Current ARTs, Virologic Failure, and Implications for AIDS Management: A Systematic Review
Authors: Foka Frank Eric Tatsing , Mufhandu Hazel Tumelo
Published: August 2023

Antiretroviral therapies (ARTs) have revolutionized the management of human immunodeficiency virus (HIV) infection, significantly improved patient outcomes, and reduced the mortality rate and incidence of acquired immunodeficiency syndrome (AIDS). However, despite the remarkable efficacy of ART, virologic failure remains a challenge in the long-term management of HIV-infected individuals. Virologic failure refers to the persistent detectable viral load in patients receiving ART, indicating an incomplete suppression of HIV replication. It can occur due to various factors, including poor medication adherence, drug resistance, suboptimal drug concentrations, drug interactions, and viral factors such as the emergence of drug-resistant strains. In recent years, extensive efforts have been made to understand and address virologic failure in order to optimize treatment outcomes. Strategies to prevent and manage virologic failure include improving treatment adherence through patient education, counselling, and supportive interventions. In addition, the regular monitoring of viral load and resistance testing enables the early detection of treatment failure and facilitates timely adjustments in ART regimens. Thus, the development of novel antiretroviral agents with improved potency, tolerability, and resistance profiles offers new options for patients experiencing virologic failure. However, new treatment options would also face virologic failure if not managed appropriately. A solution to virologic failure requires a comprehensive approach that combines individualized patient care, robust monitoring, and access to a range of antiretroviral drugs.

Ursodeoxycholic acid (UDCA) was demonstrated to reduce susceptibility to SARS-CoV-2 infection in vitro and improve infection course in chronic liver diseases. However, real-life evidence is lacking. We analyzed the impact of UDCA on COVID-19 outcomes in patients hospitalized in a tertiary center. Between January 2020 and January 2023, among 3847 patients consecutively hospitalized for COVID19, 57 (=UDCA group) were taking UDCA. The UDCA and the control groups (n = 3790) did not differ concerning comorbidities including diabetes mellitus type 2 (15.8% vs. 12.8%) and neoplasia (12.3% vs. 9.4%). Liver diseases and vaccination rate were more common in the UDCA group (14.0% vs. 2.5% and 54.4% vs. 30.2%, respectively). Overall mortality and CPAP treatment were 22.8 % and 15.7% in the UDCA, and 21.3% and 25.9% in the control group. Mortality was similar (p = 0.243), whereas UDCA was associated with a lower rate of CPAP treatment (OR = 0.76, p < 0.05). Treatment with UDCA was not an independent predictor of survival in patients hospitalized for COVID-19.

HCC, the most prevalent form of primary liver cancer, presents a substantial global health challenge due to its high mortality and limited therapeutic options. This review delves into the potential of cancer vaccines as a novel therapeutic avenue for HCC. We examine the various categories of cancer vaccines, including peptide-based, dendritic cell-based, viral vector-based, DNA, and mRNA vaccines, and their potential application in HCC management. This review also addresses the inherent challenges in vaccine development, such as tumor heterogeneity and the need for identifying tumor-specific antigens. We underscore the role of cancer vaccines in reshaping the immune environment within HCC, fostering durable immune memory, and their potential in combination therapies. The review also evaluates clinical trials and emphasizes the necessity for more extensive research to optimize vaccine design and patient selection criteria. We conclude with future perspectives, highlighting the significance of personalized therapies, innovative antigen delivery platforms, immune modulatory agents, and predictive biomarkers in revolutionizing HCC treatment. Simple Summary: This review explores the potential of cancer vaccines as a promising therapeutic strategy for hepatocellular carcinoma (HCC), a prevalent and deadly liver cancer. The authors discuss various types of cancer vaccines, their challenges, and their role in modulating the immune response within HCC. They also highlight clinical trials and future perspectives, emphasizing the importance of personalized therapies, novel antigen delivery platforms, and predictive biomarkers.

Published: August 2023

Rubella is an infectious disease caused by the rubella virus. Congenital rubella syndrome is a risk for all newborns if pregnant women are infected with rubella, raising an important public health issue. Rubella is a vaccine-preventable disease, and routine immunization has been conducted in Japan. The timing of the vaccine approval did not differ from that in the United States. In 2004, endemic rubella was eliminated in the United States. However, recent rubella outbreaks have occurred in Japan. This may be related to differences in the introduction of routine rubella immunization. In Japan, routine rubella immunization was initially introduced only for junior high school girls, and the rate of susceptibility is high among males who have not received rubella vaccination, causing an outbreak. Therefore, in Japan, measures have been taken to decrease the number of susceptible males in the vaccination-free generation. The coronavirus pandemic has also affected the epidemiology of rubella as well as other infectious diseases.

Respiratory disease continues to be the major cause of mortality in feedyard cattle, with bronchopneumonia (BP) and acute interstitial pneumonia (AIP) as the two most common syndromes. Recent studies described a combination of these pathological lesions with the presence of AIP in the caudodorsal lungs and BP in the cranioventral lungs of necropsied cattle. This pulmonary pathology has been described as bronchopneumonia with an interstitial pneumonia (BIP). The epidemiological characteristics of BIP in U.S. feedyard cattle are yet to be described. This study’s objectives were to describe the agreement between feedyard clinical and necropsy gross diagnosis and to characterize epidemiological factors associated with four gross pulmonary diagnoses (AIP, BIP, BP, and Normal pulmonary tissue) observed during feedyard cattle necropsies. Systemic necropsies were performed at six feedyards in U.S. high plains region, and gross pulmonary diagnoses were established. Historical data were added to the dataset, including sex, days on feed at death (DOFDEATH), arrival weight, treatment count, and feedyard diagnosis. Generalized linear models were used to evaluate epidemiological factors associated with the probability of each pulmonary pathology. Comparing feedyard clinical diagnosis with gross pathological diagnosis revealed relatively low agreement and the frequency of agreement varied by diagnosis. The likelihood of AIP at necropsy was higher for heifers than steers and in the 100–150 DOFDEATH category compared with the 0–50 DOFDEATH (p = 0.05). The likelihood of BIP increased after the first treatment, whereas the DOFDEATH 0–50 category had a lower likelihood compared with the 150–200 category (p = 0.05). These findings highlight the importance of necropsy for final diagnosis and can aid the development of future diagnosis and therapeutic protocols for pulmonary diseases.

Published: August 2023

Floods are the main natural disaster in Poland, and the risk of both fluvial and pluvial floods is serious in the country. Pluvial floods are on the rise in the changing climate, particularly in increasingly sealed urbanized areas. In this paper, we examine the changes in flood risk in Poland, discussing the mechanisms, observations, projections and variability. Next, we discuss flood risk management in the country, including specific issues related to urban and rural areas and the synergies between flood and drought risk reduction measures. We identify and assess the weaknesses of the existing flood risk management plans in Poland for the first planning period 2016–2021 and for the second planning period 2022–2027. We find the level of implementation of plans in the former period to be very low. Many planned measures do not have much to do with flood risk reduction but are often linked to other objectives, such as inland navigation. The plans contain numerous small measures, which come across as inapt and economically ineffective solutions. We specify policy-relevant recommendations for necessary and urgent actions, which, if undertaken, could considerably reduce flood risk. We also sketch the way ahead for flood risk management in Poland within the timeframe of the implementation of plans for 2022–2027 and the next regular update of plans for 2028–2033.

Published: August 2023

In order to explore bacteria resources that are applicable for purification of viaduct rainwater, a carbon-fixing bacteria strain numbered 1C-1 was isolated from the sediment of a viaduct rainwater tank. The strain was identified through morphological characteristics and 16S rDNA sequences. The effects of three main factors (the simulated viaduct rainwater concentration, the carbon source dosage, and the inoculation amount) on the nitrogen and phosphorus removal rate of the strain were tested using simulated viaduct rainwater. Based on this, the nitrogen and phosphorus removal efficiencies for the actual viaduct rainwater were verified. The results showed that the strain belonged to Streptomyces sp. Under different simulated viaduct rainwater concentrations, the strain exhibited relatively high efficiency for nitrogen and phosphorus removal at the original concentration of simulated viaduct rainwater; other conditions remaining unchanged, the purification efficiency was relatively high when the glucose dosage was 800 mg, and the removal rates of ammonia nitrogen (NH4+-N), total nitrogen (TN), and total phosphorus (TP) were 71.48%, 47.86%, and 10.43%, respectively; other conditions remaining unchanged, the purification efficiency was relatively high when the inoculation amount was 1%, and the removal rates of NH4+-N, TN, and TP reached 58.62%, 58.35%, and 27.32%, respectively. Under the above optimal process conditions of an original concentration of viaduct rainwater, a carbon source dosage of 800 mg, and an inoculation amount of 1%, the strain removed 92.62%, 6.98%, and 6.16% of NH4+-N, TN, and TP, respectively from the actual viaduct rainwater; more interestingly, the removal rates of NH4+-N and TN were 43.26% and 78.02%, respectively, even without carbon source addition. It seems that there is no need for carbon source addition to remove nitrogen from the actual viaduct rainwater for the strain. To sum up, the carbon-fixing bacteria 1C-1 presents an obvious nitrogen and phosphorus removal effect (especially for nitrogen) for viaduct rainwater treatment and has application potential.

Bottom-up management in a catchment scale is deemed the optimal way to avoid conflicts among water users through the participation of stakeholders, strategy co-shaping, and solutions co-creation. Water management cannot be one-dimensional; it demands cross sectoral cooperation. Usually, the difficulty lies in proper stakeholder training and inclusion of their opinions, which should be used in a quantifiable manner in water management. The Laspias River watershed occupies an area of 221.8 km2 that includes the River Basin District of Thrace; it is characterized by intense agricultural and industrial activity. To comply with the augmented water needs and pollution loads this research aims to utilize a hybrid intuitionistic fuzzy multi-criteria-based methodology to address respectfully stakeholders’ opinion, this research aims to utilize a hybrid intuitionistic fuzzy multi-criteria-based methodology. It is often difficult to manage planning water management measures as the problems include multiple (conflicting) criteria that are based on stakeholder’s opinions, which are usually imprecise and in a rather qualitative form. This study provides the mathematical tools to reach comprehensive decisions with the public involvement offering a practical solution in an existing problem, that is the proper inclusion of stakeholders’ opinion. The weights are produced based on a stakeholder’s opinion. The alternatives’ ranking is achieved based on the fuzzified intuitionistic version of the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), and a hierarchy of mitigation problems is achieved via this novel approach.
Influence of Anthropogenic Sulfuric Acid on Different Lithological Carbonate Weathering and the Related Carbon Sink Budget: Examples from Southwest China

Published: August 2023

Accurate estimate of carbonate weathering and the related carbon sink flux induced by anthropogenic H2SO4 is of great significance for improving understanding of the hydrogeochemical evolution and the global carbon cycle. Here, to quantitatively evaluate the influence of anthropogenic H2SO4 on different lithological carbonate weathering and the related carbon sink budget, karst spring water in the typical limestone and mixed limestone–dolomite catchments in Yaji and Beidiping affected by acid precipitation in southwest China were sampled monthly for the analysis of hydrochemical and δ13CDIC characteristics. Results show for the period of sampling (August 2013 to December 2014) that the average contribution rates of atmospheric inputs and carbonate weathering to total dissolved cations are 2.24% and 97.8%, and 3.09% and 96.9% in Yaji and Beidiping, respectively. The δ13CDIC values (−17.0% to −14.7‰) and the [Ca2+ + Mg2+]/[HCO3−] (0.98 to 1.25) and [Ca2+ + Mg2+]/[HCO3− + SO42−] (approximately 1) equivalent ratios of samples prove that H2CO3 and H2SO4 simultaneously participate in carbonate weathering. The contribution rates of H2SO4 to [Ca2+ + Mg2+] and [HCO3−] produced by carbonate weathering in Yaji and Beidiping are 0–30% and 0–18%, and 0–37% and 0–23%, with average values of 14% and 7%, and 19% and 11%, respectively, suggesting that the influence of H2SO4 on different lithological carbonate weathering is different. H2SO4 precipitation participating in carbonate weathering increases the weathering rate by 14–19%, whereas it decreases the flux of karst carbon sink by 7–11% in Southwest China. Therefore, anthropogenic acids have influenced the global carbon cycle and climate change by carbonate weathering due to the large karst areas in the world, and their influences on different lithological carbonate weathering should not be ignored in the regional and global carbon cycles in future studies.
Dimensionless Pressure Response Analysis for Water Supply Pipeline Systems with or without Pumping Station
Authors: Kim Sanghyun
Published: August 2023

Dimensionless governing equations of unsteady flow and solutions for the pipeline systems having a surge tank were developed. Frequency domain pressure response expressions for two widely used water supply systems were analyzed in dimensionless frequency and time domains. One is the simple reservoir pipeline surge tank valve system and the other is the pipeline system with pump and check valve protected by surge tank. Two different dimensionless expressions for the surge tank were developed and the performance of two expressions was compared. The frequency response pattern of impedance at the downstream valve indicated that the system resonance was determined by the lengths of the main pipeline and the connector and the locations of the surge tank and check valve for the protection of the pumping station. The difference between the simple pipeline system and that of a pump with a check valve was expressed in terms of the phase difference in frequency response distribution. The integrated pressure response for the protected pipeline section was evaluated considering the impact of surge protection in the frequency domain. A better understanding of system behavior can be obtained in terms of specific component isolation both in the frequency and time domain pressure responses. The driven responses in the frequency and time domain can be an important basis for optimum design and operation conditions of water supply systems in dimensionless space.

Authors: Das Kaushik , Kumar Roushan
Published: August 2023

The demand for electric two-wheelers as an efficient and environmentally friendly means of transportation has increased due to the rapid expansion in urbanization and growing environmental sustainability concerns. The electric two-wheeler ecosystem requires an ideal design solution that strikes a balance between numerous features, technologies, and specifications to meet these changing needs. In this study, we present an evaluation framework to find the best design for electric two-wheelers using novel Pareto optimality and TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) approaches. These solutions are then thoroughly assessed against predetermined criteria, such as energy efficiency, manufacturing viability, and market viability. Additionally, we incorporate the TOPSIS approach to order the non-dominated options according to how closely they resemble the best design solution. The design solution that best meets the required objectives while minimizing departures from the ideal state is identified using this procedure. Combining these approaches, our framework provides a more dependable and rigorous tool for evaluating the electric two-wheeler ecosystem, empowering producers and policymakers to choose the best design options. The findings show that the Pareto optimality and TOPSIS approaches efficiently identify the non-dominated options and make it easier to choose an ideal design solution that is in line with customer preferences and environmental sustainability. The results of this study support the development of electric two-wheeler technology and promote the use of environmentally friendly transportation options, thereby promoting a more sustainable future.

El papel de las instituciones en el desempeño de la pesca artesanal en Chapala
Authors: Vivar Arenas Josefina , Sandoval Moreno Adriana
Published: August 2023

Los pescadores artesanales de la Ciénega de Michoacán han sostenido una tradición lacustre ancestral transmitida por generaciones. Al parecer, la robustez de sus instituciones locales de pesca les ha propiciado márgenes de contención frente a los retos ambientales, sociales, económicos y normativos que experimentan en su territorio. En este estudio, analizamos la relación entre instituciones oficiales e instituciones locales que intervienen en el desempeño de la pesca artesanal en el Lago de Chapala. Desde un enfoque neoinstitucional, el objetivo del trabajo es problematizar la relación que existe entre las normas formales oficiales que regulan la actividad pesquera y las regulaciones tácitas locales que despliegan los pescadores para desempeñar su trabajo. Quién es pescador y quién no; cuánto se permite capturar y con qué avíos; dónde se permiten las capturas y cómo; cómo hacer las labores de la pesca, son algunas de las interrogantes estudiadas.

Mediante una estrategia cualitativa con entrevistas semi-estructuradas y un relevamiento de 27 perﬁles de diputados y senadores de Juntos por el Cambio, se busca explorar las diversas formas en que los cuestionamientos al patriarcado impactan en los discursos, roles y prácticas militantes del grupo. Paralelamente, este trabajo indaga las variadas expresiones de micromachismos, estereotipos, roles de género y privilegios en esa misma coalición. Finalmente, el artículo analiza las representaciones de los actores sobre la familia y la clase social, y la construcción de sus subjetividades masculinas. En este trabajo se observa cómo en los discursos de los varones de Juntos por el Cambio aparece una supuesta preocupación por la desigualdad de género, pero a su vez, no advierten ni identiﬁcan sus privilegios.

Pondok Pesantren (Ponpes) adalah suatu lembaga yang menghasilkan insan-insan yang dapat berkontribusi terhadap bangsa, negara dan agama.. Berkaitan dengan bidang keenergian, Ponpres dapat dijadikan basis mengubah pola fikir penggunaan energi fosil ke Energi Baru Terbarukan (EBT) sekaligus tempat pengembangan EBT.  Para santri memiliki posisi sangat strategis di mata masyarakat, karena pemahaman agama mereka sangat menunjang dan kata-kata mereka diikuti oleh warga. Oleh karena itu, mereka dapat dijadikan agen perubahan (agent of change) yang berpotensi merevolusi kondisi penggunaan EBT. Tantangan ini juga harus dijawab Ponpes Suryalaya. Media pembelajaran terkait energi baru terbarukan belum tersedia di Ponpes Suryalaya sehingga menjadi satu permasalahan tersendiri bagi pondok tersebut. Untuk menjembatani hal ini, dapat didukung dengan memberikan pengenalan wawasan, peningkatan skill dan penumbuhan pengetahuan serta pemahaman yang sesuai terkait dengan energi baru terbarukan (renewable energy). Kegiatan pengenalan dan pemahaman mengenai renewable energy ini bukan saja akan meningkatkan skill dan pengetahuan, tetapi juga sekaligus menjadi aktivitas strategis untuk menumbuhkan kesadaran dan kepedulian terhadap pemanfaatan sumber energi baru terbarukan.

Melalui program pengabdian pada masyarakat (P2M) yang diselenggarakan oleh Unit Penelitian dan Pengabdian Masyarakat (UPPM) Politeknik Negeri Bandung, tim P2M gabungan Jurusan Teknik Konversi Energi mengusulkan kegiatan pengenalan, sosialisasi  dan implementasi renewable energy, dikhususkan untuk Pembangkit Listrik Tenaga Surya (PLTS). Kegiatan yang diusulkan ditujukan untuk meningkatkan skill, membuka wawasan yang diharapkan akan menjadi bekal dan dimanfaatkan untuk meningkatkan potensi diri lulusan. Manfaat lain kegiatan adalah untuk meningkatkan kesadaran dan kepedulian pada energi terbarukan serta men-trigger kreativitas untuk pemanfaatannya dalam aplikasi kehidupan sehari-hari

Melalui metode sosialisasi secara teori di kelas dan praktek langsung pemberdayaan siswa SMK untuk memahami pengetahuan tentang teknologi surya dan teknik instalasi system PLTS berhasil di pahami. Hasil kegiatan sosialisasi menunjukkan terjadi peningkatan pemahaman pada para siswa rata-rata sebesar 20%.

Kebutuhan teknisi dalam bidang refrigerasi dan tata udara, akhir akhir ini sangat dibutuhkan mengingat dengan meningkatnya penggunakan alat alat pendingin dan juga tata udara. Perawatan alat/sistem refrigerasi dan tata udara menjadi meningkat pesat.  APITU merupakan sebuah perkumpulan teknisi dan merupakan singkatan dari Asosiasi Pendingin dan Tata Udara. Perkumpulan ini cukup meliputi seluruh Indonesai dan terstruktur mulai dari pusat, daerah, dan cabang. Saat ini untuk DPC Bandung, mempunyai anggota kira kira 50 orang, dan beranggotakan teknisi refrigerasi dan tata udara di sekitar Bandung Raya. Mereka umumnya belajar tentang refrigerasi dan tata udara secara otodidak ataupun dari seniornya, dan kadang menggunakan video yang tersebat di youtube, atau melalui diskusi di antara mereka dalam grup media sosial. Untuk itu diperlukan suatu kegiatan yang mampu memberdayakan teknisi tersebut, sehingga bisa lebih kompeten didalam menangani pekerjaannya. Untuk menjawab hal tersebut diatas, maka kemudian Jurusan Teknik Refrigerasi dan Tata Udara Politeknik Negeri Bandung (JTRA-POLBAN) melakukan sebuah kegiatan yang diharapkan kemudian mampu memberdayakan teknisi tersebut. Kegiatan ini berupa penyiapan bahan/alat untuk workshop/praktek, mentoring dan tutorial pembekalan keterampilan serta pelatihan terhadap teknisi berupa teori maupun praktek. Materi yang diberikan berupa, konsep sistem refrigerasi dan tata udara, prosedur standard pengopersian sistem refrigerasi dan tata udara, hal baru yang berhubungan dengan aspek lingkungan dan penghematan energi dalam sistem refrigersi dan tata udara, serta praktek penanganan sistem dengan refrigeran berbasis hidrokarbon. Dari hasil evaluasi kegiatan, diperoleh bahwa dengan pembekalan ini terjadi peningkatan pengetahuan, dan juga keterampilan peserta dalam menangani sistem AC Split serta hal penting yang harus diperhatikan dalam menangani refrigeran ramah lingkungan.

Obtaining and storing large amounts of data have become easier with the rapidly developing information technologies (IT). However, the data generated and collected, which are irrelevant in and of themselves, become useful only when they are analyzed for a specific reason. Data mining may transform raw data into useful information. In the present study, classification and analysis of denim fabric quality characteristics according to denim fabric production parameters were carried out. The present study proposes a new classification rule inference algorithm. The suggested approach is mostly based on Artificial Bee Colony Optimization (ABC), a swarm intelligence meta-heuristic. In each step of the algorithm, there are two phases called the employed bee phase and the onlooker bee phase. This algorithm has been compared with the classification algorithms in the related literature. This proposed algorithm is a new data mining tool that intelligently combines various metaheuristic and neural networks and can generate classification rules. The results indicate that the proposed data mining algorithms may be highly useful in determining weight and width in denim fabric manufacture.

Mortality risks of important diseases such as cancer can be estimated using gene profiles which are high-dimensional data obtained from gene expression sequences. However, it is impossible to analyze high-dimensional data with classical techniques due to multicollinearity, time-consuming processing load, and difficulty interpreting the results. For this purpose, extreme learning machine methods, which can solve regression and classification problems, have become one of the most preferred machine learning methods regarding fast data analysis and ease of application. The goal of this study is to compare estimation performance of risk score and short-term survival with survival extreme learning machine methods, L2-penalty Cox regression, and supervised principal components analysis in generated high-dimensional survival data. The survival models have been evaluated by Harrell’s concordance index, integrated Brier score, F1 score, kappa coefficient, the area under the curve, the area under precision-recall, accuracy, and Matthew’s correlation coefficient. Performances of risk score estimation and short-term survival prediction of the survival models for the censoring rates of 10%, 30%, 50% and 70% have been obtained in the range of 0.746-0.796, 0.739-0.798, 0.726-0.791, 0.708-0.784 for Harrell’s concordance index; 0.773-0.824, 0.772-0.824, 0.754-0.818, 0.739-0.808 for F1 score and 0.816-0.867, 0.808-0.865, 0.788-0.863, 0.776-0.851 for area under curve. All results showed that survival extreme learning machine methods that allow analyzing high-dimensional survival data without the necessity of dimension reduction perform very competitive with the other popular classical methods used in the study.
