Numerous, sometimes conflicting, changes in brain functional connectivity have been associated with the transition from wakefulness to unresponsiveness at induction of general anesthesia. However, relatively few studies have looked at the detailed time evolution of the transition, for different electroencephalogram (EEG) frequency bands, and in the clinical scenario of surgical patients undergoing general anesthesia. ⋯ Propofol-induced loss of consciousness in surgical patients is associated with a global breakdown in low-frequency directed functional connectivity, coupled with a high-frequency increase between closely located brain regions. At loss of consciousness, Granger causality shows more pronounced changes than coherence.

Anti-inflammatory and anti-cancer effects of polysaccharides from Antrodia cinnamomea: A review.
Antrodia cinnamomea ( Ac ), also known as "Niu-Chang-Chih" in Chinese, is a valuable fungus that has been widely used as medicine and food among indigenous people in Taiwan. Ac is rich in polysaccharides ( Ac -PS), making it a promising candidate for adjunctive therapy in cancer and inflammation conditions. There are two types of Ac -PS: general (non-sulfated) PS ( Ac -GPS) and sulfated PS ( Ac -SPS). ⋯ Clinically, Ac -GPS has been used as an adjunctive therapy for advanced lung cancer, as noted in recent reports. However, given the numerous studies emphasizing its anticancer mechanisms, Ac -SPS may exhibit greater efficacy, warranting further investigation. This review concludes that Ac -derived Ac -GPS or Ac -SPS have the potential to be developed into functional health supplements or adjunctive therapies, providing dual benefits of anti-inflammatory and anticancer effects.

Chronic pain is a global health concern and often interferes with multiple aspects of individuals' lives (eg, physical activities), diminishing a person's ability to engage in activities that promote meaning in life. However, it is not well understood how believing that one can live a meaningful life despite pain could contribute to improved function among individuals with chronic pain. The aim of the present study was to better understand the role that belief in living a meaningful life despite pain might have on adjustment to chronic pain. ⋯ Results provide important theoretical and clinical information about how believing that one can live a meaningful life despite pain might serve as an important process for adjustment to chronic pain.

The study aimed to assess the relationship between the Fit fOR The Aged (FORTA) score - a classification system designed to evaluate medication appropriateness in older adults - and several negative outcomes, including impaired cognitive performance, functional status, adverse clinical events, and all-cause mortality at 3, 6, and 12 months after hospital discharge. ⋯ The study did not find a significant relationship between the FORTA score and negative outcomes in older patients discharged from internal medicine and geriatric wards. Further research is needed to define specific FORTA score cut-off values and expand the criteria to improve medication assessment in this population.

Association Between Preoperative Anemia and Cognitive Function in a Large Cohort Study of Older Patients Undergoing Elective Surgery.
The etiology of anemia has tremendous overlap with the disease states responsible for cognitive decline. We used data from a perioperative database of older adults undergoing elective surgery with anesthesia to (1) examine relationships among preoperative anemia blood markers, preoperative screeners of cognitive function, and chronic disease status; and (2) examine the relationship of these factors with operative outcomes. The primary goal of this study was to investigate the association between preoperative anemia blood markers and cognition measured by a preoperative cognitive screener. Secondary goals were to (1) examine the relationship between preoperative anemia blood markers and chronic disease states (ie, American Society of Anesthesiologists [ASA] and frailty), and (2) investigate the relationship of preoperative anemia blood markers and cognition with operative outcomes (ie, discharge disposition, 1-year mortality, number of surgical complications, length of hospital stay, and length of intensive care unit [ICU] stay). ⋯ In this first medicine study, we established relationships among anemia, preoperative markers of frailty and cognition, and chronic disease states in a large cohort of older patients undergoing elective surgery in a large tertiary medical center. We found that anemia, cognitive vulnerability, and chronic health disease states predicted death within 1 year of surgery, and that these preoperative factors negatively contribute to surgical outcomes such as time in the ICU, length of hospital stay, nonhome discharge, and 1-year mortality. The World Health Organization (WHO) and many academic medical societies have urged the adoption of patient blood management (PBM) disciplines, yet anemia is not routinely optimized as a preoperative risk factor. Given the well-defined association between preoperative anemia and postoperative morbidity and mortality, performing elective surgery on an untreated anemic patient should be considered substandard care. With established safe and effective treatment regimens, iron deficiency anemia is a modifiable preoperative risk factor that should be addressed before elective surgery.
