Obesity in Prediabetic Patients: Management of Metabolic Complications and Strategies for Prevention of Overt Diabetes.

Obesity and prediabetes affect a substantial part of the general population, but are largely underdiagnosed, underestimated, and undertreated. Prediabetes differs from diabetes only in the degree of hyperglycaemia consequent to the progressive decline in residual beta-cell function. Both prediabetes and diabetes occur as a consequence of insulin resistance that starts several years before the clinical onset of overt diabetes. Macrovascular complications in patients with diabetes are mainly caused by insulin resistance. This is why in prediabetes, the overall cardiovascular risk is, by all means, similar to that in patients with diabetes. It is important, therefore, to identify prediabetes and treat patients not only to prevent or delay the onset of diabetes, but to reduce the cardiovascular risk associated with prediabetes. This review provides an overview of the pathophysiology of prediabetes in patients with obesity and the progression toward overt diabetes. We have reviewed nutritional and pharmacological approaches to the management of obesity and reduced glucose tolerance, and the treatment of the major comorbidities in these patients, including hypertension, dyslipidaemia, and Metabolic dysfunction-associated Steatotic Liver Disease (MASLD), has also been reviewed. In patients with obesity and prediabetes, the nutritional approach is similar to that adopted for patients with obesity and diabetes; treatments of dyslipidaemia and hypertension also have the same targets compared to patients with diabetes. MASLD is a critical issue in these patients; in the prediabetic state, MASLD rarely progresses into fibrosis. This highlights the importance of the early recognition of this pathological condition before patients become diabetic when the risk of fibrosis is much higher. It is necessary to raise awareness of the clinical relevance of this pathological condition in order to prompt early intervention before complications occur. The single most important therapeutic goal is weight loss, which must be early and persistent.

The neurohypophyseal hormone oxytocin and eating behaviors: a narrative review.

BACKGROUND: The neuropeptide oxytocin (OT) is crucial in several conditions, such as lactation, parturition, mother-infant interaction, and psychosocial function. Moreover, OT may be involved in the regulation of eating behaviors. METHODS: This review briefly summarizes data concerning the role of OT in eating behaviors. Appropriate keywords and medical subject headings were identified and searched for in PubMed/MEDLINE. References of original articles and reviews were screened, examined, and selected. RESULTS: Hypothalamic OT-secreting neurons project to different cerebral areas controlling eating behaviors, such as the amygdala, area postrema, nucleus of the solitary tract, and dorsal motor nucleus of the vagus nerve. Intracerebral/ventricular OT administration decreases food intake and body weight in wild and genetically obese rats. OT may alter food intake and the quality of meals, especially carbohydrates and sweets, in humans. DISCUSSION: OT may play a role in the pathophysiology of eating disorders with potential therapeutic perspectives. In obese patients and those with certain eating disorders, such as bulimia nervosa or binge/compulsive eating, OT may reduce appetite and caloric consumption. Conversely, OT administered to patients with anorexia nervosa may paradoxically stimulate appetite, possibly by lowering anxiety which usually complicates the management of these patients. Nevertheless, OT administration (e.g., intranasal route) is not always associated with clinical benefit, probably because intranasally administered OT fails to achieve therapeutic intracerebral levels of the hormone. CONCLUSION: OT administration could play a therapeutic role in managing eating disorders and disordered eating. However, specific studies are needed to clarify this issue with regard to dose-finding and route and administration time.

Eating Disorders in the Time of the COVID-19 Pandemic: A Perspective.

BACKGROUND: Due to the COVID-19 pandemic, current epidemiological conditions may exacerbate the risk of new-onset, recurrence and relapse of eating disorders. This perspective aims to better analyse the phenomenon. RESULTS: Some data suggest that new-onset and recurrence/relapse of eating disorders are increasing due to the pandemic. Government restrictions, self-confinement, social isolation, restriction to healthcare facilities access, delayed access to diagnosis and cure, fear of contagion, distress and difficulties related to the telemedicine approach contribute to this burden. The Immune system dysfunction usually observed in undernourishment (e.g., anorexia nervosa) could delay the diagnosis of respiratory infections, including COVID-19, and predispose to possible bacterial superinfections. Conversely, patients with binge eating, obesity or metabolic syndrome are susceptible to high-grade systemic inflammation and poor prognosis once the infection has occurred. DISCUSSION: More detailed data combining research on eating disorders and COVID-19 are required despite some evidence. Many data show that telemedicine has beneficial aspects, but its impact on long-term mental health is still poorly understood. Short- and long-term consequences of COVID-19 in patients with eating disorders are unknown, but they will likely become more apparent over time. CONCLUSION: Working on emotion regulating strategies in a post-pandemic world, when people have inadequate control over the background of negative emotions, could be a future treatment strategy. Long-term studies with a larger sample size are essential to assess the long-term consequences of the blockade on patients and their healthcare providers and identify useful strategies to improve clinical management.

Nutraceuticals and Oral Supplements in Cancer Prevention: A Narrative Review.

BACKGROUND: Epidemiological studies have shown that food is a compelling means of maintaining a state of well-being and preventing diseases. Many malignant diseases are related to nutrition, and the nutrient-organism interaction could define the balance between health and disease. Nutrients and dietary components influence epigenetic phenomena and modify drug response so that food-organism interactions may influence individual predisposition to disease and its potential therapeutic response. AIMS: In this review, we highlighted emerging opinions and data on a large cluster of nutraceuticals, as well as functional foods and specific dietary patterns, with respect to cancer, including breast, pancreas, prostate, and colorectal. Only those nutraceuticals and nutritional supplements yielding sufficient and convincing data have been reported in this review; molecules with inconclusive clinical evidence will not be discussed. CONCLUSION: Growing and accumulating evidence is validating the use of nutraceuticals in cancer settings. However, a knowledge gap remains in terms of causal evidence for several compounds where a window for further clinical studies is left.

Eating Disorders and Type 1 Diabetes: A Perspective.

Patients with type 1 diabetes (T1D) are at risk of clinical eating disorders (EDs) and disordered eating behaviors (DEBs) than the general population. This burden is related mainly to diabetes-related physical and psychosocial issues especially beginning during childhood. DEBs must be investigated carefully and promptly managed in case of suspicion, as they can evolve into severe clinical EDs over time and are strictly related to poor outcomes. The significant number of scientific articles dealing with the relationship between T1D and DEBs or EDs confirms the complexity of these problems and the difficulties in diagnosis and treatment. This paper examined current scientific literature related to this topic, emphasizing the epidemiological and clinical complexity of the phenomenon and briefly summarizing EDBs management strategy in T1D patients.

Assessment of Burnout Levels Before and During COVID-19 Pandemic: A Web-Based Survey by the (Italian) Association of Medical Endocrinologists (AME).

BACKGROUND: Some endocrinologists were involved in the management of patients with suspected or confirmed COVID-19 during the first wave of the pandemic. This study aims to analyze burnout levels among the Association of Medical Endocrinologists (AME) members before and during the pandemic. METHODS: We recruited two AME members samples at two different times: before COVID-19 (n = 811) and during the first wave of the ongoing pandemic (n = 579). Both the samples filled the Maslach Burnout Inventory. We performed MANOVAs to evaluate demographic and COVID-19 related differences in burnout levels and Pearson's Chi-square test to compare burnout severity before and during the pandemic. RESULTS: Women reported higher Emotional Exhaustion and reduced Professional Accomplishment than men. The oldest physicians had lower levels of Emotional Exhaustion and Depersonalization and higher Professional Accomplishment than younger workers. Independent contractors displayed lower levels of burnout compared to established contractors. Finally, the pandemic, per se, did not lead to changes in burnout levels. DISCUSSION: Women and young physicians are at higher risk of burnout. It is also possible that front- line professionals are at higher risk during a health care crisis. Moreover, it is likely that the length of exposure to the pandemic has not been sufficient to impact burnout levels. CONCLUSION: Short-term exposure to pandemic-related activities seemed to have a low impact on burnout severity, except for physicians directly involved in managing COVID-19 cases. It is strongly recommended the availability of psychological support in public hospitals.

Eating disorders during COVID-19 pandemic: the experience of Italian healthcare providers.

PURPOSE: Due to COVID-19 pandemic, the Italian population lived in quarantine from March to May 2020 (lockdown phase I). Restrictions impacted individuals' psychological health, especially in those with eating disorders (ED). Healthcare providers (HCPs) treating ED provided assistance by telemedicine and/or in walk-in clinics. We hypothesize that social restrictions represented a great stressor for ED patients and HCPs, negatively impacted their therapeutic alliance, and affected the frequency of dysfunctional behaviors. METHODS: This cross-sectional study consisted of an online survey investigating the experience of HCPs involved in ED treatment, with a specific focus on difficulties concerning the therapeutic efficacy. Questionnaire (n. 18 questions) was formulated ad hoc by our research team and sent by e-mail to Italian HCPs registered on online platforms. HCPs included ED experts specialized in psychology, nutrition or medicine. Data were collected during lockdown phase I and referred to patients with Anorexia Nervosa-(AN), Bulimia Nervosa (BN)-and Binge-Eating Disorder-(BED). RESULTS: One-hundred questionnaires were collected; 84 and 76 were included in our qualitative and quantitative analyses, respectively. Thirty-six% of HCPs felt their therapeutic intervention was unsuccessful, 37% complained compromised therapeutic alliance. Changes in frequency of compensatory behaviors (increased in 41% AN and 49,5% BN; reduced in 14,6% AN and 21,8% BN) and binge-eating episodes (increased in 53,3% BN and 30,5% BED; reduced in 30,7% BN and 24,7% BED) were experienced and ascribed to augmented patient's anxiety. Disorders switches and variation in dysfunctional conducts frequency were both significantly related to ED category (p < 0.05 for all). Concentration techniques were recognized as useful to offset such negative outcomes. CONCLUSION: According to HCPs, social restrictions affected the frequency of dysfunctional behaviors in ED patients and the efficacy of their therapeutic intervention. Further long-term studies are needed to confirm our data in a larger sample size. LEVEL IV: Novel results from a cross-sectional study.

Anorexia Nervosa and Comorbid Psychopathology.

BACKGROUND AND OBJECTIVE: There is great interest, supported by clinical experience, in the relationship between Eating Disorders (EDs) and psychiatric symptoms and diseases. The psychopathology of EDs is also referred to many risk and protective factors, and there is some evidence in the literature, also about genetic and neurobiological factors involved. The aim of this review is to examine and synthesize the recent scientific literature on this topic, in particular the complex relationship between Anorexia Nervosa and Neuropsychiatric Disorders. METHODS: We analyzed the best of published literature on the topic, identifying keywords and MeSH terms in Pubmed and then searching them. The last search was performed on November 2017. RESULTS: Psychiatric comorbidities are very common in anorexia nervosa. Mood disorders, major depressive disorders, anxiety disorders, obsessive-compulsive disorders, developmental disorders among autistic spectrum and attention-deficit hyperactivity disorder and even some personality disorders, substance abuse and borderline traits have been reported, and some observations suggest a positive genetic correlation between anorexia nervosa and schizophrenia. CONCLUSION: The great amount of scientific articles dealing with the relationship between EDs and psychopathology confirms the complexity of these problems and the difficulties in diagnosis and treatment. An accurate diagnosis and assessment of clinical risk about psychological, psychiatric, nutritional and somatic aspects are therefore essential for an appropriate therapeutic management of patients affected by anorexia nervosa.
