Belief matematis yang dipahami sebagai keyakinan terhadap mata pelajaran matematika, kenyataannya sangat berpengaruh dalam proses pembelajaran matematika, khususnya terhadap hasil belajar peserta didik. Tujuan penelitian ini adalah menganalisis belief matematis guru pemula dalam mengajar dan belajar matematika, ditinjau dari media Digibook yang telah dikembangkan. Sebanyak 9 guru pemula dengan belief matematis pada aspek belajar matematika yang berbeda menjadi subjek dalam penelitian ini. Penelitian ini termasuk pada deskriptif kualitatif dengan pengambilan data berupa media Digibook yang dikembangkan oleh subjek, angket belief matematis yang sebelumnya telah divalidasi dan wawancara semi terstruktur. Hasil penelitian ini menunjukkan bahwa guru pemula dengan keyakinan belajar level platonis meyakini bahwa dalam belajar matematika, pemahaman akan konsep merupakan inti dari belajar. Hal ini berdampak pada cara mereka mengajar, meyakinkan siswa bahwa matematika bukan hanya prosedur. Bagi guru pemula dengan keyakinan belajar problem solving, belajar merupakan proses mengeksplorasi pengetahuan dan media pembelajaran berperan sebagai alat bantu, alat komunikasi dan alat pengembangan berfikir matematis. Hasil penelitian ini mengimplikasi bahwa guru pemula dengan semangat belajar dan mengajarnya serta keinginan dalam mengembangkan media pembelajaran mampu menghasilkan media Digibook yang sesuai dengan karakteristik dan kebutuhan siswanya.Mathematical beliefs, which are understood as beliefs about mathematics subjects, are in fact very influential in the process of learning mathematics, especially on student learning outcomes. The purpose of this study is to analyze the mathematical beliefs of novice teachers in teaching and learning mathematics, in terms of the Digibook media that has been developed. A total of 9 (nine) novice teachers with mathematical beliefs in different aspects of learning mathematics became subjects in this study. This research is included in descriptive qualitative with data collection in the form of Digibook media developed by the subject, a mathematical belief questionnaire that has been previously validated and semi-structured interviews. The results of this study show that novice teachers with platonic level learning beliefs believe that in learning mathematics, understanding concepts is the core of learning. This has an impact on the way they teach, convincing students that math is not just a procedure. For novice teachers with problem solving learning beliefs, learning is a process of exploring knowledge and learning media acts as a tool, a communication tool and a mathematical thinking development tool. The results of this study imply that novice teachers with their passion for learning and teaching and the desire to develop learning media are able to produce Digibook media in accordance with the characteristics and needs of their students.

One obstacle that occurs in the learning of junior high school students in solving complex and abstract problems is characterized by a misunderstanding of concepts (misconceptions). One effort to find out the misconception is to use the Four Tier Diagnostic Test (FTD Test). While the material used in this study is a comparison material that is synonymous with the concept of a comparison. This study aims to determine the type of misconception and causes of misconceptions experienced by students on comparison material using FTD Test. This type of research is descriptive research with a qualitative approach. The subjects in this study were 5 Class VIII-D students of SMPN 1 Tarogong Kaler as many as 5 people were chosen using the Purposive Sampling method. The instruments used in this study were FTD Test sheets, interview guidelines, and observation sheets. Data were analyzed using data reduction techniques, data presentation, and data verification1/drawing conclusions. The results of this study students experience classification misconceptions, correlational misconceptions, and theoretical misconceptions. The cause of misconceptions in students is from their own students who do not understand the comparison material, the teacher's habit of giving routine practice questions, and is also influenced by learning online.

Published: September 2023

Background: EEG recording showed a definite relationship between epileptiform EEG discharges and cognitive impairments (transient cognitive impairment “TCI”), since interictal spikes, which correspond to a large intracellular depolarization with evoked action potentials, in many ways mimic a “miniseizure.” Interictal spikes can result in transitory cognitive impairment with the type of deficit dependent on where in the cortex the spike arises. The interictal spikes, particularly if frequent and widespread, can impair cognitive abilities, through interference with waking learning and memory, and memory consolidation during sleep.Objectives: the aim of this study is to evaluate the effect of subclinical epileptic discharges on cognitive function in patients with epilepsy.Patients & Methods: This is a prospective study conducted in Basra teaching hospital in the period from December 2009 to February 2011 in order to evaluate the effect of epileptic discharge on cognitive function. EEG exam and cognitive function test (P300) was done for each patient four times at three months interval period, and one time for control group. Two hundred twenty four (224) patients included in this study with age range from (12-40) years. the EEG obtained after 30 mints of recording was categorized in to three groups frequent, infrequent and normal EEG record.Results: we found that patients with frequent IEDs have high mean P300 latency when compared to patients with infrequent and normal EEG exam, also the mean p300 latency significantly reduced (more improvement in cognitive function) after treatment with AEDs.Conclusion: Treatment of patients with frequent epileptic discharge improve cognitive function in patients with epilepsy, and reduction of IEDs greatly improve cognitive abilities in epileptics.

Published: September 2023

Background: The role of Human papillomaviruses (HPV) in the etiology of ovarian cancer remains unclear and the results are controversial. Several studies have verified the presence of HPV DNA in both malignant and benign ovarian tumors.Objectives: Determine the percentage of detection of HPV high (16&18) and low risk types (6&11) in surface epithelial ovarian carcinoma compared to benign and control groups.Materials And Methods: Molecular detection and genotyping of HPV DNA were performed in 76 ovarian tissue blocks by using in situ hybridization (ISH) technique for detecting and localization of high risk HPV (16 and 18) and low risk HPV (6&11) types.Results: The presence of ISH signals for HPV DNA in benign group (71%) was higher than that found in malignant group (64%). HPV 16 was the most predominant type followed by HPV18, 6, and 11 respectively in both malignant and benign groups. High risk HPV were presented with low score and high intensity in both malignant and benign tumors. Low risk HPV types were detected in high score and intensity in benign tumors which significantly differed from that with malignant tumors, which revealed low score and low intensity. The percentage of co-infection of low risk HPV6&11 in benign group was higher (16.9%) than malignant group (7.1%). Only significant difference was found in combination of both high and low risk HPV types.Conclusions: This finding reflects a possible role of HPV virus in the carcinogenesis of ovarian tumors. HPV infection may play a relative role in the pathogenesis of ovarian carcinomas or it could facilitate its progression.
Efectos de la modificación de textura en la dieta sobre la saciedad temprana, la percepción de la capacidad saciante y la ingesta energética en pacientes con Enfermedad renal crónica en terapia sustitutiva de un Hospital General de Puebla, México.
Authors: Morales Koelliker Diana 
Published: September 2023

Introducción: la Enfermedad Renal Crónica (ERC) se caracteriza por una función renal disminuida (50-70%), provocando alteraciones en la eliminación de sustancias del catabolismo proteico como la creatinina y la urea, y alteraciones en el metabolismo de macronutrimentos y micronutrimentos por lo que la terapia sustitutiva de la función renal (diálisis peritoneal, hemodiálisis o trasplante renal) es necesaria. Derivado del estado catabólico por el incremento en el gasto energético diario, los pacientes con ERC se encuentran en un estado nutricional deficiente. Las hormonas reguladoras del apetito, principalmente la leptina y la grelina, generan un efecto inhibidor del apetito limitando así el consumo calórico diario. Esta condición metabólica en conjunción al permanente catabolismo sitúa a los pacientes en una situación vulnerable a la aparición de complicaciones y el consecuente deterioro de la calidad de vida. Una dieta modificada en textura puede ayudar a los pacientes a incrementar el consumo energético y proteínico para, eventualmente, mejorar su estado nutricional. Objetivo: determinar el efecto de la textura de la dieta sobre la saciedad temprana, consumo energético y percepción de la capacidad saciante en pacientes con ERC en terapia sustitutiva. Método: Estudio analítico, longitudinal, prospectivo y cuasiexperimental. Se incluyeron a pacientes voluntarios con ERC en diálisis peritoneal continua ambulatoria. En el estudio participaron 14 sujetos pacientes de ambos sexos con una medida de 44±15.8 años. Resultados: se observó que el consumo energético, de carbohidratos, lípidos y proteínas durante el desayuno se incrementó cuando se ofreció la dieta modificada en textura (puré) (p<0.05), los pacientes reportaron menor percepción de la capacidad saciante y menor saciedad postprandial en este tipo de dieta. Conclusión: La dieta modificada en textura es una alternativa asequible que permite el consumo energético y nutrimental óptimo para el paciente con ERC evitando las barreras de la falta de apetito y saciedad temprana.

BackgroundStatin therapy in multimorbid older individuals with polypharmacy is controversial, particularly in primary prevention of cardiovascular disease. Thereby, physicians must weigh potential benefits against potential side effects, drug-drug interactions, and limited life expectancy.AimTo assess the prevalence and determinants of potentially inappropriate statin therapy in multimorbid older patients.MethodsWe conducted a cross-sectional analysis of patients aged ≥70 years with multimorbidity and polypharmacy in the Swiss study center of OPERAM, a cluster-randomized trial on pharmacotherapy optimization to reduce drug-related hospital admissions. We assessed potential underuse (no statin but formal indication) and potential overuse (statin but no formal indication, including predicted &gt;60% one-year mortality based on the Walter Score) based on current guidelines for patients in secondary and primary cardiovascular prevention. We assessed the association of potential statin overuse and underuse with six patient characteristics (age, gender, number of diagnoses, number of medications, mental impairment, being housebound) in LASSO-selection analyses.ResultsOf 715 multimorbid older adults (79.7 ± 6.5 years, 39.9% women), 337 (47%) were on statin. Statin therapy was appropriate in 474 (66.3%), underused in 130 (18.2%), and overused in 111 (15.5%) patients. In participants in secondary cardiovascular prevention (n = 437), being female (odds ratio [OR] 2.65, 95% confidence interval [CI] 1.67–4.22) was significantly associated with potential underuse while being housebound (OR 3.53, 95%CI 1.32–9.46) and taking ≥10 medications (OR 1.95,95%CI 1.05–3.67) were associated with potential overuse. In participants in primary cardiovascular prevention (n = 278), 28.1% were potentially under- (9%) or overusing (19%) a statin, with no identified risk factor.ConclusionA third of hospitalized multimorbid older patients with polypharmacy potentially (either) overused or underused statin therapy. Among patients in secondary cardiovascular prevention, women were at risk for potential statin underuse. Housebound patients and those taking ≥10 medications were at risk for potential overuse of a statin. Physicians should carefully evaluate the indication for statin prescription in multimorbid older patients with polypharmacy.

Published: September 2023

BackgroundFat-soluble vitamins, including vitamins A, D and E, play an important role in the regulation of glucose and lipid metabolism, and may affect infant birth weight. Evidence on the association of birthweight with fat-soluble vitamins is controversial. Therefore, this study aims is to determine the associations of birthweight with vitamin A, D, and E concentrations in cord blood.MethodsA total of 199 mother–infant pairs were enrolled in the study. According to gestational age and birth weight, the mother–infant pairs were divided into small for gestational age (SGA), appropriate for gestational age (AGA), and large for gestational age (LGA). The Vitamin A, D, and E concentrations in serum were measured by high-performance liquid chromatography tandem-mass spectrometry.ResultsThe concentrations of vitamin A in the SGA group were significantly lower than those in the AGA and LGA groups. The concentrations of vitamin E in the SGA group were significantly higher than those in the AGA and LGA groups. However, no significant differences were observed in vitamin D among the three groups. Being male (β = 0.317, p &lt; 0.001) and birth weight (β = 0.229, p = 0.014) were positively correlated with the levels of vitamin A. Birth weight (β = -0.213, p= 0.026) was correlated with lower levels of vitamin E. No correlation was found between influencing Factors and the levels of vitamin D (p&gt; 0.05). After adjusting for gestational age, sex, mother’s age, delivery mode, pre-pregnancy BMI, and weight gain during pregnancy, the levels of cord blood vitamin A were positively correlated with birth weight (p=0.012).ConclusionThe infant’s birth weight is associated with the levels of cord blood vitamins A and E. The dysregulation of vitamins A and E in infants may be a risk factor for fetal growth and future metabolic diseases.
