RESUMEN

PURPOSE: Food insecurity is prevalent among low-income immigrant and minority patients with cancer. To our knowledge, this randomized controlled trial is the first to prospectively examine the impact on cancer outcomes of food insecurity interventions, with the goal of informing evidence-based interventions to address food insecurity in patients with cancer. METHODS: A three-arm randomized controlled trial was conducted among food-insecure (18-item US Department of Agriculture Household Food Security Survey Module score ≥ 3) patients with cancer (N = 117) at four New York City safety net cancer clinics. Arms included a hospital cancer clinic-based food pantry (arm 1), food voucher plus pantry (arm 2), and home grocery delivery plus pantry (arm 3). Treatment completion (primary outcome) and full appointment attendance were assessed at 6 months. Food security status, depression symptoms (Patient Health Questionnaire-9), and quality-of-life scores (Functional Assessment of Cancer Therapy-General) were assessed at baseline and at 6 months. RESULTS: Voucher plus pantry had the highest treatment completion rate (94.6%), followed by grocery delivery plus pantry (82.5%) and pantry (77.5%; P = .046). Food security scores improved significantly in all arms, and Patient Health Questionnaire-9 and Functional Assessment of Cancer Therapy-General scores improved significantly in the pantry and delivery plus pantry arms. CONCLUSION: Our findings in this preliminary study suggest that voucher plus pantry was the most effective intervention at improving treatment completion, and it met our a priori criterion for a promising intervention (≥ 90%). All interventions demonstrated the potential to improve food security among medically underserved, food-insecure patients with cancer at risk of impaired nutrition status, reduced quality of life, and poorer survival. All patients with cancer should be screened for food insecurity, with evidence-based food insecurity interventions made available.

RESUMEN

BACKGROUND: Sarcopenia is associated with postoperative complications in inflammatory bowel disease. It has most commonly been defined using the skeletal muscle index, computed after analysis of cross-sectional muscle area at L3. Psoas muscle thickness normalized to height (PMTH), which is easier to derive, is a potential surrogate of SMI and sarcopenia in patients with cirrhosis and chronic pancreatitis. We investigate whether sarcopenia defined by PMTH has utility in predicting post-operative outcomes in patients with inflammatory bowel disease. METHODS: We performed a retrospective study of adults undergoing IBD-related surgery from 2009 to 2019 at two hospitals. Sarcopenia was defined by sex-specific PMTH at the umbilicus on cross-sectional imaging using a 50th percentile median cutoff. Predictive models were created using variables (BMI, age, sex, smoking status, albumin, INR, platelets, hemoglobin, hypertension, diabetes, CAD, medications) that may be associated with complications (mortality, reoperation, readmission, transfusions, ICU admission, infection, DVT/PE), and sarcopenia for comparison. RESULTS: 85 patients with IBD were included. Lower albumin level (OR = 0.52, p = 0.039) and biologic use (OR = 5.92, p = 0.006) were associated with postoperative complications. There was no significant difference using PMTH compared to a model incorporating hypoalbuminemia and biologic use in predicting complications. Sarcopenia on univariate analysis was associated with a lower 30 day rate of reoperation (p = 0.04). CONCLUSIONS: A low status of PMTH was not associated with increased postoperative complications, however hypoalbuminemia and biologic use were. PMTH as a surrogate for sarcopenia requires further study, ideally with prospective studies comparing PMTH with accepted radiographic surrogates for sarcopenia, to determine its role in clinical decision making.

RESUMEN

Background: Inflammatory bowel disease (IBD) care is beset with substantial practice variation. Learning health systems (LHSs) aim to learn from this variation and improve quality of care by sharing feedback and improvement strategies within the LHS. Obtaining accurate information on outcomes and quality of care is a priority for LHS, which often includes patients' self-reported data. While prior work has shown that patients can accurately report their diagnosis and surgical history, little is known about their ability to self-report recent healthcare utilization, medication use, and vaccination status. Methods: We compared patient self-reported data within the IBD Qorus LHS regarding recent IBD-related emergency department (ED) visits, hospitalizations, computerized tomography (CT) scans, corticosteroid use, opioid use, influenza vaccinations, and pneumococcal vaccinations with electronic health record (EHR) data. Results: We compared 328 patient self-reports to data extracted from the EHR. Sensitivity was moderate-to-high for ED visits, hospitalizations, and CT scans (76%, 87%, and 87%, respectively), sensitivity was lower for medication use with 71% sensitivity for corticosteroid use and only 50% sensitivity for self-reported use of opioids. Vaccinations were reported with high sensitivity, but overall agreement was low as many patients reported vaccinations that were not registered in the EHR. Conclusions: Self-reported IBD-related ED visits, hospitalizations, and CT scans are reported with high sensitivity and accuracy. Medication use, and in particular opioid use, is less reliably reported. Vaccination self-report is likely more accurate than EHR data as many vaccinations are not accurately registered.

RESUMEN

PURPOSE: Racial/ethnic minorities experience greater job loss than whites during periods of economic downturn and after a cancer diagnosis. Therefore, race/ethnicity-matched controls are needed to distinguish the impact of illness on job loss from secular trends METHODS: Surveys were administered during and 4-month post-completion of breast cancer treatment. Patients were pre-diagnosis employed women aged 18-64, undergoing treatment for stage I-III breast cancers, who spoke English, Chinese, Korean, or Spanish. Each patient was asked to: (1) nominate peers who were surveyed in a corresponding timeframe (active controls), (2) report a friend's work status at baseline and follow-up (passive controls). Both types of controls were healthy, employed at baseline, and shared the nominating patient's race/ethnicity, language, and age. The primary outcome was number of evaluable patient-control pairs by type of control. A patient-control pair was evaluable if work status at follow-up was reported for both individuals. RESULTS: Of the 180 patients, 25% had evaluable active controls (45 patient-control pairs); 84% had evaluable passive controls (151 patient-control pairs). Although patients with controls differed from those without controls under each strategy, there was no difference in the percentage of controls who were working at follow-up (96% of active controls; 91% of passive controls). However, only 65% of patients were working at follow-up. CONCLUSIONS: The majority of patients had evaluable passive controls. There was no significant difference in outcome between controls ascertained through either method IMPLICATIONS FOR CANCER SURVIVORS: Passive controls are a low-cost, higher-yield option to control for secular trends in racially/ethnically diverse samples.

RESUMEN

PURPOSE: Inflammatory bowel disease (IBD) patients experience diverse symptoms and the impact of these different symptoms varies substantially. Current disease activity measures do not account for the relative importance of the different symptoms and severity levels. In this study, we aimed to quantify the relative importance of different symptoms for IBD patients and to develop a patient preference-weighted symptom (PWS) score to assess symptom burden in IBD. METHODS: We performed a choice-based conjoint analysis (CBCA) survey with 129 IBD patients to estimate the relative importance of four common IBD symptoms: stool frequency, abdominal pain, blood in stools, and urgency. We then developed the PWS score using the preferences obtained from the CBCA, which we validated against existing measures. RESULTS: CBCA revealed that urgency was the most important symptom to patients, followed by abdominal pain and blood in stools. Urgency associated with incontinence received particularly high scores and was perceived to be more than 3 times as important as urgency without incontinence. Our results confirmed that different symptoms are not equally bothersome, and we showed that the relation between symptom-level and importance is not linear. The PWS score, which we developed using these estimates was highly correlated with existing disease activity measures. CONCLUSIONS: We quantified the relative importance of four common IBD symptoms and developed the PWS score for IBD, which takes the relative importance of different symptoms and symptom-levels into account. The PWS score can be used to obtain a patient-centered assessment of symptom burden.

RESUMEN

In response to elevated temperatures, plants alter the activities of enzymes that affect lipid composition. While it has long been known that plant leaf membrane lipids become less unsaturated in response to heat, other changes, including polygalactosylation of galactolipids, head group acylation of galactolipids, increases in phosphatidic acid and triacylglycerols, and formation of sterol glucosides and acyl sterol glucosides, have been observed more recently. In this work, by measuring lipid levels with mass spectrometry, we confirm the previously observed changes in Arabidopsis thaliana leaf lipids under three heat stress regimens. Additionally, in response to heat, increased oxidation of the fatty acyl chains of leaf galactolipids, sulfoquinovosyldiacylglycerols, and phosphatidylglycerols, and incorporation of oxidized acyl chains into acylated monogalactosyldiacylglycerols are shown. We also observed increased levels of digalactosylmonoacylglycerols and monogalactosylmonoacylglycerols. The hypothesis that a defect in sterol glycosylation would adversely affect regrowth of plants after a severe heat stress regimen was tested, but differences between wild-type and sterol glycosylation-defective plants were not detected.

RESUMEN

STUDY OBJECTIVE: Ustekinumab was recently approved by the United States U.S. Food and Drug Administration for the treatment of Crohn's disease. In this analysis, we aimed to compare the cost-effectiveness of ustekinumab, infliximab, or adalimumab for the treatment of moderate-severe Crohn's disease in patients who failed conventional therapy (i.e., corticosteroids and immunomodulators) but were naïve to tumor necrosis factor antagonists (i.e., biologic drugs). DESIGN: Cost-effectiveness analysis using a hybrid model structure (decision tree and Markov model). MEASUREMENTS AND MAIN RESULTS: A decision tree simulated biologic induction, and a Markov model simulated biologic and conventional therapy maintenance. Cycle length was 2 weeks with a discounted 5-year time horizon and a limited U.S. societal perspective in the base case; results from a payer perspective are also reported. Transition probabilities, direct costs, indirect costs, and utilities were obtained from the literature. To measure relative treatment value (i.e., order of treatment cost-effectiveness), net monetary benefits were reported for a $150,000 willingness-to-pay threshold per quality-adjusted life-year in the base case. Infliximab dominated both adalimumab and ustekinumab, with a net monetary benefit (NMB) of $9943 and $29,798, respectively, in the base case. Adalimumab dominated ustekinumab, with an NMB of $19,855. All biologics yielded similar quality-adjusted life-years (~3.5), whereas costs varied substantially ($50,510, $54,985, and $72,921 for infliximab, adalimumab, and ustekinumab, respectively). The payer perspective, alternate time horizons, and scenario analyses consistently showed infliximab dominance. One-way, threshold, and probabilistic sensitivity analyses confirmed the robustness of these results with respect to all parameters. Although biosimilars were not explicitly modeled as comparators, one-way sensitivity analysis showed that drug acquisition costs could alter relative treatment value but would have to be varied by at least 50%. CONCLUSION: For moderate-severe Crohn's disease, infliximab yields significantly more NMBs compared with both adalimumab and ustekinumab. Additional clinical (e.g., empiric dosing, biologic cycling) and quality-of-life (e.g., lost productivity, disutility of home injections) research is needed to allow for model frameworks and parameters that more accurately reflect the nuances of Crohn's disease treatment.

RESUMEN

Background: Tumor necrosis factor alpha-induced protein 3 (TNFAIP3) is a multifunctional ubiquitin binding and editing enzyme that regulates inflammation. Genetic studies have implicated polymorphisms within the TNFAIP3 locus to the development of numerous immune-related diseases. This study evaluated the frequencies of single nucleotide polymorphism (SNPs) within the exonic regions of the TNFAIP3 gene and an associated point mutation from the Illumina array among a predominantly Hispanic cohort. Methods: Genomic DNA was obtained from 721 participants and sequencing of all TNFAIP3 exons and an intergenic point mutation (rs6920220) was performed. In vitro functional assessment was performed by transfecting mutated TNFAIP3 constructs into TNFAIP3 knockout cells containing the NF-kB luciferase reporter and stimulating with TNFα. Comparative statistics were performed with Student's t-test for continuous variables and Chi-squared test for categorical variables. Results: Sequencing revealed two missense SNPs, rs146534657:A>G and rs2230926:T>G, both within exon 3 of TNFAIP3, which encodes the protein's deubiquitinating enzymatic domain. Frequencies of all three point mutations differed significantly across racial groups (χ2-test, P=0.014 to P<0.001). Compared to Caucasians, rs146534657:A>G was overrepresented among Hispanics (odds ratio (OR) [95% CI] 4.05 [1.24-13.18]), and rs2230926:T>G was more prevalent among African Americans (OR [95% CI] 3.65 [1.58-8.43]). In vitro assays confirm rs146534657:A>G and rs2230926:T>G decrease the ability of TNFAIP3 to abrogate NF-κB activation by 2-fold (P<0.01) and 1.7-fold (P<0.01), respectively. Conclusions: This study reports the frequency of rs146534657:A>G among Hispanics and is the first to evaluate its potential physiologic impact, establishing a basis for future research as a potential biomarker among this population.

RESUMEN

BACKGROUND: Women with chronic inflammatory diseases face uncertainty regarding the safety of biologics during breast feeding. CRADLE was the first industry-sponsored study to evaluate certolizumab pegol (CZP) concentrations in human breast milk and estimate average daily infant dose (ADID) of maternal CZP. METHODS: CRADLE (NCT02154425) was a pharmacokinetic study of lactating mothers receiving CZP. After ≥3 CZP doses, breast milk samples were collected across one dosing period (14 days for 200 mg every 2 weeks [Q2W]; 28 days for 400 mg every 4 weeks [Q4W]). Optimal analytical methods were developed to determine CZP and polyethylene glycol (PEG) levels in breast milk. ADID and relative infant dose (RID) were estimated. Safety events in mothers and infants were assessed. RESULTS: 19 CZP-treated mothers were screened; 17 entered the sampling period: 16 on 200 mg Q2W, 1 on 400 mg Q4W. 77/137 (56%) breast milk samples had no measurable CZP. For 4/17 mothers, all samples were below the lower limit of quantification (LLOQ). Estimated ADID was 0-0.0104 mg/kg/day; median RID: 0.15%. PEG was undetectable in 134/137 samples (results could not be determined in three samples). Infants of CZP-exposed mothers had a safety profile consistent with that of unexposed similar-age infants. CONCLUSION: When quantifiable, CZP concentrations were <3× LLOQ (<1% plasma concentration observed with therapeutic dose), indicating no/minimal CZP transfer from plasma to breast milk. RID was 0.15% of maternal dose; <10% is considered unlikely to be of clinical concern. No PEG transfer was observed. CZP absorption by infants via breast milk is unlikely due to its low oral bioavailability and Fc--free molecular structure. These findings are reassuring and support continuation of CZP treatment during breast feeding. TRIAL REGISTRATION NUMBER: NCT02154425; Results.

RESUMEN

BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is one of the thrombotic microangiopathic (TMA) syndromes, caused by severely reduced activity of the vWF-cleaving protease ADAMTS13. Systemic lupus erythematosus (SLE), on the other hand, is an autoimmune disease that affects various organs in the body, including the hematopoietic system. SLE can present with TMA, and differentiating between SLE and TTP in those cases can be very challenging, particularly in patients with no prior history of SLE. Furthermore, an association between these 2 diseases has been described in the literature, with most of the TTP cases occurring after the diagnosis of SLE. In rare cases, TTP may precede the diagnosis of SLE or occur concurrently. CASE REPORT We present a case of a previously healthy 34-year-old female who presented with dizziness and flu-like symptoms and was found to have thrombocytopenia, hemolytic anemia, and schistocytes in the peripheral smear. She was subsequently diagnosed with TTP and started on plasmapheresis and high-dose steroids, but without a sustained response. A diagnosis of refractory TTP was made, and she was transferred to our facility for further management. Initially, the patient was started on rituximab, but her condition continued to deteriorate, with worsening thrombocytopenia. Later, she also fulfilled the Systemic Lupus International Collaborating Clinics (SLICC) criteria for diagnosis of SLE. Treatment of TTP in SLE patients is generally similar to that in the general population, but in refractory cases there are few reports in the literature that show the efficacy of cyclophosphamide. We started our patient on cyclophosphamide and noticed a sustained improvement in the platelet count in the following weeks. CONCLUSIONS Thrombotic thrombocytopenic purpura is a life-threatening hematological emergency which must be diagnosed and treated in a timely manner. Refractory cases of TTP have been described in the literature, but without clear evidence-based guidelines for its management, and is solely based on expert opinion and previous case reports. Further studies are needed to establish guidelines for its management. We present this case to highlight the role that cyclophosphamide might carry in those cases and to be a foundation for these future studies.

RESUMEN

BACKGROUND: Malnutrition is common in inflammatory bowel disease (IBD). Identifying patients who are malnourished or at risk for malnutrition may lead to early intervention and improve patient outcomes. To date, little is known about the role of nutritional assessment and management in IBD care. We aimed to evaluate knowledge, attitudes, and beliefs regarding nutrition in IBD among patients and providers. METHODS: Surveys were mailed electronically to patients and providers identified through their membership in the Crohn's & Colitis Foundation of America. In addition, patient and provider focus groups were conducted to explore nutrition-related themes. These surveys and focus groups were designed to evaluate knowledge and perceived importance of nutrition, patient-provider interactions regarding nutrition and use of nutritional resources. RESULTS: There were 223 provider respondents (65.5% gastroenterologists, 15.2% nurses, and 6.7% dietitians). Forty-one percent of the gastroenterologists rated their knowledge of nutrition in IBD as "very good" compared with 87% of dietitians and 16% of nurses (P < 0.001). Thirty-three percent of the gastroenterologists reported not routinely screening their IBD patients for malnutrition. The patient survey had 567 respondents with 27% rating their knowledge of nutrition in IBD as "very good." In the focus groups, a lack of adequate IBD nutritional resources was evident along with a desire for improved access to nutrition specialists. CONCLUSIONS: Significant gaps in knowledge relating to nutrition in IBD seem to exist. Targeted educational initiatives and improved access to nutritional experts are warranted. In addition, a standardized process for the assessment of malnutrition among patients with IBD should be developed.

RESUMEN

OBJECTIVES: Pancreatic intraepithelial neoplasia (PanIN), thought to represent the dominant precursor of pancreatic adenocarcinoma (PDAC), is often found synchronously adjacent to resected PDAC tumors. However, its prognostic significance on outcome after PDAC resection is unknown. METHODS: A total of 342 patients who underwent resection for PDAC between 2005 and 2010 at a single institution were identified and stratified according to highest grade of PanIN demonstrated surrounding the tumor. Clinical and pathologic characteristics of each patient and tissue were recorded and analyzed. The primary outcome was length of survival after resection. RESULTS: An absence of PanIN lesions was identified in 32 patients (9%), low grade PanIN without synchronous high grade lesions was identified in 52 patients (15%), and high grade PanIN was found in 258 patients (75%). Median survival were 12.8 months for the non-PanIN group, 26.3 months for the low-grade PanIN group, and 23.8 months for the high-grade PanIN groups (P = 0.043). In multivariable analysis, absence of PanIN was independently associated with poor survival (P = 0.002). CONCLUSIONS: The patients who demonstrate an absence of PanIN in the pancreatic tissue adjacent to the resected PDAC tumor have shorter postresection survival compared with those who demonstrate a PanIN lesion.

RESUMEN

BACKGROUND: Approximately 10% of pancreatic ductal adenocarcinoma (PDAC) is due to a genetic predisposition, including the breast and ovarian cancer syndrome germline mutations BRCA1 and BRCA2. Knowledge of specific genetic mutations predisposing to PDAC may enable risk stratification, early detection, and the development of effective screening and surveillance programs. In the current study, the authors attempted to determine the diagnostic yield of testing for BRCA1/2 germline mutations in a PDAC screening cohort and a PDAC cohort referred for genetic testing. METHODS: Patients in a high-risk PDAC prevention and genetics program or those with a personal history of PDAC who were referred for genetic evaluation underwent testing for BRCA1/2 germline mutations. Clinical BRCA1/2 genetic testing included testing for the 3 Ashkenazi Jewish founder mutations or BRCA1/2 comprehensive testing. RESULTS: A total of 37 patients without PDAC underwent BRCA1/2 testing at the study institution. Genetic testing identified 7 patients who were BRCA1/2 carriers for a yield of 18.9%. Six patients carried Ashkenazi Jewish founder mutations (3 with BRCA1 and 3 with BRCA2), and 1 patient was found to have a BRCA2 mutation on comprehensive testing. Thirty-two patients with PDAC underwent BRCA1/2 genetic testing. Five patients had Ashkenazi Jewish founder mutations (2 with BRCA1 and 3 with BRCA2), and 2 patients were found to have BRCA2 mutations on comprehensive testing. The diagnostic yield was 7 of 32 patients (21.9%). CONCLUSIONS: BRCA1/2 testing is useful in PDAC risk stratification and alters risk assignment and screening recommendations for mutation-positive patients and their families. Clinical BRCA1/2 testing should be considered in patients of Ashkenazi Jewish descent with a personal history or family history of PDAC, even in the absence of a family history of breast and ovarian cancer.

RESUMEN

The evolving understanding of the role of the microbiome and environmental factors in the pathogenesis of inflammatory bowel disease makes diet an interesting and potentially powerful tool in the treatment of disease. However, at this time, evidence is limited but anecdotal reports of success abound. There is a bewildering array of new diets being tried by patients in an attempt to control diseases. This review attempts to summarize the most common diets for the treating physician.

RESUMEN

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) is associated with the breast ovarian cancer syndrome (BRCA1/BRCA2) mutations. It is unknown if this association is causal. EXPERIMENTAL DESIGN: This is a single-site study of patients who underwent surgical pancreatic tumor resection and self-identified as Ashkenazi Jewish. DNA from normal pancreatic tissue was genotyped for the three Ashkenazi Jewish BRCA1/2 founder mutations BRCA1 185delAG, BRCA1 5382insC, and BRCA2 6174delT, and loss of heterozygosity (LOH) was determined by sequencing DNA from microdissected tumor. When additional tumor tissue was available, p53 immunohistochemistry (IHC) was conducted. RESULTS: Thirty-seven patients underwent surgery for PDAC, seven for intraductal papillary mucinous neoplasm (IPMN), and 19 for other diseases. A high prevalence of BRCA1/2 mutations was found in the surgical cohort (12/63; 19.0%; P < 0.001), PDAC cohort (8/37; 21.6%; P < 0.001), and IPMN cohort (2/7; 28.6%; P = .01) compared with published control mutation frequency. A high prevalence of BRCA1 185delAG (8.1%; P < 0.001) and BRCA2 6174delT (10.8%; P < 0.001) in Ashkenazi Jewish patients with PDAC was shown. BRCA1/2 LOH was found in 2 of 4 BRCA1-associated PDACs and 3 of 4 BRCA2-associated PDACs. Positive p53 IHC was found in 5 of 8 BRCA1/2 PDACs. CONCLUSIONS: We show a high prevalence of BRCA1/2 mutations with LOH in an Ashkenazi Jewish cohort of surgically resected PDAC and neoplastic lesions, suggesting that these germline mutations are causal in selected individuals.

RESUMEN

Inflammatory bowel disease (IBD) has classically been associated with malnutrition and weight loss, although this has become less common with advances in treatment and greater proportions of patients attaining clinical remission. However, micronutrient deficiencies are still relatively common, particularly in CD patients with active small bowel disease and/or multiple resections. This is an updated literature review of the prevalence of major micronutrient deficiencies in IBD patients, focusing on those associated with important extraintestinal complications, including anemia (iron, folate, vitamin B12) bone disease (calcium, vitamin D, and possibly vitamin K), hypercoagulability (folate, vitamins B6, and B12), wound healing (zinc, vitamins A and C), and colorectal cancer risk (folate and possibly vitamin D and calcium).
