Oral health is of particular importance in patients with heart valve diseases because of the risk of infective endocarditis. Recommendations for antibiotic prophylaxis before dental procedures have been restricted, but the modalities of oral evaluation and dental care are not detailed in guidelines. Therefore, a multidisciplinary working group reviewed the literature to propose detailed approaches for the evaluation and management of buccodental status in patients with valvular disease. Simple questions asked by a non-dental specialist may draw attention to buccodental diseases...

The emergence of antibiotic resistance in bacteria has caused many healthcare problems and social burdens. Herein, we designed and studied self-assembled peptide amphiphiles (PAs) functionalized with a heparin-binding Cardin-motif peptide (sequence (AKKARK)2) to combat bacteria drug resistance. These amphiphilic Cardin antimicrobial peptides (ACA-PAs) self-assembled into nanorods (7-10 nm in diameter) with the cationic Cardin-motif peptide exposed on the surface. The ACA nanorods formed above the critical micelle concentration (CMC) of 45 µM into a β-sheet secondary structure...

BACKGROUND: Immunoglobulin D (IgD) is an enigmatic antibody isotype best known when co-expressed with IgM on naïve B cells. However, elevated soluble IgD (sIgD) and increased IgD(+)IgM(-) B cell populations have been described in the human upper respiratory mucosa. OBJECTIVE: We assessed whether levels of sIgD and IgD(+) B cells are altered in nasal tissue from patients with chronic rhinosinusitis (CRS). We further characterized IgD(+) B cell populations and explored clinical and local inflammatory factors associated with tissue sIgD levels...

BACKGROUND: Autophagy is an intracellular bulk self-degrading process in which cytoplasmic contents of abnormal proteins and excess or damaged organelles are sequestered into autophagosomes, and degraded upon fusion with lysosomes. Although autophagy is generally considered to be pro-survival, it also functions in cell death processes. We recently reported on the hippocampal higher vulnerability to cerebral ischemia in mice lacking the circadian clock protein PERIOD1 (PER1), a phenomenon we found to be linked to a PER1-dependent modulation of the expression patterns of apoptotic/autophagic markers...

BACKGROUND AND AIMS: H. pylori eradication is strongly affected by various factors, including the ongoing antibiotic resistance. We describe a "real life" scenario in patients managed for H. pylori-related conditions, living in a southern Italian region (Apulia), an area with clarithromycin resistance >15%. METHODS: 2,224 subjects were studied in two tertiary referral centers in Apulia. Analyses included: reason for referral, H. pylori infection rates (13C-urea breath test - UBT or upper endoscopy), and eradication rates following distinct regimens previously prescribed or prospectively prescribed (such as the bismuth-based quadruple therapy Pylera®, recently marketed in Italy)...

BACKGROUND: Minority resistant M. tuberculosis subpopulations can be associated with phenotypic resistance, but are poorly detected by Sanger sequencing or commercial molecular diagnostic assays. The role of targeted next generation sequencing (NGS) in resolving these minor variant subpopulations is unclear. METHODS: We utilized Single Molecule-Overlapping Reads (SMOR), a targeted NGS approach that dramatically reduces sequencing error, to analyze primary cultured isolates phenotypically resistant to rifampin, fluoroquinolones, or aminoglycosides, but for which Sanger sequencing found no resistance-associated variants (RAVs) within respective resistance determining regions (RDRs) (Study Group)...

BACKGROUND: Hidradenitis suppurativa is a painful and disfiguring chronic inflammatory condition affecting both men and women. Medical treatments, such as antibiotics and immunosuppressive agents, are often ineffective. Over time, patients can suffer from recurrent abscesses, chronic purulent drainage, scarring, and contractures that can only be corrected by surgical excision. There is no agreement, however, on the best way for the surgeon to manage this condition. The purpose of this review is to describe the results of surgical treatment of this condition in a large cohort of patients managed by local excision of hidradenitis, healing by secondary intention and reoperation as needed...

Human organic anion transporter 3 (hOAT3) is localized at the basolateral membrane of renal proximal tubule cells and facilitates renal secretion of numerous clinical drugs, including anti-HIV therapeutics, anti-tumor drugs, antibiotics, antihypertension drugs, and anti-inflammatories. In the present study, we explored the role of serum and glucocorticoid-inducible kinase 1 (sgk1) in the regulation of hOAT3. We showed that over-expression of sgk1 in hOAT3-expressing cells stimulated hOAT3 transport activity by enhancing the transporter expression at the plasma membrane, kinetically reflected as an increased maximal transport velocity Vmax without substantial change in substrate-binding affinity Km ...

Due to the increasing selection and prevalence of multidrug-resistant gram-negative bacteria and the insufficient development of novel antibiotics, the responsible and prudent use of the available antimicrobial drugs is of major importance. In Germany the rational use of anti-infectives considering the local antimicrobial resistance situation is defined in the infection protection act of 2011. An important tool to follow legal regulations and to improve the treatment of bacterial infections is the antimicrobial stewardship (AMS) concept...

Despite advances in understanding and management, paediatric osteoarticular infections continue to pose diagnostic difficulties for clinicians. Delays in diagnosis can lead to potentially devastating morbidity.No single investigation, including joint aspiration, is sufficiently reliable to diagnose conclusively paediatric bone and joint infection. Diagnosis should be based on a combination of clinical signs, imaging and laboratory investigations. Algorithms should supplement, and not replace, clinical decision making in all cases...

Diverse organisms secrete redox-active antibiotics, which can be used as extracellular electron shuttles by resistant microbes. Shuttle-mediated metabolism can support survival when substrates are available not locally but rather at a distance. Such conditions arise in multicellular communities, where the formation of chemical gradients leads to resource limitation for cells at depth. In the pathogenic bacterium Pseudomonas aeruginosa PA14, antibiotics called phenazines act as oxidants to balance the intracellular redox state of cells in anoxic biofilm subzones...
