Understanding the Interplay of Dietary Intake and Eating Behavior in Type 2 Diabetes.

Diet and eating behavior both play a crucial role in the prevention and management of type 2 diabetes mellitus (T2DM). The main objective of this study was to investigate the relationship between dietary intake and eating behavior in a population of patients with T2DM. A cross-sectional study was performed using 416 patients with T2DM and their dietary intake and eating behavior were assessed with validated questionnaires. Women scored significantly higher than men for emotional and restrained eating (p < 0.001). Correlation analyses showed that emotional eaters consumed significantly more calories (r = 0.120, p = 0.014) and fat (r = 0.101, p = 0.039), as well as non-alcoholic beverages for women (r = 0.193, p = 0.003) and alcohol for men (r = 0.154, p = 0.038). Also, individuals who ate based on external cues consumed significantly more calories (r = 0.188, p < 0.001) and fat (r = 0.139, p = 0.005). These results demonstrate that eating behavior influences dietary intake. Understanding this relationship could optimize diabetes management and allow for more individualized nutritional guidance.

Exploring Lifestyle and Dietary Patterns in Pregnancy and Their Impact on Health: A Comparative Analysis of Two Distinct Groups 10 Years Apart.

The significance of dietary patterns during pregnancy is highlighted by accumulating evidence, emphasizing their pivotal role in promoting a healthy pregnancy for both the mother and the child. This study aimed to assess the current dietary patterns of pregnant women, compare the energy and nutrient intake of two distinct groups with a 10-year interval, and identify changes in dietary patterns. EPIC FFQ was applied, and its data were interpreted with the FETA program version 6 (CAMB/PQ/6/1205). By means of principal component analysis, three different food patterns were identified in each study group: vegetarian, balanced, and traditional (2013); and prudent, vegetarian, and modern (2023). Analyzing the relationship between food groups and gestational weight, we found that gestational weight gain in 2013 was positively correlated with eggs and egg dishes and milk and milk products, whereas in 2023, gestational weight gain was positively correlated with fats and oils, non-alcoholic beverages, and the modern pattern. Additionally, in 2023, pre-gestational BMI correlated positively with eggs and egg dishes. The balanced pattern emerged as a predictor for a lower likelihood of inadequate gestational weight gain in both groups. Furthermore, normal and overweight pregnant women showed a reduced likelihood of excessive gestational weight gain.

Survival Prediction in Diabetic Foot Ulcers: A Machine Learning Approach.

Our paper proposes the first machine learning model to predict long-term mortality in patients with diabetic foot ulcers (DFUs). The study includes 635 patients with DFUs admitted from January 2007 to December 2017, with a follow-up period extending until December 2020. Two multilayer perceptron (MLP) classifiers were developed. The first MLP model was developed to predict whether the patient will die in the next 5 years after the current hospitalization. The second MLP classifier was built to estimate whether the patient will die in the following 10 years. The 5-year and 10-year mortality models were based on the following predictors: age; the University of Texas Staging System for Diabetic Foot Ulcers score; the Wagner-Meggitt classification; the Saint Elian Wound Score System; glomerular filtration rate; topographic aspects and the depth of the lesion; and the presence of foot ischemia, cardiovascular disease, diabetic nephropathy, and hypertension. The accuracy for the 5-year and 10-year models was 0.7717 and 0.7598, respectively (for the training set) and 0.7244 and 0.7087, respectively (for the test set). Our findings indicate that it is possible to predict with good accuracy the risk of death in patients with DFUs using non-invasive and low-cost predictors.

Evaluating Classification Systems of Diabetic Foot Ulcer Severity: A 12-Year Retrospective Study on Factors Impacting Survival.

(1) Background: This study examines the survival of patients after their first presentation with diabetic foot ulcers (DFUs) to the regional Diabetes, Nutrition, and Metabolic Diseases Clinic within the Emergency Clinical Hospital "Sf. Spiridon", Iasi, and analyzes the factors associated with this outcome. (2) Methods: In this retrospective study, patients with DFUs consecutively referred between 1 January 2007 and 31 December 2017 were followed up until 31 December 2020 (for 13 years). The study group included 659 subjects. (3) Results: During the study period, there were 278 deaths (42.2%) and the average survival time was 9 years. The length of hospitalization, diabetic nephropathy, chronic kidney disease, glomerular filtration rate, cardiovascular disease, hypertension, anemia, and DFU severity were the most significant contributors to the increase in mortality. Patients with severe ulcers, meaning DFUs involving the tendon, joint, or bone, had a higher mortality risk than those with superficial or pre-ulcerative lesions on initial presentation (Texas classification HR = 1.963, 95% CI: 1.063-3.617; Wagner-Meggitt classification HR = 1.889, 95% CI: 1.024-3.417, SINBAD Classification System and Score HR = 2.333, 95% CI: 1.258-4.326) after adjusting for confounding factors. (4) Conclusions: The findings of this study suggested that patients presenting with severe ulcers involving the tendon, joint, or bone exhibited a significantly higher risk of mortality, even when potential confounders were taken into consideration.

A Scoping Review of the Relationship between Intermittent Fasting and the Human Gut Microbiota: Current Knowledge and Future Directions.

Intermittent fasting (IF) has been promoted as an alternative to dietary caloric restriction for the treatment of obesity. IF restricts the amount of food consumed and improves the metabolic balance by synchronizing it with the circadian rhythm. Dietary changes have a rapid effect on the gut microbiota, modulating the interaction between meal timing and host circadian rhythms. Our paper aims to review the relationships between IF and human gut microbiota. In this study, the primary area of focus was the effect of IF on the diversity and composition of gut microbiota and its relationship with weight loss and metabolomic alterations, which are particularly significant for metabolic syndrome characteristics. We discussed each of these findings according to the type of IF involved, i.e., time-restricted feeding, Ramadan fasting, alternate-day fasting, and the 5:2 diet. Favorable metabolic effects regarding the reciprocity between IF and gut microbiota changes have also been highlighted. In conclusion, IF may enhance metabolic health by modifying the gut microbiota. However additional research is required to draw definitive conclusions about this outcome because of the limited number and diverse designs of existing studies.

From the Sun to the Cell: Examining Obesity through the Lens of Vitamin D and Inflammation.

Obesity affects more than one billion people worldwide and often leads to cardiometabolic chronic comorbidities. It induces senescence-related alterations in adipose tissue, and senescence is closely linked to obesity. Fully elucidating the pathways through which vitamin D exerts anti-inflammatory effects may improve our understanding of local adipose tissue inflammation and the pathogenesis of metabolic disorders. In this narrative review, we compiled and analyzed the literature from diverse academic sources, focusing on recent developments to provide a comprehensive overview of the effect of vitamin D on inflammation associated with obesity and senescence. The article reveals that the activation of the NF-κB (nuclear factor kappa B subunit 1) and NLRP3 inflammasome (nucleotide-binding domain, leucine-rich-containing, pyrin domain-containing-3) pathways through the toll-like receptors, which increases oxidative stress and cytokine release, is a common mechanism underlying inflammation associated with obesity and senescence, and it discusses the potential beneficial effect of vitamin D in alleviating the development of subclinical inflammation. Investigating the main target cells and pathways of vitamin D action in adipose tissue could help uncover complex mechanisms of obesity and cellular senescence. This review summarizes significant findings related to opportunities for improving metabolic health.

Validation of the Dutch Eating Behavior Questionnaire in a Romanian Adult Population.

(1) Background: Obesity, part of the triple global burden of disease, is increasingly attracting research on its preventive and curative management. Knowledge of eating behavior can be useful both at the individual level (to individualize treatment for obesity) and the population level (to implement more suitable food policies). The Dutch Eating Behavior Questionnaire (DEBQ) is a widely used international tool to assess eating behavior, i.e., emotional, external and restricted eating styles. The aim of this study was to validate the Romanian version of DEBQ, as obesity is a major concern in Romania. (2) Methods: Our study tested the psychometric properties of the Romanian version of DEBQ on an adult population and explored the associations of eating behavior with weight status (3) Results: The study showed a factor load similar to the original version of the questionnaire and a very good internal validity (Cronbach's alpha fidelity coefficient greater than 0.8 for all scales of the questionnaire) for the Romanian version of DEBQ and showed that all of the scales positively correlated with body mass index in both men and women. (4) Conclusions: This study will enable the use of the DEBQ Romanian version on the adult population of Romania where the findings could be incorporated into developing better strategies to reduce the burden of nutrition-related diseases.

Role of PNPLA3 in the Assessment and Monitoring of Hepatic Steatosis and Fibrosis in Patients with Chronic Hepatitis C Infection Who Achieved a Sustained Virologic Response.

Background and Objectives: Hepatic diseases are an important public health problem. All patients with chronic hepatitis C virus (HCV) infection receive treatment, regardless of hepatic fibrosis severity. However, evaluation of hepatic fibrosis and steatosis is still useful in assessing evolution, prognosis and monitoring of hepatic disease, especially after treatment with direct-acting antivirals (DAAs). The aim of this study was to assess the link between patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism and the degree of hepatic steatosis and fibrosis in patients with chronic HCV infection, as well as changes in steatosis and fibrosis three monthsafter obtaining a sustained viral response (SVR). Materials and Methods:Ourstudy included 100 patients with chronic hepatitis C (CHC) infection and compensated cirrhosis who received DAA treatment and who were evaluated using Fibromax prior to and 3 months after SVR. The influence of PNPLA3 (CC, CG, GG) genotype among these patients on the degree of post-treatment regression of steatosis and fibrosis was assessed. Results: Regression was noticed in the degree of both hepatic steatosis and hepatic fibrosis post-DAA treatment (three months after SVR). Analysis of the correlation between PNPLA3 genotype and fibrosis indicated that the average level of fibrosis (F) before DAA treatment was higher in patients with the GG genotype than in patients with the CC or CG genotype. Three months after SVR, the average level of fibrosis decreased; however, it remained significantly increased in GG subjects compared to that in CC or CG patients. The degree of hepatic steatosis before treatment was not significantly different among patients with different PNPLA3 genotypes, and no significant correlations were observed three months after SVR. Conclusions: The genetic variants of PNPLA3 influence the evolution of hepatic fibrosis. The GG subtype plays an important role in the degree of hepatic fibrosis both before and after treatment (three months after SVR)and could be a prognostic marker for assessment of post-SVR evolution.

Correlations between PNPLA3 Gene Polymorphisms and NAFLD in Type 2 Diabetic Patients.

Background and Objectives: Non-alcoholic fatty liver disease is a worldwide significant public health problem, particularly in patients with type 2 diabetes mellitus. Identifying possible risk factors for the disease is mandatory for a better understandingand management of this condition. Patatin-like phospholipase domain-containing protein 3 (PNPLA3) has been linked to the development and evolution of fatty liver but not to insulin resistance. The aim of this study isto evaluate the relationships between PNPLA3 and fatty liver, metabolic syndrome and subclinical atherosclerosis. Materials and Methods: The study group consisted of patients with type 2 diabetes mellitus without insulin treatment. The degree of liver fat loading was assessed by ultrasonography, and subclinical atherosclerosis was assessed using carotid intima-media thickness (CIMT). PNPLA3 rs738409 genotype determination was performed by high-resolution melting analysis that allowed three standard genotypes: CC, CG, and GG. Results: Among the 92 patients, more than 90% showed various degrees of hepatic steatosis, almost 62% presented values over the normal limit for the CIMT. The majority of the included subjects met the criteria for metabolic syndrome. Genotyping of PNPLA3 in 68 patients showed that the difference between subjects without steatosis and subjects with hepatic steatosis was due to the higher frequency of genotype GG. The CC genotype was the most common in the group we studied and was significantly more frequent in the group of subjects with severe steatosis; the GG genotype was significantly more frequent in subjects with moderate steatosis; the frequency of the CG genotype was not significantly different among the groups.When we divided the group of subjects into two groups: those with no or mild steatosis and those with moderate or severe steatosis it was shown that the frequency of the GG genotype was significantly higher in the group of subjects with moderate or severe steatosis. PNPLA3 genotypes were not associated with metabolic syndrome, subclinical atherosclerosis, or insulin resistance. Conclusions: Our results suggest that PNPLA3 does not independently influence cardiovascular risk in patients with type 2 diabetes mellitus. The hypothesis that PNPLA3 may have a cardioprotective effect requires future confirmation.

The influence of obstructive sleep apnea syndrome on anthropometric parameters at 12 months after laparoscopic sleeve gastrectomy.

The aim of this study was to assess the influence of obstructive sleep apnea syndrome (OSAS) on the change in anthropometric parameters and body composition, in patients undergoing laparoscopic sleeve gastrectomy (LSG). This prospective study included patients undergoing LSG who had pre-operative polysomnography data and were also evaluated at six and 12 months after surgery. All patients included also had whole body composition analysis data before surgery and at six and 12 months after surgery. The results are presented in comparison between patients with and without OSAS. We included 73 patients in the analysis with a mean ± SD age and body mass index (BMI) of 40.3 ± 10.9 years and 45.4 ± 6.3 kg/m2, respectively. As compared to the baseline levels, at 6 months there was a significant decrease in BMI, weight, waist circumference, serum glucose and HbA1c. At 12 months there was no further decrease as compared to the 6 months levels, irrespective of OSAS status. We observed a significant decrease at 6 months in percentage of fat, in both types of patients. However, as compared to the 6 months levels, at 12 months the percent fat had a significant decrease only in patients without OSAS (- 4.6%, 95% CI - 7.6 to - 1.7%) and not in those with OSAS (- 2.2%, 95% CI - 4.5 to 0.2%). In our study, patients with OSAS showed a similar decrease in different anthropometric parameters as those without OSAS after LSG. However, at 12 months of follow-up there was a significant decrease in the percent fat only in patients without OSAS.

Ghrelin-producing cells distribution in the stomach and the relation with Helicobacter pylori in obese patients.

OBJECTIVE: Ghrelin is believed to influence weight evolution after bariatric surgery. Helicobacter pylori (H. pylori) infection may influence ghrelin plasma levels by affecting the ghrelin-producing cells (GPC) in the stomach. The purpose of the study was to characterize the GPC distribution in the stomach in overweight patients and the influence of H. pylori infection on them. PATIENTS, MATERIALS AND METHODS: The study group included 21 obese patients undergoing bariatric surgery with ghrelin levels and anti-H. pylori antibodies previously measured, and upper gastrointestinal endoscopy with histological evaluation of H. pylori infection performed. Immunohistochemical expression of ghrelin was quantified in gastric resection specimens. RESULTS: The results showed a higher number of GPC in the obese women than in men (p>0.05). The highest number of GPC was detected in the gastric body, followed by the fundus and antral region (p<0.001). GPC number correlated inversely with anthropometric parameters: weight (p=0.011), body mass index (BMI) (p=0.017), waist circumference (WC) (p=0.066) was lower in patients with H. pylori infection (p>0.05) or gastritis (p>0.05), the number decreasing with the increase in depth of gastritis lesion (p>0.05). CONCLUSIONS: The present study fulfills the characterization of GPC in obese patients, showing a higher number in women than in men, their predominant location in the gastric body, and their relationship with the anthropometric parameters (weight, BMI, WC), H. pylori infection and gastritis lesions. These results open broad perspectives for a deeper understanding of the ghrelin involvement in the obesity pathogenic mechanism, associated or not with other gastric conditions.

Effects of ghrelin in energy balance and body weight homeostasis.

Ghrelin is a gut peptide composed of 28 amino acids mostly secreted in the gastric fundus mucosa. It was isolated and described in 1999 by Kojima et al. and only three years later its specific receptor, GHSR1a, was also identified. Ghrelin, the endogenous ligand for the GH secretagogue receptor, is the only peripheral orexigenic hormone that activates the receptors to be found especially in the appetite center (hypothalamus and pituitary gland). Ghrelin is present in human plasma in two forms: an inactive form known as deacylated ghrelin, and an active form called acylated ghrelin synthesized under the action of ghrelin O-acyltransferase enzyme (GOAT). The literature even mentions an extremely complex ghrelin/GOAT/GHSR system involved in the regulation of human energy, metabolism and adaptation of energy homeostasis to environmental changes. In humans, there is a preprandial rise and a postprandial fall in plasma ghrelin levels, which strongly suggest that the peptide plays a physiological role in meal initiation and may be employed in determining the amount and quality of ingested food. Besides the stimulation of food intake, ghrelin determines a decrease in energy expenditure and promotes the storage of fatty acids in adipocytes. Thus, in the human body ghrelin induces a positive energy balance, an increased adiposity gain, as well as an increase in caloric storage, seen as an adaptive mechanism to caloric restriction conditions. In the current world context, when we are witnessing an increasing availability of food and a reduction of energy expenditure to a minimum level, these mechanisms have become pathogenic. As a consequence, the hypothesis that ghrelin is involved in the current obesity epidemic has been embraced by many scholars and researchers.

Dietary Vitamin D, Calcium, and Magnesium Intake in Type 2 Diabetes Patients.

Aim: To estimate specific nutrient intake in patients with type 2 diabetes. Materials and Methods: The study was conducted on a group of subjects with type 2 diabetes. The collected data included: anthropometry, lifestyle, blood measurements, and the mean daily nutrient intake assessed by the EPIC food frequency questionnaire. Results: The study group included 101 subjects with type 2 diabetes mellitus (DM) with a mean age of 60.6±10 years, of which 45 men (59±10.6 years) and 56 women (62±9.6 years). The average energy intake was 1714.4±713.9 Kcal/day, with a statistically significant gender difference (1877.7±850.9 kcal/day for men, 1583.1±554.9 kcal/day for women, p = 0.039, and the average daily micronutrient intake was 2.44±1.44 µg/day for vitamin D, 724.5µ263.2 mg/day for Calcium (Ca), 266.7±98 mg/day for magnesium (Mg), which was low compared to dietary recommendations. Calcium intake was correlated with intake of carbohydrates, saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), fiber and energy. Vitamin D intake was correlated only with protein intake (R=0.695), while magnesium intake correlated with intake of fibers, energy, carbohydrates and SFA. Conclusions: Our study in patients with type 2 diabetes showed a reduced average intake of calcium, magnesium and vitamin D compared to standard recommendations, requiring an individualized approach.

The role of histological evaluation of Helicobacter pylori infection in obese patients referred to laparoscopic sleeve gastrectomy.

Helicobacter pylori (H. pylori) is the etiological factor for gastritis in more than half of the worldwide population. H. pylori infection increases the risk for gastric pathology, but could also have consequences on cardio-metabolic status. Obesity has as epidemic growth, and the only efficient long-term treatment for morbidly obese patients is currently surgery. Although of vital importance, the preoperative assessment is not standardized, including the aspects related to H. pylori infection. The aim of this prospective study was to evaluate the prevalence of H. pylori (Hp) infection in a group of patients referred to bariatric surgery and the agreement of two commonly used methods for its diagnosis. We included 70 asymptomatic obese patients consecutively for 14 months, who were evaluated by serology (anti-Hp IgG antibodies) and by histology (gastroscopy with gastric mucosa biopsy). If diagnosed, H. pylori infection was standard treated and afterwards, all patients underwent laparoscopic sleeve gastrectomy; the resected stomach was morphologically evaluated. 58.6% of patients were H. pylori positive on serology and 51.4% were H. pylori positive on histology, agreement coefficient factor kappa between the two methods being 0.686, p<0.001. The serological diagnosis had a sensibility of 90.3% and a specificity of 77.8%. The prevalence of H. pylori infection in the resected stomach was 11.4%, and was associated with more severe degrees of chronic gastritis. In conclusion, as gastroscopy should anyhow be performed in all patients referred to surgery, our data favor the histological evaluation in all patients and the eradication treatment according to its results.

Pathological aspects underlying pancreatogenous hyperinsulinemic hypoglycemia--report of three cases.

Pancreatogenous hyperinsulinemic hypoglycemia (PHH) is a rare disorder determined by an abnormally high secretion of insulin in the pancreas, in the absence of other medical or pharmacological factors. Either ß-cell tumors (insulinomas) or ß-cell hyperplasia (nesidioblastosis) can determine this pathology. Most publications on insulinomas or nesidioblastosis approached these subjects from a clinical point of view. This paper aims to analyze pathological aspects underlying pancreatogenous hyperinsulinemic hypoglycemia. We present two cases of insulinomas with unusual pancreatic localization and size, one of them showing amyloid deposits in the stroma. In both cases, immunohistochemistry confirmed the clinical and imagistic supposition. The third reported case refers to a 57-year-old patient with nesidioblastosis with isolated disposition of endocrine cells and areas of focal organization, both morphological aspects being extremely rare in adults. Although clinical and laboratory data are usually identical in the two forms of PHH, histopathological and immunohistochemical diagnosis is essential in differentiating insulinomas from nesidioblastosis, as the surgical management is different: enucleation for insulinomas and total or subtotal pancreatectomy for nesidioblastosis.

The evaluation of preoperative nutritional status in patients undergoing thoracic surgery.

AIM: The aim of this study was to assess the preoperative nutritional status of patients undergoing thoracic surgery using different nutritional tools. MATERIAL AND METHOD: . We conducted a prospective study on a sample of 43 thoracic patients, including 23 with neoplasms and 20 with non-neoplastic pathology who underwent thoracic surgery procedures between July-September 2011, in the Thoracic Surgery Clinic in Iasi. Weight and height were measured and body mass index (BMI) was calculated. WHO classification for BMI categories was used. Preoperative serum level of transthyretin (TTR) and demographic data (gender, age) were also assessed. All patients were examined by the Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002). RESULTS: After performing SGA, 67.9% of the patients were well-nourished, 21.4% were moderately or suspected of being malnourished and 10.7% were severely malnourished. The level of TTR was significantly lower in the moderately or severely malnourished group, compared to those considered well-nourished. According to NRS-2002, 42.9% of the patients were considered at nutritional risk. The level of TTR of these patients was lower than the level of TTR of the patients without nutritional risk, but without statistical significance. CONCLUSIONS: Subjective Global Assessment (SGA) and the Nutritional Risk Screening 2002 (NRS 2002) are useful in identifying patients with nutritional risk, so that appropriate nutritional management could be initialised even before surgery.

The role and interactions of ghrelin concerning the nutritional and inflammatory status.

Ghrelin is an important neuroendocrine peptide having as main purpose the stimulation of growth hormone (GH) secretion. It is also an important regulator of the long-term energy balance and short-term nutritional intake. Ghrelin has several other biological actions, among which the capacity to regulate gastrointestinal motility, to modulate the reproductive and stress axes as well as the glucose metabolism, and other well-defined actions within the cardiovascular and renal physiology. Due to its numerous effects, ghrelin is considered on one hand a potential target in the treatment of obesity and on the other, a therapeutic option in other dysfunctions and illnesses.
