Impact of timing of presentation of acute pancreatitis to a tertiary care centre on the outcome

Background and objectives

Despite improvement in outcomes of acute pancreatitis (AP), some subgroups remain at increased risk. We studied the impact of onset-to-admission interval to a tertiary care centre on outcomes in AP.

Critical congenital heart disease screening does not predict car seat tolerance screen outcomes

BackgroundCar Seat Tolerance Screening (CSTS) and Critical Congenital Heart Disease (CCHD) screens were both implemented to identify infants with cardiorespiratory distress. We hypothesized that the CCHD screen would be poorly sensitive to predict a failed CSTS for many reasons.MethodsRetrospective record review of infants in 2013 who qualified for CSTS. Calculated sensitivity, specificity, predictive value (PV) of a failed CCHD screen to identify those infants who failed their CSTS.Results270 subjects underwent both screens and 14 failed a CSTS (5.2%). Of these, 1 failed the CCHD and 1 had an equivocal result. None were diagnosed with CCHD. An abnormal CCHD (failed or equivocal) had a sensitivity = 14.3% and a PV = 40% for predicting CSTS failure.ConclusionsCCHD screening is poorly sensitive and has poor PV for identifying those infants who are at risk of failing a CSTS. We therefore cannot recommend replacement of the CSTS with routine CCHD screening.     

New legal requirements for submission of product information to poisons centres in EU member states

Introduction: In the past eight years, the European Association of Poisons Centres and Clinical Toxicologists (EAPCCT) has been intensively involved in a European Commission led process to develop EU legislation on the information of hazardous products that companies have to notify to EU Poisons Centres (or equivalent “appointed bodies”). As a result of this process, the Commission adopted Regulation (EU) No 2017/542, amending the CLP Regulation by adding an Annex on harmonised product submission requirements.

Harmonised mixture information requirements: Detailed and consistent information on the composition of the hazardous product will become available to EU Poisons Centres (PC). The information will be submitted by companies to PCs (or equivalent “appointed bodies”) using a web-based software application or in-house software. Two new important features are introduced. Firstly, to be able to rapidly identify the product formula, a Unique Formula Identifier (UFI) on the product label links to the submitted information. Secondly, for better comparability of reports on poisonings between EU member states, a harmonised Product Categorisation System will specify the intended use of a product. Rapid product identification and availability of detailed composition information will lead to timely and adequate medical intervention. This may lead to considerable reduction in healthcare costs.

Additionally, for companies trading across the EU, costs of submission of this information will be reduced significantly.

Next steps: From 2017, an implementation period has started, consisting of a three-year period for stakeholders to implement the new requirements, followed by a gradual applicability for consumer products (2020), professional products (2021) and industrial use-only products (2024). Technical tools to generate the electronic format and the UFI together with guidance documents are expected to be made available by the end of 2017 by the European Chemicals Agency (ECHA). Guidance on interpretation of legal text and ECHA helpdesk support are planned to be ready at the end of 2018.     

A Before and After Analysis of Health Care Utilization by Patients Enrolled in Opioid Controlled Substance Agreements for Chronic Noncancer Pain

Objective

To evaluate the impact of opioid controlled substance agreements (CSAs) enrollment on health care utilization.

Toxicological aspects of trans fat consumption over two sequential generations of rats: Oxidative damage and preference for amphetamine

Chronic consumption of processed food causes structural changes in membrane phospholipids, affecting brain neurotransmission. Here we evaluated noxious influences of dietary fats over two generations of rats on amphetamine (AMPH)-conditioned place preference (CPP). Female rats received soybean oil (SO, rich in n-6 fatty acids (FA)), fish oil (FO, rich in n-3 FA) and hydrogenated vegetable fat (HVF, rich in trans fatty acids (TFA)) for two successive generations. Male pups from the 2nd generation were maintained on the same supplementation until 41 days of age, when they were conditioned with AMPH in CPP. While the FO group showed higher incorporation of n-3 polyunsaturated-FA (PUFA) in cortex/hippocampus, the HVF group showed TFA incorporation in these same brain areas. The SO and HVF groups showed AMPH-preference and anxiety-like symptoms during abstinence. Higher levels of protein carbonyl (PC) and lower levels of non-protein thiols (NPSH) were observed in cortex/hippocampus of the HVF group, indicating antioxidant defense system impairment. In contrast, the FO group showed no drug-preference and lower PC levels in cortex. Cortical PC was positively correlated with n-6/n-3 PUFA ratio, locomotion and anxiety-like behavior, and hippocampal PC was positively correlated with AMPH-preference, reinforcing connections between oxidative damage and AMPH-induced preference/abstinence behaviors. As brain incorporation of trans and n-6 PUFA modifies its physiological functions, it may facilitate drug addiction.     

Germinal center B (GCB) and non-GCB cell-like diffuse large B cell lymphomas have similar outcomes following autologous haematopoietic stem cell transplantation

Patients with germinal center B cell-like (GCB) and non-GCB diffuse large B cell lymphomas (DLBCL) receiving first line therapy have distinct prognosis. We explored the differences in outcome following salvage autologous hematopoietic stem cell (HSC) transplantation between patients with GCB and non-GCB DLBCL. Forty-four patients with relapsed and 15 patients with primary refractory chemosensitive disease undergoing BEAM (BCNU [carmustine], etoposide, cytarabine, melphalan) conditioning and autologous HSC were included. Immunohistochemical analysis was performed for CD10, BCL-6, MUM1 (allowing classification into GCB and non-GCB-like DLBCL) and BCL-2. Median follow-up of survivors was 25 months; median age at the time of transplantation was 60 years (range 17–77). Thirty-two patients (54%) were classified as having GCB and 27 (46%) as having non-GCB-like DLBCL. Patients with GCB and non-GCB DLBCL did not differ in the risk of progression after HSC transplant ( P  = 0·78) or overall survival ( P  = 0·48). In multivariate analysis, only time to progression after initial treatment impacted overall survival. We conclude that patients with relapsed or primary refractory chemosensitive GCB and non-GCB-like DLBCL derive similar benefit from autologous HSC transplant.     

Impact of covid-19 pandemic on characteristics of dental emergencies and treatment services at tertiary care centre

PurposeTo categorize and compare the dental emergencies along with status of health services received in the tertiary dental health care centre during the pre covid- 19 periods and period of the complete lockdown in COVID 19 pandemic. Methods: A retrospective cross-sectional observational survey was conducted. Four different groups period were studied on patients who visited for dental emergencies at tertiary care centre. April 14 to 13 May 2020 assigned and analyzed as a test period group or group IV. The control period group i.e. group III was 14 February 2020 to 17 March, pre lockdown COVID 19 month when there was no consideration of epidemic in India. Same as periods of group II and IV, group I and II from last year 2019 were also assigned and analyzed. The tertiary care centre provision of health services during this pandemic was also inquired and evaluated. The information was recorded regarding availability of health services like non-emergency dental treatments, emergency dental services, and online professional consultation. To compare four different time period of obtained data, Analysis of variance (ANOVA) and Chi square test were used. Results: The overall proportion and percentage of dental emergencies were raised. The reason for emergency visits to dental clinic were the main problem related with pulpal (46.0%) followed by abscess (16.6%), periapical lesions (15.0%), cellulitis (4.1%) or trauma (0.3%). In lockdown most of the dental emergencies 228(2 6 5) were endodontic related (86.1%) which managed mostly through ‘3A” approach (advise, analgesics and antibiotics) (60.1%) and remaining (26.0%) through extraction.
