Abstract
BACKGROUND There has been significant interest in pre-cooked noodles that have a long shelf life and are convenient to cook. However, the thermal processes during preparation, and their high moisture content, can lead to significant quality deterioration during storage. Nevertheless, a comprehensive evaluation of these quality losses has not yet been conducted. RESULTS The effects of different storage temperatures (25, 4, and -20 °C) on the retrogradation-related physicochemical changes in pre-cooked rice noodles were elucidated mainly from the water dynamics and structural viewpoints. Thermal analysis demonstrated that amylopectin recrystallization took place in the noodles stored at refrigerated temperature, followed by room temperature. The refrigerated storage accelerated the starch retrogradation that caused the water molecules to become entrapped within the crystalline structure by lowering the water hydration properties and weighted T2 relaxation times of the pre-cooked noodles. These water mobility patterns were correlated with the textural changes in the noodles (greater hardness and Rmax /extensibility). Furthermore, the higher structural density and thickness derived from starch retrogradation were observed in the tomographic and microscopic images of the refrigerated noodles. The principal component analysis demonstrated that various physicochemical changes of the pre-cooked noodles during storage showed high correlations with the degree of starch retrogradation (r > 0.83). CONCLUSION The physicochemical features of the precooked noodles stored under refrigerated conditions were involved in the molecular dynamics of water, showing a notable water mobility reduction derived from the starch retrogradation, which contributed to their thermal, tomographical, and textural changes. © 2023 Society of Chemical Industry.

Abstract
In this study, the effect of high pressure (HP) pretreatment on the stability of pork loins during supercooling (SC) preservation was investigated, and the freshness and postmortem metabolism of pork loins preserved by SC was evaluated. Based on the differential scanning calorimetry (DSC), the peak enthalpies of 200 MPa treatment were lower than those of 50 MPa treatment (P < 0.05). For the nuclear magnetic resonance (NMR) relaxometry, extramyofibrillar water in pork loins was decreased with increasing intermyofibrillar water at >100 MPa (P < 0.05). Compared to unpressurized control all HP treatment had less α-helix structure while random coil was dominated from the Fourier transform infrared (FTIR) spectroscopy (P < 0.05). A 200 MPa was selected to estimate the relationship between HP pretreatment and stability of SC preservation of pork loins. The HP-treated pork loins showed high stability during SC preservation under the relatively low temperature algorithm. Compared to fresh control, HP pretreatment caused physicochemical changes of pork loins which did not recover even after 2 weeks of preservation. Nevertheless, HP followed by SC preservation was able to reduce property changes better than pork loins preserved by normal refrigeration. According to the analyses of transmission electron microscopy (TEM), the HP pretreatment influenced the postmortem biochemical metabolism of pork loins, however, it did not affect the freshness and quality parameters of pork loins due to the subsequently applied low preservation temperature of SC. Therefore, this study demonstrated that moderate HP pretreatment was a potential pretreatment for SC preservation of pork loins.

Abstract
The effects of different sweeteners on the physicochemical properties of soft wheat flour were investigated mainly in terms of thermal, rheological, and water mobility features, and their feasibilities as an alternative to sugar were evaluated in the cookie system. Kestose significantly reduced the solvent retention capacity of wheat flour, followed by sucrose, fructose, and allulose. Thermal analysis showed that the sucrose and kestose distinctly led to an increase in the gelatinization temperature of wheat flour, which was explained by lower T2 relaxation times. In addition, the pasting viscosities and thermo-mechanical properties of wheat flour containing kestose became lower compared to allulose, and these differences were morphologically confirmed by the real-time microscopic measurements during heating. Furthermore, when the sweeteners were incorporated into the cookie formulations, kestose played a positive role as a sugar replacer in the cookie system by presenting a comparable spread factor, texture, and color to cookies with sucrose.

Abstract
BACKGROUND Methylcellulose has been applied as a primary binding agent to control the quality attributes of plant-based meat analogues. H owever, a great deal of effort has been made to search for hydrocolloids to replace methylcellulose because of increasing awareness of clean labels. In this study, a machine learning framework was proposed in order to describe and predict the flow behavior of six hydrocolloid solutions, and the predicted viscosities were correlated with the textural features of their corresponding plant-based meat analogues. RESULTS Different shear-thinning and Newtonian behaviors were observed depending on the type of hydrocolloid and the shear rate. Methylcellulose exhibited an increasing viscosity pattern with increasing temperature, compared to the other hydrocolloids. The machine learning algorithms (random forest and multilayer perceptron models) showed a better viscosity fitting performance than the constitutive equations (power law and Cross models). In addition, three hyperparameters of the multilayer perceptron model (optimizer, learning rate, and the number of hidden layers) were tuned using the Bayesian optimization algorithm. CONCLUSION The optimized multilayer perceptron model exhibited superior performance in viscosity prediction (R2 = 0.9944-0.9961/RMSE = 0.0545-0.0708). Furthermore, the machine learning-predicted viscosities overall showed similar patterns to the textural parameters of the meat analogues. © 2024 Society of Chemical Industry.

Abstract
BACKGROUND A growing body of data suggests that balance impairment may be linked to the onset of dementia. OBJECTIVES However, a large-scale epidemiologic investigation is needed to clarify its association in older adults. DESIGN A retrospective-prospective hybrid database. SETTING Cox proportional hazards regression model was used to assess the relationship between balance impairment and the risk of incident dementia, and the results were provided as adjusted hazard ratios (aHR) with 95% confidence intervals (CI). All participants were tracked until the date of incident dementia, death, or 31 December 2019 whichever came first. PARTICIPANTS We analyzed 143,788 older adults who had at least one health screening between 2009 and 2019 from the Korea National Health Insurance Service-Senior Cohort. MEASUREMENTS A total of 3,774 cases of dementia were discovered throughout 850,425 person-years of follow-up investigation. Balance impairment was associated with a risk of dementia compared to those without balance impairment (adjusted hazard ratio [aHR] 1.83; 95% CI, 1.69-2.00; P value <0.001). RESULTS Risks of the Alzheimer's disease (aHR, 1.80; 95% CI, 1.65-1.96; P for trend <0.001) and the vascular dementia (aHR, 2.94; 95% CI, 1.89-4.58; P for trend <0.001) showed comparable trends and findings. CONCLUSIONS Balance impairment was found to be independently associated with an increased risk of dementia in older adults.

Abstract
Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest-energy events thought to come from extragalactic sources. Their arrival is infrequent, so detection requires instruments with large collecting areas. In this work, we report the detection of an extremely energetic particle recorded by the surface detector array of the Telescope Array experiment. We calculate the particle's energy as [Formula: see text] (~40 joules). Its arrival direction points back to a void in the large-scale structure of the Universe. Possible explanations include a large deflection by the foreground magnetic field, an unidentified source in the local extragalactic neighborhood, or an incomplete knowledge of particle physics.

Abstract
PURPOSE/OBJECTIVE(S) To predict CRT response in locally advanced cervical cancer (LACC) with handcrafted radiomics (HCR) and deep learning radiomics (DLR) using pretreatment MRI. Furthermore, we investigate whether the incorporation of clinical factors improves prediction performance. MATERIALS/METHODS Two hundred and fifty-two patients with LACC are enrolled. All patients are treated with external beam radiotherapy, followed by high-dose-rate intracavitary brachytherapy with concurrent cisplatin. The patients are randomly divided into two independent groups for the training (167 patients) and test datasets (85 patients). Contrast-enhanced T1- and T2-weighted MR scans are obtained. Patients in the training and test sets have similar characteristics in terms of age, tumor size, FIGO stage, HPV infection status, or CRT response. For HCR analysis, 1890 imaging features are extracted and a support vector machine classifier with a five-fold cross-validation is trained using training dataset to predict CRT response and validated using test dataset. For DLR analysis, a 3-dimensional convolutional neural network was trained and validated using test dataset. RESULTS A comparison of the DLR and HCR models reveals that the DLR model exhibits better prediction performance than the HCR model for the test dataset (AUC = 0.721 vs. 0.597, p = 0.097). The incorporation of clinical factors could improve performance in both DLR and HCR models. CONCLUSION The DLR models outperform the HCR models in predicting CRT responses in patients with LACC. Combining clinical factors and MRI may improve the prediction performance in both HCR and DLR analyses.

Abstract
Global interest in high-protein foods has been rapidly increasing and the gluten-free products are no exceptions. Gluten-free extruded noodles made from rice flour were thus fortified with soy protein concentrate (SPC) (0%, 15%, 30%, and 45% by weight), and the physicochemical properties of the noodles were characterized in terms of tomographical, rheological, and structural features. SPC-rice flour blends showed higher water absorption and swelling power at room temperature with increasing levels of SPC, which were reduced upon heating. The flour blends with high-levels of SPC also had lower pasting viscosities. Thermal analysis showed lower enthalpy values and higher temperatures derived from starch gelatinization. When the SPC-rice flour blends were applied to extruded gluten-free rice noodles, the noodles tomographically showed a dense and compact structure, that could be favorably correlated with their textural changes (increased hardness and reduced extensibility). FTIR analysis presented the structural changes of the noodles containing different levels of SPC by showing higher intensity of protein-related absorption peaks and lower starch peak intensity, which could be associated with the reduced cooking loss. Moreover, there existed two water components with different mobilities in the noodles whose spin-spin relaxation times had a tendency to increase with increasing SPC content. The results obtained from this study provided fundamental insights into the processing performance of protein-rich ingredients in gluten-free extruded noodles, probably promoting the development of a wider variety of protein-fortified gluten-free products.

Abstract
Natural regeneration of degraded reefs relies on the recruitment of larvae to restore populations. Intervention strategies are being developed to enhance this process through aquaculture production of coral larvae and their deployment as spat. Larval settlement relies on cues associated with crustose coralline algae (CCA) that are known to induce attachment and metamorphosis. To understand processes underpinning recruitment, we tested larval settlement responses of 15 coral species, to 15 species of CCA from the Great Barrier Reef (GBR). CCA in the family Lithophyllaceae were overall the best inducer across most coral species, with Titanoderma cf. tessellatum being the most effective species that induced at least 50% settlement in 14 of the coral species (mean 81%). Taxonomic level associations were found, with species of Porolithon inducing high settlement in the genus Acropora; while a previously understudied CCA, Sporolithon sp., was a strong inducer for the Lobophyllidae. Habitat-specific associations were detected, with CCA collected from similar light environment as the coral inducing higher levels of settlement. This study revealed the intimate relationships between coral larvae and CCA and provides optimal coral-algal species pairings that could be utilized to increase the success of larval settlement to generate healthy spat for reef restoration.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis (AIH) has been well characterised and codified through the development of diagnostic criteria. These criteria have been adapted and simplified and are widely used in clinical practice. However, there is a need to update and precisely define the criteria for both treatment response and treatment. METHODS A systematic review was performed and a modified Delphi consensus process was used to identify and redefine the response criteria in autoimmune hepatitis. RESULTS The consensus process initiated by the International Autoimmune Hepatitis Group proposes that the term 'complete biochemical response' defined as 'normalization of serum transaminases and IgG below the upper limit of normal' be adopted to include a time point at 6 months after initiation of treatment. An insufficient response by 6 months was a failure to meet the above definition. Non-response was defined as '<50% decrease of serum transaminases within 4 weeks after initiation of treatment'. Remission is defined as liver histology with a Hepatitis Activity Index <4/18. Intolerance to treatment was agreed to stand for 'any adverse event possibly related to treatment leading to potential drug discontinuation'. CONCLUSIONS These definitions provide a simple and reproducible framework to define treatment response and non-response, irrespective of the therapeutic intervention. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable inter-study comparisons. Future prospective database studies are needed to validate these endpoints. LAY SUMMARY Consensus among international experts on response criteria and endpoints in autoimmune hepatitis is lacking. A consensus on endpoints is urgently required to set a global standard for the reporting of study results and to enable the comparison of results between clinical trials. Therefore, the International Autoimmune Hepatitis Group (IAIHG) herein presents a statement on 5 agreed response criteria and endpoints: complete biochemical response, insufficient response, non-response, remission, and intolerance to treatment, which can be used to guide future reporting.

Abstract
BACKGROUND Negative impressions toward fried foods are prevalent due to their high oil absorption and caloric values. A great deal of effort has been thus made to reduce the oil uptake of fried foods. In this study, the effect of wheat and brown rice flour blends on the oil uptake of frying batters was elucidated in terms of rheology and surface roughness. RESULTS The blends with higher proportions of brown rice flour had higher values of pasting parameters and also exhibited a more elastic nature. When a food matrix was deep-fat-fried with frying batters made from wheat and brown rice flour blends, the oil uptake was significantly reduced by 28% compared to wheat flour batter. Based on imaging analysis, the surface properties of the fried crusts were quantitatively measured, demonstrating that the degree of surface roughness distinctly became lower with increasing levels of brown rice flour. Furthermore, the surface roughness parameters (Ra and Rq ) had a strong relationship with the reduced oil uptake. Also, a high proportion of brown rice flour in the blends produced fried samples with a firmer and crispy texture. CONCLUSIONS A reduced oil uptake of batter-coated fried foods was distinctly observed with increasing levels of brown rice flour in the blends and well correlated with the degree of surface roughness (R2 > 0.85). © 2021 Society of Chemical Industry.

Abstract
An AFF is a form of stress fracture induced by excessive physiologic repetitive stress over the bone remodeling capacity. Although glucocorticoid administration is a known risk factor for AFF, no case of AFF with glucocorticoid administration as the only risk factor has been previously reported. In this report, we aimed to highlight the risk of AFF associated with long-term administration of glucocorticoids, and the importance of surveillance and correction of risk factors in patients undergoing long-term glucocorticoid therapy. A 58-year-old male patient was diagnosed with subtrochanteric AFF. He had no medical history of any condition that might disrupt bone metabolism and no known risk factors for AFF, except for long-term administration of glucocorticoid. After fixation of the fracture, the glucocorticoid was replaced with an alternative medication. Although AFF is notorious for delayed union or nonunion, complete union of the fracture was obtained at 14 months postoperatively. This case brought to our attention the possibility that glucocorticoids alone may be responsible for inducing AFF and highlighted the importance of regular assessments in case of necessity of glucocorticoid administration. Additionally, correction of risk factors might expedite the union of AFF.

Abstract
Canola oil was structured into oleogels with different amounts of carnauba wax, and their processing performances were assessed as an alternative to solid fat for imitation cheese low in saturated fat. The contents of solid fat in the oleogels were less vulnerable to the change in temperature than the palm oil. The replacement of palm oil with oleogels produced cheese samples with harder and more cohesive/chewy textures. Dynamic and transient viscoelastic measurements demonstrated that the use of oleogels was effective in increasing the elastic nature of the cheeses. Two distinct components with different proton mobilities were observed in the imitation cheeses, and longer T2 relaxation times were detected in the oleogel samples. The meltability of the cheese with palm oil was not significantly different from those with 3% and 6% oleogels. The saturated fat level of the oleogel cheese was significantly reduced from 45.70 to 5.20%. The application of canola oil-carnauba wax oleogels could successfully produce imitation cheese high in unsaturated fat and low in saturated fat. This study thus demonstrated that the health-functional properties of imitation cheese could be enhanced by using oleogels.

Abstract
OBJECTIVE To examine whether age-specific prevalence of frailty in Japan changed between 2012 and 2017. DESIGN This study performed meta-analyses of data collected from 2012 to 2017 using the Integrated Longitudinal Studies on Aging in Japan (ILSA-J), a collection of representative Japanese cohort studies. SETTING The ILSA-J studies were conducted on community-living older adults. PARTICIPANTS ILSA-J studies were considered eligible for analysis if they assessed physical frailty status and presence of frailty in the sample. Seven studies were analyzed for 2012 (±1 year; n = 10312) and eight studies were analyzed for 2017 (±1 year; n = 7010). Five studies were analyzed for both 2012 and 2017. MEASUREMENTS The study assessed the prevalence of frailty and frailty status according to 5 criteria: slowness, weakness, low activity, exhaustion, and weight loss. RESULTS The overall prevalence of physical frailty was 7.0% in 2012 and 5.3% in 2017. The prevalence of frailty, especially in people 70 years and older, tended to decrease in 2017 compared to 2012. Slight decreases were found in the prevalence of frailty subitems including weight loss, slowness, exhaustion, and low activity between 2012 and 2017, but change in the prevalence of weakness was weaker than other components. CONCLUSIONS The prevalence of physical frailty decreased from 2012 to 2017. There are age- and gender-related variations in the decrease of each component of frailty.

Abstract
Combination of oleogelators has recently started to receive scientific attention since single oleogelator may not adequately compensate for the diverse roles of solid fat in a complicated food system. In this study, grapeseed oil oleogels were prepared with candelilla wax (CDW) and glyceryl monostearate (GMS) blends at varying mass ratios (100:0, 75:25, 50:50, 25:75, and 0:100 [w/w]), and their physicochemical characteristics were characterized in terms of thermal, rheological, and microstructural properties. The oleogel with CDW and GMS at a blending ratio of 75 and 25 (CDW-75:GMS-25) exhibited the lowest melting point, implying a eutectic behavior. The CDW-75:GMS-25 oleogel also had a harder texture, greater viscoelasticity, and lower oiling-off characteristics that were highly attributed to its small crystals and dense structural network observed from phase-contrast microscopic images. When GMS from different vendors were examined for melting behavior and hardness of oleogels, it was found that the oleogel properties were highly dependent on the detailed composition of GMS. NMR study showed that the ternary system of CDW, glyceryl 1-monostearate, and glyceryl 1,3-distearate was responsible for the eutectic behavior of the CDW-75:GMS-25 oleogel. This study reports the unique and improved melting and physical properties of oleogels with the mixture of CDW and GMS, which can increase the feasibility of the oleogel technology in actual food products. However, caution should be taken in selecting the oleogelators because their detailed composition and properties can vary depending on sources and processing conditions. PRACTICAL APPLICATION: Increasing attention has been paid to the combination of oleogelators since single oleogelator may not adequately compensate for the diverse roles of solid fat in a complicated food system. This study showed new eutectic characteristics at a specific blending ratio of candelilla wax and glyceryl monostearate that could be positively correlated with the increased hardness, viscoelasticity, and oiling-off features. The results may encourage the food industry to utilize this binary oleogelator blend as an alternative to solid fat high in saturated fat by providing new functional properties.

Abstract
Background:Heart failure is a prevalent and ever-increasing public health concern associated with significant morbidity, mortality, and financial burden. Therefore, identifying any factors that worsen the outcome of patients with heart failure is crucial to the nation’s medical and financial health.One of the major comorbidities associated with heart failure is gout. Gout is a clinical syndrome of joint inflammation resulting from the deposition of monosodium urate crystals, causing painful and swollen arthritis. Acute gout flares in the context of acute heart failure (AHF) exacerbations result in longer lengths of stay and form an independent risk factor for increased readmissions or death1. The use of loop diuretics in treating patients with AHF exacerbations may cause new onset of gouty arthritis or recurrence of established gout by increasing serum uric acid levels. Uric acid alone is implicated as an independent predictor of mortality in patients with chronic heart failure2.Objectives:In this study, we aim to better characterize the incidence of acute gout flares in patients being treated with intravenous bumetanide for AHF exacerbations.Methods:This single-center retrospective cohort study included adult patients within an urban tertiary-care center hospital between 5 August 2016 and 30 June 2018. Chart review was performed to identify 130 patients who were hospitalized for AHF exacerbations, received intravenous (IV) bumetanide, and developed an acute gout flare for a total of 176 cases (Figure 1).Figure 1Patient SelectionPatients were identified as having an acute gout flare if the primary treating physician(s) documented a clinical picture congruous with acute gout (e.g., onset of a painful, swollen, or erythematous joint) and administered conventional treatment for acute gout including non-steroidal anti-inflammatory agents (NSAIDs), steroids, colchicine, urate-lowering therapies, and/or intra-articular joint injection with symptomatic improvement.Results:The annualized incidence of acute gout while receiving IV bumetanide for a heart failure exacerbation is 7.17%.There was no statistical difference in age, gender, race, or BMI among patients who developed acute gout compared with those who did not develop acute gout while receiving IV bumetanide.An acute gout flare that occurred during treatment of AHF with IV bumetanide increased hospital length of stay (LOS) by 3 days (mean LOS 15.2 days in those who had acute gout, mean LOS 11.6 days in those who did not [p-value 0.277]).Patients who received allopurinol during their hospitalization for AHF exacerbation had lower 30-day readmission rates for any cause (p-value 0.017, Table 4). There was no reduction in the 30-day readmission rate in patients who received colchicine without allopurinol during their hospitalization for AHF exacerbation. Those with a history of gout had higher readmission rates than those without a history of gout (p-value 0.007).Conclusion:Gout is known to be a weighty contributor to patients’ morbidity and mortality in heart failure, and the occurrence of acute gout flare in AHF exacerbations may be precipitated by the use of loop diuretics. We show that the use of IV bumetanide in patients hospitalized for AHF exacerbations is associated with a 7.17% yearly incidence of acute gout flares. Furthermore, patients with a history of gout were found to have higher readmission rates, and those who received allopurinol during their hospitalization had lower readmission rates.References:[1]Thanassoulis G, Brophy JM, Richard H, Pilote L.

Abstract
Abstract
Background/Introduction
Physical activity has been shown to reduce mortality in a dose-response fashion. Current guidelines recommend 500 to 1,000 MET-min per week of regular physical activity. However, evidence is limited regarding the specific dose-response relationship in patients with cardiovascular disease.
Purpose
Our aim was to compare the impact of physical activity on mortality in primary versus secondary cardiovascular prevention.
Methods
We analyzed 441,798 individuals with complete information on physical activity levels between 2009 and 2015 were extracted from a population-based cohort (National Health Insurance Service-National Health Screening cohort). Physical activity measured by self-report questionnaires. A rating of 2.9, 4.0, and 7.0 METs were assigned for light-intensity, moderate-intensity, and vigorous-intensity activities, respectively. Physical activity-related energy expenditure (MET-min/week) was calculated by summing the product of frequency, intensity, and duration. The level of physical activity was classified into 0, 0 to 499, 500 to 999, 1,000 to 1,499, and ≥1,500 MET-min/week. Study participants were stratified by the presence of cardiovascular disease, defined as prior myocardial infarction, ischemic heart disease, prior stroke, and/or chronic heart failure. The main study outcome was all-cause mortality. The median follow-up duration was 5.9 years.
Results
Individuals with cardiovascular disease had lower physical activity levels and a higher risk of mortality than those without cardiovascular disease. There was an inverse relationship between the physical activity level and the mortality risk in both groups. The benefit in the secondary prevention group was shown to be greater than that in the primary prevention group: every 500 MET-min/week increase in physical activity resulted in a 14% and 7% risk reduction in mortality in the secondary and primary prevention groups, respectively (interaction P<0.001). In addition, while individuals without cardiovascular disease benefited the most between 0 and 500 MET-min/week of physical activity, the benefit in those with cardiovascular disease continued above 500 to 1,000 MET-min/week. The adjusted mortality risk of individuals with cardiovascular disease who performed a high level of physical activity (≥1,000 MET-min/week) was shown to be comparable to or lower than that of their counterparts without cardiovascular disease.
Adjusted risk of mortality
Conclusion
Individuals with cardiovascular disease may benefit from physical activity to a greater extent than do healthy subjects without cardiovascular disease. Clinicians should encourage patients with cardiovascular disease to maintain a physically active lifestyle as much as possible.

Abstract
AIM This study aimed to investigate the association between Twitter exposure and the number of citations for coloproctology articles. METHOD Original articles from journals using Twitter between June 2015 and May 2016 were evaluated for the following characteristics: publishing journal; article subject; study design; nationality, speciality and affiliation of the author(s); and reference on Twitter. Citation data for these articles were retrieved from Google Scholar (https://scholar.google.com) in January 2018. We performed a univariate analysis using these data followed by a multivariate, logistic regression analysis to search for factors associated with a high citation level, which was defined as accrual of more than five citations. RESULTS Out of six coloproctology journals listed on the InCites JCR database, three (Diseases of the Colon & Rectum, Colorectal Disease and Techniques in Coloproctology) used Twitter, where 200 (49.5%) out of a total of 404 articles had been featured. Citation rates of articles that featured on Twitter were significantly higher than those that did not (11.4 ± 9.2 vs 4.1 ± 3.1, P < 0.001). In multivariate analysis, Twitter exposure (OR 8.6, P = 0.001), European Union nationality (OR 2.4, P = 0.004), Colorectal Disease journal (OR 3.3, P = 0.005) and systematic review articles (OR 3.4, P = 0.009) were associated with higher citation levels. CONCLUSION Article exposure on Twitter was strongly associated with a high citation level. Medical communities should encourage journals as well as physicians to actively utilize social media to expedite the spread of new ideas and ultimately benefit medical society as a whole.

Abstract
BACKGROUND While increased levels of circulating inflammatory cytokines in chronologically aged humans have been linked to the development of ageing-associated chronic disorders (e.g., cardiovascular disease, type II diabetes, osteoporosis and Alzheimer's disease), approaches that reduce circulating cytokines are not yet available. In chronologically aged mice, we recently demonstrated that epidermal dysfunction largely accounts for age-associated elevations in circulating cytokine levels, and that improving epidermal function reduced circulating cytokine levels. OBJECTIVE We performed a pilot study to determine whether improving epidermal function reduces circulating pro-inflammatory cytokine levels in aged humans. METHODS Thirty-three aged humans were topically treated twice-daily for 30 days, with ≈ 3 mL of an emollient, previously shown to improve epidermal function, while untreated, aged humans and a cohort of young volunteers served as controls. Changes in epidermal function and levels of three key, age-related, plasma cytokines (IL-1β, IL-6 and TNFα) were measured at baseline and after treatment, using Luminex 200™ system. RESULTS We also found significantly higher baseline levels of IL-1β, IL-6 and TNFα in aged vs. young humans (P < 0.001), as previously reported. Topical applications of the barrier repair emollient significantly enhanced epidermal permeability barrier function (P < 0.01) and stratum corneum hydration (P < 0.05). In parallel, circulating levels of IL-1β and IL-6 normalized, while TNFα levels declined substantially. CONCLUSION The results of this preliminary study suggest that a larger clinical trial should be performed to confirm whether improving epidermal function also can reduce circulating pro-inflammatory cytokine levels in aged humans, while also possibly attenuating the downstream development of chronic inflammatory disorders in the aged humans.

Abstract
Abstract
Purpose
Mammography(MMG) is a measure of screening that is proven to be effective in lowering death rate in breast cancer validated by randomized control trials. Recently, the number of incidence of breast cancer in Korean women is showing ascending tendency, and also as compared to those in North American and European countries, prevalence age tends to be lower. Since they tend to have much dense breast, MMG alone can hardly be considered as a sufficient measure of breast cancer screening.
The purpose of the study is to study the effectiveness of breast ultrasonography(US) in breast cancer screening in Korean women by investigating the ratio of patients who are diagnosed as malignant in breast US over those who are diagnosed as negative or benign(category 1 and 2) and dense breast(category 0) in MMG.
Materials and Methods
We conducted the retrograde study over 2776 female subjects who had undergone screening MMG in single center in South Korea during the period between Jan, 1st 2010 to Dec, 31st 2016. Female patients are categorized according to BI-RAD category. 164 of subjects were previously undergone a breast cancer surgery, which made them eliminated from the list, and 2612 subjects are finally selected.
Results
Some more 33 subjects are excluded from the list and rest 2579 subject had undergone breast US. Among these, 1133 subjects (43.9%, 1133/2579) correspond to dense breast of BI-RADS category 0, while 303 of them are suspected of category 4 or more. The subjects corresponding to category 1 to 3 are 663, 251 and 229 respectively. 307 of 1133 subjects in category 0 are confirmed as having suspicious lesion based on findings of breast US. Among them, 66 subjects are identified as malignant based on biopsy, which accounts for 5.8% (66/1133). 104 subjects in category 1, are confirmed to have lesions based on findings of breast US, where 25 alone were identified as malignant (3.8%, 25/663). Likewise, 10 (4.0%, 10/251) in category 2 and 13 (5.7%, 13/229) in category 3 are identified.

Conclusion
It appears that 43.9% of total 2579 subjects undergone MMG and breast US are confirmed as dense breast in category 0 and 5.8% of them are diagnosed as breast cancer according to breast US and biopsy. Likewise, for those who are considered as either category 1 or 2, which is negative or benign lesion category, 3.8% are diagnosed as breast cancer. As it is appeared in this study, cancer detection can be more effective in parallel measure of MMG and breast US rather than MMG alone, especially for breast cancer screening of Korean female subjects.

Abstract
While therapeutic approaches for psoriasis are widely available, preventive regimens are lacking. We aimed to determine whether improvements in epidermal function could prevent psoriasis relapse. Two self-controlled cohort studies were designed, enrolling two cohorts of patients with psoriasis (n = 30 and n = 60) to be treated topically with an in-house-prepared emollient or ATOPALM® cream applied twice daily to one forearm for 20 and 30 days, respectively, while the same sites on the contralateral arm served as the untreated control. Epidermal function on both arms was assessed prior to and at the end of the trials. Delayed relapse on the treated arm was seen in 54.5% and 71% of patients in the first and second cohort, respectively. The time of psoriatic relapse correlated with the extent of abnormalities in baseline epidermal function. These results suggest that improvements in epidermal function with topical emollients can prevent/attenuate the development of psoriasis.

Abstract
This paper proposes a 2.2 noise efficiency factor (NEF) instrumentation amplifier for neural recording applications. A parametric amplifier based on the MOS C-V characteristic is designed as a pre-amplifier stage, lowering the input referred noise of the following stages by 3.4×. Sampling noise is minimized by oversampling the input signal and switching power is reduced by adopting an 8-phase soft-charging technique.

Abstract
Although surrogate measures to quantify pain intensity have been commercialised, there is a need to develop a new index with improved accuracy. The aim of this study was to develop a new analgesic index using nasal photoplethysmography data. The specially designed sensor was placed between the columella and the nasal septum to acquire nasal photoplethysmography in surgical patients. Nasal photoplethysmography and Surgical Pleth Index® (GE Healthcare) data were obtained for 14 min both in the absence (pre-operatively) or presence (postoperatively) of pain in a group of surgical patients, each patient acting as their own control. Various dynamic photoplethysmography variables were extracted to quantify pain intensity; the most accurate index was selected using logistic regression as a classifier. The area under the curve of the receiver-operating characteristic curve was measured to evaluate the accuracy of final model predictions. In total, 12,012 heart beats from 89 patients were used to develop a new Nasal Photoplethysmography Index for analgesic depth quantification. The two-variable model (a combination of diastolic peak point variation and heart beat interval variation) was most accurate in discriminating between the presence and absence of pain (numerical rating scale (NRS) ≥ 3). The accuracy and area under the curve of the receiver-operating characteristic curve for the Nasal Photoplethysmography Index were 75.3% and 0.8018, respectively, and 64.8% and 0.7034, respectively, for the Surgical Pleth Index. The Nasal Photoplethysmography Index clearly distinguished pain (NRS ≥ 3) in awake surgical patients with postoperative pain. The Nasal Photoplethysmography Index performed better than the Surgical Pleth Index. Further validation studies are needed to evaluate its feasibility to quantify pain intensity during general anaesthesia.

Abstract
The wide geographic spread of Eurasian Goose/Guangdong lineage highly pathogenic avian influenza (HPAI) clade 2.3.4.4 viruses by wild birds is of great concern. In December 2014, an H5N8 HPAI clade 2.3.4.4 Group A (2.3.4.4A) virus was introduced to North America. Long-distance migratory wild aquatic birds between East Asia and North America, such as Northern Pintail (Anas acuta), were strongly suspected of being a source of intercontinental transmission. In this study, we evaluated the pathogenicity, infectivity and transmissibility of an H5N8 HPAI clade 2.3.4.4A virus in Northern Pintails and compared the results to that of an H5N1 HPAI clade 2.3.2.1 virus. All of Northern Pintails infected with either H5N1 or H5N8 virus lacked clinical signs and mortality, but the H5N8 clade 2.3.4.4 virus was more efficient at replicating within and transmitting between Northern Pintails than the H5N1 clade 2.3.2.1 virus. The H5N8-infected birds shed high titre of viruses from oropharynx and cloaca, which in the field supported virus transmission and spread. This study highlights the role of wild waterfowl in the intercontinental spread of some HPAI viruses. Migratory aquatic birds should be carefully monitored for the early detection of H5 clade 2.3.4.4 and other HPAI viruses.
