Screening performance of a 100-mL water swallowing test in community-dwelling older adults: A receiver operating characteristic analysis.

OBJECTIVE: The development of a dysphagia screening test is an urgent issue in the field of frailty prevention among community-dwelling older people. The purpose of this study was to evaluate the screening performance of a 100-mL water swallowing test (WST). METHODS: The study employed a cross-sectional design. Participants were 304 (65 men and 239 women, mean age = 80 years) Japanese community-dwelling older adults aged over 65 years. We investigated swallowing disorder using the 10-item Eating Assessment Tool (EAT-10), and compared choking signs, swallowing time and number of swallows, and their combination in the 100-mL WST. We calculated the sensitivity and specificity of these indices. Receiver operating characteristic (ROC) curve analysis was used to determine the optimal cut-off value of swallowing time and number of swallows in the 100-mL WST based on the Youden Index among participants without choking signs. RESULTS: The sensitivity and specificity of choking signs in the 100-mL WST were 20% and 91%, respectively. The discriminating ability of swallowing time and number of swallows among participants without any choking signs was .76 and .72, respectively, in the area under the ROC curve. Diagnostic sensitivity and specificity to discriminate dysphagia from normal swallowing ability were 65% and 74% when the cut-off was >10 s based on maximisation of the Youden Index. The 100-mL WST performed best when the indices of choking signs and swallowing time were combined, with a sensitivity and specificity of 72% and 68%, respectively. CONCLUSIONS: The 100-mL WST would be an adequate screening tool when compared to the EAT-10.

Impact of visitation restrictions on the mental health of family caregivers during the COVID-19 pandemic: A mixed methods study.

AIM: To examine the mental health conditions of family caregivers residing away from their loved ones who experienced visitation restrictions during the coronavirus disease 2019 pandemic. DESIGN: A mixed-methods design applying the Kessler Scale-10 for the quantitative measurement of psychological distress and an open-ended question for qualitative analysis. METHODS: The participants were recruited from care facilities between February and September 2021. This cross-sectional study included 197 family caregivers who were utilizing formal residential care services for their loved ones. Using thematic analyses, open-ended responses regarding the impact of visitation restrictions were coded. These themes were then examined to determine thematic patterns across caregiver characteristics. RESULTS: Thirteen themes were identified regarding the impact of visitation restrictions. Many participants reported primary harmful effects as follows: 'inability to confirm the type of care and lifestyle assistance provided to an older relative' and 'difficulty communicating with an older relative because of the inability to converse face-to-face'. Younger age, being employed, poor sleep, poor relationship quality with the care recipient and experiencing harmful effects from the visitation restrictions were associated with psychological distress. CONCLUSION: Our findings suggest that to maintain positive mental health after a care transition, it is important for family caregivers to take part in the care of their loved ones and ensure information sharing between the care recipient's family and institution. IMPACT: These findings suggest that both residents and family caregivers living outside facilities may feel distressed due to separation. Therefore, institutional care staff needs to consider how to adjust facility procedures or communication with family caregivers. PATIENT OR PUBLIC CONTRIBUTION: The comments obtained from the participants in this survey helped to shape the study design and are expected to contribute to the further development of quality facility care.

The Combination of Binding Avidity of Ovomucoid-Specific IgE Antibody and Specific IgG4 Antibody Can Predict Positive Outcomes of Oral Food Challenges during Stepwise Slow Oral Immunotherapy in Children with Hen's Egg Allergy.

To increase the prediction accuracy of positive oral food challenge (OFC) outcomes during stepwise slow oral immunotherapy (SS-OIT) in children with a hen's egg (HE) allergy, we evaluated the predictive value of the combination of antigen-specific IgE (sIgE) with antigen binding avidity and sIgG4 values. Sixty-three children with HE allergy undergoing SS-OIT were subjected to repeated OFCs with HE. We measured the ovomucoid (OVM)-sIgE by ImmunoCAP or densely carboxylated protein (DCP) microarray, sIgG4 by DCP microarray, and the binding avidity of OVM-sIgE defined as the level of 1/IC50 (nM) measured by competitive binding inhibition assays. The OFC was positive in 37 (59%) patients undergoing SS-OIT. Significant differences in DCP-OVM-sIgE, CAP-OVM-sIgE, I/IC50, DCP-OVM-sIgG4, the multiplication products of DCP-OVM-sIgE, and the binding avidity of DCP-OVM-sIgE (DCP-OVM-sIgE/IC50) and DCP-OVM-sIgE/sIgG4 were compared between the negative and positive groups (p < 0.01). Among them, the variable with the greatest area under the receiver operating characteristic curve was DCP-OVM-sIgE/IC50 (0.84), followed by DCP-OVM-sIgE/sIgG4 (0.81). DCP-OVM-sIgE/IC50 and DCP-OVM-sIgE/sIgG4 are potentially useful markers for the prediction of positive OFCs during HE-SS-OIT and may allow proper evaluation of the current allergic status in the healing process during HE-SS-OIT.

Intake of allergenic foods at 1.5 years and 3 years of age in a general child population in Japan: a cross-sectional study.

BACKGROUND: Recent studies indicate that the timing of introduction of potentially allergenic food is crucial for the development of food allergy in children. This cross-sectional study aimed to clarify the reality of allergen food intake in a general population of young children in Japan. METHODS: A questionnaire survey of caregivers was conducted at health checkups for 1.5-year (18-month)-old and 3-year-old children in the fall of 2020. The caregivers were asked about (1) the presence/absence of allergic disease symptoms based on the ISAAC questionnaire, and (2) foods that caregivers avoided giving their children. Ordinal logistic regression analyses were periformed to determine factors associated with food avoidance. RESULTS: Questionnaires were distributed to 1720 caregivers, and 1603 (93%) responded. The responders consisted of 771 and 832 caregivers who participated in 1.5-year-old and 3-year-old checkups, respectively. The prevalence of allergic diseases was comparable to recent epidemiological studies in Japan, indicating that the population may be representative. At 1.5 years old, more than 50% of the children were not exposed to peanuts, tree nuts, fish eggs, shellfish, and buckwheat. At 3 years old, the avoidance rates of the foods had decreased but were still between 18.8% and 32.0%. On the other hand, the avoidance rates of chicken egg and cow's milk, the top 2 common allergenic foods in Japan, were much lower at 2.8% and 1.5% at 1.5 years, and they decreased to 1.4% and 0.7% at 3 years old, respectively. Ordinal logistic analysis showed that avoidance of chicken egg, cow's milk, and wheat was associated with food allergy diagnosis and chicken egg avoidance with eczema, but avoidance of other foods showed no associations with any risk factors for food allergy. CONCLUSION: Caregivers avoided giving various foods, independent of allergy risk factors, to their young children. Since delayed introduction of an allergenic food has been reported to increase the risk of developing an allergy to the food, the results warrant future investigation of the development of food allergies in relation to current eating habits and recommendations.

[Analysis of Prognostic Factors Considering Absolute Lymphocyte Count of Metastatic Breast Cancer Patients with Eribulin Mesylate Therapy-A Retrospective Study in a Single Institution].

Recently, a study for eribulin mesylate(ERI), which is a useful drug for metastatic and recurrent breast cancer, reported that the absolute lymphocyte count(ALC)before administration is a useful prognostic factor. We retrospectively examined whether the results were reproducible in the patients with ERI. We examined the effect of ERI on the overall survival(OS)in 21 patients with HER2-negative metastatic and recurrent breast cancer who underwent treatment with ERI at our hospital. The clinical benefit ratio(CBR)was 57.1%. The median time to treatment failure(TTF)was 5.8 months and median OS was 19.9 months, showing a positive correlation between the TTF and OS. The factors that significantly prolonged the OS in univariate analysis were the TTF(<3 months vs ≥3 months, p<0.001), NLR(<3 vs ≥3, p=0.037), and ALC(<1,000/ µL vs ≥1,000/µL, p=0.008). In the multivariate analysis, TTF and ALC were the prognostic factors. The ERI outcome at our institution was good regardless of the subtype. The results of the multivariate analysis showed that TTF and ALC were factors that prolonged OS, and patients who received ERI for >3 months had good OS. Long-term administration of ERI was assumed to affect the immune microenvironment and prolong OS. Additionally, our data showed that the lymphocyte count before ERI administration is a simple and useful prognostic factor.

A rare case of long-term survival of a patient who underwent radical operations for sextuple malignancies.

Multiple cancer patients who achieve long-term survival are sometimes encountered. Multiple carcinogenesis may occur due to genetic or environmental characteristics. We report the case of a 74-year-old woman who was diagnosed with synchronous double carcinoma of the duodenal papilla and gall bladder without clinical symptoms, who underwent postoperative follow-up for familiar adenomatous polyposis coli with multiple colonic adenocarcinomas, ileal adenocarcinoma, left urinary tract neoplasm, and left upper lobe lung adenocarcinoma. Computed tomography also showed an intraductal papillary mucinous neoplasm of the pancreas and a lesion that was suspected to be uterine body carcinoma; however, they did not show any clear malignant behavior. No metastatic lesions of either of these biliary cancers were observed. Based on preoperative diagnostic imaging, subtotal stomach preserving pancreaticoduodenectomy with gall bladder bed liver resection with D2 lymphadenectomy was planned and R0 resection was achieved. The postoperative histological diagnosis showed early carcinoma of the duodenal papilla and gall bladder pyloric gland adenoma without node metastasis. The postoperative course was uneventful and the patient had a good prognosis without tumor recurrence or new malignant lesions for two years after the last operation, without adjuvant therapy. Six metachronous carcinomas of eight different organ neoplasms were diagnosed, which is rare. This represents the first reported case of ampullary carcinoma in a patient with sextuple cancer.

A rare case of synchronous multiple primary malignancies of breast cancer and diffuse large B-cell lymphoma that responded to multidisciplinary treatment: a case report.

BACKGROUND: Multiple primary malignancies of breast cancer and diffuse large B-cell lymphoma (DLBCL) are rare. Here, we report a case of advanced breast cancer and DLBCL managed with multidisciplinary therapy preceded by surgery with a successful outcome. CASE PRESENTATION: During a medical examination, a 71-year-old woman was diagnosed with a right breast mass, enlarged lymph nodes throughout the body, and a splenic tumor. The results of the clinical examination and imaging were suggestive of widely spread breast cancer with lymph node metastasis and malignant lymphoma with systemic metastasis. The histological evaluation of the biopsied breast tissue revealed human epidermal growth factor receptor 2 (HER2)-positive breast cancer, whereas the histological evaluation of the excised inguinal lymph node revealed DLBCL. 18F-FDG PET/computed tomography was performed, and it was determined that both breast cancer and DLBCL were in an advanced stage. Thus, mastectomy was performed, and the axillary lymph nodes showed mixed metastasis of breast cancer and DLBCL. Soon after, the R-CHOP therapy was initiated (375-mg/m2 rituximab, 2-mg/m2 vincristine, 50-mg/m2 doxorubicin, 750-mg/m2 cyclophosphamide, and 125-mg methylprednisolone). After irradiation of the spleen, trastuzumab was administered for 1 year. CONCLUSIONS: We experienced a case of combined breast cancer and DLBCL, which was difficult to treat because both were in advanced stages. Thorough staging of the malignancy and discussion by a multidisciplinary team are necessary to determine the optimal treatment strategy.

Novel analysis using magnetic resonance cholangiography for patients with pancreaticobiliary maljunction.

PURPOSE: We used a novel diagnostic Fourier transform (FT) algorithm of the entire extrahepatic bile duct (EHBD) measured by magnetic resonance cholangiography (MRC) to evaluate subtle deformation of bile duct lumen, indicating the malignant potential of EHBD, in patients with pancreaticobiliary maljunction (PBMJ) and in a comparative group of controls without PBMJ. METHODS: From the workstation, the EHBD lumen was traced automatically and a 2D diagram cross section was measured at 0.5 mm-longitudinal intervals. The FT-based integrated power spectral density function value (FTPSDI) of the diameter or area (mm2 or mm4/Hz) and the phase value distribution entropy (PVDE) were also measured. RESULTS: There were 16 patients with undilated PBMJ and 7 with dilated PBMJ. The control group comprised 10 patients with a normal bile duct, 20 with bile duct carcinoma (BDC), and 1 with primary sclerosing cholangitis. Both the diameter and area of the dilated bile ducts and the ducts with early- or advanced-stage BDC were significantly greater than those of the normal duct (p < 0.05). The undilated type of PBMJ tended to have a larger FTPSDI diameter than a normal bile duct, which had a smaller diameter than the dilated type of PBMJ or BDC. BDC had a significantly larger FTPSDI diameter (p < 0.05) and the cutoff value for accuracy was 168 mm2 Hz-1. CONCLUSION: The novel mathematical FTPSDI is a promising indicator of whether preventive EHBD resection is necessary for patients with PBMJ, which can be widely applied in the early diagnosis of other biliary diseases.

[A Case Report of Transverse Colon Cancer with Large Abdominal Wall Abscess].

A 65-year-old woman presented to the emergency outpatient department with a chief complaint of left hypochondriac pain and a rapidly expanding tumor mass. Abdominal contrast-enhanced computed tomography(CT)revealed a tumor in the transverse colon and an extensive abdominal wall abscess. A colonoscopy further confirmed a tumor in the transverse colon, and the patient was diagnosed with transverse colon cancer, abdominal wall infiltration, and abdominal wall abscess. Abscess drainage was performed, and abscess cavity shrinkage was noted. Infection control progressed favorably. A transverse colectomy was performed, and the abdominal wall of the infiltration site was only partially excised. Postoperative chemotherapy was performed, and the progress was carefully followed up. Increased tumor markers were noted 12 months postoperatively, and abdominal CT revealed a 20-mm tumor in the abdominal wall. With a diagnosis of local recurrence, the abdominal wall tumor was excised. The tumor markers normalized postoperatively and chemotherapy was completed. The patient has survived without relapses for 30 months since excision.

Preoperative Prognostic Nutritional Index is a significant predictive factor for posthepatectomy bile leakage.

BACKGROUNDS/AIMS: It is known that preoperative nutritional status can influence patient outcomes after hepatectomy. Prognostic Nutritional Index (PNI) is a useful parameter to reflect patient outcomes undergoing gastro-intestinal surgery. The aim of this study was to retrospectively evaluate relationships of nutritional parameters, demographics, and surgical records with postoperative outcomes in a cohort study. METHODS: Curative hepatectomy was performed for 182 patients at the University of Miyazaki between 2015 and 2018. Each preoperative level of albumin, prealbumin, lymphocyte, total cholesterol, or the comprehensively calculated Onodera's PNI was examined as a nutritional parameter. RESULTS: The mean PNI was 39.6 ± 5.1, with PNI below 40 observed in 91 (50.0%) patients. Nutritional parameters were not different among patients with various liver diseases. Serum albumin or prealbumin level was significantly correlated with each hepatic parameter (p < 0.01). Prealbumin and total cholesterol levels were significantly correlated with postoperative prothrombin activity (p < 0.05). Albumin or prealbumin levels and PNI were significantly lower in patients with posthepatectomy complications, particularly bile leakage in comparison those without such complications (p < 0.05). Multiple logistic analysis showed that albumin level was an independent risk factor for complications after hepatectomy (risk ratio [RR]: 1.33) and that lymphocyte count was an independent risk factor for bile leakage (RR: 1.28) (p < 0.05). The cut-off level of albumin was approximately 3.8 mg/dL and that of lymphocyte count was 1,320/mm3. CONCLUSIONS: Preoperative PNI reflected perioperative liver functional status. It was a predictive parameter for postoperative complications, particularly biliary leakage.

Spontaneous common bile duct perforation due to choledocolithiasis accompanied with pancreaticobiliary maljunction in an adult: a case report.

BACKGROUND: Spontaneous common bile duct (CBD) perforation is an extremely rare disease in adults. We report an adult case of CBD perforation due to choledocolithiasis accompanied with pancreaticobiliary maljunction, which is, to our knowledge, the first such case report based on a search using PubMed. CASE PRESENTATION: A 71-year-old woman with consciousness disorder was transported to the emergency department of another hospital. She was diagnosed as having severe peritonitis with septic shock and transferred to our hospital for emergency surgery. Enhanced computed tomography (CT) revealed supraduodenal CBD dilation similar to a diverticulum and a defect of bile duct wall continuity. Furthermore, CT showed a long common channel of the pancreaticobiliary duct, so she was diagnosed as having spontaneous CBD perforation with pancreaticobiliary maljunction. Emergency surgery was performed that revealed a necrotic diverticulum-like change on the supraduodenal part, and a 2.5 × 1 cm perforation was found on the anterolateral wall of the CBD. Peritoneal lavage was performed, and CBD perforation was resolved with a T-tube. The patient suffered refractory intra-abdominal and retroperitoneal abscess formation and bleeding from the abdominal wall, which required a long period of postoperative management. The T-tube was removed on day 136, and the patient was transferred on day 153. CONCLUSION: The cause of CBD perforation is commonly considered to be increased intraductal pressure or weakness of the bile duct wall. In this case, pancreaticobiliary maljunction may have significantly influenced onset and the postoperative course. This case suggests that early surgical intervention and appropriate drainage are important to ensure survival.

Rare resected eight cases of duodenal adenocarcinomas.

INTRODUCTION: Duodenal adenocarcinoma is a rare malignancy; recently, it has been found to be accompanied by operative indications. METHODS: Nine consecutive rare cases were diagnosed with duodenal carcinoma (DC), in which clinicopathological characteristics were retrospectively examined. Age was ranged over middle-aged males and females. No clinical onset with severe symptoms was observed, and the specific treatment for accompanied diseases or habits was not found. OUTCOMES: One case of two T1 stage DCs that underwent pancreas-sparing duodenectomy. Stage II DC was diagnosed in three cases, and stage III DC was diagnosed in four cases. Pancreaticoduodenectomy (PD) mainly occurred in seven patients, and duodenectomy was limited in two patients. All operations were safely performed, and the postoperative course showed no severe morbidity. Histological findings showed R0 resection in eight cases and R1 at the retroperitoneal dissecting part in one case. Five patients with advanced-stage DC underwent adjuvant chemotherapy; however, four patients showed tumor recurrence within 12 months. With additional strong chemotherapy, eight patients survived up to 84 months, and one died of liver metastasis at 43 months after surgery. Three representative cases of mucosal invasion with widespread pancreas-sparing duodenectomy and advanced-stage DC cases undergoing duodenectomy or PD are shown. CONCLUSION: In the field of upper digestive tract surgery, duodenal adenocarcinoma and various applications of surgery or adjuvant chemotherapy for long-term survival are important.

Relationship between hepatic venous anatomy and hepatic venous blood loss during hepatectomy.

PURPOSE: Predicting increased blood loss based on anatomical intervascular relationships is essential in major hepatectomy. METHODS: We assessed 63 consecutive patients undergoing anatomical hepatectomy exposing the hepatic vein (HV) trunk at two institutes. Correlations between anatomical alterations of the hepatic inferior vena cava (IVC), HV, hepatic IVC, or right atrium (RA) and the blood loss per standard weight (BLSW) or blood transfusion (n = 18) were analyzed. The results of IVC partial clamping (PC) were additionally examined. RESULTS: The BLSW in type V-up anatomical morphology was significantly higher than that in straight type (p < 0.05). The parameters associated with an increased BLSW (> 13.5 mL/kg) were tumor size (> 4 cm), prothrombin activity (< 87%), CVP (> 7 mmHg), area of suprahepatic IVC (< 360 mm2), IVC-RA gap (> 28 mm), longitudinal angle of IVC (< 160°), and axial angle of the MHV (< 55°). A multivariate analysis revealed that a high IVC-RA gap was a significant independent risk factor (odds ratio; 4.32, p < 0.05). Among 25 patients undergoing IVC-PC, only three showed a remarkable decrease in hepatic venous bleeding. No other statistically significant differences in the surgical records were observed in most cases. CONCLUSION: The IVC-RA gap might be a promising novel predictive parameter reflecting increased blood loss leading to blood transfusion in anatomical hepatectomy.

The Influence of Dysphagia on Nutritional and Frailty Status among Community-Dwelling Older Adults.

Malnutrition is a core symptom of the frailty cycle in older adults. The purpose of this study was to investigate whether dysphagia influences nutrition or frailty status in community-dwelling older adults. The study participants were 320 Japanese community-dwelling older adults aged ≥65 years. All participants completed a questionnaire survey that included items on age, sex, family structure, self-rated health, nutritional and frailty status, and swallowing function. Nutritional status was categorized as malnourished, at risk of malnutrition, and well-nourished based on the Mini Nutrition Assessment-Short Form. The participants were then classified into a malnutrition (malnourished/at risk) or a well-nourished group (well-nourished). Frailty was assessed using the Cardiovascular Health Study criteria. The participants were then divided into a frailty (frail/pre-frail) or a non-frailty group (robust). Dysphagia was screened using the 10-item Eating Assessment Tool. Multiple logistic regression analysis was conducted to determine whether dysphagia was associated with nutritional or frailty status. The results revealed that dysphagia influenced both nutrition (odds ratio [OR]: 4.0; 95% confidence interval [CI]: 1.9-8.2) and frailty status (OR: 2.3; 95% CI: 1.0-5.2); therefore, the swallowing function would be an important factor for community-dwelling older adults on frailty prevention programs.

Protease-activated receptor-2 accelerates intestinal tumor formation through activation of nuclear factor-κB signaling and tumor angiogenesis in ApcMin/+ mice.

Hepatocyte growth factor activator inhibitor-1 (HAI-1), encoded by the SPINT1 gene, is a membrane-bound protease inhibitor expressed on the surface of epithelial cells. Hepatocyte growth factor activator inhibitor-1 regulates type II transmembrane serine proteases that activate protease-activated receptor-2 (PAR-2). We previously reported that deletion of Spint1 in ApcMin/+ mice resulted in accelerated formation of intestinal tumors, possibly through enhanced nuclear factor-κB signaling. In this study, we examined the role of PAR-2 in accelerating tumor formation in the ApcMin/+ model in the presence or absence of Spint1. We observed that knockout of the F2rl1 gene, encoding PAR-2, not only eliminated the enhanced formation of intestinal tumors caused by Spint1 deletion, but also reduced tumor formation in the presence of Spint1. Exacerbation of anemia and weight loss associated with HAI-1 deficiency was also normalized by compound deficiency of PAR-2. Mechanistically, signaling triggered by deregulated protease activities increased nuclear translocation of RelA/p65, vascular endothelial growth factor expression, and vascular density in ApcMin/+ -induced intestinal tumors. These results suggest that serine proteases promote intestinal carcinogenesis through activation of PAR-2, and that HAI-1 plays a critical tumor suppressor role as an inhibitor of matriptase, kallikreins, and other PAR-2 activating proteases.

[Conversion Surgery for Unresectable Advanced Gastric Cancer-A Case Report].

Unresectable advanced gastric cancer is associated with poor prognosis. In a few studies, long-term survival was achieved with conversion surgery in patients who responded to chemotherapy. Here, we have reported a case of unresectable advanced gastric cancer in which curative resection was achieved with conversion surgery. A 70-year-old man who was diagnosed with advanced gastric cancer with multiple liver metastases received S-1/cisplatin therapy(S-1 120 mg/kg of bodyweight[bw]plus cisplatin 90 mg/kg of bw)as primary therapy. Because of the adverse reactions, secondary treatment with irinotecan therapy(CPT-11 200 mg/kg of bw)was initiated, which led to clinical complete response. A local recurrence was observed 44 months later; hence, irinotecan therapy was reinitiated. Although the disease was stable for 30 months, disseminated nodules appeared; thus, immunotherapy(nivolumab 150 mg/kg of bw)was initiated as tertiary treatment for the progressive disease. Although the number of disseminated nodules decreased, frequent blood infusions were necessary for anemia. Distal gastrectomy was planned as palliative surgery. Since no noncurative factors were detected intraoperatively, we considered that curative resection could be achieved with pancreaticoduodenectomy and changed the procedure. The operative time was 6 hours 35 minutes, and there was a blood loss of 312 g. The pathological diagnosis was ypT2- N1M0P0M0, ypStage ⅡA. At 13 months postoperatively, the patient was alive without recurrence.

Two cases of bile duct carcinoma patients who underwent the photodynamic therapy using talaporfin sodium (Laserphyrin®).

The efficacy of adjuvant photodynamic therapy (PDT) using the new photosensitizer, talaporfin sodium (TPS) has been clinically examined in some patients with bile duct carcinoma (BDC). Based on our previous cohorts, a prospective clinical trial was attempted; however, only two cases were ultimately enrolled in 27 months. A 664-nm semiconductor laser (100 J/cm2) was applied through an endoscope to the tumor lesion within 6 h of an intravenous injection of 40 mg/m2 TPS according to the protocol for lung cancer. Case 1 was an 82-y.o. female patient with BDC at the left hepatic duct with biliary obstruction, percutaneous transhepatic biliary drainage (PTBD) was achieved, and the patient did not consent to surgery. She was followed up for 15 months to search for non-surgical treatments and eventually received PDT. Although mild photosensitivity occurred, she was discharged without severe adverse events. Biliary stenosis markedly extended and a PTBD tube was scheduled at 1 month. However, cancer immediately metastasized to the liver and she died 155 days after PDT. Case 2 was a 70-y.o. female with perihilar BDC and multiple biliary stenoses. Multiple biliary stenting was considered to be difficult. She received PDT and no adverse events were observed. Biliary stenoses markedly improved and multiple stenting was successfully performed. On day 132, she died of cancer progression. These two cases demonstrated the safety and efficacy of biliary malignant stenosis soon after PDT; however, long-term survival and a sufficient quality of life were not achieved. The combination of the PDT protocol and system chemotherapy or brachytherapy needs to be examined in clinical trials for advanced stage BDC.

Dysphagia is associated with oral, physical, cognitive and psychological frailty in Japanese community-dwelling elderly persons.

OBJECTIVE: To investigate which domains of frailty are associated with dysphagia in community-dwelling elderly persons. BACKGROUND: Dysphagia is a common cause of aspiration pneumonia in frail elderly persons in Japan. Although frailty is considered to be multidimensional, it is unclear which domains of frailty affect dysphagia. METHODS: The participants were 3475 independent Japanese elderly persons (≥65 years; 1555 men and 1920 women). A self-report questionnaire with a frailty checklist consisting of several domains (lifestyle, physical function, nutrition, oral function, homebound status, cognitive function and depressive mood) was used to determine the participants' characteristics. Dysphagia was defined as impaired swallowing in the oral function domain. To determine the associations between dysphagia and age, sex and the other domains on the frailty checklist, adjusted odds ratios (AORs) and 95% confidence intervals (95% CIs) were calculated using multiple logistic regression analysis. RESULTS: The multiple logistic regression analysis showed that dysphagia was independently associated with female sex (AOR = 1.35; 95% CI = 1.08-1.68), chewing ability (AOR = 1.70; 95% CI = 1.32-2.18), oral dryness (AOR = 1.94; 95% CI = 1.48-2.54), physical function (AOR = 2.19; 95% CI = 1.66-2.90), cognitive function (AOR = 1.68; 95% CI = 1.34-2.12) and depressive mood (AOR = 1.82; 95% CI = 1.41-2.35). CONCLUSION: Dysphagia was independently associated with oral, physical, cognitive and psychological frailty. These results suggest that frailty prevention strategy including swallowing training might be useful for community-dwelling independent elderly persons aged ≥65 years.

Usefulness of serum Mac-2 binding protein glycosylation isomer in patients undergoing hepatectomy: A case controlled study.

BACKGROUND: To evaluate the clinical significance of Mac-2 binding protein glycosylation isomer (M2BPGi), we investigated the relationship between M2BPGi and clinicopathological and surgical parameters and posthepatectomy complications. MATERIALS AND METHODS: We examined M2BPGi in 115 patients with hepatic malignancies undergoing hepatectomy. Significance as an independent prognostic marker was determined with multivariate logistic regression analysis. RESULTS: The mean serum M2BPGi level was 1.14 ±â€¯1.03 C.O.I. (range 0.2-5.79). M2BPGi in the chronic viral hepatitis group (1.42 ±â€¯1.25) was significantly higher than that in the other disease groups (p < 0.05). The M2BPGi level correlated negatively with platelet count, LHL15 and GSA-Rmax (r = -0.36, -0.69 and -0.56, respectively; p < 0.01) but correlated positively with serum hyaluronate level (fibrotic marker), ICGR15 and HH15 (r = 0.52, 0.63 and 0.57, respectively; p < 0.01). In 53 patients examined for histological hepatic fibrosis, the M2BPGi level was highest for hepatic fibrosis stage 4, indicating cirrhosis (2.15 ±â€¯1.56), and was significantly higher than that for stages 0-2 (p < 0.05). M2BPGi level did not correlate significantly with any surgical parameters. The preoperative level correlated significantly only with increased alanine aminotransferase level (r = -0.21, p < 0.05) and was significantly higher in patients with (1.35 ±â€¯0.78) than without (1.11 ±â€¯1.07) hepatectomy-related complications (p < 0.05). Area under the ROC curve analysis for prediction of hepatic fibrosis score 4 showed a cut-off value of 0.78 for M2BPGi to have high sensitivity (90%) and specificity (58%). For postoperative hepatectomy-related complications, only the M2BPGi level (at a cut-off value 0.90) tended to show significance (p = 0.06). CONCLUSIONS: The non-invasively measured serum level of M2BPGi reflected impaired liver function or cirrhosis and hepatectomy-related complications after surgery, making it potentially useful as a complementary parameter accompanying other liver function parameters.

Adult-onset primary Ewing's sarcoma of the right atrium: a case report.

BACKGROUND: Primary cardiac tumors, which are only detected in 0.001-0.03% of autopsies, are rare. Only 25% of primary cardiac tumors are malignant, of which 95% are sarcomas. Ewing's sarcoma, one of the Ewing's sarcoma of family tumors, is thought to be derived from neural crest cells. While Ewing's sarcoma usually presents in the bone of children, Ewing's sarcoma of cardiac origin is rare, with only a few reports described in the literature. The prognosis is unpredictable because of the scarcity and unestablished treatment. We herein report an extremely rare case of primary cardiac Ewing's sarcoma in the right atrium of a 64-year-old man. CASE PRESENTATION: The patient is a 64-year-old Japanese male who was referred to our hospital to treat a floating mass of the right atrium (RA). Although the patient was asymptomatic, we performed an operation to urgently resect the floating mass on the next day of admission due to the risk of pulmonary embolism. The operation was performed under cardiopulmonary bypass and cardiac arrest. We resected the tumor with at least 1.5 cm of the RA wall as a margin. The postoperative pathological diagnosis of the mass was compatible with a primitive neuroectodermal tumor (PNET, a form of Ewing's sarcoma). The cells were positive for CD56, CD99, and Vimentin and negative for S-100 and Desmin. Although no malignant cells were observed in the margin of the resected RA wall and the sarcoma was completely resected, he was transferred to another hospital to receive adjuvant postoperative chemotherapy to improve the prognosis by preventing subclinical micrometastasis. CONCLUSIONS: We experienced an extremely rare case of primary cardiac Ewing's sarcoma in the right atrium of a 64-year-old man, which was successfully resected under cardiac arrest. Although the sarcoma was completely resected, postoperative chemotherapy and long-term follow-up are recommended for patients with primary cardiac sarcoma because of the high rates of metastasis and recurrence.
