Influence of Senna, Fibre, and Fibre + Senna on Colonic Transit in Loperamide-induced Constipation

1993

Retarded colonic transit and disturbed defecation are the most prominent pathophysiological mechanisms in constipation. Both may be influenced by bulking agents and by laxatives such as senna. Direct measurements of the influence of such substances on colonic transit are rare mainly because of technical problems. We measured gastric emptying, small and large intestinal transit in 24 healthy volunteers by a newly developed method employing a metal detector. Twelve persons taking a normal diet received loperamide in a dose sufficient to double the individual transit time. All subjects measured gastrointestinal transit time under normal conditions and with Sennatin containing purified sennosid…

Intraperitoneal drain placement and outcomes after elective colorectal surgery: International matched, prospective, cohort study

2022

Abstract Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and tim…

Between a Rock and Hard Place: Combined Effects of Authentic Leadership, Organizational Identification, and Team Prototypicality on Managerial Prohib…

2019

AbstractManagers are installed by the organization’s stakeholders and shareholders to increase the organization’s value; at the same time, they depend on their subordinates’ acceptance to fulfill this leadership role. If the interest of the organization collides with the interest of their team, some managers act in the interest of their followers accepting potential disadvantages for their organizations and/or external stakeholders. In two experimental studies comprised mainly of German (N = 111) and US (N = 323) managers, we examined combined effects of authentic leadership, organizational identification, and self-perceived team prototypicality on managerial integrity operationalized as ex…

Genetic and environmental factors in health-related behaviors: Studies on Finnish twins and twin families

2003

Family, twin and adoption studies have provided evidence for familial and genetic influences on individual differences in disease risk and in human behavior. Attempts to identify individual genes accounting for these differences have not been outstandingly successful to date, and at best, known genes account for only a fraction of the familiality of most traits or diseases. More detailed knowledge of the dynamics of gene action and of specific environmental conditions are needed. Twin and twin-family studies with multiple measurements of risk factors and morbidity over time can permit a much more detailed assessment of the developmental dynamics of disease risk and the unfolding of behavior…

Soccer players' fitting perception of different upper boot materials.

2016

[EN] The present study assessed the influence of upper boot materials on fitting perception. Twenty players tested three soccer boots only differing in the upper boot material (natural calf leather, natural kangaroo leather and synthetic leather). Players reported fitting perception and preference on specific foot areas using a perceived fitting scale. Ratings were averaged for every foot area. Repeated measures ANOVA was used to analyze the differences between boots. The kangaroo leather boots were perceived tighter and closer to the preferred fitting in general fitting, metatarsals area and instep area. The synthetic leather boots were perceived as the loosest and as the most distant boot…

MRI studies after treatment of brain tumors in childhood and adolescence

1986

Forty-seven children and adolescents with brain tumors were examined by magnetic resonance imaging (MRI) after tumor resection. The typical changes and complications after surgery and chemotherapy, as well as the corresponding MRI findings, are discussed. Typical examples of boundary-layer lesions, tumor recurrences, hydrocephalus, porencephalic cysts, and hygromas are given.

Chronic Thromboembolic Pulmonary Hypertension: Pre- and Postoperative Assessment with Breath-hold MR Imaging Techniques

2004

To evaluate the potential of breath-hold magnetic resonance (MR) imaging techniques in morphologic and functional assessment of patients with chronic thromboembolic pulmonary hypertension (CTEPH) before and after surgery.Thirty-four patients with CTEPH were examined before and after pulmonary thromboendarterectomy (PTE). For morphologic assessment, contrast material-enhanced MR angiography was used; for assessment of hemodynamics, velocity-encoded gradient-echo sequences and cine gradient-echo sequences along the short axis of the heart were performed. Contrast-enhanced MR angiography was compared with selective digital subtraction angiography (DSA) for depiction of central thromboembolic m…

The phenotype of gastric mucosa coexisting with Barrett's oesophagus.

2001

Barrett's oesophagus complicates the gastro-oesophageal acid reflux. Helicobacter pylori infection, particularly with cagA positive strains, induces inflammatory/atrophic lesions of the gastric mucosa, which may impair acid output. No systematic study has investigated the phenotype of the gastric mucosa coexisting with Barrett's oesophagus. This study was designed to identify the phenotype of gastric mucosa associated with Barrett's oesophagus.In this retrospective case control study, the phenotype of the gastric mucosa was histologically characterised in 53 consecutive patients with Barrett's oesophagus and in 53 (sex and age matched) non-ulcer dyspeptic controls. Both patients and control…

Post-transplant lymphoproliferative disorders after solid organ and hematopoietic stem cell transplantation.

2018

Post-transplant lymphoproliferative disorders (PTLD) are a rare complication after both solid organ (SOT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT). In this single center retrospective study, we compared clinical, biological, and histological features, and outcomes of PTLD after both types of transplant. We identified 82 PTLD (61 after SOT and 21 after allo-HSCT). The presence of B symptoms, Waldeyer ring, spleen, central nervous system, and liver involvement, and advanced Ann-Arbor stage were more frequent in allo-HSCT recipients. PTLD had an earlier onset in allo-HSCT than in SOT cohort (4 vs. 64 months, p  .0001). PTLD was EBV-positive in 100% of allo-HSCT, in co…
