Background/Objectives: The COVID-19 pandemic severely impacted healthcare systems globally, with Italian healthcare professionals experiencing heightened stress, organizational challenges, and a significant psychological burden. This study investigates the frequency of depressive symptoms and health-related quality of life (H-QoL) among outpatient healthcare workers in Italy, comparing pre-pandemic (2017) and post-pandemic (2025) periods. Methods: A cross-sectional study was conducted in 2025, including 97 healthcare professionals from five outpatient departments at the University Hospital of Cagliari. Participants completed demographic surveys, the Short Form Health Survey (SF-12), and the Patient Health Questionnaire (PHQ-9) to assess H-QoL and depressive symptoms. Data were compared with previously published data from the same facility collected in 2017 and with pre-pandemic Italian community surveys. Results: Compared to 2017, there was a statistically significant increase in depressive episodes (38.1% vs. 33.2%, p = 0.01) and a higher proportion of individuals with low H-QoL (62.9% vs. 43.5%, p < 0.0001) in 2025. After age- and sex-standardization, both depressive symptoms and low H-QoL were significantly more prevalent among healthcare professionals in 2025 compared with the general population before the pandemic. Within the 2025 sample, non-medical healthcare workers showed a significantly higher prevalence of depressive symptoms than medical doctors, while female healthcare workers were more likely to report low H-QoL. Conclusions: Despite the pandemic's end, healthcare workers, especially those in outpatient settings, continue to face elevated psychological distress. Specific professional and gender-related vulnerabilities persist, and structural challenges, such as staff shortages and organizational issues, may exacerbate this burden. Sustained mental health support and targeted systemic interventions remain crucial to mitigate the long-term impact on the healthcare workforce.

AIMS:Obesity and sleep disorders are highly prevalent conditions with profound implications for public health. Emerging evidence highlights a bidirectional relationship between these two conditions, with each exacerbating the other in a complex interplay of behavioral, physiological, and hormonal mechanisms. Sleep deprivation and poor sleep quality contribute to energy imbalance through dysregulation of appetite hormones (e.g., leptin and ghrelin), increased caloric intake, and reduced physical activity. Conversely, sleep disorders such as obstructive sleep apnea syndrome (OSAS), insomnia, and restless leg syndrome (RLS) are significantly more common in individuals with obesity. DATA SYNTHESIS:This review explores the pathophysiological mechanisms underlying this relationship, including the roles of inflammation, autonomic dysregulation, and neuroendocrine pathways. Sleep loss exacerbates metabolic syndrome components, including insulin resistance and dyslipidemia, further perpetuating weight gain. Similarly, obesity-induced sleep disorders lead to pro-inflammatory states, vascular dysfunction, and sympathetic overactivation, compounding cardiometabolic risks. Specific conditions like OSA and RLS are examined as models of this interdependence, emphasizing their shared pathways and clinical implications. CONCLUSIONS:The bidirectional link between obesity and sleep disorders underscores the importance of integrating sleep assessment and management into obesity treatment strategies. Addressing this relationship could mitigate the progression of cardiometabolic comorbidities and improve overall health outcomes. Moreover, the intertwined dynamics between obesity, sleep disorders, and mental health-mediated by inflammatory pathways, hormonal dysregulation, and neurobehavioral factors-highlight the critical need for integrated treatment approaches targeting physical, psychological, and sleep-related dimensions to enhance health and quality of life.

The Mediterranean Diet (MD) has been associated with reduced inflammation and improved immune regulation, suggesting a potential protective role against autoimmune diseases. This review was conducted in accordance with PRISMA 2020 and MOOSE guidelines. A comprehensive search of PubMed/MEDLINE, Scopus, Embase, and Cochrane Library was performed up to February 28, 2024. Study quality was assessed using the Newcastle-Ottawa Scale, and the certainty of evidence was evaluated with the NUTRIGRADE approach. Pooled effect sizes were computed using a random-effects model and expressed as risk ratios (RR), hazard ratios (HR), or odds ratios (OR), as appropriate. A total of 9 high-quality studies were included. No significant associations were found between high vs. low MD adherence and the incidence of rheumatoid arthritis (RR = 0.99, 95% CI: 0.97-1.01), lupus (HR = 0.97, 95% CI: 0.91-1.03), Crohn's disease (RR = 0.95, 95% CI: 0.84-1.07), or ulcerative colitis (RR = 1.02, 95% CI: 0.97-1.08). A significant inverse association was observed for multiple sclerosis (RR = 0.91, 95% CI: 0.85-0.98) and for Sjögren's syndrome (OR = 0.81, 95% CI: 0.66-0.99). However, the certainty of evidence for all outcomes was rated as low. Promising associations were observed for multiple sclerosis and Sjögren's syndrome, although current evidence does not support a consistent protective effect of the MD across several other autoimmune diseases. Further longitudinal research is needed to confirm these findings and explore underlying mechanisms. Meanwhile, the promotion of MD adherence remains justified within broader public health strategies for chronic disease prevention.

Parathyroid hormone controls calcium and phosphate metabolism. The latter is also regulated by both FGF23 and 1–25(OH)2VitaminD. The polymorphic variant c.716 C > T of the FGF23 gene was previously found to be associated with renal phosphate leak/nephrolithiasis. The aim of our research is to study the metabolism of phosphate in a cohort of patients with primary hyperparathyroidism (PHPT) and its impact on bone and kidney. We have retrospectively compared a large sample of sporadic PHPT patients (339) with historical comparison cohort (HCC 503: Olivetti Study Group and Siena Osteoporosis Study). Moreover, in 51 PHPT patients, phosphate metabolism indexes were also revaluated at least 2 years after surgical cure. The variant c.716 C > T of the FGF23 gene was genotyped in patients and in a small sample of the control group. In PHPT patients we found higher levels of serum calcium, PTH, alkaline phosphatase, beta-C-terminal telopeptide (CTx), urinary calcium, while serum phosphate, 25OH-VitaminD, maximal tubular renal phosphate reabsorption adjusted for glomerular filtration rate (TmPO4/GFR) were lower than what was found in HCC. In PHPT patients fibroblast growth factor 23 (FGF23) levels were higher than in controls. Patients with kidney stones carried the 716 T allele more frequently than patients without it (χ2 7.20, p = 0.027). In PHPT patients revaluated at least 2 years after surgery, we observed a significant reduction of 1–25(OH)2VitaminD and FGF23. According to the median of serum phosphate levels, PHPT patients were subdivided into two subgroups: ≤2.8 mg/dL and > 2.8 mg/dL. The lowest phosphate group had a significantly higher serum calcium, PTH, 1–25(OH)2VitaminD, urinary calcium and a higher prevalence of kidney stones than in the highest phosphate group. The rate of males in the lowest phosphate group was significantly higher than in the highest phosphate group. Our study shows that the regulators of phosphate metabolism in PHPT patients are higher than controls and they significantly reduce after surgical cure. PHPT patients with low serum phosphate have a worse biochemical and clinical phenotype.

Background/Objectives: Managing type 2 diabetes mellitus (T2DM) and obesity requires a multidimensional, patient-centered approach including nutritional interventions (NIs) and physical activity. Changes in the gut microbiota (GM) have been linked to obesity and the metabolic alterations typical of T2DM and obesity, and they are strongly influenced by diet. However, few studies have evaluated the effects on the GM of a very-low-calorie ketogenic diet (VLCKD) in patients with T2DM, especially in the mid-term and long-term. This longitudinal study is aimed at evaluating the mid-term and long-term impact of the VLCKD and Mediterranean diet (MD) on the GM and on the anthropometric, metabolic, and lifestyle parameters of 11 patients with T2DM and obesity (diabesity). This study extends previously published results evaluating the short-term (three months) impact of these NIs on the same patients. Methods: At baseline, patients were randomly assigned to either a VLCKD (KETO group) or a Mediterranean diet (MEDI group). After two months, the KETO group gradually shifted to a Mediterranean diet (VLCKD-MD), according to current VLCKD guidelines. From the fourth month until the end of the study both groups followed a similar MD. Previous published results showed that VLCKD had a more beneficial impact than MD on several variables for 3 months of NI. In this study, the analyses were extended until six (T6) and twelve months (T12) of NI by comparing data prospectively and against baseline (T0). The GM analysis was performed through next-generation sequencing. Results: Improvements in anthropometric and metabolic parameters were more pronounced in the KETO group at T6, particularly for body mass index (−5.8 vs. −1.7 kg/m2; p = 0.006) and waist circumference (−15.9 vs. −5.2 cm; p = 0.011). At T6, a significant improvement in HbA1c (6.7% vs. 5.5% p = 0.02) and triglyceride (158 vs. 95 mg/dL p = 0.04) values compared to T0 was observed only in the KETO group, which maintained the results achieved at T3. The VLCKD-MD had a more beneficial impact than the MD on the GM phenotype. A substantial positive modulatory effect was observed especially up to the sixth month of the NI in KETO due to the progressive increase in bacterial markers of human health. After the sixth month, most markers of human health decreased, though they were still increased compared with baseline. Among them, the Verrucomicrobiota phylum was identified as the main biomarker in the KETO group, together with its members Verrucomicrobiae, Akkermansiaceae, Verrucomicrobiales, and Akkermansia at T6 compared with baseline. Conclusions: Both dietary approaches ameliorated health status, but VLCKD, in support of the MD, has shown greater improvements on anthropometric and metabolic parameters, as well as on GM profile, especially up to T6 of NI.

Abstract Purpose Gestational obesity (GO) presents a multifaceted challenge to maternal and fetal health, with an escalating prevalence and far-reaching consequences extending beyond pregnancy. This perspective statement by the Italian Society of Obesity (SIO) provides current insights into the diagnosis, maternal and fetal impacts, and treatment strategies for managing this pressing condition. Methods This article provides a comprehensive review of the maternal and fetal effects of GO and provides suggestions on strategies for management. Comprehensive review was carried out using the MEDLINE/PubMed, CINAHL, EMBASE, and Cochrane Library databases. Results The diagnosis of GO primarily relies on pre-pregnancy body mass index (BMI), although standardized criteria remain contentious. Anthropometric measures and body composition assessments offer valuable insights into the metabolic implications of GO. Women with GO are predisposed to several health complications, which are attributed to mechanisms such as inflammation and insulin resistance. Offspring of women with GO face heightened risks of perinatal complications and long-term metabolic disorders, indicating intergenerational transmission of obesity-related effects. While nutritional interventions are a cornerstone of management, their efficacy in mitigating complications warrants further investigation. Additionally, while pharmacological interventions have been explored in other contexts, evidence on their safety and efficacy specifically for GO remains lacking, necessitating further investigation. Conclusion GO significantly impacts maternal and fetal health, contributing to both immediate and long-term complications. Effective management requires a multifaceted approach, including precise diagnostic criteria, personalized nutritional interventions, and potential pharmacological treatments. These findings underscore the need for individualized care strategies and further research to optimize outcomes for mothers and their offspring are needed. Enhanced understanding and management of GO can help mitigate its intergenerational effects, improving public health outcomes. Level of evidence: Level V narrative review.

Background: SARS-CoV-2 pandemic resulted in lifestyle change of world’s population because of the measures adopted by governments to contain the virus spread. Design and Methods: This study examined whether lockdown impacted anthropometric indices, Mediterranean Diet (MD) adherence, Physical Activity Level (PAL), and Quality of Life (SF-12) in a cohort of 116 patients (96 F, aged 57.2 ± 13.1 years) affected by thyroid disorders. Before lockdown, data were collected during the endocrinological examination; after lockdown they were collected through a tele-phone interview (via video call). Results: Data revealed an overweight condition in 59% of patients, with no significant differences between the two observations (BMI values: 26.5 ± 4.9 vs 26.6 ± 4.9 kg/m2), whereas waist circumference values significantly increased over time (93.3 ± 12.6 vs 94.4 ± 12.5 cm; p = 0.003). Moreover, a lower adherence to the MD (PREDIMED score: 7.3 ± 1.8 vs 7.0 ± 1.8; p = 0.003) and a significant increase of sitting time (6.4 ± 3.2 h/die vs 9.0 ± 4.2; p < 0.001) were observed. A not significant decrease in PAL, which revealed a sedentary condition in pre- and post-lockdown (648 and 562 METs/week respectively), was found. The SF-12 score did not show relevant changes between the two observations. Conclusion: Our study highlights that patients with thyroid diseases are often sedentary and exhibit a high prevalence of over-weight, underscoring the need for a systematic anthropometric evaluation and, at times, lifestyle interventions.

Several studies report that breast cancer survivors (BCS) tend to have a poor diet, as fruit, vegetable, and legume consumption is often reduced, resulting in a decreased intake of nutraceuticals. Moreover, weight gain has been commonly described among BCS during treatment, increasing recurrence rate and mortality. Improving lifestyle and nutrition after the diagnosis of BC may have important benefits on patients' general health and on specific clinical outcomes. The Mediterranean diet (MD), known for its multiple beneficial effects on health, can be considered a nutritional pool comprising several nutraceuticals: bioactive compounds and foods with anti-inflammatory and antioxidant effects. Recent scientific advances have led to the identification of nutraceuticals that could amplify the benefits of the MD and favorably influence gene expression in these patients. Nutraceuticals could have beneficial effects in the postdiagnostic phase of BC, including helping to mitigate the adverse effects of chemotherapy and radiotherapy. Moreover, the MD could be a valid and easy-to-follow option for managing excess weight. The aim of this narrative review is to evaluate the recent scientific literature on the possible beneficial effects of consuming functional and nutraceutical foods in the framework of MD in BCS.

Obesity is a crucial health problem because it leads to several chronic diseases with an increased risk of mortality and it is very hard to reverse with conventional treatment including changes in lifestyle and pharmacotherapy. Bariatric surgery (BS), comprising a range of various surgical procedures that modify the digestive tract favouring weight loss, is considered the most effective medical intervention to counteract severe obesity, especially in the presence of metabolic comorbidities. The Enhanced Recovery After Bariatric Surgery (ERABS) protocols include a set of recommendations that can be applied before and after BS. The primary aim of ERABS protocols is to facilitate and expedite the recovery process while enhancing the overall effectiveness of bariatric procedures. ERABS protocols include indications about preoperative fasting as well as on how to feed the patient on the day of the intervention, and how to nourish and hydrate in the days after BS. This narrative review examines the application, the feasibility and the efficacy of ERABS protocols applied to the field of nutrition. We found that ERABS protocols, in particular not fasting the patient before the surgery, are often not correctly applied for reasons that are not evidence-based. Furthermore, we identified some gaps in the research about some practises that could be implemented in the presence of additional evidence.

Obesity is a severe health problem linked to an increased risk of comorbidity and mortality and its etiopathogenesis includes genetic, epigenetic, microbiota composition, and environmental factors, such as dietary habits. The olfactory system plays an important role in controlling food intake and meal size, influencing body weight and energy balance. This study aims to identify the connection between olfactory function and clinical and nutritional aspects related to weight excess in a group of 68 patients with overweight or obesity. All participants underwent the evaluation of olfactory function, anthropometric data (weight, height, BMI, waist circumference), clinical data (hypertension, disglycemia, dyslipidemia, metabolic syndrome), and adherence to the Mediterranean diet (Mediterranean Diet Score). A fourth-generation artificial neural network data mining approach was used to uncover trends and subtle associations between variables. Olfactory tests showed that 65% of patients presented hyposmia. A negative correlation was found between olfactory scores and systolic blood pressure, fasting plasma glucose, and triglycerides levels, but a positive correlation was found between olfactory scores and the Mediterranean diet score. The methodology of artificial neural networks and the semantic connectivity map “Auto-Contractive Map” highlighted the underlying scheme of the connections between the variables considered. In particular, hyposmia was linked to obesity and related metabolic alterations and the male sex. The female sex was connected with normosmia, higher adherence to the Mediterranean diet, and normal values of blood pressure, lipids, and glucose levels. These results highlight an inverse correlation between olfactory skills and BMI and show that a normosmic condition, probably because of greater adherence to the Mediterranean diet, seems to protect not only from an excessive increase in body weight but also from associated pathological conditions such as hypertension and metabolic syndrome.

Physical exercise has been shown to improve dysmetabolism in older adults, reducing cardiovascular risk, while its role in preventing dysmetabolism is less known. Moreover, most of the trials use exercise programs that are difficult to put into daily practice. The purpose of this Randomized Controlled Trial (RCT) was to evaluate the effectiveness of a 3-month moderate exercise program in improving or preventing dysmetabolism in 120 older adults, randomly selected for the exercise program (experimental group) or cultural activities (control group). None of the subjects were following a hypocaloric diet, and all of them reported healthy eating habits. Anthropometric (Body Mass Index (BMI) and Waist Circumference (WC)) and metabolic variables (fasting plasma glucose (FPG), High-Density Lipoprotein Cholesterol (HDL-C), and triglycerides (TG)) were assessed at baseline (T0) and at the end of the trial (T1). Dysmetabolism was defined by the presence of an increased WC plus at least two metabolic alterations. At T0, the two groups did not differ by sex, age, education, BMI, WC, FPG, HDL-C levels, and prevalence of dysmetabolism. The mean BMI value indicated overweight, and WC values were higher than the cut-off. At T1, a slight reduction in the number of people with dysmetabolism was found only in the experimental group. However, none of the individuals without dysmetabolism at T0 in the experimental group developed it at T1, while 11.4% developed it in the control group (p = 0.032). This study highlights that a moderate exercise program, accessible in daily practice, can prevent dysmetabolism in older adults, even while being overweight, while if dysmetabolism is already present, more prolonged combined nutritional and exercise interventions will be needed.

Purpose It is well known that interferon-α (IFN-α), used for long time as the main therapy for HCV-related disease, induces thyroid alterations, but the impact of the new direct-acting antivirals (DAAs) on thyroid is not established. Aim of this prospective study was to evaluate if DAAs therapy may induce thyroid alterations. Methods A total of 113 HCV patients, subdivided at the time of the enrollment in naïve group ( n = 64) and in IFN-α group ( n = 49) previously treated with pegylated interferon-α and ribavirin, were evaluated for thyroid function and autoimmunity before and after 20–32 weeks of DAAs. Results Before starting DAAs, a total of 8/113 (7.1%) patients showed Hashimoto's thyroiditis (HT) all belonging to IFN-α group (8/49, 16.3%), while no HT cases were found in the naïve group. Overall, 7/113 (6.2%) patients were hypothyroid: 3/64 (4.7%) belonging to naïve group and 4/49 (8.2%) to IFN-α group. Furthermore, a total of 8/113 patients (7.1%) showed subclinical hyperthyroidism: 2/64 (3.1%) were from naïve group and 6/49 (12.2%) from IFN-α group. Interestingly, after DAAs therapy, no new cases of HT, hypothyroidism and hyperthyroidism was found in all series, while 6/11 (54.5%) patients with non-autoimmune subclinical thyroid dysfunction became euthyroid. Finally, the only association between viral genotypes and thyroid alterations was genotype 1 and hypothyroidism. Conclusions This study supports evidence that DAAs have a limited or missing influence on thyroid in patients with HCV-related diseases. Moreover, it provides preliminary evidence that subclinical non-autoimmune thyroid dysfunction may improve after HCV infection resolution obtained by DAAs.

After a low-calorie diet, only 25% of patients succeed in maintaining the result of weight loss for a long time. This systematic review and meta-analysis aims to explore whether patients undergoing intensive intervention during the maintenance phase have a greater preservation of the weight achieved during the previous slimming phase than controls. A bibliographic search was conducted using PubMed, Scopus, and Cochrane databases for clinical trials and randomised, controlled trials investigating the role of choice in weight-loss-maintenance strategies. Only studies with a follow-up of at least 12 months were considered. A total of eight studies, for a total of 1454 patients, was identified, each comparing a group that followed a more intensive protocol to a control group. Our metanalysis highlighted that an intensive approach even in the maintenance phase could be important to ensure greater success in the phase following the weight-loss period. However, it should be pointed out that the improvement was not so different from the trend of the respective controls, with a non-statistically significant mean difference of the effect size (0.087; 95% CI −0.016 to 0.190 p = 0.098). This finding, along with the observation of a weight regain in half of the selected studies, suggests this is a long work that has to be started within the weight-loss phase and reinforced during the maintenance phase. The problem of weight control in patients with obesity should be understood as a process of education to a healthy lifestyle and a balanced diet to be integrated in the context of a multidisciplinary approach.

To verify if lethality and diffusivity of Covid-19 correlated with percentage of people vaccinated in different countries and whether results on these indicators were comparable under different types of vaccines. A linear regression analysis was conducted between vaccines/inhabitant, new cases/inhabitants and ratio deaths/cases. A comparison between the three indicators was carried out in countries subdivided by kind of vaccine. The proportion of vaccinations/inhabitants correlates negatively with proportion of deaths × 100 cases ( R = −3.90, p < 0.0001), but didn’t on incidence of new cases. Countries with prevalence of mRNA vaccines were similar to others on incidence of new cases; but a lower lethality of Sars-Cov2 was found than in countries with prevalence of viral vehicle vaccines ( F = 6.064, p = 0.0174) but didn’t against countries with prevalence of inactivated vaccines. The higher is the proportion of vaccine/inhabitant in a given country, the less is the fraction of infected people who die.

Background: Chronic Pain (CP) is a crucial determinant for disability in older adults. CP amplifies the impact of other common age-related diseases and increases cardiovascular risk. Physical exercise can improve CP. Randomized Controlled Trials (RCTs) with high-intensity exercise in older adults excluded people with Moderate Chronic Illness (MCI) and CP. Objective: This study aimed at evaluating in an RCT whether moderate exercise training can improve chronic pain in a sample of older adults, including people with MCI, and if any modification persists over time. Methods: A sample of 120 older adults was randomly selected for a moderate-intensity exercise program or cultural activities (control group). Chronic pain was assessed at t0, at t12 (end of the trial), and t48 weeks, by means of the Italian version of the SIP-Roland Scale. Results: Seventy-nine participants completed the follow-up (age 72.3±4.7, women 55.3%). At the end of RCT, an improvement in the SIP scale score was found in the exercise group (p=0.035), showing a lower score than the control group; this difference was not maintained at 48 weeks (p=0.235). Conclusion: Our study highlighted that a moderate-intensity exercise intervention reduced chronic pain in older adults, but this effect disappeared at follow-up after 36 weeks from the end of the training program. These findings suggested that such kinds of programs, easily accessible to old people even with MCI, should be implemented and supported over time, thus promoting active aging and preventing CP of age-related diseases.

Background Hidradenitis Suppurativa is a chronic inflammatory skin disease with a strong negative impact on physical and psychological health. Obesity, especially visceral adiposity, but also smoking or unhealthy nutritional habits, have been reported to be significantly associated with hidradenitis suppurativa. Design and methods Case-control study in 35 patients of both sexes affected with hidradenitis suppurativa, and 35 healthy subjects matched for sex, age, and geographic origin (Sardinia, Italy). Results Several anthropometric measures (body mass index, waist circumference, body composition), lifestyle (Mediterranean diet adherence, and physical activity level), and the perceived physical and mental health status were evaluated in case and controls. Hidradenitis patients showed significantly higher values of body mass index, waist circumference, body composition, fat mass, and lower values of physical and mental health status compared to controls, while both groups showed a similar moderate physical activity level which can be assumed to counteract the negative effects of obesity or poor nutritional pattern in hidradenitis patients. However, none of the evaluated variables were correlated with the severity of the disease, assessed by means of the Hurley stage system or the Sartorius score. Instead, the Sartorius score showed a positive correlation with the duration of hidradenitis, mainly imputable to the diagnostic delay and the consequent long lasting inflammatory status. Conclusions Although nutritional factors and lifestyle can be important and modifiable factors in the hidradenitis suppurativa course, the detrimental effect of chronic inflammation and delayed management are clearly prevalent and heavily influence the disease burden.

Among people with ST-segment elevation myocardial infarction (STEMI), high alexithymia was associated with delay to hospital arrival. High alexithymia could be a determinant of early death in the long term after STEMI. People with STEMI who participated in a survey in 2011, was tested about the state of life in 2021. The sample was divided into two cohorts (cut-off: TAS-20≥61 in 2011). The relationship between possible death occurred and having high alexithymia was calculated by comparing the mortality after 10 years in the two cohorts through the Cox' proportional hazard model. Status in life was verified on 39.3% of the sample. No differences were found regarding age, sex, high alexithymia between individuals on whom it was possible to verify the state in life and in whose it was not. In 2021, among people having high alexithymia in 2011, a higher risk of early death was found (RR=5.75, CI 95% 1.116-29.637).
