Understanding the Female Asian American Facial Aesthetic Patient

Background: As facial aesthetic procedures have become more widely accepted, the racial and ethnic diversity of aesthetic patient populations has increased. Asian Americans represent a growing segment of this population and have specific aesthetic concerns that should be differentiated from the broader Caucasian population. Objective: An online study was designed to survey facial aesthetic concerns, treatment priorities, and future treatment considerations among a US-based population of Asian American women. Materials and Methods: A total of 403 participants ages 30 to 65 years reported perspectives on facial aging, current facial conditions, most bothersome facial areas, most/least likely to be treated first, awareness of treatment options and consideration rates, and motives/barriers impacting the consideration rate of injectable treatments. Results: Treatment interests reflected predominant issues; uneven skin tone, wrinkles, and sun damage. Most bothersome facial areas included the periorbital area, forehead, and submental area, and also among areas designated as most likely to treat first. The majority of participants would consider injectables. However, safety/side effects, cost, and concerns about not looking natural were primary barriers. Conclusion: Understanding the aesthetic concerns and priorities specific to Asian American women may help guide treatment plans more aligned with the goals and expectations of this patient population.

A Numerically Stable Sub-optimal Parallel Sage Adaptive Filter

A novel method of sub optimal Sage adaptive Kalman Filter is presented in this paper. This new method shows effectively improved numerical stability by means of synthetically restraining the filter's divergence. A parallel filter structure of adding a concomitant filter is designed to eliminate system biases that the standard Sage adaptive filter always suffers, and the accuracy is improved.
Graph theory analysis of resting‐state functional magnetic resonance imaging in essential tremor

Essential tremor (ET) is a neurological disease with both motor and nonmotor manifestations; however, little is known about its underlying brain basis. Furthermore, the overall organization of the brain network in ET remains largely unexplored. We investigated the topological properties of brain functional network, derived from resting‐state functional magnetic resonance imaging (MRI) data, in 23 ET patients versus 23 healthy controls. Graph theory analysis was used to assess the functional network organization. At the global level, the functional network of ET patients was characterized by lower small‐worldness values than healthy controls—less clustered functionality of the brain. At the regional level, compared with the healthy controls, ET patients showed significantly higher values of global efficiency, cost and degree, and a shorter average path length in the left inferior frontal gyrus (pars opercularis), right inferior temporal gyrus (posterior division and temporo‐occipital part), right inferior lateral occipital cortex, left paracingulate, bilateral precuneus bilaterally, left lingual gyrus, right hippocampus, left amygdala, nucleus accumbens bilaterally, and left middle temporal gyrus (posterior part). In addition, ET patients showed significant higher local efficiency and clustering coefficient values in frontal medial cortex bilaterally, subcallosal cortex, posterior cingulate cortex, parahippocampal gyri bilaterally (posterior division), right lingual gyrus, right cerebellar flocculus, right postcentral gyrus, right inferior semilunar lobule of cerebellum and culmen of vermis. Finally, the right intracalcarine cortex and the left orbitofrontal cortex showed a shorter average path length in ET patients, while the left frontal operculum and the right planum polare showed a higher betweenness centrality in ET patients. In conclusion, the efficiency of the overall brain functional network in ET is disrupted. Further, our results support the concept that ET is a disorder that disrupts widespread brain regions, including those outside of the brain regions responsible for tremor.
Intracellular Staphylococcus aureus Elicits the Production of Host Very Long-Chain Saturated Fatty Acids with Antimicrobial Activity

As a facultative intracellular pathogen, Staphylococcus aureus is able to invade and proliferate within many types of mammalian cells. Intracellular bacterial replication relies on host nutrient supplies and, therefore, cell metabolism is closely bound to intracellular infection. Here, we investigated how S. aureus invasion affects the host membrane-bound fatty acids. We quantified the relative levels of fatty acids and their labelling pattern after intracellular infection by gas chromatography-mass spectrometry (GC-MS). Interestingly, we observed that the levels of three host fatty acids—docosanoic, eicosanoic and palmitic acids—were significantly increased in response to intracellular S. aureus infection. Accordingly, labelling carbon distribution was also affected in infected cells, in comparison to the uninfected control. In addition, treatment of HeLa cells with these three fatty acids showed a cytoprotective role by directly reducing S. aureus growth.
Repair of Critical‐Sized Long Bone Defects Using Dipyridamole‐Augmented 3D‐Printed Bioactive Ceramic Scaffolds

There are over two million long bone defects treated in the United States annually, of which ~5% will not heal without significant surgical intervention. While autogenous grafting is the standard of care in simple defects, a customized scaffold for large defects in unlimited quantities is not available. Recently, a three‐dimensionally (3D)‐printed bioactive ceramic (3DPBC) scaffold has been successfully utilized in the of repair critical‐sized (CSD) long bone defects in vivo. In this study, 3DPBC scaffolds were augmented with dipyridamole (DIPY), an adenosine A2A receptor (A2AR) indirect agonist, because of its known effect to enhance bone formation. CSD full thickness segmental defects (~11 mm × full thickness) defects were created in the radial diaphysis in New Zealand white rabbits (n = 24). A customized 3DPBC scaffold composed of β‐tricalcium phosphate was placed into the defect site. Groups included scaffolds that were collagen‐coated (COLL), or immersed in 10, 100, or 1,000 μM DIPY solution. Animals were euthanized 8 weeks post‐operatively and the radii/ulna‐scaffold complex retrieved en bloc, for micro‐CT, histological, and mechanical analysis. Bone growth was assessed exclusively within scaffold pores and evaluated by microCT and advanced reconstruction software. Biomechanical properties were evaluated utilizing nanoindentation to assess the newly regenerated bone for elastic modulus (E) and hardness (H). MicroCT reconstructions illustrated bone in‐growth throughout the scaffold, with an increase in bone volume dependent on the DIPY dosage. The histological evaluation did not indicate any adverse immune response while revealing progressive remodeling of bone. These customized biologic 3DPBC scaffolds have the potential of repairing and regenerating bone. © 2019 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Autophosphorylation activates c-Src kinase through global structural rearrangements

The prototypical kinase c-Src plays an important role in numerous signal transduction pathways, where its activity is tightly regulated by two phosphorylation events. Phosphorylation at a specific tyrosine by C-terminal Src kinase inactivates c-Src, whereas autophosphorylation is essential for the c-Src activation process. However, the structural consequences of the autophosphorylation process still remain elusive. Here we investigate how the structural landscape of c-Src is shaped by nucleotide binding and phosphorylation of Tyr416 using biochemical experiments, hydrogen/deuterium exchange MS, and atomistic molecular simulations. We show that the initial steps of kinase activation involve large rearrangements in domain orientation. The kinase domain is highly dynamic and has strong cross-talk with the regulatory domains, which are displaced by autophosphorylation. Although the regulatory domains become more flexible and detach from the kinase domain because of autophosphorylation, the kinase domain gains rigidity, leading to stabilization of the ATP binding site and a 4-fold increase in enzymatic activity. Our combined results provide a molecular framework of the central steps in c-Src kinase regulation process with possible implications for understanding general kinase activation mechanisms.
The Role of Breast Cancer Stem Cells as a Prognostic Marker and a Target to Improve the Efficacy of Breast Cancer Therapy

Breast cancer is the most common form of tumor in women and the leading cause of cancer-related mortality. Even though the major cellular burden in breast cancer is constituted by the so-called bulk tumor cells, another cell subpopulation named cancer stem cells (CSCs) has been identified. The latter have stem features, a self-renewal capacity, and the ability to regenerate the bulk tumor cells. CSCs have been described in several cancer types but breast cancer stem cells (BCSCs) were among the first to be identified and characterized. Therefore, many efforts have been put into the phenotypic characterization of BCSCs and the study of their potential as prognostic indicators and therapeutic targets. Many dysregulated pathways in BCSCs are involved in the epithelial–mesenchymal transition (EMT) and are found up-regulated in circulating tumor cells (CTCs), another important cancer cell subpopulation, that shed into the vasculature and disseminate along the body to give metastases. Conventional therapies fail at eliminating BCSCs because of their quiescent state that gives them therapy resistance. Based on this evidence, preclinical studies and clinical trials have tried to establish novel therapeutic regimens aiming to eradicate BCSCs. Markers useful for BCSC identification could also be possible therapeutic methods against BCSCs. New approaches in drug delivery combined with gene targeting, immunomodulatory, and cell-based therapies could be promising tools for developing effective CSC-targeted drugs against breast cancer.
In Vitro Toxicity of TiO2:SiO2 Nanocomposites with Different Photocatalytic Properties

The enormous technological relevance of titanium dioxide (TiO2) nanoparticles (NPs) and the consequent concerns regarding potentially hazardous effects that exposure during production, use, and disposal can generate, encourage material scientists to develop and validate intrinsically safe design solution (safe-by-design). Under this perspective, the encapsulation in a silica dioxide (SiO2) matrix could be an effective strategy to improve TiO2 NPs safety, preserving photocatalytic and antibacterial properties. In this work, A549 cells were used to investigate the toxic effects of silica-encapsulated TiO2 having different ratios of TiO2 and SiO2 (1:1, 1:3, and 3:1). NPs were characterized by electron microscopy and dynamic light scattering, and cell viability, oxidative stress, morphological changes, and cell cycle alteration were evaluated. Resulting data demonstrated that NPs with lower content of SiO2 are able to induce cytotoxic effects, triggered by oxidative stress and resulting in cell necrosis and cell cycle alteration. The physicochemical properties of NPs are responsible for their toxicity. Particles with small size and high stability interact with pulmonary cells more effectively, and the different ratio among silica and titania plays a crucial role in the induced cytotoxicity. These results strengthen the need to take into account a safe(r)-by-design approach in the development of new nanomaterials for research and manufacturing.
Dietary compounds to reduce in vivo inorganic arsenic bioavailability.

It is estimated that approximately 200 million people are exposed to arsenic levels above the WHO provisional guideline value, and various agencies have indicated the need to reduce this exposure. In view of the difficulty of removing arsenic from water and food, one alternative is to reduce its bioavailability (the amount that reaches the systemic circulation after ingestion). In this study, dietary components [glutathione, tannic acid and Fe(III)] were used to achieve this goal. As(III) or As(V) (1 mg/kg body weight) was administered daily to BALB/c mice, along with the dietary components, for 15 days. The results confirm the efficacy of Fe(III) and glutathione as reducers of arsenic bioavailability and tissue accumulation. Also, these treatments did not result in reductions of Ca, K, P and Fe contents in the liver. These data suggest that use of these two compounds could be part of valid strategies for reducing inorganic arsenic exposure in chronically exposed populations.
Two novel mutations in TTN of a patient with congenital myopathy: A case report

Early‐onset myopathies show a wide spectrum of phenotypes and are composed of various types of inherited neuromuscular diseases, making it difficult to diagnose. TTN mutation‐related myopathy is a known cause of early‐onset myopathy. Since a next‐generation sequencing (NGS) has enabled sequencing of the vast amount of DNA, TTN, which is the longest coding sequence of any human gene, mutations can now be revealed. We report a 10‐year‐old female with severe congenital muscular weakness and delayed motor development since birth.
Randomized Phase II Study of Weekly Paclitaxel plus Carboplatin Versus Biweekly Paclitaxel plus Carboplatin for Patients with Previously Untreated Advanced Non‐Small Cell Lung Cancer

Abstract Lessons Learned. This clinical trial, evaluating the efficacy and safety of a carboplatin plus paclitaxel regimen in a biweekly or weekly schedule instead of the more toxic 3‐weekly administration, showed that the weekly regimen was better in efficacy than the biweekly regimen, with mild toxicities, for patients with non‐small cell lung cancer (NSCLC). The weekly carboplatin plus paclitaxel regimen could be considered as an alternative to the 3‐weekly regimen in Japanese patients with NSCLC. Background. Combination therapy comprising carboplatin (C) and paclitaxel (P) is the most commonly used regimen for the treatment of advanced non‐small cell lung cancer (NSCLC). Common toxicities associated with the regimen, such as neuropathy and myelosuppression, cause its discontinuation. In the present study, we conducted a clinical trial evaluating the efficacy of biweekly (B) and weekly (W) PC therapy to identify the appropriate chemotherapy schedule for Asian patients. Methods. Chemonaive patients with IIIB/IV NSCLC and a performance status of 0–1 were randomly assigned to a biweekly regimen (paclitaxel 135 mg/m2 with carboplatin area under the curve [AUC] 3 on days 1 and 15 of every 4 weeks) or to a weekly regimen (paclitaxel 90 mg/m2 on days 1, 8, and 15 with carboplatin AUC 6 on day 1 of every 4 weeks). Results. A total of 140 patients were enrolled in the study. The objective response rates (ORRs) were 28.1% (B) and 38.0% (W). The most common toxicity was neutropenia, with incidence rates of 62.0% (B) and 57.8% (W). Progression‐free survivals (PFSs) were 4.3 months (B) and 5.1 months (W), and overall survival durations were 14.2 months (B) and 13.3 months (W). Conclusion. The ORR and PFS in the weekly regimen were better than those in the biweekly schedule, although a statistical difference was not observed. The toxicity profile was generally mild for both regimens. The weekly CP regimen was suitable to be considered as an alternative to the current 3‐weekly regimen in NSCLC treatment.
Geographical variations in ocular and extra-ocular manifestations in Behçet's disease.

OBJECTIVE Behçet's disease (BD) is a rare vasculitis that results in multi-organ inflammatory disease. At-risk populations are most prevalent in the Middle East and East Asia. Clinical data on BD in Western countries, especially in the United States, are scarce. We have compared clinical patterning of BD vasculitis in two geographically defined patient cohorts in the Western United States and Iran. METHODS Comparative analysis of a retrospective cohort of 56 patients with BD evaluated at Stanford University Hospital between 2000 and 2016 and a cohort of 163 patients from the BD Registry at Tehran University of Medical Sciences. Clinical, demographic, laboratory, and treatment data were available. Comparisons were performed using descriptive statistics, Student's t-test, and χ2-test. RESULTS The Stanford patients with BD were significantly younger at disease onset, had a higher proportion of females, and had longer disease duration than Iranian patients with BD. Genital ulcers, skin, joint, neurological, vascular, cardiopulmonary manifestations were all significantly more common in the Stanford cohort and 38% of Stanford patients had four or more organ systems involved compared with approximately 10% of Iranian patients. In contrast, Stanford patients had fewer ocular lesions (Stanford 21.4% vs. Iran 53.4% p<0.05), with the biggest difference seen for retinal vasculitis. CONCLUSION Patients with BD from the Western US have a more severe disease course when compared to Iranian patients with BD, as demonstrated by earlier onset and a higher rate of multi-organ involvement. The high risk of Iranian patients with BD developing vasculitis of ocular structures suggests distinct pathomechanisms driving ocular versus extra-ocular BD.
Role of Tricellular Tight Junction Protein Lipolysis-Stimulated Lipoprotein Receptor (LSR) in Cancer Cells

Maintaining a robust epithelial barrier requires the accumulation of tight junction proteins, LSR/angulin-1 and tricellulin, at the tricellular contacts. Alterations in the localization of these proteins temporarily cause epithelial barrier dysfunction, which is closely associated with not only physiological differentiation but also cancer progression and metastasis. In normal human endometrial tissues, the endometrial cells undergo repeated proliferation and differentiation under physiological conditions. Recent observations have revealed that the localization and expression of LSR/angulin-1 and tricellulin are altered in a menstrual cycle-dependent manner. Moreover, it has been shown that endometrial cancer progression affects these alterations. This review highlights the differences in the localization and expression of tight junction proteins in normal endometrial cells and endometrial cancers and how they cause functional changes in cells.
Hydrogen Sulfide as a Toxic Product in the Small–Large Intestine Axis and its Role in IBD Development

The small–large intestine axis in hydrogen sulfide accumulation and testing of sulfate and lactate in the gut–gut axis of the intestinal environment has not been well described. Sulfate reducing bacteria (SRB) of the Desulfovibrio genus reduce sulfate to hydrogen sulfide and can be involved in ulcerative colitis development. The background of the research was to find correlations between hydrogen sulfide production under the effect of an electron acceptor (sulfate) and donor (lactate) at different concentrations and Desulfovibrio piger Vib-7 growth, as well as their dissimilatory sulfate reduction in the intestinal small–large intestinal environment. Methods: Microbiological, biochemical, and biophysical methods, and statistical processing of the results (principal component and cross-correlation analyses) were used. Results: D. piger Vib-7 showed increased intensity of bacterial growth and hydrogen sulfide production under the following concentrations of sulfate and lactate: 17.4 mM and 35.6 mM, respectively. The study showed in what kind of intestinal environment D. piger Vib-7 grows at the highest level and produces the highest amount of hydrogen sulfide. Conclusions: The optimum intestinal environment of D. piger Vib-7 can serve as a good indicator of the occurrence of inflammatory bowel diseases; meaning that these findings can be broadly used in medicine practice dealing with the monitoring and diagnosis of intestinal ailments.
Organizing for sustainable inter-organizational collaboration in health care processes

ABSTRACT Integrating health care services has proven to be important from both the patient and organizational perspectives. This study explores what defines a perceived well-functioning collaboration in the inter-organizational process of providing assistive devices in Sweden. Two focus groups comprising participants with profound knowledge of collaboration were performed, and data were analyzed in five steps, resulting in a data structure. Results yield the identification of three interacting processes: coordinating efforts to patient needs, ensuring evidence-based practice, and planning for efficient use of resources. These processes affected one another, and, therefore, would likely not have been effectively managed separately. The study contributes to theories of process management and organization by specifically focusing on how to analyze and improve sustainable collaboration in health care processes at both the management and professional levels. Theoretical frameworks that show different ways of organizing collaboration, as well as the concepts of action nets and boundary objects, can support both analysis and planning of collaboration. The intention would be to develop integration in inter-organizational health care processes, resulting in more person-centered care.
Development of a Paper-Based Sensor Compatible with a Mobile Phone for the Detection of Common Iron Formulas Used in Fortified Foods within Resource-Limited Settings

A lack of quality control tools limits the enforcement of fortification policies. In alignment with the World Health Organization’s ASSURED criteria (affordable, sensitive, specific, user-friendly, rapid and robust, equipment-free, and deliverable), a paper-based assay that interfaces with a smartphone application for the quantification of iron fortificants is presented. The assay is based on the Ferrozine colorimetric method. The reaction started after deposition of the 5 µL aqueous sample and drying. After developing color, pixel intensity values were obtained using a smartphone camera and image processing software or a mobile application, Nu3px. From these values, the actual iron concentration from ferrous sulfate and ferrous fumarate was calculated. The limits of detection, quantification, linearity, range, and errors (systematic and random) were ascertained. The paper-based values from real samples (wheat flour, nixtamalized corn flour, and infant formula) were compared against atomic emission spectroscopy. The comparison of several concentrations of atomic iron between the spectrophotometric and paper-based assays showed a strong positive linear correlation (y = 47.01x + 126.18; R2 = 0.9932). The dynamic range (5.0–100 µg/mL) and limit of detection (3.691 µg/mL) of the paper-based assay are relevant for fortified food matrices. Random and systematic errors were 15.9% and + 8.65 µg/g food, respectively. The concept can be applied to limited-resource settings to measure iron in fortified foods.
