Nasopharyngeal carcinoma (NPC) is a type of cancer endemic in Asia, including Malaysia, Southern China, Hong Kong and Taiwan. Treatment resistance, particularly in recurring cases, remains a challenge. Thus, studies to develop novel therapeutic agents are important. Potential therapeutic compounds may be effectively examined using two-dimensional (2D) cell culture models, three-dimensional (3D) spheroid models or in vivo animal models. The majority of drug assessments for cancers, including for NPC, are currently performed with 2D cell culture models...

REVIEW
Willis Gwenzi, Nhamo Chaukura, Chicgoua Noubactep, Fungai N D Mukome
Approximately 600 million people lack access to safe drinking water, hence achieving Sustainable Development Goal 6 (Ensure availability and sustainable management of water and sanitation for all by 2030) calls for rapid translation of recent research into practical and frugal solutions within the remaining 13 years. Biochars, with excellent capacity to remove several contaminants from aqueous solutions, constitute an untapped technology for drinking water treatment. Biochar water treatment has several potential merits compared to existing low-cost methods (i...

Herein we report a rapid low cost one step green synthetic method using Actinidia deliciosa fruit extract for preparation of stable and multifunctional silver and gold nanoparticles. The synthesized nanoparticles were successfully used as green catalysts for the reduction of 4-nitrophenol (4-NP) and methylene blue (MB). The enhanced biological activity of the prepared nanoparticles was investigated based on its highly stable antioxidant, anticancer and bactericidal effects. TEM micrographs showed that the silver nanoparticles (AgNPs) formed were predominantly spherical in shape having diameters ranging from 25 to 40nm, while gold nanoparticles (AuNPs) shown particle size ranges from 7 to 20nm...

Shangtao Liang, Qi Luo, Qingguo Huang
Natural laccase-mediator systems have been well recognized as an eco-friendly and energy-saving approach in environmental remediation, whose further application is however limited by the high cost of natural mediators and relatively long treatment time span. This study evaluated the water extract of soybean meal, a low-cost compound system, in mediating the laccase catalyzed degradation of a model contaminant of emerging concern, sulfadimethoxine (SDM), and demonstrated it as a promising alternative mediator for soil and water remediation...

In Sub-Saharan Africa, malaria remains a major cause of morbidity and mortality among children under 5, due to lack of access to prompt and appropriate diagnosis and treatment. Many countries have scaled-up community health workers (CHWs) as a strategy towards improving access. The present study was a cost-effectiveness analysis of the introduction of malaria rapid diagnostic tests (mRDTs) performed by CHWs in two areas of moderate-to-high and low malaria transmission in rural Uganda. CHWs were trained to perform mRDTs and treat children with artemisinin-based combination therapy (ACT) in the intervention arm while CHWs offered treatment based on presumptive diagnosis in the control arm...

Diverticulosis and diverticular disease of the colon are common conditions in Western countries. The incidence and prevalence of these diseases are increasing and becoming significant for health systems. A growing body of knowledge is shifting the paradigm of the pathogenesis and treatment of diverticular disease. Low-grade inflammation, altered intestinal microbiota, visceral hypersensitivity, and abnormal colonic motility have been identified as factors leading to diverticular disease. The risk of developing diverticulitis among individuals with diverticulosis is lower than 10 to 25%...

Breast cancer is the most common malignant tumor among women of reproductive age and is also the most costly according to European reports. In this context, the aim of the present review is to identify factors that make breast cancer in premenopausal women an epidemiological challenge in developing countries. Epidemiological aspects of breast cancer, including risk factors, early detection methods, and treatment, are addressed. Breast cancer in premenopausal women should be included in the political and strategic agendas in developing countries to direct the necessary resources for prevention, detection, and control...

Rajeshwari Sundaram, Ling Ma, Subhashis Ghoshal
Recurrent events are often encountered in medical follow up studies. In addition, such recurrences have other quantities associated with them that are of considerable interest, for instance medical costs of the repeated hospitalizations and tumor size in cancer recurrences. These processes can be viewed as point processes, i.e. processes with arbitrary positive jump at each recurrence. An analysis of the mean function for such point processes have been proposed in the literature. However, such point processes are often skewed, leading to median as a more appropriate measure than the mean...

Angelo Pricolo, Suzanne Nielsen
ISSUES: Numerous studies and systematic reviews have concluded that naloxone for take-home use is an effective intervention to reduce overdose morbidity and mortality, with few side effects and no abuse potential. One barrier to supply is that naloxone has traditionally been a prescription medication. In May 2015, the Therapeutic Goods Administration of Australia announced the intention to down-schedule naloxone when used for the treatment of opioid overdose, enabling sale in pharmacies without a prescription...

BACKGROUND AND AIM: In Asia-Pacific where cost is a major concern, peginterferon plus ribavirin (PR) often remain as the standard of care in chronic hepatitis C (CHC) treatment, while the direct-acting antivirals (DAAs) are commonly recommended as retreatment. Newer DAAs can achieve a sustained virological response (SVR) of nearly 100% with pan-genotypic coverage, that is "Highly Effective DAAs." We aimed to investigate the most desirable cost range for the Highly Effective DAAs using Hong Kong as an example...

BACKGROUND: Hemodialysis (HD) vascular access failure is one of the most important causes of morbidity and contributes to the cost of dialysis care. There is paucity of data evaluating long-term monitoring of C-reactive protein (CRP) on outcome of HD vascular access. METHODS: We conducted a retrospective study to investigate whether variability of serum CRP level was associated with vascular access failure rate over a 7-year period. A total of 318 HD patients were included...

WHAT IS KNOWN AND OBJECTIVE: With the increasing prevalence of diabetes, the physician-centred model is challenged to deliver holistic care in Asia. Diabetes may be managed effectively within a multidisciplinary collaborative care model; however, evidence on its effectiveness in Asian patients is lacking. Therefore, the primary objective was to evaluate the clinical outcomes of multidisciplinary collaborative care vs physician-centred care in diabetes. The secondary objectives were to evaluate humanistic and economic outcomes among the two types of care...

In many medical care markets with limited profit potential, firms often have little incentive to innovate. These include the market for rare diseases, "neglected" tropical diseases, and personalized medicine. Governments and not-for-profit organizations promote innovation in such markets but empirical evidence on the policy effect is limited. We study this issue by analyzing the impact of a demand-side policy in Japan, which reduces the cost sharing of patients with some rare and intractable diseases and attempts to establish and promote the treatment of those diseases...

BACKGROUND: Follow-up aims to precociously identify recurrences, metastases or treatment-related adverse events so as to undertake the appropriate therapy. Guidelines admit lack of knowledge on optimal surveillance schedule, but suggest follow-up based on experts' opinion and risk stratification. To identify the impact, if any, of regular follow-up, we interrogated our prospectively collected database whether early detection of recurrences affected both clinical management and, likely, the outcome...

BACKGROUND: Patients with moderate-to-severe psoriasis may be treated with above-label doses of biologics in an attempt to optimize outcomes. Dose escalation will have an effect on the cost of treatment. OBJECTIVE: To examine costs related to above-label use of etanercept, adalimumab, and ustekinumab among patients with moderate-to-severe psoriasis. METHODS: A retrospective study was performed using a large U.S. claims database. Patients were included in the study if they were aged ≥ 18 years with a diagnosis of psoriasis (excluding psoriatic arthritis) and had at least 1 medication fill for etanercept, adalimumab, or ustekinumab between January 1, 2011, and June 30, 2012...

Enhanced knowledge of the biological and genetic basis of cancer is re-defining target population for new treatments. In oncology, potential targets for a new therapeutic agent often include various solid and hematologic malignancies that share common signaling pathways. New agents are often tested in multiple tumor types across which information can be borrowed. We propose a hierarchical Bayesian design (HBD) to simultaneously test a novel agent in multiple groups for randomized phase II clinical trials with binary endpoints...
