Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study
Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P < 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P < 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk
Species identification of adult African blowflies (Diptera: Calliphoridae) of forensic importance:
Necrophagous blowflies can provide an excellent source of evidence for forensic entomologists and are also relevant to problems in public health, medicine, and animal health. However, access to useful information about these blowflies is constrained by the need to correctly identify the flies, and the poor availability of reliable, accessible identification tools is a serious obstacle to the development of forensic entomology in the majority of African countries. In response to this need, a high-quality key to the adults of all species of forensically relevant blowflies of Africa has been prepared, drawing on high-quality entomological materials and modern focus-stacking photomicroscopy. This new key can be easily applied by investigators inexperienced in the taxonomy of blowflies and is made available through a highly accessible online platform. Problematic diagnostic characters used in previous keys are discussed

Marine Tar Residues: a Review
Abstract Marine tar residues originate from natural and anthropogenic oil releases into the ocean environment and are formed after liquid petroleum is transformed by weathering, sedimentation, and other processes. Tar balls, tar mats, and tar patties are common examples of marine tar residues and can range in size from millimeters in diameter (tar balls) to several meters in length and width (tar mats). These residues can remain in the ocean envi-ronment indefinitely, decomposing or becoming buried in the sea floor. However, in many cases, they are transported ashore via currents and waves where they pose a concern to coastal recreation activities, the seafood industry and may have negative effects on wildlife. This review summarizes the current state of knowledge on marine tar residue formation, transport, degradation, and distribution. Methods of detection and removal of marine tar residues and their possible ecological effects are discussed, in addition to topics of marine tar research that warrant further investigation. Emphasis is placed on ben-thic tar residues, with a focus on the remnants of the Deepwater Horizon oil spill in particular, which are still affecting the northern Gulf of Mexico shores years after the leaking submarine well was capped
Do "In-Clinic" Molecular and Non-Molecular Rapid Tests Improve Patient Management?
Background Excluding HIV testing, point-of-care tests (POCTs) for STIs are not routinely available in UK sexual health clinics, apart from microscopy which has limited sensitivity, is observer dependent and often only allows for imprecise syndromic treatment. From sample-to-result for routine Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) molecular tests usually takes several days. Molecular and non-molecular STI-POCTs, including automated urine flow cytometry, may improve patient pathways, obviate the need for microscopy and personalise treatment effectively. Methods This was a clinic evaluation using a rapid molecular test for CT/NG (Cepheid GeneXpert; 90 minute turnaround) combined with non-molecular POCTs for Trichomonas vaginalis (OSOM), Bacterial vaginosis (Alere VS-Sense) and automated urinary white cell count (WCC) for urethritis (Alere UF-100). Contacts of CT/NG, males with symptoms of urethritis, and symptomatic females provided samples immediately on arrival, prior to clinical consultation. Patients also concurrently had routine culture and microscopy. View this table:Abstract P2.163 Table 1 ResultsOf eighteen patients providing feedback, all but one found providing samples on arrival acceptable; waiting < 2 hours was acceptable to all, but waiting > 2 hours was seen as too long. All patients waited for the results of their non-molecular POCT but only three of nineteen men waited for the rapid GeneXpert results, despite six being positive. All positive patients were given appropriate empirical treatment. A third of women waited despite all being GeneXpert negative. The TV and BV POCTs detected more cases than microscopy, and urethral smear detected more urethritis than automated WCC. Conclusion Despite the provision of genital samples on arrival being acceptable and patients liking the idea of receiving results in the same clinical visit, only a quarter of all patients waited for their GeneXpert results. Larger studies to evaluate the clinical impact of rapid molecular testing in clinic are required before any large scale implementation is considered
