Using Data Mining and Association Rules for Early Diagnosis of Esophageal Cancer.

From 17,000 new cases of esophageal cancer worldwide during last year, 16,000 proved to be fatal. Late or incorrect diagnosis of esophageal cancer cases increases its fatality rate. Today, a data-mining technique can predict the course of the disease with the help of an upto-date technology. With this knowledge, we can reduce esophageal cancer mortality. This study aims to find an association between general characteristics, screening tests, and esophageal cancer based on raw data from the Cancer Research Center within-person interviews, using data mining and classification techniques on mortality. The 5-year medical records of 512 esophageal cancer patients and those with problems related to this cancer, with 50 functional characteristics, were included in this model. In order to provide a prognostic and rule discovery model for esophageal cancer suffering, we used preprocessing EM Algorithm. After accurate identification of the data, WEKA Software tools and Java programming language was used to create Association Rule Classifier and Apriori algorithm for the associated rule discovery. We created 6 significant rules of the association for classification generated by rule miner with 95% and 91% confidence based on screening tests and general attributes, respectively. These substantial rules showed significant association between age, history of medication, smoking, gender, carcinoembryonic antigen (CEA), creatinine, WBCs, and Platelets. The findings of this study can be used as a clue for physicians to consider patients with these characteristics as people who are more likely to develop esophageal cancer and help them for early diagnosis of patients.

Design, development, and evaluation of a registry system for hyperbaric oxygen therapy: A methodological study.

Background and Aims: Hyperbaric oxygen therapy (HBOT), utilizes 100% oxygen at pressures greater than sea-level atmospheric pressure, for the treatment of conditions in which the tissues starve for oxygen. The Undersea and Hyperbaric Medical Society (UHMS) has granted HBOT approval for the treatment of various conditions. On the other hand, applying informatics registry systems can improve care delivery, ameliorate outcomes, and reduce the costs and medical errors for the patients receiving HBOT treatment. Therefore, we aimed to design, develop, and evaluate a registry system for patients undergoing HBOT. Methods: In the first phase, the conceptual and logical models were designed after conducting symposiums with experts and having other experts review the models. In the second phase, the system was developed on the web using ASP.NET  and C# programming languages frameworks. The last phase involved Nielsen's heuristic evaluation method for the system's usability. Five experts evaluated the system, including three health information management specialists and two medical informatics specialists. Results: The hyperbaric patient information registry system (HPIRS) interacts with three types of users-a specialist physician, a nurse, and a system administrator. A scenario for each predefined activity was designed, and all the information was stored in the SQL servers. The five experts independently found 152 issues, of which 84 were duplicates. The 68 distinct issues of the system were then resolved. Conclusions: The design and development of such registry systems can make data available and stored carefully to improve clinical care and medical research and decrease costs and errors. These registries can provide the healthcare systems with E-health applications, improved data management, more secure data transfer, and support for statistical reporting. The implemented heuristic evaluation method can also provide a low-cost and readily available system to fix the issues of the designed systems.

Mucormycosis infection in patients with COVID-19: A systematic review.

INTRODUCTION: Several reports previously described mucormycosis co-infection in patients with COVID-19. As mucormycosis and COVID-19 co-infection might adversely affect patients' outcomes, we aimed to systematically review the related evidence and the subsequent outcomes. METHODS: We conducted a systematic review of relevant articles searching the keywords in the online databases of PubMed, Scopus, Embase, Cochrane, and Web of Science. All the records from the start of the pandemic until June 12th, 2021 underwent title/abstract and then full-text screening process, and the eligible studies were included. We did not include any language or time restrictions for the included studies. RESULTS: We found 31 eligible studies reporting 144 total cases of COVID-19 and mucormycosis co-infection. The nose, cranial sinuses, and orbital cavity were the most commonly involved organs, although the cerebrum, lungs, and heart were also involved in the studies. Pre-existing diabetes mellitus (DM), as well as corticosteroid use, were the most commonly identified risk factors, but other underlying conditions and immunomodulatory drug use were also present in several cases. Aspergillus was the most commonly reported micro-organism that caused further co-infections in patients with concurrent COVID-19 and mucormycosis. As most of the studies were case reports, no reliable estimate of the mortality rate could be made, but overall, 33.6% of the studied cases died. CONCLUSION: Early diagnosis of mucormycosis co-infection in COVID-19 patients and selecting the right treatment plan could be a challenge for physicians. Patients with underlying co-morbidities, immunocompromised patients, and those receiving corticosteroids are at higher risk of developing mucormycosis co-infection and it is crucial to have an eye examination for early signs and symptoms suggesting a fungal infection in these patients.

COVID-19 in Pediatrics: A Systematic Review of Current Knowledge and Practice.

INTRODUCTION: SARS-CoV-2 is the novel coronavirus that causes severe acute respiratory syndrome and could afflict individuals from all walks of life. Children are usually asymptomatic or represent non-specific mild to moderate symptoms; therefore, they often remain undiagnosed and could be potential reservoirs and silent carriers of the virus. Despite the global attention to COVID-19 and its importance in public health, some clinical and paraclinical aspects of this disease in children are still unclear. Thus, we conducted a comprehensive systematic review of available literature to reflect on the current knowledge and practice of the disease among children. METHODS: This study was a systematic review of current evidence conducted in October 2020. We performed a systematic search using the keywords in online databases. The investigation adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist to ensure the reliability and validity of extracted literature and results. RESULTS: We selected and reviewed 23 most related studies out of 1744 identified papers in an initial online search based on the inclusion and exclusion criteria of the present review; of whom 13 were original research studies, and 10 were letters to the editors, commentaries, viewpoints, consensus statements, and perspectives. Although due to the origin of the current pandemic, China was the country with the most publications (12 articles), data from several countries have been included in this review. CONCLUSION: COVID-19 can also affect children and cause systemic disease with several internal organ involvements. However, the prevalence, severity, and diversity of the symptoms in children are less than in adults. Cough and fever appear to be some of the most common symptoms, followed by other symptoms such as gastrointestinal manifestations. Comorbidities increase the risk of severe COVID-19 in children, and those without underlying conditions are very unlikely to suffer from severe disease. Mental health issues such as anxiety and depression due to the isolated situation caused by pandemics are common findings in children of early ages and should be seriously considered in current practice.

The effects of hyperbaric oxygen therapy (HBOT) on coronavirus disease-2019 (COVID-19): a systematic review.

BACKGROUND: Oxygenation serves as a cornerstone in the treatment of COVID-19, and several methods have been extensively studied so far. Herein, we aimed to systematically review the studies discussing hyperbaric oxygen therapy (HBOT) to examine its reported efficacy and adverse events in patients with COVID-19. METHODS: We systematically searched and retrieved the relevant articles using keywords on the online databases, including PubMed, Scopus, Embase, Web of Science, and Cochrane databases up to April 11th, 2021. The retrieved records underwent a two-step title/abstract and full-text screening process, and the eligible papers were identified. National Institutes of health (NIH) quality assessment tool was used for this study. This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO) with ID CRD42021269821. RESULTS: Eight articles from three countries were included. All the included studies had good and fair quality scores, with no poor studies included in this systematic review (Good: n = 5, Fair: n = 3). Studies were divided into clinical trials and case reports/series. Most of the studies used HBOT less than 1.5-2 absolute atmospheres (ATA) for 90 min sessions and thereafter sessions were decreased to 60 min. Trials demonstrated most of the patients recovered after receiving HBOT, and blood oxygen saturation increased after several sessions of HBOT. CONCLUSION: Overall, HBOT seems to be a safe and effective oxygenation method in patients with COVID-19. However, there is limited knowledge and evidence regarding the effects and mechanism of HBOT in COVID-19 treatment, and further evaluations require extensive well-designed studies.

Reinfection risk of novel coronavirus (COVID-19): A systematic review of current evidence.

BACKGROUND: There is recently a concern regarding the reinfection and reactivation of previously reCoVered coronavirus disease 2019 (CoVID-19) patients. AIM: To summarize the recent findings and reports of CoVID-19 reinfection in patients previously reCoVered from the disease. METHODS: This study was a systematic review of current evidence conducted in August 2020. The authors studied the probable reinfection risk of novel coronavirus (CoVID-19). We performed a systematic search using the keywords in online databases. The investigation adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist to ensure the reliability and validity of this study and results. RESULTS: We reviewed 31 studies. Eight studies described reCoVered patients with reinfection. Only one study reported reinfected patients who died. In 26 studies, there was no information about the status of the patients. Several studies indicated that reinfection is not probable and that post-infection immunity is at least temporary and short. CONCLUSION: Based on our review, we concluded that a positive polymerase chain reaction retest could be due to several reasons and should not always be considered as reinfection or reactivation of the disease. Most relevant studies in positive retest patients have shown relative and probably temporary immunity after the reCoVery of the disease.

Assessing the link between head lice infestation and selected cognitive-behavioral factors in a sample of Iranian female adolescents.

BACKGROUND: Head lice infestation is a serious health issue among adolescents in Iran. The primary purpose of the study was to determine the association of head lice infestation with cognitive-behavioral factors in female adolescents. METHODS: The study was cross-sectional, took place between September and October of 2017 in Sarab, East Azerbaijan province, Iran. Using a multi-stage sampling to recruit the study's 226 female adolescents, five of the Sarab's 13 schools were selected through simple random sampling. In the second step, the students were randomly selected using the systematic random sampling method. A survey questionnaire was used to collect the data. FINDINGS: The prevalence rate of head lice was calculated 20.4%, and the subjects with head lice infestation had lower levels of severity, benefits, self-efficacy, and preventive behaviors. Those without head lice infestation reported adhering to preventive behaviors. The perceived severity and self-efficacy were the statistically significant predictors of head lice infestation and use of preventive behaviors. CONCLUSION: Public health authorities, with feedback from the community, must design and implement prevention programs, focusing on mothers and their school-aged children, school principals, and managers of public places as potential change agents. In addition to, perceived severity and self-efficacy should be considered as the key categories when developing these prevention programs.

Adherence to a Health Literacy and Healthy Lifestyle with Improved Blood Pressure Control in Iran.

INTRODUCTION AND AIM: High blood pressure is the leading and most important modifiable risk factor for cardiovascular disease. Health literacy and lifestyle are two paramount key factors behind better control of hypertension. This study was conducted to examine the current situation of health literacy and health-promoting lifestyle and its association with blood pressure control among people affected by hypertension in the population over age 30 of Northwest Iran. PATIENTS AND METHODS: This was a cross-sectional study conducted in October and December 2018 on the over 30-year-old population among subjects suffering from hypertension (n= 210). A self-reported questionnaire was used for assessing health literacy dimensions and lifestyle. RESULTS: In hierarchical linear analysis, the HL explained 33.9% of the variance in healthy lifestyle. Among HL dimensions, the ability to access health information and decision-making were significantly associated with healthy lifestyle. The health literacy dimensions contributed to an additional significant increase in 4.7% of the variance explained in hypertension, furthermore, the health-promoting lifestyle items were explained an additional 14.8% of the hypertension variance. In total, lifestyle and health literacy dimensions were able to explain 21.7% of the variance in hypertension. CONCLUSION: Our study encourages efforts to monitor health literacy in people with hypertension and investigate associations with involvement with health-promoting lifestyle.

Effects of postural and cognitive difficulty levels on the standing of healthy young males on an unstable platform.

Standing on an unstable platform requires continuous effort of the neuro­musculoskeletal system. The aim of the present study is to evaluate the ability to remain standing on an unstable platform at different levels of postural and cognitive difficulty. Healthy young males stood in the sagittal plane on an unstable platform supported by a pair of springs with modifiable stiffness. The balance test also assessed different levels of vision and cognitive function. Linear and nonlinear metrics of standing, based on motion captured kinematic data, were assessed to analyze the stability of standing. Results showed that vision plays a significant role in maintaining balance in terms of linear metrics. Elimination of visual feedback changed the direction of body sway and increased standing instability. Placement of low stiffness springs led to unstable standing. The cognitive dual task, however, had no effect on the stability metrics and merely could be revealed in the simplest test condition. Standing on an unstable platform was closely related to visual feedback and decreasing the spring stiffness significantly reduced stability. The roles of cognitive involvement were subdued by increasing the postural difficulty in standing on an unstable platform.
