The city of Santo Amaro (Bahia, Brazil) gained visibility among the scientific community due to the contamination of the Subaé River by lead and cadmium from the PLUMBUM Mineração e Metalurgia Ltda industry, on the banks of the river in 1956, which produced lead ingots The present work aimed to investigate the adsorption capacity of heavy metals (Pb and Cd) of EPS produced by bacterial species from the Subaé River, for possible future application of these biopolymers in bioremediation processes in areas impacted by the aforementioned heavy metals. Subaé river water was collected for physical-chemical analysis and bacterial isolation. It was verified that all isolated bacteria produced an expressive amount of Exopolysaccharide (EPS). Thus, the optimization of this production in different sugars (sucrose, glucose, and mannitol) and in three different pHs: 5.5; 6.5, and 7.5. All bacteria produced EPS in large quantities and the best sugar was sucrose at pH 7.5. In order to use the EPS for the bioremediation area, the adsorption test of lead and cadmium was carried out by the isolated EPS. 0.5 g of the EPS was dissolved in 50 ml of deionized water, then the solutions of metals, lead acetate, and cadmium sulfate (procedure performed separately) were incubated at 28 °C for 16 h after that period, and were centrifuged. Samples were filtered to separate the insoluble EPS and the filtrates obtained were used in the quantification of the metals by atomic absorption (FAAS- Flame Atomic Absorption Spectrometry). Bacillus spp., Bacillus cereus, Staphylococcus spp., and Serratiamarcescens, all showed tolerance to the tested metals, due to the efficiency in the adsorption capacity of the EPS, and it was possible to distinguish seven genera, Klebsiella pneumonia, Pseudomonas aeruginosa, Lysinibacillus spp. to be used in the bioremediation of environments contaminated with heavy metals.

This study conducted an elemental analysis and assessed heavy metal concentrations in five powdered milk samples (V1, L1, H1, G1, and D1) from Senegal, utilizing X-ray Fluorescence (XRF). The analysis focused on aluminum (Al), calcium (Ca), potassium (K), phosphorus (P), and chlorine (Cl). Aluminum was either undetected or found at negligible levels in all samples. Calcium levels consistently surpassed the Acceptable Maximum Level (AML) in all samples, with H1 exceeding the AML by approximately 11.1 times (27,745.06 ± 310.16 ppm). Potassium concentrations varied, with G1 exhibiting the highest levels, significantly exceeding the AML (51,058.15 ± 456.13 ppm), while V1 remained within acceptable limits. Chlorine concentrations generally complied with the AML, except for G1, which slightly exceeded the limit (3631.04 ± 31.23 ppm). Phosphorus concentrations in H1 were notably higher than the AML (13,750.94 ± 275.35 ppm). The non-uniformity in heavy metal concentrations among samples emphasizes the need for ongoing research and regulatory scrutiny to address potential risks and ensure the safety of powdered milk.

The research creates a theoretical basis for examining the metamorphic changes and transformations in urban and housing planning with the interaction created by the latest epidemic in the world, which is moving towards a period related to climate problems. The first quarter of the 21st century witnessed an unexpected event: Humanity found itself in the middle of a pandemic considered temporary, it would be permanent and change the world dramatically. The post-COVID-19 period has led to significant and permanent changes in our lives, from urban planning to housing typologies. The study aims to understand the changing dynamics in the post-pandemic period that converges on the same goal with SDG, (Sustainable Development Goals), as continuity by updated dialogues, and discourses on literature. This research focuses on the SDG, (Sustainable Development Goals), and the post-pandemic period, analysis of two phenomena separated, analogous paradigms or intertwined. The findings of the public perception are there is a distinction between sustainability and pandemics considered dissimilar processes, they contain similarities. Contrary to common ideas, the pandemic was a catalyst for sustainability, and these two concepts contain analogous ideas and principles. In conclusion, it is revealed that they both concentrated on similar ideas; SDG, (Sustainable Development Goals) is “health”, and pandemic is the “healthy city” concept like; clean air, zero carbon, living healthy and safely in airy and green areas, etc.

Lead telluride (PbTe) is considered one of the most promising materials in thermoelectrics due to its unique thermoelectric properties. This semiconductor exhibits a high thermoelectric figure of merit (ZT) in certain temperature ranges, making it highly effective for converting heat energy into electricity. Additionally, PbTe is characterized by stability and low thermal conductivity, which further enhances the efficiency of thermoelectric devices. Another advantage of using PbTe is its relative affordability and high availability of raw materials. This makes it attractive for manufacturing mass thermoelectric devices such as thermoelectric modules for automobiles, industrial thermoelectric generators, heat recirculation, and others. The paper provides a review of works and an analysis of general approaches to semiconductor thermoelectric materials, including lead telluride.

Nutritious and safe foods are essential to meet normal physiological and metabolic functions. This study evaluated heavy metals in selected food products for newborns and toddlers. These substances may result in adverse health risks and young children are extremely vulnerable due to their immature immune systems and organs. Industrialization and technological advancement have contributed to an increase in heavy metals in the soil; therefore, entering the food system in potentially harmful amounts. Safe levels have been established by monitoring agencies to reduce the presence of heavy metals. Ten national brands of baby foods were analyzed for selected heavy metals. The main ingredients ranged from vegetables, fruits, dairy, poultry, meats, and grains. The products were analyzed in triplicates using QQQ-ICP-MS instrumentation to detect the presence of arsenic, cadmium, zinc, lead, nickel, aluminum, and chromium. Based on the Agency for Toxic Substances and Disease Registry [1] guidelines for safe quantities, aluminum (4.09 µg/g and 2.50 µg/g) and zinc (33.5 µg/g 69.5 µg/g, and 30.2 µg/g) exceeded the recommended levels of 1 µg/g/day and 2 - 3 µg/g /day respectively. Mixed model analysis found significant differences in metal concentrations (F6,24 = 2.75, p = 0.03) with an average metal concentration of 0.96 µg/g. However, no significant correlations were found between the packaging materials used and the observed metal concentrations in the food samples. The study concluded that the presence of heavy metals may be due to food type and the soil on which it is grown and not the packaging materials, establishing food system contamination by heavy metals.

Introduction: Permanent vascular access (arteriovenous fistula (AVF), arteriovenous graft (AVG)) is susceptible to acute events that reduce patency. The temporary central venous catheter (CVC) constitutes bridging therapy for primary vascular access dysfunction. The impact of “residence time” on the rate of dysfunction/thrombosis or infection remains to be explored.AIM: 1) To evaluate the impact of CVC residence time on outcomes (infection or Thrombosis/dysfunction) in consecutive temporary CVCs adjusted for the insertion site (upper site vs. lower site).2) To establish a cut-off resident time.Patients and methods: Seventeen prevalent hemodialysis patients with three consecutive CVCs are followed up prospectively in an observational study for a period equivalent to the permanence of the CVCs. The data is recorded at the beginning of the CVC time. The diagnosis of catheter-related bloodstream infection and thrombosis/dysfunction is made following the K-Doqi 2019 guidelines.Statistical analysis: Seventeen hemodialysis patients (51 CVCs) were included. The ‘CVC resident time’ of each individual patient ((i.e. βcoefficient (log-transformed)*AUC)) was determined using LMM and then inserted into multivariate Cox models to assess infection and dysfunction/thrombosis outcomes (Joint Models). The AUC was calculated at various baseline levels of CVC time (10th……50th percentile). The cut-off point for thrombosis in CVC time corresponds to the mean of the CVC time at the 30th percentile of all CVCs.Results: The CVC time is different for CVC’s site insertion and sequence. From the analysis of multivariate joint models, CVC resident time appears not to be significant for infection, but heterogenicity for the insertion site (ref3-4=upper site) is significant for the outcome of thrombosis/dysfunction. From the study of survival analysis, the free survival from outcomes by CVC site insertion appears to be significant for thrombosis/dysfunction. The average time of CVCs’ calculation at the 30th percentile is 14 days (cut-off).Conclusion: No tunneled hemodialysis Catheter (NTHC) residence time is considered not to be a risk factor for infection, but it represents a risk factor for lower access thrombosis. After the cut-off time of 14 days, the advantage of the higher NTHCs is lost.

The authors are searchers in psychopathology and communicate here about the dead wishes in relation to euthanasia. In Europe, the question comes regularly up to know if the law should be changed concerning the prohibition of euthanasia. The health system obeys progressively a modern idea of comfort and the “good life”. The authors are psychotherapists and their methodology is based mainly on phenomenological psychology, psychoanalysis, and psychopathology. Statistics of the French Ministry of Health will support their statements. Different clinical experiences with young patients, aging patients, or near-to-death patients are crossed and compared to those marked by heavy experiences like rape or amputation. The unbearable nature of their suffering makes them ask frequently to stop the pain. They would prefer being dead. This contribution examinates this kind of demand to find a helpful position for the caregiver and the patient. We should consider that near-death patients may often be at the climax of anxiety and depression is likely to switch over to dementia. In asking to finish with life, this purpose may change one day to another – sometimes it just highlights the wish to see things changed. The position of society and the medical staff has a high influence as well. Asking for euthanasia shows the variety of the same words that have different meanings from a medical, psychological, or psychopathological viewpoint. The purpose is to consider these aspects with the patient’s demand.

Background: Systemic sclerosis-associated pulmonary arterial hypertension (SSc-PAH) is characterized by pulmonary arterial remodeling resulting in right ventricular failure and death if untreated. Despite therapeutic advances, there is survival variability within the SSc-PAH population. The aim of this study was to delineate high-risk subgroups of SSc-PAH using readily available clinical parameters.Methods: We analyzed data from the PHAROS database, a prospective observational registry of incident SSc-PAH patients. Latent class modeling was performed based on trends in 6MWD over time. We compared survival between the clusters regarding baseline clinical parameters and changes in these parameters over time.Results: We identified four unique groups within 103 patients meeting our inclusion criteria, based on trajectories of 6MWD. Patients in Cluster 4 exhibited a decline in 6MWD over time and had the worst prognosis with a median survival of 3 years. Patients in Cluster 3, with the lowest baseline 6MWD, were associated with lower median survival (5 years) when compared to Clusters 1 and 2 (> 9 and 7 years, respectively), despite an improvement in 6MWD over time. There were no meaningful changes in SF-36 and WHO functional class between the clusters, but BNP trended higher over time in the higher-risk clusters. Conclusion: We identified high-risk subsets of SSc-PAH characterized by significantly worse survival. Incident SSc-PAH patients with a decline in 6MWD over time or low baseline 6MWD had worse survival when compared to SSc-PAH patients who demonstrated relatively stable or mild reduction in 6MWD over time.

Forensic laboratories face a backlog of case files, affecting service delivery, causing delays. The backlog points to underfunding, poor planning, and inadequate support, hindering deoxyribonucleic acid (DNA) analysis. Resolving casework backlogs may initially seem like a straightforward and attainable measure to improve the arrest of offenders and promote justice. Longer turnaround times impede investigative leads, emphasising the need for efficient strategies and a comprehensive approach to address and prevent backlogs in forensic laboratories. No study has been published on the forensic DNA backlogs in South Africa. The article explicitly addresses one aspect of a Doctor of Philosophy study and aims to ascertain the impact of backlogs in forensic DNA case entries. The study article’s research questions included the following: “What cases are considered as backlog?”; “What is the current backlog in forensic DNA case entries in South Africa?” and “What are the main reasons for the backlog of cases involving forensic DNA?” The prompt processing of DNA evidence is vital not only for safeguarding individuals falsely accused of crimes based on circumstantial evidence but also for aiding prosecutors and providing justice for crime victims.

Objective: To determine the factors influencing completion of DOTS in Tuberculosis treatment in the Bahamas.Methods: A quantitative, descriptive cross-sectional survey. Tuberculosis patients aged 18 years and above were considered regardless of the site or the smear status of their TB. The sample size was 40. Data analysis and interpretation were done using the statistical package for the social sciences software (SPSS version 24), through the exploration and calculation of descriptive (frequencies, percentages, means, standard deviations, and inferential (Anova) statistical methods. Statistical significance was determined to be a p < 0.05. Results: The mean age of the respondents, was 39.9 years, SD 11.65, and 73% of them were men. 63% of participants, 78% of whom were citizens of the Bahamas, reported having no annual income. Seventy-eight percent (31) of the participants said they had insufficient food and drink while they were unwell. More than half of the participants in the survey reported being on at least one pharmaceutical regimen, although 36% said they were not actively taking any of the prescription medications.Conclusion: Less than a third were noncompliant with DOTS, this was influenced by factors such as annual income, no family support, marital status, employment status, and educational level.

Phyllanthus amarus Schum. and Thonn., a plant of substantial medicinal significance, is known for its usage in the ‘Ayurvedic’ system of medicine for over 2000 years. This herb grows throughout the world including India. P. amarus along with other species of its genus has been a vital part of several herbal formulations available in the Indian market under the trade name Bhuiamlaki. Several pharmacognostic evaluations over the years established the genus Phyllanthus of great commercial value. Ethnopharmacological studies conducted with P. amarus to date have shown its diverse therapeutic usage globally. This owes to the vast array of secondary metabolites present in the herb, substantially in the leaf tissue. Different analytical and phytochemistry studies performed across the globe revealed that P. amarus is a hub of various classes of secondary metabolites viz. lignans like phyllanthin, hypophyllanthin, flavonoids, alkaloids, triterpenes, sterols, volatile oil, ellagitannins including simple and complex tannins, etc. Different analytical techniques have been employed over the past years for isolating and studying these varied secondary metabolites. Further, bioactivities and pharmacological properties of P. amarus that were mainly due to the presence of these wide arrays of secondary metabolites have also been explored extensively across the globe by several research groups. This plant has also been explored at molecular and transcriptome level, although relatively lesser but its extensive molecular and transcriptome analysis have only been performed from our lab. Thus, P. amarus has considerable potential to be explored in the future as a significant therapeutic source not only in the traditional medicinal system but also in the modern pharmaceutical industry.

Spinal muscular atrophy is an autosomal recessive neuromuscular disorder characterized by progressive muscle weakness and atrophy. It is one of the most common single-gene disorders with an incidence rate of approximately 1 in 10,000 live births. The clinical manifestations are progressive hypotonia and muscle weakness due to the degeneration of alpha neurons in the anterior horn cells of the spinal cord and motor nuclei in the lower brain stem. Depending on the severity of the symptoms, SMA has five subtypes. Supportive measures can be offered for respiratory, gastrointestinal, and musculoskeletal complications. Carrier testing for all couples is recommended and this can be done by Multiplex Ligation-dependent Probe Amplification (MLPA). Prenatal diagnosis can be offered to carrier couples. Therapies must be given within the newborn period for maximum benefit and before the loss of motor neurons. It is achieved by identifying the SMA babies through Newborn screening. Several new FDA-approved drugs can reduce the progression of symptoms in SMA. However, they cannot offer a definite cure. Clinical follow-up and Neurological assessment demonstrate that SMA children can attain developmental milestones after receiving treatment, which is never normally attained in untreated cases. In utero SMA treatment with Zolgensma would enhance the survival rate and favorable neurological outcomes in the future. Base editing and Gene editing with CRISPR-Cas technologies to target the mutations and restore functional and stable SMN protein levels are the future hopes for a permanent cure of SMA.

This study aimed to examine the disparities of childhood cancer survival among different racial and ethnic groups in Texas. The analysis was mediated by socioeconomic status (SES) and spatial accessibility to Children Oncology Group (COG) hospitals. The relationship between race-ethnicity and overall survival was measured using the Cox proportional hazards model with a robust variance estimator. The counterfactual model measures the total effect of race-ethnicity on survival through all mediating pathways while adjusting for baseline confounders (age, sex, and stage at diagnosis), which are then decomposed into natural direct and indirect effects. Considering all cancer site groups, African Americans showed a statistically significant higher hazard ratio in death (HR = 3.63; 95% CI = 1.87 - 6.62) compared with non-Hispanic White children. At the same time, the mortality hazard ratio among Hispanic children is not significant (HR = 1.23; 95% CI = 0.80 - 1.93) when compared with non-Hispanic White children. Analysis results also suggested that both mediators significantly contribute to racial-ethnic survival disparities for specific cancer site groups such as Leukemia for African American children. This study builds knowledge and understanding about underlying factors (mediators) responsible for the disparities in the outcomes among childhood cancer patients.

Background: Cancer treatment frequently depends on the intricate and potent effects that are acknowledged for their potential to save lives. Chemotherapy can have adverse effects on both the central and peripheral nervous systems, posing significant challenges.Objective: •    To assess the causative agent, development, and timing of occurrence.•    To improve management of neurological complications.•    To discriminate the iatrogenic effects of cancer therapy and neurological progression.Method: A prospective observational study was conducted in a hospital setting, focusing on the neurotoxic effects of chemotherapy in cancer patients over a span of six months. The research involved participants from both the oncology in-patient and daycare departments. After obtaining informed consent, individuals in the study population were interviewed to gather information about any neurological symptoms they encountered following their chemotherapy sessions.Results and discussion: Within our study population, a predominant 67% comprised female patients, while male patients constituted 33%. Of the total participants, 66% reported experiencing neurological symptoms. Among these symptoms, the majority of patients encountered sensations such as tingling, numbness, and a burning sensation. Other reported symptoms included headaches, distal weakness, myalgia, seizures, and ataxia.Conclusion: In this current study, 66% of the study population encountered neurological side effects. Generally, the presence of comorbidities, vitamin deficiencies, and advanced age can significantly contribute to the development of peripheral neuropathy. Depending on the severity of neuropathy, recommendations for interventions include the prescription of vitamin supplements, calcium supplements, duloxetine, and pregabalin.

The present study aims to assess and compare the quality of drinking water according to WHO Standards and then illustrate the resulting diseases. Eight samples have been taken from selective different schools in the Mount Lebanon Region. The laboratory tests of the collected samples were performed to determine various physical (e.g., temperature, pH, electrical conductivity, etc.), chemical (Ca+2, Cl-, Fe, Mg2+, NO3, Na+, SO2-4), and microbial such as E. coli, coliform, and non-coliform. Several techniques were used for the analysis including Atomic Absorption Spectrometry, Flame Photometer, and Total Organic Carbon (TOC). The resulting water quality was compared with the standard limits. Each school has different defects according to specific contamination that existed. To save local residents and according to the results of this study, regular monitoring for water quality was proposed; besides more water filtration plants should be installed to provide safe drinking for children’s health.

This study examines the intricate interplay among poverty, unemployment, education, and rural-urban migration in Nigeria, employing both quantitative and qualitative analyses. Quantitative data were analyzed using SPSS software, computing descriptive and inferential statistics such as regression analysis. Quantitative findings reveal income inequality, with many individuals earning below average. Education emerges as a key determinant of economic opportunities, with higher education associated with better outcomes. Moreover, poverty and unemployment exhibit a strong positive correlation with adverse outcomes, emphasizing the need for targeted interventions. Qualitative insights delve into the motivations behind rural-urban migration, shedding light on the economic drivers compelling individuals to seek opportunities in urban areas. Participants’ narratives uncover the challenges faced by migrants, from housing to accessing essential services. Additionally, the role of remittances in sustaining sending communities is highlighted, underscoring their significance. This study underscores the multidimensionality of poverty, unemployment, and migration and emphasizes the need for holistic, evidence-based approaches to promote inclusive development. Recommendations include investments in education, job creation, social safety nets, income inequality reduction, and support for migrant integration. These measures can contribute to equitable economic growth and improved well-being in Nigeria.

The rising prevalence of chronic diseases and the aging population globally are diminishing the overall quality of life, especially for those with demanding daily routines. As medical advancements extend lifespans, the proportion of individuals over 60 is set to double by 2050, necessitating societal shifts toward health-responsible citizenship. Despite longer lifespans, evidence suggests that older age often accompanies mental health challenges such as anxiety, depression, and substance misuse. Social isolation and loneliness further compound these issues, affecting both physical and mental well-being. Digital wellness empowers individuals to take charge of their health, promoting proactive care and literacy to foster health-conscious citizenship. This paper explores the intersection of mental health, aging populations, preventive wellness initiatives, and health literacy, emphasizing their significance within the Health 5.0 framework, especially for older adults. Traditionally, health regulators offer static workflows for adopting standard procedures in health and well-being, reflecting a reactive approach. However, the evolving landscape of wearable and mobile devices connecting to healthcare IT systems through secure online networks necessitates a shift. Technology now facilitates remote patient monitoring and telemedicine service subscriptions and empowers individuals to manage their health proactively.The BE4YOU project, conducted in Portugal, serves as a case study, facilitating individual maintenance of health and well-being through intelligent and dynamic workflows, which are defined based on analytical models considering each person’s risk profile. By facilitating data sharing, promoting healthy lifestyles, and enabling early detection of mental health issues, the project leverages technology to support personalized monitoring and enhance overall health outcomes. Through technology-driven empowerment, individuals and healthcare professionals are better equipped to assess risks and ensure ongoing wellness monitoring, underscoring the role of technology in fostering personal health and supporting healthcare effectiveness.

Worldwide, statistical data of people infected by COVID-19 has been taken until March 29, 2023, which, when correlated, showed a predictive logistic  model. The purpose was to determine the predictive model, which was acceptable, in such a way that the proportionality constant and the correlation and determination coefficients are of great importance to estimating epidemiological and pandemic data; coinciding with what was reported by other authors. Bearing in mind that a mathematical model is a mathematical description through a function or equation of a phenomenon in the real world; whose purpose is to understand infections and make predictions for the future. The stages were: to model the number of people infected as a function of time, formulate, and choose the logistic model, determine the model and obtain mathematical conclusions, and make predictions (estimates) about the number of people infected by COVID-19 worldwide. The logistic model was derived to predict the speed of people infected by COVID-19 and the critical time (tc = 733 days) for which the speed was maximum (1694,7209 infected/day). The Pearson correlation coefficient for the time elapsed (t) and the number of people infected (N) worldwide, based on 32 cases, was r = -0.88; the relationship between time and those infected is real, there is a “very strong correlation” between the time elapsed (t) and the number of people infected (N) and 77.03% of the variance in N is explained by t. 

Methyl Jasmonate (MeJA) can be used as a signal molecule to regulate the expression of resistance genes in the resistance to abiotic stress, thus improving the salt tolerance of wild jujube. Among the resistance genes combined with methyl jasmonate, transcription factors play an important role in response to salt stress. However, the interaction of transcription factors in different tissues under salt stress and the regulation of transcription factors by MeJA remain unclear. In this study, the effects of MeJA on transcription factor expression in wild jujube under salt stress were investigated, and the differences in transcription factor expression among different tissues were compared. It was found that MeJA could increase the type and quantity of transcription factors responding to salt stress. The types of transcription factors responding to salt stress were roughly the same among different tissues, but the quantity and expression of the transcription factors were significantly different. The results of transcription factor co-expression analysis showed that transcription factors play synergistic roles in the face of abiotic stress, which can provide preferable genes for subsequent transgenic work.
