Current application directions for the weathering rind of molybdenum deposits of Ukraine
Authors: Miroshnykov I
Published: April 2024

Purpose. Justification of the new direction of using molybdenum ores from weathering rind of deposits of Ukraine. Research methodology. The research was carried out by general scientific and special research methods – theoretical (analysis, explanation, generalization, comparison), technical and economic evaluation. Research results. The conducted research made it possible to determine the main global approaches to the extraction and application of molybdenum in various areas of industry. The importance of the domestic industry's need for molybdenum-containing fertilizers is substantiated. The reasons why modern global methods for obtaining molybdenum-containing fertilizers are difficult have been revealed. It has been found that modern extraction of molybdenum occurs from native ores, and attempts to extract molybdenum from weathered ores are considered ineffective. The conducted studies indicate significant areas of weathering rinds in Ukraine, including on molybdenum ore occurrences. It is possible to use such weathering rinds as fertilizers directly, that is, bypassing the traditional production of concentrates. The reduction of molybdenum deficiency in Ukrainian arable soils can be achieved by using the weathering crust of molybdenum ore occurrences by soil exchange between enriched soils of ore deposit locations and depleted soils of seeded fields. The originality. For the first time, the regularity of correspondence between the mining term "significantly weathered molybdenum-containing ore" and the agricultural term "molybdenum-contaminated soil" was established. Significant volumes of such ore (soil) in Ukraine were confirmed, and the presence of signs of a promising molybdenum resource in it was also investigated. Practical value. The obtained data make it possible to partially solve the needs of Ukraine in molybdenum, which is currently not mined. The results of the research made it possible to substantiate the direction of the application of molybdenum weathering crust for the domestic agricultural industry, which increases the yield, quality of agricultural products, cultivated areas, income to the foreign currency budget due to the increase in the export of agricultural products, customs duties and taxes.

Authors: Yakovyshyna T
Published: April 2024

Purpose. Analysis of the features of the practical application of well-known methods for determining the energy and environmental indicators of boiler houses in the systems of heating networks of the city "before" and "after" the introduction of thermal modernization of residential buildingsnetwork. The methods. provides for a critical analysis of the existing methodology for determining emissions into the atmosphere from power plants and recommendations for determining the energy and environmental efficiency of thermal modernization of buildingsimplementation of thermal modernization of residential buildingsnetwork. Findings. The analysis of the standardized methodology for calculating emissions of pollutants into the atmosphere from power plants, including urban boiler houses, showed the need for its improvement by separating from the calculated indicators of fuel consumption and emissions the share due to the implemented thermal modernization. It is recommended to supplement this methodology with the calculation of the "energy ecological index" (K) proposed in 2020.The peculiarity of the application of this index in the conditions of the boiler house, where any thermal modernization has taken place, is to select the current fuel consumption "before" and "after" its implementation, but determined at the same atmospheric temperature, for example, 0 °C, and accordingly calculate a pair of index values. The difference between them will allow you to first estimate the value of fuel conservation (savings), i.e. the energy effect of thermal modernization, and then calculate the difference between the corresponding current pairs of emission values of each pollutant, as the environmental effect of thermal modernization. The originality consists in recommending the improvement of the standardized methodology by allocating from the determined fuel consumption and emissions the share due to the implemented thermal modernization, based on the use of a well-known energy ecological index, for the calculation of which it is necessary to select the current fuel consumption "before" and "after" thermal modernization, but determined at the same atmospheric temperature. Practical implementation. The obtained calculated indicators are proposed to be used to determine the energy and environmental efficiency of thermal modernization in the system of a certain boiler house, including buildings as factors of environmental safety of the city territories.

Published: April 2024

Calf starter is a special feed preparation that is fed to calves to ensure smooth weaning of calves. The study was conducted to evaluate the growth performance of crossbred dairy calves (Holstein-Friesian crossbred, HFX and Sahiwal crossbred, ShX) feeding a readily fermentable calf starter diet. The duration of the study was 17 weeks of which the first week was for the adjustment period. Ten healthy crossbred heifer calves of average 40 days old were selected for this purpose and they were divided into two groups according to their genetic materials (5 HFX and 5 ShX) in a completely randomized design. The calves were fed initially 0.25kg/day/calf of starter feed which was gradually increased up to 1 kg/day/calf. In addition to calf starter, a predetermined amount of whole milk (2 kg/day/calf) and ad libitum amount of green grass were also supplied to the calves. During the experimental period, growth parameters viz. body weight gain, body length gain, wither height gain, and hip height gain was measured weekly. After the whole study period, no significant difference (P>0.05) was found in case of the average weekly body weight gain and all the body measurements. The results suggest that calves fed a balanced calf starter can grow identically overcoming any breed variations. However, to provide a clearer idea about the effect of calf starter on different crossbred dairy calves broad-scale research should be conducted on an advanced level including more crossbreds or pure breeds.

Improving patient access to valuable new pharmaceuticals
Authors:   , Kalf Rachel Rishma Johanna
Published: April 2024

The focus of this thesis was the use of patient-relevant outcome measures in health technology assessment (HTA) reimbursement recommendations and the potential to improve alignment with other stakeholders in the healthcare field. Part A of this thesis showed some overlap between health outcomes used for market access, reimbursement recommendations and in healthcare quality improvement already exists. In addition these outcomes seem to be patient relevant since these are also included in International Consortium for Health Outcomes Measurement (ICHOM) standard sets. However, a greater level of alignment seems attainable, for example by using the same definitions for similar health outcomes or using the same health related quality of life (HRQoL) questionnaires. Residual discrepancies may however remain due to the different remits of each of the actors.

Although information on HRQoL has become increasingly important for market authorization and reimbursement recommendations this information is often not systematically collected. Therefore part B of this thesis explored how information derived from social media could provide additional input for HTA reports that support reimbursement recommendations. Social media was shown to be a readily available source of information that can provide fast input on HRQoL from patients with both rare and common diseases. It can be used to listen to what patients discuss on the web and to distribute questionnaires. However, health data from social media is prone to selection and information bias, and validating authenticity can be difficult. Therefore, this type of data should be used complementary to traditional forms of research.

Even when there is agreement in health outcomes between the different actors in the healthcare field there may still be some differences to allow each of those actors to pursue their purpose. One specific difference is the use of different comparators, for example a placebo or a treatment used in clinical practice. Part C investigated the potential of using indirect treatment comparisons for reimbursement recommendations. Indirect treatment comparisons were shown be evaluated regularly for reimbursement recommendations by the Dutch and English HTA agencies. Indirect evidence may have a substantial impact on the conclusion of the relative effectiveness assessment, however the effect on the cost effectiveness assessment and final recommendation is difficult to extract since multiple factors play a role.
Clinical Decision Support for Rheumatoid Arthritis & Primary Antibody Deficiencies
Authors:   , Messelink Marianne Alice
Published: April 2024

A clinical decision support system (CDSS) generates a patient-specific medical recommendation, which is then presented to the clinician for consideration. Recommendations can be made for e.g. diagnoses, additional exams or medical treatment. A CDSS can be rule-based (e.g. derived from literature or clinical guidelines), or it can be based on a prediction model. This thesis is about the development and implementation of CDSSs for rheumatoid arthritis (RA) and primary antibody deficiencies (PAD). RA is a chronic auto-immune disease that is characterized by inflammation of the synovial joints. PAD are a heterogeneous group of immunodeficiencies that can result in recurrent infections and auto-immune symptoms, among other complaints.

This thesis has several parts. The first part described the RA patient perspective on the use of prediction models as a support in their medical treatment. In the second part we focus on diagnostic decision support. We describe different methods for the identification of patients with difficult-to-treat RA in routine care data, and we describe the development of a CDSS for the early recognition of PAD in primary care. The third part focuses on treatment decision support. We describe the development of a CDSS that aims to reduce the risk of disease flares when tapering RA medication.

Authors: Zelinka T , Widimský J
Published: April 2024

The aim of our study was to evaluate the potential differences in blood pressure (BP) profile in subjects with different forms of primary aldosteronism (PA). Simultaneously, we studied the effects of PA treatment on BP curve. We therefore monitored 24-hour ambulatory blood pressure values in 22 subjects with aldosterone-producing adenoma (APA), 22 subjects with idiopathic hyperaldosteronism (IHA) and 33 subjects with essential hypertension (EH) as controls. We found a significantly attenuated nighttime systolic BP decline in the APA group (P=0.02). Patients with IHA had lower nighttime systolic BP values (P=0.01) and also a diastolic BP decline (P=0.02) during the night in comparison with EH. We did not detect any significant differences in BP profile characteristics between APA and IHA. Specific treatment of primary aldosteronism (adrenalectomy, treatment with spironolactone) led to the normalization of the BP curve with a marked BP decline. Our study thus demonstrates a blunted diurnal BP variability in patients with primary aldosteronism the specific treatment of which normalized previously attenuated nocturnal BP fall.

Introduction: Progesterone and oestrogen can have an impact on benign smooth muscle tumours of the uterus called uterine myomas. The majority of fibroids don’t cause any symptoms and don’t need to be treated or investigated further. Fibroids originate in the smooth muscles of the uterus and move to an area of decreased resistance, where they can either stay intra-myometrial or develop into subserosal or submucous myomas. Aim of the Work: This study’s primary goal was to find out if oxytocin intrauterine infusion into the distention medium during hysteroscopic myomectomy would lessen blood loss and enhance surgical visibility. Patients and Methods: This clinical trial was undertaken at the Early Cancer Detection Unit (ECDU) at Ain Shams University hospitals using a randomised controlled double blind design. Sixty women who were scheduled for a hysteroscopic myomectomy were enrolled in this study and split into two equal groups: Group A (Oxytocin group): 10 IU of oxytocin were administered for every 1000 millilitres of the distending medium during the hysteroscopic myomectomy performed on 30 women. Group B (Placebo group): Thirty women had hysteroscopic myomectomy, and for every 1000 millilitres of the distending medium, a sterile bacteriostatic water ampule was used. Results: There was no statistically significant difference between the groups’ demographic (age) and surgical (myoma size, number, and duration of operation) data, nor were there any differences in intraoperative fluids. Each group’s Hgb and Hct decrease exhibited a significant difference, with the control group exhibiting a greater mean difference than the oxytocin group. Our findings demonstrated that there was a statistically significant difference in post-operative Hgb and HCT between groups, and that groups were similar in terms of needing blood transfusions and needing a second operation. When it came to the surgeon’s assessment of the visual fluid clarity, the groups were equivalent, but there was a statistically significant difference in the surgeons’ ratings of bleeding. According to our findings, there was no statistically significant variation in the number of uterine and medical difficulties across the groups, and the groups’ levels of complications were comparable. Conclusion: During diagnostic hysteroscopy, complications frequently arise. During a hysteroscopic myomectomy, oxytocin is infused intrauterine into the distention medium to minimise blood loss and enhance operative visibility. To confirm these results, more research using a range of doses and techniques is required.

Introduction: Temporal global trends of sperm quality remain a matter of debate. It is widely believed that exposure to endocrine disruptors during fetal life can damage testicular function, cause testicular cancer and impair reproduction. Materials and methods: This was a retrospective, cohort study using data from a single IVF center located in Thessaloniki, Greece, during the period 2004-2013; including male partners of infertile Greek women, undergoing oocyte donation treatment for the first time. Local polynomial smoothing was used to assess visually possible trends in the data. One-way ANOVA was used for the comparison of means of variables of interest between years. The Pearson Chi-squared and the Chi-squared test for trend were employed to test for the independence and trend respectively of the occurrence of concentrations <20 million/ml and the year of study. Results: A total of 1113 participants were analyzed. The mean sperm concentration increased significantly between 2004 and 2012 (39.5million/ml versus 59.1million/ml; p<0.001), but without forming a visible upward trend; the mean total motility remained statistically unchanged (56% versus 49.8%; p=0.239), as well as the percentage of sperm concentration of less than 20million/mL (23.5% versus 24.4%; p=0.249), whereas the mean of rapid progressive motile sperm decreased significantly (41.1% versus 30%; p<0.001), forming a visible downward trend. Conclusions: Sperm motility and annual percentage of oligospermic males presenting with a sperm concentration of less than 20 million/mL showed an absence of significant change and temporal trend. Rapid progressive motile sperm deteriorated significantly, revealing a visible time-related downward trend.

This case report presents the clinical course of a 56-year-old woman admitted to the Emergency Department with a complex array of symptoms, including vaginal bleeding, muscular weakness, and severe back pain. Subsequent investigations led to the diagnosis of a highly malignant neoplasm, suspected to be microcellular carcinoma originating from the cervix/uterus. The patient exhibited metastases to the pulmonary parenchyma and cervical spine, necessitating a multidisciplinary approach for comprehensive management. The diagnostic journey involved imaging studies, including MRI and CT scans, and appropriate interventions, such as diagnostic curettage. Treatment modalities included radiotherapy and chemotherapy, resulting in notable clinical improvement.
