Over 800 Maine residents will be diagnosed with colorectal cancer (CRC) this year, and nearly 300 will die from the disease.
While CRC screening can reduce these rates, it is only among insured populations that screening rates exceed 50%. This project
aimed to reduce barriers to, and increase rates of CRC screening among underinsured and uninsured women, ages 50 years and
over, residing in Cumberland County, Maine. The existing network of the Maine Breast and Cervical Health Program (MBCHP) was
used to reach the target population. A packet containing (1) an offer for no-cost fecal occult blood test (FOBT) screening
and CRC-related educational materials, and (2) a stamped, addressed postcard specifying the woman’s interest in these resources,
was mailed to 300 MBCHP enrollees residing in Cumberland County. Women requesting screening were contacted by phone to further
determine eligibility. Ninety-three women (31%) requested FOBT kits and 29 of these women requested educational materials.
Ten women were ineligible for screening because of previous colonoscopy. Fifty-two completed FOBT kits (63%) were returned;
all were negative. An additional 42 (14%) women requested educational materials only. To reduce the burden of CRC in Maine
and nationally, disparate populations must be reached with efficient and effective screening services. Established networks
are proven means for reaching uninsured and underinsured individuals with education, screening services, and necessary follow-up
care. This project serves as a model for the future development of similar programs statewide and nationally. 相似文献

Teeth adopt a variety of different morphologies, each of which is presumably optimized for performing specific functions during feeding. It is generally agreed that the enamel cap is a crucial element in controlling the mechanical behavior of mammalian teeth under load. Incisors are particularly interesting in terms of structure–function relations, as their role in feeding is that of the ‘first bite’. However, little is known how incisor cap morphology is related to tooth deformation. In the present paper we examine the mechanical behavior of mandibular central incisors in the cercopithecine primate Macaca mulatta under loads similar to those encountered during ingestion. We map three‐dimensional displacements on the labial surface of the crown as it is compressed, using electronic speckle pattern interferometry (ESPI), an optical metrology method. In addition, micro‐computed tomography is used to obtain data regarding the morphology of the enamel cap, which in the M. mulatta lower incisors exhibits missing or very little enamel on the lingual face. The results showed that although compressed along a longitudinal axis, deformation in the incisors mostly occurred in the lingual direction and orthogonal to the direction of the applied load. Both isolated, embedded teeth and teeth in the mandible showed considerable lingual deformation. Incisor deformation in the mandible was generally greater, reflecting the additional freedom of movement enabled by the supporting structures. We show that the association with adjacent teeth in the arch is significant for the behavior of the tooth under load. Finally, loading two teeth simultaneously in the mandible showed that they work as one functional unit. We suggest that these results demonstrate the importance of enamel cap morphology in directing deformation behavior; an ability stemming from the stiffness of the enamel cap overlying the more pliable dentin. 相似文献

ContextThe experience of pain is aggravated among older persons with advanced dementia (OPAD). It is often undetected and therefore untreated because of their limited capacity to identify and report their symptoms. Therefore, it is crucial to improve the pain identification skills of those who know and live with them.ObjectivesTo compare the identification of pain among OPAD between family members and paid care workers and to compare the detection of pain through the use of two common assessment tools.MethodsThis study is a cross-sectional comparison conducted between 82 dyads of informants: the family member of OPAD and the paid care worker, a total of 164 individuals.MeasurementsThe study used two previously validated pain assessment tools for persons suffering from dementia: the Pain Assessment in Noncommunicative Elderly persons tool (PAINE) and Pain Assessment in Advanced Dementia tool (PAINAD), and a general impression question.ResultsBoth family members and paid care workers were able to successfully use both tools. The correlation between family members' ratings and paid care workers' ratings was statistically significant for all the assessments. The correlations between raters were higher when family members lived with the OPAD. The correlations between PAINE and PAINAD scores were moderate and significant, both among family members and paid care workers.ConclusionThis study shows that it is feasible to improve the assessment and identification of pain among OPAD, through the use of validated tools by family members and paid care workers, suggesting the potential to improve quality of care and quality of life of OPAD. 相似文献

Background
Unbearable mental pain, depression, and hopelessness have been associated with suicidal behavior in general, while difficulties with social communication and loneliness have been associated with highly lethal suicide attempts in particular. The literature also links aggression and impulsivity with suicidal behavior but raises questions about their influence on the lethality and outcome of the suicide attempt.Objectives
To evaluate the relative effects of aggression and impulsivity on the lethality of suicide attempts we hypothesized that impulsivity and aggression differentiate between suicide attempters and non-attempters and between medically serious and medically non-serious suicide attempters.Method
The study group included 196 participants divided into four groups: 43 medically serious suicide attempters; 49 medically non-serious suicide attempters, 47 psychiatric patients who had never attempted suicide; and 57 healthy control subjects. Data on sociodemographic parameters, clinical history, and details of the suicide attempts were collected. Participants completed a battery of instruments for assessment of aggression–impulsivity, mental pain, and communication difficulties.Results
The medically serious and medically non-serious suicide attempters scored significantly higher than both control groups on mental pain, depression, and hopelessness (p < .001 for all) and on anger-in, anger-out, violence, and impulsivity (p < .05 for all), with no significant difference between the two suicide attempter groups. Medically serious suicide attempters had significantly lower self-disclosure (p < .05) and more schizoid tendencies (p < .001) than the other three groups and significantly more feelings of loneliness than the medically non-serious suicide attempters and nonsuicidal psychiatric patients (p < .05). Analysis of aggression–impulsivity, mental pain, and communication variables with suicide lethality yielded significant correlations for self-disclosure, schizoid tendency, and loneliness. The interaction between mental pain and schizoid traits explained some of the variance in suicide lethality, over and above the contribution of each component alone.Conclusions
Aggression–impulsivity and mental pain are risk factors for suicide attempts. However, only difficulties in communication differentiate medically serious from medically non-serious suicide attempters. The combination of unbearable mental pain and difficulties in communication has a magnifying effect on the risk of lethal suicidal behavior. 相似文献7.

Background
To provide quality care to the growing number of older patients, primary care physicians (PCPs) will require support from geriatric specialists. Multidisciplinary comprehensive geriatric assessment (CGA) has been found to improve outcomes in older people. This study explored the contribution of CGA to the management of older patients by their PCPs; PCP attitudes to CGA; and PCP satisfaction with CGA.Methods
Two hundred PCPs in an Israeli Preferred Provider Organization were interviewed as part of an evaluative study of the contribution of a national outpatient CGA program to older patients, their families and physicians.Results
The main reasons for referral to CGA were cognitive impairment and rapid functional decline. Three domains described the contribution of CGA to PCPs: medical treatment, support in counseling patients, and treatment of cognitive impairment. About 69% of PCPs definitely agreed that CGA more fully addressed the physical, mental and social needs of patients than other consultative clinics. About half were very satisfied with the CGA staff’s attitudes to patients, their families and to the PCP.Conclusions
CGA contributed significantly to the care provided to older patients by PCPs. The expansion of CGA services deserves consideration.9.
