Background: With the rise of artificial intelligence (AI) in medical education, tools like OpenAI's ChatGPT-4 and DALL·E 3 have potential applications in enhancing learning materials. This study aims to evaluate ChatGPT-4o's proficiency in recognizing bariatric surgical procedures from illustrations and assess DALL·E 3's effectiveness in generating accurate surgical illustrations.

Methods: Illustrations of six bariatric surgical procedures (One Anastomosis Gastric Bypass, Roux-en-Y Gastric Bypass, Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy, Sleeve Gastrectomy, Biliopancreatic Diversion, and Adjustable Gastric Banding) were sourced from the IFSO Atlas of Metabolic and Bariatric Surgery.

Background: While OAGB shows promise in the short to medium term, its long-term durability, weight trends, blood levels of metabolic factors and nutrients, and potential complications require further exploration through larger, longer-term studies. This study contributes to the growing body of evidence by reporting on the long-term outcomes of patients with severe obesity who underwent OAGB.

Methods And Patients: A retrospective study on prospectively collected data was conducted on a sample of 1917 patients who underwent OAGB between 2010 and 2019 and had a BMI ≥ 35 kg/m.

Article Synopsis
  • The study examines the variety of halophilic archaea in the geothermal waters of southern Tunisia, important for irrigation in arid regions.
  • Three types of samples—water, sediment, and halite-soil crust—were collected from two geothermal springs and analyzed using advanced DNA sequencing techniques.
  • Results indicated a shared presence of 20 out of 33 genera between the sources, with unique genera identified, suggesting these organisms can thrive in fluctuating conditions away from geothermal sites.

Thermal springs harbour microorganisms, often dominated by cyanobacteria, which form biofilms and microbial mats. These phototrophic organisms release organic exudates into their immediate surroundings, attracting heterotrophic bacteria that contribute to the diversity and functioning of these ecosystems. In this study, the microbial mats from a hydrothermal pool in the Ksar Ghilane oasis in the Grand Erg Oriental of the Desert Tunisia were collected to obtain cyanobacterial cultures formed by single cyanobacterial species.

  • Foreign body aspiration (FBA) is a serious and common emergency in children, which can lead to significant health risks.
  • A systematic review and meta-analysis were conducted to evaluate how effective chest CT scans are in diagnosing FBA in pediatric patients, assessing various studies published until May 2024.
  • The findings showed that chest CT scans have a very high sensitivity (99%) and specificity (97%) for identifying FBA, underscoring their diagnostic value despite some variability in study results.

The increasing salinity and alkalinity of soils pose a global challenge, particularly in arid regions such as Tunisia, where about 50% of lands are sensitive to soil salinization. Anthropogenic activities, including the use of treated wastewater (TWW) for irrigation, exacerbate these issues. Haloalkaliphilic bacteria, adapted to TWW conditions and exhibiting plant-growth promotion (PGP) and biocontrol traits, could offer solutions.

Background: Bariatric surgery patients may develop common bile duct stones, and the alterations in their anatomy present challenges in treating this condition. Methods such as laparoscopic bile duct exploration is impractical in many healthcare facilities, due to the absence of a choledochoscope. This study assesses the feasibility of laparoscopic exploration of the common bile duct using a disposable bronchoscope in these individuals.

Halophilic archaea are polyextremophiles with the ability to withstand fluctuations in salinity, high levels of ultraviolet radiation, and oxidative stress, allowing them to survive in a wide range of environments and making them an excellent model for astrobiological research. Natrinema altunense 4.1R is a halophilic archaeon isolated from the endorheic saline lake systems, Sebkhas, located in arid and semi-arid regions of Tunisia.

Bioremediation offers a viable alternative for the reduction of contaminants from the environment, particularly petroleum and its recalcitrant derivatives. In this study, the ability of a strain of Pseudomonas BUN14 to degrade crude oil, pristane and dioxin compounds, and to produce biosurfactants, was investigated. BUN14 is a halotolerant strain isolated from polluted sediment recovered from the refinery harbor on the Bizerte coast, north Tunisia and capable of producing surfactants.

Hexavalent chromium [Cr(VI)], widely generated by tannery activities, is considered among the most toxic substances and causes a serious damage for the environment and for human health. Interestingly, some microorganisms have a potential of bioremediation of chromium-contaminated wastewaters and soils through the reduction of Cr(VI) (soluble and harmful form) into Cr(III) (stable and non-toxic form). Here, we present the full genome sequence of a novel heavy-metal-resistant, plant growth-promoting bacterium (PGPB), TL13, which was isolated from a Tunisian leather industry.
