Essential Productivity Apps for any student:

  1. Caffeine-  Prevents your screen from going into sleep mode. Great if you’re writing notes on an article and the screen keeps dimming, whilst you hope that if you stare long enough, the phrase “homologous ways to a view of hegemony” will start to make sense.
  2. Flux- If you find that you can’t sleep for ages after studying late at night, then this app is a total game changer. It basically turns the light on the screen red, because science people say that blue light keeps you awake and red light doesn’t. (*Full Disclosure* I’m not a scientist)
  3. Focusbar- The annoying voice of your mother nagging you to finish your homework…in app form. You can set the annoying level (I have it set on “wildly annoying”) and a bar will appear in the corner every few seconds to remind you that you’re supposed to be doing something else besides looking at cat photos. 
  4. Microsoft Office- self explanatory, so I’ve linked to an article about life hacks for Microsoft Office instead. Because I’m just that awesome. 
  5. Nag- Does your 5 minute study break keep turning into an hour on Youtube? Then you need Nag in your life. It’s basically an alarm/timer. But an extremely loud and annoying alarm/timer that’s very difficult to ignore. The bells genuinely sound more judgemental the longer you ignore it.  
  6. Self Control-  Also known as Cold Turkey for Microsoft users. If you absolutely cannot be trusted with an internet connection, then you need Self Control in your life. You add a list of websites to the “blacklist”and then set how long you want the app to work for, and for that duration of time you wont be able to access those website. Seriously, not even rebooting your computer or uninstalling the app will let you access the blacklist until your time is up. Tough love at its finest.
  7. Zotero-  The new love of my life. Zotero allows you to manage all your citations and sources in one easy place. It’s an absolute life saver- no joke. There’s an in-word add in, so it will write your bibliography and citations for you in any format you want. There’s a chrome/firefox add in and a mobile app, so you don’t even have to type the citation into Zotero. Just press the button it does all the hard work for you. It even updates itself online, so you can still access your bibliography if your computer crashes. I <3 Zotero 5eva.

ANTIBIOTICS CHEAT SHEET :)

Also, REMEMBER!!!!

* Sulfonamides compete for albumin with:

  • Bilirrubin: given in 2°,3°T, high risk or indirect hyperBb and kernicterus in premies
  • Warfarin: increases toxicity: bleeding

Beta-lactamase (penicinillase) Suceptible:

  • Natural Penicillins (G, V, F, K)
  • Aminopenicillins (Amoxicillin, Ampicillin)
  • Antipseudomonal Penicillins (Ticarcillin, Piperacillin)

Beta-lactamase (penicinillase) Resistant:

  • Oxacillin, Nafcillin, Dicloxacillin
  • 3°G, 4°G Cephalosporins
  • Carbapenems 
  • Monobactams
  • Beta-lactamase inhibitors

* Penicillins enhanced with:

  • Clavulanic acid & Sulbactam (both are suicide inhibitors, they inhibit beta-lactamase)
  • Aminoglycosides (against enterococcus and psedomonas)

Aminoglycosides enhanced with Aztreonam

* Penicillins: renal clearance EXCEPT Oxacillin & Nafcillin (bile)

* Cephalosporines: renal clearance EXCEPT Cefoperazone & Cefrtriaxone (bile)

* Both inhibited by Probenecid during tubular secretion.

* 2°G Cephalosporines: none cross BBB except Cefuroxime

* 3°G Cephalosporines: all cross BBB except Cefoperazone bc is highly highly lipid soluble, so is protein bound in plasma, therefore it doesn’t cross BBB.

* Cephalosporines are ”LAME" bc they  do not cover this organisms 

  • L  isteria monocytogenes
  • A  typicals (Mycoplasma, Chlamydia)
  • RSA (except Ceftaroline, 5°G)
  •  nterococci

image

* Disulfiram-like effect: Cefotetan Cefoperazone (mnemonic)

* Cefoperanzone: all the exceptions!!!

  • All 3°G cephalosporins cross the BBB except Cefoperazone.
  • All cephalosporins are renal cleared, except Cefoperazone.
  • Disulfiram-like effect

* Against Pseudomonas:

  • 3°G Cef taz idime (taz taz taz taz)
  • 4°G Cefepime, Cefpirome (not available in the USA)
  • Antipseudomonal penicillins
  • Aminoglycosides (synergy with beta-lactams)
  • Aztreonam (pseudomonal sepsis)

* Covers MRSA: Ceftaroline (rhymes w/ Caroline, Caroline the 5°G Ceph), Vancomycin, Daptomycin, Linezolid, Tigecycline.

Covers VRSA: Linezolid, Dalfopristin/Quinupristin

* Aminoglycosides: decrease release of ACh in synapse and act as a Neuromuscular blocker, this is why it enhances effects of muscle relaxants.

* DEMECLOCYCLINE: tetracycline that’s not used as an AB, it is used as tx of SIADH to cause Nephrogenic Diabetes Insipidus (inhibits the V2 receptor in collecting ducts)

* Phototoxicity: Q ue S T  ion?

  • uinolones
  • Sulfonamides
  • T etracyclines

image

* p450 inhibitors: Cloramphenicol, Macrolides (except Azithromycin), Sulfonamides

* Macrolides SE: Motilin stimulation, QT prolongation, reversible deafness, eosinophilia, cholestatic hepatitis

Bactericidal: beta-lactams (penicillins, cephalosporins, monobactams, carbapenems), aminoglycosides, fluorquinolones, metronidazole.

* Baceriostatic: tetracyclins, streptogramins, chloramphenicol, lincosamides, oxazolidonones, macrolides, sulfonamides, DHFR inhibitors.

Pseudomembranous colitis: Ampicillin, Amoxicillin, Clindamycin, Lincomycin.

QT prolongation: macrolides, sometimes fluoroquinolones
