PROBLEM: Context: This study was designed to examine the course of psychological distress and pain from study entry to death in 59 women with metastatic breast cancer participating in a randomized trial of the effects of group psychotherapy on psychosocial outcomes and survival. It was hypothesized that psychological distress would increase significantly before death independent of changes in pain.', 'Data were collected as part of a larger study (N = 125). Analyses were based on data from a subset of women who had died and for whom we had data from at least three assessments. Mean levels of mood, trauma symptoms, depression symptoms, well-being, and pain over three time points were examined: at baseline (T1), the second-to-last assessment before death (T2), and the last assessment before death (T3).', 'Results indicate that while psychological distress remained relatively constant or declined from T1 to T2, means on all measures significantly changed in the hypothesized direction from T2 to T3. Neither self-reported pain, nor the passage of time, appeared to account for these changes. Additionally, participation in group psychotherapy did not have a significant impact on this change in distress proximal to death.
Answer: Results suggest that specialized end-stage clinical interventions are particularly needed for cancer patients as they approach death. Moreover, intervention studies for patients with deteriorating illnesses may need to take this "spike" in psychological distress and pain proximal to death into account to avoid Type II errors in evaluations of psychological outcomes.

SOLUTION: Do psychological distress and pain significantly increase before death in metastatic breast cancer patients?

PROBLEM: Context: Although Alzheimer's disease (AD) is associated with early death, its life expectancy differs greatly between patients. A better understanding of this heterogeneity may reveal important disease mechanisms underlying the malignancy of AD. The aim of this study was to examine the relation between AD pathologies and early death in AD caused by dementia.", 'At a memory clinic, 247 referred consecutive patients with AD were monitored during 12.6\u2009±\u20091.6 years. Multivariate Cox regression analyses were performed with baseline measures of amyloid beta (Aβ) pathology (APOE genotype, cerebrospinal fluid (CSF) Aβ42) tau pathology (CSF phosphorylated tau and total tau), cerebrovascular pathology (white-matter lesions and CSF/serum albumin ratio), neuroinflammatory pathology (CSF soluble vascular cell adhesion molecule-1, sVCAM-1), frontal, temporal, and central brain atrophies, global cognition, sex, and age. Comorbidities and medications also were analyzed. All continuous variables were transformed to z scores to compare hazard ratios (HRs) and 95% confidence intervals (CIs).', 'At follow-up, 89% of the patients had died. The mean survival time was 6.4\u2009±\u20093.0 years. The AD pathology that independently predicted an early death caused by dementia was cerebral inflammation (sVCAM-1; HR, 1.32; 95% CI, 1.07-1.64). Other independent predictors were lower global cognition (HR, 0.51; 95% CI, 0.43-0.61), frontal atrophy (HR, 1.38; 95% CI, 1.12-1.70), and medial temporal atrophy (HR, 1.23; 95% CI, 1.02-1.49). When examining death caused by dementia and related causes (vascular diseases and infections), age (HR, 1.23; 95% CI, 1.04-1.46) and cerebrovascular pathology (white-matter lesions: HR, 1.17; 95% CI, 1.01-1.36; and CSF/serum albumin ratio: HR, 1.16; 95% CI, 1.001-1.34) were also significant risk factors in addition to the previous variables. No comorbidity or medication was significant in the specific-cause models.
Answer: This is the first study to link neuroinflammation independently to early death in AD and, hence, a rapidly progressing disease. Frontal and medial temporal atrophies and low cognition were also significant predictors. These are probably downstream biomarkers that reflect neuronal degeneration and late-stage disease. Our results suggest that inflammation, and not amyloid or tau pathology, is an independent underlying mechanism in the malignancy of AD.

SOLUTION: Is cerebral inflammation an underlying mechanism of early death in Alzheimer 's disease : a 13-year cause-specific multivariate mortality study?

PROBLEM: Context: Congenital glaucoma is primarily a surgical disease with medical management serving as a temporizing measure before surgery or as postoperative adjunctive treatment. First-line surgery for congenital glaucoma consists of incisional procedures on the anterior chamber angle: goniotomy and trabeculotomy. Angle surgery has a high success rate with few complications. Despite the high initial success rate, almost 20% of angle procedures eventually fail, and surgeons are confronted with a choice of what procedure to do next: a trabeculectomy with or without adjunctive antifibrosis therapy, glaucoma drainage surgery, or cyclodestructive procedures. This review will discuss and compare these procedures as reported in recent studies and how variables such as age, number of prior procedures, and type of glaucoma have clarified the order in which these procedures might be performed after failed angle surgery.', 'Clinical reports in refractory pediatric glaucoma consist solely of retrospective studies of varying size and quality. Recent studies of trabeculectomy in this population suggest mitomycin C is associated with increased risk of late infectious complications. Trabeculectomy has worse outcome among younger patients Glaucoma drainage devices have a success rate approaching 80% at 1 year, but less with longer follow-up. Cyclodestructive procedures are generally reserved for advanced cases, but low-dose cyclodiode therapy and endocyclophotocoagulation may prove useful earlier in the disease (< 2 years).
Answer: Refractory pediatric glaucoma remains a challenge. Glaucoma drainage devices appear to be the most predictable and possibly safest procedure to consider after failed conventional angle surgery.

SOLUTION:
Does options in pediatric glaucoma after angle surgery have failed?
