The purpose of this study was to evaluate the physical features of pediatric patients with lumbar spondylolysis (LS), factors that increase the load during compensatory movements at the lumbar spine, and the outcomes of rehabilitation. Twenty patients were included. Fifteen items were used:fingertip‐to‐floor distance (FFD), straight leg raising (SLR), heel‐to‐buttock distance (HBD), tightness of the rectus femoris, the lateral and medial rotator muscles, iliopsoas, tensor fascia lata, adductor muscles, soleus muscle, and latissimus dorsi, and trunk rotation, sit‐ups and endurance of the abdominal and back muscles. Initial findings were judged as positive or negative using previously reported cut‐off values and were re‐evaluated 2 or 3 months later. Positive tests were found for HBD and tightness of the rectus femoris in 85% of the patients, for endurance of the abdominal muscles in 75%, SLR and sit‐ups in 70%, and FFD and tightness of the external rotator muscles in 60%. The physical features varied according to the type of sport played, and some patients were refractory to rehabilitation. Only 17.6%, 33.3%, and 40.0% of patients with initially positive findings for HBD, tightness of the external rotator muscles, and endurance of the abdominal muscles, respectively, achieved improvements after rehabilitation.

Effects of pre-germinated brown rice (PGBR) on postprandial blood glucose and insulin concentrations were compared with brown rice (BR) and white rice (WR) in two studies. In the first study, we investigated the time course of postprandial blood glucose and insulin concentrations after ingesting 25% (W/V) glucose solution, PGBR, BR or WR in 19 healthy young subjects. In the second study, dose-dependent effect of PGBR on the time course of postprandial blood glucose concentrations was compared among 4 different mixtures of PGBR and WR in 13 healthy young subjects. They were solely PGBR, 2/3 PGBR (PGBR: WR=2: 1), 1/3 PGBR (PGBR: WR=1: 2) and solely WR. Each sample was studied on a different day. The samples were selected randomly by the subjects. All the rice samples contained 50g of available carbohydrates. The previous day the subjects ate the assigned dinner by 9:00 pm and then were allowed only water until the examination. The next morning, they ingested each test rice sample with 150ml of water in 5-10 min. Blood was collected into capillary tubes from finger at 0, 30, 60, 90 and 120 min after the ingestion. The incremental areas under the curve (IAUC) of blood glucose concentrations (IAUC-Glc) for 120 min after the administration of PGBR and BR were lower than those after WR. In contrast the IAUC-Glc of BR and PGBR were not different (Study 1). The higher the ratio of PGBR/WR, the lower the glycemic index became (Study 2). These results suggest that intake of PGBR instead of WR is effective for the control of postprandial blood glucose concentration without increasing the insulin secretion. J. Med.

This study examined the effects of hand massage on autonomic activity, anxiety, relaxation and sense of affinity by performing it to healthy people before applying the technic in actual clinical practice. Findings were showed below: 1) the significant increase in the pNN50 and the significant decrease in the heart rate meant the intervention of massage increased the autonomic nervous activity, improved the parasympathetic nerve activity and reduced the sympathetic nerve activity. This means the subjects were considered to be in a state of relaxation. 2) Salivary α amylase has been reported as a possible indicator for sympathetic nerve activity. In this study, there was no significant difference in the salivary α amylase despite a decrease after massage. 3) State anxiety score is temporal situational reactions while being in the state of anxiety and this score decreased significantly after massage. 4) The level of willingness to communicate with other person and the sense of affinity toward the massage-performer had a positive change of 70 percent. From this, it can be considered that a comfortable physical contact between a patient and a nursing profession, who are in a supported-supportive relationship, leads to an effect of shortening the gap in their psychological distance.

Reducing dietary calorie density (CD) is useful in body weight management. This study investigates the association between dietary habits and preferences for different CDs. We conducted a randomized crossover study of 232 healthy subjects who consumed packed lunch boxes containing a control, high-meat and low-rice, low-vegetable, medium-fat and low-vegetable, high-fat, and high-fat and low-vegetable meals over six sessions. The subjective levels of sensory properties were assessed over time using a visual analog scale and the area under the curve. Subjects were assessed for dietary habits using a brief-type self-administered diet history questionnaire (BDHQ) and were divided into two groups based on a daily fat energy ratio ≥ 25% (high fat [HF], n=116) and < 25% (normal, n=116) that was matched for age, body mass index, and sex ratio. Our findings indicate that the desire for sweetness was higher in the HF group than in the normal group, regardless of the meals consumed. Particularly, among the 500-kcal low-CD meals, a high-protein meal provided greater fullness and satisfaction and lower prospective consumption in the HF group than in the normal group. Therefore, our study demonstrates that postprandial appetite sensation is associated with dietary habits of fat intake. J. Med. Invest. 63: 241-247, August, 2016

Stress is a pervasive factor in everyday life that critically affects development and functioning. Severe and prolonged stress exposure impairs homeostatic mechanisms, particularly associated with the onset of depressive illness. Brain food is aimed at preventing as well as treating a growing number of stress-related mental disorders. Some topics on the association of stress and nutrition is reviewed. (1) An increased activity of serotonergic neurons in the brain is an established consequence of stress. An increase in brain tryptophan levels on the order of that produced by eating a carbohydrate-rich/protein-poor meal causes parallel increases in the amounts of serotonin released into synapses. (2) Eating is thought to be suppressed during stress, due to anorectic effects of corticotrophin releasing hormone, and increased during recovery from stress, due to appetite stimulating effects of residual cortisol. (3) A strong inverse association between coffee intake and risk of suicide. (4) Night eating syndrome has been found to occur during periods of stress and is associated with poor results at attempts to lose weight and disturbances in the hypothalamic-pituitary-adrenal axis. (5) Dietary antioxidants present in fruits and vegetables may improve cognitive function. Therefore, it is concluded that the establishment of functional foods that correctly regulate stress response must be firmly based upon scientific knowledge and legal regulation.

Introduction:Branch atheromatous disease (BAD) is a type of cerebral infarction caused by stenosis or occlusion at the entrance of the penetrating branch due to the presence of plaque. Despite its clinical significance, it is not clear how these plaques are formed. Focal geometrical characteristics are expected to be as important as vascular risk factors in the development of atherosclerosis. This study aimed to analyze the association between middle cerebral artery (MCA) geometric features and the onset of BAD. Shear stress results from the blood flow exerting force on the inner wall of the vessels and places with low wall shear stress may be prone to atherosclerosis. At the curvature of blood vessels, the shear stress is weak on the inside of the curve and plaque is likely to form. When this is applied to the MCA M1 segment, downward type M1 is likely to form plaques on the superior side. Because the lenticulostriate artery usually branches off from the superior side of the MCA M1 segment, in downward type M1, a plaque is likely to be formed at the entrance of the penetrating branch, and for that reason, BAD is likely to onset. Methods:We retrospectively reviewed hospitalized stroke patients with BAD and investigated the morphology of their MCA using magnetic resonance imaging. The M1 segment was classified as straight or curved. Additionally, we compared the difference between the symptomatic and the asymptomatic side. Data regarding patients’ medical history were also collected. Results:A total of 56 patients with lenticulostriate artery infarctions and BAD were analyzed. On the symptomatic side, downward type M1 accounted for the largest proportion at 44%, whereas on the asymptomatic side, it was the lowest, at 16%. Conclusion:A downward type MCA may be associated with the onset of BAD and the morphological characteristics might affect the site of plaque formation. J. Med. Invest. 70 : 411-414, August, 2023

X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder associated with peroxisomal dysfunction. Patients with this rare disease accumulate very long-chain fatty acids (VLCFAs) in their bodies because of impairment of peroxisomal VLCFA ?-oxidation. Several clinical types of X-ALD, ranging from mild (axonopathy in the spinal cord) to severe (cerebral demyelination), are known. However, the molecular basis for this phenotypic variability remains largely unknown. In this study, we determined plasma ceramide (CER) profile using liquid chromatography-tandem mass spectrometry. We characterized the molecular species profile of CER in the plasma of patients with mild (adrenomyeloneuropathy;AMN) and severe (cerebral) X-ALD. Eleven X-ALD patients (five cerebral, five AMN, and one carrier) and 10 healthy volunteers participated in this study. Elevation of C26:0 CER was found to be a common feature regardless of the clinical types. The level of C26:1 CER was significantly higher in AMN but not in cerebral type, than that in healthy controls. The C26:1 CER level in the cerebral type was significantly lower than that in the AMN type. These results suggest that a high level of C26:0 CER, along with a control level of C26:1 CER, is a characteristic feature of the cerebral type X-ALD. J. Med. Invest. 70 : 403-410, August, 2023

Background : Non-alcoholic steatohepatitis (NASH) is associated with a higher risk of hepatocellular carcinoma (HCC), and the importance of the gut?liver axis has been recognized in NASH-associated HCC. We investigated the effect of TU-100 on the intestinal microbiome and hepatocarcinogenesis in a NASH model. Methods : Seven-week-old Tsumura Suzuki obese diabetes mice, a model that shows the spontaneous onset of NASH and HCC, were used. They were divided into a TU-100 treated group and a control group. Mice were sacrificed at 24 and 48 weeks to evaluate hepatic steatosis, fibrosis, carcinogenesis, cytokine expression, and microbiome abundance. Results : At 24 weeks, the TU-100 group showed significantly lower expression of IL6, IL1B, and ACTA2 mRNA in the liver (P?<?0.05). At 48 weeks, the TU-100 group showed significantly lower levels of serum alanine aminotransferase. The TU-100 group also showed a lower rate of NASH than the control group (28% vs 72%?;?P?=?0.1). Tumor diameter was significantly smaller in the TU-100 group compared with that in the control group (P?<?0.05). Regarding the intestinal microbiome, the genera Blautia and Ruminococcus were increased in the TU-100 group (P?<?0.05), whereas Dorea and Erysipelotrichaceae were decreased in the TU-100 group (P?<?0.05). Conclusions : TU-100 regulates the intestinal microbiome and may suppress subsequent hepatocarcinogenesis in the NASH model. J. Med. Invest. 70 : 66-73, February, 2023

This is a case of a woman who was diagnosed with resistance to thyroid hormone after total thyroidectomy for thyroid cancer. Preoperative laboratory examination revealed the syndrome of inappropriate secretion of TSH, however, the patient had no thyrotoxic symptoms and no family history. Based on the results of ultrasonography and fine needle aspiration, she was diagnosed with papillary thyroid carcinoma and underwent total thyroidectomy. After the surgery, she received L-T4 therapy, but her TSH levels remained elevated. MRI was performed on the brain, but no lesions were found in the pituitary gland. Therefore, she was tested for TRβ gene, and a previously defined mutation, P453S, was detected. Ultimately, she was diagnosed as RTH and treated with L-T4. In this case, the dose of L-T4 needed to be increased to suppress her TSH levels to the normal range or less, and to prevent stimulating malignant cells. Currently, her dose of L-T4 has been increased, and her TSH levels are still lower than normal, however, she has no thyrotoxic symptoms, recurrence or metastasis of thyroid cancer. The patient is currently under careful observation regarding her circulatory and physiological status. In addition, the results of treatment still need to be monitored and evaluated. J. Med. Invest. 62: 268-271, August, 2015

Idiopathic pulmonary fibrosis (IPF) is the most common idiopathic interstitial pneumonias. Lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P) are signaling lipids that evoke growth factor-like responses to many cells. Recent studies revealed the involvement of LPA and S1P in the pathology of IPF. In this study, we determined LPA, S1P and ceramide 1-phosphate (C1P) in peripheral blood plasma of IPF patients, and examined correlation to the vital capacity of lung (VC), an indicator of development of fibrosis. Blood plasma samples were taken from eleven patients with IPF and seven healthy volunteers. The lipids of the sample were extracted and subjected to liquid chromatography-tandem mass spectrometry for analysis. Results showed that there is a significant negative correlation between VC and plasma LPA levels, indicating that IPF patients with advanced fibrosis had higher concentration of LPA in their plasma. Average of S1P levels were significantly higher in IPF patients than those in healthy subjects. Although it is not statistically significant, a similar correlation trend that observed in LPA levels also found between VC and S1P levels. These results indicated that plasma LPA and S1P may be associated with deterioration of pulmonary function of IPF patients. J. Med. Invest. 69 : 196-203, August, 2022

Insulin resistance is one of the pathophysiological features of obesity and type 2 diabetes. Recent findings have linked insulin resistance to chronic low-grade inflammation in white adipose tissue. Excess storage of saturated fat in white adipose tissue due to a modern life style causes hypertrophy and hyperplasia of adipocytes, which exhibit attenuated insulin signaling due to their production and release of saturated fatty acids. These adipocytes recruit macrophages to white adipose tissue and, together with them, initiate a proinflammatory response. Proinflammatory factors and saturated fatty acids secreted into the bloodstream from white adipose tissue impair insulin signaling in non-adipose tissues, which causes whole-body insulin resistance.

Purpose:Drug-induced interstitial pneumonia (DIP) that occurs during chemotherapy for breast cancer is a rare but a serious adverse event. Treatments of DIP requires interruption of breast cancer treatment, which may affect the patient’s prognosis. However, there are few reports which discuss DIP during breast cancer treatments. Purpose of this report is to make clear how DIP occurred and influenced breast cancer treatment in our hospital. Patients and Methods:A total of 74 patients who started perioperative chemotherapy in Tokushima Municipal Hospital for breast cancer from January 2019 to December 2020 were evaluated for DIP. Patients’ and tumors’ characteristics, and regimens which caused DIP were investigated. The clinical courses of the DIP patients were also followed up. Results:Twelve of the 74 patients developed DIP. All 12 patients had histories of cyclophosphamide administration;however, the causative drug could not be determined. Ten of the 12 patients were treated with steroids, and all the patients recovered ultimately from the interstitial pneumonia. While chemotherapy was administered in six patients after mild DIP, no relapse of pneumonia was observed. Conclusion:DIP during perioperative chemotherapy for breast cancer was resolved with appropriate treatment. Patients were able to resume breast cancer treatment with minimal interruption. J. Med. Invest. 69 : 107-111, February, 2022

Objective. There is evidence that multiple sclerosis (MS) is not only characterized by immune mediated inflammatory reactions but also by neurodegenerative processes. Neutralization of oxidative stress and excitotoxicity, might represent a therapeutic approach to provide neuroprotection in MS. The purpose of this study was to compare changes in total antioxidative status and activities of chosen antioxidative enzymes, such as: SOD, CAT in erythrocytes of patients with MS before and after using WBCT with control group. Materials and methods. 32 patients with multiple sclerosis (ICD10-G35) and 20 healthy subjects were recruited for the study. The examined MS group (n=16) was treated with a series of 10 daily exposures in a cryogenic chamber (2-3 min, from -120°C to -110°C) and program of exercises. The control MS group (n=16) had only exercises. Plasma TAS as well as SOD and CAT activities in erythrocytes were measured. Results. The level of TAS in MS patients was distinctly reduced compared to healthy subjects. After two weeks of WBCT treatment an increase of TAS in the whole examined group (p>0,01) were observed in relation to control MS group. There was not increase of CuZnSOD and CAT activities. Conclusion. Our results suggest positive antioxidant effects of WBCT as a short-term adjuvant treatment for patients suffered due to MS. J. Med. Invest. 57: 168-173, February, 2010

The purpose of this study was to clarify the influence of different postures on the activity of the shoulder girdle and lower back muscles while using a smartphone. Sixteen healthy male participants maintained two postures while using a smartphone : a good posture in which the tragus and acromion were closer to the vertical line passing through the greater trochanter, and a poor posture in which the tragus and acromion were farther from the vertical line passing through the greater trochanter. The target muscles were the rhomboid major (Rhom), upper trapezius, middle trapezius, lower trapezius (LT), lumbar erector spinae (LES), and lumbar multifidus (LMF). The activities of the Rhom and LT were significantly lower with poor posture than those with good posture. The activities of LES and LMF were significantly higher with poor posture than those with good posture. The results of this study indicated that poor posture was associated with hypoactivity of the shoulder girdle muscles and hyperactivity of the lower back muscles when compared with good posture. Poor posture for prolonged periods while using a smartphone would lead to malfunction of the shoulder girdle muscles and musculofascial lower back pain. J. Med. Invest. 67 : 274-279, August, 2020

Background: The thermic effect of food (TEF) is higher in lean than in obese human subjects.Objective: Relationships between TEF and insulin resistance during meals, from the point of view of autonomic nervous activity, were evaluated.Methods: Autonomic nervous activity was evaluated in 20 young adults using the spectral analysis of heart rate variability from one hour before to two hours after a meal. Heart rate data were analyzed based on low frequency components (LF power, 0.04-0.15 Hz), high frequency components (HF power, 0.15-0.40 Hz), and LF/HF ratios. Energy expenditure and the TEF were measured 30 min after a meal. Homeostasis model of insulin resistance index (HOMA-IR) was also measured.Results: The LF/HF ratio was significantly increased 30 min after a meal (p<0.05). No correlation between LF power and HF power with TEF was found, but the LF/HF ratio was significantly and positively correlated with TEF (r=+0.56, p<0.05). Moreover, a significant negative correlation was found between the HOMA-IR and TEF (r=-0.601, p<0.05).Conclusions: The findings suggest that a reduction in insulin sensitivity induces a poor response of sympathetic nervous activity in the postprandial phase and a reduction in postprandial energy expenditure.

Spontaneously Running Tokushima Shikoku (SPORTS) rat is a hyperactive rat strain. However, the causative mutation of this phenotype has not yet been identified. To investigate the molecular basis for the unique phenotype of SPORTS rats, we examined gene-expression profiles by microarray analyses. Among adenylate kinase isozymes that maintain the homeostasis of cellular adenine nucleotide composition in the cell, only adenylate kinase 1 is highly up-regulated in both exercised and sedentary SPORTS rats compared with wild-type (WT) rats, 5.5-fold and 3.3-fold, respectively. Further comparative analyses revealed that genes involved in glucose metabolism were up-regulated in skeletal muscle tissue of exercised SPORTS rats compared with sedentary mutants, whereas genes related to extracellular matrix or region were down-regulated compared with WT rats. In brain tissue of sedentary SPORTS rats, genes associated with defense and catecholamine metabolism were highly expressed compared with WT rats. These findings suggest that genetic mutation(s) in SPORTS rat remodels metabolic demands through differentially regulating gene expression regardless of exercise. Therefore, the SPORTS rats are useful animal model not only for further examining the effects of exercise on metabolism but also for deeply studying the molecular basis how mutation affect the psychological motivation with spontaneous voluntary exercise phenotype.

NC/Nga (NC) mice are an animal model for human atopic dermatitis. We found that induction of antigen (Ag)-specific T cell response is diminished in ovalbumin (OVA)-immunized NC mice. Ability of Ag presentation in NC mouse dendritic cells (DCs) was significantly weaker than that in BALB/c and DBA/2 mouse DCs. Expression levels of MHC class II molecules and cathepsin E in NC mouse DCs were significantly lower that those in BALB/c and DBA/2 mouse DCs. These results indicate that low expression levels of MHC class II and cathepsin E might contribute to the defect in induction of Ag-specific T cells in NC mice. J. Med.

Background: Consumption of polyunsaturated fatty acids (PUFA) improves the lipid metabolism of diabetics, leading to prevents of arteriosclerosis. Exact relationship between saturated fatty acids (SFA) or PUFA and the insulin resistance of diabetics are unknown.Subjects and Methods: We investigated the relationship between the serum concentrations of saturated and unsaturated fatty acids and the homeostasis model insulin resistance index (HOMA-R) in Japanese patients with type 2 diabetes mellitus.Results: The SFA, i.e., lauric acid, myristic acid, palmitic acid, and stearic acid; the monounsaturated fatty acids (MUFA), i.e., palmitoleic acid, oleic acid, and erucic acid; and the PUFA, i.e., eicosadienoic acid, dihomo-γ-linolenic acid, docosatetraenoic acid, and docosapentaenoic acid were positively correlated with HOMA-R. However, no correlations were found between HOMA-R and SFA, i.e., arachidic acid, behenic acid, and lignoceric acid; the MUFA, i.e., eicosenoic acid and nervonic acid; and the PUFA, i.e., linoleic acid, γ-linolenic acid, linolenic acid, 5-8-11 eicosatrienoic acid, arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid.Conclusions: Some PUFA as well as SFA were positively correlated with HOMA-R. These results indicate that the intake of diet fatty acid must be well balanced in diabetic patients and it is not always true to refrain from taking SFA and increase the unsaturated fatty acids in their diets.

Telenursing is one type of telehealth service delivery proposed to resolve the predicted gap between healthcare workforce demand and supply globally. The aim of this article is to explore the ‘Nurse Chatbot' for chronic care on the benefits of increasing patient/client access to healthcare information and maximizing the potential of artificial intelligence/AI to bridge the ‘demand-supply gap' of human healthcare providers. Moreover,closing this gap through the establishment of a ‘Nurse Chatbot' will be innovative, favorably scalable and customizable within a decentralized health network, and potentially sustainable in the new digital economy. Following are the assumptions : 1) “caring” communicated textually is highly ‘transactive' in chronic disease selfmanagement support/CDSMS for goal agreements between agents and for overcoming the system noise in the form of cross-entropy, perplexity, and information wastage ; 2) ‘Nurse Chatbot' is the interlocutor in nursing care and the nursing agency by superpositioning and entanglement ; and 3) possible effects of chatbot-user transactions are information flows, management of health, and patient satisfaction. This article also looks into ‘Nurse Chatbot' development for CDSMS, simulation of its diffusion capacity egocentrically, technology acceptance model/TAM to inquire the engagement of users, and possible approaches to ethical and safety issues.
