Weight gain in antiretroviral therapy-naive HIV-1-infected patients starting a regimen including an integrase strand transfer inhibitor or darunavir/ritonavir.

Background: Weight gain after initiation of combination antiretroviral therapy (cART) is a possible side effect of all antiretroviral regimens, but it seems to be more evident in association with integrase strand transfer inhibitors (INSTIs). So, we aimed to evaluate weight change associated with an initial cART including one INSTI or darunavir-ritonavir (DRV/r).

Methods: A retrospective, observational, cohort study of antiretroviral therapy-naive adult HIV-positive patients starting an initial cART including raltegravir (RAL), dolutegravir (DTG), elvitegravir-cobicistat (EVG), or DRV/r.

Clinical pharmacology of monoclonal antibodies targeting anti-PD-1 axis in urothelial cancers.

Chemotherapy is the reference treatment for patients with advanced urothelial carcinoma, both in the neo-adjuvant and adjuvant settings; however, the overall outcome remains poor in this patient population. In the last few years, the addition of immune checkpoint inhibitors into the therapeutic armamentarium has changed the therapeutic landscape of several tumor types, including urothelial carcinoma. Many different molecules have been introduced on the market and several questions about immunotherapies are currently open and deserve a critical analysis.

Rectal Microbiota Associated With and Infections in Men Having Sex With Other Men.

(CT) and (NG) represent the most common agents of sexually transmitted rectal infections among men having sex with other men (MSM). In this study, we assessed the bacterial composition of the rectal microbiota associated with CT and/or NG infections in a cohort of men reporting unsafe rectal intercourse. A total of 125 rectal swabs were collected and four groups were compared: non-infected subjects ( = 53), patients with CT ( = 37), or NG rectal infection ( = 17) and patients with contemporary positivity for CT/NG ( = 18).

Rectal screening for carbapenemase-producing Enterobacteriaceae: a proposed workflow.

Genetic modification of primary human B cells to model high-grade lymphoma.

Sequencing studies of diffuse large B cell lymphoma (DLBCL) have identified hundreds of recurrently altered genes. However, it remains largely unknown whether and how these mutations may contribute to lymphomagenesis, either individually or in combination. Existing strategies to address this problem predominantly utilize cell lines, which are limited by their initial characteristics and subsequent adaptions to prolonged in vitro culture.

Understanding the Mechanisms of Resistance in -Positive NSCLC: From Tissue to Liquid Biopsy to Guide Treatment Strategy.

Liquid biopsy has emerged as an alternative source of nucleic acids for the management of Epidermal Growth Factor Receptor ()-mutant non-Small Cell Lung Cancer (NSCLC). The use of circulating cell-free DNA (cfDNA) has been recently introduced in clinical practice, resulting in the improvement of the identification of druggable mutations for the diagnosis and monitoring of response to targeted therapy. -dependent (T790M and C797S mutations) and independent (Mesenchymal Epithelial Transition [] gene amplification, Kirsten Rat Sarcoma [], Phosphatidyl-Inositol 4,5-bisphosphate 3-Kinase Catalytic subunit Alpha isoform [], and RAF murine sarcoma viral oncogene homolog B1 [] gene mutations) mechanisms of resistance to EGFR tyrosine kinase inhibitors (TKIs) have been evaluated in plasma samples from NSCLC patients using highly sensitive methods (i.

QuantiFERON-TB Performs Better in Children, Including Infants, than in Adults with Active Tuberculosis: a Multicenter Study.

Immunological tests, including the QuantiFERON-TB Gold In-Tube (QFT-IT) assay, represent an important aid for diagnosing active tuberculosis (TB) and latent TB infections in children, but concerns about their use in children <5 years of age persist. This is a multicenter retrospective study comparing a population of 226 children to 521 adults with pulmonary or extrapulmonary TB. The aim was to evaluate the QFT-IT performance, analyzing both qualitative and quantitative results, according to age, birthplace, and disease localization.

The aim of this review is to clarify the role of cross-linked Hyaluronic acid (HA) molecule as a tear supplement and to define its possible applications in dry eye disease. Current Literature about HA and its cross-linked derivatives has been examined. HA is superior in increasing the viscosity and stability of the tear film compared with other tear supplements such as polyvinyl alcohol, hydroxypropyl methylcellulose, carboximethyl cellulose and polyethylene glycol.

Overexpression of TK1 and CDK9 in plasma-derived exosomes is associated with clinical resistance to CDK4/6 inhibitors in metastatic breast cancer patients.

Purpose: Cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) improve progression-free survival (PFS) in patients with hormone receptor-positive (HR+) advanced breast cancer. However, a better knowledge of predictive biomarkers of response and resistance to CDK4/6i is needed. Therefore, the present article addresses the role of the mRNA expression of thymidine kinase 1 (TK1), CDK4, 6 and 9 in plasma-derived exosomes and their relevance in the pharmacologic activity of CDK4/6i.

Novel and safe single-dose treatment of cutaneous leishmaniasis with implantable amphotericin B-loaded microparticles.

The development of an effective amphotericin B (AmB) topical formulation to replace the systemically toxic injections currently used in cutaneous leishmaniasis (CL) treatment is challenging due to poor absorption through the skin. Aiming at an effective local chemotherapy, we designed PLGA (poly(lactide-co-glycolide acid) microparticles loaded with deoxycholate amphotericin B (d-AmB) for both macrophage intracellular targeting and sustained extracellular release. For that, d-AmB/PLGA microparticles with sizes ranging from 0.

The aim of our study was to assess risk factors associated with vitamin D deficiency among HIV-1-infected patients on combination antiretroviral therapy (cART). A retrospective, case-control study was conducted to assess risk factors associated with vitamin D deficiency among HIV-1-infected adults on stable cART. Vitamin D deficiency was defined as 25-OH vitamin D concentration <30 ng/mL.

ANKRD44 Gene Silencing: A Putative Role in Trastuzumab Resistance in Her2-Like Breast Cancer.

Trastuzumab is an effective therapeutic treatment for Her2-like breast cancer; despite this most of these tumors develop resistance to therapy due to specific gene mutations or alterations in gene expression. Understanding the mechanisms of resistance to Trastuzumab could be a useful tool in order to identify combinations of drugs that elude resistance and allow a better response for the treated patients. Twelve primary biopsies of Her2+/hormone receptor negative (ER-/PgR-) breast cancer patients were selected based on the specific response to neoadjuvant therapy with Trastuzumab and their whole exome was sequenced leading to the identification of 18 informative gene mutations that discriminate patients selectively based on response to treatment.

Comparative serum bactericidal activity of meropenem-based combination regimens against extended-spectrum beta-lactamase and KPC-producing Klebsiella pneumoniae.

Combination therapies are frequently used in the treatment of multidrug-resistant Klebsiella pneumoniae infection without consensus regarding which combination is the most effective. We compared bactericidal titres from sera collected from critically ill patients receiving meropenem plus tigecycline (n = 5), meropenem plus colistin (n = 5), or meropenem, colistin and tigecycline (n = 5) against K. pneumoniae isolates that included ESBL-producing (n = 7) and KPC-producing strains (n = 14) with varying sensitivity patterns to colistin and tigecycline.
