Serpin E1/PAI-1, N-terminal pro-brain natriuretic peptide (NTpro-BNP) and neuropilin-1 are markers which have been associated with endothelial dysfunction. However, data on the levels of these markers in PE is limited. The limited data on the pathophysiology of PE in relation to these markers necessitated the study. This was a multicentre case-control study conducted at the Obstetrics and Gynaecology Department of the Tamale Teaching Hospital, the Bawku Presbyterian Hospital and the Bolgatanga Regional Hospital. Out of 520 consenting pregnant women, 127 pregnant women met the inclusion criteria (53 with PE and 74 controls) and were included in this study. Venous, placental, cord and peripheral blood were collected for biomarker assay, haematological parameters and placental parasite determination. Placental tissue sections were obtained for placental malaria and histopathological lesions associated with hypoperfusion. Maternal heart rate and foetal umbilical artery Doppler impedance indices; resistance index (RI) and systolic diastolic (SD) ratio were determined to confirm utero-placental hypoperfusion. Significantly higher proportions of foeto-maternal complications; eclampsia, low birth weight (LBW), neonatal intensive care unit admissions (NICU), intrauterine growth restriction (IUGR), caesarian deliveries and early gestational age at delivery were associated with PE. Women with PE had lower concentrations of platelet (p = 0.02) whereas red cell distribution width (RDW) was markedly elevated (p = 0.01). NTPro-BNP concentration was markedly elevated (p = 0.01) in women with PE whereas neuropilin-1 concentration was lower (p = 0.03) compared to the non-PE group. Maternal heart rate was elevated in women with PE and Doppler resistance indices (RI and SD) were significantly elevated in foetuses of PE women than foetuses of the controls. Placental mal-perfusion lesions were higher in women with PE compared to the non-PE group. Women with PE had increased risk of adverse foeto-maternal complications, significantly associated with placental mal-perfusion lesions, had reduced platelet concentration and elevated RDW-CV levels. NTPro-BNP, RI and SD are elevated in women with PE whereas neuropilin-1 concentration is reduced. Significant changes in these pathological variables in PE women is indicative of significant derangement in endothelial function culminating in adverse maternal and perinatal outcomes of pregnancy.

Introduction Although seborrheic dermatitis (SD) is not lethal, it has a significant impact on the quality of life. Many cases of SD are managed with ketoconazole, but luliconazole has shown an equivalent or lower minimum inhibitory concentration (MIC), but not many studies have been done for its efficacy and safety in SD. With this in mind, we set out to conduct a study comparing the effectiveness, safety, and tolerability of Lulican™ (luliconazole 1% + salicylic acid 3% + ZPTO 1%) shampoo and Ketoconazole (Ketoconazole 2% + ZPTO 1%) shampoo in the treatment of SD. Materials and methods In this prospective, randomized, multi-center study, mild to moderate scalp SD patients were prescribed Lulican™ or Ketoconazole shampoo three times a week for a duration of four weeks. Effectiveness assessment was done with the Seborrheic-Dermatitis-Severity-Score (SDSS) and Physician-Global-Assessment (PGA), and quality of life was assessed with the help of the Scalpdex-23 questionnaire. Results At four weeks, 68% and 57.9% reduction was seen in SDSS in Lulican™ and Ketoconazole shampoo, respectively. Moreover, 58% and 44% of patients achieved excellent to moderate responses as per PGA with Lulican™ and ketoconazole shampoo, respectively. For safety, no statistical difference was reported, but product tolerability and subjective cosmetic acceptability were significantly better in the Lulican™ group as compared to the Ketoconazole group at the end of four weeks. The mean Scalpdex-23 score at week four was reduced by 35.7% and 21.1% in Lulican™ and ketoconazole groups, respectively (p<0.05). Conclusion While both treatments were successful in alleviating SD symptoms and were well tolerated, Lulican™ stood out as a preferred treatment option due to better quality of life (QoL) improvement in SD.

INTRODUCTION =: Bacteriuria during pregnancy is a frequent and important cause of morbidity and complications. Data on its occurrence in pregnant adolescents are still scarce. METHODS =: A cross-sectional study was conducted at a tertiary teaching hospital in São Paulo, Brazil. All adolescents (≤ 18 years) who came for prenatal care between January 2010 and January 2016 were included. Sociodemographic characteristics, medical history, obstetric history, and the results of laboratory tests were selected. A urine sample was aseptically collected from each patient to undergo microscopic and culture analysis. RESULTS =: A total of 388 pregnant adolescents averaging 15.30 ± 1.24 years of age were included. The frequency of bacteriuria in this group was 17.01% (66/388). The lack of sports practice (OR=8.65, 95% CI=1.09-68.39), the fact that pregnancy was desired (OR=2.17, 95% CI=1.08-4.34), and the use of hormonal methods of contraception (OR=2.46, 95% CI=1.04-5.84) turned out to be independent risk factors for bacteriuria. Protective factors were identified as late coitarche (OR = 0.75, 95% CI=0.57-0.98) and a urine culture analysis at a later gestational age (OR = 0.94, 95% CI=0.90-0.98). The most often isolated pathogens were Escherichia coli (49%) and Streptococcus agalactiae (18%). CONCLUSION =: Bacteriuria among pregnant adolescents is a relatively common condition. The infection risk of the urinary tract was increased by physical inactivity and seemingly by the influence of behavioral and sexual factors. Such results can help to identify patients at risk, favoring the early diagnosis of the urinary tract infections and optimizing prenatal care.

BACKGROUND: Drugs are a common cause of anaphylaxis, which is potentially life threatening.
OBJECTIVE: We sought to describe US patients with an emergency department (ED) visit or hospitalization for drug-induced anaphylaxis (DIA), including postdischarge follow-up care.
METHODS: By using International Classification of Diseases, Ninth Revision codes in the MarketScan Database, we identified all patients with an ED visit and/or hospitalization for DIA between 2002 and 2008 (index date = initial ED visit and/or hospitalization). Inclusion required continuous full insurance coverage ≥1 year in the pre- and postindex period. We examined patient factors during the preindex period, characteristics of the index event, and outcomes during the postindex period.
RESULTS: The cohort included 716 patients with an ED visit and/or hospitalization for DIA (mean age, 48 years; 71% women). Most patients (71%) were managed in the ED, and only 8% of the patients with DIA treated in the ED received epinephrine. For those admitted, patients were hospitalized for a median of 3 days, and 41% spent time in the intensive care unit. Cardiorespiratory failure occurred in 5% of the patients in the ED and 23% of the patients who were hospitalized. The patients with a concomitant allergic condition were more likely to see an allergist/immunologist than those without a concomitant allergic condition, but 82% did not receive any subsequent care with an allergist/immunologist in the 1 year after the ED visit and/or hospitalization for DIA.
CONCLUSIONS: Drugs are a common, yet under-recognized, cause of anaphylaxis. Only a small number of patients with DIA received epinephrine in the ED or had subsequent care with an allergist/immunologist. These findings are novel and identify areas for improvement in the care of individuals with DIA.

It has been hypothesized that micronutrient levels play a role in the immune response to vaccination; however, population-level research on the association between micronutrient levels and immune response to influenza vaccination is needed. In this study, we hypothesized that decreasing levels of nutrients would be associated with decreased hemagglutination inhibition (HAI) responses to influenza vaccination. Therefore, the purpose of this study was to determine whether serum vitamin A, vitamin E, or zinc levels are associated with influenza vaccine response determined by HAI titer in adults 65 years or older. Participants in this study included 205 community-dwelling adults 65 years or older who resided in Marshfield, WI, USA, from fall 2008 through spring 2009. Participants received trivalent influenza vaccine and donated blood samples before and 21 to 28 days after vaccination. Prevaccination levels of serum retinol, α-tocopherol, and zinc as well as prevaccination and postvaccination HAI titer levels were measured. No participants were vitamin A or vitamin E deficient; 20% had low serum zinc levels (<70 μg/dL). Continuous variables and categorical quartiles coding for vitamin A, vitamin E, and zinc levels were not related to prevaccination or postvaccination seroprotection or seroconversion for any of the vaccine components (influenza A [H1N1], A [H3N2], or B), after adjusting for age, sex, body mass index, and prevaccination HAI geometric mean titer. In conclusion, our study population showed no association between variations in levels of serum vitamin A, vitamin E, or zinc and influenza vaccine response as measured by HAI in adults older than 65 years. Thus, associations between micronutrients and other measures of vaccine response, such as cell-mediated immune parameters, should also be explored.

OBJECTIVE: Our aim was to identify moderators of the effects of a cognitive behavioral group-based prevention program (CB group) and CB bibliotherapy, relative to an educational brochure control condition and to one another, in a school-based effectiveness randomized controlled prevention trial.
METHODS: 378 adolescents (M age = 15.5, 68% female) with elevated depressive symptoms were randomized in one of three conditions and were assessed at pretest, posttest, and 6-month follow-up. We tested the moderating effect of three individual (baseline depressive symptoms, negative attributional style, substance use), three environmental (negative life events, parental support, peer support), and two sociodemographic (sex, age) characteristics.
RESULTS: Baseline depressive symptoms interacted with condition and time. Decomposition indicated that elevated baseline depressive symptoms amplified the effect of CB bibliotherapy at posttest (but not 6-month follow-up) relative to the control condition, but did not modify the effect of CB group relative to the control condition or relative to bibliotherapy. Specifically, CB bibliotherapy resulted in lower posttest depressive symptoms than the control condition in individuals with elevated, but not average or low baseline symptoms. We found no interaction effect for other putative moderators.
CONCLUSIONS: Our findings suggest that bibliotherapy is effective only in participants who have elevated depressive symptoms at baseline. The fact that no study variable moderated the effects of CB group, which had a significant main effect in reducing depressive symptoms relative to the control condition, suggests that this indicated prevention intervention is effective for a wide range of adolescents.

BACKGROUND: Prasugrel, a P2Y₁₂ adenosine diphosphate (ADP) receptor antagonist effectively inhibits ADP-mediated platelet activation and aggregation, and may be useful in reducing vaso-occlusive crises in sickle cell disease (SCD). In this study, we assess the effect of prasugrel on biomarkers of platelet activation and coagulation in patients with SCD.
METHODS: Twelve adult patients with SCD and 13 healthy subjects were examined before and after 12 ± 2 days of 5.0 or 7.5 mg/day oral prasugrel. Assessed cellular biomarkers included monocyte- and neutrophil-platelet aggregates, activated glycoprotein IIb-IIIa (GPIIbIIIa), P-selectin, CD40 ligand (CD40L), tissue factor (TF) expression on circulating platelets and on monocyte-platelet aggregates, and platelet-erythrocyte aggregates. Soluble biomarkers included CD40L, prothrombin fragment 1.2 (F1.2), thromboxane B₂ (TXB₂), P-selectin, and TF.
RESULTS: Patients with SCD had increased platelet baseline activation compared to healthy subjects, as measured by percentages of monocyte-platelet aggregates, neutrophil-platelet aggregates, and platelets expressing CD40L. Likewise, baseline levels of soluble F1.2 and TXB₂ were elevated in patients with SCD compared to healthy subjects. After 12 days of prasugrel, patients with SCD had a significant reduction in platelet-monocyte aggregates that was not observed in healthy subjects. Following prasugrel administration, those with SCD maintained higher levels of monocyte-platelet aggregates and soluble F1.2, but had lower levels of platelet-erythrocyte aggregates and soluble TF compared to healthy subjects.
CONCLUSIONS: These results provide evidence for chronic platelet activation in the SCD steady state, activation that was in part attenuated by prasugrel, thereby suggesting that ADP may mediate platelet activation in SCD.

BACKGROUND: Newer generation everolimus-eluting stents (EES) improve clinical outcome compared to early generation sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES). We investigated whether the advantage in safety and efficacy also holds among the high-risk population of diabetic patients during long-term follow-up.
METHODS: Between 2002 and 2009, a total of 1963 consecutive diabetic patients treated with the unrestricted use of EES (n=804), SES (n=612) and PES (n=547) were followed throughout three years for the occurrence of cardiac events at two academic institutions. The primary end point was the occurrence of definite stent thrombosis.
RESULTS: The primary outcome occurred in 1.0% of EES, 3.7% of SES and 3.8% of PES treated patients ([EES vs. SES] adjusted HR=0.58, 95% CI 0.39-0.88; [EES vs. PES] adjusted HR=0.29, 95% CI 0.13-0.67). Similarly, patients treated with EES had a lower risk of target-lesion revascularization (TLR) compared to patients treated with SES and PES ([EES vs. SES], 5.6% vs. 11.5%, adjusted HR=0.68, 95% CI: 0.55-0.83; [EES vs. PES], 5.6% vs. 11.3%, adjusted HR=0.51, 95% CI: 0.33-0.77). There were no differences in other safety end points, such as all-cause mortality, cardiac mortality, myocardial infarction (MI) and MACE.
CONCLUSIONS: In diabetic patients, the unrestricted use of EES appears to be associated with improved outcomes, specifically a significant decrease in the need for TLR and ST compared to early generation SES and PES throughout 3-year follow-up.

Our previous study has shown that aging and hypertension may alter apparent diffusion coefficient (ADC) and cerebral blood flow (CBF) and increase ischemic susceptibility in the non-ischemic rat brain. The present study wishes to further investigate whether aging and hypertension may influence cerebral diffusion/perfusion and increase ischemic susceptibility in the ischemic brain. Brain magnetic resonance (MR) imaging was examined 1day before and 1 and 7days after bilateral common carotid artery occlusion. Young and middle-aged normotensive Wistar-Kyoto rats and young and middle-aged spontaneously hypertensive rats (SHRs) were studied. Infarction occurred mainly in the parietal cortex and was larger in middle-aged SHRs than the other three groups (P<0.05). In pre-operation, ADC was higher and CBF was lower in middle-aged/hypertensive rats than young/normotensive rats (P<0.05). The ADC was higher in the parietal cortex of the rats with infarction at 7days when compared to the rats without infarction [receiver operating characteristic curve (ROC), P=0.001; binary logistic regression (BLR), P=0.006]. However, there was no difference in the hippocampus and thalamus. At day 1 post-operation, CBF reduced and ADC/CBF ratio elevated significantly in the parietal cortex of the rats with infarction when compared to the rats without infarction (CBF: ROC, P=0.002; BLR, P=0.017. ADC/CBF ratio: ROC, P=0.001; BLR, P=0.018). Our results demonstrated that pre-operation ADC and post-operation CBF and ADC/CBF ratio can be used as good MR markers in the prediction of ischemic susceptibility after cerebral hypoperfusion.

Dried plum has been reported to have potent effects on bone in osteopenic animal models, but the mechanisms through which bone metabolism is altered in vivo remain unclear. To address this issue, a study comparing the metabolic response of dried plum to the anabolic agent, parathyroid hormone (PTH), was undertaken. Six month-old female Sprague Dawley rats (n=84) were sham-operated (SHAM) or ovariectomized (OVX) and maintained on a control diet for 6wks until osteopenia was confirmed. Treatments were initiated consisting of a control diet (AIN-93M) supplemented with dried plum (0, 5, 15 or 25%; w/w) or a positive control group receiving PTH. At the end of 6wks of treatment, whole body and femoral bone mineral density (BMD) were restored by the two higher doses of dried plum to the level of the SHAM group. Trabecular bone volume and cortical thickness were also improved with these two doses of dried plum. Dried plum suppressed the OVX-induced increase in bone turnover as indicated by systemic biomarkers of bone metabolism, N-terminal procollagen type 1 (P1NP) and deoxypyridinoline (DPD). Dynamic bone histomorphometric analysis of the tibial metaphysis revealed that dried plum restored the OVX-induced increase in cancellous bone formation rate (BFR) and mineralizing surface (MS/BS) to the SHAM group, but some doses of dried plum increased endocortical mineral apposition rate (MAR). As expected, PTH significantly increased endocortical MAR and BFR, periosteal BFR, and trabecular MAR and BFR beyond that of the OVX and maintained the accelerated rate of bone resorption associated with OVX. Dried plum up-regulated bone morphogenetic protein 4 (Bmp4) and insulin-like growth factor 1 (Igf1) while down-regulating nuclear factor T cell activator 1 (Nfatc1). These findings demonstrate that in the adult osteopenic OVX animal, the effects of dried plum differ from that of PTH in that dried plum primarily suppressed bone turnover with the exception of the indices of bone formation at the endocortical surface.
