Predictors of prenatal distress and fear of childbirth among nulliparous and parous women

Background

Prenatal distress and fear of childbirth negatively affect the health of the mother and the fetus. Sociodemographic and pregnancy related characteristics may influence prenatal distress and fear of childbirth.

Aim

This study aimed to explore the relationship between fear of childbirth and prenatal distress levels with accompanying factors.

Subjects and Methods

The study was designed as a cross-sectional survey study and conducted in the outpatient clinic of Obstetrics and Gynecology Department of Pamukkale University Hospital, Denizli, Turkey, between April 2017 and January 2018. Survey data were collected from 103 third-trimester pregnant women who had admitted to the hospital for routine prenatal examination. Sociodemographic Information Form, the Revised Prenatal Distress Questionnaire (NUPDQ), and the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) were used to collect data. Sociodemographics, obstetrics, and other variables were summarized by descriptive statistics. Mann-Whitney U-test, Chi-squared test, and Fisher's exact test were used for comparison of data between groups.

Results

The mean score of NUPDQ was 7.58 (SD 4.09) in the nulliparous group and 8.17 (SD 5.16) in the multiparous group (P = 0.68). The mean W-DEQ score was 40.46 (SD 21.80) in nulliparous women and 45.55 (SD 26.72) in multiparous women (P = 0.38). The W-DEQ and NUPDQ scores were moderately correlated with a Spearman correlation co-efficient of 0.58 (P < 0.001).

Conclusions

The results of this study revealed that fear of childbirth and prenatal distress were moderately and positively correlated. NUPDQ and W-DEQ can be used during pregnancy to understand if pregnant women have fear or distress. This could help to give a better support to pregnant women.

Comparison of intracompartmental pressures in a rabbit model of open and closed tibial fractures

We compared the intracompartmental pressures (ICPs) of open and closed tibial fractures with the same injury pattern in a rabbit model. In all, 20 six-month-old New Zealand White male rabbits were used. They were randomised into two equal groups of ten rabbits; an open fracture group (group 1) and a closed fracture group (group 2). Each anaesthetised rabbit was subjected to a standardised fracture of the proximal half of the right tibia using a custom-made device. In order to create a grade II open fracture in group 1, a 10 mm segment of fascia and periosteum was excised. The ICP in the anterior compartment was monitored at six-hourly intervals for 48 hours. Although there was a statistically significant difference in ICP values within each group (both p < 0.001), there was no significant difference between the groups for all measurements (all p ≥ 0.089). In addition, in both groups there was a statistically significant increase in ICP within the first 24 hours, whereas there was a statistically significant decrease within the second 24 hours (p < 0.001 for both groups). We conclude that open tibial fractures should be monitored for the development of acute compartment syndrome to the same extent as closed fractures.

Total antioxidant capacity, total oxidant status and oxidative stress index in the men exposed to 1.5 T static magnetic field

The aim of this study was to investigate the effects of a high-strength magnetic field produced by a magnetic resonance imaging (MRI) apparatus on oxidative stress. The effects of a 1.5 T static magnetic field on the total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) in male subjects were investigated. In this study, 33 male volunteers were exposed to a 1.5 T static magnetic field for a short time and the TAC, TOS and OSI of each subject were determined. Magnetic field exposure was provided using a magnetic resonance apparatus; radiofrequency was not applied. Blood samples were taken from subjects and TAC, TOS and OSI values were measured using the methods of Erel. TAC showed a significant increase in post-exposures compared to pre-exposures to the magnetic field (p < 0.05). OSI and TOS showed a significant decrease in post-exposures compared to pre-exposures to a 1.5 T magnetic field (for each of two, p < 0.01). The 1.5 T static magnetic field used in the MRI apparatus did not yield a negative effect; on the contrary, it produced the positive effect of decreasing oxidative stress in men following short-term exposure.

Contribution of genetic polymorphism in the renin-angiotensin system to the development of renal complications in insulin-dependent diabetes: Genetique de la Nephropathie Diabetique (GENEDIAB) study group

Diabetic nephropathy is a glomerular disease due to uncontrolled diabetes and genetic factors. It can be caused by glomerular hypertension produced by capillary vasodilation, due to diabetes, against constitutional glomerular resistance. As angiotensin II increases glomerular pressure, we studied the relationship between genetic polymorphisms in the renin-angiotensin system-angiotensin I converting enzyme (ACE), angiotensinogen (AGT), and angiotensin II, subtype 1, receptor-and the renal involvement of insulin-dependent diabetic subjects with proliferative retinopathy: those exposed to the risk of nephropathy due to diabetes. Of 494 subjects recruited in 17 centers in France and Belgium (GENEDIAB Study), 157 (32%) had no nephropathy, 104 (21%) incipient (microalbuminuria), 126 (25 %) established (proteinuria), and 107 (22%) advanced (plasma creatinine > or = 150 micromol/liter or renal replacement therapy) nephropathy. The severity of renal involvement was associated with ACE insertion/deletion (I/D) polymorphism: chi2 for trend 5.135, P = 0.023; adjusted odds ratio attributable to the D allele 1.889 (95% CI 1.209-2.952, P = 0.0052). Renal involvement was not directly linked to other polymorphisms. However, ACE I-D and AGT M235T polymorphisms interacted significantly (P = 0.0166): in subjects with ACE ID and DD genotypes, renal involvement increased from the AGT MM to TT genotypes. Thus, genetic determinants that affect renal angiotensin II and kinin productions are risk factors for the progression of glomerular disease in uncontrolled insulin-dependent diabetic patients.

[Adrenal histoplasmosis in a non-insulin-dependent diabetic patient]

Adrenal histoplasmosis is a rare infection that can be misdiagnosed as tuberculosis. We present here a case of adrenal histoplasmosis in a 65 year-old male diabetic with marked weight loss. Laboratory investigations noticed an inflammatory syndrome and the abdominal computed tomography scanner reported an heterogenous left adrenal mass of 6 cm in diameter. Hormonal as well as bacteriological studies were negative. The patient was operated and the histopathological examination proved that the mass was a tuberculoma and an anti-tuberculous treatment was started. Four months later, the patient suffered from recurrence of symptoms and laboratory investigations confirmed the inflammatory syndrome and the abdominal computed tomography scanner showed a right adrenal mass. A surgical biopsy was performed and specific fungal researches proved that the lesion was due to Histoplasma capsulatum. The patient experienced a remarkable improvement under anti-fungal treatment.
