Article Abstract
Background: Nausea and vomiting are the common symptoms of early pregnancy. Without treatment, vomiting can complicate the pregnancy, so it must be reduced. Wide varieties of treatment have been used for nausea and vomiting in pregnancy. This study compared the effectiveness of vitamin B6 and dimenhydrinate for gestational nausea and vomiting.
Materials And Methods: One hundred and forty pregnant women with a gestational age of <16 weeks who had symptoms of nausea and vomiting were selected. They were randomly allocated into group A (n = 70) and group B (n = 70). The patients in group A received a vitamin B6 tablet, while the patients in group B received a dimenhydrinate tablet daily; the tablets were identical in appearance. The degree of nausea and vomiting was assessed by physical symptoms of Rhodes score.
Results: One hundred and thirty-five women returned to follow-up. Dimenhydrinate and vitamin B6 significantly reduced nausea and vomiting scores from 8.3 (7.4) to 2.8 (2.0) and from 8.6 (2.9) to 3.8 (2.3), respectively. The mean score change after treatment with dimenhydrinate was greater than with vitamin B6.
Conclusion: Both dimenhydrinate and vitamin B6 were effective in the treatment of nausea and vomiting in early pregnancy. Dimenhydrinate was more effective than vitamin B6.

In this double-blinded, randomized controlled trial, sixty patients undergoing elective uniportal video-assisted thoracoscopic surgery (VATS) lobectomy were randomly assigned to receive thoracoscopic intercostal nerve block (ICNB, n = 30) or ultrasound-guided erector spinae plane block (ESPB, n = 30). No block-related adverse events occurred. The ICNB group showed significantly lower resting and coughing visual analog scale scores, than the ESPB group, 4 (4.

Background: Dysregulation of polyamine synthesis has been observed in various cancer cell types. A novel approach to depriving cancer cells of polyamines involves the use of difluoromethylornithine (DFMO) to block polyamine biosynthesis in combination with AMXT 1501, a potent inhibitor of polyamine transport. Preclinical mouse tumor models showed that the combination of AMXT 1501 plus DFMO had strong antitumor activity, together with evidence of a stimulated immune response against tumors.

Exercise associated hyponatremia (EAH) is a medical condition that can occur during physical exertion. Initially, EAH was considered to be restricted to extreme endurance activities, such as ultramarathons and Ironman triathlons. However, it has been more recently recognized in a variety of sports, including team sports and in shorter-duration events.

Background: The choice of anaesthetic agents may influence specific aspects of postoperative recovery, such as haemodynamic stability, recovery times and the incidence of adverse events, in patients undergoing day-case laparoscopic cholecystectomy. Propofol is widely used in total intravenous anaesthesia (TIVA) for its favourable recovery profile, while etomidate, valued for its haemodynamic stability, is less commonly used due to concerns about adrenal suppression. This study aims to compare etomidate-based and propofol-based TIVA on postoperative quality of recovery in patients undergoing day-case laparoscopic cholecystectomy, hypothesising that etomidate is non-inferior to propofol.

Objective: Approximately 30% of the 700 000 US Gulf War Veterans (GWVs) report symptoms collectively termed Gulf War Illness (GWI), a multisymptom illness of uncertain pathophysiology. Prior studies in GWI focus on overlap with irritable bowel syndrome. This study examines the associations between upper gastrointestinal (UGI) symptoms, GWI and specialty GI care.
