Broth microdilution (BMD) is the gold standard but is impractical for routine application. Current automated AST systems improve efficiency but face accuracy or operational challenges, highlighting the need for reliable and user-friendly solutions.Objective: This study aims to evaluate the performance of a novel automated AST system (AutoMic-i600) based on the BMD method for AST of common clinical bacteria.Methods: A total of 229 clinical isolates (150 Gram-negative and 79 Gram-positive) were prospectively collected from microbiology laboratory between June 2023 and August 2023. We reported the comparison of the AutoMic-i600 and Vitek 2 systems for routine antibiotics, and also validated the detection performance of AutoMic-i600 for novel antibiotics, based on the BMD method.Results: The overall essential agreement (EA) and categorical agreement (CA) between AutoMic-i600 and BMD were 93.2% and 93.5% for Gram-negative bacteria and 98.5% and 97.8% for Gram-positive bacteria, respectively. The overall EA and CA between Vitek 2 and BMD were 92.6% and 93.5% for Gram-negative bacteria and 97.9% and 97.4% for Gram-positive bacteria. Importantly, for drug-resistant bacteria, AutoMic-i600 demonstrated a higher overall agreement than Vitek 2 (EA: 98.1% vs 94.8%, CA: 97.5% vs 92.0%), especially in Gram-negative bacteria (EA: 97.7% vs 93.5%, CA: 97.7% vs 89.3%). The VME rate for Gram-negative bacteria using AutoMic-i600 was significantly lower than that of Vitek 2 (1.0% vs 2.9%). Novel antibiotics detected by AutoMic-i600 exhibited EA and CA rates exceeding 90.0%.Conclusion: Based on these findings, we recommend that the AutoMic-i600 system could be a new option for routine AST testing in a clinical setting. Particularly for drug-resistant bacteria and novel antibiotics, detection with AutoMic-i600 may be more reliable, which could further contribute to the prevention and treatment of drug-resistant bacteria.Keywords: antibiotic susceptibility testing, drug-resistant bacteria, AutoMic-i600 system, automate

Among various therapeutic strategies, apoptotic extracellular vesicles (ApoEVs) have emerged as promising agents in tissue regeneration. Specifically, T cell-derived ApoEVs have shown substantial potential in facilitating bone regeneration. However, it remains unclear whether ApoEVs can promote bone mass recovery through enzymatic activity mediated by membrane surface molecules. Therefore, this study aimed to investigate whether T cell-derived ApoEVs could promote bone mass recovery in osteoporosis mice and reveal the underlying mechanisms.Methods: ApoEVs were isolated through sequential centrifugation, and their proteomic profiles were identified via mass spectrometry. Western blot and immunogold staining confirmed the enrichment of CD39 and CD73 on ApoEVs. The role of CD39 and CD73 in hydrolyzing adenosine triphosphate (ATP) to adenosine was evaluated by quantifying the levels of ATP and adenosine. Inhibitors of CD39 and CD73, and an A2BR antagonist were used to explore the molecular mechanism of ApoEVs in promoting bone regeneration.Results: ApoEVs significantly reduced bone loss and promote the osteogenic differentiation of BMMSCs in ovariectomy (OVX) mice. We observed increased levels of extracellular ATP and a decrease in CD39 and CD73, key enzymes in ATP-to-adenosine conversion in bone marrow of OVX mice. We found that ApoEVs are enriched with CD39 and CD73 on their membranes, which enable the hydrolysis of extracellular ATP to adenosine both in vitro and in vivo. The adenosine generated by ApoEVs inhibits the inflammatory response and promotes osteogenesis through A2BR and downstream PKA signaling.Conclusion: T cell-derived ApoEVs are enriched with CD39 and CD73, enabling them to hydrolyze extracellular ATP to adenosine, thereby promoting bone regeneration via A2BR and PKA signaling pathway. Our data underscore the substantive role of T cell-derived ApoEVs to treat osteoporosis, thus providing new ideas for the development of ApoEVs-based therapies in tissue regeneration.

However, the possibilities of recurrent rupture and nerve complications remain. Hence, the present study was conducted to describe a modified repair technique for the Achilles tendon able to overcome these limitations.Patients and Methods: This retrospective study included 36 patients with acute closed Achilles tendon rupture treated at our institution between January 2020 and January 2022. All patients underwent surgery at our institution and were followed up for 12– 25 months. Functional evaluation was based on the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale and the Achilles tendon total rupture score (ATRS), along with local complications.Results: None of the patients had sural nerve injury, infection or re-rupture at a minimum follow up of 12 months. At the final follow-up, the average AOFAS ankle-hindfoot score and ATRS were 95.5 and 90.0, respectively. The final magnetic resonance imaging showed continuity and thicker regeneration of the tendon.Conclusion: The modified percutaneous repair of the Achilles tendon is an effective procedure which yields good functional outcome with few complications, and it could be widely promoted in clinical practice.Keywords: Achilles tendon, acute rupture, percutaneous repair, minimally invasive technique, clinical outcome

This study seeks to elucidate the interconnections between these three elements.Methods: The study used 2020 CHARLS data for analysis. To assess the intricate association among sleep time, body pain, and depressive symptoms, the study employed Spearman correlation analysis, multiple logistic regression, restricted cubic splines, and mediation effect analysis based on bootstrap testing.Results: Risk factors for depressive symptoms in middle-aged and elderly Chinese include physical pain and reduced sleep duration. Results from the RCS suggest that the lowest risk of depressive symptoms occurs when the sleep time for the middle-aged and elderly population is approximately 7.5 hours. Body pain accounts for a 19.05% mediating effect between sleep time and depressive symptoms, and even after controlling confounding factors, there remains a 7.5% mediating effect.Conclusion: The research findings indicate that there is a significant correlation among sleep time, body pain, and depressive symptoms. Insufficient sleep time and body pain can lead to depressive symptoms. Body pain plays a partial mediating role between sleep time and depressive symptoms.Keywords: middle-aged and elderly people, sleep time, body pain, depressive symptoms

We used the Athens Insomnia Scale to assess sleep quality on postoperative day (POD) 1 and POD 3 and analyzed the correlation between intraoperative sleep spindle activity and PSD through logistic regression.Results: The incidence of PSD was 65.6% on POD 1 and 41.9% on POD 3. On the first day, there were no significant differences in intraoperative sleep spindle characteristics between PSD and non-postoperative sleep disturbance (non-PSD) patients. However, by the third day, PSD patients showed lower sigma power compared to non-PSD patients, as well as lower spindle density in the bilateral frontopolar (Fp1/Fp2) and bilateral temporal (F7/F8) channels, with shorter average spindle duration (P < 0.05). Multivariate logistic regression analysis suggested that the average spindle density in F7/F8 channels (OR 0.543, 95% CI 0.375– 0.786; P = 0.001) was an independent risk factor for PSD on POD 3. Furthermore, Mini-Mental State Examination (MMSE) could independently predict PSD on POD 1 (OR 0.806, 95% CI 0.656– 0.991; P = 0.041) and POD 3 (OR 0.701, 95% CI 0.562– 0.875; P = 0.002). Pain on movement and at rest were independently associated with PSD on POD 1 (OR 1.480, 95% CI 1.200– 1.824; P < 0.001) and POD 3 (OR 1.848, 95% CI 1.166– 2.927; P = 0.009), respectively.Conclusion: Intraoperative mean spindle density in the F7/F8 channels was an independent risk factor for PSD on POD 3 in elderly patients undergoing orthopedic surgery. MMSE and postoperative pain also independently increased the risk of PSD.Keywords: postoperative sleep disturbance, sleep spindle, electroencephalography spectrum, elderly patients, orthopedic surgery

Group E received ESPB before induction, followed by continuous ESPB analgesia, while Group P received postoperative intravenous controlled analgesia. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used to assess postoperative sleep disturbance (PSD) on the postoperative day 3 (POD3). The St. Mary’s Hospital Sleep Questionnaire (SMH) evaluated sleep quality on the day of surgery and postoperative day 1 (POD1) and postoperative day 2 (POD2). The Identity Consequence Fatigue Scale-10 (ICFS-10) was utilized to evaluate postoperative fatigue status. Numeric Rating Scale (NRS) scores at resting and coughing were recorded at extubation, 6 h, 24 h, 48 h, 72 h after surgery. Consumption of propofol, remifentanil, and remedial analgesics (bucinazine), hospital duration, occurrence of postoperative adverse reactions were documented. Interleukin-6 (IL-6) and interleukin-10 (IL-10) serum levels were measured before surgery, 12 h, 24 h, 48 h after surgery.Results: The incidence of PSD in group E on POD3 was significantly lower than group P (75% vs 25%). Patients in group E had higher SMH scores than group P on the day of surgery and POD2. Compared with group P, the NRS scores of resting and coughing at all time points, remifentanil and bucinazine consumption, postoperative ICFS-10 scores, the incidence of nausea and vomiting, IL-6 serum levels in group E were significantly decreased. The IL-10 serum levels in group E were significantly higher than those in group P.Conclusion: The continuous ESPB can improve postoperative sleep quality, alleviate pain, fatigue and inflammation, and reduce the incidence of postoperative nausea and vomiting.Keywords: continuous erector spinae plane block, thoracoscopic, lung lobe resection, postoperative sleep disturbance

Nonetheless, the function of TRPC5 in OSA-induced cardiac injury remains uncertain. For this research, we aimed to explore the role and potential mechanism of TRPC5 in cardiomyocyte injury induced by intermittent hypoxia.Methods: 30 patients with newly diagnosed OSA and 30 patients with primary snoring(PS) were included in this study. Participants were subjected to polysomnography (PSG) for OSA diagnosis. Echocardiography was used to evaluate the structure and function of the heart, while peripheral blood samples were obtained. Additionally, RT-qPCR was utilized to quantify the relative expression level of TRPC5 mRNA in peripheral blood. H9c2 cells experienced IH or normoxia. TRPC5 levels in H9c2 cells were determined via RT-qPCR and Western blotting (WB) methods. H9c2 cells overexpressing TRPC5 were subjected to either normoxic or intermittent hypoxia conditions. Cell viability was determined by CCK8, the apoptosis rate, reactive oxygen species(ROS) levels, and Ca2+ concentration were assessed by flow cytometry, and the protein levels of TRPC5, Bcl-2, Bax, and Caspase-3 were analyzed by WB. Mitochondrial membrane potential(MMP), mitochondrial membrane permeability transition pore(mPTP), and transmission electron microscopy(TEM) were employed to observe mitochondrial function and structure. After inhibiting ROS with N-acetylcysteine (NAC), apoptosis, mitochondrial function and structure, and the concentration of Ca2+ were further detected.Results: TRPC5 and left atrial diameter (LAD) were higher in OSA individuals, while the E/A ratio was lower(all P< 0.05). IH impaired cell viability, triggered cell apoptosis, and enhanced TRPC5 expression in H9c2 cells(all P< 0.05). The effects of IH on apoptosis, cell viability, mitochondrial function and structure damage, and oxidative stress (OxS) in H9c2 cells were accelerated by the overexpression of TRPC5(all P< 0.05). Furthermore, cell apoptosis and mitochondrial structural and functional damage caused by overexpression of TRPC5 were attenuated by ROS inhibition.Conclusion: TRPC5 is associated with structural and functional cardiac damage in patients with OSA, and TRPC5 promotes IH-induced apoptosis and mitochondrial damage in cardiomyocytes through OxS. TRPC5 may be a novel target for the diagnosis and treatment of OSA-induced myocardial injury.Keywords: TRPC5, oxidative stress, apoptosis, intermittent hypoxia, OSA

However, better prediction tools for severe OSA applicable to patients with obesity have not been developed.Patients and Methods: Relevant clinical data of 1008 patients with OSA who underwent bariatric surgery in our hospital were collected retrospectively. Patients were divided into training and test cohorts by machine learning. Univariate and multivariate logistic regression analysis was used to screen associations, including liver stiff measurement (LSM) and abdominal visceral tissue (aVAT), and to construct a severe OSA risk prediction nomogram. Then, we evaluated the effectiveness of our model and compared our model with the traditional Epworth Sleepiness Scale (ESS) model. Finally, our associations were used to explore the correlation with other indicators of OSA severity.Results: Our study revealed that age, biological sex, BMI, LSM, aVAT, and LDL were independent risk factors for severe OSA in patients with obesity. A severe OSA risk prediction nomogram constructed by six indicators possessed high AUC (0.845), accuracy (77.6%), and relatively balanced specificity and sensitivity (72.4%, 82.8%). The Hosmer-Lemeshow test (P=0.296, 0.785), calibration curves, and DCA of the training and test cohorts suggested better calibration and more net clinical benefit. Compared with the traditional ESS model, our model had higher AUC (0.829 vs 0.545), sensitivity (78.9% vs 12.2%), PPV (77.9% vs 53.3%), and accuracy (75.4% vs 55.2%). In addition, the associations in our model were independently correlated with other indicators reflecting OSA severity.Conclusion: We provided a simple, cheap, and non-invasive nomogram of severe OSA risk prediction for patients with obesity, which would be helpful for preventing further complications associated with severe OSA.Plain Language Summary: Question: Can we predict severe OSA in patients with obesity by their metabolic complications through some non-invasive examinations?Findings: Compared with traditional questionnaires, we developed and validated a new prediction model, including liver stiffness measurement and abdominal visceral adipose tissue, to screen severe OSA in bariatric surgery candidates through non-invasive examinations, which may contribute to perioperative safety and ultimate weight loss outcomes.Meaning: For patients with obesity who are in hospital because of metabolic disorders, it is necessary for them to be screened for possible severe OSA according to our new prediction nomogram, which is helpful for preventing further complications and perioperative risk associated with severe OSA.Keywords: obstructive sleep apnea, obesity, liver stiffness measurement, visceral adipose tissue, nomogram

This study examines the predictive efficacy of the Advanced Lung Cancer Inflammation Index (ALI) in assessing the post-hepatectomy prognosis of patients with HCC.Methods: A cohort comprising 1654 HCC patients who underwent hepatectomy at Guangxi Medical University Cancer Hospital from 2013 to 2019 was enrolled. Patients were stratified into two groups according to the median ALI level, and then subjected to propensity score matching (PSM) in a 1:1 ratio. Kaplan-Meier survival curves, the traditional Cox proportional hazards (CPH) model, and machine learning (ML) models were employed to analyze and evaluate ALI’s prognostic significance. Furthermore, ALI’s prognostic value in digestive system tumors was validated via analysis of the National Health and Nutrition Examination Survey (NHANES) database.Results: After applying PSM, a final cohort of 1284 patients, categorized into high and low ALI groups, revealed a significantly reduced survival time in the low ALI cohort. Univariate and multivariate Cox analyses identified ALI, BCLC stage, CK19, Hepatitis B virus (HBV) DNA, lymph node metastasis, and microvascular invasion (MVI) as independent predictors of prognosis. Both traditional CPH and ML models incorporating ALI demonstrated excellent predictive accuracy, validated through calibration curves, time-dependent ROC curves, and decision curve analysis. Furthermore, the prognostic value of ALI in digestive tumors was confirmed in the NHANES database.Conclusion: The ALI exhibits potential as a prognostic predictor in patients with HCC following hepatectomy, providing valuable insights into postoperative survival.Keywords: advanced lung cancer inflammatory index, ALI, hepatocellular carcinoma, HCC, prognosis, Cox regression, machine learning, ML

Although there have been many reports of biological agents treating pityriasis rubra pilaris recently, the clinical application of the JAK inhibitors in the treatment of pityriasis rubra pilaris has been rarely reported, and there is a lack of evidence on the safety and efficacy of these drugs. We explore the use of the JAK inhibitor tofacitinib in the treatment of pityriasis rubra pilaris with significant efficacy and no significant side effects, providing new ideas for the clinical treatment of pityriasis rubra pilaris.Methods: We cover a case of pityriasis rubra pilaris treated with the JAK inhibitor tofacitinib, which showed significant efficacy without any adverse effects.Results: This case report showed that the JAK inhibitor tofacitinib had significant clinical efficacy in the treatment of pityriasis rubra pilaris. We speculated that the treatment of pityriasis rubra pilaris with the JAK inhibitors may be related to blocking the activation of the JAK/STAT pathway, thereby blocking the high expression of cytokines IL-17, IL-12/IL-23, IL-23, TNF-α.Conclusion: The JAK inhibitor tofacitinib can become a new option for treating pityriasis rubra pilaris.Keywords: pityriasis rubra pilaris, JAK inhibitors, tofacitinib, secukinumab, ustekinumab

The mechanism of IDD development and progression is not fully understood. Peripheral biomarkers are increasingly vital non-radioactive methods in early detection and diagnosis for IDD. Nevertheless, less attention has been paid to the role of mitophagy genes in the progress of IDD. This study aimed to identify the mitophagy disease-causing genes in the process of IDD and mitophagy diagnostic biomarkers for IDD.Methods: Mitophagy-related differentially expressed genes (MRDEGs) related to IDD were investigated by analyzing the microarray datasets of IDD cases from GEO, PathCards and Molecular Signatures Databases. We used R software, WGCNA, PPI, mRNA-miRNA, mRNA-TF, GO, KEGG, GSEA, GSVA and Cytoscape to analyze and visualize the data. We further used ssGSEA for immunoinfiltration analysis to obtain different immune cell infiltration. LASSO model was developed to screen for genes that met the diagnostic gene model requirements. Finally, qRT-PCR, Western blotting and HE were used to verify hub genes and their expression from clinical IDD samples.Results: We identified 14 MRDEGs and 12 hub genes. GO, KEGG, GSEA and GSVA analyses demonstrated that hub genes were critical for the development of IDD. LASSO diagnostic model consisted of six hub genes, among which SQSTM1, ATG7 and OPTN were significantly different between the two IDD disease subtypes. At the same time, SQSTM1 also had a high correlation with immune characteristic subtypes. The results of qRT-PCR and Western blotting also indicated that these genes were significantly differentially expressed in nucleus pulposus cells (NPCs) of the IDD group.Conclusion: We explored an association between MRDEGs-associated signature in IDD and validated that hub genes like SQSTM1 might serve as biomarkers for diagnostic and therapeutic targets for IDD. Meanwhile, this study can provide new insights into the functional characteristics and mechanism of mitophagy in the development of IDD.

Capsules are an important component of KP’s virulence, among which the K1, K2, K5, K20, K54, and K57 serotypes are predominant and exhibit varying degrees of virulence.Methods: The capsule and virulence genes of 150 carbapenem-resistant Klebsiella pneumoniae (CRKP) and 213 carbapenem-sensitive Klebsiella pneumoniae (CSKP) isolates were examined by polymerase chain reaction (PCR). The isolates were tested for hypermucoviscosity by string tests. Phylogenetic relationships between KP isolates were analyzed using multilocus sequence typing (MLST) and a Galleria mellonella infection model confirmed the differences in virulence.Results: A total of 111 of 363 isolates of KP were detected, the highest detected serotypes were K1, K5, and K2, and CSKP was detected more frequently than CRKP. There was a greater prevalence of K1 and K2 serotypes in CSKP, while in CRKP, K5 serotypes were more prevalent. K1 isolates had the highest detection rates for hypermucoviscosity Klebsiella pneumoniae (hmKP) and hypervirulent Klebsiella pneumoniae (hvKP), and carried the most virulence genes. K54 isolates had the lowest detection rate of hmKP while K5 isolates had the lowest detection rate of hvKP and carried the fewest virulence genes. MLST results for serotypes K1, K20, and K57 showed significant homogeneity, while those for serotypes K2, K5, and K54 showed diversity. The Galleria mellonella infection model showed that the K1 serotype was the most virulent and the K54 serotype was the weakest.Conclusion: CSKP isolates were detected more frequently than CRKP isolates for capsular serotype detection. K1 isolates had the most virulence gene and strongest virulence, K5 isolates carried the fewest virulence genes, and K54 isolates had the weakest virulence. Furthermore, significant homogeneity was observed among K1, K20, and K57 isolates.Keywords: Klebsiella pneumoniae, capsular serotypes, virulence, MLST

Cuproptosis is a form of cell death that is associated with a wide range of diseases. This study aimed to explore genes associated with cuproptosis in sepsis, construct predictive models and screen for potential targets.Methods: The LASSO algorithm and SVM-RFE model has been analysed the expression of cuproptosis-related genes in sepsis and immune infiltration characteristics and identified the marker genes under a diagnostic model. Gene-drug networks, mRNA-miRNA networks and PPI networks were constructed to screen for potential biological targets. The expression of marker genes was validated based on the GSE57065 dataset. Consensus clustering method was used to classify sepsis samples.Results: We found 381 genes associated with the development of sepsis and discovered significantly differentially expressed cuproptosis-related genes of 16 cell types in sepsis and immune infiltration with CD8/CD4 T cells being lower. NFE2L2, NLRP3, SLC31A1, DLD, DLAT, PDHB, MTF1, CDKN2A and DLST were identified as marker genes by the LASSO algorithm and the SVM-RFE model. AUC > 0.9 was constructed for PDHB and MTF1 alone respectively. The validation group data for PDHB (P=0.00099) and MTF1 (P=7.2e-14) were statistically significant. Consistent clustering analysis confirmed two subtypes. The C1 subtype may be more relevant to cellular metabolism and the C2 subtype has some relevance to immune molecules.The results of animal experiments showed that the gene expression was consistent with the bioinformatics analysis.Discussion: Our study systematically explored the relationship between sepsis and cuproptosis and constructed a diagnostic model. And, several cuproptosis-related genes may interfere with the progression of sepsis through immune cell infiltration.Keywords: machine learning, cuproptosis, immune infiltration, sepsis, diagnostic model

Accumulating evidence indicates that hypoxia and lactate metabolism play critical roles in tumor progression and therapeutic efficacy. This study aimed to construct a hypoxia- and lactate metabolism-related prognostic model (HLPM) to evaluate survival and treatment responses for HCC patients and develop a nomogram integrated with HLPM and clinical characteristics for prognosis prediction in HCC.Methods: Expression profile and clinical data of HCC were obtained from TCGA and ICGC databases. The univariate, LASSO and stepwise multivariate Cox analyses were used to identify the hypoxia- and lactate metabolism-related biomarkers, whose expression levels were then validated in 14 pairs tissue samples and single-cell RNA sequencing dataset. Kaplan–Meier survival curves were utilized to assess the prognostic values of biomarkers or models. Analyses of ImmuCellAI, TIDE and drug sensitivity were conducted to evaluate the therapeutic responses of patients. Furthermore, the nomogram integrated with hypoxic and lactate metabolic characteristics was established through univariate and multivariate Cox analyses. ROC curves, C-index, and calibration curves were depicted to evaluate the performance of the nomogram.Results: Five hypoxia- and lactate metabolism-related biomarkers (KIF20A, IRAK1, ADM, PPARGC1A and EPO) were used to construct HLPM. The expression of five prognostic biomarkers was validated in 14 pairs tissue samples and single-cell RNA sequencing dataset. Analyses of ImmuCellAI, TIDE and drug sensitivity implied that patients with low-risk score were more sensitive to immunotherapy and major chemotherapeutic agents. The nomogram that contained age, histological grade and risk score of HLPM was developed and exhibited a better capacity in prognosis prediction than HLPM only.Conclusion: A novel nomogram integrated with hypoxic and lactate metabolic characteristics was developed and validated for prognosis prediction in HCC, providing insight into personalized decision-making in clinical management.Keywords: hepatocellular carcinoma, nomogram, prognosis, lactate metabolism, hypoxia, immunotherapy

Experimental cross sections for the He4(e,e′p)X reactions in the missing energy range from 0.017 to 0.022 GeV and up to a missing momentum of 0.632 GeV/c at xB=1.24 and Q2=2 (GeV/c)2 are reported. The data are compared to relativistic distorted-wave impulse approximation calculations for the He4(e,e′p)H3 channel. Significantly more events are observed for pm≥0.45 GeV/c than are predicted by the theoretical model, and striking fluctuations in the ratio of data to the theoretical model around pm=0.3GeV/c are possible signals of initial-state multinucleon correlations.

However, the association between temperature changes and coronary artery disease (CAD) is not well documented. This study aimed to explore the association between daily mean temperature and daily CAD hospital admissions on the southeast coast of China (Fuzhou City).Methods: A total of 1883 CAD patients who underwent percutaneous coronary intervention between 2017 and 2019 were obtained. The severity of CAD was evaluated by the Gensini score. Distributed lag non-linear model (DLNM) combined with a quasi-Poisson regression model was used to examine the delayed effect between daily mean temperature and daily CAD hospital admissions. Stratified analyses were performed by Gensini score and severity of lesions. The relative risk (RR) with a 95% confidence interval (CI) was used to assess the relationship.Results: Extreme cold (8°C) (RR=0.49, 95% CI: 0.25– 0.99) and moderate cold (10°C) (RR=0.56, 95% CI: 0.31– 0.99) daily mean temperature with a lag of 0– 20 days were correlated with lower risk of daily CAD hospital admissions. Moderate heat (30°C) (RR=1.80, 95% CI: 1.01– 3.20) and extreme heat (32°C) (RR=2.02, 95% CI: 1.01– 4.04) daily mean temperature with a lag of 0– 20 days related to a higher risk of daily CAD hospital admissions. Similar results were observed for daily mean temperature with a lag of 0– 25 days. Stratified analysis showed the lagged effect of daily mean temperature (lag 0, 0– 5, 0– 15, 0– 20, and 0– 25 days) on the daily CAD hospital admissions was observed only in patients with a Gensini score ≤ 39 (tertile 1).Conclusion: Cold temperatures may have a protective effect on daily CAD hospital admissions in the Fuzhou area, whereas hot temperatures can have an adverse effect.Keywords: temperature, coronary artery disease, gensini score, daily admissions, lag effect

The transcripts of these interviews were transcribed into textual data, which was then subjected to Colaizzi’s seven-step analysis for meticulous coding and comprehensive thematic elucidation.Results: The comprehensive analysis of the factors involved in the intricate decision-making dilemmas faced by parents of children with severe asthma during the process of crafting discharge care plans in the PICU revealed five themes and eight sub-themes: 1) Complexity of asthma-related information; 2) Insufficient provision of comprehensive decision-making support; 3) Encountering negative emotions and wavering confidence; 4) Navigating realistic constraints impacting both parents and HCPs; 5) Balancing the advantages and disadvantages of various plans.Conclusion: Parents of children with severe asthma in the PICU encounter intricate and multifaceted decision-making dilemmas while engaging in the formulation of discharge care plans. These complexities significantly dampen their decision-making enthusiasm and introduce potential risks to the children’s prognosis and recovery. In the future, it is imperative to leverage the guidance provided by healthcare professionals (HCPs) in the decision-making process, develop tailored decision support tools specifically designed for the formulation of discharge care plans for children with severe asthma in the PICU.Keywords: severe asthma, parents, discharge care plan, decision-making dilemma, phenomenological study
