OBJECTIVE Peer support is important for psychosocial well-being in patients with rheumatoid arthritis (RA). Our objective was to assess the interactions, engagement, and perceptions of participants in an online support group for patients with RA. METHODS Participants were 18 years or older, diagnosed with RA within 10 years, and residing in the USA or Canada. All participated in a closed Facebook online support group. Membership was by invitation only, and discussions were visible only to members, moderators, and two research staff. Each week, participants discussed a topic posted by a moderator. They also shared other disease-relevant information beside the topics posted. We assessed participants' engagement and qualitatively analyzed the content of their postings in the first 5 weeks of participation. RESULTS The group had 90 participants 94% were female and 83% white. Median age was 54 (24-84) years. Mean number of contributors per week was 50 (range, 42-62); 10% of participants never contributed to the dito pay special attention to how to ensure a sustained participant interest in online social support group among patients with rheumatoid arthritis.PURPOSE To compare renal sinus fat volume (RSFV) separately within the right and left kidneys between bilateral nephrolithiasis patients and healthy controls. METHODS This cross-sectional study analyzed patients who underwent unenhanced abdominal computed tomography (CT) divided into nephrolithiasis (n = 102) and healthy control (n = 130) groups. Age, sex, blood pressure [systolic blood pressure (SBP) and diastolic blood pressure (DBP)], estimated glomerular filtration rate (eGFR), body weight, and height of each participant were extracted. Volumetric renal sinus adipose tissue was measured separately for both kidneys on CT images. Urea, serum creatinine (Scr), uric acid (UA), total serum cholesterol (TCH), serum triglyceride (TG), and serum high- and low-density lipoprotein (HDL and LDL, respectively) cholesterol levels were obtained. RESULTS Overall, 232 participants (mean age 47 years, 50% women) were enrolled. There were no differences in sex, DBP, urea, and LDL-cholesterol between the two groups (all p > 0.05). However, nephrolithiasis patients had higher age, BMI, SBP, and RSFV; higher Scr, UA, TCH, and TG serum levels; and lower HDL-cholesterol level and eGFR. check details Average left RSFV was significantly higher than right RSFV in healthy controls (4.56 ± 2.29 versus 3.34 ± 1.90 cm3, p  less then  0.001). A significant relationship between bilateral RSFV, age, BMI, SBP, and eGFR was noted in bilateral nephrolithiasis patients. Multivariate linear regression analysis showed age, BMI, and LDL-cholesterol to be independent predictors of left RSFV, and only BMI was an independent predictor of right RSFV. CONCLUSIONS Our data showed renal sinus adipose tissue accumulation and the relationship among RSFV, age, BMI, and LDL-cholesterol in bilateral nephrolithiasis patients.Biofilm in endoscopes is a major problem that can result in failure of disinfection. We studied the survival of K. pneumoniae in a biofilm formed on endoscope tubes subjected to combined chemical and physical stresses. We monitored bacterial survival in the biofilm after the action of 1% and 2% GTA either immediately or after 15 days of desiccation and described the ability of surviving bacteria to recolonize endoscope tubing in a dynamic model. There were surviving bacteria after 5-min exposure to 2% and 1% GTA. link2 The percentage of survivors after 2% and 1% GTA was greater when the GTA treatment was performed after 15 days of prior desiccation of the biofilm. The survivors were able to recolonize and reform biofilm on abiotic surfaces probably because of the survival of persisters in a viable but non-culturable state in the biofilm. Our findings emphasize that the current guidelines on endoscope reprocessing should be strictly followed but that once constituted the biofilm in endoscope tubing will be very difficult to eradicate with present practices.Urogenital schistosomiasis (UGS) remains common in sub-Saharan African migrants. The aim of the study was to describe UGS cases detected among patients attending primary healthcare consultations in free outpatient clinics in Paris. This retrospective cohort study included all cases of active UGS from 2004 to 2017. Cases were defined by the presence of Schistosoma haematobium typical ova at urine microscopy. Primary care physicians prescribed it on the basis of epidemiological or clinical criteria. Demographic, clinical, biological, and imaging data were retrieved. Active UGS was diagnosed in 105 cases. The sex ratio (F/M) was 3/102 with a median age of 25. Most cases came from West Africa and recently arrived in Europe (median delay, 1 year). Patients under 18 (23%) were more frequent after 2011. Compatible symptoms were reported in 63/104 patients (60%), hematuria being the most frequent (43/104). link3 Urine dipstick detected micro-hematuria in 42/60 patients screened (70%). In 73 cases, urine microscopy was performed from either one, two, or three micturitions on separate days. The rate of positive urine microscopy increased from one (69.2%) to two micturitions (95.4%). All patients except three received praziquantel. Among those who underwent ultrasonography, 30/86 (35%) had abnormalities, 28/30 at the bladder. A step-by-step clinical assessment led to the detection of active UGS questions on age, location in childhood and hematuria, physical examination, and urine dipstick. A prospective study in primary care is needed for protocol-based management of active UGS to be part of a socio-medical program for migrants.Achaete-scute complex (ASC) genes play essential roles in regulating neurogenesis of metazoans. Various metazoan species have greatly different numbers of genes in ASCa, ASCb and ASCc families. To explore evolutionary mechanisms of metazoan ASC genes, Blast (basic local alignment search tool) searches and phylogenetic analyses were conducted to identify ASC genes in metazoan species and to infer phylogenetic relationship between various ASC genes. As a result, 2784 ASC genes were identified in 804 metazoan species. The phylogenetic tree constructed using 1237 unique bHLH motifs shows that metazoan ASCa, ASCb and ASCc families contain six (a1-a6), five (b1-b5) and three (c1-c3) bHLH genes, respectively. Further phylogenetic analyses suggest that ASC genes in metazoans are derived from a primitive c gene, those in insects are derived from c2 gene, and those in chordates are derived from a2 and a3 genes. Data of gene linkage demonstrate that insect a6 is derived from a4 but not from a5, and chordate a2 is ancestral to b5 only, whilst a3 is ancestral to both b3 and b5. It is concluded that current ASC gene families in metazoans were established through a series of sub- and/or neo-functionalization to duplicated ancestral ASC gene(s). These results provide good references for exploring evolutionary mechanisms of other bHLH genes in metazoans. Besides, gene subtyping is considered as an efficient method for evolutionary studies on closely related homologous genes.PURPOSE Acute/uncomplicated cystitis is the most common bacterial infection causing inflammation in the bladder tissues and predominantly diagnosed in women. Interstitial cystitis may too, cause inflammation in the bladder but its etiology has been elusive. Even though the site and symptoms of both diseases are largely shared, state of the urinary microbiome in these disorders have not been comparatively evaluated before. The purpose of this review is to assess and qualitatively compare structure and composition of the urinary microbiome in acute/uncomplicated cystitis and interstitial cystitis. METHODS AND RESULTS The available literature in MEDLINE are extensively searched using keywords and screened. Pertinent evidence is carefully assessed and synthesized. We included the original studies with a cohort of medically stable, non-pregnant women with otherwise functionally normal urinary tract and excluded the original articles if the infection in a patient's cohort is accompanied by urinary syndromes such as incontinence and overactive bladder syndrome. A total of six original papers reporting on the urinary microbiome in acute cystitis and nine papers on the interstitial cystitis met the selection criteria. CONCLUSION The evidence we have gleaned from the literature on the urinary microbiome associated with the acute and interstitial cystitis does not point to convergence of microbiome similarities between the two diseases. More studies with direct sampling of the bladder tissues besides sampling bladder surfaces are warranted for accurate comparison of microbiome similarity between the two conditions. The future research on interstitial cystitis microbiome should include stratified cohorts with prospective design.OBJECTIVES To develop a dual-modal neural network model to characterize ultrasound (US) images of breast masses. MATERIALS AND METHODS A combined US B-mode and color Doppler neural network model was developed to classify US images of the breast. Three datasets with breast masses were originally detected and interpreted by 20 experienced radiologists according to Breast Imaging-Reporting and Data System (BI-RADS) lexicon ((1) training set, 103212 masses from 45,433 + 12,519 patients. (2) held-out validation set, 2748 masses from 1197 + 395 patients. (3) test set, 605 masses from 337 + 78 patients). The neural network was first trained on training set. Then, the trained model was tested on a held-out validation set to evaluate agreement on BI-RADS category between the model and the radiologists. In addition, the model and a reader study of 10 radiologists were applied to the test set with biopsy-proven results. To evaluate the performance of the model in benign or malignant classifications, the receiver operatiologist and has the potential to automate the routine characterization of breast masses.OBJECTIVE Assess the sensitivity and specificity of computed tomography angiography (CTA) for carotid near-occlusion diagnosis interpreted in clinical practice against expert assessment. METHODS CTAs were graded by two expert interpreters for near-occlusion. Findings were compared with clinical reports in 383 consecutive cases with symptomatic ≥ 50% carotid stenosis. In addition, 14 selected CTA exams (8 near-occlusions and 6 controls) were analyzed in a national effort by 13 radiologists experienced with carotid CTA. RESULTS In clinical practice, imaging reports were 20% (95% CI 12-28%) sensitive for near-occlusion, ranging 0-58% between different radiologists; specificity was 99%. Among the 13 radiologists reviewing the same 8 near-occlusions, the average sensitivity was 8%, ranging 0-75%; specificity was 100%. CONCLUSIONS Carotid near-occlusion is systematically under-reported in clinical routine practice, caused by limited application of grading criteria when assessing CTA. KEY POINTS • Carotid near-occlusion is severe stenosis with distal artery collapse; this collapse is often subtle. • A fifth of near-occlusions were detected in routine practice. Many readers mistake near-occlusion for stenosis without distal artery collapse, either by not actively searching for subtle collapses or by not interpreting the collapse correctly when noticed. • On the other hand, the novice diagnostician should be cautioned to not over-diagnose near-occlusion; other causes of extracranial ICA asymmetry also exist such as distal disease and Circle of Willis anatomical variants.
