Early identification of patients with acute myocardial infarction is of prime importance due to the associated very high mortality.
Only 22% of the patients presenting at emergency cardiology care with chest pain have coronary disease. A number of biochemical
tests like CKMB and Troponin-T/I have been introduced for early detection of the coronary syndrome (ACS). Ischemia modified
albumin (IMA) has been recently introduced as a marker of myocardial ischemia. We estimated serum IMA in four sequential samples
from 25 patients admitted to ICCU. Twenty five healthy volunteers formed the control group from which the normal range was
derived. IMA was significantly raised in ischemia patients than in controls as well as compared to the patients who did not
have cardiac ischemia. IMA demonstrated good discrimination between the ischemic and the non-ischemic patients with an Odds
Ratio of 16.9 (6.29–46.87) than CKMB which showed an Odds Ratio of 2.07 (1.18–6.08). Sensitivity and specificity of IMA for
the detection of ACS was 78.0% and 82.7% compared to 58.0% and 60.0%, respectively for the CK-MB assay. The area under the
ROC curve of IMA for ischemic v/s non-ischemic patients was 0.834. IMA appears to be developing into a new and very potent
marker, of cardiac ischemia. 相似文献

What impact does the strengthening of child rights have on the experience and circumstances of children? CRC General Comment 13 emphasizes that defining measurable targets for improvements in child protection is a key element of efforts to strengthen child rights and well-being across the world. This paper describes an attempt to identify key domains relevant to such mapping of child protection indicators, and the feasibility of collecting data—from existing data sources or otherwise—to complete a “National Child Protection Index Report” summarizing achievements and concerns at a national level.Methods
A process of inter-agency consultation was facilitated by the CPC Learning Network to establish a template for the Index Report. The template was modeled on that used for the “Countdown to 2015” maternal, neonatal and child health initiative, aiming to capture indices not only of key protection risks but also implementation and coverage of key protection measures. The work drew on indicator development and policy initiatives by a number of international child protection agencies. The template developed was used as a basis to pilot national data collection in Indonesia and, at a sub-national level, in northern Uganda.Findings
The template provides a concise summary of protection issues of relevance to a broad range of constituencies, global and national. However, in the pilot settings, existing routine data collection was inadequate to effectively populate a large proportion of indicators. Mechanisms of collating findings from discrete assessments—another potential source of data for completion of the index report—were also generally underdeveloped.Practice implications
In settings where state infrastructure allows the collection and analysis of routine data in such domains as health and economic activity, such efforts should be extended to the child protection sector. Discrete assessments by governmental or non-governmental agencies also provide significant potential for more effective sharing and collation of information. National Child Protection sub-clusters or equivalent structures can play an important role in facilitating both of these processes. 相似文献3.
Surface features such as uneven playing surfaces, low impact absorption capacity and inappropriate friction/traction characteristics are connected with injury prevalence whereas force impact during foot strike has been suggested to be an important mechanism of intravascular haemolysis during running. We aimed to evaluate intravascular haemolysis during running and compare the effect of running on two different types of surfaces on haemolysis. We selected two surfaces (asphalt and grass) on which these athletes usually run. Participants were randomly assigned to group A (asphalt) or group B (grass) with 10 athletes in each group. Each athlete completed one hour of running at the calculated target heart rate (60-70%). Venous blood samples were collected before and immediately after running. We measured unconjugated bilirubin (UBR) (mg · dl(-1)), lactate dehydrogenase (LDH) (μ · ml(-1)), haemoglobin (g · l(-1)) and serum ferritin (ng · ml(-1)) as indicators of haemolysis. Athletes who ran on grass demonstrated an increase in the haematological parameters (UBR: P < 0.01, LDH: P < 0.05) when compared to athletes who ran on asphalt (UBR: P < 0.05, LDH: P = 0.241). Our findings indicate that intravascular haemolysis occurs significantly after prolonged running. Furthermore, we conclude that uneven grass surface results in greater haemolysis compared to asphalt road. 相似文献

In this information age, the capacity to perceive structure in data, model that structure, and make decisions regarding its
implications is rapidly becoming the most important of the quantitative literacy skills. We build on Kaput’s belief in a Science
of Need to motivate and direct the development of tasks and tools for engaging students in reasoning about data. A Science
of Need embodies the utility value of mathematics, and engages students in seeing the importance of mathematics in both their
current and their future lives. An extended example of the design of tasks that require students to generate, test, and revise
models of complex data is used to illustrate the ways in which attention to the contributions of students can aid in the development
of both useful and theoretically coherent models of mathematical understanding by researchers. Tools such as Fathom are shown
as democratizing agents in making data modeling more expressive and intimate, aiding in the development of deeper and more
applicable mathematical understanding.

Engagement in social and leisure activities is an indicator of quality of life and well-being in nursing homes. There are few studies in which nursing home residents with dementia self-reported their experiences in activity engagement. This qualitative study describes types of current activity involvement and barriers to activities as perceived by nursing home residents with dementia. Thirty-one residents participated in short, open-ended interviews and six in in-depth interviews. Thematic content analysis showed that participants primarily depended on activities organized by their nursing homes. Few participants engaged in self-directed activities such as walking, visiting other residents and family members, and attending church services. Many residents felt they had limited opportunities and motivation for activities. They missed past hobbies greatly but could not continue them due to lack of accommodation and limitation in physical function. Environmental factors, along with a fixed activity schedule, further prevented them from engaging in activities. Residents with dementia should be invited to participate in activity planning and have necessary assistance and accommodation in order to engage in activities that matter to them. Based on the findings, a checklist for individualizing and evaluating activities for persons with dementia is detailed. 相似文献

Study was undertaken to assess thyroid status in hyperemesis gravidarum. 150 women pregnant with <20 weeks of gestation were
selected randomly and out of these 100 women presenting with hyperemesis formed study group while 50 normal pregnant women
served as controls. 53% of hyperemetic pregnant women were primigravidae and 82% of pregnant women presented with vomiting
at less than 12 weeks of gestation. Statistically significant, 22% of hyperemetic women had increased serum T3 levels while T4 levels were increased in 67% of women in study group as compared to 8% and 16% respectively in control group. TSH levels
were decreased in 18% of hyperemetic women as compared to 8% in control group with decrease in mean TSH level statistically
significant. 22% of hyperemetic women had electrolyte disturbances and 7% were ketonuric. In clinically euthyroid women, biochemically
altered thyroid function can attribute to vomiting and its prolongation to second trimester 相似文献

A 44-item survey instrument was designed to determine secondary students?? views about how useful various specific actions related to reducing global warming might be, their willingness to undertake these various actions and the extent to which these 2 might be linked. The instrument was administered to students in grades 6??C?10 (n?=?768) from 4 large schools in metropolitan Delhi, India in which the teaching language was English. The findings indicated that this cohort of Indian students exhibited high levels of concern about climate change and strong willingness to act against global warming and in favour of the environment. The findings are tentatively compared with those from 2 similar survey studies conducted in Western contexts (Spain and Australia). 相似文献

Lung surfactant, a lipo-protein complex, is a highly surface-active material found in the fluid lining the air-liquid interface
of the alveolar surface. Surfactant plays a dual function of preventing alveolar collapse during breathing cycle and protection
of the lungs from injuries and infections caused by foreign bodies and pathogens. Varying degrees of structure-function abnormalities
of surfactant have been associated with obstructive lung diseases, respiratory infections, respiratory distress syndromes,
interstitial lung diseases, pulmonary alveolar proteinosis, cardiopulmonary bypass surgery and smoking. For some pulmonary
conditions, especially respiratory distress syndrome, surfactant therapy is on the horizon. 相似文献
