Fungal Guttation, a Source of Bioactive Compounds, and Its Ecological Role-A Review.

Guttation is a common phenomenon in the fungal kingdom. Its occurrence and intensity depend largely on culture conditions, such as growth medium composition or incubation temperature. As filamentous fungi are a rich source of compounds, possessing various biological activities, guttation exudates could also contain bioactive substances.

Strengths and Challenges of Various Models of Geriatric Consultation for Older Adults Living With Human Immunodeficiency Virus.

As care of persons living with human immunodeficiency virus (HIV; PWH) has transitioned from management of opportunistic infections to management of conditions associated with older age, new models of geriatric consultation are needed. The authors, who represent 9 clinics across North America and the United Kingdom, provided their insights on models of geriatric consultation for older PWH. Three models of geriatric consultation are delineated: outpatient referral/consultation, combined HIV/geriatric multidisciplinary clinic, and dually trained providers within 1 clinical setting.

Metabolic disorders and cardiovascular risk in treatment-naive HIV-infected patients of sub-saharan origin starting antiretrovirals: impact of westernized lifestyle.

In a cohort of HIV-infected patients of sub-Saharan origin we describe the incidence of metabolic syndrome, insulin resistance, and lipodystrophy after 3 years of combined antiretroviral therapy, and model the 10-year risk of cardiovascular diseases, while taking into account environmental factors. This is a multinational, prospective cohort study conducted in HIV outpatient clinics from four tertiary care centers set in France and Côte d'Ivoire. The participants were HIV-infected, treatment-naive patients eligible to start antiretroviral treatment and were of sub-Saharan African origin.

One-stage exchange arthroplasty for chronic periprosthetic hip infection: results of a large prospective cohort study.

Background: Exchange arthroplasty of one or two stages is required for the treatment of chronic periprosthetic joint infections. Two-stage exchange is costly and has high morbidity with limited patient mobility between procedures. One-stage exchange has been promoted by several European teams as the preferred alternative.

A functional magnetic resonance imaging investigation of uncertainty in adolescents with anxiety disorders.

Background: Pediatric anxiety disorders, although highly prevalent, are understudied with little known about their pathophysiology. Intolerance of uncertainty (IU) is a trait associated with worry, a key characteristic of these disorders. Neural responses to uncertainty in healthy subjects involve the same frontal-limbic circuits that are hyper-responsive in pediatric anxiety.
