BackgroundAchilles tendinopathy is a common problem, but its exact aetiology remains unclear.ObjectiveTo evaluate the association between potential clinical risk factors and Achilles tendinopathy.DesignSystematic review.Data sourcesThe databases Embase, MEDLINE Ovid, Web of Science, Cochrane Library and Google Scholar were searched up to February 2018.Eligibility criteriaTo answer our research question, cohort studies investigating risk factors for Achilles tendinopathy in humans were included. We restricted our search to potential clinical risk factors (imaging studies were excluded).ResultsWe included 10 cohort studies, all with a high risk of bias, from 5111 publications identified. There is limited evidence for nine risk factors: (1) prior lower limb tendinopathy or fracture, (2) use of ofloxacin (quinolone) antibiotics, (3) an increased time between heart transplantation and initiation of quinolone treatment for infectious disease, (4) moderate alcohol use, (5) training during cold weather, (6) decreased isokinetic plantar flexor strength, (7) abnormal gait pattern with decreased forward progression of propulsion, (8) more lateral foot roll-over at the forefoot flat phase and (9) creatinine clearance of <60 mL/min in heart transplant patients. Twenty-six other putative risk factors were not associated with Achilles tendinopathy, including being overweight, static foot posture and physical activity level.ConclusionFrom an ocean of studies with high levels of bias, we extracted nine clinical risk factors that may increase a person’s risk of Achilles tendinopathy. Clinicians may consider ofloxacin use, alcohol consumption and a reduced plantar flexor strength as modifiable risk factors when treating patients with Achilles tendinopathy.Trial registration numberCRD42017053258.

Abstract BACKGROUND: Post-thrombotic syndrome (PTS) is the most common long-term complication in pediatric deep venous thrombosis (DVT), affecting approximately 25% of children with an extremity DVT. PTS leads to a high physical, psychological and financial burden in affected patients. Although several risk factors have been associated with the development of pediatric PTS, few of them have been validated in the pediatric literature. A better understanding of the prognostic factors leading to PTS is a vital step for early identification of those children at greatest risk in order to develop risk-stratified interventions aimed at preventing this complication. AIM: To perform a systematic review and meta-analysis of available published evidence from the pediatric literature on prognostic factors for pediatric PTS. METHODS: A systematic search of MEDLINE, EMBASE, and the Cochrane Library from 1960 to December 2017 was performed. MeSH terms and search strategy employed were as follows: "postthrombotic syndrome" OR "postphlebitic syndrome" AND "all child 0-18 years" AND "young adult 19-24 years". A study was eligible for inclusion if it evaluated the development of PTS in pediatric patients (<21 years of age) with a confirmed extremity DVT and reported on at least one prognostic factor for the development of PTS. Single case reports, narrative reviews, and commentaries were excluded. Studies assessing the efficacy/safety of thrombolysis, and studies including patients >21 years of age with outcomes not reported by age group, were also excluded. Two reviewers independently screened all studies and extracted the data of interest. Data were analyzed using STATA v.15 statistical software. Meta-analyses were conducted for risk factors reported in at least three studies. Summary odds ratios (ORs) and 95% confidence intervals (CI) were calculated from the effect estimates from the individual studies using a random effects model. Statistical heterogeneity was quantified by I2 statistic. RESULTS: A total of 12 studies met the final inclusion criteria (Figure 1), nine cohort studies, two cross-sectional studies, and one case-control study. These studies reported a total of 1,160 patients with venous thromboembolism (VTE), of whom 938 (81%) were assessed for PTS (Table 1). Median age across studies ranged from 0.02 - 15.5 years. VTE was considered provoked in nearly 80% of patients. The most common reported risk factor for VTE was the presence of a central venous catheter (CVC, 54%) followed by congenital heart disease (26%). PTS was diagnosed in 46% (n=434) of patients with an extremity DVT. The median time from DVT diagnosis to PTS diagnosis ranged from 12 to 33 months across studies. Among studies reporting this information, mild PTS was most frequently diagnosed, followed by moderate and severe PTS (35%, 5% and 0.6% of patients respectively). Most common prognostic factors associated with PTS in individual studies included patient characteristics: age and gender; and DVT characteristics: recurrent DVT, symptomatic DVT, DVT degree of occlusion, and time between DVT diagnosis and PTS assessment. Three studies investigated the association of elevated factor VIII and d-dimer levels with PTS. Elevated levels of these biomarkers were found to be associated with development of adverse VTE outcomes in one study but this finding was not confirmed in the other studies. Meta-analysis of reported prognostic factors identified the presence of a CVC and occlusive DVT as significant risk factors for the development of pediatric PTS (OR= 1.8, 95%CI=1.08-2.98, and OR=1.89, 95%CI=1.04-3.46 respectively; Figure 2). CONCLUSION: Among 12 studies evaluating prognostic factors for PTS in children and meeting criteria for this meta-analysis, CVC-related DVT and complete occlusion were associated with pediatric PTS. Overall, high-quality evidence on pediatric PTS is lacking. Collaborative prospective cohort studies and trials that use validated pediatric PTS measures and standardized prognostic factor definitions are needed to better understand the risk factors associated with PTS.

Abstract Objective: Postoperative cerebrospinal fluid (CSF) leakage represents a challenge even for experienced pituitary surgeons. We aimed to quantitatively synthesize data from studies regarding the risk factors for postoperative CSF leakage after transsphenoidal surgery (TSS) for pituitary adenoma (PA).Methods: PubMed, Web of Science, The Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), Wanfang database, and VIP database were searched for case–control and cohort studies, focusing on the risk factors associated with postoperative CSF leakage after TSS for PA. Pooled odds ratios (ORs) and 95% confidence intervals were calculated to determine the risk factors.Results: A total of 34 case–control and cohort studies involving a total of 9,144 patients with PA were included in this systematic review. The overall rate of postoperative CSF leakage after TSS for PA was 5.6%. Tumor size, adenoma consistency, revision surgery, and intraoperative CSF leakage were independent risk factors for postoperative CSF leakage (ORs, 3.18–6.33). By contrast, the endoscopic approach showed a slight protective benefit compared with the microscopic approach in TSS (OR, 0.69).Conclusions: This review provides a comprehensive overview of the quality of the evidence base, informing clinical staff of the importance of screening risk factors for postoperative CSF leakage after TSS for PA. More attention should be paid to PA patients at high risk for CSF leakage after TSS to reduce complications and improve prognosis.

Midlife Risk Factors

Objective: The aim of this study is to assess the association between midlife risk factors and dementia. Methods: PubMed and Cochrane library were systematically searched on May 24, 2018, to retrieve prospective cohort studies. The summary Relative Risk (RR) and 95% Confidence Interval (CI) were calculated by the random-effect model to explore the association between midlife risk factors and dementia. Sensitivity analysis and meta-regression were conducted to explore the source of heterogeneity. Publication bias was examined using Begg's and Egger's tests. Results: Thirty-four prospective cohort studies were included, among which 24 were eligible for metaanalysis. A total of 159,594 non-demented adults were enrolled at baseline before 65 years and 13,540 people were diagnosed with dementia after follow-up. The pooled results revealed that five factors could significantly increase the dementia risk by 41 to 78%, including obesity (RR, 1.78; 95% CI: 1.31-2.41), diabetes mellitus (RR, 1.69; 95% CI: 1.38-2.07), current smoking (RR, 1.61; 95%, CI: 1.32-1.95), hypercholesterolemia (RR, 1.57; 95% CI: 1.19-2.07), and hypertension (borderline blood pressure RR, 1.41; 95% CI: 1.23-1.62 and high Systolic Blood Pressure (SBP) RR, 1.72; 95% CI: 1.25-2.37). However, the sensitivity analyses found that the results of hypercholesterolemia and high SBP were not reliable, which need to be confirmed by more high-quality studies. No influences due to publication bias were revealed. In the systematic review, another three factors (hyperhomocysteinemia, psychological stress, and heavy drinking) were found to be associated with elevated dementia risk. In addition, physical exercise, a healthy diet, and hormone therapy in middle age were associated with the reduction of dementia risk. Conclusions: Middle-aged people with obesity, diabetes, hypertension, or hypercholesterolemia, and current smokers in midlife are at higher risk of developing dementia later in life.
