要旨

Objectives:

Concussion is common in early childhood, yet the rate of persisting symptoms after concussion (PSaC) is unknown. We sought to determine the frequency of PSaC after early childhood concussion and identify potential predictors of PSaC.

Methods:

We conducted a cohort study enrolling children aged 6 months to younger than 6 years presenting to Canadian and US emergency departments (EDs) with concussion or orthopedic injury (OI) and uninjured children from the community (community controls [CCs]). The primary outcome was PSaC at 1 month after injury determined by reliable change analysis. PSaC were also tracked through 12 months after injury. Potential predictors of PSaC were analyzed using multivariable logistic regression.

Results:

We enrolled 418 children: 235 with concussion, 108 with OI, and 75 CCs. Median age was 2.8 years, and 50.7% were male. At 1 month, PSaC were documented in 28% of children with concussion, higher than in the OI group (10%, P = .006) and the CC group (2%, P < .001). After concussion, PSaC were documented in 24% of children at 3 months and 16% at 12 months. Total symptom burden in the ED predicted PSaC at 1 month (odds ratio, 1.108; 95% CI, 1.004-1.223; P = .04). Age, loss of consciousness, receiving brain imaging in the ED, attending daycare or school, and parent education did not predict PSaC.

Conclusions:

PSaC are common after early childhood concussion. Acute symptom burden in the ED predicts PSaC at 1 month. Greater focus on research in this age group and the development of clinical infrastructure is necessary to address these ongoing symptoms.

Diabetes: Symptoms, Diagnosis, and Complications

Diabetes: Symptoms, Diagnosis, and Complications

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Negative and Cognitive Symptoms of Schizophrenia

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Asthma-III: Symptoms and Complications

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Pleural Effusion II: Symptoms and Management

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.

Erikson's Theory on Socioemotional Development during Childhood

Erikson's Theory on Socioemotional Development during Childhood

Erik Erikson, a stage theorist, adapted Freud's theory to emphasize social factors in personality development throughout life, a concept known as psychosocial development. Unlike Freud, who focused on early childhood, Erikson believed that personality evolves across eight life stages, each marked by a specific challenge or "crisis." Successful resolution of each stage fosters competence, while failure may lead to feelings of inadequacy.
The first four of Erikson's eight...
