This study explores the application of the Least Squares Method to analyze and model the kinematic parameters in monofin swimming, focusing on stroke rate, stroke length, and the amplitudes of joint displacements at the hip, knee, and ankle. The primary aim is to evaluate whether this method provides an objective and diagnostic tool for assessing monofin swimming techniques. Three elite monofin swimmers were evaluated under a progressive fatigue test. Results indicated that the stroke rate increases velocity by 0.95, 0.23, and 0.96 units (for the estimated models respectively). Optimized stroke length (0.01-0.12 units) also significantly correlates with velocity improvements. Joint amplitude reductions, particularly at the hip and ankle, enhanced propulsion by minimizing drag. This study highlights the Least Squares Method as a diagnostic tool for optimizing swimming techniques, with potential applications in performance training.

Neonicotinoids are systemic insecticides used in agriculture. In particular, imidacloprid (IM) and thiamethoxam (TM) have selective toxicity to insects, and they have been implicated in the steep decline of the global honeybee population, specifically in colony collapse disorder (CCD). Some scientific reports have shown that a significant amount of honey worldwide contains traces of neonicotinoids, at levels strong enough to cause damage to bees.

Background: Postoperative haemorrhage following palatine tonsillectomy occurs in 5-14% of cases. Since 2021, our department has used knot suturing with 3-0 Vicryl, and from 2023, continuous suturing with the V-Loc closure device to reduce suture time. While knot suturing is reported to reduce postoperative bleeding and pain, no studies have compared outcomes between different suture methods.

Background: Population-level preventive interventions are urgently needed and may be effective for psychosis due to social determinants. We tested three syndemic models along pathways from childhood adversity (CA) to psychotic spectrum disorder (PSD) and their implications for prevention.
Methods: Cross-sectional data from 7461 British men surveyed in 5 population subgroups.

Objective: This study aimed to observe changes in serum glucose levels following the administration of 50 mL of 50% dextrose solution (D50) in hypoglycemic patients. Specifically, we seek to determine the prevalence of rebound hyperglycemia episodes, the peak effect, and the duration of action of a single dose of 50 mL D50.
Method: This prospective observational study was conducted at four emergency departments (two tertiary care hospitals and two secondary care hospitals) in Oman over a three-year period, from May 1, 2019, to April 30, 2022.

Background: Liver transplantation (LT) is the standard treatment for liver failure secondary to alcohol-associated liver disease, but limited literature and best practices exist for post-LT treatment of alcohol use disorder (AUD). This study explores current AUD management practices and providers' perceived barriers to effective post-LT AUD management.
Methods: A 45-item survey on post-LT AUD treatment practices was distributed to members of the American Society of Transplant Surgeons, the Association of Consult/Liaison Psychiatry Transplant Special Interest Group, and both the American Society of Transplantation's Liver and Intestine Community of Practice and Psychosocial and Ethics Community of Practice discussion boards, between December 2021 and April 2022.
