Evaluating Insulin/Glucose Ratio Using Breakfast of Calorie Restriction Meal for Type 2 Diabetes Mellitus

Background: Type 2 diabetes mellitus (T2DM) has been a medical and social problem worldwide. For nutritional therapy, Low Carbohydrate Diet (LCD) and Calorie restriction (CR) have discussed for long, where authors continued clinical research. Subjects and Methods: Subjects were 68 patients with T2DM with 62.1 years on average. Methods included i) standard CR was provided a day with 1400 kcal and 60% of carbohydrate, ii) measurement of daily profile of blood glucose, iii) insulinogenic index (IGI) (0-30 mins) exam for breakfast including 70g of carbohydrate, iv) calculation of IGI by delta and Area Under the Curves(AUC). Results: Basal data revealed that HbA1c 7.9%, fasting glucose 163 mg/dL, average glucose in a day 210 mg/dL, M value 117 in the median. Increment of glucose/IRI was 48.0 mg/dL/8.6 μU/mL, respectively. Delta or AUC ratio of IGI was 0.14[0.08-0.26] and 3.3[2.5-5.2], respectively. There were significant correlations between M value and Delta or AUC ratio, with a higher coefficient in the latter. Discussion and Conclusion: IGI study in Meal Tolerance Test (MTT) would be useful for pancreas function evaluation. AUC ratio method has superiority than Delta ratio with higher correlation coefficient. Current results could be the fundamental data for the related range of research, and further development will be expected

Useful Measurement of Glucose Variability by Flash Glucose Monitoring (FGM) with the Efficacy of Sodium-Glucose Cotransporter 2 (SGLT2) Inhibitor

Diabetes has been a crucial medical and social problem worldwide. For adequate nutritional therapy, there have been discussions concerning Calorie Restriction (CR) and Low Carbohydrate Diet (LCD). We have investigated glucose variability of diabetic patients applying CR, LCD, continuous glucose monitoring (CGM) and applied FreeStyle Libre which is flash glucose monitoring (FGM). The patient is a 40-year-old female with type 2 diabetes mellitus (T2DM), who showed BMI 20.7, postprandial blood glucose 257 mg/dL. HbA1c 12.1%, Glycoalbumin 31.6% (11.6-16.4), serum C-peptide 2.0 ng/ml and unremarkable data of liver function, renal, lipids. She was provided the intervention of three stages, which are i) CR with 60% carbohydrate in Day 1-2, ii) LCD meal with 12% carbohydrate in Day 3-5; iii) LCD + Sodium-glucose cotransporter 2 (SGLT2) inhibitor (Ipragliflozin L-Proline 50mg) in Day 6-12. The glucose profile was measured by FreeStyle Libre Pro (Abbott) for 14 days. The daily profile of blood glucose was abruptly decreased on Day 6. Time percentage of satisfactory blood glucose 70-180 mg/dL (/24h) was 0%, 0%, 2%, 14%, 0%, 54%, 100% in Day 1-7, respectively. These results suppose the acute clinical efficacy of SGLT2 inhibitor, and this report would become a reference for future diabetic practice and research

Index of C-peptide / glucose ratio for Carbo70 can be useful in clinical practice for diabetes

Background: Authors and colleagues have undertaken clinical research on Carbohydrate (CR) and Low Carbohydrate Diet (LCD) for years. We have proposed new evaluation method of insulinogenic index-carbohydrate 70g (IGI-carbo70). In similar way, C-peptide index for Carbohydrate-70 (CPI-Carbo70) is proposed in this report. Subjects and methods: The subjects were 37 patients with Type 2 diabetes mellitus (T2DM) and admitted for further evaluation and treatment. CR diet was provided on day 1 and 2, including 60% carbohydrates, 25% lipids and 15% protein with 1400 kcal/day. On day 2, breakfast with 70g of carbohydrate was provided, and glucose and C-peptide values were measured at 0 and 30 minutes. Results: Average HbA1c was 8.1 %, and Morbus (M) value was 70.5 in median. Glucose and C-peptide on 0--30min significantly increased as 163--195 mg/dL, 1.1--1.5μU/mL, respectively. CPI-Carbo70 was 1.94 in average and 1.54 in median. There were significant correlations between increments of glucose and C-peptide, and between HbA1c and CPI-Carbo70. Discussion and conclusion: CPI-Carbo70 was investigated and proposed. It may be useful for evaluating the function of the pancreas. This research would give the fundamental data for this field, and further research development will be expected in the future

Fractionated administration of irinotecan and cisplatin for treatment of lung cancer: a phase I study

A combination chemotherapy of irinotecan (CPT-11) and cisplatin (CDDP) has been reported to be active for lung cancer. In the previous trial, however, diarrhoea and leucopenia became the major obstacle for sufficient dose escalation of CPT-11 to improve the treatment outcome. We conducted a phase I study to investigate whether the fractionated administration of CDDP and CPT-11 at escalated dose was feasible and could improve the treatment outcome. Twenty-four previously untreated patients with unresectable non-small-cell lung cancer (NSCLC) or extensive disease of small-cell lung cancer (SCLC) were eligible. Both CDDP and CPT-11 were given on days 1 and 8, and repeated every 4 weeks. The dose of CDDP was fixed at 60 mg m−2 and given by 1-h infusion before CPT-11 administration. The starting dose of CPT-11 was 40 mg m−2, and the dose was escalated by an increase of 10 mg m−2. The maximally tolerated dose of CPT-11 was determined as 60 mg m−2 because grade 4 haematological or grade 3 or 4 non-haematological toxicities developed in six patients out of 11 patients evaluated. Diarrhoea became a dose-limiting toxicity. The objective response rates were 76% for NSCLC and 100% for SCLC. The recommended dose of CPT-11 and CDDP in a phase II study will be 50 mg m−2 and 60 mg m−2 respectively. © 1999 Cancer Research Campaig

Ruptured appendiceal cystadenoma presenting as right inguinal hernia in a patient with left colon cancer: A case report and review of literature

BACKGROUND: Mucoceles resulting from cystadenomas of the appendix are uncommon. Although rare, rupture of the mucoceles can occur with or without causing any abdominal complaint. There are several reports associating colonic malignancy with cystadenomas of the appendix. Herein, we report an unusual and interesting case of right inguinal hernia associated with left colon cancer. CASE PRESENTATION: A case of ruptured mucocele resulting from cystadenoma of the appendix was presented as right inguinal hernia in a 70-year-old male. The patient underwent colonoscopy, x-ray, ultrasound and computed tomography. Localized pseudomyxoma peritonei associated with adenocarcinoma of the descending colon was diagnosed. The patient underwent segmental resection of the colon, appendectomy, debridement of pseudomyxoma and closure of the internal ring of right inguinal canal. He is free of symptoms in one year follow-up. CONCLUSION: Synchronous colon cancer may occur in patients with appendiceal mucoceles. In such patients, the colon should be investigated and colonoscopy can be performed meticulously in cases of ruptured mucoceles and localized pseudomyxoma peritonei. Surgical intervention is the current choice of management

Bare Bones Pattern Formation: A Core Regulatory Network in Varying Geometries Reproduces Major Features of Vertebrate Limb Development and Evolution

BACKGROUND: Major unresolved questions regarding vertebrate limb development concern how the numbers of skeletal elements along the proximodistal (P-D) and anteroposterior (A-P) axes are determined and how the shape of a growing limb affects skeletal element formation. There is currently no generally accepted model for these patterning processes, but recent work on cartilage development (chondrogenesis) indicates that precartilage tissue self-organizes into nodular patterns by cell-molecular circuitry with local auto-activating and lateral inhibitory (LALI) properties. This process is played out in the developing limb in the context of a gradient of fibroblast growth factor (FGF) emanating from the apical ectodermal ridge (AER). RESULTS: We have simulated the behavior of the core chondrogenic mechanism of the developing limb in the presence of an FGF gradient using a novel computational environment that permits simulation of LALI systems in domains of varying shape and size. The model predicts the normal proximodistal pattern of skeletogenesis as well as distal truncations resulting from AER removal. Modifications of the model's parameters corresponding to plausible effects of Hox proteins and formins, and of the reshaping of the model limb, bud yielded simulated phenotypes resembling mutational and experimental variants of the limb. Hypothetical developmental scenarios reproduce skeletal morphologies with features of fossil limbs. CONCLUSIONS: The limb chondrogenic regulatory system operating in the presence of a gradient has an inherent, robust propensity to form limb-like skeletal structures. The bare bones framework can accommodate ancillary gene regulatory networks controlling limb bud shaping and establishment of Hox expression domains. This mechanism accounts for major features of the normal limb pattern and, under variant geometries and different parameter values, those of experimentally manipulated, genetically aberrant and evolutionary early forms, with no requirement for an independent system of positional information
