Convalescing: Reflections in a Post-pandemic World.

The COVID-19 pandemic brought with it many hardships to the world as a whole. Mass infection and casualties due to disease state were rampant, which affected many families. Lockdown drove up the incidence of depression and isolated people from their loved ones. The toll on the general population was high, as was the toll on the medical community, a subset of the general population. It was a time of death and devastation, with supply chain issues creating personal protective equipment shortages and staffing being affected by illness, fear, age, and expertise. Despite the constraints, many places were able to rally staff together to provide adequate staffing for healthcare delivery purposes to serve our communities. Cross-specialty collaboration in the outpatient and inpatient setting as well as the use of technology aided our service to our community to help persevere through the many surges of the pandemic and come out with lessons learned as well as reflections.

Preoperative Management of Cardiovascular Medications: A Society for Perioperative Assessment and Quality Improvement (SPAQI) Consensus Statement.

Cardiovascular conditions such as hypertension, arrhythmias, and heart failure are common in patients undergoing anesthesia for surgical or other procedures. Numerous guidelines from various specialty societies offer variable recommendations for the perioperative management of these medications. The Society for Perioperative Assessment and Quality Improvement identified a need to provide multidisciplinary evidence-based recommendations for preoperative medication management. The society convened a group of 13 members with expertise in perioperative medicine and training in anesthesiology or internal medicine. The aim of this consensus effort is to provide perioperative clinicians with guidance on the management of cardiovascular medications commonly encountered during the preoperative evaluation. We used a modified Delphi process to establish consensus. Twenty-one classes of medications were identified: α-adrenergic receptor antagonists, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, angiotensin receptor-neprilysin inhibitors, ß-adrenoceptor blockers, calcium-channel blockers, centrally acting sympatholytic medications, direct-acting vasodilators, loop diuretics, thiazide diuretics, potassium-sparing diuretics, endothelin receptor antagonists, cardiac glycosides, nitrodilators, phosphodiesterase-5 inhibitors, class III antiarrhythmic agents, potassium-channel openers, renin inhibitors, class I antiarrhythmic agents, sodium-channel blockers, and sodium glucose cotransportor-2 inhibitors. We provide recommendations for the management of these medications preoperatively.

Sunitinib-associated hyperammonemic encephalopathy.

Sunitinib-associated hyperammonemic encephalopathy has not been previously reported in the emergency medicine literature. As newer treatments for cancer become more widespread and patients live longer, the emergence of previously unreported or rare adverse effects is expected to increase. Here we report the case of a 71-year-old woman with infiltrating ductal carcinoma of the breast with metastasis to the liver who developed hyperammonemic encephalopathy after taking sunitinib for 12 days. She presented to the emergency department (ED) with confusion and the initial workup revealed an elevated ammonia level (202 µmol/L; reference range, 11-51 µmol/L) without evidence of cirrhosis or portal hypertension. The patient was started on lactulose and admitted to the hospital, where her ammonia levels and mental status waxed and waned throughout her 12-day hospitalization. Further workup with magnetic resonance imaging and an electroencephalogram were negative. After 12 days, her ammonia level normalized and she was discharged without re-initiating Sunitinib. The patient was followed for three months post hospitalization without recurrence of symptoms. Patients on sunitinib should have their ammonia levels checked when presenting to the ED with altered mentation for early identification of hyperammonemic encephalopathy and its potential complications, such as seizures, brain edema, and death. Emergent management in the ED should include initiation of lactulose and consultation with the gastroenterology team.

Home-Based Exercise Prehabilitation During Preoperative Treatment for Pancreatic Cancer Is Associated With Improvement in Physical Function and Quality of Life.

Purpose: To investigate relationships among physical activity, changes in physical function, and health-related quality of life (HRQOL) among patients with pancreatic adenocarcinoma enrolled in a home-based exercise prehabilitation program. Methods: Patients with resectable pancreatic adenocarcinoma receiving preoperative chemotherapy and/or chemoradiation were enrolled on this prospective, single-arm trial and were advised to perform ≥60 minutes each of moderate-intensity aerobic exercise and strengthening exercise weekly. Activity was measured via self-report and accelerometers, including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary activity (SA). Physical function measures at baseline and restaging follow-up included 6-minute walk test (6MWT), 5 times sit-to-stand (5×STS), handgrip strength (HGS), 3-m walk for gait speed (GS), and the PROMIS Physical Function Short Form. HRQOL was measured via the FACT-Hep questionnaire. Results: Fifty participants with mean age 66 years (standard deviation = 8 years) were enrolled. The 6MWT, 5×STS, and GS significantly improved from baseline to restaging follow-up (P=.001, P=.049, and P=.009, respectively). Increases in self-reported aerobic exercise, weekly MVPA, and LPA were associated with improvement in 6MWT (ß=.19, P=.048; ß=.18, P=.03; and ß=.08, P=.03, respectively) and self-reported physical functioning (ß=.02, P=.03; ß=.03, P=.005; and ß=.01, P=.02, respectively). Increased weekly LPA was associated with increased HRQOL (ß=.03, P=.02). Increased SA was associated with decreased HRQOL (ß=-.02,P=.01). Conclusions: Patients with potentially resectable pancreatic cancer exhibit meaningful improvement in physical function with prehabilitation; physical activity was associated with improved physical function and HRQOL. These data highlight the importance of physical activity during treatment for pancreatic cancer.

Supports and Barriers to Home-Based Physical Activity During Preoperative Treatment of Pancreatic Cancer: A Mixed-Methods Study.

BACKGROUND: Physical activity and exercise appear to benefit patients receiving preoperative treatment for cancer. Supports and barriers must be considered to increase compliance with home-based exercise prescriptions in this setting. Such influences have not been previously examined. METHODS: The authors used quantitative and qualitative methods to examine potential physical activity influences among patients who were prescribed home-based aerobic and strengthening exercises concurrent with preoperative chemotherapy or chemoradiation for pancreatic cancer. Physical activity was measured using exercise logs and accelerometers. Social support for exercise and perceived neighborhood walkability were measured using validated surveys. Relationships between influences and physical activity were evaluated using linear regression analyses and qualitative interviews. RESULTS: Fifty patients received treatment for a mean of 16 (9) weeks prior to planned surgical resection. Social support from friends and neighborhood esthetics were positively associated with physical activity (P < .05). In interviews, patients confirmed the importance of these influences and cited encouragement from health care providers and desire to complete and recover from treatment as additional motivators. CONCLUSIONS: Interpersonal and environmental motivators of exercise and physical activity must be considered in the design of future home-based exercise interventions designed for patients receiving preoperative therapy for cancer.

Prospective pilot trial with combination of propranolol with chemotherapy in patients with epithelial ovarian cancer and evaluation on circulating immune cell gene expression.

OBJECTIVE: To determine the feasibility of pharmacologic beta-adrenergic blockade in women with newly diagnosed stage II-IV epithelial ovarian cancer (EOC) throughout primary treatment. METHODS: Patients initiated propranolol prior to beginning chemotherapy or surgery. Feasibility was assessed as proportion able to complete 6 chemotherapy cycles while on adrenergic suppression. Descriptive statistics summarized surveys, and paired changes were analyzed using signed rank tests. Random-intercept Tobit models examined immune response. RESULTS: Median age was 59.9; 88.5% were stage IIIC/IV; and 38.5% underwent primary debulking. Thirty-two patients were enrolled; 3 excluded because they never took propranolol; an additional 3 didn't meet inclusion criteria, leaving 26 evaluable. Eighteen of 26 (69%), 90% credible interval (CI) of 53-81%, completed 6 chemotherapy cycles plus propranolol (an 82% posterior probability that the true proportion of success is ≥60%). Among the 23 patients with baseline and six month follow up data, overall QOL, anxiety, and depression improved (P < 0.05) and leukocyte expression of pro-inflammatory genes declined (P = 0.03) after completion of therapy. Decrease from baseline of serum IL-6 and IL-8 preceded response to chemotherapy (P < 0.0014). Change from baseline IL-10 preceded complete response. CONCLUSION: Use of propranolol during primary treatment of EOC is feasible and treatment resulted in decrease in markers of adrenergic stress response. In combination with chemotherapy, propranolol potentially results in improved QOL over baseline.

Physical activity and exercise during preoperative pancreatic cancer treatment.

PURPOSE: Guidelines recommend exercise to cancer survivors, but limited data exists regarding exercise among patients undergoing preoperative cancer treatment. We examined differences in weekly self-reported exercise and accelerometer-measured physical activity among participants in a home-based exercise program administered during preoperative treatment for pancreatic cancer. METHODS: Participants were encouraged to perform at least 60 min/week of moderate-intensity aerobic exercise and at least 60 min/week of full-body strengthening exercises concurrent with chemotherapy, chemoradiation therapy or both sequentially and received resistance equipment, program instruction, and biweekly follow-up calls to encourage adherence. Self-reported aerobic and strengthening exercise minutes were measured using daily logs, and physical activity was measured objectively using accelerometers. RESULTS: Fifty participants (48% female, mean age 66 ± 8 years) participated for an average of 16 ± 9 preoperative weeks. Participants reported overall means of 126 ± 83 weekly minutes of aerobic exercise and 39 ± 33 weekly minutes of strengthening exercise in daily logs. Participants performed 158.7 ± 146.7 weekly minutes of accelerometer-measured moderate-to-vigorous physical activity. There were no significant differences in exercise or physical activity between treatment phases. CONCLUSIONS: These findings suggest that it is feasible to target the entire preoperative course for exercise prescription. Although participants exceeded aerobic exercise recommendations on average, we observed low strengthening exercise adherence and wide variability in self-reported exercise and accelerometer physical activity variables. These findings suggest that additional support, including program adaptations, may be necessary to overcome barriers to exercise or improve motivation when prescribing exercise in this clinical scenario.

Effects of thiazolidinedione in patients with active bladder cancer.

OBJECTIVE: To examine the influence of perioperative thiazolidinedione (TZD) on cancer-specific outcomes in patients with diabetes mellitus (DM) undergoing radical cystectomy (RC) for urothelial carcinoma (UC). PATIENTS AND METHODS: A retrospective cohort of 173 patients with DM undergoing RC from 2005 to 2010 was identified. Of those, 53 were on TZD treatment at the time of RC, with 33 patients taking pioglitazone. Baseline clinicopathological characteristics, as well as cancer-specific survival (CSS), recurrence-free survival (RFS), and overall survival (OS) were compared between the patients on and off TZD therapy at the time of RC. In subgroup analysis, outcomes in patients specifically taking pioglitazone at the time of RC were compared to those not on a TZD. RESULTS: Baseline clinicopathological characteristics were similar between patients on and off TZD therapy at the time of RC. Overall, the median CSS rate was not reached in either group (P = 0.7). The estimated 5-year CSS was 67.8% in the non-TZD group and 66.3% in the TZD group. On multivariate analysis incorporating patient age, pathological T-staging, and adjuvant chemotherapy, TZD use was found not to be a significant predictor for CSS (hazard ratio 1.20, 95% confidence interval 0.66-2.17; P = 0.5). Additionally, RFS (P= 0.3) and OS (P = 0.2) were also similar between the two groups without adjusting for other variables. Comparison between patients taking pioglitazone vs patients not taking TZD yielded similar CSS (P = 0.2), RFS (P = 0.5), and OS (P= 0.2). CONCLUSIONS: CSS, as well as RFS and OS after RC were not compromised in patients on TZD therapy at the time of RC. Additional investigation is warranted in patients with non-muscle-invasive bladder cancer and muscle-invasive bladder cancer undergoing bladder-sparing procedures to assess the safety of using TZD in the setting of active UC.

Serum brain naturietic peptide measurements reflect fluid balance after pancreatectomy.

BACKGROUND: Overaggressive fluid resuscitation in elderly patients requiring pancreatectomy can delay recovery and increase morbidity. Despite advancements, no accurate and reproducible methods exist to evaluate effective intravascular volume status in the postoperative setting. We hypothesized that sequential measurement of currently available serum proteins will indicate fluid balance. STUDY DESIGN: Clinicopathologic (n = 44) and echocardiogram (echo) data (n = 18) were collected on patients receiving pancreatectomy or diagnostic laparoscopy (n = 5). Measured fluid balance, serum BUN, creatinine (CR), and brain natriuretic peptide (BNP) levels were recorded on postoperative days (POD) 1 to 7 (only POD1 for diagnostic laparoscopy). ANOVA and bivariate random effect models examined the correlation between BNP and BUN/CR and fluid balance. Linear mixed-effect models examined the correlation between factors associated with vascular stiffness and BNP, BUN/CR, and fluid balance. RESULTS: On POD1 after diagnostic laparoscopy, the fluid balance was positive by 3,265 mL and was accompanied by a >300-point increase in BNP (p = 0.0083). After pancreatectomy, a similar increase in BNP (250 pg/mL) and fluid balance (4,492 mL) on POD1 was observed. During the return to euvolemia, the change in serum BNP levels correlated with fluid balance changes during POD 1 to 3 (p = 0.039), and BUN/CR levels correlated with fluid balance during POD 4 to 7. Patients with risk factors associated with cardiovascular stiffness or echo evidence of poor compliance experienced higher BNP during the postoperative period. CONCLUSIONS: Fluid loading at surgery is accompanied by an increase in serum BNP, and return to a balanced fluid state after pancreatectomy is paralleled by changes in BNP and BUN/CR levels.

Preoperative evaluation of the oncology patient.

This review focuses on the unique perioperative concerns of patients with cancer undergoing surgery. Importantly, not all surgical procedures are intended as cures: some patients who have cancer also undergo surgery for noncancer issues. Also, many of these patients have undergone prior chemotherapy and/or radiation therapy that can introduce perioperative concerns. These previous treatments, unique to patients with cancer, can adversely affect their cardiovascular, pulmonary, gastrointestinal, renal, and endocrine systems. This article also summarizes many important effects of a wide variety of chemotherapy agents in use today.
