TL;DR: The efficacy of CBT and particularly CBT-BN in the treatment of people with bulimia nervosa and also related eating disorder syndromes was supported, and other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term.
Abstract: Background
A specific manual-based form of cognitive behavioural therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN) and other common related syndromes such as binge eating disorder. Other psychotherapies and modifications of CBT are also used.
Objectives
To evaluate the efficacy of CBT, CBT-BN and other psychotherapies in the treatment of adults with bulimia nervosa or related syndromes of recurrent binge eating.
Search methods
Handsearch of The International Journal of Eating Disorders since first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PsycInfo, CURRENT CONTENTS, LILACS, SCISEARCH, CENTRAL and the The Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register; citation list searching and personal approaches to authors were used. Search date June 2007.
Selection criteria
Randomised controlled trials of psychotherapy for adults with bulimia nervosa, binge eating disorder and/or eating disorder not otherwise specified (EDNOS) of a bulimic type which applied a standardised outcome methodology and had less than 50% drop-out rate.
Data collection and analysis
Data were analysed using the Review Manager software program. Relative risks were calculated for binary outcome data. Standardised mean differences were calculated for continuous variable outcome data. A random effects model was applied.
Main results
48 studies (n = 3054 participants) were included. The review supported the efficacy of CBT and particularly CBT-BN in the treatment of people with bulimia nervosa and also (but less strongly due to the small number of trials) related eating disorder syndromes.
Other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term. Self-help approaches that used highly structured CBT treatment manuals were promising. Exposure and Response Prevention did not enhance the efficacy of CBT.
Psychotherapy alone is unlikely to reduce or change body weight in people with bulimia nervosa or similar eating disorders.
Authors' conclusions
There is a small body of evidence for the efficacy of CBT in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More and larger trials are needed, particularly for binge eating disorder and other EDNOS syndromes. There is a need to develop more efficacious therapies for those with both a weight and an eating disorder.

TL;DR: The serological and molecular techniques are used as an auxiliary tool for the diagnosis and/or for species identification, although the isolation and the identification of Sporothrix spp.
Abstract: In the late 90's there was a change in both the route of transmission and the people at risk for sporotrichosis. This zoonotic cat-man alternative transmission route elicited changes in strategies to control the epidemic. There was a progressive increase in the number of cases involving especially children and the elderly. In addition to becoming hyperendemic, uncommon clinical pictures like immunoreactive clinical presentations or severe systemic cases have emerged. New species were identified and classified through molecular tools using more virulent clinical isolates, like S. brasiliensis, compared to the environmental isolates. Likewise, different species of Sporothrix have been associated with different geographic regions. The serological and molecular techniques are used as an auxiliary tool for the diagnosis and/or for species identification, although the isolation and the identification of Sporothrix spp. in clinical specimen is still the gold standard. Currently sporotrichosis epidemics requires the knowledge of the epidemiological-molecular profile to control the disease and the specific treatment. Itraconazole, potassium iodide, terfinafine, and amphotericin B are the available drugs in Brazil to treat sporotrichosis. The drug of choice, its posology, and treatment duration vary according to the clinical presentation, the Sporothrix species, and host immune status. New treatment choices, including a vaccine, are being developed; nevertheless, more clinical trials are required to confirm its efficacy.

TL;DR: There is increasing evidence for a correlation of these cytokines with progressive disease, and several Leishmania antigens implicated in protective immune responses seem also likely to be involved in resistance to visceral leishmaniasis.
Abstract: The role of dogs as the main reservoir of visceral leishmaniasis has led to an increased interest in the immune responses and in Leishmania antigens implicated in protective cellular immunity in canine visceral leishmaniasis. The primary goal is to control the prevalence of human disease. Immune responses in canine visceral leishmaniasis are reviewed. Cellular immune responses toward a Th1 subset mediated by IFN-gamma and TNF-alpha predominate in asymptomatic dogs exhibiting apparent resistance to visceral leishmaniasis. On the other hand, while the role of Th2 cytokines, such as IL-4 and IL-10, in symptomatic animals is still controversial, there is increasing evidence for a correlation of these cytokines with progressive disease. CD8+ cytotoxic T cells seem also likely to be involved in resistance to visceral leishmaniasis. Several Leishmania antigens implicated in protective immune responses are described and some pivotal points for development of an effective vaccine against canine visceral leishmaniasis are discussed.

TL;DR: False detection of carbapenemase production was observed by the MHT possibly as a result of extended-spectrum beta-lactamase (ESBL) production coupled with porin loss as reported before.
Abstract: Objectives The aim of this study was to evaluate the presence of carbapenemases in a Klebsiella pneumoniae collection and the performance of the modified Hodge test (MHT) to correctly identify this phenotype. Methods Twenty-eight K. pneumoniae clinical isolates with reduced susceptibility to carbapenems were evaluated. Antimicrobial susceptibility and molecular typing were performed by agar dilution and PFGE, respectively. The MHT was performed using both standard and high inoculum of test organisms. Imipenem hydrolysis was investigated by spectrophotometric assays and carbapenemase-encoding genes were identified by PCR and amplicon sequencing. Porin loss was investigated by both PCR and SDS-PAGE. Results Susceptibility rates for imipenem, meropenem and ertapenem were 93%, 57% and 11%, respectively. The PFGE analysis showed seven unrelated genotypes. By testing standard inoculum and ertapenem or meropenem discs, 25% (n = 7) and 21% (n = 6) of the isolates were classified as carbapenemase producers, respectively. When a higher inoculum was employed, these rates increased to 54% (n = 15) and 43% (n = 12), respectively. No imipenem hydrolysis was detected. PCRs identified bla(CTX-M) in 27 (96%) isolates, of which 2 isolates also carried bla(GES-1.) SDS-PAGE and PCR assays revealed that all isolates had lost at least one outer membrane protein, except for a single isolate that was found to express both OmpK35 and OmpK36. Conclusions False detection of carbapenemase production was observed by the MHT possibly as a result of extended-spectrum beta-lactamase (ESBL) production coupled with porin loss as reported before. Clinical laboratories must be aware of this fact, especially in geographical areas where ESBL-producing isolates are highly prevalent.

TL;DR: It is shown for the first time that VAPB protein levels are reduced in ALS8-derived motor neurons but, in contrast to over-expression systems, cytoplasmic aggregates could not be identified.
Abstract: Amyotrophic lateral sclerosis (ALS) is an incurable neuromuscular disease that leads to a profound loss of life quality and premature death. Around 10% of the cases are inherited and ALS8 is an autosomal dominant form of familial ALS caused by mutations in the vamp-associated protein B/C (VAPB) gene. The VAPB protein is involved in many cellular processes and it likely contributes to the pathogenesis of other forms of ALS besides ALS8. A number of successful drug tests in ALS animal models could not be translated to humans underscoring the need for novel approaches. The induced pluripotent stem cells (iPSC) technology brings new hope, since it can be used to model and investigate diseases in vitro. Here we present an additional tool to study ALS based on ALS8-iPSC. Fibroblasts from ALS8 patients and their non-carrier siblings were successfully reprogrammed to a pluripotent state and differentiated into motor neurons. We show for the first time that VAPB protein levels are reduced in ALS8-derived motor neurons but, in contrast to over-expression systems, cytoplasmic aggregates could not be identified. Our results suggest that optimal levels of VAPB may play a central role in the pathogenesis of ALS8, in agreement with the observed reduction of VAPB in sporadic ALS.
