RESUMO
PURPOSE: This study aimed to investigate the recent 10-year trends in cervical laminoplasty and 30-day postoperative complications. METHODS: This retrospective multi-institutional cohort study enrolled patients who underwent laminoplasty for cervical spondylotic myelopathy (CSM) or ossification of the posterior longitudinal ligament. The primary outcome was the occurrence of all-cause 30-day complications. Trends were investigated and compared in the early (2008-2012) and late (2013-2017) periods. RESULTS: Among 1095 patients (mean age, 66 years; 762 [70%] male), 542 and 553 patients were treated in the early and late periods, respectively. In the late period, patients were older at surgery (65 years vs. 68 years), there were more males (66% vs. 73%), and open-door laminoplasty (50% vs. 69%) was the preferred procedure, while %CSM (77% vs. 78%) and the perioperative JOA scores were similar to the early period. During the study period, the rate of preservation of the posterior muscle-ligament complex attached to the C2/C7-spinous process (C2, 89% vs. 93%; C7, 62% vs. 85%) increased and the number of laminoplasty levels (3.7 vs. 3.1) decreased. While the 30-day complication rate remained stable (3.9% vs. 3.4%), C5 palsy tended to decrease (2.4% vs. 0.9%, P = 0.059); superficial SSI increased significantly (0% vs. 1.3%, P = 0.015), while the decreased incidence of deep SSI did not reach statistical significance (0.6% vs. 0.2%). CONCLUSIONS: From 2008 to 2017, there were trends toward increasing age at surgery and surgeons' preference for refined open-door laminoplasty. The 30-day complication rate remained stable, but the C5 palsy rate halved.

In Japan, hyperuricemia is on the rise. The guideline for the management of hyperuricemia and gout recommends lifestyle changes before beginning drug therapy. This study aimed to evaluate the effectiveness of dietary counseling following the guideline. Thirty-three subjects (24 men and 9 women) with asymptomatic hyperuricemia underwent dietary counseling for 6 months based on the following recommendations : (1) prevent excessive purine intake, (2) prevent excessive fructose intake, (3) limit alcohol drinking, and (4) drink sufficient water. Obese subjects were counseled on adequate energy intake. Blood sampling, anthropometric measurements, dietary surveys, and 24-h urine collection were performed at baseline and at 6 months. Serum uric acid (S-UA) levels were significantly lower at 6 months compared to baseline. Water intake and urine volume were considerably higher at 6 months than at baseline. When compared to baseline, urine UA (U-UA) levels were significantly lower, and renal fractional excretion of UA (FEUA) was significantly higher at 6 months. Changes in renal function (serum creatinine, estimated glomerular filtration rate, and FEUA) were significantly associated with ?S-UA level. In this study, S-UA level was significantly decreased by dietary counseling in line with the guideline. This study illustrates the effectiveness of dietary counseling for asymptomatic hyperuricemia.

With the western influence in our diets, food consumption has changed, and our magnesium (Mg) intake is no longer optimal. Serum Mg (S-Mg) level is currently used as an indicator of Mg deficiency and is strictly regulated via compensatory mechanisms. It is believed that a 24-h urine collection can be used to evaluate potential Mg deficiency. This study aimed to assess whether Mg deficiency state as found in urine Mg (U-Mg) excretion and improving such deficiency with a diet that meets the Recommended Dietary Allowances (RDAs) of Mg for 15 d. Healthy Japanese women were recruited for Study 1 (n=22) and Study 2 (n=10). Study 1 was 1-d balance test, where fasting blood and 24-h urine samples were collected. Study 2 was 15-d diet load test, where fasting blood (days 1, 7, and 15) and 24-h urine (odd days) were collected. All test meals were made certain to have met the RDA for Mg for women in their 20s. In Studies 1 and 2, S-Mg was within the normal range. In Study 1, U-Mg excretion was 67.7±17.0 mg/d, with a large dispersion. In Study 2, U-Mg excretion on days 7 and 15 was significantly higher than on day 1, but have no significant differences in U-Mg excretion between days 7-15. U-Mg excretion can be a valuable indicator to evaluate Mg state. In young women, improvements in Mg deficient state were observed after 7-15 d of taking meals that met the RDAs of Mg.

During the treatment of hyperuricemia, attention should be paid to purine intake as part of the diet. Additionally, many patients with obese hyperuricemic expect early weight loss through glucose restriction. However, the amounts of purine in the diet are unknown. This study aimed to compare the purine content and potential renal acid load (PRAL) of a hospital diet and a low carbohydrate (LC). We calculated the nutritional values in the menus of the normal hospital (NH), energy-control (EC) diets served at several Shizuoka general hospitals, and the menus of LC diets. The amount of purine and PRAL was determined based on the nutritional values. The average daily purine content and energy were NH 349.0 mg, 1,808 kcal, EC 340.4 mg, 1,681 kcal, and LC 697.6 mg, 1,454 kcal, respectively. LC consumed more purine than the recommended daily intake of 400 mg. The PRAL score for NH was 4.5 mEq/d, EC 3.8 mEq/d, and LC 19.0 mEq/d, with LC representing diets with a higher acid load. In terms of both purine intake and uric acid excretion, the hospital diet is preferred over the low-carbohydrate diet for patients. Dietitians should exercise caution when recommending a low-carbohydrate diet for patients with hyperuricemia.

Fructose is associated with hyperuricemia and gout development. Focusing on fructose and fructose-containing disaccharides, we investigated the effects of three different types of carbohydrates (fructose, sucrose, and isomaltulose) on uric acid metabolism and gene expression profiling in peripheral white blood cells. In a randomized crossover study, ten healthy participants ingested test drinks of fructose, sucrose, and isomaltulose, each containing 25â g of fructose. Plasma glucose, serum and urine uric acid, and xanthine/hypoxanthine concentrations were measured. Microarray analysis in peripheral white blood cells and real-time reverse transcription polymerase chain reaction were examined at 0 and 120 in after the intake of test drinks. Serum uric acid concentrations for group fructose were significantly higher than group sucrose at 30-120â min and were significantly higher than those for group isomaltulose at 30-240â min. Several genes involved in the "nuclear factor-kappa B signaling pathway" were markedly changed in group fructose. No significant differences in the mRNA expression levels of tumor necrosis factor, nuclear factor-kappa B, interleukin-1ß, and interleukin-18 were noted. This study indicated that fructose intake (monosaccharide) elevated serum uric acid concentrations compared with disaccharide intake. Differences in the quality of carbohydrates might reduce the rapid increase of postprandial serum uric acid concentrations.
RESUMO
Age-related changes in muscle strength and physical functions, and the association between vitamin D status and skeletal muscle functions were investigated in 36 men (21-90 years old) and 52 women (21-104 years old). Significant ageing-related decreases in several skeletal muscle functions and serum 25-hydroxyvitamin D [25(OH)D] levels were observed in both men and women. Cut-off values for the Timed up and go (TUG) test, walking speed, handgrip strength and Barthel Index (BI) detecting walking difficulties in the receiver operating characteristic (ROC) analysis were 11.1 sec, 0.60 m / sec, 17.0 kg, and 90.0 in males, and 28.6 sec, 0.43 m / sec, 13.9 kg, and 67.5 in females, respectively. By comparing personal present data of muscle strength with these cut-off values, people can easily understand their process to walking difficulty. Therefore, these results are important and useful to avoid or to delay a handicapped and dependent status by improving the vitamin D level, rehabilitation and nursing care. J. Med.

INTRODUCTION/OBJECTIVES: Alcohol consumption is associated with hyperuricemia and gout. Previous studies have indicated a role for green tea catechins in uric acid (UA) metabolism. This study aimed to elucidate the acute effect of green tea catechins in terms of enhancing urinary excretion of UA and xanthine/hypoxanthine (Xa/HX; UA precursors) after alcohol ingestion. METHODS: In a randomized crossover study, ten healthy Japanese subjects consumed test meals, including a Japanese distilled spirit (Shochu) with water (SW) or Shochu with catechin-rich green tea (SC), each containing 20 g of alcohol. The SC contained 617 mg of catechin in total. Serum and urine UA and Xa/HX concentrations were measured. Blood samples were collected after 2.5 h, and urine samples were collected between 0 and 5 h after consuming the test meal. RESULTS: Urine UA and Xa/HX excretions were significantly higher in the SC group than in the SW group (UA: SW, 0.45 ± 0.08; SC, 0.52 ± 0.09; Xa/HX: SW, 0.08 ± 0.04; SC, 0.16 ± 0.05 mg/kg/h). UA clearance (CUA) and fractional UA excretion (FEUA) tended to increase more in the SC group than in the SW group (CUA: SW, 7.76 ± 2.14; SC, 8.75 ± 2.23 mL/min/1.73 m2; FEUA: SW, 6.08 ± 1.36; SC, 6.64 ± 1.42%). No significant differences in serum UA and Xa/HX concentrations were observed between two groups. CONCLUSIONS: It was concluded that green tea catechins can enhance the excretion of UA and Xa/HX, even though alcohol is ingested. TRIAL REGISTRATION NUMBER: UMIN000040076. Retrospectively registered 7 April 2020. https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000045687 Key Points ⢠Green tea catechins enhance the excretion of uric acid and xanthine/hypoxanthine, even when alcohol is ingested simultaneously. ⢠In case of non-adherence of limiting alcohol intake, catechin-rich green tea may be an effective dietary component to continue dietary therapy.

OBJECTIVES: There is substantial interest in using dark chocolate to prevent postprandial hyperglycemia. We investigated the effects of cacao polyphenol-rich chocolate on postprandial glycemic and insulinemic responses and whether cacao polyphenol-rich chocolate increases glucagon-like peptide-1 (GLP-1) secretion. METHODS: In a stratified, randomized, crossover study, 48 healthy participants ingested either water (W) or cacao polyphenol-rich chocolate plus water (C) 15 min before a 50 g oral glucose tolerance test (OGTT). Pre- and postprandial concentrations of blood glucose, insulin, free fatty acid, glucagon, and GLP-1 were evaluated. RESULTS: Peak plasma glucose concentrations did not differ significantly between groups W and C; however, plasma glucose concentrations at 120 min in group C were significantly lower than those in group W (P < .01). Postprandial serum insulin and plasma GLP-1 concentrations and incremental serum insulin and plasma GLP-1 area under the curve (AUC)-15-180 min for group C were significantly higher than those for group W (P < .05). When comparing the changes after the OGTT, the incremental plasma glucose AUC0-180 min for group C was significantly lower than that for group W (P < .05), but the incremental serum insulin and plasma GLP-1 AUC0-180 min did not differ significantly between groups W and C. CONCLUSIONS: This study indicated that the intake of cacao polyphenol-rich chocolate before a 50 g OGTT could enhance early insulin and GLP-1 secretion in healthy participants, and illustrates the potential of cacao polyphenol-rich chocolate in managing postprandial glucose excursions.

Higher serum phosphorus levels are associated with mortality and cardiovascular events, both in healthy individuals and those with chronic kidney disease. Owing to the increasing westernization of eating habits, a decrease in rice consumption and an increase in the intake of bread and noodle products were observed in Japan. This cross-sectional study investigated the influence of staple food (rice, bread, and noodle) consumption patterns on the serum levels of phosphorus and phosphate-regulating factors in 103 healthy young participants. Fasting blood and 24-h urine samples were collected; data about dietary habits were collected using a brief-type self-administered diet history questionnaire. Cluster analysis was conducted to assess subgroups classified according to staple food consumption patterns. Serum levels of phosphorus and phosphate-regulating factors did not significantly differ between subgroups classified based on the frequency of rice or bread consumption. However, the serum levels of phosphorus and fibroblast growth factor 23 were more significantly elevated in the higher than in the lower noodle consumption frequency subgroup. Cluster analysis defined three clusters, and the serum phosphorus levels in the high-noodle cluster were significantly higher than that in the high-bread and high-rice clusters. A high consumption of noodles was associated with elevated serum phosphorus levels. The trial was registered in the University Hospital Medical Information Network (UMIN) Center system (The name of the trial register: Hidekazu Arai, and UMIN accession number: UMIN000034352).
RESUMO
A clearer understanding of skeletal muscle mass (SMM) in middle-aged and elderly individuals is important for maintaining functionality. In the present study, age-related changes in SMM, the threshold of SMM with walking difficulty, intestinal nutrient absorption rate, and various serum factors were examined in Japanese populations of different ages. We used 24-h creatinine excretion as a measure of total body SMM. Age-related decreases in SMM, intestinal nutrient absorption rates, and serum 25-hydroxyvitamin D [25(OH)D] concentrations were significantly higher in women than in men. The cut-off values for SMM (kg), its percentage of total body weight (BW), the SMM index [SMMI] (Kgâ /â m2), and creatinine height index (CHI) (%) in elderly individuals with walking difficulty were approximately 8-10 kg, 17-20% of BW, 3.9-4.6 kgâ /â m2, and 44%, respectively. Serum 25(OH)D concentrations were closely associated with SMM (kg, % of BW, kgâ /â m2) and CHI (%) as well as the intestinal absorption rates of nitrogen (%) and phosphorus (%) in women, but not in men. The present results demonstrate that vitamin D is an important metabolic factor in skeletal muscle, and contributes to the optimal management of skeletal muscle and the prevention of sarcopenia. J.

OBJECTIVE: The ratio of dietary carbohydrate to fat may affect phosphorus metabolism because both calcium and phosphorus are regulated by similar metabolic mechanisms, and a high-fat diet (HFD) induces deleterious effects on the absorption of dietary calcium. We hypothesized that an HFD induces an increase in phosphorus absorption. The aim of this study was to evaluate the effects of differences in the quantity and quality of dietary fat on phosphorus metabolism over the short- and long-term. METHODS: Eighteen 8-wk-old Sprague-Dawley male rats were fed an isocaloric diet containing varied ratios of carbohydrates to fat energy and sources of fat (control diet, HFD, and high- saturated fat diet [HF-SFA]). At 3 d and 7 wk after the allocation and initiation of the test diets, feces and urine were collected and used for phosphorus and calcium measurement. RESULTS: The fecal phosphorous concentration (F-Pi) was lower in the HF-SFA group than in the other two groups; however, the urine phosphorus concentration (U-Pi) was significantly higher in the HF-SFA group than the other two groups when the rats were fed over the short- (P < 0.01) and long -term (P < 0.01 versus control, P < 0.05 versus HFD group). There were no significant differences in type-IIa sodium-phosphate cotransporter (NaPi-2 a) and type-IIc sodium-phosphate cotransporter (NaPi-2 c) mRNA expression, which are renal phosphate transport-related genes; however, the expression of type-IIb sodium-phosphate cotransporter (NaPi-2 b) and type-III sodium-phosphate cotransporter (Pit-1) mRNA in the duodenum was higher in the HFD and HF-SFA groups than in the control group (P < 0.05), although there were no significant differences in these in the jejunum. CONCLUSIONS: The present results indicated that an HFD, particularly HF-SFA, increases intestinal phosphate absorption compared with control.

BACKGROUND: This retrospective, historically controlled investigative study examined the benefit of a nutritional support pathway that included nutritional education before the start of conditioning and emphasized oral nutrition in response to nutrition-related adverse events in patients undergoing hematopoietic stem cell transplantation (HSCT). MATERIAL AND METHODS: Participants were patients undergoing allogeneic HSCT; 46 were in the control group (i.e., did not follow our nutritional pathway) and 36 were in the group that underwent nutritional intervention (enhanced nutrition group). We compared the following parameters between groups from the day before the start of conditioning to the day after completion of parenteral nutrition (PN): percent loss of body weight (%LBW), percent loss of skeletal muscle mass (%LSMM), and estimated basal energy expenditure (EBEE) sufficiency rate. The relationship between each parameter and %LBW was also examined. We also compared nutritional indices, gastrointestinal graft versus host disease (GvHD) grade, oral energy intake, and %LBW between groups. RESULTS: There was a relationship between %LBW, %LSMM, and EBEE sufficiency rate in both groups. Compared with the control group, the enhanced nutrition group had significantly improved energy intake amount, EBEE sufficiency rate, PN duration, and oral energy intake over time. The enhanced nutrition group also had increased oral energy intake, no difference in gastrointestinal GvHD grade, and improved %LBW compared with the control group. CONCLUSIONS: Use of our nutritional support pathway in patients undergoing HSCT may be beneficial for %LBW and gastrointestinal GvHD grade, enabling early enhanced nutritional intervention after HSCT.

RESUMO
Hyperphosphatemia is associated with an increased risk of developing cardiovascular disease. Recently, it has been shown that high serum phosphorus levels are associated with increased cardiovascular events in healthy subjects, but the dietary factors determining serum phosphorus level have not been fully investigated. The study investigated the influence of habitual dietary factors on serum phosphorus levels in healthy young participants. This cross-sectional study conducted fasting blood sampling in 109 healthy young people and used a brief-type self-administered diet history questionnaire to evaluate the subject's habitual meals. Since the bioavailability of dietary phosphorus depends on the food sources, habitual phosphorus intakes from different food groups and intake frequency (times/month) of processed foods were calculated. The mean serum phosphorus level was 3.9 0.5 mg/dl ; 10.1% of the subjects had serum phosphorus levels that exceeded the reference levels of 4.5 mg/dl. Total phosphorus intake and phosphorus intake from animal-based food did not differ between serum phosphorus quartiles. Higher intake of confectionery was associated with increased serum phosphorus levels. This study showed that frequent consumption of confectionery was associated with elevated serum phosphorus levels. Additional studies are needed to determine whether this is a causal relationship. J. Med. Invest. 66 : 134-140, February, 2019.

The objective of this study was to investigate whether sodium-glucose cotransporter 2 inhibitors (SGLT2i) treatment in patients with type 2 diabetes induced compensatory hyperphagia by reducing fibroblast growth factor 21 (FGF21) secretion. This prospective study was performed in 26 type 2 diabetes patients treated with dapagliflozin (5 mg/day). Hormonal factors associated with glucose metabolism, dietary intakes estimated by brief self-administered diet-history questionnaire (BDHQ), body weight (BW), and body composition were measured at baseline, and 4 and 12 weeks after dapagliflozin. At 12 weeks, HbA1c levels and BW decreased significantly (both p < 0.0001). BMI at baseline was predictive to baseline log10 (FGF21) (p = 0.037). This study showed no change in FGF21, but insulin and glucagon levels decreased significantly (both p < 0.05). Although hyperphagia was found in 10 patients (38.5%), defining hyperphagia as >20% increase in carbohydrate intake, dapagliflozin treatment induced no hyperphagia, when analyzed by all subjects, and there was no significant association between changes in FGF21 levels and carbohydrate intake. On the other hand, a positive correlation between changes in FGF21 levels or carbohydrate intake and BW was observed (both p < 0.005). Taken together, this study demonstrates that the intervention to maintain the reduced levels in FGF21 is beneficial for BW reduction in type 2 diabetes patients treated with SGLT2i.

AIM: This study aimed to evaluate the effect of diet on serum lipids and to assess the effectiveness of long-term dietary therapy for hypertriglyceridemia. METHODS: Seventy-nine patients (34 males and 45 females) with hypertriglyceridemia were enrolled and underwent dietary counseling for 12 months based on the following three recommendations: (1) reduce carbohydrate intake, (2) increase n-3 polyunsaturated fatty acid (PUFA) intake, and (3) limit alcohol drinking. We examined the effect of dietary therapy for 6 months on serum triglyceride (TG) levels and also compared the effectiveness of dietary and combined drug therapies on preventing arteriosclerotic disease from 7 to 12 months. RESULTS: We observed that serum TG levels of the patients receiving dietary counseling were decreased compared with baseline at 6 months. Body weight and serum TG levels were decreased, and serum high-density lipoprotein levels were increased in the dietary therapy alone group, whereas BW, body mass index, and abdominal circumference were decreased in the combined drug treatment group compared with baselines at 6 and 12 months. Furthermore, the dietary therapy alone group demonstrated reductions in intake of total energy, carbohydrate, and saturated fatty acids, as well as n-6/n-3 PUFA ratio compared with baselines, but only n-6/n-3 PUFA ratio was decreased in the combined drug treatment group. CONCLUSION: This study demonstrated a decrease in serum TG level after 12 months of dietary therapy similar to drug therapy, which suggests that it is an effective treatment for hypertriglyceridemia, and heightened awareness should be made to encourage its use.The clinical trial registration number: UMIN000028860.

In this study, we examined the fasted and postprandial triacylglycerol (TG) levels in KK- A y mice fed a high-fat diet (HFD) or a HFD containing either 500 ppm (0.05%) of diosgenin or 500 ppm (0.05%) of diosgenin-containing Chinese yam sanyaku. Oral fat tolerance tests revealed that, not only in the fasting state but also after loading of lipid emulsion, plasma levels of TG were significantly reduced in sanyaku- and diosgenin- fed mice. Levels of fat oxidation, especially in the dark phase (from 7 p.m. to 7 a.m.), were increased in the sanyaku and diosgenin groups. Moreover mRNA levels of lipoprotein lipase and peroxisome proliferator-activated receptor γ, coactivator 1α were moderately upregulated in the liver of sanyaku- and diosgenin-ingested mice. These results suggest that consecutive ingestion of diosgenin or diosgenin-containing sanyaku at the dose achievable in a human diet potentially ameliorates fasted and postprandial hypertriacylglycerolemia, which could be associated with the improvement of TG metabolism.

The objective was to evaluate the effect of replacing milk with soymilk or calcium-fortified soymilk as a part of a meal on postprandial serum phosphorus levels. This study had a randomized crossover design. Ten healthy subjects were enrolled and consumed three test meals that contained either milk, soymilk, or calcium-fortified soymilk containing the same amount of calcium as milk. Blood samples were collected at 0, 30, 60, 120, 240 and 360 min and urine samples were collected from 0 to 360 min after consuming the test meal. Serum phosphorus levels decreased the most after the ingestion of the soymilk meal, and the least after the ingestion of the milk meal. After the ingestion of each meal, serum intact parathyroid hormone levels showed an initial drop followed by a gradual rise, and these changes were more pronounced for the soymilk meal than for the milk meal and the soymilk + calcium meal. Our study shows that replacing milk with soymilk as a part of a meal may suppress the postprandial elevation in serum phosphorus levels, even when the soymilk contains the same amount of calcium as milk.
RESUMO
By using 24 hour urinary creatinine levels, skeletal muscle mass (kg), its rate (%) of body weight and creatinine height index (%) were determined in old Japanese women suffering from walking difficulty in nursing home and compare with those of young university students. Those of old subjects showed approximately 30-50%, 36-44% and 44-46% of young subjects, respectively. It is suggested that these values are important and useful biomarkers for the planning and the achievement of rehabilitation program for the maintaining and restoring skeletal muscle mass and for the careful support by registered care workers to aged persons.
