Background Although cognitive behavioural therapy (CBT) is claimed to be effective in schizophrenia, major depression and bipolar disorder, there have been negative findings in well-conducted studies and meta-analyses have not fully considered the potential influence of blindness or the use of control interventions.Method We pooled data from published trials of CBT in schizophrenia, major depression and bipolar disorder that used controls for non-specific effects of intervention. Trials of effectiveness against relapse were also pooled, including those that compared CBT to treatment as usual (TAU). Blinding was examined as a moderating factor.Results CBT was not effective in reducing symptoms in schizophrenia or in preventing relapse. CBT was effective in reducing symptoms in major depression, although the effect size was small, and in reducing relapse. CBT was ineffective in reducing relapse in bipolar disorder.Conclusions CBT is no better than non-specific control interventions in the treatment of schizophrenia and does not reduce relapse rates. It is effective in major depression but the size of the effect is small in treatment studies. On present evidence CBT is not an effective treatment strategy for prevention of relapse in bipolar disorder. © Copyright Cambridge University Press 2009.

There have been two national British Thoracic Society (BTS) bronchiectasis audits from 1 October to 30 November in 2010 and 2011 in patients with non-cystic fibrosis attending secondary care. The first audit was soon after the publication of the BTS guidelines in July 2010 and both audits were based on the BTS guideline recommendations. We had 1460 and 2404 records in the 2 years respectively. The national audits highlight that the majority of guideline recommendations were not currently being adhered to and demonstrate the need for national quality standards, which are currently in preparation.

Objectives: To investigate the reliability of cefoxitin and oxacillin for the detection of mecC-positive Staphylococcus aureus. Methods: The susceptibility to cefoxitin and oxacillin of 62 mecC-positive S. aureus isolateswas investigated using broth microdilution, agar dilution, Etest and disc diffusion on different types of media. The data were interpreted for the utility of cefoxitin and oxacillin in conjunction with the stated methodologies for the detection of mecC-positive isolates. Results: Cefoxitin with Mueller-Hinton media fromBecton Dickinson and Oxoid detected all mecC-positive isolates when tested by broth microdilution, agar dilution and disc diffusion. By Etest, one isolate was falsely susceptible. Mueller-Hinton agar from bioMérieux was substantially less able to detect these isolates. One isolate was falsely susceptible by agar dilution when using Iso-Sensitest and Columbia agar. Disc diffusion using cefoxitin on Iso- Sensitest agar missed 29% of the isolates. For oxacillin, only agar dilution on Columbia agar+2% NaCl was able to detect all mecC-positive isolates successfully. Conclusions:Cefoxitin used withEUCASTmethodologyandoxacillin used with agardilutiononColumbia agar+2% NaCl detected all mecC-positive isolates. These methods with their concomitant agars should be preferred over Iso-Sensitest, which is recommended by the BSAC. It should be noted that for disc diffusion Mueller-Hinton media from bioMérieux performed poorly, with 26%-47% of mecC isolates being falsely susceptible. © The Author 2013.

This is the first report to characterize the genotypes and subtypes of Cryptosporidium species infecting a geographically isolated population of feral Soay sheep (Ovis aries) on Hirta, St. Kilda, Scotland, during two distinct periods: (i) prior to a population crash and (ii) as host numbers increased. Cryptosporidium DNA was extracted by freeze-thawing of immunomagnetically separated (IMS) bead-oocyst complexes, and species were identified following nested-PCR-restriction fragment length polymorphism (RFLP)/PCR sequencing at two Cryptosporidium 18S rRNA loci. Two hundred fifty-five samples were analyzed, and the prevalent Cryptosporidium species in single infections were identified as C. hominis (11.4% of all samples tested), C. parvum (9%), C. xiaoi (12.5%), and C. ubiquitum (6.7%). Cryptosporidium parvum was also present with other Cryptosporidium species in 27.1% of all samples tested. Cryptosporidium parvum- and C. hominis-positive isolates were genotyped using two nested-PCR assays that amplify the Cryptosporidium glycoprotein 60 gene (GP60). GP60 gene analysis showed the presence of two Cryptosporidium genotypes, namely, C. parvum IIaA19G1R1 and C. hominis IbA10G2. This study reveals a higher diversity of Cryptosporidium species/genotypes than was previously expected. We suggest reasons for the high diversity of Cryptosporidium parasites within this isolated population and discuss the implications for our understanding of cryptosporidiosis. © 2013, American Society for Microbiology.

This study investigated "creep" in vancomycin and daptomycin MICs among methicillin-resistant Staphylococcus aureus (MRSA) isolates from blood cultures over a 5-year period in a hospital in the United Kingdom, using different susceptibility testing methods. Trends in vancomycin and daptomycin susceptibility were evaluated by using Etest performed prospectively on isolates in routine clinical practice from December 2007 to December 2010 (n = 102). Comparison was made to results from prospective testing of subcultures at the Scottish MRSA Reference Laboratory, using an automated system (Vitek 2) and retrospective testing (Etest and CLSI reference broth microdilution [BMD] method) of stored isolates from 2006 to 2010 (n = 208). Spearman's rank correlations revealed a significant increase in vancomycin MIC (P = 0.012) and a significant decrease in daptomycin MIC (P = 0.03) by year of study for Etest results from the time of isolation. However, neither trend was replicated in MICs from automated or retrospective testing. The Friedman test revealed a significant difference between vancomycin MICs obtained from the same samples by different testing methods (χ 2 [3 degrees of freedom] = 97; P < 0.001). MICs from automated testing and Etest analysis of stored isolates were significantly lower than those from Etest analysis at the time of isolation for both antibiotics (P < 0.001). Effects of storage on the MIC appeared within the first 6 months of storage. Inconsistent evidence on vancomycin MIC creep and the relevance of the MIC to clinical outcome may arise from differences in susceptibility testing methods, including storage of isolates. There is a need to standardize and streamline susceptibility testing of vancomycin against MRSA. Copyright © 2012, American Society for Microbiology. All Rights Reserved.

Background: Dermatophytes are the major cause of superficial mycoses in samples submitted to Clinical Mycology, Glasgow. The most prevalent species is Trichophyton rubrum as identified classically by microscopy and culture. Recent advances in polymerase chain reaction (PCR) technology were examined for the feasibility of introducing a T. rubrum real-time PCR assay into a routine diagnostic service. Objective: To improve the diagnostic mycology service by the introduction of a real-time PCR test for T. rubrum. Methods: The DNA from 4972 nail and skin samples was obtained using the Qiagen QIAsymphony automated extractor. This DNA was subjected to real-time PCR using T. rubrum-specific primers and a probe. Results: During phase 1 of the study, 862 samples were analysed; 446 of 470 specimens that grew T. rubrum were detected by PCR. Out of 4110 samples analysed during phase 2, 753 T. rubrum infections were diagnosed and reported within 72 h. A total of 3357 samples were negative for a fungal infection by PCR and microscopy; these were also reported within 72 h. Conclusions: A vast reduction in the turnaround times can be achieved using this technique as opposed to classical methods. Samples which are PCR negative but microscopy positive are still subjected to culture. Screening samples for their suitability for PCR prior to processing eliminates the application of PCR for T. rubrum on inappropriate samples such those from the scalp or pityriasis versicolor. © 2011 British Association of Dermatologists.

Over the past 5 years, a number of cases of legionellosis in Scotland have been associated with compost use; however, studies investigating sources of infection other than water systems remain limited. This study delivers the first comprehensive survey of composts commonly available in the UK for the presence of Legionella species. Twenty-two store-bought composts, one green-waste compost and one home-made compost were tested for Legionella by culture methods on BCYE-α medium, and the findings were confirmed by macrophage infectivity potentiator (mip) speciation. Twenty-two of the samples were retested after an enrichment period of 8 weeks. In total, 15 of 24 composts tested positive for Legionella species, a higher level of contamination than previously seen in Europe. Two isolates of Legionella pneumophila were identified, and Legionella longbeachae serogroup 1 was found to be one of the most commonly isolated species. L. longbeachae infection would not be detected by routine Legionella urinary antigen assay, so such testing should not be used as the sole diagnostic technique in atypical pneumonia cases, particularly where there is an association with compost use. The occurrence of Legionella in over half of the samples tested indicates that compost could pose a public health risk. The addition of general hygiene warnings to compost packages may be beneficial in protecting public health. © 2013 European Society of Clinical Microbiology and Infectious Diseases.

Lung cancer remains the most common cause of cancer-related mortality in Scotland, accounting for 28.9% of all cancer deaths in 2007.1 Current guidelines recommend assessment of patient fitness and operability by a multi-disciplinary team when selecting management options.2-6 Two of the most important prognostic markers are the stage of disease and ECOG performance status. The most commonly used cancer staging system is the tumour, node, metastasis (TNM) staging system, which is maintained by the American Joint Committee on Cancer (AJCC) and the International Union Against Cancer (UICC). In 1998, the International Association for the Study of Lung Cancer (IASLC) established The Lung Cancer Staging Project, collecting data on over 100,000 patients diagnosed with lung cancer between 1990-2000 worldwide, in order to revise the 6th edition TNM staging system for non-small cell lung cancer (NSCLC).7 The 7th edition was published in late 2009. This review of staging in NSCLC, includes a summary of the different staging techniques currently available and the 7th edition TNM staging system for NSCLC. 8 © 2010 Elsevier Ltd.

We analyzed 1,042 Cryptosporidium oocyst-positive slides (456 from raw waters and 586 from drinking waters) of which 55.7% contained 1 or 2 oocysts, to determine species/genotypes present in Scottish waters. Two nested PCR-restriction fragment length polymorphism (RFLP) assays targeting different loci (1 and 2) of the hypervariable region of the 18S rRNA gene were used for species identification, and 62.4% of samples were amplified with at least one of the PCR assays. More samples (577 slides; 48.7% from raw water and 51.3% from drinking water) were amplified at locus 1 than at locus 2 (419 slides; 50.1% from raw water and 49.9% from drinking water). PCR at loci 1 and 2 amplified 45.4% and 31.7% of samples containing 1 or 2 oocysts, respectively. We detected both human-infectious and non-human-infectious species/genotype oocysts in Scottish raw and drinking waters. Cryptosporidium andersoni, Cryptosporidium parvum, and the Cryptosporidium cervine genotype (now Cryptosporidium ubiquitum) were most commonly detected in both raw and drinking waters, with C. ubiquitum being most common in drinking waters (12.5%) followed by C. parvum (4.2%) and C. andersoni (4.0%). Numerous samples (16.6% total; 18.9% from drinking water) contained mixtures of two or more species/genotypes, and we describe strategies for unraveling their identity. Repetitive analysis for discriminating mixtures proved useful, but both template concentration and PCR assay influenced outcomes. Five novel Cryptosporidium spp. (SW1 to SW5) were identified by RFLP/sequencing, and Cryptosporidium sp. SW1 was the fourth most common contaminant of Scottish drinking water (3%). © 2010, American Society for Microbiology.

Water and food are major environmental transmission routes for Cryptosporidium, but our ability to identify the spectrum of oocyst contributions in current performance-based methods is limited. Determining risks in water and foodstuffs, and the importance of zoonotic transmission, requires the use of molecular methods, which add value to performance-based morphologic methods. Multi-locus approaches increase the accuracy of identification, as many signatures detected in water originate from species/genotypes that are not infectious to humans. Method optimisation is necessary for detecting small numbers of oocysts in environmental samples consistently, and further work is required to (i) optimise IMS recovery efficiency, (ii) quality assure performance-based methods, (iii) maximise DNA extraction and purification, (iv) adopt standardised and validated loci and primers, (v) determine the species and subspecies range in samples containing mixtures, and standardising storage and transport matrices for validating genetic loci, primer sets and DNA sequences. © 2009 Elsevier Inc.
