In June 2002, the UN Theme Group on HIV/AIDS in China published a comprehensive situation analysis and needs assessment of the HIV/AIDS epidemic in the People's Republic of China (PRC). The report, entitled "HIV/AIDS: China's Titanic Peril", also describes and analyzes current HIV/AIDS legislation and policies. It notes that "laws and regulations that are based on fear and prejudice have contributed to fuelling the epidemic instead of curbing it." The report observes that the targets and goals established in China's five-year Plan of Action (2001-2005) are not consistent with the commitments endorsed in June 2001 at the United Nations General Assembly Special Session on HIV/AIDS. It states that the Plan "continues to present HIV/AIDS as a medical problem, and fails to understand the epidemic as a broader development issue." Even where laws could assist, enforcement remains a huge challenge. For example, in 1998 the National People's Congress passed a law prohibiting commercial blood donations for medical purposes. Nonetheless, the illicit and unregulated blood trade, which has rapidly accelerated the spread of HIV infection in China, has continued. When the alarm was sounded by Dr. Wan Yanhai, coordinator of the AIZHI (AIDS) Action Project, the government response was to arrest him. In the following article, Nick Young, editor of China Development Brief, reviews the findings of three studies commissioned by the United Nations Development Programme (UNDP) on the role of the law in response to HIV/AIDS.  相似文献

Ketosis occurs in ketoacidosis or malnourishment. When either is suspected in relation to a death, it may be important to analyze for ketosis at autopsy. We encountered a case where starvation was suspected in a deceased nursing home resident, where the body had been embalmed prior to autopsy. Gas chromatography (GC) was unable to separate acetone from formaldehyde, a component of embalming fluid. The Acetest is a simple test that can detect acetone and acetoacetate in body fluids. We validated the Acetest with GC on vitreous. The Acetest and GC were consistent except at very low levels of acetone or acetoacetate. The sensitivity of the Acetest for acetoacetate in vitreous was 10 mg/dL, consistent with early starvation. Significant interference from embalming fluid did not occur. The Acetest was negative in the described case. The Acetest is a simple and useful test for the detection of ketosis in embalmed autopsies.  相似文献

Prior research has indicated that pubertal development and peer associations are important determinants of adolescent smoking behavior. However, more remains to be learned about why these variables matter or how they may be related to one another in ways that lead to the initiation of smoking. Using contractual data from the National Longitudinal Study of Adolescent Health, we consider the relationship between early pubertal development and associations with close friends who smoke, and smoking initiation among male youths. The results of the study reveal a link between advanced pubertal development and the initiation of smoking among boys, but we discover that the effect is indirect, mediated by a greater propensity of sexually mature males to forge friendships with peers who smoke. We also find that this propensity is greatest among the youngest adolescents in the sample, suggesting that the age of the respondent conditions the effects of pubertal development on the formation of friendships with peers who smoke.(Ph.D., The University of Texas at Austin), is an Assistant Professor at Washington State University at Vancouver. Her areas of interest include juvenile delinquency and substance abuse.(Ph.D., Rutgers: The State University of New Jersey) is an Assistant Professor at Westfield State College. Her area of interest is adolescent identity development.(Ph.D., The University of Texas at Austin) is an Associate Professor at the University of Portland. His areas of interest include biosocial models of adolescent problem behavior.  相似文献

Hair samples are useful as a matrix for drug testing because drugs can be detected in hair for longer periods than in blood or urine. The authors report a prospective comparison of the detection of cocaine and cocaethylene in routine postmortem biologic specimens to the detection of cocaine and cocaethylene in hair. The authors collected hair samples from various areas of the head in 53 autopsy cases, prepared them, and analyzed them by gas chromatography/mass spectrometry (GC/MS) for cocaine and cocaethylene. The authors compared the results of hair analysis with the results of toxicologic analysis performed on routine postmortem samples by enzyme multiplied immunoassay technique and GC/MS. Cocaine was found in either biologic fluids or in hair in 16 of 53 samples tested. Nine samples were positive for cocaine in both biologic fluids and hair. Five samples contained cocaine only in biologic fluids, and two contained cocaine only in hair. Cocaethylene was present in two cases. Drug screening of hair provides additional information in some autopsy cases, but the authors have not made hair analysis a routine practice. It may prove useful to save hair samples in all cases for later analysis if warranted by additional history or autopsy findings.  相似文献

Hypertrophic cardiomyopathy (HCM) is a disease process which results in a large, heavy heart, with hypertrophy of the interventricular septum (IVS) and left ventricle. HCM accounts for a significant number of cases of sudden cardiac death each year, most infamously in young athletes. The prevalence of the disease has increased over the past several years due to advances in clinical diagnosis and molecular genetic studies. Over this same period, new forms of treatment also have emerged. One such treatment is alcohol septal ablation (ASA). ASA is a procedure performed by a cardiologist, via cardiac catheterization, by injecting pure ethanol into selected arteries which supply the IVS, resulting in a targeted myocardial infarction. This infarct then retracts and forms a scar, decreasing the outflow obstruction and improving the patient's clinical symptoms.The authors report 2 cases of death following ASA treatment of HCM. The first, a 56-year-old male, had his ASA procedure 10 days prior to death. The second decedent, a 76-year-old female, had her procedure only 30 hours before death. These case reports are followed by a discussion about HCM, including pathology, treatments, and treatment-related pathology, before closing with a discussion about death certification in the cases presented and therapy-related deaths in general.  相似文献

The purpose of this article is to use the ideas of path dependency to understand why policies implemented by governments for health care in England were and are suboptimal in terms of the control of total costs, the equitable distribution of hospital services, and efficiency in delivery. We do this by relating the economic logic of achieving these objectives to the political logic of a state-hierarchical system in which ministers are accountable for the effects of policies and doctors largely decide the supply and demand of health care. The initial policy path of the National Health Service (NHS) controlled costs but lacked systems to achieve equity and efficiency in the funding of hospitals. Policies were introduced to achieve equity, but not efficiency, in the 1970s. The Thatcher government sought efficiency through a budgetary squeeze in the 1980s, which culminated in the NHS funding crisis of 1987 - 1988. The result was the policies of the NHS internal market, which promised efficiency by introducing a purchaser-provider split and a system of provider competition in which money would follow the patient. These promises justified an injection of extra funds for three years, but only a pallid model of the internal market was implemented. The Blair government abandoned the rhetoric of competition but maintained the purchaser-provider split and continued to constrain total NHS costs, which resulted in the funding crisis of 1998 - 1999. Current policies are to substantially increase spending on health care and reintroduce a system of provider competition in which money will follow the patient.  相似文献

A 29-year old female with a history of depression was found dead in a hotel room. The death scene investigation found empty pill bottles and an empty liter bottle of wine. Metaxalone, a centrally acting muscle relaxant, along with citalopram, ethanol, and chlorpheniramine were identified in the postmortem samples and quantitated by gas chromatography-mass spectrometry. The concentration of metaxalone in femoral vein blood was 39 mg/L. The heart blood concentration was 54 mg/L. Femoral vein blood concentrations of citalopram and chlorpheniramine were 0.77 mg/L and 0.04 mg/L, respectively. Ethanol levels were 0.13 g/dL in vitreous and 0.08 g/dL in heart blood. Other tissue samples were also analyzed. The authors consider the metaxalone concentrations toxic and potentially fatal. The citalopram concentrations were lower than those reported in fatal cases for this drug alone. Death was ascribed to polydrug abuse/overdose with metaxalone a major contributor. This represents the first reported case to our knowledge in which a metaxalone overdose significantly contributed to death.  相似文献

This note examines the case of a group of gay men who, having engaged in consensual sexual acts together, became known as the `Bolton Seven' following their conviction in 1998 for offences of buggery and/or gross indecency. More particularly the note scrutinises the implications of the ages of the participants (one of whom, at 17 , was unable to give lawful consent to sexual intercourse with a man) in the light of the enactment of Part I of the Sex Offenders Act 1997 which introduces a system of compulsory registration by some convicted and cautioned sex offenders with the police (including men convicted of, or cautioned for, buggery or gross indecency). The note explores the justification for inclusion of these offences within the remit of the1997 Act together with the cultural construction of gay men as predatory and as constituting a risk to younger members of society. It also analyses some of the effects of the registration requirement in terms of it constituting a potential violation of fundamental rights such as equality and respect for private life. This discussion is located particularly within the context of the jurisprudence of the European Court of Human Rights and the introduction of the Human Rights Act 1998 in the U.K.. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献
