Revolutionizing Antibacterial Strategies: Lipid Nanoparticles as Game-Changers in Combatting Multi-Drug-Resistant Infections.

To overcome the limits of traditional antibiotic medications, novel approaches are needed to combat the growing global epidemic of Multidrug-resistant (MDR) infections. As drug-resistant bacteria develop, the importance of innovative antimicrobial methods is underscored by antibiotic abuse and misuse. The global threat of MDR microorganisms is increasing, which calls for a coordinated global response. Lipid Nanoparticles (LNPs) possess several characteristics that make them attractive choices for managing multidrug resistant (MDR) infections, as well as potential delivery systems for antimicrobial agents. Thus, LNPs improve drug solubility, stability, and targeted delivery, thereby mitigating the drawbacks of conventional antibiotic therapy. Several characteristics of LNPs, which stop MDR bacteria from developing resistance mechanisms, serve as guidelines for precision medicine. It presents a powerful approach for combating the growing concern of MDR bacteria by increasing Anti-Microbial Peptides (AMPs) bioavailability and targeting distribution to bacterial cells. LNPs have the potential to redefine antibacterial treatments for MDR illnesses in the context of this study. Further, it discusses LNP use in larger applications, such as fighting Anti-Microbial Resistance (AMR) and MDR. A complete understanding of the unique features, many uses, and importance of collaborative efforts to overcome the global challenge of antibiotic resistance are also conveyed in the study.

Exploring Medical Student Attitudes Regarding Inter-university Learning: A Pilot Study.

Introduction The United Kingdom needs to educate more medical students to meet workforce demands. With static numbers of clinical teachers available, novel and efficient approaches are required to prepare students for real-life work where doctors routinely work with colleagues from different medical schools. This innovative project was designed to investigate student attitudes towards inter-university learning (IUL), whereby two medical students from different universities learn together. Materials and methods Thirteen students at Great Western Hospital, Swindon, England, volunteered and were randomly paired with a student from another university. Pairs completed a 20-minute simulated clinical scenario and observed three others. Students completed pre- and post-session questionnaires adapted from the Readiness for Inter-Professional Learning scale. Seven students took part in semi-structured interviews which underwent thematic analysis. Results Quantitative analysis of post-session questionnaires demonstrated a positive response to IUL. Thematic analysis generated six themes: impact on learning, impact on career, working together, recognising differences, practical considerations, and psychosocial perspectives. Discussion Students enjoyed the social learning opportunity to practise team-working, communication, and role delegation with unknown peers whilst sharing different clinical approaches. Differences in course structure meant students displayed varying strengths, although unexpected findings centred around pre-conceptions of both universities and social comparison behaviours. Conclusion IUL's strength was deemed to be in non-technical skill development to prepare for real-life work, ultimately enhancing patient safety. Practicalities to consider include session design and psychological safety. IUL provides a novel solution to efficiently educate future healthcare professionals and further work to explore its benefits on a wider scale is suggested.

Controversies and Advances in the Personalized Surgical Treatment of Cervical Cancer.

Cervical cancer represents a global health issue as it is mostly encountered in women of reproductive age, while at the same time, survival outcomes seem to have remained constant during the last two decades. The need to implement fertility-sparing strategies as well as to decrease the morbidity that accompanies radical treatment has been extensively studied. During the last decade, several randomized clinical trials have been released, resulting in significant advances in the surgical treatment of early-stage disease. At the same time, evidence about the surgical treatment of advanced-stage disease as well as recurrent disease has gradually appeared and seems to be promising, thus leading the point forward towards personalized medicine that will remove the surgical barriers that seem concrete in our era. Nevertheless, the discrepancies in perioperative morbidity and survival outcomes that were observed among published studies raise several questions. In the present article, we chose to review the gray fields in the surgical treatment of early-stage and advanced-stage cervical cancer. Studies that are based on strong evidence that support current clinical practice are compared to smaller cohorts that present novel data that may form the basis for future research, and issues that remain poorly explored are discussed in an effort to help establish a consensus for future research development.

Novel Gene Therapy Approaches for Targeting Neurodegenerative Disorders: Focusing on Delivering Neurotrophic Genes.

Neurodegenerative illnesses (NDDs) like Alzheimer's, Parkinson's, amyotrophic lateral sclerosis, spinal muscular atrophy, and Huntington's disease have demonstrated considerable potential for gene therapy as a viable therapeutic intervention. NDDs are marked by the decline of neurons, resulting in changes in both behavior and pathology within the body. Strikingly, only symptomatic management is available without a cure for the NDDs. There is an unmet need for a permanent therapeutic approach. Many studies have been going on to target the newer therapeutic molecular targets for NDDs including gene-based therapy. Gene therapy has the potential to provide therapeutic benefits to a large number of patients with NDDs by offering mechanisms including neuroprotection, neuro-restoration, and rectification of pathogenic pathways. Gene therapy is a medical approach that aims to modify the biological characteristics of living cells by controlling the expression of specific genes in certain neurological disorders. Despite being the most complex and well-protected organ in the human body, there is clinical evidence to show that it is possible to specifically target the central nervous system (CNS). This provides hope for the prospective application of gene therapy in treating NDDs in the future. There are several advanced techniques available for using viral or non-viral vectors to deliver the therapeutic gene to the afflicted region. Neurotrophic factors (NTF) in the brain are crucial for the development, differentiation, and survival of neurons in the CNS, making them important in the context of various neurological illnesses. Gene delivery of NTF has the potential to be used as a therapeutic approach for the treatment of neurological problems in the brain. This review primarily focuses on the methodologies employed for delivering the genes of different NTFs to treat neurological disorders. These techniques are currently being explored as a viable therapeutic approach for neurodegenerative diseases. The article exclusively addresses gene delivery approaches and does not cover additional therapy strategies for NDDs. Gene therapy offers a promising alternative treatment for NDDs by stimulating neuronal growth instead of solely relying on symptom relief from drugs and their associated adverse effects. It can serve as a long-lasting and advantageous treatment choice for the management of NDDs. The likelihood of developing NDDs increases with age as a result of neuronal degradation in the brain. Gene therapy is an optimal approach for promoting neuronal growth through the introduction of nerve growth factor genes.

Bridging the gap in rheumatoid arthritis treatment with hyaluronic acid-based drug delivery approaches.

Rheumatoid Arthritis (RA) is a chronic, inflammatory, auto-immune disease that is majorly associated with the degradation of the synovial linings of the joints. It is a progressive disease that reduces the life span in affected individuals. Nanoparticles involving hyaluronic acid (HA) have gained the limelight for designing target-specific and more effective drug delivery options for RA. HA is found abundantly in the synovial fluid and acts as a natural ligand for the CD44 receptors. The targeted delivery approach using CD44 as the target can help in minimizing off-target drug distribution. These HA-based surface-decorated nanocarriers, hydrogels, and MNs are cutting-edge strategies that promise tailored delivery, fewer side effects, and more patient adherence to address the common issues associated with RA therapy. Considering the above facts, this review attempts to discuss the role of HA in making more effective formulations for therapeutic delivery in treating RA. Additionally, it provides a comprehensive overview of the potential advancements, mainly in treating RA by HA-based topical, transdermal, and parenteral drug delivery systems, with relevant case studies. The existing difficulties and potential paths for future research on HA-based non-conventional formulations for the management of RA are also discussed.

Exploring Potential of Nano-formulations in the Treatment of Alzheimer's Disease through Nasal Route.

OBJECTIVE: Alzheimer's disease, a progressive neurodegenerative disorder, severely impacts cognitive function and daily living. The current treatment provides only symptomatic relief, and thus, disease-modifying therapies targeting underlying causes are needed. Although several potential therapies are in various stages of clinical trials, bringing a new Alzheimer's drug to market remains challenging. Hence, researchers are also exploring monoclonal antibodies, tau protein inhibitors, and anti-inflammatory drugs as treatment options. Conventionally designed dosage forms come with limitations like poor absorption, first-pass metabolism, and low bioavailability. They also cause systemic adverse effects because these designed systems do not provide target- specific drug delivery. Thus, in this review, the authors highlighted the current advancements in the development of intranasal nanoformulations for the treatment of Alzheimer's disease. This strategy of delivering anti-Alzheimer drugs through the nasal route may help to target the drug exactly to the brain, achieve rapid onset of action, avoid first-pass metabolism, and reduce the side effects and dose required for administration. CONCLUSION: Delivering drugs to the brain through the nasal route for treating Alzheimer's disease is crucial due to the limited efficacy of existing treatments and the profound impact of the disease on patients and their families. Thus, by exploring innovative approaches such as nose-to-brain drug delivery, it is possible to improve the quality of life for individuals living with Alzheimer's and alleviate its societal burden.

Diagnosis of extra pulmonary tuberculosis: An update on novel diagnostic approaches.

Tuberculosis (TB) remains a major global public health problem worldwide. Though Pulmonary TB (PTB) is mostly discussed, one in five cases of TB present are extrapulmonary TB (EPTB) that manifests conspicuous diagnostic and management challenges with respect to the site of infection. The diagnosis of EPTB is often delayed or even missed due to insidious clinical presentation, pauci-bacillary nature of the disease, and lack of laboratory facilities in the resource limited settings. Culture, the classical gold standard for the diagnosis of tuberculosis, suffers from increased technical and logistical constraints in EPTB cases. Other than culture, several other tests are available but their feasibility and effciacy for the detection of EPTB is still the matter of interest. We need more specific and precise test/s for the various forms of EPTB diagnosis which can easily be applied in the routine TB control program is required. A test that can contribute remarkably towards improving EPTB case detection reducing the morbidity and mortality is the utmost requirement. In this review we described the scenario of molecular and other noval methods available for laboratory diagnosis of EPTB, and also discussed the challenges linked with each diagnostic method. This review will make the readers aware of new emerging diagnostic techniques in the field of EPTB diagnosis. They can make an informed decision to choose the appropriate one according to the test availability, their clinical settings and financial considerations.

Emerging strategies and therapeutic innovations for combating drug resistance in Staphylococcus aureus strains: A comprehensive review.

In recent years, antibiotic therapy has encountered significant challenges due to the rapid emergence of multidrug resistance among bacteria responsible for life-threatening illnesses, creating uncertainty about the future management of infectious diseases. The escalation of antimicrobial resistance in the post-COVID era compared to the pre-COVID era has raised global concern. The prevalence of nosocomial-related infections, especially outbreaks of drug-resistant strains of Staphylococcus aureus, have been reported worldwide, with India being a notable hotspot for such occurrences. Various virulence factors and mutations characterize nosocomial infections involving S. aureus.

Despite prompt diagnosis, the elimination of drug-resistant infections remains unattainable in the absence of effective alternative therapies. Researchers are exploring various alternative therapeutic approaches, including phage therapy, antimicrobial peptides, photodynamic therapy, vaccines, host-directed therapies, and more. The proposed review mainly focuses on the resistance journey of S. aureus over the past decade, detailing its resistance mechanisms, prevalence in the subcontinent, innovations in rapid diagnosis of the drug-resistant strains, including the applicants of NGS and ML application along with QC, it helps to design alternative novel therapeutics approaches against S. aureus infection.

Pseudomonas aeruginosa: Infections and novel approaches to treatment "Knowing the enemy" the threat of Pseudomonas aeruginosa and exploring novel approaches to treatment.

Pseudomonas aeruginosa is an aerobic Gram-negative rod-shaped bacterium with a comparatively large genome and an impressive genetic capability allowing it to grow in a variety of environments and tolerate a wide range of physical conditions. This biological flexibility enables the P. aeruginosa to cause a broad range of infections in patients with serious underlying medical conditions, and to be a principal cause of health care associated infection worldwide. The clinical manifestations of P. aeruginosa include mostly health care associated infections and community-acquired infections. P. aeruginosa possesses an array of virulence factors that counteract host defence mechanisms. It can directly damage host tissue while utilizing high levels of intrinsic and acquired antimicrobial resistance mechanisms to counter most classes of antibiotics. P. aeruginosa co-regulates multiple resistance mechanisms by perpetually moving targets poses a significant therapeutic challenge. Thus, there is an urgent need for novel approaches in the development of anti-Pseudomonas agents. Here we review the principal infections caused by P. aeruginosa and we discuss novel therapeutic options to tackle antibiotic resistance and treatment of P. aeruginosa infections that may be further developed for clinical practice.

Filling the data gaps: Transferring models from data-rich to data-poor deep-sea areas to support spatial management.

Spatial management of the deep sea is challenging due to limited available data on the distribution of species and habitats to support decision making. In the well-studied North Atlantic, predictive models of species distribution and habitat suitability have been used to fill data gaps and support sustainable management. In the South Atlantic and other poorly studied regions, this is not possible due to a massive lack of data. In this study, we investigated whether models constructed in data-rich areas can be used to inform data-poor regions (with otherwise similar environmental conditions). We used a novel model transfer approach to identify to what extent a habitat suitability model for Desmophyllum pertusum reef, built in a data-rich basin (North Atlantic), could be transferred usefully to a data-poor basin (South Atlantic). The transferred model was built using the Maximum Entropy algorithm and constructed with 227 presence and 3064 pseudo-absence points, and 200 m resolution environmental grids. Performance in the transferred region was validated using an independent dataset of D. pertusum presences and absences, with assessments made using both threshold-dependent and -independent metrics. We found that a model for D. pertusum reef fitted to North Atlantic data transferred reasonably well to the South Atlantic basin, with an area under the curve of 0.70. Suitable habitat for D. pertusum reef was predicted on 20 of the assessed 27 features including seamounts. Nationally managed Marine Protected Areas provide significant protection for D. pertusum reef habitat in the region, affording full protection from bottom trawling to 14 of the 20 suitable features. In areas beyond national jurisdiction (ABNJ), we found four seamounts that provided suitable habitat for D. pertusum reef to be at least partially protected from bottom trawling, whilst two did not fall within fisheries closures. There are factors to consider when developing models for transfer including data resolution and predictor type. Nevertheless, the promising results of this application demonstrate that model transfer approaches stand to provide significant contributions to spatial planning processes through provision of new, best available data. This is particularly true for ABNJ and areas that have previously undergone little scientific exploration such as the global south.

Unmet needs in clinical trials in CKD: questions we have not answered and answers we have not questioned.

Many advances have been made in the field of nephrology over the last decade. These include an increasing focus on patient-centred involvement in trials, exploration of innovative trial designs and methodology, the growth of personalized medicine and, most importantly, novel therapeutic agents that are disease-modifying for large groups of patients with and without diabetes and chronic kidney disease. Despite this progress, many questions remain unanswered and we have not critically evaluated some of our assumptions, practices and guidelines despite emerging evidence to challenge current paradigms and discrepant patient-preferred outcomes. How best to implement best practices, diagnose various conditions, examine better diagnostic tools, treat laboratory values versus patients and understand prediction equations in the clinical context remain unanswered. As we enter a new era in nephrology, there are extraordinary opportunities to change the culture and care. Rigorous research paradigms enabling both the generation and the use of new information should be explored. We identify here some key areas of interest and suggest renewed efforts to describe and address these gaps so that we can develop, design and execute trials of importance to all.

Codelivery of Phytochemicals with Conventional Anticancer Drugs in Form of Nanocarriers.

Anticancer drugs in monotherapy are ineffective to treat various kinds of cancer due to the heterogeneous nature of cancer. Moreover, available anticancer drugs possessed various hurdles, such as drug resistance, insensitivity of cancer cells to drugs, adverse effects and patient inconveniences. Hence, plant-based phytochemicals could be a better substitute for conventional chemotherapy for treatment of cancer due to various properties: lesser adverse effects, action via multiple pathways, economical, etc. Various preclinical studies have demonstrated that a combination of phytochemicals with conventional anticancer drugs is more efficacious than phytochemicals individually to treat cancer because plant-derived compounds have lower anticancer efficacy than conventional anticancer drugs. Moreover, phytochemicals suffer from poor aqueous solubility and reduced bioavailability, which must be resolved for efficacious treatment of cancer. Therefore, nanotechnology-based novel carriers are employed for codelivery of phytochemicals and conventional anticancer drugs for better treatment of cancer. These novel carriers include nanoemulsion, nanosuspension, nanostructured lipid carriers, solid lipid nanoparticles, polymeric nanoparticles, polymeric micelles, dendrimers, metallic nanoparticles, carbon nanotubes that provide various benefits of improved solubility, reduced adverse effects, higher efficacy, reduced dose, improved dosing frequency, reduced drug resistance, improved bioavailability and higher patient compliance. This review summarizes various phytochemicals employed in treatment of cancer, combination therapy of phytochemicals with anticancer drugs and various nanotechnology-based carriers to deliver the combination therapy in treatment of cancer.

Resistance to prostate cancer treatments.

A review of the current treatment options for prostate cancer and the formation of resistance to these regimens has been compiled including primary, acquired, and cross-resistance. The diversification of the pathways involved and the escape routes the tumor is utilizing have been addressed. Whereas early stages of tumor can be cured, there is no treatment available after a point of no return has been reached, leaving palliative treatment as the only option. The major reasons for this outcome are the heterogeneity of tumors, both inter- and intra-individually and the nearly endless number of escape routes, which the tumor can select to overcome the effects of treatment. This means that more focus should be applied to the individualization of both diagnosis and therapy of prostate cancer. In addition to current treatment options, novel drugs and ongoing clinical trials have been addressed in this review.
