BACKGROUND:Fatigue is one of the most common neurological symptoms reported post coronavirus disease 2019 (COVID-19) infection. In order to establish effective early intervention strategies, more emphasis should be placed on the correlation between fatigue and cortical neurophysiological changes, especially in healthcare workers, who are at a heightened risk of COVID-19 infection. METHODS:A prospective cohort study was conducted involving 29 COVID-19 medical workers and 24 healthy controls. The assessment included fatigue, sleep and health quality, psychological status, and physical capacity. Functional near-infrared spectroscopy (fNIRS) was employed to detect activation of brain regions. Bilateral primary motor cortex (M1) excitabilities were measured using single- and paired-pulse transcranial magnetic stimulation. Outcomes were assessed at 1, 3, and 6 months into the disease course. RESULTS:At 1-month post-COVID-19 infection, 37.9% of patients experienced severe fatigue symptoms, dropping to 10.3% at 3 months. Interestingly, the remarkable decreased activation/excitability of bilateral prefrontal lobe (PFC) and M1 were closely linked to fatigue symptoms after COVID-19. Notably, greater increase in M1 region excitability correlated with more significant fatigue improvement. Re-infected patients exhibited lower levels of brain activation and excitability compared to single-infection patients. CONCLUSIONS:Both single infection and reinfection of COVID-19 lead to decreased activation and excitability of the PFC and M1. The degree of excitability improvement in the M1 region correlates with a greater recovery in fatigue. Based on these findings, targeted interventions to enhance and regulate the excitability of M1 may represent a novel strategy for COVID-19 early rehabilitation.

AIMS:Neurogenic bladder (NB) is a prevalent and debilitating consequence of spinal cord injury (SCI). Indeed, the accurate prognostication of early bladder outcomes is crucial for patient counseling, rehabilitation goal setting, and personalized intervention planning. METHODS:A retrospective exploratory analysis was conducted on a cohort of consecutive SCI patients admitted to a rehabilitation facility in China from May 2016 to December 2022. Demographic, clinical, and electrophysiological data were collected within 40 days post-SCI, with bladder outcomes assessed at 3 months following SCI onset. RESULTS:The present study enrolled 202 SCI patients with a mean age of 40.3 ± 12.3 years. At 3 months post-SCI, 79 participants exhibited complete bladder emptying. Least absolute shrinkage and selection operator (LASSO) and multivariate logistic regression analyses identified the H-reflex of the soleus muscle, the American Spinal Injury Association Lower Extremity Motor Score (ASIA-LEMS), and the time from lesion to rehabilitation facility (TLRF) as significant independent predictors for bladder emptying. A scoring system named HALT was developed, yielding a strong discriminatory performance with an area under the receiver operating characteristics curve (aROC) of 0.878 (95% CI: 0.823-0.933). A simplified model utilizing only the H-reflex exhibited excellent discriminatory ability with an aROC of 0.824 (95% CI: 0.766-0.881). Both models demonstrated good calibration via the Hosmer-Lemeshow test and favorable clinical net benefits through decision curve analysis (DCA). In comparison to ASIA-LEMS, both the HALT score and H-reflex showed superior predictive accuracy for bladder outcome. Notably, in individuals with incomplete injuries, the HALT score (aROC = 0.973, 95% CI: 0.940-1.000) and the H-reflex (aROC = 0.888, 95% CI: 0.807-0.970) displayed enhanced performance. CONCLUSION:Two reliable models, the HALT score and the H-reflex, were developed to predict bladder outcomes as early as 3 months after SCI onset. Importantly, this study provides hitherto undocumented evidence regarding the predictive significance of the soleus H-reflex in relation to bladder outcomes in SCI patients.

Introduction Lung cancer is the most common cancer in China, with the highest mortality rate. Surgery is the primary treatment for early lung cancer. However, patients with lung cancer have a heavy burden of symptoms within 3 months after surgery, which seriously affects their quality of life (QOL). The symptom management model based on the patient-reported outcome (PRO) is considered the best caregiving model. The clinical evidence about the symptom management of lung cancer within 3 months after the operation is very limited. Herein, we propose a randomized controlled trial to evaluate the PRO score-based monitoring and alert system for follow-up on psychological and physiological symptoms of lung cancer patients within 3 months after surgery and further investigate the effect of intervention measures based on this PRO score-based system. Methods and analysis This multicenter, open-label, randomized, parallel superiority trial will be conducted at four hospitals in China. A total of 440 lung cancer patients will be recruited in this study, who will be randomly assigned to the intervention group or the control group in a ratio of 1:1. Any of the target symptoms reaches the preset threshold (score ≥ 4), the patients will accept the symptom management advices based on the PRO. The patients in the control group will follow the current standard procedure of symptom management. The symptom management system is an electronic management system based on WeChat mini programs. All patients will be evaluated for symptoms through the lung cancer module of the MDASI lung cancer-specific scale on the day before surgery, days 1, 3, 5, and 7 after surgery, and once a week during the 12-week post-discharge period. Simultaneously, the EORTC QLQ-C30 scale will be used to evaluate patients’ quality of life at baseline and the fourth and twelfth week after the surgery. The mean number of symptom threshold events of the intervention and the control groups were compared by t -test, and the changes of PRO were compared by a mixed effect model. The primary endpoint has been set as the 12-week post-discharge period. Discussion This study will test the feasibility of the symptom management system based on the mobile social media applet in postoperative caregiving and the efficacy of psychiatrist-assisted treatment and provide evidence in managing the symptoms of patients in the medium and long term.

Side effects from chemotherapy may disturb healthy eating. There are many food taboos among Chinese patients with cancer treated with chemotherapy; they may be conservative in food intake and seek help from traditional Chinese medicine to adjust to healthy eating. Differences in eating cultures may lead Chinese patients with cancer to generate different knowledge, attitudes, and behaviors toward healthy eating. This systematic review explored the knowledge, attitudes, and behaviors toward healthy eating and summarized influencing factors among Chinese patients with cancer treated with chemotherapy. Two English and three Chinese databases were searched since 2007. The eligibility criteria were quantitative descriptive studies, participants who were adult Chinese patients with cancer who received chemotherapy, and primary outcomes that included knowledge, attitudes, or behaviors toward healthy eating. A total of 12 studies were identified. The 11-item tool from the Agency for Healthcare Research and Quality was used to assess quality. All studies were of moderate quality. Narrative qualitative analysis was considered to summarize the findings, and the results were reported by scores or percentages. Four studies measured knowledge, and the information about what to eat and how much to eat was contradictory and confused patients, with little known about Chinese food therapy. Ten studies involved attitudes, and patients were aware of the importance and willingness for eating guidance before, during, and after chemotherapy. Strategies to relieve vomiting and nausea, engage in healthy food choices, and seek food therapy were the main behaviors. The influencing factors were found only in behaviors, including demographic and psychological factors. Knowledge, attitudes, and behaviors toward healthy eating are not satisfactory and need to be improved. More high-quality studies should regard health behavior as a distal outcome and explore the influences of knowledge and attitudes on behaviors.

BACKGROUND The opinions on the efficacy and safety of no anticoagulation versus regional citrate anticoagulation for continuous KRT (CKRT) were controversial in patients with severe liver failure with a higher bleeding risk. We performed a randomized controlled trial to assess no anticoagulation versus regional citrate anticoagulation for CKRT in these patients. METHODS Adult patients with liver failure with a higher bleeding risk who required CKRT were considered candidates. The included participants were randomized to receive regional citrate anticoagulation or no-anticoagulation CKRT. The primary end point was filter failure. RESULTS Of the included participants, 44 and 45 were randomized to receive regional citrate anticoagulation and no-anticoagulation CKRT, respectively. The no-anticoagulation group had a significantly higher filter failure rate (25 [56%] versus 12 [27%], P = 0.003), which was confirmed by cumulative incidence function analysis and sensitive analysis including only the first CKRT sessions. In the cumulative incidence function analysis, the cumulative filter failure rates at 24, 48, and 72 hours of the no-anticoagulation and regional citrate anticoagulation groups were 31%, 58%, and 76% and 11%, 23%, and 35%, respectively. Participants in the regional citrate anticoagulation group had significantly higher incidences of Ca2+tot/Ca2+ion >2.5 (7% versus 57%, P < 0.001), hypocalcemia (51% versus 82%, P = 0.002), and severe hypocalcemia (13% versus 77%, P < 0.001). However, most (73%) of the increased Ca2+tot/Ca2+ion ratios were normalized after the upregulation of the calcium substitution rate. In the regional citrate anticoagulation group, there was no significant additional increase in the systemic citrate concentration after 6 hours. CONCLUSIONS For patients with liver failure with a higher bleeding risk who required CKRT, regional citrate anticoagulation resulted in significantly longer filter lifespan than no anticoagulation. However, regional citrate anticoagulation in patients with liver failure was associated with a significantly higher risk of hypocalcemia, severe hypocalcemia, and Ca2+tot/Ca2+ion >2.5.

Empathic pain has attracted the interest of a substantial number of researchers studying the social transfer of pain in the sociological, psychological, and neuroscience fields. However, the neural mechanism of empathic pain remains elusive. Here, we establish a long-term observational pain model in mice and find that glutamatergic projection from the insular cortex (IC) to the basolateral amygdala (BLA) is critical for the formation of observational pain. The selective activation or inhibition of the IC-BLA projection pathway strengthens or weakens the intensity of observational pain, respectively. The synaptic molecules are screened, and the upregulated synaptotagmin-2 and RIM3 are identified as key signals in controlling the increased synaptic glutamate transmission from the IC to the BLA. Together, these results reveal the molecular and synaptic mechanisms of a previously unidentified neural pathway that regulates observational pain in mice.

Taking ischemic and bleeding risks into consideration, insufficient data exist on dual antiplatelet therapy after percutaneous coronary intervention in elderly Chinese patients with coronary artery disease. We aimed to investigate the effectiveness and safety of ticagrelor in comparison with clopidogrel on a background of aspirin for elderly Chinese patients with coronary artery disease 12 months after percutaneous coronary intervention. A single-center retrospective cohort study was conducted. Selected from patients with coronary artery disease aged ≥ 75 years from January 2010 to July 2019, 908 eligible subjects receiving dual antiplatelet therapy after percutaneous coronary intervention for up to 12 months were consecutively enrolled in the study. The included patients received ticagrelor in combination with aspirin (n = 264) or clopidogrel in combination with aspirin (n = 644). Effectiveness endpoints were evaluated by the major adverse cardiovascular events, encompassing all-cause death, non-fatal myocardial infarction, and clinically driven revascularization. The safety endpoints were recorded as the incidence of Bleeding Academic Research Consortium bleeding. The patients who were treated with ticagrelor were slightly younger than those who were treated with clopidogrel (79.1 ± 3.7 vs 80.7 ± 4.5 years, p < 0.01). The ticagrelor cohort contained a higher percentage of patients undergoing a prior percutaneous coronary intervention (37.9% vs 24.5%, p < 0.01), and a lower percentage of smokers (19.3% vs 27.2%, p < 0.05), compared with the clopidogrel cohort. The levels of glucose, total cholesterol, and low-density lipoprotein-cholesterol in the ticagrelor group were higher while the level of triglycerides and high-density lipoprotein-cholesterol were lower (p < 0.05) than those in the clopidogrel group. Left main percutaneous coronary intervention was performed more frequently among the ticagrelor-treated patients (23.5% vs 9.3%, p < 0.01), while patients in the clopidogrel group underwent more left circumflex percutaneous coronary intervention (34.3% vs 23.1%, p < 0.01). We found that ticagrelor was associated with a lower incidence of major adverse cardiovascular events than clopidogrel using the inverse probability of treatment weighting model (odds ratio, 0.493; 95% confidence interval 0.356–0.684). There was no difference in terms of the risk of Bleeding Academic Research Consortium bleeding between the two groups (p > 0.05). Ticagrelor was associated with a lower incidence of major adverse cardiovascular events than clopidogrel at 12 months in elderly Chinese patients with coronary artery disease, without a significant increase of Bleeding Academic Research Consortium bleeding events.

Objective To examine whether the employees of an oil and gas company in Shaanxi Province are more vulnerable to hypertension than the general residents, aged 18-60, living in the same geographical region. Design Cross-sectional analysis of the hypertension prevalence of two different population by using propensity score matching (PSM). Participants Employees of Changqing Oil Field Filiale took part in Health Risk Factors Survey (2013) and residents took part in the National Health Service Survey (2013) in Shaanxi Province, China. Main outcome measures The primary outcome was hypertention which was defined as systolic blood pressure of at least 140 mm Hg, or diastolic blood pressure of at least 90 mm Hg, or self-reported antihypertensive medication use in the previous 2 weeks, or self-reported history of hypertention. Results Changqing employees were much younger, with a higher proportion of men, and their lifestyle was less healthy, with higher BMI, more drinkers and smokers. Before PSM, hypertension prevalence of Changqing employees was slightly lower than Shaanxi residents (5.8% vs 7.6%). After PSM, the results of the adjusted logistic model showed that Changqing employees were more likely to be hypertensive ( OR =1.10, 95% CI =1.02-1.19, P =0.01). Among the male samples, Changqing employees were more likely to be hypertensive ( OR =1.43, 95% CI =1.31-1.58, P <0.01), while the opposite was true for the female samples (OR=0.64, 95%CI=0.56-0.73, P<0.01). Conclusion Changqing’s employees, as a whole, and male employees in particular, were more vulnerable to hypertension than the general residents of the region. However, the reverse was found for female employees.

Objective Accurate blood pressure measurement is important for both the patients and the health service in appropriate treatment and estimation of clinical risk. Few automated devices have been shown to be accurate when compared with mercury sphygmomanometer. This study presents the validation results of the Andon KD-391 semiautomated blood pressure monitor according to the International Protocol of the European Society of Hypertension (ESH) in an adult population.Methods Sequential measurements of systolic and diastolic blood pressures were obtained in 33 participants who fulfilled the requirements of the International Protocol using the mercury sphygmomanometer (two observers) and the test device (one supervisor). According to the ESH validation protocol, 99 couples of test device and reference blood pressure measurements were obtained during the two phases of the study (three pairs for each of the 33 participants).Results In phase 1, the Andon KD-391 device produced 29, 38 and 44 measurements for systolic blood pressure and 28, 39 and 43 for diastolic blood pressure failing within the zones 5, 10 and 15 mmHg, respectively. The test device also passed phase 2 of the validation study with a mean (+/- SD) device-observer difference of -0.17 +/- 7.07 mmHg for systolic and -1.01 +/- 5.95 mmHg for diastolic blood pressure.Conclusion According to the results of the validation study on the basis of the ESH International Protocol, the Andon KD-391 can be recommended for clinical use in an adult population.
