Cost per case or total cost? The potential of prevention of hand injuries in young children – Retrospective and prospective studies

<p>Abstract</p> <p>Background</p> <p>Health-care costs for hand and forearm injuries in young children are poorly documented. We examined costs in 533 children injured years 1996–2003.</p> <p>Methods</p> <p>Health-care costs and costs for lost productivity were retrospectively calculated in children from three catchment areas in Sweden. Seven case categories corresponding to alternative prevention strategies were constructed.</p> <p>Results</p> <p>Over time, diminishing number of ward days reduced the health-care cost per case. Among children, the cost of lost productivity due to parental leave was 14 percent of total cost. Fingertip injuries had low median costs but high total costs due to their frequency. Complex injuries by machine or rifle had high costs per case, and despite a low number of cases, total cost was high. Type of injury, surgery and physiotherapy sessions were associated with variations in health-care cost. Low age and ethnic background had a significant effect on number of ward days.</p> <p>Conclusion</p> <p>The costs per hand injury for children were lower compared to adults due to both lower health-care costs and to the fact that parents had comparatively short periods of absence from work. Frequent simple fingertip injuries and rare complex injuries induce high costs for society. Such costs should be related to costs for prevention of these injuries.</p

Multilayered Analyses of the Experiences of Undocumented Latinx College Students

Being the target of constant discrimination and marginalization can often cause intense negative psychological reactions and shame for undocumented students. The following qualitative study describes past and current undocumented Latinx students’ experiences of educational inequality in higher education influenced by labels associated with “being undocumented.” In this study we used a constructivist theoretical perspective which enabled us to focus on undocumented participants’ perspectives, experiences, meaning-making processes, values, and beliefs. Data was collected through hour-long, semi-structured interviews with five undocumented students. Student narratives were analyzed using a multi-layered analysis approach: (1) narrative, (2) thematic, and (3) critical incident analysis. Findings for this study provided insight on the narratives of carrying labels, themes associated with various labels, and critical incidents in the narratives and lives of undocumented students. Through our findings, we are able to contribute to existing literature and provide directions for future research

Renal cell carcinoma metastasis to the ciliary body responds to proton beam radiotherapy: a case report

<p>Abstract</p> <p>Introduction</p> <p>We report an unexpected presentation of metastatic renal cell carcinoma (RCC) to the ciliary body and an interesting response to proton beam radiotherapy.</p> <p>Case presentation</p> <p>We encountered a case of angle-closure glaucoma as the initial presentation of ocular metastasis to the ciliary body in a 65-year-old Caucasian man who had undergone right radical nephrectomy for RCC 15 years earlier. He underwent YAG (yttrium aluminium garnet) laser peripheral iridotomy while further metastatic workup took place. His condition was eventually diagnosed as stage IV metastatic RCC of the clear cell type and involved multiple sites, including the ciliary body, brain, lungs, liver, and pancreas. The progression of RCC metastasis to the ciliary body was studied for 16 months. The ciliary body mass continued to grow despite systemic treatment with temsirolimus and interleukin-2 and intravitreal injections of bevacizumab. The tumor size peaked at 6.11 × 6.06 mm before the start of proton therapy, which reduced the tumor size to 5.07 × 4.39 mm.</p> <p>Conclusions</p> <p>RCC can produce metastases involving unusual sites many years after resection of the primary tumor. Proton therapy was found to be effective in treating RCC metastasis to the ciliary body in settings in which other treatment modalities failed.</p

Use of venous-thrombotic-embolic prophylaxis in patients undergoing surgery for renal tumors: a questionnaire survey in the Nordic countries (The NORENCA-2 study)

Purpose: To examine the variation in venous thromboembolism prophylactic treatment (VTEP) among renal cancer patients undergoing surgery. Materials and methods: An Internet-based questionnaire on renal tumor management before and after surgery was mailed to all Nordic departments of urology. The questions focused on the use of VTEP and were subdivided into different surgical modalities. Results: Questionnaires were mailed to 91 institutions (response rate 53%). None of the centers used VTEP before surgery, unless the patient had a vena caval tumor thrombus. Overall, the VTEP utilized during hospitalization for patients undergoing renal surgery included early mobilization (45%), compression stockings (52%) and low-molecular-weight heparin (89%). In patients undergoing open radical Nx, 80% of institutions used VTEP during their hospitalization (23% compression stockings and 94% low-molecular-weight heparin). After leaving the hospital, the proportion and type of VTEP received varied considerably across institutions. The most common interval, used in 60% of the institutions, was for a period of 4 weeks. The restriction to the Nordic countries was a limitation and, therefore, may not reflect the practice patterns elsewhere. It is a survey study and, therefore, cannot measure the behaviors of those institutions that did not participate. Conclusion: We found variation in the type and duration of VTEP use for each type of local intervention for renal cancer. These widely disparate variations in care strongly argue for the establishment of national and international guidelines regarding VTEP in renal surgery.Peer reviewe

Sea temperature effects on depth use and habitat selection in a marine fish community

Understanding the responses of aquatic animals to temperature variability is essential to predict impacts of future climate change and to inform conservation and management. Most ectotherms such as fish are expected to adjust their behaviour to avoid extreme temperatures and minimize acute changes in body temperature. In coastal Skagerrak, Norway, sea surface temperature (SST) ranges seasonally from 0 to over 20°C, representing a challenge to the fish community which includes cold-, cool- and warm-water affinity species.publishedVersio

In vivo editing of the pan-endothelium by immunity evading simian adenoviral vector

Biological applications deriving from the clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 site-specific nuclease system continue to impact and accelerate gene therapy strategies. Safe and effective in vivo co-delivery of the CRISPR/Cas9 system to target somatic cells is essential in the clinical therapeutic context. Both non-viral and viral vector systems have been applied for this delivery matter. Despite elegant proof-of-principle studies, available vector technologies still face challenges that restrict the application of CRISPR/Cas9-facilitated gene therapy. Of note, the mandated co-delivery of the gene-editing components must be accomplished in the potential presence of pre-formed anti-vector immunity. Additionally, methods must be sought to limit the potential of off-target editing. To this end, we have exploited the molecular promiscuities of adenovirus (Ad) to address the key requirements of CRISPR/Cas9-facilitated gene therapy. In this regard, we have endeavored capsid engineering of a simian (chimpanzee) adenovirus isolate 36 (SAd36) to achieve targeted modifications of vector tropism. The SAd36 vector with the myeloid cell-binding peptide (MBP) incorporated in the capsid has allowed selective in vivo modifications of the vascular endothelium. Importantly, vascular endothelium can serve as an effective non-hepatic cellular source of deficient serum factors relevant to several inherited genetic disorders. In addition to allowing for re-directed tropism, capsid engineering of nonhuman primate Ads provide the means to circumvent pre-formed vector immunity. Herein we have generated a SAd36. MBP vector that can serve as a single intravenously administered agent allowing effective and selective in vivo editing for endothelial target cells of the mouse spleen, brain and kidney.

Integrated next-generation sequencing of 16S rDNA and metaproteomics differentiate the healthy urine microbiome from asymptomatic bacteriuria in neuropathic bladder associated with spinal cord injury

Background Clinical dogma is that healthy urine is sterile and the presence of bacteria with an inflammatory response is indicative of urinary tract infection (UTI). Asymptomatic bacteriuria (ABU) represents the state in which bacteria are present but the inflammatory response is negligible. Differentiating ABU from UTI is diagnostically challenging, but critical because overtreatment of ABU can perpetuate antimicrobial resistance while undertreatment of UTI can result in increased morbidity and mortality. In this study, we describe key characteristics of the healthy and ABU urine microbiomes utilizing 16S rRNA gene (16S rDNA) sequencing and metaproteomics, with the future goal of utilizing this information to personalize the treatment of UTI based on key individual characteristics. Methods A cross-sectional study of 26 healthy controls and 27 healthy subjects at risk for ABU due to spinal cord injury-related neuropathic bladder (NB) was conducted. Of the 27 subjects with NB, 8 voided normally, 8 utilized intermittent catheterization, and 11 utilized indwelling Foley urethral catheterization for bladder drainage. Urine was obtained by clean catch in voiders, or directly from the catheter in subjects utilizing catheters. Urinalysis, urine culture and 16S rDNA sequencing were performed on all samples, with metaproteomic analysis performed on a subsample. Results A total of 589454 quality-filtered 16S rDNA sequence reads were processed through a NextGen 16S rDNA analysis pipeline. Urine microbiomes differ by normal bladder function vs. NB, gender, type of bladder catheter utilized, and duration of NB. The top ten bacterial taxa showing the most relative abundance and change among samples were Lactobacillales, Enterobacteriales, Actinomycetales, Bacillales, Clostridiales, Bacteroidales, Burkholderiales, Pseudomonadales, Bifidobacteriales and Coriobacteriales. Metaproteomics confirmed the 16S rDNA results, and functional human protein-pathogen interactions were noted in subjects where host defenses were initiated. Conclusions Counter to clinical belief, healthy urine is not sterile. The healthy urine microbiome is characterized by a preponderance of Lactobacillales in women and Corynebacterium in men. The presence and duration of NB and method of urinary catheterization alter the healthy urine microbiome. An integrated approach of 16S rDNA sequencing with metaproteomics improves our understanding of healthy urine and facilitates a more personalized approach to prevention and treatment of infection
