The following are questions from you, faithful AMA Manual of Style users, seeking clarification of AMA style guidelines or guidance on topics not covered in the current edition.
Q:
I think I know the answer to this but want to be sure. Do
you italicize “ad libitum” in “Animals were provided ad
libitum access to standard chow”?
A: The manual (22.5.4: Specific
Uses of Fonts, Typography) says this about italics:
[Use italics]
for some non-English words and phrases that are not shown among English terms
in the current edition of Merriam-Webster’s Collegiate Dictionary or in
accepted medical dictionaries. Italics are not used if words or phrases are
considered to have become part of the English language, eg, café au lait, in
vivo, in vitro, en bloc.
Merriam-Webster’s online
dictionary lists “ad libitum,” so there is no need to italicize it.
Interestingly, the example is “rats fed ad libitum.”
Q: I am wondering: How does one cite a clinical trial as a reference?
Do we treat them like a PI, or like a website? Do we include the identifier?
A: It would look most like a website
and yes, inclusion of the identifier is recommended:
1. Evaluation of phage therapy for the
treatment of Escherichia coli and Pseudomonas aeruginosa wound
infections in burned patients (PHAGOBURN). ClinicalTrials.gov identifier:
NCT02116010. https://www.clinicaltrials.gov/ct2/show/NCT02116010. Updated July
23, 2015. Accessed October 13, 2018.
Q: Hi, Should there be a comma between a last name and “Jr”
in a byline?
For example: Krzysztof Goniewicz, PhD; Frederick M.
Burkle, Jr, PhD
A: No, AMA style does not include a
comma before Jr or Sr, or before III, IV, etc.
See the policy and examples in chapter 8.2.1,
Punctuation, Comma.
Q: Does the manual have any position on whether “24/7” or
“24-7” are acceptable in formal prose, with the meaning “at all
times”? Thanks!
A: As far as formatting, it’s not in the current AMA manual, but the Chicago Manual of Style and AP stylebook
both use “24/7.”
Merriam-Webster’s
dictionary lists “24-7” as the primary entry, with “24/7” as a variant.
The JAMA Network journals have
generally preferred “24/7” considering that the slash serves to indicate “per”
(24 hours per 7 days). Numbers joined with a hyphen (24-7) could be confused
for a range or expression of variability, although the context of the passage
should alleviate that.
As to “24/7” being acceptable in
formal prose, it’s clearer to say “all the time” or something less jargony:
The
hospital has stroke expertise available 24/7.
Rewrite: The hospital has stroke
expertise always available.
Rewrite: The hospital has stroke
expertise available around-the-clock.
Q: I know you aren’t supposed to
refer to patients by their diseases, eg, “asthmatics.” How does that
apply to the following sentence:
Of the 196 patients, 20.4% (40)
were made comfort-focused care, and 79.6% (156) remained full codes.
What is the
alternative for “full code”?
A: Stylebook committee member Phil Fontanarosa, MD, MBA, replied:
With advance
directives, patients can choose to have any or none of these procedures and
also can opt for “comfort care,” which usually involves pain control,
perhaps some sedation, and other comfort measures.
For the
sentence, you could revise as something like the following: “Of the
196 patients, 20.4% (40) decided to have comfort-focused care, and 79.6%
(156) opted to receive full resuscitation efforts.”
Q: Hi, I have 2 questions about
authors’ initials:
1. If the journal typically
uses periods after middle initials in the byline and the author has 2 middle
initials, should there be a space between them?
2. If the journal uses first and
last author initials in the Disclosures section, should there be periods and
spaces between them?
A: The answer to both questions is yes.
Here’s an example from the 11th edition (forthcoming later this year) re the
second question:
Author Affiliations: Department of Psychiatry, Li Ka Shing Faculty of Medicine, The
University of Hong Kong, Hong Kong (S. K. W. Chan, S. W. Y. Chan, Hui, Chang,
Chen); The State Key Laboratory of Brain and Cognitive Sciences, The University
of Hong Kong, Hong Kong (S. W. K. Chan, Chang, Chen); School of Public Health,
