Lyme Disease Prevention in Western Connecticut

Lyme disease is a bacterial infection that is endemic to the Northeastern region of the United States, specifically Connecticut. Spread by the deer tick, Lyme can produce a constellation of symptoms that can adversely impact an individual. Living in Connecticut transfers a significant amount of risk to individuals and understanding the appropriate prevention techniques should afford protection from deer tick bites. Having a robust resource on preventative measures and signs and symptoms of Lyme will provide a foundation for minimizing the risk of getting Lyme disease.https://scholarworks.uvm.edu/fmclerk/1423/thumbnail.jp

Impact of Deferral for Low Hemoglobin on Donor Return

Introduction. A consistent blood supply to support life-saving transfusions relies on regular and repeat volunteer blood donations. In this study, we focused on donors previously deferred for low-hemoglobin (Hb) levels to better understand the value of supplying post-deferral educational information, and the actions donors took based on their deferral. Methods. An anonymous national survey of active and inactive donor groups (10,000 each) was conducted. The survey questions assessed post-deferral donor actions, preferences regarding post deferral education, understanding of their deferral, and demographic information. Chi-square analysis was performed to compare categorical survey results between donor groups with p \u3c 0.05 denoting statistical significance. Results. The survey resulted in 722 and 103 active and inactive donor respons- es, respectively. Active donors were more likely to recall receiving educational materials post-deferral (52% vs. 35%, p=003), take iron and vitamin supplements (54% vs. 39%, p=0.009), lived within 30 min of a donor site (94% vs. 84%, p=0.006), and more likely to be older than 45 yr (62% vs. 42%, p=0.002) than their inactive donor counter- parts. Active and inactive donors were similar (p\u3e0.05) with anemia history frequency, female-gender predominance, low-prevalence of vegans, and mixed interest in receiving information about raising hemoglobin levels. Conclusion. While active donors more frequently recalled receiving educational materials for their low hemoglobin deferral, and were more likely to take action to improve their hemoglobin, an alternative method of post-deferral recruitment should be considered given the uncertain value of post-deferral information when comparing active vs. inactive donors.https://scholarworks.uvm.edu/comphp_gallery/1253/thumbnail.jp

Pooled analysis of WHO Surgical Safety Checklist use and mortality after emergency laparotomy

Background The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89.6 per cent) compared with that in countries with a middle (753 of 1242, 60.6 per cent; odds ratio (OR) 0.17, 95 per cent c.i. 0.14 to 0.21, P <0001) or low (363 of 860, 422 per cent; OR 008, 007 to 010, P <0.001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference -94 (95 per cent c.i. -11.9 to -6.9) per cent; P <0001), but the relationship was reversed in low-HDI countries (+121 (+7.0 to +173) per cent; P <0001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0.60, 0.50 to 073; P <0.001). The greatest absolute benefit was seen for emergency surgery in low- and middle-HDI countries. Conclusion Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries.Peer reviewe

Global variation in anastomosis and end colostomy formation following left-sided colorectal resection

Background End colostomy rates following colorectal resection vary across institutions in high-income settings, being influenced by patient, disease, surgeon and system factors. This study aimed to assess global variation in end colostomy rates after left-sided colorectal resection. Methods This study comprised an analysis of GlobalSurg-1 and -2 international, prospective, observational cohort studies (2014, 2016), including consecutive adult patients undergoing elective or emergency left-sided colorectal resection within discrete 2-week windows. Countries were grouped into high-, middle- and low-income tertiles according to the United Nations Human Development Index (HDI). Factors associated with colostomy formation versus primary anastomosis were explored using a multilevel, multivariable logistic regression model. Results In total, 1635 patients from 242 hospitals in 57 countries undergoing left-sided colorectal resection were included: 113 (6·9 per cent) from low-HDI, 254 (15·5 per cent) from middle-HDI and 1268 (77·6 per cent) from high-HDI countries. There was a higher proportion of patients with perforated disease (57·5, 40·9 and 35·4 per cent; P < 0·001) and subsequent use of end colostomy (52·2, 24·8 and 18·9 per cent; P < 0·001) in low- compared with middle- and high-HDI settings. The association with colostomy use in low-HDI settings persisted (odds ratio (OR) 3·20, 95 per cent c.i. 1·35 to 7·57; P = 0·008) after risk adjustment for malignant disease (OR 2·34, 1·65 to 3·32; P < 0·001), emergency surgery (OR 4·08, 2·73 to 6·10; P < 0·001), time to operation at least 48 h (OR 1·99, 1·28 to 3·09; P = 0·002) and disease perforation (OR 4·00, 2·81 to 5·69; P < 0·001). Conclusion Global differences existed in the proportion of patients receiving end stomas after left-sided colorectal resection based on income, which went beyond case mix alone

CODA - A Mobile Application for Medical Discharge

CODA is a mobile application which is designed to assist with medical discharge by changing the way users organize the information their medical information. Hospital discharge is not just the moment a patient leaves the hospital, but also the patient\u27s efforts to manage their conditions outside of the hospital as well as provider\u27s efforts to prepare for discharge while a patient is in the hospital. Poor discharge can lead to readmission to the hospital, increased health care costs and other poor outcomes. In this presentation the features of CODA will be detailed along with current and futures efforts

PTPN22 inhibition resets defective human central B cell tolerance

The 1858T protein tyrosine phosphatase nonreceptor type 22 (PTPN22 T) allele is one of the main risk factors associated with many autoimmune diseases and correlates with a defective removal of developing autoreactive B cells in humans. To determine whether inhibiting PTPN22 favors the elimination of autoreactive B cells, we first demonstrated that the PTPN22 T allele interfered with the establishment of central B cell tolerance using NOD-scid-common γ chain knockout (NSG) mice engrafted with human hematopoietic stem cells expressing this allele. In contrast, the inhibition of either PTPN22 enzymatic activity or its expression by RNA interference restored defective central B cell tolerance in this model. Thus, PTPN22 blockade may represent a therapeutic strategy for the prevention or treatment of autoimmunity

Activation-Induced Cytidine Deaminase Expression in Human B Cell Precursors Is Essential for Central B Cell Tolerance

SummaryActivation-induced cytidine deaminase (AID), the enzyme-mediating class-switch recombination (CSR) and somatic hypermutation (SHM) of immunoglobulin genes, is essential for the removal of developing autoreactive B cells. How AID mediates central B cell tolerance remains unknown. We report that AID enzymes were produced in a discrete population of immature B cells that expressed recombination-activating gene 2 (RAG2), suggesting that they undergo secondary recombination to edit autoreactive antibodies. However, most AID+ immature B cells lacked anti-apoptotic MCL-1 and were deleted by apoptosis. AID inhibition using lentiviral-encoded short hairpin (sh)RNA in B cells developing in humanized mice resulted in a failure to remove autoreactive clones. Hence, B cell intrinsic AID expression mediates central B cell tolerance potentially through its RAG-coupled genotoxic activity in self-reactive immature B cells
