The worldwide incidence of colorectal cancer (CRC) is roughly two million new instances each year throughout the world, according to the World Health Organization 2022. CRC is the third most prevalent disease and the second most common cancer in terms of fatality. People diagnosed with colorectal cancer in the early stages have a five-year survival rate of roughly 95%, but people identified with the disease in the later stages have a survival rate of approximately 12%.

Infection and insufficient osseointegration are the primary factors leading to the failure of titanium-based implants. Surface coating modifications that combine both antibacterial and osteogenic properties are commonly employed strategies. However, the challenge of achieving rapid antibacterial action and consistent osteogenesis with these coatings remains unresolved.

Proper identification and management of post-kala-azar dermal leishmaniasis (PKDL) and canine leishmaniasis (CanL) cases are among the prerequisites to the effective control of visceral leishmaniasis worldwide. Unlike PKDL, CanL still awaits effective improvement because of its cryptic nature, absence of parasites in lesions or lymph nodes and not complete sensitivity of some diagnostic tools in use. Because of the need for certain skills and equipment, both the liquid direct agglutination test and freeze-dried direct agglutination test (FD-DAT) versions are, in comparison with the indirect immunofluorescence antibody test (IFAT) or enzyme-linked immunosorbent assay (ELISA), practical and feasible diagnostic alternatives.

Article Synopsis
  • The review investigates the establishment of diagnostic reference levels (DRLs) for pediatric brain CT scans in Saudi Arabia and compares them with data from nine other countries.
  • The findings reveal significant differences in CT doses, particularly concerning age groups, with specific DRLs provided for Saudi children aged 0-5 years and 6-15 years.
  • The study highlights the need for age-specific DRLs to enhance radiation safety and recommends adopting global standards while acknowledging limitations like inconsistencies in age classifications and restricted literature access.

To assess the sources, levels, spatial distributions and exposure to human health, the concentration of heavy metals Pb, Cu, Mn, Zn, and Fe in the sand/sediment of the Parki Beach area of Anowara, Chattogram, Bangladesh are determined using Atomic Absorption Spectroscopy (AAS) for the first time. A total of 40 surface and subsurface sand and sediment samples were collected from 20 different sampling points along the 15 km long Parki Beach area, Bangladesh. Average concentrations of Pb, Cu, Mn, Zn and Fe in surface samples are 14.

Article Synopsis
  • The study investigates the effectiveness of abdominal ultrasounds in diagnosing appendicitis, noting that a significant number (45-82%) of ultrasounds yield inconclusive results, requiring further testing like CT scans.
  • Researchers analyzed health records of patients with right lower quadrant pain and indeterminate ultrasounds, focusing on determining factors that could help rule out appendicitis without needing a CT scan.
  • The findings indicate that a high neutrophil count and certain ultrasound signs correlate with appendicitis; however, not having these indicators allows for a reliable rule-out strategy, with a negative predictive value of 97%.

Despite a bicentennial history, the interest in polyiodides and related systems still flourishes. The chemical puzzle provided by the intricate nature of chemical bonding in these polyanions remains challenging these days. The advent of the halogen bond and the spreading interest in supramolecular interactions of halogen-based systems promoted further recent interest.

Introduction: Heart failure (HF) is a complex and heterogeneous syndrome resulting from any diastolic or systolic dysfunction of the cardiac muscle. In addition to comorbid conditions, pressure overload, and myocardial ischemia are associated with cardiac remodeling which manifests as extracellular matrix (ECM) perturbations, impaired cellular responses, and subsequent ventricular dysfunction.

Areas Covered: The current review discusses the main aspects of the cyclic guanosine monophosphate (cGMP)-protein kinase G (PKG) pathway (cGMP-PKG) pathway modulators and highlights the promising outcomes of its novel pharmacological boosters.

Background: The Whipple procedure for pancreatic adenocarcinoma frequently is referred to surgeons at high-volume centers, which requires that patients travel long distances, potentially impacting patient outcomes. Furthermore, patients with pancreatic cancer from underserved areas often have poor outcomes. There are limited data on Whipple outcomes on the basis of both socioeconomic and distance traveled.

  • People with HIV (PWH) have a higher risk of cardiovascular disease (CVD) compared to those without HIV, and the study aimed to evaluate their adherence to CVD medications and factors influencing non-adherence.
  • Conducted at the University Hospitals of Leicester NHS Trust, this study analyzed data from 162 PWH, with findings indicating that about one-third of patients did not have prescribed medications detected in their urine, particularly highlighting issues with lipid-lowering agents.
  • The analysis showed that a higher number of prescribed medications correlated with non-adherence, emphasizing the need for improved strategies to enhance medication compliance among PWH for better health outcomes.

The prevalence of Metabolic-associated fatty liver disease (MAFLD) has been steadily increasing worldwide, paralleling the global epidemic of obesity and diabetes. It is estimated that approximately one-quarter of the global population is affected by MAFLD. Despite its high prevalence, MAFLD often goes undiagnosed due to the lack of specific symptoms in its early stages.

One of the most well-liked energizing drinks is now tea, which is primarily used in Malaysia. The natural radioactivity in the associated soils where tea plants are cultivated plays a major role in determining the presence of radionuclides in tea leaves. The present study assesses the transfer of radionuclides from soil-to-tea leaves and then estimates the committed effective doses through tea consumption.

Hypertension is the leading modifiable risk factor for cardiovascular disease, but less than 50% have their blood pressure controlled. A possible avenue to support hypertension management is a holistic approach, using non-pharmacological interventions. Since hypertension is mediated in part by dysregulation of the autonomic nervous system (ANS), biofeedback may help improve hypertension management by targeted self-regulation and self-awareness of parameters that regulate the ANS.
