ABSTRACT
Objective:To explore the impact of different referral timing on postponing early-onset pre-eclampsia (PE), postponing severe pre-eclampsia (SPE), reducing SPE severe complications and improving maternal and neonatal outcomes by analyzing the pregnancy outcomes of SPE patients who were referred from primary hospitals to tertiary referral center in the referral system.Methods:The clinical data of 159 SPE patients who were referred from primary hospitals, treated and then terminated their pregnancy in Peking University Third Hospital from January 2020 to October 2021, were observed and analyzed in this clinical observational study. According to the clinical stage of PE at the time of referral, they were divided into four groups: 38 cases were referred after onset of SPE severe complications (SPE-C group), 72 cases were referred after onset of SPE (a-SPE group), 15 cases were referred after onset of PE (a-PE group) and 34 cases were referred after detection of PE early warning-signs (Warn-s group). And then these 159 cases were divided into different color groups according to the project management system for high-risk pregnant women. Patients of Red color (highest risk) and Orange color (higher risk) were required to be referred to tertiary hospitals (Red-Orange group, 113 cases), and patients of Yellow color (high risk) could be treated under tertiary hospitals (Yellow group, 46 cases). The maternal and neonatal outcomes of different referral timings were analyzed and compared.Results:(1) Pregnancy outcomes of different referral timings grouped by PE clinical stage at the time of referral: the later the referral timing, the higher the rate of SPE severe complications, the shorter the interval from referral to termination of pregnancy. The rate of SPE severe complications in the SPE-C group was significantly higher than those of the other three groups, and the interval from referral to termination of pregnancy in the SPE-C group was significantly shorter than those of the other three groups (all P<0.05). The referral gestational age of Warn-s group was earlier than those of the other three groups (all P<0.05). The average gestational ages for onset of SPE, termination of pregnancy, and onset of SPE severe complications were all after 34 gestational weeks, and were later than those of a-SPE group and SPE-C group; the rates of SPE onset before 34 gestational weeks, SPE severe complications onset before 34 gestational weeks, terminating pregnancy before 34 gestational weeks, neonatal intensive care unit (NICU) hospitalization, and pregnancy giving up before 28 gestational weeks were lower than those of a-SPE group and SPE-C group, the length of NICU stay was shorter than those of a-SPE group and SPE-C group, and its rate of take-home-babies was 100%, significantly higher than those in a-SPE group and SPE-C group (all P<0.05). The gestational ages for onset of SPE and termination of pregnancy in a-PE group were later than those in a-SPE group and SPE-C group, the rates of SPE onset before 34 gestational weeks, terminating pregnancy before 34 gestational weeks, and NICU hospitalization were lower than those of a-SPE group and SPE-C group, the length of NICU stay was shorter than those of a-SPE group and SPE-C group (all P<0.05). (2) Pregnancy outcomes of different referral timings grouped by the color classification of PE clinical characteristics: among the 159 cases of SPE, 113 cases (71.1%, 113/159) were in the Red-Orange group which were required to be referred to tertiary hospitals, and 46 cases (28.9%, 46/159) were in the Yellow group,which were not in the range of referral requirements, but actually referred to the tertiary hospital and eventually developed SPE. Gestational ages for onset of SPE, termination of pregnancy, and onset of SPE severe complications in the Yellow group were later than those of the Red-Orange group, while the rates of SPE onset before 34 gestational weeks, SPE severe complications onset before 34 gestational weeks, terminating pregnancy before 34 gestational weeks, NICU hospitalization, and pregnancy giving up before 28 gestational weeks were lower than those of the Red-Orange group, the length of NICU stay was shorter than that of the Red-Orange group, and its rate of take-home-babies was higher than that in the Red-Orange group (all P<0.05). (3) Analysis of different clinical referral timings in the Yellow group: among these 159 SPE patients, 46 cases (28.9%, 46/159) would be excluded from the range of referral requirements which belonged to the Yellow color grade, but 6 cases still developed SPE severe complications (4 cases in Warn-s group and 2 cases in a-PE group), 17 cases were terminated pregnancy before 34 weeks of gestation (12 cases in Warn-s group and 5 cases in a-PE group), and 23 cases developed SPE before 34 weeks of gestation (17 cases in Warn-s group and 6 cases in a-PE group). (4) Multivariate analysis: referral after detection of PE early warning signs was the independent protective factor for postponing the onset of SPE severe complications ( P<0.05). Referral after detection of PE early warning signs and referral after onset of PE were both protective factors for postponing the onset of SPE and early-onset PE (all P<0.05). Conclusions:Different referral timing in the referral system is one of the key points that affect the maternal and neonatal outcomes of SPE. Referral after detection of PE early warning signs and timely referral after onset of PE would reduce early-onset PE, postpone the onset of SPE and reduce the severe complications of SPE. The clinical development and evolution of PE is really complicated, and referral based on specific clinical situations is better than referral based on fixed mode.
ABSTRACT
Objective:To explore the feasibility and key point of improvement in preventing and postponing the onset of severe pre-eclampsia (SPE) and its severe complications in the tertiary referral system by analyzing the clinical characteristics of SPE in a single tertiary referral center.Methods:The clinical data of 217 patients with SPE who were hospitalized and terminated pregnancy in Peking University Third Hospital from January 2020 to December 2020 were retrospectively analyzed. The risk factors, clinical characteristics and severe complications of SPE between the patients referred from primary hospitals (referral group) and the patients received regular prenatal care in the tertiary referral center (central group) were compared, as well as the influence of the referral timing on the characteristics and perinatal outcome.Results:(1) Clinical characteristics: among the 217 cases of SPE, 84 cases were in the referral group and 133 cases were in the central group. The gestational ages at SPE clinical diagnosis [31.5 weeks (28.1-34.6 weeks) vs 35.6 weeks (33.3-37.2 weeks); Z=-6.547, P<0.01], termination of pregnancy [32.3 weeks (29.5- 35.1 weeks) vs 36.3 weeks (34.4-37.5 weeks); Z=-6.554, P<0.01] and onset of SPE severe complications [30.6 weeks (26.4-32.7 weeks) vs 34.9 weeks (32.7-36.5 weeks); Z=-4.040, P<0.01] in the referral group were significantly earlier than those in the central group, the rates of ICU [10.7% (9/84) vs 3.8% (5/133); χ2 =4.126, P=0.042] and neonatal ICU hospitalization [72.9% (51/70) vs 54.7% (70/128); χ2 =6.286, P=0.012] were higher than those in the central group, while the live birth rate [83.3% (70/84) vs 96.2% (128/133); χ2 =10.736, P=0.001] was lower than that of the central group. (2) Analysis of risk factors: for the patient whose risk factors were obesity, advanced age or pre-eclampsia history, the gestational ages at SPE clinical diagnosis and termination of pregnancy in the referral group were significantly earlier than those in the central group ( P<0.05). For those with chronic hypertension, the gestational ages at severe complications onset in the referral group were significantly later than those in the central group ( P<0.05). For those without obvious risk factors, the gestational ages at SPE clinical diagnosis, termination of pregnancy and onset of SPE severe complications in the referral group were earlier than those in the central group ( P<0.05). (3) Analysis of severe complications: the top three severe complications in the referral group and the central group were hypertensive encephalopathy/cerebrovascular accident [20.2% (17/84) vs 7.5% (10/133)], HELLP syndrome [7.1% (6/84) vs 8.3% (11/133)] and placental abruption [8.3% (7/84) vs 7.5% (10/133)]. The rate of hypertensive encephalopathy/cerebrovascular accident in the referral group was significantly higher than that in the central group ( χ2 =7.645, P=0.006). (4) Analysis of referral timings: the timings included referral after onset of SPE severe complications (8.3%, 7/84), referral after onset of SPE (67.9%, 57/84), referral after detection of SPE early warning signs (14.3%, 12/84) and referral after detection of SPE risk factors in the 2nd and 3rd trimester (9.5%, 8/84). The earlier the referral, the longer the interval from clinical diagnosis to onset of severe complications, from referral to termination of pregnancy, and from referral to severe complications onset ( P<0.05). The earlier the referral, the lower the NICU hospitalization rates, the higher the live birth rates. The ICU hospitalization rate of referrals after severe complications onset was significantly higher than those of the other three referral timing groups ( P<0.05). Conclusions:SPE occurs in hospitals of different levels. Although tertiary referral center may postpone the onset of SPE and its severe complications, reduce the severity of SPE and prolong the gestational age, its awareness of prevention and control still needs to be further improved. Early identification of the risk of SPE and timely referral are important parts of improving SPE adverse outcomes in primary medical institutions. The significance and value of referral system need to be brought into full play.
ABSTRACT
Objective@#To observe the dynamic changes of human serum albumin (HSA) level during pregnancy and study the early warning significance of HSA level on the onset of preeclampsia (PE) .@*Methods@#Totally 369 PE pregnant women (PE group) and 309 normal pregnant women (control group) without PE who admitted in Haidian Maternal and Child Health Hospital from January 2013 to December 2017 were selected. HSA levels were tested before meeting the criterion of PE in the first trimester, the early-third trimester and the late-third trimester, the difference between the two groups were compared. The relationship between the HSA level and the incidence of complications in PE patients was analyzed.@*Results@#(1)The mean values of HSA level in PE group and control group were (41.9±3.1) versus (40.0±2.2) g/L, (34.2±2.7) versus (35.4±2.7) g/L and (33.7±2.9) versus (36.7±3.3) g/L in the first trimester,the early-third trimester and the late-third trimester respectively,the difference in the first trimester was no significance (P>0.05), while the differences in the early-third trimester and the late-third trimester were both significant (all P<0.05). (2) The HSA level during pregnancy of PE group showed a continuous downward trend, while the control group was V-shaped trend. The receiver operating characteristic (ROC) curve analysis showed that PE could be early warned by the decrease of HSA level in PE group [area under curve (AUC)=0.742, cut-off value=5.97 g/L, sensitivity 70.8%, specificity 62.8%], the same result was in severe PE (AUC=0.756, cut-off value=6.85 g/L, sensitivity 70.8%, specificity 72.0%). The level of HSA was negatively correlated with the incidence of complications (r=-0.19, P<0.01).@*Conclusions@#Excessive decrease of HSA level is an early warning factor for PE onset. The higher the baseline of HSA level and the greater the extent of pregnancy decline, the risk of PE in pregnant women is higher. The lower of HSA level in PE, the incidence of complications is higher. The excessive decrease of HSA level may be the first clinical manifestation before the onset of clinical symptoms of PE, so it may be the warning factor and one of the laboratory indicators in the PE sub-clinical stage.

ABSTRACT
Objective To investigate the status of nutritional risk and nutritional support in general surgery patients, and to explore their association with postoperative complications and length of hospital stay.Methods From January 2014 to February 2015, 853 inpatients in general surgical wards in the Second Hospital of Hebei Medical University were enrolled.Nutritional Risk Screening 2002 (NRS 2002) was used to estimate nutritional status of patients.The patients were divided into 2 groups based on whether they received nutritional support.The length of hospital stay in days and postoperative complications were recorded.The association of nutritional risk and nutritional support with complications and length of hospital stay were analyzed.Results In the 853 surgery patients, the prevalence of nutritional risk was 31.1％ (265/853) and that of malnutrition was 5.4％ (46/853).The incidence of postoperative complications was 14.2％ (121/853).The patients with nutritional risk had a significantly higher incidence of postoperative complications compared to those without nutritional risk [29.8％ (79/265) vs.7.1％ (42/588) , P ＜ 0.000] , and a longer hospital stay [(12.5 ±6.4) days vs.(4.2 ±3.9) days, P ＜0.001].In the 853 patients, 27.3％ (233/853) received nutrition support.In the patients with nutritional risk, those on nutritional support had a significantly lower incidence of complications compared with those not on nutritional support [16.7％ (32/192) vs.64.4％ (47/73), P＜0.05] and shorter hospital stay [(7.5±4.6) days vs.(16.3±8.5)days, P ＜ 0.05].Conclusions According to NRS 2002 result, a fairly high percentage of general surgery patients may have nutritional risk.Patients with decreased body mass, less dietary intake, and at higher age may be more likely to have nutritional risk.Nutritional risk may be associated with a higher incidence of postoperative complications and longer hospital stay.Patients at nutritional risk appear to be more likely to benefit from nutritional support.
ABSTRACT
Objective To identify the early warning signs of severe preeclampsia (SPE). Methods A case-control (1: 2) observational study was conducted. Forty-seven pregnant women with SPE, who attended the prenatal clinics of Peking University Third Hospital regularly from Jan. 2002 to Dec. 2007, were selected as the study group, including 12 early onset and 35 late onset ones. The control group consisted of 94 healthy singleton pregnant women at the same period. Clinical data were collected and analyzed. Results (1) The basal body mass index (BMI) showed no difference between the study and control group [(23.27±4.31)kg/m2 vs (21.52±3.09)kg/m2, P>0.05]. (2) The net increase of BMI in the study group before the onset of SPE was higher than that in the control [(5.60±2.17)kg/m2 vs (4.85±1.52)kg/m2, P<0.05] and the increase of BMI per week was also higher [(0.74±0.41)kg/(m2*w)-1 vs (0.23±0.18)kg/(m2*w)-1, P<0.01]. The sensitivity and specificity of BMI increase per week in predicting SPE was 84% and 81% at a cut-off value of 0.39 kg/(m2*w)-1, respectively, and 79% and 91% at 0.41 kg/(m2*w)-1 correspondingly. (3) During the third trimester and before the onset of SPE, the weight gain per week in the study group was higher than that of the control [(0.93±0.70)kg vs (0.63±0.20)kg, P<0.01]. Significant difference was also found in the net weight gain between the two groups (P<0.01), but not in the percentage of women with excessive weight gain (>0.50 kg/w) [60%(25/42) in the study group vs 63%(53/84) in the control group, P>0.05]. (4) Higher percentage of women experienced pre-hypertension in the study group than in the controls [17%(8/47) vs 5%(5/94), P<0.01]. (5) In the study group, 53%(25/47) of the women had edema before SPE onset, but the figure dropped to 18% (17/94) in the controls(P<0.01). (6) Eight women in the study group and one in the control group suffered from hypoproteinemia before SPE onset with the average level of plasma albumin of (32.6±1.6)g/L and(38.4±2.1)g/L(P<0.01), respectively. (7) Proteinuria was reported in 10 cases (21%)in the study group and 4(4%) in the controls (P<0.01). (8) Logistic regression analysis showed that the risk factors for SPE included edema (OR=6.16,95%CI:2.29-16.57),pre-hypertension (OR=6.21,95%CI:1.56-24.77),proteinuria (OR=9.68,95%CI:1.86-50.30), and weight gain >0.85 kg/w during the third trimester (OR=11.60,95%CI:3.54-37.97). Conclusions Edema, excessive weight gain,pre-hypertension and hypoproteinemia are early warning signs of SPE. Pregnant women with the above signs required close monitoring during prenatal care.
