangle formation, loss of dopamine neurons, and microgliosis. To study molecular changes involved in the tau-induced disease state, we used DNA microarrays at an early stage of the disease process.

Istradefylline as monotherapy for Parkinson disease: results of the 6002-US-051 trial.

Objective: 6002-US-051 was a 12-week, double-blind study evaluating the safety and efficacy of istradefylline, a selective A(2A) adenosine receptor antagonist, as monotherapy in patients with Parkinson's disease (PD).

Methods: Patients with Hoehn-Yahr stages 1-2.5 who had not received dopaminergic drugs in the past 30 days or levodopa for >30 days at anytime were randomized to 40 mg/day istradefylline or placebo.
