Вивчення проблеми раку щитоподіної залози (РЩЗ) і розробка ефективних методів його діагностики й лікування є одним із пріоритетних напрямів сучасної ендокринної хірургії, ендокринології, онкології та патологічної анатомії. Проаналізувати структуру злоякісних пухлин щитоподібної  залози, сучасні аспекти їх морфологічної діагностики та можливості застосування нанотехнологій. Для досягнення мети на базі ПАВ КНП «Обласна клінічна лікарня Івано-Франківської обласної ради» опрацьовано 804 направлення на гістологічне дослідження щитовидної залози (ЩЗ) хворих на різні захворювання ЩЗ в період з 2018 по 2022 рр. Проведений аналіз вітчизняних та закордонних наукових праць щодо сучасних методів діагностики РЩЗ. Результати проведеного дослідження вказують на те, що злоякісними новоутвореннями щитоподібної залози частіше хворіють жінки у віковому діапазоні від 40 до 65 років, середній вік 52,89 років. Серед новоутворень найбільша частка припадає на папілярну карциному, яка спостерігається 82,7% на фоні хронічного тиреоїдиту. Важливим у ранній діагностиці та визначені гістологічного варіанту РЩЗ є дослідження молекулярних біомаркерів за допомогою молекулярних методів, таких як полімеразна ланцюгова реакція (ПЛР), секвенування геному, мас-спектрометрія і інші. Найважливішими молекулярними маркерами РЩЗ є визначення мутаціїї генів RET, BRAF і RAS. Застосування нанотехнологій у діагностиці РЩЗ може покращити можливості виявлення цього захворювання на ранніх стадіях та забезпечити більш точне та ефективне лікування. Однак важливо зазначити, що багато з цих технологій все ще перебувають у стадії досліджень, і їх клінічне впровадження може зайняти час. Використання нанотехнологій у біопсії може сприяти підвищенню точності та ефективності цього процесу, а також зменшити ризики ускладнень для пацієнтів. Однак, перед впровадженням таких технологій в клінічну практику, потрібні додаткові дослідження та клінічні випробовування для оцінки безпеки і ефективності.

Number sense is a skill that contributes significantly to learning mathematics. However, number sense is often positioned as a fundamental skill whose development is more focused on children. The contribution of number sense in mathematics is even more apparent at higher levels of education. Ironically, number sense seems ignored and has become a rarely studied topic in higher education. Thus, the student’s number sense ability profile seems buried with various problems. This study aims to reveal the profile of prospective elementary school teachers’ number sense abilities and the factors causing their failure in solving math problems during the implementation of blended learning. This study uses a qualitative approach with 37 prospective elementary school teachers as research subjects. The observation of the test and lecture activities is the data collection method. The results showed that the prospective elementary school teachers’ number sense ability was still relatively low. Based on the components, the order of number sense abilities is from the highest, namely: (1) knowledge and number facilities with the achievement of 14.41%; (2) knowledge and facilities for number operations with the achievement of 8.12%; and (3) knowledge and facilities of numbers and operations for computing settings with an achievement of 1.8%. The low number sense ability is caused by the habit of solving problems procedurally and the failure to solve problems due to misconceptions, not understanding concepts, inaccuracy, inability to understand questions, and difficulty representing fractions. Various factors causing the failure arose due to the limitations of implementing blended learning.

Diabetes Mellitus (DM) is a degenerative disease that modifies the body’s glucose metabolism. Although glucose is a vital energy source for body cells, individuals with diabetes can either not use insulin efficiently or do not create enough of this hormone, which controls blood sugar. This review aimed to explore the multi-target treatment for diabetes. This study investigates explicitly recent reports published in peer-reviewed journals indexed in various databases, including Web of Science, Scopus, PubMed, Google Scholar, and Science Direct. Individuals with diabetes are more likely to experience other health issues, such as elevated blood pressure and cholesterol. Environmental factors that can influence the onset of diabetes include air pollution, temperature and weather, and stress. With the shortage of diabetes specialists and healthcare experts coupled with an inefficient healthcare service in low- and middle-income nations, there is a need to introduce more creative approaches to treat diabetes. Although literature reveals that no one-size-fits-all method is available for managing diabetes because each person's reaction to the disease varies depending on several factors, such as the diabetes stage and the person’s susceptibility to complications, this study posits that there could be a headway in diabetes management by exploring multi-targets treatment. Introducing lifestyle change, diet modification and physical activity could reduce the risk of death due to diabetes. This study also highlights how diabetes can be managed in the rural and urban settings. Adopting telemedicine and web-based initiatives could impact diabetes treatment positively.

Published: July 2024

Background

Machine learning (ML) risk prediction models, although much more accurate than traditional statistical methods, are inconvenient to use in clinical practice due to their nontransparency and requirement of a large number of input variables.

Objective

We aimed to develop a precise, explainable, and flexible ML model to predict the risk of in-hospital mortality in patients with ST-segment elevation myocardial infarction (STEMI).

Methods

This study recruited 18,744 patients enrolled in the 2013 China Acute Myocardial Infarction (CAMI) registry and 12,018 patients from the China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE)-Retrospective Acute Myocardial Infarction Study. The Extreme Gradient Boosting (XGBoost) model was derived from 9616 patients in the CAMI registry (2014, 89 variables) with 5-fold cross-validation and validated on both the 9125 patients in the CAMI registry (89 variables) and the independent China PEACE cohort (10 variables). The Shapley Additive Explanations (SHAP) approach was employed to interpret the complex relationships embedded in the proposed model.

Results

In the XGBoost model for predicting all-cause in-hospital mortality, the variables with the top 8 most important scores were age, left ventricular ejection fraction, Killip class, heart rate, creatinine, blood glucose, white blood cell count, and use of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs). The area under the curve (AUC) on the CAMI validation set was 0.896 (95% CI 0.884-0.909), significantly higher than the previous models. The AUC for the Global Registry of Acute Coronary Events (GRACE) model was 0.809 (95% CI 0.790-0.828), and for the TIMI model, it was 0.782 (95% CI 0.763-0.800). Despite the China PEACE validation set only having 10 available variables, the AUC reached 0.840 (0.829-0.852), showing a substantial improvement to the GRACE (0.762, 95% CI 0.748-0.776) and TIMI (0.789, 95% CI 0.776-0.803) scores. Several novel and nonlinear relationships were discovered between patients’ characteristics and in-hospital mortality, including a U-shape pattern of high-density lipoprotein cholesterol (HDL-C).

Conclusions

The proposed ML risk prediction model was highly accurate in predicting in-hospital mortality. Its flexible and explainable characteristics make the model convenient to use in clinical practice and could help guide patient management.

A Case Study of Diagnosis & Treatments How is Functional Abdominal Pain Diagnosed?
Authors: Babu Dr. Chilakalapudi Meher
Published: July 2024

Abstract: Vacuum levels are commonly measured in terms of in. Hg (inches of mercury), mm Hg (Torr), and microns. We monitor motor cortical excitability, brain stimulation-induced neuroplasticity. The most common causes of abdominal pain and diarrhea are infections, such as gastroenteritis (stomach flu), and food allergies, lactose intolerance, and stress. Common bowel disorders, such as IBS and Crohn's disease, can also cause these symptoms. Viral gastroenteritis is an infection of your intestines that typically causes watery diarrhea, pain or cramping in your abdomen, nausea or vomiting, and sometimes fever. People commonly call viral gastroenteritis “stomach flu,” but the term is not medically correct. Flu viruses do not cause viral gastroenteritis. The most common symptom of chronic pancreatitis is long-standing pain in the middle of your abdomen. If you have chronic pancreatitis, you might get repeated episodes of acute pancreatitis, where your pain gets worse. Your pain may get worse with eating, drinking and drinking alcohol. You may also develop jaundice.

Published: July 2024

Abstract: The term ‘hydrocarbon’ is self-explanatory which means compounds of carbon and hydrogen only. Hydrocarbons play a key role in our daily life. You must be familiar with the terms ‘LPG’ and ‘CNG’ used as fuels. LPG is the abbreviated form of liquified petroleum gas whereas CNG stands for compressed natural gas. Another term ‘LNG’ (liquified natural gas) is also in news these days. This is also a fuel and is obtained by liquifaction of natural gas. Petrol, diesel and kerosene oil are obtained by the fractional distillation of petroleum found under the earth’s crust. Coal gas is obtained by the destructive distillation of coal. Natural gas is found in upper strata during drilling of oil wells. The gas after compression is known as compressed natural gas. LPG is used as a domestic fuel with the least pollution. Kerosene oil is also used as a domestic fuel but it causes some pollution. Automobiles need fuels like petrol, diesel and CNG. Petrol and CNG operated automobiles cause less pollution. All these fuels contain mixture of hydrocarbons, which are sources of energy. Hydrocarbons are also used for the manufacture of polymers like polythene, polypropene, polystyrene etc. Higher hydrocarbons are used as solvents for paints. They are also used as the starting materials for manufacture of many dyes and drugs. Thus, you can well understand the importance of hydrocarbons in your daily life. In this unit, you will learn more about hydrocarbons

Ex nihilo nihil fit – Cidades novas como infraestruturas territoriais no Brasil e em Portugal
Authors: Trevisan Ricardo , Oliveira Maria Manuel Lobo Pinto de
Published: July 2024

Cidades de raiz – não espontâneas – têm em seu passado pré-fundacional elementos decisivos que induziram a sua gênese. A razão de existir e onde se materializar passam necessariamente por decisões de agentes, instituições e conjunturas político-econômico-sociais específicas que direcionam cada um desses empreendimentos. Em alguns casos, as cidades novas implicaram a destruição dos ecossistemas (humanos e naturais) locais e do seu eventual desaparecimento, num quadro em que a espécie humana os encarava apenas como subsidiários (quase sempre supérfluos) para a realização dos seus propósitos colonizadores. Este artigo, decorrente de pesquisa de pós-doutoramento, tem como propósito qualificar cidades novas, aquelas intencionalmente criadas e profissionalmente projetadas, como dispositivos infraestruturais de ativação e urbanização territorial. Mais que produtos-fim de uma dinâmica político-espacial, podem essas cidades ser compreendidas como engrenagens intermediárias a atividades produtivistas e extrativistas? Na busca por resposta, direciona-se a atenção às cidades fundadas no centro-sul amazônico (Brasil) e na região de Sines (Portugal) nos anos 1970, surgidas como resultado do desenvolvimentismo, do autoritarismo estatal, das dinâmicas de capitalização e acumulação e da participação ampliada de setores privados. Guardadas as devidas proporções e diferenças escalares, os processos de ocupação, colonização, infraestruturação e exploração de bens naturais perfazem ambos os territórios, incluindo práticas urbanizadoras predatórias aos ecossistemas locais. Assim, tais cidades tornam-se nosso campo exploratório nesta investigação, conduzida por um olhar histórico, respaldado por consultas a fontes primárias e secundárias e por visitas in loco. Ao entender que “nada nasce do nada”, este estudo qualifica cada cidade nova como representação das condicionantes que levaram a seu nascimento e a seu posicionamento estratégico no sistema capitalista recente.

How the Women of the SOE Were Made to Wage War: A Brief Account of Noor Inayat Khan’s Experience as a Biracial Female SOE Agent
Authors: Veerasammy Leah B.
Published: July 2024

During the Second World War, thousands of individuals served with the Special Operations Executive (SOE), a secret organization within the British army; and many of them were women. SOE agents carried out clandestine tasks of espionage and sabotage throughout Nazi occupied Europe. The war created various opportunities for women to join the war effort and the SOE was one of the few that allowed women to use the realities of their sex to succeed in their work. Although femineity often aided female agents in their work, it was simultaneously an extra disadvantage they learned to navigate. Particularly unique in her work with the SOE was British Indian agent Noor Inayat Khan. In addition to the difficulties Inayat experienced as a result of her gender, she carried the hardships of her race. Fascinatingly, in the same way female agents triumphed their femineity, Inayat Khan was aided by her experience as a woman of color. This article explores the ways in which Inayat Khan wielded both her femineity and racial identity as strengths, despite the disadvantages they often presented, as an SOE agent.

¿COMPRAR O REPARAR?: REFLEXIONES ACERCA DE LOS MECANISMOS JURÍDICOS PARA COMBATIR LA OBSOLESCENCIA PROGRAMADA
Authors: Tapia Fraile María José
Published: July 2024

El paradigma del desarrollo económico ha puesto énfasis en la manufactura de bienes de consumo, alcanzando niveles de producción sin precedentes. Con el propósito de mantener dicho ritmo de crecimiento, los conglomerados empresariales requieren que las ventas de sus productos se mantengan constantes en el tiempo. Esto está íntimamente vinculado con la vida útil de los artefactos, pues si ésta se prolonga, proporcionalmente decrecerá la demanda, y en dicho contexto surge la noción de obsolescencia programada. Luego de conceptualizar el fenómeno y otorgar clasificaciones de este, se abordarán las consecuencias de dicha práctica empresarial, a la luz de la protección al medioambiente. Asimismo, se analizará la regulación de la obsolescencia planificada en el derecho foráneo y se otorgarán propuestas de solución relacionadas con la economía circular, consumo sostenible y reparabilidad de los artefactos.

Published: July 2024

La dirección de proyectos es un proceso que ayuda a proporcionar mayor confianza en el logro de los objetivos, ya que se minimiza el desperdicio de recursos, se reducen los riesgos y se facilita la gestión del cambio. En este artículo, se presentan los hallazgos de un estudio sobre la implementación de prácticas de dirección de proyectos en pequeñas y medianas empresas (pymes) en México para identificar cuáles son los marcos de referencia o metodologías más implementados. El estudio se llevó a cabo para una muestra aleatoria de 113 pymes de México, en las cuales se han empleado proyectos con una duración promedio de un año. Los resultados demuestran que el 52 % de estas no tiene proyectos documentados ni bien definidos, con bajos niveles de monitoreo y control; además, dichas implementaciones son identificadas de forma reactiva y ejecutadas a través de procesos y procedimientos desarrollados de forma interna, mediante marcos de referencia propios que no están probados, pues se considera que los estándares como los del PMI, Prince2 o Ágil son muy complejos o costosos. Lo anterior trae como consecuencia que, con base en los resultados obtenidos, solo el 50 % de dichas organizaciones tengan proyectos exitosos, y aproximadamente el 41% de estos se encuentran bien definidos o definidos; además, en promedio, el 70 % ejecuta al menos tres proyectos en paralelo, lo que requiere de marcos de referencia estandarizados y probados para asegurar el éxito de estos a lo largo de su implementación en la organización.

Non-destructive Evaluation of Oil Content and Carotene in Oil Palm Fresh Fruit Bunches Based on Optical Properties Using Partial Least Square (PLS)
Authors: Rahmi Suaidah , Cherie Dinah , Ifmalinda Ifmalinda , Makky Muhammad
Published: July 2024

Crude palm oil (CPO) is a raw material for making cooking oil that comes from palm oil, which is greatly influenced by the quality of oil palm fresh fruit bunches (FFB). Oil and carotene content in the FFB influence the quality of palm oil. The oil content is usually determined using a chemical method (Soxhlet extraction) which is time consuming and destructive. This research aimed to predict the oil and carotene content contained in oil palm FFB using partial least square (PLS). In this research, the sample used was the Tenera variety with a maturity of 140-160 day after anthesis (DAA) and 200-220 DAA. The nondestructive method involves recording images using an optical camera, which produces RGB and L*a*b* values. Results showed that PLS predicts the relationship between optical properties and oil and carotene content in palm oil.

Authors: Fendha Arya
Published: July 2024

Budaya patriarki di Indonesia mengalami anomali, ditandai dengan peningkatan jumlah perempuan yang bekerja. Dampak dari semakin banyaknya perempuan menjadi penopang utama ekonomi keluarga adalah munculannya “bapak rumah tangga”, yaitu seorang bapak yang banyak meluangkan waktu atau bertanggung jawab sepenuhnya terhadap urusan domestik dan pengasuhan dalam keluarga. Bapak rumah tangga biasanya memiliki penghasilan lebih kecil dari pada istri atau bahkan tidak memiliki penghasilan sama sekali. Penelitian ini bertujuan untuk melihat bagaimana hubungan konsep diri terhadap sikap suami istri di dalam rumah tangganya dimana suami berperan sebagai bapak rumah tangga. Situasi suami yang bukan sebagai pencari nafkah utama atau bahkan tidak sebagai pencari nafkah akan mempengaruhi bagaimana suami dan istri memahami konsep dirinya. Konsep diri dalam keluarga yang demikian penting untuk dipelajari karena posisi suami yang tidak menjadi pencari nafkah utama berpotensi menimbulkan konsep diri negatif yang berakibat pula pada sikap yang negatif. Penelitian ini melibatkan 23 suami dan 24 istri dari Daerah Istimewa Yogyakarta dan Ponorogo. Dari penelitian ini didapatkan bahwa terdapat hubungan positif yang signifikan antara konsep diri dan sikap suami yaitu sebesar 0,498. Sedangkan konsep diri istri berhubungan positif signifikan terhadap sikap mereka sebesar 0,458.

Introduction: Sudan faces the impact of SARS-CoV-2, emphasizing the urgency of timely detection and effective management. This study, conducted in Kassala, Sudan, aimed to evaluate key hematological, biochemical, and inflammatory markers in confirmed and suspected COVID-19 patients.
Methodology: A cross-sectional hospital investigation was carried out in Kassala State, eastern Sudan, spanning from September 2020 to January 2021. Clinical and sociodemographic data were collected from individuals suspected of having COVID-19 using a structured questionnaire. Nasopharyngeal swab was targeted for the detection of SARS-CoV-2 while a blood sample was processed for haematological and biochemical parameters.
Results: The study included 371 participants, revealing a prevalence of COVID-19 PCR positive of 61.7% (229/371). In particular, most were male (65%), with a mean age of 42.9±19.9 years. A substantial case fatality rate of 15.7% (36/229) was observed, predominantly among people 60 years and older (P < 0.001). RT-PCR-confirmed patients exhibited significant associations with elevated erythrocyte sedimentation rate, C-reactive protein levels, prolonged Prothrombin time, extended partial thrombin time, leucocytosis, neutrophilia, lymphopenia and hypocalcemia (P < 0.000).
Conclusion: This study illuminates the impact of COVID-19 on crucial hematological, renal electrolyte, inflammatory, and coagulation markers. These findings have the potential to enhance patient outcomes and reduce mortality rates by guiding informed actions and shaping public health policies.

Abstrak         Pada komponen medis harus memiliki bentuk presisi, produk presisi pada dunia medis harus memiliki ketahan korosi dan kuat, salah satu jenis material yang digunakan dalam pembuatan komponen medis adalah titanium. Titanium dan paduannya merupakan jenis material yang digunakan dalam implan tulang dikarenakan memiliki sifat biocompatible dan resistensi korosi yang baik. Penelitian ini bertujuan untuk mencari pengaruh dari polishing terhadap kepresisian dan kehalusan permukaan ulir kortikal. Polishing merupakan jenis metode pemolesan yang dipilih dalam penelitian ini dan material yang digunakan adalah Ti-6Al-4V ELI. Parameter pemolesan yang digunakan adalah putaran spindel 1000, 1200, dan 1400 rpm, waktu sebesar 90, 100, dan 110 menit, dan serbuk yaitu porang, pasir silika,  dan abu gosok. Kepresisian geometri ulir dapat dilihat melalui pengukuran kesalahan sudut α dan kesalahan sudut β menggunakan profile projector dan kehalusan permukaan ulir dapat dilihat melalui scanning electron microscope. Pada penelitian ini menunjukan bahwa  polishing berpengaruh pada parameter putaran spindel terhadap kesalahan sudut β dan serbuk berpengaruh terhadap kesalahan sudut α. Hasil scanning electron microscope menampilkan bahwa polishing dapat meningkatkan kehalusan permukaan ulir serta pengurangan dimensi pada baut ulir. Penggunaan serbuk dengan kesalahan terkecil dalam penelitian ini adalah abu gosok, abu gosok terbukti memiliki pengaruh kecil terhadap pemolesan. Selain itu abu gosok lebih ekonomis dibandingkan dengan porang dan pasir silika.
