The comes about of the total body scintigraphy filter with iodine-131 and the comes about of thyroid globulin titration were surveyed in 90 patients with separated thyroid cancer and with their follow-up after treatment. Amid the follow-up, backslides were watched in 12 cases, 8 cases (3 cases: ordinary thyroid globulin, 5 cases: tall thyroid gobolin) analyzed by scintigraphy filter and 5 cases with tall thyroid globulin level and the scintigraphy scan negative and backslide was analyzed with the assistance of radiography or ultrasound. Of the 24 cases who gotten sparkle filters demonstrating doubt of repeat, 6 cases were repetitive, whereas as it were 2 of the 63 routinely performed cases were found. It was watched that 10 of the 12 patients who had a backslide were from the tall hazard gather. When considering the typical upper constrain for thyroglobulin 10ng/ml, 3 untrue negative cases were found among patients with backslides, and the number diminished to 1 on the off chance that the upper restrain was considered 5ng/ml.

This study aimed to evaluate the impact of Radioactive iodine 131 (RAI 131) therapy on the quality of life (QoL) of patients with hyperthyroidism using the Thyroid Patient-Reported Outcome (ThyPRO) questionnaire and to quantify the extent of these improvements. This two-year, prospective, single-center study was conducted at the University Medical Faculty Hospital. Eighty-four patients (39 males and 45 females) diagnosed with hyperthyroidism due to Graves' disease, toxic multinodular goiter, or toxic adenoma received RAI 131 therapy at doses of 10, 15, 20, or 30 mCi. The ThyPRO questionnaire, consisting of 84 questions across 12 domains, was administered before treatment and six months post-treatment to assess QoL. The primary outcome was the change in ThyPRO scores. Significant improvements in all post-treatment QoL measures were observed in both males and females (p<0.001). The average age of the patients was 58.33±12.45 years. QoL improvements were consistent across all age groups (<50, 50-60, >60 years) and at all levels of hyperthyroidism severity (mild, moderate, and severe). All RAI 131 dose groups (10, 15, 20, and 30mCi) showed significant improvements in QoL, with no significant differences between dose groups. The correlation analysis revealed that age had a weak negative correlation with QoL improvement (r=-0.20, p=0.05), whereas thyroid hormone levels were significantly correlated with QoL improvement. Multiple regression analysis identified initial ThyPRO score and age as significant predictors of QoL improvement, whereas sex and RAI 131 dose were not significant predictors. RAI therapy significantly enhanced the QoL of hyperthyroid patients according to demographic and disease severity. These findings support the use of RAI 131 as a primary treatment for hyperthyroidism, highlighting the importance of personalized treatment approaches for optimizing patient outcomes. Future research should focus on long-term QoL outcomes and refine therapeutic strategies.

Thyroid cancer is the most common endocrine malignant tumor and accounts for 1% of all cancers. Management of differentiated thyroid carcinoma is total thyroidectomy, followed by iodine-131 (I-131) radioactive iodine (RAI) therapy for thyroid remnant tissue. I-131 whole-body scan helps in the follow-up evaluation in remnant, residual, and recurrence cases. Principle of uptake of I-131 is through sodium-iodide symporter expression on the cells. Physiological uptake of iodine is usually seen in salivary glands and gastrointestinal tract, and false-positive uptakes are seen in lesions such as mucinous cystadenoma, struma ovarii, hepatic, renal, thymic, and meibomian cysts. Here, we present the review of literature of series of cases observed in our department presenting with false-positive uptake of RAI in vertebral hemangioma, lipoma, sinusitis, teratoma, and uterine leiomyoma.

Ectopic thyroid tissue can be present in the embryonal path of descent of the thyroglossal duct anywhere from the foramen caecum to the thyroid gland. However, for such ectopic thyroid tissue to be hyperfunctioning is quite rare. Here, we discuss a 56-year-old female patient who presented with persistent thyrotoxicosis for over 7 years. She had undergone thyroidectomy in 1982 for thyrotoxicosis and was rendered hypothyroid (thyroid-stimulating hormone of 75 μIU/mL). Whole-body technetium scan was done twice which did not show any uptake in the neck or other parts of the body and an empirical dose of 15 mCi of radioiodine therapy was also given to treat the thyrotoxicosis. She continued to be thyrotoxic and was on carbimazole 30 mg/day along with beta-blockers. In 2021, an Iodine131 whole-body scan revealed small remnant thyroid tissue and an ectopic thyroid tissue in a thyroglossal cyst. In such cases of persistent or recurrent thyrotoxicosis despite standard treatments, an ectopic location should be sought after and treated.

Context: The impaired ability of thyroid cancer (TC) cells to uptake and concentrate iodine represents a major therapeutic challenge in malignant TC management. This has been reported probably due to reduced or loss of expression of pendrin in thyroid tumors. Aims: In view of this, we evaluated the pendrin expression in the chemically induced (using N-bis[2-hydroxypropyl] nitrosamine [DHPN]) TC model in Wistar rats. Methods: Uptake in the thyroid gland was evaluated by positron emission tomography with computed tomography (PET-CT) and scintigraphy imaging. Further histopathology (HP) and immunohistochemistry (IHC) were performed for confirming malignancy. Results: The altered uptake in the thyroid gland was observed by PET-CT and scintigraphy imaging. Significant pathological changes in the thyroid were observed using 2-deoxy-2-(fluorine-18) fluoro-D-glucose PET-CT, technetium-99m pertechnetate imaging, and reduced iodine-131 uptake (n = 4) in DHPN-induced animals compared to control indicative of thyroid cell proliferation. In treated groups, tissue HP revealed hyperplastic follicular to papillary cell proliferation with variable mitotic activity. The malignant nature of the tissue and variable uptake of the tracer were further reconfirmed by IHC. IHC revealed reduced pendrin expression in malignant thyroid tissue. Conclusions: Hence, nuclear imaging techniques can be of aid in the early identification and evaluation of cellular changes during the early development of tumor models in laboratory animals. In conclusion, our study reveals that pendrin expression plays a vital role in thyroid uptake, and its reduction was observed in TC in a chemically induced TC model.

Radioiodine capture from nuclear fuel waste and contaminated water sources is of enormous environmental importance, but remains technically challenging. Herein, we demonstrate robust covalent organic frameworks (COFs) with antiparallel stacked structures, excellent radiation resistance, and high binding affinities toward I 2 , CH 3 I, and I 3 − under various conditions. A neutral framework (ACOF-1) achieves a high affinity through the cooperative functions of pyridine-N and hydrazine groups from antiparallel stacking layers, resulting in a high capacity of ~2.16 g/g for I 2 and ~0.74 g/g for CH 3 I at 25 °C under dynamic adsorption conditions. Subsequently, post-synthetic methylation of ACOF-1 converted pyridine-N sites to cationic pyridinium moieties, yielding a cationic framework (namely ACOF-1R) with enhanced capacity for triiodide ion capture from contaminated water. ACOF-1R can rapidly decontaminate iodine polluted groundwater to drinking levels with a high uptake capacity of ~4.46 g/g established through column breakthrough tests. The cooperative functions of specific binding moieties make ACOF-1 and ACOF-1R promising adsorbents for radioiodine pollutants treatment under practical conditions. Radioiodine capture from nuclear fuel waste and contaminated water sources is of environmental importance but technically challenging. Here, the authors report covalent organic frameworks with antiparallel eclipsed stacked structures with dynamic adsorption performance for iodine pollutants under various conditions.

Radioactive iodine 131 ((131)I) therapy has long been used in the treatment of differentiated thyroid cancers (DTC). While salivary and lacrimal glandular complications secondary to (131)I therapy are well documented, there is little in the literature addressing nasolacrimal duct obstruction (NLDO). We aimed to evaluate the frequency of (131)I therapy-acquired NLDO, its correlation to (131)I therapy doses, and the surgical treatment outcome of this rare side effect. From 2000-2012, a retrospective review of 864 among 1,192 patients with confirmed DTC who were treated with (131)I therapy was performed to examine the frequency of NLDO, its causative factors, as well as imaging, surgical intervention, and outcomes. Nineteen (2.2%) patients were identified with NLDO. The mean age was 51.9±10.5 years (range: 39-72 years). Fifteen (78.9%) were female and four were male (21.1%). The mean individual (131)I doses were 311.1±169.3 millicurie (mCi) (range: 150-600 mCi). The mean duration between the date of (131)I therapy and the occurrence of NLDO was 11.6±4.1 months (range: 6.5-20). Fourteen (73.7%) patients had bilateral epiphora. Computed tomography dacryography allowed for the detection of all NLDO. Eighteen (94.7%) patients underwent dacryocystorhinostomy. Complete recovery was obtained in 14 (73.7%) patients. Age >45 years and (131)I therapy doses >150 mCi were significantly correlated with NLDO (P=0.02 and P=0.03, respectively). NLDO is an underestimated complication of (131)I therapy in DTC patients. Clinicians should be aware of this rare complication for prompt intervention.

Metal–organic frameworks (MOFs) are useful synthetic materials that are built by the programmed assembly of metal nodes and organic linkers 1 . The success of MOFs results from the isoreticular principle 2 , which allows families of structurally analogous frameworks to be built in a predictable way. This relies on directional coordinate covalent bonding to define the framework geometry. However, isoreticular strategies do not translate to other common crystalline solids, such as organic salts 3 – 5 , in which the intermolecular ionic bonding is less directional. Here we show that chemical knowledge can be combined with computational crystal-structure prediction 6 (CSP) to design porous organic ammonium halide salts that contain no metals. The nodes in these salt frameworks are tightly packed ionic clusters that direct the materials to crystallize in specific ways, as demonstrated by the presence of well-defined spikes of low-energy, low-density isoreticular structures on the predicted lattice energy landscapes 7 , 8 . These energy landscapes allow us to select combinations of cations and anions that will form thermodynamically stable, porous salt frameworks with channel sizes, functionalities and geometries that can be predicted a priori. Some of these porous salts adsorb molecular guests such as iodine in quantities that exceed those of most MOFs, and this could be useful for applications such as radio-iodine capture 9 – 12 . More generally, the synthesis of these salts is scalable, involving simple acid–base neutralization, and the strategy makes it possible to create a family of non-metal organic frameworks that combine high ionic charge density with permanent porosity. The use of computational crystal-structure prediction has enabled the targeted assembly of frameworks of porous organic ammonium halide salts that have many of the qualities of metal–organic frameworks despite containing no metal.

We looked into the restorative records of patients with Graves’ hyperthyroidism who were treated with iodine-131 between 1996 and 2002. Of the 135 patients, satisfactory data was gotten on the comes about of at slightest 24-month follow-up in 70 of them. Iodine-131 was given in a single measurements at a rate (200 microcuries/g of organ weight redressed to 100% iodine take-up after 24 hours). Methimazole treatment was suspended a week some time recently the organization of iodine-131. Treatment was considered fruitful with either or hypothyroidism. In follow-up examinations conducted after 12 months of application of the treatment, 81.2% of treatment victory rates were found, whereas in examinations conducted after 24 months, the rate come to 88.3%. This near the rates shown in the various sources.

Considering the importance of sustainable nuclear energy, effective management of radioactive nuclear waste, such as sequestration of radioiodine has inflicted a significant research attention in recent years. Despite the fact that materials have been reported for the adsorption of iodine, development of effective adsorbent with significantly improved segregation properties for widespread practical applications still remain exceedingly difficult due to lack of proper design strategies. Herein, utilizing unique hybridization synthetic strategy, a composite crystalline aerogel material has been fabricated by covalent stepping of an amino-functionalized stable cationic discrete metal-organic polyhedra with dual-pore containing imine-functionalized covalent organic framework. The ultralight hybrid composite exhibits large surface area with hierarchical macro-micro porosity and multifunctional binding sites, which collectively interact with iodine. The developed nano-adsorbent demonstrate ultrahigh vapor and aqueous-phase iodine adsorption capacities of 9.98 g.g −1 and 4.74 g.g −1 , respectively, in static conditions with fast adsorption kinetics, high retention efficiency, reusability and recovery. The development of effective adsorbents of radioiodine nuclear waste remains difficult due to the lack of proper material design strategies. Here the authors report an ultralight hierarchically porous crystalline multifunctional hybrid nanocomposite for ultrafast entrapment of iodine and polyiodide species under both static and dynamic condition.
