Monitoring brain oxygenation and intracranial pressure non-invasively and continuously is of paramount importance in traumatic brain injury (TBI). The primary motivation of this study was to identify and provide robust evidence of the most effective techniques for the non-invasive multimodal monitoring for traumatic brain injury. Two reviewers independently searched PubMed, Embase, Scopus, the Cochrane Library, and the Web of Science between January 15, 2010, and January 22, 2020. Cohort studies assessing correlation or accuracy of non-invasive techniques for intracranial pressure (ICP) and/or brain oxygenation monitoring in TBI patients were included. The Newcastle-Ottawa Scale was used to assess the methodological quality of the studies. PROSPERO registration ID is CRD42020164739. Eight out of the 12 studies selected focused on the non-invasive measurement of ICP. Near-Infrared spectroscopy was the main technology for brain oxygenation, whereas ultrasound-based techniques were also used for ICP monitoring. PbtO2 monitoring through near-infrared spectroscopy showed low correlation and limited accuracy in detecting hypoxic events. A meta-analysis on non-invasive ICP monitoring revealed a strong pooled correlation coefficient of 0.725 (95 % confidence interval [CI] 0.450-0.874; I2 91.31%) between transcranial Doppler and the gold standard ICP monitoring. The current meta-analysis has shown that the two most prominent and widely used technologies for non-invasive monitoring in TBI are near-infrared spectroscopy and transcranial Doppler. Both techniques could be considered for the future development of a single non-invasive and continuous multimodal monitoring device for TBI.
CaMKII (Ca
-Calmodulin dependent protein kinase) δC activation is implicated in pathological progression of heart failure (HF) and CaMKIIδC transgenic mice rapidly develop HF and arrhythmias. However, little is known about early spatio-temporal Ca
handling and CaMKII activation in hypertrophy and HF.
To measure time- and location-dependent activation of CaMKIIδC signaling in adult ventricular cardiomyocytes, during transaortic constriction (TAC) and in CaMKIIδC transgenic mice.
We used human tissue from nonfailing and HF hearts, 4 mouse lines wild-type, KO (CaMKIIδ-knockout), CaMKIIδC transgenic in wild-type (TG), or KO background, and wild-type mice exposed to TAC. Confocal imaging and biochemistry revealed disproportional CaMKIIδC activation and accumulation in nuclear and perinuclear versus cytosolic regions at 5 days post-TAC. This CaMKIIδ activation caused a compensatory increase in sarcoplasmic reticulum Ca
content, Ca
transient amplitude, and [Ca
] decline rates, with reduced phospholambat chronic progression of this nuclear Ca
-CaMKIIδC axis contributes to eccentric hypertrophy and HF.
We conclude that in early TAC perinuclear CaMKIIδC activation promotes adaptive increases in myocyte Ca2+ transients and nuclear transcriptional responses but that chronic progression of this nuclear Ca2+-CaMKIIδC axis contributes to eccentric hypertrophy and HF.
Research ethics review committees (RERCs) and Human Research Protection Programs (HRPPs) are responsible for protecting the rights and welfare of research participants while avoiding unnecessary inhibition of valuable research. Evaluating RERC/HRPP quality is vital to determining whether they are achieving these goals effectively and efficiently, as well as what adjustments might be necessary. Various tools, standards, and accreditation mechanisms have been developed in the United States and internationally to measure and promote RERC/HRPP quality.
We systematically reviewed 10 quality assessment instruments, examining their overall approaches, factors considered relevant to quality, how they compare to each other, and what they leave out. For each tool, we counted the number of times each of 34 topics (divided into structure, process, and outcome categories) was mentioned. We generated lists of which topics are most and least mentioned for each tool, which are most prevalent across tools, and which are lERC/HRPP quality assessment instruments largely rely on surrogate measures of participant protection. To prioritize between these measures and preserve limited resources for evaluating the most important criteria, we recommend that instruments focus on elements relevant to participant outcomes, robust board deliberation, and procedures most likely to address participant risks. Validation of these approaches remains an essential next step.Paper-based works of art and documents of cultural importance kept in museums and libraries can show notorious signs of deterioration, including foxing stains, caused by fungal colonization. PKR-IN-C16 mw Some of the main chromophore agents of fungal origin that deteriorate paper and therefore affect paper cultural heritage both aesthetically and structurally are the group of pigments called melanins. Thus, knowledge of the diversity and features of fungal melanins and of the melanization pathways of fungi growing on paper is key to removing these pigments from paper-based works of cultural importance. This review provides an approach about the current knowledge of melanins synthesized by paper-colonizing fungi, their localization in the fungal structures, and their role in the deterioration of paper. This knowledge might contribute to developing new, effective, and sustainable strategies of restoration and conservation of historical documents and works of art based on paper.This article examines the relationship between sexual satisfaction and gender, age, social status, being in stable relationships, intercourse frequency, and satisfaction with physical attractiveness (physical appearance and sex appeal). A self-report questionnaire was applied in a representative sample of 767 residents of Santiago (Chile), over 18 years old and that have had, at least, one sexual relation (with penetration) during their lives. Higher sexual satisfaction was predicted negatively by age and positively by higher satisfaction with sex appeal, higher intercourse frequency and having a stable relationship. Among women, the principal predictors are satisfaction with sex appeal and intercourse frequency. Among men to the above, it is necessary to add satisfaction with physical appearance and having a stable relationship - at odds with supposed higher relevance for women of body satisfaction and sensibility to social relationships. Discussion emphasizes the controversial nature of the gender differences found regarding the Latin American culture.The reconstruction of large-volume soft tissue defects is a major problem in plastic surgery. Many plastic surgeons have focused on external volume expansion (EVE) because of its capacity to promote regeneration of soft tissues, including breast, subcutaneous fat, and skin. EVE is a minimally invasive and less costly tissue engineering approach that has shown great clinical potential. However, many challenges still need to be addressed before such technology can become a common clinical practice. Basic in vivo and in vitro studies have been performed to determine the possible mechanisms by which EVE promotes tissue regeneration and to design optimized animal models. EVE application was found to facilitate cell proliferation and migration, enhance adipogenesis, improve angiogenesis, and provide available space for soft tissue growth. Understanding the mechanical and chemical signals associated with EVE during tissue regeneration may enable the clinical adaptation of this technology. This article reviews the clinical application of EVE techniques, describes preclinical animal models, and evaluates the possible mechanisms by which EVE induces tissue regeneration.

Tourette syndrome (TS) is characterised by the presence of sudden, rapid movements and vocalizations (tics). The nature of tics suggests impairments in inhibitory control. However, findings of impaired inhibitory control have so far been inconsistent, possibly due to small sample sizes, wide age ranges, or not taking medication use or attention-deficit/hyperactivity disorder (ADHD) comorbidity into account.
We investigated group differences in response inhibition using an fMRI-based stop-signal task in 103 8 to 12-year-old children (
 = 51 with TS, of whom
 = 28 without comorbid ADHD [TS - ADHD] and
 = 23 with comorbid ADHD [TS + ADHD]; and
 = 52 healthy controls), and related these measures to tic and ADHD severity.
We observed an impaired response inhibition performance in children with TS + ADHD, but not in those with TS - ADHD, relative to healthy controls, as evidenced by a slower stop-signal reaction time, slower mean reaction times, and larger variability of reaction times. Dimensional analyses implicated ADHD severity as the driving force in these findings. Neural activation during failed inhibition was stronger in the inferior frontal gyrus and temporal and parietal areas in TS + ADHD compared to healthy controls.
Impaired inhibitory performance and increased neural activity in TS appear to manifest predominantly in relation to ADHD symptomatology.

This multi-center observational trial included brain-injured adults presenting to the ED, receiving a head computed tomography (CT) and venipuncture for biomarker concentration measurements within 6 h of injury. Subjects had repeat serum sampling and GCS scores every 4 h for the first 24 h, if available for assessment. We analyzed blood samples using an enzyme-linked immunosorbent assay approved by the Food and Drug Administration (FDA). Wilcoxin two-sample test was used to compare initial and repeat serum concentrations for both biomarkers between CT-positive patients who did not have an acute unfavorable neurological outcome and thop = 0.041.Hospitals have increasingly relied on nurse assistants to support nurses in the provision of patient care, yet knowledge about their contributions to the patient experience in U.S. hospitals is limited. We address this issue by exploring the impact of nurse assistants and registered nurses on an array of patient satisfaction measures from the Medicare Hospital Consumer Assessment of Healthcare Providers and Systems. Using linked data for 2,807 hospitals from 2008 to 2016, we employ a production function approach to estimate and plot marginal impact curves for both nurse assistants and registered nurses. We find that although registered nurses are more impactful, nurse assistants are the more underdeployed staffing category. We also find that after meeting certain thresholds for minimal hours, nurse assistants have a comparative advantage in improving patient satisfaction scores in the housekeeping and patient support domain. Given their lower labor costs, further employment of nurse assistants may be warranted.
