Synthesis of salcaprozate sodium and its significance in enhancing pancreatic kininogenase absorption performance.

We conducted pharmacokinetic research wherein salcaprozate sodium (SNAC) was utilized as a penetration enhancer by incorporating it into pancreatic kininogenase (PK) to improve the bioavailability of pancreatic kininogenase enteric-coated tablets. We conducted invitro studies on PK using the Caco-2 cell model and quantified PK levels using the enzyme-linked immunosorbent assay (ELISA) method. We conducted methodological verification by blending SNAC and PK powders into enteric-coated capsules, and studied the pharmacokinetic characteristics. Based on the PK transport assay, the cumulative permeation rates of the test group that employed a SNAC to PK ratio of 32:1, 16:1, 8:1, 4:1, and 2:1 were 13.574%, 7.597%, 10.653%, 3.755%, and 2.523%, respectively. We conducted a uniformity test on the powder that contained a blend of SNAC and PK. The relative standard deviations (RSDs) for both the power containing SNAC and the power not containing SNAC were less than 10%. Based on the methodological verification, invivo pharmacokinetic study of PK met the experimental requirements. As indicated by the results of invivo pharmacokinetic research on rats, the test group (This group used SNAC) had a PK AUC0-12 h of 5679.747 ng/L*h and t1/2 of 4.569 h, while the control group (This group did not use SNAC) had a PK AUC0-12 h of 4639.665 ng/L*h and t1/2 of 3.13 h. This study has established a low-cost, environmentally friendly, and safe SNAC synthesis route with high process yield suitable for industrial production. SNAC demonstrates an absorption-enhancing effect on PK, and the optimal ratio of SNAC to PK is determined to be 32:1.

Development of functional consortia for the pretreatment of compostable lignocellulosic waste: A simple and effective solution to a large-scale problem

Microorganisms drive the degradation of organic matter thanks to their enzymatic versatility. However, the structure of lignocellulose poses a great challenge for the microbiota inhabiting a compost pile. Our purpose was to increase the biodegradability of vegetable waste in the early stages of the composting process by applying a microbial consortium with lignocelllulolytic capacity. For this, a previous screening was performed among the culturable microbiota from different composting processes to find inoculants with ligninocellulolytic activity. Selected strains were applied as a pure culture and as a microbial consortium. The starting material was composed of tomato plant and pruning remains mixed in a ratio (50:50 v/v), whose humidity was adjusted to around 65%. To determine the ability of both treatments to activate the biodegradation of the mixtures, moisture, organic matter, ash, C/N ratio, 4-day cumulative respirometric index (AT4) and degradation rates of cellulose, hemicellulose and lignin were evaluated. Subsequently, a real composting process was developed in which the performance of the microbial consortium was compared with the composting process without inoculum (control). According to our tests, three microbial strains (Bacillus safensis, Bacillus licheniformis and Fusarium oxysporum) were selected. The results showed that the application of the bacteria strains at low doses (104 CFU g−1 on the complete residual material of the pile) resulted in higher rates of lignocelullose degradation after 10 days of treatment compared to that observed after application of the fungus in pure culture or untreated controls. The implementation of the strategy described in this work resulted in obtaining compost with better agronomic quality than the uninoculated controls. Therefore, the application of this consortium could be considered as an interesting tool for bioactivation of lignocellulosic waste prior to the composting process.

Epidemiological, clinical, and geographical characterization of Leprosy in the County of Santarém-Pará: Insights for effective control and targeted intervention.

Leprosy is an infectious disease characterized by slow and chronic evolution, caused by Mycobacterium leprae and or Mycobacterium lepromatosis, an intracellular alcohol-acid-resistant (BAAR) bacillus. The objective of this study was to provide an epidemiological, clinical, and geographic characterization of leprosy in the city of Santarém-Pará during the period 2011-2020. A cross-sectional, descriptive, and quantitative approach was used, employing maps and tables to illustrate clinical and epidemiological variables, including: sex, age, race, area of residence, operational classification, clinical form, number of skin lesions, number of affected nerves, and health units. During the analyzed period, 581 cases of leprosy were diagnosed, resulting in the following cumulative incidence rates: male (60%); age over 15 years (94%); urban area (73%); multibacillary (74%); borderline form (46%); skin lesions greater than 5 (34%); and no nerves affected (68%). In the urban perimeter, a higher cumulative incidence of cases was observed in the central area with 133 cases. However, the health unit reporting the largest number of cases belonged to the southern area, specifically the Basic Health Unit of Nova República, with 48 cases. This study highlights the need to characterize the nuances of leprosy and its variability within the urban environment, according to different areas. Further research is essential to inform the implementation of public policies aimed at addressing the population with the highest vulnerability index, thereby reducing leprosy rates in Santarém.

Later aorta operation after aortic valve replacement for bicuspid aortic valve

BackgroundWe investigated long-term outcomes, particularly later aorta operations and overall death in patients who underwent aortic valve replacement for bicuspid aortic valve without aortic surgery.MethodsBetween January 2002 and December 2022, 274 patients underwent aortic valve replacement for bicuspid aortic valve at our institution. Of them, 181 patients who did not undergo aortic surgery, in accordance with current guidelines, were analyzed retrospectively.ResultsThe median follow-up duration was 6.1 (2.0–10.6) years, and follow-up was completed in 97.8% of pateints. There were 3 patients (1.7%) who underwent later aorta operation during follow-up period. The cumulative later aorta operation rate at 10 years adjusting overall death as competing risk was 16.3%, and the estimated rates of freedom from overall death at 10 years was 83.7%. Fine-Gray competing risk regression model showed that aortic valve stenosis was only the predictor of later aorta operation (hazard ratio 8.477; p = 0.012). In multivariable Cox models, predictors of overall death were aortic valve stenosis (hazard ratio: 8.270, 95% confidence interval: 1.082–63.235; p = 0.042) and operation time (hazard ratio: 1.011, 95% confidence interval: 1.004–1.017; p = 0.002).ConclusionsPatients with bicuspid aortic valve with ascending aortic diameter less than 45 mm are at low risk of later aorta operation after isolated aortic valve replacement.

Characteristics of Dry and Wet Changes and Future Trends in the Tarim River Basin Based on the Standardized Precipitation Evapotranspiration Index

Global changes in drought and wetness and their future trends in arid regions have recently become a major focus of research attention. The Tarim River Basin (TRB) in Xinjiang, China, is among the most climate-sensitive regions in the world. This study uses data from the past 60 years (1962–2021) to analyze the spatial and temporal features of drought and wetness conditions in the TRB, calculating the Standardized Precipitation Evapotranspiration Index (SPEI). Trend detection for SPEI is performed using the BEAST mutation test, identification of drought events using the theory of operations, and spatial and temporal analyses of dry and wet changes using Empirical Orthogonal Function (EOF) decomposition. Additionally, the CMIP6 dataset is used to estimate future changes. The study results indicate the following: (1) From 1962 to 1998, the TRB exhibited a “warm and wet” trend that suddenly shifted from “wet-to-dry” in 1998 and subsequently transitioned to a pronounced “warm and dry” trend. (2) After the “wet-to-dry” shift, the frequency of drought events noticeably increased. The northern section of the basin witnessed more frequent drought events, albeit with lower severity, while the southern part had fewer occurrences but with higher severity. The spatial distribution of drought event frequency and severity is inconsistent. (3) The EOF decomposition results for SPEI-variable fields at 1-, 3-, and 6-month time scales show that the cumulative variance contribution rate of the first three principal spatial modal feature vectors exceeds 70%. The spatial distribution of the modes includes a consistent pattern across the entire basin, a north–south opposite pattern, and an east–west opposite pattern. (4) The future trend of drought in the TRB is expected to intensify, manifesting a spatial pattern characterized by dryness in the middle of the basin and wetness around the periphery. These research findings can provide support for decisions addressing regional drought risks.

Predicting responses to omalizumab in antihistamine-refractory chronic urticaria: A real-world longitudinal study

BackgroundTreating chronic urticaria (CU) unresponsive to H1-antihistamines (H1AHs) is challenging, and the real-world effectiveness of omalizumab remains unclear. ObjectiveTo evaluate the real-world effectiveness of omalizumab, optimal response assessment timing, and predictive factors. MethodsInitially, 5,535 CU patients on ≥ 20 mg loratadine daily for ≥ 6 months (Jan 2007-Aug 2021) were screened; 386 patients receiving ≥ 6 months of omalizumab add-on treatment and were assessed for > 2 years. Predictors of treatment responses to omalizumab add-on therapy for anti-histamine refractory CU patients were identified using a generalized linear model. ResultsIn our retrospective cohort, omalizumab treatment showed cumulative response rates of 55.2% at 3 months, 71.0% at 6 months, and 81.4% at 9 months for H1AH-refractory CU patients. Longitudinal responses to omalizumab treatment revealed three distinct clusters: favorable (cluster 1, n=158), intermediate (cluster 2, n=143), and poor responses (cluster 3, n= 85). Subjects were categorized based on achieving a complete response within 3 months, identifying 213 early responders, 117 late responders, and 56 nonresponders. The initial dose of omalizumab differed significantly among the three clusters. Low total IgE (<40 kU/L) predicted non-response (OR=3.10, P=0.018). Early responders were associated with a higher initial omalizumab dose (≥300 mg, OR=2.07, P=0.016), higher basophil counts (OR=2.0, P=0.014), total IgE levels exceeding 798 kU/L (OR=0.37, P=0.047), and lower platelet-to-lymphocyte ratio (OR=0.50, P=0.050). ConclusionReal-world data reveal three distinct clusters for omalizumab treatment responses, confirm low serum total IgE (<40 kU/L) as a predictor of nonresponse, and identify potential biomarkers, including IgE, basophils, and PLR for early responders.

Comparison of pregnancy outcomes in women with normal ovarian response to the gonadotropin-releasing hormone agonist protocol using different trigger methods: a single-center retrospective cohort study based on propensity score matching.

To investigate whether gonadotropin-releasing hormone agonist (GnRH-a) combined with human chorionic gonadotropin (HCG) can improve pregnancy outcomes in patients with normal ovarian response (NOR). In this retrospective cohort study, data of 404 NOR patients undergoing fresh embryo transfer (ET) from 2018 to 2022 were studied. Patients were divided into HCG group and HCG plus GnRH-a group according to trigger methods. After confounding factors were controlled by propensity score matching, 67 cases were included in HCG group and HCG plus GnRH-a group, respectively, and pregnancy outcomes were assessed. Basal data, ovarian stimulation, embryological data and pregnancy outcomes were compared. The effect of trigger methods on pregnancy outcomes was analyzed by binary logistic regression. There was no statistically significant differences in embryological data, embryo implantation rate, clinical pregnancy rate, live birth rate of ET, number of fresh embryos transferred and total number of embryos transferred after one cycle of oocyte retrieval. While, cumulative live birth rate (CLBR) was better in the dual-trigger group than in the HCG group. The binary logistic regression analysis indicated that the trigger methods had an independent influence on embryo implantation and cumulative live birth. During IVF/ICSI, dual-trigger could potentially play a role in improving oocyte quality, ensuring embryo implantation rate, clinical pregnancy rate, live birth rate of ET and cumulative live birth rate at the end of one ovum pick-up (OPU) cycle, and reducing the physical, temporal and financial negative consequences due to repeated OPU cycle.

One-stage versus two-stage endoscopic management for acute cholangitis caused by common bile duct stones: A retrospective multicenter cohort study.

One-stage endoscopic management, where papillary interventions and stone removal are simultaneously performed, has been reported to be an effective treatment for acute cholangitis caused by common bile duct stones (CBDS). However, there have been few reports comparing it with two-stage management, and there is no established strategy for the indication of one-stage management. The aim of the present study was to compare the short- and long-term outcomes between one- and two-stage management for acute cholangitis caused by CBDS. We retrospectively studied 577 patients who underwent one- or two-stage endoscopic management for acute cholangitis between May 2010 and December 2020. The patients were divided into one- and two-stage groups by endoscopic management. The clinical outcomes were compared between groups. The technical and clinical success were similar in both groups, although the length of hospital stay was significantly shorter in the one-stage group. Although there was no difference in the early adverse event (AE) between two groups, post-ERCP pancreatitis was recognized in 3.4% and 10.0%, which was significantly higher in the two-stage group. The cumulative late AE rate was 22.6% and 14.1%, which was significantly higher in the one-stage group. In the multivariate analyses, intervention (one-stage), number of CBDS ≥2, biliary drainage, the use of ML, and gallbladder stone were identified as significant factors associated with the recurrence of CBDS. Although one-stage endoscopic management is useful and safe with reducing hospital stays, diligent postoperative follow-up with consideration to recurrence of CBDS is essential.

Association between body mass index and in vitro fertilization/intra-cytoplasmic sperm injection outcomes: An analysis of 15,124 normal ovarian responders in China.

High body mass index (BMI) results in decreased fecundity, and women with high BMI have reduced rates of clinical pregnancy and live birth in in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI). Meanwhile, ovarian responses show great heterogeneity in patients with a high BMI. This study aimed to analyze the effects of a high BMI on IVF/ICSI outcomes in the Chinese female with normal ovarian response. We performed a retrospective cohort study comprising 15,124 patients from the medical record system of the Reproductive Center of Peking University Third Hospital, with 3530 (23.3%) in the overweight group and 1380 (9.1%) in the obese group, who had a normal ovarian response (5-15 oocytes retrieved) and underwent fresh embryo transfer (ET) cycles from January 2017 to December 2018, followed by linked frozen-thawed embryo transfer (FET) cycles from January 2017 to December 2020. Cumulative live birth rate (CLBR) was used as the primary outcome. Furthermore, a generalized additive model was applied to visually illustrate the curvilinear relationship between BMI and the outcomes. We used a decision tree to identify the specific population where high BMI had the greatest effect on IVF/ICSI outcomes. High BMI was associated with poor IVF/ICSI outcomes, both in cumulative cycles and in separate fresh ET or FET cycles. In cumulative cycles, compared with the normal weight group, obesity was correlated with a lower positive pregnancy test rate (adjusted odds ratio [aOR]: 0.809, 95% confidence interval [CI]: 0.682-0.960), lower clinical pregnancy rate (aOR: 0.766, 95% CI: 0.646-0.907), lower live birth rate (aOR: 0.706, 95% CI: 0.595-0.838), higher cesarean section rate (aOR: 2.066, 95% CI: 1.533-2.785), and higher rate of large for gestational age (aOR: 2.273, 95% CI: 1.547-3.341). In the generalized additive model, we found that CLBR declined with increasing BMI, with 24kg/m 2 as an inflection point. In the decision tree, BMI only made a difference in the population aged ≤34.5years, with anti-Mullerian hormone >1.395ng/mL, and the first time for IVF. High BMI was related to poor IVF/ICSI outcomes in women with a normal ovarian response, and CLBR declined with increasing BMI, partly due to suppressed endometrial receptivity. A high BMI had the most negative effect on young women with anticipated positive prognoses.

Factors influencing rapid antiretroviral therapy initiation in Jiulongpo, Chongqing, China: a retrospective cohort from 2018 to 2022

BackgroundAntiretroviral Therapy (ART) is pivotal in extending the lives of people living with HIV (PLWH) and minimizing transmission. Rapid ART initiation, defined as commencing ART within seven days of HIV diagnosis, is recommended for all PLWH.MethodA retrospective cohort study was conducted using data from the China Information System for Disease Control and Prevention. This study included PLWH diagnosed between January 2018 and December 2021 and treated by December 2022. Factors influencing rapid ART initiation were examined using univariate and multivariate Cox regression analyses.ResultsThe study analyzed 1310 cases. The majority were male (77.4%), over 50 years old (46.7%), and contracted HIV through heterosexual transmission (70.0%). Rapid ART initiation was observed in 36.6% (n = 479) of cases, with a cumulative treatment rate of 72.9% within 30 days post-diagnosis. Heterosexual contact was associated with longer intervals from diagnosis to treatment initiation compared to homosexual contact (Adjusted Hazard Ratio (HR) = 0.813, 95% Confidence Interval (CI): 0.668–0.988). Individuals older than 50 years (Adjusted HR = 1.852, 95%CI: 1.149–2.985) were more likely to initiate ART rapidly. Conversely, treatment at the Second Public Hospital (Adjusted HR = 0.483, 95% CI: 0.330–0.708) and a CD4 cell counts above 500 (Adjusted HR = 0.553, 95% CI: 0.332–0.921) were associated with a lower likelihood of initiating treatment within seven days.ConclusionsA higher CD4 cell counts and receiving care in local public hospitals may deter rapid ART initiation. Providing CD4 counts results at diagnosis and offering testing and treatment in the same facility could enhance the rate of rapid ART initiation.

One-Year Outcome of Drug-Coated Balloon vs. Drug-Eluting Stent in Patients Undergoing Initial Percutaneous Coronary Intervention (PCI) for De Novo Lesion.

Drug-eluting stents (DES) are the major treatment option in percutaneous coronary intervention (PCI). Recently, drug-coated balloon (DCB) utilization has been increasing globally, leading to the expected new strategy of "stent-less PCI." This study aimed to evaluate the one-year outcome of DCB compared to DES. Patients who underwent initial PCI for de novo lesions in our institution from January 2018 to December 2021 (n=337) were subjected to retrospective analysis. Among them, 75 patients were treated with DCB, while 262 patients were treated with DES. Target lesion failure (TLF) was evaluated during the follow-up period. The proportion of PCIs for ACS was significantly lower in the DCB group (DCB, n=23, 30.7% vs. DES, n=143, 54.6%; p=0.001). The median device diameter and length in the DES group were larger than those in the DCB group (DCB, 2.60 mm vs. DES, 2.98 mm; p<0.001; DCB, 19.1 mm vs. DES, 25.2 mm; p<0.001). There was no significant difference between the DCB and DES groups in lesion calcification. The proportion of ostial lesions was significantly higher in the DCB group (DCB, n=13, 17.3% vs. DES, n=21, 8.0%; p=0.018). The cumulative rate of TLF (DCB, n=5, 6.7% vs. DES, n=18, 6.9%; p=0.951) did not significantly differ between the DCB and DES groups. DCB may be as effective a strategy as DES in the patient who underwent initial PCI for a de novo lesion.

The low-cycle fatigue behavior and an entropy-based life prediction model for Nickel-based single crystal superalloy across an extensive temperature range

Nickel-based single-crystal superalloys (Ni-SX) are prominently utilized in the fabrication of turbine blade materials for advanced aero-engines, owing to their commendable material characteristics. This paper delves into the low cycle fatigue (LCF) characteristics of a second-generation Nickel-based single-crystal superalloy across a temperature spectrum ranging from room temperature to 1000 °C. During this procedure, there is an escalation in the trend towards deformation homogenization, leading to a transition in fracture mode from shear fracture to normal fracture. A novel approach is introduced in the form of an entropy-based fatigue life prediction model, grounded in the correlation between cumulative plastic strain and entropy increase rate. Through a comparative examination with experimental data, the model demonstrates proficiency in precisely forecasting the fatigue life of Ni-SX under diverse strain amplitudes and temperature conditions.

Time-Lapse Incubation for Embryo Culture-Morphokinetics and Environmental Stability May Not Be Enough: Results from a Pilot Randomized Controlled Trial.

Background: Does the Time-lapse Incubator (TLI) add value to reproductive outcomes when its two components, undisturbed culturing and morphokinetic embryo grading, are separated. Methods: A prospective pilot, randomized, controlled, double-blinded, single-center study was conducted during the years 2016-2020. In total, 102 patients were randomized into three groups: (1) conventional incubation with morphological evaluation only (n = 34), (2) TLI with both morphological and morphokinetic evaluations (n = 32), and (3) TLI with morphological evaluation only (n = 36). All arms were cultured in ESCO-MIRI® incubators. A total of 1061 injected mature oocytes were evaluated (420 in arm 1, 285 in arm 2, and 356 in arm 3). The primary outcome was live birth rates. Secondary outcomes included clinical and cumulative pregnancy rates as well as embryo quality. Embryos in arm 3 were retrospectively evaluated for their morphokinetic score. Results: No significant difference was found in the live birth rate for single embryo transfer cycles (SET) (35% vs. 31.6% vs. 24%, p = 0.708) or double embryo transfer (DET) cycles (41.7% vs. 38.5% vs. 36.4%, p = 0.966). Comparable pregnancy rates, clinical pregnancy rates, and cumulative pregnancy were found for similar top-quality embryos for days 2, 3, and blastocyst stages across groups. A similar number of embryos were suitable for either transfer or cryopreservation within the different groups. For 62.8% of the embryos in arm 3, the morphokinetic and morphologic evaluations were similar. In only 2/36 (5.6%) treatment cycles, the use of morphokinetic scoring may have helped the patient avoid undergoing an additional treatment cycle. In the other cases, morphokinetic scoring would not have changed the end point of pregnancy. Conclusions: The two components of the TLI system-undisturbed culturing and morphokinetic embryo grading-do not appear to have a significant additional value in reproductive outcome, although these results should be validated by an RCT.

Study on the effect of stress path on the deformation and non-coaxial characteristics of modified iron tailings

In order to study the deformation and non-coaxial characteristics of fiber cement modified iron tailing sand (FCIT) under different stress paths. The evolution law of the dynamic stress ratio (η) on the cumulative deformation and non-coaxial angle of FCIT under different tension-compression amplitude ratios (α) was explored through hollow torsional shear tests. The deformation behavior of FCIT is analyzed by using the stability theory. The research results show that: 1) The increase of dynamic stress level will deepen the cumulative deformation of FCIT, while the increase of α will make the deformation mode of FCIT develop into bulging failure-shear failure-tensile failure. 2) According to the development trend of cumulative strain and cumulative strain rate of FCIT, it can be divided into three stages: plastic stability, plastic creep and incremental collapse, and the cumulative strain rate development prediction model is established, and the prediction error distribution is within ±20%. 3) The stress path determines the non-coaxiality of FCIT to a certain extent, and the non-coaxial angle fluctuates and decreases with the increase of the principal stress direction angle. When α=0.125, the maximum and minimum values of the non-coaxial angle of FCIT are 1.5 rad and 0.4 rad respectively. 4) Cement hydration reaction generates calcium alumina and hydrated calcium silicate (C-S-H) to make FCIT structure more compact, fiber-matrix interfacial connections more dense, and play a role in filling the pores.

Innovative approach for semi‐continuous production of puerarin palmitate via transesterification with novel immobilized lipase

BackgroundPuerarin, a flavonoid abundantly found in the roots of Pueraria lobata, exhibits antioxidant, anti-cancer, anti-inflammatory, and anti-aging properties. Despite its numerous benefits, the low bioavailability of puerarin hinders its widespread industrial application. To improve this, flavonoid acylation is required. Lipase is a biocatalyst primarily used for flavonoid acylation; immobilized lipase is preferred given the limited stability of free lipase. Although research on flavonoid acylation for structural modification is actively being conducted, there is a need to explore continuous production for enhancing the industrial application of flavonoid esters. Therefore, in this study, we aimed to produce puerarin palmitate innovatively by selecting an effective lipase, developing an immobilized lipase, characterizing the enzymatic reaction, and designing a semi-continuous reactor system.ResultsLipase from Thermomyces lanuginosus (TL) was found to be the most suitable for the synthesis of puerarin palmitate; it was successfully immobilized on glutaraldehyde-activated silica gel (GASG). TL GASG showed greater solvent, thermal, and operational stability than those of commercial immobilized lipases. Furthermore, TL GASG use resulted in a puerarin palmitate conversion rate of 97.17% within 3 h. Additionally, the reusability of TL GASG for this reaction was higher than that of commercially available immobilized lipases. Upon using a semi-continuous reactor, the cumulative conversion rate of puerarin palmitate remained above 85% after more than ten substrate injections.ConclusionsThe results support the feasibility of the continuous production of flavonoid esters, underscoring their diverse industrial applications. A biorefinery strategy is anticipated to be proposed to utilize P. lobata extract biomass for flavonoid ester production. Moreover, optimizing continuous reactors through statistical experimental design is expected to enhance flavonoid ester production efficiency; these aspects will be explored in future research.Graphical

The effect of health literacy on early postoperative recovery of patients undergoing outpatient surgery.

The measurement of the health literacy level of patients undergoing outpatient surgery has become a major challenge in perioperative nursing of outpatient surgery. To analyze the effect of health literacy on early postoperative recovery of patients undergoing outpatient surgery by developing a health literacy assessment tool for this population. A scale for the assessment of health literacy was established based on Nutbeam's health literacy model. From April to September 2021, 264 patients were selected in the daytime operating rooms of six Class A tertiary hospitals in Kunming, Yunnan Province to investigate health literacy and early postoperative rehabilitation quality, and the influencing factors of the two variables were analyzed. An assessment scale of health literacy of patients undergoing outpatient surgery was developed, including 3 dimensions and 24 items. The Cronbach's α coefficient of the total scale was 0.944, the split-half reliability was 0.902, and the content validity was 0.920. Exploratory factor analysis showed that the cumulative variance contribution rate was 66.37%, and the scale had good structural validity. Multiple linear regression analysis showed that age, functional health literacy, interactive health literacy, and critical health literacy could explain 60.4% of the variation (adjusted R2= 0.583) of postoperative recovery quality of patients undergoing outpatient surgery. Health literacy of patients undergoing outpatient surgery is an important factor that affects the quality of early postoperative recovery. The health literacy assessment scale can assist medical staff in implementing personalized perioperative nursing and health education.

The Absorb GT1 Bioresorbable Vascular Scaffold System - 5-Year Post-Market Surveillance Study in Japan.

The 1-year clinical outcomes of the Absorb GT1 Japan post-market surveillance (PMS) suggested that an appropriate intracoronary imaging-guided bioresorbable vascular scaffold (BVS) implantation technique may reduce the risk of target lesion failure (TLF) and scaffold thrombosis (ST) associated with the Absorb GT1 BVS. The long-term outcomes through 5 years are now available.Methods and Results: This study enrolled 135 consecutive patients (n=139 lesions) with ischemic heart disease in whom percutaneous coronary intervention (PCI) with the Absorb GT1 BVS was attempted. Adequate lesion preparation, imaging-guided appropriate sizing, and high-pressure post-dilatation using a non-compliant balloon were strongly encouraged. All patients had at least 1 Absorb GT1 successfully implanted at the index procedure. Intracoronary imaging was performed in all patients (optical coherence tomography: 127/139 [91.4%] lesions) and adherence to the implantation technique recommendations was excellent: predilatation, 100% (139/139) lesions; post-dilatation, 98.6% (137/139) lesions; mean (±SD) post-dilatation pressure, 18.8±3.5 atm. At 5 years, the follow-up rate was 87.4% (118/135). No definite/probable ST was reported through 5 years. The cumulative TLF rate was 5.1% (6/118), including 2 cardiac deaths, 1 target vessel-attributable myocardial infarction, and 3 ischemia-driven target lesion revascularizations. Appropriate intracoronary imaging-guided BVS implantation, including the proactive use of pre- and post-balloon dilatation during implantation may be beneficial, reducing the risk of TLF and ST through 5 years.

Respiratory morbidity among offspring misclassified as growth restricted.

An ultrasound-based diagnosis implies that some fetuses suspected to be growth-restricted (FGR) are discovered at birth to be appropriately grown (appropriate for gestational age [AGA] birth weight, between the 10th and 90th percentile). These fetuses may thus be exposed to unnecessary medical interventions, including early labor induction. In this study, we have evaluated the long-term respiratory health of offspring misclassified as FGR. A population-based cohort analysis was conducted, including deliveries of AGA singletons between 1991 and 2021 at a tertiary referral hospital. Incidence of morbidity due to various respiratory conditions was compared between AGA offspring with prenatal diagnosis of FGR, and those without a false diagnosis of FGR. The Kaplan-Meier approach was used to estimate cumulative morbidity incidence. The stratified Cox proportional-hazards model was used to control for confounders. A total of 324,620 deliveries of AGA newborns were included in the analyses; 3249 of them (1.0%) were misclassified prenatally as FGR. The FGR subgroup delivered at an earlier gestational age (36.7 vs. 39.1 weeks, p < .001) and had more than 25% higher incidence of respiratory-related morbidity during childhood (33.2% vs. 26.5%), specifically related to asthma and obstructive sleep apnea (p < .001 for all). A higher cumulative morbidity rate due to respiratory conditions was observed in the Kaplan-Meier survival curve (log-rank p value < .001). This association between FGR and respiratory morbidity was independent of preterm delivery, maternal age, cesarean delivery, and child's birth year (adjusted hazard ratio = 1.14, 95% confidence interval: 1.07-1.21, p < .001), using a Cox proportional hazards model. AGA newborns misclassified as FGR, are at an increased risk for long-term respiratory morbidity during childhood and adolescence.

Worsening of health disparities across COVID-19 pandemic stages in Korea.

With the end of the coronavirus disease 2019 (COVID-19) pandemic, the health outcomes of this disease in Korea must be examined. We aimed to investigate health outcomes and disparities linked to socioeconomic status during the COVID-19 pandemic in Korea and to identify risk factors for hospitalization and mortality. This nationwide retrospective study incorporated an analysis of individuals with and without COVID-19 in Korea between January 1, 2020, and December 31, 2022. The study period was divided into 4 stages. Prevalence, hospitalization, mortality, and case-fatality rates were calculated per 100,000 population. Multivariate logistic regression was performed to identify risk factors for COVID-19 hospitalization and mortality. Overall, the incidence rate was 40,601 per 100,000 population, the mortality rate was 105 per 100,000 population, and the case-fatality rate was 259 per 100,000 cases. A total of 12,577,367 new cases (24.5%) were recorded in stage 3 and 8,979,635 cases (17.5%) in stage 4. Medical Aid recipients displayed the lowest 3-year cumulative incidence rate (32,737 per 100,000) but the highest hospitalization (5,663 cases per 100,000), mortality (498 per 100,000), and case-fatality (1521 per 100,000) rates. Male sex, older age, lower economic status, non-metropolitan area of residence, high Charlson comorbidity index, and disability were associated with higher risk of hospitalization and death. Vaccination was found to reduce mortality risk. As the pandemic progressed, surges were observed in incidence, hospitalization, and mortality, exacerbating disparities associated with economic status and disability. Nevertheless, Korea has maintained a low case-fatality rate across all economic groups.
