An uncommon liver abscess secondary to an ingested foreign body: A case report
No full textIntroduction: This article discusses a case study involving a unique occurrence of a hepatic abscess caused by the presence of an ingested foreign body. Hepatic abscesses, characterized by pus accumulation within liver tissue, often result from various infections, with some cases having unidentified origins. Case presentation: This study focuses on a 75-year-old man who presented at an emergency department with persistent pain in the right upper abdomen and fever for ten days. Diagnostic tests revealed a low-density, multiloculated mass in the liver and a hyperdense linear structure near the duodenum, indicating a hepatic abscess originating from duodenal perforation due to a foreign body that had migrated from ingestion. The patient underwent antibiotic treatment and a surgical procedure involving laparotomy to extract the foreign object and drain the abscess. Conclusion: this case study underscores the rare occurrence of hepatic abscesses caused by ingested foreign bodies. Swift and accurate diagnosis, along with appropriate treatment involving foreign body removal and abscess drainage, are pivotal for favorable patient outcomes. The choice of treatment strategy impacts hospital stay duration, and understanding potential complications from foreign body ingestion enhances patient management and care
The impact of curved-tip propeller geometry on hovering drone performance for air quality monitoring
No full textInternational audienceThe success or failure of a drone mission depend on several elements, including the drone’s mass and payload, the surrounding environment, the battery’s state, and the propulsion system’s performance. Several studies have been undertaken addressing the propeller performance of this final component, particularly for fixed-wing or quad copter drones with ducted propellers. However, the shape of propeller blades used on tiny civil drones has not drawn as much attention. In this research work, the performance characteristics of a 10 × 4.7-inch curved tip propeller were explored, with the Advanced Precision Composite drone propeller serving as a design reference. This study seeks an alternative to ducted propellers when mass or size limitations prevent their use. The Computational Fluid Dynamics model was confirmed by comparing simulation results to the experimental propeller data source established by the University of Illinois at Urbana-Champaign, starting with a standard type propeller and using thrust coefficient as the key performance indicator. Moreover, the data analysis for the bended tip propeller replicating the well-established model, revealed the benefits as well as the drawbacks of such propellers on the mission profile and the battery lifespan of a quad copter Unmanned Air Vehicle

Global 30-day morbidity and mortality of surgery for perforated peptic ulcer: GRACE study
No full textBackground: There is little international data on morbidity and mortality of surgery for perforated peptic ulcer (PPU). This study aimed to understand the global 30-day morbidity and mortality of patients undergoing surgery for PPU and to identify variables associated with these. Method: We performed an international study of adults (≥ 18 years) who underwent surgery for PPU from 1st January 2022 to 30th June 2022. Patients who were treated conservatively or had an underlying gastric cancer were excluded. Patients were divided into subgroups according to age (≤ 50 and > 50 years) and time from onset of symptoms to hospital presentation (≤ 24 and > 24 h). Univariate and Multivariate analyses were carried out to identify factors associated with higher 30-day morbidity and mortality. Results: 1874 patients from 159 centres across 52 countries were included. 78.3% (n = 1467) of the patients were males and the median (IQR) age was 49 years (25). Thirty-day morbidity and mortality were 48.5% (n = 910) and 9.3% (n = 174) respectively. Median (IQR) hospital stay was 7 (5) days. Open surgery was performed in 80% (n = 1505) of the cohort. Age > 50 years [(OR = 1.7, 95% CI 1.4–2), (OR = 4.7, 95% CI 3.1–7.6)], female gender [(OR = 1.8, 95% CI 1.4–2.3), (OR = 1.9, 95% CI 1.3–2.9)], shock on admission [(OR = 2.1, 95% CI 1.7–2.7), (OR = 4.8, 95% CI 3.2–7.1)], and acute kidney injury [(OR = 2.5, 95% CI 1.9–3.2), (OR = 3.9), 95% CI 2.7–5.6)] were associated with both 30-day morbidity and mortality. Delayed presentation was associated with 30-day morbidity [OR = 1.3, 95% CI 1.1–1.6], but not mortality. Conclusions: This study showed that surgery for PPU was associated with high 30-day morbidity and mortality rate. Age, female gender, and signs of shock at presentation were associated with both 30-day morbidity and mortality. Graphical abstract: (Figure presented.
Vida y obra de un médico morisco en el exilio: Muḥammad b. Aḥmad b. Abī l-‛Āṣ (ss. XVI-XVII)
No full textOne of the Spanish Muslim authors that could not be identified until now is Muḥammad b. Aḥmad b. Abī l-‛Āṣ al-Andalusī, to whom two short medical treatises are attributed. A study of the preserved manuscripts of both works, as well as the revision of some sources and recently published studies, will allow us to identify this author as the Granadan Morisco Muḥammad b. Abī l-‛Āṣī (or Muhhemed Bulhaç), a physician that in the first half of the 17th century left the Iberian Peninsula to reside in Istanbul, and afterwards in Cairo, where his trace is lost in the year 1637. In this article, we will expose all the available biographical data about this person, and we will make a brief analysis of his two treatises.Uno de los autores hispanomusulmanes que hasta la fecha no había podido ser identificado es Muḥammad b. Aḥmad b. Abī l-‛Āṣ al-Andalusī, a quien se atribuyen dos breves tratados sobre medicina. Un estudio de los manuscritos conservados de ambas obras, así como la revisión de algunas fuentes y estudios recientemente publicados, nos permiten identificar a este autor con el morisco granadino Muḥammad b. Abī l-‛Āṣī (o Muhhemed Bulhaç), médico que en la primera mitad del s. XVII abandonó la Península Ibérica para residir durante algunos años en Estambul y posteriormente en El Cairo, donde se pierde su pista en el año 1637. En el presente artículo, expondremos todos los datos biográficos disponibles de este personaje, y haremos un breve análisis de sus dos tratados

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
No full textAbstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
