Psychological impacts of intervention to improve a therapeutic garden for older adults with dementia: a case study conducted at a care facility.

Introduction: Exposure to nature is known to support psychological wellbeing, and can support People with Dementia (PwD). Here we describe a case study conducted at a care facility for PwD to examine the effect of their exposure to nature after intervention to renovate an existing Therapeutic Garden (TG). Changes in frequency of attendance and behavior in the TG were examined.

Causal reasoning without mechanism.

Unobservable mechanisms that tie causes to their effects generate observable events. How can one make inferences about hidden causal structures? This paper introduces the domain-matching heuristic to explain how humans perform causal reasoning when lacking mechanistic knowledge. We posit that people reduce the otherwise vast space of possible causal relations by focusing only on the likeliest ones.

Patient-reported quality of life during definitive and postprostatectomy image-guided radiation therapy for prostate cancer.

Purpose: The importance of patient-reported outcomes is well-recognized. Long-term patient-reported symptoms have been described for individuals who completed radiation therapy (RT) for prostate cancer. However, the trajectory of symptom development during the course of treatment has not been well-described in patients receiving modern, image-guided RT.

Role of saliva in esophageal defense: implications in patients with nonerosive reflux disease.

Background: It has been previously demonstrated that patients with reflux esophagitis exhibit a significant impairment in the secretion of salivary protective components versus controls. However, the secretion of salivary protective factors in patients with nonerosive reflux disease (NERD) is not explored. The authors therefore studied the secretion of salivary volume, pH, bicarbonate, nonbicarbonate glycoconjugate, protein, epidermal growth factor (EGF), transforming growth factor alpha (TGF-α) and prostaglandin E2 in patients with NERD and compared with the corresponding values in controls (CTRL).
