Survivors of critical illness often experience long-lasting impairments in mental, cognitive, and physical functioning. Acute stress reactions and delusional memories appear to play an important role in psychological morbidity following critical illness, and few interventions exist to address these symptoms. This review elucidates acute psychological stressors experienced by the critically ill. ⋯ Memory may play a role in the genesis of subsequent psychological trauma. Traumatic memories may begin forming even before the patient arrives in the ICU and during their state of unconsciousness in the ICU. Hence, practical interventions for redirecting patients' thoughts, such as positive suggestion techniques and actively involving patients in the treatment process as early as possible, are worthy of further investigation.

Over the past 30 years, therapeutic advances have extended the median lifespan of patients with cystic fibrosis (CF). Hispanic patients are a vulnerable subpopulation with a high prevalence of risk factors for worse health outcomes. The consequences of these differences on health outcomes have not been well described. The objective of this study was to characterize the difference in health outcomes, including mortality rate, between Hispanic and non-Hispanic patients with CF. ⋯ Hispanic patients with CF have a higher mortality rate than do non-Hispanic patients, even after adjusting for socioeconomic status and clinical severity. Further investigation into the mechanism for the measured difference in lung function will help inform interventions and improve the health of all patients with CF.

Association between sensory dysfunction and pain 1 week after breast cancer surgery: a psychophysical study.
Breast cancer patients treated with axillary lymph node dissection (ALND) have a higher risk of both acute and persistent pain than those treated with sentinel lymph node biopsy (SLNB). This could be attributed to a higher risk of nerve injury with ALND. We hypothesized that (1) pain patients have more pronounced sensory dysfunction than pain-free patients, (2) ALND have more sensory dysfunction and pain than SLNB patients and (3) patients with preserved intercostobrachial nerve (ICBN) preservation have less sensory dysfunction compared to a sectioned ICBN. ⋯ Pain was increased in patients having larger areas of hypoaesthesia and reduced in patients where ICBN-section was done. Sensory dysfunction was related to extent of axillary surgery, but not with ICBN handling. Our data suggest that acute pain after breast cancer surgery may be related to nerve injury.

Pain can be modulated by contextual stimuli, such as emotions, social factors, or specific bodily perceptions. We presented painful laser stimuli together with body-related masochistic visual stimuli to persons with and without preferred masochistic sexual behavior and used neutral, positive, and negative pictures with and without painful stimuli as control. Masochists reported substantially reduced pain intensity and unpleasantness in the masochistic context compared with controls but had unaltered pain perception in the other conditions. ⋯ Masochists additionally showed negative correlations between the duration of interest in masochistic activities and activation of areas involved in motor activity and affective processing. We propose that the parietal operculum serves as an important relay station that attenuates the affective-motivational aspects of pain in masochists. This novel mechanism of pain modulation might be related to multisensory integration and has important implications for the assessment and treatment of pain.
