Mindful eating (ME) has been linked to improvement in binge eating disorder, but this approach in obesity management has shown conflicting results. Our aim was to assess the effect of ME associated with moderate energy restriction (MER) on weight loss in women with obesity. Metabolic parameters, dietary assessment, eating behaviour, depression, anxiety and stress were also evaluated. A total of 138 women with obesity were randomly assigned to three intervention groups: ME associated with MER (ME + MER), MER and ME, and they were followed up monthly for 6 months. ME + MER joined seven monthly mindfulness-based intervention group sessions each lasting 90 min and received an individualised food plan with MER (deficit of 2092 kJ/d - 500 kcal/d). MER received an individualised food plan with MER (deficit of 2092 kJ/d - 500 kcal/d), and ME joined seven monthly mindfulness-based intervention group sessions each lasting 90 min. Seventy patients completed the intervention. Weight loss was significant, but no statistically significant difference was found between the groups. There was a greater reduction in uncontrolled eating in the ME group than in the MER group and a greater reduction in emotional eating in the ME group than in both the MER and the ME + MER groups. No statistically significant differences were found in the other variables evaluated between groups. The association between ME with energy restriction did not promote greater weight loss than ME or MER.
Loneliness, a negative emotion stemming from the perception of unmet social needs, is a major public health concern. Current interventions often target social domains but produce small effects and are not as effective as established emotion regulation (ER)-based interventions for general psychological distress (i.e., depression/anxiety). Given that loneliness and distress are types of negative affect, we aimed to compare them within an ER framework by examining the amount of variance ER strategies accounted for in loneliness versus distress, and comparing the ER strategy profiles characterising them. Participants (N = 582, Mage = 22.31, 77.66% female) completed self-report measures of loneliness, distress, and use of 12 cognitive (e.g., cognitive reappraisal) or behavioural (e.g., expressive suppression) ER strategies. Regression analyses revealed that ER explained comparable variance in these constructs. Latent profile analysis identified seven profiles differing in ER patterns, with no distinct loneliness or distress profile identified. Rather, similar patterns of ER characterised these two constructs, involving the greater use of generally maladaptive strategies and the lesser use of generally adaptive strategies. However, loneliness was additionally characterised by less use of strategies involving social connection/expression. Overall, our study supports the utility of ER for understanding loneliness. Established ER-based frameworks/interventions for distress may have transdiagnostic utility in targeting loneliness.
Despite the multitude of clinical manifestations of post-acute sequelae of SARS-CoV-2 infection (PASC), studies applying statistical methods to directly investigate patterns of symptom co-occurrence and their biological correlates are scarce.
Methods
We assessed 30 symptoms pertaining to different organ systems in 749 adults (age = 55 ± 14 years; 47% female) during in-person visits conducted at 6–11 months after hospitalization due to coronavirus disease 2019 (COVID-19), including six psychiatric and cognitive manifestations. Symptom co-occurrence was initially investigated using exploratory factor analysis (EFA), and latent variable modeling was then conducted using Item Response Theory (IRT). We investigated associations of latent variable severity with objective indices of persistent physical disability, pulmonary and kidney dysfunction, and C-reactive protein and D-dimer blood levels, measured at the same follow-up assessment.
Results
The EFA extracted one factor, explaining 64.8% of variance; loadings were positive for all symptoms, and above 0.35 for 16 of them. The latent trait generated using IRT placed fatigue, psychiatric, and cognitive manifestations as the most discriminative symptoms (coefficients > 1.5, p < 0.001). Latent trait severity was associated with decreased body weight and poorer physical performance (coefficients > 0.240; p ⩽ 0.003), and elevated blood levels of C-reactive protein (coefficient = 0.378; 95% CI 0.215–0.541; p < 0.001) and D-dimer (coefficient = 0.412; 95% CI 0.123–0.702; p = 0.005). Results were similar after excluding subjects with pro-inflammatory comorbidities.
Conclusions
Different symptoms that persist for several months after moderate or severe COVID-19 may unite within one latent trait of PASC. This trait is dominated by fatigue and psychiatric symptoms, and is associated with objective signs of physical disability and persistent systemic inflammation.
Non-suicidal self-injury (NSSI) is a clinical condition defined as intentional, self-inflicted act causing pain or superficial damage without suicidal intents (12-35% of the adolescent community). Several findings show a high correlation between NSSI and impairments in the impulsivity control.
Objectives
The goal of our study is to evaluate the role of impulsivity in NSSI adolescents, relatively to the inhibitory control, in order to investigate if it can represent a neurocognitive risk factor underlying maladaptive behaviours and which psychopathological dimensions can be associated with this neurobiological process.
Methods
30 NNSI inpatients (age range: 12 to 18 years), drug-free, were compared with an age-matched control group, using two behavioural paradigms for the study of inhibitory control: the Stop Signal task and the emotive go/Nogo. Psychopathological traits were evaluated by self-report questionnaires for impulsivity dimensions, suicidality and self-injurious acts. Statistical analyses were performed with SPSS program (p =0.05).
Results
NSSI patients did not present impairments in the global inhibitory control but they had longer movement times in both paradigms and faster reaction times in the Go/no-go behavioural paradigm. Therefore, NSSI patients tended to be impulsive at an early stage of movement (rapid TR) and have to slow down in a second phase (TM slow) in order to have time to rework the cognitive processes underlying movement.
Conclusions
The impulsivity dimension is a complex construct that involves multiple interconnected factors. The study of neuro-cognitive and psychopathological aspects and how they are interconnected is necessary to draw new perspectives on the etiopathogenesis of NNSI.
Anorexia nervosa (AN) and bulimia nervosa (BN) are complex psychiatric conditions, in which both psychological and metabolic factors have been implicated. Critically, the experience of stress can precipitate loss-of-control eating in both conditions, suggesting an interplay between mental state and metabolic signaling. However, associations between psychological states, symptoms and metabolic processes in AN and BN have not been examined.
Methods
Eighty-five women (n = 22 AN binge/purge subtype, n = 33 BN, n = 30 controls) underwent remote salivary cortisol sampling and a 2-day, inpatient study session to examine the effect of stress on cortisol, gut hormones [acyl-ghrelin, peptide tyrosine tyrosine (PYY) and glucagon-like peptide-1] and food consumption. Participants were randomized to either an acute stress induction or control task on each day, and plasma hormones were serially measured before a naturalistic, ad libitum meal.
Results
Cortisol-awakening response was augmented in AN but not in BN relative to controls, with body mass index explaining the most variance in post-awakening cortisol (36%). Acute stress increased acyl-ghrelin and PYY in AN compared to controls; however, stress did not alter gut hormone profiles in BN. Instead, a group-by-stress interaction showed nominally reduced cortisol reactivity in BN, but not in AN, compared to controls. Ad libitum consumption was lower in both patient groups and unaffected by stress.
Conclusions
Findings extend previous reports of metabolic dysfunction in binge-eating disorders, identifying unique associations across disorders and under stress. Moreover, we observed disrupted homeostatic signaling in AN following psychological stress, which may explain, in part, the maintenance of dysregulated eating in this serious illness.
The functional neuroimaging studies of emotion processing in schizophrenia have revealed variable results attributed partly to differential symptomatology and sex of tested patients. The aim of the present study was to investigate the relationship between cerebral activations during exposure to emotional material and schizophrenia symptoms in men versus women.
Method
Fifteen men and 10 women with schizophrenia, equivalent in terms of age, medication and experienced symptomatology, underwent functional MRI during viewing sad and neutral film excerpts. Data were analyzed using Statistical Parametric Mapping Software (SPM2).
Results
Across all the patients there was a significant inverse relationship between negative symptoms and activations in the right prefrontal cortex during processing of sad versus neutral stimuli. In men, activations during sad versus neutral stimuli in the prefrontal, temporal and anterior cingulate cortex, as well as the caudate and cerebellum, were positively correlated with negative symptoms. In women, there were inverse correlations between positive symptoms and activations in the hippocampus, parietal and occipital cortex during the same condition.
Conclusion
Present results confirmed association of prefrontal hypofunction with negative symptoms in schizophrenia. More interestingly, the results revealed a diametrically different pattern of symptom-correlated brain activity in men and women with schizophrenia, suggesting that the processing of sadness is mediated via neurophysiological mechanism related to negative symptoms in men and the mechanism related to positive symptoms in women.
The recent research (Barkley, 1997) showed a significant relation between ADHD and difficulties in emotional regulation among primary school children. During adolescence these problems can lead to risk behaviors, such as substance abuse till increasing aggressive behaviors and even a conduct disorder (Ghanizadeh et al., 2008). This experience provides to realize a intervention about emotional and behavior regulation on two groups of primary school children between 8 and 11 years old (N1=4; N2=5) with a ADHD diagnosis.
Our intervention encloses an initial assessment about the children's neuropsychological performance, a course that deals with the emotional and behavioral regulation, based on cognitive-behavioral techniques, and a final assessment to evaluate the outcomes.
The effectiveness of this kind of intervention is shown by lots of researches (Kendall, 1992); so we expect that it will increase cooperation among the groups, improve the ability of emotional regulation, in particular the system frustration/aggression, and allow a better regulation of impulsive behaviors.
Up to today, there are experimental evidences pointing out the usefulness of cognitive-behavioral interventions for the treatment of children with Attention Deficit / Hyperactivity Disorder (ADHD), including the Parent Training, classified as’empirically validated treatment’ and mainly suitable to build specific parenting skills (Pelham, Wheeler e Chronis, 1998; SINPIA, 2006).
Objectives:
This study examines a process of Parent Training carried out with a group of parents of children with ADHD.
Aims:
Improving the parenting knowledge and skills in the strategies of management of children's problematic behaviors; encouraging the expression of emotions and managing parental stress.
Methods:
The training takes place in 12 meetings, the group is formed by 4 couples of parents of children diagnosed with ADHD.
Evaluation of the effectiveness of the treatment: subjective criterion, concerning the degree of satisfaction expressed by parents in using the educational intervention techniques, learned and experienced in the group work, and objective criterion through the use of standardized pre-and post-treatment assessment tools: Parent Stress Index (PSI -RR Abidin, 2008) and Alabama Parent Questionnaire (APQ - Frick, 1991).
Results:
Acquisition of a specific knowledge of the Attention Deficit Disorder / Hyperactivity, of the strategies to manage the child's behavior, development of a parental attitude oriented toward problem-solving, becoming thus positive models of behavior, in order to promote family relationships.
Conclusions:
This intervention adds to the management of the problems related to ADHD, the support and the management of the emotional aspects related to parental competence.
Anxiety disorders and Cardiovascular (CV) diseases, among the most common disorders in Western World, are often comorbid. A chronic systemic inflammatory state might be a shared underlining pathophysiological mechanism.
Aims
To investigate the association between anxiety symptoms, CV risks factors and inflammatory markers in an outpatient sample.
Methods
Cross-sectional study. Inclusion criteria: outpatients aged ≥40 years, attending colonoscopy after positive faecal occult blood test, negative medical history for cancer. Collected data: blood pressure, glycaemia, lipid profile, waist circumference, BMI, PCR (C Reactive Protein), LPS (bacterial Lipopolysaccharide). Psychometric tests: HADS, TCI, IMSA, SF36. Statistical analysis performed with STATA13.
Results
Fifty four patients enrolled (27 males, 27 females). Sixteen patients (30.19%) were positive for anxiety symptoms. Thirty-three patients (61.11%) had hypertension, 14 (25.93%) hyperglycaemia and 64.81% were overweight, with frank obesity (BMI≥ 30) in 11 subjects (20.37%). Anxiety symptoms were associated with low hematic HDL values (OR = 0.01; P = 0.01) and high concentration of triglycerides (OR = 0.023; P = 0.02) at the multiple regression model. At the univariate logistic analysis, anxiety was associated with LPS (OR = 1.06; P = 0.04).
Conclusions
Further evidence over the epidemiological link between common mental disorders and CV diseases was collected, with possible hints on pathophysiology and causative mechanisms related to inflammation. The importance of screening for anxiety and depression in medical populations is confirmed. Suggestions on future availability of screening tools based on inflammatory-related indicators should be the focus of future research.

Polydrug abuse seems to be especially popular in Ibiza, an important market for new psychoactive substances (NPS). The misuse of psychoactive substances can lead to serious psychiatric symptoms.
Aims
To evaluate symptoms induced by NPSs and other club drugs, correlating with the main classes of drugs.
Methods
Ninety subjects (M/F 59/31) admitted in the Psychiatric Unit of Can Misses Hospital (Ibiza) referring a recent intake of substances were enrolled. The following scales were administered: TLFB (Timeline follow-back); Positive and Negative Symptoms Scale (PANSS); Symptom checklist-90 (SCL-90) ; Young Mania Rating Scale (YMRS) ; Hamilton Depression Scale (HAM-D); Hamilton Anxiety Scale (HAM-A); Modified Overt Aggression Scale (MOAS); Columbia Suicide Severity Rating Scale (C-SSRS).
Results
Polydrug abuse was reported by 67.4% of the sample; the sample was grouped by the main preferred substance in THC-, stimulants-, and depressors-users. The majority of patients reported a previous psychiatric history. Positive symptoms resulted to be higher among THC-users (P < .05). Anxiety evaluated by SCL-90 was prevalent in the group of Depressors-users (P < .05). The scores of MOAS and SCL-90 subscale for hostility/aggression resulted to be significantly (P < .01) greater in the THC-users group.
Conclusions
Some specific psychiatric symptoms are characteristic of some classes of substances and may help to identify them when a urine sample is not available. The possibility to develop psychiatric symptoms after a recent drug use is more common in two situations: (1) patients with a previous psychiatric history; (2) subjects with a history of very strong substance use.

Pro-inflammatory states of the large bowel have a multifactorial aetiology, including metabolism, atherogenesis, and psychological determinants. Inflammation plays a role in depressive and anxiety disorders, is tightly associated with early pro-atherogenetic alterations and metabolic dysregulation, and is also a key factor for the development of colorectal cancer.
Aim
To investigate the association between pro-atherogenetic factors, metabolic status, psychological assessment and presence of colorectal adenomas.
Methods
Case-control study, approved by the local Ethic Committee. Patients aged 40 or more and undergoing colonoscopy for positive faecal blood test and/or abdominal symptoms, with a negative history for neoplasia or inflammatory bowel diseases, were enrolled. For each patient the following data were collected: waist and hip circumferences, BMI, arterial pressure, fasten serum glycemia, current medications. Beside colonoscopy, carotid intima-media thickness (IMT) was assessed by means of echographic evaluation. Psychometric assessment included HADS, TCI, IMSA, SF-36. Statistics performed with SigmaPlot v.12 Platform.
Results
Preliminary results are available for 18 patients (male/female 8/10) Mean age 62.6 ± 8.4. Ten patients had at least one adenoma, 8 patients had no lesions. The following differences were noticeable: HADS-depression (mean ± SD) adenoma vs. no-adenoma: 4.9 ± 3.2 vs. 1.7 ± 1.8 (P < .01); IMT median value adenoma vs. no-adenoma: 793 vs. 638 micrometers (P = .04); Body weight (mean ± SD) adenoma vs. no-adenoma: 66.4 ± 8.7 kg vs. 80.9 ± 15.3 kg (P = .03); waist circumference (mean ± SD) adenoma vs. no-adenoma: 105.2 ± 13.4 cm vs. 89.5 ± 4.7 cm (P < .01).
Conclusions
Preliminary data from PNEI-MO Research Group support the relation between systemic inflammation, psychological status and development of precancerous colorectal cancer lesions. Depression seems associated with the presence of colorectal adenomas.

The purpose of this study was to investigate cognitive functioning in Borderline Personality Disorder subjects, with particular reference to the Working Memory functioning. The Working Memory seems to be relate to core features of the disturb. The final aim was to better understand the disorder and to implement a cognitive training to improve the deficits.
Methods
A literature search was conducted in April 2015. Pubmed and Scopus databases were used to find studies to include in the systematic review. The keywords used for the literature search were: “borderline personality disorder”, “borderline personality”, “working memory”, “executive functioning”. In each search, the keywords were used together with the logical operator “and”.
Summary
Three studies were included in this systematic review (Table 1). In each study, the working memory was investigated using N-back test. In two of those studies significantly differences were found between patients and healthy group in N-back task. In the third study, which used more tests to investigate working memory domain, no differences were found between the two groups.
Conclusions
Borderline personality disorder patients performed significantly worse on the N-back test compared to healthy controls and the impairment increased with increasing working memory load. In the third study the working memory domain was investigated using four different tests and single scores were not included therefore it was impossible to compare N-back data.

Growing evidence has been collected over the complex, intertwined pathophysiological connection among subclinical cardiovascular (CV) disease, i.e. atherosclerosis, systemic low pro-inflammatory states and psychiatric disorders/symptomatology (anxiety, depression), with controversial results.
Aim
Aim of this study was to investigate the possible link between subclinical CV risk factors (atherosclerosis), depressive symptoms, and inflammation.
Methods
Cross-sectional study. Inclusion criteria: outpatients aged ≥40 years, attending colonoscopy after positive faecal occult blood test, negative medical history for cancer. Collected data: blood pressure, glycaemia, lipid profile, waist circumference, BMI, PCR (C reactive protein), LPS (bacterial lipopolysaccharide), ultrasound carotid intima-media thickness (c-IMT). Psychometric tests: HADS, TCI, IMSA, SF36. Statistical analysis performed with STATA13.
Results
The 54 patients enrolled were equally distributed by gender. CV risk factors were common in the study population, with 33 patients (61.11%) with hypertension, 14 (25.93%) with hyperglycaemia, 20 (37.4%) with hypertriglyceridemia, 19 (35.19%) with low HDL and 64.81% with overweight. High levels of PCR were found in 24 subjects (44.44%). Right c-IMT was increased in 26.41% of the sample, and 11.32% had an atheromatous plaque. Left c-IMT was increased in 24.53% of patients, with a plaque in 7.55% of them. Clinically relevant depressive symptoms were found in the 18.87% of the sample and were statistically significantly associated with PCR (OR = 28.63; P = 0.01).
Conclusions
Evidence contributing to the so-called “inflammation theory” of depression and supporting the association between mood and CV disorders was here collected, supporting the need for a multidisciplinary approach to the diagnosis and treatment of such conditions, assuming a clinically-translated PNEI (psycho-neuro-endocrino-immunological) perspective.

Inflammatory state of the large bowel is a key factor for the development of colorectal cancer (CRC). It has multifactorial aetiology, including psychological determinants. Physical activity may have a protective function against CRC via anti-inflammatory properties; on the contrary, personality traits correlate with an unhealthy and dangerous lifestyle.
Objective
To measure the association between personality traits, lifestyle and colonoscopy outcome.
Methods
Cross sectional study. Patients undergoing colonoscopy aged 40 or more, with a negative history for cancer or inflammatory bowel disease, were enrolled. Data collected: colonoscopy outcome, smoke, alcohol, physical activity, presence/absence of Metabolic Syndrome, personality traits assessed by the Temperament & Character Inventory (TCI).
Results
In a sample of 53 subjects (females = 24, 45.3%), the mean age was 60.66 ± 9.08. At least one adenoma was found to 23 patients (43.3%). Twenty patients were smokers (37.74%), 36 (67.92%) drank alcohol at least weekly; approximately 60% reported regular physical activity. At the multivariate regression, the outcome was associated to: TCI Self Transcendence domain (ST) (OR = 1.36, P = 0.04) and physical activity (OR = 0.14, P = 0.03).
Conclusion
People with ST's characteristic personality traits and sedentary life style are more likely to have precancerous colorectal lesions. This confirms the protective role of physical activity, and suggests to further explore the role of personality in cancerogenesis.

Brightest cluster galaxies (BCGs) residing in cool-core clusters are known to be the stage of intricate baryon cycle phenomena (e.g. gas inflows, AGN outflows, star formation feedback). The scenarios describing the observed properties of these galaxies are still controversial, suffering from limitations due to the spatial resolving power of the instruments, specifically for galaxies beyond the Local Universe. However, the dramatic improvements introduced by the integral-field unit instruments (e.g. MUSE) could shed light on the physical processes driving the evolution of these galaxies. We present an extensive analysis of the stellar and gas properties (i.e. kinematics, stellar mass, star formation rate) of the radio-loud BCG sitting at the centre of the X-ray luminous cool-core cluster Abell 2667 (z = 0.23), based on MUSE data. Our results indicate that the BCG is a massive elliptical, hosting an AGN that is possibly undergoing accretion of cold star-forming clouds of ICM or galactic cannibalism.
Experimental studies have reported on the anti-inflammatory properties of polyphenols. However, results from epidemiological investigations have been inconsistent and especially studies using biomarkers for assessment of polyphenol intake have been scant. We aimed to characterise the association between plasma concentrations of thirty-five polyphenol compounds and low-grade systemic inflammation state as measured by high-sensitivity C-reactive protein (hsCRP). A cross-sectional data analysis was performed based on 315 participants in the European Prospective Investigation into Cancer and Nutrition cohort with available measurements of plasma polyphenols and hsCRP. In logistic regression analysis, the OR and 95 % CI of elevated serum hsCRP (>3 mg/l) were calculated within quartiles and per standard deviation higher level of plasma polyphenol concentrations. In a multivariable-adjusted model, the sum of plasma concentrations of all polyphenols measured (per standard deviation) was associated with 29 (95 % CI 50, 1) % lower odds of elevated hsCRP. In the class of flavonoids, daidzein was inversely associated with elevated hsCRP (OR 0·66, 95 % CI 0·46, 0·96). Among phenolic acids, statistically significant associations were observed for 3,5-dihydroxyphenylpropionic acid (OR 0·58, 95 % CI 0·39, 0·86), 3,4-dihydroxyphenylpropionic acid (OR 0·63, 95 % CI 0·46, 0·87), ferulic acid (OR 0·65, 95 % CI 0·44, 0·96) and caffeic acid (OR 0·69, 95 % CI 0·51, 0·93). The odds of elevated hsCRP were significantly reduced for hydroxytyrosol (OR 0·67, 95 % CI 0·48, 0·93). The present study showed that polyphenol biomarkers are associated with lower odds of elevated hsCRP. Whether diet rich in bioactive polyphenol compounds could be an effective strategy to prevent or modulate deleterious health effects of inflammation should be addressed by further well-powered longitudinal studies.
To examine timing of eating across ten European countries.
Design
Cross-sectional analysis of the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study using standardized 24 h diet recalls collected during 1995–2000. Eleven predefined food consumption occasions were assessed during the recall interview. We present time of consumption of meals and snacks as well as the later:earlier energy intake ratio, with earlier and later intakes defined as 06.00–14.00 and 15.00–24.00 hours, respectively. Type III tests were used to examine associations of sociodemographic, lifestyle and health variables with timing of energy intake.
Setting
Ten Western European countries.
Subjects
In total, 22 985 women and 13 035 men aged 35–74 years (n 36 020).
Results
A south–north gradient was observed for timing of eating, with later consumption of meals and snacks in Mediterranean countries compared with Central and Northern European countries. However, the energy load was reversed, with the later:earlier energy intake ratio ranging from 0·68 (France) to 1·39 (Norway) among women, and from 0·71 (Greece) to 1·35 (the Netherlands) among men. Among women, country, age, education, marital status, smoking, day of recall and season were all independently associated with timing of energy intake (all P<0·05). Among men, the corresponding variables were country, age, education, smoking, physical activity, BMI and day of recall (all P<0·05).
Conclusions
We found pronounced differences in timing of eating across Europe, with later meal timetables but greater energy load earlier during the day in Mediterranean countries compared with Central and Northern European countries.
Distinguishing temporal patterns of depressive symptoms during pregnancy and after childbirth has important clinical implications for diagnosis, treatment, and maternal and child outcomes. The primary aim of the present study was to distinguish patterns of chronically elevated levels of depressive symptoms v. trajectories that are either elevated during pregnancy but then remit after childbirth, v. patterns that increase after childbirth.
Methods
The report uses latent growth mixture modeling in a large, population-based cohort (N = 12 121) to investigate temporal patterns of depressive symptoms. We examined theoretically relevant sociodemographic factors, exposure to adversity, and offspring gender as predictors.
Results
Four distinct trajectories emerged, including resilient (74.3%), improving (9.2%), emergent (4.0%), and chronic (11.5%). Lower maternal and paternal education distinguished chronic from resilient depressive trajectories, whereas higher maternal and partner education, and female offspring gender, distinguished the emergent trajectory from the chronic trajectory. Younger maternal age distinguished the improving group from the resilient group. Exposure to medical, interpersonal, financial, and housing adversity predicted membership in the chronic, emergent, and improving trajectories compared with the resilient trajectory. Finally, exposure to medical, interpersonal, and financial adversity was associated with the chronic v. improving group, and inversely related to the emergent class relative to the improving group.
Conclusions
There are distinct temporal patterns of depressive symptoms during pregnancy, after childbirth, and beyond. Most women show stable low levels of depressive symptoms, while emergent and chronic depression patterns are separable with distinct correlates, most notably maternal age, education levels, adversity exposure, and child gender.
Obesity and osteoporosis may have their origins in early postnatal life. This study was designed to evaluate whether flaxseed flour use during lactation period bears effect on body adiposity and skeletal structure of male rat pups at weaning. At birth, male Wistar rats were randomly assigned to control and experimental (FF) groups, whose dams were treated with control or flaxseed flour diet, respectively, during lactation. At 21 days of age, pups were weaned to assess body mass, length and composition by dual-energy X-ray absorptiometry. The animals were then sacrificed to carry out analysis of serum profile, intra-abdominal adipocyte morphology and femur characteristics. Differences were considered significant when P<0.05. The FF group displayed the following characteristics (P<0.05): higher body mass, length, bone mineral content, bone area and concentrations of osteoprotegerin, osteocalcin and high-density lipoprotein cholesterol; higher levels of stearic, α-linolenic, eicosapentaenoic and docosapentaenoic acids and lower levels of arachidonic acid and cholesterol; smaller adipocyte area; and higher mass, epiphysis distance, diaphysis width, maximal load, break load, resilience and stiffness of femur. Flaxseed flour intake during lactation period promoted adipocyte hypertrophy down-regulation and contributed to pup bone quality at weaning.
