Parent Stress and Observed Parenting in a Parent-Child Interaction Task in a Predominantly Minority and Low-Income Sample.

High stress in parents may affect parenting and subsequent child socioemotional and behavioral development. Previous evidence suggests that highly stressed parents are more likely to engage in negative parenting, which is less structured and more punitive. However, the effects of life stress versus parent specific stress on parent-child interactions in early childhood has not been well studied, especially in minority and low-income samples. Thus, the current study assessed the relationship between perceived life stress, parenting-related stress, and observed parenting responses to young children during a structured, mildly challenging parent-child task. Predominantly minority and low-income parents and their children (2-5 years old; 54 dyads) completed the Perceived Stress Scale, the Parenting Stress Inventory, and participated in a structured 5-minute interaction task, the Toy-Wait Task (TWT), that was video-taped and coded by blind raters. The coding utilized a standardized system with good reliability assessing 1) Affect (parent and child positive and negative affect, shared positive affect), 2) Positive Parenting Behaviors (warmth, structured good involvement, listening/engagement), and 3) Negative Parenting Behaviors (reactivity, judgment, critical parenting). Significant associations were found between perceived life stress and parenting stress, (r (54) = 0.61, p<.01). Parents with higher perceived life stress scores showed more negative affect (r=0.291, p<.05) and lower involvement with the child (r=-0.367, p<.05), while parenting specific stress did not yield significant effects (p's > 0.05). Findings suggest that interventions that reduce stress in minority and low-income parents of young children may also improve parenting of young children with potential impact on decreasing child psychopathology risk.

Sugarcane productivity and economic viability in response to planting density.

Planting with higher density in sugarcane is one of the practices used to overcome low productivity. However, this planting material is equivalent to 25% of the total cost of production, being one of the main expenses for cultivation. In this sense, the present work aims to evaluate the productivity and economic viability of sugarcane as a function of planting density. The experiment was carried out at Usina Monte Alegre in the municipality of Mamanguape, Paraíba, Brazil, from March 2021 to January 2022 with the variety RB92579. Seven planting density were studied: T1: 7 gems m-1, T2: 10 gems m-1, T3: 12 gems m-1, T4: 11 gems m-1, T5: 15 gems m-1, T6: 17 gems m-1, T7: 24 gems m-1, in randomized blocks with four replications. Growth, productivity and economic viability were evaluated. The highest productivity of cane and sugar, 77.69 ton ha-1 and 10.390 ton ha-1, respectively, was with planting density of 17 and 24 gems-1. While the minimum productivity of cane (61.313 ton ha-1) and sugar (7.924 ton ha-1) was recorded at sowing density of 7 and 11 gems-1. However, cultivation density with 7 and 10 gems m-1 were the ones that provided the highest profitability around 50%, followed by density of 12, 15 and 17 gems m-1 with an average of 45% profit and 11 and 24 gems m-1 with the lowest proportion of profit on average 38%. The cultivation with 17 gems m-1 of cane provides in cane-plant, variety RB92579, greater productivity with a profit rate of 45%, being the most suitable.

REDISCOVER guidelines for borderline-resectable and locally advanced pancreatic cancer: management algorithm, unanswered questions, and future perspectives.

The REDISCOVER guidelines present 34 recommendations for the selection and perioperative care of borderline-resectable (BR-PDAC) and locally advanced ductal adenocarcinoma of the pancreas (LA-PDAC). These guidelines represent a significant shift from previous approaches, prioritizing tumor biology over anatomical features as the primary indication for resection. Condensed herein, they provide a practical management algorithm for clinical practice. However, the guidelines also highlight the need to redefine LA-PDAC to align with modern treatment strategies and to solve some contradictions within the current definition, such as grouping "difficult" and "impossible" to resect tumors together. Furthermore, the REDISCOVER guidelines highlight several areas requiring urgent research. These include the resection of the superior mesenteric artery, the management strategies for patients with LA-PDAC who are fit for surgery but unable to receive multi-agent neoadjuvant chemotherapy, the approach to patients with LA-PDAC who are fit for surgery but demonstrate high serum Ca 19.9 levels even after neoadjuvant treatment, and the optimal timing and number of chemotherapy cycles prior to surgery. Additionally, the role of primary chemoradiotherapy versus chemotherapy alone in LA-PDAC, the timing of surgical resection post-neoadjuvant/primary chemoradiotherapy, the efficacy of ablation therapies, and the management of oligometastasis in patients with LA-PDAC warrant investigation. Given the limited evidence for many issues, refining existing management strategies is imperative. The establishment of the REDISCOVER registry ( https://rediscover.unipi.it/ ) offers promise of a unified research platform to advance understanding and improve the management of BR-PDAC and LA-PDAC.

REDISCOVER International Guidelines on the Perioperative Care of Surgical Patients With Borderline-resectable and Locally Advanced Pancreatic Cancer.

OBJECTIVE: The REDISCOVER consensus conference aimed at developing and validating guidelines on the perioperative care of patients with borderline-resectable (BR-) and locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC). BACKGROUND: Coupled with improvements in chemotherapy and radiation, the contemporary approach to pancreatic surgery supports the resection of BR-PDAC and, to a lesser extent, LA-PDAC. Guidelines outlining the selection and perioperative care for these patients are lacking. METHODS: The Scottish Intercollegiate Guidelines Network (SIGN) methodology was used to develop the REDISCOVER guidelines and create recommendations. The Delphi approach was used to reach a consensus (agreement ≥80%) among experts. Recommendations were approved after a debate and vote among international experts in pancreatic surgery and pancreatic cancer management. A Validation Committee used the AGREE II-GRS tool to assess the methodological quality of the guidelines. Moreover, an independent multidisciplinary advisory group revised the statements to ensure adherence to nonsurgical guidelines. RESULTS: Overall, 34 recommendations were created targeting centralization, training, staging, patient selection for surgery, possibility of surgery in uncommon scenarios, timing of surgery, avoidance of vascular reconstruction, details of vascular resection/reconstruction, arterial divestment, frozen section histology of perivascular tissue, extent of lymphadenectomy, anticoagulation prophylaxis, and role of minimally invasive surgery. The level of evidence was however low for 29 of 34 clinical questions. Participants agreed that the most conducive means to promptly advance our understanding in this field is to establish an international registry addressing this patient population ( https://rediscover.unipi.it/ ). CONCLUSIONS: The REDISCOVER guidelines provide clinical recommendations pertaining to pancreatectomy with vascular resection for patients with BR-PDAC and LA-PDAC, and serve as the basis of a new international registry for this patient population.

Consumption of sugar-sweetened soft drinks and risk of metabolic syndrome and its components: results of the ELSA-Brasil study (2008-2010 and 2012-2014).

AIM: To estimate the association between consumption of sugar-sweetened soft drinks and unsweetened fruit juice with metabolic syndrome (MetS) and its components in participants of the Brazilian Longitudinal Adult Health Study (ELSA-Brasil) after 4 years of follow-up. METHODS: We used data from ELSA-Brasil cohort (N = 15,105). The sample consisted of 6,124 civil servants free of the MetS at baseline (35 to 74 years, both sexes). The consumption of sugar-sweetened soft drinks and unsweetened fruit juice was estimated by a food frequency questionnaire previously validated. The outcome was MetS and its components (Joint Interim Statement criteria). To test the association between beverage consumption at baseline (2008-2010) and MetS and its components at follow-up (2012-2014), we used Poisson regression models with robust variance adjusting for potential confounders. RESULTS: After 4-year follow-up, the higher consumption of sugar-sweetened soft drinks (≥ 1 serving/day = 250 mL/day) increased the relative risk of MetS (RR = 1.22; 95% CI 1.04-1.45), high fasting glucose (RR = 1.23; 95% CI 1.01-1.48), and high blood pressure (RR = 1.23; 95% CI 1.00-1.54). Moderate consumption of this beverage (0.4 to < 1 serving/day) increased the relative risk of high waist circumference (WC) (RR = 1.21; 95% CI 1.02-1.42). After adjustment for confounding variables, the consumption of unsweetened fruit juice was not associated with the MetS and its components. CONCLUSION: Higher sugar-sweetened soft drinks consumption was associated with a higher risk relative of MetS, high fasting glucose, and high blood pressure, while moderate consumption of this beverage increased the relative risk of high WC in Brazilian adults.

Behavioral Effects of Extracts and Compounds Isolated from Erythrina Velutina (Mulungu) in Rats

In many countries and also Brazil, the extracts or infusions of fresh plants are used to treat common infections or diseases, mainly in the countryside and among the indigenous people. The popular knowledge of the medicinal plants contributes a lot to the benefit of the human health, and directly could help for new discoveries of medicines. The antinociceptive effect is an important target for new active compounds to be searched, in part due to the increase in human life expectation, on the other hand for new cheaper compounds to the low income population, and finally, with new properties or less side effects. In the current work, extracts obtained from Erythrina velutina seeds, commonly used against snake bites, were tested for the capacity to neutralize the nociceptive effects induced by the hot plate test and anxiety behavior with combination of the open field and the elevated plus maze. Tested animals (rats) with different extracts of seed demonstrated analgesic effect with the animal on hot plate. The animals also increased wandering in the open field and even the numbers of entries and the time spent in the open arms of the elevated plus maze. That demonstrated that lesser anxiety levels allow longer and more frequent exploration periods of the open arms, suggesting that Erythrina velutina has strong anxiolytic properties compared to the control anxiolytic diazepam, it could serve as a new approach for the treatment anxiety.

Assessing intermittent saline inflows in urban water systems.

Urban water drainage systems' primary function is to transport sanitary or stormwater. The intrusion of saline waters has recognized detrimental effects. Especially in coastal areas, saline inflows can compromise performance by increasing the risk of untreated discharges, weakening the structural condition of concrete or metallic components, reducing the effectiveness of wastewater treatment processes and limiting the potential reuse for irrigation. Performance deterioration can be prevented by an early assessment of exposure to saline water, followed by timely actions to control its causes and consequences. The paper describes a procedure for diagnosing undue saline inflows. The procedure is based on the determination of saline inflow's magnitude, acceptance levels, and contribution to the system's performance. Contextual factors and performance indicators, and their reference values, are selected for the assessment. Options to address the problem are proposed, depending on the results. These options can relate to organizational, operational, and structural actions. Application to a case study allowed to validate the method and discuss the results. Here, saline volumes entering the system are quite relevant (almost 30%), posing problems regarding corrosion, treatment plant operation and significant concrete exposure to intermittent saline waters.

Association between race/color and incidence of hypertension in the ELSA-Brasil population: investigating the mediation of racial discrimination and socioeconomic position.

OBJECTIVE: To investigate the mediation effect of socioeconomic position and racial discrimination in the association between race/color and incidence of hypertension in 4-years follow up. METHODS: We included 8,370 participants of the Longitudinal Study of Adult Health (ELSA-Brasil). A latent variable was constructed to represent socioeconomic position (SEP). The perception of discrimination was measured through an adaptation of the Lifetime Major Events Scale; and hypertension was defined using standard criteria. We investigated Body Mass Index (BMI) due to its role in proximal risk for hypertension. To investigate the mediating role of SEP and racial discrimination, we used structural equation modeling. RESULTS: SEP had a direct and negative effect on HT incidence (HT incidence increased in worse SEP categories), while the effect of BMI on HT was direct and positive. We did not find significant direct effects of race/color and racial discrimination on HT. As for indirect effects, we observed associations between race/color and HT only through SEP mediation. CONCLUSION: According to our results, race/color is indirectly related to HT incidence, mediated by SEP. Racial discrimination was not a mediator in the relationship between race/color and HT in the follow-up period.

Ideal vascular health and cognitive performance in the Brazilian Longitudinal Study of Adult Health.

BACKGROUND AND PURPOSE: Most evidence for the association between ideal vascular health (IVH) and cognitive performance comes from high income countries. The aim was to investigate this association in the Brazilian Longitudinal Study of Adult Health. METHODS: Cognition was assessed using the word list, verbal fluency and trail making tests. The IVH score included ideal metrics for body mass index, smoking, physical activity, diet, blood pressure, fasting glucose and total cholesterol. Poor, intermediate and optimal health were characterized in those presenting 0-2, 3-4, 5-7 ideal metrics, respectively. To determine the association between IVH score and cognitive performance, linear regression models adjusted for age, sex, education, race, alcohol use, depression and thyroid function were used. RESULTS: In 12 271 participants, the mean age was 51.3 ± 8.9 years, 54% were women, 57% White and 53% had poor vascular health. Participants with intermediate (ß = 0.064, 95% confidence interval 0.033; 0.096) and optimal health (ß = 0.108, 95% confidence interval 0.052; 0.164) had better global cognitive Z-scores. In addition, interactions of IVH score with age, education and race were found, suggesting a better cognitive performance with higher IVH in older adults, Black/Brown participants and those with lower levels of education. CONCLUSION: Ideal vascular health was associated with better cognitive performance. Older, Black/Brown and low-educated participants had better cognition in the presence of higher IVH scores.

Association between dietary patterns and renal function in a cross-sectional study using baseline data from the ELSA-Brasil cohort.

Previous analyses of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) identified four main dietary patterns (DP). The aim of this study was to explore the association between the previously defined DP and renal function (RF). A cross-sectional study using the ELSA-Brasil baseline data was carried out. DP ("traditional", "fruits and vegetables", "bakery", and "low sugar/low fat), metabolic syndrome (MS) using the Joint Interim Statement criteria, microalbuminuria (MA), and glomerular filtration rate (eGFR) through the CKD-EPI equation were evaluated. Abnormal RF was defined as eGFR<60 mL·min-1·(1.73 m2)-1 and MA≥3.0 mg/dL. Factors associated with RF were determined and mediation analysis was performed to investigate the association between DP, MS, and RF. A total of 15,105 participants were recruited, with a mean age of 52±9 years; 8,134 participants (54%) were females. The mediation analysis identified indirect associations between "bakery" and "fruits and vegetables", and both were associated with decreased eGFR and albuminuria in both genders, compared with "traditional" and "low sugar/low fat" patterns in the general population. There was a direct association of the "bakery" pattern with MA in men (OR: 1.17, 95%CI: 1.92-1.48). The "fruits and vegetables" pattern also showed a direct association with reduced eGFR in women (OR: 1.65, 95%CI: 1.28-2.12), although there was no significance after adjustment. The "fruits and vegetables" and "bakery" DPs were associated with renal dysfunction. The only independent, direct association was between "bakery" DP and MA in men, raising concerns about DP and renal damage in men.

Association between cognitive performance and self-reported glaucoma in middle-aged and older adults: a cross-sectional analysis of ELSA-Brasil.

Recent evidence suggests that glaucoma and Alzheimer's disease are neurodegenerative diseases sharing common pathophysiological and etiological features, although findings are inconclusive. We sought to investigate whether self-reported glaucoma patients without dementia present poorer cognitive performance, an issue that has been less investigated. We employed cross-sectional data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) and included participants ≥50 years of age without a known diagnosis of dementia and a self-reported glaucoma diagnosis. We excluded those with previous stroke, other eye conditions, and using drugs that could impair cognition. We evaluated cognition using delayed word recall, phonemic verbal fluency, and trail making (version B) tests. We used multinomial linear regression models to investigate associations between self-reported glaucoma with cognition, adjusted by several sociodemographic and clinical variables. Out of 4,331 participants, 139 reported glaucoma. Fully-adjusted models showed that self-reported glaucoma patients presented poorer performance in the verbal fluency test (ß=-0.39, 95%CI=-0.64 to -0.14, P=0.002), but not in the other cognitive assessments. Thus, our results support the hypothesis that self-reported glaucoma is associated with poor cognitive performance; however, longitudinal data are necessary to corroborate our findings.

Biopsychosocial factors associated with a current depressive episode in diabetes: the ELSA-Brasil study.

AIMS: Depression is more prevalent in people with diabetes, and is associated with worse diabetes outcomes. Depression in diabetes is more treatment resistant, and as underlying mechanisms are unknown, development of more effective treatment strategies is complicated. A biopsychosocial model may improve our understanding of the pathophysiology, and therewith help improving treatment options. METHODS: Diabetes was diagnosed according to American Diabetes Association (ADA) criteria and a current depressive episode according to the International Classification of Diseases (ICD-10), based on the Clinical Interview Schedule Revised (CIS-R). From the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), we included 455 participants without diabetes with a current depressive episode and 10 900 without either diabetes or a current depressive episode. Furthermore, 2183 participants had diabetes alone and 106 had both diabetes and a current depressive episode. Variable selection was based on their relationship with depression and/or diabetes. Multinomial multivariate logistic regression was used to determine how the models differed between participants with and without diabetes. RESULTS: A current depressive episode in diabetes was related to being older and female, having poorer education, financial problems, experiencing discrimination at work, home and school, higher waist circumference, albumin to creatinine ratio and insulin resistance, and the presence of hypertension and cardiovascular disease. In non-diabetes, a current depressive disorder was related to being female, not being black, low income, psychological and social factors, non-current alcohol use, lower HDL cholesterol, higher insulin resistance and the presence of cardiovascular disease. CONCLUSIONS: A current depressive episode in the presence compared with the absence of diabetes was related more to biological than to psychosocial factors.

Adherence to the Dietary Approaches to Stop Hypertension (DASH) and hypertension risk: results of the Longitudinal Study of Adult Health (ELSA-Brasil).

We investigated whether high adherence to the Dietary Approaches to Stop Hypertension (DASH) diet was independently associated with lower risk of incident hypertension. Participants included 5632 adults, without hypertension at the baseline (2008-2010) of the Longitudinal Study of Adult Health, who took part in the second follow-up visit (2012-2014). Adherence to the DASH diet was estimated at baseline using a score based on eight food items (final scores from 8 to 40 points) and was categorised as high adherence (≥30 points, or ≥75 %) and low adherence (<75 %; reference). Hypertension was defined as systolic blood pressure (BP) ≥140 mmHg or diastolic BP ≥90 mmHg, or use of antihypertensive drugs. The association between adherence to the DASH diet and the risk of incident hypertension was estimated using Cox regression models adjusted by covariates. In total, 780 new cases of hypertension (13·8 %) were identified in about 3·8-year follow-up. Participants with high adherence to the DASH diet had 26 % lower risk of hypertension (hazard ratio (HR) 0·74; 95 % CI 0·57, 0·95) after adjustment for socio-demographic characteristics, health-related behaviours, diabetes and family history of hypertension. The HR reduced to 0·81 (95 % CI 0·63, 1·04) and was of borderline statistical significance after adjustment for BMI, suggesting that lower body weight explains about 10 % of the association between high adherence to the DASH diet and hypertension risk reduction. The results indicate that high adherence to the DASH diet lowered the risk of hypertension by one-fourth over a relatively short follow-up period.

The "fruits and vegetables" and "bakery" DPs were associated with renal dysfunction. The only independent, direct association was between "bakery" DP and MA in men, raising concerns about DP and renal damage in men.

Association between ideal cardiovascular health and depression incidence: a longitudinal analysis of ELSA-Brasil.

OBJECTIVE: We investigated whether ideal cardiovascular health (ICH), a metric proposed by the American Heart Association, predicts depression development. METHODS: Cohort analysis from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Adults with no current depression and other common mental disorders, cardiovascular diseases, and antidepressant drug use at baseline had their ICH (composite score of smoking, dietary habits, body mass index, blood pressure, fasting glucose, cholesterol, and physical activity) assessed and classified into poor, intermediate, and optimal. Depression was assessed using the Clinical Interview Schedule-Revised (CIS-R). Poisson regression models, adjusted for sociodemographic factors and alcohol consumption, were employed. Stratified analyses were performed for age and sex. RESULTS: We included 9214 participants (mean age 52 ± 9 years, 48.6% women). Overall depression incidence at 3.8-year follow-up was 1.5%. Intermediate and poor ICH significantly increased the risk rate (RR) of developing depression (2.48 [95%CI 1.06-5.78] and 3 [1.28-7.03], respectively) at a 3.8-year follow-up. Higher ICH scores decreased the rate of depression development (RR = 0.84 [0.73-0.96] per metric). Stratified analyses were significant for women and adults < 55 years old. CONCLUSIONS: Poor cardiovascular health tripled depression risk at follow-up in otherwise healthy adults. Ameliorating cardiovascular health might decrease depression risk development.

Nasosinusal myiasis in elderly patient with mucocutaneous leishmaniosis.

BACKGROUND: Myiasis is a condition in which flies are attracted to infected and/or necrotic tissues and deposit eggs that hatch into larvae. It may bring serious functional and aesthetic sequelae when involves nasal and parasinusal cavities; however, there is a lack of such reports in the literature. METHODS: We present and briefly discuss herein the clinical and surgical management of nasosinusal myiasis in an elderly patient previously affected by mucocutaneous leishmaniosis. RESULTS: Facial computed tomography was used to confirm the nasosinusal involvement. Next, osteotomies were performed, followed by the mechanical removal of larvae, bilateral sinusectomy and pharmacological therapy. CONCLUSION: A complicated case of nasosinusal myiasis was surgically managed, resulting in a good prognosis for the patient.

Meta-analysis of an artery-first approach versus standard pancreatoduodenectomy on perioperative outcomes and survival.

BACKGROUND: The aim of this systematic review and meta-analysis was to evaluate perioperative outcomes and survival in patients undergoing an artery-first approach to pancreatoduodenectomy in comparison with those having standard pancreatoduodenectomy. METHODS: A systematic search of PubMed, MEDLINE, Embase and the Cochrane Database of Systematic Reviews was performed in accordance with PRISMA guidelines. Comparative studies including patients who underwent artery-first pancreatoduodenectomy and standard pancreatoduodenectomy were analysed. RESULTS: Seventeen studies were included in the final analysis. There were 16 retrospective cohort or case-control studies and one RCT. A total of 1472 patients were included in the meta-analysis, of whom 771 underwent artery-first pancreatoduodenectomy and 701 had standard pancreatoduodenectomy. Intraoperative blood loss (mean difference -389 ml; P < 0·001) and the proportion of patients requiring intraoperative transfusion (10·6 per cent (54 of 508) versus 40·1 per cent (186 of 464); P < 0·001) were significantly lower in the artery-first group. Although rates of perioperative mortality were comparable between the two groups, perioperative morbidity (35·5 per cent (263 of 741) versus 44·3 per cent (277 of 625); P = 0·002), and the incidence of grade B/C pancreatic fistula (7·4 per cent (26 of 353) versus 12·8 per cent (42 of 327); P = 0·031) were significantly lower in the artery-first group. The R0 resection rate (75·8 per cent (269 of 355) versus 67·0 per cent (280 of 418); P < 0·001) and overall survival (hazard ratio 0·72, 95 per cent c.i. 0·60 to 0·87; P < 0·001) were significantly higher in the artery-first group. CONCLUSION: The artery-first approach to pancreatoduodenectomy may be associated with improved perioperative outcomes and survival.
