Delivering blended bioinformatics training in resource-limited settings: a case study on the University of Khartoum H3ABioNet node.

MOTIVATION: Delivering high-quality distance-based courses in resource-limited settings is a challenging task. Besides the needed infrastructure and expertise, effective delivery of a bioinformatics course could benefit from hands-on sessions, interactivity and problem-based learning approaches. RESULTS: In this article, we discuss the challenges and best practices in delivering bioinformatics training in resource-limited settings taking the example of hosting and running a multiple-delivery online course, Introduction to Bioinformatics, that was developed by the H3ABioNet Education and Training working group and delivered in 27 remote classrooms across Africa in 2017. We take the case of the University of Khartoum classrooms. Believing that our local setting is similar to others in less-developed countries, we also reflect upon aspects like classroom environment and recruitment of students to maximize outcomes.

Effect of TAVR Approach and Other Baseline Factors on the Incidence of Acute Kidney Injury: A Systematic Review and Meta-Analysis.

Background: Acute kidney injury (AKI) is a well-known complication following a transcatheter aortic valve replacement (TAVR) and is associated with higher morbidity and mortality. Objective: We aim to compare the risk of developing AKI after transfemoral (TF), transapical (TA), and transaortic (TAo) approaches following TAVR. Methods: We searched Medline and EMBASE databases from January 2009 to January 2021. We included studies that evaluated the risk of AKI based on different TAVR approaches. After extracting each study's data, we calculated the risk ratio and 95% confidence intervals using RevMan software 5.4. Publication bias was assessed by the forest plot. Results: Thirty-six (36) studies, consisting of 70,406 patients undergoing TAVR were included. Thirty-five studies compared TF to TA, and only seven investigations compared TF to TAo. AKI was documented in 4,857 out of 50,395 (9.6%) patients that underwent TF TAVR compared to 3,155 out of 19,721 (16%) patients who underwent TA-TAVR, with a risk ratio of 0.49 (95% CI, 0.36-0.66; p < 0.00001). Likewise, 273 patients developed AKI out of the 1,840 patients (14.8%) that underwent TF-TAVR in contrast to 67 patients out of the 421 patients (15.9%) that underwent TAo-TAVR, with a risk ratio of 0.51 (95% CI, 0.27-0.98; p = 0.04). There was no significant risk when we compared TA to TAo approaches, with a risk ratio of 0.89 (95% CI, 0.29-2.75; p = 0.84). Conclusion: The risk of post-TAVR AKI is significantly lower in patients who underwent TF-TAVR than those who underwent TA-TAVR or TAo-TAVR.

Best shot: A motivational interviewing approach to address vaccine hesitancy in pediatric outpatient settings.

BACKGROUND: Vaccine hesitancy in parents and childhood vaccine refusal is increasing. A standard of care to address this problem has not been identified. PURPOSE: To identify if the use of motivational interviewing by pediatric providers during routine well child visits, when compared to standard of care, would increase vaccine rates in children 0-12 months of age. Factors associated with vaccine hesitancy were also investigated. METHODS: A quasi-experimental study was completed on a convenience sample of pediatric providers (N = 6) and caregivers of children 0-12 months of age (N = 66). Four providers were trained to use motivational interviewing. During the well child visit the Parent Attitudes About Childhood Vaccines survey was completed, and the motivational interviewing intervention was implemented. Clinic's data were compared with other clinic data of non-trained providers. FINDINGS: Vaccine refusal/delays rate was 11.4% among caregivers. Vaccine refusal rate decreased after the intervention (9.00% pre-intervention and 6.40% post-intervention). An ordinal regression identified caregivers with higher vaccine hesitancy scores and more children were more likely to delay or refuse vaccines, while caregivers ≥30 years or with high income were less likely to delay/refuse vaccines. A difference in difference analysis identified that an additional 2.6% of children received vaccines when seen by trained providers compared to non-trained (ß = -0.330, OR = 0.719, p = 0.470). DISCUSSION: Findings indicate a condensed motivational interviewing education session may be clinically significant in decreasing vaccine hesitancy among this population. APPLICATIONS TO PRACTICE: A more robust study to confirm these findings is recommended prior to practice implementation.

Curcumin mouthwashes versus chlorhexidine in controlling plaque and gingivitis: A systematic review and meta-analysis.

OBJECTIVES: The purpose of the present systematic review and meta-analysis was to assess the available evidence regarding the efficacy of curcumin mouthwashes on plaque and gingivitis. METHODS: A comprehensive online search of multiple databases (PubMed, Scopus, Web of Science, and Google Scholar) was performed to identify all relevant studies published up to August 2020, using the following keywords: curcumin, turmeric, gingivitis, periodontal health, and plaque control. All clinical trials that compared the efficacy of curcumin mouthwash with chlorhexidine in controlling dental plaque and gingivitis were included. Data were analysed using Review Manager (RevMan) 5.3 software. The risk of bias was evaluated by two independent reviewers using the Cochrane assessment tool. RESULTS: Six randomized clinical trials (comprising 320 subjects) fulfilled the eligibility criteria. Five studies showed a high risk of bias and only one study showed a low risk of bias. The pooled data of the six included studies revealed comparable efficacy of curcumin and chlorhexidine in reducing dental plaque (I2  = 91%; standardized mean difference [SMD]: 0.27, 95% CI: -0.53, 1.07, p = 0. 51) and gingival inflammation (I2  = 40%; SMD: -0.13, 95% CI: -0.35, 0.09, p = 0.24), with no statistically significant differences between the two groups. CONCLUSION: The results suggest that curcumin mouthwashes have promising anti-plaque and anti-gingivitis properties. Further clinical trials with adequate sample sizes and standardized methodologies are required to discern the efficacy of curcumin mouthwash in reducing plaque and gingivitis.

A crowdsourced set of curated structural variants for the human genome.

A high quality benchmark for small variants encompassing 88 to 90% of the reference genome has been developed for seven Genome in a Bottle (GIAB) reference samples. However a reliable benchmark for large indels and structural variants (SVs) is more challenging. In this study, we manually curated 1235 SVs, which can ultimately be used to evaluate SV callers or train machine learning models. We developed a crowdsourcing app-SVCurator-to help GIAB curators manually review large indels and SVs within the human genome, and report their genotype and size accuracy. SVCurator displays images from short, long, and linked read sequencing data from the GIAB Ashkenazi Jewish Trio son [NIST RM 8391/HG002]. We asked curators to assign labels describing SV type (deletion or insertion), size accuracy, and genotype for 1235 putative insertions and deletions sampled from different size bins between 20 and 892,149 bp. 'Expert' curators were 93% concordant with each other, and 37 of the 61 curators had at least 78% concordance with a set of 'expert' curators. The curators were least concordant for complex SVs and SVs that had inaccurate breakpoints or size predictions. After filtering events with low concordance among curators, we produced high confidence labels for 935 events. The SVCurator crowdsourced labels were 94.5% concordant with the heuristic-based draft benchmark SV callset from GIAB. We found that curators can successfully evaluate putative SVs when given evidence from multiple sequencing technologies.

Improving Postpartum Depression Screening in Pediatric Primary Care: A Quality Improvement Project.

BACKGROUND: Despite recommendations for standardized postpartum depression screening in primary care pediatrics, few pediatric healthcare providers are adequately screening mothers for postpartum depression. AIMS: To improve standardized screening for postpartum depression in the pediatric primary care setting. Secondary aims were to determine if infant and family characteristics (gender of infant, feeding method, insurance type, income level, ethnicity of infant) were associated with positive postpartum depression screening. METHODS: This quality improvement project involved implementing a standardized postpartum depression screening tool into pediatric primary care practice. Independent samples t-test and logistic regression were used for data analysis. RESULTS: Postpartum depression screening practices improved from 83% to 88% (p = 0.096). Although not statistically significant, infant characteristics of male gender, Medicaid or sliding-scale payment for services, and Hispanic ethnicity were associated with higher rates of positive postpartum depression screens. CONCLUSIONS: Pediatric health care providers can effectively screen for postpartum depression. Certain infant and family characteristics may alert the provider to higher risks for mothers.

Developing reproducible bioinformatics analysis workflows for heterogeneous computing environments to support African genomics.

BACKGROUND: The Pan-African bioinformatics network, H3ABioNet, comprises 27 research institutions in 17 African countries. H3ABioNet is part of the Human Health and Heredity in Africa program (H3Africa), an African-led research consortium funded by the US National Institutes of Health and the UK Wellcome Trust, aimed at using genomics to study and improve the health of Africans. A key role of H3ABioNet is to support H3Africa projects by building bioinformatics infrastructure such as portable and reproducible bioinformatics workflows for use on heterogeneous African computing environments. Processing and analysis of genomic data is an example of a big data application requiring complex interdependent data analysis workflows. Such bioinformatics workflows take the primary and secondary input data through several computationally-intensive processing steps using different software packages, where some of the outputs form inputs for other steps. Implementing scalable, reproducible, portable and easy-to-use workflows is particularly challenging. RESULTS: H3ABioNet has built four workflows to support (1) the calling of variants from high-throughput sequencing data; (2) the analysis of microbial populations from 16S rDNA sequence data; (3) genotyping and genome-wide association studies; and (4) single nucleotide polymorphism imputation. A week-long hackathon was organized in August 2016 with participants from six African bioinformatics groups, and US and European collaborators. Two of the workflows are built using the Common Workflow Language framework (CWL) and two using Nextflow. All the workflows are containerized for improved portability and reproducibility using Docker, and are publicly available for use by members of the H3Africa consortium and the international research community. CONCLUSION: The H3ABioNet workflows have been implemented in view of offering ease of use for the end user and high levels of reproducibility and portability, all while following modern state of the art bioinformatics data processing protocols. The H3ABioNet workflows will service the H3Africa consortium projects and are currently in use. All four workflows are also publicly available for research scientists worldwide to use and adapt for their respective needs. The H3ABioNet workflows will help develop bioinformatics capacity and assist genomics research within Africa and serve to increase the scientific output of H3Africa and its Pan-African Bioinformatics Network.

Serum cathelicidin as a marker for diabetic nephropathy in patients with type 1 diabetes.

BACKGROUND: The aim of the study was to evaluate the relationship between serum cathelicidin level and diabetic nephropathy (DN) in patients with type 1 diabetes mellitus (T1DM). METHODS: The study group consisted of 76 patients with T1DM (47 men), aged 36 ± 7 years, and with duration of T1DM 14 (7-18) years. Serum cathelicidin was measured by ELISA test in healthy controls (n = 20) and in 76 T1DM patients grouped as follows: G1 = patients with normal urinary albumin excretion (n = 20), G2 = patients with microalbumin excretion (n = 19), G3 = patients with macroalbumin excretion but normal serum creatinine level (n = 19), and G4 = patients with macroalbumin excretion with increased serum creatinine (n = 18). RESULTS: There was no significant difference in serum cathelicidin levels between healthy controls and G1 diabetic patients, but serum levels were progressively increased from the stage of microalbuminuria to frank nephropathy (P < .001). Positive correlation between serum cathelicidin level and the presence of DN, thyroid-stimulating hormone, total cholesterol, and negative with male sex and fasting plasma glucose, was found. In multiple regression analysis, serum cathelicidin level was associated with the presence of DN after adjustment of sex, waist-to-hip ratio, total cholesterol, and thyroid-stimulating hormone. CONCLUSIONS: Patients with T1DM and DN are characterized by increased serum cathelicidin level. There was an independent relationship between serum cathelicidin level and DN. Serum cathelicidin level can be used as an early marker for the presence and progression of DN in T1DM patients.

Association between changes in the intrathoracic impedance and ventricular arrhythmias in patients with heart failure.

BACKGROUND: Ventricular arrhythmias (VAs) are independently related to mortality risk in patients with heart failure (HF). The wide availability of implantable cardioverter defibrillators and cardiac resynchronization therapy devices now offers an opportunity to clinically correlate the two disease processes. We hypothesized that there is an association between changes in the intrathoracic impedance and episodes of VA. METHODS: Nonconcurrent prospective study of adults (age >20 years) with known HF with reduced ejection fraction (<35%). The OptiVol threshold was categorized as follows: 0-30 Ω-days, 31-60 Ω-days, 61-90 Ω-days, 91-120 Ω-days, and >120 Ω-days. Patients with OptiVol values at 0-30 Ω-days were used as the reference group. Receiver operating characteristic analysis was used to estimate the sensitivity and specificity at each threshold. RESULTS: Of the 87 eligible patients, 65.5% were males. The mean age of the sample was 73.3 years (±12.7). Compared to patients in the 0-30 Ω-days category, those in the 31-60, 61-90, 91-120, and >120 Ω-days groups had, on average, 1.48, 1.64, 2.24, and 1.6 more VAs, respectively (P = 0.002, 0.009, 0.010 and 0.009, respectively). The sensitivity and specificity of each threshold were as follows: 82.6% and 61.7% at 31-60 Ω-days, 43.5% and 78.3% at 61-90 Ω-days, 30.4% and 85.0% at 91-120 Ω-days, and 21.7% and 88.3% at >121 Ω-days. CONCLUSION: Our study found a significant positive relationship between changes in intrathoracic impedance and episodes of VAs in patients with HF.

The Effect of Concept Maps on Undergraduate Nursing Students' Critical Thinking.

AIM: The aim of the study was to evaluate the effect of using concept maps as a teaching and learning strategy on students' critical thinking abilities and examine students' perceptions toward concept maps utilizing the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. BACKGROUND: Researchers have found that almost two thirds of nurse graduates do not have adequate critical thinking skills for a beginner nurse. Critical thinking skills are required for safe practice and mandated by accrediting organizations. Nursing educators should consider teaching and learning strategies that promote the development of critical thinking skills. METHOD: A literature review was conducted using "concept maps, nursing education, and critical thinking" as the combined search terms. Inclusion criteria were studies that measured the effects of concept mapping on critical thinking in nursing students. RESULTS: Seventeen articles were identified. CONCLUSION: Concept maps may be useful tools to promote critical thinking in nursing education and for applying theory to practice.

Factors Associated with Parental Compliance with Supine Infant Sleep: An Integrative Review.

Despite educational programs, sudden infant death syndrome (SIDS) rates remain unacceptably high, especially among low-income and African-American populations. The purpose of this review is to examine reasons for parental noncompliance with supine sleep recommendations. A database search in Cochrane Database of Systematic Reviews, PubMed, EBSCOhost, and CINAHL was conducted using keywords SIDS, prevention and control, parental compliance, nursing, supine position, Back to Sleep campaign, and Safe to Sleep campaign. Literature was included from 2002 to 2014. Types of studies included randomized control trials, literature reviews, and descriptive studies. Literature from academic journals was also included. Included literature discussed parental knowledge, the Back to Sleep and the Safe to Sleep campaigns, compliance with recommendations from the American Academy of Pediatrics (AAP), and interventions and education. Seventeen studies were included that used data collection methods, including surveys, focus groups, face-to-face interviews, and questionnaires. Major trends identified as being associated with noncompliance included parent knowledge, sources of advice, infant comfort and quality of infant sleep, safety concerns (i.e., choking), race/ethnicity, education level, and income. Noncompliance was highest among single, less-educated, low-income, or African-American parents.

Managing Ulcerative Colitis in the Adolescent: Highlighting the Developmental and Self-management Needs.

Ulcerative colitis (UC) is a lifelong disease that peaks in diagnosis between the ages of 15 to 25 years, making UC a significant chronic disease among adolescents that could affect the adolescents throughout their life. This article provides an overview of the role of nurse practitioners as health care providers in managing adolescent patients with UC with a holistic approach that encompasses the physical aspects of the disease, as well as developmental and psychosocial needs. By describing the influence that developmental stage and psychological stress have on patients with UC, the nurse practitioners can facilitate evidence-based and holistic care for adolescents and promote self-management.

Seropositivity of Toxoplasmosis in Pregnant Women by ELISA at Minia University Hospital, Egypt.

Toxoplasmosis is considered as an important risk factor for bad obstetric history (BOH) and one of the major causes of congenitally acquired infections. The present study aimed to estimate the seropositivity of T. gondii infection and associated risk factors among the attendees of high risk pregnancy and low risk antenatal care clinic of Minia Maternity and Pediatric University Hospital, Minia, Egypt. The study was carried out from April 2013 to April 2014 through 2 phases, the first phase was case-control study, and the second phase was follow-up with intervention. A total of 120 high risk pregnant and 120 normal pregnant females were submitted to clinical examinations, serological screening for anti-Toxoplasma IgM and IgG antibodies by ELISA, and an interview questionnaire. Seropositive cases were subjected to spiramycin course treatment. The results showed that the seroprevalence of toxoplasmosis in high-risk pregnancy group was 50.8%, which was significantly different from that of normal pregnancy group (P<0.05). Analysis of seropositive women in relation to BOH showed that abortion was the commonest form of the pregnancy wastage (56.5%). The high prevalence of T. gondii seropositive cases was observed in the age group of 21-30 years. Post-delivery adverse outcome was observed in 80.3% of high-risk pregnancy group compared to 20% of normal pregnancy group. There was a statistically significant relationship between seropositivity and living in rural area, low socioeconomic level, and undercooked meat consumption (P<0.05). Serological screening for anti-Toxoplasma antibodies should be routine tests especially among high-risk pregnant women.

Impact of telemedicine in managing type 1 diabetes among school-age children and adolescents: an integrative review.

Patients with diabetes who have limited access to healthcare services are less likely to maintain adequate diabetes control. Telemedicine represents a useful solution to the strict follow up required in diabetes management. This review analyzes the impact that telemedicine has on the management of type 1 diabetes among school-age children and adolescents, as measured by compliance with blood glucose monitoring, glycemic control, satisfaction, and self management. In general, this review supports the use of telemedicine in maintaining glycemic control. Further studies are desired to observe the impact of telemedicine in managing type 1 diabetes in school-age children and adolescents.

Impact of a structured sleep education program on mothers' knowledge and attitudes toward infant sleeping.

Introduction: Sleeping is necessary for the infant growth and development. Sufficient and quality of sleep can have an impact on physical, cognitive, and emotional functioning. Infancy is a critical time for establishing healthy habits and routines. However, many infants were suffering from sleeping issues that impact their health. Objectives: This study aims to evaluate the effect of educational programs given to mothers regarding their infants' sleep on mothers' knowledge and attitudes toward infant's sleeping. Method: A quasi-experimental design for nonequivalent groups was used, and data was collected from 208 mothers with infants aged 5-12 months from all Jordanian governorates who had not been exposed to educational programs prior to this study. Data was collected in two stages: pre-test and post-test, with two weeks in between for both groups. Results: The final results indicated that the educational intervention had a significant impact on mothers' knowledge over time. It was found that mothers in the intervention group had significantly higher mean of infant sleep health knowledge at follow up time compared to their baseline time (B = 0.236, P 0.001). Also, the yielded analysis showed that there was no significant change in mothers' mean attitudes toward infants sleeping over time (P = 0.011). The mothers' measured sleep health knowledge correlated positively and significantly statistically with their sleep health attitudes score (r = 0.436, P 0.010).

The Potential Association Between microRNA 135-5P and p62 and Their Effect on NRF2 Pathway in Multiple Sclerosis.

Background: Multiple Sclerosis (MS) is a prevalent non-traumatic disabling disease affecting young adults, characterized by complexity in its pathogenesis. Nuclear factor erythroid 2-Related Factor 2 (NRF2) serves as a crucial transcriptional regulator of anti-inflammatory and antioxidant enzymes, influenced by the ubiquitous protein p62. It acts as a scaffold directing substrates to autophagosomes. This study aims to explore the potential association between microRNA 135-5p and p62 and their impact on inflammation and oxidative stress through the NRF2 pathway in MS. Methods: The study included 30 healthy controls and 60 MS patients (relapsing-remitting and secondary progressive). Real-time PCR was employed for the detection of Nrf2, p62, miRNA135-5P, and NF-κB in serum, while p53 levels were determined using ELISA. Results: Nrf2 and p62 expression was significantly downregulated in the MS group compared to controls. Conversely, miRNA135-5P, NF-κB expression, and P53 levels were significantly elevated in the MS group. Conclusions: This study reveals a potential association between miRNA 135-5p and p62, indicating their role in the pathogenesis of MS. Results suggest that miRNA 135-5p and p62 may influence inflammation and oxidative stress in MS through the NRF2 pathway, potentially mediated by NF-κB and p53.

Serum selenium status in Egyptians patients who had Graves' disease with and without ophthalmopathy.

Selenium is efficient in reducing the progression of active Graves' orbitopathy and improving life quality. The impact of mending relative deficiency of selenium on improving Graves' orbitopathy is not known, due to the lack of previous measurement of baseline levels of selenium. The study object was to determine whether serum selenium levels are lower in patients with Graves' ophthalmopathy (GO) disease in comparison with those without ophthalmopathy. This prospective case control study was conducted between 2019 and 2021 at the endocrine and ophthalmology clinics, Ain Shams University, Cairo. The study included a total of 75 subjects, 50 patients with Graves' disease (GD) and 25 subjects as a control group. Of the GD patients, 25 had Graves' orbitopathy. Serum selenium concentrations were measured in each group. The mean level of serum selenium was significantly lower in patients with Graves' orbitopathy (16.6 ± 7.5 ng/ml) than in patients with Graves' disease (42.9 ± 8.2 ng/ml) (p < 0.001). Mean selenium levels were reduced with increasing severity of GO, as selenium level was 30-55 ng/ml in GD, 21-28 ng/ml in mild GO, 18-22 ng/ml in moderate GO and 5-16 ng/ml in severe GO (p < 0.001). In conclusion, serum selenium levels were lower in GO patients compared with GD patients in an Egyptian population. Low selenium levels may be a risk factor for ophthalmopathy in Graves' disease patients.

Calf rEF: Impact of Calf Muscle Pump Dysfunction With Reduced Ejection Fraction on All-Cause Mortality.

OBJECTIVE: To evaluate mortality outcomes by varying degrees of reduced calf muscle pump (CMP) ejection fraction (EF). PATIENTS AND METHODS: Consecutive adult patients who underwent venous air plethysmography testing at the Mayo Clinic Gonda Vascular Laboratory (January 1, 2012, through December 31, 2022) were divided into groups based on CMP EF for the assessment of all-cause mortality. Other venous physiology included measures of valvular incompetence and clinical venous disease (CEAP [clinical presentation, etiology, anatomy, and pathophysiology] score). Mortality rates were calculated using the Kaplan-Meier method. RESULTS: During the study, 5913 patients met the inclusion criteria. During 2.84-year median follow-up, there were 431 deaths. Mortality rates increased with decreasing CMP EF. Compared with EF of 50% or higher, the hazard ratios (95% CIs) for mortality were as follows: EF of 40% to 49%, 1.4 (1.0 to 2.0); EF of 30% to 39%, 1.6 (1.2 to 2.4); EF of 20% to 29%, 1.7 (1.2 to 2.4); EF of 10% to 19%, 2.4 (1.7 to 3.3) (log-rank P≤.001). Although measures of venous valvular incompetence did not independently predict outcomes, venous disease severity assessed by CEAP score was predictive. After adjusting for several clinical covariates, both CMP EF and clinical venous disease severity assessed by CEAP score remained independent predictors of mortality. CONCLUSION: Mortality rates are higher in patients with reduced CMP EF and seem to increase with each 10% decrement in CMP EF. The mortality mechanism does not seem to be impacted by venous valvular incompetence and may represent variables intrinsic to muscular physiology.

Circulating miR-199a and long noncoding-RNA ANRIL as Promising Diagnostic Biomarkers for Inflammatory Bowel Disease.

BACKGROUND & AIMS: Inflammatory bowel disease (IBD), involving both Crohn's disease (CD) and ulcerative colitis (UC), represents a chronic, immune-mediated inflammatory disease due to an uncontrolled, ongoing inflammatory response to intestinal bacteria in those with genetic susceptibility. MicroRNA (miRNA) extrusion from relevant remote organs or tissues is reflected in the expression of miRNAs in serum and plasma. Both UC and CD patients had higher blood levels of expressed miR-199a. Long noncoding RNA (lncRNA) ANRIL is a proinflammatory gene that mediates nuclear factor κB to play a role in inflammatory diseases, such as IBD. The aim of the current study is to investigate the potential role of both miR-199a and ANRIL in diagnosing IBD in adult patients. METHODS: Sixty-seven IBD patients diagnosed clinically, radiologically, endoscopically, and histologically were included in this prospective cohort study. Participants were classified into 3 groups: the UC group (n = 35), the CD group (n = 32), and the control group (n = 30). Demographics, history taking, laboratory characteristics, and treatments were recorded. Tumor necrosis factor α , miR-199a, and ANRIL were measured. RESULTS: The findings suggested that miR-199a and ANRIL might be associated with the occurrence or progression of IBD because both genes were substantially expressed in the peripheral blood of patients with this condition. Receiver-operating characteristic curve analysis indicated that the detection of miR-199a and ANRIL had a predictive sensitivity of 62.9% and 88.6% and a specificity of 70.7% and 96.7% for the occurrence of UC cases, respectively, and a predictive sensitivity of 72.4% and 46.9% and a specificity of 96.7% and 34.7% for the occurrence of CD cases, respectively. CONCLUSIONS: Both miR-199a and ANRIL are abundant in the sera of IBD adult Egyptian patients (UC and CD). Both can represent a noninvasive marker for early disease diagnosis.

This study investigated the relation between tumor necrosis factor α, ANRIL, and miR-199a in inflammatory bowel disease patients to determine the probability of using them as prognostic and diagnostic biomarkers, as well as distinguishing between Crohn's disease and ulcerative colitis patients. Our findings showed that ANRIL and miR-199a can represent noninvasive biomarkers for early disease diagnosis.
