BACKGROUND: Clinical manifestations of thyroid dysfunction are variable. The UST Scoring Index for thyroid disorders, formulated in the 1990s to evaluate thyroid functional status, was based on total thyroid hormone levels and thyroidal iodine uptake. However, with the advent of newer and more sensitive tests, the recommendations and practice now dictate the use of thyrotropin (TSH) and free thyroxine (FT4) levels in the confirmation of thyroid dysfunction.
OBJECTIVE: To validate the UST Scoring Index for thyroid disorders using TSH and FT4.
METHODS/RESULTS: The UST Clinical Scoring Index was administered to 170 patients presenting for thyroid-relatedcomplaints. Thyroid function tests were then requested (TSH and Free T4) and they were classified according to biochemical status. We obtained the following: 43 hyperthyroid, 102 euthyroid and 25 hypothyroid subjects. The mean TSH for the 3 groups were 0.08, 1.28, and 41.50 uIU/mL respectively (NV 0.27-3.75.) Mean FT4 levels were 36.18, 18.33, and 8.43 pM/L respectively (NV 10.3-25.0.) The most frequent findings in the biochemically hyperthyroid group were thyroid enlargement (88%), easy tiredness (74%), palpitations (70%), and nervousness (65%); in the euthyroid group, easy tiredness (62%), thyroid enlargement (54%), palpitations (53%), and irritability (49%); in the hypothyroid group, easy tiredness (64%), exertional dyspnea (52%), weight gain (44%), and constipation (44%.) The UST scoring index for thyroid disorders has a sensitivity of 67%, specificity of 84%, and accuracy rate of 80 %, with AUC of 0.850 on ROC analysis for the detection ofhyperthyroidism. For detecting hypothyroidism, it has a sensitivity of 40%, specificity of 92%, and asccuracy rate of 85%, with AUC 0.7553 on ROC analysis.
CONCLUSION: The UST scoring index for thyroid disorders has good sensitivity, specificity and accuracy rate based on ROC when validated using TSH and FT4 for the detection of hyperthyroidism and hypothyroidism.

BACKGROUND: Atrial fibrillation (AF) commonly occurs in association with chronic kidney disease (CKD), resulting in adverse outcomes. Combining pulmonary vein isolation (PVI) and renal sympathetic denervation (RSD) may reduce the recurrence of AF in patients with CKD and hypertension. We considered that RSD could reduce the recurrence of AF in patients with CKD by modulating sympathetic hyperactivity. Our goal was to compare the impact of PVI + RSD with that of PVI alone in patients with concurrent AF and CKD. METHODS: This was a single-center, prospective, longitudinal, randomized, double-blind study. Forty-five patients with controlled hypertension, symptomatic paroxysmal AF and/or persistent AF, stage 2 or 3 CKD, and a dual-chamber pacemaker were enrolled from January 2014 to January 2015. We assessed the 30-second recurrence of AF recorded by the pacemaker, 24-hour ambulatory blood pressure measurements, estimated glomerular filtration rate, albuminuria, echocardiographic parameters, and safety of RSD. RESULTS: No patient developed procedural or other complications. The ambulatory blood pressure measurements did not differ within the PVI + RSD group or between the PVI + RSD and PVI groups throughout the study. Significantly more patients in the PVI + RSD group than in the PVI group were free of AF at the 12-month follow-up evaluation. The PVI group had an unacceptable response to ablation with respect to changes in echocardiographic parameters, whereas these parameters improved in the PVI + RSD group. CONCLUSION: PVI + RSD were associated with a lower AF recurrence rate than PVI alone; it also improved renal function and some echocardiographic parameters. These encouraging data will serve as baseline information for further long-term studies on larger patient populations.

Background: and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. Methods: We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). Results: There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. Conclusions During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.
