Objectives: The purpose of the present study was to assess and describe the severity of symptoms reported by Covid-19 positive patients who vaped (smoked e-cigarettes) when compared to those who did not vape or smoke at the time of the diagnosis of Covid-19. Methods: Patients from this study are from a well-characterized patient cohort collected at Mayo Clinic between March 1, 2020 and February 28, 2021; with confirmed COVID-19 diagnosis defined as a positive result on reverse-transcriptase–polymerase-chain-reaction (RT-PCR) assays from nasopharyngeal swab specimens. Among the 1734 eligible patients, 289 patients reported current vaping. The cohort of vapers (N = 289) was age and gender matched to 1445 covid-19 positive patients who did not vape. The data analyzed included: date of birth, gender, ethnicity, race, marital status, as well as lifestyle history such as vaping and smoking and reported covid-19 symptoms experienced. Results: A logistic regression analysis was performed separately for each symptom using generalized estimating equations (GEE) with robust variance estimates in order to account for the 1:5 age, sex, and race matched set study design. Patients who vaped and developed Covid-19 infection were more likely to have chest pain or tightness (16% vs 10%, vapers vs non vapers, P = .005), chills (25% vs 19%, vapers vs non vapers, P = .0016), myalgia (39% vs 32%, vapers vs non vapers, P = .004), headaches (49% vs 41% vapers vs non vapers, P = .026), anosmia/dysgeusia (37% vs 30%, vapers vs non vapers, P = .009), nausea/vomiting/abdominal pain (16% vs 10%, vapers vs non vapers, P = .003), diarrhea (16% vs 10%, vapers vs non vapers, P = .004), and non-severe light-headedness (16% vs 9%, vapers vs non vapers, P < .001). Conclusion: Vapers experience higher frequency of covid-19 related symptoms when compared with age and gender matched non-vapers. Further work should examine the impact vaping has on post-covid symptom experience.

Abstract Coronavirus disease 2019 (COVID‐19), after initially being detected in Wuhan, China in late 2019, quickly spread to most regions of the world, meeting World Health Organization criteria for a pandemic. Social distancing along with other measures implemented to control spread had a drastic impact on the provision of healthcare including deferred elective procedures and surgeries as well as delayed care and evaluation for emergent diagnoses such as heart attacks and strokes. In the home nutrition practice, patients began to delay routine laboratory tests and were canceling or deferring annual visits. Our group soon began to rapidly deploy telehealth to meet the needs of the home nutrition patients. Telehealth is not a new concept with descriptions of healthcare being provided at a distance with the use of telephone in the 1870s. However, widespread adoption has been limited because of regulation (licensure, prescriptions, credentialing, and privileges), lack of reimbursement, as well as adoption and availability of technology needed to carry out telehealth visits. As regulations and limits on reimbursements were waived during COVID‐19 pandemic, our home nutrition practice began to evaluate core components of the care we provide for our patients and assess which could be successfully transitioned to telehealth. In addition to the history and regulation of telehealth, the current manuscript provides details regarding successful implementation of telehealth visits such as change management, selection of telehealth platform, scheduling and logistics, as well as carrying out the virtual visit including history and physical exam.

Objective To develop and implement criteria for description of post COVID syndrome based on analysis of patients presenting for evaluation at Mayo Clinic Rochester between November 2019 and August 2020. Methods A total of 465 patients with a history of testing positive for COVID-19 were identified and their medical records reviewed. After a thorough review, utilizing the DELPHI methods by an expert panel, 42 (9%) cases were identified with persistent central sensitization (CS) symptoms persisting after the resolution of acute COVID-19, herein referred to as Post COVID syndrome (PoCoS). In this report we describe the baseline characteristics of these PoCoS patients. Results Among these 42 PoCoS patients, the mean age was 46.2 years (median age was 46.5 years). Pain (90%), fatigue (74%), dyspnea (43%), and orthostatic intolerance (38%) were the most common symptoms. The characteristics of an initial 14 patients were utilized for the development of clinical criteria via a modified Delphi Method by a panel of experts in central sensitization disorders. These criteria were subsequently applied in the identification of 28 additional cases of suspected PoCoS. A 2-reviewer system was used to analyze agreement with using the criteria, with all 28 cases determined to be either probable or possible cases by the reviewers. Inter-reviewer agreement using these proposed defining criteria was high with a Cohen’s alpha of .88. Conclusions Here we present what we believe to be the first definitional criteria for Post COVID syndrome. These may be useful in clinical phenotyping of these patients for targeted treatment and future research.

Objective Persistent post-COVID symptoms are estimated to occur in up to 10% of patients who have had COVID-19. These lingering symptoms may persist for weeks to months after resolution of the acute illness. This study aimed to add insight into our understanding of certain post-acute conditions and clinical findings. The primary purpose was to determine the persistent post COVID impairments prevalence and characteristics by collecting post COVID illness data utilizing Patient-Reported Outcomes Measurement Information System (PROMIS ® ). The resulting measures were used to assess surveyed patients physical, mental, and social health status. Methods A cross-sectional study and 6-months Mayo Clinic COVID recovered registry data were used to evaluate continuing symptoms severity among the 817 positive tested patients surveyed between March and September 2020. The resulting PROMIS ® data set was used to analyze patients post 30 days health status. The e-mailed questionnaires focused on fatigue, sleep, ability to participate in social roles, physical function, and pain. Results The large sample size (n = 817) represented post hospitalized and other managed outpatients. Persistent post COVID impairments prevalence and characteristics were determined to be demographically young (44 years), white (87%), and female (61%). Dysfunction as measured by the PROMIS ® scales in patients recovered from acute COVID-19 was reported as significant in the following domains: ability to participate in social roles (43.2%), pain (17.8%), and fatigue (16.2%). Conclusion Patient response on the PROMIS ® scales was similar to that seen in multiple other studies which used patient reported symptoms. As a result of this experience, we recommend utilizing standardized scales such as the PROMIS ® to obtain comparable data across the patients’ clinical course and define the disease trajectory. This would further allow for effective comparison of data across studies to better define the disease process, risk factors, and assess the impact of future treatments.

Abstract Background We sought to estimate the incidence of home parenteral nutrition (HPN) use in a population-based cohort of patients with Crohn disease (CD), and to assess clinical outcomes and complications associated with HPN. Methods We used the Rochester Epidemiology Project (REP) to identify residents of Olmsted County, who were diagnosed with CD between 1970 and 2011, and required HPN. Results Fourteen out of 429 patients (3.3%) with CD received HPN (86% female). Eleven patients (79%) had moderate–severe CD and 12 patients (86%) had fistulizing disease. Thirteen patients (93%) underwent surgery, primarily due to obstruction. Among CD incidence cases, the cumulative incidence of HPN from the date of CD diagnosis was 0% at 1 year, 0.5% at 5 years, 0.8% at 10 years, and 2.4% at 20 years. Indications for HPN included short bowel syndrome in 64%, malnutrition in 29%, and bowel rest in 21%. The median duration of HPN was 2.5 years. There was an average weight gain of 1.2 kg at 6 months, an average weight loss of 1.4 kg at 1 year, and a further weight loss of 2.2 kg at 2 years from the start of HPN. Patients were hospitalized a mean of 5 times after the start of HPN, mainly due to catheter-related bloodstream infections and thrombosis. Conclusions Less than 4% of patients with CD need HPN. Most have moderate to severe disease with short bowel syndrome or malnutrition. Possible reasons for the patients’ weight loss could be noncompliance, and increased metabolic needs because of active disease.

Abstract Background High–ω‐6 polyunsaturated fatty acids (PUFAs) are noted to contribute to development of intestinal failure–associated liver disease (IFALD) in home parenteral nutrition (HPN). Fish oil (FO) has been added to latest generation of lipid injectable emulsion (ILE) to increase ω‐3:ω‐6 PUFA ratio; however, appropriate dose of FO to treat IFALD is unknown. Methods After approval of exclusive FO ILE in the US for pediatric patients, we noted 2 adult patients with ongoing IFALD despite transition to mixed‐oil (MO) ILE. They were transitioned to off‐label FO ILE after review of literature regarding use of FO ILE in adult HPN patients was conducted to guide management. Results The first case involves a 40‐year‐old female receiving HPN with IFALD refractory to MO ILE. MO ILE (with 15% FO) was provided at 50 g/d for 3 d/wk and combined with FO ILE at 50 g/d for 4 d/wk. This combination resulted in improvement in liver studies and allowed for decrease in dextrose calories. The second case involves a 49‐year‐old male receiving HPN (secondary to complications of necrotizing pancreatitis) who developed IFALD. FO ILE was used as the sole source of lipids and led to improvement in liver function tests. No evidence of essential fatty acid deficiency was found in either case. Conclusions Current case presentations and review of literature support the use of FO ILE to increase ω‐3 PUFAs in patients with IFALD refractory to MO ILE. Additional research is necessary to delineate the dose of FO ILE necessary to achieve benefit.

AbstractBackgroundPatients with chronic intestinal failure who require long‐term parenteral nutrition rely on central venous catheters (CVCs) for access to nutrition and hydration. With prolonged use, complications such as central line–associated bloodstream infection (CLABSI), damage to CVC, and central venous thrombosis (CVT) can threaten the availability of life‐preserving access. Because of this, all efforts should be made to preserve CVCs with techniques such as catheter salvage in case of CLABSI and catheter repair when damaged. The present study was conducted to evaluate the effectiveness and safety of catheter repair in our patient population.MethodsRetrospective review in 1253 adult patients who received home parenteral nutrition at the Mayo Clinic between September 1, 1997, and April 30, 2018, was conducted to determine the incidence of CLABSI and CVT in patients who underwent CVC repair.ResultsFifty‐five CVC repairs were performed in 36 patients (n = 23 female) with mean age of 57.05 ± 16.96 years. A total of 14 catheters (25.45%) were complicated with 24 episodes of CLABSI. CLABSI rate before and after repair was 0.23/1000 catheter days and 0.21/1000 catheter days, respectively. Most common indications for eventual catheter replacement were mechanical damage (32%), infection (32%), and switching to alternate mode of nutrition (24%). We had a 100% success rate of catheter repair procedure, and no post‐procedural complications were present.ConclusionCatheter repair can increase the catheter survival without increasing the risk of CLABSI, providing not only socioeconomic benefit but also decreasing risk of compromising future vascular access.

Objective To assess whether the Berlin Sleep Questionnaire and the Snoring, Tired, Observed, Pressure, Body mass, Age, Neck, and Gender questionnaire (STOP-BANG) might be suitable replacements for an overnight sleep pulse oximetry as screening tools for sleep disordered breathing in patients with fibromyalgia. Participants: From June 8, 2018 through July 25, 2018, adult patients with a confirmed diagnosis of fibromyalgia (via the 1990 and/or 2010 American College of Rheumatology Fibromyalgia Classification Criteria) who attended Mayo Clinic’s Fibromyalgia Treatment Program were invited to participate in the study. Methods: The design was a prospective comparative study with a retrospective chart review component. Participants completed 2 validated surveys: the Berlin Sleep Questionnaire and the STOP-BANG. Medical records were reviewed for demographic information and overnight pulse oximetry test results. Results: Results from both questionnaires indicate that there is an association between sleep apnea risk category (defined by questionnaire) and oximetry results. Fisher’s exact test for STOP-BANG and Berlin Sleep Questionnaire are statistically significant ( P < .001), indicating that participants at high risk for sleep apnea (based on the questionnaires) had a greater prevalence of abnormal oximetry results than those at low risk for sleep apnea. Participants who were classified as high risk (85.7%) or intermediate risk (61.5%) on the STOP-BANG questionnaire for sleep apnea had abnormal oximetry results. Participants who scored as high risk (85.7%) for sleep apnea on the Berlin Sleep Questionnaire had abnormal oximetry results. Conclusions: In patients with fibromyalgia, the Berlin Sleep Questionnaire and the STOP-BANG questionnaires could be beneficial in determining the probability of obstructive sleep apnea and the subsequent need for pulse oximetry testing, in higher risk patients.

Abstract Background : Although home parenteral nutrition (HPN) is lifesaving for patients with chronic intestinal failure (IF), long‐term use can be associated with complications such as infections, metabolic abnormalities, and IF–associated liver disease (IFALD). The key to treatment of many of these complications is prevention. Guidelines recommend avoidance of overfeeding, use of oral/enteral nutrition if possible, cyclic PN, and maintaining dose of soybean oil (SO) intravenous lipid emulsion (ILE) <1 g/kg/day as preventive strategies for IFALD. Additionally, with development of IFALD, ω‐6/ω‐3 polyunsaturated fatty acid ratio should be decreased in ILE. The newly available mixed‐oil (MO) ILE offers such an opportunity; however, there is a paucity of long‐term data available. Methods : The current study reports our long‐term experience with MO ILE use in HPN patients. Results : Seventeen patients (8 female and 9 male) with an average age of 47 ± 12 years and median HPN duration of 4.6 years (1.1–32.1 years) have utilized MO ILE for >12 months after being transitioned from SO ILE because of intolerance. Use of MO ILE allowed an increase in ILE energy from 8% ± 8% to 22% ± 8% while reducing dextrose energy from 66% ± 8% to 54% ± 5%, maintaining stability in alkaline phosphatase and triglyceride levels, and achieving improvement in aspartate aminotransferase, alanine aminotransferase, total bilirubin, and α‐tocopherol levels. Conclusion : In this HPN cohort with SO ILE intolerance, MO ILE was well tolerated and allowed an improvement in macronutrient composition while improving some liver parameters over a 12‐month period.

AbstractFor patients receiving home parenteral nutrition (HPN), vascular access with a central venous catheter (CVC) is essential to safely administer parenteral nutrition (PN) to meet their nutrition and hydration needs. Unfortunately, despite rigorous training and prevention strategies, CVCs are susceptible to complications such as infection, occlusion, thrombosis, and mechanical failure. Much of the published research on CVC complications focuses on infections; however, catheter occlusions and mechanical failures also contribute significantly to catheter dysfunction and loss. Frequent CVC exchanges put HPN patients at risk of loss of vascular access, making it essential that any strategies that can salvage the CVC be implemented prior to removal. CVC repair is 1 technique that can be utilized to avoid CVC exchanges in certain situations. CVC repairs can be performed in the office or on the ward and are cost effective when compared with CVC replacement. When performed by trained clinical staff, the procedures are highly successful and associated with low risk.
