These results imply that TK-CATH participates in both the inflammatory phase and new tissue formation phase of wound repair process. Meanwhile, TK-CATH exhibited weak but effective free radical scavenging activity and low cytotoxicity. All the results above indicate that TK-CATH is a multifunctional peptide in the skin of the salamander T. kweichowensis. It may play important roles in host immune responses against bacterial infection and skin wound repair.
Women have been historically under-represented in vascular surgery and cardiovascular medicine trials. The rate and change in representation of women in trials of common vascular diseases over the last decade is not understood completely.

We used publicly available data from ClinicalTrials.gov to evaluate trials pertaining to carotid artery stenosis (CAS), peripheral arterial disease (PAD), thoracic and abdominal aortic aneurysms (TAA and AAA), and type B aortic dissections (TBAD) from 2008 to the present. We evaluated representation of women in these trials based on the participation-to-prevalence ratios (PPR), which are calculated by dividing the percentage of women among trial participants by the percentage of women in the disease population. Panobinostat in vitro Values of 0.8 to 1.2 reflect similar representation.

The sex distribution was reported in all 97 trials, including 11 CAS trials, 68 PAD trials, 16 TAA/AAA trials, and 2 TBAD trials. The total number of participants in these trials was 41,622 and the median numb vascular diseases remains low and has not improved since 2008. Therefore, the generalizability of recent trial results to women with these vascular diseases remains unknown. An improved understanding of the underlying root causes for poor female trial participation, advocacy, and education are required to improve the generalizability of trial results for female vascular patients.
Approximately 15% of infants require stimulation in low-resource settings, but data on effectiveness of different stimulation approaches are limited. We aimed to compare two recommended approaches of stimulation (back rubs vs. foot flicks) in reducing the need for face-mask ventilation in newly born infants who were not crying immediately after birth in a low-resource setting.

A single center, open-label, randomized, superiority trial was conducted at St. Kizito Hospital in Matany (Uganda) between November 2019 and May 2020. Newly born infants with expected birthweight>1500 grams who were not crying immediately after birth were randomly assigned to stimulation using back rubs or foot flicks. The primary outcome measure was the success rate of the stimulation, defined as the achievement of an effective crying preventing the need for face-mask ventilation.

Success of stimulation was achieved in 76/93 neonates (82%) using back rubs and 68/93 neonates (73%) using foot flicks (risk ratio 1.12, 95% confidence interval 0.96-1.31). No procedure-associated complications arose during the study. Time to first cry was not statistically different between the two arms (mean difference -11 seconds, 95% confidence interval -39 to 18).

In newly born infants who were not crying immediately after birth, this trial did not provide a conclusive message in favor of back rubs or foot flicks. Nonetheless, we could not exclude a possible benefit of back rubs in avoiding the need for positive pressure ventilation and, possibly, further advanced resuscitative maneuvers.

Point-of-care ultrasound (POCUS) has been shown to assist in predicting outcomes in cardiac arrest. We evaluated the test characteristics of POCUS in predicting poor outcomes failure of return of spontaneous circulation (ROSC), survival to hospital admission (SHA), survival to hospital discharge (SHD) and neurologically intact survival to hospital discharge (NISHD) in adult and paediatric patients with blunt and penetrating traumatic cardiac arrest (TCA) in out-of-hospital or emergency department settings.

We conducted a systematic review and meta-analysis using the PRISMA guidelines. We searched Clinicaltrials.gov, CINAHL, Cochrane library, EMBASE, Medline and the World Health Organization-International Clinical Trials Registry from 1974 to November 9, 2020. Risk of bias was assessed using QUADAS-2 tool. We used a random-effects meta-analysis model with 95% confidence intervals with I
statistics for heterogeneity.

We included 8 studies involving 710 cases of TCA. For all blunt and penetrating TCA patients who failed to achieve ROSC, the specificity (proportion of patients with cardiac activity on POCUS who achieved ROSC) was 98% (95% CI 0.13 to 1.0). The sensitivity (proportion of patients with cardiac standstill on POCUS who failed to achieve ROSC) was 91% (95% CI 0.67 to 0.98). No patient with cardiac standstill survived. Substantial level of heterogeneity was noted.

Patients in TCA without cardiac activity on POCUS have a high likelihood of death and negligible chance of SHD. The numbers of patients included in published studies remains too low for practice recommendations for termination of resuscitation based solely upon the absence of cardiac activity on POCUS.

To describe burden and health-related quality of life amongst caregivers of out-of-hospital cardiac arrest survivors and explore the potential association with cognitive function of the survivors. Caregivers of patients with ST-elevation myocardial infarction were used as controls.

Data were collected from the cognitive substudy of the Targeted Temperature Management-trial. Caregiver burden was assessed with the 22-item Zarit Burden Interview, with scores ≤20 considered as no burden. Health-related quality of life was assessed with the SF-36v2®, with T-scores 47-53 representing the norm. Cardiac arrest survivors were categorized based on the results from cognitive assessments as having "no cognitive impairment" or "cognitive impairment".

Follow-up 6months post event was performed for caregivers of 272 cardiac arrest survivors and 108 matched myocardial infarction controls, included at an intended ratio of 21. In general, caregivers of cardiac arrest survivors and controls reported similar caregiver burden. The overall scores for quality of life were within normative levels and similar for caregivers of cardiac arrest survivors and control patients. Compared to those with no cognitive impairment, caregivers of cognitively impaired cardiac arrest survivors (n=126) reported higher levels of burden (median 18 versus 8, p<0.001) and worse quality of life in five of eight domains, particularly "Role-Emotional" (mean 45.7 versus 49.5, p=0.002).

In general, caregivers of cardiac arrest survivors and myocardial infarction controls reported similar levels of burden and quality of life. Cognitive outcome and functional dependency of the cardiac arrest survivor impact burden and quality of life of the caregiver.

We sought to develop a machine learning analytic (eCART Lite) for predicting clinical deterioration using only age, heart rate, and respiratory data, which can be pulled in real time from patient monitors and updated continuously without need for additional inputs or cumbersome electronic health record integrations.

We utilized a multicenter dataset of adult admissions from five hospitals. We trained a gradient boosted machine model using only current and 24-hour trended heart rate, respiratory rate, and patient age to predict the probability of intensive care unit (ICU) transfer, death, or the combined outcome of ICU transfer or death. The area under the receiver operating characteristic curve (AUC) was calculated in the validation cohort and compared to those for the Modified Early Warning Score (MEWS), National Early Warning Score (NEWS), and eCARTv2, a previously-described, 27-variable, cubic spline, logistic regression model without trends.

Of the 556,848 included admissions, 19,509 (3.5%) were transferred to an ICU and 5764 (1.0%) died within 24 hours of a ward observation. eCART Lite significantly outperformed the MEWS, NEWS, and eCART v2 for predicting ICU transfer (0.79 vs 0.71, 0.74, and 0.78, respectively; p<0.01) and the combined outcome (0.80 vs 0.72, 0.76, and 0.79, respectively; p<0.01). Two of the strongest predictors were respiratory rate and heart rate.

Using only three inputs, we developed a tool for predicting clinical deterioration that is similarly or more accurate than commonly-used algorithms, with potential for use in inpatient settings with limited resources or in scenarios where low-cost tools are needed.

Out of Hospital Cardiac arrest (OHCA) survivors with ST elevation (STE) with or without shockable rhythms often benefit from coronary angiography (CAG) and, if indicated, percutaneous coronary intervention (PCI). However, the benefits of CAG and PCI in OHCA survivors with nonshockable rhythms (PEA/asystole) and no STE are debated.

Using the International Cardiac Arrest Registry (INTCAR 2.0), representing 44 centers in the US and Europe, comatose OHCA survivors with known presenting rhythms and post resuscitation ECGs were identified. Survival to hospital discharge, neurological recovery on discharge, and impact of CAG with or without PCI on such outcome were assessed and compared with other groups (shockable rhythms with or without STE).

Total of 2113 OHCA survivors were identified and described as; nonshockable/no STE (Nsh-NST) (n=940, 44.5%), shockable/no STE (Sh-NST) (n=716, 33.9%), nonshockable/STE (Nsh-ST) (n=110, 5.2%), and shockable/STE (Sh-ST) (n=347, 16.4%). Of Nsh-NST, 13.7% (129) were previou with high prevalence of acute culprit coronary lesions and should be considered for those with a probably cardiac cause for their arres.As the most common cause of dementia, Alzheimer's disease (AD) is progressively neurodegenerative disease. In the initial stage, Alzheimer's disease is related to the memory disorder, followed by a serious progressive decline in cognitive function, and finally died. Neurofibrillary tangles (NFTs) deposited in neurons form one of the histopathological features of AD. NFTs are composed of abnormally modified forms, such as hyperphosphorylation, of tau protein. DNA methylation on Tau protein related genes in the brains of AD patients plays an important role in AD pathogenesis. In this paper, the process and role of gene methylation in abnormal Tau modification and aggregation in the development of Alzheimer's disease were discussed. The effect of DNA methylation on tau protein in the brain of patients with Alzheimer's disease will help to find new targets in the development of drugs for treating Alzheimer's disease.
