Assessment of the Performances of Adaptive Neuro-Fuzzy Inference System and Two Statistical Methods for Diagnosing Coronary Artery Disease.

Background: The accurate diagnosis of cardiac disease is vital in managing patients' health. Data mining and machine learning techniques play an important role in the diagnosis of heart disease. We aimed to examine the diagnostic performances of an adaptive neuro-fuzzy inference system (ANFIS) for predicting coronary artery disease and compare this with two statistical methods: flexible discriminant analysis (FDA) and logistic regression (LR). Methods: The data of this study is the result of descriptive-analytical research from the study of Mashhad. We used ANFIS, LR, and FDA to predict coronary artery disease. A total of 7385 subjects were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study. The data set contained demographic, serum biochemical parameters, anthropometric, and many other variables. To evaluate the ability of trained ANFIS, LR, and FDA models to diagnose coronary artery disease, we used the Hold-Out method.For analyzing data, we used SPSS v25, R 4.0.4, and MATLAB 2018 software. Results: The accuracy, sensitivity, specificity, Mean squared error (MSE) , and area under the roc curve (AUC) for ANFIS were 83.4%, 80%, 86%, 0.166 and 83.4%. The corresponding values based on the LR method were 72.4%, 74%, 70% , 0.175 and 81.5% and for the FDA method, these measurements were 77.7%, 74%, 81%, 0.223, and 77.6%, respectively. Conclusion: There was a significant difference between the accuracy of these three methods. The present findings showed that ANFIS was the most accurate method for diagnosing coronary artery disease compared with LR and FDA methods. Thus, it could be a helpful tool to aid medical decision-making for the diagnosis of coronary artery disease.

Orthostatic hypertension and major adverse events: a systematic review and meta-analysis.

AIMS: The role of orthostatic hypertension (OHT) in cardiovascular disease (CVD) and mortality is unclear. We aimed to determine if this association exists through a systematic review and meta-analysis. METHODS AND RESULTS: Study inclusion criteria included: (i) any observational/interventional studies of participants aged ≥18 years (ii) that assessed the relationship between OHT and (iii) at least one outcome measure-all-cause mortality (primary outcome), coronary heart disease, heart failure, stroke/cerebrovascular disease, or neurocognitive decline. MEDLINE, EMBASE, Cochrane, clinicaltrials.gov, and PubMed were independently searched by two reviewers (inception-19 April 2022). Critical appraisals were conducted using the Newcastle-Ottawa Scale. Random-effects meta-analysis was performed using a generic inverse variance method, and narrative synthesis or pooled results were presented as an odds or hazards ratio (OR/HR), with 95% confidence interval. Twenty studies (n = 61 669; 47.3% women) were eligible, of which 13 were included in the meta-analysis (n = 55 456; 47.3% women). Median interquartile range (IQR) follow-up for prospective studies was 7.85 (4.12, 10.83) years. Eleven studies were of good quality, eight fair, and one poor. Relative to orthostatic normotension (ONT), systolic OHT (SOHT) was associated with a significant 21% greater risk of all-cause mortality (HR: 1.21, 1.05-1.40), 39% increased risk of CVD mortality based on two studies (HR: 1.39, 1.05-1.84), and near doubled odds of stroke/cerebrovascular disease (OR: 1.94, 1.52-2.48). The lack of association with other outcomes may be due to weak evidence or low statistical power. CONCLUSION: Patients with SOHT may have higher mortality risk relative to those with ONT and increased odds of stroke/cerebrovascular disease. Whether interventions can reduce OHT and improve outcomes should be explored.

Orthostatic hypertension (OHT) is defined as an arbitrary rise in upper (systolic) and/or lower (diastolic) blood pressure readings on standing. We performed a thorough literature search and combined the evidence of impact of OHT on future adverse events, including death, heart attack, heart failure, stroke, falls, and impaired cognition. We found the following:Twenty studies that investigated the association between OHT and future adverse events. Of these, 13 were eligible to be included in the combined evidence (meta-analysis). This formed a total sample of 61 669 participants (47.3% women), of which 55 456 (47.3% women) were included in the meta-analysis.Systolic OHT (SOHT) was associated with a significant 21% increased risk for death from any cause, a 39% greater risk of death due to heart and blood vessel disease and near doubled odds of stroke or brain vessel disease. Furthermore, three of four studies found a significant association between SOHT and impaired cognition. Diastolic OHT was not found to be associated with these outcomes. The lack of association with other outcomes investigated may be due to weak evidence.Eleven studies were of good quality, eight fair, and one poor. Differences in study design, study criteria, and study populations mean that the results need interpreting with caution. Future robust studies can build on this evidence to assess if treatment to reduce OHT would improve future outcomes.

Hyaluronic acid-rich burger separator edible disc prepared from slaughterhouse waste.

In this study, the edible films from chicken feet (CF), ovine muscle fascia (MF), and bovine bone gelatin (Gel) were prepared and their characteristics were analyzed, and we also evaluated the sensory quality of raw and cooked hamburgers using the edible films. The quantities of the CF and MF hyaluronic acid were evaluated using colorimetry and spectrophotometry. The CF, MF, and Gel films were prepared by solvent casting method. Results indicated that the concentration of hyaluronic acid in CF (124.11 ppm) was greater than MF (101.11 ppm). The antioxidative property of the CF film (18.47%) was greater than the Gel (1.88%) and MF (Undetectable) film. The CF film was more resistant to water vapor permeability (2.75 × 10-9 g/m.s.pa) than the MF (1.57 × 10-8 g/m.s.pa) and Gel (1.5 × 10-7 g/m.s.pa) films. The Gel film had more appropriate mechanical properties than CF and MF films. The films kept burgers patties independent from one another and prevented them from sticking and freezing together. MF and CF films were able to promote the organoleptic properties of raw and cooked hamburgers in taste and texture.

Edible hyaluronic acid-rich burger separator discs prepared from slaughterhouse waste.

In this study, edible films from chicken feet extract (CF), ovine muscle fascia extract (MF), and bovine bone gelatin powder (Gel) were prepared and their characteristics were analyzed. We also used the films as separators of burger cuts and evaluated the organoleptic characteristics of cooked burgers. Hyaluronic acid quantities of CF and MF were measured using colorimetric and spectrophotometry. Results indicated that the concentration of hyaluronic acid in CF (124.11 ppm) was greater than MF (101.11 ppm). The antioxidative property of the CF film (18.47%) was greater than the Gel (1.88%) and MF (Undetectable) films. The CF film was more resistant to water vapor permeability (2.75 × 10-9 g/m.s.pa) than the MF (1.57 × 10-8 g/m.s.pa) and Gel (1.5 × 10-7 g/m.s.pa) films. The Gel film had more appropriate mechanical properties than CF and MF films. The films kept burgers patties independent from one another and prevented them from sticking and freezing together. MF and CF films were able to promote the organoleptic properties of cooked burgers in taste and texture.

Gender differences in mortality of hospitalised stroke patients. Systematic review and meta-analysis.

OBJECTIVE: Gender differences in mortality after stroke remains unclear in the current literature. We therefore aimed to systematically review the gender differences in mortality up to five years after ischaemic (IS) or haemorrhagic stroke (HS) to address this evidence gap. METHODS: The literature was systematically searched using Ovid EMBASE, Ovid Medline, and Web of Science databases, from inception-November 2021. The quality of evidence was appraised using the CASP Cohort-study checklist. Unadjusted and adjusted odds and hazard ratios were meta-analysed, separately for IS and HS and a subgroup analysis of age-stratified mortality data was conducted. RESULTS: Forty-one studies were included (n = 8,128,700; mean-age 68.5 yrs; 47.1% female). 37 studies were included in meta-analysis (n = 8, 8008, 110). Compared to men, women who had an IS had lower mortality risk in-hospital (0.94; 95%CI 0.91-0.97), at one-month (0.87; 95%CI 0.77-0.98), 12-months (0.94; 95%CI 0.91-0.98) and five-years (0.93 95%CI 0.90-0.96). The subgroup analysis showed that this gender difference in mortality was present in women ≥ 70 years up to one-month post-IS (in-hospital: 0.94; 95%CI 0.91-0.97; one-month: 0.87; 95% CI 0.77-0.98), however, in women < 70 years this difference was no longer present. Nevertheless, analysis of crude data showed women were at higher risk of mortality in-hospital, at 12-months and five-years (in-hospital: 1.05; 95%CI 1.03-1.07, 12-months: 1.10; 95%CI 1.06-1.14, five-years: 1.06; 95%CI 1.02-1.10). After HS, women had higher mortality risk in-hospital (1.03; 95%CI 1.01-1.04) however, no gender differences were found post-discharge. CONCLUSION: The gender differences in post-stroke mortality differ by stroke type, age group and follow-up. Crude stroke mortality in women is higher than in men and this appears to be driven by pre-existing comorbidities. In adjusted models, women have a lower mortality risk following IS, independent of duration of follow-up. After HS, women had higher mortality in hospital however, no gender differences after hospital discharge were found.

An Ecological Study Assessing the Relationship between Public Health Policies and Severity of the COVID-19 Pandemic.

Reliance on government-led policies have heightened during the COVID-19 pandemic. Further research on the policies associated with outcomes other than mortality rates remains warranted. We aimed to determine associations between government public health policies on the severity of the COVID-19 pandemic. This ecological study including countries reporting ≥25 daily COVID-related deaths until end May 2020, utilised public data on policy indicators described by the Blavatnik school of Government. Associations between policy indicators and severity of the pandemic (mean mortality rate, time to peak, peak deaths per 100,000, cumulative deaths after peak per 100,000 and ratio of mean slope of the descending curve to mean slope of the ascending curve) were measured using Spearman rank-order tests. Analyses were stratified for age, income and region. Among 22 countries, containment policies such as school closures appeared effective in younger populations (rs = -0.620, p = 0.042) and debt/contract relief in older populations (rs = -0.743, p = 0.009) when assessing peak deaths per 100,000. In European countries, containment policies were generally associated with good outcomes. In non-European countries, school closures were associated with mostly good outcomes (rs = -0.757, p = 0.049 for mean mortality rate). In high-income countries, health system policies were generally effective, contrasting to low-income countries. Containment policies may be effective in younger populations or in high-income or European countries. Health system policies have been most effective in high-income countries.

Reproductive Pattern of Parous Women and the Risk of Cancer in Later Life.

We assessed the risk of any and site-specific cancers in a case-control study of parous women living in northeast Scotland in relation to: total number of pregnancies, cumulative time pregnant, age at first delivery and interpregnancy interval. We analysed 6430 women with cancer and 6430 age-matched controls. After adjustment for confounders, women with increasing number of pregnancies had similar odds of cancer diagnosis as women with only one pregnancy. The adjusted odds of cancer diagnosis were no higher in women with cumulative pregnancy time 50-150 weeks compared to those pregnant ≤ 50 weeks. Compared with women who had their first delivery at or before 20 years of age, the adjusted odds ratio (AOR) among those aged 21-25 years was 0.81, 95% CI 0.74, 0.88; 26-30 years AOR 0.77, 95% CI 0.69, 0.86; >30 years AOR 0.63, 95% CI 0.55, 0.73. After adjustment, the odds of having any cancer were higher in women who had an inter-pregnancy interval >3 years compared to those with no subsequent pregnancy (AOR 1.17, 95% CI 1.05, 1.30). Older age at first pregnancy was associated with increased risk of breast and gastrointestinal cancer, and reduced risk of invasive cervical, carcinoma in situ of the cervix and respiratory cancer.

Country-level determinants of the severity of the first global wave of the COVID-19 pandemic: an ecological study.

OBJECTIVE: We aimed to identify the country-level determinants of the severity of the first wave of the COVID-19 pandemic. DESIGN: Ecological study of publicly available data. Countries reporting >25 COVID-19 related deaths until 8 June 2020 were included. The outcome was log mean mortality rate from COVID-19, an estimate of the country-level daily increase in reported deaths during the ascending phase of the epidemic curve. Potential determinants assessed were most recently published demographic parameters (population and population density, percentage population living in urban areas, population >65 years, average body mass index and smoking prevalence); economic parameters (gross domestic product per capita); environmental parameters (pollution levels and mean temperature (January-May); comorbidities (prevalence of diabetes, hypertension and cancer); health system parameters (WHO Health Index and hospital beds per 10 000 population); international arrivals; the stringency index, as a measure of country-level response to COVID-19; BCG vaccination coverage; UV radiation exposure; and testing capacity. Multivariable linear regression was used to analyse the data. PRIMARY OUTCOME: Country-level mean mortality rate: the mean slope of the COVID-19 mortality curve during its ascending phase. PARTICIPANTS: Thirty-seven countries were included: Algeria, Argentina, Austria, Belgium, Brazil, Canada, Chile, Colombia, the Dominican Republic, Ecuador, Egypt, Finland, France, Germany, Hungary, India, Indonesia, Ireland, Italy, Japan, Mexico, the Netherlands, Peru, the Philippines, Poland, Portugal, Romania, the Russian Federation, Saudi Arabia, South Africa, Spain, Sweden, Switzerland, Turkey, Ukraine, the UK and the USA. RESULTS: Of all country-level determinants included in the multivariable model, total number of international arrivals (beta 0.033 (95% CI 0.012 to 0.054)) and BCG vaccination coverage (-0.018 (95% CI -0.034 to -0.002)), were significantly associated with the natural logarithm of the mean death rate. CONCLUSIONS: International travel was directly associated with the mortality slope and thus potentially the spread of COVID-19. Very early restrictions on international travel should be considered to control COVID-19 outbreaks and prevent related deaths.

SARS-CoV-2 Liability: The Hidden Mystery Behind Its Presentation in Children.

Coronavirus disease 2019 (COVID-19) is now of global concern because of its rapid dissemination across the globe. It is unclear whether COVID-19 is as hazardous as previous coronavirus outbreaks, though there are many overlapping similarities between these viruses. An important similar feature includes the virus's pathogenicity in pediatric populations. Additionally, genetic factors are recognized as important contributors to infectious disease susceptibility. Further understanding of this area can help make sense of the pathogenesis of COVID-19 and the varying clinical spectrums of the disease. The available data suggests that COVID-19 most likely produces mild symptoms in a healthy pediatric population regardless of their age, and recovery appears to occur without serious sequelae in the vast majority. However, the available data regarding the detailed repercussions of COVID-19 in children is very limited. To date, only some theoretical issues could be responsible for the COVID-19 susceptibility in pediatric patients, including a more intact but mature immune system within the respiratory system, possible role of viral interference in pediatric populations that are more often infected with common respiratory viruses, possible role of gut-lung axis, and a respiratory system with different amounts of cellular receptors for COVID-19 virus. Moreover, there is little data available on the genetic risk factors for COVID-19, and future research should aim to cover this gap in knowledge. This chapter aims to summarize the recently published data on the impact of COVID-19 in the pediatric population and to systematically review the available evidence of genetic risk factors for COVID-19.

Hypertensive Disorders of Pregnancy (HDP) and the Risk of Common Cancers in Women: Evidence from the European Prospective Investigation into Cancer (EPIC)-Norfolk Prospective Population-Based Study.

PURPOSE: The purpose was to determine the association between HDP and cancer in a UK cohort. METHODS: Between 1993 and 1997, participants from the EPIC-Norfolk cohort attended baseline health-checks and completed questionnaires, where a history of HDP was collected. Incident cancer cases were identified through NHS record linkage until March 2016. Univariable and multivariable logistic regression analyses were employed to determine the association between HDP and odds of cancer, with adjustment for potential confounders including co-morbidities, sociodemographic, lifestyle and reproductive factors. RESULTS: 13,562 women were included after excluding prevalent cancer cases and women with no pregnancies. 2919 (21.5%) reported HDP and 2615 incident cancers occurred during mean follow up of 19 years. Median age (IQR) at baseline for incident cancer was 60.8 (±14.8) years. Among incident cancer cases, 578 (22.1%) had HDP. In multivariable analyses, HDP had odds ratio (OR) 1.06; 95% CI 0.95-1.18 for incident cancer. The ORs (95% CIs) for common site-specific cancers including breast, colorectal, lung, ovarian and endometrial cancers were 1.06 (0.88-1.28), 1.15 (0.92-1.45), 0.96 (0.68-1.35), 1.30 (0.93-1.83) and 1.16 (0.80-1.67). CONCLUSION: We found no association between HDP and cancer risk. Further studies are required to confirm and account for any underlying genetic factors involved in pregnancy-related exposures and cancer risk.

Early detection of cervical cancer based on high-risk HPV DNA-based genosensors: A systematic review.

Human papillomavirus type (HPV) is a common cause of sexually transmitted disease (STD) in humans. HPV types 16 and 18 as the highest risk types are related with gynecologic malignancy and cervical cancer (CC) among women worldwide. Recently, considerable development of genosensors, which allows dynamic monitoring of hybridization events for HPV-16 and 18, has been a topic of focus by many researchers. In this systematic review, we highlight the route of development of DNA-based genosensory detection methods for diagnosis of high risk of HPV precancer. Biosensor detection methods of HPV-16 and 18 was investigated from 1994 to 2018 using several databases including PubMed, Cochrane Library, Scopus, Google Scholar, SID, and Scientific Information Database. Manual search of references of retrieved articles were also performed. A total of 50 studies were reviewed. By analyzing the most recent developed electrochemical biosensors for the identification of HPV, we observed that the sensor platform fabricated by Wang et al. holds the lowest detection limit reported in the literature for the DNA of HPV-16. Up to this date, optical, electrochemical, and piezoelectric systems are the main transducers used in the development of biosensors. Among the most sensitive techniques available to study the biorecognition activity of the sensors, we highlight the biosensors based fluorescent, EIS, and QCM. The current systematic review focuses on the sensory diagnostic methods that are being used to detect HPV-16 and 18 worldwide. Special emphasis is given on the sensory techniques that can diagnosis the individuals with CC. © 2018 BioFactors, 45(2):101-117, 2019.
