OBJECTIVES: Histologic remission is a potentially valuable means of assessing disease activity and treatment response in ulcerative colitis (UC). However, the efficacy of existing therapies to achieve this outcome is unclear. We performed a systematic review and meta-analysis of histologic outcomes in UC randomized controlled trials and examined the relationship between histologic and endoscopic outcomes. METHODS: MEDLINE, EMBASE, CENTRAL, and the Cochrane IBD Register were searched for randomized controlled trials of aminosalicylates, corticosteroids, immunosuppressives, biologics, and small molecules. Histologic and endoscopic remission and response data were independently extracted and pooled using binomial–normal random-effect or fixed-effect models. Pooled efficacy estimates were calculated as risk ratios (RRs) using the Mantel–Haenszel method. Univariable and multivariable random-effect meta-regression models examined factors associated with histologic remission. RESULTS: Seventy-four studies (68 induction and 7 maintenance) were identified. Topical aminosalicylate enemas [37.2%, 95% confidence interval (CI), 29.0–46.3] and suppositories (44.9%, 95% CI, 28.9–62.3) had the highest induction of histologic remission rates. Aminosalicylate enemas (RR = 4.14, 95% CI, 2.35–7.31), aminosalicylate suppositories (RR = 3.94, 95% CI, 1.26–12.32), and budesonide multimatrix (RR = 1.47, 95% CI 1.08–1.99) had higher histologic remission rates than placebo. Data were lacking for biologics and immunosuppressives. The pooled histologic remission rate for placebo in induction studies was 10.4% (95% CI, 7.1–15.2). Histologic and endoscopic remission correlated strongly ( r = 0.66; 95% CI, 0.50–0.78). In multivariate analysis of placebo-arm data, less severe clinical disease activity and corticosteroid use were associated with higher histologic remission rates. Similarly, mild clinical disease activity was associated with higher histologic remission rates when active-arm data were analyzed. CONCLUSIONS: Histologic remission rates for current UC treatments ranged from 15.0% to 44.9% according to drug class and patient population with the highest rates observed for topical aminosalicylates. Placebo remission rates were low with relatively narrow CIs. These data provide benchmarks to inform future trial design. Histologic remission is a potential treatment target in clinical practice.

ABSTRACTAimPatients with autosomal dominant polycystic kidney disease (ADPKD) are at increased risk of premature mortality, morbidities and complications, which severely impair quality of life. However, patient‐centered outcomes are not consistently reported in trials in ADPKD, which can limit shared decision‐making. We aimed to identify outcomes important to patients and caregivers and the reasons for their priorities.MethodsNominal group technique was adopted involving patients with ADPKD and caregivers who were purposively selected from eight centres across Australia, France and the Republic of Korea. Participants identified, ranked and discussed outcomes for trials in ADPKD. We calculated an importance score (0–1) for each outcome and conducted thematic analyses.ResultsAcross 17 groups, 154 participants (121 patients, 33 caregivers) aged 19 to 78 (mean 54.5 years) identified 55 outcomes. The 10 highest ranked outcomes were: kidney function (importance score 0.36), end‐stage kidney disease (0.32), survival (0.21), cyst size/growth (0.20), cyst pain/bleeding (0.18), blood pressure (0.17), ability to work (0.16), cerebral aneurysm/stroke (0.14), mobility/physical function (0.12), and fatigue (0.12). Three themes were identified: threatening semblance of normality, inability to control and making sense of diverse risks.ConclusionFor patients with ADPKD and their caregivers, kidney function, delayed progression to end‐stage kidney disease and survival were the highest priorities, and were focused on achieving normality, and maintaining control over health and lifestyle. Implementing these patient‐important outcomes may improve the meaning and relevance of trials to inform clinical care in ADPKD.

Individuals with aphasia experience impairments in communication that can be exacerbated by environmental and task demands. This investigation examined the interaction between physical-demands, social-engagement, and environment. An interdisciplinary team, including speech language pathologists and a kinesiologist measured the activities of individuals with aphasia at the Chippewa Valley Aphasia Camp. Accelerometers were used to measure degree of physical exertion as an indication of physical demands. The Clinical Discourse Assessment (Damico, 1991), Measure of Participation in Conversation and Measure of Skill in Supported Conversation (Kagan et al., 2004), qualitative analyses, and investigator field notes served as indicators of social engagement. The International Classification of Disease Functioning (ICF) was used to code environmental factors, which either served as a facilitator or barrier to participation. Qualitative analyses indicate that the presence of physical environmental barriers and more strenuous physical exertion sometimes serve to decrease social engagement and exchange. However, partners who served as facilitators enabled participants to overcome high environmental and/or physical task demands to support successful social engagement and exchange. These analyses suggest that participants with aphasia can overcome physical environmental barriers and/or high physical task demands, given effective partner supports. This investigation contributes to a small body of research regarding the interaction between environmental demands and social communication among individuals with aphasia. Further, the investigation contributes empirical information about the environment and social communication context of a rustic Aphasia Camp.

Considering an increase in the life expectancy leading to a rise in the elderly population, it is important to recognize the changes that occur along the process of aging. Gastrointestinal (GI) changes in the elderly are common, and despite some GI disorders being more prevalent in the elderly, there is no GI disease that is limited to this age group. While some changes associated with aging GI system are physiologic, others are pathological and particularly more prevalent among those above age 65 years. This article reviews the most important GI disorders in the elderly that clinicians encounter on a daily basis. We highlight age-related changes of the oral cavity, esophagus, stomach, small and large bowels, and the clinical implications of these changes. We review epidemiology and pathophysiology of common diseases, especially as they relate to clinical manifestation in elderly. Details regarding management of specific disease are discussed in detail if they significantly differ from the management for younger groups or if they are associated with significant challenges due to side effects or polypharmacy. Cancers of GI tract are not included in the scope of this article.

Background. Systemic inflammation in colorectal cancer (CRC) may be reflected by neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume (MPV). This study was designed to investigate the efficiency of preoperative NLR, PLR, and MVP as a tool for the assessment of tumor characteristics in newly diagnosed patients with CRC. Patients and Methods. For 300 patients and 300 healthy volunteers, complete blood counts with automated differential counts were performed. The NLR was calculated by dividing the absolute neutrophil count by the absolute lymphocyte count; PLR was calculated by dividing the absolute platelet count by the absolute lymphocyte count. The diagnostic performance of NLR, PLR, and MVP was estimated by ROC curve. Results. ROC curve analysis showed high diagnostic efficacy of NLR and PLR in CRC patients with cut-off values of 2.15 (AUC=0.790, 95% CI 0.736-0.884, Se=74.1%, and Sp=73%) and 123 (AUC=0.846, 95% CI 0.801-0.891, Se=73.5%, and Sp=80%) compared to healthy controls, respectively. The diagnostic efficacy of three combined markers was superior compared with individual markers (AUC=0.904, 95% CI 0.812-0.989, Se=96%, and Sp=70%). Conclusion. NRL, PLR, and MPV may be useful markers in diagnostic and early recognition of different stages of CRC; additionally combined all together have stronger diagnostic efficacy.
