OAC,defined as OAC in adults aged under 50 years,has been observed.It is unclear whether survival outcomes for early-onset OAC patients differ from older age groups.AIM To investigate survival outcomes in early-onset OAC patients.METHODS Ovid Medline and Embase were searched from inception to January 2022 for relevant studies relating to early-onset OAC and survival outcomes.Results regarding the overall five-year survival and risk of death of younger and older patients with OAC were extracted and pooled using meta-analyses to produce pooled estimates and 95%CIs where possible.RESULTS Eleven studies which compared survival of early-onset OAC,defined as age at diagnosis of<50 years,with older patients were included.A narrative review of median and mean survival demonstrated conflicting results,with studies showing early-onset OAC patients having both better and worse outcomes compared to older age groups.A meta-analysis of five-year survival demonstrated similar outcomes across age groups,with 22%-25%of patients in the young,middle and older age groups alive after five years.A meta-analysis of four studies demon-strated that early-onset OAC patients did not have a significantly increased risk of death compared to middle-aged patients(hazard ratio 1.12,95%CI:0.85-1.47).INTRODUCTION There is concern that the incidence of oesophageal adenocarcinoma(OAC)in patients under 50,described as early-onset OAC,is increasing.However,data regarding survival of younger patients with OAC is sparse.Globally,while increasing age remains a major non-modifiable risk factor for cancer,the incidence of early-onset cancers,largely accepted to be in adults aged under 50 years,is increasing[1].This includes an observed increase in the incidence of gastrointestinal malignancies such as colorectal,oesophageal,gastric and hepatobiliary cancers[2-4].Despite oesophageal squamous cell carcinoma(OSCC)being more common globally(88%of cases)[5],a striking increase in oesophageal OAC incidence has been reported in developed countries,such as the United States and Europe[6,7].Worryingly,the United Kingdom has the highest incidence of OAC cases in the world[8].In addition to the increase in OAC,an increase in incidence of early-onset OAC,defined as OAC in adults aged under 50 years,has been observed[9,10].A population-based cohort in the Netherlands,consisting of 59584 patients,demonstrated the incidence of early-onset OAC to have tripled from 1989 to 2018,while OSCC cases declined in this age group[7].OAC usually develops in the lower third of the oesophagus and the gastro-oesophageal junction,with risk factors including obesity and gastro-oesophageal reflux disease[11].A poor prognosis is observed,with the overall five-year survival rate for oesophageal cancer between 15%-20%,even with treatment[12,13].These low survival rates are likely due to a combination of late diagnosis,intrinsic resistance to systemic therapy and the limited efficacy of surgical resection.Younger patients tend to present at a more advanced stage at diagnosis compared to those diagnosed later in life.A single centre,retrospective study found that 33.3%of patients in the younger age category(<50 years old)presented with stage IV OAC,compared to the 20.6%of the oldest age category(>70 years old)[14].Another population-based study in the Netherlands observed that OAC patients under 50 years old also presented with distant metastasis more often in comparison to older patients(50.5%vs 44.7%),and that tumour differentiation also varied between age groups[15].Reports of survival estimates in patients with early-onset OAC compared with older patients have resulted in contrasting findings to date.Some studies report that due to the advanced stage and aggressiveness of the tumours seen that the prognosis of these patients is almost always worse than their older counterparts[16].In contrast,another study found that the overall survival,as well as stage-specific survival was higher in those who were younger[17].A Dutch study which included only resectable cases found no difference in 5-year disease specific survival[18].Given the conflicting evidence to date,the aim of this systematic review was to investigate survival in OAC patients according to age at diagnosis.A protocol was composed,and the reporting of this systematic review designed,using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines[19].The protocol included:The review question,search strategy,inclusion criteria,type of quality assessment,the strategy for data analysis,and the‘population,intervention,comparator,and outcome’criteria.These are expanded below.展开更多

Methods: Forty cases of patients with preeclampsia admitted to our hospital between January 2023 and January 2024 were divided randomly into a control group and an observation group of 20 cases each. The control group applied progesterone to preserve the fetus, and the observation group applied dydrogesterone. The symptom relief time, hormone levels before and after treatment, as well as adverse drug reactions, and the effect of fetal preservation between the two groups were compared. Results: The time to relieve vaginal bleeding, abdominal pain. and lumbago in the observation group was shorter than that in the control group (P < 0.05). After treatment, the progesterone levels and incidence of adverse drug reactions in the observation group were lower than those in the control group (P < 0.05). The success rate of fertility preservation in the observation group was higher than that in the control group (P < 0.05). Conclusion: In the treatment of fetal preservation of preeclampsia, the application of dydrogesterone positively alleviated vaginal bleeding, abdominal pain, and lumbago, with mild adverse reactions and a good effect on fetal preservation.展开更多

Early-onset preeclampsia (EOP), which occurred before 34 weeks, proved to be the deadliest. Indeed, it is characterized by a poor maternal and fetal prognosis. EOP has a disparate incidence in the world varying between 0.9% and 31%. Several risks factors are associated with the occurrence of EOP, which is responsible of several adverse obstetrical outcomes. Complications can affect up to 85% of pregnant women with EOP, especially when EOP appears very early, before 28 or even 25 weeks’ gestation. Objectives: To determine frequency of EOP at the University Clinics of Kinshasa, to describe sociodemographic and clinical characteristics of pregnant women with EOP and to identify its risks factors and its association adverse obstetrical outcomes. Methods: The study will be a cross-sectional analytical study in University Clinics of Kinshasa from January 2016 to December 2022. The minimal size will be 119. Our study population will consist of pregnant women who consult for antenatal best care and are neonates in our Clinic. Result will be presented as percentage proportion. Comparison and proportion means between groups will be made using Student’s test and Pearson’s chi-square test, respectively. Our test will be statistically significant for a p-value ≤ than less 0.05. Data will be collected and analysed anonymously and confidentiality. Conclusion: We believe that our study should enable us to identify profile of gestational carriers at risk of EOP in our environment, as well as prognosis associated with this entity, with a view to arousing particular interest in EOP.展开更多

There are few published data on the association between transmembrane serine protease 6 (TMPRSS6) gene polymorphism and preeclampsia. Objective: To assess the association between TMPRSS6 gene polymorphism rs855791SNP in women with preeclampsia compared with healthy pregnant women. Method: A case-control study (60 women in each arm) was conducted at Saad Abuaela Maternity Hospital in Khartoum, Sudan. Sociodemographic and clinical data were gathered through a questionnaire. The participant was genotype for TMPRSS6 gene rs855791SNP using Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP). The results were confirmed by DNA sequencing. Result: There was no significant difference in the median of age, parity, and body mass index. The distribution of the genotypes and alleles of TMPRSS6 rs855791 was consistent with the HWE. The overall TMPRSS6 rs855791 polymorphism was not significantly associated with preeclampsia. However, the proportion of heterozygotes (TC) was considerably higher in the women with preeclampsia (46.7%) than in the control group (23.3%) (p = 0.001;OR = 2.71;95% CI = 1.21 - 6.07). The proportion of homozygotes (TT) and T alleles was not significantly different between women with preeclampsia and the control group. Conclusion: The overall TMPRSS6 rs855791 polymorphism was not significantly associated with preeclampsia and healthy control.展开更多

Maternal sensitivity to the PE gene and the genetic variations of FoxP3 has not been thoroughly investigated. Objective: Investigation of the immune-histochemical expression of FoxP3 in placental tissue of PE patients. Methods: A total of 26 pre-eclamptic women as a case and 26 ethnically matched healthy pregnant women as a control group aged between 18 and 40 years old of different gravidity and parity referred to the labor ward for delivery either by vaginal delivery or cesarean section was enrolled to investigate the immunohistochemical expression of FOXP3 in placental tissue of PE patients. Results: Lower expression of FOXP3 IHC was statistically significant and noted in the group of preeclampsia compared to the healthy control group. Lower gestational age at delivery and a higher percentage of cesarean section were statistically significant and noted in the group of preeclampsia compared to the healthy control group. Conclusion: In comparison to the healthy control group, preeclampsia patients had statistically significantly lower FOXP3 IHC expression, and FOXP3 polymorphism was associated with the development of PE. Our findings can serve as a guide for statistical analyses and functional investigations that are more in-depth.展开更多

Preeclampsia is a public health problem due ...Background: Knowledge of temporal evolution of preeclampsia (PE) in its various aspects is essential in strategies to reduce maternal and perinatal morbidity and mortality. Preeclampsia is a public health problem due to maternal mortality associated with it worldwide (5.6%). Improving quality of its management is a major challenge in low-income countries where, despite progress made in this field, PE remains a major factor in maternal morbidity and mortality. Objective: To evaluate temporal evolution of frequency, risk factors and complications of PE at the University clinics of Kinshasa (UCK). Methods: Descriptive and cross-sectional study concerning minimum simple size of 119 pregnant women who consulted for antenatal care at the University clinics of Kinshasa from January 2012 to December 2022. Results will be reported as percentage proportion, mean and standard deviation. Comparison of proportion and means between groups will be made using Student’s t-test and Pearson’s chi-square test, respectively. The test will be statistically significant for a p value ≤ less than 0.05. Data will be collected and analysed anonymously and confidentially. Conclusion: This study will allow us to evaluate the effectiveness of different prevention and treatment modalities used over time in management of preeclampsia in our setting.展开更多

The two diseases have pathophysiologic similarities in the placenta such as placenta ischaemia, endothelial dysfunction and production of pro-inflammatory cytokine. Yet, there is paucity of studies on the association of these two disease processes. Determining the association between the two disease processes may help to unravel the pathogenesis of preeclampsia and also help in its prevention and patient management. Objective: Determined the association between placenta malaria parasitemia and preeclampsia/eclampsia among parturients at Alex Ekwueme Federal University Teaching Hospital Abakaliki. Materials and Methods: This was a case control study that was conducted in the Labour wards of department of Obstetrics and Gynaecology, Alex Ekwueme Federal University Teaching Hospital Abakaliki (AEFUTHA) and Mile 4 Missionary Hospital Abakaliki, a comprehensive health care centre in Abakaliki, Ebonyi state. It was conducted over a period of 6 months between 1<sup>st</sup> October 2021 and 31<sup>st</sup> March, 2022. The cases in this study were parturients that developed preeclampsia/eclampsia in the course of pregnancy, while the controls were parturient without preeclampsia/eclampsia. Interviewer-administered questionnaires were used to collect data on socio-demographic characteristics, obstetrics and medical histories. Histological examinations were conducted to isolate plasmodium falciparum parasites from placenta samples obtained from the maternal surface of the placenta. The data was processed using Epi Info software. Categorical variables were analyzed using Mc Nemar X<sup>2</sup> test, with a p-value of 0.05 considered statistically significant. Logistic regression models were used to estimate the odds ratios (OR) and 95% CI of the association between placenta malaria parasites and preeclampsia/eclampsia was conducted. Relative risk with 95% CI was used to determine both fetal and maternal outcomes. Results: The prevalence of preeclampsia during the study period was 2.9%. Placenta malaria was positive in twenty one (21) of the 67 cases of preeclampsia/eclampsia analyzed, giving a prevalence of 31.3% and in eleven (11) out of 68 controls (normotensive) patients analyzed, giving a prevalence of 16.2%. The presence of placenta malaria significantly increased the odds of developing preeclampsia/eclampsia among parturients (OR = 2.4, 95% CI = 1.0 - 5.4, P value = 0.04). Presence of placenta malaria in mothers with preeclampsia/eclampsia was associated with adverse pregnancy outcomes such as cerebrovascular accident (RR = 19.2, 95% CI = 1.1 - 341.7, P value = 0.04), DIC (RR = 10.9, 95% CI = 1.4 - 88.0, P value = 0.02), abruptio placenta (RR = 2.4, 95% CI = 1.2 - 4.8, P value = 0.01), pulmonary edema (RR = 2.7, 95% CI = 1.1 - 25.9, P value = 0.03), IUGR (RR = 2.1, 95% CI = 1.1 - 4.5, P value = 0.03) and IUFD (RR = 3.8, 95% CI = 1.3 - 11.7, P value = 0.02). Presence of placenta malaria also increased the risk of NICU admission (RR = 2.6, 95% CI = 1.1 - 6.0, P value = 0.03), Low 1<sup>st</sup> minute APGAR score (RR = 2.7, 95% CI = 1.2 - 6.1, P value = 0.02) and Low 5<sup>th</sup> minute APGAR score (RR = 3.0, 95% CI = 1.0 - 8.6, P value = 0.04) among neonates delivered by mothers with preeclampsia/eclampsia. However, presence of placenta malaria did not significantly increase maternal and perinatal mortalities. Conclusion: There is a higher prevalence of placenta malaria among mothers with preeclampsia/eclampsia when compared with normotensive controls and this was associated with increased risk of certain maternal and perinatal morbidities. Placental malaria was not associated with increased risk of either maternal or perinatal mortality.展开更多

文摘BACKGROUND Early-onset preeclampsia significantly increases maternal and fetal morbidity and mortality.Many pregnant women with early onset preeclampsia choose cesarean section as their delivery method.Although extensive research has explored the association between postpartum depression(PPD)and cesarean section,few studies have investigated the risk factors after cesarean section in women with early-onset preeclampsia.AIM To examine these risk factors through a retrospective,observational analysis of 287 women who underwent a cesarean section for early preeclampsia between June 2014 and March 2024.METHODS Participants were assessed in person during the 32nd week of pregnancy,2 days post-cesarean,and 6 weeks postpartum.According to the Edinburgh Postnatal Depression Scale(EPDS),participants who underwent cesarean section were divided into PPD(n=60)and non-PPD groups(n=227).Furthermore,PPD was diagnosed at 6 weeks postpartum according to depressive symptoms(EPDS score≥11).The demographic and clinical features of PPD were screened.Multivariate logistic regression analysis was used to identify PPD risk factors.RESULTS The prevalence of PPD was 20.9%(60/287)among the 287 women who underwent cesarean section for early-onset preeclampsia.Multivariate logistic regression analyses revealed that advanced age(age>40 years)[odds ratio(OR)=1.93,95%CI:1.31-2.82],previous preeclampsia(OR=7.15,95%CI:5.81-8.85),pre-pregnancy obesity(OR=2.42,95%CI:1.62-3.63),gestational diabetes mellitus(OR=3.52,95%CI:2.51-4.92),preexisting hypertension(OR=1.35,95%CI:1.03-1.89),PPD symptoms(EPDS≥11)at 2 days postpartum(OR=6.15,95%CI:1.32-28.35),high prenatal self-rating anxiety scale score(OR=1.13,95%CI:1.06-1.18),and pain at 6 weeks postpartum(OR=2.16,95%CI:1.28-3.66)were independently associated with PPD.CONCLUSION Risk factors for PPD after cesarean section in women with early-onset preeclampsia include advanced age(age>40 years),pre-pregnancy obesity,previous preeclampsia,gestational diabetes mellitus,preexisting hypertension,PPD symptoms(EPDS≥11)at 2 days postpartum,prenatal anxiety,and pain at 6 weeks postpartum.The early identi-fication of these factors and interventions can mitigate the risk of PPD.
文摘BACKGROUND The incidence of oesophageal adenocarcinoma(OAC)has been reported to be increasing in many countries.Alongside this trend,an increase in incidence of early-onset OAC,defined as OAC in adults aged under 50 years,has been observed.It is unclear whether survival outcomes for early-onset OAC patients differ from older age groups.AIM To investigate survival outcomes in early-onset OAC patients.METHODS Ovid Medline and Embase were searched from inception to January 2022 for relevant studies relating to early-onset OAC and survival outcomes.Results regarding the overall five-year survival and risk of death of younger and older patients with OAC were extracted and pooled using meta-analyses to produce pooled estimates and 95%CIs where possible.RESULTS Eleven studies which compared survival of early-onset OAC,defined as age at diagnosis of<50 years,with older patients were included.A narrative review of median and mean survival demonstrated conflicting results,with studies showing early-onset OAC patients having both better and worse outcomes compared to older age groups.A meta-analysis of five-year survival demonstrated similar outcomes across age groups,with 22%-25%of patients in the young,middle and older age groups alive after five years.A meta-analysis of four studies demon-strated that early-onset OAC patients did not have a significantly increased risk of death compared to middle-aged patients(hazard ratio 1.12,95%CI:0.85-1.47).INTRODUCTION There is concern that the incidence of oesophageal adenocarcinoma(OAC)in patients under 50,described as early-onset OAC,is increasing.However,data regarding survival of younger patients with OAC is sparse.Globally,while increasing age remains a major non-modifiable risk factor for cancer,the incidence of early-onset cancers,largely accepted to be in adults aged under 50 years,is increasing[1].This includes an observed increase in the incidence of gastrointestinal malignancies such as colorectal,oesophageal,gastric and hepatobiliary cancers[2-4].Despite oesophageal squamous cell carcinoma(OSCC)being more common globally(88%of cases)[5],a striking increase in oesophageal OAC incidence has been reported in developed countries,such as the United States and Europe[6,7].Worryingly,the United Kingdom has the highest incidence of OAC cases in the world[8].In addition to the increase in OAC,an increase in incidence of early-onset OAC,defined as OAC in adults aged under 50 years,has been observed[9,10].A population-based cohort in the Netherlands,consisting of 59584 patients,demonstrated the incidence of early-onset OAC to have tripled from 1989 to 2018,while OSCC cases declined in this age group[7].OAC usually develops in the lower third of the oesophagus and the gastro-oesophageal junction,with risk factors including obesity and gastro-oesophageal reflux disease[11].A poor prognosis is observed,with the overall five-year survival rate for oesophageal cancer between 15%-20%,even with treatment[12,13].These low survival rates are likely due to a combination of late diagnosis,intrinsic resistance to systemic therapy and the limited efficacy of surgical resection.Younger patients tend to present at a more advanced stage at diagnosis compared to those diagnosed later in life.A single centre,retrospective study found that 33.3%of patients in the younger age category(<50 years old)presented with stage IV OAC,compared to the 20.6%of the oldest age category(>70 years old)[14].Another population-based study in the Netherlands observed that OAC patients under 50 years old also presented with distant metastasis more often in comparison to older patients(50.5%vs 44.7%),and that tumour differentiation also varied between age groups[15].Reports of survival estimates in patients with early-onset OAC compared with older patients have resulted in contrasting findings to date.Some studies report that due to the advanced stage and aggressiveness of the tumours seen that the prognosis of these patients is almost always worse than their older counterparts[16].In contrast,another study found that the overall survival,as well as stage-specific survival was higher in those who were younger[17].A Dutch study which included only resectable cases found no difference in 5-year disease specific survival[18].Given the conflicting evidence to date,the aim of this systematic review was to investigate survival in OAC patients according to age at diagnosis.A protocol was composed,and the reporting of this systematic review designed,using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines[19].The protocol included:The review question,search strategy,inclusion criteria,type of quality assessment,the strategy for data analysis,and the‘population,intervention,comparator,and outcome’criteria.These are expanded below.
文摘During the last few years,epidemiological data from many countries suggest that the incidence and prevalence of many cancers of the digestive system are shifting from the older to the younger ages,the so-called“early-onset cancer”.This is particularly evident in colorectal cancer and secondarily in other malignant digestive neoplasms,mainly stomach and in a lesser degree pancreas,and biliary tract.It should be emphasized that data concerning digestive neoplasms,except for those referring to the colon and stomach,could be characterized as rather insufficient.The exact magnitude of the shift in younger ages is expected to become clearer shortly,as long as relevant epidemiological data from many parts of the world would be available.The most important question concerns the etiology of this phenomenon,since its magnitude cannot be explained solely by the better diagnostic methodology and the preventive programs applied in many countries.The existing data support the assumption that a number of environ-mental factors may play a primary role in influencing carcinogenesis,sometimes from childhood.Changes that have appeared in the last decades related mainly to eating habits,consistency of gut microbiome and an increase of obese people interacting with genetic factors,ultimately favor the process of carcinogenesis.Even these factors however,are not entirely sufficient to explain the age-related changes in the frequency of digestive neoplasms.Studies of the individual effect of each of the already known factors or factors likely to be involved in the etiology of this phenomenon and studies using state-of-the-art technologies to accurately determine the degree of the population exposure to these factors are required.In this article,we attempt to describe the epidemiological data supporting the age-shifting of digestive malignancies and their possible pathogenesis.Finally,we propose some measures regarding the attitude of the scientific community to this alarming phenomenon.
文摘BACKGROUND The incidence of patients with early-onset pancreatic cancer(EOPC;age≤50 years at diagnosis)is on the rise,placing a heavy burden on individuals,families,and society.The role of combination therapy including surgery,radiotherapy,and chemotherapy in non-metastatic EOPC is not well-defined.AIM To investigate the treatment patterns and survival outcomes in patients with non-metastatic EOPC.METHODS A total of 277 patients with non-metastatic EOPC who were treated at our institution between 2017 and 2021 were investigated retrospectively.Overall survival(OS),disease-free survival,and progression-free survival were estimated using the Kaplan-Meier method.Univariate and multivariate analyses with the Cox proportional hazards model were used to identify prognostic factors.RESULTS With a median follow-up time of 34.6 months,the 1-year,2-year,and 3-year OS rates for the entire cohort were 84.3%,51.5%,and 27.6%,respectively.The median OS of patients with localized disease who received surgery alone and adjuvant therapy(AT)were 21.2 months and 28.8 months,respectively(P=0.007).The median OS of patients with locally advanced disease who received radiotherapy-based combination therapy(RCT),surgery after neoadjuvant therapy(NAT),and chemotherapy were 28.5 months,25.6 months,and 14.0 months,respectively(P=0.002).The median OS after regional recurrence were 16.0 months,13.4 months,and 8.9 months in the RCT,chemotherapy,and supportive therapy groups,respectively(P=0.035).Multivariate analysis demonstrated that carbohydrate antigen 19-9 level,pathological grade,T-stage,N-stage,and resection were independent prognostic factors for non-metastatic EOPC.CONCLUSION AT improves postoperative survival in localized patients.Surgery after NAT and RCT are the preferred therapeutic options for patients with locally advanced EOPC.

文摘BACKGROUND The incidence of early-onset colorectal cancer(EO-CRC)is rising in the United States,and is often diagnosed at advanced stages.Low serum ferritin is often incidentally discovered in young adults,however,the indication for endoscopy in EO-CRC is unclear.AIM To compare serum ferritin between patients with EO-CRC and healthy controls(HCs),and examine the association of serum ferritin in EO-CRC with patient-and disease-specific characteristics.METHODS A retrospective study of patients<50 years with newly-diagnosed EO-CRC was conducted from 1/2013-12/2023.Patients were included if serum ferritin was measured within 2 years prior to 1 year following CRC histologic diagnosis.To supplement the analysis,a cohort of HCs meeting similar inclusion and exclusion criteria were identified for comparison.A sensitivity analysis including only patients with serum ferritin obtained at or before diagnosis was separately performed to minimize risk of confounding.RESULTS Among 85 patients identified with EO-CRC(48 females),the median serum ferritin level was 26 ng/mL(range<1-2759 ng/mL).Compared to HCs(n=80211),there were a higher proportion of individuals with EO-CRC with serum ferritin<20 ng/mL(female 65%,male 40%)versus HCs(female 32.1%,male 7.2%)age 29-39 years(P=0.002 and P<0.00001,respectively).Stage IV disease was associated with significantly higher serum ferritin compared to less advanced stages(P<0.001).Serum ferritin obtained before or at the time of diagnosis was lower than levels obtained after diagnosis.Similar findings were confirmed in the sensitivity analysis.CONCLUSION Severe iron deficiency may indicate an increased risk of EO-CRC,particularly at earlier stages.Further studies defining the optimal serum ferritin threshold and routine incorporation of serum ferritin in screening algorithms is essential to develop more effective screening strategies for EO-CRC.

文摘BACKGROUND Low-molecular-weight heparins(LMWH)are the most commonly used anticoagulants during pregnancy.It is considered to be the drug of choice due to its safety in not crossing placenta.Considering the beneficial effect in the improvement of microcirculation,prophylactic application of LMWH in patients with preeclampsia became a trend.However,the bleeding risk related with LMWH in preeclampsia patients has seldomly been evaluated.This current study aimed to identify the potential risks regarding LMWH application in patients with preeclampsia.CASE SUMMARY Herein we present a case series of three pregnant women diagnosed with preeclampsia on LMWH therapy during pregnancy.All the cases experienced catastrophic hemorrhagic events.After reviewing the twenty-one meta-analyses,the bleeding risk related with LMWH seems ignorable.Only one study analyzed the bleeding risk of LMWH and found a significantly higher risk of developing PPH in women receiving LMWH.Other studies reported minor bleeding risks,none of these were serious enough to stop LMWH treatment.Possibilities of bleeding either from uterus or from intrabdominal organs in preeclampsia patients on LMWH therapy should not be ignored.Intensive management of blood pressure even after delivery and homeostasis suture in surgery are crucial.CONCLUSION Consideration should be given to the balance between benefits and risks of LMWH in patients with preeclampsia.

文摘BACKGROUND Accumulating evidence suggests that the inflammatory cytokine interleukin-6(IL-6)contributes to the pathophysiology of psychiatric disorders.However,there was no study concerning the relationship between IL-6 concentrations and clinical features in the chronic phase of early-onset schizophrenia(EOS).AIM To investigate the relationship between serum IL-6 concentration and the clinical features of EOS.METHODS We measured serum IL-6 Levels from 74 patients with chronic schizophrenia,including 33 with age at onset<21 years(EOS group)and 41 with onset≥21 years in[adult-onset schizophrenia(AOS)group],and from 41 healthy controls.Symptom severities were evaluated using the Positive and Negative Syndrome Scale(PANSS).RESULTS Serum IL-6 concentrations were higher in both EOS and AOS groups than healthy controls(F=22.32,P<0.01),but did not differ significantly between EOS and AOS groups(P>0.05)after controlling for age,body mass index,and other covariates.Negative symptom scores were higher in the EOS group than the AOS group(F=6.199,P=0.015).Serum IL-6 concentrations in the EOS group were negatively correlated with both total PANSS-negative symptom score(r=-0.389,P=0.032)and avolition/asociality subscore(r=-0.387,P=0.026).CONCLUSION Patients with EOS may have more severe negative symptoms than those with adult-onset schizophrenia during the chronic phase of the illness.IL-6 signaling may regulate negative symptoms and its avolition/asociality subsymptoms among the early-onset chronic schizophrenic patients.
文摘Colorectal cancer used to be a common disease among middle-aged and elderly people.In recent years,the incidence of colorectal cancer(Early-onset colorectal cancer,EOCRC)under 50 years old has increased year by year.Different from the traditional late-onset colon cancer(LOCRC),the diagnosis stage of EOCRC is mostly in the late stage,with poor cell differentiation and poor diagnosis,and there is a layer of consensus and guidance on the diagnosis,treatment or screening of EOCRC at presentation.Therefore,fully understanding the disease characteristics and risk exposure factors of EOCRC is helpful to guide early screening and treatment,which ultimately reduces the mortality of EOCRC.In this review article,we summarized the epidemiology,physiology,risk exposure factors and pathological diagnosis of EOCRC,and discussed the diagnosis and treatment prospect of EOCRC.
文摘Objective: To analyze the application effect and value of dydrogesterone in the fertility preservation treatment of preeclampsia. Methods: Forty cases of patients with preeclampsia admitted to our hospital between January 2023 and January 2024 were divided randomly into a control group and an observation group of 20 cases each. The control group applied progesterone to preserve the fetus, and the observation group applied dydrogesterone. The symptom relief time, hormone levels before and after treatment, as well as adverse drug reactions, and the effect of fetal preservation between the two groups were compared. Results: The time to relieve vaginal bleeding, abdominal pain. and lumbago in the observation group was shorter than that in the control group (P < 0.05). After treatment, the progesterone levels and incidence of adverse drug reactions in the observation group were lower than those in the control group (P < 0.05). The success rate of fertility preservation in the observation group was higher than that in the control group (P < 0.05). Conclusion: In the treatment of fetal preservation of preeclampsia, the application of dydrogesterone positively alleviated vaginal bleeding, abdominal pain, and lumbago, with mild adverse reactions and a good effect on fetal preservation.
文摘Background: Preeclampsia (PE) is one of the forms of hypertensive diseases that occur during pregnancy. Early-onset preeclampsia (EOP), which occurred before 34 weeks, proved to be the deadliest. Indeed, it is characterized by a poor maternal and fetal prognosis. EOP has a disparate incidence in the world varying between 0.9% and 31%. Several risks factors are associated with the occurrence of EOP, which is responsible of several adverse obstetrical outcomes. Complications can affect up to 85% of pregnant women with EOP, especially when EOP appears very early, before 28 or even 25 weeks’ gestation. Objectives: To determine frequency of EOP at the University Clinics of Kinshasa, to describe sociodemographic and clinical characteristics of pregnant women with EOP and to identify its risks factors and its association adverse obstetrical outcomes. Methods: The study will be a cross-sectional analytical study in University Clinics of Kinshasa from January 2016 to December 2022. The minimal size will be 119. Our study population will consist of pregnant women who consult for antenatal best care and are neonates in our Clinic. Result will be presented as percentage proportion. Comparison and proportion means between groups will be made using Student’s test and Pearson’s chi-square test, respectively. Our test will be statistically significant for a p-value ≤ than less 0.05. Data will be collected and analysed anonymously and confidentiality. Conclusion: We believe that our study should enable us to identify profile of gestational carriers at risk of EOP in our environment, as well as prognosis associated with this entity, with a view to arousing particular interest in EOP.
文摘Colorectal cancer(CRC)is one of the most prevalent malignancies worldwide.Although most prevalent among older people,its incidence above 50 years old has been decreasing globally in the last decades,probably as a result of better screening.Paradoxically,its incidence in patients below 50 years old[early-onset CRC(EO-CRC)]has been increasing,for reasons not yet fully understood.EOCRC’s increasing incidence is genre independent but shows racial disparities and has been described to occur worldwide.It follows a birth-cohort effect which probably reflects a change in exposure to CRC risk factors.Its incidence is predicted to double until 2030,which makes EO-CRC a serious public health issue.Both modifiable and non-modifiable risk factors have been identified-some are potential targets for preventive measures.EO-CRC is often diagnosed at advanced stages and histological features associated with poor prognosis have been described.EO-CRC presents some distinctive features:Microsatellite instability is common,but another subtype of tumours,both microsatellite and chromosome stable also seems relevant.There are no age-specific treatment protocols and studies on EO-CRC survival rates have shown conflicting data.Due to the higher germline pathological mutations found in EO-CRC patients,an accurate genetic risk evaluation should be performed.In this review,we summarize the current evidence on epidemiological,clinical,histopathological and molecular features of EO-CRC and discuss the contribution of genetics and lifestyle risk factors.We further comment on screening strategies and specific dimensions to consider when dealing with a younger cancer patient.
文摘Early-onset colorectal cancer(EOCRC)has been rising in global prevalence and incidence over the past several decades.Environmental influences,including generational lifestyle changes and rising obesity,contribute to these increased rates.While the rise in EOCRC is best documented in western countries,it is seen throughout the world,although EOCRC may have distinct genetic mutations in patients of different ethnic backgrounds.Pathological and molecular characterizations show that EOCRC has a distinct presentation compared with later-onset colorectal cancer(LOCRC).Recent studies have identified DNA,RNA,and protein-level alterations unique to EOCRC,revealing much-needed biomarkers and potential novel therapeutic targets.Many molecular EOCRC studies have been performed with Caucasian and Asian EOCRC cohorts,however,studies of other ethnic backgrounds are limited.In addition,certain molecular characterizations that have been conducted for LOCRC have not yet been repeated in EOCRC,including high-throughput analyses of histone modifications,mRNA splicing,and proteomics on large cohorts.We propose that the complex relationship between cancer and aging should be considered when studying the molecular underpinnings of EOCRC.In this review,we summarize current EOCRC literature,focusing on sporadic molecular alterations in tumors,and their clinical implications.We conclude by discussing current challenges and future directions of EOCRC research efforts.
文摘BACKGROUND Colon cancer(CC)is one of the most common cancers of the digestive tract,the third most common cancer worldwide,and the second most common cause of cancer-related deaths.Previous studies have demonstrated a higher risk of lymph node metastasis(LNM)in young patients with CC.It might be reasonable to treat patients with early-onset locally advanced CC with extended lymph node dissection.However,few studies have focused on early-onset CC(ECC)patients with LNM.At present,the methods of predicting and evaluating the prognosis of ECC patients with LNM are controversial.From the data of patients with CC obtained from the Surveillance,Epidemiology,and End Results(SEER)database,data of young patients with ECC(≤50 years old)was screened.Patients with unknown data were excluded from the study,while the remaining patients were included.The patients were randomly divided into a training group(train)and a testing group(test)in the ratio of 7:3,while building the model.The model was constructed by the training group and verified by the testing group.Using multiple Cox regression models to compare the prediction efficiency of LNM indicators,nomograms were built based on the best model selected for overall survival(OS)and cause-specific survival(CSS).In the two groups,the performance of the nomogram was evaluated by constructing a calibration plot,time-dependent area under the curve(AUC),and decision curve analysis.Finally,the patients were grouped based on the risk score predicted by the prognosis model,and the survival curve was constructed after comparing the survival status of the high and low-risk groups.RESULTS Records of 26922 ECC patients were screened from the SEER database.N classification,positive lymph nodes(PLN),lymph node ratio(LNR)and log odds of PLN(LODDS)were considered to be independent predictors of OS and CSS.In addition,independent risk factors for OS included gender,race,marital status,primary site,histology,grade,T,and M classification,while the independent prognostic factors for CSS included race,marital status,primary site,grade,T,and M classification.The prediction model including LODDS is composed of minimal Akaike information criterion,maximal concordance indexes,and AUCs.Factors including gender,race,marital status,primary site,histology,grade,T,M classification,and LODDS were integrated into the OS nomogram,while race,marital status,primary site,grade,T,M classification,and LODDS were included into the CSS nomogram.The nomogram representing both cohorts had been successfully verified in terms of prediction accuracy and clinical practicability.CONCLUSION LODDS is superior to N-stage,PLN,and LNR of ECC.The nomogram containing LODDS might be helpful in tumor evaluation and clinical decision-making,since it provides an appropriate prediction of ECC.
文摘Introduction: Preeclampsia can lead to several maternal and perinatal adverse effects. There are few published data on the association between transmembrane serine protease 6 (TMPRSS6) gene polymorphism and preeclampsia. Objective: To assess the association between TMPRSS6 gene polymorphism rs855791SNP in women with preeclampsia compared with healthy pregnant women. Method: A case-control study (60 women in each arm) was conducted at Saad Abuaela Maternity Hospital in Khartoum, Sudan. Sociodemographic and clinical data were gathered through a questionnaire. The participant was genotype for TMPRSS6 gene rs855791SNP using Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP). The results were confirmed by DNA sequencing. Result: There was no significant difference in the median of age, parity, and body mass index. The distribution of the genotypes and alleles of TMPRSS6 rs855791 was consistent with the HWE. The overall TMPRSS6 rs855791 polymorphism was not significantly associated with preeclampsia. However, the proportion of heterozygotes (TC) was considerably higher in the women with preeclampsia (46.7%) than in the control group (23.3%) (p = 0.001;OR = 2.71;95% CI = 1.21 - 6.07). The proportion of homozygotes (TT) and T alleles was not significantly different between women with preeclampsia and the control group.

文摘BACKGROUND Preeclampsia(PE)is a multisystemic metabolic disease with an undetermined etiology.PE is a worldwide cause of maternal and perinatal morbidity,subdivided into early(EoPE)and late-onset(LoPE)according to 34 wk of gestation as a divider.Many researchers investigated biomarkers for predicting PE to halt its consequences on the feto-maternal outcome.Elabela(Ela)is a newly discovered peptide hormone that was implicated in PE pathogenesis.Earlier rodent studies discussed Ela’s role in controlling blood pressure.Moreover,Ela deficiency was associated with PE development.AIM To test whether plasma Ela could serve as a reliable marker for predicting PE based on the time of onset(EoPE vs LoPE)compared to age and body mass matched healthy controls since no definitive treatment exists for PE but to terminate a pregnancy.METHODS This case-control study recruited(n=90)pregnant who fulfilled inclusion criteria;they were allocated into three groups:EoPE(30/90)(<34 wk of gestation);LoPE(30/90)(≥34 wk of gestation);and healthy pregnant(30/90).Demographic criteria;biochemical,hematological,and maternal plasma Ela levels were recorded for comparison.RESULTS Serum Ela was significantly reduced in EoPE compared to LoPE and healthy controls(P=0.0023).The correlation confirmed a strong inverse relationship with mean atrial blood pressure(r=-0.7,P<0.001),while gestational age and platelets count showed a moderate correlation with(r=0.4 with P<0.0001).No correlation was confirmed between the body mass index(BMI)and urine albumin.The predictive ability of 25 centile serum Ela had an Odds ratio of 5.21,95%confidence interval(1.28,21.24),P=0.02 for predicting EoPE.The receiver operator characteristic curve defined the Ela cutoff value at>9.156 with 96.7%and 93.3%sensitivity and specificity,P<0.0001 in predicting EoPE.CONCLUSION A strong correlation of serum Ela with PE parameters with excellent sensitivity and specificity in distinguishing EoPE independent of the BMI,age,and blood pressure which makes Ela a recommendable marker in screening.Further research is warranted to explore prognostic and therapeutic applications for Ela in PE.
文摘Background: FoxP3 gene variants have been linked to endometriosis, infertility, and autoimmune illnesses, according to numerous researches. Maternal sensitivity to the PE gene and the genetic variations of FoxP3 has not been thoroughly investigated. Objective: Investigation of the immune-histochemical expression of FoxP3 in placental tissue of PE patients. Methods: A total of 26 pre-eclamptic women as a case and 26 ethnically matched healthy pregnant women as a control group aged between 18 and 40 years old of different gravidity and parity referred to the labor ward for delivery either by vaginal delivery or cesarean section was enrolled to investigate the immunohistochemical expression of FOXP3 in placental tissue of PE patients. Results: Lower expression of FOXP3 IHC was statistically significant and noted in the group of preeclampsia compared to the healthy control group. Lower gestational age at delivery and a higher percentage of cesarean section were statistically significant and noted in the group of preeclampsia compared to the healthy control group. Conclusion: In comparison to the healthy control group, preeclampsia patients had statistically significantly lower FOXP3 IHC expression, and FOXP3 polymorphism was associated with the development of PE. Our findings can serve as a guide for statistical analyses and functional investigations that are more in-depth.

文摘Background:Preeclampsia(PE),characterized by hypertension and proteinuria,leads to serious maternal and infant complications.Uridine-cytidine kinase 2(UCK2)belongs to the UCK family,a class of enzymes that catalyzes the conversion of uridine and cytidine to monophosphate form.However,the role of UCK2 in PE has not been reported.Methods:The expression of UCK2 was detected in the placenta of PE patients and N(ω)-nitro-L-arginine methyl esterinduced PE mouse model.Through forced up-regulation or down-regulation of UCK2 in vitro,we examined the effects of UCK2 on the proliferation,apoptosis,migration,and invasion of trophoblast cells.Stattic,the inhibitor of STAT3 pathway,was used to investigate whether the STAT3 pathway mediates the biological function of UCK2 in trophoblast cells.Results:The present study found that UCK2 showed low expression in the placenta of PE patients and PE mouse model.MTT(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)and flow cytometry assays verified that up-regulation of UCK2 promoted the proliferation of trophoblast cells,while the silence of UCK2 suppressed cell proliferation.Besides,flow cytometry and TdT-mediated dUTP Nick-End Labeling assays demonstrated that knockdown of UCK2 resulted in apoptosis of trophoblast cells.The wound healing and transwell assays showed that the migration and invasion activities of the trophoblast cells were facilitated by the overexpression of UCK2 and were blocked by the silence of UCK2.Furthermore,the expression of phosphorylated STAT3 was increased with the upregulation of UCK2 and decreased with the inhibition of UCK2.When the STAT3 pathway was blocked by its inhibitor stattic,the promotion effects of UCK2 on trophoblast cells were suppressed.Conclusion:UCK2 promotes the proliferation,migration,and invasion of trophoblast cells,and these effects may be partly mediated by the activation of the STAT3 pathway.
文摘Background: Knowledge of temporal evolution of preeclampsia (PE) in its various aspects is essential in strategies to reduce maternal and perinatal morbidity and mortality. Preeclampsia is a public health problem due to maternal mortality associated with it worldwide (5.6%). Improving quality of its management is a major challenge in low-income countries where, despite progress made in this field, PE remains a major factor in maternal morbidity and mortality. Objective: To evaluate temporal evolution of frequency, risk factors and complications of PE at the University clinics of Kinshasa (UCK). Methods: Descriptive and cross-sectional study concerning minimum simple size of 119 pregnant women who consulted for antenatal care at the University clinics of Kinshasa from January 2012 to December 2022. Results will be reported as percentage proportion, mean and standard deviation. Comparison of proportion and means between groups will be made using Student’s t-test and Pearson’s chi-square test, respectively. The test will be statistically significant for a p value ≤ less than 0.05. Data will be collected and analysed anonymously and confidentially. Conclusion: This study will allow us to evaluate the effectiveness of different prevention and treatment modalities used over time in management of preeclampsia in our setting.
文摘Objective:In determining the effects of yoga practice on mild preeclampsia,this study examines the blood pressure,blood platelet(PLT)count,and proteinuria status in pregnant women over 20 weeks of pregnancy.Materials and Methods:This research is an experimental study with a pre–post intervention design.We collected forty pregnant women with mild preeclampsia from all populations.All participants agreed to practice 30 min of yoga every week for 1 month.The blood pressure,the blood PLT count,and proteinuria were measured before and after the yoga intervention.The statistical analysis used the t‑test for the blood PLT count variable,the McNemar test for the proteinuria variable,and the Wilcoxon test for the blood pressure variable.Results:The results showed a decrease in systole blood pressure from 134.17±7.17 mmHg before a yoga intervention to 120±4.17 mmHg after yoga intervention(P<0.001)and a decrease in diastole blood pressure from 89.58±5.5 mmHg before the intervention to 79.38±4.25 mmHg after the intervention(P<0.001).However,there was no significant difference in blood PLT count(P=0.104)and proteinuria(P=0.063)before and after a yoga intervention in pregnant women with mild preeclampsia patients.Conclusions:Yoga exercise during pregnancy(upper 20 weeks of gestation)significantly decreased systolic and diastolic blood pressure in mild preeclampsia patients.
文摘In tropical countries, malaria and preeclampsia/eclampsia are common diseases of pregnancy;and placenta have been implicated in the pathophysiology of both disease processes. The two diseases have pathophysiologic similarities in the placenta such as placenta ischaemia, endothelial dysfunction and production of pro-inflammatory cytokine. Yet, there is paucity of studies on the association of these two disease processes. Determining the association between the two disease processes may help to unravel the pathogenesis of preeclampsia and also help in its prevention and patient management. Objective: Determined the association between placenta malaria parasitemia and preeclampsia/eclampsia among parturients at Alex Ekwueme Federal University Teaching Hospital Abakaliki. Materials and Methods: This was a case control study that was conducted in the Labour wards of department of Obstetrics and Gynaecology, Alex Ekwueme Federal University Teaching Hospital Abakaliki (AEFUTHA) and Mile 4 Missionary Hospital Abakaliki, a comprehensive health care centre in Abakaliki, Ebonyi state. It was conducted over a period of 6 months between 1<sup>st</sup> October 2021 and 31<sup>st</sup> March, 2022. The cases in this study were parturients that developed preeclampsia/eclampsia in the course of pregnancy, while the controls were parturient without preeclampsia/eclampsia. Interviewer-administered questionnaires were used to collect data on socio-demographic characteristics, obstetrics and medical histories. Histological examinations were conducted to isolate plasmodium falciparum parasites from placenta samples obtained from the maternal surface of the placenta. The data was processed using Epi Info software. Categorical variables were analyzed using Mc Nemar X<sup>2</sup> test, with a p-value of 0.05 considered statistically significant. Logistic regression models were used to estimate the odds ratios (OR) and 95% CI of the association between placenta malaria parasites and preeclampsia/eclampsia was conducted. Relative risk with 95% CI was used to determine both fetal and maternal outcomes. Results: The prevalence of preeclampsia during the study period was 2.9%. Placenta malaria was positive in twenty one (21) of the 67 cases of preeclampsia/eclampsia analyzed, giving a prevalence of 31.3% and in eleven (11) out of 68 controls (normotensive) patients analyzed, giving a prevalence of 16.2%. The presence of placenta malaria significantly increased the odds of developing preeclampsia/eclampsia among parturients (OR = 2.4, 95% CI = 1.0 - 5.4, P value = 0.04). Presence of placenta malaria in mothers with preeclampsia/eclampsia was associated with adverse pregnancy outcomes such as cerebrovascular accident (RR = 19.2, 95% CI = 1.1 - 341.7, P value = 0.04), DIC (RR = 10.9, 95% CI = 1.4 - 88.0, P value = 0.02), abruptio placenta (RR = 2.4, 95% CI = 1.2 - 4.8, P value = 0.01), pulmonary edema (RR = 2.7, 95% CI = 1.1 - 25.9, P value = 0.03), IUGR (RR = 2.1, 95% CI = 1.1 - 4.5, P value = 0.03) and IUFD (RR = 3.8, 95% CI = 1.3 - 11.7, P value = 0.02). Presence of placenta malaria also increased the risk of NICU admission (RR = 2.6, 95% CI = 1.1 - 6.0, P value = 0.03), Low 1<sup>st</sup> minute APGAR score (RR = 2.7, 95% CI = 1.2 - 6.1, P value = 0.02) and Low 5<sup>th</sup> minute APGAR score (RR = 3.0, 95% CI = 1.0 - 8.6, P value = 0.04) among neonates delivered by mothers with preeclampsia/eclampsia. However, presence of placenta malaria did not significantly increase maternal and perinatal mortalities. Conclusion: There is a higher prevalence of placenta malaria among mothers with preeclampsia/eclampsia when compared with normotensive controls and this was associated with increased risk of certain maternal and perinatal morbidities. Placental malaria was not associated with increased risk of either maternal or perinatal mortality.
