Introduction: Detrended fluctuation analysis (DFA) is a well-established method to evaluate scaling indices of time series, which categorize the dynamics of complex systems. In the literature, DFA has been used to study the fluctuations of reaction time Y(n) time series, where n is the trial number.
Methods: Herein we propose treating each reaction time as a duration time that changes the representation from operational (trial number) time n to event (temporal) time t, or X(t). The DFA algorithm was then applied to the X(t) time series to evaluate scaling indices. The dataset analyzed is based on a Go-NoGo shooting task that was performed by 30 participants under low and high time-stress conditions in each of six repeated sessions over a 3-week period.
Results: This new perspective leads to quantitatively better results in (1) differentiating scaling indices between low versus high time-stress conditions and (2) predicting task performance outcomes.
Conclusion: We show that by changing from operational time to event time, the DFA allows discrimination of time-stress conditions and predicts performance outcomes.
Background: To evaluate the influence of sodium bicarbonate Ringer's solution (BRS) combined with positive end-expiratory pressure (PEEP) on the internal environment in patients who have undergone laparoscopic bariatric surgery.
Methods: A total of 128 patients undergoing laparoscopic bariatric surgery were randomly divided into the control group (group C), the PEEP group (group P), the BRS group (group B), and the BRS combined with the PEEP group (group BP). The results of arterial blood gas analysis, including pH value, base excess (BE), concentrations of electrolyte, and lactate (Lac) were documented before intravenous infusion (T0) and 5 min after the surgery (T1).
Purpose: Survival for childhood Acute Lymphoblastic Leukaemia (ALL) has surpassed 90%, making quality of survival an important endpoint in treatment outcomes. This study examined health-related quality of life (HRQoL) trajectories in early survivorship for patients post-ALL treatment compared with a matched group of healthy peers, and explored the association of individual factors (age, sex) and treatment intensity with HRQoL outcomes.
Methods: Eighty-three paediatric patients aged 4-16 years who recently completed treatment for ALL were recruited to the study, alongside 53 age- and sex-matched healthy children.

Background: Rapid human movement plays a crucial role in the spatial dissemination of the dengue virus. Nevertheless, robust quantification of this relationship using both spatial and temporal models remains necessary. This study aims to explore the spatial and temporal patterns of dengue transmission under various human movement contexts.
Background: This study compared short- and mid-term outcomes of hemihepatectomy (HH) and pancreatoduodenectomy (PD) in patients with extrahepatic cholangiocarcinoma, focusing on surgical outcomes, body composition, and nutritional status.
Method: A retrospective review was conducted to assess short-term outcomes, including operative time, blood loss, complications, and mortality. Body composition and nutritional parameters were analyzed preoperatively and 1 year postoperatively.

Objective: This study aimed to observe the impact of Tthoracic paravertebral nerve blockade(TPVB) at left T7 level on the α7nAChR-dependent cholinergic anti-inflammatory pathway in patients undergoing thoracoscopic lobectomy.
Methods: Scheduled thoracoscopic lung surgery patients at the First Affiliated Hospital of Nanchang University from August to September 2023 were divided into two groups according to the surgical site. The experimental group underwent left T7 paravertebral nerve blockade (LTPVB group), while the control group underwent right T7 paravertebral nerve blockade (RTPVB group).
