ABSTRACT

Background and Objective: The cancer-immunity cycle (CIC) is defined as a series of progressive events that cause an anticancer immune response leading to the killing of the cancer cell. The concept of CIC has important guiding significance for the clinical and basic tumor immunotherapy research. As one of the methods of traditional Chinese medicine (TCM), Chinese herbal medicine (CHM) has shown unique advantages in multitarget and multipathway immune regulation. However, the tumor immune circulation targeted by CHM is generally unclear at present. To provide reference for future clinical and basic research, we systematically reviewed the existing literature on CHM (including CHM monomers, CHM compounds, and CHM patent medicines) and the mechanisms related to its efficacy. Methods: We searched the PubMed and China National Knowledge Infrastructure (CNKI) databases for relevant Chinese-language and English-language literature published from January 1988 to October 2022. The literature was screened manually at three levels: title, abstract, and full text, to identify articles related to CHM and their mechanism of regulating tumor immunity. Key Content and Findings: By further classifying the CIC, it was confirmed that CHM can regulate the activation of dendritic cells (DCs) and macrophages and promote the presentation of tumor antigens. Meanwhile, CHM can also reverse tumor-immune escape by enhancing T-cell proliferation and infiltration. In addition, CHM can also enhance the antitumor ability of the body by regulating the killing process of tumor cells. Conclusions: The theory of a CIC is of guiding significance to regulating tumor immunity via CHM.

ABSTRACT

Glycated hemoglobin (HbA1c) is used to assess glycemic control in Type 1 diabetes (DM1) patients. Apolipoproteins play an essential role in DM1 pathophysiology and may be associated with complications and HbA1c. This cross-sectional observational study of 81 children and adolescents of both sexes diagnosed with DM1 investigated the relationship between body fat distribution and lean mass with HbA1C and apolipoprotein values, analyzing biochemical and body composition measurements. A Shapiro-Wilk test with Lilliefors correction, a non-parametric Mann-Whitney test, and others were used with a significance level of 5%. The sample had a diagnosis time of 4.32 years and high blood glucose levels (mean 178.19 mg/dL) and HbA1c (mean 8.57%). Subjects also had a moderate level of adiposity, as indicated by arm and thigh fat areas. The study also found significant differences in the distribution of patients concerning levels of apolipoproteins A and B, with a smaller proportion of patients having undesirable levels. Finally, the study found a significant difference in the distribution of patients with estimated cardiovascular risk based on the ApoB/ApoA-I ratio. Conclusively, visceral fat in children and adolescents with DM1 may increase the risk of DM1 long-term complications owing to its association with elevated HbA1C and apolipoprotein values.

ABSTRACT

Introduction: The lipid accumulation product (LAP) and visceral adipose index (VAI) are clinical markers of visceral obesity and were proposed as simple tools to estimate cardiovascular risk and mortality. The objective of this study was to analyze the accuracy of the VAI and LAP for high cardiovascular risk patients. Methods: A cross-sectional observational study of accuracy was carried out in 193 patients of both sexes. In addition to the variables VAI and LAP, presence of comorbidities, education, level of physical activity and anthropometric data were obtained. Cardiovascular risk was determined by the Framingham score. Results: No significant difference was observed in the sample in gender distribution (44.6% women; 55.4% men), 24.4% had low cardiovascular risk, 48.7% intermediate risk and 26.9% high cardiovascular risk. Linear regression analysis showed that VAI and LAP explain, respectively, only 2.4% and 5.2% of the variation in cardiovascular risk expressed by the Framingham score. The analysis of areas under the curve (AUC) for receiver operating characteristic (ROC) indicated a significant effect only of LAP to diagnose individuals with high cardiovascular risk, but with low sensitivity and specificity. Conclusion: Our results indicate that VAI and LAP explain only a small percentage of the variation in the Framingham cardiovascular risk score. LAP index still deserves more attention in a cohort study, because, even with the limitations of a cross-sectional study, we observed an acceptable sensitivity for it so that the LAP can be used as a screening criterion for requesting more accurate tests.

Introducción: El producto de acumulación de lípidos (LAP) y el índice adiposo visceral (VAI) son marcadores clínicos de obesidad visceral y fueron propuestos como herramientas simples, económicas y precisas para estimar el riesgo cardiovascular y la mortalidad. El objetivo del estudio fue analizar la precisión de los índices VAI y LAP para el diagnóstico de personas con alto riesgo cardiovascular. Métodos: Se realizó un estudio observacional transversal de precisión en 193 pacientes de ambos sexos en la unidad de cardiología de un hospital universitario. Además de las variables VAI y LAP, se obtuvieron datos sociodemográficos, presencia de comorbilidades, escolaridad, nivel de actividad física y datos antropométricos para caracterizar la muestra. El riesgo cardiovascular se determinó mediante el Framingham Score. Resultados: No se observaron diferencias significativas en la muestra en la distribución por género (44,6% mujeres; 55,4% hombres), 24,4% riesgo cardiovascular bajo, 48,7% riesgo intermedio y 26,9% riesgo cardiovascular alto. El análisis de regresión lineal mostró que VAI y LAP explican, respectivamente, solo el 2,4% y el 5,2% de la variación del riesgo cardiovascular expresado por el Framingham Score. El análisis de áreas bajo la curva (AUC) para la característica operativa del receptor (ROC) indicó un efecto significativo solo de LAP para diagnosticar individuos con alto riesgo cardiovascular, pero con baja sensibilidad y especificidad. Conclusión: Nuestros resultados indican que VAI y LAP explican solo un pequeño porcentaje de la variación en la puntuación de riesgo cardiovascular de Framingham. El índice LAP aún merece más atención en un estudio de cohortes, ya que, aún con las limitaciones de un estudio transversal, observamos una sensibilidad aceptable del mismo para que el LAP pueda ser utilizado como criterio de cribado para solicitar pruebas más precisas.

ABSTRACT

Dragon fruit (Hylocereus genus) has the potential for the prevention of diseases associated with inflammatory and oxidative processes. We aimed to comprehensively review dragon fruit health effects, economic importance, and possible use in delivery systems. Pubmed, Embase, and Google Scholar were searched, and PRISMA (Preferred Reporting Items for a Systematic Review and Meta-Analysis) guidelines were followed. Studies have shown that pitaya can exert several benefits in conditions such as diabetes, dyslipidemia, metabolic syndrome, cardiovascular diseases, and cancer due to the presence of bioactive compounds that may include vitamins, potassium, betacyanin, p-coumaric acid, vanillic acid, and gallic acid. Moreover, pitaya has the potential to be used in food and nutraceutical products as functional ingredients, natural colorants, ecologically correct and active packaging, edible films, preparation of photoprotective products, and additives. Besides the importance of dragon fruit as a source of bioactive compounds, the bioavailability is low. The development of delivery systems such as gold nanoparticles with these compounds can be an alternative to reach target tissues.

ABSTRACT

Mangosteen (Garcinia mangostana L.), also known as the "queen of fruits", is a tropical fruit of the Clusiacea family. While native to Southeast Asian countries, such as Thailand, Indonesia, Malaysia, Myanmar, Sri Lanka, India, and the Philippines, the fruit has gained popularity in the United States due to its health-promoting attributes. In traditional medicine, mangosteen has been used to treat a variety of illnesses, ranging from dysentery to wound healing. Mangosteen has been shown to exhibit numerous biological and pharmacological activities, such as antioxidant, anti-inflammatory, antibacterial, antifungal, antimalarial, antidiabetic, and anticancer properties. Disease-preventative and therapeutic properties of mangosteen have been ascribed to secondary metabolites called xanthones, present in several parts of the tree, including the pericarp, fruit rind, peel, stem bark, root bark, and leaf. Of the 68 mangosteen xanthones identified so far, the most widely-studied are α-mangostin and γ-mangostin. Emerging studies have found that mangosteen constituents and phytochemicals exert encouraging antineoplastic effects against a myriad of human malignancies. While there are a growing number of individual research papers on the anticancer properties of mangosteen, a complete and critical evaluation of published experimental findings has not been accomplished. Accordingly, the objective of this work is to present an in-depth analysis of the cancer preventive and anticancer potential of mangosteen constituents, with a special emphasis on the associated cellular and molecular mechanisms. Moreover, the bioavailability, pharmacokinetics, and safety of mangosteen-derived agents together with current challenges and future research avenues are also discussed.

ABSTRACT

Modifications in the microbiota caused by environmental and genetic reasons can unbalance the intestinal homeostasis, deregulating the host's metabolism and immune system, intensifying the risk factors for the development and aggravation of non-alcoholic fat liver disease (NAFLD). The use of probiotics, prebiotics and synbiotics have been considered a potential and promising strategy to regulate the gut microbiota and produce beneficial effects in patients with liver conditions. For this reason, this review aimed to evaluate the effectiveness of probiotics, prebiotics, and symbiotics in patients with NAFLD and NASH. Pubmed, Embase, and Cochrane databases were consulted, and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines were followed. The clinical trials used in this study demonstrated that gut microbiota interventions could improve a wide range of markers of inflammation, glycemia, insulin resistance, dyslipidemia, obesity, liver injury (decrease of hepatic enzymes and steatosis and fibrosis). Although microbiota modulators do not play a healing role, they can work as an important adjunct therapy in pathological processes involving NAFLD and its spectrums, either by improving the intestinal barrier or by preventing the formation of toxic metabolites for the liver or by acting on the immune system.

ABSTRACT

Advancing age is one of the risk factors for developing many diseases, including cancer, cardiovascular disorders, and neurodegenerative alterations, such as mild cognitive impairment (MCI), and Alzheimer's Disease (AD). Studies have indicated that supplementation with resveratrol (RSV) might improve cerebrovascular function and reduce the risk of developing dementia. Thus, the aim of this systematic review was to assess the effects of RSV on MCI and AD. MEDLINE-PubMed, Cochrane, and EMBASE were used to perform the search, and PRISMA guidelines were followed. Five studies met the eligible criteria; three with AD and two with MCI. In AD patients, the use of RSV reduces Aß levels, improves brain volume, reduces the Mini-mental status score, and improves AD scores. In patients with MCI, this polyphenol prevents decline in Standard Volumes of Interest and increases the Resting-state Functional Connectivity score. RSV can activate the human silent information regulator 2/sirtuin 1 (Sirt-1) and can inhibit the cyclooxygenase-2 (COX-2), 5-lipoxygenase, and nuclear factor-κB, resulting in the reduction of the proinflammation pathways. It is also associated with the increase in the levels of interleukin (IL)-10 and reduction of interferon-γ and IL-17. Both anti-inflammatory and antioxidant effects can be related to preventing neurodegenerative diseases, doing maintenance, and enabling the recovery of these conditions directly related to inflammation and oxidative stress. We suggest that the use of RSV can bring beneficial effects to patients with MCI or AD.

ABSTRACT

Diabetes mellitus (DM) is an ensemble of metabolic conditions that have reached pandemic proportions worldwide. Pathology's multifactorial nature makes patient management, including lifelong drug therapy and lifestyle modification, extremely challenging. Currently, there is growing evidence about the effectiveness of using herbal supplements in preventing and controlling DM. Curcumin is a bioactive component found Curcuma longa, which exhibits several physiological and pharmacological properties such as antioxidant, anti-inflammatory, anticancer, neuroprotective, and anti-diabetic activities. For these reasons, our objective is to systematically review the effects of Curcuma longa or curcumin on DM. Databases such as PUBMED and EMBASE were searched, and the final selection included sixteen studies that fulfilled the inclusion criteria. The results showed that curcumin's anti-diabetic activity might be due to its capacity to suppress oxidative stress and inflammatory process. Also, it significantly reduces fasting blood glucose, glycated hemoglobin, and body mass index. Nanocurcumin is also associated with a significant reduction in triglycerides, VLDL-c, total cholesterol, LDL-c, HDL-c, serum C reactive protein, and plasma malonaldehyde. Therefore, it can be considered in the therapeutic approach of patients with DM.

ABSTRACT

Inflammatory bowel disease (IBD) is an umbrella term used to describe chronic inflammatory disorders related to a substantial reduction in the quality of life of patients. Some patients with Crohn's disease (CD) and ulcerative colitis (UC) are refractory to conventional therapies, and Curcuma longa derivatives have been considered as adjuvants. Owing to the anti-inflammatory and antioxidant effects, some clinical trials used this plant in the therapeutic approach of IBD, and some meta-analyses evaluated the outcomes found in these studies. Owing to controversial findings, our systematic review aimed to evaluate these studies to show whether C. longa compounds can still be considered in the therapeutic approach of patients with CD and UC. MEDLINE-PubMed, EMBASE, and Cochrane were searched, and Preferred Reporting Items for a Systematic Review and Meta-Analysis guidelines were followed. The results of the randomized clinical trials (RCTs) showed promising results with the use of curcumin in the therapeutic approach of both UC and CD patients. Some meta-analyses show controversial results, possibly due to the presence of bias in the included studies. The actions of curcumin are achieved by several mechanisms, such as reducing the expression of interleukin (IL)-1, IL-6, IL-12, and tumor necrosis factor-α. Moreover, it reduces the levels of reactive oxygen species, such as superoxide anions and malondialdehyde. The results of using curcumin in CD and UC patients are challenging to be evaluated because RCTs are variable in the dose and the formulations of curcumin, in the time of treatment, and the route of administration. The number of patients in the samples is also usually small.

ABSTRACT

INTRODUCTION: Despite significant advances in the study of Ulcerative colitis (UC) management, up to a third of patients may be refractory to conventional therapy, and specialists have considered natural compounds such as curcumin. AREA COVERED: The meta-analyzes found in the literature compare the effects of curcumin used in different administration routes or compare patients in remission with patients with active disease. Due to the biases in these studies, we performed a systematic review and meta-analysis of randomized clinical trials (RCTs) that investigated the efficacy of orally administrated curcumin in mild-to-moderate active UC. EXPERT OPINION: Curcumin produces relevant anti-inflammatory and antioxidant effects that are crucial in inducing remission in UC patients. Unfortunately, in the treatment of UC, we have not observed studies with standardization of dose and routes of administration. Existing meta-analyses are biased because they compare studies using different administration routes and patients in different stages of the disease. Our meta-analysis is the only one that tried to make a comparison with a few of biases as possible and show that curcumin can help in the induction of remission in UC subjects.

ABSTRACT

In the last years, scientists have shown that skeletal muscle is not a pure locomotor unit or responsible for propulsion and posture. Skeletal muscle encompasses one of the major organs of the body (constituting about 40% of the body mass in non-obese men). It regulates energy and metabolic processes and is now recognized as an organ capable of producing molecules with vital functions. These molecules are termed myokines, a new field of research in the health sciences, and represent an open field of discoveries and applications in several areas. The aim of this review was to show the role of some well-known myokines in the maintenance of homeostasis. Our search was performed in databases such as Medline/Pubmed, Embase and Scielo. Some relevant myokines are interleukin-6 (IL-6), IL-8, IL-15, irisin, myostatin, fibroblast growth factor 21 (FGF21), leukemia inhibitory factor (LIF), brain-derived neurotrophic factor (BDNF), and insulin-like growth factor-1 (IGF-1). They are related to play a positive or negative role in muscle function and metabolism homeostasis. They are associated with the regulation of glucose and lipid metabolism, the deposition of fat in the adipose tissue, and the "browning" of the white adipose tissue. For these reasons, they can interfere with the prevention of obesity, diabetes, metabolic syndrome, and cardiovascular diseases. The discovery of the myokines has opened a new direction in understanding the effects of exercises on humans.

ABSTRACT

Inflammatory bowel diseases (IBD) are characterized by a chronic and recurrent gastrointestinal condition, including mainly ulcerative colitis (UC) and Crohn's disease (CD). Cannabis sativa (CS) is widely used for medicinal, recreational, and religious purposes. The most studied compound of CS is tetrahydrocannabinol (THC) and cannabidiol (CBD). Besides many relevant therapeutic roles such as anti-inflammatory and antioxidant properties, there is still much controversy about the consumption of this plant since the misuse can lead to serious health problems. Because of these reasons, the aim of this review is to investigate the effects of CS on the treatment of UC and CD. The literature search was performed in PubMed/Medline, PMC, EMBASE, and Cochrane databases. The use of CS leads to the improvement of UC and CD scores and quality of life. The medical use of CS is on the rise. Although the literature shows relevant antioxidant and anti-inflammatory effects that could improve UC and CD scores, it is still not possible to establish a treatment criterion since the studies have no standardization regarding the variety and part of the plant that is used, route of administration and doses. Therefore, we suggest caution in the use of CS in the therapeutic approach of IBD until clinical trials with standardization and a relevant number of patients are performed.

ABSTRACT

OBJECTIVE: To test six variations in the Goldberg equation for evaluating the underreporting of energy intake (EI) among obese women on the waiting list for bariatric surgery, considering variations in resting metabolic rate (RMR), physical activity, and food intake levels in group and individual approaches. METHODS: One hundred obese women aged 20 to 45 years (33.3 ± 6.08) recruited from a bariatric surgery waiting list participated in the study. Underreporting assessment was based on the difference between reported energy intake, indirect calorimetry measurements and RMR (rEI:RMR), which is compatible with the predicted physical activity level (PAL). Six approaches were used for defining the cutoff points. The approaches took into account variances in the components of the rEI:RMR = PAL equation as a function of the assumed PAL, sample size (n), and measured or estimated RMR. RESULTS: The underreporting percentage varied from 55% to 97%, depending on the approach used for generating the cutoff points. The ratio rEI:RMR and estimated PAL of the sample were significantly different (p = 0.001). Sixty-one percent of the women reported an EI lower than their RMR. The PAL variable significantly affected the cutoff point, leading to different proportions of underreporting. The RMR measured or estimated in the equation did not result in differences in the proportion of underreporting. The individual approach was less sensitive than the group approach. CONCLUSION: RMR did not interfere in underreporting estimates. However, PAL variations were responsible for significant differences in cutoff point. Thus, PAL should be considered when estimating underreporting, and even though the individual approach is less sensitive than the group approach, it may be a useful tool for clinical practice.

ABSTRACT

A inflamação é uma resposta de defesa do organismo ao trauma ou a infecções por microorganismos. Na fase de término da inflamação e retorno à homeostase ocorrem mecanismos de regulação chamados de resolução onde há alternância de prostaglandinas pró-inflamatórias e leucotrienos a mediadores pró-resolução, produzidos a partir de ácidos graxos poliinsaturados ω3 (ácido eicosapentanóico e ácido docosapentanóico). A dieta interfere na composição de ácidos graxos das membranas celulares que serão metabolizados em compostos ativos chamados de resolvinas, protectinas e maresinas. Como as doenças inflamatórias têm papel importante na saúde pública o estudo destas substâncias e o delineamento de seus efeitos podem trazer novos horizontes no tratamento das doenças inflamatórias, com redução de custos e minimização de efeitos colaterais.


Inflammation is a defensive response to the trauma, infections or injury to the organism. When inflammation is ending occurs a program for active regulation called the resolution. This is accompanied by a class of lipid mediators where there is alternation of pro-inflammatory prostaglandins and leukotrienes to proresolution mediators, produced from 3 polyunsaturated fatty acids (eicosapentaenoic and docosapentanoicacid). The diet interferes the fatty acid composition of cell membranes that will be metabolized to active compounds called resolvins, protectins and maresins. The inflammatory diseases have an important rolein public health, so the study of these substances and delineation of their effects can bring new horizons in the treatment of inflammatory diseases, reducing costs and minimizing side effects.

ABSTRACT

This study aimed at evaluating glycemia and lipid profile of offspring from diabetic Wistar rats treated with Mentha piperita (peppermint) juice. Male offspring from nondiabetic dams (control group: 10 animals treated with water and 10 treated with peppermint juice) and from dams with streptozotocin-induced severe diabetes (diabetic group: 10 animals treated with water and 10 treated with peppermint juice) were used. They were treated during 30 days, and, after the treatment period, levels of glycemia, triglycerides, total cholesterol, and fractions were analyzed in the adult phase. The offspring from diabetic dams treated with peppermint showed significantly reduced levels of glucose, cholesterol, LDL-c, and triglycerides and significant increase in HDL-c levels. The use of the M. piperita juice has potential as culturally appropriate strategy to aid in the prevention of DM, dyslipidemia, and its complications.

ABSTRACT

Dry extract of the genus Passiflora has been shown to help control glycemia and lipid levels. The objective of this study was to evaluate the effects of passion fruit (P. edulis) on the biochemical profile of offspring from diabetic rats. Diabetes was induced by streptozotocin. The diabetes group consisted of 10 rats with glucose levels greater than 200 mg/dL; the nondiabetic (control) group consisted of 10 rats with glucose levels less than 120 mg/dL. After the diagnosis of diabetes, the mating phase was started. By day 21 of pregnancy, the offspring were born; the dams were kept in individual cages with their offspring until the weaning period. The offspring were then divided into 4 groups (n=15 each): G1 were offspring from control dams, G2 were offspring from treated nondiabetic dams, G3 were offspring from diabetic dams, and G4 were offspring from treated diabetic dams. For 30 consecutive days, G1 and G3 offspring were treated with vehicle (oral gavage) and G2 and G4 offspring were treated with passion fruit juice (oral gavage). After 30-day treatment, the animals were anesthetized and killed, and blood was drawn immediately for analysis of the biochemical profile (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, and glucose). The G2 and G4 rats showed significantly reduced total cholesterol, triglyceride, and low-density lipoprotein cholesterol levels and an increased high-density lipoprotein cholesterol level. The use of passion fruit juice improved lipid profiles, suggesting that this plant may have beneficial effects in the prevention and treatment of dyslipidemias and hyperglycemia.

ABSTRACT

Knowing that maternal diabetes is related to hyperglycemia and fetal hyperinsulinemia, which affect the lipid metabolism, the aim of this study was to evaluate the effects of Malpighia emarginata (acerola) juice on the glycemic and lipid profile of offspring of diabetic and nondiabetic Wistar rats. The adult offspring of non-diabetic dams and of dams with severe streptozotocin-induced diabetes were divided into groups: G1, offspring (of control dams) treated with water, G2, offspring (of diabetic dams) treated with water, G3, male offspring (of control dams) treated with acerola juice, and G4, male offspring (of diabetic dams) treated with acerola juice. The offspring of diabetic dams treated with acerola juice showed significantly decreased levels of glucose, cholesterol, triglycerides, and increased HDL-c. The use of acerola juice is a potential strategy to aid in the prevention of DM and dyslipidemia and its complications or to act as an auxiliary in the treatment of these diseases.

ABSTRACT

The aim of this study was to evaluate the effects of a nutrition education program (NEP) on anthropometric, dietetic, and metabolic parameters in high-risk subjects for type 2 diabetes mellitus. Fifty-one participants, both sexes, were randomly assigned to either the control (58.8%) or the intervention (NEP) group. The intervention group received frequent individual and group nutritional counseling from a team of nutritionists. Participants were assessed at baseline (M0) and after 12 months (M1) for anthropometric, dietetic, and metabolic parameters. The hypothesis was that high-risk subjects for type 2 diabetes mellitus participating in NEP would show an improvement in these parameters. At M1, the intervention group showed a significant decline in body weight (-3.4%), body mass index (-5.7%), cholesterol intake (-49.5%), fasting glycemia (-14.0%), fasting insulin (-9.0%), postprandial glycemia (-21.0%), postprandial insulin (-71.0%), total serum cholesterol (-23.0%), and glycated hemoglobin (-24.0%). A decrease in energy intake (5%, P = .06) and low-density lipoprotein cholesterol (25%, P = .07) was observed in the interventional group, although it did not reach statistical significance. In contrast, the control group presented a significantly higher energy intake (19%, P = .04) and a nonsignificant increase in consumption of all macronutrients. The long-term NEP was found to improve anthropometric, dietary, and metabolic parameters in high-risk subjects for type 2 diabetes mellitus.
