Background And Aims: The declining global prevalence of peptic ulcer disease (PUD) might be because of the decreasing prevalence of Helicobacter pylori (Hp) infection. The aims of the present study were to determine the prevalence of PUD during a 7-year period and to investigate its relationship with the prevalence of Hp infection during the same period.
Methods: All upper gastrointestinal endoscopies carried out at Santo Tomas Hospital in Manila from January 1996 to December 2002 were evaluated. Endoscopies reporting gastric ulcers (GU) and duodenal ulcers (DU) with Hp status were analyzed.
Results: A total of 15 341 endoscopies were evaluated. Overall, 2600 (16.95%) GU and 1575 (10.27%) DU were identified. There was a decreasing trend in the prevalence of GU (P < 0.0001) and DU (P < 0.0001) during the study period. Overall PUD prevalence declined from 35.87% in 1996 to 18.80% in 2002. This decline was seen for both GU and DU (20.05 vs 14.34%, and 15.83 vs 7.02%, respectively). The prevalence of Hp infection decreased significantly from 1996 to 2002 for both GU and DU (68.13 vs 33.48%, P < 0.0001; and 76.67 vs 36.50%, P < 0.0001, respectively). The decrease in Hp prevalence was significantly related to the decrease in ulcer prevalence (r = 0.97, P = 0.0004 for GU; r = 0.89, P = 0.0079 for DU; and r = 0.92, P = 0.0035 for all PUD). The prevalence of bleeding secondary to PUD remained stable during the 7-year period (P = 0.87).
Conclusions: During the 7-year period, there was a significant decline in the prevalence of PUD. This decline in PUD prevalence was associated with a corresponding decrease in Hp prevalence.

Background: Pharmacoepidemiologic studies assessing drug effectiveness for Alzheimer's disease and related dementias (ADRD) are increasingly popular given the critical need for effective therapies for ADRD. To meet the urgent need for robust dementia ascertainment from real-world data, we aimed to develop a novel algorithm for identifying incident and prevalent dementia in claims.
Method: We developed algorithm candidates by different timing/frequency of dementia diagnosis/treatment to identify dementia from inpatient/outpatient/prescription claims for 6,515 and 3,997 participants from Visits 5 (2011-2013; mean age 75.

Background: The presence of multiple comorbid pathologic features in late-onset dementia has been well documented across cohort studies that incorporate autopsy evaluation. It is likely that such mixed pathology potentially confounds the results of interventional trials that are designed to target a solitary pathophysiologic mechanism in Alzheimer's disease and related dementias (ADRD).
Method: The UK ADRC autopsy database was screened for participants who had previously engaged in therapeutic interventional trials for Alzheimer's disease, vascular cognitive impairment, dementia, and/or ADRD prevention trials from 2005 to the present.
Background: There is an urgent need for new therapeutic and diagnostic targets for Alzheimer's disease (AD). Dementia afflicts roughly 55 million individuals worldwide, and the prevalence is increasing with longer lifespans and the absence of preventive therapies. Given the demonstrated heterogeneity of Alzheimer's disease in biological and genetic components, it is critical to identify new therapeutic approaches.

However, the clinically meaningful size and mechanism-of-actions of sildenafil in potential prevention and treatment of AD remind unknown.
Method: We conducted new patient data analyses using both the MarketScan® Medicare with Supplemental database (n = 7.
Background: Clinical trial sponsors rely on research sites to identify and enroll appropriate study participants and to correctly and reliably assess symptom severity and function over the course of the trial. Low-recruiting sites represent a large financial and operational burden and may negatively impact trial success either by selecting inappropriate participants and/or high prevalence of data quality issues. We previously reported that >60% of sites in schizophrenia clinical trials recruited ≤5 participants.
