Abstract
This review critically assessed the existence of presbygeusia, i.e., the impairment in taste perception occurring in the elderly, as a natural part of the aging process and its potential clinical implications. Several factors might contribute to age-related taste alterations (TAs), including structural changes in taste buds, alterations in saliva composition, central nervous system changes, and oral microbiota dysbiosis. A comprehensive literature review was conducted to disentangle the effects of age from those of the several age-related diseases or conditions promoting TAs. Most of the included studies reported TAs in healthy elderly people, suggesting that presbygeusia is a relatively frequent condition associated with age-related changes in the absence of pathological conditions. However, the impact of TAs on dietary preferences and food choices among the elderly seems to be less relevant when compared to other factors, such as cultural, psychological, and social influences. In conclusion, presbygeusia exists even in the absence of comorbidities or drug side effects, but its impact on dietary choices in the elderly is likely modest.

The Role of Nutritional Support for Cancer Patients in Palliative Care.
Cotogni, P, Stragliotto, S, Ossola, M, Collo, A, Riso, S, On Behalf Of The Intersociety Italian Working Group For Nutritional Support In Cancer,
Nutrients. 2021;(2)
Abstract
The role of nutritional support for cancer patients in palliative care is still a controversial topic, in part because there is no consensus on the definition of a palliative care patient because of ambiguity in the common medical use of the adjective palliative. Nonetheless, guidelines recommend assessing nutritional deficiencies in all such patients because, regardless of whether they are still on anticancer treatments or not, malnutrition leads to low performance status, impaired quality of life (QoL), unplanned hospitalizations, and reduced survival. Because nutritional interventions tailored to individual needs may be beneficial, guidelines recommend that if oral food intake remains inadequate despite counseling and oral nutritional supplements, home enteral nutrition or, if this is not sufficient or feasible, home parenteral nutrition (supplemental or total) should be considered in suitable patients. The purpose of this narrative review is to identify in these cancer patients the area of overlapping between the two therapeutic approaches consisting of nutritional support and palliative care in light of the variables that determine its identification (guidelines, evidence, ethics, and law). However, nutritional support for cancer patients in palliative care may be more likely to contribute to improving their QoL when part of a comprehensive early palliative care approach.

Abstract
The world is currently facing the coronavirus disease (COVID-19) pandemic which places great pressure on health care systems and workers, often presents with severe clinical features, and sometimes requires admission into intensive care units. Derangements in nutritional status, both for obesity and malnutrition, are relevant for the clinical outcome in acute illness. Systemic inflammation, immune system impairment, sarcopenia, and preexisting associated conditions, such as respiratory, cardiovascular, and metabolic diseases related to obesity, could act as crucial factors linking nutritional status and the course and outcome of COVID-19. Nevertheless, vitamins and trace elements play an essential role in modulating immune response and inflammatory status. Overall, evaluation of the patient's nutritional status is not negligible for its implications on susceptibility, course, severity, and responsiveness to therapies, in order to perform a tailored nutritional intervention as an integral part of the treatment of patients with COVID-19. The aim of this study was to review the current data on the relevance of nutritional status, including trace elements and vitamin status, in influencing the course and outcome of the disease 3 mo after the World Health Organization's declaration of COVID-19 as a pandemic.

Abstract
AIMS: The incidence of type 1 diabetes has increased over the last decades. The pathological pathway is not yet clear, even if genetic and environmental risk factors are known. An early diagnosis can avoid ketoacidosis and its complications. This work aims to discuss the determinants of both ketoacidosis at the onset and access by hospital emergency departments without a suspected diagnosis. METHODS An observational bi-centric prospective study was conducted in Northern Italy, on a paediatric population including Italian and migrant patients at the diabetes onset. Seventy-four type 1 diabetes patients, both Italian and migrant, were included in the study. Anthropometric, socio-economic, behavioural, clinical data were collected, and microbiota analyses were performed using stool samples. RESULTS Regular physical activity is associated with lower ketoacidosis incidence at onset (OR 0.33 95% CI 0.12-0.95 p < 0.05), as is higher blood vitamin D level (OR 0.92 95% CI 0.85-0.99 p < 0.05). Moreover, a higher weaning age (OR 0.49 95% CI 0.27-0.89 p < 0.05), higher vitamin D level (OR 0.90 95% CI 0.83-0.98 p < 0.05) and a higher level of Akkermansia muciniphila (OR 0.46 95% CI 0.25-0.87 p < 0.05) are associated factors to lower frequency of type 1 diabetes onset without a suspected diagnosis. Diabetes migrant status is not a risk factor for severe type 1 diabetes onset; on the other hand, some protective factors are significantly more diffused among Italians, such as regular sport activity and non-critical vitamin D levels. CONCLUSION Behavioural and nutritional data, such as microbiota bio-indicators, seem to be useful to identify an at-risk population to prevent ketoacidosis and its severe complications.

Abstract
AIM: Natriuretic peptides are not only involved in cardiovascular adaption to various conditions, but also in metabolic diseases. We performed this study to assess the effect of a very short time of lifestyle inpatient intervention on NTproBNP values in normotensive subjects with severe obesity and normal cardiac function. METHODS We recruited 14 consecutive obese normotensive subjects with normal cardiac function who were aged 30 years and more and were referred to inpatient rehabilitation in an academic clinic over a two months period. They were examined at baseline and after a 3-weeks program including dietary intervention with hypocaloric diet and assisted personalized physical aerobic and anaerobic activities and compared to age, sex and BMI-matched control subjects under usual care. RESULTS BMI significantly decreased (40.8 ±1.6 vs 42.3 ± 1.6 kg/m2, p <0.0001). Median reduction in body weight was 4.9 kg (interquartile range 2.4-5.2 kg). After diet and exercise-induced weight loss, plasma NTproBNP levels showed an almost two-fold increase, which was statistically significant (28.2 ± 12.3 vs 17.2 ± 13.2 ng/L, p = 0.01), and particularly relevant in the subgroup with NT-proBNP values below median values compared to those with higher values (p = 0.02). No significant variations were found in control subjects (18.0 ± 13.0 vs 16.5 ± 11.2 ng/L, p = 0.18). The lipid profile was significantly ameliorated, and both HbA1c and insulin levels showed a marginally non-significant decrease after treatment. CONCLUSIONS An almost two-fold increase in NTproBNP levels was evident after a very short time period of lifestyle intervention in normotensive severe obese patients without cardiac disease. This finding might have clinical relevance, considering the role of NT-proBNP as risk factor of impaired glucose tolerance.

Abstract
Gender medicine focuses on the patho-physiological, clinical, prevention and treatment differences in diseases that are equally represented in men and women. The purpose of gender medicine is to ensure that each individual man and woman receives the best treatment possible based on scientific evidence. The concept of "gender" includes not only the sexual characteristics of individuals but also physiological and psychological attributes of men and women, including risk factors, protective/aggravating effects of sexual hormones and variances linked to genetics and corporal structures that explain biological and physiological differences between men and women. It is very important to consider all the biological, physiological, functional, psychological, social and cultural characteristics to provide patients with individualized disease management. Herein, we critically analyze the literature regarding gender differences for diseases and acquired conditions of the most representative hepatic pathologies: primary biliary cirrhosis, autoimmune hepatitis, primary sclerosing cholangitis, non alcoholic fatty liver disease and alcoholic liver disease, and viral chronic hepatitis B and C. The last section addresses hemochromatosis, which is a prevalent iron overload disorder in the Caucasian population. This review aims to describe data from the literature concerning viral chronic hepatitis during pregnancy, management during pregnancy and delivery, and new effective drugs for the prevention of maternal infection transmission without significant adverse effects or complications.
