RESUMEN

Unlabelled: The COVID-19 pandemic has had a significant impact on the mental health of college students worldwide. As colleges shifted to online instruction, students faced disruptions and increased stressors, leading to a decline in mental health that appears to continue in the postpandemic era. To alleviate this problem, academic institutions have implemented various interventions to address mental health issues; however, many of these interventions focus on a single approach and lack diverse delivery methods. This viewpoint introduces the concept of a multimodal self-care online course, Life101: Mental and Physical Self-Care, and discusses the potential effectiveness of such an intervention in improving students' well-being. The course combines evidence-based interventions and incorporates interactive lectures, workshops, and guest speakers. Pre- and postcourse surveys were conducted over a span of 4 academic terms to evaluate the impact of this course on the well-being and self-care practices of students. The survey data suggest positive outcomes in students taking Life101, including the adoption of healthier habits, reduced stress levels, and increased knowledge and practice of self-care techniques. Life101 represents a novel multimodality intervention to address the epidemic of mental health issues faced by students today. By implementing similar evidence-based multimodal didactic curricula across campuses, academic institutions may be able to better equip students to navigate challenges and promote their overall well-being.

RESUMEN

Background: This study compared the impact of Short Message Service (SMS)-based education with traditional group-based education and the control group on body mass index, weight, and lifestyle in obese and overweight patients in a limited-resource country. It also compared the direct financial costs between the two intervention groups. Methods: In this controlled randomized educational study, 90 overweight or obese adults from four family physician clinics in Shiraz, Iran were randomly allocated to three training groups: SMS-based education, group-based education, and a control group. The participants' weight, body mass index (BMI), and waist circumference were measured at baseline, and the Physical Activity Scale questionnaire was completed. Group-based training was conducted in 1-hour weekly sessions. The SMS group received a text message each morning. The control group received routine care from a family physician. The intervention lasted 12 weeks. All participants were re-examined for the studied variables. Additionally, the direct costs were estimated, calculated, and compared. Results: The mean weight, BMI, and waist circumference changed significantly after 3 months compared to baseline in each group. The mean weight change differed significantly among the three groups (P-value=0.04), and the mean BMI changes were near significant (P-value=0.06). A post hoc comparison of changes in weight and BMI showed a significant difference between the control and SMS groups. SMS education incurred much lower costs for patients and healthcare services than group-based education. Conclusion: The study showed that SMS is an effective and cost-saving educational method for weight loss compared to group-based education, especially in developing countries.

RESUMEN

Angelica keiskei is a perennial plant, belonging to the Apiaceae family and originating from Japan. This plant has been reported to act as a diuretic, analeptic, antidiabetic, hypertensive, tumor, galactagogue, and laxative. The mechanism of action of A. keiskei is not known, but previous studies have suggested that it may act as an antioxidant. In this work, we used Drosophila melanogaster to evaluate the impact of A. keiskei on lifespan and healthspan and its potential anti-aging mechanism by conducting multiple assays on three fly strains: w1118, chico, and JIV. We observed that the extract extended lifespan and improved healthspan in a sex- and strain-dependent manner. A. keiskei extended lifespan and improved reproductive fitness in female flies and either had no effect or decreased survival and physical performance in males. The extract protected against the superoxide generator paraquat in both sexes. These sex-specific effects suggest that A. keiskei may act through age-specific pathways such as the insulin and insulin-like growth factor signaling (IIS) pathways. Upon examination, we found that the increased survival of A. keiskei-fed females was dependent on the presence of the insulin receptor substrate chico, supporting the role of IIS in the action of A. keiskei.

RESUMEN

Objectives: To learn about the mental health of students, the tools they use to cope with stress, and their perceptions toward the assistance they receive from their academic institutions during the COVID-19 pandemic. Participants: 593 students from two University of California campuses. Methods: The link to an anonymous survey was included in a mass email that was sent to students. Results: 87% of students expressed that their mental health has been negatively impacted by the pandemic, especially in students who already had diminished levels of self-reported mental health. Students articulated the need for increased financial, academic, and mental health support and that they want to have a voice in discussions that will lead to decisions that would impact them. Conclusion: Students reported that the pandemic has negatively impacted their mental health and that they wanted academic institutions to include them in the decision-making processes that would contribute to their health.

RESUMEN

Type 2 diabetes is the most prevalent endocrine disease in the world, and recently the gut microbiota have become a potential target for its management. Recent studies have illustrated that this disease may predispose individuals to certain microbiome compositions, and treatments like metformin have been shown to change gut microbiota and their associated metabolic pathways. However, given the limitations and side effects associated with pharmaceuticals currently being used for therapy of diabetes, there is a significant need for alternative treatments. In this study, we investigated the effects of a root extract from Rhodiola rosea in a Leptin receptor knockout (db/db) mouse model of type 2 diabetes. Our previous work showed that Rhodiola rosea had anti-inflammatory and gut microbiome-modulating properties, while extending lifespan in several animal models. In this study, treatment with Rhodiola rosea improved fasting blood glucose levels, altered the response to exogenous insulin, and decreased circulating lipopolysaccharide and hepatic C-reactive protein transcript levels. We hypothesize that these changes may in part reflect the modulation of the microbiota, resulting in improved gut barrier integrity and decreasing the translocation of inflammatory biomolecules into the bloodstream. These findings indicate that Rhodiola rosea is an attractive candidate for further research in the management of type 2 diabetes.

RESUMEN

Foreign body response (FBR) to biomaterials compromises the function of implants and leads to medical complications. Here, we report a hybrid alginate microcapsule (AlgXO) that attenuated the immune response after implantation, through releasing exosomes derived from human Umbilical Cord Mesenchymal Stem Cells (XOs). Upon release, XOs suppress the local immune microenvironment, where xenotransplantation of rat islets encapsulated in AlgXO led to >170 days euglycemia in immunocompetent mouse model of Type 1 Diabetes. In vitro analyses revealed that XOs suppressed the proliferation of CD3/CD28 activated splenocytes and CD3+ T cells. Comparing suppressive potency of XOs in purified CD3+ T cells versus splenocytes, we found XOs more profoundly suppressed T cells in the splenocytes co-culture, where a heterogenous cell population is present. XOs also suppressed CD3/CD28 activated human peripheral blood mononuclear cells (PBMCs) and reduced their cytokine secretion including IL-2, IL-6, IL-12p70, IL-22, and TNFα. We further demonstrate that XOs mechanism of action is likely mediated via myeloid cells and XOs suppress both murine and human macrophages partly by interfering with NFκB pathway. We propose that through controlled release of XOs, AlgXO provide a promising new platform that could alleviate the local immune response to implantable biomaterials.

RESUMEN

AIM: This study aimed to investigate the effect of adding ursodeoxycholic acid (UDCA) to phototherapy in neonates with glucose-6-phosphate dehydrogenase (G6PD) deficiency and hyperbilirubinaemia. G6PD deficiency is a common cause of severe hyperbilirubinaemia in neonates. METHODS: This study was a triple blind, clinical trial study of 40 neonates with G6PD deficiency and hyperbilirubinaemia who admitted for phototherapy in hospitals affiliated to the University of Medical Sciences. The treatment group (n = 20) received UDCA 10 mg/kg (2 cc/kg) daily divided into 2 doses every 12 h. The control group (n = 20) received the same volume of placebo syrup. The drug and placebo treatments were continued until the bilirubin level dropped below 171 µmol/L. Both the control and treatment group received continuous phototherapy. Independent sample t-test, survival analysis and logrank test were used to statistically analyse the results. RESULTS: The mean total bilirubin level was 231.9 ± 18.8 µmol/L and 184.3 ± 18.6 µmol/L in the control and intervention group respectively, 24 h after drug administration and 209.7 ± 19.3 µmol/L and 157.4 ± 16.4 µmol/L, respectively, 48 h after intervention (P < 0.05). The median length of hospitalisation in the treatment group was approximately 1 day lower than the control group (logrank test P value: <0.001). CONCLUSION: The study showed that the addition of UDCA to phototherapy accelerates the reduction of total bilirubin level in neonates with G6PD deficiency and can reduce the duration of hospitalisation.

RESUMEN

OBJECTIVE: The aims of this study were to evaluate the psychometric properties of Persian translation of the Yale Food Addiction Scale 2.0 (YFAS 2.0) as a widely accepted questionnaire for the first time and to establish a cut off score for Food Craving Questionnaire-Trait-reduced (FCQ-T-r). METHODS: In this cross-sectional study, 330 visitors of family physician clinics in Shiraz, a city located in south of Iran, were selected. The English version of YFAS 2.0 was translated into Persian and used in this study as well as the Persian version of FCQ-T-r. RESULTS: Confirmatory factor analysis of YFAS-2 confirmed one dimensional structure and factor loading in all eleven symptoms was above 0.4. Internal consistency for eleven symptoms was 0.813. Prevalence of food addiction in participants was 6.7% (22 participants). BMI and FCQ-T-r questionnaire score both were positively correlated with the number of food addiction symptoms but age was negatively correlated with the number of the symptoms. The ROC curve analysis showed the best suggested cut-off point for FCQ-T-r questionnaire to detect food addiction was 32.5. CONCLUSION: The present study confirmed validity and reliability of Persian version of YFAS-2. It is suggested that food addiction occurs in different level of food craving behavior in different food cultures or genetics.

RESUMEN

Objective: It has been shown that clinical practice may be a risk factor for job burnout. On the other hand, annual income may have a protective effect on job burnout. Clinical faculty in contrast to basic sciences faculty members have higher income but are involve in clinical practice. Comparison between these two groups can clarify which factors have greater influence on burnout. As a second aim for this study, reliability and validity of the Persian version of Maslach burnout inventory general survey (MBI-GS) were evaluated as well. Method : This cross-sectional study was conducted at Shiraz Medical School in Iran and a total of 241 faculty members were randomly selected and burnout was measured by the Persian version of the Maslach burnout inventory general survey (MBI-GS). Results: Comparison of burnout between the two groups indicated that clinical faculty showed significantly higher scores in the exhaustion dimension compared to the basic sciences faculty (p value = 0.017) but no significant differences were found between the two groups in other dimensions. Job satisfaction and income satisfaction were negatively correlated with exhaustion and cynicism dimensions, and job satisfaction was positively associated with professional efficacy (p value > 0.05). Internal consistency of the questionnaire was acceptable (α=0.77). Scaling success rate for discrimination and convergent validity were 100% except for convergent validity in the cynicism subscale. Correlation of all questions with their dimensions was equal to or more than 0.4 with the exception of item 13 in the cynicism subscale. Conclusion: Clinical faculty had higher burnout than basic sciences faculty especially in the exhaustion dimension. It has also been shown that income and job satisfaction are the most important factors which can predict professional burnout in medical faculty members. It is important for administrative and organizational decision makers to improve job engagement and decrease job abandonment. This study largely confirmed the 3-dimensional structure of the Persian version of MBI-GS.

RESUMEN

In a cytopathic effect inhibition assay, a standardized Rhodiola rosea root and rhizome extract, also known as roseroot extract (SHR-5), exerted distinct anti-influenza A virus activity against HK/68 (H3N2) (IC50 of 2.8 µg/mL) without being cytotoxic. For fast and efficient isolation and identification of the extract's bioactive constituents, a high-performance countercurrent chromatographic separation method was developed. It resulted in a three-stage gradient elution program using a mobile phase solvent system composed of ethyl acetate/n-butanol/water (1 : 4 : 5 → 2 : 3 : 5 → 3 : 2 : 5) in the reversed-phase mode. The elaborated high-performance countercurrent chromatographic method allowed for fractionation of the complex roseroot extract in a single chromatographic step in a way that only one additional orthogonal isolation/purification step per fraction yielded 12 isolated constituents. They cover a broad polarity range and belong to different structural classes, namely, the phenylethanoid tyrosol and its glucoside salidroside, the cinnamyl alcohol glycosides rosavin, rosarin, and rosin as well as gallic acid, the cyanogenic glucoside lotaustralin, the monoterpene glucosides rosiridin and kenposide A, and the flavonoids tricin, tricin-5-O-ß-D-glucopyranoside, and rhodiosin. The most promising anti-influenza activities were determined for rhodiosin, tricin, and tricin-5-O-ß-D-glucopyranoside with IC50 values of 7.9, 13, and 15 µM, respectively. The herein established high-performance countercurrent chromatographic protocol enables fast and scalable access to major as well as minor roseroot constituents. This is of particular relevance for extract standardization, quality control, and further in-depth pharmacological investigations of the metabolites of this popular traditional herbal remedy.

RESUMEN

Healthspan science aims to add healthy, functional years to human life. Many different methods of improving healthspan have been investigated, chiefly focusing on just one aspect of an organism's health such as survival. Studies in Drosophila melanogaster have demonstrated that a reversal to a long-abandoned ancestral diet results in improved functional health, particularly at later ages. Meanwhile, pharmaceutical studies have demonstrated that botanical extracts have potent antiaging properties, capable of extending the mean lifespan of D. melanogaster by up to 25%, without a decrease in early fecundity. In this study, we combine these two different approaches to healthspan extension to examine whether a combination of such treatments results in a synergistic or antagonistic effect on Drosophila healthspan. One botanical extract, derived from Rhodiola rosea, mimicked the effects of the ancestral apple diet with better performance at later ages compared with the control. Another extract, derived from Rosa damascena, decreased age-specific survivorship when combined with the apple diet providing support for the "Poisoned Chalice" hypothesis that combinations of various supplements or diets can elicit adverse physiological responses. More experiments in model organisms should be completed researching the effects of combining healthspan-extending substances in various diet backgrounds.

RESUMEN

OBJECTIVES: The typical immunosuppressive regimen of hematopoietic stem cell transplant includes cyclosporine. However, cyclosporine nephrotoxicity is a concern. We studied cyclosporine nephrotoxicity epidemiology in hematopoietic stem cell transplant patients and compared the pattern and urinary levels of the KIM-1 kidney injury molecule versus serum and urine creatinine levels. MATERIALS AND METHODS: The study covered 10 months at Namazi Hospital, Shiraz, Iran. All patients met the following criteria: > 15 years old, received allogenic hematopoietic stem cell transplant without history of acute or chronic kidney disease, and scheduled for at least 1 week of cyclosporine treatment. Urinary and serum levels of creatinine, urea, sodium, potassium, magnesium, and the KIM-1 kidney injury molecule were measured on days 0, 3, 5, 7, 10, and 14 of cyclosporine treatment. RESULTS: Of 42 patients, one-third developed cyclosporine nephrotoxicity (30.95%), and median onset time was 15 days. Hypokalemia and hypomagnesemia were reported in 76.2% and 53.4% of the cohort, respectively. None of the demographic, clinical, and paraclinical parameters was significantly associated with cyclosporine nephrotoxicity. Median duration of hospital stay for patients with cyclosporine nephrotoxicity (41 days) was significantly higher (P < .001) than those without nephrotoxicity (29 days). Area under the curve for receiver operating characteristic showed that accuracy of serum creatinine (0.267; 95% CI, 0.11-0.43) at day 0 of cyclosporine treatment was significantly lower (P = .017) than the accuracy of urine creatinine (0.477; 95% CI, 0.28-0.67) and urine levels of the KIM-1 kidney injury molecule (0.594; 95% CI, 0.41-0.78). CONCLUSIONS: Cyclosporine nephrotoxicity is a common adverse effect in the setting of hematopoietic stem cell transplant and occurs mostly within the first 2 weeks of cyclosporine treatment. Urine KIM-1 kidney injury molecule measurement had no overall superiority and no improved accuracy over serum or urine creatinine measurements for prediction or detection of cyclosporine nephrotoxicity.

RESUMEN

While great interest in health effects of natural product (NP) including dietary supplements and foods persists, promising preclinical NP research is not consistently translating into actionable clinical trial (CT) outcomes. Generally considered the gold standard for assessing safety and efficacy, CTs, especially phase III CTs, are costly and require rigorous planning to optimize the value of the information obtained. More effective bridging from NP research to CT was the goal of a September, 2018 transdisciplinary workshop. Participants emphasized that replicability and likelihood of successful translation depend on rigor in experimental design, interpretation, and reporting across the continuum of NP research. Discussions spanned good practices for NP characterization and quality control; use and interpretation of models (computational through in vivo) with strong clinical predictive validity; controls for experimental artefacts, especially for in vitro interrogation of bioactivity and mechanisms of action; rigorous assessment and interpretation of prior research; transparency in all reporting; and prioritization of research questions. Natural product clinical trials prioritized based on rigorous, convergent supporting data and current public health needs are most likely to be informative and ultimately affect public health. Thoughtful, coordinated implementation of these practices should enhance the knowledge gained from future NP research.

RESUMEN

Cinnamon extract has been reported to have positive effects in fruit fly and mouse models for Alzheimer's disease (AD). However, cinnamon contains numerous potential active compounds that have not been individually evaluated. The main objective of this study was to evaluate the impact of cinnamaldehyde, a known putative active compound in cinnamon, on the lifespan and healthspan of Drosophila melanogaster models for Alzheimer's disease, which overexpress Aß42 and MAPT (Tau). We found that cinnamaldehyde significantly improved the lifespan of both AD and non-AD flies. Cinnamaldehyde also improved the healthspan of AD flies overexpressing the Tau protein by improving climbing ability, evaluated by rapid iterative negative geotaxis (RING), and improving short-term memory, evaluated by a courtship conditioning assay. Cinnamaldehyde had no positive impact on the healthspan of AD flies overexpressing the Aß42 protein.

RESUMEN

Huntington's disease (HD) is a dominant, late-onset disease characterized by choreiform movements, cognitive decline, and personality disturbance. It is caused by a polyglutamine repeat expansion in the Huntington's disease gene encoding for the Huntingtin protein (Htt) which functions as a scaffold for selective macroautophagy. Mutant Htt (mHtt) disrupts vesicle trafficking and prevents autophagosome fusion with lysosomes, thus deregulating autophagy in neuronal cells, leading to cell death. Autophagy has been described as a therapeutic target for HD, owing to the key role Htt plays in the cellular process. Rhodiola rosea, a plant extract used in traditional medicine in Europe and Asia, has been shown to attenuate aging in the fly and other model species. It has also been shown to inhibit the mTOR pathway and induce autophagy in bladder cancer cell lines. We hypothesized that R. rosea, by inducing autophagy, may improve the phenotype of a Huntington's disease model of the fly. Flies expressing HttQ93 which exhibit decreased lifespan, impaired locomotion, and increased neurodegeneration were supplemented with R. rosea extract, and assays testing lifespan, locomotion, and pseudopupil degeneration provided quantitative measures of improvement. Based on our observations, R. rosea may be further evaluated as a potential therapy for Huntington's disease.

RESUMEN

BACKGROUND: The root extract of Rhodiola rosea has historically been used in Europe and Asia as an adaptogen, and similar to ginseng and Shisandra, shown to display numerous health benefits in humans, such as decreasing fatigue and anxiety while improving mood, memory, and stamina. A similar extract in the Rhodiola family, Rhodiola crenulata, has previously been shown to confer positive effects on the gut homeostasis of the fruit fly, Drosophila melanogaster. Although, R. rosea has been shown to extend lifespan of many organisms such as fruit flies, worms and yeast, its anti-aging mechanism remains uncertain. Using D. melanogaster as our model system, the purpose of this work was to examine whether the anti-aging properties of R. rosea are due to its impact on the microbial composition of the fly gut. RESULTS: Rhodiola rosea treatment significantly increased the abundance of Acetobacter, while subsequently decreasing the abundance of Lactobacillales of the fly gut at 10 and 40 days of age. Additionally, supplementation of the extract decreased the total culturable bacterial load of the fly gut, while increasing the overall quantifiable bacterial load. The extract did not display any antimicrobial activity when disk diffusion tests were performed on bacteria belonging to Microbacterium, Bacillus, and Lactococcus. CONCLUSIONS: Under standard and conventional rearing conditions, supplementation of R. rosea significantly alters the microbial community of the fly gut, but without any general antibacterial activity. Further studies should investigate whether R. rosea impacts the gut immunity across multiple animal models and ages.

RESUMEN

A new coumarin, (-)-cis-(3'R,4'R)-4'-O-angeloylkhellactone-3'-O-ß-d-glucopyranoside (1) and two new chalcones, 3'-[(2E)-5-carboxy-3-methyl-2-pentenyl]-4,2',4'-trihydroxychalcone (4) and (±)-4,2',4'-trihydroxy-3'-{2-hydroxy-2-[tetrahydro-2-methyl-5-(1-methylethenyl)-2-furanyl]ethyl}chalcone (5) were isolated from the aerial parts of Angelica keiskei (Umbelliferae), together with six known compounds: (R)-O-isobutyroyllomatin (2), 3'-O-methylvaginol (3), (-)-jejuchalcone F (6), isoliquiritigenin (7), davidigenin (8), and (±)-liquiritigenin (9). The structures of the new compounds were determined by interpretation of their spectroscopic data including 1D and 2D NMR data. All known compounds (2, 3, and 6-9) were isolated as constituents of A. keiskei for the first time. To identify novel hepatocyte proliferation inducer for liver regeneration, 1-9 were evaluated for their cell proliferative effects using a Hep3B human hepatoma cell line. All isolates exhibited cell proliferative effects compared to untreated control (DMSO). Cytoprotective effects against oxidative stress induced by glucose oxidase were also examined on Hep3B cells and mouse fibroblast NIH3T3 cells and all compounds showed significant dose-dependent protection against oxidative stress.

RESUMEN

Angelica keiskei (Miq.) Koidz. (Umbelliferae) has traditionally been used to treat dysuria, dyschezia, and dysgalactia as well as to restore vitality. Recently, the aerial parts of A. keiskei have been consumed as a health food. Various flavonoids, coumarins, phenolics, acetylenes, sesquiterpene, diterpene, and triterpenes were identified as the constituents of A. keiskei. The crude extracts and pure constituents were proven to inhibit tumor growth and ameliorate inflammation, obesity, diabetics, hypertension, and ulcer.
