Mild Traumatic Brain Injuries and Risk for Affective and Behavioral Disorders.

OBJECTIVES: Recent studies document an association between mild traumatic brain injuries (mTBIs) in children and postinjury psychiatric disorders. However. these studies were subject to limitations in the design, lack of long-term follow-up, and poorly defined psychiatric outcomes. This study determines the incidence and relative risk of postinjury new affective and behavior disorders 4 years after mTBIs. METHODS: A cohort study of mTBI cases and matched comparisons within an integrated health care system. The mTBI group included patients ≤17 years of age, diagnosed with mTBI from 2000 to 2014 (N = 18 917). Comparisons included 2 unexposed patients (N = 37 834) per each mTBI-exposed patient, randomly selected and matched for age, sex, race/ethnicity, and date of medical visit (reference date to mTBI injury). Outcomes included a diagnosis of affective or behavioral disorders in the 4 years after mTBI or the reference date. RESULTS: Adjusted risks for affective disorders were significantly higher across the first 3 years after injury for the mTBI group, especially during the second year, with a 34% increase in risk. Adjusted risks for behavioral disorders were significant at years 2 and 4, with up to a 37% increase in risk. The age group with the highest risk for postinjury affective and behavioral disorders was 10- to 13-year-old patients. CONCLUSIONS: Sustaining an mTBI significantly increased the risks of having a new affective or behavioral disorder up to 4 years after injury. Initial and ongoing screening for affective and behavior disorders following an mTBI can identify persistent conditions that may pose barriers to recovery.

A Review of Electrolyte, Mineral, and Vitamin Changes After Traumatic Brain Injury.

INTRODUCTION: Despite the prevalence of traumatic brain injury (TBI) in both civilian and military populations, the management guidelines developed by the Joint Trauma System involve minimal recommendations for electrolyte physiology optimization during the acute phase of TBI recovery. This narrative review aims to assess the current state of the science for electrolyte and mineral derangements found after TBI. MATERIALS AND METHODS: We used Google Scholar and PubMed to identify literature on electrolyte derangements caused by TBI and supplements that may mitigate secondary injuries after TBI between 1991 and 2022. RESULTS: We screened 94 sources, of which 26 met all inclusion criteria. Most were retrospective studies (n = 9), followed by clinical trials (n = 7), observational studies (n = 7), and case reports (n = 2). Of those, 29% covered the use of some type of supplement to support recovery after TBI, 28% covered electrolyte or mineral derangements after TBI, 16% covered the mechanisms of secondary injury after TBI and how they are related to mineral and electrolyte derangements, 14% covered current management of TBI, and 13% covered the potential toxic effects of the supplements during TBI recovery. CONCLUSIONS: Knowledge of mechanisms and subsequent derangements of electrolyte, mineral, and vitamin physiology after TBI remains incomplete. Sodium and potassium tended to be the most well-studied derangements after TBI. Overall, data involving human subjects were limited and mostly involved observational studies. The data on vitamin and mineral effects were limited, and targeted research is needed before further recommendations can be made. Data on electrolyte derangements were stronger, but interventional studies are needed to assess causation.

Characterizing Extreme Phenotypes for Perceived Improvement From Treatment in Persons With Chronic Pain Following Traumatic Brain Injury: A NIDILRR and VA TBI Model Systems Collaborative Project.

OBJECTIVE: To define and characterize extreme phenotypes based on perceived improvement in pain for persons with chronic pain following traumatic brain injury (TBI). SETTING: Eighteen Traumatic Brain Injury Model System (TBIMS) Centers. PARTICIPANTS: A total of 1762 TBIMS participants 1 to 30 years post-injury reporting chronic pain at their most recent follow-up interview. PRIMARY MEASURES: The Patient's Global Impression of Change (PGIC) related to pain treatment. Sociodemographic, injury, functional outcome, pain, and pain treatment characteristics. RESULTS: Participants were mostly male (73%), White (75%), middle-aged (mean 46 years), injured in motor vehicle accidents (53%), or falls (20%). Extreme phenotypes were created for an extreme improvement phenotype ( n = 512, 29.8%) defined as "moderately better" or above on the PGIC and an extreme no-change group ( n = 290, 16.9%) defined as no change or worse. Least absolute shrinkage and selection operator (LASSO) regression combined with logistic regression identified multivariable predictors of improvement versus no-change extreme phenotypes. Higher odds of extreme improvement phenotype were significantly associated with being female (odds ratio [OR] = 1.85), married versus single (OR = 2.02), better motor function (OR = 1.03), lower pain intensity (OR = 0.78), and less frequent pain, especially chest pain (OR = 0.36). Several pain treatments were associated with higher odds of being in the extreme improvement versus no-change phenotypes including pain medication (OR = 1.85), physical therapy (OR = 1.51), yoga (OR = 1.61), home exercise program (OR = 1.07), and massage (OR = 1.69). CONCLUSION: Investigation of extreme phenotypes based on perceived improvement with pain treatment highlights the ability to identify characteristics of individuals based on pain treatment responsiveness. A better understanding of the biopsychosocial characteristics of those who respond and do not respond to pain treatments received may help inform better surveillance, monitoring, and treatment. With further research, the identification of risk factors (such as pain intensity and frequency) for treatment response/nonresponse may provide indicators to prompt changes in care for individuals with chronic pain after TBI.

Traumatic brain injury as a chronic disease: insights from the United States Traumatic Brain Injury Model Systems Research Program.

Traumatic brain injury (TBI) is a global health priority, associated with substantial burden. Historically conceptualised as an injury event with finite recovery, TBI is now recognised as a chronic condition that can affect multiple domains of health and function, some of which might deteriorate over time. Many people who have had a TBI remain moderately to severely disabled at 5 years, are rehospitalised up to 10 years post-injury, and have a reduced lifespan relative to the general population. Understanding TBI as a chronic disease process can be highly informative for optimising care, which has traditionally focused on acute care. Chronic brain injury care models must be informed by a holistic understanding of long-term outcomes and the factors that can affect how care needs evolve over time. The United States Traumatic Brain Injury Model Systems of Care follows up individuals with moderate-to-severe TBI for over 30 years, allowing characterisation of the chronic (2-30 years or more post injury) functional, cognitive, behavioural, and social sequelae experienced by individuals who have had a moderate-to-severe TBI and the implications for their health and quality of life. Older age, social determinants of health, and lower acute functional status are associated with post-recovery deterioration, while younger age and greater functional independence are associated with risky health behaviours, including substance misuse and re-injury. Systematically collected data on long-term outcomes across multiple domains of health and function are needed worldwide to inform the development of models for chronic disease management, including the proactive surveillance of commonly experienced health and functional challenges.

Advancing care and research for traumatic brain injury: a roadmap.

Across all segments of society in the United States, millions of adults and children experience a traumatic brain injury (TBI) each year, which may pose lifetime health and financial burdens in the billions of dollars. Efforts have been made to advance research and care with goals to improve awareness of the causes and consequences of TBI, but gaps still remain in understanding TBI and delivering high-quality care to everyone who needs it both in military and civilian life. At the request of the Department of Defense, the National Academies of Sciences, Engineering and Medicine recently convened experts to address existing gaps in brain injury science and systems of care. Although many people who experience a TBI recover fully, others experience long-term physical, emotional, and often financial consequences to the patient and family system, and require ongoing accommodations to support their return to the communities in which they live, learn, and work. A holistic approach within the context of osteopathic medicine may be helpful and enhance contributions within the field. This article will discuss the roadmap to help guide the field, including key conclusions and recommendations for actions to advance progress over the next decade while embracing a comprehensive bio-psycho-socio-ecological model of TBI care bringing in the distinctive osteopathic approach not only to improve care and outcomes, but also to understand patient and family experiences on their TBI journey.

Traumatic Brain Injury as Frequent Cause of Hypopituitarism and Growth Hormone Deficiency: Epidemiology, Diagnosis, and Treatment.

Traumatic brain injury (TBI)-related hypopituitarism has been recognized as a clinical entity for more than a century, with the first case being reported in 1918. However, during the 20th century hypopituitarism was considered only a rare sequela of TBI. Since 2000 several studies strongly suggest that TBI-mediated pituitary hormones deficiency may be more frequent than previously thought. Growth hormone deficiency (GHD) is the most common abnormality, followed by hypogonadism, hypothyroidism, hypocortisolism, and diabetes insipidus. The pathophysiological mechanisms underlying pituitary damage in TBI patients include a primary injury that may lead to the direct trauma of the hypothalamus or pituitary gland; on the other hand, secondary injuries are mainly related to an interplay of a complex and ongoing cascade of specific molecular/biochemical events. The available data describe the importance of GHD after TBI and its influence in promoting neurocognitive and behavioral deficits. The poor outcomes that are seen with long standing GHD in post TBI patients could be improved by GH treatment, but to date literature data on the possible beneficial effects of GH replacement therapy in post-TBI GHD patients are currently scarce and fragmented. More studies are needed to further characterize this clinical syndrome with the purpose of establishing appropriate standards of care. The purpose of this review is to summarize the current state of knowledge about post-traumatic GH deficiency.

Craniofacial and traumatic brain injuries in mixed martial arts.

Objective: Mixed-Martial-Arts (MMA) has witnessed a rapid growth over the recent years. This study aims to explore the patterns and trends of head injuries in MMA.Design: Descriptive epidemiological study.Setting: Ringside physician reports of the Ultimate Fighting Championship (UFC) fights between 2016 and 2019 (inclusive) were screened. Data were extracted from the Nevada State Athletic Commission (NSAC) database. Play-by-play video analysis was also conducted.Participants: UFC fighters involved in fights sanctioned by the NSAC, between 2016 and the end of 2019 (N = 816).Independent variables: Sex, location of head injury, type of head injury, injury mechanism, number of significant head strikes, type of finish, and weight division.Main outcome measures: Head injury rates were calculated. A one-way analysis of variance (ANOVA) was used to explore any statistically significant differences between injury rates of different locations, types, and types of finishes. An independent t-test was used to determine whether any significant differences existed between the two sexes, and a Joinpoint regression analysis was used to determine the statistical significance of the trends of head injury rates across different weight divisions. P-values <0.05 were considered significant (95% CI).Results: A total of 288 head injuries in 408 fights were recorded during our study period. Head injury rate constituted 35 injuries per 100 athletic-exposures (AE) in sanctioned fights. Traumatic brain injuries (TBI) were the most common type of injury, with a rate of 16 per 100AE, significantly greater than that of fractures (p = 0.003). Males had a head injury rate of 37 per 100AE, higher than that of females which was 23 per 100AE. Technical Knockout (TKO)/ Knockout(KO) was the type of finish with the highest rate of head injuries, significantly greater than that of decision or submission (p < 0.001). In general, head injury rates were higher as weight divisions increased.Conclusion: Head injuries are prevalent in MMA. Preventive measures need to be implemented to ensure fighter safety and limit injury risk.

The Impact of Common Psychiatric and Behavioral Comorbidities on Functional Disability Across Time and Individuals in Post-9/11 Veterans.

Returning veterans often face multiple concurrent psychiatric and behavioral conditions that negatively impact reintegration into civilian life and are associated with functional disability. Understanding how conditions interact to negatively impact functioning is an important step toward developing holistic treatment approaches optimized for this population. This study utilized a cross-sectional and prospective longitudinal cohort design, applying regression algorithms to understand the relative contribution of common clinical issues to functional disability in U.S. veterans who served after the September 11, 2001 (9/11), terror attacks. Community-dwelling post-9/11 veterans (N = 397) completed detailed assessments, including common clinical condition diagnoses, combat experience, and demographics, which were used to predict functional disability (World Health Organization Disability Assessment Schedule); 205 participants were reassessed approximately 1-2 years after enrollment. Regression analyses showed a strong association between the predictor variables and functional disability, f 2 = 1.488. Validation analyses showed a high prediction ability of functional disability to independent samples, r = .719, and across time in the same individuals, r = .780. The strongest predictors included current posttraumatic stress disorder, depressive disorder, sleep disturbance, and pain diagnoses. These results demonstrate the importance of considering multiple common co-occurring conditions when assessing functional disability in post-9/11 veterans and suggest that certain syndromes contribute the most unique information to predicting functional disability with high confidence. As most U.S. veterans utilize private healthcare systems, these results have clinical utility for both Veterans Affairs and civilian healthcare practitioners in assessing and monitoring functional disability in post-9/11 veterans over time.

Decreased Risk of Dementia Among Patients With Traumatic Brain Injury Receiving Acupuncture Treatment: A Population-Based Retrospective Cohort Study.

OBJECTIVE: We conducted a longitudinal cohort study comparing the effect of acupuncture on the risk of dementia in Taiwanese individuals with traumatic brain injury (TBI). DESIGN AND PARTICIPANTS: A national health insurance database was used to identify 15 440 newly diagnosed TBI patients 20 to 70 years old between 1998 and 2007. Of the identified patients, 6308 received acupuncture following the onset of TBI (acupuncture users) and 9132 patients did not receive acupuncture (nonacupuncture users). MEASURES: All enrollees were followed until the end of 2012 to record incident cases of dementia. A Cox proportional hazards regression model was used to compute adjusted hazard ratios for the relationship of acupuncture use with dementia. RESULTS: During the follow-up period, 249 acupuncture users and 810 nonacupuncture users developed dementia, corresponding to incidence rates of 6.11 and 9.64 per 1000 person-years, respectively. Use of acupuncture was significantly associated with a lower risk of dementia. Those who received more than 5 sessions of acupuncture benefited most from it. CONCLUSIONS: Adding acupuncture to the clinical management of patients with TBI may benefit these patients by decreasing their risk of developing dementia.

Adverse Effects of Common Sports and Recreational Activities on Male Reproduction.

CONTEXT: Male factor infertility plays a significant role in infertility. Many factors have been associated with male infertility; however, the link between many sports and recreational factors and male reproduction remains poorly characterized. OBJECTIVE: To evaluate the current literature regarding the impact of many common sports and recreational factors on male reproduction. EVIDENCE ACQUISITION: A comprehensive PubMed and Embase search for relevant articles published between 1970 and 2017 was performed by combining the following search terms: male, sports (including individual sports), traumatic brain injury, sauna, hot tub, fertility, erectile dysfunction, varicocele, environment, cell phone, and laptop computer. EVIDENCE SYNTHESIS: Hypogonadism and erectile dysfunction can be associated with sports with high rates of head injuries, such as American football. Although early reports linked other sports, such as bicycling, to erectile dysfunction, subsequent studies isolated these associations to sports cycling rather than recreational cycling. Certain sports (football, basketball, handball, and volleyball) were linked to increasing prevalence and severity of varicocele, offering a potential link to male infertility. In addition, recreational activities such as sauna, hot tubs, Jacuzzis, heated car seats, and laptop use were associated with high testicular temperature, which can impair spermatogenesis. Radio frequency electromagnetic waves from cell phones and laptops have also been shown to have deleterious effects on sperm viability and motility. CONCLUSIONS: Many common sports and daily activities represent potential sources of male infertility. Clinicians should be aware of these associations in explaining idiopathic infertility in males. PATIENT SUMMARY: Male infertility is an often overlooked component of a couple's inability to conceive. We outline many common and often overlooked sports and recreational exposures that have been associated with male infertility.

Traumatic brain injury associated with dementia risk among people with type 1 diabetes.

OBJECTIVE: To examine the association between traumatic brain injury (TBI) and dementia risk among a cohort of middle-aged and elderly individuals with type 1 diabetes (T1D). METHODS: We evaluated 4,049 members of an integrated health care system with T1D ≥50 years old between January 1, 1996, and September 30, 2015. Dementia and TBI diagnoses throughout the study period were abstracted from medical records. Cox proportional hazards models estimated associations between time-dependent TBI and dementia adjusting for demographics, HbA1c, nephropathy, neuropathy, stroke, peripheral artery disease, depression, and dysglycemic events. Fine and Gray regression models evaluated the association between baseline TBI and dementia risk accounting for competing risk of death. RESULTS: A total of 178 individuals (4.4%) experienced a TBI and 212 (5.2%) developed dementia. In fully adjusted models, TBI was associated with 3.6 times the dementia risk (hazard ratio [HR] 3.64; 95% confidence interval [CI] 2.34, 5.68). When accounting for the competing risk of death, TBI was associated with almost 3 times the risk of dementia (HR 2.91; 95% CI 1.29, 5.68). CONCLUSION: This study demonstrates a marked increase in risk of dementia associated with TBI among middle-aged and elderly people with T1D. Given the complexity of self-care for individuals with T1D, and the comorbidities that predispose them to trauma and falls, future work is needed on interventions protecting brain health in this vulnerable population, which is now living to old age.

Integrated Health Care Management of Moderate to Severe TBI in Older Patients-A Narrative Review.

PURPOSE OF REVIEW: Traumatic brain injuries are common, especially within the elderly population, which is typically defined as age 65 and older. This narrative review aims at summarizing and critically evaluating important aspects of their health care management in covering the entire pathway from prehospital care to rehabilitation and beyond. RECENT FINDINGS: The number of older patients with traumatic brain injury (TBI) is increasing, and there seem to be differences in all aspects of care along their pathway when compared to younger patients. Despite a higher mortality and a generally less favorable outcome, the current literature shows that older TBI patients have the potential to make significant improvements over time. More research is needed to evaluate the most efficient and integrated clinical pathway from prehospital interventions to rehabilitation as well as the optimal treatment of older TBI patients. Most importantly, they should not be denied access to specific treatments and therapies only based on age.

Sleep outcomes following sleep-hygiene-related interventions for individuals with traumatic brain injury: A systematic review.

BACKGROUND: Sleep disturbance is commonly reported following traumatic brain injury (TBI) and can adversely impact health and wellbeing and interfere with the rehabilitation process. As such, effective treatment of sleep disturbance is critical for overall recovery. Sleep hygiene, which is non-invasive, low cost, and low risk, could serve as a suitable first line of treatment for individuals experiencing sleep disturbance post-TBI. OBJECTIVE: To assess the efficacy of sleep hygiene on sleep outcomes post-TBI. DESIGN: PsycINFO, Medline and EMBASE databases were systematically searched using mesh terms and keywords related to 'traumatic brain injury', 'sleep' and 'treatment'. Studies that met inclusion criteria were assessed on their methodological quality using validated assessment tools. RESULTS: Ten studies met inclusion criteria, none of which contained a child or adolescent population. Their methodological quality varied. The following interventions were shown to improve sleep outcomes amongst adults with TBI: Cognitive Behaviour Therapy for Insomnia, blue light therapy, Problem Solving Treatment and combined sleep hygiene and Prazosin. There was mixed evidence for the efficacy of exercise on sleep outcomes. CONCLUSION: Preliminary findings suggest that some sleep-hygiene-related interventions, either in isolation or in combination with other treatments, may reduce sleep difficulties post-TBI.

Prevalence of hearing loss and tinnitus in Iraq and Afghanistan Veterans: A Chronic Effects of Neurotrauma Consortium study.

The purpose of this study was to describe the prevalence of hearing loss and tinnitus in a cohort of Iraq and Afghanistan Veterans (IAV) with common post-deployment conditions, including traumatic brain injury (TBI), post-traumatic stress disorder (PTSD), and other typical post-concussive conditions such as headaches and vertigo/dizziness. This retrospective observational study used data from the national Veterans Health Administration (VA) data repository from fiscal years 2001-2014. Veteran data was included if there were at least three years of VA care, with one or more years of care in 2007 or after. We identified comorbidities that may be associated with post-deployment hearing loss or tinnitus including TBI, PTSD, depression, and common post-concussive symptoms using International Classification of Diseases, 9th Revision, Clinical Modification codes. A multinomial logistic regression analysis was used to examine conditions associated with hearing loss or tinnitus. Among IAV, 570,332 were included in the final analysis. Of these, 7.78% of these were diagnosed with hearing loss alone, 6.54% with tinnitus alone, and 6.24% with both hearing loss and tinnitus. Comorbid TBI, PTSD, and depression were significantly associated with increased rates of hearing loss, tinnitus, or both conditions together. Older individuals, males, and those with TBI, PTSD, or vertigo/dizziness were significantly more likely to have hearing loss, tinnitus, or both. In order to provide more holistic post-deployment support, this myriad of conditions should be carefully considered in the planning of clinical care and beyond.

Plasma Potassium Concentration on Admission Correlates with Neurologic Outcome in Traumatic Brain Injury Patients Treated with Targeted Temperature Management: A Post Hoc Analysis of a Multicenter Randomized Controlled Trial.

BACKGROUND: Recent studies have focused on the association between plasma electrolytes, particularly potassium level and neurologic outcomes in patients with traumatic brain injury (TBI). We hypothesized that potassium level on admission is an indicator for initiation of targeted temperature management in patients with severe TBI. METHODS: We re-evaluated the Brain Hypothermia Study data based on the potassium levels on admission (i.e., hypokalemia [<3.5 mEq/L] or normokalemia [3.5-5 mEq/L]) and compared these values and Glasgow Outcome Scale scores at 6 months by per protocol analysis. Consequently, 135 patients were enrolled. Finally, groups 50 and 23 patients with hypokalemia and 34 and 23 patients with normokalemia were allocated to mild therapeutic hypothermia (MTH) and fever control groups, respectively. Baseline characteristics, complication rates, and favorable neurologic outcome rates were compared between the two groups. RESULTS: In the normokalemia patients, fever control management was associated with a significant increase in favorable neurologic outcome compared with those in the MTH group (68.2% vs. 35.3%; P = 0.03). The complication rate was significantly higher in the MTH group than in the fever control group for patients with normokalemia (23.4% vs. 0%; P = 0.03). Conversely, hypokalemia patients in the MTH group revealed relatively better favorable neurologic outcomes compared with those in the fever control group (52.0% vs. 39.1%; P = 0.33). CONCLUSIONS: The initial potassium level may be an indicator in determining appropriate targeted temperature management for patients with TBI. Fever control may be considered instead of MTH for normokalemia patients with TBI on admission.

Increased Risk of Post-Trauma Stroke after Traumatic Brain Injury-Induced Acute Respiratory Distress Syndrome.

This study determines whether acute respiratory distress syndrome (ARDS) is an independent risk factor for an increased risk of post-traumatic brain injury (TBI) stroke during 3-month, 1-year, and 5-year follow-ups, respectively, after adjusting for other covariates. Clinical data for the analysis were from the National Health Insurance Database 2000, which covered a total of 2121 TBI patients and 101 patients with a diagnosis of TBI complicated with ARDS (TBI-ARDS) hospitalized between January 1, 2001 and December 31, 2005. Each patient was tracked for 5 years to record stroke occurrences after discharge from the hospital. The prognostic value of TBI-ARDS was evaluated using a multivariate Cox proportional hazard model. The main outcome found that stroke occurred in nearly 40% of patients with TBI-ARDS, and the hazard ratio for post-TBI stroke increased fourfold during the 5-year follow-up period after adjusting for other covariates. The increased risk of hemorrhagic stroke in the ARDS group was considerably higher than in the TBI-only cohort. This is the first study to report that post-traumatic ARDS yielded an approximate fourfold increased risk of stroke in TBI-only patients. We suggest intensive and appropriate medical management and intensive follow-up of TBI-ARDS patients during the beginning of the hospital discharge.

Estimación de prevalencia de niños con enfermedades limitantes de la vida en un hospital pediátrico de alta complejidad / Prevalence of patients with life-limiting conditions in a high complexity pediatric hospital

En Chile fallecen aproximadamente 800 niños menores de 15 años por diversas causas, entre ellas, por enfermedades sin tratamiento curativo. La Sociedad Chilena de Pediatría creó el Comité de Niños y Adolescentes con Necesidades Especiales en Atención de Salud (NANEAS), que entregó las pautas para una atención integral de estos pacientes, incluyendo los cuidados paliativos (CP). Resulta indispensable conocer el número y características de los pacientes que padecen enfermedades limitantes de la vida (ELV) para elaborar programas de atención que prioricen por un cuidado ambulatorio bajo la supervisión de equipos multidisciplinarios. Objetivo: Estimar la prevalencia de pacientes con ELV en un hospital pediátrico de alta complejidad. Pacientes y método: Se revisaron los egresos de las Unidades de Pediatría General y Unidad de Paciente Crítico del Hospital Roberto del Río, durante el 2009 y 2010. Se seleccionaron los casos con diagnósticos de ELV según CIE-10, registrando datos demográficos y clasificándolos según los grupos de la ACT para ELV. Se excluyeron pacientes con cáncer avanzado. Resultados: De 6585 pacientes egresados, 190 tenían diagnóstico ELV (2.89 por ciento). Los lactantes fueron el grupo más numeroso (33 por ciento). El 51,6 por ciento de los pacientes pertenecían al grupo 4 (parálisis cerebral severa, genopatías complejas, TEC con secuelas graves) y todos fueron atendidos por 3 o más especialistas. Conclusión: Los niños con ELV constituyen un grupo emergente entre los pacientes pediátricos hospitalizados, demandando una atención de alta complejidad. Es un desafío implementar políticas públicas que optimicen su manejo y permitan planificar unidades especializadas para su atención, incluyendo los CP.

In Chile, approximately 800 children under the age of 15 years die from a variety of causes, including life-limiting conditions (LLC). The Chilean Society of Pediatrics established a Committee on Children and Adolescents with Special Health Care Needs (NANEAS), which established guidelines for comprehensive care of these patients, including palliative care (PC). It is essential to know the number and characteristics of patients with LLC, in order to develop programs for outpatient care under the supervision of multidisciplinary teams. Objective: To estimate the prevalence of patients with LLC in a high complexity pediatric hospital. Patients and methods: We reviewed the discharges from General Pediatric Units and the Critical Patient Unit at the Roberto del Rio Hospital during 2009 and 2010. We selected patients with LLC according to ICD-10. Their demographic characteristics were registered and classified into the four ACT groups. Patients with advanced cancer were excluded. Results: Of 6585 patients discharged, 190 were diagnosed as LLC (2.89 percent). Infants were the largest group (33 percent). 51.6 percent of patients belonged to group 4 (severe cerebral palsy, genopathies, serious sequelae of traumatic brain injury) and all were attended by at least three specialists. Conclusion: Children with LLC are an emerging group among hospitalized pediatric patients and they are demanding attention of high complexity. It is a challenge to design and implement public policies that can optimize health care for these patients, and facilitate the establishement of specialized units for this purpose, including PC.

Calidad de vida y sobrecarga de los cuidadores de pacientes con daño cerebral adquirido / Quality of life and burden of carers of patients with acquired brain injury

Introducción. El impacto en salud del daño cerebral adquirido (DCA) se manifiesta no solo en los pacientes sino también en la pérdida de calidad de vida relacionada con la salud (CVRS) de sus cuidadores. Los objetivos de este estudio fueron medir tanto la pérdida de CVRS como la sobrecarga de los cuidadores de pacientes con DCA. Material y métodos. Se llevó a cabo un estudio retrospectivo con 76 cuidadores de pacientes con DCA. La encuesta recogió información acerca de las características sociodemográficas, la carga de los cuidados (escala de Zarit) y la CVRS (cuestionario EuroQol) de los cuidadores. Para analizar el efecto de las diferentes variables se construyeron modelos de regresión lineal múltiple y regresión logística. Resultados. Los cuidadores fueron predominantemente mujeres de más de 50 años, jubiladas o dedicadas a las tareas domésticas y que cuidaban a su marido o a uno de sus padres. Un tercio mostró un riesgo alto de claudicación. La media de la CVRS obtenida con EuroQol pasó de una cifra similar a la de la población general (0,90) en el grupo sin sobrecarga a 0,67 en el grupo con riesgo de claudicación. Los modelos de regresión explicaron mejor la sobrecarga que la pérdida de calidad de vida. Conclusiones. Los cuidadores de pacientes con daño cerebral sufren una importante pérdida de CVRS con relación a la población general. El deterioro radica en las dimensiones mentales y depende del nivel de la sobrecarga(AU)

Introduction. The health impact of acquired brain injury (ABI) is not only apparent in the patient, but also in the loss of health related quality of life (HRQol) of their carers. The objectives of this study were to measure the loss of HRQol as well as the burden of the carers of patients with ABI. Material and methods. A retrospective study was conducted with 76 carers of patients with ABI. A questionnaire was used to collect information on the sociodemographic aspects, carer burden (Zarit Scale) and the HRQol (EuroQol Questionnaire) of the carers. A multiple linear regression model was constructed to analyse the effect of the different variables. Results. The carers were predominantly women over 50years, retired or dedicated to domestic tasks and who cared for their husband or one of their parents. One third showed a high risk of claudication. The mean HRQol obtained with the EuroQol went from a similar score to that of the general population (0.9) in the group without burden, to 0.67 in the group with risk of claudication. The regression models explained the burden better than the loss in quality of life. Conclusions. Carers of patients with brain injury suffer a significant loss in HRQol compared to the general population. The deterioration arises from the mental dimensions and depends on the level of burden(AU)
