Skeletal Muscle Quality Assessment in Patients With Cardiac Disease Associated With Type 2 Diabetes Mellitus: A Pilot Study.

Background Type 2 diabetes mellitus (T2DM) is associated with changes in skeletal muscle quantity and quality, such as increased ectopic fat. Cardiac rehabilitation (CR) aims to improve the exercise capacity and muscle strength. This study aimed to determine the relationship between qualitative changes in the skeletal muscles and exercise function in patients with and without diabetes mellitus. Methods The study included patients with cardiovascular diseases who entered CR. Of 72 CR patients (68.1±9.0 years) who underwent a cardiopulmonary exercise test and skeletal muscle assessment at discharge, 15 patients with T2DM and 15 without DM were selected using propensity score matching by age and gender. Results No significant differences in the skeletal muscle echo intensity (EI) (T2DM: 58.4, Non-DM: 53.4, p=0.32), skeletal muscle index (T2DM: 7.5 kg/m2, Non-DM: 7.2 kg/m2, p=0.36), or the weight-bearing index (WBI)(T2DM: 0.44, Non-DM: 0.50, p=0.35) existed between the two groups. The phase angle (PhA) (T2DM: 3.67°, Non-DM: 4.49°, p<0.05) and peak oxygen uptake (T2DM: 12.3 mL/kg/min, Non-DM: 14.8 mL/kg/min, p<0.05) were significantly lower in the T2DM group. PhA values showed a significant correlation with the WBI, a parameter of lower limb muscle strength (r=0.50, p<0.05). Conclusion The coexistence of cardiovascular disease and T2DM resulted in a decrease in the PhA, indicating a qualitative decrease in skeletal muscle mass. The PhA is also associated with lower limb muscle strength.

Perceptions of older adults and generativity among older citizens in Japan: a descriptive cross-sectional study.

BACKGROUND: As the population ages worldwide, including in Japan, there is a growing expectation for older adults to remain active participants in society. The act of sharing one's experiences and knowledge with younger generations through social engagement not only enriches the lives of older individuals, but also holds significant value for our society. In this study, we examined both positive and negative perceptions of older adults and investigated the correlation between these perceptions and generativity among older citizens. Additionally, we evaluated the impact of life satisfaction on these factors. METHODS: We conducted a survey of 100 older adults in Japan (mean age, 71.68 years) and utilized multiple regression analyses, using positive and negative perceptions of older adults, life satisfaction, and demographic factors as independent variables. The sub-categories of generativity-namely, generative action, concern, and accomplishment-were used as dependent variables. RESULTS: Participants who held a more positive perception of older adults demonstrated a higher level of generative actions and concerns. Additionally, participants who reported higher levels of life satisfaction also exhibited more generative actions, concerns, and accomplishments. Conversely, those who held a more negative perception of older adults were found to have higher levels of generative actions. CONCLUSION: Enhancing positive perceptions of older adults among them can boost the sub-categories of generativity. This study, which was conducted from an exploratory perspective, has several limitations, including a potential sampling bias. A more comprehensive examination of the relationship between perceptions of older adults and generativity is anticipated in future research.

Association between reasons for employment and burnout tendencies among rehabilitation technology professionals.

[Purpose] The deterioration in the psychological states of healthcare workers may impact the quality and quantity of medical care provided to patients, leading to unfavorable treatment outcomes. Thus, we aimed to investigate the relationship between reasons for employment and the mental health status of rehabilitation technology professionals in Japan. A cross-sectional survey was conducted using a questionnaire to gather relevant data. [Participants and Methods] Data from 112 rehabilitation technology professionals, including physical and occupational therapists as well as speech-language pathologists, were analyzed. Questionnaires were utilized to collect data on participant characteristics, reasons for employment, virtual competence, self-esteem, burnout levels, self-compassion responses, subjective health assessments, and feelings of isolation. [Results] Multiple regression analysis indicated that the regression coefficients of the Lubben Social Network Scale-6, the World Health Organization-five well-being index, the virtual ability scale, the self-esteem scale, and the reasons for employment scale scores were -0.168, -0.191, -0.273, -0.197, and -0.329, respectively. Additionally, structural equation modeling was used to verify the goodness-of-fit indices. The burnout scale scores exhibited a satisfactory fit with the Lubben Social Network Scale-6, the World Health Organization-five well-being index, the virtual ability scale, the self-esteem scale, and the reasons for employment, as indicated by all goodness-of-fit indices. [Conclusion] This study revealed a significant association between the reason for employment and burnout tendency, which was found to be the strongest. Therefore, it is important to know the reason for employment to ascertain burnout tendencies. Conversely, as associations were also found for several adjustment variables, it is necessary to consider not only the reasons for employment but also other factors when assessing burnout tendencies.

Long-Term Tailor-Made Exercise Intervention Reduces the Risk of Developing Cardiovascular Diseases and All-Cause Mortality in Patients with Diabetic Kidney Disease.

This study aimed to determine the effect of long-term exercise on the risk of developing cardiovascular diseases (CVD) and all-cause mortality in patients with diabetic kidney disease (DKD). A single-center, prospective intervention study using propensity score matching was performed over 24 months. The intervention group (n = 67) received six months of individual exercise instruction from a physical therapist, who performed aerobic and muscle-strengthening exercises under unsupervised conditions. New events were defined as the composite endpoint of stroke or CVD requiring hospitalization, initiation of hemodialysis or peritoneal dialysis, or all-cause mortality. The cumulative survival rate without new events at 24 months was significantly higher in the intervention group (0.881, p = 0.016) than in the control group (n = 67, 0.715). Two-way analysis of variance revealed a significant effect of the group factor on high density lipoprotein-cholesterol (HDL-C) which was higher in the intervention group than in the control group (p = 0.004); eGFRcr showed a significant effect of the time factor, which was lower at 24 months than before intervention (p = 0.043). No interactions were observed for all items. In conclusion, aerobic exercises combined with upper and lower limb muscle strengthening for six months reduce the risk of developing CVD and all-cause mortality in patients with DKD.

Neuromuscular Electrical Stimulation during Hemodialysis Suppresses Postprandial Hyperglycemia in Patients with End-Stage Diabetic Kidney Disease: A Crossover Controlled Trial.

Hemodialysis patients with diabetic kidney disease (DKD) experience blood glucose fluctuations owing to insulin removal. We evaluated the effects of single and long-term application of neuromuscular electrical stimulation (NMES) during hemodialysis on glycemic control. This trial was conducted in two stages: Stage 1, following a crossover design and 4 week washout period, eleven outpatients with DKD either underwent a single bout of NMES for 30 min (NMES period) or rested (control period) after receiving nutritional support during hemodialysis; Stage 2, following a crossover design and 4 week washout period, each participant received the intervention for 12 weeks. NMES was administered for 30 min at the maximum tolerable intensity. The mean subcutaneous glucose concentration and mean amplitude of glycemic excursion (MAGE) were determined by flash glucose monitoring for 24 h. Changes in glycoalbumin and MAGE before and after NMES initiation were evaluated. The mean blood glucose level and MAGE after a single bout of NMES were significantly lower than those after rest. Glycoalbumin levels and echo intensity of the rectus femoris tended to decrease, but not significantly by ANOVA due to a lack in statistical power after the dropout of three patients. NMES in end-stage DKD decreased blood glucose levels during and after hemodialysis.

The Japanese Society for Apheresis clinical practice guideline for therapeutic apheresis.

Most of the diseases for which apheresis therapy is indicated are intractable and rare, and each patient has a different background and treatment course prior to apheresis therapy initiation. Therefore, it is difficult to conduct large-scale randomized controlled trials to secure high-quality evidence. Under such circumstances, the American Society for Apheresis (ASFA) issued its guidelines in 2007, which were repeatedly revised until the latest edition in 2019. The ASFA guidelines are comprehensive. However, in the United States, a centrifugal separation method is mainly used for apheresis, whereas the mainstream procedure in Japan is the membrane separation method. The target diseases and their backgrounds are different from those in Japan. Due to these differences, the direct adoption of the ASFA guidelines in Japanese practice creates various problems. One of the features of apheresis in Japan is the development of treatment methods using hollow-fiber devices such as double filtration plasmapheresis (DFPP) and selective plasma exchange and adsorption-type devices such as polymyxin B-immobilized endotoxin adsorption columns. Specialists in emergency medicine, hematology, collagen diseases/rheumatology, respiratory medicine, cardiovascular medicine, gastroenterology, neurology, nephrology, and dermatology who are familiar with apheresis therapy gathered for this guideline, which covers 86 diseases. In addition, since apheresis therapy involves not only physicians but also clinical engineers, nurses, dieticians, and many other medical professionals, this guideline was prepared in the form of a worksheet so that it can be easily understood at the bedside. Moreover, to the clinical purposes, this guideline is designed to summarize apheresis therapy in Japan and to disseminate and further develop Japanese apheresis technology to the world. As diagnostic and therapeutic techniques are constantly advancing, the guidelines need to be revised every few years. In order to ensure the high quality of apheresis therapy in Japan, both the Japanese Society for Apheresis Registry and the guidelines will be inseparable.

A case of cardiac arrest due to a ruptured renal artery pseudoaneurysm, a complication of renal biopsy.

Renal artery pseudoaneurysms (RAPs) are a rare complication of percutaneous kidney biopsies that generally present as hematuria and back pain and are treated with angioembolization. A 60-year-old man was admitted to our emergency department for sudden left back pain. He was taking an oral anticoagulant for atrial fibrillation. He had undergone an ultrasound-guided percutaneous renal biopsy 26 days prior. We diagnosed him with hemorrhagic shock from the renal artery. Although he received a massive rapid blood transfusion, he went into cardiac arrest. Resuscitative endovascular balloon occlusion of the aorta (REBOA) was performed and, within 10 min, the patient achieved return of spontaneous circulation and regained consciousness. Subsequently, angioembolization was successfully performed for a 12.5 mm × 5.9 mm pseudoaneurysm in the left renal inferior pole close to the site of the renal biopsy. A total of 1680 mL of red blood cells and fresh frozen plasma were administered respectively until hemostasis was completed. He was then treated with continuous hemodialysis in the intensive care unit (ICU) for 6 days. He stayed in the ICU for 9 days and was moved to the general ward with full neurological recovery and a sufficiently stable condition to be able to walk. In conclusion, clinicians should be aware of the possibility of severe hemorrhagic shock due to RAPs after renal biopsy. Moreover, even if the patient goes into cardiac arrest, there is a possibility of full recovery if REBOA is performed and angioembolization is completed.

Severe Sepsis Caused by Bacteria That Entered via the Intestinal Tract: A Case of Crohn's Disease in a Child.

Typical causes of infection in Crohn's disease (CD) patients include intra-abdominal abscess, microperforation of the intestine, and fistula formation. Use of immunosuppressive drugs and abdominal surgery are often associated with CD sepsis. In this case, an 11-year-old boy who did not receive any concomitant treatment was admitted for evaluation owing to weight loss. On the 22nd day of hospitalization, he suddenly experienced a septic shock and was admitted to the intensive care unit (ICU). Enterobacter cloacae was detected in the blood culture. No findings as to the source of the intra-abdominal infection were present. The patient was treated with antibiotics, ventilator management, circulatory management with massive intravenous fluids and vasoactive agents, and blood purification therapy. Suspecting the presence of CD based on weight loss and a history of perianal abscess two years prior, a lower gastrointestinal endoscopy was performed. The results revealed a longitudinal ulcer with skip lesions. His general condition was stabilized, and he was extubated on the seventh day in the ICU. He subsequently began treatment for CD in the general pediatric ward. In conclusion, when a sepsis on account of the intra-abdominal infection is suspected, but the infection focus is not evident and the immunosuppressive background is unclear, CD should be considered. Doing so will ensure that sepsis and CD are treated appropriately.

The Effect of an Invasive Strategy for Treating Pancreatic Necrosis on Mortality: a Retrospective Multicenter Cohort Study.

BACKGROUND: Infected acute necrotic collections (ANC) and walled-off necrosis (WON) of the pancreas are associated with high mortality. The difference in mortality between open necrosectomy and minimally invasive therapies in these patients remains unclear. METHODS: This retrospective multicenter cohort study was conducted among 44 institutions in Japan from 2009 to 2013. Patients who had undergone invasive treatment for suspected infected ANC/WON were enrolled and classified into open necrosectomy and minimally invasive treatment (laparoscopic, percutaneous, and endoscopic) groups. The association of each treatment with mortality was evaluated and compared. RESULTS: Of 1159 patients with severe acute pancreatitis, 122 with suspected infected ANC or WON underwent the following treatments: open necrosectomy (33) and minimally invasive treatment (89), (laparoscopic three, percutaneous 49, endoscopic 37). Although the open necrosectomy group had a significantly higher mortality on univariate analysis (p = 0.047), multivariate analysis showed no significant associations between open necrosectomy or Charlson index and mortality (p = 0.29, p = 0.19, respectively). However, age (for each additional 10 years, p = 0.012, odds ratio [OR] 1.50, 95% confidence interval [CI] 1.09-2.06) and revised Atlanta criteria-severe (p = 0.001, OR 7.84, 95% CI 2.40-25.6) were significantly associated with mortality. CONCLUSIONS: In patients with acute pancreatitis and infected ANC/WON, age and revised Atlanta criteria-severe classification are significantly associated with mortality whereas open necrosectomy is not. The mortality risk for patients undergoing open necrosectomy and minimally invasive treatment does not differ significantly. Although minimally invasive surgery is generally preferred for patients with infected ANC/WON, open necrosectomy may be considered if clinically indicated.

Multicenter study of plasma diafiltration in patients with acute liver failure.

Plasma diafiltration (PDF) is a blood purification therapy in which simple plasma exchange (PE) is performed using a selective membrane plasma separator while the dialysate flows outside the hollow fibers. A prospective, multicenter study was undertaken to evaluate the changes in bilirubin, IL-18, and cystatin C, as well as the 28-day and 90-day survival rates, with the use of PDF according to the level of severity as measured by the Model for End-Stage Liver Disease (MELD) score. Twenty-one patients with liver failure were studied: 10 patients had fulminant hepatitis and PDF therapies were performed 28 times; 11 had acute liver failure with the therapy performed 96 times. Levels of total bilirubin, IL-18, and cystatin C decreased significantly after treatment. The 28-day survival rate was 70.0% and that at 90 days was 16.7%. According to the severity of the MELD score, each of the results compared well with the use of Molecular Adsorbent Recirculating System or Prometheus therapy. In conclusion, PDF appears to be one of the most useful blood purification therapies for use in cases of acute liver failure in terms of medical economics and the removal of water-soluble and albumin-bound toxins.

[Strategy for bacterial translocation in acute pancreatitis].

Although bacterial translocation (BT) is thought to be a main cause of secondary pancreatic infection, the clinical significance is still unclear. Therefore, we investigated relationship between pancreatic infection and BT, analyzing the results of treatments such as continuous regional arterial infusion of protease inhibitor and antibiotics (CRAI), selective digestive decontamination, and early enteral nutrition (SDD/EN) in 45 severe acute pancreatitis patients. The infection rate of 17 cases without CRAI, SDD/EN was 58.8%, and mortality was 23.5%. Antibiotics-resistant bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA) was often proven in infected pancreatic tissue. Whereas, in 16 cases who underwent both therapy, only one patient died of multi-organ failure (6.3%). Pseudomonas aeruginosa and K. pneumoniae were proven from his feces before pancreatic infection coincidence, and, in autopsy, these bacteria and MRSA were proved from necrotic pancreatic tissue. BT must be large cause of secondary pancreas infection, because CRAI and SDD/ EN prevent secondary pancreatic infection. But we must consider other infection routes, and development of antibiotics resistant bacteria.

Role of positron emission tomography with 2-deoxy-2-[18F]fluoro-D-glucose in evaluating the effects of arterial infusion chemotherapy and radiotherapy on pancreatic cancer.

BACKGROUND: This study evaluated the usefulness of positron emission tomography with 2-deoxy-2-[18F]fluoro-D-glucose (FDG-PET) in monitoring the response to continuous arterial infusion chemotherapy (CAI) combined with external radiation therapy (ERT) for unresectable pancreatic carcinomas. METHODS: Ten patients with unresectable pancreatic cancer were enrolled in this study. Computed tomography (CT) and FDG-PET were done before and after CAI (5-fluorouracil [FU], 500 mg/body per day) combined with ERT (50.4 Gy total dose). Tumor regression was evaluated by standardized uptake value (SUV) with FDG-PET, tumor size on CT, and changes in blood levels of carbohydrate antigen (CA) 19-9. The three methods of evaluation were compared. RESULTS: The ten patients were classified in three categories. In category I, tumor changes evident on CT and FDG-PET were consistent. In category II, CT could not accurately detect the area of the tumor. However, tumor uptake on FDG-PET decreased markedly after the treatment in category II patients. In category III, both CT and FDG-PET detected the tumor, as in category I. Although there was no definite change in tumor size on CT, FDG-PET uptake was markedly reduced immediately after the treatment. Reduction in tumor size did not appear on CT until 2 months later. CONCLUSIONS: FDG-PET aids in analysis of the effectiveness of chemotherapy and/or radiotherapy.

Positron emission tomography with 2-deoxy-2-[(18)F] fluoro- d-glucose for diagnosis of intraductal papillary mucinous tumor of the pancreas with parenchymal invasion.

We used positron emission tomography with 2-deoxy-2-[(18)F]fluoro- d-glucose (FDG-PET) in the diagnosis of two cases of malignant intraductal papillary mucinous tumor (IPMT) of the pancreas. A 56-year-old man and a 72-year-old man, both with tumors in the pancreatic head, were referred to Akita University Medical Center. Computed tomography revealed tumors with multiple cystic components in both patients. FDG-PET images showed markedly high FDG uptake in the area corresponding to a solid component found in one patient and diffuse faint uptake, higher than that of the surrounding tissue, in the other patient, who had no solid component. Histological examination of the resected specimens after pancreatectomy showed invasive carcinoma involving the pancreatic parenchyma in both patients. Although our experience is limited and preliminary, FDG-PET seems to be useful for the detection of malignancy in IPMT, especially in patients not showing any solid component on conventional diagnostic images such as computed tomography.

Plasma exchange for hypertriglyceridemic acute necrotizing pancreatitis: report of two cases.

We report two cases of hypertriglyceridemic necrotizing pancreatitis treated by plasma exchange (PE). The outcome of each case was quite different according to the timing of PE. A 36 year old man presented with abdominal pain, and a diagnosis of severe acute pancreatitis was made. His serum triglyceride (TG) level was 6,460 mg/dl. He did not undergo PE at first, however, his condition never improved and PE was performed 20 days after the onset of his illness. Finally, he died of multiple organ failure and sepsis. In contrast, a 52 year old man with acute necrotizing pancreatitis was referred to our department. He received PE quickly after hospital admission. His serum TG level, which was 3,540 mg/dl at hospital admission, dramatically returned to normal limits, and he was discharged from the hospital 62 days after admission. The prognosis of severe necrotizing pancreatitis due to hypertriglyceridemia is extremely poor. PE should be applied for the treatment of hypertriglyceridemic necrotizing pancreatitis immediately after its onset.

Management of pancreatic mass accompanying chronic pancreatitis.

We report two patients with focal, chronic pancreatitis that was diagnosed by dynamic computed tomography (CT) combined with intraoperative biopsy. In case 1, serum carbohydrate antigen (CA) 19-9 level rose to 160 U/ml. Abdominal ultrasonography, CT, and magnetic resonance imaging demonstrated a mass, of 4.5 cm in diameter, in the pancreatic head. On dynamic CT, the mass was enhanced similarly to the normal pancreatic parenchyma. In case 2, dynamic CT demonstrated a mass, of 3.0 cm in diameter, in the pancreatic head, which was enhanced similarly to the normal pancreatic parenchyma. From such characteristics of enhancement, both masses were suspected to be chronic pancreatitis rather than cancer, and the diagnosis was confirmed by intraoperative biopsy. Three years in case 1 and 2 years in case 2 have passed since their operations, and the size of each mass has not changed. With the use of dynamic CT combined with intraoperative biopsy, focal chronic pancreatitis could be diagnosed more accurately, and this may lead to a reduction in unnecessary pancreatic resection.

Acute emphysematous cholecystitis preceded by symptoms of ileus: report of a case.

We herein describe a case of acute emphysematous cholecystitis in which the patient presented with symptoms of ileus. The patient was a 72-year-old man with no history of diabetes mellitus. He presented with epigastric pain, vomiting, and low-grade fever. Plain abdominal radiography showed some intestinal gas and niveau, and he was admitted to our hospital with a diagnosis of ileus. The next day, the abdominal pain increased and was accompanied by muscular defense. Plain radiography and computed tomography of the abdomen were carried out, and an emergency laparotomy was performed under a diagnosis of panperitonitis due to a perforation of the gallbladder caused by acute emphysematous cholecystitis. The patient made favorable progress after the operation and was discharged on postoperative day 14. Percutaneous transhepatic gallbladder drainage has been increasingly performed for the treatment of acute emphysematous cholecystitis. but when a perforation of the gallbladder is suspected, a laparotomy first should be considered.
