Abstract
In this article, the numerical and experimental free vibration analyses of PLA-based composite plates with different filling geometries were carried out. Firstly, the natural frequencies and modal shapes were obtained from finite element (FE) methods to characterize the vibration behavior of the plates. The obtained results were compared with experimental testing of the three-dimensional (3D) produced plates. In the comparison, it was seen that the finite element analysis and the experimental results were quite close to each other. It was also observed that the highest frequencies are measured by a triangle, then the grid and honeycomb. Moreover, higher frequencies and lower weights are possible with the triangle pattern fill. On the other hand, it is noted that the types of filling structures do not affect the modal shapes of the 3D plates. Thus, the results of this paper are of utmost importance for getting light structure and high frequencies.

OBJECTIVES
Examine family safety-reporting after implementing a parent–nurse–physician–leader coproduced, health literacy-informed, family safety-reporting intervention for hospitalized families of children with medical complexity.

METHODS
We implemented an English and Spanish mobile family-safety-reporting tool, staff and family education, and process for sharing comments with unit leaders on a dedicated inpatient complex care service at a pediatric hospital. Families shared safety concerns via predischarge surveys (baseline and intervention) and mobile tool (intervention). Three physicians with patient safety expertise classified events. We compared safety-reporting baseline (via survey) versus intervention (via survey and/or mobile tool) with generalized estimating equations and sub-analyzed data by COVID-19-era and educational attainment. We also compared mobile tool-detected event rates with hospital voluntary incident reporting.

RESULTS
232 baseline and 208 intervention parents participated (78.2% consented); 29.5% of baseline families versus 38.2% of intervention families reported safety concerns (P = .09). Adjusted odds ratio (95% CI) of families reporting safety concerns intervention versus baseline was 1.6 (1.0–2.6) overall, 2.6 (1.3–5.4) for those with &lt; college education, and 3.1 (1.3–7.3) in the COVID-19–era subgroup. Safety concerns reported via mobile tool (34.6% of enrolled parents) included 42 medical errors, 43 nonsafety-related quality issues, 11 hazards, and 4 other. 15% of mobile tool concerns were also detected with voluntary incident reporting.

CONCLUSIONS
Family safety-reporting was unchanged overall after implementing a mobile reporting tool, though reporting increased among families with lower educational attainment and during the COVID-19 pandemic. The tool identified many events not otherwise captured by staff-only voluntary incident reporting. Hospitals should proactively engage families in reporting to improve safety, quality, and equity.

AbstractIn 2023, a major European musical ensemble, the Belgrade Philharmonic Orchestra, celebrates its centennial. In the course of 100 years, this institution faced numerous obstacles, but thanks to the enthusiasm of great musicians, especially conductors, it has survived and laid the foundation for further musical and cultural development in Serbia. This article discusses the activity of the most important orchestral leaders (Stevan Hristić, Lovro von Matačić, Krešimir Baranović, Živojin Zdravković, Horst Förster, Vassily Sinaisky, Emil Tabakov, Uroš Lajovic, Dorian Wilson, Muhai Tang, Gabriel Feltz, Daniel Raiskin and Zubin Mehta), who have vastly contributed to or changed the course of the orchestra's development and left a big mark in its hundred-year-long history. In its centenary year, we will look back into the past, review the present, but also take a glimpse into the future the Belgrade Philharmonic Orchestra has already started to write for itself.
Low Free Thyroxine (FT4) in critically ill juvenile systemic lupus erythematosus: a diagnostic approach
Authors: Yuwono Elien , Wati Ketut Dewi Kumara , Arimbawa I Made 
Published: September 2024

Introduction: Thyroid dysfunction was frequent in systemic lupus erythematosus (SLE) patients, which may present as euthyroid, hypothyroid, or hyperthyroid states. Critical conditions have a higher chance of euthyroid sick syndrome due to alterations in the hypothalamic-pituitary-thyroid (HPA) axis. Renal impairment was associated with an increased risk of low FT4 due to proteinuria followed by thyroid loss.
Case Description: We reported one patient, a 15-year-old girl, who complained of shortness of breath and revealed acute respiratory distress syndrome, valve regurgitation, and pericardial effusion. She also felt joint pain over the leg and odor urination. Further evaluation showed non-scaring alopecia, pyuria, proteinuria >0.5 gram/24 hours, urinary cast, and acute kidney injury stage failure. ANA (IF) pattern: scattered with titer 1:100, ANA profile indicated Smith (Sm) antigen (+) and C3 108.3 mg/d, which fulfilled Systemic Lupus International Collaborating Clinics (SLICC) 2015 and European League Against Rheumatism (EULAR) 2019 criteria for SLE. On the fourth day of treatment, the patient had acute confusion, hypothermia, and sinus bradycardia, while the investigation of FT4 hormone was 0.45 ng/dL, TSH 2.39 uIu/ml, which revealed euthyroid sick syndrome. After treatment with a high dose of methylprednisolone, cyclophosphamide, rituximab, levothyroxine, a phosphodiesterase inhibitor, and a diuretic, she deteriorated and passed away.
Conclusion: The higher prevalence of thyroid dysfunction in juvenile SLE patients necessitates further attention. Lupus nephritis, increased creatinine level, detection of Smith (Sm) antigen, and critical condition were also at higher risk of low FT4 in juvenile SLE patients. This condition may have a worsened prognosis with prompt diagnosis and treatment.

Background: Breast cancer in Indonesia is reported to have reached 68,858 out of 396,914 new cases of cancer, with an incidence rate of 16.6% based on Globocan 2020 data. Complementary therapies are much sought after for psychological and economic reasons and have minimal side effects. Curcumin has anti-carcinogenic properties. IL-6 plays an important role in the growth and metastasis of breast cancer cells, renewal of breast cancer stem cells, and drug resistance in breast cancer stem cells.
Methods: A randomized controlled trial with post-test only group design using artificial female Balb/c strain rats (Mus Musculus) with DMBA-induced mammary adenocarcinoma nodules were reported, rats were divided into four groups randomly, namely, Control (K), Treatment 1: turmeric extract dose 100mg/KgBW (P1), Treatment 2: turmeric extract dose 150mg/KgBW (P2), Treatment 3: turmeric extract dose 200mg/KgBW (P3). Variables under study were IL-6 expression. One Way Anova test, followed by the Post-hoc Test, was used to test the difference among and between groups.
Results: The mean value of IL-6 expression in groups K (53,59 ± 8,37), P1 (50,66 ± 9,59), P2 (66,93 ± 9,64), P3 (64,58 ± 5,97). The Post-Hoc test showed significant differences in IL-6 expression from group K against P2 (p=0.038), group P1 against P2 (p=0.015), and P3 (p=0.040).
Conclusion: Turmeric extract (Curcuma longa) had an effect on IL-6 expression in the control group and the treatment group.

Published: September 2024

Introduction: Cleft Lip Palate (CLP) is a prevalent congenital anomaly in Indonesia. Gradual surgery is the gold standard treatment for the condition. However, screening for other comorbidities must be conducted before the surgery. Congenital heart Defects (CHDs) are one of the prevalent concurrent conditions of CLP patients. One of the CHD that can be found is Atrial Septal Defect (ASD). Moreover, electrolyte levels must also be assessed and treated if abnormal before surgery. Hyperkalemia is a type of electrolyte imbalance that can be found, possibly caused by increased potassium load or decreased excretion.
Case description: A 6-month-old girl was admitted to our hospital with a fever and dehydration. She complained of persistent vomiting. She had a history of CLP and CHD since birth. The echocardiogram revealed Small Secundum ASD. Laboratory results showed an elevated potassium (5.52 mEq/l). The patient was planned to get primary cleft lip repair and tip rhinoplasty. The surgery was postponed due to the patient’s condition and laboratory findings. During hospitalization, she received electrolyte imbalance correction and symptomatic treatment. A 1-week follow-up assessment showed stable condition, and the patient continued to prepare for the surgery.
Conclusion: ASD is frequently observed as one of the most prevalent comorbidities of a CLP patient. Dehydration can increase the potassium level of the blood, and it must be treated before the surgical procedure for CLP patients with ASD condition.

Background: Supraventricular tachycardia (SVT) is originating from a circuit or focus in the atrium or atrioventricular node. Atrioventricular nodal re-entrant tachycardia (AVNRT) is the predominant type. Fever may be one of the precipitating factors of SVT.
Case Description: A 22-year-old woman with the main complaint of palpitations, cold sweats and sudden shortness of breath three hours before entering the hospital. Previously, the patient had a history of fever for 6 days and a history of taking Aspirin. Physical examination showed the patient to be hypotensive, tachycardic, hyperthermic, and desaturated. Electrocardiographic examination showed SVT. The ECG rhythm became normal sinus rhythm after twice cardioversions. A complete blood count showed leukocytosis and a positive Widal test. After being observed for one day in the intensive care unit, the patient was in stable condition and no recurrent SVT occurred. Bisoprolol was given as an antiarrhythmic for maintenance.
Conclusion: The mechanism of SVT in typhoid fever is not clear, but it can be triggered by fever, cardiovascular complications or two diseases that occur simultaneously.

Pendahuluan: Supraventikular takikardia (SVT) adalah takiaritmia yang berasal dari sirkuit atau fokus pada atrium atau nodus atrioventrikular. Atrioventricular nodal re-entrant tachycardia (AVNRT) merupakan tipe yang paling dominan. Demam mungkin menjadi salah satu faktor pencetus terjadinya SVT.
Laporan kasus: Wanita usia 22 tahun dengan keluhan utama berdebar, keringat dingin dan sesak secara mendadak tiga jam sebelum masuk rumah sakit. Sebelumnya, pasien riwayat demam selama 6 hari dan riwayat minum Aspirin. Pemeriksaan fisik menunjukan pasien hipotensi, takikardi, hipertermia, dan desaturasi. Pemeriksaan elektrokardiografi menunjukan gambaran SVT. Irama EKG mejadi irama sinus normal setelah dilakukan kardioversi sebanyak dua kali. Pemeriksaan darah lengkap menunjukan leukositosis dan pemeriksaan Widal positif. Setelah diobservasi selama satu hari di ruang intensif, pasien dalam kondisi stabil dan tidak terjadi SVT berulang. Bisoprolol diberikan sebagai antiaritmia untuk pemeliharaan.
Kesimpulan: Mekanisme SVT pada demam tifoid belum jelas, namun dapat dicetuskan oleh demam, komplikasi kardiovaskuler atau dua penyakit yang terjadi secara bersamaan.

Headache is one of the most common symptoms of long coronavirus 2019 (COVID-19) syndrome. Knowledge about long COVID-19 headache is still limited, but several studies have shown evidence of several pathophysiological mechanisms involved and recommendations for primary therapy. Symptoms of long COVID-19 headache can be a worsening of previous primary headache or a new onset of headache (recurrent or daily) that occurs during acute infection or post-acute infection. Accompanying symptoms can be other COVID-19 symptoms, most commonly hyposmia. The type of long COVID-19 headache can be migraine-type headache and most commonly tension-type headache (TTH). Persistent activation of the immune system and trigeminovascular system play an important role in its pathogenesis. Until now, there are no specific therapy guidelines for long COVID-19 headache. Therefore, consideration of therapy selection is adjusted according to the current consensus according to the primary headache phenotype of long COVID-19 headache syndrome.

Nyeri kepala adalah salah satu gejala tersering dari sindrom long coronavirus 2019 (COVID-19). Pengetahuan tentang nyeri kepala long COVID-19 masih terbatas, namun beberapa studi menunjukkan bukti beberapa mekanisma patofisiologi yang terlibat dan rekomendasi terapi primer. Gejala nyeri kepala long COVID-19 dapat berupa perburukan nyeri kepala primer terdahulu atau berupa awitan nyeri kepala baru (kambuhan atau harian) yang muncul selama infeksi akut atau paska infeksi akut. Gejala penyerta dapat berupa gejala COVID-19 lainnya, tersering berupa hyposmia. Jenis nyeri kepala long COVID-19 dapat berupa nyeri kepala tipe migren dan paling banyak berupa nyeri kepala tipe tegang (tension type headache-TTH). Aktivasi persisten sistem imun dan sistem trigeminovaskular berperanan penting dalam patogenesisnya. Hingga saat ini belum ada panduan terapi spesifik nyeri kepala long COVID-19. Pertimbangan pemilihan terapi disesuaikan dengan konsensus terkini sesuai fenotip nyeri kepala primer dari sindrom nyeri kepala long COVID-19.

Technological progress demands the development of materials that have special characteristics such as high strength, stiffness, light weight, and good thermal conductivity at a low price. The development of hybrid metal matrix composites is the most important field in advanced materials science engineering.
This research determines about aluminum matrix composites (AMC) reinforced with alumina (Al2O3), Silicon carbide whisker (SiCw), and magnesium (Mg) addition. The matrix is made of 90 % pure aluminum powder, and commercially available reinforcing materials include Al2O3, SiCw, and Mg. Objectives include variation of reinforcement fraction and matrix, sintering holding temperature and time. The selection of the sample making process using powder technology followed by the sintering process at different temperatures namely 350, 450 and 550 °C with variations in holding time of 1, 2 and 3 hours. The purpose of this study was to determine the effect of variations in the fraction of reinforcement and sintering treatment on the properties of wear resistance, hardness and thermal conductivity of aluminum matrix composites.
The results showed that the composition ratio of reinforcement to aluminum in sintering treatment significantly affected the mechanical properties. The wear resistance of the material shows excellent performance, namely wear resistance of 0.000065 gr/s, hardness of 45.234 VHN and thermal conductivity of 184.855 Watt/m °C, at a reinforcement composition combination of 10 %AL2O3, 10 %SiCw and 20 %Mg and a sintering temperature of 550 °C. This indicates that the Aluminum matrix composite reinforced with Al2O3/(SiCw/Mg) is able to support the friction load due to its low wear rate, good hardness, and good thermal conductivity. This material is very suitable to be used as tribology material, brake element, especially brake drum

The problems of processing heterogeneous data are discontinuous, undifferentiated, and multimodal. The most common approaches to processing heterogeneous data are swarm intelligence algorithms (swarm algorithms). Given the above, classical gradient deterministic algorithms are inappropriate for solving the problems of processing heterogeneous data. The problem solved in the study is to increase the efficiency of processing heterogeneous data circulating in information systems, regardless of the number of data sources. The object of the study is hierarchical systems. A method for increasing the efficiency of processing heterogeneous data using a metaheuristic algorithm is proposed. The study is based on the reptile algorithm (RA) for processing heterogeneous data circulating in the system. For RA training, evolving artificial neural networks are used.
The originality of the proposed method lies in setting RA taking into account the uncertainty of the initial data, improved global and local search procedures. Also, the originality of the study lies in determining RA feeding locations, which allows prioritizing the search in a given direction. The next element in the originality of the study is the possibility of choosing an RA hunting strategy, which allows a rational use of available system computing resources. Another original element of the study is determining the initial velocity of each RA. This makes it possible to optimize the speed of exploration of each RA in a certain direction. The method provides a 15–19 % increase in data processing efficiency by using additional improved procedures. The proposed method should be used in processing large amounts of data

The main problems in the effective use of land resources as an important factor of the country's development and population's food security are considered. The study was conducted in the northern region of the Republic of Kazakhstan. The object of the study was grain-growing farms in the Akmola region.
The study concluded that satellite imagery and unmanned aerial vehicles should be used to monitor crops and assess yields in the Akmola region. These technologies allow for more efficient land management, prompt response to problems and informed decision-making. The experience of GIS application in the United States consists in the formation of database systems for all soil types that are of economic importance. There are 4 national soil databases, as well as several automated soil databases containing data on more than 13,400 soil varieties. The country's Soil Conservation Service has created soil geographic databases, including a geographic database on soil surveys, state soil associations, and major land resource areas.
The economic efficiency of land conservation measures will be determined by the amount of net income, taking into account the prevented environmental damage in value form, using the efficiency coefficient of environmental costs relative to the total production and environmental costs. The acreage area in the Akmola region on average for 2018–2023 amounted to 26,264.32 thousand hectares, the average actual crop yield was 12.5 centner/ha. Based on the given system of formulas, the estimated crop yield on non-eroded soils (Yn) is 13.5 centner/ha, and the crop shortfall (V) due to land erosion is 871.88 thousand centners of grain, which is 69,750 thousand tenge at an average grain price of 80,000 tenge/t
