Objectives: Predicting longer term response to biological therapy for small bowel Crohn's disease (SBCD) is an unmet clinical need. Diffusion-weighted MR imaging (DWI) may indicate disease activity, but its predictive ability, if any, is unknown. We investigated the prognostic value of DWI for one year response or remission (RoR) in SBCD patients commencing biologic therapy, including incremental value over C-reactive protein (CRP) and faecal calprotectin (FC).

Antimicrobial resistance can arise in the natural environment via prolonged exposure to the effluent released by manufacturing facilities. In addition to antibiotics, pharmaceutical plants also produce non-antibiotic pharmaceuticals, both the active ingredients and other components of the formulations. The effect of these on the surrounding microbial communities is less clear.

Microbial pathogens have developed resistance mechanisms to almost every antibiotic available. There is a need to synthesize or screen new natural compounds to combat the development of drug-resistant pathogens. One of the commonly used methods to evaluate the antimicrobial activity of two or more antibiotics involves a checkerboard assay, which is cumbersome, time-consuming, and expensive.

Background: Criticism of mainstream approaches to child labour is widespread and well-established. The Child Labour Action Research in South and Southeast Asia (CLARISSA) Cash Plus pilot sought to address these critiques through an innovative programme that prioritised the development of household resilience and well-being, and through increasing household capacity to make alternative choices around children's work.

Research: Funded by the UK's Foreign, Commonwealth and Development Office, this pilot delivered unconditional cash transfers (UCTs) and needs-based case management and community mobilising across an entire slum neighbourhood in Dhaka, Bangladesh.

Article Synopsis
  • All-solid-state lithium-ion batteries (ASSLBs) are poised to enhance the performance and safety of next-generation electronics, especially electric vehicles, by utilizing solid electrolytes with high ionic conductivity.
  • Researchers have substituted the B-site of LiLaTiO (LLTO) with Ga to create Ga-doped LLTO solid electrolytes, leading to structural improvements, enhanced ionic conductivity, and better electrochemical stability through a solid-state reaction method.
  • The results show that Ga-doped LLTO exhibits a significantly increased ionic conductivity of 4.15 × 10 S cm in LiLaTiGaO (with 3% Ga), making it a promising candidate for future ASSLB applications due to its stable operating voltage range.

Microplastics (MPs), less than 5 mm in length, have become a major environmental issue due to their hazardous physical and chemical properties. The research investigated 54 sediment samples collected from three different zones of the beaches, namely the wrack line, beach face, and swash zone. This study aims to enumerate the number and polymeric variety of microplastics found in beach sediments from coastal islands of Bangladesh, including Sandwip, Kutubdia, and Saint Martin's Island in the northeastern Bay of Bengal.

This study aims to fill the gap in our understanding of the distribution and ecological risk of oil and grease (OG) and toxic heavy metals in the surface water of the Naf River, a major transportation route connecting Teknaf to Saint Martin's Island in Bangladesh. Altogether, 6 sampling stations in this river were assessed for OG and heavy metal pollution, revealing the presence of both at each station. The OG concentration is found ranging from 3.

Article Synopsis
  • - The study investigates the health of the aquatic ecosystem in the Sundarbans, the largest mangrove forest globally, by analyzing key water quality indicators including Chlorophyll-a, Total Suspended Matter, and Colored Dissolved Organic Matter using both remote sensing and on-site data collection.
  • - Results indicate significant seasonal fluctuations, with higher levels of Chlorophyll-a and Total Suspended Matter observed during the post-monsoon season, attributed to various environmental factors.
  • - The findings emphasize the importance of ongoing monitoring to identify and address anthropogenic threats to the ecosystem, providing a foundational understanding necessary for conservation efforts.

Background: The dopamine transporter striatal binding ratio (DAT SBR) has been used as an outcome measure in Parkinson's disease (PD) trials of potential disease-modifying therapies; however, both patient characteristics and analysis approach potentially complicate its interpretation.

Objective: The aim was to explore how well DAT SBR reflects PD motor severity across different striatal subregions and the relationship to disease duration, and side of onset.

Methods: DAT SBR for the anterior and posterior putamen and caudate in both hemispheres was obtained using validated automated quantitative software on baseline scans of 132 patients recruited for the Exenatide PD2 and PD3 trials.

Cardiometabolic syndrome (CMS), type 2 diabetes mellitus (T2DM), and cardiovascular diseases are among the major altruists to the international liability of disease. The lifestyle and dietary changes attributable to economic growth have resulted in an epidemiological transition towards non-communicable diseases (NCDs) as the leading causes of death. Low- and middle-income countries (LMICs) bear a more substantial disease burden due to limited healthcare sector capacities to address the rapidly growing number of chronic disease patients.

Objectives: Drug-drug interactions (DDIs) are a common problem in pharmacotherapy, particularly in situations where multiple disorders must be treated at the same time. We conducted a drug use survey in the general medicine outpatient department of a tertiary care hospital with the objective of assessing the potential for DDI in individual prescriptions for adult patients.

Materials And Methods: Drugs prescribed in the current physician-patient encounter were considered in conjunction with medicines already being received by the patient as well as those discontinued in the past 1 month.

There has been a significant increase in the consumption of cannabis for both recreational and medicinal purposes in recent years, and its use can have long-term consequences on cognitive functions, including memory. Here, we review the immediate and long-term effects of cannabis and its derivatives on glutamatergic neurotransmission, with a focus on both the presynaptic and postsynaptic alterations. Several factors can influence cannabinoid-mediated changes in glutamatergic neurotransmission, including dosage, sex, age, and frequency of use.

Constipation suffered by children is a global public health problem. Functional constipation (FC) brings about deteriorating effects in the children's lives who suffer from it. The risk factors for the development of constipation include the consumption of a diet low in fiber and high in calories (such as the consumption of fast food), a sedentary lifestyle with a lack of exercise, a family history of constipation, and emotional and psychological stress endured by children in their families.

  • Patients with end-stage ankle osteoarthritis face limited mobility and have two main surgical options: total ankle replacement (TAR) and ankle fusion (AF).
  • The study aimed to compare the costs and quality of life improvements associated with TAR versus AF over 52 weeks and over the patients' lifetime, using a cost-utility analysis on 282 participants from a trial.
  • Results showed TAR was more expensive than AF at 52 weeks, with a cost-effectiveness ratio indicating TAR isn't cost-effective in the short term; however, long-term modeling suggested it could become cost-effective, with a 69% likelihood if using a threshold of £20,000 per quality-adjusted life-year gained.

Introduction Estimating ovarian reserve has been the cornerstone of designing treatment plans for female infertility over the last few years. The most reliable biomarker for assessing female fertility is the antral follicle count (AFC). Also, the anti-müllerian hormone (AMH) is a sensitive test for predicting ovarian reserve and is precisely associated with AFC value.
