Objective:To evaluate direct and indirect costs for schizophrenia,major depressive disorder(MDD)and bipolar disorder,and to compare their differences of cost composition,and to explore the drivers of the total costs.Methods:A total of 3 175 inpatients with schizophrenia,MDD,and bipolar disorder were recruited.In-patient's self-report total direct of medical costs outpatient and inpatient,out-of-pocket costs,and direct non-medical costs were regarded as direct costs.Productivity loss and other loss caused by damaging properties were defined as indirect costs.The perspectives of this study included individual and societal levels.Multivariate regression analysis was applied for detecting the factors influencing disease costs.Results:The total cost of schizophrenia was higher than those of MDD and bipolar disorder at individual and societal levels.The indirect costs of three mental disorders were higher than the direct costs,and the indirect cost ratio of bipolar disorder was higher than those of schizophre-nia and MDD.Age,gender,working condition and marital status(P＜0.05)were the important drivers of total costs.Conclusion:The economic burden of the three mental disorders is relatively heavy.Schizophrenia has heaviest disease burden,and the productivity loss due to mental disorders is the driving force of the soaring disease cost

Background::In vitro fertilization (IVF) has emerged as a transformative solution for infertility. However, achieving favorable live-birth outcomes remains challenging. Current clinical IVF practices in IVF involve the collection of heterogeneous embryo data through diverse methods, including static images and temporal videos. However, traditional embryo selection methods, primarily reliant on visual inspection of morphology, exhibit variability and are contingent on the experience of practitioners. Therefore, an automated system that can evaluate heterogeneous embryo data to predict the final outcomes of live births is highly desirable. Methods::We employed artificial intelligence (AI) for embryo morphological grading, blastocyst embryo selection, aneuploidy prediction, and final live-birth outcome prediction. We developed and validated the AI models using multitask learning for embryo morphological assessment, including pronucleus type on day 1 and the number of blastomeres, asymmetry, and fragmentation of blastomeres on day 3, using 19,201 embryo photographs from 8271 patients. A neural network was trained on embryo and clinical metadata to identify good-quality embryos for implantation on day 3 or day 5, and predict live-birth outcomes. Additionally, a 3D convolutional neural network was trained on 418 time-lapse videos of preimplantation genetic testing (PGT)-based ploidy outcomes for the prediction of aneuploidy and consequent live-birth outcomes.Results::These two approaches enabled us to automatically assess the implantation potential. By combining embryo and maternal metrics in an ensemble AI model, we evaluated live-birth outcomes in a prospective cohort that achieved higher accuracy than experienced embryologists (46.1% vs. 30.7% on day 3, 55.0% vs. 40.7% on day 5). Our results demonstrate the potential for AI-based selection of embryos based on characteristics beyond the observational abilities of human clinicians (area under the curve: 0.769, 95% confidence interval: 0.709–0.820). These findings could potentially provide a noninvasive, high-throughput, and low-cost screening tool to facilitate embryo selection and achieve better outcomes. Conclusions::Our study underscores the AI model’s ability to provide interpretable evidence for clinicians in assisted reproduction, highlighting its potential as a noninvasive, efficient, and cost-effective tool for improved embryo selection and enhanced IVF outcomes. The convergence of cutting-edge technology and reproductive medicine has opened new avenues for addressing infertility challenges and optimizing IVF success rates.

As one of the important contents and links of doctor-patient communication, the quality of breaking bad news will affect the development of doctor-patient relationship. Bad news informed not only involves the feedback of clinical medical diagnosis results, but also involves special knowledge training and clinical experience accumulation, as well as ethical, legal, social custom and other factors. At present, it is still a difficult problem troubling physicians in the medical environment. From the different perspectives of doctors, patients and family members, this paper sorted out the domestic and international status of breaking bad news, revealed its internal dilemmas, and summarized the informing strategies to cope with these dilemmas, with a view to providing references for hospital managers and medical staff to earlier identify and properly inform, helping both doctors and patients to get rid of the dilemma of notification and improve the doctor-patient relationship.

Objective To evaluate the value of chromosomal microarray analysis (CMA) for genetic evaluation of fetal ultrasound abnormality. Methods A total of 180 pregnant women with fetal abnormality detected by prenatal ultrasound diagnosis in the first trimester during the period from January 2020 through May 2022 were enrolled as the study subjects. All prenatal fetal screening samples were subjected to G-band karyotyping and CMA. Results G-band karyotyping detected normal karyotypes in 168 samples (93.85%) and abnormal karyotypes in 11 samples (6.15%), and CMA detected 17 positive samples (9.44%) and 163 negative samples (90.56%). The seventeen positive samples included 11 pathogenic copy number variations (CNVs) and 6 variants of unknown significance (VOUS), and there were 11 CMA-positive results consistent with G-band karyotyping, and 6 additional pathogenic CNVs mainly included microdeletion and microduplication syndromes. The detection rates of pathogenic CNVs were 11.11%, 2.63%, 2.78%, 4.00%, 0, 0, 11.11% and 0 among the fetuses with abnormal structure of the cardiovascular system, the lymphatic system, the nervous system, the digestive system, the cranial and face system, the skeletal system, the urinary system, and other system (χ² =8.188, P = 0.316). All eleven fetuses with pathogenic CNVs detected by CMA were all induced for abortion. Conclusion CMA improves the detection of genetic abnormality among fetuses with ultrasound abnormality in relative to G-band karyotyping, which is feasible for prenatal cytogenetic diagnosis among fetuses with ultrasound abnormality

The patients were grouped according to the course of disease, the incidences of tophus in patients with course of disease ≤5.0 years, 5.1 to 10.0 years and >10.0 years were 15.34% (50/326), 27.67% (44/159) and 48.45% (78/161), and there was statistical difference ( χ2 = 60.59, P<0.01); the patients were grouped according to the quartiles of serum uric acid, the incidences of tophus in patients with serum uric acid <424.05 μmol/L, 424.05 to 505.24 μmol/L, 505.25 to 576.17 μmol/L and ≥576.18 μmol/L were 14.91% (24/161), 32.72% (53/162), 29.01% (47/162) and 29.81% (48/161), and there was statistical difference ( χ2 = 15.70, P<0.01). Binary Logistic regression analysis result showed that the course of gout, smoking amount, number of joint involved in attack, serum uric acid and LDL-C were the independent risk factors of subcutaneous tophus among hospitalized gout patients ( OR = 1.069, 1.020, 1.317, 1.002 and 1.262; 95% CI 1.032 to 1.097, 1.006 to 1.032, 1.223 to 1.417, 1.000 to 1.003 and 1.033 to 1.541; P<0.01 or <0.05). Conclusions:The duration of disease, number of involved joint, serum uric acid level, unhealthy lifestyles and lipid metabolism disorders are the independent risk factors of subcutaneous tophus among hospitalized gout patients.

Objective:To investigate the correlation between serum uric acid levels and thyroid hormones in hospitalized elderly gout patients.Methods:A total of 646 hospitalized gout patients, including 616 males and 30 females, aged(68.8±5.1)years, who were hospitalized at the Department of Gout, Chu Hsien-I Memorial Hospital from April 2014 to December 2019, were retrospectively analyzed.Clinical information was collected and relevant biochemical tests were conducted.Serum uric acid (SUA)levels were divided into quartiles and their associations with thyroid hormone levels were analyzed.Results:With the increase of SUA, body mass index, the prevalence of obesity, the prevalence of dyslipidemia, and the prevalence of fatty liver, the number of involved joints, cholesterol, low-density lipoprotein cholesterol, triacylglycerol, and homeostasis model assessment trended upward significantly( P<0.05); FUA showed a downward trend( F=9.42, P>0.05). The prevalence of subclinical hypothyroidism in older patients was 11.3%(73 cases). With the increase of SUA, the prevalence of subclinical hypothyroidism and free triiodothyronine levels showed an upward trend, whereas free thyroxine levels showed a downward trend( P<0.01). Conclusions:In elderly gout patients, the prevalence of subclinical hypothyroidism increases with SUA levels.Hyperuricemia and multiple metabolic disorders are independent risk factors for subclinical hypothyroidism in these patients.

Objective:To study the therapeutic effect and mechanism of autologous platelet-rich plasma (PRP) on rabbit traumatic optic neuropathies (TON) and retina.Methods:Forty adult New Zealand white rabbits were selected to establish the optic nerve clamp injury model in their right eyes.According to the random number table method, 36 New Zealand white rabbits with effective model were randomly divided into model control group, normal saline control group and PRP group, 12 for each group.Another 12 healthy rabbits served as the normal control group.Rabbit autologous blood was collected to prepare PRP.The retrobulbar 20 μl PRP/20 μl saline solution injection was administered every two days near the injury after modeling according to grouping.The injection was carried out for 10 times.There was no other interference administrated to the model control group except the normal anti-infective treatment.No interference was given to the normal control group.At 30 and 60 days after modeling, the eyeballs and optic nerves of right eyes were harvested through sacrificing the animals by anesthetic overdose, three eyes for each time.Histopathological assessments were performed to observe the morphological changes of retina and optic nerve, and to evaluate the changes of retinal ganglion cells (RGCs) density and retinal nerve fiber layer (RNFL) thickness.Immunohistochemistry was used to assess the expressions of apoptosis factors caspase-3 and B cell lymphoma-2(Bcl-2). Quantitative real-time PCR and Western blot were used to detect the mRNA and protein expressions of brain-derived neurotrophic factor (BDNF) and growth associated protein-43 (Gap-43). This study protocol was approved by the Experimental Animal Ethics Committee of Wuhan University (No.E2019072805). The use and care of animals complied with ARVO statement.Results:The thickness of RNFL and number of RGCs at 30 days and 60 days after modeling were (6.60±1.16) μm, (6.89±1.21) μm, (13.00±1.00)/field of vision, (20.00±2.65)/field of vision in the PRP group, respectively, and were (4.80±0.43)μm, (2.18±0.23)μm, (6.33±0.58)/field of vision, (10.33±1.53)/field of vision in the model control group, respectively.The number of RGCs in the PRP group at 60 days was higher than that at 30 days after modeling, the number of RGCs in the PRP group was higher than that in the model control group, the thickness of RNFL in the PRP group was higher than that in the model control group; and the differences were statistically significant (all at P<0.05). At 30 and 60 days after modeling, the positive expression A value of caspase-3 protein in the normal saline group and model control group were higher than those in the normal control group and PRP group, while the positive expression A value of Bcl-2 protein in the PRP group was higher than those in the model control group and normal saline group, and the differences were statistically significant (all at P<0.05). The mRNA level and protein content of BDNF and Gap-43 in the retina and optic nerves at 30 days and 60 days after modeling in the PRP group were higher than those in the model control group, and the differences were statistically significant (all at P<0.05), but the mRNA and protein expression levels of BDNF and Gap-43 in different tissues in the PRP group at 60 days after modeling were lower than those at 30 days after modeling ( P<0.05). Conclusions:PRP can effectively inhibit the apoptosis of RGCs and the secondary injury of the retina after optic nerve injury, promote cell anti-apoptosis effect of RGCs, thereby retard the damage of the retina and optic nerve after TON, and also promote the repair of optic nerve and retina through upregulating the expression of nerve growth factors.

Objectives:To analyze the prevalence and risk factors of chronic nephropathy among hospitalized gout patients.Methods:537 hospitalized gout patients in Tianjin Medical University Chu Hsien-I Memorial Hospital were enrolled. According to the levels of glomerular filtration rate (eGFR>90 ml/min, 60-90 ml/min and <60 ml/min), patients were divided into normal group, mild chronic nephropathy group and moderate-severe chronic nephropathy group. The height, weight, waist, hip and blood pressure of the patients were measured. Blood samples from elbow vein were collected to measure biochemical indexes. The 24-hour urine was collected to measure creatinine and uric acid. Multivariate regression analysis was used to analyze the related factors that may affect eGFR.Results:The prevalence of chronic nephropathy among gout patients was 46.76%(251/537), which the prevalence of mild chronic nephropathy was 34.82%(187/537), and moderate severe chronic nephropathy was 11.92%(64/537). With the decline of eGFR, the older the patients, the longer the course of gout and hypertension, the more the number of joints involved, the higher the blood uric acid, urinary microalbumin, urinary protein, white blood cell count, uric acid excretion fraction (FeUA), and the lower the red blood cell count, hemoglobin and serum albumin. Pearson correlation analysis of eGFR showed that age, duration of gout and hypertension, number of involved joints, hemoglobin, serum albumin, serum uric acid, urinary microalbumin, and FeUA were correlated with eGFR ( r=-0.43, -0.238, -0.25, -0.128, 0.155, 0.138, -0.169, -0.29, -0.372, respectively, P<0.01). Multivariate regression analysis showed that age, the course of gout, serum uric acid, microalbuminuria and FeUA were independent risk factors for eGFR decline ( P<0.01). Conclusions:Eldly, long course of gout, poor control of serum uric acid and increased excretion of uric acid and microalbumin are risk factors of gout.

Objective:To investigate the association between age and cardiac tamponade after radiofrequency ablation of atrial fibrillation(RAAF).Methods:Clinical data of patients undergone de novo AF ablation procedures at Beijing Anzhen Hospital from January 2013 to December 2016 were retrospectively collected.Patients were divided into an elderly group(age ≥60 years)and a non-elderly group(age <60 years). Logistic regression analyses were used to evaluate the association between old age and the risk of cardiac tamponade complicating RAAF.Results:A total of 5 313 patients were involved in this study, including 41 patients(0.77%)with cardiac tamponade.The proportion of cardiac tamponade was higher in the elderly group than in the non-elderly group(1.1% or 32/2 950 vs.0.4% or 9/2 363, χ2=8.489, P=0.004). One patient with cardiac tamponade in the elderly group required immediate surgical repair whereas none in the non-elderly group did.No patient died in hospital.Multivariate Logistic regression analysis showed that the risk of cardiac tamponade increased in the elderly group, compared with the non-elderly group( OR=2.570, 95% CI: 1.190-5.570, P=0.017). Stratified analysis revealed that among females and patients with oral anticoagulants, left atrium dimension < 40 mm or procedure duration≥ 120 min in the elderly group carried a higher risk of cardiac tamponade than those in the non-elderly group( OR=1.011, 2.914, 3.922 and 3.244, P<0.05). Conclusions:Old age(age ≥60 years)is an independent risk factor for cardiac tamponade complicating RAAF.

Four hundred and four male patients with primary gout were enrolled. According to the degree of nonalcoholic fatty liver diseases (NAFLD), the patients were divided into simple gout ( n=121), gout combined with mild NAFLD ( n=149) and gout combined with moderate-severe NAFLD ( n=134). The height, weight, waist, hip, blood pressure and blood biochemistry parameters of patients were measured. The degree of NAFLD was negatively correlated with the age of patients in three groups. The BMI, ratio of waist/hip, count of red cells, hemoglobin, hematocrit, red blood cell distribution width ( SD and CV), triglyceride, alanine aminotransferase and HOMA-IR were increased with the increasing of NAFLD severity (all P<0.05). Red blood cell count, hemoglobin, alanine aminotransferase, serum uric acid increased with the increasing of NAFLD severity (all P<0.05). Platelet, serum urea nitrogen and serum creatinine were decreased with the increase of NAFLD severity. Logistic regression showed that BMI, hemoglobin and HOMA-IR were independent risk factors for NAFLD. The prevalence and the severity of NAFLD was increased with increasing quadrates of hemoglobin. Taking group Q1 as a control, OR of NAFLD in group Q2 was 1.166(95 %CI:0.638-2.133), OR in group Q3 was 2.011(95 %CI:1.122-3.605)and OR in group Q4 was 3.120(95 %CI:1.613-6.034). The result indicates that hemoglobin levels are associated with the development and the severity of NAFLD in male patients with primary gout.
