We examined data from a prospective cohort study of patients undergoing spinal surgerybetween January 1st 2003 and December 31st 2004 at two academic hospitals: a universitybased medical center, and a county hospital serving as the only Level I trauma center in alarge multi-state area. All patients were prospectively followed for the for at least 2 yearsafter their surgery using surveillance methods as previously described by Mirza et al.[10]All patients were followed with institutional review board approval from the University ofWashington Medical Center. Detailed information regarding patient demographics, medicalco-morbidity, surgical invasiveness, and adverse occurrences were obtained prospectivelyusing previous published methods.[10, 11]

We excluded all patients who did not undergo cervical spine surgery. We also excludedpatients younger than 18 years of age, those with missing surgical invasiveness data andthose with a surgical invasiveness index that was either missing or equal to zero as theseincluded patients who did not actually have spinal decompression or fusion (closed casting,placement of halo) (Figure 1).

The identification and quantification of risk factors for complication after spine surgery is 股票入门K线图基础知识 ofparamount importance to the patient and the clinician. In addition to its obvious importancefor patient safety, risk factor information becomes critical as health care policy makersimplement and enforce `quality' metrics.

Prior 股票入门K线图基础知识 studies have reported complications after spine 股票入门K线图基础知识 surgery using different models. Theseinclude analysis of Medicare, Workmen's Compensation, National Inpatient Sample[1–3],and retrospective hospital chart review data[4–8]. While there are respective strengths andweaknesses of these studies, the largest 股票入门K线图基础知识 weakness is that these reports do 股票入门K线图基础知识 股票入门K线图基础知识 not account for theeffect of surgical invasiveness. It is intuitive that the occurrence 股票入门K线图基础知识 of a medical complicationafter surgery is a function of the patient's baseline medical status and the extensiveness ofsurgery. While some studies differentiate arthrodesis from non-arthrodesis surgeries, or

instrumented vs. non-instrumented fusions, it is difficult to discern how much additional riskthere is based on number of levels decompressed, arthrodesed and instrumented fromvarious approaches.

The Spine End Results Registry 2003–2004 is a prospective cohort of all patients

undergoing spinal surgery at 股票入门K线图基础知识 the University of Washington Medical Center and HarborviewMedical Center. Detailed information regarding patient demographics, medical co-morbidity, surgical invasiveness, and adverse occurrences were obtained prospectively usingprevious published methods.[10, 11] We utilized a previously validated scoring system forsurgical invasiveness score[10] that assigned point values for each level decompressed,arthrodesed, and instrumented from an anterior or posterior approach.

The purpose of the present study is to assess the relative risk of numerous patient specificand surgical factors on peri-operative medical complications (cardiac, pulmonary, gastro-intestinal, hematological, renal, neurological, death) using univariate 股票入门K线图基础知识 and multivariate logbinomial analysis. We hypothesized that age, diabetes, revision surgery, medical co-morbidity, and surgical invasiveness were significant risk factors for peri-operativemorbidity after cervical spine surgery.

想学炒股,要怎么开始?

复利系数表

复利收益=投入*长期收益率*时间

我们把投资当做一场长跑来看。

投入决定投资的起跑线,长期收益率决定前进的速度。如果两项都为正,时间越长当然最终到达的终点越远。

投资是按百分比产出的,所以收益绝对值当然要跟初始投入挂钩,这是非常客观的。(投资投资,没有资投的毛?)

*如果是以很直白的赚钱改善生活,考虑到时间、精力、机会成本,我认为个人本金的持续总投入最好超过6位数,否则投资这个事情对个人经济状况的改善意义不大。

*以我自己为例,我刚毕业时初始的投入只有每个月几千块的工资收入,即使我初期很努力很节俭滚雪球速度也很快,还是用了两年多才攒到第一勺金(30w),在此之前我是没有从投资中拿出哪怕一分钱反哺生活的。

如果你足够聪明努力又幸运,投资是有可能让你慢慢变富的。但投资绝不可能让你一夜暴富。

对于初学者来讲,一般都会很着急看到一个结果,恨不得天天抓涨停。对于老鸟来讲,时间成本的重要程度会低很多,确定性才是最重要的。毕竟搞对一次搞个30%-50%一年已经爽歪歪了,搞错了退一步你需要进三步才能回到原来的节奏。

2.2 投资中的自我定位

在上一小节的拆解中我已经提到了,我们每个人都应该定义好投资在自己生活中的位置。我认为这是投资学习中的第二等大事

付出每天2个小时看抖音吃鸡撩汉把妹的时间换成投资学习和复盘,你愿意吗?

再看一下如果你手中只有几万块本金,达到年化收益15%,付出这些一年也就多赚几千块(还不一定)。你还觉得值得吗?

如果运气不好这笔钱一开始就亏掉30%(很有可能),会严重影响你的生活和心情吗?

2.3 体验玩家、休闲玩家、职业玩家

3、打造可持续学习的信息环境

在我的理念里,信息环境是默默决定我们认知积累最重要的因素

3.2 注意力管理——打造信息环境的实质

我自己比较有心得的解决方案是注意力管理,总结给大家大致包括以下几个步骤:

简而言之就是根据自身日常习惯,有意识的打造“注意力界面”,将高价值信息源放在最显眼、最方便的地方,占据注意力。让你的手机、电脑各种日常timeline充斥着高价值信息,需要的信息可以最快速度一键找到。

有效的工具:便签、置顶、收藏、标星、应用首页、通知管理、特别关注、个人导航等

3.3 投资,从获取信息出发

正向顺序就是:获信息=>提炼逻辑=>筛选标的。

从生活中获取交易机会是一个特别有效的办法,我举过一个自己特别印象深刻的生活中发现投资机会的案例。

那是在2012年的一天,我正在路边等公交车的时候,突然抬眼看到一个广告牌子写着“怕上火喝加多宝”,脑子马上像过电一样发现一个投资机会——广州药业。

要知道,当时所有的广告语都是“怕上火喝王老吉”,绝大多数人根本不注意什么加多宝。

但这个时候为什么突然出现这么个广告语?

真相只有一个——加多宝公司预感自己要输掉官司,在匆忙做品牌转移!

果不其然,法院很快判王老吉品牌归还广药,当时的广州药业和合并对标标的白云山两只股票在短时间内上涨了50%以上。

能够发现这个标的其实非常简单,就两个原因。

①我知道王老吉的品牌是广药集团的,他们在和加多宝打官司。

②我知道通过加多宝给自己找后路推断出加多宝大概率输掉官司。

前者属于信息和知识的日常积累,后者属于信息敏感性训练。

获取信息,提炼逻辑,筛选标的

3.4 信息获取——构建信息渠道与知识积累体系

可持续信息体系=1张网+1条线+N个重要节点+多维度外部链接

A、1张网——网络化知识体系

参考示例

B、1条线——7*24即时信息流

参考示例

C、N个重要节点——高质量信源

D、多维度外部链接——投资交流圈

四、初步感知股市

1、股市是什么:股与市的两种思维

实际上,你在股市里生存,需要分别拥有两种思维。大体上一半是研究员思维,用于琢磨企业划算不划算(更接近于投资);另一半是交易员思维,用于与别的投资者博弈争取占便宜(更接近于投机)。
