Objective: A Colorectal Development Unit (CDU) was established to treat patients with end stage faecal incontinence with the electrically stimulated gracilis neoanal sphincter (ESGN). The aim of this study was to investigate the impact of the CDU on functional outcome and complications.
Methods: From March 1997 to March 2003, 53 patients underwent ESGN formation. Results were compared with 65 patients undergoing ESGN surgery prior to the establishment of the unit (pre-CDU) between 1988 and 1997, which were similar with regard to age, sex, aetiology and follow-up.
Results: Thirty-three (70%) CDU patients had a good functional outcome defined as continence to solid and liquid stool, a significant improvement when compared to the pre-CDU group, successful in 29 (45%) (P = 0.01). Episodes of technical complications leading to stimulator replacement were significantly reduced, from 25 to 3 over time (P < 0.001). Severe septic episodes were significantly reduced from 21 to four (P = 0.003) but there was no significant change in the incidence of postoperative evacuatory dysfunction.
Conclusion: Since setting up a CDU, a successful outcome has been achieved in 33 (70%) of 47 patients undergoing ESGN surgery, which represents a significant improvement over time. This is probably related to improved patient assessment and selection, more reliable equipment and increased operative and peri-operative experience that come with a multidisciplinary team approach.

Background: Understanding the interference patterns of respiratory viruses could be important for shedding light on potential strategies to combat these human infectious agents.
Objective: To investigate the possible interactions between adenovirus type 2 (AdV2), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A/H1N1 pandemic (H1N1pdm09) using the A549 cell line.
Methods: Single infections, co-infections, and superinfections (at 3 and 24 h after the first virus infection) were performed by varying the multiplicity of infection (MOI).
Metformin in Antiviral Therapy: Evidence and Perspectives.

Metformin, a widely used antidiabetic medication, has emerged as a promising broad-spectrum antiviral agent due to its ability to modulate cellular pathways essential for viral replication. By activating AMPK, metformin depletes cellular energy reserves that viruses rely on, effectively limiting the replication of pathogens such as influenza, HIV, SARS-CoV-2, HBV, and HCV. Its role in inhibiting the mTOR pathway, crucial for viral protein synthesis and reactivation, is particularly significant in managing infections caused by HIV, CMV, and EBV.

Access to safe water and food is a critical issue in sub-Saharan Africa, where microbial contamination poses significant health risks. Conventional water treatment and food preservation methods have limitations in addressing water safety, particularly for antibiotic-resistant bacteria and other pathogenic microorganisms. This review explores the potential application of bacteriophages as an innovative solution for water treatment and food safety in the region.

Cytomegalovirus (CMV) infection in solid organ transplant (SOT) and hematopoietic cell transplant (HCT) recipients may increase the risk of rejection or allograft dysfunction, other infection(s), and morbidity and mortality. Treatment can be challenging due to medication-associated toxicities. Maribavir (MBV) is a promising option for the treatment of resistant or refractory (R/R) CMV infection in lieu of foscarnet (FOS), which has long been the recommended therapy for (val)ganciclovir-resistant infection.

Wolbachia-based mosquito control strategies have gained significant attention as a sustainable approach to reduce the transmission of vector-borne diseases such as dengue, Zika, and chikungunya. These endosymbiotic bacteria can limit the ability of mosquitoes to transmit pathogens, offering a promising alternative to traditional chemical-based interventions. With the growing impact of climate change on mosquito population dynamics and disease transmission, Wolbachia interventions represent an adaptable and resilient strategy for mitigating the public health burden of vector-borne diseases.
