RESUMO

BACKGROUND: In routine, Ayurveda practitioners prefer classical pharmaceutical form of herbal medicines in compare to modern extracts. OBJECTIVE: To explore the difference of efficiency between whole drug powder of Phyllanthus niruri plus root decoction of Sida cordifolia and modern extracts of the same in compared to placebo in patients of diabetic poly-neuropathy. MATERIAL AND METHODS: A randomized, partly-double-blinded, placebo-controlled trial evaluated the efficacy of two different pharmaceutical forms of herbal medicines over placebo in 90 patients (30 in each group) of diabetic sensory polyneuropathy for first three weeks period. After three weeks, active herbal medication groups were continued with their assigned medicaments for next 5 weeks period and all placebo-patients were randomized again into 2 groups of active medication and treated for next 8 weeks. Patients were assessed with Neuropathy Total Symptom Score 6 and sensation thresholds. RESULTS: Significant effect of both form of herbal medicines over placebo was found in aching pain [F (2, 49) = 6.79, p = 0.002], allodynia [F (2, 59) = 6.74, p = 0.002], burning pain [F (2, 82) = 14.66, p < 0.0001], numbness [F (2, 77) = 16.37, p < 0.0001] and pricking pain [F (2, 50) = 14.23, p < 0.0001]. After the 8 weeks period, no significant difference was identified between the effect of both the herbal treatment on aching pain (U = 220, p = 0.03), allodynia (U = 421.5, p = 0.29), burning pain (U = 881.5, p = 0.846), numbness (U = 778, p = 0.92) and pricking pain (U = 260, p = 0.15). CONCLUSION: Both herbal groups have significant effect to reduce NTSS-6 score in compare to placebo. No significant difference found between the effect of two different pharmaceutical forms of Phyllanthus niruri and S. cordifolia.

RESUMO

Índralupta is a disease characterized by patches of hair loss spread throughout the body and scalp. It can be considered alopecia areata according to conventional medical care. The present case report is on the effectiveness of shodhana (treatment in which aggravated doshas are expelled from the body) and shamana (treatment that pacifies the aggravated doshas) in the patient of índralupta. A patient 25 years old, had hair loss patches on the scalp and many other areas of the body. The patient took conventional modern medicine as well as ayurveda treatment but didn't get a satisfactory result. The patient was hospitalized and treated with vamana (medicated emesis), virechana (medicated purgation), basti (administration of medicine through procto-colonic route), raktamokshana (blood-letting), and nasya (medicine administered through nasal route) along with shamana treatment for more than 6 weeks. The hair eruption started from many patches of the scalp and whole body. In this case, regrowth of hair from hair follicles was evident within 15 days of treatment. The collected data of this study suggest that shodhana and shamana treatment can provide noteworthy relief in índralupta.

RESUMO

AIM: The effects of the COVID-19 pandemic on healthcare in Australia have yet to be fully determined. There are well documented decreases in the rates of screening and diagnostic testing for many cancers in 2020, with commensurate stage migration of cancers when they are eventually detected. We aimed to determine whether there was a decrease in the rate of prostate cancer (PC) screening and testing in Australia in 2020. METHOD: Data was extracted from the Department of Human Services (DHS) website for Medicare Benefits Schedule (MBS) item numbers for tests pertinent to detection of Prostate Cancer. This data is de-identified and publicly available. Data was analysed at both a national, and a state level. RESULTS: For 2020 nationwide the percentage change for prostate cancer testing was minor with 97% as many PSA tests, 99% as many prostate MRIs, and 105% as many prostate biopsies as the average for the preceding years. The differences were not significant (PSA tests p = 0.059 and prostate biopsies p = 0.109). The predicted values are fairly similar to both the average values for the preceding 5 years and the actual number of tests done in 2020. With exception of PSA tests in Victoria the actual number of tests performed was within the 95% Prediction Interval (performed: 167,426; predicted 171,194-196,699; p = 0.015). CONCLUSION: The current pandemic has had a widespread reach across Australia, with varying impact across each state and territory. Contrary to the trends across the world, our data suggest that during 2020 in Australia most areas remained unaffected in terms of prostate cancer testing excluding Victoria, which had statistically significant decrease in the number of PSA tests correlating with the extended lockdown that occurred in the state.

RESUMO

Epidemiologic surveillance has revealed decoupling of Coronavirus Disease 2019 (COVID-19) hospitalizations and deaths from case counts after emergence of the Omicron (B.1.1.529) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant globally. However, assessment of the relative severity of Omicron variant infections presents challenges because of differential acquired immune protection against Omicron and prior variants and because longer-term changes have occurred in testing and healthcare practices. Here we show that Omicron variant infections were associated with substantially reduced risk of progression to severe clinical outcomes relative to time-matched Delta (B.1.617.2) variant infections within a large, integrated healthcare system in Southern California. Adjusted hazard ratios (aHRs) for any hospital admission, symptomatic hospital admission, intensive care unit admission, mechanical ventilation and death comparing individuals with Omicron versus Delta variant infection were 0.59 (95% confidence interval: 0.51-0.69), 0.59 (0.51-0.68), 0.50 (0.29-0.87), 0.36 (0.18-0.72) and 0.21 (0.10-0.44), respectively. This reduced severity could not be explained by differential history of prior infection among individuals with Omicron or Delta variant infection and was starkest among individuals not previously vaccinated against COVID-19 (aHR = 0.40 (0.33-0.49) for any hospital admission and 0.14 (0.07-0.28) for death). Infections with the Omicron BA.2 subvariant were not associated with differential risk of severe outcomes in comparison to BA.1/BA.1.1 subvariant infections. Lower risk of severe clinical outcomes among individuals with Omicron variant infection should inform public health response amid establishment of the Omicron variant as the dominant SARS-CoV-2 lineage globally.

RESUMO

BACKGROUND: To examine changes in prostate cancer incidence and mortality rates, and 5-year relative survival, in relation to changes in the rate of prostate specific antigen (PSA) screening tests and the use of radical prostatectomy (RP) in the Australian population. METHODS: Prostate cancer stage-specific incidence rates, 5-year relative survival and mortality rates were estimated using New South Wales Cancer Registry data. PSA screening test rates and RP/Incidence ratios were estimated from Medicare Benefits Schedule claims data. We used multiple imputation to impute stage for cases with "unknown" stage at diagnosis. Annual percentage changes (APC) in rates were estimated using Joinpoint regression. RESULTS: Trends in the age-standardized incidence rates for localized disease largely mirrored the trends in PSA screening test rates, with a substantial 'spike' in the rates occurring in 1994, followed by a second 'spike' in 2008, and then a significant decrease from 2008 to 2015 (APC -6.7, 95% CI -8.2, -5.1). Increasing trends in incidence rates were observed for regional stage from the early 2000s, while decreasing or stable trends were observed for distant stage since 1993. The overall RP/Incidence ratio increased from 1998 to 2003 (APC 9.6, 95% CI 3.8, 15.6), then remained relatively stable to 2015. The overall 5-year relative survival for prostate cancer increased from 58.4% (95% CI: 55.0-61.7%) in 1981-1985 to 91.3% (95% CI: 90.5-92.1%) in 2011-2015. Prostate cancer mortality rates decreased from 1990 onwards (1990-2006: APC -1.7, 95% CI -2.1, -1.2; 2006-2017: APC -3.8, 95% CI -4.4, -3.1). CONCLUSIONS: Overall, there was a decrease in the incidence rate of localized prostate cancer after 2008, an increase in survival over time and a decrease in the mortality rate since the 1990s. This seems to indicate that the more conservative use of PSA screening tests in clinical practice since 2008 has not had a negative impact on population-wide prostate cancer outcomes.

RESUMO

OBJECTIVE: To determine whether the addition of inhaled methoxyflurane to periprostatic infiltration of local anaesthetic (PILA) during transrectal ultrasonography-guided prostate biopsies (TRUSBs) improved pain and other aspects of the experience. PATIENTS AND METHODS: We conducted a multicentre, placebo-controlled, double-blind, randomized phase 3 trial, involving 420 men undergoing their first TRUSB. The intervention was PILA plus a patient-controlled device containing either 3 mL methoxyflurane, or 3 mL 0.9% saline plus one drop of methoxyflurane to preserve blinding. The primary outcome was the pain score (0-10) reported by the participant after 15 min. Secondary outcomes included ratings of other aspects of the biopsy experience, willingness to undergo future biopsies, urologists' ratings, biopsy completion, and adverse events. RESULTS: The mean (SE) pain scores 15 min after TRUSB were 2.51 (0.22) in those assigned methoxyflurane vs 2.82 (0.22) for placebo (difference 0.31, 95% confidence interval [CI] -0.75 to 0.14; P = 0.18). Methoxyflurane was associated with better scores for discomfort (difference -0.48, 95% CI -0.92 to -0.03; P = 0.035, adjusted [adj.] P = 0.076), whole experience (difference -0.50, 95% CI -0.92 to -0.08; P = 0.021, adj. P = 0.053), and willingness to undergo repeat biopsies (odds ratio 1.67, 95% CI 1.12-2.49; P = 0.01) than placebo. Methoxyflurane resulted in higher scores for drowsiness (difference +1.64, 95% CI 1.21-2.07; P < 0.001, adj. P < 0.001) and dizziness (difference +1.78, 95% CI 1.31-2.24; P < 0.001, adj. P < 0.001) than placebo. There was no significant difference in the number of ≥ grade 3 adverse events. CONCLUSIONS: We found no evidence that methoxyflurane improved pain scores at 15 min, however, improvements were seen in patient-reported discomfort, overall experience, and willingness to undergo repeat biopsies.

RESUMO

INTRODUCTION: Active surveillance (AS) for patients with prostate cancer (PC) with low risk of PC death is an alternative to radical treatment. A major drawback of AS is the uncertainty whether a patient truly has low risk PC based on biopsy alone. Multiparametric MRI scan together with biopsy, appears useful in separating patients who need curative therapy from those for whom AS may be safe. Two small clinical trials have shown short-term high-dose vitamin D supplementation may prevent PC progression. There is no substantial evidence for its long-term safety and efficacy, hence its use in the care of men with PC on AS needs assessment. This protocol describes the ProsD clinical trial which aims to determine if oral high-dose vitamin D supplementation taken monthly for 2 years can prevent PC progression in cases with low-to-intermediate risk of progression. METHOD AND ANALYSIS: This is an Australian national multicentre, 2:1 double-blinded placebo-controlled phase II randomised controlled trial of monthly oral high-dose vitamin D supplementation (50 000 IU cholecalciferol), in men diagnosed with localised PC who have low-to-intermediate risk of disease progression and are being managed by AS. This trial will assess the feasibility, efficacy and safety of supplementing men with an initial oral loading dose of 500 000 IU cholecalciferol, followed by a monthly oral dose of 50 000 IU during the 24 months of AS. The primary trial outcome is the commencement of active therapy for clinical or non-clinical reason, within 2 years of AS. ETHICS AND DISSEMINATION: This trial is approved by Bellberry Ethics Committee (2016-06-459). All results will be reported in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ACTRN12616001707459.

RESUMO

BACKGROUND: Covalent Bruton's tyrosine kinase (BTK) inhibitors are efficacious in multiple B-cell malignancies, but patients discontinue these agents due to resistance and intolerance. We evaluated the safety and efficacy of pirtobrutinib (working name; formerly known as LOXO-305), a highly selective, reversible BTK inhibitor, in these patients. METHODS: Patients with previously treated B-cell malignancies were enrolled in a first-in-human, multicentre, open-label, phase 1/2 trial of the BTK inhibitor pirtobrutinib. The primary endpoint was the maximum tolerated dose (phase 1) and overall response rate (ORR; phase 2). This trial is registered with ClinicalTrials.gov, NCT03740529. FINDINGS: 323 patients were treated with pirtobrutinib across seven dose levels (25 mg, 50 mg, 100 mg, 150 mg, 200 mg, 250 mg, and 300 mg once per day) with linear dose-proportional exposures. No dose-limiting toxicities were observed and the maximum tolerated dose was not reached. The recommended phase 2 dose was 200 mg daily. Adverse events in at least 10% of 323 patients were fatigue (65 [20%]), diarrhoea (55 [17%]), and contusion (42 [13%]). The most common adverse event of grade 3 or higher was neutropenia (32 [10%]). There was no correlation between pirtobrutinib exposure and the frequency of grade 3 treatment-related adverse events. Grade 3 atrial fibrillation or flutter was not observed, and grade 3 haemorrhage was observed in one patient in the setting of mechanical trauma. Five (1%) patients discontinued treatment due to a treatment-related adverse event. In 121 efficacy evaluable patients with chronic lymphocytic leukaemia (CLL) or small lymphocytic lymphoma (SLL) treated with a previous covalent BTK inhibitor (median previous lines of treatment 4), the ORR with pirtobrutinib was 62% (95% CI 53-71). The ORR was similar in CLL patients with previous covalent BTK inhibitor resistance (53 [67%] of 79), covalent BTK inhibitor intolerance (22 [52%] of 42), BTK C481-mutant (17 [71%] of 24) and BTK wild-type (43 [66%] of 65) disease. In 52 efficacy evaluable patients with mantle cell lymphoma (MCL) previously treated with covalent BTK inhibitors, the ORR was 52% (95% CI 38-66). Of 117 patients with CLL, SLL, or MCL who responded, all but eight remain progression-free to date. INTERPRETATION: Pirtobrutinib was safe and active in multiple B-cell malignancies, including patients previously treated with covalent BTK inhibitors. Pirtobrutinib might address a growing unmet need for alternative therapies for these patients. FUNDING: Loxo Oncology.

RESUMO

Objective: The aim of this study was to evaluate the effects of Ayurvedic treatment on deceleration of the disease progress of nondialysis patients with stage IV or V chronic renal failure (CRF). Materials and Methods: A complex oral and proctocolonic Ayurvedic multiherbal medication was administered daily for 1 month to inpatients. Thereafter, patients were treated as outpatients with oral medication for additional 5 months. Four renal function tests (RFTs) were evaluated at various time points (TPs): (1) 6 months before baseline (TP -6), (2) at baseline (TP 0), and (3) after completion of 6 months of treatment (TP +6). Repeated-measures analysis of variance (ANOVA) with Greenhouse-Geisser correction and Friedman's ANOVA by ranks were used to analyze the RFTs. For post hoc tests, the Bonferroni correction was applied. Bias-corrected effect sizes (Hedges) for the treatment were calculated. Results: Sixty-four nondialysis CRF patients with laboratory investigations of the preceding 6 months were included; 12 patients discontinued the treatment. Fifty-two patients with stage IV or V at baseline completed the study. Mean concentrations of estimated glomerular filtration rate (eGFR), serum creatinine, and hemoglobin differed significantly between TPs (eGFR: F = 15.3, p < 0.001; serum creatinine: F = 29.3, p < 0.001; blood urea: F = 2.0, p = 0.159; hemoglobin: F = 53.9, p < 0.001). Pairwise comparisons of the mean differences between TPs are significant for eGFR, creatinine, and hemoglobin. For blood urea, a significant decrease was observed for the treatment period [15.9(↓) mg/dL, standard error 4.0; n = 52], but a nonsignificant increase was observed for the pretreatment period [16.2(↑) mg/dL, standard error 9.8] due to insufficient data for TP -6 (n = 26). The effect sizes for eGFR, creatinine, blood urea, and hemoglobin were medium (0.45, 0.53, 0.44, and 0.30). Conclusions: After 6 months of treatment, statistically and clinically significant improvements of eGFR, creatinine, blood urea, and hemoglobin and a significant shift to better CRF stages were observed. Several cardinal symptoms were also significantly reduced. Randomized controlled trials are warranted to evaluate the effects in comparison to usual care.

RESUMO

CONTEXT: Advanced prostate cancer (PCa) is treated with androgen deprivation therapy (ADT) which results in loss of bone mineral density (BMD) and osteoporosis. OBJECTIVE: To perform a systematic review and meta-analysis of evidence to determine the most effective methods of preventing BMD loss in patients with PCa treated with ADT. EVIDENCE ACQUISITION: A systematic search of the Medline, Embase, and EBM Reviews databases was conducted on July 20, 2016 to identify studies on men who received an intervention to prevent osteoporosis after diagnosis of PCa and treatment with ADT. The Preferred Reporting Items for Systematic Reviews and Meta-analyses statement was followed and the studies found were critically appraised. EVIDENCE SYNTHESIS: Twenty-five studies were included in the review and 13 had quantitative data sufficient for meta-analysis of BMD loss. Bisphosphonates led to a significant improvement in areas assessed: the mean difference was 7.09% (95% confidence interval [CI] 5.05-9.13%; p<0.00001) for lumbar BMD, 4.63% (95% CI 0.87-8.4; p=0.02) for femoral neck BMD, and 3.16% (95% CI 0.09-6.23%; p=0.04) for total hip BMD. Selective estrogen receptor modulators (SERMs) were less effective, exercise studies had inconsistent effects, and denosumab could not be quantitatively analyzed. CONCLUSIONS: Bisphosphonates and denosumab are effective treatments in preventing BMD loss in men with PCa taking ADT. SERMs are a less effective alternative. Exercise programs are insufficient in isolation but have a role as an adjunct for holistic care. PATIENT SUMMARY: In this review we determined the best option for preventing osteoporosis in men with prostate cancer being treated with androgen deprivation therapy. We found that bisphosphonates, denosumab, and selective estrogen receptor modulators (SERMs) were effective, but exercise was not useful in isolation. We conclude that bisphosphonates, denosumab, or SERMs should be used and exercise encouraged.

RESUMO

Polysaccharides extracted from seeds and husk of psyllium were characterized for different physicochemical characteristics, and bioactivities. Extracted polysaccharides are comprised of d-xylose, l-arabinose, d-glucose, d-galactose, and l-rhamnose. Crude husk-polysaccharide was crystalline, whereas rest was amorphous in nature. Husk-polysaccharide was structurally stable, and purified fractions were thermostable. Crude polysaccharides were irregular in shape with non-porous smooth-surface, however purified husk-polysaccharides showed some porosity, and fibrous nature. Husk-polysaccharide showed higher viscosity compared to seed-polysaccharide, but viscosity decreased with the purification. Crude polysaccharides contained hydrogel-like behavior compared to corresponding purified fractions. The purified fractions of seed-polysaccharide showed the utmost antioxidant and scavenging activities with a half-maximal effective concentration of 347.40 ±â€¯1.79 and 362.72 ±â€¯2.75 µg, respectively. Crude seed-polysaccharide showed about 34% anti-proliferation on Huh-7, whereas its purified fractions showed 42% anti-proliferation on HeLa cell line. The study confirms that psyllium polysaccharides are potential natural antioxidant and anti-carcinogenic agent; however a detailed study is needed to explore psyllium for nutraceutical applications.

RESUMO

Exposure to electromagnetic radiation can have a profound impact on human health. Ultraviolet (UV) radiation from the sun causes skin cancer. Blue light affects the body's circadian melatonin rhythm. At the same time, electromagnetic radiation in controlled quantities has beneficial use. UV light treats various inflammatory skin conditions, and blue light phototherapy is the standard of care for neonatal jaundice. Although quantitative measurements of exposure in these contexts are important, current systems have limited applicability outside of laboratories because of an unfavorable set of factors in bulk, weight, cost, and accuracy. We present optical metrology approaches, optoelectronic designs, and wireless modes of operation that serve as the basis for miniature, low-cost, and battery-free devices for precise dosimetry at multiple wavelengths. These platforms use a system on a chip with near-field communication functionality, a radio frequency antenna, photodiodes, supercapacitors, and a transistor to exploit a continuous accumulation mechanism for measurement. Experimental and computational studies of the individual components, the collective systems, and the performance parameters highlight the operating principles and design considerations. Evaluations on human participants monitored solar UV exposure during outdoor activities, captured instantaneous and cumulative exposure during blue light phototherapy in neonatal intensive care units, and tracked light illumination for seasonal affective disorder phototherapy. Versatile applications of this dosimetry platform provide means for consumers and medical providers to modulate light exposure across the electromagnetic spectrum in a way that can both reduce risks in the context of excessive exposure and optimize benefits in the context of phototherapy.

RESUMO

Pump thrombosis remains a serious complication of implantable ventricular assist device therapy and is associated with increased risk of morbidity and mortality. Optimal management strategies remain controversial and are guided largely by limited literature and expert opinion. Medical management of pump thrombosis, including the use of direct thrombin inhibitors, has been associated with mixed results. The purpose of this study is to report the outcomes associated with bivalirudin therapy in LVAD patients with suspected pump thrombosis. A single-center, retrospective observational study of 15 patients with suspected pump thrombosis that were all treated with bivalirudin therapy was conducted. The majority of subjects' initial treatment courses were unsuccessful [9/15 (60%)]; however, 6/15 (40%) achieved an initial improvement in serum lactate dehydrogenase (LDH) levels and were stabilized to be successfully discharged from the hospital. Of the subjects discharged, there was a high rate of recurrence of pump thrombosis within 6 months [5/6 (83.3%)]. Bivalirudin therapy was not associated with a consistent reduction in LDH among all subjects studied, and clinical responses to therapy appear to be associated with high rates of thrombosis recurrence. This study analyzes the largest cohort to date of LVAD patients with pump thrombosis treated with bivalirudin therapy, and suggests that alternative therapies should be considered in management.

RESUMO

BACKGROUND: Using the Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition (Academy/ASPEN) Consensus malnutrition definition, we estimated malnutrition prevalence in a sample of individuals with head and neck cancer (HNC) and compared it with the Patient-Generated Subjective Global Assessment (PG-SGA). We also investigated the utility of the 50-kHz phase angle (PA) and 200-kHz/5-kHz impedance ratio (IR) to identify malnutrition. MATERIALS AND METHODS: Nineteen individuals (18 males, 1 female) scheduled to undergo chemoradiotherapy were seen at 5 time points during and up to 3 months after treatment completion. Multiple-frequency bioelectrical impedance analysis, PG-SGA, nutrition-focused physical examination, anthropometry, dietary intake, and handgrip strength data were collected. RESULTS: Using the Consensus, 67% were found to be malnourished before treatment initiation; these criteria diagnosed malnutrition with overall good sensitivity (94%) and moderate specificity (43%) compared with PG-SGA. Over all pooled observations, "malnourished" (by Consensus but not PG-SGA category) had a lower mean PA (5.2 vs 5.9; P = .03) and higher IR (0.82 vs 0.79; P = .03) than "well-nourished" categorizations, although the clinical relevance of these findings is unclear. PA and IR were correlated with higher PG-SGA score (r = -0.35, r = 0.36; P < .01) and handgrip strength (r = 0.48, r = -0.47; P < .01). CONCLUSION: The Academy/ASPEN Consensus and the PG-SGA were in good agreement. It is unclear whether PA and IR can be used as surrogate markers of nutrition status or muscle loss.

RESUMO

Severe knee flexion contracture greater than 80° is rare and challenging to manage. It is a common complication which occurs after a prolonged course of the rheumatoid arthritis. The case was a 45 year old female patient of Ama vata (rheumatoid arthritis) with sandhijadya and sankoca (contracture deformity) who was hospitalized for 2 months. She was unable to walk since 1 year due to contracture of both knee joints. The patient came on a wheel chair and was unable to walk even with support. She was advised for contracture repair surgery which she refused. After hospitalization she was treated with Nadi svedana twice a day for 20 min each. Simultaneously, passive stretching for 45 s in every 5 min interval was done. She was treated for 2 months. The patient was instructed to continue other Ayurvedic remedies given as the Ama vata (rheumatoid arthritis) treatment. After Nadi svedana, goniometric assessment of the knees contracture was performed every week. She got satisfactory result in stiffness and pain and has been able to walk with support. Extension of both knee joints has improved up to 20° with increased range of motion. Her height has also been increased up to 1.5 cm due to improvement in the extension of the knee joints with better feeling in daily activities during 3 months of follow-up period.

RESUMO

BACKGROUND: Transurethral prostatectomy (TURP) is a common surgical intervention for chronic lower urinary tract symptoms (LUTS). Little large-scale evidence exists on factors related to receipt of non-cancer-related TURP. METHODS: A prospective study of men aged ≥45 years participating in the 45 and Up Study, a large Australian cohort study, without prior prostatectomy and/or bowel/genital/urinary-tract cancer; questionnaire data were linked to hospitalisations and deaths. HRs for TURP were estimated in relation to multiple factors, adjusting for confounders. RESULTS: There were 3416 incident TURPs among 106 769 men (median follow-up 5.8 years), with rates of 1.8, 5.3, 9.1 and 11.4/1000 person-years for ages 45-54, 55-64, 65-74 and ≥75 years, respectively. Age-adjusted rates of TURP varied markedly according to baseline LUTS from 2.2/1000 person-years with no/mild symptoms to 30.7/1000 person-years with severe symptoms. Annual household income ≥$70 000 versus <$20 000, having private health insurance and living in major cities were associated with higher TURP rates; there were no significant differences according to baseline diabetes, stroke, high blood pressure or cardiovascular disease. Men reporting severe versus no physical functioning limitation, high versus low psychological distress or poor versus excellent self-rated health were 36-51% more likely to undergo procedures overall, but were 24-37% less likely to undergo procedures following additional adjustment for need (baseline LUTS). CONCLUSIONS: TURP rates were most strongly related to baseline LUTS and age, consistent with appropriate health services targeting. Lower TURP rates in men experiencing socioeconomic disadvantage and with poor health/disability, after accounting for baseline LUTS, suggest inequity and factors such as frailty and risks related to surgery.

RESUMO

Non-targeted metabolomics implies that psyllium (Plantago ovata) is a rich source of natural antioxidants, PUFAs (ω-3 and ω-6 fatty acids) and essential and sulfur-rich amino acids, as recommended by the FAO for human health. Psyllium contains phenolics and flavonoids that possess reducing capacity and reactive oxygen species (ROS) scavenging activities. In leaves, seeds, and husks, about 76, 78, 58% polyunsaturated, 21, 15, 20% saturated, and 3, 7, 22% monounsaturated fatty acids were found, respectively. A range of FAs (C12 to C24) was detected in psyllium and among different plant parts, a high content of the nutritive indicators ω-3 alpha-linolenic acid CPS (57%) and ω-6 linoleic acid CPS (18%) was detected in leaves. Similarly, total content of phenolics and the essential amino acid valine were also detected utmost in leaves followed by sulfur-rich amino acids and flavonoids. In total, 36 different metabolites were identified in psyllium, out of which 26 (13 each) metabolites were detected in leaves and seeds, whereas the remaining 10 were found in the husk. Most of the metabolites are natural antioxidants, phenolics, flavonoids, or alkaloids and can be used as nutrient supplements. Moreover, these metabolites have been reported to have several pharmaceutical applications, including anti-cancer activity. Natural plant ROS scavengers, saponins, were also detected. Based on metabolomic data, the probable presence of a flavonoid biosynthesis pathway was inferred, which provides useful insight for metabolic engineering in the future. Non-targeted metabolomics, antioxidants and scavenging activities reveal the nutraceutical potential of the plant and also suggest that psyllium leaves can be used as a green salad as a dietary supplement to daily food.

RESUMO

AIM: This study aimed to identify consumer perspectives on topics and outcomes to integrate in the Kidney Health Australia Caring for Australasians with Renal Impairment (KHA-CARI) clinical practice guidelines on autosomal-dominant polycystic kidney disease (ADPKD). METHODS: A workshop involving three concurrent focus groups with 18 consumers (patients with ADPKD (n = 15), caregivers (n = 3)) was convened. Guideline topics, interventions and outcomes were identified, and integrated into guideline development. Thematic analysis was used to analyse the reasons for their choices. RESULTS: Twenty-two priority topics were identified, with most focussed on non-pharmacological management (diet, fluid intake, physical activity, complementary medicine), pain management and psychosocial care (mental health, counselling, cognitive and behavioural training, education, support groups). They also identified 26 outcomes including quality of life (QoL), progression of kidney disease, kidney function, cyst growth and nephrotoxity. Almost all topics and outcomes suggested were identified by health professionals with the exception of five topics/outcomes. Six themes reflected reasons for their choices: clarifying ambiguities, resolving debilitating pain, concern for family, preparedness for the future, taking control and significance of impact. CONCLUSION: Although there was considerable concordance between the priority topics and outcomes of health professionals and consumers for guidelines of ADPKD, there was also important discordance with consumers focused on fewer issues, but particularly on lifestyle, psychosocial support, pain, and QoL and renal outcomes. Active consumer engagement in guidelines development can help to ensure the inclusion of patient-centred recommendations, which may lead to better management of disease progression, symptoms, complications, and psychosocial impact.

RESUMO

Cumin is an annual, aromatic, herbaceous, medicinal, spice plant, most widely used as a food additive and flavoring agent in different cuisines. The study is intended to comprehensively analyse physiological parameters, biochemical composition and metabolites under salinity stress. Seed germination index, rate of seed emergence, rate of seed germination, mean germination time, plant biomass, total chlorophyll and carotenoid contents decreased concomitantly with salinity. In contrast, total antioxidant activity, H2O2, proline and MDA contents increased concurrently with stress treatments. Total phenolic and flavonoid contents were decreased initially about 1.4-fold at 50 mM, and thereafter increased about 1.2-fold at 100 mM NaCl stress. Relative water content remained unchanged up to 50 mM NaCl stress, and thereafter decreased significantly. About 2.8-fold electrolyte leakage was found in 50 mM, which increases further 4-fold at 100 mM NaCl stress. Saturated fatty acids (FAs) increased gradually with salinity, whereas unsaturation index and degree of unsaturation change arbitrarily along with the percent quantity of unsaturated FAs. Total lipid and fatty acid composition were significantly influenced by salinity stress. A total of 45 differentially expressed metabolites were identified, including luteolin, salvianolic acid, kaempferol and quercetin, which are phenolic, flavonoid or alkaloids in nature and contain antioxidant activities. Additionally, metabolites with bioactivity such as anticancerous (docetaxel) and antimicrobial (megalomicin) properties were also identified. The study evidenced that plant shoots are a rich source of metabolites, essential amino acids, phenolic compounds and fatty acids, which unveil the medicinal potential of this plant, and also provide useful insight about metabolic responses under salinity stress.

RESUMO

Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings.
