POS0195 PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS HAVE AN INCREASED RISK OF MORTALITY, MECHANICAL VENTILATION, AND HOSPITALIZATION FROM COVID-19

Background

Patients with systemic lupus erythematosus (SLE) may have an increased risk of mortality from COVID-19 due to underlying immunosuppression, comorbidities, and abnormalities in the innate immune system. Studies have shown that autoimmune diseases and some immunosuppressive agents are risk factors for hospitalization, ventilation, and mortality from COVID-19.

Objectives

To compare the outcomes of patients with or without SLE who were diagnosed with COVID-19 and to identify the factors associated with 30-day hospitalization, mechanical ventilation, and mortality. We hypothesized that patients with SLE had a higher risk of adverse outcomes.

Methods

This retrospective cohort study used the deidentified Optum COVID-19 electronic health record dataset to identify adult patients with COVID-19 diagnosis from 1/1/2020 – 12/31/2020. The SLE cohort was defined as patients who had two or more international classification of diseases (ICD) 9 or 10 diagnosis codes of 710.0 or M32.xx but not M32.0 within one year before COVID-19 diagnosis and were on either antimalarial or immunosuppressive therapy. The general cohort excluded patients with SLE. We matched SLE cases with controls at a ratio of 1:10 by age, sex, race and ethnicity, and month of COVID-19 diagnosis via a propensity score matching with exact matching for the latter three variables. Outcomes included 30-day mortality, hospitalization, and mechanical ventilation after COVID-19 diagnosis. We performed multivariable logistic regression models to estimate the odds of 30-day mortality, hospitalization, and mechanical ventilation after adjusting for age, sex, race and ethnicity, COVID-19 diagnosis quarter, insurance, region, severe obesity, smoking status, and comorbidities.

Results

We included 687 SLE cases matched with 6,870 controls. After matching, the 30-day mortality for SLE and control was 3.6% and 1.8% (p <0.001), the 30-day mechanical ventilation was 6.0% and 2.5% (p <0.001), and 30-day hospitalization was 31.0% and 17.7% (p <0.001). After multivariable adjustment (Table 1) for age, sex, race, COVID-19 diagnosis quarter, insurance, region, severe obesity, and smoking status, patients with SLE had higher odds of death (Odds Ratio (OR)=2.09; 95% CI 1.31-3.32), mechanical ventilation (OR=2.43; 95% CI 1.67-3.54) and hospitalization (OR=2.06; 95% CI 1.71-2.49). After additionally adjusting for comorbidities, the OR decreased to 1.39 (95%CI 0.79-2.44), 1.81 (95%CI 1.16-2.82), and 1.32 (95%CI 1.05-1.65) for mortality, mechanical ventilation, and hospitalization respectively. Older age, male sex, Hispanic ethnicity or Black race, severe obesity, and smoking had increased risk of adverse outcomes.

Conclusion

Patients with SLE have an increased risks of mortality, mechanical ventilation, and hospitalization within 30 days of COVID-19 diagnosis. The risks decreased after adjustment for comorbidities but remained statistically significant for mechanical ventilation and hospitalization.

Neurological complications in pediatric patients with SARS-CoV-2 infection: a systematic review of the literature

OBJECTIVES

To describe clinical characteristics, laboratory tests, radiological data and outcome of pediatric cases with SARS-CoV-2 infection complicated by neurological involvement.

STUDY DESIGN

A computerized search was conducted using PubMed. An article was considered eligible if it reported data on pediatric patient(s) with neurological involvement related to SARS-CoV-2 infection. We also described a case of an acute disseminated encephalomyelitis (ADEM) in a 5-year-old girl with SARS-CoV-2 infection: this case was also included in the systematic review.

RESULTS

Forty-four articles reporting 59 cases of neurological manifestations in pediatric patients were included in our review. Most (32/59) cases occurred in the course of a multisystem inflammatory syndrome in children (MIS-C). Neurological disorders secondary to cerebrovascular involvement were reported in 10 cases: 4 children with an ischemic stroke, 3 with intracerebral hemorrhage, 1 with a cerebral sinus venous thrombosis, 1 with a subarachnoid hemorrhage, 1 with multiple diffuse microhemorrhages. Reversible splenial lesions were recognized in 9 cases, benign intracranial hypertension in 4 patients, meningoencephalitis in 4 cases, autoimmune encephalitis in 1 girl, cranial nerves impairment in 2 patients and transverse myelitis in 1 case. Five cases had Guillain-Barré syndrome (GBS) and two, including ours, had ADEM. Radiological investigations were performed in almost all cases (45/60): the most recurrent radiological finding was a signal change in the splenium of the corpus callosum. The presence of SARS-CoV-2 viral nucleic acid in the cerebrospinal fluid was proved only in 2 cases. The outcome was favorable in almost all, except in 5 cases.

CONCLUSIONS

Our research highlights the large range of neurological manifestations and their presumed pathogenic pathways associated with SARS-CoV-2 infection in children. Nervous system involvement could be isolated, developing during COVID-19 or after its recovery, or arise in the context of a MIS-C. The most reported neurological manifestations are cerebrovascular accidents, reversible splenial lesions, GBS, benign intracranial hypertension, meningoencephalitis; ADEM is also a possible complication, as we observed in our patient. Further studies are required to investigate all the neurological complications of SARS-CoV-2 infection and their underlying pathogenic mechanism.

NEVBD Pesticide Resistance Monitoring Network: Establishing a Centralized Network to Increase Regional Capacity for Pesticide Resistance Detection and Monitoring

Pesticide resistance in arthropod vectors of disease agents is a growing issue globally. Despite the importance of resistance monitoring to inform mosquito control programs, no regional monitoring programs exist in the United States. The Northeastern Regional Center for Excellence in Vector-Borne Diseases (NEVBD) is a consortium of researchers and public health practitioners with a primary goal of supporting regional vector control activities. NEVBD initiated a pesticide resistance monitoring program to detect resistant mosquito populations throughout the northeastern United States. A regionwide survey was distributed to vector control agencies to determine needs and refine program development and in response, a specimen submission system was established, allowing agencies to submit Culex pipiens (L.) (Diptera:Culicidae) and Aedes albopictus (Skuse) (Diptera: Culicidae) for pesticide resistance testing. NEVBD also established larvicide resistance diagnostics for Bacillus thuringiensis israelensis (Bti) and methoprene. Additional diagnostics were developed for Cx. pipiens resistance to Lysinibacillus sphaericus. We received 58 survey responses, representing at least one agency from each of the 13 northeastern U.S. states. Results indicated that larvicides were deployed more frequently than adulticides, but rarely paired with resistance monitoring. Over 18,000 mosquitoes were tested from six states. Widespread low-level (1 × LC-99) methoprene resistance was detected in Cx. pipiens, but not in Ae. albopictus. No resistance to Bti or L. sphaericus was detected. Resistance to pyrethroids was detected in many locations for both species. Our results highlight the need for increased pesticide resistance testing in the United States and we provide guidance for building a centralized pesticide resistance testing program.

FRI0085 RETENTION RATE OF ADALIMUMAB AND ABP 501 IN THE TREATMENT OF A LARGE COHORT OF PATIENTS WITH INFLAMMATORY ARTHRITIS: A REAL LIFE RETROSPECTIVE ANALYSIS

Background:

The recent introduction of ABP 501, an adalimumab biosimilar, in treatment of rheumatic diseases was supported by a comprehensive comparability exercise with its originator. On the other hand observational studies comparing adalimumab and ABP 501 in inflammatory arthritis are still lacking.

Objectives:

To compare the clinical outcomes of the treatment with adalimumab, both originator and biosimilar, in a large cohort of patients affected by autoimmune arthritis in a real life setting.

Methods:

We retrospectively analysed the baseline characteristics and the retention rate in a cohort of patients who received at least a course of adalimumab (originator or biosimilar ABP 501) in eight Rheumatology Units from January 2003 to January 2020. We stratified the study population according to biosimilar use. Descriptive data are presented by medians (interquartile range [IQR]) for continuous data or as numbers (percentages) for categorical data. Drug survival distribution curves were computed by the Kaplan-Meier method and compared by a stratified log-rank test. P values ≤0.05 were considered statistically significant.

Results:

764 patients (53.4% female, median age 55 [44-65] years, median disease duration 60 [25-149] months) treated with adalimumab were included in the analysis. 308 (40.3%) were affect by rheumatoid arthritis, 244 (31.9%) by psoriatic arthritis, and 212 (27.7%) by axial spondylarthritis. 558 (73%) were treated with adalimumab originator and 206 (27%) with ABP 501. Among the biosimilars 60 (29.1%) patients were naïve to adalimumab treatment. The overall 6-month retentions rate was 93.1%. The 6-month retention rate for adalimumab and ABP 501 were 93.3% and 91.2% respectively, without significant differences between the groups (p=0.541). Patients switching from originator to biosimilar showed and overall higher treatment survival when compared to naive (6-month retention rate 95% vs 90-4%), although it was not significant (p=0.179).

Conclusion:

In our retrospective study adalimumab originator and its biosimilar ABP 501 showed the same effectiveness. Patients switching from originator to biosimilar showed an higher retention rate when compared to naive.

FRI0516 FACTORS ASSOCIATED WITH DECREASED CERVICAL CANCER SCREENING IN WOMEN WITH SYSTEMIC LUPUS ERYTHEMATOSUS

Background:

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that carries an increased risk for both viral illnesses and malignancies, including a greater risk for both human papilloma virus (HPV) infection and cervical cancer. Due to this increased risk, the American Society of Colposcopy and Cervical Pathology guidelines for SLE patients recommend more frequent cervical cancer screening. Few studies have examined patient characteristics associated with decreased cervical cancer screening in patients with autoimmune disease, specifically SLE.

Objectives:

To estimate cervical cancer screening rates in women with recently diagnosed SLE, and to identify characteristics associated with decreased screening.

Methods:

We identified women with an initial diagnosis of SLE in the United States MarketScan Commercial Claims and Encounter (CCAE, age 18-64) administrative claims database. We included patients with at least three claims with a lupus diagnosis (first and last at least >90 days apart), no lupus claims within the year before initial claim, and who had been on antimalarial drugs for at least 90 days. We excluded all patients with a previous claim for hysterectomy.

Cervical cancer screening was ascertained using diagnosis and procedure codes within 1 year before and 2 years after the first SLE claim. Our covariates included the year of first SLE claim (2001-2014), age at first SLE claim, comorbidity score, insurance type, geographical region, and prescriptions for multiple types of corticosteroids. Control patients included age-matched females without autoimmune disease. Univariate comparison and multivariate logistic regression models were built to evaluate determinants of screening.

Results:

We included 4,316 SLE patients (median age 45) and 86,544 control patients. The screening rate in SLE patients was 73.4% vs 58.5% in the controls (P < 0.001). The screening rate was 71% in 2001, increased to 75% in 2004, then decreased to 70% in 2014 (trend P =0.005). In the multivariate model the following factors were associated with decreased cervical cancer screening: year of first SLE claim 2012-2014 versus 2001-2005 (odds ratio (OR) 0.67, 95% confidence interval (CI) 0.53 – 0.84, P < 0.001); older age 61-64 versus 21-30 (OR 0.27, 95% CI 0.19 – 0.39, P < 0.001); comorbidity score of ≥2 versus <2 (OR 0.71, 95% CI 0.6 – 0.83, P < 0.001); and use of corticosteroids for ≥ 90 days versus <90 days (OR 0.73, 95% CI 0.59 – 0.9, P = 0.003). Insurance type and geographical region were not associated with cervical cancer screening.

Conclusion:

About three quarters of women with SLE underwent cervical cancer screening within 3 years of their first lupus claim, at higher rates than controls. However, there was a concerning downward trend in screening rates in recent years. In addition, higher risk populations for cervical cancer (older age, increased comorbidities, and longer duration of corticosteroids) had lower screening rates. These findings highlight the need to enhance education for healthcare providers to improve utilization of screening in women with SLE at high risk of cervical cancer.

Testing a novel biotechnological passive sampler for monitoring atmospheric PAH pollution

In this study we evaluated a new type of passive air sampler, the "mossphere" device, filled with a Sphagnum palustre clone. For this purpose, we compared the atmospheric levels of polyaromatic hydrocarbons (PAHs) collected using this device and those collected in conventional bulk deposition and particulate matter (PM10) samplers. All three types of samplers were exposed at 10 sites affected by different levels of pollution and located in two different climate zones. The bulk deposition/ mossphere comparison yielded a greater number of significant regressions with higher coefficients of determination than the PM10/ mossphere comparison. No significant regressions were observed for 3-ring PAHs in either comparison. The mosspheres explain ca. 50% of the variability of the concentrations of 4-, 5- and 6-ring PAHs and total PAHs detected in PM10 and ca. 70% of the corresponding concentrations detected in the bulk deposition. The use of the Sphagnum clone enables standardization of the set-up, thus making the mossphere device a good sampling tool for monitoring 4-, 5- and 6-ring and total PAHs, especially those associated with bulk deposition. The findings indicate the potential usefulness of this innovative technology for mapping PAH levels.

Indoor vs. outdoor airborne element array: A novel approach using moss bags to explore possible pollution sources

This study investigated by the moss-bag approach the pattern of air dispersed elements in 12 coupled indoor/outdoor exposure sites, all located in urban and rural residential areas. The aims were to discriminate indoor vs. outdoor element composition in coupled exposure sites and find possible relation between moss elemental profile and specific characteristics of each exposure site. Elements were considered enriched when in 60% of the sites, post-exposure concentration exceeded pre-exposure concentration plus two folds the standard deviation. Of the 53 analyzed elements, 15 (As, B, Ca, Co, Cr, Cu, Mn, Mo, Ni, Sb, Se, Sn, Sr, V, Zn) were enriched in moss exposed outdoor, whereas a subset of 7 elements (As, B, Cr, Mo, Ni, Se, V) were enriched also in indoor moss samples. The cluster analysis of the sites based on all elements, clearly separated samples in two groups corresponding to mosses exposed indoor and outdoor, with the latter generally exceeding the first. Among outdoor sites, urban were most impacted than rural; whereas other factors (e.g., heating and cooking systems, building material, residence time and family life style) could affect element profile of indoor environments. Based on the indoor/outdoor ratio, As derived from outdoor and indoor sources, B, Mo and Se were enriched mostly in outdoor sites; Ni, Cr and V were specifically enriched in most indoor samples, supporting the presence of indoor emitting sources for these elements. A PCA of all indoor sites based on enriched elements and site characteristics showed that traffic affected indoor pollution in urban areas. The moss bag approach provided useful information for a global assessment of human exposure.

Ligasure impact™might reduce blood loss, complications, and re-operation occurrence after abdominoplasty in massive-weight-loss patients: A Comparative Study

Background and Aims:

The most effective dissection technique for raising the flap in abdominoplasty is still controversial, particularly in high-risk massive-weight-loss patients. LigaSure Impact™vessel-sealing system (Medtronic, Dublin, Ireland) is an energy device commonly used among different surgical specialties to reduce morbidity and implement outcomes. The aim of this study was to investigate the effectiveness of LigaSure Impact in abdominoplasty compared with the conventional techniques, diathermia.

Material and Methods:

Patients underwent primary abdominoplasty after massive weight loss at a single center from 1 January 2008 to 31 May 2015 and were retrospectively reviewed. A total of 94 patients eligible for the study were divided into two groups on basis of the dissection technique: LigaSure Impact group (29 patients) and the conventional technique group (65 patients). Total intraoperative blood loss was the primary endpoint. Duration of the operation, perioperative complications and re-operation were recorded as secondary endpoints.

Results:

Baseline characteristics were well balanced between the groups. Significant differences were found in intraoperative blood loss favoring LigaSure Impact group (259.6 ± 198.8 mL vs 377.9 ± 190.0 mL, p = 0.004) and blood transfusion rates (13.8% vs 35.4%, p = 0.047). In contrast, operative time was significantly longer in LigaSure Impact group (168.6 ± 121.2 vs 179.7 ± 57.6 min, p = 0.005), while a tendency to shorter hospital stay was found in LigaSure Impact group (3.6 ± 1.1 days vs 4.6 ± 3.2 days, p = 0.081). Overall complications occurrence, Clavien–Dindo grade II (24.1% vs 55.4%) and grade III (13.8% vs 30.8%) complications were significantly lower in LigaSure Impact group (respectively, p = 0.005, p = 0.007, p = 0.016). Late (>30 days) re-operation rate was significantly lower in the LigaSure Impact group (6.9% vs 27.70%, p = 0.0028). Specific wound complications showed no significant difference.

Conclusion:

LigaSure Impact vessel-sealing system may be beneficial in improving abdominoplasty outcomes in massive-weight-loss patients because it might reduce blood loss, need for transfusions, complications, and re-operations.

Platelet-rich plasma versus hyaluronic acid injections for knee osteoarthritis: a propensity-score analysis

BACKGROUND AND AIMS

Intra-articular injections of viscosupplements have been an option in the treatment of knee osteoarthritis. Platelet-rich plasma is an experimental treatment in osteoarthritis. Previous studies have shown that platelet-rich plasma reduces osteoarthritis symptoms in similar proportions as viscosupplements. The aim of this study was to compare platelet-rich plasma versus viscosupplements in terms of symptoms' relief and time to arthroplasty.

MATERIAL AND METHODS

A total of 190 patients included in this retrospective study received either intra-articular injections of platelet-rich plasma (94 patients) or hyaluronic acid (86 patients) between January 2014 and October 2017. Western Ontario and McMaster Universities Osteoarthritis Index, Visual Analogue Scale, and range of motion were measured before injection, at 15 days, 6 months, 12 months, and at last follow-up. We compared outcomes between these two groups using propensity score analysis for risk adjustment in multivariate analysis and for one-to-one matching.

RESULTS

Hyaluronic acid-treated patients experienced a higher arthroplasty rate (36.0% vs 5.3%, p < 0.001), lower range of motion, worse Visual Analogue Scale and Western Ontario and McMaster Universities Osteoarthritis Index scores, and increased risk of any arthroplasty occurrence (log-rank < 0.001) than platelet-rich plasma patients. Cox proportional hazards analysis revealed a tendency to decrease the risk of knee arthroplasty for the patients treated by platelet-rich plasma (hazard ratio = 0.23, 95% confidence interval, 0.05-1.05, p = 0.058). When the treatment method was adjusted for propensity score in the propensity score-matched pairs (n = 78), we found that platelet-rich plasma group still showed significant improvement over the hyaluronic acid group in arthroplasty rate (12.8% vs 41.0%, p = 0.010), Visual Analogue Scale and Western Ontario and McMaster Universities Osteoarthritis Index scores, but not in the range of motion, during the mean follow-up of 16.7 months.

CONCLUSION

Intra-articular injections of platelet-rich plasma associated with better outcomes than hyaluronic acid in knee osteoarthritis. Platelet-rich plasma might prolong the time to arthroplasty and provide a valid therapeutic option in selected patients with knee osteoarthritis not responding to conventional treatments. Further larger studies are needed to validate this promising treatment modality.

Hypovitaminosis D: comparison between patients with hip fracture and patients with vertebral fractures

This study analyses the difference in 25OH-vitamin D values between two groups of patients both affected by severe osteoporosis with fragility fractures, but one group has vertebral fractures and the other one has hip fractures. Patients with hip fractures have vitamin D values lower than patients with vertebral fractures.

INTRODUCTION

The purpose of this study was to evaluate 25OHD levels in patients with fragility vertebral fractures (VF) and hip fractures (HF) and make a comparison between the groups.

METHODS

In the first group were enrolled ambulatory patients with 3 or more moderate to severe VF; in the second group were enrolled patients hospitalized in the Department of Orthogeriatrics undergoing surgery for HF. For all patients, we collected values of 25OHD and PTH. The group of patients with VF was further subdivided into pre-existing VF or recent VF treated within 30 days with vertebroplasty.

RESULTS

The sample consists of 180 subjects divided into two groups: 90 with VF and 90 with HF. The average value of 25OHD in the total sample was 13.2 ± 9.6 ng/ml, Vitamin D was significantly lower in the HF group than the VF group (p < 0.001)(VF 18.6 ± 9.7 ng/ml, HF 7.9 ± 5.7 ng/ml). The mean PTH value in the total sample was 67.5 ± 54.9 pg/ml and PTH was significantly higher in the HF group compared to the group with VF (p < 0.001) (VF 55.6 ± 27.2 pg/ml, HF 78.7 ± 70.2 pg/ml). The mean 25OHD value in the recent VF group is 16.0 ± 6.6 ng/ml while in the pre-existing VF group is 19.5 ± 10.4 ng/ml with a statistically significant difference (p < 0.001).

CONCLUSIONS

Patients of the same age with severe osteoporosis have a lower 25OHD value when the fracture occur at the hip and is recent, probably this is due to the inflammation caused by fracture and/or surgical intervention.

Geochemistry and carbon isotopic ratio for assessment of PM10 composition, source and seasonal trends in urban environment

Investigating the nature of PM₁₀ is crucial to differentiate sources and their relative contributions. In this study we compared the levels, and the chemical and mineralogical properties of PM₁₀ particles sampled in different seasons at monitoring stations representative of urban background, urban traffic and suburban traffic areas of Naples city. The aims were to relate the PM₁₀ load and characteristics to the location of the monitoring stations, to investigate the different sources contributing to PM₁₀ and to highlight PM₁₀ seasonal variability. Bulk analyses of chemical species in the PM₁₀ fraction included total carbon and nitrogen, δ¹³C and other 20 elements. Both natural and anthropogenic sources were found to contribute to the exceedances of the EU PM₁₀ limit values. The natural contribution was mainly related to marine aerosols and soil dust, as highlighted by X-ray diffractometry and SEM-EDS microscopy. The percentage of total carbon suggested a higher contribution of biogenic components to PM₁₀ in spring. However, this result was not supported by the δ¹³C values which were seasonally homogeneous and not sufficient to extract single emission sources. No significant differences, in terms of PM₁₀ load and chemistry, were observed between monitoring stations with different locations, suggesting a homogeneous distribution of PM₁₀ on the studied area in all seasons. The anthropogenic contribution to PM₁₀ seemed to dominate in all sites and seasons with vehicular traffic acting as a main source mostly by generation of non-exhaust emissions Our findings reinforce the need to focus more on the analysis of PM₁₀ in terms of quality than of load, to reconsider the criteria for the classification and the spatial distribution of the monitoring stations within urban and suburban areas, with a special attention to the background location, and to emphasize all the policies promoting sustainable mobility and reduction of both exhaust and not-exhaust traffic-related emissions.

Evidence on the effectiveness of mosses for biomonitoring of microplastics in fresh water environment

Mosses are well known as biomonitors of fresh water for metal pollutants, but no studies were reported so far about their ability to intercept plastic particles, although this kind of pollution has become an urgent issue worldwide. In the present work, the interaction between the moss Sphagnum palustre L. cultured in vitro and polystyrene nanoparticles (NPs) was studied for the first time in a laboratory experiment, in the view of using moss transplants for detecting microplastics in fresh water environments. The ability of S. palustre to intercept and retain polystyrene, and the effects of vitality and post-exposure washing on NP retention by moss were tested. Fluorescence microscope observations showed that polystyrene NPs were retained by moss leaves in form of small (the most abundant fraction) and large aggregates. Particle count analysis highlighted that the number of particles increased while increasing the exposure time. Moreover, moss devitalization favored NP accumulation, likely because of cell membrane damages occurred in dead moss material. Post-exposure washing induced a loss of larger aggregates, suggesting that exposure time is a key point to be carefully evaluated in field conditions. These results encourage the use of S. palustre transplants for monitoring microplastics contamination of fresh water environments.

Performance of three cardoon cultivars in an industrial heavy metal-contaminated soil: Effects on morphology, cytology and photosynthesis

In the present work the cytomorphological and physiological effects on three cardoon cultivars - Sardo, Siciliano, Spagnolo - grown in a metal-polluted soil, were investigated, to assess the traits concurring to the high tolerance to metal stress observed in cv. Spagnolo compared to the other two cultivars. The plants were grown for one month on a real polluted soil collected at a dismantling battery plant, highly enriched by heavy metals, especially Cd and Pb, and their leaves were analyzed by a multidisciplinary approach. TEM observations highlighted severe ultrastructural damage in Sardo and Siciliano, and preserved cytological traits in Spagnolo. Both pigment content and photochemistry indicated a decline in photosynthesis in Sardo and Sicilano and a substantial stability of the same parameters in Spagnolo. Protein analysis indicated a decrease in D1 level in all cultivars; in Spagnolo the D1 decrease was more pronounced and associated to a significant increase in Rubisco, a pattern likely preserving photosynthetic efficiency and high biomass production. In conclusion, Spagnolo cardoon was able to face metal stress through a prompt, multiple response balancing structural and functional traits.

Abstract PD7-12: Molecular subtyping of male breast cancer by the International male breast cancer program (IMBC): EORTC 10085/TBCRC 0-29/BIG 2-07/NABCG/BOOG 2009-04

Introduction. Male breast cancer (male BC) is a rare disease for which disease management is extrapolated from females. IMBC, an international consortium, which previously reported on clinico-pathological aspects, now reports on molecular subgroups revealed by RNA sequencing and their relation to patient outcome.

Methods. Tumor samples from the retrospective MALE BC registry diagnosed between 1990-2010 and with pathology and outcome data (relapse-free- (RFS) and overall survival (OS)) were included (n=699). To allow the discovery of prognostic features, we selected, stratified for known risk factors (TN stage, grade, age at diagnose and adjuvant endocrine treatment), from the cohort 152 cases with poor (RFS &lt;= 4 yrs) and good outcome (RFS &gt; 7yrs) evenly distributed. Here, we report RNA sequencing results of the first 73 cases, 38 with poor and 35 with good outcome. RNA sequencing reads were used to generate gene expression values and to report transcripts carrying driver mutations. Unsupervised clustering identified subgroups and within subgroups differentially expressed genes were identified. The reported prognostic male BC subgroups M1 and M2 (Johansson BCR 2012(14):R31) were also annotated. All identified subgroups were related to outcome using logistic regression (p-value using Wald test).

Results. Unsupervised clustering revealed 2 main subgroups of which group 1 was enriched for expression of ER target genes, WNT3 and genes from amplicons known for female BC, e.g. 19p13 (CCNE1), 8q24 (MYC), and 11q13 (CCND1). The biology of the smaller group 2 was less defined but TGFβ2 expression was high as were various kallikreins (KLK) including interestingly KLK3 (prostate specific antigen). Other known amplified regions [(8p11 (FGFR1), 20q13 (ZNF217) and 12q15 (MDM2)] and mutated transcripts [PIK3CA (H1047R/L/Q; E542K, E545K, N345K; 16% of cases), TP53 and SF3B1 (K700E) (2% of cases)] were identified. Profound tumor infiltrate gene expression was present in 5% of cases and one third of cases expressed proliferation markers. Except for TP53, none of these latter characteristics were unevenly distributed among the 2 main subgroups. ER and AR were highly correlated, particularly in group 1. The two main groups could be further subdivided. Group 1 comprised 3 subgroups of which subgroup 1a expressed TFF1/3 and NAT1, well-known ER targets, while subgroups 1b and 1c expressed other ER targets,respectively BEX1 and PITX1. HOXC cluster expression differentiated subgroup 1b from 1a and 1c. None of these intrinsic subgroups were, however, related to RFS. The previously reported M2 subgroup, which largely segregated with subclusters 1a and 1b, was associated with a better RFS than the M1 subgroup (OR=2.9; 95%CI 1.1-7.5; p-value=0.03).

Conclusions. 1) Intrinsic subtypes of male BC were revealed and their subgrouping is defined by ER associated subsets of genes. 2) The association of the reported M2 subgroup of male BC with longer RFS was validated; 3) Currently identified biological characteristics of male BC may improve future treatments. The full report on 152 cases including a comparison to female BC will be presented at the conference.

Ultrastructural, protein and photosynthetic alterations induced by Pb and Cd in Cynara cardunculus L., and its potential for phytoremediation

The effects of cadmium and lead were investigated in Cynara cardunculus L. Plant uptake by root and shoot, changes in cell ultrastructure and photosynthetic efficiency, photosynthetic key protein levels, as well as regulation of stress-induced Hsp70 were examined. Cynara cardunculus accumulated Cd and Pb in their tissue, with a different trend for the two metals. The prompt translocation of Cd to the shoot may justify the ultrastructural injuries, especially observed in chloroplasts. However, Cd- treated plants did not show any decline in photochemistry; it is likely that Cd in shoot tissue triggers defense mechanisms, increasing the level of proteins involved in photosynthesis (i.e., Rubisco and D1 increased 7 and 4.5 fold respectively) as a compensatory response to neutralize chloroplast damage. The accumulation of Pb mainly in root, can explain the increase in Hsp70 level (23 folds) in this tissue. Pb reached the shoots, even at low amounts, causing an overall significant change in some photochemical parameters (QY and NPQ decreases and increases of 25%, respectively). The results suggest a higher sensitivity of C. cardunculus to Pb than Cd, although maximal photochemical efficiency suggests that this species seems to tolerate Pb and Cd and hence, it is a suitable candidate for phytoremediation.

Laparoscopic Roux-En-Y Gastric Bypass in Elderly Patients (60 Years or Older): A Meta-Analysis of Comparative Studies

Background and Aims:

Elderly patient might experience an increased risk of complications after laparoscopic Roux-en-Y gastric bypass. We aimed to perform a meta-analysis of comparative studies on this issue in patients aged 60 years or older.

Material and Methods:

A systematic literature search was performed. Medline, Cochrane Library, Embase, Scopus, and Google Scholar were searched until July 2016 for studies on outcomes of laparoscopic Roux-en-Y gastric bypass in elderly versus younger patients. Primary outcomes were mortality and overall complications. Secondary outcomes were length of hospital stay, excess weight loss percentage, effect on diabetes, hypertension, hyperlipidemia and obstructive sleep apnea. Heterogeneity across the studies was evaluated by the I2 test, and a random effects model was used. Results were expressed as mean difference and risk ratio (RR).

Results:

Seven studies involving 3128 patients were retrieved and included in this study. A significantly increased risk of mortality and overall complications was observed among patients older than 60 years compared with younger ones (RR, 6.12; 95% confidence interval 1.08–34.83; p = 0.04; RR, 1.51; 95% confidence interval 1.07–2.11; p = 0.02). Particularly, elderly patients experienced 1% increased risk of mortality and 3% increased risk of overall complications. Length of stay, diabetes, and obstructive sleep apnea remission rates were similar among the groups. Excess weight loss percentage was significantly greater among younger patients (mean difference, −3.44; 95% confidence interval −5.20, −1.68; p < 0.001), as were hypertension (RR, 0.57; 95% confidence interval 0.42–0.76; p < 0.001) and hyperlipidemia (RR, 0.61; 95% confidence interval 0.45–0.83; p = 0.002) remission rates.

Conclusion:

Laparoscopic Roux-en-Y gastric bypass in patients older than 60 years may be a risky bariatric surgery operation due to higher complications and mortality and may not be as effective as in patients younger than 60 years. Thus, older patients should be carefully counseled before this procedure for individual risk–benefit assessment.

Sphagnum palustre clone vs native Pseudoscleropodium purum: A first trial in the field to validate the future of the moss bag technique

Although a large body of literature exists on the use of transplanted mosses for biomonitoring of air pollution, no article has addressed so far the use and the accumulation performance of a cloned moss for this purpose. In this work, a direct comparison of metal accumulation between bags filled with a Sphagnum palustre L. clone or with native Pseudoscleropodium purum Hedw., one of the most used moss species in biomonitoring surveys, was investigated. The test was performed in sites with different atmospheric contamination levels selected in urban, industrial, agricultural and background areas of Italy and Spain. Among the eighteen elements investigated, S. palustre was significantly enriched in 10 elements (Al, Ba, Cr, Cu, Fe, Hg, Pb, Sr, V and Zn), while P. purum was enriched only in 6 elements (Al, Ba, Cu, Hg, Pb and Sr), and had a consistently lower uptake capacity than S. palustre. The clone proved to be more sensitive in terms of metal uptake and showed a better performance as a bioaccumulator, providing a higher accumulation signal and allowing a finer distinction among the different land uses and levels of pollution. The excellent uptake performance of the S. palustre clone compared to the native P. purum and its low and stable baseline elemental content, evidenced in this work, are key features for the improvement of the moss bag approach and its large scale application.

Abstract P1-09-21: Clinical evaluation of miR-100 as a predictor of endocrine-responsiveness in hormone-receptor positive breast cancer

Background: Micro RNAs (miRNAs) are short, non-coding RNA molecules that act as negative regulators of gene-expression, mainly at the post-transcriptional level. Alterations in miRNA functions have been implicated in a variety of human diseases, including cancer

We demonstrated that the ectopic expression of miR-100 in cancer stem cells (CSCs) derived from aggressive, basal-like BC (HRs and HER2 negative) caused loss of stemness and the acquisition of a hormone receptor positive and endocrine treatment sensitive phenotype (Petrelli et al, Oncotarget 6;2315-30, 2015). We therefore sought to study whether miR-100 is a determinant of the endocrine-responsive phenotype in HR-positive BC patients (pts).

Methods: Women with newly diagnosed, estrogen-receptor and/or progesterone-receptor positive, HER2 negative BC were eligible for this study. Treatment consisting of tamoxifen for pre-menopausal and letrozole for post-menopausal pts was administered daily for 21 days (+/- 3 days) before breast surgery. MiR-100 levels in pre-treatment tumor biopsies, measured as fold-change with respect to a reference RNA and transformed to the natural logarithms to normalize the data, were correlated with proliferative response to endocrine therapy, as measured by Ki67 expression in the final surgical specimen. The primary end-point was a complete proliferative response (CPR), defined as a post-treatment Ki67≤1%. Additionally, we considered a “post-hoc” composite endpoint where response was defined as a post treatment Ki67 &lt;10% together with a Ki67 reduction ≥80% compared to pre-treatment values. The target accrual is 88 patients (pts). Here we report the results of the first interim analysis focusing on post-menopausal pts receiving letrozole.

Results: A total of 42 pts were evaluable for miR-100 levels and response to endocrine therapy. Median ER and PgR expression was 99% (58%-99%) and 96% (0-99%) respectively. Median pre-treatment Ki67 was 18% (5-76%). Thirty-one tumors were ductal carcinomas, 9 were lobular and 2 were “other” histotypes. The median (range) miR-100 values in pre-treatment specimens was 2.253 (0.460-3.750). After treatment, median Ki67 was 4% (1%-46%) and the median percentage variation with respect to baseline values was -74% (0% to -94%). A CPR was observed in 5/42 pts (12%, 95% C.I. 5%-25%). The median miR-100 levels in responders and non-responders were 3.058 and 2.198, respectively (p = 0.03). Logistic regression analysis showed that each unit increase in miR-100 was associated with a 7-fold increase in the likelihood of a CPR (OR 7.056, 95% C.I. 1.103-45.141, p = 0.04).

Considering the composite end-point, 17/42 pts (40%, 95% C.I. 27%-56%) were considered responders. Median miR-100 levels in responders and non-responders were 2.427 and 1.956, respectively (p = 0.05).

Conclusions: preliminary results of this prospective clinical trial suggest that miR-100 can be a modulator of the endocrine-responsive phenotype in post-m pts with HR-positive breast cancer. The study is completing its target accrual and an investigation of miR-100 targets is being conducted.

Tracking the route of phenanthrene uptake in mosses: An experimental trial

In recent decades, mosses have been used as native species or as transplants in monitoring a wide range of pollutants from inorganic (i.e. metals and metalloids) to organic contaminants (mainly polycyclic aromatic hydrocarbons-PAHs). To implement the use of mosses as biomonitors of PAHs, one important issue is the study of the interactions between these compounds and moss tissues. In this study we investigated the mode of phenanthrene uptake in four moss species (Amblystegium humile, Plagiomnium affine, Hypnum cupressiforme and a clone of Sphagnum palustre) and its movements from air to plant surface and within the biomonitors, using fluorescent and confocal microscopy. The target compound, partitioned between gas and particulate phase depending on air conditions, was selected since it is one of the most abundant PAHs released into the atmosphere. Our findings support the hypothesis that phenanthrene aggregates in particles and in this form it is chiefly intercepted and uptaken onto moss surfaces, albeit with different frequency in the four species, with S. palustre>H. cupressiforme>P. affine=A. humile. Phenanthrene enters the dead, empty hyalocysts of S. palustre. Specific surface area and composition, frequency and distribution of binding groups may also explain the different ability of phenanthrene uptake by the four moss species.

Whole body PET/CT in the follow-up of asymptomatic patients with stage IIB-IIIB cutaneous melanoma. Acta Oncol 2016;55:1355-1359. [PMID: 27553064 DOI: 10.1080/0284186x.2016.1213879]

BACKGROUND

Whole body positron emission tomography (PET)/computed tomography (CT) is a sensitive imaging technique in patients with metastatic melanoma, but its role in the follow-up of asymptomatic high-risk patients is unclear. The aim was to study the role of PET/CT as a routine surveillance imaging tool in asymptomatic high-risk patients at the early stage of follow-up combined with a sufficient follow-up over several years.

MATERIAL AND METHODS

A total of 110 asymptomatic patients with clinically local American Joint Committee on Cancer (AJCC) stage IIB-IIIB melanoma underwent routine whole body PET/CT scanning after a mean interval of seven months after initial surgery. Clinical data were retrospectively analyzed after a median follow-up time of 4.6 years.

RESULTS

Recurrent melanoma was detected in 45 patients (41%) and 36 (33%) died of melanoma. In 11 asymptomatic patients (10%) occult disease was detected with a single PET/CT. In seven of these patients (64%), positive PET/CT finding had major influence in treatment decisions. Four patients underwent surgical metastasectomy and two of them remained disease-free. In 34 patients (31%) PET/CT revealed no disease, but recurrence was detected at a median time of 19 months after negative PET/CT scan. In 50 patients (45%) PET/CT finding was true negative. In 15 patients (14%) scan was false positive leading to additional management or repetitive imagings.

CONCLUSION

A single PET/CT could detect 24% of all recurrences in asymptomatic melanoma patients at the early stage of follow-up, but an earlier detection of occult metastases did not improve survival.

Best options for the exposure of traditional and innovative moss bags: A systematic evaluation in three European countries

To develop an internationally standardized protocol for the moss bag technique application, the research team participating in the FP7 European project "MOSSclone" focused on the optimization of the moss bags exposure in terms of bag characteristics (shape of the bags, mesh size, weight/surface ratio), duration and height of exposure by comparing traditional moss bags to a new concept bag, "Mossphere". In particular, the effects of each variable on the metal uptake from the air were evaluated by a systematic experimental design carried out in urban, industrial, agricultural and background areas of three European countries with oceanic, Mediterranean and continental climate. The results evidenced that the shape, the mesh size of the bags and the exposure height (in the tested ranges), did not significantly influence the uptake capacity of the transplanted moss. The aspects more affecting the element uptake were represented by the density of the moss inside the bags and the relative ratio between its weight and the surface area of the bag. We found that, the lower the density, the higher the uptake recorded. Moreover, three weeks of exposure were not enough to have a consistent uptake signal in all the environments tested, thus we suggest an exposure period not shorter than 6 weeks, which is appropriate in most situations. The above results were confirmed in all the countries and scenarios tested. The adoption of a shared exposure protocol by the research community is strongly recommended since it is a key aspect to make biomonitoring surveys directly comparable, also in view of its recognition as a monitoring method by the EU legislation.

Biomonitoring of atmospheric pollution by moss bags: Discriminating urban-rural structure in a fragmented landscape

In this paper we investigated the possibility to use moss bags to detect pollution inputs - metals, metalloids and polycyclic aromatic hydrocarbons (PAHs) - in sites chosen for their different land use (agricultural, urban/residential scenarios) and proximity to roads (sub-scenarios), in a fragmented conurbation of Campania (southern Italy). We focused on thirty-nine elements including rare earths. For most of them, moss uptake was higher in agricultural than in urban scenarios and in front road sites. Twenty PAHs were analyzed in a subset of agricultural sites; 4- and 5-ringed PAHs were the most abundant, particularly chrysene, fluoranthene and pyrene. Overall results indicated that investigated pollutants have a similar spatial distribution pattern over the entire study area, with road traffic and agricultural practices as the major diffuse pollution sources. Moss bags proved a very sensitive tool, able to discriminate between different land use scenarios and proximity to roads in a mixed rural-urban landscape.

Air pollution monitoring using emission inventories combined with the moss bag approach

Inventory of emission sources and biomonitoring with moss transplants are two different methods to evaluate air pollution. In this study, for the first time, both these approaches were simultaneously applied in five municipalities in Campania (southern Italy), deserving attention for health-oriented interventions as part of a National Interest Priority Site. The pollutants covered by the inventory were CO, NOx, particulate matter (PM10), volatile organic compounds (VOCs), and some heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb, Se, and Zn). The biomonitoring survey was based on the use of the devitalized moss Hypnum cupressiforme transplanted into bags, following a harmonized protocol. The exposure covered 40 agricultural and urban/residential sites, with half of them located in proximity to roads. The pollutants monitored were Al, As, Cd, Cr, Cu, Fe, Hg, Ni, Pb, Se, and Zn, as well as total polycyclic aromatic hydrocarbons (PAHs) only in five sites. Using the emission inventory approach, high emission loads were detected for all the major air pollutants and the following heavy metals: Cr, Cu, Ni, Pb and Zn, over the entire study area. Arsenic, Pb, and Zn were the elements most accumulated by moss. Total PAH postexposure contents were higher than the preexposure values (~20-50% of initial value). Moss uptakes did not differ substantially among municipalities or within exposure sites. In the five municipalities, a similar spatial pattern was evidenced for Pb by emission inventory and moss accumulation. Both approaches indicated the same most polluted municipality, suggesting their combined use as a valuable resource to reveal contaminants that are not routinely monitored.

Has racial difference in cause-specific death improved in older patients with late-stage breast cancer?

BACKGROUND

Research on temporal mortality trends for stage IV breast cancer is limited, especially among older patients by race. We evaluated factors associated with overall, breast cancer-specific and other-cause mortalities using contemporary population data.

PATIENTS AND METHODS

Using the Surveillance, Epidemiology, and End Results-Medicare linked data, we identified older women (≥ 66 years) with stage IV breast cancer diagnosed in 2002-2009. Overall mortality was estimated by the Kaplan-Meier method, compared by log-rank tests, and modeled by Cox models. Competing risk analysis was used to evaluate breast cancer-specific and other-cause mortalities.

RESULTS

The median overall survival time for non-Hispanic blacks improved from 8.6 months in 2002-2003 to 9.9 months in 2007-2009, whereas that for non-Hispanic whites improved from 12.1 to 14.8 months. In the multivariate model, the risk of breast cancer-specific death for patients diagnosed in 2007-2009 was significantly lower (P = 0.02), whereas the risk of other-cause mortality changed little (P = 0.88) compared with those risks for patients diagnosed in 2002-2003. Non-Hispanic blacks had the higher risk of both mortality types compared with non-Hispanic whites; a diagnosis time-race interaction term was not statistically significant for either cause of death.

CONCLUSION

Breast cancer-specific mortality among older women modestly improved from 2002 to 2009 across all races, but not other-cause mortality. Racial disparity in mortality persisted, but did not widen in this period. Efforts should be devoted to improving other-cause mortality for all women, with special attention toward decreasing breast cancer mortality for non-Hispanic black women.

A single postdischarge telephone call by an occupational therapist does not reduce the risk of falling in women after hip fracture: a randomized controlled trial

BACKGROUND

Post-discharge telephone calls to reinforce targeted recommendations for fall prevention have scarcely been investigated in hip-fracture survivors.

AIM

To assess the effectiveness of a single telephone call by an occupational therapist in reducing the proportion of fallers (primary endpoint) and improving the adherence to targeted recommendations for fall prevention (secondary endpoint) after hospital discharge in hip-fracture women.

DESIGN

Randomized controlled trial.

SETTING

Post-acute rehabilitation hospital and community (post-discharge).

POPULATION

We randomized 169 of 228 women with a fall-related fracture of the hip. Data for analyses were available for 153 women (78 from the intervention group and 75 controls).

METHODS

All the women underwent a multidisciplinary program targeted at fall prevention during post-acute inpatient rehabilitation. Additionally, the intervention group received a telephone call by an occupational therapist to reinforce the targeted recommendations for fall prevention at a median of 18 days after discharge. The outcomes were assessed at a six-month follow-up.

RESULTS

Eleven of the 78 women (14.1%) from the intervention group, and 10 of the 75 (13.3%) from the controls sustained at least one fall during the follow-up (relative risk=1.06; 95% CI from 0.48 to 2.34). The mean adherence to the recommendations for fall prevention was 75.1% in the intervention group and 71.2% in the controls (between group difference 3.9; 95% CI from -3.4 to 11.3; P=0.29).

CONCLUSION

Our study does not support a post-discharge telephone call to reinforce the recommendations for fall prevention in hip-fracture women.

CLINICAL REHABILITATION IMPACT

We contribute to elucidate one aspect of multidisciplinary fall-prevention strategies in hip-fracture survivors.

Laparoscopic Roux-en-Y gastric bypass versus laparoscopic adjustable gastric banding in the super-obese: peri-operative and early outcomes

INTRODUCTION

Controversy exists between laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding in super-obese patients.

METHODS

This is a retrospective review of prospectively collected data. A total of 102 consecutive super-obese (body mass index >50) patients underwent laparoscopic Roux-en-Y gastric bypass (Group 1), and 79 consecutive ones underwent laparoscopic adjustable gastric banding (Group 2). Early complications and weight loss outcomes were evaluated.

RESULTS

No significant difference was found in operative mean (± standard deviation) time (93.5 ± 33 vs 87.7 ± 39 min, p = 0.29), hospital stay (2.68 ± 2.27 vs 2.75 ± 1.84 days, p = 0.80), or overall early postoperative morbidity (17.65% and 10.12%, p = 0.20). Intra-operative complications occurred in six patients (5.9%) in Group 1 and none in Group 2 (0.0%, p = 0.04). Mean excess weight loss percent at 6 and 12 months in Group 1 was 44.75% ± 11.84% and 54.71% ± 18.18% versus 26.20% ± 12.42% and 31.55% ± 19.79% in Group 2 (p < 0.001).

CONCLUSION

There seems to be no significant differences in early complications between laparoscopic Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding operations in the short term. Weight loss and excess weight loss percent at 6 and 12 months are significantly better after laparoscopic Roux-en-Y gastric bypass.

Medical treatment in gender dysphoric adolescents endorsed by SIAMS-SIE-SIEDP-ONIG

PURPOSE

Despite international guidelines being available, not all gender clinics are able to face gender dysphoric (GD) youth population needs specifically. This is particularly true in Italy. Centers offering specialized support are relatively few and a commonly accepted Italian approach to GD youth has still not been defined. The aim of the present Position Statement is to develop and adhere to Italian guidelines for treatment of GD adolescents, in line with the "Dutch Approach", the Endocrine Society (ES), and the World Professional Association for Transgender Health (WPATH) guidelines.

METHODS

An in-depth brainstorming on the application of International guidelines in the Italian context was performed by several dedicated professionals.

RESULTS

A staged approach, combining psychological support as well as medical intervention is suggested. In the first phase, individuals requesting medical help will undergo a psycho-diagnostic procedure to assess GD; for eligible adolescents, pubertal suppression should be made available (extended diagnostic phase). Finally, from the age of 16 years, cross-sex hormonal therapy can be added, and from the age of 18 years, surgical sex reassignment can eventually be performed.

CONCLUSIONS

The current inadequacy of Italian services offering specialized support for GD youth may lead to negative consequences. Omitting or delaying treatment is not a neutral option. In fact, some GD adolescents may develop psychiatric problems, suicidality, and social marginalization. With access to specialized GD services, emotional problems, as well as self-harming behavior, may decrease and general functioning may significantly improve. In particular, puberty suppression seems to be beneficial for GD adolescents by relieving their acute suffering and distress and thus improving their quality of life.
