Abstract
Background Although existing psoriasis treatments are effective and well tolerated in many patients, there is still a need for new effective targeted treatment options. Tofacitinib is an oral Janus kinase inhibitor that has been investigated in patients with moderate‐to‐severe chronic plaque psoriasis. Objectives To consider the benefits and risks of tofacitinib in patients with moderate‐to‐severe psoriasis. Methods Data were pooled from one phase II, four phase III and one long‐term extension study comprising 5204 patient‐years of tofacitinib treatment. Efficacy end points included patients achieving Physician's Global Assessments of ‘clear’ or ‘almost clear’, ≥ 75% and ≥ 90% reduction in Psoriasis Area and Severity Index (coprimary end points) and improvements in Dermatology Life Quality Index score, Hospital Anxiety and Depression Scale depression score and Itch Severity Item score, at weeks 16 and 52. Safety data were summarized for 3 years of tofacitinib exposure. Results Tofacitinib 5 and 10 mg twice daily (BID) showed superiority over placebo for all efficacy end points at week 16, with response maintained for 52 weeks of continued treatment. Tofacitinib improved patients’ quality of life and was well tolerated. Rates of safety events of interest (except herpes zoster) were similar to those in the published literature and healthcare databases for other systemic psoriasis therapies. Tofacitinib 10 mg BID demonstrated greater efficacy than 5 mg BID. Conclusions Tofacitinib has a benefit–risk profile in moderate‐to‐severe psoriasis consistent with that of other systemic treatments. What's already known about this topic? Psoriasis is a chronic, systemic inflammatory disease, which has a significant impact on patients’ health‐related quality of life. Although several existing psoriasis treatments are efficacious and well tolerated in many patients, some patients require treatment switching, and a proportion of patients remain untreated or undertreated. Potential challenges to the use of existing therapies include safety issues and limited efficacy in some patients with conventional oral psoriasis treatments, inconvenience of topical treatments and the requirement for parenteral administration of biologics.
What does this study add? Consistent efficacy and a safety profile consistent with that seen in rheumatoid arthritis, psoriatic arthritis and ulcerative colitis were demonstrated for oral tofacitinib in patients with moderate‐to‐severe psoriasis. Tofacitinib has a benefit–risk profile in patients with moderate‐to‐severe psoriasis that is consistent with that of other systemic psoriasis treatments.

Abstract
Biopolymers are increasingly employed for neuroscience applications as scaffolds to drive and promote neural regrowth, thanks to their ability to mediate the upload and subsequent release of active molecules and drugs. Synthetic degradable polymers are characterized by different responses ranging from tunable distension or shrinkage to total dissolution, depending on the function they are designed for. In this paper we present a biocompatible microfabricated poly-ε-caprolactone (PCL) scaffold for primary neuron growth and maturation that has been optimized for the in vitro controlled release of brain-derived neurotrophic factor (BDNF). We demonstrate that the designed morphology confers to these devices an enhanced drug delivery capability with respect to monolithic unstructured supports. After incubation with BDNF, micropillared PCL devices progressively release the neurotrophin over 21 days in vitro. Moreover, the bioactivity of released BDNF is confirmed using primary neuronal cultures, where it mediates a consistent activation of BDNF signaling cascades, increased synaptic density, and neuronal survival. These results provide the proof-of-principle on the fabrication process of micropatterned PCL devices, which represent a promising therapeutic option to enhance neuronal regeneration after lesion and for neural tissue engineering and prosthetics.

Abstract
BACKGROUND KRAS mutations are prevalent in non-small cell lung cancer (NSCLC) but its clinical implications remain to be determined. Continual profiling of KRAS mutations in patients is challenging, and the study aims to determine the potential use of urinary DNA in disease predictions. METHODS A total of 150 patients were recruited. To ascertain the clinical relevance of urinary DNA, matched tumor profiles were analyzed. Serial measurements were taken to gauge the reliability of the assay. These results were correlated to overall survival using the Kaplan-Meier estimate. RESULTS A good overall concordance of 93% (consolidated results from serial measurements) was achieved between tumor tissue and urinary DNA profiling. Of the discordant KRAS cases, we observed subsequent positive detection during monitoring and very low concentrations of mutant DNA. In addition, we noted that KRAS-positive patients detected using urinary DNA have good prognostic utility. Interestingly, we also observed that the trend is highly correlative of the rate of change in KRAS mutant DNA concentrations and the period of monitoring. CONCLUSIONS Urinary DNA offered a non-invasive approach to probe NSCLC dynamics, and in our study we showed that it had predictive capabilities for KRAS-positive patients. Serial monitoring of urinary samples showed that it had a predictive role in identifying patients with worse outcome.

Abstract
BACKGROUND Transmission of microbes in the hospital environment occurs frequently through human interactions with high-touch surfaces such as patient beds and over-bed tables. Although stringent cleaning routines are implemented as a preventive measure to minimize transmission of microbes, it is desirable to have high-touch surfaces made of antimicrobial materials. Physical texturing of solid surfaces offers a non-bactericidal approach to control the colonization of such surfaces by microbes. AIM To investigate the efficacy of micro-textured polycarbonate films in reducing bacterial load on over-bed tables in a hospital ward. METHODS Two different micro-patterns were fabricated on polycarbonate film via a thermal imprinting method. Micro-textured films were then mounted on patient over-bed tables in a general hospital ward and the bacterial load monitored over 24 h. Total colony counts, which represented on-specific bacterial loading, and meticillin-resistant Staphylococcus aureus counts were monitored at each time-point. FINDINGS Over a period of 24 h, both micro-textured surfaces showed consistently lower bacterial load as compared to the unpatterned polycarbonate and the bare over-bed table laminate. This study supports the findings of earlier laboratory-scale studies that microscale physical texturing can reduce bacterial colonization on a solid surface. CONCLUSION Results of the current study suggest that micro-textured surfaces could provide a viable method for reducing microbial contamination of high-touch surfaces in hospitals.

Abstract
BACKGROUND AND AIMS Both low birthweight and high birthweight have been associated with the development of cardiometabolic disease in adulthood, possibly reflecting the effect of intrauterine fetal programming. As developmental programming can begin before conception, pre-gravid factors that predict birthweight may be relevant in this context. However, little is known about such factors. Thus, we established a pre-conception cohort to identify maternal pre-gravid cardiometabolic determinants of infant birthweight. METHODS AND RESULTS In this prospective observational cohort study, 1484 newly-married women in Liuyang, China, underwent baseline (pre-gravid) evaluation and then were followed across a subsequent pregnancy. Pre-gravid cardiometabolic characterization consisted of clinical (anthropometry, blood pressure) and biochemical evaluation (total/LDL/HDL cholesterol, triglycerides, glucose) at median 20 weeks before a singleton pregnancy. Mean birthweight was 3294 ± 444 g, with 173 neonates large-for-gestational-age (LGA) and 110 small-for-gestational-age (SGA). On multiple linear regression analysis, positive determinants of birthweight were maternal age, pre-gravid body mass index (BMI), weight gain in pregnancy, length of gestation, and male infant (all p ≤ 0.0003). On logistic regression analysis, independent predictors of an LGA delivery were maternal age (OR = 1.10 per year, 95%CI 1.03-1.18), pre-gravid BMI (OR = 1.21 per kg/m2, 1.07-1.37), and gestational weight gain (OR = 1.10 per kg, 1.06-1.14). The only independent predictor of SGA was gestational weight gain (OR = 0.93 per kg, 0.89-0.97). CONCLUSION Maternal weight before and during pregnancy is the predominant cardiometabolic determinant of infant birthweight, rather than pre-gravid blood pressure, glucose or lipid profile.

Abstract
Aggregate data model‐based meta‐analysis is a regression approach to compare the dose–response and/or time‐course across different treatments using summary level data from the literature. Literature search and systematic review following the Cochrane approach yielded 912 sources for investigational and approved treatments for psoriasis. In addition, data for tofacitinib were obtained from an internal database. Tofacitinib is an oral Janus kinase inhibitor. Two mathematical models were developed for Psoriasis Area and Severity Index (PASI) response in moderate to severe psoriasis patients to quantify the time to maximum effect for PASI75 and to evaluate the dose–response relationship for PASI responders (PASI50, PASI75, PASI90, PASI100) at Week 12. Body weight exhibited an inverse effect on the placebo component of both models, suggesting that body weight affects the overall PASI response regardless of drug. This analysis provides a quantitative framework for efficacy comparisons across psoriasis treatments.

Abstract
Tofacitinib is an oral Janus kinase inhibitor. An integrated analysis was conducted to evaluate dosage optimality for tofacitinib in patients with moderate‐to‐severe plaque psoriasis and the impact of body weight on optimality in this patient population. Data were pooled from one phase IIb trial (2, 5, and 15 mg twice daily (b.i.d.)) and four phase III trials (5 and 10 mg b.i.d.). A longitudinal exposure–response model for Psoriasis Area and Severity Index (PASI) improvement (percent change from baseline) was established. Body weight influenced potency; heavier subjects require higher doses to achieve comparable benefit to lighter subjects. Disease severity, sex, and prior biologic usage were also predictive of response. The 10 and 5 mg doses were predicted to achieve 81% and 65%, respectively, of the maximum effect based on a 75% improvement in PASI. The greater efficacy of 10 mg over 5 mg was clinically meaningful.

Abstract
Abstract
In this study, 422 female patients who presented with clinical indications and underwent ultrasound (US), mammography (MMG), and breast specific gamma imaging (BSGI) before surgery during the period from July 2013 to June 2015 were retrospectively reviewed. Twenty-two of the patients had no pathological report available and were excluded. These patients who presented with clinical indications underwent both ultrasound and mammographic examinations initially. If both US and MMG were positive, the patient was recommended for a BSGI examination for pre-surgical planning. A BSGI examination was also recommended for patients with negative or indeterminate mammographic findings.
The diagnostic results were compared with histological examination and the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for each modality were determined. Combinations of either two or three of the diagnostic results were also reviewed and the corresponding diagnostic indicators calculated. For these combinations, a positive indication on one of the two (or three) diagnostic tests were interpreted as a positive result. The sensitivity of US, MMG, BSGI, the combination of US and MMG, US and BSGI, MMG and BSGI, and the combination of all three together in the diagnosis of breast carcinoma were determined for the 400 patients included in the study and are listed in Table 1, column 1. The specificity, PPV, and NPV for each of these modalities and combinations of modalities were also determined and are shown Table 1, column 2-4.
Table 1 SensitivitySpecificityPPVNPVUS61.389.289.759.8MMG67.594.394.765.2BSGI83.187.991.477.1US & MMG86.884.789.880.6US & BSGI91.382.889.186.1MMG & BSGI92.283.489.585.6US & MMG & BSGI97.579.087.895.4
The population was comprised of 243 patients with 245 malignant lesions and 157 patients with 189 benign lesions. The malignant lesions were primarily infiltrating ductal carcinoma (76%) and ductal carcinoma in situ (14%), with the remaining lesions (10%) being invasive lobular carcinoma, Paget's disease and mixed carcinomas. The benign lesions were primarily fibroadenoma (39%), adenosis (40%) and papilloma (10%), with the remaining lesions (11%) being duct ectasia, inflammation or phyllodes. There were 79 false negative cases by MMG, however, when ultrasound and BSGI were combined, 73 out of 79 were accurately identified. Additionally, there were nine, seventeen and eighteen Ductal Carcinoma in situ (DCIS) misdiagnosed by BSGI, MMG, and ultrasound respectively, but through joint imaging of BSGI+MMG+US; 33 out of 35 were accurately judged.
BSGI is a useful adjunct modality for the diagnosis of breast carcinoma. It is also extremely useful for diagnosis of non-calcified DCIS, and circumvents limitations of mammography in identifying malignant lesion in dense breast. Moreover, it is helpful for improving the diagnosis accuracy of breast carcinoma when BSGI is combined together with MMG and US.

Abstract
OBJECTIVE To investigate the difference of fatty acid content and types between red peanuts and white peanuts. METHODS After being hydrolyzed, extracted, and methyl-esterificated, fatty acid in the sample were separated with the chromatographic column HP-88( 100 m × 0. 25 mm × 0. 20 μm) and analyzed by gas chromatography-mass spectrometry( GC-MS) method. Meanwhile, t-test and rank sum test will be carried on to analyze the determination results of fatty acid in both red and white peanuts growing in Shenzhen, Qingyuan and other four areas. RESULTS The standard curves of fatty acid methyl ester hold good linearity( R~2> 0. 9980) in 0. 2- 10 mg / L, with the recovery between 92. 3% and 118. 8% and relative standard deviation( RSD) between 1. 64% and 7. 70%. Those two peanuts contained 21 fatty acids, such as oleic acid, linoleic acid, palmitic acid, stearic acid and behenic acid. The total fat content in peanuts were between 42. 5% and 50. 6%. After statistical analysis, the differences were not statistically significant. CONCLUSION The method can quickly and sensitively detect fatty acids inpeanuts. Same species and similar content of the fatty acids are in these two peanuts particularly.

Abstract
INTRODUCTION Although gender differences in morbidity and mortality have been measured in patients with moderate to severe burn injury, little attention has been directed at gender effects on health-related quality of life (HRQoL) following burn injury. The current study was therefore conducted to prospectively measure changes in HRQoL for males and females in a sample of burn patients. METHODS A total of 114 adults who received treatment at a statewide burns service for a sustained burns injury participated in this study. Instruments measuring generic health status (Short Form 36 Medical Outcomes Survey version 2), burn-specific HRQoL (Burns Specific Health Scale-Brief), psychological distress (Kessler Psychological Distress Scale) and alcohol use (Alcohol Use Disorders Identification Tool) were prospectively measured at 3, 6 and 12 months post-burn. RESULTS In the 12 months post-injury, female patients showed overall poorer physical (p=0.01) and mental health status (p<0.001), greater psychological distress (p<0.001), and greater difficulty with aspects of burn-specific HRQoL: body image (p<0.001), affect (p<0.001), interpersonal functioning (p=0.005), heat sensitivity (p=0.01) and treatment regime (p=0.01). While significant interaction effects suggested that female patients had more improvement in difficulties with treatment regime (p=0.007), female patients continued to report greater difficulty with multiple aspects of physical and psychosocial health status 12 months post-injury. CONCLUSION Even though demographic variables, injury characteristics and burn care interventions were similar across genders, following burn injury female patients reported greater impairments in generic and burn-specific HRQoL along with psychological morbidity, when compared to male patients. Urgent clinical and research attention utilising an evidence-based research framework, which incorporates the use of larger sample sizes, the use of validated instruments to measure appropriate outcomes, and a commitment to monitoring long-term care, can only improve burn-care.

Abstract
Mass spectrometry-based proteomics has experienced an unprecedented advance in comprehensive analysis of proteins and posttranslational modifications, with particular technical progress in liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) and isobaric labeling multiplexing capacity. Here, we introduce a deep proteomics profiling protocol that combines 10-plex tandem mass tag (TMT) labeling with an optimized LC-MS/MS platform to quantitate whole proteome and phosphoproteome. The major steps include protein extraction and digestion, TMT labeling, two-dimensional liquid chromatography, TiO2-mediated phosphopeptide enrichment, high-resolution mass spectrometry, and computational data processing. This protocol routinely leads to confident quantification of more than 10,000 proteins and approximately 30,000 phosphosites in mammalian samples. Quality control steps are implemented for troubleshooting and evaluating experimental variation. Such a multiplexed robust method provides a powerful tool for dissecting proteomic signatures at the systems level in a variety of complex samples, ranging from cell culture, animal tissues to human clinical specimens.

Abstract
BACKGROUND Anxiety and depression are common in multiple sclerosis (MS). We evaluated the prevalence and factors associated with anxiety, depression and fatigue at the 5-year review of a longitudinal cohort study following a first clinical diagnosis of CNS demyelination (FCD). METHODS Cases with a FCD were recruited soon after diagnosis and followed annually thereafter. A variety of environmental, behavioural and clinical covariates were measured at five-year review. Anxiety and depression were measured using the Hospital Anxiety & Depression Scale (HADS), and fatigue by the Fatigue Severity Scale (FSS). RESULTS Of the 236 cases, 40.2% had clinical anxiety (median HADS-A: 6.0), 16.0% had clinical depression (median HADS-D: 3.0), and 41.3% had clinical fatigue (median FSS: 4.56). The co-occurrence of all three symptoms was 3.76 times greater than expectation. Younger age, higher disability, concussion or other disease diagnosis were independently associated with a higher anxiety score; male sex, higher disability, being unemployed, less physical activity, and antidepressant and/or anxiolytic-sedative medication use were independently associated with a higher depression score. Higher disability, immunomodulatory medication use, other disease diagnosis and anxiolytic-sedative medication use were independently associated with having fatigue, while female sex, higher BMI, having had a concussion, being unemployed and higher disability were associated with a higher fatigue score. CONCLUSION These results support previous findings of the commonality of anxiety, depression and fatigue in established MS and extend this to post-FCD and early MS cases. The clustering of the three symptoms indicates that they may share common antecedents.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a hepatic presentation of obesity and metabolic syndrome. MicroRNA 26a (Mir-26a) has been reported to play functions in cellular differentiation, cell growth, cell apoptosis and metastasis. A recent paper indicated that Mir-26a regulated insulin sensitivity and metabolism of glucose and lipids. However, the role of Mir-26a in NAFLD still needs to be investigated further. In our current study, vectors encoding pre-Mir-26a (LV-26a) and an empty lentiviral vector (LV-Con) delivered approximately 2 × 107 transforming units of recombinant lentivirus were injected into mice through the tail vein. LV-26a-infected mice were protected from glucose dysmetabolism and showed markedly decreased total liver weight, hepatic triglyceride deposition and serum alanine transaminase (ALT) concentration when compared with LV-Con-treated mice. LV-26a-treated mice also exhibited decreased infiltration of immune cells in the liver - something attributed to reduce infiltration of T cell receptor (TCR)-γδ+ , granulocyte-differentiation antigen-1 (Gr-1)+ cells and CD11b+ cells. Next, we found that Mir-26a inhibited the expression of interleukin (IL)-17 and IL-6 in vivo and in vitro. Furthermore, the decreased expression of IL-17 in the liver tissue induced by Mir-26a was abrogated completely by IL-6 overexpression. The decreased total liver weight, hepatic triglyceride deposition and serum ALT concentration induced by Mir-26a was also abrogated completely by IL-6 over-expression. In conclusion, the Mir-26a-IL-6-IL-17 axis regulates the development of NAFLD in a murine model.

Abstract
BACKGROUND Tofacitinib is an oral Janus kinase inhibitor being investigated for psoriasis. A Phase 3 withdrawal/re-treatment study (NCT01186744; OPT Retreatment) showed tofacitinib re-treatment was effective in patients with chronic plaque psoriasis. OBJECTIVES To describe the effects of tofacitinib withdrawal/re-treatment on health-related quality of life (HRQoL) and disease symptoms measured by patient-reported outcomes (PROs). METHODS The study was divided into initial treatment, treatment withdrawal, and re-treatment periods. Initial treatment: patients were randomized to receive tofacitinib 5 (n = 331) or 10 mg (n = 335) BID for 24 weeks. Treatment withdrawal: patients who achieved both ≥ 75% reduction in Psoriasis Area and Severity Index (PASI) score from baseline and Physician's Global Assessment of 'clear'/'almost clear' at Week (W)24 received placebo (withdrawal) or the previous dose (continuous treatment). Re-treatment: at relapse (> 50% loss of W24 PASI response) or at W40, patients received their initial tofacitinib dose. PROs included: Dermatology Life Quality Index (DLQI), Itch Severity Item (ISI), Short Form-36 (SF-36) and Patient's Global Assessment (PtGA). RESULTS After initial treatment with tofacitinib 5 and 10 mg BID, substantial and significant improvements were reported for mean DLQI (baseline: 12.6 and 12.6; W24: 5.1 and 2.6) and ISI (baseline: 6.7 and 6.9; W24: 2.9 and 1.6). Patients continuously treated with tofacitinib 5 and 10 mg BID maintained those improvements through Week 56 (DLQI: 3.0 and 2.1; ISI: 2.3 and 1.4). By W40, patients withdrawn from tofacitinib 5 and 10 mg BID showed worsening in DLQI (5.0 and 6.2) and ISI (3.7 and 4.0) scores; improvements were regained upon re-treatment (W56, DLQI: 3.4 and 2.4; ISI: 2.2 and 1.6). Similar results were reported for PtGA and SF-36. CONCLUSION Continuous tofacitinib treatment provided sustained improvement in HRQoL and disease symptoms. Patients randomized to treatment withdrawal lost initial improvements. Upon re-treatment, improvements were recaptured to levels comparable to those seen with continuous treatment.
