  • Response to Author's Response to Dr. Pomeroy's Concerns

    Thank you for your response to my concerns and comments on the article. I wish to correct an apparent misunderstanding about concomitant use of SSRIs and stimulants. I did not state that SSRIs have any indication for treating ADHD, I am aware of research to the contrary and have never used SSRIs to treat ADHD. My statement that "SSRIs have FDA-indications for treating both conditions" was intended to refer to the conditions of anxiety and depression; upon re-reading the statement when looking to see how a conclusion was made that I was treating ADHD with SSRIs I can see how it could be mis-construed. Regarding studies of the safety of the combination of stimulants and SSRIs (or other anti-depressants), I also am not aware of any. A prospective study would be challenging to do, to say the least. A retrospective analysis with inclusion of diagnosis-specific information and directly correlating diagnosis, treatment including dosages and duration, and outcomes would probably be challenging as well but I think that degree of detail and specificity is necessary before drawing conclusions about the safety of combinations of medications (drugs) used to treat any condition.
    Thank you again for your careful consideration of my initial comments.
    Respectfully,
    David P. Pomeroy MD
    Regarding my statement that "stimulants and SSRIs are basically safe" I was not contesting the fact that each has Black Box warnings and serious side effects and...

  • Authors’ response to Skafte-Holm et al. (668 words)

    To the editor,

    We are grateful to Axel Skafte-Holm et al. for their careful reading of our systematic review and for highlighting challenges in the classification of Ureaplasma species. We aimed to include studies that identified U. urealyticum or U. parvum using appropriate microbiological methods to examine associations with adverse pregnancy outcomes. For the 14 articles highlighted by Skafte-Holm et al. [1-14], we acknowledge that we used data that the authors of the included studies reported, but which were not consistent with the actual microbiological methods used.
    There is inconsistent reporting of Ureaplasma species owing to changes made to their taxonomy; the resulting misclassification of these species compounds the shortcomings of epidemiological methods of studies in this systematic review. As such, it reinforces our conclusion, that “The currently available literature does not allow conclusions about the role of mycoplasmas in adverse pregnancy and birth outcomes”.
    We updated our analysis of associations between the two Ureaplasma spp. and adverse pregnancy outcomes, following Skafte-Holm and colleagues’ investigations. We removed data from meta-analyses if identification of U. urealyticum was ambiguous and we amended data from studies that identified biovars of Ureaplasma spp. but reported them incorrectly.

    The original systematic review included 57 articles. Of the 14 articles highlighted by Skafte-Holm et al., 10 would remain; 2...

  • Understanding the persistence of open defecation in India: A contesting ground between context and convenience

    The persistent effort towards making India defecation free have met with mixed success that is defining characteristics linked with this adversity and regions with greater failures in this regard. An exercise that uses the most recently obtained data to investigate the correlates of open defecation places the obvious i.e. socio-economic adversity being responsible for this failure. While this phenomenon has a dual bearing of deprivation on one hand and behavioral dimension on the other, a mere provisioning may not translate into changed behavior. But then OD as a practice needs to be read in association with the cultural belief system on ideal hygiene practice and circumstantial convenience. Most enquiries on this subject may well be finding a contesting force between beliefs and practice and convenience together that sustains and justifies OD despite provisioning and promotion of modern sanitary practice. In all these attempts, a variable that perhaps facilitates convenience is the density ( i.e availability of open space) remains overlooked. Owing to inconvenience, it has gained greater success in urban space compared with the rural hinterland. In addition, realization of its success/failure and its geography will also have a systematic connect with population density. Finally, a unidimensional focus on provisioning of sanitation infrastructure may not achieve the dream goal of OD free India rather than it being a part of improving living environment in its entirety that...

  • Risks outweigh the benefits? Myocarditis risk alone appears to exceed the COVID-19 vaccines’ benefits.

    The striking findings by Alami et al., published in The BMJ, that their “meta-analysis indicates that within 30-day follow-up period, vaccinated individuals were twice as likely to develop myo/pericarditis in the absence of SARS-CoV-2 infection compared to unvaccinated individuals, with a rate ratio of 2.05 (95% CI 1.49–2.82)” adds to the recent spate of evidence on the not-so-insignificant risk of COVID-19 vaccine-induced myocarditis.1 For example, Cho et al., publishing in the European Heart Journal, found a COVID vaccine-induced myocarditis incidence rate of around 1 in 100,000, and around 1 in 19,000 for males between the ages of 12 and 17 years; also finding that a significant number of vaccine-induced myocarditis sufferers (around 5%) end up dying soon afterwards.2

    Contrast this with the UK government’s determination of numbers needed to vaccinate to prevent a severe COVID hospitalisation being in the hundreds of thousands for young ‘no risk’ groups.3 It would appear to be an unacceptable risk, at least for certain groups, for this one adverse effect alone. The risk of vaccine-induced myocarditis may indeed be very small, but the risk of serious COVID in the young and healthy is smaller still.

    There are also increasing questions over the vaccines’ effectiveness, such as those concerning statistical biases in observational studies raised in the Journal of Evaluation in Clinical Practice by Fung, Jones, and Doshi;4 and by myself.5 Should we now adm...

  • Reply to “Questioning the superiority of mHealth applications over face-to-face training in treatment adherence among haemodialysis patients”

    Dear authors: Toshinari Kaku, Masahiro Banno and Takahiro Tsuge,
    We are delighted that our article took your attention and we appreciate the time that you spent reviewing our study. We hope the prepared response can solve your concerns.
    First, you mentioned an issue about not implementing face-to-face training properly. As you can see, in the method section, under the participants' headline, we considered not attending the face-to-face training for over three sessions as an exclusion criterion, which means that it was important for us to observe this group closely. No one missed the sessions which means that they were eager to learn and all the participants received the prepared content. Besides, the reason why we designed each session for only about 10 minutes was that the result of previous studies showed long training sessions distract patients’ attention and reduce the outcome. Therefore, we stuck to the mentioned duration to avoid adversely affecting the face-to-face training. Furthermore, in the intervention section, we mentioned that this group was trained by one of the researchers. It means that we directly observed all the participants of this group. There was a chance for the participants of this group to ask their questions by the end of each session while the other group had no access to any source to ask their questions. Moreover, the written training content was handed to the patients of this group to review whenever they wanted.

  • Questioning the superiority of mHealth applications over face-to-face training in treatment adherence among haemodialysis patients

    Abstract: Objective: This article critically examines the study "Comparing the effects of mHealth application based on micro-Learning method and face-to-face training on treatment adherence and perception in haemodialysis patients: A randomised clinical trial" by Mohsen Torabi Khah, Zahra Farsi, and Seyedeh Azam Sajadi. Summary of the argument: There are two concerns that the intervention effect may be overestimated and one that the intervention effect may be underestimated. Conclusion: While the study indicates innovative use of mHealth applications in enhancing treatment adherence, it also highlights potential biases that may have resulted in an overestimation and an underestimation of the intervention's effect.

    Van Rijn et al1 described the implementation and first output data of the Dutch expertise centre for child abuse (LECK: Landelijk Expertise Centrum Kindermishandeling). LECK's methodology aims to be easily accessible for giving anonymous advice when health care professionals suspect potential cases of physical child abuse.1 LECK physicians do not see the patient nor talk to the parents and are neither involved in further treatment or follow-up. LECK works with Bayes' statistics,2,3 and uses likelihood ratios, part of Bayes' theorem, in their conclusions.1

    Bayes' theorem, named after the 18th century English statistician, philosopher and Presbyterian minister Thomas Bayes,2,3 updates the relative probability of an hypothesis (here, physical child abuse caused the symptoms),...

  • Persistent systemic neo-colonialism in academic publication

    Letter to the Editor BMJ Open

    Persistent systemic neo-colonialism in academic publication

    The recent publication of the paper, Clinical emergency care quality indicators in Africa: a scoping review and data summary(1) has triggered much discussion within our network of emergency care academics and clinicians from various countries across Africa.

    The subject matter explored in the publication is crucial, and we would congratulate the authors on tackling this issue. We agree that in many settings of nascent African emergency care systems, it is key to build quality indicators and to use them to improve and measure emergency care. Yet, for a paper that concludes that more needs to be done to improve published work on quality indicators in African emergency care, not including any authors living and working within African emergency care, is a significant oversight.

    The problem of excluding African voices
    Analysing the African emergency care health system from outside Africa is problematic. Africa is not a country, and we find the approach to dealing with Africa as one unit troubling. Although the authors rightly point out that emergency care systems and resources are at profoundly different ends of the spectrum in different settings within the continent, they chose to perform their search looking for evidence from Africa.(1) Much research done within African settings is done without collaboration or active engagement with the African emergenc...

  • Feasibility of Telemonitoring in improving health of tribal’s

    Telemonitoring is an emerging field which uses information technologies to transmit information on patient’s health to the selected healthcare facility. We have read the article by Gijsbers et al al with great interest [1] In addition to these arguments, we would like to express some vital issues regarding the viability of telemonitoring in enhancing triabl health. The effectiveness of telemonitoring in managing health issues was tested in a small number (and very few among tribals) of randomized control trials because it is a new field. These trials found that telemonitoring is beneficial in controlling chronic illness conditions. Telemonitoring has the potential to help with the management of chronic illnesses like hypertension since it enables continuous monitoring of vital signs, which lowers the number of trips to medical facilities [2].
    TASHMINH-4 trial study proved to be a milestone in establishing the effectiveness in the management of Telemonitoring in chronic condition like hypertension. The study done by Richard McManus and colleagues, shows that self-monitoring of blood pressure with Telemonitoring used by general practitioner in poorly controlled individuals has significantly help in improving control over the blood pressure. This study emphasize that self-monitoring of blood pressure by individual helps in better control over of high blood pressure [3][4].
    Telemonitoring provides a platform which makes healthcare services accessible through home...
