Playdough Surgery 🔪- Colectomy (colon removal) and Colostomy Creation - aka Hartmann Procedure
.
“Do all people only poop out of their butt? Can the poop come out from anywhere else?” - my 3yo wondered aloud one day.
.
I had to take this opportunity to tell him about the lifesaving surgeries that result in the creation of an opening in the abdomen (called a stoma) to release waste products. Did you know? More than 1 million people in North America live with a permanent ostomy, and some 100,000 new ostomy surgeries are being performed each year.
.
Thankfully, most colon surgeries can be completed without needing an ostomy. But our patient had an advanced, perforated colon cancer that required emergent removal (sometimes these are reversed later and reconnected when the patient is feeling better). My little guy couldn’t wait to stick his hand 👋🏻 into the abdomen and pull out the sigmoid colon like the surgeons in the videos we watched.
.
Last thought: it is sobering that colorectal cancer is the third most common cancer in both men and women in the United States and the second most common cause of cancer-related death. African Americans have the highest incidence of colorectal cancer, >20% higher than in whites, and an even larger difference in mortality - they are more often diagnosed at an earlier age and with more advanced disease.

--課程已於 2020 年 6 月更新--

在本課程中，將採用一種非常有條理的、一步一步的方法來建立您所需要的所有理論，以瞭解支援向量機是如何真正運作的。

講師將使用邏輯迴歸( Logistic Regression )作為起點，這是你作為一名機器學習的學生學到的第一件事情。 因此，如果你想理解這門課程，只需要對邏輯迴歸(有一個好的直覺，並通過擴充套件，對直線、平面和超平面的幾何學有一個好的理解。

從這 9 小時的課程，你會學到

✅ 將支援向量機( SVMs )應用於實際應用程式: 影象辨識、垃圾郵件檢測、醫療診斷和迴歸分析( regression analysis )

✅ 從頭開始(基本幾何)理解支援向量機背後的理論

✅ 利用拉格朗日對偶(Lagrangian Duality)推導核心支援向量機

✅ 理解二次規劃( Quadratic Programming )是如何應用到支援向量機

✅ 支援向量迴歸

✅ Polynomial Kernel,，Gaussian Kernel，和 Sigmoid Kernel

✅ 基於支援向量機建立自己的 RBF 網路和其它神經網路

咖啡豆大腸

閱讀X光片是個學問，但有些狀況十分明顯，就算非醫護人員也可發現事有蹺蹊。「咖啡豆徵象」（coffee bean sign）就是一例，在X光片上出現一個不合比例地大的大腸，就像放大了的咖啡豆或腰豆一樣。這徵狀源於大腸在兩處地方像扭氣球般打結起來，令中間部分充氣漲大，在X光片上形成特別的形狀。

乙狀結腸扭轉（Sigmoid volvulus）患者多數為老人家，因爲扭轉會導致大腸阻塞（intestinal obstruction），所以病人會出現嘔吐、腹脹、便秘等徵狀。像氣球般大的大腸頂著腹部，相必一定很辛苦呢。

不過，結腸扭轉並非大腸阻塞的最常見成因，位於腸臟的腫瘤才是。雖然近年來透過大便隱血作大腸癌篩查愈來愈普及，但仍有患者到出現如大腸阻塞、貧血等徵狀而求醫才知道自己罹患癌症，或會因此而錯失及早治療的機會。政府最近降低了大腸癌篩查的合資格年齡，大家一定要（叫家人）參與啊！
