Medical device-related complications often lead to emergency department (ED) visits and hospitalizations for children with medical complexity (CMC), and pediatric complex care programs may be one way to decrease unnecessary encounters.

A retrospective cohort study comparing ED and inpatient encounters due to device complications of 2 cohorts of CMC at a single children's hospital during 2014-2016; 99 enrolled in a complex care program and 244 in a propensity-matched comparison group. Structured chart reviews identified ED and inpatient encounters due to device complications. The outcome was a change in the frequency of these encounters from the year before to the year after enrollment in the hospital's complex care program. Program effects were estimated with weighted difference-in-differences (DiDs), comparing the change in mean encounter frequency for CMC enrolled in the program with change for propensity-matched children not enrolled in the program.

Mean encounters related to device complications decreased for both groups. Complication-related ED encounters per year decreased from a weighted mean (SD) of 0.74 (0.85) to 0.30 (0.44) in enrolled children and 0.26 (0.89) to 0.12 (0.56) in comparison children, a DiD of 0.30 fewer [95% confidence interval (CI) -0.01 to 0.60]. The largest reductions in device complication ED visits were among those with enteral tubes [0.36 fewer (95% CI 0.04-0.68)]. Hospitalizations decreased over time, but DiDs were not significantly different between groups.

Acute care use from device complications decreased with time. Complex care program enrollment may be associated with more substantial reductions in device complication ED visits, and effects may be most pronounced for CMC with enteral tubes.

Previous observational studies have reported an association between lumbosacral radiculopathy (LSR), a form of low back pain (LBP) with nerve root involvement, and constipation. However, it is unclear whether this association is due to confounding variables such as comorbidities and medications.

This study explores the possible association between LSR and constipation, with the hypothesis that adults with LSR have increased odds of developing constipation compared with those with nonradicular LBP.

Adults aged 18 to 49 years with incident LSR and nonradicular LBP were identified from a national 70 million patient electronic health records network (TriNetX). Propensity score matching (PSM) was used to control for covariates and determine the odds ratio (OR) of constipation over a 1-year follow-up. Lumbar stenosis, cauda equina syndrome, and inflammatory bowel diseases were excluded.

After PSM, 503,062 patients were in each cohort. Before PSM, the likelihood of constipation was identical between cohorts , such as pain severity, physical inactivity, and constipating medications.Chronic pelvic pain (CPP) is a highly prevalent condition which is underdiagnosed and poorly understood. The purpose of this review is to outline the various aspects of the nature of CPP, including its etiologies, clinical presentation, and nonoperative treatment options. For data collection, a PubMed search was conducted using indexing terms such as chronic pelvic pain and pelvic pain. Literature reviews and studies focusing on etiologies, clinical presentation, and/or the diagnosis of CPP were compiled for review by a team of 3 physiatrists. Studies investigating conservative treatments, medications, and interventional procedures for CPP and related conditions with comparable etiologies were also included. Of the 502 articles retrieved, 116 were deemed suitable by the team for this study. Although CPP is a complex, multifaceted condition, a particular susceptibility to nociceptive stimuli was demonstrated as an underlying theme in its evolution. There are many treatment options currently used; however, more robust evidence, such as randomized controlled trials, are needed before creating comprehensive guidelines for treating CPP.

Elderspeak is an inappropriate simplified speech register that sounds like baby talk and is used with older adults, especially in health care settings. Understanding the concept of elderspeak is challenging due to varying views about which communicative components constitute elderspeak and whether elderspeak is beneficial or harmful for older adults.

Rodgers' evolutionary concept analysis method was used to evaluate the concept of elderspeak through identification of elderspeak's attributes, antecedents, and consequences. A systematic search using the PubMed, CINAHL, PsycINFO, and Embase databases was completed.

Eighty-three theoretical or research articles from 1981 to 2020 were identified. Elderspeak characteristics were categorized by semantic, syntactic, pragmatic, paralinguistic, and nonverbal attributes. The primary antecedent to elderspeak is implicit ageism, in which old age cues and signs of functional or cognitive impairment led to simplified communication, usually from a younger caregiver. Reiated from those that do not. Recommendations for consistent operationalization of elderspeak in future research are made.Singlet fission is a carrier multiplication mechanism that could make silicon solar cells much more efficient. The singlet-fission process splits one high-energy spin-singlet exciton into two lower-energy spin-triplet excitons. We calculated the efficiency potential of three technologically relevant singlet-fission silicon solar cell implementations. We assume realistic but optimistic parameters for the singlet-fission material and investigate the effect of singlet energy and entropic gain. If the transfer of triplet excitons occurs via charge transfer, the maximum efficiency is 34.6% at a surprisingly small singlet energy of 1.85 eV. For the Dexter-type triplet energy transfer, the maximum efficiency is 32.9% at a singlet energy of 2.15 eV. For Förster resonance energy transfer (FRET), the triplet excitons are first transferred into a quantum dot, from which they then undergo FRET into silicon. For this transfer mechanism, the maximum efficiency is 28.% at a singlet energy of 2.33 eV. We show that the efficiency gain from singlet fission is larger the more efficient the silicon base cell is, which stands in contrast to tandem perovskite-silicon solar cells.

Inherited peripheral neuropathies (IPNs) are a group of genetic disorders of the peripheral nervous system in which neuropathy is the only or the most predominant clinical feature. The most common type of IPN is Charcot-Marie-Tooth (CMT) disease. Autosomal recessive CMT (ARCMT) is generally more severe than dominant CMT and its genetic basis is poorly understood due to high clinical and genetic diversity. Here, we report clinical and genetic findings from 56 consanguineous Turkish families initially diagnosed with CMT disease.

We initially screened the

gene in our cohort as it is the most commonly mutated ARCMT gene. Next, whole-exome sequencing and homozygosity mapping based on whole-exome sequencing (HOMWES) analysis was performed. To understand the molecular impact of candidate causative genes, functional analyses were performed in patient primary fibroblasts.

Biallelic recurrent mutations in the

gene have been identified in 6 patients. Whole-exome sequencing and HOMWES analysis revealed 16 recurrent and 13 novel disease-causing alleles in known IPN-related genes and 2 novel candidate genes 1 for a CMT-like disease and 1 for autosomal recessive cerebellar ataxia with axonal neuropathy. We have achieved a potential genetic diagnosis rate of 62.5% (35/56 families) in our cohort. Considering only the variants that meet the American College for Medical Genetics and Genomics (ACMG) classification as pathogenic or likely pathogenic, the definitive diagnosis rate was 55.35% (31/56 families).

This study paints a genetic landscape of the Turkish ARCMT population and reports additional candidate genes that might help enlighten the mechanism of pathogenesis of the disease.

There are currently no reports describing outcomes after multiorgan transplantation with DCD livers. The use of DCD organs for multiorgan transplantation can be enhanced if the detrimental effects of prolonged cold ischemia and subsequent ischemia-reperfusion injury are overcome. We present a case in which the liver and lungs of a DCD donor were preserved using ex situ machine perfusion for combined liver-lung transplantation. The recipient was a 19-year-old male patient requiring bilateral lung transplantation for severe progressive pleural parenchymal fibroelastosis and portal hypertension with portal vein thrombosis. The donor liver was preserved with dual hypothermic oxygenated machine perfusion, whereas the lungs were perfused using ex vivo lung perfusion. With ex vivo lung perfusion, total preservation time of right and left lung reached 17 and 21 h, respectively. Now, 2 y after transplantation, liver function is normal and lung function is improving. To conclude, we suggest that combined transplantation of DCD liver and lungs is feasible when cold ischemia is reduced with ex situ machine perfusion preservation.

Cholesterol embolization syndrome (CES) is an uncommon but well-known cause of renal failure in native kidneys, but little is known about CES in kidney transplant recipients. The aim of this study was to determine the incidence, clinical characteristics, histopathology, and prognosis of CES after kidney transplantation.

CES cases in both transplanted and native kidneys (control group) were identified by searching the databases of the divisions of Nephrology and Pathology of our institution. Suberoylanilide hydroxamic acid Clinical data were retrospectively collected. Biopsies were classified according to the latest Banff 2019 Update. Second, a systematic literature search was performed (December 01, 2020) of Ovid MEDLINE, EMBASE, the Cochrane Central Register of controlled trials, Google Scholar, and Web of Science.

CES was observed in for-cause biopsies of 11 out of 2350 (0.47%) kidney transplant recipients transplanted between January 1, 2006, and December 31, 2018 (0.0009 cases per person-year). All patients had ≥1 cardiovascular rf kidney transplant failure, although the incidence of CES may be underestimated. CES may mimic rejection as it can be accompanied by arteritis.

Delayed graft function (DGF) affects over 25% of deceased donor kidney transplants (DDKTs) and is associated with increased cost, worsened graft outcomes, and mortality. While approaches to preventing DGF have focused on minimizing cold ischemia, donor factors such as acute tubular injury can influence risk. There are currently no pharmacologic therapies to modify DGF risk or promote repair, in part due to our incomplete understanding of the biology of preimplantation tubular injury.

We collected intraoperative, preimplantation kidney biopsies from 11 high-risk deceased donors and 10 living donors and followed transplant recipients for graft function. We performed quantitative high-dimensional histopathologic analysis using imaging mass cytometry to determine the cellular signatures that distinguished deceased and living donor biopsies as well as deceased donor biopsies which either did or did not progress to DGF.

We noted decreased tubular cells (

 < 0.0001) and increased macrophage infiltration (
