Objective:To estimate the incidence of pediatric bronchiolitis obliterans syndrome (BOS) after hematopoietic stem cell transplantation (HSCT) by meta-analysis, and to provide scientific basis for postoperative respiratory follow-up management.Methods:We searched PubMed, Embase, Web of science, Chinese Medical Journal full-text database, Wanfang data, and China National Knowledge Network database to obtain related studies on postoperative BOS in children with HSCT from March 31, 2023. Literature screening, quality evaluation and information extraction were carried out, and Stata 16.0 software was used for analysis.Results:A total of 19 literatures were included, with a total sample size of 3 955 and 180 cases of BOS. The meta-analysis showed that the incidence of BOS after HSCT was 4%(95% CI: 3%-5%), and the heterogeneity was I2=76.1%( P<0.01). Heterogeneity among studies was explained by different regions of the study population, different BOS diagnostic criteria, study sample size, and subgroup analysis of single or multi-center studies. Sensitivity analysis showed that the results were stable, but publication bias was detected. Conclusions:The incidence of BOS in children after HSCT is 4%, but there is a large heterogeneity, and more large-scale multi-center studies are needed to determine the incidence. Pediatricians should conduct scientific management and follow-up of children after HSCT, so as to make early diagnosis and treatment and timely detection of BOS, and improve the quality of life of children.

Objective To explore the application effect of personalized lateral decubitus pillow for patients with cervical spine surgery. Methods A totals of 106 patients after cervical spine surgery were recruited and randomly divided into control group (48 cases) and experimental group (58 cases). Patients in the control group used the common pillow when patients lay lateral position-the height of pillow equal to shoulder cheekbone breadth, while experimental group used the personalized lateral decubitus pillow which supported suspended occipitalis and the height of pillow adjusted by individual. The comfort score, incision pain score and last time for lateral position of all patients were compared. Results The comfort score of the experimental group was significantly higher than that of the control group during the first day, second day and the third day after surgery [(66. 3 ± 4. 8) vs (63. 4 ± 3. 5), (68. 4 ± 5. 3) vs (65. 1 ± 4. 6), (71. 3 ± 4. 8) vs (68. 3 ± 4. 4);t=3. 461,3. 473,3. 270, respectively; P <0. 05]. The incision pain score of the experimental group was significantly lower than that of the control group during the first day, second day and the third day after surgery [(5.09±1.33) vs(5.88±1.29),(4.78±1.30) vs(5.52±1.09),(4.33±1.13) vs(5.06±1.06);t=3. 127,3. 157,3. 427, respectively;P<0. 05]. The last time of the experimental group for lateral position were longer than that of control group [(88. 6 ± 15. 2) min vs (79. 3 ± 14. 1) min; t = -3. 239,P =0. 002]. Conclusions It can increase the comfort score, extend the last time for lateral position and lessen incision pain to use the individuation lateral position pillow for patients after cervical spine surgery.
