Incretin levels in patients with hypothyroidism and the evaluation of incretin levels alterations with treatment

Publié en ligne: 19 Dec 2019
Pages: 3 - 9

Résumé

AbstractBackground

Incretin hormones may influence the effects of thyroid hormones on insulin secretion, insulin resistance, and glucose metabolism. Thyroid hormones regulate insulin secretion, and the risk of diabetes was found to be associated with thyroid hormones.

Objectives

To determine whether incretin hormones influence the effects of thyroid hormones on insulin resistance and glucose metabolism.

Methods

A total of 26 patients were included in 2 groups consisting of 13 patients with hypothyroidism and 13 healthy controls. Levels of glucose, insulin, glucagon-like peptide 1 (GLP-1), and gastric inhibitory polypeptide (GIP) levels were measured in 0, 30, 60, 90, and 120th min during the oral glucose tolerance test in the control group and before and after thyroxine treatment in the hypothyroid group.

Results

In the hypothyroid group, waist circumference decreased after the euthyroid state was achieved (P = 0.026). No statistically significant differences were detected in the GLP-1 and GIP levels at baseline and 30, 60, 90, and 120 min between the hypothyroidism and control groups or after ensuring the euthyroid state in patients with hypothyroidism. Peak GLP-1 levels were observed at 30 min in the control group, whereas peak GLP-1 and GIP levels were detected at 90 min in the hypothyroidism group. After achieving the euthyroid state, peak GLP-1 and GIP levels were detected at 30 min as well.

Conclusion

In patients with hypothyroidism, the incretin hormones, especially the peak response of the incretin system, are significantly affected. Significant changes were observed in the incretin system by correcting hypothyroidism.

Clinical subtypes of breast cancer in Thai women: a population-based study of Chiang Mai province

Publié en ligne: 19 Dec 2019
Pages: 11 - 17

Résumé

AbstractBackground

The change over time of distribution of breast cancer subtypes using population-based data has not been reported.

Objective

To describe the change over time of the distribution of female breast cancer by clinical subtype among the population in Chiang Mai, Thailand.

Methods

Data of breast cancer patients from Chiang Mai Cancer Registry, diagnosed from 2004 to 2013 were combined with immunohistochemical status from medical record, and used to describe the proportions of clinical breast cancer subtypes: (1) luminal A-like (ER+/PR+ and HER2-), (2) luminal B-like (ER+/PR+ and HER2+), (3) HER2 (ER- and PR- and HER2+), (4) triple-negative (ER- and PR- and HER2-). The distribution of breast cancer subtypes by age group was also described.

Results

Among 3,228 female breast cancer cases diagnosed during 2004–2013, the median age was 52 years and most patients presented at the regional stage. The unknown tumor subtype was lower than 25% in the periods 2008– 2009, 2010–2011, and 2012–2013. In those periods, the proportions of luminal A-like were 33%, 36%, and 48%; the proportions of luminal B-like were 14%, 20%, and 16%, the proportions of HER2 were 15%, 14%, and 13%; and the proportions of triple-negative were 16%, 14%, and 13%, respectively. In comparison with other groups, women aged ≥60 years had a significantly higher proportion of luminal A-like (P = 0.001), while women aged <40 years tended to have a higher proportion of triple-negative (P = 0.10).

Conclusions

The proportion of breast cancer with luminal subtypes is increasing. Thus, in the future, treatment protocols with a variety of hormone therapies should be provided in order to improve efficacy and coverage of treatment for this population.

Pathways to parental anxiety: effect of coping strategies for disruptive behaviors in children with attention deficit-hyperactivity disorder

Publié en ligne: 19 Dec 2019
Pages: 19 - 25

Résumé

AbstractBackground

Disruptive behaviors are commonly found in children with attention deficit-hyperactivity disorder (ADHD) and affect the mental health of parents. However, a study of the direct and indirect effects between disruptive behaviors in children with ADHD and parental anxiety and coping strategies is apparently lacking.

Objective

To examine the direct and indirect relationship between disruptive behaviors in children with ADHD and parental anxiety and coping strategies as a mediator.

Method

A cross-sectional study was conducted at King Chulalongkorn Memorial Hospital, Thailand between March 2015 and January 2016. Participants comprised 200 parents whose children were diagnosed with ADHD by physicians. Participants completed questionnaires regarding sociodemographic characteristics including The Thai Hospital Anxiety and Depression Scale, The Swanson, Nolan and Pelham (SNAP-IV): parent form (Thai version), and The Coping Scale Questionnaire (Thai version).

Results

The direct path between disruptive behaviors and anxiety was significant (b = 0.21, P = 0.002). Moreover, a significant indirect path was found between disruptive behaviors and coping behavior with escape–avoidance (β = 0.20, P = 0.005), and an indirect path was found between escape–avoidance and anxiety (b = 0.31, P <0.001).

Conclusions

Health care professionals should evaluate the use of coping strategies by parents of children with ADHD and encourage the parents to use a positive strategy for coping with the disruptive behaviors of their children.

Survival outcomes of low-risk and intermediate-risk stage IB1 cervical cancer patients

Publié en ligne: 19 Dec 2019
Pages: 27 - 32

Résumé

AbstractBackground

Survival for patients with early stage cervical cancer without any high-risk factors treated with radical hysterectomy is excellent. However, there are few data on the survival outcomes for low-risk and intermediate-risk early stage cervical cancer patients.

Objective

To determine survival outcomes and prognostic factors of low-risk and intermediate-risk stage IB1 cervical cancer patients.

Methods

Stage IB1 cervical cancer patients with radical hysterectomy and pelvic lymphadenectomy were retrospectively reviewed. Patients with positive pelvic nodes, parametrial involvement, and positive margin who are classified as high-risk patients were excluded. Patients with squamous cell carcinoma or grade 1–2 adenocarcinoma, tumor size less than 2 cm, no lymphovascular space invasion (LVSI), and depth of stromal invasion (DSI) less than 10 mm were defined as low-risk patients. Survival was evaluated using the Kaplan–Meier method and compared by the log-rank test. Multivariate analysis was performed using Cox proportional-hazards regression.

Results

There were 82 (42.3%) low-risk patients and 112 (57.7%) intermediate-risk patients. More patients in intermediate risk received adjuvant treatment (3.6% and 14.3%, P = 0.07). Three (3.6%) low-risk patients and 18 (16.1%) intermediate-risk patients had recurrent disease (P = 0.004). At median follow-up of 86 months, 1.2% of low-risk patients and 8.9% of intermediate-risk had cancer-related deaths (P = 0.02). Low-risk patients had significantly better 5-year disease-free survival (98.2% vs 91.1%, P = 0.01) and estimated 5-year overall survival (98.5% vs 91.1%, P = 0.01). DSI more than 10 mm and presence of LVSI were significantly associated with recurrence. However, LVSI was an independent prognostic factor.

Conclusion

Stage IB1 cervical cancer patients had excellent survival. Low-risk patients had significantly better survival. Presence of LVSI was an independent prognostic factor.

A somatic PIK3CA p.H1047L mutation in a Thai patient with isolated macrodactyly: a case report

Publié en ligne: 19 Dec 2019
Pages: 33 - 36

Résumé

AbstractBackground

Macrodactyly is a rare congenital deformity characterized by gigantism of all structures of the digits. Previous reports showed that the mosaic PIK3CA variants were associated with overgrowth syndromes including macrodactyly.

Objectives

To determine the genetic alteration in a Thai patient with enlarged soft tissue of the left middle and left fourth fingers with abnormal enlarged phalanges.

Method

A nerve and a skin piece were separated from a therapeutically surgically removed part of the enlarged digit. Skin fibroblasts were cultured from the removed skin piece. DNA was isolated from the nerve tissue, cultured skin fibroblasts, and peripheral blood leukocytes. Polymerase chain reaction (PCR) followed by Sanger sequencing of PIK3CA was performed.

Results

Mutation analysis revealed the c.3140A>T (p.(H1047L)) variant of PIK3CA in the nerve tissue and the cultured dermal fibroblasts but not in leukocytes from the peripheral blood.

Conclusion

The somatic c.3140A>T (p.(H1047L)) variant of PIK3CA was found in a Thai patient with isolated macrodactyly, the same as those previously identified in other populations.
