The coronavirus disease 2019 (COVID-19) pandemic has led to a rapid shift in care delivery models for patients with inflammatory bowel disease (IBD); however, little is known about patient perceptions during this period. We aimed to prospectively evaluate the attitudes, concerns, and health behavior of IBD patients during COVID-19.

An online survey was sent to patients from a tertiary IBD Service. The survey included demographic information and questions about the impact of COVID-19, levels of concern caused by COVID-19, perceived risk of IBD medications, medication cessation, and care delivery preferences.

Of 97 respondents (39%), 95 (98%) reported concern about the impact of COVID-19 on their health, and 43% felt their risk of contracting COVID-19 was above average; 62% reported concern about medication-induced COVID-19 risk, and 11% stopped medications because of COVID-19. Patients considered all medications to increase the risk of COVID-19 susceptibility and severity; 45% preferred telehealth while 16% preferred face-to-face clinic reviews. Preference for IBD monitoring tools in decreasing order was blood testing, stool collection, gastrointestinal ultrasound, magnetic resonance enterography, and then colonoscopy.

Patients with IBD are demonstrated to experience concern related to their diagnosis and medications. The insights provided by the survey are informative for a possible "second-wave" of COVID-19 and routine care, including acceptance of telemedicine, preference for non-invasive investigations, and a need for dissemination of information and education.

We compared access-site complications with a Micropuncture 21-gauge (G) needle to a standard 18G needle in patients undergoing femoral-access percutaneous coronary intervention (PCI).

Vascular access-site complications are the most common complication after cardiac catheterization. These complications increase patient morbidity and mortality, along with healthcare costs.

We retrospectively analyzed a cohort of 17,844 consecutive patients undergoing PCI. Micropuncture access was used in 2344 patients and a standard 18G needle in 15,500 patients. Primary endpoints included vascular perforation or limb ischemia requiring repair, retroperitoneal bleeding, pseudoaneurysm, arteriovenous fistula, groin hematoma (>4 cm).

Patients undergoing PCI with Micropuncture were at higher risk they were on anticoagulation (557 [23.7%] vs. 1,590 [10.2%], p < .001), used steroids more frequently (131 [5.6%] vs. 638 [4.1%], p < .001) and required the use of an intra-aortic balloon pump more often (191 [(8.1%] vs. 896 [5.7%], p < .001). LGH447 Overall, the access-site complications rate was lower using Micropuncture (58 [2.5%]) versus standard needle (558 [3.6%], p = .005). The Micropuncture group had a significantly lower rate of hematoma than standard needle (32 [1.4%] vs. 309 [1.9%], p = .03). There was no significant difference in the rate of limb ischemia (1 [0.04%] vs. 12 [0.07%], p = .56), perforation (2 [0.08%] vs. 14 [0.09%], p = .93), retroperitoneal bleeding (3 [0.12%] vs. 18 [0.11%], p = .87), pseudoaneurysm (18 [0.76%] vs. 170 [1.09%], p = .14), and arteriovenous fistula (2 [0.08%] vs. 35 [0.22%], p = .16), comparing the Micropuncture group to a standard needle, respectively.

Femoral access using a Micropuncture reduced the rate of vascular complications with significant reduction in the rate of groin hematomas.

Here, we report that C. crescentus wild type produces several molecular species of dihydroceramides, which are not produced in a mutant lacking the structural gene for serine palmitoyltransferase (spt). Whereas growth of a spt-deficient mutant and wild type are indistinguishable during the exponential phase of growth, survival of the spt-deficient mutant is much reduced, in comparison with wild type, during stationary phase of growth, especially at elevated temperatures. The structural gene for spt is located within a genomic cluster, comprising another 16 genes and which, like spt, are important for fitness of C. crescentus. Mutants deficient in genes linked to spt by high cofitness were unable to produce dihydroceramide or to survive in stationary phase of growth at elevated temperatures. At least five structural genes are required for dihydroceramide biosynthesis in C. crescentus and sphingolipid biosynthesis is needed for survival of this bacterium and the integrity of its outer membrane.
Omeprazole administration is associated with changes in gastric and fecal microbiota and increased incidence of Clostridioides difficile enterocolitis in humans and dogs.

Study purpose was to assess the effect of omeprazole on gastric glandular and fecal microbiota in healthy adult horses.

Eight healthy horses stabled on straw and fed 100% haylage.

Prospective controlled study. Transendoscopic gastric glandular biopsies, gastric fluid, and fecal samples were obtained from each horse twice at a 7-day interval before the administration of omeprazole. Samples were taken on the same horses before and after a 7-day administration of omeprazole (4 mg/kg PO q24h). pH was assessed on fresh gastric fluid and other samples were kept at -20°C until analysis. Bacterial taxonomy profiling was obtained by V1V3 16S amplicon sequencing from feces and gastric glandular biopsies. Analysis of alpha, beta diversity, and comparison between time points were performed with MOTHUR and results were considered significant when P < .05.

Gastric pH increased significantly after 7 days of omeprazole administration (P = .006). Omeprazole did not induce significant major changes in composition of fecal or gastric glandular microbiota, however, after administration, certain microbial genera became more predominant in the gastric glandular mucosa (lower Simpson's evenness, P = .05). Only the genus Clostridium sensu strictu_1 had a significant shift in the glandular gastric mucosa after omeprazole administration (P = .002). No population shifts were observed in feces.

Oral administration of omeprazole could have fewer effects in gastrointestinal microbiota in the horse compared to other species.

To evaluate the use of the caudal vena cava collapsibility index (CVCCI) as a predictor of fluid responsiveness in hospitalized, critically ill dogs with hemodynamic or tissue perfusion abnormalities.

Retrospective observational study.

Private referral center.

Twenty-seven critically ill, spontaneously breathing dogs with compromised hemodynamics or tissue hypoperfusion.

None.

The electronic medical records were searched for dogs admitted for any cause, from August 2016 to December 2017. We included dogs with ultrasound measurements of CVCCI, performed at baseline; and velocity time integral (VTI) of the subaortic blood flow, carried out before and after a fluid load. CVCCI was estimated as (maximum diameter-minimum diameter/maximum diameter) × 100. Dogs in which VTI increased ≥15% were considered fluid responders. The CVCCI accurately predicted fluid responsiveness with an area under the receiver operating characteristic curve of 0.96 (95% CI, 0.88 to 1.00). The optimal cut-off of CVCCI that bettritically ill dogs with perfusion abnormalities. Further research is necessary to extrapolate these results to larger populations of hospitalized dogs.
The Bipolar at Risk Trial (BART) was a feasibility randomized controlled trial investigating cognitive behavioral therapy (CBT) compared with treatment as usual (TAU) in young people at high risk of developing bipolar disorder (BD). This qualitative study aimed to investigate participants' experiences of trial involvement, and the acceptability of CBT for this population.

Participants were those identified as being at risk of bipolar disorder, determined by current symptoms or family history. A purposive sample of twenty-one participants from both the intervention and TAU arms of the trial was recruited.

Twenty-one semi-structured interviews were conducted by service user researchers (13 participants had received therapy and 8 TAU). Interviews were audio recorded with consent from participants and transcribed verbatim. NVivo 11 Pro software was used to conduct an inductive thematic analysis.

Super-ordinate themes were "adaptability and flexibility," "feeling understood and valued," and "relevance of serceived as helpful in ways that were personal to each participant.
Young people at risk of bipolar disorder value a flexible approach to assessments and therapy, developing a rapport with research assistants and therapists and opening up to them when they feel comfortable to do so. CBT focusing on coping with mood swings was acceptable to the majority of participants who received it and it was perceived as helpful in ways that were personal to each participant.The biorelevant PyFALGEA oligopeptide ligand, which is selective towards the epidermal growth factor receptor (EGFR), has been successfully employed as a substrate in magnetic resonance signal amplification by reversible exchange (SABRE) experiments. It is demonstrated that PyFALGEA and the iridium catalyst IMes form a PyFALGEAIMes molecular complex. The interaction between PyFALGEAIMes and H2 results in a ternary SABRE complex. Selective 1D EXSY experiments reveal that this complex is labile, which is an essential condition for successful hyperpolarization by SABRE. Polarization transfer from parahydrogen to PyFALGEA is observed leading to significant enhancement of the 1 H NMR signals of PyFALGEA. link3 Different iridium catalysts and peptides are inspected to discuss the influence of their molecular structures on the efficiency of hyperpolarization. It is observed that PyFALGEA oligopeptide hyperpolarization is more efficient when an iridium catalyst with a sterically less demanding NHC ligand system such as IMesBn is employed. Experiments with shorter analogues of PyFALGEA, that is, PyLGEA and PyEA, show that the bulky phenylalanine from the PyFALGEA oligopeptide causes steric hindrance in the SABRE complex, which hampers hyperpolarization with IMes. Finally, a single-scan 1 H NMR SABRE experiment of PyFALGEA with IMesBn revealed a unique pattern of NMR lines in the hydride region, which can be treated as a fingerprint of this important oligopeptide.
