5% aqueous acetic acid (70 30, v/v). Separation was achieved within 10 minutes, and linearity was proven in the ranges of 0.05-50 and 0.05-30 μg mL-1 for OTC and BR, respectively. Diclofenac sodium was used as an internal standard. The proposed methods were validated in accordance with the FDA Center for Veterinary Medicine guidelines. Moreover, the performance and health and environmental impacts of the methods were evaluated using several greenness metrics, namely, the National Environmental Methods Index (NEMI), modified NEMI, Green Analytical Procedure Index (GAPI), Analytical Eco-Scale and Analytical GREEnness (AGREE) metric approaches. All the obtained results proved the validity of the developed methods concerning its performance and ecological effects. The methods can be used to investigate the presence of OTC residues in various marketed milk samples to maintain public health.
The risk factors for stroke in elderly patients with chronic kidney disease (CKD) are not well understood. This study aimed to explore the influence of systolic blood pressure (SBP) on the risk of stroke in a large cohort of elderly patients with stage 3-5 CKD.
We retrospectively identified 665 patients hospitalized in Beijing Friendship Hospital from January 2000 to December 2021. Patients were followed up until the occurrence of stroke or death. Multivariate logistic regression analysis and Cox proportional hazard models were used to analyze the risk factors for stroke according to the presence or absence of CKD. The association between CKD and stroke was further evaluated regarding the role of SBP in the hypertensive population.
In individuals with CKD, a J-shaped relationship was observed between SBP levels and the risk of stroke. Participants with CKD and an SBP less than 125 mmHg had a significantly higher cumulative stroke survival rate than those whose SBP was between 125 and 139 mmHg. The cumulative stroke survival rate increased progressively for those with SBP higher than 140 mmHg. This J-shaped relationship was not found in patients without CKD.
In elderly patients with CKD, those with the lowest BP are at increased risk for incident stroke. This phenomenon could be different from that in the general population.

Discharge from the emergency department (ED) involves a complex series of steps to ensure a safe transition to home and follow-up care. Preventable, discharge-related serious safety events (SSEs) in our ED highlighted local vulnerabilities. We aimed to improve ED discharge by implementing a standardized discharge process with emphasis on multidisciplinary communication and family engagement.
At a tertiary children's hospital, we used the model for improvement to revise discharge care. Interventions included a new discharge checklist, a provider huddle emphasizing discharge vital signs, and a scripted discharge review of instructions with families. We used statistical process control to evaluate performance. selleck compound Primary outcomes included elimination of preventable, discharge-related SSEs and Press Ganey survey results assessing caregiver information for care of child at home. A secondary outcome was number of days between preventable low-level (near-miss, no or minimal harm) events. Process measures included discharge checklist adoption and vital sign acquisition. Balancing measures were length of stay (LOS) and return rates.
Over the study period, there were no preventable SSEs and low-level event frequency improved to a peak of >150 days between events. Press Ganey responses regarding quality of discharge information did not change (62%). Checklist use was rapidly adopted, reaching 94%. Vital sign acquisition increased from 67% to 83%. There was no change in the balancing measures of median LOS or return visit rates.
The development and implementation of a standardized discharge process led to the elimination of reported discharge-related events, without increasing LOS or return visits.

The method involved sample preparation with acetonitrile extraction and clean-up, and separation in the LC using a C18 column. The orbital ion trap MS was operated at a resolution of 35 000 FWHM in selected ion monitoring mode. An ion source with heated electrospray ionization was used in positive ionization mode. The samples were prepared by solid-phase extraction. The limit of quantification of steroid hormones in fish samples was 2 μg kg-1. Good linearity was observed since correlation coefficients were more than 0.99 for all compounds. Recoveries of spiked fish samples (2 μg kg-1 and 20 μg kg-1) ranged from 80.8% to 112.6% with relative deviations less than 15%. The method was successfully applied to detect steroid hormones in real farmed fish samples at the μg kg-1 level.A pH-responsive cascade nanoplatform based on ZIF-8 disintegrates in the weakly acidic tumor microenvironment to release MnO2, CaO2 and Ce6. The drugs can cyclically generate O2 for sonodynamic therapy, consume glutathione to tune the redox hemostasis, and produce cytotoxic ˙OH to kill tumor cells via chemical dynamics therapy.The accumulation and deposits of amyloid beta (Aβ) peptide are an important pathological hallmark of Alzheimer's disease (AD). The development of multifunctional agents that can effectively clear Aβ aggregates is one of the potential strategies to treat AD. Herein, aptamer conjugated polydopamine-coated gold nanoparticles (Au@PDA-Apt NPs) for targeting Aβ1-40 peptides were designed. Au@PDA-Apt NPs exhibited a strong capability to inhibit Aβ1-40 monomer fibrillization and disaggregate mature Aβ1-40 fibrils. In addition, Au@PDA-Apt NPs could effectively alleviate Aβ1-40-triggered cytotoxicity. Importantly, AFM quantitative nanomechanical measurements indicated that Au@PDA-Apt NPs could prevent cell membrane damage and decrease of cell mechanical properties caused by Aβ1-40 aggregation. Taken together, this study provided a new dual-action nanoplatform for Aβ-targeted AD therapy.
This study aimed to investigate the viewpoints of the main stakeholders of the Iranian healthcare system about the overutilization of hospital services and strategies to eliminate or reduce it in Iran.
This is a qualitative study and thematic data analysis using face-to-face semi-structured interviews and Focus Group Discussions (FGDs). We conducted eight interviewers and two FGDs with hospital stakeholders including faculty members, insurance organizations' authorities, experienced hospital administrative staff, hospital managers, and health-care providers.
The factors leading to the overutilization of hospital services were categorized into four main themes including site of service, quality, supplier push, and demand pull. Strategies for eliminating or reducing the overutilization of hospital services are also identified based on the influential factors.
Addressing overutilization of hospital services in the health system and adherence to policies for reducing or eliminating overutilization is a way to make preventive strategies to overcome overutilization. Developing a national plan to integrate utilization management into health system programs is a strategy to combat overutilization in various levels of the health system including hospital setting.

A bronchiolitis integrated care pathway (BICP) proved useful in reducing the use of unnecessary medications at a local level. The aim of this study was to reduce overtreatment by scaling up the BICP across our regional health service in the 2019 and 2020 bronchiolitis season.
We conducted a quality improvement (QI) initiative in 115 primary care (PC) centers and 7 hospitals in the Basque Country, Spain, from October 2019 to March 2020. The primary outcome measure was the percentage of children prescribed salbutamol comparing the rate to that in the previous bronchiolitis season (October 2018-March 2019). Secondary outcomes were the use of other medications. Balancing measures were hospitalization and unscheduled return rates.
We included 8153 PC visits, 3424 emergency department (ED) attendances, and 663 inpatient care episodes, of which 3817 (46.8%), 1614 (47.1%), and 328 (49.4%) occurred in the postintervention period, respectively. Salbutamol use decreased from 27.1% to 4.7%, 29.5% to 3.0%, and 44.4% to 3.9% (P < .001) in PC centers, Eds, and hospital wards, respectively. In PC, corticosteroid and antibiotic prescribing rates fell from 10.1% to 1.7% and 13.7% to 5.1%, respectively (P < .001). In EDs and hospital wards, epinephrine use rates fell from 14.2% to 4.2% (P < .001) and 30.4% to 19.8% (P = .001), respectively. No variations were noted in balancing measures.
The scaling up of the BICP was associated with significant decreases in the use of medications in managing bronchiolitis across a regional health service without unintended consequences.

The present study investigates whether modifiable behavioral factors of current cigarette smoking, heavy alcohol consumption, and regular exercise are associated with risk of lower extremity amputation (LEA) in diabetic patients.
A total of 2,644,440 diabetic patients (aged ≥20 years) was analyzed using the database of the Korean National Health Insurance Service. Cox proportional hazard regression was used to assess adjusted hazard ratios (HRs) for the behavioral factors with risk of LEA under adjustment for potential confounders.
The risk of LEA was significantly increased by current cigarette smoking and heavy alcohol consumption (HR, 1.436; 95% confidence interval [CI], 1.367 to 1.508 and HR, 1.082; 95% CI, 1.011 to 1.158) but significantly decreased with regular exercise (HR, 0.745; 95% CI, 0.706 to 0.786) after adjusting for age, sex, smoking, alcohol consumption, exercise, low income, hypertension, dyslipidemia, body mass index, using insulin or oral antidiabetic drugs, and diabetic duration. A synergistically increased risk of LEA was observed with larger number of risky behaviors.
Modification of behaviors of current smoking, heavy alcohol intake, and exercise prevents LEA and can improve physical, emotional, and social quality of life in diabetic patients.
