Background: We report the largest European series of patients in whom both ventriculoperitoneal shunts (VPS) and percutaneous endoscopic gastrostomies (PEG) have been inserted with the aim of determining if this combination is safe or if there is an increased risk of VPS infection.
Patients And Methods: The paper and electronic records of 302 patients who had a ventriculoperitoneal (VP) shunt inserted in the regional Neurosciences unit at Salford Royal NHS Foundation Trust between 2002 and 2007 were reviewed.
Results: A total of 24 patients with VP shunts had 26 PEG inserted. Thirteen PEG were inserted in 11 patients with a pre-existing VP shunt. The median age was 58 years (21-77 Yrs) with seven male and 17 female patients. In total, five patients developed a shunt infection (20.8%) compared to the overall rate of VP shunt infection for Salford Royal NHS Foundation Trust of 7% (P = 0.017). The increase in number of VP shunt infections when the procedures were done more than 10 days apart (2/14) was not significant (P = 0.25).
Conclusion: In patients who need long-term enteral feeding following a VP shunt insertion it may be prudent to delay insertion of a PEG for at least 10 days to reduce VPS infection. In stable patients who have had a VP shunt inserted on previous hospital admissions PEG insertion need not be avoided because of concern regarding cerebrospinal fluid or shunt infection.

Intracortical microelectrodes (IMEs) are essential for neural signal acquisition in neuroscience and brain-machine interface (BMI) systems, aiding patients with neurological disorders, paralysis, and amputations. However, IMEs often fail to maintain robust signal quality over time, partly due to neuroinflammation caused by vascular damage during insertion. Platelet-inspired nanoparticles (PIN), which possess injury-targeting functions, mimic the adhesion and aggregation of active platelets through conjugated collagen-binding peptides (CBP), von Willebrand Factor-binding peptides (VBP), and fibrinogen-mimetic peptides (FMP).

Homogeneous antibody-drug conjugates (ADCs) exhibit significantly improved pharmacological properties compared to their heterogeneous counterparts. Site-specific conjugation of the payload to the IgG required for homogeneity can be achieved using enzymes. One example is microbial transglutaminase (MTGase), which can selectively perform transamidation on the Q295 residue of human Fc when N297 glycans are removed.

Background: Percutaneous Endoscopic Gastrostomy (PEG) tube insertion, a routine procedure for long-term enteral nutrition, serves as a crucial intervention for patients who are incapable of tolerating oral intake or meeting adequate nutritional requirements. PEG tube placement carries complications like bleeding and infection. Impact of PEG tubes on the 30-day and long-term mortality in HIV patients is unknown.

Home enteral nutrition (HEN) is a vital feeding practice for those who have chronic disorders that prevent them from eating normally. Although short-term feeding is predominantly done via nasogastric (NG) tubes and long-term feeding is done via percutaneous endoscopic gastrostomy (PEG) tube, we present a case that demonstrates that the long-term use of NG tubes may be possible. Our case involves an adult woman who has been fed via an NG tube for >3 years with no complications.

Polymeric carriers have long been recognized as some of the most effective and promising systems for nucleic acid delivery. In this study, we utilized an anionic di-block co-polymer, PEG-PLE, to enhance the performance of lipid-modified PEI (C14-PEI) nanoplexes for delivering Cas9 mRNA and sgRNA targeting KRAS G12S mutations in lung cancer cells. Our results demonstrated that PEG-PLE, when combined with C14-PEI at a weight-to-weight ratio of 0.
