Objective: To study the relationship between the amount of surgery-induced gastric volume reduction and long-term weight loss and glucose tolerance. Background Data: Vertical sleeve gastrectomy (VSG) has recently surpassed gastric bypass to become the most popular surgical intervention to induce sustained weight loss. Besides inducing significant weight loss, VSG also improves glucose tolerance. Although no clear correlation has been observed between the size of the residual stomach and sustained weight loss, this begs the question whether less aggressive gastric volume reduction may provide sufficient efficacy when weight loss is not the major goal of the surgical intervention. Methods: A series of strategies to reduce gastric volume were developed and tested in Long Evans male rats, namely: VSG, Fundal (F)-Resection, Gastric Sleeve Plication (GSP), Fundal-Plication, and Fundal-Constrained. Results: All surgical interventions resulted in a reduction of gastric volume relative to sham, but none of the interventions were as effective as the VSG. Gastric volume was linearly correlated to increased gastric emptying rate as well as increased GLP-1 response. Overall, cumulative food intake was the strongest correlate to weight loss and was logarithmically related to gastric volume. Regression modeling revealed a nonlinear inverse relation between body weight reduction and gastric volume, confirming that VSG is the only effective long-term weight loss strategy among the experimental operations tested. Conclusions: The data suggest a minimum threshold volume of the residual stomach that is necessary to induce sustained weight loss. Although all gastric volume interventions increased the GLP-1 response, none of the interventions, except VSG, significantly improved glucose tolerance. In conclusion, if weight loss is the primary goal of surgical intervention, significant volume reduction is required, and this most likely requires excising gastric tissue.

ADA decreases after SG, particularly in postmenopausal patients. Software-generated ADA may be more accurate than radiologist-estimated BD or breast imaging reporting and data system for capturing changes in dense breast tissue after SG.

Pediatric ocular burns carry a risk of permanent vision impairment. This study identifies risk factors that place these patients at high risk of permanent visual complications. A retrospective review was conducted in our academic urban pediatric burn center. All 300 patients under 18 years of age admitted from January 2010 to December 2020 with periorbital or ocular thermal injuries were included. Variables analyzed included patient demographics, burn characteristics, ophthalmology consultation, ocular exam findings, follow up time period, and early and late ocular complications. Etiologies of burn injuries were as follows: 112 (37.5%) scald, 80 (26.8%) flame, 35 (11.7%) contact, 31 (10.4%) chemical, 28 (9.4%) grease, and 13 (4.3%) friction. Overall, 207 (70.9%) patients with ocular burns received an ophthalmology consult. Of these patients, 61.5% had periorbital cutaneous burns and 39.8% had corneal injuries, and only 61 (29.5%) presented for a follow-up visit. Ultimately, 6 had serious ocular sequelae, including ectropion, entropion, symblepharon, and corneal decompensation. While thermal burns involving the ocular surface and eyelid margins are relatively infrequent overall, they carry a small risk of serious to long-term sequelae. Recognizing those at greatest risk, and initiating appropriate early intervention is critical.

Introduction Pediatric burns commonly involve the face and periocular areas, with a risk of impairing vision. The aim of this study is to characterize ocular injuries in burn patients and identify the patients at most risk of ocular complications. Methods This study is a retrospective review within a single academic, urban pediatric burn center. All burn patients under 18 years of age admitted from January 2010 to December 2020 with periorbital or ocular involvement were included. Variables analyzed included patient demographics, burn characteristics, presence of ophthalmology consultation, ocular exam findings, follow up time period, and early and late ocular complications. Results In the study period, 2,781 patients were admitted to our burn center, 300 of whom had facial burns involving the eyes and/or eyelids. Etiologies of burn injuries were as follows: 112 (37.5%) scald, 80 (26.8%) flame, 35 (11.7%) contact, 31 (10.4%) chemical, 28 (9.4%) grease, and 13 (4.3%) friction. Overall, 70.9% of patients with ocular burns received an ophthalmology consult. Of these patients, 61.5% had periorbital swelling and 39.8% had corneal injuries. Of the 207 patients who were followed as inpatients by ophthalmology, only 61 (29.5%) presented for a follow-up visit, as recommended, 6 of which had serious ocular sequelae including ectropion, entropion, symblepharon, and corneal decompensation, and 4 of whom had a firework-related injury. Conclusions While burns involving the ocular surface and eyelid margins are infrequent overall, they can lead to long-term sequelae. Ophthalmology consultation is critical, particularly in the setting of chemical and firework-related injury. As ocular and periocular burns can cause immediate as well as delayed sequelae, ophthalmologic evaluation is a key component of assessment. Applicability of Research to Practice This paper characterizes ocular injuries in pediatric patients with facial burn injuries and identifies patients most at risk for ocular complications. We believe this will be valuable for many burn researchers and clinicians in order to better identify patients who could benefit from ophthalmologic evaluation and those at risk for both immediate as well as delayed sequelae from periocular burns.
