Hypothyroidism After Using Superior Thyroid Artery as A Recipient Artery

The aim of this study was to evaluate whether the use of the superior thyroid artery (SThA) as a recipient vessel affect thyroid dysfunction in patients undergoing TPLE combined with hemithyroidectomy. Our study revealed there was no significant difference in the postoperative hypothyroidism between patients with SThA used and not. We suggest that even after hemithyroidectomy, with inferior thyroid arteries are preserved, the SThA can be used as a recipient vessel.


Objective

Superior thyroid artery (SThA) is a common recipient artery in free tissue transfer even after total pharyngolaryngoesophagectomy (TPLE) with hemithyroidectomy. The aim of this study was to evaluate whether the use of SThA as a recipient vessel affect thyroid function in patients undergoing TPLE with hemithyroidectomy.

Methods

From 2011 to 2020, 91 patients who underwent free jejunum transfer after TPLE with hemithyroidectomy were divided into two groups. In Group1 (n = 47), the contralateral SThA was used for the anastomosis. In Group2 (n = 44), other vessels were used. Retrospective chart review was performed comparing postoperative thyroid function between two groups.

Results

In group1, 17 patients presented hypothyroidism, 21 presented latent hypothyroidism and 9 presented no thyroid dysfunction comparing 15, 19, and 10 respectively in group 2. There were no significant differences between the two groups.

Conclusion

Even after hemithyroidectomy, with inferior thyroid arteries are preserved, the SThA can be used as a recipient vessel.

Proteomic analysis of infected root canals with apical periodontitis in patients with type 2 diabetes mellitus: a cross‐sectional study

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Aim

This study aimed to quantitatively and qualitatively determine the proteomic profile of apical periodontitis (AP) in Type 2 Diabetes Mellitus (T2DM) patients in comparison to systemically non-compromised patients, and to correlate the protein expression of both groups with their biological functions.

Methodology

The sample consisted of 18 patients with asymptomatic AP divided into two groups according to the presence of T2DM: diabetic group - patients with T2DM (n = 9) and control group - systemically healthy patients (n = 9). After sample collection, the root canal samples were prepared for proteomic analysis using reverse-phase liquid chromatography mass spectrometry. Label-free quantitative proteomic analysis was performed by Protein Lynx Global Service software. Differences in protein expression between groups were calculated using t-test (p < 0.05). Biological functions were analyzed using the Homo sapiens UniProt database.

Results

A total of 727 human proteins were identified in all samples. Among them, 124 proteins common to both groups were quantified, out of which 65 proteins from the diabetic group showed significant differences compared with the control: 43 up-regulated (p < 0.05) and 22 down-regulated (p < 0.05) proteins. No significant differences in protein expression were seen for the remaining 59 proteins (p > 0.05). Most proteins with differences in expression were related to immune/inflammatory response. Neutrophil gelatinase-associated lipocalin, Plastin-2, Lactotransferrin, and 13 isoforms of immunoglobulins were up-regulated. In contrast, Protein S100-A8, Protein S100-A9, Histone H2B, Neutrophil defensin 1, Neutrophil defensin 3, and Prolactin-inducible protein were down-regulated.

Conclusions

Quantitative differences were demonstrated in the expression of proteins common to diabetic and control groups, mainly related to immune response, oxidative stress, apoptosis, and proteolysis. These findings revealed biological pathways that provide the basis to support clinical findings on the relationship between AP and T2DM.

Comparison of transfusion reactions in children and adults: A systematic review and meta‐analysis

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

There are no international standards or normalizations for diagnosing and treating complications from blood transfusions. We comprehensively compared the incidence of adverse blood transfusions in children and adults.

Methods

Available literature on blood transfusion adverse reactions in children and adults prior to November 27, 2021 was collected from several electronic databases. This meta-analysis was performed using Revman 5.2 and Stata 15.1.

Results

The incidence of transfusion reactions is higher in children than in adults. Children transfused with red blood cells and platelets exhibited a higher incidence of transfusion reaction than that of adults. Moreover, the incidence of allergic and febrile non-hemolytic transfusion reactions was significantly higher in children than in adults. The incidence of some rare transfusion reactions was also significantly higher in children than in adults.

Conclusion

The incidence of transfusion reactions in children and adults is varied. Guidelines for children are necessary.

Safety and value of pre‐transplant antibiotic allergy delabeling in a quaternary transplant center

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Self-reported antibiotic allergies, also known as antibiotic allergy labels, are common and may lead to worse patient outcomes. Within immunocompromised patients, antibiotic allergy labels can lead to inappropriate use of antimicrobials and may limit options for prophylactic and therapeutic options in the post-transplant period. While antibiotic allergy delabeling is considered an important aspect of antibiotic stewardship protocols, evidence and awareness of its application in transplant recipients is limited.

Methods

We describe our experience with an antibiotic allergy delabeling intervention in the pre-transplant evaluation period and its impact on post-transplant antimicrobial utilization. This was a retrospective analysis of patients with an antibiotic allergy label who underwent evaluation for solid organ or stem cell transplantation between 2015–2020. Patients included in this analysis were those who completed pre-transplant antibiotic allergy delabeling through our Drug Allergy Clinic and were retained in care for six months after transplant.

Results

Twenty-six of 27 patients underwent pre-transplant antibiotic allergy delabeling and safely received the delabeled antibiotic post-transplant. There were no reported side effects to the delabeled antibiotic within 6 months post-transplant. Specific examination of sulfonamide (sulfa)-antibiotic delabeling showed cost savings of $254 to $2,910 per patient in the post-transplant period compared to the use of alternative antibiotics for prophylaxis protocol.

Conclusion

Antibiotic allergy delabeling prior to transplant is safe, is of high value, and should be considered in the pre-transplant evaluation period. More resources are needed for the development of delabeling guidelines and support for broad implementation of pre-transplant antibiotic allergy delabeling programs.

Differences in levothyroxine action on thyroid autoimmunity and hypothalamic–pituitary–thyroid axis activity between metformin- and myo-inositol-treated women with autoimmune subclinical hypothyroidism

The impact of levothyroxine on thyroid antibody titers, thyrotropin, free thyroxine and free triiodothyronine is more pronounced in women with autoimmune subclinical hypothyroidism receiving metformin than myo-inositol.


Abstract

What is known and objective

Insulin resistance impairs the impact of levothyroxine on thyroid autoimmunity and hypothalamic–pituitary–thyroid axis activity. Both metformin and myo-inositol were found to improve insulin sensitivity and to reduce thyrotropin levels in individuals with hypothyroidism. The aim of the present study was to compare the effect of levothyroxine on thyroid autoimmunity and hypothalamic–pituitary–thyroid axis activity between women receiving metformin and myo-inositol.

Methods

The study included two groups of women with autoimmune hypothyroidism, treated for at least 6 months with either metformin (group A; n = 25) or myo-inositol (group B; n = 25). Both groups were matched for age, insulin sensitivity, hormone levels and antibody titers. For the following 6 months, all women received levothyroxine. Plasma levels of glucose, insulin, thyrotropin, free thyroid hormones, prolactin, 25-hydroxyvitamin D and high-sensitivity C-reactive protein (hsCRP), as well as titers of thyroid peroxidase and thyroglobulin antibodies were assessed at the beginning and at the end of the study.

Results and discussion

At baseline there were not differences between the study groups. Although levothyroxine reduced thyrotropin levels, increased free thyroid hormone levels and decreased antibody titers in both study groups, these effects were more pronounced in group A than group B. Only in group A, levothyroxine increased 25-hydroxyvitamin D, decreased hsCRP and improved insulin sensitivity. The impact of levothyroxine on thyrotropin and free thyroid hormones correlated with treatment-induced changes in insulin sensitivity, antibody titers, 25-hydroxyvitamin D and hsCRP.

What is new and conclusion

The present study suggests that the impact of levothyroxine on thyroid autoimmunity and hypothalamic–pituitary–thyroid axis activity is stronger in women receiving metformin than in women treated with myo-inositol.
