Objective:To evaluate the predictive value of the Controlling Nutritional Status (CONUT) score for severe acute pancreatitis (SAP).Methods:A total of 426 patients with acute pancreatitis (AP) admitted to the First Affiliated Hospital of Zhengzhou University between January and December 2024 were retrospectively reviewed. After applying exclusion criteria, 189 patients were included and classified into non-severe AP (NSAP) and SAP groups according to diagnostic criteria. Demographic characteristics (age, sex, underlying diseases), vital signs, CONUT score, Bedside Index for Severity in Acute Pancreatitis (BISAP) score, and laboratory parameters (including complete blood count, blood glucose, liver and kidney function, coagulation profile, amylase, and lipase) on admission were compared between the two groups. Binary logistic regression was used to identify independent risk factors associated with AP severity. Receiver operating characteristic (ROC) curves were generated to assess the predictive performance of each indicator by determining the area under the curve (AUC), sensitivity, specificity, and optimal cutoff values.Results:Compared with the NSAP group, the SAP group had significantly longer hospital stays, higher respiratory rates, and elevated levels of PCT, CRP, absolute neutrophil count, AST, GGT, PT, D-dimer, INR, fibrinogen, FDP, as well as higher CONUT, SIRS, and BISAP scores (all P < 0.05). In contrast, the NSAP group showed significantly higher red blood cell count, hemoglobin, absolute lymphocyte count, serum calcium, albumin, total cholesterol, prothrombin time activity, and PNI score (all P < 0.05). Binary logistic regression analysis identified CONUT score ( OR = 1.623, 95% CI: 1.048–2.512) and BISAP score ( OR = 19.608, 95% CI: 6.585–58.387) as independent risk factors for disease severity. The AUC values for predicting SAP using CONUT score, BISAP score, and their combination were 0.694, 0.815, and 0.864, respectively. Conclusions:The CONUT score is an early independent risk factor for SAP. Combining CONUT with BISAP scores provides better predictive performance for assessing the severity of acute pancreatitis.

Objective:To investigate the application and management status of midline catheters in 1 954 hospitals, providing a basis for optimizing intravenous therapy nursing practices.Methods:This study used convenience sampling. From November 2023, members of the Intravenous Therapy Nursing Professional Committee of the Chinese Nursing Association selected 1 954 hospitals across various regions of China. Questionnaire on the Current Status of Intravenous Therapy in Hospitals at All Levels designed by the committee, based on literature review and expert discussions, was used to collect data on intravenous therapy practices in different hospitals. Multiple response analysis was applied to analysis the results of multiple-choice questions, where response numbers represent the total number of times each option was selected, and response rates refer to the proportion of selected times for each option out of all selected responses.Results:A total of 1 954 questionnaires were distributed across 31 provinces/municipalities/autonomous regions, and 1 954 valid questionnaires were returned, achieving a 100.0% valid response rate. Among the hospitals surveyed, 844 used midline catheters. Regarding the skin disinfection area for midline catheter insertion, the highest response rate was for a range of>20 cm. The highest response rate for catheter insertion techniques was ultrasound-guided Seldinger puncture. The highest response rate for maintenance interval was once a week. The top three responses for nursing documentation related to midline catheters were informed consent for intubation, puncture record, and maintenance record. The most frequently chosen processes were catheter placement, maintenance, removal, and complication management processes. The qualification for midline catheter intravenous therapy specialist nurses was mostly obtained through specialized nurse training, followed by hospital-based and department-based training.Conclusions:The application of midline catheters has rapidly developed but still reveals some deficiencies, including the choice of puncture tools, infection control, and catheter maintenance. It is recommended to improve nursing documentation and management processes related to midline catheters, establish industry standards suitable for China's national conditions, and strengthen and standardize the specialized training of intravenous therapy nurses to promote the healthy development of intravenous therapy in China.

Objective:To analyze inpatients preferences for an unaccompanied ward and its influencing factors, for references for the implementation of unaccompanied ward management.Methods:Based on a convergent mixed research design, a convenience sampling method was used to select inpatients who visited a tertiary hospital from June to August 2024 as the survey subjects. A questionnaire survey was conducted on their willingness to choose the unaccompanied ward (provided by medical nursing staff). Meanwhile, using purposive sampling method, 10 inpatients and 11 accompanying family members were selected for semi-structured interviews about unaccompanied ward prference, and the interview topics were summarized and extracted. The results of quantitative and qualitative were compared and integrated.Results:The quantitative research results showed that among the 805 inpatients included, 125 patients (13.03%) chose medical caregivers, 382 patients (39.83%) chose their spouses, and 272 patients (28.36%) chose their children; 411 patients (24.54%) did not choose medical caregivers due to financial burden; 509 patients (63.23%) believed that the cost of an unaccompanied ward should be less than 120 yuan/day. The qualitative research results showed that the interview data formed three themes, including the driving factors of caregiving form selection intention, the emotional tendency of caregiving form selection intention, and the assessment of the benefits and drawbacks of caregiving form selection intention. The mixed research results showed that the majority of inpatients choose their spouse or children accompany them, and their willingness to choose medical caregivers is mainly influenced by service costs and family labor. However, its did not affect patients who are young or have difficulty caring for them; Influenced by traditional Chinese culture, patients tended to choose relatives to accompany them; The main reasons why patients did not choose unaccompanied wards were the economic burden and the mismatch between medical nursing staff services and their expectations.Conclusions:Inpatients tended to choose family members to accompany them. Their willingness to choose unaccompanied ward was influenced by economic burden, family labor, patient age, caregiving difficulty, and filial piety culture.

Objective:To analyze the genetic variant characteristics of primary immunodeficiency diseases (PID) in families from Henan Province.Methods:This study conducted a retrospective analysis of 19 PID pedigrees referred to the Prenatal Diagnosis Center at Henan Provincial People's Hospital between January 2016 and March 2024. Among the 19 families, 13 underwent prenatal diagnosis at our hospital, while the remaining six received genetic counseling based on third-party genetic testing reports (confirmed by our institution's laboratory). The clinical data from these families were analyzed, and descriptive statistical analysis was applied to the data.Results:Among the 19 PID families, there were seven cases of combined immunodeficiency, three immunodeficiency syndromes, three phagocyte deficiencies, three antibody-dominant immunodeficiencies, and three immunodysregulatory disorders, involving a total of 12 genes ( IL2RG, ADA, RAG2, STAT3, SMARCAL1, ATM, POLA1, CYBB, BTK, RAB27A, LRBA, IL10R). A total of 25 genetic variants were identified, including 11 novel variants not previously documented in the ClinVar and HGMD professional databases. The novel variants comprised: IL2RG gene mutations (Exon5_8del and c.903_904delinsCT leading to p.E302*), ADA gene mutation (c.884A>G resulting in p.D295G), RAG2 gene mutation (c.513dupA causing p.W172Mfs3), POLA1 gene mutation (c.25+5G>C), CYBB gene mutations (c.824G>A/p.G275D and c.472A>T/p.K158), BTK gene mutations (c.522_523insC/p.A175fs and c.142-2A>C), and RAB27A gene mutations (c.121delA/p.T41fs and c.272delA/p.D91fs). Among the 13 families undergoing prenatal diagnosis, genetic testing revealed that 11 fetuses carried wild-type genes, and these families elected to continue their pregnancies. One fetus exhibited identical genetic variants to the proband and received a clinical diagnosis consistent with the genetic disorder, while another fetus demonstrated chromosomal copy number variations. In both of these latter cases, the families opted for pregnancy termination. Conclusion:This study identified 11 unreported variants across seven genes, highlighting the need for further expansion of PID genetic variant databases.

Objective:To investigate the predictive value of procalcitonin to platelet ratio (PPR) and C-reactive protein to albumin ratio (CAR) in severe acute pancreatitis (SAP) and the value of SAP and concomitant acute liver injury (ALI).Methods:Total of 195 patients with AP from June 2021 to December 2022 from 374 patients were screened for inclusion in the study and were divided into non-severe acute pancreatitis (NSAP) and SAP groups. The ALI group was divided into non-acute liver injury (NALI) and ALI groups according to ALI criteria, and then into hepatocellular ALI subgroup, cholangiocellular ALI subgroup and mixed ALI subgroup. Laboratory tests for procalcitonin (PCT), C-reactive protein (CRP), albumin and platelet (PLT) were completed within 48 h. Risk factors for SAP, ALI and each subgroup of ALI were analysed by binary logistic regression. Subject work characteristic (ROC) curves were plotted and the optimal thresholds for PPR and CAR were calculated. The predictive value of PPR, CAR and their combination for SAP, ALI and each type of ALI was determined.Results:The AUCs for predicting SAP by plotting ROC curves and calculating the bedside index score of acute pancreatitis severity (BISAP score), PPR, CAR, PPR combined with CAR, PPR combined with BISAP score, CAR combined with BISAP score and combined PPR, CAR and BISAP score were 0.82, 0.85, 0.79 and 0.86. The areas under the ROC curves for PPR, CAR and combined prediction of ALI were 0.81, 0.85 and 0.88, respectively; the areas under the ROC curves for PPR, CAR and combined prediction of hepatocellular ALI were 0.93, 0.77 and 0.92, respectively; and the areas under the ROC curves for PPR, CAR and combined prediction of cholangiocellular ALI were 0.76, 0.76 and 0.77, respectively. The area under the ROC curves for PPR, CAR and combined prediction of mixed ALI were 0.83, 0.76 and 0.82Conclusions:Elevated PPR and CAR are risk factors for SAP and for the development of ALI in AP. PPR has better predictive value than CAR for hepatocellular and mixed ALI, and CAR has better predictive value than PPR for cholangiocellular ALI.

Objective:To investigate the value of fibrinogen to albumin ratio (FAR), creatinine to albumin ratio (CAR) and platelet to lymphocyte ratio (PLR) in predicting the poor prognosis of hyperlipidemic acute pancreatitis (HLAP).Methods:Clinical data of HLAP patients admitted to the hospital from January 2021 to January and December 2023 were retrospectively collected. According to the prognosis, the patients were divided into two groups: good prognosis group and poor prognosis group.The independent risk factors of HLAP in different prognostic groups were obtained by multivariate Logistic regression analysis. Receiver operating characteristic (ROC) curves were plotted to evaluate the prognostic value of FAR, CAR and PLR alone and in combination.Results:A total of 118 patients with HLAP were included, including 69 patients with good prognosis and 49 patients with poor prognosis.The difference of heart rate, lymphocyte, triglyceride, albumin, creatinine, urea nitrogen, blood calcium, blood glucose, C-reactive protein, procalcitonin, fibrinogen, FAR, CAR, PLR, Bedside indicator of acute pancreatitis Severity score, Acute Physiology and Chronic Health status score, hospitalization time assessment between the two groups was statistically significant ( P<0.05). Multivariate Logistic regression analysis showed that FAR (odds ratio ( OR) = 25.949, 95% confidence interval (95% CI):3.190 ~ 211.080, P = 0.002), CAR ( OR = 1.453, 95% CI:1.095 ~ 1.928, P = 0.010) and PLR ( OR = 1.005, 95% CI: 1.001 ~ 1.009, P = 0.020) were independent risk factors for poor prognosis in HLAP patients. ROC curve analysis showed that the area under the ROC curve (AUC) of FAR, CAR and PLR to predict poor prognosis of HLAP patients were 0.823, 0.781 and 0.652, respectively.The AUC of FAR combined with CAR, FAR combined with PLR and CAR combined with PLR were 0.840, 0.845 and 0.849, respectively.The combined ability of FAR, CAR and PLR to predict poor prognosis in HLAP patients was (AUC=0.875,95% CI:0.814 ~ 0.937). When the cut-off value was 0.387, the sensitivity was 83.7%, and the specificity was 79.7%. Conclusions:The prognostic value of FAR, CAR and PLR in HLAP patients is better than that of single or pairwise combination.
