Secukinumab demonstrates superior efficacy and a faster response in clearing skin in Asian subjects with moderate to severe plaque psoriasis compared with ustekinumab: Subgroup analysis from the CLEAR study

The 52‐week results from the CLEAR (NCT02074982) study showed high and superior efficacy of secukinumab versus ustekinumab in clearing skin and improving patient‐reported outcomes, with comparable safety profile in subjects with moderate to severe psoriasis. Here, we analyzed the efficacy and safety of secukinumab in Asian subjects from the CLEAR study. In this double‐blind, phase IIIb study, eligible subjects with moderate to severe plaque psoriasis were randomized (1:1) to receive s.c. injection of secukinumab 300 mg or ustekinumab as per label. Of 62 subjects included in Asian subanalyses, 23 were randomized to secukinumab and 39 to ustekinumab. A significantly higher proportion of subjects achieved 90% or more improvement in Psoriasis Area and Severity Index (PASI 90) with secukinumab versus ustekinumab at week 16 (78.3% vs 35.9%, P = 0.0010) and at week 52 (60.9% vs 33.3%, P = 0.0196). Similarly, a higher proportion of subjects achieved PASI 100 with secukinumab versus ustekinumab at week 16 (43.5% vs 10.3%, P = 0.0029) and at week 52 (30.4% vs 12.8%, P = 0.0704). The median time to achieve 50% improvement in baseline PASI was 2.8 weeks in the secukinumab group versus 6.3 weeks in the ustekinumab group. The safety profile of secukinumab was in line with the known profile and no deaths occurred. Overall, 95.7% and 84.6% of subjects remained on secukinumab and ustekinumab, respectively. Similar to the core study, secukinumab showed sustained and superior efficacy with faster response versus ustekinumab, and no new or unexpected safety concerns were identified, in Asian subjects with moderate to severe plaque psoriasis.     

Helicobacter pylori and oral pathology:Relationship with the gastric infection

Helicobacter pylori(H.pylori)has been found in the oral cavity and stomach,and its infection is one of the most frequent worldwide.We reviewed the literature and conducted a Topic Highlight,which identified studies reporting an association between H.pylori-infection in the oral cavity and H.pylori-positive stomach bacterium.This work was designed to determine whether H.pylori is the etiologic agent in periodontal disease,recurrent aphthous stomatitis(RAS),squamous cell carcinoma,burning and halitosis.Record selection focused on the highest quality studies and meta-analyses.We selected 48 articles reporting on the association between saliva and plaque and H.pylori-infection.In order to assess periodontal disease data,we included 12 clinical trials and 1 meta-analysis.We evaluated 13 published articles that addressed the potential association with RAS,and 6 with squamous cell carcinoma.Fourteen publications focused on our questions on burning and halitosis.There is a close relation between H.pylori infection in the oral cavity and the stomach.The mouth is the first extra-gastric reservoir.Regarding the role of H.pylori in the etiology of squamous cell carcinoma,no evidence is still available.     

Tracing Staphylococcus aureus in small and medium-sized food-processing factories on the basis of molecular sub-species typing

Contamination by Staphylococcus aureus of the production environment of three small or medium-sized food-processing factories in Slovakia was investigated on the basis of sub-species molecular identification by multiple locus variable number of tandem repeats analysis (MLVA). On the basis of MLVA profiling, bacterial isolates were assigned to 31 groups. Data from repeated samplings over a period of 3 years facilitated to draw spatial and temporal maps of the contamination routes for individual factories, as well as identification of potential persistent strains. Information obtained by MLVA typing allowed to identify sources and routes of contamination and, subsequently, will allow to optimize the technical and sanitation measures to ensure hygiene.     

Does Body Position Affect Ultrasound Measurements of Bladder-Wall Elasticity?

Ultrasound bladder vibrometry (UBV) parameters have been shown in previous studies to strongly correlate with measurements from urodynamic studies. Just like urodynamic studies, UBV can be performed in supine and sitting positions. The objective of this study is to compare UBV parameters obtained in the two different positions using statistical methods. We recruited eight volunteers with healthy bladders for this purpose. The elasticity, group velocity squared and thickness of the bladder were the UBV parameters of interest, and their values were recorded at different bladder volumes for each volunteer. The results presented indicate that the measurements made in the two positions are in agreement using the Bland–Altman method and a parameter q which compares the values at each bladder volume for each volunteer. UBV parameters were also repeatable for measurements recorded in the supine and sitting positions.

The Complete Nucleotide Sequence of the Carbapenem Resistance-Conferring Conjugative Plasmid pLD209 from a Pseudomonas putida Clinical Strain Reveals a Chimeric Design Formed by Modules Derived from Both Environmental and Clinical Bacteria

The complete sequence of the carbapenem-resistance-conferring conjugative plasmid pLD209 from a Pseudomonas putida clinical strain is presented. pLD209 is formed by 3 well-defined regions: an adaptability module encompassing a Tn402-like class 1 integron of clinical origin containing bla_VIM-2 and aacA4 gene cassettes, partitioning and transfer modules, and a replication module derived from plasmids of environmental bacteria. pLD209 is thus a mosaic of modules originating in both the clinical and environmental (nonclinical) microbiota.     

Twins prematurity – the influence of prenatal surveillance

Objective: To evaluate the influence of the local prenatal surveillance of twin pregnancies in the obstetrical results.

Methods: A prospective cohort study of multiple pregnancies delivered over a period of 16 years in a tertiary centre was conducted. In this study 861 twin pregnancies were included. They were compared for obstetric complications, gestational age at delivery, mode of delivery and birthweight, according to the place of the surveillance.

Results: Of the 861 cases examined, the following obstetric complications were significantly different: metrorrhagia (p?=?0.039), infections (p?p?=?0.007), PROMPT (p?p?=?0.024). The mode of delivery was similar but occurred mostly ≤32 weeks (p?p?Conclusion: Our results demonstrate the crucial importance of prenatal surveillance be carried in a differentiated referral centers with specific/strict protocols or the urgent implementation of same protocols in all other places of surveillance, since this straight surveillance greatly reduces the occurrence of prenatal complications, mainly PROMPT, PTD.
