Expressive Interviewing Agents to Support Health-Related Behavior Change: Randomized Controlled Study of COVID-19 Behaviors.

Background: Expressive writing and motivational interviewing are well-known approaches to help patients cope with stressful life events. Although these methods are often applied by human counselors, it is less well understood if an automated artificial intelligence approach can benefit patients. Providing an automated method would help expose a wider range of people to the possible benefits of motivational interviewing, with lower cost and more adaptability to sudden events like the COVID-19 pandemic.

A habitat stronghold on the precipice: A call-to-action for supporting lemur conservation in northeast Madagascar.

The northeast of Madagascar is as diverse as it is threatened. The area bordering the Analanjirofo and SAVA regions contains six protected areas and at least 22 lemur species. Many applied research and conservation programs have been established in the region with the aim of ensuring both wildlife and people thrive in the long term.

Back to basics: Gaps in baseline data call for revisiting an environmental education program in the SAVA region, Madagascar.

Environmental education programs are critically important for raising awareness about global and local environmental concerns, by providing the knowledge, tools, and means for young and old generations to cope with current challenges. Of the greatest importance is the implementation of environmental education programs in biodiversity hotspots where environmental crises are high and resources to fund mitigation programs are low. Madagascar is one such priority hotspot, featuring intensive wildlife-human conflicts due to shrinking natural environments.

Common Use of Electroconvulsive Therapy for Chinese Adolescent Psychiatric Patients.

Purpose: Little is known about the use of electroconvulsive therapy (ECT) for adolescent psychiatric patients in China. This study examined the frequency of ECT and the demographic and clinical correlates of adolescent psychiatric patients hospitalized in a tertiary psychiatric hospital in China.

Methods: This was a retrospective chart review of 954 inpatients aged between 13 and 17 years treated over a period of 8 years (2007-2013).

Minimum Effective Doses of Succinylcholine and Rocuronium During Electroconvulsive Therapy: A Prospective, Randomized, Crossover Trial.

Background: Neuromuscular blockade is required to control excessive muscle contractions during electroconvulsive therapy (ECT). In a crossover, assessor-blinded, prospective randomized study, we studied the minimum effective dose (MED) of succinylcholine and rocuronium for ECT. The MED was the lowest dose to provide a predefined qualitative measure of acceptable control of muscle strength during induced convulsions.

Rapid improvement of depression and psychotic symptoms in Huntington's disease: a retrospective chart review of seven patients treated with electroconvulsive therapy.

Many patients with Huntington's disease (HD) develop psychiatric symptoms such as depression and psychosis. For severe symptoms, electroconvulsive therapy (ECT) can be a valuable treatment. In this case series, we identified seven patients with HD who received ECT at Massachusetts General Hospital in the past 20 years.

A double-blind, placebo-controlled study of the impact of galantamine on anterograde memory impairment during electroconvulsive therapy.

Background: Electroconvulsive therapy (ECT) continues to be an effective treatment option for patients who fail to respond to pharmacological interventions, are unable to tolerate medications, and show a suboptimal response to behavioral and psychotherapeutic treatments. However, risks for cognitive impairment may contribute to some patients' refusal of ECT.

Methods: The present study examined galantamine as a pharmacological intervention to reduce cognitive adverse effects from ECT.

Very-high-strength (60-GPa) carbon nanotube fiber design based on molecular dynamics simulations.

The mechanical properties of carbon nanotubes such as low density, high stiffness, and exceptional strength make them ideal candidates for reinforcement material in a wide range of high-performance composites. Molecular dynamics simulations are used to predict the tensile response of fibers composed of aligned carbon nanotubes with intermolecular bonds of interstitial carbon atoms. The effects of bond density and carbon nanotube length distribution on fiber strength and stiffness are investigated.

Successful management of a morbidly obese patient for electroconvulsive therapy with elective tracheostomy.

Electroconvulsive therapy (ECT) is a treatment for affective catatonia and requires multiple general anesthetics. Morbid obesity is an increasingly prevalent condition that may complicate the standard anesthetic management of a patient undergoing ECT. We report the successful airway management of a morbidly obese ECT patient via elective tracheostomy.

Long-term risk of repeat occupational injury or illness incidents among veterans health administration nursing employees.

This retrospective population-based study assessed the long-term risk of repeat reported occupational injury or illness incidents among Veterans Health Administration (VHA) nursing employees. Using fiscal year (FY) 2002 as the start date for the longitudinal surveillance of incidents, descriptive analyses included all VHA nursing employees (N = 25,697) who reported an initial (index) incident that occurred between FY 2002 and FY 2005. Adjusted for total administrative loss rates (e.

Enzyme-mediated assimilation of DNA-functionalized single-walled carbon nanotubes.

When pyrimidine-functionalized carbon nanotubes were incubated with single-stranded DNA ligase, formations of macroscopic aggregates were observed. Wet-cell transmission electron microscopy imaging revealed that the nanotubes were radially bound to form a 3D latticelike structure. These structures were not observed in control reactions lacking ligase or adenosine triphosphate.

Depression and costs of health care.

Background: In spite of its global importance, the interaction between depression and chronic comorbid diseases remains incompletely understood with regard to prevalence, severity of disease, and potential causative factors mediating this interaction.

Objective: The authors sought to compare overall medical costs in nondepressed and depressed individuals.

Method: Insurance claims for 618,780 patients were examined for total annual non-mental health cost of care in 11 chronic diseases.

Nutrient composition of plants consumed by black and white ruffed lemurs, Varecia variegata, in the Betampona Natural Reserve, Madagascar.

The purpose of this study was to quantify the concentrations of crude protein, fat, ash, neutral detergent fiber, acid detergent fiber, lignin, nonstructural carbohydrates, and gross energy in plant foods consumed by wild black and white ruffed lemurs (Varecia variegata). Calcium, phosphorous, magnesium, potassium, sodium, iron, zinc, copper, manganese, molybdenum, and selenium concentrations were also determined. A total of 122 samples from 33 plant families and more than 60 species were collected and analyzed for their nutritional content.

Encephalitis and catatonia treated with ECT.

Objective: To describe 2 cases of encephalitis with neuropsychiatric symptoms including catatonia, compounded by neuroleptic use for delirious agitation culminating in malignant catatonia responsive to electroconvulsive therapy (ECT).

Background: Neuropsychiatric symptoms including catatonia can be manifestations of limbic encephalitis and encephalitides of unidentified etiology, including encephalitis lethargica. Catatonic features are often difficult to appraise in this context.

Tight-binding molecular dynamics study of the role of defects on carbon nanotube moduli and failure.

We performed tight-binding molecular dynamics on single-walled carbon nanotubes with and without a variety of defects to study their effect on the nanotube modulus and failure through bond rupture. For a pristine (5,5) nanotube, Young's modulus was calculated to be approximately 1.1 TPa, and brittle rupture occurred at a strain of 17% under quasistatic loading.

The impact of galantamine on cognition and mood during electroconvulsive therapy: a pilot study.

Objectives: The purpose of this study was to: (1) assess the effectiveness of galantamine in the prevention of cognitive impairments during ECT treatment and (2) to explore the safety and tolerability of galantamine during ECT treatment.

Methods: Nine consecutive ECT patients were given galantamine 4 mg bid throughout the course of their ECT treatments followed by a second cohort of eight consecutive ECT patients who did not receive galantamine. Objective measures of cognitive functioning and depression severity were performed pre-ECT and post-ECT.

Intraperitoneal cefazolin and ceftazidime effects on human peritoneal mesothelial cell release of cancer antigen-125.

Background: Intraperitoneal (IP) cefazolin and ceftazidime are recommended as empiric treatment for peritoneal dialysis (PD)-associated peritonitis. Human peritoneal mesothelial cells (HPMCs) may be affected by high IP cefazolin and ceftazidime concentrations. Peritoneal dialysate cancer antigen-125 (CA-125) appearance rate can be used to measure HPMC damage.

Atropine in Electroconvulsive Therapy.

Nineteen patients with major depression were alternately given intravenous atropine or saline immediately prior to anesthesia for electroconvulsive therapy (ECT). Atropine increased the heart rate, reduced the number of dropped beats, and reduced the number of premature atrial beats. These features may be advantageous in patients with cardiac hypodynamic states presenting for ECT, that is, with bradycardia, bradyarrhythmia, or hypotension.
