What Is Wellbeing, and What Is Important for Wellbeing? Indigenous Voices from across Canada.

Indigenous peoples' perceptions of wellbeing differ from non-Indigenous constructs. Thus, it is imperative to recognize that Indigenous peoples will conceptualize wellbeing from their perspectives and set their own wellbeing priorities. In keeping with this viewpoint, the aims of the present study were to conceptualize wellbeing and determine what was (and is) important for wellbeing from Canadian Indigenous peoples' perspectives. In this paper, we take a partnership approach based on the elements of respect, equity, and empowerment. One primary data source and two existing data sources were examined and analyzed thematically utilizing a combination approach of deductive and inductive coding. Indigenous leadership and organizations viewed wellbeing holistically and conceptualized wellbeing multidimensionally. From across Canada, wellbeing was communicated as physical, economic, political, social, and cultural. The scaling of wellbeing represented a collectivist perspective, and land was the connecting thread between all types of wellbeing, being a place to practice cultural traditions, reassert one's Indigenous identity, find solace, and pass on Indigenous knowledge and languages. Although wellbeing was discussed in the context of the individual, family, community, and nation, wellbeing was most often discussed at the cultural level by regional and national Indigenous leadership and organizations. Even in acknowledging the great cultural diversity among Canadian Indigenous nations, four concordant themes were identified regionally and nationally, with respect to what was important for cultural wellbeing: land and water, sustainability, and inherent obligations; being on the land, and indigenous languages and knowledge systems; sustainable development; and meaningful involvement in decision-making, and free, prior, and informed consent. Taking into account these themes is foundational for any interaction with Indigenous peoples, especially in the context of land, culture, and development. There needs to be a new beginning on the journey to reconciliation with land and cultural wellbeing at the forefront.

Indigenous land-based approaches to well-being: The Sibi (River) program in subarctic Ontario, Canada.

The Albany River system holds a special significance for the Omushkego Cree of subarctic Ontario, Canada, embodying their cultural roots, history, and the Cree way of life and worldviews. Through the Sibi program, youth learned traditional fishing practices from Elders and on-the-land experts, gaining valuable knowledge on the land and river. The program addressed barriers to being on the land, while also creating a space for the transfer of Indigenous knowledge and revitalising community social networks. The program took place in the summer, following the Omushkego Cree's seasonal cycle and employed community-based participatory research approach. Photovoice and semi-structured interviews were used to identify elements of well-being from an Indigenous perspective. Regardless of age or experience, participants expressed positive emotions while being on the land, highlighting how strengthening social and community networks, intergenerational knowledge transfer, and fostering cultural continuity contribute to improved well-being. Program outcomes emphasize the importance of collaboration with communities to gain insights into their needs, priorities, and values, ultimately creating more sustainable and effective well-being programs. By fostering engagement and recognizing the environment's significance, sustainable and long-term solutions can be pursued to address challenges faced by communities, ultimately advancing health and well-being for both present and future generations.The Albany River system holds a special significance for the Omushkego Cree of subarctic Ontario, Canada, embodying their cultural roots, history, and the Cree way of life and worldviews.

Chicken soup for the skin!

Chicken soup is a worldwide dish used in folk medicine to treat respiratory infections. In ancient and medieval times, it was used to treat leprosy. Anecdotally, it is claimed that chicken soup promotes healthy skin because it is rich in collagen and hyaluronic acid. One clinical study found that consumption of chicken soup by human individuals increased skin elasticity and decreased facial pigmentation. More research is needed to confirm these benefits and better define the role chicken soup consumption might have in promoting healthy, youthful skin.

Impact of Azo Dyes and Ibuprofen on the Proteome of Serratia nematodiphila sp. MB307.

BACKGROUND: Micropollutants comprise organic/mineral substances that cause an undesirable impact on the environment, by affecting life at all scales. In this study, we explored the changes they impart on the global proteome of a soil bacterium Serratia nematodiphila MB307, for two classes of pollutants, i.e., Azo dyes (Methyl orange, Congo red) and a pharmaceutical (Ibuprofen). METHODS: The 100 µg pollutant supplemented alteration of pure S. nematodiphila MB307 culture after 24 hours of incubation at 37 °C and its control was analyzed using a differential proteomics approach. MaxQuant software with the Perseus package was used for data analysis purposes. RESULTS: Prominently, ribosomal proteins and chaperones were up or downregulated in the whole cell and membranous fraction. CONCLUSION: This illustrates dynamic protein production adaptation of bacteria, to cope with stress and cell growth/division trade-off for survival. A collective pattern of survival under stress or pollution resistance could not be decrypted for all classes of pollutants, portraying dissimilar mechanisms of coping with differently structured pollutant moieties.

The Avicenna lunar crater.

Fifty years ago, in 1970, a lunar crater was named in honor of Avicenna, one of the most influential physicians of the Medieval period. His encyclopedic work, The Canon of Medicine, attempted to codify all medical knowledge including dermatology. This contribution provides a brief overview of Avicenna, his contributions to medicine and dermatology, and the lunar crater named after him.

Active surveillance of metastatic renal cell carcinoma: Results from a prospective observational study (MaRCC).

BACKGROUND: Systemic therapy (ST) can be deferred in patients who have metastatic renal cell carcinoma (mRCC) and slow-growing metastases. Currently, this subset of patients managed with active surveillance (AS) is not well described in the literature. METHODS: This was a prospective observational study of patients with mRCC across 46 US community and academic centers. The objective was to describe baseline characteristics and demographics of patients with mRCC initially managed by AS, reasons for AS, and patient outcomes. Descriptive statistics were used to characterize demographics, baseline characteristics, and patient-related outcomes. Wilcoxon 2-sample rank-sum tests and χ2 tests were used to assess differences between ST and AS cohorts in continuous and categorical variables, respectively. Kaplan-Meier survival curves were used to assess survival. RESULTS: Of 504 patients, mRCC was initially managed by AS (n = 143) or ST (n = 305); 56 patients were excluded from the analysis. Disease was present in 69% of patients who received AS, whereas the remaining 31% had no evidence of disease. At data cutoff, 72 of 143 patients (50%) in the AS cohort had not received ST. The median overall survival was not reached (95% CI, 122 months to not estimable) in patients who received AS versus 30 months (95% CI, 25-44 months) in those who received ST. Quality of life at baseline was significantly better in patients who were managed with AS versus ST. CONCLUSIONS: AS occurs frequently (32%) in real-world clinical practice and appears to be a safe and appropriate alternative to immediate ST in selected patients.

Impact of stimulus duration on motor unit thresholds and alternation in compound muscle action potential scans.

OBJECTIVE: To investigate the impact of stimulus duration on motor unit (MU) thresholds and alternation within compound muscle action potential (CMAP) scans. METHODS: The stimulus duration (0.1, 0.2, 0.6, and 1.0 ms) in thenar CMAP scans and individual MUs of 14 healthy subjects was systematically varied. We quantified variability of individual MU's thresholds by relative spread (RS), MU thresholds by stimulus currents required to elicit target CMAPs of 5% (S5), 50% (S50) and 95% (S95) of the maximum CMAP, and relative range (RR) by 100*[S95-S5]/S50. We further assessed the strength-duration time constant (SDTC). Experimental observations were subsequently simulated to quantify alternation. RESULTS: RS, unaffected by stimulus duration, was 1.65% averaged over all recordings. RR increased for longer stimulus duration (11.4% per ms, p < 0.001). SDTC shortened with higher target CMAPs (0.007 ms per 10% CMAP, p < 0.001). Experiments and simulations supported that this may underlie the increased RR. A short compared to long stimulus duration recruited relative more MUs at S50 (more alternation) than at the tails (less alternation). CONCLUSIONS: The stimulus duration significantly affects MU threshold distribution and alternation within CMAP scans. SIGNIFICANCE: Stimulation settings can be further optimized and their standardization is preferred when using CMAP scans for monitoring neuromuscular diseases.

Health and Wellness Impacts of Traditional Physical Activity Experiences on Indigenous Youth: A Systematic Review.

Traditional physical activities have numerous physiological and psychosocial benefits for Indigenous youth around the world. Little is known about the positive health and wellness impacts of traditional physical activity experiences on Indigenous youths. The aim of this systematic review is to explore the holistic health and wellness impacts of traditional physical activities on Indigenous youth from certain North American and Oceania geographic areas. A systematic search of four electronic databases (PubMed, ERIC, Scopus and Web of Science) was conducted to identify peer-reviewed publications of qualitative research exploring the diverse health experiences of traditional physical activities for Indigenous youth in Canada, the United States of America, New Zealand and Australia. A qualitative synthesis of studies between 2006 and 2018 were included, and findings were synthesized using an integrated Indigenous-ecological model, which broadly captures health and wellness impacts under intrapersonal, interpersonal, organizational, community and policy level outcomes using medicine wheel teachings. In total, nine studies were identified via this search. Overall, the literature described numerous emotional, mental and spiritual benefits of traditional physical activity, and youth experiences were affected by familial and communal relationships, and systemic factors. Among Indigenous youth, this research shows the importance of including traditional physical activity in future programs and partnerships with community expertise.

Fisher's Linear Discriminant Function Analysis and its Potential Utility as a Tool for the Assessment of Health-and-Wellness Programs in Indigenous Communities.

Diabetes mellitus is a growing public health problem affecting persons in both developed and developing nations. The prevalence of type 2 diabetes mellitus (T2DM) is reported to be several times higher among Indigenous populations compared to their non-Indigenous counterparts. Discriminant function analysis (DFA) is a potential tool that can be used to quantitatively evaluate the effectiveness of Indigenous health-and-wellness programs (e.g., on-the-land programs, T2DM interventions), by creating a type of pre-and-post-program scoring system. As the communities of the Eeyou Istchee territory, subarctic Quebec, Canada, have varying degrees of isolation, we derived a DFA tool for point-of-contact evaluations to aid in monitoring and assessment of health-and-wellness programs in rural and remote locations. We developed several DFA models to discriminate between those with and without T2DM status using age, fasting blood glucose, body mass index, waist girth, systolic and diastolic blood pressure, high-density lipoprotein, triglycerides, and total cholesterol in participants from the Eeyou Istchee. The models showed a ~97% specificity (i.e., true positives for non-T2DM) in classification. This study highlights how varying risk factor models can be used to discriminate those without T2DM with high specificity among James Bay Cree communities in Canada.

Presumptive spondylogenic pruritus: a case study.

OBJECTIVE: To describe a case of a patient with chronic pruritus of the upper back and arms who underwent complete resolution of his complaint following a short course of chiropractic care. CASE PRESENTATION: A 36-year-old male suffering with chronic, severe pruritus affecting the upper back and both arms, presented for chiropractic treatment after pharmacological treatment and dietary restrictions failed to resolve his complaint. Physical examination revealed restrictions of thoracic and cervical intervertebral motion. However, radiological examination did not identify any substantial pathology of the spine. Following a short course of chiropractic treatment, which included spinal manipulation and home exercises, his complaint of pruritus resolved completely. SUMMARY: In this case, a severe and chronic complaint of pruritus which was refractory to other forms of care resolved quickly after the institution of chiropractic care. It is therefore hypothesized that the patient's pruritus was etiologically linked to biomechanical problems of the spine.

OBJECTIF: Décrire le cas d'un patient présentant un prurit chronique à la partie supérieure du haut du dos et aux bras qui est complètement disparu après une courte période de traitements chiropratiques. EXPOSÉ DU CAS: Un homme de 36 ans souffrant d'un prurit chronique grave à la partie supérieure du dos et aux deux bras s'est présenté à une clinique chiropratique après avoir suivi un traitement pharmacologique et un régime alimentaire qui se sont avérés infructueux. L'examen physique a révélé une limitation de la mobilité articulaire de la colonne dorsale et de la colonne cervicale. L'examen radiologique n'a révélé aucune pathologie grave de la colonne vertébrale. Après une brève période de séances chiropratiques par manipulations vertébrales et un programme d'exercices à domicile, le prurit est complètement disparu. RÉSUMÉ: Dans ce cas, un prurit grave et chronique, réfractaire à d'autres formes de traitement, est disparu rapidement après le commencement des traitements chiropratiques. On peut donc supposer que le prurit du patient était lié à des troubles biomécaniques de la colonne vertébrale.

Along came a spider: Medicine's most famous spider eponyms.

Spiders have long been admired for the beauty of their webs. They are celebrated in popular culture as well as in medical eponyms. This contribution provides the historical background for three spider-related eponyms: nevus araneus (spider angioma), arachnodactyly, and the arachnoid mater. Nevus araneus was first named and described by Sir Erasmus Wilson in 1842. Arachnodactyly was described in 1896 by Antoine Marfan using the term pattes d'araignée, which means spider legs. In 1902, Emile Charles Achard proposed the term arachnodactyly for this clinical finding. The arachnoid mater had been named in 1699 by Frederik Ruysch. The clinical management of spider bites from the only two dangerous venomous spiders within the United States, the black widow spider (Latrodectus mactans) and the brown recluse spider (Loxosceles reclusa), is reviewed.

The influence of dietary supplementation with cranberry tablets on the urinary risk factors for nephrolithiasis.

PURPOSE: Cranberry supplements are commonly used as a natural deterrent to urinary tract infection. However, one small study (n = 5) which showed an increase in urinary oxalate levels following cranberry supplementation has led to its use with caution among patients susceptible to nephrolithiasis. Furthermore, most commonly available cranberry tablet preparations contain vitamin C, which has been independently shown to increase urinary oxalate excretion. The aim of this study is to investigate the influence of cranberry supplementation on urinary oxalate excretion. METHODS: Fifteen participants were randomised to receive cranberry tablets alone or cranberry tablets containing vitamin C. Tablets were taken at the manufacturers recommended dosage for a period of 14 days. Participants provided a 24 h urine collection at trial entry and day 14. Urinary variables were compared to assess for changes in oxalate levels. RESULTS: The median age was 27 years (21-43). There was no difference in the 24 h urine volume pre or post commencement of cranberry tablets (1.7 vs 2 L, p = 0.07). An increase in median urinary oxalate excretion was observed in participants taking both cranberry-only tablets (0.10 mmol/day) and tablets containing vitamin C (1.15 mmol/day). CONCLUSION: Dietary supplementation with cranberry increases urinary oxalate excretion and should be avoided in patients at risk of urolithiasis.

Impact of Melaleuca quinquenervia Biochar on Phaseolus vulgaris Growth, Soil Nutrients, and Microbial Gas Flux.

Biochar has been heralded for improving soil quality, sequestering C, and converting organic residues into value-added amendments. Biochar research in agricultural settings has been primarily conducted on acidic soils, with few studies evaluating biochar effects on alkaline soils. Given the rise of small-scale, sustainable farmers experimenting with biochar in South Florida's alkaline, carbonaceous soil, this study sought to assess biochar use in South Florida using an invasive plant species as a feedstock. (Cav.) S.T. Blake biomass was converted into biochar to measure how application at two rates, 2 and 5% (w/w), affects plant growth, soil macro- and micronutrients, and microbial gas flux (CO) in a potted greenhouse experiment using L. Plant growth was inhibited with biochar addition at the 2 and 5% rates. Dry shoot, pod weight, and pod length decreased significantly between treatments ( < 0.001). Significant reductions in plant-available P, Ca, Mg, Cu, and Zn were observed in the 5% biochar soil postharvest ( < 0.05). Compared with the control, addition of biochar at 2 and 5% rates significantly reduced CO flux during the growing season, but not at harvest ( < 0.01). Our results indicate that those considering biochar application in South Florida's alkaline soil should be cautious in selecting feedstock and temperature for biochar production. Biochar can be produced at lower temperatures to decrease pH, but the concomitant increase in volatile matter (VM) is of concern. Although CO flux may have decreased, the deleterious impacts of biochar (pH = 8.12, VM = 26.5%) on production should not be dismissed.

Body burdens, sources and interrelations of selected toxic and essential elements among the nine Cree First Nations of Eeyou Istchee, James Bay region of northern Quebec, Canada.

BACKGROUND: this article constitutes a report on the comprehensive Nituuchischaayihtitaau Aschii multi-community environment-and-health study conducted among the Cree peoples (Eeyouch) of northern Quebec, Canada. OBJECTIVES: to interpret observed concentrations of a suite of chemical elements in a multi-media biological monitoring study in terms of sources and predictors. METHODS: the concentrations of 5 essential and 6 toxic chemical elements were measured in whole blood, and/or in urine or hair by ICP-MS. Concentrations of essential elements are compared to those considered normal (i.e., required for good health) and, when toxic, deemed acceptable at specified concentrations in public health guidelines. Their dependence on age, sex, the specific community lived-in and diet were explored employing multivariate analysis of variance (MANOVA) involving new variables generated by principle component analysis (PCA) and correspondence analysis (CA). RESULTS: the 5 most prominent PCA axes explained 67.7% of the variation, compared to 93.0% by 6 main CA factors. Concentrations of the essential elements in whole blood (WB) and iodine(i) and arsenic (As) in urine were comparable to those reported in the recent Canadian Health Measures survey and are assigned to dietary sources. By contrast, WB cadmium (Cd) was elevated even when smoking was considered. Mercury (Hg) concentrations in WB and hair were also higher in adults, although comparable to those observed for other indigenous populations living at northern latitudes. Fish consumption was identified as the prominent source. Of the 5 coastal communities, all but one had lower Hg exposures than the four inland communities, presumably reflecting the type of fish consumed. Use of firearms and smoking were correlated with WB-lead (Pb). The concentrations of both Hg and Pb increased with age and were higher in men, while WB-Cd and smoking prevalence were higher in women when considering all communities. Hg and Pb were low in children and women of reproductive age, with few exceedances of health guidelines. Although individuals with T2D had somewhat lower WB-Cd, there is some indication that Cd may potentiate renal dysfunction in this subgroup. Plots of selected CA axes grouped those elements expected to be in a normal diet and distinguished them from those with well-known unique sources (especially Hg and As in hair; and Hg, Pb and Cd in WB). CONCLUSIONS: the use of multiple biological media in conjunction with the complementary PCA and CA approaches for constructing composite variables allowed a more detailed understanding of both the sources of the essential and toxic elements in body fluids and the dependencies of their observed concentrations on age, sex, community and diet.

Human Hepatic HepaRG Cells Maintain an Organotypic Phenotype with High Intrinsic CYP450 Activity/Metabolism and Significantly Outperform Standard HepG2/C3A Cells for Pharmaceutical and Therapeutic Applications.

Conventional in vitro human hepatic models for drug testing are based on the use of standard cell lines derived from hepatomas or primary human hepatocytes (PHHs). Limited availability, interdonor functional variability and early phenotypic alterations in PHHs restrict their use, whilst standard cell lines such as HepG2 lack a substantial and variable set of liver-specific functions such as CYP450 activity. Alternatives include the HepG2-derivative C3A cells selected as a more differentiated and metabolically active hepatic phenotype. Human HepaRG cells are an alternative organotypic co-culture model of hepatocytes and cholangiocytes reported to maintain in vivo-like liver-specific functions, including intact Phase I-III drug metabolism. In this study, we compared C3A and human HepaRG cells using phenotypic profiling, CYP450 activity and drug metabolism parameters to assess their value as hepatic models for pre-clinical drug testing or therapeutics. Compared with C3As, HepaRG co-cultures exhibit a more organotypic phenotype, including evidence of hepatic polarity with the strong expression of CYP3A4, the major isoform involved in the metabolism of over 60% of marketed drugs. Significantly greater CYP450 activity and expression of CYP1A2, CYP2E1 and CYP3A4 genes in HepaRG cells (comparable with that of human liver tissue) was demonstrated. Moreover, HepaRG cells also preferentially expressed the hepatic integrin α5 ß1 - an important modulator of cell behaviour including growth and survival, differentiation and polarity. Drug metabolite profiling of phenacetin (CYP1A2) and testosterone (CYP3A4) using LC-MS/MS and HPLC, respectively, revealed that HepaRGs had more intact (Phase I-II) metabolism profile. Thus, HepaRG cells significantly outperform C3A cells for the potential pharmaceutical and therapeutic applications.

Menstrual cycle perturbation by organohalogens and elements in the Cree of James Bay, Canada.

Persistent organohalogens (POHs) and metals have been linked to alterations in menstrual cycle function and fertility in humans. The Cree First Nations people living near James Bay in Ontario and Quebec, Canada, have elevated levels of POHs, mercury and lead compared to other Canadians. The present study examines the interrelationships between selected POHs and elements on menstrual cycle function in these Cree women. Menstrual cycle characteristics were derived from structured daily diaries and endocrine measurements from daily urine samples collected during one cycle for 42 women age 19-42. We measured 31 POHs in blood plasma and 18 elements in whole blood, for 31 of the participants. POHs and elements detected in ≥ 70% of the participants were transformed by principal component (PC) analysis to reduce the contaminant exposure data to fewer, uncorrelated PCA variables. Multiple regression analysis revealed that, after adjusting for confounders, PC-3 values showed significant negative association with cycle length, after adjusting for confounders (p = 0.002). PC-3 accounted for 9.2% of the variance and shows positive loadings for cadmium, selenium, and PBDE congeners 47 and 153, and a negative loading for copper. Sensitivity analysis of the model to quantify likely effect sizes showed a range of menstrual cycle length from 25.3 to 28.3 days using the lower and upper 95% confidence limits of mean measured contaminant concentrations to predict cycle length. Our observations support the hypothesis that the menstrual cycle function of these women may be altered by exposure to POHs and elements from their environment.
