We read with interest the paper by Van de Velde et al delineating the concept of self-management in chronic conditions.1 We agree that there is a lack of consensus on the meaning of self-management, ambiguity regarding the concept, and an urgent need for uniformity with regard to terminology. One major area of ambiguity is the relationship between self-management and self-care. These terms are often thought of as synonyms, used interchangeably, or considered as integrated concepts (e.g. self-care as an overarching or umbrella term, with self-management as onecomponent of self-care).2 This is why, until 2018, major search engines combined the terms. When one searched for “self-management”, literature on “self-care” was provided as well. Since Van de Velde and co-workers aimed to delineate the concept of self-management and develop a definition for its use in healthcare, we expected a more thorough review of related concepts in their concept analysis. Thus, we were surprised to find that several important publications on self-care were excluded.
We believe that the concept analysis by van de Velde et al would have been stronger if they also had included publications related to self-care. In 2012, after many years studying self-care in heart failure, we developed the Middle-Range Theory of Self-Care of Chronic Illness,3 which was updated this year.4 In this theory we defined self-care as the process of “maintaining health through health promoting practices and managi...

We believe that the concept analysis by van de Velde et al would have been stronger if they also had included publications related to self-care. In 2012, after many years studying self-care in heart failure, we developed the Middle-Range Theory of Self-Care of Chronic Illness,3 which was updated this year.4 In this theory we defined self-care as the process of “maintaining health through health promoting practices and managing illnesses” (p. 195),3 a definition quite similar to the definition provided for self-management. Since publication, investigators around the globe have used our theory to study how individuals maintain their health, monitor and manage their illnesses. But even before the official publication of the Middle-Range Theory of Self-Care of Chronic Illness, there was a wealth of publications studying self-care that might have been included in the present concept analysis.
We agree with the authors that self-management, or self-care, is important for the sustainability of our healthcare systems into the future. Discussions aimed at reaching consensus on shared terminology can only benefit society and the development of the science. So, we thank you for your efforts to examine “self-management” and hope that you will do the same for “self-care”. Such an effort to compare and contrast the two common terms would be a major contribution to our shared goal of consensus.

Thank you for your recent BMJ Open article,1 which has correctly noted that it is critical for journal editors’ potential conflicts of interest to be publicly disclosed. A limitation of the study is that only the digital version of the journals were considered. Obstetrics & Gynecology has included a conflict of interest statement for the Editor-in-Chief and Deputy or Associate Editors on the masthead of the print journal since the July 2008 issue. The article by Dal-Ré has prompted us to review our digital presence, and the website has since been updated to reflect our long-standing presentation of the editors’ potential conflicts of interest. I thank the authors for highlighting the importance of disclosing potential conflicts of interest but express concern that their work is biased toward the digital presence only.

While it is important for medical students, along with those that teach them, to know how to communicate appropriately with their clients of all sizes, a simulation such as a fat suit is NEVER an accurate substitute for speaking with a client that lives every day with a fat body. Unless the person wearing a fat suit has lived with the stigma, discrimination and overt hatred of their body by a medical professional, their is no way the communication/conversation about their bodies will be the same.

We recently reported no increase in any brain tumour histological type or glioma location between 1982 and 2013 in Australia that can be attributed to the use of mobile phones1. Our analysis included brain tumour incidence in adults aged 20–59 years but Phillips2 criticised this age-range mentioning that it was inappropriate not to include the 60+ age group which has the highest incidence of brain tumours. In a response to Phillips3, we reiterated that the age-range in our study was chosen in order to compare our results with the Interphone study4. We further mentioned that including cases older than 60 would be more affected by improvements in diagnosis and their inclusion would reduce the chance of assessing mobile phone related changes to tumour incidence.
As a follow up to our original analysis, we investigated the incidence trends of brain tumour histological types and anatomical location in Australians aged 60+ diagnosed between 1982 and 2013. The methods of our follow up analysis were the same as our original study1 and the observed incidence trends, given as annual percentage change (APC) and 95% confidence limits, were examined over the time periods 1982–1992, 1993–2002 and 2003–2013 (representing increased CT and MRI use, advances in MRI and substantial and increasing mobile phone use, respectively).

As a follow up to our original analysis, we investigated the incidence trends of brain tumour histological types and anatomical location in Australians aged 60+ diagnosed between 1982 and 2013. The methods of our follow up analysis were the same as our original study1 and the observed incidence trends, given as annual percentage change (APC) and 95% confidence limits, were examined over the time periods 1982–1992, 1993–2002 and 2003–2013 (representing increased CT and MRI use, advances in MRI and substantial and increasing mobile phone use, respectively).
There was a total of 20300 eligible brain cancer cases aged 60+ that were diagnosed between 1982 and 2013. The observed incidence trends for glioma were: 3.62 (2.60 – 4.65) during 1982–1992; 0.96 (0.03 – 1.91) during 1993–2002; and 0.30 (-0.41 – 1.02) during 2003–2013. Specifically for glioblastoma the incidence trends were 5.18 (3.75 - 6.63), 2.57 (1.43 - 3.72) and 1.28 (0.47 - 2.10) for the three time periods, respectively. Thus there were substantial and significant increases in the first two periods, concordant with diagnostic improvements, and much smaller or no trend in the third period.
There were decreasing trends in the 60+ age group for brain tumours with unspecified histology during the periods of increased and more precise diagnosis i.e. during 1982–1992 and 1993-2002. With the redistribution of unspecified tumours as was performed in our original study, there were no significant changes to the histological trends.
It has been previously reported that the temporal and parietal lobes are more highly exposed to radiofrequency radiation than other brain sites when using a mobile phone5. In the analysis of glioma location of the 60+ age group the incidence trends for the temporal lobe were 10.07 (6.95 - 13.28), 3.93 (1.77 - 6.15) and 3.25 (1.76 - 4.77) for the three time periods, respectively. Specifically in the last period there were 1912 cases of temporal lobe glioma. With the redistribution of a high number of gliomas with unspecified and overlapping location there was a much lower trend for gliomas on the temporal lobe during the period of substantial mobile phone use i.e. 1.69 (0.16 – 3.23) during 2003–2013. Therefore, no significant increased incidence was observed for gliomas of the temporal lobe after accounting for the unspecified tumour locations. For the parietal lobe the incidence trends were 10.07 (7.49 - 12.72), -3.26 (-5.30 – (-1.17)), and -1.28 (-3.07 - 0.55) for the three time periods, respectively. With the redistribution of gliomas with unspecified and overlapping location the trend for parietal lobe tumours decreased further during the period of substantial mobile phone use i.e. -2.58 (-4.16 – (-0.98)).
We also compared the observed incidence of the 60+ age group during the period of substantial mobile phone use (2003–2013) with predicted (modelled) incidence for the same period by assuming a causal association between mobile phone use and glioma (with varying relative risks ranging from 1.5 – 3). Similar to our original results for the 20-59 age group, the predicted incidence rates for the 60+ age group were higher than the observed rates for latency periods up to 15 years.
The pattern of these results is consistent with increased and more precise diagnosis, especially during 1982-1992 and also during 1993-2002. In the last period (2003-2013) there were very small increases in glioblastoma and gliomas of the temporal lobe in the 60+ age group which were most likely due continuing improvements in diagnosis and classification. We maintain that the age range used in our original study was the most appropriate for investigating mobile phone related changes to tumour incidence.

This paper is interesting and a welcome addition to the literature. The authors discuss the potential issues related to the use patient post codes. The case of the New Forest, considered a hot spot, is interesting in this regard. The number of residents currently is 38,000 and the annual number of visitors is 13.5 million according to the New Forest District Council.
In their recent paper, exploring prognostic signs and symptoms in relation to survival of 72 hours, White N, Reid F, Harries P, et al. (BMJ Open 2019), mention that a ‘large portion of data was unavailable, particularly that relating to the psychological and spiritual well-being of the patient, due to the decreased consciousness of the patient.’ This comment highlights, in my experience, the absence of documented information about a patient’s psychological and spiritual well-being prior to the final days of life. For some patients, an important aspect of spiritual well-being is religious faith, including the support of a faith community and the opportunity to receive end-of-life religious rites.
When patients are admitted for end-of-life care, there can be occasions when there is little or no time for an in-patient team to learn about a person’s spiritual or religious needs. This may be due to the fact that a patient is unconscious on admission and there are no accompanying relatives or friends. In such situations, the referral form is crucial. Yet, the pan-London Specialist Palliative Care (SPC) Community and SPC Inpatient Unit Referral Form does not provide a specific ‘religion’ box.

This form does have a section for ‘any other comments/information (including preferences expressed about care, other psychosocial or spiritual issues or DOLS)’, but almost invariably the referrer fails to mention spiritual or religious needs. Clearly, it is important to know if the patient has a religious faith as, for example, a Catholic patient may need to be anointed with some urgency, and a Muslim or Jewish patient may need to be buried within strict timelines. Acknowledging and ensuring that a patient’s religious needs are met, as part of end-of-life care, may contribute to the spiritual well-being not only of the patient but also of the immediate family.

In contrast with prior literature - which only focused on a limited number of specialties - HJ Vaidya et al (1) demonstrated that medical students who have a longer placement period in a particular speciality are no more likely to pursue a career in that speciality. The study has important implications, and the authors should be commended, as it suggests that increasing exposure to clinical specialties during medical school will not solve current recruitment pressures.
Interestingly, the authors chose to incorporate specialties such as clinical radiology and public health within the statistical analysis. However we question the reliability of the subsequent results, given the small number of medical schools that offered placements in those specialities.
By using the number of weeks allocated to a particular speciality by each medical school, the authors created a useful, objective metric that could be used for statistical analysis. However, upon reading, we noted that it may not wholly reflect a student’s exposure to that speciality during their placement. In our experience as medical students, we feel that due consideration must be given to the quality of a clinical placement as well as it’s duration. The hospital in which a student is based, the medical team that they shadow, and the student’s experience are but some of the factors that may influence the degree of a student’s involvement on a particular firm, thereby influencing their e...

In our experience as medical students, we feel that due consideration must be given to the quality of a clinical placement as well as it’s duration. The hospital in which a student is based, the medical team that they shadow, and the student’s experience are but some of the factors that may influence the degree of a student’s involvement on a particular firm, thereby influencing their exposure to the speciality. It also allows positive relationships to develop between the trainee and mentor – a feature that should be further exploited in undergraduate education (2).
It is likely that exposure to a speciality is an important, but not the deciding factor, in determining career choice. Take for example students looking to enter a career in surgery. There is an increased cost for surgical training through regular attendance of surgical training courses and conferences, and undertaking higher degrees to increase the likelihood of obtaining competitive posts. Additionally, membership and medical defence fees often leads to surgical trainees having to spend over £130,000 in total (3). Many would also perceive surgery as being a more stressful specialty and this can deter students who are looking for a better work-life balance (4).
Based on this study and prior literature, it may be beneficial for future studies to combine the use of subjective measures and objective metrics to define the quality and quantity of exposure to a particular speciality, as well as surveys to understand the ultimate reasons for final career choices. Additionally, it would be interesting to see the effects of foundation year placements on future career choices.

Léguillier commented on the methodological biases in our recent study. We thank Léguillier for his interest and here we provide further clarification of the points mentioned in his letter.
Firstly we would like to clarify that the two handheld analysers used: Nova StatStrip Xpress Lactate Meter (Nova Biomedical, Waltham, USA) and Lactate Scout+ (EKF Diagnostics, Leipzig, Germany), were both calibrated, maintained and tested for quality control by their respective companies. In the absence of prior evidence of the superiority of one make of machine over another, we chose to compare two standard models.
Regarding the comment on the sample size, the calculated sample size using Bland-Altman method[1,2] was directed at the primary outcome measure, which was the agreement of the capillary blood lactate level measured by handheld lactate analyser when compared with the reference standard technique. Due to the diverse spectrum of patients seen in the ED, the range of lactate levels was representative of our daily clinical practice and was thus pragmatic. Furthermore, our sample size of 240 was larger than previous studies [3-7] ranging from 24 to 120 patients.
Lastly, we chose to use a cut off of 2 mmol/L as this is the upper limit of a normal lactate value. As we mentioned in the paper, screening ED venous lactate levels using a handheld analyser could provide information to shorten the time to identify patients at risk and to allow rap...

I commend the authors for developing and validating this proficiency-based progression training. Epidural failures have a significant impact on patient satisfaction and at times patient safety on labor and delivery. The reduction in epidural failure realized through this program is impressive. I wonder if the authors could provide information on each trainees epidural failure rate. There is significant variance in the number of epidural placements that it takes for a trainee to achieve competence. I worry that one or two trainees in the simulation-only group with very high rates of epidural failure may have biased the results significantly. Seeing the epidural failure rates for each individual trainee would address this concern.

Dear Editor,
In contrast with prior literature - which only focused on a limited number of specialties - HJ Vaidya et al (1) demonstrated that medical students who have a longer placement period in a particular speciality are no more likely to pursue a career in that speciality. The study has important implications, and the authors should be commended, as it suggests that increasing exposure to clinical specialties during medical school will not solve current recruitment pressures.
Interestingly, the authors chose to incorporate specialties such as clinical radiology and public health within the statistical analysis. However we question the reliability of the subsequent results, given the small number of medical schools that offered placements in those specialities.
By using the number of weeks allocated to a particular speciality by each medical school, the authors created a useful, objective metric that could be used for statistical analysis. However, upon reading, we noted that it may not wholly reflect a student’s exposure to that speciality during their placement. In our experience as medical students, we feel that due consideration must be given to the quality of a clinical placement as well as it’s duration. The hospital in which a student is based, the medical team that they shadow, and the student’s experience are but some of the factors that may influence the degree of a student’s involvement on a particular firm, thereby influencing their e...
Show MoreDear Editor,
Léguillier commented on the methodological biases in our recent study. We thank Léguillier for his interest and here we provide further clarification of the points mentioned in his letter.
Firstly we would like to clarify that the two handheld analysers used: Nova StatStrip Xpress Lactate Meter (Nova Biomedical, Waltham, USA) and Lactate Scout+ (EKF Diagnostics, Leipzig, Germany), were both calibrated, maintained and tested for quality control by their respective companies. In the absence of prior evidence of the superiority of one make of machine over another, we chose to compare two standard models.
Regarding the comment on the sample size, the calculated sample size using Bland-Altman method[1,2] was directed at the primary outcome measure, which was the agreement of the capillary blood lactate level measured by handheld lactate analyser when compared with the reference standard technique. Due to the diverse spectrum of patients seen in the ED, the range of lactate levels was representative of our daily clinical practice and was thus pragmatic. Furthermore, our sample size of 240 was larger than previous studies [3-7] ranging from 24 to 120 patients.
Lastly, we chose to use a cut off of 2 mmol/L as this is the upper limit of a normal lactate value. As we mentioned in the paper, screening ED venous lactate levels using a handheld analyser could provide information to shorten the time to identify patients at risk and to allow rap...
Show MoreI commend the authors for developing and validating this proficiency-based progression training. Epidural failures have a significant impact on patient satisfaction and at times patient safety on labor and delivery. The reduction in epidural failure realized through this program is impressive. I wonder if the authors could provide information on each trainees epidural failure rate. There is significant variance in the number of epidural placements that it takes for a trainee to achieve competence. I worry that one or two trainees in the simulation-only group with very high rates of epidural failure may have biased the results significantly. Seeing the epidural failure rates for each individual trainee would address this concern.
