Electronic clinical records in primary care for estimating disease burden and management. An example of COPD

Chronic obstructive pulmonary disease (COPD) is a significant health problem in developed countries. We aimed to estimate the prevalence of COPD in a single Spanish healthcare area. We also aimed to assess if there are any differences in prevalence and spirometry use among primary care services by utilizing already registered information. We designed a cross-sectional study to determine the prevalence of COPD and the performance of spirometries in each primary care service. A total of 8,444 patients were diagnosed with COPD, with a prevalence of 2.6% for individuals older than 39 years. The prevalence increased with age and was much higher in men. Significant heterogeneity was found in the prevalence of COPD and spirometry use among primary care services. COPD was underdiagnosed and there was wide variability in spirometry use in our area. Greater efforts are needed to diagnose COPD in order to improve its clinical outcomes and to refine registries so that they can be used as reliable sources of information

Optimizing access and configuration of trauma centre care in New South Wales

IntroductionGetting the right patient, to the right place, at the right time is dependent on a multitude of modifiable and non-modifiable factors. One potentially modifiable factor is the number and location of trauma centres (TC). Overabundance of TC dilutes volumes and could be associated with worse outcomes. We describe a methodology that evaluates trauma system reconfiguration without reductions in potential access to care. We used the mature trauma system of New South Wales (NSW) as a model given the perceived overabundance of urban major trauma centres (MTC).MethodsWe first evaluated potential access to TC care via ground and air transport through the use of geographic information systems (GIS) network analysis. Potential access was defined as the proportion of the population living within 60-min transport time from a potential scene of injury to a TC by ground or rotary-wing aircraft. Sensitivity analyses were carried out in order to account for potential pre-hospital interventions and/or transport delays; travel times of 15-, 30-, 45-, 60-, and 90-min were also analyzed. We then evaluated if the current configuration of the system (number of urban MTS in the Sydney basin) could be optimized without reductions in potential access to care using two GIS methodologies: location-allocation and individual removal of MTC.Results86% of the NSW population has potential access to a TC within 60 min ground travel time; potential access improves to 99% with rotary-wing transport. The 1% of the population without potential TC access lives in 48% of the land area (>384,000km2). Utilizing two different methodologies we identified that there was no change in potential access by ground transport after removing 1 or 2 MTC in the Sydney basin at the 30-, 45-, and 60-min transport times. However, 0.02% and 0.5% of the population would not have potential access to MTC care at 15 min after removing one and two MTC respectively.DiscussionRedistribution of the number of MTC in the Sydney basin could be achieved without a significant impact on potential access to care. Our approach can be utilized as an initial tool to evaluate a trauma system where overabundance of coverage is present.     

Normative values of the motor competence assessment (MCA) from 3 to 23 years of age

ObjectivesGrowing evidence of the importance of motor competence for developing a healthy lifestyle has been established in the last decade. Nonetheless, no single instrument or observation tool have been able to fully measure this construct, particularly because most were built for the diagnosis of children in risk for motor impairment; are limited to a few years of the developmental span; lack objectivity in the assessment protocols; or do not include the locomotor, stability, and manipulative components. This led to the difficulty of comparing researches, and longitudinally follow children into adulthood. Recently, a novel proposal to assess motor competence was presented - the Motor Competence Assessment (MCA) - and this study aims to present the MCA normative data from 3-to-23 years.Design and methodsTwo thousand and eighty-seven participants (1102 boys) between 3 and 23 years of age were evaluated in the MCA (standing long jump, 10 m shuttle run, throwing velocity, kicking velocity, lateral jumps, shifting platforms). Results for each test were introduced in the LMS Chartmaker 2.3. The best model for test and sex was used, resulting in normative curves and percentile values.ResultsFinal norms showed a good fit to the instrument developmental expectations, allowing to differentiate and classify performances along the age interval.ConclusionsThe MCA age- and sex- normative values allow to assess motor competence from childhood to early adulthood. Future directions will include obtaining a total MCA score and the normative scores for the MCA components (stability, locomotion, object control), and to expand the norms to adulthood and old age.     

三种固定剂对氯化金染色大鼠运动终板效果的比较

目的 对比分析25%甲酸、25%乙酸和4%甲醛3种固定剂对氯化金染色运动终板的效果。方法 选用30只SD大鼠,体重180～220 g,雌雄不拘。进行10次实验,每次实验随机选取3只,取右侧肱二头肌,分别置于25%甲酸、25%乙酸和4%甲醛溶液中固定后,行氯化金镀金法,光学显微镜下观察运动终板的形态结构和背景颜色。结果 3种固定剂固定的运动终板边缘整齐,中央颜色浅于周围,部分运动终板中央呈空泡状。甲酸固定的肌纤维排列有序,横纹清晰,呈紫红色;乙酸固定的肌纤维排列有序,无清晰的横纹,呈紫蓝色,但染色较浅,与运动终板形成的反差较小;甲醛固定的肌纤维排列杂乱,无横纹,呈紫红色、粉红色、紫黑色和蓝色等多种颜色。结论 甲酸固定的运动终板氯化金染色效果优于乙酸和甲醛,甲酸固定的肌组织需要的还原时间少于乙酸和甲醛。因此,进行运动终板染色选择固定剂时,25%甲酸在3种固定试剂中可作为最佳选择。     

COVID‐19 and maternal and child food and nutrition insecurity: a complex syndemic

Globally, the COVID‐19 pandemic has already led to major increases in unemployment and is expected to lead to unprecedented increases in poverty and food and nutrition insecurity, as well as poor health outcomes. Families where young children, youth, pregnant and lactating women live need to be protected against the ongoing protracted pandemic and the aftershocks that are very likely to follow for years to come. The future wellbeing of the vast majority of the world now depends on reconfiguring the current ineffective food, nutrition, health, and social protection systems to ensure food and nutrition security for all. Because food, nutrition, health, and socio‐economic outcomes are intimately inter‐linked, it is essential that we find out how to effectively address the need to reconfigure and to provide better intersecoral coordination among global and local food, health care, and social protection systems taking equity and sutainability principles into account. Implementation science research informed by complex adaptive sytems frameworks will be needed to fill in the major knowledge gaps. Not doing so will not only put the development of individuals at further risk, but also negatively impact on the development potential of entire nations and ultimately our planet.     

Prevalence of and factors contributing to anxiety,depression and cognitive disorders among urban elderly in Odisha – A study through the health systems’ Lens

IntroductionGrowing geriatric mental health needs of urban population in India pose several programmatic challenges. This study aimed to assess anxiety, depression and cognitive disorders among urban elderly, and explore availability of social support mechanisms and of a responsive health system to implement the national mental health programme.Methods244 respondents were randomly selected from Berhampur city. We administered a semi-structured interview schedule to assess substance abuse, chronic morbidity, anxiety, depression and cognitive abilities. Further, in-depth interviews were conducted with 25 key informants including district officials, psychiatrists, and programme managers. We used R software and ‘thematic framework’ approach, respectively, for quantitative and qualitative data analysis. Ethical standards were complied with.ResultsAbout half of the respondents were economically dependent; 57.3% had moderate to severe anxiety; 46.7% had moderate to severe depression; while about 25% had severe cognitive impairments. We found association of chewing tobacco (1.34(0.28–2.40)) and depression (0.52(0.37–0.68)) with anxiety; negative perception about elderly-friendly society (1.64(0.75–2.53)) and physical inactivity (2.88(1.60–4.16)) with depression; and age (-0.11(-0.20 – -0.02)) and physical inactivity (-3.44(-5.13 – -1.74)) with cognitive disorders. Qualitative analysis revealed lack of awareness, social stigma, poor availability of trained human resources, and poor political commitment as important systemic barriers to early detection and treatment of mental ailments among the elderly.ConclusionEstablishing tobacco cessation centres, sensitizing community about mental health needs of elderly, incentivizing physical activity of elderly, integrating mental health with primary care, multi-skilling providers and developing a cadre of community counsellors need urgent attention of policy makers and programme implementers.     

"催眠态"与"气功态"脑运动皮质低频活动差异的初步研究

目的:研究催眠态和气功态下脑运动皮质的低频同步活动,探讨催眠态与气功态对脑功能皮质活动的不同效应。材料和方法:研究对象为1例28岁的健康女性志愿者,右利手。采用气功入静和催眠诱导分别进入气功态和催眠态。研究采用GEsigna VH/i3.0T磁共振扫描机,先后进行无任务(静息态、催眠态和气功态)和运动任务的BOLD序列扫描。图像的处理先以运动任务获得的运动皮质定位作为种子对三种状态的功能图像做交互相关分析,获得脑功能连接的激活图,然后对这些激活的体素采用功率谱分析,获得相应的优势频率和能量。结果:脑功能低频连接激活体素的数量在静息态、催眠态、气功态间没有明显差异,但通过功率谱分析,催眠态主要表现为优势频率能量的升高,而气功态则主要表现为优势频率的增加。结论:气功态和催眠态下脑运动皮质的低频活动存在一定的差异,提示两种状态有通过不同的途径产生效应,但其生理基础有待于进一步研究。
