Authors: Bodla M Afzal , Maria Afzal Bodla  , Syedah Nalain
Published: October 2024

Anemia-related retinopathy is a common condition, often asymptomatic and discovered incidentally during routine evaluations. A comprehensive, multidisciplinary approach is essential to ensure that even unusual presentations result in positive outcomes, preventing further morbidities and their long-term consequences. We present the case of a 22-year-old woman who reported a rapid decline in vision and sought care at Bodla Eye Care in Multan. She had only one functional eye (right), with the left eye affected by phthisis bulbi. Her best-corrected visual acuity in the right eye was limited to light perception.

Authors: Irawati Yunia , Casalita Vega , Dewi Nadia Kartika
Published: October 2024

We report a case of a 10-year-old patient presented with recurring nasolacrimal duct obstruction post-lacrimal sac cyst extirpation in which CT scan revealed a solidlesion that was more depicted by contrast-enhancedimage. The initial surgery and flap creation had inadvertently led to a mucosal shortage, posing a challenge for the subsequent procedure, which aimed to create aDacryocystorhinostomy (DCR). In a challenging approach, a buccal mucous membrane graft was employed to address the lack of mucous membrane required for the DCR. Over the course of five years, there was no recurrence of the cyst, signifying the success of this innovative treatment method of using buccal mucous membrane graft for external DCR.

Authors: Gull Ambreen
Published: October 2024

By 2030, cataract surgery is poised for a transformative overhaul, driven by advances in technology and a shift towards patient-centric care. This editorial explores the anticipated developments in cataract surgery, highlighting the role of precision, efficiency, and sustainability. Key innovations include the integration of Artificial Intelligence (AI) and Femtosecond laser technology, setting the stage for a revolutionary patient experience.
      The landscape of cataract surgery is set to change dramatically. Currently, cataract surgery is the most common ophthalmic procedure, with significant global and regional increases in the cataract surgical rate (CSR). Pakistan has almost doubled its CSR to 5307 in the last two decades.1Over four million cataract surgeries are performed annually in the United States. This number is increasing by 3-4% each year and is projected to reach six million by 2030.2
      Biometry, once a complex procedure, will be simplified through the use of swept-source OCT biometers equipped with the latest formulas. Modern IOL calculation formulae, like Barrett Universal II, Barrett True-K, Hill RBF, and Kane, are more precise than previous generations. The revolutionizing role of artificial intelligence (AI) and machine learning (ML) in optical biometry will ensure accurate measurements, further contributing to the overall success of the surgery.3

Defining the Quality Standards to Use and Cite PCR Primers and Probes from Literature
Authors: Bhatia Sdhir
Published: October 2024

Objective: Polymerase chain reaction (PCR) primers and probes from the medical literature are frequently used in current research and diagnostics, contributing to numerous publications. Our previous analysis revealed that many of these oligonucleotides fail to effectively detect all strains of various pathogens, leading to questionable results in published studies. Therefore, our goal is to establish quality standards for the use and citation of such primers and probes from the literature.
Materials and Methods: We analyzed approximately 500 publications from PubMed and other sources over the past 20 years. In many cases, in-silico analysis was performed, while in others, primers and probes were tested in laboratory settings.
Results: We identified numerous instances where outdated oligonucleotides from the literature are still being used, raising concerns about their ability to detect diverse pathogen strains. Authors utilizing these outdated primers and probes must provide evidence of their continued efficacy. Peer reviewers should also give this issue careful attention during the review process. In several cases, we redesigned and updated these oligos for use in our laboratory and in commercial kits.
Conclusion: We propose preliminary guidelines to address the use of outdated primers and probes, aiming to prevent questionable publications that result in the wastage of taxpayer funds. Addressing this issue is critical to producing high-quality results that can contribute to the development of new diagnostics, vaccines, and therapies.

Nuclear Policy and the Changing Dynamics of Decision-Making
Authors: Gottschalk Keith
Published: October 2024

Under the apartheid regime nuclear policy was decided by the president, with most of the cabinet being in the loop. The AfricanNational Congress (ANC) in exile sought to discover the facts, and to campaign against the apartheid regime acquiring nuclear weapon capabilities. Between 1991 and 1994, the ANC’s Science and Technology Policy group played a role in lobbying on nuclear policy issues, alongside some NGOs, culminating in the February 1994 conference on nuclear policy. After the came to power in April 1994, inaugurating democracy, the nuclear lobby within the bureaucracy and parastatals influenced the relevant ANC directors-general, cabinet ministers and one president. Statutory and regulatory agencies were compromised. Civil society organisations alonetook the lead in opposing nuclear energy, and were partly successful.

Представлены результаты анализа энергопотребления двух закрытых систем оборотного водоснабжения. Первый вариант – система с чиллером, установленным на улице с антифризом в качестве теплоносителя и сухой градирней, второй вариант – система с чиллером в теплом помещении и «зимним пуском». В качестве антифриза рассмотрен водный раствор пропиленгликоля. Расчеты проводились для фактических климатических условий Ленинградской области и одинаковых температурных режимах потребителей. Выполнен расчет энергопотребления на основании коэффициента преобразования (COP) обоих вариантов. COP рассчитан с учетом энергопотребления насосных станций (гидромодулей). На основании энергопотребления оборудования и стоимости электроэнергии сделаны выводы о целесообразности использования фрикулинга для рассматриваемой системы.

In the article we present the results of the analysis of energy consumption in two closed circulating water supply systems. The first option is a system with a chiller installed outdoors with antifreeze as a carrier and a dry cooling tower; the second option is a system with a chiller in a warm room and a "winter start". An aqueous solution of propylene glycol is considered as an antifreeze. Calculations were carried out for the actual climatic conditions of the Leningrad region and the same temperature conditions of consumers. We calculated the energy consumption based on the conversion coefficient (COP) of both variants. COP is calculated taking into account the energy consumption of pumping stations (hydraulic modules). Based on the energy consumption of the equipment and the cost of electricity, we drew some conclusions about the expediency of using freecooling for the system in question.

Services, Voronezh State Technical University, Voronezh, Russia, tel.: +7(473)207-22-20; e-mail: mzherlykina@cchgeu.ru The article presents the features of the design of energy supply facilities of housing and communal services. It has been revealed that external influence of natural and man-made origin can cause development of an emergency situation at an industrial facility. The article describes the origin and development of the shock wave and its consequences at industrial facilities. Attention is focused on the ventilation system as the object most affected by the shock wave. To ensure the safety of industrial facilities, we propose the installation of explosion-proof valves. We also demonstrate the boundary conditions for the operation of explosion-proof valves. Besides, we present the results of mathematical modeling of a linear polynomial equation of state. In the ANSYS LS-DYNA numerical simulation environment, a two-dimensional task is set, at the first stage of which the distance from the initiated charge is determined. We performed a numerical study on two scenarios, namely with and without the installation of an explosion-proof valve. We present the results of the study of dependence of pressure on time when approaching to the valve and we also show the results of the study of dependence of pressure on time on the sensors. As a result of numerical simulation of the loading of a ventilation universal explosion-proof valve by a shock wave, we have established the expediency of its application.

Authors: Половнева Д.О. , Василенко М.И.
Published: October 2024

В последнее время в качестве альтернативного решения для обработки воды бассейнов всё чаще предлагают экологически чистые и безопасные обеззараживающие препараты – полимерные ионогенные биоциды на основе синтетических высокомолекулярных полигуанидинов. К таким веществам относится полигексаметиленгуанидин гидрохлорид (ПГМГ-ГХ), который обладает широким спектром пролонгированного биоцидного действия в интервале температур воды 0…30 °С и рН 6…9. В работе приведены результаты исследований по выявлению альгицидных, фунгицидных, бактерицидных свойств биоцидного многофункционального средства (БМС) на основе производных гуанидина в интервале температур 20…45 °С с целью возможного его использования для воды открытых бассейнов, особенно в условиях южных стран. Экспериментально доказана высокая биоцидность концентрированного препарата по отношению к одноклеточным водорослям, вызывающим «цветение воды», энтеробактериям, часто обнаруживаемым в водах бассейнов, и микроскопическим грибам, заселяющим поверхности в условиях повышенных температур и влажности.

Environmentally friendly and safe disinfection solutions, namely polymer ionogenic biocides based on synthetic high-molecular polyguanidines, have recently been increasingly offered as an alternative solution for pool water treatment. Such substances include polyhexamethylene guanidine hydrochloride (PGMG-GC), which has a wide spectrum of prolonged biocidal action in the water temperature range of 0…30 °C and pH 6…9. The paper presents the results of studies on the identification of algicidal, fungicidal, bactericidal properties of a biocidal multifunctional agent (BMS) based on guanidine derivatives in the temperature range of 20…45 °C, taking into account its possible use for outdoor swimming pools, especially in southern countries. The high biocidicity of the concentrated solution has been experimentally proven in relation to unicellular algae that cause water blooming, enterobacteria, often found in pool waters, and microscopic fungi that inhabit surfaces at elevated temperatures and humidity.

Authors: Santos Pedro Anderson de Paiva dos , Giesta Luana Bortolini , Oliveira Fernando Pablo Silva , Pedrosa Virgínia Fonseca , Romano Luis Alberto
Published: October 2024

Aquaculture is a globally relevant sector in terms of production and income. When we think about  shrimp farming, Penaeus vannamei, the Pacific white shrimp, has been instrumental in this growth due to its characteristics and advances in production. Despite achievements, it faces significant economic challenges due to the white spot syndrome virus (WSSV), causing considerable losses. This virus has led to significant economic losses, affecting economies such as Ecuador's. The clinical signs of WSSV require rigorous diagnostic procedures, combining histopathological examination and PCR assays. A retrospective study of 900 specimens of Penaeus vannamei in Ecuador highlights the correlation between tissue pathology and mortality rates, enhancing understanding of the direct impact of the disease. Histopathological analysis reveals distinctive intracellular viral inclusions, reflecting disease progression. Although PCR assays provide definitive diagnoses, histopathological evaluation enriches understanding of lesion severity, supporting a comprehensive approach to disease management strategies.

La obstrucción de vía aérea superior (VAS) en pediátricos raramente puede requerir descartar entidades menos frecuentes como masas nasofaríngeas. Reporte de caso: Papiloma exofítico de difícil diagnóstico en paciente de 5 años y se discuten las características clínicas, imagenológicas y terapéuticas mediante revisión de la literatura. Discusión: La obstrucción grave de VAS en pediátricos requiere un estudio endoscópico e imagenológico completo. Los tumores de nasofaringe son causa poco frecuente de obstrucción de VAS en pacientes pediátricos. El papiloma exofítico es un tumor benigno de la cavidad nasal que se origina de la mucosa schneideriana, con alto potencial de recurrencia en resecciones subtotales. A la fecha hay pocos reportes de este tumor en pediátricos y nasofaringe. Conclusión: el papiloma nasosinusal es un tumor de baja incidencia en la edad pediátrica, pero debe ser considerado como causa infrecuente de obstrucción de VAS; brindar un abordaje diagnóstico es necesario para un tratamiento adecuado.

Background. Recurrent Pregnancy Loss (RPL) is a multifactorial disorder significantly impacting women’s health globally. Emerging research has implicated Neutrophil Extracellular Traps (NETs) in the pathophysi­ology of RPL, suggesting an immunological underpinning to miscarriage occurrences. Aim. The study aim to evaluate the role and expression of NETosis markers (MPO, histones H2A, H2B) in women with RPL in comparison to pregnant women. Methods. This prospective cohort study, conducted from January 2022 to July 2023, included 30 participants (20 RPL patients and 10 controls) from Al Basrah Maternity and Child Hospital. Immunohistochemical technique were employed to detect Myeloperoxidase and histones in placental samples. Statistical analysis was performed using SPSS, with significance set at p<90.05. Results. Immunohistochemical analysis of placental tissues indicated significant overexpression of Myelo­peroxidase (MPO), and histones H2A and H2B, in RPL patients compared to control, emphasizing the potential involvement of NETs in placental pathology associated with miscarriage. The expression levels of MPO were positive in 80% of RPL patients but undetected in control (p = 0.0001). Histone expressions also differed significantly, with H2A detected in 55% of RPL patients compared to none in control (p = 0.001) and H2B in 70% versus 30% (both p <0.001).
