Restoring cardiopulmonary circulation with effective chest compression remains the cornerstone of resuscitation, yet real-time compressions may be suboptimal. This project aims to determine whether in patients with in-hospital cardiac arrest (IHCA; population), chest compressions performed with free-standing audiovisual feedback (AVF) device as compared to standard manual chest compression (comparison) results in improved outcomes, including the sustained return of spontaneous circulation (ROSC), and survival to the intensive care unit (ICU) and hospital discharge (outcomes).
Scholarly databases and relevant bibliographies were searched, as were clinical trial registries and relevant conference proceedings to limit publication bias. Studies were not limited by date, language, or publication status. Clinical randomized controlled trials (RCT) were included that enrolled adults (age ≥ 18 years) with IHCA and assessed real-time chest compressions delivered with either the standard manual technique or with AVF from a freestanding device not linked to an automated external defibrillator (AED) or automated compressor.
Four clinical trials met inclusion criteria and were included. No ongoing trials were identified. One RCT assessed the Ambu CardioPump (Ambu Inc., Columbia, MD, USA), whereas three assessed Cardio First Angel™ (Inotech, Nubberg, Germany). No clinical RCTs compared AVF devices head-to-head. Three RCTs were multi-center. Sustained ROSC (4 studies,
= 1064) was improved with AVF use (Relative risk [RR] 1.68, 95% confidence interval [CI] 1.39-2.04), as was survival to hospital discharge (2 studies,
= 922; RR 1.78, 95% CI 1.54-2.06) and survival to hospital discharge (3 studies,
= 984; RR 1.91, 95% CI 1.62-2.25).
The moderate-quality evidence suggests that chest compressions performed using a non-AED free-standing AVF device during resuscitation for IHCA improves sustained ROSC and survival to ICU and hospital discharge.

PROSPERO (CRD42020157536).The present study aimed to determine the average concentration of some metals, including cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni) and lead (Pb) in the chicken, hen's liver, and gizzard in the east of Iran. Estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI) and carcinogenic risk (CR) were calculated. In this cross-sectional study, fifty one samples including chicken, hen's liver and gizzard were obtained from Birjand, Iran. Measurement of Cd, Cr, Cu, Ni, and Pb was carried out by using an Inductively Coupled Plasma-Optic Emission Spectroscopy (ICP-OES). All of the measured metals were detected in 100 % of the samples. The metals had a different distribution pattern. The highest concentration of Cd and Cu was in the liver samples while the Cr and Ni had the highest levels in the chicken. Pb concentration was at the highest level in the gizzard. The least amount of Cr, Ni, and Pb was found in the liver while Cu had the least content in the muscle. EDI had an acceptable level, but the highest daily intake of all studied metals was through muscle. Cr had the highest THQ and it was more than one in the meat. HI in chicken was more than one. Liver and gizzard of hens had a neglectable HI. CR was neglectable in the case of both Cd and Pb, but it was considerable for Cr and Ni. The consumption of chicken in both adults and children may pose a significant health risk for consumers.A 65-year-old woman visited our hospital complaining of dyspnea several days before admission. A chest X-ray showed massive right-sided pleural effusion, which was not observed 1 month previously. Although the patient had never been diagnosed with cirrhosis at regular visits, the patient was diagnosed with primary biliary cholangitis at admission. Hepatic hydrothorax was suspected because pleural effusion was transudative. A diaphragmatic fistula was confirmed and closed by thoracoscopy. Pleural effusion did not reappear after this procedure. Existence of a diaphragmatic defect should be confirmed under direct vision if pleural effusion accumulates acutely or becomes beyond control.Understanding spatial inhomogeneity and clustering in point patterns arises in many contexts, ranging from disease outbreak monitoring to analyzing radiologically-based emphysema in biomedical images. This can often involve classifying individual points as being part of a feature/cluster or as being part of a background noise process. Existing methods for this task can struggle when there are differences in the size and/or density of individual clusters. Selleckchem GLPG0187 In this work, we propose employing kernel density estimates of the underlying point process intensity function, using an existing data-driven approach to bandwidth selection, to separate feature points from noise. This is achieved by constructing a null distribution, either through asymptotic properties or Monte Carlo simulation, and comparing kernel density estimates to a given quantile of this distribution. We demonstrate that our method, termed Kernel Density and Simulation based Filtering (KDS-Filt), showed superior performance to existing alternative approaches, especially when there is inhomogeneity in cluster sizes and density. We also show the utility of KDS-Filt for identifying clinically relevant information about the spatial distribution of emphysema in lung computed tomography scans. The KDS-Filt methodology is available as part of the sncp R package, which can be downloaded at https//github.com/stop-pre16/sncp.
Flame retardant (FR) compounds can adversely impact neurodevelopment. This updated literature review summarizes epidemiological studies of FRs and neurotoxicity published since 2015, covering historical (polybrominated biphenyls [PBBs], polychlorinated biphenyls [PCBs]), contemporary (polybrominated diphenyl ethers [PBDEs], hexabromocyclododecane [HBCD], and tetrabromobisphenol A [TBBPA]), and current-use organophosphate FRs (OPFRs) and brominated FRs (2-ethylhexyl 2,3,4,5-tetrabromobezoate [EH-TBB] TBB), bis(2-ethylhexyl) tetrabromophthalate [BEH-TEBP]), focusing on prenatal and postnatal periods of exposure.
Continuing studies on PCBs still reveal adverse associations on child cognition and behavior. Recent studies indicate PBDEs are neurotoxic, particularly for gestational exposures with decreased cognition and increased externalizing behaviors. Findings were suggestive for PBDEs and other behavioral domains and neuroimaging. OPFR studies provide suggestive evidence of reduced cognition and more behavioral problems.
