Understanding the interplay between infections and severe acute malnutrition is critical in attaining good clinical outcomes when managing malnourished children. However, review studies describing the profile of the associated pathogens in the malnourished African paediatric population are sparse in the literature. We aimed to identify the spectrum of pathogens from studies reporting infections in severely malnourished African children, as well as the antibiotic resistance pattern and clinical outcomes. A systematic literature review of the PubMed database was conducted following PRISMA guidelines from January 2001 to June 2024. The search algorithm was ((marasmus) OR (kwashiorkor) OR (severe acute malnutrition) OR (protein energy malnutrition)) AND (Africa). For a more comprehensive retrieval, an additional search algorithm was deployed: ((HIV) OR (tuberculosis)) AND (severe acute malnutrition). We included 60 studies conducted between 2001 and 2024. Most of the studies were from East Africa (n = 45, 75%) and Southern Africa (n = 5, 8.3%). A total of 5845 pathogens were identified comprising 2007 viruses, 2275 bacteria, 1444 parasites, and 119 fungal pathogens. The predominant pathogens were HIV, , and malaria parasites accounting for 33.8%, 30%, and 24.2% of pathogens identified. Antibiotic susceptibility testing was documented in only three studies. Fatality rates were reported in 45 studies and ranged from 2% to 56% regardless of the category of pathogen. This review affirms the deleterious effect of infections in malnourished patients and suggests a gross underdiagnosis as studies were found from only 17 (31.5%) African countries. Moreover, data on fungal infections in severely malnourished African children were nearly absent despite this population being at risk. Thus, there is an urgent need to prioritize research investigating African children with severe acute malnutrition for fungal infections besides other pathogens and improve the availability of diagnostic tools and the optimized usage of antibiotics through the implementation of antimicrobial stewardship programmes.

Knee osteoarthritis contributes substantially to worldwide disability. Post-traumatic osteoarthritis (PTOA) develops secondary to joint injury, such as ligament rupture, and there is increasing evidence suggesting a key role for inflammation in the aetiology of PTOA and associated functional deficits. Colony stimulating factor 1 receptor (CSF1-R) has been implicated in the pathogenesis of musculoskeletal degeneration following anterior cruciate ligament (ACL) injury.

Background: In septic shock, the classic fluid resuscitation strategy can lead to a potentially harmful positive fluid balance. This multicenter, randomized, single-blind, parallel, controlled pilot study assessed the effectiveness of a restrictive fluid strategy aiming to limit daily volume.
Methods: Patients 18-85 years' old admitted to the ICU department of three French hospitals were eligible for inclusion if they had septic shock and were in the first 24 h of vasopressor infusion.

Background: Dementia is a progressive and terminal illness. Symptoms are present for people with dementia across all stages, leading to poor quality of life and considerable carer burden. In acute and community care services, no holistic, person-centred outcome tools are available for nurses and informal caregivers to measure symptoms and needs from the person`s with dementia point of view.

ABO-compatible Orthotopic Liver Transplantation (OLT) is the standard treatment for patients with acute liver failure (ALF) who meet the criteria for poor prognosis. Contraindications to liver transplantation may be related to the presence of severe medical or psychiatric comorbidities, or to an unstable clinical state incompatible with transplantation. Early mortality predictive scores and factors have been developed to identify futile transplantations that exacerbate organ shortage.

Acute liver failure (ALF) is defined as the loss of hepatic function in conjunction with hepatic encephalopathy and coagulopathy. There is histological evidence of profound hepatocyte damage. If it is not aggressively managed, ALF can be fatal within a few days.
