RESUMEN
Background: The World Health Organization (WHO) and the Food and Agriculture Organization (FAO) recommend the consumption of less than 2,000 mg of sodium/day to reduce blood pressure and the risk of conditions such as cardiovascular disease and coronary heart disease. The sodium intake among Vietnamese was reported to be 7,200 mg/d or more. Free L-glutamate enhances flavor when it is added to food and improves the taste of sodium-reduced foods. Objective: This study aims to investigate whether the intake of free L-glutamate-rich seasonings contributes to maintaining a low sodium intake in a cross-over study. Methods: From a total of 145 subjects, 42 participants were screened for participation in the cross-over design study. Subjects were randomly allocated to the Low free L-glutamate group (Low free L-Gl) and the Normal free L-glutamate group (Normal free L-Gl). Both received a direct educational guideline to reduce sodium intake. The Low free L-Gl group started with a restriction in the variety of free L-glutamate-rich seasonings, and the Normal free L-Gl group had no restriction in the variety of seasonings. Blood pressure was measured at week 0 (baseline), week 2, week 4, and week 6, while body weight, height, urine sodium and potassium excretion, chromogranin-A (CgA pmol/mg protein) from saliva, and free L-glutamate from food were measured at week 0, week 3, and week 6. Results: In Low free L-Gl, the amount of free L-glutamate in food decreased significantly from baseline to week 6 (p < 0.00), while it did not change in the Normal free L-Gl (p > 0.05). However, the reduction of sodium excretion at week 6 was 22% in Low free L-Gl (5,875 mg/d vs. 4,603 mg/d, p < 0.01) and 46% in Normal free L-Gl (6,107 mg/d vs. 3,277 mg/d, p < 0.00), both lower than the baseline. CgA (pmol/mg protein) did not show any difference between the two groups. Conclusion: The group with Normal free L-Gl intake showed a 46% reduction in sodium excretion by week 6 compared to the baseline. This suggests that the consumption of L-glutamate-rich seasonings when complemented with direct educational guidelines, can contribute to maintaining a low sodium intake.
RESUMEN
In-vacuum undulators (IVUs), which have become an essential tool in synchrotron radiation facilities, have two technical challenges toward further advancement: one is a strong attractive force between top and bottom magnetic arrays, and the other is a stringent requirement on magnetic materials to avoid demagnetization. The former imposes a complicated design on mechanical and vacuum structures, while the latter limits the possibility of using high-performance permanent magnets. To solve these issues, a number of technical developments have been made, such as force cancellation and modularization of magnetic arrays, and enhancement of resistance against demagnetization by means of a special magnetic circuit. The performance of a new IVU built upon these technologies has revealed their effectiveness for constructing high-performance IVUs in a cost-effective manner.
RESUMEN
A 63-year-old woman came to our hospital complaining of anemia and weight loss. The abdominal CT showed wall thickening from the upper to lower the body of stomach, and peritoneal dissemination. The EGD revealed a type 3 large tumor extending about 2/3 of the circumference. Adenocarcinoma was detected as a result of biopsy. The patient was diagnosed with unresected gastric cancer(cT4aN+M1, cStage â £). SOX plus nivolumab was selected as a first-line chemotherapy because of HER2 expression negative. Symptoms such as diarrhea developed, and the treatment was completed until 5 courses. Laparoscopic distal gastrectomy was performed after the disappearance of abdominal dissemination by CT scan and PET. Pathological examination revealed cancer cells were completely disappeared in the tumor, regional lymph nodes and white nodules in the peritoneum, and final diagnosis was ypT0N0M0, ypStage 0(histological effect determination is Grade 3). Six months after the operation, the patient has been free of recurrence.

Desmoid tumor is a rare tumor of the soft tissue. The frequency of occurrence is 2.4 to 4.3 cases per year per million people, which is a very rare disease. We experienced a huge intra-abdominal desmoid tumor which is thought to be the primary mesentery. The case was a male in his 20s. He visited a nearby doctor with a complaint of abdominal bloating and abdominal pain. Abdominal contrast CT revealed a huge abdominal mass with a clear boundary of 35×25 cm in size extending from the upper right abdomen to the pelvis. Surgery was performed with a diagnosis of an intra-abdominal mass. Open abdominal tumor resection. Due to infiltration into the duodenum, transverse colon, and pancreas, right hemicolectomy and duodenal combined resection were performed. The pathological diagnosis was a diagnosis of desmoid tumor.

A man in his 80s was referred to our hospital for further examination of partial pancreatic atrophy that was detected incidentally. Various imaging examinations including CT, MRI, and EUS did not reveal any obvious abnormal findings other than the partial pancreatic atrophy. However, cytological examination of serial pancreatic juice aspiration showed atypical cells. The presence of pancreatic intraepithelial carcinoma in the atrophy site was considered, and the patient underwent laparoscopic distal pancreatectomy. Pathological examination of the excised specimen confirmed the presence of high-grade pancreatic intraepithelial neoplasia consistent with the atrophy site, and the patient was diagnosed with pTisN0M0, Stage 0 pancreatic cancer. For the detection of early pancreatic cancer, it is important to be aware of partial pancreatic atrophy on imaging studies.

Phyllodes tumors are uncommon breast neoplasms that constitute 1-2% of breast malignancies. Invasive ductal carcinoma in the epithelial component of phyllodes tumor is very rare. When carcinoma is detected within the specimen, the management of treatment changes completely. We report a rare case of invasive ductal carcinoma arising in a giant borderline malignancy phyllodes tumor in a 51-year-old female patient. A painful 20 cm mass was found in her right breast, and a needle biopsy revealed fibroadenoma or benign phyllodes tumor, and a total mastectomy was performed. Pathological results showed that a borderline malignant phyllodes tumor coexisted with invasive ductal carcinoma. We explained that axillary surgery was necessary because invasive cancer was diagnosed after surgery, but the patient requested follow-up using images. Endocrine therapy was performed as postoperative adjuvant therapy, and the follow-up is underway without recurrence.

Purposeâ :â The aim of this study is to compare the nutritional status of older adult inpatients consuming Texture-Modified Diets (TMD) to older adult inpatients consuming a regular diet. Methodsâ :â The study was designed as cross-sectional and was conducted in three large hospitals in northern Vietnam. The data for 344 older adult inpatients were collected in 2021 by dietitians. Resultsâ :â The result showed 104 subjects were prescribed TMD. The textures of hospital diets have still not been adequately developed. In particular, the hospitals had not yet developed pureed meals. All older adult inpatients (74.7â ±â 6.8 years old, 52.9% female) had 28.8% malnutrition by the GLIM criteria. The TMD group had a malnutrition prevalence two times higher than the regular diet group. Total energy intake from hospital meal and outside snacks in the regular diet group was higher than in the TMD group, about 150 kcal. Although energy provided from the hospital diet in both groups was similar, hospital meal wastage in the TMD group was higher than in the regular diet group. Conclusionâ :â The older adult inpatients on TMD may have a nutritional status worse than those consuming a regular diet. Hospital diets need to be improved in texture and quality. J. Med. Invest. 69 : 230-236, August, 2022.

Type 2 diabetes mellitus (T2DM) has been increasing rapidly in Vietnam as well as world-wide. One of the major causes of the condition is low fiber intake. It is difficult to eat large amounts of vegetables every day to reach a sufficient amount of fiber but Textured Soybean Protein is rich in fiber. The study aimed to examine the effectiveness of Textured Soybean Protein consumption on T2DM patients. In this randomized controlled trial, 47 T2DM patients were divided into an intervention group (n=24) and a control group (n=23). The intervention group were asked to consume 40 g Textured Soybean Protein in 2 dishes for 4 wk. The control group continued their usual diet. Fasting blood samples were drawn before and after intervention to measure fasting plasma glucose (FPG), fructosamine, low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), total cholesterol (T-C), and triglycerides (TG). A 3-day food record was conducted at 1 wk before (baseline) and at the last week (final) of the intervention period. In the Textured Soybean Protein consumption group, there was a significant decrease in fructosamine (363±86 µmol/L to 347±82 µmol/L, p=0.03), T-C (5.2±0.9 mmol/L to 4.8±0.8 mmol/L, p=0.02) and TG (3.5±2.2 mmol/L to 2.8±2.0 mmol/L, p=0.02). Total energy intake in the two groups did not change significantly. There was a shift in the dietary pattern of the Textured Soybean Protein consumption group; lipid intake showed a significant decrease (p=0.001) and fiber intake increased by 6 g (p<0.001). The consumption of Textured Soybean Protein in the diet could have favorable effects in improving glycemic and lipid concentrations in T2DM patients.

A 74-year-old man with no chronic liver disease was admitted for an incidental liver tumor by computed tomography. Serological examinations for hepatitis B and C virus were negative and tumor markers, including carcinoembryonic antigen, α-fetoprotein, carbohydrate antigen 19-9, and des-gamma-carboxy prothrombin, were within the normal range. The contrast- enhanced magnetic resonance imaging revealed that the 26 mm in diameter patchy tumor occupied the S7 in the liver. The tumor boundary was enhanced slightly in the arterial phase and inside gradually in the portal phase, and the enhancement was faded in the late phase. As a characteristic finding, vessels penetrated the tumor. The tumor was diagnosed as cholangiocarcinoma, and the patient underwent right lateral sectionectomy. After 19 days postoperatively, the patient was discharged. The diagnosis of hepatic mucosa-associated lymphoid tissue(MALT)lymphoma was made by pathological examination. Currently, the patient has no recurrence for 5 months without adjuvant chemotherapy. The primary hepatic MALT lymphoma is a rare disease among primary hepatic malignant lymphomas. The patient must be followed up carefully because 2 cases were reported as recurrent cases after several years postoperatively although the disease has a good prognosis.

The patient is a 52-year-old woman who visited the general practitioner because of positive fecal occult blood test by medical examination. The patient underwent colonoscopy at the hospital, which revealed sigmoid colon cancer. Therefore, the patient was referred to our hospital for surgery. Preoperative CT scan revealed a well-defined and lobulated 54 mm tumor on the caudal side of the duodenal third portion. On MRI, the tumor showed low T1-weighted image signal and high T2-weighted and diffusion-weighted images signal, with low ADC. For preoperative diagnosis, we diagnosed sigmoid colon cancer and transverse colon mesenteric and performed laparoscopic sigmoid colon and transverse colon mesenteric tumor resections. The histopathological tumor diagnoses were sigmoid colon cancer(S, type 2, 30×30 mm, 1/2 circumference, moderately differentiated adenocarcinoma, pT3[SS], INF b, Ly1a, V1a, pN1b[#252: 2/4], sM0, fStage â ¢b)and transverse colon mesentery primary solitary fibrous tumor. The patient was treated with XELOX as the adjuvant chemotherapy and survived without recurrence until present.

A questionnaire survey was conducted by 17 doctors from 14 hospitals regarding treating elderly breast cancer in Yamaguchi Prefecture. The survey items are the implementation status of the geriatric assessment(GA)for the elderly, the state at the start of treatment(fit/vulnerable/frail), and the setting of restrictions on the indication of surgery and drug treatment (endocrine therapy/chemotherapy/molecular targeted therapy). Only one institution(6%)was used for GA; the tools used were the G8 and Charlson comorbidity index. Regarding surgical treatment, most facilities did not set restrictions according to age or condition. Endocrine and molecular-targeted therapies(anti-HER drugs)are highly tolerated, and most facilities do not have age restrictions. On the other hand, 40% of the respondents set age restrictions on chemotherapy. Four(24%) therapists said they would limit their age to 70 to 75 if the patient had a frail condition. These results tended to be similar to the reports of NCD-registered elderly breast cancer treatment.

A 69-year-old man was admitted for the severe anemia. Upper gastrointestinal endoscopy revealed type 3 gastric cancer (por1, HER2 negative)that spread from EG junction to the lesser curvature of lower gastric body. CT revealed LNs metastasis and the direct invasion to the diaphragm. We diagnosed the locally advanced gastric cancer(T4bN[+]M0, Stage â £A) and planed neoadjuvant chemotherapy. After 3 courses of S-1 plus CDDP therapy, serum CEA level increased. And the invasion to diaphragm was unclear although the tumor shrunk. After 3 courses of nab-PTX plus RAM therapy as the second- line, the tumor was PD. As the third-line chemotherapy, nivolumab therapy was repeated up to a total of 15 courses. As the tumor was PR, the patient underwent total gastrectomy with D2 lymphadenectomy. The histopathological examination revealed that the cancer invaded into the muscle layer without lymph nodes metastasis. The cancer was diagnosed as pT2 (MP)N0M0, Stage â B. The cancer cells were EB virus positive and MSI-high. CD 8 positive T lymphocytes infiltrated into the stroma. The patient is alive 26 months without adjuvant chemotherapy. The curative operation was able to perform because the infiltrative CD8 positive T lymphocytes reactivated with nivolumab responded remarkably.

BACKGROUND AND OBJECTIVES: The number of older adults is increasing rapidly in Vietnam. They suffer from various health problems, including malnutrition and dysphagia. By using a simple screening questionnaire such as the Mini Nutritional Assessment - Short Form (MNA-SF) and 10-item Eating Assessment Tool (EAT-10), nutritional and dysphagic status were screened in this study. The study aimed to determine the prevalence of and relationship between malnutrition and dysphagia in Vietnamese older adult inpatients. METHODS AND STUDY DESIGN: The study was designed as a cross-sectional study and conducted in three large hospitals in northern Vietnam. The data about nutritional status and dysphagia status of 1007 older inpatients were collected by dietitians. RESULTS: There were 71.6% of subjects at malnourished (MNA-SF score <8) and risk of malnutrition (MNA-SF score: 8-11). The prevalence of dysphagia by EAT-10 was 24.6%. The risk of dysphagia was independently associated with higher risk of malnutrition, with an odds ratio of 3.21 (95% CI: 1.93-5.31, p<0.001). In addition, malnutrition was also an independent predictor for risk of dysphagia, with an odds ratio of 3.09 (95% CI: 1.84- 5.17, p<0.001). CONCLUSIONS: Malnutrition and dysphagia prevalence were high; and malnutrition and dysphagia have a strong relationship among older adult inpatients in Vietnam. Therefore, nutritional and dysphagia screening at hospital admission are very important and recommended.

Hypertensive patients who adopt a sodium-restricted diet have difficulty maintaining this change, and this could increase stress. On the other hand, soup rich in umami substances (dashi) was reported to reduce indexes of anxiety and stress. The objective of this study was to measure mood and physiological stress indexes during administration of a sodium-restricted diet with and without an umami substance (free L-glutamate) by a cross-over randomized, single-blind, placebo-controlled trial in Japanese female university students. The baseline was measured for 5 days followed by a sodium-restricted diet intervention phase that lasted for 10 days. The Profile of Mood States questionnaire was administered, a stress marker in saliva (chromogranin-A) was measured, and the amount of sodium intake was confirmed from 24 h urine collection samples. Results showed that the sodium reduction was verified by 24 h urine excretion. The percentage of change in the stress marker from the baseline showed that the stress level in group without the umami substance was significantly higher than that in the group with the umami substance (p = 0.013) after receiving a sodium-reduced diet for 6 or more days, indicating that stress was alleviated. This study suggested that umami substances might help to ameliorate stress during a sodium-reduced diet, especially in the initial phase.
RESUMEN
Japanese salt consumption is high, about 10 g salt/d. Low salt intake reduces the risk of hypertension and cardiovascular disease. However, saltiness is an important taste in daily meals, greatly influencing eating habits. When hospital admission is short-term, reducing salt supply may have an adverse effect on food intake. The aim of this study is to find the effect of sudden change in dietary salt content on energy intake in elderly Japanese inpatients. The study is an observational study of 83 patients and was conducted in a hospital in Tokyo, Japan. The research period was three weeks, and included 8 g salt/d meals for the 1st week, 7 g salt/d meals for the 2nd week, and 7 g salt/d meals with total 1 g/d salt packs that patients were allowed to use freely for the 3rd week. The energy supply satisfied the individuals' energy requirements and was the same throughout the three weeks. Nutrition surveys and blood pressure measurements during the three weeks were conducted by dietitians and nurses, respectively. The results showed that energy intake of patients was reduced by about 90 kcal/d in the 2nd week compared with the 1st week and increased about 130 kcal/d in the 3rd week compared with the 2nd week. Blood pressure did not change during the research period. When high salt intake has become a habit, reducing salt supply suddenly in a short time period may lead to decreased energy intake in elderly inpatients but does not affect blood pressure.

An 85-year-old man presented to our hospital for loss of consciousness. Blood test revealed anemia, and the fecal occult blood test was positive. Colonoscopy revealed an ileal ulcer located 10-14 cm from the ileal end on the proximal side. Pathological examination was indicative of diffuse large B-cell lymphoma(DLBCL), and laparoscopic resection was selected as the technique of choice. The ileal tumor was strongly adhered to the sigmoid colon, and laparoscopic partial resection of the ileum and sigmoid colon was performed. In general, primary gastrointestinal lymphomas may occur, for which perforate and surgical resection is recommended. It is rare for malignant lymphomas to involve other intestinal areas, and laparoscopic surgery is useful in such cases.

Background: Indonesia suffers growing health problems such as obesity, diabetes, and other metabolic syndromes with dietary habit as one of risk factors. To control the lipid and glycaemic profile, high fibre intake has been recommended. This study administered 400g/day vegetable intake with its fiber contents and observed the effects in lipid profile and glycaemic control. Design: A parallel study of 30 pairs of menopausal women match paired in overweight, menopause, hyperlipidaemia, age, etc randomly divided into two groups (vegetable and control). The baseline data obtained from questionnaire and preliminary bloodwithdrawn of consented participants, then matched the characteristics included the results of lipid profile and glycated albumin. The administration was conducted for 21days by providing 400g/day of vegetable to the vegetable group subjects. Nutrition assessments were conducted at the baseline, middle, and final period. The data were analysed by using the unpaired and paired t-test. Results: Significant results (p<0.05) were seen in biochemical variables in the lipid profile of total cholesterol, LDL cholesterol, and HDL cholesterol and body weight and BMI within the vegetable group. Significant results for the same variables were shown between vegetable and control group at the final data (p<0.05). The nutrition assessments result showed significances (p<0.05) within vegetable group and between two groups on the final data. After 21 days, significant decreases were found on the intakes of energy, lipids, carbohydrates (p<0.05), while vegetable intake and fiber intake showed significant increases (p<0.05). Conclusion: These data suggest that maintaining a healthy diet of 400g/d vegetable can be effective in weight management and lipid profile control.
RESUMEN
The Vietnamese older adult population has increased rapidly on an annual basis and dysphagia has become a common issue. The nutritional status of older adults in general and of dysphagic older adults in particular has not received adequate attention. The automatic solution for cases of serious choking/aspiration is still a prescription for tube feeding. In developed countries, oral intake is a priority alternative for dysphagia and has positive consequences. This study aimed to investigate the nutritional status of and feeding practices for dysphagic older adult inpatients in some Vietnamese hospitals. The study was designed as a cross-sectional study and was conducted in three large hospitals in northern Vietnam. The data for 1007 older inpatients (58.3% were females, mean age was 75.5±7.3 y) about their dysphagic status, nutritional status and feeding practices were collected by dietitians. About 29% of the older adult inpatients suffered from malnutrition and 54% had a risk of malnutrition. Half of the dysphagia group had malnutrition and 42% were at risk of malnutrition. About 78% of the dysphagic older adults had oral intake of soft foods/regular foods and the remainder had tube feeding. Almost all dysphagic patients had reduced food intake over the prior 3 mo. The rate of pneumonia was quite high among dysphagic patients. The nutritional status of Vietnamese older adult inpatients in general and of dysphagic older adults specifically was poor. Oral intake of a texture-modified diet should be a method with priority over tube feeding or soft foods/regular foods for dysphagic patients.

BACKGROUND: This phase I study aimed to evaluate the safety, peptide-specific immune responses, and anti-tumor effects of a novel vaccination therapy comprising multi-HLA-binding heat shock protein (HSP) 70/glypican-3 (GPC3) peptides and a novel adjuvant combination of hLAG-3Ig and Poly-ICLC against metastatic gastrointestinal cancers. METHODS: HSP70/GPC3 peptides with high binding affinities for three HLA types (A*24:02, A*02:01, and A*02:06) were identified with our peptide prediction system. The peptides were intradermally administered with combined adjuvants on a weekly basis. This study was a phase I dose escalation clinical trial, which was carried out in a three patients' cohort; in total, 11 patients were enrolled for the recommended dose. RESULTS: Seventeen patients received this vaccination therapy without dose-limiting toxicity. All treatment-related adverse events were of grades 1 to 2. Peptide-specific CTL induction by HSP70 and GPC3 proteins was observed in 11 (64.7%) and 13 (76.5%) cases, respectively, regardless of the HLA type. Serum tumor marker levels were decreased in 10 cases (58.8%). Immunological analysis using PBMCs indicated that patients receiving dose level 3 presented with significantly reduced T cell immunoglobulin and mucin-domain containing-3 (TIM3)-expressing CD4 + T cells after one course of treatment. PD-1 or TIM3-expressing CD4 + T cells and T cell immunoreceptor with immunoglobulin and ITIM domains (TIGIT)-expressing CD8 + T cells in PBMCs before vaccination were negative predictive factors for survival. CONCLUSIONS: This novel peptide vaccination therapy was safe for patients with metastatic gastrointestinal cancers.
