Research Progress on Factors Affecting the Blood Concentration of Hydroxychloroquine / 医药导报

Originally used as an antimalarial drug,hydroxychloroquine is now widely used in the treatment of rheumatic immune diseases due to its cost-effectiveness,safety,and efficacy.In addition to its immunomodulatory effects,hydroxychloroquine also exhibits anti thrombotic,anti-hypolipidemic,and anti-hypoglycemic properties.Hydroxychloroquine blood levels are correlated with clinical outcomes and adverse reactions,and can reflect patient compliance.However,due to the complex pharmacokinetic profile of hydroxychloroquine,significant inter-individual differences in blood concentration exist even with the administration of the same dosage.This study investigates the factors affecting the blood concentration of hydroxychloroquine in terms of physiological factors,pathological factors,metabolic enzyme gene polymorphisms,and drug-related factors.The aim is to provide a reference for rational clinical use and the development of individualized dosing.

Influencing factors for efficacy of microvascular decompression in primary trigeminal neuralgia / 中华神经医学杂志

Objective:To analyze the influencing factors for efficacy of microvascular decompression (MVD) in primary trigeminal neuralgia (PTN).Methods:A retrospective study was performed. Clinical data of 178 patients with PTN underwent MVD at Department of Neurosurgery, Affiliated Hospital Affiliated to Nantong University from January 2018 to April 2022 were collected. Efficacy was evaluated according to Brisman's criteria. Differences of MVD efficacy in patients with different clinical characteristics or different neurovascular characteristics were compared. Multivariate Logistic regression was used to analyze the independent influencing factors for MVD efficacy.Results:All patients were followed up for about 2 years; at the last follow-up, 164 patients (92.13%) had good postoperative efficacy (130 were cured, 28 were obvious improved, and 6 were improved); 14 patients (7.87%) had poor postoperative efficacy (10 were ineffective and 4 were relapsed). No significant difference in surgical efficacy was noted among patients with different gender, age, left/right lateral pain, disease courses or pain degrees ( P>0.05). Patients with different contact degrees between the trigeminal nerve and blood vessels, different distances between the trigeminal nerve and blood vessels, and different curvature degrees of the posterior trigeminal nerve had significantly different surgical efficacy ( P<0.05). Multivariate Logistic regression indicated that contact degrees between the trigeminal nerve and blood vessels ( OR=0.233, 95% CI: 0.080-0.675, P=0.007), distances between the trigeminal nerve and blood vessels ( OR=6.991, 95% CI: 3.261-14.984, P=0.000), and curvature degrees of the posterior trigeminal nerve ( OR=0.351, 95% CI: 0.158-0.776, P<0.001) were independent influencing factors for postoperative outcomes. Conclusion:The postoperative efficacy is good in patients with slight contact between the trigeminal nerve and blood vessels, with distance between the trigeminal nerve and blood vessels greater than 1×time median width of the trigeminal nerve (WTN), or with hypotenuse height of the arced trigeminal nerve less than 1/2 WTN.

ObjectiveTo investigate the prevalence and influencing factors of overweight， obesity and central obesity among elderly residents in Xuhui District， and to analyze the epidemiological status of central obesity in elderly people with different body mass indexes. MethodsThe third round of health status and health service utilization monitoring data in Xuhui District was used. The information collected from questionnaire survey and physical examination were analyzed. SPSS 20.0 software was used for χ2 test， trend χ2 test and multinominal logistic regression analysis. Results5 096 survey subjects were included. The prevalence of overweight， general obesity， and central obesity in the residents aged 60 and above in Xuhui District were 34.3%， 6.5%， and 29.2%， respectively. There was gender difference in the rates of overweight， obesity， and central obesity among the residents. The overweight and central obesity rates in males were higher than those in females， while the obesity rate was lower than that in females （P<0.05）. Multinominal logistic regression analysis showed that in comparison with the normal weight non-central obesity group drinking only at party （OR=1.729， 95%CI： 1.184‒2.525）， and hypertension （OR=1.637， 95%CI： 1.305‒2.053）， were highly associated with normal weight with central obesity. Aged 60‒ years （OR=1.589， 95%CI： 1.190‒2.120）， aged 70‒ years （OR=1.763， 95%CI： 1.327‒2.342）， male （OR=1.379， 95%CI： 1.134‒1.676）， hypertension （OR=2.231， 95%CI： 1.878‒2.649）， former smokers （OR=1.437， 95%CI： 1.027‒2.011）， drinking at party only （OR=1.491， 95%CI： 1.107‒2.006）， and drinking ≥3 times per week （OR=1.611， 95%CI： 1.116‒2.325）， were highly associated with overweight combined with central obesity. Aged 60‒ years （OR=3.817， 95%CI： 2.251‒6.474）， aged 70‒ years （OR=3.084， 95%CI： 1.838‒5.175）， hypertension （OR=3.683， 95%CI： 2.753‒4.929）， diabetes （OR=2.085， 95%CI： 1.511‒2.878）， former smokers （OR=1.835， 95%CI： 1.043‒3.226）， were highly associated with compound obesity. Central obesity was found in the elderly residents with different BMI categories， and the rate of central obesity increased with the increase of BMI grade. ConclusionThe prevalence of overweight， obesity and central obesity among the elderly aged 60 years and above in Xuhui District is not optimistic. Attention should be paid to the elderly under 80 years old who are with hypertension and/or diabetes， alcohol consumption， low educational level and not doing physical exercise. Especially for the central obesity population with normal BMI， measures should be taken to prevent and intervene the occurrence of obesity and related diseases.

Fundus screening results and related factors of fundus diseases in 5 307 newborns / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the results of fundus screening in 5 307 newborns and the related factors of fundus diseases.METHODS: A total of 5 307 newborns who underwent fundus screening in our ophthalmology department from January to December 2022 were selected. RetCam III system was used for fundus examination, and abnormal fundus conditions were recorded. The influencing factors of retinal hemorrhage in full-term infants and retinopathy of prematurity(ROP)in preterm infants were analyzed.RESULTS: The incidence of ocular abnormalities in newborns was 27.17%, with the highest incidence of retinal hemorrhage(61.23%), followed by retinal exudation(22.95%), ROP and ROP like retinopathy(10.68%). The incidence of morning glory syndrome(0.21%), albino fundus(0.21%), and permanent fetal vasculature(PFV; 0.28%)was lower. The incidence of eye abnormalities in full-term infants was lower than that in preterm infants(26.30% vs 30.08%, P&#x003C;0.05), and the incidence of retinal hemorrhage and exudation in full-term infants was higher than that in preterm infants(P&#x003C;0.05). The incidence of ROP and ROP like retinopathy in preterm infants was higher than that in full-term infants(P&#x003C;0.05). Natural delivery is a risk factor for retinal hemorrhage in full-term infants(P&#x003C;0.05). Fetal age(32-34, 30-31 wk), birth weight(1 500-2 499, &#x003C;1 500 g), milk powder feeding, and oxygen inhalation are risk factors for ROP in premature infants(all P&#x003C;0.05).CONCLUSION: The incidence of eye abnormalities in newborns at our hospital is relatively high, and early detection of eye abnormalities in newborns can be achieved through fundus screening.

Starting effect of highly active antiretroviral therapy on the incidence of anemia in HIV-infected patients / 上海预防医学

ObjectiveTo investigate the risk factors of anemia in HIV-infected patients receiving highly active antiretroviral therapy （HAART） in the Pudong New Area. MethodsA retrospective cohort study was conducted among HIV-infected patients who started HAART from 2005 to 2020 in Pudong New Area. Cox proportional hazards model was used to analyze the risk factors of anemia， moderate or severe anemia， and chronic anemia. The piecewise linear mixed-effect model was used to analyze the association between initial HAART classes and hemoglobin change in the follow-up. ResultsA total of 2 403 HIV-infected patients were included in the analysis. Among them， there were 357 cases of new onset anemia， 86 cases of chronic anemia and 102 cases of moderate or severe anemia， with the incidence density of 4.41/100 person years， 0.89/100 person years and 0.96/100 person years respectively. Multifactorial Cox regression analysis results showed that female， age >45 years， baseline CD4+ T lymphocyte count （CD4） <200 cells‧μL-1， opportunistic infections， glomerular filtration rate （eGFR） <60 mL‧min-1‧（1.73 m2）-1， and zidovudine （AZT） or protease inhibitor （PIs） based regimens were associated factors for the development of anemia. Female， age >45 years， CD4 <200 cells‧μL-1， opportunistic infections， and AZT-based regimens were associated with the development of chronic anemia. Mild anemia at baseline and AZT-based regimens were associated with the development of moderate or severe anemia. Linear mixed-effects model showed that the use of AZT （-7.87 g‧L-1， 95%CI： -9.42 to -6.32） or PIs （-3.43 g‧L-1， 95%CI： -5.57 to -1.30） was associated with lower Hb at follow-up. ConclusionInitial use of AZT and PIs is associated with progression to anemia and a lower follow-up hemoglobin level. Increased hemoglobin monitoring in users of AZT and PIs may be beneficial， especially during the first 6 months after initiation of HAART.

Clinicopathological analysis of superior mediastinal lymph node metastases in medullary thyroid carcinoma / 中华肿瘤杂志

Objective: To investigate the clinicopathological characteristics of superior mediastinal lymph node metastases (sMLNM) in medullary thyroid carcinoma (MTC). Methods: This retrospective analysis enrolled the patients who were treated for sMLNM of MTC in our hospital from May 2012 to January 2021. All patients were suspected of sMLNM due to preoperative imaging. According to the pathological results, the patients were divided into two groups named sMLNM group and the negative superior-mediastinal-lymph-node group. We collected and analyzed the clinical features, pathological features, pre- and post-operative calcitonin (Ctn), and carcinoembryonic antigen (CEA) levels of the two groups. Logistic regression analysis was used to analyze risk factors, and receiver operation characteristic (ROC) curves were drawn to determine the optimal cut-off values of preoperative Ctn and preoperative CEA for predicting sMLNM. Results: Among the 94 patients, 69 cases were in the sMLNM group and 25 cases were in the non-SMLNM group. Preoperative Ctn level (P=0.003), preoperative CEA level (P=0.010), distant metastasis (P=0.022), extracapsular lymph node invasion (P=0.013), the number of central lymph node metastases (P=0.002) were related to sMLNM, but the multivariate analysis did not find any independent risk factors. The optimal threshold for predicting sMLNM by pre-operative Ctn is 1500 pg/ml and AUC is 0.759 (95% CI: 0.646, 0.872). The sensitivity, specificity, positive predictive value, and negative predictive value of diagnosis are 61.2%, 77.3%, 89.1%, 39.5%, respectively. In patients who underwent mediastinal lymph node dissection through transsternal approach, the metastatic possibility of different levels from high to low were level 2R (82.3%, 28/34), level 2L (58.8%, 20/34), level 4R (58.8%, 20/34), level 3 (23.5%, 8/34), level 4L (11.8%, 4/34). Postoperative complications occurred in 41 cases (43.6%), and there was no perioperative death in all cases. 14.8% (12/81) of the patients achieved biochemical complete response (Ctn≤12 pg/ml) one month after surgery, 5 of these patients were in sMLNM group. Conclusions: For patients who have highly suspicious sMLNM through imaging, combining with preoperative Ctn diagnosis can improve the accuracy of diagnosis, especially for patients with preoperative Ctn over 1 500 pg/ml. The superior mediastinal lymph node dissection for the primary sternotomy should include at least the superior mediastinal levels 2-4 to avoid residual lesions. The strategy of surgery needs to be cautiously performed. Although the probability of biochemical cure in sMLNM cases is low, nearly 40% of patients can still benefit from the operation at the biochemical level.

Analysis of influencing factors of community elderly health services by general practitioners from the perspective of social ecology / 中华医院管理杂志

Objective:To identify the influencing factors for community elderly health services provided by general practitioners (GPs) using the social ecological theory, for reference in improving their participation and satisfaction.Methods:According to the social ecological theory, an ecological model for GPs to carry out community elderly health services was constructed from four levels: public policy ecology, community health service ecology, interpersonal relationship ecology, and individual characteristics ecology of general practitioners. A survey questionnaire was designed with six latent variables: public health policy support, public health service and basic medical service supply, doctor-patient relationship, individual participation and individual satisfaction. The questionnaire was distributed to 220 GPs from 11 primary healthcare institutions in Jiangsu province, China, who were randomly selected between October and November 2021. Exploratory and confirmatory analyses of the model were conducted using AMOS 25.0.Results:A total of 207 valid questionnaires were collected, and all the KMO values of the six latent variables were greater than 0.7, while the composite reliability values and average variance extracted values greater than 0.7 and 0.5, respectively. Both the reliability and validity of the data met the analysis requirements. Exploratory analysis revealed that public health policy support had a direct positive effect on both public health service and basic medical service supply (both effect sizes being 0.37). Public health service had a direct positive effect on doctor-patient relationship, individual participation and individual satisfaction (effect sizes being 0.52, 0.22, and 0.31, respectively). The direct effect of basic medical service supply on doctor-patient relationship was not significant (effect size being 0.03), but it had a direct positive effect on public health service (effect size being 0.46). Doctor-patient relationship had a direct positive effect on individual participation (effect size being 0.51), but its direct effect on individual satisfaction was not significant (effect size being 0.06). Individual participation had a direct positive effect on individual satisfaction (effect size being 0.52). Conclusions:By optimizing the public policy ecosystem, community health service ecosystem, and interpersonal relationship ecosystem, the participation and satisfaction of general practitioners can be systematically improved.

Effect and prognostic factors of OIF and TIP in children with hypospadias / 临床外科杂志

Objective To explore the efficacy and prognostic independent factors of modified island flap(OIF)and urethroplasty(tip)in the treatment of hypospadias in children.Methods The 164 children with hypospadias analyzed retrospectively were treated from February,2013 to February,2021.They were divided into two groups according to the operation method.82 patients in tip group were treated with tip and 82 patients in OIF group were treated with OIF.The treatment effects of the two groups were compared.Then they were divided into two groups according to the cure condition,namely,the good prognosis group(cured by operation,151 case)and the poor prognosis group(not cured by operation,13 case).Independent factors affecting the prognosis of children were analyzed by binary logistic regression.Results The cure rate of OIF group was 96.34％,which was higher than that of the tip group(87.8％),and the incidence of postoperative complications in OIF group was 7.32％,which was lower than that of the tip group(23.17％,P＜0.05).The operation time in tip group(95.95±12.35)min,which was shorter than that of the OIF group(P＜0.05).At the same time,the binary logistic regression analysis showed that the degree of hypospadias and the classification of barcat were the prognostic factors of children with hypospadias.The degree of penis bending,the width of penis head and the method of operation were suspicious factors.Conclusion OIF and tip have good effects in the treatment of hypospadias in children.OIF has a higher success rate,tip has a shorter operation time and fewer postoperative complications.However,the independent factors affecting the prognosis of children are preoperative hypospadias classification and barcat classification.This operation method is not an independent factor affecting the prognosis.

Prognosis and influencing factors in critically ill surgical patients of different feeding into-lerance trajectories: a multicentre study / 中华消化外科杂志

Objective:To investigate the prognosis and influencing factors in critically ill surgical patients of different feeding intolerance trajectories.Methods:The retrospective cohort study was conducted. The clinical data of 354 critically ill surgical patients who were admitted to 69 medical centers in the Chinese Critical Care Nutrition Trials Group -NEED database from March 2018 to July 2019 were selected. There were 247 males and 107 females, aged 58(46,68)years. According to the trajectory model of feeding intolerance change, 354 patients were divided into 3 categories as feeding intolerance, decreased feeding intolerance, continuous feeding intolerance, including 164, 49, 141 cases respectively. Observation indicators: (1) general situations of patients of different feeding intolerance trajectories; (2) treatment of patients of different feeding intolerance trajectories; (3) survival of patients of different feeding intolerance trajectories; (4) analysis of pro-gnostic factors in critically ill surgical patients. Measurement data of normal distribution were expressed as Mean± SD, and one-way analysis of variance was used for comparison between groups. Measurement data of skewed distribution were expressed as M( Q1, Q3), and Kruskal-Wallis rank sum test was used for comparison between groups. Count data were expressed as absolute numbers or percentages, and chi-square test was used for comparison between groups. Ordinal data were compared using the Kruskal-Wallis rank sum test. Bonferroni correction was used for pairwise comparison. Group-based trajectory model was constructed according to Traj plug-in in Stata17.0 statistical software, and the optimal trajectory model was evaluated by Bayesian information criterion and average posterior probability parameter. The Kaplan-Meier method was used to draw the survival curve and calculate the survival rate, and Log-Rank test was used for survival analyses. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. Results:(1) General situations of patients of different feeding intolerance trajectories. Of 354 critically ill surgical patients, 257 cases underwent enteral nutrition and 97 cases underwent enteral plus parenteral nutrition. The acute physiological and chronic health score (APACHEII) was 17(13,21), and the sequential organ failure score (SOFA) was 6(5,8). The modified Critical Illness Nutritional risk score (mNUTRIC) was 4 (2,5), the number of complications was 2(1,3). There were 293, 55 and 6 patients with grade Ⅰ, grade Ⅱ and grade Ⅲ acute gastrointestinal injury (AGI), and there were 224, 17 and 61 patients who were treated with mechanical ventilation, continuous renal replacement therapy and vasoactive drugs, respectively. The incidence of feeding intolerance in 354 patients increased first and then decreased, reaching a peak of 25.42%(90/354) on the third day and 53.67%(190/354) within 7 days. Of 354 critically ill surgical patients, cases with no feeding intolerance, decreased feeding intolerance, continuous feeding intolerance had the APACHE Ⅱ as 16(12,20), 17(14,25), 18(13,22), mNUTRIC as 3(2,5), 4(3,6), 4(3,5), the number of complications as 2(1,2), 2(2,3), 2(2,3). There were 152, 27, 114 cases with grade Ⅰ AGI, 12, 22, 27 cases with grade Ⅱ-Ⅲ AGI, 95, 39, 90 cases with mechanical ventilation. There were significant differences in the above indicators among the three groups ( H=6.14, 13.11, 28.05, χ2=37.96, 7.65, P< 0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance and continuous feeding intolerance had the higher number of complications and grade of AGI ( Z=60.32, 54.69, χ2=39.72, 9.52, P<0.05), patients with decreased feeding intolerance had the higher mNUTRIC scores and ratio of mechanical ventilation ( Z=53.41, χ2=7.59, P<0.05). (2) Treatment of patients of different feeding intolerance trajectories. Cases with prokinetic drugs use and post-pyloric feeding were 36, 13 of patients with no feeding intolerance, 25 and 10 of patients with decreased feeding intolerance, 46 and 19 of patients with continuous feeding intolerance, respectively, showing significant differences in the above indicators among the three groups ( χ2=15.76, 6.20, P<0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance had higher ratio of prokinetic drugs use and ratio of post-pyloric feeding ( χ2=15.60, 6.10, P<0.05). (3) Survival of patients of different feeding intolerance trajectories. The 28-day overall survival rates of patients with no feeding intolerance, decreased feeding intolerance, and continued feeding intolerance were 96.96%, 95.92%, and 87.94%, respectively, showing a significant difference ( χ2=10.39, P<0.05). Further analysis showed a significant difference between patents with no feeding intolerance and patients with continuous feeding intolerance ( χ2=9.19, P<0.05). (4) Analysis of prognostic factors in critically ill surgical patients.

Conclusion:For surgical critically ill patients, patients with continuous feeding intolerance have a higher 28-day mortality than patients with no feeding intolerance, and the continuous feeding intolerance is an independent risk factor for 28-day death in critically ill surgical patients.

Status and influencing factors of enteral nutrition support for preterm infants / 中国小儿急救医学

Premature infants have immature gastrointestinal function and are prone to various comorbidities after birth, which have a great impact on their near and long-term prognosis.Proper nutritional support is the basis of their survival and treatment plan, of which enteral nutrition is the main tool.However, the management of enteral nutrition varies considerably between neonatal facilities worldwide, and the nutritional management of preterm infants varies between physicians.This review summarized and discussed the existing literature on enteral nutrition in preterm infants, to provide a review of the current status of enteral nutrition support in preterm infants in China and abroad and the factors that currently influence the time to achieve adequate enteral nutrition, aiming to provide a reference for improving clinical practice protocols.

Status quo and influencing factors of health self-management ability of scientific and technological workers in Shanxi Province / 中华健康管理学杂志

Objective:To investigate the status quo and influencing factors of health self-management ability of scientific and technological workers in Shanxi Province.Methods:This study was a cross-sectional study. Using the general situation questionnaire and the adult health self-management ability evaluation scale, 467 scientific and technological workers who received physical examination in the First Hospital of Shanxi Medical University from January 2022 to September 2022 were investigated by questionnaire, and their height, weight, body mass index, fasting blood glucose, blood lipids and blood uric acid were collected on the day of physical examination. Multiple linear regression analysis was used to explore the influencing factors of health self-management ability, and Pearson and Spearman correlation analysis was used to analyze the correlation between health self-management ability and examination items.Results:The total score of health self-management ability of 467 scientific and technological workers was (153.7±16.5). The results of multiple linear regression showed that the type of medical insurance, self-assessment of health status, staying up late, and sleep quality were independent influencing factors of health self-management ability ( R2=0.141, adjusted R2=0.120, F=6.771; P<0.001). Health self-management ability was positively correlated with high-density lipoprotein ( r=0.114), behavioral subscale was positively correlated with high-density lipoprotein ( r=0.107), environmental subscale was negatively correlated with uric acid ( r=-0.103), triglyceride ( r=-0.118), and positively correlated with high-density lipoprotein ( r=0.129), and cognitive subscale was negatively correlated with triglyceride ( r=-0.125), all of which were statistically significant ( P<0.05). Conclusions:The ability of health self-management of scientific and technological workers in Shanxi Province belongs to the upper middle level, which is affected by the type of medical insurance, the self-assessment of health status, staying up late, and the quality of sleep. It is suggested that the ability of health self-management of scientific and technological workers can be improved by strengthening their health beliefs, providing a more convenient working environment, reducing the frequency of staying up late, and improving their sleep quality.

Influencing factors of lower urinary tract symptoms in patients with prostate hyperplasia after transurethral holmium laser enucleation / 中华全科医师杂志

A total of 360 patients with prostate hyperplasia underwent transurethral holmium laser enucleation of the prostate in Department of Urology of Jinhua People′s Hospital from July 2019 to December 2022. Among 360 patients, lower urinary tract symptoms occurred one month after operation in 40 cases with an incidence rate of 11.11%. The age, body mass index (BMI), course of disease, nature of disease, preoperative prostate volume, postoperative prostate volume, preoperative IPSS score, postoperative IPSS score, preoperative maximum urine flow rate, postoperative maximum urine flow rate, preoperative residual urine volume, postoperative residual urine volume, postoperative urinary tract infection, operative time, postoperative catheter retention time were compared between patients with lower urinary tract symptoms (study group) and those without (control group). There were significant differences in the course of disease, preoperative prostate volume, preoperative IPSS score, preoperative maximum urine flow rate, preoperative residual urine volume, postoperative urinary tract infection and postoperative catheter retention time between two groups ( t=28.01, 6.35, 8.79, 17.92, 34.84, 11.45;all P<0.05). Multivariate logistic analysis showed that the course of disease, preoperative prostate volume, preoperative IPSS score, postoperative urinary tract infection, and postoperative catheter retention time were independent risk factors for postoperative lower urinary tract symptoms ( OR=6.964, 3.442, 1.944, 4.836, 4.225, 4.894; all P<0.05); while the preoperative maximum urinary flow rate was the protective factor( OR=0.043, P<0.05). The incidence of postoperative lower urinary tract symptoms in patients undergoing transurethral holmium laser enucleation of prostate is high. Effective protective measures should be taken based on the risk factors to reduce the incidence of postoperative lower urinary tract symptoms and to promote the early recovery of patients.

Objective:To analyze the body composition and determinants of gestational diabetes mellitus(GDM), so that to provide basic data for prevent and control GDM further.Methods:All 1 553 pregnant women with GDM (GDM group) at 24-28 weeks of gestation were selected, and 1 298 pregnant women with normal glucose tolerance (NGT) at the same pregnancy were taken as the control group. The general data, body composition test data and 75 g oral glucose tolerance test results of the two groups were collected for statistical analysis. T-test was used for comparison between normal distribution measurement data groups, and counting data were compared χ 2 inspection. Results:The age of GDM group (31.30±4.63) years, the body mass index before pregnancy (21.78±3.11) kg/m 2, and the proportion of body fat content (30.77±5.26)% were all higher than that of NGT Group ((28.42±4.01) years, (20.74±3.04) kg/m 2, (27.76±5.56)%). The proportion of water content (50.46±4.11)%, protein content (13.91±1.27)%, and inorganic salt content (4.90±1.99)%, were lower than that of NGT Group ((52.11±3.97)%, (14.47±1.18)%, (5.71±2.26)%), and there were significant differences between the two groups (t values were 17.84, 9.03, 6.41, 8.67, 7.14 and 5.94, respectively; all P<0.001). The detection rates of advanced age 25.4%(394/1 553), family history of diabetes 23.1%(359/1 553), history of GDM 4.3%(67/1 553), history of polycystic ovary syndrome 0.6%(9/1 553) in GDM group were higher than those in NGT group (7.4%(96/1 298), 11.4%(148/1 298), 0.3%(4/1 298), 0.1%(1/1 298)). There were statistically significant differences between the two groups(χ 2 values were 160.49, 66.36, 46.73 and 5.11, respectively; all P<0.05). The proportion of lean, normal, overweight and obese people in GDM group was 11.5%(179/1 553), 65.8%(1 022/1 553), 18.5%(287/1 553), 4.2%(65/1 553), and 22.6%(293/1 298), 63.0%(818/1 298), 11.4%(148/1 298), 3.0%(39/1 298), respectively. The body fat content in GDM group was 1.9%(30/1 553), 45.5%(707/1 553), 52.6%(817/1 553), and 8.1%(105/1 298), 54.0%(701/1 298), and 37.9%(492/1 298), respectively. The protein content in GDM group was 95.9%(1 489/1 553), 4.1%(64/1 553), 0(0/1 553), and 89.5%(1 162/1 298), 10.5%(136/1 298), 0(0/1 298), respectively. The low, normal and high water content in GDM group were 36.3%(564/1 553), 54.3%(843/1 553), 9.4%(146/1 553), and 22.5%(292/1 298), 58.8%(763/1 298), 18.7%(243/1 298), respectively. There were statistically significant differences in the overall distribution of body mass index before pregnancy and the contents of body water, body fat and protein between the two groups (statistical values were 78.89, 100.21, 43.80 and 92.54, all P<0.001). Logistic analysis showed that old age ( OR=3.462, 95% CI=2.737-4.380), overweight before pregnancy ( OR=1.296, 95% CI=1.031-1.628), family history of diabetes ( OR=2.061, 95% CI=1.676-2.535), history of GDM ( OR=12.688, 95% CI=4.577-35.169), high body fat content ( OR=1.607, 95% CI=1.234-2.092), low water content ( OR=1.493, 95% CI=1.025-2.175) were the risk factors of GDM (all P<0.05). Low body fat content ( OR=0.341, 95% CI=0.151-0.768) was the protective factor of GDM ( P<0.05). Conclusions:In addition to the traditional risk factors such as body mass index before pregnancy, old age, family history of diabetes, and history of GDM, the contents of body water and body fat also played an important role in the occurrence of GDM.

Analysis of the epidemic characteristics of diarrhea cases with Vibrio parahaemolyticus infection in Shanghai from 2017 to 2018 / 上海预防医学

Objective To analyze the infection status and epidemic characteristics of Vibrio parahaemolyticus diarrhea cases in Shanghai in recent years， and to explore its influencing factors and provide a basis for the prevention and control of Vibrio parahaemolyticus infection. Methods Food-borne disease surveillance data in Shanghai from 2017 to 2018 was collected， and the infection status and epidemic characteristics of Vibrio parahaemolyticus were analyzed. χ 2 test and multivariate unconditional logistic regression were used to analyze the factors of Vibrio parahaemolyticus infection. Results Among the food-borne surveillance cases in Shanghai from 2017 to 2018， the positive detection rate of Vibrio parahaemolyticus reached 5.1%， and the positive cases were concentrated in July， August， and September. Those working in the catering industry， migrant workers and workers， and the young and middle-aged people （19‒59 years old） have a high incidence. The results of multivariate analysis showed that dining in Qingpu， Songjiang or Minhang District， occupations of migrant workers and workers， age over 19 years old， the third quarter of a year， and the consumption of aquatic animals and related foods are risk factors for Vibrio parahaemolyticus infection. Conclusion The infection of Vibrio parahaemolyticus in Shanghai is still one of the food-borne diseases that warrant our attention. Strengthening food safety management and supervision， and promoting publicity and education for key populations are important for reducing the risk of infection by this pathogen. At the same time， long-term monitoring of infectious diarrhea cases in this city is necessary to dynamically understand the infection and epidemic characteristics of Vibrio parahaemolyticus ， and adjust the annual prevention and control measures in time.
