Long-term efficacy of a rural community-based integrated intervention for prevention and management of chronic obstructive pulmonary disease: a cluster randomized controlled trial in China's rural areas

This study aimed to assess the efficacy of a rural community-based integrated intervention for early prevention and management of chronic obstructive pulmonary disease (COPD) in China. This 18-year cluster-randomized controlled trial encompassing 15 villages included 1008 patients (454 men and 40 women in the intervention group [mean age, 54 ± 10 years]; 482 men and 32 women in the control group [mean age, 53 ± 10 years]) with confirmed COPD or at risk for COPD. Villages were randomly assigned to the intervention or the control group, and study participants residing within the villages received treatment accordingly. Intervention group patients took part in a program that included systematic health education, smoking cessation counseling, and education on management of COPD. Control group patients received usual care. The groups were compared after 18 years regarding the incidence of COPD, decline in lung function, and mortality of COPD. COPD incidence was lower in the intervention group than in the control group (10% vs 16%, <0.05). A decline in lung function was also significantly delayed in the intervention group compared to the control group of COPD and high-risk patients. The intervention group showed significant improvement in smoking cessation compared with the control group, and smokers in the intervention group had lower smoking indices than in the control group (350 vs 450, <0.05). The intervention group also had a significantly lower cumulative COPD-related death rate than the control group (37% vs 47%, <0.05). A rural community-based integrated intervention is effective in reducing the incidence of COPD among those at risk, delaying a decline in lung function in COPD patients and those at risk, and reducing mortality of COPD.

Random-start controlled ovarian stimulation for emergency fertility preservation in a patient with myelodysplastic syndrome: a case report

This study reports a case of a gonadotropin-releasing hormone agonist trigger in a young female with myelodysplastic syndrome (MDS) who underwent fertility preservation using random-start controlled ovarian stimulation. This method involves the stimulation of the ovary regardless of a patient's menstrual-cycle phase. A review of the related literature is also provided. A 17-year-old patient was diagnosed with MDS and required initiation of peripheral blood stem cell transplantation within a maximum of 3 weeks and was in the luteal phase of the menstrual cycle when the possibility of attempting preservation of fertility was presented to her. She opted for a random-start controlled ovarian stimulation with gonadotropins. With successful hemorrhagic prophylaxis, 17 oocytes were retrieved including 10 mature and 7 immature oocytes. Of the immature oocytes, 3 were successfully matured in vitro and a vitrification protocol was used to freeze the 13 mature oocytes.

Quality of Canned mandarin as affected by preservation liquid

This study is integrated within a research line dedicated to evaluate different options to introduce mandarin in Spanish agro-food industries and in both national and international markets. The effects of different preservation liquids (sucrose solution, sucrose and ascorbic acid solution, grape, and grapefruit juices), soluble solids (10, 12, 14 ºBrix), and thermal processing (30 seconds at 98 ºC) on vitamin C, color, carotenoids and sensory quality of canned Satsuma mandarin segments were studied. The liquid preservation that presented the best results was grapefruit juice, which provided the highest vitamin C (323 mg.L-1) and total carotenoids (16.4 mg.L-1) contents (the main carotenoid found was β-cryptoxanthin), intense orange color, high thermal stability, and very good sensory quality (e.g. intense floral and fresh-mandarin aromas and low levels of off-flavors).

Influence of agro-ecological production areas on antioxidant activity, reducing sugar content, and selected phytonutrients of orange-fleshed sweet potato cultivars

Sweet potato is an important staple, and it is mainly known for its contribution of β-carotene in human diet. The effects of cultivar and habitat on this pigment and other nutritional characteristics of the crop still require investigation. In this study, three locally bred cultivars of sweet potato, two of which are orange-fleshed, were grown in three different agro-ecological areas to determine soluble sugar content, β-carotene, and total antioxidants of roots. In addition antioxidant activity, total carotenoids, and chlorophyll content were determined in edible leaves. Reducing sugars, β-carotene, total antioxidants capacity, total carotenoids, and chlorophyll content were significantly affected by environmental conditions. The location at lower altitude and closer to the coastline showed high evapotranspiration, thus reducing sugar content, antioxidant activity, and phytonutrients in both storage roots and leaves. Absence of water stress in agro-ecological locations further inland and at higher altitudes was associated with an increase in these compounds. Free radical scavenging activity of DPPH was higher in the storage roots (610.49 µmoles TE/100g) than in the leaves (426.06 µmoles TE/100g); nevertheless, opposite results were found for the ferric ion reducing activity (FRAP). The deep orange-fleshed cultivar A45 contained high β-carotene (15 mg/100g), which is enough to meet RDA for vitamin A. There is evidence of agro-ecological effect on sweet potato nutritional value.

Glomerulonefrite aguda após infecção de vias aéreas superiores ou pele: análise descritiva de 82 pacientes entre 14 e 64 anos de idade

INTRODUÇÃO: A glomerulonefrite aguda (GNA) após infecção de vias aéreas superiores ou pele é uma doença renal causada geralmente por cepas estreptocócicas nefritogênicas, podendo cursar com quadro súbito de hematúria macroscópica, hipertensão arterial, edema e, ocasionalmente, insuficiência renal aguda, sendo comum na infância e pouco incidente em adultos e indivíduos mais jovens. OBJETIVO: Analisar, de forma descritiva, os dados da apresentação inicial da GNA após infecção de vias aéreas superiores ou pele em pacientes com mais de 14 anos de idade, com ênfase em seus aspectos epidemiológicos e clínicos. PACIENTES E MÉTODOS: Foram analisados os dados clínicos de 82 pacientes, atendidos em nosso Serviço no período de 1972 a 2001, distribuídos em três grupos etários: grupo 1, com indivíduos entre 14 e 20 anos (n = 52); grupo 2, entre 21 e 30 anos (n = 19); e grupo 3, com idade > 31 anos (n = 11). RESULTADOS: Houve um predomínio do quadro entre pacientes mais jovens (grupo 1), do sexo masculino e da cor branca, precedido, principalmente, por infecção de pele, manifestando-se mais comumente por edema de membros inferiores e/ou face. Em alguns casos, até com síndrome nefrótica, e hipertensão arterial, sobretudo nos adultos com mais de 30 anos (grupo 3), sendo menos frequente o achado de hematúria macroscópica e, raramente, de insuficiência renal aguda. CONCLUSÃO: Nossos achados ressaltam a importância de se estudar a GNA após infecção de vias aéreas superiores ou pele em indivíduos mais jovens e adultos, procurando melhor caracterizar seus aspectos clínicos, sobretudo por se tratar de um grupo de pacientes no qual a doença é menos incidente.

Storage of Tabebuia caraiba (Mart.) Bureau seeds in different packaging and temperatures

Tabebuia caraiba (Mart.) Bureau, commonly known as Silver Trumpet Tree is a forestal species, belonging to Bignoniaceae family, which can be utilized as medicinal plant or in landscaping of urban and rural areas; besides producing large mechanical resistance wood. Despite its wide use and ecological importance, basic studies on storages of their seeds are scarce. This way, the objective of this study was to determine the most adequate packaging and the best temperatures, for storing seeds of T. caraiba. For this, seeds were stored in two types of packaging: Kraft paper bags and transparent polyethylene bags; which were then stored during 150 days under three different environments: laboratory normal environment (25±2 °C); cold chamber (8±2 °C); and refrigerator (6±2 °C). After periods of 0, 30, 60, 90, 120, and 150 days, seed moisture content, percentage of emergence, emergence speed index, and seedling length were evaluated. Seeds of T. caraiba kept in packaging of paper and polyethylene bags and stored at laboratory environmental condition, have lost more quickly their vigor along the storage period. For storage, it is recommended the maintenance of T. caraiba seeds in polyethylene bags into cold chamber; and/or polyethylene bags or Kraft paper bags into refrigerator.

The geographic dynamics of industry employment in Brazilian metropolitan areas: lessons for São Paulo

ABSTRACTWe discuss historic trends in large metropolitan areas in Brazil showing that manufacturing has decreased its share in the country but the movement was, in general, more intense in large metropolitan areas and particularly in the São Paulo Metropolitan Area (SPMA). This movement was more intense in the 1980s and in the first half of the 1990s. From mid 1990s up to the end of the 2000s, the manufacturing share trend became flat. We speculate that the first period reflects the exhaustion of the process of import substitution that took place in the previous three decades (1950 to 1980). The second period, from 1993 to 2009, is representative of a new model of growth and the evidence that manufacturing share became flat is reinforcing the idea of a new period in terms of manufacturing employment. While concentration has risen from 1996 to 2005, it decreased again in the second half of the first decade of the 2000s. The SPMA reinvented itself very quickly from late 1970s to mid-2000s.

Quaternary geology of the Campbellford, Trenton, Consecon, Tweed, Belleville, Wellington, Sydenham, Bath, and Yorkshire Island map-areas, Ontario /

Sediment relationships observed during geological mapping in southeastern Ontario indicate a relatively simple deglaciation history for the area during late Wisconsin time. The ice from the north (part of the Lake Simcoe lobe) and the Lake Ontario ice lobe, which were coalesced during most of late Wisconsin time, initially separated along the crest of the Oak Ridges Moraine. Available data indicate that the Oak Ridges Moraine is composed primarily of sediments pre-late Wisconsin in age capped by late Wisconsin till and interlobate deposits. Retreat of the northern ice was relatively steady and resulted in the deposition of the Dummer Moraines, a facies of the drumlinized till to the south. Retreat of the Lake Ontario ice lobe into the Lake Ontario basin was interrupted by a re-advance which covered the southeastern half of the map area. The northern ice had already retreated from the area by this time. The Lake Ontario lobe was fed through the St. Lawrence Valley, indicating that the Ottawa Valley was ice filled at this time. High level glacial lakes fronted the ice during deglaciation. These waters quickly fell to low levels as the ice retreated from the St. Lawrence Valley, opening lower outlets.

The Conceptualization and Exploration of Place Allegiance: Towards a Unified Model of Person-Place Relationships within Outdoor Recreation

The academic study of place has been generally defined by two distinct and highly refined discourses within outdoor recreation research: place attachment and sense of place. Place attachment generally describes the intensity of the place relationship, whereas sense of place approaches place from a more holistic and intimate orientation. This study bridges these two methodological and theoretical separate areas of place research together by re-conceptualizing the way in which place relationships are viewed within outdoor recreation research. The Psychological Continuum Model is used to extend the language of place attachment to incorporate more of the philosophy of sense of place while attending to the empirical strength and utility of place attachment. This extension results in the term place allegiance being coined to depict the strong and profound relationships outdoor recreationists build with their places of outdoor recreation. Using a concurrent mixed methods research design, this study explored place allegiance via an online survey (n = 437) and thirteen in-depth qualitative interviews with outdoor recreationists. Results indicate that place allegiance can be measured through a multi-dimensional model of place allegiance that incorporates behaviours, importance, resistance, knowledge and symbolic value. In addition, place allegiance was found to be related to an individual's influence on life course and his/her willingness to exhibit preservation and protection tendencies. Place allegiance plays an important role in acknowledging the importance of authentic place relationships in an effort to confront placelessness. Wilderness recreation is an important avenue for outdoor recreationists to build strong place relationships.
