Several international consortia launched already Genome wide Association Studies (GWAS) and whole genome sequencing strategies to identify genetic markers with immediate application in patients at risk of respiratory failure. These new genetic data are important not only for understanding susceptibility factors for COVID-19 but they also contain an important message of hope for mankind warranting our survival and health.
A persistently elevated thyroid stimulating hormone (TSH) level is a common clinical problem in primary hypothyroidism patients treated with levothyroxine (LT4). „Pseudomalabsorption”, which is characterized by poor adherence,should be considered in cases of refractory hypothyroidism after excluding other causes, such as malabsorption.
We reviewed the features of the patients with persistently elevated TSH despite high-dose LT4 therapy.
Symptom evaluation, medications, comorbid diseases and physical examination features of five patients who applied to our outpatient clinic between 2016-2019 and diagnosed with LT4 pseudomalabsorption were retrospectively analyzed.
The LT4 loading test was performed with an oral dose of 1,000 µg LT4. Demographic parameters, BMI, thyroid function tests, laboratory parameters for malabsorption were recorded.
We observed at least two-fold increase of free thyroxine levels during the test, which was considered pseudomalabsorption. Euthyroidism was achieved in two patients by increasing the LT4 dosage and in one patient with a change in the preparation. TSH decreased significantly after being informed about compliance in one patient. Another one was given LT4 twice weekly, but TSH remained elevated because of nonadherence.
The LT4 loading/absorption test is a valuable tool to confirm the diagnosis of pseudomalabsorption. Informing patients, changing the preparation, increasing the dose, supervised intake of daily/weekly LT4 forms are treatment options for managing these cases.

The frequency of subclinical hypothyroidism (SH) in patients with obesity is increased compared with the normal population. However, data on the risk of cardiovascular disease (CVD) in patients with SH are still scarce. Lipid parameters are strong predictors of early CVD. We aimed to investigate the role of lipid indices in predicting CVD risk compared to conventional lipid components.
A total of 220 euthyroid obese children (EU) and 90 obese children with SH were included in the study. All data were collected from hospital files. Lipid indices were evaluated. Atherogenic index of plasma (AIP), cardiac risk ratio (CRR) and atherogenic coefficient (AC) were calculated. AIP>0.24, CRR>5 ve AC>3 were considered as cardiovascular risk criteria.
The presence of SH increased the risk of higher AIP and the risk of CRR, compared to euthyroid obese children.
Subclinical hypothyroidism in obese children may cause dislipidemia carrying a high cardiovascular disease risk.

The
I activity for treating Graves’ disease (GD) is usually determined based on physician’s experience.
This study aimed to design an empirical method that was not only personalized and quantitative, but also simple, convenient, and easy to grasp.
The study population comprised patients with GD, selected between May 2013 and May 2016, who received
I therapy in the Outpatient Department of Shanghai Ninth People’s Hospital. The first-visit patients of physician 1 were placed in the traditional group the activity of
I (mCi) was calculated using the routine formula [empirical activity (0.07-0.12 mCi/g) × thyroid mass]/[24-h thyroid
I uptake]. The first-visit patients of physician 2 were placed in the personalized group. The activity of
I (mCi) was calculated in two steps. First, the initial activity was calculated 0.1 mCi/g × thyroid mass (g), and then a personalized and quantitative calibration table of
I activity was used to obtain a final
I activity. The cure rate with a single activity of
I was recorded 1 year later.
The traditional and personalized groups included 241 and 282 patients, respectively. Interestingly, the personalized group achieved a higher cure rate [86.5% (244/282)
73.4% (177/241), P = 0.000] with a relatively higher
I activity for the first treatment [8.7 (7, 3.5-30) mCi
6.7(6, 2.5-30) mCi, P = 0.000] compared with the traditional group, while the incidence rate of permanent hypothyroidism was not significantly different between the two groups (P = 0.175).
The empirical method designed in this study was reliable.

As the life expectancy prolongs, malignancy has become an important issue in renal transplant recipients (RTRs). Thyroid cancer is the most common endocrine malignancy with ongoing increase in incidence all over the world.
This is a cross-sectional study that investigates the thyroid disorders and the prevalence of thyroid nodule and cancer in RTRs.
204 RTRs were evaluated for the thyroid diseases with ultrasonography, serum thyroid stimulating hormone, free T4, free T3 levels, anti-thyroglobulin antibody and anti-thyroid peroxidase antibody levels; FNAB was carried if required.
191 patients (94.1%) had normal thyroid function. Subclinical hypothyroidism was diagnosed in 11 patients, subclinical hyperthyroidism in 1 patient and low T3 syndrome in 4 patients. The FNAB was performed in 17 (27.9%) from 61 patients with thyroid nodule. The cytological examination of biopsy materials revealed that 2 (11.8%) nodules were suspicious for malignancy, 13 (76.5%) were benign, and 2 (11.8%) with non diagnostic cytology. Thyroid cancer prevalence was 0.2% in Turkey but we detected that 0.98% of RTRs had thyroid cancer.
Screening the RTRs for thyroid disorders is necessary, so that early diagnosis and appropriate treatment of thyroid disease and cancer may improve the quality of life.

The variety of tumor-seeking radiopharmaceuticals, which are currently in clinical use, may have a potential role as imaging agents for adrenal gland tumors, due to physiological characteristics of this organ.
The purpose of this study was to evaluate the diagnostic potential of
Tc-HYNIC-TOC,
Tc(V)-DMSA, and
Tc-MIBI in the assessment of adrenal tumors, by correlating with imaging findings and histopathologic results.
The research is designed as a cross-sectional prospective study.
The study included 50 patients with adrenal tumors (19 hormone-secreting and 31 nonfunctioning) and 23 controls without adrenal involvement. In all patients, single-photon emission computed tomography (SPECT) was performed, using qualitative and semiquantitative analysis. The tumor to non-tumor tracer uptake was conducted by using a region-of-interest technique. Adrenal to background (A/B) ratio was calculated in all cases.
Tc-HYNIC-TOC scintigraphy showed a high statistical significance between A/B ratios, while other two tracers resulted in a lower sensitivity, specificity and accuracy. Futhermore,
Tc-HYNIC-TOC could have a high diagnostic yield to detect adrenal tumors (the receiver-operating-characteristic curve analysis, A/B ratio cut-off value of 8.40).
A semiquantitative SPECT analysis showed that
Tc-HYNIC-TOC is a highly sensitive tumor-seeking agent for the accurate localization of adrenal tumors.
A semiquantitative SPECT analysis showed that 99mTc-HYNIC-TOC is a highly sensitive tumor-seeking agent for the accurate localization of adrenal tumors.
Estimation of intensive care unit (ICU) length of stay time (LOS) may be challenging, and pro-inflammatory cytokines can be used as a marker for this purpose.
The current study aimed to investigate the association between pro-inflammatory cytokine levels and LOS in hyperglycemic patients admitted to adult ICU.
This is a prospective observational study.
All adult ICU patients with a blood glucose level higher than 250 mg/dL, during the study period were included. Hospitalization day demographics were recorded, and plasma IL-6, IL1-ß, and TNF-α concentrations were measured.
A total of 74 patients were enrolled in the study. Diabetic ketoacidosis (DKA) was positive in 31 patients, and the remaining 43 were in the non-DKA (NDKA) group. There was no difference between the two groups in terms of age, gender, LOS, hemoglobin, hematocrit, lactate levels, and platelets count. IL-6, IL-1ß, and TNF-α levels did not show any difference between DKA and NDKA groups (p=0.784, 0.413, and 0.288, respectively). There was a positive correlation between IL-6 levels and LOS (n=74, Pearson correlation=0.330; p=0.004).
Among pro-inflammatory cytokines, IL-6 showed a better performance for the prediction of LOS than IL-1ß, TNF-α, and CRP.

The pituitary gland serves as the center of the endocrine system. Stem cells are typically found in a specialized microenvironment of the tissue, called the niche, which regulates their maintenance, self-renewal, fate determination, and reaction to external influences. The aim of this study is to elucidate the role of stem cells in the initiation, invasion, and progression of pituitary adenomas.
All specimens were collected between January 2007 and April 2015. Radiological classification (invasiveness) for all cases was performed according to the Wilson-Hardy classification system. Immunohistochemical staining was performed to all specimens for CD133, Oct4, Sox2 and nestin.
The study included 48 patients. Of 48 patients, 17 (35.4%) were male and 31 (64.6%) were female. Mean age is 47.10±14.14 (17-86 yrs.). According to the Wilson-Hardy classification system, 27 (56.3%) were non-invasive adenomas. There was no statistical significance between the expression of pituitary stem cell markers (CD133, OCT4, SOX2, nestin) and invasiveness.
All stem cell markers are stained extensively in pituitary adenomas, except for SOX2 which was stained weakly. However, there is no effect of stem cells on invasiveness of pituitary adenomas because we cannot find a difference of the staining level between invasive and non-invasive adenomas. Nestin was stained extensively in functional adenomas, especially for GH, PRL, and gonadotropin secreting adenomas. SOX2 was stained extensively for ACTH-secreting adenomas.
