In milk, there is more sugar than fat. With 5 litres of milk, the patient would have ingested about 250g sugar. So could it be that the increase of triglycerides was due to excess sugar intake in a diabetic patient off hid medication?
Pursuant to the study methodology, I would like to comment on the use of a reduced dose of apixaban. As per literature, and according to the authors, a reduced dose of apixaban is recommended if the patient has two of three conditions (Serum creatinine ≥1.5 mg/dL, age ≥80 years of age, or body weight ≤60 kg). The authors mentioned that the patient was eligible to a full dose (5 mg twice daily) based on his age (85 years old) and serum creatinine level (1.38 mg/dl); nevertheless, they decided to use a reduced dose (2.5 mg twice daily) due to impaired renal function despite serum creatinine level did not reach the required threshold for reduction. Until this point, reader may imply that patients with old age (≥80 years of age) can use the reduced dose with similar efficacy for reducing thrombus size even if serum creatinine does not reach the set threshold that is necessary for a reduced dose. However; a major confounder was not mentioned in patient baseline characteristics which is the patient weight. If the patient weight was equal to or less than 60 KG, the patient would have been eligible to a reduced dose, which means that the result of this study would be limited to the use of the recommended dose based on age, weight, and serum creatinine rather than the treating physician discretion. Moreover, there were no referenced studies to support the non-inferiority of the reduced dose of apixaban compared to the standard dose in eligible patients, which si...

I hope that patient weight can be included in the study in order to give readers a better insight.

Dear Editorial Team,
We read this article with great interest as Brexit has clearly created significant stress and impact on everyone’s life in the U.K. This article has also been widely quoted in major Newspapers including The Sun, The Guardian and The Independent creating an interesting debate by portraying a picture that Brexit could cause psychosis. Hence, we wanted to critically appraise this article using Sir Austin Bradford Hill’s Criteria (2).
In 1965, Sir Austin Bradford Hill proposed a set of 9 criteria to provide evidence of a causal relationship between a presumed cause and an observed effect (2). Using his criteria we are able to examine epidemiological studies and factors to understand better how environmental factors relate to health and the advancement of disease.
The development of psychotic disorders is multifactorial, the article itself identifies “that additional work and family related stresses may have contributed” to this patient’s ATPD (1). The...

Dear Editorial Team,
We read this article with great interest as Brexit has clearly created significant stress and impact on everyone’s life in the U.K. This article has also been widely quoted in major Newspapers including The Sun, The Guardian and The Independent creating an interesting debate by portraying a picture that Brexit could cause psychosis. Hence, we wanted to critically appraise this article using Sir Austin Bradford Hill’s Criteria (2).
In 1965, Sir Austin Bradford Hill proposed a set of 9 criteria to provide evidence of a causal relationship between a presumed cause and an observed effect (2). Using his criteria we are able to examine epidemiological studies and factors to understand better how environmental factors relate to health and the advancement of disease.
The development of psychotic disorders is multifactorial, the article itself identifies “that additional work and family related stresses may have contributed” to this patient’s ATPD (1). The author themselves highlight multiple social stressors occurring around the time of presentation, these include losing a court case and family pressures1. If we apply Bradford Hill’s criteria of specificity (2) to this scenario, we cannot be certain that result of the Brexit referendum was the driving factor for this patient’s development of ATPD (1). This is further strengthened by the author stating a similar episode was experienced by the patient “following work related stress, 13 years previously” (1).
To support Bradford Hill’s criteria of reproducibility (2), we would expect that three years following the Brexit referendum, there would be multiple witnessed cases of ATPD precipitated by Brexit, especially in patients who are vulnerable to psychotic episodes. Try as we might to avoid it, Brexit is currently a topic dominating the media and general conversation. Therefore, if we were to apply Bradford Hill’s “biological gradient” criterion which stipulates that a greater exposure generally leads to a greater incidence of the effect, we should be witnessing more reported cases of Brexit-precipitated ATPD. Despite this, the article lists only one other transient psychotic episode precipitated by a political event - a case from the USA - unrelated to Brexit.
We feel that it is a bold statement to imply that Brexit can precipitate an acute and transient psychotic disorder (ATPD) without considering the rules comparing causation and correlation. Brexit might be associated with an acute psychotic episode, and could be an associated symptom of this patient’s psychosis however; conclusion that it might have a causative role may be an arbitrary inference.

We have read this paper; Ahmed Khaldoon Hankir et al. (2014) with great enthusiasm. We are medical students from Kings College London. We are aware that mental health disorders are a serious and widespread problem across medical schools.
Recently, there has been a greater emphasis on mental health in medical students and is currently highest compared to previous years.
Awareness on our campus has been mainstreamed by staff at the university, and events by societies. However, turn out at these events are discernably low, despite being publicised on the same platforms that cater to similar-sized social events. Our experience is that in a setting that is thought to be free from judgement by peers and seniors, students are still reluctant to seek help.
One way to counter this difficulty for Kings College London, and other universities, other courses, would be to introduce a questionnaire to medical students, across the U.K, to find out what they believe are the reasons that they or their peers with mental health problems are reluctant to seek help. We think a practical way of managing this would be to implement a PALS type scheme but catered for students with mental health concerns. This one-on-one type talks can discuss aspects of stress, sleep deprivation, academic struggles that may contribute to their state. This type of help was incredibly helpful for students who had difficulty adjusting to the change in academic pace.

We recommend Kings College London and other universities implement this change. Each student signed up for mental health support be assigned a mentor/buddy, as students need the emotional support now if they are to work in a busy NHS later on.
After a diagnoses of Lipid Pneumonia, there were no samples tested of the eliquid the patient inhaled. Glycerol, or glycerin is an alcohol and cannot cause lipid pneumonia. Although there 'likely' were other ingredients in her cartridge besides VG, without testing there is no way to make a definitive assumption as to the nature of the exogenous inhalant. We do not know the exact etiology without knowing where the EC cartridge was procured from, in what manner it was ingested, how it was processed, or exactly what was in it. With the patient's extensive pulmonary history, we do not know what, if any, other medical issues may have contributed to the final diagnosis. Do we know if the eliquid was accidentally aspirated, if there was a presence of Vitamin E, acetic acid, or even vegetable oil, which is not the same as vegetable glycerin.
In response to this article, I would advise amending these findings to include that "without testing, we cannot conclude a single variable that caused this patient's lipoid pneumonia. More importantly, glycerol is an alcohol therefore could not cause a lipoid pneumonia. Although EC was determined to be the causation of this type of pneumonia, we do not know the exact contents of the liquid. To be noted, the patient did also show bilateral ground-glass opacities that may have contributed to her respiratory failure."
