Introduction: Sarcina ventriculi is a Gram (+), anaerobic, non-motile cocci, with a fermentative carbohydrate metabolism, that survives and grows without problems in environments with acidic pH. It is a known etiological agent in veterinary pathology, however its pathogenic role in humans is controversial. In recent years, the finding of this microorganism in different anatomical places has been reported in humans with increasing frequency, predominantly in the upper digestive tract, mainly in the stomach, in patients with dyspepsia and/or delayed gastric emptying, some of these cases with serious evolution, even fatal. Clinical case: we report the case of a patient with dyspeptic symptoms, whose gastric biopsy identified Sarcina ventriculi and whose targeted pharmacological treatment ended the discomfort described. To the best of our knowledge, this is the first case reported in Peru.

The study of different variables, such as pathogenesis, inflammatory profile, identification of therapeutic targets, efficacy of treatments in murine models has proven to be one of the most practical for the preclinical study of triple negative breast cancer (TNBC), the most aggressive subtype of cancer, with limited application of treatments and low survival rate. However, it must be recognized that there are other minors in which the induction of TNBC is being standardized. This review encompasses the different induction methods that have allowed the development of TNBC and the most relevant therapeutic applications by which murine models with TNBC were developed.

Authors: Fu Yanyan , Feller Daniel , Koes Bart , Chiarotto Alessandro
Published: February 2024

OBJECTIVE: To provide an updated overview of available prognostic models for people with chronic low back pain (LBP) in primary care.

DESIGN: Prognosis systematic review

LITERATURE SEARCH: We searched for relevant studies on MEDLINE, Embase, Web of Science, and CINAHL databases (up to July 13, 2022), and performed citation tracking in Web of Science.

STUDY SELECTION CRITERIA: We included observational (cohort or nested case-control) studies and randomized controlled trials that developed or validated prognostic models for adults with chronic LBP in primary care. The outcomes of interest were physical functioning, pain intensity, and health-related quality of life at any follow-up time-point.

DATA SYNTHESIS: Data were extracted using the CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies (CHARMS), and the Prediction model Risk of Bias Assessment Tool (PROBAST) tool was used to evaluate the risk of bias of the models. Due to the number of studies retrieved and the heterogeneity, we reported the results descriptively.

RESULTS: Ten studies (out of 5593 hits screened) with 34 models met our inclusion criteria, of which six are development studies and four are external validation studies. Five studies reported the area under the curve of the models (ranging from 0.48 to 0.84), whereas no study reported calibration indices. The most promising model is the Örebro Musculoskeletal Pain Screening Questionnaire Short-Form.

CONCLUSIONS: Given the high risk of bias and lack of external validation, we cannot recommend that clinicians use prognostic models for patients with chronic LBP in primary care settings. J Orthop Sports Phys Ther 2024;54(5):302-314. Epub 15 February 2024. doi:10.2519/jospt.2024.12081
Relationship Between Examination Anxiety and Academic Performance Among Secondary School Students of Delhi
Authors: Bhatt Ritika , Yadav Vishal
Published: February 2024

Academic achievement of an individual is so far considered to be influential partly by his ability to adjust to his environment, partly by his special abilities, intelligence, and aptitude which are integral parts of his personality, and partly by the intensity of drives and motives which serve as the impelling force for his activities. Academic achievement is a measure of what has been learned in the academic year. Academic achievement is determined by a student-teacher in a particular specified area of instruction. In the present study, the academic achievement of the student is determined based on the marks (total – theory and practical) obtained in the tenth-class examination. Anxiety is a normal reaction to a stressor. It may help an individual to deal with a demanding situation by prompting them to cope with it. However, when anxiety becomes overwhelming, it may fall under the classification of anxiety disorder. Generally, it helps in improving the performance of an individual. It means anxiety should not cross its threshold value; otherwise, it will reach its abnormal level (National Institute of Mental Health, 2008). This study shows the effects of gender and standard on examination anxiety of students, also the students from rural areas are facing more examination anxiety in comparison to students of urban areas.

Labelling and composition of contraband electronic cigarettes: Analysis of products from Australia
Authors: Jenkins Caitlin , Powrie Fraser , Morgan Jody , Kelso Celine
Published: February 2024

Background: The sale of nicotine-containing electronic cigarettes (e-cigarettes) is prescription only in Australia, regulated under the TGO110. Australian e-cigarette users, however, are purchasing e-cigarette products outside of the intended pathways. Methods: The labelling of e-cigarette packaging (N=388 boxes) and the chemical composition of disposable e-cigarettes and pods (N=428) were analysed for adherence to the current Australian regulations. These samples were obtained from over-the-counter retailers in NSW. Results: Following the announcement of the prescription only model for nicotine-containing e-cigarettes in Australia in mid 2021 there was a clear shift in the labelling of products. Any mention of the word ‘nicotine’ was removed from e-cigarette packaging by early 2022 and nicotine warnings were replaced with generic underage sale warnings. Despite this labelling the vast majority (98.8%) of devices analysed contained nicotine, most (89%) at high concentration (>30 mg/mL) and 4.2% contained at least one chemical prohibited by the TGO110. Conclusions: Manufacturers have removed any mention of nicotine from the original e-cigarette packaging to circumvent regulations and continue their sale. The packaging of e-cigarette products in Australia is generally not indicative of their contents, particularly nicotine, and most did not display required warnings. Ingredients with associated health risks, prohibited in legal vapes by the TGO110, were found in samples. Consequently, the risks of e-cigarette use cannot be appropriately identified from the information supplied on the packaging or device.

Authors: Mendoza Rodríguez José Leoncio , Aquino Rivera Aquiles , Lindo Gutarra César Jesus
Published: February 2024

Un conocimiento fiable sobre el rendimiento de diferentes generadores fotovoltaicos (como células individuales, módulos, arreglos, etc.) en condiciones de funcionamiento reales es esencial para la correcta selección del producto y la predicción precisa de su producción de electricidad. Se ha utilizado el método de Durisch et al. (2007) para el cálculo del rendimiento anual de módulos fotovoltaicos (PV) en lugares seleccionados, utilizando datos meteorológicos específicos del lugar. Conocer el rendimiento de los módulos fotovoltaicos es fundamental para determinar el importe requerido en la generación de electricidad para dichos módulos, lo que posibilita la selección del tipo de módulo teniendo en cuenta el nexo rendimiento-costo mayor para un determinado lugar de la instalación fotovoltaica. Las tres variables independientes de temperatura de la celda, irradiancia solar y masa de aire relativa son tomadas en cuenta en el modelo de eficiencia desarrollado que es utilizado para calcular los rendimientos de los módulos fotovoltaicos. Las características de corriente/voltaje (I/V) del módulo seleccionado son base para la obtención de los parámetros abiertos del modelo, éstas son medidas al aire libre en las instalaciones de prueba en situaciones reales de funcionamiento. Mediante el modelo, se pueden determinar las eficiencias de la celda y el módulo en todas las situaciones operativas relevantes. Se presentan los cálculos realizados de rendimiento para cinco módulos comerciales (LA361K54S de Kyocera, BP 585 F de BP Solar, UPMUS-30 de UniSolar, CIS ST40 de Siemens y WS11003 de Wuerth) para un lugar (Al Qawairah) de buena irradiación de Jordania donde se midieron datos meteorológicos confiables disponibles. Estos representan a módulos fotovoltaicos de silicio policristalino, monocristalino y amorfo, así como módulos fotovoltaicos de cobre-indio-diselenuro, CuInSe2. Se presenta los resultados del rendimiento anual de estos módulos.

Authors: Sanabria Pérez Elías Adrian , Eufracio Arias Wilder Efrain
Published: February 2024

La finalidad de esta investigación fue evaluar el comportamiento del error de estimación de un modelo matemático, en la predicción de la concentración de oxígeno disuelto (OD) durante la operación de oxigenación de agua, a diferentes profundidades de sumergencia de un difusor de burbuja fina. El modelo que se evaluó se generó al introducir las relaciones mecanicistas propuestas por Lee, en la ecuación de la teoría de la doble capa para la transferencia de oxígeno en agua. Las relaciones mecanicistas permiten calcular la concentración de saturación de OD y el coeficiente de transferencia de oxígeno en términos de las propiedades físicas del agua, además, que permite modificar la temperatura del líquido y la presión del aire. Para la evaluación, se utilizó datos de ensayos de aireación de agua desoxigenada en un recipiente a volúmenes constantes. Las profundidades de sumergencia del difusor a las cuales se experimentó fueron de 35 cm, 70 cm y 105cm. El error de estimación se calculo por diferencia de los resultados generados por simulados con el modelo y, los obtenidos experimentalmente. La simulación se desarrolló a las mismas condiciones experimentales y con el modelo en diferencias finitas. Después de la evaluación, se encontró que el error máximo fue de 0.01 ppm a 35 cm. La relación entre la profundidad de sumergencia y el error de estimación del modelo no tuvo una tendencia definida, y el efecto, es significativo.

Exploring the Impact of Phonetic Pronunciation Guides on Wine Choice and Perceived Sophistication
Authors: Marbach Cassie , Botezatu Andreea , Hall Charlie
Published: February 2024

This study delves into an often-overlooked aspect of wine consumer decision-making – the desire to appear knowledgeable in social settings. Focusing on Texas wines, which are often less well known and more intimidating to say aloud, an exploratory survey examined the impact of phonetic guides on respondents’ choice of wine off a menu. Analysis through nominal logistic regression revealed the presence of phonetic guides as the most significant predictor, suggesting consumers feel pressure to appear knowledgeable or sophisticated. Respondents who were provided menus with phonetic spellings were more inclined to choose wines with intimidating names. The inclusion of phonetic spellings not only reduced the perceived risk in ordering the wine but also served an educational role. By recognizing the influence of social factors, such as a consumer’s perceived sophistication, this study recommends establishments enhance menus with phonetic guides to empower consumers in making confident, informed choices.

Authors: Etukudo Ubong I. , Ekott Emmanuel J. , Ukpanah Esther I.
Published: February 2024

Potassium bromate (KBrO3) is a dough improver used in baking bread to increase bread size and profit. However, the additive has been banned from use due to its adverse effects on human health. Despite its ban, some bakers, especially in rural communities continue to use it. The ingestion of potassium bromate is linked to a number of clinical problems including carcinogenicity, hepatotoxicity and neurotoxicity. Bread samples from five bakeries in rural communities in Akwa Ibom State, Nigeria were randomly obtained and assessed for their levels of potassium bromate using spectrophotometric method. The absorbance of the standards and that of the samples were taken at 540 nm in the visible region of the spectrophotometer, then converted to concentrations with reference to a calibration curve constructed from pure potassium bromate sample solutions. All the bread samples contained potassium bromate and concentrations in the bread samples ranged from 5.16 – 8.50 mg/Kg. The values are beyond the allowed permissible level set by most international health standards that permit the use of the additive. The concentrations are higher than the permissible level of 0.02 mg/Kg set in Nigeria by National Agency for Food and Drug Administration and Control (NAFDAC). The ban should be enforced further especially in bakeries sited in rural communities in order to properly safeguard the health of consumers

Recently, the application of inject printing technology has gained immense among professionals and researchers in material engineering, biology, chemistry electronics, and medical fields. With the ability to print various materials,
as well as remarkable precision and speed, this technology has found significant application in the additive manufacturing process. The primary objective of this paper revolves around analyzing 3D geometry while placing a strong
emphasis on materials and structural aspects within this domain. The main goal of this paper is to eliminate conventional coating methods like lithography, focusing on adhering to established standards and maintaining the quality
of previous techniques. To achieve this aim, it is imperative to establish a seamless synergy between the chosen mechanical structure and materials. A significant hurdle in 3D printing lies in fabricating intricate geometries.
To address this issue, support structures are employed, which must be removed once the printing is finished. These supports can be printed using dissolvable materials. The process of constructing layers using separate print heads
contributes to this structural complexity. This component triggers the expulsion of ink from the nuzzle. The process of forming a district droplet is inherently contingent upon the viscosity of the ink element integrated with the
nozzle. This component triggers the expulsion of ink from the nozzle. The process of forming distinct droplets is inherently contingent upon the viscosity of the ink and its ability to adhere to specific parameters. The successful
printing of various materials relies on achieving the optimal viscosity and resistance characteristics of the ink. Additionally, this paper shows the utilization of heater and ultrasonic technologies to expand the range of printable
materials. This versatile technology is capable of accommodating a broad array of materials, encompassing nanoparticles, cells, polymers, and pigments that can be either dissolved or dispersed within a fluidic medium. Furthermore,
incorporating conductive ink into this technology opens up the potential for its application in the field of printable electronics.

Published: February 2024

The evolution of the theory of technological sovereignty is considered. It has been established that some of the first works devoted to this topic were published by M. Merkhov, who identified three basic conditions affecting the technological dependence of states. It was revealed that in the mid-70s of the last century, a theory of dependence was formed, including two directions: the structuralist school and the Marxist movement. Representatives of this theory called the restraining influence of highly developed states as a source of technological dependence. In addition, modern EU program documents aimed at ensuring technological sovereignty are reviewed.

Does political dynasty affect local spending in Indonesia?  Only a few articles have taken up the political economy issues in Indonesia This study provides empirical analysis that focuses on explaining the effect of the political competition through dynasty winning in the mayoral election to the local spending that focuses on functional-classified expenditure at the district level. Using the Regression Discontinuity Design (RDD) estimation, this study examines whether the dynasty mayor has different trends in the way to spend local expenditure compared to the non-dynasty mayors. Due to the limited political competition, this study finds the magnitude effect of the dynasty mayor on local spending that used to drive the regional economy. Compared to the non-dynasty mayors on a separate sub-dataset, this study finds different effects of a dynasty between the incumbent and the non-incumbent dynasty mayor on local spending. The incumbent dynasty mayor negatively affects ‘visible’ expenditure’ e.g., grant and social assistance expenditure, social protection expenditure, housing and public amenities expenditure, education expenditure, dan current expenditure. This study also finds negative effects of the political dynasty on local spending from the dynasty mayor elected during the period of simultaneous mayoral election (2015-2018).

Objective: To investigate the relationship between transfusion frequency, serum ferritin levels, and hepatomegaly in beta-thalassemia major patients. Study Design: Cross-sectional study. Setting: Thalassemia Center, Liaquat University Hospital, Hyderabad. Period: January 2023 to June 2023. Material & Methods: Among 158 patients, age until 19 years, and β-thalassemia type major was considered as inclusion criteria. Data regarding hematological parameters and hepatomegaly was collected after informed consent. Data was analyzed using SPSS (version 22). Chi-square test was used to investigate the association between ferritin levels and hepatomegaly while Pearson’s correlation was used assess the correlation between ferritin levels and transfusion frequency. P-Value ≤ 0.05 was considered as statistically significant. Results: Majority of the participants were males (58.22%) as compared to females (41.77%). The mean age of the study participants was 9.31±4.47 years, and the mean age at first transfusion was 8.98±0.93 years. Majority of the participants were underweight 107(67.72%). Monthly transfusion rate was 1.95±0.31.The mean serum ferritin levels among the study participants were 2033.06±1309.36 ng/mL. Hepatomegaly was found to be present in 99 (62.65%) of the study participants. Statistically significant positive correlation between the frequency of transfusion and serum ferritin levels (r = 0.71, p<0.05) was observed. The difference of hepatomegaly in low-ferritin vs high-ferritin was also found to be statistically significant (p<0.05). Conclusion: It was concluded that higher transfusion rates were associated with elevated ferritin levels, and there was a significant association between higher serum ferritin levels and the presence of hepatomegaly.

Objective: To determine the influence of serum ferritin levels on glycemic control in patients with type 2 diabetes mellitus (T2DM) patients. Study Design: Cross-sectional study. Setting: Department of Medicine, Liaquat University Hospital, Hyderabad, Pakistan. Period: July 2021 to December 2021. Material & Methods: A total of 180 patients of 30-60 years of age and either gender, and known cases of diabetes mellitus for ≥3 year duration were included. Demographic, clinical and laboratory data was recorded. HbA1c below 7% was labeled as good glycemic control while HbA1c above or equal to 7% was designated as poor glycemic control. The serum ferritin ≥307 μg/L was considered as raised. Association of glycemic control with respect to serum ferritin levels was noted. Results: In a total of 180 patients of T2DM, the mean age, duration of diabetes, and HbA1c were 53.62 ± 5.82 years, 11.91±4.92 years, and 12.41 ± 5.73% respectively. The mean serum ferritin was 512±22.53 ug/L, whereas serum ferritin was raised in 109 (60.5%). The serum ferritin levels were significantly higher in patients with poor glycemic control than those having good glycemic control (56.0% versus 44.0%, p=0.044). Conclusion: In contrast to individuals with good glycemic control, patients with poor glycemic control more frequently had elevated serum ferritin levels, according to the current study. In order to properly manage diabetes patients and prevent the negative effects of elevated serum ferritin levels, serum ferritin should be included in the usual screening protocol of diabetic patients while monitoring their glycemic status.
