Association between Self-Perception of Chewing, Chewing Behavior, and the Presence of Gastrointestinal Symptoms in Candidates for Bariatric Surgery

Given the changes in the digestive tract post-bariatric surgery, adapting to a new pattern of eating behavior becomes crucial, with special attention to the specifics of chewing mechanics. This study aimed to investigate the association between self-perception of chewing, chewing behavior, and the presence of gastrointestinal symptoms in preoperative patients undergoing bariatric surgery. Sixty adult candidates for bariatric surgery at a public hospital in Belém (Brazil) were analyzed. Participants predominantly exhibited unilateral chewing patterns (91.6%), a fast chewing rhythm (73.3%), a large food bolus (80%), liquid intake during meals (36.7%), and 41.7% reported that chewing could cause some issue. Significant associations were found between the perception of causing problems and chewing scarcity (p = 0.006), diarrhea (p = 0.004), absence of slow chewing (p = 0.048), and frequent cutting of food with front teeth (p = 0.034). These findings reveal a relationship between the perception of chewing problems and chewing scarcity, presence of diarrhea, and fast chewing.

Eating Behavior and Nutritional Profile of Children with Autism Spectrum Disorder in a Reference Center in the Amazon

There is no single pattern for the evolution of the nutritional status of children with autism spectrum disorder (ASD). Previous studies have found a tendency towards food selectivity with food monotony and difficulties with food texture in children with ASD, but studies in this area, especially in Brazil, are still scarce. The nutritional profile and changes in eating behavior were analyzed in patients with autism spectrum disorder assisted at a reference center in Belém. Eating behavior was assessed using the Labyrinth Scale, nutritional status assessment through weight and height (to calculate body mass index-BMI), and consumption food through the 24 h reminder. A total of 80 children of both sexes participated in the study, the majority of whom were male (80%), 47.5% eutrophic, while for the food consumption of the children evaluated, there was an average energy consumption of 1911 kcal daily, with 57.3%, 15.4%, and 27.3% of carbohydrates, proteins, and lipids, respectively. In relation to eating behavior, the highest averages were demonstrated in the domains of food selectivity, behavioral aspects, and mealtime skills. Masticatory motor scores showed a positive correlation with weight, BMI, and the amount of energy consumed by the child. The gastrointestinal symptoms score showed a negative correlation with the child's age. Regarding mealtime skills, a negative correlation was observed with the proportion of carbohydrates in the diet and a positive correlation with the proportion of lipids consumed in the children's diet. Therefore, knowing the main changes in eating behavior is important to ensure a complete and safe approach for each patient.

Factors associated with grazing behavior in candidates for bariatric surgery at a hospital in the Amazon

Blackground

To assess grazing behavior and associated factors in candidates for bariatric surgery monitored at a public hospital that is a reference in the care of people with severe obesity.

Methods

Cross-sectional analytical study, with candidates for bariatric surgery of both genders, treated in a public hospital in the Amazon. To assess grazing behavior, the Repetitive Eating Questionnaire was used, and to investigate patterns of eating behavior, the Three Factor Eating Questionnaire was used, which assesses: Emotional Eating, Cognitive Restriction and Uncontrolled Eating. Sociodemographic information was obtained through self-report and the description of medication use through the medical record. Body mass index (BMI) was also calculated by measuring weight and height. The SPSS program, v. 21.0 was used. The study was approved by the Research Ethics Committee.

Results

A total of 205 participants were evaluated, with a mean age of 37.5 ± 8.6 years, the majority (93.7%) being women and the majority (59.5%) was not also using medication to lose weight. About 66.3% of the participants had compulsive grazing. The factor with the highest score was cognitive restriction (p < 0.001). Individuals who used weight loss drugs had higher scores in the cognitive restriction factor (p = 0.015) and lower scores for uncontrolled eating (p = 0.008), compulsive grazing (p = 0.021) and non-compulsive grazing (p = 0.034).

Conclusion

Linear regression showed that emotional eating and uncontrolled eating were predictors of both compulsive grazing and non-compulsive grazing behavior. It was observed that grazing behavior, cognitive restriction, emotional eating and uncontrolled eating are present and correlated in the studied patients. In addition, the use of weight loss drugs seems to help reduce dysfunctional eating behaviors in patients with severe obesity.

Relationship between Quality of Life and Adult Attachment Factors in Mothers of Children with and without Type 1 Diabetes

The mothers of children with a specific clinical situation such as type 1 diabetes mellitus may have a higher level of stress, causing a worse perception of their quality of life, greater anxiety, and greater avoidance (adult attachment factors). The objective of this research was to verify if there is a relationship between the adult attachment factors of mothers of children with and without type 1 diabetes mellitus and the perception of the quality of life of these mothers. This survey was carried out from July to September 2022, with mothers of children aged 5 to 10 years, with and without diabetes. The data were collected through an online questionnaire, with socioeconomic data from the attachment scale Experience in Close Relationship-(Reduced), and the questionnaire on the quality of life, the WHOQOL-abbreviated questionnaire. For statistical analysis, the Statistical Package for Social Science 24 was used. A total of 45 mothers of children with DM1 and 55 mothers of healthy children were evaluated. The mothers of children with DM1 had a worse perception of their quality of life when compared to the mothers of healthy children (p < 0.05), with no difference in terms of the attachment style. Therefore, it is understood that actions aimed at improving the quality of life of these mothers are necessary.

Characteristics of carbohydrate counting practice associated with adequacy of glycated hemoglobin in adults with type 1 diabetes mellitus in Brazil

Background

The Carbohydrate Counting (CC) is directly associated with achieving glycemic control by people with Type 1 Diabetes Mellitus (T1DM). Therefore, this study aims to analyze characteristics of the CC practice associated with the adequacy of glycated hemoglobin (HbA1c) in adults with T1DM in Brazil.

Methods

The study was cross-sectional, carried out using an online form with questions about knowledge of CC, clinical, anthropometric, sociodemographic data, follow-up with health professionals and understanding of the concepts of CC. Pearson's chi-square test and binomial logistic regression analysis (p<0.05) were applied.

Results

173 adults participated, of which 57.2% had increased HbA1c (≥7%). Having the diabetes duration <10 years (p=0.006), performing the CC at lunch (p=0.040) and dinner (p=0.018), using specific applications to perform the CC (p=0.001), having learned to perform CC with a nutritionist (p=0.037) and knowing how to correctly define the concepts of food bolus (p=0.001), correction bolus (p<0.001) and insulin/carbohydrate ratio (p<0.001) was associated with having adequate HbA1c (<7%). Participants who were undergoing CC practice were 3.273 times more likely to have adequate HbA1c and participants with diabetes duration <10 years were 2.686 times more likely to have adequate HbA1c.

Conclusion

It was concluded that variables transversal to CC favor adequate HbA1c values in adults with T1DM and that practicing CC and having a diabetes duration of less than 10 years are predictive factors of having adequate HbA1c.

Correlations between Nutritional Status and Quality of Life of People with Parkinson's Disease

Parkinson's disease (PD) is a neurodegenerative condition that can impact the nutritional status, and such impact seems to be related to the quality of life (QoL).

OBJECTIVE

To evaluate the correlation between anthropometric variables and the QoL of people with Parkinson's disease (PD).

METHODS

This is a cross-sectional, descriptive, and analytical study, carried out through the collection of anthropometric data and application of the Parkinson's Disease Questionnaire PDQ-39.

RESULTS

33 individuals (23 male) diagnosed with PD participated in the research, with a mean age of 58.9 ± 11.6 years. We observed overweight in 45.4% of participants. The perception of QoL showed lower scores for the subjects in the dimensions of body discomfort (75.3 ± 16.6), social support (62.7 ± 15.7), and mobility (61.0 ± 23.6). The correlation between the total QoL score and age (model 1, B = 0.347; CI 0.004-0.902; p = 0.048), which remained statistically significant in the multiple linear regression, regardless of gender (model 2, B = 0.365; CI 0.016-0.937; p = 0.043) and BMI (model 3, B = 0.363; CI 0.006-0.943; p = 0.047), suggests that, in the participants of this study, this relationship does not depend on gender and nutritional status.

CONCLUSION

The perception of QoL was worse in the dimensions of body discomfort, social support, and mobility, worsening with advanced age. Correlations between the worst scores in QoL dimensions and nutritional status were observed. A positive correlation was also identified between age and overall PDQ-39 score, regardless of gender and nutritional status.

Relationship between Determinants of Food Choices and Socioeconomic and Demographic Factors of Individuals with Hepatitis B and C in the Amazon Region

Knowing the determinants of food choices allows the nutritionist to develop more assertive guidelines considering biopsychosocial factors to produce effective changes in eating practices. This cross-sectional, descriptive, and analytical study aimed to test the correlation between the determinants of food choices and the socioeconomic and demographic factors of individuals with hepatitis B and C. Patients with hepatitis B and/or C aged between 20 and 74 years were evaluated from August 2020 to August 2021. Their socioeconomic and demographic data and clinical data were collected, and The Eating Motivation Survey (TEMS) was applied. A total of 145 individuals were evaluated, with a mean age of 53.54 ± 12.14 years. There were positive weak correlations between gender (p² = 0.193; p = 0.020) and age (p² = 0.177; p = 0.033) with the scale "preference"; negative correlations between age and the scales "price" (p² = -0.204; p = 0.014) and "emotion control" (p² = -0.168; p = 0.044); negative correlations between education and the scales "convenience" (p² = -0.172; p = 0.039) and "social norms" (p² = -0.206; p = 0.013); and income showed a negative correlation with "price" (p² = -0.208; p = 0.012) and a positive correlation with "weight control" (p² = 0.186; p = 0.025). These findings contribute to the development of more realistic and feasible eating strategies that favor food autonomy.

Adherence to Online Nutritional Monitoring Was Associated with Better Food Habits in People with T1DM during the COVID-19 Pandemic in Brazil

Until this moment, no research has been found that has assessed adherence to online nutritional monitoring by adults with Diabetes Mellitus Type 1 (T1DM) during the pandemic. This article aims to analyze the association between eating habits and adherence to nutritional online care by adults with T1DM during social distancing because of the COVID-19 pandemic in Brazil. A cross-sectional study was carried out in July 2020. An online form was used to collect sociodemographic data, financial status, eating habits, carrying out online nutritional monitoring, and adherence to social distancing. Pearson's chi-squared test was performed with adjusted residual analysis and binomial logistic regression analysis (p < 0.05). Out of the 472 adults, only 8.9% had consulted with a nutritionist. Doing nutritional monitoring online during social distancing was associated with a reduction in the consumption of ultra-processed foods (p = 0.021), eating more servings of fruit (p = 0.036), and doing carbohydrate counting (CC) more frequently (p = 0.000). Doing nutritional monitoring online increased adherence to carbohydrate counting by 2.57 times and increased the consumption of fruits by 0.423 times. Therefore, nutritional monitoring, even if performed remotely, can influence the acquisition and maintenance of healthier eating habits, in addition to assisting adherence to the practice of CC.

Changes in Physical Activity Associated with Mental Health in People with Type 1 Diabetes during the COVID-19 Pandemic

The social isolation carried out during the COVID-19 pandemic contributed to physical inactivity and impacted people's mental health, with physical activity being an important pillar in the treatment of Type 1 Diabetes Mellitus (T1DM). Thus, this study aims to verify whether there is an association between the perception of mental health and the practice of physical activity in individuals with T1DM during social isolation in the COVID-19 pandemic in Brazil. This was a cross-sectional study conducted in July 2020, with 472 adults with T1DM, using an online form to collect sociodemographic, mental health and physical activity data during social isolation. The Chi-Square test of independence was performed with adjusted residuals analysis (p < 0.05). A total of 51.3% of the participants remained sedentary or stopped doing physical activity during the period of social isolation. There was an association between being interested in performing daily activities (p = 0.003), not feeling depressed (p = 0.001), feeling slightly irritated (p = 0.006), having slight problems with sleep (p = 0.012) and practicing physical activity. There was also an association between maintaining physical activity and not feeling depressed (p = 0.017) and feeling very slightly irritated (p = 0.040). Adults with T1DM who practiced physical activity during the period of social isolation due to the COVID-19 pandemic showed better aspects of mental health.

Associations between Orthorexia Nervosa, Body Self-Image, Nutritional Beliefs, and Behavioral Rigidity

Possible correlations between orthorexic self-reports, unhealthy nutritional beliefs, behavioral rigidity related to following rules, and distortion of body self-image were investigated. In total, 246 university students of both sexes, from different areas of knowledge, answered a sociodemographic form, the Ortho-15, the Body Shape Questionnaire, the Rigidity Scale, and a Nutritional Beliefs Form. Orthorexic self-reports were observed in 73 men and 106 women. A positive correlation was found between females and orthorexic self-reports (p = 0.036), and severe distortion of body self-image (p = 0.002) and between the latter, the behavioral rigidity scale (p2 = 0.189; p = 0.001), and female sex (p2 = 0.245; p < 0.000). In the logistic regression, women were 1.83 times more likely to present orthorexic behaviors than men. The creation of prevention and treatment strategies aimed at women is suggested and it recommended that studies investigating whether the presence of orthorexic self-reports is a risk factor for the development of eating disorders are carried out.

Adherence to Carbohydrate Counting Improved Diet Quality of Adults with Type 1 Diabetes Mellitus during Social Distancing Due to COVID-19

To control glycemic variability in people with Type 1 diabetes mellitus (T1DM), it is essential to perform carbohydrate counting (CC), a strategy that ensures better quality of life for these patients. Thus, this study aims to analyze potential factors associated with adherence to CC in adults with T1DM during social distancing due to COVID-19 in Brazil. This was a single cross-sectional study carried out in July 2020. An online form was used to collect sociodemographic and economic data on the purchasing of supplies and food, as well as social distancing. The Chi-square test was performed with adjusted residuals analysis and a binomial logistic regression analysis (p < 0.05). Of 472 adults, 37.71% reported performing CC in the same frequency as before social distancing. There was an association between performance of CC and the type of city (p = 0.027), family income (p = 0.000), use of financial emergency aid (p = 0.045), type of insulin administration and glycemic monitoring (p < 0.000), and cooking more (p = 0.012). Participants who maintained or reduced consumption of ultra-processed foods were 0.62 times more likely to adhere to CC (OR 0.626, 95% IC: 0.419−0.935) and participants who cooked more were 1.67 times more likely to adhere to CC (OR 1.67, 95% CI: 1.146−2.447). There are still people with T1DM who did not know about and did not use CC method, which highlights the need for diabetes education.

Relationship between Eating Behavior, Quality of Life and Weight Regain in Women after Bariatric Surgery

Individuals undergoing bariatric Surgery (BS) may have long-term weight regain. There is a need to investigate factors that may be related to this and if they can interfere with Quality of Life (QOL). This study aims to evaluate the relationship between eating behavior, perception of QOL, and weight regain in women after 24 months of bariatric surgery. This was a transversal study with 50 adult women residents in the city of Belém, Brazil. Sociodemographic, anthropometric, eating behavior (Three-Factor Eating Questionnaire—TFEQ-21) and perception of QOL (Item Short Form Healthy Survey—SF-36) data were collected. In 60% (n = 30) there was weight regain (≥15%), with a mean weight regain of 23.3% (±18.4). Emotional eating was the most frequent pattern (p = 0.047). Regarding QOL, the functional capacity and limitation due to physical aspects domains had a better perception (p < 0.0001). Women without weight regain showed a better perception of the functional capacity aspects (p = 0.007), limitation due to physical aspects (p = 0.044), social aspects (p = 0.048), and general physical components (p = 0.016) and also had an inverse association with the perception of QOL in physical components (p = 0.008). Patterns of eating behavior and weight regain can damage the perception of QOL, especially physical capacity. Long-term follow-up is essential to evaluate the behavior of people who have undergone BS in order to prevent weight regain and QOL damage.

Correlation between Anxiety Symptoms and Perception of Quality of Life in Women with More Than 24 Months after Undergoing Bariatric Surgery

Purpose: To analyze the correlation between anxiety symptoms and perceived quality of life in women more than 24 months after undergoing bariatric surgery. Methods: Cross-sectional, descriptive and analytical study, carried out with women who underwent bariatric surgery after at least 24 months. To assess the level of anxiety symptoms, the Beck Inventory was used and to assess the perception of quality of life, the Item Short Form Healthy Survey was applied. Results: Of the 50 participants, 36.0% had reports indicative of moderate symptoms and 64.0% had severe symptoms of anxiety. The domains of quality of life that correlated with better perception were pain (p < 0.001), functional capacity (p = 0.013), general health status (p = 0.018), social aspects (p < 0.001), and mental health (p < 0.001). In linear regression, a significant inverse correlation was found between the general emotional component of quality of life and anxiety score (β = −0.546; CI −1.419; −0.559; p < 0.001) and between the general physical component of quality of life and anxiety score (β = −0.339; CI −0.899; −0.131; p = 0.010), both independent of weight regain and surgery time. Conclusions: It was observed that moderate to severe anxiety symptoms seem to interfere with the perception of quality of life, regardless of weight regain and surgery time.

Health-related quality of life in T1DM patients after high-dose cholecalciferol supplementation: data from a pilot clinical trial

BACKGROUND

Type 1 Diabetes Mellitus (T1DM) impacts health-related quality of life (HRQoL). Cross-sectional studies suggest that low levels of vitamin D (VD) may impair HRQoL, however, the effect of VD supplementation on quality of life in T1DM patients has not yet been clarified. Our study evaluated the effects of high-dose VD supplementation on HRQoL in T1DM.

METHODS

We performed a prospective study with 64 patients receiving cholecalciferol (4000 IU/day for patients with 25-OH-vitamin D [25(OH)D] between 30 and 60 ng/mL, and 10,000 IU/day for those with 25(OH)D below 30 ng/mL) for 12 weeks, as part of a research protocol. HRQoL was assessed with EuroQol instruments (EQ-5D and EQ-VAS).

RESULTS

There was an improvement in global EQ-5D index, and analysing specifically the EQ-5D domains, we observed an improvement in mobility (1.3 ± 0.6 versus 1.1 ± 0.3, p < 0.01). Evaluating possible outcome influencing variables, we detected a reduction in albuminuria at the end of the trial, without changes in BMI, lipids, blood pressure, glycemic control and insulin doses. We found correlations between final albuminuria and the dimensions: mobility (r = 0.6; p < 0.01), personal care (r = 0.7; p < 0.01), pain and discomfort (r = 0.6; p < 0.01) and habitual activities (r = 0.6; p < 0.01), suggesting an association between albuminuria reduction and the impact of VD supplementation on HRQoL.

CONCLUSION

Our data showed that high doses of cholecalciferol supplementation can improve HRQoL in patients with T1DM, and the reduction of albuminuria seems to be an important factor in this context.

Hepatitis C virus eradication on glycemic control and insulin resistance

OBJECTIVE

To review data regarding the effects of hepatitis C virus eradication on glycemic control and insulin resistance.

METHODS

This is an integrative literature review, carried out in the PubMed, SciELO, and Lilacs databases. Studies published in the past five years that were fully available, written in English or Portuguese, and have addressed the effects of eradication of the hepatitis C virus on glycemic control and insulin resistance were selected.

RESULTS

Nine studies were selected. Among the results found, it was observed that there is no consensus on the effects of viral eradication on glycemic control and IR, as some authors show an eventual improvement in insulin resistance and glycemic control, while other studies indicate that there are no significant differences between the parameters evaluated after viral eradication.

CONCLUSIONS

Although there is a relationship between hepatitis C virus infection and the development of insulin resistance and type 2 diabetes mellitus and recent advances in research, it was observed that there is no consensus on improving insulin resistance and glycemic control after antiviral treatment, probably due to methodological differences between studies. However, it emphasizes the need to guide people diagnosed with hepatitis C, regarding changes in lifestyle, encouragement of multidisciplinary monitoring, and control of other risk factors.

Metodologia e indicadores para monitoramento da NBCAL em estabelecimentos comerciais e serviços de saúde: estudo multicêntrico (Multi-NBCAL)

A Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeiras (NBCAL), vigente no Brasil desde 1988, ainda é sistematicamente infringida, expondo mães e familiares ao marketing ilegal de produtos que competem com o aleitamento materno. O objetivo foi descrever metodologia de estudo multicêntrico e propor indicadores padronizados para monitoramento da NBCAL. Estudo Multicêntrico para Monitoramento da NBCAL (Multi-NBCAL) conduzido em sete cidades brasileiras: Rio de Janeiro; São Paulo; Ouro Preto (Minas Gerais); Florianópolis (Santa Catarina); Brasília (Distrito Federal); João Pessoa (Paraíba) e Belém (Pará). Instrumentos de avaliação foram adaptados do NetCode/WHO e da IBFAN Brasil (Rede Internacional em Defesa do Direito de Amamentar) para condução de dois inquéritos: (1) avaliação do cumprimento da NBCAL em estabelecimentos comerciais e das práticas e conhecimento dos seus gerentes sobre a NBCAL; (2) avaliação em maternidades da interação da indústria de alimentos infantis com profissionais de saúde e mães. Foram elaborados cinco indicadores para avaliação do cumprimento da NBCAL em estabelecimentos comerciais; sete indicadores para avaliar conhecimentos e práticas dos seus responsáveis; cinco indicadores para avaliar a oferta de incentivos a maternidades, profissionais de saúde e mães pelas indústrias e cinco indicadores para avaliar conhecimento e práticas de profissionais de saúde quanto à NBCAL. A metodologia de avaliação da NBCAL, com a proposta de indicadores padronizados, permite a comparabilidade de estudos sobre o tema. A utilização desses indicadores em inquéritos periódicos, nacionais ou regionais, pode contribuir para monitorar o grau de implementação da NBCAL no Brasil.

Association Between 25(OH)Vitamin D, HbA1c and Albuminuria in Diabetes Mellitus: Data From a Population-Based Study (VIDAMAZON)

BACKGROUND

The effect of glycemic control on diabetic kidney disease (DKD) is well known. Recent evidence has suggested that Vitamin D (VD) may have a nephroprotective effect in diabetes, but the relationship between VD, glycemic control, and albuminuria has yet to be clarified.

OBJECTIVE

Evaluate the relationship between 25-hydroxy-vitamin D [25(OH)D], HbA1c, and albuminuria in Diabetes Mellitus (DM).

PATIENTS AND METHODS

Cross-sectional study with 1576 individuals with DM who had 25(OH)D, HbA1c, and albuminuria levels measured. Patients with abnormal creatinine levels were excluded, in order to avoid interference on VD levels by impaired kidney function.

RESULTS

Patients with HbA1c ≥7% had lower 25(OH)D when compared to patients with HbA1c <7% (29.7 ± 10.2 vs 28.1 ± 9.9 ng/ml, p = 0.003) and 25(OH)D levels seems to predict 1.5% of HbA1c behavior. The 25(OH)D concentrations in patients with normoalbuminuria were higher than the levels observed in those with micro or macroalbuminuria (29.8 ± 9.0 vs 26.8 ± 8.6 and 25.1 ± 7.6, respectively, p = 0.001), patients who had 25(OH)D <20 ng/ml and 25(OH)D <30 ng/ml were at a higher risk of presenting albuminuria [OR = 2.8 (95% CI = 1.6 - 4.9), p<0.001, and OR = 2.1 (95% CI = 1.3 - 4.6), p<0.001, respectively]. In our regression model, albuminuria was influenced by HbA1c (r² = 0.076, p<0.00001) and 25(OH)D (r² = 0.018, p = 0.002) independently.

CONCLUSION

Our study found an association between vitamin D levels, HbA1c and DKD. Additionally, our data suggest that the association between urinary albumin excretion and vitamin D levels is independent of glycemic control in patients with diabetes. Even though our patients presented normal creatinine levels, it is necessary further prospective studies to confirm if this association precedes or not the loss of renal function.

Emotional eating behavior hinders body weight loss in women after Roux-en-Y gastric bypass surgery

OBJECTIVE

Successful weight loss and maintenance after Roux-en-Y gastric bypass (RYGB) may be related to eating behavior. The aim of this study was to assess the eating behavior domains that prevail in women during the RYGB postoperative period and their associations with surgery outcome.

METHODS

This cross-sectional study investigated eating behavior in 95 women (47.3 ± 9.8 y old)  ≥ 2 y after Roux-en-Y gastric bypass. Patients were grouped according to surgery outcome: successful group (SG; n = 67), defined as having lost ≥ 50% of the preoperative excess weight loss (EWL), and an unsuccessful group (UG; n = 28). Mean postoperative time was 59.5 ± 21.2 mo (55.7 ± 19.9 in the SG and 68.6 ± 21.9 in the UG). The short version of the Three-Factor Eating Questionnaire was used to assess cognitive restraint, emotional eating, and uncontrolled eating behaviors. Multivariate analysis was used to investigate associations between eating behavior scores and EWL.

RESULTS

The highest score in both groups was for the cognitive restraint domain, followed by emotional and uncontrolled eating. Emotional eating was negatively associated with percentage of EWL (β = -0.286; P = 0.033), regardless of age, educational attainment, and postoperative time.

CONCLUSION

The cognitive restraint domain was the main type of eating behavior observed, and patients with higher emotional eating score were at a higher risk for having insufficient weight loss after RYGB. These results indicate the relevance of monitoring emotional components during the long-term nutritional follow-up of bariatric patients to achieve better surgery outcomes.

Whey Protein Supplementation Enhances Body Fat and Weight Loss in Women Long After Bariatric Surgery: a Randomized Controlled Trial

BACKGROUND

The ideal nutritional approach for weight regain after bariatric surgery remains unclear.

OBJECTIVE

The objective of this study is to assess the effect of whey protein supplementation on weight loss and body composition of women who regained weight 24 or more months after bariatric surgery.

METHODS

This is a 16-week open-label, parallel-group, randomized controlled trial of women who regained at least 5 % of their lowest postoperative weight after a Roux-en-Y gastric bypass (RYGB). A total of 34 participants were treated with hypocaloric diet and randomized (1:1) to receive or not supplementation with whey protein, 0.5 g/kg of the ideal body weight. The primary outcomes were changes in body weight, fat free mass (FFM), and fat mass (FM), evaluated by tetrapolar bioelectrical impedance analysis (BIA). Secondary outcomes included resting energy expenditure, blood glucose, lipids, adiponectin, interleukin 6 (IL-6), and cholecystokinin levels. Statistical analyses included generalized estimating equations adjusted for age and physical activity.

RESULTS

Fifteen patients in each group were evaluated: mean age was 45 ± 11 years, body mass index (BMI) was 35.7 ± 5.2 kg/m², and time since surgery was 69 ± 23 months. Protein intake during follow-up increased by approximately 75 % in the intervention group (p = 0.01). The intervention group presented more body weight loss (1.86 kg, p = 0.017), accounted for FM loss (2.78, p = 0.021) and no change in FFM, as compared to controls (gain of 0.42 kg of body weight and 0.6 kg of FM). No differences in secondary outcomes were observed between groups.

CONCLUSIONS

Whey protein supplementation promoted body weight and FM loss in women with long-term weight regain following RYGB.

Poor diet quality and postoperative time are independent risk factors for weight regain after Roux-en-Y gastric bypass

OBJECTIVE

In this study, multivariate analyses was used to investigate factors associated with weight regain long after Roux-en-Y gastric bypass.

METHODS

This retrospective study comprised 80 patients (88.8% female) with at least 24 mo of postoperative time. Weight regain was defined as an increase of at least 10% of the lowest postoperative weight. The following data were collected: demographic characteristics, eating behavior, food intake, diet quality measured by the Healthy Eating Index, level of physical activity, follow-up visit attendance, anthropometric history, and postoperative time. Multivariate logistic regression generated a controlled analysis, followed by calculation of the odds ratio (OR).

RESULTS

The mean postoperative time was 47.0 ± 18.0 mo. The mean pre- and postoperative body mass indexes were 49.8 ± 9.3 kg/m(2) and 33.6 ± 7.2 kg/m(2), respectively. Despite satisfactory postoperative weight loss, 23.7% of the patients regained weight. After controlling for confounders, only postoperative time (OR 1.08; P < 0.01) and Healthy Eating Index (OR 0.95; P = 0.04) remained associated with weight regain.

CONCLUSION

Patients with long-term obesity and poor diet quality were at high risk of weight regain. These results suggest the need of nutritional monitoring during the late postoperative period, paying special attention to eating patterns.

Notificações de violência doméstica, sexual e outras violências contra crianças no Brasil

O artigo tem como objetivo apresentar o quadro de violência doméstica, sexual e outras violências perpetradas contra crianças (0-9 anos) no Brasil no ano de 2010, baseando-se nas notificações de violência doméstica, sexual e outras violências registradas no SINAN - Sistema de Informação de Agravos de Notificação (VIVA Contínuo). São apresentados os números absolutos e relativos derivados das notificações sobre violências, discriminando-se entre crianças menores de 1 ano e aquelas entre 1-9 anos, devido às especificidades existentes nessas faixas etárias. Em todo o país, o número de notificações entre menores de 10 anos é baixo (16,9%). Foram constatadas diferenças quanto à distribuição das notificações por unidade da federação. Observou-se que poucos municípios notificaram violências ao SINAN-Net no ano de 2010 no país. Algumas diferenças foram encontradas entre notificações em menores de 1 ano de idade e notificações de crianças entre 1-9 anos de idade, como por exemplo em relação ao perfil da violência, da vítima e do agressor, e o encaminhamento do caso. A qualidade da informação das notificações é discutida mostrando nível elevado de ausência de registros em alguns campos da ficha. Falhas na informação podem prejudicar o conhecimento mais detalhado do fenômeno, interferindo nas ações de planejamento, organização e operacionalização dos serviços de saúde no país.

Grupo de hipertensos: o perfil dos participantes e a influência no controle da hipertensão

A Hipertensão Arterial Sistêmica é a mais freqüente das doenças cardiovasculares . são cerca de 17 milhões de portadores de hipertensão arterial no Brasil. Apresenta características específicas do processo de cronicidade e multiplicidade de fatores associados; longo curso assintomático, além da evolução para complicações. Portanto, cada vez mais se comprova a necessidade de uma abordagem coletiva e multidisciplinar para se obter resultados mais consistentes e duradouros no controle da hipertensão arterial. Esse trabalho objetiva avaliar o perfil dos participantes do grupo de hipertensos segundo o sexo, a faixa etária, a renda familiar e per capita, a ocupação, a participação em grupos comunitários, o tipo de serviço de saúde ao qual recorreria em caso de doença, a freqüência no grupo de hipertensos e a influência deste grupo no que se refere ao controle da pressão arterial. Foram utilizadas as fichas A, a ata de reuniões do grupo de hipertensos e dados do levantamento do Sistema de Informação de Atenção Básica (SIAB) para obtenção dos dados das pessoas da amostra estudada, do bairro Vila Ipiranga, em Montes Claros (MG). Além disso, aplicou-se questionário para avaliar a influência do grupo no controle da pressão. Após análise dos dados, percebeu-se uma prevalência de mulheres no perfil dos participantes do grupo de hipertensos; uma idade média superior a 60 anos; mais da metade recorreriam à Unidade de Saúde em primeira instância em caso de doença; a ocupação predominante é aposentado/ pensionista e a maioria participa de grupo religioso. Quanto à renda familiar e à per capita, predominam as faixas de um a dois salários mínimos e menor que um salário mínimo, respectivamente. O grupo mostrou-se efetivo, já que todos os entrevistados relataram que ele contribuiu para o controle da pressão arterial, funcionando como importante instrumento no sentido de fornecer esclarecimentos acerca da doença, influenciar na mudança de hábitos de vida e conscientização quanto à importância de seguir o tratamento corretamente. Quando se faz uma avaliação longitudinal, selecionando os usuários que participaram três ou mais vezes, percebe-se que, dos 13, 10 (76,92%) evoluíram com diminuição dos níveis pressóricos e controle da PA, corroborando a influência positiva do grupo no controle da PA.

[Average working life of nurses graduating form the University of Sao Paulo at Ribeirao Preto, USP - Brazil]

This study aimed at measuring the average working time in health care of nurses graduating from the University of São Paulo at Ribeirão Preto College of Nursing, Brazil. This research includes 1,112 nurses who graduated from 1957 to 1990. It is a descriptive cross-sectional study. Data were obtained from March, 1992 to February, 1993. Statistical methods for survival data analysis were used. The average time was 18.12 years.

[Permanence of nurses in their profession]

The main cause for nursing shortage in the world is that nurses are withdrawing the profession. However few research has been carried out to prove this. This study investigates nurses' permanence in job and their motives for withdrawing it. Researchers tried to contact 1112 nurses who enrolled the profession after finishing the undergraduate nursing course at the University of São Paulo at Ribeirão Preto College of Nursing, Brazil, in the period from 1957 to 1990. They were not able to contact 95 nurses (8.54%) from the total. Therefore, 1017 (91.46%) were contacted by mail, telephone or interview to answer a questionnaire, 808 (72.66%) answered, 194 (17.45%) did not reply, 4 (0.36%) refused to answer and 11 (0.99%) died, generating the following data: 19 (2.35%) never worked, 661 (81.81%) are working in the profession, 102 (12.62%) worked and withdrew nursing, 26 (3.22%) retired. Considering this group, the analysis showed that the percentage who left the profession is small, nevertheless other studies are suggested in order to enable the comparison of these results. The motives for their permanence are their attachment to the profession, even though they say that their work is not recognized and they are badly paid. The reasons for withdrawing the profession are family and personal problems as well as constant changes in the schedule and general frustration. In sum, nurses love their profession and would like to continue working. Some of them are returning and asking for better conditions.

Post-discharge surveillance and infection rates in obstetric patients

OBJECTIVE

To study the impact of post-discharge surveillance on the detection of nosocomial surgical site infection (SSI) after cesarean section and vaginal delivery.

METHODS

During a 21-month period, all patients attending the obstetrics service in labor were recruited for a observational study on the incidence of SSI. Examinations to detect SSI were performed daily during the hospitalization period and up to 30 days after hospital discharge in an outpatient clinic supervised by the Infection Control Committee. The stratification of risk-factors and the criteria for the diagnosis of SSI were done in accordance with the methods described by the Centers for Disease Control and Prevention. The rates of surgical site infection detected during the hospitalization period were compared with those reported by the Centers for Disease Control and Prevention's National (United States) Nosocomial Infection Surveillance System (CDCNNIS) 'benchmarks'. The incidence of SSI detected by post-discharge outpatient surveillance was compared with that from in-hospital surveillance, for both cesarean section and vaginal delivery.

RESULTS

A total of 4463 deliveries were performed during the study period, 2431 (54.5%) by the vaginal route and 2032 (45.5%) by cesarean section. In-hospital surveillance was done on all patients. Post-discharge examinations were done on 951 (46.8%) of the 2032 cesarean section patients. The incidence of SSI in cesarean section detected by in-hospital surveillance was 1.6% (32 cases) and lower than the 3.6% mean rate reported by the CDCNNIS. When SSIs detected by post-discharge surveillance were included, the total number of SSI was 196 cases (9.6%), a value much higher than that for the SSI detected by in-hospital surveillance alone. Only 5 cases (0.21%) of SSI were detected among the 2431 vaginal deliveries.

CONCLUSIONS

The results of our study demonstrate that most of SSI following cesarean section were detected only after patient's discharge from the hospital and seems to indicate that failing to do follow-up evaluation of these patients could result in a substantial mis-calculation of the authentic SSIs rates. Therefore data on post-discharge surveillance should be included to realistically estimate the true rates of SSI in obstetric patients and to allow the implementation of measures to reduce post-partum infection.
