Tumor microenvironment in thyroid cancer: Immune cells, patterns, and novel treatments

The tumor immune microenvironment of thyroid cancer is the heterogeneous histological space in which tumor cells coexist with host cells. Published data from this review were identified by search and selection database of Pubmed, Elsevier, and Science Direct. Searching was made in two steps using different keywords. In thyroid pathology, the inflammatory response is very important, and might have a key role finding new diagnostic and therapeutic methods, particularly in thyroid cancer. Different immune cells may be more or less present in different types of thyroid cancer and may even have different functions, hence the importance of knowing their presence in different thyroid tumor pathologies. Cancer-related inflammation could be a useful target for new diagnostic and therapeutic strategies by analyzing peritumoral and intratumoral immune cells in different types of thyroid tumors. Moreover, novel strategies for thyroid cancer treatments, such as monoclonal antibodies targeting checkpoint inhibitors, are emerging as promising alternatives.

Improvement of mood and sleep quality in patients with primary hyperparathyroidism after parathyroidectomy: A prospective case-control study

BACKGROUND

Primary hyperparathyroidism can impact patient quality of life with psychopathological symptoms like mood and sleep disturbances. In the latest recommendations published according to the primary hyperparathyroidism surgical consensus, these neuropsychological symptoms continue to be excluded. This study aims to assess the negative effects of mood and sleep on patients with primary hyperparathyroidism compared to healthy controls and analyze their improvement after surgery.

METHODS

Prospective case-control study of patients with primary hyperparathyroidism. The Beck questionnaire and Pittsburgh Sleep Quality Index were used. The control group consisted of healthy people matched by age and sex. Preoperative results were compared with results at 3 and 12 months after surgery and compared with the control group. Statistical analysis consisted of the Kolmogorov-Smirnov test and Student's t test for correlations.

RESULTS

Forty-nine patients who underwent parathyroidectomy were analyzed. In relation to depression, differences were observed between the results of the preoperative period and 3 months after surgery, with a significant decrease in depression score (16.80 ± 9.98 vs 13.08 ± 10.76; P = .001). This improvement was maintained after 1 year (P < .001). Regarding the quality of sleep, there were no differences 3 months after the intervention, but there were differences at 12 months (9.48 ± 4.76 vs 8.27 ± 4.38; P = .032). The dimensions of the Pittsburgh Sleep Quality Index were analyzed, observing significant differences only in daytime dysfunction after 3 months and 12 months after surgery (1.02 ± 0.99 vs 0.69 ± 0.82; P = .01 and 1.04 ± 0.98 vs 0.60 ± 0.76; P = .004).

CONCLUSION

Mood changes and sleep quality improve after primary hyperparathyroidism surgery, although at different postoperative times, with this improvement being more pronounced in mood. This assessment should be taken into account in the preoperative consultation of patients with primary hyperparathyroidism.

Attitude of the Older Population Toward Controlled Asystole Donation

INTRODUCTION

Studies about the knowledge of and attitude toward new lines of organ donation in a group of older people are important due to the increase in older organ donors.

OBJECTIVES

To analyze the attitude of citizens over 65 years of age in southeastern Spain toward controlled asystole donation (CAD) and to determine the psycho-social profile that influences this attitude.

METHODS

The study population consisted of citizens over 65 years of age. A representative sample was obtained in southeastern Spain (N = 420). A questionnaire about attitudes toward CAD was used, detailing in the questionnaire that this is a type of donation from people who have died of circulatory and respiratory criteria after the limitation of life support treatment. Several psychosocial variables were also taken into account. Statistical analysis included the χ2 test and multivariate analysis.

RESULTS

The completion rate was 84% (n = 351). Favorable attitude toward organ donation and transplantation (ODT) was 98% (n = 344) overall, and CAD was viewed favorably by 45% (n = 158). The psychosocial variables that influenced attitude toward CAD were mainly having received a talk about ODT (odds ratio [OR] 5.6), knowing the opinion of one's partner (OR 7.95), acceptance of cremation (OR 1.09), and acceptance of autopsy (OR 3.002).

CONCLUSIONS

The attitude of older people toward CAD is unfavorable despite a willingness to support ODT in general. This attitude is influenced by variables of social and family dialogue about ODT, attitude to body manipulation, and having received information about ODT.

The Influence of Hyperparathyroidism Patient Profile on Quality of Life After Parathyroidectomy

BACKGROUND

Improvements in quality of life (QoL) after parathyroidectomy in patients with primary hyperparathyroidism (PHPT) is discussed. It has not been analyzed whether these improvements can be influenced by a specific socio-personal or clinical patient profile.

OBJECTIVES

to analyze QoL differences after parathyroidectomy and to determine a socio-personal and clinical profile that influences improvement after parathyroidectomy.

METHODS

A longitudinal prospective cohort study in patients with PHPT. SF-36 and PHPQOL questionnaires were completed by the patients. A comparative preoperatory analysis was carried out, at three and twelve months after surgery. Student's t test was used for the correlations. The size of the effect was assessed using G*Power software. A multivariate analysis was performed to evaluate the socio-personal and clinical variables affecting the improvement in QoL after surgery.

RESULTS

Forty-eight patients were analyzed. Three months after surgery an improvement was found in physical function, general health, vitality, social function, emotional role, mental health and in the patient's declared health assessment. One year after the intervention a general improvement was observed, with a greater effect on mental health and declared health evolution. Patients with bone pain presented with a higher probability of improvement after surgery. Patients with prior psychological disease had a lower associated probability of an improvement and high levels of PTH related to a greater probability of improvement after surgery.

CONCLUSIONS

There is an improvement in the QoL of PHPT patients after parathyroidectomy. Patients with bone pain and high PTH levels prior to the parathyroidectomy present with a greater probability of having a greater improvement in QoL after surgery.
