Randomized Controlled Trial
Effect of aerobic exercise on quality of life in population with diabetic peripheral neuropathy in type 2 diabetes: a single blind, randomized controlled trial.
To evaluate the effect of 8-week moderate intensity aerobic (heart-rate reserve 40-60%) exercise on neuropathy quality of life in type 2 diabetes. ⋯ Moderate intensity aerobic exercise is cornerstone in improving the quality of life of individuals with peripheral neuropathy in type 2 diabetes.

There is a growing population of older people living alone within the context of dramatic population ageing and changing living arrangements. However, little is known about the quality of life (QoL) of older people living alone in Mainland China. This study aimed to investigate QoL and its related factors among Chinese older people who live alone. ⋯ This study identified nine factors influencing the QoL of older people living alone in Mainland China. Interventions to increase satisfaction with dwelling conditions, improve economic level, social support and functional ability, decrease loneliness and depression and improve health services satisfaction appear to be important for enhancing their QoL.

Study aim was to translate the PROMIS(®) pain interference (PI) item bank (41 items) into German, test its psychometric properties in patients with chronic low back pain and develop static subforms. ⋯ The PI-G scales in their static form can be recommended for use in German-speaking countries. Their strengths versus the ODI and PDI are that pain interference is assessed in a differentiated manner and that several psychometric values are somewhat better than those associated with the ODI and PDI (distribution properties, IRT model fit, reliability). To develop an IRT-scaled item bank of the German translations of the PROMIS(®) PI items, it would be useful to have additional studies (e.g., with larger sample sizes and using a 2-parameter IRT model).

Review Meta Analysis
Oral Chinese herbal medicine for improvement of quality of life in patients with chronic heart failure: a systematic review and meta-analysis.
Chronic heart failure (CHF) is not only a leading cause of death, hospitalization, and rehospitalization, but also significantly decreases quality of life (QoL). This study aims to evaluate published clinical trials of oral Chinese herbal medicine (OCHM) for improvement of QoL in patients with CHF that employ the Minnesota Living with Heart Failure Questionnaire (MLHFQ) score as an outcome measure. ⋯ There is some encouraging evidence of OCHM combined with CMT for the improvement of QoL in CHF patients. However, the evidence remains weak due to the small sample size, high clinical heterogeneity, and poor methodological quality of the included trials. Further, large sample size and well-designed trials are needed.

Comparative Study
Psychometric properties of the PROMIS ® pediatric scales: precision, stability, and comparison of different scoring and administration options.
The objectives of the present study are to investigate the precision of static (fixed-length) short forms versus computerized adaptive testing (CAT) administration, response pattern scoring versus summed score conversion, and test-retest reliability (stability) of the Patient-Reported Outcomes Measurement Information System (PROMIS(®)) pediatric self-report scales measuring the latent constructs of depressive symptoms, anxiety, anger, pain interference, peer relationships, fatigue, mobility, upper extremity functioning, and asthma impact with polytomous items. ⋯ The study provides further information on the psychometric properties of the PROMIS pediatric scales and extends the previous IRT analyses to include precision estimates of dynamic versus static administration, test-retest reliability, and validity of administration across groups. Both the positive and negative aspects of using CAT versus short forms are highlighted.
