Smoking Cessation: A Paradise for an Alternative to Evidence-based Medicine?
Tahiri et al concluded that acupuncture and hypnosis may help people quit smoking. They used the Cochrane assessment tool to assess the quality of included randomized controlled trials for their meta-analysis, but their conclusion differs from 2 recent Cochrane systematic reviews: “There is no consistent evidence that acupuncture (and the related intervention acupressure, laser therapy, or electrostimulation) and hypnotherapy are effective for smoking cessation.”

Thank you for the letter regarding our article entitled “A New Disease: Bicuspid Aortic Valve Aortopathy Syndrome.” I agree with your assertion that this congenital disease entity is not uncommon and appreciate your clarification of the prevalence of approximately 1 in 50 (up to 2%) of the general population. The motivation for our report was to introduce this potentially unheard-of association between a seemingly innocent common congenital aortic valve abnormality with its lesser known associated and potentially deadly counterpart of aortic pathology.

Bicuspid Aortic Valve Aortopathy Syndrome: A Potentially Familiar Disease
We read with great interest the editorial by Sorrell et al on bicuspid aortic valves and aortic disorders, which was recently published in the Journal. It is important to highlight the relevance of this congenital disease, prevalent among 0.5% to 2% of the population, and its association with other congenital defects, ascending aortic aneurysm, and the risk of aortic dissection, as well as its probable hereditary or familial pattern present in 10% to 30% of bicuspid aortic valve cases.

Frontiers of Therapy for Patients With Heart Failure
Abstract: This review broadly covers advances in heart failure, which is responsible for significant morbidity, mortality, and cost in the United States. It is a heterogeneous condition, and accurate classification helps ensure appropriate application of evidence-based therapies. Hemodynamics are important in acute heart failure syndromes and may help tailor therapy. Neurohormonal modulation forms the cornerstone of chronic systolic heart failure treatment but does not affect outcomes in diastolic heart failure where management goals emphasize optimization of central volume, blood pressure, and atrial rhythm, as well as t...

Protecting intellectual property associated with Canadian academic clinical trials - approaches and impact
Intellectual property is associated with the creative work needed to design clinical trials. Two approaches have developed to protect the intellectual property associated with multicentre trial protocols prior to site initiation.The 'open access' approach involves publishing the protocol, permitting easy access to the complete protocol. The main advantages of the open access approach are that the protocol is freely available to all stakeholders, permitting them to discuss the protocol widely with colleagues, assess the quality and rigour of the protocol, determine the feasibility of conducting the trial at their centre, an...

A Text Messaging-Based Smoking Cessation Program for Adult Smokers: Randomized Controlled Trial
Conclusions: Although the study was not powered to detect statistically significant differences, as the primary aim was to provide estimates of effect size that could be used to better inform a power analysis for a larger trial, findings provide optimism that SMS Turkey may be able to affect quitting rates in environments with high smoking prevalence, such as Ankara, Turkey.

Increasing ciprofloxacin resistance of isolates from infected urines of a cross-section of patients in Karachi
Conclusions: A decrease in bacterial susceptibility of uropathogens to ciprofloxacin, a commonly prescribed drug in our population, is underlined, occurring possibly due to overuse pressure. Empirical initial treatment with ciprofloxacin would be inadequate in more than half of UTI cases, thereby counseling increased C/S testing of urines to provide existing sensitivity data for apt drug prescription.

Adaptive evolution by recombination is not associated with increased mutation rates in Maize streak virus
Conclusions: While our results suggest that recombination does not strongly influence mutation rates in MSV, they indicate that high geminivirus mutation rates are at least partially attributable to increased susceptibility of all geminivirus genomes to oxidative damage while in a single stranded state.

Non-local competition drives both rapid divergence and prolonged stasis in a model of speciation in populations with degenerate resource consumption
The theory of speciation is dominated by adaptationist thinking, with less attention to mechanisms that do not affect species adaptation. Degeneracy -- the imperfect specificity of interactions between diverse elements of biological systems and their environments -- is key to the adaptability of populations. A mathematical model was explored in which population and resource were distributed one-dimensionally according to trait value. Resource consumption was degenerate -- neither strictly location-specific nor location-independent. As a result, the competition for resources among the elements of the population was non-loca...

Imaging joints for calcium pyrophosphate crystal deposition: a knock to the knees
With advanced age, articular calcium pyrophosphate crystal deposition (CPPD) is common. Defining who has CPPD is of growing importance, given increases in longevity in many countries and the frequent association of chondrocalcinosis with osteoarthritis. Chondrocalcinosis detected by plain radiography serves as a major screening tool, but how many and which sites to screen have not been adequately defined in the past. The work of Abhishek and colleagues in the previous issue of Arthritis Research and Therapy sheds new light on the incomplete information from knee radiographs, and helps position us to learn more about the ep...

Inflammatory lesions in the bone marrow of rheumatoid arthritis patients: a morphological perspective
The synovial tissue stands at the epicenter of joint pathology in rheumatoid arthritis (RA). As a primary target of the disease, studies on the synovium have provided invaluable insights into the mechanisms involved in disease pathogenesis. Recent work has, however, revealed the importance of a previously unseen anatomic compartment in direct contact with the joint space, namely the subchondral bone marrow. Bone marrow edema (BME) visible on magnetic resonance imaging (MRI) is clinically meaningful in both early and late RA as it associates with future development of bone erosions and poor functional outcomes. Although the...

Interleukin-27: a potential new sepsis biomarker exposed through genome-wide transcriptional profiling
Sepsis is a complex clinical condition that is driven predominantly by deviations from the orderly stereotypic immunological response to infection. Much effort has been undertaken in the search for biomarkers that can assist in discriminating critically ill patients with sterile inflammation from those with sepsis. Such biomarkers may aid the clinician in therapeutic decision making upon admission of a patient. Interleukin-27 may be such a discriminative biomarker, as suggested in the previous issue of Critical Care by a study of critically ill children.

[Anesthesia in the elderly.]
Abstract A growing number of old or very old patients benefits from a surgical procedure. Age is an independent risk factor of postoperative mortality and postoperative complications including cognitive dysfunction. The choice of anesthetic technique does not significantly modify this risk. Preventive strategies and preoperative procedures can be implemented. A multidisciplinary management involving all care providers around the patient is essential to reduce the risk of dependence after surgery which is higher in this population. Early postoperative rehabilitation is recommended in the elderly to improve the progn...

Capnocytophaga canimorsus infection presenting with complete splenic infarction and thrombotic thrombocytopenic purpura: a case report
Conclusion: There is a common misconception amongst practitioners that the presence of systemic infection excludes the possibility of TTP and vice versa. This case emphasizes that TTP may occur secondary to a systemic infection, thereby allowing the two processes to coexist. It is important to maintain a wide differential when considering the diagnosis of either TTP or C. canimorsus infection since delays in treatment may have fatal consequences.

Evolution of cichlid vision via trans-regulatory divergence
Conclusions: Combined with previous work, we demonstrate that the evolution of cichlid color vision results from the interplay of structural, cis-, and especially trans-regulatory loci. Although there are numerous examples of structural and cis-regulatory mutations that contribute to phenotypic evolution, our results suggest that trans-regulatory mutations could contribute to phenotypic divergence more commonly than previously expected, especially in systems like color vision, where compensatory changes in the expression of multiple genes are required in order to produce functional phenotypes.

Polyphasic characterization and genetic relatedness of low-virulence and virulent Listeria monocytogenes isolates
Conclusions: Loss of virulence in lineage II strains was related to point mutation in a few virulence genes (prfA, inlA, inlB, plcA). These strains thus form a tightly clustered, monophyletic group with limited diversity. In contrast, low-virulence strains of lineage I were more dispersed among the virulence strains and the origin of their loss of virulence has not been identified yet, even if some strains exhibited different mutations in prfA or inlA.

Assessment of psychiatric changes in C9ORF72 frontotemporal dementia
Recent neuroimaging evidence highlights cerebellar atrophy as one feature of frontotemporal dementia (FTD) with C9ORF72 mutation. Interestingly, C9ORF72 patients do not present with classic cerebellar symptoms, such as ataxia but have instead a higher incidence of psychiatric changes compared to sporadic FTD. To date there exists no objective tool to assess such psychiatric changes due to cerebellar dysfunction. In the current edition of Alzheimer's Research & Treatment, Downey and colleagues present a novel task and apparatus which targets such psychiatric disturbances. In the task participants are required to make self-o...

Cost-effectiveness of a health-social partnership transitional program for post-discharge medical patients
Conclusions: Previous studies on transitional care focused mainly on clinical outcomes and not too many included cost as an outcome measure. Studies examining the cost-effectiveness of the post-discharge support services are scanty. This study is the first to examine the cost-effectiveness of a transitional care program that used nurse-led services participated by volunteers. Results have shown that a health-social partnership transitional care program is cost-effective in reducing healthcare costs and attaining QALY gains. Economic evaluation helps to inform funders and guide decisions for the effective use of competing healthcare resources.

[MicroRNAs and their role in hematological malignant diseases].
Abstract MicroRNAs are a class of small non-coding RNAs regulating gene expression at posttranscriptional level. Their target genes include numerous regulators of cell cycle, cell proliferation as well as apoptosis. Therefore, they are implicated in the initiation and progression of cancer, tissue invasion and metastasis formation as well. MicroRNA profiles supply much information about both the origin and the differentiation state of tumours. MicroRNAs also have a key role during haemopoiesis. An altered expression level of those have often been observed in different types of leukemia. There are successful attempt...

Abstract Parkinson's disease is one of the most frequent progressive degenerative disorders with unknown origin of the nervous system. The commutation of the disease on Guam led to the discovery of a neurotoxin which was also found in other continents. This neurotoxin was identified in the common cyanobacteria (blue-green algae). Early clinical observations suggested some loose correlations with gastric and duodenal ulcer and Parkinson's disease, while recent studies revealed a toxin, almost identical to that found in cyanobacteria in one strain of Helicobacter pylori, which proved to cause Parkinson like symptoms ...

[Connections between apolipoprotein E genotypes and the development of cardiovascular diseases].
Abstract Elevated plasma lipid level is one of the main risk factors for cardiovascular diseases, which are considered to be pimary causes of death. Apolipoprotein E plays a part in the lipid transport in the blood, thus polimophisms of that affect the lipid composition of the plasma. The three most common alleles of apolipoprotein E are e2, e3, e4. Out of the two non-wild type alleles, the e2 and e4, the latter was shown to play a role in the development of cardiovascular diseases and Alzheimer's disease. Some studies mention the e2/e2 homozygote genotype as one of the causes of hyperlipoproteinemia type III. Besi...

Assessing research impact in academic clinical medicine: a study using Research Excellence Framework pilot impact indicators
Conclusions: While the 2010 pilot exercise has confirmed that the majority of the proposed indicators have some validity, there are significant challenges in operationalising and measuring these indicators reliably, as well as in comparing evidence of research impact across different cases in a standardised manner. It is suggested that the public funding agencies, medical research charities, universities, and the wider medical research community work together to develop more robust methodologies for capturing and describing impact, including more valid and reliable impact indicators.

L-glutamate released from activated microglia downregulates astrocytic L-glutamate transporter expression in neuroinflammation: the 'collusion' hypothesis for increased extracellular L-glutamate concentration in neuroinflammation
Conclusions: Our findings suggest that activated microglia trigger the elevation of extracellular L-Glu through their own release of L-Glu, and astrocyte L-Glu transporters are downregulated as a result of the elevation of astrocytic intracellular L-Glu levels, causing a further increase of extracellular L-Glu. Our data suggest the new hypothesis that activated microglia collude with astrocytes to cause the elevation of extracellular L-Glu in the early stages of neuroinflammation.

Abstract The acute coronary syndrome is the most severe form of coronary artery disease. It is an immediate threat of life and the mortality rate can be high without proper therapy and patient management. Based on the first ECG, two different forms can be distinguished: acute coronary syndrome with and without ST elevation. Besides adequate medication, management of these patients is an essential part of treatment. In case of ST elevation, coronarography and percutaneous coronary intervention is needed in general, within 24 hours from the onset of symptoms. When ST elevation is not detected on the ECG, individual i...
