ATP-binding cassette (ABC) subfamily A member 3 (ABCA3) is a lipid transporter expressed in alveolar type II cells and localized in the limiting membrane of lamellar bodies. It is crucial for pulmonary surfactant storage and homeostasis. Mutations in the ABCA3 gene are the most common genetic cause of respiratory distress syndrome in mature newborns and interstitial lung disease in children. Apart from lung transplantation, there is no cure available. To address the lack of causal therapeutic options for ABCA3 deficiency, a rapid and reliable approach is needed to investigate variant-specific molecular mechanisms and to identify pharmacological modulators for mono- or combination therapies. To this end, we developed a phenotypic cell-based assay to autonomously identify ABCA3 wild-type-like or mutant-like cells by using machine-learning algorithms aimed at identifying morphological differences in WT and mutant cells. The assay was subsequently used to identify new drug candidates for ABCA3 specific molecular correction by high-content screening of 1,280 food and drug administration-approved small molecules. Cyclosporin A (CsA) was identified as a potent corrector, specific for some, but not all ABCA3 variants. Results were validated by our previously established functional small format assays. Hence, CsA may be selected for orphan drug evaluation in controlled repurposing trials in patients.The cytoplasmic accumulation and aggregates of TARDBP/TDP-43 (TAR DNA binding protein) are a pathological hallmark in amyotrophic lateral sclerosis and frontotemporal lobar degeneration. We previously reported that the primate specific cleavage of TARDBP accounts for its cytoplasmic mislocalization in the primate brains, prompting us to further investigate how the cytoplasmic TARDBP mediates neuropathology. Here we reported that cytoplasmic mutant TARDBP reduced SQSTM1 expression selectively in the monkey brain, when compared with the mouse brain, by inducing SQSTM1 mRNA instability via its binding to the unique 3'UTR sequence (GU/UG)n of the primate SQSTM1 transcript. Overexpression of SQSTM1 could diminish the cytoplasmic C-terminal TARDBP accumulation in the monkey brain by augmenting macroautophagy/autophagy activity. Our findings provide additional clues for the pathogenesis of cytoplasmic TARDBP and a potential therapy for mutant TARDBP-mediated neuropathology.

Motorcycles, moped scooters and bicycles are commonly involved in traffic accidents and riders often suffer significant morbidity and mortality. The aim of this study is to compare and categorize the different injury patterns and fractures suffered by riders of each vehicle type after a traffic accident.

Data from a level 1 trauma center in Las Vegas, Nevada were analyzed. Traffic accident victims riding a motorcycle, moped, or bicycle from 2013 to 2017 were included. Injury location and fracture location were assigned to six and sixteen categorical locations, respectively. Descriptive statistics, including frequency counts for categorical data and mean for continuous data, were calculated for the full sample and for each of the vehicle types. Logistic regression was performed on race, categorized age, vehicle type and helmet use to calculate adjusted odds ratios for injury type between the three groups.

Of the 2115 patients, 1372 were motorcyclists, 356 were moped scooter riders and 387 were bicyclistsmost common fracture and injury patterns between the three groups. learn more Head and neck injuries were much more common in moped and bicycle riders compared to motorcyclists. This is most likely due to the significantly higher percentage of motorcycle riders who wore a helmet. Counseling regarding helmet and protective equipment use, especially among moped and bicycle riders is essential to reduce head injuries.This article is concerned with the dynamics of malaria infection model with diffusion and delay. The disease free threshold ℜ0 and the immune response threshold value ℜ1 of the malaria infection are obtained, which characterize the stability of the disease free equilibrium and infection equilibrium (with or without immune response). In addition, fluctuations occur when the model undergoes Hopf bifurcation as the delay passes through a certain critical value τ0. In this case, periodic oscillation appears near the positive steady state, which implies the recurrent attacks of disease. Finally, numerical simulations are provided to illustrate the theoretical results.

The coronavirus disease 2019 (COVID-19) pandemic has led to a dramatic increase in the number of survivors of critical illness. These survivors are at increased risk of physical, psychological, and cognitive impairments known collectively as Post-Intensive Care Syndrome (PICS). Little is known about the prevalence of PICS in COVID-19 survivors.

To report the prevalence of physical, psychological, and cognitive impairment among COVID-19 intensive care unit (ICU) survivors receiving follow-up care in an ICU recovery clinic, to assess for associations between PICS and ICU-related factors, and to compare the cohort of ICU survivors who attended post-ICU clinic to a cohort of ICU survivors who did not.

We performed a retrospective cohort study of COVID-19 ICU survivors admitted from March to May 2020 who were subsequently seen in a post-ICU recovery clinic in New York City. We abstracted medical chart data on available clinical screening instruments for physical, psychological, and cognitive impairment. Asso19 ICU survivors who attended ICU recovery clinic and those who did not.

PICS is common in COVID-19 survivors. We did not find any association with length of ICU stay, the use of benzodiazepines, steroids, or paralytics.

In cancer, the tumor cell-intrinsic effects of autophagy are highly context specific, which could promote cancer cell survival or induce programmed cell death. Here, we reveal that OLR1/LOX-1 (oxidized low density lipoprotein receptor 1), a scavenger receptor highly expressed in esophageal cancer cells, is involved in tumorigenesis by suppressing autophagic cell death. Mechanistically, OLR1 binding to RACK1 activates MAP2K/MEK-MAPK/ERK signaling leading to TFEB (transcription factor EB) being trapped outside the nucleus and inhibiting autophagy. In addition, we identify a polysaccharide which causes the degradation of OLR1 and suppresses this autophagic pathway to inhibit tumorigenesis. This study demonstrates novel molecular mechanisms underlying the tumor-suppressive effect of autophagy and provides therapeutic insight for esophageal cancer.

Induction programmes aim to ease the transition from medical student to doctor. The interim foundation year 1 (FiY1) placement, introduced in the first COVID-19 wave, provided experience in advance of the Foundation Year 1 (FY1) start in August; providing more time and enhanced responsibilities than traditional induction programmes. This study examines the effects of the FiY1 placement on anxiety levels and preparedness for FY1.

This was a descriptive cross-sectional study using data from four cohorts of FY1s who completed the online National FY1 induction survey from 2017 to 2020 (

 = 4766). Questions evaluated self-reported preparedness and anxiety levels. Differences in preparedness and anxiety levels of FiY1 and non-FiY1 participants in 2020, and the 2017-2019 participants (non-FiY1 controls), were evaluated.

FiY1s in 2020 reported higher self-reported preparedness (79%) than non-FiY1s (54%) in 2020 (

 = <0.001) and the control 2017-2019 cohort (63.8%) (

 < 0.001). Fewer FiY1s experienced pathological anxiety (29.3% versus 40.8% for non-FiY1s;

 = 0.001).

Time spent in an FiY1 role is associated with an increase in self-perceptions of preparedness and a reduction in anxiety. These data indicate that time spent in an FiY1 role may have utility in further improving the transition period from medical school to FY1.

Despite the benefits of wheelchair-mounted robotic arms (WMRAs), occupational therapists are not yet widely involved in the recommendation or implementation of these assistive devices. The purpose of this study was to investigate and compare the current practices and perspectives of occupational therapists who had and had not recommended a WMRA on the recommendation, training, and implementation of WMRAs.

This was a descriptive cross-sectional study. An online survey was sent to Canadian, European, and American occupational therapists who had or had not worked with WMRAs. Respondents were asked close-ended questions about their experience, role, barriers, motivations, and future needs regarding WMRAs. We compared results between respondents who had and had not recommended WMRAs using descriptive statistics.

Ninety-three North American and European occupational therapists completed the survey. Of those, 29 (31.2%) had recommended a WMRA, mostly the JACO robotic arm (

In particular, future research and health policies should focus on access to sufficient funding, formal training, and resources for occupational therapists relative to their role in recommending and implementing WMRAs.Objective The optimal use of drug combinations for the management of asthma is providing significant results. This has prompted Interasma (Global Asthma Association) to take a position on inhaled triple therapy in asthma.Methods We performed an extensive literature research to clinical trials, meta-analyses, randomized controlled trials and systematic reviews.Results Starting from an extensive literature review, Interasma executive committee discussed and approved this Manifesto, developed by Interasma scientific network (INES) members.Conclusions The manifesto describes the evidence gathered to date and states, advocates, and proposes issues on inhaled corticosteroid (ICS) plus long-acting beta 2 agonist (LABA) and long-acting muscarinic antagonists (LAMA) with the aim of challenging assumptions, fostering commitment, and bringing about change.

Craniofacial structure is thought to modulate the effect of weight loss on OSA, but whether this affects metabolic profile after weight loss compared with continuous positive airway pressure(CPAP) is unknown among obese Chinese patients with obstructive sleep apnea(OSA).

To compare the change in metabolic profile between lifestyle modification program(LMP), stratified by craniofacial phenotype, and CPAP therapy for 6 months.

We randomly assigned 194 patients with BMI≥25kg/m2 and moderate-to-severe OSA to receive LMP or CPAP therapy for 6 months in a 21 ratio. Assessments included computed tomography for assessing maxillomandibular volume(MMV), high sensitivity C-reactive protein(hsCRP) and insulin sensitivity. Measurements and Main Results(mean±SD or median[interquartile range]) Among 128 and 66 subjects in LMP group and CPAP group, respectively, hsCRP reduced more in LMP group than the CPAP group (-0.7[-1.4 to -0.0]mg/L vs -0.3[-0.9 to 0.4]mg/L, p=0.012). More patients in LMP group achieved low hsCRP(<1mg/L) than the CPAP group(21.
