Performance of nutritional and inflammatory markers in patients with pancreatic cancer.

BACKGROUND: Systemic inflammation and nutrition play pivotal roles in cancer progression and can increase the risk of delayed recovery after surgical procedures. AIM: To assess the significance of inflammatory and nutritional indicators for the prognosis and postoperative recovery of patients with pancreatic cancer (PC). METHODS: Patients who were diagnosed with PC and underwent surgical resection at our hospital between January 1, 2019, and July 31, 2023, were enrolled in this retrospective observational cohort study. All the data were collected from the electronic medical record system. Seven biomarkers - the albumin-to-globulin ratio, prognostic nutritional index (PNI), systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), nutritional risk index (NRI), and geriatric NRI were assessed. RESULTS: A total of 446 patients with PC met the inclusion criteria and were subsequently enrolled. Patients with early postoperative discharge tended to have higher PNI values and lower SII, NLR, and PLR values (all P < 0.05). Through multivariable logistic regression analysis, the SII value emerged as an independent risk factor influencing early recovery after surgery. Additionally, both univariable and multivariable Cox regression analyses revealed that the PNI value was the strongest prognostic marker for overall survival (OS; P = 0.028) and recurrence-free survival (RFS; P < 0.001). The optimal cutoff PNI value was established at 47.30 using X-tile software. Patients in the PNI-high group had longer OS (P < 0.001) and RFS (P = 0.0028) times than those in the PNI-low group. CONCLUSION: Preoperative systemic inflammatory-nutritional biomarkers may be capable of predicting short-term recovery after surgery as well as long-term patient outcomes.

Can a one-on-one mentorship program reduce the turnover rate of new graduate nurses in China? A longitudinal study.

Nursing graduates experience "reality shock" upon entering the workplace as well as face challenges and stress during their transition from nursing student to qualified nurse. The high turnover rate of new graduate nurses not only increases an organization's human resources costs but also results in a shortage of nurses. In particular, a poor experience during the transition from nursing student to qualified nurse can lead to significant turnover. A three-year longitudinal study was conducted to assess the effectiveness of one-on-one mentorship program in reducing the turnover rate of nurses in China. A total of 199 new graduate nurses, recruited in 2013, were considered the control group and received a basic preceptorship, and 239 nurses in 2014 were considered the experimental group, for which a one-on-one mentorship program was implemented. Propensity-score-matching analysis was conducted to adjust the baseline of the two groups, and survival analysis was performed to compare the two groups. The findings showed that the turnover rates for the experimental group were 3.77%, 3.48%, and 8.11% as compared to 14.07%, 9.36%, and 14.19% for the control group at the end of the first three years, respectively. The survival curves of the two groups were significantly different (p < 0.001). The turnover rate for the first year in the experimental group was significantly lower than that for the control group, but the rates in the second and third years were not different. The results indicate that a one-on-one mentorship program is beneficial for the retention of new graduate nurses, particularly during the first year.

[Abnormal processing characteristics to basic emotional faces in the early phase in children with autism spectrum disorder].

OBJECTIVE: To explore the recognition ability and abnormal processing characteristics to basic emotional faces in the early phase in children with autism spectrum disorders (ASD). METHODS: Photos of Chinese static faces with four basic emotions (fearful, happy, angry and sad) were used as stimulus. Twenty-five ASD children and twenty-two age- and gender-matched typical developed children (normal controls) were asked to match the emotional faces with words. Event-related potential (ERP) data were recorded concurrently. RESULTS: N170 latencies for total emotion and fearful face in the left temporal region were faster than in the right one in normal controls (P<0.05), but the results were not noted in ASD children. Further, N170 latencies in the left temporal region of ASD children were slower than normal controls for total emotion, fearful and happy faces (P<0.05), and their N170 latencies in the right temporal region were prone to slower than normal controls for angry and fearful faces. CONCLUSIONS: The holistic perception speed of emotional faces in the early cognitive processing phase in ASD children is slower than normal controls. The lateralized response in the early phase of recognizing emotional faces may be aberrant in children with ASD.

[Association between intelligence development and facial expression recognition ability in children with autism spectrum disorder].

OBJECTIVE: To investigate the features of intelligence development, facial expression recognition ability, and the association between them in children with autism spectrum disorder (ASD). METHODS: A total of 27 ASD children aged 6-16 years (ASD group, full intelligence quotient >70) and age- and gender-matched normally developed children (control group) were enrolled. Wechsler Intelligence Scale for Children Fourth Edition and Chinese Static Facial Expression Photos were used for intelligence evaluation and facial expression recognition test. RESULTS: Compared with the control group, the ASD group had significantly lower scores of full intelligence quotient, verbal comprehension index, perceptual reasoning index (PRI), processing speed index（PSI), and working memory index (WMI) (P<0.05). The ASD group also had a significantly lower overall accuracy rate of facial expression recognition and significantly lower accuracy rates of the recognition of happy, angry, sad, and frightened expressions than the control group (P<0.05). In the ASD group, the overall accuracy rate of facial expression recognition and the accuracy rates of the recognition of happy and frightened expressions were positively correlated with PRI (r=0.415, 0.455, and 0.393 respectively; P<0.05). The accuracy rate of the recognition of angry expression was positively correlated with WMI (r=0.397; P<0.05). CONCLUSIONS: ASD children have delayed intelligence development compared with normally developed children and impaired expression recognition ability. Perceptual reasoning and working memory abilities are positively correlated with expression recognition ability, which suggests that insufficient perceptual reasoning and working memory abilities may be important factors affecting facial expression recognition ability in ASD children.

[Event-related potential of working memory on emotional faces in children with autism spectrum disorder].

OBJECTIVE: To investigate the characteristics of working memory ability on emotional faces and related event-related potential (ERP) in children with autism spectrum disorder (ASD). METHODS: The Chinese Facial Affective Picture System was used as test material, and the event-related potential system was used to record the electroencephalographic data when 16 ASD children aged 6-12 years (ASD group) and 14 normal children matched for age (control group) were completing the facial emotion delayed match-to-sample task. The characteristics of P3b component were analyzed for both groups. RESULTS: Compared with the control group, the ASD group had a significantly longer reaction time (1 527 ms vs 1 060 ms; P<0.05) and a significantly lower accuracy rate (76% vs 88%; P<0.01) in the facial emotion delayed match-to-sample task. There was a difference in the amplitude of P3b component during the encoding stage between the two groups. In the ASD group, the P3b component on the left side electrode had a higher amplitude than that on the right side electrode (P<0.05), while the control group had no such characteristics. CONCLUSIONS: There is a difference in P3b component during the encoding stage between school-aged ASD children and normal children. In ASD children, working memory on emotional faces may depend more on the related neural pathway in the left hemisphere.
