This capsule review is a discussion of myofascial pain syndrome in small animals. The history of myofascial pain syndrome is discussed as well as facts and theories behind the aetiology and treatment of this syndrome. Diagnostic techniques are both discussed and illustrated.

The hydrogen-plasma-treated and untreated ZnO films exhibited ohmic behavior with room-temperature in-plane conductivity in a vacuum. When the untreated ZnO film was exposed to a dry oxygen environment, the conductivity rapidly decreased, and an oscillating current was observed.

- - The study evaluated the quality-adjusted life years (QALYs) in older heart failure patients (ages 60-80) who received either heart transplants (with or without pre-transplant mechanical support) or long-term mechanical circulatory support.
- - Data from 393 patients showed that those who underwent heart transplantation without pre-surgery support had significantly higher QALYs at 24 months compared to those who had pre-surgery support or long-term mechanical support.
- - Findings suggest that QALY assessments can guide healthcare policy and clinical decisions regarding the most beneficial treatment options for elderly patients with heart failure.
Background: Information about health-related quality of life (HRQOL) among caregivers of older patients with heart failure who receive heart transplantation (HT) and mechanical circulatory support (MCS) is sparse. We describe differences and factors associated with change in HRQOL before and early post-surgery among caregivers of older heart failure patients who underwent 3 surgical therapies: HT with pretransplant MCS (HT MCS), HT without pretransplant MCS (HT non-MCS), and long-term MCS.
Methods: Caregivers of older patients (60-80 years) from 13 US sites completed the EQ-5D-3 L visual analog scale (0 [worst]-100 [best] imaginable health state) and dimensions before and 3 and 6 months post-surgery.
Background: Caregiving for heart failure (HF) patients is burdensome. We examined differences in caregiver burden for 3 groups of older advanced HF patients: (1) supported with mechanical circulatory support (MCS) before heart transplantation (HT MCS), (2) awaiting transplant without MCS (HT non-MCS), and (3) prior to long-term MCS and factors associated with burden.
Method: From October 1, 2015 to December 31, 2018, we enrolled 276 caregivers for HF patients from 13 U.
