The Role of TPOAb in Thyroid-Associated Orbitopathy: A Systematic Review.

INTRODUCTION: Thyroid-associated orbitopathy (TAO) is one of the most common autoimmune inflammatory disorders of the orbit. The presence of anti-thyroid antibodies is believed to play a role in the pathogenesis and clinical status of the TAO patients. Herein, we review the usefulness of TPOAb as a biomarker for TAO. METHODS: A systematic search in MEDLINE library was conducted. Results: Twenty studies were included. TPO is expressed in orbital tissues, and the polymorphism rs11675434 SNP has proven to be associated with clinically evident TAO. Studies in pediatric patients have shown a positive correlation between high TPOAb levels and TAO. In contrast, results in adults are inconsistent. Some studies imply a protective role of TPOAb, yet the majority did not find any association. Some authors have suggested an implication of TPOAb in the pathophysiology of TAO in TRAb-negative patients. CONCLUSIONS: The role of TPOAb in TAO remains unclear and controversial.

Medical Flossing and the Pilates Method: Their Effectiveness on the Strength, Endurance, and Functionality of Healthy Individuals.

The flossing method is an emerging therapeutic intervention based on the use of a floss-band that is circumnavigated at the various points of the body being treated. It is optimally combined with an appropriate exercise program to induce ischemia and release the fascia by applying pressure and movement to functional models. The Pilates method teaches the person to focus on the muscles, especially those responsible for the correct posture. It also helps the individual to become aware of the way he/she breathes. Both methods have positive effects on exercise and rehabilitation. However, medical flossing has not been as well researched as the Pilates method. This study aims to examine the effectiveness of both methods on the strength, endurance, and functionality of healthy individuals. A review of the literature on medical flossing and Pilates was conducted. A systematic research took place from 2014 to 2019. Publications in non-English or non-Greek language were excluded. The articles were retrieved from not only PubMed, Scielo, and Elsevier databases, but also Google Scholar. Both methods are understudied in relation to their effectiveness on the strength, endurance, and functionality of healthy individuals. More studies are required to estimate the effects of both methods on healthy individuals.

Cushing's syndrome in pregnancy: a review of reported cases.

Cushing's syndrome (CS) causes hypogonadotropic hypogonadism and anovulatory infertility due to hypercortisolism, and it is very rare in pregnancy. CS in pregnancy is associated with important maternal-foetal morbidity and mortality, such as preeclampsia and premature delivery. A systematic search was conducted in the MEDLINE library to retrieve articles reporting cases of CS in pregnant women, during the period between 2010 and 2020.Thirty-five reported cases are presented focusing on the ability of diagnosis, treatment therapies, and foetal outcomes. Diagnosis of CS during pregnancy can be challenging and is often delayed, adrenal adenoma being the predominant cause. Both medical treatment and surgery aiming at restoring the cortisol balance reduce maternal and foetal complications.

PCSK9 Antibody-based Treatment Strategies for Patients With Statin Intolerance.

BACKGROUND: Statin intolerance refers to the inability of a patient to tolerate statin therapy, presenting muscle aches, pains, weakness and muscle inflammation. Thus, numerous patients are not treated with suitable statin-based therapy or take only very low doses. As a result, the desired decrease in low-density lipoprotein cholesterol (LDL-C) is not achieved, resulting in patients at a high risk for cardiovascular events, requiring an alternative lipid-lowering treatment. Common treatments manage to reduce the LDL-C level by up to 20%. Recently, new alternative treatment options have been proved to lower the LDL-C level by up to 70%. These treatment strategies are based on human monoclonal antibodies against protein convertase subtilisin/kexin 9 (PCSK9). MATERIALS AND METHODS: Herein, we review the efficiency of anti-PCSK9 in treatment of hypercholesterolemic patients with statin intolerance. We focused on the use of PCSK9 inhibitors in statin-intolerant patients and we estimated the clinical results concerning the reduction of the mean LDL-C concentration and the side effects that were observed. RESULTS: In the majority of cases, treatment strategy based on PCSK9 was successful and achieved the end-points. CONCLUSION: PCSK9 inhibition can be considered as a treatment of option for lipid-lowering in statin-intolerant patients.

The Impact of Peripheral Eosinophil Counts and Eosinophil to Lymphocyte Ratio (ELR) in the Clinical Course of COVID-19 Patients: A Retrospective Study.

BACKGROUND/AIM: Eosinophils are blood cells responsible for response against parasites and allergens. Eosinophil to lymphocyte ratio (ELR) is a biomarker for inflammatory conditions. Our aim was to evaluate the role of eosinophils and ELR in COVID-19 patients. PATIENTS AND METHODS: The study included 96 patients hospitalized with COVID-19. They were classified into moderate to severe cases and critical cases. Eosinophils and ELR were determined in both groups, in patients that died or survived and were correlated to duration of hospitalization. RESULTS: There was a statistically significant decrease in eosinophils and ELR between patients that died and patients that survived (p<0.05), and in mean values of the two biomarkers (p<0.05 for eosinophils and p<0.05 for ELR) between patients hospitalized for more or less than 15 days among those with moderate to severe disease. CONCLUSION: Lower eosinophil counts and ERL could probably predict worse outcome in COVID-19 patients.

Concomitant Existence of Bilateral Adrenal Adenomas. To Operate or Not?

Nowadays, through the wide use of both magnetic resonance imaging and computed tomography, the diagnosis of adrenal incidentaloma is becoming increasingly frequent. Pheochromocytomas are neuroendocrine tumors which produce catecholamine, and they are characterized by headaches, palpitations, sweating and hypertension. Aldosterone-secreting adrenal cortical adenomas can cause various metabolic and cardiovascular diseases due to aldosterone excess. Our aim is to present a rare case of a concomitant existence of pheochromocytoma in the right adrenal and a functioning adrenal cortical adenoma in the left, worthwhile mentioning since the appearance of these two entities in different location in the same patient is unprecedented. The treatment remains challenging.

Lipid-lowering Drugs and Neurocognitive Function: A Systematic Review.

BACKGROUND/AIM: Lipid-lowering drugs have been suggested to affect neurocognitive function. This review aimed to give the latest evidence on the way these agents affect neurocognitive function based on clinical trials. MATERIALS AND METHODS: A systematic search concerning original studies from 2015 to 2020 was performed through the databases PubMed, EMBASE and Cochrane, according to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. The trials enrolled numerous patients and were conducted in different areas of the world. The terms used are cholesterol, lipid-lowering drugs, statins and cognitive function. RESULTS: Eleven randomized trials met the inclusion criteria. The trials included patients suffering from cardiovascular conditions. In particular, patients with coronary heart disease, coronary heart disease risk equivalents and hypercholesterolemia were tested. The trials included evolocumab, alirocumab, statin, ezetimibe or placebo. CONCLUSION: Lipid-lowering drugs seem to have no significant effect on neurocognitive function, but further research specifically focused on this matter is needed.

Estudio comparativo de la aplicación de la calibración FRIDEX y de la guía NOGG en el manejo de la osteoporosis en la práctica clínica habitual / A comparative study between the implementation of the FRIDEX calibration and the NOGG guideline in the management of osteoporosis in routine clinical practice

Objetivo. En España, el estudio FRIDEX ha aportado recientemente unos umbrales de riesgo coste-efectivos para el manejo de la osteoporosis. El objetivo del estudio es evaluar el impacto de su aplicación en la práctica clínica habitual, comparándola también con los umbrales de la National Osteoporosis Guidelines Group (NOGG). Material y métodos. Estudio transversal realizado en mujeres remitidas a una unidad de densitometría ósea. El riesgo absoluto de presentar una fractura mayor o de cadera se calculó mediante la fórmula FRAX® española y británica para poder emplear los umbrales de intervención de la calibración FRIDEX y de la guía NOGG, respectivamente. Se descartaron mujeres con tratamiento antirresortivo. Resultados. Fueron incluidas 607 mujeres con una mediana de edad de 59,4 (RIQ=14) años. El 31,4% recibieron tratamiento después de la densitometría ósea. El empleo de la calibración FRIDEX indicaría una densitometría ósea al 35,4% y tratamiento al 26,7%, lo que supondría una reducción de gastos a los 5años del 18,8%. Según la guía NOGG precisarían densitometría ósea el 32% y tratamiento el 21,3%, siendo el ahorro de un 35% a los 5años respeto a la actitud habitual. La concordancia de la guía NOGG y del FRIDEX según el coeficiente kappa de Cohen fue baja tanto a nivel diagnóstico (0,16 [IC95%: 0,09-0,24]) como terapéutico (0,39 [IC95%: 0,31-0,47]). Conclusiones. La aplicación de la calibración FRIDEX y de la guía NOGG aumentaría la eficiencia del manejo de la osteoporosis, aunque su concordancia es baja, indicando tratamiento en diferentes perfiles de mujeres (AU)

Objective. The recent FRIDEX calibration proposed cost-effectiveness thresholds for the Spanish population. The aim of our study is to evaluate the impact of its application in routine clinical practice and to compare its thresholds with those of the National Osteoporosis Guideline Group (NOGG). Material and methods. Cross-sectional study in women referred to a bone densitometry unit who were not receiving antiresorptive therapy. The absolute risk of major fracture or hip fracture was calculated with the Spanish and British formulas of the FRAX® tool using the intervention thresholds of the FRIDEX calibration and the NOGG guideline, respectively. Results. The study included 607 women with a median age of 59.4 (IQR=14) years. Treatment was initiated in 31.4% after bone mineral densitometry. With the application of the FRIDEX calibration, bone mineral density testing would have been indicated in 35.4% of the sample and treatment in 26.7%, reducing costs by 18.8% over a 5-year period. The NOGG guideline would have recommended testing in 32% and treatment in 21.3% of the participants, resulting in a reduction in costs of 35% over 5years, when compared with the standard approach. Agreement between the FRIDEX calibration and the NOGG guideline, as defined by Cohen's kappa coefficient, was low in terms of both diagnostic (0.16 [95%CI, 0.09-0.24]) and therapeutic indications (0.39 [95%CI, 0.31-0.47]). Conclusions. The application of the FRIDEX calibration and the NOGG guideline improves efficiency in the management of osteoporosis, although the level of agreement between the two is low (AU)

The Anti-Inflammatory Effects of Statins on Coronary Artery Disease: An Updated Review of the Literature.

BACKGROUND: Statins have long been used for the protection against coronary artery disease (CAD). Their beneficial effect apart from cholesterol reduction lies in their pleiotropic properties. Emerging evidence from laboratory studies and clinical trials as well have pointed out the pivotal role of inflammation on the initiation and exacerbation of atherosclerosis; a major cause of CAD. Inflammation markers such as high sensitivity C-reactive protein and adhesion molecules are shown to increase in CAD patients and are used as prognostic tools. It is well known that statins can actually reduce the circulating levels of these agents slowing therefore the inflammatory process; interestingly not all types have the same outcome. CONCLUSION: The anti-inflammatory effect of statins on the formation of atherosclerotic plaque and the function of endothelial cells is thus of particular importance as these agents can actually ameliorate CAD prognosis.
