Skeletal muscle mass and function are affected by pancreatic atrophy, pancreatic exocrine insufficiency and poor nutritional status in patients with chronic pancreatitis.

BACKGROUND/OBJECTIVE: Previous studies have demonstrated that sarcopenia is frequently observed in patients with chronic pancreatitis (CP). However, most studies have defined sarcopenia solely based on skeletal muscle (SM) loss, and muscle weakness such as grip strength (GS) reduction has not been considered. We aimed to clarify whether SM loss and reduced GS have different associations with clinical characteristics and pancreatic imaging findings in patients with CP. METHODS: One hundred two patients with CP were enrolled. We defined SM loss by the SM index at the third lumbar vertebra on CT (<42 cm2/m2 for males and <38 cm2/m2 for females), and reduced GS by < 28 kg for males and <18 kg for females. RESULTS: Fifty-seven (55.9 %) patients had SM loss, 21 (20.6 %) had reduced GS, and 17 (16.7 %) had both. Patients with SM loss had lower body mass index, weaker GS, higher Controlling Nutritional Status score, lower serum lipase level, and lower urinary para-aminobenzoic acid excretion rate, suggesting worse nutritional status and pancreatic exocrine insufficiency. On CT, main pancreatic duct dilatation and parenchymal atrophy were more frequent in patients with SM loss than in those without it. Patients with reduced GS were older and had worse nutritional status than those without it. CONCLUSIONS: SM loss was associated with pancreatic exocrine insufficiency, low nutritional status, and pancreatic imaging findings such as parenchymal atrophy and main pancreatic duct dilatation, whereas older age and low nutritional status led to additional reduced GS.

A Novel Dry Simulator Model for Learning Comprehensive Endoscopic Retrograde Cholangiopancreatography/Endoscopic Sphincterotomy Procedures while Minimizing Adverse Bleeding Events (with Video).

INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST) are essential skills for performing endoscopic cholangiopancreatic procedures. However, these procedures have a high incidence of adverse events, and current training predominantly relies on patient-based approaches. Herein, we aimed to develop an ERCP/EST simulator model to address the need for safer training alternatives, especially for learners with limited ERCP experience. METHODS: The model was designed to facilitate the use of actual endoscopic devices, supporting learning objectives that align with the components of the validated Bethesda ERCP Skill Assessment Tool (BESAT). BESAT focuses on skills, such as papillary alignment, maintenance of duodenoscope position, gentle and efficient cannulation, controlled sphincterotomy in the correct trajectory, and guidewire manipulation. Thirty gastroenterology trainees used the simulator between May 2022 and March 2023, and their satisfaction was assessed using a visual analog scale (VAS) and pre- and post-training questionnaires. RESULTS: The novel simulator model comprised a disposable duodenal papillary section, suitable for incision with an electrosurgical knife, alongside washable upper gastrointestinal tract and bile duct sections for repeated use. The duodenal papillary section enabled reproduction of a realistic endoscope position and the adverse bleeding events due to improper incisions. The bile duct section allowed for the reproduction of fluoroscopic-like images, enabling learners to practice guidewire guidance and insertion of other devices. Following training, the median VAS score reflecting the expectation for model learning significantly increased from 69.5 (interquartile range [IQR]: 55.5-76.5) to 85.5 (IQR: 78.0-92.0) (p < 0.01). All participants expressed a desire for repeated simulator training sessions. CONCLUSIONS: This innovative simulator could serve as a practical educational tool, particularly beneficial for novices in ERCP. It could facilitate hands-on practice with actual devices, enhancing procedural fluency and understanding of precise incisions to minimize the risk of bleeding complications during EST.

Association between pre-treatment with statin and its inhibitory effect on the onset of coronary artery disease at the time of coronary computed tomography angiography: a new look at an old medication.

Coronary artery stenosis is often advanced by the time coronary computed tomography angiography (CCTA). Statins are the most important anti-lipidemic medication for improving the prognosis of coronary artery disease (CAD) patients. Although lipid-lowering therapy using statins appears to have been established as a method for preventing CAD, there remains the problem that CAD cannot be completely suppressed. In this study, we investigated whether pre-treatment with statin could significantly inhibit the onset of CAD when patients received CCTA for screening of CAD. The subjects were 1164 patients who underwent CCTA as screening for CAD. CAD was diagnosed when 50% or more coronary stenosis was present in the coronary arteries. Patient backgrounds were investigated by age, gender, body mass index, coronary risk factors [family history of cardiovascular diseases, smoking history, hypertension (HTN), diabetes mellitus (DM), dyslipidemia, chronic kidney disease (CKD) or metabolic sydrome] and medications. Patients were classified into two groups according to the presence or absence of statin pre-administration during CCTA [statin (-) group (n = 804) and (+) group (n = 360)]. Compared with the statin (-) group, the statin (+) group was significantly older and had higher rates of family history, HTN, and DM. The statin (+) group had a significantly higher % CAD than the statin (-) group. Serum levels of low-density lipoprotein cholesterol (LDL-C) were significantly lower in the statin (+) group than in the statin (-) group. There was no significant difference in either high-density lipoprotein cholesterol levels or triglyceride levels between the two groups. Age, male gender, HTN, DM and pre-treatment with statin were all associated with CAD (+) in all patients. In addition, factors that contributed to CAD (+) in the statin (-) group were age, male gender, and DM, and factors that contributed to CAD (+) in the statin (+) group were age, smoking, HTN and % maximum dose of statin. At the time of CCTA, the statin (+) group had a high rate of CAD and coronary artery stenosis progressed despite a reduction of LDL-C levels. To prevent the onset of CAD, in addition to strict control of other coronary risk factors (HTN etc.), further LDL cholesterol-lowering therapy may be necessary.

GATA6 and CK5 Stratify the Survival of Patients With Pancreatic Cancer Undergoing Neoadjuvant Chemotherapy.

Relevant protein expression of GATA6, CK5, vimentin, and mucins using immunohistochemistry was assessed for predicting the prognosis of and chemotherapy efficacy in patients with pancreatic cancers (PCs). The protein expression was examined in 159 PCs resected after neoadjuvant chemotherapy (NAC-PCs) and compared with that of 120 matched biopsy specimens taken before NAC. KRAS mutations were assessed by digital PCR. NAC-PCs were classified by GATA6 expression initially and CK5 expression subsequently into 4 types: classical-type (n = 22) with GATA6-high (≥50%)/CK5-low (<10%) PCs; hybrid-type (n = 45) with GATA6-high/CK5-high (≥10%) PCs; basal-like-type (n = 53) with GATA6-low (<50%)/CK5-high (≥30%) PCs; and null-type (n = 39) with GATA6-low/CK5-low (<30%) PCs, which resulted in clear stratification of patient prognosis. The classical-type was associated with the most favorable prognosis, whereas the null-type was associated with the worst prognosis (multivariate hazard ratio: 3.56; 95% CI, 1.63-7.77; P = .0015). The hybrid and basal-like types correlated with in-between levels of prognosis. The risk of hepatic recurrence was lower in the classical-type than in null (multivariate odds ratio [mOR]: 0.18; 95% CI, 0.04-0.96; P = .0449) and basal-like (mOR: 0.24; 95% CI, 0.05-1.16; P =.0750) types. By contrast, the risk of locoregional recurrence was higher in the classical-type than in the basal-like-type (mOR: 5.03; 95% CI, 1.20-21.1; P = .0272). The hybrid-type was subclassified into transition and coexpression patterns with different gastric mucin expression levels. High levels of vimentin (≥10%, n = 30) in pre-NAC-PC tissues was associated with poor prognosis (P = .0256). Phenotypic transitions between pre-NAC and post-NAC-PCs were common (73/120; 61%). PCs with NAC regression grades 2 and 3 showed a transition to poorer prognostic phenotypes (P = .0497). KRAS mutations were not associated with these phenotypes. In conclusion, GATA6 and CK5 immunohistochemical expression phenotypes may stratify the survival of patients with NAC-PCs and reflect post-NAC phenotypic transitions associated with poor prognosis. Prompt evaluation of immunohistochemical phenotypes may contribute to designing a precision therapeutic strategy for patients with PCs.

The M-ANNHEIM-AiP-Activity-Score is useful for predicting relapse in patients with type 1 autoimmune pancreatitis.

BACKGROUND/OBJECTIVES: Proper assessment of disease activity and prediction of relapse are crucial for the management of autoimmune pancreatitis (AIP). The M-ANNHEIM-AiP-Activity-Score (MAAS) has been proposed to determine disease activity and predict relapse in German and Swedish patients with AIP. MAAS is calculated using six categories: pain report, pain control, exocrine insufficiency, endocrine insufficiency, imaging, and complications. This study aimed to clarify the usefulness of MAAS to predict relapse in Japanese patients with type 1 AIP. METHODS: We retrospectively analyzed 117 patients with type 1 AIP undergoing initial and maintenance steroid treatments at our institute between April 2006 and March 2021. AIP was diagnosed according to the Japanese Diagnostic Criteria for AIP 2018. We examined the association of MAAS with relapse during and after maintenance treatment. RESULTS: MAAS (median, 8 points) at the start of the initial treatment was reduced after treatment (median, 4 points; P < 0.001). A MAAS ≥11 points at the start of the initial treatment was associated with relapse. The initial treatment-induced reduction of MAAS<60% was more frequent in patients with relapse (75.0%) than in patients without relapse (37.6%; P = 0.007). MAAS at the start of maintenance treatment was higher for patients with relapse (median, 5 points) than that for patients without relapse (median, 4 points; P = 0.007). MAAS ≥4 points at the start of maintenance treatment was associated with subsequent relapse. CONCLUSIONS: MAAS is useful for predicting relapse in patients with type 1 AIP undergoing maintenance therapy.

Clinical Outcomes of Inside Stents and Conventional Plastic Stents as Bridge-to-Surgery Options for Malignant Hilar Biliary Obstruction.

BACKGROUND: The appropriate method of preoperative endoscopic biliary drainage (EBD) for cholangiocarcinoma with hilar biliary obstruction remains controversial. The inside-stent technique is a method of placing plastic stents entirely inside the bile duct. Several studies of patients with unresectable stage have reported longer stent patency compared with conventional endoscopic biliary stenting (EBS). Inside-stent techniques have been introduced as a bridge-to-surgery option and as an alternative to conventional EBS. AIMS: We aimed to evaluate the clinical outcomes of inside stent use and conventional EBS. METHODS: During this retrospective multicenter study, we reviewed consecutive patients with cholangiocarcinoma who underwent radical surgery after conventional EBS or inside-stent insertion. Adverse event (AE) rates after EBD and post-surgical AEs were compared. A multivariable analysis was performed to identify factors affecting cholangitis after EBD. RESULTS: Conventional EBS and inside-stent procedures were performed for 56 and 73 patients, respectively. Patient backgrounds were similar between groups, except for percutaneous transhepatic portal vein embolization. The waiting time before surgery was similar between groups (28.5 days vs. 30 days). There were no significant differences in the cholangitis rate (21.4% vs. 26.0%; P = 0.68) and all AEs (25.0% vs. 30.1%; P = 0.56) between groups. The post-surgical AE rate was similar between the groups. The multivariable analysis found that preprocedural cholangitis was a risk factor for cholangitis after EBD (odds ratio: 5.67; 95% confidence interval: 1.61-19.9). CONCLUSIONS: The outcomes of inside-stent techniques and conventional EBS for the management of preoperative EBD are comparable for patients with cholangiocarcinoma.

Association between paroxysmal or persistent atrial fibrillation and hyperuricemia in patients who underwent coronary computed tomography angiography: from the FU-CCTA-AF Registry.

BACKGROUND: Hyperuricemia (HU) and hypertension (HTN) contribute to atherosclerotic cardiovascular disease, and both are also involved in the onset and development of atrial fibrillation (AF). OBJECTIVE: In the present study, we investigated the association between risk factors for atherosclerosis [including HU, HTN, blood pressure and serum uric acid (UA) levels] and paroxysmal atrial fibrillation (Paro-AF) or persistent atrial fibrillation (Pers-AF) in patients who underwent coronary computed tomography angiography (CCTA). METHODS: We enrolled 263 patients from the Fukuoka University-CCTA-AF (FU-CCTA-AF Registry) who underwent CCTA prior to AF ablation therapy. AF was classified as either Paro-AF (≤ 7 days) or Pers-AF (> 7 days). HU was diagnosed by a serum UA level > 7.0 mg/dl, and coronary artery disease (CAD) was diagnosed when CCTA results showed ≥ 50% significant coronary artery stenosis. The number of significantly diseased coronary artery vessels (VD), the Gensini score and the coronary artery calcification score (CACS) were measured. Left atrial morphology was also evaluated. RESULTS: Diastolic blood pressure and HbA1c in the Pers-AF group were significantly higher than those in the Paro-AF group. The Pers-AF group showed a significantly higher prevalence of HU and higher UA levels than the Paro-AF group. In a multivariate logistic regression analysis, HU was an independent associated factor to Pers-AF (odds ratio: 2.023, 95% confidence interval: 1.055-3.881, p = 0.034), while HTN was not. CONCLUSION: In patients with AF, HU is associated with Pers-AF.

Association between major adverse cardiovascular events and pentraxin-3 in patients who have undergone coronary computed tomography angiography: from the FU-CCTA registry.

Chronic vasculitis is considered to be associated with future cardiovascular events. Here, we present major cardiovascular events (MACEs) in patients who underwent coronary computed tomography angiography (CCTA) for screening for coronary artery disease (CAD), and the association between MACEs and the inflammation marker pentraxin (PTX)-3 or highly sensitive C-reactive protein (hsCRP). The patients who underwent CCTA for the purpose of screening for CAD at Fukuoka University Hospital (FU-CCTA registry), 456 patients with suspected CAD or at least one cardiovascular risk factor were followed for up to 5 years. The levels of PTX-3 and hsCRP in blood were measured at the time of CCTA, and the patients were divided into two groups according to the presence (MACEs group) or absence (non-MACEs group) of MACEs. There were no differences in PTX-3 or hsCRP between the MACEs (-) and MACEs ( +) groups in all patients. A multivariate analysis related to the presence or absence of MACEs by logistic regression analysis of inflammation factors (PTX-3 and hsCRP) in addition to conventional risk factors as independent variables was performed. PTX-3 was a predictor of MACEs in males, whereas smoking, but not PTX-3, was a predictor of MACEs in females. PTX-3 could be a predictor of MACEs in males, but not females.

Endoscopic nasobiliary drainage versus endoscopic biliary stenting for preoperative biliary drainage in patients with malignant hilar biliary obstruction: Propensity score-matched multicenter comparative study.

OBJECTIVES: For preoperative biliary drainage (PBD) of malignant hilar biliary obstruction (MHBO), current guidelines recommend endoscopic nasobiliary drainage (ENBD) due to the higher risk of cholangitis after endoscopic biliary stenting (EBS) during the waiting period before surgery. However, few studies have supported this finding. Therefore, we aimed to compare the outcomes of preoperative ENBD and EBS in patients with MHBO. METHODS: Patients with MHBO who underwent laparotomy for radical surgery after ENBD or EBS were included from retrospectively collected data from 13 centers (January 2014 to December 2018). We performed a 1:1 propensity score matching between the ENBD and EBS groups. These patients were compared for the following: cholangitis and all adverse events (AEs) after endoscopic biliary drainage (EBD) until surgery, time to cholangitis development after EBD, postsurgical AEs, and in-hospital death after surgery. RESULTS: Of the 414 patients identified, 355 were analyzed in this study (226 for ENBD and 129 for EBS). The matched cohort included 63 patients from each group. The proportion of cholangitis after EBD was similar between the two groups (20.6% vs. 25.4%, P = 0.67), and no significant difference was observed in the time to cholangitis development. The proportions of surgical site infections, bile leaks, and in-hospital mortality rates were similar between the groups. CONCLUSION: For PBD of MHBO, the proportion of AEs, including cholangitis, after EBD until surgery was similar when either ENBD or EBS was used.

Salivary Polyamines Help Detect High-Risk Patients with Pancreatic Cancer: A Prospective Validation Study.

Pancreatic cancer is one of the most malignant cancer types and has a poor prognosis. It is often diagnosed at an advanced stage because of the absence of typical symptoms. Therefore, it is necessary to establish a screening method for the early detection of pancreatic cancer in high-risk individuals. This is a prospective validation study conducted in a cohort of 1033 Japanese individuals (male, n = 467, age = 63.3 ± 11.5 years; female, n = 566, age = 64.2 ± 10.6 years) to evaluate the use of salivary polyamines for screening pancreatic diseases and cancers. Patients with pancreatic cancer were not included; however, other pancreatic diseases were treated as positive cases for accuracy verification. Of the 135 individuals with elevated salivary polyamine markers, 66 had pancreatic diseases, such as chronic pancreatitis and pancreatic cysts, and 1 had gallbladder cancer. These results suggest that the salivary polyamine panel is a useful noninvasive pancreatic disease screening tool.

Effects of a 14-week community health program of exercise and learning/education in older adults: A single-arm pre-post comparison study.

This study was initiated in 2022 in Miyaki Town, Saga Prefecture, Japan, to determine the impact of an intervention that combined brain and physical function training and health education in older residents. Miyaki has a population of approximately 26,000, 35% of whom are considered to be aging. A 14-week program consisting of strength training, brain function training, and health lectures was conducted with 34 older residents of the community. Body composition, motor function, brain function, and various blood tests were evaluated before and after the intervention. Brain function was assessed using the Trail Making Test-A. Physical function was assessed by Open-Close Stepping, Functional Reach Test, Open-Leg Standing Time, and Two-Step Test. The intervention group showed significant improvements in brain function (p< 0.0001), physical function (p = 0.0037), body composition (p = 0.0053), and LDL-C (p = 0.017). This study provides substantial evidence that community-based combined programs can be beneficial for older adults.

The Effectiveness of Mobile Cloud 12-Lead Electrocardiogram Transmission System in Patients with ST-Segment Elevation Myocardial Infarction.

Backgroundand Objectives: Delay of reperfusion therapy is related to high mortality in cases of ST-segment elevation myocardial infarction (STEMI). Guidelines emphasize that the first-medical-contact-to-balloon (FMCTB) time should be within 90 min. A mobile cloud-based 12-lead electrocardiogram (MC-ECG) transmission system might be useful in such cases, especially in rural areas. Materials and Methods: From April 2019 to June 2021, both an MC-ECG transmission system and the conventional method in which a physician checks the ECG in a hospital (Conventional) were used for transport by emergency medical services in Shin-Yukuhashi Hospital, Fukuoka, Japan. During this period, 8684 consecutive patients were transported to this hospital. Among them, we investigated 48 STEMI patients. The MC-ECG group (n = 23) and the Conventional group (n = 25) were enrolled. Results: There was no significant difference in FMCTB time between the MC-ECG and Conventional groups (MC-ECG: 72.0 (60.5-107) min vs. Conventional: 80.0 (63.0-92.0) min, p = 0.77). The length of hospital stay in the MC-ECG group was significantly shorter than that in the Conventional group (12.0 (10.0-15.0) days vs. 16.0 (12.0-19.0) days, p = 0.039). The logistic regression model showed that patients' non-use of MC-ECG was associated with a risk of more than 15-day length of hospital stay with an adjusted odd ratio of 0.08 (95% CI: 0.013-0.55, p = 0.0098). Conclusions: Using the MC-ECG, the length of hospital stay in patients with STEMI was significantly reduced.

Differences in lesion characteristics and patient background associated with the medium-term clinical outcomes of bare-metal and first-, second- and third-generation drug-eluting stents.

We investigated the lesion characteristics and patient background factors associated with the medium-term incidence of major adverse cardiac events (MACEs) for bare-metal stents (BMS) and 1st-, 2nd- and 3rd-generation drug-eluting stents (DES) using the PCI-Registry (FU-Registry). Between January 2003 and March 2016, 2967 cases/3508 lesions for which percutaneous coronary intervention was performed at Fukuoka University Hospital and related facilities were enrolled. Patients were divided into BMS and 1st-, 2nd- and 3rd-generation drug-eluting stent (DES) groups. The incidence of MACEs in the BMS group (26.2%) was significantly higher than those in the 1st, 2nd and 3rd DES groups (18.0%, 12.5%, and 11.0%, respectively). The incidence of MACEs in the BMS group was strongly associated with insulin use, hemodialysis, low high-density lipoprotein cholesterol, stent minimum lesion diameter, stent length, severe calcification and a small vessel diameter of less than 2.5 mm. Some of these factors showed no association with MACEs among the drug-elution groups, and only hemodialysis, arteriosclerosis obliterans and severe calcification showed a strong correlation in the 2nd DES group. In the 3rd DES group, none of the factors considered were associated with MACEs. In conclusion, in stent implantation, the number of factors associated with MACEs has gradually decreased as the stent generation increased.

Associations between smoking habits and major adverse cardiovascular events in patients who underwent coronary computed tomography angiography as screening for coronary artery disease.

We analyzed whether smoking was associated with major adverse cardiovascular events (MACE) and the progression of coronary atherosclerosis as assessed by coronary computed tomography angiography (CCTA) as screening for coronary artery disease (CAD). We enrolled 443 patients who had all undergone CCTA and either were clinically suspected of having CAD or had at least one cardiovascular risk factor. We divided the patients into smoking (past and current smoker) and non-smoking groups and into males and females, and evaluated the presence of CAD, severity of coronary atherosclerosis and MACE (cardiovascular death, ischemic stroke, acute myocardial infarction and coronary revascularization) with a follow-up of up to 5 years. %CAD and the severity of coronary atherosclerosis in the smoking group were significantly higher than those in the non-smoking group. %MACE in males and smokers were significantly higher than those in females and non-smokers, respectively. Interestingly, Kaplan-Meier curves also showed that female non-smokers enjoyed significantly greater freedom from MACE than female smokers (p = 0.007), whereas there was no significant difference in freedom from MACE between male non-smokers and male smokers (p = 0.984). Although there were no significant predictors of MACE in all patients according to a multiple logistic regression analysis, smoking was useful for predicting MACE in females, but not males. In conclusion, smoking was significantly associated with MACE in females, but not males, who underwent CCTA as screening for CAD.

Association between high-density lipoprotein cholesterol levels and major adverse cardiovascular events in patients who underwent coronary computed tomography angiography: FU-CCTA registry.

It is unclear whether higher levels of serum high-density lipoprotein cholesterol (HDL-C) prevent major adverse cardiovascular events (MACE). We prospectively evaluated 501 patients who had undergone coronary computed tomography angiography at Fukuoka University Hospital and either were clinically suspected of having coronary artery disease (CAD) or had at least one cardiovascular risk factor with a follow-up of up to 5 years. The primary endpoint was MACE (cardiovascular death, ischemic stroke, acute myocardial infarction and coronary revascularization). The patients were divided into tertiles according to the HDL-C level: 47 mg/dl ≥ HDL-C level [n = 167, lower HDL-C level (L-HDL)], 58 mg/dl ≥ HDL-C level ≥ 48 mg/dl [n = 167, middle HDL-C level (M-HDL)] and HDL-C level ≥ 59 mg/dl [n = 167, higher HDL-C level (H-HDL)] groups. There were significant differences in %CAD among the L-HDL, M-HDL and H-HDL groups. Unexpectedly, there was no difference in %MACE between M-HDL and H-HDL, although %MACE in M-HDL was significantly lower than that in L-HDL (p < 0.05). By a multivariate logistic regression analysis, MACE in H-HDL-C was independently associated with diabetes mellitus (DM) (p = 0.03). A Kaplan-Meier curve according to the HDL subgroup indicated that M-HDL, not H-HDL, enjoyed the greatest freedom from MACE among the 3 groups (log-rank test p = 0.047). Finally, the results of a Cox regression model indicated that L-HDL and H-HDL had significantly higher risk of MACE than M-HDL. In conclusions, patients with middle HDL-C levels, not higher HDL-C levels, showed the greatest freedom from MACE. Patients with higher HDL-C levels need to be strictly managed for DM to prevent MACE.

Association between lipid profile and endothelial dysfunction as assessed by the reactive hyperemia index.

INTRODUCTION: We investigated the associations between endothelial dysfunction (ED) as evaluated by the reactive hyperemia index (RHI) obtained using Endo-PAT2000® and atherosclerotic risk factors in patients who underwent coronary artery angiography (CAG). METHODS: The subjects consisted of 191 patients who were clinically suspected to have CAD and underwent CAG, and in whom we could perform Endo-PAT2000®. We divided the patients into ED (RHI<1.67, n = 71) and non-ED (RHI≥1.67, n = 120) groups. RESULTS: The ED group was significantly older and showed a higher ratio of low-density lipoprotein cholesterol (LDL-C) to high-density lipoprotein cholesterol (HDL-C) (L/H) than the non-ED group. A multivariate logistic regression analysis was performed to examine the associations between the presence of ED and age, gender, and BMI in addition to L/H. Age [odds ratio (OR) = 1.03, p = .02] and L/H (OR = 1.64, p = .01) were identified as significant independent markers of the presence of ED. Next, we divided 122 patients with statin treatment into ED (n = 40) and non-ED (n = 82) groups. The ED group tended to have higher L/H and lower HDL-C than the non-ED group. HDL-C (OR = 0.95, p = .01) and age (OR = 1.05, p = .04) were identified as independent markers of the presence of ED. CONCLUSIONS: L/H was an independent marker of the presence of ED in patients without dyslipidemia. In addition, among patients with statin treatment, HDL-C was an independent marker of the presence of ED.

Preoperative biliary drainage of the hepatic lobe to be resected does not affect liver hypertrophy after percutaneous transhepatic portal vein embolization.

BACKGROUND: In patients with malignant perihilar biliary strictures, preoperative biliary drainage (PBD) of the hepatic lobe to be resected may decrease the liver volume of the future liver remnant (FLR) after percutaneous transhepatic portal vein embolization (PVE). However, evidence of its application is insufficient. This study aimed to clarify the effects of PBD on liver hypertrophy after PVE. METHODS: Between January 2008 and December 2017, 169 patients with malignant perihilar biliary strictures underwent major hepatectomy or palliative surgery at our hospital. Of these, 76 patients who underwent PVE were categorized into two groups: group A (n = 29) who received unilateral PBD of the FLR and group B (n = 47) who received bilateral PBD, including that of the hepatic lobe to be resected. FLR ratios after PVE and liver hypertrophy ratios were retrospectively compared in both groups. RESULTS: Group B exhibited significantly severe biliary stenosis (p = 0.0038) and high serum bilirubin before biliary drainage (p = 0.0037). After PVE, the total liver volumes were 1287 ± 260 ml and 1340 ± 257 ml (p = 0.39), respectively. FLR volumes were 555 ± 135 and 577 ± 113 ml (p = 0.45), respectively. FLR ratios were 43.4 ± 8.2% and 43.4 ± 6.4%, respectively (p = 0.98). Liver hypertrophy ratios were 124.2 ± 17.7% and 129.2 ± 20.9%, respectively (p = 0.28). In addition, an examination which excluded patients with Bismuth type I obtained similar result. CONCLUSIONS: PBD of the hepatic lobe to be resected did not decrease the FLR ratios and hypertrophy ratios. Thus, in patients with poor biliary drainage, additional PBD of the target lobe is acceptable.

Impact of visit-to-visit variability in blood pressure on coronary plaque as assessed by integrated backscatter intravascular ultrasound.

INTRODUCTION: Visit-to-visit variability (VVV) in blood pressure (BP) has been reported to be a strong predictor of cardiovascular disease. However, the association between VVV in BP and coronary plaque composition has not been fully elucidated. METHODS: One hundred-two consecutive patients with coronary artery disease (CAD) who underwent percutaneous coronary intervention (PCI) using integrated backscatter (IB) intravascular ultrasound (IVUS), and who had at least six clinic visits a year before PCI were included. We measured systolic and diastolic BP (SBP and DBP) at each visit and determined VVV in BP expressed as the standard deviation of the average BP. Grayscale and IB IVUS examinations were performed for the culprit lesion of a coronary artery just before PCI. RESULTS: There were no significant associations between the average SBP or DBP and various IVUS parameters. However, VVV in SBP was positively correlated with both the percentage (%) of atheroma volume (ß = 0.23, p = .02) and % lipid volume (ß = 0.53, p < .0001). VVV in DBP was positively correlated with % lipid volume (ß = 0.24, p = .01), while there was no significant correlation between VVV in DBP and % atheroma volume. A  multivariable linear regression analysis showed that VVV in SBP was independently associated with % atheroma volume (p = .04) and % lipid volume (p < .001). CONCLUSIONS: Larger VVV in SBP was significantly associated with an increased plaque burden and lipid composition at the culprit lesion of a coronary artery in CAD patients. The improvement of VVV in SBP may contribute to the regression and stabilization of coronary plaques.

New-Onset or Exacerbation of Diabetes Mellitus Is a Clue to the Early Diagnosis of Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC), which accounts for majority of pancreatic cancers, is one of the most lethal human malignancies. Most patients are diagnosed at an advanced stage after symptom development. Early diagnosis of PDAC in asymptomatic subjects is important to improve prognosis. Diabetes mellitus (DM) is a risk factor for PDAC, and DM, especially new-onset DM, has attracted attentions as a diagnostic clue to PDAC. However, the impact of DM as a diagnostic opportunity on the prognosis of PDAC is unclear. We here retrospectively reviewed 489 PDAC patients and compared the clinical characteristics and prognosis according to the opportunities for PDAC diagnosis. PDAC was diagnosed upon presentation of symptoms, such as pain and jaundice, in 318 cases including 151 DM patients, upon new-onset or exacerbation of long-standing DM in 53 asymptomatic patients, and upon incidental detection by medical check-up or follow-up/work-up of other diseases in 118 asymptomatic patients. Asymptomatic patients including those with DM had smaller tumors, earlier disease stage, and higher resectability rates than symptomatic patients. Asymptomatic patients diagnosed in association with DM had better prognosis (median survival time, 771 days) than those diagnosed due to symptoms (343 days, P < 0.001), and similar to those diagnosed by incidental detection (869 days). The survival advantage was not evident in symptomatic patients with DM-associated signs. In conclusion, patients diagnosed in association with DM at asymptomatic stages had better prognosis than those diagnosed with symptoms. DM-associated signs might provide a clue to the early diagnosis of PDAC among asymptomatic subjects.
