Introduction: To evaluate the relationship between adherence to the Mediterranean diet (MD) and periphereal artery disease (PAD) in patients with type 2 diabetes mellitus (T2DM)., Methods: An observational sectional study was conducted with 174 patients diagnosed with T2DM, of which 78 patients had PAD. A patient was considered to have PAD if they obtained an ankle-brachial index (ABI) < 0.9 and/or absence of both distal pulses in one of the two feet. Data on sociodemographic and anthropometric variables, physical activity, smoking habits, biochemical blood parameters, and comorbidities were recorded. Good adherence to the MD was considered with a score ≥ 9 in MEDAS-14. Vascular factors independently associated with adherence to the MD in patients with T2DM were identified through multivariate logistic regression analysis., Results: ABI, DFU, intermittent claudication and pedal pulse absence correlated with MD adherence. DFU, intermittent claudication and posterior tibial pulse absence were associated with the final score obtained in the MEDAS-14. Nut consumption, white meat preference and sautéed dish intake were associated with PAD presence. Multivariate analysis linked MD adherence to sex (OR = 0.044, 95 % CI 0.003-0619), age (OR = 0.139, 95 % CI 0.029-0.666), duration of T2DM (OR = 7.383, 95 % CI 1.523-35.779) and age at diagnosis of T2DM (OR = 6082, 95 % IC 1.415-26.136), as well as the presence of DFU (OR = 0.000, 95 % IC 0.000-0.370) and intermittent claudication (OR = 0.004, 95 % IC 0.000-0.534)., Conclusions: Adherence to the MD is associated with a reduction in vascular complications in T2DM, highlighting its potential as a dietary intervention strategy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background/aim: The appropriate sonographic protocol for assessing urate crystal deposits in asymptomatic hyperuricemia (AH) is undefined, as well as how the choice would impact on deposit rates and accompanying sonographic, clinical and laboratory features., Methods: Patients with AH (serum urate ≥7 mg/dL) underwent musculoskeletal ultrasound of 10 locations for OMERACT elementary gout lesions (double contour [DC] signs, tophi, aggregates). Different definitions for AH with deposits were applied, varying according to deposits (any deposits; only DC and/or tophi); gradation (any grade; only grade 2-3 deposits), location (10 locations; 4-joint scheme including knees and 1MTPs; >1 location with deposits), or pre-defined definitions (DC sign in femoral condyles/1MTP and/or tophi in 1MTP). We evaluated crystal deposits rates and compared between other sonographic features, clinical and laboratory variables., Results: Seventy-seven participants with AH showed a median 1 location (IQR 0-2) with tophi, 1 (IQR 1-2) with aggregates, and 0 locations (IQR 0-1) with DC sign. The deposition rate ranged from 23.4% (in >1 location with grade 2-3 DC or tophi) to 87.0% (in any deposit in all 10 locations). Accompanying inflammation - assessed by a positive power-Doppler (PD) signal - and erosions were found in 19.5% and 28.4% of participants, respectively. Positive PD signal was better discriminated by criteria requiring grade 2-3 or >1 location with lesions. Erosions and the different clinical and laboratory variables were similar among protocols., Conclusion: Rates of sonographic deposition in AH varied dramatically among studied protocols, while some could discriminate accompanying inflammation, all highlighting the need for a validated, consensus-based definition., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Mariano Andrés declares speaking fees from Menarini laboratories (below $10,000).

Objective: To describe the inflammatory profile of asymptomatic hyperuricemia (AH) with ultrasound evidence of monosodium urate (MSU) crystals (AH-MSUpos), vs AH without deposits (AH-MSUneg), intercritical gout, and normouricemia., Methods: Based on serum urate levels, musculoskeletal ultrasound, and history of flares, we divided 122 participants into four groups: normouricemia, AH-MSUneg, AH-MSUpos, and intercritical gout. We tested four ultrasound definitions for MSU deposition in AH: grade 2-3 (G2-3) double contour and/or tophi, G1-3 double contour and/or tophi, G1-3 Stewart scheme (double contour sign in knee cartilage and/or first metatarsophalangeal joint and/or tophi in first metatarsophalangeal joint), and G2-3 Stewart scheme. Serum acute phase reactants, cytokines, pyroptosis derivates, and neutrophil-related proteins were measured and compared between groups. A linear regression model was fitted to correlate crystal and inflammatory burden (measured by ultrasound) with inflammatory markers in hyperuricemics., Results: Rates of MSU deposition in AH ranged from 26.0% to 68.8%, depending on the definition used. Levels of CRP, leukocytes, IL-1RA, IL-6, sIL-6R, IL-18, TNF-α, TGF-β, and galectin-3 were higher in hyperuricemics vs normouricemics. Sex, obesity, and comorbidity scores influenced some comparisons. We saw no differences comparing AH-MSUpos  vs AH-MSUneg groups, except for higher calprotectin using G1-3 sonographic definitions and higher CRP and TGF-β when restricted to women and obese participants., Conclusions: Hyperuricemia is associated with substantial inflammation and some degree of active pyroptosis. Four different ultrasound definitions for AH with MSU deposits yielded similar findings, although we noted some differences in calprotectin, CRP, and TGF-β. Sex, obesity, and comorbidities influenced some inflammatory responses., (© The Author(s) 2024. Published by Oxford University Press on behalf of the British Society for Rheumatology.)

Background & Aim: To date, there are no studies demonstrating the impact of the Mediterranean diet on the risk of diabetic foot ulcer. The aim of this research was to examine the connection between adherence to the Mediterranean diet and the level of risk of diabetic foot ulcers in individuals with type 2 diabetes., Methods: Observational pilot study collecting sociodemographic, anthropometric, lifestyle, and type 2 diabetes-related data. Loss of protective sensation was assessed using the Semmes Weinstein 5.07-10 g monofilament, considered altered when not perceived in four points. Vascular status was assessed by palpating pulses and ankle-brachial index, indicating peripheral arterial disease if ankle-brachial index was less than 0.9 or if both pulses were absent. Foot deformities were recorded. The risk of diabetic foot ulcers was stratified into two categories: no risk and risk of diabetic foot ulcers. Adherence to the Mediterranean diet was evaluated using the Mediterranean Diet Adherence Screener-14 questionnaire (good adherence with score >7)., Results: Of the 174 patients with type 2 diabetes mellitus who participated (61.5% men and 38.5% women) with a mean age of 69.56 ± 8.86 years and a mean duration of type 2 diabetes of 15.34 ± 9.83 years. Non-adherent patients to the Mediterranean diet exhibited a higher association of diabetic foot ulcers (p = 0.030) and a lower average score on the Mediterranean Diet Adherence Screener-14 (p = 0.011). Additionally, a lower incidence of diabetic foot ulcers was observed in those who consumed nuts three or more times a week (p = 0.003) and sautéed foods two or more times a week (p = 0.003). Multivariate analysis highlighted the importance of physical activity (OR = 0.25, 95% CI 0.11-0.54; p < 0.001), podiatric treatment (OR = 2.59, 95% CI 1.21-5.56; p = 0.014), and duration of type 2 diabetes (OR = 3.25, 95% CI 1.76-5.99; p < 0.001) as significantly associated factors related to the risk of diabetic foot ulcers., Conclusions: Adhering to the Mediterranean diet correlates with a lower incidence of diabetic foot ulcers in individuals diagnosed with type 2 diabetes mellitus. Furthermore, factors such as regular physical activity, podiatric treatment, and the duration of type 2 diabetes mellitus emerge as pivotal in preventing diabetic foot ulcers., Competing Interests: Conflict of interest The authors declare that they have no competing interests., (Copyright © 2024 The Author(s).

Introduction: Amiodarone-induced thyrotoxicosis (AIT) is a common clinical disorder that may be life threatening and whose clinical manifestations and response to treatment may vary among patients., Methods: We present three patients treated with amiodarone for atrial fibrillation who developed AIT at least 36 months after beginning the treatment. Thyrotoxicosis worsened the underlying cardiac disorders and was resistant to treatment based on the combination of dexamethasone 8-12 mg/day i.v., thioamides 45 mg/day p.o., beta blockers and potassium perchlorate at doses of 800 to 1000 mg per day p.o. Two of the patients attained sustained euthyroidism after 12 and 32 days of combined treatment, while the third required total thyroidectomy., Conclusion: The combination of thioamides with potassium perchlorate is an appropriate form of therapy for AIT in patients resistant to thioamides. The use of this combination should be evaluated in patients with mixed AIT or AIT of unclear etiology., (Copyright © 2010 SEEN. Published by Elsevier Espana. All rights reserved.)

The pathogenesis of pituitary tumours is far to be understood. Pituitary transforming tumour gene (PTTG), a gen that induces aneuploidy, genetic instability, cellular proliferation and to stimulate angiogenesis, has been involved in neoplasic transformation and shown overexpressed in many neoplasm as lung, breast, endometrium, thyroid and colon malignant tumours. On the other hand, PTTG has been inconsistently studied in pituitary tumours. The majority of studies have been performed in animals and there is a great variability in the methods used in its determination. The goal of this review is to resume the role of PTTG in tumourogenesis and critically to revise the studies published in humans in order to advance in the knowledge of the pathogenesis of pituitary adenomas and to find clinical useful predictors of the behavior of these tumours., (Copyright 2010 Sociedad Española de Endocrinología y Nutrición.
