Citalopram and suicidality in adult major depression and anxiety disorders

The suicide-related data on citalopram from controlled clinical trials in depression and anxiety disorders were analysed. Safety data from placebo-controlled and relapse prevention citalopram trials in depression/major depressive disorder (MDD) and anxiety were searched for specific events relating to fatal suicide, non-fatal self-harm or suicidal thoughts. Efficacy data (item 10, suicidal thoughts, on the Montgomery–Åsberg Depression Rating Scale [MADRS]) were also analysed. In the clinical trial database, the number of adverse events (fatal suicide, non-fatal self-harm or suicidal thoughts) was low, both during the first 2 weeks of treatment and during the full treatment period, with no statistically significant differences between citalopram and placebo. There was one fatal suicide during treatment (after 12 weeks of double-blind treatment in a relapse-prevention trial) for a patient treated with citalopram (incidence: 0.4%; rate: 0.010) and none on placebo. Citalopram was significantly more efficacious than placebo in lowering suicidal thoughts, based on efficacy rating (MADRS, item 10). There was no indication from this review of clinical trial data that citalopram may increase the risk of suicide in patients with MDD or anxiety. However, the patients in these clinical trials represent a selected group, as those patients with a significant risk of suicide were excluded at trial onset.
Proton Magnetic Resonance Spectroscopy Assessment of Fetal Brain Metabolism in Late-Onset ‘Small for Gestational Age' versus ‘Intrauterine Growth Restriction' Fetuses

Objectives: We used magnetic resonance spectroscopy (MRS) to evaluate brain metabolic differences in small fetuses near term as compared to appropriate for gestational age (AGA) fetuses. Study Design: 71 term small fetuses (estimated fetal weight <10th centile for gestational age with normal umbilical artery Doppler sonography) were subclassified as late intrauterine growth restriction (IUGR) (n = 50) or small for gestational age (SGA) (n = 21), and compared with 65 AGA fetuses. IUGR was defined by either abnormal middle cerebral artery, abnormal uterine artery Doppler sonography or estimated fetal weight <3rd centile. All participants underwent brain magnetic resonance imaging at 37 weeks of gestation, and single-voxel magnetic resonance spectra were obtained from the frontal lobe on a 3-tesla scanner. N-acetylaspartate (NAA)/choline (Cho), NAA/creatine (Cr) and Cho/Cr ratios were calculated and compared between cases and controls. The association of the metabolic ratios with the study groups was tested. Results: After MRS processing and applying quality control criteria, 31 spectra from late-onset IUGR, 11 from SGA and 30 from AGA fetuses were selected for further analysis. Both SGA and late-onset IUGR fetuses showed significantly reduced NAA/Cho levels when compared to AGA fetuses. This decrease followed a linear trend across the three clinical groups that were considered. Conclusions: Both SGA and late-onset IUGR fetuses showed differences in MRS brain metabolic ratios. The findings suggest that despite near-normal perinatal outcomes, SGA fetuses are not constitutionally small and may represent a form of growth disorder that needs to be clarified.
Dietary glycemic index and load in relation to risk of uterine leiomyomata in the Black Women's Health Study.

BACKGROUND High dietary glycemic index (GI) and glycemic load (GL) may promote tumorigenesis by increasing endogenous concentrations of insulin-like growth factor I (IGF-I) or the bioavailability of estradiol. In vitro studies have shown that uterine leiomyoma (UL) cells proliferate in response to IGF-I and display increased IGF-I gene expression and protein synthesis. Previous epidemiologic studies suggest that a high GL is a risk factor for endometrial and ovarian cancers, which, like UL, are hormone-responsive tumors. OBJECTIVE We investigated the relation of dietary GI and GL with UL risk in the Black Women's Health Study. DESIGN In this prospective cohort study, we followed 21,861 premenopausal women for incident UL from 1997 to 2007. Diet was assessed in 1995 and 2001 with food-frequency questionnaires. We used Cox regression to estimate incidence rate ratios (IRRs) and 95% CIs, controlled for potential confounders. RESULTS During 162,604 person-years of follow-up, there were 5800 cases of UL diagnosed by ultrasound or surgery. Dietary GI was weakly associated with UL risk overall (IRR for highest compared with lowest quintile: 1.09; 95% CI: 0.99, 1.19; P for trend = 0.04). Positive associations were observed between GL and UL in women aged <35 y (IRR for highest compared with lowest quintile: 1.18; 95% CI: 1.02, 1.37; P for trend = 0.15) and between GI and UL in college-educated women (IRR for highest compared with lowest quintile: 1.17; 95% CI: 1.03, 1.34; P for trend = 0.004). CONCLUSIONS Our results suggest that high dietary GI and GL may be associated with an increased UL risk in some women. The observed associations warrant investigation in future studies.
Structural and Biochemical Properties of Fibroblast Growth Factor 23

Abstract: Fibroblast growth factor (FGF) 23 shares a fundamentally common structure with the members of the FGF family and has a unique sequence extension at the C‐terminus. The molecular behavior of FGF23 as a systemic factor can be justified by the altered conformation of the β‐trefoil structure similar to that suspected in FGF19. On the other hand, the biological activity of FGF23 is quite distinct from those of other FGFs and requires the C‐terminal unique extended structure. Two types of enzyme‐linked immunosorbent assays (ELISA) have been developed to detect the intact mature form of FGF23 and its C‐terminal portion. The former ELISA method enables the detection of rodent FGF23 and human FGF23. Studies on experimental animal models and laboratory examinations of physiologic and disordered conditions using these assays are contributing toward elucidating the physiology and pathophysiology of FGF23.
Radical budget and ozone chemistry during autumn in the atmosphere of an urban site in central China

The ROx (=OH + HO2 + RO2) budget and O3 production at an urban site in central China (Wuhan) during autumn were simulated and analyzed for the first time using a UW Chemical Model 0‐D box model constrained by in situ observational data. The daytime average OH, HO2, and RO2 concentrations were 2.2 × 106, 1.0 × 108, and 5.2 × 107 molecules cm−3, respectively. The average daytime O3 production rate was 8.8 ppbv h−1, and alkenes were the most important VOC species for O3 formation (contributing 45%) at this site. Our sensitivity test indicated that the atmospheric environment in Wuhan during autumn belongs to the VOC‐limited regime. The daily average HONO concentration at this site during the study period reached 1.1 ppbv and played an important role in the oxidative capacity of the atmosphere. Without the source of excess HONO, the average daytime OH, HO2, RO2, and O3 production rates decreased by 36%, 26%, 27%, and 31% respectively. A correlation between the HONO to NO2 heterogeneous conversion efficiency and PM2.5 × SWR was found at this site; based on this relationship, if the PM2.5 concentration met the World Health Organization air quality standard (25 µg m−3), the O3 production rate in this city would decrease by 19% during late autumn. The burning of agricultural biomass severely affected the air quality in Wuhan during summer and autumn. Agricultural burning was found to account for 18% of the O3 formation during the study period. Our results suggest that VOC control and a ban on agricultural biomass burning should be considered as high‐priority measures for improving the air quality in this region.
Efficacy of proactive long-term maintenance therapy of canine atopic dermatitis with 0.0584% hydrocortisone aceponate spray: a double-blind placebo controlled pilot study.

BACKGROUND Long-term remission between flares of canine atopic dermatitis (CAD) can be difficult to achieve. Therefore, additional strategic forms of treatment are needed in order to target flare prevention. The concept of proactive therapy is recommended in the European guidelines for the treatment of human atopic eczema. OBJECTIVES To evaluate the efficacy of a proactive treatment regimen with a 0.0584% hydrocortisone aceponate (HCA) spray for CAD. ANIMALS Client-owned dogs with spontaneous atopic dermatitis (AD) (n = 41). METHODS This pilot study was conducted as a randomised, placebo-controlled, double-blinded clinical trial with an end-point of treatment failure. Dogs were treated once daily to remission, then randomly assigned to receive either the HCA spray (n = 21) or a placebo (n = 20) spray on two consecutive days each week. All dogs were on appropriate flea control. No topical or systemic anti-inflammatory or antimicrobial agents were permitted. Intention-to-treat analysis was used. RESULTS At Day 0, all the dogs were in remission or had mild AD based on their Canine Atopic Dermatitis Extent and Severity Index, version 3 (CADESI-03) scores. The time to relapse was significantly higher in the HCA group (median 115 d; range 31-260 d) compared to the placebo group (median 33 d; range 15-61 d) (P < 0.0001). No adverse events were attributable to the HCA spray. Four dogs were lost to follow-up and four were withdrawn after receiving prohibited medication. CONCLUSIONS AND CLINICAL IMPORTANCE These results indicate that proactive long-term therapy of CAD with an HCA spray administered on two consecutive days each week is effective and well-tolerated.
Cortical magnetic stimulation in patients with genuine stress incontinence: Correlation with results of pelvic floor exercises

Pelvic floor training is an established conservative method of treatment in patients with genuine stress incontinence. It is not known why only a proportion of patients benefit from this form of treatment, while others with a comparable degree of incontinence do not. Since muscle awareness is of vital importance in pelvic floor training, we decided to investigate whether differences in outcome might be explained by differences in cortical control of the pelvic floor muscles. The function in the total motor pathway to the pelvic floor muscles was examined with cortical magnetic stimulation and circumvaginal EMG recording. Since lesions of the peripheral motor pathway have been demonstrated in patients with genuine stress incontinence, possible differences at this level were investigated by means of terminal pudendal motor latencies, using electrical nerve stimulation and anal recording EMG.
Screening for Congenital Hypothyroidism in Extreme Premature and/or Very Low Birth Weight Newborns: The Importance of a Specific Protocol

BACKGROUND Neonatal screening for congenital hypothyroidism (CH) in premature infants is not as well established as in term newborns regarding age and number of samples. AIMS 1. To evaluate the effectiveness of the protocol recommended by the Neonatal Screening Program of the State of Minas Gerais (PETN-MG) for CH neonatal screening in very low birth weight premature infants. 2. To estimate the prevalence of delayed TSH elevation and thyroid function alterations in the target population. METHODS TSH was assessed by ELISA on the 5th, 10th and 30th days of life in all newborns with gestational age <32 weeks and/or very low birth weight (VLB) (<1,500 g) in the period from October 2004 to September 2006. RESULTS Out of the 14,462 newborns screened, 2,647 were premature with gestational age <32 weeks and/or VLB. Forty-four cases of altered TSH were found and 11 infants underwent treatment. Delayed TSH elevation was detected in 66% of altered cases. Five out of the 11 cases were detected in the second sample and five cases were only detected in the third sample. CONCLUSION The high prevalence of thyroid function alterations that demanded treatment (1:242) and delayed TSH elevation in VLB premature infants reinforce the need for a specific protocol, based on retesting procedures, for CH neonatal screening.
Survey of aflatoxicosis in farm animals

Over a 22-month period, 278 submissions of farm animals were made to the North Carolina Diagnostic Laboratory for suspected aflatoxicosis, and 94 cases were confirmed on the basis of finding aflatoxin in the feed and the occurrence of bile ductule proliferation. There was an annual variation in the incidence of aflatoxicosis, as well as a seasonal variation: the peak incidence occurred in the winter, and the minimum incidence occurred during the summer. The annual increase coincided with the corn harvest. All confirmed cases occurred on farms that raised and stored their own corn, and 88% were in swine. The cases were geographically localized in the eastern section of North Carolina (94% of the total cases) where 82% of the swine and 79% of the corn are produced. Mean concentration of aflatoxin in feed samples from the confirmed cases was 3,890 mug/kg, and the mean value for corn used in making the feed was 5,180 mug/kg. Only aflatoxin B1 was found in the samples. These data were interpreted to mean that the incidence and severity of aflatoxicosis is greater than previously suspected, that poor on-farm storage of corn is a primary contributing factor, that aflatoxin formation continues during and after the milling process, and that mycotoxicoses other than aflatoxicosis may cause equal or greater problems.
Effects of CO(2) Enrichment and Carbohydrate Content on the Dark Respiration of Soybeans.

During the period of most active leaf expansion, the foliar dark respiration rate of soybeans (Glycine max cv Williams), grown for 2 weeks in 1000 microliters CO(2) per liter air, was 1.45 milligrams CO(2) evolved per hour leaf density thickness, and this was twice the rate displayed by leaves of control plants (350 microliters CO(2) per liter air). There was a higher foliar nonstructural carbohydrate level (e.g. sucrose and starch) in the CO(2) enriched compared with CO(2) normal plants. For example, leaves of enriched plants displayed levels of nonstructural carbohydrate equivalent to 174 milligrams glucose per gram dry weight compared to the 84 milligrams glucose per gram dry weight found in control plant leaves. As the leaves of CO(2) enriched plants approached full expansion, both the foliar respiration rate and carbohydrate content of the CO(2) enriched leaves decreased until they were equivalent with those same parameters in the leaves of control plants. A strong positive correlation between respiration rate and carbohydrate content was seen in high CO(2) adapted plants, but not in the control plants.Mitochondria, isolated simultaneously from the leaves of CO(2) enriched and control plants, showed no difference in NADH or malate-glutamate dependent O(2) uptake, and there were no observed differences in the specific activities of NAD(+) linked isocitrate dehydrogenase and cytochrome c oxidase. Since the mitochondrial O(2) uptake and total enzyme activities were not greater in young enriched leaves, the increase in leaf respiration rate was not caused by metabolic adaptations in the leaf mitochondria as a response to long term CO(2) enrichment. It was concluded, that the higher respiration rate in the enriched plant's foliage was attributable, in part, to a higher carbohydrate status.
A randomized clinical trial and meta-analysis of early surgery vs. initial conservative treatment in patients with spontaneous lobar intracerebral hemorrhage.

miR-513a-5p and mRNA transcribed from the susceptibility allele (A allele) of rs4148941 was enhanced in vitro compared with transcripts from other alleles. Additionally, expression of CHST3 mRNA was significantly reduced in the intervertebral disc cells of human subjects carrying the A allele of rs4148941. In theory, it makes sense that CHST3 should be implicated in the pathogenesis of LDD. CHST3 is known to play a key role in proper hydration and function of cartilaginous tissues. The proteoglycan aggrecan is concentrated in disc matrix and chondroitin sulphate glycosaminoglycan side chains are abundant. Appropriate sulfation of glycosaminoglycan side chains is important for water retention to maintain proper osmotic pressure to resist compressive forces within the nucleous pulposus. It seems to follow that activity of CHST3, an enzyme that catalyzes proteoglycan sulfation, would be important for intervertebral disc function, and that mutations of the gene could result in accelerated disc degeneration. Overall, their data suggest an interplay between genetic risk factors and miRNA, and provide new insights into the etiology of LDD. While these results are fascinating, their translation into clinical practice is limited at this time. But, in an effort to one day modify the risk factors of developing LDD, we must first come a long way in understanding the etiology behind the disease. In that sense, the work of Song et al brings us one step closer to that goal, opening up new targets for therapeutic intervention in the future.
A novel hantavirus associated with an outbreak of fatal respiratory disease in the southwestern United States: evolutionary relationships to known hantaviruses

Four Corners hantavirus (FCV) is the tentative name of the suspected etiologic agent of the newly identified hantavirus-associated respiratory distress syndrome (HARDS). The identification in HARDS patients of serum immunoglobulin M and immunoglobulin G antibodies that cross-reacted with Hantaan, Seoul, and Puumala virus antigens first suggested that FCV is a hantavirus. Limited nucleotide sequence data from the FCV glycoprotein-2 (G2) confirmed that FCV is a hantavirus and showed that it is most closely related to Prospect Hill and Puumala viruses. We have molecularly cloned approximately 95% of the sequences of the M and S segments of the FCV genome encoding the envelope glycoproteins and nucleocapsid protein N from the lungs of a patient with HARDS. The nucleotide sequence has been determined for 2,632 bases. The nucleotide sequence data show that FCV is a new member of the Puumala virus and Prospect Hill virus division of the hantavirus genus. Phylogenetic tree analyses indicate that the M and S segments have evolved in parallel. Therefore, the novel pathogenic activity of FCV is not likely to be the result of recent reassortment of segments from less pathogenic viruses.
Water jet rebounds on hydrophobic surfaces: a first step to jet micro-fluidics

When a water jet impinges upon a solid surface it produces a so called hydraulic jump that everyone can observe in the sink of their kitchen. It is characterized by a thin liquid sheet bounded by a circular rise of the surface due to capillary and gravitational forces. In this phenomenon, the impact induces a geometrical transition, from the cylindrical one of the jet to the bi-dimensional one of the film. A true jet rebound on a solid surface, for which the cylindrical geometry is preserved, has never been yet observed. Here we experimentally demonstrate that a water jet can impact a solid surface without being destabilized. Depending on the incident angle of the impinging jet, its velocity and the degree of hydrophobicity of the substrate, the jet can (i) bounce on the surface with a fixed reflected angle, (ii) land on it and give rise to a supported jet or (iii) be destabilized, emitting drops. Capillary forces are predominant at the sub-millimetric jet scale considered in this work, along with the hydrophobic nature of the substrate. The results presented in this communication raise the fundamental question of knowing why such capillary hydraulic jump gives rise to this unexpected jet rebound phenomenon. This study furthermore offers new and promising possibilities to handle a small quantity of water through “jet micro-fluidics”
Garlic extract and two diallyl sulphides inhibit methicillin-resistant Staphylococcus aureus infection in BALB/cA mice.

OBJECTIVES The inhibitory effect of garlic extract, diallyl sulphide and diallyl disulphide against methicillin-resistant Staphylococcus aureus (MRSA) infection in BALB/cA mice was studied. The influence of these agents upon the levels of fibronectin, interleukin-6 and lipid oxidation in MRSA-infected mice was examined. METHODS Garlic extract at 100% and 50%; diallyl sulphide (DAS) at 10% and 5%; diallyl disulphide (DADS) at 1% and 0.5% were used in this study. Sixteen clinical MRSA isolates obtained from infected patients were used in this study (n=16). Mice were infected by injecting 200 microL MRSA-PBS solution, which contained 10(7) cfu, via the tail vein. At 16 h post-infection (p.i.), garlic extract, DAS or DADS at 200 microL was administrated orally. At 24 h p.i. , mice were killed and blood, liver, kidney and spleen of each mouse were collected. Plasma and the filtrate from each organ and serial dilutions were used to determine colony count. Plasma fibronectin level was determined by rabbit anti-rat fibronectin antibody and quantified by ELISA. Interleukin-6 levels were determined by commercial kit. Lipid oxidation was determined by measuring malondialdehyde levels. RESULTS The oral administration of these agents significantly decreased the viability of MRSA, in plasma, liver, kidney and spleen (P<0.05). MRSA infection significantly increased fibronectin and interleukin-6 levels in plasma of MRSA-infected mice (P<0.05); however, the oral administration of garlic extract and two diallyl sulphides significantly reduced both fibronectin and interleukin-6 levels (P<0.05). MRSA infection also significantly enhanced lipid oxidation in plasma and three organs (P<0.05). The treatments of garlic extract and two diallyl sulphides significantly decreased the malondialdehyde level and showed antioxidant protection (P<0.05). CONCLUSIONS These data strongly supported the conclusion that garlic extract, diallyl sulphide and diallyl disulphide possessed multiple protective functions against MRSA infection, in which diallyl sulphide and diallyl disulphide could be considered as novel therapeutic agents for the treatment of MRSA infection.
Effects of Ethephon on the Hemolymph Metabolites of the Greater Wax Moth Galleria mellonella L. (Lepidoptera: Pyralidae)

Ethephon (ETF), one of the plant growth regulators, is used in agricultural systems as a valuable tool due to its property of regulating fruit maturation. Here, we aimed to investigate the toxic effects of ETF on the hemolymph metabolites of the greater wax moth, G. mellonella which is an experimental animal and a serious pest in wax. Different doses of ETF (250–390 μg/5 μl) were injected with force feeding method to the last instars and the effects of ETF on the level of hemolymph protein, lipid, and glucose were estimated spectrophotometrically at 24 and 48 h after treatments. The levels of protein, glucose, and lipid in hemolymph showed doseand time-dependent changes. These results indicated that treatment with ETF may result in significant physiological changes in pests. Consequently, it is likely that ETF can be a promising agent for use in integrated pest management programs as ecofriendly biopesticides.
Nationwide Survey of In Vitro Activities of Itraconazole and Voriconazole against Clinical Aspergillus fumigatus Isolates Cultured between 1945 and 1998

ABSTRACT The isolates in a collection of 170 Aspergillus fumigatus isolates recovered from 114 patients and 21 different medical centers in The Netherlands over a period of 53 years were tested for the presence of resistance to itraconazole and voriconazole according to the guidelines of NCCLS document M38-P and by the E-test. Three isolates were highly resistant to itraconazole, and voriconazole MICs were low for all isolates.
