BackgroundData quality is a multidimensional term that includes accuracy, precision, completeness, timeliness, integrity, and confidentiality. The quality of data generated by a routine health information system (RHIS) is still very poor in low- and middle-income countries. There is a paucity of studies as to what determines data quality in health facilities in the study area. Therefore, the aim of the present study was to assess the magnitude of the quality of routine health information system data and its determinants among health centers.MethodsA facility-based quantitative study design triangulated by the qualitative method was conducted. A total of 314 health professionals from 32 health centers were selected using a simple random sampling procedure. Data were gathered using a standardized checklist, interviewer-administered questionnaires, and key informant interview guidelines. Descriptive statistics were used to describe variables and binary logistic regression was used to identify factors associated with data quality using STATA version 14. Variables with p-value &lt;0.25 in the bivariate analysis were entered to a multivariable logistic regression analysis. P-values &lt;0.05 at 95% confidence intervals (CI) were taken to be statistically significant. A manual analysis was conducted for the qualitative data collected from purposively selected key informants.ResultsThe study found that the overall data quality at the health centers of West Gojjam Zone was 74% (95% CI 68–78). The complexity of the routine health information system format [adjusted odds ratio (AOR) 3.8; 95% CI 1.7–8.5], problem-solving skills for RHIS tasks (AOR 2.8; 95% CI 1.2–6.4), and knowing duties, roles, and responsibilities were significantly associated with data quality (AOR 12; 95% CI 5.6–25.8), and lack of human resources, poor feedback mechanisms, delay in completing data records, lack of data use, and inadequate training on health information systems were barriers affecting data quality.ConclusionsThe level of data quality among public health centers in the Amhara region was lower than expected at the national level.

Published: March 2023

BackgroundPatients with a chronic disease may have an increased risk of non-adherence to prescribed home-based exercise therapy. We performed a systematic review with the aim to identify variables associated with adherence to home-based exercise therapy in patients with chronic diseases and to grade the quality of evidence for the association between these prognostic factors and adherence.MethodsCohort studies, cross-sectional studies and the experimental arm of randomized trials were identified using a search strategy applied to PubMed, Embase, PsychINFO and CINAHL from inception until August 1, 2022. We included studies with participants ≥18 years with a chronic disease as an indication for home-based exercise therapy and providing data on prognostic factors of adherence to home-based exercise. To structure the data, we categorized the identified prognostic factors into the five WHO-domains; (1) Patient-related, (2) Social/economic, (3) Therapy-related, (4) Condition-related, and (5) Health system factors. Risk of bias was assessed using the Quality in Prognostic Studies (QUIPS) tool. Prognostic factors of adherence were identified and the quality of the evidence between the prognostic factors and adherence were graded using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework for predictor studies. We performed a meta-analysis of the obtained information.ResultsA total of 57 studies were included. Within patient-related factors moderate- and high-quality evidence suggested that more self-efficacy, exercise history, motivation and perceived behavioral control predicted higher adherence. Within social-economic factors moderate-quality evidence suggested more education and physical health to be predictive of higher adherence and within condition-related factors moderate- and low-quality evidence suggested that less comorbidities, depression and fatigue predicted higher adherence. For the domains therapy-related and health-system factors there was not enough information to determine the quality evidence of the prognostic factors.ConclusionThese findings might aid the development of future home-based exercise programs as well as the identification of individuals who may require extra support to benefit from prescribed home-based exercise therapy.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=277003, identifier PROSPERO CRD42021277003.

PurposeThe current study aimed to investigate whether red blood cell distribution width (RDW) can predict the prognosis of patients with breast cancer (BC).MethodsWe searched four databases, including PubMed, Embase, Cochrane Library databases, and CNKI, from inception to Jun 13, 2022. The primary outcome was overall survival (OS), and the secondary outcome was disease-free survival (DFS). A subgroup analysis was conducted based on different treatments. This meta-analysis was performed with RevMan 5.3 (The Cochrane Collaboration, London, United Kingdom).ResultsA total of seven studies including 4,884 BC patients were identified. The high RDW group had a larger tumor size (OR = 2.12, 95% CI = 1.67 to 2.68, P &lt; 0.01), higher proportions of advanced stage tumors (OR = 1.77, 95% CI = 1.38 to 2.27, P &lt; 0.01), more lymph node metastases (OR = 2.00, 95% CI = 1.58 to 2.51, P &lt; 0.01) and lower HER-2 expression (OR = 0.76, 95% CI = 0.61 to 0.95, P = 0.02). For prognosis, after pooling all the data, we found that the high RDW group was associated with worse OS (HR = 2.12, 95% CI = 1.47 to 3.08, P &lt; 0.01) and DFS (HR = 1.77, 95% CI = 1.32 to 2.37, P &lt; 0.01). The subgroup analysis found that RDW had prognostic significance but only for surgery-only patients (HR = 2.41, 95% CI = 1.67 to 3.49, P &lt; 0.01).ConclusionHigh RDW was associated with worse OS and DFS. Therefore, RDW was a simple predictive factor for the prognosis of BC patients.

As an anaerobic butyrate-producing bacterium, Clostridium cellulovorans can secrete a variety of extracellular enzymes to degrade plant-based cellulose. However, with glucose as the carbon source, it still secretes a large amount of protein in the broth. The metabolism and regulation are obscure and need to be further studied. Hence, in this study, C. cellulovorans was used to conduct fed-batch fermentation of glucose and microcrystalline at pH 7.0 to produce a higher level of butyrate in the bioreactor. It produced 16.8 mM lactate, 22.3 mM acetate, and 132.7 mM butyrate in 72 h during glucose fermentation. In contrast, it produced only 11.5 mM acetate and 93.9 mM butyrate and took 192 h to complete the fermentation with cellulose as the carbon source. Furthermore, there was no lactate detected in the broth. The analysis of carbon source balance and redox balance showed that 57% of the glucose was consumed to form acids in glucose fermentation, while only 47% of the cellulose was used for acid generation in the cellulose fermentation. Meanwhile, a large amount of protein was detected in the fermentation broth in both glucose (0.9 ± 0.1 g/L) and cellulose (1.1 ± 0.2 g/L) fermentation. These results showed that protein was also a main product. C. cellulovorans metabolized glucose to generate intermediate metabolites and reducing powers (NADH and Fdred), then protein and acid synthesis consumed this reducing power to maintain the carbon source balance and redox balance in the cell metabolism. The results of comparative transcriptomics and comparative proteomics also supported the above conclusion. The method of studying the protein during Clostridium species fermentation provides a new perspective for further study on metabolic regulation.

Decisive for solving food security problems in Ukraine while preserving and restoring the ecology of the environment should be an intensive method of management, i.e. the orientation of economic entities of their own activities on the innovative type of development, active use of scientific and technical developments and implementation of modern agricultural innovations. In its turn, the qualitative and quantitative indicators of crop production of protected soil depend on the technical condition of technological equipment.
The purpose of the work is research and analysis of existing power plants for ultraviolet disinfection of recirculating nutrient solution in systems of automatic hydroponic irrigation of crops in a protected soil, as well as elucidation of the impact of filtration and disinfection of nutrient solution on the presence of microorganisms when reusing plants in systems. The paper investigates the ways to improve the operation of power plants for ultraviolet disinfection of recirculating nutrient solution in the cultivation of crop products of protected soil. It provides the value of the required radiation dose for 90% disinfection of the recirculation solution from various bacteria, viruses and fungal spores and the dependence of bactericidal efficiency on the wavelength of light. Ultraviolet rays with a length from 200 to 280 nm (UV-C range) have the most pronounced bactericidal effect. Research in this area has shown that the optimal wavelength for irradiation is 253.7 nm. As a result of such irradiation, microorganisms die or lose their ability to reproduce. It has been proven that the classical layout scheme of power plants for ultraviolet disinfection of the recirculation solution is inefficient, because it does not rid the recirculation solution of turbidity and the presence of iron and does not guarantee high efficiency of the ultraviolet disinfection plants. The paper describes the method of carbonate precipitation of metal ions, which is based on the formation of insoluble metal compounds as a result of treatment of an aqueous solution with carbonates or bicarbonates of alkali metals. Prospects for further research are the development of methods and tools to improve the operation of power plants for ultraviolet disinfection of recirculating nutrient solution in the cultivation of crop products of protected soil.
ECOLOGICAL WATER QUALITY
Authors: Semeniuk N. 
Published: March 2023

Water quality – is a description of water’s chemical and biological composition and physical properties, which characterize it as an abiotic component of aquatic ecosystem and determine its suitability for specific consumption purposes.
Ecological water quality (environmental water quality) – refers to the ecological well-being of an aquatic ecosystem, with the main focus on protection of the aquatic environment and human life and health. It comprises a complex of physical, chemical, biological and other parameters reflecting specific features of abiotic and biotic components of aquatic ecosystems.
The requirements for physical, chemical and biological properties of water are set in the water quality standards, which may be developed by particular countries or introduced by international organizations.
Ecological water quality depends upon natural and human factors. Natural factors are in their turn divided into abiotic (for example, geological, meteorological, hydrological) and biotic (for example, the ratio of primary production and organic matter destruction). The main human factors affecting water quality include artificial modification of aquatic ecosystems’ hydrological conditions and their pollution with diverse chemical compounds.
There are a lot of approaches to ecological water quality assessment according to both abiotic (physical and chemical) and biological parameters. Physical and chemical methods take into account such parameters as water transparency, suspended particulate matter concentration (turbidity), ion composition, water hardness, total dissolved salts content, nutrients and organic matter content, dissolved gases concentration, pH. Biological methods are based upon assessing the living organisms’ (biological indicators’) response to mineral and organic substances, present in water. Various living organisms can be used as biological indicators: algae, in particular – diatoms, higher aquatic plants, different species of aquatic invertebrates and fishes. While physical and chemical methods characterize water quality at the moment of sampling, biological methods provide an integral picture of water quality for a certain time period. Besides, biological methods are more informative, because they reflect the aquatic ecosystem’s response to pollution.
On the whole, the most reliable data on ecological water quality can be obtained by combining physical, chemical and biological methods.

Introducción: el sobrepeso y la obesidad son enfermedades crónicas no transmisibles (ECNT) que en la actualidad poseen dimensiones pandémicas y se constituyen en importantes factores de riesgo cardiometabólicos para el desarrollo de otras ECNT.
Objetivos: estimar la prevalencia de adiposidad corporal y riesgo cardiovascular mediante los índices IMC, ICC, ICA, IPM y PA y, a su vez, explorar la asociación de tales índices con información sociodemográfica, calidad de la dieta e inactividad física.
Métodos: este fue un estudio de corte transversal de prevalencia realizado en 971 adultos de ambos sexos, provenientes del área urbana de Neiva, desde junio de 2018 a junio de 2019. Los profesionales de la salud realizaron antropometría para calcular los índices anteriormente mencionados empleando protocolos estandarizados. Se utilizaron puntos de corte validados para la población latinoamericana y colombiana para la clasificación en normopeso, sobrepeso, obesidad, obesidad abdominal y riesgo cardiovascular.
Resultados: se registraron las siguientes prevalencias: 56,5 % de exceso de peso (39,5 % de sobrepeso y 17 % de obesidad), 48 % de obesidad abdominal, 41,1 % de normopeso, 2,4 % de bajo peso, 68,5 % de riesgo cardiovascular (43 % de riesgo cardiovascular alto y 21,7 % de riesgo cardiovascular muy alto), 63,8 % de calidad regular y mala de la dieta y 57 % de inactividad física. Los índices anteriormente mencionados se asociaron con aumento de la edad, sexo masculino, aumento de la adiposidad corporal, calidad de la dieta e inactividad física.
Conclusiones: Las altas prevalencias para exceso de peso, sobrepeso, obesidad y riesgo cardiovascular observadas en adultos de Neiva se deben en parte a la alta proporción de dieta regular y de mala calidad e inactividad física.

Authors: Lyutikov A. A. 
Published: March 2023

The goal of the research was to study the viability of the offspring of the Coregonus muksun obtained from eggs inseminated at different time (-from 0 to 220 min) after collection.Classical fish breeding methods were used in the work: eggs was inseminated by dry method, incubation was carried out in sieves and modified Weiss devices with a volume of 1 l, juveniles were grown in 60 liter pools with a stocking density of 150 ind./pool, artificial diet and artemia nauplii served as food.Such studies in fish breeding practice are carried out for the first time, which determines their novelty.As a result of the research, an almost linear dependence of the survival rate of the offspring of muksun on the time of insemination of ovulated eggs was established with a very high degree of approximation reliability (R2) for embryos 0,906, larvae 0,846. The best survival rate of embryos and larvae was obtained in experimental variants in which eggs were inseminated in the first hour after collection. The proportion of live eggs at the end of incubation and larvae after 38 days of rearing was 57,5-58,9% and 78-84%, respectively. The survival rate of embryos and larvae in the experimental variants in which eggs were inseminated 80-100 minutes from the moment of collection were in the range of 40,1-42,2% and 49,4-50,1%, respectively; for 120-160 minutes 9,4-15,3% and 45,3-47,6%; for 180-220 min the survival rate of caviar did not exceed 5,0%, larvae- 45,6%.The practical significance of the work lies in determining the optimal period between the collection and insemination of eggs with the least risk to the viability of the offspring, which is of great importance in works on the artificial reproduction and cultivation of valuable fish species.

The aim: to study the amount of mercury found in muscle tissue and liver of the main commercial fish species of the Barents Sea.Research material was comprised of fish samples collected during the expeditions of “PINRO” named after Knipovich in the Barents Sea in 2009-2020. The study was based on muscle and liver samples taken from cod, haddock, long rough dab, Greenland halibut, plaice and spotted catfish. Over 1500 samples were analyzed. Novelty: for the first time a comparative analysis of Hg concentration in six commercial fish species of the Barents Sea was run and background readings were provided using such a big amount of data.Methods used: the total content of Hg in fish samples was measured using Shimadzu (Japan) Cold Vapor Atomic Absorption Spectrophotometer (CVAAS). Statistical data processing and charting were done using MS Excel and application software package of Statistica 13.Results: it was shown that the mean amount of Hg in muscle and liver of the studied fish was below the maximum concentration of 0.5 pg/g of wet weight acceptable by sanitary standards. Content of Hg in liver was two times higher than in muscle. No evidence of anthropogenic contamination of the studied species by mercury was found. The total content of Hg in muscle and especially in liver demonstrated a considerable variability, which is probably linked to seasonal changes in the diet. There might be other factors influencing the mercury concentration, such as taxonomic affiliation, regional peculiarities, physiological state, and fattiness.Practical significance: the acquired results were used to determine whether the commercial fishes meet the sanitary standards used in Russia.

Purpose: To find out the main parameters of the life cycle and the reproductive contribution of females depending on the age of their puberty.Method: Analysis of metal tagging in fur seal pups and tag return obtained by reading tags on live fur seals using optical instruments. Reading marks was carried out in 1982-2014 during the harem period on the Central site of the Northern rookery (Bering Island).Novelty: For the first time, data have been obtained on the reproductive contribution of female fur seals during the life cycle in relation to their age of puberty.Results: The birth of puppies in early maturing (at 2-3 years old) females is shifted to an earlier age, their life cycle is shorter, natural loss after the first fertilization is higher, they miss more breeding seasons during the life cycle. During the life cycle, early maturing females give birth to about 40% of the total number of puppies born by tagged females, and most of them (31%) are under the age of 8 years. Medium maturing (at 4-5 years old) females give birth to almost the same number of puppies (39.7%), however, the proportion of puppies born in these females is distributed more evenly over the life cycle. In late-maturing (at 6-7 years old) females and females entering the rookery at the age of 8+ years, the reproductive contribution is lower - they give birth to 13.4% and 6.3% of puppies, respectively, and the age at which puppies are born is higher - mostly 11 years and older.
