Abstract
OBJECTIVE There is a growing literature on the risk of chronic disease among firefighters, including cardiovascular disease (CVD) and cancer. However there is little information on firefighter's perception thereof. METHODS Firefighters attending a union convention in New Jersey completed a survey with four domains: firefighting experience; perceived additional risk for chronic diseases (six-point Likert scale); cancer screening history; demographics, and risk behaviors. RESULTS Among 167 enrolled firefighters, all were men and 86.6% active career. Median perceived risk ranged from high risk (colon, hematologic, breast, prostate, and testicular cancers) to very high risk (CVD, pulmonary diseases, all cancers, lung and oral cancer). CONCLUSIONS NJ Firefighters attributed considerable additional risk to acquiring chronic disease as a result of their firefighting activities. Understanding firefighter perceptions of their own morbidity and mortality will help develop future firefighter preparatory programs.

Abstract
Operative management of emergency general surgery (EGS) diagnoses involves a range of procedures which can carry high morbidity and mortality. Little is known about the impact of obesity on patient outcomes. The aim of this study was to examine the association between body mass index (BMI) >30 kg/m2 and mortality for EGS patients. We hypothesized that obese patients would have increased mortality rates. A regional integrated health system EGS registry derived from The American Association for the Surgery of Trauma EGS ICD-9 codes was analyzed from January 2013 to October 2015. Patients were stratified into BMI categories based on WHO classifications. The primary outcome was 30-day mortality. Longer-term mortality with linkage to the Social Security Death Index was also examined. Univariate and multivariable analyses were performed. A total of 60 604 encounters were identified and 7183 (11.9%) underwent operative intervention. Patient characteristics include 53% women, mean age 58.2 ± 18.7 years, 64.2% >BMI 30 kg/m2, 30.2% with chronic obstructive pulmonary disease, 19% with congestive heart failure, and 31.1% with diabetes. The most common procedure was laparoscopic cholecystectomy (36.4%). Overall, 90-day mortality was 10.9%. In multivariable analysis, all classes of obesity were protective against mortality compared to normal BMI. Underweight patients had increased risk of inpatient (OR = 1.9, CI = 1.7-2.3), 30-day (OR = 1.9, CI = 1.7-2.1), 90-day (OR = 1.8, CI 1.6-2.0), 1-year (OR = 1.8, CI = 1.7-2.0), and 3-year mortality (OR = 1.7, CI = 1.6-1.9). When stratified by BMI, underweight EGS patients have the highest odds of death. Paradoxically, obesity appears protective against death, even when controlling for potentially confounding factors. Increased rates of nonoperative management in the obese population may impact these findings.

Abstract
OBJECTIVE Time spent on the Electronic Health Record (EHR) influences surgical residents' clinical availability. Objective data assessing EHR usage among surgical residents are lacking and necessary. DESIGN/PARTICIPANTS Active EHR usage data for 70 surgical residents were collected from April 2015 through April 2016. Active EHR usage was defined as more than 15 keystrokes, or 3 mouse clicks, or 1700 "mouse miles" per minute. Usage data of different specialties, interns (PGY 1), juniors (PGY 2, 3), and seniors (PGY 4, 5) were compared. SETTING Carolinas Medical Center, Charlotte, NC. RESULTS Interns spent more time than juniors on total EHR activities per day (134.5 vs 105.5 minutes, p < 0.001) and juniors spent more time per day than seniors (105.5 vs 78.7 minutes, p < 0.001). Among different EHR activities per patient, interns spent greater time than juniors on chart review (8.1 vs 6.2 minutes, p < 0.001), documentation (9.0 vs 6.5 minutes, p < 0.001), and orders (3.6 vs 3.0 minutes, p < 0.001). Juniors spent the same time as seniors on chart review (6.2 vs 6.5 minutes, p = 0.2). Juniors spent more time than seniors on documentation (6.5 vs 5.2 minutes, p < 0.001) and orders (3.0 vs 2.7 minutes, p < 0.05). Comparing EHR activities per patient among different specialties, General Surgery residents spent more time than Orthopedic residents on total EHR time (19.9 vs 15.9 minutes, p < 0.001), chart review (6.8 vs 5.7 minutes, p < 0.001), documentation (6.3 vs 5.6 minutes, p < 0.001), and orders (3.6 vs 2.6 minutes, p < 0.001). General Surgery residents spent less time than OB/GYN residents on total EHR time (19.9 vs 22 minutes, p < 0.01), chart review (6.8 vs. 7.5 minutes, p < 0.05), and documentation (6.3 vs 7.6 minutes, p < 0.001), but more time on orders (3.6 vs 2.9 minutes, p < 0.001). CONCLUSIONS These are the first reported objective findings on surgical resident use of the EHR and may provide an opportunity for improvement in EHR training and usage.

Low Vitamin D States Observed in U.S. Marines and Navy Sailors with Early Multi-Symptom Illness. Biomolecules 2020; 10:biom10071032.

Abstract
Research has implicated immune system inflammation as an underlying etiology of multi-symptom illnesses, and vitamin D has been shown to have a significant role in immune system function. In this retrospective review performed on the medical charts of service members who presented with signs and symptoms of multi-symptom illnesses, we focused on serum 25(OH)D3 levels and looked for associations of vitamin D status (deficient, insufficient, and normal) with age (20–31 years versus 31–56 years) and deployment status (war zones versus other). Two groups (U.S. Marines and Navy Sailors) were sampled and both showed high incidences of below normal vitamin D levels. However, with the Marines, age-related differences in serum levels (p = 0.009) were found only among those who deployed to Iraq/Afghanistan in comparison to those in non-combat locations. The comparison within the Navy sample showed that mobilized sailors had lower 25(OH)D3 levels than the group that did not deploy (p = 0.04). In addition, 100% of the sailors who deployed had below normal levels versus only 33% in the cadre group. The data suggest that personnel returning from a war zone with signs of early multi-symptom illness should be checked for low vitamin D status.

Abstract
Radiologic indicators of sarcopenia have been associated with adverse operative outcomes in some surgical populations. This study assesses the association of radiologic indicators of frailty with outcomes after open ventral hernia repair (OVHR). A prospective, institutional, herniaspecific database was queried for patients undergoing OVHR from 2007 to 2018 with preoperative CT. Psoas muscle cross-sectional area at L3 was measured and adjusted for height (skeletal muscle index (SMI)). L3 vertebral body density (L3 VBD) was measured. Demographics and outcomes were evaluated as related to SMI and L3 VBD. Of 1178 patients, 9.7 per cent of females and 15.8 per cent of males had sarcopenia and 11.6 per cent of females and 9.2 per cent of males had osteopenia. Neither sarcopenia nor osteopenia were associated with outcomes of wound infection, read-mission, reoperation, hernia recurrence, or major complications. When examined as continuous variables or by quartile, SMI and L3 VBD were not associated with adverse outcomes, including in subsets of male or female patients, the elderly, contaminated cases, and the obese. Radiologic markers of sarcopenia and osteopenia are not associated with adverse outcomes after OVHR. Further study should examine age or other potential predictors of outcomes in this patient population, such as independent status.

The impact of weight change on intra-abdominal and hernia volumes. Surgery 2020; 167:876-882. [PMID: 32151368 DOI: 10.1016/j.surg.2020.01.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 01/05/2020] [Accepted: 01/14/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Weight loss is often encouraged or required before open ventral hernia repair. This study evaluates the impact of weight change on total, intra-abdominal, subcutaneous, and hernia volume. METHODS Patients who underwent open ventral hernia repair from 2007 to 2018 with two preoperative computed tomography scans were identified. Scans were reviewed using 3D volumetric software. Demographics, operative characteristics, and outcomes were evaluated. The impact of weight change on intra-abdominal, subcutaneous, and hernia volume was assessed using Spearman's correlation coefficients and linear regression models. RESULTS A total of 250 patients met the criteria with a mean defect area of 155.6 ± 155.4 cm2, subcutaneous volume of 6,800.0 ± 3,868.8 cm3, hernia volume of 915.7 ± 1,234.5 cm3, intra-abdominal volume equaling 4,250.2 ± 2,118.1 cm3, and time between computed tomography scans 13.9 ± 11.0 months. Weight change was associated with change in hernia, intra-abdominal, total, and subcutaneous volume (Spearman's correlation coefficients 0.17, 0.48, 0.51, 0.45, respectively, P ≤ 0.03 all values) and not associated in hernia length, width, or area (P ≥ 0.18 all values). A Δ5 kg was significantly associated with Δintra-abdominal volume (164.1 ± 30.0 cm3/Δ5 kg,P < .0001), Δtotal volume (209.9 ± 33.0 cm3/Δ5 kg, P < .0001), and Δsubcutaneous volume (234.4 ± 50.8 cm3/Δ5 kg, P < .0001). Per Δ5 kg, male patients had more than double the Δintra-abdominal, Δtotal, and Δsubcutaneous volume than did female patients. A weight change of 5 kg to10 kg was associated with approximately double the change in computed tomography parameters/Δ5 kg than any weight change after 10 kg. Regardless of weight change, all measured hernia parameters increased over time, with mean hernia volume of +40.6 ± 94.9 cm3/mo and area of +7.8 ± 13.3 cm2/mo (Spearman's correlation coefficient -0.03 to 0.07, P value 0.37-0.96). CONCLUSION Weight change is linearly correlated with intra-abdominal and subcutaneous fat gain or loss. Males show greater abdominal-related response to weight gain or loss. Hernia dimensions increase over time regardless of weight change.

Abstract
BACKGROUND Up to 11% of patients report a penicillin allergy (PA), with 1-2% demonstrating a true IgE mediated allergy upon testing. PA patients often receive non-beta-lactam antibiotic surgical prophylaxis (non-BLP). This study evaluates the relationship of PA to outcomes after open ventral hernia repair (OVHR). METHODS A prospective institutional database was queried for patients undergoing OVHR. Demographics, operative characteristics, and outcomes were evaluated by the reported PA and the administration of beta-lactam prophylaxis (BLP). RESULTS Allergy histories were reviewed in 1178 patients. PA was reported in 21.6% of patients, with 55.5% reporting rash or hives, 15.0% airway compromise or anaphylaxis, and 29.5% no specific reaction. BLP was administered to 76.3% of patients, including 22.1% of PA patients and 89.9% of patients without PA. PA patients were more often female (64.6% PA patients vs. 56% non-PA, p = 0.01), with higher rates of chronic steroids, MRSA, anxiety, asthma, COPD, chronic pain, and sleep apnea (p < 0.03 all values). PA patients had higher rates of contaminated cases, including mesh infection and fistula. Of the 683 clean cases, 82.1% received BLP. Of the 117 clean contaminated cases (CDC wound class 2), 82.9% received BLP, which was associated with reduced long-term readmission for hernia complications (21.5 vs. 55%, p = 0.002, OR 0.27, CI 0.09-0.83). In the 120 CDC wound class 3 and 4 patients, 65.8% received BLP. In multivariate analysis, BLP was associated with lower rates of reoperation (OR 0.31, CI 0.12-0.76) and recurrence (OR 0.32, CI 0.11-0.86). BLP was given to 22.1% of the PA patients with no adverse reactions noted. CONCLUSION PA patients had more comorbidities and complex ventral hernias. When controlling for contamination and MRSA history, BLP is associated with improved outcomes particularly in contaminated cases. PA may be a risk factor for patient complexity, and further studies are warranted to determine if allergy testing can be warranted in known or anticipated contaminated cases.

Too big to breathe: predictors of respiratory failure and insufficiency after open ventral hernia repair. Surg Endosc 2019; 34:4131-4139.

Abstract
INTRODUCTION Increased intra-abdominal pressure in open ventral hernia repair (OVHR) is hypothesized to contribute to postoperative respiratory insufficiency (RI) or failure (RF). This study examines the impact of abdominal volumes on postoperative RI in OVHR. METHODS OVHR patients with preoperative CT scans were identified. 3D volumetric software measured hernia volume (HV), subcutaneous volume (SQV), and intra-abdominal volume (IAV). The ratio of hernia to intra-abdominal volume (HV:IAV) was calculated. A principal component analysis was performed to create new component variables for collinear volume and hernia variables. RESULTS There were 1178 OVHR patients with preoperative CT scans. Demographics included a mean BMI of 34.2 ± 7.7 kg/m2, age of 58.5 ± 12.4 years, and 57.8% were female. RI occurred in 8.3% of patients, including 4.0% requiring > 24 h respiratory support with ezPAP, CPAP, or biPAP (RI), and 4.3% requiring intubation (RF). Patients who developed RI had a higher BMI (33.8 ± 7.5 vs. 38.2 ± 9.1 kg/m2, p < 0.0001), older age (58.1 ± 12.5 vs. 62.8 ± 10.4 years, p = 0.0001), larger defects (140.9 ± 128.4 vs. 254.0 ± 173.9 cm2, p < 0.0001), HV (865.8 ± 1200.0 vs. 2005.6 ± 1791.7 cm3, p < 0.0001), and HV:IAV (0.26 ± 0.45 vs. 0.53 ± 0.58, p < 0.0001). Three PC variables accounted for 85% of variance: hernia volume PC consists primarily of HV (61.8%), ratio HV:IAV (57.7%), and defect size (50.1%) and accounts for 38.3% variance. Extra-abdominal volume PC consists primarily of SQV (63.7%) and BMI (60.8%) and accounts for 32.5% variance. Intra-abdominal volume PC is primarily IAV (75.8%) and accounts for 14.9% variance. In multivariate analysis, predictors of RI included asthma and COPD (OR 4.04, CI 1.82-8.96), hernia PC (OR 1.47, CI 1.48-1.98), EAV PC (OR 1.24, CI 1.04-1.48), increased age (OR 1.04, CI 1.01-1.06), and diabetes (OR 1.8, CI 1.11-2.91). Component separation, fascial closure, contamination, and panniculectomy were not associated with RI. CONCLUSION The impact of defect size, BMI, HV, SQV, IAV, and HV:IAV on respiratory insufficiency after OVHR is collinear. Patients with large defects and a large ratio of HV:IAV (greater than 0.5) are also at significantly increased risk of RI after OVHR. While BMI impacts these parameters, it is not directly predictive of postoperative RI.

Abstract
BACKGROUND Component separation technique (CST) allows fascial medialization during abdominal wall reconstruction (AWR). Wound contamination increases the incidence of wound complications, which multiplies the incidence of repair failure. The aim of this study was to compare the impact of CST on AWR outcomes in contaminated fields in comparison to those operations without CST. METHODS A prospective, single institution hernia database was queried for patients undergoing AWR with CST and contamination. A case control cohort was identified using propensity score matching. RESULTS There were 286 CSTs performed in contaminated cases. After propensity score matching, 61 CSTs were compared to 61 No-CSTs. These groups were matched by defect area (CST:287.1 ± 150.4 vs No-CST:277.6 ± 218.4 cm2, p = 0.156), BMI (32.0 ± 7.0 vs 32.2 ± 6.0 kg/m2, p = 0.767), diabetes (26.2% vs 32.8%, p = 0.427), and panniculectomy (52.5% vs 36.1%, p = 0.068). Groups had similar rates of wound complications (42.6% vs 40.7%, p = 0.829) and recurrence (4.9% vs 13.1%, p = 0.114). CONCLUSIONS The use of CST in the face of contamination is not associated with an increase in wound complications, mesh complications, or recurrence.

Abstract
BACKGROUND Placement of paraesophageal type of "mesh" in paraesophageal hernia repair is controversial. This study examines the trends and outcomes of mesh placement in paraesophageal hernia repair. METHODS The American College of Surgeons National Surgical Quality Improvement Program was queried for patients who underwent paraesophageal hernia repair with or without mesh (2010-2017). Demographics, operative approach, and outcomes were compared over time. RESULTS Of 25,801, most paraesophageal hernia repair cases were elective (89.3%), without mesh (61.9%), and performed laparoscopically (91.3%).When compared with open paraesophageal hernia repair patients, the patients undergoing laparoscopic paraesophageal hernia repair had lesser rates of reoperation, readmission, mortality, overall complications and major complications (2.7% vs 4.8%, 6.2% vs 9.6%, 0.6% vs 2.9%, 7.1% vs 21.3%, 3.8% vs 11.1%, respectively; all P < .0001). Mesh placement was more common in laparoscopic paraesophageal hernia repair (38.9 vs 29.7, P < .0001) than opern paraesophageal hernia repair. During 2010-2017, mesh placement decreased from 46.2% to 35.2% of laparoscopic paraesophageal hernia repair (P < .0001). Operative times for laparoscopic paraesophageal hernia repair decreased over time, and laparoscpic paraesophageal hernia repair without mesh was consistently less (with mesh: 176.0 ± 71.0 to 149.9 ± 72.5 min, without mesh: 148.6 ± 71.4 to 134.6 ± 70.4). We observed no changes in comorbidities or adverse outcomes over time. Using multivariate analysis to control for potential confounding factors, chronic obstructive pulmonary disease was associated most strongly with adverse outcomes, including mortality (OR 2.53, CI 1.55-4.14), any complications (OR 1.80, CI 1.51-2.16), major complications (OR 1.80, CI 1.51-2.16), readmission (OR 1.63, CI 1.33-1.99) and reoperation (OR 1.49, CI 1.10-2.02). Mesh placement was not associated with adverse outcomes. CONCLUSION The placement of mesh during laparoscopic paraesophageal hernia repair is not associated with adverse outcomes. Use of mesh with laparoscopic paraesophageal hernia repair is decreasing with no apparent adverse impact on short-term patient outcomes. Further research is needed to investigate patient factors not captured by this national database, such as characteristics of the hernia, patient symptoms, and hernia recurrence.

Vitamin D levels and monospot tests in military personnel with acute pharyngitis: a retrospective chart review. PLoS One 2014; 9:e101180.

Abstract
Some recent studies have proposed an important role for vitamin D in reducing the risk of infection by assisting in the suppression of viruses and by controlling the inflammatory response. A low vitamin D state may have a detrimental effect on the immune system's ability to produce activated CD8+ T cells, and it may increase the inflammatory reaction to Epstein Barr virus. The aim of this chart review was to see if serum 25 OH vitamin D3 levels in service members with acute pharyngitis were lower in those who had positive rather than negative monospot tests. A retrospective chart review was conducted on the medical records of service members who presented to sick call at Camp Lejeune, NC with acute pharyngitis from October 8, 2010 until June 30, 2011. Serum 25 OH vitamin D3 levels were compared between those with positive and negative monospot test results. Of the 25 records that were reviewed, there were 9 (36%) service members with positive results, and they were found to have lower vitamin D levels (Median = 20.80 ng/ml, Interquartile range = 10.15) than those with negative test results (Median = 30.35 ng/ml, Interquartile range = 17.05), Mann-Whitney U = 41, p = .039. Only 1 of the 9 with positive test results had a normal serum 25 OH vitamin D3 level (30 ng/ml or greater) compared with 9 of the 16 with negative test results. Optimal vitamin D stores may play a significant role in reducing the risk of developing acute mononucleosis but larger, prospective studies will be needed to verify these findings.

Abstract
A latent viral immune inflammatory response (LVIIR) model is presented which integrates factors that contribute to chronic multisymptom illness (CMI) in both the veteran and civilian populations. The LVIIR model for CMI results from an integration of clinical experience with a review of the literature in four distinct areas: (1) studies of idiopathic multisymptom illness in the veteran population including two decades of research on Gulf War I veterans with CMI, (2) new evidence supporting the existence of chronic inflammatory responses to latent viral antigens and the effect these responses may have on the nervous system, (3) recent discoveries concerning the role of vitamin D in maintaining normal innate and adaptive immunity including suppression of latent viruses and regulation of the immune inflammatory response, and (4) the detrimental effects of extreme chronic repetitive stress (ECRS) on the immune and nervous systems. The LVIIR model describes the pathophysiology of a pathway to CMI and presents a new direction for the clinical assessment of CMI that includes the use of neurological signs from a physical exam, objective laboratory data, and a new proposed latent viral antigen-antibody imaging technique for the peripheral and central nervous system. The LVIIR model predicts that CMI can be treated by a focus on reversal of immune system impairment, suppression of latent viruses and their antigens, and healing of nervous system tissue damaged by chronic inflammation associated with latent viral antigens and by ECRS. In addition, the LVIIR model suggests that maintaining optimal serum 25 OH vitamin D levels will maximize immune system suppression of latent viruses and their antigens and will minimize immune system inflammation. This model also emphasizes the importance of decreasing ECRS to improve immune system function and to minimize nervous system injury from excess serum glucocorticoid levels. The proposed model supports growing evidence that increasing omega 3 essential fatty acid levels in nervous system tissues may decrease inflammation in the nervous system and improve neural plasticity and recovery from neuronal injury.

Abstract
OBJECTIVE A technique is presented for generating and recording lingual and palatine nerve somatosensory evoked potentials (SEPs). METHODS Pairs of thin, stainless steel disk electrodes were mounted onto mandibular or maxillary acrylic splints, similar to orthodontic retainers. Mandibular splint electrodes were oriented to contact the under surface of the tongue along the course of the right and left lingual nerves and maxillary splint electrodes were oriented to contact the hard palate bilaterally along the course of the palatine nerves. SEP recording electrodes were placed on the scalp 1 cm posterior to C5 and C6 (C5' and C6', respectively) using the combinatorial nomenclature of the International 10-20 system. Two reference electrode locations, Fz and C5' or C6', over the cortical hemisphere opposite that of the recording electrode, were used. RESULTS Right and left lingual and palatine nerve SEPs were recorded from five normal adults. SEP latencies were similar to the N13 and P18 cortical peak latencies recorded in previous studies of trigeminal nerve branches to the lips regardless of reference electrode position. CONCLUSIONS A more precise method of stimulating the intraoral lingual and palatine nerves was accomplished using dental splints. SEPs were easier to obtain using a contralateral cortex reference electrode location.
