Authors: Al-Saffar Hilal B. , Yassin Adel J. , Ali Ala 
Published: March 2023

Background: Exposure to Contrast media is the third leading cause of hospital acquired acute kidney injury. It follows a predictable time of onset and a less predictable scenario in recovery. This is related to certain factors, but at the end there will be asubstantial association with increased mortality, morbidity, and length of hospitalization.Objectives: To define the Incidence of persistent contrast induced renal impairment a month after angiography and to define the risk factors for such persistencePatients and Methods: One hundred and one patients (101) were enrolled in this study. All were referred to the Iraqi Center for Heart Diseases in Baghdad/ Iraq for coronary and/or peripheral vascular angiography from October 2009 to July 2010. All patients’ clinical and laboratory data including baseline renal function tests were ordered and recorded with subsequent risk categorization. Post procedure serum creatinine checked on regular intervals (48 hours, one week, and then weekly for three months for those with serum creatinine consistent with the contrast induced - acute kidney injury (CI-AKI) definition at 48 hours.Results: The mean age for the study group was 62±16.9 with 78 (77%) male. Twenty three patients (22.7%) had diabetes mellitus. Thirteen patients (12.7%)had a pre-existing renal impairment. Twenty one patients (20.7%) received extradoses of contrast. Thirty two patients (31.6%) developed CIN by the definition within 48 hours of the procedure with the mean serum creatinine of 1.8 mg/dl. Seven patients (6.8%) continued to have impaired renal function at week 4 and persisted to have such low GFR up to three months of the procedure. Baseline low GFR, Diabetes mellitus and extradoses of contrast were independent risk factors for the occurrence of CIN and delayed renal recovery.Conclusion: The risk of poor renal recovery after contrast cannot be overlooked. Preexisting renal function impairment, diabetes mellitus, and extra doses of contrast media are independent risk factors for such delay.
Аlternative local stratigraphical scales of the Upper Miocene of the Rostov Dome
Authors: Ruban D. A. 
Published: March 2023

Background. Definition of local stratigraphical units, the main of which are formations, is important for geological mapping and correct understanding of the composition of sedimentary complexes. This task is yet to be solved for some territories. Thus, Upper Miocene deposits extend widely across the Rostov Dome in the southwest of Russia; however, the definition of formations there is still in its nascent phase.Aim. Systematization of ideas about the local stratigraphical units of the Upper Miocene of the Rostov Dome, taking previous assumptions into account.Materials and methods. An analysis of ideas related to the definition of formations in the Upper Miocene of the Rostov Dome was carried out. These ideas were systematized with a focus on the validity of the units based on the current stratigraphical code.Results. An improved local stratigraphical scale of the Upper Miocene of the Rostov Dome is proposed. This scale implies defining the Taganrogskaya (Lower Sarmatian), Rostovskaya (Middle–Upper Sarmatian), Donskaya (lower Upper Maeotian), Merzhanovskaya (upper Upper Maeotian), and Aleksandrovskaya (Lower Pontian) formations. The correspondence of alternative units is shown: the Mokrochaltyrskaya and Berdanosovskaya formations correspond to the Rostovskaya Formation, while and the later proposed Rostovskaya Formation corresponds to the Donskaya and Merzhanovskaya formations. Discussion. The validity of the proposed local stratigraphical units is noted; the priority of defining the Taganrogskaya and Aleksandrovskaya formations is highlighted. The question of creating an automatic system for generalizing information about stratigraphical units is discussed.Conclusion. The need in the parallel existence of alternative local stratigraphical scales of the Upper Miocene of the Rostov Dome is absent. However, subdividing the relevant deposits requires further discussion and refinement.

Introduction: Down syndrome is the most common congenital chromosomal disorder. In terms of genetic causes of mental impairment, this condition is the most prevalent. The typical characteristics of students with intellectual disability, such as down syndrome are limited attention span and motor skills. Attention is the first stage in information processing. It collects parts of the environmental information for later processing. However, there are dearth of studies which compares attention span of down syndrome children with healthy children of same age group.
Aim: The aim of the study is to examine the attention span of down syndrome children and comparing their attention span with healthy children of same age group.
Materials and methods: The present study had a cross-sectional comparative research design. 20 subjects were taken conveniently which included 10 down syndrome and 10 healthy children (8-14 years old). The attention span was measured by using Stroop color and word test and analyzed with independent t-test.
Results: Independent t-test indicated a significant difference between the attention span of down syndrome and healthy children.
Conclusion: This research evaluated that down syndrome children have less attention span than healthy children of same age group. Therefore, down syndrome children need more attention training.
Keywords: Attention span, Down syndrome, healthy children, Comparison.

This study examined consumer preference and demand analysis for meat in Kano metropolis. Primary data were collected through a well-structured questionnaire, a total of one hundred and fifty 158 member of household was selected for this study. It was revealed that majority (72.2%) of consumers earns monthly income of N15, 000-N55, 000. Hedonic regression for meat attributes affecting Price shows that meat flavour (Good) was the reference group while meat with bad flavour was entered as dummy variables and the result shows that meat with good flavour was statistically significant at (P< 0.05) with positive coefficient implying that for any unit increase in these variables, buyers would be willing to pay premium because they showed higher significant buyer preference level, results also shows that meat with good taste was statistically significant at (P< 0.05) with positive coefficient this implying that meat with good taste are point of interest for the consumers and they are ready to pay high premium to buy the commodities with this attributes. It was revealed that amount of fat (high ) was found to be statistically significant with a negative coefficient, implying that meat with low fat is more preferable and are selling at higher prices in the study area. Low income of consumer was the highest constraints associated with meat consumption in the study area, with a mean rank of 3.01, followed by high selling price with the mean rank of 3.63 and food safety with 4.20.

Soil salinization is becoming a more serious issue threatening agricultural production and the sustainable use of land resources. Crop roots are unable to absorb water from the soil when exposed to saline conditions. This study explored the potential of Landsat imagery in detecting and mapping saline soil in the Kano River Irrigation Scheme (KRIS). Samples of soil were collected from thirty-nine (39) sectors of the KRIS for ground truthing on 20th – 25th April, 2020. Electrical Conductivity (EC) of field samples were correlated with band values of satellite images and salinity indices in order to determine their relationship and assess their effectiveness in predicting soil salinity. Using a geospatial approach, the data was analyzed and maps of salt-affected areas were generated. ArcGIS 10.6 was used as the primary package for modeling and running functions. The result has shown that the EC values over the entire study area are greater than 1.3 dS/m. However, the mean value of EC is approximately 1.91 dS/m. The implication is that, most of the vegetables such as Onion, Carrot, and Beans grown in the KRIS will experience yield reduction without appropriate management practice as their threshold value has been exceeded.

Published: March 2023

Seed germination of baobab has necessitated with quiescence and hard seed coat impermeable to water and gases. It faces a high risk of extinction due to lack of regeneration. An experiment was carried out to investigate the effect of pre-sowing treatment techniques on seed germination of Baobab. Pot trials were conducted during 2021 dry season at Biological garden, Department of Plant Science and Biotechnology, Faculty of Life Science, Federal University Dutsin-Ma, Katsina State using completely randomized design (CRD). Seeds were subjected to four different concentrations of sulphuric acid, hot water, cold water, physical treatment and untreated seed as control and were analyzed independently to obtain the best treatment periods. Total of nine hundred and sixty (960) viable seeds were surface sterilized in 1.0% Sodium-hypochlorite (NaOCl) for 1 minute and rinsed three (3) times in sterile distilled water. 20 viable seeds were sown for each polypot. Physical pre-sowing treatment with full-sided scarification and treatment with hot water for 10 minutes produces the highest germination percentage (95.00%) and early seedling emergence (7th day after sowing). Seeds soaked in cold water for 8.00 hours gave the least mean days of seedling emergence (6th day after sowing) when compared to other treatments. These results suggested that full side scarification, soaking seed in hot water for 10 minutes and cold water for 8.00 hours were optimum in breaking seed dormancy in Baobab and the techniques could be apply prior to planting to improve germination performance.

BackgroundPathogenic variants in DSP associate with cardiac and cutaneous manifestations including arrhythmogenic right ventricular cardiomyopathy, dilated cardiomyopathy, curly or wavy hair, and palmoplantar keratoderma (PPK). Episodes of myocardial inflammation associated with DSP cardiomyopathy might be confused in clinical work with myocarditis of other etiologies such as viral. Cardiac magnetic resonance imaging (CMR) may help in differential diagnosis.Methods and resultsThis study comprised 49 Finnish patients: 34 participants from families with suspected DSP cardiomyopathy (9 index patients and 25 family members) and 15 patients with myocarditis. All 34 participants underwent genetic testing and cardiac evaluation, and 29 of them also underwent CMR. Participants with the DSP variant, numbering 22, were dermatologically examined. The 15 patients with myocarditis underwent CMR and were evaluated during their hospitalization.A heterozygous truncating DSP c.6310delA p.(Thr2104Glnfs*12) variant was confirmed in 29 participants. Only participants with the DSP variant had pacemakers and life-threatening ventricular arrhythmias. Of the participants with the DSP variant, 24% fulfilled cardiomyopathy criteria, and the median age at diagnosis was 53. Upon CMR, myocardial edema was found to be more common in patients with myocarditis. Both groups had a substantial percentage of late gadolinium enhancement (LGE). A ring-like LGE and increased trabeculation were observed only in participants with the DSP variant. All the studied participants with the DSP variant had PPK and curly or wavy hair. Hyperkeratosis developed before the age of 20 in most patients.ConclusionsThe DSP c.6310delA p.(Thr2104Glnfs*12) variant associates with curly hair, PPK, and arrhythmogenic cardiomyopathy with increased trabeculation. Cutaneous symptoms developing in childhood and adolescence might help recognize these patients at an earlier stage. CMR, together with dermatologic characteristics, may help in diagnosis.

IntroductionVirtual conversational agents (i.e., chatbots) are an intuitive form of data collection. Understanding older adults' experiences with chatbots could help identify their usability needs. This quality improvement study evaluated older adults' experiences with a chatbot for health data collection. A secondary goal was to understand how perceptions differed based on length of chatbot forms.MethodsAfter a demographic survey, participants (≥60 years) completed either a short (21 questions), moderate (30 questions), or long (66 questions) chatbot form. Perceived ease-of-use, usefulness, usability, likelihood to recommend, and cognitive load were measured post-test. Qualitative and quantitative analyses were used.ResultsA total of 260 participants reported on usability and satisfaction metrics including perceived ease-of-use (5.8/7), usefulness (4.7/7), usability (5.4/7), and likelihood to recommend (Net Promoter Score = 0). Cognitive load (12.3/100) was low. There was a statistically significant difference in perceived usefulness between groups, with a significantly higher mean perceived usefulness for Group 1 than Group 3. No other group differences were observed. The chatbot was perceived as quick, easy, and pleasant with concerns about technical issues, privacy, and security. Participants provided suggestions to enhance progress tracking, edit responses, improve readability, and have options to ask questions.DiscussionOlder adults found the chatbot to be easy, useful, and usable. The chatbot required low cognitive load demonstrating it could be an enjoyable health data collection tool for older adults. These results will inform the development of a health data collection chatbot technology.

Published: March 2023

BackgroundBone age is the age of skeletal development and is a direct indicator of physical growth and development in children. Most bone age assessment (BAA) systems use direct regression with the entire hand bone map or first segmenting the region of interest (ROI) using the clinical a priori method and then deriving the bone age based on the characteristics of the ROI, which takes more time and requires more computation.Materials and methodsKey bone grades and locations were determined using three real-time target detection models and Key Bone Search (KBS) post-processing using the RUS-CHN approach, and then the age of the bones was predicted using a Lightgbm regression model. Intersection over Union (IOU) was used to evaluate the precision of the key bone locations, while the mean absolute error (MAE), the root mean square error (RMSE), and the root mean squared percentage error (RMSPE) were used to evaluate the discrepancy between predicted and true bone age. The model was finally transformed into an Open Neural Network Exchange (ONNX) model and tested for inference speed on the GPU (RTX 3060).ResultsThe three real-time models achieved good results with an average (IOU) of no less than 0.9 in all key bones. The most accurate outcomes for the inference results utilizing KBS were a MAE of 0.35 years, a RMSE of 0.46 years, and a RMSPE of 0.11. Using the GPU RTX3060 for inference, the critical bone level and position inference time was 26 ms. The bone age inference time was 2 ms.ConclusionsWe developed an automated end-to-end BAA system that is based on real-time target detection, obtaining key bone developmental grade and location in a single pass with the aid of KBS, and using Lightgbm to obtain bone age, capable of outputting results in real-time with good accuracy and stability, and able to be used without hand-shaped segmentation. The BAA system automatically implements the entire process of the RUS-CHN method and outputs information on the location and developmental grade of the 13 key bones of the RUS-CHN method along with the bone age to assist the physician in making judgments, making full use of clinical a priori knowledge.

BackgroundRheumatoid arthritis (RA), a chronic autoimmune inflammatory disease, is often characterized by persistent morning stiffness, joint pain, and swelling. Early diagnosis and timely treatment of RA can effectively delay the progression of the condition and significantly reduce the incidence of disability. In the study, we explored the function of pyroptosis-related genes (PRGs) in the diagnosis and classification of rheumatoid arthritis based on Gene Expression Omnibus (GEO) datasets.MethodWe downloaded the GSE93272 dataset from the GEO database, which contains 35 healthy controls and 67 RA patients. Firstly, the GSE93272 was normalized by the R software “limma” package. Then, we screened PRGs by SVM-RFE, LASSO, and RF algorithms. To further investigate the prevalence of RA, we established a nomogram model. Besides, we grouped gene expression profiles into two clusters and explored their relationship with infiltrating immune cells. Finally, we analyzed the relationship between the two clusters and the cytokines.ResultCHMP3, TP53, AIM2, NLRP1, and PLCG1 were identified as PRGs. The nomogram model revealed that decision-making based on established model might be beneficial for RA patients, and the predictive power of the nomogram model was significant. In addition, we identified two different pyroptosis patterns (pyroptosis clusters A and B) based on the 5 PRGs. We found that eosinophil, gamma delta T cell, macrophage, natural killer cell, regulatory T cell, type 17 T helper cell, and type 2 T helper cell were significant high expressed in cluster B. And, we identified gene clusters A and B based on 56 differentially expressed genes (DEGs) between pyroptosis cluster A and B. And we calculated the pyroptosis score for each sample to quantify the different patterns. The patients in pyroptosis cluster B or gene cluster B had higher pyroptosis scores than those in pyroptosis cluster A or gene cluster A.ConclusionIn summary, PRGs play vital roles in the development and occurrence of RA. Our findings might provide novel views for the immunotherapy strategies with RA.
