Combining pathological and cognitive tests scores: A novel data analytics process to improve dementia prediction models1.

BACKGROUND: The term 'dementia' covers a range of progressive brain diseases from which many elderly people suffer. Traditional cognitive and pathological tests are currently used to detect dementia, however, applications using Artificial Intelligence (AI) methods have recently shown improved results from improved detection accuracy and efficiency. OBJECTIVE: This research paper investigates the efficacy of one type of data analytics called supervised learning to detect Alzheimer's disease (AD) - a common dementia condition. METHODS: The aim is to evaluate cognitive tests and common biological markers (biomarkers) such as cerebrospinal fluid (CSF) to develop predictive classification systems for dementia detection. RESULTS: A data analytics process has been proposed, implemented, and tested against real data obtained from the Alzheimer's Disease Neuroimaging Initiative (ADNI) repository. CONCLUSION: The models showed good power in predicting AD levels, notably from specified cognitive tests' scores and tauopathy related features.

A Narrative Review of Contact Sports Participation in Children and Young Athletes With a Solitary (Functioning) Kidney.

BACKGROUND: Evidence is sparse regarding the incidence or prevalence of renal or genitourinary injuries arising from contact sports. There are currently no World Health Organization or European consensus guidelines relating to the participation in sport for children and young athletes with a solitary (functioning) kidney. PURPOSE: To review the international literature and to make sport-specific recommendations for children and young athletes with a solitary (functioning) kidney participating in sports, based on the overall likelihood of potential renal or genitourinary injury. STUDY DESIGN: Narrative review; Level of evidence, 4. METHODS: A descriptive epidemiological study was conducted of current literature according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Embase, Google Scholar, Cochrane, and PubMed databases were queried from 1975 to 2023, to assess available evidence regarding the prevalence and risk of renal injury through sports participation and guidelines surrounding the participation in sports for children and young athletes with a solitary (functioning) kidney. Methodological quality and certainty of evidence were assessed according to the International Classification of Urological Disease guidelines. RESULTS: A total of 28 publications were identified after database searches and exclusions, comprising 40,889 patients. The majority of papers providing recommendations arose from the United States. Of the recommendations, 79% permitted an unrestricted return to noncontact sports. A return to contact sports is permitted in most instances after physician consultation. CONCLUSION: There is a dearth of good-quality published evidence in the literature relating to sports participation with a solitary (functioning) kidney. Overall, the risk of genitourinary injury in sports is low, and after physician assessment, there is currently no strong evidence to exclude children and young athletes with a solitary (functioning) kidney from full participation in contact and collision sports.

Do five screening tools identify the same number of runners who require pre-exercise medical clearance? SAFER XXXIV.

OBJECTIVES: Currently, there are five international screening tools that are recommended to identify individuals who require pre-exercise medical clearance to reduce the risk of medical encounters during exercise. Therefore, the aim was to determine the percentage of race entrants who are advised to obtain pre-exercise medical clearance and the observed agreement between these five different international pre-exercise medical screening tools. METHODS: In all, 76,654 race entrants from the Two Oceans Marathon (2012-2015) that completed an online pre-race screening questionnaire. Five pre-exercise medical screening tools (American Heart Association (AHA), pre-2015 American College of Sport Medicine (ACSM), post-2015 ACSM, Physical Activity Readiness Questionnaire (PAR-Q), and the European Association of Cardiovascular Prevention and Rehabilitation (EACPR)) were retrospectively applied to all participants. The % (95%CI) race entrants requiring medical clearance identified by each tool and the observed agreement between tools (%) was determined. RESULTS: The % entrants requiring medical clearance varied from 6.7% to 33.9% between the five tools: EACPR (33.9%; 33.5-34.3); pre-2015 ACSM (33.9%; 33.5-34.3); PAR-Q (23.2%; 22.9-23.6); AHA (10.0%; 9.7-10.2); post-2015 ACSM (6.7%; 6.5-6.9). The observed agreement was highest between the pre-2015 ACSM and EACPR (35.4%), for pre-2015 ACSM and PAR-Q (24.8%), PAR-Q and EACPR (24.8%), and lowest between the post-2015 ACSM and AHA (4.1%). CONCLUSION: The percentage of race entrants identified to seek medical clearance (and observed agreement) varied considerably between pre-exercise medical screening tools. Further research should determine which tool has the best predictive ability in identifying those at higher risk of medical encounters during exercise.

Body (dis)satisfaction and health screening behaviors: A systematic review of observational studies.

Engagement in health-promoting behaviors has been argued to be dependent on psychological factors in addition to simply having knowledge or access to resources. We systematically reviewed the evidence for the association between body (dis)satisfaction and health screening behaviors using six electronic databases and supplementary manual searches in the current study. To be included in the review, studies had to be empirical, in any language, and examined the potential link between body (dis)satisfaction and health screening. Findings from the final 16 quantitative and 12 qualitative studies generally suggest that people who were more satisfied or less dissatisfied with their bodies were more likely to engage in health screening. This review also highlighted key gaps in the literature such as the limited studies that included men as participants and the lack of examination of the underlying mechanisms and contingencies of the relationship between body (dis)satisfaction and health screening behaviors.

Presence of Post-traumatic Limps in an Adult Population Diagnosed on a "Catwalk Video": A Comparative Study Between Healthcare and Nonhealthcare Individuals.

Background Walking is an everyday activity but also complex in nature. Gait disorders have the potential to drastically affect an individual's quality of life and their ability to be independent. The causes of gait disorders are numerous. To identify abnormal gait, clinicians utilize gait analysis. The aim of this study is to assess how well individuals can identify limps in postoperative traumatized individuals with lower extremity deformities. Methods Participants observed a video compiled of individuals with various gait abnormalities and severities of limps. In the video, there were nine abnormal gait presentations, four obvious limps, and five subtle limps, while the other 10 gait presentations were normal gaits. Classifications for gait presentations were assigned by the research team. Participants assigned a classification to each limp case presented in the video on a survey. The participants were separated into two groups: those with healthcare experience and lay individuals. A Mann-Whitney U-test was used to compare healthcare experience and lay individuals' ability to identify limps correctly. In addition, the observers were evaluated on their ability to perform a screening diagnosis of a limp. Results A total of 100 participants were included in the study, 46 with healthcare experience and 54 individuals without. All tests, identification of limp and subtle limp, using the Mann-Whitney U-test yielded non-significant differences between healthcare and nonhealthcare experience. Overall lowest correctness between both groups came when attempting to identify subtle limp (healthcare = 57.39%, nonhealthcare = 56.67%) while the highest correctness yield was when identifying limp (healthcare = 96.74%, nonhealthcare = 95.37%). Analysis of the observers' ability to perform a screening diagnosis of limp provided close to gold standard results (sensitivity = 96.0%, specificity = 98.7%, positive predictive value = 99.2%, negative predictive value = 98.4%). Conclusion This study showed that nonhealthcare individuals can accurately perform gait analysis from a video, particularly in identifying the presence of a limp, to a similar extent as individuals with healthcare experience. The implementation of two-dimensional catwalk videos taken from a smartphone is beneficial due to accessibility and cost-effectiveness. It also suggested that limp diagnosis can be done as a screening test, using individuals as the screener.

Willingness for Medical Screening in a Dental Setting-A Pilot Questionnaire Study.

An important way to manage noncommunicable diseases (NCDs) is to focus on prevention, early detection, and reducing associated risk factors. Risk factors can be detected with simple general health checks, which can also be performed in dental clinics. The purpose of this study was to investigate participants' willingness to participate in general health checks at the dentist, in particular the difference in opinion between medical patients and random healthy dental attendees. A total of 100 medical patients from an outpatient internal medicine clinic and 100 dental clinic attendees were included (total of 200 participants). The participants were asked for their opinion using six closed-ended questions. Overall, 91.0% of participants were receptive to information about the risk of diabetes mellitus (DM) and cardiovascular diseases (CVD). The majority (80-90%) was receptive to screening for DM and CVD risk, such as weight and height measurements, blood pressure measurement, saliva testing for CVD and to measure glucose and cholesterol via finger stick. No significant differences were found in the frequencies of the responses between the different groups based on health status, age, sex, or cultural background. This study shows that most participants are willing to undergo medical screening at the dentist for early detection and/or prevention of common NCDs.

Prevalence of Depressive Symptoms Among an Undergraduate Health Sciences Student Population: A Cross-Sectional Study.

PURPOSE: Undergraduate health sciences students are irrefutably liable to intrapersonal tension that may provoke the almost imperceptible onset and incremental expansion of depressive symptoms. Mental health is often a deplorably neglected topic despite posing as a catalyst in many students' academic demise. Thus, the primary objective of this paper is to provide an insight into a multitude of variables that foster depressive symptoms. In doing so, the scope of subclinical depression that could be hindering a student's academic performance shall be illuminated. METHODOLOGY: A cross-sectional study was conducted among health sciences students comprising both genders, any nationality, students 18 years of age or older, and students within their first three years of undergraduate study. The well-established Patient Health Questionnaire-9 was distributed along with a non-standardized questionnaire that inquires about additional risk factors. The chi-square test method was used to associate the dependent and independent variables, and statistical significance was done at p-value ≤ 0.05. FINDINGS: It was observed that 34.8% of participants suffer depressive symptoms. Participants' sex and marital status, among many other factors, like age, program and year of study, are found to be statistically insignificant. Conversely, nationality, university-related workload, smoking, alcohol intake and more are noted to be significantly associated with the development of depressive symptoms. ORIGINALITY: This study is an original work done by the authors to investigate the prevalence of depressive symptoms among undergraduate health sciences students. The non-standardized questionnaire employed has been reviewed to ensure that it is without discrimination of any gender or biased towards any stakeholders.

Exploring Circulating Tumor DNA (CtDNA) and Its Role in Early Detection of Cancer: A Systematic Review.

There is a significant increase in the need for an efficient screening method that might identify cancer at an early stage and could improve patients' long-term survival due to the continued rise in cancer incidence and associated mortality. One such effort involved using circulating tumor DNA (ctDNA) as a rescue agent for a non-invasive blood test that may identify many tumors. A tumor marker called ctDNA is created by cells with the same DNA alterations. Due to its shorter half-life, it may be useful for both early cancer detection and real-time monitoring of tumor development, therapeutic response, and tumor outcomes. We obtained 156 papers from PUBMED using the MeSH approach in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) criteria and ten articles from additional online resources. After removing articles with irrelevant titles and screening the abstract and full text of the articles that contained information unrelated to or not specific to the title query using inclusion and exclusion criteria, 18 out of 166 articles were chosen for the quality check. Fourteen medium to high-quality papers were chosen out of the 18 publications to be included in the study design. The reviewed literature showed no significant utility of ctDNA in detecting early-stage tumors of size less than 1 cm diameter. Still, the ideal screening test would require the assay to detect a size <5 mm tumor, which is nearly impossible with the current data. The sensitivity and specificity of the assay ranged from 69% to 98% and 99%, respectively. Furthermore, CancerSEEK achieves tumor origin localization in 83% of cases, while targeted error correction sequencing (TEC-Seq) assays demonstrate a cancer detection rate ranging from 59% to 71%, depending on the type of cancer. However, it could be of great value as a prognostic indicator, and the levels are associated with progression-free survival (PFS) and overall survival (OS) rates, wherein the positive detection of ctDNA is associated with worse OS compared to the tumors detected through standard procedures, with an odds ratio (OS) of 4.83. We conclude that ctDNA could be better applied in cancer patients for prognosis, disease progression monitoring, and treatment outcomes compared to its use in early cancer detection. Due to its specific feature of recognizing the tumor-related mutations, it could be implemented as a supplemental tool to assess the nature of the tumor, grade, and size of the tumor and for predicting the outcomes by pre-operative and post-operative evaluation of the tumor marker, ctDNA, and thereby estimating PFS and OS depending on the level of marker present. A vast amount of research is required in early detection to determine the sensitivity, specificity, false positive rates, and false negative rates in evaluating its true potential as a screening tool. Even if the test could detect the mutations, an extensive workup for the search of tumor is required as the assay could only detect but cannot localize the disease. Establishing the clinical validity and utility of ctDNA is imperative for its implementation in future clinical practice.

The quality of German - language patient decision aids for oncological patients on the internet.

BACKGROUND: Previous studies have already shown that decision aids are a suitable tool for patient decision-making. The aim of this work is to conduct an online search for freely available, German-language patient decision aids (PDAs) for cancer patients, followed by an assessment of their quality. For this purpose, a rating tool that is as manageable as possible was developed on the basis of already existing quality criteria. METHODS: A simulated patient online search was conducted via the four most frequently used search engines in Germany. A quality assessment tool was created utilizing international and national guidelines, with a focus on practicality and manageability. Subsequently, the identified PDAs were rated by 4 raters based on the rating tool. RESULTS: The number of German-language oncology PDAs is low (n = 22 of 200 URLs) with limited variability regarding rare cancers. Most originate from non-profit organizations. The overall quality is low, as indicated by an average of 57.52% of the maximum evaluation points of the developed quality assessment tool. Reference values used to assess quality were related to e.g. support/effectiveness, adaptation, layout, etc. No qualitative differences were found regarding different publishers. Quality differed between PDAs of different length, with longer PDAs achieving better results. CONCLUSION: Overall, the supply and quality of German-language PDAs is not satisfactory. The assessment tool created in this study provides a solid, but more manageable basis, for developing and identifying high-quality PDAs. PRACTICE IMPLICATIONS: PDAs should be increasingly used by physicians in practice. For this, a quick qualitative assessment of PDAs in everyday life must be possible. Future research has to investigate especially the aspect of the length of a PDA in more detail.

Attitudes and Factors Determining the Practice of Routine Medical Checkups in the People of Rawalpindi, Pakistan: A Cross-Sectional Study.

INTRODUCTION: Routine medical checkup (RMC) is a screening and preventive technique that is implied to detect non-communicable diseases (NCDs). This study aims to assess the awareness in public regarding RMC, the association between education level and level of familiarity regarding RMC, and factors that prevent and encourage the practice of RMC by the public. METHODS: This is a cross-sectional study carried out in Rawalpindi, Pakistan. Health professionals and individuals who refused to consent were excluded from the study. Data was collected using a mixed-mode questionnaire, and convenient sampling was used. The sample size was calculated to be 355 according to the WHO sample size calculator. A total of 356 individuals participated in this study after giving informed consent. Both male and female adults aged 18 or older and residents of Rawalpindi were included in the study. Individuals younger than 18 were excluded.  Results: Among the 356 study participants, 160 (45%) were males, and 196 (55%) were females. The mean age was 27.57±10.027. Among the total participants, 33 (9.3%) individuals had primary-level education, 100 (28.1%) individuals had secondary-level education, and 233 (62.6%) had graduate-level education. A total of 329 (92.9%) participants knew that RMCs could help in early diagnosis and treatment. On the contrary, only 154 (43.3%) people knew that RMCs involve screening all body tissues. Only 329 (92.4%) participants said that they were aware that timely diagnosis through RMC can lead to early treatment. Graduates were generally more aware of different aspects of RMCs, especially in the domains of awareness regarding what an RMC is and that RMC can help in timely diagnosis compared to participants who had primary or secondary level of education (p<0.001). Females had a greater overall awareness of RMCs than males (p<0.001). Graduates were more likely to undergo RMCs than people educated till the primary or secondary level (p<0.001). The most common reason for undergoing RMC was "just concerned about health," which was selected by 130 (36.5%) participants. The most common reason mentioned by participants for not having an RMC was ''heavy cost,'' mentioned by 104 (29.2%) participants.  Conclusion: Most of the participants of this study were well educated and were students in terms of profession. The majority of the study population knew that RMCs could help in early diagnosis and treatment. Awareness regarding RMCs was linked to educational level. Females had overall better knowledge regarding RMCs than men. The most common reported reason to have an RMC was a health concern, and the most common reported reason for not having an RMC was its high cost.

Contemporary Practices for Medical Evaluation of the Psychiatric Patient in the Emergency Department.

Although emergency department (ED) visits for patients with mental illness are frequent, medical evaluation (i.e., "medical screening") of patients presenting with psychiatric complaints is inconsistent. This may largely be related to differing goals for medical screening, which often vary according to specialty. Although emergency physicians typically focus on stabilization of life-threatening diseases, psychiatrists tend to believe that care in the ED is more comprehensive, which often places the two fields at odds. The authors discuss the concept of medical screening, review the literature on this topic, and offer a clinically oriented update to the 2017 American Association for Emergency Psychiatry consensus guidelines on medical evaluation of the adult psychiatric patient in the ED.

Questioning 'Informed Choice' in Medical Screening: The Role of Neoliberal Rhetoric, Culture, and Social Context.

Participation in medical screening programs is presented as a voluntary decision that should be based on an informed choice. An informed choice is often emphasized to rely on three assumptions: (1) the decision-maker has available information about the benefits and harms, (2) the decision-maker can understand and interpret this information, and (3) the decision-maker can relate this information to personal values and preferences. In this article, we empirically challenge the concept of informed choice in the context of medical screening. We use document analysis to analyze and build upon findings and interpretations from previously published articles on participation in screening. We find that citizens do not receive neutral or balanced information about benefits and harms, yet are exposed to manipulative framing effects. The citizens have high expectations about the benefits of screening, and therefore experience cognitive strains when informed about the harm. We demonstrate that decisions about screening participation are informed by neoliberal arguments of personal responsibility and cultural healthism, and thus cannot be regarded as decisions based on individual values and preferences independently of context. We argue that the concept of informed choice serves as a power technology for people to govern themselves and can be considered an implicit verification of biopower.

Early triage of a patient with metastatic melanoma presenting as mechanical knee pain - a case report.

Physical therapists (PTs) working in primary care settings commonly encounter mechanical causes of knee pain. Non-mechanical causes of knee pain, such as bone tumors, are rare, and therefore, PTs often have a low index of suspicion regarding sinister pathology. The purpose of this case report is to describe the physical therapist's clinical reasoning process for a 33-year-old female presenting with medial knee pain and a subsequent history of metastatic melanoma. Initially, subjective and objective testing pointed to a mechanical internal derangement of the knee. However, symptom progression and poor treatment responses between physical therapy visits 2 and 3 raised suspicions as to the cause of the knee pain. This prompted an orthopedic referral and medical imaging, revealing a large bone tumor invading the medial femoral condyle, which was further characterized as metastatic melanoma by a specialty oncology team. Further imaging revealed several metastatic subcutaneous, intramuscular and cerebral lesions. This case highlights the importance of the ongoing medical screening process, including the monitoring of symptoms and treatment responses.

Clinicians should have a high index of suspicion in patients with a prior cancer diagnosis and unresolving pain without a relevant explanation or injury.The screening process should include active monitoring of treatment responses and appropriate referral for plain radiographs where hypothesized timeframes are exceeded or sinister pathology is suspected.Early specialist referral and subsequent oncology team referral is imperative for bone tumors, to assess metastatic disease and initiate treatment.

Pre-race self-reported medical conditions and allergies in 133 641 Comrades ultramarathon (90km) runners - SAFER XXIII.

OBJECTIVES: To determine the prevalence of self-reported pre-race chronic medical conditions and allergies in ultramarathon race entrants and to explore if these are associated with an increased risk of race-day medical encounters (MEs). METHODS: Data from two voluntary open-ended pre-race medical screening questions (Q1 - history of allergies; Q2 - history of chronic medical conditions/prescription medication use) were collected in 133641 Comrades Marathon race entrants (2014-2019). Race-day ME data collected prospectively over 6 years are reported as incidence (per 1000 starters) and incidence ratios (IR: 95%CI's). RESULTS: Pre-race medical screening questions identified race entrants with a history of chronic medical conditions and/or prescription medication use (6.9%) and allergies (7.4%). The % entrants with risk factors for cardiovascular disease (CVD) was 30% and being older (>45 years) or male (27.5%) were the most frequent CVD risk factors. 0.3% of entrants reported existing CVD. The overall incidence of MEs was 20/1000 race starters. MEs were significantly higher in race entrants reporting a 'yes' to Q1 (allergies) (IR = 1.3; 1.1-1.5) (p = 0.014) or Q2 (chronic medical conditions and/or prescription medication use) (IR = 1.3; 1.1-1.5) (p = 0.0006). CONCLUSIONS: Voluntary completion of two open-ended questions identified chronic medical conditions and/or prescription medication use in 6.9% and allergies in 7.4% of ultramarathon race entrants. This is lower than that reported for other races that implemented compulsory completion of a more comprehensive pre-screening questionnaire. Despite potential under-reporting, a pre-race self-reported history of chronic medical conditions and allergies was associated with a higher risk of race-day MEs.

Waiting for medical test results: A delay discounting approach.

RATIONALE AND OBJECTIVE: Delay discounting is the devaluation of an outcome as a function of delay until receiving that outcome. In two studies, we used a delay discounting approach to examine how wait times for a medical diagnosis can affect people's decision to undergo medical testing. METHODS: In Study 1 (N = 151), participants rated the likelihood they would get tested for a severe and a mild disease with wait times ranging from 0 to 180 days (within persons). Study 2 (N = 400) randomized disease severity (severe vs. mild) between persons and manipulated disease curability (curable vs. incurable). RESULTS: Likelihood of testing decreased as delay until receiving test results increased. This effect of delay on testing was stronger for the mild than for the severe disease, and for the curable than for the incurable disease. CONCLUSIONS: We found strong evidence for a delay discounting effect, an effect that varied depending on aspects of diseases. The findings illustrate how delay discounting can affect screening uptake and how it is moderated by disease characteristics.

Chlamydia trachomatis as a Current Health Problem: Challenges and Opportunities.

Chlamydia is one of the most common sexually transmitted bacterial infections (STIs) worldwide. It is caused by Chlamydia trachomatis (CT), which is an obligate intracellular bacterium. In some cases, it can occur in coinfection with other parasites, increasing the pathologic potential of the infection. The treatment is based on antibiotic prescription; notwithstanding, the infection is mostly asymptomatic, which increases the risk of transmission. Therefore, some countries have implemented Chlamydia Screening Programs in order to detect undiagnosed infections. However, in Portugal, there is no CT screening plan within the National Health Service. There is no awareness in the general healthcare about the true magnitude of this issue because most of the methods used are not Nucleic Acid Amplification Technology-based and, therefore, lack sensitivity, resulting in underreporting infection cases. CT infections are also associated with possible long-term severe injuries. In detail, persistent infection triggers an inflammatory milieu and can be related to severe sequels, such as infertility. This infection could also trigger gynecologic tumors in women, evidencing the urgent need for cost-effective screening programs worldwide in order to detect and treat these individuals adequately. In this review, we have focused on the success of an implemented screening program that has been reported in the literature, the efforts made concerning the vaccine discovery, and what is known regarding CT infection. This review supports the need for further fundamental studies in this area in order to eradicate this infection and we also suggest the implementation of a Chlamydia Screening Program in Portugal.

Automatic Facial Palsy Diagnosis as a Classification Problem Using Regional Information Extracted from a Photograph.

The incapability to move the facial muscles is known as facial palsy, and it affects various abilities of the patient, for example, performing facial expressions. Recently, automatic approaches aiming to diagnose facial palsy using images and machine learning algorithms have emerged, focusing on providing an objective evaluation of the paralysis severity. This research proposes an approach to analyze and assess the lesion severity as a classification problem with three levels: healthy, slight, and strong palsy. The method explores the use of regional information, meaning that only certain areas of the face are of interest. Experiments carrying on multi-class classification tasks are performed using four different classifiers to validate a set of proposed hand-crafted features. After a set of experiments using this methodology on available image databases, great results are revealed (up to 95.61% of correct detection of palsy patients and 95.58% of correct assessment of the severity level). This perspective leads us to believe that the analysis of facial paralysis is possible with partial occlusions if face detection is accomplished and facial features are obtained adequately. The results also show that our methodology is suited to operate with other databases while attaining high performance, even though the image conditions are different and the participants do not perform equivalent facial expressions.

Factors affecting routine medical screening among health workers in a tertiary hospital in Delta State.

Background: Routine medical screening usually involves periodic history taking, physical examination, and laboratory tests on a regular basis for asymptomatic individuals for continuing self-health care. Aim: This study aimed to determine the knowledge, practice, and factors affecting practice of routine medical screening among health workers in Delta State University Teaching Hospital, Oghara. Subjects and Methods: The study population comprised all staff of the hospital. The sample size was determined using the Yamane formula; n = N/1 + N (e) = 295. A structured questionnaire was distributed among the various staff of the hospital that consented to participate in the study by agreeing to complete the questionnaire. Permission for the study was obtained from Ethics committee of the hospital. Data analysis was by SPSS version 22 (IBM). Results: About 297 participants completed their questionnaires. Female respondents (53.20%) participated more than males (46.80%). Nurses made up 25.5%, 18.8% were doctors, and 16.4% were administrative staff. Among the respondents, knowledge score was good in 58.3%, fair in 25.1%, and poor in 25.1%. The perception score among the respondents was good in 187 and poor in 110. The main reasons for not doing routine medical screening in the last one year were attributed to cost of tests (36.4%). The main reasons for doing a medical test in the past one year were mainly because of illness (60.0%). The practice of routine medical screening score was good in (26.2%) and poor in (73.7%). There was statistically significant association between sex and practice of routine medical screening, females had better practice of routine medical screening compared to men, P = 0.004. The main factors that affected routine medical screening were sex, being managed for a medical condition, and cost of the medical screening. Conclusion: The practice of routine medical screening by the health care workers in our region is poor despite the demonstration of a good knowledge. The major factors affecting uptake of routine medical screening were sex, history of being managed for a health condition, and financial constraint. Staff of the hospital should be better enlightened on the use and importance of the Contributory Health Scheme in routine medical screening.

A new classification system for autism based on machine learning of artificial intelligence.

BACKGROUND: Autistic Spectrum Disorder (ASD) is a neurodevelopment condition that is normally linked with substantial healthcare costs. Typical ASD screening techniques are time consuming, so the early detection of ASD could reduce such costs and help limit the development of the condition. OBJECTIVE: We propose an automated approach to detect autistic traits that replaces the scoring function used in current ASD screening with a more intelligent and less subjective approach. METHODS: The proposed approach employs deep neural networks (DNNs) to detect hidden patterns from previously labelled cases and controls, then applies the knowledge derived to classify the individual being screened. Specificity, sensitivity, and accuracy of the proposed approach are evaluated using ten-fold cross-validation. A comparative analysis has also been conducted to compare the DNNs' performance with other prominent machine learning algorithms. RESULTS: Results indicate that deep learning technologies can be embedded within existing ASD screening to assist the stakeholders in the early identification of ASD traits. CONCLUSION: The proposed system will facilitate access to needed support for the social, physical, and educational well-being of the patient and family by making ASD screening more intelligent and accurate.

Exploring the Ethics of Implementation of Epigenomics Technologies in Cancer Screening: A Focus Group Study.

New epigenomics technologies are being developed and used for the detection and prediction of various types of cancer. By allowing for timely intervention or preventive measures, epigenomics technologies show promise for public health, notably in population screening. In order to assess whether implementation of epigenomics technologies in population screening may be morally acceptable, it is important to understand - in an early stage of development - ethical and societal issues that may arise. We held 3 focus groups with experts in science and technology studies (STS) (n = 13) in the Netherlands, on 3 potential future applications of epigenomic technologies in screening programmes of increasing scope: cervical cancer, female cancers and 'global' cancer. On the basis of these discussions, this paper identifies ethical issues pertinent to epigenomics-based population screening, such as risk communication, trust and public acceptance; personal responsibility, stigmatisation and societal pressure, and data protection and data governance. It also points out how features of epigenomics (eg, modifiability) and changing concepts (eg, of cancer) may challenge the existing evaluative framework for screening programmes. This paper aims to anticipate and prepare for future ethical challenges when epigenomics technologies can be tested and introduced in public health settings.
