Background: Agricultural handle equipment is present on all production areas' farms. They are handy and portable; however, excessive use can lead to acute traumas or accidental injuries. Repetitive movements, awkward postures, and hand-arm vibrations predispose them to pain and work-related musculoskeletal disorders. The purpose of this study was to observe the interaction of handle equipment in terms of electromyographic activity and analyze the postural work-related alterations. Materials and methods: Twenty male agricultural operators, mean age 24±1.54 years, underwent the electromyographic analysis testing their muscular activities with a brushcutter, electric saw, and hedge trimmer in four different test conditions. Results: The brushcutter proved to be the agricultural handle equipment with the higher mean frequency (3.37±0.38 Hz) and root mean square (5.25±1.24 ms^-2). Furthermore, the digital postural analysis showed a general asymmetry of the main arm and the respective side of the trunk. The head resulted right inclined in the anterior frontal plane by 5.7°±1.2°; the right scapula lower than the left in the posterior frontal plane (8.5°±1.8°), and a working trunk inclination of 34.15°±5.7°. Conclusions: Vibrations of handle equipment and awkward working postures represent a risk for agricultural operators. Preventive measures are required to avoid young operators from experiencing musculoskeletal disorders all lifelong.

Purpose: This article was to collect data on the safety of coronavirus disease 2019 (COVID-19) vaccines in children with underlying medical conditions. Methods: We constructed a prospective cohort of children and adolescents aged 5 to 19 years who had received at least one dose of COVID-19 vaccine. Patients diagnosed with and treated for chronic kidney disease, autoimmune disease, or other chronic conditions at the Seoul National University Children's Hospital were recruited from June to December 2022. A mobile survey questionnaire was sent to their guardians. The presence of adverse events on the day (day 0), 3 weeks (day 21), and 6 months (day 180) after the 1st dose of COVID-19 vaccine was recorded by the guardians. Results: A total of 73 children participated. The median age was 14 years, and 64.4% of the patients were male. On the day of immunization, 65.8% of the patients reported at least one adverse event. Pain at the injection site, fatigue, headache, arthralgia, and myalgia were the most common symptoms. The prevalence of adverse events decreased over time (65.8% on day 0, 27.4% between days 0 and 21, and 24.6% between days 21 and 180). Severe acute respiratory syndrome coronavirus 2 infection after the 1st dose occurred in 17 patients (23.3%) and one of the patients (5.88%) was hospitalized due to infection. Conclusions: Adverse events after COVID-19 vaccination were generally mild in children and adolescents with underlying medical conditions. Our findings provide evidence for the safety of COVID-19 vaccination in the vulnerable pediatric population.

Cough is a common symptom of several respiratory diseases. However, frequent coughing from acute to chronic often causes great pain to patients. It may turn into cough variant asthma, which seriously affects people's quality of life. For cough treatment, it is dominated by over-the-counter antitussive drugs, such as asmeton, but most currently available antitussive drugs have serious side effects. Thus, there is a great need for the development of new drugs with potent cough suppressant. BALB/c mice were used to construct mice model with cough to investigate the pharmacological effects of pectolinarigenin (PEC). Hematoxylin-eosin and Masson staining were used to assess lung injury and airway remodeling, and ELISA was used to assess the level of inflammatory factor release. In addition, inflammatory cell counts were measured to assess airway inflammation. Airway hyperresponsiveness assay was used to assess respiratory resistance in mice. Finally, we used Western blotting to explore the potential mechanisms of PEC. We found that PEC could alleviate lung tissue injury and reduce the release of inflammatory factors, inhibit of cough frequency and airway wall collagen deposition in mice model with cough. Meanwhile, PEC inhibited the Ras/ERK/c-Fos pathway to exhibit antitussive effect. Therefore, PEC may be a potential drug for cough suppression.

Objective: This study is a single-group pre-post experimental study to determine the effects of simulation-based practice education on nursing students' self-efficacy, performance confidence, and educational satisfaction. Design: Single-group pre-post experimental studies Methods: This study was conducted from September 1, 2023 to November 30, 2023 for nursing undergraduate students in a simulation based practical education program. The subjects were provided with learning materials about an acute myocardial infarction case with chest pain for preliminary learning. After that, they were divided into teams of 6 people and asked to do self-study for 2 hours per team, twice a week, before conducting simulation practice. For the simulation based practical education, the participants were divided into 9 teams of 6 people each, and each team had 10 minutes for orientation, 15 minutes for scenario operation, and 50 minutes for debriefing. Results: After the simulation based practical education, self-efficacy increased statistically significantly from a mean of 3.51 before training to a mean of 3.80 after training (t=-2.12, p=0.038). However, there was no significant difference in performance confidence. There was a significant positive correlation between self-efficacy and performance confidence (r=0.62, p<0.001) and training satisfaction (r=0.67, p<0.001) after the simulation based practical education. Self-confidence was also significantly correlated with educational satisfaction (r=0.76, p<0.001). Conclusions: The results of this study showed that utilizing simulation-based practical education can increase nursing students' self-efficacy, which positively affects their performance confidence and educational satisfaction. Therefore, simulation-based practical education is an effective nursing education method that can improve nursing students' practical skills.

Hepatic compartment syndrome (HCS) is a rare but life-threatening entity that consists of a decreased portal flow due to intraparenchymal hypertension secondary to subcapsular liver hematoma. Lethal liver failure can be observed. We report three cases, and review the literature. A 54-year-old male was admitted for extensive hepatic subcapsular hematoma after blunt abdominal trauma. Initially, he underwent embolization of the hepatic artery's right branch, after which he presented clinical deterioration, major cytolysis (310 times the upper limit of normal [ULN]), and liver failure with a prothrombin time (PT) at 31.0%. A 56-year-old male underwent liver transplantation for acute alcoholic hepatitis. On postoperative day 2, he presented a hemorrhagic shock associated with deterioration of liver function (cytolysis 21 ULN, PT 39.0%) due to extensive hepatic subcapsular hematoma. A 59-year-old male presented a hepatic subcapsular hematoma five days after a cholecystectomy, revealed by abdominal pain with liver dysfunction (cytolysis 10 ULN, PT 63.0%). All patients ultimately underwent urgent surgery for liver capsule excision, hematoma evacuation, and liver packing, if needed. The international literature was screened for this entity. These three patients' outcomes were favorable, and all were alive at postoperative day 90. The literature review found 15 reported cases. HCS can occur after any direct or indirect liver trauma. Surgical decompression is the main treatment, and there is probably no place for arterial embolization, which may increase the risk of liver necrosis. A 13.3% mortality rate is reported. HCS is a rare complication of subcapsular liver hematoma that compresses the liver parenchyma, and leads to liver failure. Urgent surgical decompression is needed.

Objectives : This study examined the historical evolution of the GV26 acupuncture point, focusing on its location, therapeutic indications, and anatomical relevance to the philtrum region. Methods : We reviewed 18 historical acupuncture texts, analyzing the descriptions of GV26's location and associated indications. Results : The location of GV26 has varied over time. Early texts like the A-B Classics of Acupuncture and Moxibustion described it at the center of the philtrum groove, while some 16th-century texts shifted it closer to the nasal cavity. However, many sources continued to emphasize the central philtrum groove as the correct location. GV26 was historically indicated for conditions such as cold-type headache, epilepsy, edema, nasal and eye symptoms, respiratory issues, post-stroke symptoms, jaundice, pestilence, mouth-related symptoms, and low back pain. Epilepsy, edema, and post-stroke facial symptoms were consistently cited across texts, while other indications varied. Cadaveric studies show that the superficial orbicularis oris muscle divides into the upper nasalis and lower labialis portions. Needling the upper third of the philtrum stimulates the thinner, closer-to-maxilla upper nasalis portion, potentially providing stronger stimulation, while needling the center targets the lower labialis portion. Conclusions : Historical variations in GV26's location reflect an evolving understanding of its anatomical and therapeutic significance. The upper third of the philtrum groove may be more effective for acute conditions requiring strong stimulation, whereas the central groove may better address a broader range of conditions. These findings highlight the importance of historical and anatomical context in optimizing GV26's clinical use.
