There are various models attempting to predict 30-day readmissions of acutely admitted internal medicine patients. However, it is uncertain how to create a parsimonious index that has equivalent predictive ability and can be extrapolated to other settings.
 
  We developed a regression equation to predict 30-day readmissions from all acute hospitalizations in internal medicine departments in a regional hospital in 2015-2016 and validated the model in 2019. The independent (predictor) variables were age, past hospitalizations, admission laboratory test results, length of stay in hospital and discharge diagnoses. We compared the predictive value of a logistic regression model and index that included discharge diagnoses and admission laboratory test results with one that included only age, past hospitalizations, and hospital length of stay.
 
  Readmission rates were associated with age, time since last hospitalization, number of previous hospitalizations, and length of stay, as well as with a diagnosis of chronicferentiated between the risks of readmission within 30 days without the need for discharge diagnosis and laboratory variables.
  The intraglomerular mesangial cells are located between the glomerular capillaries. Here we hypothesized that mesangial cells regulate the single nephron glomerular filtration rate (snGFR) and that mesangial cells support the integrity of the glomerular filtration barrier.
 
  We assessed the function of mesangial cells in vivo by multiphoton microscopy. Mesangial cells were depleted in Munich Wistar Froemter rats using the Thy1.1 antibody model.
 
  The Thy1.1 antibody caused the cell-specific loss of 82±3% of mesangial cells. After mesangial cell depletion, the baseline snGFR was reduced to 12.0±1.2 vs 32.4±3.2nL/min in controls. In control rats, the snGFR decreased after angiotensin II infusion by 61±3% (P=.004), whereas it remained unchanged in Thy1.1-treated rats. The changes in the snGFR after angiotensin II infusion in control rats were accompanied by the marked rotation of the capillary loops within Bowman's space. This phenomenon was absent in anti-Thy1.1-treated rats. The glomerular sieving coefficient (GSC
  ) for albumin, used as a measure of the integrity of the glomerular filtration barrier, was low in control rats (0.00061±0.00004) and increased after angiotensin II infusion (0.00121±0.00015). In Thy1.1-treated rats, the GSC was elevated (0.0032±0.00059) and did not change in response to angiotensin II. Electron microscopy revealed the increased thickness of the glomerular basement membrane after mesangial cell depletion.
 
  Our data suggest that mesangial cells actively contribute to the regulation of the snGFR. Furthermore, mesangial cells are crucially involved in maintaining the integrity of the glomerular filtration barrier, in part by modulating the thickness of the glomerular basement membrane.

  The basement membrane (BM) provides mechanical shaping of tissues during morphogenesis. The Drosophila BM proteoglycan Perlecan is vital for this process in the wing imaginal disc. This function is thought to be fostered by the heparan sulfate chains attached to the domain I of vertebrate Perlecan. However, this domain is not present in Drosophila, and the source of Perlecan for the wing imaginal disc BM remains unclear. Here, we tackle these two issues.
 
  In silico analysis shows that Drosophila Perlecan holds a domain I. Moreover, by combining in situ hybridization of Perlecan mRNA and protein staining, together with tissue-specific Perlecan depletion, we find that there is an autonomous and a non-autonomous source for Perlecan deposition in the wing imaginal disc BM. We further show that both sources cooperate for correct distribution of Perlecan in the wing imaginal disc and morphogenesis of this tissue.
 
  These results show that Perlecan is fully conserved in Drosophila, providing a valuable in vivo model system to study its role in BM function. The existence of two different sources for Perlecan incorporation in the wing imaginal disc BM raises the possibility that inter-organ communication mediated at the level of the BM is involved in organogenesis.

The type of care people with NSSI receive at the hospital impacts their health outcomes. This study explored emergency department (ED) and mental health nurses' (MHNs) understanding, attitudes, empathy and confidence to work with people presenting with NSSI. ED and MHNs who belonged to either the College of Emergency Nursing Australasia (CENA) or the Australian College of Mental Health Nurses (ACMHN) were invited to complete an online survey through a group email from their college. One hundred and one nurses (56 ED and 45 MHNs) completed the survey. The results revealed that nurses from both groups had an accurate understanding of NSSI and had positive attitudes about patients who self-injure. However, confidence was higher among MHNs. Greater knowledge of NSSI was correlated with increased confidence, positive attitudes and empathy. For mental health nurses, but not ED nurses, years of clinical practice was associated with nurses' confidence.  https://www.selleckchem.com/products/cc-930.html  In contrast, ED nurses with more than 10 years' experience were less confident in addressing NSSI than ED nurses with less experience. Issues that affect both ED and MHNs' knowledge, attitude, empathy and confidence to care for patients who self-injure are multifactorial. Future education and training should focus on therapeutic interactions with people at risk of repeat NSSI. Further, more research is recommended to explore patients' perspectives of nurses' attitudes in care for people who self-injure.
