Authors: Mesquita Gonçalves Janine , Bernardes da Silva Ferreira Lara
Published: May 2024

A contaminação ambiental dos solos por metais pesados é uma realidade com o crescimento da população mundial e o aumento do descarte dos mais variados tipos de resíduos. O objetivo com o presente estudo foi avaliar a germinação e o crescimento inicial de plântulas de trigo submetidas à combinação de doses de P com doses de Cr em solução nutritiva. Para tanto, o experimento foi conduzido em delineamento em blocos completos casualizados em esquema fatorial contendo três doses de P (0,1; 1,0 e 1,9 mmol L-1) combinadas a quatro doses de Cr (0,0; 0,5; 1,0 e 1,5 mmol L-1), em quatro repetições. As variáveis analisadas foram: altura de plântulas, percentual de germinação, massa fresca da parte aérea e das raízes. Não foram encontradas diferenças significativas para a interação. A ausência de P no meio de cultivo aumentou a emissão de raízes pelas plantas, expresso pelo aumento da massa fresca de raízes nesta condição. O Cr reduz o crescimento das plântulas de trigo, com redução na altura, no percentual de germinação, na massa fresca da parte aérea e das raízes. Há necessidade de estudos mais aprofundados para avaliar a interação entre o P e o Cr no crescimento de plantas tropicais.

Introduction

Breast cancer has become the most prevalent malignant tumor among women globally, posing a serious threat to women's life and health. Neoadjuvant therapy (NAT) has emerged as one of the standard treatment approaches for breast cancer patients. However, due to varying responses to NAT among different patients, significant differences in treatment effectiveness occur, impacting the timely alteration of treatment strategies for patients.

Material and methods

Based on clinical and pathological characteristics along with the RCB scoring, we utilized a support vector machine (SVM) algorithm to construct a Breast Cancer Pathological Characteristics(PBCS) prediction model. We thoroughly validated the PBCS and compared it to a Pathomics Signatures (PS) prediction model.

Results

we developed a pathological prediction label, named PS. Subsequently, through univariate and multivariate analysis, we discovered a significant correlation between HER2 and the patients' RCB scores. Integrating HER2 into PS, we constructed a breast cancer pathological prediction model, named PBCS.PBCS exhibits good performance in predicting the effectiveness of postoperative therapy（RCB 0~Ⅰ） in both the training sets(AUC0.86[95%CI0.7988-0.9173])and validation sets（AUC0.83[95%CI0.7219-0.9382 ]). In the validation set, PBCS significantly outperforms the PS（AUC0.65[95%CI0.5121-0.7886 ]）.Calibration curves and clinical decision curves also strongly support PBCS's ability to effectively predict the efficacy of therapy（RCB 0~Ⅰ）.
Conclusions

Conclusions

PBCS can assist clinical and pathological physicians in accurately predicting patients' post-treatment RCB grading before initiating NAT. This offers a new approach to forecast breast cancer patients' responsiveness to NAT, aiding in devising personalized treatment strategies for patients.

Published: May 2024

Objective: To evaluate mortality and morbidity in HF patients receiving sodium restriction.
Study Design: Systematic Literature Review (SLR) of RCTs and Cohort studies worldwide published between Jan 2013 to Jan 2023.
Methodology: We systematically selected RCTs and Cohort studies with sodium restriction as an intervention published within the last decade from five databases (PubMed, Scopus, Cochrane Library, Embase, and Medline). The full texts retrieved were assessed for risk of bias, and then a systematic review was performed. The endpoints analyzed were mortality and morbidity.
Result: Five RCTs and two cohort studies were included in this study, with 2,505 participants. The endpoints retrieved were mortality and morbidity (hospitalization, NYHA functional class, BNP or NT-proBNP level, quality of life, and congestion). No improvement was seen in mortality and hospitalization, but sodium restriction improved the rest of the morbidity indicators. Over-restricted and overconsumption of sodium intake might worsen HF presentation. When analyzed based on the HF groups, there was not enough evidence to recommend sodium dose based on ejection fraction; however, there was potentially more benefit for patients with higher NYHA classes. However, more evidence is still needed.
Conclusion: Sodium restriction did not benefit mortality and hospitalization but improved quality of life, systolic blood pressure, and BNP or NT-pro BNP levels in all HF classes.

Published: May 2024

Objective: To find an association between a single nucleotide polymorphism (SNP) rs1330344 in cyclooxygenase-1 gene with Aspirin resistance in patients with cardiovascular disease in the Pakistani population.
Study Design: Cross-sectional
study Place and Duration: Pharmacology Department, National University of Medical Sciences, Pakistan, in collaboration with the National Institute of Heart Diseases and Institute of Biomedical and Genetic Engineering Islamabad, Pakistan, from Oct 2018 to Dec 2021.
Methodology: The Study was conducted on 384 patients (272 males and 112 females) with ischemic heart disease. Patients on Aspirin for at least seven days were selected. Platelet aggregation was performed using a Light Transmission Aggregatometer and arachidonic acid as an agonist. DNA extraction was done using the kit method (Invitrogen, Thermofisher). Then, Polymerase Chain Reaction, Restriction Fragment Length Polymorphism, and gel electrophoresis were used to identify SNP rs1330344.
Results: In this study, 14.0% (n=54) and 86.0% (n=330) of ischemic heart disease patients were resistant to Aspirin and Aspirin, respectively. The genotyping of Cyclooxygenase 1, SNP rs1330344 showed 24.41% (n=94),17.56% (n=67), and 57.98% (n=223) patients had wild type allele (CC), homozygous (TT) and heterozygous (CT) genotype respectively. Gel electrophoresis results for allelic identification were correlated with the anti-platelet efficacy of Aspirin among ischemic heart disease patients. No association was found between a polymorphic form in SNP and the development of aspirin resistance.
Conclusion: Aspirin resistance is not associated with any specific polymorphic form of Cyclooxygenase-1 at SNP rs1330344 in the Pakistani population.

Study Design: Comparative cross sectional study
Place and Duration: Armed Forces Institute of Rehabilitation Medicine from July to December 2021.
Methodology: Adults of age ≥18 years, admitted in amputee ward of AFIRM with lower limb amputation (traumatic or non-traumatic, unilateral or bilateral, new or follow up cases) were included in the study. All patients were undergoing DEXA scan for the first time since amputation. Patients were divided into 3 groups: transtibial amputation (TTA), transfemoral amputation (TFA) and ankle/foot amputation groups. Z-scores were documented for lumbar spine (L1-L4) and neck of femur (NOF). Z-scores at NOF were documented on amputated as well as non-amputated sides.
Results: A total of 47 patients participated in the study. All were male. Mean age of patients was 30.8 ± 7.1 years (Range: 21-48 years). Majority of the patients (n=28, 59.6%) had left lower limb amputation.  Out of 47 patients, TTA group comprised of 37 (78.7%) patients, TFA group comprised of 3 (6.4%) and ankle/foot group comprised of 5 (10.7 %) patients. Independent sample t-test was applied to determine the difference in Z-scores at NOF between amputated and non-amputated side in TTA group and result was statistically significant (p <0.001).
Conclusion: A significant number of lower limb amputees suffer from reduced BMD. This is the well identified risk factor for NOF / hip fractures. Health care professionals must understand the significance of identifying amputees with low BMD.

Published: May 2024

Objective: To assess whether monitoring the peak systolic velocity (PSV) in the middle cerebral artery (MCA) was a useful, non-invasive method for predicting anaemia in fetuses.
Study Design: Cross-sectional study
Place and Duration of Study: Armed Forces Institute of Radiology, Rawalpindi Pakistan, from Feb and Aug 2022.
Methodology: Fifty pregnant women who did not have hydropic babies were included. The peak systolic velocity (PSV) was measured in the middle cerebral artery (MCA). A positive result was determined when the MCA-PSV value exceeded 1.5multiples of the median (MoM). The blood samples obtained from neonates were forwarded to the hospital laboratory to estimate haemoglobin levels shortly after birth. The outcome of the method (MoM) was observed and subsequently compared with neonatal haemoglobin levels.
Results: 60% of neonates were anaemic according to middle MCA-PSV while the haematology laboratory reported 74% of neonates as anaemic according to cut-off haemoglobin of less than 13.5gm/dl. Sensitivity, specificity, positive predictive value(PPV), negative predictive value (NPV), and accuracy of the MCA-PSV in detecting the anaemia were 93.75%, 61.1%, 81.08%, 84.62%, and 82%, respectively.
Conclusion: MCA-PSV Doppler is deemed valuable as a diagnostic technique for fetal anaemia, albeit secondary to the primary approach of neonatal haemoglobin estimation upon birth.

Runoff Management based Water Harvesting for Better Water Resources Sustainability: A Comprehensive Review
Authors: Doost Ziaul Haq , Alsuwaiyan Mohammad , Yaseen Zaher Mundher
Published: May 2024

The exacerbation of drought conditions has significantly enhanced water scarcity, notably impacting arid and semi-arid regions globally. Consequently, effective runoff management has emerged as a critical and formidable challenge. This comprehensive review addresses the critical challenge of runoff management for water resources sustainability, specifically through the lens of dam site selection employing MCA. A systematic investigation into the origins and methodologies of runoff management highlights the prevalent application of MCA models, with an in-depth literature review providing insights into various approaches, their advantages, limitations, and suitability for specific contexts. Through an extensive literature review, 63 criteria affecting dam site suitability were identified and analyzed, with slope, land use/land cover, and soil type identified as the most significant factors. The findings revealed an exponential increase in the application of MCA for dam site selection over the past two decades, emphasizing its growing importance in the field. Further, the review highlights the varied outcomes of dam site evaluations due to differing expert opinions on criteria weightings, pointing to the necessity for a unified approach to criteria weighting. It is recommended that future research focus on harmonizing these weights and incorporate high-resolution observational data to enhance the accuracy of dam site suitability assessments. Moreover, the integration of climate adaptability into runoff management models is suggested to ensure long-term water resource sustainability. This comprehensive review not only outlines the current state and challenges in runoff management and dam site selection but also proposes a direction for future research aimed at resolving these critical issues.

Published: May 2024

This article analyzed the business growth strategies for the positioning of a small company located in the parish of Calderón, Ecuador, where the main problem is the abundant competition and economic concentration since there is a large number of businesses engaged in the same economic activity. Due to the limited implementation of business growth strategies, which are implemented empirically and without sufficient preparation by the firms, this article aims to understand how business growth strategies affect the positioning of the selected firm, i.e. the Comercial la “J”, located in the Ecuadorian parish of Calderon. For this purpose, it was considered to use the types of field research, bibliographic and descriptive, with a mixed approach; applying research methods: inductive, deductive, analytical and statistical; and data collection techniques through interviews and surveys. With the development of the fieldwork where it was possible to identify the business growth strategies used by the small firm and using the corresponding research techniques, it is recommended to compare the strategies with those adopted by direct competitors and similar businesses, in order to identify good practices and opportunities for improvement. Regarding the results, it could be noted that the small firm analyzed is the second best-positioned store in the market, while it has a 53% probability of recommendation by its customers, which can help it to be a leader in the market.

The aim of this study was to investigate the influences of stress levels and physical activities on primary dysmenorrhea. A cross-sectional was conducted in Cirebon, Indonesia, in 2023 included young women who had never given birth (nullipara), aged 17–25 years old, had menstruated, and had no history of smoking and alcohol. The data were collected using a set of questionnaires consisting of the Numeric Rating Scale (NRS) to determine primary dysmenorrhea pain, the Depression Anxiety Stress Scales 42 (DASS 42) to determine the level of stress and the International Physical Activity Questionnaire (IPAQ) to determine physical activity. Pearson's correlation test was used to assess the correlation between the variables (stress levels, physical activity, and dysmenorrhea). A total of 150 young women were included in the study. Moderate stress levels (23.3%) and high physical activity (90.7%) were the most prevalent categories observed among studied participants. Approximately 42% of them experienced mild dysmenorrhea pain. Our analysis indicated that stress levels and physical activities had strong positive correlations with dysmenorrhea pain levels, with r=0.782 and r=0.748, respectively, with both had p<0.001. This highlights that controlling stress could be beneficial in preventing dysmenorrhea pain among young women.
