Abstract
74-year-old woman was diagnosed with locally advanced unresectable transverse colon cancer. She started CAPOX therapy as first-line therapy after ileostomy. After second course, MSI-high was detected, so nivolumab plus ipilimumab combination therapy was started as second-line therapy. After 4 courses of combination therapy, she was judged to be in partial response and surgery was performed. Histopathological diagnosis of the surgical specimen showed complete response, and she is still alive without recurrence 15 months after surgery.

Abstract
A 80s man was diagnosed circulated type 2 colon cancer at the transverse colon, and pathological findings was adenocarcinoma( por1). Genomic findings were microsatellite instability-high(MSI-H), all RAS wild type and BRAFV600E mutated. Contrast-enhanced CT showed an enlarged lymph nodes(#221, #222, #223, #214)along the middle colic and superior mesenteric artery. Clinical diagnosis was a locally advanced unresectable transverse colon cancer, cT4aN3M1a(LYM), cStage Ⅳa. Drug therapy with pembrolizumab was prescribed. Six months later, contrast-enhanced CT and PET demonstrated remarkable shrinkage of the primary tumor and lymph nodes except 2 peri-colic enlarged lymph nodes. Primary lesion turned almost undetectable, however the biopsy demonstrated residual tumor. Two months later, CT showed that the residual lymph nodes had also disappeared.

Abstract
Planets with radii between that of the Earth and Neptune (hereafter referred to as 'sub-Neptunes') are found in close-in orbits around more than half of all Sun-like stars1,2. However, their composition, formation and evolution remain poorly understood3. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for initial conditions and environment. Those in resonance (with their orbital periods related by a ratio of small integers) are particularly valuable because they imply a system architecture practically unchanged since its birth. Here we present the observations of six transiting planets around the bright nearby star HD 110067. We find that the planets follow a chain of resonant orbits. A dynamical study of the innermost planet triplet allowed the prediction and later confirmation of the orbits of the rest of the planets in the system. The six planets are found to be sub-Neptunes with radii ranging from 1.94R⊕ to 2.85R⊕. Three of the planets have measured masses, yielding low bulk densities that suggest the presence of large hydrogen-dominated atmospheres.

Abstract
Several studies conducted in patients with various stages of chronic kidney disease (CKD) have investigated the association of iron status markers, such as transferrin saturation (TSAT) and serum ferritin, with kidney outcomes. However, the associations were inconsistent and remain strongly debated. Therefore, we aimed to investigate whether TSAT and serum ferritin levels were associated with kidney outcome in such a population. In this study, 890 patients who were admitted for the evaluation of and education for CKD were prospectively followed. Primary kidney outcome was a composite of doubling of serum creatinine, end-stage kidney disease, or death due to kidney failure. Participants were divided into quartiles (Q1-Q4) according to TSAT or serum ferritin levels. During a median follow-up period of 2.8 years, kidney events occurred in 358 patients. In the multivariable Cox analyses, compared with Q3 of TSAT, the hazard ratios (95% confidence intervals) for Q1, Q2, and Q4 were 1.20 (0.87, 1.66), 1.38 (1.01, 1.87), and 1.14 (0.82, 1.59), respectively. Compared with Q2 of serum ferritin, lower and higher quartiles had a significantly increased risk for kidney outcome; hazard ratios (95% confidence intervals) for Q1, Q3, and Q4 were 1.64 (1.18, 2.27), 1.71 (1.24, 2.37), and 1.52 (1.10, 2.10), respectively. A Fine-Gray model with death before kidney events as a competing risk showed results similar to the above. In CKD, lower and higher ferritin levels were independent risk factors for kidney disease progression.

Abstract
BACKGROUND The association between serum uric acid (SUA) concentration and kidney outcomes in patients with chronic kidney disease (CKD) is controversial. Furthermore, there are no reports regarding the association of clearance of uric acid (CUA) with kidney outcomes. We aimed to determine whether SUA or CUA was associated with kidney outcomes in patients with CKD stratified by sex. METHODS The present prospective study was conducted in 815 patients (523 men and 292 women) with CKD. The participants were divided into quartiles (Q1-Q4) of SUA or CUA for each sex. Endpoints were defined as a composite of doubling of serum creatinine (SCr), end-stage kidney disease (ESKD), or death (outcome 1) and a composite of doubling of SCr or ESKD (outcome 2). RESULTS During a median follow-up of 2.5 years, outcomes 1 and 2 occurred in 363 and 321 patients, respectively. Multivariable-adjusted Cox analyses showed that in men, the hazard ratios (95% confidence intervals) for outcome 1 of Q1, Q2, and Q3 of CUA were 2.08 (1.18-3.70), 2.03 (1.22-3.39), and 1.85 (1.17-2.95), respectively, compared with Q4. Additionally, there were similar associations between lower CUA quartiles and outcome 2 in men. However, no associations between SUA and either outcome were observed in men. Conversely, in women, neither SUA nor CUA was associated with an outcome. CONCLUSION In CKD, lower CUA was independently associated with poor kidney outcomes only in men, and in both sexes, there was no association of SUA with kidney outcomes.

Abstract
A 70s woman with advanced rectal cancer(AV 3 cm, type 2)was diagnosed as cT3N2M1a, Stage Ⅳ(UICC, TNM 8th) and underwent total neoadjuvant therapy(TNT)consisted of preoperative 5 Gy×5 short course RT followed by 5 courses of CAPOX plus BEV and CAPOX. Post-treatment endoscopy revealed nearCR, MRI failed to identify the primary tumor, and the mesenteric and lateral lymph node enlargement had disappeared. The patient underwent robot-assisted low anterior resection, bilateral lymph node dissection, and temporary ileal colostomy. Postoperative pathological findings were ypT0N0M0, Stage 0, and the efficacy evaluation was TRG 0(AJCC)with no residual tumor including lateral lymph nodes. The patient was discharged on the 16th day without any postoperative complications and is currently alive 6 months postoperatively without recurrence.

Abstract
The patient is a 50s year old man. He visited his local doctor with complaints of anal pain and bloody stools, and a rectal examination revealed a tumor on the anterior wall of the rectal canal. CT imaging showed tumors invading the prostate, urethra, and anorectal muscles, and a 3 mm-sized nodule was found in the lungs. The patient was diagnosed as cT4bN1M1a, Stage Ⅳ, and total neoadjuvant chemotherapy was planned as preoperative treatment. The 5 Gy×5 times radiation therapy followed by 5 courses of CAPOX plus BEV as preoperative chemotherapy and CAPOX. CAPOX was administered. After completion of treatment, the colonoscopy showed PR, and MRI showed clear boundary between the prostate and tumor but invasion into the anorectal muscles; CT showed no lung metastasis, and preoperative diagnosis was ycT4bN0M0, ycStage Ⅱ. Robotic-assisted rectal amputation and left lateral lymph node dissection were performed under general anesthesia. Pathologically, the patient was diagnosed as ycT4bN0M0, Stage Ⅱ, and the efficacy was determined as TRG 1(AJCC). Vertical dissection was negative and radical resection was possible.

Abstract
BACKGROUND Doctors are increasingly expected to demonstrate medical leadership and management (MLM) skills. The Faculty of Medical Leadership and Management (FMLM) has published an indicative undergraduate curriculum to guide the development of MLM content at UK medical schools. METHOD Students from 30 medical schools were surveyed to determine their understanding of MLM teaching at their school. Timetables for 21 schools were searched for MLM-related keywords. Student-reported teaching and timetabled teaching were coded according to predefined themes. Aggregated demographic and postgraduate performance data were obtained through collaboration with the Medical Student Investigators Collaborative (msico.org). RESULTS Whilst 88% of medical students see MLM teaching as relevant, only 18% believe it is well integrated into their curriculum. MLM content represented ∼2% of timetabled teaching in each 5-year undergraduate medical course. Most of this teaching was dedicated to teamwork, performance/reflection and communication skills. There was minimal association between how much of a topic students believed they were taught, and how much they were actually taught. We found no association between the volume of MLM teaching and performance in postgraduate examinations, trainee career destinations or fitness to practice referrals. CONCLUSION Our findings demonstrate limited and variable teaching of MLM content. Delivery was independent of broader teaching and assessment factors.

Abstract
AIM The Controlling Nutritional Status (CONUT) score and the Prognostic Nutritional Index (PNI) reflect the immunonutritional status of patients. However, the associations of these two indices with cardiovascular disease (CVD) have not been characterized in patients with chronic kidney disease (CKD). Therefore, the current study aimed to determine whether the CONUT score or PNI was associated with prior CVD in patients with CKD. METHODS A cross-sectional study of 2,751 patients with CKD who were not on dialysis was performed. The patients were grouped into tertiles (T1-T3) of PNI and placed into three groups following their CONUT score: low- (CONUT score, 0), mild- (CONUT score, 1-2), and moderate-to-high- (CONUT score, ≥ 3) risk groups. RESULTS Prior CVD was present in 655 (24%) of the participants. Multivariable logistic regression analyses, with adjustment for potential confounders, showed that high CONUT score was associated with prior CVD than the low score (mild-risk group: odds ratio [OR]=1.35, 95% confidence interval [CI]=1.04-1.76; moderate-to-high-risk group: OR=1.66, 95% CI=1.19-2.30). In addition, the lower PNI tertiles were independently associated with prior CVD compared with T3 of PNI (T1: OR=1.45, 95% CI=1.09-1.92; T2: OR=1.32, 95% CI=1.01-1.72). CONCLUSIONS Both CONUT score and PNI were found to be independently associated with prior CVD in patients with CKD in the present cross-sectional study. A longitudinal study is needed to elucidate whether these two indices are associated with subsequent cardiovascular events.

Abstract
Plasma renin activity (PRA) is lower in patients with diabetic nephropathy (DN) than in healthy individuals. However, the association, if any, between PRA and renal outcomes in patients with DN remains uncertain. In a 2-year prospective observational study, we aimed to investigate the association of PRA with the decline in kidney function in patients with DN. We studied 97 patients with DN who were categorized according to tertile (T1-T3) of PRA. The annual changes in estimated glomerular filtration rate (eGFR) (mL/min/1.73 m2/year) were determined from the slope of the linear regression curve for eGFR. The secondary endpoint was defined as a composite of the doubling of serum creatinine or end-stage renal disease. Results showed that kidney function rapidly declined with lower tertiles of PRA (median value [interquartile range] of the annual eGFR changes: -8.8 [-18.5 to -4.2] for T1, -8.0 [-14.3 to -3.2] for T2, and -3.1 [-6.3 to -2.0] for T3; p for trend <0.01). Multivariable linear regression analyses showed that, compared with T3, T1 was associated with a larger annual change in eGFR (coefficient, -4.410; 95% confidence interval [CI], -7.910 to -0.909 for T1). Composite renal events occurred in 46 participants. In multivariable Cox analysis, the lower tertiles of PRA (T1 and T2) were associated with higher incidences of the composite renal outcome (T2: hazard ratio [HR], 4.78; 95% CI, 1.64-13.89; T1: HR, 4.85; 95% CI 1.61-14.65) than T3. In conclusion, low PRA is independently associated with poor renal outcomes in patients with DN.

Abstract
BACKGROUND The balance of benefits and harms associated with enteral tube feeding for people with severe dementia is not clear. An increasing number of guidelines highlight the lack of evidenced benefit and potential risks of enteral tube feeding. In some areas of the world, the use of enteral tube feeding is decreasing, and in other areas it is increasing. OBJECTIVES To assess the effectiveness and safety of enteral tube feeding for people with severe dementia who develop problems with eating and swallowing or who have reduced food and fluid intake. SEARCH METHODS We searched ALOIS, the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE, Embase, four other databases and two trials registers on 14 April 2021. SELECTION CRITERIA We included randomised controlled trials (RCTs), or controlled non-randomised studies. Our population of interest was adults of any age with a diagnosis of primary degenerative dementia of any cause, with severe cognitive and functional impairment, and poor nutritional intake. Eligible studies evaluated the effectiveness and complications of enteral tube feeding via a nasogastric or gastrostomy tube, or via jejunal post-pyloric feeding, in comparison with standard care or enhanced standard care, such as an intervention to promote oral intake. Our primary outcomes were survival time, quality of life, and pressure ulcers. DATA COLLECTION AND ANALYSIS Three review authors screened citations and two review authors assessed full texts of potentially eligible studies against inclusion criteria. One review author extracted data, which were then checked independently by a second review author. We used the 'Risk Of Bias In Non-randomised Studies of Interventions' (ROBINS-I) tool to assess the risk of bias in the included studies. Risk of confounding was assessed against a pre-agreed list of key potential confounding variables. Our primary outcomes were survival time, quality of life, and pressure ulcers. Results were not suitable for meta-analysis, so we presented them narratively. We presented results separately for studies of percutaneous endoscopic gastrostomy (PEG) feeding, nasogastric tube feeding and studies using mixed or unspecified enteral tube feeding methods. We used GRADE methods to assess the overall certainty of the evidence related to each outcome for each study. MAIN RESULTS We found no eligible RCTs. We included fourteen controlled, non-randomised studies. All the included studies compared outcomes between groups of people who had been assigned to enteral tube feeding or oral feeding by prior decision of a healthcare professional. Some studies controlled for a range of confounding factors, but there were high or very high risks of bias due to confounding in all studies, and high or critical risks of selection bias in some studies. Four studies with 36,816 participants assessed the effect of PEG feeding on survival time. None found any evidence of effects on survival time (low-certainty evidence). Three of four studies using mixed or unspecified enteral tube feeding methods in 310 participants (227 enteral tube feeding, 83 no enteral tube feeding) found them to be associated with longer survival time. The fourth study (1386 participants: 135 enteral tube feeding, 1251 no enteral tube feeding) found no evidence of an effect. The certainty of this body of evidence is very low. One study of PEG feeding (4421 participants: 1585 PEG, 2836 no enteral tube feeding) found PEG feeding increased the risk of pressure ulcers (moderate-certainty evidence). Two of three studies reported an increase in the number of pressure ulcers in those receiving mixed or unspecified enteral tube feeding (234 participants: 88 enteral tube feeding, 146 no enteral tube feeding). The third study found no effect (very-low certainty evidence). Two studies of nasogastric tube feeding did not report data on survival time or pressure ulcers. None of the included studies assessed quality of life. Only one study, using mixed methods of enteral tube feeding, reported on pain and comfort, finding no difference between groups. In the same study, a higher proportion of carers reported very heavy burden in the enteral tube feeding group compared to no enteral tube feeding. Two studies assessed the effect of nasogastric tube feeding on mortality (236 participants: 144 nasogastric group, 92 no enteral tube feeding). One study of 67 participants (14 nasogastric, 53 no enteral tube feeding) found nasogastric feeding was associated with increased mortality risk. The second study found no difference in mortality between groups. The certainty of this evidence is very low. Results on mortality for those using PEG or mixed methods of enteral tube feeding were mixed and the certainty of evidence was very low. There was some evidence from two studies for enteral tube feeding improving nutritional parameters, but this was very low-certainty evidence. Five studies reported a variety of harm-related outcomes with inconsistent results. The balance of evidence suggested increased risk of pneumonia with enteral tube feeding. None of the included studies assessed behavioural and psychological symptoms of dementia. AUTHORS' CONCLUSIONS We found no evidence that tube feeding improves survival; improves quality of life; reduces pain; reduces mortality; decreases behavioural and psychological symptoms of dementia; leads to better nourishment; improves family or carer outcomes such as depression, anxiety, carer burden, or satisfaction with care; and no indication of harm. We found some evidence that there is a clinically significant risk of pressure ulcers from enteral tube feeding. Future research should focus on better reporting and matching of control and intervention groups, and clearly defined interventions, measuring all the outcomes referred to here.

Abstract
PURPOSE It remains unclear whether subclinical hypothyroidism (SCH) is associated with renal prognosis in patients with chronic kidney disease (CKD). Therefore, we prospectively investigated the association of SCH with renal outcomes in CKD. METHODS We conducted a prospective observational study of 480 euthyroid patients and 89 patients with SCH. The endpoints were defined as a composite of doubling of serum creatinine (SCr), end-stage renal disease (ESRD), or death, and a composite of doubling of SCr or ESRD was added as an alternative outcome. Logistic regression analyses were used to identify the factors associated with SCH. In addition, a Cox proportional hazards model was performed to determine whether SCH was associated with poor renal outcomes. RESULTS During a median follow-up period of 26.1 months, doubling of SCr, ESRD, or death and doubling of SCr or ESRD occurred in 244 and 213 patients, respectively. In univariable logistic regression analyses, SCH was significantly associated with older age, lower hemoglobin, higher proteinuria, lower estimated glomerular filtration rate (eGFR), and higher log B-type natriuretic peptide (BNP). Multivariable Cox analyses showed that SCH was associated with poorer renal outcomes after adjustment for covariates, including eGFR and log BNP [doubling of SCr, ESRD, or death: hazard ratio (HR) 1.61, 95% confidence interval (CI), 1.16-2.23; doubling of SCr or ESRD: HR 1.53, 95% CI 1.07-2.20], compared with euthyroidism. CONCLUSIONS In CKD, SCH is independently associated with poor renal outcomes, suggesting that screening for SCH might be needed to accurately predict renal prognosis.

Abstract
Spectroscopy of transiting exoplanets can be used to investigate their atmospheric properties and habitability. Combining radial velocity (RV) and transit data provides additional information on exoplanet physical properties. We detect a transiting rocky planet with an orbital period of 1.467 days around the nearby red dwarf star Gliese 486. The planet Gliese 486 b is 2.81 Earth masses and 1.31 Earth radii, with uncertainties of 5%, as determined from RV data and photometric light curves. The host star is at a distance of ~8.1 parsecs, has a J-band magnitude of ~7.2, and is observable from both hemispheres of Earth. On the basis of these properties and the planet's short orbital period and high equilibrium temperature, we show that this terrestrial planet is suitable for emission and transit spectroscopy.

Abstract
OBJECTIVE Double-strand (ds) DNA-enveloped viruses can cause oral infection. Our aim is to investigate whether oral mucosal cells participate in immune response against cytosolic dsDNA invasion. METHODS We examined the response to transfected herpes simplex virus (HSV) dsDNA via intracellular receptors in oral keratinocytes (RT7) and fibroblasts (GT1), and the effect of TNF-α on those responses. RESULTS Transfected dsDNA increased CXCL10 expression via NF-κB activation in both cell types, while those responses were inhibited by knockdown of RIG-I, an RNA sensor. Although IFI16, a DNA sensor, was expressed in the nuclei of both types, its knockdown decreased transfected dsDNA-induced CXCL10 expression in GT1 but not RT7 cells. IFI16 in GT1 cells was translocated into cytoplasm from nuclei, which was attributed to immune response to cytosolic dsDNA. TNF-α enhanced transfected dsDNA-induced CXCL10, and knockdown of IFI16 decreased TNF-α and dsDNA-driven CXCL10 expression in both RT7 and GT1 cells. Finally, the combination of TNF-α and transfected dsDNA resulted in translocation of IFI16 from nuclei to cytoplasm in RT7 cells. CONCLUSION RIG-I and IFI16 in oral mucosal cells may play important roles in host immune response against DNA viral infection, while TNF-α contributes to development of an antiviral system via those intracellular receptors.

Abstract
Abstract
Background
Cardiac sarcoidosis is a cause of epicarditis and sustained life-threatening ventricular arrhythmias. These arrhythmias occasionally arise from epicardial. Positron emission tomogramphy-comututed tomography (PET-CT) is useful for diagnosis with sarcoidosis. However, the usefulness for prediction of ventricular arrhythmias in patients with cardiac sarcoidosis is unknown.
Objective
We hypothesized that the evaluation of pericardial fat inflammation could identify high-risk sarcoidosis patients for ventricular arrhythmias.
Methods
We enrolled 20 consecutive patients with cardiac sarcoidosis performed PET-CT between August 2016 and December 2018. In each case, we measured the maximum standardized uptake value (SUVmax) of pericardial fat around the left atrium, both ventricules, atrioventricular groove, and left main coronary.
Results
Seven patients experienced ventricular tachycardia (VT) or ventricular fibrillation (VF). VT/VF patients had significantly more complete right bundle branch block (P=0.035), larger left atrial dimension (P=0.021), larger left ventricular end-diastolic dimension (P=0.005), lower ejection fraction (P=0.007), and higher E/e' (P=0.004). SUVmax of pericardial fat in the roof of left atrium (LA) and left ventricular (LV) with VT/VF patients were significantly higher than non-VT/VF patients (LA: 1.63 vs 1.32, P=0.0311; LV: 1.84 vs 1.26, P=0.045). The cut-off values of SUVmax derived from the ROC curve in the roof of LA and LV are 1.47 and 1.59 respectively. The Kaplan Meire estimator showed that high SUVmax patients in the roof of LA had significantly more detection of NSVT.
Conclusions
Our results suggest the relationship between SUVmax and VT/VF occurrence in patients with cardiac sarcoidosis. The evaluateon of SUVmax may be useful for VT/VF risk stratification.

Abstract
Abstract
Background
Using excised human left atrial appendage samples, we previously demonstrated that epicardial adipose tissue (EAT) are highly associated with atrial myocardial fibrosis as a substrate of atrial fibrillation (AF). We also reported the relationship between Angptl2 in EAT and atrial fibrosis. However, the mechanism is not clear. The purpose is to clarify the mechanisms underlying the effect of EAT on the atrial myocardium.
Methods
Human peri-left atrial EAT and abdominal subcutaneous adipose tissue (SAT) samples were obtained from 6 cases (2 females, 70.2±13.2 years). 50 mg of EAT and SAT were quickly washed with PBS and centrifuged 1min at 1200rpm. After 3 times this procedures, adipose tissues were cultured in DMEM F12 medium with Fetal bovine Serum (FBS) overnight.
After pre-incubation, EAT and SAT tissues were washed and centrifuge d three times and cultured in medium without FBS for 24hours. Finally, we collected oozed medium (conditioned medium) and used for experiments.
Concentrations of Angptl2 in conditioned medium were measured by ELISA.
To study the effects of conditioned medium, we used “organo-culture” system. Isolated atrium from 8week old male Sprague-Dawley rats were placed on the porous membrane with the endothelial face toward the membrane. After that, loading medium (conditioned medium:culture medium = 1:4), culture medium (control), or recombinant Angptl2 were dropped onto the epicardial face of the atrium once a day and incubated for 7 days (37°C, 5% CO2).
Then, histological and immunohistochemical analysis were performed. We also performed quantitative reverse transcription–polymerase chain reaction (RT–PCR) analysis.
Next, we isolated and cultured neonatal rat fibroblast and loaded Angptl2 for 24 hours.After collected these cells, we performed western blotting analysis.
Results
Atria organo-culture incubated for 7 days with conditioned medium showed global fibrosis. At epicardial side, fibrotic area of EAT group was significantly greater compared to that of SAT and control group (P<0.05).
mRNA of Col1a1, col3a1 and TGFβ1 were significantly increased in EAT group compared with the SAT and control group.
And, the concentration of conditioned medium created from EAT was significant higher than that from SAT (P<0.05).
Then, we dropped 500 ng/ml of recombinant Angptl2 onto the rat atria. Fibrotic area of Angptl22 group significantly greater than that of control with increasing number of α-SMA positive cells, and mRNA of col3a1 and TGFβ1 were significantly increased in Angptl2 group compared with control group.
In cultured fibroblasts, α-SMA and p-ERK expression were increased in Angptl2 group measured by western blotting analysis.
Conclusions
Our results demonstrated that EAT rather than SAT induces atrial myocardial fibrosis. There is a possibility that Angptl2 effused from EAT plays a part in atrial fibrosis thought EAT paracrine effect.

Abstract
Background: Several studies have shown that the neutrophil/lymphocyte ratio (NLR) is a marker that reflects the state of systemic inflammation. A high NLR was reported to be associated with cardiovascular events and mortality. However, little is known about the association between NLR and kidney disease progression in patients with chronic kidney disease (CKD). Therefore, the aim of the present study was to determine whether NLR is associated with renal outcomes in CKD patients. Methods: This prospective observational study included 350 consecutive patients with stage 1–4 CKD treated between June 2009 and November 2016. Data were collected until June 2017. The endpoint was the composite of end-stage renal disease requiring dialysis or death. Subjects were divided into two groups according to high and low NLR levels. A Cox proportional hazards model was used to determine the risk factors for composite outcomes. Results: The composite endpoint was observed in 83 patients during the median follow-up period of 31.8 months: 29 in the low NLR group and 54 in the high NLR group. Multivariable analysis showed that the high NLR group had a significant increase in the hazard ratio (HR) for composite outcomes (HR 1.67, 95% confidence interval 1.02–2.77) compared with the low NLR group. Conclusion: The present study demonstrated that a high NLR was associated with poor renal outcomes, suggesting that NLR may be a useful marker for prognostic prediction in patients with CKD.

Abstract
Background Blood urea nitrogen (BUN) is one of the substances that affects the calculated serum osmolality (cSosm). A previous study demonstrated that BUN and cSosm were independently associated with the development of chronic kidney disease (CKD) in patients with preserved kidney function. In advanced CKD stages, there is a concomitant increase in cSosm and BUN levels. However, it remains unclear whether BUN or cSosm levels are related to renal outcomes in patients with moderate to severe kidney dysfunction. The aim of this study was to clarify whether the BUN or cSosm level is associated with kidney disease progression in patients with advanced CKD. Methods In this prospective study, we enrolled 459 patients with CKD (stages 3–5). The composite renal endpoint was end-stage renal disease (ESRD) or death, and ESRD alone was added as an alternative outcome. A Cox proportional hazards model was utilized to determine the risk factors for a poor renal outcome. We adjusted for covariates including estimated glomerular filtration rate (eGFR). The cSosm (mOsm/kg) was calculated using the following formula: (2 × sodium) + (BUN/2.8) + (glucose/18). Results During a median follow-up of 25.8 months, the renal endpoint was observed in 210 patients. Multivariable Cox analysis determined the hazard ratio (HR) [95% confidence interval (CI)] for the composite renal outcome in the second, third, and fourth BUN quartiles were 1.36 (0.72–2.58), 1.87 (0.95–3.66), and 2.66 (1.23–5.76) (P for trend < 0.01), respectively compared with the first BUN quartile. Conversely, by multivariable Cox analysis, the HRs (95% CIs) for poor outcomes in the second, third, and fourth cSosm quartiles, compared with the first cSosm quartile, were 1.13 (0.69–1.87), 0.95 (0.58–1.55), and 1.26 (0.78–2.03), respectively (P for trend = 0.39). In addition, with regard to the renal outcome of ESRD alone, higher BUN quartiles had a significantly increased risk for the outcome, but cSosm levels were not associated with the outcome. Conclusions Higher BUN levels, but not cSosm levels, were associated with adverse renal outcomes independent of the eGFR, suggesting that BUN may be a useful marker for predicting kidney disease progression.

Abstract
Background In recent years, general surgery has faced a decline in applicants for postgraduate training. The St. George's Surgical Society hosted a national surgical conference with an aim to explore the reasons for the decline and to investigate the effectiveness of a one-day intervention on students' perceptions of general surgery and surgical skills. Materials and methods The conference took place on 20th January 2018 at St. George's, University of London. During the conference, medical students received lectures on "careers in surgery" and small-group workshops introducing students to simulation-based laparoscopic machines. Delegates were invited to complete before and after questionnaires looking at various domains; (1) Perceptions of general surgery, (2) Simulation skills, and (3) Usefulness of the day. Results There were significant impacts on student perceptions of the speciality such as increases in the views that "general surgery contained the opportunities for personal and professional development" (26%, p = 0.04), and of "general surgery as a rewarding speciality" (26%, p = 0.05). There were also negative changes such as an increase in the perception that "general surgery is female unfriendly" (+32%, p = 0.01). There were positive findings in all aspects relating to the use of laparoscopic simulation. Discussion The challenges faced in improving access to general surgery has been highlighted. More importantly the benefits of a one day intervention in addressing misconceptions and improving knowledge was seen. This study also shows the benefits of simulation teaching in the undergraduate curriculum. Conclusion The intervention has improved the perceptions on general surgery, surgical skills and knowledge and provided a platform for engaging students and clinicians.

Abstract
Aims/Introduction To explore the relationships between periodontitis and microvascular complications as well as glycemic control in type 2 diabetes patients. Materials and Methods This multicenter, hospital‐based, cross‐sectional study included 620 patients with type 2 diabetes. We compared the prevalence and severity of periodontitis between patients with ≥1 microvascular complication and those without microvascular complications. We also compared the prevalence and severity of periodontitis among patients with different degrees of glycemic control. Results After adjusting for confounding factors, multiple logistic regression analysis showed that the severity of periodontitis was significantly associated with the number of microvascular complications (odds ratio 1.3, 95% confidence interval 1.1–1.6), glycated hemoglobin ≥8.0% (64 mmol/mol; odds ratio 1.6; 95% confidence interval 1.1–2.3), and older age (≥50 years; odds ratio 1.7; 95% confidence interval 1.1–2.6). However, the prevalence of periodontitis was not significantly associated with the number of microvascular complications, but was associated with male sex, high glycated hemoglobin (≥8.0% [64 mmol/mol]), older age (≥40 years), longer duration of diabetes (≥15 years) and fewer teeth (≤25). Furthermore, propensity score matching for age, sex, diabetes duration and glycated hemoglobin showed that the incidence of severe periodontitis was significantly higher among patients with microvascular complications than among those without microvascular complications (P < 0.05). Conclusions The number of microvascular complications is a risk factor for more severe periodontitis in patients with type 2 diabetes, whereas poor glycemic control is a risk factor for increased prevalence and severity of periodontitis.

Abstract
BACKGROUND Differences in the predictive value of daytime systolic blood pressure (SBP) and night-time SBP by ambulatory blood pressure monitoring on renal outcomes have not been fully investigated in chronic kidney disease (CKD) patients. This study compared the prognostic value between daytime and night-time SBP on renal outcomes in CKD.Methods and Results:This prospective observational study included 421 patients. The composite renal endpoint was endstage renal disease (ESRD) or death. Cox models were used to determine associations of daytime and night-time SBP with renal outcomes. There were 150 renal events (ESRD, 130; death, 20). Multivariable Cox analyses demonstrated that hazard ratios (HRs) [95% confidence interval (CI)] for composite renal outcomes of every 10-mmHg increase in daytime and night-time SBP levels were 1.13 (1.02-1.26) (P=0.02) and 1.15 (1.05-1.27) (P<0.01), respectively. In addition, compared with the 1st daytime or night-time SBP quartile, HRs (95% CI) for outcomes in the 2nd, 3rd, and 4th quartiles were: daytime SBP, 1.25 (0.70-2.25), 1.09 (0.61-1.94), and 1.58 (0.88-2.85; P=0.13) (P for trend=0.16); night-time SBP, 1.09 (0.61-1.96), 1.31 (0.76-2.28), and 1.82 (1.00-3.30; P=0.049) (P for trend=0.03), respectively. CONCLUSIONS Night-time SBP appeared superior to daytime SBP for predicting renal outcomes in this population of patients.

Abstract
OBJECTIVE Ameloblastoma (AM) shows locally invasive behaviour. However, biological investigations regarding regulation of gene expression associated with AM pathological features are difficult to perform, because AM cells can be passaged for a few generations due to senescence. We report a newly established immortalized AM cell line, AMB cells, by transfection with human telomerase reverse transcriptase (hTERT). Furthermore, we examined whether TNF-α modulates bone resorption-related genes, IL-6 and MMP-9 in cooperation with TGF-β or IFN-γ. MATERIALS AND METHODS Following transfection of an hTERT expression vector into AM cells using a non-viral method, the effects of cytokines on the expressions of IL-6 and MMP-9 mRNA were examined using real-time PCR. TNF-α-induced NF-κB activity was examined by western blotting and transcription factor assays. RESULTS AMB cells continued to grow for more than 100 population doublings. Stimulation with TNF-α increased IL-6 and MMP-9 mRNA expressions, as well as NF-κB activation. Furthermore, TGF-β and IFN-γ dramatically increased TNF-α-mediated expressions of MMP-9 and IL-6 mRNA, respectively, while those responses were suppressed by NF-κB inhibitor. CONCLUSION We established an immortalized AM cell line by hTERT transfection. TNF-α-mediated regulation of MMP-9 and IL-6 via NF-κB may play an important role in the pathological behaviour of AMs, such as bone resorption.

Abstract
OBJECTIVE In patients with preserved kidney function, a positive association of fibroblast growth factor 23 (FGF23) with serum uric acid (SUA) has been reported; however, the relationship in overall chronic kidney disease (CKD) patients has not been investigated. No report has examined the relationship between FGF23 and uric acid clearance (CUA). The aim of the present study was to determine whether FGF23 is independently associated with urate metabolism in patients with CKD stages 1-5. MATERIALS AND METHODS In this cross-sectional study, 537 CKD patients were enrolled. SUA, CUA, FGF23, parathyroid hormone (PTH), and 1,25-dihydroxyvitamin D (1,25(OH)2D) were measured. Multivariable linear regression analysis was applied to determine independent factors associated with SUA or CUA. RESULTS In all patients, both SUA and CUA were independently associated with male sex, use of diuretics, use of uric acid-lowering agents, estimated glomerular filtration rate, and log FGF23 (β=0.29, P<0.01 for SUA; β=-0.11, P<0.01 for CUA), but not with log PTH or log 1,25(OH)2D. Dyslipidemia and diabetes were also independent factors for SUA and CUA, respectively. In multivariable analyses by sex, log FGF23 was associated with SUA in both sexes (β=0.32, P<0.01 in males vs. β=0.20, P=0.02 in females). Conversely, log FGF23 was independently associated with CUA in males (β=-0.15, P<0.01), but not in females (β=-0.09, P=0.17). CONCLUSIONS FGF23 was independently associated with urate metabolism in this population of CKD patients. FGF23 might also have a stronger association with urate metabolism in males compared with females.

Abstract
The records of 70 patients with oral cancer who were treated at a single institution between 2008 and 2014 were reviewed. The body temperature, white blood cell count, and C-reactive protein (CRP) levels were compared between those who had received preoperative oral care (oral care group) and those who had not received any (non-oral care group). When the patients were divided into those who underwent minimally invasive surgery and those who underwent severely invasive surgery, the mean CRP level in the early postoperative period was lower in the oral care group as compared with the non-oral care group in those who underwent minimally invasive surgery as well as those who underwent severely invasive surgery. However, the mean CRP level was most evidently reduced in the severely invasive group on days 1 and 3-5. However, no significant differences were observed with regard to the percentage of postoperative infectious complications (for example, surgical site infection, anastomotic leak and pneumonia) between the oral care (13.6%) and non-oral care (20.8%) groups, though a reduced prevalence of postoperative complications following preoperative oral care was noted. The results of the present study suggest that preoperative oral care can decrease inflammation during the early postoperative stage in patients with oral cancer who undergo severely invasive surgery.

Abstract
The report is the first of purification, overproduction, and characterization of a unique γ-butyrobetainyl CoA synthetase from soil-isolated Agrobacterium sp. 525a. The primary structure of the enzyme shares 70-95% identity with those of ATP-dependent microbial acyl-CoA synthetases of the Rhizobiaceae family. As distinctive characteristics of the enzyme of this study, ADP was released in the catalytic reaction process, whereas many acyl CoA synthetases are annotated as an AMP-forming enzyme. The apparent Km values for γ-butyrobetaine, CoA, and ATP were, respectively, 0.69, 0.02, and 0.24 mM.

Abstract
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8 deg2 of the Galactic bulge by the OGLE, MOA, and Wise microlensing surveys. During this period, 224 microlensing events were observed by all three groups. Over 12% of the events showed a deviation from single-lens microlensing, and for ~1/3 of those the anomaly is likely caused by a planetary companion. For each of the 224 events we have performed numerical ray-tracing simulations to calculate the detection efficiency of possible companions as a function of companion-to-host mass ratio and separation. Accounting for the detection efficiency, we find that 55 - 22 + 34 % of microlensed stars host a snowline planet. Moreover, we find that Neptunes-mass planets are ~ 10 times more common than Jupiter-mass planets. The companion-to-host mass ratio distribution shows a deficit at q ~ 10-2, separating the distribution into two companion populations, analogous to the stellar-companion and planet populations, seen in radial-velocity surveys around solar-like stars. Our survey, however, which probes mainly lower-mass stars, suggests a minimum in the distribution in the super-Jupiter mass range, and a relatively high occurrence of brown-dwarf companions.

Abstract
The aim of the present study was to examine whether interconnected porous hydroxyapatite ceramics (IP-CHA) could be used as bone substitute for implant treatment in reconstructive surgery. We firstly assessed if surround of the titanium surface placed into granular or block-type IP-CHA can observe new bone formation in a rabbit bone defect model. Subsequently, osseointegration and stability of titanium implant inserted into block-type IP-CHA was investigated in a rabbit onlay graft model. Direct contact between new bone and the surface of the titanium in granular- or block-type IP-CHA was found in a rabbit bone defect. Further, new bone formation was found in direct contact with the implant surface in the block-type IP-CHA in an onlay graft model, and the implant stability quotient (ISQ) values were significantly increased after surgery. Therefore, IP-CHA may be a useful material for implant treatment in reconstructive surgery strategies.

Abstract
OBJECTIVE Serum bilirubin has been reported to be associated with the progression of kidney disease in patients with diabetic nephropathy. Less is known, however, about the relationship between bilirubin and chronic kidney disease (CKD) of other etiologies. This study was designed to clarify whether serum total bilirubin concentration is associated with kidney disease progression in patients with CKD independent of etiology. MATERIALS AND METHODS This prospective observational study enrolled 279 consecutive patients with stages 3-5 CKD. The renal endpoint was the composite of the doubling of serum creatinine or end-stage renal disease requiring dialysis. Patients were divided into three groups by their serum total bilirubin concentrations: ≤0.3 (lowest), 0.4-0.5 (middle), and ≥0.6 (highest) mg/dL. A Cox proportional hazards model was applied to determine the risk factors for poor renal outcome. RESULTS The median follow-up period was 21months. One-hundred and three patients reached renal end points. After multivariable adjustment, a 0.1mg/dL increase in serum bilirubin was associated negatively with poor renal outcome (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.60-0.87). In addition, after adjustment for confounding factors, including traditional and nontraditional cardiovascular risk factors, the middle (HR 3.14, 95% CI 1.36-8.57) and lowest (HR 4.22, 95% CI 1.81-11.59) bilirubin groups had significantly higher HRs for renal outcome than the highest bilirubin group. CONCLUSIONS Lower serum bilirubin concentration was independently associated with adverse renal outcomes, suggesting that the measurement of serum bilirubin is useful for predicting kidney disease progression in patients with moderate to severe CKD.

Abstract
We report a case of advanced gastric cancer that was successfully treated with second-line chemotherapy followed by curative conversion gastrectomy. The patient was a 71-year-old man. Endoscopic examination revealed a type 3 gastric cancer in the lower third of the stomach. Abdominal computed tomography (CT) revealed multiple lymph node metastases and metastasis to the peritoneal cavity. The clinical diagnosis was cT4N3aP1H0M1(LYM), cStage IV. The patient was treated with S-1 (80 mg/m² on days 1-28, every 6 weeks [q6w]) in November 2009. Temporarily, both the size of the primary lesion and the swelling of the lymph nodes were markedly reduced. However, after 10 courses of chemotherapy, the primary lesion was found to be enlarged again. The patient was then treated with S-1(80 mg/m², on days 1-14, every 6 weeks [q3w]) plus CPT- 11 (150 mg/m² on day 1, q3w) as the second-line chemotherapy. After 8 courses, an abdominal CT showed no peritoneal or lymph node metastases, but gastric endoscopy revealed the presence of a residual primary lesion. After staging laparoscopy, distal gastrectomy with D2 lymphadenectomy was performed. The histological diagnosis was ypT3 (SS) N1M0, Stage IIB. Analysis of the histological features of the primary tumor and peritoneal metastases resulted in their classifications as Grade 1a and Grade 3, respectively. After surgery, there were no serious adverse events. The patient has been in good health without recurrence for over 3 years after surgery.

Abstract
We report a patient with metachronous triple cancer of the hypopharynx, esophagus, and tongue. A 37-year-old man with hypopharyngeal cancer underwent hypopharyngolaryngectomy and cervical lymphadenectomy in 1999. Submental lymphadenectomy following adjuvant radiotherapy was performed for lymph node recurrence in 2000. The patient then underwent esophagectomy for esophageal cancer in 2004. Subsequently, the patient underwent 2 partial resections and 1 subtotal resection of the tongue for tongue cancer in 2005, 2007, and 2008, respectively. The pathological findings for each cancer were squamous cell carcinoma. Two rounds of radiotherapy were performed for bone metastasis of the esophageal cancer and for the local recurrence of the tongue cancer. A total of 7 lines of chemotherapy, including superselective arterial infusion chemotherapy, were administered to treat the recurrences. The patient died in 2013, but he showed long-term survival of 13 years from the first operation owing to the multimodality treatment.

Abstract
PURPOSE The efficacy of chemotherapy for advanced or recurrent gastric cancer in patients who were aged over 75 years was investigated. MATERIALS AND METHODS Progression free survival (PFS) and overall survival (OS) of advanced gastric cancer patients who received first-line chemotherapy with TS-1 plus cisplatin or TS-1 in our hospital from 2009 to 2013 were determined. The patients were divided into two groups: H and L. H group patients were aged over 75 years, and L group patients were aged less than 75 years. RESULTS Median PFS and median OS of patients in the H and L groups who received TS-1 plus cisplatin chemotherapy were not significantly different. PFS was 77[range, 13-211] days and 139[range, 53-211]days for the H and L groups, respectively(p=0.141), while OS was 523[range, 22-1,030] days and 402 [range, 322-623] days, respectively (p=0.620). Similarly, median PFS and median OS of patients who received TS-1 chemotherapy were not significantly different between the H and L groups. PFS was 103[range, 51-156]days and 152.5[range, 85-278]days for the H and L groups, respectively (p=0.230), while OS was 414 [range, 224-714]days and 605[range, 452-1,077] days, respectively ( p=0.1337). CONCLUSION PFS and OS were not significantly different in younger patients with advanced gastric cancer who received TS-1 plus cisplatin or TS-1 chemotherapy compared to that in similarly treated elderly patients with advanced gastric cancer.

Abstract
BACKGROUND Innate immune response by oral mucosal cells may be the first line of host defense against viral infection. Retinoic acid-inducible gene-I (RIG-I) recognizes viral dsRNA in the cytoplasm, and RIG-I-mediated signaling regulates antiviral type I IFN, and inflammatory chemokine production. Here, we tested the hypothesis that oral mucosal cell participation in host defense against viral infection via RIG-I. METHODS RIG-I expression was detected in immortalized oral keratinocytes (RT7), oral fibroblasts (GT1) using and RT-PCR and immunohistochemistry. RT7 and GT1 were exposed to dsRNA virus mimic Poly I:C-LMW/LyoVec (PLV). Expression of IFN-β and CXCL10 via RIG-I was examined by Real-time RT-PCR and ELISA. Phosphorylation of IRF3 and STAT1 were detected by western blotting. RESULTS RT7 and GT1 constitutively expressed RIG-I in the cytoplasm. Furthermore, PLV increased IFN-β and CXCL10 productions in both RT7 and GT1 via RIG-I concurrent with phosphorylation of IRF3 and STAT1. PLV-induced CXCL10 production was attenuated by neutralization of IFN-β and blocking of IFN-α/β receptor (IFNAR), indicating primal IFN-β production via the RIG-I-IRF3 axis, which eventually induces CXCL10 production via the IFNAR -STAT1 axis. CONCLUSION We propose that RIG-I in oral keratinocytes and fibroblasts may cumulatively develop host-defense mechanisms against viral infection in oral mucosa.

Abstract
Toll-like receptor (TLR) family members are pattern recognition receptors that are essential in the activation of innate and adaptive immune responses. Submandibular gland epithelial cells (SMGCs) may recognize microbial components through TLRs and be involved in the development of inflammatory reactions in the submandibular glands. Therefore, the functional expression of TLRs in SMGCs was investigated in the present study. The mRNA expression of TLRs in SMGC and whole submandibular tissues was determined by RT-PCR. Subsequently, the effects of various TLR agonists and tumor necrosis factor alpha (TNF-α) on IL-8 production were examined using an ELISA. SMGCs, as well as whole submandibular tissues, expressed TLR1-10 mRNA. Furthermore, interleukin (IL)-8 production in SMGCs was increased by Pam3CSK4 (TLR1/2 agonist), poly I:C (TLR3 agonist), E. coli lipopolysaccharide (LPS; TLR4 agonist), flagellin (TLR5 agonist) and macrophage‑activating lipopeptide (MALP)-2 (TLR2/6 agonist) treatments in a dose‑dependent manner, whereas administration of either imiquimod (TLR7 agonist) or CpG-oligodeoxynucletide (TLR9 agonist) exerted no evident effect. Pam3CSK4, poly I:C, LPS, flagellin and MALP-2 also enhanced TNF‑α‑induced IL-8 production in SMGCs. These findings suggest that innate immune responses against microbial components result in the development of TNF-α-mediated autoimmune inflammatory disease in the submandibular glands.

Abstract
The ankle-brachial blood pressure index (ABPI) has been recognized to have a predictive value for cardiovascular (CV) events and mortality in general or dialysis populations. However, the associations between ABPI and those outcomes have not been fully investigated in predialysis patients. The present study aimed to clarify the relationships between ABPI and both CV events and mortality in Japanese chronic kidney disease (CKD) patients not on dialysis. In this prospective observational study, we enrolled 320 patients with CKD stages 3-5 who were not on dialysis. At baseline, ABPI was examined and a low ABPI was defined as <0.9. CV events and all-cause deaths were examined in each patient. A Cox proportional hazards model was applied to determine the risk factors for CV events, as well as for mortality from CV and all causes. The median follow-up period was 30 months. CV events occurred in 56 patients and all-cause deaths occurred in 48, including 20 CV deaths. Multivariate analysis showed that age and low ABPI were risk factors for CV events. It was demonstrated that age, a history of cerebrovascular disease and low ABPI were determined as independent risk factors for CV mortality. In addition, age, body mass index and low ABPI were independently associated with all-cause mortality. In patients with CKD, low ABPI during the predialysis period is independently associated with poor survival and CV events, suggesting the usefulness of measuring ABPI for predicting CV events and patient survival in CKD.
