RESUMO
TNF inhibitors (TNFi) have revolutionized the therapeutic management of various chronic immune-mediated inflammatory diseases. Despite their known benefits, these therapies are related to paradoxical adverse effects (PAEs), including paradoxical psoriasis (PP). Although the underlying mechanism remains somewhat unclear, some theories suggest that genetic factors, particularly certain single-nucleotide polymorphisms (SNPs), may play an important role. The present review aimed to research and analyze recent findings regarding the pathomechanisms involved in the appearance of PP and the association between various genetic factors and PP in individuals treated with TNFi. We performed a literature search and found that certain genes (IL23R, TNF, FBXL19, CTLA4, SLC12A8, TAP1) are strongly associated with the occurrence of PP in pediatric and adult patients during therapy with TNFi. The identification of the specific SNPs involved in the appearance of PP and other PAEs in patients treated with TNFi for various diseases and in different populations may later favor the recognition of those patients at a high risk of developing such adverse effects and could guide personalized therapeutic strategies in future years.

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.

Background This study aimed to establish the reliability and validity of the Anti-Fat Attitudes (AFA) questionnaire and the Beliefs About Obese Persons (BAOP) scale. Methodology A convenience sample of 257 students from three distinct sections of the University of Medicine and Pharmacy "Grigore T. Popa" Iasi (Medical Faculty, Nutrition and Dietetics, and Nursing) participated in an observational study. Construction validity was tested with exploratory factor analysis. The students completed a form containing sociodemographic data, the AFA questionnaire, and the BAOP scale. Weight and height were self-reported and used to determine the body mass index. Results The value of the Cronbach alpha coefficient for the AFA questionnaire indicated adequate internal consistency (0.862). The exploratory factor analysis identified the following three factors corresponding to the original questionnaire: Dislike, Fear of Fat, and Willpower. We validated a single-factor structure of the BAOP scale, which had adequate internal consistency (0.781). There were statistically significant differences (AFA: p = 0.02; BAOP: p = 0.03) between the scores of the students from Nutrition and Dietetics, Nursing, and General Medicine. Conclusions This study demonstrated that the AFA questionnaire and the BAOP scale could be used to evaluate weight stigma in healthcare students, providing a useful tool to assess the effects of weight stigma awareness interventions in this population.
RESUMO
Type 2 diabetes mellitus (T2DM) has become a global epidemic. To effectively control T2DM, individuals must adhere to a high-quality diet that encompasses not only healthy dietary patterns but also promotes positive eating behaviors. We conducted a cross-sectional study on 314 patients with T2DM, and we evaluated the diet quality and also examined the associations between eating behavior, diet quality, and anthropometric and clinical factors in T2DM patients. We used the Diet Quality Index-International and Dutch Eating Behavior Questionnaire to assess dietary characteristics. We found that women had a significantly higher diet quality than men (61.40 vs. 58.68, p = 0.002) but were also more prone to emotional eating (2.00 vs. 1.53, p < 0.001) and restrained eating (2.39 vs. 2.05, p = 0.002). Restrained eating correlated with duration of diabetes (r = -0.169, p = 0.003), body mass index (r = 0.182, p = 0.001), and external eating with glycated hemoglobin (r = 0.114, p = 0.044). Patients with emotional eating had a higher vitamin C adequacy score (ß = 0.117, p = 0.045). External eating was positively associated with grain adequacy (ß = 0.208, p < 0.001) and negatively associated with empty-calorie food moderation score (ß = -0.125, p = 0.032). For restrained eating, we found associations with vitamin C adequacy (ß = -0.138, p = 0.017) and fruit adequacy (ß = 0.125, p = 0.033). In conclusion, the results of this study provide valuable insight into dietary behavior and emphasize the importance of promoting healthy eating habits for T2DM patients.

Healthy dietary patterns during pregnancy are crucial for ensuring maternal and foetal health outcomes. Numerous methodologies exist for assessing the diet of pregnant women, including dietary patterns and various appraisal tools of diet quality. This study aimed to assess the dietary patterns and diet quality of pregnant women and to investigate the relationship between dietary patterns, diet quality estimators, and the adequacy of nutrient intake. EPIC FFQ was applied to a sample of 251 pregnant women, and questionnaires were interpreted with the FETA program. Dietary patterns were then determined by means of principal component analysis. Our results showed a substantial association between dietary patterns and total diet quality, as measured by the Diet Quality Index for Pregnancy (DQI-Pc), PURE Healthy Diet Score, and FIGO Diet Quality Score. We also found correlations between certain dietary patterns and particular nutrient intakes recommended by the European Food Safety Authority during pregnancy. The most deficient intake was registered for iron (86.1%), zinc (87.3%) and magnesium (79.3%), posing a threat to normal bone development, anaemia prophylaxis, and immune status. These results highlight the importance of assessing and understanding eating habits during pregnancy in order to achieve optimal outcomes for both the mother and the foetus.

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.

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.

Modern lifestyles have led to sedentary behavior, lower participation in active movement and physical activities during leisure time, unhealthy diets, and increased exposure to stress. It is important to examine the interaction of several lifestyle risk factors instead of focusing on one alone. The purpose of this study was to identify lifestyle patterns in a group of patients with type 2 diabetes and the associations of its components with certain metabolic parameters. Using principal component analysis, we identified three dietary patterns: the prudent pattern (fat, oil, cereals, potatoes, vegetables, fish, nuts, seeds and fruits), the Western pattern (meat and meat products, eggs and soft drinks) and the traditional pattern (milk and its derivatives, soups and sauces, with a low intake of sugar/snacks). In addition, using the same method of analysis, we identified two lifestyle patterns: the inadequate lifestyle pattern (Western dietary pattern, increased hours of sleep and lower levels of stress) and the traditional lifestyle pattern (traditional dietary pattern, increased physical activity (PA) and non-smoking status). The inadequate lifestyle pattern was associated with younger age, hypertension and diabetic neuropathy. The traditional lifestyle pattern was related to lower postprandial blood glucose levels. Sedentary individuals were more likely to be over 65 years old and to have higher glycated hemoglobin (HbA1c). Smokers were also more likely to have inadequate glycemic and lipid profile control.
RESUMO
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.

(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.
RESUMO
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.
RESUMO
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.
RESUMO
Hepatic diseases pose a significant public health concern. Regardless of the severity of hepatic fibrosis, treatment is recommended for all chronic hepatitis C virus (HCV) subjects. However, fibrosis and steatosis assessment remains crucial for evaluating the prognosis, progression, and hepatic disease monitoring, particularly following the treatment with direct-acting antivirals (DAAs). The aim of our study was to evaluate the impact of metabolic factors and the extent of hepatic fibrosis and fat accumulation in chronic HCV infection subjects. Additionally, another objective was to investigate modifications regarding fibrosis and steatosis three months after a successful sustained viral response (SVR). A total of 100 patients with compensated cirrhosis and chronic hepatitis C (CHC) were included in our study. These patients received treatment with DAA and underwent Fibromax assessment before and three months post SVR. After DAA treatment, a significant decrease was observed in the degree of hepatic fibrosis and hepatic steatosis. This regression was evident three months following the achievement of SVR. Chronic viral hepatitis C may trigger risk factors for metabolic syndromes, such as obesity and type 2 diabetes mellitus. Conclusions: It is crucial to monitor metabolic factors and take timely measures to prevent or treat metabolic syndrome in patients with chronic viral hepatitis C.
RESUMO
(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.

We conducted a narrative review on the interaction between dietary patterns with demographic and lifestyle variables in relation to health status assessment. The food pattern has the advantage of taking into account the correlations that may exist between foods or groups of foods, but also between nutrients. It is an alternative and complementary approach in analysing the relationship between nutrition and the risk of chronic diseases. For the determination of dietary patterns one can use indices/scores that evaluate the conformity of the diet with the nutrition guidelines or the established patterns (a priori approach). The methods more commonly used are based on exploratory data (a posteriori): cluster analysis and factor analysis. Dietary patterns may vary according to sex, socio-economic status, ethnicity, culture and other factors, but more, they may vary depending on different associations between these factors. The dietary pattern exerts its effects on health in a synergistic way or even in conjunction with other lifestyle factors, and we can therefore refer to a 'pattern of lifestyle'.

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.

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.

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.

OBJECTIVES: To evaluate the rate of morbidity and mortality associated with colorectal polyps after the next 8-years period of endoscopic polypectomy, in a high risk managed care population. MATERIAL AND METHOD: Cohorts of 77 subjects with benign neoplasms were identified with a colonoscopy in 1999. Three groups of subjects: benign neoplasms with polypectomy, benign neoplasms without polypectomy, and no neoplasms were evaluated. Five years recurrence rates (1999-2004) of benign or new malignant colorectal neoplasms were identified: for the benign determined for the baseline benign neoplasms with polypectomy and no neoplasm groups neoplasm without polypectomy, only rates for malignancy were observed. Malignancy was evaluated with immunohistochemical p53 (tumor protein 53) and PCNA (Proliferating Cell Nuclear Antigen) staining pattern. Over the next 8 years 2004-2012 were evaluated the mortality and the recurrence rate of the benign polyps. RESULTS: 77 subjects were enrolled in our study; 71.4% were diagnosed with benign and 2.5% with malignant neoplasms. The 5-years cumulative incidence rates of malignant colorectal neoplasms in the no neoplasm (n = 20) and benign neoplasm groups (n = 55) were (n = 1) 5% and ( n = 10) 18.1%, respectively (p < 0.005). A lower 5-years malignancy rate was observed in benign neoplasms group with polypectomy (12%) compared to the benign neoplasm group without polypectomy (33.3%) (p < 0.05). The 8-years mortality rate was compared into benign recurrent polyps group and into malign group: the lower 8-years mortality rate was observed into benign polyp no neoplasm group (0%) and into benign recurrent polyps group (40%); the highest rate was observed into neoplasm group (100%). CONCLUSIONS: The high recurrence rate of benign colorectal neoplasms and a higher incidence of colorectal cancer in subjects at high risk-history of benign colorectal neoplasm-highlight a healthcare opportunity for surveillance and/or interventions to reduce the morbidity associated with colorectal neoplasms.

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.
