RESUMO

Inflammation is an adaptive response that involves activation, and recruitment of cells of innate and adaptive immune cells for restoring homeostasis. To safeguard the host from the threat of inflammatory agents, microbial invasion, or damage, the immune system activates the transcription factor NF-κB and produces cytokines such as TNF-α, IL- 6, IL-1ß, and α. Sirtuin 1 (SIRT1) controls the increased amounts of proinflammatory cytokines, which in turn controls inflammation. Three phytoconstituents resveratrol (RES), pterostilbene (PTE), and curcumin (CUR) which are SIRT1- activators and that have marked anti-inflammatory effects (in-vivo), were chosen for the current study. These compounds were compared for their anti-inflammatory potential by in-silico docking studies for IL-6, TNF-α, NF-κB, and SIRT1 and in-vitro THP-1 cell line studies for IL-6, TNF-α. PTE was found to be more effective than RES and CUR in lowering the concentrations of IL-6 and TNF-α in THP-1 cell line studies, and it also showed a favorable docking profile with cytokines and SIRT1. Thus, PTE appears to be a better choice for further research and development as a drug or functional food supplement with the ability to reduce inflammation in metabolic disorders.

RESUMO

Cafeteria diet (CD) model for in-vivo studies mimics the western diet having imbalanced nutritional value, high caloric-density and palatability. Uncontrolled eating leads to the development of childhood obesity, poor self-esteem and depression due to its effects on brain development. Herbal supplements are novel inclusion in the management of obesity and mental well-being. Pterostilbene (PTE) found in blueberries and Pterocarpus marsupium heartwood, is known to prevent obesity in invivo models. Adolescent Swiss albino male mice were fed on CD for 70 days and the development of obesity was assessed by gain in body weight, abdominal circumference. Forced swim and tail suspension test confirmed depression in CD fed mice. Obesity induced depressed (OID) mice were treated with PTE (10, 20, 40 mg/kg), standard antiobesity drug cetilistat (10 mg/kg), antidepressant fluoxetine (10 mg/kg) for 28 days. Post treatment, PTE-treated mice showed reduction in BW and depression-like behavior analysed using paradigms such as sucrose preference, open field, marble burying, and resident intruder test in comparison to the CD group. Insulin resistance, lipid profile, antioxidant enzyme, inflammatory cytokines (NF-κB, IL-6, TNF α) and cortisol levels were mitigated by PTE. It also restored normal cellular architecture of the brain and adipose tissue and increased the Silent mating type information regulation 2 homolog1 (SIRT1), leptin and ghrelin receptors gene expression in the brain. Thus, it can be concluded that PTE might have inhibited OID like behavior in mice via inhibition of IR, modulating neuroinflammation and hypothalamic-pituitary-adrenal axis dysfunction and upregulating SIRT1 mediated leptin-ghrelin signaling.

RESUMO

Despite the role of calcium and vitamin D in osteoporosis and heart disease, little research has examined changes in the intake of calcium and vitamin D among individuals with these conditions over time. Using data from the 2004 and 2015 Canadian Community Health Surveys, we investigated changes in dietary and supplemental intake of calcium and vitamin D among Canadian older adults aged ≥ 50 years, both with and without heart disease and/or osteoporosis, between 2004 and 2015. Notable declines in dietary calcium intake occurred, particularly among non-supplement users. Surprisingly, individuals with osteoporosis and heart disease, who are at higher nutritional risk, were less likely to use calcium supplements in 2015 compared to 2004. Among calcium supplement users, those with osteoporosis or both conditions experienced significant reductions in their usual calcium intake in 2015, with an increased proportion failing to meet recommended intake levels. Conversely, vitamin D supplement users experienced a substantial rise in vitamin D intake in 2015. In 2015, only a small proportion of supplement users did not meet the recommended vitamin D intake levels. These findings underscore the importance of public health initiatives to facilitate safe increases in calcium and vitamin D intake for older adults, particularly those with heart disease and osteoporosis.

RESUMO

BACKGROUND: Pubertal delays in children with cystic fibrosis (CF) have historically been common. It is unclear to what degree puberty is affected in the new era of CF care or the role of early nutritional status. We hypothesized that more favorable early growth trajectories are associated with improved pubertal growth outcomes. METHODS: We used data from the United States CF Foundation Patient Registry to analyze associations between early weight-for-length/body mass index (WFL-BMI) growth trajectories and pubertal outcomes, using peak height velocity (PHV) and age at PHV (APHV) as proxy measures for puberty in addition to adult height (defined as height at age 18 years). Our analysis consisted of shape invariant mixed modeling and multivariable linear regression. RESULTS: Our sample consisted of 9,186 people with CF aged 18 to 21 years between 2010-2019. APHV was earliest and PHV/adult height were highest in those with WFL-BMI always >50th percentile from 0-6 years. However, there was no difference after adjusting for key covariates. Receiving CF transmembrane conductance regulator (CFTR) modulator therapy in childhood was associated with being taller at 18 years, by 0.92 cm in males (p=0.048) and 1.02 cm in females (p=0.010) in adjusted models. Higher height z-score at 2 years was associated with improved APHV and PHV for males and improved adult height for both males and females (p<0.001) in adjusted models. CONCLUSIONS: Early height, but not early WFL-BMI trajectories, may be associated with pubertal growth outcomes. CFTR modulator therapy shows the potential to improve pubertal growth outcomes, but further research is necessary.

RESUMO

One of the most serious mental health comorbidities associated with diabetes mellitus is depression. The occurrence is almost double in type 2 diabetes mellitus (T2DM) compared with the general population. Pterostilbene (PTE), a dimethylated analog of resveratrol, has been reported for significant neuroprotective, anti-inflammatory, hypolipidemic, hypoglycaemic and antioxidant effects. However, its effect on diabetes-induced depression-like behavior (DID) has not been studied. The current study aimed at studying the effects of PTE on depressive-like behavior in male Wistar rats with T2DM. It was induced by single dose administration of nicotinamide (NA) and streptozotocin (STZ). On day 21, forced swim test (FST) was conducted for the confirmation of DID. Rats demonstrating depressive-like behavior were treated with PTE (10, 20 and 40 mg/kg), metformin (MET; 500 mg/kg) and fluoxetine (FLX; 10 mg/kg) for 28 days, orally. At the end of the treatment, behavioral assessment for depression, blood glucose (BG) and lipid profile, oxidative stress markers, gene expression of Sirtuin 1 (SIRT1) and histopathological parameters were investigated. PTE significantly reduced weight loss and mitigated depressive-like behavior paradigms such as sucrose preference test (SPT), resident intruder test (RIT) and open field test (OFT). It significantly restored BG, lipid and liver profile, creatinine and antioxidant level. It Improved glucose tolerance, insulin resistance (IR) and reduced cortisol level as well as inflammatory markers. It showed improved morphology of the pancreas, brain, liver and kidney. Gene expression studies revealed that, PTE significantly increased SIRT1 expression. PTE by its virtue to maintain BG, reduced IR, amelioration of the HPA axis, anti-inflammatory, antioxidant activity and improvement of SIRT1 gene expression proved to be effective in the treatment of DID-like behavior in rats.

RESUMO

Nonalcoholic fatty liver disease (NAFLD) is the most common pediatric liver disease in the developed world, with primary care providers caring for many at-risk children. The prevalence of NAFLD varies widely by race and ethnicity. OBJECTIVE: To explore racial differences in screening and referral patterns for NAFLD among a high-risk pediatric population. METHODS: This retrospective cohort study studied primary care patients at Children's of Alabama aged 5-17 years with BMI ≥ 85th percentile from 2008 to 2018. The main outcomes of interest were screening for NAFLD with alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and referral to Hepatology, Endocrinology, or Weight Management clinics. RESULTS: Of 666 children with BMI ≥ 85th percentile, 65% were screened at least once for NAFLD during the designated study period. Liver enzyme screening was performed in 54% of Hispanic Whites, 50% of non-Hispanic Whites, and 74% of African Americans (p-value < 0.001). African American patients had the lowest rate of abnormal liver enzymes (defined as ALT and/or AST > 1 × upper limit of normal). Among all patients with abnormal liver enzymes, 87% of non-Hispanic Whites, 92% of Hispanic Whites, and 17% of African Americans were referred (p-value < 0.0001). CONCLUSIONS: Significant differences exist in NAFLD screening and referral practices by race/ethnicity. African Americans were far less likely to be referred for abnormal screening labs than their counterparts of other races. Awareness of these differences may allow for more intentional efforts to standardize practices, ensuring all patients receive care according to established guidelines.

RESUMO

Aldehyde oxidase (AO) has garnered curiosity as a non-CYP metabolizing enzyme in drug development due to unexpected consequences such as toxic metabolite generation and high metabolic clearance resulting in the clinical failure of new drugs. Therefore, poor AO mediated clearance prediction in preclinical nonhuman species remains a significant obstacle in developing novel drugs. Various isoforms of AO, such as AOX1, AOX3, AOX3L1, and AOX4 exist across species, and different AO activity among humans influences the AO mediated drug metabolism. Therefore, carefully considering the unique challenges is essential in developing successful AO substrate drugs. The in vitro to in vivo extrapolation underpredicts AO mediated drug clearance due to the lack of reliable representative animal models, substrate-specific activity, and the discrepancy between absolute concentration and activity. An in vitro tool to extrapolate in vivo clearance using a yard-stick approach is provided to address the underprediction of AO mediated drug clearance. This approach uses a range of well-known AO drug substrates as calibrators for qualitative scaling new drugs into low, medium, or high clearance category drugs. So far, in vivo investigations on chimeric mice with humanized livers (humanized mice) have predicted AO mediated metabolism to the best extent. This review addresses the critical aspects of the drug discovery stage for AO metabolism studies, challenges faced in drug development, approaches to tackle AO mediated drug clearance's underprediction, and strategies to decrease the AO metabolism of drugs.

RESUMO

Background: There is no oncologic basis for the extirpation of the submandibular gland (SMG) in early oral squamous cell carcinomas (OSCC) unless the SMG is truly infiltrated by the tumor. The study aimed at assessing the true involvement of SMG in OSCC and to determine whether the gland extirpation in all cases is justified. Methods: This study prospectively evaluated the pathological involvement of SMG by OSCC in 281 patients, who were diagnosed with OSCC and underwent wide local excision of the primary tumor with simultaneous neck dissection. Results: Among 281 patients, 29 (10%) cases underwent bilateral neck dissection. A total of 310 SMG were evaluated. Involvement of SMG was seen in 5 (1.6%) cases. SMG metastases from Level Ib were seen in 3 (0.9%) of cases, whereas 0.6% showed direct SMG infiltration from the primary tumor. The advanced floor of mouth and lower alveolus cases had a higher tendency to infiltrate SMG. In none of the cases, bilateral or contralateral SMG was involved. Conclusion: The findings of this study show that the extirpation of SMG in all cases is truly irrational. Preserving the SMG is justified in early OSCC with no nodal metastasis. However, SMG preservation is case dependent and is an individual preference. Further studies are required to assess the locoregional control rate and salivary flow rate in postradiotherapy cases where SMG is preserved.

RESUMO

BACKGROUND: The location and time of snack consumption may influence the composition, nutrient content and portion sizes of snacks. In this study, we aimed to determine and compare the time, location and frequency of snack consumption among different age groups of Canadians. METHODS: Nationally representative dietary data from the 2015 Canadian Community Health Survey (CCHS) were used (19,677 participants aged ≥2 years). Dietary data were obtained using 24-h dietary recalls. Participants were categorized according to the frequency of snack consumption (1 time, 2-3 times, ≥4 times). The snack consumption over 24 h was divided into four time periods: before 10 am, 10 am to 3 pm, 3 pm to 8 pm and 8 pm to 12 am. Meal and snack location was categorized as at home; someone else's home; restaurants; and other. RESULTS: Snacking 2-3 times per day was the most common reported frequency (53.0%). Snacking at home (73.0%) was more prevalent than snacking away from home (27.0%). The most frequently reported time for snacking among Canadians was 3 pm to 8 pm (36.3%), and the least frequently reported time was before 10 am (8.1%). Snacking contributed to a high proportion of Milk and Alternatives (23.7%) and Vegetables and Fruit (23.4%) food groups and lesser proportions of Grain Products (15.4%) and Meat & Alternatives (9.4%) food groups among Canadians. CONCLUSIONS: Home is the main location, 3 pm to 8 pm is the main time, and 2-3 times per day is the most common reported frequency for snacking. A full understanding of snacking behaviors is needed in order to develop targeted strategies to improve the quality of snack food choices.

RESUMO

The improper disposal and informal processing of e-waste have raised serious concerns for the environment and human health worldwide. A variety of legislative frameworks have been implemented to regulate e-waste management and upcycling in order to prevent environmental pollution and adopt resource reuse. Current e-waste legislation in different countries mostly include restrictions on e-waste import/export, regulations for recycling specific categories of e-waste, and Extended Producer Responsibility (EPR). This article serves as a comprehensive commentary to weigh the advantages and drawbacks of the different e-waste legislation enforced around the world. Though each country's e-waste legislation is enframed to address the country-specific problems, the legislation is mostly not holistic, leading to different management issues. A variety of e-waste management issues prevalent in most countries (with e-waste specific legislation) have been listed and categorized for better understanding of the status quo. Further, the article proposes a generic e-waste management model catering to requirements of countries around the world. The implementation of such a model for Europe, China, India, Japan, South Korea, Taiwan, and Australia has been illustrated to show that the model can suit both developed and developing countries with contrasting e-waste management issues. The challenges that would arise in implementing an effective legislation and mechanisms for overcoming these challenges have also been discussed. To conclude, the role of governing bodies in tackling the future e-waste problems has been highlighted. In total, the article promotes scaling up the feasibility and efficacy of the implementation of e-waste policies across the globe in the coming years.

RESUMO

BACKGROUND: In light of the publications (2008-2014) linking calcium intake, mainly from supplements, to the elevated risk of cardiovascular events, there is a need to determine if there have been any changes in usual intakes of calcium among Canadians. OBJECTIVE: We aimed to examine changes in dietary and total usual intake of calcium among Canadians aged ≥1 y over the period 2004-2015. METHODS: We used nutrition data from 2 nationally representative surveys conducted in 2004 and 2015 (CCHS 2004 Cycle 2.2 and CCHS-Nutrition 2015). This study included all the Canadians across 10 provinces, and the analyses were performed across different age/sex groups. We used the National Cancer Institute (NCI) method to estimate the usual intake of calcium and the prevalence of calcium inadequacy. Multiple logistic regression was performed to assess the relation between supplement uses and sociodemographic variables. RESULTS: From 2004 to 2015, the usual intake of calcium from food sources significantly decreased in calcium supplement nonusers (from 872 ± 18.2 mg/d to 754 ± 18.0 mg/d), but not in calcium supplement users. The contribution of calcium from the Milk and alternatives food group significantly decreased by 7.5% and 6.1% in calcium supplement users and nonusers, respectively. The prevalence of calcium supplement use significantly decreased from 2004 to 2015 in the Canadian population, from 27.5% to 22.0%. During this time, the percentage contribution of calcium from supplemental sources significantly decreased among Canadians, especially women. The prevalence of calcium inadequacy increased from 58.0% to 68.0% in supplement nonusers; however, among users of calcium supplements, the prevalence of calcium inadequacy remained at ∼31%. CONCLUSIONS: Calcium intake from both food and supplemental sources decreased in the Canadian population over an 11-y period, which must be addressed by policy-makers in their efforts to decrease the high prevalence of calcium inadequacy.

RESUMO

BACKGROUND: Evidence is lacking to determine whether there have been any changes in dietary or total usual intakes of vitamin D among Canadians, in the light of recent evidence of beneficial health effects beyond bone. OBJECTIVE: We aimed to examine trends in dietary and total usual intake of vitamin D among Canadians aged ≥1 y. METHODS: This study used nationally representative nutrition data from the Canadian Community Health Survey Cycle 2.2 (CCHS 2004) and CCHS Nutrition in 2015. Dietary intake data were collected with use of two 24-h dietary recalls and dietary supplement use was determined by questionnaire. The National Cancer Institute method was used to estimate the usual intake of vitamin D as well as the prevalence of vitamin D inadequacy among Canadians aged ≥1 y. RESULTS: From 2004 to 2015, the usual intake of vitamin D from food significantly decreased (P < 0.05) by 1 µg/d only in vitamin D supplement nonusers. The contribution of Milk and Alternatives food group (i.e., fluid milk, fortified soy beverages, powdered milk, and other milk alternatives) to dietary vitamin D intake significantly decreased (P < 0.05) in both supplement users (by 7.1%) and nonusers (by 5.8%). Prevalence of vitamin D supplement use and percentage contribution of vitamin D from supplemental sources significantly increased (P < 0.05) by 5.0% and 14.9%, respectively, from 2004 to 2015. Total usual intake of vitamin D (food + supplement) significantly increased (P < 0.05) from 15.1 ± 0.3 µg/d in 2004 to 31.5 ± 1.8 µg/d in 2015 in vitamin D supplement users. In contrast to vitamin D supplement nonusers, the prevalence of vitamin D inadequacy significantly decreased (P < 0.05) from 20.6% to 14.1% among users of vitamin D supplements. CONCLUSIONS: The prevalence of vitamin D supplement use and the percentage contribution of vitamin D from supplemental sources has increased in the Canadian population over an 11-y period.

RESUMO

Mandibular resections have a dramatic effect on oral cavity functions. Ablative surgical defects are complex which are better reconstructed with free flaps. In developing countries like India, where majority of patients come from low socioeconomic status, pectoralis major myocutaneous flap is the most preferred reconstructive option. A retrospective questionnaire study was carried out to assess the mastication in patients with mandibulectomy followed by pectoralis major myocutaneous flap reconstruction. At the end of the study, it was observed that 86.6% of the patients had a good performance despite the lack of bony reconstruction. Thus, pectoralis major myocutaneous flap still stands strong in reconstructing large oral cavity defects.

RESUMO

The snacking prevalence, frequency of daily snack consumption, and the contribution of snacks to daily energy intake have substantially increased globally. The aim of this study was to examine the patterns of snack consumption among a representative sample of Canadians aged 2 and older. Nationally representative dietary data from the Canadian Community Health Survey (CCHS) conducted in 2015 (n = 19,677 participants aged ≥2 years) were used to describe snacking patterns. In all, 80.4% of Canadians reported consuming at least one snack per day, which varied between different age groups from 77.0% (≥55 years) to 96.4% (2-5 years). About 37% of snack consumers reported only one snack episode per day but nearly 10% reported four or more episodes of snacking. Snacking contributed to nearly 23% of total daily energy intake in Canadians, which was highest among younger children (27%) and lowest among older adults (20.8%). There were no significant differences in obesity measures comparing snack consumers and non-consumers in children and adults. Snacking considerably contributes to total nutrient and energy intake of Canadians. Promoting nutrient-dense snacks provides an opportunity to improve overall diet quality.

RESUMO

In recent years, ready-to-eat cereal (RTEC) has become a common breakfast option in Canada and worldwide. This study used the nationally representative cross-sectional data from the Canadian Community Health Survey (CCHS) 2015-Nutrition to determine patterns of RTEC consumption in Canada and the contribution to nutrient intake among Canadians who were ≥2 years, of whom 22 ± 0.6% consumed RTEC on any given day. The prevalence of RTEC consumption was highest in children aged two to 12 years (37.6 ± 1.2%), followed by adolescents aged 13 to 18 years (28.8 ± 1.4%), and then by adults ≥19 years (18.9 ± 0.6%). RTEC consumers had higher intakes of "nutrients to encourage" compared to the RTEC non-consumers. More than 15% of the daily intake of some nutrients, such as folic acid, iron, thiamin, and vitamin B6, were contributed by RTEC. It was noted that nearly 66% of milk consumption was co-consumed with RTEC among RTEC consumers. The nutrient density of the diet, as defined by Nutrient-Rich Food Index (NRF 9.3), was significantly higher among RTEC consumers compared to non-consumers. RTEC consumption was not associated with overweight/obesity. RTEC consumption considerably contributed to the intake of some key nutrients among all age groups in Canada.

RESUMO

The current study utilizes a nationally representative nutrition survey data (Canadian Community Health Survey 2015, nutrition component, n = 20,487) in order to evaluate patterns of yogurt consumption among Canadians. Overall, 20% of Canadians have reportedly consumed yogurt on a given day in 2015. Higher prevalence of yogurt consumption was noted among children aged 2-5 years old (47%) when compared to adults aged 19-54 years (18%). When the prevalence of yogurt consumption at the regional level in Canada was assessed, Quebec had the most consumers of yogurt (25%) compared to other regions, namely the Atlantic (19%), Ontario (18%), Prairies (19%) and British Columbia (20%). Yogurt consumers reported consuming higher daily intakes of several key nutrients including carbohydrates, fibre, riboflavin, vitamin C, folate, vitamin D, potassium, iron, magnesium, and calcium when compared to yogurt non-consumers. Additionally, the diet quality, measured using NRF 9.3 scoring method, was higher among yogurt consumers compared to non-consumers. Nearly 36% of Canadians who meet the dietary guidelines for milk and alternative servings from the Food Guide Canada (2007) reported consuming yogurt.

RESUMO

Inflammatory myofibroblastic tumor is an uncommon soft tissue neoplasm of uncertain biologic behavior, and rarely reported in the stomach. An eighteen-year-old male presented with a mass in the epigastrium of three-month duration. Clinical and radiological examination suggested a gastrointestinal stromal tumor or a leiomyoma in the lesser curvature of the stomach. On the basis of histomorphological features and immunohistochemical analysis the diagnosis of inflammatory myofibroblastic tumor in the lesser curvature of the stomach was made. Inflammatory myofibroblastic tumor should be considered in the differential diagnosis of soft tissue tumors of the stomach.

RESUMO

Sri Lanka is experiencing a rapid increase in the number of people with diabetes mellitus (DM) due to population growth and aging. Physician shortages, outdated technology, and insufficient health education have contributed to the difficulties associated with managing the burden of disease. New models of chronic disease management are needed to address the increasing prevalence of DM. Medical students, business students, and faculty members from the University of Michigan partnered with the Grace Girls' Home, Trincomalee General Hospital, and Selvanayakapuram Central Hospital to identify and train diabetes-focused medical assistants (MAs) to collect and enter patient data and educate patients about their disease. Return visits to these MAs were encouraged so that patient progress and disease progression could be tracked longitudinally. Data entry was conducted through a cloud-based mechanism, facilitating patient management and descriptive characterization of the population. We implemented this pilot program in June 2016 in coordination with Trincomalee General Hospital and Selvanayakapuram Central Hospital. Over a 12-month period, 93 patients were systematically assessed by the medical assistants. All patients received education and were provided materials after the visit to better inform them about the importance of controlling their disease. Fifteen percent (14/93) of patients returned for follow-up consultation. Trained MAs have the potential to provide support to physicians working in congested health systems in low-resource settings. Public investment in training programs for MAs and greater acceptance by physicians and patients will be essential for handling the growing burden associated with chronic illnesses like DM. Trained MAs may also play a role in improved patient education and awareness regarding diabetes self-management.
