Notes

FDG/PET-CT results in a initial number of 15 patients using polyarteritis nodosa.
Testing of the proband for sarcomeric mutations and phenocopies was initially negative. After eight years of clinical follow-up, the suspicion of an undiscovered pathogenic gene mutation shared among the members of this family led us to enroll the proband in a whole-genome sequencing research project, which revealed a heterozygous pathogenic intronic MYBPC3 variant (c.1227-13G>A [rs397515893]), cosegregating with the phenotype.Background The coronavirus disease 2019 (COVID-19) pandemic has raised several issues regarding the management of surgical patients. The aim of the current study was to clarify the management of oncologic and surgical patients during the pandemic. Methods Relevant publications reporting on the epidemiology of the pandemic, the diagnosis of the severe acute respiratory syndrome coronavirus 2 infection, and the clinical management of cancer and surgical patients, as well as studies concerning health care workers' safety, were included. The last date of research for this study was April 4, 2020. Results We analyzed 28 papers. Real-time polymerase chain reaction was considered the gold standard for the diagnosis of COVID-19, and computed tomography scans were considered useful for cases of diagnostic uncertainty. Cancer patients and surgical patients were confirmed to be particularly at risk of infection and negative outcome. To guarantee adequate care to these patients, while minimizing the risk for infection, the early postponing of elective surgery, the creation of COVID-free facilities and the identification of COVID- dedicated operating theaters and teams have been proposed. The correct use of personal protective equipment was also strongly advocated, along with the institution of facilities for the psychologic support of health care workers. Conclusion Clinicians should be aware of the importance of providing adequate care to patients with urgent and nondeferrable clinical issues, such as cancer. Every effort should be made to contain the virus spread in the hospital setting. Also, clinicians should value the importance of self-protection and mental health care.Background This a priori statistical analysis plan describes the methods of analysis for the Trial Of Prevention Strategies for low back pain (TOPS). Objectives TOPS aimed to investigate the effectiveness and cost-effectiveness of exercise and education classes compared with a minimal intervention control in preventing recurrence of low back pain (LBP) in people who have recently recovered from an episode of LBP. Methods TOPS is a superiority, pragmatic, parallel-group randomized controlled trial with allocation concealment, blinded outcome assessors, and intention-to-treat analysis. Participants were randomized to a physical therapist-led exercise and education program for 12 weeks or minimal intervention. The primary outcome was days to recurrence of an episode of LBP. The three key secondary outcomes were days to recurrence of an episode of LBP resulting in (1) activity limitation, (2) care seeking for LBP; and (3) work absence of at least 1 day. Differences in survival curves for the primary (days to recurrence) and secondary outcome (days to LBP with activity limitation, days to care seeking due to LBP, and days to work absence due to LBP) will be compared using Cox regression. Hazard ratios (HRs) and median survival times with 95% confidence intervals (CI) will be calculated. The number of adverse events, including serious adverse events will be reported and the proportion of adverse events between groups will be compared using a Chi-squared test. Discussion This paper will provide a detailed description of the planned analyses for the TOPS trial. Trial registration Australian New Zealand Clinical Trials Registry (ACTRN12615000939594).Objective To investigate clinical and dopaminergic pre-synaptic brain imaging characteristics of subjects with idiopathic rapid eye movement (REM) behavior disorder (iRBD) and mild cognitive impairment (MCI), and to evaluate the combined predictive value of risk factors for short-term conversion to synucleinopathy. Method In sum, 44 polysomnography (PSG)-confirmed iRBD patients (68.5 ± 7.2 years; 38 males) underwent 123I-FP-CIT-SPECT, comprehensive neuropsychological evaluation, clinical examination and clinical follow-up every six months (30.6 ± 21.5 months). Step-wise logistic regression was applied to identify those features discriminating iRBD patients with (iRBD-MCI; n = 14) and without MCI (normal cognition [NC], iRBD-NC; n = 30). The risk of neurodegeneration was estimated with Kaplan-Meier analysis. Predictors of phenoconversion were assessed with Cox proportional-hazards analysis, adjusting for age, gender and education. A generalized linear model (GLM) was applied to define the best combination of rgnosis.Background There is growing evidence to support an association between placental inflammation and neurological sequelae of preterm infants. The goal of this study is to evaluate the relationship between placental pathology, post-natal Doppler cerebral resistive indices (RI's), and intraventricular hemorrhage (IVH) in premature infants. Methods In a retrospective cohort study, preterm infants born between 23 0/7 and 32 6/7 weeks' gestation at Parkland Hospital were examined with placental pathology and serial ultrasound Doppler to evaluate for the primary outcome of IVH and death. Results A total of 255 infants were included, and 166 (65%) had at least one significant placental pathology, most commonly chorioamnionitis. Infants with placental pathologies were significantly more likely to have mothers with clinical chorioamnionitis and to have lower gestational ages. There was no observed association between placental pathology and IVH or death. Secondary analysis demonstrated that resistive indices obtained from the first and second head ultrasounds were not different in infants with IVH. Conclusion In this study, we observed a high rate of placental pathologies but no alterations in cerebral indices on ultrasound, or differences in rates of IVH or death. Additional studies are necessary to delineate the relationship between placental pathology, white matter brain injury, and outcomes.Although many review studies have been conducted on the physical benefits of water-based exercise, review studies on its psychological benefits are scarce. Thus, the aim of this integrative review was to explore the psychological effects of water-based exercise in older adults. Studies were included if they examined the psychological effects of water-based exercise in individuals aged 60 or older. The initial database search yielded 3861 studies. Duplicates and irrelevant studies were excluded by assessing titles and abstracts. Two additional studies were identified through ancestry searches. A total of 18 studies met the criteria. This review's findings suggest that water-based exercise can effectively improve individuals' quality of life, mood, depression, anxiety, tension, and fall efficacy. In addition, findings show that water-based exercise is feasible for both healthy older adults and those with chronic disease.Dysferlinopathies are a non-lethal group of late-onset muscular dystrophies. Here, we evaluated the fusion ability of primary myoblasts from young dysf-/- mice and the muscle histopathology prior to, and during early stages of disease onset. The ability of primary myoblasts of 5-week-old dysf-/- mice to form large myotubes was delayed compared to their wild-type counterparts, as evaluated by scanning electron microscopy. However, their fusion activity, as reflected by the presence of actin filaments connecting several cells, was enhanced by the antifibrotic drug halofuginone. Early dystrophic signs were already apparent in 4-week-old dysf-/- mice; their collagen level was double that in wild-type mice and continued to rise until 5 months of age. Continuous treatment with halofuginone from 4 weeks to 5 months of age reduced muscle fibrosis in a phosphorylated-Smad3 inhibition-related manner. Halofuginone also enhanced myofiber hypertrophy, reduced the percentage of centrally nucleated myofibers, and increased muscle performance. Together, the data suggest an inhibitory effect of halofuginone on the muscle histopathology at very early stages of dysferlinopathy, and enhancement of muscle performance. These results offer new opportunities for early pharmaceutical treatment in dysferlinopathies with favorable outcomes at later stages of life.Background Percutaneous balloon pulmonary valvuloplasty (PBPV) is the procedure of choice for uncomplicated severe or symptomatic pulmonary stenosis. Echocardiography (echo)-guided PBPV can completely avoid the use of radiation and contrast agents compared to fluoroscopy-guided PBPV. Although we have confirmed that echo-guided PBPV is feasible in humans, the poor visibility of the traditional catheter under echo greatly limits the promotion of this new technology. Methods We produced a novel double-balloon catheter to make the catheter easy to be detected by echo through adding a guiding balloon at the distal end of the catheter. Echo-guided PBPV was performed on thirty healthy swine using either a novel catheter or a traditional catheter to evaluate the feasibility and safety of the novel double-balloon catheter. The feasibility was evaluated by the success rate of balloon inflation at the pulmonary valve annulus and the operating time. The safety was evaluated by the frequency of balloon slippage and the incidence of complications. Results There were no significant between-group differences in terms of weight and the ratio of balloon diameter to pulmonary annulus diameter. The success rate was 93.3% and 60% in the novel and traditional groups, respectively. The novel group had significantly (p less then 0.05) lower mean procedure time (6.33±6.86min vs 24.8±9.79min) and lower frequency of balloon slippage (0.07±0.26 vs 0.53±0.52), arrhythmia (0.07±0.26 vs 0.47±0.52), and tricuspid regurgitation (6.7% vs 40%) than the traditional group. No myocardial hematoma or pericardial tamponade occurred in the novel catheter group. Conclusion Although further studies and improvements are required, the study results indicate that the novel double-balloon catheter for echo-guided PBPV is feasible and safe.Background Reflex testing is necessary to achieve the objectives of hepatitis C elimination. However, in 2017 only 31% of Spanish hospitals performed reflex test. As a consequence of that finding, reflex testing was recommended by scientific societies involved in the diagnosis and treatment of hepatitis C. Objective To evaluate the degree of implementation of reflex testing in 2019 and to know the implementation of rapid diagnostic and/or dried blood spot testing (RDT and / or DBS) in Spanish hospitals. Methods Cross-sectional study through a survey conducted in October 2019 to Spanish general hospitals with at least 200 beds, public or private with teaching accreditation. Results 129 (80%) hospitals responded. Reflex testing is performed by 89% of the centers vs. 31% in 2017 (P less then .001). From 2017 to 2019, centers using alerts to improve continuity of care increased from 69% to 86% (P=.002). selleck chemicals In 2019, 11% of centers can determine anti-HCV in dried spot, 15% viremia in dried spot, 0.85% anti-HCV in saliva, and 37% of antibodies and/or viremia with point of care test.
