Objective To explore the work experiences and needs of nutrition specialist nurses,so as to provide a basis in career development and management practices among the nutrition specialist nurses.Methods A method of descriptive phenomenological research was adopted in this study.Purposive sampling was used to select 12 nutrition specialist nurses who came from different regions across the country with over one year of clinical working experiences as well as had completed the specialist training and been qualified by the Nutrition Committee of Guangdong Nursing Association between January and February 2024.Semi-structured on-line interviews were conducted among the participants and the data acquired from the interviews were analysed and summarised.Themes were extracted using NVivo12 and Colaizzi's seven-step analysis from the data from interview.Results Three main themes and eight sub-themes were identified regarding the work experience of nutrition specialist nurses:growth and gains(continuously learning in nutrition therapy-related knowledge to enhance professional skills;actively practice in nutrition therapy to achieve the self-worth);sense of responsibility and mission(increased awareness of responsibility and proactive services;sense of mission to cultivate talents and promotion of the development of nutrition nursing discipline);challenges(lack of an established role in nutrition nursing,conflict in responsibilities;insufficient communication in a medical team regarding nutrition therapy;limited resource to support the development of nutrition nursing;and the professional knowledge and skills unable to fully meet the job demands).Conclusion Hospitals managers should strengthen the support and training for nutrition specialist nurses,clarify their roles,leverage their professional value and promote the career development.

Objective:To evaluate the efficacy and analyze the causes of complications of allogeneic decellularized dermal matrix grafts in the treatment of gingival recession using tunneling technology.Methods:Sixty patients with single or multiple gingival re-cession were randomly divided into an allogeneic decellularized matrix(ADM)group and a connective tissue(SCTG)group.Tunne-ling technique(TUN)were used in both groups to cover the root surface,and the gingival margin position,gingival margin morpholo-gy,and mucogingival junction position of the affected teeth at 1 week,3 weeks,3 months,and 6 months after surgery were observed.Check and record the gingival recession depth(RD)and mean root coverage(MRC)at the implant site before and 6 months after surgery.Record patient satisfaction at 3 weeks and 6 months after surgery.Results:Compared with the traditional SCTG group,the MRC of the ADM group was significantly lower before surgery and 6 months after surgery(P＜0.05).The satisfaction level of the ADM group was higher 3 weeks after surgery,with a significant difference compared to the SCTG group(P＜0.05).But 6 months after surgery,the satisfaction levels of the two groups tended to be consistent,with no significant difference.After TUN+ADM surgery,there was 1 case of abscess infection lesion,and another 3 cases showed local tissue necrosis at the gingival margin one week after surgery.After 3 months of treatment,the gingival color of these 4 patients was pink and tough texture,without swelling and bleeding.Conclusion:Although ADM is slightly inferior to SCTG in the treatment of gingival recession,it may be related to poor postoperative tissue healing complications.However,as long as it is handled properly,long-term follow-up observations have shown that gingival tissue can still achieve complete healing.TUN+ADM is a highly effective treatment for gingival recession and is suitable for further clinical application.

Objective To investigate the therapeutic effect of Sheng Mai San mixed Jiawei Sheng Xian Tang on patients with heart failure with reduced ejection fraction(HFrEF)of Qi deficiency blood stasis type,and its impact on the immune inflammatory response of patients.Methods Ninety patients with HFrEF of Qi deficiency blood stasis type were selected and divided into two groups according to the treatment plan.Patients of the conventional group(42 cases)took sacubitril/valsartan sodium tablets orally.Patients of the combined group(48 cases)were treated with Sheng Mai San combined with Jiawei Sheng Xian Tang on the basis of the conventional group,one dose per day,and divided it in two servings used in the morning and evening.The symptoms of the patients were evaluated by using traditional Chinese medicine(TCM)syndrome score before and after the treatment respectively.Echocardiography technology was used to measure the left ventricular end-diastolic diameter(LVEDD)and left ventricular ejection fraction(LVEF).Enzyme-linked immunosorbent assay was used to detect pentaggrin 3(PTX3),tumor necrosis factor-α(TNF-α),galectin-3(Gal-3),interleukin(IL)-8,IL-6,IL-33 and angiotensin Ⅱ(Ang Ⅱ).N-terminal pro-brain natriuretic peptide(NT-proBNP)was detected by immunofluorescence analysis.The therapeutic effect was evaluated based on the symptoms and the New York Heart Association(NYHA)cardiac function classification in the United States.Results After treatment,the levels of TCM syndrome scores,LVEDD,TNF-α,PTX3,IL-8,IL-6,IL-33,NT-proBNP,Gal-3 and AngⅡ decreased in both groups,and those in the combined group were lower than those in the conventional group(P＜0.05).The LVEF increased,and which were higher in the combined group than those of the conventional group(P＜0.05).After the treatment,the total effective rate of the combined group was higher than that of the conventional group(P＜0.05).Conclusion The Sheng Mai San mixed Jiawei Sheng Xian Tang as adjuvant therapy can effectively reduce the levels of immune inflammatory cytokines in HFrEF patients of Qi deficiency blood stasis type,improve their clinical symptoms and enhance therapeutic effect.

Objective:To explore the experience of emotion management and program needs of patients with vasovagal syncope (VVS) from the doctor-nurse-patient perspective.Methods:This study was a phenomenological study in qualitative research. Using purposive sampling method, four medical specialists, four nursing specialists, and 10 patients with VVS from the Syncope Center of Shanghai East Hospital, Tongji University were selected from March to May 2024 for semi-structured interviews. Colaizzi's phenomenological data analysis was used to analyze the data.Results:Theme 1 was the initial perception and experience of emotion management, in which the doctor-nurse perspective included two sub-themes of emotion management met the actual needs of clinical patients and the management program was too specialized and unknown, and the patient perspective included three sub-themes of differences in the ability of individuals to recognize their own emotional state, lack of knowledge related to emotion management, and lack of social support. Theme 2 was the need for emotion management programs, in which the doctor-nurse perspective involved two sub-themes of multidisciplinary cooperation, suitable for clinical operation and follow-up, and the combination of online and offline, and in-hospital and out-of-hospital linkage, and the patient perspective involved two sub-themes of the need for healthcare guidance, easy to operate, and the diversification of forms, personalization, and meeting the needs of different populations.Conclusions:The content of emotion management is relatively unknown to doctors, nurses and patients, and even more so to patients. VVS emotion management work is still in its infancy, and emotion management as a branch of rehabilitation needs to be emphasized for its development, and psychological assessment and intervention work should be incorporated into the routine of syncope rehabilitation.

Objective:To investigate the temporal expression of Growth Differentiation Factor-15 (GDF15) in the serum of patients with Acute Coronary Syndrome (ACS) and explore the clinical significance of GDF15 in protecting cardiomyocytes in ACS.Methods:A retrospective study was conducted on 289 ACS patients admitted to the emergency departments from February to October 2023. Data on gender, age, troponin T (TnT), creatine kinase isoenzyme (CK-MB), GDF15, and B-type natriuretic peptide (BNP) within 30 minutes of admission were recorded. Differences in these indicators among different groups were compared. Receiver Operating Characteristic (ROC) curves were plotted to evaluate the diagnostic value of GDF15, TnT, and BNP for ACS. Among the patients, 15 exhibited a temporal expression pattern of GDF15, and their blood samples were re-measured using a GDF15 fluorescent quantitative immunochromatographic assay kit. Fifteen patients without temporal expression were randomly selected as controls, and their samples were also re-measured to exclude detection errors. Fifteen patients with temporal expression were included in the temporal expression group, and 15 without temporal expression were included in the non-temporal expression group. Laboratory indicators such as fasting blood glucose, glycated hemoglobin, triglycerides, creatinine, and uric acid were compared between the groups. Additionally, patient age, gender, body mass index (BMI), coronary angiography results, echocardiography, Gensini score, left ventricular ejection fraction (LVEF), and GRACE risk score were recorded to assess their correlation with GDF15 temporal expression. Statistical analysis was performed using SPSS 27 software, with continuous data expressed as mean ± standard deviation (Mean ± SD) and compared using t-tests and χ2 tests. Results:The overall trend in ACS patients showed a higher proportion of males than females (73.36% vs. 26.64%). The oldest group was the Unstable Angina (UA) group, with a mean age of (63.98 ± 15.19) years, while the youngest group was the non-ACS chest pain group, with a mean age of (54.29 ± 16.39) years. A higher proportion of patients in the UA, ST-segment elevation myocardial infarction (STEMI), and non-ST-segment elevation myocardial infarction (NSTEMI) groups had a history of smoking. The combination of GDF15 and TnT showed high diagnostic value for ACS, with an area under the ROC curve (AUC) of 0.843, consistent with previous studies. Among all ACS patients, 15 exhibited a temporal expression pattern of GDF15, where GDF15 levels peaked at 4 hours, gradually decreased, and peaked again at 24 hours. Patients in the temporal expression group had higher LVEF and left ventricular end-systolic diameter compared to the non-temporal expression group. The Gensini score was lower in the temporal expression group, and the GRACE risk score was significantly lower in the temporal expression group (00.7±14.72) compared to the non-temporal expression group (116.1±23.46), with a statistically significant difference ( P = 0.0115). There were no significant differences in general characteristics (age, gender, BMI) or clinical biochemical indicators (fasting blood glucose, glycated hemoglobin, triglycerides, total cholesterol, high-density lipoprotein, low-density lipoprotein, creatinine, uric acid) between the temporal and non-temporal expression groups ( P > 0.05). Conclusions:GDF15 demonstrates significant diagnostic and prognostic predictive value in ACS. Patients with temporally dynamic expression of serum GDF15 exhibit milder myocardial injury and a lower probability of mortality. These findings provide novel therapeutic targets and research directions for further exploring the role of GDF15 in ACS management.

Objective:To evaluate the utility of pulse oximetry-derived parameters—specifically, the pulse oximetry plethysmographic waveform area under the curve (POP AUC) and the peripheral perfusion index (PPI)—in assessing disease severity and predicting prognosis in patients with sepsis. Methods:In this prospective descriptive study, 68 patients with sepsis were categorized based on illness severity into septic shock and non-shock groups, and by 28-day outcome into survival and non-survival groups. POP AUC, PPI, and lactate (Lac) levels were recorded at 0, 24, 48, 72, and 96 hours after admission. APACHEⅡ and SOFA scores were calculated within the first 24 hours. The prognostic value of these parameters was evaluated. Results:Significant differences were observed between the septic shock and non-shock groups in POP AUC, PPI, Lac (all P < 0.05 except at 96 h), APACHEⅡ, and SOFA scores (all P < 0.05). These differences were most pronounced at admission: POP AUC0 (2475.1 ± 899.0) vs. (4260.3 ± 1028.5), PPI 0 (0.78 ± 0.74) vs. (3.13 ± 2.18), Lac 0 (4.95 ± 4.32) vs. (2.07 ± 1.55), APACHE Ⅱ (16.78 ± 5.59) vs. 11.82 ± 4.89), and SOFA (8.89 ± 3.25) vs. (5.06 ± 2.60). Optimal prognostic cut-off values were 2741.43 for POP AUC, 0.97 for PPI, 2.05 for Lac, 12.5 for APACHEⅡ, and 5.5 for SOFA. ROC curve analysis showed that at 24 hours, POP AUC and PPI had significantly larger AUC values than Lac ( P < 0.05), while no significant differences were found among other parameters. Significant differences between non-survivors and survivors were also found in POP AUC, PPI (at 0, 24, and 48 h), APACHE II, and SOFA (all P < 0.05). No significant differences were observed in PPI (72 h and 96 h) or Lac between the two outcome groups. Conclusions:POP AUC and PPI, as derived from pulse oximetry, are non-inferior to Lac, SOFA, and APACHEⅡ scores in evaluating disease severity and predicting 28-day mortality in sepsis patients. These parameters show promise as practical and non-invasive tools for clinical assessment in sepsis.

Objective:To analyze the multidrug resistance and genomic characteristics of Monophasic variant of Salmonella enterica serovar Typhimurium (monophasic Salmonella enterica serovar Typhimurium) isolates from clinical patients and food sources in Henan province. Method:A total of 91 monophasic S.Typhimurium strains isolated from clinical and food sources in Henan from 2021 to 2023 were analyzed for antimicrobial sensitivity and underwent whole genome sequencing. Multilocus sequence typing(MLST), multidrug resistance genes and plasmid types were identified using the sequencing data. Phylogenetic tree based on core genome multilocus sequence typing (cgMLST) and single nucleotide polymorphism (SNP) sites was constructed to analyze the genetic evolutionary relationship by comparing with international popular strains in public databases. The Chi-square test was used to compare drug resistance rates. Results:No significant difference was observed in the drug resistance rates between the clinical strains and food strains in Henan [82.19%(60/73) and 11/18, χ2=2.614, P=0.106]. The overall multidrug resistance (MDR) rate was 78.02%(71/91). Most strains were resistant to ampicillin, tetracycline chloramphenicol, β-lactam and sulfonamides. Resistance genes carried by the isolates varied, as well as the drug-resistant phenotypes. MLST showed that 91 strains of S.Typhimurium belonged to ST34 and carried aminoglycoside acetyltransferase gene aac(6′)-Iaa and mobile genetic elements such as plasmids IncQ1 and IncHI2/IncHI2A. The results of cgMLST typing phylogenetic trees showed that food and clinical isolates from the same region in Henan were identified as the same cgST type and clustered in the same branch, which indicated the risk for cross-infection between animal and human. The phylogenetic tree of monophasic S.Typhimurium constructed based on SNP sites showed that the majority of monophasic S.Typhimurium strains in Henan were close to the strains from other provinces in China, other strains were close to the strains from Europe and Southeast Asia, suggesting the possibility of cross regional transmission of the strains. Pork was identified as the main food source. Conclusion:The prevalent ST type of monophasic S.Typhimurium isolated from Henan was ST34, which carried multiple antibiotic resistance genes and widespread drug resistance phenotypes. Most of the monophasic S.Typhimurium isolates in Henan showed a specific phylogenetic lineage with the foreign epidemic strains, indicating the possibility of dissemination of strains between humans and food.
