A review of the top-cited articles in a scientific discipline can identify areas of research that are well established and those in need of further development, and may, as a result, inform and direct future research efforts. Our objective was to identify and characterize the top-cited articles in traumatic brain injury (TBI). We used publically available software to identify the 50 TBI articles with the most lifetime citations, and the 50 TBI articles with the highest annual citation rates. ⋯ These findings suggest an intensified focus on mild TBI, which is perhaps a response to the dedicated attention these injuries are currently receiving in the context of sports and war, and because of their increasing incidence in developing nations. Our findings also indicate increased focus on treatment of TBI, possibly due to the limited efficacy of current interventions for brain injury. This review provides a cross-sectional summary of some of the most influential articles in TBI, and a bibliometric examination of the current status of TBI research.

ReviewChronic neurodegenerative consequences of traumatic brain injury.
Traumatic brain injury (TBI) is a serious public health concern and a major cause of death and disability worldwide. Each year, an estimated 1.7 million Americans sustain TBI of which ~52,000 people die, ~275,000 people are hospitalized and 1,365,000 people are treated as emergency outpatients. Currently there are ~5.3 million Americans living with TBI. ⋯ Single brain injury is linked to later development of symptoms resembling Alzheimer's disease while repetitive brain injuries are linked to later development of chronic traumatic encephalopathy (CTE) and/or Dementia Pugilistica (DP). Furthermore, genetic background of ß-amyloid precursor protein (APP), Apolipoprotein E (ApoE), presenilin (PS) and neprilysin (NEP) genes is associated with exacerbation of neurodegenerative process after TBI. This review encompasses acute effects and chronic neurodegenerative consequences after TBI.

In acute neuronal insult events, such as stroke, traumatic brain injury, and spinal cord injury, pathological processes of secondary neuronal injury play a key role in the severity of insult and clinical prognosis. Along with nitric oxide (NO) and carbon monoxide (CO), hydrogen sulfide (H2S) is regarded as the third gasotransmitter and endogenous neuromodulator and plays multiple roles in the central nervous system under physiological and pathological states, especially in secondary neuronal injury. The endogenous level of H2S in the brain is significantly higher than that in peripheral tissues, and is mainly formed by cystathionine β-synthase (CBS) in astrocytes and released in response to neuronal excitation. ⋯ However, there are still some reports suggest that H2S elevates neuronal Ca(2+) concentration and may contribute to the formation of calcium overload in secondary neuronal injury. H2S also elicits calcium waves in primary cultures of astrocytes and may mediate signals between neurons and glia. Consequently, further exploration of the molecular mechanisms of H2S in secondary neuronal injury will provide important insights into its potential therapeutic uses for the treatment of acute neuronal insult events.

ReviewCommunity integration after traumatic brain injury: a systematic review of the clinical implications of measurement and service provision for older adults.
To explore the scope, reliability, and validity of community integration measures for older adults after traumatic brain injury (TBI). ⋯ Enhancing integration of older adults after TBI into their community of choice, with particular emphasis on social integration and quality of life, should be a primary rehabilitation goal. However, more research is needed to inform best practice guidelines to meet the needs of this growing TBI population. It is recommended that subjective tools, such as quality of life measures, are used in conjunction with well-established community integration measures, such as the CIQ, during the assessment process.

Apolipoprotein E4 (ApoE4) has been considered to have detrimental effects on the age of onset and progression in Alzheimer's disease. Evidence continues to accumulate regarding the effects of ApoE isoforms in a number of other neurological diseases. ⋯ It further provides evidence of the effect neuroinflammation has in increasing susceptibility to cognitive decline in younger patients. Determining where these diverse diseases intersect and diverge in their relationship to ApoE provides insight into the two-hit mechanism in cognitive decline.
