REVIEW
M Ashraf, A A R Souka
The recent VIEW studies have demonstrated the non-inferiority of monthly and bi-monthly aflibercept in the management of wet age related macular degeneration (AMD) compared with ranibizumab. However, the current data are limited mainly to fixed dosing regimens with few studies looking at flexible dosing regimens of aflibercept in wet AMD. In addition, recent data from the VIEW 96 week extension has shown that patients being shifted from fixed dosing regimens to PRN have shown a drop in visual acuity and increase in central macular thickness...

The clinical effectiveness of patient-controlled analgesia has been demonstrated in a variety of settings. However, patient-controlled analgesia is rarely utilised in the emergency department. The aim of this study was to compare the cost-effectiveness of patient-controlled analgesia vs. standard care in participants admitted to hospital from the emergency department with pain due to traumatic injury or non-traumatic abdominal pain. Pain scores were measured hourly for 12 h using a visual analogue scale. Cost-effectiveness was measured as the additional cost per hour in moderate to severe pain avoided by using patient-controlled analgesia rather than standard care (the incremental cost-effectiveness ratio)...

BACKGROUND: Anterior debridement/bone grafting/posterior instrumentation is a common selection for the treatment of lumbar spinal tuberculosis (LST). To date, no study has focused on the prognostic factors for recovery after this surgery. METHODS: 144 patients experienced anterior debridement/bone grafting/posterior instrumentation for LST were included. The recovery rate based on the Japanese Orthopedic Association (JOA) score was used to assess recovery. The Kaplan-Meier method and Cox regression analysis were used to identify the prognostic factors for recovery postoperatively...

The excessive discharge of phosphorus (P) from sewage treatment plants and runoff from agricultural fields is causing a rapid contamination of water resources worldwide. Several materials have been evaluated for the removal of excess P from waste supplies, but designing a cost-effective and environmental friendly substrate is essential for the efficient P removal. In this study, bio-calcite (BC) derived from waste hen eggshell was subjected to thermal treatments (CBC). The BC and CBC further modified via magnesiothermal treatments to produced MBC and MCBC, respectively, and evaluated as a novel green sorbent for P removal from aqueous solutions...

Heavy-metal-contaminated soil threatens human health and environmental safety. Complete remediation of contaminated soil is expensive; therefore, phytomanagement has emerged as a cost-effective alternative. The current study investigated mulberry tree (Morus alba) plantation, silkworm cultivation, and silk production as phytomanagement options. Results defined the safety of planting mulberry trees in soils with lead (Pb) and arsenic (As) concentrations lower than 369 and 180mgkg(-1), respectively. Silkworms fed with mulberry leaves collected from slightly contaminated soil exhibited productive growth and normal silk production...

The analysis of the network structure of the functional connectivity data constructed from fMRI images provides basic information about functions and features of the brain activity. We focus on the two features which are considered as relevant to the brain activity, the criticality and the constraint regarding energy consumptions. Within a wide variety of complex systems, the critical state occurs associated with a phase transition between distinct phases, random one and order one. Although the hypothesis that human brain activity is also in a state of criticality is supported by some experimental results, it still remains controversial...

In lung inflammation, neutrophils are the first leukocytes migrating to an inflammatory site, eliminating pathogens by multiple mechanisms. The term "migration" describes several stages of neutrophil movement to reach the site of inflammation, of which the passage of the interstitium and basal membrane of the airway are necessary to reach the site of bronchial inflammation. Currently, several methods exist (e.g., Boyden Chamber, under-agarose assay, or microfluidic systems) to assess neutrophil mobility. However, these methods do not allow for parameterization on single cell level, that is, the individual neutrophil pathway analysis is still considered challenging...

BACKGROUND: Streptococcus pneumoniae (SP) pneumonia is often treated empirically as diagnosis is challenging because of the lack of a perfect test. Using BinaxNOW-SP, a urinary antigen test, as an add-on to standard cultures may not only increase diagnostic yield but also increase costs. OBJECTIVE: To estimate the sensitivity and specificity of BinaxNOW-SP and subsequently estimate the cost-effectiveness of adding BinaxNOW-SP to the diagnostic work-up. DESIGN: We fit a Bayesian latent-class meta-analysis model to obtain estimates of BinaxNOW-SP accuracy that adjust for the imperfect accuracy of culture...

Antibodies that antagonize cell signaling pathways specific to their targeted receptor are invaluable tools to study and treat malignancies, but their utility is limited by high production costs and treatment dosages. Researchers have shown that antibodies conjugated to nanoparticles display increased affinity for their target relative to freely delivered antibodies due to multivalency, and this study investigates how this multivalency can enable antibody-nanoparticle conjugates to inhibit oncogenic cell signaling more effectively than freely delivered antibodies...
