An 8-Year-Old Boy With Hepatic Embryonal Sarcoma Managed With Surgical Resection.

The extent of hepatic tumors in childhood differs from that found in older age groups. Some of these tumors are believed to be quite rare like undifferentiated embryonal sarcoma of the liver (UESL). The challenge in diagnosis arises from the nonspecific clinical, biochemical, and radiological features, with definitive diagnosis requiring pathological confirmation following surgical excision.

Social Determinants of Health Impacting Access to Renal Dialysis for Racial/Ethnic Minorities.

Although widespread, the burden of disease presented by chronic kidney disease (CKD) is not equally distributed among all demographics. Examining the social determinants of health (SDOH) that relate to barriers to renal dialysis care in CKD can help to prevent future disparities. There has not been a study addressing the social factors that create barriers to care for ethnic minority patients with CKD.

GPs' and pharmacists' views of integrating pharmacists into general practices: a qualitative study.

Background: Practice-based pharmacists (PBPs) have been introduced into general practice across the UK to relieve some of the pressures within primary care. However, there is little existing UK literature that has explored healthcare professionals' (HCPs') views about PBP integration and how this role has evolved.

Aim: To explore the views and experiences of GPs, PBPs, and community pharmacists (CPs) about PBPs' integration into general practice and their impact on primary healthcare delivery.

A 20-Year-Old Gossypiboma Causing Small Bowel Obstruction.

Retained foreign bodies including gossypiboma could be silent for years. However, in some cases, it can lead to major complications. Gossypiboma is not frequently reported for multiple reasons, including nonspecific presentation clinically and radiologically, and ethical issues.

Development of a core set of clinical skills for pharmacist prescribers working in general practice: A Delphi study.

Background: With increasing numbers of pharmacists working in general practices and undertaking patient-facing roles, it has been recognised that they must have the necessary clinical skills. However, previous studies have highlighted that practice-based pharmacists (PBPs) do not feel confident regarding their clinical skills, and it is unclear what skills are needed.

Objective: To develop a core set of clinical skills (CSs) required for pharmacists who intend to practise as independent prescribers working in general practice/family medicine.

Immobilization of glucose oxidase on bioinspired polyphenol coatings as a high-throughput glucose assay platform.

Glucose oxidase (GOx) is an enzyme with important industrial and biochemical applications, particularly in glucose detection. Here we leveraged the oxidative self-polymerization phenomenon of simple polyphenols (pyrogallol or catechol) in the presence of polyethylenimine (PEI) to form adhesive coatings that enabled GOx immobilization on conventional multi-well plates. Immobilization was verified and optimized by directly measuring GOx activity inside the coated wells.

General practitioners' experiences with, views of, and attitudes towards, general practice-based pharmacists: a cross-sectional survey.

Background: There is limited United Kingdom (UK) literature on general practice-based pharmacists' (PBPs') role evolution and few studies have explored general practitioners' (GPs') experiences on pharmacist integration into general practice. Therefore, this study aimed to investigate GPs' experiences with, views of, and attitudes towards PBPs in Northern Ireland (NI).

Methods: A paper-based self-administered questionnaire comprising four sections was mailed in 2019 to 329 general practices across NI and was completed by one GP in every practice who had most contact with the PBP.

Peritoneal Tuberculosis in a Young Healthy Male Resembling Intra-Abdominal Malignancy.

Intra-peritoneal tuberculosis is a rare disease, accounting for 1-2% of all tuberculosis cases. The absence of characteristic clinical picture of intra-peritoneal tuberculosis makes the diagnosis rarely easy for clinicians as it mimics malignancy. We present a case of a young male patient who presented with peritoneal tuberculosis, aiming to contribute to a better understanding of peritoneal tuberculosis in the literature.

Future healthcare providers and professionalism on social media: a cross-sectional study.

Background: Nowadays, social media have become central in the daily lives of people, including healthcare professionals. Fears arise that the accelerated growth of these social platforms was not accompanied by the appropriate training of the healthcare students and workers on the professional use of social media. This study primarily aimed to assess the awareness of the healthcare students at Beirut Arab University, Lebanon on the professional standards of social media.

A systematic review of general practice-based pharmacists' services to optimize medicines management in older people with multimorbidity and polypharmacy.

Background: Few studies have evaluated roles of general practice-based pharmacists (PBPs), particularly in optimizing medicines management for older people with both multimorbidity and polypharmacy.

Objective: To explore the types and effectiveness of services provided by PBPs, either alone or in collaboration with other primary health care professionals, that sought to optimize medicines management for older people with multimorbidity and polypharmacy.

Methods: Eight electronic databases and three trial registries were searched for studies published in English until April 2020.

Development of a Thymoquinone Polymeric Anticancer Nanomedicine through Optimization of Polymer Molecular Weight and Nanoparticle Architecture.

Thymoquinone (TQ) is a water-insoluble natural compound isolated from that has demonstrated promising chemotherapeutic activity. The purpose of this study was to develop a polymeric nanoscale formulation for TQ to circumvent its delivery challenges. TQ-encapsulated nanoparticles (NPs) were fabricated using methoxy poly(ethylene glycol)--poly(ε-caprolactone) (mPEG-PCL) copolymers by the nanoprecipitation technique.

Bioinspired Polymerization of Quercetin to Produce a Curcumin-Loaded Nanomedicine with Potent Cytotoxicity and Cancer-Targeting Potential in Vivo.

Nanomedicine has had a profound impact on the treatment of many diseases, especially cancer. However, synthesis of multifunctional nanoscale drug carriers often requires multistep coupling and purification reactions, which can pose major scale-up challenges. Here, we leveraged bioinspired oxidation-triggered polymerization of catechols to synthesize nanoparticles (NPs) from the plant polyphenol quercetin (QCT) loaded with a hydrophobic anticancer drug, curcumin, and functionalized with poly(ethylene glycol) (PEG) for steric stabilization in one reaction step.

Nature-Inspired Polymerization of Quercetin to Produce Antioxidant Nanoparticles with Controlled Size and Skin Tone-Matching Colors.

Plant polyphenols have received considerable attention in recent years due to their ability to undergo oxidation-triggered self-polymerization, forming biocompatible versatile coatings and templated nanoparticles (NPs) that can be leveraged for a variety of biomedical applications. Here we show for the first time that untemplated NPs can be conveniently synthesized from the abundant plant polyphenol quercetin (QCT) simply by incubation with an oxidizing agent in a universal organic solvent, followed by self-assembly upon gradual addition of water. The process yielded NPs of around 180-200 nm in size with a range of colors that resembled light to medium-brown skin tones.

Outcomes of staged hepatectomies for liver malignancy.

Liver malignancies are the fifth most common cause of death worldwide. Surgical intervention with curative intent is the treatment of choice for liver tumors as it provides long-term survival. However, only 20% of patients with metastatic liver lesions can be managed by curative liver resection.

Adult Living Donor Liver Re-Transplant Following Late Pediatric Liver Transplant Failure: A Case Report.

BACKGROUND Re-transplant of a late failing living donor liver graft using another graft from another living donor is a rare occurrence and is associated with high mortality due to the complexity of the procedure. There are only a few such case series reported in the literature, mainly from South Asia and Japan, where living donor liver transplant is commonly performed, and there are no such reports from Western countries. CASE REPORT This is a case of living donor liver re-transplant for a 28-year-old recipient whose graft failed 14 years after his primary living donor transplant for primary sclerosing cholangitis.

Cholesterol-coated gold nanorods as an efficient nano-carrier for chemotherapeutic delivery and potential treatment of breast cancer: studies using the MCF-7 cell line.

Gold nanorods (GNRs) have a recognized role in treatment of cancers as efficient nanocarriers for chemotherapeutic drug delivery. In this study, GNRs modified with cholesterol-PEG were employed as a nanocarrier for a hydrophobic compound having a promising phosphatidylinositol 3-kinase (PI3Kα) inhibitory activity. The acquired nanocomplex was characterized by optical and infra-red (IR) absorption spectroscopies, in addition to hydrodynamic size and zeta potential.

Can we reduce ischemic cholangiopathy rates in donation after cardiac death liver transplantation after 10 years of practice? Canadian single-centre experience.

Background: Outcomes in liver transplantation with organs obtained via donation after cardiocirculatory death (DCD) have been suboptimal compared to donation after brain death, attributed mainly to the high incidence of ischemic cholangiopathy (IC). We evaluated the effect of a 10-year learning curve on IC rates among DCD liver graft recipients at a single centre.

Methods: We analyzed all DCD liver transplantation procedures from July 2006 to July 2016.

Optimizing associated liver partition and portal vein ligation for staged hepatectomy outcomes: Surgical experience or appropriate patient selection?

Background: Early reports of associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) outcomes have been suboptimal. The literature has confirmed that learning curves influence surgical outcomes. We have 54 months of continuous experience performing ALPPS with strict selection criteria.

Structure-Based Design: Synthesis, X-ray Crystallography, and Biological Evaluation of N-Substituted-4-Hydroxy-2-Quinolone-3-Carboxamides as Potential Cytotoxic Agents.

Background: Oncogenic potential of phosphatidylinositol 3-kinase (PI3Kα) has been highlighted as a therapeutic target for anticancer drug design.

Objective: Target compounds were designed to address the effect of different substitution patterns at the N atom of the carboxamide moiety on the bioactivity of this series.

Methods: Synthesis of the targeted compounds, crystallography, biological evaluation tests against human colon carcinoma (HCT-116), and Glide docking studies.

Potent trypanocidal curcumin analogs bearing a monoenone linker motif act on trypanosoma brucei by forming an adduct with trypanothione.

We have previously reported that curcumin analogs with a C7 linker bearing a C4-C5 olefinic linker with a single keto group at C3 (enone linker) display midnanomolar activity against the bloodstream form of Trypanosoma brucei. However, no clear indication of their mechanism of action or superior antiparasitic activity relative to analogs with the original di-ketone curcumin linker was apparent. To further investigate their utility as antiparasitic agents, we compare the cellular effects of curcumin and the enone linker lead compound 1,7-bis(4-hydroxy-3-methoxyphenyl)hept-4-en-3-one (AS-HK014) here.

Synthesis of marine-derived 3-alkylpyridinium alkaloids with potent antiprotozoal activity.

Given the pressing need for new antiprotozoal drugs without cross-resistance with current (failing) chemotherapy, we have explored 3-tridecylpyridinium alkaloids (3TPAs), derivatives of viscosamine, as antiparasitic agents. We have developed a simple synthetic route toward viscosamine and related cyclic and linear monomers and oligomers. Evaluation for cytotoxicity on the protozoan parasites Trypanosoma brucei, Leishmania spp.

Symmetrical choline-derived dications display strong anti-kinetoplastid activity.

Objectives: to investigate the anti-kinetoplastid activity of choline-derived analogues with previously reported antimalarial efficacy.

Methods: from an existing choline analogue library, seven antimalarial compounds, representative of the first-, second- and third-generation analogues previously developed, were assessed for activity against Trypanosoma and Leishmania spp. Using a variety of techniques, the effects of choline analogue exposure on the parasites were documented and a preliminary investigation of their mode of action was performed.

Curcuminoid analogs with potent activity against Trypanosoma and Leishmania species.

The natural curcuminoids curcumin (1), demethoxycurcumin (2) and bisdemethoxycurcumin (3) have been chemically modified to give 46 analogs and 8 pairs of 1:1 mixture of curcuminoid analogs and these parent curcuminoids and their analogs were assessed against protozoa of the Trypanosoma and Leishmania species. The parent curcuminoids exhibited low antitrypanosomal activity (EC(50) for our drug-sensitive Trypanosoma brucei brucei line (WT) of compounds 1, 2 and 3 are 2.5, 4.
