Authors: Alsafi Firas Hameed Abd
Published: October 2024

The apolipoprotein E4 allele is a genetic risk factor that has a negative impact on the quality of life of people with cardiovascular disease. Our current study aimed to evaluate the effect of apolipoprotein E4 allele in cardiovascular patients (n=85). A total of 85 elderly patients with cardiovascular disease were enrolled in the study, which was conducted at hospitals in Baghdad, Iraq, between 18 January 2022 and 27 October 2023. Comprehensive cardiovascular examinations were performed on each patient, including blood pressure, heart rate, and other vital sign measurements. APOE genotype analysis was conducted to evaluate the impact on the patients. Additionally, questionnaires were administered to assess the quality of life of patients with cardiovascular disease. In terms of clinical outcomes, chest pain was identified as the most prevalent symptom among patients, with a total of 38 cases. Additionally, the E3/E4 genotype of the APOE gene was observed in 41.18% of patients, which was associated with an increase in serum lipid-lipoprotein levels in terms of SBP (145.39 ± 27.46) mmHg and DBP (87.89 ± The mean values for the variables were as follows: glucose (3.11 ± 1.12) mg/dL, triglycerides (224 ± 46.25) mg/dL, LDL-C (167.29 ± 12.92) mg/dL, and HDL-C (14.82 ± 3.82) mg/dL. The adverse findings revealed that 23 cases involved heart attacks, and 30 cases involved strokes. Patients with CVD who carried the apolipoprotein E4 allele exhibited negative impacts on their quality of life, as evidenced by the following scores: physical functioning (46.38 ± 14.26), energy/fatigue (53.25 ± 12.29), and emotional problems (62.10 ± 10.29). In general, patients with the apolipoprotein E4 allele exhibit elevated levels of lipid profiles, which signify an elevated risk of severe complications in patients with cardiovascular disease.

Abstract. Objectives. The objectives of this study were twofold: to analyze the composition and content of fatty acids in various adipose tissues (including kidney, abdominal, subcutaneous, and omental) of Yanbian yellow cattle and to observe the morphology of adipocytes within these tissues and to assess the level of expression of specific genes – kinase insert domain receptor (KDR), apolipoprotein L domain containing 1 (APOLD1), stearoyl-CoA desaturase 1 (SCD1), secreted frizzled-related protein 4 (SFRP4), fatty-acid-binding protein 5 (FABP5), and sterol carrier protein-2 (SCP2) – in different adipose tissues (kidney, abdominal, posterior belly, ribeye, prothorax, striploin, upper brain, and neck) of Yanbian yellow cattle.
Method. Castrated Yanbian yellow cattle, 24 months old, with identical genetic backgrounds and raised under the same breeding management conditions, were selected. The fatty acid composition and content were assessed using gas chromatography, while the size and diameter of adipocytes were analyzed via paraffin sectioning. The level of expression was determined using quantitative reverse transcription polymerase chain reaction (qRT-PCR). Results. In total, 16 distinct fatty acids were identified in abdominal adipose tissue. Additionally, henicosanoic acid (C21:0) and behenic acid (C22:0) were detected exclusively in subcutaneous adipose tissue. Caprylic acid (C8:0) was found in both kidney and omental adipose tissues. The size of individual adipocytes in kidney adipose tissue was notably larger compared to the adipocytes in the other three regions (p<0.05). Regarding gene expression, APOLD1 exhibits its highest expression in striploin adipose tissues (p<0.05), while SCD1 shows its peak expression in prothorax adipose tissues (p<0.05). Moreover, both FABP5 and SCP2 demonstrate their highest level of expression in prothorax adipose tissue (p<0.05). Furthermore, the level of expression of KDR and SFRP4 across these seven adipose tissue regions exhibits significant differences (p<0.05). Conclusion. In conclusion, Yanbian yellow cattle exhibit variations in both the composition and content of fatty acids across different adipose tissue depots, including the kidney, abdominal, subcutaneous, and omental regions. Moreover, adipocytes display distinct morphological differences across these tissue types. Furthermore, the level of expression of KDR, APOLD1, SCD1, SFRP4, FABP5, and SCP2 varies significantly among adipose tissues located in the kidney, abdominal, posterior belly, ribeye, prothorax, striploin, upper brain, and neck regions.

Abstract. Bitter vetch and sorghum grains are alternative local feed resources that are underutilized in the southern Mediterranean area. This study aimed to assess the effects of incorporating these grains into the diet of local goat breeds on growth performance, carcass characteristics, and meat quality. Twenty-four goat kids were divided into three groups. The control group received a conventional diet consisting of oat hay, barley, and fava beans. In the first group, fava beans were replaced with bitter vetch, and in the second group, barley was replaced with sorghum. At the end of the trial, the animals were slaughtered and carcass characteristics and meat fatty acid profiles of the longissimus dorsi (LD) muscle were determined. Alternative grain incorporation had no significant effect on the growth parameters. Still, it significantly affected carcass characteristics, especially in the sorghum group compared to the control group, where mesenteric fat was lower (266 vs. 437 g). The back color was lighter (L*=55.1 vs. 59.1) and less yellow (a*=-1.29 vs. 2.22). The diet also influenced the meat's chemical composition, with less protein and ash in the chevrons of animals receiving bitter vetch and sorghum grains, respectively. Regarding the fatty acid (FA) profile, sorghum grains had decreased C18:2 n-6 and polyunsaturated FA (PUFA), whereas bitter vetch grains had increased C18:3 n-3, elongase activity, and nutritive value index (NVI). The control group exhibited intermediate results for C15:0, C16:0, C16:1, C20:3 n-3, n-3, health promoting index (HPI), and thrombogenic index (TI). No significant effects were reported for saturated FA (SFA) and monounsaturated FA (MUFA). Bitter vetch and sorghum grains can be safely incorporated into fattening diets of goat kids.
Air mass history linked to the development of Arctic mixed-phase clouds
Authors: Murray-Watson Rebecca J. , Gryspeerdt Edward
Published: October 2024

Abstract. Clouds formed during marine cold-air outbreaks (MCAOs) exhibit a distinct transition from stratocumulus decks near the ice edge to broken cumuliform fields further downwind. The mechanisms associated with ice formation are believed to be crucial in driving this transition, yet the factors influencing such formation remain unclear. Through Lagrangian trajectories collocated with satellite data, this study investigates the development of mixed-phase clouds using these outbreaks. Cloud formed in MCAOs are characterized by a swift shift from liquid to ice-containing states, contrasting with non-MCAO clouds also moving off the ice edge. These mixed-phase clouds are predominantly observed at temperatures below −20 °C near the ice edge. However, further into the outbreak, they become dominant at temperatures as high as −13 °C. This shift is consistent with the influence of biological ice-nucleating particles (INPs), which become more prevalent as the air mass ages over the ocean. The evolution of these clouds is closely linked to the history of the air mass, especially the length of time it spends over snow- and ice-covered surfaces – terrains may that be deficient in INPs. This connection also accounts for the observed seasonal variations in the development of Arctic clouds, both within and outside of MCAO events. The findings highlight the importance of understanding both local marine aerosol sources near the ice edge and the overarching INP distribution in the Arctic for modelling of cloud phase in the region.
Dominant influence of biomass combustion and cross-border transport on nitrogen-containing organic compound levels in the southeastern Tibetan Plateau

Published: October 2024

Abstract. The Tibetan Plateau (TP) is highly susceptible to climate change, and nitrogen-containing organic compounds (NOCs) in fine particulate matter (PM2.5) represent one of the largest uncertainties with respect to their impact on the climate in high-altitude areas. Previous studies have shown that NOCs play a vital role in the nitrogen budget of PM2.5. However, our understanding of the composition and sources of NOCs in PM2.5, particularly in the TP, is limited. Here, we aim to enhance our understanding of NOCs in the TP region by examining their identification, concentration levels, sources, and origins. We conducted field sampling at a regional background sampling site in Gaomeigu, in the southeastern margin of the TP from 11 March to 13 May 2017, followed by laboratory analysis of the NOCs collected on the filters. The daily mass concentrations of NOCs ranged from 714.4 to 3887.1 ng m−3, with an average of 2119.4 ± 875.0 ng m−3 during the campaign. This average concentration was approximately 40 % higher than that reported at a typical regional site in the North China Plain (NCP), highlighting a more significant presence of NOCs in the Tibetan area. Biomass burning and secondary sources were identified as the major contributors to total NOCs. This was further substantiated by a regional air quality model, which indicated that over 80 % of the aerosol in the southeast of the TP originated from neighboring countries. This study improves our understanding of NOCs' contribution to PM2.5 in the TP and their potential impacts on climate stability in high-altitude areas.

Abstract. In this study, we demonstrate the utility of available correlative measurements of carbon species to identify regional and local air mass characteristics as well as their associated source types. In particular, we combine different regression techniques and enhancement ratio algorithms with carbon monoxide (CO), carbon dioxide (CO2), and methane (CH4) total column abundance from 11 sites of the Total Carbon Column Observing Network (TCCON) to infer relative contributions of regional and local sources to each of these sites. The enhancement ratios provide a viable alternative to univariate measures of relationships between the trace gases that are insufficient in capturing source-type and transport signatures. Regional enhancements are estimated from the difference between bivariate regressions across a specific time window of observed total abundance of these species (BERr for bulk enhancement regression ratio) and inferred anomalies (AERr for anomaly enhancement regression ratio) associated with a site-specific background. Since BERr and AERr represent the bulk and local species enhancement ratio, respectively, its difference simply represents the site-specific regional component of these ratios. We can then compare these enhancements for CO2 and CH4 with CO to differentiate between combustion and non-combustion air masses. Our results show that while the regional and local influences in enhancements vary across sites, dominant characteristics are found to be consistent with previous studies over these sites and with bottom-up anthropogenic and fire emission inventories. The site in Pasadena shows a dominant local influence (> 60 %) across all species enhancement ratios, which appear to come from a mixture of biospheric and combustion activities. In contrast, Anmyeondo shows more regionally influenced (> 60 %) air masses associated with high-temperature and/or biofuel combustion activities. Ascension Island appears to only show a large regional influence (> 80 %) on CO / CO2 and CO / CH4, which is indicative of transported and combustion-related CO from the nearby African region, consistent with a sharp rise in column CO (3.51 ± 0.43 % ppb yr−1) at this site. These methods have important applications to source analysis using spaceborne column retrievals of these species.
The weather of 1740, the coldest year in central Europe in 600 years
Authors: Brönnimann Stefan , Filipiak Janusz , Chen Siyu , Pfister Lucas
Published: October 2024

Abstract. The winter of 1739/40 is known as one of the coldest winters in Europe since early instrumental measurements began. Many contemporary sources discuss the cold waves and compare the winter to that of 1708/09. It is less well known that the year 1740 remained cold until August and was again cold in October and that negative temperature anomalies were also found over Eurasia and North America. The 1739/40 cold season over northern mid-latitude land areas was perhaps the coldest in 300 years, and 1740 was the coldest year in central Europe in 600 years. New monthly global climate reconstructions allow us to address this momentous event in greater detail, while daily observations and weather reconstructions give insight into the synoptic situations. Over Europe, we find that the event was initiated by a strong Scandinavian blocking in early January, allowing the advection of continental cold air. From February until June, high pressure dominated over Ireland, arguably associated with frequent eastern Atlantic blocking. This led to cold-air advection from the cold northern North Atlantic. During the summer, cyclonic weather dominated over central Europe, associated with cold and wet air from the Atlantic. The possible role of oceanic influences (El Niño) and external forcings (eruption of Mount Tarumae in 1739) are discussed. While a possible El Niño event might have contributed to the winter cold spells, the eastern Atlantic blocking is arguably unrelated to either El Niño or the volcanic eruption. All in all, the cold year of 1740 marks one of the strongest, arguably unforced excursions in European temperature.

Published: October 2024

Abstract. We present a methodological study to document the operation of a new submodel for tracer emissions from Explosive Volcanic ERuptions (EVER v1.1), developed within the Modular Earth Submodel System (MESSy, version 2.55.1). EVER calculates additional tendencies of gaseous and aerosol tracers based on volcanic emission source parameters, aligned to specific sequences of volcanic eruptions. It allows for the mapping of size-resolved volcanic ash to number and mass of different size modes, and the employment of various vertical emission profiles. The new submodel is evaluated in atmospheric simulations with the ECHAM/MESSy Atmospheric Model (EMAC) coupling the general circulation model ECHAM5 to EVER and other MESSy submodels, using satellite observations of SO2 column amounts and mixing ratios as well as aerosol optical properties following the explosive eruption of the Nabro volcano (Eritrea) in 2011. Sensitivity studies explore perturbations of the emission source parameters, such as plume location, emitted mass, plume altitude, vertical distribution, and timing of the emission. We integrate information from a volcanic SO2 emission inventory, additional satellite observations, and our findings from the sensitivity studies to establish a historical standard setup for volcanic eruptions impacting stratospheric SO2 from 1990 to 2023. We advocate for this to be a standardized setup in all simulations within the MESSy framework concentrating on the upper troposphere and stratosphere in this period. Additionally, we demonstrate the applicability of the new submodel for the simulation of degassing volcanoes, with further potential applications in studies on volcanic ash, wildfires, solar geoengineering, and atmospheric transport processes.
Snow Particle Motion in Process of Cornice Formation
Authors: Yu Hongxiang , Lehning Michael , Li Guang , Walter Benjamin , Huang Jianping , Huang Ning
Published: October 2024

Abstract. Snow cornices are a common snow pattern in cold regions, and their fracture and collapse can easily trigger avalanches. Despite numerous observations and experimental simulations on their formation process, the microscopic mechanism of their formation remains unclear. In this paper, based on wind-tunnel experiments and high-speed photography, experimental studies on the trajectory of particles surrounding the snow cornice were carried out. Results indicated that the cornice is composed of small-sized snow particles. Saltation is the most dominant moving pattern for particles adhering to cornice. Notably, particles at the edge exhibit lower impact velocities and a wider distribution of impact angles compared to those on the surface. Further analysis of force balance equations of particles at the edge explains the shape-forming mechanism of wedged-like snow cornice. This work enhances the understanding of the micro-mechanism of snow cornice formation, offering theoretical insights for avalanche prediction.
Vapor pressure deficit plays a pivotal role in the carbon dioxide sink of the Jingxin Wetland
Authors: Zhang Jihao , Chen Pengshen , Liu Duqi , Liang Ruihan , Cui Guishan
Published: October 2024

Abstract. Large uncertainties exist in the carbon sink and energy balance of wetland ecosystems under climate change conditions. This can be attributed, in part, to the limited understanding of the simultaneous impact of climate and carbon dynamics as well as that of energy equilibria. In addition, the temporal patterns and interconnections of carbon dynamics and energy equilibria, as inferred from ground observations, remain ambiguous. In this study, carbon dioxide flux data of the Jingxin Wetland from August 2021 to August 2023 were analyzed to evaluate the relative influence of climate change on the net ecosystem exchange (NEE) and energy equilibrium. The findings demonstrate that the Jingxin Wetland has a formidable capacity for carbon sequestration. Furthermore, the vapor pressure deficit (VPD) emerged as a key determinant of ecosystem carbon flux, whereas latent heat flux (LE) serves as the primary consumer of net radiation. Throughout the research period, net radiation (Rn) accounted for 73.5 % of the total radiation. During both vegetation growth and dormancy seasons, Rn emerged as a principal factor influencing LE, which in turn affected the state of carbon cycling in the wetland ecosystems by impacting variations in the VPD during the growing season. Overall, our research outcomes shed light on the interplay between climate, carbon cycles, and energy budgets in wetland ecosystems, offering valuable insights for future investigations and conservation endeavors.
Operationalizing fine-scale soil property mapping with spectroscopy and spatial machine learning

Published: October 2024

Abstract. One challenge in soil mapping is the transfer of new techniques and methods into operational practice, integrating them with traditional field surveys, reducing costs, and increasing the quality of the soil maps. The latter is paramount, as they form the basis for many thematic maps. As part of a novel approach to soil mapping, we integrate various technologies and pedometric methodologies to create soil property maps for soil surveyors, which they can utilize as a reference before beginning their pedological fieldwork. This gives the surveyors considerably more detailed and accurate prior information, reducing the subjectivity inherent in soil mapping. Our approach comprises a novel soil sampling design that effectively captures spatial and feature spaces, mid-infrared spectroscopy, and spatial machine learning based on a comprehensive set of covariates generated through various feature engineering approaches. We employ multi-scale terrain attributes, temporal multi-scale remote sensing, and Euclidean distance fields to account for environmental correlation, spatial non-stationarity, and spatial autocorrelation in machine learning. Methods to reduce the uncertainties inherent to the spectral and spatial data were integrated. The new sampling design is based on a geographical stratification and focuses on the local soil variability. The method identifies spatially local minima and maxima of the feature space, which is fundamental to soil surveys at the specified scale. The k-means and Kennard-Stone algorithms were applied in a sequential manner within each cell of a hexagonal grid overlaying the study area. This approach permits a systematic sub-sampling from each cell to analyze predictive accuracy for varying sampling densities. We tested one to three samples per hectare. Our findings indicate that a sample size of two samples per hectare was sufficient for accurately mapping soil properties across 300 hectares. This markedly reduces the financial burden associated with subsequent projects, given the significant reduction in the time and resources required for surveying. The spectroscopic and spatial models were unbiased and yielded average R2 values of 0.91 and 0.68–0.86, depending on mapping with or without pedotransfer models. Our study highlights the value of integrating robust pedometric technologies in soil surveys.
Sensitivity of hydrological machine learning prediction accuracy to information quantity and quality
Authors: Jeung Minhyuk , Her Younggu , Baek Sang-Soo , Yoon Kwangsik
Published: October 2024

Abstract. Machine learning (ML) is now commonly employed as a tool for hydrological prediction due to recent advances in computing resources and increases in data volume. The prediction accuracy of ML (or data-driven) modeling is known to be improved through training with additional data; however, the improvement mechanism needs to be better understood and documented. This study explores the connection between the amount of information contained in the data used to train an ML model and the model’s prediction accuracy. The amount of information was quantified using Shannon’s information theory, including marginal and transfer entropy. Three ML models were trained to predict the flow discharge, sediment, total nitrogen, and total phosphorus loads of four watersheds. The amount of information contained in the training data was increased by sequentially adding weather data and the simulation outputs of uncalibrated and/or calibrated mechanistic (or theory-driven) models. The reliability of training data was considered a surrogate of information quality, and accuracy statistics were used to measure the quality (or reliability) of the uncalibrated and calibrated theory-driven modeling outputs to be provided as training data for ML modeling. The results demonstrated that the prediction accuracy of hydrological ML modeling depends on the quality and quantity of information contained in the training data. The use of all types of training data provided the best hydrological ML prediction accuracy. ML models trained only with weather data and calibrated theory-driven modeling outputs could most efficiently improve accuracy in terms of information use. This study thus illustrates how a theory-driven approach can help improve the accuracy of data-driven modeling by providing quality information about a system of interest.
Co- and postseismic subaquatic evidence for prehistoric fault activity near Coyhaique, Aysén Region, Chile

Published: October 2024

Abstract. Chilean Patagonia is confronted with several geohazards due to its tectonic setting, i.e., the presence of a subduction zone and numerous fault zones, e.g., the Liquiñe-Ofqui Fault Zone (LOFZ). This region has therefore been the subject of numerous paleoseismological studies. However, this study reveals that the seismic hazard is not limited to these large tectonic structures by identifying past fault activity near Coyhaique in Aysén Region. Mass-wasting deposits in Lago Pollux, a lake located ca. 15 km SW of this region's capital, were identified through analysis of reflection-seismic data and were linked to a simultaneous event recorded in nearby Lago Castor. Furthermore, a coeval ∼50-year-long catchment response was identified in Aysén Fjord based on the multiproxy analysis of a portion of a sediment core. Assuming that this widely recognized event was triggered by an earthquake, ground-motion modeling was applied to derive the most likely magnitude and source fault. The model showed that an earthquake rupture along a local fault, in the vicinity of Lago Pollux and Lago Castor, with a magnitude of 5.6–6.8, is the most likely scenario.
A description of Model Intercomparison Processes and Techniques for Ocean Forecasting
Authors: Hernandez Fabrice , Garcia Sotillo Marcos , Melet Angelique
Published: October 2024

Abstract. The availability of numerical simulations for ocean past estimates or future forecast worldwide at multiple scales is opening new challenges in assessing their realism and predictive capacity through an intercomparison exercise. This requires a huge effort in designing and implementing a proper assessment of models’ performances, as already demonstrated by the atmospheric community that was pioneering in that sense. Historically, the ocean community launched only in the recent period dedicated actions aimed at identifying robust patterns in eddy-permitting simulations: it required definition of modelling configurations, execution of dedicated experiments that deal also with the storing of the outputs and the implementation of evaluation frameworks. Starting from this baseline, numerous initiatives like CLIVAR for climate research and GODAE for operational systems have raised and are actively promoting best practices through specific intercomparison tasks, aimed at demonstrating the efficient use of the Global Ocean Observing System and the operational capabilities, sharing expertise and increase the scientific quality of the numerical systems. Examples, like the ORA-IP, or the Class 4 near real time GODAE intercomparison are introduced and commented, discussing also on the ways forward on making this kind of analysis more systematic for addressing monitoring of ocean state in operations.
Probabilistic surrogate modeling of damage equivalent loads on onshore and offshore wind turbines using mixture density networks
Authors: Singh Deepali , Dwight Richard , Viré Axelle
Published: October 2024

Abstract. The use of load surrogates in offshore wind turbine site assessment has gained attention as a way to speed up the lengthy and costly siting process. We propose a novel probabilistic approach using mixture density networks to map 10 min average site conditions to the corresponding load statistics. The probabilistic framework allows for the modeling of the uncertainty in the loads as a response to the stochastic inflow conditions. We train the data-driven model on the OpenFAST simulations of the IEA 10 MW reference wind turbine (IEA-10MW-RWT) and compare the predictions to the widely used Gaussian process regression. We show that mixture density networks can recover the accurate mean response in all load channels with values for the coefficient of determination (R2) greater than 0.95 on the test dataset. Mixture density networks completely outperform Gaussian process regression in predicting the quantiles, showing an excellent agreement with the reference. We compare onshore and offshore sites for training to conclude the need for a more extensive training dataset in offshore cases due to the larger feature space and more noise in the data.

There were examined 282 patients, men n=138(49%), women n=144(51%) with liver pathology, whom were divided into groups: 1 gr - with chronic hepatitis n=75 (27. 4%), 2 gr - with chronic fatty non-alcoholic liver disease n=96 (34. 2%), and 3 gr - with liver cirrhosis of various etiology n=111 (39. 4%). The average age is 54. 23. Anthropometric studies were carried out (chest circumference, waist circumference, circumference of the middle part of the shoulder, thigh circumference), body mass index was calculated. In all patients, we studied the indicators of protein metabolism - total protein and albumin levels in blood serum. Results. The study revealed the presenceof abdominal fat in all patients, characteristic of obesity sarcopenia and a decrease in protein metabolism: total protein and albumin in patients with liver cirrhosis. Conclusions. All patients have an android type of adipose tissue distribution and are at high risk of developing comorbid cardiovascular and endocrine dysfunction.

В июне 2024 года в ходе энтомологического мониторинга обнаружены новые местообитания опасного инвазивного вида – азиатского тигрового комара Aedes (Stegomyia) albopictus (Skuse, 1895) на Крымском полуострове. Повторные находки вида в г. Симферополе могут свидетельствовать о формировании стабильно воспроизводящихся городских популяций. Впервые отмечено присутствие Ae. albopictus в естественных биоценозах на территории Карадагского природного заповедника. Высокая экологическая пластичность вида позволяет предположить возможность успешного формирования сети локальных синантропных популяций в населенных пунктах степной зоны, что значительно увеличит их опасность как переносчиков циркулирующих среди людей заболеваний.

Рассмотрена многолетняя (1994–2023 гг.) динамика численности и экология размножения деревенской ласточки (Hirundo rustica L.) и воронка (Delichon urbica (L.)) на территории Усманского бора. Оценено влияние различных факторов на динамику численности ласточек. Наиболее существенным, определяющим количество ежегодно гнездящихся пар ласточек, фактором является наличие и доступность объектов питания (летающих насекомых) в период размножения.
O Uso Racional dos Almoxarifados na Administração Pública: Um Estudo de Caso no IFPI – Campus Paulistana
Authors: Rocha Leonardo Victor da Luz , Lopes Veronica Maria Neto
Published: October 2024

As organizações públicas enfrentam um constante desafio na administração de almoxarifados e estoques, com recursos limitados e locais muitas vezes inadequados que são transformados em estoques. A busca pela eficiência fica comprometida e a não racionalização do espaço físico pode causar o acúmulo de materiais. Além de ocasionar atrasos ou paralisações de setores por falta de materiais ou gastos desnecessários com materiais que ficam parados no almoxarifado. O presente estudo foi realizado no setor de almoxarifados e patrimônio e nos depósitos do Instituto Federal de Educação, Ciência e Tecnologia (IFPI) Campus Paulistana. O objetivo geral foi observar o gerenciamento de estoques quanto ao uso do espaço físico, e a partir dos dados coletados e pontos críticos detectados propor ações de adequação aos processos de gerenciamento de estoque nos setores estudados. A metodologia utilizada foi um estudo de caso realizado por entrevistas com os responsáveis pelos setores, observação livre desses locais e solicitação de preenchimento de planilhas com os itens armazenados após as coletas, discussões e análises dos dados, foi feita uma proposta de classificação xyz a partir da análise apresentada por Fenili (2016). Ela seguiu-se de sugestões de melhorias na reorganização, localização e descarte de materiais a curto e longo prazo. A intervenção no almoxarifado consistiu na organização dos materiais por tipo e finalidade de uso, foram priorizados os itens com proximidade ao vencimento, e os produtos mais utilizados foram posicionados mais próximos da entrada. Também foram mantidos corredores livres, permitindo uma melhor circulação de pessoas. Essas ações visam otimizar a gestão do espaço e melhorar a eficiência operacional.

Published: October 2024

Objetivo: A pandemia do HIV é um problema de saúde mundial; há ao menos 38 milhões de indivíduos infectados. O HIV possui como alvo os linfócitos T CD4+, prejudicando a função e causando a redução do número dessas células. A imunodeficiência adquirida resulta em um aumento da suscetibilidade a várias infecções, entre elas, o Histoplasma capsulatum. Em pacientes com contagem de linfócitos CD4+ < 50 células/mm3, sem tratamento rápido e adequado, essa micose pode ser fatal. O objetivo deste trabalho é descrever um caso de histoplasmose em paciente HIV positivo e ressaltar a importância do diagnóstico e do tratamento. Método: Paciente M. D. S, 27 anos, sexo masculino, HIV+, virgem de tratamento, procurou o serviço de saúde relatando náuseas, vômitos, febre, mialgia, dores abdominais, tosse e astenia. Foi tratado para úlcera péptica, porém, retorna à unidade de atendimento com piora do estado geral. Realizou tomografia computadorizada (TC) de tórax, compatível com quadro de pneumocistose e pneumonia bacteriana associada, sendo necessário o encaminhamento para unidade de tratamento intensivo de um hospital terciário. Conclusão: O paciente apresentou hemocultura positiva para S. aureus oxa-S e S. lugdunensis oxa-S; no hemograma, foram observados anemia (Hb 6,5 g/dl), leucocitose (54,36 mil/mm3), neutrofilia (89,4%) e presença de frequentes formas intra e extracelulares sugestivas de Histoplasma sp. O mielograma observou figuras de hemofagocitose e presença de parasitas intracelulares, RT-PCR EBV e CMV positivo. Após cinco dias de internação, evoluiu com queda do estado geral, indo a óbito. Não há cura para o HIV, porém, há distribuição dos medicamentos antirretrovirais pelo Sistema Único de Saúde (SUS), que são eficazes para o controle da replicação viral, mantendo a capacidade de resposta imunológica frente a infecções, diminuindo a mortalidade e proporcionando uma melhor qualidade de vida ao indivíduo infectado. Apesar de possuir uma terapia de controle eficiente, o diagnóstico permanece carregado de desinformação, preconceito e segregação social. Referências: 1. Coinfecção histoplasmose e Aids.

Published: October 2024

Objetivo: As mucopolissacaridoses (MPS) são um grupo de doenças genéticas raras marcadas por erros inatos do metabolismo que causam deficiência das enzimas lisossômicas que degradam os glicosaminoglicanos, o que ocasiona o acúmulo anormal destes no interior de diferentes tecidos e órgãos, comprometendo a função celular e orgânica e desencadeando um quadro clínico multissistêmico. A depender do tipo de deficiência enzimática, as MPS podem ser classificadas em 11 tipos, cada uma com sintomas e gravidade diferentes(1-3). Esse relato de caso teve como objetivo evidenciar a importância do diagnóstico laboratorial nas MPS e salientar a análise do hemograma como uma ferramenta relevante no rastreamento dessa doença. Método: Recém-nascido S. L. S. G., sexo masculino, com diagnóstico antenatal de hidropsia fetal de causa a esclarecer. Ao nascimento, necessitou de manobras de reanimação e intubação orotraqueal. Foram realizados exames de imagem para investigação. A ultrassonografia (US) evidenciou derrame pleural, ascite e hemorragia intracraniana grau I. Foram solicitados exames laboratoriais complementares. Conclusão: Foram detectadas hiponatremia e hipocalemia. No hemograma, verificou-se anemia (Hb 4,92 g/dl), plaquetopenia (8 mil/mm³) e leucopenia (3,92 mil/ mm3), com presença de intensas granulações azurófilas nos leucócitos sugestivas de MPS. A critério médico, sugeriram-se correlação diagnóstica e investigação complementar. A criança evoluiu com colestase, IRA dialítica e distúrbios de coagulação. Foram realizadas transfusões de hemocomponentes. No 21º dia de vida, constatou-se o óbito decorrente de parada cardiorrespiratória. Em acompanhamento genético, foi diagnosticada a MPS tipo VII (síndrome de Sly). A morfologia inicial observada no hemograma foi crucial para a suspeita clínica, bem como para o seguimento dos exames complementares e posterior diagnóstico. Referências: 1.

Objetivo: Os dímeros D (DD) são produtos específicos da degradação de coágulos de fibrina, dos marcadores de trombose e da fibrinólise e suas dosagens contribuem para excluir eventos tromboembólicos. Este estudo tem como objetivo apresentar os resultados de um ensaio de proficiência (EP) para DD, conduzido entre novembro de 2015 e julho de 2022. Método: O EP foi realizado com quatro rodadas/ano (três amostras liofilizadas de plasma/rodada). Os dados analisados foram: número de participantes, métodos, média do coeficiente de variação (CV) e porcentagem de resultados corretos (RC) por método. Conclusão: A amostra foi composta por 614 participantes, (602 brasileiros e 12 de outros países), com 22.200 dados. Os métodos foram: ensaio de fluorescência ligado a enzima (ELFA) (n = 117), imunoensaio de fluorescência (FIA) (n = 162), imunoturbidimetria (IT) (n = 446) e quimioluminescência (Q) (n = 12). ELFA, IT e Q são métodos automatizados, e FIA é teste de point-of-care (POCT). ELFA apresentou 7,6% de CV e 96% de RC; FIA, 19,4% de CV e 90% de RC; IT, 8,8% de CV e 94% de RC; e Q, 10,3% de CV e 75% de RC (p < 0,05 para todas as comparações). Os resultados do EP mostraram uma boa comparabilidade entre os métodos. ELFA apresentou o melhor desempenho em termos de precisão e exatidão e FIA, o maior CV. No entanto, FIA apresentou uma maior porcentagem de RC se comparado com Q (o menor desempenho de Q pode ser devido ao pequeno número de participantes). Compreender e monitorar a imprecisão (erro aleatório) e a inexatidão (erro sistemático) do processo analítico é essencial para atingir a qualidade desejada na rotina laboratorial.
