RESUMO
IN BRIEF This article describes a single-center, retrospective chart review to determine the glycemic effect of converting from U-100 to U-500 regular insulin in veterans with type 2 diabetes and the effect of this change, if any, on the frequency of provider contacts. Results showed that U-500 insulin improved glycemic control without significantly increasing the risk of hypoglycemia or total daily insulin dose, even when follow-up contacts with providers were not structured or frequent.
RESUMO
Introduction Achilles tendon ruptures (ATRs) have classically been thought to affect the middle-aged "weekend warrior" participating in basketball, volleyball, soccer, or any ground sport; however, with a more active elderly population, these tears are becoming more common in older patients. We sought to examine the role of demographics, tear location, and operative technique for acute Achilles tendon ruptures treated surgically. Methods A retrospective query was performed to identify patients who presented with Achilles tendon ruptures. Inclusion data were primary end-to-end repairs, augmented repairs with flexor hallucis longus (FHL) transfers, augmented repairs with graft, augmented repairs with both FHL transfer and graft use, isolated FHL transfers, and revision Achilles tendon procedures. Demographics and tear locations were collected and analyzed. Results Midsubstance tears were the most common tear location occurring in 237 of 286 (82.9%) patients. Distal insertional tears of the Achilles tendon were treated in 35 (12.2%) patients, while 14 (4.9%) patients had a more proximal tear located at the myotendinous junction. Older patients (average age: 53.3±12.5) had significantly more distal insertional tears (p<0.001), while younger patients (average age: 35.1±7.4) presented with significantly more tears at the myotendinous junction (p<0.001). The average BMI was significantly higher (average BMI: 32.2±6.6; p<0.001) in patients with distal insertional tears compared to midsubstance and proximal tears (28.5±4.6 and 28.5±5.3, respectively). There was a higher percentage of diabetic patients who underwent operative treatment for distal insertional tears (20%) compared to midsubstance tears (7.2%). Conclusion The findings of our study suggest that a subset of patients, particularly those with advanced age and higher BMI, is more likely to present with a distal Achilles tendon rupture. Additionally, patients in our series who had distal tears more commonly required an augmented repair technique. Our results highlight the need for future research to further define the relationship between increasing age and higher BMI patients sustaining distal tears more often than midsubstance tears.
