Almond as a potential nutritional supplement in patients with multiple sclerosis-associated fatigue
The result of the study presented by Dr. MC Pantzaris and colleagues showed the efficacy of a formulations containing omga-3, omega-6 and vitamin A and -E in relapsing-remitting multiple sclerosis (RR-MS). We want to discuss here on potential benefits of almond as a natural source of these nutritional elements, and other previously shown beneficial nutritional elements in patients with MS and fatigue. Multiple Sclerosis (MS) is one of the most frequent causes of permanent disability in young adults. Its incidence and prevalence vary geographically, ranging from 0-60 per 100,000 in low frequency areas such as India or Brazil to 240-300 per 100,000 in high frequency areas like Canada and Sweden . MS is a heterogeneous disorder with different pathologic features including Inflammation, demyelination, and axonal degeneration [2,3]. The cause of MS is unknown, however it is widely accepted that MS is an inflammatory autoimmune disorder resulting in chronic neurodegeneration . Fatigue is a one of the most prevalent co-morbid conditions in patients with MS, with reported prevalence up to 90 percent . It has important disrupting effect on patient's daily activities and quality of life. The patients fatigue typically exacerbate as the day goes on. It is also a known association between fatigue and sleep disturbance in MS patients . It is suggested that axonal dysfunction and following increased recruitment of cortical areas and pathways in response to brain injury can be considered as pathologic mechanism of fatigue in patients with MS . A number of medications such as amantadine, methylphenidate, selective serotonin reuptake inhibitors, aspirin and modafinil are used in treating fatigue related to MS . Traditionally nutritional supplements are widely recommended and used in multiple sclerosis patients with fatigue [8,9]. Among different nutritional recommendations different preparations of Almond are very popular [10,11]. It is an excellent source of unsaturated fats (9 g per oz) and magnesium (76 mg per oz) which have shown their benefits in both conditions in different investigations.
Studies have shown an association between low levels of unsaturated fat consumption and an increased risk of MS . In vitro and animal studies also have demonstrated inhibiting the autoimmune pathways with the supplementation with poly unsaturated fatty acids (PUFA) . Some clinical trials also have confirmed beneficial potentials of PUFA supplementation in patients with MS .
Unsaturated fatty acids also have shown their benefits in clinical studies of fatigue patients with different causes . The bypass of impaired ability of the body to biosynthesize n-3 and n-6 long-chain polyunsaturated fatty acids by inhibiting the ?-6 desaturation of the precursor essential fatty acids is considered as the PUFA mechanism of action in patients with fatigue .
Magnesium, as another active ingredient of almond, has previously shown to be decreased in nervous tissue of patients with multiple sclerosis . Some clinical reports also have supported the role of magnesium supplementation in patients with multiple sclerosis . The important known role of magnesium in development, structure and stability of myelin is considered as possible mechanism of the mentioned effects. Magnesium has also shown its positive effects in patients with fatigue in multiple clinical studies . Supplementation of magnesium appears to improve subjective and objective measures of insomnia in elderly people and may become a useful instrument in managing sleep disorders as one of the etiological factors in development of fatigue [20,21]. According to the mentioned information almond along with its traditional use in patient with MS like symptoms , as a rich source of unsaturated fat and magnesium, can be considered hypothetically as a potential nutritional supplement in patients with MS. Upcoming clinical studies are required to evaluate its efficacy.

Is self-identification as 'obese' really a public health solution?
Johnson et al.  provide a benchmark figure for the low (and lowering) levels of identification with the term 'obese' in Great Britain. The stance of the article, not unreasonably, is that low self- identification is a problem for public health. An alternative conclusion might be that respondents have increasingly sophisticated appreciation of social desirability and demonstrate a valuable resistance to the negative stereotypes and stigma of obesity. Is there clear evidence that self- identification as 'obese' is actually good for you? The 'benefits' identified are more about responding to healthcare diagnosis and healthcare advice. Accepting advice from a health professional, albeit dressed up in medical categories, is different from self-identifying as obese in a social survey. In the meantime the evidence is mounting that amplifying the stigma of obesity puts people at risk of chronic stress with negative implications for weight management and long term health [2- 3]. So, it is a serious and pressing question: is beating your self up, identity-wise, about obesity really a public health solution? It seems to have been a gently downward path for society to collectively gain weight. The obvious response for public health is to retrace the steps rather than point out a stigmatised self-identification route for individuals to take up a cliff face. (Metaphorically of course!) Finding the political leadership to tackle the interests vested in an obesogenic path may be the real problem for public health.

Re:"Stroke incidence and association with risk factors in women: a 32-year follow- up of The Prospective Population Study on Women in Gothenburg.
Answer to Comment by prof Alain Braillon
Thank you for commenting on our paper "Stroke incidence and association with risk factors in women: a 32-year follow- up of the Prospective Population Study of Women in Gothenburg". We appreciate your proposals for extension of the paper, and in this reply, we have clarified the study design and added the inquired information.
1. We used continuous variables in the analysis of baseline data except for categorical data as the ordinal data for leisure time physical inactivity, self-perceived mental stress, education where a dichotomization was used in accord with given references and data in Methods and Supporting file with references. Smoking was assessed in three categories as described. Blood pressure, blood lipids were assessed and analyzed as continuous variables. The measures were repeated as described in the original papers with references given in the "supporting file". In addition to the baseline blood pressure values analyzed as continuous variables we also used baseline diagnosis of hypertension yes/ no according to present criteria at that time. The criteria are given in Methods. To add facts in the ongoing clinical discussion about low grade hypertension we studied three levels of hypertension 1-3 at baseline in accordance to modern guidelines. We further made a model-predicted risk plot for systolic and diastolic blood pressures. Risk factors as atrial fibrillation, myocardial infarction and diabetes during follow-up were analyzed through survival curves based on Cox regression analysis. We do not agree that the title is misleading; Studying associations between baseline risk factor levels in cohort studies (e.g. Framingham, Nurse's Health Study) is an accepted epidemiological method. However, as we have the advantage of access to 4 follow-up examinations in the Prospective Population Study of Women in Gothenburg (PPSWG) during the 32 year observation period (performed 1974,1980, 1992 and 2000), we could regard it as a limitation that we have not taken full advantage of the possibility to take into account also individual changes in risk factor levels during the 32 years. However, this was not within in the aim of this study which focused on associations between baseline risk factors and stroke during follow-up.
2. You are quite right that hazard ratio is a relative measure and gives no information about how soon stroke will occur. We have calculated median time to stroke for the women with systolic blood pressure <140 and >= 140, respectively, during the 32 years (n=105 and n=81), which was 27 (95% CI 24.17 - 26.44) and 24 (95% CI 20.50- 24.14) years (significant difference); and with diastolic blood pressure <90 and >= 90 (n=111 and n=75), which was 26 (95% CI 23.84-26.12) and 24 (95% CI 20.65-24.47) years(non-significant difference). '
3. We have calculated population attributable fraction (PAF) for hypertension as follows:
PAF% =100 x (NO-NE)/NT where NE= numbers expected in the exposed group if the (age standardized) risk is the same as in the control group; NO= numbers observed in the exposed group; NT= total number of cases. PAF% for SBP >140=10.91% PAF% for DBP >90=15.89%

Low-fats and not low-carbs for better diabetes control in Indians
This large study has clearly shown that Indians continue to consume more carbohydrates, but there was no association between this major source of calories and glucose levels in diabetics or non-diabetics. Since 1972, all national surveys in India have reported that there were no significant differences in dietary calories or carbohydrates, between normal populations and people with diabetes (newly ascertained or known).
I have conducted population surveys between 1986-1990, among migrants of Indian origin (Southall, London), first-generation Malaysian Indians (Kelang), and second-generation Indo-Guyanese (Enterprise), as well as in rural Indian populations from 5 Indian States - Himachal Pradesh (Kalpa), Delhi (Palam), Gujarat (Khubadthal and Kuha), Orissa (Erasama), Kerala (Arivikkara Konam and Kottayam). Among these migrant and rural Indian populations, there were no differences in the total energy intake and, proportions of total or complex carbohydrates and free sugars. Complex carbohydrates constituted major source of carbohydrates even in those with abnormal glucose tolerance. It was not possible to identify any specific Indian dietary pattern to relate with diabetes. But, there was some evidence to suggest that total fats are more in Indian diets (1). Based on these findings, we have successfully conducted long-term (3-year) intervention studies with reduced-fat diets, and demonstrated better diabetes control in type-2 diabetes (2) and prevention of diabetes development among people with prediabetes (3).
Current dietary advices for diabetes in India (and possibly in other Asian countries), are mostly based on Western literature and do not really apply to Indian context. It is not how much of 'sugar' one eats, but what matters is the amount and nature of the 'fat' in food. This warrants an urgent reconsideration of the conventional prescriptions of diabetic diets - "no rice, no sugar in coffee, no fruits or no potatoes" - just doesn't mean anything. Such practices inadvertently increase fat proportions in diets, and unknowingly diabetics are harmed. "No oils, no fats, no food fads" - should be the advice for diabetics in our country.

Primal Lakeshore Diet
Mosconi et al's (2014) fascinating study found a diet that is rich in produce and fish appears to be neuroprotective (1). This brought to mind some other literature.
It has been asserted that our brains were shaped for a tropical lakeshore lifestyle (2, 3). The land/water interface would have provided docosahexaenoic acid (DHA), which is needed for brain development. Early man is believed to have had a DHA-rich diet featuring fish, shellfish, and shorebird nestlings and eggs. This supported the shaping of the human brain.
It might also be argued that the tropical lakeshores likely would have been rich in plant life and thus produce. Milton (2000) points to physiological evidence indicating that our ancient ancestors ate a diet rich in tropical plant foods (4). There is some indication that phytochemicals play roles in brain health (5, 6). Produce would have also provided prebiotics (7). Gut microbiota are believed to influence brain health (8). A tropical lakeshore diet rich in prebiotics would have promoted a healthy gut ecosystem.
Thus Mosconi et al's (2014) study is consistent with the idea that our brains were shaped by a tropical lakeshore lifestyle and modern health educators should take our primal diet into consideration when developing nutritional advice.

Response to 'Supervised Learning Events: is rebranding enough?'
We read with interest Mr Ali's response (Supervised Learning Events: is rebranding enough?) to our article (1) and we agree with the sentiments expressed in his letter.
In terms of the issue of training raised by Mr Ali, although we did have a question on our discussion guide that asked trainees and trainers about their 'needs for SLE development in order to improve educational practice', we did not always specifically ask each participant 'what training have you had for SLEs?'. However, some participants did talk about this in response to our fourth research question (what are participants' suggestions for how SLEs should be developed?).
While some trainers talked about receiving information from their Deaneries but perhaps not fully engaging with it, others talked about finding out about SLEs through courses attended, sometimes about WPBAs/SLEs or the tools used within them, but also through their attendance at courses meant to be about something else. Therefore, SLE training for trainers, who discussed this issue, seemed to be variable, serendipitous and lacking coordination.
While some trainees mentioned receiving informal training about WPBAs/SLEs, formal training about SLEs was not particularly mentioned by our sample. Therefore, many of our study participants had not received training on SLEs.
One of the key recommendations from our study is that we need to improve trainee and trainers' understandings of SLEs (1). Ultimately, we agree with Mr Ali that we cannot begin to improve trainee and trainer perceptions about SLEs and educational practices around them without trainees and trainers having a better understanding of what they are and how best to do them.

Risk factors for stroke
Blomstrand et al's study on stroke incidence among women and associations with risk factors deserves comments.
First, using arbitrary cut-points for risk factors is not appropriate when there is a continuous distribution of the values with no obvious modal values. Moreover, they risk factors were based on a single assessment at baseline and there are multiple dimensions including amount and duration as well as timing. Accordingly, the title is misleading, although the incidence study is prospective, the risk factors study is cross sectional. Breaches in such basic principles contrasts with the use of Cox proportional hazards regression models with complex adjustments and may explain why hazard ratios were low. The box "Strengths and limitations of this study" must be modified.
Second hazard ratio is a relative measure, it tells us nothing about absolute risk and no gives us no information about how soon the stroke will occur.
Third, Blomstrand et al should provide the population attributable fraction (PAF) which facilitates the true understanding of the contribution of a risk factor to disease burden: PAF is the proportional reduction in population disease or mortality that would occur if exposure to a risk factor were reduced to an alternative ideal exposure scenario.

Fundamental concepts for male circumcision
Surgery should not be performed unless a medical condition has developed. This is a fundamental concept in surgery [1, 2]. Unless a disease or medical condition is present the risk of surgery cannot be balanced against a risk of disease. If no disease is present no risk can be accepted . This would make male circumcision in infants unacceptable, especially given the risk of death due to blood loss [3,4].
Hidden motivations for circumcision can result from the trauma associated with the amputation of an area of the genitals . People who have been circumcised, had people close to them circumcised or performed circumcision could encourage others to embrace circumcision, without fully considering the dangers, in order to deal with the trauma. This may occur consciously or subconsciously.
Research into amputation would require consenting adults who would be fully informed about what will be amputated and the associated dangers. An alternative to this would be people having tissue removed to help solve a medical problem that has developed. The person's health after the procedure can then be monitored and studied. For many occurrences of male circumcision it appears the surgery has been carried out on children and now attempts are being made to explain why it was done. An example of this is the argument about circumcision to prevent sexually transmitted diseases (STDs) and the human immunodeficiency virus (HIV). A person who is circumcised can still contract HIV.
Circumcision cannot be compared to vaccination as unlike vaccination it deprives the child of healthy tissue.
Care must be taken to watch out for any bias in research (conscious or subconscious). This is relatively easy to notice in male circumcision research. For example the basic surgical concept (mentioned above) will often not be addressed or mentioned. Alternative arguments will not be addressed or discussed. There are three examples of this for male circumcision. Firstly, alternative factors, such as personal hygiene and exposure to carcinogens will not be discussed or considered. Secondly, lack of education amongst adults and medics means they often retract the foreskin with force causing damage to the gland, foreskin and opening the urethra further increasing the risk of infection especially during bathing. This concept of lack of education is often ignored and forgotten when a bias exists. Thirdly, less extreme methods (such as education and testing before sexual intercourse for HIV prevention and less invasive surgery for foreskin tightness ) will be ignored.
