Mac-2 binding protein glycosylation isomer as a novel predictor of early recurrence after resection for hepatocellular carcinoma.

PURPOSE: Hepatocellular carcinoma (HCC) frequently recurs after radical resection, resulting in a poor prognosis. This study assessed the prognostic value of Mac-2 binding protein glycosylation isomer (M2BPGi) for early recurrence (ER) in patients with HCC. METHODS: Patients who underwent radical resection for HCC between 2015 and 2021. HCC recurrence within one year after curative resection was defined as ER. RESULTS: The 150 patients were divided into two groups: non-ER (116, 77.3%) and ER (34, 22.7%). The ER group had a lower overall survival rate (p < 0.0001) and significantly higher levels of M2BPGi (1.06 vs. 2.74 COI, p < 0.0001) than the non-ER group. High M2BPGi levels (odds ratio [OR] 1.78, 95% confidence interval [CI] 1.31-2.41, p < 0.0001) and a large tumor size (OR 1.31, 95% CI, 1.05-1.63; p = 0.0184) were identified as independent predictors of ER. M2BPGi was the best predictor of ER according to a receiver operating characteristic (ROC) analysis (area under the ROC curve 0.82, p < 0.0001). CONCLUSIONS: M2BPGi can predict ER after surgery and is useful for risk stratification in patients with HCC.

Phase II clinical trial to study the safety and efficacy of combined S-1 + oxaliplatin therapy as neoadjuvant chemotherapy for locally advanced gastric cancer in older patients.

BACKGROUND: Gastrectomy with D2 dissection and adjuvant chemotherapy is the standard treatment for locally advanced gastric cancer (LAGC) in Asia. However, administering chemotherapy with sufficient intensity after gastrectomy is challenging. Several trials demonstrated the efficacy of neoadjuvant chemotherapy (NAC). However, limited studies explored the feasibility of NAC-SOX for older patients with LAGC. This phase II study (KSCC1801) evaluated the safety and efficacy of NAC-SOX in patients with LAGC aged ≥ 70 years. METHODS: Patients received three cycles of SOX130 (oxaliplatin 130 mg/m2 on day 1, oral S-1 40-60 mg twice daily for two weeks every three weeks) as NAC, followed by gastrectomy with lymph node dissection. The primary endpoint was the dose intensity (DI). The secondary endpoints were safety, R0 resection rate, pathological response rate (pRR), overall survival, and relapse-free survival. RESULTS: The median age of 26 enrolled patients was 74.5 years. The median DI in NAC-SOX130 was 97.2% for S-1 and 98.3% for oxaliplatin. Three cycles of NAC were administered in 25 patients (96.2%), of whom 24 (92.3%) underwent gastrectomy with lymphadenectomy. The R0 resection rate was 92.3% and the pRR (≥ grade 1b) was 62.5%. The major adverse events (≥ grade 3) were neutropenia (20.0%), thrombocytopenia (11.5%), anorexia (11.5%), nausea (7.7%), and hyponatremia (7.7%). Postoperative complications of abdominal infection, elevated blood amylase, and bacteremia occurred in one patient each. Severe diarrhea and dehydration caused one treatment-related death. CONCLUSIONS: NAC-SOX130 is a feasible therapy for older patients, although systemic management and careful monitoring of adverse events are necessary.

A novel combined carbohydrate antigen 19-9 and lymphocyte-to-monocyte ratio score can predict early recurrence of resectable pancreatic ductal adenocarcinoma.

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) often recurs early after radical resection, which causes a poor prognosis. This study aimed to establish a scoring model to assess the optimal treatment in patients who underwent surgery for PDAC. METHODS: This single-center retrospective study included 127 patients who underwent radical resection for PDAC between 2005 and 2021. Early recurrence (ER) was defined as recurrence within 12 months after resection. The predictive effect for ER was evaluated using receiver operating characteristic (ROC) curves of preoperative parameters. RESULTS: ER occurred in 43 (33.9%) patients. The ER group had a significantly worse prognosis than the non-ER group (p < 0.0001). The carbohydrate antigen 19-9 (CA19-9) level and lymphocyte-to-monocyte ratio (LMR) were the strongest diagnostic factors (areas under the ROC curves: 0.74 and 0.68, respectively). The ER prediction score was calculated using optimal cutoff values. A higher CA19-9-LMR score was associated with a worse prognosis in terms of the overall and recurrence-free survival (p = 0.0017 and p < 0.0001, respectively). A multivariate analysis identified a high CA19-9-LMR score as an independent predictor of ER. CONCLUSIONS: The CA19-9-LMR scoring model can predict ER after surgery and is applicable for risk stratification in the assessment of patients with resectable PDAC.

Evaluation of the Antihypertensive Activity of Eggplant Acetylcholine and γ-Aminobutyric Acid in Spontaneously Hypertensive Rats.

Daily consumption of eggplant powder containing 2.3 mg acetylcholine (ACh) is known to alleviate hypertension and improve mental status. However, eggplant powder used in clinical trials also contains the antihypertensive compound γ-aminobutyric acid (GABA). Although our previous study indicated that the main antihypertensive compound in eggplant is ACh, given that GABA amounts in eggplant do not reach the effective dosage, the effects of GABA on the antihypertensive effect of eggplant remain unclear. It is necessary to establish whether there is a synergistic effect between GABA and ACh and whether GABA in eggplant exerts antihypertensive effects. Consequently, here we sought to evaluate the effects of GABA on the antihypertensive effects of eggplant. We used a probability sum (q) test to investigate the combined effects of ACh and GABA and prepared eggplant powder with very low ACh content for oral administration in animals. ACh and GABA exhibited additive effects but the GABA content in eggplants was not sufficient to promote a hypotensive effect. In conclusion, ACh is the main component associated with the antihypertensive effects of eggplant but GABA within eggplants has a minimal effect in this regard. Thus, compared with GABA, ACh could be a more effective functional food constituent for lowering blood pressure.

[A case of retrograde intussusception due to transverse colon cancer detected by abdominal ultrasonography].

A 78-year-old female patient presented to our hospital with abdominal pain and melena. Abdominal ultrasonography detected a multiple concentric ring sign and retrograde invagination mass near the hepatic flexure. Colonoscopy revealed a 40-mm diameter type 1 tumor in the transverse colon near the splenic flexure, and the biopsy specimen demonstrated a well-differentiated adenocarcinoma. Retrograde intussusception due to transverse colon cancer was diagnosed, and laparoscopic transverse colon resection with lymph node dissection was performed. The resected specimen revealed a 48×40mm diameter type 1 tumor in the transverse colon and was diagnosed as pT2N0M0 pStage I. Contrast-enhanced computed tomography was unavailable, but real-time assessment of the invaginated mass and bowel blood flow was possible by abdominal ultrasonography, which was useful in determining the diagnosis and treatment strategy.

Mac-2-Binding Protein Glycosylation Isomer as a Novel Predictor of Hepatocellular Carcinoma Recurrence in Patients with Hepatitis C Virus Eradication.

BACKGROUND: Hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) can recur even after achievement of a sustained virologic response (SVR). Mac-2-binding protein glycosylation isomer (M2BPGi) is a newly identified biomarker correlated with liver fibrosis. This study aimed to clarify outcomes for patients with an SVR and to assess the prognostic value of M2BPGi. METHODS: This single-center retrospective study analyzed patients who underwent surgical resection for primary HCV-related HCC between 2008 and 2018. The study enrolled 81 patients whose M2BPGi could be evaluated after an SVR. The relationship between liver fibrosis-related factors and scores (including M2BPGi) and HCC recurrence, was evaluated. RESULTS: Of the 81 patients, 57 (70.4%) with HCV-related HCC obtained an SVR, whereas 24 patients (29.6%) did not. The patients with an SVR had a significantly more favorable recurrence-free survival (RFS) than the patients with no SVR (P < 0.0001, log-rank). Among the SVR groups, M2BPGi predicted a shorter RFS after hepatic resection with a higher degree of accuracy than other markers and scores in the SVR group. The high-M2BPGi group had worse liver function, RFS, and overall survival (OS) (P = 0.0014 and 0.0006, log-rank, respectively). In the multivariate analysis, high M2BPGi was significantly associated with worse RFS and OS. CONCLUSIONS: Even after achievement of an SVR, the risk of HCC recurrence cannot be eliminated. Measurement of M2BPGi after an SVR can be applied for risk stratification in the assessment of patients with HCV-related HCC.

Impact of aspartate aminotransferase-to-platelet ratio index based score to assess posthepatectomy liver failure in patients with hepatocellular carcninoma.

BACKGROUND: Posthepatectomy liver failure (PHLF) is a life-threatening complication following hepatic resection. The aspartate aminotransferase-to-platelet ratio index (APRI) is a non-invasive model for assessing the liver functional reserve in patients with hepatocellular carcinoma (HCC). This study aimed to establish a scoring model to stratify patients with HCC at risk for PHLF. METHODS: This single-center retrospective study included 451 patients who underwent hepatic resection for HCC between 2004 and 2017. Preoperative factors, including non-invasive liver fibrosis markers and intraoperative factors, were evaluated. The predictive impact for PHLF was evaluated using receiver operating characteristic (ROC) curves of these factors. RESULTS: Of 451 patients, 30 (6.7%) developed severe PHLF (grade B/C). Multivariate logistic analysis indicated that APRI, model for end-stage liver disease (MELD) score, operating time, and intraoperative blood loss were significantly associated with severe PHLF. A scoring model (over 0-4 points) was calculated using these optimal cutoff values. The area under the ROC curve of the established score for severe PHLF was 0.88, which greatly improved the predictive accuracy compared with these factors alone (p < 0.05 for all). CONCLUSIONS: The scoring model-based APRI, MELD score, operating time, and intraoperative blood loss can predict severe PHLF in patients with HCC.

A novel combined prognostic nutritional index and aspartate aminotransferase-to-platelet ratio index-based score can predict the survival of patients with hepatocellular carcinoma who undergo hepatic resection.

PURPOSE: Inflammation-, nutrition-, and liver fibrosis-related markers are recognized as prognostic for hepatocellular carcinoma (HCC) patients. This study, therefore, assessed the preoperative prognostic utility of the combination of these markers in patients with HCC. METHODS: This single-center retrospective study included patients who underwent hepatic resection for HCC between 2004 and 2017. A total of 454 patients were divided into training (n = 334) and validation (n = 120) cohorts by random sampling. The predictive impact on surgical outcomes was evaluated using receiver operating characteristic (ROC) curves of these prognostic values in the training cohort. RESULTS: The prognostic nutritional index (PNI) and aspartate aminotransferase-to-platelet ratio index (APRI) were the strongest diagnostic values (areas under the ROC curves: 0.627 and 0.646, respectively). A scoring system (over 0-2 points) was developed using optimal cutoff values (for PNI < 46.5 scored as 1 point; for APRI > 0.98 scored as 1 point). An increased PNI-APRI score was an independent prognostic factor for both the overall and disease-free survival in HCC patients. Finally, the clinical feasibility of the PNI-APRI score was confirmed in the validation cohort. CONCLUSIONS: The PNI-APRI score is a useful marker for predicting surgical outcomes of HCC patients.

Adsorption of the Cationic Dye Methylene Blue on Anodic Porous Alumina in Sodium Dodecyl Sulfate Solutions.

Dyeing of anodic porous alumina (APA) prepared by aluminum anodization is generally achieved by dipping the positively charged APA surface into a negatively charged dye solution. We have proposed a new method to adsorb dyes and molecules onto APA using negatively charged sodium dodecyl sulfate (SDS). In this study, we found that cationic methylene blue (MB) can be adsorbed onto the positively charged APA surface using SDS aqueous solutions. We investigated two adsorption methods: dipping APA into aqueous solutions containing both MB and SDS (method 1) and successive dipping of APA into SDS and then MB aqueous solutions (method 2). The two methods produced different adsorption characteristics. Method 1 adsorption profile reflected formation of dye-rich induced micelles below the critical micellar concentration (CMC) and electrostatic interaction of micelles with MB above CMC. Method 2 adsorption was explained by electrostatic interaction of preadsorbed SDS with APA and MB.

Long-Term Outcome of Definitive Chemoradiotherapy and Induction Chemoradiotherapy Followed by Surgery for T4 Esophageal Cancer with Tracheobronchial Invasion.

BACKGROUND: T4 esophageal cancer (EC) that invades the trachea or bronchus often has poorer prognosis than other T4 ECs. We investigated the long-term results of definitive chemoradiotherapy (dCRT) or induction chemoradiotherapy followed by surgery (iCRT-S) in patients with T4 EC with tracheobronchial invasion (TBI). PATIENTS AND METHODS: From 2003 to 2013, 71 patients with T4 EC with TBI were treated in our institution; 58 underwent dCRT, and 13 underwent iCRT-S. The long-term results associated with survival were retrospectively analyzed, and prognostic factors were examined by univariable and multivariable analysis. RESULTS: The 1-, 2-, and 5-year overall survival for all patients with T4 EC with TBI treated by dCRT or iCRT-S was 57, 29, and 19%, respectively. Multivariable analysis revealed that clinical lymph node (LN) metastasis and the treatment period were significant prognostic factors. Clinical LN positivity had significantly poorer prognosis than LN negativity. The treatment outcome in the later period was significantly better than that in the earlier period. In particular, the outcome after dCRT revealed significantly better prognosis in the later compared with the earlier period, whereas the outcome after iCRT-S did not show such a difference. With respect to treatment modality, no significant difference in survival was observed between dCRT and iCRT-S. CONCLUSIONS: Clinical LN negativity and later treatment period were significantly good prognostic factors for T4 EC with TBI. The recent improvements in dCRT outcomes may help to achieve survival comparable to that of iCRT-S.

Decreased Fatty Acid ß-Oxidation Is the Main Cause of Fatty Liver Induced by Polyunsaturated Fatty Acid Deficiency in Mice.

Insufficient intake of polyunsaturated fatty acids (PUFA) causes fatty liver. The mechanism responsible is primarily related to increased lipogenesis and decreased FA degradation based on rodent studies. However, these studies were limited by the fact that the typical PUFA-deficient diets contained insufficient amounts of long-chain FA, the PUFA-containing diets were primarily composed of n-3 PUFA-enriched oil, and the intake of PUFA was excessive compared with the physiological requirement. To address these issues, mice were fed a PUFA-deficient diet containing long-chain FA at a standard fed level and then were orally fed a n-3/n-6-balanced PUFA-containing oil [PUFA (+)] or a PUFA-deficient oil [PUFA (-)] at physiological relevant levels (0.1 mL/mouse/2d). We compared these groups and examined whether fatty liver in PUFA deficiency was attributable to both the effects of increased lipogenesis and decreased FA catabolism. Compared with the PUFA (+) group, the PUFA (-) group showed increases in liver triglyceride and serum FA content. Hepatic gene expression of several mitochondrial ß-oxidation enzymes, the serum 3-hydroxybutyrate level, and DNA-binding ability of peroxisome proliferator-activated receptor α (PPARα) were increased in the PUFA (+) group, whereas these adaptive responses were significantly attenuated in the PUFA (-) group. The hepatic expression of typical lipogenesis genes did not differ between the groups. Therefore, fatty liver in PUFA deficiency is attributable to suppression of the FA-degrading system probably from decreased PPARα adaptive responsiveness, and PUFA may be an essential factor for PPARα functioning. This finding is helpful for managing clinical situations having a risk of PUFA deficiency.

S-1 Adjuvant Chemotherapy Earlier After Surgery Clinically Correlates with Prognostic Factors for Advanced Gastric Cancer.

BACKGROUND: S-1 adjuvant chemotherapy is commonly administered postoperatively for stage II and III advanced gastric cancer. METHODS: This study included 113 patients treated with S-1 adjuvant chemotherapy after surgery for stage II and III advanced gastric cancer. These patients were divided into 4 groups: group A (n = 63), who had a longer duration (≥6 months) and earlier S-1 administration (≤6 weeks) after surgery; group B (n = 16), who had a longer and later S-1 administration (>6 weeks) after surgery; group C (n = 27), who had a shorter duration (<6 months) and earlier S-1 administration after surgery; and group D (n = 7), who had a shorter and later S-1 administration after surgery. RESULTS: The recurrence rates in groups A, B, C, and D were 15.7, 43.8, 44.4, and 57.1 %, respectively (A vs. B, p < 0.05, A vs. C and D, p < 0.01). The survival time of group A was significantly longer than that of other groups (p < 0.005). In addition, the survival time of patients with severe complications was significantly shorter than that of patients with non-severe complications (p < 0.05). An earlier S-1 administration after surgery was the only independent prognostic factor in the multivariate analysis. CONCLUSIONS: The prognosis of advanced gastric cancer was significantly related to the start of S-1 adjuvant treatment within 6 weeks after surgery.

Hepatic resection of hepatocellular carcinoma after proton beam therapy: A case report.

Despite the widespread use of proton beam therapy (PBT) as locoregional therapy, there is currently a lack of histological evidence about the therapeutic effect of PBT for hepatocellular carcinoma (HCC). We present a case of hepatectomy and histological examination of HCC initially treated by PBT. A 76-year-old man with chronic hepatitis C underwent routine ultrasound surveillance, which revealed a 22-mm HCC in segment 4 of the liver. His hepatic reserve was adequate for surgical resection of the tumor; however, he chose to undergo PBT because of his cardiac disease. The patient received 66 Gy in 10 fractions with no toxicity exceeding grade 1. Six months after completion of PBT, contrast computed tomography showed that the tumor had increased in size to 27 mm, and the marginal part of the tumor, but not the central region, was enhanced. Additionally, two new hypervascular nodules were present in segments 5 and 6. The patient underwent surgical treatment 7 months after PBT. The operation and postoperative clinical course were uneventful. Nine months later, however, computed tomography demonstrated new, small, enhanced nodules in the remnant liver (segments 3, 5 and 6) and sacrum. In conclusion, PBT is a valuable treatment for HCC; however, it is difficult to evaluate therapeutic effect of HCC during the early post-irradiation period and provide an alternative treatment if PBT is not effective, especially in HCC cases with good liver function.

Significance of preoperative evaluation of the right gastroepiploic artery graft to the coronary artery in patients undergoing abdominal surgery.

BACKGROUND: A major concern with the use of the right gastroepiploic artery (RGEA) as the graft for coronary artery bypass grafting (CABG) is the potential for injury, which can result in critical myocardial ischemia during future abdominal surgery. METHODS: We examined the availability of preoperative image evaluation, preoperative recognition of the RGEA graft, and operative findings such as graft identification, graft injury, and cardiac events in 11 patients who underwent abdominal surgery after CABG using the RGEA as the graft. RESULTS: Prior to the abdominal surgery, contrast-enhanced computed tomography (CT) was performed in all 11 patients, while coronary angiography or three-dimensional CT angiography was performed in five patients. We detected the RGEA graft retrospectively in nine of ten patients in whom the images from contrast-enhanced CT were still available. Among the seven patients whose RGEA grafts were in the operative field, the RGEA graft was identified in five patients, while the RGEA graft was not identified in the remaining two patients because of adhesions. There were no intraoperative cardiac events in any of the 11 patients. CONCLUSIONS: It is important to determine whether an RGEA graft is present when repeat laparotomy is required after CABG. In cases where an RGEA graft is present, it is essential to evaluate the patency and location of the graft since this will be crucial for planning the reoperation strategy. Preoperative recognition and evaluation of the RGEA graft can help avoid graft injury, even if the graft cannot be detected intraoperatively.

A case of difficult-to-diagnose hepatic reactive lymphoid hyperplasia finally diagnosed by using PCR analysis of IgH-gene rearrangements: a case report.

Reactive lymphoid hyperplasia (RLH) of the liver is extremely rare. Despite advancements in diagnostic imaging technology, it is still difficult to distinguish from hepatocellular carcinoma (HCC). Herein, we present a case of hepatic RLH mimicking HCC that was postoperatively diagnosed using several imaging modalities. A 78-year-old female was referred to our hospital with a positive hepatitis C virus antibody (HCV Ab) test. Ultrasonography revealed a 13 mm isoechoic lesion in segment 8 of the liver. Contrast-enhanced computed tomography (CE-CT) demonstrated arterial hyperintensity and washout during the later phase. On ethoxybenzyl magnetic resonance imaging (EOB-MRI), the lesion was hyperenhanced in the arterial phase and of low intensity in the hepatocyte phase. Although the tumor markers were all within normal limits, the pattern of contrast enhancement of the tumor on CT and MRI was consistent with that of HCC. We performed S8 segmentectomy of the liver. Histological examination of the resected specimen revealed dense lymphoid tissue of variable sizes and shapes with expanded germinal centers. Immunohistochemical examination was positive for CD3, CD10 (germinal center), and CD20, and negative for B-cell lymphoma 2 (bcl-2) (germinal center) and Epstein-Barr virus (EBV). A polymerase chain reaction (PCR) analysis of IgH-gene rearrangements revealed polyclonality. Based on these findings, hepatic RLH was diagnosed. The postoperative course was uneventful, and the patient was discharged on the 10th postoperative day. She had a good quality of life after surgery and no liver nodule recurrence was detected at the 4-month medical follow-up. Hepatic RLH is an extremely rare disease and preoperative diagnosis is difficult. This should be considered in the differential diagnosis of single small hepatic tumors. An echo-guided biopsy and careful observation of imaging may help diagnose hepatic RLH, and a PCR analysis of IgH-gene rearrangements would be necessary for the definitive diagnosis of hepatic RLH.

Skeletal Muscle Mass Index Reduction Rate as a Prognostic Indicator for Patients Undergoing Pancreatectomy for Pancreatic Cancer.

Background/Aim: There have been many studies on skeletal muscle depletion before surgery, and skeletal muscle depletion is a known risk factor for poor prognosis. However, reports on the association between changes in skeletal muscle mass and prognosis after surgery for pancreatic cancer are very few. Patients and Methods: The data of 137 patients who underwent pancreatectomy for pancreatic cancer between 2005 and 2022 were reviewed. Muscle areas were measured at the third lumbar vertebral level, and skeletal muscle mass index (SMI) reduction rates were calculated. Patients were divided into two groups using receiver operating characteristic (ROC) curve analysis based on the SMI reduction rate with a cutoff of 14% reduction rate. The clinicopathological factors, overall survival (OS), and recurrence-free survival (RFS) were compared between the two groups. Survival rates were analyzed both univariately and multivariately to clarify the factors associated with poor prognosis after pancreatectomy. Results: A total of 102 patients met the inclusion criteria. SMI reduction rate ≥14% significantly correlated with advanced age and higher incidence of postoperative complications. In the multivariate Cox regression analysis, preoperative prognostic nutritional index (PNI) <40 and SMI reduction rate ≥14% were significantly associated with poor OS. Tumor size ≥3.0 cm, preoperative neutrophile-lymphocyte ratio ≥3.0, and SMI reduction rate ≥14% were significantly associated with poor RFS. Conclusion: The rate of skeletal muscle mass reduction after pancreatic surgery is an independent prognostic factor for survival in patients with pancreatic cancer.

Lumbar hernia treated with lightweight partially absorbable mesh: report of a case.

Superior lumbar hernia, also known as Grynfeltt-Lesshaft hernia, is an uncommon abdominal wall defect. We report a case of superior lumbar hernia, which was successfully treated with a lightweight partially absorbable mesh. A 73-year-old man visited our department with complaints of lumbar pain and a feeling of pressure associated with a right lumbar mass. A CT scan of the abdomen demonstrated a defect in the aponeurosis of the transversus abdominis muscle and a protrusion of the small intestine through the defect. The diagnosis of a right superior lumbar hernia was made. The lumbar hernia was surgically treated with a lightweight large-pore polypropylene mesh containing an absorbable component consisting of poliglecaprone (ULTRAPRO Plug). The patient had no evidence of recurrence after 4 years of follow-up without any sense of discomfort. This is the first case report of a lumbar hernia treated with a lightweight partially absorbable mesh. This partially absorbable mesh can be considered to be suitable for the treatment of a lumbar hernia.

Antihypertensive and Vasorelaxant Effects of Citric Acid and Lemon Juice in Spontaneously Hypertensive Rats: In Vivo and Ex Vivo Studies.

Hypertension is a key risk factor for heart, brain, and kidney disease development. Fruit consumption has been associated with a decrease in blood pressure. Lemon juice, which contains antihypertensive compounds, may exert antihypertensive effects. However, no research has verified the antihypertensive effects of citric acid, the most abundant ingredient in lemon juice. In the present study, we demonstrated the antihypertensive effects of citric acid and lemon juice by performing single oral administration tests and the aortic ring assay using spontaneously hypertensive rats (SHRs). Single oral doses of both agents markedly reduced the systolic and diastolic blood pressures in the SHRs. In addition, both these agents relaxed the thoracic aorta from the SHRs; however, these effects were notably attenuated by the removal of the aortic endothelium. Orally administered citric acid was rapidly absorbed and metabolized in vivo. Among the functional compounds in lemon juice, citric acid was identified as the primary antihypertensive component. Although more detailed studies are required to validate our findings, the novel functional attributes of citric acid can achieve the normalization of blood pressure when it is consumed via diet.

Total pancreatectomy preserving the right gastroepiploic artery following proximal gastrectomy.

Total pancreatectomy (TP) after proximal gastrectomy (PG) requires more attention than ordinary TP during surgery in terms of the preservation of blood flow to the remnant stomach that was supplied via only the right gastric and gastroepiploic arteries. The current report presents the details of a case in which the remnant stomach was safely preserved when performing TP. A 74-year-old man who underwent PG for gastric cancer 17 years previously was diagnosed with pancreatic head cancer during follow-up for intraductal papillary mucinous neoplasm of the pancreatic body and tail. To preserve digestive function and reduce postoperative complications, TP preserving the right gastroepiploic artery and splenic vessels was performed. The remnant stomach and function were safely preserved without any complications after surgery.

Prognostic Impact of a Novel Albumin-Platelet Index as Selection Criterion for Hepatic Resection in Intermediate Stage Hepatocellular Carcinoma.

BACKGROUND/AIM: Hepatic resection for Barcelona Clinic Liver Cancer (BCLC) stage B (intermediate-stage) hepatocellular carcinoma (HCC) is not recommended by BCLC treatment algorithms. We sought to develop a new prognostic model for determining appropriate treatment strategies in patients with intermediate-stage HCC. PATIENTS AND METHODS: This single-center retrospective study included patients who underwent hepatic resection for HCC between 2000 and 2018. A total of 498 patients were classified according to the BCLC staging system (0, n=116; A, n=319; B, n=63). The predictive impact for surgical outcomes was evaluated using receiver operating characteristic (ROC) curves. Based on a survival outcome probability formula, a new predictive model was established. RESULTS: The preoperative albumin level and platelet count were the strongest diagnostic values in patients with intermediate-stage HCC (areas under the ROC curves, AUCs: 0.710 and 0.676, respectively). Logistic regression analysis provided the albumin-platelet index [API; 156.2×albumin (g/dl)+platelet count (×109/l)] was defined as a new prognostic model for the probability of poor survival. The optimal cutoff value (781.2; AUC 0.755) divided patients with BCLC-B into B1 (>781.2, n=27) and B2 (≤781.2, n=36) categories. Patients in substage B2 had a significantly worse prognosis than patients in other stages (p<0.0001), whereas there was no difference in prognosis between patients in substage B1 and those in other stages. CONCLUSION: The API stratifies prognosis in patients with intermediate-stage HCC. For subgroup B1, hepatic resection can be considered a radical treatment, even for intermediate-stage HCC.
