Invasive meningococcal disease is a major cause of meningitis in children. An investigational meningococcal (serogroups A, C, Y, and W) tetanus toxoid conjugate vaccine (MenACYW-TT) could offer protection against invasive meningococcal disease in this population. This phase III study assessed the immunogenicity and safety of MenACYW-TT in children compared with a licensed quadrivalent meningococcal vaccine conjugated with diphtheria protein CRM197 (MenACWY-CRM).

Healthy children 2-9 years of age in the United States, including Puerto Rico, were randomized (11) to receive MenACYW-TT (n = 499) or MenACWY-CRM (n = 501) (NCT03077438). Meningococcal antibody titers to the 4 vaccine serogroups were measured using a serum bactericidal antibody assay with human complement (hSBA) before and at day 30 after vaccination. Noninferiority between the vaccine groups was assessed by comparing seroresponse rates (postvaccination titers ≥116 when prevaccination titers were <18, or ≥4-fold increase if prevaccination titers were ≥18) to the 4 serogroups at day 30. Safety was monitored.

The proportion of participants achieving seroresponse at day 30 in the MenACYW-TT group was noninferior to the MenACWY-CRM group (A 55.4% vs. 47.8%; C 95.2% vs. 47.8%; W 78.8% vs. 64.1%; Y 91.5% vs. 79.3%, respectively). Geometric mean titers for serogroups C, W, and Y were higher with MenACYW-TT than for MenACWY-CRM. Both vaccines were well-tolerated and had similar safety profiles.

MenACYW-TT was well-tolerated in children and achieved noninferior immune responses to MenACWY-CRM against each of the 4 vaccine serogroups.

The duration of antibiotic treatment after resolution of empyema in children is variable. We evaluated the efficacy and safety of a protocol-driven antibiotic regimen aimed to decrease antibiotic duration following treatment with fibrinolysis.

Our institutional protocol consisted of 7 further days of antibiotics upon removal of the thoracostomy tube, with the patient being afebrile, off supplemental oxygen, and having negative cultures. A prospective observational study was then performed between September 2014 and March 2019. Empyema recurrence and antibiotic-related complications were recorded. Results were compared with previously published data from the preprotocol era.

A total of 37 patients were included. Mean total duration of antibiotics decreased from 26 ± 6.5 days in the preprotocol group to 22 ± 9.7 days in the postprotocol group (P = 0.004). This resulted in a significant decrease in hospital stay from the preprotocol cohort to the postprotocol cohort, respectively (9.3 ± 4.8 d versus 6.8 ± 3.1 d, P = 0.003). Sixty-two percentage of the patients were intended to treat according to the protocol, with a 50% adherence rate. Patients in which the protocol was followed had an average of 2.8 fewer days of antibiotics after discharge (P = 0.004), although overall duration was not statistically different. Significantly fewer antibiotic-related complications were noted after protocol initiation. There was no difference in empyema recurrence or readmissions.

Institution of a protocol-driven approach to antibiotic duration following resolution of pleural space disease may reduce antibiotic duration and complications without reducing efficacy.

Aberrant subclavian artery (ASCA) represents one of the most common congenital vascular anomalies of the aortic arch. The majority of ASCAs are associated with an aneurysm which occurs at their origin from the descending thoracic aorta, namely, the Kommerell's diverticulum. In this review, we discuss recent data with regards to indications of treatment and surgical management of these anatomical variants.

Various surgical methods have been described for the repair of ASCA and Kommerell's diverticulum. Traditionally, treatment included open surgery; however, recent studies describe a shift of conventional treatment to more hybrid or endovascular approaches. Orelabrutinib order The heterogeneity in the anatomy and presentation of these clinical entities as well as patient-related factors have prevented conduction of randomized trials for the best available modality of treatment. This dearth of literature is well depicted in the current guidelines.

The optimal surgical procedure has to be tailored to every patient according to the presentation, individual anatomy, and patient's risk profile. Conventional surgery for ASCA and Kommerell's diverticulum has acceptable mortality and complication rates, whereas hybrid repairs report encouraging results. Further studies are required to provide sufficient evidence which will formulate a clear frame of treatment indications and optimal surgical methods, as well as evaluate long-term results following hybrid repair.

To provide a summary and critical appraisal of recent literature pertaining to very late adverse events (>1 year) after revascularization with percutaneous coronary intervention (PCI) with coronary stents.

Recent studies, including an individual patient-level pooled analysis of randomized trials and network meta-analysis have demonstrated that all coronary stents, including contemporary drug-eluting stents (DES), are associated with an ongoing risk of major adverse cardiovascular events related to the stented region beyond the first year after stent implantation, with rates ranging from 2 to 3% per year for at least 4 years. Patients also remain at additional risk for events originating outside the stented segments because of progressive de novo atherosclerotic disease.

Despite improvements in the management of coronary artery disease, patients remain at risk for very late adverse cardiovascular events both arising from the stented regions and other untreated segments of the coronary tree. Further advancements focused on primary prevention, stent design and procedural technique, and secondary prevention will be crucial to reducing rates of very late events and improving symptoms and prognosis of patients after PCI.
