ABSTRACT
This case study provides evidence that homeostatic control in a patient with hyperglycemia and other metabolic abnormalities associated with insulin resistance can be rapidly restored utilizing lifestyle therapy. The patient, an overweight, non-Hispanic White male aged 70 years, had been medicated for hypertension and Type 2 diabetes mellitus for 12 years. From baseline during 21 months of follow-up, HbA1c decreased from 6.6% to 5.4%, mean fasting glucose decreased from 125 mg/dL to 94 mg/dL, blood pressure decreased from 130/85 mmHg to 100/64 mmHg, estimated glomerular filtration rate increased from 50 ml/min/1.73m² to 58 ml/min/1.73m², waist circumference decreased from 118.8 cm to 90.8 cm, and liver function improved with aspartate transaminase decreasing from 44 IU/L to 17 IU/L and alanine transaminase decreasing from 34 IU/L to 21 IU/L. Each of these metabolic corrections was observed while eliminating respective disease-specific medications. These metabolic improvements were achieved using primary recommended lifestyle therapy specifically targeting known insulinemic lifestyle components. This case study shows that the utilization of primary recommended, ongoing lifestyle therapy targeting insulinemic lifestyle components can rapidly improve markers of insulin resistance and normalize abnormal laboratory values while eliminating the risk of polypharmacy and the direct costs of medication.
ABSTRACT
Introduction: This article reports the evaluation of a personalized, team-based comprehensive lifestyle modification program targeting known triggers of hyperinsulinemia and insulin resistance. Methods: A retrospective chart review was undertaken for 536 participants in a novel high-intensity lifestyle behavioral modification program. Surrogate markers of insulin resistance and metabolic syndromeârelated pathologies were measured before and after participation in the the program. Results: Reversal of metabolic syndrome was present in 42% of participants who met the criteria for this syndrome. Additional changes seen in this cohort include: 36% decrease in triglyceride to high-density lipoprotein cholesterol ratio; 5% (-7.2 mm Hg) decrease in systolic blood pressure and 4% (-3.8 mm Hg) decrease in diastolic blood pressure; decreased abdominal adiposity and waist circumference (-7.6 cm); increased high-density lipoprotein cholesterol (1.3 mg/dL); and 23% (-57.1 mg/dL) decrease in serum triglycerides. Hyperglycemia was normalized in 35% of participants with prediabetes. Only 2% of those with prediabetes progressed to type 2 diabetes mellitus. Among those with type 2 diabetes mellitus, 46% experienced a reduction in HbA1c to below diabetic cut offs. Compared to baseline, the Metabolic Syndrome Severity Score decreased by 30% among those with metabolic syndrome, 11% among those with prediabetes, 26% among those with type 2 diabetes mellitus, and 38% among those with uncontrolled type 2 diabetes mellitus. Cardiorespiratory fitness, measured by the calculated Metabolic Equivalent of Task maximum, increased by 30% in the metabolic syndrome cohort, 28% in the prediabetic cohort, 29% in the type 2 diabetes mellitus cohort, 29% in the uncontrolled type 2 diabetes mellitus cohort, and 32% in the cohort with obesity. Conclusion: Modifying lifestyle factors that trigger hyperinsulinemia provided pleiotropic improvements to all measured surrogate markers of insulin resistance, mitigated the progressive nature of the insulin resistance and metabolic syndromeârelated chronic pathologies, reduced Metabolic Syndrome Severity Score, and improved cardiorespiratory fitness. These results suggest that earlier identification of the diagnostic criteria of metabolic syndrome and/or Metabolic Syndrome Severity Score and the prompt initiation of a comprehensive therapeutic lifestyle approach would significantly mitigate disease burden.
ABSTRACT
The development of collateral circulation is a general vascular response which is well characterised in the heart. The most common precipitant of this is ischaemia and the most common manifestation is intra coronary collateralisation. Collateral flow between the heart and other thoracic structures is also documented albeit rarely and can be congenital or acquired. In this case report we define a unique case of collateral flow between the coronary and pulmonary circulations in a complex case of mediastinal fibrosis.
