Could non-HDL-cholesterol be a better marker of atherogenic dyslipidemia in obstructive sleep apnea?

Background/objectiveObstructive sleep apnea (OSA) is independently associated with dyslipidemia, a surrogate marker of atherosclerosis. Low-density lipoprotein (LDL)-cholesterol is accepted as a major independent risk factor for cardiovascular disease. However, non-high-density lipoprotein (HDL)-cholesterol is a better marker of atherogenic dyslipidemia and recommended as a target of lipid lowering therapy. We aimed to assess the prevalence of atherogenic dyslipidemia, and relationship between OSA severity and serum LDL-cholesterol and non-HDL cholesterol levels in OSA patients.MethodsWe retrospectively evaluated treatment naïve 2361 subjects admitted to the sleep laboratory of a university hospital for polysomnography. All subjects’ lipid profile including total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, and non-HDL-cholesterol were measured.ResultsOut of 2361 patients (mean age 49.6 ± 11.9 years; 68.9% male, apnea-hypopnea index 36.6 ± 28.4/h), 185 (7.8%) had no OSA and 2176 (92.2%) had OSA. Atherogenic dyslipidemia prevalence was high (57–66%) in OSA patients, and especially increased in severe OSA compared to other groups (p < 0.05). Though total and LDL-cholesterol did not differ between those with and without OSA, non-HDL-cholesterol (p = 0.020), and triglycerides (p = 0.001) were higher and HDL-cholesterol levels (p = 0.018) were lower in OSA patients than non-OSA. Non-HDL-cholesterol was significantly correlated with OSA severity (p < 0.001) and hypoxia parameters (p < 0.01), whereas LDL-cholesterol showed no correlation.ConclusionsAtherogenic dyslipidemia is highly prevalent and non-HDL-cholesterol levels are significantly increased, predominantly in severe OSA patients. Non-HDL-cholesterol but not LDL-cholesterol, is significantly correlated with OSA severity and hypoxia parameters. Therefore, it could be better to use non-HDL-cholesterol, which is a guideline recommended target of lipid therapy, as a marker of atherosclerotic cardiovascular risk in OSA patients.     

A comparison of double single suture-button fixation,suture-button fixation,and screw fixation for ankle syndesmosis injury: A retrospective cohort study

Different methods have been used throughout the years for syndesmotic injury but there is no consensus on the ideal treatment. Some methods are expensive and some have more complications. The aim of this study is to compare single suture endobutton with double suture endobutton and screw fixation for syndesmotic injury.Sixty nine patients with syndesmotic injury with fibular fractures whom were treated with a single interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet), a double interosseous suture endobutton system (ZipTight^TM, Zimmer Biomet) and 1 syndesmotic screw (TST, Istanbul, Turkey) were included in this study. Functional and radiological results from patient records between 2015 and 2018 were retrospectively evaluated.Twenty patients were treated with the double interosseous suture endobutton, 23 were treated with the single interosseous suture endobutton, and 26 were treated with traditional AO screw fixation. Three patients from the screw fixation group (11.5%) required revision surgery (P < .05). All the radiologic and clinical outcomes were statistical similar in all 3 groups.Our findings showed that the interosseous suture endobutton system is at least as safe as the screw fixation technique for treatment of syndesmosis joint injuries and can be used as an alternative to the screw method. The interosseous suture endobutton system eliminates the need for a second surgery to remove the hardware, which minimizes the probability of re-diastasis. Since our results showed no statistical difference between single and double interosseous suture endobutton systems, the less costly single endobutton system may be the better alternative.

经穹隆结膜入路埋线法重睑成形术应用探讨

目的:通过分析重睑形成原理,综合比较多种重睑成形的方法,讨论埋线法重睑成形术的优点和可行性。方法:对387例患者行经穹隆结膜入路间断缝合埋线法重睑术。其中88例为其他方法埋线后重睑线消失的患者。结果:手术方法可靠,术后所形成的重睑外形良好,重睑维持时间长。最长随访时间38个月。结论:此方法因符合重睑形成原理,可以充分的将较多的上睑提肌腱膜与上睑皮肤结扎固定、故术后所形成的重睑牢固。且在直视下经穹隆结膜入路,降低了对眼球组织损伤的危险性。是埋线法重睑成形术一种可靠的手术方法。     

压力梯度长袜和间歇充气装置预防恶性肿瘤患者术后下肢深静脉血栓形成的效果

目的 观察单纯应用压力梯度长袜（CS）或与间歇充气装置（IPC）联合使用预防恶性肿瘤患者术后下肢深静脉血栓（DVT）形成的效果及可能的机制。方法 胸科、泌尿外科、肝胆外科恶性肿瘤根治手术患者240例，随机分为4组：对照组、单纯CS组、CS＋IPC全程组、CS＋IPC术后组，每组60例。术后3～8d内行双下肢深静脉超声检查，记录DVT例数及血栓发生部位（大腿或小腿）。随机选择对照组和CS＋IPC全程组各15例患者，分别于术前、切皮后2h及术后24h各采集外周静脉血2ml，测定D-二聚体（D-D）、纤溶酶原激活物抗原（tPA-Ag）、纤溶酶原激活物抑制物（PAI）、血管性血友病因子（vWF）、凝血酶原时间（PT）和活化部分凝血活酶时间（APTT）。结果 术后3-8d对照组、CS＋IPC全程组、CS＋IPC术后组和单纯CS组DVT发生率分别为49．3％、15．0％、23．3％和30．0％（P〈0．05）。所有发生DVT患者中，除CS组发现1例近端DVT外，其余均为远端DVT。发生DVT患者年龄、卧床时间、危险因素个数等与未发生血栓患者相比差异有统计学意义（P〈0．05）。凝血，纤溶指标：与对照组比较，切皮后2h，CS＋IPC全程组vWF升高，D-D、tPA-Ag降低（P〈0．05），术后24h对照组和cs＋IPC全程组间D—D、vWF、tPA-Ag及PAI差异无统计学意义。结论 CS＋IPC全程或术后使用均能降低高危患者术后DVT的发生，其中CS＋IPC全程使用预防效果最好，可能与IPC增加纤溶活性有关。

间断缺血心停搏在冠脉搭桥术中的应用

１９９２～１９９３年间为１８０例冠脉病变的病人施行冠脉搭桥术，全部病人均采用核甙抑制剂利多氟嗪预处理和低温（２８℃）间断缺血心停搏进行术中心肌保护。平均每例病人作冠状动脉端吻合３～４个，每个吻合口用９分钟，主动脉阻断累加时间约２５分钟，体外循环时间９０分钟，术后医院死亡率１．６％（３／１８０），无术后心梗发生。作者认为，冠脉搭桥术的术中心肌保护可采用核甙抑制剂和间断缺血心停搏方法，而不用心肌停搏液。

Practical guidelines for physicians in the management of febrile seizures

Recent studies have shown that adequate medication can prevent the recurrence of febrile seizures (FS). It has also been clarified that the vast majority of, though not all, FS patients follow a benign course. Then, questions arise as to whether or not FS should be prevented, particularly in light of the risks of side effects from drugs. Which kinds of FS can be prevented, if necessary? The guidelines presented here are aimed primarily at helping general practitioners in considering how to manage FS most appropriately. The guidelines stress that judgements should be individualized, while referring to a few specific ‘warning factors’. The guidelines follow a ‘laissez-faire’ principle for the majority of FS cases, whereas intermittent therapy with diazepam and continuous medication with either phenobarbital or valproate are indicated in other limited cases meeting respective definite criteria.
