Hospitalization of Patients With Diabetes Due to Ketoacidosis Before and After the Initiation of Sodium-Glucose Cotransporter-2 Inhibitors.

OBJECTIVE: Diabetic ketoacidosis (DKA) is a rare side effect related to sodium-glucose cotransporter-2 inhibitors (SGLT2I). This study investigated the incidence of people with diabetes hospitalized because of DKA after the implementation of SGLT2I (2015-2019), compared with the pre-SGLT2I era. METHODS: In this retrospective cohort study, medical records of all adult patients hospitalized with a diagnosis of DKA in a tertiary referral center from 2011-2019 were reviewed. The incidence of DKA was compared between the periods 2011-2014 and 2015-2019. Demographic and clinical data of patients hospitalized with DKA as well as SGLT2I use were extracted. RESULTS: During 2011-2019, there were 186 hospitalizations because of DKA. The rate of hospitalization was stable during 2011-2019 at 0.22% ± 0.04% (95% CI, 0.18-0.25). The clinical characteristics of people hospitalized with DKA in 2011-2014 were similar to those of people hospitalized during 2015-2019. Only 7 people (6.1%) in the 2015-2019 cohort had SGLT2I-related DKA, and their clinical characteristics were similar to those of the rest of the cohort. CONCLUSIONS: The rate of hospitalizations because of DKA remained stable before and 5 years after SGLT2I were implemented for the treatment of type 2 diabetes mellitus. Larger, multi-institutional studies with longer follow-ups are needed to study the effect of SGLT2I on the rate of hospitalizations because of DKA among people with diabetes. Although DKA events associated with SGLT2I are rare, they should be strongly considered in the differential diagnosis of people treated with these medications.

Influence of Fasting until Noon (Extended Postabsorptive State) on Clock Gene mRNA Expression and Regulation of Body Weight and Glucose Metabolism.

The trend of fasting until noon (omission or delayed breakfast) is increasingly prevalent in modern society. This eating pattern triggers discordance between endogenous circadian clock rhythms and the feeding/fasting cycle and is associated with an increased incidence of obesity and T2D. Although the underlying mechanism of this association is not well understood, growing evidence suggests that fasting until noon, also known as an "extended postabsorptive state", has the potential to cause a deleterious effect on clock gene expression and to disrupt regulation of body weight, postprandial and overall glycemia, skeletal muscle protein synthesis, and appetite, and may also lead to lower energy expenditure. This manuscript overviews the clock gene-controlled glucose metabolism during the active and resting phases and the consequences of postponing until noon the transition from postabsorptive to fed state on glucose metabolism, weight control, and energy expenditure. Finally, we will discuss the metabolic advantages of shifting more energy, carbohydrates (CH), and proteins to the early hours of the day.

[THE SERUM LEVELS OF MILK AND PEANUT-SPECIFIC IGE: ROLE IN THE EVALUATION OF THE RISK FOR ALLERGIC REACTION IN CHILDREN IN ISRAEL].

BACKGROUND: The performance characteristics of the ImmunoCAP assay for detecting specific IgE antibodies in the evaluation of milk and peanut allergy have been established. However, the results are not comparable to the IMMULITE 2000, another FDA-approved assay available in Israel, owing to differences in the extracts used, technical method, and population studied. OBJECTIVES: To establish the performance characteristics and predictive values for the IMMULITE 2000 assay in Israel. METHODS: The database of the Allergy Clinic at Schneider Children's Medical Center in Israel was searched for all patients referred for evaluation of allergies in 2006-2009. The results of the milk- and peanut-specific IgE antibody tests were collected and correlated with the clinical diagnoses of milk and peanut allergy or tolerance. Sensitivity, specificity and positive and negative predictive values were calculated as well as receiver operating characteristic (ROC) plots. RESULTS: The prevalence of milk allergy was 30% (111/369 patients), and peanut allergy, 6% (31/505 patients). The area under the ROC curve was 0.954 for milk allergy and 0.956 for peanut allergy. The levels with a positive predictive value of ≥95% were 10 kU/L and 3 kU/L, respectively. The level of peanut-specific IgE antibodies with a ≥95% positive predictive value was lower than found for the ImmunoCAP in the USA and Europe. CONCLUSIONS: These findings indicate that the decision points used for predicting the risk of future allergic reactions must be calculated separately for different assay methods and different populations. Our findings may assist the allergists in Israel to decide whether to perform a supervised oral challenge in order to verify if the patient has developed tolerance to milk or peanuts.

Clinical characteristics of a large familial cohort with Medullary thyroid cancer and germline Cys618Arg RET mutation in an Israeli multicenter study.

Objective: To determine genealogical, clinical and pathological characteristics of a cohort with Cys618Arg mutation from an Israeli multicenter MTC study. Methods: Retrospective database analysis examining RET mutations and comparing Cys618Arg and Cys634Arg/Thr/Tyr subgroups. Results: Genetic testing was performed in 131/275 MTC patients (47.6%). RET mutations were found in 50/131 (38.2%), including Cys618Arg (28/50 cases,56%), and Cys634Arg/Thr/Tyr (15/50,30%). Through genealogical study, 31 MTC patients were found descendants of one family of Jewish Moroccan descent, accounting for 27/28 patients with documented Cys618Arg mutation and 4 patients without available genetic testing. Familial Cys618Arg cases (n=31) and Cys634Arg/Thr/Tyr cases (n=15, from 6 families) were compared. Although surgical age was similar (25.7 vs 31.3 years, p=0.19), the Cys618Arg group had smaller tumors (8.9mm vs 18.5mm, p=0.004) and lower calcitonin levels (33.9 vs 84.5 X/ULN, p=0.03). Youngest ages at MTC diagnosis were 8 and 3 years in Cys618Arg and Cys634Arg/Thr/Tyr cohorts, respectively. Long-term outcome was similar between groups. The Cys618Arg cohort had lower rates of pheochromocytoma (6.5% vs 53.3%, p=0.001) and primary hyperparathyroidism (3.2% vs 33.3%, p=0.01). Conclusion: This is the first description of RET mutation distribution in Israel. Of 131 tested MTC patients, Cys618Arg was the predominant mutation. To the best of our knowledge, this is the largest cohort of Cys618Arg mutation described. For Cys618Arg and Cys634Arg/Thr/Tyr cohorts, MTC was diagnosed earlier than expected, likely due to familial genetic screening, and MTC outcomes were similar between groups. International studies are necessary to further characterize the clinical features of Cys618 mutations due to their relative rarity.

Clinical and pathologic characteristics of appendiceal neuroendocrine neoplasms diagnosed during pregnancy.

Introduction: Although appendicitis occurs in approximately 1:1000 pregnancies, appendiceal neuroendocrine neoplasm (ANEN) diagnosis during pregnancy is very rare. Data on presentation, treatment and prognosis is scarce. Aim: To describe ANEN cases diagnosed during pregnancy. Materials and methods: A retrospective appraisal of 7 consecutive ANEN patients diagnosed during pregnancy from four Israeli tertiary medical centers and comparison with 17 cases described in the literature from 1965-2021. Results: Age at ANEN diagnosis was 26.4 ± 3.5 years (range 21-33). Patients were diagnosed between gestational weeks 6-40, most frequently in the third trimester (53%). The most common presenting symptom was abdominal pain. Tumor size was 14.3 ± 8.9mm (range 3-45mm). In patients from our series appendiceal base involvement was reported in 2/7; mesoappendiceal invasion in 5/7; lympho-vascular invasion in 2/7. Ki67 staining was reported in 6/7 cases and ranged from 1-10%. Pathology details were lacking in most of the previously published cases. All 7 pregnancies in our series resulted in term delivery with no complications, whereas in historical cases there were one first trimester abortion, one ectopic pregnancy, and one stillbirth. Right hemicolectomy was performed in 5/7 patients in our series and reported in 2/17 historical cases. All hemicolectomies were performed after delivery, 3-16 months after appendectomy. Local metastases were reported in two cases. Follow-up duration was 7-98 months for our patients and 3-48 months in 5 historical cases. No disease recurrence, distant metastases or mortality were noted. Conclusions: To the best of our knowledge, this is the largest series describing the extremely rare diagnosis of ANEN during pregnancy. Although pathologic characteristics varied, pregnancy outcomes were usually favorable and long-term prognosis was excellent. This data may suggest that a conservative approach to patients with ANEN diagnosis during pregnancy can be considered.

National Survey Using CFIR to Assess Early Outpatient Specialty Palliative Care Implementation.

CONTEXT: The American Society of Clinical Oncology (ASCO) recommends that outpatient specialty palliative care (OSPC) be offered within eight weeks of an advanced cancer diagnosis. To meet the rising demand, there has been an increase in the availability of OSPC services at National Cancer Institute (NCI)-designated cancer centers; however, many OSPC referrals still occur late in the disease course. OBJECTIVES: Using the Consolidated Framework for Implementation Research (CFIR), we evaluated facilitators and barriers to early OSPC implementation and associated clinic characteristics. METHODS: We selected relevant CFIR constructs for inclusion in a survey that was distributed to the OSPC clinic leader at each NCI-designated cancer center. For each statement, respondents were instructed to rate the degree to which they agreed on a five-point Likert scale. We used descriptive statistics to summarize responses to survey items and explore differences in barriers based on OSPC clinic size and maturity. RESULTS: Of 60 eligible sites, 40 (67%) completed the survey. The most commonly agreed upon barriers to early OSPC included inadequate number of OSPC providers (73%), lack of performance metric goals (65%), insufficient space to deliver early OSPC (58%), logistical challenges created by early OSPC (55%), and absence of formal interdisciplinary communication systems (53%). The most frequently reported barriers differed according to clinic size and maturity. CONCLUSION: Most barriers were modifiable in nature and related to the "Inner Setting" domain of the CFIR, which highlights the need for careful strategic planning by leadership when implementing early OSPC.

Institution of Standardized Consultation Criteria to Increase Early Palliative Care Utilization in Older Patients With Acute Leukemia.

PURPOSE: Older patients with acute leukemia (AL) have a high symptom burden and poor prognosis. Although integration of palliative care (PC) with oncologic care has been shown to improve quality-of-life and end-of-life care in patients with AL, the malignant hematologists at our tertiary care hospital make limited use of PC services and do so late in the disease course. Using the Plan-Do-Study-Act (PDSA) methodology, we aimed to increase early PC utilization by older patients with newly diagnosed AL. METHODS: We instituted the following standardized criteria to trigger inpatient PC consultation: (1) age 70 years and older and (2) new AL diagnosis within 8 weeks. PC consultations were tracked during sequential PDSA cycles in 2021 and compared with baseline rates in 2019. We also assessed the frequency of subsequent PC encounters in patients who received a triggered inpatient PC consult. RESULTS: The baseline PC consultation rate before our intervention was 55%. This increased to 77% and 80% during PDSA cycles 1 and 2, respectively. The median time from diagnosis to first PC consult decreased from 49 days to 7 days. Among patients who received a triggered PC consult, 43% had no subsequent inpatient or outpatient PC encounter after discharge. CONCLUSION: Although standardized PC consultation criteria led to earlier PC consultation in older patients with AL, it did not result in sustained PC follow-up throughout the disease trajectory. Future PDSA cycles will focus on identifying strategies to maintain the integration of PC with oncologic care over time, particularly in the ambulatory setting.

Is there an added value for whole body scan combined with stimulated thyroglobulin testing for follow-up of differentiated thyroid cancer patients?

AIM: The aim of this study was to evaluate the incidence of positive WBS in patients with negative stimulated thyroglobulin (sTg), to define the clinical characteristics of this group, and the association with disease outcome. METHODS: DTC patients who underwent surveillance with simultaneous sTg and WBS were included. RESULTS: Two hundred seventy-two patients were included. Age at diagnosis was 46.5 ± 15.2 years, 79% were female. Mean duration of follow-up was 11.6 ± 6.8 years. Patients were categorised according to stimulation test results: sTg(-)/WBS(-) in 192/272 (70.6%); sTg(+) regardless of WBS results in 33/272 (12.1%); and sTg(-)/WBS(+) in 47/272 (17.3%) subjects. sTg > 10 mg/dl was considered positive. The three groups had similar demographic and pathologic characteristics. During follow-up, additional treatment was given in 77 patients (28.3%). Twelve (4.4%) developed distant metastases; 16 patients (5.8%) died. No deaths were disease-related. There was no difference in mortality rate between categories (P = 0.182). On multivariate analysis, additional treatment was associated with male gender (P = 0.046) and positive stimulation test results, either sTg (P < 0.001) or WBS (P < 0.001). Of the 47 WBS(+)/sTg(-) patients, 7(15%) were treated due to positive WBS results, including two who underwent additional surgery. CONCLUSION: A substantial proportion of stimulation test results were discordant. There was a significant association between WBS results and administration of additional treatment. Routine WBS had additional value for a small proportion of patients with no other evidence for disease and no indication for WBS.

Efficacy and Safety of Intravenous Pamidronate for Parathyroid Hormone-dependent Hypercalcemia in Hospitalized Patients.

CONTEXT: Bisphosphonates are effective for hypercalcemia of malignancy (HOM). Efficacy and safety data for bisphosphonates in parathyroid hormone-related hypercalcemia (PTHRH) are rare, including pamidronate (Pam), which is not indicated for this condition. OBJECTIVE: This work aims to evaluate the efficacy and safety of Pam for moderate-to-severe PTHRH. METHODS: This retrospective case-control study was conducted at a tertiary care medical center. Patients included adults hospitalized with serum calcium levels greater than 12 mg/dL, from October 29, 2013 to December 17, 2019. Etiology was categorized as PTHRH or PTH-independent. Clinical and laboratory data of PTHRH patients treated with Pam (PTHRH-Pam+) were compared to Pam-untreated counterparts (PTHRH-Pam-). RESULTS: Thirty-four patients with 37 hospitalizations for PTHRH (Pam-treated and -untreated) met the inclusion criteria. Pam was given in 24 of 37 cases (64.8%). Admission serum calcium levels for the PTHRH-Pam+ group were higher than for PTHRH-Pam- group (14.4 mg/dL vs 13.0 mg/dL, P = .005). Median total Pam dose was 60 mg (range, 30-180 mg) in the treated group. Serum calcium decreased 3.5 mg/dL for PTHRH-Pam+ vs 1.6 mg/dL for PTHRH-Pam- (P = .003). No PTHRH-Pam+ patients developed hypocalcemia or acute kidney injury. Nadir serum phosphorus levels were lower in the PTHRH-Pam+ vs PTHRH-Pam- group (1.7 mg/dL vs 2.4 mg/dL, respectively, P = .004). Three PTHRH-Pam+ patients developed severe hypophosphatemia; all resolved with intravenous and oral supplementation. Seventeen patients underwent parathyroidectomy, of whom 10 received Pam within 28 days preoperatively. Postoperatively, 4 developed hypocalcemia and 3 hypophosphatemia. CONCLUSION: This study demonstrates that Pam is effective and safe for treating PTHRH, while ensuring close laboratory monitoring of calcium and phosphorus metabolism. Larger, prospective studies are needed to establish the role of Pam and other potent bisphosphonates in moderate-to-severe PTHRH.

Temporal trends in incidence, evaluation and management of neuroendocrine neoplasms of the appendix: 14 years' experience.

BACKGROUND: Information regarding temporal trends in appendiceal neuroendocrine neoplasms (ANEN) is limited. This retrospective study evaluated temporal trends in ANEN incidence and management over a 14-year period. METHODS: Appendectomy pathology reports from a single tertiary center were reviewed. RESULTS: During 2005-2018, 8327 appendectomies were performed and 57 ANENs were diagnosed (average age 31.7 ± 17 years; 70.2% women; 17.5% Arab ethnicity; and 22.8% < 18 years of age). The cohort was divided according to year of diagnosis (Period A 2005-2011; Period B 2012-2018). No differences were found in ANEN incidence (0.75% and 0.62%, respectively, p = 0.104), epidemiologic or pathologic characteristics between periods. In period B, pathology reports were more comprehensive and use of specific imaging and biochemical studies was more prevalent. Hemicolectomy rates and results were similar (8 in Period A, 7 in Period B, p = 0.925). All patients remained alive for the duration of follow-up. CONCLUSIONS: No temporal changes in epidemiological, clinical or pathological features of ANENs were noted. Although clinico-pathological evaluation was more detailed after 2011, there was no change in rates of hemicolectomy or disease prognosis.

Appendiceal tumor incidence and an in-depth look at appendiceal neuroendocrine neoplasm in a cohort of 8,162 appendectomies: Full dataset.

Data describing appendiceal tumor incidence and epidemiology is limited. We collated data from appendectomy pathology reports between 2005 and 2018 in our institution and examined patient epidemiological and appendectomy pathological features [1]. Overall, 8,328 appendectomies were performed at our institution over the pre-specified time period and 8,162 patients had sufficient epidemiological data to be included in the analysis. A total of 153 patients (1.9%) were diagnosed with appendiceal tumors, of which 57 (37.3%) were Appendiceal Neuroendocrine Neoplasm (ANEN), 35 (22.9%) were mucinous cystadenoma and 34 (22.2%) ovarian cancer metastases. We further examined the ANEN cases in order to characterize initial patient and tumor characteristics, to evaluate the performance of further investigations and interventions, and ultimately to study the behavior of these tumors over time.

Lynch Syndrome-Associated Variants and Cancer Rates in an Ancestrally Diverse Biobank.

PURPOSE: Limited data are available on the prevalence and clinical impact of Lynch syndrome (LS)-associated genomic variants in non-European ancestry populations. We identified and characterized individuals harboring LS-associated variants in the ancestrally diverse BioMe Biobank in New York City. PATIENTS AND METHODS: Exome sequence data from 30,223 adult BioMe participants were evaluated for pathogenic, likely pathogenic, and predicted loss-of-function variants in MLH1, MSH2, MSH6, and PMS2. Survey and electronic health record data from variant-positive individuals were reviewed for personal and family cancer histories. RESULTS: We identified 70 individuals (0.2%) harboring LS-associated variants in MLH1 (n = 12; 17%), MSH2 (n = 13; 19%), MSH6 (n = 16; 23%), and PMS2 (n = 29; 41%). The overall prevalence was 1 in 432, with higher prevalence among individuals of self-reported African ancestry (1 in 299) than among Hispanic/Latinx (1 in 654) or European (1 in 518) ancestries. Thirteen variant-positive individuals (19%) had a personal history, and 19 (27%) had a family history of an LS-related cancer. LS-related cancer rates were highest in individuals with MSH6 variants (31%) and lowest in those with PMS2 variants (7%). LS-associated variants were associated with increased risk of colorectal (odds ratio [OR], 5.0; P = .02) and endometrial (OR, 30.1; P = 8.5 × 10-9) cancers in BioMe. Only 2 variant-positive individuals (3%) had a documented diagnosis of LS. CONCLUSION: We found a higher prevalence of LS-associated variants among individuals of African ancestry in New York City. Although cancer risk is significantly increased among variant-positive individuals, the majority do not harbor a clinical diagnosis of LS, suggesting underrecognition of this disease.

Predictors of Recurrence and Survival in Patients With Surgically Resected Pancreatic Neuroendocrine Tumors.

OBJECTIVE: Given the lack of consensus on surveillance guidelines after pancreatic neuroendocrine tumor (PanNET) resection, we assessed outcomes in a large cohort of patients with nonmetastatic, surgically resected PanNETs. METHODS: Data of patients with PanNETs resected between 1990 and 2017 were retrospectively collected using databases at 3 academic institutions. The National Death Index was queried to determine vital status. Kaplan-Meier analysis was used to estimate recurrence-free survival (RFS) and disease-specific survival (DSS) rates. Variables associated with recurrence and disease-related death were identified through Cox multivariate analyses. RESULTS: Of 307 patients with PanNET who underwent resection, recurrence occurred in 79 (26%) of patients. For stage I and II disease, 5-year RFS rates were 90% and 43%, whereas 5-year DSS rates were 98% and 86% (P < 0.0001 and P = 0.0038, respectively). For grades 1, 2, and 3 disease, 5-year RFS rates were 87%, 49%, and 18%, and 5-year DSS rates were 98%, 89%, and 51% (P < 0.0001 for both). Stage II, grade 2, and grade 3 disease were each associated with increased recurrence and disease-specific death. CONCLUSIONS: Stage and grade are important prognostic factors that should be utilized to tailor postsurgical surveillance after curative resection of PanNET.

Postponing trauma: the dangers of telling.

Surviving a major historical trauma has consequences that are difficult to live with. Survivors who remain silent are often condemned to a desiccated existence, a dried-out life, a death in life. Survivors who speak out run an even greater risk. Telling their ghastly tale may trigger somatic consequences, psychotic episodes, or even suicide. As to the psychoanalytic cure, the free association it requires carries its own danger: negative therapeutic reaction in sometimes extreme forms. Avoidance of horror may turn into avoidance of life itself. Awful as it may seem, this avoidance of life may represent a victory over a menacing chaos. Should we as analysts accept the risk of endangering such a victory, no matter how unsatisfactory? The psychoanalytical injunction to speak out may trigger an upsurge of shame and terror. Is subjectivation always possible? This paper is about what happens when denial and splitting strategies are suspended, when 'crypts' are opened. Is there an analytic 'poros' allowing for a controlled return of affects? Is there a therapeutic solution to the problem of telling a wreckage without being caught in it? The dangers of 'telling' will be discussed in regard to new analytic strategies and new interpretive registers. When the 'silent psychic sharing' proves insufficient, some analysts go so far as to take part in the shame, share the grief, 'lend their own psyche', become a 'double' of the analysand, accept the existence of 'sanctuaries'. To what effect?

A RETROPERITONEAL SEMINOMA WITH ENTRAPPED NERVE GANGLION MASQUERADING AS A PARAGANGLIOMA.

OBJECTIVE: The differential diagnosis of retroperito-neal tumors includes lymphoid, germ cell, and neurogenic tumors such as paraganglioma. Paragangliomas are rare neuroendocrine tumors of the autonomic nervous system, which may secrete catecholamines and their metabolites. Clinical features include sustained or paroxysmal hypertension, headaches, sweating, and palpitations. Here we present an unusual case of a retroperitoneal tumor entrapping a sympathetic nerve ganglion and mimicking paraganglioma. METHODS: A 57-year-old man with a history of controlled hypertension presented with paroxysms of tachycardia, flushing, high blood pressure, and headache. Ambulatory blood pressure monitoring showed uncontrolled labile hypertension with a normal nocturnal dip. Abdominal computed tomography (CT) demonstrated a 6.1 cm mass in the right retroperitoneum with adjacent lymphadenopathy. Paraganglioma was suspected and 24-hour urine demonstrated elevated normetanephrines (575 mcg/24 hours; normal, 5 to 290 mcg/24 hours) and vanillylmandelic acid (8.3 mg/24 hours; normal, 0.5 to 6.6 mg/24 hours). 68-Gallium DOTATATE positron emission tomography/CT showed weak uptake in the retroperitoneal mass and no other mass lesions. RESULTS: Following preparation with alpha-adrenergic blockers, surgical excision was performed with diagnostic and curative intent. Postoperatively, hypertension and paroxysmal symptoms resolved completely. The histopathology report described seminoma with an entrapped large ganglion within the tumor. CONCLUSION: We describe a retroperitoneal seminoma with an entrapped ganglion causing hypertension and paroxysmal symptoms, with laboratory and imaging features compatible with paraganglioma. Awareness of the rare possibility of mechanical pressure on a ganglion, within the differential diagnosis of retroperitoneal mass and sympathetic symptoms may aid in clinical decision making in atypical cases.

Indeterminate nodules by the Bethesda system for reporting thyroid cytopathology in Israel: Frequency, and risk of malignancy after reclassification of follicular thyroid neoplasm with papillary-like features.

OBJECTIVE: We aimed to determine the frequency and risk of malignancy (ROM) for indeterminate thyroid nodules, categories III (B3) and IV (B4) of the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), at a large institution in Israel. Additionally, we investigated the impact of redefining follicular neoplasm with papillary-like nuclear features (NIFTP) as non-malignant on malignancy rates. METHODS: In this retrospective study of all thyroid fine needle aspirations (FNAs) performed at Tel Aviv-Sourasky Medical Center between January 2013 and December 2015, we assessed ROM for B3 and B4 nodules. Potential risk factors thought to affect a-priori ROM were assessed. Suspected NIFTP lesions were re-examined, and if proven, reclassified as benign. RESULTS: 3701 nodules were sampled in 2919 FNAs performed on 2674 patients. B3 reports comprised 7.7% of all nodules (n = 284); B4 represented 3.6% (n = 132). In multivariate logistic regression, male gender, being of former Soviet Union origin, and smoking increased ROM for B3 nodules by a factor of 7.97 (P = 0.002; CI: 2.2-23.4), 9.15 (P = 0.021; CI:1.4-60.0), and 11.0 (P = 0.001; CI 2.8-44.8), respectively. Reclassifying NIFTP decreased ROM from 14% to 12.5% for B3, and from 26.7% to 25% for B4 nodules. NIFTP comprised 9.5% of previously diagnosed resected malignant tumors. CONCLUSIONS: The relative frequencies of B3 and B4 nodules and their associated malignancy rates were consistent with previous series. Risk factors identified for malignancy may help characterize patients most likely to benefit from surgery. Reclassifying NIFTP had a substantial impact on the ROM in the resected tumors previously diagnosed as malignant.

Comparison of Quality Oncology Practice Initiative Metrics in Solid Tumor Oncology Clinic With or Without Concomitant Supportive Oncology Consultation.

PURPOSE: The Quality Oncology Practice Initiative (QOPI) is a quality measurement and improvement program designed to assess practice performance for various consensus-based and evidence-based measures. In this study, we evaluated differences in QOPI metrics met among patients with advanced solid cancer receiving routine oncologic care alone (routine care) compared with patients receiving integrated oncology and specialty-level palliative care (supportive care). METHODS: We conducted a retrospective chart review of 100 randomly selected patients treated between June 2013 and June 2015 from our supportive care group and matched these patients to 100 routine care group patients on the basis of tumor type and initial oncology visit date. We used the electronic medical record to collect data regarding patient demographics, palliative care-specific QOPI metrics, intensive care unit admissions, and hospice enrollment. We performed multivariate analysis comparing differences between the two groups. RESULTS: A total of 200 patients were included. Both groups had similar baseline characteristics. Supportive care consultation improved the absolute number of QOPI metrics met ( P = .01). The QOPI metrics more likely to be met included the following: pain appropriately addressed ( P < .01), advance care directives documented by third office visit ( P < .01), and longer hospice enrollment ( P < .01). CONCLUSION: Integrating palliative care consultation with routine oncologic care improved pain management and end-of-life planning and care. Properly addressing pain and guiding advance care discussions require specialized skills. These data support the need for increased primary palliative care education for oncologists and further development of supportive oncology practices.

Clinical performance evaluation of a novel, automated chemiluminescent immunoassay, QUANTA Flash CTD Screen Plus.

The QUANTA Flash(®) CTD Screen Plus is a chemiluminescent immunoassay (CIA) for the detection of the major antinuclear antibodies (ANA) on the BIO-FLASH(®) platform. NOVA View(®) is an automated fluorescence microscope that acquires digital images of indirect immunofluorescent assay (IFA) slides. Our goal was to evaluate the clinical performance of the two automated systems and compare their performance to that of traditional IFA. Sera from patients with systemic autoimmune rheumatic diseases (SARD, n = 178), along with disease and healthy controls (n = 204), were tested with the CTD CIA and with NOVA Lite(®) HEp-2 ANA, using both the manual method of reading the IFA slides and the NOVA View instrument. The CTD CIA showed 78.1% sensitivity for SARD, coupled with 94.1% specificity. Manual IFA and NOVA View showed somewhat higher sensitivity (81.5 and 84.8% in SARD, respectively), but significantly lower specificity (79.4 and 64.7%, respectively). Both automated systems displayed somewhat different performance, due to the different principals of ANA detection: IFA with NOVA View digital image interpretation had higher sensitivity, while the CTD CIA showed higher specificity. With the added benefits of full automation, the new CTD CIA is an attractive alternative to traditional ANA screening.

Enzyme-responsive PARACEST MRI contrast agents: a new biomedical imaging approach for studies of the proteasome.

Proteases are important biomarkers for many biological processes and are popular targets for therapeutics investigations. A protease can be detected by monitoring changes in the paramagnetic chemical exchange saturation transfer (PARACEST) effect of a MRI contrast agent that serves as a substrate for the protease. To translate this type of responsive PARACEST MRI contrast agent to in vivo applications, the sensitivity, timing, specificity and validation of the response of the agent must be evaluated. This report demonstrates that PARACEST MRI contrast agents can be used to detect nanomolar concentrations of proteases, can be designed to preferentially detect the protease caspase-3 relative to caspase-8, and can be detected within the 15 min time frame of typical MRI studies. The response can be validated using an unresponsive PARACEST MRI contrast agent as a control. A survey of the MEROPS database shows that this approach may also be applied to detect other proteases, and therefore may represent a new platform technology for studies of the proteasome.

¿Se puede morir de decir?: Sarah Kofman, Primo Levi / Dying from having sopoken?: Sarah Kofman, Primo Levi

¿Se puede morir por escribir la catástrofe? ¿Es necesario ver en la divulgación, las fantasías inconscientes que están subyacentes, el retorno de los afectos que conlleva, una decisión de graves consecuencias? Tales son los interrogantes planteados en el curso de una exploración de trayectorias literarias que llevan a dos escritores a testimoniar cada vez más directamente sobre una experiencia, incluso en sus aspectos más inconfesables. Los dos escritores, Sarah Kofman, y Primo Levi no sobreviven
