Article Synopsis
  • The study reviews the impact of vitamin D deficiency during different stages of pregnancy on the risk of preterm birth (PTB), analyzing 24 observational studies.
  • Results indicate that vitamin D deficiency in the first and third trimesters does not significantly increase the risk of PTB, while deficiency in the second trimester may elevate the risk, as indicated by a subgroup analysis.
  • The findings suggest that further monitoring of vitamin D levels, especially during the second trimester, could be beneficial for expecting mothers to mitigate potential risks associated with PTB.

Minimally invasive surgery includes traditional laparoscopic and robot-assisted surgery. Although many studies related to robotic surgery and laparoscopic surgery have been published, when doing our search, scientometric studies that focus on related robotic surgery versus laparoscopic surgery were limited. In this study, we aimed to analyze and review the research hots and research status of robotic surgery versus laparoscopic surgery.

Several studies have indicated that stroke survivors with multiple lesions or with larger lesion volumes have a higher risk of stroke recurrence. However, the relationship between lesion locations and stroke recurrence is unclear. We conducted a prospective cohort study of first-ever ischemic stroke survivors who were consecutively enrolled from January 2010 to December 2015.

Background: Despite the fact that thyroid surgery has evolved towards minimal incisions and endoscopic approaches, the role of total endoscopic thyroidectomy (TET) in thyroid cancer has been highly disputed. We performed a systematic review and meta-analyses of peer reviewed studies in order to evaluate the safety and effectiveness of TET compared with conventional open thyroidectomy (COT) in papillary thyroid cancer (PTC).

Method: Medical literature databases such as PubMed, Embase, the Cochrane Library, and Web of science were systematically searched for articles that compared TET and COT in PTC treatment from database inception until March 2019.

Objective: To evaluate the diagnostic accuracy of transthoracic echocardiography (TTE) in patients with pulmonary hypertension (PH).

Design: Systematic review and meta-analysis.

Data Sources And Eligibility Criteria: Embase, Cochrane Library for clinical trials, PubMed and Web of Science were used to search studies from inception to 19 June, 2019.

Objectives: Soluble urokinase plasminogen activated receptor (suPAR) is a biomarker that may predict the occurrence of focal segmental glomerulosclerosis (FSGS); however, there is still controversy about whether suPAR can predict FSGS. In this study, we performed a systematic evaluation and meta-analysis to prove whether suPAR can predict FSGS, and to detect a threshold concentration of suPAR that can be used to diagnose FSGS. In addition, a threshold concentration of suPAR for the diagnosis of FSGS was proposed.

Objective: To compare robot-assisted surgery and conventional laparoscopy for gynecologic oncology regarding intra- and post-operative outcomes.

Methods: A retrospective study was performed on consecutive patients with gynecologic oncology from February 2014 to October 2017 at Gansu Provincial Hospital, China. Multivariable linear and logistic regression models were performed to explore the difference between two surgeries in the surgical outcomes after adjusting for potential confounders.

Purpose: The aim of this meta-analysis was to compare high inferior mesenteric artery (IMA) ligation (HL) with low IMA ligation (LL) for the treatment of colorectal cancer and to evaluate the lymph node yield, survival benefit, and safety of these surgeries.

Methods: PubMed, Embase, Cochrane Library, Web of Science, and China Biomedical Literature Database (CBM) were systematically searched for relevant articles that compared HL and LL for sigmoid or rectal cancer. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) for dichotomous outcomes and the weighted mean difference (WMD) for continuous outcomes.

Background: The aim of this study was to compare radiofrequency ablation (RFA) with minimally invasive liver surgery (MIS) in the treatment of small hepatocellular carcinoma (SHCC) and to assess short-term and long-term clinical outcomes.

Methods: PubMed, Embase, Cochrane Library, Web of science, and CBM were systematically searched for articles from inception to July 2018, comparing RFA and MIS in SHCC treatment. We evaluated overall survival (OS), disease-free survival (DFS), local recurrence, and complication rates, as well as hospitalization duration and operation times.

The aim of this study was to evaluate and compare the intestinal function recovery time and other short-term outcomes between robotic-assisted total mesorectal excision (R-TME) and laparoscopic total mesorectal excision (L-TME) for rectal cancer. This is a retrospective study using a prospectively collected database. Patients' records were obtained from Gansu Provincial Hospital between July 2015 and October 2017.

Objective: To compare the effectiveness and safety of suprapubic tube drainage (SPT) with those of transurethral catheterization (TUC) after robot-assisted radical prostatectomy (RARP).

Methods: We searched PubMed, EMBASE, Cochrane Library, CNKI, VIP, WanFang Data and China Biology Medicine Disc from their inception to December 2017 for randomized controlled trials and cohort studies comparing the effectiveness and safety of SPT and TUC after RARP. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies, followed by a meta-analysis with the RevMan 5.

This meta-analysis aimed to compare the effectiveness of the suprapubic drainage and urethral catheterization after robot-assisted radical prostatectomy (RARP). PubMed, EMBASE, Cochrane Library and China Biology Medicine disc were systematically researched from their inception to December 2017. We selected randomized controlled trials, cohort studies comparing suprapubic tube with urethral catheter drainage in RARP patients.

Aim: The robotic technique has been established as an alternative approach to laparoscopy in colorectal surgery. The aim of this study was to compare short-term outcomes of robot-assisted and laparoscopic surgery in colorectal cancer.

Methods: The cases of robot-assisted or laparoscopic colorectal resection were collected retrospectively between July 2015 and October 2017.

Objective: To determine factors associated with smoking relapse in men who survived from their first stroke.

Methods: Data were collected through face to face interviews with stroke patients in the hospital, and then repeated every three months via telephone over the period from 2010 to 2014. Kaplan-Meier method and competing risk model were adopted to estimate and predict smoking relapse rates.

Continued smoking following stroke is associated with adverse outcomes including increased risk of mortality and secondary stroke. The aim of this study was to examine the long-term trends in smoking behaviors and factors associated with smoking relapse among men who survived their first-ever stroke. Data collection for this longitudinal study was conducted at baseline through face-to-face interviews and follow-up was completed every 3 months via telephone, beginning in 2010 and continuing through 2014.

Objective: To determine the relationship between lesion locations and quality of life (QOL) in patients with ischemic stroke.

Methods: The QOL of 456 stroke survivors was assessed two years after the occurrence of stroke. The EQ-5D was used for measuring QOL.

Objective: To determine the association between smoking and ischemic stroke recurrence.

Methods: We conducted a prospective follow-up study of patients with first incidence of stroke. A competing risks model was used to establish the association between smoking and stroke recurrence.
