SEARCH STRATEGY: A computer-based, online, literature search of PubMed (1966/2007), China Biological Medicine Database (CBM-disc, 1979/2007) and CNKI (www.cnki.net, 1979/2007) was performed to screen for related studies. DATA SELECTION: Cohort or case-controlled studies that focused on risk factors of progressive ischemic stroke were selected for review. Two reviewers independently extracted data and assessed study quality according to Cochrane Collaboration guidelines. Statistical analysis was performed using RevMan software. MAIN OUTCOME MEASUREMENT: Risk factors for progressive ischemic stroke. RESULTS: Using the inclusion criteria, 29/781 studies published in English and Chinese were initially reviewed, including 19 cohort studies and 10 case-control studies. Despite variations in determination of progressive ischemic stroke and the intervals between 2 evaluations, all studies described the diagnostic criteria for progressive ischemic stroke. Logistic analysis was employed in 20 of the studies. Meta-analysis of primary data in the related studies determined that the following factors that significantly correlated with progressive ischemic stroke: fever [risk ratio (RR) = 2.26, 95% confidence interval (CO: 1.20-4.26, P = 0.01; odds ratio (OR) = 2.85, 95% CI: 1.64-4.98, P 〈 0.01 )]; diabetes (RR = 1.38, 95% CI: 1.18-1.61, P 〈 0.01 ; OR = 2.48, 95% Ch 1.93-3.19, P 〈 0.01 ); coronary heart disease (RR = 1.22, 95% CI: 1.08-1.38, P 〈 0.01); neuroimaging transformation (RR= 1.55, 95%CI: 1.34-1.80, P〈 0.01; OR= 2.29, 95% CI: 1.47-3.58, P〈 0.01); and hyperglycemia (RR = 2.62, 95% CI: 1.86-3.68, P 〈 0.01 ; OR = 3.49, 95% CI: 1.92-6.35, P 〈 0.01). CONCLUSION: Fever, diabetes, coronary heart disease, neuroimaging transformation, and hyperglycemia are important risk factors for progressive ischemic stroke.

Therefore, it would be important toknow which risk factors may favour the appearance of antenatal depression inorder to carry out appropriate prevention interventions. The aim of the presentreview was to identify the main risk factors of antenatal depression. We searchedin databases PubMed and PsycINFO for articles published about the factorsassociated with antenatal depression from January 2010 through December 2020.The literature review identified three main groups of antenatal depression riskfactors: sociodemographic, obstetric, and psychological. First, among thesociodemographic variables, the low level of studies and the economic incomeclearly stood out from the rest. Then, not having planned the pregnancy was themain obstetric variable, and finally, the main psychological risk factors werehaving a history of psychological disorders and/or depression as well aspresenting anxiety, stress, and/or low social support during pregnancy. Thisreview shows that the antenatal depression is affected by multiple factors. Mostcan be identified at the beginning of the pregnancy, and some are risk factorspotentially modifiable through appropriate interventions, such as psychologicalfactors. For this reason, it is important to carry out a good screening for depressionduring pregnancy and consequently, be able to prevent its appearance ortreat it if necessary.展开更多

MSkIs affect members of the military during initial training,operational training, and deployment and have a direct negative impact on overall troop readiness. Currently, a systematic overview of all risk factors for MSkIs in the military is not available.Methods: A systematic literature search was carried out using the PubMed, Ovid/Medline, and Web of Science databases from January 1, 2000 to September 10, 2019. Additionally, a reference list scan was performed(using the “snowball method”). Thereafter, an international, multidisciplinary expert panel scored the level of evidence per risk factor, and a classification of modifiable/non-modifiable was made.Results: In total, 176 original papers and 3 meta-analyses were included in the review. A list of 57 reported potential risk factors was formed. For 21 risk factors, the level of evidence was considered moderate or strong. Based on this literature review and an in-depth analysis, the expert panel developed a model to display the most relevant risk factors identified, introducing the idea of the “order of importance” and including concepts that are modifiable/nonmodifiable, as well as extrinsic/intrinsic risk factors.Conclusions: This is the qualitative systematic review of studies on risk factors for MSkIs in the military that has attempted to be all-inclusive. A total of 57 different potential risk factors were identified, and a new, prioritizing injury model was developed. This model may help us to understand risk factors that can be addressed, and in which order they should be prioritized when planning intervention strategies within military groups.展开更多

文摘BACKGROUND Colorectal signet-ring cell carcinoma(CSRCC)is a rare clinical entity which accounts for approximately 1%of all colorectal cancers.Although multiple studies concerning this specific topic have been published in the past decades,the pathogenesis,associated risk factors,and potential implications on treatment are still poorly understood.Besides the low incidence,historically confusing histological criteria have resulted in confusing data.Nevertheless,the rising incidence of CSRCC along with relatively young age at presentation and associated dismal prognosis,highlight the actual interest to synthesize the known literature regarding CSRCC.AIM To provide an updated overview of risk factors,prognosis,and management of CSRCC.METHODS A literature search in the MEDLINE/PubMed database was conducted with the following search terms used:‘Signet ring cell carcinoma’and‘colorectal’.Studies in English language,published after January 1980,were included.Studies included in the qualitative synthesis were evaluated for content concerning epidemiology,risk factors,and clinical,diagnostic,histological,and molecular features,as well as metastatic pattern and therapeutic management.If possible,presented data was extracted in order to present a more detailed overview of the literature.RESULTS In total,67 articles were included for qualitative analysis,of which 54 were eligible for detailed data extraction.CSRCC has a reported incidence between 0.1%-2.4%and frequently presents with advanced disease stage at the time of diagnosis.CSRCC is associated with an impaired overall survival(5-year OS:0%-46%)and a worse stagecorrected outcome compared to mucinous and not otherwise specified adenocarcinoma.The systematic use of exploratory laparoscopy to determine the presence of peritoneal metastases has been advised.Surgery is the mainstay of treatment,although the rates of curative resection in CSRCC(21%-82%)are lower compared to those in other histological types.In case of peritoneal metastasis,cytoreductive surgery with hyperthermic intraperitoneal chemotherapy should only be proposed in selected patients.CONCLUSION CSRCC is a rare clinical entity most often characterized by young age and advanced disease at presentation.As such,diagnostic modalities and therapeutic approach should be tailored accordingly.

文摘OBJECTIVE: To determine the risk factors for progressive ischemic stroke, and to prevent onset and make a prognosis of disease, the present study systemically evaluated 19 cohort studies and 10 case-controlled studies of progressive ischemic stroke. SEARCH STRATEGY: A computer-based, online, literature search of PubMed (1966/2007), China Biological Medicine Database (CBM-disc, 1979/2007) and CNKI (www.cnki.net, 1979/2007) was performed to screen for related studies. DATA SELECTION: Cohort or case-controlled studies that focused on risk factors of progressive ischemic stroke were selected for review. Two reviewers independently extracted data and assessed study quality according to Cochrane Collaboration guidelines. Statistical analysis was performed using RevMan software. MAIN OUTCOME MEASUREMENT: Risk factors for progressive ischemic stroke. RESULTS: Using the inclusion criteria, 29/781 studies published in English and Chinese were initially reviewed, including 19 cohort studies and 10 case-control studies. Despite variations in determination of progressive ischemic stroke and the intervals between 2 evaluations, all studies described the diagnostic criteria for progressive ischemic stroke. Logistic analysis was employed in 20 of the studies. Meta-analysis of primary data in the related studies determined that the following factors that significantly correlated with progressive ischemic stroke: fever [risk ratio (RR) = 2.26, 95% confidence interval (CO: 1.20-4.26, P = 0.01; odds ratio (OR) = 2.85, 95% CI: 1.64-4.98, P 〈 0.01 )]; diabetes (RR = 1.38, 95% CI: 1.18-1.61, P 〈 0.01 ; OR = 2.48, 95% Ch 1.93-3.19, P 〈 0.01 ); coronary heart disease (RR = 1.22, 95% CI: 1.08-1.38, P 〈 0.01); neuroimaging transformation (RR= 1.55, 95%CI: 1.34-1.80, P〈 0.01; OR= 2.29, 95% CI: 1.47-3.58, P〈 0.01); and hyperglycemia (RR = 2.62, 95% CI: 1.86-3.68, P 〈 0.01 ; OR = 3.49, 95% CI: 1.92-6.35, P 〈 0.01). CONCLUSION: Fever, diabetes, coronary heart disease, neuroimaging transformation, and hyperglycemia are important risk factors for progressive ischemic stroke. Interventions for these risk factors could effectively prevent occurrence of progressive ischemic stroke.
文摘BACKGROUND Lymph node metastasis(LNM)affects the application and outcomes of endoscopic resection in T1 esophageal squamous cell carcinoma(ESCC).However,reports of the risk factors for LNM have been controversial.AIM To evaluate risk factors for LNM in T1 ESCC.METHODS We searched Embase,PubMed and Cochrane Library to select studies related to LNM in patients with T1 ESCC.Included studies were divided into LNM and non-LNM groups.We performed a meta-analysis to examine the relationship between LNM and clinicopathologic features.Odds ratio(OR),mean differences and 95%confidence interval(CI)were assessed using a fixed-effects or randomeffects model.RESULTS Seventeen studies involving a total of 3775 patients with T1 ESCC met the inclusion criteria.After excluding studies with heterogeneity based on influence analysis,tumor size(OR=1.93,95%CI=1.49-2.50,P<0.001),tumor location(OR=1.46,95%CI=1.17-1.82,P<0.001),macroscopic type(OR=3.17,95%CI=2.33-4.31,P<0.001),T1 substage(OR=6.28,95%CI=4.93-8.00,P<0.001),differentiation(OR=2.11,95%CI=1.64-2.72,P<0.001)and lymphovascular invasion(OR=5.86,95%CI=4.60-7.48,P<0.001)were found to be significantly associated with LNM.Conversely,sex,age and infiltrative growth pattern were not identified as risk factors for LNM.CONCLUSION A tumor size>2 cm,lower location,nonflat macroscopic type,T1b stage,poor differentiation and lymphovascular invasion were associated with LNM in patients with T1 ESCC.
文摘Depression is the most prevalent mental disorder in pregnancy, and yet it is lessstudied than postpartum depression despite the consequences it may have onboth the pregnant woman and her offspring. Therefore, it would be important toknow which risk factors may favour the appearance of antenatal depression inorder to carry out appropriate prevention interventions. The aim of the presentreview was to identify the main risk factors of antenatal depression. We searchedin databases PubMed and PsycINFO for articles published about the factorsassociated with antenatal depression from January 2010 through December 2020.The literature review identified three main groups of antenatal depression riskfactors: sociodemographic, obstetric, and psychological. First, among thesociodemographic variables, the low level of studies and the economic incomeclearly stood out from the rest. Then, not having planned the pregnancy was themain obstetric variable, and finally, the main psychological risk factors werehaving a history of psychological disorders and/or depression as well aspresenting anxiety, stress, and/or low social support during pregnancy. Thisreview shows that the antenatal depression is affected by multiple factors. Mostcan be identified at the beginning of the pregnancy, and some are risk factorspotentially modifiable through appropriate interventions, such as psychologicalfactors. For this reason, it is important to carry out a good screening for depressionduring pregnancy and consequently, be able to prevent its appearance ortreat it if necessary.

文摘Objectives:This review aimed to explore the independent risk factors of postpartum urinary retention(PUR)after a vaginal delivery.Methods:The Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)was followed and relevant studies were retrieved from eleven databases.The quality of the included articles was assessed using Critical Appraisal Skills Programme tools or the Appraisal tool for Cross-Sectional Studies.The data analysis was performed using Review Manager version 5.3.Results:A total of nine articles were included and five risk factors were identified,namely,episiotomy(OR=2.99,95%CI=1.31e6.79,P=0.009),epidural analgesia(OR=2.48,95%CI=1.09e5.68,P=0.03),primiparity(OR=2.17,95%CI=1.06e4.46,P=0.03),instrumental delivery(OR=4.01,95%CI=1.97 e8.18,P<0.001),and the duration of the second stage of labor(MD=15.24,95%CI=11.20e19.28,P<0.001).However,fetal birth weights of more than 3800 g were not identified as an independent risk factor(MD=64.41,95%CI=-12.59 to 141.41,P=0.10).Conclusion:This systematic review indicated that the independent risk factors for PUR were found to include episiotomy,epidural analgesia,instrumental delivery,primiparity,and a longer second stage of labor.In clinical practice,healthcare providers could pay more attention to women with these factors and prevent postpartum urinary retention.
文摘Background: Musculoskeletal injuries(MSkIs) are a leading cause of health care utilization, as well as limited duty and disability in the US military and other armed forces. MSkIs affect members of the military during initial training,operational training, and deployment and have a direct negative impact on overall troop readiness. Currently, a systematic overview of all risk factors for MSkIs in the military is not available.Methods: A systematic literature search was carried out using the PubMed, Ovid/Medline, and Web of Science databases from January 1, 2000 to September 10, 2019. Additionally, a reference list scan was performed(using the “snowball method”). Thereafter, an international, multidisciplinary expert panel scored the level of evidence per risk factor, and a classification of modifiable/non-modifiable was made.Results: In total, 176 original papers and 3 meta-analyses were included in the review. A list of 57 reported potential risk factors was formed. For 21 risk factors, the level of evidence was considered moderate or strong. Based on this literature review and an in-depth analysis, the expert panel developed a model to display the most relevant risk factors identified, introducing the idea of the “order of importance” and including concepts that are modifiable/nonmodifiable, as well as extrinsic/intrinsic risk factors.Conclusions: This is the qualitative systematic review of studies on risk factors for MSkIs in the military that has attempted to be all-inclusive. A total of 57 different potential risk factors were identified, and a new, prioritizing injury model was developed. This model may help us to understand risk factors that can be addressed, and in which order they should be prioritized when planning intervention strategies within military groups.
文摘Coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2 has become a pandemic disease.It also increases the risk of co-infections.Mucormycosis is a severe fungal infectious disease and its causative agent,mucormycetes,belongs to an opportunist fungus Mucoraceae family.Mucormycosis in COVID-19 patients with mucormycosis presents an additional challenge worldwide.Mucormycosis shares certain risk factors and signs and symptoms with COVID-19.In this review,we summarize manifestations and risk factors of mucormycosis and COVID-19.
文摘BACKGROUND Patients with a history of primary brain tumors can be eligible for organ donation under extended criteria.The risk assessment of tumor transmission via organ transplant in primary brain tumors is primarily based on the assessment of tumor histotype and grade.Previous surgeries,chemo-/radiotherapy,and ventriculoperitoneal shunt placement can lead to a disruption of the blood-brain barrier,concurring to an increase in the transmission risk.AIM To investigate the role of tumor transmission risk factors in donors with oligodendrogliomas and astrocytomas.METHODS We searched PubMed and EMBASE databases for studies reporting extraneural spreading of oligoden-drogliomas and astrocytomas and extracted clinical-pathological data on the primary tumor histotype and grade,the elapsed time from the diagnosis to the onset of metastases,sites and number of metastases,prior surgeries,prior radiotherapy and/or chemotherapy,ventriculoatrial or ventriculo-peritoneal shunt placement,and the presence of isocitrate dehydrogenase 1/2 mutation and 1p/19q codeletion.Statistical analysis was performed using R software.Statistical correlation between chemotherapy or radiotherapy and the presence of multiple extra-central nervous system metastases was analyzed usingχ2 and Fischer exact test.The Kaplan-Meier method was used to evaluate the presence of a correlation between the metastasis-free time and:(1)Localization of metastases;(2)The occurrence of intracranial recurrences;and(3)The occurrence of multiple metastases.RESULTS Data on a total of 157 patients were retrieved.The time from the initial diagnosis to metastatic spread ranged from 0 to 325 mo in patients with oligodendrogliomas and 0 to 267 mo in those with astrocytomas.Respectively,19%and 39%of patients with oligodendroglioma and astrocytoma did not receive any adjuvant therapy.The most frequent metastatic sites were bone,bone marrow,and lymph nodes.The lungs and the liver were the most commonly involved visceral sites.There was no significant correlation between the occurrence of multiple metastases and the administration of adjuvant chemo-/radiotherapy.Patients who developed intracranial recurrences/metastases had a significantly longer extraneural metastasis-free time compared to those who developed extraneural metastases in the absence of any intra-central nervous system spread.CONCLUSION A long follow-up time does not exclude the presence of extraneural metastases.Therefore,targeted imaging of bones and cervical lymph nodes may improve safety in the management of these donors.
