Feasibility of Problem Adaption Therapy in a Diverse, Frail Older Adult Population (PATH-MHS)

The purpose of the Problem Adaptation Therapy - Montefiore Health System (PATH-MHS) pilot program was to demonstrate the feasibility and effectiveness of PATH across a culturally, educationally, and functionally diverse cohort of older adults.

METHODS

Clinicians referred 145 participants with depression and cognitive impairment to PATH-MHS. We completed analyses of the change in depression, disability and the association between baseline characteristics and remission of depression.

RESULTS

Most participants were Hispanic or Non-Hispanic Black and 54.7% (76) were primary Spanish speakers. Overall, there were significant decreases in the mean PHQ-9 and WHODAS 2.0 scores. In logistic regression models, neither age, education, gender, race/ethnicity, language nor long-term care status was significantly associated with remission of depression.

CONCLUSIONS

This study demonstrates that we were able to engage a diverse, cognitively impaired, and frail cohort of older adults in PATH-MHS with significant reductions in depression and disability.

Developing a Structural Intervention for Outpatient Mental Health Care: Mapping Vulnerability and Privilege

The Mapping Vulnerability and Privilege (MVP) exercise is a clinical intervention based on a structural competency framework that emphasizes societal structures-social determinants of health and of biology, behavior, and culture-and their impact on health outcomes. The exercise comprises the MVP Tool, Visual Guide, and Processing Guide. It was created with the goals of helping clinicians to develop structural humility and introducing a structural lens for viewing the therapeutic milieu and the structural barriers that affect both intrapsychic experiences and interactions with the health care system, while encouraging patients and clinicians to take action to address the systemic and structural issues that affect patients' well-being. This article provides an overview of the development of the MVP exercise as an educational and clinical intervention.

RNA-seq analysis of murine peyer's patches at 6 and 18 h post infection with Fasciola hepatica metacecariae

Fasciola hepatica is a zoonotic parasite that not only economically burdens the agribusiness sector, but also infects up to 1 million people worldwide, with no commercial vaccine yet available. An ideal vaccine would induce protection in the gut, curtailing the extensive tissue damage associated with parasite's migration from the gut to the bile ducts. The design of such a vaccine requires greater knowledge of gut mucosal responses during the early stage of infection. We examined total mRNA expression of the peyer's patches at 6 and 18 h post F. hepatica infection using RNA sequencing. Differential expression analysis revealed 1341 genes upregulated and 61 genes downregulated at 6 h post infection, while 1562 genes were upregulated and 10 genes downregulated after 18 h. Gene-set enrichment analysis demonstrated that immune specific biological processes were amongst the most downregulated. The Toll-like receptor pathway in particular was significantly affected, the suppression of which is a well-documented immune evasive strategy employed by F. hepatica. In general, the genes identified were associated with suppression of inflammatory responses, helminth induced immune responses and tissue repair/homeostasis. This study provides a rich catalogue of the genes expressed in the early stages of F. hepatica infection, adding to the understanding of early host-parasite interactions and assisting in the design of future studies that look to advance the development of a novel F. hepatica vaccine.

Variable Cold-Induced Brown Adipose Tissue Response to Thyroid Hormone Status

BACKGROUND

In addition to its role in adaptive thermogenesis, brown adipose tissue (BAT) may protect from weight gain, insulin resistance/diabetes, and metabolic syndrome. Prior studies have shown contradictory results regarding the influence of thyroid hormone (TH) levels on BAT volume and activity. The aim of this pilot study was to gain further insights regarding the effect of TH treatment on BAT function in adult humans by evaluating the BAT mass and activity prospectively in six patients, first in the hypothyroid and then in the thyrotoxic phase.

METHODS

The study subjects underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) scanning after cold exposure to measure BAT mass and activity while undergoing treatment for differentiated thyroid cancer, first while hypothyroid following TH withdrawal at the time of the radioactive iodine treatment and then three to six months after starting TH suppressive treatment when they were iatrogenically thyrotoxic. Thermogenic and metabolic parameters were measured in both phases.

RESULTS

All study subjects had detectable BAT under cold stimulation in both the hypothyroid and thyrotoxic state. The majority but not all (4/6) subjects showed an increase in detectable BAT volume and activity under cold stimulation between the hypothyroid and thyrotoxic phase (total BAT volume: 72.0 ± 21.0 vs. 87.7 ± 16.5 mL, p = 0.25; total BAT activity 158.1 ± 72.8 vs. 189.0 ± 55.5 SUV*g/mL, p = 0.34). Importantly, circulating triiodothyronine was a stronger predictor of energy expenditure changes compared with cold-induced BAT activity.

CONCLUSIONS

Iatrogenic hypothyroidism lasting two to four weeks does not prevent cold-induced BAT activation, while the use of TH to induce thyrotoxicosis does not consistently increase cold-induced BAT activity. It remains to be determined which physiological factors besides TH play a role in regulating BAT function.

The time taken to complete quality of life questionnaires in an advanced cancer trial

8592

Background: Respondent burden is important when designing trials in advanced cancer. We determined the time taken to complete a set of quality of life questionnaires (TTTCQ) in a randomized trial of sertraline in advanced cancer. Methods: Participants recorded the times they started and finished an 11 page questionnaire of 187 items including the Centre for Epidemiologic Studies Depression Scale, Hospital Anxiety and Depression Scale, Functional Assessment of Cancer Therapy General and Fatigue scales, and 4 other validated instruments. Determinants of the TTTCQ were sought amongst the self-ratings of anxiety, depression, fatigue, trouble concentrating, other aspects of quality of life, and other characteristics including age, Karnofsky Performance Status (KPS) and treatment. Distributions are summarised by their median, interquartile range (25th to 75th percentiles, IQR) and interdecile range (10th to 90th percentiles, IDR). Associations were assessed with Spearman’s rank correlation coefficient (r), and differences with the Mann-Whitney test. All p-values are two-sided. Results: The TTTCQ was available for 128 of 150 subjects (85%). Median age was 66 (IQR 59 to 73), median KPS was 80 (IQR 70 to 90), and 63% were male. The median TTTCQ was 30 mins (IQR 23 to 40, IDR 15 to 50), equating to a median of 10 secs per item (IQR 7 to 13, IDR 5 to 16). The TTTCQ was modestly correlated with age and KPS (r = 0.19, p = 0.04 for both). Age and KPS were not correlated (r = 0.03, p = 0.8). Subjects aged 60 or older had a median TTTCQ 10 mins longer than those 59 or younger (35 v 25 mins, p = 0.002). Subjects with a KPS of 100, 90, 80, and 70 or less had a median TTTCQ of 20, 25, 31, and 35 mins respectively. TTTCQ was modestly correlated with self-ratings of: problems coping with treatment, dry mouth, feeling dizzy or lightheaded (r = 0.22 to 0.25, p = 0.01). Correlations were weak or non-existent with all measures of depression, anxiety, trouble concentrating, emotional well-being, and overall well-being (r = 0.10 to 0.18, p = 0.04 to 0.25). TTTCQ was unaffected by gender, opioids, steroids and number of previous cytotoxic regimens. Conclusions: Respondent burden was less of a problem than anticipated and little affected by treatments or self-rated psychological problems.

An isolated epizootic of hemorrhagic-like fever in cats caused by a novel and highly virulent strain of feline calicivirus

An isolated epizootic of a highly fatal feline calicivirus (FCV) infection, manifested in its severest form by a systemic hemorrhagic-like fever, occurred over a 1-month period among six cats owned by two different employees and a client of a private veterinary practice. The infection may have started with an unowned shelter kitten that was hospitalized during this same period for a severe atypical upper respiratory infection. The causative agent was isolated from blood and nasal swabs from two cats; the electron microscopic appearance was typical for FCV and capsid gene sequencing showed it to be genetically similar to other less pathogenic field strains. An identical disease syndrome was recreated in laboratory cats through oral inoculation with tissue culture grown virus. During the course of transmission studies in experimental cats, the agent was inadvertently spread by caretakers to an adjoining room containing a group of four normal adult cats. One of the four older cats was found dead and a second was moribund within 48-72h in spite of symptomatic treatment; lesions in these animals were similar to those of the field cats but with the added feature of severe pancreatitis. The mortality in field cats, deliberately infected laboratory cats, and inadvertently infected laboratory cats ranged from 33-50%. This new isolate of calicivirus, named FCV-Ari, was neutralized at negligible to low titer by antiserum against the universal FCV-F9 vaccine strain. Cats orally immunized with FCV-F9, and then challenge-exposed shortly thereafter with FCV-Ari, developed a milder self-limiting form of disease, indicating partial protection. However, all of the field cats, including the three that died, had been previously immunized with parenteral FCV-F9 vaccine. FCV-Ari caused a disease that was reminiscent of Rabbit Hemorrhagic Disease, a highly fatal calicivirus infection of older rabbits.

Emerging and reemerging infectious diseases: a multidisciplinary perspective

Predictions that infectious diseases would be eliminated as a major threat to human health have been shattered by emerging and reemerging infections, among them acquired immunodeficiency syndrome (AIDS), hemorrhagic fevers, marked increases in infections caused by antimicrobial-resistant bacteria, and the resurgence of tuberculosis and malaria. Understanding the dynamics of emerging and reemerging infections is critical to efforts to reduce the morbidity and mortality of such infections, to establish policy related to preparedness for infectious threats, and for decisions on where to use limited resources in the fight against infections. In order to offer a multidisciplinary perspective, 23 infectious disease specialists, epidemiologists, geneticists, microbiologists, and population biologists participated in an open forum at Emory University on emerging and reemerging infectious diseases. As summarized below, the group addressed questions about the definition, the identification, the factors responsible for, and multidisciplinary approaches to emerging and reemerging infections.

The role of temperament in children with insulin-dependent diabetes mellitus

Investigated the role of child temperament and diabetes-related environmental demands on the adjustment of children with insulin-dependent diabetes mellitus (IDDM) and investigated the role of these same variables on diabetes control. Parents of 117 children completed questionnaires assessing their child's temperament, diabetes-specific environmental demands, and psychosocial adjustment. Glycohemoglobin (HbA1C) and demographics were obtained. Analyses evaluated the incremental variance accounted for by temperament and environmental demands after controlling for the effects of the demographic variables. Results suggest that lower activity and greater flexibility were related to fewer behavior problems. Greater persistence and less distractibility were related to fewer social competence problems. Greater flexibility and negative moods were related to better metabolic control. Greater child responsibility for the diabetes regimen was related to more behavior problems.
