Attitudes and opinions of nursing and medical staff regarding the supply and storage of medicinal products before and after the installation of a drawer‐based automated stock‐control system

Objectives This study assessed the attitudes of Emergency Department (ED) staff regarding the introduction of an automated stock‐control system. The objectives were to determine attitudes to stock control and replenishment, speed of access to the system, ease of use and the potential for future uses of the system. The study was carried out in the Countess of Chester Hospital NHS Foundation Trust (COCH) ED, which is attended by over 65 000 patients each year.
Locked versus Nonlocked Plate Fixation for Hallux MTP Arthrodesis

Background: Dorsal plate fixation is used commonly for arthrodesis of the hallux first metatarsophalangeal (MTP) joint. Custom dorsal plates incorporating locking technology have been developed recently for applications in the foot to provide relative ease of application and theoretically superior mechanical properties. The purpose of this study is to compare the radiographic and clinical outcomes of patients undergoing hallux MTP joint arthrodesis using a locked plate, or a nonlocked plate. Materials and Methods: We compared consecutive patients who underwent hallux MTP arthrodesis for a variety of diagnoses with either a precontoured locked titanium dorsal plate (Group 1) or a precontoured, nonlocked stainless steel plate (Group 2). All patients were evaluated with radiographs, visual analog pain scale, American Orthopaedic Foot and Ankle Society (AOFAS) hallux score, and a detailed patient satisfaction survey. Results: There were 73 feet in Group 1 and 107 feet in Group 2. There was a trend toward a higher nonunion rate in Group 1 compared to Group 2. When considering only patients without rheumatoid arthritis (RA), the union rate was significantly higher in Group 2 compared to Group 1. Hardware failure and the overall complication rate was equivalent between the two Groups. Conclusion: As locked plate technology continues to gain popularity for procedures in the foot, it is important that clinical outcomes are reported. Locked titanium plates were associated with higher nonunion rates. Improved plate design, patient selection, and an understanding of plate biomechanics in this unique loading environment may optimize future outcomes for hallux MTP arthrodesis.

Health benefits of reducing NOx emissions in the presence of epidemiological and atmospheric nonlinearities

Recent epidemiological evidence suggests that the logarithm of concentration is a better predictor of mortality risk from long-term exposure to ambient PM2.5 and NO2 than concentration itself. A log-concentration-response function (CRF) predicts a heightened excess risk per unit concentration at low levels of exposure that further increases as the air becomes less polluted. Using an adjoint air quality model, we estimate the public health benefits of reducing NOx emissions, on a per-ton and source-by-source basis. Our estimates of benefits-per-ton assume linear in concentration and log-concentration CRFs for NO2 and a CRF that is linear in concentration for O3. We apply risk coefficients estimated using the Canadian Census Health and Environment Cohort. We find that a log-concentration CRF for NO2 leads almost consistently to larger benefits-per-ton than a linear in concentration CRF (e.g., $500 000 ton−1 compared to $270 000 ton−1 for Ottawa). We observe that concentrations gradually decline due to widespread, progressive emissions abatement, entailing increasing health benefits as a result of (1) a log-concentration CRF for NO2 and (2) the nonlinear response of O3 to NOx emissions. Our results indicate that NOx abatement has the potential to incur substantial and increasing health benefits, by up to five times with 85% emission reductions, for Canada into the future.
Neurite Outgrowth on Non‐permissive Substrates In Vitro is Enhanced by Ectopic Expression of the Neural Adhesion Molecule L1 by Mouse Astrocytes

Axonal regrowth in the lesioned central nervous system (CNS) of adult mammals is, in part, prevented by non‐permissive properties of glial cells and myelin. To test if ectopic expression of the neurite outgrowth promoting recognition molecule L1 will overcome these non‐permissive influences and promote neurite outgrowth, L1 was expressed in astrocytes of transgenic mice using regulatory sequences of the glial fibrillary acidic protein (GFAP) gene. Northern blot analysis of different transgenic lines revealed different levels of transgenically expressed L1. Cultured astrocytes derived from transgenic animals displayed L1 immunoreactivity at the cell surface and in situ hybridization and immunocytochemical analysis of optic nerves from adult transgenic mice localized L1 expression to astrocytes. Expression of L1 protein by transgenic astrocytes was significantly upregulated in lesioned optic nerves. When mouse small cerebellar neurons or chick dorsal root ganglion neurons were cultured on cryosections of lesioned optic nerves or astrocyte monolayers from transgenic mice, respectively, neurite outgrowth was increased up to 400% on tissue sections and 50% on astrocytes compared with similar preparations from non‐transgenic mice. The increase in neurite outgrowth on tissue sections or astrocyte monolayers from different transgenic lines was proportional to the different levels of L1 expression. Moreover, increased neurite outgrowth on these substrates was specifically inhibited by polyclonal L1 antibodies. In vivo, rescue of severed axons was enhanced in transgenic versus wild type animals, while regrowth of axons was slightly, but not significantly, increased. Together, our observations demonstrate that L1 promotes neurite outgrowth when expressed ectopically by astrocytes and that L1 is able to overcome, at least partially, the non‐permissive substrate properties of differentiated CNS glial cells in vitro.
Heterozygosity–fitness correlations: new perspectives on old problems

Heterozygosity–fitness correlations (HFC) have been studied in various organisms for more than two decades, but they are not universal. Although their detectability is limited by several factors (null alleles, inaccuracy of the phenotypic description of fitness, small sample sizes) the correlations appear intrinsically weak and often inconsistent across samples. Determining the origins of HFC is therefore a complex task. However, this issue might soon be resolved provided clear hypotheses and definitions are used (especially, if the problem of the neutrality of allozyme variation is not identified with the related issue of HFC), as well as new empirical (molecular markers) & theoretical (statistical models) tools.
Extracorporeal lung perfusion (ex-vivo lung perfusion)

Purpose of reviewThe number of patients listed for lung transplantation largely exceeds the number of available transplantable organs because of both a shortage of organ donors and a low utilization rate of lungs from those donors. A novel strategy of donor lung management, ex-vivo lung perfusion (EVLP), that keeps the organ at physiological protective conditions has shown great promise to increase lung utilization by re-evaluating, treating, and repairing donor lungs prior to transplantation. Recent findingsClinical trials using EVLP have shown the method to be well tolerated and it allows for reassessment and improvement in function from high-risk donor lungs from both brain death and cardiac death donors prior to transplantation. When these lungs were transplanted, low rates of primary graft dysfunction were achieved, and the early outcomes were similar to those with conventionally selected and transplanted lungs. Preclinical studies have also shown a great potential of EVLP as a platform for the delivery of novel therapies to repair injured organs ex vivo and thus further increase the donor lung utilization rate. SummaryDevelopment of an ex-vivo treatment arsenal ranging in complexity from pharmacologic to gene and cellular therapies will soon allow clinicians to utilize the full potential of the donor organ pool improving outcomes of lung transplantation.
Racial/Ethnic Differences in the Association between Obesity and Major Depressive Disorder: Findings from the Comprehensive Psychiatric Epidemiology Surveys

Objectives. This study examined whether the association between obesity and 12-month prevalence of major depressive disorder (MDD) varied according to racial/ethnic status and nativity in representative national samples of black, Latino, Asian, and non-Hispanic white people. Methods. We used data from the Comprehensive Psychiatric Epidemiology Surveys. Results. In analyses by gender, obesity was associated with an elevated risk of MDD among non-Hispanic white women (adjusted odds ratio [AOR] =1.73; 95% confidence interval [CI] 1.27, 2.35; p=0.001). Formal test for interaction revealed significant variation by race present between non- Hispanic white women and black, Latin, and Asian women. No significant differences were evident among men. In analyses by nativity, the association between obesity and MDD was significant among U.S.-born non-Hispanic white women (AOR=1.62; 95% CI 1.16, 2.27; p=0.001) and U.S.-born black women (AOR=1.29; 95% CI 1.01, 1.66; p=0.041). Significant interactions were present among U.S.-born white and black women, Latin women, and Asian women. No significant interactions were evident among foreign-born women. Similarly, no significant differences were present among native-born or foreign-born men. Conclusions. The findings suggest that the association between obesity and MDD varies according to racial/ethnic status and nativity. Understanding the link between obesity and depression may be imperative to designing interventions to address body weight maintenance and reduction strategies among women.
Unstable Composition of the Fecal Microbiota in Ulcerative Colitis During Clinical Remission

BACKGROUND AND AIM:Studies have identified abnormal characteristics of the gut microbiota in patients with active IBD, but whether the changes are causal or secondary to inflammation remains uncertain. We investigated dynamics of fecal microbiota in ulcerative colitis (UC) during remission by genomic technology.PATIENTS AND METHODS:Patients in clinical remission and on stable maintenance mesalazine therapy were recruited (N = 33). Fecal samples were collected at regular intervals over a period of 1 yr. Sixteen patients who remained in remission and eight healthy controls were included in the analysis. Variable V6 to V8 regions of the 16S rRNA gene in DNA extracts from fecal samples were amplified by polymerase chain reaction. Amplicons were separated by denaturant gradient gel electrophoresis, band profiles were compared by software, and similarity indices were calculated from densitometric curves.RESULTS:Band profiles showed unique patterns with low similarity index between individuals, suggesting host specificity in the predominant microbiota. Within the same individual, profiles were stable in controls but varied notably over time in patients. In controls, the similarity index was remarkably stable (78 ± 8% mean ± SD) over a period of 24 months. However, patients showed a steady decline in similarity index versus the initial profile, dropping down to 42 ± 24% at month 3 of follow-up and to 23 ± 19% at month 12 (P < 0.001). Biodiversity of the dominant microbiota, as estimated by number of bands, was lower in patients (17 ± 4) than controls (23 ± 4, P < 0.01). CONCLUSION:Molecular analysis of fecal bacteria in patients with inactive UC shows low biodiversity and temporal instability.
Differential based area efficient ROM-less Quadrature Direct Digital Frequency Synthesis

Quadrature Direct Digital Frequency Synthesis (QDDFS) is a technique which can generate sine and cosine values in digital domain. In this paper we present a novel architecture for implementing QDDFS, suitable for implementation in Very Large Scale Integration (VLSI). The algorithm is very simple, which leads to a reduced hardware complexity. It takes two seed values and depending upon the input frequency control word, the algorithm is capable of generating different frequencies. Hardware is ROM-less, making the proposed scheme more area efficient than ROM based lookup table algorithms. In terms of speed performance, the architecture proposed in this paper is more time efficient than COordinate Rotation DIgital Computer (CORDIC) based QDDFS and Singleton's Method. Simulation results show that the generated values are very close to the actual values.
Histamine H1-receptor blockade in humans affects psychomotor performance but not memory

Results from recent animal studies suggest an important role for histamine in memory functioning. Histaminergic drugs might prove beneficial for people suffering from memory impairment. To determine if histamine is involved in memory functioning this study evaluates the effects of histaminergic dysfunction on memory performance by administrating a H1-antagonist to humans. The study was conducted according to a 4-way, double-blind, crossover design in 20 healthy female volunteers, aged 18—45 years. On each test day subjects completed three test sessions: before and around 2 and 4 h after administration of single oral doses of dexchlorpheniramine 2 mg or 4 mg, scopolamine 1 mg or placebo. Drug effects were assessed using tests of memory, psychomotor and attention performance, and subjective alertness. Results showed that dexchlorpheniramine impaired performance in tests of spatial learning, reaction time, tracking and divided attention but showed no effects on working memory, visual memory, word learning or memory scanning. Scopolamine induced a similar pattern of effects. In addition, both drugs decreased subjective alertness. In conclusion results show that dexchlorpheniramine and scopolamine clearly impaired performance on psychomotor and attention tasks but do not suggest a specific role of the histaminergic system in learning and memory in humans.
The efficacy of melatonin administration on oocyte quality

The aim of the study was to evaluate the efficacy of melatonin administration on oocyte quality in women underwent in vitro fertilization (IVF) cycles. Eighty-five women undergoing IVF cycles were randomized in two groups during IVF–embryo transfer (ET) procedure, 40 women with melatonin treatment (A) and 45 women without melatonin treatment (B). Primary endpoint was the number of morphologically mature oocytes retrieved (MII oocytes). Secondary endpoints were fertilization rate per number of mature oocytes, embryo quality and pregnancy rate. There were no differences between two groups according to age, and peak estradiol levels. The mean number of oocytes (15.33 vs. 14.27) and the mean number of mature oocytes did not differ between the two groups (12.63 vs. 10.94), whereas the percentage of mature oocytes (M2/oocytes retrieved) was significantly different in melatonin-treated group (p < 0.05). Fertilization rate (72.75 vs. 71.16) did not differ between the two groups. The mean number of class 1 embryos resulted higher in the group A (3.28 vs. 2.53) (p < 0.05). Clinical pregnancy rate was in tendency higher in the group treated with melatonin, although the differences did not reach statistical significance. Melatonin is likely to improve oocyte and embryo quality in women undergoing IVF or intracytoplasmic sperm insemination (ICSI).
Extracorporeal life support for acute respiratory distress syndrome

: The morbidity and mortality of acute respiratory distress syndrome remain to be high. Over the last 50 years, the clinical management of these patients has undergone vast changes. Significant improvement in the care of these patients involves the development of mechanical ventilation strategies, but the benefits of these strategies remain controversial. With a growing trend of extracorporeal support for critically ill patients, we provide a historical review of extracorporeal membrane oxygenation (ECMO) including its failures and successes as well as discussing extracorporeal devices now available or nearly accessible while examining current clinical indications and trends of ECMO in respiratory failure.
Housing market trends and recent policies

 In the last year, the government has initiated a number of housing policies including equity loans and mortgage guarantees via the ‘Help to Buy’ programme and a revamped ‘Right to Buy’ scheme for council house tenants. In the short run, these policies were introduced to stimulate demand for housing and to revitalise the construction industry. They also reflect a longer-term objective, dating back to at least the 1980s, of encouraging wider homeownership.
Does use of a jig influence the precision of tibial plateau leveling osteotomy surgery?

OBJECTIVE To compare the precision of tibial plateau leveling osteotomy (TPLO) surgery when performed with or without a jig. STUDY DESIGN Cadaveric study. SAMPLE POPULATION Cadaveric, adult greyhound hindlimbs (n=9 pair). METHODS TPLO (n=18) was performed on each limb pair; 1 with and 1 without use of a jig. Measurements taken from pre- and postsurgical radiographs were osteotomy position, tibial plateau angle (TPA), varus-valgus malalignment, and tibial torsion. The null hypothesis was that TPLO precision was not affected by use of a jig. Student's t-test was used to investigate differences in TPA, osteotomy location, and frequency and extent of iatrogenic limb malalignment; P<. 05 was considered significant. RESULTS There were no significant differences in postsurgical TPA, tibial crest thickness, varus-valgus malalignment, or tibial torsion between TPLOs performed with or without a jig. Osteotomy location was significantly more distal when a jig was used (P=.03). CONCLUSIONS Jig use did not improve the precision of TPLO surgery. CLINICAL RELEVANCE Performing TPLO without a jig should reduce surgery time, eliminate complications related to placement of the distal jig pin and allow unhindered positioning of the osteotomy.
Minimally invasive surgical training: do we need new standards?

Whilst detailed discussion of the management of DM is outside the remit of a urological study, there are some important factors to be considered. Metformin is frequently recommended as a first-line agent in the management of type 2 DM [5]. It follows, therefore, that patients treated with metformin may be different from those requiring secondor third-line drugs and drug combinations; thus the cohort treated with metformin may be younger, exhibit better glycaemic control, and have improved renal function compared with those treated with other drugs and exogenous insulin. An important consideration is that rather than a protective effect being exerted by metformin, it may be that other hypoglycaemic agents have an adverse effect on NMIBC outcomes. Pioglitazone has recently been associated with an increased incidence of urothelial cancer when taken for >2 years, although effects on prognosis are not established [6]. Were the patients with diabetes not taking metformin in fact treated with hypoglycaemic agents implicated in the aetiology of bladder cancer? When considering the plausibility of biological mechanisms, the time-lag between exposure to carcinogen and the development of bladder cancer is pertinent. There is a prolonged time-lag between exposure to cigarette smoking and the development of bladder cancer, so are we ready to accept that drug exposure for a short time-scale is protective or causative? Finally, we must consider the clinical relevance of these findings. As metformin is the current first-line therapy, it may be contraindicated in those not prescribed it and conversion may not be possible. Notwithstanding the above caveats, when treating patients with NMIBC we are often embarking on a lifelong process of treatment and surveillance. We are obliged as doctors to consider the implications of common comorbidities in order to tailor treatment. In much the same way that we now consider metabolic syndrome when evaluating erectile dysfunction, in the future we may need to consider NMIBC and DM together, and work collaboratively with other healthcare professionals to optimize the management of both conditions.
Iron status in low‐birth‐weight infants, small and appropriate for gestational age. A follow‐up study

Iron nutrition was measured in 84 low‐birth‐weight infants. At birth, they were assigned to three groups: preterm infants appropriate for gestational age (n= 29); preterm infants small for gestational age (n= 17); and full‐term infants* small for gestational age (n= 38). A sub‐sample of infants was supplemented with iron 3 mg/kg from two to four months of age. At birth, preterm appropriate‐for‐gestational‐age infants had a lower hemoglobin concentration than full‐term small‐for‐gestational‐age infants (p < 0.01) and a higher serum ferritin than preterm small‐for‐gestational‐age infants (p < 0.05). In the non‐supplemented group, full‐term small‐for‐gestational‐age infants had significantly higher hemoglobin concentrations at four months of age. At this age, iron‐supplemented preterm infants appropriate or small for gestational age had significantly higher hemoglobin levels than non‐supplemented subjects, while iron supplementation did not have an effect on final hemoglobin concentration in full‐term small‐for‐gestational‐age infants. We conclude that preterm infants, irrespective of their adequacy for gestational age, show evidence of iron deficiency before four months of age. Full‐term infants do not develop iron deficiency up to this age.
Fungal Peritonitis in Peritoneal Dialysis: Risk Factors and Prognosis

Although less common than bacterial peritonitis, fungal peritonitis is associated with much higher morbidity and mortality. In this study, we aimed to determine the risk factors for fungal peritonitis in peritoneal dialysis patients. The records of 109 peritoneal dialysis patients were analyzed. A total of 86 episodes of peritonitis attacks were recorded. Nine (10.5%) of these attacks were fungal peritonitis attacks. The fungal peritonitis attack rate of the population was 1 attack per 480.1 patient months. In order to determine predisposing factors for fungal peritonitis patients, patients with bacterial peritonitis and with no peritonitis admitted immediately before and after those with fungal peritonitis were used as controls. There was no statistically significant difference between the bacterial and fungal peritonitis groups with respect to symptoms and signs. Obligatory peritoneal dialysis treatment due to access or other medical problems (p = 0.04) and serum albumin levels (p = 0.01) were found to be significantly related with fungal peritonitis (p = 0.04). The mortality rate was 11.1%. When compared with the mortality rate of bacterial peritonitis (1.8%) during the same period, it was found to be significantly higher (p = 0.0001). The catheter removal was performed within 2–7 days (mean = 5.2 days) of the fungal peritonitis attacks. In conclusion, we decided that because fungal peritonitis attacks end up with high morbidity and mortality, prompt diagnosis and removal of the catheter is mandatory. Diagnosis highly depends on culture results, as signs and symptoms usually do not differ from that of bacterial peritonitis. Low serum albumin levels and obligatory peritoneal dialysis treatment are found to be the risk factors for fungal peritonitis.
