RESUMO
BACKGROUND: Optimizing nutrition is essential for recovery after major surgery or severe illness. Feeding tubes (FT) can be placed in patients limited by oral enteral nutrition. Given the myriad of locations in which these procedures are performed (radiology, intensive care unit, and endoscopy suite), routine follow-up is challenging. The purpose of this study was to evaluate the impact of an FT clinic on nutrition. We hypothesized that enrollment in the FT clinic would result in improved nutritional outcomes. METHODS: Retrospective review of Veteran Affairs Medical Center patients with FTs placed from January 2010 to January 2020. Demographics and body mass index (BMI) were recorded. Serum albumin recorded within 1 month of tube placement was compared to within 1 month of tube removal, death, or at the end of the study period. FT clinic participation required at least 2 visits. Indications for FT placement and duration were recorded. Patients were excluded when both BMI and albumin values were incomplete, and if FTs were placed for decompression. RESULTS: Ninety-three patients underwent FT placement during the study period; 5 (5%) were excluded. The average age was 64.8±9.7 years, with the majority being male, 85 patients (97%). Eighteen (20%) patients were seen in the FT clinic (FTC) and 70 (80%) were managed outside of FTC (nFTC). There were no differences in age, gender, or indication for FT. Mean albumin increased 0.42±0.85 g/dL in the FTC group versus -0.07±0.72 g/dL in the nFTC group ( P =0.037). The FTC group BMI increased, 0.38 kg/m 2 vs. -1.48 kg/m 2 in nFTC patients, P =0.041. The FTC patients maintained their tubes longer (36.5 vs. 7.0 mo, P =0.0014). CONCLUSIONS: Patients managed in a dedicated FT clinic experienced an improvement in their serum albumin values and increases in their BMI. In addition, they also maintained their FTs longer. To optimize nutrition and reduce weight loss, patients who require FTs should be enrolled in a dedicated FT clinic.

BACKGROUND: The Geriatric Surgery Verification Program (GSV) was developed to address perioperative care for patients ≥75 years, with a goal of improving outcomes and functional abilities after surgery. We sought to evaluate preoperative factors that place patients at risk for inability to return home (ie, discharge to a facility). METHODS: Retrospective review of patients ≥75 years old who underwent inpatient surgery from January 2018 to December 2022 at a referral Veterans Administration Medical Center enrolled in the GSV program. Preoperative factors included fall history, mobility aids, housing status, function, cognition, and nutritional status. Postoperative outcomes were discharge designations as home and home with services compared to a facility (skilled nursing facility and acute rehab). Exclusion criteria included preoperative facility residence, cardiac surgery, hospital transfer, postoperative complications, hospice discharge, or in-hospital mortality. RESULTS: 605 patients met inclusion criteria and 173 (29%) excluded as above. Of the remaining 432 patients, mean age was 79 ± 5 and the majority were male, 426 (99%). The majority of patients were discharged home, 388 (90%), compared to a facility, 44 (10%). Patients with a fall history (OR: 2.95, 95% CI: 1.56, 5.57), utilizing a mobility aid (OR: 6.0, 95% CI: 2.8, 12.83), were partial or totally dependent (OR: 4.83, 95% CI: 2.29, 10.17), or who lived alone (OR: 2.57, 95% CI: 1.08, 6.07) had higher rates of discharge to a facility. DISCUSSION: Preoperative mobility compromise and functional dependence are associated with higher rates of discharge to a facility. These preoperative factors are possibly modifiable with multidisciplinary care teams to decrease risks of facility placement.
RESUMO
Older adults who undergo major operations are at high risk for complications, disability, and death. The physio-social compromises unique to older adults are not routinely assessed and managed in the perioperative setting. Currently, the most practice-changing topic nationally in geriatric surgery is the implementation of comprehensive, multidisciplinary geriatric care pathways to provide age-friendly care for older adults throughout their perioperative course. This review presents three recently published articles focused on defining evidence-based outcomes associated with implementation of a comprehensive geriatric surgery program for older adults undergoing major inpatient operations. These studies serve as the initial evidence evaluating the efficacy and effectiveness of comprehensive perioperative geriatric surgery programs. Each study was chosen due to their high potential for meaningful impact for both clinicians and healthcare systems looking to improve their surgical care of older adults.

BACKGROUND: The ability to ambulate is an important indicator for wellness and quality of life. A major health event, such as a surgery, can derail this ability, and return to preoperative walking ability is a marker for recovery. Self-reported walking measurements by patients are subject to bias, thus wearable technology such as activity monitors have risen in popularity. We evaluated postoperative ambulation using an accelerometer in outpatient general surgery procedures with the hypothesis that those patients with less postoperative ambulation were at risk for adverse outcomes. METHODS: A retrospective review of patients undergoing outpatient abdominal surgeries from November 2016 to July 2019 at a Veteran Affairs Medical Center. Patients wore an accelerometer preoperatively and postoperatively to measure their ambulation (steps/day). Outcome measures were 30-day readmissions and Emergency Department (ED) utilization. Postoperative ambulation was defined as daily percentages of their preoperative baseline. Patients without preoperative baseline data, > 3 missing days or any missing days prior to reaching baseline were excluded. RESULTS: One-hundred-six patients underwent outpatient abdominal surgery. Twenty-two patients were excluded. Patients stratified into adult (18-64 years, 44 patients, 52%) and geriatric (≥ 65 years, 40 patients, 48%) cohorts. Geriatric patients were less likely to meet their preoperative baseline by postoperative day 7, 35% vs 61%, p = 0.016. Adult patients who failed to meet their preoperative baseline in first postoperative week had higher ED utilization; 4 (24%) vs 1 (4%), p = 0.04. Geriatric patients who failed to meet their baseline trended toward increased ED utilization; 5 (19%) vs. 1 (7%), p = 0.31. CONCLUSION: Patients aged < 65 who fail to return to their preoperative daily step count within one week of outpatient abdominal surgery are 6× more likely to be seen in the ED. Postoperative ambulation may be able to predict ED utilization and recovery after outpatient surgery.

BACKGROUND: Telehealth utilization rapidly increased following the pandemic. However, it is not widely used in the Veteran surgical population. We sought to evaluate postoperative telehealth in patients undergoing general surgery. METHODS: Retrospective review of Veterans undergoing general surgery at a level 1A VA Medical Center from June 2019 to September 2021. Exclusions were concomitant procedure(s), discharge with drains or non-absorbable sutures/staples, complication prior to discharge or pathology positive for malignancy. RESULTS: 1075 patients underwent qualifying procedures, 124 (12 â%) were excluded and 162 (17 â%) did not have follow-up. 443 (56 â%) patients followed-up in-person (56 â%) vs 346 (44 â%) via telehealth. Telehealth patients had a lower rate of complications, 6 â% vs 12 â%, p â= â0.013. There were no significant differences in ED visits, 30-day readmission, postoperative procedures or missed adverse events. CONCLUSION: Telehealth follow-up after general surgical procedures is safe and effective. Postoperative telehealth care should be considered after low-risk general surgery procedures.

The sequencing of information in media can influence processing of content via mechanisms like framing, mood management, and emotion regulation. This study examined three kinds of media sequences on smartphones: (1) balancing positive and negative emotional content; (2) balancing emotional content with informational content; and (3) balancing time spent on and off the media device. Actual media use was measured in natural settings using the Screenomics framework which gathers screenshots from smartphones every 5 s when devices are on. Time-series analyses of 223,531 smartphone sessions recorded from 94 participants showed that emotionally positive content was more likely to follow negative content, and that emotionally negative content was more likely to follow positive content; emotional content was more likely to follow informational content, and informational content was more likely to follow emotional content; and longer smartphone sessions were more likely to follow longer periods of non-use.
RESUMO
OBJECTIVE: To examine changes in leukocyte telomere length (LTL) during and after a behavioural weight control program for children with obesity. METHODS: We measured LTL among a cohort of 158 children 8-12 years of age with a body mass index greater than or equal to the 95th percentile for age and sex. Children were 55% female, 29% white, 52% Latinx, 8% Asian and 11% Pacific Islander, other or multiethnic. All children participated in a 6-month, family-based, group behavioural weight control program and were assessed before treatment, after treatment and 1 year after the end of treatment. To test the sample population slope of LTL over the intervention and maintenance time periods, we fit spline mixed-effect regression models. RESULTS: LTL increased an average of 0.09 T/S units per year (95% confidence interval [CI] 0.04 to 0.13; p = 0.0001) during the weight control program intervention period, followed by an average decline of -0.05 T/S units per year (95% CI -0.08 to -0.03; p < 0.0001) during the 1 year of follow-up after the completion of the intervention. Among 26 social, psychological, behavioural and physiological factors we examined, we did not find any predictors of these changes. CONCLUSIONS: LTL increased in response to a behavioural weight control program among children with obesity, suggesting an impact on biological health and cellular aging from participation in a behavioural weight control intervention. LTL may be a useful biomarker for assessing changes in response to behavioural interventions.

Changing what foods we eat could reduce environmental harms and improve human health, but sweeping dietary change is challenging. We used dietary intake data from a nationally representative sample of 7,753 US children and adults to identify simple, actionable dietary substitutions from higher- to lower-carbon foods (for example, substituting chicken for beef in mixed dishes such as burritos, but making no other changes to the diet). We simulated the potential impact of these substitutions on dietary carbon emissions and dietary quality. If all consumers who ate the high-carbon foods instead consumed a lower-carbon substitute, the total dietary carbon footprint in the United States would be reduced by more than 35%. Moreover, if adopted, these substitutions would improve consumers' overall dietary quality by 4-10%, with benefits projected for all age, gender, and racial and ethnic groups. These results suggest that a 'small changes' approach could be a valuable starting point for addressing diet's impact on climate and health.

Up to now, there was no way to observe and track the affective impacts of the massive amount of complex visual stimuli that people encounter "in the wild" during their many hours of digital life. In this paper, we propose and illustrate how recent advances in AI-trained ensembles of deep neural networks-can be deployed on new data streams that are long sequences of screenshots of study participants' smartphones obtained unobtrusively during everyday life. We obtained affective valence and arousal ratings of hundreds of images drawn from existing picture repositories often used in psychological studies, and a new screenshot repository chronicling individuals' everyday digital life from both N = 832 adults and an affect computation model (Parry & Vuong, 2021). Results and analysis suggest that (a) our sample rates images similarly to other samples used in psychological studies, (b) the affect computation model is able to assign valence and arousal ratings similarly to humans, and (c) the resulting computational pipeline can be deployed at scale to obtain detailed maps of the affective space individuals travel through on their smartphones. Leveraging innovative methods for tracking the emotional content individuals encounter on their smartphones, we open the possibility for large-scale studies of how the affective dynamics of everyday digital life shape individuals' moment-to-moment experiences and well-being.

RESUMO
BACKGROUND: Stray energy transfer from monopolar instruments during laparoscopic surgery is a recognized cause of potentially catastrophic complications. There are limited data on stray energy injuries in robotic surgery. We sought to characterize stray energy injury in the form of superficial burns to the skin surrounding laparoscopic and robotic trocar sites. Our hypothesis was that stray energy burns will occur at all laparoscopic and robotic port sites. METHODS: We conducted a prospective, randomized controlled trial of patients undergoing elective unilateral inguinal hernia repair at a VAMC over a 4-year period. Surgery was performed via transabdominal preperitoneal approach either laparoscopic-assisted (TAPP) or robotic-assisted (rTAPP). A monopolar scissor was used to deliver energy at 30W coagulation for all cases. At completion of the procedure, skin biopsies were taken from all the port sites. A picro-Sirius red stain was utilized to identify thermal injury by a blinded pathologist. RESULTS: Over half (54%, 59/108) of all samples demonstrated thermal injury to the skin. In the laparoscopic group, 49% (25/51) samples showed thermal injury vs. 60% (34/57) in the robotic group (p = 0.548). The camera port was the most frequently involved with 68% (13/19) rTAPP samples showing injury vs. 47% (8/17) in the TAPP group (p = 0.503). There was no difference in the rate of injury at the working port site (rTAPP 53%, 10/19 vs. TAPP 47%, 8/17; p = 0.991) or the assistant port site (rTAPP 58%, 11/19 vs. TAPP 53%, 9/17; p = 0.873). CONCLUSIONS: Stray energy causes thermal injury to the skin at port sites in the majority robotic laparoscopic TAPP inguinal hernia repairs. There is no difference in stray energy transfer between the laparoscopic and robotic platform. This is the first study to confirm in-vivo transfer of stray energy during robotic surgical procedures. More study is needed to determine the clinical significance of these thermal injuries.

Advances in ability to comprehensively record individuals' digital lives and in AI modeling of those data facilitate new possibilities for describing, predicting, and generating a wide variety of behavioral processes. In this paper, we consider these advances from a person-specific perspective, including whether the pervasive concerns about generalizability of results might be productively reframed with respect to transferability of models, and how self-supervision and new deep neural network architectures that facilitate transfer learning can be applied in a person-specific way to the super-intensive longitudinal data arriving in the Human Screenome Project. In developing the possibilities, we suggest Molenaar add a statement to the person-specific Manifesto - "In short, the concerns about generalizability commonly leveled at the person-specific paradigm are unfounded and can be fully and completely replaced with discussion and demonstrations of transferability."
RESUMO
BACKGROUND: The American College of Surgeons (ACS) Coalition for Quality in Geriatric Surgery (CQGS) identified standards of surgical care for the growing, vulnerable population of aging adults in the US. The aims of this study were to determine implementation feasibility for 30 selected standards, identify barriers and best practices in their implementation, and further refine these geriatric standards and verification process. STUDY DESIGN: The CQGS requested participation from hospitals involved in the ACS NSQIP Geriatric Surgery Pilot Project, previous CQGS feasibility analyses, and hospitals affiliated with a core development team member. Thirty standards were selected for implementation. After implementation, site visits were conducted, and postvisit surveys were distributed. RESULTS: Eight hospitals were chosen to participate. Program management (55%), immediate preoperative and intraoperative clinical care (62.5%), and postoperative clinical care (58%) had the highest mean percentage of "fully compliant" standards. Goals and decision-making (30%), preoperative optimization (28%), and transitions of care (12.5%) had the lowest mean percentage of fully compliant standards. Best practices and barriers to implementation were identified across 13 of the 30 standards. More than 80% of the institutions reported that participation changed the surgical care provided for older adults. CONCLUSIONS: This study represents the first national implementation assessment undertaken by the ACS for one of its quality programs. The CQGS pilot testing was able to demonstrate implementation feasibility for 30 standards, identify challenges and best practices, and further inform dissemination of the ACS Geriatric Surgery Verification Program.

Although media production is a critical concept in communication theory, we know surprisingly little about the timing, content, and context of individuals' production behavior. Intensive observation and analysis of 94 American adults' smartphone use over 1 week showed that although time spent in producing content was on average only about 6 percent of the amount of time spent on smartphones, the production content was more purposeful, expressive, articulate, condensed, confident, personal, and emotionally charged than consumption content. Analysis of the temporal dynamics of production suggests that the content consumed in the minute before individuals' production began to resemble the subsequently produced content. Other results suggest that content production on smartphones was fragmented, idiosyncratic, and purposeful, highlighting the impact of individuals' quick interactions with media, and the need to develop user-centric theories about how, when, and why individuals produce digital content.

INTRODUCTION: Telehealth has been increasingly utilized with a renewed interest by surgical specialties given the COIVD-19 pandemic. Limited data exists evaluating the safety of routine postoperative telehealth follow-up in patients undergoing inguinal hernia repair, especially those who present urgent/emergently. Our study sought to evaluate the safety and efficacy of postoperative telehealth follow-up in veterans undergoing inguinal hernia repair. METHODS: Retrospective review of all Veterans who underwent inguinal hernia repair at a tertiary Veterans Affairs Medical Center over a 2-year period (9/2019-9/2021). Outcome measures included postoperative complications, emergency department (ED) utilization, 30-day readmission, and missed adverse events (ED utilization or readmission occurring after routine postoperative follow-up). Patients undergoing additional procedure(s) requiring intraoperative drains and/or nonabsorbable sutures were excluded. RESULTS: Of 338 patients who underwent qualifying procedures, 156 (50.6%) were followed-up by telehealth and 152 (49.4%) followed-up in-person. There were no differences in age, sex, BMI, race, urgency, laterality nor admission status. Patients with higher American Society of Anesthesiologists (ASA) classification [ASA class III 92 (60.5%) versus class II 48 (31.6%), P = 0.019] and open repair [93 (61.2%) versus 67 (42.9%), P = 0.003] were more likely to follow-up in-person. There was no difference in complications, [telehealth 13 (8.3%) versus 20 (13.2%), P = 0.17], ED visits, [telehealth 15 (10%) versus 18 (12%), P = 0.53], 30-day readmission [telehealth 3 (2%) versus 0 (0%), P = 0.09], nor missed adverse events [telehealth 6 (33.3%) versus 5 (27.8%), P = 0.72]. CONCLUSIONS: There were no differences in postoperative complications, ED utilization, 30-day readmission, or missed adverse events for those who followed-up in person versus telehealth after elective or urgent/emergent inguinal hernia repair. Veterans with a higher ASA class and who underwent open repair were more likely to be seen in person. Telehealth follow-up after inguinal hernia repair is safe and effective.

INTRODUCTION: Stray energy from surgical energy instruments can cause unintended thermal injuries. There are no published data regarding electrosurgical generators and their influence on stray energy transfer during robotic surgery. There are two approved generators for the DaVinci Xi robotic platform: a constant-voltage regulating generator (cVRG) and a constant-power regulating generator (cPRG). The purpose of this study was to quantify and compare stray energy transfer in the robotic Xi platform using a cVRG versus a cPRG. METHODS: An ex vivo bovine model was used to simulate a standard multiport robotic surgery. The DaVinci Xi (Intuitive Surgical, Sunnyvale, CA) robotic platform was attached to a trainer box using robotic ports. A 5 s, open-air activation of the monopolar scissors was done with commonly used electrosurgical settings using a cPRG (ForceTriad, Covidien-Medtronic, Boulder, CO) or cVRG (ERBE VIO 300 dV 2.0, ERBE USA, Marietta, GA). Stray energy transfer was quantified as the change in tissue temperature (°C) nearest the tip of the assistance grasper (which was not in direct contact with the active monopolar scissors). RESULTS: Stray energy transfer occurred with both generators. Utilizing common, comparable settings for standard coagulation, significantly less stray energy was transferred with the cVRG versus cPRG (4.4 ± 1.6 °C vs. 41.1 ± 13.0 °C, p < 0.001). Similarly, less stray energy was transferred using cut modes with the cVRG compared to the cPRG (5.61 ± 1.79 °C vs. 33.9 ± 18.4 °C, p < 0.001). CONCLUSION: Stray energy transfer increases tissue temperatures more than 45C in the DaVinci Xi robotic platform. Low voltage modalities, such as cut or blend; as well as a cVRG generator, significantly reduces stray energy. Robotic surgeons can minimize the risk of stray energy injuries by using these low risk modes and/or generator.

This prospective, longitudinal study examined associations between whether and when children first acquire a mobile phone and their adjustment measures, among low-income Latinx children. Children (N = 263; 55% female; baseline Mage = 9.5) and their parents were assessed annually for 5 years from 2012. Children first acquired a mobile phone at a mean (SD) age of 11.62 (1.41) years. Pre-registered multilevel models tested associations linking phone ownership, phone acquisition age, and the interaction between ownership and acquisition age to levels and changing trends of depressive symptoms, school grades, and reported and objectively assessed sleep. Results showed no statistically significant associations, controlling the False Discovery Rate. Findings suggest an absence of meaningful links from mobile phone ownership and acquisition age to child adjustment.

BACKGROUND: The COVID-19 pandemic has brought many challenges including barriers to delivering high-quality surgical care and follow-up while minimizing the risk of infection. Telehealth has been increasingly utilized for post-operative visits, yet little data exists to guide surgeons in its use. We sought to determine safety and efficacy of telehealth follow-up in patients undergoing cholecystectomy during the global pandemic at a VA Medical Center (VAMC). METHODS: This was a retrospective review of patients undergoing cholecystectomy at a level 1A VAMC over a 2-year period from August 2019 to August 2021. Baseline demographics, post-operative complications, readmissions, emergency department (ED) visits and need for additional procedures were reviewed. Patients who experienced a complication prior to discharge, underwent a concomitant procedure, had non-absorbable skin closure, had new diagnosis of malignancy or were discharged home with drain(s) were ineligible for telehealth follow-up and excluded. RESULTS: Over the study period, 179 patients underwent cholecystectomy; 30 (17%) were excluded as above. 20 (13%) missed their follow-up, 52 (35%) were seen via telehealth and 77 (52%) followed-up in person. There was no difference between the two groups regarding baseline demographics or intra-operative variables. There was no significant difference in post-operative complications [4 (8%) vs 6 (8%), p > 0.99], ED utilization [5 (10%) vs 7 (9%), p = 0.78], 30-day readmission [3 (6%) vs 6 (8%), p = 0.74] or need for additional procedures [2 (4%) vs 4 (5%), p = 0.41] between telehealth and in-person follow-up. CONCLUSION: Telehealth follow-up after cholecystectomy is safe and effective in Veterans. There were no differences in outcomes between patients that followed up in-person vs those that were seen via phone or video. Routine telehealth follow-up after uncomplicated cholecystectomy should be considered for all patients.
