Myocarditis has been reported following the second dose of COVID-19 mRNA vaccination. Whether administration of additional doses of COVID-19 vaccines further increases the risk of myocarditis is unknown.

We included individuals who received one to three doses of BNT162b2 or mRNA-1273 mRNA vaccine between 12/14/2020 and 2/18/2022. Myocarditis within 21days of vaccine administration was identified using electronic medical records. Incidence rate ratios were calculated by comparing the observed incidence with the expected incidence from the same population during a 365-day baseline period.

Of 3,076,660 KPSC members who received at least one dose of COVID-19 mRNA vaccines, 2,916,739 (94.5%) received at least two doses, and 1,146,254 (47.0%) received three doses. The incidence rate ratio for myocarditis was 0.86 (95% CI 0.31-1.93) for the first dose, 4.22 (95% CI 2.63-6.53) for the second dose, and 2.61 (1.13-5.29) for the third dose. Most myocarditis cases following the second and third dose occurred within seven days of vaccination.

Myocarditis was a rare event observed after the second or third dose of vaccination. Most cases presented within seven days of vaccination. The incidence of myocarditis following the third dose was not significantly higher than that observed after the second dose.

The role of relaxin-2 as a circulating marker in heart failure (HF) with preserved ejection fraction (HFpEF) is poorly understood. We aimed to characterize relaxin-2 circulating levels in a population of chronic HFpEF patients and their association with long-term prognosis.

Relaxin-2 serum levels were measured in 85 chronic HFpEF patients from a prospective cohort study (NETDiamond). Clinical, imaging, and analytical data were compared across relaxin-2 tertiles. The primary outcome was a composite of cardiovascular death, HF hospitalisation, acute HF episode or diuretic intensification and the secondary outcome a composite of cardiovascular death and total HF hospitalisations. Cox regression and negative binomial models were used to assess the relation between relaxin-2 and the outcomes.

Relaxin-2 levels were positively associated with left atrial volume, left ventricular mass and peripheral oedema, and negatively associated with ischemic heart disease and statin use. Higher relaxin-2 levels were associated with an increased risk of primary outcome, even after adjustment for age, B-type natriuretic peptide (BNP) and glomerular filtration rate (eGFR) (adjusted HR=2.80, 95%CI 1.4-7.3, p=0.034 for tertile 3). They were also associated with the occurrence of the secondary outcome (Incidence Rate Ratio=5.28, 95%CI 1.2-23.2, p=0.027), but this significance was lost when simultaneously adjusted for BNP and eGFR.

In chronic HFpEF patients, higher relaxin-2 circulating levels were associated with left chambers remodelling, congestion, and adverse prognosis. These findings support a potential role for relaxin-2 as a pathophysiological agent and as a circulating biomarker in HFpEF.

Left ventricular (LV) filling pressures are normal in idiopathic pulmonary arterial hypertension (IPAH). However, direct and indirect interactions between the RV and LV can affect LV performance. We explored LV strain and LV intra-ventricular dyssynchrony in IPAH using feature tracking CMR (CMR-FT).

Seventy IPAH patients and 40 healthy volunteers were included. Cynarin Patients underwent CMR and right heart catheterisation. The 4-chamber cine was used to calculate LV longitudinal strain (Ell
). LV circumferential (Ecc
) and radial strain (Err
) were derived from a short axis cine. LV longitudinal, circumferential and radial intra-ventricular dyssynchrony indices were calculated.

There were no differences between the IPAH and healthy volunteer group in LV ejection fraction (66.1% vs 64.2% p=0.6672). Ecc
(-29.1 vs -32.1 p=0.0323) and Ell
(-16.6 vs -23.7 p<0.0001) were lower in IPAH. In patients with more severe disease, there was greater impairment of Err
compared to mild disease (50.9 vs 87.5 P<0.0001). LV synchrony was impaired in all directions in IPAH. Err
was associated with RV ejection fraction (r=0.66), RV end-systolic volume index (r=-0.59), pulmonary vascular resistance (PVR)(r=0.51) and stroke volume index (SVI)(r=0.44). In a multivariate model with age, SVI and PVR, Err
(HR 0.970 p=002) and radial dyssynchrony (HR 3.759 p<0.0001) independently predicted survival.

In IPAH, LV is dyssynchronous with impaired function. Measures of LV strain and intraventricular synchrony were associated with known markers of disease severity. These LV variables which are likely to be related to ventricular interaction, may add incremental value to known prognostic variables in IPAH.

The prepared composite and constituents were characterized for structure, morphology, and physical properties with the help of fourier transform infrared, X-ray diffraction, Scanning electron microscope, and other relevant standard methods. The obtained results revealed the formation of porous, electrical conductivity, structurally functionalized, responsiveness composite due to molecular engineering, and structural synergism for sensing applications. Further, the film of the prepared composite was explored as the electrode for nonenzymatic potentiometric sensing of residual chlorpyrifos in synthetic and natural sample i.e., tap water, soil, mango, and cabbage. The sensor exhibits a wider sensing range 1.0-120.0 μM, improved sensitivity 1.8790 mV·μM-1·cm-2, detection limit 0.375 μM, response time 120 s, recovery time 16 s with 99.80 % accuracy, and stability of 72 days at neutral 7.0 pH and ambient temperature i.e. 25 °C. Further, the sensing mechanism has been also explained on the basis of structural change in CPF and electrode materials due to their surface interaction along with formation induced electrode potential.For the greater utilization of β-carotene in antioxidant material, β-carotene-loaded emulsion stabilized by alkali lignin (AL) was successfully electrospinning with poly (vinyl alcohol) (PVA) (PVA/AL/β-carotene nanofiber). Transmission electron microscopy demonstrated the core-shell structure of nanofiber with the average diameter being 356.31 nm, and 85.7 % of β-carotene was effectively encapsulated into the core section. Fourier transform infrared spectra and differential scanning calorimetry revealed the good compatibility and decreased crystallinity of β-carotene, favoring its stability and solubility, respectively. As expected, the PVA/AL/β-carotene nanofiber exhibited higher antioxidant activity than free β-carotene due to the protection of AL matrix and the special structure of nanofiber, as the DPPH free radical scavenging rate being 90.7 % at 7th day. The sustained release behavior of β-carotene and AL from fiber followed Fickian diffusion model, contributing to the greater protection for fish oil than that of emulsion. Thus, this study provides an approach to develop hydrophobic compounds-loaded emulsion electrospun antioxidant material with controlled release property and enhanced activity.Chitosan-based nanogels are effective carriers for drug delivery due to their biocompatibility and biodegradability. However, the chemically cross-linked nanogels usually require complicated procedures or tough conditions. Herein, we report a simple approach to generate chitosan-based nanogels by photo-crosslinking of poor solvent-induced nanoaggregates without requiring any emulsifying agent, catalyst, or external crosslinker. O-nitrobenzyl alcohol-modified carboxymethyl chitosan was synthesized and self-crosslinked into the nanogels in a mixed solution of ethanol and water under 365 nm light irradiation due to UV-induced primary amine and o-nitrobenzyl alcohol cyclization. The nanogels (CMC-NBA NPs) and lactobionic acid-decorated nanogels (LACMC-NBA NPs) displayed a uniform diameter (~200 nm) and excellent stability under physiological conditions. Notably, the nanogels exhibited a high loading content (~28 %) due to π-π stacking and electrostatic interactions between doxorubicin (DOX) and the carriers. These DOX-loaded nanogels showed rapid drug release under slightly acidic conditions. The cell and animal experiments confirmed that LACMC-NBA NPs increased cellular uptake, improved cytotoxicity in tumor cells, and enhanced growth inhibition in vivo than CMC-NBA NPs. Thus, these photo-crosslinked nanogels possess great potential for DOX delivery.Antioxidants fucoidans from three seaweeds, Undaria pinnatifida (FUP), Macrocystis pyrifera (FMP) and Fucus vesiculosus (FFV) are sold commercially. However, it is unclear which fucoidan is the most potent antioxidant. Therefore, our objective was to compare the antioxidant activities of these fucoidans. For this purpose, six in vitro antioxidant tests were used, total antioxidant capacity, hydroxyl radical scavenging assay, ferrous and cupric chelating assay, reducing power and H2O2 scavenging assay. The data showed that the fucoidans had a low capacity to donate electrons, and a low capacity to chelate metals. The best activity obtained was in the scavenging of hydroxyl radical. When macrophages were exposed to H2O2 and fucoidans, MTT and live/dead assays showed that all fucoidans protected cells from oxidative damage. The survival rate of zebrafish embryos was significantly higher when exposed to H2O2 and fucoidans than H2O2 alone. In summary, the fucoidans evaluated were ranked according to their antioxidant activity as follows FMP > FFV > FUP, and the results suggest that these fucoidans, mainly FMP, can be used in the formulation of medicines/foods.Nanocellulose has broad and promising applications owing to its low density, large specific surface area, high mechanical strength, modifiability, renewability. Recently, nanocellulose has been widely used to fabricate flexible, durable and environmental-friendly sensor substrates. In this contribution, the construction and characteristics of nanocellulose-based sensors are comprehensively reviewed. Various nanocellulose-based sensors are summarized and divided into colorimetric, fluorescent, electronic, electrochemical and SERS types according to the sensing mechanism. This review also introduces the applications of nanocellulose-based sensors in the fields of biomedicine, environmental monitoring, food safety, and wearable devices.
