We introduce a new instrument to evaluate the impact of behavior on outcomes when the behavior may be a function of unobserved variables that also affect outcomes. The instrument is introduced through a test of patient sensitivity to increases in the quality of care provided by doctors. We utilize the Hawthorne effect, in which the very presence of a research team causes doctors to provide measurably superior quality care for any type of patient to show that patients respond to this increased quality and are more likely to be very satisfied. Using the Hawthorne effect as an instrument allows us to examine the responsiveness of satisfaction to improvements in quality despite the fact that patient satisfaction is subjective and jointly produced with quality during the course of a consultation.

Artificial intelligence (AI), with advantages such as automatic feature extraction and high data processing capacity and being unaffected by fatigue, can accurately analyze images obtained from colonoscopy, assess the quality of bowel preparation, and reduce the subjectivity of the operating physician, which may help to achieve standardization and normalization of colonoscopy. In this study, we aimed to explore the value of using an AI-driven intestinal image recognition model to evaluate intestinal preparation before colonoscopy. In this retrospective analysis, we analyzed the clinical data of 98 patients who underwent colonoscopy in Nantong First People's Hospital from May 2023 to October 2023.

As the face ages, the skin, fat, muscle, and fascia descend, and the underlying bone, cartilage, and teeth may lose mass. Oculofacial aging is a multifactorial process that is influenced by genetic, environmental, and lifestyle factors. This review summarizes the patterns of oculofacial aging that are observed across populations, including variations in periorbital hollowing, eyelid ptosis, and skin elasticity.
