Background: Adult patients with Acute Myeloid Leukemia (AML) have traditionally been hospitalized for the duration of intensive consolidation chemotherapy until blood count recovery to avoid complications. Recently, there has been a trend to shift the care of AML patients treated with intensive chemotherapy from inpatient to outpatient settings to reduce treatment costs and save beds. Methods and materials: A retrospective study of AML patients who received cytarabine consolidation chemotherapy between the 1st of August 2016 and the 31st of December 2023 at King Fahad Specialist Hospital in Dammam, Saudi Arabia was performed. Results: Over a period of 7 years and 4 months, 62 patients received a total of 127 cycles of intensive consolidation chemotherapy at outpatient setting. At diagnosis: 12 patients had extramedullary disease, and 17 patients had adverse cytogenetic abnormalities. Following the 127 cycles of chemotherapy, 38 episodes of febrile neutropenia were encountered, and 46 hospital admissions were required. No complications were encountered following 62.2% of the cycles of consolidation therapy and no early mortality due to intensive consolidation therapy was reported. Out of 62 patients studied, 36 patients underwent various forms of hematopoietic stem cell transplantation. Disease relapses were encountered in 24 patients and the 5-year incidence of relapse for the entire group of patients was 42%. The 5-year leukemia-free survival for the: entire study patients, transplanted patients, and non-transplanted patients were: 43%, 38%, and 50% respectively. The 5-year overall survival for the: entire study patients, transplanted patients, and non-transplanted patients were: 44%, 34%, and 65% respectively. At the end of follow-up: 37 patients (59.68%) were alive, 24 patients (38.71%) were dead, and the fate of 1 patient (1.61%) was unknown as the patient moved to another hospital. Conclusion: Administration of intensive consolidation chemotherapy for patients with AML at outpatient setting is safe, feasible, and cost-effective. The incidence of infectious complications was relatively low. No early treatment-related mortality due to intensive consolidation therapy was encountered. Outpatient administration of intensive consolidation therapy can save beds, reduce hospital costs, and is associated with short-term and long-term outcomes that are comparable to inpatient administration of consolidation therapy.

Authors: Kaysimo Geremu , Tadele Yilkal
Published: May 2024

Local brewery byproducts such as atella and tata, resulting from several fermented beverages, are used as animal feed in Ethiopia. However, there is no sufficient information on the nutritional value of those feed resources for animals. The objective of this study was to evaluate the effects of supplementing local brewery by-products on feed intake, body weight change, and economic profitability of Woyto–Guji goats fed on hay. Twenty-four yearling intact Woyto-Guji male goats were used. The experiment was conducted using a completely randomized block design. The goats were blocked into six groups of four animals based on initial body weight and randomly assigned to four different dietary treatments: hayalone (T1); haycombined with atella (T2); hay combined withtata (T3); and hay combined with an atella-tata mixture (1:1) (T4). The crude protein content of hay, atella, tata, and the atella-tata mixture used in this study were 7.35, 18.47, 17.51 and 17.86%, respectively. Dry matter intakes of 564.56 (T1), 810.27 (T2), 850.37 (T3), and 945.85 (T4) g/day, and crude protein intakes of 45.27 (T1), 104.18 (T2), 103.79 (T3), and 112.96 (T4) g/day were recorded. Total body weight gains were 2.76, 8.03, 6.15 and 9.72 Kg for the same treatments, respectively. Atella and tata, either supplemented alone or combined, increased body weight. The highest body weight gain was recorded in goats fed atella-tata mixture. All treatments had a positive net return.

Pig farming is an important component of the livestock sector at a global scale since pork is the most widely produced and consumed meat in the world. This study aimed to evaluate the effects of diets containing different levels of fermented coffee husk flour on the productive performance of pigs and economic viability in pig farming. Coffee husks were incorporated with probiotics based on Moringaoleifera Lam leaf extracts. Five gilts between 3 to 5 months of age, with an initial average weight of around 13.38 kg, were used. The experiment was conducted using a Latin Square Design, with 5 treatments and 5 replications. The treatments were a control treatment (T0) without coffee husks in the diet; and treatments T1, T2, T3, and T4 with coffee husks at 4%, 6%, 8%, and 10% in the diet, respectively. The statistical analysis showed that T1, which contained 4% fermented coffee husks in the diet, was the most efficient diet formulation with respect to the rest of the treatments. The animals that received T1 showed a high increase in average daily weight, with an average value of 867.70 g; and a better feed conversion rate, requiring only 3.57 kg to produce one kilogram of meat. The results of a descriptive yield analysis on feed cost showed that T1 could generate a higher yield of about $6.04 per kilogram of meat sold in the local market compared to the other treatments. Therefore, it is concluded that the incorporation of fermented coffee husks at 4% into pig diets can improve pig productive performance and reduce feed costs.

The objective of this study was to evaluate the relationship between body weight (BW) and different biometric measurements in llamas (Lama glama) from the Bolivian highlands and to generate prediction models of BW. A total of 515 individual records of BW and biometric measurements were used. The measurements were taken on 202 males and 313 females aged between 0.5 and 5 years, and included: neck length (NL), withers height (WH), rump height (RH), heart girth (HG), body length (BL), abdomen circumference (AC), rib depth (RD), hip width (HW), pin bone width (PBW), thoracic width (TW), and back length (BKL). The relationships between BW and biometric measurements were developed using simple linear and multiple regression. For the evaluation, the relationship between the observed and predicted values of BW was determined by linear regression, the mean squared error of prediction (MSEP) and root MSEP (RMSEP); concordance correlation coefficient analysis was also used. The BW ranged from 22 to 122 kg. Regression equations between BW, HG and RD had an r2 of 0.94 and 0.92, respectively (RMSEP= 6.06 and 6.70 kg, respectively). The equations were highly precise (r2 >0.86) and accurate (Cb>0.98), with a reproducibility index > 0.92. The model efficiency (MEF) indicated a higher efficiency of prediction (MEF ≥ 0.86). Using a single predictor, HG and RD accounted for more than 92% of the variation in BW. Overall, HG may be used as a single predictor to predict BW in llamas maintained under the conditions of the Bolivian highlands.

Causes of fracturing and evidence of coal seam deforming in the vibration impact zone

The use of vibration effects for the effective preparation of a low–permeability coal seam is a fairly promising and constantly improving process. The main difficulty of theoretical research is the fact that coal seams are very diverse in their properties and represent a complex environment. Under the influence of vibration, the capacitive and filtration characteristics of the coal massif change. This leads to a change in the structure and capacity of the porous-fissured space of coal. This reaction finds a good explanation: each act of vibration action causes a rapid change in the coal mass in accordance with the operating stresses during vibration. This point of view was used as the basis for theoretical reasoning, in order to justify the rational impact of directional vibration on the coal seam, to change fracturing and further intensify methane recovery. This is confirmed by both laboratory and industrial experiments on vibration effects. Changes in the environment after strong earthquakes are of a similar nature, even at great distances from the source of the impact. Therefore, the simplest in terms of constructive implementation and less costly in terms of energy and material consumption is a directed oscillatory process on a low-permeability coal seam, which is performed using vibration installations of both surface and underground design.

Authors: Rakitin V.A. , Malakhov Yu.V. , Pashkov D.A.
Published: May 2024

The article presents the issue of short life of pneumatic tyres for mobile underground mining machines. It is noted that the correct choice of pneumatic tyres will increase the tyre life, but for a greater increase it is necessary to control the entire life cycle of the tyre, i.e. to carry out its service. The life cycle stages to be taken into account during tyre maintenance are presented. Control at each stage will minimise damage to the pneumatic tyres. The maintenance phase should include the records of tyre usage history and stock management. Analysis of the records will help to determine the reasons for tyre rejection and the wear conditions, the tyre condition before and after repair, and before and after retreading. Service maintenance of pneumatic tyres will allow planning the approximate level of stock, replacement periods and effective stock management. The article justifies the relevance of holding joint meetings of service specialists, tyre designers, and the company’s. In conclusion, it is noted that the issue of creating a national standard of service maintenance of pneumatic tyres for mobile underground mining machines is relevant.
A critical analysis of the European Union’s structure and approach to economic recovery during times of crisis
Authors: Stayt Hamish
Published: May 2024

This essay critically analyses the European Union's (EU) approach to economic recovery during times of crisis, focusing on the 2008 financial crisis and the subsequent eurozone debt crisis. The EU's response included various measures such as bailouts, fiscal stimulus packages, and structural reforms. However, shortcomings in these responses are evident, including a lack of long-term planning and the exacerbation of negative effects by bailout announcements. Moreover, the essay examines structural issues within the EU, particularly regarding the European Central Bank's monetary policies and the lack of cohesive fiscal policies among member states. These structural deficiencies contributed to the severity of the crises. Despite lessons learned, including the need for stricter financial regulations and improved coordination among member states, challenges remain. The analysis suggests that while the EU has undergone reforms, its resilience to future crises remains uncertain.

Unguentaria and Related Vessels in the Mediterranean from the Early Hellenistic to the Early Byzantine Period
Authors: Kan Şahin Gülseren
Published: May 2024

This book provides comprehensive analyses of the clay and glass unguentaria and related vessels (such as pelikai and alabastra) from the Late Classical to the Early Byzantine periods that have been found across the Mediterranean. It defines these vessels, classifies them by type, dates them, and examines their contexts, functions, regional variations, probable contents, and distribution patterns. The text presents evidence of how unguentaria evolved in type and how their shapes and decorations reflected their functions. It also explores the major production centers, methods, and innovations of unguentaria and related vessels. A primary aim is to outline a sensory approach to Greek and Roman burials and contribute to the “function versus form” debate. The conclusions contain implications for further research on funerary practices, local identities, and social statuses in settlements and their regions.
