Abstract
Important elements of the preoperative assessment that should be addressed for the older adult population include frailty, comorbidities, nutritional status, cognition, and medications. Frailty has emerged as a plausible predictor of adverse outcomes after surgery. It is present in older patients and is characterized by multisystem physiologic decline, increased vulnerability to stressors, and adverse clinical outcomes. Preoperative preparation may include a prehabilitation program, which aims to address nutritional insufficiencies, modify chronic polypharmacy, and enhance physical and respiratory conditions prior to hospital admission. Special considerations are taken for particularly high-risk patients, where the approach to prehabilitation can address specific, individual risk factors. Identifying patients who are nutritionally deficient allows practitioners to intervene preoperatively to optimize their nutritional status, and different strategies are available, such as immunonutrition. Previous studies have shown an association between increased frailty and the risk of postoperative complications, morbidity, hospital length of stay, and 30-day and long-term mortality following general surgical procedures. Evidence from numerous studies suggests a potential benefit of including a standard assessment of frailty as part of the preoperative workup of older adult patients. Studies addressing validated frailty assessments and the quantification of their predictive capabilities in various surgeries are warranted.

Preoperative Management of Pheochromocytoma and Paraganglioma.
Fang, F, Ding, L, He, Q, Liu, M
Frontiers in endocrinology. 2020;:586795
Abstract
Pheochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumors, characterized by excessive release of catecholamines (CAs), and manifested as the classic triad of headaches, palpitations, profuse sweating, and a variety of other signs and symptoms. The diagnosis of PPGL requires both evidence of excessive release of CAs and anatomical localization of CA-secreting tumor. Surgery is the mainstay of treatment for all patients with PPGL unless contraindicated. However, without proper preparation, the release of excessive CAs, especially during surgery, can result in lethal cardiovascular complications. Herein, we briefly reviewed the pathogenesis of this disease, discussed the current approaches and evidence available for preoperative management, summarizing the results of the latest studies which compared the efficacies of preoperative management with or without α adrenergic-receptor antagonists, aiming to facilitate better understanding of the preoperative management of PPGL for the physicians.

Abstract
The aims of this pilot study are to evaluate the feasibility, safety, and effectiveness of conducting an enhanced nutritional support pathway including extended preoperative nutritional support and one month home enteral nutrition (HEN) for patients who underwent enhanced recovery after esophagectomy. We implemented extended preoperative nutritional support and one month HEN after discharge for patients randomized into an enhanced nutrition group and implemented standard nutritional support for patients randomized into a conventional nutrition group. Except the nutritional support program, both group patients underwent the same standardized enhanced recovery after surgery programs of esophagectomy based on published guidelines. Patients were assessed at preoperative day, postoperative day 7 (POD7), and POD30 for perioperative outcomes and nutritional status. To facilitate the determination of an effect size for subsequent appropriately powered randomized clinical trials and assess the effectiveness, the primary outcome we chose was the weight change before and after esophagectomy. Other outcomes including body mass index (BMI), lean body mass (LBM), appendicular skeletal muscle mass index (ASMI), nutrition-related complications, and quality of life (QoL) were also analyzed. The intention-to-treat analysis of the 50 randomized patients showed that there was no significant difference in baseline characteristics. The weight (-2.03 ± 2.28 kg vs. -4.05 ± 3.13 kg, P = 0.012), BMI (-0.73 ± 0.79 kg/m2 vs. -1.48 ± 1.11 kg/m2, P = 0.008), and ASMI (-1.10 ± 0.37 kg/m2 vs. -1.60 ± 0.66 kg/m2, P = 0.010) loss of patients in the enhanced nutrition group were obviously decreased compared to the conventional nutrition group at POD30. In particular, LBM (48.90 ± 9.69 kg vs. 41.96 ± 9.37 kg, p = 0.031) and ASMI (7.56 ± 1.07 kg/m2 vs. 6.50 ± 0.97 kg/m2, P = 0.003) in the enhanced nutrition group were significantly higher compared to the conventional nutrition group at POD30, despite no significant change between pre- and postoperation. In addition, European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 scores revealed that enhanced nutritional support improved the QoL of patients in physical function (75.13 ± 9.72 vs. 68.33 ± 7.68, P = 0.009) and fatigue symptom (42.27 ± 9.93 vs. 49.07 ± 11.33, P = 0.028) compared to conventional nutritional support. This pilot study demonstrated that an enhanced nutritional support pathway including extended preoperative nutritional support and HEN was feasible, safe, and might be beneficial to patients who underwent enhanced recovery after esophagectomy. An appropriately powered trial is warranted to confirm the efficacy of this approach.

Abstract
INTRODUCTION DCL-101, a novel Pill Prep, is compositionally identical to standard 4L polyethylene glycol-electrolyte solution (PEG-ELS) and delivers the salt encapsulated, with PEG 3350 coadministered as a taste-free oral solution. The aim of this study was to compare the safety, taste, and tolerability of DCL-101 with 4L PEG-ELS in outpatients preparing for colonoscopy, with a secondary objective to assess efficacy. METHODS This was a multicenter, randomized, investigator-blinded, phase 2 clinical trial of 45 adult patients undergoing outpatient colonoscopy. Patients were randomized 2:1 to either DCL-101 (3L in cohort 1; 4L in cohort 2) or 4L PEG-ELS, each administered with split dosing. Safety was assessed over 3 post-treatment clinic visits. Tolerability was measured using the Lawrance Bowel-Preparation Tolerability Questionnaire and the Mayo Clinic Bowel Prep Tolerability Questionnaire. Efficacy was determined by expert central readers, blinded to treatment, using the Ottawa Bowel Preparation Quality Scale, Boston Bowel Preparation Scale, and Aronchick scale. RESULTS Both DCL-101 doses had superior taste and tolerability relative to 4L PEG-ELS. All adverse events were grade 1 with no significant differences in adverse events among the 3 regimens. There were no significant differences in efficacy among the 3 treatments as defined by the centrally read Ottawa Bowel Preparation Quality Scale, Boston Bowel Preparation Scale, or Aronchick scores. There were no inadequate preps as judged by the site endoscopist. DISCUSSION DCL-101 Pill Prep is a novel strategy that vastly improves the taste and tolerability of PEG-ELS solutions with safety and efficacy comparable with split-dose 4L PEG-ELS solutions.

Abstract
Surgical site infection is associated with prolonged hospital stay and increased morbidity, mortality and healthcare costs, as well as a poorer patient quality of life. Many hospitals have adopted scientifically-validated guidelines for the prevention of surgical site infection. Most of these protocols have resulted in improved postoperative results. The Surgical Infection Division of the Spanish Association of Surgery conducted a critical review of the scientific evidence and the most recent international guidelines in order to select measures with the highest degree of evidence to be applied in Spanish surgical services. The best measures are: no removal or clipping of hair from the surgical field, skin decontamination with alcohol solutions, adequate systemic antibiotic prophylaxis (administration within 30-60minutes before the incision in a single preoperative dose; intraoperative re-dosing when indicated), maintenance of normothermia and perioperative maintenance of glucose levels.

Clinical nutrition (Edinburgh, Scotland). 2020;(8):2455-2462
Abstract
OBJECTIVE Infants with congenital heart disease (CHD) often experience growth failure prior to surgery, which is associated with increased paediatric-intensive-care unit length of stay (PICU-LOS) and post-operative complications. This study assessed the impact of a pre-operative, consensus-based nutritional pathway (including support from a multi-disciplinary team) on growth and clinical outcome. DESIGN Single-centre prospective pilot study. SETTING Tertiary paediatric cardiology surgical centre. PATIENTS Infants with CHD. INTERVENTION Infants with CHD were followed for up to 4-months-of-age before cardiac surgery and then to 12-months-of-age following the implementation of the consensus-based nutritional-pathway (Intervention group: November 2017-August 2018), with outcomes compared to a historic control group. The nutrition pathway involved a dietitian contacting parents of infants with the highest risk of growth failure weekly; reviewing weight gain and providing feeding support. MAIN OUTCOME MEASURE Growth (weight-for-age, WAZ, and height-for-age-z-score, HAZ) at 4 and 12 months-of-age. RESULTS 44 infants in the intervention group were compared to 38 in the control group. Median (inter quartile range) change in WAZ from birth to 4 months-of-age (-0.9 (-1.5, 0.7)) and from birth to 12 months-of-age (-0.09 (-1.3, 1.1)) in the intervention group compared to the control group (-1.5 (-2.0, -0.4) (p = 0.04)) at 4 months-of age and at 12 months-of-age (-0.4 (1.9, 0.2) (p = 0.03)). HAZ at 4 months-of-age was -0.7 (-1.4, -0.1) vs. -1.0 (-1.9, -0.3) (p = 0.6) in the intervention and control groups respectively, and at 12 months-of-age HAZ was -0.7 (-1.9, -0.07) in the intervention group vs.-1.6 (-2.6, -0.4) in the control group (p = 0.04). Duration of PICU-LOS was 8.2 ± 11.6 days intervention vs. 18.3 ± 24.0 days control (p = 0.006). CONCLUSION Overall weight was well maintained and growth improved in infants who followed the pre-operative nutritional-pathway. The duration of PICU-LOS was significantly lower in the intervention group, which may be due to improved nutritional status, although this requires further investigation.

Prehabilitation: metabolic considerations.
Chabot, K, Gillis, C, Carli, F
Current opinion in clinical nutrition and metabolic care. 2020;(4):271-276
Abstract
PURPOSE OF REVIEW The major components of ERAS attenuate the inflammatory response and modulate metabolism in direction of sparing body protein and preserving function. However, these perioperative interventions might have limited effectiveness on postoperative outcomes if preoperative risk factors are not addressed and optimized. RECENT FINDINGS The preoperative metabolic perturbations characterized by insulin resistance and sarcopenia might predispose patients to a higher degree of postoperative catabolism. High-risk populations for such metabolic disturbances include elderly and frail patients, and patients with metabolic syndrome. Research on the effect of prehabilitation on perioperative metabolism is limited, but recent findings suggest that interventions designed to improve insulin sensitivity prior to surgery might represent a promising therapeutic target to minimize surgical complications. SUMMARY The present paper will discuss the metabolic implications of modulating preoperative risk factors with elements of multimodal prehabilitation, such as exercise training and nutrition.

Abstract
BACKGROUND AND OBJECTIVE To determine the safety and efficacy of intravitreal aflibercept injection (IAI) in patients with diabetic retinopathy (DR) in the prevention of macular edema (ME) following cataract surgery. PATIENTS AND METHODS This phase 2, prospective, interventional, single-masked, randomized trial at a single academic center included 30 patients who were 18 years of age or older with nonproliferative DR and undergoing cataract surgery with phacoemulsification. Patients received 2 mg intravitreal aflibercept (0.05 mL) or sham injection during cataract surgery. Main outcome measures included treatment adverse events (AEs), best-corrected visual acuity (BCVA), and incidence of ME (defined as presence of cystoid abnormalities as detected by optical coherence tomography at any follow-up visit), a 30% or greater increase from preoperative baseline in central subfield macular thickness, or a BCVA decrease of more than 5 ETDRS letters from Day 7 due to retinal thickening. RESULTS There were similar incidences of AEs between the two groups and no clinically serious ocular AEs in either group. The IAI group had fewer ME events at Day 14 (13% vs. 53%; P = .022), but there was no significant difference in ME events at Day 30 (27% vs. 60%; P = .057), Day 60 (27% vs. 60%; P = .057), or Day 90 (40% vs. 67%; P = .161). Compared to the study group, the control group had a significantly greater increase in central subfield thickness (CST) at Day 30 (50.05 μm vs. 7.95 μm; P = .040) and Day 60 (56.45 μm vs. 3.02 μm; P = .010). However, the difference in CST between groups was no longer significant at Day 90 (50.31 μm vs. 18.48 μm; P = .12). There were no significant differences in BCVA gains between the IAI and sham group at the end of the follow-up period (Day 90, ETDRS letters: 9.88 vs. 8.52; P = .66). CONCLUSIONS Use of IAI in patients with DR for prevention of ME following cataract surgery showed no significant AEs. Although there were significant differences in ME incidence and retinal thickness at periods of time, there was no clinically meaningful benefit in terms of VA. Further larger trials are needed to validate these findings. [Ophthalmic Surg Lasers Imaging Retina. 2020;51:170-178.].

David, LA, Sijercic, I, Cassin, SE
Obesity reviews : an official journal of the International Association for the Study of Obesity. 2020;(4):e12926
Abstract
Psychosocial interventions are increasingly being utilized to help patients prepare for, and adjust to changes following, bariatric surgery in order to optimize psychosocial adjustment and weight loss. The current systematic review examined the impact of preoperative and post-operative psychosocial interventions with a behavioural and/or cognitive focus on weight, dietary behaviours, eating pathology, lifestyle behaviours, and psychological functioning. A PsycINFO and Medline search of publications was conducted in March 2019. Two authors assessed retrieved titles and abstracts to determine topic relevance and rated the quality of included studies using a validated checklist. Forty-four articles (representing 36 studies) met the study inclusion criteria. The current evidence is strongest for the impact of psychosocial interventions, particularly cognitive behavioural therapy, on eating behaviours (eg, binge eating and emotional eating) and psychological functioning (eg, quality of life, depression, and anxiety). The evidence for the impact of psychosocial interventions on weight loss, dietary behaviours (eg, dietary intake), and lifestyle behaviours (eg, physical activity) is relatively weak and mixed. Psychosocial interventions can improve eating pathology and psychosocial functioning among bariatric patients, and the optimal time to initiate treatment appears to be early in the post-operative period before significant problematic eating behaviours and weight regain occur.
