Observational Study
Survival and functional outcomes of patients with metastatic solid organ cancer admitted to the intensive care unit of a tertiary centre.
Metastatic solid organ cancer is associated with a poor prognosis, and admission of patients with these cancers to the intensive care unit remains a dilemma. We aimed to assess outcomesin a cohort of these patients who were admitted to the ICU of a general tertiary centre. ⋯ Survival is poor in patients with metastatic cancer after emergent ICU admission, although functional state is often recovered by 3 months in surviving patients. Albumin level, white cell count and ECOG grade are simple prognostic markers of survival.

Olfactory dysfunction in neurodegenerative diseases: is there a common pathological substrate?
In patients with neurodegenerative diseases, there is a spectrum of smell dysfunction ranging from severe loss, as seen in Alzheimer's disease and Parkinson's disease, to relatively little loss, as seen in progressive supranuclear palsy. Given the ubiquitous but varying degrees of olfactory dysfunction among such diseases, it is conceivable that differential disruption of a common primordial neuropathological substrate causes these differences in olfactory function. ⋯ Thus, a key question is whether damage to such a substrate is the basis for the perceptual differences in olfaction or whether disease-specific or other entities, such as respiratory infections or pollution, are responsible. In light of the early preclinical onset of smell deficits in many neurodegenerative diseases, the answer to this question might provide crucial insight into the cause of disease pathology at its earliest stages of development.

Complex regional pain syndrome (CRPS) is a persistent pain condition that remains incompletely understood and challenging to treat. Historically, a wide range of different outcome measures have been used to capture the multidimensional nature of CRPS. This has been a significant limiting factor in the advancement of our understanding of the mechanisms and management of CRPS. ⋯ The domains encompassing the key concepts necessary to answer the research question were agreed as follows: pain, disease severity, participation and physical function, emotional and psychological function, self-efficacy, catastrophizing, and patient's global impression of change. The final core measurement set included the optimum generic or condition-specific patient-reported questionnaire outcome measures, which captured the essence of each domain, and 1 clinician-reported outcome measure to capture the degree of severity of CRPS. The next step is to test the feasibility and acceptability of collecting outcome measure data using the core measurement set in the CRPS population internationally.

Effective assessment and management of pain in patients with cancer is strengthened by the patient's report of how much pain interferes with daily functioning. This requires a clear delineation of different levels of pain interference. We derived optimal cutpoints for differentiating between mild, moderate, and severe pain interference assessed by the Brief Pain Inventory (BPI) and describe the prevalence and characteristics of pain-induced functional impairment in patients with cancer. ⋯ The mild (<2), moderate (2-5 or 2-6), and severe (>5 or >6) pain interference groups were significantly concordant with ECOG-PS levels (P < 0.0001). We empirically derived patient-reported pain interference categories in relation to clinician-rated performance status. These cutpoints may facilitate the conduct and interpretation of clinical evaluation, symptom epidemiology, and clinical trials.

Provoked vestibulodynia (PVD) and painful bladder syndrome (PBS), subgroups of chronic pelvic pain syndromes (CPPS), are considered to share common biophysiological peripheral mechanisms. In addition, indications of a pronociceptive pain profile coexisting with psychological vulnerability suggest common dysfunctional pain processing and pain modulation in these 2 subgroups of CPPS. We therefore aimed at comparing the pain profile and psychological traits of patients with PVD and PBS to see whether the pain profile contributes to intersubject variability of clinical pain symptoms. ⋯ The latter was also correlated with pain catastrophizing (r = 0.504, P = 0.001) and depression symptoms (r = 0.361, P = 0.024). The findings suggest common mechanisms underlying a dysfunctional nociceptive system in both PVD and PBS. The intersubject variability in the level of dysfunction and its association with disease severity recommends a personalized pain treatment that may alleviate daily pain and dysfunction in patients with CPPS.
