The efficacy of goal-directed recommendations in overcoming barriers to elective ventral hernia repair in older adults.

BACKGROUND: Although ventral hernias are common in older adults and can impair quality of life, multiple barriers exist that preclude ventral hernia repair. The goal of this study was to determine if older adults with ventral hernias achieve surgeon-directed goals to progress to an elective ventral hernia repair. METHODS: Patients ≥60 years evaluated for a ventral hernia in a specialty clinic from January 2018 to August 2021 were retrospectively reviewed. Nonoperative candidates with modifiable risk factors were included. Data collected included specific barriers to ventral hernia repair and recommendations to address these barriers for future ventral hernia repair eligibility. Patients lost to follow-up were contacted by phone. RESULTS: In total, 559 patients were evaluated, with 182 (32.6%) deemed nonoperative candidates with modifiable risk factors (median age 68 years, body mass index 38.2). Surgeon-directed recommendations included weight loss (53.8%), comorbidity management by a medical specialist (44.0%), and smoking cessation (19.2%). Ultimately, 45/182 patients (24.7%) met preoperative goals and progressed to elective ventral hernia repair. Alternatively, 5 patients (2.7%) required urgent/emergency surgical intervention. Importantly, 106/182 patients (58.2%) did not return to clinic after initial consultation. Of those contacted (n = 62), 35.5% reported failure to achieve optimization goals. Initial body mass index ≥40 and surgeon-recommended weight loss were associated with lack of patient follow-up (P = .01, P = .02) and progression to elective ventral hernia repair (P = .009, P = .005). CONCLUSION: Nearly one-third of older adults evaluated for ventral hernias were nonoperative candidates, most often due to obesity, and over half of these patients were lost to follow-up. An increase in structured support is needed for patients to achieve surgeon-specified preoperative goals.

Polypharmacy is predictive of postoperative complications in older adults undergoing ventral hernia repair.

BACKGROUND: Ventral hernias are common in older adults, and may be repaired via a transversus abdominus release (TAR). Older adults undergoing surgery have unique age-related risk factors, including polypharmacy. Polypharmacy is highly prevalent in older adults and is associated with adverse postoperative outcomes. Our aim was to examine the prevalence and association of polypharmacy with clinical outcomes in older adults undergoing a TAR. METHODS: Patients 60 years and older who underwent elective open or robotic bilateral TAR were included in the study. Average daily medications taken preoperatively was collected and stratified by tertiles. Baseline demographic data, peri- and postoperative outcomes, and 30-day outcomes were collected. RESULTS: There were 132 total patients with an average age of 67.8 years. The number of daily medications ranged from 0 to 28, with an overall mean of 11.2 medications. Patients in tertile 1 took an average of 5.3 medications, tertile 2 10.5 medications, and tertile 3 17.9 medications. Patients in tertile 3 had more than double the rate of in-hospital complications (0.7) compared to tertiles 1 and 2 (0.3 and 0.3, respectively; p = 0.03). A greater number of daily medications was independently associated with postoperative delirium [odds ratio (OR) 1.2, 95% confidence interval (CI) 1.0-1.3], cardiac events (OR 1.2, 95% CI 1.0-1.3), ICU stay (OR 1.2, 95% CI 1.0-1.3), and discharge to a skilled nursing facility (SNF) (OR 1.2, 95% CI 1.0-1.5). CONCLUSIONS: Polypharmacy was very common in older adults undergoing a TAR, and was associated with in-hospital complications, postoperative delirium, cardiac events, ICU stay, length of stay, and discharge to a SNF. Additional study is needed to assess if preoperative interventions to limit polypharmacy will improve outcomes for older adults undergoing a TAR.

Perioperative outcomes of the Geriatric Assessment and Medical Preoperative Screening (GrAMPS) program pilot for older hernia patients: does chronological age predict outcomes?

BACKGROUND: The Geriatric Assessment and Medical Preoperative Screening (GrAMPS) program was an initial attempt to understand and to define the prevalence of age-related risk factors in older patients undergoing elective ventral hernia repair (VHR) or inguinal hernia repair (IHR). Preliminary analysis found significant rates of previously unrecognized objective cognitive dysfunction, multimorbidity and polypharmacy. We now examine whether chronological age as a sole risk factor can predict a patient's perioperative outcomes, and if traditional risk calculators that rely heavily on chronological age can accurately capture a patient's true risk. METHODS: This was a retrospective secondary analysis of the previously reported GrAMPS trial enrolling patients 60 years and older with a planned elective repair of a ventral or inguinal hernia. The rates of key postoperative outcomes were compared between various cohorts stratified by chronological age. Previously validated risk screening calculators [Charlson Comorbidity Index (CCI), National Surgical Quality Improvement Program (NSQIP)] were compared between cohorts. RESULTS: In total, 55 (78.6%) of the 70 patients enrolled in GrAMPS underwent operative intervention by May 2021, including 26 VHR and 29 IHRs. Cohorts stratified by chronological age had similar rates of key perioperative wound and age-related outcomes including readmissions, postoperative complications, non-home discharges, and length of stay. Additionally, while the commonly used risk calculators, CCI and NSQIP, consistently predicted worse outcomes for older hernia patients (stratified by both median age and age-tertiles), screening positive on these risk assessments were not actually predictive of a greater incidence of postoperative complications. CONCLUSIONS: Chronological age does not accurately predict worse adverse postoperative complications in older hernia patients. Additionally, traditional risk screening calculators that rely heavily on age to risk stratify may not accurately capture a patient's true surgical risk. Surgeons should continue to explore nuanced patient risk assessments that more accurately capture age-related risk factors to better individualize perioperative risk.

Chronological age does not predict postoperative outcomes following transversus abdominis release (TAR).

BACKGROUND: Transversus abdominis release (TAR) is an effective procedure for the repair of complex ventral hernias. However, TAR is not a low risk operation, particularly in older adults who are disproportionately affected by multiple age-related risk factors. While past studies have suggested that age alone inconsistently predicts patient outcomes, data regarding age's effect on postoperative outcomes and wound complications following a TAR are lacking. METHODS: Patients who underwent either an open or robotic bilateral TAR from 1/2018 to 9/2020 were eligible for the study. Patients were stratified by age groups (≥ 60 years vs. < 60 years and < 60, 60-70, and ≥ 70) and by both age and operative approach. The rates of key postoperative outcomes and wound morbidity were compared between the various cohorts. RESULTS: A total of 300 patients were included: 165 patients were ≥ 60 and 135 patients were < 60. Cohorts stratified by age were well-matched for important hernia factors: defect size (p = 0.31), BMI ≥ 30 (p = 0.46), OR time (p = 0.25), percent open TAR (p = 0.42), diabetes (p = 0.45) and history of prior surgical site infection (p = 0.40). The older cohort had significantly higher rates of coronary artery disease, hypertension, and COPD. On univariate analysis, cohorts stratified by age had similar rates of key postoperative and wound complications including in-hospital complications (p = 0.62), length of stay (p = 0.47), readmissions (p = 0.66), and surgical site occurrences (p = 0.68). Additionally, cohorts stratified by both age and operative approach also had similar outcomes. Multivariate analysis showed that chronological age was not independently associated with surgical site occurrences (p = 0.22), readmissions (p = 0.99), in-hospital complications (p = 0.15), or severe complications (p = 0.79). CONCLUSION: Open and robotic TARs can be safely performed in older adults and chronological age alone is a poor predictor of patient morbidity following TAR. Further investigation of alternative preoperative screening tools that do not rely solely on age are needed to better optimize surgical outcomes in older adults following TAR.

Does immunosuppression increase perioperative wound morbidity in patients undergoing transversus abdominis release?

BACKGROUND: Transversus abdominis release is an effective procedure for complex ventral hernias. As wound complications contribute to hernia recurrences, mitigating risk factors is vitally important for hernia surgeons. Although immunosuppression can impair wound healing, it has inconsistently predicted wound occurrences, and its effect on wound morbidity after a transversus abdominis release is unknown. METHODS: Patients undergoing either an elective open or robotic bilateral transversus abdominis release with permanent synthetic mesh were retrospectively stratified by perioperative immunosuppression and secondarily by procedure type (open versus robotic) and immunosuppression. RESULTS: A total of 321 patients were included for analysis. Overall, 63 (19.6%) patients were on chronic immunosuppression, with history of solid-organ transplant being the most common indication (43 patients). Patients stratified by perioperative immunosuppression were well-matched with similar defect size (P = .97), body mass index ≥30 (P = .32), diabetes (P = .09), history of surgical site infection (P = .53), surgical approach (P = .53), and tobacco use history (P = .33). No differences between cohorts were elicited for any wound event when stratified by immunosuppression use. Similarly, no differences were elicited when cohorts were further stratified also by procedure type. CONCLUSION: Chronic immunosuppression is often viewed as a notable risk factor for wound occurrences after surgery. However, our data suggest immunosuppression may not significantly increase the risk of perioperative wound morbidity follow transversus abdominis release as previously predicted.

Transversus abdominis release with posterior component separation in patients with previously recurrent ventral hernias: A single institution experience.

BACKGROUND: Recurrent hernias pose significant challenges due to violated anatomic planes, resultant scar, and potential prior mesh. Transversus abdominis release has been widely utilized for complex hernias. Transversus abdominis release can provide a novel plane for dissection and mesh placement for recurrent hernias. This study provides our institution's experience with transversus abdominis release in patients with recurrent ventral hernias. METHODS: A retrospective chart review was conducted of patients with recurrent ventral hernias from January 2018 to September 2020 who underwent transversus abdominis release by 2 fellowship-trained abdominal wall surgeons. Combined procedures (ie, gynecological/urological), robotic totally extraperitoneal, and emergency cases were excluded. Demographics, perioperative, and postoperative outcomes were reviewed. RESULTS: In total, 108 patients underwent open-transversus abdominis release and 25 had robotic-transversus abdominis release for recurrent ventral hernias. All patients received a lightweight to midweight nonabsorbable polypropylene synthetic mesh. Mean age was 59, mean body mass index was 34 kg/m2, with mean hernia defect area of 333 cm2. We noted 34 (25.6%) surgical site occurrences and 11 (8.3%) surgical site infections. Mean postoperative follow-up was 15.5 months, with 7 (5%) recurrences (6 open-transversus abdominis release, 1 robotic-transversus abdominis release). A minimum 12-month follow-up was available for 62% of patients, and minimum 6-month follow-up in 80% of patients. CONCLUSION: Recurrent hernias pose significant operative challenges for surgeons due to violated tissue planes and limited repair options. Our experience suggests that transversus abdominis release may provide a durable repair for difficult recurrent ventral hernias. However, long-term postoperative follow-up over multiple years is still needed to establish extended durability of transversus abdominis release in these patients.

Quercetin Preserves Oral Cavity Health by Mitigating Inflammation and Microbial Dysbiosis.

Failure to attenuate inflammation coupled with consequent microbiota changes drives the development of bone-destructive periodontitis. Quercetin, a plant-derived polyphenolic flavonoid, has been linked with health benefits in both humans and animals. Using a systematic approach, we investigated the effect of orally delivered Quercetin on host inflammatory response, oral microbial composition and periodontal disease phenotype. In vivo, quercetin supplementation diminished gingival cytokine expression, inflammatory cell infiltrate and alveolar bone loss. Microbiome analyses revealed a healthier oral microbial composition in Quercetin-treated versus vehicle-treated group characterized by reduction in the number of pathogenic species including Enterococcus, Neisseria and Pseudomonas and increase in the number of non-pathogenic Streptococcus sp. and bacterial diversity. In vitro, Quercetin diminished inflammatory cytokine production through modulating NF-κB:A20 axis in human macrophages following challenge with oral bacteria and TLR agonists. Collectively, our findings reveal that Quercetin supplement instigates a balanced periodontal tissue homeostasis through limiting inflammation and fostering an oral cavity microenvironment conducive of symbiotic microbiota associated with health. This proof of concept study provides key evidence for translational studies to improve overall health.

A20 Orchestrates Inflammatory Response in the Oral Mucosa through Restraining NF-κB Activity.

Deregulated immune response to a dysbiotic resident microflora within the oral cavity leads to chronic periodontal disease, local tissue destruction, and various systemic complications. To preserve tissue homeostasis, inflammatory signaling pathways involved in the progression of periodontitis must be tightly regulated. A20 (TNFAIP3), a ubiquitin-editing enzyme, has emerged as one of the key regulators of inflammation. Yet, the function of A20 in the oral mucosa and the biological pathways in which A20 mitigates periodontal inflammation remain elusive. Using a combination of in vivo and ex vivo disease models, we report in this study that A20 regulates inflammatory responses to a keystone oral bacterium, Porphyromonas gingivalis, and restrains periodontal inflammation through its effect on NF-κB signaling and cytokine production. Depletion of A20 using gene editing in human macrophage-like cells (THP-1) significantly increased cytokine secretion, whereas A20 overexpression using lentivirus infection dampened the cytokine production following bacterial challenge through modulating NF-κB activity. Similar to human cells, bone marrow-derived macrophages from A20-deficient mice infected with P. gingivalis displayed increased NF-κB activity and cytokine production compared with the cells isolated from A20-competent mice. Subsequent experiments using a murine ligature-induced periodontitis model showed that even a partial loss of A20 promotes an increased inflammatory phenotype and more severe bone loss, further verifying the critical function of A20 in the oral mucosa. Collectively, to our knowledge, these findings reveal the first systematic evidence of a physiological role for A20 in the maintenance of oral tissue homeostasis as a negative regulator of inflammation.

The number of inpatient consultations is negatively correlated with patient satisfaction in patients with prolonged hospital stays.

BACKGROUND: Patient satisfaction is often measured using the Hospital Consumer Assessment of Healthcare Providers and Systems survey. Our aim was to examine the structural and clinical determinants of satisfaction among inpatients with prolonged lengths of stays (LOS). METHODS: Adult patients who were admitted between 2009 and 2012, had a LOS of 21 days or more, and completed the Hospital Consumer Assessment of Healthcare Providers and Systems survey, were included. Univariate analyses assessed the relationship between satisfaction and patient/system variables. Recursive partitioning was used to examine the relative importance of the identified variables. RESULTS: One hundred one patients met inclusion criteria. The average LOS was 35 days and 58% were admitted to a surgical service. Satisfaction with physician communication was significantly associated with fewer consultations (P < .01), nonoperative admission (P < .001), no intensive care unit stay (P < .01), nonsurgical service (P < .01), and non-emergency room admissions (P = .03). Among these, having fewer consultations had the highest relative importance. CONCLUSIONS: In long stay patients, having fewer inpatient consultations was the strongest predictor of patient satisfaction with physician communication. This suggests that examination of patient-level data in clinically relevant subgroups may be a useful way to identify targets for quality improvement.

Association of Patient-Reported Readiness for Discharge and Hospital Consumer Assessment of Health Care Providers and Systems Patient Satisfaction Scores: A Retrospective Analysis.

BACKGROUND: Patient-reported outcomes (PRO) have been increasingly emphasized, however, determining clinically valuable PRO has been problematic and investigation limited. This study examines the association of readiness for discharge, which has been described previously, with patient satisfaction and readmission. STUDY DESIGN: Data from adult patients admitted to our institution from 2009 to 2012 who completed both the Hospital Consumer Assessment of Healthcare Providers and Systems and the Press Ganey surveys post discharge were extracted from an existing database of patients (composed of 220 patients admitted for small bowel obstruction and 98 patients with hospital stays ≥ 21 days). Using the survey question, "Did you feel ready for discharge?" (RFD), 2 groups were constructed, those RFD and those with lesser degrees of readiness (ie, less ready for discharge [LRFD]) using topbox methodology. Outcomes, readmission rates, and satisfaction were compared between RFD and LRFD groups. RESULTS: Three hundred and eighteen patients met the inclusion criteria; 45% were female and 94% were Caucasian. Median age was 62.3 years (interquartile range 52.5 to 70.8 year). Median length of stay was 10 days (interquartile range 6.0 to 24.0 days) and 69.2% were admitted with small bowel obstruction. The 30-day readmission rate was 14.3% and 55% indicated they were RFD. Those RFD and LRFD had similar demographics, comorbidity scores, and rates of surgery. Those RFD had higher overall hospital satisfaction (87.3% RFD vs 62.4% LRFD; p < 0.001), higher physician communication scores (median 3.0 RFD vs 2.0 LRFD; p < 0.001), and higher nursing communication scores (median 3.0 RFD vs 2.0 LRFD, p < 0.001). Readmission rates were similar between the groups (11.4% RFD vs 18.2% LRFD; p = 0.09). CONCLUSIONS: Readiness for discharge appears to be a clinically useful patient-reported metric, as those RFD have higher satisfaction with the hospital and physicians. Prospective investigation into variables affecting patient satisfaction in those LRFD is needed.

Elevated parathyroid hormone after parathyroidectomy delays symptom improvement.

BACKGROUND: Curative parathyroidectomy for primary hyperparathyroidism (PHPT) resolves various nonspecific symptoms related to the disease. Between 8% and 40% of patients with normocalcemia after parathyroidectomy have persistently elevated parathyroid hormone (ePTH) levels at follow-up. We investigated whether ePTH in the early postoperative period was associated with the timing of symptom improvement. MATERIALS AND METHODS: This prospective study included adult patients with PHPT who underwent curative parathyroidectomy from November 2011 to September 2012. Biochemical testing at 2 wk postoperatively identified ePTH (defined as PTH>72 pg/mL) versus normal PTH (nPTH). A questionnaire administered pre- and post-operatively at 6 wk and 6 mo asked patients to rate the frequency of 18 symptoms of PHPT on a five-point Likert scale. Student t-tests were used to compare pre- with postoperative changes in scores for individual symptoms. RESULTS: Of 194 patients who underwent parathyroidectomy, 129 (66%) participated in the study. Preoperatively, all patients were symptomatic, with a mean of 13±4 symptoms. Two weeks postoperatively, 20 patients (16%) had ePTH. The percentage of patients with postoperative improvement for individual symptoms was compared between groups. At the early time point (6 wk), the ePTH group showed less improvement in 14 of 18 symptoms. This difference reached statistical significance for four symptoms: anxiety, constipation, thirst, and polyuria. By the 6-mo time point, these differences had resolved, and symptom improvement was similar between groups. CONCLUSIONS: ePTH after curative parathyroidectomy may result in a delay in symptom improvement 6 wk postoperatively; however, this difference resolves in 6 mo.
