Abstract
OBJECTIVE Platelet-to-lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) have been reported to be related to atherosclerosis. The relationship between PLR, NLR, and carotid atherosclerotic plaque in young patients with newly diagnosed type 2 diabetes has not been clinically reported. This study aimed to analyze the relationship between PLR, NLR, and carotid plaques in young patients with newly diagnosed type 2 diabetes. METHOD The total 268 patients were divided into the intima-media-thickening (IMT) group (116 cases) and plaque group (152 cases). The plaque group was divided into grade I (62 cases), grade II (47 cases), and grade III groups (43 cases). The counts of platelets, neutrophils, and lymphocytes were determined. RESULTS The diagnostic effect of PLR and NLR was evaluated by the receiver-operating characteristic curve (ROC) and areas under the curve (AUC). The PLR and NLR values in the observation group were higher than those in the control group; these two values in the plaque group were also higher than those in the IMT group. The two values in the grade III plaque group were higher than those in grade II. The values in the grade II plaque group were also higher than those in the grade I plaque group. The ROC of PLR and NLR were 0.722 and 0.653, and the AUC of PLR and NLR were 111.086 and 2.240. PLR yielded a sensitivity of 0.789 and a specificity of 0.612. Neutrophil-lymphocyte ratio yielded a sensitivity of 0.809 and a specificity of 0.511. CONCLUSION The PLR and NLR may be related to carotid inflammation in patients and positively correlated with carotid plaque.

Abstract
OBJECTIVE To detect the serum procalcitonin (PCT) level and determine its relationship with the infarct volume in young patients with acute cerebral infarction. METHODS According to the infarct volume, young patients with acute cerebral infarction were divided into large group, intermediate group, and small group. The severity of clinical symptoms was determined according to the National Institute of Health Stroke Scale (NIHSS) score. Healthy young people were selected as the control group. Serum PCT levels were measured. The relationship among PCT, volume, and NIHSS score was analyzed. RESULTS PCT in observation group was significantly higher than that in control group (t = 6.879, P = 0.011), and PCT in severe group was significantly higher than in mild group (t = 6.978, P = 0.016). PCT in large cerebral infarction group was higher than that in intermediate and small-size infarct group (P = 0.0036 and P < 0.0001, respectively), and PCT in intermediate cerebral infarction group was higher than that in small-size infarct group (P = 0.0024). In observation group, the PCT level was positively correlated with both NIHSS (r = 0.793, P = 0.022) and infarction volume (r = 0.649, P = 0.007). CONCLUSION The level of PCT in young patients with acute cerebral infarction may be related to the inflammatory reaction of the cerebral artery and positively related to the volume of cerebral infarction and NIHSS score. To some extent, PCT concentration can predict the disease severity of acute cerebral infarction.

Front Public Health 2020; 8:400. [PMID: 33072681 PMCID: PMC7538625 DOI: 10.3389/fpubh.2020.00400] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Accepted: 07/07/2020] [Indexed: 12/23/2022] Open
Abstract
Objectives: The objective of this study was to estimate the prevalence of dyslipidemia and associated influencing factors in young adults in the southeastern coastal area of China. Methods: This study adopted a cross-sectional survey and included 7,859 young people who underwent examinations at three hospitals in Wenzhou, Zhejiang Province, China. All subjects completed a questionnaire in the form of face-to-face interviews and underwent anthropometric measurements and biochemical tests. The continuous data are presented as the means ± standard deviations and were compared using Student's t-tests. The categorical variables are presented as proportions. The influencing factors associated with dyslipidemia were evaluated through a multivariate logistic regression. Results: The prevalence of dyslipidemia among young adults aged 18-45 years in the southeastern coast of China was high with 7.1, 15.0, 22.9, and 4.0% for high-total cholesterol (TC), high-triglyceride (TG), low-high-density lipoprotein cholesterol (HDL-C), and high-low-density lipoprotein cholesterol (LDL-C). Among those with dyslipidemia, a statistically significant difference in sex was observed, and all types of dyslipidemia were associated with smoking and alcohol consumption. However, those with high-TG, high-LDL, and low-HDL levels did not significantly differ in education level or occupation. The presence of dyslipidemia was significantly associated with increased age, the male sex (OR: 1.85, 95% CI: 1.39-2.21), smoking (OR: 2.02, 95% CI: 1.98-2.13), alcohol consumption (OR: 1.33, 95% CI: 1.16-1.63), overweight or obesity (OR: 2.01, 95% CI: 1.79-2.41), and intellectual work (OR: 1.36, 95% CI: 1.11-1.72). Conclusion: The prevalence of dyslipidemia among young adults aged 18-45 years in the southeastern coast of China was high. To prevent dyslipidemia at an early age, it is essential to conduct effective intervention programs targeting risk factors and to implement routine screening programs.

Abstract
INTRODUCTION Norwegian Stroke in the Young Study (NOR-SYS) is a three-generation research program of young ischaemic stroke. In this study, we assessed ischaemic stroke incidence, education and work status among young stroke patients. Furthermore, we evaluated the participation of family members for future validated information on hereditary cardiovascular events. PATIENTS AND METHODS Patients aged 15-60 years with radiologically verified acute ischaemic stroke, admitted to Haukeland University Hospital in Bergen, Norway from 2010 to 2015, were included. Patients' partners, common offspring ≥ 18 years and biological parents of patients and partners were invited to participate. Ischaemic stroke incidence was analysed with respect to year, age and sex using multiple logistic regression. RESULTS A total of 385 patients, 260 partners (80.0%) and 414 offspring (74.6%) were clinically examined. The mean annual ischaemic stroke incidence rate was 30.2 per 100,000. Incidence was higher in men, and the difference was accentuated with increasing age (p = 0.008). There was no sex difference in educational status (p = 0.104) in contrast to work status (p < 0.001) for patients. In all, 84.1% of men worked, and of these, 80.3% are fulltime. In all, 74.4% of women worked, and of these, 52.9% are fulltime. Parents participated by returning a questionnaire. For patients, 91 fathers (55.2%) and 142 mothers (57.3%) participated. For partners, 48 fathers (38.4%) and 68 mothers (40.2%) participated. CONCLUSION The mean annual incidence rate of young stroke was 30.2 per 100,000, and the incidence rate was higher in men. Work status was high among both sexes. Active participation rates were high for patients, partners and offspring.

Burden, clinical outcomes and predictors of time to in hospital mortality among adult patients admitted to stroke unit of Jimma university medical center: a prospective cohort study. BMC Neurol 2019; 19:213. [PMID: 31470811 PMCID: PMC6716869 DOI: 10.1186/s12883-019-1439-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Accepted: 08/21/2019] [Indexed: 12/19/2022] Open
Abstract
Background The global burden of stroke epidemiology is changing rapidly. Over the 1990–2013 periods, there was a significant increase in the absolute number of deaths and incident events of stroke. The burden of stroke varies in Ethiopia between regions and over time. Hence, this study was aimed to assess the burden, clinical outcomes and predictors of time to in hospital mortality among stroke patients. Methods A prospective cohort study was carried at stroke unit of Jimma University Medical Center (JUMC) from March 10–July 10, 2017. The outcome of interest was mortality and time to death. Data was analyzed using SPSS version 20. Multivariable Cox regression was used to identify the predictors of in hospital mortality and time to death from hospital arrival. Predictor variable with P < 0.05 was considered statistically significant. Results A total of 116 eligible stroke patients were followed over 4 months. The mean age of patients was 55.1 + 14.0 years and males comprised of 73 (62.9%). Stroke accounted for 16.5% of total medical admissions. Among the 116 patients with stroke, 91 (78.4%) were discharged alive making in hospital mortality rate of 25 (21.6%). The median time of in hospital mortality and length of hospital stay after admission of the patients were 4.38 days and 9.21 days, respectively. The prominent suspected immediate cause for in hospital mortality was increased intracranial pressure in 17 (68.0%) followed by respiratory failure secondary to aspiration pneumonia in 11 (44.0%) patients. Brain edema (AHR: 6.27, 95% CI: 2.50–15.76), urine incontinence (AHR: 3.48, 95% CI: 1.48–8.17), National Institute of Health Stroke Scale (NIHSS) > 13 during hospital arrival (AHR: 22.58, 95% CI: 2.95–172.56) and diagnosis of stroke clinically alone (AHR: 4.96, 95% CI: 1.96–12.54) were the independent predictors of time to in hospital mortality. Conclusions The mortality rate of stroke in this setup was comparable with other low- and middle-income countries (LMICs). There is an urgent need to establish well equipped and staffed stroke units in the country in addition to strengthening the already existing one’s. Furthermore, future work must be designed to identify the barriers to improve stroke outcomes and recovery.

Abstract
Rates of stroke and obesity have increased in recent years. This study aimed to determine the body mass index (BMI) of fatal stroke cases amongst young adults, their clinical characteristics and the association with BMI with risk factors. All cases aged 15-44 years where death was attributed to stroke for whom BMI was available were retrieved from the National Coronial Information System (1/1/2009-31/12/2016). 179 cases were identified: haemorrhagic (165), ischaemic (5), thrombotic (6), mycotic (3), embolic (0). Proportions in each BMI category were: underweight (5.6%), normal weight (37.4%), overweight (27.4%), obese (29.6%). There was a significant linear trend in the proportion of subarachnoid haemorrhages as BMI increased (p < 0.05), and between higher BMI and hypertension (p < 0.001). There were no group differences in cardiomegaly or left ventricular hypertrophy where known causes were other than hypertension, cardiomyopathy, severe coronary artery atherosclerosis, endocarditis or cerebral arteries atherosclerosis. A history of alcoholism (p < 0.01) was less likely with higher BMI. There was no association between BMI and previous stroke, diabetes, vasculitis, gravid/post-partum, tobacco use, psychostimulant use or injecting drug use. Overweight and obese cases were prominent among young fatalities of stroke. Reducing rates of obesity, and associated hypertension, would be expected to reduce the escalating stoke rates among young adults.

Abstract
Stroke is one of the most devastating pathologies of the early twenty-first century demonstrating 1-month case-fatality rates ranging from 13 to 35% worldwide. Though the majority of cases do occur in individuals at an advanced age, a persistently increasing portion of the patient cohorts is affected early in life. Current studies provide alarming statistics for the incidence of "young" strokes including adolescents. Young stroke is a multifactorial disease involving genetic predisposition but also a number of modifiable factors, the synergic combination of which potentiates the risks. The article analyzes the prevalence and impacts of "traditional" risk factors such as sedentary lifestyle, smoking, abnormal alcohol consumption, drug abuse, overweight, hypertension, abnormal sleep patterns, and usage of hormonal contraceptives, among others. Further, less explored risks such as primary vascular dysregulation and associated symptoms characteristic for Flammer syndrome (FS) are considered, and the relevance of the FS phenotype for the stroke predisposition at young age is hypothesized. Considering the high prevalence of known genetic and modifiable risk factors in the overall predisposition to the young stroke, the risk mitigating measures are recommended including innovative screening programs by application of specialized questionnaires and biomarker panels as well as educational programs adapted to the target audiences such as children, adolescents, and young adults.

Abstract
Background: The diagnostic value of cerebrospinal fluid (CSF) analysis in juvenile stroke, i.e., stroke in young adult patients, is not well studied. We sought to determine the therapeutic impact of routine CSF-analysis in young adults with acute ischemic stroke or transient ischemic attack (TIA). Methods: We abstracted data from patients with acute cerebral ischemia aged 18–45 years who were consecutively admitted to our stroke center between 01/2008 and 12/2015. We routinely performed CSF-analysis in patients with hitherto unknown stroke etiology after complete diagnostic work up. We assessed the frequency and underlying causes of abnormal CSF-findings and their impact on secondary stroke prevention therapy. Results: Among 379 patients (median [IQR:IQR3-IQR1] age 39 [10:43-33] years, 48% female) with acute ischemic stroke (n = 306) or TIA (n = 73), CSF analysis was performed in 201 patients (53%). Of these, 25 patients (12.4 %) had CSF pleocytosis (leucocyte cell count ≥ 5 Mpt/L), that was rated as non-specific (e.g., traumatic lumbar puncture, reactive pleocytosis) in 22 patients. Only 3 patients (1.5% of all patients who underwent CSF-analysis) with CSF-pleocytosis had specific CSF-findings that were related to stroke etiology and affected secondary stroke prevention therapy. Imaging findings had already suggested cerebral vasculitis in two of these patients. Conclusions: The diagnostic yield of routine CSF-analysis in juvenile stroke was remarkably low in our study. Our data suggest that CSF-analysis should only be performed if further findings raise the suspicion of cerebral vasculitis.

The proportion of cancer-related entries in PubMed has increased considerably; is cancer truly "The Emperor of All Maladies"? PLoS One 2017; 12:e0173671.

Abstract
In this work, the public database of biomedical literature PubMed was mined using queries with combinations of keywords and year restrictions. It was found that the proportion of Cancer-related entries per year in PubMed has risen from around 6% in 1950 to more than 16% in 2016. This increase is not shared by other conditions such as AIDS, Malaria, Tuberculosis, Diabetes, Cardiovascular, Stroke and Infection some of which have, on the contrary, decreased as a proportion of the total entries per year. Organ-related queries were performed to analyse the variation of some specific cancers. A series of queries related to incidence, funding, and relationship with DNA, Computing and Mathematics, were performed to test correlation between the keywords, with the hope of elucidating the cause behind the rise of Cancer in PubMed. Interestingly, the proportion of Cancer-related entries that contain “DNA”, “Computational” or “Mathematical” have increased, which suggests that the impact of these scientific advances on Cancer has been stronger than in other conditions. It is important to highlight that the results obtained with the data mining approach here presented are limited to the presence or absence of the keywords on a single, yet extensive, database. Therefore, results should be observed with caution. All the data used for this work is publicly available through PubMed and the UK’s Office for National Statistics. All queries and figures were generated with the software platform Matlab and the files are available as supplementary material.
