ASTHMAXcel PRO patient satisfaction and usability field testing.

Background: ASTHMAXcel PRO, an enhanced version of the ASTHMAXcel mobile application, has been developed to deliver comprehensive, guideline-based asthma education while also facilitating the collection of patient-reported outcomes (PROs) and enhancing user experience.Objective: To perform field testing and conduct formative and summative evaluation of the ASTHMAXcel PRO application to assess its impact on patient satisfaction, usability, and usage.Methods: Twenty-eight adult patients completed a baseline visit during which ASTHMAXcel PRO was introduced, health literacy was assessed, and demographic data were collected. They were instructed to use the app for 4 weeks. The Questionnaire for User Interface Satisfaction (QUIS) and the Unified Theory of Acceptance and Use of Technology (UTAUT) questionnaire were administered at baseline and 4 weeks to assess user satisfaction and technology acceptance, respectively. Semi-structured interviews were conducted to gather feedback regarding the application from patients.Results: The baseline total scores were high for both UTAUT and QUIS (mean (SD): 64.2 (10.1), 6.8 (2.2) respectively) indicating that user satisfaction and acceptance began at high levels. UTAUT total score, as well as all domain scores, improved significantly from baseline to 4 weeks (p < 0.02). QUIS total score along with several domain scores (screen, system capabilities, usability) also increased from baseline to 4-weeks (p = 0.03, 0.01, 0.03, 0.01, respectively). These improvements remained significant when adjusting for age, gender, education, and health literacy. Patients reported that the application was helpful, informative, and easy to understand and use.Conclusion: The significant increases in satisfaction and technology adoption observed among ASTHMAXcel PRO users demonstrate that the application is viable and has the potential to improve upon usability challenges faced by existing mobile health applications.

Developing and evaluating ASTHMAXcel adventures: A novel gamified mobile application for pediatric patients with asthma.

BACKGROUND: The ASTHMAXcel mobile application has been linked to favorable outcomes among adult patients with asthma. OBJECTIVE: To assess the impact of ASTHMAXcel Adventures, a gamified, guideline-based, pediatric version on asthma control, knowledge, health care utilization, and patient satisfaction. METHODS: Pediatric patients with asthma received the ASTHMAXcel Adventures mobile intervention on-site only at baseline (visit 1), 4 months (visit 2), and 6 months (visit 3). The asthma control test, asthma illness representation scale-self-administered, pediatric asthma impact survey, and Client Satisfaction Questionnaire-8 were used to assess asthma control, knowledge, and patient satisfaction. Patients reported the number of asthma-related emergency department (ED) visits, hospitalizations, and oral prednisone use. RESULTS: A total of 39 patients completed the study. The proportion of controlled asthma increased from visit 1 to visits 2 and 3 (30.8% vs 53.9%, P = .04; 30.8% vs 59.0%, P = .02), and largely seen in boys. The mean asthma illness representation scale-self-administered scores increased from baseline pre- to postintervention, with sustained improvements at visits 2 and 3 (3.55 vs 3.76, P < .001; 3.55 vs 3.80, P = .001; 3.55 vs 3.99, P < .001). The pediatric asthma impact survey scores improved from baseline to visits 2 and 3 (43.33 vs 34.08, P < .001; 43.33 vs 31.74, P < .001). ED visits and prednisone use significantly decreased from baseline to visits 2 and 3 (ED: 0.46 vs 0.13, P = .03; 0.46 vs 0.02, P = .02; prednisone use, 0.49 vs 0.13, P = .02; 0.49 vs 0.03, P = .003. Satisfaction was high with mean client satisfaction questionnaire score of approximately 30 (out of 32) at all visits. CONCLUSION: ASTHMAXcel Adventures improved asthma control, knowledge, and quality of life, and reduced ED visits and prednisone use with high satisfaction scores.

Obstetric outcomes of patients with abortus imminens in the first trimester.

PURPOSE: We aimed to find out the effect of abortus imminens (AI) on obstetric outcomes of pregnancies which continued beyond the 24th week of gestation. METHODS: In this prospective study, 309 patients with AI were divided into high-risk group (with a risk factor for spontaneous abortus) (n = 92) and low-risk group (without a risk factor) (n = 217). The control group (n = 308) was chosen randomly. RESULTS: In AI group, preterm delivery, preterm premature rupture of membranes (PPROM), cesarean section (C/S) delivery, postpartum uterine atony and need of a neonatal intensive care unit (NICU) rates were significantly higher than control group. Gestational diabetes mellitus, PPROM, still birth, low APGAR scores were seen more frequently in the high-risk patients than in the control group. Furthermore in the high-risk group, preterm delivery, malpresentation, C/S delivery and need of NICU were increased much more than in the low-risk group. Gestational hypertension/preeclampsia, oligo/polyhydramniosis, intrauterine growth retardation, placenta previa, abruption of placenta, chorioamnionitis, congenital abnormalities, delivery induction, cephalopelvic disproportion, fetal distress and manual removal of placenta were not different among the groups. CONCLUSIONS: Patients with AI history, especially with high-risk factors can have adverse obstetric and neonatal results. So their antenatal follow-up has to be done cautiously for the early signs and symptoms of these complications.

The effect of hesperetin on ischemia-reperfusion injury in rat ovary.

PURPOSE: Hesperidin (HES), a citrus fruit extract, has beneficial effects on various ischemia/reperfusion (I/R) models. We aimed to evaluate the possible positive effects of hesperetin (HPT), an active metabolite of HES, on a rat ovarian I/R model. METHODS: We divided 24 Wistar Albino rats into four groups. Group I (n = 6) was sham operated, Group II (n = 6) was the I/R group, Group III (n = 6) was the I/R + solvent group and Group IV (n = 6) was the I/R + HPT group. Three hours of ischemia and 3 h of reperfusion were performed on each rat in Groups II, III, and IV. Dimethyl sulfoxide (DMSO) was given intraperitoneally to the rats in the III. Group, and 50 mg/kg of HPT dissolved in DMSO was given intraperitoneally to the rats in the IV. Group 30 min before reperfusion. After 3 h of reperfusion, the ipsilateral ovaries of the rats were examined immunohistochemically to detect apoptosis. RESULTS: Hematoxylin and eosin (H and E) staining demonstrated less edema and hemorrhage in the group where HPT was applied. Caspase-3 and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining showed significantly lower apoptosis in the group where HPT was used when compared to either the I/R or solvent group. CONCLUSIONS: To the best of our knowledge, this is the first study that shows the beneficial effects of HPT in an ovarian I/R injury. HPT improved tissue damage and apoptosis caused by I/R injury. To identify the possible positive effects of HPT in ovarian torsion of humans and use in clinical practice, more studies must be performed.

Maternal and fetal leptin and ghrelin levels: relationship with fetal growth.

PURPOSE: In our study, we investigated the influence of plasma levels ghrelin, leptin and other metabolic hormones (ILGF-1 and ILGF-2) in pregnants in regulating fetal body weight and mode of delivery. METHODS: A total of 36 appropriately healthy pregnants 19-36-year-old were involved in the study. Demographic characteristics, serum ghrelin, leptin, IGF-1 and IGF-2 levels of the pregnants were studied. RESULTS: Plasma ghrelin and leptin levels did not differ significantly among trimesters and delivery, in contrast to IGF-I and IGF-II concentrations were significantly higher in the first half of the pregnancy (P < 0.05). Serum leptin was significantly associated with mode of delivery (r = 0.231; P = 0.008), BMI (r = 0.462; P = 0.004). CONCLUSION: Metabolic factors are associated with fetal growth, but in AGA babies, there were no differences between any parameter and clinical factor.

Assessment of pulmonary functions and anthropometric measurements in women with polycystic ovary syndrome.

OBJECTIVES: The aims of this study were to compare pulmonary function tests of patients with polycystic ovary syndrome (PCOS) versus healthy women, and to investigate correlations between pulmonary function tests and anthropometric measurements of them. MATERIALS AND METHODS: A total of 31 women with PCOS and 29 controls matched for age and body mass index (BMI) were enrolled into the study. Pulmonary function tests were performed with spirometer. Body fat percentage was calculated from the skinfold thicknesses using the formula. Biacromial, chest antero-posterior and lateral diameter measurements were carried out with anthropometric set. RESULTS: There were no significant differences between patients with PCOS and healthy controls in the pulmonary function tests, body fat %, chest and abdomen region anthropometric measurements. There were moderate negative correlations only between forced expiratory volume per 1 s and BMI, abdomen circumference, body fat percentage in patients with PCOS. In the control group, however, there were moderate or strong negative correlations between anthropometric measurements (BMI, body fat percentage, abdominal circumference, chest lateral diameter) and at least three different pulmonary function tests. CONCLUSION: These results suggest that the upper body anthropometry and respiratory function relations might have impaired in patients with PCOS. We think that this situation might support the increased tendency for poor health status in patients with PCOS.

Serum MicroRNA Biomarkers Regulated by Simvastatin in a Primate Model of Endometriosis.

Endometriosis is a chronic inflammatory and estrogen-dependent disease that causes pain and infertility in reproductive-aged women. Due to the delay in diagnosis, there is a pressing need for accurate biomarkers. Detection of serum noncoding RNA molecules such as microRNAs (miRNAs) shows promise as a noninvasive diagnostic strategy; we previously identified miRNAs that are highly sensitive and specific biomarkers for the disease. In this study, we investigate the expression of these miRNAs in a nonhuman primate model of endometriosis. As part of a pilot study evaluating simvastatin for the treatment of endometriosis, the disease was induced in 16 baboons by induction laparoscopy and the animals were divided into 2 groups. One group was treated with simvastatin for 90 days, while the second group received vehicle only. Endometriosis was evaluated after 3 months by laparoscopy. Serum samples were analyzed for 9 circulating miRNAs using quantitative real time-polymerase chain reaction, focusing on the miRNAs we found to be dysregulated in human endometriosis. In the simvastatin-treated endometriosis group, levels of miR-150-5p and miR-451a were decreased, while miR-3613-5p levels were increased compared to the untreated endometriosis group. The changes in circulating miRNA expression patterns parallel our previous results in human patients and show that specific miRNAs correlate with endometriosis severity and reverted toward control expression levels after simvastatin treatment. This is the first report showing serum miRNA expression normalized in response to endometriosis treatment, supporting the potential for this class of biomarkers to be used both to diagnose endometriosis and to monitor its progression and response to therapy.

Insulin sensitivity does not differentiate by hirsutism in non-obese women with polycystic ovary syndrome.

OBJECTIVE: Hirsutism is one of the component of polycystic ovary syndrome. According to the Rotterdam Consensus has concluded that principially obese women with polycystic ovary syndrome (PCOS) should be evaluated for the metabolic syndrome. The aim of the present study was to investigate the insulin sensitivity in PCOS women with and without hirsutism regardless of obesity. MATERIAL AND METHODS: Clinical characteristics, sex hormones and fasting glucose and insulin levels of fifty-eight women with PCOS were analyzed. Hirsutism has been evaluated through the Ferriman-Gallwey (FG) map scoring system. RESULTS: Twenty-two women (38%) were hirsute. They were not any significant difference between hirsute and nonhirsute women for their sex steroids and insulin sensitivity (P>0.05). There were no correlation among sex steroids, WHR and insulin sensitivity in relation to FG score in the subgroup with hirsutism (P>0.05). CONCLUSION: Our study suggests that normal weight and overweight women with hirsutism can have normal insulin sensitivity and normal levels of circulating androgens in PCOS women.

Nausea and vomiting in early pregnancy: relationship with anxiety and depression.

OBJECTIVE: To investigate the association between either depression or anxiety early in pregnancy, and nausea and vomiting, in a clinical sample. METHODS: Anxiety and depression scores of 230 women were investigated by using the Hospital Anxiety and Depression Scale. Nausea and vomiting of pregnancy (NVP) were scored by using the Rhode's system. These scores and demographic data were compared and P < 0.05 was considered significant. RESULTS: A significant correlation between Rhode's score and both anxiety (r=0.388, P < 0.001) and depression score, (r=0.351, P < 0.001) was found. Gestational age showed and inverse correlation with anxiety scores (P=0.019). There was no significant correlation between demographic data and anxiety/depression scores, or Rhode's scores. CONCLUSION: There is an association between anxiety and depression early in pregnancyand severity of NVP.

Body fat composition and distribution in women with polycystic ovary syndrome.

OBJECTIVES: The aims of the present study were to compare the distribution and accumulation of body fat in women with polycystic ovary syndrome (PCOS) and healthy controls matched for age and body mass index (BMI), and to investigate the association between androgen levels, insulin resistance and fat distribution. MATERIALS AND METHODS: Thirty-one PCOS women and 29 age- and BMI-matched healthy control women were evaluated in terms of subcutaneous adipose tissue thickness determined with a skinfold caliper and body composition analyzed by bioelectrical impedance analysis. Blood samples were obtained for determination of follicle-stimulating hormone, luteinizing hormone, 17beta-estradiol, 17-hydroxyprogesterone, basal prolactin, testosterone, dehydroepiandrosterone sulfate, sex hormone-binding globulin (SHBG), androstenedione, insulin and glucose levels. Insulin sensitivity was estimated by fasting glucose/insulin ratio and free androgen index (FAI) was calculated as 100 x testosterone/SHBG. Differences between means were analyzed by Student's t test or the Mann-Whitney U test according to distribution of the data. Correlation analysis was performed between the body fat distribution and parameters concerning insulin resistance and androgens. RESULTS: FAI was significantly higher in patients with PCOS compared with the control group (p = 0.001). Fasting insulin was significantly higher and fasting glucose/insulin ratio was significantly lower in the PCOS group vs. controls (p = 0.03 and 0.001, respectively). There was significantly less subcutaneous adipose tissue in the controls than the PCOS women at the triceps (p = 0.04) and subscapular region (p = 0.04). Waist-to-hip ratio of PCOS women was significantly higher than that of control subjects (p = 0.04). CONCLUSION: Upper-half type body fat distribution is linked with PCOS, high free testosterone levels and insulin resistance.

Resting metabolic rate and exercise capacity in women with polycystic ovary syndrome.

OBJECTIVE: To assess the resting metabolic rate (RMR) and exercise capacity (or maximal oxygen consumption [VO2 max]) of women with polycystic ovary syndrome (PCOS) and central adiposity. METHOD: In a cross-sectional study, RMR was measured by indirect calorimetry and VO2 max by the Astrand test for 31 women with PCOS and 29 controls matched for age and body mass index, but with a different body fat distribution. Differences between the means were analyzed. RESULTS: There were no significant differences in RMR or VO2 max values between the 2 groups. CONCLUSION: Central adiposity was not predictive of an altered RMR or of decreased exercise capacity in women with PCOS.

Obstructive sleep apnea in pregnancy and fetal outcome.

OBJECTIVE: To simultaneously investigate the polysomnography (PSG) and nonstress test (NST) records of pregnant women with obstructive sleep apnea (OSA) to observe NST changes during maternal desaturation and determine maternal and fetal outcomes. METHODS: A prospective observational study of pregnant women assessed by questionnaire for symptoms of OSA. Women with self-reported frequent snoring or apnea were offered PSG and NST. RESULT: OSA was diagnosed in 4 (11.4%) of the 35 pregnant women who underwent PSG. Three (75%) had fetal heart decelerations accompanying maternal desaturation. The neonates of women diagnosed with OSA had lower mean Apgar scores and birth weights compared with neonates of women without OSA. Three neonates from the women diagnosed with OSA were admitted to the newborn healthcare unit. CONCLUSION: OSA in pregnancy has important maternal and fetal outcomes. Pregnant women should be assessed for symptoms of OSA and suspected cases should be offered PSG.

Arterial stiffness and dipper/nondipper blood pressure status in women with preeclampsia.

INTRODUCTION: The aim of this study was to investigate the clinical relevance of dipper status in women with preeclampsia by comparing arterial stiffness index (SI) values, and dipper and nondipper status. METHODS: A total of 60 pregnant women in their third trimester were enrolled in the study. SI values were measured using a digital photoplethysmographic method (Pulse Trace System, Micro Medical Ltd., Gillingham, Kent, UK). Twenty-four-hour ambulatory blood pressure was measured by a SpaceLabs 90217 oscillometric device (SpaceLabs Inc., Redmond, WA, USA). Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and pulse pressure (PP) were recorded. Those preeclamptic women whose mean nighttime blood pressure measurements were at least 10% lower compared with mean daytime measurements were classified as dipper status, and those with a decrease of less than 10% were classified as nondipper status. RESULTS: Seventeen women were preeclamptic with a dipper status, 13 women had nondipper status preeclampsia, and 30 women were normotensive. SI values were significantly higher in preeclamptic women compared with normotensive women (8.8+/-1.2 m/s vs. 5.9+/-0.8 m/s, P<0.001), but SI values of preeclamptic women with dipper status and preeclamptic women with nondipper status did not differ significantly from each other (P=0.485). CONCLUSION: There was no significant difference in SI values between the dipper and nondipper preeclamptic groups. These results indicate that dipper and nondipper measurements may not be suitable for clinical follow-up of preeclamptic women.

A prenatal diagnosed case of primitive neuroectodermal tumor.

Congenital brain tumors presenting in the first year of life account for 1.4-8.5% of all childhood brain tumors. Only 18% of congenital brain tumors are diagnosed before or at delivery. Primitive neuroectodermal tumor (PNET) is a highly malignant, small, blue-cell tumor which is characterized by early recurrence, metastasis, and high mortality. It makes up 13% of all fetal and neonatal brain tumors. Prenatal diagnosis of PNET or other congenital brain tumors is important because the presence of tumors may alter the time and mode of delivery and postnatal care planning. A prenatal case of PNET is described that was diagnosed with ultrasonography and magnetic resonance imaging; the case was confirmed histopathologically at postmortem examination.

Prenatal diagnosis of a fetal intracranial immature teratoma.

Congenital intracranial teratoma is a rare disease. A fetus with a congenital intracranial teratoma presenting with a hydrocephalus at 27 weeks' gestation is presented. Prenatal ultrasonography and fetal magnetic resonance imaging demonstrated a huge, heterogeneous intracranial mass including the infra- and supratentorial region and polyhydramnios. At 28 weeks' gestation, a cesarean section was performed to avoid divisive operation during delivery. The infant died after 10 min from respiratory failure. Histological examination revealed the diagnosis of immature teratoma. Early detection of congenital intracranial tumors is crucial. The prognosis is poor with death usually occurring shortly after birth.

Oxidative stress markers in pregnant women who snore and fetal outcome: a case control study.

BACKGROUND: To determine the levels of oxidative stress markers in pregnant women who snore and compare with non-snoring pregnant women. Fetal outcome of these 2 groups was also evaluated. MATERIALS AND METHODS: Prospective, case control study. Some 40 pregnant women who snored and 43 non-snoring pregnant women were evaluated. The glutathione peroxidase (GSH-Px), malondialdehyde (MDA) and myeloperoxidase (MPO) levels of the 2 groups were studied. Infant birthweight, Apgar scores, and other indicators of fetal outcome were obtained. RESULTS: The mean level of GSH-Px was significantly lower in the pregnant women who snored (p=0.005), while the mean level of MDA was significantly higher in this group (p=0.005). Levels of MPO were comparable between the groups (p>0.05). The pregnant women who snored did not have infants with evidence of an increase in compromised outcome. CONCLUSION: Although the pregnant women who snored had high levels of MDA, they did not appear to be at increased risk for delivering infants with fetal compromise.

Intracranial mucocele in pregnancy.

Intracranial mucocele is rare. They are slow-growing lesions and usually form as a result of an obstruction of the paranasal sinuses, particularly by osteoma, fibrosis, trauma, previous surgery or inflammation. The effect of pregnancy in the development of intracranial mucocele is unclear. We report a pregnant patient who was admitted to our clinic with severe headache and diplopia. A giant mucocele in the right frontal lobe was detected on magnetic resonance imaging. The patient underwent surgery with satisfactory outcome.

Bone Marrow Stem Cell Chemotactic Activity Is Induced by Elevated CXCl12 in Endometriosis.

Endometriosis is an inflammatory gynecological disorder caused by the growth of endometrial tissue outside the uterus. Endometriosis produces chemokines, including CXCL12, that attract bone marrow cells to the lesions. In this study, we describe the expression, localization, and chemotactic activity of CXCL12 in endometriotic lesions. Biopsies were collected both from women with endometriosis undergoing laparoscopy and control endometrium from women without endometriosis. Expression of CXCl12 and CXCR4 messenger RNA was increased approximately 4- and 6-fold, respectively, in endometriosis compared to eutopic endometrium. Immunohistochemistry of lesions revealed that CXCR4 was expressed in the stroma and epithelium in both endometriosis and control eutopic endometrium. The level of CXCR4 protein expression was significantly higher in all cellular compartments of the endometriotic lesions compared to control endometrium. CXCL12 protein expression was also higher in endometriotic lesions and was greatest in the epithelial compartment. CXCL12 was increased more in the condition media of cultured endometriosis than in controls as measured by enzyme-linked immunosorbent assay. Transwell chamber migration was used to demonstrate 2-fold increased chemoattraction of mouse bone marrow stem cells toward CXCL12 in the endometriotic-conditioned medium compared with eutopic endometrium. Our results indicate that a preferential recruitment of stem cells to endometriosis can explain how endometriosis outcompetes eutopic endometrium in recruiting the limited supply of circulating stem cells. The CXCL12/CXCR4 signaling axis is a potential target for the treatment of endometriosis and its associated disorders.

Medical Therapies for Endometriosis Differentially Inhibit Stem Cell Recruitment.

OBJECTIVE: To determine the effect of the 3 well-known endometriosis treatments on stem cell recruitment to endometriotic lesions. STUDY DESIGN: C57BL/6 mice (aged 8 weeks, n = 20) underwent bone marrow transplant following submyeloablation with 5-fluorouracil using 20 × 106 bone marrow stem cells from green fluorescent protein (GFP) mice. Two weeks after transplantation, experimental endometriosis was created in mice by suturing segments of the uterine horn into the peritoneal cavity. Mice were then randomized to receive treatment with medroxyprogesterone acetate (MPA), leuprolide acetate (Gonadotrophin-Releasing Hormone Analogue [GnRHa]), letrozole, or vehicle control (dimethyl sulfoxide). After 3 weeks of treatment, the mice were killed and the endometriosis lesions evaluated. RESULTS: All 3 treatments resulted in a significant reduction in lesion volume and weight. Estrogen deprivation using GnRHa or letrozole resulted in greater lesion regression than the progestin MPA. The GFP+/CD45- bone marrow-derived stem cells (BMDSCs) engrafted the lesions of endometriosis. Estrogen deprivation using GnRHa or letrozole significantly reduced BMDSC engraftment in the endometriosis lesions. MPA failed to significantly reduce stem cell number in endometriosis. CONCLUSION: The superiority of estrogen deprivation over progestin therapy in depriving the lesions of stem cells may have implications for the long-term treatment of endometriosis. Reduced stem cell engraftment is likely to result in long-term regression of the lesions, whereas progestins may only prevent their growth acutely.

CXCL12 Promotes Stem Cell Recruitment and Uterine Repair after Injury in Asherman's Syndrome.

Asherman's syndrome is an acquired condition of uterine fibrosis and adhesions in response to injury that adversely affects fertility and pregnancy. We have previously demonstrated that bone marrow-derived mesenchymal stem cells (BMDSCs) contribute to uterine repair after injury and that stem cells supplementation improves fertility. Here, we demonstrate that CXCL12 is the chemokine that mediates stem cell engraftment and functional improvement using a murine model of Asherman's syndrome. After uterine injury, we demonstrate that CXCL12 augmentation increased BMDSC engraftment and that the CXCL12 receptor (CXCR4) antagonist, ADM3100, blocked stem cell recruitment. CXCL12 reduced, whereas ADM3100 increased fibrosis. CXCL12 treatment led to improved fertility and litter size, whereas ADM3100 treatment reduced fertility and litter size. ADM3100 prevented optimal spontaneous uterine repair mediated by endogenous CXCL12 production, reducing pregnancies after injury in the absence of supplemental CXCL12 administration; however, ADM3100 treatment could be partially rescued by CXCL12 augmentation. CXCL12 or other CXCR4 receptor agonists may be useful in the treatment of infertility or adverse pregnancy outcomes in Asherman's syndrome and other related uterine disorders.
