Follow-up of the re-evaluation of quillaia extract (E 999) as a food additive and safety of the proposed extension of uses.

Quillaia extract (E 999) was re-evaluated in 2019 by the EFSA Panel on Food Additives and Flavourings (FAF). EFSA derived an acceptable daily intake (ADI) of 3 mg saponins/kg bw per day for E 999. Following a European Commission call for data to submit data to fill the data gaps, the present follow-up opinion assesses data provided by interested business operators (IBOs) to support an amendment of the EU specifications for E 999. Additionally, this opinion deals with the assessment of the proposed extension of use for E 999 in food supplements supplied in a solid and liquid form, excluding food supplements for infants and young children and, as a carrier in botanical nutrients. The Panel concluded that the proposed extension of use, if authorised, could result in an exceedance of the ADI at the maximum of the ranges of the mean for children, adolescents and the elderly, and for all populations at the 95th percentile. An additional proposed extension of use for E 999 to be used as a carrier for glazing agents on entire fresh fruits and vegetables has been received. Since no information on the proposed use levels of E 999 on a saponins content basis has been provided by this applicant, the Panel was not able to evaluate the safety of this extension of use. Considering the technical data submitted, the Panel recommended some modifications of the existing EU specifications for E 999, mainly to lower the limits for lead, mercury and arsenic and to include a maximum limit for cadmium and for calcium oxalate. The Panel also recommended that the limits would be expressed on a saponins basis. The Panel proposed to revise the definition of E 999 to better describe the composition in a qualitative way.

Efficacy of photobiomodulation therapy combined with mobile health education in patients with head and neck cancer suffering from chronic xerostomia after radiotherapy: protocol for a three-arm, randomised, placebo-controlled, double-blinded study.

INTRODUCTION: The role of photobiomodulation (PBM) therapy for oral tissue damage induced by cancer treatment is currently unclear, and there is low-quality to moderate-quality evidence supporting the use of this approach for treating xerostomia and/or hyposalivation. Consequently, patients with head and neck cancer increasingly turn to basic oral hygiene to alleviate salivary gland dysfunction, and their adherence can be improved by mobile health (mHealth) education. The primary objective of this study will be to analyse the effects of different doses of PBM therapy (7.5 J/cm2 vs 3 J/cm2) plus mHealth education on quality of life (QoL), oral health, salivary secretion and salivary gland ultrasound assessment at postintervention and at the 6-month follow-up in patients with head and neck cancer after radiotherapy compared with those in control group. METHODS AND ANALYSIS: A prospective, three-arm, randomised, placebo-controlled, double-blinded study will be conducted among patients with head and neck cancer suffering from chronic xerostomia. A total of 20 patients per arm will be included and randomly assigned to receive 7.5 J/cm2 of PBM, 3 J/cm2 of PBM or placebo therapy. PBM therapy will be applied during 24 sessions at 22 points extra and intraorally two times per week for 3 months, combined with a mobile application (https://www.laxer.es). The assessments will be recorded at the beginning of the study, at postintervention and at the 6-month follow-up. The primary outcomes will be QoL, oral health, salivary secretion and salivary gland ultrasound. The pain pressure threshold, functional performance, mood and sleep quality will be secondary indicators. ETHICS AND DISSEMINATION: This study received ethics approval from the Andalusian Biomedical Research Ethics Portal (2402-N-21 CEIM/CEI Provincial de Granada) according to the Declaration of Helsinki for Biomedical Research. The results of this study will be presented at national and international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT05106608.

Chemical Characterization of Polysaccharide Extracts Obtained from Pomace By-Products of Different White Grape Varieties.

Grape pomace is one of the main by-products in the wine industry and contains some high-added-value compounds, such as polysaccharides. Considering the wide application possibilities of polysaccharides in wine and in the food industry, the revalorization of grape pomace to extract polysaccharides presents itself as an opportunity for by-product management. Therefore, the aim of this study was to characterize polysaccharide extracts obtained from pomace by-products of different white grape varieties. The type and content of polysaccharides, proteins and phenols were analyzed. Statistically significant differences were found between the varietal extracts in the types and concentrations of polysaccharides. The extracts obtained from the Verdejo and Puesta en Cruz varieties showed the highest polysaccharide purity and contents, but the type of polysaccharides was different in each case. The Verdejo provided extracts richer in non-pectic polysaccharides, while the Puesta en Cruz provided extracts richer in pectic polysaccharides. The protein and polyphenol contents were low in all extracts, below 2.5% and 3.7%, respectively. These results open up a new possibility for the revalorization of grape pomace by-products to obtain polysaccharide-rich extracts, although it would be interesting to improve both the yield and the purity of the extracts obtained by studying other extraction techniques or processes.

Knight by force and wounded, protecting without a shield: A meta-ethnography of men's experiences after an involuntary pregnancy loss.

OBJECTIVE: To synthesize the available body of qualitative research regarding the experiences of men after an involuntary pregnancy loss. DESIGN: Noblit and Hare's interpretive meta-ethnography of 13 original qualitative articles was carried out. RESULTS: After reciprocal and refutational translations, the lines of argument synthesis were developed, together with the metaphor "Knight by force and wounded, protecting without a shield." This metaphor symbolizes the experience of men after an involuntary pregnancy loss. CERQual assessment showed that the results are a (highly) reasonable representation of the phenomenon of interest. CONCLUSIONS: The men attempted to cope with the loss of fatherhood and suffering, while managing the lack of social recognition and social expectations of masculinity in terms of their behaviour and expression of suffering. They tended to be strong, although they did not always have the necessary support or knowledge. IMPLICATIONS FOR PRACTICE: Comprehensive and individualized care that includes the man is required. This requires the theoretical-practical training of nurses and midwives, and the provision of tools that help the emotional management of emotionally demanding care.

Real-world experience of intravenous iron sucrose supplementation and dynamics of soluble transferrin receptor and hepcidin in a Spanish cohort of absolute iron deficient patients.

The study evaluated the safety and effectiveness of the generic intravenous (IV) iron treatment (Feriv®), in a Spanish cohort with absolute iron deficiency (ID) (serum ferritin <50 ng/ml, with or without anaemia) (n = 122; 91% women; median age of 44 years [IQR: 33.7-54]). Iron-related biomarkers were measured before treatment (baseline), 2 weeks after beginning the protocol (intermediate control, IC) and between 7 and 10 days after treatment completion (final time-point). Primary efficacy endpoints were ferritin levels ≥ 50 ng/ml, anaemia restoration or an increase in haemoglobin (Hb) of at least one point in patients without baseline anaemia. After treatment, iron-related biomarkers improved, including ferritin, Hb, sideremia, transferrin, transferrin saturation index, soluble transferrin receptor (sTfR), and hepcidin. Baseline ferritin concentration (13.5 ng/ml [IQR: 8-24.2]) increased at the IC and continued rising at the final time-point, reaching a median ferritin of 222 ng/ml and 97.3% of patients ≥ 50 ng/ml. At the final time-point, anaemia prevalence decreased from 26.2% to 5%, while the 34.1% without baseline anaemia showed an increase in Hb of at least one point. Headache was the only drug-adverse event recorded in 2.3% of patients. At a late time-point (27.5 median weeks after ending therapy [IQR: 22-40]), evaluated in a subgroup of 66 patients, 18% had ferritin levels < 50 ng/ml. Multivariate analysis showed that low baseline ferritin and high sTfR/hepcidin ratio tended to be independently associated with ID recurrence. Feriv® is a safe, effective first-line treatment for absolute ID, with improvement of serum ferritin and Hb. ID recurrence was associated with the baseline degree of iron stores depletion, indicated by serum ferritin, and sTfR/hepcidin ratio.

Estrategias de control de la Equinococosis quística en el Uruguay / Strategies for the control of cystic echinococcosis in Uruguay / Estratégias de controle da equinococose cística no Uruguai

La equinococosis quística es una zoonosis de origen parasitario con distribución cosmopolita. En nuestro país continúa siendo una enfermedad endémica, afectando principalmente pequeños centros poblados y áreas rurales pobres relacionadas a la producción ovina. Los planes de control requieren de un abordaje holístico, con la participación de diferentes instituciones, profesionales y en especial de la comunidad. La cooperación regional busca monitorizar el avance de la enfermedad y centrar las medidas de acción sobre cuatro ejes, definidos según los puntos de intervención más comunes para la quiebra del ciclo de transmisión y la consecuente reducción en incidencia y prevalencia de la enfermedad. La presente revisión utilizó literatura obtenida en diferentes bases de datos, bibliotecas virtuales y sitios web regionales y locales con el objetivo describir las principales estrategias de control, vigilancia y prevención aplicadas actualmente en nuestro país.

Cystic echinococcosis is a zoonosis of parasitic origin with cosmopolitan distribution. In our country it continues to be an endemic disease, affecting mainly small population centers and poor rural areas related to sheep production. Control plans require a holistic approach, with the participation of different institutions, professionals and especially the community. Regional cooperation seeks to monitor the progress of the disease and focus action measures on four axes, defined according to the most common points of intervention to break the transmission cycle and consequently reduce the incidence and prevalence of the disease. This review used literature obtained from different databases, virtual libraries and regional and local websites with the aim of describing the main control, surveillance and prevention strategies currently applied in our country.

Pregnancy after perinatal loss: A meta-ethnography from a women's perspective.

OBJECTIVE: This study uses a meta-ethnography to synthesize qualitative research on the experiences of women during pregnancies after one or more perinatal losses. DESIGN: This interpretive meta-ethnography followed the Noblit and Hare approach and the eMERGe Meta-ethnography Reporting Guidance. Manual searches and a comprehensive systematic search were conducted in Pubmed, Scopus, Cinahl, Web of Science, and Psycinfo. Eleven studies met the research objective and inclusion criteria. RESULTS: After reciprocal and refutational translations, the metaphor "The rainbow in the storm" and the following three themes emerged: (i) Between ambivalent feelings; (ii) being careful in the new pregnancy; and (iii) leaning on others. CERQual assessment showed that the results are (highly) reasonable representations of the phenomenon of interest. CONCLUSIONS: Most women experienced their subsequent pregnancy with ambivalent feelings and needed to reduce expectations, continuously monitor the pregnancy's viability, and eliminate risky behavior to protect themselves. Understanding and recognition by others is needed and appreciated. IMPLICATIONS FOR PRACTICE: Nurses and midwives play a crucial role in subsequent pregnancies and need to establish a care communion and ethical care during their encounters with affected women whose specific needs need to be incorporated into the guidelines and training curricula of care professionals to equip them with the necessary gender and cultural competences.

Effectiveness of physical therapy interventions in women with dyspareunia: a systematic review and meta-analysis.

BACKGROUND: Dyspareunia is defined as the occurrence of pain during or after sexual intercourse, which directly affects physical, sexual, and mental health. This condition can lead to depression, anxiety, and low self-esteem in women who experience it. OBJECTIVES: The aim of this research was to evaluate the effectiveness of physical therapy interventions for the treatment of female dyspareunia. DESIGN: A systematic review and meta-analysis was conducted. METHOD: Search of publications was conducted in Scopus, Medline, Pubmed, Cinahl and Web of Science. Treatment effects were defined as standardized mean difference and their 95% confidence intervals. Statistical heterogeneity was assessed using Crohan's Q test and quantified using the I2 index. RESULTS: Of the 19 articles selected, six applied multimodal physiotherapy treatments; five, electrotherapy; three, Thiele's massage; two, interdisciplinary interventions or pelvic floor muscle training; and one, extracorporeal shockwave therapy. The meta-analysis showed significant results for the variables pain and quality of life with the interventions based on electrotherapy and electrotherapy combined with pelvic floor muscle training. These interventions did not show significant results for the improvement of sexual function. CONCLUSIONS: Physiotherapy techniques are effective and procedures have been identified with reliable results in improving pain and quality of life in patients with dyspareunia. One of the most important aspects is the strengthening of the perineal musculature and the application of Transcutaneous Electrical Nerve Stimulation. Furthermore, manual trigger point release therapy and Thiele massage, optimize and guarantee the reduction of pain intensity. PROSPERO REGISTRATION: CRD42021236155.

Yoga-based interventions may reduce anxiety symptoms in anxiety disorders and depression symptoms in depressive disorders: a systematic review with meta-analysis and meta-regression.

OBJECTIVE: To summarise the effect of mind-body exercises on anxiety and depression symptoms in adults with anxiety or depressive disorders. DESIGN: Systematic review with meta-analysis and meta-regression. DATA SOURCES: Five electronic databases were searched from inception to July 2022. Manual searches were conducted to explore clinical trial protocols, secondary analyses of clinical trials and related systematic reviews. ELIGIBILITY CRITERIA: Randomised clinical trials evaluating qigong, tai chi or yoga styles with anxiety or depression symptoms as the outcomes were included. No intervention, waitlist or active controls were considered as control groups. The risk of bias and the certainty of the evidence were assessed. Meta-analyses, meta-regressions and sensitivity analyses were performed. RESULTS: 23 studies, comprising 22 different samples (n=1420), were included. Overall, meta-analyses showed yoga interventions were superior to controls in reducing anxiety symptoms in anxiety disorders. Furthermore, yoga-based interventions decreased depression symptoms in depressive disorders after conducting sensitivity analyses. No differences between groups were found in the rest of the comparisons. However, the certainty of the evidence was judged as very low for all outcomes due to concerns of high risk of bias, indirectness of the evidence, inconsistency and imprecision of the results. In addition, there was marked heterogeneity among yoga-based interventions and self-reported tools used to evaluate the outcomes of interest. CONCLUSION: Although yoga-based interventions may help to improve mental health in adults diagnosed with anxiety or depressive disorders, methodological improvements are needed to advance the quality of clinical trials in this field.

Supplementation with a New Standardized Extract of Green and Black Tea Exerts Antiadipogenic Effects and Prevents Insulin Resistance in Mice with Metabolic Syndrome.

Insulin resistance is one of the main characteristics of metabolic syndrome (MetS) and the main cause of the development of type II diabetes. The high prevalence of this syndrome in recent decades has made it necessary to search for preventive and therapeutic agents, ideally of natural origin, with fewer side effects than conventional pharmacological treatments. Tea is widely known for its medicinal properties, including beneficial effects on weight management and insulin resistance. The aim of this study was to analyze whether a standardized extract of green and black tea (ADM® Complex Tea Extract (CTE)) prevents the development of insulin resistance in mice with MetS. For this purpose, C57BL6/J mice were fed for 20 weeks with a standard diet (Chow), a diet with 56% kcal from fat and sugar (HFHS) or an HFHS diet supplemented with 1.6% CTE. CTE supplementation reduced body weight gain, adiposity and circulating leptin levels. Likewise, CTE also exerted lipolytic and antiadipogenic effects in 3T3-L1 adipocyte cultures and in the C. elegans model. Regarding insulin resistance, CTE supplementation significantly increased plasma adiponectin concentrations and reduced the circulating levels of insulin and the HOMA-IR. Incubation of liver, gastrocnemius muscle and retroperitoneal adipose tissue explants with insulin increased the pAkt/Akt ratio in mice fed with Chow and HFHS + CTE but not in those fed only with HFHS. The greater activation of the PI3K/Akt pathway in response to insulin in mice supplemented with CTE was associated with a decrease in the expression of the proinflammatory markers Mcp-1, IL-6, IL-1ß or Tnf-α and with an overexpression of the antioxidant enzymes Sod-1, Gpx-3, Ho-1 and Gsr in these tissues. Moreover, in skeletal muscle, mice treated with CTE showed increased mRNA levels of the aryl hydrocarbon receptor (Ahr), Arnt and Nrf2, suggesting that the CTE's insulin-sensitizing effects could be the result of the activation of this pathway. In conclusion, supplementation with the standardized extract of green and black tea CTE reduces body weight gain, exerts lipolytic and antiadipogenic effects and reduces insulin resistance in mice with MetS through its anti-inflammatory and antioxidant effects.

Neuropharmacological Effects in Animal Models and HPLC-Phytochemical Profiling of Byrsonima crassifolia (L.) Kunth Bark Extracts.

B. crassifolia is a species that grows in various areas of Latin America. It was known to be useful for the treatment of different human ailments. The present work evaluated the neuropharmacological and analgesic effects of hydroalcoholic and dichloromethane extracts of B. crassifolia. The effect on the central nervous system (CNS) of both extracts obtained from bark, administered by the intraperitoneal route in mice, was evaluated by different tests: spontaneous motor activity, hole-board, motor coordination, pentobarbital induced hypnosis, and rectal temperature. Analgesic activity was evaluated using a hot plate test. Phytochemical analysis was performed by high-performance liquid chromatography (HPLC) using reversed-phase and gradient of elution. The hydroalcoholic extract (dose 0.5 g dry plant/kg weigh) administration caused an important reduction of the head-dipping response in the hole board test. A decrease in spontaneous motor activity test and a disturbance of motor coordination in the rotarod test was observed. The hydroalcoholic extract produced a significant prolongation of pentobarbital induced sleeping time. This extract prevented hot plate test induced nociception. The phytochemical analysis revealed the presence of catechin, epicatechin, and procyanidin B12. Therefore, this study revealed that the hydroalcoholic extract of B. crassifolia possesses analgesic and sedative CNS activity.

Potential of plant extracts in targeting SARS-CoV-2 main protease: an in vitro and in silico study.

The deaths caused by the covid-19 pandemic have recently decreased due to a worldwide effort in vaccination campaigns. However, even vaccinated people can develop a severe form of the disease that requires ICU admission. As a result, the search for antiviral drugs to treat these severe cases has become a necessity. In this context, natural products are an interesting alternative to synthetic medicines used in drug repositioning, as they have been consumed for a long time through traditional medicine. Many natural compounds found in plant extracts have already been shown to be effective in treating viral and bacterial diseases, making them possible hits to exploit against covid-19. The objective of this work was to evaluate the antiviral activity of different plant extracts available in the library of natural products of the Universidade Estadual de Maringá, by inhibiting the SARS-CoV-2 main protease (Mpro), and by preventing viral infection in a cellular model. As a result, the extract of Cytinus hypocistis, obtained by ultrasound, showed a Mpro inhibition capacity greater than 90%. In the infection model assays using Vero cells, an inhibition of 99.6% was observed, with a selectivity index of 42.7. The in silico molecular docking simulations using the extract compounds against Mpro, suggested Tellimagrandin II as the component of C. hypocistis extract most likely to inhibit the viral enzyme. These results demonstrate the potential of C. hypocistis extract as a promising source of natural compounds with antiviral activity against covid-19.Communicated by Ramaswamy H. Sarma.

Efficacy of Dry Needling for Chronic Low Back Pain: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Objective: To evaluate the current evidence of the effectiveness of dry needling in patients with chronic low back pain (LBP). Methods: PubMed, Medline, ScienceDirect, Web of Science, CINAHL and PEDro databases were searched until 2020. Study selection: Randomised controlled trials (RCTs) that used dry needling as the main treatment and which included participants diagnosed with chronic LBP. Data extraction: Two reviewers independently screened articles, scored methodologic quality, and extracted data. The primary outcomes were pain intensity and functional disability at post-intervention and follow-up. Results: A total of 8 RCTs involving 414 patients were included in the meta-analysis. All trials examined the efficacy of DN in patients with chronic LBP. Results suggested that compared with other treatments, dry needling combined was more effective in alleviating the pain intensity of LBP post-intervention (standardised mean difference [SMD], -0.42; 95% confidence interval [CI], -0.79 to -0.05; P = .03) and at short- term (SMD -0.99, 95% CI -1.61 to -0.37, P = .002). Conclusion: Current evidence showed that dry needling, especially if associated with other therapies, could be recommended to relieve the pain intensity of LBP at post-intervention and at short-term follow up. There is no evidence that dry needling alone or in combination improves disability at post-immediate or at short-term follow up. Registration: This review was registered on PROSPERO (PROSPERO CRD42020215781) and was aligned with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting systematic reviews that evaluate healthcare interventions.

Antiviral activity of Cenostigma pluviosum var. peltophoroides extract and fractions against SARS-CoV-2.

Few extracts of plant species from the Brazilian flora have been validated from a pharmacological and clinical point of view, and it is important to determine whether their traditional use is proven by pharmacological effects. Cenostigma pluviosum var. peltophoroides is one of those plants, which belongs to the Fabaceae family that is widely used in traditional medicine and is very rich in tannins. Due to the lack of effective drugs to treat severe cases of Covid-19, the main protease of SARS-CoV-2 (Mpro) becomes an attractive target in the research for new antivirals since this enzyme is crucial for virus replication and does not have homologs in humans. This study aimed to prospect inhibitor candidates among the compounds from C. pluviosum extract, by virtual screening simulations using SARS-CoV-2 Mpro as target. Experimental validation was made by inhibitory proteolytic assays of recombinant Mpro and by antiviral activity with infected Vero cells. Docking simulations identify four compounds with potential inhibitory activity of Mpro present in the extract. The compound pentagalloylglucose showed the best result in proteolytic kinetics experiments, with suppression of recombinant Mpro activity by approximately 60%. However, in experiments with infected cells ethyl acetate fraction and sub-fractions, F2 and F4 of C. pluviosum extract performed better than pentagalloylglucose, reaching close to 100% of antiviral activity. The prominent activity of the extract fractions in infected cells may be a result of a synergistic effect from the different hydrolyzable tannins present, performing simultaneous action on Mpro and other targets from SARS-CoV-2 and host.Communicated by Ramaswamy H. Sarma.

NADES blend for bioactive coating design as a sustainable strategy for postharvest control.

Bioactive functional coatings constitute a trendy topic due to they reduce postharvest fruit losses worldwide. Also, they could be carriers of biocompounds providing health benefits to the consumer. In this work, an innovative natural bioactive coating based on Natural Deep Eutectic Solvents (NADES) and Larrea divaricata extract was optimized by mixture-mixture design for the management of postharvest diseases caused by Monilinia fructicola. A NADES composed of lactic acid-glucose-water (LGH) for phenolic extraction from L. divaricata was optimized by a Simplex Lattice design and response surface methodology (RSM).Then, a d-optimal mixture-mixture design was carried out in order to optimize the bioactive coating composition, being the optimal proportion of 0.7 L. divaricata-LGH extract and 0.3 NADES plasticizer (composed by glycerol, citric acid and water). The optimal biocoating achieved an in vitro antimicrobial activity of 72 % against M. fructicola. Interestingly, NADES plasticizer improves the biocoating functionality, creating a smooth and uniform surface.

Dietary supplementation with chia polyphenols alleviates oxidative stress and improves egg nutritional quality in Japanese quails under heat stress.

Heat stress in poultry is a major concern, especially in regions with hot summers and scarce cooling infrastructure. Dietary supplementation with antioxidants, such as polyphenols, has risen as a strategy to mitigate the physiological consequences of heat stress. A by-product of the extraction of oil from chia seeds, which is discarded if not used, could be a possible source of polyphenols. The aim of the present study was to evaluate the effects of dietary supplementation with polyphenols from defatted chia seed cake on the general performance, and oxidative status of Japanese quail exposed to heat stress. Furthermore, productive performance, egg quality and yolk fatty acid composition were also assessed. A total of 36 females (96 days of age) were randomly assigned to different diets: BASAL (control), LDCP (low dose of chia polyphenols), or HDCP (high dose of chia polyphenols). Half the animals in each diet group were exposed to 34 °C for 9 h a day (Heat Stress; HS), while the other half remained at the standard 24 °C (No Heat Stress; NHS). After 23 days of experimental conditions, animals under HS showed higher body temperatures and time spent panting, but lower egg laying rate. Moreover, HS modulated the activity of catalase and glutathione peroxidase enzymes, increasing lipid peroxidation in serum and liver; and increased saturated fatty acids in egg yolk. Supplementation with chia polyphenols helped to mitigate the HS effects, especially on glutathione peroxidase activity, decreasing lipid peroxidation. In addition, supplementation with HDCP showed the highest proportion of polyunsaturated fatty acids in liver and egg yolk. In conclusion, the use of defatted chia seed cake could represent a sustainable strategy to mitigate heat stress effects on Japanese quail, due to its capacity to decrease oxidative stress and improve the nutritional quality of egg, while decreasing the amount of waste generated by the food industry.

Associations between hair trace mineral concentrations and the occurrence of treponeme-associated hoof disease in elk (Cervus canadensis).

BACKGROUND: Trace minerals are important for animal health. Mineral deficiency or excess can negatively affect immune function, wound healing, and hoof health in domestic livestock, but normal concentrations and health impairment associated with mineral imbalances in wild animals are poorly understood. Treponeme-associated hoof disease (TAHD) is an emerging disease of free-ranging elk (Cervus canadensis) in the U.S. Pacific Northwest. Selenium and copper levels identified in a small number of elk from areas where TAHD is established (i.e., southwestern Washington) suggested a mineral deficiency may have increased susceptibility to TAHD. Our objectives were to determine trace mineral concentrations using hair from elk originating in TAHD affected areas of Washington, California, Idaho, and Oregon and assess their associations with the occurrence of the disease. RESULTS: We identified limited associations between TAHD occurrence and severity with hair mineral concentrations in 72 free-ranging elk, using Firth's logistic regression and multinomial regression models. We found consistent support for a priori hypotheses that selenium concentration, an important mineral for hoof health, is inversely associated with the occurrence of TAHD. Less consistent support was observed for effects of other minerals previously associated with hoof health (e.g., copper or zinc) or increased disease risk from potential toxicants. CONCLUSION: Trace mineral analysis of hair is a non-invasive sampling technique that offers feasibility in storage and collection from live animals and carcasses. For some minerals, levels in hair correlate with visceral organs that are challenging to obtain. Our study using hair collected opportunistically from elk feet submitted for diagnostic investigations provides a modest reference of hair mineral levels in elk from the U.S. Pacific Northwest that may be useful in future determination of reference ranges. Although our results revealed high variability in mineral concentrations between elk, consistent relationship of possibly low selenium levels and TAHD suggest that further investigations are warranted.

Mind-body practices for cancer-related symptoms management: an overview of systematic reviews including one hundred twenty-nine meta-analyses.

PURPOSE: Mind-body practices such as qigong, tai chi, or yoga combine physical movements, deep breathing, and meditation techniques aiming to improve how people self-care. Our purpose was to develop an overview of systematic reviews to summarize the available evidence on the effectiveness of mind-body practices for cancer-related symptoms management. METHODS: CINAHL, Embase, PsycINFO, PubMed, and the Cochrane Library were used to search systematic reviews with meta-analysis from inception until March 2022. Cancer-related symptoms such as fatigue, pain, psychological measures, and overall quality of life were chosen as outcomes of interest. The methodological quality of each systematic review was assessed using AMSTAR 2. Citation matrices were developed, and the corrected covered area was calculated to explore the potential primary study overlap. RESULTS: A total of 38 systematic reviews comprising 134 distinct primary studies and 129 separate meta-analyses were included. The items of AMSTAR 2 regarding the review protocol, the reasons to choose a specific research design, and the provision of a list of studies that justify their exclusion were scarcely performed. The primary study overlap was moderate for qigong trials and high for both tai chi and yoga trials. Mainly, we found that qigong showed promising effects to reduce fatigue. Tai chi produced positive effects in reducing anxiety. Yoga improved anxiety, depression, distress, stress, and overall quality of life. Finally, the effects of mind-body practices on pain were inconsistent. CONCLUSIONS: Qigong, tai chi, and yoga could be effective approaches to relief cancer-related symptoms in adults with different cancer diagnoses.

Moral experiences in caring for voluntary pregnancy losses: A meta-ethnography.

Voluntary abortions are relatively frequent and their care is complex due to the social stigma that surrounds these losses. This interpretive meta-ethnography of 11 original qualitative articles aims to synthesize the moral experiences of nurses and midwives who cared for women and couples that decided to abort or terminate the pregnancy due to foetal abnormalities. Lines of argument synthesis emerged after reciprocal and refutational translations, together with the metaphor, 'Going with the flow or swimming against the tide'. Caring in these situations was an ethical dilemma when a conflict existed between their professional duty and their moral principles. In these instances, care was associated with a significant emotional cost. They did not feel sufficiently prepared or with adequate resources, which favoured avoidance behaviours. However, the feeling of professional duty was stronger than their prejudices, and they became engaged in caring. These results could improve knowledge, clinical practice and education, being a (highly) reasonable representation of the phenomenon of interest.
