BACKGROUNDEarly antiretroviral therapy initiation (ARTi) in HIV-1 restricts reservoir size and diversity while preserving immune function, potentially improving opportunities for immunotherapeutic cure strategies. For antibody-based cure approaches, the development of autologous neutralizing antibodies (anAbs) after acute/early ARTi is relevant but is poorly understood.METHODSWe characterized antibody responses in a cohort of 23 participants following ARTi in acute HIV (<60 days after acquisition) and early HIV (60-128 days after acquisition).

Broad-spectrum RAS inhibition has the potential to benefit roughly a quarter of human patients with cancer whose tumours are driven by RAS mutations. RMC-7977 is a highly selective inhibitor of the active GTP-bound forms of KRAS, HRAS and NRAS, with affinity for both mutant and wild-type variants. More than 90% of cases of human pancreatic ductal adenocarcinoma (PDAC) are driven by activating mutations in KRAS.

Article Synopsis
  • Scientists found that blocking RAS, a gene that can cause cancer when mutated, might help about 25% of cancer patients.
  • They tested a drug called RMC-7977 on various cancer models, especially pancreatic cancer, and saw it stopped tumors from growing without harming normal tissue.
  • The drug caused cancer cells to die off, but normal cells only slowed down a bit, showing it could be a good option for treating pancreatic cancer.

The UK National Diabetes Inpatient COVID Response Group was formed at the end of March 2020 to support the provision of diabetes inpatient care during the COVID pandemic. It was formed in response to two emerging needs. First to ensure that basic diabetes services are secured and maintained at a time when there was a call for re-deployment to support the need for general medical expertise across secondary care services.

Complex extremity wounds in Wounded Warriors can become contaminated with microbes, which may cause clinical outcomes resulting in amputation, morbidity, or even fatality. Local delivery of multiple or broad-spectrum antibiotics allows practicing clinicians treatment solutions that may inhibit biofilm formation. Propagation of vancomycin-resistant Staphylococcus aureus is also a growing concern.

Pneumatosis Intestinalis (PI) is an uncommon condition in which there is gas present within the wall of the gastrointestinal tract. PI is usually found in the large bowel, but can less commonly occur in the small bowel, and gas may be present in either the subserosal or submucosal layer of the intestine. Its unfamiliarity often means it is under-recognised and not considered as a differential diagnosis when assessing a patient with abdominal symptoms.

Continuously reducing excess blood glucose is a primary goal for the management of type 2 diabetes (T2D). Most patients with T2D require glucose-lowering medications to achieve and maintain adequate glycemic control; however, treatment failure may occur, limiting treatment options. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are an emerging therapeutic class that can be prescribed for patients instead of basal insulin after the failure of oral therapies.

Article Synopsis
  • The study aimed to evaluate a blended chitosan/polyethylene glycol paste as a potential local antibiotic delivery system for treating musculoskeletal wounds.
  • Three different chitosan/PEG paste compositions were tested for biocompatibility, degradation rates, and antibiotic release profiles using various lab techniques and animal models.
  • Results showed that one formulation was biocompatible while the others were not, and the paste demonstrated effective, sustained antibiotic release that prevented bacterial infections in treated cases.

Purpose: There is a need to broaden protective coverage of M protein-based vaccines against group A streptococci (GAS) because coverage of the current 30-valent M protein vaccine does not extend to all types. An additional GAS antigen and virulence factor that could potentially extend vaccine coverage is M-related protein (Mrp). Previous work indicated that there are three structurally related families of Mrp (MrpI, MrpII, and MrpIII) and peptides of all three elicited bactericidal antibodies against multiple types.

Background: Local drug delivery devices offer a promising method for delivering vancomycin and amikacin for musculoskeletal wounds. However, current local delivery devices such as beads and sponges do not necessarily allow for full coverage of a wound surface with eluted antibiotics and do not address the need for reducing the antibiotic diffusion distance to help prevent contamination by bacteria or other microorganisms. We blended chitosan/polyethylene glycol (PEG) pastes/sponges to increase biocompatibility and improve antibiotic coverage within the wound.

Background: A major obstacle to the development of broadly protective M protein-based group A streptococcal (GAS) vaccines is the variability within the N-terminal epitopes that evoke potent bactericidal antibodies. The concept of M type-specific protective immune responses has recently been challenged based on the observation that multivalent M protein vaccines elicited cross-reactive bactericidal antibodies against a number of non-vaccine M types of GAS. Additionally, a new "cluster-based" typing system of 175M proteins identified a limited number of clusters containing closely related M proteins.

Polymicrobial biofilm-associated implant infections present a challenging clinical problem. Through modifications of lyophilized chitosan sponges, degradable drug delivery devices for antibiotic solution have been fabricated for prevention and treatment of contaminated musculoskeletal wounds. Elution of amikacin, vancomycin, or a combination of both follows a burst release pattern with vancomycin released above minimum inhibitory concentration for Staphylococcus aureus for 72 h and amikacin released above inhibitory concentrations for Pseudomonas aeruginosa for 3 h.

Plasma high density lipoprotein-cholesterol (HDL-C) concentrations negatively correlate with atherosclerotic cardiovascular disease. HDL is thought to have several atheroprotective functions, which are likely distinct from the epidemiological inverse relationship between HDL-C levels and risk. Specifically, strategies that reduce HDL-C while promoting reverse cholesterol transport (RCT) may have therapeutic value.

Introduction: Although variations in the technique of awake craniotomy (AC) have been widely reported, a key member of this interdisciplinary procedure is the healthcare professional performing assessments of neurological function during resection. The expertise of the latter will depend on the neurological function to be tested and on available resources of the institution. This report details our initial experience of an AC service utilizing the expertise of a speech and language therapist (SLT) and an experienced neuro-physiotherapist (NP) to monitor patient function during glioma resection.
