  • Obesity among Nurses

    There is no mention of nurses ordering take out and all hours of the day and those choices. Plus many bring in food items from home to share with others. How often does that happen and what is brought .
    Blaming the food service is a quick and easy way to blame others versus choices made by nurses.

  • Using Left over Funding in Applied Research in China Is Illegal

    Dear editor,

    As point of Dr. Atif A Baig, this should not be ethical issue but a legal one. After suitable statement of conflict of interest, it is must be no issue. However, Dr. Atif A Baig's conclusion may be obtained without understanding the regulations in China's National Natural Science Foundation (NNSF).

    The newest China's NNSF funded project funding regulation, see http://www.nsfc.gov.cn/publish/portal0/tab229/info48335.htm, has been taken effect in 2015 and now is running. There are clear rules for usage of left over funding in its article 28. First, the left over funding should be returned to NNSF of China in 2 years after the project has been closed. Second, the left over funding can only be used in direct expenditure of basic research. Moreover, article 37 also said that misappropriation of funding is illegal.

    As common sense of scientific research, there are many differences between basic research and applied research, see 1953's annual report of National Science Foundation of US, https://www.nsf.gov/pubs/1953/annualreports/ar_1953_sec6.pdf. In China, the definition of basic research is similar, see http://www.most.gov.cn/kjgh/kjfzgh/200708/t20070824_52690.htm.

  • Re: Not a random sample

    Dear Dr Peter,
    Thank you so much for your interest and comment.
    The study population consisted of both new pregnant women and those on follow-up of antenatal care clinic (ANC). Yes, it appears that new pregnant women attended ANC in random order. However, pregnant women who were on ANC follow-up visited the clinic on their schedule date. Thus, we assumed there was some pattern to their attendance of the clinic. In order to increase the chance of including women from different schedule dates and avoid clustered selection, we preferred to use a systematic random sampling than convenient sampling.
    Best,
    Techalew

  • Role of Ethical and Legal Funding Implications’ from Funding Agencies

    Dear Editor of BMJ.

    I was reading it all and I assume that many times the issues can’t be ethical but are still legal. Being a neutral moiety, I assume just based on a fact to get justification from author or anyone sending a response is not enough for such serious ethical concerns. There is a serious need to look into the legal implications of use of funding. As per usual practice, the report of all grants are submitted to the funding bodies and if the “authors” have explained and mentioned the use of this all funding or “left over funding” in specific time to be used later as per rules and regulations, there must be no issue as far as no “conflict of interest “ is there between the authors and the funding agency. Seems it’s a very minor issue but for me it’s a new issue of its type and thank you for a very positive attitude from BMJ Open editor for facilitating science and honesty not in science but the concern minor issues.

  • A study of eCONsult, not of online consultations in general

    This study of 36 practices used a particular system, eCONsult, cannot be taken as indicative of online consultations in general. It is all about how the system works, both the software and within the operational system of the practice.
    The average of 0.9 per practice per day is clearly too low to have significant impact, and that was probably to increase costs.
    One of the practices involved, Concord Medical Practice, changed to askmyGP the following year and increased its uptake by a factor of 15 to around 60 per day (reported at SAPC, July 2017). Others have a similar level. Then the wider impact becomes measurable. Independent study is urgently needed as a £45m fund has been created to fund this technology, while published evidence says it will be wasted.

  • Need of Live Attenuated Vaccine for Innate Immune Response Against Streptococcus pneumoniae; Targeting Netosis based Immune Response

    he role of Neutrophil Extracellular Traps (NETs) in effectively trapping and destroying bacteria during a bacterial infections is a recent discovery. But certain bacterias, eg. Streptococcus Pneumoniae can escape traps by degrading chromatin fibers of NETs by surface exposed receptors and thus results in promoting bacterial spreading through the airway and into the bloodstream. Furthermore, Wartha and colleagues showed that S. pneumoniae evades NETs by a positive charge on its surface as a result of capsule expression and lipoteichoic acid d-alanylation. However, the mechanisms related to S. pneumoniae-induced NET formation remain unclear beside its degradation. The exact molecular mechanism of escaping NETs by S. pneumoniae is needed to be studied as per basic structural component degradation of NETs towards the pathogenesis and immunogenic response of S. pneumoniae against host defense mechanisms. Studying the exact molecular effect on the quantification and structure of NETs in infected neutrophils is expected to define specific pathogenic induction and destruction of NETs under the effect of specific genes in comparison with their mutants as live controls. The resultant mutants are also expected to give high immune response beside helping in understanding the basic mechanism of NETs in respect to specific genes. This could help in targeting the innate immune response at a more broader level beside multivalency of the vaccine will never be an issue.

  • The CLIMB (Complex Lipids In Mothers and Babies) study

    Dear Sir/Madam

    We have been alerted to an error in our paper:

    The text: Our primary objectives are: i) evaluate the impact of maternal dietary CML intake on maternal and infant complex lipid status by comparing outcomes of product A with product B and a reference group and; ii) investigate the benefits of the fortified maternal milk products (containing CML) on maternal health and nutritional status, and general infant health and neurodevelopment.

    Should have read: Our primary objectives are: i) evaluate the impact of maternal dietary CML intake on maternal complex lipid status by comparing outcomes of product A with product B and a reference group and; ii) investigate the benefits of the fortified maternal milk products (containing CML) on maternal health and nutritional status. Secondary outcomes include the effects of the products on infant complex lipid status, and on general infant health and neurodevelopment.

    We would be most grateful if an erratum/correction could be published on line

  • Pelvimetery and vaginal breech delivery

    Dear Sir,

    It was disappointing to read the recent report on vaginal breech delivery in Cameroon.1 Pelvic assessment was performed clinically. Surely the Faculty of Medicine and Biomedical Science at the University of Yaounde 1 has access to radiological facilities for an erect lateral pelvic X-ray?
    Perhaps the academic debate on pelvimetry in more developed countries has clouded the issue for those in Cameroon. If this is so then the developed world has done little for poorer countries in this area of medicine.
    Joyce et al,2 found that for failed vaginal breech delivery there was a linear relation between the Obstetric conjugate dimension and the fetal size.
    A flat sacrum is important especially if the mid-pelvic AP diameter is narrower than the Obstetric conjugate and the Obstetric conjugate is less than 11.7cms.
    Potter et al.3 studied cases of infants who died of intracranial injury after vaginal breech delivery. In 13 cases maternal pelvic radiographs were available in seven and there was diminished pelvic capacity in all. Beischer4 reviewed the outcome of term breech delivery in 64 patients with pelvic contractions as documented by radiographs. Thirteen patients were delivered by caesarean and all infants survived. In the 51 infants vaginally delivered there were four deaths, three of which were due to tentorial tears. Collea et al.5 performed a study of term frank breech delivery. They randomized patients to vaginal or caesarean delivery...

  • Note from the Editor in reference to response from Yuzhen Li

    The editorial team of BMJ Open are currently investigating the issues raised by Yuzhen Li in response to this article.

    We have asked the authors to respond to the points raised and will investigate the case in line with the principles of the Committee On Publication Ethics (COPE).

  • Spurious conclusions from a faulty analysis

    It is to be commended that the article on the effects of economic crises on population health outcomes in Latin America, by. Callum Williams et al., clearly explains the methods the authors used for the analysis. For that reason, the paper is a very good example of how not to use a specific type of research tool, the panel regression. In a panel regression, as in any time-series investigation of causality, a key issue is to adjust for time trends, so that variables are stationary series (1, 2). If this adjustment is missing, results are biased by trends in the variables. For example, the paper says that “after removing inflation and unemployment as controls from our regression analysis, GDP per capita increases were found to be associated with improvements in all mortality metrics.” This is just an spurious result, as in every country the trend in GDP per capita is a rising one and the trend in mortality is a declining one. If you put the number of Starbucks coffee-shops in the country rather than GDP per capita, it will be also associated with “improvements in all mortality metrics” as Starbucks are also increasing in number.
    Lack of adjustment for time trends in the variables in more than sufficient to make the results of the regression spurious, but the models in this paper have another major flaw: both unemployment and GDP per capita are included at the same time as explanatory variables in the models. Callum Williams and coauthors seem unaware that these two var...
