Published: February 2023

Each area of a country, due to its specific soil and climatic conditions, requires the elaboration of a biological grounding for the introduction of useful plants which might be lead to the best practical effect when cultivated both under production conditions and on garden plots. In this respect, the introduction of new species is of crucial importance.
Research regarding chia (Salvia hispanica L.) has been conducted at Omsk State Agrarian University since 2017. This crop has been cultivated in Mexico since ancient times, while in Russia it has not been grown yet. The present article shows the scientific results of the research on chia as a new, versatile crop to be cultivated under the conditions of the southern forest-steppe of Western Siberia. Varietal studies were conducted on samples from different countries, including Mexico, France, Israel and Thailand.
The sample assessment was carried on at the breeding nursery according to the following parameters: duration of the growing period, productivity and sucrose content in their leaves. In order to increase the efficiency of the breeding process when creating new chia varieties, the samples 3/18 and 0/18 can be recommended as sources due to their parameter set.

The research aim was to study the peculiarities of the formation of productivity of current varieties of oats of domestic selection (Argamak, Krechet, Yakov) when grown on different backgrounds of mineral nutrition (1-natural fertility (without fertilizers), 2 – N16P16K16 when sown +N45 in the feeding (tillering phase), 3 – N16P16K16 during sowing +N90 in feeding) and foliar treatments in the tillering phase with humic preparation Humate+7; give recommendations to the production based on the results obtained. Comprehensive research was conducted in 2018–2020 on the fields of the Educational Scientific and Innovative Production Center “Agrotechnopark” of the Tver State Agricultural Academy. Field and laboratory researches of photosynthetic activity indicators, crop structure, yield accounting, grain quality, mathematical processing of the results were carried out according to well-tested methods in agriculture. It was found that the greatest responsiveness to the applied fertilizers was distinguished by seed oats of the Yakov variety. The crops of this variety were obtained with foliar treatment at the tillering stage with a 1% working solution of Humate+7 against the background of application of N16P16K16 at sowing and N90 in feeding grain yield. It is equal to 4.77 t/ha with the greatest grain in the experience – 559 g/l (which corresponds to the grain of the 1st class), and the lowest filminess is 23.4%. These features of the fertilizer system had a positive effect on the crops of all the studied varieties of oats. That allows us to recommend their production as the most promising. At the same time, it is worth noting that non-root feeding with Humate+7 is effective both in conditions of reducing doses of mineral fertilizers and in their complete absence, increasing grain yield by an average of 27.0%–31.5%. The increase in crop productivity is associated with an increase in the photosynthetic activity of plants in crops and an improvement in the main parameters of the crop structure (the density of the productive stem, the weight of grain from the panicle).

Introduction
First-trimester anatomical screening (FTAS) by ultrasound has been introduced in many countries as screening for aneuploidies, but also as early screening for fetal structural abnormalities. While a lot of emphasis has been put on the detection rates of FTAS, little is known about the performance of quality control programs and the sonographers’ learning curve for FTAS. The aims of the study were to evaluate the performance of a score-based quality control system for the FTAS and to assess the learning curves of sonographers by evaluating the images of the anatomical planes that were part of the FTAS protocol.

Methods
Between 2012–2015, pregnant women opting for the combined test in the North-Netherlands were also invited to participate in a prospective cohort study extending the ultrasound investigation to include a first-trimester ultrasound performed according to a protocol. All anatomical planes included in the protocol were documented by pictures stored for each examination in logbooks. The logbooks of six sonographers were independently assessed by two fetal medicine experts. For each sonographer, logbooks of examination 25-50-75 and 100 plus four additional randomly selected logbooks were scored for correct visualization of 12 organ-system planes. A plane specific score of at least 70% was considered sufficient. The intra-class correlation coefficient (ICC), was used to measure inter-assessor agreement for the cut-off scores. Organ-specific learning curves were defined by single-cumulative sum (CUSUM) analysis.

Results
Sixty-four logbooks were assessed. Mean duration of the scan was 22 ± 6 minutes and mean gestational age was 12+6 weeks. In total 57% of the logbooks graded as sufficient. Most sufficient scores were obtained for the fetal skull (88%) and brain (70%), while the lowest scores were for the face (29%) and spine (38%). Five sonographers showed a learning curve for the skull and the stomach, four for the brain and limbs, three for the bladder and kidneys, two for the diaphragm and abdominal wall and one for the heart and spine and none for the face and neck.

Conclusion
Learning curves for FTAS differ per organ system and per sonographer. Although score-based evaluation can validly assess image quality, more dynamic approaches may better reflect clinical performance.

Published: February 2023

Introduction
In a nationwide survey of practices, we sought to define the criteria, circumstances and consequences of non-beneficial admissions to the intensive care unit (ICU), with a view to proposing measures to avoid such situations.

Methods
ICU physicians from a French research in ethics network participated in an online survey. The first part recorded age, sex, and years’ experience of the participants. In the second part, there were 8 to 12 proposals on each of 4 main domains: (1) What criteria could be used to qualify an ICU stay as non-beneficial? (2) What circumstances result in the admission of a patient whose ICU stay may later be deemed non-beneficial? (3) What are the consequences of a non-beneficial stay in the ICU? (4) What measures could be implemented to avoid admissions that later come to be considered as non-beneficial? Responses were on a 5-point Likert scale ranging from “Strongly disagree” to “Strongly agree”.

Results
Among 164 physicians contacted, 154 (94%) responded. The majority cited several criteria used to qualify a stay as non-beneficial. Similarly, >80% cited several possible circumstances that could result in non-beneficial admissions, including lack of knowledge of the case and the patient’s history, and failure to anticipate acute deterioration. Possible consequences of non-beneficial stays included stress and anxiety for the patient/family, misunderstandings and conflict. Discussing the utility of possible ICU admission in the framework of the patient’s overall healthcare goals was hailed as a means to prevent non-beneficial admissions.

Conclusion
The results of this survey suggest that joint discussions should take place during the patient’s healthcare trajectory, before the acute need for ICU arises, with a view to limiting or avoiding ICU stays that may later come to be deemed “non-beneficial”.

Introduction
Anemia is a serious complication of chronic kidney disease (CKD) with a significant adverse outcome on the burden and progression of the disease. Hence, the study intended to assess the pooled prevalence of anemia and its predictors among CKD patients in Sub-Saharan African nations.

Methods
To identify the relevant studies systematic searches were carried out in Medline, EMBASE, HINARI, Google Scholar, Science Direct, and Cochrane Library. From selected studies, data were taken out with a standardized data extraction format prepared in Microsoft Excel. Inverse variance (I2) tests were employed to evaluate the heterogeneity across the included studies. Due to substantial heterogeneity among the studies, a random-effects meta-analysis technique was employed to estimate the pooled prevalence of anemia. Subgroup analysis, sensitivity analysis, and meta-regression analysis were carried out to search the possible bases of heterogeneity. Funnel plot symmetry, Begg’s test, and Egger’s regression test were employed to assess the existence of publication bias. In addition, factors associated with anemia among CKD patients were examined. All statistical analyses were carried out with STATA™ Version 14 software.

Results
A total of 25 studies with 5042 study participants were considered in this study. The pooled prevalence of anemia among CKD patients was estimated to be 59.15% (95% CI, 50.02–68.27) with a substantial level of heterogeneity as evidenced by I2 statistics (I2 = 98.1%; p < 0.001). Stage of CKD (3–5) (pooled odds ratio (POR) = 5.33, 95% CI:4.20–6.76), presence of diabetes mellitus (POR = 1.75, 95% CI: 1.10–2.78), hemodialysis history (POR = 3.06, 95% CI: 1.63–5.73), and female sex (POR = 2.50, 95% CI: 1.76–3.55) were significantly related with anemia.

Conclusions
More than half of CKD patients were suffering from anemia. Stage of CKD, presence of DM, hemodialysis history, and being female sex were factors associated with anemia among CKD patients.

ABSTRACT
Autoimmune pancreatitis is a rare fibro-inflammatory disease with 2 distinct subtypes of which each has their own clinical presentation, risk factors, and histopathological patterns. We present a case of newly diagnosed type 1 autoimmune pancreatitis in a symptomatic 54-year-old man with stable ulcerative colitis 1 month after COVID-19 vaccination. Previous reports have indicated that vaccinations can trigger autoimmune disease in predisposed individuals. This case discusses the occurrence of autoimmune pancreatitis triggered after COVID-19 vaccination.

Authors: Lertwilaiwittaya Pongtawat , Weber Frederick H. 
Published: February 2023

ABSTRACT
Small intestinal venous abnormalities are an underrecognized condition as an etiology of overt gastrointestinal (GI) bleeding in patients with Turner syndrome. Evidence-based therapeutic options for these lesions are lacking in the published literature. A 47-year-old woman with Turner syndrome with a 30-year course of recurrent GI bleeding was found to harbor diffuse small intestinal venous ectasias through endoscopic imaging. Achievement of a 21-month clinical remission (elimination of hospitalizations for overt GI bleeding and normalization of hemoglobin concentration) was reached after initiation of tranexamic acid titrated to 2,600 mg daily.

ABSTRACT
Erdheim-Chester disease (ECD) is an exceedingly rare and aggressive disease characterized by foamy CD68 + CDa-histiocytic infiltration into multiple tissues and organs. Only 1,500 cases have been diagnosed since 1930 when ECD was first described. Biliary tract involvement of ECD has only been reported in the literature once. We report a case of ECD causing extrahepatic biliary obstruction without significant bile duct dilation, mimicking primary sclerosing cholangitis or IgG4 disease.

ABSTRACT
Undifferentiated osteoclast-like giant cell carcinomas (UOLGCCs) of the digestive tract are very rare, with only a few cases reported in the literature. An 82-year-old man was referred to the emergency department for melena. Endoscopic examination revealed a hemicircumferential ulcerovegetative lesion, involving the bulbar apex and extending to the second portion of the duodenum; biopsies revealed an UOLGCC. The patient underwent transfusion support therapy, and he was proposed for best supportive care. Duodenal UOLGCC is an extremely rare cause of upper gastrointestinal bleeding. Clinical findings and therapeutic approach represent a challenge in this pathology.

Authors: Xia Feng , Zhang Qiao , Ndhlovu Elijah , Zhang Mingyu , Zou You 
Published: February 2023

INTRODUCTION:
Circulating tumor cells (CTCs) have been suggested to have an important prognostic role in gastrointestinal tumors. We developed a preoperative CTC-based nomogram to predict the prognosis of patients with resectable gastric cancer after surgery and established a risk stratification system based on the nomogram.

METHODS:
From January 2012 to June 2017, we screened 258 patients with gastric cancer treated with surgery from one center as the training cohort and 133 patients with gastric cancer treated with surgery from another as the validation cohort, screened prognostic factors for the training cohort using univariate and multivariate Cox risk proportional models, created predictive overall survival (OS) and a recurrence-free survival (RFS) nomogram, and plotted the receiver operating characteristic curve and calibration curve for this nomogram in the training and validation cohorts. Risk score stratification was performed according to the nomogram, and OS curves were plotted for the low, medium, and high-risk groups using the Kaplan-Meier method.

RESULTS:
The CTC positivity rate was 78.5% in all patients. CTC, TNM stage, and Ki-67 were the prognostic factors affecting OS and RFS after gastric cancer surgery. The nomogram consisted of these 3 variables. In the training group, the area under the curve of the nomogram for OS at 1, 3, and 5 years was 0.918, 0.829, and 0.813, respectively, and the area under the curve for RFS was 0.900, 0884, and 0.839, respectively. There was a statistically significant difference in OS among the low, medium, and high-risk groups according to the risk stratification system constructed from nomogram scores (P < 0.001).

DISCUSSION:
Two nomograms based on preoperative CTC were established to predict OS and RFS after resectable gastric cancer. The 2 nomograms had good discrimination and calibration and significant stratification ability of the risk stratification system established according to them.

Analysis of Strategic Factors for Successful Integrated System Implementation: Experiences from the Co-operative University of Kenya
Authors: Ngala Orucho Michael 
Published: February 2023

An integrated resource planning (ERP) system is essential for automation of manual routine tedious organizational processes. It is meant to improve efficiency and effectiveness at work. However, implementation of such systems, if not properly organized and appropriate strategies put in place to ensure its success, may take unnecessarily longer time than anticipated, or the whole system abandoned all together. This study sought to establish the most effective strategies that ensure successful and timely integrated system implementation. Systems theory and Process theory approaches were used to anchor the study. Case study was adopted as the research design. The population of the study comprised twelve (12) departments within Co-operative University of Kenya where different system modules were rolled out for implementation. Primary data was collected using semi-structured questionnaires. Since data collected was largely categorical in nature, Chi-square was used to analyze relationship between variables. It was established that personal interest and optimism is the most influential strategy in determining success and pace in integrated system implementation. The key recommendation that the study offers as insight to policy makers, body of theory and practitioners is the need to deliberately concentrate on strategies that induce personal interest and optimism among employees so as to ensure success during implementation of a new system or change.

Utilization of hybrid fibers in different types of concrete and their activity
Authors: Hadeed Mohammed , Humad Abeer M. , Al-Gburi Majid 
Published: February 2023

Abstract
In this work, the influence of using hybrid fibers on the mechanical properties of two types of concrete: high-strength concrete (HSC) and lightweight concrete (LWC) was studied. Using hybrid fibers instead of using only one type reduced the negative effect on concrete mechanical performance. The glass fiber (GF) and polypropylene fiber (PPF) were used in different contents ranged from 0.2 to 1% as weight % of binder content. Moreover, combinations of both fibers “GF + PPF” were used in contents % of “0.3 + 0.5%,” “0.5 + 0.5%,” “0.3 + 1%,” and “0.5 + 1%.” LWC mixes were prepared by replacing 40% of the coarse aggregate of reference mix with volcanic material (pumice) as a volumetric replacing. To produce HSC, the water-to-cement ratio was reduced to 0.3, 10% silica fume was added, and 1% super plasticizer was used to obtain the consistency. Compressive strength, splitting strength, and flexural strength tests were carried out. The results showed that using 0.7% GF displayed the highest increases in compressive, splitting tensile, and flexural strength of HSC and LWC mixes. Furthermore, GF exhibited better performance and higher values in compressive, splitting tensile, and flexural strength tests in comparison with PPF. The optimum hybrid fiber content displaying the highest increment of all tested properties in both concrete types, HSC and LWC, was “0.5% GF + 0.5% PPF.”
