The growing availability of single-cell and spatially resolved transcriptomics has led to the development of many approaches to infer cell-cell communication, each capturing only a partial view of the complex landscape of intercellular signalling. Here we present LIANA+, a scalable framework built around a rich knowledge base to decode coordinated inter- and intracellular signalling events from single- and multi-condition datasets in both single-cell and spatially resolved data. By extending and unifying established methodologies, LIANA+ provides a comprehensive set of synergistic components to study cell-cell communication via diverse molecular mediators, including those measured in multi-omics data.

This case report discusses the functional outcomes and multidisciplinary coordination of care for a patient with hemiplegia due to stroke complicated by a migrated inferior vena cava (IVC) filter embedded in the right side of the heart. The patient suffered an acute right-sided stroke with hemorrhagic transformation requiring hemicraniectomy with left hemiplegia. The patient developed a subsequent pulmonary embolism requiring IVC filter placement as anticoagulation was contraindicated due to risk of further intracranial hemorrhage.

An important case is cell-cell communication, where metabolites, secreted into the microenvironment, initiate signaling cascades by binding to intra- or extracellular receptors of neighboring cells. Protein-protein cell-cell communication interactions are routinely predicted from transcriptomic data.

Most patients had a complete recovery from the acute infection, however, a large number of the affected individuals experienced symptoms that persisted more than 3 months after diagnosis. These symptoms most commonly include fatigue, memory difficulties, brain fog, dyspnea, cough, and other less common ones such as headache, chest pain, paresthesias, mood changes, muscle pain, and weakness, skin rashes, and cardiac, endocrine, renal and hepatic manifestations.

Here, we describe a rich atlas of short- and long-read single-cell transcriptomes of over 37,000 cells across intraerythrocytic asexual and sexual development. We used the atlas to explore transcriptional modules and exon usage along sexual development and expanded it to include malaria parasites collected from four Malian individuals naturally infected with multiple strains.

Structural priming has received recent attention as a potential training method for PWA. We investigated the feasibility and efficacy of a collaborative structural priming task delivered the internet, , in facilitating sentence production in PWA and healthy adults.

Resilience interventions have been proposed as one strategy to influence these outcomes.
Objective: The objective of this observational pilot study was to determine the feasibility and acceptability of the Resilient Living program among persons with stroke or brain tumor (BT) admitted for comprehensive acute inpatient rehabilitation and/or their family caregivers.
Background: Acquired brain injury (BI) is associated with negative mental health outcomes for both people with BI, their caregivers (CG), and patient-CG dyads, which may be mitigated through increased resilience. However, little is known regarding the efficacy of resilience interventions focused on CGs of individuals with BI, as well as dyads, which may be instrumental for positive outcomes.
Objective: To systematically review the evidence of the efficacy of resilience interventions focused on CGs and/or dyads of individuals with BI.
Long COVID, a term used to describe ongoing symptoms after COVID-19 infection, parallels the course of other postviral syndromes. Neuropsychiatric symptoms of long COVID can be persistent and interfere with quality of life and functioning. Within the biopsychosocial framework of chronic illness, rehabilitation professionals can address the neuropsychiatric sequelae of long COVID.

We combine this new data with published case series re-analyzed here (117 nerve injuries; 58 patients) to provide a comprehensive accounting of lesion sites. The most common are ulnar (25.

A primary symptom for many patients is exertional dyspnoea which may persist even beyond recovery from the viral infection. Respiratory muscle (RM) performance was hypothesised as a contributing factor to the severity of coronavirus disease 2019 (COVID-19) symptoms, such as dyspnoea, and outcomes.

Little is known about the physician stressors unique to those providing care in inpatient rehabilitation facilities (IRFs) and what strategies such facilities have used to help mitigate burnout among inpatient physiatrists.
Objective: To identify what IRF leaders perceive as stress points contributing to burnout among inpatient rehabilitation physicians and what, if any, interventions their programs have implemented to help mitigate physician burnout.
Climate change is impacting the function and distribution of habitats used by marine, coastal, and diadromous species. These impacts often exacerbate the anthropogenic stressors that habitats face, particularly in the coastal environment. We conducted a climate vulnerability assessment of 52 marine, estuarine, and riverine habitats in the Northeast U.

Here, we present Swift Profiling Of Transcriptomes (SPOT) as a web tool that allows not only differential expression analysis but also fast ranking of genes fitting transcription profiles of interest. Based on a heuristic approach the spot algorithm ranks the genes according to their proximity to the user-defined gene expression profile of interest.

Many survivors from severe coronavirus disease 2019 (COVID-19) suffer from persistent dyspnea and fatigue long after resolution of the active infection. In a cohort of 21 consecutive severe post-COVID-19 survivors admitted to an inpatient rehabilitation hospital, 16 (76%) of them had at least one sonographic abnormality of diaphragm muscle structure or function. This corresponded to a significant reduction in diaphragm muscle contractility as represented by thickening ratio (muscle thickness at maximal inspiration/end-expiration) for the post-COVID-19 compared to non-COVID-19 cohorts.

Locked-in syndrome is a rare and devastating condition that results in tetraplegia, lower cranial nerve paralysis, and anarthria with preserved cognition, vertical gaze, and upper eyelid movements. Although acute management is much like that of any severe stroke, rehabilitation and recovery of these patients have not been previously described. Challenges relevant to this population include blood pressure management and orthostasis, timing and appropriateness of reinstating oral feeding, ventilatory support, decannulation after tracheostomy, bowel and bladder management, vestibular dysfunction, and eye care.

Neuralgic amyotrophy is a poorly understood neuromuscular disorder affecting peripheral nerves mostly within the brachial plexus distribution but can also involve other sites including the phrenic nerve. In the classic form of the syndrome it causes proximal upper limb and neck pain on the affected side with subsequent muscle weakness that can be highly heterogeneous. Nocturnal noninvasive ventilation support is a first-line treatment after phrenic mononeuropathy.
