The DJBL is safe when implanted for 1 year, and results in significant weight loss and improvements in cardiometabolic risk factors. These results suggest that this device may be suitable for the treatment of morbid obesity and its related comorbidities. This study was registered at www.clinicaltrials.gov (NCT00985491).
The effectiveness of Roux-en-Y gastric bypass (RYGB) against obesity and its comorbidities has generated excitement about developing new, less invasive treatments that use the same molecular mechanisms. Although controversial, RYGB-induced improvement of metabolic function may not depend entirely upon weight loss. To elucidate the differences between RYGB and dieting, we studied several individual organ molecular responses and generated an integrative, interorgan view of organismal physiology. We also compared murine and human molecular signatures. We show that, although dieting and RYGB can bring about the same degree of weight loss, post-RYGB physiology is very different. RYGB induces distinct, organ-specific adaptations in a temporal pattern that is characterized by energetically demanding processes, which may be coordinated by HIF1a activation and the systemic repression of growth hormone receptor signaling. Many of these responses are conserved in rodents and humans and may contribute to the remarkable ability of surgery to induce and sustain metabolic improvement.
Routine preoperative endoscopy detects different abnormalities which need specific approach prior to surgery. Preoperative endoscopy should be performed to all patients prior to surgery.
In this prospective, multicentric, observational study, we describe the clinical characteristics and outcomes of people living with HIV (PLHIV) requiring hospitalization due to COVID-19 in Chile and compare them with Chilean general population admitted with SARS-CoV-2. Consecutive PLHIV admitted with COVID-19 in 23 hospitals, between 16 April and 23 June 2020, were included. Data of a temporally matched-hospitalized general population were used to compare demography, comorbidities, COVID-19 symptoms, and major outcomes. In total, 36 PLHIV subjects were enrolled; 92% were male and mean age was 44 years. Most patients (83%) were on antiretroviral therapy; mean CD4 count was 557 cells/mm3. Suppressed HIV viremia was found in 68% and 56% had, at least, one comorbidity. Severe COVID-19 occurred in 44.4%, intensive care was required in 22.2%, and five patients died (13.9%). No differences were seen between recovered and deceased patients in CD4 count, HIV viral load, or time since HIV diagnosis. Hypertension and cardiovascular disease were associated with a higher risk of death ( p = 0.02 and 0.006, respectively). Compared with general population, the HIV cohort had significantly more men (OR 0.15; IC 95% 0.07–0.31) and younger age (OR 8.68; IC 95% 2.66–28.31). In PLHIV, we found more intensive care unit admission (OR 2.31; IC 95% 1.05–5.07) but no differences in the need for mechanical ventilation or death. In this cohort of PLHIV hospitalized with COVID-19, hypertension and cardiovascular comorbidities, but not current HIV viro-immunologic status, were the most important risk factors for mortality. No differences were found between PLHIV and general population in the need for mechanical ventilation and death.
Our results demonstrate that SATs express higher 11beta-HSD1 mRNA levels than VAT. This finding highlights the importance of SAT in obesity and its possible role on metabolic disorders associated with obesity.
Summary and background data
Recent coronavirus outbreak and “stay at home” policies have accelerated the implementation of virtual healthcare. Many surgery departments are implementing telemedicine to enhance remote perioperative care. However, concern still arises regarding the safety of this modality in postoperative follow-up after gastrointestinal surgery. The aim of the present prospective study is to compare the use of telemedicine clinics to in-person follow-up for postoperative care after gastrointestinal surgery during COVID-19 outbreak.
Methods
Prospective study that included all abdominal surgery patients operated since the COVID-19 outbreak. On discharge, patients were given the option to perform their postoperative follow-up appointment by telemedicine or by in-person clinics. Demographic, perioperative, and follow-up variables were analyzed.
Results
Among 219 patients who underwent abdominal surgery, 106 (48%) had their postoperative follow-up using telemedicine. There were no differences in age, gender, ASA score, and COVID-19 positive rate between groups. Patients who preferred telemedicine over in-person follow-up were more likely to have undergone laparoscopic surgery (71% vs. 51%,
P
= 0.037) and emergency surgery (55% vs. 41%;
P
= 0.038). Morbidity rate for telemedicine and in-person group was 5.7% and 8%, (
P
= 0.50). Only 2.8% of patients needed an in-person visit following the telemedicine consult, and 1.9% visited the emergency department.
Conclusions
In the current pandemic, telemedicine follow-up can be safely and effectively performed in selected surgical patients. Patients who underwent laparoscopic and emergency procedures opted more for telemedicine than in-person follow-up.
