Background (Es)ketamine and monoamine oxidase inhibitors (MAOIs), e.g., tranylcypromine, are therapeutic options for treatment-resistant major depression. Simultaneous administration is currently not recommended because of concern about hypertensive crises. Objective Our objective was to evaluate whether changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) during esketamine administration differed between patients who concomitantly received tranylcypromine and those who did not. Methods This was a retrospective cohort study utilizing cardiovascular monitoring data from inpatients treated for severe depression in unipolar, bipolar, and schizoaffective disorder. Primary outcomes were change in mean BP and HR during the first hour after intravenous or subcutaneous esketamine administration compared with baseline, controlled for confounders. Secondary analyses quantify differences in absolute BP during esketamine treatment and comparisons of BP peaks, temporal effects, and intraindividual comparisons before and after tranylcypromine initiation. Results Our analysis included 509 esketamine administrations in 43 patients, 14 of whom concomitantly received tranylcypromine. Controlling for creatinine and age, mean ± standard deviation (SD) BP changes were significantly increased by concomitant tranylcypromine treatment (ΔSBP: F[1,503] = 86.73, p

In Deutschland werden rund 3 % aller Neugeborenen nach einer Kinderwunschbehandlung geboren. Haufigste Methode der assistierten Reproduktion (assisted reproductive technique [ART]) ist die intrazytoplasmatische Spermieninjektion (intracytoplasmic sperm injection [ICSI]). Ob es gesundheitliche Benachteiligungen bei Kindern und Jugendlichen, die nach einer ICSI-Behandlung geboren wurden, gibt, wird kontrovers diskutiert. In der Deutschen ICSI-Langzeitstudie wurde eine Kohorte von Kindern, die nach einer ICSI-Behandlung in den Jahren 1998 bis 2000 geboren wurden, zu drei Untersuchungszeitpunkten hinsichtlich ihrer gesundheitlichen, psychischen und sozialen Entwicklung untersucht (ICSI-Studie I–III). Der Schwerpunkt der ersten Untersuchung war der Schwangerschafts- und Geburtsverlauf sowie die neonatale Gesundheit der Kinder. Im zweiten Untersuchungszeitraum (2004–2006) wurde die somatische und neurologische Entwicklung der Einlinge untersucht, wahrend 2015–2017 (dritter Untersuchungszeitraum) die kardiometabolische und endokrinologische Entwicklung der Jugendlichen sowie deren Lebensqualitat und soziale Entwicklung im Mittelpunkt standen. Insgesamt kann festgestellt werden, dass die physische und psychische Entwicklung der Kinder vergleichbar zu spontan konzipierten Gleichaltrigen verlauft. Die Fehlbildungsrate nach ICSI ist geringfugig erhoht und das Geburtsgewicht etwas niedriger als bei spontan konzipierten Kindern. Die Mehrlingsrate ist erhoht, was u. a. zu mehr Fruhgeburtlichkeit mit entsprechenden Folgen fuhrt. Unterschiede in den metabolischen Faktoren konnen auf ein erhohtes Risiko fur kardiovaskulare Erkrankungen im spateren Lebensverlauf hinweisen. Ob das Verfahren der ICSI zu klinisch relevanten kardiovaskularen Risiken fuhrt, muss in weiteren Studien untersucht werden.

Dupilumab has recently been approved by the Food and Drug Administration for use for treatment of moderate to severe atopic dermatitis in children aged 6 to 11 years. It presents a novel treatment option with a favorable safety profile for patients who are currently reliant on immunosuppressants, including cyclosporine A, methotrexate, and mycophenolate mofetil. Particularly during the current COVID-19 pandemic, immunosuppression should be avoided to retain intrinsic antiviral immunity. Transitioning to dupilumab should be executed strategically-tapering immunosuppressants and minimizing risk of flare by overlapping with the biologic. Herein, we use results of outcome measurements from LIBERTY AD ADOL and LIBERTY AD PEDS trials of dupilumab in adolescents aged 12 to 18 years and children aged 6 to 11 years, respectively, to propose a schematic for an 8-week transition between medications.

Background Physician burnout is a common problem that can have negative ramifications for both physicians and patients. Lack of effective coping mechanisms decreases resilience, which can lead to burnout, and women may be particularly vulnerable. Objective We aimed to evaluate resilience by generation among professionals in dermatology. We hope to gain a better understanding of the plasticity of resilience traits to identify modifiable resilience components. Methods Attendees of the 2020 Women’s Dermatological Society Forum were asked to complete an 80-item questionnaire evaluating eight characteristics of resilience. Each participant received scores electronically, and attendees were invited to anonymously submit scores, job category (physician or industry), and birth year and/or generation category. Participants who provided scores and were part of the millennial generation (born 1980–1994; ages 26–40 years at the time of survey completion), Generation X (born 1965–1979; ages 41–55 years), or baby boomer generation (born 1944–1964; ages 56–76 years) were included. Results Of the 67 participants meeting the inclusion criteria, 96.7% were women and 3.3% were men, 69.4% were physicians and 30.6% were industry representatives. Millennials accounted for 43.3%, Generation X for 35.8%, and baby boomers for 20.9% of the study participants. There was a significant difference among the three generations for mean scores on rumination (p = .0071) and flexibility (p = .0005), with scores becoming more ideal for older generations. There was no significant difference among generations for other resilience or burnout indicators, including emotional inhibition, toxic achieving, avoidance coping, perfect control, detached coping, and sensitivity. Conclusion Resilience traits such as rumination and flexibility differed by generation, with the most favorable scores occurring in the oldest cohort, suggesting that some resilience traits may be malleable and improve with age or be inherently affected by environment during development. Health care professionals may benefit from engaging in activities that enhance malleable resilience traits and improve the ability to manage work-related stressors.

Clinical trials are currently underway to evaluate the benefit of dupilumab in treating allergic contact dermatitis (ACD). Dupilumab use has been reported to improve ACD reactions in some patients, but not all. Varying clinical responses to T helper 2 (TH2) inhibition challenge the classical view that ACD proceeds through a TH1-dominant pathway. Selective TH2 inhibitors, such as dupilumab, may attenuate ACD when the delayed hypersensitivity response is due to TH2-predominate activation; conversely, it may have no effect on ACD if it is elicited via TH1 or TH17 pathways. We hypothesize that allergen-specific T-cell responses and patient-specific factors both play an important role in determining which pathways are recalled in delayed hypersensitivity reactions.

OBJECTIVE During cochlear implantation, electrophysiological tests are performed to document safe technical functioning of implant and electrodes. In rare cases, the apical part of the electrode folds over during insertion. The data from transimpedance matrix (TIM) measurements enable the generation of a heat map or TIM profile measuring the spatial distribution of voltage. The aim of this study was to determine the accuracy of heat-map TIM profiles and compare them with spread of excitation (SOE) measurements and intraoperative imaging for prediction of electrode malposition. STUDY DESIGN Non-randomized study. SETTING Tertiary referral center. PATIENTS AND INTERVENTIONS One hundred patients who underwent cochlear implantation with completed TIM measurements, SOE data and perioperative imaging met the inclusion criteria and were enrolled. MAIN OUTCOME MEASURE The electrophysiological data on the electrode array positioning was compared with temporal bone imaging. RESULTS In seven cases, TIM measurements showed irregular results. In two cases, irregular TIM profiles were registered, but SOE data and 3D x-ray of the temporal bone didn't display deviated electrode positioning. A 3D x-ray of the skull displayed electrode tip fold-over in four cases and electrode buckling in one case. Sensitivity of TIM measurements and SOE data was 100%, specificity of TIM measurements was 97.89%, and specificity of SOE data was 98.93%. CONCLUSION Out of 100 patients using TIM measurements for detection of electrode malpositioning, no false negative cases were detected. TIM measurements successfully detect electrode malposition in an intraoperative setting. Different heat map patterns may be observed depending on location and type of malposition.

Background To investigate the impact of insurance status on outcomes in patients with hepatocellular carcinoma (HCC). Methods Patients diagnosed with HCC in the cancer registry from 2005 to 2016 were retrospectively stratified by insurance group. Overall survival was assessed via Kaplan‐Meier curves and Cox proportional hazard models including potential confounders in multivariable analyses. Results Seven hundred and sixty‐nine patients met inclusion criteria (median age 63 years, 78.8% male, 65.9% Caucasian). 44.5% had private insurance (n = 342), 29.1% had Medicare (n = 224), and 26.4% had Medicaid (n = 203). At diagnosis, Medicaid patients had higher rates of Child‐Pugh B (32.0%) and C disease (23.6%) vs Medicare (28.6% and 9.8%) and private insurance (26.9% and 6.7%, P, Medicaid is associated with advanced liver cirrhosis at time of hepatocellular carcinoma diagnosis. Primary insurance is not an independent predictor of survival.

The aim of the current study was to compare the diagnostic precision and reliability of different methods in measuring Hill–Sachs lesions (HSLs) using MRI and CT. A total of 80 consecutive patients with a history of anterior shoulder instability were retrospectively included. The preoperative CT and MRI scans of the affected shoulders were analysed. To investigate the ability of the Franceschi grading, Calandra classification, Richards, Hall, and Rowe grading scale, Flatow percentage and “glenoid track” assessment according to Di Giacomo et al. to quantify the extent of humeral bone loss, the results of each measurement method obtained with MRI were compared with those achieved with CT. In addition, the intra- and inter-rater reliabilities of each measurement method using CT and MRI were calculated and compared. A significant difference was found between CT and MRI in the determination of the Hill–Sachs interval (HSI) (p = 0.016), but not between the results of any of the other measurement techniques. With the exceptions of the Franceschi grade and Calandra classification, all measurement methods showed good or excellent intra- and inter-rater reliabilities for both MRI and CT. While the determination of the HSI with MRI was more accurate, all other analysed techniques for measuring the amount of humeral bone loss showed similar diagnostic precision. With regard to the intra- and inter-rater reliabilities, all measurement techniques analysed, with the exception of the Franceschi and Calandra classifications, provided good to very good reliabilities with both CT and MRI.

Checkpoint inhibitors have demonstrated clinical impact in colorectal cancer with deficient mismatch repair and high microsatellite instability. However, the majority of patients have disease with stable microsatellites that responds poorly to immunotherapies. Combinations of checkpoint inhibitors are under investigation as a way of increasing immunogenicity and promoting a robust anti-tumor immune response. The purpose of this study is to quantify the immune responses induced by mono and dual checkpoint inhibition in a mismatch repair proficient model of colorectal cancer (CRC). Tumor growth rates were monitored over time and compared between groups. We utilized fluorescence-activated cell sorting to analyze CD8+ and CD4+ T cells after treatment with either single PD-1 inhibition or dual PD-1 and CTLA-4 inhibition. Additionally, we sought to quantify the expression of co-inhibitory surface molecules PD-1, LAG3, and TIM3. Dual checkpoint inhibition was associated with a significantly slower growth rate as compared to either mono PD-1 inhibition or control (p + T cells demonstrated significantly less expression of PD-1 (1700 vs. 2545 and 2462; p p p

Purpose Numerous endeavors have been undertaken to preserve hearing in cochlear implant (CI) patients. Particularly, optimization of electrode array design aims at preservation of residual hearing (RH). This study examines whether a slim perimodiolar (PM) electrode array could bear the capability to preserve hearing. Methods A total of 47 patients underwent cochlear implantation receiving the PM electrode. (i) Patients with pure tone audiogram (PTA) thresholds better than 85 dB and/or hearing loss for Freiburg speech test numbers less than 60 dB and more than 50% maximum monosyllabic understanding were assigned to the RH group (n = 17), while all others belonged to the noRH group (n = 30). (ii) Another group implanted with a slim straight, lateral wall (LW) electrode was recruited for comparison. Results We compared 17 RH–30 noRH patients all receiving the PM electrode. RH in PM recipients decreased faster than in LW recipients. No significant differences were observed between both (RH v/s noRH) groups in NRT thresholds, Freiburg speech test and A§E® phonemes. Analogous satisfaction levels were indicated through the questionnaires in terms of sound quality, hearing in silence, noise and directional hearing in both groups. Conclusions The results suggest that hearing preservation is influenced not only by electrode shape but various factors. This study opens an avenue for further investigations to elucidate and enumerate the causes for progressive hearing loss.

Imaging of CD8 receptors on T-cells by positron emission tomography (PET) has been considered a promising strategy for monitoring the treatment response to immunotherapy. In this study, a trial of imaging CD8 with our newly developed sequential multiple-agent receptor targeting (SMART) technology was conducted. Mice bearing a subcutaneous colorectal CT26 tumor received three times different immunotherapy treatments (PD1 or CTLA4 or combined). On either day 7 or day 14 after the first time treatment, the PET imaging study was performed with sequentially administered TCO-modified anti-CD8 antibody and 64Cu-labeled MeTz-NOTA-RGD. However, no positive response was detected, probably due to (1) inappropriate selection of biomarkers for the SMART strategy, (2) limited TCO modification on the anti-CD8 antibody, and (3) inadequate response of the CT26 tumor to the selected immunotherapies. Therefore, the potential of applying SMART in imaging CD8 was not demonstrated in this study, and further optimization will be necessary before it can be applied in imaging CD8.

Purpose Accurate therapeutic management of the neck is a challenge in patients with supraglottic laryngeal cancer. Nodal metastasis is common at all disease stages, and treatment planning relies on clinical staging of the neck, for both surgical and non-surgical treatment. Here, we compared clinical and surgical staging results in supraglottic carcinoma patients treated with primary surgery to assess the accuracy of pre-therapeutic clinical staging and guide future treatment decisions. Methods Retrospective analysis of clinical, pathological, and oncologic outcome data of 70 patients treated with primary surgery and bilateral neck dissection for supraglottic laryngeal cancer. Patients where clinical and pathological neck staging results differed, were identified and analyzed in detail. Results On pathologic assessment, patients with early stage (pT1/2) primaries showed cervical lymph node metastases in 55% (n = 17/31) of cases, compared to 67% (n = 26/39) of patients with pT3/4 tumors. In 24% (n = 17/70) of all patients, cN status differed from pN status, resulting in an upstaging in 16% of cases (n = 11/70) and a downstaging in 9% (n = 6/70) of cases. 14% of patients with cN0 status had occult metastases (n = 5/30). As assessed by a retrospective tumor board, in case of a non-surgical treatment approach, the inaccurate clinical staging of the neck would have led to an over- or undertreatment of the neck in 20% (n = 14/70) of all patients. Conclusion Our data re-emphasize the high cervical metastasis rates of supraglottic laryngeal cancer across all stages. Inaccurate clinical staging of the neck is common and should be taken into consideration when planning treatment.

Background Inflammation and the immune system significantly impact the development, progression, and treatment response of hepatocellular carcinoma (HCC). This retrospective study investigated the neutrophil‐to‐lymphocyte ratio (NLR) as a prognostic biomarker in Western patients with HCC in the setting of chronic viral hepatitis. Methods Patients diagnosed with HCC from 2005 to 2016 were selected from a tertiary care institution. NLR was calculated within 30 days prior to treatment and dichotomized at the median. Kaplan–Meier overall survival (OS) curves and Cox hazard proportional models were utilized. Tumor and liver reserve parameters were included in multivariable analyses (MVA). Results A total of 581 patients met inclusion criteria (median age 61.0 yr; 78.3% male; 66.3% Caucasian) with median OS = 34.9 mo. 371 patients (63.9%) had viral hepatitis, of which 350 had hepatitis C (94.3%). The low‐NLR group (, Lower baseline NLR was associated with increased overall survival in HCC. Chronic viral hepatitis serves as an effect modifier of NLR, attenuating its prognostic relevance in this hepatitis C‐predominant population.

To assess serum lactate dehydrogenase (LDH) as a pretreatment prognostic factor in patients with uveal melanoma liver metastases treated with transarterial hepatic chemoperfusion (THC). 56 patients (48 % male, median age: 63.5 years) underwent a median of 4 THC sessions. Kaplan-Meier for median overall survival (OS) and time to hepatic progression (TTP; 95 %CI) in months and Cox proportional hazards model for uni- (UVA)multivariate analyses (MVA) for hazard ratio (HR) evaluation were calculated. The median OS was 9.4 months. The pretreatment LDH value before 1st THC was the strongest OS predictor with 19.8 months for normal (≦ 280 units per liter (U/L)), 9.7 for intermediate ( 280- 1000 U/L), and 3.84 months for high (≧ 1000 U/L) LDH. LDH significantly predicted a median TTP with 8 months, 4 months, and 1 month for normal, intermediate, and high LDH, respectively. UVA revealed intermediate (16.5) and high (77.3) LDH, bilirubin the upper limit of normal (ULN) (2.89), alkaline phosphatase 1.5 ULN (6.8), leukocytes ULN (4.2), gamma-glutamyl transferase (GGT) ULN (7), extrahepatic metastases (1.8) and liver lesions ≥ 5 cm (3.6) as significant predictors for worse OS. MVA confirmed intermediate (5) and high (27.1) LDH, bilirubin (5.7), GGT (2.9), and tumor size ≥ 5 cm (3.7) as significant independent predictors for worse OS. Patients with decreasing vs. increasing LDH 10 % between 1st and 2nd THC (median: 38 days) survived longer (14.6 vs. 4.3 months) and progressed later (7 months vs. 1 month). Elevated pretreatment serum LDH is an essential and robust OS and TTP predictor, potentially allowing for the identification of patients benefiting most from transarterial hepatic chemoperfusion.· Pretherapeutic LDH is the most reliable prognosticator for OS and TTP. · Therapy-related LDH decrease 10 % between 1st and 2nd THC had prolonged OS and TTP. · Lower Values of LDH, bilirubin, gamma-glutamyl transferase, and tumor size are independent pretherapeutic predictors for longer OS. · Extrahepatic metastases do not have an independent influence on overall survival.· Ludwig J, Haubold J, Heusner T et al. Lactate Dehydrogenase Prior to Transarterial Hepatic Chemoperfusion Predicts Survival and Time to Progression in Patients with Uveal Melanoma Liver Metastases. Fortschr Röntgenstr 2021; 193: 683 - 691.ZIEL: Beurteilung der Serum-Laktatdehydrogenase (LDH) als prätherapeutischer prognostischer Faktor bei Patienten mit Lebermetastasen eines Aderhautmelanoms, die mit der transarteriellen hepatischen Chemoperfusion (THC) behandelt wurden. 56 Patienten (48 % männlich, medianes Alter: 63,5 Jahre) erhielten im Median 4 Behandlungen. Die Kaplan-Meier-Analyse für das mediane Gesamtüberleben und die Zeit bis zur hepatischen Tumorprogression (TTP; 95 %-KI) in Monaten sowie das Cox-Proportional-Hazard-Modell für die univariate (UVA) und multivariate Analyse (MVA) zur Bewertung des Risikoquotienten (HR) wurden berechnet. Das mediane Überleben betrug 9,4 Monate. Der LDH-Wert vor der ersten Behandlung war der stärkste Prädiktor für das Überleben mit 19,8 Monaten für normale (≦ 280 Einheiten/Liter (U/L)), 9,7 Monaten für mittlere ( 280– 1000 U/L) und 3,84 Monaten für hohe (≧ 1000 U/L) LDH-Werte. Die LDH war der signifikanteste Vorhersagewert für die TTP mit 8, 4 und 1 Monaten für normale, mittlere bzw. hohe LDH-Werte. Die UVA identifizierte mittlere (16,5) und hohe (77,3) LDH-Werte, Bilirubin Obergrenze des Normalbereichs (ULN) (2,89), alkalische Phosphatase 1,5 ULN (6,8), Leukozyten ULN (4,2), Gamma-Glutamyltransferase (GGT) ULN (7), extrahepatische Metastasen (1,8) und Leberläsionen ≥ 5 cm (3,6) als signifikante Prädiktoren für ein kürzeres Überleben. Die MVA bestätigte mittlere (5,0) und hohe (27,1) LDH-Werte, Bilirubin (5,7), GGT (2,9) und eine Tumorgröße von ≥ 5 cm (3,7) als unabhängige signifikante Prädiktoren für das Überleben. Patienten mit einer LDH-Abnahme vs. einer Zunahme 10 % zwischen der ersten und zweiten Behandlung (median: 38 Tage) überlebten länger (14,6 vs. 4,3 Monate) und zeigten eine spätere Progression (7 vs. 1 Monate). Ein erhöhter prätherapeutischer LDH-Wert ist ein wesentlicher und robuster OS- und TTP-Prädiktor, der es potenziell ermöglicht die Patienten zu identifizieren, welche am meisten von der transarteriellen hepatischen Chemoperfusion profitieren.· Prätherapeutisches LDH ist der stärkste prognostische Faktor für das Überleben und die Tumorprogression. · Eine therapiebedingte LDH-Abnahme 10 % zwischen der ersten und zweiten Behandlung ist mit einem längeren OS und TTP assoziiert. · Niedrigere LDH, Bilirubin und Gamma-Glutamyl-Transferase Werte sowie kleinere Tumore sind unabhängige prätherapeutische Prädiktoren für ein längeres Gesamtüberleben. · Extrahepatische Metastasen haben keinen unabhängigen Einfluss auf das Gesamtüberleben.

While dietary triggers have been investigated in acne and other inflammatory follicular dermatoses, there is a paucity of data on diet and hidradenitis suppurativa (HS). We sought to identify exacerbating and alleviating foods in HS patients. An anonymous survey was distributed via HS Facebook support groups and in person at HS specialty clinics. Participants were asked to select all that apply from a list to indicate foods that worsen and make HS better including sweet foods, breads and pasta, red meat, chicken, fish, canned foods, fruits, vegetables, dairy, high-fat foods, I do not know, and no. Only 12.0% (n = 89/744) identified alleviating foods while 32.6% (n = 237/728) identified HS-symptom-exacerbating foods. The most commonly reported exacerbating foods were sweets (67.9%), bread/pasta/rice (51.1%), dairy (50.6%), and high-fat foods (44.2%). The most commonly reported alleviating foods included vegetables (78.7%), fruit (56.2%), chicken (51.7%), and fish (42.7%). Further studies are required to evaluate the mechanistic links between diet and HS. HS patients may benefit from receiving dietary counseling as part of a comprehensive HS management plan.

Atopic dermatitis (AD), a chronic inflammatory skin condition, negatively affects sexual health in various ways including causing physical discomfort and changes in physical appearance that can lead to low self-confidence. The chronic and debilitating nature of this disease can interfere with the sexual well-being of patients and their partners. This review describes the ways that AD affects sexual health. In addition, we review the impact that partnered relationships and physical intimacy can have on AD and provide practical recommendations for optimizing sexual health in AD patients.

e16119 Background: Assessment of the clinical outcomes and prognostic value of genomic mutations in colorectal liver metastases treated with Y90 radioembolization. Methods: Multi-institution retrospective study of patients who underwent Y-90 radioembolization treatment after tumor genotyping was completed for CRLM. Patients treated between 2008 and 2019 were included from 7 institutions within the United States and Europe. Patient demographics, tumor characteristics, pre- and post- treatment regimens, serum laboratory evaluation and overall survival were analyzed between patients with differing histopathologic and genomic status. Tumor genotyping was obtained for KRAS, BRAF, PIK3CA, AKT, MEK, NRAS and MMR genes. Kaplan-Meier survival estimation and multivariate Cox regression were analyzed. Results: 434 patients treated with Y90 radioembolization fulfilled the inclusion criteria. Of the total cohort, 399 patients were available who had sufficient documented tumor profiling data. Average age at diagnosis was found to be 58.8 years for all patients (60.1% male, 39.9% female). Decreased survival post Y-90 treatment was shown in those patients with increased number of documented tumor mutations (n = 0,1 or ≥2 mutations: median OS 9.63 mos vs. 6.2 mos vs. 5.3 mos; p < 0.0001). Additionally, the median survival in patients with mutated BRAF was 5.0 months, as compared to 9.4 months in those patients with wild-type BRAF (p = 0.0009). Primary colon cancer sidedness was also shown to demonstrate significant difference in survival post-Y90 treatment with left sided primaries showing improved median overall survival (left = 7.5 mos vs. right = 6.3 mos; p = 0.04.) Patient demographics including gender, age and race were not shown to be significant in overall survival post-Y90 treatment (p-values > 0.05). Number of tumor mutations (p < 0.0001, HR = 1.69 CI: 1.39-2.05), BRAF status (p = 0.02, HR = 2.6 CI:1.20-4.9), primary sidedness (p = 0.01, HR = 0.65 CI:0.47-0.90), pre-treatment neutrophil-lymphocyte ratio (p = 0.04, HR = 1.42 CI: 1.02-1.98) and KRAS mutation status (p < 0.0001, HR = 1.81 CI: 1.45-2.26) all persisted as significant predictors of survival on multivariate analysis. Conclusions: Number of tumor mutations, BRAF mutation status, primary tumor sidedness, neutrophil-lymphocyte ratio and KRAS mutation status are all shown to be significant prognostic factors in patients with colorectal liver metastases receiving Y90 radioembolization.

Interventional oncology (IO) and oncoimmunology (OI) are fields that have significantly evolved during the last two decades and are providing new opportunities to conquer cancer with a safe and effective treatment profile. Novel IO treatments have the potential to complement OI and sensitize “cold” tumors to immunostimulatory therapies with the ultimate aim of improving patient outcomes. In this manuscript, we provide an overview of the current knowledge of the immune system in cancer, the potential for IO to modulate the immune system, and how IO and OI may synergize.

Ingredients found in facial moisturizers can impact a myriad of skin conditions, including sensitive skin syndrome and contact dermatitis. There is a paucity of evidence on the allergenic potential and marketing claims of facial moisturizers, posing challenges to clinician recommendation and consumer selection. In this study, we systematically evaluate the 100 top-selling sun protective facial moisturizers that claim to be natural, fragrance free, expert-approved, age preventing, beneficial for sensitive skin, and sun protective. Allergenic potential of these moisturizers is evaluated based on ingredients used and prices and consumer ratings are compared. Accordingly, 75 of 100 marketed at least one additional benefit. "Anti-aging" products had the highest average price ($14.99/oz) and "expert-approved" had the lowest ($5.91/oz). Consumer rating was highest for facial moisturizers that were "fragrance-free" (4.35/5.00) whereas products that were "natural" received the lowest ratings (3.49/5.00). The most prevalent allergens found in these moisturizers were ethylenediamine tetraacetic acid (EDTA), phenoxyethanol, and cetyl alcohol. "Expert-approved" products had the fewest average allergens in their ingredient lists (P=0.033), whereas products advertising "SPF" had significantly more (P

Purpose To compare adverse events and survival outcomes, including cancer-specific survival and overall survival (OS), in patients with T1aN0M0 renal cell carcinoma (RCC) who are undergoing partial nephrectomy (PN), radical nephrectomy (RN), thermal ablation (TA), or active surveillance (AS). Materials and Methods Through use of the Surveillance, Epidemiology, and End Results-Medicare-linked database from 2002 to 2011 with at least 1 year of consecutive follow-up, a HIPAA-compliant retrospective propensity score-matched study of patients with T1aN0M0 RCC who underwent PN, RN, TA, or AS was performed. Medicare beneficiaries (n = 10 218) with T1aN0M0 RCC as first primary cancer diagnosis were included. Survival and adverse health outcomes were compared across treatment groups. Results Overall, cancer-specific survival significantly differed in the PN versus RN (P.001), AS versus TA (P = .03), and AS versus PN (P = .002) groups. There were no significant differences when TA was compared with PN or RN, with 9-year cancer-specific survival rates of 96.4% versus 96.3% (PN vs TA, P = .07) and 96.1% versus 96.0% (RN vs TA, P = .14), respectively. With the exception of cancer-specific survival in AS versus RN groups (P = .29), cancer-specific survival and OS for all AS comparisons were significantly lower. In addition, compared with the patients undergoing TA, those in the PN and RN groups had increased rates of renal, cardiovascular, and thromboembolic adverse events up to 1 year after the procedure (P.05 for all comparisons). Conclusion For T1aN0M0 RCC, TA confers cancer-specific survival and OS similar to those seen with surgical management, with significantly fewer adverse outcomes at 1 year after the procedure and similar rates of secondary cancer events compared with surgery.

While much research has been invested in understanding preparedness among emergency managers during natural disasters, substantially less attention has been devoted to evaluating the level of understanding and preparedness among nonemergency management employees who must direct others during natural disasters. Among those second-tier leaders are university residential housing staff, who are responsible for the safety of thousands of youth who may be far from the influence of their family. Using varimax-rotated principal components analysis, an instrument was developed for assessing the knowledge and practices of such residential housing staff at Louisiana State University, Baton Rouge, in the wake of Hurricane Isaac (2012). Relationships were derived between hurricane preparedness and general knowledge of hurricane meteorology, experience with past hurricanes, preparation and threat anxiety, duration of experience of the housing staff and in residing in Baton Rouge, whether the respondent’s primar...

Drei bis 5 % aller Kinder werden nach einer Form der assistierten Reproduktion geboren. Die Schwangerschaften verlaufen komplizierter und mit mehr perinatalen Komplikationen als solche, die spontan bei fertilen Paaren eintreten. Ursache dafur scheint auch ein nicht naher fassbares, mit der Subfertilitat assoziiertes Hintergrundrisiko zu sein. Allerdings spielen moglicherweise weitere Faktoren wie die ovarielle Stimulation und die damit einhergehende unphysiologische Entwicklung des Endometriums eine relevante Rolle. Wenn Kinder am Termin gesund geboren werden, sprechen die Daten dafur, dass diese Kinder sich postnatal weitestgehend unauffallig entwickeln. Nach wie vor wird ein diskret erhohtes onkologisches Risiko diskutiert, das sich zwar von dem spontan konzipierter signifikant unterscheidet, sich aber kaum in absoluten Zahlen niederschlagt. Erste Daten zur Pubertatsentwicklung und Surrogatparameter fur nach einer ICSI (intrazytoplasmatische Spermieninjektion) konzipierten Jungen lassen vermuten, dass ggf. mit einer geringeren Fertilitat im spateren Leben zu rechnen ist. Weitere Daten dazu sind notwendig.

The use of immunomodulation to treat malignancies has seen a recent explosion in interest. The therapeutic appeal of these treatments is far reaching, and many new applications continue to evolve. In particular, immune modulating drugs have the potential to enhance the systemic anticancer immune effects induced by locoregional thermal ablation. The immune responses induced by ablation monotherapy are well documented, but independently they tend to be incapable of evoking a robust antitumor response. By adding immunomodulators to traditional ablative techniques, several researchers have sought to amplify the induced immune response and trigger systemic antitumor activity. This paper summarizes the work done in animal models to investigate the immune effects induced by the combination of ablative therapy and immunomodulation. Combination therapy with radiofrequency ablation, cryoablation, and microwave ablation are all reviewed, and special attention has been paid to the addition of checkpoint blockades. CA extern

Purpose To systematically review the safety and efficacy of transarterial drug-eluting beads, irinotecan (DEBIRI) for the treatment of pretreated patients with unresectable colorectal liver metastases (CRLM). Methods A systematic search of the current literature was conducted to extract publications reporting on the use of DEBIRI for CRLM. Data on the safety and efficacy was extracted and tabulated. Weighted average values (WAV) were calculated for each variable to provide a single value representing the pooled safety and efficacy data. Results 13 studies (15 treatment arms) were evaluated, comprising a total of 850 patients. There were 6 prospective phase I/II trials, 5 retrospective trials and 2 randomized control trials. All papers involved patients previously treated with systemic chemotherapy. The weighted average all-grade toxicity rate was 35.2% (range; 6–100%). The high-grade WAV toxicity rate was 10.1% (range; 0–32%). Weighted average response rates were 56.2% and 51.1% according to RECIST (Response Evaluation Criteria in Solid Tumors) and modified RECIST/EASL (European Association for the Study of the Liver) response criteria respectively. The weighted average progression-free survival and overall survival were 8.1 months and 16.8 months, respectively. Conclusion Transarterial DEBIRI is safe and effective in the treatment of unresectable CRLM to the liver. Further studies are warranted to better define its role in the treatment algorithm of this patient subset.

A brief overview of established predictive and prognostic molecular and genetic biomarkers in colorectal cancer therapies will be discussed. A review of the literature on imaging modalities, genetic, metabolic and other molecular markers and the subsequent outcomes in post-Y 90 treatment will be presented. How these biomarkers and future biomarker research can inform locoregional treatment decisions in the clinical setting of metastatic colorectal cancer lesions of the liver will be explored. There are opportunities for personalized cancer treatment in the setting of Y 90 radioembolization. The ability to predict tumor response after Ytrium-90 radioembolization therapy can greatly impact clinical decision making and enhance treatment outcomes, therefore further research into the field is needed.

Aim: To simulate effects of the new Organ Procurement and Transplantation Network/United Network for Organ Sharing policy on the patients’ characteristics and post orthotopic liver transplantation (OLT) outcome. Materials & methods: The United Network for Organ Sharing database was used to identify patients with hepatocellular carcinoma who were listed for OLT 2002–2014. All patients (actual group) versus simulated group with new 6-month delay in assigning Model for End-Stage Liver Disease score exception and Model for End-Stage Liver Disease exception cap of 34 were compared. Results & conclusion: With the new policy, 7,745 (30.4%) of the transplanted patients would have received a delayed transplantation or not be transplanted. The simulated group also showed significantly higher mean overall survival after OLT (p

Background To investigate the neutrophil‐to‐lymphocyte ratio (NLR), platelet‐to‐lymphocyte ratio (PLR), and systemic immune‐inflammation index (SII) as prognostic biomarkers in intrahepatic cholangiocarcinoma (ICC) with a focus on viral hepatitis and liver status. Methods In this retrospective cohort study, patients from the institutional cancer registry with ICC from 2005 to 2016 were stratified by treatment group. Baseline inflammatory markers were dichotomized at the median. Overall survival (OS) was assessed via Kaplan‐Meier curves and Cox proportional hazard models. Multiple patient, liver, and tumor factors were included in the multivariable analysis (MVA). Results About 131 patients (median age 65 years, 52% male, 76% Caucasian) had a median OS of 13.0 months. Resection/interventional oncology with/without systemic therapy had improved survival vs systemic therapy alone in Child‐Pugh A patients (P, The neutrophil‐to‐lymphocyte ratio (NLR) has the strongest impact as a prognostic marker in intrahepatic cholangiocarcinoma (ICC) versus the platelet‐to‐lymphocyte ratio and systemic immune‐inflammation index, and increased NLR is associated with decreased survival in ICC. The NLR has decreased prognostic utility in patients with advanced liver disease.

Novel approaches with checkpoint inhibitors in immunotherapy continue to be essential in the treatment of non-small cell lung cancer (NSCLC). However, the low rate of primary response and the development of acquired resistance during the immunotherapy limit their long-term effectiveness. The underlying cause of acquired resistance is poorly understood; potential management strategies for patients with acquired resistance are even less clear. Here, we report the case of a 75-year-old female smoker with cough, fatigue, and weight loss that was found to have an 8.6 cm right upper lobe lung lesion with local invasion, adenopathy, and a malignant pericardial effusion. This lesion was biopsied and identified to be cT3N3M1b squamous cell cancer of the lung without any recognizable PD-L1 expression on tumor cells. For her metastatic NSCLC, the patient underwent two lines of conventional chemotherapy before initiation of combination immunotherapy with an anti-PD-L1 and anti-CTLA-4 antibody. Though she initially achieved a response, she thereafter progressed and developed immunotherapy resistant lymph nodal metastasis. While cervical lymph nodes could be surgically removed, another metastasis in an aortocaval area required a more sensitive therapy like thermal ablation. The aortocaval node was partially treated with a single treatment of cryotherapy and demonstrated durable complete response. Cryotherapy for checkpoint immunotherapy resistant metastasis appears to be a safe and feasible treatment for treating metastatic disease in non-small cell lung cancer. The prospect of cryotherapy adjuvancy may enable local control of metastatic disease after initial response to immune checkpoint immunotherapy and may impact on overall outcomes. CA extern

To investigate comparative effectiveness of drug-eluting bead transarterial chemoembolization (DEB-TACE) versus Yttrium-90 (90Y)-radioembolization for hepatocellular carcinoma (HCC). Studies comparing conventional (c)TACE versus 90Y-radioembolization or DEB-TACE for HCC treatment were identified using PubMed/Medline, Embase, and Cochrane databases. The adjusted indirect meta-analytic method for effectiveness comparison of DEB-TACE versus 90Y-radioembolization was used. Wilcoxon rank-sum test was used to compare baseline characteristics. A priori defined sensitivity analysis of stratified study subgroups was performed for primary outcome analyses. Publication bias was tested by Egger’s and Begg’s tests. Fourteen studies comparing DEB-TACE or 90Y-radioembolization with cTACE were included. Analysis revealed a 1-year overall survival benefit for DEB-TACE over 90Y-radioembolization (79 % vs. 54.8 %; OR: 0.57; 95 %CI: 0.355-0.915; p = 0.02; I-squared: 0 %; p > 0.5), but not for the 2-year (61 % vs. 34 %; OR: 0.65; 95%CI: 0.294-1.437; p = 0.29) and 3-year survival (56.4 % vs. 20.9 %; OR: 0.713; 95 % CI: 0.21-2.548; p = 0.62). There was significant heterogeneity in the 2- and 3-year survival analyses. The pooled median overall survival was longer for DEB-TACE (22.6 vs. 14.7 months). There was no significant difference in tumour response rate. DEB-TACE and 90Y-radioembolization are efficacious treatments for patients suffering from HCC; DEB-TACE demonstrated survival benefit at 1-year compared to 90Y-radioembolization but direct comparison is warranted for further evaluation. • This meta-analysis shows greater 1-year survival benefit for DEB-TACE over 90 Y-radioembolization. • DEB-TACE has a favourable 2- & 3-year survival benefit trend over 90 Y-radioembolization. • No significant difference for tumour response was detected. • Direct comparison of these methods for a more robust evaluation is warranted.

To investigate survival outcomes following radioembolization with Yttrium-90 (Y90) for neuroendocrine tumor liver metastases (NETLMs). This study was designed to assess the efficacy of Y90 radioembolization and to evaluate lung shunt fraction (LSF) as a predictor for survival.A single-center, prospective study of 44 consecutive patients (median age: 58.5 years, 29.5 % male) diagnosed with pancreatic (52.3 %) or carcinoid (47.7 %) NETLMs from 2006 to 2012 who underwent Y90 radioembolization was performed. Patients' baseline characteristics, including LSF and median overall survival (OS) from first Y90 radioembolization, were recorded and compared between patients with high (≥10 %) and low (10 %) LSF. Baseline comparisons were performed using Fisher's exact tests for categorical and Mann-Whitney U test for continuous variables. Survival was calculated using the Kaplan-Meier method. Univariate (Wilcoxon rank-sum test) and multivariate analyses (Cox Proportional Hazard Model) for risk factor analysis were performed.There was no statistically significant difference in age, gender, race, tumor properties, or previous treatments between patients with high (n = 15) and low (n = 29) LSF. The median OS was 27.4 months (95 %CI 12.73-55.23), with 4.77 months (95 %CI 2.87-26.73) for high and 42.77 months (95 %CI 18.47-59.73) for low LSF (p = 0.003). Multivariate analysis identified high LSF (p = 0.001), total serum bilirubin1.2 mg (p = 0.016), and lack of pretreatment with octreotide (p = 0.01) as independent prognostic factors for poorer survival. Tumor type and total radiation dose did not predict survival.LSF ≥10 %, elevated bilirubin levels, and lack of pretreatment with octreotide were found to be independent prognostic factors for poorer survival in patients with NETLMs.

Purpose To investigate baseline and early apparent diffusion coefficients (ADC) derived from diffusion-weighted imaging (DWI) as a predictor of objective response (OR) and survival in unresectable hepatocellular carcinoma (HCC) treated with doxorubicin drug-eluting bead (DEB) transcatheter arterial chemoembolization. Materials and Methods In a prospective study, 57 patients underwent DEB chemoembolization. Dynamic contrast-enhanced magnetic resonance imaging and DWI were performed at baseline and 1 and 3 months after DEB chemoembolization. OR was evaluated per modified Response Evaluation Criteria In Solid Tumors (mRECIST) and European Association for the Study of the Liver (EASL) guidelines. Baseline ADCs of tumors that showed OR at 1 and 3 months were compared with nonresponding tumor ADCs by two-sample t test and receiver operating characteristic curves. Additionally, ADC changes at 30 days were correlated with OR. Finally, Kaplan–Meier analysis was used to compare survival between patients with lesions demonstrating more restricted baseline diffusion and others. Results At 1 month, 33 patients (60%) showed OR (21 complete responses and 12 partial responses). At baseline, tumors with OR at 1 month showed significantly more restricted diffusion (0.731 × 10 −3 mm 2 /s) compared with others (1.057 × 10 −3 mm 2 /s; P = .031). No difference between response rates at 1 and 3 months according to mRECIST and EASL was observed. For an area under the curve of 0.965, the sensitivity and specificity of predicting objective tumor response at 1 month using a baseline HCC ADC of 0.83 × 10 −3 mm 2 /s were 91% and 96%, respectively. In addition, patients with lesions with a baseline ADC −3 mm 2 /s showed prolonged survival compared with others ( P Conclusions In unresectable HCC, a baseline ADC −3 mm 2 /s is a predictor of survival and treatment response at 1 and 3 months after DEB chemoembolization with high sensitivity and specificity.

Reliable response criteria are critical for the evaluation of therapeutic response in hepatocellular carcinoma (HCC). Current response assessment is mainly based on: (1) changes in size, which is at times unreliable and lag behind the result of therapy; and (2) contrast enhancement, which can be difficult to quantify in the presence of benign post-procedural changes and in tumors presenting with a heterogeneous pattern of enhancement. Given these challenges, functional magnetic resonance imaging (MRI) techniques, such as diffusion-weighted imaging (DWI) have been recently investigated, aiding specificity to locoregional therapy response assessment and outcome prediction. Briefly, DWI quantifies diffusion of water occurring naturally at a cellular level (Brownian movement), which is restricted in multiple neoplasms because of high cellularity. Disruption of cellular integrity secondary to therapy results in increased water diffusion across the injured membranes. This review will provide an overview of the current literature on DWI therapy response assessment and outcome prediction in HCC following treatment with locoregional therapies.
