Progress in diagnosis and treatment of acute injury to the anterior talofibular ligament

Injury to the anterior talofibular ligament(ATFL)is a common acute injury of the lateral foot ligament.Untimely and improper treatment significantly affects the quality of life and rehabilitation progress of patients.The purpose of this paper is to review the anatomy and the current methods of diagnosis and treatment of acute injury to the ATFL.The clinical manifestations of acute injury to the ATFL include pain,swelling,and dysfunction.At present,non-surgical treatment is the first choice for acute injury of the ATFL.The standard treatment strategy involves the“peace and love”principle.After initial treatment in the acute phase,personalized rehabilitation training programs can be followed.These may involve proprioception training,muscle training,and functional exercise to restore limb coordination and muscle strength.Static stretching and other techniques to loosen joints,acupuncture,moxibustion massage,and other traditional medical treatments can relieve pain,restore range of motion,and prevent joint stiffness.If the non-surgical treatment is not ideal or fails,surgical treatment is feasible.Currently,arthroscopic anatomical repair or anatomical reconstruction surgery is commonly used in clinical practice.Although open Broström surgery provides good results,the modified arthroscopic Broström surgery has many advantages,such as less trauma,rapid pain relief,rapid postoperative recovery,and fewer complications,and is more popular with patients.In general,when treating acute injury to the ATFL,treatment management and methods should be timely and reasonably arranged according to the specific injury scenario and attention should be paid to the timely combination of multiple therapies to achieve the best treatment results.

Assessment of physical activity status among pregnant women in southwestern China

Objective: To assess the patterns and intensities of physical activity among pregnant women in southwestern China, which help us create a fitness regimen based on the 2002 American College of Obstetricians and Gynecologists (ACOG) guidelines for exercise during pregnancy. Methods: A cross-sectional study was performed to recruit pregnant women at a prenatal checking visit clinic with the self-administered Chinese version of Pregnancy Physical Activity Questionnaire (PPAQ). Results: A total of 1179 Chinese pregnant women were enrolled, of whom 92.60% were classified as not meeting the ACOG guidelines. By intensity, 47.36% of the score was attributed to light-intensity activities (1.5 to <3.0 metabolic equivalent [MET]) in the first trimester;the other 2 trimesters were similar. By patterns, about 45.15% of the score was attributed to inactivity. More than 82.35% of enrolled pregnant women regarded slowly walking as the most common type of exercise during pregnancy. Conclusions: This study represents a group of Chinese women who maintained an inactive lifestyle, including low-intensity activities and unitary type of exercises during their pregnancy. Health-care providers are advised to provide appropriate physical activity guidelines to pregnant women. Development of MET-hours/week recommendations is warranted to promote greater physical activity during pregnancy.

Value of fasting plasma glucose to screen gestational diabetes mellitus before the 24th gestational week in women with different pre-pregnancy body mass index

Background:Gestational diabetes mellitus(GDM)is usually diagnosed between 24th and 28th gestational week using the 75-g oral glucose tolerance test(OGTT).It is difficult to predict GDM before 24th gestational week because fast plasma glucose(FPG)decreases as the gestational age increases.It is controversial that if FPG≥5.1 mmol/L before 24th gestational week should be intervened or not.The aim of this study was to evaluate the value of FPG to screen GDM before 24th gestational week in women with different pre-pregnancy body mass index(BMI).Methods:This was a multi-region retrospective cohort study in China.Women who had a singleton live birth between June 20,2013 and November 30,2014,resided in Beijing,Guangzhou and Chengdu,and received prenatal care in 21 selected hospitals,were included in this study.Pre-pregnancy BMI,FPG before the 24th gestational week,and one-step GDM screening with 75 g-OGTT at the 24th to 28th gestational weeks were extracted from medical charts and analyzed.The pregnant women were classified into four groups based on pre-pregnancy BMI:Group A(underweight,BMI<18.5 kg/m^2),Group B(normal,BMI 18.5-23.9 kg/m^2),Group C(overweight,BMI 24.0-27.9 kg/m^2)and Group D(obesity,BMI≥28.0 kg/m^2).The trend of FPG before 24th week of gestation was described,and the sensitivity and specificity of using FPG before the 24th gestational week to diagnose GDM among different pre-pregnancy BMI groups were reported.Differences in the means between groups were evaluated using independent sample t-test and analysis of variance.Pearson Chi-square test was used for categorical variables.Results:The prevalence of GDM was 20.0%(6806/34,087)in the study population.FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week.FPG was higher in women with higher pre-pregnancy BMI.FPG before the 24th gestational week and pre-pregnancy BMI could be used to predict GDM.The incidence of GDM in women with FPG≥5.10 mmol/L in the 19th to 24th gestational weeks and pre-pregnancy overweight or obesity was significantly higher than that in women with FPG≥5.10 mmol/L and pre-pregnancy BMI<24.0 kg/m^2(78.5%[62/79]vs.52.9%[64/121],χ^2=13.425,P<0.001).Conclusions:FPG decreased gradually as the gestational age increased in all pre-pregnancy BMI groups until the 19th gestational week.Pre-pregnancy overweight or obesity was associated with an increased FPG value before the 24th gestational week.FPG≥5.10 mmol/L between 19 and 24 gestational weeks should be treated as GDM in women with pre-pregnancy overweight and obesity.

Association between Maternal Weight Indicators and Iron Deficiency Anemia during Pregnancy： A Cohort Study

Background： The effect of maternal weights on the risk of iron deficiency anemia （IDA） during pregnancy remains unclear. The study aimed to investigate the association between maternal weight indicators and IDA during pregnancy. Methods： We conducted a cohort study to examine the association between maternal weight indicators, including prepregnancy body mass index and the rate of gestational weight gain （GWG）, and the risk of IDA among Chinese pregnant women. Data about new-onset IDA at different trimesters from a national cross-sectional survey were collected; information regarding baseline variables and rate of GWG from women participating in the survey were retrospectively collected. Tested IDA and reported IDA were documented. Multilevel logistic regression to examine the association between maternal weight indicators and the risk of IDA after adjusting for potential confounders was conducted. Results： This study enrolled 11,782 pregnant women from 24 hospitals from September 19, 2016, to November 20, 2016. Among those, 1515 （12.9%） IDA events were diagnosed through test （test IDA）： 3915 （33.3%） were identified through test and patient reporting （composite IDA）. After adjusting for confounders and cluster effect of hospitals, underweight pregnant women, compared with normal women, were associated with higher risk of test IDA （adjusted odds ratio [aOR]： 1.35, 95% confidence interval [CI]： 1.17-1.57 and composite IDA （aOR： 1.35, 95% CI： 1.21-1.51）; on the contrary, overweight and obese women had lower risk of test IDA （aOR： 0.68, 95% CI： 0.54-0.86 overweight; aOR： 0.30, 95% CI： 0. 13-0.69 obese） and composite IDA （aOR： 0.77, 95% （71：0.67-0.90 overweight; aOR： 0.34, 95% CI： 0.21-0.55 obese）. The higher rate of GWG was associated with higher risk of IDA （test aOR： 1.86 95% CI： 1.26-2.76; composite aOR： 1.54, 95% CI： 1.16-2.03）. Conclusions： Pregnant women who are underweight betbre pregnancy and who have taster GWG are more likely to develop IDA. Enforced weight control during pregnancy and use of iron supplements, particularly among underweight women, may be warranted.

Difference between 2 h and 3 h 75 g glucose tolerance test in the diagnosis of gestational diabetes mellitus(GDM):Results from a national survey on prevalence of GDM

The possibility of the 2 h oral glucose tolerance test(OGTT)as an alternative to the 3 h OGTT was investigated based on data from a national survey on pregnancy-associated diabetes.Data were retrieved from 4179 pregnant women who had OGTT performed after an abnormal 50 g glucose challenge test(GCT).All of the 4 glucose levels during their OGTT were collected and analyzed.According to American Diabetes Association(ADA)gestational diabetes mellitus(GDM)diagnostic criteria,among the 4179 pregnant women who required OGTT,3429(82.1%)were normal and 750(17.9%)were diagnosed as GDM.If the 3rd h glucose levels were omitted from OGTT,79 cases of GDM(10.5%)would be overlooked.No trend was shown where women with more risk factors were more likely to be overlooked if the 3rd h test was omitted(χ^(2) for trend=0.038,P>0.05).No significant differences were found in the rate of cesarean section(CS),preterm births or macrosomia between the 79 cases and those with normal OGTT results and in the gestational weeks when OGTT was performed.It shows that in order to diagnose one woman with GDM,another 52 pregnant women would have an innocent 3rd h glucose test.Omission of the 3rd h glucose test in OGTT might be reasonable due to its convenience,better compliance and a small number of possibly miss-diagnosed cases,and their pregnancy outcomes have no significant difference from those of normal pregnant women.
