INTRODUCTION: RECIST 1.1 criteria are the standard for the response assessment of most solid tumors on computed tomography (CT). Nevertheless, the emergence of new classes of treatment in the lasts decades has brought new challenges in the response evaluation. EVIDENCE ACQUISITION: A PubMed online database literature search was performed in order to identify papers in English with full text available published up to September 2017. EVIDENCE SYNTHESIS: Some oncologic treatments, such as anti-angiogenic agents, immunotherapy and local treatments, have proven to be effective despite atypical patterns of responses...

Since the beginning of second decade of this century, when it was introduced in many oncologic scenarios, immunotherapy has become an important tool in the management of a growing number of cancers. Engaging the host immune system in cancer therapy seems to be useful, improving not only progression free survival but also overall survival, until the achieving the goal that many advanced cancers, previously considered without effective treatment options, have now become successfully treatable. Moreover, considering the relatively recent introduction of these drugs in clinical scenarios and the continuous releasing of new drugs, large validated clinical experiences are lacking and many issues are today debated; by the way, the evaluation of the response to immune-therapy poses major concerns...

Empirical data has shown that bivalent inhibitors can bind a given target protein significantly better than their monomeric counterparts. However, predicting the corresponding theoretical fold improvements has been challenging. The current work builds off the reacted-site probability approach to provide a straightforward baseline reference model for predicting fold-improvements in effective affinity of dimerized ligands over their monomeric counterparts. For the more familiar irreversibly linked bivalents, the model predicts a weak dependence on tether length and a scaling of the effective affinity with the 3/2 power of the monomer's affinity...

Drawbacks and limitations of recently available therapies to hepatocellular cancer (HCC) devoted the scientist to focus on emerging new strategies. ZnO nanoparticles (ZnONPs) based chemotherapeutics has been emanating as a promising approach to maximize therapeutic synergy facilitating the discovery of novel multitargeted combinations. In the present study we conjugated ZnONPs with ferulic acid (ZnONPs-FAC) characterized by computational, spectroscopic and microscopic techniques. In vitro anticancer potential has been evaluated by assessing cell viability, morphology, ROS generation, mitochondrial membrane permeability, comet assay, immunofluorescent staining of 8-OHdG, Ki67 and γ-H2AX, cell cycle analysis and western blot analysis and in vivo anticancer potential against DEN induced HCC was analyzed by histopathological and immunohistochemical methods...

The present study examined the extent to which Event Related Potentials (ERPs) evoked by disgusting, threatening and neutral photographic images were influenced by disgust propensity, disgust sensitivity and attentional control following exposure to disgusting information. Emotional cognition was manipulated by instructing participants to remember either disgusting or neutral sentences; participants in both groups then viewed emotional images while ERPs were recorded. Disgust propensity was associated with a reduced Late Positive Potential (LPP) gap between threatening and neutral stimuli (an effect driven by a rise in the LPP for neutral images) but only amongst individuals who were exposed to disgusting sentences...

BACKGROUND: Variation in the intensity of acute care treatment at the end of life is influenced more strongly by hospital and provider characteristics than patient preferences. OBJECTIVE: We sought to describe physicians' mental models (i.e., thought processes) when encountering a simulated critically and terminally ill older patient, and to compare those models based on whether their treatment plan was patient preference-concordant or preference-discordant. METHODS: Seventy-three hospital-based physicians from 3 academic medical centers engaged in a simulated patient encounter and completed a mental model interview while watching the video recording of their encounter...

Recent years have witnessed the emergence of bacterial semi-organelle encapsulins as promising platforms for bio-nanotechnology. To advance the development of encapsulins as nanoplatforms, a functional and structural basis of these assemblies is required. Encapsulin from Brevibacterium linens is known to be a protein-based vessel for an enzyme cargo in its cavity, which could be replaced with a foreign cargo resulting in a modified encapsulin. Here, we characterize the native structure of B. linens encapsulins with both native and foreign cargo using cryo-electron microscopy (cryo-EM)...

In the late 90's there was a change in both the route of transmission and the people at risk for sporotrichosis. This zoonotic cat-man alternative transmission route elicited changes in strategies to control the epidemic. There was a progressive increase in the number of cases involving especially children and the elderly. In addition to becoming hyperendemic, uncommon clinical pictures like immunoreactive clinical presentations or severe systemic cases have emerged. New species were identified and classified through molecular tools using more virulent clinical isolates, like S...

OBJECTIVE: The new epidemic of Zika virus infection raises grave concerns, especially with the increasingly-recognized link between emerging cases of microcephaly and this infectious disease. Besides small cranial dimensions, there are striking morphologic anomalies in the fetal brain. Key anomalies include cortical developmental malformations and a peculiar distribution of pathologic calcifications. These potentially indicate a new pattern of congenital central nervous system infection...

BACKGROUND: The knowledge of sinonasal vasculature is inevitable in transnasal neurosurgery. We performed an anatomical study on the sphenopalatine artery from the perspective of skull base procedures. METHODOLOGY: To analyse the anatomical landmarks of the sphenopalatine artery, arterial skull corrosion casts (26 head halves) underwent endoscopic transnasal phantom surgery. Furthermore, we performed microsurgical dissection on formaldehyde-fixated cadavers with arterial perfusion (14 head halves) as well as studied Cone Beam CT-scans of anonymised patients and cadavers (115 head sides)...

COPD patients are burdened with a daily risk of acute exacerbation and loss of control, which could be mitigated by effective, on-demand decision support tools. In this study, we present a machine learning-based strategy for early detection of exacerbations and subsequent triage. Our application uses physician opinion in a statistically and clinically comprehensive set of patient cases to train a supervised prediction algorithm. The accuracy of the model is assessed against a panel of physicians each triaging identical cases in a representative patient validation set...

In 1988, the World Health Assembly launched the Global Polio Eradication Initiative. Among the three wild poliovirus serotypes, only wild poliovirus (WPV) type 1 (WPV1) has been detected since 2012. Since 2014, Pakistan, Afghanistan, and Nigeria remain the only countries with continuing endemic WPV1 transmission. This report describes activities conducted and progress made toward the eradication of poliovirus in Pakistan during January 2016-July 2017 and provides an update to previous reports (1,2). In 2016, Pakistan reported 20 WPV1 cases, a 63% decrease compared with 54 cases in 2015 (3)...

BACKGROUND The incarceration of a segment of bowel within a groin hernia can result in intestinal strangulation if hernia treatment is delayed. Once intestinal strangulation occurs, a bowel resection may be required, and there is an overall increased risk for postoperative complications. The aim of this study was to identify biomarkers to predict the severity of an incarcerated groin hernia. MATERIAL AND METHODS We retrospectively evaluated the records of 95 patients with incarcerated groin hernias who underwent emergency surgical correction of the hernias...

Prepectoral breast reconstruction has emerged as an excellent technique for postmastectomy reconstruction, as it allows for full preservation of a patient's pectoralis major muscle and chest wall function. This reduces pain, eliminates animation deformity, and results in high patient satisfaction. Safely performed prepectoral breast reconstruction requires a careful patient selection process before committing to the procedure, taking into account comorbidities, radiation status, and oncologic criteria such as tumor location and breast cancer stage...

Critically ill patients require complex care in a technologically sophisticated environment where they are highly vulnerable to pressure-related injuries. However, pressure injury (PI) development remains a multifactorial phenomenon in critically ill persons; true risk is both pervasive and elusive. The purpose of this comprehensive review of the empirical literature was to examine the risk factors associated with PIs among adult patients admitted to contemporary intensive care units (ICUs). Inclusion criteria stipulated publications were to be peer-reviewed, quantitative studies with a focus on pressure ulcer (PU) risk factors in adult critical care patients published between 2010 and 2016 in which statistical analysis involved multivariate analysis using PU development as the outcome variable...

Optimal wound healing with negative pressure wound therapy (NPWT) relies on a properly sealed vacuum system. Anatomically difficult wounds impair the adhesive dressing, which results in air leaks that disrupt the integrity of the NPWT system and hinder wound healing. OBJECTIVE: The authors demonstrate a new technique using a cyanoacrylate-based tissue adhesive to maintain an airtight, durable seal in NPWT. MATERIALS AND METHODS: A 52-year-old woman with a degloving injury to the right thigh extending into the groin, resulting in massive necrosis, presented to the emergency department...
