Published: September 2022

In this study, the main elements that can make up a Natural Treatment System for Wastewater (NTSW), its most important parameters and properties of operation and design, have been analyzed, as well as the environmental problems derived from the generation of large amounts of slurry. The objective of this paper is to propose a methodology to improve the operation of these systems, associated with small and medium-sized livestock farms, in insular and isolated systems such as the Canary Islands. An Integrated and Resilient System (IRS) for monitoring and measuring operational variables quasi-continuous and in situ is proposed. Low-cost technology and open source hardware are employed, as well as application of the IoT (Internet of Things) strategies to share and analyze the information collected in the cloud. In view of the high degree of resilience and the simplicity of this type of technology, as well as its low cost, it is concluded that it is feasible to create a measurement system with these characteristics that can be used for NTSW parameterization, and other purposes. Satisfactory results were obtained for several parameters (ambient temperature, relative humidity, UV radiation, atmospheric pressure). It is presented as a novel proposal based mainly on low-cost technology and free software with which to improve the NTSW operation process.

Monitoring vegetation growth and exploring the driving force behind it is very important for the study of global climate change and ecological environmental protection. Based on Normalized Difference Vegetation Index (NDVI) data from Moderate-Resolution Imaging Spectroradiometer (MODIS), meteorological and nighttime lights data from 2001 to 2020, this study uses the Theil–Sen slope test, Mann–Kendall significance test, Rescaled Range Analysis and partial correlation analysis to investigate the evolution of NDVI in the Minjiang River Basin, China, from three aspects: the spatial-temporal variation characteristics and future trend prediction of NDVI, the variation of climate and human activities in the basin, and the influences of different driving forces on NDVI. The results show that the average NDVI in the growing season was 0.60 in the Minjiang River Basin in the past twenty years, with a growth rate of 0.002/a. The area with high NDVI growth accounts for 66.02%, mainly distributed in the southeast, the central and the northern low-altitude areas of the basin. Combined with the Hurst index, the NDVI in the Minjiang River Basin exhibits an anti-sustainable tendency, with 63.22% of the area changing from improvement to degradation in the future. Meanwhile, the spatial differentiation of NDVI in the Minjiang River Basin is mainly affected by topography and climate factors, followed by human activities. This study not only provides scientific guidelines for the vegetation restoration, soil and water conservation and sustainable development of the Minjiang River Basin, but also provides a scientific basis for making informed decisions on ecological protection under the impacts of climate change and human activities.
Modification of Disinfection Process at a Local Water Treatment Plant—Skawina (Poland)
Authors: Winid Bogumiła , Muszański Robert , Wilkosz Jan
Published: September 2022

This paper summarizes studies undertaken at a water treatment plant in Skawina (WTP Skawina) where the disinfection process was modified by introducing a mobile ozonation system. The application of a small-size, fully-automated ozonation installation only slightly complicates the water treatment process, without the need to redesign the water treatment line, and with relatively low investment costs. The aim of this study was to analyze whether the change of the disinfection method affects the final water quality. The investigated water samples were treated in the mobile ozonation system using a disinfection process with only sodium hypochlorite. Treated water was of excellent quality, and seasonal variations in raw water parameters (variable organic matter contents) did not result in elevated trihalomethanes (THM) and bromate concentrations. Despite the trace amounts of bromides in the water prior to treatment, the water in the municipal drinking water system did not contain determinable amounts of bromates. The bromine concentrations in the treated water supplied to the water distribution system were higher than in raw water, which could be attributable to the presence of bromine as a contaminant in sodium hypochlorite (the disinfection agent). Water quality tests carried out by the water treatment plant (WTP) and by the State Sanitary Inspectorate after the modification of the process line confirmed the high quality of water in the distribution network after the change of disinfection method.
Phosphorus Transport in the Mississippi Delta: Associations to Surface and Groundwater Interactions
Authors: Justus Billy
Published: September 2022

Groundwater (GW) in the Mississippi Delta has some of the highest phosphorus (P) concentrations measured in the U.S. Chemical data collected from GW and surface water (SW) sites were compared to understand factors affecting P concentrations. Spatial instability in Delta GWs indicates that P sources vary. High P measurements in shallow wells near rivers, in shallow nested wells compared to deeper nested wells, and P fluctuations in wells over time suggest that the land surface may be a greater source of P in shallow groundwater than natural geological deposits. Widespread reducing conditions in shallow GW, long-term P applications to the land surface, and shallow wells being proximal to streams are possible covarying explanatory variables. Potential SW to GW pathways of P include leaching and preferential flow paths; however, GW interactions with SW via irrigation, although unnatural, can result in P deposition on soils and later transport to SW or GW. GW tracer data indicate that irrigation return flows can exceed natural baseflow discharge to some streams in late summer. Studies are needed to confirm the degree that P is mobilized from soils and bed sediment to shallow GW and to determine how declines in GW levels resulting from irrigation affect ecological services in SW.

Climate change, urbanization, and population growth, particularly in urban areas such as Acapulco, Mexico, put pressure on water availability, where although surrounded by water, the inhabitants lack enough good-quality water, especially in the rainy season. In addition, water scarcity, socioeconomic factors, and infrastructure problems limit the satisfaction of water demand in this context, e.g., operational issues in the water treatment plants and problems in the distribution network caused by hurricanes. The objectives of this research were: (i) to determine the rainwater quality in Acapulco, Mexico; (ii) to propose a domestic water efficiency retrofit (WER) design implementing a rainwater harvesting system (RWHS); and (iii) to determine the RWHS efficiency in terms of economic savings, considering rainwater’s social acceptance for domestic consumptive uses. The WER design was developed in an SFH in Acapulco, Mexico. The RWHS catchment surface area was 29 m2. The device comprises a first-rain separator (20 L) and a storage tank (1200 L). The rainwater harvesting potential (RWHP) was evaluated during the 2020 and 2021 rainy seasons, whereas the harvested rainwater quality (HRWQ) was analyzed in samples from 2021. Alkalinity, pH, electrical conductivity, total dissolved solids, chlorides, nitrates, sulfates, and heavy metals and potentially toxic metalloids were analyzed. Additionally, 168 surveys were applied to SFH owners to evaluate WER acceptance. Results showed that the RWHP was ca. 44 and 21 L/m2 in 2020 and 2021, respectively. All the rainwater quality parameters met the World Health Organization guidelines for consumptive uses except for drinking water. The perception study showed a 95% willingness to adopt the WER. Due to the RWHP and the HRWQ, the WER of SFHs is a promising solution to address Acapulco hydric stress under the nature-based solutions approach.

Published: September 2022

Water scarcity has become a major impediment to economic development, and a scientifically sound water allocation plan is essential to alleviate water scarcity. An opportunity constraint approach is introduced to optimise the uncertainty of the minimum regional development level under five hydrological scenarios, and an interval-fuzzy two-stage chance-constraint model (IFTSC) is constructed to improve the reliability of the model results. The correlation of each stochastic parameter in the IFTSC model with the water allocation results and the economic benefits of the Tingjiang River basin is analysed by the Pearson correlation coefficient method. Simulation results from the IFTSC model show a downward trend in overall water scarcity and an upward trend in overall economic benefits in the Tingjiang River basin. Taking the dry water scenario as an example, the water shortage in the industrial sector decreases by 9.7%, and the overall economic benefits of the Tingjiang River basin increase by 41.58 × 108 CNY. The results of the correlation analysis based on Pearson’s correlation coefficient show that water allocation is strongly positively correlated with variables such as water price and regional minimum development requirements, and economic efficiency is strongly positively correlated with unit scale output value and losses caused by water shortage. This paper provides constructive suggestions and guiding directions for the rational allocation of water resources in the Tingjiang River basin through a detailed analysis of the results and identification of the main stochastic parameters in the water allocation process.

Published: September 2022

Abundance–Biomass Comparison (ABC) models, first described for marine benthic macrofauna, have been applied successfully to other marine and terrestrial/freshwater fauna but never to ecotonal communities. In particular, to our knowledge, ABC models have not been applied to hyporheic communities. This study represents the first application of ABC models to hyporheic assemblages. We aimed at testing the effectiveness of ABC models in describing the perturbation of hyporheic communities subjected to an existing/known disturbance. To this end, we applied the models to the hyporheic community of an Apennine creek, where the hyporheic waters of the upstream stretch were uncontaminated, whereas those of the downstream stretch were contaminated by ammonium. We also tested separated models for the summer and winter periods to account for potential variability due to season. ABC models provided a satisfactory description of the hyporheic community changes due to ammonium by showing the abundance dominance curve overlying that of the biomass in the downstream stretch contrarily to what was observed in the upstream stretch. However, ABC models did not highlight any significant seasonal effects. Our results showed that ABC models have the potential to be used as assessment tools for ecological quality of hyporheic zones in temperate regions.
Micro-Climate Computed Machine and Deep Learning Models for Prediction of Surface Water Temperature Using Satellite Data in Mundan Water Reservoir
Authors: Mukonza Sabastian Simbarashe , Chiang Jie-Lun
Published: September 2022

Water temperature is an important indicator of water quality for surface water resources because it impacts solubility of dissolved gases in water, affects metabolic rates of aquatic inhabitants, such as fish and harmful algal blooms (HABs), and determines the fate of water resident biogeochemical nutrients. Furthermore, global warming is causing a widespread rise in temperature levels in water sources on a global scale, threatening clean drinking water supplies. Therefore, it is key to increase the frequency of spatio-monitoring for surface water temperature (SWT). However, there is a lack of comprehensive SWT monitoring datasets because current methods for monitoring SWT are costly, time consuming, and not standardized. The research objective of this study was to estimate SWT using data from the Landsat-8 (L8) and Sentinel-3 (S3) satellites. To do this, we used machine learning techniques, such as Support Vector Regression (SVR), Gaussian Process Regression (GPR), simple neural network (ANN), and deep learning techniques (Long Short Term Memory, LSTM, and Convolutional Long Short Term Memory, 1D ConvLSTM). Using deep and machine learning techniques to regress satellite data to estimate SWT presents a number of challenges, including prediction uncertainty, over- or under-estimation of measured values, and significant variation in the final estimated data. The performance of the L8 ConvLSTM model was superior to all other methods (R2 of 0.93 RMSE of 0.16 °C, and bias of 0.01 °C). The factors that had a significant effect on the model’s accuracy performance were identified and quantified using a two-factor analysis of variance (ANOVA) analysis. The results demonstrate that the main effects and interaction of the type of machine/deep learning (ML/DL) model and the type of satellite have statistically significant effects on the performances of the different models. The test statistics are as follows: (satellite type main effect p *** ≤ 0.05, Ftest = 15.4478), (type of ML/DL main effect p *** ≤ 0.05, Ftest = 17.4607) and (interaction, satellite type × type of ML/DL p ** ≤ 0.05, Ftest = 3.5325), respectively. The models were successfully deployed to enable satellite remote sensing monitoring of SWT for the reservoir, which will help to resolve the limitations of the conventional sampling and laboratory techniques.

Pesticides have great potential to contaminate resources of drinking water by percolating and leaching, when applied in the agriculture sector as well as in domestic region. Activated carbon (AC) and Biochar (BCH) were used for adsorption in a fixed-bed column system. Both of the adsorbent-packed columns indicated an increase in the breakthrough time for atrazine from 3350 to 5800 min and 3200 to 5700 min, chlorothalanil 3200–5600 min and 3150–5550 min, β-endosulfan 3050–5400 min and 2950–5400 min, and α-endosulfan 2900–5200 min and 2850–5200 min with bed heights from 10 cm to 15 cm, respectively. Similarly, when flow rate increased from 0.5 to 1.5 mL min−1 and contaminant concentration from 50–100 µg L−1, it resulted in a decrease in exhaust time. The models of Yoon–Nelson (R2 = 0.9427) and Thomas (R2 = 0.9921) describe the process of adsorption to be best well-under optimal conditions. Both the adsorbents would be efficiently utilized as the best adsorbents to remediate pesticide-contaminated water under optimal conditions. Pesticides adsorption onto adsorbents followed the order of atrazine > chlorothalanil > β-endosulfan > α-endosulfan.

Published: September 2022

The research was carried out on the flow-through Lake Mielenko (7.8 ha; 1.9 m), which also acts as a stormwater receiver. In 2015, a disposal for road salts was created in the lake’s catchment area. As a result of the inflow of salt-contaminated stormwater, there was a significant increase in the concentration of calcium (57 mg Ca/L), chloride (220 mg Cl/L) and electrolytic conductivity (790 µS/cm). Increased calcium concentrations in lake waters changed their hardness from low to medium-hard. The ecological effect of the change in hydrochemical conditions in Lake Mielenko is the Potamogeton crispus that grows abundantly in this reservoir, which prefer calcium-rich water. The overall aesthetics of the lake have deteriorated significantly, and the availability of water for recreation has also been limited.

Published: September 2022

The use of water safety plans (WSPs) has been recommended by the World Health Organization (WHO) since 2004 as a highly effective means of improving water safety management. Experience with the implementation of WSPs is increasing worldwide, but there is no unified or standardized methodology for how the verification of a WSP should be conducted. In this article, we present a thorough evaluation of a specific WSP five years after its initial implementation. We reviewed the risk assessment methodology used by a water utility in Salta, Argentina, and assessed the implementation of control measures. To objectively evaluate the effectiveness of the WSP, we evaluated water quality parameters and customer complaints using a time-series analysis. We show that although some control measures were implemented, and a reduction in risk values was observed, it was not possible to improve long-standing problems in the water supply of the city of Salta, such as the number of consumer complaints or high turbidity levels in the water during the rainy season. We discuss the role of rigorous scientific assessments and the importance of legislation and regulatory bodies in implementing the WSP.

Published: September 2022

The rapid development of the resin industry has led to a large amount of high-concentration resin production wastewater, which has created serious water pollution problems while limiting the development of related enterprises. In this study, a combined pretreatment hydrolysis acidification/two-stage anaerobic oxic (AO) process for high-concentration resin production wastewater was constructed, and the effect of operation time on the treatment efficiency of the hydrolysis acidification and the two-stage AO unit was investigated using chemical oxygen demand (COD), total nitrogen (TN), and NH3-H (ammonia nitrogen) as indicators. The effect of operation time on the treatment efficiency of the hydrolysis acidification and the two-stage AO unit was investigated. Results showed that the pretreatment of “alkaline digestion + ozone oxidation” could effectively remove volatile phenols and phenolic organic pollutants from the wastewater. The average removal rates of COD, TN, and NH3-H (ammonia nitrogen) of resin production were 91.96%, 85.35%, and 85.67%, respectively. The average concentrations of final biochemical effluent were 404.7, 21.4, and 11.4 mg/L, respectively.

One of the important issues of the modern period of animal husbandry development is the breeding of competitive breeds of farm animals that can quickly and eff ectively respond to the improvement of existing technologies and at the same time be widely their demand abroad. In order to perform such tasks of course it is required from scientists and livestock farmers to carefully and professionally approach the solution of this problem. Modern practice of the state and development of animal husbandry shows that non-compliance with the methodology of creating new breeding achievements leads to the fact that breeds and types are bred in a short period of time, which does not allow completing the basic requirements for testing new breeds and types such as uniformity, distinctiveness and stability. Such an approach to a very important problem of the development of animal husbandry can lead to the degradation of existing, including newly bred breeds. In this regard, the authors of the article pay special attention to the observance of the classical methodology for breeding new and improving existing animal breeds, and the effective use of scientific developments of scientists through their wide popularization to improve and improve the quality of products and in general the competitiveness of animal husbandry in our country. Currently, it is important to develop methods and techniques for breeding and technological increase in productivity and improvement of animals capable of producing the maximum amount of high-quality products at the lowest prime-cost. The analysis of patent and scientifi c literature on the developments of scientists shows that most of them have not been implemented and are not being introduced into production, despite the significant costs of conducting scientific experiments and, in general, the long, strenuous and professional work of a large team of scientists and farmers.

Poultry farming is the most dynamically developing branch of animal husbandry, from which we receive such valuable products as eggs and meat. The main costs in the production of livestock products, including poultry, fall on feed, therefore increasing their digestibility, the use of compound feed from cheap domestic raw materials without reducing the nutritional value while fully providing poultry with the substances necessary for normal functioning is one of the ways to reduce the primecost. This is possible due to the use of new feed additives including biologically active substances, including enzymes that increase the digestibility of nutrients. The purpose of the work was to study the possibility of using the biologically active additive Ares in the production of broiler meat, including as a substitute for antibiotics. It was found as a result of the conducted studies, that the chicks from the 2nd experimental group received the drug Ares in the amount of 0,6 g/kg of compound feed had the greatest live weight. Lower indicators occurred in broiler chickens of the 1st and 2nd experimental groups. However, they exceeded the normative indicators of the cross Coob 500 and the results of the control group by live weight at the age of 36 days. According to the growth periods, broiler chickens grew unevenly and diff ered signifi cantly among themselves by groups. So, in the fi rst 7 days of the rearing of the group, there was almost no diff erence in the growth rate. Only broiler chickens of the 1st experimental group achieved the standard growth indicators, the diff erence in other groups compared with the standard was 7,6 and 33,1 g or 3,5-15,3 %. The superiority of broiler chickens of the 1st experimental group over the other groups was 23,5; 33,1 and 8,6 g or 11,0; 16,0 and 4,0 %. At the age of 17 days broiler chickens of the 2nd experimental and control groups had a large live weight, with some lag of the 1st and 3rd experimental groups. At the end of rearing all experimental groups outperformed broiler chickens of the control group by 39,4–294,9 g or 2,0–14,0 %. Thus, the use of biologically active feed additive Ares allows us to get high results in the rearing of broiler chickens.

Published: September 2022

Background

General practice plays a critical role in the prevention, diagnosis, management, and survivorship care of patients with cancer. Mapping research outputs over time provides valuable insights into the evolving role of general practice in cancer care.

Aim

To describe and compare the distribution of cancer in general practice research publications by country, cancer type, area of the cancer continuum, author sex, and journal impact factor.

Design and setting

A bibliometric analysis using a systematic approach to identify publications.

Method

MEDLINE and Embase databases were searched for studies published between 2013 and 2019, which reported on cancer in general practice. Included studies were mapped to the cancer continuum framework. Descriptive statistics were used to present data from the included studies.

Results

A total of 2798 publications were included from 714 journals, spanning 79 countries. The publication rate remained stable over this period. Overall, the US produced the most publications (n= 886, 31.7%), although, per general population capita, Denmark produced nearly 10 times more publications than the US (20.0 publications per million compared with 2.7 publications per million). Research across the cancer continuum varied by country, but, overall, most studies focused on cancer screening, diagnosis, and survivorship. More than half of included studies used observational study designs (n= 1523, 54.4%). Females made up 66.5% (n= 1304) of first authors, but only 47.0% (n= 927) of last authors.

Conclusion

Cancer in general practice is a stable field where research is predominantly observational. There is geographical variation in the focus of cancer in general practice research, which may reflect different priorities and levels of investment between countries. Overall, these results support future consideration of how to improve under-represented research areas and the design, conduct, and translation of interventional research.

Authors: ABUSHAREKH Mohammed , KAKAR Muhammad Hamayun , ÖZCAN Emin Evren
Published: September 2022

Objective: Cardiac resynchronization therapy (CRT) is commonly used in patients with heart failure (HF) along with left ventricular mechanic and electrical dyssencrony. Left ventricular epicardial pacing in CRT patients changes the normal myocardial activation and increases the transmural dispersion of repolarization. We aimed to investigate the impact of CRT on repolarization parameters and reveal its consequences on arrhythmic events.

Materials and Methods: The study consisted of 54 patients treated with CRT. Repolarization parameters; QT, T peak-to-T end and JT, Tpe/QT, QT dispersion and Tpe dispersion were measured. The patients were also investigated in two subgroups according to the presence of ventricular arrhythmias at the end of follow-up. Subgroups were compared in terms of repolarization parameters.

Results The change in repolarization parameters according to baseline values were also compared in the whole group.In the whole study group, all of the repolarization parameters significantly increased in the acute phase. In the chronic phase, these abnormalities were significantly diminished. The comparison of the two subgroups did not show any significant difference in respect of repolarization parameters.

Conclusion: Epicardial pacing prolongs myocardial repolarization time and increases transmural dispersion of repolarization. However, these abnormalities were transient and were not associated with ventricular arrhythmias.

Dosyalarından PH teşhisi olan 119 hasta çalışmaya dahil edilmiştir. Hastaların 1 dakikadaki göz kırpma sayıları ile takip bilgileri arasındaki ilişki için analizler gerçekleştirilmiştir.

Bulgular: Çalışmamıza katılan hastaların medyan yaşı 60 (52-69) olarak saptanmıştır. Katılımcılardan 41 tanesi (%35) kadındır. Grubumuzun spontan göz kırpma sıklığı 12 (6-25)/dk olarak ölçülmüştür. Göz kırpma sıklığı ikili lojistik regresyon analizlerinde, cinsiyet, hastalık süresi, hastalık klinik tipi ve l-dopa eşdeğer dozu ile beraber değerlendirildiğinde yaşla ilişkili bulunmuştur (p=0,021).

Sonuç: Sonuç olarak SGKS yaşla beraber düşüş göstermektedir. Parkinson hastalarında spontan göz kırpma sıklığı, cinsiyet, hastalık süresi, hastalık klinik tipi ve kullanılan dopaminerjik ilaçların l-dopa eşdeğer dozundan bağımsız olarak hastanın yaşı ile ilişkilidir. Bu nedenle SGKS, Parkinson hastalığı popülasyonunda kategorizasyon için güçlü bir biyobelirteç olarak kullanılamaz.

Giriş ve Amaç: Acil servise karın ağrısı ile başvuran hastalarda hastanede kalış süresini kısaltma ve mortalite, morbitide oranlarının azaltılmasında biyobelirteçlerin önemi büyüktür. Bu çalışmada karın ağrısı ile başvuran hastaların başvuru şikayetlerinin ciddiyetini belirleyebilmede platelet lenfosit oranı (PLO), nötrofil lenfosit oranının (NLO) önemi, hastalığın ciddiyeti arasındaki ilişkisi ve akut karını göstermede beyaz küre (WBC), PLO ve NLO’nun birbirine üstünlükleri değerlendirilmiştir.

Gereç ve Yöntemler: Bu çalışma 3. Basamak Üniversite Hastanesi Acil Tıp Kliniğine karın ağrısı şikayetiyle başvuran ve radyolojik olarak “akut batın” tanısı konan 200 hasta ve sağlıklı 100 kontrol grubu üzerinde prospektif olarak yapılmıştır.

Bulgular: Çalışmaya 200’ü hasta grubu, 100’ü kontrol grubu olmak üzere toplam 300 olgu dahil edilmiştir. Hasta ve kontrol grubunu ayırt etmede WBC duyarlılığı %79, özgüllüğü %79, PKD düzeyi %88,3, NKD düzeyi %65,3, NLO duyarlılığı %85, özgüllüğü %83, PKD düzeyi %90,9, NKD düzeyi %73,5 ve PLO duyarlılığı %69, özgüllüğü %68, PKD düzeyi %81,2, NKD düzeyi %52,3 olarak saptanmıştır. Olguların NLO değerleri ile WBC değerleri arasında pozitif yönde 0.510 düzeyinde, PLO değerleri ile WBC değerleri arasında pozitif yönde 0.115 düzeyinde istatistiksel olarak anlamlı ilişki olduğu saptanmıştır.

Sonuç: WBC, NLO ve PLO değerleri akut inflamasyonu gösteren belirteçlerden olup NLO’nun karın ağrısı ile başvuran hastalarda kritik hastaları tanımlamak, ileri görüntüleme sayısının azaltılmasını sağlamak ve primer sonlanımı öngörmede klinisyene yol göstereceğini düşünmekteyiz.
Obstrüktif Koroner Arter Hastalığı İle Serum 25-OH Vitamin D, Fetuin-A, Matrix Gla Protein Ve ADMA Düzeyleri Arasındaki İlişki
Authors: TAŞKIN Uğur , TIKIZ Hakan
Published: September 2022

Giriş ve Amaç: Bu çalışmada ateroskleroz etyolojisinde rol oynadığı ileri sürülen 25OH-vitamin D, Matrix Gla Protein (MGP), Fetuin-A, Asimetrik Dimetil Arjinin (ADMA) belirteçleri ile koroner arter hastalığı arasındaki ilişki araştırıldı.

Gereç ve Yöntemler: Bu amaçla çalışmaya koroner arter hastalığı ön tanısı ile koroner anjiyografi işlemi uygulanmış olan ve normal koroner arter saptanan 40 olgu ile, en az bir koroner arterinde %70 ve üzerinde darlık saptanan 40 olgu olmak üzere toplam 80 olgu dahil edildi.

Bulgular: Kan MGP düzeyleri koroner arter hastalığı olan grupta kontrol grubuna kıyasla anlamlı olarak yüksek olarak gözlenirken (sırasıyla 2082,79±329,75 pg/ml ve 1853,42±285,82 pg/ml, p=0,001), Fetuin-A düzeylerinin kontrol grubunda, koroner arter hastalığı grubuna kıyasla anlamlı derecede düşük olduğu gözlendi (sırasıyla 60,54±28,61 ng/ml ve 78,61±20,45 ng/ml, p=0,002). Her iki gruptaki hastaların %85’inde 25OH-vitamin D seviyeleri düşük düzeylerde izlenmekle beraber, her iki grup arasında istatistiksel olarak anlamlı olarak fark saptanmadı (sırasıyla 20,27±12,65 ng/ml ve 20,64±7,32 ng/ml, p=0,875). Kan ADMA seviyeleri incelendiğinde ise yine gruplar arasında istatistiksel olarak anlamlı bir fark gözlenmedi (grup 1; 0,099±0,053 umol/l ve grup 2; 0,089±0,051 umol/l, p>0,05). Sonuç olarak; 25OH-vitamin D ve ADMA değerleri ile koroner arter hastalığı arasında anlamlı bir ilişki saptanmazken, MGP ve Fetuin-A'nın tıkayıcı koroner arter hastalığında belirteç olabileceği gözlendi.

Sonuç: Bizim çalışmamızda tıkayıcı koroner arter hastalığı tanısında MGP ve Fetuin-A biyobelirteçlerinin yol gösterici olduğu gözlenmiştir. Bu bulgular ışığında MGP ve Fetuin-A düzeylerinin koroner arter hastalığı tanısında kullanımının değerlendirilmesi için benzer altyapılı ve daha geniş popülasyonlarla yapılacak yeni çalışmalara ihtiyaç vardır.

Senam hamil merupakan terapi latihan gerak yang diberikan pada ibu hamil untuk mempersiapkan dirinya baik fisik maupun mental dalam menghadapi persalinan.Ibu hamil sangat membutuhkan tubuh yang sehat dan bugar. Senam hamil sangat diperlukan oleh setiap ibu hamil, karena senam hamil dapat membuat tubuh yang bugar dan sehat, dan dapat membuat ibu hamil tetap mampu menjalankan aktivitas sehari-hari, sehingga stres akibat rasa cemas menjelang persalinan akan dapat diminimalkan. Namun banyak ibu hamil yang tidak melakukan senam hamil.dikarenakan ragu-ragu dan takut akan kehamilannya jika melakukan senam hamil.Padahal senam hamil sangat penting dalam masa kehamilan, karena memperlancar proses persalinan.Latihan senam hamil yang dilakukan secara teratur baik ditempat latihan maupun di rumah dalam waktu senggang dapat menuntun ibu hamil ke arah persalinan yang fisiologis selama tidak ada keadaan patologis yang menyertai kehamilan.Ibu hamil yang melakukan senam hamil secara teratur selama masa kehamilannya dilaporkan dapat memberikan keuntungan pada saat persalinan yaitu pada masa kala aktif (kala II) menjadi lebih pendek, mencegah terjadinya letak sungsang dan mengurangi terjadinya kejadian sectio caesaria.
