Aesthetic and cosmetic medical practices have attracted considerable consumer attention globally. However, possible complications vary and range from mild, self-resolving ecchymoses or edema to more persistent complications. The aim of this review is to identify the nutritional deficits or excesses associated with the major complications of reconstructive surgery, aesthetic surgery, and mini-invasive aesthetic procedures. An additional goal is to provide a bundle of actions for professionals working in the industry in order to reduce the risks of aesthetic procedures and improve the clinical outcomes. Granulomas, hypertrophic scars and keloids, seromas, infections and xerosis, hyperpigmentation, petechiae, livedo reticularis, slower wound healing, and other poor outcomes are frequently associated with nutritional deficiencies. Nutritional status can markedly affect wound healing and tissue repair following surgical interventions, as well as the outcomes of aesthetic and cosmetic medical practices. Professionals working in this industry, therefore, need to consider the nutritional aspects of their patients to obtain the best results.

This review was prepared jointly by the World Bank Group and the World Food Programme (WFP), building on the comparative advantages of both organizations. It examines the evidence base for school feeding programs with the objective of better understanding how to develop and implement effective school feeding programs in two contexts: a productive safety net, as part of the response to the social shocks of the global food, fuel and financial crises, and a fiscally sustainable investment in human capital, as part of long-term global efforts to achieve Education for All and provide social protection to the poor.

In 1973, San Francisco allergist Ben Feingold created an uproar by claiming that synthetic food additives triggered hyperactivity, then the most commonly diagnosed childhood disorder in the United States. He contended that the epidemic should not be treated with drugs such as Ritalin but, instead, with a food additive-free diet. Parents and the media considered his treatment, the Feingold diet, a compelling alternative. Physicians, however, were skeptical and designed dozens of trials to challenge the idea. The resulting medical opinion was that the diet did not work and it was rejected. Matthew Smith asserts that those scientific conclusions were, in fact, flawed. An Alternative History of Hyperactivity explores the origins of the Feingold diet, revealing why it became so popular, and the ways in which physicians, parents, and the public made decisions about whether it was a valid treatment for hyperactivity. Arguing that the fate of Feingold's therapy depended more on cultural, economic, and political factors than on the scientific protocols designed to test it, Smith suggests the lessons learned can help resolve medical controversies more effectively.

Background: Extrauterine growth retardation is a major clinical problem in very-low-birth-weight infants. Parenteral nutrition (PN) serves to achieve rapid maximal nutrition in early postnatal life. There is a lack of uniformity with regard to neonatal PN practice. The objective of this study is to ascertain current practice regarding neonatal PN prescription in the early postnatal period in the United Kingdom. Methods: A study questionnaire was e-mailed to neonatal pharmacists serving level 3 and major level 2 units in the United Kingdom between October 2005 and March 2006. Static numerical information regarding glucose, amino acids, and lipid prescription during the first 10 days of life was collected and compared with current recommendations. Results: Fifty-two (81%) units responded to the questionnaire; 4 units were excluded for incomplete data. Twenty-six units (54%) initiated PN on day 1. Full PN was achieved by the median age of 6 days. Twelve units (25%) achieved full PN only by day 7 or later. Maximum median amino acids were 2.9 g/kg/d. Only 13 units (27%) prescribed ≥3 g/kg/d, and 2 prescribed more than 3.5 g/kg/d. Nineteen units (39%) initiated lipids on day 1. Eleven units (23%) delayed lipids until day 3, and 2 units delayed lipids until day 4. In comparison to the recommended intake of calories and amino acids, the current median prescription would result in a cumulative deficit over the first 10 days of 420 kcal/kg and 11.9 g/kg, respectively. Conclusions: Our study suggests diverse practice with regard to neonatal PN prescription in the United Kingdom. Current neonatal PN practice entails a significant calorie and protein deficit during early postnatal life and warrants further review. Extrauterine growth retardation is an important clinical problem in preterm infants. We present data on parenteral nutrition prescriptions from major neonatal units in the U.K. The current prescription entails a significant calorie and protein deficit, and warrants an urgent review.

Compensatory growth is an organism's reaction to buffer deviations from targeted trajectories. We explored the compensatory patterns of juvenile brown trout under field and laboratory conditions. Divergence of size and condition trajectories was induced by manipulating food levels in the laboratory and then releasing the trout into a river. In the stream, the length trajectories of food-restricted and control fish were parallel, but food-restricted fish exhibited partial compensation for mass and rapid recovery of condition. A laboratory experiment on similar sized fish did not provide evidence for compensatory growth in length or mass. In contrast, data matched the compensatory patterns shown in the stream: length trajectories were parallel and the convergence of mass trajectories ceased as soon as food-restricted fish recovered condition to the level of controls. These results show that (i) brown trout did not compensate for depression in structural growth and (ii) mass recovery was targeted to reinstate condition or energy reserves, but not size at a given age. This does not support the common view that compensatory growth can be a general response to growth depression. Rather, compensation in other salmonids could be related to size thresholds associated with developmental switches at the onset of sexual maturation and migration.

Wernicke–Korsakoff syndrome (WKS) is induced by thiamine deficiency (TD) and mainly related to alcohol consumption. Frontal cortex dysfunction has been associated with impulsivity and disinhibition in WKS patients. The pathophysiology involves oxidative stress, excitotoxicity and inflammatory responses leading to neuronal death, but the relative contributions of each factor (alcohol and TD, either isolated or in interaction) to these phenomena are still poorly understood. A rat model was used by forced consumption of 20% (w/v) alcohol for 9 months (CA), TD hit (TD diet + pyrithiamine 0.25 mg/kg, i.p. daily injections the last 12 days of experimentation (TDD)), and both combined treatments (CA+TDD). Motor and cognitive performance and cortical damage were examined. CA caused hyperlocomotion as a possible sensitization of ethanol-induced excitatory effects and recognition memory deficits. In addition, CA+TDD animals showed a disinhibited-like behavior which appeared to be dependent on TDD. Additionally, combined treatment led to more pronounced alterations in nitrosative stress, lipid peroxidation, apoptosis and cell damage markers. Correlations between injury signals and disinhibition suggest that CA+TDD disrupts behaviors dependent on the frontal cortex. Our study sheds light on the potential disease-specific mechanisms, reinforcing the need for neuroprotective therapeutic approaches along with preventive treatments for the nutritional deficiency in WKS.

A healthy diet during pregnancy has been recognized for centuries as key for the well-being of the mother and the fetus. Over time, the definition of an ideal diet has progressively switched from a diet at a low-risk of nutritional deficiencies to a diet that reduced the risk of diseases that relates to overeating. The rediscovery of the Mediterranean diet and vegetarian diets has gained a growing interest, mainly because they may protect from the most commonly encountered chronic diseases linked to “overeating” in the developed and developing world, including the array of cardiovascular diseases, diabetes, and obesity. The evidence on advantages and drawbacks of plant-based diets in pregnancy is scant, and heterogeneous also on the account of the link with higher education and health awareness in Western countries, and with poverty in the developing world. However, well-balanced plant-based diets are theoretically welcomed in both settings: they are rarely “too rich” and may protect from overnutrition in high resourced countries, and they are often more affordable in low-resourced countries. The present review contextualizes vegetarian/vegan diets in four situations: the “healthy and wealthy,” who choose them in the Western words, the “poor and obliged” in low-resourced settings, the “nutritionally disturbed,” on the account of the link between nutritional disturbances and plant-based diets in the Western world, and the “sick and controlled,” i.e., the specific experience on protein-restricted diets in patients with chronic kidney diseases. Overall, well-balanced, varied, and controlled, plant-based diets in pregnancy are nutritionally safe, and they are not associated with clinical problems in either mother nor child, in health and disease, provided they are varied and balanced enough and attention is paid to cover the nutritional requirements (in particular, vitamin B12, vitamin D, iron, and zinc).

Current knowledge about the relationship between mild to moderately inadequate maternal iodine intake and/or supplemental iodine on child neurodevelopment is sparse. Using information from 77,164 mother-child pairs in the Norwegian Mother and Child Cohort Study, this study explored associations between maternal iodine intake and child attention-deficit/hyperactivity disorder (ADHD) diagnosis, registered in the Norwegian Patient Registry and maternally-reported child ADHD symptoms at eight years of age. Pregnant women reported food and supplement intakes by questionnaire in gestational week 22. In total, 1725 children (2.2%) were diagnosed with ADHD. In non-users of supplemental iodine (53,360 mothers), we found no association between iodine intake from food and risk of child ADHD diagnosis (p = 0.89), while low iodine from food (<200 µg/day) was associated with higher child ADHD symptom scores (adjusted difference in score up to 0.08 standard deviation (SD), p < 0.001, n = 19,086). In the total sample, we found no evidence of beneficial effects of maternal use of iodine-containing supplements (n = 23,804) on child ADHD diagnosis or symptom score. Initiation of iodine supplement use in gestational weeks 0–12 was associated with an increased risk of child ADHD (both measures). In conclusion, insufficient maternal iodine intake was associated with increased child ADHD symptom scores at eight years of age, but not with ADHD diagnosis. No reduction of risk was associated with maternal iodine supplement use.

Attention deficit hyperactivity disorder (ADHD) has been linked to excessive weight; however, the underlying mechanisms of this association are not well understood. To date, the bidirectional associations between ADHD and nutritional status in childhood have been explored in a limited number of studies, with particularly few of those incorporating body composition data. This study aims to evaluate the associations of ADHD symptoms, nutritional status, and body composition in childhood. We analyzed data from 3940 children from the 2015 Pelotas (Brazil) Birth Cohort at 4 and 6-7 years of age. Linear regression was performed to evaluate the association between ADHD symptoms and nutritional status (weight, height, and body mass index [BMI]) at ages 4 and 6-7, as well as body composition, specifically fat mass (FF) and fat-free mass (FFM) at ages 6-7. Moreover, a cross-lagged panel model (CLPM) analysis between ADHD symptoms and BMI was performed to explore the bidirectional associations. ADHD symptoms were associated with increased height (β 0.01, 95%CI 0.001, 0.026) and FFM (β 0.02, 95%CI 0.008-0.035) at age 4, and increased BMI (β0.02, 95%IC 0.002, 0.038), weight (β 0. 02, 95%CI 0.005, 0.039), height (β 0.01, 95%CI 0.000, 0.024), and FFM (β 0.02, 95%CI 0.012, 0.040) at ages 6-7. Although the CLPM indicated a small effect suggesting a bidirectional relationship between ADHD symptoms and BMI, the observed associations were not statistically significant: ADHD scores at age 4 predicting BMI z-scores at ages 6-7 (β 0.003; 95% CI: -0.026, 0.020), and BMI z-scores at age 4 predicting ADHD scores at ages 6-7 (β 0.013; 95% CI: -0.018, 0.044). Children with higher ADHD symptoms showed increased growth in weight, height, and BMI. The observed increase in weight and BMI was attributed to greater FFM in these children.

Over 10% of US children and adolescents have attention-deficit hyperactivity disorder (ADHD), with a similar prevalence among youth athletes. While ADHD may confer certain athletic performance advantages such as heightened quickness, decision-making and periods of hyperfocus, it also poses some challenges including reduced concentration, frustration, and possible increased injury risk. Pharmacologic treatments, including stimulant-based medications, can improve attentiveness and athletic performance but could alter nutritional behaviors such as appetite suppression. This paper reviews the current literature on nutritional strategies to provide practical sports nutrition guidelines for children and adolescent athletes with ADHD. Evidence suggests that optimizing energy intake, emphasizing complex carbohydrates, improving fat quality intake, and consuming adequate amounts of micronutrients may support both athletic performance and ADHD symptom management. In contrast, excessive added sugars and saturated fats are associated with poorer outcomes and manifestation of ADHD symptoms. Although no research examining nutritional interventions in youth athletes with ADHD have been performed, applying established sports nutrition principles for youth athletes with ADHD offers a promising approach to enhance performance, reduce injury risk, and support the long-term health of the athlete.
