The objective of the study was to compare the performance of five types of stomach tubes for rumen fluid sampling. Rumen fluid was sampled in rumen fistulated cows assigned to a 5×5 Latin square study design. The pH values of samples taken by stomach tubes and via fistulas were measured; the results were compared with indwelling sensor measurements. The practicability of the stomach tubes for regular use was tested in the field. Rumen fluid samples were obtained rapidly. Volumes for transfaunation could be obtained. The pH-values of samples taken with the four out of the five tubes (Dirksen, Geishauser, tube 4 and a simple water hose used with a gag) did not show significant differences to samples taken via rumen fistulas. Mean differences ranged between -0.02 and +0.09. Samples taken with tube 4 and the water hose showed also no significant differences to pH-sensor measurements. This study demonstrates that stomach tubes are suitable for rumen fluid sampling. Tube 4 seems to be the best probe for work in the field. It was well tolerated by the animals, saliva contamination is negligible. We, therefore, conclude that the evaluation of rumen acid base status in the field is possible.

Introduction: Percutaneous endoscopic gastrostomy (PEG) placement is a common procedure for patients requiring non-oral feeding. One rare complication of PEG placement is the formation of a gastrocolocutaneous fistula that develops when the bowel is caught between the stomach and abdominal wall during placement. This report explores an elderly patient's gastrocolocutaneous fistula development months post-PEG placement who presented with malodorous leakage from the gastrostomy tube to the emergency department (ED).

Efficacy and Safety of Orogastric vs. Nasogastric Tube Feeding in Preterm Infants: A Systematic Review and Meta-Analysis.

Children (Basel)

Department of Neonatology, Children's Hospital, School of Medicine, Zhejiang University, National Clinical Research Center for Child Health and Disease, Hangzhou 310052, China.

Background: Enteral nutrition can be delivered to the stomach using nasogastric or orogastric tubes, with each route having advantages and disadvantages. This meta-analysis aimed to compare the effects of these methods on growth, development, and the incidence of adverse outcomes.

Methods: This analysis included studies that enrolled preterm infants who received nasogastric or orogastric tube feeding.

Purpose: The study aimed to evaluate the efficacy of the Biologically Transparent Illumination (BTI) device for confirming the correct placement of nasogastric (NG) tubes in children, as an alternative to X-ray, which exposes patients to radiation.

Methods: In this prospective observational study, 106 pediatric patients (ages 0-16) undergoing NG-tube insertion after general anesthesia were evaluated. The BTI catheter was used to emit bio-permeable red light from the NG tube, which was then visually confirmed in the cervical, thoracic, and epigastric regions.

Shenzhen MSU-BIT University, International University, Park Road, 1, Shenzhen, Longgang District, Guangdong Province, 518172, PR China.

Urine analysis is an attractive approach for non-invasive cancer diagnostics. In this study, a procedure for the determination of volatile organic compounds (VOCs) in human urine (acetone, acetonitrile, dimethylsulfide, dimethyl disulfide, dimethyl trisulfide, hexane, benzene, toluene, 2-butanone, 2-pentanone, pentanal) has been described including sample preparation using preconcentration of analytes in sorbent tubes followed by gas chromatography with mass spectrometry (GC-MS). Fractional factorial design and constrained surfaces design were used to optimize preconcentration of VOCs in sorbent tubes.

Introduction And Importance: Laparoscopic sleeve gastrectomy is a prevalent bariatric surgery for managing morbid obesity. Despite its efficacy, complications can arise, particularly from intraoperative devices such as esophageal thermometers and orogastric tubes. These devices, if misplaced or inadequately monitored, can migrate and become entrapped or sectioned during surgery, leading to significant morbidity.
