Published: February 2024

Background/Aims: Polycythemia vera (PV) and essential thrombocythemia (ET) are chronic myeloproliferative diseases. Along with the increase in myeloproliferative cell lines, they can cause various clinical outcomes such as arterial and venous thrombosis, pulmonary hypertension, and myocardial infarction. This study was designed to evaluate the cardiac effects of these diseases via electrocardiography and echocardiography.
Methods: A total of 50 patients with a diagnosis of PV, 50 patients with a diagnosis of ET, and 50 healthy individuals as a control group were included in this study. Data on patient demographics were recorded in all subjects. All patients and control subjects had electrocardiography (ECG) recordings and routine transthoracic echocardiographic examination. Pulse wave velocity (PWV) was assessed with a Holter blood pressure device.
Results: In total, 50 PV patients, 50 ET patients, and 50 control group were included in the study. The demographic characteristics of the PV, ET and control groups were similar. The PR interval was significantly shorter in control subjects than in PV and ET patients (p:0.007, p:0.024). Although the measured values were within normal limits, diastolic posterior wall thickness was significantly lower in the control group compared to PV and ET patients (p:0.019, p:0.009). PWV was significantly higher in ET patients compared to the control group (p:0.012).
Conclusion: In this study, evaluating the effects of PV and ET on electrocardiography and transthoracic echocardiography; ECG parameters used to predict ventricular arrhythmias (QT, QTc, Tp-Te, Tp-Te/QT) and Pulmonary Artery Pressure showed no significant change, in opposition to existing literature. Nonetheless, similar to previous publications, PV and ET were found to negatively affect the diastolic function parameters on transthoracic echocardiography. While the aortic stiffness was significantly higher in ET patients compared to the control group, no significant difference was noted between PV patients and control subjects in terms of aortic stiffness.

Published: February 2024

Aim: This study aimed to delineate the single-center experience surrounding the long-term consequences of surgical reconstruction in subjects with late-presenting DDH (developmental dysplasia of the hip).
Methods: We analyzed 23 hips of 21 subjects aged >6 years who underwent surgical interventions, such as pelvic osteotomy, open reduction, femoral shortening, and derotation, for developmental hip dysplasia.
Results: After a median follow-up of 23.34 (8–120) months, there were no noteworthy alterations in the Harris score and anteversion. Nevertheless, significant improvements were observed in SHARP, CE angle, and depth and width index over the follow-up duration. Using Sever’s radiological criteria, 87.1% of subjects achieved excellent and good results. Assessment of femoral head avascular necrosis, based on Bucholz and Ogden’s classification, produced the subsequent findings: 52% of hips were Type I; 13% were Type II; 22% were Type III; and 13% were categorized as Type IV.
Conclusion: Despite achieving favorable postoperative radiological outcomes, there's a noticeable decline in clinical success in these subjects, especially as their age increases. Additionally, they face an elevated risk of avascular necrosis. The juxtaposition of a 75% radiological success rate with a 50% clinical success rate accentuates this contrast. Crucially, the success rate of surgical corrections in late-presenting DDH is tied to the age of the patient, with the success rate decreasing as age progresses.

Authors: DEMİRCİOĞLU Sinan , CİFTCİLER Rafiye , TEKİNALP Atakan , KARS Taha Ulutan
Published: February 2024

Background:Since the development of tyrosine kinase inhibitors (TKIs), the prognosis for chronic myeloid leukemia (CML) has significantly improved. Several predicted prognostic scores and indicators at diagnosis have been used to predict the prognosis of chronic phase chronic myeloid leukemia (CML-CP) during the TKI period. When CML patients are first diagnosed, hemogram parameter aberrations are rather prevalent in clinical practice, although it is still unknown how those parameters affect the prognosis. This study aims to evaluate the hemogram parameters at diagnosis on the survival outcomes of CML-CP patients.
Materials and Methods:One hundred thirty-seven patients who were diagnosed with CML-CP and received treatment were assessed between the years 2006 and 2020.
Results:There were 65 (47.4%) males and 72 (52.6%) females with a median age of 50 (range: 18-78) years at diagnosis. Median hemoglobin level was 12.1 gr/dL (4.3-17.4), leucocyte count was 66.2 ×109 /L (7.5-520.2), and thrombocyte count was 362 ×109 /L (18-3.496) for all patients. The median progression-free survival (PFS) was 16.7 months 16.7 (2.0-106.4) and the median overall survival (OS) was 63.8 months (0.43-166.2) for all patients.
Conclusion:This study is valuable in terms of predicting the prognosis of CML patients with hemoglobin, leukocyte, and platelet values at the time of diagnosis. While emphasizing the importance of platelet count at the time of diagnosis, similar to the previously defined risk scores, it showed that leukocyte and hemoglobin values at the time of diagnosis did not have a statistically significant effect on OS and PFS.

Authors: KIRIŞKA Muhammed Salih , BELVİRANLI Muaz , OKUDAN Nilsel
Published: February 2024

Background/Aims: This study aimed to investigate the cytokine response to acute endurance exercise performed in the LBPPT and to compare it with the regular treadmill.
METHODS: Eleven healthy physically active men aged between 18-22 years participated in the study. All subjects performed 45 minutes of running exercise at 70% VO2max on the regular treadmill and LBPPT in random order, one week apart. Blood samples were collected at pre-exercise, immediately post-exercise, 30 min post-exercise, and 2 h post-exercise to analyze serum high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α), and interleukin-8 (IL-8) levels.
RESULTS: On the regular treadmill, hs-CRP levels were higher immediately, 30 min, and 2 h post-exercise than pre-exercise. In addition, it was lower 2 h post-exercise compared with immediately, and 30 min post-exercise. No significant differences in LBPPT for hs-CRP were observed for any time point. hs-CRP concentration immediately and 30 min post-exercise was lower in the LBPPT than in the regular treadmill. TNF-α and IL-8 levels were unchanged in response to exercise performed neither on the regular treadmill nor on the LBPPT.
CONCLUSIONS: Acute endurance exercise may not be sufficient to induce a significant systemic inflammatory response in physically active men.

Published: February 2024

A doença de Zuska (DZ) ou metaplasia escamosa dos ductos lactíferos (SMOLD) é um processo inflamatório na porção central da mama, devido à oclusão de um ducto anormal, através da descamação epitelial. Os principais fatores de risco são tabagismo (90%) (1), obesidade, trauma, diabetes mellitus (DM), procedimentos iatrogênicos e imunossupressão (2). Apresentamos uma paciente de 56 anos, com quadro clínico de fístula cutânea na mama esquerda, com ressecção dos ductos principais e laudo histopatológico de DZ. Nosso caso retrata uma paciente não tabagista, o que configura um caso raro, devido à ausência desse fator de risco importante para DZ. Esse fato atípico pode ser justificado, em menor prevalência, por possuir DM e pelo tratamento para sarcoidose com imunossupressores. Os achados clínicos e radiológicos são inespecíficos. Nosso objetivo é demonstrar a importância do estudo da imagem, como mamografia (MMG) e ultrassonografia (USG), que pode auxiliar nos diagnósticos diferenciais e de exclusão da DZ, para descartar, principalmente, as causas neoplásicas da mama.
A espiritualidade/religiosidade na formação do pedagogo/ professor pesquisado (R) implicado: reflexões autoetnográficas
Authors: Anton Neto Florencio Reverendo , Torres Milton Luiz , Cardoso Hugo Saba Pereira
Published: February 2024

Essa pesquisa qualitativa tem por objetivo geral descrever a heurística que justifica a problemática da espiritualidade/religiosidade na construção da tese de um pedagogo/professor pesquisado (r) implicado a partir de um recorte narrativo, crítico e reflexivo de cunho autoetnográfico. Pesquisas dessa natureza requerem um novo olhar epistemológico que permita a construção de um conhecimento integrador, transversal, interseccional, não regular e transgressor, daí a aproximação com o campo socioantropológico e com a autoetnografia como reflexo de uma renovação paradigmática na ciência atual. O estudo abordou a pluralidade da condição humana do pesquisador e nesta, a espiritualidade/religiosidade, em seu lócus de crença, valor, afetividade e intersubjetividade nas imbricações com o fazer científico. Ficou evidente que a espiritualidade/religiosidade assume, entre outras, uma dimensão ontológica que confere sentido à vida, enviesa as práticas sociais entre as quais a docência e implica, como um saber, o campo de formação do pedagogo/professor pesquisado(r) sendo por isso importante incluir o tema na pauta dos interesses das pesquisas científicas em Educação e especificamente das pesquisas voltadas para a formação de professores.
Cultura Maker na educação básica: uma análise a partir da epistemologia Fleckiana
Authors: Maciel Junior Percy Fernandes , Lambach Marcelo , Niezwida Nancy Rosa Alba
Published: February 2024

O presente artigo traz um recorte de uma pesquisa de doutorado em andamento, cujo objetivo consistia em organizar um processo de formação continuada para professores da educação básica a partir da Cultura Maker (CM) que promovesse o surgimento de complicações fleckianas nos comportamentos de consumo didático dos professores sob a perspectiva baumaniana da modernidade líquida. A etapa descrita neste texto apresenta um referencial teórico que tece reflexões críticas, sob uma perspectiva progressista, à inserção da CM na educação e, fundamentada na epistemologia fleckiana, propõe um quadro teórico para a pesquisa dessa temática. A ubiquidade do conceito de “fazer” na fundamentação de todas as críticas analisadas no referencial teórico, apontou para a necessidade de se questionar a constituição dos conceitos: criatividade, pesquisa, e trabalho colaborativo/cooperativo. Embora façam parte da CM e a educação formal, possuem significados não totalmente coincidentes nesses dois mundos sociais, podendo, durante um processo de integração, ser contaminados por conceitos presentes na ideologia neoliberal. Fundamentados nos conceitos fleckianos: coletivo de pensamento (CP), estilo de pensamento (EP), acoplamentos ativos e passivos, e trânsito intercoletivo e intracoletivo de ideias, utilizamos as categorias de análise: objetos fronteiriços, conotação, tradução, e zona de interesse, para argumentar sobre a adoção dos conceitos de criatividade, trabalho colaborativo/cooperativo, e pesquisa, como elementos de um quadro teórico para pesquisa sobre o uso da CM na educação formal. A análise desses conceitos sob a perspectiva fleckiana demonstrou algumas possibilidades de interação, tanto na dimensão linguística como praxiológica, que, em nossa compreensão, proporcionam uma ampla gama de possibilidades para o desenvolvimento de pesquisas sobre o uso da CM na educação em uma perspectiva progressista.

Published: February 2024

O presente estudo tem por objeto o trabalho docente na Educação de Jovens e Adultos no Presídio Montes Claros II, cujo objetivo é analisar a capacitação da mão-de-obra docente, os métodos utilizados nesse processo, identificar os aportes financeiros do setor público e privado que são destinados à educação nos presídios do Estado de Minas Gerais, analisar as dificuldades que se apresentam no exercício da profissão, assim como conhecer a realidade do sistema prisional, em especial do Presídio Montes Claros II, como um auxílio na construção da cidadania e ao retorno desses indivíduos à sociedade. Trata-se de pesquisa bibliográfica e documental, tendo como referência o Plano Estadual de Educação para Pessoas Privadas de Liberdade e Egressas do Sistema Prisional de Minas Gerais. Acrescenta-se que são dados parciais de pesquisa para produção de dissertação no âmbito do Programa de Pós-graduação em Educação da Unimontes – PPGE/Unimontes. Observou-se que a educação dos reclusos nos presídios é realizada por meio da parceria entre a Secretaria de Estado de Educação de Minas Gerais (SEE/MG) e a Secretaria de Estado de Justiça e Segurança Pública (SEJUSP), via Acordo de Cooperação Técnica, sendo que a Educação Básica nas unidades prisionais e Associação de Proteção e Assistência aos Condenados (APACs) é ofertada através da modalidade Educação de Jovens e Adultos (EJA), além da Educação Profissional e Tecnológica, modalidades que visam a preparação do reeducando e sua reinserção na sociedade. Conclui-se que, não obstante o Plano Estadual de Educação indicar a existência de acesso à educação no interior dos estabelecimentos prisionais, não significa afirmar a presença de políticas públicas direcionadas aos educadores, o que sugere a necessidade de maior aprofundamento teórico e empírico quanto à matéria, em especial, no âmbito do Presídio Montes Claros II, área de abrangência da Universidade Estadual de Montes Claros e do Programa de Pós-graduação da Unimontes – PPGE.

A batata-doce é uma das principais fontes de alimentos para populações. Na contramão da relevância social e econômica da cultura, a facilidade na obtenção de material propagativo de baixa qualidade tem colocado em risco a qualidade e produtividade de plantios. Neste sentido, objetivou-se com este trabalho avaliar o índice de pegamento, altura média das mudas, acúmulo de fitomassa em raízes, caules, folhas e planta inteira, além do acúmulo de carbono (C) em mudas de batata-doce biofortificada ‘CIP-BRS-Nuti’, em função do número de gemas. O estudo foi realizado no setor de produção de mudas de batata-doce do IFSertãoPE, Campus Petrolina Zona Rural – CPZR, Petrolina, PE, Brasil, entre os meses de agosto a outubro de 2022. O delineamento experimental foi inteiramente casualizado, com 03 tratamentos e 25 repetições. As avaliações foram realizadas aos sete e 35 dias após o plantio (DAP). Aos 07 DAP, foi determinado o índice de pagamento das mudas (IP %). Aos 35 DAP, todas as mudas foram coletadas. Inicialmente, avaliou-se a altura média das mudas; individualmente, as mudas foram separadas em raízes, caules e folhas, pesadas com auxílio de balança de precisão para determinar a massa fresca. Após a pesagem, as mudas foram acondicionadas em sacos de papel devidamente identificados, levadas à estufa de circulação de ar forçada – 65ºC, 72h, para determinação da sua massa seca. O acúmulo de carbono (C) foi realizado considerando que 1g de fitomassa corresponde a 0,4g de C. Em todos os tratamentos foram observados IP ≥ 98%. As maiores alturas de mudas foram observadas no T2 (02 gemas); os maiores valores de acúmulo de massa fresca e seca em caules, folhas, planta inteira e C ocorreu em mudas com 02 ou 03 gemas, T2 e T3, respetivamente. Recomenda-se a propagação de mudas de batata-doce ‘CIP-BRS-Nuti’ com 02 gemas, possibilitando melhor aproveitamento de ramas-sementes.

Published: February 2024

The fish and fisheries sector plays an important role in global food security, employment and economic development. At now, with a total production of 214 million tonnes in fisheries and aquaculture, including 178 million tonnes of aquatic animals and 36 million tonnes of algae, these sectors are making an important contribution to ensuring global food security. Moreover this sector also provides employment to millions of peoples directly or indirectly and also generated higher assets. With 16.24 million tonnes of fish production in India, the sector contributes 1.1% to the Indian economy. Also the sector has become the third largest fish producing country with a contribution of 8% to the global fish production and ranks second in aquaculture production. But in present this sector faces environmental threats (overfishing, habitat destruction and climate change), economic challenges (market fluctuations, IUU fishing and limited access) and social issues (food security, gender inequality and community displacement) around the world. Therefore, to solve these challenges, a holistic approach such as sustainable fisheries management practices, climate change adaptation strategies and collaborative efforts involving governments, the fishing industry, scientists and local communities is required that may be helpful in reducing these problems. This article highlights the interconnected nature of the challenges faced by the fish and fisheries sector and underlines the appropriate step to protect this important resource for food safety, livelihood and environmental protection.

The therapeutic window of vitamin k antagonists (VKA) is narrow. An overdose can therefore easily be secondary to a slight change in dose or an interaction with another substrate. We report the case of a 48-year-old patient followed for atrial fibrillation (AF) on mitral stenosis for 20 years under well-balanced Acenocumarol, who presented with a major hemorrhagic accident at VKA following the intake of a herbal medicine based on Turmeric (contains a chemical called curcumin). This case demonstrates that curcumin can potentially cause a bleeding event with VKAs. Clinicians should have the reflex to look for such interactions on interrogation in order to avoid recurrence and to ensure the efficacy and safety of anticoagulant therapy.

Published: February 2024

Background: Nowadays Veterinarians and poultry producers use antibiotics to increase growth rates, bird health, and feed efficiency, egg production, for preventative and therapeutic purposes, and to lessen the prevalence of poultry diseases. Most poultry producers have used a variety of antibiotics, either with or without veterinarian instruction. Although antibiotics are beneficial for the majority of their uses, their unauthorized use has resulted in residues accumulated in poultry products intended for human consumption which represent a serious risk to the general public that could be toxicological, microbiological or immunological.
Aim: This study aimed at estimation of the residues of three major antimicrobial used in the intensive chicken rearing systems in Egypt, namely Oxytetracycline, Gentamicin, Ciprofloxacin. Moreover, the effect of cooking on such residues was investigated.
Methods: A total of 100 chicken meat samples (breast, thigh, gizzard, liver, 25 each) were examined for detection of the aforementioned antimicrobials using the microbial inhibition assay and HPLC. Besides, samples containing the highest antimicrobial residues were examined for the effect of boiling for 30 min on such residues.
Results: The obtained results revealed that 23%, 21%, and 17% of the examined samples were positive for oxytetracycline, gentamicin, and ciprofloxacin residues, respectively. As for cooking (boiling) for 30 minutes showed reduction of the antibiotic residue by 88.2%, 95.2%, and 31.3%, respectively.
Conclusion: Antimicrobial residues were detected in the chicken meat parts retailed in Egypt. Cooking can reduce the antimicrobial residues at least in part.

Dende idades moi temperás estamos rodeados de estímulos que nos inflúen nas decisións que tomamos. É moi sinxelo atopar nenas e nenos que deciden ser cantantes, dedicarse ao mundo do deporte ou da medicina, mais pola contra, moi poucos son os que teñen claro que queren formar parte do mundo da ciencia. Un grupo de rapaces e rapazas que decidiron levar a cabo ese soño infantil, foron quen de formar a Sociedade Xuvenil Galega de Química, SXGQ. Grazas a eles, moitos outros poden transmitirlle aos seus familiares e amigos como é a verdadeira cara da investigación, derrubando os prexuízos que a ciencia foi adquirindo ao longo dos anos. Deste xeito a SXGQ, trata de levar a ciencia aos colexios, ás familias e á sociedade, e sempre en galego, demostrando que a ciencia en galego existe. Neste traballo preténdese mostrar como é a SXGQ, por que se formou, que facemos e a repercusión que estamos a ter.

Temperature and Water Level Controlled Steam Therapy Equipment
Authors: Bhagyawant Shraddha , Shinde Arohi , Kasambe Dr. Prashant
Published: February 2024

Steam Therapy is a treatment method used extensively in the healthcare industry. Steam has numerous benefits which is why it is used in the healthcare industry. With the context of our project, we are focusing on the steam therapy used mainly by the physiotherapist for the treatment. There exists a steam therapy equipment which is used for the treatment, but is not user friendly. The current equipment does not consist of temperature control, water level indication and auto power on and off, because of which one needs to manually look after it. To make it more user friendly with less human intervention, we propose to develop a steam therapy equipment. We plan on adding various features to the existing model. The features are temperature control and water level indication. Our focus is to mainly remove human intervention as much as possible and make the equipment as smart as possible. To implement the prototyping of the above we have considered the ATmega328p microcontroller, DS18B20 as the temperature sensor and a Force sensor. Hence, to tackle the issues faced by the physiotherapist we plan to devise this model. Keywords—temperature control, water level indicator, microcontroller, force sensor

The objective of this study is to investigate the adoption of met-averse education in Ho Chi Minh City, Vietnam, by employing the Theory of Planned Behavior (TPB) as the foundational theoretical framework. Metaverse education, utilizing immersive and interactive virtual environments for educational objectives, is an innovative and auspicious methodology in the contemporary digital realm. Data collection was conducted via judgmental sampling. Partial least squares structural equation modeling was used for the analysis. The results suggest a significant and positive impact of Consumer Intention (CI) on the practical use (AU) of the met-averse in the field of education. Furthermore, the factors of Perceived Behavioral Control (PBC), Subjective Norm (SN), and Perceived Value strongly influenced Consumer Intention (CI) in a positive manner. Moreover, Emotional Value (EV) and Social Value (SV) had a substantial impact on the Perceived Value (PV) of using the metaverse in educational contexts. Nevertheless, the lack of statistical significance in the relationship between Attitude towards Behavior (ATB) and Consumer Intention (CI) is recognized. This research not only addresses a significant gap in the theory of IS literature but also offers valuable insights for educators, policymakers, and developers. If you really understand the things that make people open to metaverse education, you can make big changes to plans and actions that are used to successfully add metaverse education to the regular school setting, especially in Ho Chi Minh City, Vietnam.

The purpose of this study was to examine the impact of behavioral biases, such as overconfidence, disposition effect, herding, risk aversion, and financial literacy, on investment decision making. The sample was collected using a convenient method, and 338 respondents participated in the study. The study utilized descriptive statistics, ANOVA, independent sample t-tests, correlation, and linear regression analysis to analyze the data. The findings of the study suggest that overconfidence, disposition effect, and risk aversion have a significant positive impact on investment decision making, while herding does not have a significant effect. Furthermore, the results indicate that financial literacy moderate’s overconfidence, disposition effect, risk aversion, and herding negatively. This implies that higher financial literacy levels can help mitigate the impact of these biases on investment decisions. The study provides valuable insights for policymakers, stakeholders, and financial institutions to develop policies and strategies aimed at improving financial literacy. It can be useful for researchers and the general public as well, as it provides a deeper understanding of the behaviour bias and investment decision. Future research can broaden the scope of the study by including new independent variables, such as loss aversion and confirmation bias. Additionally, future research can explore the moderating effect of other factors, such as age and gender, on the relationship between behavioral biases and investment decision-making. Overall, the study highlights the importance of understanding and managing behavioral biases in investment decision making, and suggests that increasing financial literacy can help individuals make more informed investment decisions.

Introduction: Adolescents contribute to one fifth of the world's population and is a high priority lifecycle stage for nutrition needs and intervention. Nutritional deficiency, including micronutrients, hinders their normal growth and development. Improving adolescent girls’ nutrition has reproduction-related benefits and serves as a unique opportunity to break the vicious cycle of intergenerational structural problems. The objective is to estimate the prevalence of anaemia, micronutrient deficiency and nutritional status among adolescent girls in rural India.
Methods: A community-based cross-sectional study was conducted among 241 adolescent girls in rural Tirunelveli, India with 220 blood samples.
Results: The mean age of 241 adolescent girls was 13.8±1.4 years and nutritional status was normal, overweight, obese, thin and stunted in 81.7%, 14.5%, 3.3%,0.4% and 4.6% respectively. The prevalence of anaemia, iron deficiency and iron-deficiency anaemia were 37.2%, 34.5% and 12.3%. Except for selenium, the estimated micronutrient deficiency levels were Vitamin B12 - 40.9%, Copper-30.9%, Zinc-13.6% and Iodine- 11%. Only 19.1% girls had adequate levels of all micronutrients. Vitamin B12 deficiency was more in girls who were overweight (p<0.05).
Conclusion: Multiple micronutrient deficiency with normal nutritional status is high among adolescent girls with Vitamin B12 deficiency higher than Iron. Multipronged strategies, including introducing micronutrient fortified healthy snacks in schools, might bring greater acceptance and improvement in nutritional health among these girls.

Application of geochemical proxies to vein minerals - particularly calcite - can fingerprint the source of fluids controlling various important geological processes from seismicity to geothermal systems. Determining fluid source, e.g. meteoric, marine, magmatic or metamorphic waters, can be challenging when using only trace elements and stable isotopes as different fluids can have overlapping geochemical characteristics, such as δ18O. In this contribution we show that by combining the recently developed LA-ICP-MS U-Pb calcite geochronometer with stable isotopes (including clumped isotope palaeothermometry) and trace element analysis, the fluid source of veins can be more readily determined. Calcite veins hosted in the Devonian Montrose Volcanic Formation at Lunan Bay in the Midland Valley Terrane of Central Scotland were used as a case study. δD values of fluid inclusions in the calcite, and parent fluid δ18O values reconstructed from clumped isotope palaeothermometry, gave values which could represent a range of fluid sources: metamorphic or magmatic fluids, or surface waters which had undergone much fluid-rock interaction. Trace elements showed no particularly distinctive patterns. LA-ICP-MS U-Pb dating determined the vein calcite precipitation age – 318±30 Ma – indicating a metamorphic or magmatic fluid source was unlikely as there was no metamorphic or magmatic activity was occurring in the area at this time. The vein fluid source was therefore interpreted to be a surface water (meteoric based on paleogeographic reconstruction) which had undergone significant water-rock interaction. This study highlights the importance of combining the recently developed LA-ICP-MS U-Pb calcite geochronometer with stable isotopes and trace elements to help determine fluid sources of veins, and indeed any geological feature where calcite precipitated from a fluid that may have resided in the crust for a period of time (e.g. fault precipitates or cements).

Growth and yield models in forest management planning are used to project future forest conditions and estimate quantities such as wood volume and biomass. These models are crucial for assessing forest sustainability, however, some models currently used in Canada do not adequately account for climate and other environmental variables, which limits their effectiveness under a changing climate. Climate-sensitive growth and yield models (CSGYMs) are therefore urgently needed to support forest management decisions. The Canadian Forest Service (CFS) has developed a strategic plan to advance climate-sensitive growth and yield modeling in Canada through collaboration with provincial and territorial agencies, as well as other partners. The primary objective of this plan is to provide a national-level modelling approach to predicting and managing forest growth, mortality, and other ecosystem services. The climate sensitive growth and yield modelling initiative emphasizes collaboration, open data, and open-source code principles to ensure widespread accessibility and uptake of models, thus contributing to the sustainable management of forest resources. This technical review reports on the status of growth and yield models currently applied in each province and territory, assesses the level of climate sensitivity associated with each of these models, synthesizes the relevant modeling approaches and input data required to implement climate sensitivity into these models, and suggests possible pathways for achieving CSGYM at a national scale. Widespread collaboration will be the key to advancing the development of CSGYMs.
