Cervical cancer is a significant global health challenge, disproportionately impacting women in developing nations, where approximately 85% of incidence and mortality occur. The primary etiological agent is the human papillomavirus (HPV), with high-risk types HPV 16 and 18 accounting for over 90% of cases. Despite the high prevalence of HPV, most infected women do not develop cervical cancer, indicating the role of additional risk factors. Objective: This study aims to investigate the association between various sociodemographic and behavioral factors, HPV infection, and the progression of cervical cancer. Methods: This case-control study was conducted at the Cancer Care Hospital and Research Center in Pakistan from April 2024 to April 2024. It involved 200 consecutive subjects, with 100 cases diagnosed with precancerous lesions (HSIL/LSIL) or invasive carcinoma of the uterine cervix, and 100 age and ethnicity-matched controls with normal cervical cytology. Data were collected through structured personal interviews and analyzed using descriptive and inferential statistical methods. The significance level was set at p < 0.05. Results: Significant differences between cases and controls were observed in dietary habits, gravidity, parity, age, menopausal status, residential setup, tobacco chewing, smoking, and age at marriage. Non-vegetarian diet, higher gravidity and parity, older age, postmenopausal status, rural residence, tobacco use, and early marriage were significantly associated with increased cervical cancer risk (p < 0.0001). No significant difference was found in literacy rates (p = 0.68). Conclusion: The study highlights the multifactorial etiology of cervical cancer, emphasizing the need for targeted interventions addressing specific risk factors. Early detection, HPV vaccination, and public health education, particularly in rural areas, are crucial for reducing cervical cancer burden.

Published: July 2024

Neurotransmitters and hormones work together in a complex way in the body to control mental and physical processes. Objective: To focus on dopamine, a crucial neurotransmitter produced by mesencephalic neurons in both the brain and peripheral organs. Methods: The study was conducted on albino rats weighing 180-200 gm. The rats were introduced into the new apparatus designed with the measurements of 40 x 40 cm in length, 25 x 25 cm in breadth, and 30 cm in height on all four sides. All sides were painted black except one mounted with (Light Emitted Diode) LED display. Rats were shown the screen for 1 hour daily for 30 minutes with high pixel resolutions and bright colors. The tested group was then compared with the control group on the 30th day on the parameters of gross behavior, biogenic amines of brains, and brain histopathology. Results: The results showed anxiety and hyperactive behavior in gross studies. Biogenic amines showed an increase in 2-amino 5-methyl benzoic acid that is the dopamine precursor. The study indicated that low levels of pyrrolidine, which decreased (Gamma Aminobutyric Acid) GABA in the brain, ultimately caused sleep disorders. Histopathological studies also showed the degeneration of neuronal cells in tested brains compared to control. Conclusions: The changes found in rats might be useful in determining the drawbacks of using mobiles, tabs, and other screen time

Avian Flu: A Looming Threat to Global Health Security
Authors: Qadir Muhammad Farhan
Published: July 2024

Avian influenza A (H5N1), a highly pathogenic virus, known as bird flu is emerging as a serious global health security risk. Avian flu subtypes H5N1 and H7N9 circulate in bird populations worldwide with high genomic diversity and the ability to reconstruct with the human influenza virus to introduce new strains capable of zoonotic (human-to-human) transmission. Influenza virus evolves and develops new pathogenic strains very rapidly. Around 50 million people died due to the 1918 'Spanish flu' pandemic caused by an H1N1 influenza virus [1]. In addition to the H1N1 pandemic (Swine flu) in 2009, there have been a few other human AIV pandemics in the past decades: the H2N2 pandemic (Asian flu) in 1957 and the H3N2 pandemic (Hong Kong flu) in 1968 [2].
The H5N1 outbreak not only infects birds but also breaks and crosses the interspecies barrier and affects mammals including animals and humans.  H5N1 virus has limited human transmission because it binds to alpha-2, 3-linked sialic acid receptors (during its replication cycle) which are less abundant in the human respiratory system as compared to birds but its genetic reassortment ability makes it highly pathogenic and a health hazard for humans. The outbreak of the H5N1 virus has been reported currently in US dairy cows and workers. In humans, it can cause severe respiratory problems, multi-organ failure, and high mortality rates. Four humans have been affected since 2020 in the US [3]. The Centers for Disease Control and Prevention (CDC) is thoroughly monitoring the people with animal exposure, carefully inspecting the situation, and currently reporting a low public health risk. Experts are raising alarm about the transfer of viruses from birds to humans and are urging the implementation of new protocols for handling airborne infectious diseases. However, the worldwide spread of H5N1 and its ability to infect mammals causes major threats regarding the potential for human-to-human transmission, which may result in a pandemic. In addition to its potential impact on human health, bird flu poses an immense threat to agriculture and food security because of its economic implications.
As the avian flu continues to pose a persistent and evolving threat to global health security, national, regional, and global vigilance, preparedness, and collaborative actions are needed. It is important to maintain robust surveillance, respond rapidly, and innovative prevention and control strategies due to sporadic outbreaks of avian flu. Management of avian flu demands a coordinated effort to protect human and animal health, mitigate economic impacts, and improve the global health security
From coast to coast

Published: July 2024

The present work stems from the attempt to give answers to some questions commonly asked by those who approach the study of material culture, i.e. what can be a modern and effective methodological approach to the study of objects, especially ceramics, found in an archaeological excavation? How can we derive useful information for the economic and social reconstruction of the ancient world from the classification and chronotypological analysis of pottery and special objects? These are the questions underlying the research project developed as part of the activities carried out for the PhD at the Free University of Amsterdam between 2018 and 2021, questions that start precisely from the study conducted on material found in some sample sites located in the Strait of Otranto, both in Apulia and Albania. Here, in fact, the constant and continuous relations between the two sides of the Ionian-Adriatic basin have sedimented in a series of traces which, at different times and in different ways, have contributed to the ethnic, cultural, economic and social definition of those who live and have lived in these territories. Within this area, the Otranto canal is both the gateway to the "cul de sac" that is the Adriatic Sea and the passageway linking it with the central-eastern Mediterranean..

Authors: Whardana Adithya Kusuma , Hadi Rentelinggi Parma
Published: July 2024

Due to factors such as a growing population, more people using private vehicles, and outdated transportation infrastructure, Jakarta, the capital city of Indonesia, suffers from chronic traffic congestion. The environment, citizens' safety, productivity, and quality of life are all negatively impacted by these interruptions. In response to these difficulties, this study proposes a novel method for traffic monitoring. By combining YOLOv5, optical flow, and recurrent neural networks (RNN) with image processing and artificial neural networks, a unified traffic monitoring system can be achieved. We went with YOLOv5 because of how well it identifies various automobiles. The number of vehicles is counted between video frames using Optical Flow, and then the traffic density is classified using RNN. With an accuracy of 87% following testing, RNN was clearly a winner when it came to vehicle density classification. The goals of this research are to lessen the societal and environmental toll of traffic congestion, increase our knowledge of and ability to control Jakarta's traffic, and lay the groundwork for the creation of more advanced traffic monitoring systems. The growing traffic issues in the nation's capital are anticipated to be alleviated with this strategy.

Authors: Sulistiyowati Indah , Ichsan Hafidz Maulana , Anshory Izza
Published: July 2024

The OpenCV Python library has been developed in all technology fields, including the industrial sector. In the industrial world, there are objects sorting tools in the form of conveyors. These instruments are presently more advanced since they employ cameras to read the things that should be sorted. The purpose of applying the Open Source Computer Vision Library (OpenCV) system to this object’s sorter conveyor is to make it easier to sort objects based on color detection technology. The OpenCV method for object detection based on color was employed to select those objects. The first step in identifying the object in question is to capture RGB (red, green, and blue) objects in real time and transform their colors into HSV. Additionally, by masking the object to be centered and applying a threshold, the morphological process can remove unnecessary noise from the image. The investigation results include the ability to differentiate objects based on RGB color when sorted by considering the HSV value on the surface of colored objects.
Decision-Making in Gripper Control Systems Using Fuzzy Logic Method and Telegram Application
Authors: Watiasih Richa , Cosabagus Junior Risqy
Published: July 2024

The application of the gripper in the industrial world has facilitated human work in the sorting process but has the disadvantage of not being able to sort objects based on the object's color. Conditions like these can affect the production quality factor when sorting objects. This research resulted in a gripper end effector system using the fuzzy method and the telegram application as a control, which has a function to distinguish the color of objects gripped by the gripper, thereby minimizing errors in sorting objects based on color. Telegram is used because the application is relatively light and can be accessed anywhere as long as it is connected to an internet connection. This study uses the fuzzy logic method as a decision-making process. The fuzzy method is used because it is very flexible and has a tolerance value in the existing data. The telegram function in this study is the main control to give orders to the gripper. The TCS3200 color sensor, in this study, is used to detect object color. The TCS3200 sensor converts the light intensity value to 8 bits so that the microcontroller can read it for each color in the test. The colors red, green, and blue were chosen as a reference because they are the primary or basic colors of all colors. From the results of testing the entire system in this study, 90% success was obtained in moving objects precisely based on the object's color. This result is enough to prove that the system can work properly.

Published: July 2024

The picture of the world that Leibniz proposes in his doctrine is undeniably remarkable. The created world we inhabit is, according to Leibniz, the best all possible worlds. And the world is the best because it is the masterpiece of the most perfect architect: God. God, who possesses all qualities and attributes in the highest degree, could only have acted in the best possible way in creation. According to Leibniz, such a noble task as the creation of the world could only have fallen to the supreme Being. Inspired by tradition and motivated by the resolution of metaphysical and theological questions, Leibniz attempted at many places in his teaching to provide evidence for God‘s existence and his infinite goodness. The aim of this work is to analyse and clarify the concept of God and his creation within the thesis of the best of all possible worlds in the philosophy of G. W. Leibniz.

Published: July 2024

In recent years, there has been a global challenge in developing MPPT algorithms that provide maximum power efficiency. This paper deals with a novel P&O-PI MPPT mechanism where the soft computing technique called particle swarm optimization (PSO) is used to tune the PI parameters. The proposed approach was designed to improve the tracking response time of MPP with high efficiency. This MPPT is applied to two types of PV systems: tracking systems and fixed systems. The energy gain of a dual-axis tracker was compared to that of a fixed system. Simulation results were carried out in Matlab and Simulink environments to demonstrate the effectiveness of the suggested control strategy in terms of productivity, efficiency, and oscillations under different fast environmental conditions. We can see that the recommended technique shows excellent performance in terms of power overshoot, low oscillation, and response time. The PSO-P&O-PI-algorithm offers a considerable improvement in tracking efficiency of 99.90% and a time response of 0.023 s. We have demonstrated the significance of involving the sun-tracker PV system regarding produced power (acquired power) with around 25% energy gain, particularly during the less sunny hours.

Downscaling of wind speeds with the Weather Research and Forecasting model (WRF) model requires inputs from datasets such as Meteorological and Land Use and Land Cover (LULC) datasets. The accuracy of these datasets is among the factors that significantly impact the accuracy of the wind speeds that are generated by the model. In this study, we assess the accuracy of wind speeds data that are downscaled for an area in coastal Ghana using six meteorological, and two global Land use and Land Cover (LULC) datasets as inputs to the WRF model. In contrast to the LULC datasets tested, model wind speeds for the area were more significantly impacted by the different meteorological datasets. Meteorological datasets that were produced with higher resolution forecasts combined with more advanced data assimilation techniques produced better estimates of wind speed, and vice versa. The JMA JRA55 Reanalysis, NCEP GFS Analysis data, and ECWMF ERA5 gave the relatively best combinations of wind speed error metrics and are therefore recommended for consideration for downscaling of wind speeds for wind resources assessment in the coastal regions of Ghana. However, the ECWMF ERA5 is preferred as its mean error margins are fairly constant and so should be easier to correct.

BACKGROUND

Traumatic brain injury (TBI) imposes a substantial societal and familial burden due to its high disability and fatality rates, rendering it a serious public health problem. Some patients with TBI have poor treatment outcomes and are prone to postoperative delirium (POD), which affects their quality of life. Anxiety has been linked to increased POD incidence in some studies, while others have found no correlation.

AIM

To investigate the correlation of POD risk factors, preoperative inflammatory factors, and mood disorders in patients with TBI.

METHODS

We retrospectively collected data on the treatment of 80 patients with TBI from November 2021 to September 2023. Patients were grouped as POD and non-POD, according to their POD status, and the general data of the two groups were compared. Inflammatory factor levels were detected preoperatively, and the Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) were used to investigate the risk factors associated with POD in these patients. Logistic regression was used to identify the independent risk factors.

RESULTS

Twenty-one patients (26.25%) developed POD, including 7, 10, and 4 cases of the excitatory, inhibitory, and mixed types, respectively. There were 59 cases (73.75%) in the non-POD group. Compared with the non-POD group, the POD group had a significantly higher proportion of patients with low Glasgow Coma Scale (GCS) scores before admission, unilateral mydriasis, preoperative hemorrhagic shock, intraventricular hemorrhage (IVH), and postoperative hyperglycemic hyperosmolar disease (P < 0.05). In the POD group, interleukin-6 (IL-6), human tumor necrosis factor-α (TNF-α), myeloperoxidase levels, HAMA, and HAMD scores were higher than those in the non-POD group (all P < 0.05). Logistic multivariate analysis showed that GCS score at admission, IVH, IL-6, TNF-α, HAMA, and HAMD were independent risk factors for POD in patients with TBI (P < 0.05).

CONCLUSION

Low GCS score at admission, IVH, elevated IL-6 and TNF-α, other inflammatory indicators, anxiety, and depression, can increase the risk of POD in patients with TBI after surgery.
Beyond surgery: Overcoming postoperative depression in cancer patients

Depression is a common occurrence among cancer patients, and it significantly impacts their clinical outcomes and quality of life, with a high incidence during anti-tumor treatment or after surgery. The association between surgery and depression is the result of the interaction of various factors, including physiological, psychological, and social factors, all of which are intertwined and make patients susceptible to depression after surgical treatment. Postoperative depression has a significant negative impact on many aspects of cancer patients, and it requires timely identification and intervention to improve the overall outcome.

Published: July 2024

BACKGROUND

Cognitive-behavioral therapy (CBT) and habit reversal training (HRT) have shown application potential in addressing tic symptoms and comorbid psychiatric conditions. Despite their theoretical potential, empirical evidence on their combined efficacy remains limited.

AIM

To evaluate the efficacy of CBT combined with HRT on anxiety disorders in children with Tourette’s syndrome (TS).

METHODS

Clinical data of children with TS admitted to our hospital from January 2022 to June 2023 were collected, and the patients were grouped into the conventional therapy (control) group and the CBT combined with HRT group. Baseline characteristics, anxiety scores, tic severity scores, treatment adherence, and parental satisfaction were assessed. Statistical analysis was performed using t-tests, chi-square tests, and correlation analysis.

RESULTS

A total of 136 patients, including 65 patients in the control group and 71 patients in the CBT combined with HRT group, were included. The CBT combined with HRT group showed remarkable improvements compared with the control group. Post-intervention assessment revealed a decrease in anxiety scores from 63.52 ± 1.81 to 40.53 ± 1.64 (t = 2.022, P = 0.045), and the Yale Global Tic Severity Scale total score decreased from 22.14 ± 5.67 to 16.28 ± 4.91 (t = 2.288, P = 0.024). Treatment adherence was significantly higher in the CBT combined with HRT group (85.47 ± 7.62%) compared with the control group (82.32 ± 6.54%; t = 2.596, P = 0.010). Parental satisfaction scores were also higher in the CBT combined with HRT group (8.69 ± 1.77) compared with the control group (7.87 ± 1.92; t = 2.592, P = 0.011).

CONCLUSION

This study demonstrates that CBT combined with HRT significantly reduces anxiety symptoms and tic severity in children with TS, with higher treatment adherence and parental satisfaction. These findings support the potential application of this comprehensive therapeutic approach for TS treatment.
SEPARAR PARA CONTROLAR: OS SENTIDOS DA COMIDA NA CEAGESP DE SÃO PAULO/SP

Desde as mais antigas formas de comercialização de alimentos, como as feiras-livres, até a consolidação das grandes cadeias nacionais e internacionais de abastecimento, as distâncias necessárias ao encontro entre produção e consumo têm sido progressivamente aumentadas, com implicações no aumento dos preços e, consequentemente, na redução do acesso aos alimentos, sobretudo para as famílias mais pobres. Nesse âmbito, este artigo tem como objetivo analisar os significados da CEAGESP de São Paulo/SP para o abastecimento alimentar hortifrúti, de maneira a destacar as estratégias de separação e controle perpetradas pelo capital comercial e industrial. Para isso, foi realizada uma revisão bibliográfica sobre o assunto, com especial atenção para os conceitos de regimes alimentares internacionais e impérios alimentares. Além disso, foram realizados trabalhos de campo na CEAGESP de São Paulo/SP e no município de Piedade/SP. Antes de articular produção e consumo, os atravessadores instalados nas centrais de distribuição têm a sua existência assegurada na constante separação entre os extremos da alimentação, de maneira cobrar pelo encontro entre ambos. Portanto, faz-se necessário questionar o atual sistema de produção e distribuição de alimentos, de maneira a pensar estratégias para a construção de uma alimentação emancipada do jugo dos atravessadores.
PALAVRAS-CHAVE: Regimes alimentares internacionais; Impérios alimentares; Centrais de abastecimento; Hortifrútis.

This study investigated the valorization of agro-industrial solid waste for biohythane production through a two-stage anaerobic digestion process. Seventeen waste samples were characterized, revealing diverse physico-chemical properties suitable for anaerobic digestion. The highest biohythane yields were obtained from waste-activated sludge (WAS) from a frozen convenience food wastewater treatment plant (895.63 mL/g VS), WAS from a processed chicken wastewater treatment plant (835.73 mL/g VS), and WAS from a municipal wastewater treatment plant (830.79 mL/g VS). Kinetic analysis using the modified Gompertz model provided insights into the biohythane production potential, with predicted yields ranging from 0 to 111.85 mL/g VS and production rates from 0 to 21.37 mL/d. The comparative analysis highlighted the superior biohythane production potential of the studied waste materials compared to other substrates, such as food waste (180.5 mL/g VS) and sugarcane bagasse (165.2 mL/g VS). The highest hydrogen and methane contents in the produced biohythane were 26.57% and 67.85%, respectively. The techno-economic assessment of scaled-up biohythane production demonstrated the economic feasibility, with a payback period of 2.05 years for a plant capacity of 100 ton waste/day, a biohythane yield of 500 m3/ton waste, and a biohythane production of 50,000 m3/day. The capital cost was estimated at 15 million USD, with an operating cost of 0.2 USD/m3 biohythane and a revenue of 0.6 USD/m3 from biohythane sales. The results of this study demonstrate the high potential of agro-industrial solid waste valorization for biohythane production and its contribution to sustainable waste management and renewable energy production.
