Correlation Between Changes in NLR Value and RECIST among Lung Cancer Patients at Saiful Anwar Malang Hospital
Authors: Kristianto Fransiskus , Setyawan Ungky Agus , Erawati Dini Rachma
Published: January 2025

Background: In practice, clinicians use Response Evaluation Criteria in Solid Tumors (RECIST) to decide the progressivity of lung tumors. Besides RECIST, there is an inflammatory marker called Neutrophil to Lymphocyte Ratio (NLR), which has prognostic value in cancer patients. Many previous studies have shown that NLR can predict the prognosis because inflammation in cancer patients is part of the tumor progressivity.  Therefore, the changes in NLR value have the potency to be one of the ways to decide the progressivity of tumors in lung cancer patients.
Method: This cross-sectional study was conducted to see whether there is a correlation between RECIST and NLR in 95 lung cancer patients at Saiful Anwar Hospital whose data were taken from January 2022 to May 2023. The variable will be tested using the chi-square test to see the correlation and the logistic regression method to obtain the odds ratio.
Results: There is a significant correlation between changes in NLR and RECIST with P=0.041.  Through Logistic Regression Analysis, the value of the odds ratio is 2.46 (CI 95%=1.03-5.94).  In the group with progressive RECIST, the average NLR value after therapy was higher than the average NLR value after therapy in the non-progressive group.
Conclusion: This study concludes that changes in NLR value have the potency to help the determination process of lung cancer progressivity as RECIST does.

Published: January 2025

The purpose of the study is to conduct a comparative analysis of two methods for diagnosing eimeriosis in cattle and to identify the most accessible and effective of them. The spread of eimeriosis in on the territory of the training and experimental commercial dairy farm N3 Kuban was studied. When making a diagnosis, clinical signs in young and adult animals, epizootological data, as well as the results of laboratory studies of fecal samples were taken into account. In total, 215 faecal samples from Holstein cattle were examined. Fülleborn and McMaster methods were used for diagnosis. Determination of eimeria to species was carried out using the Krylov determinant. According to outpatient journals, seasonal and age-related predisposition to the disease was revealed. Of the more than 20 species of Eimeria described in cattle, the species responsible for the most pronounced manifestation of clinical signs with the phenolmenon of hemorrhagic diarrhea: E. Zuerni, E. Bovis, E. Ellipsoidalis prevail in this educational and experimental farm. It has been established that the McMaster method is the most effective and affordable for the diagnosis of eimeriosis in cattle. The age groups most vulnerable to this invasion were identified: the prevalence of invasion in calves of 1–2 months of age is 12 %; 2–4 months – 22; 4–6 months – 31 %. An analysis of the degree of manifestation of invasion was made, which showed that clinically pronounced coccidiosis, as the most economically costly form, manifests itself in 46 % of cases, while the subclinical form was detected in 54 % of the studied calves. As a result of a study of the consequences of a long-term illness of calves with eimeriosis in a subclinical form, it was concluded that there would be significant consequences in the future on the part of the gastrointestinal tract and other body systems. These factors reduce the degree of overall development and economic feasibility of keeping such calves due to a lack of muscle mass, reduced immunity and reduced milk production.

Published: January 2025

The purpose of research is to study the influence of weather conditions in the Tyumen Region on the percentage of dry matter in the green mass of late-ripening varieties of red clover during the harvesting period. Observations were carried out on the experimental field of the Research Institute of Agriculture of the Northern Trans-Urals – a branch of the Tyumen Scientific Center of the Siberian Branch of the Russian Academy of Sciences in 2015–2022 on plants of 12 late-ripening (single-cut) samples of red clover of the 1st year of use. Weather conditions in most years were warm with sufficient precipitation, dry conditions were observed only in 2021; the hydrothermal coefficient (HTC) of Selyaninov was 0.47–2.55. The date of resumption of vegetation was noted in the second decade of April, the cutting of green mass was carried out in the second decade of July. In 2015–2022 harvesting of green mass from varieties of red clover ranged from 17.9 to 62.5 t/ha, with a dry matter content in it from 20.4 to 37.1 % and a difference between the values by years from 0.8 to 13.3 %. There was a relationship between the value of the HTC and the ratio of fodder products in freshly harvested (green mass) and dry form (hay). With HTC values >2, the collection of green mass was 4.2–4.6 times higher than the yield of hay with HTC < 2, 3.0–3.4 times. The dry matter content of green mass under conditions of excessive moisture (HTC = 2.4–2.55) decreesed – 21.9–23.5 %, with a lack of moisture (HTC = 0.47–1.25) increased – 31.2–34.7 %, which was confirmed by a significant negative correlation (r = -0.753–0.965) between the dry matter content and the HTC for the season (April – July) for all varieties. The sum of active temperatures in April-May (r = 0.746–0.846 for 5 varieties) could also contribute to the increase in the dry matter content in the green mass, which indicated the importance of warmth during the spring regrowth.

At this time, computational thinking ability is very important because it can help humans in achieving success in the world of work and society is getting bigger. This preliminary study aims to identify and explore the computational thinking skills of junior high school students and the factors that influence them. The research method used was mixed methods by giving 3 description questions on linear function material that can measure computational thinking ability to 35 class IX students in one of the junior high schools in Sukabumi. The results showed that the highest score achieved by students was 91.67 while the lowest score was 16.67. The average score was 58.33 with 20 students above average and 15 students below average. The median test score was 58.33 with the modes being 44.44 and 61.11. After analyzing each student's answer, it was found that the computational thinking ability of junior high school students was at a low level. The test results stated that students were only capable of the problem decomposition and algorithm stages, not yet to the stages of pattern recognition and abstraction. Students tend to perform calculations directly after breaking down the problem into smaller parts and writing down sequential steps to solve the problem. This shows that mathematics learning in schools today is still lacking in directing students to computational thinking skills.

Published: January 2025

Traffic problems are often found in big cities or small towns, one of which is Pamekasan Regency. Traffic jams often occur at the intersection with no signal, the intersection of Jl. Mandala â€“ Jl. Raya Tlanakan Pamekasan City. Intersections are an integral part of all road systems. The performance of the intersection often decreases which has an impact on road users due to vehicle queues, decreased speed, decreased environmental quality and increased delays. The benchmarks for evaluating the performance of intersections are capacity, queuing opportunities, intersection delays and degrees of saturation. The results of the analysis of the performance of the intersection obtained a maximum capacity value (C) of 2257.83 pcu/hour not more than the basic capacity (Co = 2700 pcu/hour). This shows that the lowest capacity classification occurs on Thursday, December 8, 2022 at 18.00 â€“ 21.00 WIB, while the highest DS (Degree of Saturation) value is 0.63 and the largest intersection delay (D) is 19.17 sec/ SMP occurs on Thursday, December 8, 2022 at 06.00 â€“ 10.00 WIB. Based on these results it can be seen that the capacity at the intersection of Jl. Mandala â€“ Jl. Raya Tlanakan Pamekasan City is still feasible to accommodate the traffic volume, because it is smaller than the basic capacity of the intersection. To overcome the problem of congestion at intersections, generally during working hours or during peak hours, security and supervision from related parties are needed.

The term land subsidence denotes the collapse of a building due to compression and deformation of the soil layer beneath the building. Settlement will occur if a layer of soil is loaded, settlement is also influenced by the distribution of soft soil or clay found below the surface on alluvial plains. In this case, the West Sumatra-Riau Jorong Bancah Kenagarian Batu Balang road, Kabupaten Lima Puluh Kota, is one of the areas traversed for the construction of the West Sumatra-Riau cross road. This road is included in the category of primary local roads with a road width of 6 m. Currently, the physical condition of the West Sumatra-Riau Jorong Bancah Kenagarian Batu Balang road, Kabupaten Lima Puluh Kota, has been repaired and some has not been repaired. The road in Bancah includes the Payakumbuh â€“ Tanjung Pati ring road, which is used by the local community and trucks to speed up the road. Based on this, a study was carried out to determine the condition of the soil on the road. This research was conducted by taking samples at the research location and then determining the water content, specific gravity, density and finally the California Bearing Ratio (CBR). The average water content for undisturbed samples was found to be 30.98%. Based on the test results, it was found that the average soil density was 1.10 gr/cmÂ³, so it can be concluded that the soil tested was a type of clay. Furthermore, the results of testing the soil density obtained dry specific gravity, the maximum É¤d is 2.83 t/m and the optimum moisture content is 16%. The density obtained from the results of testing in the Civil Engineering Laboratory of STT Payakumbuh is the average soil density: 2.59 gr/cmÂ³ which is categorized as soft soil. The results of laboratory CBR testing found that the average CBR of soil was 5.27%. This shows that the land is not suitable for use for construction if the minimum standard is 6%.

Background: Pulmonary tuberculosis (TB) and bacterial pneumonia are respiratory infections with high morbidity and mortality rates. Despite having similar clinical symptoms and radiological findings, these conditions require different treatment approaches. Procalcitonin is a potential biomarker to differentiate these conditions, as its levels tend to increase in bacterial infections but not in TB. This study aims to compare procalcitonin levels in patients with pulmonary TB and bacterial pneumonia.
Methods: This research employed an observational analytic design with a cross-sectional approach conducted at Dr. Mohammad Hoesin General Hospital (RSMH), Palembang. The study subjects were patients with pulmonary TB and bacterial pneumonia who met the inclusion and exclusion criteria. Procalcitonin levels were measured using ELISA methods. Data were analyzed to determine differences in procalcitonin levels between the two groups.
Results: The study found that procalcitonin levels in bacterial pneumonia patients were significantly higher than those in pulmonary TB patients (p<0.05). These findings indicate that procalcitonin levels can serve as a diagnostic parameter to distinguish between the two conditions.
Conclusion: Procalcitonin levels can be a useful biomarker for differentiating pulmonary TB from bacterial pneumonia. This biomarker is expected to assist clinicians in making more accurate diagnoses and expediting clinical decision-making.

Published: January 2025

Introduction: Traumatic brain injury (TBI) often presents alongside extracranial injuries requiring surgical intervention. General anesthesia in such cases poses significant challenges, particularly in patients with concomitant pulmonary complications. This case report describes the successful use of ultrasound-guided ulnar nerve block combined with dexmedetomidine sedation for a patient with moderate TBI and pulmonary contusion undergoing open reduction and internal fixation (ORIF) of a left-hand finger fracture.
Case presentation: A 50-year-old male presented with moderate TBI, pulmonary contusion, and an open fracture of the fifth digit of his left hand following a motor vehicle accident. Due to the risks associated with general anesthesia, an ultrasound-guided ulnar nerve block was performed using levobupivacaine 0.375%. Dexmedetomidine was used as a sedative agent due to its neuroprotective properties and minimal respiratory depressant effects. The procedure was successful, with the patient maintaining stable hemodynamics and adequate sedation throughout the surgery.
Conclusion: This case highlights the feasibility and safety of ultrasound-guided peripheral nerve block combined with dexmedetomidine sedation as an alternative to general anesthesia in patients with TBI and pulmonary contusion. Dexmedetomidine's neuroprotective effects and minimal respiratory depression make it a valuable tool in managing such complex cases.

The selection of vocabulary learning strategies (VLS) is a pivotal action in the English teaching and learning process. This study aimed to explore what teachers perceive and experience in vocabulary instruction in higher education. A narrative approach was employed in this study. Using the purposive sampling technique under the criteria of a minimum of four years of experience as permanent English teachers and limited the area of study only to one of religious higher education in Central Kalimantan, five English teachers were enrolled as participants. Unstructured, open-ended interviews were used as the instrument for collecting the primary data. After collecting the stories, the data were reported and validated using triangulation. The results revealed that teachers believed that using a variety of learning strategies to engage learners to be interested in vocabulary instruction was useful. Then, the challenges both external and internal factors faced by teachers in vocabulary instruction could be handled by employing the strategies that fit the students’ characteristics, such as learning vocabulary through songs, games, and social media platforms such as TikTok, YouTube, Instagram, and so forth. Therefore, it can be drawn to the conclusion that teachers must always be creative and innovative in action by utilizing technology advancement. Besides, the use of differentiated instruction approach could be better employed by teachers for solutions to problems, particularly in facilitating diverse student characteristics. Next, the use of various modes of learning or multimodal sources can also help students in higher education to get very meaningful vocabulary learning.

Aim: Baijiu adulteration has always been a hot spot of social concern, especially high-temperature Daqu Baijiu, because of its better flavor quality and high value, it faces a challenge from illegal adulteration of high-grade Baijiu bottles with low-grade Baijiu.
Methods: A new ultraviolet-visible spectroscopy (UV-VIS) sensor method based on 2-(2-hydroxyphenyl) benzothiazole (HBT) combined with Zn2+ was constructed. The specific mechanism of light signal change was mainly based on the competitive coordination effect of pyrazines and other nitrogen-containing compounds in high-temperature Daqu Baijiu and small molecular probe HBT on Zn2+ and the excited state intramolecular proton transfer (ESIPT) mechanism of HBT itself.
Results: The random forest results showed that the prediction set classification accuracy was improved from 62.37% to 100%. The accuracy of the data driven-soft independent modelling of class analogies (DD-SIMCA) model was between 90% and 100%, indicating that the array sensor had a good recognition effect on the adulteration of the same aroma type of Baijiu. Twelve kinds of Maillard reaction products such as tetramethylpyrazine, 2,6-dimethylpyrazine, and furfural in Baijiu were predicted successfully, and the deviation between the real value and the predicted value was less than 1.8746% ± 1.4515%.
Conclusions: This method not only improves the specificity of spectral detection, and the amount of information extracted from Baijiu samples, but also the detection time is shortened to less than 3 min, and the accurate identification of high-temperature Daqu Baijiu with the same aroma type was realized. This method can provide reliable help for the rapid identification of high-temperature Daqu and other precious Baijiu, even traditional fermented food.

Introduction: The development and use of modified polyolefin films as packaging materials is a promising direction for the improvement of modern food packaging, particularly dairy products. By targeted modification, it is possible to create an "active package" that has a set of desired properties. For example, the packaging can contain substances with antimicrobial or antioxidant effects that are activated when the packaged product comes into contact with them.

Purpose: This study aims to investigate the effect of adding calcium carbonate to a polyethylene film and antioxidant dihydroquercetin on its sanitary and hygiene properties.

Materials and methods: The objects of research were samples of developed film filled with calcium carbonate (CaCO3) and dihydroquercetin (DKV), which were selected. The development and production of the materials was carried out on an experimental site using an SJ-28 laboratory extruder. Samples of film were produced using a pre-prepared super concentrate. Sanitary, chemical, and organoleptic tests were performed in accordance with TRTS 005/2011 “On Packaging Safety” and GOST 34174-2017, as well as instructions from the Ministry of Health, MI 880-71.

Results: Using the methodology of combining polymer bases, mineral and organic fillers in a melt, it was possible to produce a modified film packaging material. An algorithm for the technology was proposed and modes for obtaining samples with different contents of injected substances were worked out. Organoleptic and sanitary-chemical tests of the obtained samples confirmed their sanitary and hygiene safety at selected filler concentrations and extrusion conditions.

Conclusions: The data obtained on the production of filled modified films showed the technological suitability of the chosen method, mode, and component composition. Comprehensive organoleptic and chemical-sanitary tests have shown the absence of excessive odor and the lack of migration of low-molecular-weight substances and oxidation products in model media.

Published: January 2025

Introduction: Probiotic microorganisms are known to increase the biological value of foods, reduce cholesterol levels, positively affect the immune system, prevent intestinal infections and diarrhea associated with antibiotics, reduce symptoms of lactose intolerance, etc. These positive effects depend on the properties of the probiotic strain. The metabolic products of probiotic microorganisms are also capable of having a positive effect on the human body. The metabolic complexes secreted by probiotic bacteria are characterized by high digestibility and resistance to environmental conditions and can potentially be used along with probiotic microorganisms.

Purpose: To study. the possible effect of different concentrations of the postbiotic composition on enhancing the biological properties of the product, in particular, its ability to stimulate the growth of bifidobacteria.

Materials and Methods: As objects of research, a fermented milk product based on a probiotic association consisting of Lactococcus cremoris 241C, Lactocaseibacillus rhamnosus F, Propionibacterium shermanii E2, developed using a postbiotic complex (PC) in concentrations of 0.5 and 0.01%, was used. In the study of the ability to stimulate the growth of bifidobacteria, a strain of Bifidobacterium adolescentis MS–42 from the collection of FGANU «VNIMI» was used as a control culture. The studies were carried out on the GMC 2 medium and a probiotic fermented milk product developed on sterile skimmed milk. The effect of two PC concentrations (0.5 and 0.01%) on stimulating the growth of bifidobacteria in experimental samples after 8 and 24 hours of incubation was studied.

Results: The positive effect of PC at a concentration of 0.01% on the growth of bifidobacteria was confirmed. The absence of a stimulating effect of PC in a concentration of 0.5% may be due to inhibition by acetic acid - the final product

Conclusion: The data obtained allow us to confirm the increase in the biological effectiveness of a fermented milk product with a postbiotic complex in relation to stimulating the growth of bifidobacteria, and recommend it as an additive to the biotechnological system at a concentration of 0.01%.
