Given a context passage, generate a question from the passage such that its answer is shortest continous span from the passage.

[Q]: While Clostridium difficile epidemiology is well documented in many European countries, data are largely missing for South Eastern European region. Here we report the PCR ribotype distribution of 249 C.difficile isolates received for typing from six hospital settings from Croatia, Bosnia and Herzegovina, Republic of Macedonia and Serbia in time period from 2008 to 2015. Twenty-four PCR ribotypes were detected. The majority of strains from Bosnia and Herzegovina and Serbia belonged to PCR ribotype 027 (65.8%). Other three dominating PCR ribotypes were 176 (18 strains; Croatia), 001/072 (15 strains; all countries) and 014/020 (15 strains; all countries).
[A]: Which main ribotype of Clostridium difficile is responsible of the recent outbreak?

[Q]: The TMEM18 protein's amino acid sequence is well conserved, which suggests that it has retained its function since the divergence of human and plants.
[A]: In what living being can TMEM18 be found?

[Q]: Empagliflozin is a selective sodium glucose cotransporter 2 (SGLT2) inhibitor that inhibits renal glucose reabsorption and is being investigated for the treatment of type 2 diabetes mellitus (T2DM). In this open-label study, the effect of renal impairment on the pharmacokinetics, pharmacodynamics and safety of a 50mg dose of empagliflozin was investigated in 40 subjects, grouped according to estimated glomerular filtration rate (eGFR). Maximum empagliflozin plasma concentrations were similar in subjects with normal renal function and renal impairment. Area under the empagliflozin concentration-time curve (AUC0 - ) values increased by approximately 18, 20, 66 and 48% in subjects with mild, moderate, severe renal impairment and renal failure/end stage renal disease (ESRD), respectively, in comparison to healthy subjects. This was attributed to decreased renal clearance (CLR ). Urinary glucose excretion (UGE) decreased with increasing renal impairment and correlated with decreased eGFR and CLR . Empagliflozin was well tolerated, with no increase in adverse events associated with renal impairment. Renal insufficiency resulted in decreased CLR of empagliflozin, moderately increased systemic exposure and decreased UGE. A single 50mg dose of empagliflozin was well tolerated in subjects with normal renal function and any degree of renal impairment. The pharmacokinetic results of this study indicate that no dose adjustment of empagliflozin is required in patients with renal impairment.
[A]:
Which protein does empagliflozin inhibit?
