Quality of design and reporting of animal research in peritoneal dialysis: A scoping review

The concerns about reproducibility and validity of animal studies are partly related to poor experimental design and reporting. Here, we undertook a scoping review of the literature to determine the extent and quality of reporting of animal studies on peritoneal dialysis (PD). Online databases were searched to identify 567 relevant original articles published between 1979 and 2018. These were analyzed with respect to bibliographic parameters and general aspects of animal experimentation. A subgroup of 120 studies was analyzed in detail in terms of the impact on the reporting quality of the Animal Research: Reporting of In Vivo Experiments (ARRIVE) guidelines for animal studies. The number of animal studies on PD increased continuously over the years with a thematic shift toward long-term preservation of the peritoneum as a dialyzing organ. There were significant deficiencies in research design with the lack of sample size estimation, randomization, and blinding being the commonest shortcomings. The description of animal numbers, housing conditions, use of medication, and statistical analysis was incomplete. The introduction in 2010 of the ARRIVE guidelines produced very little improvement in the completeness of reporting regardless of journal impact factor. The animal studies on PD suffer from deficits in experimental protocols and transparent reporting. These drawbacks need to be corrected to ensure high-quality and much-needed animal research in PD.
Metabolomic Profiling of Left Ventricular Diastolic Dysfunction in Women With or at Risk for HIV Infection: The Women's Interagency HIV Study

Background People living with HIV have an increased risk of left ventricular diastolic dysfunction (LVDD) and heart failure. HIV‐associated LVDD may reflect both cardiomyocyte and systemic metabolic derangements, but the underlying pathways remain unclear. Methods and Results To explore such pathways, we conducted a pilot study in the Bronx and Brooklyn sites of the WIHS (Women's Interagency HIV Study) who participated in concurrent, but separate, metabolomics and echocardiographic ancillary studies. Liquid chromatography tandem mass spectrometry–based metabolomic profiling was performed on plasma samples from 125 HIV‐infected (43 with LVDD) and 35 HIV‐uninfected women (9 with LVDD). Partial least squares discriminant analysis identified polar metabolites and lipids in the glycerophospholipid‐metabolism and fatty‐acid‐oxidation pathways associated with LVDD. After multivariable adjustment, LVDD was significantly associated with higher concentrations of diacylglycerol 30:0 (odds ratio [OR], 1.60, 95% CI [1.01–2.55]); triacylglycerols 46:0 (OR 1.60 [1.04–2.48]), 48:0 (OR 1.63 [1.04–2.54]), 48:1 (OR 1.62 [1.01–2.60]), and 50:0 (OR 1.61 [1.02–2.53]); acylcarnitine C7 (OR 1.88 [1.21–2.92]), C9 (OR 1.99 [1.27–3.13]), and C16 (OR 1.80 [1.13–2.87]); as well as lower concentrations of phosphocholine (OR 0.59 [0.38–0.91]). There was no evidence of effect modification of these relationships by HIV status. Conclusions In this pilot study, women with or at risk of HIV with LVDD showed alterations in plasma metabolites in the glycerophospholipid‐metabolism and fatty‐acid‐oxidation pathways. Although these findings require replication, they suggest that improved understanding of metabolic perturbations and their potential modification could offer new approaches to prevent cardiac dysfunction in this high‐risk group.
Alpha-1 antitrypsin inhibits formaldehyde-induced apoptosis of human peritoneal mesothelial cells

Background: The alpha-1 antitrypsin (AAT) protein has an important role in the anti-inflammatory and apoptotic response. AAT inhibits not only serine proteases but also cysteine and aspartic proteases. Apoptosis results from the sequential activation of cysteine proteases of the caspase family. This study aimed to evaluate the effect of AAT on formaldehyde-induced apoptosis of human peritoneal mesothelial cells (HPMCs). Methods: HPMCs were cultured and treated with formaldehyde (250 µM) to induce apoptosis. In the AAT group, the cultured HPMCs were pretreated with AAT (2 mg/mL) for 1 h before formaldehyde treatment. We used 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays to determine cell viability, and flow cytometry and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assays to detect apoptosis. The MTT assays were used to find optimal concentrations of formaldehyde and AAT. We measured caspase-3 activity and used Western blotting to estimate Bcl-2 and Bad expression. Results: Flow cytometry and TUNEL assays revealed that formaldehyde exposure significantly increased apoptosis compared with the control treatment, but pretreatment with AAT significantly inhibited this effect. Compared with the control, caspase-3 activity was significantly increased and the ratio of Bcl-2 to Bad expression significantly decreased following treatment with formaldehyde. However, caspase-3 activity was significantly lower and the Bcl-2 to Bad expression ratio higher in the AAT group than in the formaldehyde-only group. Conclusion: AAT inhibits formaldehyde-induced apoptosis of HPMCs via a caspase-mediated pathway. These data support a potential use for AAT as a therapeutic agent for the inhibition of peritoneal cell apoptosis during peritoneal dialysis.
The prognostic importance of VEGF-A, PDGF-BB and c-MET in patients with metastatic colorectal cancer

Abstract Introduction We aimed to assess the effect of VEGF-A, PDGF-BB, and c-Met expression levels on survival in patients with metastatic colorectal cancer receiving bevacizumab therapies. Patients and methods A total of 105 patients diagnosed with metastatic colorectal cancer between the years 2006 and 2016 were included in the research retrospectively. Results The progression-free survival (PFS) durations of patients with high expression levels of VEGF-A and with low expression levels of VEGF-A were 11 months and 10 months (p = 0.44), respectively. The PFS durations of patients with high PDGF-BB expression and low PDGF-BB expression were 12 months and 10 months (p = 0.16), respectively, while the PFS durations of patients with high and low c-Met expression were 8 months and 13 months (p = 0.005), respectively. Metastatic overall survival was 27 months and 18 months (p = 0.05) in patients with high and low VEGF-A expression levels, respectively, 31 months and 21 months (p = 0.16) in patients with high and low PDGF-BB expression levels, respectively, and 21 months and 26 months (p = 0.11) in patients with high and low c-Met expression levels, respectively. Conclusion The results of this research revealed a high c-Met expression relationship with worse PFS and low VEGF-A expression associated with poor metastatic overall survival in patients with metastatic colorectal cancer receiving bevacizumab therapies.
Efficient 1-Hour Technetium-99 m Pyrophosphate Imaging Protocol for the Diagnosis of Transthyretin Cardiac Amyloidosis

Background: Technetium-99 m pyrophosphate protocols for transthyretin cardiac amyloidosis diagnosis have variably used 1- and 3-hour imaging time points. We investigated whether imaging at 1 hour with superior efficiency had comparable diagnostic accuracy as 3-hour imaging. Methods: This is a registry analysis of patients with suspected transthyretin cardiac amyloidosis referred for technetium-99 m pyrophosphate at a single tertiary center from June 2015 through January 2019. Patients underwent planar and single-photon emission computed tomography (SPECT) imaging at 1 and 3 hours. A positive Tc-99m pyrophosphate study was defined by the presence of diffuse myocardial tracer uptake on SPECT. For planar imaging, visual semiquantitative (grades 0-3, ≥2 considered positive) and quantitative heart to contralateral ratios (≥1.5 considered positive) were used. Results: Two hundred thirty-three patients (69% men; median age, 77 [69–83] years) underwent the study protocol. There were 60 (25.8%) patients with diffuse myocardial uptake, 1 (0.4%) with regional uptake, and 172 (73.8%) with no myocardial uptake. Results of SPECT were identical at 1 and 3 hours. Planar imaging at 1 hour had 98% sensitivity and 96% specificity. Planar grade 0 uptake or heart to contralateral ratio ≤1.2 and planar grade 3 uptake or heart to contralateral ratio ≥2.0 were always associated with negative and positive SPECT, respectively. For planar grades 1 and 2 uptake and heart to contralateral ratio 1.3 to 1.9, SPECT was needed to make a diagnosis. No patient with light-chain cardiac amyloidosis had positive SPECT. Conclusions: An efficient 1-hour technetium-99 m pyrophosphate protocol had comparable diagnostic performance to a 3-hour protocol.
Noninvasive Continuous Monitoring of Vital Signs With Wearables: Fit for Medical Use?

Background: Wearables (= wearable computer) enable continuous and noninvasive monitoring of a range of vital signs. Mobile and cost-effective devices, combined with powerful data analysis tools, open new dimensions in assessing body functions (“digital biomarkers”). Methods: To answer the question whether wearables are ready for use in the medical context, a PubMed literature search and analysis for their clinical-scientific use using publications from the years 2008 to 2018 was performed. Results: A total of 79 out of 314 search hits were publications on clinical trials with wearables, of which 16 were randomized controlled trials. Motion sensors were most frequently used to measure defined movements, movement disorders, or general physical activity. Approximately 20% of the studies used sensors to detect cardiovascular parameters. As for the sensor location, the wrist was chosen in most studies (22.8%). Conclusion: Wearables can be used in a precisely defined medical context, when taking into account complex influencing factors.
Clinical significance of radiological patterns of HRCT and their association with macrophage activation in dermatomyositis.

OBJECTIVES To evaluate the distribution of radiological characteristics stratified by different myositis-specific autoantibodies, identify prognostic value of high-resolution CT (HRCT) patterns in DM-associated interstitial lung disease (DM-ILD), and explore the possible mechanism associated with macrophage activation. METHODS We enrolled 165 patients with PM/DM-ILD. The distribution of HRCT radiological types with different myositis-specific autoantibodies and the relationship between radiological features and ILD course and prognosis were analysed. Additionally, the potential role of macrophage activation in rapidly progressive ILD (RP-ILD) with DM was studied. RESULTS The organizing pneumonia pattern was dominant in HRCT findings of patients with DM-ILD, especially those with anti-SAE (6/6, 100%) and anti-MDA5 (46/62, 74.2%) antibodies. The ratios of organizing pneumonia and nonspecific interstitial pneumonia patterns were almost equal in patients with aminoacyl tRNA synthetase antibodies, and nonspecific interstitial pneumonia pattern was associated with a mild clinical course. Lower lung zone consolidation in HRCT was related to RP-ILD in both anti-MDA5 and anti-aminoacyl tRNA synthetase antibody-positive groups. Ferritin levels of >1000 ng/ml (odds ratio (OR), 12.3; P=0.009), elevated carcinoembryonic antigen (OR, 5.8; P=0.046) and carbohydrate antigen 19-9 (OR, 7.8; P=0.018) were independent predictors of a lower lung zone consolidation pattern in anti-MDA5 antibody-positive DM. The infiltration of CD163-positive macrophages into alveolar spaces was significantly higher in the DM-RP-ILD group than in the chronic DM-ILD group. CONCLUSION HRCT patterns are different among variable myositis-specific autoantibodies positive patients with ILD and lower zone consolidation in HRCT correlated with RP-ILD in DM. Activated macrophages may contribute to the pathogenesis of RP-ILD in DM.
Reliability and Validity of the Turkish Reintegration to Normal Living Index in Amputees

In our country, outcome measures are needed to evaluate the results of occupational therapy in amputees. This study aimed to cross-culturally adapt the Reintegration to Normal Living Index (RNLI) and to evaluate the reliability and validity of a Turkish version of the RNLI. The Turkish version of the RNLI was applied to 120 amputees. Cronbach’s alpha coefficient and the intraclass correlation coefficient (ICC) were used to determine internal consistency and test–retest reliability, respectively. Criterion validity was assessed using Short Form 36 (SF-36). The Turkish version of the RNLI presented reliable results in repeated assessments (ICC = .88), and the internal consistency of the RNLI was high (Cronbach’s α coefficient = .89). A statistically significant relationship was found between RNLI and SF-36 (p < .05). The Turkish RNLI is a reliable and valid tool to evaluate the level of reintegration to normal living for amputees.
Blastic plasmacytoid dendritic cell neoplasm: First retrospective study in the Czech Republic.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy with aggressive behavior and poor prognosis. We present the first retrospective analysis mapping its incidence and therapeutic outcomes in patients diagnosed and treated from 2000 to 2017 in the Czech Republic. The cohort comprised 14 patients (10 males, 4 females) with a median age at diagnosis of 39 years (range, 5-68 years). Initially, skin involvement was noted in 10 (71%) patients and bone marrow infiltration was present in 9 (64%). The first complete remission was achieved in 6/14 (43%) patients after acute lymphoblastic leukemia/lymphoma induction therapy and in 3/14 (21%) patients after acute myeloid leukemia regimen. Nine patients underwent allogeneic hematopoietic cell transplantation, with two patients achieving the first complete remission only after allogeneic transplantation. Patients undergoing allogeneic hematopoietic cell transplantation had a longer overall survival than those treated without transplantation (the median survival over the period 16.4 vs. 8.1 months). Relapse of the disease was a significant predictor of mortality (p = 0.05). Over the study period, patients' survival ranged from 3.3 to 44.2 months, with a median overall survival of 13 months. Our results revealed an effectivity of allogeneic hematopoietic cell transplantation on complete remission achievement in refractory/relapsed disease. The study aimed to present the actual data from the Czech Republic and thus contribute to a global understanding of BPDCN.
Incremental peritoneal dialysis

Incremental peritoneal dialysis (PD) has been variably defined. It involves taking advantage of the residual renal function that is usually present at initiation of dialysis to initially prescribe less onerous lower doses of PD while still achieving individualized clearance goals. We propose that incremental PD be defined as a strategy, rather than a particular regime, in which: (1) less than standard “full-dose” PD is initially prescribed in recognition of the value of residual renal function; (2) peritoneal clearance is initially less than the individualized clearance goal but the combination of peritoneal plus renal clearance achieves or exceeds that goal clearance; and (3) there is a clear intention to increase dose of PD as renal clearance declines and/or symptoms appear. Incremental PD by its nature lessens the workload of dialysis for those doing PD, reduces cost and exposure of the peritoneal membrane to glucose, and may lessen mechanical symptoms. Evidence that incremental PD improves clinical outcomes compared to the use of full-dose PD is lacking but one randomized controlled trial, multiple observational studies, and a systematic review all suggest that outcomes are at least as good. Given that incremental PD costs less and is inherently less onerous, it is reasonable, pending larger randomized trials, to adopt this strategy.
Assessing the Mental Health of Refugees Using the Refugee Health Screener-15

In 2017, 352 refugees were relocated to the Kansas City, Kansas area. As part of the relocation process, newly arrived refugees receive physical and mental health screenings. This study is a retrospective analysis of the results of 92 Refugee Health Screener-15 (RHS-15) surveys collected from February to December 2017 and interviews with the healthcare providers who administered the surveys in a primary care clinic. The most commonly reported mental health symptoms included the following: too much thinking or too many thoughts; muscle, bone, or joint pain; and crying easily. Thirty-seven refugee surveys (40%) indicated the need for follow-up mental health screening. A significant small correlation (r = .22, p = .03) was found between female gender and the depression subscale of mental health symptoms. Provider interviews revealed challenges associated with conducting mental health screening of newly arrived refugees in a primary care setting.
The effect of nitrogen dioxide on low birth weight in women with inflammatory bowel disease: a Norwegian pregnancy cohort study (MoBa)

Abstract Background: Adverse birth outcomes are more frequent among mothers with inflammatory bowel diseases (IBDs) than non-IBD mothers. In recent studies, air pollution, such as high concentrations of nitrogen dioxide (NO2), is reckoned as a risk factor for preterm birth in the general population. In this study, we investigated whether IBD mothers are at higher risk of preterm birth when exposed to NO2 compared to non-IBD mothers. Methods: We used information from the Norwegian Mother, Father and Child Cohort Study (MoBa). The pregnancy cohort was linked to the Norwegian Medical Birth Registry and air-pollution exposure data available from a subset of the study cohort. The relevant outcome in this study was preterm birth. A total of 16,170 non-IBD and 92 IBD mothers were included in the study. Results: The mean exposure of NO2 during the pregnancy was similar for IBD and non-IBD mothers, 13.7 (6.9) μg/m3 and 13.6 (4.2) μg/m3, respectively. IBD mothers with higher exposure of NO2 in the second and third trimester were at significant risk of preterm birth compared to non-IBD mothers [OR = 1.28 (CI 95%: 1.04–1.59) and OR = 1.23 (95% CI: 1.06–1.43), respectively]. The mean NO2 exposure was significantly higher in IBD mothers with preterm birth than in IBD mothers who delivered at term, at 19.58 (1.57) μg/m3 and 12.89 (6.37) μg/m3, respectively. Conclusions: NO2 exposure influenced the risk of preterm birth in IBD mothers. Higher risk of preterm birth in IBD was associated with higher exposure of NO2, suggesting vulnerability of preterm birth in IBD when exposed to NO2.
Effect of Exercise and Meals on Continuous Glucose Monitor Data in Healthy Individuals Without Diabetes

Objective: The aim of these analyses was to characterize the effect of exercise and meals on glucose concentrations in healthy individuals without diabetes. Methods: Healthy individuals without diabetes (age ≥6 years) with nonobese body mass index were enrolled at 12 centers within the T1D Exchange Clinic Network. Participants wore a blinded Dexcom G6 for up to ten days. Throughout this sensor wear, participants completed a daily log indicating times and type of any exercise and start times of meals and snacks. Results: A total of 153 participants (age 7-80 years) were included in the analyses. Exercise induced a mean change of −15 ± 18 mg/dL from baseline to nadir sensor glucose level. Mean nadir glucose concentration during nights following exercise days was 82 ± 11 mg/dL compared with 85 ± 11 mg/dL during nights following nonexercise days (P = .05). Mean change from baseline to nadir sensor glucose level during aerobic exercise was −15 ± 18 and −9 ± 12 mg/dL for resistance exercise (P = .25). Overnight nadir glucose during nights following aerobic and resistance exercise was 83 ± 12 and 76 ± 14 mg/dL, respectively (P = .25). Overall mean peak postprandial glucose per participant increased from 93 ± 10 mg/dL premeal to 130 ± 13 mg/dL with an average time to peak glucose per participant of 97 ± 31 minutes. Consumption of alcohol on the day prior did not impact overnight mean or nadir glucose. Conclusion: The present analysis provides important data characterizing the effect of exercise and meals on glucose in healthy individuals without diabetes. These data provide a repository to which future therapies, whether pharmacologic or technologic, can be compared.
Polycythemia associated with renal fibrosarcoma in a dog.

: A 10-year-old Beagle-type dog with intermittent vomiting and anorexia had an absolute polycythemic condition. A renal mass was detected and removed by total nephrectomy. After surgery, the hematologic values returned to normal, suggesting that the tumor was the cause of the polycythemia. The histologic diagnosis was fibrosarcoma. In dogs, secondary polycythemia has otherwise been reported with renal carcinoma and lymphosarcoma.
Is Therapeutic Drug Monitoring for Anti-Tumor Necrosis Factor Agents in Adults with Inflammatory Bowel Disease Ready for Standard of Care?: A Systematic Review and Meta-analysis.

INTRODUCTION Utilizing therapeutic drug monitoring (TDM) in adult patients with IBD remains controversial. We conducted a systematic review and meta-analysis to answer four clinical PICO questions. METHODS We searched MEDLINE, Embase, Web of Science, and Cochrane Central from inception to June 30, 2019. Remission was defined by the manuscripts' definitions of clinical remission. Data was analyzed using RevMan 5.3. Quality of evidence was assessed with GRADE methodology. RESULTS We identified and screened 3365 abstracts and 11 articles.PICO 1 Reactive vs No TDM: six studies pooled showed 57.1% (257/450) failed to achieve remission following reactive TDM versus 44.7% (268/600) in the no TDM group (RR:1.14; 95% CI 0.88-1.47). PICO 2 Proactive vs no TDM: five studies pooled showed 19.5% (75/384) failed to maintain remission in the proactive TDM group versus 33.4% (248/742) in the no TDM group (RR:0.60, 95% CI 0.35-1.04). PICO 3 Proactive vs Reactive TDM: two retrospective studies pooled showed 14.2% (26/183) failure to maintain remission in the proactive TDM group and 64.7% (119/184) in the reactive TDM group (RR:0.22; 95%CI 0.15-0.32). PICO 4 TDM (proactive/reactive) vs No TDM: we pooled ten studies showing 39.7% (332/837) failed to achieve remission in the TDM (proactive/reactive) cohort versus 40.3% (428/1063) in the no TDM cohort (RR:0.94; 95% CI 0.77-1.14). Overall, the quality of evidence in each PICO was very low using GRADE. CONCLUSION This meta-analysis shows that data supporting use of TDM in adults is limited and very low quality. Further well designed RCTs are needed to determine the place of TDM in clinical practice.
Social anxiety and perceptions of likeability by peers in children

The current study aimed to investigate the discrepancy between self‐reported and peer‐reported likeability among children, and the relation with social anxiety, depression, and social support. In total, 532 children between 7 and 12 years completed questionnaires about social anxiety symptoms, depressive symptoms, and social support, estimated their own likeability, and indicated how much they liked their classmates. Children with higher levels of social anxiety or depression overestimated their likeability less or even underestimated their likeability. Social anxiety symptoms, but not depressive symptoms, were significant predictors of the discrepancy. Social support was positively related to likeability and negatively related to social anxiety, but did not moderate the association between social anxiety symptoms and perception accuracy of likeability. These results are in line with cognitive theories of childhood social anxiety, and they stress the importance of using multi‐informant measures when studying the relation between social anxiety and social functioning in children.
