Effectiveness and Equity in Community-Based Rehabilitation on Pain, Physical Function, and Quality of Life After Unilateral Lower Limb Amputation: A Systematic Review.

OBJECTIVES: To synthesize evidence for (1) the effectiveness of exercise-based rehabilitation interventions in the community and/or at home after transfemoral and transtibial amputation on pain, physical function, and quality of life and (2) the extent of inequities (unfair, avoidable differences in health) in access to identified interventions. DATA SOURCES: Embase, MEDLINE, PEDro, Cinahl, Global Health, PsycINFO, OpenGrey, and ClinicalTrials.gov were systematically searched from inception to August 12, 2021, for published, unpublished, and registered ongoing randomized controlled trials. STUDY SELECTION: Three review authors completed screening and quality appraisal in Covidence using the Cochrane Risk of Bias Tool. Included were randomized controlled trials of exercise-based rehabilitation interventions based in the community or at home for adults with transfemoral or transtibial amputation that assessed effectiveness on pain, physical function, or quality of life. DATA EXTRACTION: Effectiveness data were extracted to templates defined a priori and the PROGRESS-Plus framework was used for equity factors. DATA SYNTHESIS: Eight completed trials of low to moderate quality, 2 trial protocols, and 3 registered ongoing trials (351 participants across trials) were identified. Interventions included cognitive behavioral therapy, education, and video games, combined with exercise. There was heterogeneity in the mode of exercise as well as outcome measures employed. Intervention effects on pain, physical function, and quality of life were inconsistent. Intervention intensity, time of delivery, and degree of supervision influenced reported effectiveness. Overall, 423 potential participants were inequitably excluded from identified trials (65%), limiting the generalizability of interventions to the underlying population. CONCLUSIONS: Interventions that were tailored, supervised, of higher intensity, and not in the immediate postacute phase showed greater promise for improving specific physical function outcomes. Future trials should explore these effects further and employ more inclusive eligibility to optimize any future implementation

Silicon Supplementation by Rice Hull Leachate on the Growth, Yield, Fruit Parameters and Anthracnose Disease Resistance of Capsicum ‘MuriaF1’

Silicon has prooven beneficial in growth, yield and disease resistance of plants. Currently, the differentchemical sources; sodium silicate, potassium silicate and calcium silicate have been used to supply Si forplants. However, rice hull is one of the natural sources of Si which has not properly utilized. It has beenreported that 5 g of rice hull leach 40 ppm of soluble Si in a week of soaking period. Thus, this research wasconducted to investigate the effect of rice hull leachate as a Si source, on growth, yield and fruit parametersand also disease resistance of hydroponically grown Capsicum annum L. ‘Muria F1’. Leaching studies wereconducted to determine the optimum level of Si leached by rice hull, by soaking them in different time periods(days). This leachate was incorporated to the plants grown in hydroponic media supplemented with twodifferent nutrient solutions i.e Nutrient formula (NF) and Albert solution.The growth, yield and fruit qualityparameters were measured and the resistance against anthracnose disease was assessed by artificialinoculation of fruits with Colletotrichum gloeosporioides and measuring the lesion area. Capsicum plantsgrown in rice hull leachate with either nutrient solution showed significant increase in, shoot length (>12%),number of leaves (>27%), leaf area (>42%) fruit length (>12%), fruit fresh weight (>37%) and yield(>44%) and also a significant reduction of anthracnose disease (>43%) compared to control. The resultsrevealed that rice hull leachate could be used as a low cost silicon source in hydroponic media to enhanceperformance of Capsicum cv. Muria F1.Keywords: Rice hull, Capsicum annum L., silicon, Colletotrichum gloeosporioides, hydroponic

Dietary fibers, starch fractions and nutritional composition of finger millet varieties cultivated in Sri Lanka

Soluble, insoluble and total dietary fiber contents, rapidly and slowly digestible starch contents, arabinoxylans, β-glucans, fructans, resistant starch, amylose and total sugar contents, minerals and trace elements compositions and proximate compositions of three finger millet varieties, namely Ravi, Rawana and Oshadha, were evaluated using standard protocols. There were no significant differences (P≥ 0.05) among the rapidly digestible starch, arabinoxylans, β-glucans, fructans, amylose, total sugar, protein, crude fat and crude fiber contents of Ravi, Rawana and Oshadha varieties. Total dietary fiber contents varied between 13.01% (Ravi) and 13.79% (Oshadha). Slowly digestible starch contents ranged from 43.38% (Ravi) to 49.15% (Oshadha) and resistant starch contents ranged from 3.75% (Ravi) to 4.58% (Oshadha). Ash content of Ravi (3.22%) was significantly higher (P < 0.05) than ash contents of other two varieties. Average sodium, magnesium, potassium, calcium, iron, zinc and phosphorous contents of three finger millet varieties were 12.04, 141.78, 407.15, 345.62, 3.49, 1.89 and 331.07 mg/100 g, respectively. Findings of the present study indicated that studied finger millet varieties were good sources of dietary fibers (including resistant starch) as well as minerals and trace elements (especially potassium, calcium, phosphorous and iron) when compared to commonly consumed cereals such as rice and wheat

Мониторинг воспроизводства и влияния фекального прогестерона на репродуктивную цикличность циклов самбарского оленя Шри-Ланки (Rusa unicolor unicolor)

Sambar deer hinds, estrus, progesterone, estrous cycle, Sri LankaThis study examines the length of the estrous cycle in 16 Sambar deer hinds in National zoological gardens in Dehiwala and Kegalle, Sri Lanka (NZGDK) assessed with the use of changes in progesterone concentrations, along with the changes in the profile of this hormone and by the visual estrus manifestations. The objectives of the present study were to characterize ovarian activity throughout the estrous cycle and the non-pregnant luteal phase of captive sambar deer in Sri Lanka. These objectives were achieved with the use of radioimmunoassay (RIA) to measure fecal concentrations of progesterone and visual estrus manifestation. Fecal samples were collected from non-pregnant sambar deer hinds (aged 2–4 years)over the period of six months on daily basis, both during breeding and non-breeding seasons. Estrous cycles were recorded in non-pregnant females, based on fecal progesterone concentrations. The average estrous cycle length was 26.1±2.08 days (mean ± SEM) and 2.10 ± 0.51 days in the inter-luteal phase.The average fecal progesterone concentrations attained the peak mid-luteal values of 2.74 ng mL–1. There appeared to be variation in fecal progesterone amplitude between animals and between dates, but the low frequency of sampling prohibited confirmation of trends. Behavioral estrus was detected only when the average progesterone concentrations were less than 0.07 ng mL–1. However, not all periods of depressed progesterone secretion were associated with the observed estrus. Behavioral estrus was detected in hinds when progesterone concentrations were less than 0.07 ng mL–1; a subsequent rise in progesterone indicated ovulation taking place at this time

Relationships between plasma lipids species, gender, risk factors and Alzheimer’s disease

Background: Lipid metabolism is altered in Alzheimer’s disease (AD); however, the relationship between AD risk factors (age, APOE ɛ4, and gender) and lipid metabolism is not well defined. Objective: We investigated whether altered lipid metabolism associated with increased age, gender, and APOE status may contribute to the development of AD by examining these risk factors in healthy controls and also clinically diagnosed AD individuals. Methods: We performed plasma lipidomic profiling (582 lipid species) of the Australian Imaging, Biomarkers and Lifestyle flagship study of aging cohort (AIBL) using liquid chromatography-mass spectrometry. Linear regression and interaction analysis were used to explore the relationship between risk factors and plasma lipid species. Results: We observed strong associations between plasma lipid species with gender and increasing age in cognitively normal individuals. However, APOE ɛ4 was relatively weakly associated with plasma lipid species. Interaction analysis identified differential associations of sphingolipids and polyunsaturated fatty acid esterified lipid species with AD based on age and gender, respectively. These data indicate that the risk associated with age, gender, and APOE ɛ4 may, in part, be mediated by changes in lipid metabolism. Conclusion: This study extends our existing knowledge of the relationship between the lipidome and AD and highlights the complexity of the relationships between lipid metabolism and AD at different ages and between men and women. This has important implications for how we assess AD risk and also for potential therapeutic strategies involving modulation of lipid metabolic pathways

Work related complaints of neck, shoulder and arm among computer office workers: a cross-sectional evaluation of prevalence and risk factors in a developing country

<p>Abstract</p> <p>Background</p> <p>Complaints of arms, neck and shoulders (CANS) is common among computer office workers. We evaluated an aetiological model with physical/psychosocial risk-factors.</p> <p>Methods</p> <p>We invited 2,500 computer office workers for the study. Data on prevalence and risk-factors of CANS were collected by validated Maastricht-Upper-extremity-Questionnaire. Workstations were evaluated by Occupational Safety and Health Administration (OSHA) Visual-Display-Terminal workstation-checklist. Participants' knowledge and awareness was evaluated by a set of expert-validated questions. A binary logistic regression analysis investigated relationships/correlations between risk-factors and symptoms.</p> <p>Results</p> <p>Sample size was 2,210. Mean age 30.8 ± 8.1 years, 50.8% were males. The 1-year prevalence of CANS was 56.9%, commonest region of complaint was forearm/hand (42.6%), followed by neck (36.7%) and shoulder/arm (32.0%). In those with CANS, 22.7% had taken treatment from a health care professional, only in 1.1% seeking medical advice an occupation-related injury had been suspected/diagnosed. In addition 9.3% reported CANS-related absenteeism from work, while 15.4% reported CANS causing disruption of normal activities. A majority of evaluated workstations in all participants (88.4%,) and in those with CANS (91.9%) had OSHA non-compliant workstations. In the binary logistic regression analyses female gender, daily computer usage, incorrect body posture, bad work-habits, work overload, poor social support and poor ergonomic knowledge were associated with CANS and its' severity In a multiple logistic regression analysis controlling for age, gender and duration of occupation, incorrect body posture, bad work-habits and daily computer usage were significant independent predictors of CANS</p> <p>Conclusions</p> <p>The prevalence of work-related CANS among computer office workers in Sri Lanka, a developing, South Asian country is high and comparable to prevalence in developed countries. Work-related physical factors, psychosocial factors and lack of awareness were all important associations of CANS and effective preventive strategies need to address all three areas.</p

Profesionalna astma u radnika izloženih prašinama iz biljnih i voćnih čajeva

We performed a cross-sectional study to detect occupational asthma (OA) in 63 subjects occupationally exposed to herbal and fruit tea dust and in 63 corresponding controls. The evaluation included a questionnaire, skin prick tests to workplace and common inhalant allergens, spirometry, and histamine challenge test. The evaluation of the work-relatedness of asthma in the exposed workers was based on serial peak expiratory flow rate (PEFR) measurements and bronchoprovocation tests. We found a higher prevalence of respiratory symptoms in the exposed workers, whereas spirometric parameters were significantly lower. The prevalence of sensitisation to allergens and of bronchial hyperresponsivenss (BHR) did not differ significantly between the groups. The prevalence of asthma was also similar in both groups (8.0 % vs. 6.4 %; P=0.540). Work-relatedness of symptoms was reported by all asthmatic tea workers and by no control with asthma. Significant work-related changes in PEFR diurnal variations and in non-specific BHR, suggesting allergic OA, were found in one tea worker with asthma (1.6 %). No specific workplace agent causing OA in the affected subject was identified. None of the tea workers with asthma met the criteria for medical case definition of the reactive airway dysfunction syndrome (RADS). Our data confirm workplace exposure to herbal and fruit tea dust as a risk factor for OA.Svrha je ovoga presječnog ispitivanja bila otkriti profesionalnu astmu u skupini od 63 ispitanika koji su na radnome mjestu bili izloženi prašinama biljnih i voćnih čajeva. Kao kontrola uzet je jednak broj uredskih radnika koji nisu bili izloženi ovim prašinama. Ocjena izloženih i kontrolnih ispitanika obuhvatila je upitnik, skin prick testove na uobičajene i profesionalne inhalacijske alergene, spirometriju te histaminski test. Povezanost astme s profesionalnom izloženosti u radnika utvrđena je prema kriterijima Američkog kolegija pulmologa (American College of Chest Physicians, krat. ACCP), a na temelju mjerenja niza vršnih ekspiratornih protoka (engl. peak expiratory flow rate, PEFR) i niza bronhoprovokativnih testova. Izloženi su radnici iskazali veću prevalenciju respiratornih simptoma odnosno niže spirometrijske vrijednosti od kontrole. Izloženi ispitanici nisu se značajno razlikovali od kontrole u prevalenciji senzibilizacije na profesionalne i uobičajene inhalacijske alergene te prevalenciji pretjerane bronhalne reaktivnosti (engl. bronchial hyperresponsiveness, krat. BHR). Isto vrijedi i za prevalenciju astme (8,0 % u izloženih radnika prema 6,4 % u kontrola; P=0,540). Povezanost simptoma s poslom prijavili su svi radnici u obradi čaja oboljeli od astme te ni jedan kontrolni ispitanik s astmom. U jednoga astmatičnog radnika na čaju utvrđene su značajne promjene u dnevnim varijacijama PEFR-a te u nespecifičnom BHR-u koji upućuju na profesionalnu astmu (1.6 %). Nije utvrđeno koja je to tvar uzrokovala profesionalnu astmu u ovog ispitanika. Nitko od izloženih radnika s astmom nije zadovoljio sve medicinske kriterije za dijagnozu sindroma reaktivne disfunkcije dišnih putova (engl. reactive airway dysfunction syndrome, RADS). Naši podaci potvrđuju da je profesionalna izloženost prašinama iz biljnih i voćnih čajeva čimbenik rizika od profesionalne astme

Concordant peripheral lipidome signatures in two large clinical studies of Alzheimer’s disease

© 2020, The Author(s). Changes to lipid metabolism are tightly associated with the onset and pathology of Alzheimer’s disease (AD). Lipids are complex molecules comprising many isomeric and isobaric species, necessitating detailed analysis to enable interpretation of biological significance. Our expanded targeted lipidomics platform (569 species across 32 classes) allows for detailed lipid separation and characterisation. In this study we examined peripheral samples of two cohorts (AIBL, n = 1112 and ADNI, n = 800). We are able to identify concordant peripheral signatures associated with prevalent AD arising from lipid pathways including; ether lipids, sphingolipids (notably GM3 gangliosides) and lipid classes previously associated with cardiometabolic disease (phosphatidylethanolamine and triglycerides). We subsequently identified similar lipid signatures in both cohorts with future disease. Lastly, we developed multivariate lipid models that improved classification and prediction. Our results provide a holistic view between the lipidome and AD using a comprehensive approach, providing targets for further mechanistic investigation
