Evaluation of fetal diaphragm excursion and thickness in term pregnancies complicated with pre-gestational and gestational diabetes mellitus

Background

Both pre-gestational (PGDM) and gestational diabetes mellitus (GDM) make pregnancy complicated. Moreover in the literature GDM and PGDM have been held responsible for respiratory morbidity in newborns. Diaphragm ultrasound (DUS) is a valuable and noninvasive method that provides an opportunity to examine the diaphragmatic morphology and function. This study examined the quality of fetal diaphragmatic contractions in pregnant women complicated with GDM and PGDM.

Methods

A total of 105 volunteers who were separated into three groups; (1) A GDM group (n = 35), (2) a PGDM group (n = 35), and (3) a healthy non-diabetic control group (n = 35). All volunteers with the cephalic presentation and only male fetuses were examined in the 37th week of gestation. This cross sectional and case controlled study was performed at the perinatology clinic of the Erciyes University School of Medicine between 15.01.2020 and 01.08.2021. The thickness of fetal diaphragm (DT), diaphragmatic excursion (DE), diaphragm thickening fraction (DTF) and costodiaphragmatic angle (CDA) was measured and recorded by ultrasound and examined on the video frame during the inspiration and expiration phases of respiration.

Results

Especially the PGDM group represented adversely affected diaphragm function parameters. DT inspiration, DT expiration, DE, CDA inspiration and DTF values were significantly different between PGDM and the control group. Neonatal intensive care unit (NICU) admission was high among babies who were born to pregnancies complicated with PGDM or GDM.

Conclusions

The quality of fetal diaphragm movements is affected in pregnancies complicated with GDM and PGDM. The prolonged duration of diabetes may have additional adverse effects on diaphragm morphology and its function.

The percentage of pre-gestational diabetes mellitus (PGDM) in pregnancy is 13–21% and the remaining part of diabetes is gestational diabetes mellitus (GDM). Both of the complications are related to respiratory problems at birth.

Until now, it was known that this situation was due to the lack of surfactant, which has a facilitating effect on the participation of the lungs in respiration. However, in this study, the diaphragm of the babies of patients with PGDM and GDM was examined. The thickness of fetal diaphragm, movements and function were evaluated via using ultrasound. As a result, it was determined that the diaphragm movements were impaired and the babies born from these patients needed more pediatric care.

This study will open horizon on new studies examining the functional capacity of the diaphragm in the future. In the future, it may be possible to decide which baby will need intensive care by examining the diaphragm.

Comparison of spironolactone and spironolactone plus metformin in the treatment of polycystic ovary syndrome

The aim of this study was to evaluate and compare the effects of spironolactone and spironolactone plus metformin treatments on body mass index (BMI), hirsutism score, hormone levels, and insulin resistance in women with polycystic ovary syndrome (PCOS). Thirty-seven patients with PCOS were randomly assigned to receive spironolactone 100 mg/d (spironolactone group, 18 patients) or spironolactone 100 mg/d plus metformin 2000 mg/d (combination group, 19 patients) for 12 months. BMI, modified Ferriman-Gallway score (FGS), serum levels of regarding hormones, and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed before and after the treatments. Six patients in the spironolactone group and four patients in the combination group reported inter-menstrual vaginal bleeding during treatments. In hirsutism scores, the spironolactone therapy resulted in 25.2% reduction, while combination therapy resulted in 28.3% reduction (p > 0.05, between groups). When the groups were compared in terms of percent changes in BMI, FGS, HOMA-IR, and hormone values other than free testosterone, no significant difference was noted. In the present study, FGSs were significantly decreased in both groups; however, combination therapy was not more effective than spironolactone alone in terms of BMI, FGS, hormone levels, or insulin resistance.

Assessment of Macular Peripapillary Nerve Fiber Layer and Choroidal Thickness Changes in Pregnant Women with Gestational Diabetes Mellitus, Healthy Pregnant Women, and Healthy Non-Pregnant Women

Background

Gestational diabetes mellitus (GDM) is a risk factor for the development of type II diabetes and it causes maternal and child morbidity. Screening for diabetic retinopathy (DR) is important because patients who develop DR have no symptoms until macular edema and/or proliferative diabetic retinopathy (PDR) are already present. The aim of this study was to determine the early retinal findings of GDM.

Material/Methods

This study was conducted in a tertiary research center. We conducted a prospective cross-sectional study with 3 groups: Group 1 consisted of 36 pregnant women with GDM, Group 2 consisted of 24 healthy pregnant women, and Group 3 consisted of 38 healthy non-pregnant women of reproductive age. Spectralis optical coherence tomography (OCT) was used for the assessment. Macular, choroid, and retinal nerve fiber layer (RNFL) thicknesses were evaluated in patients with GDM and comparisons were made among pregnant women with GDM, healthy pregnant women, and healthy non-pregnant women for these parameters.

Results

The nasal part of the RNFL was significantly thinner in the GDM group than in the healthy pregnant group. None of the patients had retinopathy or macular edema at the time of examination.

Conclusions

Decreased nasal part of RNFL thickness may be the first retinal change in patients with GDM. Our study suggests that OCT should be performed for the patients with GDM for detection of early retinal changes associated with GDM.

Lack of any association between season of diagnosis and survival of gastric cancer cases in Kayseri, Turkey

BACKGROUND

The influence of season of diagnosis on cancer survival has been an interesting issue for many years. Most studies have shown a possible association between seasonality and survival in some cancers. We aimed to investigate whether there is an association between season of diagnosis and survival in patients with gastric cancer.

MATERIALS AND METHODS

We reviewed retrospectively the files of 279 histologically proven gastric cancer patients. According to diagnosis date, the patients were grouped into 4 seasons of diagnosis groups, spring, summer, autumn, and winter.

RESULTS

There was no significant differences when the overall survival rates of the patients were compared according to the patients' season of diagnosis (p: 0.871). Median overall survival rates were 22.0 (14.5-29.5) months for the patients who were diagnosed in spring, 24.0 (12.4-35.6) for summer, 18.0 (9.96-26.0) for autumn and 21.0 (16.3-25.7) for winter. Median disease-free survival rates were 66.0 (44.1-68.1) months for the patients who were diagnosed in spring, 28.0 (17.0-39.0) for summer, 22.0 (0-46.4) for autumn and 23.0 (17.5-28.5) for winter. While the rate was best for the patients diagnosed in spring the differences were not statistically significant (p= 0.382).

CONCLUSIONS

On the basis of the above results the season was not suggested as contributing to prognosis in gastric cancer cases in Kayseri, Turkey.

Routine screening for Cushing's syndrome is not required in patients presenting with hirsutism

CONTEXT

Prevalence of Cushing's syndrome (CS) in patients presenting with hirsutism is not well known.

OBJECTIVE

Screening of CS in patients with hirsutism.

SETTING

Referral hospital.

PATIENTS AND OTHER PARTICIPANTS

This study was carried out on 105 patients who were admitted to the Endocrinology Department with the complaint of hirsutism.

INTERVENTION

All the patients were evaluated with low-dose dexamethasone suppression test (LDDST) for CS.

MAIN OUTCOME MEASURE

Response to LDDST in patients presenting with hirsutism.

RESULTS

All the patients had suppressed cortisol levels following low-dose dexamethasone administration excluding CS. The etiology of hirsutism was polycystic ovary syndrome in 79%, idiopathic hirsutism in 13%, idiopathic hyperandrogenemia in 6%, and nonclassical congenital hyperplasia in 2% of the patients.

CONCLUSION

Routine screening for CS in patients with a referral diagnosis of hirsutism is not required. For the time being, diagnostic tests for CS in hirsute patients should be limited to patients who have accompanying clinical stigmata of hypercortisolism.
