Clinical effects of growth hormone on bone: a review

Growth hormone (GH) stimulates bone turnover. Deficiency of GH due to hypopituitarism is related to low bone mineral density and increased fracture risk. GH substitution increases and thus normalizes bone mineral density in these patients, which is one of a number of arguments for GH substitution in hypopituitarism. In contrast, a possible therapeutic use of GH in idiopathic osteoporosis and glucocorticoid-induced osteoporosis is speculative and not established. Reduction of osteoporosis risk is an argument brought up for a use of GH in healthy elderly persons (anti-aging medicine). However, since only very limited data are available yet, this cannot be based on scientific evidence, and there are important concerns about the safety of use of GH in healthy elderly persons.     

从全球人口百年(1950～2050)审视我国人口国策的抉择

基于“人口众多”这一基本国情,我国自20世纪80年代前后采取了严格控制人口增长的政策。对于这一政策应科学、全面地衡量其利害得失。文章利用全球人口资料和我国历次人口普查及人口预测资料,从人口规模、结构的发展变化作实证研究。最终认为,我国的人口国策是利大于弊。     

Collaborating with families in differential responses: practitioners' views

Child protection authorities in many countries are concerned with reducing the rates of investigations and with diverting at‐risk families from the child protection service system. In several countries, differential responses have been introduced into child protection law providing service providers with some choice between investigative or family support pathways, depending upon the level of risk posed in the circumstance. In this paper, we report on a study into a form of differential response known as Intervention with Parents' Agreement introduced in Queensland, Australia, in 2005. A unique feature of this differential response is that it occurs after an initial child protection investigation, although it does provide child protection services with options for providing supportive interventions to at‐risk families to prevent the further escalation of concerns. In this paper, we analyse practitioners' perceptions of factors that inhibit and promote implementation of the Intervention with Parents' Agreement. Drawing upon interviews with 25 practitioners, we identify factors that become important for securing participation after an initial investigation has occurred. We discuss the implications for the development of differential responses in child protection service systems.     

A Study of An Alternative School for Pregnant and/or Parenting Teens: Quantitative and Qualitative Evidence

In response to multiple problems faced by pregnant and parenting teens, many alternative school-based comprehensive programs have been established throughout the United States. By collecting data from a sample of enrollees of such a school-based comprehensive program and comparing them with data collected from a sample of non-enrollees, the present study systematically evaluates the program. The results of the study seem to suggest that the program participants were more likely to have higher educational aspiration, better reproductive health outcomes, higher contraceptive use, and more breast-feeding practice and intention than those of their non-participating counterparts. The implications of the study findings for comprehensive school-based program for pregnant and/or parenting teens are discussed.Ruhul Amin is a Senior Fellow at the Center for Health Disparities Solutions and Senior Research Scientist in the Institute for Urban Research, Morgan State University, Baltimore, MD 21239.

Interval estimates for variance components

A new approach to inference on variance components is propounded. This approach not only gives a new justification for Fisher's fiducial, distribution for the “between classes” component, but also leads to a new distribution for the “within classes” component. This latter distribution is studied, and has some intuitively very reasonable properties. Numerical results are given.     

Patients' Evaluations of Gynecologic Services Provided by Nurse Practitioners

Abstract

The development, operating principles, and users' evaluations of a broad-based gynecologic program emphasizing effective birth control on a university campus are discussed. A major feature that is explored is the use of nurse practitioners as the primary service providers. The forces that resulted in the formation of the program and the methods used to enhance its effectiveness are described. The evaluations of 3,527 users over a three-year period are indicated by summarizing responses to a questionnaire covering the following topics; whether providing such a service was helpful, likelihood of arranging for the service elsewhere if unavailable at the health center, attitudes of staff, medical procedures used, availability of services, and the opportunity to thoroughly discuss concerns. The evaluations were seen as extremely supportive of both the program and the use of nurse practitioners in this setting.     

Variables Affecting Patient Satisfaction with Health Care Services in the College Health Setting

Abstract

Patient satisfaction with health care services is an important factor in health care delivery. It will significantly influence whether or not a patient seeks medical care, complies with prescribed treatment, and/or maintains a continuing relationship with a medical practitioner.

A survey questionnaire, relating patient satisfaction with a number of variables identified through a literature review, was mailed to a random sample of 500 students utilizing Student Health Service (SHS) at Kent State University (KSU) during the five week study period. The data obtained would be utilized to help with planning future health care services and staff inservice education programs.

The findings of this survey indicate that patient satisfaction has a statistically significant correlation with perceived technical competence of the practitioner and perceived adequacy of the interpersonal aspects of the practitioner-patient relationship. A significant relationship did not exist between satisfaction and expectations the patient holds of the practitioner's role performance. A statistically significant relationship was found to exist between receiving health information/education related to diagnosis, prognosis, and treatment plan and satisfaction with health care services. This relationship did not hold for health information/education related to activity restrictions or preventive measures. The study also revealed that time waited during the medical care encounter was inversely related to satisfaction. Last, stepwise regression found that perceived technical competence of the practitioner was the most important variable influencing patient satisfaction with health care services.

This study provides data about factors important to personal satisfaction with health care services for a selected group of college students.
