Reference Intervals for Thyroid Hormones During the First Trimester of Gestation: A Report from an Area with a Sufficient Iodine Level.

A concern was raised 1 regarding the number of pregnant women in the analysis of reference range for the thyroid hormones in pregnancy 2, where we reported 185 cases and it was believed to be 145 cases.

Effect of lifestyle modification education based on health belief model in overweight/obese patients with non-alcoholic fatty liver disease: A parallel randomized controlled clinical trial.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common emerging liver disease worldwide. Lifestyle modification is the most emphasized method on management of this disease. METHODS: In order to conduct this parallel, randomized controlled trial study, eighty-two NAFLD patients recruited and allocated to intervention group or the control. RESULTS: After two months of intervention, significant improvements in all health belief model (HBM) variables and knowledge were seen within the intervention group (p < 0.001) and also the improvements were significantly superior between two groups (p < 0.001). Furthermore, prominent significant reduction for liver enzyme was observed in the intervention group compared to the controls. Similarly, ultra-sonographic findings revealed a significant improvement in the intervention group versus control. CONCLUSIONS: This HBM-based lifestyle modification education could be effective not only in the HBM domains but also in the improvement of NAFLD parameters. Therefore, it could be useful to use this educational program for NAFLD patients in order to impact on their beliefs and body together.

Thyroid volume and nodular and diffuse thyroid diseases by ultrasonography in pregnant women: A case-control study.

BACKGROUND: Currently, it is shown that pregnancy may have an impact on the thyroid that can be leading to pregnancy complications such as abortion, preeclampsia, and preterm delivery. The objective was to compare the thyroid volume, number and characteristics of thyroid nodules, and prevalence of diffuse thyroid diseases in a sample of Iranian pregnant women in the first trimester to nonpregnant women. MATERIALS AND METHODS: This case-control study was conducted on 298 pregnant and 290 nonpregnant women. Thyroid volume, maximum diameter of thyroid nodules and prevalence of moderate to highly suspicious thyroid nodules, Hashimoto's appearance and goiter were assessed using thyroid ultrasonography. Antithyroperoxidase (TPO) antibodies were measured if the sonographic features were highly suggested for Hashimoto's thyroiditis. RESULTS: The mean of total thyroid volume in pregnant and nonpregnant women was 6 and 6.5 ml, respectively (P = 0.053), and the median (interquartile range) was 6.2 and 5.5, respectively. Nodules were observed in 16.4% of pregnant and 16.6% of nonpregnant women (P = 0.845). Hashimoto's thyroiditis was detected in 6.7% of pregnant and 12.4% of nonpregnant women (P = 0.013). Anti-TPO antibodies were detected in 5% of pregnant and 9.3% of nonpregnant women (P = 0.034). CONCLUSION: The thyroid volume and nodule characteristics in the first trimester of pregnancy were similar to nonpregnant women. Hashimoto's thyroiditis and anti-TPO antibodies in pregnant women were significantly lower than in nonpregnant women.

Reference Intervals for Thyroid Hormones During the First Trimester of Gestation: A Report from an Area with a Sufficient Iodine Level.

The physiological changes during pregnancy modulate the endocrine system. Therefore, both the American and the European thyroid associations recommend the use of local trimester-specific reference intervals. The purpose of this study was to establish the first trimester reference intervals for thyroid function tests in the central area of Iran. We examined 436 pregnant women in their first trimester of pregnancy, and 444 non-pregnant women in a cross sectional study. Serum levels of thyroid stimulating hormone (TSH), free thyroxin (FT4), free triiodothyronine (FT3), thyroid peroxidase antibody, urinary iodine concentration (UIC), and thyroid volume were measured for all subjects. The first trimester-specific reference intervals (2.5th-97.5th percentile) were determined for 185 pregnant women and 256 non-pregnant women with negative TPOAb, adequate iodine level (UIC≥150 µg/l in pregnant and UIC≥100 µg/l in non-pregnant women), and normal thyroid examination. We calculated multiples of the median (MoM) for TFTs to normalize the obtained data. The first trimester-specific reference intervals of serum TSH, FT4, and FT3 for pregnant women were 0.20-4.60 mIU/l, 9.0-18.02 pmol/l, and 3.40-5.64 pmol/l, respectively, while the corresponding figures for non-pregnant women were 0.59-5.60 mIU/l, 9.52-19.30 pmol/l, and 3.70-5.55 pmol/l, respectively. The first and 99th percentile MoM of TSH in pregnant women in their first-trimester was 0.06-4.62. The local normal reference ranges for the first trimester of pregnancy in central region of Iran were different from the ranges suggested by the ATA.

The efficacy of topical royal jelly on healing of diabetic foot ulcers: a double-blind placebo-controlled clinical trial.

Foot ulcers are major sources of morbidity in individuals with diabetes mellitus. As royal jelly (RJ, a worker honey bee product) contains enzymatic, antibacterial and vasodilative properties, it can potentially help in healing of diabetic foot ulcers (DFUs). This study aimed to evaluate the efficacy of topical RJ on healing of DFUs. Diabetic patients with foot ulcers who were referred to us at Khorshid Hospital, Isfahan, Iran, were managed by offloading, infection control, vascular improvement and debridement (if required). Then, all ulcers were randomly selected to receive either 5% sterile topical RJ or placebo on their total surface area. Patients were followed for 3 months or until complete healing. Twenty-five patients (6 females and 19 males) and a total of 64 ulcers were included and randomly allocated to case or control group (32 per group). Four ulcers were excluded and 60 ulcers included in the final analysis. Healing parameters including depth, length and width reduction rate, duration of complete healing and incidence of complete healing did not show any significant difference (P = 0·69, 0·95, 0·7, 0·74 and 0·6, respectively) between groups. We did not observe any side effect of topical RJ application. This study could not confirm any significant superiority of 5% topical RJ over placebo for the treatment of DFUs.

The efficacy of topical Royal Jelly on diabetic foot ulcers healing: A case series.

BACKGROUND: Foot ulcers and infections are the major sources of morbidity in individuals with diabetes mellitus. This study aimed to evaluate the efficacy of topical Royal Jelly (a worker honey bee product) on healing diabetic foot ulcers. METHODS: Diabetic patients with foot ulcers that were referred to our clinic at Khorshid Hospital, Isfahan, Iran; were evaluated three times a week and treated according to standard treatments consisted of offloading, infection control, vascular improvement and debridement if required. In addition, all ulcers were measured and then topical sterile 5% Royal Jelly was applied on the total surface area of the wounds. Eventually, they were covered with sterile dressings. Each patient was followed for a period of three months or until the complete healing. RESULTS: A total of eight patients were enrolled in this study. Of these, two had two ulcers and, therefore, ten ulcers were evaluated. Two ulcers were excluded. Seven of the remained eight ulcers healed. Mean duration of complete healing was 41 days. One ulcer did not completely heal but improved to 40% smaller in length, 32% in width and 28% in depth. The mean length, width and depth reduction rates were 0.35 mm/day, 0.28 mm/day and 0.11 mm/day, respectively. CONCLUSIONS: Royal Jelly dressing may be an effective method for treating diabetic foot ulcers besides standard treatments.
