Longitudinal associations between smartphone multitasking and depressive symptoms in college students / 中国学校卫生

Objective@#To explore the longitudinal correlation between smartphone multitasking and depressive symptoms, so as to provide an evidence based basis for promoting the mental health of college students.@*Methods@#A total of 967 college students were recruited from one university in Taiyuan, Chongqing, and Shenzhen cities, China, by using multi stage randomized cluster sampling from October to December 2021 at baseline, and a follow up survey was conducted in May 2022. Smartphone multitasking behaviors were assessed by means of the Assessment of Smartphone Multitasking for Adolescents (ASMA), and depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9) among college students. Chi square tests were performed to compare the differences in depressive symptoms between different groups of demographic characteristics, and binary Logistic regression models were employed to analyze the associations between smartphone multitasking and depressive symptoms among college students.@*Results@#The rates of depressive symptoms among college students at baseline and follow up were 35.2% and 42.3%, respectively. Compared to the low level smartphone multitasking index group at baseline, the moderate and high level groups were more likely to experience depressive symptoms at baseline (moderate level group: OR=1.74, 95%CI =1.22-2.50, high level group: OR=2.77, 95%CI =1.94-3.95) and followup (moderate level group: OR=1.41, 95%CI =1.01-1.95, high level group: OR=1.64, 95%CI =1.17-2.29) ( P <0.05). In addition, compared to the persistently low smartphone multitasking index, increased risk of depressive symptoms was associated with maintaining a moderate to high ( OR=2.94, 95%CI =1.83-4.71), and a higher ( OR=2.07, 95%CI =1.31-3.27) or lower smartphone multitasking index ( OR=2.02, 95%CI =1.27-3.19) ( P <0.05). Moreover, higher smartphone multitasking index scores were positively associated with the risk of new-onset depressive symptoms at follow up ( OR=1.87, 95%CI=1.07-3.27, P <0.05).@*Conclusions@#Smartphone multitasking behaviors are find to be associated with an increased risk of depressive symptoms in college students. There is a need to reduce smartphone multitasking in order to decrease depressive symptoms and promote students mental health.

Mismatched donor cell infusion-related syndrome following microtransplant in patients with acute myeloid leukemia / 中华医学杂志(英文版)

BACKGROUND@#Immunotherapies such as adoptive immune cell infusion and immune-modulating agents are widely used for cancer treatment, and the concomitant symptoms, including cytokine release syndrome (CRS) or immune-related adverse events (irAEs), are frequently reported. However, clinical manifestations induced by mismatched donor granulocyte colony-stimulating factor mobilized peripheral blood mononuclear cell (GPBMC) infusion in patients receiving microtransplant (MST) have not yet been well depicted.@*METHODS@#We analyzed 88 cycles of mismatched GPBMC infusion in patients with acute myeloid leukemia receiving MST and 54 cycles of chemotherapy without GPBMC infusion as a comparison. Clinical symptoms and their correlation with clinical features, laboratory findings, and clinical response were explored.@*RESULTS@#Fever (58.0% [51/88]) and chills (43.2% [38/88]) were the significant early-onset symptoms after GPBMC infusion. Patients possessing less human leukocyte antigen-matching loci with the donor or those with unrelated donors experienced more chills (3 [2-5] loci vs. 5 [3-5] loci, P  = 0.043 and 66.7% [12/18] vs. 37.1% [26/70], P  = 0.024). On the other hand, those with decreased CD4 + /CD8 + T-cell ratio developed more fever (0.8 [0.7-1.2] vs. 1.4 [1.1-2.2], P  = 0.007). Multivariable analysis demonstrated that younger patients experienced more fever (odds ratio [OR] = 0.963, 95% confidence interval [CI]: 0.932-0.995, P  = 0.022), while patients with younger donors experienced more chills (OR = 0.915, 95% CI: 0.859-0.975, P  = 0.006). Elevated ultra-sensitive C-reactive protein levels in the absence of cytokine storm were observed following GPBMC infusion, which indicated mild and transient inflammatory response. Although no predictive value of infusion-related syndrome to leukemia burden change was found, the proportion of host pre-treatment activated T cells was positively correlated with leukemia control.@*CONCLUSIONS@#Mismatched GPBMC infusion in MST induced unique infusion-related symptoms and laboratory changes, which were associated with donor- or recipient-derived risk factors, with less safety and tolerance concerns than reported CRS or irAEs.

Clinical effects of stereotactic-guided endoscopic hematoma removal combined with early systematic rehabilitation training on hypertensive intracerebral hemorrhage in the basal ganglia / 中国基层医药

Objective:To investigate the clinical effects of stereotactic-guided endoscopic hematoma removal combined with early systematic rehabilitation training on hypertensive intracerebral hemorrhage in the basal ganglia.Methods:A total of 130 patients with hypertensive intracerebral hemorrhage in the basal nucleus who received treatment in Zhejiang Veteran Hospital from June 2019 to December 2021 were included in this randomized control study. They were randomly divided into a control group and a study group ( n = 65 per group). The control group received minimally invasive hematoma puncture. The study group received stereotactic-guided neuroendoscopic hematoma removal. After surgery, early systematic rehabilitation training was carried out, and surgical indicators were recorded. The levels of serum inflammatory factors and stress factors were determined. The recurrence, death, and complications as well as prognosis of cerebral hemorrhage were recorded in each group. Results:The operative time in the study group was (85.39 ± 5.24) minutes, which was significantly longer than (64.17 ± 4.31) minutes in the control group ( t = -14.56, P < 0.001). Hematoma clearance rate in the study group was (94.66 ± 5.18) %, which was significantly higher than (76.82 ± 5.39) % in the control group ( t = -17.63, P < 0.001). At 24 hours after surgery, tumor necrosis factor-α, interleukin-1, norepinephrine, and hydrocortisone levels in the study group were (68.29 ± 5.36) ng/L, (237.62 ± 13.87) ng/L, (75.39 ± 5.82) μg/L, and (30.96 ± 2.97) μg/L, respectively, which were significantly lower than (74.61 ± 5.62) ng/L, (295.47 ± 14.69) ng/L, (91.62 ± 6.41) μg/L, and (38.25 ± 3.16) μg/L in the control group ( t = 7.95, 18.42, 16.84, 11.75, all P < 0.001). There was no significant difference in the 6-month mortality rate between the two groups ( P > 0.05). The recurrence rate of cerebral hemorrhage and the overall incidence of complications in the study group were (1.54% (1/65) and (10.77% (7/65) in the study group, respectively, which were significantly lower than 12.31% (8/65) and 27.69% (18/65) in the control group ( χ2 = 4.30, 5.99, both P < 0.05). The overall excellent and good prognosis rate within 6 months in the study group was 86.15% (56/65), which was significantly higher than 67.69% (44/65) in the control group ( χ2 = 6.24, P < 0.05). Conclusion:Compared with minimally invasive hematoma puncture and drainage surgery, stereotactic-guided neuroendoscopic hematoma removal takes longer time, but it can better effectively increase hematoma removal rate and alleviate stress and inflammatory reactions in patients with hypertensive intracerebral hemorrhage in the basal ganglia. Early systematic rehabilitation training combined with stereotactic guided neuroendoscopic hematoma removal can help reduce the risk of recurrence and complications of cerebral hemorrhage and improve prognosis.

Study on drug sensitivity against Comamonas testosteroni by Kirby-Bauer disk diffusion method / 中南大学学报(医学版)

OBJECTIVE@#To determine the drug resistance of Comamonas testosteroni (C. testosteroni) by the Kirby-Bauer (K-B) method without Clinical and Laboratory Standards Institute (CLSI) explanation or the minimum inhibitory concentration (MIC) method with the standard CLSI explanation to evaluate the sensitivity of K-B method in detection of C. testosteroni.
@*METHODS@#K-B method and MIC method was used to determine the sensitivity of C. testosteroni to Piperacillin, Cefepime, Piperacillin/tazobactam, Imipenem, Meropenem, Amikacin, Gentamicin, Tobramycin, Ceftazidime and Ciprofloxacin. The interpretation standard for Pseudomonas aeruginosa was temporary used for the K-B method. The coincident rate was compared between the two methods.
@*RESULTS@#The complete or partial coincident rate for K-B method and MIC method to detect Piperacillin and Cefepime was 97.4% or 2.6%; the complete coincidence rate to detect Piperacillin/tazobactam, Imipenem and Meropenem was 100%; the complete or partial coincident rate to detect Amikacin, Gentamicin and Tobramycin 94.7% or 5.3%; the complete or partial coincident rate to detect Ceftazidime was 97.4% or 2.6%; the complete or partial coincident rate to detect Ciprofloxacin 86.8% or 10.6%, and the full non-coincidence rate was 2.6%.
@*CONCLUSION@#The results of drug sensitive test from the two methods are highly consistent. We suggest that the microbiology labs do not report the interpretive results for C. testosteroni with K-B method but report the test results.
