We really appreciate the comments by Dr Oivind Torkildsen (2) and we thank him for giving us the chance to clarify more on th...

  • Sedentary Behaviour in adults and cardiovascular risk: Letter to editor
    Simran Kaur

    Cardiovascular risk study was carried by Heinonnen et al to establish an association between sedentary lifestyle and cardiovascular risk in young adults. Although due to its cross sectional design, it cannot be extrapolated to address the causality of findings. Nevertheless, it is indeed a good piece of research wherein all confounders except television viewing, which is a growing practice, are accounted for. However, thi...

  • Re:Bed sharing when parents do not smoke: is there a risk of SIDS? An individual level analysis of five major case-control studies
    Paul N Goldwater

    In their paper1 Carpenter et al. conclude that bed-sharing of infants under 3 months with their parents even when the latter did not smoke and had no other risk factors the adjusted odds ratio for SIDS was 5.1 (2.3 to 11.4). This risk was greatly increased when the parents smoked, took alcohol or drugs. These findings are not surprising and confirm that co- sleeping is particularly dangerous for babies under three months of...

  • Inadequate data, too many confounders and a ridiculous analogy!
    Sara L Macbay

    I am appalled that this paper managed to get past peer review and reach publication. The authors define 'breastfed' as 'partially or completely breastfeeding at time of death or interview'. This implies there were babies entered into the breastfed group who were receiving formula in quantities that are unknown. What exactly is partially breastfed? Is this one, two, three bottles of formula per day? One breastfeed per da...

  • Incomplete examinations are irrelevant and all too frequent.
    Edward Archer

    Dear Editor: By design, incomplete examinations provide data that lead to superficial correlations, erroneous inferences, and poor public health policy. Schmidt et al.1, provide an exemplar of this increasingly frequent event. Physical inactivity is a leading cause of death worldwide as well as a principal underlying pathology in most major causes of morbidity and mortality.2 Inactivity affects cardiovascular disease3,4, c...

  • A lack of data and questionable emphasis
    Peter S. Blair

    Dear Editor,

    The report by Carpenter et al [1] on whether there is a risk of SIDS associated with bed sharing when parents do not smoke fails to meet its stated objective because the data needed to resolve any uncertainty is not available from the studies presented. The over-arching argument is whether bed-sharing in itself poses a risk to infants or whether the risk is within the hazardous circumstances in whi...

  • Maternal choice and macrosomia are likely significant contributors to CS rates
    Pauline M Hull

    In the UK, the rate of maternal request caesareans is also higher in private hospitals, and up until November 2011 (when NICE guidance[1] on Caesarean Section changed) maternal request was not on its own supported as an indication for CS in public (NHS) hospitals; therefore many women, who could afford to, paid for their maternal request caesarean privately.

    Unfortunately, despite the fact that NICE guidance now...

  • Re:Maternal age as a confounder
    Kristjana Einarsdottir

    I think you very much for your comment on the article. In response to your comment I have now re-analysed the pre-labour caesarean section rates according to age group, ie for women under the age of 30 and women over 29.

    The separate results for these two age groups showed exactly the same pattern as for the groups combined. For example, the caesarean section rate for women over 29 years of age increased by...

  • Omega-3, omega-6 and vitamin treatment for relapsing-remitting multiple sclerosis
    Oivind Torkildsen

    Dr. Pantzaris and colleagues (1) have recently performed a study on a dietary intervention consisting of omga-3, omega-6 and vitamin A and -E in various formulations in relapsing-remitting multiple sclerosis (RR-MS). The authors suggested that a special combination of omega-3, omega-6 and fat soluble vitamins could have profound effects on magnetic resonance (MR) disease activity and disease progression. The main problem i...
