RESUMEN

Chronodisruption, commonly displayed by people living with obesity (PLO), is linked to colonic microbiota dysbiosis, and may increase the risk of many chronic non-communicable diseases, whereas dietary interventions-called chrononutrition may mitigate it. We evaluated the in vitro effects of spent coffee grounds (SCG), and their antioxidant dietary fiber (SCG-DF) on the colonic microbiota of an obese donor displaying dysbiosis and chronodisruption. Basal microbiota pattern was associated with an increased risk of non-communicable chronic diseases. Both samples decrease species richness and increase microbiota diversity (p < 0.05; Chao and Shannon index, respectively), positively enhancing Firmicutes/Bacteroidetes index (SCG, p < 0.04; SCG-DF, p < 0.02). SCG and SCG-DF modulated the microbiota, but SCG-DF induced greater changes, significantly increasing. p_Actonobacterias (SCG p < 0.04; SCG-DF, p < 0.02), and reducing g_Alistipes; s_putredinis, g_Prevotella;s_copri. The highest increase was displayed by p_Proteobacteria (f_Desulfovibrionaceae and f_Alcanigenaceae, p < 0.05), while g_Haemophilus; s_parainfluenzae decreased (p < 0.05). However, neither SCG nor SCG-DF modulated g_Alistipes (evening-type colonic microbial marker) beneficially. SCG and SCG-DF reduced (p < 0.05) g_Lachnospira, a microbial evening-type marker, among other microbial populations, of an obese donor displaying chronodisruption and dysbiosis. SCG and SCG-DF displayed a prebiotic effect with the potential to mitigate diseases linked to chronodisruption.

RESUMEN

Synsepalum dulcificum (Richardella dulcifica) is a berry fruit from West Africa with the ability to convert the sour taste into a sweet taste, and for this reason, the fruit is also known as the "miracle berry" (MB). The red and bright berry is rich in terpenoids. The fruit's pulp and skin contain mainly phenolic compounds and flavonoids, which correlate with their antioxidant activity. Different polar extracts have been described to inhibit cell proliferation and transformation of cancer cell lines in vitro. In addition, MB has been shown to ameliorate insulin resistance in a preclinical model of diabetes induced by a chow diet enriched in fructose. Herein, we have compared the biological activities of three supercritical extracts obtained from the seed-a subproduct of the fruit-and one supercritical extract obtained from the pulp and the skin of MB. The four extracts have been characterized in terms of total polyphenols content. Moreover, the antioxidant, anti-inflammatory, hypo-lipidemic, and inhibition of colorectal cancer cell bioenergetics have been compared. Non-polar supercritical extracts from the seed are the ones with the highest effects on the inhibition of bioenergetic of colorectal (CRC) cancer cells. At the molecular level, the effects on cell bioenergetics seems to be related to the inhibition of main drivers of the de novo lipogenesis, such as the sterol regulatory element binding transcription factor (SREBF1) and downstream molecular targets fatty acid synthase (FASN) and stearoyl coenzyme desaturase 1 (SCD1). As metabolic reprograming is considered as one of the hallmarks of cancer, natural extracts from plants may provide complementary approaches in the treatment of cancer. Herein, for the first time, supercritical extracts from MB have been obtained, where the seed, a by-product of the fruit, seems to be rich in antitumor bioactive compounds. Based on these results, supercritical extracts from the seed merit further research to be proposed as co-adjuvants in the treatment of cancer.

RESUMEN

INTRODUCTION: Gait disorders are a major cause of disability and reduced health-related quality of life in people with multiple sclerosis (pwMS). Dry needling (DN) has demonstrated positive results to improve gait parameters in patients with stroke. The main aim of this study was to evaluate the effect of a single session of DN in the gait performance of pwMS. METHODS: A double-blind parallel randomized sham-controlled pilot trial was conducted. Study participants received a single session of active DN or sham DN in the gastrocnemius medialis muscle. Pre-treatment and immediately post-treatment measurements were taken, as well as at one and four weeks after the intervention. Outcomes related to gait performance (Timed 25-Foot Walk), self-perceived walking capacity (Multiple Sclerosis Walking Scale), risk of falls (Timed Up and Go test), disability level (Expanded Disability Status Score) and quality of life (Multiple Sclerosis Quality of Life-54 questionnaire and Analogic Quality of Life scale) were evaluated. RESULTS: 18 patients who had multiple sclerosis participated in the study. The group who received active DN showed within-group significant statistical differences immediately after treatment for gait performance (p = 0.008) and risk of falls (p = 0.008), as well as for self-perceived walking capacity at one week (p = 0.017) and four weeks (p = 0.011) and quality of life at four weeks (p = 0.014). Regarding the comparison between groups, only significant results were obtained in the physical domain of the quality of life at four weeks (p = 0.014). CONCLUSIONS: DN seems to be a promising therapeutic tool for the treatment of gait disorders in pwMS. However, when results were compared with sham DN, no differences were found.

RESUMEN

BACKGROUND AND OBJECTIVES: Complicated grief (CG) is severe, prolonged (>12 months) grieving. Complicated grief disproportionately affects older adults and is associated with negative physical/psychological effects. Although treatment options exist, those which do are time-intensive. We report on a randomized clinical trial (RCT) which examined whether accelerated resolution therapy (ART), a novel mind-body therapy, is effective in treating CG, post-traumatic stress disorder (PTSD), and depression among hospice informal caregivers. RESEARCH DESIGN AND METHODS: Prospective 2 group, wait-listed RCT. All participants were scheduled to receive 4 ART sessions. INCLUSION: ≥60 years, inventory of CG >25, and PTSD checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition >33 or Psychiatric Diagnostic Screen Questionnaire PTSD subscale >5. EXCLUSION: Major psychiatric disorder, other current psychotherapy treatment. Depression was measured by the Center for Epidemiologic Studies Depression. RESULTS: Mean (standard deviation [SD]) age of 54 participants was 68.7 (7.2) years, 85% female, and 93% white. Participants assigned to ART reported significantly greater mean (SD) CG reduction (-22.8 [10.3]) versus Wait-list participants (-4.3 [6.0]). Within-participant effect sizes (ESs) for change from baseline to 8-week post-treatment were CG (ES = 1.96 (95% confidence interval [CI]: 1.45-2.47; P < .0001), PTSD (ES = 2.40 [95% CI: 1.79-3.00]; P < .0001), depression (ES = 1.63 [95% CI: 1.18-2.08; P < .0001). Treatment effects did not substantially differ by baseline symptom levels. DISCUSSION AND IMPLICATIONS: Results suggests that ART presents an effective and less time-intensive intervention for CG in older adults. However, it should undergo further effectiveness testing in a larger, more diverse clinical trial with a focus on determining physiological or behavioral mechanisms of action.

RESUMEN

INTRODUCTION: The United States has been actively involved in major armed conflicts over the last 15 years. As a result, a significant proportion of active duty service personnel and returning veterans have endured combat, putting them at risk for developing post-traumatic stress disorder (PTSD), a disabling disorder that may occur after exposure to a traumatic event. Current therapies often require long-term, time-intensive and costly commitment from the patient and have variable degrees of success. There remains an ongoing need for better therapies, including complementary medicine approaches that can effectively reduce PTSD symptoms. While anecdotal evidence suggests that routine practice of Brazilian Jiu Jitsu (BJJ) can reduce symptoms of PTSD, there have been no formal studies to address this. MATERIALS AND METHODS: This study was approved by the University of South Florida Institutional Review Board (#PRO00019430). Male US active duty service members and veterans from the Tampa area participated in a 5-month (40 sessions) BJJ training program. Before beginning and again midway through and upon completion of training the participants completed several validated self-report measures that addressed symptoms of PTSD and other co-morbid conditions. Effect size and 95% confidence intervals were determined using a within-person single-group pretest-posttest design. RESULTS: Study participants demonstrated clinically meaningful improvements in their PTSD symptoms as well as decreased symptoms of major depressive disorder, generalized anxiety and decreased alcohol use; effect sizes varied from 0.80 to 1.85. CONCLUSIONS: The results from this first-of-kind pilot study suggest that including BJJ as a complementary treatment to standard therapy for PTSD may be of value. It will be necessary to validate these promising results with a larger subject cohort and a more rigorous experimental design before routinely recommending this complementary therapy.

RESUMEN

In this study, the supercritical CO2-based extraction approach was used from the green technologies to extract Oregano oil (Origanum vulgare L.). A Taguchi experimental design was applied to evaluate the effect of pressure, temperature and ethanol as co-solvent. High yield of oregano oil (13.40%) was obtained at 40 °C, 100 bar and 8 g min-1 of co-solvent flow. Fatty acids profile include α-linolenic, palmitic, oleic and linoleic that contribute to 70.9-76.8% of total fatty acids. Volatile compounds including carvacrol (29.99%), heneicosane (8.21%), nonacosane (11.78%), docosane (7.18%), borneol (4.35%) and thymol (4.51%) were the main compounds identified. Antimicrobial activity assays showed that extracts obtained at 40 °C were highly efficient against S. aureus, E. coli, and C. albicans. Highest antioxidant activities on DPPH and FRAP assays were reached under 8 g min-1 of co-solvent flow (6.08 and 6.89 µmol TE g-1 extract, respectively). On the other hand, antioxidant activity (35.76 µmol TE g-1) on ABTS assay was improved at 40 °C, 100 bar, and 4 g min-1 of co-solvent flow.

RESUMEN

Arthrospira platensis was used to obtain functional extracts through supercritical carbon dioxide extraction (SFE-CO2). Pressure (P), temperature (T), co-solvent (CX), static extraction (SX), dispersant (Di) and dynamic extraction (DX) were evaluated as process parameters through a Plackett-Burman design. The maximum extract yield obtained was 7.48 ± 0.15% w/w. The maximum contents of bioactive metabolites in extracts were 0.69 ± 0.09 µg/g of riboflavin, 5.49 ± 0.10 µg/g of α-tocopherol, 524.46 ± 0.10 µg/g of ß-carotene, 1.44 ± 0.10 µg/g of lutein and 32.11 ± 0.12 mg/g of fatty acids with 39.38% of palmitic acid, 20.63% of linoleic acid and 30.27% of γ-linolenic acid. A. platensis extracts had an antioxidant activity of 76.47 ± 0.71 µg GAE/g by Folin-Ciocalteu assay, 0.52 ± 0.02, 0.40 ± 0.01 and 1.47 ± 0.02 µmol TE/g by DPPH, FRAP and TEAC assays, respectively. These extracts showed antimicrobial activity against Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922 and Candida albicans ATCC 10231. Overall, co-solvent was the most significant factor for all measured effects (p < 0.05). Arthrospira platensis represents a sustainable source of bioactive compounds through SFE using the following extraction parameters P: 450 bar, CX: 11 g/min, SX: 15 min, DX: 25 min, T: 60 °C and Di: 35 g.

RESUMEN

Bioactivity and functional properties of cyanobacterial extract mostly depends on process of extraction, temperature and solvent used (polar or non-polar). To evaluate these parameters a design of experiment (DOE; using a 2k design) was performed with Arthrospira platensis. Extraction process was optimized through microwave-assisted extraction considering solvent ratio, temperature and time of extraction with polar (PS) and non-polar (NPS). Maximum extract yield obtained was 4.32±0.25% and 5.26±0.11% (w/w) respectively for PS and NPS. Maximum content of bioactive metabolites in PS extracts were thiamine (846.57±14.12µg/g), riboflavin (101.09±1.63µg/g), C-phycocyanin (2.28±0.10µg/g) and A-phycocyanin (4.11±0.03µg/g), while for NPS extracts were α-tocopherol (37.86±0.78µg/g), ß-carotene (123.64±1.45µg/g) and 19.44±0.21mg/g of fatty acids. A. platensis PS extracts showed high antimicrobial activity and PS extracts had antioxidant activity of 0.79±0.12µmolTE/g for FRAP assay, while for NPS extracts 1.03±0.08µmol α-TE/g for FRAP assay.

RESUMEN

BACKGROUND: Posttraumatic stress disorder (PTSD) is prevalent in both homeless and nonhomeless veterans. PURPOSE: To examine unique characteristics of being homeless that may influence PTSD treatment completion and clinical success. METHODS: Twenty-three veterans who were homeless and residing in a homeless shelter, along with 94 veterans from the community, were enrolled to receive one to five sessions of Accelerated Resolution Therapy (ART), an emerging trauma-focused therapy for symptoms of PTSD. Rates of treatment completion with ART and acute and 6-month change in symptoms of PTSD were compared in an observational (nonrandomized) manner by housing status. FINDINGS: Compared to veterans recruited from the community, veterans residing in the homeless shelter were older and presented with more extensive psychopathology yet had less combat exposure while being more likely to have experienced sexual assault. Rates of treatment completion were 52.2% (12 of 23) among homeless veterans compared to 81.9% (77 of 94) among veterans from the community (p = .005). Among treatment completers, both groups received an average of four sessions of ART. Reduction of symptoms of PTSD was substantial and nonsignificantly greater among homeless veterans vs. those treated from the community (p = .14), as were comorbidity reductions in depression, anxiety, sleep quality, pain, and improved quality of life. Results at 6-month posttreatment follow-up were similar. CONCLUSIONS: Although limited by small sample size and a nonrandomized design, ART appears to be an effective, brief treatment for symptoms of PTSD among veterans residing in a homeless shelter. However, development of effective strategies to maximize treatment completion among homeless veterans is needed.

RESUMEN

Recent outcomes for Cognitive Processing Therapy (CPT) and Prolonged Exposure (PE) therapy indicate that as many as 60-72% of patients retain their PTSD diagnosis after treatment with CPT or PE. One emerging therapy with the potential to augment existing trauma focused therapies is Accelerated Resolution Therapy (ART). ART is currently being used along with evidence based approaches at Fort Belvoir Community Hospital and by report has been both positive for clients as well as less taxing on professionals trained in ART. The following is an in-practice theoretical comparison of CPT, EMDR and ART with case examples from Fort Belvoir Community Hospital. While all three approaches share common elements and interventions, ART distinguishes itself through emphasis on the rescripting of traumatic events and the brevity of the intervention. While these case reports are not part of a formal study, they suggest that ART has the potential to augment and enhance the current delivery methods of mental health care in military environments.

RESUMEN

In this study, a series of novel C-28 esters and amides derivatives of hederagenin (He) were designed and synthesized in attempt to develop potent antitumor agents. Their structures were confirmed by MS, IR, (1)H NMR and (13)C NMR spectroscopic analyses and their cytotoxic activities were screened in SRB assays using a panel of six human cancer cell lines. Although most of the compounds displayed moderate to high levels of cytotoxic activity they were all more potent than the natural product He. The most active compounds had either an ethylpyrimidinyl (27) or an ethylpyrrolidinyl (28) substituent, with EC50 in the range of 1.1-6.5 µM for six human cancer cell lines. Notably, this corresponds to an approximately 30-fold times greater potency than He.

RESUMEN

Blakiella bartsiifolia (S.F. Blake), an endemic and rare high altitude plant of the northern Andes, appears well adapted to the prevailing harsh environment owing in part to a thick glandular trichome cover. From foliar exudates, two new clerodanes, 15,16-epoxy-2-hydroxy-3,13(16),14-clerodatrien-20-oic acid (bartsiifolic acid) (2) and Z-15,16-dihydroxy-3,13-clerodien-20-oic acid (barthydrolic acid) (3), were isolated in addition to the known junceic acid (1). In addition, three new alicyclic furanoditerpenes: 1,20-epoxy-1,3(20),6(E),10(E),14-phytapentaen-18-methyl-19-oic acid (blakielic acid) (4), 1,20-epoxy- 1,3(20),10(E),14-phytapentaen-18-methyl-19-oic acid (blakifolic acid) (5) and 1,20-epoxy-1,3(20),6,14-phytatetraen-19-methyl-18-oic acid (dihydrocentipedic acid) (6) were obtained in minor quantity. Seed germination and plantlet growth bioassays on Allium cepa and Lactuca sativa to monitor bioactivity during isolation procedures revealed compounds 1-3 with substantial inhibition comparable with synthetic linuron.

RESUMEN

PURPOSE: CBM is an international Christian development organisation, committed to improving the quality of life of persons with disabilities in disadvantaged societies. CBM aims at achieving this in partnership with local organisations and in cooperation with stakeholders at regional and international levels. This article aims at sharing CBM's holistic approach for successful engagement in the work area of ear care, deafness, hard of hearing and deafblindness. METHODS: Review of CBM supporting documents, including strategies, position papers, technical guidelines, criteria of success and information related to partners, centres of excellence and model projects. RESULTS: Description of how partner programmes use participatory methods of planning and implementation, involving persons with disabilities and the community. Recommendations on how to develop national or sub-national strategies to impact the lives, and advocate with governments for the rights and inclusion, of persons with disabilities. CONCLUSIONS: CBM's holistic approach to work in the area of ear care; deafness; hard of hearing and deafblindness includes intervention at all levels of health care provision, Education, CBR and Audiological, Speech Therapy and other interdisciplinary services. This article presents CBM's core principles and shares specific strategic planning and results, together with lessons learnt while searching a sustainable engagement for field work. IMPLICATIONS FOR REHABILITATION: Rehabilitation, in its widest conception, should be approached as a multidisciplinary strategy, and developed in close cooperation with other local, national and international agencies. CBM is positioned in a strategic point from where it can play a key role in the facilitation of an international forum for agencies and stakeholders to reach a consensus to decrease the burden of ear disease and hearing loss, through early intervention and re/habilitation.

RESUMEN

OBJECTIVES: This article describes a new, brief exposure-based psychotherapy known as Accelerated Resolution Therapy (ART) that is currently being evaluated as a treatment for combat-related post-traumatic stress disorder (PTSD). METHODS: We describe a case report of an Army veteran with combat-related PTSD who was treated with 2 sessions of ART and experienced significant clinical improvement. We then discuss the theoretical basis and major components of the ART protocol, including use of lateral left-right eye movements, and differentiate ART with evidence-based psychotherapies currently endorsed by the Department of Defense and Veterans Administration. RESULTS: The number of military personnel who have served in the wars in Iraq and Afghanistan and are afflicted with PTSD is likely in the hundreds of thousands. The ART protocol, which is delivered in 2 to 5 sessions and without homework, uses the psychotherapeutic practices of imaginal exposure and imagery rescripting (IR) facilitated through sets of eye movements. In addition to its brevity, a novel component of ART is use of IR to "replace" negative imagery (and other sensations) with positive imagery. CONCLUSIONS: This theoretical description of ART and single case report provide a rationale for future formal evaluation of ART for treatment of military-related PTSD.

RESUMEN

OBJECTIVES: Therapies for post-traumatic stress disorder (PTSD) endorsed by the Department of Defense and Veterans Administration are relatively lengthy, costly, and yield variable success. We evaluated Accelerated Resolution Therapy (ART) for the treatment of combat-related psychological trauma. METHODS: A randomized controlled trial of ART versus an Attention Control (AC) regimen was conducted among 57 U.S. service members/veterans. After random assignment, those assigned to AC were offered crossover to ART, with 3-month follow-up on all participants. Self-report symptoms of PTSD and comorbidities were analyzed among study completers and by the intention-to-treat principle. RESULTS: Mean age was 41 ± 13 years with 19% female, 54% Army, and 68% with prior PTSD treatment. The ART was delivered in 3.7 ± 1.1 sessions with a 94% completion rate. Mean reductions in symptoms of PTSD, depression, anxiety, and trauma-related guilt were significantly greater (p < 0.001) with ART compared to AC. Favorable results for those treated with ART persisted at 3 months, including reduction in aggression (p < 0.0001). Adverse treatment-related events were rare and not serious. CONCLUSIONS: ART appears to be a safe and effective treatment for symptoms of combat-related PTSD, including refractory PTSD, and is delivered in significantly less time than therapies endorsed by the Department of Defense and Veterans Administration.

RESUMEN

BACKGROUND: Procedures for the evaluation of the origin and quality of ground and roasted coffee are constantly needed for the associated industry due to complexity of the related market. Conventional Fourier transform infrared (FTIR) spectroscopy can be used for detecting changes in functional groups of compounds, such as coffee. However, dispersion, reflection and non-homogeneity of the sample matrix can cause problems resulting in low spectral quality. On the other hand, sample preparation frequently takes place in a destructive way. To overcome these difficulties, in this work a photoacoustic cell has been adapted as a detector in a FTIR spectrophotometer to perform a study of roasted and ground coffee from three varieties of Coffea arabica grown by organic and conventional methods. RESULTS: Comparison between spectra of coffee recorded by FTIR-photoacoustic spectrometry (PAS) and by FTIR spectrophotometry showed a better resolution of the former method, which, aided by principal components analysis, allowed the identification of some absorption bands that allow the discrimination between organic and conventional coffee. CONCLUSION: The results obtained provide information about the spectral behavior of coffee powder which can be useful for establishing discrimination criteria. It has been demonstrated that FTIR-PAS can be a useful experimental tool for the characterization of coffee.

RESUMEN

Post-Traumatic Stress Disorder (PTSD) is a prevalent, disabling anxiety disorder. This prospective cohort study reports on a new exposure-based therapy known as Accelerated Resolution Therapy (ART(®)) that incorporates the use of eye movements administered in a brief treatment period (1-5 one-hour sessions within three weeks). Eighty adults aged 21-60 years with symptoms of PTSD were recruited from the Tampa Bay area. The ART-based psychotherapy was designed to minimize anxiety and body sensations associated with recall of traumatic memories and to replace distressing images with favorable ones. Participants' mean age was 40 years, 77% were female, and 29% were Hispanic. Participants underwent a median of three ART sessions, 66 of 80 (82.5%) completed treatment, and 54 of 66 (81.8%) provided 2-month follow-up data. Mean scores pre- and post-ART and at 2-month follow-up were: PTSD Checklist: 54.5 ± 12.2 vs. 31.2 ± 11.4 vs. 30.0 ± 12.4; Brief Symptom Inventory: 30.8 ± 14.6 vs. 10.1 ± 10.8 vs. 10.1 ± 12.1; Center for Epidemiologic Studies Depression Scale: 29.5 ± 10.9 vs. 11.8 ± 11.1 vs. 13.5 ± 12.1; Trauma Related Growth Inventory-Distress scale: 18.9 ± 4.1 vs. 7.4 ± 5.9 vs. 8.2 ± 5.9 (p < 0.0001 for all pre-ART vs. post-ART and 2-month comparisons). No serious adverse events were reported. ART appears to be a brief, safe, and effective treatment for symptoms of PTSD.
