Synchronous Gallstone Ileus and Bouveret's Syndrome: A Report of Two Rare Concurrent Complications of Gallstone Disease.

Cholecystoenteric fistulas occur as a result of a chronic inflammatory insult involving the gallbladder and the erosion of both its wall and a bowel segment. When the fistula develops, it creates a pathway for gallstones to migrate and cause an intestinal obstruction, known as gallstone ileus. When it obstructs the gastric outlet, a proximal variant of gallstone ileus occurs, known as Bouveret's syndrome.

Characterisation of institutionalised Portuguese older adult fallers: is there a place for pharmacist intervention? A preliminary study.

Background: Falls are a major public health issue, given their prevalence and social impact. Older adults living in long-term care facilities (LTCF) are at greater risk of injury resulting from a fall due to multiple factors, such as nutritional, functional/cognitive impairment, postural instability, polypharmacy, and the presence of potentially inappropriate medications (PIMs). Medication management in LTCF is complex and often sub-optimal and might be crucial for falls.

In a cyberphysical production system, the connectivity between the physical entities of a production system with the digital component that controls and monitors that system takes fundamental importance. This connectivity has been increasing from the transducers' side, through gathering new functionalities and operating increasingly independently, taking the role of smart transducers, and from the applications' side, by being developed in a distributed and decentralized paradigm. This work presents a plug-and-play solution capable of integrating smart transducers compliant with the IEEE 1451 standard in industrial applications based on the IEC 61499 standard.

Fluoride Exposure and Salivary Glands: How Is Glandular Morphology Susceptible to Long-Term Exposure? A Preclinical Study.

Despite a strong body of evidence attesting to the effectiveness of fluoride (F) in preventing and controlling caries, some studies have sought to investigate the influence of F exposure on the salivary glands, organs that are essential for the maintenance of cavity homeostasis through salivary production, finding that exposure to F can cause biochemical and proteomic changes. Thus, this study aimed to investigate the morphological effects of prolonged exposure to F on the salivary glands of mice, at concentrations that would correspond to optimally fluoridated water (suitable for human consumption) and to fluorosis-endemic regions. Twenty-four male mice () were divided into three groups, according to F levels in the drinking water: 0 (control), 10, or 50 mg F/L, with an exposure period of 60 days.
