Published: September 2023

Rainfall is very influential in daily life, including in agriculture. According to the Jember Regency Government, the majority of the economic activities of the Jember people come from the agricultural sector. Significant changes in rainfall conditions will adversely affect the agricultural sphere. The Water Resources Office of Jember Regency measures rainfall directly. Precipitation measurement can also be made indirectly using the Global Satellite Mapping of Precipitation (GSMaP), a project promoted by the Japan Aerospace Exploration Agency (JAXA) to produce rainfall accumulation globally. Rainfall predictions are urgently needed to address rainfall-related issues. The Adaptive Neuro-Fuzzy Inference System (ANFIS) method is an effective method for prediction because its working principle combines adaptive methods of artificial neural networks and fuzzy logic. The RMSE in the ANFIS training and testing process on daily rainfall was 12.7464 and 14.6268. Furthermore, RMSE in ANFIS training and testing on monthly rainfall was 7.6336 and 8.1456. The predicted daily rainfall in Jember Regency on January 1, 2023, is 3.1971 mm. Meanwhile, the predicted monthly rainfall in Jember Regency in January 2023 is 19.9114 mm.
Penundukan Diri Non-Muslim dalam Qanun Jinayat Aceh: Penyimpangan atau Pengembangan Asas Hukum Pidana?
Authors: Din Mohd. , Abubakar Ali , Halim Marah 
Published: September 2023

This article aims to provide legal logic for the permissibility of choosing criminal law for non-Muslims who commit criminal acts regulated in the Aceh Qanun Jinayat based on one of the legal principles raised (endorsement) as the basis for establishing norms in the qanun in question, namely the principle of submission which is actually not recognized in criminal law. The research data are several decisions of the Syar’iyah Court in Aceh against violations of the Qanun Jinayat committed by non-Muslims. It is assumed that the decisionis a shift in the principles of criminal law. This problem will be analyzed by observing the basic principles of criminal law, including the principles of the application of criminal law and the politics of criminal law. The results of the study showed that from the point of view of the principles of criminal law which is a compelling law, this submission is a deviation, but from a legal-political perspective, because the birth of permissible provisions in qanuns is a political process, where the demand to apply Islamic Sharia which basically only applies to Muslims, then as a softening of the territorial principle non-Muslims are allowed to vote.

Authors: Qothrunnada Glenis Grytha , Agusmawanti Prima , Sari Rina Kartika 
Published: September 2023

Background: Dental erosion is a non-carious lesion that occurs due to demineralization caused by exposure to acidic materials. The tooth remineralization process can be restored by adding calcium-containing materials to the teeth. There are other sources of calcium that come from animals but are still not and are rarely explored, one of which is duck egg shells. Duck egg shells contain around 94 – 97% CaCO3 and the content of duck egg shells reaches 90% calcium levels.
Method: The experimental research design was in the form of a post test only control group design with a total sample of 12 permanent premolars. Duck egg shell nanohydroxyapatite is given in a gel preparation. Tooth microporosity was measured using a Scanning Electron Microscopy with a micro magnification of 5000x
Result: The hypothesis test was carried out by using the one way ANOVA test and significant results were obtained (P≤ 0.05) for all treatment groups. The LSD test was carried out to see the differences between groups and the results obtained between the group of 20% duck egg shell extract gel, 5% sodium fluoride and the untreated group obtained a p value = 0.000 (p

Published: September 2023

Background: Orthodontic treatment is a treatment that aims to correct malrelation and malformations to restore masticatory function, esthetics and obtain a good arrangement of teeth to achieve proper occlusion. The bracket is a component in orthodontic treatment that functions as a force conductor. The use of a bracket with a type of stainless steel material has several advantages such as an economical price, corrosion resistance, and high strength, but the habit of consuming carbonated drinks in stainless steel bracket users can cause the release of Ni ions, which can trigger hypersensitivity reactions in some person. Information is needed regarding the relationship between the release of Ni ions on a stainless steel bracket soaked in carbonated drinks to type IV hypersensitivity reactions, especially to an increase in the number of neutrophil cells.
Method: The design of this study used a post-test group design using a sample of 10 male Wistar rats which were divided into 2 groups (n = 5), namely the treatment group and the control group. Calculation of the number of neutrophils using histopathological observations with Hematoxylin-Eosin staining using an electric microscope with 400x magnification.
Result: The average number of neutrophils in the treatment group was 4.14 and the control group was 1.04. Statistical tests using the Welch T-Test showed significant differences between the two groups (P

Authors: Kozachyshyn Nataliia I. , Netiazhenko Vasyl Z. , Salo Sergii V. 
Published: September 2023

The aim. To analyze changes in the activity of the platelet link of hemocoagulation in patients with chronic coronary syndrome before and after percutaneous coronary intervention (PCI) against the background of prior antiplatelet therapy.
Materials and methods. We examined 67 patients (mean age 65.2±8.6 years) who were undergoing inpatient treatment at the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine. Patients with different regimens of antiplatelet therapy were compared before and after PCI. At the time of hospitalization, patients were receiving both monotherapy and dual antiplatelet therapy (those with a history of myocardial infarction up to 12 months) in standard doses. The control group consisted of 25 people of similar age (62.7±6.5 years). The activity of platelet hemostasis was evaluated by the turbidimetric method and the light transmission fluctuation method. Statistical processing was carried out using the MedStat v.5.2 and Statistica 8.0 software.
Results. Before PCI, dual antiplatelet therapy using aspirin and ticagrelor suppressed the activity of platelet hemostasis, compared to dual antiplatelet therapy with acetylsalicylic acid and clopidogrel. Patients receiving monotherapy did not achieve the desired effect. After PCI, the group of patients who took the combination of aspirin and ticagrelor responded better to the therapy than those who received aspirin and clopidogrel.
Conclusions. The use of dual antiplatelet therapy with acetylsalicylic acid and ticagrelor reduced both spontaneous and induced aggregation.

Background. According to statistics, about 26 million people worldwide suffer from heart failure (HF). Currently, sodium-glucose cotransporter 2 inhibitors are widely prescribed for treatment of HF with reduced left ventricular ejec-tion fraction (LVEF) throughout the world. Therefore, prescribing drugs that have anti-hypoglycemic effect in patients without diabetes mellitus still raises some concerns, considering the possible risk of developing hypoglycemia.
The aim. To assess the effect of dapagliflozin on glycemic variability in treatment of HF with reduced LVEF in patients without diabetes mellitus.
Materials and methods. The study was conducted at the premises of the Department of Cardiometabolic Diseases of the Ukrainian Children’s Cardiac Center. Twenty-three patients with HF with reduced LVEF of various etiologies without diabetes mellitus were evaluated. The variability of glycemia in the study group was assessed using continuous glucose monitoring. For this, the MiniMed iPro2 continuous glucose monitoring system (Medtronic, USA) was used.
The sensor was inserted on day 1 and removed on day 7. Average value of glycemia during the day, time in range (TIR) and time below range (TBR) were calculated on the basis of data about the level of glucose in the intercellular fluid obtained for 6 days of monitoring. Dapagliflozin 10 mg once a day was prescribed to all the patients included in the study for the treatment of HF with reduced LVEF. The average follow-up period was 7 months.
Results. The examined patients were divided according to clinical and laboratory characteristics. Assessment of daily variability of glycemia during 6 days of observation using continuous glucose monitoring in patients on dapagliflozin revealed average blood glucose level from 4.4 mmol/L (minimum value) to 6.0 mmol/L (maximum value). These results indicate minimal risk of hypoglycemia and safety of using dapagliflozin in case of HF with reduced LVEF without concomi-tant type 2 diabetes mellitus. TIR and TBR indicators were also evaluated in patients with and without prediabetes. The obtained data allows to assert the same safety of taking dapagliflozin in both these groups, due to the fact that time of glycemia <3.9 mmol/l does not exceed the indicator of 5%.
Conclusion. The use of dapagliflozin as part of complex therapy of HF with reduced LVEF does not elevate the risk of developing hypoglycemia in patients without diabetes mellitus.

Authors: Popov Volodymyr V. , Bolshak Oleksandr O. , Boukarim Valery Zh. , Khoroshkovata Olena V. , Trembovetska Olena M. 
Published: September 2023

Introduction. Coronavirus disease (COVID-19)-associated pneumonia was a dangerous disease at the beginning of 2021. However, there are almost no records of early infectious endocarditis of prosthetic heart valve in the presence of such a disease. We present an interesting clinical case of successful treatment of complicated pathology.
The COVID-19 outbreak involved unique clinical complications that were superimposed on the progressive heart failure due to prosthetic mitral valve dysfunction (its detachment) which did not allow time for active antiinflammatory therapy. Urgent replacement of the prosthesis made it possible to eliminate the infection and paved the way for successful long-term antibacterial, antifungal and antiviral therapy.
The aim. To determine the features of management of patients with complex clinical pathology: prosthetic valve endocarditis associated with COVID-19 and severe lung inflammation in the early postoperative period.
Case report. This work presents rare clinical case. A 46-year old male patient underwent successful surgery (mitral valve replacement with posterior leaflet preservation and left atrium resection) at the Department of Surgical Treatment of Acquired Heart Diseases of the National Amosov Institute of Cardiovascular Surgery and was discharged in satisfactory condition. One month later, he was hospitalized again and diagnosed with an early infectious endocarditis of prosthetic mitral valve and bilateral polysegmental COVID-19-associated pneumonia. After a week of medicinal preparation (antibacterial therapy), the patient underwent repeat mitral valve replacement in the presence of progressive heart insufficiency due to increasing paravalvular insufficiency. Postoperative period elapsed without significant complications. The patient was discharged in satisfactory condition on day 15 after surgery and primary rehabilitation.
Conclusion. Having a specific etiology, pneumonia significantly damaged mitral prosthesis structures by increasing paravalvular insufficiency. Consequently, the patient underwent life-saving repeat mitral valve replacement in the presence of COVID-19-associated pneumonia and under massive antibacterial treatment which continued for 60 days after the patient’s discharge. An important element of successful treatment of COVID-19-associated pneumonia is the selection of adequate antibacterial, antifungal and antiviral drugs.

Published: September 2023

The aim. To study and substantiate the new principles of organization in the provision of cardiac surgical care under martial law.
Materials and methods. The article presents an analytical review using reference databases of scientific medical publications and analysis of our own database of cardiac surgical care for the period from 2014 to July 2023. The group of patients consisted of 501 male subjects. The age of the study participants varied from 21 to 58 years (mean age 41.5 ± 2.2 years). The analysis of monitoring results included the most common diseases of the circulatory system, combat injuries of the heart and main vessels.
Results. The article pays attention to the current challenges that have arisen before organization of the system of providing cardiac surgical care under martial law. It is emphasized that the area of cardiac surgical assistance to military personnel is being developed at the National Amosov Institute of Cardiovascular Surgery of the NAMS of Ukraine since 2014, when the Anti-Terrorist Operation / Joint Forces Operation began. In cooperation with military doctors, new methods of treatment of patients with gunshot and mine-explosive wounds are being developed and implemented. It was established that among patients with cardiovascular pathology, combat injuries of the heart and main vessels make up 7.9%, which coincides with the frequency of combat injuries of the chest given in literary sources. Moreover, the length of hospital stay of patients with combat injuries of the heart and main vessels does not exceed the number of bed days during surgical treatment of the most common diseases of the circulatory system. It was also established that some of the injured patients had concomitant pathologies that required, in addition to cardiac surgical care, medical care of other specialists: a surgeon, a neurosurgeon, an orthopedic traumatologist, an otolaryngologist, a psychologist, etc.
Conclusions. It has been established that organization of the system of providing cardiac surgical care under martial law is primarily designed to ensure: optimization of resources by strengthening the personnel reserve; cooperation with specialists of other specialties, medical institutions of various subordinates and international partners; changing patient routes taking into account, first of all, their safety; expanding narrow specialization of medical institutions by creating multidisciplinary teams.
Features of the Course of Atrial Fibrillation in Patients with the History of COVID-19: Impact on the Possibility and Tactics of Restoring Sinus Rhythm
Authors: Stasyshena Oksana V. , Sychov Oleg S. 
Published: September 2023

Introduction. Atrial fibrillation (AF) is a potentially life-threatening complication of infection. In general, AF has a high prevalence in elderly population with cardiovascular risk factors and comorbidities. Thus, the presence of AF correlates with adverse outcomes in patients with previous coronavirus disease (COVID-19) which deserves increased attention and should be appropriately treated to prevent adverse outcomes.
The aim. To analyze the prevalence and clinical course of AF in hospitalized patients after COVID-19 to determine approaches to restoring sinus rhythm.
Materials and methods. The study included 179 patients with various types of heart rhythm and conduction disorders who suffered from COVID-19 and were hospitalized to the Department of Clinical Arrhythmology and Electrophysiology of the National Scientific Center “The M.D. Strazhesko Institute of Cardiology, Clinical and Regenerative Medicine of the NAMS of Ukraine” from 09/20/2020 to 12/21/2021. 116 patients were hospitalized with AF who suffered from coronavirus infection between 1 and 12 months ago (5.1 ± 0.2 months on average). Other heart rhythm and conduction disorders were the cause of hospitalization for 63 patients (35.2%). The first group was formed by 36 people (31%) in whom AF occurred after coronavirus infection. The second group included 25 patients in whom the form of AF changed, namely: there was a transition from paroxysmal form of AF to persistent AF, or persistent AF to a permanent form of AF. The third group included 55 patients in whom the form of AF did not change. However, in the third group, two subgroups were formed: 3A consisting of 35 patients, in whom, although the form of AF did not change, the frequency or duration of paroxysms increased, and 3B, which included 20 patients without significant changes in the course of AF. As a control group, 49 patients with AF without a history of coronavirus infection were examined.
Results. In most patients (65%), the reason for hospitalization was AF. The first recorded paroxysms of this arrhythmia were recorded in 31% of patients 2 months after the coronavirus infection. In this group, more than half of the cases (58.4%) were patients with persistent AF, and 8.3% of those hospitalized failed to restore sinus rhythm. In those who had AF before COVID-19, 75% of its course worsened: the frequency or duration of paroxysms increased. The persistent form of AF was dominant and occurred after a previous infection in 58% of cases. In patients who had AF before COVID-19, its course worsened (in 76% of the examined persons) after the infection. Patients with a history of coronavirus infection had more frequent use of drug therapy, which is probably due to the delayed time of hospitalization to the clinic from the onset of the paroxysm.
Conclusion. AF is the most common arrhythmia and has a worse course in hospitalized patients after coronavirus infection.
A Case of Duodenal Bleeding in a One-Year-Old Child in the Early Postoperative Period after the Surgical Correction of Congenital Heart Defect
Authors: Tsymbal Olena I. , Boyko Serhii M. 
Published: September 2023

Background. Gastrointestinal bleeding in children is a rather rare pathology. This especially applies to the bleeding in the postoperative period after surgical interventions that are not related to the pathology of the gastrointestinal tract. As a result, clinicians are not alert to the occurrence of such complications, which, in turn, can lead to late diagnosis and delay in the treatment of bleeding.
Case report. We present a clinical case of duodenal bleeding in a one-year-old child in the early postoperative period after radical repair of ventricular septal defect by patching the defect. Laboratory parameters on admission: hemoglobin 120 g/L, red blood cells 4.37×1012/L. On the first postoperative day, hemoglobin was 103 g/L, hematocrit was 33%. On the 5th day after the operation, the boy had a currant jelly stool. Hemostatic therapy was provided: transfusion of fresh frozen plasma at a dose of 10 mL/kg, single administration of tranexamic acid at a dose of 10 mg/kg. The bleeding was stopped. After hemostatic therapy, hemoglobin was 105 g/L, hematocrit was 31%. Within 24 hours, fibrogastroduode-noscopy was performed which revealed an ulcer of the duodenal bulb covered with fibrin. The boy was consulted by gastroenterologist. Pathogenetic therapy was prescribed: proton pump inhibitors, antacids, enveloping drugs. The child was discharged home in a satisfactory condition on the 15th day after the operation under the supervision of a district pediatrician, cardiologist, and gastroenterologist. Laboratory parameters at discharge: hemoglobin 91 g/L, red blood cells 3.3×1012/L.
Conclusion. The problem of gastrointestinal complications, including gastrointestinal bleeding in young children af-ter cardiac surgery, is extremely insufficiently covered in the scientific literature. Many questions remain unsolved re-garding the prevention, early diagnosis and treatment of bleeding, so research in this field remains relevant for both clinicians and scientists.
