Abstract
Aim The short-term and long-term efficacy of different thermal percutaneous ablation techniques remains a topical issue. Our group implemented percutaneous laser ablation (LA), a moving-shot technique to increase efficiency and reduce costs and variability of LA by applying multiple lower-intensity energy illuminations (MLIEI) covering the nodular volume (V) through changes in position of a single laser fiber within the thyroid nodule. The aim of the present study was to evaluate the efficacy of the single-fiber LA-MLIEI during a 5-year follow-up and to identify possible predictors of the final outcome. Methods Prospective study: Thirty outpatients (23 women and seven men) with benign symptomatic thyroid nodules were assigned to single-fiber LA-MLIEI, between 2012 and 2015. A single LA session was performed under real-time ultrasound (US) guidance using a 1,064-nm continuous-wave laser at 3 W. A 400-µm optical fiber was inserted through a 21-gauge needle, and 3–10 illuminations were performed per nodule, administering between 400 and 850 J/illumination. The total administered energy was calculated on the initial V of the nodule and the estimated ablation area. US evaluation was performed after LA-MLIEI at 1 week and 1, 3, 6, and 12 months and after that annually up to 5 years. Clinical symptoms, laboratory thyroid function during follow-up, and acute and chronic complications of treatment were registered. Results On follow-up, 67% (n: 20) were responders to single-fiber LA-MLIEI, while 33% (n: 10) were non-responders. The responder group initiated V reduction (ΔV) at 1 month, with remission of symptoms, and presented a 50% ΔV at 3 months of treatment; the maximum response was achieved at 24 months and remained stable until the end of the study. The non-responder group presented a ΔV of less than 50% at 12 months; though a tendency to >50% ΔV was observed at 24–36 months, there was subsequent regrowth, and 40% of this group required surgery. ΔV was positively correlated with the total administered energy/V (J/V) and inversely with nodule V. No severe adverse effects were observed. Thyroid function remained normal in all patients. Remission of symptoms occurred rapidly after 1 month. Conclusions LA with multiple fractional discharges employing a single fiber in a unique session is a safe and inexpensive technique that allows rapid reduction of thyroid nodules, with a stable response up to 5 years, similarly to what has been reported with the conventional LA. Total nodule volume appears as a predictive factor of the reduction.

Abstract
We present the LUCA device, a multi-modal platform combining eight-wavelength near infrared time resolved spectroscopy, sixteen-channel diffuse correlation spectroscopy and a clinical ultrasound in a single device. By simultaneously measuring the tissue hemodynamics and performing ultrasound imaging, this platform aims to tackle the low specificity and sensitivity of the current thyroid cancer diagnosis techniques, improving the screening of thyroid nodules. Here, we show a detailed description of the device, components and modules. Furthermore, we show the device tests performed through well established protocols for phantom validation, and the performance assessment for in vivo. The characterization tests demonstrate that LUCA device is capable of performing high quality measurements, with a precision in determining in vivo tissue optical and dynamic properties of better than 3%, and a reproducibility of better than 10% after ultrasound-guided probe repositioning, even with low photon count-rates, making it suitable for a wide variety of clinical applications.

Abstract
Chronic cortisol excess induces several alterations on protein, lipid and carbohydrate metabolism resembling those found in the metabolic syndrome. However, patients exposed to prolonged high levels of cortisol in Cushing syndrome (CS) present exceeding cardiometabolic alterations not reflected by conventional biomarkers. Using 3 ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS) platforms, we aimed to characterise the serum metabolome of 25 patients with active endogenous CS and 25 control subjects matched by propensity score (sex, BMI, diabetes mellitus type 2 (T2D), high blood pressure (HBP) and dyslipidaemia) to search for potential disease-specific biomarkers and pathways associated to the clinical comorbidities. A total of 93 metabolites were significantly altered in patients with CS. Increased levels of sulfur amino acids (AA), triacylglycerols, glycerophospholipids, ceramides and cholesteryl esters were observed. Contrarily, concentrations of essential and non-essential AA, polyunsaturated fatty acids, conjugated bile acids and second messenger glycerolipids were decreased. Twenty-four-hour urinary free cortisol (24h-UFC) independently determined the concentration of 21 lipids and 4 AA. A metabolic signature composed by 10 AA and 10 lipid metabolites presented an AUC-ROC of 95% for the classification of CS patients. Through differential network analysis, 152 aberrant associations between metabolites involved in the Lands cycle and Kennedy pathway were identified. Our data indicates that chronic hypercortisolemia confers a unique lipidomic signature and several alterations in numerous AA even when compared to patients with similar metabolic comorbidities providing novel insights of the increased cardiometabolic burden of CS. KEY MESSAGES: • Cortisol excess induces metabolic alterations beyond conventional biomarkers. • The hypercortisolism extent determines the concentration of 21 lipids and 5 aa. • Cortisol excess confers a unique metabolic signature of 20 metabolites. • Kennedy and Lands cycle are profoundly disturbed by cortisol excess.

Abstract
Transgender men and women represent about 0.6 -1.1%% of the general population. Gender affirming hormone therapy (GAHT) helps ameliorate gender dysphoria and promote well-being. However, these treatments' cardiovascular (CV) effects are difficult to evaluate due to the limited number of extensive longitudinal studies focused on CV outcomes in this population. Furthermore, these studies are mainly observational and difficult to interpret due to a variety of hormone regimens and observation periods, together with possible bias by confounding factors (comorbidities, estrogen types, smoking, alcohol abuse, HIV infection). In addition, the introduction of GAHT at increasingly earlier ages, even before the full development of the secondary sexual characteristics, could lead to long-term changes in CV risk compared to current data. This review examines the impact of GAHT in the transgender population on CV outcomes and surrogate markers of CV health. Furthermore, we review available data on changes in DNA methylation or RNA transcription induced by GAHT that may translate into changes in metabolic parameters that could increase CV risk.

Abstract
OBJECTIVE Abdominal fat ultrasound (US) is a simple clinical tool that may allow measures of fat depots not visible using common dual-energy X-ray absorptiometry (DEXA) or computerized tomography (CT) imaging. The aim of this study was to validate the technique, give measures of superficial and profound subcutaneous, preperitoneal, omental and perirenal (retroperitoneal) fat and correlate them with MS markers. METHODS Sequential US measures of these five abdominal fat layers were done at 397 adults. Blood pressure (BP), body mass index (BMI), waist, body fat %, HOMA-IR index (homeostatic model assessment of insulin resistance), lipid profile and leptin were recorded. Metabolic syndrome (MS) was defined according to Cholesterol education programme adult treatment panel III (ATPIII) criteria. RESULTS Subcutaneous and omental fat were increased among people with obesity, whereas preperitoneal and perirenal fat did not show any difference according to BMI or waist. Women showed thicker subcutaneous fat (both superficial and profound), whereas men had bigger omental fat. Both postmenopausal and diabetic patients had changes in omental fat only, whereas patients with fatty liver showed thicker preperitoneal and perirenal fat, as well. MS patients showed both thicker perirenal and omental fat. A cut-off of 54 mm in male (M)/34 mm in female (F) of omental fat and 22.5 mm (M)/12.5 mm (F) of perirenal fat could be predictive of later MS onset. CONCLUSIONS US is a valid method to measure all different abdominal fat depots. Omental and perirenal fat measures may classify patients at risk for MS. Preperitoneal fat depot may also correlate with fatty liver disease.

Abstract
BACKGROUND Brain sexual differentiation is a process that results from the effects of sex steroids on the developing brain. Evidence shows that epigenetics plays a main role in the formation of enduring brain sex differences and that the estrogen receptor α (ESR1) is one of the implicated genes. AIM To analyze whether the methylation of region III (RIII) of the ESR1 promoter is involved in the biological basis of gender dysphoria. METHODS We carried out a prospective study of the CpG methylation profile of RIII (-1,188 to -790 bp) of the ESR1 promoter using bisulfite genomic sequencing in a cisgender population (10 men and 10 women) and in a transgender population (10 trans men and 10 trans women), before and after 6 months of gender-affirming hormone treatment. Cisgender and transgender populations were matched by geographical origin, age, and sex. DNAs were treated with bisulfite, amplified, cloned, and sequenced. At least 10 clones per individual from independent polymerase chain reactions were sequenced. The analysis of 671 bisulfite sequences was carried out with the QUMA (QUantification tool for Methylation Analysis) program. OUTCOMES The main outcome of this study was RIII analysis using bisulfite genomic sequencing. RESULTS We found sex differences in RIII methylation profiles in cisgender and transgender populations. Cismen showed a higher methylation degree than ciswomen at CpG sites 297, 306, 509, and at the total fragment (P ≤ .003, P ≤ .026, P ≤ .001, P ≤ .006). Transmen showed a lower methylation level than trans women at sites 306, 372, and at the total fragment (P ≤ .0001, P ≤ .018, P ≤ .0107). Before the hormone treatment, transmen showed the lowest methylation level with respect to cisgender and transgender populations, whereas transwomen reached an intermediate methylation level between both the cisgender groups. After the hormone treatment, transmen showed a statistically significant methylation increase, whereas transwomen showed a non-significant methylation decrease. After the hormone treatment, the RIII methylation differences between transmen and transwomen disappeared, and both transgender groups reached an intermediate methylation level between both the cisgender groups. CLINICAL IMPLICATIONS Clinical implications in the hormonal treatment of trans people. STRENGTHS & LIMITATIONS Increasing the number of regions analyzed in the ESR1 promoter and increasing the number of tissues analyzed would provide a better understanding of the variation in the methylation pattern. CONCLUSIONS Our data showed sex differences in RIII methylation patterns in cisgender and transgender populations before the hormone treatment. Furthermore, before the hormone treatment, transwomen and transmen showed a characteristic methylation profile, different from both the cisgender groups. But the hormonal treatment modified RIII methylation in trans populations, which are now more similar to their gender. Therefore, our results suggest that the methylation of RIII could be involved in gender dysphoria. Fernández R, Ramírez K, Gómez-Gil E, et al.

Abstract
Abstract
Background: Alterations in circulating amino acids, polyamines and acylcarnitines have been reported in patients with endogenous chronic hypercortisolism. However, lipid metabolites profiling and its interplay with the serum metabolome and degree of hypercortisolism in patients with active Cushing syndrome (CS) has not been previously assessed. Objective: To identify new metabolomic biomarkers associated with active CS.
Methodology: Multiple UHPLC-MS platforms were used to analyze the metabolome of serum samples obtained from 25 patients with active endogenous CS and 25 controls subjects matched by propensity score (sex, BMI, T2D, DLP, HBP).
Results: Metabolome of CS patients was deeply disrupted with 122 (27%) of the assessed metabolites significantly altered (p adj. <0.05) out of which 5 bile acids resulted with the highest perturbation (> 2-fold decrease). From the altered metabolites, 3 amino acids (AA), 2 acylcarnitines (ACs), 2 ceramides (CER) and 5 glycerophospholipids showed direction of effect independently associated with 24-h urinary free cortisol (MS) levels. A highly discriminant (AUC 96%) metabolome signature (n=59) characterized by lower levels of AA, ACs, polyunsaturated fatty acids (PUFA) and monoglycerophosphocolines (MGPC) together with increased levels of triacyclglycerols (TG), CER, diacylglycerophosphocholines (DGPC) and cholesteryl esters was identified and cross-validated (R2Y= 0.92, Q2Y= 0.68) using PLS-DA VIP scores >1.5. PUFA omega-6, and alanine, aspartate and glutamate metabolism resulted the most impacted canonical pathways (q-stat 19.7, 10.8 (p<0.001). Finally, topological network analysis detected 158 pairwise differential correlations (p <0.005, 10,000-fold permutation) between 141 metabolites due to CS where the acylPC (P-18:1/0:0) resulted a key metabolite in the network (betweenness =0.117 & closeness centrality =0.467).
Conclusion: Active Cushing syndrome leads to a global proatherogenic shift in the circulating ceramides, glycerophospholipids and sphingolipids metabolites which are independently associated to the levels of urinary free cortisol being potential biomarkers of patients’ cardiovascular risk.

Abstract
BACKGROUND The effectiveness of mindfulness and self-compassion-based interventions (MSCI) on emotional fatigue and stress in Primary Healthcare (PHC) professionals has been demonstrated in the short term. The aims of this work were to assess whether these effects persist after two years, and if the observed results differ between those who practiced mindfulness regularly during the follow-up (meditators) and those who did not. METHODS Prospective study - pre-post and two years after performing an MSCI that was offered to all PHC professionals in Navarra, with group sessions of 2.5 hours / week for 8 weeks. Attending at least 75% of the sessions and practicing at home for 45 minutes a day were mandatory. At the three moments of the study, questionnaires were distributed to measure levels of mindfulness (FFMQ), self-compassion (SCS), perceived stress (PSQ) and burnout (MBI). At the end of the follow-up period, participants were asked if they were meditators and the time they dedicated to this weekly. RESULTS Forty-eight professionals were enrolled and 41 (83% women) met the inclusion criteria, without loss to follow-up. Mean scores in mindfulness, self-compassion and perceived stress significantly improved after the intervention and in the long term (p <0.001), without observing differences in the level of burnout. The group of meditators achieved a greater long-term improvement in self-compassion (3.6 points vs. 1.6). CONCLUSIONS The effectiveness of an MSCI persists two years later regardless of meditator status, although there is a significant improvement in self-compassion in the meditators.

Abstract
Recently, multimodal imaging has gained an increasing interest in medical applications thanks to the inherent combination of strengths of the different techniques. For example, diffuse optics is used to probe both the composition and the microstructure of highly diffusive media down to a depth of few centimeters, but its spatial resolution is intrinsically low. On the other hand, ultrasound imaging exhibits the higher spatial resolution of morphological imaging, but without providing solid constitutional information. Thus, the combination of diffuse optical imaging and ultrasound may improve the effectiveness of medical examinations, e.g. for screening or diagnosis of tumors. However, the presence of an ultrasound coupling gel between probe and tissue can impair diffuse optical measurements like diffuse optical spectroscopy and diffuse correlation spectroscopy, since it may provide a direct path for photons between source and detector. A systematic study on the effect of different ultrasound coupling fluids was performed on tissue-mimicking phantoms, confirming that a water-clear gel can produce detrimental effects on optical measurements when recovering absorption/reduced scattering coefficients from time-domain spectroscopy acquisitions as well as particle Brownian diffusion coefficient from diffuse correlation spectroscopy ones. On the other hand, we show the suitability for optical measurements of other types of diffusive fluids, also compatible with ultrasound imaging.

Abstract
PURPOSE Gender affirming hormone therapy (HT) in transgender men both improves and impairs several surrogate cardiovascular risk markers. However, few prospective works with long follow-up and control group are available. In this context, this work aimed to assess the changes in the metabolic and cardiovascular risk pattern after 12 months of HT in transgender men. Furthermore, we aimed to investigate early effects on target tissues that may reflect an initial vascular damage. METHODS Prospective observational study, including 20 transgender men, attended in the Gender Identity Unit (UIG) of the Hospital Clinic from July 2013 to November 2015. Anthropometric and body composition by dual-energy X-ray absorptiometry (DXA), hormonal, metabolic and coagulation parameters, endothelial dysfunction by flow-mediated dilation (FMD) and intima-media thickness (IMT) by carotid ultrasound, were assessed at baseline, at 6 and 12 months of HT. RESULTS We observed an impairment of lipid profile, and increase of homocysteine and leucocytes count, as well as changes in body composition with increased total lean mass together with decreased total fat mass. In addition, higher mean-maximum common IMT was observed after 12 months of HT. CONCLUSION Our work shows changes in metabolic and inflammatory parameters after HT after short-medium follow-up, which could increase cardiovascular risk in this setting, together with initial evidence of vascular changes.

Abstract
BACKGROUND Polymorphisms in sex steroid receptors have been associated with transsexualism. However, published replication studies have yielded inconsistent findings, possibly because of a limited sample size and/or the heterogeneity of the transsexual population with respect to the onset of dysphoria and sexual orientation. We assessed the role of androgen receptor (AR), estrogen receptors alpha (ERα) and beta (ERβ), and aromatase (CYP19A1) in two large and homogeneous transsexual male-to-female (MtF) and female-to-male (FtM) populations. METHODS The association of each polymorphism with transsexualism was studied with a twofold subject-control analysis: in a homogeneous population of 549 early onset androphilic MtF transsexuals versus 728 male controls, and 425 gynephilic FtMs versus 599 female controls. Associations and interactions were investigated using binary logistic regression. RESULTS Our data show that specific allele and genotype combinations of ERβ, ERα and AR are implicated in the genetic basis of transsexualism, and that MtF gender development requires AR, which must be accompanied by ERβ. An inverse allele interaction between ERβ and AR is characteristic of the MtF population: when either of these polymorphisms is short, the other is long. ERβ and ERα are also associated with transsexualism in the FtM population although there was no interaction between the polymorphisms. Our data show that ERβ plays a key role in the typical brain differentiation of humans. CONCLUSION ERβ plays a key role in human gender differentiation in males and females.

Abstract
Thyroid plays an important role in the endocrine system of the human body. Its characterization by diffuse optics can open new path ways in the non-invasive diagnosis of thyroid pathologies. Yet, the absorption spectra of tyrosine and thyroglobulin–key tissue constituents specific to the thyroid organ–in the visible to near infrared range are not fully available. Here, we present the optical characterization of tyrosine (powder), thyroglobulin (granular form) and iodine (aqueous solution) using a time domain broadband diffuse optical spectrometer in the 550–1350 nm range. Various systematic errors caused by physics of photo migration and sample inherent properties were effectively suppressed by means of advanced time domain diffuse optical methods. A brief comparison with various other known tissue constituents is presented, which reveals key spectral regions for the quantification of the thyroid absorbers in an in vivo scenario.

Abstract
OBJECTIVE Sustained evidence from observational studies indicates that after remission of Cushing syndrome (CS) a cardiovascular risk phenotype persists. Here, we performed a translational study in active CS and CS in remission (RCS) to evaluate the subclinical cardiometabolic burden and to explore the direct pro-inflammatory and prothrombotic potential of their sera on the endothelium in an in vitro translational atherothrombotic cell model. PATIENTS Cross sectional study. The groups were (n = 9/group): I. RCS; II. Active CS (ACS) and III. Controls (CTR), all matched for age, body mass index, sex, without other hormonal deficits. DESIGN We evaluated in vivo: cardiometabolic profile; endothelial markers (sVCAM-1, NO); endothelial dysfunction (FMD); intima-media thickness and body composition (DEXA). In vitro endothelial cells (EC) were exposed to sera taken from the different subjects to evaluate inflammatory EC response (tisVCAM) and thrombogenicity of the generated extracellular matrix (ECM): von Willebrand factor (VWF) and platelet reactivity. RESULTS Three of the 9 RCS subjects were on glucocorticoid replacement therapy (GC-RT). Patients on GC-RT had a shorter period of time in stable remission. In vivo analysis ACS showed typically metabolic features, while cardiometabolic markers reached statistical significance for RCS only for Hs-CRP (P < .01). In vitro:EC exposed to ACS and RCS sera displayed increased tisVCAM-1 (P < .01 for ACS and P < .05 for RCS vs CTR), VWF (P < .01 for ACS and P < .05 for RCS vs CTR) and platelet adhesion on ECM (P < .01 for ACC and P < .05 for RCS vs CTR). No statistically significant differences were observed between GC-RT RSC and RCS without GC-RT. CONCLUSIONS The sera of premenopausal women with CS in remission, without atherothrombotic disease, contain circulatory endothelial deleterious factors with a direct thrombogenic and pro-inflammatory endothelial effect that could increase cardiovascular risk.

Abstract
Cross-sex hormone therapy (CHT) is critical for phenotypical and physiological transition in adults with gender dysphoria (GD). However, the impact of the CHT onto the molecular level/epigenetic regulation has not been comprehensively addressed. We postulate that CHT in GD could drive changes at the androgen receptor (AR), estrogen receptor alpha (ESR1) and estrogen receptor beta (ESR2), affecting their DNA methylation pattern and mRNA expression that may influence in the phenotypical changes associated to CHT. We carried out a prospective observational study on individuals with a diagnosis of GD. 18 subjects (no previous CHT): 12 female to male (FtoM) and 6 male to female (MtoF). An Epityper Mass array TM method was used to study the DNA methylation and Real-time PCR quantitative reverse transcription PCR (qRT-PCR) was used to quantify the gene expression. The analysis of AR, ESR1 and ESR2 receptor was performed at baseline, 6 and 12 months after CHT. No differences in DNA methylation of ESR were found in MtoF, while DNA methylation was increased in FtoM at 6 and 12 months of CHT. The AR showed a significant increase of methylation in MtoF group after 12 months of estrogenic treatment. Regarding the expression analysis, AR expression was significantly decreased in FtoM upon CHT treatment. AR, ESR1 and ESR2 methylation were correlated with anthropometric, metabolic and hormonal parameters in FtoM and MtoF. Our results support that CHT is associated to epigenetic changes that might affect the response to treatment with sex steroids.

Abstract
Glucocorticoids (GC) induce cardiometabolic risk while atherosclerosis is a chronic inflammation involving immunity. GC are immune suppressors, and the adrenocorticotrophic hormone (ACTH) has immune modulator activities. Both may act in atherothrombotic inflammation involving immune cells (IMNC). Aim. To investigate adhesion and activation surface cell markers (CDs) of peripheral IMNC in endogenous Cushing syndrome (CS) and the immune modulator role of ACTH. Material and Methods. 16 ACTH-dependent CS (ACTH-D), 10 ACTH-independent (ACTH-ID) CS, and 16 healthy controls (C) were included. Leukocytes (Leuc), monocytes (MN), lymphocytes (Lym), and neutrophils (N) were analyzed by flow cytometry for atherosclerosis previously associated with CDs. Results. Leuc, N, and MN correlated with CS (p < 0.05), WC (p < 0.001), WHR (p = 0.003), BMI (p < 0.001), and hs-CRP (p < 0.001). CD14++CD16+ (p = 0.047); CD14+CD16++ (p = 0.053) MN; CD15+ (p = 0.027); CD15+CD16+ (p = 0.008) N; and NK-Lym (p = 0.019) were higher in CS. CD14+CD16++ MN were higher in ACTH-ID (8.9 ± 3.5%) versus ACTH-D CS (4.2 ± 1.9%) versus C (4.9 ± 2.3%). NK-Lym correlated with c-LDL (r = 0.433, p = 0.039) and CD15+ N with hs-CRP (r = 0.446, p = 0.037). In multivariate analysis, Leuc, N, and MN depended on BMI (p = 0.021), WC (p = 0.002), and WHR (p = 0.014), while CD15+ and CD15+CD16+ N on hypercortisolism and CS (p = 0.035). Conclusion. In CS, IMNC present changes in activation and adhesion CDs implicated in atherothrombotic inflammation. ACTH-IDCS presents a particular IMNC phenotype, possibly due to the absence of the immune modulator effect of ACTH.

Abstract
PURPOSE Urinary free cortisol (UFC) determination by highly specific methods as mass spectrometry instead of commercially available antibody-based immunoassays is increasingly recommended. However, clinical comparisons of both analytical approaches in the screening of Cushing's syndrome (CS) are not available. The aim of this study was to evaluate the diagnostic value of mass spectrometry versus immunoassay measurements of 24 h-UFC in the screening of CS. METHODS Cross-sectional study of 33 histologically confirmed CS patients: 25 Cushing's disease, 5 adrenal CS and 3 ectopic CS; 92 non-CS patients; and 35 healthy controls. UFC by immunoassay (UFCxIA) and mass spectrometry (UFCxMS), urinary free cortisone (UFCo) and UFC:UFCo ratio were measured, together with creatinine-corrected values. Sensitivity, specificity, AUC and Landis and Koch concordance index were determined. RESULTS AUC for UFCxIA and UFCxMS were 0.77 (CI 0.68-0.87) and 0.77 (CI 0.67-0.87) respectively, with a kappa coefficient 0.60 and strong Landis and Koch concordance index. The best calculated cutoff values were 359 nmol/24 h for UFCxIA (78 % sensitivity, 62 % specificity) and 258.1 nmol/24 h for UCFxMS (53 % sensitivity, 86 % specificity). The upper limit of UFCxIA and UCFxMS reference ranges were 344.7 and 169.5 nmol/24 h respectively. Sensitivity and specificity for CS diagnosis at these cutpoints were 84 and 56 % for UFCxIA and 81 and 54 % for UFCxMS. CONCLUSIONS According to our data, both methods present a very similar diagnostic value. However, results suggest that lower cutoff points for mass spectrometry may be necessary in order to improve clinical sensitivity.

Abstract
BACKGROUND Nutrition therapy is the cornerstone of treating diabetes mellitus. The inclusion of fish (particularly oily fish) at least two times per week is recommended by current international dietary guidelines for type 2 diabetes. In contrast to a large number of human studies examining the effects of oily fish on different cardiovascular risk factors, little research on this topic is available in patients with type 2 diabetes. The aims of this pilot study were to investigate the effects of a sardine-enriched diet on metabolic control, adiponectin, inflammatory markers, erythrocyte membrane fatty acid (EMFA) composition, and gut microbiota in drug-naïve patients with type 2 diabetes. METHODS 35 drug-naïve patients with type 2 diabetes were randomized to follow either a type 2 diabetes standard diet (control group: CG), or a standard diet enriched with 100 g of sardines 5 days a week (sardine group: SG) for 6 months. Anthropometric, dietary information, fasting glycated hemoglobin, glucose, insulin, adiponectin, inflammatory markers, EMFA and specific bacterial strains were determined before and after intervention. RESULTS There were no significant differences in glycemic control between groups at the end of the study. Both groups decreased plasma insulin (SG: -35.3%, P = 0.01, CG: -22.6%, P = 0.02) and homeostasis model of assessment--insulin resistance (HOMA-IR) (SG: -39.2%, P = 0.007, CG: -21.8%, P = 0.04) at 6-months from baseline. However only SG increased adiponectin in plasma compared to baseline level (+40.7%, P = 0.04). The omega-3 index increased 2.6% in the SG compared to 0.6% in the CG (P = 0.001). Both dietary interventions decreased phylum Firmicutes (SG and CG: P = 0.04) and increased E. coli concentrations (SG: P = 0.01, CG: P = 0.03) at the end of the study from baseline, whereas SG decreased Firmicutes/Bacteroidetes ratio (P = 0.04) and increased Bacteroides-Prevotella (P = 0.004) compared to baseline. CONCLUSIONS Although enriching diet with 100 g of sardines 5 days a week during 6 months to a type 2 diabetes standard diet seems to have neutral effects on glycemic control in drug-naïve patients with type 2 diabetes, this nutritional intervention could have beneficial effects on cardiovascular risk. Furthermore, both dietary interventions decreased HOMA-IR and altered gut microbiota composition of drug-naïve patients with type 2 diabetes.

Abstract
OBJECTIVE Transsphenoidal surgery is the procedure of choice in Cushing disease (CD), with immediate post-operative remission rates ranging between 59 and 94% and recurrence rates between 3 and 46%, both depending upon the definition criteria and the duration of the follow-up. Our aim was to assess the rate of remission, recurrence and persistence of the disease after the first treatment and to identify predictors of remission in the CD population of our center. METHODS Retrospective cohort study of the patients diagnosed of CD and with follow-up in our center between 1974 and 2011. We analyzed 41 patients (35 women and 6 men) with a mean age at diagnosis of 34 ± 13 years. The mean follow-up was 14 ± 10 years (range 1-37 years) and the median of follow-up period was 6.68 years. RESULTS Thirty-five (85.4%) patients underwent transsphenoidal surgery as first treatment option. Histopathological evidence of a pituitary adenoma was registered in 17 (48.5%) patients. Thirty-two (78%) patients achieved disease remission after the first treatment, 21 (65.6%) of them presented disease recurrence. Persistent disease was observed in 9 (22%) patients. Twelve (29.3%) subjects developed post-surgical adrenal insufficiency, 7 of which (70%) achieved stable remission. Two parameters were found to be significant predictors of remission after the first treatment: age at disease diagnosis and the development of adrenal insufficiency (cortisol <3 μg/dl) in the immediate post-operative state. CONCLUSIONS We report a high recurrence rate, at least partially attributable to the long follow-up time. Early post-surgery adrenal insufficiency predicts remission. Hypopituitarism was also very prevalent, and strongly associated with radiotherapy. These results lead us to the conclusion that CD needs a life-long strict follow-up.

Abstract
Clock gene expression was associated with different components of metabolic syndrome (MS) in human adipose tissue. However, no study has been done to compare the expression of clock genes in visceral adipose tissue (VAT) from lean and obese subjects and its clinical implications. Therefore, we studied in lean and obese women the endogenous 24 h expression of clock genes in isolated adipocytes and its association with MS components. VAT was obtained from lean (BMI 21-25 kg/m2; n = 21) and morbidly obese women (BMI >40 kg/m2; n = 28). The 24 h pattern of clock genes was analyzed every 6 hours using RT-PCR. Correlation of clinical data was studied by Spearman analysis. The 24 h pattern of clock genes showed that obesity alters the expression of CLOCK, BMAL1, PER1, CRY2 and REV-ERB ALPHA in adipocytes with changes found in CRY2 and REV-ERB ALPHA throughout the 24 h period. The same results were confirmed in VAT and stromal cells (SC) showing an upregulation of CRY2 and REV-ERB ALPHA from obese women. A positive correlation was observed for REV-ERB ALPHA gene expression with BMI and waist circumference in the obese population. Expression of ROR ALPHA was correlated with HDL levels and CLOCK with LDL. Obese subjects with MS exhibited positive correlation in the PER2 gene with LDL cholesterol, whereas REV-ERB ALPHA was correlated with waist circumference. We identified CRY2 and REV-ERB ALPHA as the clock genes upregulated in obesity during the 24 h period and that REV-ERB ALPHA is an important gene associated with MS.

Abstract
The purpose of this study is to assess the potential relationships of circulating IGF-I, adrenal and gonadal steroids, and polymorphism ER22/23EK of the glucocorticoid receptor (GC-R) gene with nutritional, functional and cognitive deterioration in a group of elderly people living independently. This is a population-based prospective study with 313 individuals (160 women and 153 men, 76.7 ± 7 years) who participated. A physical exam, evaluation of functional capacity (Barthel scale), cognitive function (mini-mental state examination-MMSE), geriatric depression scale (GDS), mininutritional assessment (MNA-SF) and cardiometabolic status were performed at basal time point and at 2 years of follow-up. Biological measurements included cortisol, dehydroepiandrosterone (DHEA), DHEA sulphate, testosterone, estradiol, IGF-I and polymorphism ER22/23EK of the GC-R gene. Estradiol was associated with MNA-SF decrease over time (p < 0.01, adjusted for age and gender, beta = -0.17, p = 0.03). Weight loss was related to testosterone in men (8.6 vs 12.1 pg/ml in no losers; p = 0.03), and in women with GDS (13.0% with depression vs 3.3% with no depression; p = 0.05) and MMSE (22.2% with cognitive deterioration vs 4.8% with no cognitive deterioration; p = 0.049). Barthel decrease was associated with testosterone (p = 0.02, after adjusting for age and gender, beta = -0.520, p < 0.001), and SHBG (p < 0.01, adjusted for age and gender, beta = 0.18, p < 0.01). DHEA was associated with deterioration in the MMSE (p = 0.01, after adjusting for age, gender, GDS scale and academic status, beta = -0.26, p = 0.01). Frailty development was related only in men with testosterone levels at the beginning of the study (p = 0.017). ER22/23EK was found in 3% of the subjects and carriers had a lower prevalence of hypertension. Adrenal and gonadal steroids are associated to impairment of the ageing health condition in elderly individuals living independently in Spain. ER22/23EK polymorphism of the GC-R gene has a low prevalence in our population.

Abstract
The numbers of different types of ovarian follicles (developing, degenerating and postovulatory follicles) were estimated in bluefin tuna Thunnus thynnus using two stereological procedures: the model-based method of Weibel & Gomez, which has become a tool of broad application in the quantification of oocytes in fishes, and the assumption-free 'disector' (sic) method of Sterio. The estimates of developing follicles (follicles containing lipid-stage, vitellogenic and migratory-nucleus oocytes) made by the model-based method tended to be lower than those obtained with the disector, though significant differences were not observed except for vitellogenic follicles. Counts of atretic follicles by the model-based method were higher than those made using the disector, the differences being remarkable between both techniques, particularly in the case of beta-atresia, where the statistical analysis indicated significantly unequal estimations with the two methods. In contrast, the amount of postovulatory follicles estimated by the disector, which would stand for the realized batch fecundity, was somewhat larger than that calculated with the model-based method.

Abstract
Subcellular mRNA localization, a fundamental mechanism for regulating gene expression, leads to local protein translation that results in the generation of neuronal cell polarity. In this study, we have used P19 embryonic carcinoma cells, which are amenable to transfection, and selection of clonal stable cell lines that are not overexpressing the constructs. We identified the 3' untranslated region (3'UTR) tau axonal localization signal and examined its effect on tau protein localization in nondifferentiated and neuronally differentiated P19 cells. Using GFP-tagged tau constructs combined with in situ hybridization analysis, we demonstrated colocalization of the targeted tau mRNA and its translated protein in the axon and growth cone. Absence of or mutation in the 3'UTR axonal targeting region of tau mRNA resulted in suppression of tau mRNA localization, and both tau mRNA and tau protein remained in the cell body. Swapping between the 3'UTR tau mRNA axonal localization signal and the 3'UTR MAP2 mRNA dendritic targeting signal proved that the localization of the proteins into the axon or dendrites depends on the specific 3'UTR targeting signals. Moreover, the identification of ribosomal proteins in the axon lends further support to the presence of protein synthetic machinery in the axons, a prerequisite for local translation. It is suggested therefore that the P19 cell system can be used to analyze mutations that affect mRNA transport and local translation and that it has the potential of being used to examine the onset of the neuronal differentiation process.

Abstract
Incubation of confertifolin and isodrimenin with Mucor plumbeus, Aspergillus niger or Rhizopus arrhizus gave in good yields the corresponding 3 beta-hydroxy derivatives. From isodrimenin, the known natural 7 alpha-hydroxy derivative (futronolide) was also obtained and its structure was definitely established by X-ray crystallographic study of its acetate derivative.

Abstract
The expression of dystrophin-protein 71 (Dp71) was investigated during nerve growth factor (NGF) induced differentiation of PC12 cells. A semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) assay was designed to measure Dp71 mRNA, whereas the Dp71 protein amount was evaluated by immunoblot analysis using an anti-dystrophin monoclonal antibody. Comparison with control cultures showed that Dp71 mRNA and protein levels increased in parallel with NGF treatment peaking with increments of 60% and 1.4 times, respectively. The upregulation of Dp71 expression during PC12 cells differentiation point at PC12 cells as a suitable model for studying the function of Dp71 in neuronal cells.

Abstract
In the past, if infection was present at the time a spinal dermal sinus was discovered, the sinus opening and cerebrospinal fluid were sterilized with a course of appropriate antibiotic therapy prior to the surgical intervention. The cases of two children with an infected spinal dermal sinus are reported here. One patient developed acute paraplegia during the initial stage of antibiotic therapy, and the second patient, who was admitted only with signs of fever and irritability, experienced after antibiotic therapy a complete myelographic blockade secondary to a large infected intradural dermoid tumor. The authors stress the importance of early neuroradiological and neurosurgical management of these lesions, even when an infection is present.

Abstract
Regioselective oxidation of methyl beta-muricholate to give the 6-ketoderivative is described. Stereoselective reduction of this ketone with tritiated NaBH4 furnishes labeled methyl beta-muricholate. The structure of all compounds was confirmed by infrared, 1H, and 13C nuclear magnetic resonance spectroscopy. Data obtained by circular dichroism and mass spectroscopy were in agreement with the structure of the ketone 3.

Abstract
A case of an post-traumatic arteriovenous fistula of the right temporal superficial artery in a diabetic child is reported. In absent of a cranial fracture, the lesion was notorious for the first time, ten months after a simple head injury. The progressive increase in size and the beginning of a frequent parietal right headache were the initial symptoms and important signs. The malformation was clipped on both sides and removed completely. The diagnosis and treatment are discussed as well as the theory on the pathogenesis of the lesion.

Abstract
A naphthaleneacetic acid tolerant mutant isolated from a mutagenized culture of tobacco mesophyll protoplasts and impaired in root morphogenesis has been previously characterized by genetic analysis. To understand the biochemical basis for naphthaleneacetic acid resistance, cells derived from this mutant and from wild-type tobacco were compared for their ability to respond to various growth regulators. The growth promoting abilities and cytotoxicities of auxin analogs were different for mutant and wild-type cells. These different activities were not correlated with increased rate of conjugation or breakdown of the auxins by mutant cells. These observations, as well as previous studies on the interaction of the mutant with Agrobacterium, suggest that mutant resistance to auxins is not a result of a specific modification of the process by which auxins induce cell killing, but to a more general alteration of the cellular response to auxin. A screening of auxin-related molecules which induce cell death in wild-type cells but not mutant cells without promoting growth in either was performed. p-Bromophenyleacetic acid was found to display these characteristics.

Abstract
Auxin induction of the proliferation of Nicotiana tabacum (cv Xanthi) mesophyll protoplasts and of protoplast-derived cells was studied. The growth-promoting properties and cytotoxicities at high concentrations of IAA and naphthaleneacetic acid were strongly affected by cell density. The induction of growth by 2,4-dichlorophenoxyacetic acid and picloram was not affected by cell density. The comparison of catabolism of these [(14)C]-labeled auxins by protoplasts showed that IAA and naphthalene-acetic acid were rapidly accumulated and conjugated unlike 2,4-dichlorophenoxyacetic acid and picloram. The major catabolite derived from naphthaleneacetic acid was identified as naphthaleneacetyl-l-aspartate. The biosynthesis of this conjugate in protoplasts was inducible by naphthaleneacetic acid concentrations found to be cytotoxic under low density growth conditions. However, although it was taken up by cells, the conjugate was not cytotoxic at concentrations as high as 0.2 mm under low density growth conditions. The relationship between conjugation processes and auxin cytotoxicity is discussed.

Abstract
The genetic toxicity of methyl methanethiosulfonate (MMT), a hydrolytic derivative of the insecticide methomyl, or lannate (Du Pont), was studied in Salmonella typhimurium, Saccharomyces cerevisiae and Nicotiana tabacum. At low concentrations, a lethal action was observed in all 3 models. Nuclear genetic effects of the product were not detected on the Xanthi x NC 95 hybrid of N. tabacum or on the diploid strain D7 of S. cerevisiae. At the cytoplasmic level, an effect on chloroplasts was observed on tobacco, but MMT did not induce cytoplasmic 'petites' in yeast. Ames tests with and without metabolic activations by S9 mix and/or fecalase were negative. MMT cannot be considered to be mutagenic on these models; consequently it is unlikely to be genotoxic in man, although these experiments do not exclude eventual co-genetic effects.

Abstract
The action of alpha-fluorinated mescalins on induction of diapause in the cabbage butterfly, Pieris brassicae, has been studied. The introduction of fluorine into mescalin has no influence on this activity. This result suggests solvolysis of fluorine and in vivo formation of a common ethylimine intermediate. Activity decreases, however, with substitution of the nitrogen.
