In a retrospective study conducted in three hospitals in Paris, generic antiretroviral accounted for 30.2% of all prescriptions. Tenofovir disoproxil/emtricitabine (TDF/FTC) was the most prescribed generic ART (82.

Revealing the hidden interplay: The unexplored relationship between fungi and viruses beyond HIV, SARS-CoV-2, and influenza.

The complex interaction between viruses and fungi has profound implications, especially given the significant impact of these microorganisms on human health. While well-known examples such as HIV, influenza, and SARS-CoV-2 are recognized as risk factors for invasive fungal diseases, the relationship between viruses and fungi remains largely underexplored outside of these cases. Fungi and viruses can engage in symbiotic or synergistic interactions.

Allergic fungal rhinosinusitis and eosinophilic mucin chronic rhinosinusitis: Differential diagnostic criteria. A two-center comparative study following STROBE methodology.

Objectives: Allergic fungal rhinosinusitis (AFRS) and eosinophilic mucin chronic rhinosinusitis (EMRS) are two forms of chronic sinusitis distinguished by the presence (AFRS) or absence (EMRS) of fungal elements in sinus mucin. Detection of the fungal elements, however, is complex and it is difficult to say whether EMRS is in fact an entity distinct from AFRS. The aim of the present study, based on a retrospective series of AFRS and EMRS, was to identify the specific clinical and radiological elements distinguishing between the two.

[Prevalence, consequences of female genital mutilation among asylum seekers in Ile-de-France and socio-demographic characteristics].

Introduction: Female Genital Mutilation (FGM) is an intervention on the female genital organs for non-medical reasons. In France, asylum is possible for girls at risk of FGM in their country of origin. The procedure includes a forensic examination of the child.

The FilmArray Blood Culture Identification 2 panel (BCID2; bioMérieux) is a fully automated PCR-based assay for identifying bacteria, fungi, and bacterial resistance markers in positive blood cultures (BC) in about 1 h. In this multicenter study, we evaluated the performance of the BCID2 panel for pathogen detection in positive BC. Conventional culture and BCID2 were performed in parallel at four tertiary-care hospitals.

A systematic review and meta-analysis of delayed help-seeking, delayed diagnosis and duration of untreated illness in bipolar disorders.

Objectives: To examine the time delay between the age at onset of symptoms or episodes of bipolar disorders (BD) and the age at diagnosis of and/or receipt of clinical practice guideline recommended interventions for BD.

Methods: Systematic search of five databases to identify publications from January 2000 to July 2022 that reported one or more of the following reliable and valid estimates of latency: delay in help seeking (DHS), delay in diagnosis (DD) and duration of untreated BD (DUB). Eligible studies were included in random effects meta-analyses and multivariate meta-regression was used to assess factors associated with each latency construct.

Klebsiella pneumoniae Carbapenemase Variants Resistant to Ceftazidime-Avibactam: an Evolutionary Overview.

First variants of the Klebsiella pneumoniae carbapenemase (KPC), KPC-2 and KPC-3, have encountered a worldwide success, particularly in K. pneumoniae isolates. These beta-lactamases conferred resistance to most beta-lactams including carbapenems but remained susceptible to new beta-lactam/beta-lactamase inhibitors, such as ceftazidime-avibactam.

Prodromal characteristics of dementia with Lewy bodies: baseline results of the MEMENTO memory clinics nationwide cohort.

Background: Isolated subjective cognitive impairment (SCI) and mild cognitive impairment (MCI) are the prodromal phases of dementia with Lewy bodies (DLB). MEMENTO is a nationwide study of patients with SCI and MCI with clinic, neuropsychology, biology, and brain imaging data. We aimed to compare SCI and MCI patients with symptoms of prodromal DLB to others in this study at baseline.

The current state of clinical mycology in Africa: a European Confederation of Medical Mycology and International Society for Human and Animal Mycology survey.

Africa, although not unique in this context, is a favourable environment for fungal infections, given the high burden of risk factors. An online survey was developed asking about laboratory infrastructure and antifungal drug availability. We received 40 responses (24·4% response rate) of 164 researchers contacted from 21 African countries.

Local and Global Protein Interactions Contribute to Residue Entrenchment in Beta-Lactamase TEM-1.

Due to their rapid evolution and their impact on healthcare, beta-lactamases, protein degrading beta-lactam antibiotics, are used as generic models of protein evolution. Therefore, we investigated the mutation effects in two distant beta-lactamases, TEM-1 and CTX-M-15. Interestingly, we found a site with a complex pattern of genetic interactions.

Inoculum effect of Enterobacterales co-expressing OXA-48 and CTX-M on the susceptibility to ceftazidime/avibactam and meropenem.

Background: The treatment of infections caused by OXA-48/CTX-M-coproducing Enterobacterales may be based on new beta-lactam/beta-lactamase inhibitors, such as ceftazidime/avibactam (CZA), or on high dose of meropenem (MER). However, bacterial density at the infection site may vary widely, and the inoculum effect of such antimicrobial strategies has never been specifically investigated. To determine if CZA or MER susceptibilities are impacted by high inocula of Enterobacterales co-expressing both enzymes: OXA-48 like and CTX-M.

A systematic review and meta-analysis of sleep and circadian rhythms disturbances in individuals at high-risk of developing or with early onset of bipolar disorders.

Sleep and circadian rhythms disturbances (SCRD) in young people at high risk or with early onset of bipolar disorders (BD) are poorly understood. We systematically searched for studies of self, observer or objective estimates of SCRD in asymptomatic or symptomatic offspring of parents with BD (OSBD), individuals with presentations meeting recognised BD-at-risk criteria (BAR) and youth with recent onset of full-threshold BD (FT-BD). Of 76 studies eligible for systematic review, 35 (46%) were included in random effects meta-analyses.

Coronavirus Disease 2019-Associated Mucormycosis in France: A Rare but Deadly Complication.

We studied COVID-19 associated mucormycosis based on 17 cases reported nationwide and assessed the differences with India. They differed by frequencies of diabetes mellitus (47% in France versus up to 95% in India), hematological malignancies (35% versus 1%), anatomical sites (12% versus >80% rhino-orbito-cerebral) and prognosis (88% mortality versus <50%).

Retrospective study of toxoplasmosis prevalence in pregnant women in Benin and its relation with malaria.

Background: Globally distributed with variable prevalence depending on geography, toxoplasmosis is a zoonosis caused by an obligate intracellular protozoan parasite, Toxoplasma gondii. This disease is usually benign but poses a risk for immunocompromised people and for newborns of mothers with a primary infection during pregnancy because of the risk of congenital toxoplasmosis (CT). CT can cause severe damage to fetuses-newborns.
