Signal recognition particle (SRP) receptor, also called docking protein, is a dimer composed of 2 different subunits that are associated exclusively with the rough ER in mammalian cells. Its main function is to identify the SRP units. SRP (signal recognition particle) is a molecule that helps the ribosome-mRNA-polypeptide complexes to settle down on the membrane of the endoplasmic reticulum.

This is a case of late post-renal azotemia, as you can tell by the BUN/Cr ratio that is <15 and the 3 day history of pain. They also tell you that the hydronephrosis and lymphadenopathy are compressing the ureters so it makes sense that you would want to stent the ureters. The others are all in the wrong location: Foley catheter (penis), suprapubic tube (bladder), stent in renal arteries (self explanatory).

Pretty sure this is a case of Legionella. The fact that it didn't show up on culture but a "highly specialized" medium (in hindsight buffered charcoal yeast) yielded gram-negative rods put Legionella on my radar. The headache and dry cough also line up with it but the macrolides threw me off since I thought they were treated with fluoroquinolone. But the sketchy video for macrolides includes Legionella as a target so it worked out.

Plasmodium vivax/ovale have dormant stages where their hypnozoites can stay latent in hepatocytes and trigger malaria well after the initial infection. The only malarial drug that covers against this is primaquine. The answer choice is just worded funny - "exoerythrocytic malarial tissue stages" basically is the stage where they are in the liver/not in RBC, and chloroquine won't work for those.

"Finger-shaped" lesions is suggestive of a papilloma and the findings being on the vocal cords and epiglottis make this a laryngeal papilloma. Most common cause of laryngeal papillomas is HPV 6 and 11, per sketchy.

Something key to note is that it's called "THROMB-oxane" for a reason.

"Named after its role in thrombosis, TxA2 has prothrombotic properties, as it stimulates the activation of platelets and platelet aggregation. TxA2 is also a known vasoconstrictor and gets activated during times of tissue injury and inflammation. While the prostaglandin counterbalances its thrombotic and vasoconstrictor properties prostacyclin (PGI2), there are various physiological and pathological situations where this balanced becomes dysregulated. Increased activity of TxA2 may play a role in the pathogenesis of myocardial infarction, stroke, atherosclerosis, and bronchial asthma. Increased action of TxA2 also has implications in pulmonary hypertension, kidney injury, hepatic injury, allergies, angiogenesis, and metastasis of cancer cells."

I also had no idea what the diagnosis was and purely went off elimination: Can't be fatty acid oxidation bc of the ketonemia, which you wouldn't be able to produce if that was the defect. Glycogen breakdown/synthesis are related to glycogen storage diseases, which the presentation didn't line up well with. Also I was thinking of a pathway that would incorporate glycerol, fructose and galactose which seemed more in line with gluconeogenesis/glycolysis. Between the last two, I went with faulty gluconeogenesis bc that would elad to his hypoglycemia. I don't know how legit or applicable that is to other questions, but thought I'd at least share in case anyone finds it helpful.

The way I think of motivational interviewing is that the goal is you want the patient to convince themself. So the goal is to get THEM to tell YOU the arguments for why they should quit.

The patient knows that smoking is bad for them. They have weighed out pros and cons in their mind and they're stuck at "I'm still going to smoke." Smoking HAS PROs: It feels great, reduces anxiety, they're used to it, and if they were to quit they'd go through awful withdrawals. But the patient also knows that there are cons. It's going to kill them.

If you start listing all the reasons why it's bad for them that they already know, they'll want to balance out the argument for why they still smoke. You're saying the cons, so they feel the need to justify the pros. BUT if you ask them what smoking is doing for them that's good, they'll feel the need to justify the cons: "Well it helps with my anxiety, but I know that's not a good enough reason to keep smoking." You can also have them argue your side by talking in the extreme in the opposite way: "So you'd NEVER see yourself quitting?" "Oh no of course I want to quit eventually!"

Here's a good list of questions to ask in each stage: https://www.aafp.org/afp/2018/1215/hi-res/afp20181215p719-t2.gif

Main groups There are two main groups of cyclins:

β€’ G1/S cyclins – essential for the control of the cell cycle at the G1/S transition;
β€’ Cyclin A / CDK2 – active in S phase.
β€’ Cyclin D / CDK4, Cyclin D / CDK6, and Cyclin E / CDK2 – regulates transition from G1 to S phase.
β€’ G2/M cyclins – essential for the control of the cell cycle at the G2/M transition (mitosis). G2/M cyclins accumulate steadily during G2 and are abruptly destroyed as cells exit from mitosis (at the end of the M-phase).
β€’ Cyclin B / CDK1 – regulates progression from G2 to M phase.

"The flexor group of muscles is involved in pronation of the forearm and flexion of the wrist and fingers, while the extensor group of muscles is involved in the supination of the forearm and extension of the wrist and fingers."

From Amboss

Weakness of extension (Radial n) and pronation (Median n).

C6 damage would give you MC signs. C8 would give you ulnar signs. C7 goes to Median and Radial.

Hypocalcemia can present with muscular twitching and spams, might cause tetany, and in severe cases lead to seizures like happened in this patient.

This question can be confusing mainly because whenever u think of seizure or neurologic manifestation, you think of Sodium, but the key here is the 1 MONTH history of episodes of pins-and-needles with involuntary contraction of muscles. Also you can rule out Potassium, because although it can cause muscle cramps, spasms and weakness, it leads to cardiac abnormalities (arrhythmias).

I do not know if that was 100% correct but I agree with eliminating answers contain sensitivity or specificity because that is not a screening test and eliminating other studies as they did not mention anything about other studies, here is what I think we here have 2 numerical values 9 interval variables ) so we will use statistical test person correlation as it needs 2 interval variable and graph done by the test will give us idea about strength of the correlation. temopral relationship ( temporality )means : tests whether the outcome occurs after the effect (e.g., surgical site infection occurs after incision of the skin) dose response relationship : tests whether greater exposure usually leads to a higher occurrence of the outcome (e.g., the greater the exposure to ionizing radiation, the higher the risk of malignancy) . and both can be applicable here . source : amboss.

Hormones/drugs use signaling pathways to exert their effect on tissues.

In particular steroid hormones, fat soluble vitamins, and thyroid hormones (T3/T4) utilize an intracellular receptor signaling pathway which translocates to the nucleus and binds to DNA, up regulating or down regulating transcription of certain genes.

PET CAT on TV is the mnemonic that is given in FA.

Vitamin D is given in FA, but Vitamin A isn't mentioned in Uworld: fat soluble (A,D,E,K) vitamins are given.

Hope this helps!

On the pedigree, it clearly shows maternal inheritance, this is what distinguishes it from literally all other options. Mitochondrial myopathies show MATERNAL inheritance (on a pedigree chart the circle aka female is affected and only the female can pass it on to her kids, an affected male can NEVER pass it on to his kids), why? Because sperm cells lose their mitochondrial DNA before fertilization, so in all of your cells, your mitochondrial DNA is from mom. Now, when mom passes down her mitochondrial DNA, she can be passing down her mutated mitochondrial DNA and a portion of normal mitochondrial DNA this mixture is called heteroplasy, it means that a person with a mitchondrial myopathy can show variability in the clinical symptoms they present with.

This means, they can be more severe in their presentation or less severe. In the vignette it states that mom has 50% mutated mitochondrial DNA versus her offspring who have 100% mutated mitochondrial DNA. Her kids presented more severely, than she did, aka variable clinical presentation in a mitchondrial myopathy = heteroplasmy.

Contrast this with variable expressivity, which occur in autosomal dominant disorders, not mitochondrial myopathies.

Specifically this process is called disuse atrophy. It is a type of atrophy, a cellular adaptation occurring in response to stress. This cellular adaptation causes protein degradation via ubiquitin proteasome pathway. This is why his calf is smaller than his other normal one.

Acetaminophen normally is degraded by hepatic glucoronidation, but in chronic acetaminophen users, this pathway becomes "saturated". So the body uses the Cyt. P-450 enzyme system to convert it to N-acetyl-benzoquinonemine (NAPQI), which causes free radical damage. The question asks, which of the following effects of alcohol most likely contributed to this patients condition?

A,B,C,D are all anti free radical generation, and would not contribute to this patients condition. This leaves E, Alcohol is an inducer (basically ramps up CYT p450) of the P450 enzyme system which causes elevated levels of NAPQI.

This child has minimal change disease, the most common cause of nephrotic syndrome in children. It is often primary (idiopathic) and may be triggered by a recent infection, immunization, or other immune stimulus.

Thymic output of T cell repertoire during the growing phases is vital, but it becomes unnecessary for repertoire maintenance during adulthood. This happens because the T cell regeneration in adulthood is almost entirely derived from homeostatic proliferation of the EXISTING T cell pool, which is sufficient to maintain a large compartment of naive CD4 T cells. Thymic T cell generation can add new naive T cells and enrich diversity, while homeostatic T cell proliferation can sustain the richness of the TCR repertoire already created. This means that the Thymic lymphocytes produced before thymectomy are long-lived naive T cells, which are maintained stable in quantity thanks to Homeostatic proliferation in adulthood.

summary of pathogenesis

hemochromatosis = mutation on HFE gene(codes for an iron sensor)

mutation > defect in sensor > body assumes low iron.

2 organs now make attempt to increase body iron.

1, small intestine, increases expression of DMT in lumen.

2, liver decreases hepcidin, so that ferroportin can be expressed on the basolateral surface of enterocyte.

why ? so that the iron absorbed via dmt can be taken to the blood via feroportin.

Wedged hepatic venous pressure (WHVP) is measured by inflating a balloon at the catheter tip, thus occluding a hepatic vein branch. Measurement of the WHVP provides a close approximation of portal pressure.Β  The HVPG is defined as the difference in pressure between the portal vein and the inferior vena cava. Thus, the HVPG is equal to the WHVP value minus the FHVP value (ie, HVPG = WHVP - FHVP). The normal HVPG is 3-6 mm Hg. 5mmHg Here-->NO cirrhosis

I knew it had to be X-linked because it said that it was fatal to males who have it in utero, but I had a hard time deciding between dominant and recessive. Ultimately it has to be X-linked dominant because the affected mother in the second generation gave birth to unaffected sons (which can't happen in X-linked recessive). That means the mother in question is heterozygous and her daughters will have a 50% chance of inheriting the disease while her sons have to be unaffected if they live, as previous posters mentioned. I didn't figure this out until way after the test...this one was a doozy. Still not sure that it's XLD because how come nobody in the first gen has it? Guessing it was a spontaneous mutation?

could it also be possible to get this by remembering the different ventricle spaces as well. i honestly didnt remember what hydrocephalus this could be. But i remembered the mnemontic LIT AFF to SAD.(Lateral ventrical, intraventricular foramina of monroe, third ventrical, cerebral aqueduct, fourth ventricle, foramina of lushka, subarachannoid, arachanoid granulations, dural venous sinus). And i recognized they were talking about a widing of subarachanoid space and thought what was the closest thing to interefere and thats how i got to B.

Also i just want to say looking at the answers i know its a communicating hydrocephalus, i just wanna know if this was also a good way to extract the answer or if i just winded up getting lucky a little LOL.

I just wanted to add a note here. I was confused on why you would give the patient leucovorin with the MTX. The reason is that it "rescues" the normal cells from damage/death, and allows the MTX to attack only the cancer cells.

Also another connection we may need to know is that if leucovorin with 5-FU it makes it more effective/toxic at killing cancer cells!

SIMPLE. 3 steps.

  1. we know this girl has cystic fibrosis .

  2. but testing shows only 1 allele is mutated.

  3. since she has CF, the other allele CANNOT be normal , and the only explanation to her having CF is the panel didnt detect it.

i have never herd acetylsalicylic being prescribed for gout, and i practiced for a couple of years.

so think simple, choose probenicid since its a fairly known drug in the gout world, and enjoy your 250 on step 1

Patients with irritable bowel syndrome (IBS) who have significant gastrointestinal bloating symptoms can be treated with antispasmodic medications (eg, dicycloverine) that block gastrointestinal muscarinic receptors.Β  Those with constipation-predominant IBS are sometimes treated with lubiprostone, a chloride channel activator, to increase intestinal fluid secretion.Β  IBS is usually marked by periods of diarrhea and/or constipation and abdominal bloating; early satiety and vomiting of undigested food would be atypical.
