ABSTRACT

Currently, there are limited studies assessing ChatGPT ability to provide appropriate responses to medical questions. Our study aims to evaluate ChatGPT adequacy in responding to questions regarding osteoporotic fracture prevention and medical science. We created a list of 25 questions based on the guidelines and our clinical experience. Additionally, we included 11 medical science questions from the journal Science. Three patients, 3 non-medical professionals, 3 specialist doctor and 3 scientists were involved to evaluate the accuracy and appropriateness of responses by ChatGPT3.5 on October 2, 2023. To simulate a consultation, an inquirer (either a patient or non-medical professional) would send their questions to a consultant (specialist doctor or scientist) via a website. The consultant would forward the questions to ChatGPT for answers, which would then be evaluated for accuracy and appropriateness by the consultant before being sent back to the inquirer via the website for further review. The primary outcome is the appropriate, inappropriate, and unreliable rate of ChatGPT responses as evaluated separately by the inquirer and consultant groups. Compared to orthopedic clinicians, the patients’ rating on the appropriateness of ChatGPT responses to the questions about osteoporotic fracture prevention was slightly higher, although the difference was not statistically significant (88% vs 80%, P = .70). For medical science questions, non-medical professionals and medical scientists rated similarly. In addition, the experts’ ratings on the appropriateness of ChatGPT responses to osteoporotic fracture prevention and to medical science questions were comparable. On the other hand, the patients perceived that the appropriateness of ChatGPT responses to osteoporotic fracture prevention questions was slightly higher than that to medical science questions (88% vs 72·7%, P = .34). ChatGPT is capable of providing comparable and appropriate responses to medical science questions, as well as to fracture prevention related issues. Both the inquirers seeking advice and the consultants providing advice recognize ChatGPT expertise in these areas.

ABSTRACT

BACKGROUND: The value of prophylactic closed-suction drainage in totally extraperitoneal inguinal hernia repair (TEP) is still a matter of controversy. We conducted a meta-analysis of studies examining postoperative seroma rates in patients with or without routine placement of closed-suction drainage tubes.

METHODS: A systematic literature search was conducted for trials comparing the outcome of TEP with or without routine drainage placement. Data regarding postoperative outcomes were extracted and compared by meta-analysis. The odds ratio and standardized mean differences with 95% confidence intervals were calculated.

RESULTS: Four studies were identified, involving a total of 1626 cases (Drain: n = 1251, no Drain: n = 375). There was a statistically significant difference noted between the 2 groups regarding postoperative seroma formation favoring the Drain group (odds ratio = 0.12; 95% confidence intervals [0.05, 0.29]; P < .001; 4 studies; I2 = 72%). For the remaining secondary endpoints postoperative urinary retention, recurrence, mesh infection and in-hospital length of stay no statistically significant difference was noted between the 2 study groups.

CONCLUSION: Current evidence suggests that patients who underwent TEP with routine closed-suction drain placement developed significantly fewer seromas without any additional morbidity or prolongation of in-hospital stay.

ABSTRACT

The coronavirus disease 2019 (COVID-19) outbreak caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) has affected various medical fields worldwide. However, relatively few studies have examined the impact of COVID-19 infection and vaccination on in vitro fertilization (IVF) outcomes and changes in SARS-CoV-2 antibody concentration in follicular fluid (FF). A total of 45 women were prospectively recruited and assigned to 3 groups: uninfected and non-vaccinated control group (Control group), infected group (COVID + group), and vaccinated group (Vaccination group). Serum and follicular fluid (FF) estradiol, progesterone, and SARS-CoV-2 antibody concentrations were measured. There were no statistical differences in the total number of retrieved oocytes (P = .291), mature oocytes (P = .416), and good-quality embryos (P = .694) among the 3 groups. In the vaccination group, BNT162b2 exhibited a significantly lower trigger-day serum estradiol/MII oocyte level (110.6 pg/mL) than other vaccines (289.5 pg/mL) (P = .006). No statistical differences in serum (P = .687) and FF (P = .108) SARS-CoV-2 antibody changes were noted among the 3 groups. Only FF antibody changes exhibited statistically significant differences between the BNT162b2 and other vaccine subgroups (P = .047). COVID-19 infection and vaccination do not affect IVF outcomes. However, the effect of BNT162b2 on steroidogenesis of the mature oocyte and FF SARS-CoV2 antibody titer should be further investigated.

ABSTRACT

BACKGROUND: Swallowing rehabilitation behavioral therapy and traditional Chinese acupuncture therapy are widely used in the treatment of post-stroke dysphagia (PSD). This study investigated the therapeutic effect of electro-acupuncture combined with exercise-based swallowing rehabilitation on PSD and its effect on brainstem auditory evoked potential (BAEP) and cerebral blood flow.

METHODS: The 120 PSD patients were divided into 2 groups (n = 60 each) by simple random grouping method, that is, an experimental and control group, receiving routine swallowing training, or additional intervention with electro-acupuncture at a frequency of 5 times/week. Data in swallowing function, BAEP, and cerebrovascular color Doppler ultrasound parameters were collected before treatment, as well as after treatment. An intergroup comparison was conducted using an independent sample t-test, and an intra-group comparison was conducted among different time points using a paired t-test. The data were analyzed using the SPSS Statistics 22.0 software; P < .05 was considered statistically significant.

RESULTS: The therapeutic effects were significantly better in the experimental group compared with the control group (P < .05). The standard swallowing function assessment scores were significantly lower in both groups after treatment (P < .05), and the score in the observation group was lower than in the control group (P < .05). The peak latency of BAEP waves III and IV, and the inter-peak latency between peaks III to V and I to V in the 2 groups changed significantly (P < .05). The peak systolic velocity (PSV), end-diastolic velocity (EDV), and mean velocity (MV) were significantly increased in both groups after treatment (P < .05). The pulsatility index decreased significantly in both groups (P < .05), and the PSV, EDV, and MV were higher in the experimental group than in the control group (P < .05).

CONCLUSION: Electro-acupuncture, combined with swallowing training in the treatment of Post-stroke Dysphagia, effectively improved cerebral microcirculation and conduction velocity, enhanced the motor function of swallowing muscles, and promoted the recovery of swallowing function.

ABSTRACT

BACKGROUND: Liraglutide widely utilized in type 2 diabetes treatment, has elicited conflicting findings regarding its impact on cardiac function in patients with this condition. Therefore, The objective of this study was to conduct a meta-analysis of randomized controlled trials (RCTs) to evaluate the effects of liraglutide on cardiac function in patients diagnosed with type 2 diabetes.

METHODS: We identified double-blind randomized trials assessing the effects of liraglutide compared to placebo on cardiac function in patients with type 2 diabetes. Data were synthesized with the fixed-effect models to generate standard mean differences (SMDs) with 95% confidence intervals (CIs) of each outcome for liraglutide versus placebo. The risk of bias would be assessed according to the Cochrane Risk of Bias Tool, while meta-analysis would be conducted using Revman 5.3.0 software. The evidence was graded based on the Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS: The meta-analysis encompassed 5 RCTs including 220 participants. Results revealed that liraglutide exhibited significant enhancements in left ventricular ejection fraction [SMD = -0.38, 95%CI(-0.70, -0.06), P = .02], cardiac index [SMD = -1.05, 95%CI(-1.52, -0.59), P < .0001], stroke volume [SMD = -0.67, 95%CI(-1.02, -0.32), P = .0002] and early diastolic filling velocity/late atrial filling velocity ratio [SMD = -0.52, 95%CI(-0.82, -0.22), P = .0006]. However, no statistically significant impact on cardiac output [SMD = -0.20, 95%CI(-0.53, 0.14), P = .26], early diastolic filling velocity/early diastolic annular velocity (E/Ea) ratio [SMD = -0.34, 95%CI(-0.75, 0.06), P = .10] and early diastolic filling velocity/early diastolic mitral annular velocity ratio [SMD = 0.21, 95%CI(-0.15, 0.56), P = .25] was observed. The Grading of Recommendations Assessment, Development and Evaluation evidence quality ratings indicated that all the outcome measures included in this study were evaluated as having low and very low quality.

CONCLUSION: The available evidence suggested that liraglutide may exert a favorable impact on cardiac function in patients with type 2 diabetes. Consequently, the utilization of liraglutide as a preventive measure against heart failure incidents in individuals with type 2 diabetes represents a promising strategy. However, robust evidence support requires the conduct of large-scale, multicenter high-quality RCTs.

ABSTRACT

This study aimed to develop nomograms to accurately predict the overall survival (OS) and cancer-specific survival (CSS) of non-metastatic bladder cancer (BC) patients. Clinicopathological information of 260,412 non-metastatic BC patients was downloaded from the Surveillance, Epidemiology, and End Results (SEER) database from 2000 to 2020. LASSO method and Cox proportional hazard regression analysis were utilized to discover the independent risk factors, which were used to develop nomograms. The accuracy and discrimination of models were tested by the consistency index (C-index), the area under the subject operating characteristic curve (AUC) and the calibration curve. Decision curve analysis (DCA) was used to test the clinical value of nomograms compared with the TNM staging system. Nomograms predicting OS and CSS were constructed after identifying independent prognostic factors. The C-index of the training, internal validation and external validation cohort for OS was 0.722 (95%CI: 0.720-0.724), 0.723 (95%CI: 0.721-0.725) and 0.744 (95%CI: 0.677-0.811). The C-index of the training, internal validation and external validation cohort for CSS was 0.794 (95%CI: 0.792-0.796), 0.793 (95%CI: 0.789-0.797) and 0.879 (95%CI: 0.814-0.944). The AUC and the calibration curves showed good accuracy and discriminability. The DCA showed favorable clinical potential value of nomograms. Kaplan-Meier curve and log-rank test uncovered statistically significance survival difference between high- and low-risk groups. We developed nomograms to predict OS and CSS for non-metastatic BC patients. The models have been internally and externally validated with accuracy and discrimination and can assist clinicians to make better clinical decisions.

ABSTRACT

This study aimed to analyze the composition of the total hospitalization expenses of patients with lung cancer in Beijing TongRen Hospital from January 2018 to December 2020 before and after the implementation of the “Beijing Medical Consumption Linkage Comprehensive Reform Implementation Plan” (hereinafter referred to as “Reform”). The SPSS 25.0 statistical software was used to perform descriptive statistics on the total hospitalization costs of selected 1517 patients with lung malignant tumors, and single factor and multivariate regression analysis were used to clarify the influencing factors of the patients’ total hospitalization costs. From 2018 to 2020, the total hospitalization costs of patients with lung malignant tumors increased year by year (P < .05), and the average length of hospital stay decreased year by year (P < .05). The total hospitalization expenses of patients with lung malignant tumors mainly include material expenses, surgical expenses, inspection expenses, inspection expenses and medicine expenses. After the implementation of the “Reform,” the proportion of medicine, inspection, nursing and other expenses in the total hospitalization expenses of patients with lung malignant tumors has been significantly reduced (P < .05), and the proportion of surgical expenses has been significantly increased (P < .05). The results of the univariate analysis showed that gender, age, length of stay in the hospital, surgery, and tumor location were the main factors affecting the total hospitalization expenses of patients (P < .05). The results of multivariate analysis showed that gender (female), age (<40 years old), length of stay (≥15 days), surgery (yes), and tumor location (right lung) are the main factors affecting the total hospitalization cost of patients with malignant tumors (P < .05). Under the premise of ensuring the efficacy of patients, the economic burden of patients is reduced by reducing the cost of materials, shortening the length of hospitalization, strengthening hospital management, and controlling the continuous growth of hospitalization costs.

ABSTRACT

The objective of this study is to investigate the value of early pregnancy ultrasound combined with ultrasound score (USS) for the evaluation of placenta accreta (PA) in scar uteri. Thirty cases of PA in scar uteri diagnosed by ultrasound at our hospital between June 2021 and June 2022 were selected retrospectively (observation group). In addition, 30 patients had placenta attached to the anterior wall of the uterus and covered the internal orifice of the cervix; however, no PA was selected in the same period (control group). The results of surgical pathology and ultrasound examination in the first trimester of pregnancy (11-14 weeks of pregnancy, fetal top hip length 4.5-8.4 cm) were analyzed. Ultrasonic image characteristics of the 2 groups were scored using an ultrasonic scoring scale. The ultrasonic signs and ultrasonic scores of the 2 groups were analyzed. The diagnostic value of ultrasound and USS for PA in the scarred uterus alone and in combination was analyzed based on the gold standard of surgical and pathological results. The rich blood flow signal at the junction of the uterine serosa and bladder, the rate of blood flow in the cavity of the placental parenchyma, the thinning rate of the myometrium after placenta, and the abnormal rate of the low echo area after placenta in the observation group were significantly higher than those in the control group (P < .05). The USS of the observation group was significantly higher than that of the control group (P < .05). The sensitivity (93.33%) and accuracy (95.00%) of the combined examinations were significantly higher than those of ultrasound (70.00% and 83.33%, respectively) (P < .05). The sensitivity and accuracy of combined examination were slightly higher than those of USS examination (83.33% and 90.00%), but the difference was not statistically significant (P > .05). There was no significant difference between the specificity of combined examination (93.33%) and ultrasound (96.67%) and USS (96.67%) (P > .05). Early pregnancy ultrasound and USS evaluation have high application value in the diagnosis and evaluation of early scar uterine PA. The combination of the 2 methods can further improve the sensitivity and accuracy of diagnosis.

ABSTRACT

This study is an observation of the early screening and treatment effect of infant developmental dysplasia of the hip (DDH) in an area in China. From January 2016 to December 2017, we selected infants and toddlers with high-risk factors for DDH, such as asymmetric gluteal folds, unequal length of lower limbs, and limited hip joint abduction, who visited the Department of Child Health Care and the Outpatient Clinic of Pediatric Orthopedics at the Affiliated Hospital of Zunyi Medical University. In total, 1485 cases were divided into age groups, examined using Graf ultrasound and X-ray, and the results were analyzed. Meanwhile, early interventions were actively adopted for cases with abnormalities during the screening. The detection rates of DDH were 24.0%, 2.8%, 9.3%, and 12.2% among those with 0 to 6 months, 7 to 12 months, 13 to 18 months, and 19 to 24 months of age, respectively. Early and individualized corrective conservative treatment was considered for children with abnormalities, and the cure rates were 87.0%, 65.7%, 41.0%, and 16.7% among those with 0 to 6 months, 7 to 12 months, 13 to 18 months, and 19 to 24 months of age, respectively. There was a statistically significant difference in the detection and cure rates of DDH in infants and toddlers of different ages (P < .01).

ABSTRACT

The study aimed to determine the optimal entry points and trajectories for posterior subaxial cervical pedicle screw (CPS) fixation. Computed tomography (CT) and Mimics software were used to evaluate the subaxial cervical pedicle in 42 cervical spine CT scans. The width of the cervical pedicle was measured and compared at medial angulations of 30°, 35°, 40°, 45°, 50°, 55°, and 60° relative to the midline sagittal plane. Based on an observational examination of the positions of all cervical 3-dimensional models and screws, the proposed entry point for C3-7 CPS was analyzed. Although the variations in C3-6 pedicle width (PW) among 45°, 50°, and 55° were not statistically significant, they were significantly larger than the differences among 30°, 35°, 40°, and 60° angles (P < .05). The differences in C7 PW between the 30°, 35°, 40°, and 45° angles were not statistically different even though the 30°, 35°, 40°, and 45° angles were significantly bigger. (P < .05). The proposed entry point for C3-7 CPS was below the junction of the lateral and lower borders of the superior articular process joint surface. The entry point for C3-7 levels was below the junction of the lateral and lower borders of the superior articular process joint surface. The optimal medial angulation for the posterior C3-6 CPS was 45°-55° and that for the posterior C7 CPS was 30°-45°. The sagittal angle of the posterior C3-7 CPS was parallel to the corresponding upper endplate.
