Impacts of water quality on water availability of reservoirs in the state of Ceará
Authors: Silva Antonio Jose Pereira da , Cavalcante Larissa Diniz , Mamede George
Published: June 2024

ABSTRACT This study aims to analyze the impacts of water quality on the water availability of reservoirs using the total phosphorus (TP) concentration as an indicator. Three reservoirs in the State of Ceará were investigated for this purpose: Acarape do Meio (29.6 hm3); Aracoiaba (162 hm3); and Pentecoste (395.6 hm3). For estimating the TP load yielded in the studied catchments, equations that correlate census data on animal, agricultural and human production with TP gross production were applied. The TP balance in the three reservoirs was carried out based on the Chapra equation for complete mixing, considering periods with different hydrological regimes: wetter period (2004 to 2010); and period with prolonged drought (2011 to 2020), indicating a decay relationship of TP concentrations for larger stored volumes. This study proposed the introduction of the PIR (Phosphorus Input Ratio) concept, which refers to the ratio between the TP input load into the reservoir and the gross TP load yielded in the catchment. Considering that the hydrological regime can influence the TP transport conditions, a correlation between PIRs and runoff coefficients was established, presenting a good adjustment. The effects of including water quality restrictions regarding TP content on water availability at the reservoirs were also addressed. TP concentrations at the reservoirs can negatively impact water availability subject to quality constraints. Therefore, the adoption of techniques to reduce the production and export of TP from the study areas is extremely important for making water available within the quality standards required.

This study was conducted to determine some biological properties of the potato tuber moth Phthorimaea operculella, a new host of the egg-larval parasitoid Chelonus oculator at different temperatures. The emergence rate, development time, longevity, adult weight, and sex ratio of C. oculator were assessed at three different temperature levels (20±1 ºC, 25±1 ºC, 30±1 ºC), 65±5% humidity and 16:8 light: dark conditions. Forty potato tuber moth eggs, aged 0-24 hours, adhered to the filter papers, were placed into the tubes, and presented to the parasitoids for parasitization for a day. At the end of this period, the parasitized eggs were allowed to develop at the specified temperatures. The study found the highest emergence rate was found at 30 °C, with 20.5%. The longest development period occurred at 20 °C, determined as 49.00±2.00 days in females and 52.27±1.64 days in males. The longest longevity of the parasitoid was found to be 41.71±2.29 and 45.73±3.75 days in males and females, respectively. The highest adult weight was observed at 25 °C for both males and females. The sex ratio was found to be in favor of males as the temperature decreased. It is thought that these results can be used for the biological control of potato tuber moth in the field and storage conditions for release studies.

Carbonate reservoir of Kais Formation in Salawati Basin, West Papua, is the most famous oil and gas reservoir in the eastern part of Indonesian Archipelago since 1970’s. Nowadays, new prospects in this area are more challenging and most relevant near the infrastructure of previous oil and gas fields. In this study, a relatively new seismic dataset was investigated to figure out new prospects in carbonate reservoir rocks in the area of interest. In this preliminary study, where seismic data are not supported by well data, direct hydrocarbon indicator (DHI), seismic attribute, and spectral decomposition (CWT: continuous wavelet transform) allow the authors to characterize the reservoir geometry and to predict pore fluids within the reservoir rocks. The reservoir geometry of carbonate reef of Kais Formation (C1) was identified by seismic reflectors with high amplitude contrast at the top C1. The hydrocarbon indicator was predicted by DHI where dim spots, flat spots, and polarity reversals are indicative of hydrocarbon prospects. From the attribute analysis, the attribute instantaneous amplitude detected the top carbonate C1, whereas pore fluids were predicted from high sweetness attribute. In addition, spectral decomposition CWT method confirms the top C1, identified as saturated rock by the frequency of 10 Hz, 20 Hz, and 30 Hz. Based on a seismic study in the researched area, the target zone is expected to be a very promising hydrocarbon reservoir, specifically a carbonate reservoir. As a result, the preferred well-test location is in a region with access to the Kais Formation limestone reef layer. This study can assist in reservoir characterization, especially in areas with limited well control.

Authors: Vázquez-Rodríguez Oscar
Published: June 2024

There is a growing interest in the acquisition, promotion, and assessment of the competencies necessary for research among university students. However, within the field of educational evaluation, one confronts the complexity of establishing precise measures that inform about the performance of this competence. This study examined the measurement instruments employed to assess the research competence of university students in the educational field. The research followed the PRISMA protocol for conducting systematic literature reviews and performed a critical analysis of the identified measurement instruments. The aspects under investigation included: proposed use, target population, construct’s conceptualization, instrument format, and validity evidence’s generation. Findings indicated that these instruments are employed both to assess the acquisition and mastery of research competence and to evaluate the effectiveness of pedagogical interventions aimed at fostering it. A lack of representativeness of the student population in disciplines with an educational focus was identified. The components and indicators of research competence share a common organization into dimensions spanning from metacognitive skills to contextual conditions within which research is practiced. There was an observed tendency towards the use of questionnaires and a prevalence of traditional approaches in validation procedures.

Published: June 2024

Установлены зависимости между двоичными цифровыми кодами преобразователя и формами симметричного семифазного напряжения. Использован матричный подход описания трех алгоритмов управления. Столбцы матриц представлены как двоичные коды преобразователя, соответствующие базовым векторам; строки матриц соответствуют дискретным формам фазных напряжений. Установлено, что при изменении временной последовательности чередования фаз и неизменной форме фазного напряжения активными становятся первая, третья или пятая гармоники дискретной формы фазного напряжения. При вариации алгоритмов пространственно-векторной модуляции возможна частотная, амплитудная и фазовая модуляция результирующего напряжения. Эти процессы соответствуют изменению чередования строк матриц и изменению цифровых кодов столбцов (кодов базовых векторов). Результаты работы могут быть использованы при создании общей теории многофазных двигателей, а также имеют практическое значение для разработчиков электропривода.

A pesquisa objetiva apresentar a sistematização dos indicadores regionais do Alto Piranhas, comparando os índices dos municípios pertencentes a Região Metropolitana de Sousa-PB, a partir da análise sobre a transição para o novo marco legal. Metodologicamente, o estudo trata-se de uma pesquisa documental, realizada através da busca nos bancos de dados do Sistema Nacional de Informações sobre Saneamento (SNIS), na Fundação Getúlio Vargas (FGV-DATASAN), no Instituto Brasileiro de Geografia e Estatística (IBGE), no Fórum Nacional de Entidades Metropolitanas (FNEM), no Painel Saneamento Brasil do Instituto Trata Brasil, tendo em vista, a busca pelos indicadores quantitativos acerca do abastecimento de água e esgotamento sanitário dos municípios pertencentes a Região Metropolitana de Sousa-PB. Os resultados demonstraram que a CAGEPA é órgão público responsável pelo saneamento básico nas cidades de Aparecida, Nazarezinho, Santa Cruz, São Francisco, São José da Lagoa Tapada, Marizópolis, Lastro e Vieirópolis, desempenhando o papel de planejar, executar e operar serviços de saneamento básico, compreendendo desde a captação, adução, tratamento e distribuição de água e coleta, até o tratamento e disposição final dos esgotos. No caso do DAESA, percebe-se a existência de problemas organizacionais e estruturais, no tocante à disponibilização de dados a respeito do saneamento básico realizado na cidade de Sousa, dificultando a análise mais aprofundada acerca do perfil de abastecimento realizado no munícipio. Diante do exposto, conclui-se que ao se ter acesso aos indicadores dos serviços de saneamento básico na Região Metropolitana de Sousa, pode-se traçar metas mais objetivas para otimizar os serviços de saneamento na região.

Published: June 2024

O herbicida glifosato está entre os mais utilizados no mundo. Assim, tornou-se crescente a preocupação com seus possíveis efeitos adversos sobre a saúde. Este estudo teve como objetivo avaliar os efeitos reprodutivos do consumo crônico de ração contaminada com o herbicida glifosato em ratos. Ratos receberam ração nebulizada com solução de glifosato em diferentes concentrações: 0 (grupo controle - GC), 20,69 (grupo de baixa concentração - GBC), 34,63 (grupo de média concentração - GMC) ou 51,66 ppm por dia (grupo de alta concentração GAC), durante 180 dias. A qualidade dos espermatozoides foi prejudicada pelo glifosato. A porcentagem de espermatozoides com movimentação progressiva e não progressiva e contagem de espermatozoides no testículo foram reduzidos nos dois grupos de maior concentração de exposição (GMC e GAC). Houve aumento de alterações de cabeça com curvatura em forma de alfinete e anormal e cauda isolada e enrolada nos três grupos expostos com redução significativa no número de espermatozoides normais. A integridade de membrana plasmática do espermatozoide não foi afetada pelo herbicida.  A exposição crônica oral ao herbicida glifosato em diferentes concentrações causou alterações na morfologia de espermatozoides de ratos adultos. Tais achados são cruciais, pois sugerem que a exposição prolongada ao glifosato pode ter implicações prejudiciais na fertilidade masculina, ressaltando a necessidade de constantes revisões nas práticas de uso do herbicida e na avaliação dos seus riscos à saúde.

Published: June 2024

O setor industrial busca constantemente métodos que impulsionem a produção, reduzam custos e sejam ecologicamente viáveis para seus subprodutos e resíduos A vinhaça, um subproduto da indústria sucroalcooleira produzido em volumes impressionantes - entre 13 e 18 litros para cada litro de etanol fabricado - é comumente empregada na fertirrigação. No entanto, o descarte excessivo desse resíduo no solo pode resultar em danos significativos ao longo do tempo. Nesse contexto, várias pesquisas estão em andamento para identificar técnicas viáveis de tratamento desse efluente. A fotocatálise heterogênea, um processo oxidativo avançado, tem se mostrado eficiente em muitos casos, embora o uso de subprodutos como fotocatalisadores ainda seja pouco explorado na literatura. Este estudo investiga a fotocatálise heterogênea como uma técnica eficiente para tratar tanto a vinhaça quanto efluentes sintéticos contendo corante azul de metileno. Ao utilizar diferentes concentrações de pó de rocha basáltica como fotocatalisador, os experimentos demonstraram uma redução de até 98,3% na concentração de corante e reduções na demanda química de oxigênio (DQO) e demanda bioquímica de oxigênio (DBO) da vinhaça, até 4,4% e 70,8%, respectivamente. Apesar da DQO não apresentar variação expressiva, a redução significativa na DBO indica uma eficácia considerável do tratamento. Esses resultados não apenas oferecem uma alternativa para a gestão da vinhaça e aproveitamento de subprodutos como o pó de rocha, mas também contribuem para o avanço do conhecimento sobre o tratamento de efluentes industriais, promovendo uma indústria mais sustentável e consciente do meio ambiente.

Published: June 2024

Objetivo: Investigar o efeito do período da pandemia de Covid-19 na prática de suavização intencional de resultados sobre o valor de mercado (VM) das empresas listadas na [B]3.
Metodologia: A amostra compreendeu dados das empresas não financeiras do Novo Mercado, no período de 2017 a 2021. Para o cálculo das variáveis de suavização intencional, foram utilizados os modelos propostos por Lang et al. (2012). As estimações foram realizadas com o uso de painel dinâmico, com Estimador de Momentos Generalizados.
Resultados: O período da pandemia de Covid-19 teve um efeito negativo no VM das empresas. No entanto, nesse período, a suavização intencional geral apresentou redução do seu impacto negativo, enquanto a suavização intencional por accruals teve o seu efeito negativo intensificado. Os resultados sugerem que a redução do nível de operações das empresas no período pandêmico afetou mais intensamente o efeito da prática de suavização geral e menos intensamente a suavização intencional de resultados sobre o valor das empresas.
Contribuições: A pesquisa contribuiu com a literatura sobre a suavização de resultados em países emergentes nos períodos de incerteza e serve como alerta para os efeitos de tais práticas sobre os preços dos ativos na bolsa brasileira.

Published: June 2024

Introduction. Young people are highly susceptible to manifesting the various dimensions of anxiety, which have been associated with certain personality traits. Objective. To determine the association between personality traits (PT) and the dimensions of clinical anxiety (CA), trait anxiety (TA), and state anxiety (SA) in young students in the areas of health sciences in the state of Jalisco, Mexico. Method. Five hundred and twenty-one students (with an average age of 20.5 years) enrolled in psychology, nursing, and nutrition degree programs participated, 75.2% of whom were women. From Abril 2020 to May 2021, a cross-sectional design was used to virtually evaluate CA (Beck’s inventory), TA and SA (the Spielberger inventory), and PT (Eysenck’s inventory). Linear regression analysis was used to calculate correlations (R) and determination coefficients (R2) to predict the dimensions of anxiety in relation to PT. Results. 25.7% and 24.8% of participants scored for severe and moderate CA respectively, while 54.3% obtained high scores for TA and SA. For CA, the neuroticism PT yielded an R of .607 and an R2 of .367; for TA, an R of .803 and an R2 of .644; and for SA, an R of .735 and an R2 of .540. Discussion and conclusion. The high correlation between the neuroticism PT and anxiety in young people was probably exacerbated by the restrictive conditions of the COVID-19 pandemic. In young students, the neuroticism PT is a predictor for the development of various dimensions of anxiety.

Published: July 2024

Despite the complexity of and threats to American Jewish identity, little is known regarding how it is strengthened in adulthood. The purpose of this quantitative descriptive study was to understand the types of activities and minority experiences that strengthen Jewish identity and how this may differ from those with higher religious and cultural identification. Participants included 546 Jewish adults from 39 states who completed a survey covering topics related to Jewish activities, minority experiences, belongingness, continuity, Jewish identity, and demographics. Results indicated that regardless of cultural or religious identification, there were many similarly endorsed activities and minority experiences, even negative ones, that strengthen Jewish identity among adults. Implications for multicultural counseling competency when working with American Jews and ethno-religious identity are discussed.
On the ‘Double Protection’ Issues
Authors: Zubkov S. B.
Published: July 2024

Based on regulatory sources, materials from the judicial and disciplinary practice of regional bar chambers, and bar instruments, the paper analyzes certain aspects of double protection, when a court appointed attorney participates in the case along with an arranged lawyer. In particular, the paper studies issues on the priority of legally protected values when deciding on the admissibility of ‘double protection’; on the degree of completeness and consistency of legal regulation of relevant legal relations in their legal and professional ethical context; on the validity of expanding the legal grounds for the participation of a court-appointed attorney; on the effect of the rule of Part 3 of Art. 50 of the Code of Criminal Procedure of the Russian Federation on the failure of a defense lawyer to appear within 5 days in relation to a court-appointed lawyer; on the possibility of challenging the courtappointed attorney due to their «low qualifications.» Given the incompleteness and inconsistency of regulation of this sphere, which is significant both legally and professionally and ethically, and taking into account the different tasks in the implementation of the functions of criminal proceedings by the bodies of inquiry and investigation, as well as the state prosecution — on the one hand, and the defense — on the other, it is important to find there is a certain regulatory balance in this area. It should also be taken into account that the institution of «double protection» in one way or another touches on the issue of conflict of public and private interests. According to the author, it is necessary to eliminate the incompleteness and inconsistency of the normative regulation of the institution of «double protection», develop unified approaches to the implementation of this institution by lawyers, ensure consistent corporate disciplinary practice in matters of bringing a lawyer to disciplinary liability, promote the unity of law enforcement practice in this matter by the bodies of inquiry and investigation and courts.

Pancreaticoduodenal and distal resections are crucial components of pancreatic cancer treatment. Pancreatic fistula is one of the most common complications of these surgeries. The main criterion for the diagnosis of pancreatic fistula is the increase of amylase drain level more than 3 times from the normal blood level. Pancreatic fistulas worsen the long-term results of cancer treatment and increase the risk of bleeding per an erosion of visceral vessels, pancreatitis and peritonitis, as well as increase the duration of hospital stay. Risk factors for pancreatic fistula can be split in two categories: patient-related and procedure-related. The patient-related risk factors are: male sex, age more than 70 years, small or large diameter of the pancreatic duct, epithelial type of the malignancy, comorbidities and a high volume of drainage fluid in the postoperative period. Surgical risk factors are: the severity of intraoperative blood loss, “soft” pancreas, duration of surgery and surgical techniques.
The most effective method for fistula prophylaxis is intraoperative risk evaluation with initial pancreatectomy in case of high risk. At the same time, it is possible to use medical glues and pharmacological methods for prevention and treatment of postoperative pancreatic fistulas, but further investigations are required. Thus, prevention and treatment of postoperative pancreatic fistulas is a crucial component of management of patients who undergo surgery for pancreatic malignancies.

La menta piperita es una planta medicinal, su cultivo es considerado un interesante rubro de renta, sin embargo, es susceptible al déficit hídrico, siendo ésta la causa principal de los bajos rendimientos de este cultivo en parcelas sin sistema de riego. Con el objetivo de evaluar parámetros productivos y económicos del cultivo de menta piperita con coberturas orgánicas e inorgánicas de suelo que ayuden reducir el déficit hídrico, se llevó a cabo esta investigación en un diseño completamente al azar, compuesto por cinco tratamientos (suelo sin cobertura, mulching negro, mulching blanco, cascarilla de arroz y pasto pacholí) y cuatro repeticiones, totalizando 20 unidades experimentales. Las variables evaluadas fueron: longitud de brotes basales, cantidad de brotes basales y brotes laterales, rendimiento de masa fresca y seca. Adicionalmente, se analizó la rentabilidad de cada tipo de cobertura. Todas las medias fueron sometidas al análisis de varianza (ANAVA) y comparadas por el Test de Tukey al 5%. En cuanto a la longitud de brotes basales, los mejores resultados fueron con la utilización de mulching negro, seguido por el mulching blanco y pasto pacholí; la mayor cantidad de brotes laterales con 16,45 con el mulching blanco, en cambio en la cantidad de brotes basales fue el testigo que presentó una mayor cantidad con 4,15. El mulching blanco presentó mayor rendimiento que el testigo para la masa fresca y masa seca con 1.544 kg ha-1 y 628 kg ha-1, respectivamente. Al analizar la rentabilidad en la masa fresca de la menta piperita, la utilización del mulching blanco fue más factible, mientras que en masa seca se observó una rentabilidad negativa para todos los tratamientos.

Published: July 2024

Powdery mildew disease (Erysiphe necator Schwein) is a significant threat to grape cultivation in vineyards. Severe yield and quality losses could occur in vineyards when this pathogen is not managed correctly. Several commercial grape varieties are highly susceptible to powdery mildew. Therefore, large quantities of fungicides are applied throughout the growing season. In addition to yields and quality, new grapevine varieties that are genetically resistant to powdery mildew are required for sustainable viticulture. This study was conducted through molecular screening of powdery mildew resistance genes in nine different Vitis labrusca L. genotypes (TEG-Vl-1, TEG-Vl-2, TEG-Vl-3, TEG-Vl-4, TEG-Vl-5, TEG-Vl-6, TEG-Vl-7, TEG-Vl-8, and TEG-Vl-9) grown in the Black Sea Region of Türkiye. After PCR amplifications using Ren1, Ren3 and Ren9 locus-specific primers, Ren1, and Ren 9 genes were detected in three genotypes (TEG-Vl-1, TEG-Vl-3, and TEG-Vl-4). However, the Ren3 gene was not detected in any genotypes. It was concluded based on present findings that Vitis labrusca L. genotypes with resistance genes could be used as genetic resources in grapevine breeding programs and significant economic benefits can be provided accordingly.

Published: June 2024

The integration of sports science and camera sensing technology has recently emerged to be an advanced analytical tool in sportsperson performance enhancement. The use of computing power and a web-based application can provide quick information analysis and data reporting between coaches and athletes. The design of an archery analytic workflow is demonstrated in this paper using the Python Flask framework, video analytic algorithms, a structured video inventory framework, MongoDB database setup and integration of the Keypoint R-CNN machine learning backend. A user-friendly data visualisation interface on the front end is integrated in the software to deliver athletes’ analytical capabilities such as thorough frame-by-frame video analysis, posture consistency estimation and joint kinematic analysis. This web application framework is not limited to archery sports, and can be extended to numerous sports, such as shooting, weightlifting and cycling. The significance of integrating camera sensing technology with the sports science field can offer quantitative and qualitative observations to improve training programs and performance evaluation.
Adverse Drug Reactions in Multi-Drug Resistant Tuberculosis Patients, in India, who had received DOTS Plus Treatment along with Home Care and Counselling
Authors: Vaghela Joyce
Published: July 2024

Background: Adverse drug reactions are common in MDR-TB patients on treatment. An adverse drug reaction (ADR) is defined as an appreciably harmful or unpleasant reaction resulting from an intervention related to the use of a medicinal product. Revised National Tuberculosis Control Programme used 24-months long Category IV/DOTS Plus regimen for treatment of MDR-TB. The Community Health Department of St. Stephen’s Hospital started an innovative project in 2009, in the form of Home Care for MDR Patients and it concluded with Long-term Follow-up of patients, who had received DOTS Plus Treatment along with Home Care and Counselling (2015). Aims: To study the spectrum, severity and the risk factors for ADRs in MDR-TB patients. Methods: In this retrospective study files of 109 MDR-TB patients who had received treatment along with home care and counselling support, were reviewed. The study was conducted between January to May 2024. Results: Out of 109 MDR TB patients there were 68 (62%) developed one or more ADR. Joint pains 44(40.36%), was the most commonly observed ADR, followed by nausea 29(26.6%) and vomiting 25(22.93%), weakness 23(21.1%), anxiety and depression 16(14.67%), difficulty in breathing 14(12.84%), tremors 13(11.9%), giddiness 11(10.1%), skin rashes 10(9.2%). According to Hartwig Scale mild ADRs were 58.8%, moderate 5.9% and severe 35.3%. Patients who had BMI <18.5 experienced less ADRs with an Odds Ratio =0.22; 95% CI=0.06 to 0.72, p=0.0124. Unemployment was associated with higher number of ADRs OR=3.5; 95% CI=0.99 to 12.29, p=0.05. Sixty-two % MDR TB patients had ADRs. Our treatment outcomes showed 41(60.3) as cured, 24(35.3) died, 2(2.9) defaulted and 1(1.5) failed treatment. This was possible because healthcare teams counselled and provided all possible support to patients 24x7 thus improving adherence to therapy. Conclusion: ADRs occurred in more than half of the cases, with joint pain being the most common. Interventions such as counselling of patients and their family on importance of adherence to drugs at the initiation of treatment, provision of nutritional support, psychological counselling and motivation, instant referral for ADRs and care of patients at referred facilities, help patients not becoming defaulters.
Hay diseases in Iceland
Authors: Gislason David , Asmundsson Tryggvi
Published: July 2024

Diseases due to work in hay dust have long been known in Iceland and the first written records of them appear in the beginning of the 17th century. At the end of the 18th century, a district doctor alleges that they cause many deaths in the country. In the latter part of the 20th century, research was started to investigate the causes and nature of hay diseases in Iceland. Studies of allergens showed high levels of storage mites in hay. Highest levels were of Tarsonemus sp., Acarus farris and Lepidoglyphus destructor. A several micro-fungi were also found, most commonly Rhizopus sp., Penicillium sp. and Aspergillus sp. Micropolyspora faeni was also found in all hay samples. A study was done on people aged 6-50 years in two districts in Iceland. In one district farmers used almost exclusively dry hay and in the other they used 80-90% silage. There was no difference in IgE-mediated allergy between the provinces, but most had positive skin tests for L. destructor and cattle. Those with symptoms connected with hay dust most often reported nasal symptoms (79%), eye symptoms (63%), cough (41%), dyspnea (32%) and fever (21%). Those who had positive skin reaction complained most often of nose and eye symptoms. A study was also conducted on subjects aged 16-87 years from the same regions investigating precipitin tests for M. faeni, Thermoactinomyces vulgaris and Aspergillus fumigatus. Pulmonary symptoms and lung function were also investigated. Precipitin tests were almost exclusively positive for M. faeni, and 5 individuals were positive for A. fumigatus and none for T. vulgaris. The precipitin tests were significantly more often positive in those working almost exclusively with dry hay (72.9% vs. 23.9%). They had also more commonly obstructive pulmonary disease (FEV1/FVC%<70: 24.8% vs. 9.5%) as well as dyspnea when walking on level ground. There was a positive correlation between positive precipitin tests for M. faeni and dyspnea walking on level ground. The sensitivity and specificity of positive precipitin tests for M. faeni were investigated to detect farmer’s lung. The sensitivity was 82% and specificity was only 49%. A survey of emphysema in patients in the only Pulmonary Clinic in the country showed that farmers had more often emphysema than the rest of the country population, and 58% of farmers with emphysema had smoked compared to 94% of other emphysema patients.
Treating Chronic Pain and Anxiety – a Modest Proposal
Authors: Lawhern Richard , Nadeau Stephen
Published: July 2024

Introduction: the CDC guidelines of 2016 and 2022 strongly proscribed the co-prescription of opioids and benzodiazepines, implicitly suggesting that the combination was associated with high risk. This position now strongly influences health provider organizations, clinicians, pharmacies, health insurance companies, and boards of medicine. We have previously comprehensively reviewed the generally high-quality published studies, all employing a retrospective cohort design. These studies suggest that, to the extent that the combination increases mortality risk, the magnitude of the increase is small and it likely reflects a conflation of mortality risk related to the underlying conditions and the risks associated with simultaneous use of drugs of both classes. We here recapitulate the results of our prior analyses, contrast them with CDC positions, and introduce the results of additional studies, some only recently published and some of which we had previously been unaware.

Published: July 2024

Background and Objectives: Despite its extensive utilization, research on Chat Generative Pre-trained Transformer (ChatGPT)'s potential negative impact on specific cognitive processes is scarce. This article explores the widespread use of ChatGPT in educational, corporate, and various other sectors, focusing on its interaction with distinct cognitive domains such as attention, executive function, language, memory, visuospatial abilities, and social cognition. Methods: A literature review was conducted using PubMed, identifying 256 articles, with 29 peer-reviewed articles analyzed after screening for relevance. Results: The review emphasizes the extraordinary capabilities of the human brain, which often go unrecognized, and argues for the importance of maintaining and enhancing natural cognitive abilities using artificial intelligence tools like ChatGPT as an aid rather than a replacement. The findings highlight the advanced reasoning capabilities of ChatGPT, blending intuitive and deliberate cognitive processes. Conclusion: Building a socio-cognitive architecture for collective human-machine intelligence has significant potential. While ChatGPT offers impressive capabilities, over-reliance on it for cognitive tasks can lead to the erosion of essential skills. It is crucial to find a balance between leveraging artificial intelligence's advantages and preserving our natural cognitive abilities, ensuring continuous practice and engagement in traditional cognitive exercises.
Current Landscape of Patients with Metastatic Cancers in the Philippines
Authors: Ting Frederic , Uy Crizel , Berba Carlo , Sacdalan Dennis
Published: July 2024

Globally, cancer imposes an extensive burden in terms of both epidemiology and financial adversity. Treating cancer remains a challenge despite outstanding development in the field of molecular oncology. The introduction of sophisticated imaging and diagnostic technologies and novel targeted therapies are leading to expensive treatment which is unaffordable to most patients. These challenges strain the already weak healthcare and economic infrastructure of the low- and middle-income countries, where resources are already constrained and access to health care is suboptimal. Thus, it is critical to focus on the prevention strategies that intend to control the rising burden of cancer. Screening programs have long been proven to be cost-effective in reducing cancer mortality by detecting malignancies at earlier asymptomatic stages and thus should be on top priority in the public health agenda of the Philippines. This review paper aims to explore the status of metastatic cancers in the country, including its epidemiology, the current diagnostic and treatment landscape, and future directions to reduce the cancer burden.
Opsoclonus-Myoclonus Syndrome in a Child with Birth Asphyxia
Authors: Daga Subhashchandra
Published: July 2024

A case of Opsoclonus Myoclonus Syndrome associated with birth asphyxia presented with antiseizure treatment started soon after birth and continued after discharge. The child presented at two years of age and had jerky movements in the limbs and eyes. The eye movements promptly responded to phenobarbital, and the limb movements appreciably diminished after adding clonazepam. The practice of continuing antiseizure treatment post-discharge in asphyxiated babies is questionable. No asphyxiated baby is reported in the literature to have OMS.
Herbal Nephropathy and Balkan Endemic Nephropathy: The Pathogenic Role of Aristolochic Acid
Authors: Ioannis Koulouridis , Efstathios Koulouridis , Qari Maha
Published: July 2024

Aristolochic acid nephropathy is a worldwide iatrogenic disease affecting individuals consuming herbal remedies derived from Aristolochia and Asarum species. The disease is characterized by prominent renal atrophy and extensive interstitial fibrosis. A considerable proportion of patients, about 30-45 % develop also transitional cell carcinoma mainly of the upper urinary tract. A special attention to the disease was paid in early 90’s because of an epidemic of rapidly progressive interstitial nephropathy affecting young women consuming slimming pills, containing Chinese herbs, supplied from the same clinic in Brussels, Belgium. Detailed investigation of slimming pills showed that they inadvertently contained Aristolochic acid considered as the causative factor of the disease. Soon thereafter it was showed that another devastating chronic interstitial nephropathy accompanied also with increased incidence of upper urothelial cancer, known as Balkan Endemic Nephropathy, is the result of chronic intoxication of affected individuals with low doses of Aristolochic acid derived from the soil contamination from the plant Aristolochia clematitis. Although Aristolochic acid has already characterized as class I carcinogen for humans, Aristolochia species continues to be used as herbal remedies especially in Asia countries and China as well as in westernized communities. It is noteworthy that although Aristolochia species are used as herbal remedies since antiquity there are no references for nephrotoxicity and carcinogenicity until the Belgium epidemic. In this review article we attempt to elucidate the historical evolution of our knowledge upon the etiology of Aristolochic acid nephropathy as well as the underlying mechanisms of Aristolochic acid cytotoxicity.
Instant TV. The Forgotten History of Video Tape Recording (and the Coverage of the Eichmann Trial)
Authors: Keilbach Judith
Published: July 2024

This article adopts a media archaeological approach to the Eichmann trial (1961) to explore the technology and media constellations that enabled its global television coverage. Drawing on extensive archival research, it offers insights into the technological setup and institutional cooperation crucial for the broadcast. In this context, video tape recording played a pivotal role, facilitating instantaneous reporting from around the world. Informed by actor-network theory, the article highlights the interplay of different (non)human actors who were interested and enrolled in a short-lived actor-network that soon became obsolete with the advent of communication satellites. Through recounting the story of the trial coverage, it not only recalls the forgotten use of a technology but also sheds light on emerging television formats and infrastructures that persisted far beyond the brief prominence of Instant TV.

Published: July 2024

This research presents the push-pull factors of refugees and asylum seekers towards Europeancountries during strong domestic resistance by The Visegrad Group, consisting of Hungary, Poland,Slovakia, and the Czech Republic. These factors were examined using the push-pull migration theory,and the results are presented qualitatively. The data and information presented in this paper came fromsecondary sources. The findings revealed two significant facts. Firstly, the negative conditions in thehome countries of refugees and asylum seekers act as migration drivers, including prolonged conflicts,economic crises, and limited job opportunities; secondly, the attractiveness of Europe as a regioncharacterized by safety, a stable economy, availability of resources, and sufficient job opportunities.

Published: June 2024

Background: B-cell prolymphocytic leukemia (B-PLL) is a rare disease, consisting <1% of mature B-cell malignancies. B-PLL is often refractory to chemotherapy, with a median survival of 3 years. Due to its rarity, no large cohort studies exist elucidating outcomes.
Methods: All B-PLL patients >15 years were identified in the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) database between 2000-2020. Statistical analysis explored demographic variables like age; categorized as adolescent or young adult (AYA) and adults. In adults, differences in survival due to factors such as sex, race/ethnicity, household income, rurality, and age categorized in 10-15 year buckets was analyzed.
Results: B-PLL patients were predominantly white (78%), over 40 years (96%) and mostly residing in metropolitan areas (90%). Interestingly, the AYA cohort were mostly female (70%). 35% of the AYA patients were Hispanic, while being only 9% in adults. Among adults, the rate of Asian/Pacific-Islander patients that were alive at the time of the data query was 53% compared to 34% in Hispanic, 31% in black, and 24% in white patients (p=0.025). Younger age was also associated with greater chances of survival (p<0.001).
Conclusions: In line with known poor prognosis of the disease, 23% patients were alive at the time of data query. Female and Hispanic patients were overrepresented in the AYA age group. In the adult group Asian/Pacific-Islander patients had better survival outcomes, as did younger patients. Further research is necessary to explore why B-PLL incidence in AYA patients is higher among Hispanic and females.
