Prediction of mortality in adult emergency department patients with sepsis

Abstract: Objectives: To determine the efficacy of the abbreviated Mortality in Emergency Department Sepsis (MEDS) score, the Modified Early Warning (MEW) score and near-patient-test (NPT) lactate levels in predicting 28-day mortality in adult emergency department (ED) patients with sepsis. Methods: A retrospective cohort study of adult ED patients with sepsis admitted to hospital was conducted in a large urban teaching and a district general hospital. Data were collected during four time periods between 1 January 2006 and 31 January 2007. Inclusion criteria were age ⩾16 years and an ED diagnosis of sepsis. Primary outcome for all patients was 28-day mortality. Patients were preassigned to risk groups according to their abbreviated MEDS score, MEW score and NPT lactate. Results: 307 ED patients with sepsis were included in the study. Among these there were 72 deaths (23%). Mortality rates for the low-, moderate- and high-risk groups of the abbreviated MEDS score were 1/63 (1.6%), 48/205 (23.4%) and 23/39 (59.0%) patients. The MEDS score for low-risk patients was 98.6% (95% CI 92.5% to 99.9%) sensitive and 26.5% (95% CI 21.0% to 32.6%) specific and for high-risk patients it was 31.9% (95% CI 21.4% to 44.0%) sensitive and 93.2% (95% CI 89.2% to 96.1%) specific for death within 28 days. Mortality rates for the low- and high-risk MEW score were 20/159 (12.6%) and 52/148 (35.1%) patients. The MEW score for high-risk patients was 72.2% (95% CI 60.4% to 82.1%) sensitive and 59.2% (95% CI 52.6% to 65.5%) specific for mortality. An NPT lactate level of ⩾4 mmol/l was 49.1% (95% CI 35.1% to 63.2%) sensitive and 74.3% (95% CI 64.8% to 82.3%) specific for 28-day mortality. Conclusion: These results demonstrate the efficacy of the abbreviated MEDS score, the MEW score and NPT venous lactate levels in predicting 28-day mortality in ED patients with sepsis. The abbreviated MEDS score was found to be the best performing risk assessment model which, with prospective validation, may aid early clinical decision-making in ED patients with sepsis and might affect the outcome from sepsis.

Psychological and psychosexual aspects of vulvar vestibulitis.

Abstract: AIMS: To objectively assess the psychological and psychosexual morbidity of patients with vulvar vestibulitis. METHODS: 30 patients with variable degrees of vulvar vestibulitis were recruited from a vulval clinic. Each patient underwent a detailed history and clinical examination. Friedrich's criteria were used for the diagnosis of vulvar vestibulitis. Standardised questionnaires to assess psychological and psychosexual function were completed by the patient before review. These questionnaires were the STAI and a modified psychosexual questionnaire introduced by Campion. RESULTS: Patients experienced considerable psychological dysfunction compared with controls. All aspects of psychosexual dysfunction were affected. CONCLUSIONS: When managing patients, psychosexual and psychological issues must be considered in addition to other conventional types of therapy. Vulvar vestibulitis may be a risk factor for developing psychosexual complications including vaginismus, low libido, and orgasmic dysfunction. Consideration of these factors must be an integral part of the management of patients with all chronic vulval conditions.

The evidence base for circulating tumour DNA blood-based biomarkers for the early detection of cancer: a systematic mapping review

Abstract: The presence of circulating cell-free DNA from tumours in blood (ctDNA) is of major importance to those interested in early cancer detection, as well as to those wishing to monitor tumour progression or diagnose the presence of activating mutations to guide treatment. In 2014, the UK Early Cancer Detection Consortium undertook a systematic mapping review of the literature to identify blood-based biomarkers with potential for the development of a non-invasive blood test for cancer screening, and which identified this as a major area of interest. This review builds on the mapping review to expand the ctDNA dataset to examine the best options for the detection of multiple cancer types. The original mapping review was based on comprehensive searches of the electronic databases Medline, Embase, CINAHL, the Cochrane library, and Biosis to obtain relevant literature on blood-based biomarkers for cancer detection in humans (PROSPERO no. CRD42014010827). The abstracts for each paper were reviewed to determine whether validation data were reported, and then examined in full. Publications concentrating on monitoring of disease burden or mutations were excluded. The search identified 94 ctDNA studies meeting the criteria for review. All but 5 studies examined one cancer type, with breast, colorectal and lung cancers representing 60% of studies. The size and design of the studies varied widely. Controls were included in 77% of publications. The largest study included 640 patients, but the median study size was 65 cases and 35 controls, and the bulk of studies (71%) included less than 100 patients. Studies either estimated cfDNA levels non-specifically or tested for cancer-specific mutations or methylation changes (the majority using PCR-based methods). We have systematically reviewed ctDNA blood biomarkers for the early detection of cancer. Pre-analytical, analytical, and post-analytical considerations were identified which need to be addressed before such biomarkers enter clinical practice. The value of small studies with no comparison between methods, or even the inclusion of controls is highly questionable, and larger validation studies will be required before such methods can be considered for early cancer detection.

Dog-bite lacerations: a controlled trial of primary wound closure.

Abstract: Dog-bite wounds are often left open because of their reputation for infection if primarily closed. A prospective randomized trial comparing primary closure with leaving the wound open was performed to assess infection and cosmesis. Ninety-six patients with 169 lacerations had thorough surgical debridement and irrigation of their wounds. Ninety-two wounds were sutured and 77 left open. No prophylactic antibiotics were given. A total of 13 wounds developed infection: seven sutured and six unsutured wounds (not statistically significant), giving an overall infection rate of 7.7%. Significantly (P less than 0.01), more wound infections occurred in the hand in both groups compared to the rest of the body, indicating that particular attention should be paid to management of such wounds. It was concluded that dog-bite wounds should receive thorough surgical treatment and can be safely sutured at presentation. Special care should be given to hand wounds.
