Acute lymphoblastic leukemia (ALL) accounts for 75%-85% of the cases of childhood leukemia. As a result of the progress made in diagnosis and treatment, an event-free survival rate of 70%–80% has been reported in our country. Consequently, research should focus on long-term physical function and quality of life of childhood ALL survivors. In the past 20 years, cancer rehabilitation has achieved rapid development in European and American countries, but gaps remain in clinical practice and academic research of rehabilitation for childhood leukemia. Specifically, rehabilitation for childhood leukemia in our country lags behind, compared with that in Western developed countries. In this commentary, we describe a relatively comprehensive childhood ALL survivorship care quality framework to improve patients' long-term quality of life.

Objective:To evaluate the effect of perioperative transcutaneous electrical acupoint stimulation (TEAS) on postoperative cellular immune function in the patients undergoing posterior spinal internal fixation.Methods:Ninety patients, aged 40-70 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective posterior spinal internal fixation in our hospital, were divided into 2 groups ( n=45 each) using a computer-generated table of random numbers: routine group and experiment group.Total intravenous anesthesia was used in routine group, while total intravenous anesthesia combined with TEAS was applied in experiment group.In experiment group, bilateral Zusanli and Sanyinjiao acupoints were stimulated with 2/15 Hz disperse-dense waves at the intensity that could be tolerated by patients at 30 min before induction of anesthesia, maintaining with 2/100 Hz disperse-dense waves from the end of induction until the end of operation at the same stimulation intensity before induction.Bilateral Neiguan and Taichong acupoints were stimulated for 30 min each time with 2/15Hz disperse-dense waves once a day at 1st-4th days after operation.In routine group, the electrodes were connected at the same time period, but no stimulation was given.Venous blood samples were collected before induction of anesthesia, at 1 h after surgery, and on 1st, 3rd, and 5th days after surgery, and the percentage of CD3 + , CD4 + , CD8 + T lymphocytes, CD4 + /CD8 + ratio, WBC count and percentage of neutrophils (NE%) were determined by flow cytometry, and the consumption of intraoperative anesthetics, use of postoperative analgesics, nausea and vomiting, dizziness, infection and length of hospital stay were recorded. Results:Compared with routine group, the total consumption and consumption index of remifentanil were significantly decreased, the percentage of CD3 + T lymphocytes was increased on 3rd and 5th postoperative days, the NE% was decreased on 1st postoperative day, and the incidence of dizziness was decreased ( P<0.05), and no significant change was found in the other indicators in experiment group ( P>0.05). Conclusions:Perioperative TEAS can improve postoperative cellular immune function and has a certain potential value in preventing postoperative infection in the patients undergoing posterior spinal internal fixation.

Background::Coronavirus disease 2019 (COVID-19) has potential risks for both clinically worsening pulmonary hypertension (PH) and increasing mortality. However, the data regarding the protective role of vaccination in this population are still lacking. This study aimed to assess the safety of approved vaccination for patients with PH.Methods::In this national prospective cohort study, patients diagnosed with PH (World Health Organization [WHO] groups 1 and 4) were enrolled from October 2021 to April 2022. The primary outcome was the composite of PH-related major adverse events. We used an inverse probability weighting (IPW) approach to control for possible confounding factors in the baseline characteristics of patients.Results::In total, 706 patients with PH participated in this study (mean age, 40.3 years; mean duration after diagnosis of PH, 8.2 years). All patients received standardized treatment for PH in accordance with guidelines for the diagnosis and treatment of PH in China. Among them, 278 patients did not receive vaccination, whereas 428 patients completed the vaccination series. None of the participants were infected with COVID-19 during our study period. Overall, 398 patients received inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine, whereas 30 received recombinant protein subunit vaccine. After adjusting for baseline covariates using the IPW approach, the odds of any adverse events due to PH in the vaccinated group did not statistically significantly increase (27/428 [6.3%] vs. 24/278 [8.6%], odds ratio = 0.72, P = 0.302). Approximately half of the vaccinated patients reported at least one post-vaccination side effects, most of which were mild, including pain at the injection site (159/428, 37.1%), fever (11/428, 2.6%), and fatigue (26/428, 6.1%). Conclusions::COVID-19 vaccination did not significantly augment the PH-related major adverse events for patients with WHO groups 1 and 4 PH, although there were some tolerable side effects. A large-scale randomized controlled trial is warranted to confirm this finding. The final approval of the COVID-19 vaccination for patients with PH as a public health strategy is promising.

Background::The potential impact of pre-existing coronary artery stenosis (CAS) on acute pulmonary embolism (PE) episodes remains underexplored. This study aimed to investigate the association between pre-existing CAS and the elevation of high-sensitivity cardiac troponin I (hs-cTnI) levels in patients with PE.Methods::In this multicenter, prospective case-control study, 88 cases and 163 controls matched for age, sex, and study center were enrolled. Cases were patients with PE with elevated hs-cTnI. Controls were patients with PE with normal hs-cTnI. Coronary artery assessment utilized coronary computed tomographic angiography or invasive coronary angiography. CAS was defined as ≥50% stenosis of the lumen diameter in any coronary vessel >2.0 mm in diameter. Conditional logistic regression was used to evaluate the association between CAS and hs-cTnI elevation.Results::The percentage of CAS was higher in the case group compared to the control group (44.3% [39/88] vs. 30.1% [49/163]; P = 0.024). In multivariable conditional logistic regression model 1, CAS (adjusted odds ratio [OR], 2.680; 95% confidence interval [CI], 1.243–5.779), heart rate >75 beats/min (OR, 2.306; 95% CI, 1.056–5.036) and N-terminal pro-B type natriuretic peptide (NT-proBNP) >420 pg/mL (OR, 12.169; 95% CI, 4.792–30.900) were independently associated with elevated hs-cTnI. In model 2, right CAS (OR, 3.615; 95% CI, 1.467–8.909) and NT-proBNP >420 pg/mL (OR, 13.890; 95% CI, 5.288–36.484) were independently associated with elevated hs-cTnI. Conclusions::CAS was independently associated with myocardial injury in patients with PE. Vigilance towards CAS is warranted in patients with PE with elevated cardiac troponin levels.
