A pediatric injury prevention course has not been available as a massive open online course (MOOC). Creating a comprehensive topic course is particularly challenging because the traditional, week-by-week linear curriculum design is often a barrier to learners interested in only specific topics. We created a novel, flexible course as both a 'choose your topic' MOOC for the public learner and a Small Private Online Course (SPOC) for medical students.

We describe creating '

', a course of 59 video learning segments within eight modules taught by a multidisciplinary panel of 25 nationally-recognized experts. Completion tracking and course evaluations were collected.

In 2.5years, 4,822 learners from 148 countries have enrolled. Two-thirds of learners were female. click here Median age of learners was 31years. For engagement, 19.3% (n=932) of learners attempted quizzes, and 5.2% (n=252) participated in online forum discussions. Medical professionals (n=162) claimed an average of 13 credit hours per learner. Over 200 senior medical students have taken the SPOC.

Recent studies also implicate a role of MLKL in endosomal trafficking, which is not always dependent on RIPK3. Using mouse Neuro-2a and L929 as well as human HEK293 and HT29 cells, we show here that MLKL is phosphorylated in response to serum and amino acid deprivation from the culture medium, in a manner that depends on CAMK2/CaMKII (calcium/calmodulin dependent protein kinase II) but not RIPK3. The starvation-induced increase in MLKL phosphorylation was accompanied by decreases in levels of lipidated MAP1LC3B/LC3B (microtubule associated protein 1 light chain 3 beta; LC3-II) and SQSTM1/p62 (sequestosome 1), markers of autophagosomes. These changes were prevented by disrupting either MLKL or CAMK2 by pharmacology and genetic manipulations. Moreover, disrupting MLKL or CAMK2 also inhibited the incorporation of LC3-II into autolysosomes, demonstrating a role of the CAMK2-MLKL pathway in facilitating autophagic flux during short-term starvation, in contrast to necroptosis which suppressed autophagic flux. Furthermore, unlike the necroptotic pathway, the starvation-evoked CAMK2-mediated MLKL phosphorylation protected cells from starvation-induced death. We propose that upon nutrient deprivation, MLKL is activated by CAMK2, which in turn facilitates membrane scission needed for autophagosome maturation, allowing the proper fusion of the autophagosome with lysosome and the subsequent substance degradation. This novel function is independent of RIPK3 and is not involved in necroptosis, implicating new roles for this pseudokinase in cell survival, signaling and metabolism.

Rebleeding is a frequent complication of peptic ulcer bleeding (PUB) and is associated with increased mortality. Blood pressure and heart rate are two easy non-invasive measurements to evaluate the hemodynamics and therefore a standard observation during hospitalization.

We aimed to investigate the dynamics of systolic blood pressure and heart rate up to time of peptic ulcer rebleeding.

Retrospective matched cohort study. Hemodynamics in patients with peptic ulcer rebleeding was compared to hemodynamics in a matched control group consisting of patients with PUB without rebleeding. Blood pressure and heart rate in the six hours up to diagnosis of rebleeding was compared with baseline in the case cohort as well as with the matched control group.

Thirty-eight patients with peptic ulcer rebleeding and 66 controls were included. Mean age was 75 years, 62% were males and 30-day mortality was 23%. Baseline systolic blood pressure in cases was 114 mmHg. Compared to baseline, we found significant decrease in systolic blood pressure two hours before rebleeding (4 mmHg;

 = 0.041) and one hour before rebleeding (14 mmHg;

 = 0.0002). Mean systolic blood pressure 30 min before rebleeding was 89 mmHg. No significant change was found in heart rate (

 = 0.99). In the control group no change was found in systolic blood pressure or heart rate.

In patients with peptic ulcer rebleeding, hypotension develops 1-2 h before other symptoms of rebleeding. Thus, close monitoring of blood pressure is needed in order to ensure early identification of rebleeding in high-risk patients.

In this study, the effect of a remotely supervised, home-based, family-centered individualized rehabilitation program of motor activities for individuals with Rett syndrome (RTT) was evaluated.

Thirteen participants with classic genetically confirmed RTT followed by a three-month program of motor activities at home. A total of 47 rehabilitative goals were set. Goals achievement, motor function, and parental satisfaction were evaluated. Each program was carried out by the participant's parents and remotely supervised via Skype calls, twice by a therapist experienced in RTT rehabilitation.

Thirty-seven (78.7%) rehabilitative goals were achieved or overachieved. Ten participants (76.9%) significantly increased their gross motor functional level with a medium size effect (0.604). Parental reports of the involved families suggest, on average, a high level of usefulness of the program (4.4/5), adherence to the program (4.4/5), and general satisfaction (4.5/5).

Our findings strongly support the implementatioctivity program carried out by the primary caregiver supports motor functioning in RTT.Therapists should consider family members' motivation to carry out the activities and integrate them into the family's daily routine.The program should be flexible to adapt to any sudden change in medical and environmental conditions, functional ability, and family members' motivational levels.Purpose To evaluate functional outcomes, care needs and cost-efficiency of specialist rehabilitation for a multi-centre cohort of inpatients with spinal cord injury (SCI)-comparison based on age and aetiology.Methods and materials Retrospective analysis of prospectively collected data from the UK Rehabilitation Outcomes Collaborative (UKROC) national clinical database from 2012-2019. Adults with SCI admitted for a rehabilitation programme in levels 1 and 2 specialist rehabilitation Units in England, were included if they had valid UK Functional Assessment Measure (UK FIM + FAM) and Northwick Park Dependency Scale (NPDS) scores recorded on admission and discharge (n = 2506 of 3321 admissions).Results Approximately 425 patients were admitted yearly. 1344(56%) patients were under 65. 736(29%) had traumatic aetiology. Older and Traumatic SCI patients were more likely to have cervical cord damage (X2, p  less then  0.001). There was a significant improvement in all parameters of functional independence (UK FIM + Fits continue to provide highly cost-efficient care.The mean annual savings amount to £25,500 per patient. With a mean admission rate of 425 patients, this would generate total savings in excess of £10 million per year for the cohort.Specialist rehabilitation services play an important, but under-recognised, role in the spinal cord injury care pathway.

Ketamine has remained the most commonly used illicit drug among adolescents in Taiwan. A dual process model proposes that addictive behaviors develop in adolescents as a result of an imbalance between an appetitive, approach-oriented system (implicit and explicit attitudes) and a regulatory executive system (cool and hot executive functions). We aimed to examine the appetitive and regulatory processes in adolescent ketamine users in comparison to matched healthy adolescents.

The participants were 30 adolescent ketamine users and 32 nondrug controls, matched with gender, age, education years, and education systems. Both groups completed the affective priming task (APT), the stop-signal task (SST), an Iowa Gambling Task (IGT), and finally a Drug Use Disorders Identification Test Extended (DUDIT-E).

The controls had higher positive and negative outcome expectancy with respect to using ketamine compared to the adolescent ketamine users. There was no significant between-group performance difference in APT.developed accordingly. More advocacies on ketamine's aversive outcomes are needed, particularly on campus in order to reduce substance misuse.Seizures triggered by skin application, inhalation or ingestion of over-the-counter medications containing eucalyptus oil are known. We report five children who suffered likewise. We made a systematic search for all reported cases and performed a pooled analysis to provide a comprehensive estimate of the type of seizures, their management and outcome. In 110 cases (49 children), inhalational use was the most predominant, generalised tonic-clonic (the commonest semiology) and levetiracetam was the most common anti-convulsant treatment used. Most cases had an uneventful recovery. Adults were less likely to have prolonged and multiple seizures, requiring intensive care or mechanical ventilation.

Literature is inconclusive regarding the association between antiplatelet agents use and outcome after aneurysmal subarachnoid hemorrhage.

To investigate the association between clinical outcome and prehemorrhage use in aneurysmal subarachnoid hemorrhage patients as well as the impact of thrombocyte transfusion on rebleed and clinical outcome.

Data were collected from prospective databases of two European tertiary reference centers for aneurysmal subarachnoid hemorrhage patients. Patients were divided into "antiplatelet-user" and "non-user" according to the use of acetylsalicylic acid prior to the hemorrhage. Primary outcome was poor clinical outcome at six months (Glasgow Outcome Scale score 1-3). Secondary outcomes were in-hospital mortality and impact of thrombocyte transfusion.

Of the 1033 patients, 161 (15.6%) were antiplatelet users. The antiplatelet users were older with higher incidence of cardiovascular risk factors. Antiplatelet use was associated with poor outcome and in-hospital mortality. After correction for age, sex, World Federation of Neurosurgical Societies score, infarction and heart disorder, pre-hemorrhage acetylsalicylic acid use was only associated with poor clinical outcome at six months (adjusted OR 1.80, 95% CI 1.08-3.02). Thrombocyte transfusion was not associated with a reduction in rebleed or poor clinical outcome.

In this multicenter study, the prehemorrhage acetylsalicylic acid use in aneurysmal subarachnoid hemorrhage patients was independently associated with poor clinical outcome at six months. Thrombocyte transfusion was not associated with the rebleed rate or poor clinical outcome at six months.
