The Winters formula and the thumb rule
The Winters formula
is used to assess the appropriateness of the pCO2 response to
metabolic acidosis (and thus determine whether a concomitant
respiratory acid base disturbance exists). Here’s an interesting post from the archives of the Renal Fellow Network.

Rivaroxaban versus warfarin and recurrent VTE
Methods
In this propensity-matched cohort study, we linked nationwide Danish health registries to identify all patients with a first hospital diagnosis of unprovoked VTE who were new users of rivaroxaban or warfarin. Excluded patients included those who had not been residents in Denmark for at least 1 year before VTE diagnosis, patients with outpatient VTE diagnosis only, patients with other indications for oral anticoagulation treatment, patients with previous experience of oral anticoagulation, patients who did not have a prescription for rivaroxaban or warfarin within 7 days of VTE, and patients who redeemed prescriptions for both rivaroxaban and warfarin, or other oral anticoagulants. Primary effectiveness outcome was recurrent VTE and primary safety outcome was major bleeding. We used propensity matching and Cox regression to compare rates of the outcomes with rivaroxaban versus standard treatment.
Results
From Dec 9, 2011, to Feb 28, 2016, we identified 29 963 patients with incident VTE. After exclusion, we identified 1734 propensity-matched patients given rivaroxaban (1751 before propensity matching) and 2945 propensity-matched patients given warfarin. The rate of recurrent VTE at 6 months' follow-up was 9·9 incidents per 100 person-years with rivaroxaban versus 13·1 incidents per 100 person-years with warfarin, yielding a hazard ratio (HR) of 0·74 (95% CI 0·56–0·96). The rate of major bleeding was 2·4 per 100 person-years at 6 months in rivaroxaban users versus 2·0 in warfarin users (HR 1·19, 95% CI 0·66–2·13).
Interpretation
In this clinical practice setting, rivaroxaban in patients with unprovoked VTE was associated with reduced risk of recurrent VTE compared with standard treatment, without compromising safety.
A related editorial
pointed out the potential confounding effects of return visits for
INR monitoring being interpreted as recurrent events.

Cardiac cachexia is associated with sympathetic nerve activity in skeletal muscle
Introduction: Cardiac cachexia is associated with poor prognosis in patients with heart failure (HF). Sympathetic overactivation might be implicated in the development of muscle wasting, considering the recent data that carvedilol significantly reversed body weight (BW) loss in HF patients…
Methods: We prospectively evaluated changes in BW in 108 non-edematous HFrEF patients in whom muscle sympathetic nerve activity (MSNA) was measured...
Results... One-year combined event rate was significantly higher in BW loss group...MSNA...was significantly higher in BW loss group than in non-BW loss group. Importantly, MSNA burst incidence had a moderate predictability for significant BW loss by receiver-operating characteristic analysis (area under the curve=0.794).
Conclusion: Sympathetic overactivation determined by MSNA could predict significant BW loss in HFrEF patients.

Sleep and cardiovascular disease
Abstract:
Purpose of review: Sleep plays many roles in maintenance of cardiovascular health. This review summarizes the literature across several areas of sleep and sleep disorders in relation to cardiometabolic disease risk factors.
Recent findings: Insufficient sleep duration is prevalent in the population and is associated with weight gain and obesity, inflammation, cardiovascular disease, diabetes, and mortality. Insomnia is also highly present and represents an important risk factor for cardiovascular disease, especially when accompanied by short sleep duration. Sleep apnea is a well-characterized risk factor for cardiometabolic disease and cardiovascular mortality. Other issues are relevant as well. For example, sleep disorders in pediatric populations may convey cardiovascular risks. Also, sleep may play an important role in cardiovascular health disparities.
Summary: Sleep and sleep disorders are implicated in cardiometabolic disease risk. This review addresses these and other issues, concluding with recommendations for research and clinical practice.

Clinical pharmacists as ID docs in the ER?
Introduction
Pneumonia impacts over four million people annually and is the leading cause of infectious disease-related hospitalization and mortality in the United States. Appropriate empiric antimicrobial therapy decreases hospital length of stay and improves mortality. The objective of our study was to test the hypothesis that the presence of an emergency medicine (EM) clinical pharmacist improves the timing and appropriateness of empiric antimicrobial therapy for community-acquired pneumonia (CAP) and healthcare-associated pneumonia (HCAP).
Methods
This was a retrospective observational cohort study of all emergency department (ED) patients presenting to a Midwest 60,000-visit academic ED from July 1, 2008, to March 1, 2016, who presented to the ED with pneumonia and received antimicrobial therapy. The treatment group consisted of patients who presented during the hours an EM pharmacist was present in the ED (Monday-Friday, 0900–1800). The control group included patients presenting during the hours when an EM clinical pharmacist was not physically present in the ED (Monday–Friday, 1800–0900, Saturday/Sunday 0000–2400 day). We defined appropriate empiric antimicrobial therapy using the Infectious Diseases Society of America consensus guidelines on the management of CAP, and management of HCAP.
Results
A total of 406 patients were included in the final analysis (103 treatment patients and 303 control patients). During the hours the EM pharmacist was present, patients were significantly more likely to receive appropriate empiric antimicrobial therapy (58.3% vs. 38.3%; p less than 0.001). Regardless of pneumonia type, patients seen while an EM pharmacist was present were significantly more likely to receive appropriate antimicrobial therapy (CAP, 77.7% vs. 52.9% p=0.008, HCAP, 47.7% vs. 28.8%, p=0.005). There were no significant differences in clinical outcomes.
Conclusion
The presence of an EM clinical pharmacist significantly increases the likelihood of appropriate empiric antimicrobial therapy for patients presenting to the ED with pneumonia.
The physical
presence of clinical pharmacists in the ER was associated with more
appropriate antibiotics according to this study, but we don’t know
the nature of their involvement in treatment decisions. The HCAP
designation used in the report is now considered obsolete and no
longer recognized in the guidelines although it was appropriate for
the time frame of the study. The major error in the control group
was in categorization of patients as either CAP or HCAP. The strong
implication is that pharmacists were better at diagnosing the type of
pneumonia than the docs. There is something very wrong here.

Are we practicing EBM in the treatment of ARDS?
Far from it, it seems. Just over a quarter of patients with ARDS in the study
got low tidal volume ventilation. Moreover, only about half the
patients meeting ARDS criteria were acknowledged as such.

Exercise, Parkinson disease and dementia
Parkinson disease is a slowly progressive neurodegenerative condition; after many years, dementia or medication-refractory motor symptoms may develop.
A myriad of animal studies document a direct, favorable effect of aerobic-type exercise on the brain; this includes liberation of neurotrophic hormones and enhancement of a variety of neuroplasticity mechanisms. Exercise tends to protect animals from neurotoxins that induce parkinsonism.
Long-term exercise and fitness in healthy humans is associated with greater volumes of cerebral cortex and hippocampus and less age-related white matter pathology.
Midlife exercise is associated with a significantly reduced later risk of Parkinson disease.
Conclusion from this evidence: Regular aerobic-type exercise tending to lead to fitness is the single strategy with compelling evidence for slowing Parkinson disease progression. All patients with Parkinson disease should be encouraged to engage in regular such exercise.

Dealing with drug allergy
Drug Allergy: An Updated Practice Parameter is
an official document promulgated by a collaboration of three
professional societies. Although it is a bit dated it is the latest
such edition written by the collaboration. Moreover, for penicillin
allergy an update
was published in Mayo Clinic Proceedings only months ago. The Mayo
update generally follows the recommendations of this document. Below
are some key points.
The overall classification of drug induced disease encompasses all
types of adverse reactions, not just allergic reactions.
From the document:
ADRs are broadly categorized into predictable (type A) and unpredictable (type B) reactions. Predictable reactions are usually dose dependent, are related to the known pharmacologic actions of the drug…
Unpredictable reactions are generally dose independent, are unrelated to the pharmacologic actions of the drug, and occur only in susceptible individuals. Unpredictable reactions are subdivided into drug intolerance, drug idiosyncrasy, drug allergy, and pseudoallergic reactions.
Allergic reactions are defined as immunologic reactions. Although
the Gell-Coombs classification remains the framework for thinking
about allergic reactions, the current classification has been
extended beyond that.
Categories outside the C-G
classification include
these below. Form the paper:
Hypersensitivity vasculitis Cutaneous or visceral vasculitis Hydralazine, penicillamine, propylthiouracil
DRESS Cutaneous, fever, eosinophilia, hepatic dysfunction, lymphadenopathy Anticonvulsants, sulfonamides, minocycline, allopurinol
Pulmonary drug hypersensitivity Pneumonitis, fibrosis Nitrofurantoin, bleomycin, methotrexate
Systemic drug-induced lupus erythematosus Arthralgias, myalgias, fever, malaise Hydralazine, procainamide, isoniazid
Cutaneous drug-induced lupus erythematosus Erythematous/scaly plaques in photodistribution Hydrochlorothiazide, calcium channel blockers, ACE inhibitors
Drug-induced granulomatous disease Churg-Strauss syndrome, Wegener's granulomatosis Propylthiouracil, leukotriene modifiers
Immunologic hepatitis Hepatitis, cholestatic jaundice Para-aminosalicylic acid, sulfonamides, phenothiazines
Blistering disorders Erythema multiforme, SJS, TEN Sulfonamides, cephalosporins, imidazole anticonvulsants, NSAIDs
Serum sickness–like reactions Erythema multiforme, arthralgias Cefaclor, cefprozil
Immunologic nephropathy Interstitial nephritis, membranous glomerulonephritis Penicillin, sulfonamides, gold, penicillamine, allopurinol
It should be mentioned that some of the categories listed above are
poorly understood and may not represent purely immunologic
mechanisms.
What is “desensitization?”
More from the paper:
What has often been referred to as drug desensitization is more appropriately described in this parameter as a temporary induction of drug tolerance. Drug tolerance is defined as a state in which a patient with a drug allergy will tolerate a drug without an adverse reaction. Drug tolerance does not indicate either a permanent state of tolerance or that the mechanism involved was immunologic tolerance. Induction of drug tolerance procedures modify a patient's response to a drug to temporarily allow treatment with it safely. They are indicated only in situations where an alternate non–cross-reacting medication cannot be used. Induction of drug tolerance can involve IgE immune mechanisms, non-IgE immune mechanisms, pharmacologic mechanisms, and undefined mechanisms ( Table 2 ). All procedures to induce drug tolerance involve administration of incremental doses of the drug. Through various mechanisms, these procedures induce a temporary state of tolerance to the drug, which is maintained only as long as the patient continues to take the specific drug.
Remember that this technique is
recommend only when there is no reasonable alternative, and it
doesn’t induce permanent tolerance.
There is also the idea of graded challenge, which is different from
tolerance induction (desensitization). Graded challenge is
essentially the administration of a test dose.
Remember this, too, from the paper:
Graded challenge (or induction of drug tolerance) should almost never be performed if the reaction history is consistent with a severe non–IgE-mediated reaction, such as SJS, TEN, interstitial nephritis, hepatitis, or hemolytic anemia.
The recommendations for dealing with beta lactam type I allergy
are complex
If the allergic history is that
of an anaphylactoid reaction there is almost no avoiding the use of
special techniques such as skin testing or tolerance induction, were
one to strictly follow the document recommendations.
Clinical rules cannot assure safe administration of an antibiotic.
Consider assessment of side chain similarity for the assessment of
safety of cephalosporin administration, for example. Although side
chain assessment can be of help in the assessment of risk, in the
document there is no recommendation for using it as an assurance of
safety. On the other hand, in a couple of cases it can be used to
mandate avoidance (such as the use of aztreonam in a patient with an
anaphylactoid reaction to ceftazidime).
The application of the special techniques of skin testing, test
dosing and tolerance induction is complex and has many contingencies
noted in the document and therefore requires expertise.
Practical aspects for the clinician in dealing with type 1 beta
lactam allergy
Despite
the complexities noted above one can be informed by data on absolute
risk. For example, according to the Mayo paper,
cross-reactivity between PCN and carbapenems
is likely less than 1%, with similar risk for aztreonam. What should
one do, for example, when confronted with a patient in septic shock
with concern for pseudomonas and ESBL producing bacteria?
Considering a mortality increase of 5-10% per hour of non coverage,
can you get an allergist on site and skin testing done in time or
does the risk of delay exceed a less than 1% chance of a reaction
from a carbapenem?

New alcoholic liver disease guidelines from the American College of Gastroenterology
The document is
worth reading in its entirety, but there were a few points I found
particularly noteworthy:
Patients who are
obese should not consume any ethanol at all!
Definitions, from
the paper:
Alcoholic fatty liver disease is diagnosed in a patient with AUD with hepatic steatosis on ultrasound and/or elevation in liver enzymes (aspartate aminotransferase (AST) greater than alanine aminotransferase (ALT)), serum bilirubin less than 3 mg/dL, and the absence of other causes of liver disease.
Clinical diagnosis of AH is determined in a patient with rapid development or worsening of jaundice and liver-related complications, with serum total bilirubin greater than 3 mg/dL; ALT and AST elevated greater than 1.5 times the upper limit of normal but less than 400 U/L with the AST/ALT ratio greater than 1.5; documentation of persistent heavy alcohol use until 8 weeks before onset of symptoms; and exclusion of other liver diseases
Baclofen to help
patients stop drinking has a conditional recommendation:
In patients with ALD, baclofen is effective in preventing alcohol relapse (Conditional recommendation, low level of evidence).
Pentoxifylline is
no longer recommended for severe alcoholic hepatitis. Steroids
still are.
At 7 days into
steroid therapy the Lille score should be used to determine if the
steroids should be continued:
Response to treatment with corticosteroids should be determined at 7 days using the Lille score. Treatment should be discontinued among non-responders to therapy, defined as those with a Lille score greater than 0.45.
The guideline
authors acknowledge evidence that N-acetylcysteine infusion in
combination with steroids may be associated with improved outcomes in
AH. However, they do not feel the evidence is sufficiently strong to
justify a guideline recommendation.
Antibiotic
therapy is still recommended as part of the overall treatment regimen
for variceal bleeding:
Management of the acute variceal bleeding episode involves pharmacological therapy with available vasoactive agents (terlipressin or octreotide), antibiotics, and endoscopic therapy. Endoscopy should ideally be carried out at least 30 min after initiation of vasoactive therapy (54).
As for the optimal
timing of endoscopy, that last sentence is confusing to me.
Have a low
threshold for starting broad spectrum antibiotics in AH patients who
become critical.
Concerning the gram negative component of the
regimen, the guideline recommends merropenem or zosyn, acknowledging
that the clinician should pay attention to local sensitivity
patterns:
The choice of antibiotics depends on prevailing local antimicrobial resistance patterns. Piperacillin-tazobactam is generally the preferred drug used for sepsis, although vancomycin and meropenem may be considered in patients with penicillin hypersensitivity.
There’s much more.

Idiopathic paroxysmal AV block due to low baseline adenosine levels and heightened receptor sensitivity
Idiopathic paroxysmal AV block poses a true diagnostic challenge. Although it is true that the clinical presentation does not differ from that of another cardiogenic syncope, the diagnosis of this block requires the lack of a structural cardiac pathology that justifies the observed manifestations and an absence of electrocardiographic disorders prior to an episode. For diagnosis, it is useful the implantable loop recorder to substantiate AV block paroxysms and assess their clinical correlations.
The mechanism associated with idiopathic paroxysmal AV block is unknown. It has been postulated that patients with low basal adenosine levels exhibit hyperaffinity of the adenosine receptors of the AV node. No relevant data have been reported, so it´s necessary that more studies are needed to confirm this hypothesis.
The prognosis of idiopathic paroxysmal AV block is favorable, given the paroxysmal profile of the AV block and the low probability of degeneration into permanent forms of AV block. Permanent stimulation devices can be employed to prevent and avoid the recurrence of syncopal episodes in patients with idiopathic paroxysmal AV block.

Pitfalls in ICU management
This article in Today's Hospitalist,
drawn from recent talks at the UCSF hospitalist conference, has a lot
of pearls. Most of the admonitions are about avoiding knee jerk
care.
The real gem comes in her discussion of
the importance of de-escalation of IV fluids:
“Multiple studies have replicated that, even in sepsis,” Dr. Santhosh noted. “After initial resuscitation with early goal-directed therapy, you want a maintenance or stabilization phase and then de-escalation.” That could mean active diuresis in patients to attain a negative fluid balance once they’re off pressors.
And while it can be a challenge to find the maintenance fluids in your EHR to discontinue them…
That’s right. She said, in effect,
that the EHR interferes with the clinician’s ability to discontinue
potentially harmful IV fluids. The statement rings true and concerns
one of those key provisions of meaningful use: CPOE. Meaningful to
patients for sure if it interferes with their care with the potential
for harm.

Hypothyroidism and heart disease
Free full text
review.
From the review:
Hypothyroidism can result in decreased cardiac output, increased systemic vascular resistance, decreased arterial compliance, and atherosclerosis.
Impaired cardiac muscle relaxation, decreased heart rate, and decreased stroke volume contribute to heart failure in hypothyroidism.
Subclinical hypothyroidism is associated with ischemic heart disease and increased cardiovascular mortality.
Treatment of hypothyroidism may have a beneficial impact on several parameters of cardiac dysfunction, including subclinical hypothyroidism, especially in younger individuals.

Insulin autoimmune syndrome aka Hirata disease
It’s caused by
spontaneous development of insulin antibodies (no prior exposure to
insulin). If that’s the case why does it cause hypoglycemia and
not just hyperglycemia? From a review:
Although the precise mechanism for hypoglycemia in IAS is unknown, the most widely accepted hypothesis is a mismatch between blood glucose and free insulin concentration, secondary to the binding and release of secreted insulin by autoantibodies.7 Following a meal or oral glucose load, glucose concentration in the bloodstream rises, providing a stimulus for insulin secretion. Autoantibodies bind to these insulin molecules, rendering them unavailable to exert their effects. The resultant hyperglycemia not only promotes further insulin release, but may also explain the increased hemoglobin A1c often seen in IAS patients.6 As glucose concentration eventually falls, insulin secretion also subsides, and the total insulin level decreases. Insulin molecules spontaneously dissociate from the autoantibodies at this time, giving rise to a raised free insulin level inappropriate for the glucose concentration, evoking hypoglycemia.7 Insulin autoantibodies with a high binding capacity and a low affinity are more likely to bring about hypoglycemic symptoms.10 Medications containing a sulfhydryl group have been proposed to induce autoantibody formation by interacting with the disulfide bonds of the insulin molecule and augmenting its immunogenicity;11 however, the true underlying pathophysiology remains unclear at this time. Rarely, the co-existence of both insulin autoantibodies and insulin receptor autoantibodies within the same patient has been described.12

Physician burnout: a public health crisis
Burn out drivers for

Renin-angiotensin blockade in heart failure with preserved EF? Mixed results.
From a recent
review:
Studies with angiotensin‐converting enzyme inhibitors (ACE‐Is) and angiotensin receptor blockers (ARBs) in patients with heart failure with preserved ejection fraction (HFpEF) have yielded inconsistent results. To conduct a systematic review and meta‐analysis of all evidence for ACE‐I and ARBs in patients with HFpEF, we searched PubMed, Ovid SP, Embase, and Cochrane database to identify randomized trials and observational studies that compared ACE‐I or ARBs against placebo or standard therapy in HFpEF patients. Random‐effect models were used to pool the data, and I 2 testing was performed to assess the heterogeneity of the included studies. A total of 13 studies (treatment arm = 8676 and control arm = 8608) were analysed. Pooled analysis of randomized trials for ACE‐I and ARBs (n = 6) did not show any effect on all‐cause mortality [relative risk (RR) = 1.02, 95% confidence interval (CI) = 0.93–1.11, P = 0.68, I 2 = 0%], while results from observational studies showed a significant improvement (RR = 0.91, 95% CI = 0.87–0.95, P = 0.005, I 2 = 81.5%). In pooled analyses of all studies, ACE‐I showed a reduction of all‐cause mortality (RR = 0.91, 95% CI = 0.87–0.95, P = 0.01). There was no reduction in cardiovascular mortality seen, but in pooled analysis of randomized trials, there was a trend towards reduced HF hospitalization risk (RR = 0.91, 95% CI = 0.83–1.01, I 2 = 0%, P = 0.074). These data suggest that ACE‐I and ARBs may have a role in improving outcomes of patients with HFpEF, underscoring the need for future research with careful patient selection, and trial design and conduct.

Not challenging science is anti-science??
But I thought science
was inherently self-challenging. To Dr. John’s credit, though, he does make some good points about the thought police. They’re
everywhere in medicine.
Doctors in the US make too much money
---according to a
policy wonk at one progressive think tank. So, says he, we must apply pressure from all sides to break up the cartel and reduce doctors’ pay. The fact that patients generally like their doctors doesn’t help.

Inappropriate antibiotic prescribing for patients sent home from the ER
Results
Of 1579 ED antibiotic prescriptions in 2015, we reviewed a total of 159 (10.1%) prescription records. The most frequently prescribed antimicrobial classes included penicillins (22.6%), macrolides (20.8%), cephalosporins (17.6%), and fluoroquinolones (17.0%). The most common indications for antibiotics were bronchitis or upper respiratory tract infection (URTI) (35.1%), followed by skin and soft tissue infection (SSTI) (25.0%), both of which were the most common reason for unnecessary prescribing (28.9% of bronchitis/URTIs, 25.6% of SSTIs). Of the antimicrobial prescriptions reviewed, 39% met criteria for inappropriateness. Among 78 prescriptions with a consensus on appropriate indications, 13.8% had inappropriate dosing, duration, or expense.
Conclusion
Consistent with national outpatient prescribing, inappropriate antibiotic prescribing in the ED occurred in 39% of cases with the highest rates observed among patients with bronchitis, URTI, and SSTI. Antimicrobial stewardship programs may benefit by focusing on initiatives for these conditions among ED patients. Moreover, creation of local guideline pocketbooks for these and other conditions may serve to improve prescribing practices and meet the Core Elements of Outpatient Stewardship recommended by the Centers for Disease Control and Prevention.
