RESUMO
In this analysis, we aimed to investigate the effect of COVID-19 disease on eating behavior. A total of 55 right-handed adults, <50 years of age, without overweight or obesity, from two cross-sectional studies were included. The first one enrolled subjects between September 2018 and December 2019 (non-COVID-19 group). The second one included subjects enrolled between March 2022 and May 2023; for this analysis, 28 with a history of COVID-19 (COVID-19 group) were retained. Hunger, TFEQ-18, plasma ghrelin, neuropeptide Y (NPY) and resting-state fMRI were assessed during fasting. Intraregional neuronal synchronicity and connectivity were assessed by voxel-based regional homogeneity (ReHo) and degree of centrality (DC). Significantly higher ghrelin and NPY levels were observed in the COVID-19 group than in the non-COVID-19 group (ghrelin 197.5 pg/mL vs. 67.1 pg/mL, p < 0.001; NPY 128.0 pg/mL vs. 84.5 pg/mL, p = 0.005). The NPY levels positively correlated with the DC and ReHo in the left lingual (r = 0.67785 and r = 0.73604, respectively). Similar scores were noted for cognitive restraint, uncontrolled eating and emotional eating in both groups according to the TFEQ-18 questionnaire results (p > 0.05 for all). Our data showed increased levels of appetite-related hormones, correlated with activity in brain regions involved in appetite regulation, persisting long after COVID-19 infection.

OBJECTIVE: The aim of this study was to evaluate the trends in the incidence of diabetic neuropathy (DN) and nondiabetic neuropathy (non-DN) in a hospital-based cohort between 2010 and 2019 in Romania. METHODS: We retrospectively analyzed cases with a primary or secondary discharge International Classification of Diseases, Tenth Revision, diagnosis code of neuropathy reported throughout Romania. RESULTS: A total of 1 725 729 hospitalizations with a diagnosis of neuropathy (DN, 769 324 - 44.6%, and non-DN, 956 405- 55.4%) were identified. Women accounted for more DN cases (40 0 936- 52.1%), and men accounted for more non-DN cases (63 7 968- 61.0%). The incidence rate showed an increasing trend during the index period, by a mean rate of 4.3%/year for non-DN and 1.4%/year for DN. Type 2 diabetes was responsible for the overall increase in the incidence rate of DN, whereas in type 1 diabetes, the incidence rate decreased; in both types of diabetes, diabetic polyneuropathy was predominant, whereas autonomic neuropathy had an incidence rate of 10 to 20 times lower than polyneuropathy. The incidence rates of non-DNs increased mainly due to inflammatory polyneuropathies (+3.8%) and uremic neuropathy (+10.3%). CONCLUSION: Using a nationally representative database of hospital-admitted cases, we found that the incidence rates of DN and non-DN increased from 2010 to 2019. The main contributors were type 2 diabetes, inflammatory polyneuropathy, and uremic neuropathy.
RESUMO
Background/Objectives: Lower extremity amputations (LEAs) are a burdensome complication of peripheral artery disease (PAD) and/or arterial embolism and thrombosis (AET). We assessed the trends in PAD- and/or AET-related LEAs in Romania. Methods: This retrospective study (2015-2019) analyzed data on minor and major LEAs in hospitalized patients recorded in the National School for Public Health, Management, and Health Education database. The absolute numbers and incidences of LEAs were analyzed by diagnosis type, year, age, sex, and amputation level. Results: Of 38,590 vascular disease-related amputations recorded nationwide, 36,162 were in PAD and 2428 in AET patients. The average LEA incidence in the general population was 34.73 (minimum: 31.96 in 2015; maximum: 36.57 in 2019). The average incidence of major amputations, amputations above the knee, hip amputations, amputations below the knee, and minor amputations was 16.21 (15.62 in 2015; 16.84 in 2018), 13.76 (13.33 in 2015; 14.28 in 2018), 0.29 (0.22 in 2017; 0.35 in 2019), 2.15 (2.00 in 2015; 2.28 in 2019), and 18.52 (16.34 in 2015; 20.12 in 2019), respectively. Yearly PAD- and/or AET-related amputations were significantly higher in men versus women. The overall number of LEAs increased with age, particularly in patients ≥ 70 years. The increase in the total number of amputations was mainly due to a constant rise in minor amputations for both groups, regardless of gender. Conclusions: PAD- and/or AET-related LEAs in Romania increased from 2015 to 2019, with men having a greater incidence than women. Raising awareness and effective management strategies are needed to prevent LEAs.
RESUMO
OBJECTIVE: To provide an assessment of the cost burden of obesity across a spectrum of obesity-related comorbidities (ORCs) for four countries in South-Eastern Europe (SEE). METHODS: A micro-costing analysis from the public payer perspective was conducted to estimate direct healthcare costs associated with ten obesity-related comorbidities (ORCs) in Czech Republic, Greece, Hungary, and Romania. A survey was administered to obtain healthcare resource use and unit cost data. Cost estimates were validated by local steering committees which comprised at least one public sector clinician and a panel of independent industry experts. RESULTS: Chronic kidney disease and cardiovascular diseases were the costliest ORCs across all 4 countries, where annual cost burden per ORC exceeded 1,500 USD per patient per year. In general, costs were driven by the tertiary care resources allocated to address treatment-related adverse events, disease complications, and associated inpatient procedures. CONCLUSIONS: Our findings confirm that the high prevalence of obesity and its comorbidities result in substantial financial burden to all 4 SEE public payers. By quantifying the burden of obesity from a public healthcare perspective, our study aims to support policy efforts that promote health education and promotion in combating obesity in the region.

Social jetlag (SJL) and, more recently, eating jetlag have been linked with an increased risk of non-communicable diseases. Here we aim to investigate lifestyle factors (diet, eating behavior, smoking, perceived stress, time spent sedentary/day) and social determinants (education level, employment status, and place of residence) associated with SJL corrected for sleep duration (SJLsc) and eating jetlag. Self-declared data on age, gender, lifestyle, and eating behavior were collected online from March 2021 to February 2022 of 432 adults. Principal component analysis was used to extract three dietary patterns (Prudent, Western, and Risky). Prevalence of SJLsc was 35.2%, with no significant difference between men and women (p = 0.558). Adults with SJLsc had significantly larger eating jetlag (56.0 min vs 41.2 min, p = 0.001). Increasing SJLsc duration was associated with an increased adherence to a Risky dietary pattern (standardized ß coefficient = .165, p = 0.012); increasing eating jetlag duration was associated with an increased adherence to a Western dietary pattern (standardized ß coefficient = .127, p = 0.039) and a shorter sleep duration (standardized ßcoefficient = -0.147, p = 0.011). Among social determinants analyzed, only being a student or employed was associated with eating jetlag (standardized ß coefficient = 0.125, p = 0.044), while none displayed any relationship with SJLsc. Our survey provides evidence on a risky behavior among young persons with SJLsc and eating jetlag, characterized by a higher alcohol consumption, and a diet rich in processed meat and high-fat food, eating during nights, and shorter sleep duration with potential long-term negative health outcomes.

OBJECTIVES: This national representative survey sought to assess hypertension's prevalence, awareness, treatment and control in Romania. METHODS: A representative sample (by age, sex and residence) of 1477 Romanian adults (51.19â±â16.61âyears, range 18-80âyears, 59.9% women) was multimodally evaluated during two study visits. Hypertension was defined as SBP at least 140âmmHg and/or DBP at least 90âmmHg or previously diagnosed hypertension, regardless of BP. Awareness was defined by knowledge of previous hypertension diagnosis or of current use of antihypertensive treatment. Treatment was defined by antihypertensive medication taken at least 2 weeks prior to enrolment. Control was defined as SBP less than 140âmmHg and DBP less than 90âmmHg at both visits in treated hypertensive patients. RESULTS: Hypertension prevalence was 46% ( n â=â680) consisting of 81.02% ( n â=â551) known hypertensive patients and 18.98% ( n â=â129) newly diagnosed hypertensive patients. Awareness, treatment and control of hypertension were: 81% ( n â=â551), 83.8% ( n â=â462) and 39.2% ( n â=â181). CONCLUSION: Despite numerous pandemic-related obstacles in conducting a national survey, SEPHAR IV updates hypertension epidemiological data of a high-cardiovascular-risk Eastern-European population. This study confirms previous predictions of hypertension prevalence, treatment and control, which remain unfavourable because of unsatisfactory control of promoting factors.

With the onset of the COVID-19 outbreak, it was stipulated that patients with obstructive sleep apnea (OSA) may have a greater risk of morbidity and mortality and may even experience changes in their mental health. The aim of the current study is to evaluate how patients managed their disease (sleep apnea) during the COVID-19 pandemic, to determine if continuous positive airway pressure (CPAP) usage changed after the beginning of the pandemic, to compare the stress level with the baseline, and to observe if any modifications are related to their individual characteristics. The present studies highlight the level of anxiety, which was high among patients with OSA during the COVID-19 pandemic (p < 0.05), with its influence on weight control (62.5% of patients with high levels of stress gained weight) and sleep schedule (82.6% reported a change in sleep schedule). Patients with severe OSA and high levels of stress increased their CPAP usage (354.5 min/night vs. 399.5 min/night during the pandemic, p < 0.05). To conclude, in OSA patients, the presence of the pandemic led to a greater level of anxiety, changes in sleep schedule and weight gain because of job loss, isolation, and emotional changes, influencing mental health. A possible solution, telemedicine, could become a cornerstone in the management of these patients.

The present study aimed to investigate the association between apolipoprotein B (Apo B) and classical features associated with clinical or subclinical atherosclerosis. A total of 811 adult patients from the general Romanian population, included in the national SEPHAR registry on hypertension, were divided into two groups based on Apo B value (low versus high Apo B with a cut-off established at 130 mg/dL) and subsequently into four subgroups according to the cut-offs recommended by the 2021 ESC Guidelines on Cardiovascular Disease Prevention. In all patients, lipid profile, uric acid, full blood count and presence of significant carotid plaques were assessed. Apo B levels were positively correlated with proatherogenic lipids (total cholesterol, triglycerides and LDL-cholesterol, p < 0.0001) and negatively correlated with HDL cholesterol (all p < 0.05). In comparison with patients with low Apo B levels, those with elevated Apo B levels more frequently presented significant carotid plaques (17% vs. 19% vs. 28% vs. 46%, p < 0.0001). Univariate regression analysis identified a strong association between the level of uric acid and increased value of Apo B in the four subgroups (uric acid 4.8 +/- 1.3 vs. 5 +/- 1.6 vs. 5.1 +/- 1.5 vs. 5.8 +/- 1.6, r = 0.2, p < 0.0001). The results of this nationwide registry on hypertension in Romania indicate that high Apo B may be considered as a risk factor for CVD, promoting atherosclerosis and associated with increased expression of classical markers of clinical or subclinical CVD.

Essential hypertension (HTN) has a complex spectrum of pathophysiological determinants and current guidelines provide limited information on high-risk groups that should be targeted for its primary prevention. The objective of our research was to identify clusters of social and metabolic factors associated with prevalent HTN in men and women from a population-based survey in Romania. Of the 1477 participants in the main study, 798 with complete data were analyzed here. Using two-step cluster analysis, one high-risk cluster in women and two high and intermediate risk for prevalent HTN in men were identified. Older age, rural area, lower education, and higher burden of metabolic factors characterized clusters with higher risk, while intermediate risk in men was characterized by a more metabolically healthy phenotype in younger individuals. In logistic regression, men in Cluster 1 vs. those in Cluster 3 had an odds ratio (OR) of 9.6 (95%CI: 4.6; 20.0), p < 0.001 for prevalent HTN, while OR for Cluster 2 vs. Cluster 3 was 3.2 (95%CI: 1.4; 7.4), p = 0.005. In women, the OR for HTN was 10.2 (95%CI: 5.7; 18.5) if assigned to Cluster 2 vs. Cluster 1, p < 0.001. These results pointed out the subgroups and communities that the primary prevention of HTN should be prioritized in.

The objective of this scoping review was to summarize previous studies which examined the effect of day-to-day variability in sleep timing and social jetlag (SJL) on dietary intake. A systematic literature search was conducted in PubMed, Embase, and Clarivate Analytics Web of Science and we identified 22 records. No difference in caloric and macronutrient intake between SJL groups was observed in studies that enrolled healthy young adults. However, studies that enrolled participants with obesity and obesity-related chronic conditions reported a higher caloric intake and a higher intake of carbohydrates, total fat, saturated fats, and cholesterol in participants with SJL than in those without. Most studies reported a lower quality of diet, a delayed mealtime, and eating jetlag in participants with SJL vs. those without SJL. No correlation of day-to-day variability in sleep timing with average caloric intake was observed, but bed-time variability was negatively associated with diet quality. Methodological issues have been identified in sources assessed including study design, power calculation, population enrolled, and tools/metrics used for sleep timing variability assessment. Future well powered longitudinal studies, with clear protocols, standardized metrics, including all age groups from general population are needed to clarify the dietary intake consequences of variability in sleep timing.

The pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is one of the world's most disruptive health crises. The presence of diabetes plays an important role in the severity of the infection, and a rise in newly diagnosed diabetes cases has been identified. The aim of this retrospective study was to determine the incidence of new-onset diabetes (NOD) and predictive factors with their cut-off values for patients hospitalized with COVID-19. All patients (n = 219) hospitalized for COVID-19 during three consecutive months were included. NOD was diagnosed in 26.48% of patients. The severity of the infection, hospital admission values for fasting plasma glucose, lactate dehydrogenase (LDH), PaO2/FiO2 ratio, the peak values for leucocytes, neutrophils, C-reactive protein, triglycerides, and the need for care in the intensive care unit were predictors for the occurrence of NOD in univariate analysis, while only LDH level remained a significant predictor in the multivariable analysis. In conclusion, the results of the study showed a high incidence of NOD in patients hospitalized with COVID-19 and identified LDH levels at hospital admission as a significant predictor of NOD during SARS-CoV-2 infection. However, the persistence of NOD after the COVID-19 infection is not known, therefore, the results must be interpreted with caution.

The aim of this analysis was to assess the costs associated with the hospitalizations of persons with diabetes in a Romanian public hospital. We performed a retrospective "top-down" cost analysis of all adult patients discharged from a tertiary care hospital with an ICD-10 primary or secondary code of diabetes mellitus (type 1, type 2, or specific forms) between 1 January 2015 and 31 December 2018. All costs were adjusted with the annual inflation rates and converted to EUR. We included 16,868 patients with diabetes and 28,055 episodes of hospitalization. The total adjusted hospitalization cost in the analyzed period was EUR 26,418,126.8 and the adjusted median cost/episode of hospitalization was EUR 596.5. The mean length of a hospital stay/episode was 7.3 days. In the multivariate regression analysis, higher adjusted average costs/episodes of hospitalization and longer lengths of hospital stays were associated with increasing age, the presence of cardiovascular diseases, chronic kidney disease, and foot ulcerations. Moreover, a significant association between the average cost/episode of hospitalization and the length of hospital stay was observed (ß = 0.704, p < 0.001). This study shows the burden on Romanian public hospitals of inpatient diabetes care and the main drivers of the costs.

OBJECTIVES: To assess the effectiveness and safety of insulin glargine and lixisenatide (iGlarLixi) fixed-ratio combination on a cohort of Romanian adults with type 2 diabetes (T2D). DESIGN: Open-label, 24-week, prospective cohort study. SETTING: 65 secondary care diabetes centres in Romania. PARTICIPANTS: The study included 901 adults with T2D suboptimally controlled with previous oral antidiabetic drugs (OADs)±basal insulin (BI) who initiated treatment with iGlarLixi upon the decision of the investigator. Major exclusion criteria were iGlarLixi contraindications and refusal to participate. 876 subjects received at least one dose of iGlarLixi (intention-to-treat/safety population). PRIMARY AND SECONDARY OUTCOME MEASURES: The primary endpoint was change in glycated haemoglobin (HbA1c) from baseline to week 24 in the modified intention-to-treat population (study participants with HbA1c available at baseline and week 24). Secondary efficacy outcomes were percentage of participants reaching HbA1c targets and change in fasting plasma glucose (FPG). RESULTS: Mean baseline HbA1c was 9.2% (SD 1.4) and FPG was 10.8 mmol/L (2.9). Mean HbA1c change was -1.3% (95% CI: -1.4% to -1.2%, p<0.0001) at week 24. HbA1c levels ≤6.5%, <7% and<7.5% at week 24 were achieved by 72 (8.9%), 183 (22.6%) and 342 (42.3%) participants, respectively. Mean FPG change was -3.1 mmol/L (95% CI: -3.3 to -2.8, p<0.001) at week 24. Mean body weight change was -1.6 kg (95% CI: -1.9 to -1.3, p<0.001) at 24 weeks. Mean iGlarLixi dose increased from 19.5 U (SD 7.7) and 30.1 U (10.0) to 30.2 U (8.9) (ratio 2/1 pen) and 45.0 U (11.6) (ratio 3/1 pen). Adverse events (AEs) were reported by 43 (4.9%) participants (18 (2.1%) gastrointestinal) with 4 (0.5%) reporting serious AEs. 13 (1.5%) participants reported at least one event of symptomatic hypoglycaemia, with one episode of severe hypoglycaemia reported. CONCLUSIONS: In a real-world setting, 24-week treatment with iGlarLixi provided a significant reduction of HbA1c with body weight loss and low hypoglycaemia risk in T2D suboptimally controlled with OADs±BI treatment.

E-selectin is an endothelial cell adhesion molecule involved in vascular inflammation. Elevated E-selectin has been reported in patients with high blood pressure and diabetes. Given the increasing clinical relevance of parameters derived from ambulatory blood pressure monitoring, further investigation of their relationships with E-selectin is of interest. In this study, we aimed to investigate the association between serum E-selectin, office blood pressure and 24 h ambulatory blood pressure parameters in patients with type 2 diabetes. Blood pressure variability was assessed by computing the standard deviation of mean systolic and diastolic blood pressure separately for daytime and nighttime during 24 h ambulatory blood pressure monitoring in a cohort of patients with type 2 diabetes (n = 132). Additionally, were assessed nighttime systolic dipping and pulse pressure separately for daytime, nighttime, and 24 h. Serum E-selectin was measured using the enzyme-linked immunosorbent assay technique. We found that E-selectin was consistently associated with 24 h diastolic blood pressure variability (r = 0.238; p = 0.019) and daytime diastolic blood pressure variability (r = 0.258; p = 0.012), after adjustment for confounding factors. No association of E-selectin with office blood pressure and other 24 h ambulatory blood pressure parameters was observed. In conclusion, endothelial activation indicated by elevated serum E-selectin is associated with increased ambulatory diastolic blood pressure variability in patients with type 2 diabetes.
RESUMO
Diabetes mellitus is considered to be a global epidemic. The combination of genetic susceptibility and an unhealthy lifestyle is considered to be the main trigger of this metabolic disorder. Recently, there has been increased interest in the roles of gut microbiota as a new potential contributor to this epidemic. Research, in recent years, has contributed to an in-depth characterization of the human microbiome and its associations with various diseases, including metabolic diseases and diabetes mellitus. It is known that diet can change the composition of gut microbiota, but it is unclear how this, in turn, may influence metabolism. The main objective of this review is to evaluate the pathogenetic association between microbiota and diabetes and to explore any new therapeutic agents, including nutraceuticals that may modulate the microbiota. We also look at several mechanisms involved in this process. There is a clear, bidirectional relationship between microbiota and diabetes. Current treatments for diabetes influence microbiota in various ways, some beneficial, but others with still unclear effects. Microbiota-aimed treatments have seen no real-world significant effects on the progression of diabetes and its complications, with more studies needed in order to find a really beneficial agent.
RESUMO
This research aimed to explore the relation of social jetlag (SJL) with perceived appetite, and hormones involved in hunger regulation in healthy subjects in free-living conditions (study registration number: ACTRN12618001182280). Eighty normally diurnally active men and women were enrolled in 4 study groups according to the presence of SJL and sleep deprivation (2 groups with SJL with or without sleep deprivations and 2 groups without SJL with or without sleep deprivation) matched 1:1:1:1 for age, gender, and body mass index. Appetite was assessed in fasting state, by measuring acylated ghrelin level and using 100 mm visual analog scales. Persons with SJL had a higher perceived appetite for pork, poultry, fish, eggs, milk, and dairy products and higher acylated ghrelin levels than those without SJL. When considering the presence of sleep deprivation, subjects with SJL, with and without sleep deprivation, reported a higher perceived appetite than group with sleep deprivation alone. They also reported later meal times for lunch and dinner, had more frequently a snack before sleep and reported eating more frequently while watching TV or playing on computer, suggesting poorer eating habits in these subjects. In conclusion, independent of sleep duration, SJL is associated with an increased appetite for caloric dense food, suggesting an increased incentive value of food in these subjects and an anticipated pleasure of ingesting these foods.

Oxidative stress plays a key role in the development of chronic diabetes-related complications. Previous metabolomic studies showed a positive association of diabetes and insulin resistance with branched-chain amino acids (AAs) and aromatic AAs. The purpose of this research is to identify distinct metabolic changes associated with increased oxidative stress, as assessed by nitrotyrosine levels, in type 2 diabetes (T2DM). Serum samples of 80 patients with insulin-treated T2DM are analyzed by AA-targeted metabolomics using ultrahigh-performance liquid chromatography/mass spectrometry. Patients are divided into two groups based on their nitrotyrosine levels: the highest level of oxidative stress (Q4 nitrotyrosine) and lower levels (Q1-Q3 nitrotyrosine). The identification of biomarkers is performed in MetaboAnalyst version 5.0 using a t-test corrected for false discovery rate, unsupervised principal component analysis and supervised partial least-squares discriminant analysis (PLS-DA). Four AAs have significantly different levels between the groups for highest and lower oxidative stress. Cysteine, phenylalanine and tyrosine are substantially increased while citrulline is decreased (p-value <0.05 and variable importance in the projection [VIP] >1). Corresponding pathways that might be disrupted in patients with high oxidative stress are phenylalanine, tyrosine and tryptophan biosynthesis, arginine biosynthesis, phenylalanine metabolism, cysteine and methionine metabolism and tyrosine metabolism.
RESUMO
High normal blood pressure (HNBP) is associated with an increased risk of incident high blood pressure (HBP) and of cardiovascular diseases (CVD). To estimate the prevalence of HNBP and related cardiovascular risk factors, a representative sample of 1970 Romanian adults was enrolled in SEPHAR III survey (Study for the Evaluation of Prevalence of Hypertension and Cardiovascular Risk in Romania). All were evaluated for blood pressure values and by a 71-item questionnaire, anthropometric measurements, together with extensive evaluation for target organ damage, blood, and urine sample collection. Prevalence of HNBP was 11% [45.1% had HBP, 43.9% normal BP (NBP)]. HNBP individuals were older (51.14 ± 17.13 years) than subjects with NBP (40.5 ± 15.96 years) but younger than those with HBP (55.79 ± 15.68 years), p < 0.0001 (95% CI 18-85, respectively 18-91). Values of weight, waist circumference, body mass index, total and LDL cholesterol, triglycerides, fasting blood glucose, glycosylated hemoglobin (HbA1c), uric acid, serum creatinine, glomerular filtration rate estimate by CKD-EPI equation, urinary albumin to creatinine ratio, intimae-media thickness, arterial stiffness measurements and diastolic dysfunction, indexed left ventricular mass, interventricular septum and posterior left ventricle wall thickness, left atrial volume, and LA dilatation were significantly higher in HNBP subjects than in NBP. Our study showed that individuals with HNBP represent ~11% and most of them had an elevated total cardiovascular risk. It is essential to educate the public and health care providers to be aware of these individuals and of steps that should be taken to treat modifiable cardiovascular risk factors.

OBJECTIVE: The aim of this research was to assess the effect of social jetlag (SJL) and its interaction with partial sleep deprivation on resting-state brain activity using the fractional amplitude of low-frequency fluctuation (fALFF) during free-living conditions. METHODS: A total of 28 normal weight healthy subjects were enrolled in four study groups (with SJL [with sleep deprivation and without sleep deprivation] and without SJL [with sleep deprivation and without sleep deprivation]), matched 1:1:1:1 for age, gender, and body mass index (BMI). Resting-state functional magnetic resonance imaging (fMRI) scans were collected with SIEMENS 3T scanner while subjects were in a fasting state. RESULTS: Participants with SJL had significantly higher fALFF values in right lingual gyrus and right putamen and significantly lower fALFF values in left and right inferior parietal lobe in comparison with participants without SJL and without sleep deprivation. Subjects with sleep deprivation had significantly higher fALFF in the thalamus and left superior frontal gyrus. In those with both SJL and sleep deprivation, we observed higher fALFF values in right Brodmann Area (BA)18 and lower values in left and right parietal inferior lobe. Subjects with SJL alone had significantly lower fALFF values in left frontal mid gyrus (BA6) than those with sleep deprivation alone. CONCLUSIONS: SJL was associated with altered resting-state brain activity in regions that have been shown to be involved in hedonic feeding. The effect of SJL was independent of effects induced by short sleep duration. These alterations might represent the substrate for the increased risk of obesity observed in those with SJL.
