RESUMO

OBJECTIVES: We developed a predictive model for all-cause mortality and examined the risk factors for cause-specific mortality among people with cognitive impairment in a Japanese memory clinic-based cohort (2010-2018). METHODS: This retrospective cohort study included people aged ≥65 years with mild cognitive impairment or dementia. The survival status was assessed based on the response of participants or their close relatives via a postal survey. Potential predictors including demographic and lifestyle-related factors, functional status, and behavioral and psychological status were assessed at the first visit at the memory clinic. A backward stepwise Cox regression model was used to select predictors, and a predictive model was developed using a regression coefficient-based scoring approach. The discrimination and calibration were assessed via Harrell's C-statistic and a calibration plot, respectively. RESULTS: A total of 2610 patients aged ≥65 years (men, 38.3%) were analyzed. Over a mean follow-up of 4.1 years, 544 patients (20.8%) died. Nine predictors were selected from the sociodemographic and clinical variables: age, sex, body mass index, gait performance, physical activity, and ability for instrumental activities of daily living, cognitive function, and self-reported comorbidities (pulmonary disease and diabetes). The model showed good discrimination and calibration for 1-5-year mortality (Harrell's C-statistic, 0.739-0.779). Some predictors were specifically associated with cause-specific mortality. CONCLUSIONS: This predictive model has good discriminative ability for 1- to 5-year mortality and can be easily implemented for people with mild cognitive impairment and all stages of dementia referred to a memory clinic.

RESUMO

BACKGROUND: The spread of the novel severe acute respiratory syndrome coronavirus 2 infection has been prolonged, with the highly contagious Omicron variant becoming the predominant variant by 2022. Many patients admitted to dedicated coronavirus disease 2019 (COVID-19) wards (COVID-19 treatment units) develop disuse syndrome while being treated in the hospital, and their ability to perform activities of daily living declines, making it difficult for hospitals to discharge them. This study aimed to investigate the relationship between the degree of frailty and home discharge of patients admitted to a COVID-19 treatment units. METHODS: This study retrospectively examined the in-patient medical records of 138 patients (82.7 ± 7.6 years old) admitted to a COVID-19 treatment unit from January to December 2022. The end-point was to determine the patients' ability to be discharged from the unit directly to home; such patients were classified into the 'Home discharge' group and compared with those in the 'Difficulty in discharge' group. The degree of frailty was determined based on the Clinical Frailty Scale (CFS), and the relationship with the endpoint was analysed. A receiver operating characteristic (ROC) curve was created and the cut-off value was calculated with the possibility of home discharge as the state variable and CFS as the test variable. Logistic regression analysis was conducted with the possibility of home discharge as the dependent variable and CFS as the independent variable. RESULTS: There were 75 patients in the Home discharge group and 63 in the Difficulty in discharge group. ROC analysis showed a CFS cut-off value of 6 or more, with a sensitivity of 70.7% and a specificity of 84.1%. The results of the logistic regression analysis showed a significant correlation between possibility of home discharge and CFS even after adjusting for covariates, with an odds ratio of 13.44. CONCLUSIONS: Based on the evaluation of the degree of frailty conducted in the COVID-19 treatment unit, it was possible to accurately predict whether a patient could be discharged directly to home after treatment CFS could be an effective screening tool to easily detect patients requiring ongoing hospitalisation even after the acute phase of treatment.

RESUMO

OBJECTIVE: To conduct an exploratory examination of caregiver burden involving toilet problems in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) and related characteristics. METHODS: We included 50 outpatients with amnestic MCI and AD and their caregivers. Patients were subclassified into three groups: MCI, mild AD, and moderate/severe AD. We used the Japanese version of the Zarit Burden Interview (J-ZBI) to evaluate caregiver burden and conducted a questionnaire on the frequency of lower urinary tract symptoms and related caregiver burden. We compared the frequency of questionnaire items with the level of burden in each group and subsequently determined the J-ZBI correlation coefficient. RESULTS: Among the questionnaire items, the caregiver's burden of "increased daytime urinary frequency," "nocturia," "urinary incontinence," and "they cannot clean the toilet" statistically significantly correlated with J-ZBI scores (ρ = 0.52, 0.65, 0.79, and 0.83, respectively). Items including "they cannot clean the toilet," "the smell of excrement is bothersome," "assistance for transfer is necessary," "they soil the clothes and bed," and "they cannot clean the genital region" were significantly more common in the patient group with moderate/severe AD. CONCLUSIONS: Lower urinary tract symptoms and toilet problems were significantly correlated with caregiver burden. Toilet problems differ depending on the severity of dementia. Therefore, a support system based on dementia severity is required to address toilet problems.

RESUMO

BACKGROUND: To determine how to maintain activity in persons with dementia and mild cognitive impairment, we examined the daily activity level by different degrees of clinical severity and sex differences in patients with Alzheimer's disease and mild cognitive impairment. METHODS: This study included 92 patients with Alzheimer's disease and 33 patients with mild cognitive impairment who visited our rehabilitation department. The Frenchay Activities Index was used to assess the level of activity. RESULTS: Women had high Frenchay Activities Index scores for household activities, such as meal preparation, washing clothes, and light housework, whereas men had high Frenchay Activities Index scores for social occasions and walking outside. Although activity decreased with the severity of dementia in women, there was no difference in men. Additionally, a negative correlation was observed between the number of people living together and activity in women. CONCLUSIONS: To maintain and improve activities in persons with Alzheimer's disease and mild cognitive impairment, it is important to suggest activities that fit the lifestyle of the individual and family caregivers and to provide lifestyle instructions that consider sex differences.

RESUMO

[Purpose] We investigated whether olfactory identification ability may be useful for early detection of cognitive decline. [Participants and Methods] The study included 55 community-dwelling older individuals without a history of mild cognitive impairment or dementia, who were capable of living independently. Cognitive function was evaluated using the Japanese versions of the Mini-Mental State Examination and the Montreal Cognitive Assessment tools. The olfactory identification ability was evaluated using the Odor Stick Identification Test for the Japanese. We also investigated the association between olfactory identification ability and cognitive function. [Results] Based on the Japanese version of the Mini-Mental State Examination, all participants were categorized into the noncognitive decline group, and based on the Japanese version of the Montreal Cognitive Assessment tool, 21 participants were categorized into the cognitive decline group. With regard to olfactory discrimination ability, we observed a significant difference between participants with and without cognitive decline based on the Japanese version of the Montreal Cognitive Assessment scores. Furthermore, we observed a significant positive correlation between the Japanese version of the the Montreal Cognitive Assessment scores and the Odor Stick Identification Test for the Japanese scores, although no significant correlation was observed between the Japanese version of the Mini-Mental State Examination and the Odor Stick Identification Test for the Japanese scores. [Conclusion] Olfactory identification ability may be useful to detect early-stage cognitive decline in community-dwelling older individuals.

RESUMO

[Purpose] To examine the olfactory identification abilities and specify the difficult-to-identify odors in community-dwelling individuals with mild cognitive impairment (MCI) and Alzheimer's disease (AD). [Participants and Methods] We included, 12 and 17 patients with MCI (MCI group) and AD (AD group), respectively, and 30 community-dwelling older adults with no history of MCI or a dementia diagnosis (control group). Scores on the Japanese odor stick identification test (OSIT-J), an olfactory identification ability test, were compared among the three groups with intergroup differences examined accordingly. Next, we performed intergroup comparisons of the ratios of correct responses for each odor, and the difficult-to-identify odors were examined. [Results] OSIT-J scores of the MCI and AD groups were significantly lower than those of the control group. There were no intergroup differences in the correct identification of pungent odors. No patients in the AD group could identify the odor of cooking gas. The ability to identify food-related odors was reduced in the MCI and AD groups. [Conclusion] Patients with MCI and AD had reduced olfactory identification abilities in comparison to community-dwelling older adults without cognitive decline. These findings suggest the importance of olfactory evaluation before providing patients with dementia with therapeutic interventions associated with olfactory stimuli.

RESUMO

BACKGROUND: The cube-copying test is used to assess cognitive function. It is one of the methods used to distinguish healthy older individuals from those with cognitive impairment based on its 3 mm vertex criterion and parallel line errors. We sought to assess how: (1) precisely elderly community-dwelling individuals draw cubes based on two different vertex criteria; and (2) they keep the parallelism of lines. METHODS: The cross-sectional design study population comprised 121 adults ((outlier analysis excluded the results of three, resulting in 118 participants) ≥ 65 years (21 men and 100 women) who participated in an annual physical fitness circuit and who lived independently in their communities. We recorded the participants' ages, years of education, and the scores they obtained in the Japanese version of the Montreal Cognitive Assessment. Participants were instructed to draw the cube as precisely as possible. Cube drawings were assessed based on the correct position of the vertices using 1 and 3 mm criteria and parallel line errors. RESULTS: Eighty-nine percent of the participants were able to draw vertices within 3 mm distance from the correct position but found it difficult to draw them within 1 mm distance. Using the 3 mm vertex criterion, the mean score for correct vertices was six (out of a maximum of eight). Most of the participants made a maximum of one out of six possible parallel line errors. CONCLUSIONS: Almost 90% of the elderly in our study drew the vertices within 3 mm of the correct position, and the parallel line errors were few. The 3 mm vertex and parallel line criteria by cube-copying seem to be cleared by most community-dwelling elderly. Further research should determine if participants aged ≥85 years with less than 6 years of education show different results.

RESUMO

BACKGROUND: Aphasia often appears in persons living with dementia; however, aphasia and the mirror phenomenon are rarely present at the same time. CASE PRESENTATION: Here, we report a case of fluent conversation with a person in a mirror or a magazine, and examine the underlying mechanism using brain imaging and neuropsychological findings. We found that the appearance of the mirror phenomenon may be associated with a visuospatial dysfunction caused by a decreased function of the posterior region of the right temporal and parietal lobe. Moreover, active talking to a person in a mirror or a person in a magazine could be associated with disinhibition caused by a decline in bilateral frontal lobe function. CONCLUSIONS: This case represents a very valuable and interesting presentation because it is the first report of a long-term follow-up of the course of dementia using neurological imaging, and of the neuropsychological analysis of the mechanism of conversation with a mirror image combined with aphasia.

RESUMO

PURPOSE OF REVIEW: When the thalamus is damaged, not only are there neurological symptoms such as sensory impairment, hemianopia, or motor control disorders, but there are also various neuropsychological symptoms. We discuss the basic anatomy and function of the thalamus followed by a discussion of thalamic aphasia and hemineglect. RECENT FINDINGS: Subcortical lesions in patients with hemineglect involved the anatomical network directly linked to the superior temporal gyrus. Furthermore, the pulvinar, part of the thalamus, may be associated with hemineglect. General linguistic tasks activated the thalami, depending on the difficulty, as well as the frontal and temporal lobes. The thalamus may play a role in language and be involved in the activation of cortical language areas, and in the linguistic integration function via verbal memory and semantic mechanisms. Thalamic lesions are associated with aphasia and hemineglect. It is possible the mechanisms and such neuropsychological may be different depending on the size and site of the thalamic lesion.

RESUMO

Thalamic hemorrhages are associated with a variety of cognitive dysfunctions, and it is well known that such cognitive changes constitute a limiting factor of recovery of the activities of daily living (ADL). The relationship between cognitive dysfunction and hematomas is unclear. In this study, we investigated the relationship between aphasia/neglect and hematoma volume, hematoma type, and the ADL. One hundred fifteen patients with thalamic hemorrhage (70 men and 45 women) were studied. Their mean age was 68.9 ± 10.3 years, and patients with both left and right lesions were included. We calculated hematoma volume and examined the presence or absence of aphasia/neglect and the relationships between these dysfunctions and hematoma volume, hematoma type, and the ADL. Fifty-nine patients were found to have aphasia and 35 were found to have neglect. Although there was no relationship between hematoma type and cognitive dysfunction, hematoma volume showed a correlation with the severity of cognitive dysfunction. The ADL score and ratio of patient discharge for patients with aphasia/neglect were lower than those for patients without aphasia/neglect. We observed a correlation between the hematoma volume in thalamic hemorrhage and cognitive dysfunction. Aphasia/neglect is found frequently in patients with acute thalamic hemorrhage and may influence the ADL.

RESUMO

BACKGROUND: Cognitive disorders, such as memory disturbances, are often observed following a subarachnoid hemorrhage. We present a very rare case where rupture of a posterior cerebral artery aneurysm caused restricted damage to the hippocampus unilaterally, and caused memory disturbances. CASE PRESENTATION: A 56-year-old, right-handed man, with a formal education history of 16 years and company employees was admitted to our hospital because of a consciousness disturbance. He was diagnosed as having a subarachnoid hemorrhage due to a left posterior cerebral artery dissecting aneurysm, and coil embolization was performed. Subsequently, he had neither motor paresis nor sensory disturbances, but he showed disorientation, and both retrograde and anterograde amnesia. Although immediate recall and remote memory were almost intact, his recent memory was moderately impaired. Both verbal and non-verbal memories were impaired. Brain computed tomography (CT) and magnetic resonance imaging (MRI) revealed a cerebral hematoma in the left temporal lobe involving the hippocampus and parahippocampal gyrus, and single-photon emission computed tomography (SPECT) demonstrated low perfusion areas in the left medial temporal lobe. CONCLUSIONS: We suggest that the memory impairment was caused by local tissue destruction of Papez's circuit in the dominant hemisphere due to the cerebral hematoma.

RESUMO

OBJECTIVE: A high incidence of dysphagia is seen during the acute phase of cerebral haemorrhage; however, there have been only rare reports of dysphagia caused by thalamic haemorrhage. We studied cases of thalamic haemorrhage during the acute period after hospitalization and examined the relationships between the frequency of dysphagia, stroke focus and haematoma volume. METHODS: There were 113 subjects in this study, selected from 247 patients with thalamic haemorrhage who visited our rehabilitation centre. Patients were excluded if they had a history of dementia, stroke, confusion, epileptic seizure, surgical treatment or tracheotomy. We conducted a bedside swallowing assessment (BSA) by using the repetitive saliva swallowing test and modified water swallowing test. The relationships between oral intake condition at the time of hospital discharge, discharge destination (e.g. home), type of haematoma and haematoma volume were examined. RESULTS: Abnormal BSA was found in 55% of the subjects (n = 62) with thalamic haemorrhage. Existence of a swallowing disorder was related to haematoma type and haematoma volume. A regular diet was possible in 41% of the subjects (n = 46). Age, haematoma volume, initial BSA evaluation and cognitive function had the greatest influence on a subject's ability to eat a general diet at the time of hospital discharge. Of those subjects in whom the initial BSA evaluation was normal, 70% were able to eat a regular diet at discharge. However, of those in whom the BSA evaluation was abnormal, >70% were discharged with enteral feeding. Furthermore, the rates of discharge to home were 95% in patients who could eat a regular diet and 30% in patients who needed enteral feeding. CONCLUSIONS: In the acute phase of thalamic haemorrhage, dysphagia was found in a high percentage of subjects. Dysphagia is associated with a poor prognosis for early hospital discharge.

RESUMO

Causative factors for pneumonia and their impact on prognosis were investigated in patients with acute ischemic stroke. Patient characteristics, swallowing function, lesions, and the presence or absence of intervention by dysphagia rehabilitation were assessed in 292 patients with acute cerebral infarction to determine the association of these factors with pneumonia. As a result, 52 patients (17.8%) experienced pneumonia. Of these, 14 developed pneumonia within 3 days of hospital admission and 38 developed the disease after 4 days or later. Pneumonia was frequently seen among elderly patients, those with severe neurological symptoms or cognitive disorders and those with bilateral multiple lesions, and was associated with prolonged length of stay and decline in activities of daily living at hospital discharge. In conclusion, elderly age, bilateral lesions, and severe neurological deficit were significantly associated with pneumonia. Pneumonia in turn strongly predicted inability to take food orally and be discharged from hospital to home.

RESUMO

We report the case of a 68-year-old right-handed man who was admitted to our hospital because of sudden onset of headache. On admission, he presented with left homonymous hemianopsia, disorientation, and recent memory disturbance; however, he had normal remote memory and digit span. He was able to recall the room layout of his house and describe the route from the nearest station to his home on a map. However, at the hospital, he sometimes lost his way because of amnesia. Computed tomography (CT) and magnetic resonance imaging revealed a subcortical hematoma in the right occipital forceps and the parietal lobe, involving the cingulate isthmus. Single-photon emission CT imaging showed reduced perfusion not only in the retrosplenial region but also in the right thalamus. These findings suggested that the retrosplenial amnesia might have been caused by the interruption of hippocampal input into the anterior thalamus.

RESUMO

BACKGROUND: Approximately one-half of all patients with acute intracerebral hemorrhage (ICH) develop dysphagia that can lead to pneumonia or fatal outcomes; however, there are no reports about the relationship between swallowing function and cerebral microbleeds (CMBs) in these patients. Therefore, we investigated whether CMBs were associated with dysphagia in patients with ICH. METHODS: A total of 100 patients (mean age, 65.1 ± 14.1 years; range, 36-95 years) with acute supratentorial ICH were included in this study. CMBs were detected on T2*-weighted magnetic resonance imaging performed during admission using a 1.5-T scanner (mean duration from onset to magnetic resonance imaging, 12.6 ± 8.4 days). We assessed swallowing function by using bedside swallowing assessments on admission and by monitoring the mode of nutritional intake at discharge in relation to the number and location of CMBs. RESULTS: CMBs were detected in 60 of the 100 patients (60%) and were related to dysphagia. The number of CMBs and dysphagia were not related, but a significant relationship was observed in the presence of bilateral hematomas and CMBs. CONCLUSIONS: In addition to assessing just the presence or absence of CMBs, clinicians should identify the presence of bilateral or deep lesions in patients with ICH from the perspective of swallowing dysfunction.

RESUMO

PURPOSE: Cognitive dysfunctions with stroke of the brain stem are rare. We focused on and examined cognitive dysfunction after pontine hemorrhages. OBJECT AND METHOD: After July 2008, we treated 23 patients with pontine hemorrhages. Only 10 patients were included, all other patients had old hemorrhages, venous anomalies, and disturbances of consciousness. The patients included six men and four women, aged 51 years to 86 years old. The volume of hematoma was 0.11-5.20mL(average:1.74mL);there were six right side, two left side, two bilateral, three ventral, and seven dorsal hematomas. We performed neuropsychological tests such as mini-mental state examination(MMSE), Raven's coloured progressive matrices(RCPM), and frontal assessment battery(FAB). RESULT: Eight cases had an abnormal score on the tests. The volume of hematoma showed a high negative correlation with MMSE scores(p=0.0194)and RCPM(p=0.0338). On the other hand, the volume of hematoma and FAB scores(p=0.0832)were uncorrelated, and the localization of the hematoma did not correlate with tests of cognitive function. CONCLUSION: Cognitive dysfunction is not rare after pontine hemorrhage. Therefore, for patients with infratentorial lesions, it is necessary to perform detailed cognitive functional tests.

RESUMO

AIM: This study aimed to investigate the assessment tools dementia specialists use in clinical practice, reasons for their use and assessment-related factors. METHODS: A questionnaire survey was carried out from 15 September 2021 to 20 October 2021 among 1858 dementia specialists in Japan, with responses obtained via mail or using a Web form accessed via a Web address. RESULTS: Of the 1858 specialists who were sent the questionnaire, 574 responded, yielding a response rate of 32.2%. Almost all respondents stated that the main purposes of neuropsychological testing were to identify the pathophysiology and aid diagnosis. Most respondents identified behavioral and psychological symptoms of dementia as important factors for assessment. The most commonly used tests were the Hasegawa Dementia Scale-Revised and Mini-Mental State Examination, often used as screening tools. The Mini-Mental State Examination, Clock Drawing Test and Cube Copying Test were common assessments carried out directly by specialists. Quality of life and burden of care were less commonly assessed. CONCLUSIONS: Despite the main purpose of carrying out neuropsychological tests on dementia patients is to "understand the pathophysiology" and "aid in diagnosis," many assessment methods were chosen as screening methods carried out in a short time during clinic hours. The lack of evaluation of care burden and QOL, considered important by specialists, is an issue for the future in treating people with dementia, a life disability.

RESUMO

Objectives: To predict falls by adding an adherence assessment to a static balance ability assessment, and to evaluate fall prediction accuracy. Methods: This study included 416 patients who were admitted to a 45-bed convalescent rehabilitation ward over a 2-year period. The patients were assessed at the time of admission using the Standing Test for Imbalance and Disequilibrium (SIDE) and three additional, newly developed adherence items. Patients were divided into two groups: a group that experienced falls (fall group) and a group that did not experience falls (non-fall group) within 14 days of admission. The sensitivity and specificity of the assessment items for predicting falls were calculated. Results: Sensitivity was 0.86 and specificity was 0.42 when the cutoff was between SIDE levels 0-2a and 2b-4. Combining balance assessment using the SIDE with the memory and instruction adherence items improved fall prediction accuracy such that the sensitivity was 0.75 and the specificity was 0.64. Conclusions: Our analysis suggested that adherence assessment can improve fall risk prediction accuracy.

RESUMO

BACKGROUND: Non-pharmacological interventions effective for depressive mood and bilateral relationships among persons with cognitive impairment (PwCI) and their family caregivers (FCGs) have not been established. OBJECTIVE: To examine the feasibility of a newly developed group-based art appreciation and self-expression program (NCGG-ART) for dyads of PwCI and their FCGs. METHODS: This pilot randomized control trial included 34 dyads of PwCI diagnosed with mild to moderate Alzheimer's disease or mild cognitive impairment, and their FCGs, from an outpatient rehabilitation service (Holistic Physio-Cognitive Rehabilitation [HPCR]). Participants were randomly divided equally into the HPCR (control group) or NCGG-ART and HPCR (intervention group) groups. Both included 1-hour weekly, 6-week programs. The primary outcome was depressive symptoms among FCGs assessed using the Patient Health Questionnaire-9 (PHQ-9). Feasibility outcomes included participant satisfaction and motivation. FCGs were interviewed about their experiences and feelings regarding the program, which were analyzed using content analysis. RESULTS: Thirty-two dyads (intervention group:16; control group:16) completed the study period. High participation rates, satisfaction, and motivation were demonstrated throughout the intervention. Scores in the PHQ-9 among FCGs did not show positive effects: mean changes in the score were 1.3 for the intervention group and -0.8 for the control group (Cohen d:0.56). However, the qualitative analysis revealed favorable experiences and feelings of the FCGs, such as positive emotions, social interactions, and person-centered attitudes to and positive relationships with PwCI. CONCLUSIONS: This program demonstrated high feasibility with FCGs' favorable responses to emotions and relationships with PwCI, ensuring future investigations with a confirmatory study design.

RESUMO

Background: Interventions and care that can evoke positive emotions and reduce apathy or agitation are important for people with dementia. In recent years, socially assistive robots used for better dementia care have been found to be feasible. However, the immediate responses of people with dementia when they are given multiple sensory modalities from socially assistive robots have not yet been sufficiently elucidated. Objective: This study aimed to quantitatively examine the immediate emotional responses of people with dementia to stimuli presented by socially assistive robots using facial expression analysis in order to determine whether they elicited positive emotions. Methods: This pilot study adopted a single-arm interventional design. Socially assistive robots were presented to nursing home residents in a three-step procedure: (1) the robot was placed in front of participants (visual stimulus), (2) the robot was manipulated to produce sound (visual and auditory stimuli), and (3) participants held the robot in their hands (visual, auditory, and tactile stimuli). Expression intensity values for "happy," "sad," "angry," "surprised," "scared," and "disgusted" were calculated continuously using facial expression analysis with FaceReader. Additionally, self-reported feelings were assessed using a 5-point Likert scale. In addition to the comparison between the subjective and objective emotional assessments, expression intensity values were compared across the aforementioned 3 stimuli patterns within each session. Finally, the expression intensity value for "happy" was compared between the different types of robots. Results: A total of 29 participants (mean age 88.7, SD 6.2 years; n=27 female; Japanese version of Mini-Mental State Examination mean score 18.2, SD 5.1) were recruited. The expression intensity value for "happy" was the largest in both the subjective and objective assessments and increased significantly when all sensory modalities (visual, auditory, and tactile) were presented (median expression intensity 0.21, IQR 0.09-0.35) compared to the other 2 patterns (visual alone: median expression intensity 0.10, IQR 0.03-0.22; P<.001; visual and auditory: median expression intensity 0.10, IQR 0.04-0.23; P<.001). The comparison of different types of robots revealed a significant increase when all stimuli were presented by doll-type and animal-type robots, but not humanoid-type robots. Conclusions: By quantifying the emotional responses of people with dementia, this study highlighted that socially assistive robots may be more effective in eliciting positive emotions when multiple sensory stimuli, including tactile stimuli, are involved. More studies, including randomized controlled trials, are required to further explore the effectiveness of using socially assistive robots in dementia care.
