Objective: Metastases in the supragastric lesser sac (SGLS) are not only occult but are also barriers to complete resection of ovarian cancer. We describe a cohort of patients with SGLS disease undergoing debulking surgery. Methods: We identified all patients who underwent evaluation and eventual resection of SGLS disease as part of cytoreductive surgery for stage IIIC–IVB high-grade epithelial ovarian cancer at our institution from January 2018 to August 2022. Results: Thirty-three of 286 patients (11.5%) underwent resection of SGLS disease.Metastases in the SGLS were identified by preoperative imaging in 4 of 33 patients (12.1%). The median peritoneal cancer index score was 22 (range, 9–33). Through surgical exploration, metastases were frequently seen in the right diaphragm (100%), hepatorenal recess (97%), lesser omentum (81.8%), left diaphragm (78.8%), supracolic omentum (75.8%), anterior transverse mesocolon (72.7%), splenic hilum (63.6%), ligamentum teres hepatis (60.6%), and gallbladder fossa (51.5%). The lesser omentum was normal in 6 of 33 (18.2%) patients, despite metastases within the SGLS. A total of 54.5% of patients underwent complex surgery (surgical complexity scores; median, 8; range, 3–14). Complete resections were achieved in 19 (57.6%) patients. No complications were related to the resection of SGLS disease. The median length of progression-free survival was 24.8 months (95% confidence interval=16.6–32.9). Conclusion Metastases to the SGLS are not uncommon in advanced ovarian cancer, particularly those with widely disseminated disease. Disease in this recess is rarely identified by preoperative imaging and deserves systematic surgical exploration to attain complete cytoreduction.

Background: The Lymphadenectomy in Ovarian Neoplasms (LION) study revealed that systemic lymphadenectomy did not bring survival benefit for advanced ovarian cancer patients with clinically normal lymph nodes and was associated with a higher incidence of operative complications. However, there is no consensus on whether lymphadenectomy has survival benefit or not in early epithelial ovarian cancer (EOC). Methods We designed the LOVE study, a multicenter, randomized controlled, phase III trial to compare the efficacy and safety of comprehensive staging surgery with or without lymphadenectomy in stages IA-IIB EOC and fallopian tube carcinomas (FTC). The hypothesis is that the oncological outcomes provided by comprehensive staging surgery without lymphadenectomy are non-inferior to those of conventional completion staging surgery in early-stage EOC and FTC patients who have indications for post-operative adjuvant chemotherapy. Patients assigned to experimental group will undergo comprehensive staging surgery, but lymphadenectomy. Patients assigned to comparative group will undergo completion staging surgery including systematic pelvic and para-aortic lymphadenectomy. All subjects will receive 3–6 cycles of standard adjuvant chemotherapy. Major inclusion criteria are pathologic confirmed stage IA-IIB EOC or FTC, and patients have indications for adjuvant chemotherapy either confirmed by intraoperative fast frozen section or previous pathology after an incomplete staging surgery. Major exclusion criteria are non-epithelial tumors and low-grade serous carcinoma. Patients with severe rectum involvement which lead to partial rectum resection will be excluded. The sample size is 656 subjects. Primary endpoint is disease-free survival.

Objective To evaluate the effects of spinal manipulation therapy (SMT) on chronic nonspecific neck pain (CNSNP) by using World Health Organization Family International Classifications (WHO-FICs). Methods Randomized controlled trials (RCTs) about the effects of SMT on CNSNP were searched from PubMed, Web of Science, Cochrane Library, EMBASE, EBSCO, CBM and CNKI from database establishment to December 31st, 2021. At least two researchers extracted the data. Cochrane bias risk assessment tool and Physiotherapy Evidence Database Scale were used to evaluate the quality of the included articles. Revman 5.4 software and Stata 16.0 software were used for meta-analyses and publication bias analysis respectively. Results A total of 15 RCTs that represented 1 067 participants were evaluated. In terms of body functions, compared with the control group, SMT significantly reduced Visual Analog Score for pain (MD = -0.85, 95%CI -1.06 to -0.63, P < 0.00001) and Numerical Rating Scale (MD = -0.92, 95%CI -1.29 to -0.55, P < 0.001), increased pressure pain thresholds (SMD = 0.67, 95%CI 0.47 to 0.86, P < 0.001), cervical range of motion (ROM) of flexion/extension (SMD = 0.51, 95%CI 0.33 to 0.68, P < 0.001) and rotation (SMD = 0.20, 95%CI 0.01 to 0.38, P = 0.04), improved root mean square of cervical muscles electromygraphy (MD = 2.17, 95%CI 0.06 to 4.29, P = 0.04), but not significantly in cervical ROM of lateral flexion (SMD = 0.19, 95%CI -0.00 to 0.38, P = 0.06), cervical strength (SMD = -0.18, 95%CI -0.84 to 0.49, P = 0.60) and endurance (SMD = 0.18, 95%CI -0.39 to 0.75, P = 0.53). In term of activities and participation, SMT significantly improved cervical disability (MD = -0.96, 95%CI -1.55 to -0.38, P = 0.001), but not significantly in health status of patients with CNSNP (SMD = 0.08, 95%CI -0.03 to 0.20, P = 0.15). Conclusion SMT could improve pain intensity, pain sensitivity, cervical ROM and disability in patients with CNSNP, but its efficacy on muscle function, proprioception and health status is unclear.

ObjectiveTo conduct a bibliometric analysis of the research status and hot spots of physical fitness for children and adolescents with intellectual disability using CiteSpace. MethodsBased on the theoretical framework of World Health Organization Family of International Classifications (WHO-FICs), literatures about physical fitness for children and adolescents with intellectual disability were searched in PubMed from 2012 to 2022. CiteSpace 6.1.R2 was used to draw knowledge mapping. ResultsA total of 670 literatures were retrieved from PubMed, and 348 literatures were included. The mean number of articles published was 31.6 per year, which presented an upward trend. The characteristics and intervention strategies of physical fitness for children and adolescents with intellectual disabilities, such as Down syndrome, autism spectrum disorder and Prader-Willi syndrome had been the hot spots of research in the past ten years. Under the guidance of the WHO-FICs framework, physical fitness involved structural and functional levels (body composition/obesity, bone health, motor development/motor skills, postural control, etc.), activity and participation levels (physical activity/sedentary behavior, quality of life, etc.), and environmental and personal factors (parental support, etc.). Intervention included physical fitness strategies (aerobic exercise, moderate-to-vigorous physical activity, video games, resistance training, etc.), motor skills training strategies (adaptive physical activity, adaptive physical education, etc.), and sport event related strategies (Special Olympic soccer, etc.). ConclusionThe international attention on the physical fitness for children and adolescents with intellectual disabilities has been increasing in the past decade. Researches focus on the dysfunction of physical fitness for children and adolescents with intellectual disabilities, such as Down syndrome and autism spectrum disorder; in terms of physical structure and function including body composition and executive ability, etc., and in terms of social and participation including physical activity and quality of life, etc.. In addition, physical fitness intervention strategies, such as traditional physical fitness exercise, moderate-to-vigorous physical activity, adaptive physical activity, adaptive sports and special Olympic sports are also research hotspots. Those strategies adhere to the concept of "sports for life" and are closely linked with daily life, in order to help them to improve their physical and mental health level, social participation ability, quality of life and well-being.

We proposed a new deep learning model by analyzing electroencephalogram signals to reduce the complexity of feature extraction and improve the accuracy of recognition of fatigue status of pilots. For one thing, we applied wavelet packet transform to decompose electroencephalogram signals of pilots to extract the δ wave (0.4-3 Hz), θ wave (4-7 Hz), α wave (8-13 Hz) and β wave (14-30 Hz), and the combination of them was used as de-nosing electroencephalogram signals. For another, we proposed a deep contractive auto-encoding network-Softmax model for identifying pilots' fatigue status. Its recognition results were also compared with other models. The experimental results showed that the proposed deep learning model had a nice recognition, and the accuracy of recognition was up to 91.67%. Therefore, recognition of fatigue status of pilots based on deep contractive auto-encoding network is of great significance.

Objective To explore the curative effectiveness of comprehensive voice training methods on teachers' voice disorders patients by using subjective and objective assessment. Methods Forty-seven teachers' voice disorders patients suffering from voice symptoms without organic disease and complete follow-up data as the research object were treated with a three-month comprehensive voice training program. Training content included relieving laryngeal muscle tension, improving the throat vocal cord movement and reconstruction methods of pronunciation. The use of voice acoustic analysis and voice handicap index(VHI) were compared before and after training. Results The jitter and shimmer were significantly decreased after comprehensive voice training from 1.06(0.79,1.38)％and 2.71(2.16,3.24)％to 0.78 (0.59, 0.99)％ and 1.64(1.03,2.45)％, the differences were significant (Z=3.249,-4.121, P<0.05). Maximum phonation time and dysphonia severity index were significantly increased obviously from (9.87 ± 2.61)s and-2.23±0.75 to (12.81±1.97)s and-0.43±1.65 respectively, the differences were significant (t=-6.057,-5.273, P<0.05). After the training, the VHI score of voice disorder index decreased from (37.41±4.96)points to (26.31± 4.29) points after the comprehensive voice training. In addition to emotional function, the difference was statistically significant(t=12.715, 5.881, 11.483, P<0.05). Conclusions Voice training can reduce the degree of voice disorders effectively, increase the power of the respiratory system, therefore improve the voice quality of teachers with voice disorders. The subjective and objective combination assessment can evaluate the quality of the patient′s voice more thoroughly and evaluate the clinical efficacy of voice training further.

Purpose To compare the CTPA image quality by using contrast agent with different concentration at different injection rate so as to provide suitable contrast agent injection for patients.Materials and Methods A total of 346 patients with suspected acute pulmonary embolism who required to undergo CTPA examination were randomly assigned to high (370 mgI/ml) and low (320 mgI/ml) concentration groups,and each group was further divided into six subgroups with different velocity (3.0,3.2,3.4,3.6,3.8 and 4.0 ml/s).The CT value of the main pulmonary artery,right pulmonary upper lobe artery and right lung under leaf posterior basal segmental artery was measured.Results In the high concentration group,there were no significant differences in pulmonary artery average CT value,noise,single to noise ratio (SNR) and contrast to noise ratio (CNR) among the subgroups with different velocity (P＞0.05).In the low concentration group,the difference was not statistically significant in pulmonary artery average CT value (P＞0.05) among the subgroups with different velocity;however,the noise,SNR and CNR of 3.0 ml/s subgroup had significant differences compared with other subgroups (P＜0.05).There was no significant difference in average CT value of pulmonary artery between the subgroups with the same velocity in the two concentration groups (P＞0.05).In addition,except that the noise,SNR and CNR of 3.0 ml/s subgroup showed significant differences with other subgroups either in high concentration group or in low concentration group (P＜0.05),there were no significant differences in the above-mentioned parameters among other subgroups with the same velocity in both groups (P＞0.05).Conclusion Compared with high concentration contrast agent,the image obtained by using low concentration contrast agent shows no difference in pulmonary artery average CT value but with low iodine flow and iodine flow rate,which can reduce the risks of contrast media induced nephropathy (CIN) and contrast agent extravasation.
