The purpose of the present study was to compare next-morning responses of RMR and appetite to pre-sleep consumption of casein protein (CP) in pre- and postmenopausal women. The study was a randomised, crossover, double-blind, placebo-controlled trial. Seven sedentary premenopausal (age: 19·9 (sd 1·2) years; BMI: 23·1 (sd 2·6) kg/m2) and seven sedentary postmenopausal (age: 56·4 (sd 4·9) years; BMI: 26·3 (sd 3·5) kg/m2) women participated. During visit one, anthropometrics and body composition were measured. Following visit one, subjects consumed either CP (25 g) or placebo (PL) ≥2 h after their last meal and ≤30 min prior to sleep on the night before visits two and three. Visits two and three occurred ≥1 week after visit one and were 48 h apart. During visits two and three, RMR (VO2), RER and appetite were measured via indirect calorimetry and visual analogue scale, respectively. Anthropometrics and body composition were analysed by one-way ANOVA. RMR and measures of appetite were analysed using a 2 × 2 (menopause status × CP/PL) repeated-measures ANOVA. Significance was accepted at P ≤ 0·05. RMR was significantly lower in postmenopausal compared with premenopausal women under both conditions (P = 0·003). When consumed pre-sleep CP did not alter RMR, RER or appetite compared with PL when assessed next morning in pre- and postmenopausal women. These data contribute to growing evidence that pre-sleep consumption of protein is not harmful to next-morning metabolism or appetite. In addition, these data demonstrate that menopause may not alter next-morning RMR, RER or appetite after pre-sleep consumption of CP.

Background
Depression is a very common condition in the elderly, underdiagnosed and often an emerging public health issue, especially in developed countries where population is aging.
MethodsThe participants (103 patients) age 55 years or more, with diagnosis of Schizophrenia and other psychotic disorders, Mood disorders and Mental disorders due to general medical condition. The depressive status of the participants was determined clinically, using the GDS and the Cornell scale for depression in dementia when MMSE was > 15.
ResultsOf the 103 inpatients, 87 had MMSE score less than 24 and were included in the analysis. 23.1% had been clinically diagnosed as suffering from depression and taking antidepressants although 53.8% had CDS>6 and 57.3% had Cornell score >11 both indicative of depression. It appeared that clinicians were able to detect mainly severe major depression with mean CDS score=10.50, (sd = 1.5) and mean Cornell score=18 (sd = 4.3).
ConclusionsIn our sample of an elderly long term inpatient population with primary diagnosis of serious mental disorder, depression was under diagnosed and undertreated. Only severe major depression was detected.
It appears that psychometric scales like Geriatric Depression Scale (GDS) and Cornell Scale for Depression in Dementia (CSDD) are valuable instruments for the detection of depression in elderly populations. As depression is very good in hiding or camouphlage its’ symptoms as part of other disorders, regular use of psychometric scales could prove to be an easy way to detect early signs of depression and treat accordingly.

Introduction:
Behavioral disorders, such as agitation and disability in daily skills, include symptoms of disturbed perception, thought content, mood or behavior that frequently occur in patients with dementia. These behavioral disturbances rather than cognitive disorders are the main reason why caregivers place patients in a nursing home.
Methods:The participants (103 patients) age 55 years or more had diagnosis of Schizophrenia and other psychotic disorders, Mood disorders and Mental disorders due to a general medical condition (DSM IV-TR criteria) from the psychogeriatric units of the psychiatric hospital of Attica. They were all assessed using the Neuropsychiatric Inventory (NPI) and Katz Instrumental Activities Scale (KATZ) to evaluate agitation, irritability and daily skills functionality.
Results:Of the sample of 103 Greek long term inpatients, 32% had clinical manifestation of aggression, 43.7% had severe daily skills dysfunction (with KATZ score 1–2), 19.4% moderate (KATZ score 3–4) and 36.9% had no dysfunction. NPI detected agitation in 55.3% of the sample and irritability in 49.5%.
Conclusions:Behavioral disturbances, agitation and disability in daily skills are common among older hospitalized patients, and psychometric scales like NPI and KATZ are valuable instruments that could prove to be an easy way to detect early signs of behavioral manifestations and exacerbation of a variety of mental disorders in elderly populations. They should be implemented in the usual clinical practice.

Introduction
People with severe mental disorders have worse physical health compared with the general population. Metabolic aspects such as obesity, diabetes, hypertension, dyslipidaemia, smoking and antipsychotic medication increase the risk of metabolic syndrome (MetS) and cardiovascular disease. Epidemiological studies have consistently shown excess CVD mortality in patients with schizophrenia, bipolar disorder and depression.
MethodsThe participants (103 patients) age 55 years or more, had diagnosis of Schizophrenia and other psychotic disorders, Mood disorders and Mental disorders due to a general medical condition(DSM IV-TR criteria). Metabolic syndrome was estimated using the ATP III definition.
Framingham risk score was calculated using algorithms developed by Wilson for subjects aged 30 years and older.
ResultsOverall prevalence of MetS was 34%. (37.1% men, 62,9% women). Among patients with MetS 74.3% had schizophrenia, 8.6.% Mood disorder and 17.1% Mental disorders due to a general medical condition. In our sample 18.8% of patients with MetS were receiving FGAs, 78.1% SGAs and 3.1% combination of FGAs and SGAs but this difference wasn’t statistically significant.
Low risk (FRS < = 14) had 68% of participants (21.4% men and 78.6% women). Moderate risk (FRS > 15) had 32% of participants (66.7% men, 33.3% women).
ConclusionsThe results indicate that patients with schizophrenia have higher probability of having MetS, therefore, clinicians should appropriately monitor the risk factors and intervene as required.

Introduction:
Cognitive impairment and loss of functionality are key characteristics of dementia and also highly prevalent among patients with serious mental illness. Our study reports on the prevalence of dementia and the relationship between cognitive decline, behavioral and social functioning disturbances, lifestyle/ physical health parameters and the pharmaceutical approaches, in an elderly population of the psychiatric hospital of Attica.
Methods:103 patients, aged 55 years or more, with diagnosis of Schizophrenia/other psychotic disorders, Mood disorders, and mental disorders due to a general medical condition (DSM-IV-TR) participated. Dementia was also defined according to DSM-IV-TR. Data collection was through their medical records and scales (Mini Mental State Examination, Clock Drawing Test, Global Deterioration Scale, Katz Index of Independence in Activities of Daily Living, Neuropsychiatric Inventory). All variables were statistically analyzed using the SPSS.
Results:Of the sample of 103 participants, 35.9% men, 64.1% women (mean age of 71), 60.2% had Schizophrenia, 7.8% Mood disorder, 32% Mental disorders due to a general medical condition. Dementia was diagnosed in 42 patients. 43,7% had severe daily skills dysfunction. Only 12,6% had no concomitant physical illness. Although they all had cognitive impairment, only 1/3 were treated with cognitive enhancers.
Conclusions:Long term mental disorder and long term hospitalization lead to severe deterioration of both cognitive function and daily skills abilities. Along with early screening for dementia, psychogeriatric patients need specific therapeutic approaches, promotion of favourable physical profile and amelioration of the consequences of the long term medication in their fragile health.

Objective
Due to concerns over increasing fluoroquinolone (FQ) resistance among gram-negative organisms, our stewardship program implemented a preauthorization use policy. The goal of this study was to assess the relationship between hospital FQ use and antibiotic resistance.
DesignRetrospective cohort.
SettingLarge academic medical center.
MethodsWe performed a retrospective analysis of FQ susceptibility of hospital isolates for 5 common gram-negative bacteria: Acinetobacter spp., Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Primary endpoint was the change of FQ susceptibility. A Poisson regression model was used to calculate the rate of change between the preintervention period (1998–2005) and the postimplementation period (2006–2016).
ResultsLarge rates of decline of FQ susceptibility began in 1998, particularly among P. aeruginosa, Acinetobacter spp., and E. cloacae. Our FQ restriction policy improved FQ use from 173 days of therapy (DOT) per 1,000 patient days to <60 DOT per 1,000 patient days. Fluoroquinolone susceptibility increased for Acinetobacter spp. (rate ratio [RR], 1.038; 95% confidence interval [CI], 1.005–1.072), E. cloacae (RR, 1.028; 95% CI, 1.013–1.044), and P. aeruginosa (RR, 1.013; 95% CI, 1.006–1.020). No significant change in susceptibility was detected for K. pneumoniae (RR, 1.002; 95% CI, 0.996–1.008), and the susceptibility for E. coli continued to decline, although the decline was not as steep (RR, 0.981; 95% CI, 0.975–0.987).
ConclusionsA stewardship-driven FQ restriction program stopped overall declining FQ susceptibility rates for all species except E. coli. For 3 species (ie, Acinetobacter spp, E. cloacae, and P. aeruginosa), susceptibility rates improved after implementation, and this improvement has been sustained over a 10-year period.

Intercropping systems that include legumes can provide symbiotically fixed nitrogen (N) and potentially increase yield through improved resource use efficiency. The aims of the present study were: (a) to evaluate the effects of different legumes (species and varieties) and barley on grain yield, dry matter production and N uptake of the intercrop treatments compared with the associated cereal sole crop; (b) to assess the effects on the yields of the next grain crop and (c) to determine the accumulation of N in shoots of the crops in a low-input rotation. An experiment was established near Edinburgh, UK, consisting of 12 hydrologically isolated plots. Treatments were a spring barley (Hordeum vulgare cvar Westminster) sole crop and intercrops of barley/white clover (Trifolium repens cvar Alice) and barley/pea (Pisum sativum cvar Zero4 or cvar Nitouche) in 2006. All the plots were sown with spring oats (Avena sativa cvar Firth) in 2007 and perennial ryegrass in 2008. No fertilizers, herbicides or pesticides were used at any stage of the experiment. Above-ground biomass (barley, clover, pea, oat and ryegrass) and grain yields (barley, pea and oat) were measured at key stages during the growing seasons of 2006, 2007 and 2008; land equivalent ratio (LER) was measured only in 2006. At harvest, the total above-ground biomass of barley intercropped with clover (4·56 t biomass/ha) and barley intercropped with pea cvar Zero4 (4·49 t biomass/ha) were significantly different from the barley sole crop (3·05 t biomass/ha; P<0·05). The grain yield of the barley (2006) intercropped with clover (3·36 t grain/ha) was significantly greater than that in the other treatments (P<0·01). The accumulation of N in barley was low in 2006, but significantly higher (P<0·05) in the oat grown the following year on the same plots. The present study demonstrates for the first time that intercrops can affect the grain yield and N uptake of the following crop (spring oats) in a rotation. Differences were also linked to the contrasting legume species and cultivars present in the previous year's intercrop. Legume choice is essential to optimize the plant productivity in intercropping designs. Cultivars chosen for intercropping purposes must take into account the effects upon the growth of the partner crop/s as well as to the following crop, including environmental factors.

The defensive glands of beetles, Tenebrio molitor, infected with metacestodes (cysticercoids) of Hymenolepis diminuta are everted less frequently upon stimulation, and contain less toluquinone (methylbenzoquinone) and m-cresol, than glands of uninfected controls. These differences, as shown in predation trials with wild rats, increase the likelihood that both cysticercoids and beetles will be ingested by the tapeworm's definitive host. This is the first documented case of a parasite inhibiting the chemical defence of an intermediate host, and one of only a few reports of parasite-induced manipulation of host biology supported by empirical evidence implicating facilitated parasite transmission between host species.

Objective:
To evaluate the risk of phlebitis associated with chlorhexidine-coated polyurethane catheters in peripheral veins.
Design:A randomized, double-blinded trial comparing chlorhexidine-coated polyurethane catheters with uncoated polyurethane catheters.
Setting:A university hospital.
Patients:Adult medicine and surgery patients.
Interventions:Certified registered nurse anesthetists or an infusion team consisting of nurses and physicians inserted the catheters. Catheter insertion sites were scored twice daily for evidence of phlebitis. At the time catheters were removed, a quantitative blood culture was performed, and catheters were sonicated for quantitative culture.
Results:Of 221 evaluable catheters, phlebitis developed in 18 (17%) of 105 coated catheters, compared to 27 (23%) of 116 uncoated catheters (relative risk [RR], 0.74; 95% confidence interval [CI95], 0.43-1.26; P=.32). By survival analysis, chlorhexidine-coated catheters had a lower risk of phlebitis during the first 3 days (P=.06), but not when all catheters were considered in both patient groups (P=.31). In the absence of catheter colonization, the incidence of phlebitis was 21% (16/76) and 24% (20/86) for coated and uncoated catheters, respectively (P=.85), whereas in the presence of catheter colonization, the incidence of phlebitis was 14% (1/7) and 80% (4/5) for coated and uncoated catheters, respectively (RR, 0.18; CI95, 0.03-1.15; P=.07).
Conclusion:The risk of phlebitis in the presence of catheter colonization was 82% lower for chlorhexidinecoated polyurethane catheters compared to otherwise identical uncoated catheters.

We report on a study of hard amorphous carbon thin films prepared by condensing streams of energetic carbon species, onto a range of substrates maintained at different temperatures. The carbon vapor is generated either by ion sputtering, laser ablation or e-beam evaporation. Spatially resolved electron-energy-loss spectra reveal variations in the films′ microstructure brought about by altering the deposition conditions. We estimate that the density of the different films varies between 2.0 and 3.26 g/cm3. We observe an evolution towards denser films upon increasing incident beam energy, reducing substrate temperature, and increasing substrate thermal conductivity. Low density films contain a predominance of trigonally bonded sp2-hybridized carbon (i.e graphitic carbon) and the highest density films contain a high fraction (∽ 80%) of tetr-ahedral sp3-bonded carbon (i.e. diamond-like).
