In agricultural regions prone to dust storms, heavy metal contamination of soil and crops from airborne particulates poses significant risks to food safety and public health. This study has assessed the potential of machine learning models for predicting concentrations of toxic heavy metals like arsenic, chromium, and lead in dust from the agricultural Sistan region of southeastern Iran. This region experiences frequent dust storms mobilizing particulates from local dried lakes onto agricultural lands.

Postpartum depression (PPD) has been widely studied, assessed, and promptly intervened in new mothers. However, paternal postpartum depression gained attention not long ago. Postpartum depression in men could present over one year following the birth of the child, frequently presenting with symptoms like irritability, low mood, sleep disturbances, changes in appetite, fatigue, and loss of interest in everyday activities; amongst other symptoms of Major Depressive Disorder which may hinder them from taking care of themselves and the baby.

A computational study was performed to unravel mechanisms underlying capillary electrophoresis enantioseparations of daclatasvir and its (R,R,R,R)-enantiomer with native and methylated β-cyclodextrins (β-CDs) as chiral selectors. Considering the enantioseparation results as benchmark, the structures of β-CD and seven methylated β-CDs were optimized by quantum mechanics, and their topography and computed molecular properties were compared. Furthermore, the electron charge density distribution of the macrocycles was also evaluated by calculating the molecular electrostatic potential of pivotal regions of native and methylated β-CDs.

A reliable phylogeny is crucial for understanding the evolution and radiation of animal taxa. Phylogenies based on morphological data may be misleading due to frequent convergent evolution of traits-a problem from which molecular phylogenies suffer less. This may be particularly relevant in oribatid mites, an ancient soil animal taxon with more than 11,000 species, where the classification of species into high-ranking taxa such as superfamilies is equivocal.

  • The study investigated the efficacy and safety of the biosimilar BAT1806/BIIB800 compared to the reference drug tocilizumab (TCZ) in patients with moderate-to-severe rheumatoid arthritis over a treatment period of 24-48 weeks.
  • Results showed that the effectiveness of both treatments was similar, with high response rates (ACR20), along with comparable safety and immunogenicity profiles across treatment groups.
  • Overall, the study concluded that BAT1806/BIIB800 has similar therapeutic outcomes to TCZ, supporting its use as a treatment option for rheumatoid arthritis patients.

With the COVID-19 pandemic, behavioural scientists aimed to illuminate reasons why people comply with (or not) large-scale cooperative activities. Here we investigated the motives that underlie support for COVID-19 preventive behaviours in a sample of 12,758 individuals from 34 countries. We hypothesized that the associations of empathic prosocial concern and fear of disease with support towards preventive COVID-19 behaviours would be moderated by trust in the government.

Background: Healthcare workers (HCWs) have suffered considerable morbidity and mortality during the COVID-19 pandemic. Few data on COVID-19 vaccine effectiveness (VE) are available from middle-income countries in the WHO European Region. We evaluated primary series COVID-19 VE against laboratory-confirmed COVID-19 among HCWs in Georgia.

Cancer therapy advancements have improved survival rates but also introduced significant cardiotoxic risks. Cardiotoxicity, a critical adverse effect of cancer treatments such as doxorubicin, trastuzumab, and radiotherapy, poses substantial challenges. This systematic review synthesizes findings from studies on cardiotoxicity induced by cancer therapies, focusing on detection and management.

Article Synopsis
  • The study investigates the genetic relationship between Mycobacterium tuberculosis (MTB) cultures and diagnostic samples from TB cases, challenging the idea that culturing leads to loss of genomic diversity.
  • Researchers developed an advanced workflow for sequencing sputum samples and performed a detailed bioinformatics analysis to examine discrepancies between sputum and culture results.
  • Findings show a high agreement of 97% in genetic variants between sputum and culture pairs, suggesting that culturing reflects the genomic makeup of MTB accurately across various TB epidemic settings.

Article Synopsis
  • - This study explored the impact of AI-assisted contouring on radiation oncologists' (ROs) efficiency and accuracy in low- and middle-income countries (LMICs), addressing a gap in previously concentrated research from high-income nations.
  • - Ninety-seven ROs were divided into groups using either manual or AI-assisted methods for contouring organs-at-risk (OARs) in two head-and-neck cancer cases, with teaching sessions evaluating their effects on contour quality and time.
  • - Findings showed that AI-assisted contouring improved contour quality for several OARs and significantly reduced contouring time, suggesting that it is a safe and effective method, although further clinical trials are needed to fully validate these results.

With the aging population, older adults constitute a growing proportion of the new cancer cases. Given the heterogeneous health status among older adults and their susceptibility to aging-related vulnerabilities, understanding their diversity and its implications becomes increasingly crucial for prognostication and guiding diagnostics, treatment decisions, and follow-up, as well as informing supportive care interventions. Geriatric assessment and management (GAM) refers to the comprehensive evaluation of an older individual's health status with subsequent management plans focusing on both oncologic and non-oncologic interventions.

A healthy, balanced diet of a pregnant woman is an integral part for the full development of the fetus, mainly pregnant women receive the mentioned recommendations from gynecologists, because consulting a nutritionist is less mandatory at this stage still in our country. Since obesity is highly prevalent paralleling the globe, especially among the European population but nevertheless it's a preventable risk factor which is associated with negative outcomes for both mother and fetus. That's where bariatric surgery plays an important role, that has increased among women for an achievable pregnancy but being overweight prevents it.

The cohesin protein complex plays a vital role in various cellular processes such as sister chromatid cohesion, chromosome condensation, DNA repair, and transcriptional regulation. It is constituted by SMC1, SMC3, RAD21, STAG1/STAG2 subunits, and several regulatory proteins. Pathogenic variants in these components cause cohesinopathies, with common clinical features including facial dysmorphism, delayed growth, developmental delay, and limb anomalies.
