High visceral fat with low subcutaneous fat accumulation as a determinant of atherosclerosis in patients with type 2 diabetes.

BACKGROUND: Abdominal visceral obesity has been reported to be associated with cardiovascular risks than body mass index, waist circumference, and abdominal subcutaneous fat. On the other hand, there is evidence that subcutaneous fat has a beneficial role against cardio-metabolic risks such as diabetes or dyslipidemia. However, little is known regarding the association between high visceral fat with low subcutaneous fat accumulation and the risk for atherosclerosis. METHODS: This study was designed to elucidate whether high visceral fat with low subcutaneous fat accumulation enhances the risk for atherosclerosis in patients with type 2 diabetes. This is a cross-sectional study of 148 patients with type 2 diabetes (mean age 65 ± 12 years; 44.5% female). Visceral fat area (VFA, cm(2)) and subcutaneous fat area (SFA, cm(2)) were assessed by abdominal computed tomography. Carotid intima media thickness (CIMT, mm) measured by ultrasonography was used for the assessment of atherosclerosis. Patients were divided into four groups: SFA < 100 cm(2) and VFA < 100 cm(2) [S(-)V(-)], SFA ≥ 100 cm(2) and VFA < 100 cm(2) [S(+)V(-)], SFA < 100 cm(2) and VFA ≥ 100 cm(2) [S(-)V(+)], and SFA ≥ 100 cm(2) and VFA ≥ 100 cm(2) [S(+)V(+)]. Linear regression analysis with a stepwise procedure was used for the statistical analyses. RESULTS: Among the patients examined, 16.3% were S(-)V(+). Mean (95 % confidence interval) of CIMT adjusting for age and gender were 0.80 (0.69-0.91), 0.86 (0.72-1.01), 1.28 (1.11-1.44) and 0.83 (0.77-0.88) in patients with S(-)V(-), S(+)V(-), S(-)V(+) and S(+)V(+), respectively (p < 0.001). The S(-)V(+) patients exhibited significantly older than S(-)V(-) patients and those with S(+)V(+) and had a highest VFA-SFA ratio (V/S ratio) among the four groups. S(-)V(+) patients were male predominant (100% male), and S(+)V(-) patients showed female predominance (82% female). In multivariate linear regression analysis (Adjusted R(2) = 0.549), S(-)V(+) was significantly associated with CIMT (Standardized ß 0.423, p < 0.001). Notably, S(+)V(+) was inversely associated with CIMT in the multivariate model. CONCLUSIONS: This study provides evidence that high visceral fat with low subcutaneous fat accumulation is an important determinant of carotid atherosclerosis and high subcutaneous fat could be protective against atherosclerosis in patients with type 2 diabetes.

Adrenal infarction with latent myelodysplastic/myeloproliferative neoplasm, unclassifiable with JAK2V617F mutation.

Key Clinical Message: Hematopoietic neoplasms can cause adrenal infarction. In cases of thrombosis occurring at uncommon sites, it is necessary to consider evaluating for the JAK2V617F mutation, even in the absence of notable abnormalities in blood counts. Abstract: Adrenal infarction, a rare ailment, has been sporadically linked to hematopoietic neoplasms. A 46-year-old male encountered left adrenal infarction, which coincided with a progressive rise in platelet counts. Subsequent diagnosis revealed myelodysplastic/myeloproliferative neoplasm-unclassifiable, featuring a JAK2V617F mutation. Simultaneously, the patient manifested multiple arteriovenous thromboses, necessitating treatment with edoxaban, aspirin, and hydroxyurea. Following thrombosis resolution, he was transferred to a transplantation center. This report delves into the thrombogenicity linked to the JAK2V617F mutation, while also examining documented instances of adrenal infarction in myeloid neoplasms. We should consider evaluating for JAK2V617F mutation even in cases of thrombosis at unusual sites, including adrenal infarction, even if there are no considerable abnormalities in blood counts.

Association of drugs with special caution in the guidelines with falls: A case-control and case-crossover study in Japan.

AIM: To determine the relationship between multiple medications and falls. METHODS: This case-control and case-crossover study was carried out at Kudanzaka Hospital in Chiyoda, Tokyo, Japan. A total of 325 patients who experienced their first falls when hospitalized between January 2016 and November 2018, and 1285 controls matched by sex, age and clinical departments were included in this study. Hospitalization duration and fall risk score were adjusted for in the analyses. RESULTS: In the case-control study, multivariable logistic regression showed that increasing the intake of oral medications was not significantly associated with the incidence of falls (odds ratio 1.02, 95% confidence interval 0.998-1.049). In contrast, drugs prescribed with special caution in accordance with the Elderly Oral Medication Guidelines were significantly associated with falls (odds ratio 1.17, 95% confidence interval 1.09-1.26). A similar pattern was observed in the case-crossover analysis. Among the drugs to be prescribed with special caution according to the guidelines, atypical antipsychotics, non-benzodiazepine hypnotics and magnesium oxide were significantly associated with the risk of falls. CONCLUSION: The drugs to be prescribed with special caution according to the guidelines were associated with an increased fall risk. The risk of falls in hospitalized older people due to multiple medications varies among medications. Geriatr Gerontol Int ••; ••: ••-•• Geriatr Gerontol Int 2021; ••: ••-••.

Non-GABA sleep medications, suvorexant as risk factors for falls: Case-control and case-crossover study.

The aim of this study was to examine the risk of falls associated with the use of non-gamma amino butyric acid (GABA) sleep medications, suvorexant and ramelteon. This case-control and case-crossover study was performed at the Kudanzaka Hospital, Chiyoda Ward, Tokyo. A total of 325 patients who had falls and 1295 controls matched by sex and age were included. The inclusion criteria for the case group were hospitalized patients who had their first fall and that for the control were patients who were hospitalized and did not have a fall, between January 2016 and November 2018. The internal sleep medications administered were classified as suvorexant, ramelteon, non-benzodiazepines, benzodiazepines, or kampo. In the case-control study, age, sex, clinical department, the fall down risk score, and hospitalized duration were adjusted in the logistic regression model. In the case-control study, multivariable logistic regression showed that the use of suvorexant (odds ratio [OR]: 2.61, 95% confidence interval [CI]: 1.29-5.28), nonbenzodiazepines (OR: 2.49, 95% CI: 1.73-3.59), and benzodiazepines (OR: 1.65, 95% CI: 1.16-2.34) was significantly associated with an increased OR of falls. However, the use of ramelteon (OR: 1.40, 95% CI: 0.60-3.16) and kampo (OR: 1.55, 95% CI: 0.75-3.19) was not significantly associated with an increased OR of falls. In the case-crossover study, the use of suvorexant (OR: 1.78, 95% CI: 1.05-3.00) and nonbenzodiazepines (OR: 1.63, 95% CI: 1.17-2.27) was significantly associated with an increased OR of falls. Similar patterns were observed in several sensitivity analyses. It was suggested that suvorexant increases the OR of falls. This result is robust in various analyses. This study showed that the risk of falls also exists for non-GABA sleep medication, suvorexant, and thus it is necessary to carefully prescribe hypnotic drugs under appropriate assessment.

Two cases of type 2 diabetes mellitus in elderly patients successfully treated with monthly exenatide long-acting release.

Two elderly patients with poorly controlled type 2 diabetes mellitus had difficulty self-managing their medications. Exenatide long-acting release (LAR), with an extended administration interval of 1 month, maintained hemoglobin A1c (HbA1c) level in the 7% range. Monthly administration of exenatide-LAR may be considered for use in carefully selected elderly individuals.

Increased visceral adiposity with normal weight is associated with the prevalence of non-alcoholic fatty liver disease in Japanese patients with type 2 diabetes.

AIMS/INTRODUCTION: To investigate the impact of increased visceral adiposity with normal weight (OB[-]VA[+]) on the prevalence of non-alcoholic fatty liver disease in patients with type 2 diabetes. MATERIALS AND METHODS: This was a cross-sectional study of 140 Japanese patients with type 2 diabetes (mean age 65 ± 11 year; 44.6% women). Visceral fat area (VFA; cm(2) ) and liver attenuation index (LAI) were assessed by abdominal computed tomography. The patients were divided into four groups by VFA and body mass index (BMI; kg/m(2) ) as follows: BMI <25 kg/m(2) and VFA <100 cm(2) (OB[-]VA[-]), BMI ≥25 kg/m(2) and VFA <100 cm(2) (OB[+]VA[-]), BMI <25 kg/m(2) and VFA ≥100 cm(2) (OB[-]VA[+]), and BMI ≥25 kg/m(2) and VFA ≥100 cm(2) (OB[+]VA[+]). Multivariate linear regression and logistic regression analysis were carried out to determine the impact of OB(-)VA(+) on LAI. RESULTS: In the present study, 25.0% were OB(-)VA(+) patients, where the LAI levels were lower (1.09 ± 0.22) than those in OB(-)VA(-) patients (1.23 ± 0.15), and were equivalent to those in OB(+)VA(+) patients (1.03 ± 0.26). In multivariate linear regression analysis, OB(-)VA(+) was independently associated with LAI (standardized ß-0.212, P = 0.014). In multivariate logistic regression analysis, OB(-)VA(+) was a significant predictor of LAI <0.9 (odds ratio 5.88, 95% confidence interval 1.03-33.52, P = 0.046). CONCLUSIONS: The present study provides evidence that increased visceral adiposity with normal weight is a strong predictor for the prevalence of non-alcoholic fatty liver disease in Japanese patients with type 2 diabetes.

Retrograde pyelonephritis and lumbar spondylitis as a result of Salmonella typhi in a type 2 diabetes patient with neurogenic bladder.

We present a case of a 62-year-old diabetic woman with acute pyelonephritis and spondylitis caused by Salmonella typhi. She was admitted to Tokyo Medical Dental University Hospital, Tokyo, Japan, because of unconsciousness and was diagnosed with sepsis by retrograde pyelonephritis as a result of Salmonella typhi. Antibiotics treatment was immediately started; however, she subsequently developed lumbar spondylitis, and long-term conservative treatment with antibiotics and a fixing device were required. This is the first report of a diabetic patient who developed retrograde urinary tract infection with Salmonella typhi, followed by sepsis and spondylitis. The infection could be a result of diabetic neuropathy, presenting neurogenic bladder and hydronephrosis. The patient was successfully treated with antibiotics and became asymptomatic with normal inflammatory marker levels, and no clinical sign of recurrence was observed in the kidney and spine at 4 months.

Impact of increased visceral adiposity with normal weight on the progression of arterial stiffness in Japanese patients with type 2 diabetes.

OBJECTIVE: Normal-weight abdominal obesity has been reported to be associated with poor mortality. We aimed to investigate the impact of increased visceral adiposity with normal weight (OB(-)VA(+)) on the progression of arterial stiffness in patients with type 2 diabetes. METHODS: This was a cross-sectional study of 414 patients with type 2 diabetes (mean age 64±12 years; 40.3% female). Visceral fat area (VFA, cm(2)) was measured by a dual bioelectrical impedance analyzer. Arterial stiffness was assessed by brachial-ankle pulse wave velocity (baPWV, cm/s). Patients were divided into four groups by VFA and body mass index (BMI, kg/m(2)) as the following: BMI<25 kg/m(2) and VFA<100 cm(2) (obesity (OB)(-)visceral adiposity (VA)(-)), BMI≥25 kg/m(2) and VFA<100 cm(2) (OB(+)VA(-)), BMI<25 kg/m(2) and VFA≥100 cm(2) (OB(-)VA(+)), and BMI≥25 kg/m(2) and VFA≥100 cm(2) (OB(+)VA(+)). Multivariate linear regression analysis was done to determine the impact of OB(-)VA(+) on arterial stiffness. RESULTS: Among the patients, 7.2% were OB(-)VA(+) with higher baPWV levels (1956±444 cm/s) than those with OB(+)VA(-) (1671±416 cm/s, p=0.014), those with OB(+)VA(+) (1744±317 cm/s, p=0.048), and those with OB(-)VA(-) (1620±397 cm/s, p=0.024). In multivariate linear regression analysis, OB(-)VA(+) remained independently associated with baPWV (standardized ß 0.184, p=0.001). CONCLUSIONS: This study provides evidence for the burden of arterial stiffness in OB(-)VA(+) patients with type 2 diabetes; therefore, evaluation of visceral adiposity is of clinical relevance for the better management of non-obese individuals as well as obese populations.
