RESUMO

Cognitive and affective impairments in processing body image have been observed in patients with Anorexia Nervosa (AN) and may induce the hypercontrolled and regulative behaviors observed in this disorder. Here, we aimed to probe the link between activation of body representations and cognitive control by investigating the ability to resolve body-related representational conflicts in women with restrictive AN and matched healthy controls (HC). Participants performed a modified version of the Flanker task in which underweight and overweight body images were presented as targets and distractors; a classic version of the task, with letters, was also administered as a control. The findings indicated that performance was better among the HC group in the task with bodies compared to the task with letters; however, no such facilitation was observed in AN patients, whose overall performance was poorer than that of the HC group in both tasks. In the task with body stimuli, performance among patients with AN was the worst on trials presenting underweight targets with overweight bodies as flankers. These results may reflect a dysfunctional association between the processing of body-related representations and cognitive control mechanisms that may aid clinicians in the development of optimal individualized treatments.

RESUMO

Daratumumab (DARA) is a human IgG-K monoclonal antibody (MoAb) targeting CD38 that is approved alone or in combination with bortezomib and dexamethasone or lenalidomide and dexamethasone for relapsed or refractory MM (RRMM) in patients previously exposed or double refractory to proteasome inhibitors (PI) and immunomodulatory drugs (IMiDs). However, there are limited data on its clinical activity and tolerability in real-world patients. Therefore, in the present study, we aim to determine the efficacy and toxicity profile of daratumumab in a real-life setting. In this study, we report the experience of the multiple myeloma GIMEMA Lazio Group in 62 relapsed/refractory MM patients treated with daratumumab as monotherapy who had previously received at least two treatment lines including a PI and an IMiDs or had been double refractory. Patients received DARA 16 mg/kg intravenously weekly for 8 weeks, every 2 weeks for 16 weeks, and every 4 weeks until disease progression or unacceptable toxicity. The overall response rate to daratumumab was 46%. Median progression-free survival (PFS) and overall survival reached 2.7 and 22.4 months, respectively. DARA was generally well tolerated; however, 2 patients interrupted their therapy due to adverse events. Present real-life experience confirms that DARA monotherapy is an effective strategy for heavily pre-treated and refractory patients with multiple myeloma, with a favorable safety profile.

RESUMO

BACKGROUND: RAS and K601E BRAF mutations are not a reliable indicator of malignancy in fine-needle aspirations (FNA) of thyroid indeterminate cytologic nodules. We aimed to evaluate the histologic characteristics, the risk of malignancy associated with such mutations in FNA and their potential interest for preoperative clinical management of nodules. METHODS: We evaluated 69 indeterminate thyroid nodules with RAS or K601E BRAF mutations with available histopathologic follow-up. All FNA specimens were indeterminate according to the thyroid Bethesda system. Diagnosis of malignant, benign or indolent neoplasms was classified according to 2017 WHO classification. Carcinoma, NIFTP (noninvasive follicular thyroid neoplasm with papillary-like features) and WDTUMP (well-differentiated tumor of uncertain malignant potential) were considered "surgical," as they require surgical excision. Adenoma was considered "non-surgical." The risk of malignancy and the risk of "surgical disease" were evaluated. RESULTS: Pathologic evaluation of the 69 mutated nodules demonstrated benign, indolent and malignant histology in 17 cases (25%), 21 cases (30%) and 31 cases (45%), respectively. The risk of malignancy was 45%, and the risk of surgical disease was 75%. The majority of carcinomas were a follicular variant of papillary thyroid carcinoma. On follow-up, there have been no recurrences to date. CONCLUSION: Preoperative RAS or BRAF K601E mutations detection in cytologic indeterminate thyroid nodules carries a high risk of surgical disease and may benefit from surgical management. Most surgical lesions harboring those mutations are low-risk tumors, which may be in favor of an initial lobectomy.

RESUMO

OBJECTIVES: Osteonecrosis of the jaw (ONJ) is a potentially severe adverse effect of bisphosphonates (BP). Although the risk of ONJ increases with increasing duration of BP treatment, there are currently no reliable estimates of the ONJ time to onset (TTO). The objective of this study was to estimate the TTO and associated risk factors in BP-treated patients. SUBJECTS AND METHODS: Retrospective analysis of data from 22 secondary care centres in seven countries relevant to 349 patients who developed BP-related ONJ between 2004 and 2012. RESULTS: The median (95%CI) TTO was 6.0 years in patients treated with alendronate (n = 88) and 2.2 years in those treated with zoledronate (n = 218). Multivariable Cox regression showed that dentoalveolar surgery was inversely associated, and the use of antiangiogenics directly associated, with the TTO in patients with cancer treated with zoledronate. CONCLUSIONS: The incidence of ONJ increases with the duration of BP therapy, with notable differences observed with respect to BP type and potency, route of administration and underlying disease. When data are stratified by BP type, a time of 6.0 and 2.2 years of oral alendronate and intravenous zoledronate therapy, respectively, is required for 50% of patients to develop ONJ. After stratification by disease, a time of 5.3 and 2.2 years of BP therapy is required for 50% of patients with osteoporosis and cancer, respectively, to develop ONJ. These findings have significant implications for the design of future clinical studies and the development of risk-reduction strategies aimed at either assessing or modulating the risk of ONJ associated with BP.

RESUMO

OBJECTIVE: Liquid-based (LB)-FNA is widely recognized as a reliable diagnostic method to evaluate thyroid nodules. However, up to 30% of LB-FNA remain indeterminate according to the Bethesda system. Use of molecular biomarkers has been recommended to improve its pathological accuracy but implementation of these tests in clinical practice may be difficult. Here, we evaluated feasibility and performance of molecular profiling in routine practice by testing LB-FNA for BRAF, N/HRAS and TERT mutations. METHODS: We studied a large prospective cohort of 326 cases, including 61 atypia of undetermined significance, 124 follicular neoplasms, 72 suspicious for malignancy and 69 malignant cases. Diagnosis of malignancy was confirmed by histology on paired surgical specimen. RESULTS: Mutated LB-FNAs were significantly associated with malignancy regardless of the cytological classification. Overall sensitivity was 60% and specificity 89%. Importantly, in atypia of undetermined significance and follicular neoplasm patients undergoing surgery according to the Bethesda guidelines, negative predictive values were 85.4% and 90% respectively. TERT promoter mutation was rare but very specific for malignancy (5.5%) suggesting that it could be of interest in patients with indeterminate cytology. CONCLUSIONS: Mutation profiling can be successfully performed on thyroid LB-FNA without any dedicated sample in a pathology laboratory. It is an easy way to improve diagnostic accuracy of routine LB-FNA and may help to better select patients for surgery and to avoid unnecessary thyroidectomies.

RESUMO

INTRODUCTION: The expression of menin in the thyroid gland has long been debated. Animal models with targeted inactivation of menin in the thyroid gland have shown that its inactivation might play a role in the progression to a more aggressive type of cancer. Human studies are conflicting, some have identified mutations in the MEN1 gene in a sub-type of oncocytic thyroid carcinomas, while others have not identified a higher prevalence of thyroid cancer in MEN1 patients. OBJECTIVE: To analyze the immunohistochemical expression of menin in different types of thyroid carcinomas. MATERIALS AND METHODS: 48 thyroid tumours (12 papillary thyroid carcinomas (PTC), 6 anaplastic thyroid carcinomas (ATC), 12 poorly differentiated thyroid carcinomas (PDTC), 5 medullary thyroid carcinomas (MTC), 5 oncocytic follicular carcinomas (OC), 3 oncocytic adenomas (OA) and 5 goiters (G)) were tested for nuclear expression of menin using an anti-menin antibody. The expression was considered positive, negative or decreased. RESULTS: The expression of menin was positive, identical to normal tissue, in 39 cases (81.25%). The expression was decreased (n=8) or absent (n=1) in 9 tumours (18.75% - 2 PTC, 5 PDTC, 2 OC) accounting for 42% (5/12) of the PDTC and 40% (2/5) of the OC. CONCLUSIONS: Our results show that the expression of menin is generally preserved in human thyroid carcinomas, but it can be decreased or absent in certain types of thyroid cancer. Further molecular studies are needed to evaluate to potential of menin protein in tumorigenesis.

RESUMO

We aimed at assessing the prevalence of peripheral neuropathy in newly diagnosed, treatment-naïve patients with multiple myeloma. We enrolled 153 patients with multiple myeloma at initial diagnosis. All patients underwent neurological examination and nerve conduction study. Patients with suspected pure small fiber neuropathy underwent skin biopsy. Of the 153 patients included in this study, 7.2 % had a multiple myeloma-related neuropathy. All patients suffered from a distal symmetric sensory peripheral neuropathy, associated with age (P = 0.04). Our study on prevalence rate of multiple myeloma-related peripheral neuropathy might provide a basis for improving the clinical management of this condition.

RESUMO

OBJECTIVE: Co-expression of p16INK4a protein and Ki-67 (p16/Ki-67) is noted in almost all high-grade urothelial lesions. However, the aetiological role or, conversely, the absence of causative effect of high-risk human papillomaviruses (hr-HPVs) has not been documented. The purpose of this study is to evaluate HPV DNA in p16/Ki-67-positive, high-grade urothelial tumour cells. METHODS: Fifty-seven urine samples collected from 50 patients, including 55 histologically proven high-grade proliferations and two cases with clinical evidence of malignancy, were analysed for p16/Ki-67. Immunolabelling was performed in destained Papanicolaou-stained slides after ThinPrep(®) processing. HPV genotyping was performed by polymerase chain reaction (PCR) using a DNA microarray for 35 HPV types. Confirmation of the presence (or absence) of HPV in tissue samples was verified using a reasoned approach combining PCR and in situ hybridization (ISH) for hr-HPVs. RESULTS: Co-expression of p16/Ki-67 was noted in 43 of 57 (75.4%) cases. In these, hr-HPVs 16, 31 and 70, and low risk HPV 84, were detected in the urine in four patients (8%). Upregulation of p16INK4a protein was confirmed on bladder biopsy or transurethral resection specimens, but PCR and ISH for hr-HPVs were both negative on the tissue sections. CONCLUSION: Our results show a low prevalence of HPV infection in the urinary tract of patients with p16/Ki-67-positive urothelial malignancy. The study confirms that the deregulated cell cycle, as demonstrated by p16/Ki-67 dual labelling, is independent of the oncogenic action of hr-HPVs in high-grade urothelial proliferations.

RESUMO

AIM: To evaluate the performance of urinary PCA3 test to predict prostate biopsy outcome in a large French cohort. PATIENTS AND METHODS: A urine sample was prospectively obtained in 1015 patients undergoing prostate biopsies to determine the PCA3 score. The predictive value of PCA3 was explored using receiver operating characteristic curve analysis (ROC), multivariable logistic regression analysis and decision curve analysis. RESULTS: The median PCA3 score was significantly higher in patients with positive biopsies. The PCA3 score AUC was 0.76 (0.73-0.79), significantly higher than that of PSA (0.55; 0.51-0.58). At the cut-off of 35, sensitivity was 68 %, specificity 71 %, positive and negative predictive values 67 % and 71 %, and accuracy 69 %. Using multivariate analysis, PCA3 score appeared as an independent predictor of biopsy outcome and its addition to a base model including usual clinico-biological parameters resulted in a significant increase in predictive accuracy. At the cut-off of 20, about 1/2 of the eventual useless biopsies would have been avoided while ignoring 7 % of cancers with Gleason score ≥ 7. PCA3 score did not correlate to Gleason score but correlated to tumor volume (proportion of invaded cores). CONCLUSION: Urinary PCA3 is a useful test with high diagnostic performance for early prostate cancer diagnosis. Its correlation with cancer aggressiveness seems rather represented by a link to prostate volume than Gleason score.

RESUMO

OBJECTIVE: We studied whether atypical, non-superficial urothelial cells (AUC) could be separated into new subcategories including AUC 'of undetermined significance' (AUC-US) and 'cannot exclude high grade'' (AUC-H) in order to help to standardize urine cytopathology reports, as it is widely accepted in the Bethesda system for gynaecological cytopathology. METHODS: We investigated whether AUC-US and AUC-H, defined by distinctive cytological criteria, might be separated with statistical significance according to actual diagnosis and follow-up data. A series of 534 cyto-histological comparisons taken in 139 patients, including 221 AUC at various steps of their clinical history was studied. There were 513 (96.1%) postcystoscopy and 469 (87.8%) ThinPrep® liquid-based specimens (95.9% and 89.1% of AUC cases, respectively). Patients viewed between 1999 and 2011 had histological control in a 0- to 6-months delay and were followed-up during an additional 5.9 ± 9.2 (0- to 56-) months period. RESULTS: The 221 AUC represented 0.8-2% of the specimens viewed during the study period. Among AUC-H cases, 70 out of 185 (37.8%) matched with high-grade lesions, compared with 3 of 38 (8.3%) of AUC-US cases (P = 0.0003). Conservatively treated patients with AUC-H more frequently developed high-grade lesions than those with AUC-US (54.1% versus 16.7%, P = 0.0007) with a 17.6-months mean delay. Nuclear hyperchromasia, a nuclear to cytoplasm (N/C) ratio > 0.7 and the combination of both were the more informative diagnostic criteria, all with P < 0.01. CONCLUSION: We conclude that the new subcategories could help to standardize urine cytopathology reports and contribute to the patient's management, provided it is validated by multicentric studies.

RESUMO

To investigate the risk of developing multiple primary cancers (MPCs) in patients with previous gynaecological malignancies (cervical, uterine, and ovarian). The study's subjects included all the women on the Umbrian Cancer Registry who were first diagnosed with gynaecological cancer between 1994 and 2009. MPCs were defined according to the rules defined by International Association of Cancer Registries (IACR) and International Agency for Research on Cancer (IARC). Standardized incidence ratios (SIRs) of observed to expected cases were used as the measure of relative risk; its significance and 95% confidence intervals were determined assuming a Pois- son distribution. During the analysed period, the authors observed a total of 346 cases of MPCs in women with cervix (54 cases), corpus of uterus (196 cases), and ovarian (96 cases) malignancies. Significant SIRs were found in all of them, considering all sites combined: 2.43 (95% CI: 1.87-3.14) for cervix, 1.75 (95% CI: 1.52-2.01) for corpus of uterus, and 2.32 (95% CI: 1.90-2.84) for ovary malignancies, with different site-specific risks. Current data confirmed an excess risk of MPCs among women with gynaecological malignancies compared to the general population. The observed site-specific associations are useful to investigate shared risk factors and set up specific follow-up patients.

RESUMO

Background: Freezing of gait (FOG) is a debilitating symptom of Parkinson's disease (PD) that is often refractory to medication. Pathological prolonged beta bursts within the subthalamic nucleus (STN) are associated with both worse impairment and freezing behavior in PD, which are improved with deep brain stimulation (DBS). The goal of the current study was to investigate the feasibility, safety, and tolerability of beta burst-driven adaptive DBS (aDBS) for FOG in PD. Methods: Seven individuals with PD were implanted with the investigational Summit™ RC+S DBS system (Medtronic, PLC) with leads placed bilaterally in the STN. A PC-in-the-loop architecture was used to adjust stimulation amplitude in real-time based on the observed beta burst durations in the STN. Participants performed either a harnessed stepping-in-place task or a free walking turning and barrier course, as well as clinical motor assessments and instrumented measures of bradykinesia, OFF stimulation, on aDBS, continuous DBS (cDBS), or random intermittent DBS (iDBS). Results: Beta burst driven aDBS was successfully implemented and deemed safe and tolerable in all seven participants. Gait metrics such as overall percent time freezing and mean peak shank angular velocity improved from OFF to aDBS and showed similar efficacy as cDBS. Similar improvements were also seen for overall clinical motor impairment, including tremor, as well as quantitative metrics of bradykinesia. Conclusion: Beta burst driven adaptive DBS was feasible, safe, and tolerable in individuals with PD with gait impairment and FOG.

RESUMO

OBJECTIVE: Overexpression of p16(INK4a) independent of the presence of E6-E7 oncoproteins of high-risk papillomaviruses has been identified in bladder carcinoma in situ lesions with or without concurrent papillary or invasive high-grade (HG) urothelial carcinoma. As p16(INK4a) and Ki-67 co-expression clearly indicates deregulation of the cell cycle, the aim of this study was to investigate the frequency of p16(INK4a) /Ki-67 dual labelling in urinary cytology samples. METHODS: Immunolabelling was performed in demounted, destained Papanicolaou slides after ThinPrep(®) processing. A total of 84 urinary cytology samples (18 negative, 10 low grade, 19 atypical urothelial cells and 37 high grade) were analysed for p16(INK4a) /Ki-67 co-expression. We assessed underlying urothelial malignancy with cystoscopy, histopathology and follow-up data in every case. RESULTS: Compared with raw histopathological results, p16 (INK4a) /Ki-67 dual labelling was observed in 48 out of 55 (87.3%) HG lesions and in 11 out of 29 (37.9%) negative, papillary urothelial neoplasia of low malignant potential or low-grade carcinomas (P = 0.05). All cases with high-grade/malignant cytology were dual labelled. Sixteen out of 17 (94.1%) carcinoma in situ cases and eight out of 14 (57.1%) cases with atypical urothelial cells matching with HG lesions were dual labelled. Extended follow-up allowed three cases of progression to be diagnosed in dual-labelled cases with negative/low-grade cytology results after a 9- to 11-months delay. CONCLUSIONS: The data show that p16(INK4a) /Ki-67 co-expression allows most HG cancer cells to be detected initially and in the follow-up period. Additional studies are needed in order to determine whether dual labelling can be used as a triage tool for atypical urothelial cells in the urine.

RESUMO

The authors describe the incidence and mortality rates of human papillomavirus (HPV)-related female cancers in Umbria (Italy) in the pre-vaccination period from 1978-2008. Joinpoint regression was applied on age-adjusted incidence and mortality rates to evaluate temporal trends. Mouth and pharynx cancers incidence and mortality trends decreased about three percent per year. For anus and anal canal cancer, incidence and mortality trends presented a non-significant decrease. For malignant neoplasm of vulva, a significant change was found in incidence trend: the annual percentage change decreased from 2001 (- 1.8%). Mortality trend showed a non-significant decrease. Incidence and mortality rates from vaginal cancer were non-significantly decreased. For malignant neoplasm of cervix uteri, incidence rates showed a significant decrease by 2.1% per year. Mortality rates decreased as well, although non-significantly. HPV-related cancers consistently decreased in Umbria. This trend may be a consequence of safer sexual behavior. For cervical cancer, a combination of opportunistic and programmed screening led to a much-reduced disease burden. It is expected that the implementation of vaccination in the future will lead to a further decrease of HPV-related cancer incidence and mortality.

RESUMO

BACKGROUND: Patient satisfaction is a central topic in quality management in outpatient dental care. The ZAP questionnaire was validated to explore patient satisfaction in general and specialist outpatient settings. This study aims at assessing the psychometric properties of the ZAP in dental care. METHODS: A minimally modified version of the ZAP consisting of 4 domains (office organisation, cooperation, interaction, information) was administered in personal interviews to a population-based sample. Descriptive, exploratory and confirmatory psychometric analyses were conducted with random subsets of the study sample. RESULTS: The study population comprised 1 773 subjects with at least one dental visit during their lifetime (mean age=50 years, female=51.6%). The exploratory factor analysis identified 3 subscales (office organisation, interaction, information). Based on these results, items of the subscale "cooperation" were excluded from further analyses. The remaining items had a medium difficulty of 0.75, all item-total-correlations were above 0.4. Missing values ranged between 2.3% and 28.7%. Cronbach's alpha ranged between 0.79 and 0.95. After introduction of 3 residual correlations, the confirmatory factor analyses reached a good model fit (TLI: 0.97; CFI: 0.97, RMSEA: 0.06). Partial standardised factor loadings ranged between 0.77 and 0.87. The 3 latent factors were highly correlated. There was a positive correlation between the 3 subscales and global patient satisfaction with the dentist. CONCLUSION: The psychometric assessment can be used in the 3 modified subscales (office organisation, interaction, and information) to assess patient satisfaction with dental care. To assess dentist's competence in relation to dental anxiety and pain as well as shared decision making new scales specific to dental care should be explored.

RESUMO

INTRODUCTION: Dynamic Contrast-Enhanced Magnetic Resonance Mammography (DCE-MRM) represents the most sensitive examination for breast cancer (BC) diagnosis. However literature data reports very inhomogeneous specificity. The aim of our study was to evaluate the clinical efficiency of a new MRM technique - diffusion weighted imaging with background body signal suppression T2 image fusion in BC diagnosis, compared to DCE-MRM. METHODS: We retrospectively analyzed 50 consecutive DCE-MRM examinations with DWIBS sequence from the archives of the Department of Radiology, Lyon Sud Hospital, (02.2010- 02.2011), summing up to 64 breast lesions. Fusions were created using the Osirix software from the DWIBS images (b=1000 s mm2) and their T2 correspondents. Interpretation was performed using an adapted BI-RADS system. The final histopathological examination or a minimum 6-months follow-up served as gold standard. RESULTS: Out of the 64 examined breast lesions, 35(54.7%) were classified as malignant by DCE-MRM and 24(37.5%) cases by DWIBS T2, respectively. Thus the DWIBS T2 fusion had a Sensitivity of 62.5%(95%CI:35.4-84.8) and a Specificity of 70.8%(95%CI:55.9-83.3) while DCE-MRM had a higher Sensitivity: 87.5%(95%CI:61.6-98.4) but a lower Specificity: 56.2%(95%CI:41.1-70.5). CONCLUSION: DWIBS T2 fusion is an innovative MRM technique, with a specificity superior to DCE-MRM, showing a large potential for improving the clinical efficiency of classical MRM.

RESUMO

AIM: The present study aimed at investigating the effect of a 3-week training on biomarkers in professional soccer players during the preseason preparation-period. METHODS: Eight participants (age 22.5±2.2 yrs) were enrolled in the study. During the physical preparation period players have attended a training program (51.9 hours) formulated by coaches of "Equipe-Sicilia-2009". RESULTS: At rest, the lipid profile, the creatine kinase (CK), the lactic-acid dehydrogenase (LDH) and the expression of nuclear receptors peroxisome-proliferator-activated receptors (PPAR α/γ) were analyzed before starting and after 3 weeks of training. The plasma level of CK in our samples showed great variability already in the baseline: value was on average nearly 500 IU/l showed that a large amount of these athletes were a high responders. This biomarker showed a reduction (P<0.01) after 3 weeks of training. No modifications were found in the LDH plasma level, in the lipid profile and in the expression of mRNA of PPAR α/γ and also no significant person's correlations were found among variables. CONCLUSION: In conclusion, we retain that those basal biomarkers, except CK, are not able to assist coaches to better understand training adaptations and overreaching mechanisms during a 3-week of preseason preparation-period. More studies are necessary to confirm these results.

RESUMO

The SFE-AFCE-SFMN 2022 consensus deals with the management of thyroid nodules, a condition that is a frequent reason for consultation in endocrinology. In more than 90% of cases, patients are euthyroid, with benign non-progressive nodules that do not warrant specific treatment. The clinician's objective is to detect malignant thyroid nodules at risk of recurrence and death, toxic nodules responsible for hyperthyroidism or compressive nodules warranting treatment. The diagnosis and treatment of thyroid nodules requires close collaboration between endocrinologists, nuclear medicine physicians and surgeons, but also involves other specialists. Therefore, this consensus statement was established jointly by 3 societies: the French Society of Endocrinology (SFE), French Association of Endocrine Surgery (AFCE) and French Society of Nuclear Medicine (SFMN); the various working groups included experts from other specialties (pathologists, radiologists, pediatricians, biologists, etc.). This section deals with the technique and interpretation of thyroid fine-needle aspiration biopsy (FNAB), a reference test for the analysis of thyroid nodules.
