Objectives: To determine the accuracy of emergency physicians (EPs) in diagnosing pneumoperitoneum with POCUS, and if the volume of pneumoperitoneum affects accuracy.
Methods: POCUS clips were obtained from patients undergoing intraperitoneal insufflation for an elective laparoscopic procedure. Video clips of the right upper quadrant and epigastric regions were obtained prior to insufflation and then after 500 ml, 1000 ml, and 1500 ml of insufflation. These clips were randomized and reviewed by three blinded ultrasound-trained EPs. For each clip they determined whether pneumoperitoneum was present or not.
Results: EPs chose correctly 71 % of the time. Overall sensitivity for detecting pneumoperitoneum was 66 % with a specificity of 85 %. Sensitivity for detecting small, medium, and large volumes of air was 53 %, 70 %, and 73 % respectively. The AUC for pneumoperitoneum overall was 0.753. The AUC for detecting small, medium, and large volumes of air was 0.688, 0.773, and 0.789 respectively. There was substantial agreement between EPs with a kappa of 0.658.
Conclusions: POCUS for pneumoperitoneum had moderate sensitivity, high specificity and moderate accuracy. The sensitivities increased with increasing volumes of air. This data suggests that POCUS has similar sensitivity to CXR for pneumoperitoneum.

Precision pesticide application mainly relies on canopy volume, resulting in varied application effectiveness across different density areas of orchard trees. This study examined pesticide application effectiveness based on the spray wind, canopy volume, and leaf area within the canopy, providing variable bases for precise regulation of spray wind and pesticide dosage. The study addresses the knowledge gap by utilizing laser detection and ranging (LiDAR) to measure the thickness and leaf area of orchard tree canopies.

Perioperative cardiac arrest (POCA) remains a major challenge in surgical settings, with low survival after cardiopulmonary resuscitation (CPR). This study aims to identify predictive factors for 24 h survival after CPR and cause of POCA. A retrospective, single-center study was conducted on patients aged ≥18 years who experienced POCA and received CPR in the operating room or within 2 h postoperatively at Chiang Mai University Hospital from 2010 to 2019.

The objective of this narrative review is to provide a systematic framework for veterinarians to investigate dairy calf health, focusing on critical control points and key performance indicators (KPIs) to address morbidity and mortality challenges in preweaned calves. Recommendations target prenatal maternal nutrition, heat stress abatement, and optimal calving management to minimize risks associated with perinatal mortality and preweaning morbidity. Further, comprehensive colostrum management is discussed to ensure excellent transfer of passive immunity, which includes prompt collection and feeding within two hours of birth at a volume of 8.

Vertical subsurface flow constructed wetlands (VSSF CWs) were employed to investigate the use of biochar that could be produced with local agricultural biomass through pyrolysis, recycled glass from local recycling companies and gel beads with decreased packing volume and shipping cost as substrate alternatives to sand. The materials were assessed in terms of granulometry, porosity, adsorption capacity and hydraulic conductivity and were used for the treatment of an upflow anaerobic sludge blanket (UASB) reactor, treating domestic wastewater, effluent. Granulometry was a major factor impacting TSS removal that ranged from 81% ± 10% to 97% ± 2%.
