What the literature leaves open

  • Thyroid function tests (TSH, FT4, and FT3 where available) should be included in the standard diagnostic workup of all patients presenting with new-onset atrial fibrillation, unexplained tachycardia (HR >120 bpm), or heart failure without clear conventional cardiovascular etiology, regardless of patient age. 2. The Wayne Index and/or Burch-Wartofsky Point Scale should be routinely applied by clinicians at all hospital levels when thyrotoxicosis or thyroid storm is suspected, to facilitate rapid triage and appropriate escalation of care. © The Indonesian Journal of General Medicine 167 Research Article Volume 43, Issue No.01. 2026 ISSN: 3048-104X 3. Multidisciplinary management involving internal medicine specialists, cardiologists, and endocrinologists is essential for optimal outcomes in thyroid storm complicated by cardiac decompensation. 4. Echocardiography is strongly recommended in all patients with suspected thyrotoxic cardiomyopathy to objectively quantify left ventricular systolic and diastolic function, guide management intensity, and provide a baseline for monitoring cardiac functional recovery. 5. Beta-blockade in the context of AF RVR complicating thyroid storm and suspected cardiomyopathy must be approached with caution; intravenous esmolol (short-acting, titratable) or intravenous amiodarone (after antithyroid drug administration) should be preferred over nonselective oral beta-blockers when significant cardiac dysfunction is suspected. 6. Long-term antithyroid therapy with periodic thyroid function monitoring, and eventual definitive therapy (radioiodine ablation or thyroidectomy), should be pursued following stabilization, to prevent recurrence.

  • The greatest strength of this study was the ability to triangulate the evidence across study methods, by doing this we were able to reduce the risk of residual confounding and reverse causation. The concor- dance of the negative results in triangulation evidence from observational and MR studies supports that there may be no causal association between thyroid function in euthyroid persons and risk of sepsis. Another strength is the population-based design, which allowed us to examine habitual thyroid function in relation to risk of sepsis, rather than potentially suppressed TSH levels reflecting non-thyroidal illness in studies recruiting participants from clinical settings. However, in the observational analyses participants self-report of thyroid disease might have introduced recall bias, which in modern epidemiology is thought to bias the hazard ratio towards the null (32). Further, we did not have information on whether participants started treatment for potential thyroid conditions after participation. Participants with deviant thyroid hormone levels were advised to visit their general practitioners, and we also did not have repeated measurements of TSH. Lastly, in the MR analysis we are not able to formally address the possibility of non- linearity, due to limitations in the current methodology for performing such analyses (33). In theory, the observed flat linear regression line could therefore mask a J- or U-shaped association between genetically predicted TSH-levels and risk of sepsis. However, we observed no association between genetic liability to either low or high TSH-levels and risk of sepsis, which does not support a non-linear association with TSH as the exposure.

  • Although the study was conducted using a rigorous methodology, certain limitations should be acknowledged. The applied random method for subject selection, the partially identical subjects across the different 154 LITHIUM AND SELENIUM CONCENTRATIONS IN THE DRINKING WATERS OF A MOUNTAINOUS VILLAGE: POTENTIAL RELATIONSHIP TO RESIDUAL THYROID PATHOLOGY groups, the relatively small sample size, and the various times of determination could influence the results. Similarly, we do not know the conditions before the introduction of iodination in different settlements, only the global situation of the Upper Mureș Valley. Nevertheless, it can be assumed that iodine deficiency was more severe in the mountainous region (Săcalu de Pădure) than in the flat areas (Brâncovenești, Lueriu). Due to time and resource constraints, the study focused only on the most relevant variables. Yet, the results provide valuable insights into the investigated phenomenon and serve as a basis for further research.

  • The key strength of this study is its large sample size and its novel focus on thyroid function changes, as well as the potential clinical applicability of the findings. Unlike previous research that relied on single time-point assessments, we proposed, for the first time, a two points based classification method using changes in TSH and FT4 from early to late pregnancy, enabling intuitive differentiation of maternal thyroid function status. This classification framework is easy to implement. It is especially useful for identifying women whose thyroid function appears normal in both early and late pregnancy but shows high-risk trends over time, enabling earlier risk stratification and guiding targeted monitoring or preventive interventions. Furthermore, rigorous statistical methods were employed, including data-driven threshold effect analysis to determine cut-off values, multiple sensitivity analyses to validate the robustness of the classifi- cation. However, several limitations regarding potential confounders should be considered. First, while we adjusted for major factors including maternal age, pre-pregnancy BMI, parity, GDM, smoking status, alcohol consumption, and early-onset preeclampsia, residual confounding may still remain due to the retrospective design.

  • Several limitations warrant consideration. First, the retrospec- tive design inherently relied on historical clinical data and limited control over potential unmeasured confounders. Second, thyroid volume estimation by ultrasound is operator-dependent, and inter- and intra-observer variability were not formally assessed in this study. Third, although overall cohort size was substantial, stratifi- cation by baseline thyroid volume and administered activity re- sulted in small sample sizes within the largest gland volume tiers, thereby limiting statistical power in patients with markedly en- larged thyroid glands. Finally, systemic symptoms such as palpita- tions, diarrhea, or fever were not included in the routine adverse event assessment checklist, as these events are rare following RAI therapy in Graves’ disease, and future prospective studies should incorporate a more comprehensive symptom assessment.

  • Use of AI with novel biomarkers Recent advances in AI have opened new avenues for identifying and integrating novel biomarkers to refine cardiovascular risk prediction in individuals with thyroid dysfunction Beyond traditional lipid indices such as non- HDL cholesterol and NHHR, Al-driven models now incorporate multidimensional data-including inflammatory markers (e.g., hs-CRP, IL-6), oxidative stress indicators, metabolomic signatures and genetic profiles to uncover subtle, non-linear associations between thyroid hormone imbalance and cardiovascular pathology. Machine learning algorithms, particularly deep learning and ensemble methods can analyze large-scale datasets to detect early patterns of endothelia dysfunction, subclinical atherosclerosis, and cardiometabolic derangements that may not be apparent through conventional statistical approaches. Emerging studies up to 2026 suggest that Al-assisted biomarker panels significantly enhance risk stratification by enabling personalized prediction models, thereby facilitating earlier intervention and targeted therapeutic strategies in this high-risk population. Importantly, such approaches also allow dynamic risk assessment by continuously integrating longitudinal patient data, marking a shift from static to adaptive cardiovascular risk evaluation in thyroid disorders CONCLUSION lipid profile markers and All atherogenic indices examined showed a significant correlation with thyroid hormones in individuals with thyroid dysfunction. Both non-HDL-C and NHHR are important biomarkers for individuals who have thyroid dysfunction. assessing However, the NHHR outperformed traditional lipid parameters and other atherogenic indices, making it a more sensitive indicator of dyslipidemia and CVD risk assessment. The study emphasized the importance of monitoring lipid levels with atherogenic indices to prevent or reduce the incidence of CVD in individuals with thyroid dysfunction.
