Diastolic heart failure

Diastolic heart failure is predominantly a disease of the elderly: at the age of 70 years, almost half of all patients with heart failure have diastolic heart failure. Hypertension and obesity are common underlying disorders in patients with diastolic heart failure. Patients with diastolic heart failure have an equal, or only slightly better, prognosis in terms of mortality compared to patients with systolic heart failure. Echocardiography can distinguish diastolic heart failure from systolic heart failure. Patients with heart failure and a normal ejection fraction almost certainly have a diastolic dysfunction. There is a lack of reliable data about the optimal medicinal treatment strategy for patients with diastolic heart failure. Angiotensin-converting enzyme (ACE) inhibitors, beta-blockers, and (non-dihydropyridine) calcium antagonists have therapeutic potential. Digoxin may be contraindicated.

肺结核并发呼吸衰竭50例临床研究

目的：分析肺结核并发呼吸衰竭50例患者的临床疗效。方法：对50例肺结核并发呼吸衰竭患者采取抗结核治疗和呼吸衰竭的相关治疗。结果：50例患者中,42例呼吸衰竭有好转,8例死亡。死亡的患者中,3例死于呼吸衰竭,2例死于循环衰竭,3例死于肝衰竭。血气分析表明,患者治疗前后PaCO2和PaO2比较差异均具有统计学意义（P〈0．05）。结论：肺结核并发呼吸衰竭,死亡率较高,一旦发生,应及时进行正确治疗,减少死亡例数,因此肺结核控制并发症至关重要。     

Clinical characteristics of nursing home residents hospitalized with heart failure

OBJECTIVE: The purpose of this retrospective study was to describe the clinical characteristics of heart failure among nursing home residents hospitalized with heart failure and determine the validity of dyspnea at rest in the diagnosis of heart failure. METHODS: Subjects were nursing home residents hospitalized with a diagnosis of heart failure. Data on demographic and various admission characteristics were collected by chart abstraction. Proportions of patients presenting with various symptoms and signs of heart failure have been described. The diagnosis of heart failure was confirmed using modified Framingham criteria. The sensitivity, specificity, and positive predictive value of the symptom of dyspnea at rest in the diagnosis of heart failure in nursing home residents hospitalized with heart failure were then estimated. RESULTS: Patients (N = 98) were elderly, predominantly female and about one-fifth African-American. Dyspnea at rest was the presenting symptom of 85 (87%) patients. Sixty-eight (69%) patients met modified Framingham criteria for the diagnosis of heart failure. Dyspnea at rest had a sensitivity of 91%, specificity of 23%, and predictive value positive of 73% for diagnosis of heart failure. CONCLUSION: Dyspnea at rest was the most common symptom among this cohort of nursing home residents hospitalized with heart failure and has a potential to play a useful role in the diagnosis of heart failure in these patients.     

Contraceptive failure in China

This study examines patterns and differentials of contraceptive failure rates by method and characteristics of users, using the Chinese Two-per-Thousand Fertility Survey data. The results show that contraceptive failure rates for modern methods including sterilization are some of the highest in the world. The first year failure rates are 4.2% for male sterilization, 0.7% for female sterilization, 10.3% for IUD, 14.5% for pill, and 19.0% for condom. There are also some differentials in contraceptive failure rates by users' sociodemographic and fertility characteristics. Contraceptive failure rate declines with women's age for all reversible methods. Rural women have higher sterilization, IUD, and condom contraceptive failure rates than urban women. Women with two or more children have a higher failure rate for sterilization methods but have lower failure rates for other methods.     

非意愿妊娠原因及对策的研究

为分析和探讨导致非意愿妊娠的原因,降低人工流产率,促进广大育龄妇女生殖健康提供科学依据,采用以医院为场所的描述性流行病学研究方法,1996年3月～1996年5月,在郑州市8家医院妇产科门诊,对来寻求计划生育服务的妇女采用填写调查表的方式进行调查。共调查1557例,其中行人工流产(包括手术流产和药物流产)者1099例,平均每例1.22次。流产者中38.8％是由于未采取避孕措施而致意外妊娠,61.2％为避孕失败造成的。55.6％能清楚记得避孕失败时间。通过对人流者既往避孕史的研究,发现有避孕失败史者占51.6％,其中避孕套失败最多,占37.0％;其次是安全期失败,占23.0％;宫内节育器失败居第三位,占21.0％。避孕失败妇女的年龄主要分布于性生活旺盛年龄组(21～29岁),占70.3％。结果表明导致非意愿妊娠的根本原因是避孕观念淡薄,避孕知识(包括紧急避孕知识)匮乏。建议对不同人群进行侧重点不同的有关避孕知识教育,并加强避孕药具的质量管理。
