SUMMARY The COVID-19 pandemic forced the school of medicines to opt for a virtual teaching modality due to the suspension of face-to-face activities imposed by the lockdown. Objective To determine the advantages and disadvantages of the virtual teaching modality perceived by the students in an introduction to clinical medicine course of a school of medicine in Lima, Peru. Methods A virtual non-validated survey was circulated among fourth year medical students. Results 94 studentes answered the survey (51%). Perceived advantages were to have more time to study (57.4%) and saving time in transportation (39.4%). The disadvantages were lack of contact with real patients (42.6%) and not to be able to obtain a clinical history from patients (39.4%). The 72.3% of students were able to identify the medical problems of patients, but only 24.4% were able to obtain an adequate clinical history and just 9.6% performed an adequate physical examination. Conclusion The virtual teaching modality allowed the student to have more time for self-study but limited their abilities to obtain a clinical history and to perform a physical examination.

Estrangulación/sofocación no fatal en el contexto de violencia de género: Aspectos médico-legales e implicancias para la práctica clínica / Non-fatal strangulation/suffocation in context of gender violence: Medicolegal aspects and implications in clinical practice

RESUMEN A pesar de los numerosos esfuerzos de la comunidad internacional en pos de erradicar todas las formas de violencia contra las mujeres, esta problemática se encuentra lejos de ser resuelta. Según la ONU, una de cada tres mujeres ha sufrido violencia física o sexual por parte de la pareja, violencia sexual fuera de la pareja, o de ambas, al menos una vez en su vida. El abordaje de esta problemática, en tanto necesidad social de salud de grupos poblacionales, permite una aproximación a la violencia de género como un problema de salud colectiva. En el plano de la violencia física, la estrangulación/sofocación ha sido identificada como una de las formas más letales de violencia doméstica y agresión sexual; se ha reportado que una víctima que es estrangulada una primera vez tiene 7,5 más probabilidades de ser asesinada posteriormente por el mismo abusador. Una víctima de estrangulación/sofocación puede perder la conciencia en segundos o morir en minutos, días o semanas después del ataque o sufrir daño cerebral permanente o invalidez, además del trauma emocional. Recientemente, se han generado cambios legales en la configuración de este delito; las penas han aumentado en el Reino Unido, Estados Unidos, Australia y Nueva Zelandia. El propósito de esta revisión de literatura de tipo narrativo, no sistemática, está orientada a presentar aspectos médico-legales actualizados de la estrangulación/sofocación no fatal en el contexto de la violencia de género, y se resaltan aquellas implicancias relevantes para la práctica clínica.

ABSTRACT Despite the numerous efforts of the international community to eradicate all forms of violence against women, this problem is far from being resolved. According to the UN, one in three women has suffered physical or sexual violence from an intimate partner, sexual violence outside the couple, or both at least once in their life. Addressing this problem as a social health need of population groups allows an approach to gender violence as a collective health problem. At the level of physical violence, strangulation/suffocation has been identified as one of the most lethal forms of domestic violence and sexual assault. Victims of domestic violence who have been choked or strangled are 7.5 times more likely to be killed by their partner. A victim of strangulation/suffocation can lose consciousness in seconds or die within minutes, days or weeks after the attack, as well as suffer permanent brain damage or disability or emotional trauma. Recently, legal changes have been generated in the configuration of this crime, the penalties have increased in United Kingdom, the United States, Australia and New Zealand. The current non-systematic narrative review of literature sought to explore updated medico-legal aspects of non-fatal strangulation/suffocation in the context of gender violence, and are highlightedrelevant implications for clinical practice.

Correlation between grip strength promotion and improvement of body composition and metabolic disorders in health examination population of different genders / 中华健康管理学杂志

Objective:To explore the correlation between grip strength promotion and improvement of body composition and metabolic disorders in health examination population of different genders.Methods:In this retrospective cohort study, clinical data of 600 people who received health examination and grip strength check-up two times or more in the Medical Examination Center of Peking University Third Hospital from January 2018 to November 2022 were selected. The general data, physical examination, biochemical parameters, body composition and grip strength results were collected. After the first physical examination, the grip strength test was conducted, appropriate resistance strength exercises were given based on individual evaluation results. A health lecture was held, and the information related to health exercise was pushed through WeChat official account every week. The grip strength test was completed at the same time at the second physical examination, and the difference between the two test results was calculated before and after the second physical examination. The generalized estimation equation was used to analyze the correlation between the improvement of grip strength and the improvement of body composition and metabolic disorders in different gender health-check population.Results:In man and women, the body mass index [(25.50±3.66) vs (25.33±3.74) kg/m 2, (22.41±3.55) vs (22.25±3.46) kg/m 2] and grip strength [(42.71±7.30) vs (41.77±7.36) kg, (25.28±5.30) vs (23.98±4.87) kg] at the second health check-up were all significantly higher than those at the first time, and the diastolic blood pressure [(72.79±10.30) vs (74.47±9.85) mmHg (1 mmHg=0.133 kPa), (66.93±8.90) vs (68.92±9.42) mmHg] and serum homocysteine [(17.96±14.09) vs (19.27±14.26) μmol/L, (9.47±3.91) vs (10.26±3.90) μmol/L] were all significantly lower than those at the first time (all P<0.05). Among man, the low-density lipoprotein cholesterol (LDL-C) at the second physical examination was significantly lower than that at the first time [(2.94±0.78) vs (3.00±0.69) mmol/L] (all P<0.05). Among women, the systolic blood pressure and uric acid at the second health check-up were both significantly lower than those at the first time [(109.34±12.85) vs (110.54±12.32) mmHg, (276.91±62.46) vs (287.16±68.78) μmol/L], and the waist-hip ratio was significant higher (85.8%±5.1% vs 85.4%±5.0%) (all P<0.05). In males, the decreased aspartate aminotransferase ( OR=0.932, 95% CI: 0.888-0.978) and the increased skeletal muscle index ( OR=75.370, 95% CI: 29.012-195.806) were both positively correlated with the elevation of grip strength (all P<0.05); and in females, the decreased homocysteine ( OR=0.876, 95% CI: 0.782-0.982) and glycosylated hemoglobin ( OR=0.423, 95% CI: 0.222-0.805) and increased skeletal muscle index ( OR=22.918, 95% CI: 11.114-47.256) were all positively correlated with the elevation of grip strength (all P<0.05). Conclusion:There is a positive correlation between the improvement of grip strength and the improvement trend of body composition and metabolic disorders in in health examination population of different genders.

Multiple correspondence analysis of the detection and risk factors of non-alcoholic fatty liver disease in middle-aged and young adult population undergoing physical examination / 中华健康管理学杂志

Objective:To analyze the detection of non-alcoholic fatty liver disease (NAFLD) and the multiple corresponding relationships of its risk factors in a middle-aged and young adult population undergoing health check-ups.Methods:This study was a cross-sectional study conducted on 15 423 individuals aged between 18 and 59 who underwent health check-ups at the Health Management Center of Henan Provincial Hospital of Traditional Chinese Medicine from January to December 2021. Relevant health examination data was collected, including basic information (age, gender, past medical history, smoking and alcohol consumption), physical examination, laboratory indicators such as blood lipids and blood glucose, and abdominal ultrasound results. The chi-square test was used to compare the prevalence of NAFLD among different characteristics of the population, and multiple correspondence analysis was employed for statistical analysis of related influencing factors.Results:A total of 5 859 cases of NAFLD were detected in this study, with a detection rate of 37.99%. The detection rate of NAFLD gradually increased with age ( χ2=828.841, P<0.001) and body mass index (BMI) ( χ2=1 889.809, P<0.001). The detection rates of NAFLD were higher in individuals with hypertension, diabetes, hypercholesterolemia, hypertriglyceridemia, low high-density lipoprotein cholesterolemia, high low-density lipoprotein cholesterolemia, and hyperuricemia compared to those without these conditions ( χ2 value was 1 223.673, 364.808, 444.074, 2 436.765, 1 323.736, 591.478, and 943.069, respectively, all P<0.001). Multiple correspondence analysis revealed that NAFLD was closely related to hypertension, hypertriglyceridemia, diabetes, hyperuricemia, overweight, obesity, and the age group of 45-49 years. Correspondence analysis graphs for males and females showed associations between NAFLD and hypertension, hypertriglyceridemia, hyperuricemia, overweight, and obesity. In males, NAFLD was closely related to the age group of 35-49 years, while in females, it was closely associated with the age group of 45-49 years and diabetes. Conclusions:The detection rate of non-alcoholic fatty liver disease is relatively high in middle-aged and young adult populations. Males, those who are overweight or obese, and individuals with hypertension, diabetes, hyperuricemia, or abnormal blood lipids are more susceptible to non-alcoholic fatty liver disease.

Objective:To evaluate the application value of serum carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 19-9 and CA72-4 detection in the opportunistic screening (healthy physical examination) of gastric cancer based on a meta-analysis.Methods:A published literature searching up to May 2023 was performed in databases of CNKI, Wanfang Databases, VIP, PubMed, Cochran and Embase for studies on CEA, CA19-9 and CA72-4 detection and diagnosis of gastric cancer. The Quality Evaluation Tool of Diagnostic Accuracy Studies (QUADAS-2) was used to evaluate the quality of the literature. Stata17.0 statistical software was used for meta-analysis.Results:According to the inclusion and exclusion criteria, a total of 23 studies with 5 287 gastric cancer patients and 6 129 controls were included. The pooled sensitivity and specificity of serum CEA, CA19-9 and CA72-4 as a diagnostic marker for gastric cancer were 0.42, 0.45 and 0.52, and 0.94, 0.91 and 0.95, respectively. The area under the summary receiver operating characteristic (sROC) curve for discriminating gastric cancer was 0.82, 0.77 and 0.87, respectively. The sensitivity of combined (parallel) diagnosis of gastric cancer with the three biomarkers increased to 0.66 (95% CI: 0.54-0.76), the specificity decreased to 0.85 (95% CI: 0.81-0.89), and the area under the curve basically remained unchanged at 0.86 (95% CI: 0.83-0.89). Conclusions:Due to poor sensitivity, the application effects of serum CEA, CA19-9 and CA72-4 as biomarkers for gastric cancer screening and physical examination are limited.

Conclusion The Hp infection rate and antibody Ure positive rate are higher in physical examination people in plateau area, and chronic gastric disease history and often eating pickled or barbecued foods are risk factors of Hp infection.

Quality of Life After Diagnosis of Neurally Mediated Reflex Syncope by Tilt Test

Abstract Background: Vasovagal syncope (VVS) results in impaired quality of life (QoL). The response during the head-up tilt test (HUTT) influences QoL and recurrence. Objectives: To analyze the influence of the type of HUTT response on QoL in patients with VVS and recurrence of events after the exam. Methods: The SF-36 and Impact of Syncope on Quality of Life (ISQL) questionnaires were applied over 12 months after the HUTT. Unpaired Student's t test was used for differences between 2 groups of quantitative data with normal distribution. The recurrence of syncope episodes was analyzed using a Kaplan-Meier curve, and the log-rank test was applied to compare the curves regarding responses to the HUTT. Statistical significance was set at p value < 0.05. Results: We analyzed 82 patients (43.7 years old), 69% with previous recurrence (2.8 prior episodes). Cardioinhibitory response occurred in 46 patients; vasodepressor response occurred in 36, and 85.4% of patients received non-pharmacological treatment after the HUTT. During clinical follow-up, 43.9% had recurrence, mainly young patients (35.7 years; p = 0.002). On the SF-36, the best score was in functional capacity in men (p = 0.04) and patients without prior trauma (p = 0.001). There were lower limitations due to pain in patients without prior trauma (p = 0.003) and patients without prodromes (p = 0.009). On the ISQL, there were better mean scores in men (p = 0.002) and in patients without prior trauma (p = 0.02). Patients with cardioinhibitory response had better SF-36 and ISQL scores (p < 0.001). There was greater VVS recurrence in the cardioinhibitory response group (log-rank p = 0.011; hazard ratio: 8.48; 95% confidence interval: 7.59 to 9.3) from the second to the fourth month, with stabilization in the eighth month after the HUTT, when compared to patients with vasodepressor response. Conclusion: The majority of patients with VVS reproduced during the HUTT under non-pharmacological treatment did not report worsening of QoL during clinical follow-up. Worse QoL was observed in non-young patients and in patients with vasodepressor response, and it was not influenced by recurrence after the HUTT.

Shortening of clavicle fractures: physical versus image examinations / Encurtamento de fraturas de clavícula: exame físico versus exame de imagem

ABSTRACT Objective: Determine the reliability of three different methods of evaluating bone shortening in displaced midshaft clavicle fractures (DCMF). Method: A cross-sectional analytical study evaluated bone shortening by metric tape (MT), radiography (X-ray), and computed tomography (CT). Twenty-six men had been evaluated and used clavícula not broken as control. The collection of data was of the blind type for three specialists. Differences and reliability were analyzed with the Friedman and Kappa tests and validated with the T-test (CI: 95%; significance index p<0.05; Software "R" version 3.2.2). Results: The MT measurements (control) showed abnormal distribution and significant statistical difference concerning the imaging tests (p=0.000008). There was a similarity between X-ray and CT and Kappa agreement of 0.65. The fractured clavicles presented similar measurements between the three methods (p=0.059), and the T-tests proved that the similarity was caused by chance or possible measurement errors. Conclusion: Measurement by metric tape showed a tendency to overestimate bone shortening. The CT showed more reliable results for the diagnosis; however, the X-ray was sufficient for decision-making by surgeons, and therefore, it is not possible to rule out the importance of this resource for DCMF. Level of Evidence IV; Case-Control Study.

RESUMO Objetivo: Determinar a confiabilidade de três diferentes métodos de avaliação do encurtamento ósseo em fraturas deslocadas do eixo médio da clavícula (FDEMC). Método: Estudo analítico transversal que avaliou o encurtamento ósseo por fita métrica (FM), radiografia (X-Ray) e tomografia computadorizada (TC). Foram avaliados 26 homens utilizando a clavícula não fraturada como controle. A coleta de dados foi do tipo cega por três especialistas. As diferenças e a confiabilidade foram analisadas com os testes de Friedman e Kappa e validados com o teste T (IC:95%; índice de significância p<0,05; Software "R" versão 3.2.2). Resultados: As medidas de FM (controle), apresentaram distribuição anormal e diferença estatísfica significativa em relação aos exames de imagem (p=0,000008). Houve semelhança entre radiografia e TC, concordância Kappa 0,65. As clavículas fraturadas apresentaram medidas semelhantes entre os três métodos (p=0,059) e os testes-T comprovaram que a semelhança foi provocada casualmente ou possíveis erros de medição. Conclusão: A medição por fita métrica apresentou tendência em superestimação do encurtamento ósseo. A TC apresentou resultados mais confiáveis para o diagnóstico, contudo, a radiografia foi suficiente para tomada de decisão dos cirurgiões e por isso, não é possível descartar a importância deste recurso para FDEMC. Nível de Evidência IV; Estudo Caso Controle.

Exame físico em ginecologia / Physical examination in gynecology

O exame físico na prática ginecológica diuturna é o sustentáculo de uma perspectiva diagnóstica com vistas a uma abordagem individualizada, oportuna e humanizada da paciente. Lança mão de técnica semiótica clássica, inicialmente, após avaliação de sinais vitais, minuciosa inspeção ectoscópica, seguida de exame físico especial. E deverá ser realizado em ambiente adequadíssimo, sem nenhuma improvisação e ou adaptações não compatíveis, com a importância e a segurança garantidas por um exame físico de boa qualidade. O exame físico de mamas tem como objetivo primordial a identificação de nódulos mamários e, eventualmente, de tumores localmente avançados; e relativa tranquilidade é assegurada às pacientes quando ele é considerado normal. O exame físico vulvar permite a identificação de prolapso de órgãos pélvicos, neoplasia intraepitelial e/ou invasiva vulvar e distúrbios de desenvolvimento sexual, além de oferecer subsídios para a propedêutica da vulvodínea, sendo, principalmente, uma oportunidade para o diagnóstico em dermatologia vulvar, mesmo a vulva correspondendo a apenas 1% da pele feminina. O exame especular, um clássico da ginecologia, é indispensável para a triagem do câncer de colo uterino. Por fim, o toque genital, a despeito de sua subjetividade, permite a avaliação dos órgãos genitais internos.

Physical examination in daytime gynecological practice is the mainstay of a diagnostic perspective with a view to an individualized, timely and humanized approach to the patient; resorting to the classical semiotic technique, initially, after assessing vital signs, a thorough ectoscopic inspection, followed by a special physical examination; which should be carried out in a very suitable environment, without any improvisation or adaptations that are not compatible with the importance and safety guaranteed by a good quality physical examination. The primary objective of the physical examination of the breasts is to identify breast nodules and possibly locally advanced tumors; in addition to relative tranquility, assured to patients, when the respective exam is considered normal. Vulvar physical examination allows the identification of pelvic organ prolapse; vulvar intraepithelial and/or invasive neoplasia; sexual development disorders; in addition to offering subsidies for the propaedeutics of vulvodynia; and, above all, it is an opportunity for diagnosis in vulvar dermatology, even though the vulva accounts for only 1% of female skin. Specular examination, a classic in gynecology, is essential for screening for cervical cancer. Finally, the genital touch which, despite its subjectivity, allows the evaluation of the internal genital organs.

Correlation between body fat distribution measured by quantitative CT and blood lipids in overweight and obese individuals undergoing physical examinations / 中华健康管理学杂志

Objective:To analyze the correlation between quantified body fat distribution measured by computed tomography (CT) and blood lipids in overweight and obese individuals undergoing physical examinations.Methods:In this retrospective cohort study, a total of 3 463 physical examination subjects who underwent chest CT combined with quantified CT examination in the Department of Health Management at Henan Provincial People′s Hospital from January to December 2021 were selected using a comprehensive sampling method. The subjects were divided into three groups: normal group (1, 424 cases), overweight group (1, 531 cases), and obese group (508 cases) based on their body mass index: 18.5 to <24.0 kg/m 2, 24.0 to <28.0 kg/m 2, and≥28.0 kg/m 2, respectively. General information, blood lipid parameters, and different body fat distributions measured by quantified CT (subcutaneous fat area, visceral fat area, total abdominal fat area, liver fat content, muscle fat content) were collected in the three groups. One-way analysis of variance was used to compare differences in body fat distribution and blood lipid parameters, and Pearson correlation analysis was performed to evaluate the correlation between body fat distribution and blood lipids. Results:In the obese group, compared to the normal and overweight groups, subcutaneous fat area, visceral fat area, total abdominal fat area, liver fat content, muscle fat content, total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglyceride levels were significantly higher [males: (152.80±49.27) vs (72.94±22.68), (103.79±28.30) cm 2; (287.95±57.55) vs (156.36±49.40), (224.67±53.10) cm 2; (440.75±72.44) vs (229.31±62.01), (328.46±62.77) cm 2; (12.92±8.61)% vs (6.82±3.31)%, (9.39±4.88)%; (9.06±9.34)% vs (4.55±5.06)%, (6.70±6.73)%; (6.52±0.94) vs (4.87±1.03), (6.27±0.96) mmol/L; (3.05±0.76) vs (2.92±0.86), (2.97±0.77) mmol/L; (2.34±1.42) vs (1.53±0.82), (1.99±1.28) mmol/L; females: (213.82±46.87) vs (104.69±30.62), (155.05±34.90) cm 2; (184.88±46.54) vs (90.67±34.09), (138.92±42.06) cm 2; (398.71±71.28) vs (195.37±55.32), (293.97±57.05) cm 2; (11.36±6.34)% vs (5.51±3.02)%, (7.98±4.77)%; (7.44±7.60)% vs (3.70±3.90)%, (5.56±5.94)%; (5.27±0.96) vs (5.04±0.86), (5.11±0.96) mmol/L; (3.26±0.84) vs (2.92±0.79), (3.01±0.74) mmol/L; (1.74±0.69) vs (1.27±0.65), (1.57±0.77) mmol/L], while high-density lipoprotein cholesterol (HDL-C) was significantly lower [males: (1.17±0.19) vs (1.38±0.28), (1.25±0.25) mmol/L; females: (1.36±0.22) vs (1.59±0.32), (1.42±0.27) mmol/L] (all P<0.001). In males, the visceral fat area and total abdominal fat area in the overweight group were positively correlated with triglycerides ( r=0.175, 0.113) and negatively correlated with HDL-C ( r=-0.125, -0.113), while liver fat content was positively correlated with total cholesterol, LDL-C, and triglycerides ( r=0.083, 0.075, 0.206) and negatively correlated with HDL-C ( r=-0.093) (all P<0.05). In the obese group, the liver fat content was positively correlated with triglycerides ( r=0.170) and negatively correlated with HDL-C ( r=-0.166) in males (both P<0.05). In females, the visceral fat area and total abdominal fat area in the overweight group were positively correlated with total cholesterol, LDL-C, and triglycerides (visceral fat area: r=0.129, 0.160, 0.348; total abdominal fat area: r=0.121, 0.130, 0.283) and negatively correlated with HDL-C ( r=-0.264, -0.173), while liver fat content was positively correlated with triglycerides ( r=0.352) and negatively correlated with HDL-C ( r=-0.195) (all P<0.05). In the obese group, the visceral fat area was positively correlated with triglycerides ( r=0.213) and negatively correlated with HDL-C ( r=-0.223) in females (both P<0.05). Conclusion:Blood lipids are correlated with body fat distribution in overweight and obese individuals undergoing physical examinations, and the degree of correlation varies between different genders and body regions, with triglycerides showing the strongest correlation with liver fat content.

Correlation between UCP2 and FTO gene polymorphisms and visceral fat area in a population undergoing health examinations / 中华健康管理学杂志

Objective:To investigate the correlation between uncoupling protein 2 (UCP2) and fat mass and obesity associated (FTO) gene polymorphisms and visceral fat area in a population undergoing health examinations.Methods:In this retrospective cohort study, 120 people who underwent physical examination in the Health Management Department of Xiaogan Hospital Affiliated to Wuhan University of Science and Technology from January 2020 to December 2021 with a visceral fat area ≥100 cm 2 under the abdominal navel section CT images were included in the superstandard group. In addition, 120 people who received health checkup in the meantime with a visceral fat area <100 cm 2 were included in the normal group. Basic information including age, gender, height, weight, body mass index (BMI), and visceral fat area was collected for both groups. Genotyping was performed, and logistic regression analysis was used to determine the association between UCP2 and FTO gene polymorphisms and visceral fat area. Results:The weight, body mass index, total cholesterol, triglyceride and low density lipoprotein cholesterol (LDL-C) in the superstandard group were all significantly higher than those in the normal group [(78.74±5.35) vs (65.83±4.22) kg, (27.89±3.24) vs (23.43±2.91) kg/m 2, (3.21±1.51) vs (2.32±1.47) mmol/L, (5.29±1.34) vs (4.86±1.16) mmol/L, (2.73±0.89) vs (2.51±0.82) mmol/L], the level of high density lipoprotein cholesterol (HDL-C) was significantly lower than that in normal group [(1.02±0.31) vs (1.23±0.43) mmol/L] (all P<0.05); there were no significant differences in age, gender, height, fasting blood glucose and glycated hemoglobin between the two groups (all P>0.05). The expression ratio of AG/GG allele in UCP2-866A/G and TA, AA and A allele in FTO rs9939609 gene locus in superstandard group were all significantly higher than those in normal group (82.50% vs 69.17%, 38.33% vs 19.17%, 7.50% vs 4.17%, 23.75% vs 15.00%) (all P<0.05). The expression of UCP2 gene ( OR=2.303, 95% CI: 1.456-3.642) and FTO gene ( OR=2.782, 95% CI: 1.149-6.733) were positively correlated with increased visceral fat area (both P<0.05). Conclusion:The presence of UCP2-866A/G or FTO rs9939609 gene polymorphisms in individuals undergoing health examinations significantly increases the risk of increased visceral fat area.

Association between working hours and urinary sodium and potassium excretion levels in a population undergoing health examinations, and the potential mediating effect of timely eating behaviors / 中华健康管理学杂志

Objective:To examine the association between working hours and urinary sodium and potassium excretion levels in a population undergoing health examinations and the potential mediating effect of timely eating behaviors.Methods:In this cross-sectional study, 64 400 people who received health checkups from August 2017 to August 2022 at the Third Xiangya Hospital of Central South University were recruited as study subjects. General information on socio-demographic characteristics of the enrolled subjects were collected using the health checkup self-assessment questionnaire in the Expert Consensus on Basic Items for Health Checkups. Urinary excretion levels of sodium and potassium were measured with the Kawasaki method. The association between working hours and urinary sodium and potassium excretion levels was checked by using Pearson′s correlation analysis. The relationships between timely eating behaviors, working hours, and urinary sodium and potassium excretion levels and their ratios were analyzed using logistic regression and linear regression models, while the mediating mechanisms involved was also examined.Results:Among the 64 400 subjects, there were 39 274 males (60.98%) and 25 126 females (39.02%), the mean age was (43.80±11.13) years. There were 16 980 individuals (26.37%) with an average working time exceeding 8 hours per day. Additionally, 4 332 subjects (6.73%) were unable to eat three meals on time. The mean urinary sodium and potassium excretion and their ratios were (4.12±1.86) g/d, (2.06±0.80) g/d, 2.05±0.66, respectively. There was a significant positive correlation between working hours and urinary sodium excretion, urinary potassium excretion, and their ratios ( r=0.034, 0.021, 0.032, respectivley); it showed that timely eating behavior had a significant negative correlation with urinary sodium and potassium excretion ( r=-0.022, -0.019, respectivley) (all P<0.001). There was a partial mediating effect of timely eating behavior in the association between working hours and urinary sodium excretion (effect value of -0.006), and after stratifying the labor intensity, this mediating effect was only found among individuals engaged in light physical labor (both P<0.001). Conclusions:Prolonged working hours leads to increased levels of urinary sodium and urinary potassium excretion, and timely eating behavior facilitates salt/sodium reduction in light-duty workers.

Objective:To analyze the detection rate of hyperuricemia (HUA) and the distribution of serum uric acid (SUA) levels by multiple correlation analysis in middle-aged and elderly population receiving health examination.Methods:In this cross-sectional study, the study object were 25 587 middle-aged and elderly people who receiving health examination in Nanfang Hospital from January to December in 2014. According to the latest diagnostic criteria, the population was divided into HUA and non-HUA groups. Furthermore, the subjects were divided into 4 groups with the level of SUA (Q 1: SUA<313 μmol/L, Q 2:313 μmol/L≤SUA<375 μmol/L, Q 3:375 μmol/L≤SUA<440 μmol/L, Q 4: SUA≥440 μmol/L). According to the data types, two independent sample t test, Mann-Whitney U test, Chi-square test and multiple correspondence analysis were used for statistical analysis. Results:The mean age of the study subjects was (54.78±8.80) years with 16 570 males (64.8%) and 9 017 females (35.2%). The overall detection rate of HUA was 31.5%, and it was higher in men (43.1%) than in women (10.1%). The body mass index(BMI), systolic blood pressure, diastolic blood pressure, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and fasting blood glucose (FBG) in the HUA group were all higher than those in the non-HUA group (all P<0.001); and high-density lipoprotein cholesterol (HDL-C) was lower than that in the non-HUA group( P<0.001). In multiple correspondence analysis, Cronbach′s α coefficients of the first dimension and the second dimension was 0.608 and 0.237, respectively. Further analysis was performed stratified by gender, it indicated that 45-<55 years old male and overweight were closely associated with the Q 3 group, fatty liver and hyperlipidemia were closely associated with Q 4 group; the 55-<65 years old female, hyperlipidemia, fatty liver and obesity were closely associated with the Q 3 group, while hyperglycemia and hypertension were closely associated with the Q 4 group. Conclusion:The detection rate of HUA in middle-aged and elderly population receiving health examination was high, and the detection rate of HUA in male was higher than that in female. SUA levels are higher in middle-aged and elderly men who have fatty liver and hyperlipidemia. While SUA levels are higher in middle-aged and elderly women who have hyperglycemia and hypertension.

Correlation between abnormal thyroid parenchymal echogenicity and thyroid function changes in health examination population / 中华健康管理学杂志

Objective:To explore the relationship between thyroid parenchymal echogenicity abnormalities and thyroid function evolution in health examination population.Methods:It was a cohort study. According to the inclusion and exclusion criteria, participants were selected from individuals who underwent thyroid color ultrasound and thyroid function tests at the Health Management Center of Tianjin Medical University General Hospital from January to December 2017. Data including age, gender, smoking history, alcohol consumption history, personal medical history, and thyroid function re-examination information were collected. Follow-up was conducted until the occurrence of thyroid function abnormalities or until the end of the follow-up period. The cumulative incidence rate and incidence density of thyroid function abnormalities were evaluated. Cox regression analysis was used to analyze the relationship between thyroid parenchymal echogenicity abnormalities and thyroid function evolution.Results:A total of 6 754 participants were included in this study, with an average age of (45.80±12.12) years, and females accounted for 42.7%. The mean follow-up time was 1.82 years, with a cumulative follow-up duration of 12 263 person-years. During the follow-up period, 154 new cases of thyroid function abnormalities occurred, with a cumulative incidence rate of 2.28% (95% CI: 1.94%-2.66%) and an incidence density of 12.56/1 000 person-years (95% CI: 10.66/1 000-14.69/1 000 person-years). The multivariate adjusted Cox regression analysis showed that individuals with thyroid parenchymal echogenicity abnormalities had a significantly increased risk of developing isolated thyroid stimulating hormone abnormalities and thyroid function abnormalities, with HR(95% CI) of 3.09 (2.02-4.73) and 2.92(1.96-4.33), respectively, both P<0.001. Stratified analysis showed that, except for body mass index <18.5 kg/m 2, current smoking, and current alcohol consumption, all other stratified factors showed a significant increase in the risk of thyroid function abnormalities in individuals with thyroid parenchymal echogenicity abnormalities. Conclusion:Thyroid parenchymal echogenicity abnormalities are important risk factors for the evolution of thyroid function abnormalities. Continuous monitoring of thyroid function should be given due attention.
