Prominent publications by William Lee Hasler

KOL-Index: 14848 . BACKGROUND: Patients with scleroderma may have abnormal motility of the small intestine, with pseudoobstruction and bacterial overgrowth. Standard stimulatory agents are often ineffective in such patients. Because the somatostatin analogue octreotide evokes intestinal motor activity in normal subjects, we hypothesized that it might increase motility in patients with scleroderma. METHODS: ...

KOL-Index: 12884 . In vivo drug dissolution in the gastrointestinal (GI) tract is largely unmeasured. The purpose of this clinical study was to evaluate the in vivo drug dissolution and systemic absorption of the BCS class IIa drug ibuprofen under fed and fasted conditions by direct sampling of stomach and small intestinal luminal content. Expanding current knowledge of drug dissolution in vivo will help to ...

KOL-Index: 12200 . BACKGROUND & AIMS: Colonic transit time (CTT) traditionally is assessed with radiopaque markers (ROMs), which requires radiation and is hindered by lack of standardization and compliance. We assessed regional and CTT with the SmartPill (SmartPill Corporation, Buffalo, NY), a new wireless pH and pressure recording capsule, in constipated and healthy subjects and compared this with ...

KOL-Index: 11531 . BACKGROUND & AIMS: Idiopathic gastroparesis (IG) is a common but poorly understood condition with significant morbidity. We studied characteristics of patients with IG enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium Registry. METHODS: Data from medical histories, symptom questionnaires, and 4-hour gastric emptying ...

KOL-Index: 11511 . BACKGROUND & AIMS: It is a challenge to make a diagnosis of gastroparesis. There is good agreement in results from wireless motility capsule (WMC) analysis and gastric emptying scintigraphy (GES), but the diagnostic yield of WMC is unclear and the accuracy of this method has not been validated. We compared the performance characteristics of WMC vs GES in assessing gastric emptying in ...

KOL-Index: 11289 . BACKGROUND & AIMS: There are few effective treatments for nausea and other symptoms in patients with gastroparesis and related syndromes. We performed a randomized trial of the ability of the neurokinin-1 receptor antagonist aprepitant to reduce symptoms in patients with chronic nausea and vomiting caused by gastroparesis or gastroparesis-like syndrome. METHODS: We conducted a 4-week ...

KOL-Index: 10943 . BACKGROUND & AIMS: Gastroparesis can be diabetic or idiopathic, yet little is known about differences in their presentation. We compared clinical characteristics, symptoms, and gastric emptying in patients with type 1 or type 2 diabetic (DG) or idiopathic (IG) gastroparesis. METHODS: We analyzed data from 416 patients with gastroparesis who were enrolled in the National Institute of ...

KOL-Index: 10742 . Relationships of regional colonic motility to transit in health, constipation, and constipation-predominant irritable bowel syndrome (C-IBS) are poorly characterized. This study aimed to 1) characterize regional differences in colon pressure, 2) relate motor differences in constipation to colon transit, and 3) quantify the role of IBS in altered contractility with constipation. Colon pH ...

KOL-Index: 10741 . BACKGROUND: Nausea and vomiting are classic symptoms of gastroparesis. It remains unclear if characteristics of nausea and vomiting are similar in different etiologies of gastroparesis. The aims of this article were as follows: to describe characteristics of nausea and vomiting in patients with gastroparesis and to determine if there are differences in nausea and vomiting in diabetic (DG) ...

KOL-Index: 10640 . BACKGROUND: Gastric emptying scintigraphy (GES) using a radio-labelled meal is used to measure gastric emptying. A nondigestible capsule, SmartPill, records luminal pH, temperature, and pressure during gastrointestinal transit providing a measure of gastric emptying time (GET). AIMS: To compare gastric emptying time and GES by assessing their correlation, and to compare GET and GES for ...

KOL-Index: 10524 . Impaired fundic accommodation (FA) limits fundic relaxation and the ability to act as a reservoir for food. Assessing intragastric meal distribution (IMD) during gastric emptying scintigraphy (GES) allows for a simple measure of FA. The 3 goals of this study were to evaluate trained readers' (nuclear medicine and radiology physicians) visual assessments of FA from solid-meal GES; develop ...

KOL-Index: 10394 . BACKGROUND: Early satiety (ES) and postprandial fullness (PPF) are often present in gastroparesis, but the importance of these symptoms in gastroparesis has not been well-described. The aims were: (i) Characterize ES and PPF in patients with gastroparesis. (ii) Assess relationships of ES and PPF with etiology of gastroparesis, quality of life, body weight, gastric emptying, and water load ...

KOL-Index: 10317 . BACKGROUND: The wireless motility capsule (WMC) offers the ability to investigate luminal gastrointestinal (GI) physiology in a minimally invasive manner. AIM: To investigate the effect of testing protocol, gender, age and study country on regional GI transit times and associated pH values using the WMC. METHODS: Regional GI transit times and pH values were determined in 215 healthy ...

KOL-Index: 10118 . BackgroundThe prevalence of generalized transit delay and relation to symptoms in suspected gastroparesis, intestinal dysmotility, or slow transit constipation are unknown.AimsThe aims of this study were (1) to define prevalence of generalized dysmotility using wireless motility capsules (WMC), (2) to relate to symptoms in suspected regional delay, (3) to compare results of WMC testing to ...

KOL-Index: 10057 . In this study, we determined the pH and buffer capacity of human gastrointestinal (GI) fluids (aspirated from the stomach, duodenum, proximal jejunum, and mid/distal jejunum) as a function of time, from 37 healthy subjects after oral administration of an 800 mg immediate-release tablet of ibuprofen (reference listed drug; RLD) under typical prescribed bioequivalence (BE) study protocol ...
