Difference in Rumor Dissemination and Debunking Before and After the Relaxation of COVID-19 Prevention and Control Measures in China: Infodemiology Study.

BACKGROUND: The information epidemic emerged along with the COVID-19 pandemic. While controlling the spread of COVID-19, the secondary harm of epidemic rumors to social order cannot be ignored. OBJECTIVE: The objective of this paper was to understand the characteristics of rumor dissemination before and after the pandemic and the corresponding rumor management and debunking mechanisms. This study aimed to provide a theoretical basis and effective methods for relevant departments to establish a sound mechanism for managing network rumors related to public health emergencies such as COVID-19. METHODS: This study collected data sets of epidemic rumors before and after the relaxation of the epidemic prevention and control measures, focusing on large-scale network rumors. Starting from 3 dimensions of rumor content construction, rumor propagation, and rumor-refuting response, the epidemic rumors were subdivided into 7 categories, namely, involved subjects, communication content, emotional expression, communication channels, communication forms, rumor-refuting subjects, and verification sources. Based on this framework, content coding and statistical analysis of epidemic rumors were carried out. RESULTS: The study found that the rumor information was primarily directed at a clear target audience. The main themes of rumor dissemination were related to the public's immediate interests in the COVID-19 field, with significant differences in emotional expression and mostly negative emotions. Rumors mostly spread through social media interactions, community dissemination, and circle dissemination, with text content as the main form, but they lack factual evidence. The preferences of debunking subjects showed differences, and the frequent occurrence of rumors reflected the unsmooth channels of debunking. The χ2 test of data before and after the pandemic showed that the P value was less than .05, indicating that the difference in rumor content before and after the pandemic had statistical significance. CONCLUSIONS: This study's results showed that the themes of rumors during the pandemic are closely related to the immediate interests of the public, and the emotions of the public accelerate the spread of these rumors, which are mostly disseminated through social networks. Therefore, to more effectively prevent and control the spread of rumors during the pandemic and to enhance the capability to respond to public health crises, relevant authorities should strengthen communication with the public, conduct emotional risk assessments, and establish a joint mechanism for debunking rumors.

A study on the factors influencing the intention to receive booster shots of the COVID-19 vaccine in China based on the information frame effect.

Introduction: In the response to and prevention and control of the Novel coronavirus pneumonia, the COVID-19 vaccine does not provide lifelong immunity, and it is therefore important to increase the rate of booster shots of the COVID-19 vaccine. In the field of information health science, research has found that information frames have an impact in changing individual attitudes and health behaviors. Objective: This study focuses on the effects of different influencing factors on the public's willingness to receive the booster shots of the COVID-19 vaccine under two information frameworks. Methods: An online questionnaire was conducted to explore the effects of demographic characteristics, personal awareness, social relationships, risk disclosure, perceived booster vaccination protection rate, and duration of protection under the assumption of an information framework. T test and one-way analysis were used to testing the effect of variables. Results: (1) The persuasion effect under the gain frame is higher than that under the loss frame (B = 0.863 vs. B = 0.746); (2) There was no significant difference in subjects' intention of booster vaccination in terms of gender, age, income, occupation, educational background and place of residence. Whether family members received booster vaccination was strongly correlated with their intention of vaccination under the loss framework (p = 0.017, M = 4.63, SD = 0.664). (3) The higher the understanding of COVID-19, the higher the degree of compliance with the government's COVID-19 prevention and control measures, and the higher the willingness to strengthen vaccination; (4) Risk disclosure has a significant impact on people's willingness to receive COVID-19 booster shots (M = 2.48, under the loss framework; M = 2.44, under the gain framework); (5) Vaccine protection rate and duration of protection have an impact on people's willingness to vaccinate. Increased willingness to vaccinate when the protection rate of booster vaccine approaches 90% (M = 4.76, under the loss framework; M = 4.68, under the gain framework). When the vaccine protection period is 2 years, people are more willing to receive a booster vaccine; and the willingness to receive a booster shot is stronger under the loss framework (M = 4.60, SD = 0.721, p = 0.879). Conclusion: The impact of the information framework on COVID-19 vaccination intentions is different, and the disclosure of relevant health information should focus on the impact of the information framework and content on the public's behavior toward strengthening vaccination. Therefore, in the face of public health emergencies, public health departments, healthcare institutions, and other sectors can consider adopting the Gainful Information Framework tool to disseminate health information to achieve better persuasion and promote public health behavior change enhancing public health awareness, and promoting universal vaccination.

The Association Between Linguistic Characteristics of Physicians' Communication and Their Economic Returns: Mixed Method Study.

BACKGROUND: Web-based health care has the potential to improve health care access and convenience for patients with limited mobility, but its success depends on active physician participation. The economic returns of internet-based health care initiatives are an important factor that can motivate physicians to continue their participation. Although several studies have examined the communication patterns and influences of web-based health consultations, the correlation between physicians' communication characteristics and their economic returns remains unexplored. OBJECTIVE: This study aims to investigate how the linguistic features of 2 modes of physician-patient communication, instrumental and affective, determine the physician's economic returns, measured by the honorarium their patients agree to pay per consultation. We also examined the moderating effects of communication media (web-based text messages and voice messages) and the compounding effects of different communication features on economic returns. METHODS: We collected 40,563 web-based consultations from 528 physicians across 4 disease specialties on a large, web-based health care platform in China. Communication features were extracted using linguistic inquiry and word count, and we used multivariable linear regression and K-means clustering to analyze the data. RESULTS: We found that the use of cognitive processing language (ie, words related to insight, causation, tentativeness, and certainty) in instrumental communication and positive emotion-related words in affective communication were positively associated with the economic returns of physicians. However, the extensive use of discrepancy-related words could generate adverse effects. We also found that the use of voice messages for service delivery magnified the effects of cognitive processing language but did not moderate the effects of affective processing language. The highest economic returns were associated with consultations in which the physicians used few expressions related to negative emotion; used more terms associated with positive emotions; and later, used instrumental communication language. CONCLUSIONS: Our study provides empirical evidence about the relationship between physicians' communication characteristics and their economic returns. It contributes to a better understanding of patient-physician interactions from a professional-client perspective and has practical implications for physicians and web-based health care platform executives.

Comparison of clinical efficacy of da Vinci robot-assisted lung cancer surgery with two-, three- and four-hole approaches.

Orifice reduction strategies for da Vinci robotic surgery have been a hot topic of research in recent years. We retrospectively analyzed the perioperative outcomes of robotic-assisted thoracoscopic surgery (RATS) with two, three, and four-hole approaches in radical lung cancer surgery. Our results revealed that the two-hole group has advantages in terms of operative time, postoperative 3-day drainage, postoperative drainage time, postoperative hospital stay and postoperative day 3 visual analogue scale (VAS) pain scores. There were no significant differences between the three groups in terms of intraoperative bleeding, number of lymph nodes dissected, VAS pain scores on postoperative days 1 and 2, and postoperative complications. In addition, the two-hole group was superior to the three-hole and four-hole groups in terms of C-reactive protein (CRP), procalcitonin (PCT) and interleukin 10 (IL-10). In summary, the RATS two-hole approach has advantages in operation time, rapid recovery after operation and some postoperative inflammatory indicators, and is worth promoting in hospitals that are skilled in three-hole and four-hole da Vinci robot surgery and have conditions.

Effect of da Vinci robot versus thoracoscopic surgery on lung function and oxidative stress levels in NSCLC patients: a propensity score-matched study.

BACKGROUND: To evaluate the short-term efficacy, lung function, and oxidative stress levels between the robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery group (VATS) for non-small cell lung cancer (NSCLC). METHODS: We conducted a retrospective cohort study, selecting 248 NSCLC patients who underwent minimally invasive lobectomy at the Department of Thoracic Surgery, Gansu Provincial People's Hospital, from August 2019 to February 2023. There were 105 patients in the RATS group and 143 patients in the VATS group. The patients in the two groups were subjected to 1:1 propensity score matching analysis (PSM), and the perioperative indicators were recorded. The levels of oxidative stress factors (superoxide dismutase, SOD; malondialdehyde, MDA) and inflammatory factors were measured 1 day before surgery and 3 days after surgery, respectively. Pulmonary function and patient quality of life were measured at 1 day preoperatively and 3 months postoperatively. RESULTS: There are 93 patients in each group after PSM. Compared to the VATS group, the RATS group had shorter operation time, less intraoperative blood loss, greater number and groups of lymph nodes cleared, and shorter postoperative hospital stay. The SOD level in the RATS group was higher and the MDA level was lower than that in the VATS group after surgery. Postoperative inflammatory cytokine levels were less elevated in the RATS group than in the VATS group. At 3 months postoperatively, FVC%, FEV1%, and GQOLI-74 scores were higher in the RATS group than in the VATS group. CONCLUSION: Compared to VATS lobectomy, RATS lobectomy has the advantages of shorter operative time, lesser bleeding, more lymph node dissection, faster postoperative recovery, and lesser impact on postoperative lung function. It is also capable of reducing the postoperative oxidative stress and inflammatory response, which can improve patients' quality of life.

Multi-mode joint modulation of array wireless power transfer.

In this paper, an array multi-transmitter multi-mode wireless power transfer system is proposed. The system realizes the joint modulation of three transmitter coil working modes of single transmitter coil, dual transmittercoil and four transmitter coils in the wireless power transfer system through PI closed-loop control, which can realize the stable output of WPT system in three different transmitter coil work modes. It effectively compensates for the shortcomings of the single working mode of a single transmitter coil and the limited range of effective working areas, and improves the robustness of the wireless power transfer system.

Comparison of Clinical Efficacy Between Da Vinci Robot-Assisted Ivor Lewis Esophagectomy and McKeown Esophagectomy for Middle and Lower Thoracic Esophageal Cancer: A Multicenter Propensity Score-Matched Study.

BACKGROUND: We compared the perioperative efficacy and safety of da Vinci robot-assisted Ivor Lewis esophagectomy and McKeown esophagectomy for middle and lower thoracic esophageal cancer. METHODS: A retrospective case-control study method was used. A total of 181 patients with esophageal cancer admitted to three medical centers in China from February 2018 to October 2022 were collected and divided into two groups according to surgical method: da Vinci robot-assisted thoracic surgery (RATS) Ivor Lewis esophagectomy (Ivor Lewis group) and RATS McKeown esophagectomy (McKeown group), respectively. Propensity score matching (PSM) analysis was used to reduce selection bias caused by confounding factors. The perioperative indicators of the two groups were compared and analyzed. RESULTS: There was a statistically significant difference in age and tumor location between the Ivor Lewis group and the McKeown group. After PSM, the above factors were no longer statistically significant. There were 80 patients in each group after PSM. In terms of operative time (P = 0.005), anastomotic leakage (P = 0.029), and pulmonary infection (P = 0.035), the Ivor Lewis group has significant advantages; in terms of the number of lymph nodes dissected around the recurrent laryngeal nerve (P = 0.010), the McKeown group has significant advantages. CONCLUSION: Both RATS Ivor Lewis esophagectomy and McKeown esophagectomy are safe and effective for treatment of middle and lower thoracic esophageal cancer. Ivor Lewis has advantages in operative time, anastomotic leakage, and pulmonary infection, while McKeown has advantage in lymph node dissection around the recurrent laryngeal nerve.

Meta analysis of the diagnostic value of circulating miRNA in benign and malignant pulmonary nodules.

OBJECTIVE: A meta-analysis was conducted to assess the impact of miRNAs in circulation on diagnosing benign and malignant pulmonary nodules (BPNs and MPNs). METHODS: Electronic databases such as Embase, PubMed, Web of Science, and The Cochrane Library were utilized for diagnostic tests of circulating miRNAs to diagnose BPNs and MPNs from the library creation to February 2023. Meta-analysis of the included literature was performed using Stata 16, Meta-Disc 1.4, and Review Manager 5.4 software. This study determined the combined sensitivity, specificity, diagnostic ratio (DOR), positive/negative likelihood ratios (PLR/NLR), as well as value of area under the receiver operating characteristic (ROC) curve. RESULTS: This meta-analysis included 14 publications and 17 studies. According to our findings, the pooled sensitivity for miRNA in diagnosing benign and malignant pulmonary nodules was 0.82 [95% CI (0.74, 0.88)], specificity was 0.84 [95% CI (0.79, 0.88)], whereas the DOR was 22.69 [95% CI (13.87, 37.13)], PLR was 5.00 [95% CI (3.87, 6.46)], NLR was 0.22 [95% CI (0.15, 0.32)], and the area under the working characteristic curve (AUC) of the subject was 0.89 [95% CI (0.86, 0.91)]. CONCLUSION: Circulating miRNAs could be used with sensitivity, specificity, DOR, PLR, NLR, and AUC as biomarkers to diagnose pulmonary nodules (PNs). However, more research is needed to determine the optimum miRNA combinations for diagnosing PNs due to the significant heterogeneity on previous studies.

Efficacy and Quality of Life with the Modified Versus the Traditional Thoraco-Laparoscopic McKeown Procedure for Esophageal Cancer: A Multicenter Propensity Score-Matched Study.

BACKGROUND: This study aimed to compare the efficacy and postoperative quality of life for patients with esophageal cancer treated by either the modified or the traditional thoracolaparoscopic McKeown procedure. METHODS: This retrospective case-control study included 269 patients with esophageal cancer admitted to three medical centers in China from February 2020 to August 2022. The patients were divided according to surgical method into the layered hand-sewn end-to-end invagination anastomosis group (modified group) and the traditional hand anastomosis group (traditional group). Propensity score-matching (PSM) was used to maintain balance and comparability between the two groups. RESULTS: The differences in age and tumor location between the patients in the traditional and modified groups were statistically significant. After PSM, the aforementioned factors were statistically insignificant. After PSM, each group had 101 patients. The modified group showed the greater advantage in terms of postoperative hospital stay (P = 0.036), incidence of anastomotic leak (P = 0.009), and incidence of gastroesophageal reflux (P < 0.001), and the difference was statistically significant. The results of the Quality of Life Questionnaire Core 30 (QLQ-C30) and Quality of Life Questionnaire Oesophageal Cancer Module 18 (QLQ-OES18) scales showed that the modified group also had the advantage over the traditional group in terms of physical function, overall health status, loss of appetite, eating, reflux, obstruction, and loss of appetite scores at the first and third months after surgery. CONCLUSION: The modified thoraco-laparoscopic McKeown procedure is a safe and effective surgical approach that can significantly reduce the incidence of postoperative anastomotic leak and gastroesophageal reflux, shorten the postoperative hospital stay, and improve the postoperative quality of life for patients with esophageal cancer.

Effect of Early Versus Late Oral Feeding on Postoperative Complications and Recovery Outcomes for Patients with Esophageal Cancer: A Systematic Evaluation and Meta-Analysis.

BACKGROUND: This study aimed to systematically evaluate the effect of early oral feeding (EOF) versus late oral feeding (LOF) on postoperative complications and rehabilitation outcomes for patients with esophageal cancer. METHODS: This study searched relevant literature published up to March 2023 by computer retrieval of PubMed, Embase, The Cochrane Library, and Web of Science. A meta-analysis was performed using Review Manager 5.4 software to compare the effects of EOF and LOF on postoperative complications and recovery outcomes of patients with esophageal cancer. RESULTS: The study included 14 articles, including 9 retrospective studies, 4 randomized controlled trials (RCTs), and 1 prospective study. The 2555 patients included in the study comprised 1321 patients who received EOF and 1234 patients who received LOF. The results of the meta-analysis showed that compared with the LOF group, the EOF group has a shorter time to the first flatus postoperatively (mean difference [MD], - 1.12; 95% confidence interval [CI], (- 1.25 to - 1.00; P < 0.00001), a shorter time to the first defecation postoperatively (MD, - 1.31; 95% CI, - 1.67 to - 0.95;, P < 0.00001], and a shorter hospital stay postoperatively (MD, - 2.87; 95% CI, - 3.84 to - 1.90; P < 0.00001). The two groups did not differ significantly statistically in terms of postoperative anastomotic leakage rate (P = 0.10), postoperative chyle leakage rate (P = 0.10), or postoperative pneumonia rate (P = 0.15). CONCLUSION: Early oral feeding after esophageal cancer surgery can shorten the time to the first flatus and the first defecation postoperatively, shorten the hospital stay, and promote the recovery of patients. Moreover, it has no significant effect on the incidence of postoperative complications.

Efficacy of Using Maryland Forceps Versus Electrocoagulation Hooks in RATS Lung Cancer Surgery: A Propensity Score-Matched Study.

BACKGROUND: Here we compare the difference in recent outcomes between the use of Maryland forceps (MF) and electrocoagulation hooks (EH) in robotic-assisted thoracoscopic radical lung cancer resection. PATIENTS AND METHODS: We retrospectively analyze the clinical data of 247 patients with lung cancer who underwent robotic-assisted thoracoscopic surgery from February 2018 to December 2022. On the basis of the intraoperative use of energy devices, we divided the clinical data into two groups, including 84 cases in the MF group and 163 cases in the EH group, respectively. The patients in the two groups were matched with propensity score matching analysis, and further, the perioperative clinical data of the two groups were compared. RESULTS: Compared with the EH group, patients in the MF group had shorter operative time, lesser intraoperative bleeding, shorter postoperative drainage time, and shorter postoperative hospital stay (P < 0.05). By comparing the intraoperative and postoperative complications in the two groups, it was found that the incidence of intraoperative lymph node fragmentation, the incidence of postoperative celiac disease, and the incidence of postoperative food choking were significantly lower in the MF group than that in the EH group. The increase of CRP, IL-6, IL-8, and TNF-α levels in the MF group was less than that in the EH group. CONCLUSIONS: The use of MF in robotic-assisted thoracoscopic radical lung cancer surgery is safe and effective, with advantages in lymph node dissection, reduced surgical trauma, and fewer postoperative complications.

Case Report: Diagnosis and Treatment of Two Clinical Cases of Visceral Leishmaniasis-Related Hemophagocytic Lymphohistiocytosis.

Visceral leishmaniasis-related hemophagocytic lymphohistiocytosis (VL-HLH) is a potentially life-threatening secondary hemophagocytic lymphocytic syndrome caused by protozoan parasites of the Leishmania species and transmitted by infected sandflies. Therefore, it is important to be highly vigilant of the infection, particularly the visceral subtype, to share information with the public health system, and to improve the early diagnosis rate so that appropriate treatment can be initiated promptly. We report two isolated cases of VL-HLH. The main clinical manifestations were fever, pancytopenia, splenomegaly, hypofibrinogenemia, and hyperferremia, which meet the HLH-2004 diagnostic criteria. In our experience, anti-HLH treatment was not very effective for either case. No Leishmania organism was found in the first bone marrow smear of either patient. The first patient was diagnosed after identification of Leishmania amastigotes via sternal bone marrow biopsy, rK39 immunochromatography test, and metagenomic next-generation sequencing. The other patient was diagnosed by rK39-rapid diagnostic test and polymerase chain reaction. However, because of the delayed diagnosis in both cases, their conditions continued to deteriorate and both patients eventually died of the disease. Leishmaniasis is a parasitic disease with regional specificity and a low incidence. The occurrence of secondary HLH has a great impact on prognosis. When encountering secondary HLH in clinical practice, leishmaniasis should remain on the list of differential causes. Because of a high mortality rate if diagnosed late, it is crucial to be vigilant of VL-HLH in practice so that early detection, diagnosis, and treatment of the disease can be achieved to reduce adverse patient outcomes.

Efficacy of using Maryland forceps versus electrocoagulation hooks in da Vinci robot-assisted thoracoscopic mediastinal tumor resection.

BACKGROUND: To compare the difference of short-term curative effect between the use of Maryland forceps (MF) and electrocoagulation hooks (EH) in da Vinci robot-assisted thoracoscopic mediastinal tumor resection. METHODS: Retrospectively analyze 84 patients with mediastinal tumors who underwent robot-assisted thoracoscopic surgery (RATS) at the Department of Thoracic Surgery in Gansu Provincial Hospital from February 2019 to February 2023. Two groups were divided according to the intraoperative use of energy devices, including 41 cases in the MF group and 43 cases in the EH group. Perioperative clinical data was gathered to compare the short-term efficacy of patients in both groups. RESULTS: There were no significant differences in baseline characteristics such as sex (P = 0.685), age (P = 0.165), and tumor size (P = 0.339) between the two groups. Compared with the EH group, patients in the MF group have shorter operative time (P = 0.030), less intraoperative bleeding (P = 0.010), less total postoperative drainage volume (P = 0.001), shorter postoperative drainage time (P = 0.022), shorter hospital stay (P = 0.019), and lower levels of interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-α), and cortisol. No statistically significant differences were found between the two groups in terms of total hospitalization costs (P = 0.123), postoperative visual analog scale (VAS) pain scores (P = 0.064), and postoperative complications (P = 0.431). CONCLUSION: Using MF in RATS for mediastinal tumor is safe and effective, which can reduce the amount of bleeding, reduce the degree of inflammatory reaction, and conducive to the quick recovery of patients.

Effects of da Vinci robot versus thoracoscopic surgery on body trauma and lymphocyte subsets in lung cancer patients: A propensity score matching study.

BACKGROUND: To assess the impact of da Vinci robot versus thoracoscopic surgery on body trauma and lymphocyte subsets in lung cancer patients. METHODS: Retrospective analysis of 352 patients with lung cancer treated by minimally invasive surgery completed by the same operator in the Department of Thoracic Surgery, Gansu Provincial People's Hospital from October 2019 to October 2022. According to the surgical procedure, the patients were divided into a robotic-assisted thoracic surgery (RATS) group (n = 159) and a video-assisted thoracoscopic surgery group (VATS) (n = 193), respectively. Propensity score matching (PSM) analysis was performed in both groups, and perioperative indicators were recorded. Levels of inflammatory markers (C-reactive protein, CRP; interleukin-6, IL-6) and lymphocyte subsets (CD3+ , CD4+ , CD8+ , and CD4+ /CD8+ ) were measured 1 day before surgery and 1, 3, and 5 days after surgery, respectively. To compare the effects of the two surgical procedures on the trauma and lymphocyte subsets of the patient's organism. RESULTS: One hundred and thirty-eight patients in each group after PSM. Compared with the VATS group, the RATS group had shorter operative time (p < 0.001), less intraoperative bleeding (p < 0.001), less postoperative chest drainage (p = 0.029), shorter postoperative chest drainage time (p = 0.008), and shorter postoperative hospital stay (p = 0.005). The levels of CRP and IL-6 increased in both groups after surgery compared with those before surgery, and the increase was less in the RATS group than that in the VATS group. Postoperative T-lymphocyte levels were lower in both groups compared with preoperative levels, and T-lymphocyte levels were significantly lower in the VATS group compared with the RATS group. CONCLUSION: Compared with VATS for treating lung cancer, RATS has advantages in short-term efficacy, and smaller surgical trauma to patients, which can reduce the body's inflammatory response. It also has less impact on T lymphocyte subpopulations, which can better protect patients' immune function.

Comparison of three-dimensional reconstruction and CT-guided Hook-wire segmental resection for pulmonary nodules: a propensity score matching study.

OBJECTIVE: To analyze and compare the clinical application value of three-dimensional reconstruction and computed tomography (CT)-guided Hook-wire localization for row lung segment resection of pulmonary nodules. METHODS: Retrospective analysis of the clinical data of 204 patients suffering from pulmonary nodules admitted to the Department of Thoracic Surgery of Gansu Provincial People's Hospital from June 2016 to December 2022. According to the preoperative positioning method, the group was divided into a 3D reconstruction group (98 cases) and a Hook-wire group (106 cases), respectively. The two groups of patients were propensity score matching (PSM) to compare their perioperative outcomes. RESULTS: All patients in both groups underwent successful surgeries without perioperative deaths. After PSM, 79 patients were successfully matched in each group. Two cases of pneumothorax, three cases of hemothorax, and four cases of decoupling occurred in the Hook-wire group; no complications of pneumothorax, hemothorax, and decoupling occurred in the 3D reconstruction group. Compared to the Hook-wire group, the 3D reconstruction group has shorter operative time (P = 0.001), less intraoperative bleeding (P < 0.001), less total postoperative chest drainage (P = 0.003), shorter postoperative tube placement time (P = 0.001), shorter postoperative hospital stay (P = 0.026), and postoperative complications (P = 0.035). There was no statistically significant difference between the two groups in terms of pathological type, TNM staging, and number of lymph node dissection. CONCLUSION: Three-dimensional reconstruction and localization of pulmonary nodules enables safe and effective individualized thoracoscopic anatomical lung segment resection with a low complication rate, which has good clinical application value.

Comparison of the efficacy of ETS with different segments for palmar, axillary and plantar hyperhidrosis.

BACKGROUND: To compare the near and long-term outcomes of endoscopic thoracic sympathectomy (ETS) for palmar, axillary and plantar hyperhidrosis. METHODS: We retrospectively analyzed the clinical data of 218 patients with hyperhidrosis who were admitted to the Department of Thoracic Surgery of Gansu Provincial People's Hospital for surgical treatment from April 2014 to August 2021. The patients were divided into three groups according to the method of ETS and the perioperative clinical data and postoperative follow-up data were collected to compare the near and long term outcomes of the three groups. RESULTS: There were 197 eligible patients at follow-up, 60 patients in the R4 cut-off group, 95 patients in the R3 + R4 cut-off group and 42 patients in the R4 + R5 cut-off group. There were no statistically significant differences in baseline indicators such as sex, age and positive family history among the three groups (P > 0.05). There was no statistically significant difference between the three groups in terms of operative time (P = 0.148), intraoperative bleeding (P = 0.308) and postoperative hospital stay (P = 0.407). Postoperatively, all three groups showed significant relief of palmar hyperhidrosis symptoms, with the R3 + R4 group having an advantage in terms of relief of axillary hyperhidrosis symptoms, patient satisfaction and quality of life index at 6 months postoperatively and the R4 + R5 group having an advantage in terms of relief of plantar hyperhidrosis symptoms. The difference in compensatory hyperhidrosis at 12 months postoperatively was not statistically significant among the three groups (P = 0.867), but the incidence was higher in the R3 + R4 and R4 + R5 groups than that in the R4 group. CONCLUSION: Patients with simple palmar hyperhidrosis can first consider R4 cut-off treatment; R3 + R4 cut-off is more effective in treating palmar hyperhidrosis combined with axillary hyperhidrosis; R4 + R5 cut-off is more effective in treating palmar hyperhidrosis combined with plantar hyperhidrosis. However, patients need to be informed that R3 + R4 and R4 + R5 dissection may increase the risk of severe compensatory hyperhidrosis after surgery.

A comparative study of robotic surgery and thoracoscopic surgery for mediastinal cysts.

OBJECTIVE: To compare the efficacy and safety of robotic-assisted thoracoscopic surgery (RATS) with video-assisted thoracoscopic surgery (VATS) in the treatment of mediastinal cysts. METHODS: Retrospective analysis on clinical data of 70 cases of minimally invasive surgery for mediastinal cysts completed in the Department of Thoracic Surgery, Gansu Provincial People's Hospital from April 2014 to December 2022. There were 34 cases in the RATS group with a cyst diameter of (3.70 ± 1.16) cm and 36 cases in the VATS group with a cyst diameter of (4.07 ± 1.20) cm. All cysts were evaluated preoperatively using magnetic resonance imaging (MRI) or chest computed tomography (CT) localization. Surgery-related indices were compared among the two groups. RESULTS: All patients in two groups successfully completed resection of mediastinal cysts without perioperative deaths. Compared with the VATS group, the RATS group possessed shorter operative time [(75.32 ± 17.80) min vs. (102.22 ± 19.80) min, P < 0.001], lesser intraoperative bleeding [10 (5.00, 26.00) ml vs. 17.50 (5.00, 50.50) ml, P = 0.009], shorter postoperative chest drainage time [2 (1.00, 6.00) ml vs. 3 (2.00, 6.50) ml, P = 0.006] and shorter postoperative hospital stay [3 (2.00, 6.50) d vs. 4 (3.00, 7.50) d, P = 0.001]. There was no statistically significant discrepancy in intermediate openings and complications in both groups (P > 0.05). CONCLUSION: Compared with VATS, RATS is safety and effectivity in the treatment of mediastinal cysts and thus has advantages in operative time, intraoperative bleeding, postoperative chest drainage time and postoperative hospital stay.

How information processing and risk/benefit perception affect COVID-19 vaccination intention of users in online health communities.

Objective: To investigate the relationship among information processing, risk/benefit perception and the COVID-19 vaccination intention of OHCs users with the heuristic-systematic model (HSM). Methods: This study conducted a cross-sectional questionnaire via an online survey among Chinese adults. A structural equation model (SEM) was used to examine the research hypotheses. Results: Systematic information processing positively influenced benefit perception, and heuristic information processing positively influenced risk perception. Benefit perception had a significant positive effect on users' vaccination intention. Risk perception had a negative impact on vaccination intention. Findings revealed that differences in information processing methods affect users' perceptions of risk and benefit, which decide their vaccination intention. Conclusion: Online health communities can provide more systematic cues and users should process information systematically to increase their perceived benefits, consequently increase their willingness to receive COVID-19 vaccine.
