Pediatric pneumococcal conjugate vaccines (PCVs) introduction has directly and indirectly reduced pneumococcal pneumonia and invasive disease caused by PCV-covered serotypes among children and adults globally. In Japan, both PCV7 and PCV13 were introduced into the national immunization program (NIP) for children in 2013. However, the long-term impact of PCV use in children on adult pneumococcal pneumonia in Japan remains unclear.

We assessed serotypes isolated from adult pneumococcal pneumonia patients (in- and outpatients) in two multicenter observational studies in Japan 2011-2014 and 2016-2020. The latter study period was divided into two periods to evaluate changes after PCV introduction in children. The Quellung reaction was used to determine serotypes. We evaluated trends of individual and vaccine-covered serotypes over three periods and assessed the difference in changes by patient group before and after the introduction of pediatric PCVs.

A total of 650 patients were enrolled 224, 322, and 104 ition strategy for older adults requires discussion.
The proportion of adult pneumococcal pneumonia caused by PCV13 serotypes in Japan declined after pediatric PCVs introduction into NIP, possibly due to indirect effects of pediatric PCVs. However, use of new PCVs in Japanese adults may potentially prevent additional pneumococcal pneumonia cases. Now, pneumococcal vaccination strategy for older adults requires discussion.In recent years, several advances have been observed in vaccinology especially for neglected tropical diseases (NTDs). One of the tools employed is epitope prediction by immunoinformatic approaches that reduce the time and cost to develop a vaccine. In this scenario, immunoinformatics is being more often used to develop vaccines for NTDs, in particular visceral leishmaniasis (VL) which is proven not to have an effective vaccine yet. Based on that, in a previous study, two predicted T-cell multi-epitope chimera vaccines were experimentally validated in BALB/c mice to evaluate the immunogenicity, central and effector memory and protection against VL. Considering the results obtained in the mouse model, we assessed the immune response of these chimeras inMesocricetus auratushamster, which displays, experimentally, similar pathological status to human and dog VL disease. Our findings indicate that both chimeras lead to a dominant Th1 response profile, inducing a strong cellular response by increasing the production of IFN-γ and TNF-α cytokines associated with a decrease in IL-10. Also, the chimeras reduced the spleen parasite load and the weight a correlation between protector immunological mechanisms and consistent reduction of the parasitic load was observed. Our results demonstrate that both chimeras were immunogenic and corroborate with findings in the mouse model. Therefore, we reinforce the use of the hamster as a pre-clinical model in vaccination trials for canine and human VL and the importance of immunoinformatic to identify epitopes to design vaccines for this important neglected disease.
Hypoxaemia during general anaesthesia can cause harm. Apnoeic oxygenation extends safe apnoea time, reducing risk during airway management. We hypothesised that low-flow nasal oxygenation (LFNO) would extend safe apnoea time similarly to high-flow nasal oxygenation (HFNO), whilst allowing face-mask preoxygenation and rescue.

A high-fidelity, computational, physiological model was used to examine the progression of hypoxaemia during apnoea in virtual models of pregnant women in and out of labour, with BMI of 24-50 kg m
. Subjects were preoxygenated with oxygen 100% to reach end-tidal oxygen fraction (FE'O
) of 60%, 70%, 80%, or 90%. When apnoea started, HFNO or LFNO was commenced. To simulate varying degrees of effectiveness of LFNO, periglottic oxygen fraction (FgO
) of 21%, 60%, or 100% was configured. HFNO provided FgO
100% and oscillating positive pharyngeal pressure.

Application of LFNO (FgO
100%) after optimal preoxygenation (FE'O
90%) resulted in similar or longer safe apnoea times than HFNO FE'O
80% in all subjects in labour. For BMI of 24, the time to reach SaO
90% with LFNO was 25.4 min (FE'O
90%/FgO
100%) vs 25.4 min with HFNO (FE'O
80%). selleck chemical For BMI of 50, the time was 9.9 min with LFNO (FE'O
90%/FgO
100%) vs 4.3 min with HFNO (FE'O
80%). A similar finding was seen in subjects with BMI ≥40 kg m
not in labour.

There is likely to be clinical benefit to using LFNO, given that LFNO and HFNO extend safe apnoea time similarly, particularly when BMI ≥40 kg m
. Additional benefits to LFNO include the facilitation of rescue face-mask ventilation and ability to monitor FE'O
during preoxygenation.

Abnormal activation of RAAS contributes to development of cardiovascular disease, including heart failure, cardiac hypertrophy, hypertension, and atherosclerosis. Although several key RAAS enzymes and peptide hormones have been thoroughly investigated, the role of angiotensinogen-the precursor substrate of the RAAS pathway-remains less understood. The study of angiotensinogen single-nucleotide polymorphisms (SNPs) has provided insight into associations between angiotensinogen and hypertension, congestive heart failure, and atherosclerotic cardiovascular disease. Targeted drug therapy of RAAS has dramatically improved clinical outcomes for patients with heart failure, myocardial infarction, and hypertension. However, all such therapeutics block RAAS components downstream of angiotensinogen and elicit compensatory pathways that limit their therapeutic efficacy as monotherapy. Upstream RAAS targeting by an angiotensinogen inhibitor has the potential to be more efficacious in patients with suboptimal RAAS inhibition and has a better safety profile than multiagent RAAS blockade. Newly developed therapeutics that target angiotensinogen through antisense oligonucleotides or silencer RNA technologies are providing a novel perspective into the pathobiology of angiotensinogen and show promise as the next frontier in the treatment of cardiovascular disease.Granzyme B (GrB) is a pivotal killer factor in immunotherapy whose application is limited by hyposensitivity and unsatisfactory cellular uptake by tumor cells. In this study, it was proved that SerpinB9 (Sb9) downregulation can enhance the GrB susceptibility of tumor cells. Moreover, a nanocarrier fused with M1 macrophage exosomes (M1 Exo) and photothermal sensitive liposomes was constructed to efficiently transport GrB and siRNA of Sb9 to the cells. The nanocarrier is characterized by cascade tumor targeting acquired by photothermal effect-triggered increased expression of vascular cell adhesion molecule-1 (VCAM-1) in tumor tissue. Furthermore, the innate cytokines in M1 Exo are capable of regulating the tumor microenvironment by repolarizing M2 macrophages to the M1 type. Collectively, the multifunctional nanoplatform (S+G@ELP) enhances the lethality of GrB to tumor cells, activates a widespread immune response uniting with photothermal therapy (PTT), restrains the tumor progression and metastasis effectively, which is expected to provide new insights into GrB-based combinational tumor therapy.The postoperative recurrence and metastasis of triple negative breast cancer (TNBC) remain one fatal reason for the failure of clinical treatments. Although the rise of immunotherapy has brought hopes for reducing postoperative recurrence and potential metastasis, the low immune response and immunosuppression of tumor microenvironment (TME) still restrain its extensive application. Herein, we reported a boosting strategy by improving immunogenicity and reversing suppressive TME to realize efficient immunotherapy of TNBC. In this work, a CaCO3 biomineralized hydrogel DC vaccine was synthesized by fixing the membrane proteins of 4T1 cells-DCs fusion cells (FP) into biomineralized silk fibroin hydrogel. On one side, the FP-containing biomineralized hydrogel vaccine (SH@FP@CaCO3) has increased immunogenicity by providing a wide variety of tumor-associated antigens (TAAs) and realizing long-term protein release for DCs maturation and T cell activation. On the other side, the introduction of CaCO3 would increase the pH of TME and promote the polarization of M2-type macrophages to M1-type macrophages, thus reversing the immune-inhibitory microenvironment and relieving the immunosuppressive effect on T cells. The results indicate that the biomineralized hydrogel vaccine shows excellent immune activation effects by simultaneously enhancing the immunogenicity and reversing the immunosuppression TME, which provides a promising strategy for cancer immunotherapy.
Healthcare-associated transmission of methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa occurs for people with cystic fibrosis (CF), but CF programs lack a process to monitor incidence rates (IRs). We assessed predictors of incident infections and created a model to determine risk-adjusted IRs for CF programs.

Using the CF Foundation Patient Registry data for all patients from 2012 to 2015, coefficients for variables that predicted IRs were estimated. Hazard functions were then used to predict IRs of MRSA and P. aeruginosa for CF programs based on their patient and program characteristics. Predicted IRs were compared with observed IRs over multiple time intervals.

Multiple patient and program characteristics were identified as predictors of observed IRs. Our model's predicted IRs closely aligned with observed IRs for most CF programs. Alarm values (defined as observed IR > 95% confidence interval of predicted IR) were found at 5.9%, 5.9%, 6.0% (adult, pediatric, affiliate) of programs for MRSA and 3.0%, 1.7%, 0.0% (adult, pediatric, affiliate) of programs for P. aeruginosa.

We found patient and program characteristics that predicted MRSA and P. aeruginosa IRs. Our model accurately predicted risk-adjusted IRs of MRSA and P. aeruginosa. CF programs could use our model to monitor their IRs and potentially improve infection prevention and control.

Epicardial adipose tissue (EAT) around the left atrium (LA) can change the electric conduction of the LA, potentially leading to atrial fibrillation (AF).

The aim of this study was to evaluate whether an association existed between EAT and the electrophysiological properties of adjacent atrial myocardium in patients with AF.

A total of 201 consecutive patients referred for initial AF catheter ablation were prospectively included. A preprocedural computed tomography scan was performed to assess total and LA-EAT parameters. Detailed point-by-point voltage mapping using an electroanatomical mapping system was realised to assess the LA low-voltage zone (LVZ), defined as an area with bipolar electrograms ≤0.5 mV during sinus rhythm.

Ninety-one (91) patients (45.3%) presented at least one LVZ. They had a significantly more severe AF pattern (p=0.04) than patients without LVZ, and little difference existed with regard to other clinical variables. Patients with LVZ presented significantly more total EAT volume (162.
