Abstract
Diet-induced thermogenesis, influenced primarily by protein intake, generates energy from food. Herein, we present the case of anorexia nervosa in a 30-year-old woman, who developed intermittent fever while transitioning from continuous to intermittent tube feeding, with an increase in protein intake. Extensive investigations ruled out infection- or drug-related causes, indicating that intermittent fever resulted from diet-induced thermogenesis due to high protein administration. Recognizing the potential for diet-induced thermogenesis in cases of fever during tube feeding is crucial to avoid unnecessary antibiotic use and prevent the discontinuation of essential medications.

Abstract
Introduction We examined if acute ingestion of a novel thermogenic supplement influences resting energy expenditure (REE), mood, and hemodynamic function. Methods Forty-six adults completed this randomized, placebo-controlled, double-blind, crossover study. Participants underwent two conditions: placebo (PL) and treatment (TX) containing 300 mg of caffeine and 3 g of acetyl-L-carnitine. REE, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and mood states were assessed at baseline and 30, 60, and 120 minutes post-ingestion. Data were analyzed using repeated measures analysis of variance. Results A significant condition-by-time interaction was observed for REE. At the 30-, 60-, and 120-minute post-ingestion timepoints, REE was 202 ± 26, 238 ± 40, and 209 ± 29 kcal/d greater in the TX condition compared to PL. No significant differences were observed for SBP and HR but a significant interaction indicated that DBP was elevated at 30 minutes in the TX vs. PL, though values remained within normal ranges. Significant interactions were observed for perceived alertness, concentration, energy, and focus, with increases in TX. Conclusion These data provide evidence that acute consumption of the thermogenic dietary supplement OxyShred (EHPlabs, Salt Lake City, Utah, USA) stimulates increases in REE that are sustained for ≥ two hours, along with increasing perceived alertness, concentration, energy, and focus. Changes in hemodynamic function are minimal and within normal ranges.

Abstract
This narrative review delves into the complex and intricate mechanisms of the gut-brain axis. Gut microbiota has gained immense importance in the treatment of various diseases. The therapeutic potential of gut-microbial modulation is slowly coming to light. With good preclinical evidence, some human studies shed light on the translation potential of gut-microbial modulation. The concept of gut-microbial modulation has been studied for over a few decades. The relationship between gut microbiota and various homeostatic mechanisms is fascinating. Over the years, we have started understanding the immense role of gut microbiota in various homeostatic mechanisms. There are a good number of clinical studies that have shown the therapeutic potential of gut-microbial modulation in obesity and psychological diseases, especially depression and anxiety. The gut-microbial modulation can be achieved by dietary factors or supplementation. In this review, we explore the mechanisms by which prebiotics, probiotics, and synbiotics alter the gut-brain axis. The review limits its discussion to the most recent clinical studies that have shown promise as therapeutic strategies.

Abstract
INTRODUCTION The potential influence of micronutrient status on obesity should be considered. Nevertheless, previous research examining the relationship between serum vitamin B12 levels and obesity has yielded inconclusive results. The objective of this study was to investigate the associations between serum vitamin B12 levels and obesity and diabetes mellitus (DM) in a population consisting of persons aged 18 years and older. METHODS A retrospective case-control research was undertaken on a sample of 1024 individuals aged 18 years and older who were admitted to a tertiary healthcare facility (Recep Tayyip Erdoğan University Education and Research Hospital, Rize) for either overweight-related issues or routine check-ups. The primary objective of this study was to assess the B12 levels of these individuals. The researcher recorded the body mass index (BMI) and history of DM for all subjects. RESULTS The study comprised a total of 1024 participants, consisting of 834 females and 190 males. The levels of vitamin B12 in women were found to be 308±113 pg/mL, while in men, the levels were 304±125 pg/mL. The results of the statistical analysis indicate that there is no statistically significant disparity in vitamin B12 levels between males and females (p=0.748). There was a statistically significant positive correlation seen between age and B12 levels; however, the magnitude of this connection was found to be minor (p=0.000, R2=0.017). The study findings revealed that out of the 1,024 individuals evaluated, 179 individuals exhibited B12 levels below 200, while 845 individuals displayed vitamin B12 levels above 200. The study findings indicated that there was no statistically significant distinction observed in the occurrence of obesity and DM in relation to vitamin B12 deficiency (p = 0.938, p = 0.08, respectively). CONCLUSION The results of this study offer empirical support for the notion that there is no significant difference in vitamin B12 levels between individuals afflicted with obesity and diabetes and those unaffected by these conditions. Interestingly, it was shown that serum B12 levels exhibited a modest increase with advancing age.

Abstract
Background Body mass index (BMI) is an important indicator of overweight and obesity. Unlike BMI, body fat percentage (BF%) can be utilized to estimate body composition regardless of weight and height. The association between BMI and BF%, as well as the impact of age and gender, may help estimate the prevalence of obesity more clearly. This study aimed to assess the relationship between BMI and BF%, examine the effect of age and gender on this relationship, and establish the linearity/curvilinearity of this relationship. Methodology The body composition analysis of 1,150 participants in various institutional events (institution foundation day) during 2019 and 2023 was performed using the Accuniq bio-electrical impedance analyzer (BIA) (Accuniq, Netherlands). The participants included undergraduate, postgraduate medical, and PhD students, as well as employees of All India Institute of Medical Sciences, New Delhi. Age groups were categorized as under 17 years, young adults (18-25 years), adults (26-44 years), middle-aged adults (45-59 years), and older adults (≥60 years). Pearson's correlation coefficient (r) was used for analyzing the relationship between BMI and BF%. To assess the effect of age and gender on this relationship, multiple regression analysis was applied, and polynomial regression was applied to test its linearity. The data were analyzed using SPSS version 25 (IBM Corp., Armonk, NY, USA). Results Males made up a larger proportion of the participants (56.3%; 647). The mean age of the participants was 36.5 ± 13.6 years. The mean BMI and BF% were 24.7 ± 4.0 kg/m2 and 29.1 ± 8.7%, respectively. A significant and moderate positive correlation (r = 0.630, p < 0.01) was observed between BMI and BF%. The mean ± SD of BMI and BF% had a directly proportional relationship with age. Among both genders, females showed a greater correlation (r = 0.852). Both age and gender had a significant effect on this relationship, with gender impacting more than age (β = 0.488, p < 0.000). The curvilinear nature of the relationship between BMI and BF% was demonstrated with the female model showing a more precise fit (R2 = 0.72, standard error of the estimate = 3.3%). Conclusions The relationship between BMI and BF% was significant and positive in this group of Indians. This relationship was significantly impacted by age and gender and was curvilinear in nature. Females had a higher association than males between BMI and BF%. The study suggests that BMI, BF%, and the effects of age and gender should be taken into consideration when predicting obesity.

Abstract
INTRODUCTION This study evaluated the nutrition literacy and perceived emotional burden of disease in young adults with type-1 diabetes. All participants are current or past members of the non-profit organization The Diabetes Link, formally known as the College Diabetes Network. The Diabetes Link is a 501(c)(3) nonprofit organization working to connect and support young adults with type-1 diabetes through the transitional periods of their lives, most commonly the transition from high school to college. Previous research shows that there is a significant uptick in glycated hemoglobin (HbA1c) levels in people with type-1 diabetes between the ages of 18 and 24, a period associated with many transitional events. While there are numerous hypothesized reasons why HbA1c levels spike during these ages, the lack of nutritional knowledge is frequently highlighted as a root cause of this increase. METHODS Participants were asked to complete a 40-question survey via Google Forms (Google LLC, Mountain View, California, United States) that contained questions pertaining to their treatment, dietary habits, confidence in healthcare professionals to provide nutrition advice, and overall feelings toward their diagnosis of type-1 diabetes. The survey also included four questions aimed at evaluating the participants' carbohydrate-counting skills to determine a basis of their nutritional knowledge. A binary logistic regression was performed using IBM SPSS Statistics for Windows, Version 27 (Released 2020; IBM Corp., Armonk, New York, United States) to assess the influences of the burden and carbohydrate-counting knowledge on the participants' diabetes care, eating habits, and emotional outlook on nutrition. RESULTS Data from this study show that the participants who scored high on the carbohydrate-counting quiz were 2.389 times more likely to avoid eating because of an out-of-range blood sugar level (p-value = 0.05), and the participants who reported higher levels of burden were 9.325 times more likely to avoid social gatherings because of food (p-value = 0.002). Conclusion: Results from this study demonstrate that the emotional burden associated with eating and not nutrition knowledge could contribute to the previously listed spike in HbA1c levels.

Abstract
Background Peritoneal dialysis patients are malnourished due to loss of protein in the dialysate and inadequate dialysis, although they take additional calories every day during treatment. Many parameters are used to assess nutritional status, with normalized protein catabolic rate (nPCR) being one of the most common. Asprosin, a novel adipokine secreted by adipose tissue, peaks during fasting and induces hepatic glucose release through the activation of the G-protein-cAMP-PKA pathway, which has been indicated to have a curative effect on chronic inflammation. In this study, we aimed to investigate the relationship between asprosin levels and nutritional parameters in patients receiving peritoneal dialysis treatment as well as to investigate the applicability of more practical tests. Methodology A total of 70 peritoneal dialysis patients, 35 female (59%) and 24 male (41%), were included in the study. The mean age of the patients was 53 ± 14 years (range = 18-80 years), and the median peritoneal dialysis duration was 31.5 months (range = 20-56.2 months). The most common etiologic cause was hypertension (37%). Patients over 18 years of age who had been receiving peritoneal dialysis treatment for at least 24 months were included in the study. The correlation between patients' nPCR levels and serum asprosin, body mass index, and lipids was evaluated. Results The correlation between the level of nPCR and the serum asprosin level, body mass index, and lipids was evaluated. Patients with nPCR <0.815 were considered malnourished, and factors affecting malnutrition were determined by univariate analysis. Among the factors affecting malnutrition according to univariate analysis, those with p-value <0.05 were analyzed by multivariate analysis. Low asprosin level was one of the independent factors affecting malnutrition in patients (Exp(B) = 0.944, 95% confidence interval (CI) = 0.896-0.994). Other independent factors affecting malnutrition were Kt/V (Exp(B) = 0.018, 95% CI = 0.001-0.550) and residual renal function (Exp(B) = -0.004, 95% CI = 0.993-0.999). Conclusions There is a need for more accessible tests and reliable parameters to evaluate dialysis and nutritional deficiency in peritoneal dialysis patients. One possible hormone that could serve as a guide is asprosin.

Abstract
Hyperkalemic periodic paralysis (HyperKPP) is a rare disease with significant anaesthetic implications. We compare two perioperative courses in the same patient. The first surgery resulted in paralysis and a protracted hospitalisation, while the second surgery resulted in a same-day discharge. Various anaesthetic techniques may be used; however, clear communication surrounding optimisation both for home medications (eg, continuing potassium wasting diuretics) and avoidance of triggering medications (primarily: depolarising neuromuscular blockers), along with thermoregulation and glucose management plans, is critical and best performed early by an anaesthetic precare clinic. Our cases highlight the physiological underpinnings in managing patients with HyperKPP.

Abstract
Obesity is considered an independent risk factor for increased hospital length of stay and can be an obstacle to a safe discharge. Although typically prescribed in the outpatient setting, initiating glucagon-like peptide-one receptor agonists (GLP-1RAs) in the inpatient setting can be efficacious in reducing weight and increasing functional status. We report the use of GLP-1RA therapy with liraglutide and subsequent transition to subcutaneous semaglutide weekly in a 37-year-old female with severe obesity, weighing 694 lbs (314 kg) with a body mass index (BMI) of 108 kg/m2. Multiple medical and socioeconomic factors impaired the patient from being safely discharged and ultimately led to prolonged hospitalization. The patient received 31 consecutive weeks of GLP-1RA therapy in the inpatient setting along with a very low-calorie diet (800 kcal/day). Initiation and up-titration doses were completed using liraglutide for a total of five weeks. Subsequently, the patient was transitioned to receive weekly semaglutide and completed 26 weeks of therapy. At the end of week 31, the patient's weight decreased by 174 lbs (79 kg), or 25% of baseline weight, and BMI decreased from 108 to 81 kg/m2. GLP-1RAs offer a promising avenue for weight loss interventions in patients with severe obesity in addition to lifestyle modifications. The weight loss observed in our patient at the halfway point of the total treatment duration is a milestone in the pathway to gaining functional independence and meeting the criteria for future bariatric surgery. Semaglutide, a GLP-1RA, can be an effective intervention for severely obese patients with BMI greater than 100 kg/m2.

Abstract
BACKGROUND Obesity is a major public health concern in the United States, especially since it has been associated with an increased incidence of multiple co-morbidities. Positive eating behavior modifications learned through nutrition education sessions are the main interventions proposed to target overweight and obesity. OBJECTIVE The aim of this study was to determine if nutrition education and hands-on cooking classes will result in improvement in eating habits and cooking skills to manage chronic disease. Methods: A convenience sample of 21 participants were recruited from primary health clinics in Miami-Dade, Broward, and Palm Beach counties. A total of eight weekly virtual lessons were conducted, which included both a culinary and a nutrition education portion. At baseline and post-intervention, participants filled out a validated questionnaire with questions related to nutrition knowledge and behavior, fruit and vegetable consumption, and cooking skills. Weight was self-reported. Statistical analysis was conducted using IBM SPSS Statistics for Windows, Version 27.0 (Released 2020; IBM Corp., Armonk, New York, United States) and included descriptive statistics and a paired t-test to compare pre- and post-intervention data. RESULTS Throughout the eight weeks, subject attendance ranged from 61-95%. Nineteen participants completed the post-intervention questionnaire. Results showed a statistically significant mean weight loss of 3.74 ±5.26 lbs (p=0.006) and a statistically significant mean BMI change of -0.66 ±0.86 (p=0.004) at post-intervention compared to baseline. In addition, subjects reported increased confidence in dietary habits and culinary skills post-intervention. CONCLUSION Our results show exciting data in support of this project's objectives that a healthy cooking intervention can increase nutrition knowledge, increase confidence in healthy food choices, increase confidence in food preparation skills, and improve weight and BMI in participants.

Abstract
We present the case of a young male patient who presented with paralysing muscle weakness due to severe hypokalaemia and hypophosphataemia. The initial patient history evaluations could not establish the aetiology. Only after we reviewed the patient's history did he reveal that he had been following a severe calorie-restricted regime, the human chorionic gonadotropin diet, which had ended 2 days prior to developing symptoms. This information then allowed us to diagnose severe refeeding syndrome. As a further complication, the patient developed rhabdomyolysis. After correction of serum electrolytes, symptoms resolved completely. This case emphasises the potential harm of severely calorie-restricted diets, often recommended by online 'experts'. Furthermore, we underline the importance of thorough history taking.

Abstract
Metabolic syndrome (MS) is a collection of pathological metabolic conditions that includes insulin resistance, central or abdominal obesity, dyslipidemia, and hypertension. It affects large populations worldwide, and its prevalence is rising exponentially. There is no specific mechanism that leads to the development of MS. Proposed hypotheses range from visceral adiposity being a key factor to an increase in very-low-density lipoprotein and fatty acid synthesis as the primary cause of MS. Numerous pharmaceutical therapies are widely available in the market for the treatment of the individual components of MS. The relationship between MS and vitamin B complex supplementation, specifically folic acid and vitamin B12, has been a subject of investigation worldwide, with several trials reporting a positive impact with vitamin supplementation on MS. In this study, an all-language literature search was conducted on Medline, Cochrane, Embase, and Google Scholar till September 2021. The following search strings and Medical Subject Headings (MeSH) terms were used: “Vitamin B12,” “Folate,” “Metabolic Syndrome,” and “Insulin Resistance.” We explored the literature on MS for its epidemiology, pathophysiology, newer treatment options, with a special focus on the effectiveness of supplementation with vitamins B9 and B12. According to the literature, vitamin B12 and folate supplementation, along with a host of novel therapies, has a considerable positive impact on MS. These findings must be kept in mind while designing newer treatment protocols in the future.

Abstract
Hunger and inadequate nutrition are ongoing concerns in rural Malawi and are exemplified in traditional proverbs. Traditional proverbs and common expressions offer insight into commonly held truths across societies throughout sub-Saharan Africa. Strong oral traditions allow community beliefs embodied in proverbs to be passed down from generation to generation. In our qualitative study, we conducted 8 individual and 12 focus group interviews with a total of 83 participants across two districts in rural central Malawi with the aim of soliciting context-specific details on men and women's knowledge, attitudes and practices related to nutrition, gender equality and women's empowerment. Each interview began by asking participants to share common proverbs related to nutrition. Our qualitative analysis, informed by an indigenous-based theoretical framework that recognises and centres African indigenous knowledge production, yielded six themes: 'a black dog enters the home', 'don't stay with your hands hanging', 'a man is at the stomach', 'showers have fallen', 'we lack peace in our hearts' and 'the hunger season'. Traditional proverbs can provide insight into the underlying causes of hunger and malnutrition. Physicians, nurses and other allied health professionals around the world have a role to play in addressing hunger and malnutrition, which have been exacerbated by climate change. We have an ethical duty to educate ourselves and others, and change our behaviours, to mitigate the root causes of climate change, which are contributing to food insecurity and resultant poor health outcomes in countries like Malawi.

Abstract
Sjogren's syndrome (SS) is an autoimmune disease with involvement of multiple organs, including both glandular and extraglandular organs. Usually involvement of glandular organs manifests before the extraglandular ones, but when the sequence is reversed, diagnosis may be missed. Hypokalaemic quadriparesis in SS is not uncommon. Respiratory failure in hypokalaemia is not usually seen, but in SS, it has been reported. We report a case of a 55-year-old woman who presented with sudden onset flaccid quadriparesis and respiratory muscle paralysis secondary to severe hypokalaemia. On detailed investigation, she was detected to have distal renal tubular acidosis secondary to clinically inapparent and asymptomatic SS.

Abstract
We present a case of extreme bradycardia in an 18-year-old man, accompanied by bilateral pleural effusions, pericardial effusion, endocrine dysregulation and Horner's syndrome. Despite extensive investigations as an inpatient and multidisciplinary input, it was not until subsequent assessment by an endocrine team that it was revealed that his presentation was attributable to an eating disorder. Following dietary advice, easing of extreme exercise and continued support, the patient improved in all parameters including body mass index and he remains well. This case demonstrates the importance of a thorough personal history incorporating all aspects of social and dietary history.

Abstract
The link between folate deficiency and congenital spina bifida defects was first suggested in the 1960s. Although the prevention of these defects by preconception folic acid supplementation was confirmed in a large multi-centre controlled trial in 1991, its subsequent implementation as health education advice has made very little difference. North America’s policy of folic acid fortification of flour and bread has had a beneficial impact. No European country has implemented fortification due to concern over possible adverse effects on older subjects, but a recent review shows these to be largely hypothetical and far outweighed by beneficial effects. Recent research by Menezo et al. has, however, shown that folic acid is ineffective for some women with severe fertility problems including recurrent miscarriage and failed in vitro fertilisation. There is a genetically determined bottleneck (677TT) in their folate metabolism that can be successfully overridden by going straight to the next step in the metabolic pathway and taking 5-methylytetrahydrofolate, as a preconception supplement. Menezo suggests that all women with fertility problems should be tested for 677TT. If fortification of flour and bread is to be implemented in the UK, there should be monitoring for possible adverse effects including the incidence of colorectal cancers and cognitive decline. In conclusion, whilst there are concerns that fortification could have a detrimental effect on these conditions, there is sound evidence that it would have much greater beneficial effects.

Abstract
We report a case of right paraduodenal hernia with strangulation of almost the entire small bowel at presentation. Since resection of all bowel of doubtful viability would have resulted in too little residual length to sustain life, a Bogota bag was fashioned using transparent plastic material from an urine drainage bag and the patient monitored intensively for 18 hours. At re-laparotomy, clear demarcation lines had formed with adequate length of viable bowel (100 cm) and resection with anastomosis was done with a good outcome on follow-up, 9 months after surgery. Our description of a rare cause of strangulated intestinal obstruction and a novel method of maximising length of viable bowel is reported for its successful outcome in a low-resource setting.

Abstract
Severe anaemia in patients who cannot receive blood transfusion is an indication for the use of hyperbaric oxygen therapy (HBO). Most reports of the use of HBO for anaemia involve patients with acute blood loss. This report details a case of HBO used for a patient with severe pernicious anaemia. A 35-year-old Jehovah's Witnesses believer presented to a hospital with fatigue, dyspnoea and haemoglobin of 26 g/L. She was diagnosed with pernicious anaemia. As she could not receive blood transfusion due to her religious beliefs, vitamin B12 supplementation and HBO were administered and resulted in significant improvement in her condition. The mechanisms of action of HBO, including increased systemic plasma oxygenation, can alleviate signs and symptoms of anaemia regardless of its aetiology. HBO administration can greatly enhance the plasma arterial oxygen content, leading to clinical improvement in patients with anaemia who cannot receive blood transfusion.

Abstract
A 63-year-old woman presented with ulcerations of both lower legs. Symptom onset was 2006. In 2013 she saw a dermatologist and a biopsy suggested livedoid vasculopathy. In 2016 a whole food plant-based diet (WFPB) was advised as a potential treatment in the community setting. The patient changed her diet accordingly, but was not otherwise treated. The symptoms remitted completely with close adherence to the WFPB diet and recurred on multiple occasions associated with poor dietary adherence. There was a self-identified dose-response relationship with degree of adherence and number and intensity of flares. There were no known adverse side effects from the diet change, although the patient felt adherence to be difficult at times. The mechanism is not completely clear; we speculate that the dietary changes directly affect vascular endothelial health, which in turn affects propensity towards a prothrombotic state. More research is needed to elucidate potential mechanisms.

Abstract
Ulnar stress fractures have been reported in athletes performing repetitive, high-impact activities, such as baseball pitchers and gymnasts. Crutch-assisted walking also results in cyclical forearm loading. We report the first case of ulnar stress reaction due to axillary crutch use. A 23-year-old right-handed woman experienced right forearm pain and imaging confirmed a right ulnar stress injury. The patient was also found to have mild hypercortisolism, low bone mass and vitamin D deficiency. Crutches were discontinued and physical therapy to normalise weight bearing through the left leg was prescribed. The patient's right forearm symptoms resolved and she was started on oral vitamin D supplementation. Axillary crutch use may result in ulnar stress injury, particularly in vulnerable populations. The addition of an upper extremity injury to someone with impaired mobility may compound disability. As such, clinicians should be aware of the clinical presentation of ulnar stress fractures in the long-term axillary crutch user.

Abstract
Orthorexia is a putative new eating disorder vying for a place in the DSM, roughly meaning "eating right". While a continuum can be drawn between anorexia and orthorexia, there are enough differences to make this disorder a distinct one. In this paper, I trace the origins of the term and its clinical career to date, employing Ian Hacking's concept of "ecological niche" to establish the place of orthorexia as a contemporary cyberpathy, a digitally transmitted disorder inwardly and narrowly focused on health through the consumption of "pure" foods. I critique both the notions of "health" and "purity" in this context, showing that orthorexia can only be understood in the context of healthism, an individual preoccupation with health in the context of neoliberalism. Using Jordan Younger's Breaking Vegan memoir (2015) and "Balanced Blonde" blog as a case study, I argue that orthorexia replicates via a digital proliferation of entrepreneurship of the self. Ultimately, this excessive preoccupation with health as a neoliberal cultural pathology bares life of meaning.

Abstract
Background Cerebral folate deficiency (CFD) syndrome is characterised by a low concentration of 5-methyltetrahydrofolate in cerebrospinal fluid, while folate levels in plasma and red blood cells are in the low normal range. Mutations in several folate pathway genes, including FOLR1 (folate receptor alpha, FRα), DHFR (dihydrofolate reductase) and PCFT (proton coupled folate transporter) have been previously identified in patients with CFD. Methods In an effort to identify causal mutations for CFD, we performed whole exome sequencing analysis on eight CFD trios and identified eight de novo mutations in seven trios. Results Notably, we found a de novo stop gain mutation in the capicua (CIC) gene. Using 48 sporadic CFD samples as a validation cohort, we identified three additional rare variants in CIC that are putatively deleterious mutations. Functional analysis indicates that CIC binds to an octameric sequence in the promoter regions of folate transport genes: FOLR1, PCFT and reduced folate carrier (Slc19A1; RFC1). The CIC nonsense variant (p.R353X) downregulated FOLR1 expression in HeLa cells as well as in the induced pluripotent stem cell (iPSCs) derived from the original CFD proband. Folate binding assay demonstrated that the p.R353X variant decreased cellular binding of folic acid in cells. Conclusion This study indicates that CIC loss of function variants can contribute to the genetic aetiology of CFD through regulating FOLR1 expression. Our study described the first mutations in a non-folate pathway gene that can contribute to the aetiology of CFD.

Abstract
Introduction Obesity is associated with increased morbidity and mortality and is an independent risk factor for the development and progression of chronic kidney disease (CKD). This study investigated the effect of a community-based, lifestyle-focused, weight-loss intervention on renal function among participants at baseline following 12 weeks of therapy. Methods A retrospective analysis of adults enrolled in a weight management program from 2009 to 2014 was conducted. Participants consumed at least 800 kilocalories per day in meal replacements, attended weekly behavioral education classes, and expended approximately 300 kilocalories per day in physical activity. The primary outcome was the association of weight loss and changes in glomerular filtration rate (GFR). Secondary outcomes included changes in blood sugar levels, lipid parameters, blood pressure, and the use of medication for hypertension and diabetes mellitus. Results Of the 71 participants, 63.4% were female, the average weight was 289 pounds, the average body mass index (BMI) of 53, and baseline GFR 47 ml/min/1.73m2. Following 12 weeks of the intervention, 76.1% of participants improved in CKD stage, 22.4% remained within the same stage, and 1.5% progressed to a higher stage (3A to 3B). Analysis revealed a correlation between weight loss and improved GFR (p=0.0006). Improvements were noted in blood sugar levels, blood pressure, and lipids (p<0.05). Medications were reduced in 61.8% of participants for hypertension and 83.3% for diabetes. Conclusions A significant correlation was observed between weight loss and improved renal function, with most participants improving in CKD stage. Participants also improved in markers of chronic disease and required fewer medications. When controlling for both diabetes and hypertension, the effect of improved renal function persisted.

Abstract
Ghrelin is a peptide hormone that is primarily released from the stomach. It is best known for its role in appetite initiation. However, evidence also suggests that ghrelin may play a much wider role in energy homeostasis and glucose metabolism. It is known that exogenous ghrelin exerts an orexigenic signal via growth hormone secretagogue receptors in the arcuate nucleus of the hypothalamus. However, blocking ghrelin signalling in the arcuate nucleus does not decrease feeding. Evidence now proposes that an alternative pathway for ghrelin’s action is via the vagus nerve. Furthermore, it has been suggested that ghrelin signalling is an important physiological regulator of body adiposity and energy storage. Ghrelin also seems to be important in controlling glucose metabolism through action in the pancreatic islets of Langerhans, representing a promising novel therapeutic target in diabetes treatment. Despite these findings, further research in humans is required before ghrelin can be indicated as a therapeutic target in obesity or diabetes. This review summarises the current literature concerning ghrelin’s physiological roles in energy and glucose homeostasis.

Abstract
A 66-year-old Caucasian woman was admitted with deteriorating mental health in the setting of background history of schizophrenia and depression. Her husband reported that she had increasing negative thoughts and decreased motivation regarding her self-care over a few weeks with no obvious stressors. Initial laboratory tests were unremarkable except for isolated normocytic anaemia. Physical examination revealed widespread bilateral upper limb ecchymoses and lower limb petechial rash. After an extensive investigation with no definitive results to explain her clinical presentations, diagnosis of scurvy was suspected and confirmed with severely low serum vitamin C level. Her clinical symptoms improved markedly with oral supplementation, which further supported the diagnosis of scurvy. Although it is now a rare condition in developed countries, this case will remind modern medical practitioners that patients with scurvy may present with non-specific symptoms and clinical findings such as depression and anaemia.

Abstract
A 69-year-old man with type 2 diabetes, hypertension and stage 3 chronic kidney disease (CKD), hyperphosphataemia and borderline hyperkalaemia presented to an office visit interested in changing his diet to improve his medical conditions. He adopted a strict whole-foods, plant-based diet, without calorie or portion restriction or mandated exercise, and rapidly reduced his insulin requirements by >50%, and subsequently saw improvements in weight, blood pressure and cholesterol. His estimated glomerular filtration rate (eGFR) increased from 45 to 74 mL/min after 4.5 months on the diet and his microalbumin/creatinine ratio decreased from 414.3 to 26.8 mg/g. His phosphorus level returned to the normal range. For individuals with CKD, especially those with obesity, hypertension, or diabetes, a strict, ad libitum whole-food, plant-based diet may confer significant benefit, although one must consider potential limitations of a creatinine-based GFR equation in the face of significant weight loss.

Abstract
A 61-year-old obese man presented with 8-week history of nausea and occasional vomiting. He reported poor appetite and unintentional weight loss of more than 20 kg of his body mass. A week after admission, he developed double vision and unsteady gait. Neurological examination revealed isolated sixth cranial nerve palsy on the left side with horizontal nystagmus that progressed to bilateral lateral gaze palsy with normal vertical gaze. Brain MR revealed T2/fluid attenuation inversion recovery (FLAIR) high signal in mammillary bodies, tectum of the midbrain and the periaqueductal grey matter. He was diagnosed with Wernicke's encephalopathy (WE). WE is a medical emergency that carries high mortality yet can be often under-diagnosed in the non-alcoholic patient. Varied presentation and absence of alcohol dependence lowers the degree of suspicion and this was true in this case. The patient was given intravenous thiamine and made a rapid and dramatic recovery.

Abstract
While scurvy is considered to be a rare disease in the modern era, the disease still presents in certain populations with nutritional deficiencies such as those with poor nutritional absorption secondary to gastrointestinal disorders and in patients with poor nutritional intake. We present a case of scurvy in a patient who had eosinophilic oesophagitis which limited his oral intake. He presented with the classic symptoms of scurvy including a perifollicular rash, arthralgia, gingivitis and anaemia. He was treated with intravenous vitamin C initially followed by an oral course after which he showed improvement. This case demonstrates that it is important to consider vitamin C deficiency in patients with who present with anaemia and bleeding stigmata specifically in those who have poor nutritional intake. Furthermore, additional consideration should be given to patients with malnutrition as part of the preoperative evaluation.

Abstract
A 28-year-old man with fever, atraumatic lower limb pain and rash was noted to have multiple areas of ecchymosis involving both lower limbs. He was anaemic and also had a grossly swollen left leg. Differential diagnoses of compartment syndrome, vascular tear, platelet and clotting factor disorders, vasculitis and myositis were ruled out. Scurvy was only considered after failing to reach a diagnosis. A dietary history revealed consumption of a restricted diet with no fresh fruits or vegetables. Diagnosis was supported by an undetectable vitamin C level in blood and a rapid improvement of symptoms on oral vitamin C replacement. Prevalence of vitamin C deficiency in developed countries is also discussed.

Abstract
Thiamine is an important coenzyme, which is essential for metabolism and maintaining cellular osmotic gradient. Thiamine deficiency can cause focal lactic acidosis, alteration of the blood-brain barrier and the production of free radicals through cell death by necrosis and apoptosis. Wernicke encephalopathy (WE) is a clinical diagnosis. Cytotoxic and vasogenic oedema are the most typical neuroimaging findings of WE, presenting as bilateral symmetrical hyperintense signals on T2-weighted MR images. MRI is not necessary for the diagnosis of WE, but it can be helpful in ruling out alternative diagnosis. We present the case of an 61-year-old man with the history of class II obesity presenting with diplopia, dysarthria and vertigo, confirmed to be non-alcoholic WE. We aim to highlight the occurrence of WE in patients with large bowel resection though. Delay in diagnosis, particularly in obese individuals due to lack of suspicion, can lead to grim prognosis.

Abstract
This is a single case of a 65-year-old American woman who presented with substantial weight gain and insulin resistance (IR) post-Roux-en-Y gastric bypass (RYGB) surgery. Before RYGB, she had reached 340 lbs (155 kg) and a body mass index (BMI) of 56.6 kg/m2 The surgery resulted in a 70 lbs (32 kg) weight loss, bringing her BMI, per cent total weight loss (%TWL) and per cent excess weight loss (%EWL) to 44.9 kg/m2, 20.6% and 36.8%, respectively. Unfortunately, her BMI would return to 53.6 kg/m2, nearly her pre-RYGB BMI. It was then she sought the guidance of a primary care physician with expertise in nutrition and medical management of obesity, who placed her on a ketogenic diet. One year later, she had lost 102 lbs (46.4 kg), resulting in a BMI, %TWL and %EWL of 36.6 kg/m2, 31.7%, and 63.1%, respectively, also further resulting in significant improvements of her inflammatory biomarkers. This case presentation will explore current literature, covering the effects of obesity on IR, pre-diabetes and other disease-provoking inflammatory biomarkers.

Abstract
A 62-year-old male, previously well, was referred to neurology clinic following 6 months history of worsening lower limbs instability, paraesthesia, pain and weakness rendering him housebound. Examination revealed upper motor neuron pattern of weakness of the lower limbs and loss of proprioception. Serum analysis revealed reduced caeruloplasmin and copper levels with raised zinc. Spinal imaging revealed subtle dorsal column intensity changes in C2-C7, confirmed with 3T MRI. A copper deficiency myeloneuropathy was diagnosed secondary to chronic use of a zinc-containing dental fixative paste. The paste was discontinued and a copper supplementation was started. Resolution of symptoms was not achieved with intensive physiotherapy. The patient remains a wheelchair user though progression of symptoms has halted. Prompt recognition and treatment of hyperzincaemia-induced hypocupraemia earlier in the disease course may have prevented any irreversible neurological deficit.

Abstract
Objective To analyze the seasonal variations in calcidiol and parathyroid hormone serum levels along a natural year in a paediatric population living in a region of the north of Spain considering a normal nutrition status. Design A cross-sectional study. Setting Navarra Hospital Complex, Pamplona, Spain. Participants A total of 413 Caucasian individuals (aged 3.1 to 15.4 years): 227 school children (96 males and 131 females) and 186 adolescents (94 males and 92 females), with normal nutritional status. Main outcome measures Clinical examination (sex, age, weight, height and body mass index) and blood testing (calcium, phosphate, alkaline phosphatase, calcidiol and parathyroid hormone) during the year 2014. Results Calcidiol levels were lower during spring (25.96 ± 6.64 ng/mL) and reached its maximum level in summer (35.33 ± 7.51 ng/mL); parathyroid hormone levels were lower in summer (27.13 ± 7.89 pg/mL) and reached maximum level in autumn (34.73 ± 15.38 pg/mL). Hypovitaminosis D prevalence was 14.3% in summer and 75.3% in spring. Parathyroid hormone levels were compatible with secondary hyperparathyroidism in eight individuals (1.9%). There is a correlation (p < 0.01) between calcidiol and parathyroid hormone (r = −0.336). Logistic regression showed significant increased risk of hypovitaminosis in females (OR:1.63) and adolescents (OR:1.77), and when blood samples taken in autumn (OR:12.22), winter (OR:8.54) and spring (OR:19.72). Conclusions There is a high prevalence of hypovitaminosis D in the paediatric population with a healthy nutrition situation in Navarre, mainly during the months of autumn and winter, and, especially, in spring time. Given the difficulties in maintaining a sufficient amount of body vitamin D content along the year, it should be considered to give vitamin supplements and/or increase the intake of its natural dietary sources or vitamin D fortified foods.
