RESUMO
PURPOSE: To summarize the scientific evidence that compassion can measurably improve patient outcomes, health care quality and safety, and the well-being of health care providers, and to consider specific strategies for cultivating compassion and better communicating it to patients. DESIGN: Perspective. METHODS: We selectively reviewed the literature on compassion in health care, including obstacles to its expression and the demonstrated effects of provider compassion on patient outcomes, health care quality and cost, and provider well-being. We also review evidence regarding the trainability of compassion, discuss proven methods for cultivating individual compassion, and recommend strategies for incorporating it into routine medical practice. RESULTS: Compassion is the emotional response to another's pain or suffering, accompanied by a desire to alleviate it. Review of the literature shows that compassionate health care measurably improves physical and psychological patient outcomes, increases patient adherence, improves health care quality and safety, increases financial margins, and prevents physician burnout. Psychophysiological research shows that empathy and compassion can be actively cultivated through intentional practice. Validated models of compassion-based interactions can facilitate the consistent expression of compassion in daily medical practice. CONCLUSIONS: Given its many proven benefits to patients, health care organizations, and providers, compassion should be cultivated by health care providers and systems and considered an essential component of optimal medical care.

ABSTRACT: Infectious keratitis is a devastating cause of vision loss worldwide. Cutibacterium acnes ( C. acnes ), a commensal bacterium of the skin and ocular surface, is an underrecognized but important cause of bacterial keratitis. This review presents the most comprehensive and up-to-date information for clinicians regarding the risk factors, incidence, diagnosis, management, and prognosis of C. acnes keratitis (CAK). Risk factors are similar to those of general bacterial keratitis and include contact lens use, past ocular surgery, and trauma. The incidence of CAK may be approximately 10%, ranging from 5% to 25% in growth-positive cultures. Accurate diagnosis requires anaerobic blood agar and a long incubation period (≥7 days). Typical clinical presentation includes small (<2 mm) ulcerations with deep stromal infiltrate causing an anterior chamber cell reaction. Small, peripheral lesions are usually resolved, and patients recover a high visual acuity. Severe infections causing VA of 20/200 or worse are common and often do not significantly improve even after treatment. Vancomycin is considered the most potent antibiotic against CAK, although other antibiotics such as moxifloxacin and ceftazidime are more commonly used as first-line treatment.

The type IV pilus (Tfp) of nontypeable Haemophilus influenzae (NTHI) mediates adherence, colonization, motility, and biofilm formation, and the major protein subunit, PilA, is a promising vaccine candidate. Thus, it is crucial to understand how Tfp expression is regulated within the microenvironments of the human nasopharynx, which NTHI colonizes asymptomatically, and the more distal regions of the respiratory tract where NTHI-induced diseases occur. Here, we examined the effects of coculture of NTHI with human airway epithelial cells and heme availability on Tfp expression at temperatures typical of the human nasopharynx (34°C) or warmer anatomical sites during infection (37°C). Tfp expression was estimated by pilA promoter activity, pilA gene expression, and relative abundances of PilA and pilin protein. The results revealed that at both temperatures, NTHI cocultured with airway epithelial cells demonstrated significantly greater expression of pilA, PilA/pilin protein, and likely, fully assembled Tfp than NTHI cultured on an abiotic surface. Because NTHI is a heme auxotroph, we hypothesized that availability of heme from host cells might be a signal for Tfp expression. Thereby, we cultured NTHI in iron-limited medium, and we observed that supplementation with heme significantly increased pilA promoter activity. Collectively, our data suggested that NTHI Tfp expression was stimulated by soluble factor(s) released by epithelial cells, which are present in all microenvironments of the respiratory tract. The expression of this target antigen under conditions that mimic the human airway strongly supports the rationale for the use of PilA as a vaccine immunogen to prevent NTHI-induced diseases of the respiratory tract.
