66%, and the average matrix effects (MEs) were 86.23-109.96%. The high extraction recoveries and acceptable MEs indicated that the pretreatment method was feasible. And the stability was acceptable under various storage conditions and processing procedures. The validated method was successfully applied to the multiple components-PK studies, which lay the foundation for further pharmacological and clinical research of PTC and may provide a reference for other traditional Chinese medicines.A stability-indicating HPLC method was developed for the simultaneous determination of paraben mixture and its degradation products in effervescent potassium chloride tablets. The chromatographic separation was achieved on a Waters Cortecs C18 column (2.7 μm, 4.6 × 150 mm) using gradient elution. The optimized mobile phase consisted of 0.1% orthophosphoric acid in purified water as solvent A and purified water, acetonitrile, and orthophosphoric acid (1009001, v/v) as solvent B. The flow rate was 0.8 mL/min, and column temperature was maintained at 35°C. The injection volume was 10 μL, and UV detection was carried out at 254 nm. The selectively developed method has optimal separation among p-hydroxybenzoic acid, methylparaben, ethylparaben, propylparaben, and butylparaben peaks in the presence of specified and unspecified degradation products in the determination of drug product. The mass balance obtained from forced degradation studies was ≥95% and thus proves the stability-indicating property of the developed method. The developed reversed-phase HPLC method has been validated according to the International Conference on Harmonization guidelines. The correlation coefficients for all the peaks were >0.9999. The results of the other validation parameters were found within the limits. Finally, the optimized method was used in the quality control lab for stability analysis.
We investigated the long-term outcomes of mitral valve replacement (MVR) in native mitral valve infective endocarditis (IE).

Multicentre, population-based cohort register study consisted of 1233 consecutive adult patients treated with first-time MVR in Finland. Mitral valve IE was diagnosed in 170 of these patients. Propensity score matching resulted in 134 pairs with balanced baseline characteristics. The median follow-up was 6.1years.

Pre-operative native mitral valve IE was associated with an increased hazard of 10-year mortality (38.8% vs 30.5%; HR 2.13; CI 1.17-3.85; P=.013) after MVR. Occurrence of major bleeding was higher in IE patients (26.0%) vs non-IE patients (23.4%) during the 10-year follow-up (HR 2.80; CI 1.01-7.77; P=.048). Hospital admission duration after MVR was longer in IE patients (median 28 vs 11days; P<.0001). Cumulative ischaemic stroke rate was similar between patient groups (12.1% in IE vs 15.1% in non-IE; P=.493). Re-sternotomy was performed in 13.4% of IE patients and 9.0% of non-IE patients (P=.261).

Patients with native mitral valve IE have a higher risk of death and major bleeding after MVR than matched patients without IE. Results highlight the importance of complication prevention in these patients.

To determine how registered nurses understood the teach-back method and whether such understanding translated to better evaluation of patients' understanding of discharge instructions.

The teach-back method helps nurses confirm whether the information provided to patients is understood. The current literature indicates the benefits of teach-back; however, nurses do not apply the method adequately during discharge teaching.

This study used a qualitative pretest-posttest design with an educational session.

A consecutive sampling method was used. Twelve nurses were interviewed using a discussion guide to gauge their understanding of the teach-back method during the period July to August 2016. This was followed by an educational session on the teach-back method. Nurses then implemented the method on the medical/surgical unit. A second interview was conducted using a questionnaire to evaluate participants' understanding of the method. Data were analyzed using Atlas.ti 7 software.

Participants' knowledge of the teach-back method increased. Participants identified benefits associated with the method, but time constraint was a concern.

The findings contribute to an understanding of the teach-back method by nurses. Patient care will benefit if the method is reinforced among nurses through continuing in-service education.

The aim of this study was to evaluate nursing students' perceptions of a patient safety culture in one university in Turkey.

The sample of this descriptive cross-sectional study consisted of 299 undergraduate nursing students. Data were collected by having participants complete the Patient Safety Culture Scale (PSCS) and a personal information form.

Participants' scores on the PSCS were found to be moderate, and no significant differences were found between participants' study levels. Female students and students who had willingly chosen the nursing profession obtained statistically significantly higher scores on the PSCS, indicating positive perceptions of a patient safety culture.

The inclusion of patient safety education and training of nurses in the nursing curriculum may contribute to students' development of a patient safety culture.

This study was aimed at evaluating mental wellbeing and health perception in the general population during the coronavirus disease 2019 (COVID-19) pandemic and at highlighting the correlation between them and selected variables.

This descriptive and cross-sectional study was carried out in 374 individuals, who were remotely administered two scales ("Perception of Health Scale [PHS]" and "Warwick-Edinburgh Mental Wellbeing Scale [WEMWBS]") and a demographic and clinical questionnaire.

PHS mean score was 53.24 ± 7.69 and the total WEMWBS score was 52.95 ± 10.75. A positive statistically significant correlation was found between PHS and WEMWBS (p < 0.05). Gender, marital status, and education levels conditioned mental well-being in a statistically significant. Suffering from a chronic disorder, COVID-19 symptoms, or having a family member affected by COVID-19 infection influenced the health perception.

Exposing the factors affecting the health and mental wellbeing perceptions of individuals, especially during the pandemic period, can guide policymakers.
