An evaluation of symptom domains in the 2 years before pregnancy as predictors of relapse in the perinatal period in women with severe mental illness

BackgroundSymptoms may be more useful prognostic markers for mental illness than diagnoses. We sought to investigate symptom domains in women with pre-existing severe mental illness (SMI; psychotic and bipolar disorder) as predictors of relapse risk during the perinatal period.MethodsData were obtained from electronic health records of 399 pregnant women with SMI diagnoses from a large south London mental healthcare provider. Symptoms within six domains characteristically associated with SMI (positive, negative, disorganization, mania, depression, and catatonia) recorded in clinical notes 2 years before pregnancy were identified with natural language processing algorithms to extract data from text, and associations investigated with hospitalization during pregnancy and 3 months postpartum.ResultsSeventy-six women (19%) relapsed during pregnancy and 107 (27%) relapsed postpartum. After adjusting for covariates, disorganization symptoms showed a positive association at borderline significance with relapse during pregnancy (adjusted odds ratio [aOR] = 1.36; 95% confidence interval [CI] = 0.99–1.87 per unit increase in number of symptoms) and depressive symptoms negatively with relapse postpartum (0.78; 0.62–0.98). Restricting the sample to women with at least one recorded symptom in any given domain, higher disorganization (1.84; 1.22–2.76), positive (1.50; 1.07–2.11), and manic (1.48; 1.03–2.11) symptoms were associated with relapse during pregnancy, and disorganization (1.54; 1.08–2.20) symptom domains were associated with relapse postpartum.ConclusionsPositive, disorganization, and manic symptoms recorded in the 2 years before pregnancy were associated with increased risk of relapse during pregnancy and postpartum. The characterization of routine health records from text fields is relatively transferrable and could help inform predictive risk modelling.     

精神分裂症患者5年内复发再入院情况分析

目的调查分析精神分裂症患者5年内复发再入院情况。方法采用回顾性分析法了解患者在5年内复发再入院情况,比较复发入院者和未复发者基本情况的差异。结果5年内患者复发入院率达33．70％,患者性别（X2：4．84,P=0．028）、年龄（X2=13．89,P=0．ooo）、婚姻（X2=11．31,P=0．001）、受教育程度（r=4．83,P=0．028）对其复发住院情况有显著影响。结论精神分裂症患者有较高的复发入院率,应及早进行复发干预。     

Postoperative stability of conventional bimaxillary surgery compared with maxillary impaction surgery with mandibular autorotation for patients with skeletal class II retrognathia

We aimed to compare the postoperative stability of conventional bimaxillary surgery (with bilateral sagittal split osteotomy) with that of maxillary impaction surgery (with mandibular autorotation without bilateral sagittal split osteotomy) in patients with skeletal class II retrognathia. Patients were assigned to have conventional bimaxillary surgery (conventional group, n = 6) or mandibular autorotation (experimental group, n = 7). Measurements were made using serial lateral cephalometric radiographs taken immediately preoperatively (T0), immediately postoperatively (T1), and one year later (T2) to assess the variation in operative change (T1-T0) and relapse (T2-T1). There was no significant difference in median (range) surgical change in the anterior movement at point B (conventional group, 4.5 (3.0–11.0) mm; experimental group 4.1 (2.1–6.4) mm). However, there was a significant difference in median (range) surgical posterior movement relapse at point B (conventional group −1.7 (−2.3 to −0.5) mm; experimental group −0.6 (−1.0 to 1.0) mm; p = 0.032). Mandibular advancement with mandibular autorotation is therefore a more stable procedure than mandibular advancement with bilateral sagittal split osteotomy in patients with skeletal class II retrognathia.     

阿司匹林、氯吡格雷不同联合阿托伐他汀钙治疗对短暂缺血性脑缺血发作患者住院期间复发进展率的影响

目的： 分析短暂性脑缺血发作（TIA）患者中,应用阿司匹林、氯吡格雷联合他汀类药物治疗的效用。方法： 选取在其院接受治疗的116例TIA患者,收治的时间为2017年3月-2019年10月,按照不同的治疗方法将所有的患者分为3组,其中A组32例（给予阿司匹林+阿托伐他汀钙片治疗）,B组20例（给予氯吡格雷+阿托伐他汀钙片）,C组64例（给予氯吡格雷+阿托伐他汀钙片+阿司匹林治疗）。将3组治疗后的复发进展率、TIA发作时间、血小板计数、凝血功能、治疗效果以及不良反应发生情况进行对比。结果： 经分析,B组、C组的治疗总有效率均高于A组,差异有显著性意义（P<0.05）,C组的治疗总有效率高于B组（P<0.05）;经重复测量方差分析,3组患者治疗前后不同时间的PT值比较,差异无显著性（P>0.05）;3组患者治疗前后不同时间的APTT水平比较,差异具有显著性（P<0.05）;经两两比较,C组的PT水平明显低于A组和B组（P<0.05）;经重复测量方差分析,3组患者治疗前后TIA发作时间比较,差异具有显著性（P<0.05）。治疗后,C组的复发进展率较A组和B组低（P<0.05）;3组用药后的不良反应发生率相比不具有显著性（P>0.05）。结论： 给予阿司匹林+阿托伐他汀钙片+氯吡格雷联合应用于TIA时,可以发挥协同作用,改善凝血功能,抑制血小板的聚集,机体状态改善明显,进而降低了进展复发率,且用药安全性高。     

Phenotype classification using the combination of lung sound analysis and fractional exhaled nitric oxide for evaluating asthma treatment

Background

We report the utility of combining lung sound analysis and fractional exhaled nitric oxide (FeNO) for phenotype classification of airway inflammation in patients with bronchial asthma.We investigated the usefulness of the combination of the expiration-to-inspiration sound power ratio in the mid-frequency range (E/I MF) of 200–400 Hz and FeNO for comprehensively classifying disease type and evaluating asthma treatment.

结直肠癌患者血清肿瘤标志物联合检测的临床意义

目的探讨血清肿瘤标志物联合检测在结直肠癌(CRC)患者病情监测中的临床意义。方法 116例CRC患者根据不同肿瘤分期分为Ⅰ~Ⅱ期组50例和Ⅲ~Ⅳ期组66例,比较2组血清肿瘤标志物水平。同时比较化疗后12个月和24个月时复发转移与未复发转移者血清肿瘤标志物水平差异。结果Ⅰ~Ⅱ期组患者血清癌胚抗原(CEA)、糖链抗原19-9(CA19-9)和CA242水平均显著低于Ⅲ~Ⅳ期组,差异有统计学意义(P0.05);2组血清甲胎蛋白(AFP)、CA724水平比较,差异无统计学意义(P0.05);化疗后12个月,复发转移与无复发转移患者血清CEA、CA199、CA242、CA724水平比较,差异有统计学意义(P0.05);2组血清AFP水平比较,差异无统计学意义(P0.05);化疗后24个月,复发转移与无复发转移患者血清CEA、CA199、CA242、AFP、CA724水平比较,差异有统计学意义(P0.05)。结论血清肿瘤标志物联合检测在评估CRC患者病情、监测化疗后是否复发转移上具有一定临床价值。     

Infection of donor lymphocytes with human T lymphotrophic virus type 1 (HTLV-I) following allogeneic bone marrow transplantation for HTLV-I positive adult T-cell leukaemia

Summary. Human T lymphotrophic virus type 1 (HTLV-I) associated leukaemia has a poor prognosis even with chemotherapy. We describe a patient with adult T-cell leukaemia treated with allogeneic bone marrow transplantation from an HTLV-I negative identical sibling donor. During follow-up after bone marrow transplantation, HTLV-I could be repeatedly isolated inspite of anti-viral prophylaxis. The patient died of an acute encephalitis and HTLV-I could be detected in autopsy material from the brain. By a PCR-based technique using short tandem repeats (STRs) it was shown that the patient's haemopoiesis was of donor origin. This shows the infection of donor cells in vivo by an aetiological agent which has been implicated in the leukaemogenic process for adult T-cell leukaemia.
