<p dir="ltr">Frontloading is an alcohol drinking pattern where intake is skewed toward the onset of access. The goal of the current study was to identify brain regions involved in frontloading using whole brain imaging. 63 C57Bl/6J (32 female and 31 male) mice underwent 8 days of binge drinking using drinking-in-the-dark (DID). Three hours into the dark cycle, mice received 20% (v/v) alcohol or water for two hours on days 1-7. Intake was measured in 1-minute bins using volumetric sippers, which facilitated analyses of drinking patterns. Mice were perfused 80 minutes into the day 8 DID session and brains were extracted and processed for iDISCO clearing and c-fos immunohistochemistry. For brain network analyses, day 8 drinking patterns were used to characterize mice as frontloaders or non-frontloaders using a change-point analysis described in our recent ACER publication (Ardinger et al., 2022). Groups were female frontloaders (n = 20), female non-frontloaders (n = 2), male frontloaders (n = 13) and male non-frontloaders (n = 8). There were no differences in total alcohol intake as a function of frontloading status. Water drinkers had an n of 10 for each sex. As only two female mice were characterized as non-frontloaders, it was not possible to construct a functional correlation network for this group. Following light sheet imaging, ClearMap2.1 was used to register brains to the Allen Brain Atlas and detect fos+ cells. Functional correlation matrices were calculated for each group from log₁₀ c-fos values. Euclidean distances were calculated from these R values and hierarchical clustering was used to determine modules (highly connected groups of brain regions) at a tree-cut height of 50%. In males, alcohol access decreased modularity (3 modules in both frontloaders and non-frontloaders) as compared to water drinkers (7 modules). In females, an opposite effect was observed. Alcohol access (9 modules) increased modularity as compared to water drinkers (5 modules). These results suggest sex differences in how alcohol consumption reorganizes the functional architecture of networks. Next, key brain regions in each network were identified. Connector hubs, which primarily facilitate communication between modules, and provincial hubs, which facilitate communication within modules, were of specific interest for their important and differing roles. In males, 4 connector hubs and 17 provincial hubs were uniquely identified in frontloaders (i.e., were brain regions that did not have this status in male non-frontloaders or water drinkers). These represented a group of hindbrain regions (e.g., locus coeruleus and the pontine gray) connected to striatal/cortical regions (e.g., cortical amygdalar area) by the paraventricular nucleus of the thalamus. In females, 16 connector and 17 provincial hubs were uniquely identified which were distributed across 8 of the 9 modules in the female alcohol drinker network. Only one brain region (the nucleus raphe pontis) was a connector hub in both sexes, suggesting that frontloading in males and females may be driven by different brain regions. In conclusion, alcohol consumption led to fewer, but more densely connected, groups of brain regions in males but not females, and recruited different hub brain regions between the sexes. These results suggest target brain regions for future studies to try to manipulate frontloading behavior and more broadly contribute to the literature on alcohol’s effect on neural networks.</p>

Research identifying the relationship between inhibition and binge drinking in young adults is limited. Accordingly, this study aimed to identify which subcomponent(s) of inhibitory performance is most sensitive at discerning binge-drinking behavior among young adults through a longitudinal design. The sample consisted of 182 alcohol consuming college students (48.3% male) with a mean age of 21.04±1.83 years. Inhibitory processing and alcohol behavior were assessed at baseline and six months later at follow-up. Alcohol behavior was also evaluated throughout participation via 13 biweekly alcohol logs. Multiple regression analysis revealed that interference inhibition (Simon task) contributed to the prediction of the number of drinks consumed during binge drinking occasion among males. These findings suggest that specific subcomponents of response inhibition, and not others, are more suitable for predicting alcohol consumption habits. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

No. of bitstreams: 1 Beatriz Azevedo Moraes.pdf: 2597554 bytes, checksum: fbe5f48c5153f3acb37c26e3e5e3fb43 (MD5) Previous issue date: 2014-03-28 / The objective of this work was to investigate the eating behavior of three women who underwent bariatric surgery and propose an intervention for the control of food restriction and the intermittent access to palatable foods as a strategy to change an eating pattern said to be compulsive. Participated in this research three women who agreed to record their daily food ingestion, through an electronic self-monitoring and photo taking during four phases. The first, Baseline, was performed to assess the initial dietary pattern. In Phase 2, the participants were given tokens to exchange for gift cards, in case the electronic record was corresponding to the photo, to ensure the reliability of the record. In Phase 3.1, besides the reinforcement for correspondence, the participants were instructed to eat every three hours and in case of following this guidance, they would also receive the tokens. In Phase 3.2, the instruction and reinforcement were designed for the preparation and intake of a palatable portion of food of up to 150 kcal. During Phase 4, the suspension of the intervention occurred, and only the selfmonitoring and the photo were kept. Among the 3 participants, one (P3) interrupted her participation before the start of Phase 2. The results showed that for P1 and P2, binge eating during Baseline was classified by the quality and quantity of food ingested and after the intervention only the eating behavior before a certain quality of food (sugars and fats) seemed to have been evocative for the binge reporting. The data also showed the change of eating habits of P1 and P2, once the intervals between meals decreased and both began to ingest palatable foods in a more continuous and limited way. This change coincides with the decrease in the report of episodes said to be compulsive, indicating that the variables that the study aimed to alter seem, in fact, to be related to the improper eating behavior of the participants / O objetivo da presente pesquisa foi investigar o comportamento alimentar de três mulheres que realizaram a cirurgia bariátrica e propor uma intervenção para o controle da restrição alimentar e do acesso intermitente à alimentos palatáveis como estratégia de mudança do padrão alimentar dito compulsivo. Participaram da pesquisa três mulheres que concordaram em registrar diariamente sua alimentação, através de um automonitoramento eletrônico e da foto durante quatro fases. A primeira, Linha de Base, foi realizada para avaliar o padrão alimentar inicial de cada participante. Na Fase 2 as participantes receberam fichas para trocar por um vale-compras, caso o registro eletrônico fosse correspondente à foto, de forma a garantir a fidedignidade do registro. Na Fase 3.1, além do reforçamento para a correspondência, as participantes receberam instruções para se alimentar de três em três horas e caso seguissem a orientação também recebiam fichas. Na Fase 3.2, a instrução e o reforçamento foram delineados para a preparação e ingestão de uma porção diária de alimento palatável de até 150kcal. Durante a Fase 4, ocorreu a suspenção da intervenção, sendo mantido apenas o automonitoramento e a foto. Das 3 participantes, uma (P3) interrompeu sua participação antes do início da Fase 2. Os resultados mostraram que para P1 e P2 a compulsão alimentar durante a Linha de Base foi classificada através da qualidade e da quantidade de alimento ingerida e após a intervenção apenas o comportamento alimentar diante de determinada qualidade dos alimentos (açucares e gorduras) parece ter sido evocativa para o relato de compulsão. Os dados também apontaram a mudança dos hábitos alimentares de P1 e P2, uma vez que os intervalos entre as refeições diminuíram e ambas passaram a ingerir alimentos palatáveis de forma mais contínua e limitada. Esta mudança coincide com a diminuição no relato de episódios ditos compulsivos, indicando que as variáveis que o estudo se propôs a alterar parecem estar, de fato, relacionadas com o comportamento alimentar inadequado das participantes

Adolescence is a critical developmental period in which the brain emerges from an immature state to adulthood. This process of brain development is associated to greater cognitive capacity but also to altered emotional behaviour, such as anxiety and depressive symptoms; as well as increased sensation-seeking and risk taking behaviour. The proper development of brain and behaviour into adulthood can be negatively affected by external factors such as drug abuse and environmental conditions. This work consists firstly on, studying the impact of binge ethanol, 3, 4-Methylenedioxymethamphetamine (MDMA) and its combination in adolescent mice. Secondly, study the consequences of early-life stressful experiences (social isolation) into adulthood. Main results obtained from the first objective are that the combination of binge ethanol and MDMA induces emotional-like alterations. These alterations can be prevented by antidepressant treatment. In addition, MDMA induces memory impairments that may be associated to oxidative damage to specific proteins in the hippocampus. Neuroinflammation is also present after MDMA treatment, but not after binge ethanol treatment, in mice striatum. Metabolomic studies indicate that brain metabolism is altered after binge ethanol, MDMA or its combination. Even though these are only preliminary results, these alterations might be due to an imbalance in tryptophan metabolism. Regarding the second objective, our findings indicate that social isolation during adolescence induces an altered response to novel and stressful situations. These alterations are probably due to altered HPA axis activity. / L'adolescència és un període crític en el desenvolupament de l’individu en el qual el cervell va d’un estat immadur a l’edat adulta. Aquest procés va acompanyat d’una elevada capacitat cognitiva però també de freqüents alteracions de tipus emocional, com l’ansietat o els símptomes depressius, així com la cerca de sensacions de risc. Un bon desenvolupament del cervell i del comportament es pot veure negativament afectat per factors externs com són l’abús de drogues i les condicions ambientals desfavorables. Aquest projecte consisteix en primer lloc, a estudiar l'impacte de l’alcohol en excés, la 3, 4-Metilendioximetamfetamina (MDMA) i la seva combinació en ratolins adolescents. En segon lloc, estudiar les conseqüències en l’edat adulta d’experiències estressants durant l’adolescència. Els principals resultats obtinguts referents al primer objectiu són que la combinació d'alcohol en excés i MDMA provoca alteracions de tipus emocional. Aquestes alteracions poden ser previngudes pel tractament amb antidepressius. A més, la MDMA indueix un deteriorament de la memòria que pot estar associada amb el dany oxidatiu a proteïnes específiques de l'hipocamp. També s’ha observat una resposta neuroinflamatòria en el cos estriat dels ratolins després del tractament amb MDMA, però no després del tractament amb etanol en excés. Finalment, estudis de metabolòmica indiquen que el metabolisme cerebral es veu alterat després de l’alcohol en excés, la MDMA o la seva combinació. Tot i que només són resultats preliminars, aquestes alteracions poden ser conseqüència d'un desequilibri en el metabolisme del triptòfan. Referent al segon objectiu, els nostres resultats indiquen que l'aïllament social durant l’adolescència indueix una resposta alterada a situacions novelles i estressants. Aquestes respostes anormals són probablement conseqüència d’alteracions en l’activitat de l’eix HPA.

Chlamydia trachomatis (CT) can cause infertility and is the most common sexually transmitted infection (STI) of bacterial origin in Europe. Surveys in seven countries estimated a population prevalence of 1.4-3.0 % in people 18 to 44 years. Approximately 87% of those diagnosed in Sweden are 15-29 years. Since 1997, with the exception of 2009-2010, despite all efforts, CT has increased steadily in many European countries including Sweden. That made us investigate risk factors associated with catching STIs, especially CT. In Sweden partner notification is mandatory by law when a patient is diagnosed with CT. Centralised partner notification, performed by a few experienced counsellors, and evaluation of the sexual history for at least 12 months back in time, shows superior results compared to other studies. Phone-interviews are a good option in remote areas. “The Västerbotten model” for partner notification fulfils these criteria and our evaluation has functioned as a model for changing recommendations of partner notification in Sweden. Preventing CT by primary prevention such as information and counselling is, however, still of great importance. We investigated whether it was necessary to test for CT in the throat. We found that patients testing positive for pharyngeal CT neither had more symptoms or signs nor a sexual history that differed from others. We therefore believe that we will find most or all of these patients by conventional testing of urine and cervical/vaginal samples. We wanted to further identify risk factors among patients attending a clinic for sexually transmitted infections to enable individualized care depending on risk. None or inconsistent use of condoms with new/temporary partners in combination with having at least one new/temporary partner within the past 6 months could identify persons with risk behaviour and at increased risk of CT (re)infection. Additional information about whether the condom was used during the whole intercourse did not add any risk of infection. A drop-in reception is a good contribution to an opportunistic screening approach. The rate of CT infected is high and the clinic attracts men and individuals ≥25 years old at risk of infection, groups which usually have a reduced test rate. The mean age was 28 years and 58% of the patients were men. The figure of correct condom usage is very low indicating the need for risk reducing counselling also in this grown-population. Among adult STI patients anxiety was common and depression uncommon. Neither was linked to high risk sexual behaviour nor ongoing CT infection. Hazardous alcohol consumption, however, was common and linked to anxiety and high risk sex. We conclude that preventive work can not only focus on STI prevention, but must consider the high frequency of hazardous alcohol consumption, which probably is contributing to sexual risk behaviour.

To investigate whether there are different patterns of development for binge eating and purging behavior among pre-adolescent and early adolescent girls, I conducted trajectory analyses of those behaviors in 938 girls across eight waves of data from the spring of 5th grade (the last year of elementary school) through the spring of 9th grade (the first year of high school). Analyses revealed four separate developmental trajectories for binge eating behavior (labeled none, increasing, decreasing, and high steady) and three separate developmental trajectories for purging behavior (labeled none, dabble, and increasing). Fifth grade scores on risk factors that were both personality-based (negative affect and negative urgency) and learning-based (expectancies for reinforcement from eating and from thinness) differentiated among the trajectory groups, in some cases before the groups differed in the target behaviors. These findings are the first, to my knowledge, to examine developmental trajectories for eating disorder onset in youth as young as elementary school. Clinical implications are discussed.

Métodos: Ensaio Clínico Randomizado, paralelo, com dois braços, duplo cego, placebo-controlado, de quatro semanas, realizado em uma instituição pública do estado de São Paulo - Brasil. Os participantes foram indivíduos sadios de ambos os sexos, com idade de 20 a 59 anos, alfabetizados, com sobrepeso ou obesidade pelos critérios da Organização Mundial da Saúde (IMC ≥ 25 Kg/m2) e com ansiedade moderada ou elevada pelos critérios do Inventário de Ansiedade-Estado (IDATE com Escore ˃ 34). Para a coleta de dados utilizou-se questionário sócio-demográfico e clínico, escala de ansiedade IDATE-ESTADO, Escala de Compulsão Alimentar Periódica (ECAP) e Questionário de Padrão do Sono de Pittsburg (PSQI), aferição da pressão arterial e eletrocardiograma, no momento inicial e após 4 semanas de tratamento. A análise estatística foi realizada calculando o delta para expressar a diferença das médias das medidas de desfecho entre os momentos de avaliação dentro de cada grupo estudado. Em seguida, utilizou-se o Teste de Mann-Whittney para a comparação entre grupos. Análise multivariada foi realizada utilizando modelos de regressão linear robusta simples e múltipla. Resultados: A coleta de dados ocorreu entre setembro de 2015 e janeiro de 2017 e a amostra foi constituída por 40 participantes no grupo placebo e 41 no grupo floral, principalmente pelo sexo feminino (92,5% e 90,2%), com idade média de 42,9 e 38,5 anos e IMC médio de 34,31 e 33,5 kg/m2 nos grupos placebo e floral respectivamente. A análise multivariada mostrou redução estatisticamente significante no grupo floral quando comparado ao grupo Placebo nas seguintes variáveis: IDATE (β=-0,190; p<0,001), PSQI (β=-0,160; p=0,027), ECAP (β=-0,226; p=0,001) e frequência cardíaca de repouso (β=-0,07; p=0,003). Conclusão: indivíduos tratados com terapia floral apresentaram redução de sintomas ansiosos, melhora no padrão de sono, redução nos sintomas de compulsão alimentar e diminuição na frequência cardíaca de repouso maior do que aqueles tratados com placebo. Esse resultado evidencia a importância e a necessidade de ações de saúde em prol da redução da ansiedade e sintomas associados em indivíduos com sobrepeso ou obesidade e fortalece a terapia floral como prática integrativa e complementar na área da saúde. / Introduction: The prevalence of obesity is increasing among adults worldwide and is associated with an increased risk of morbidity and mortality, as well as a reduction in life expectancy with negative health outcomes. It is also associated with other pathologies such as anxiety disorder, compulsive behavior and imbalance in sleep behavior. Although obesity is considered a predictable pathology, there are still great difficulties associated with weight loss and its maintenance by modifying lifestyle in the current scenario, showing the need to investigate factors that address not only weight but also pathologies and / or associated symptoms. Floral therapy is part of an emerging field of vibrational therapies, and its essences, made from wild plants, flowers and field trees, work by harmonizing emotions, not by treating physical conditions. In this context, it appears as an alternative for the relief of the anxious behavior of individuals, as there is no incompatibility with other treatment methods, and can be indicated to a large number of people at any stage of life. Objective: To identify whether treatment with floral therapy changes the degree of anxiety of overweight or obese individuals, with consequent improvement in sleep pattern, reduction in binge eating symptoms, reduction in resting heart rate and improvement in blood pressure levels. Methods: Randomized, parallel, two-arm, double-blind, placebo-controlled, four-week clinical trial conducted at a public stitution in the state of São Paulo - Brazil. Participants were healthy individuals of both sexes, aged 20-59 years, literate, overweight or obese according to World Health Organization criteria (BMI ≥ 25 kg / m2) and with moderate or high anxiety according to the criteria of the State - Trait Anxiety Inventory (STAI) (STAI with Score ˃ 34). Data were collected using a sociodemographic and clinical questionnaire, State - Trait Anxiety Inventory (STAI), Binge-Eating Scale (BES) and Pittsburgh Sleep Quality Index (PSQI), blood pressure and electrocardiogram and after 4 weeks of treatment. Statistical analysis was performed by calculating the delta to express the difference of means of outcome measures between the moments of evaluation within each group studied. Then, the Mann-Whittney test was used for the comparison between groups. Multivariate analysis was performed using simple and multiple robust linear regression models. Results: Data collection occurred between September 2015 and January 2017, and the sample consisted of 40 participants in the placebo group and 41 in the floral group, mainly female (92.5% and 90.2%), with age mean of 42.9 and 38.5 years and mean BMI of 34.31 and 33.5 kg / m2 in the placebo and floral groups, respectively. The multivariate analysis showed a statistically significant reduction in the floral group when compared to the placebo group in the following variables: IDATE (β = -0.190, p <0.001), PSQI (β = -0.160, p = 0.004), ECAP (β = -0.226; p = 0.001) and resting heart rate (β = -0.07, p <0.001). Conclusion: Individuals treated with floral therapy had reduced anxiety symptoms, improved sleep patterns, reduced binge eating symptoms, and decreased resting heart rate greater than those treated with placebo. This result evidences the importance and necessity of health actions in favor of the reduction of anxiety and associated symptoms in overweight or obese individuals and strengthens floral therapy as an integrative and complementary practice in the health area.
