BACKGROUND Results from studies conducted in the late 1980s and early 1990 s showed that gastrointestinal symptoms were common among the general population. Meanwhile, lifestyle habits have changed and important treatment options have been introduced. This might have influenced symptom prevalence. METHODS This study aimed to describe the current prevalence of upper and lower gastrointestinal ...

OBJECTIVE Determine whether absorbable or nonabsorbable mesh in repair of large hiatus hernias reduces the risk of recurrence, compared with suture repair. BACKGROUND Repair of large hiatus hernia is associated with radiological recurrence rates of up to 30%, and to improve outcomes mesh repair has been recommended. Previous trials have shown less short-term recurrence with mesh, but adverse ...

In the present study, we have investigated whether the peripheral cholinergic abnormalities that we have reported previously [Spence, Khan and Belch (2000) Am. J. Med. 108, 736-739] in patients with chronic fatigue syndrome (CFS) are also present in those with Gulf War syndrome (GWS) and agricultural workers exposed to organophosphate pesticides, where cholinesterase inhibition is specifically ...

Both dyspeptic and gastro-oesophageal reflux-like symptoms are frequent in the general population, but their degree of overlap is unknown. In severe functional dyspepsia (FD), symptoms are organized in factors associated with pathophysiological mechanisms. The aims of this study were: (i) to assess the prevalence of dyspeptic symptoms with and without overlapping reflux symptoms in the general ...

CONTEXT Although the high incidence of gastroesophageal reflux disease (GERD) in the population, there is much controversy in this topic, especially in the surgical treatment. The decision to use of a total or partial fundoplication in the treatment of GERD is still a challenge to many surgeons because the few evidence found in the literature.

California is the nation’s leading dairy state. Unfortunately, it is also home to two of the three worst air-sheds with respect to ozone (smog) pollution. California is also the second largest contributor of Greenhouse Gases (GHG; e.g., methane) in the nation. Current regulatory estimates suggest that dairy cows in central California emit smogforming, so-called volatile organic gases (VOCs) at ...

Rumen microorganisms and the host ruminant animal require many macro and micro minerals for normal growth and development. Among these minerals, sulfur is a necessary component of the amino acids cystine and methionine that are building blocks of proteins. In ruminants, many inorganic forms of sulfur (e.g. potassium sulfate and calcium sulfate) can be used because sulfate is reduced in the rume...
