ABSTRACT
Abstract Objective: To identify sociodemographic and reproductive risk factors associated with MetS in women in their fourth decade of life. Methods: Cohort study conducted on women born from June 1978 to May 1979 in Ribeirão Preto, Brazil. Sociodemographic, clinical, and obstetric data were collected by interview and clinical evaluation. Univariable and multivariable binomial logistic regression models were constructed to identify the risk factors of metabolic syndrome and the adjusted relative risk (RR) was calculated. Results: The cohort included 916 women, and 286 (31.2%) of them have metabolic syndrome. MetS was associated with lack of paid work (RR 1.49; 95% CI 1.14-1.95), marital status of without a partner (RR 1.33; 95% CI 1.03-1.72), low educational level (less than 8 years of schooling [RR 1.72; 95% CI 1.23-2.41], 8 to 12 years of schooling [RR 1.37; 95% CI 1.06-1.76], when compared with more than 12 years of schooling), and teenage pregnancy (RR 2.00; 95% CI 1.45-2.77). There was no association between MetS, and the other covariates studied. Conclusion: Metabolic syndrome in a population of women in the fourth decade of life was associated with lack of employment, lack of a partner, low educational level, and teenage pregnancy.
ABSTRACT
ABSTRACT Objective: To verify the association between sociodemographic factors and the time until the occurrence of new cases of COVID-19 and positive tests for SARS-CoV-2 in Brazil, during the period from May to November 2020, based on a cohort of Brazilians participating in the COVID-19 National Household Sample Survey. Methods: A concurrent and closed cohort was created using monthly data from the PNAD COVID-19, carried out via telephone survey. A new case was defined based on the report of the occurrence of a flu-like syndrome, associated with loss of smell or taste; and positivity was defined based on the report of a positive test, among those who reported having been tested. Cox regression models were applied to verify associations. The analyzes took into account sample weighting, calibrated for age, gender and education distribution. Results: The cumulative incidence of cases in the overall fixed cohort was 2.4%, while that of positive tests in the fixed tested cohort was 27.1%. Higher incidences were observed in the North region, in females, in residents of urban areas and in individuals with black skin color. New positive tests occurred more frequently in individuals with less education and healthcare workers. Conclusion: The importance of prospective national surveys is highlighted, contributing to detailed analyzes of social inequalities in reports focused on public health policies.
RESUMO Objetivo: Verificar a associação entre fatores sociodemográficos e o tempo até a ocorrência de novos casos de COVID-19 e de testes positivos para Sars-CoV-2 no Brasil, durante o período de maio a novembro de 2020, com base em uma coorte dos brasileiros participantes da Pesquisa Nacional por Amostra de Domicílios COVID-19. Métodos: Foi constituída uma coorte concorrente e fechada utilizando dados mensais da Pnad COVID-19, realizada por inquérito telefônico. Um caso novo foi definido com base no relato da ocorrência de um quadro de síndrome gripal, associado à perda de olfato ou paladar; e a positividade foi definida com base no relato de um teste positivo, entre os que referiram ter sido testados. Foram aplicados modelos de regressão de Cox para verificar associações, considerando a ponderação amostral, calibrada para a distribuição etária, de sexos e de escolaridade. Resultados: A incidência acumulada de casos na coorte fixa geral foi de 2,4%, enquanto a de testes positivos na coorte fixa testada foi de 27,1%. Verificou-se maiores riscos nas regiões Centro-Oeste, Norte e Nordeste, entre mulheres, residentes em áreas urbanas, pessoas com escolaridade até o ensino médio, com a cor da pele declarada como preta e trabalhadores da área da saúde. Indivíduos com menor escolaridade e profissionais de saúde apresentaram maior frequência de novos testes positivos. Novos testes positivos ocorreram com maior frequência em indivíduos com menor escolaridade e trabalhadores da área da saúde. Conclusão: Foram observados riscos desiguais entre os estratos populacionais comparados. Destaca-se a importância da realização de inquéritos nacionais prospectivos na investigação de iniquidades em saúde.
ABSTRACT
ABSTRACT We conducted a spatial case-control study nested in a dengue incidence cohort to explore the role of the spatial and socioeconomic factors in the proportion of symptomatic (cases) and inapparent primary dengue virus infections (controls). Cohort participants were children and adolescents (2 to 16 years of age) at the beginning of the follow-up. Case definitions were, for symptomatic cases, fever plus a positive lab result for acute dengue (NS1, RT-PCR, ELISA IgM/IgG), and for inapparent infection a positive result for dengue IgG (ELISA) in subjects without symptoms and with a previously negative result at baseline. The covariates included sociodemographic factors, residential location, and socioeconomic context variables of the census tracts of residence of cases and controls. We used principal component analysis to reduce the contextual covariates, with the component values assigned to each one based on their residences. The data were modeled in a Bayesian context, considering the spatial dependence. The final sample consisted of 692 children, 274 cases and 418 controls, from the first year of follow-up (2014-2015). Being male, older age, higher educational level of the head of the family and having a larger number of rooms in the household were associated with a greater chance of presenting dengue symptomatic infection at the individual level. The contextual covariates were not associated with the outcome. Inapparent dengue infection has extensive epidemiological consequences. Relying solely on notifications of symptomatic dengue infections underestimates the number of cases, preserves a silent source of the disease, potentially spreading the virus to unaffected areas.
ABSTRACT
ABSTRACT BACKGROUND: Abnormal uterine bleeding (AUB) is a common condition, and the Menstrual Bleeding Questionnaire (MBQ) is used for its assessment. OBJECTIVES: To translate, assess the cut-off point for diagnosis, and explore psychometric properties of the MBQ for use in Brazilian Portuguese. DESIGN AND SETTING: Prospective cohort study including 200 women (100 with and 100 without AUB) at a tertiary referral center. METHODS: MBQ translation involved a pilot-testing phase, instrument adjustment, data collection, and back-translation. Cut-off point was obtained using receiver operating curve analysis. Menstrual patterns, impact on quality of life due to AUB, internal consistency, test-retest, responsiveness, and discriminant validity were assessed. For construct validity, the Pictorial Blood Assessment Chart (PBAC) and World Health Organization Quality of Life - abbreviated version (WHOQOL-BREF) were applied. RESULTS: Women with AUB were older, had higher body mass indices, and had a worse quality of life during menstruation. Regarding the MBQ's psychometric variables, Cronbach's alpha coefficient was > 0.70 in all analyses, high intraclass correlation coefficient was found in both groups; no ceiling and floor effects were observed, and construct validity was demonstrated (correlation between MBQ score, PBAC score, and clinical menstrual cycle data). No difference between MBQ and PBAC scores were perceived after the test-retest. Significant differences were found between MBQ and PBAC scores before and after treatment. An MBQ score ≥ 24 was associated with a high probability of AUB; accuracy of 98%. CONCLUSION: The MBQ is a reliable questionnaire for Brazilian women. The cut-off ≥ 24 shows high accuracy to discriminate AUB.
ABSTRACT
BACKGROUND AND AIM@#Remnant cholesterol (remnant-C) mediates the progression of major adverse cardiovascular events. It is unclear whether remnant-C, and particularly cumulative exposure to remnant-C, is associated with nonalcoholic fatty liver disease (NAFLD). This study aimed to explore whether remnant-C, not only baseline but cumulative exposure, can be used to independently evaluate the risk of NAFLD.@*METHODS@#This study included 1 cohort totaling 21,958 subjects without NAFLD at baseline who underwent at least 2 repeated health checkups and 1 sub-cohort totaling 2,649 subjects restricted to those individuals with at least 4 examinations and no history of NAFLD until Exam 3. Cumulative remnant-C was calculated as a timeweighted model for each examination multiplied by the time between the 2 examinations divided the whole duration. Cox regression models were performed to estimate the association between baseline and cumulative exposure to remnant-C and incident NAFLD.@*RESULTS@#After multivariable adjustment, compared with the quintile 1 of baseline remnant-C, individuals with higher quintiles demonstrated significantly higher risks for NAFLD (hazard ratio [HR] 1.48, 95%CI 1.31-1.67 for quintile 2; HR 2.07, 95%CI 1.85-2.33 for quintile 3; HR 2.55, 95%CI 2.27-2.88 for quintile 4). Similarly, high cumulative remnant-C quintiles were significantly associated with higher risks for NAFLD (HR 3.43, 95%CI 1.95-6.05 for quintile 2; HR 4.25, 95%CI 2.44-7.40 for quintile 3; HR 6.29, 95%CI 3.59-10.99 for quintile 4), compared with the quintile 1.@*CONCLUSION@#Elevated levels of baseline and cumulative remnant-C were independently associated with incident NAFLD. Monitoring immediate levels and longitudinal trends of remnant-C may need to be emphasized in adults as part of NAFLD prevention strategy.

Objective To conduct a retrospective cohort study on the influencing factors of poor prognosis of young and middle-aged patients with pulmonary tuberculosis. Methods Selecting 426 young and middle-aged patients who were diagnosed with pulmonary tuberculosis in our hospital from January to December 2018 as the research subjects. Collecting the social demography information of all patients and the information of potential factors affecting the prognosis (allergy history, smoking history, drinking history, BMI level, disease information, treatment information, etc.) and discussing the factors affecting the prognosis of young and middle-aged pulmonary tuberculosis patients and their effects. Results The average age of 426 patients was (41.93±5.17) years old, the average BMI of them was (21.97±3.15) kg/m2, and an average course of disease of them was (2.76±0.99) years. There was no significant difference in the basic sexual information between men and women. In this study, a total of 128 patients with poor prognosis were retrospectively followed up, including 90 males and 38 females. The detection rate of males was significantly higher than that of females (χ2=16.976, P2=18.850, P2=38.924, P2=127.207, P2=32.566, P2=16.715, P2=17.315, P2=16.976，P1 and P1 and P<0.05; Regular treatment still showed potential protective factors, with an HR of 0.408, P<0.05. Conclusion: Male, emaciated body type, disease course ≥ 5 years, smoking history, number of lung field lesions ≥ 3, presence of pulmonary cavities and comorbidities are potential risk factors, while regular treatment suggests potential protective factors. Conclusion More targeted disease control and management should be implemented for middle-aged and young patients with pulmonary tuberculosis based on the aforementioned influencing factors to improve their prognosis.
ABSTRACT
@#Objective To examined gene mutations in thymic carcinoma (TC) patients and to explore prognostic correlates and potential targets for therapy. Methods We retrospectively included TC patients in Sichuan Cancer Hospital between January 2015 and Febuary 2021.Whole-exome sequencing was performed on tumor tissues from TC patients and their control peripheral blood samples, and the raw data were subjected to bioinformatics analysis and statistical analysis. Results We finally included 24 TC patients with 16 males and 8 females at a median age of 55 (42-74) years. The highest frequency of single nucleotide mutations in this cohort were in the TTN gene (42%), HSPG2 (29%), and OBSCN (29%). Higher frequency of copy number variations occurred in ZNF276 gene (54%, loss), BEND3 (50%, loss), DHODH (50%, loss), and VAC14 (50%, loss). Microsatellite instability (MSI) phenotype was found in 25% of the patients, and the mean tumor mutation burden (TMB) was 9.86. Conclusion This study is the first comprehensive analysis of the mutation profile of thymic carcinoma in China to date. The mutation frequencies of TTN, OBSCN, and ZNF276 genes were high. The biomarker analysis suggests that patients may benefit from immunotherapy and have a long effective survival.
ABSTRACT
Cohort studies play an important role in elucidating the association between risk factors and diseases， and are widely used in etiology research， the assessment of disease prognosis， understanding the natural history of diseases， and the surveillance following the market release of new drugs. The data produced by cohort studies possess great scientific value and can provide essential evidence for public health practice. A well-conceived scientific design is a prerequisite to conducting a cohort study， and the design should focus on aspects such as sample size， selection of exposed and non-exposed populations， follow-up procedures， outcome assessments， research duration， and the choice of analytical indicators and methods. Cohort studies have become an important way to obtain scientific evidence. Internationally renowned population-based cohorts， such as China Kadoorie biobank and the Framingham heart study cohort， have provided a wealth of scientifically valuable evidence for promoting human health. The quality of data produced by a cohort study is extremely important， and a cohort study should continuously incorporate new technologies and methods to provide objective， accurate， and reliable means to determine exposure and outcomes， as well as control for bias. Cohort studies have great potential for application and will continue to provide abundant high-quality scientific evidence for the development of strategies and measures to enhance human health.
ABSTRACT
ObjectiveTo retrospectively analyze the effect of modified Shugan Dingji Decoction （疏肝定悸汤） on the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation. MethodsA retrospective cohort study was conducted using the electronic medical record database of Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine to screen and include patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation from January 1st， 2018， to December 31th， 2021. The included patients were divided into an exposure group and a non-exposure group， each consisting of 100 cases， based on whether they received modified Shugan Dingji Decoction. General information of the patients including age， gender， body mass index， duration of illness and comorbidities， medication history， cardiac structure and function indicators such as left atrial diameter， left ventricular end-diastolic diameter， stroke volume and ejection fraction， and the occurrence of endpoint events assessed through 24-hour dynamic electrocardiography or electrocardiogram to determine the recurrence of paroxysmal atrial fibrillation were collected. Kaplan-Meier （K-M） curves and Log-Rank tests were used to conduct survival analysis on the occurrence of endpoint events in the two groups of patients. Univariate and multivariate Cox regression analyses were used to analyze the impact of various factors on entry into endpoint events. Additionally， a safety assessment was performed by comparing liver and kidney function indicators before and after treatment. ResultsIn the non-exposure group， a total of 49 cases （49.0%） experienced endpoint events， while in the exposure group， there were 26 cases （26.0%）. The Log-rank test indicated significant difference between the two groups （χ2=11.211， P=0.001）. Univariate Cox regression analysis showed that age， duration of illness， hypertension， diabetes， chronic heart failure， left atrial diameter， stroke volume， and the use of modified Shugan Dingji Decoction may be the influencing factors for the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation （P＜0.05 or P＜0.01）. Multivariate Cox regression analysis showed that the risk of endpoint events in the exposure group was significantly lower than that in the non-exposure group （P＜0.01）. Patients with a duration of illness ＞12 months had a significantly higher risk of endpoint events compared to those with a duration of illness ≤12 months （P＜0.01）. Patients without concomitant hypertension had a lower risk of endpoint events compared to those with hypertension （P＜0.05）. Patients with left atrial diameter ＞40 mm had significantly higher risk of endpoint events than those with left atrial diameter ≤40 mm （P＜0.01）. There was no statistically significant difference in liver and kidney function indicators between the two groups before and after treatment （P＞0.05）. ConclusionThe use of modified Shugan Dingji Decoction is a protective factor for patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation， which can help to reduce the recurrence and progression of atrial fibrillation. Long duration of illness， concomitant hypertension， and enlarged left atrial diameter are risk factors for patients to experience endpoint events.
ABSTRACT
ABSTRACT Objective: The national vaccination coverage survey on full vaccination at 12 and 24 months of age was carried out to investigate drops in coverage as of 2016. Methods: A sample of 37,836 live births from the 2017 or 2018 cohorts living in capital cities, the Federal District, and 12 inner cities with 100 thousand inhabitants were followed for the first 24 months through vaccine record cards. Census tracts stratified according to socioeconomic levels had the same number of children included in each stratum. Coverage for each vaccine, full vaccination at 12 and 24 months and number of doses administered, valid and timely, were calculated. Family, maternal and child factors associated with coverage were surveyed. The reasons for not vaccinating analyzed were: medical contraindications, access difficulties, problems with the program, and vaccine hesitancy. Results: Preliminary results showed that less than 1% of children were not vaccinated, full coverage was less than 75% at all capitals and the Federal District, vaccines requiring more than one dose progressively lost coverage, and there were inequalities among socioeconomic strata, favorable to the highest level in some cities and to the lowest in others. Conclusion: There was an actual reduction in full vaccination in all capitals and the Federal District for children born in 2017 and 2018, showing a deteriorating implementation of the National Immunization Program from 2017 to 2019. The survey did not measure the impacts of the COVID-19 pandemic, which may have further reduced vaccination coverage.
RESUMO Objetivo: Inquérito nacional de cobertura vacinal aos 12 e 24 meses de idade foi realizado para investigar as quedas nas coberturas a partir de 2016. Métodos: Amostra de 37.836 nascidos vivos das coortes de 2017 e 2018 residentes nas capitais, Distrito Federal (DF) e 12 cidades com mais de 100 mil habitantes, acompanhados nos primeiros 24 meses por registros nas cadernetas de vacinação. Setores censitários foram estratificados segundo condições socioeconômicas, e o mesmo número de crianças foi incluído para cada estrato. Calcularem-se coberturas vacinais de cada vacina e coberturas completas aos 12 e 24 meses, doses aplicadas, válidas e oportunas. Fatores familiares, maternos e da criança associados à cobertura foram pesquisados. Os motivos para não vacinar analisados foram: contraindicações médicas, dificuldades de acesso, problemas no funcionamento do programa e hesitação vacinal. Resultados: Os resultados preliminares mostram que menos de 1% das crianças não foram vacinadas, as coberturas pelo esquema completo são menores que 75% em todas as capitais e no DF, as vacinas com mais de uma dose perdem cobertura progressivamente, há diferenças entre os estratos socioeconômicos, favoráveis aos estratos mais altos em algumas cidades e aos estratos mais baixos em outras. Conclusão: Houve realmente redução da cobertura vacinal em todas as capitais e no DF para as crianças nascidas em 2017 e 2018, denotando piora na execução do Programa Nacional de Imunizações durante os anos de 2017 a 2019. O inquérito realizado não mensurou os impactos da pandemia de COVID-19 que podem ter reduzido ainda mais as coberturas vacinais.
ABSTRACT
ABSTRACT BACKGROUND: Stroke is a major cause of death and functional disability worldwide. Knowledge of the associated factors is essential for defining education, management, and healthcare strategies. OBJECTIVE: To analyze the association between arrival time at a neurology referral hospital (ATRH) and functional disability in patients with ischemic stroke 90 days after the event. DESIGN AND SETTING: Prospective cohort study conducted at a public institution of higher education in Brazil. METHODS: This study included 241 people aged ≥ 18 years who presented ischemic stroke. The exclusion criteria were death, inability to communicate without companions who could answer the research questions, and > 10 days since ictus. Disability was assessed using the Rankin score (mR). Variables for which associations showed a P value ≤ 0.20 in bivariate analysis were tested as modifiers between ATRH and disability. Significant interaction terms were used for multivariate analysis. Multivariate logistic regression analysis was performed with all variables, arriving at the complete model and adjusted beta measures. The confounding variables were included in the robust logistic regression model, and Akaike's Information Criterion was adopted to choose the final model. The Poisson model assumes a statistical significance of 5% and risk correction. RESULTS: Most participants (56.0%) arrived at the hospital within 4.5 hours of symptom onset, and 51.7% presented with mRs of 3 to 5 after 90 days of ictus. In the multivariate model, ATRH ≥ 4.5 hours and females were associated with more significant disability. CONCLUSIONS: Arrival at the referral hospital 4.5 hours after the onset of symptoms or wake-up stroke was an independent predictor of a high degree of functional disability.
ABSTRACT
ObjectiveTo analyze the effect and possible mechanism of the synergistic treatment with Qingjin Huazhuo Formula （清金化浊方， QHF） on the occurrence of thrombotic events in hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease （AECOPD） and phlegm heat stasis obstructing in the lung syndrome. MethodsIn a retrospective cohort study， 305 AECOPD inpatients with the syndrome of phlegm heat stasis obstructing in the lung were included. According to whether using QHF （the course of treatment ≥ 7 days）， they were divided into the exposure group （193 cases） and the non-exposure group （112 cases）. Totally， 109 pairs of cases were obtained by 1∶1 propensity score matching （PSM）. After matching， the occurrence of thrombotic events during hospitalization， the remission of main symptoms or signs （including cough， expectoration， wheezing， cyanosis） after 10 days （±3 days） of treatment， and the difference of the indicators including D-dimer， percentage of neutrophils （NEUT%）， C-reactive protein （CRP）， arterial partial pressure of oxygen （PaO2）， and arterial partial pressure of carbon dioxide （PaCO2） before treatment and after 10 days （±3 days） of treatment during the first auxiliary examination. ResultsAfter matching， the incidence of thrombotic events during hospitalization in the exposure group （5 cases， 4.59%） were lower than that of the non-exposure group （15 cases， 13.76%， P＜0.05）. The exposure factor that taking QHF for 7 days or above was a protective factor for thrombotic events in AECOPD hospitalized patients with phlegm heat stasis obstructing in the lung syndrome （RR = 0.333， 95% CI 0.126 to 0.885）. The remission rates of cough （100/109， 91.74%）， expectoration （103/109， 94.50%）， wheezing （102/109， 93.58%）， and cyanosis （97/109， 88.99%） in the exposure group were significantly higher than those in the non-exposure group （90/109， 82.57%； 94/109， 86.24%； 89/109， 81.65%； 86/109， 78.90%） after treatment （P＜0.05）. After treatment， the levels of D-dimer， NEUT%， CRP and PaCO2 in both groups significantly decreased （all P＜0.05）， and the level of PaO2 significantly increased （P＜0.05）. The difference of the levels of D-dimer， NEUT% and PaO2 in the exposure group before and after treatment were larger than those in the non-exposure group （P＜0.05）， while the pre-post difference of CRP and PaCO2 were not significantly different between the two groups （P＞0.05）. ConclusionThe synergistic treatment with QHF can effectively reduce the occurrence of thrombotic events， alleviate the clinical symptoms or signs such as cough， expectoration， wheezing， and cyanosis， and can improve lung function in hospita-lized patients with AECOPD and phlegm heat stasis obstructing in the lung syndrome. Its mechanism may be related to improving blood coagulation and inflammatory status.
ABSTRACT
ObjectiveTo explore the relapse status based on the positive and negative syndrome scale （PANSS Scale） and related factors of schizophrenics in Shanghai communities， and to analyze the association between socio demographic characteristics， lifestyles， clinical characteristics and relapse. MethodsA dynamic cohort prospective study design was used in this study. From March 2018 to February 2019， a total of 189 schizophrenics in Xuhui， Hongkou， Changning， Jiading， Songjiang and Baoshan districts were enrolled successively. Baseline questionnaires were conducted through face-to-face interviews at baseline， which contained social demographic information， lifestyle information and clinical information. A follow-up was conducted every 2 weeks for a measurement of PANSS Scale for a total of 6 months. Relapse was assessed by a PANSS score increase of ≥25% from baseline （or an increase of 10 points or more if the baseline score was ≤40 points）. Univariate and multivariate Cox regression models were used to analyze the associations between relapse status （assessed by PANSS Scale） and socio demographic characteristics， lifestyles， and clinical characteristics， respectively. ResultsA total of 165 community schizophrenics completed baseline and follow-up surveys， with a loss to follow-up rate of about 12.7%. After exclusion of sociodemographic and clinical information deficits， 132 patients were included in the analysis totally， with an average age of 48.18±12.67 years， among whom 41.67% were male. Totally 33 patients relapsed during the 6-month follow-up period， with a relapse rate of 25.0%. After adjusting for gender， family history， age， employment， education， marital status， smoking， drinking， exercise frequency， medication compliance， insight， social function， violence history， stress recent events， adverse drug reactions and baseline scores of PANSS Scale， risk factors of relapse included the following four factors： age below 40 years （HR=4.47， 95%CI： 1.15-17.40）， primary school or below （HR=7.11， 95%CI： 1.54-32.83）， unemployed （HR=8.34， 95%CI： 1.78-38.98）， and adverse drug reactions （HR=5.02， 95%CI： 1.75-14.37）. ConclusionWe should pay attention to the risk factors such as age， education， employment and adverse drug reactions， in order to identify high-risk patients and to conduct timely interventions during the relapse management of schizophrenics in Shanghai community.
ABSTRACT
OBJECTIVE@#To analyze the factors related to pregnancy of endometriosis and whether Chinese herbal medicines (CHMs) can improve pregnancy outcomes in patients with endometriosis in long-term management.@*METHODS@#This multicenter cohort study retrospectively analyzed the clinical data of endometriosis patients with fertility needs from January 2019 to November 2019. A total of 252 patients with endometriosis from 5 level-III Grade A hospitals in Beijing were included in this study. Univariate and multivariate logistic regression analysis were performed for the relevant factors. The propensity score matching (PSM) function of SPSS software was used to match the CHMs group with the non-CHMs group. The pregnancy rate and live birth rate were analyzed.@*RESULTS@#The results of univariate analysis showed that age, disease course, presence of infertility, presence of adenomyosis, time after surgery or use of gonadotropin-releasing hormone agonist (GnRH-a), use of CHMs and follow-up time were influencing factors of pregnancy in endometriosis patients (P<0.05). The results of multivariate analysis showed that age, presence of adenomyosis, time after surgery or use of GnRH-a, use of CHMs and follow-up time were independent factors affecting pregnancy in endometriosis patients, among which, age ⩾35 years old, presence of adenomyosis and follow-up time >6 months were independent risk factors (OR=0.445, 0.348, 0.140, respectively, P<0.05), time after surgery or use of GnRH-a ⩽6 months and use of CHMs were independent protective factors (OR=3.839, 3.842, respectively, P<0.05). After PSM, 99 pairs of two groups were matched successfully. The pregnancy rate of the CHMs group was higher than that of the non-CHMs group [55.56% (55/99) vs. 36.36% (36/99), P<0.05]. The live birth rate of the CHMs group was higher than that of the non-CHMs group [49.49% (49/99) vs. 35.35% (35/99), P<0.05].@*CONCLUSION@#CHMs can effectively improve clinical pregnancy rate and live birth rate of patients with endometriosis in the chronic disease management.

Background Changes in cognitive function exist before the onset of clinical Parkinson's disease. However, studies on association between cognitive function and prodromal Parkinson's disease (pPD) are limited. Objective To estimate probability of pPD and assess its association with global and domain cognitive function in Chinese elders. Methods Data were drawn from the Community-based Cohort Study on Nervous System Disease 2018 (baseline) and 2020 (follow-up). We selected 3911 residents aged 55 and above who participated the two waves, without Alzheimer's disease and Parkinson's disease, and with completed information on demographics, disease history, cognitive function test, and risk factors of Parkinson's disease. Cognitive function was assessed using the Chinese version of Montreal Cognitive Assessment Scale. Calculation of probability of pPD and assessment of possible (probability between 30% and <80%) or probable (probability ≥80%) pPD were performed according to the criteria published by the International Parkinson and Movement Disorder Society. Multiple linear regression model was employed to analyze the association between baseline cognitive function and follow-up probability of pPD. Results The medians of scores of baseline global cognitive function and cognitive domains in terms of memory, execution, visuospatial function, language, attention, and orientation were 23, 12, 9, 6, 5, 14, and 6, respectively. The median of follow-up probability of pPD was 0.87%, and the proportion of participants with possible or probable pPD was 0.4%. The differences in the distribution of follow-up probability of pPD were significant in groups by baseline global cognitive score quartiles (χ2=21.68, P<0.001). A higher baseline global cognitive score was considerably related to a lower follow-up probability of pPD, b(95%CI)=0.994(0.988~0.999), P=0.040. After adjusting for selected confounders, the results of multiple linear regression analyses showed that the probability of pPD in the highest quartile group was decreased by 10.7% (b=0.893, 95%CI: 0.794-0.992, P=0.034) relative to the lowest quartile group, and the trend was significant (trend P=0.031). Higher baseline index scores of execution, attention, and orientation were highly related to a lower follow-up probability of pPD (all P<0.05). Conclusion Declines in global cognitive function and cognitive domains of execution, attention, and orientation may associate with a higher probability of pPD in middle-aged and elderly population, which suggests the significance of cognitive intervention in early stage for pPD prevention.
ABSTRACT
Background There is a lack of research evidence on the association between sugar-sweetened beverage (SSB) consumption and gestational diabetes mellitus (GDM) in China. Objective To explore the association between frequency of SSB consumption before pregnancy and risk of GDM in pregnant women in Shaanxi Province, and to provide a scientific basis for targeted interventions to control maternal blood glucose. Methods The recruitment to the China Birth Cohort study started in October 2020. Pregnant women at 6-16 weeks who had their first prenatal examination at five hospitals in Shaanxi Province were recruited. A maternal health questionnaire was used to collect basic information about pregnant women. A semi-quantitative food frequency questionnaire was used to collect the consumption of carbonated beverages, fruit and vegetable juice beverages, coffee beverages, and milk tea beverages in one year before pregnancy, which were summed to obtain the SSB consumption. Pregnant women were divided into three groups according to SSB consumption, namely <1 serving·week−1, 1-4 servings·week−1, and ≥5 servings·week−1. GDM was confirmed by oral glucose tolerance test (OGTT) between 24-28 weeks of gestation. A binary logistic regression model was applied to explore the association between SSB consumption and risk of GDM. Multiple linear regression was applied to investigate the associations between SSB consumption (per 1-serving·d−1 increase) and OGTT fasting plasma glucose, 1-hour glucose, and 2-hour glucose. Results A total of 3811 pregnant women were finally enrolled in this study, of which 752 developed GDM, with an incidence rate of 19.7%. The incidence rates of GDM in pregnant women with SSB consumption frequency of <1 serving·week−1, 1-4 servings·week−1, and ≥5 servings·week−1 were 18.0%, 21.1%, and 26.8%, respectively. After adjusting for maternal age, pre-pregnancy body mass index (BMI), education, number of children born, family history of diabetes, smoking, alcohol consumption, physical activity level, and total energy intake, the risk of GDM increased by 26% (OR=1.26, 95%CI: 1.05, 1.50) in the 1-4 servings·week−1 group and by 76% (OR=1.76, 95%CI: 1.31, 2.38) in the ≥5 servings·week−1 group compared to the <1 serving·week−1 SSB consumption group, respectively. Further stratified analysis revealed no interaction effect (Pinteraction>0.05) between SSB consumption and maternal age, pre-pregnancy BMI, or first labor or not. For each additional SSB consumption per day, the risk of GDM increased by 94% (OR=1.94, 95%CI: 1.37, 2.75); and the maternal OGTT 1-hour glucose and 2-hour glucose increased by 0.33 mmol·L−1 and 0.18 mmol·L−1, respectively (P<0.05), and no significant increase in fasting plasma glucose was found (P>0.05). Conclusion Higher SSB consumption before pregnancy increases the risk of GDM in pregnant women.
ABSTRACT
@#Objective To investigate the application of enhanced recovery after surgery (ERAS) in da Vinci robotic McKeown surgery for esophageal cancer. Methods Clinical data of patients admitted to the First Hospital of Lanzhou University and undergoing da Vinci robotic McKeown surgery for esophageal cancer from 2017 to 2021 were retrospectively analyzed. According to the treatment, they were divided into two groups, a conventional group and an ERAS group. Patients in the conventional group were treated with the conventional perioperative treatment mode of thoracic surgery, and patients in the ERAS group were treated with accelerated rehabilitation surgical treatment mode. Relevant hospitalization indicators and postoperative complication rates were compared between the two groups. Results Finally 128 patients were collected, including 106 males and 22 females, with an average age of 61.91 years. There were 71 patients in the conventional group and 57 patients in the ERAS group. The postoperative pain index in the ERAS group was significantly lower than that in the conventional group (P<0.05), and the duration of postoperative analgesic pump used in the ERAS group was shorter than that in the conventional group (2.39±0.49 d vs. 3.13±0.63 d, P<0.001). There was no statistical difference in the incidence of postoperative related complications (gastroesophageal reflux, anastomotic stenosis, anastomotic fistula, arrhythmia, recurrent laryngeal nerve injury, chylothorax, anastomosis stomatitis or incisional infection) between the two groups (P>0.05), but the incidence of postoperative lung infection in the ERAS group was statistically lower (12.28% vs. 26.76%, P=0.043), and the volume of postoperative pleural effusion was statistically less compared with the conventional group (P<0.05). In the ERAS group, the surgery time (294.35±15.19 min vs. 322.79±59.09 min, P<0.001), postoperative exhaust time (1.44±0.39 d vs. 1.94±0.43 d, P<0.001), postoperative removal time of nasolasal tube (6.79±0.73 d vs. 8.21±0.86 d, P<0.001), hospital stay (19.88±3.36 d vs. 21.34±3.59 d, P=0.020), hospitalization costs (105 575.28±8 960.75 yuan vs. 137 894.64±19 518.60 yuan, P<0.001) were all lower or shorter than those of the conventional group. Postoperative activity was longer in the ERAS group than that in the conventional group (P<0.05), but there was no statistical difference in preoperative anesthesia time between the two groups (P=0.841). Conclusion The application of ERAS in da Vinci robotic McKeown surgery for esophageal cancer can effectively alleviate the physiological and psychological burden of patients, reduce the occurrence of postoperative related complications, effectively shorten the total hospital stay, save hospitalization costs, and reduce the economic burden of patients and society. Therefore, it can be promoted and applied in the clinic.
ABSTRACT
@#Objective To explore the application of Body Tom® mobile CT combined with basic anesthesia in preoperative painless positioning of small pulmonary nodules, and evaluate its safety and effectiveness. Methods Patients using mobile Body Tom® CT to accurately locate pulmonary nodules in the Department of Thoracic Surgery of Affiliated Nanjing Brain Hospital, Nanjing Medical University from August to October 2022 were retrospectively included. Clinical data of the whole patient group were analyzed. Results We finally included 30 patients with 12 males and 18 females at age of 23-71 years. The position success rate of 30 patients with small pulmonary nodules was 100.0%. Location time was 14.20±4.07 min. There was one patient of intrapulmonary hemorrhage, with no other complications such as pneumothorax, positioning needle shedding, or pleural reaction. The time from the end of positioning to the start of surgery was 12.63±5.68 min. There was no needle migration or indocyanine green overflow. All patients completed resection of small pulmonary nodules under single-port thoracoscopy, no transit to opening chest. The average operation time was 85.32±12.60 min. There was no postoperative complications, and the average postoperative chest tube retention time was 2.12±1.34 days. And the average length of hospital stay was 3.52±1.45 days. The postoperative pathological results showed that the distance from the nodules was greater than 2 cm. Conclusion Body Tom® mobile CT combined with basic anesthesia can achieve the preoperative painless, precise positioning of pulmonary nodules, effectively reduce the incidence of preoperative positioning complications, shorten the operation waiting time, ensure the safety and effectiveness of patients with preoperative pulmonary nodules positioning, and further improve the surgical comfort of patients, which has certain clinical application value.
ABSTRACT
@#Objective To investigate the relationship between miR-3187-5p in peripheral blood and pericardial drainage after coronary artery bypass grafting (CABG) and postoperative atrial fibrillation (POAF). Methods Patients who underwent CABG in the Heart Center of Beijing Chao-Yang Hospital from March to May 2022 were enrolled. Peripheral blood and pericardial drainage were collected at 0 h after surgery (immediate time for patients to return to ICU from operating room) to detect miR-3187-5p, and perioperative confounding factors were also collected. The miR-3187-5p was measured by quantitative real-time PCR and its regulated target genes were analyzed by bioinformatics. Results A total of 15 patients were enrolled, including 9 males and 6 females with an average age of 65.6±8.2 years. The incidence rate of POAF was 40.0%. miR-3187-5p in pericardial drainage at 0 h after surgery was an independent predictor for POAF. A total of 1 642 target genes of miR-3187-5p were predicted. GO function enrichment analysis and KEGG signal pathway enrichment analysis showed that target genes of miR-3187-5p were enriched in TGF-β, MAPK, Wnt and other classical collagen metabolic signal pathways, which might activate collagen metabolism by negatively regulating SMAD6 and other inhibitors of the pathways. Conclusion This study is the first to find that miR-3187-5p in pericardial drainage at 0 h after surgery is a potential, novel, and predictive factor for POAF, which may be related to the regulation of myocardial fibrosis signal pathways like TGF-β, MAPK and Wnt pathways, promoting the early collagen metabolism imbalance after CABG, increasing the collagen deposition in the atrium, and then promoting the early structural reconstruction after CABG and leading to the occurrence of POAF. The result provides a research basis for the accurate prediction and prevention of clinical POAF.
ABSTRACT
@#Objective To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001). Conclusion TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.
