Clinical Phenotyping of Primary Sjogren Syndrome Patients Using Salivary Gland Ultrasonography:Data From the RESULT Cohort
Objective. To investigate salivary gland ultrasound (SGUS) abnormalities in relation to clinical phenotype and patient characteristics, disease activity, and disease damage in patients with primary Sjogren syndrome (pSS). Methods. Consecutive outpatients included in our REgistry of Sjogren Syndrome LongiTudinal (RESULT) cohort were selected. Patients with pSS who were included were classified according to the American College of Rheumatology/European League Against Rheumatism (EULAR) criteria and underwent full ultrasonographic examination (However score 0-48) at baseline. Total SGUS scores of >= 15 were considered positive. Patient characteristics, disease activity, and disease damage were compared between the different SGUS groups. Results. In total, 172 of 186 patients with pSS were eligible, of whom 136 (79%) were SGUS positive. Compared with patients who were SGUS negative, SGUS-positive patients had significantly longer disease duration, higher EULAR Sjogren Syndrome Disease Activity Index, higher Sjogren Syndrome Disease Damage Index, and were more likely to have a positive parotid gland biopsy, anti-SSA/SSB antibodies, and abnormal unstimulated whole saliva (UWS) and ocular staining score (OSS), and higher levels of IgG and rheumatoid factor. Regarding patient-reported outcome measurements (PROM), patients who were SGUS positive scored significantly lower on the EULAR Sjogren Syndrome Patient-Reported Index for fatigue and pain, and more often found their disease state acceptable compared with patients who were SGUS negative. SGUS total score showed significant associations with various clinical and serological variables, and with PROM. Highest associations were found for UWS (p = -0.551) and OSS (p = 0.532). Conclusion. Patients who were SGUS positive show a distinct clinical phenotype in all aspects of the disease compared with patients who were SGUS negative: clinical, functional, serological, and PROM. SGUS could be a helpful tool in selecting patients for clinical trials and estimating treatment need
Defining Multidrug Resistance of Gram-Negative Bacteria in the Dutch-German Border Region-Impact of National Guidelines
Preventing the spread of multidrug-resistant Gram-negative bacteria (MDRGNB) is a public health priority. However, the definition of MDRGNB applied for planning infection prevention measures such as barrier precautions differs depending on national guidelines. This is particularly relevant in the Dutch–German border region, where patients are transferred between healthcare facilities located in the two different countries, because clinicians and infection control personnel must understand antibiograms indicating MDRGNB from both sides of the border and using both national guidelines. This retrospective study aimed to compare antibiograms of Gram-negative bacteria and classify them using the Dutch and German national standards for MDRGNB definition. A total of 31,787 antibiograms from six Dutch and four German hospitals were classified. Overall, 73.7% were no MDRGNB according to both guidelines. According to the Dutch and German guideline, 7772/31,787 (24.5%) and 4586/31,787 (12.9%) were MDRGNB, respectively (p < 0.0001). Major divergent classifications were observed for extended-spectrum β-lactamase (ESBL) -producing Enterobacteriaceae, non-carbapenemase-producing carbapenem-resistant Enterobacteriaceae, Pseudomonas aeruginosa and Stenotrophomonas maltophilia. The observed differences show that medical staff must carefully check previous diagnostic findings when patients are transferred across the Dutch–German border, as it cannot be assumed that MDRGNB requiring special hygiene precautions are marked in the transferred antibiograms in accordance with both national guidelines
Abatacept treatment for patients with early active primary Sjogren's syndrome:a single-centre, randomised, double-blind, placebo-controlled, phase 3 trial (ASAP-III study)
Background: Several small open-label studies have suggested efficacy of abatacept—a co-stimulation inhibitor—in patients with primary Sjögren's syndrome. These promising results warranted further evaluation. We therefore aimed to further assess the safety and efficacy of abatacept compared with placebo in patients with primary Sjögren's syndrome. Methods: We did a single-centre, randomised, double-blind, placebo-controlled, phase 3 trial at the University Medical Center Groningen (Groningen, Netherlands). We included patients with primary Sjögren's syndrome fulfilling the American–European Consensus Group criteria, aged 18 years or older, with positive salivary gland biopsies, time from diagnosis of 7 years or less, and a European League Against Rheumatism Sjögren's Syndrome Disease Activity Index (ESSDAI) score of 5 or more. Independent pharmacists randomly allocated patients (1:1) to either the abatacept group or placebo group using a computer-generated sequence stratified by previous use of disease-modifying anti-rheumatic drugs. Patients received at-home subcutaneous injections of abatacept (125 mg) or placebo once a week for 24 weeks. The primary outcome was the between-group difference in ESSDAI score at week 24. Efficacy was analysed in patients who received at least one drug dose and for whom post-baseline data were collected. Safety was analysed in all patients who received at least one drug dose. Findings: Between Aug 14, 2014, and Aug 23, 2018, 580 patients were reviewed for eligibility, of which 80 patients were randomly assigned to receive study treatment. Efficacy was analysed in 40 patients receiving abatacept and 39 patients receiving placebo (one patient in this group was lost to follow-up). The primary outcome did not significantly differ between the treatment groups. The adjusted mean difference in ESSDAI score at week 24 between the abatacept group and placebo group was −1·3 (95% CI −4·1 to 1·6). No deaths or treatment-related serious adverse events occurred. In 38 (95%) of 40 patients in the abatacept group, 103 adverse events occurred, including one serious adverse event and 46 infections. In 38 (95%) of 40 patients in the placebo group, 87 adverse events occurred, including four serious adverse events and 49 infections. Interpretation: On the basis of this trial, we cannot recommend abatacept treatment as standard of care to reduce systemic disease activity in patients with primary Sjögren's syndrome. Further studies should evaluate whether patients with specific clinical manifestations and biological characteristics might benefit from abatacept treatment. Funding: Bristol-Myers Squibb
Epidemiology of Extended-Spectrum beta-Lactamase-Producing E-coli and Vancomycin-Resistant Enterococci in the Northern Dutch-German Cross-Border Region
Objectives: To reveal the prevalence and epidemiology of extended-spectrum β-lactamase (ESBL)- and/or plasmid AmpC (pAmpC)- and carbapenemase (CP) producing Enterobacteriaceae and vancomycin-resistant enterococci (VRE) across the Northern Dutch–German border region.Methods: A point-prevalence study on ESBL/pAmpC/CP producing Enterobacteriaceae and VRE was carried out in hospitalized patients in the Northern Netherlands (n = 445, 2012–2013) and Germany (n = 242, 2012). Healthy individuals from the Dutch community (n = 400, 2010–2012) were also screened. In addition, a genome-wide gene-by-gene approach was applied to study the epidemiology of ESBL-Escherichia coli and VRE.Results: A total of 34 isolates from 27 patients (6.1%) admitted to Dutch hospitals were ESBL/pAmpC positive and 29 ESBL-E. coli, three pAmpC-E. coli, one ESBL-Enterobacter cloacae, and one pAmpC-Proteus mirabilis were found. In the German hospital, 18 isolates (16 E. coli and 2 Klebsiella pneumoniae) from 17 patients (7.7%) were ESBL positive. In isolates from the hospitalized patients CTX-M-15 was the most frequently detected ESBL-gene. In the Dutch community, 11 individuals (2.75%) were ESBL/pAmpC positive: 10 ESBL-E. coli (CTX-M-1 being the most prevalent gene) and one pAmpC E. coli. Six Dutch (1.3%) and four German (3.9%) hospitalized patients were colonized with VRE. Genetic relatedness by core genome multi-locus sequence typing (cgMLST) was found between two ESBL-E. coli isolates from Dutch and German cross-border hospitals and between VRE isolates from different hospitals within the same region.Conclusion: The prevalence of ESBL/pAmpC-Enterobacteriaceae was similar in hospitalized patients across the Dutch–German border region, whereas VRE prevalence was slightly higher on the German side. The overall prevalence of the studied pathogens was lower in the community than in hospitals in the Northern Netherlands. Cross-border transmission of ESBL-E. coli and VRE seems unlikely based on cgMLST analysis, however continuous monitoring is necessary to control their spread and stay informed about their epidemiology
Targeting the Wolbachia Cell Division Protein FtsZ as a New Approach for Antifilarial Therapy
Filarial nematode parasites are responsible for a number of devastating diseases in humans and animals. These include lymphatic filariasis and onchocerciasis that afflict 150 million people in the tropics and threaten the health of over one billion. The parasites possess intracellular bacteria, Wolbachia, which are needed for worm survival. Clearance of these bacteria with certain antibiotics leads to parasite death. These findings have pioneered the approach of using antibiotics to treat and control filarial infections. In the present study, we have investigated the cell division process in Wolbachia for new drug target discovery. We have identified the essential cell division protein FtsZ, which has a GTPase activity, as an attractive Wolbachia drug target. We describe the molecular characterization and catalytic properties of the enzyme and demonstrate that the GTPase activity is inhibited by the natural product, berberine, and small molecule inhibitors identified from a high-throughput screen. We also found that berberine was effective in reducing motility and reproduction in B. malayi parasites in vitro. Our results should facilitate the discovery of selective inhibitors of FtsZ as a novel antibiotic approach for controlling filarial infection
Diabetic Nutrition Education Intervention for Low-Income Patients with Type 2 Diabetes
Type 2 diabetes is a chronic disease that affects a multitude of people in the United States especially those in lower socioeconomic strata. Low income earning adults have higher rates of diabetes and increased risk of complications such as heart disease, stroke, neuropathy, nephropathy, and retinopathy. Diabetes nutrition education is considered to be an important aspect in the care plan of adults with Type 2 diabetes. However, many times low-income patients are not able to afford this care. The use of diabetes nutrition counseling provided at a Midwest community health clinic became a viable solution to meet this need for diabetes nutrition education and knowledge of appropriate foods that lead to improved glycemic control for participants. Implementation of an in-clinic diabetic nutrition education program increased knowledge regarding nutrition for patients with Type 2 diabetes empowering adults to make informed choices regarding their nutrition
Effect of Oral Care and Health Professional Education on Ventilator Acquired Pneumonia: A Pilot Study
Ventilator acquired pneumonia (VAP) is a nosocomial infection that is a major cause of morbidity and mortality in the critical care environment. Procedures and protocols are being researched in order to reduce the risk associated with this nosocomial infection for patients who require mechanical ventilation. The use of oral care hygiene equipment such as toothbrushes, along with staff education, has been shown to reduce the incidence of VAP. This study was conducted on a 39 bed critical care unit in a Midwestern Level 2 Trauma Center. Patients included in the study met the requirements of mechanical ventilation for 24 hours without ta diagnosis of pneumonia and were 18 years of age or older. The investigator educated critical care staff regarding risk factors and cause of ventilator acquired pneumonia. The staff also received hands on training by the investigator concerning proper oral hygiene and techniques for mechanically ventilated patients. The hospital\u27s infection control officer monitored the incidence of ventilator acquired pneumonia and compared the VAP rate for the study period with the rate from the previous year. A clinically significant reduction of ventilator acquired pneumonia was shown after the education and hands on training of the staff by the investigator. As a result, the critical care unit has updated the policy and standard operating procedure (SOP) for the oral care of mechanically ventilated patients. This study showed the benefits of oral care on mechanically ventilated patients in reducing the incidence of VAP leading to better patient outcomes and hospital stay cost reduction
Impact of Infection Control Education on Gastrointestinal Endoscopy Procedural Staff
To date, minimal research has been conducted on proper use of personal protective equipment and hand hygiene within endoscopy. The American Society for Gastrointestinal Endoscopy has developed guidelines for infection control within the endoscopy suite. A practice change based upon these guidelines was implemented. Education was provided to endoscopy procedural staff within a Midwestern hospital based upon the World Health Organization 5 Moments for Hand Hygiene initiative and included personal protective equipment. Knowledge, skills, and attitudes of the participant group were compared from paired pre- to posteducation surveys pertaining to hand hygiene and personal protective equipment. Observation of personal protective equipment use and hand hygiene implementation during procedures was also documented pre- to posteducation. The project results revealed both willingness to implement proper donning and doffing of personal protective equipment and improved technique as evidenced by improved observed technique with the endoscopy suite and moderately improved hand hygiene questionnaire results. Although conducted as a quality improvement project, clinical significance was found via observation following education. These practices can aid in reduction of organism transmission from patients to staff [...
