#1
REVIEW
Sarah Duggan, Wayne Cummins, Orla O' Donovan, Helen Hughes, Eleanor Owens
Mucoadhesion is the process of binding a material to the mucosal layer of the body. Utilising both natural and synthetic polymers, mucoadhesive drug delivery is a method of controlled drug release which allows for intimate contact between the polymer and a target tissue. It has the potential to increase bioavailability, decrease potential side effects and offer protection to more sensitive drugs such as proteins and peptide based drugs. The thiolation of polymers has, in the last number of years, come to the fore of mucoadhesive drug delivery, markedly improving mucoadhesion due to the introduction of free thiol groups onto the polymer backbone while also offering a more cohesive polymeric matrix for the slower and more controlled release of drug...

Emily Reeve, Wade Thompson, Barbara Farrell
Deprescribing can be defined as the process of withdrawal or dose reduction of medications which are considered inappropriate in an individual. The aim of this narrative review is to provide an overview of "deprescribing"; firstly discussing the potential benefits and harms followed by the barriers to and enablers of deprescribing. We also provide practical recommendations to recognise opportunities and strategies for deprescribing in practice. Studies focused on minimizing polypharmacy indicate that deprescribing may be associated with potential benefits including resolution of adverse drug reactions, improved quality of life and medication adherence and a reduction in drug costs...

BACKGROUND: Rectal infection with Chlamydia trachomatis is one of the most common bacterial sexually transmissible infections among men who have sex with men (MSM) with diagnosis rates continuing to rise. Current treatment guidelines recommend either azithromycin 1 g single dose or doxycycline 100 mg twice daily for 7 days. However, there are increasing concerns about treatment failure with azithromycin. We are conducting the first randomised controlled trial (RCT) to compare treatment efficacy of azithromycin versus doxycycline for the treatment of rectal chlamydia in MSM...

REVIEW
Mohammad A Chowdhury
The metal-organic-frameworks (MOFs) materials are increasingly gaining attraction to utilise into biomedical applications. MOFs are playing a major role to harnessing dual or multiple modalities in therapeutics and diagnostics. MOFs are mostly devised for particular biomedical application by post-synthetic functionalization or modification using variety of polymers, bio-ligands, and silica coating processes. This articles presents a brief overview of two particular areas of biomedical applications where a broad range of MOFs have been used: 1) variety of drug delivery including intracellular drug delivery systems using the MOFs-based carriers; and, 2) development of MOFs-based contrast agents for magnetic resonance image enhancement...

The vaginal route is increasingly being considered for both local and systemic delivery of drugs, especially those unsuitable for oral administration. One of the opportunities offered by this route but yet to be fully utilised is the administration of microbicides. Microbicides have an unprecedented potential for mitigating the global burden from HIV infection as heterosexual contact accounts for most of the new infections occurring in sub-Saharan Africa, the region with the highest prevalent rates. Decades of efforts and massive investment of resources into developing an ideal microbicide have resulted in disappointing outcomes, as attested by several clinical trials assessing the suitability of those formulated so far...

INTRODUCTION: β-Tubulin is an important target for the binding of anti-cancer drugs, in particular, paclitaxel (taxol), vinblastine and epothilone. However, mutations in β-tubulin structure give resistance to chemotherapeutic agents. Notably, mutations at R306C, F270 V, L217R, L228F, A185T and A248V positions in β-tubulin give high resistance for paclitaxel binding. OBJECTIVE: To discover novel inhibitors of β-tubulin from natural sources, particularly alkaloids, using a virtual screening approach...

Tuberculosis (TB), although a curable disease, has remained one of the most difficult infections to treat. Mycobacterium tuberculosis (M. tuberculosis.) infects 10 million people worldwide and kills 1.5 million people each year. Reactivation of latent infection is the major cause of TB. Cholesterol is a critical carbon source during latent infection. Catabolism of cholesterol contributes to the pool of propionyl-CoA, a precursor that is incorporated into lipid virulence factors. The M. tuberculosis genome contains a large regulon of cholesterol catabolic genes suggesting that the microorganism can utilise host sterol for infection and persistence...

Spheroids have been shown to recapitulate the tumour in vivo with properties such as the tumour microenvironment, concentration gradients, and tumour phenotype. As such, it can serve as a platform for determining the growth and invasion behaviour pattern of the cancer cells as well as be utilised for drug sensitivity assays; capable of exhibiting results that are closer to what is observed in vivo compared to two-dimensional (2D) cell culture assays. This study focused on establishing a three-dimensional (3D) cell culture model using the Nasopharyngeal Carcinoma (NPC) cell line, HK1 and analysing its growth and invasion phenotypes...

Alcohol and Other Drug (AOD) education amongst hospital staff is often inadequate. This leads to suboptimal care of patients and is a missed opportunity for early identification and treatment. This integrative review evaluates the core features of current education for hospital-based doctors and nurses in AOD, including country of origin, content, duration, and pedagogy. The majority of included studies were conducted in the USA (72%), target alcohol rather than AOD in general (72%), adopted a purely medical model of treatment (94%), and utilised a Screening, Brief Intervention, and Referral to Treatment (SBIRT) model (94%)...
