Evaluation of optimizing Monteggia fracture-dislocation care: surgical innovations, radiological insights, and functional rehabilitation in adult patients

Background: Monteggia fractures, rare in adults, involve proximal ulna fracture and radial head dislocation. Managing these injuries poses challenges, fueling historical debates and driving advancements in internal fixation. Watson Jones' frustration highlights the ongoing pursuit of effective surgical approaches for optimal outcomes and functional limb restoration. his study aims to evaluate Monteggia fracture-dislocation treatment by analyzing radiological outcomes for structural insights and alignment post-surgery. Methods: This prospective observational study, conducted at Swapno general hospital, Mirpur-2, Dhaka, Bangladesh from 1st January 2021 to 31 January 2024, enrolled 30 patients with radiologically confirmed Monteggia fracture-dislocation. Surgical procedures involved creating an interval, anatomical reduction, and fixation, with regular follow-ups assessing outcomes, including range of motion, X-rays, and VAS scores, while statistical analysis utilized SPSS version 23. Results: The highest frequency percentage in the age distribution was observed among individuals aged 41-45, constituting 20% of the total sample, while the lowest frequencies were recorded in the 31-35 and >51 age groups, each representing 10% of the sample. Physical assault emerged as the leading cause of injury, accounting for 40% of cases, followed by road traffic accidents at 36.66% and falls at 23.33%. In terms of final outcomes, the majority of patients (43.33%) achieved a good outcome, while the lowest percentage (10%) resulted in poor outcomes.  Conclusions: In conclusion, addressing Monteggia fracture-dislocation in adults requires navigating inherent complexities. Modern internal fixation methods prove impactful, emphasizing the need for precise classification and stable anatomical reduction

Antioxidant properties of BJRI vegetable mesta-1 (Hibiscus sabdariffa L.)

Roselle or Mesta (Hibiscus sabdariffa) is one of the plants whose plant parts are used to prepare juices. The Roselle calyx is considered as a good source of antioxidants. But the antioxidant properties of BJRI (Bangladesh Jute Research Institute) released Roselle vegetable variety, BJRI vegetable mesta-1, is not quantified yet. With the objective of making this vegetable more popular among the consumers, an experiment was conducted at the Jute Agriculture Experimental Station, Bangladesh Jute Research Institute, Jagir, Manikganj to find out the antioxidant properties of BJRI vegetable mesta-1. Total four antioxidant components eg., total phenol content, total flavonoid content, proanthocyanidin content, anthocyanin content and three antioxidant activities eg., DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging, (FRAP) ferric ion reducing antioxidant power, H2O2 (hydrogen peroxide), radical scavenging were measured from the calyx sample of BJRI vegetable mesta-1. Among the four antioxidant components, total flavonoid contents (959.53 mg 100 g–1) posses the highest position and anothocyanine contents (0.17 mg 100 g–1) were in the lowest position. FRAP activities were highest among the antioxidant activities of the calyx of our studied vegetable mesta. Our findings represented the quantity of antioxidant contents of the calyx of BJRI vegetable mesta-1 which justify its uses as natural antioxidants. Thus, Roselle calyx may act as an alternative source of antioxidant rich natural herbal tea

3D Ionospheric Imaging for Space Weather Monitoring at Low-Latitudes

Three-dimensional (3D) ionospheric imaging at Low-Latitudes is challenging due to the high ionospheric variability and dynamics in the region. The region is characterized by the presence of the Equatorial Ionization Anomaly (EIA), plasma bubbles, layered structures, and strong vertical drifts upwards during the evening pre-reversal enhancement. Aiming to better understand the ionosphere at low latitudes, this study shows the latest developments conducted by the authors to map the region with 3D inversion algorithms based on Global Navigation Satellite Systems (GNSS), ionosondes, GNSS radio-occultation, and empirical models, such as the International Reference Ionosphere (IRI). We address the capabilities of the developed 3D imaging methods to disclose the main morphologies and dynamics of the ionospheric electron density in the region. Limitations are also discussed since data assimilation schemes are still ill-conditioned for a complete 3D reconstruction. Based on the experiments conducted by the authors, the main conclusions have outlined that better 3D representation of the ionosphere in the region of particular interest requires three main improvements: 1) denser GNSS networks on ground and space; 2) better representation by empirical models to be used as background to the inversion technique, mainly to better represent the plasmasphere, topside ionosphere, and during the pre-reversal enhancements; and 3) dedicated signals for navigation transmitted by Low Earth Orbit (LEO) satellites
