ObjectiveTo analyze the clinical characteristics of thrombo embolism (TE) in Chinese hypertrophic cardiomyopathy (HCM) patients. MethodsThis study retrospectively analyzed HCM patients admitted to West China Hospital of Sichuan University. The endpoints were defined as a composite of TE events, including ischemic stroke, transient ischemic attack, and peripheral arterial embolization. ResultsA total of 537 HCM patients were included with a median follow-up of 4.2 years. Forty-two patients reached the TE endpoint and the incidence was 1.9%. The annual incidence of TE was approximately 1.1% and 6.6% for HCM patients without/with atrial fibrillation, respectively. The recurrence rate of TE was high (approximately 26.2%). The mean age was 66.4±13.7 years for the first TE, and the incidence of TE was significantly increased at age ≥70 years. ConclusionThe incidence of TE is high in HCM patients, especially in those with atrial fibrillation, and the recurrence rate of TE is also high.
Objective
To investigate the relationship between a body shape index (ABSI) and abnormal inflammation.
Methods
In May 2007, a cross-sectional study was conducted among 651 individuals by random sampling method in an urban community located in Chenghua district of Chengdu. We mainly assessed the relationship between ABSI and abnormal inflammation, which was defined as high sensitive C-reactive protein equal to 3 mg/L or higher.
Results
Logistic regression analysis showed that body mass index (BMI), waist circumference (WC) and ABSI were independently associated with abnormal inflammation. For identifying abnormal inflammation, WC had the best discriminatory power with the area under the receiver operating characteristic curve (AROC) was 0.627 [95% CI (0.564, 0.689)], followed by BMI (AROC: 0.609) and ABSI (AROC: 0.608). In addition, combination with ABSI could improve the discriminatory power of BMI for abnormal inflammation, and AROC increased from 0.609 to 0.646. Combination with ABSI could also improve the discriminatory power of WC for abnormal inflammation, and AROC only increased from 0.627 to 0.631.
Conclusions
In the general Chinese population, ABSI is independently associated with abnormal inflammation, but the discriminatory power is poor, no better than BMI and WC. Furthermore, combination with ABSI can improve the discriminatory power of BMI and WC for abnormal inflammation, especially for BMI. Further studies about ethnic specificities of ABSI are needed.
目的 增加對治療相關性繼發白血病的認識。 方法 報道非霍奇金淋巴瘤治療后2年繼發急性髓細胞白血病M6型1例，結合文獻討論治療相關性白血病的發病機制、治療、預后。 結果 1例73歲非霍奇金淋巴瘤患者接受R（Rituxmab，利妥昔單抗）－CHOP環磷酰胺+多柔比星+長春新堿+潑尼松方案規律化學治療。治療結束24+個月后，經骨髓涂片及細胞免疫分型診斷為急性髓細胞白血病M6型，染色體檢查為：44～48，XY，del（5）（q12q33），-8，-10，der（12）t（4；12）（q11-q12；p13），其一般情況急劇惡化并死亡。 結論 治療相關性白血病的發生可能與烷化劑等化療藥物使用和免疫受損等有關，利妥昔單抗導致第二腫瘤的發生暫時不能除外。治療相關性白血病常伴有復雜染色體核型，其病情發展迅速，治療效果差，生存期明顯縮短。Objective To improve the understanding of secondary therapy-related leukemia. Methods The clinical data of one patient with non-Hodgkin lymphoma which transformed into acute myeloid leukemia M6 2 years after chemotherapy were studied. We discussed the pathogenesis, treatment and prognosis of therapy-related leukemia with literature review. Results A 73-year-old patient diagnosed to have non-Hodgkin’s lymphoma accepted R-CHOP chemotherapy.Two years after the treatment, the disease finally developed into acute myeloid leukemia M6 confirmed by cytogenetics, bone marrow morphology and flowcytometry analysis. The chromosome analysis demonstrated complex karyotypes as 44-48, XY, del (5) (q12q33), -8, -10, der (12) t (4; 12) (q11-q12; p13). His general status deteriorated rapidly and soon after the patient died. Conclusions Occurrence of therapy-related leukemia may be due to the administration of alkylating agents, topoisomerase inhibitors and damage of immune function. Therapy-related leukemia often occurs with complex karyotypes and progresses rapidly with poor treatment response.
【摘要】 目的 分析成都地區中老年居民脈壓（pulse pressure， PP）及脈壓指數（pulse presure index，PPI）與高尿酸血癥（hyperuricemia，HUA）的關系。 方法 利用2007年5月代謝綜合征研究調查資料（共1 061人），依據PP[≤60 mm Hg（1 mm Hg=0.133 kPa）、gt;60 mm Hg]和PPI（≤0.450、gt;0.450）將人群分為正常組及增高組，分析兩組人群尿酸水平及HUA患病率，采用單因素回歸及logistic回歸分析PP及PPI與HUA關系。 結果 ①PP/PPI增高組血漿尿酸水平明顯高于PP/PPI正常組，差異有統計學意義（P=0.000）。②PP/PPI增高組HUA患病率明顯高于PP/PPI正常組，差異有統計學意義（P=0.026、0.027）。③單因素回歸和logistic回歸分析皆提示PP及PPI與HUA呈正相關。 結論 成都地區PP及PPI與血漿尿酸水平關系密切，PP/PPI增高可能是HUA的危險因素。【Abstract】 Objective To evaluate the relationship between pulse pressure (PP), pulse pressure index (PPI) and hyperuricemia (HUA) among middle-aged and aged residents in Chengdu. Methods Based on the level of PP [≤60 mm Hg (1 mm Hg=0.133 kPa),gt;60 mm Hg] and PPI (≤0.450,gt;0.450), We divided the 1 061 middle-aged or aged people into normal PP/PPI group and augmented PP/PPI group. All patients came from the survey for metabolic syndrome study in May 2007. We analyzed the distribution of serum uric acid (UA) and HUA, and analyzed the relationship between PP, PPI and HUA by using single-factor and logistic regression analysis. Results The index of UA in the augmented PP/PPI groups was higher than that in the normal groups with a significant difference (P=0.000). The prevalence of HUA in the augmented PP/PPI groups was statistically higher than that in the normal groups (P=0.026, 0.027). Single-factor and logistic regression analysis showed that PP and PPI were both positively correlated to HUA. Conclusion The abnormalities of PP and PPI are closely related to metabolism disorder in Chengdu, and high level of PP or PPI is probably risk factors for HUA.
Reoperation due to degenerated bioprostheses is an important factor of high-risk thoracic surgeries. In 2020 ACC/AHA guideline, Valve in Valve (ViV) was recommended for high-risk patient instead of surgical mitral valve replacement. This report described a 77-year-old male patient with a failed mitral bioprosthetic valve, evaluated at high risk of surgery, received a transvenous, transseptal transcatheter mitral valve replacement (TMVR). Tracheal intubation was removed at CCU 3 h after surgery without discomfort such as polypnea. The patient was transferred out of the CCU and discharged on the 3rd day. Compared with transapical access, transvenous transseptal access was less invasive, with shorter duration in CCU and hospitalization.
