Características clínicas y evolutivas de adenomas hipofisarios incidentales: estudio multicéntrico retrospectivo / Clinical and evolutionary characteristics of incidental pituitary adenomas: retrospective multicenter study

Resumen Introducción : Los incidentalomas hipofisarios (IH) son lesiones halladas fortuitamente en la hipófisis mediante imágenes realizadas por motivos no relacionados con enfermedad hipofisaria. Métodos : Se realizó un estudio transversal, retros pectivo y descriptivo con el objetivo de analizar las características clínicas y evolutivas de una población de pacientes portadores de IH en la ciudad de Córdoba. Resultados : Se incluyeron 67 pacientes, 67% del sexo femenino, con una mediana de edad al diagnóstico de 44 años. Entre los motivos que llevaron a solicitar la primera imagen, la cefalea crónica o recurrente fue el más prevalente (34%). La mediana del tamaño tumoral fue de 12 mm. El 58% fueron macroincidentalomas. Los hombres tuvieron lesiones significativamente más grandes (p = 0.04). Al diagnóstico, considerando ambos sexos, el 30% evidenció extensión extraselar y el 45% invasión a senos cavernosos. Se detectó compromi so neurooftalmológico en el 21%. Se halló correlación positiva entre la edad al momento del diagnóstico y el tamaño tumoral (r = +0.31, p = 0.001). El 91% fueron tumores no funcionantes y en su presentación, el 21% de los pacientes presentaron una o más deficiencias hormonales. El 26% del total requirió cirugía. La ma yoría de aquellos que continuaron sin tratamiento no evidenciaron cambios en el tamaño tumoral al final del seguimiento (mediana 42 meses). Conclusión : Destacamos la elevada frecuencia de macroincidentalomas en nuestra serie, siendo los de fectos del campo visual y el hipopituitarismo frecuentes al diagnóstico. Si bien la mayoría de los IH no operados permanecieron estables, existió una alta frecuencia de lesiones clínicamente significativas.

Abstract Introduction : Pituitary incidentalomas (PIs) are le sions found incidentally in the pituitary on imaging performed for reasons unrelated to pituitary disease. Methods : A cross-sectional, retrospective and descrip tive study was carried out with the aim of analyzing the clinical and evolutionary characteristics of a population of patients with PIs in the city of Córdoba. Results : A total of 67 patients were included, 67% fe male, with a median age at diagnosis of 44 years. Among the reasons that led to requesting the first image, chron ic or recurrent headache was the most prevalent (34%). The median tumor size was 12 mm. Fifty-eight percent were macroincidentalomas. Men had significantly larger lesions (p = 0.04). At diagnosis, including both sexes, 30% showed extrasellar extension and 45% invasion of the cavernous sinuses. Neuro-ophthalmological compromise was detected in 21%. A positive correlation was found between age at diagnosis and tumor size (r= +0.31, p = 0.001). Ninety-one percent were non-functioning tumors and at presentation, 21% of patients had one or more hormonal deficiencies. Of the total, 26% required surgery. Most of those who continued without treatment showed no change in tumor size at the end of follow-up (median 42 months). Conclusion : We highlight the high frequency of mac roincidentalomas in our series, with visual field defects and hypopituitarism being frequent at diagnosis. Al though most non-operated PIs remained stable, there was a high frequency of clinically significant lesions.

Gravidade da depressão, resposta ao tratamento e PRO (incapacidade e QoL) em pacientes com DRT em um ano de acompanhamento com tratamento padrão: análise do subgrupo brasileiro do estudo observacional multinacional TRAL / Depression severity, treatment response and PRO (disability and QoL) in TRD patients over a 1-year follow-up with standard of care: Analysis of the Brazilian subset of the multicenter, observational TRAL study

Objetivo: A depressão resistente ao tratamento (DRT) é uma preocupação primária no Brasil devido à sua natureza onerosa e complexa, enquanto o diagnóstico e o tratamento geralmente são desafiadores. O presente manuscrito apresenta os resultados clínicos de um ano de acompanhamento em pacientes com DRT em tratamento padrão (SOC) no subgrupo brasileiro do estudo de Depressão Resistente ao Tratamento na América Latina (TRAL). Métodos: Essa fase longitudinal do estudo TRAL tinha como meta caracterizar alterações nos resultados clínicos e outras variáveis de interesse (p. ex., qualidade de vida, incapacidade) em um ano de acompanhamento em pacientes com DRT em 10 centros no Brasil. Os pacientes incluídos tinham diagnóstico clínico de DRT com base nos critérios DSM-5 e confirmado por MINI. A Escala de Depressão de Montgomery-Asberg (MADRS) era usada para avaliar a gravidade da doença e os resultados clínicos. Outras escalas de depressão e instrumentos classificados pelo paciente eram usadas para medir resultados correlacionados. Resultados: Cento e cinquenta e oito pacientes com DRT, na maioria mulheres (84,4%) com idade média de 48,55 anos, foram incluídos na análise. Apenas 31,4% dos pacientes apresentaram uma resposta clinicamente significativa, 10,3% tiveram recidiva e 26,7% alcançaram remissão, conforme medido pela MADRS no final do estudo (EOS). Aproximadamente 55% dos pacientes apresentavam depressão grave/moderadamente grave no EOS. Problemas de mobilidade, cuidados pessoais, problemas nas atividades usuais e dor e desconforto foram relatados pela maioria dos pacientes no EOS, assim como comprometimento marcado/extremo das atividades no trabalho/escola e da vida social/das atividades de lazer no EOS. Conclusões: Os resultados clínicos alcançados atualmente ainda são notavelmente insatisfatórios para DRT. Portanto, o envolvimento de todas as partes interessadas é essencial para implementar protocolos de tratamento mais eficazes no Brasil.

Objective: Treatment-resistant depression (TRD) is a primary concern in Brazil due to its burdensome and complex nature, while diagnosis and treatment is often challenging. The current manuscript presents the clinical outcomes in a one-year follow-up of TRD patients under Standard-of-care (SOC) in the Brazilian subset of the Treatment-Resistant Depression in America Latina (TRAL) study. Methods: This longitudinal phase of TRAL aimed to characterize changes in the clinical outcomes and other variables of interest (e.g. quality of life, disability) in a one-year follow-up of TRD patients in 10 centers in Brazil. Included patients were clinically diagnosed with TRD based on DSM-5 criteria and confirmed by MINI. Montgomery-Asberg Depression Rating Scale (MADRS) was used to assess disease severity and clinical outcomes. Other depression scales and patient rated instruments were used to measure correlated outcomes. Results: One hundred fifty-eight TRD patients, mostly female (84.4%), averaging 48.55 years, were included in the analysis. Only 31.4% of the patients showed a clinically significant response, 10.3% had a relapse and 26.7% achieved remission, as measured through MADRS at end-of-study (EOS). Almost 55% of the patients showed moderately severe/severe depression at EOS. Mobility issues, self-care, problems with usual activities and pain and discomfort were reported by the majority of the patients at EOS, as well as marked/extreme disruption of school/work and social life/leisure activities at EOS. Conclusions: Currently achieved clinical outcomes are still remarkably unsatisfactory for TRD. Therefore, the involvement of all relevant stakeholders is essential to implement more effective treatment protocols in Brazil.

Surgical outcome and safety of peripheral iridectomy plus goniosynechialysis and goniotomy in the treatment of advanced primary angle-closure glaucoma / 中华实验眼科杂志

Objective:To evaluate the preliminary effectiveness and safety of surgical peripheral iridectomy (SPI) combined with goniosynechilysis (GSL) and goniotomy (GT) in the treatment of advanced primary angle-closure glaucoma (PACG).Methods:A multicenter observational case series study was performed.Thirty-five eyes of 27 patients with advanced PACG, who underwent SPI+ GSL+ GT with a follow-up of at least 6 months, were included from August 2021 to January 2022 at Zhongshan Ophthalmic Center, Handan City Eye Hospital, Shijiazhuang People's Hospital, West China Hospital of Sichuan University, and the Third Affiliated Hospital of Chongqing Medical University.The mean follow-up time was 9(7, 10) months.Pre- and post-operative best corrected visual acuity (BCVA) and intraocular pressure (IOP) were measured with an ETDRS chart and a Goldmann applanation tonometer, respectively.The number of anti-glaucoma medications applied before and after surgery was recorded, and the complications after surgery were analyzed.Success rate of surgery was calculated.Complete surgical success was defined as an IOP of 5-18 mmHg (1 mmHg=0.133 kPa) and 20% reduction from baseline without anti-glaucoma medication or reoperation.Qualified success was defined as achieving criterion of complete success under anti-glaucoma medications.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-sen University (No.2021KYPJ177). Written informed consent was obtained from each subject.Results:The mean preoperative IOP was (30.83±8.87)mmHg, which was significantly decreased to (15.69±3.70)mmHg at 6 months after the surgery ( t=8.588, P<0.001), with a 44.00% (34.78%, 60.00%) decline of 13.00(8.00, 21.00)mmHg.The median number of anti-glaucoma medications was significantly reduced from 2(0, 3) preoperatively to 0 (0, 1) postoperatively ( Z=-3.659, P<0.001). The mean preoperative and postoperative 6-month BCVA were 0.80(0.63, 1.00) and 0.80(0.60, 1.00), respectively, showing no significant difference ( Z=-0.283, P=0.777). Complete surgical success rate was 62.86%(22/35), and the qualified success rate was 91.43%(32/35). Surgical complications mainly included hyphema (6/35), IOP spike (3/35), and shallow anterior chamber (4/35). There was no vision-threatening complication. Conclusions:SPI+ GSL+ GT is preliminarily effective and safe in the treatment of advanced PACG, which provides a new option for PACG.

Risk factors for neonatal asphyxia and establishment of a nomogram model for predicting neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture: a multicenter study / 中国当代儿科杂志

OBJECTIVES@#To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia.@*METHODS@#A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively.@*RESULTS@#Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia.@*CONCLUSIONS@#The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

The safety and efficacy of radiofrequency in the treatment of overactive bladder / 中华泌尿外科杂志

Objective:To explore the safety and efficacy of radiofrequency in the treatment of overactive bladder(OAB).Methods:A prospective, multicenter, non-randomized controlled trial was conducted. Eligible patients were divided into test group and control group in Zhejiang Provincial People’Hospital, The First Affiliated Hospital of Wenzhou Medical University, and Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine from March 2019 to June 2020. Inclusion criteria: patients diagnosed with OAB, and bladder capacity>100ml. Exclusion criteria: pregnant and lactating women; patients with secondary OAB symptoms such as urinary tract obstruction; patients with uncontrolled urinary tract infection within 1 week; patients in stable stage by using other treatment methods; patients implanted with any nerve stimulator, cardiac pacemaker or implantable defibrillator; patients with malignant tumors, serious cardiovascular, cerebrovascular diseases, renal insufficiency or received BTX treatment in recent 12 months. The patients were allocated to test group and the control group in a ratio of 2∶1 according to the time sequence of the visit. The patients in the test group were treated with radiofrequency treatment. After entering the group, they were treated for 4 times at the 1st, 2nd, 7th and 8th week respectively. In the control group, the energy was turned off during the radiofrequency treatment. The patients were followed-up every week until the end of the 12th week. The treatment success rate [the average frequency of urination in 24 h was reduced more than 50% from the baseline or returned to the normal (≤8 times/day) or the average frequency of urgent urination in 24 h was reduced more than 50% from the baseline], the frequency of urination, urgent urination and nocturnal urination before and after treatment, the residual urine volume of the bladder, the quality of life (QOL) score and the occurrence of catheter related adverse events in two groups were compared.Results:114 patients were enrolled in the study, including 76 patients in the test group and 38 patients in the control group. There were no significant differences in the age [(44.2±12.8) vs. (41.7 ± 12.1) years old], male female ratio (13/63 vs. 4/34), average course of disease [2.0(1.2, 5.0) vs. 2.0 (1.0, 4.0) years], the frequency of urination[12.8 (10.6, 16.8) vs. 12.8 (10.3, 17.0) times], urgency urination [11.8(9.3, 15.8) vs. 11.8 (9.0, 17.0) times], nocturia [2.7 (1.3, 3.7) vs. 2.3(0.7, 3.3) times], residual urine volume of bladder [12.0 (3.0, 28.0) vs. 14.0 (3.7, 20.0) ml ] and the QOL score [5.0(4.0, 5.0) vs. 4.0(4.0, 5.0)]before the treatment between the two groups ( P>0.05). The treatment success rate in the test group was 76.3% (58/76), while 26.3% (10/38) in the control group, with a statistically significant difference ( P<0.01). There were significant differences between the test group and control group in the frequency of urination [9.7 (7.7, 12.0) vs. 12.9 (9.6, 15.7) times], urgent urination [7.3 (5.0, 10.0) vs. 11.7 (7.3, 15.3) times], nocturia [1.3 (0.7, 2.0) vs. 1.7 (1.0, 3.0) times] and the QOL score of the patients[3.0(1.0, 3.0) vs. 4.0(3.0, 4.5)]after the treatment(all P<0.05). The frequency of urination, urgency urination, nocturia, the residual urine volume and the QOL score in the test group were significantly improved ( P<0.05) after the treatment.The frequency of urination, nocturia, residual urine volume and the QOL score in the control group were improved ( P<0.05) after the treatment. 13 (11.4%) patients had catheter related adverse events. In the test group and the control group, there were 7 cases of macroscopic hemorrhage caused by the placement of instruments (5/76 vs. 2/38), 5 cases of acute urinary tract infection within 3 days (3/76 vs. 2/38), and 1 case of instrument breakage (catheter breakage) (0/76 vs. 1/38). There were no significant differences in the adverse events between the two groups ( P> 0.05). Conclusions:Radiofrequency treatment of OAB can effectively improve the symptoms of patients, improve the QOL of patients, and has low incidence of adverse events, with good efficacy and safety.

Objective:To explore the construction and application methods of multicenter bone tumor-specific database.Methods:Experts from multiple centers including Shanghai General Hospital, Shanghai Changzheng Hospital, Zhongshan Hospital, Shanghai Sixth People's Hospital, Ruijin Hospital, Fudan University Shanghai Cancer Center and Shanghai Ninth People's Hospital established a standard dataset for bone tumors through research and discussion. Clinical data will be automatically collected and standardized according to standard fields. A database will be built and a users' interface will be developed to ensure secure data storage, while providing services such as exporting raw data, visualizing statistical analysis, establishing clinical queue research projects, et al. Finally, the bone tumor database will be shared by integrating with the Shenkang's Big Data Platform to achieve multi-center data integration.Results:A standard data set for bone tumors containing 603 fields has been established and published. An automated data collection system for bone tumors has been established, including complete data collection, data collation and visualization functions. The data categories include modules such as patients' electronic case information, laboratory information on blood routine, biochemistry and tumor markers, imaging information, surgery information, pathology information and radiotherapy records. Personal information such as patients' names and ID numbers are desensitized and encrypted and can be exported for further research. From 2015 to 2023, the total number of bone tumor cases collected in the database was 10,789. From 2015 to 2019, 112 cases of the osteosarcoma cohort were retrospectively analyzed for admission, with a statistical 5-year survival rate of 68%.Conclusion:A regional bone tumor specialty big data network and data sharing platform has been established, along with data sharing mechanisms and standards including data standards, security standards, and quality evaluation standards. This provides data and efficient new solutions for the construction of China's bone tumor database, as well as a research and development platform for standardized diagnosis and treatment of bone tumors and new technologies.

A multicenter clinical study of robot-assisted total knee arthroplasty / 中华骨科杂志

Objective:To evaluate the accuracy of the domestic "Skywalker" surgical robot in implementing personalized lower limb alignment reconstruction scheme in total knee arthroplasty (TKA) and the short-term clinical outcome of robotic assisted TKA.Methods:From September 2020 to January 2021, the data of patients who received surgical robot assisted TKA in 5 clinical centers in China (Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Southwest Hospital affiliated to Third Military Medical University, The Affiliated Hospital of Qingdao University, The First Affiliated Hospital of Chongqing Medical University and Yantai Yuhuangding Hospital, and Shanghai Ninth People's Hospital affiliated to Shanghai Jiao Tong University School of Medicine was the group leader) were prospectively collected and retrospectively analyzed. There were 24 males and 82 females with an average age of 67.6±7.3 years, (range 45-80 years); Average body mass index 26.42±4.31 kg/m 2, all the operation were performed by "Skywalker" surgical robot system according to preoperative design based on CT. The operation time, intraoperative blood loss, hospitalization days and postoperative complications were recorded, and the imaging indexes including hip-knee-ankle (HKA), lateral distal angle of femur (LDFA) and medial proximal angle of tibia (MPTA) measured before and after the operation, implant model indexes (preoperative planning implant model and postoperative implant model) and short-term clinical efficacy indexes [Western Ontario and McMaster Universities (WOMAC) osteoarthritis index] pain score, stiffness score, joint function score, total score and SF-12 score before and 3 months after the operation) were compared. Results:The average follow-up period was 109.60±9.80 d, (range 95-143 d). The average operation time of 106 patients was 105.30±23.22 min; The average intraoperative blood loss was 141.70±58.33 ml; The average length of hospitalization was 5.82±2.80 d. One patient had ischemic stroke after operation, and one patient had abnormal liver function after operation. According to the judgment of the investigator, all of them were not related to the operation. The actual angle error is the difference between the preoperative planning angle and the postoperative measurement angle. The absolute error of 99.1% (105/106) of the HKA angle was within 3°, 90.8% (69/76) of LDFA, 98.7% (75/76) of the MPTA. In 45 patients in one center where data were available, the actual implant models used in all patients were consistent with the preoperative planning size, and there were only differences in version selection such as Asian condyle. WOMAC pain score, joint function score, total score was improved from 7.34±2.85, 25.10±9.85, 34.75±13.02 to 3.34±2.66, 14.68±9.64, 18.66±13.49 before and after operation, respectively, which were statistically significant ( P<0.001) and SF-12 physiological score and psychological score were improved form 27.24±6.42, 30.68±8.26 to 38.83±5.74, 39.36±7.85 before and after operation, respectively, which were statistically significant ( t=7.33, P<0.001; t=4.53, P=0.043). Conclusion:Domestic surgical robot system "Skywalker" can assist the surgeon to achieve accurate and personalized reconstruction of lower limb alignment and achieve satisfactory short-term clinical outcomes. The long-term clinical outcomes of personalized reconstruction and survival rate of implant still need to be further studied.

3D-printing-assisted surgery versus conventional surgery for treatment of Schatzker VI tibial plateau fractures: a multi-center clinical study / 中华创伤骨科杂志

Objective:To compare 3D-printing-assisted surgery and conventional surgery in the treatment of Schazker type Ⅵ tibial plateau fractures.Methods:A retrospective study was conducted to analyze the clinical data of 50 patients with type Ⅵ tibial plateau fracture who had been treated from January 2019 to December 2021 at the 5 Departments of Orthopedics in The First Affiliated Hospital of Nanchang University, The First People's Hospital of Jiujiang, Pingkuang General Hospital, Ganzhou People's Hospital, and Nanchang Hongdu Hospital of Traditional Chinese Medicine. The patients were divided into 2 groups according to their different treatment methods. In the 3D printing group of 25 cases treated by 3D-printing-assisted surgery, there were 14 males and 11 females, with an age of (42.5±9.1) years; in the conventional group of 25 cases treated by conventional surgery, there were 13 males and 12 females with an age of (42.2±9.3) years. The 2 groups were compared in terms of operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, fracture healing time, postoperative complications, the Rasmussen radiological scores and the American Hospital for Special Surgery (HSS) knee function scores at 6 and 12 months after operation.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The operation time [(125.4±10.6) min], intraoperative blood loss [(206.2±16.3) mL], intraoperative fluoroscopy frequency [(9.2±2.7) times] and fracture healing time [(3.0±0.7) months] in the 3D printing group were all significantly less than those in the conventional group [(168.2±14.1) min, (303.2±20.4) mL, (15.5±3.5) times and (4.1±0.8) months] while the Rasmussen radiological scores (17.6±1.2 and 17.9±0.6) and HSS knee scores (90.8±6.4 and 91.5±5.6) at 6 and 12 months after operation in the 3D printing group were all significantly higher than those in the conventional group (16.2±2.6 and 16.7±2.2; 84.5±9.2 and 87.6±8.0) (all P<0.05). In the 3D printing group, there were 1 case of wound infection and 1 case of wound dehiscence after operation. In the conventional group, there were 2 cases of wound skin necrosis, 3 cases of wound dehiscence, 1 case of traumatic arthritis, 2 cases of wound infection, and 1 case of screw loosening. The incidence of complications in the 3D printing group (8.0%, 2/28) was significantly lower than that in the conventional group (36.0%, 9/25) ( P<0.05). Conclusion:In the treatment of Schatzker type VI tibial plateau fractures, compared with conventional surgery, 3D-printing-assisted surgery can lead to better curative outcomes, because it is conducive to lowering surgical difficulty, reducing postoperative complications, and promoting fracture union and functional recovery of the knee.

Factores asociados a la satisfacción estudiantil con docentes, infraestructura e investigación en escuelas médicas latinoamericanas

Introducción: La satisfacción estudiantil con los programas académicos es importante en la educación médica, para crear futuros galenos competentes. No hay estudios latinoamericanos multicéntricos que determinen sus factores asociados, pare mejorar el currículo médico. Objetivo: Determinar el porcentaje y factores asociados a la satisfacción estudiantil con docentes, infraestructura e investigación en 9 escuelas médicas latinoamericanas. Métodos: Estudio transversal descriptivo de datos secundarios obtenidos mediante cuestionario administrado a estudiantes de medicina de 9 universidades latinoamericanas; indagó variables socioeducativas y la satisfacción estudiantil respecto a docentes, infraestructura e investigación de las universidades. Para el análisis se usaron modelos lineales generalizados. Resultados: De 2 649 encuestados, 57 % eran mujeres con mediana de 22 años. Menos del 50 % estuvo satisfecho con infraestructura e investigación; solo frente a docencia hubo 66 % de satisfacción; Colombia fue el de mayor satisfacción con los docentes, con 82 % de encuestados satisfechos, mientras que Chile fue el país más satisfecho respecto a la infraestructura e investigación universitaria, con 67 % y 68 %, respectivamente. Estudiar en universidad privada se asoció a satisfacción con docentes (p= 0,002), infraestructura (p= 0,001) e investigación (p= 0,018), esta última mayor en mujeres (p= 0,033), pero menor en quienes sentían que les alcanzaba el dinero del mes (p= 0,001). Conclusiones: La satisfacción médico-estudiantil en universidades latinoamericanas tiende hacia la baja, están más satisfechos los de universidades privadas, tienen mayor satisfacción frente a la investigación las mujeres y menor quienes sienten que les alcanza el dinero hasta fin de mes.

Introduction: Student satisfaction with academic programs is important in medical education to create future competent doctors. There are not multicenter Latin American studies that determine its factors related, to improve medical curricula. Objective: To determine the percentage and factors associated with student satisfaction with teachers, infrastructure, and research in 9 Latin American medical schools. Methods: Descriptive cross-sectional study of secondary data obtained through an administered questionnaire to medical students from 9 Latin American universities between 2016-2017, which inquired about socio-educational variables and student satisfaction regarding teachers, infrastructure, and university research. Generalized Linear Models-GLM was used for the analysis. Results: Of 2 649 surveyed, 57% were women, the median was 22 years. Less than 50% were satisfied with infrastructure and research, only compared to teaching there was 66% satisfaction, Colombia ranking as the one with the highest satisfaction with teachers, with 82% of satisfied respondents, while Chile was the most satisfied country regarding infrastructure and university research with 67% and 68%, respectively. Studying at a private university was associated with teacher satisfaction (p= 0.002), infrastructure (p= 0.001) and research (p= 0.018), the latter was higher in women (p= 0.033), but lower in those who felt that the money of the month was reaching them (p= 0.001). Conclusions: Medical-student satisfaction with Latin American universities is tending downward, with those studying at private universities being more satisfied, women having greater satisfaction with research and less for those who feel that they have enough money until the end of the month.

Características laborales y académicas de los recursos humanos del sistema de salud en ocho países de Latinoamérica / Labor characteristics and postgraduate studies of human resources in health in eight Latin American countries

RESUMEN Introducción: la mayoría de las investigaciones muestran la situación de los recursos humanos del sistema de salud en países primermundistas, por lo que es necesario caracterizar nuestra realidad latinoamericana en este aspecto. Objetivo: caracterizar el tipo de trabajo y la formación de posgrado de los recursos humanos del área de salud en ocho países de Latinoamérica. Métodos: se realizó un estudio descriptivo a través de encuestas autoaplicadas sobre las características de los centros de labores y capacitaciones de posgrado que se han tenido. Resultados: de las 1.283 personas que respondieron la encuesta, el 87,1 % laboraba en un hospital (salario promedio mensual: 840 dólares), el 23,3 % también lo hacía en una clínica (salario promedio mensual: 1.200 dólares). Además, solo el 20,5 % trabajaba en un establecimiento del primer nivel de atención (salario promedio mensual: 420 dólares). El 31,2 % había realizado un curso de posgrado, el 23,2 % un diplomado, el 17,8 % una maestría y, el 5,1 %, un doctorado. Conclusiones: los recursos humanos en salud trabajan principalmente en hospitales con sueldos diferentes según el lugar donde laboran. Los médicos son los que tienen mayor remuneración, pero en el sector privado las diferencias son menos marcadas. Menos de la tercera parte han hecho cursos u otras actividades académicas culminadas hace ya varios años. Esto sirve para la mejora de las características laborales y de capacitación.

SUMMARY Introduction: Most research shows the situation of first world countries regarding human resources of health; therefore, it is necessary to characterize our Latin American reality. Objective: To characterize the type of work and postgraduate training of health human resources in eight Latin American countries. Methods: A descriptive study was carried out, through self-applied surveys on the characteristics of its work center, and post-graduate training that them has had. Results: Of the 1283 people who responded to the survey, 87.1% worked in a hospital (average monthly salary: 840 dollars), 23.3% also worked in a clinic (average monthly salary: 1200 dollars). In addition, only 20.5% worked in an establishment of the first level of care (average monthly salary: 420 dollars). 31.2% had completed a post-graduate course, 23.2% had a diploma, 17.8% had a master's degree and 5.1% had a doctoral degree. Conclusions: The human resources in health work mainly in hospitals and the salaries are different according to the place where they work. The physicians are those who have higher remuneration, but in the private sector the salaries are more similar than in the other sectors. Less than a third have taken courses or other academic activities, having been completed several years ago. This serves to improve the work and training characteristics.

A multicenter, double-blind, randomized controlled clinical trial comparing ergometrine with oxytocin and oxytocin alone for prevention of postpartum hemorrhage at cesarean section / 中华妇产科杂志

Objective:To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS).Methods:This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration.Results:(1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant ( P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups ( P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant ( P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion:The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

Epidemiological characteristics of geriatric hip fracture in Beijing: a multicenter analysis of 2,071 cases / 中华创伤骨科杂志

Objective:To explore the epidemiological characteristics of geriatric hip fractures in Beijing so as to provide evidence for effective prevention and control measures.Methods:This multicenter study was conducted in 3 urban (Beijing Jishuitan Hospital, Beijing Hospital and Beijing Anzhen Hospital) and 3 suburban hospitals (Beijing Shunyi District Hospital, Beijing Changping District Hospital and Beijing Liangxiang Hospital) in Beijing from November 2018 to November 2019. Eligible patients were those aged ≥ 65 years with hip fracture confirmed by X-ray and being admitted to hospital within 21 days of injury. To explore the epidemiological characteristics of geriatric hip fractures in Beijing, such data were collected as patients' age, gender, comorbidities, as well as type, site, time and cause of the fracture.Results:① A total of 2,071 patients were included in this suevey. They were 653 males and 1,418 females (M∶F=1∶2.17). Their age ranged from 65 to 102 years (average, 79.8 years). The patients aged from 75 to 84 years were the most common, accounting for 44.81% (928/2,071). ② Femoral neck fractures accounted for 43.41% (899/2,071), and intertrochanteric fractures accounted for 56.59% (1,172/2,071). The age of the patients with femoral neck fracture was (78.6±7.7) years, which was significantly younger than that of those with intertrochanteric fracture [(80.7±7.4) years] ( P<0.05). ③ 94.69% of the hip fractures (1,961/2,071) were caused by falling, and 71.27% fractures (1,476/2,071) happened at home. ④ Approximately 83.00% of the patients (1,719/2,071) had one or more comorbid conditions. Hypertension was the most prevalent disease (57.89%, 1,199/2,071), followed by diabetes (27.09%, 561/2,071), and coronary atherosclerotic heart disease (22.02%, 456/2,071). Conclusions:In Beijing, significantly more geriatric females sustain a hip fracture than males, and the proportion of those aged from 75 to 84 year is the largest. The proportion of intertrochanteric fractures increases with age. Falls are the leading cause for geriatric hip fractures. Most of the patients have one or more chronic comorbid conditions. Corresponding prevention and intervention measures should be formulated according to the distribution characteristics of elderly hip fractures in Beijing.

Multicenter study on the effect of early screening skills training for autism spectrum disorders in primary care hospitals in Chengdu / 四川精神卫生

ObjectiveTo investigate effect of conducting training of autism spectrum disorder （ASD） early screening skill on improving the ability to early identify ASD of medical staffs in primary care hospitals. MethodsIn September 2021， the training of ASD early screening skills was carried out for medical staffs from 20 primary care hospitals in Chengdu. After training， the training effect was evaluated. The numbers of referrals from primary care hospitals to superior hospitals， confirmed ASD as well as their average diagnostic age of children with ASD before and after training were used as evaluation indicators. ResultsAfter training， the number of children with suspected ASD referred by primary care hospitals was more than that before training ［（16.65±11.60） vs. （3.40±2.23）， t=5.431， P<0.01］， the number of children diagnosed with ASD was more than that before training［（6.85±4.93） vs. （2.45±1.67）， t=4.171， P<0.01］， and the differences were statistically significant. As for the diagnosed age of ASD children， after training， the average age was lower than that before training ［（34.95±11.67） vs. （42.2±14.64）， t=-2.553， P=0.019］. ConclusionTraining of ASD early screening skills for medical staffs in primary care hospitals may help to improve their ability to early screening ASD children.

Repercussões da infodemia associada ao COVID-19 na saúde mental do idoso no Brasil / Repercusiones de la infodemia asociada al COVID-19 en la salud mental de los ancianos en Brasil / Repercussions of infodemia associated with COVID-19 on the mental health of the elderly in Brazil

O fenômeno denominado infodemia refere-se ao aumento do volume informacional sobre um tema em específico, que se multiplica rapidamente em um curto período de tempo, e tem-se destacado frente ao contexto da crise sanitária desencadeada pela pandemia de COVID-19. O excesso de informações pode suscitar sentimentos de medo, ansiedade, estresse e outras condições de sofrimento mental. O estudo tem como objetivo descrever o perfil de exposição a informações sobre COVID-19 e suas repercussões na saúde mental de idosos brasileiros. Trata-se de um estudo transversal realizado com 1924 idosos brasileiros. Coletaram-se dados por meio de web-based survey enviada aos idosos por redes sociais e e-mail, no período de julho a outubro de 2020. Os resultados da análise descritiva dos dados demonstram que a maioria dos idosos apresentou idade entre 60 e 69 anos (69,02por cento), é do sexo feminino (71,26por cento), casados (53,79 por cento) e de cor branca (75,57por cento). Cerca de 21,67por cento (n = 417) concluíram a graduação, 19,75por cento (380) concluíram especialização e 16,63por cento (320) concluíram mestrado ou doutorado. Foram reportados como fontes frequentes de exposição às notícias ou informações sobre a COVID-19, a televisão 862 (44,80por cento) e as redes sociais 651 (33,84por cento). Os participantes assinalaram que a televisão (46,47por cento; n = 872), as redes sociais (30,81por cento; n = 575) e o rádio (14,48por cento; 251) os afetavam psicológica e/ou fisicamente. Receber notícias falsas sobre a COVID-19 pela televisão (n = 482; 19,8por cento) e pelas redes sociais (n = 415; 21,5por cento) repercutiu, principalmente, estresse e medo. As informações disseminadas contribuem para conscientização, mas, também, afetam física e/ou psicologicamente muitos idosos, principalmente gerando medo e estresse(AU)

El fenómeno denominado infodemia hace referencia al aumento del volumen de información sobre un tema específico, que se multiplica rápidamente en un corto período, y ha destacado en el contexto de la crisis sanitaria desencadenada por la pandemia de la COVID-19. Demasiada información puede desencadenar sentimientos de miedo, ansiedad, estrés y otras condiciones de angustia mental. El estudio tiene como objetivo describir el perfil de exposición a la información sobre la COVID-19 y sus repercusiones en la salud mental de los ancianos brasileños. Se trata de un estudio transversal realizado con 1924 ancianos brasileños. Los datos fueron recolectados a través de una encuesta web enviada a los ancianos a través de redes sociales y correo electrónico, de julio a octubre de 2020. Los resultados del análisis descriptivo de los datos muestran que la mayoría de los ancianos tenían entre 60 y 69 años (69,02 por ciento), mujer (71,26 por ciento), casada (53,79 por ciento) y blanca (75,57 por ciento). El 21,67 por ciento (n = 417) concluyó su graduación, el 19,75 por ciento (380) concluyó especialización y el 16,63 por ciento (320) concluyó maestría o doctorado. La televisión 862 (44,80 por ciento) y las redes sociales 651 (33,84 por ciento) se reportaron como fuentes frecuentes de exposición a noticias o información sobre el COVID-19. Los participantes indicaron que la televisión (46,47 por ciento; n = 872), las redes sociales (30,81 por ciento; n = 575) y la radio (14,48 por ciento; 251) les afectaban psicológica y/o físicamente. Recibir noticias falsas sobre el COVID-19 en la televisión (n = 482; 19,8 por ciento) y en las redes sociales (n = 415; 21,5 por ciento) resultó principalmente en estrés y miedo. La información difundida contribuye a la sensibilización, pero también afecta física y/o psicológicamente a muchas personas mayores, generando principalmente miedo y estrés(AU)

The phenomenon called infodemia refers to the increase in the volume of information on a specific topic, which multiplies rapidly in a short period of time, and has stood out in the context of the health crisis triggered by the COVID-19 pandemic. Too much information can trigger feelings of fear, anxiety, stress, and other conditions of mental distress. The study aims to describe the profile of exposure to information about COVID-19 and its repercussions on the mental health of elderly Brazilians. This is a cross-sectional study carried out with 1924 elderly Brazilians. Data were collected through a web-based survey sent to the elderly via social networks and email, from July to October 2020. The results of the descriptive analysis of the data show that most of the elderly were aged between 60 and 69 years (69.02percent), female (71.26percent), married (53.79percent) and white (75.57percent). About 21.67percent (n = 417) concluded their graduation, 19.75percent (380) concluded their specialization and 16.63percent (320) concluded their master's or doctoral degrees. Television 862 (44.80percent) and social networks 651 (33.84percent) were reported as frequent sources of exposure to news or information about COVID-19. Participants indicated that television (46.47percent; n = 872), social networks (30.81percent; n = 575) and radio (14.48percent; 251) affected them psychologically and/or physically. Receiving fake news about COVID-19 on television (n = 482; 19.8percent) and on social media (n = 415; 21.5percent) mainly resulted in stress and fear. The disseminated information contributes to awareness, but also affects physically and/or psychologically many elderly people, mainly generating fear and stress(AU)

The normal values of water-perfused high resolution esophageal manometry: a multicenter study / 中华消化杂志

Objective:To establish the normal values of water-perfused high resolution esophageal manometry (HREM)(GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing in Chinese population.Methods:From September 1, 2019 to June 30, 2020, 91 healthy volunteers receiving water-perfused HREM (GAP-36A) at resting period, water swallowing, semisolid swallowing and solid swallowing were selected from 9 hospitals (Union Hospital, Tongji Medical College, Huazhong University of Science and Technology; the First Affiliated Hospital of Dalian Medical University; the Second Hospital of Hebei Medical University; the Second Affiliated Hospital, Naval Medical University; the First Affiliated Hospital, Sun Yat-sen University; the First Affiliated Hospital, University of Science and Technology of China; Aviation General Hospital of China Medical University; the Affiliated Hospital of Medical School of Nanjing University and the First People′s Hospital of Yichang). Parameters included the position of the upper and lower edges of the upper esophageal sphincter (UES) and lower esophageal sphincter (LES), the length of the LES and UES, the position of the pressure inversion point (PIP), the resting pressure of UES and LES and swallow-related parameters such as the distal contraction integral (DCI), 4 s integrated relaxation pressure (IRP), distal latency (DL) and UES residual pressure. One-way analysis of variance, post-hoc test and sum rank test were used for statistical analysis.Results:A total of 87 healthy volunteers were enrolled, including 40 males and 47 females, aged (38.5±14.2) years old (ranged from 19 to 65 years old). The position of the upper and lower edges of the LES was (42.7±2.8) and (45.6±2.8) cm, respectively, the length of the LES was (2.9±0.4) cm, and the position of PIP was (43.3±2.8) cm. The position of the upper and lower edges of the UES was (18.1±3.0) and (22.6±2.0) cm, respectively, and the length of the UES was (4.8±1.0) cm. The resting pressure of LES and UES was (17.4±10.7) and (84.1±61.1) mmHg (1 mmHg=0.133 kPa), respectively. The DCI value at solid swallowing was higher than those at water swallowing and semisolid swallowing ((2 512.4±1 448.0) mmHg·s·cm vs. (2 183.2±1 441.2) and (2 150.8±1 244.8) mmHg·s·cm), and the differences were statistically significant ( t=-4.30 and -3.74, both P<0.001). The values of 4 s IRP at semisolid swallowing and solid swallowing were lower than that at water swallowing ((4.6±4.1) and (4.9±3.9) mmHg vs. (5.4±3.9) mmHg), and the differences were statistically significant ( t=3.38 and 2.09, P=0.001 and 0.037). The DL at water swallowing was shorter than those at semisolid swallowing and solid swallowing ((8.5±1.8) s vs. (9.8±2.2) and (10.6±2.8) s), and the DL at semisolid swallowing was shorter than that at solid swallowing, and the differences were statistically significant ( t=-10.21, -13.91 and -4.68, all P<0.001). The UES residual pressure at water swallowing was higher than those at semisolid swallowing and solid swallowing (9.5 mmHg, 6.5 to 12.3 mmHg vs. 8.0 mmHg, 4.5 to 11.7 mmHg and 5.5 mmHg, 2.0 to 9.3 mmHg), and the UES residual pressure at semisolid swallowing was higher than that at solid swallowing, and the differences were statistically significant ( t=3.48, 10.30 and 6.35, all P<0.001). Conclusions:The normal values of water-perfused HREM (GAP-36A) in Chinese population at resting period, water swallowing, semisolid swallowing and solid swallowing can provide a reference basis for clinical diagnosis and treatment for patients receiving water-perfused HREM examination.
