血小板参数与ACS患者冠脉病变程度的相关性

目的 探讨急性冠脉综合征患者(ACS)血小板参数水平与其冠脉病变严重程度之间的关系.方法 收集ACS患者102例及无缺血性心脏病对照组50例.所有人选者术前空腹采血测定血小板参数.ACS患者行冠状动脉造影及冠脉狭窄程度的评分(Gensini评分).结果 ACS患者MPV,P-LCR较正常对照组显著升高.而PDW,PCT与对照组相比差异无统计学意义.所有ACS患者冠脉病变支数与Gensini评分均随MPV与P-LCR水平的升高而增长.结论 早期监测血小板参数的相关变化对于急性冠脉综合征患者病情的诊断和控制可能具有积极作用.     

冠心病患者空腹血糖、血脂、尿酸和白细胞检测的结果分析

目的研究空腹血糖(FBG)、血脂(BL)、尿酸(UA)水平以及白细胞(WBC)计数与冠心病的关系,探讨冠心病患者空腹血糖、血脂、尿酸与白细胞检测的临床意义。方法收集冠心病患者标本79例(冠心病组),健康体检者标本44例(对照组),测定空腹血糖(FBG)、血脂(BL)、尿酸(UA)、白细胞总数(WBC)以及各类白细胞绝对数。结果冠心病组组FBG、总胆固醇(TC)、甘油三脂(TG)、低密度脂蛋白胆固醇(LDL-C)、UA和中性粒细胞(N)计数显著高于健康对照组(P<0.05),高密度脂蛋白胆固醇(HDL-C)水平显著低于健康对照组(P<0.01)。Logistic回归分析显示:FBG、TC、UA和HDL-C与冠心病密切相关。结论 FBG、TC、UA是冠心病的危险因子,而HDL-C是冠心病的保护因子。     

某市部分食品阪崎肠杆菌污染情况

目的了解某市市售10类食品带染阪崎肠杆菌的数量和程度,从而评估其风险性。方法按照GB 4789.40-2010《食品微生物学检验阪崎肠杆菌检验》和实时荧光PCR法操作规程作定性、定量分析。结果查10类850份食品,有7类54份检出阪崎肠杆菌,检出率为6.4%。39份带菌量在30 MPN/100 g(ml)浓度范围以下,占72.3%;15份带菌量在30MPN/100 g(ml)浓度范围以上,占27.7%。结论小部分糖饼类、冰淇淋、巧克力坚果等食品阪崎肠杆菌带菌量较高,潜在一定的致病风险,要有针对性地加强监督管理。     

Ovarian hyperstimulation syndrome: a review of recent practices

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic adverse event that occurs as a result of ovarian stimulation, particularly in susceptible women. It is caused by an unusually high ovarian response to stimulation and results in enlarged ovaries and fluid shift from intravascular compartment to the third space. Clinical features include abdominal distension, discomfort, ascites, and pleural effusion. There is a risk of thromboembolism and hepatic and renal dysfunction. Ovarian reserve tests can identify patients at high risk of OHSS, allowing targeted preventative measures. High-quality evidence supports the use of GnRH antagonist regimes in women with a high ovarian reserve. GnRH agonist trigger and elective cryopreservation of all embryos further reduce the risk of OHSS. All women at risk of OHSS should have adequate information and access to 24-hour care. Women presenting with possible OHSS should be assessed and investigated to confirm the diagnosis and classify severity. Mild and moderate OHSS can be managed on an out-patient basis, while severe OHSS often needs in-patient care. Principles of management are maintaining intravascular hydration by encouraging fluid intake guided by thirst, close monitoring of fluid balance, prevention of thromboembolic complications, drainage of ascites in selected cases and symptom relief. If conception occurs in the treatment, the course of OHSS is likely to be more severe and protracted.     

Patients' and primary carers' views on clozapine treatment for schizophrenia: A cross-sectional study in Qatar

Subjective views of clozapine treatment among patients with schizophrenia in the Middle East and North African MENA Region have not previously been assessed. Globally, few studies have assessed the views of carers to clozapine treatment. We conducted a cross-sectional survey, using a clinician administered structured interview, of patients with schizophrenia/schizoaffective disorder prescribed clozapine in Qatar, and their primary carers. Participants were asked to rate clozapine against prior their antipsychotic treatment in terms of specific benefits and side effects. Forty-two patients and 33 carers participated in the study. Of the patients, two thirds were male, approximately half were Qatari and the mean age was 33.9 years. Patients and carers rated clozapine as superior to prior antipsychotic treatment on all 7 potential benefits inquired about. The greatest perceived benefit was improved mood. Patients rated clozapine as less likely to cause extrapyramidal side effects but more likely to cause 18 other potential side effects compared to prior antipsychotic treatment, with the greatest difference being for nocturnal salivation, increased appetite, and constipation. Nearly half of patients (48 %) and two thirds of carers (64 %) stated that they would have preferred to start clozapine earlier in their illness. Sixty percent of patients and 37 % of carers regarded the information that they had received from health professionals on clozapine as inadequate. Less than half of patients and approximately-two thirds of carers had adequate knowledge of haematological monitoring for clozapine. Generally, there were significantly positive correlation between patients and carers regarding the overall side effects of clozapine treatment. Likewise, improvement in hearing voices paranoid thoughts correlated with improved quality of life. In summary, the results show that patients and carers appreciate the benefits of clozapine despite its side effects being problematic. The results support clozapine being offered earlier in treatment and services providing more information on clozapine to patients and carers.
