Authors: Minuljo Tania Tedjo , Gasem Muhammad Hussein , Hadi Purnomo
Published: August 2017

Background: Active Cytomegalovirus (CMV) infection has long been related to immunocompromised conditions such as malignancy, HIV-AIDS, longterm use of corticosteroids and organ transplantation. Nowadays, several studies showed that active CMV infection also frequently found in formerly immunocompetent patients during critically ill condition. Alteration of immune system in critically ill condition might become the most possible reason enderlying this adverse event.Aim: To document the prevalence of active CMV infection in critically ill immunocompetent patient admitted to ICU and to find out the difference of the disease severity between group of patients with and without active CMV infection.Method: This was a cross sectional study. Study conducted from April 1st - June 30th 2013. Subjects were patient aged ≥14 years, hospitalized in the ICU of Dr. Kariadi Hospital, Semarang, Indonesia. Patients who had history of malignancy, HIV-AIDS, use of corticosteroids and organ transplatation were excluded from the study. Disease severity was calculated using APACHE II score in the first 24 hours of ICU admission. EDTA sample for qualitative PCR examination (procedure as described elsewhere) collected after 4 days of ICU admission. Primer for CMV were as follow CMV-F: CATGAAGGTCTTTGCCCAGTAC, CMV-R: GGCCAAAGTGTAGGCTACAATAG. Datas were analyzed using bivariate analysis.Result: Active CMV infection was detected in 16 out of 50 subjects. Mean score of disease severity in all subjects (based on APACHE II scoring system) was 11.8±6.43. Mean score of disease severity in group with active CMV infection was higher than group without active CMV infection, but not differ significantly (12.75 vs. 11.47; p=0,510).Conclusion: The prevalence of active CMV infection in critically ill immunocompetent patient is relatively high (16/50; 32%) in the ICU of Dr. Kariadi Hospital, Semarang, Indonesia. Degree of disease severity might influence the occurance of CMV infection. Qualitative PCR testing was an aqurate tool for diagnosing active CMV infection.

Owing to the increasing demand for rehabilitation services, robotics have been engaged in addressing the drawbacks of conventional rehabilitation therapy. This paper focuses on the modelling and control of a three-link lower limb exoskeleton for gait rehabilitation that is restricted to the sagittal plane. The exoskeleton that is modelled together with a human lower limb model is subjected to a number of excitations at its joints while performing a joint space trajectory tracking, to investigate the effectiveness of the proposed controller in compensating disturbances. A particle swarm optimised active force control strategy is proposed to facilitate disturbance rejection of a conventional proportional-derivative (PD) control algorithm. The simulation study provides considerable insight into the robustness of the proposed method in attenuating the disturbance effect as compared to the conventional PD counterpart without compromising its tracking performance. The findings from the study further suggest its potential employment on a lower limb exoskeleton.

Published: August 2017

Background:

Considering the role of different ethnical, cultural and geographical factors in health related quality of life (HRQOL) as well as the perception of different populations regarding various weight disorders, we aimed to evaluate the association between body mass index (BMI) and HRQOL in Iranian children and adolescents.

Methods:

This cross-sectional study was part of the Weight Disorders Survey of the CASPIAN-IV study. During this study, students aged 6–18 years from urban and rural areas of 30 provinces of Iran were selected. HRQOL of the students was evaluated by using the Persian version of the Pediatric Quality of Life inventory (PedsQL™ 4.0™ 4.0) Generic Core Scales. The mean of total HRQOL and its subscales were compared in underweight, normal weight, overweight and obese students.

Results:

The mean of total HRQOL, physical functioning and psychological functioning scores in the total population were 83.31, 84.25 and 82.79, respectively. The mean of the total HRQOL score and the psychosocial score were significantly lower in underweight students aged 6–12 years than in other groups (p<0.05). The mean of the total HRQOL score and psychosocial score were significantly lower in obese students aged 13–18 years than in other groups (p<0.05). Overweight and obesity was negatively associated with total HRQOL, psychosocial and school functioning subscales (p<0.05). There was a significant negative association between emotional functioning and obesity (p<0.05).

Conclusions:

The findings or this study support the importance of personal perception and cultural norm roles in HRQOL. Given the association between weight disorders and psychosocial health, it is suggested that social and cultural factors have a more crucial role in the HRQOL of children and adolescents.

Published: August 2017

Background:

Hyperparathyroidism (HPT) is a rare disease in the pediatric population, and optimal management may be unclear if it is due to an occult parathyroid adenoma. We present a case report of a pediatric patient with an occult, ectopic, supernumerary, parathyroid adenoma.

Case presentation:

A 13-year-old female who initially presented with anxiety was diagnosed with HPT. Preoperative imaging and bilateral neck exploration with four-gland biopsy were negative for any parathyroid adenoma. Postoperative MRI identified a thymic mass. She subsequently underwent video-assisted thoracoscopic thymectomy with resection of an intrathymic parathyroid adenoma.

Conclusions:

The diagnosis of pediatric HPT is increasing. Supernumerary or occult parathyroid adenomas are rare and add complexity to presurgical planning and management. Our case represents the rare occurrence of a pediatric ectopic supernumerary occult parathyroid adenoma treated with a two-stage approach utilizing multiple imaging studies. We provide a review of the pathology and propose an algorithmic approach to manage these complex patients.

Published: August 2017

This paper quantitatively investigates the effect of transportation system on trade flows of four major port cities in China. Due to the significant country-pair heterogeneities in both intercept and slope terms, this paper introduced a random-coefficients model for parameters estimation. The empirical findings imply that the impact of the explanatory variables included in the gravity equation could be inaccurately estimated if the pair-wise heterogeneity biases in both intercept and slope terms are not accounted for during the econometric estimation of the model. In particular, in the presence of this heterogeneity, parameter estimates tend to be underestimated for country-pairs with higher trade volume and overestimated for those country-pairs with lower trade volume. In addition, the empirical results suggest that the improvement transportation system in port cities of China offers greater scope for its trade competitiveness.

Published: August 2017

Cyclization of 2-(2-hydroxyethyl)phenol via DMC chemistry in acidic conditions is herein discussed for the first time. Reaction conditions have been investigated and optimized. This substrate is quite appealing as it incorporates a 2-hydroxyethyl moiety in ortho to the aromatic hydroxyl group capable of stabilizing the related phenonium ion. When the reaction mechanism was investigated via theoretical calculations, the results suggest that the most favorable pathway encompasses a DMC-mediated formation of the phenonium ion that is converted into the 2-(2-methoxyethyl)phenol. The related cyclic ether is then formed via intramolecular cyclization of this intermediate. This peculiar cyclization reaction is another example of the versatility of DMC herein used as solvent, methoxycarbonylation agent and leaving group in the intramolecular cyclization leading to the phenonium ion.
Evaluation of stearic acid modified industrial lime sludge waste as a filler in high density polyethylene composites
Authors: Kashyap Satadru , Datta Dilip
Published: August 2017

Industrial lime sludge (LS), an environmental hazard, is surface modified by stearic acid (SA) in order to reinforce high density polyethylene (HDPE) composites. Uncoated and SA-coated LS-reinforced HDPE composites are prepared and their mechanical, thermal, and morphological properties are studied and compared with each other. FTIR spectroscopy revealed successful grafting of SA onto LS particles while SEM morphology showed that SA coating hinders particle agglomeration in the HDPE matrix at higher filler loading. Mechanical properties such as tensile and flexural strength and modulus, elongation at break, and impact strength increased significantly for SA-coated LS composites due to uniform particle dispersion and effective filler-matrix interfacial interaction. The SA coating increased the entanglement at the filler-matrix interface thereby increasing the thermal decomposition of the coated composites from 500°C to 600°C. Additionally, it also reduced the water absorption rate of the coated composites in comparison with its uncoated counterpart. Thus, SA proves to be an efficient surface modifier for LS to produce HDPE composites with superior properties at a low cost. Needless to say, this study also suggests an alternative LS waste management route which offers benefits of reusing an industrial waste, decreasing the pollution, and developing fresh polymeric products.
Working Memory Replay Prioritizes Weakly Attended Events
Authors: Jafarpour Anna , Penny Will , Barnes Gareth , Knight Robert T. , Duzel Emrah
Published: August 2017

One view of working memory posits that maintaining a series of events requires their sequential and equal mnemonic replay. Another view is that the content of working memory maintenance is prioritized by attention. We decoded the dynamics for retaining a sequence of items using magnetoencephalography, wherein participants encoded sequences of three stimuli depicting a face, a manufactured object, or a natural item and maintained them in working memory for 5000 ms. Memory for sequence position and stimulus details were probed at the end of the maintenance period. Decoding of brain activity revealed that one of the three stimuli dominated maintenance independent of its sequence position or category; and memory was enhanced for the selectively replayed stimulus. Analysis of event-related responses during the encoding of the sequence showed that the selectively replayed stimuli were determined by the degree of attention at encoding. The selectively replayed stimuli had the weakest initial encoding indexed by weaker visual attention signals at encoding. These findings do not rule out sequential mnemonic replay but reveal that attention influences the content of working memory maintenance by prioritizing replay of weakly encoded events. We propose that the prioritization of weakly encoded stimuli protects them from interference during the maintenance period, whereas the more strongly encoded stimuli can be retrieved from long-term memory at the end of the delay period.

Vertebrate hearing organs manifest cellular asymmetries across the radial axis that underlie afferent versus efferent circuits between the inner ear and the brain. Therefore, understanding the molecular control of patterning across this axis has important functional implications. Radial axis patterning begins before the cells become postmitotic and is likely linked to the onset of asymmetric expression of secreted factors adjacent to the sensory primordium. This study explores one such asymmetrically expressed gene,Wnt9a, which becomes restricted to the neural edge of the avian auditory organ, the basilar papilla, by embryonic day 5 (E5). Radial patterning is disrupted whenWnt9ais overexpressed throughout the prosensory domain beginning on E3. Sexes were pooled for analysis and sex differences were not studied. Analysis of gene expression and afferent innervation on E6 suggests that ectopic Wnt9a expands the neural-side fate, possibly by re-specifying the abneural fate. RNA sequencing reveals quantitative changes, not only in Wnt-pathway genes, but also in genes involved in axon guidance and cytoskeletal remodeling. By E18, these early patterning effects are manifest as profound changes in cell fates [short hair cells (HCs) are missing], ribbon synapse numbers, outward ionic currents, and efferent innervation. These observations suggest that Wnt9a may be one of the molecules responsible for breaking symmetry across the radial axis of the avian auditory organ. Indirectly, Wnt9a can regulate the mature phenotype whereby afferent axons predominantly innervate neural-side tall HCs, resulting in more ribbon synapses per HC compared with abneural-side short HCs with few ribbons and large efferent synapses.

SIGNIFICANCE STATEMENTWnts are a class of secreted factors that are best known for stimulating cell division in development and cancer. However, in certain contexts during development, Wnt-expressing cells can direct neighboring cells to take on specific fates. This study suggests that the Wnt9a ligand may play such a role in the developing hearing organ of the bird cochlea. This was shown through patterning defects that occur in response to the overexpression of Wnt9a. This manipulation increased one type of sensory hair cell (tall HCs) at the expense of another (short HCs) that is usually located furthest from the Wnt9a source. The extraneous tall HCs that replaced short HCs showed some physiological properties and neuronal connections consistent with a fate switch.
Human Occipital and Parietal GABA Selectively Influence Visual Perception of Orientation and Size
Authors: Song Chen , Sandberg Kristian , Andersen Lau Møller , Blicher Jakob Udby , Rees Geraint
Published: August 2017

GABA is the primary inhibitory neurotransmitter in human brain. The level of GABA varies substantially across individuals, and this variability is associated with interindividual differences in visual perception. However, it remains unclear whether the association between GABA level and visual perception reflects a general influence of visual inhibition or whether the GABA levels of different cortical regions selectively influence perception of different visual features. To address this, we studied how the GABA levels of parietal and occipital cortices related to interindividual differences in size, orientation, and brightness perception. We used visual contextual illusion as a perceptual assay since the illusion dissociates perceptual content from stimulus content and the magnitude of the illusion reflects the effect of visual inhibition. Across individuals, we observed selective correlations between the level of GABA and the magnitude of contextual illusion. Specifically, parietal GABA level correlated with size illusion magnitude but not with orientation or brightness illusion magnitude; in contrast, occipital GABA level correlated with orientation illusion magnitude but not with size or brightness illusion magnitude. Our findings reveal a region- and feature-dependent influence of GABA level on human visual perception. Parietal and occipital cortices contain, respectively, topographic maps of size and orientation preference in which neural responses to stimulus sizes and stimulus orientations are modulated by intraregional lateral connections. We propose that these lateral connections may underlie the selective influence of GABA on visual perception.

SIGNIFICANCE STATEMENTGABA, the primary inhibitory neurotransmitter in human visual system, varies substantially across individuals. This interindividual variability in GABA level is linked to interindividual differences in many aspects of visual perception. However, the widespread influence of GABA raises the question of whether interindividual variability in GABA reflects an overall variability in visual inhibition and has a general influence on visual perception or whether the GABA levels of different cortical regions have selective influence on perception of different visual features. Here we report a region- and feature-dependent influence of GABA level on human visual perception. Our findings suggest that GABA level of a cortical region selectively influences perception of visual features that are topographically mapped in this region through intraregional lateral connections.

Searching for Ideas in Working up a Visual Image
Authors: Sharrock Wes , Greiffenhagen Christian
Published: August 2017

The empirical basis of this study is the examination of audio and video records of a screen-focussed classroom activity that involved the use of a newly developed software system designed to enable understanding of and reflection on literary works through the depiction of those works in the form of an on-screen storyboard. The central attention is on the way in which two pupils compose, in collaboration, an additional image for their shared storyboard, showing how their task coordination involves their verbal and gestural activities as centred upon the use of the on-screen image forming resources supplied by the software system. The analysis is connected to general arguments about the debated issue of ‘emergence’ in social science literature by proposing an ethnomethodological treatment of emergence as something that is generated in and through the organisation of courses of action.
Psychophysiological Indices of Music-Evoked Emotions in Musicians

Published: August 2017

A number of psychophysiological measures indexing autonomic and somatovisceral activation to music have been proposed in line with the wider emotion literature. However, attempts to replicate experimental findings and provide converging evidence for music-evoked emotions through physiological changes, overt expression, and subjective measures have had mixed success. This may be due to issues in stimulus and participant selection. Therefore, the aim of Experiment 1 was to select musical stimuli that were controlled for instrumentation, musical form, style, and familiarity. We collected a wide range of subjective responses from 30 highly trained musicians to music varying along the affective dimensions of arousal and valence. Experiment 2 examined a set of psychophysiological correlates of emotion in 20 different musicians by measuring heart rate, skin conductance, and facial electromyography during listening without requiring behavioral reports. Excerpts rated higher in arousal in Experiment 1 elicited larger cardiovascular and electrodermal responses. Excerpts rated positively in valence produced higher zygomaticus major activity, whereas excerpts rated negatively in valence produced higher corrugator supercilii activity. These findings provide converging evidence of emotion induction during music listening in musicians via subjective self-reports and psychophysiological measures, and further, that such responses are similar to emotions observed outside the musical domain.
Fighting tubulin-targeting anticancer drug toxicity and resistance
Authors: Visconti Roberta , Grieco Domenico
Published: August 2017

Tubulin-targeting drugs, like taxanes and vinca alkaloids, are among the most effective anticancer therapeutics used in the clinic today. Specifically, anti-microtubule cancer drugs (AMCDs) have proven to be effective in the treatment of castration-resistant prostate cancer and triple-negative breast cancer. AMCDs, however, have limiting toxicities that include neutropenia and neurotoxicity, and, in addition, tumor cells can become resistant to the drugs after long-term use. Co-targeting mitotic progression/slippage with inhibition of the protein kinases WEE1 and MYT1 that regulate CDK1 kinase activity may improve AMCD efficacy, reducing the acquisition of resistance by the tumor and side effects from the drug and/or its vehicle. Other possible treatments that improve outcomes in the clinic for these two drug-resistant cancers, including new formulations of the AMCDs and pursuing different molecular targets, will be discussed.

Welsh English intonation and social identity
Authors: Shevchenko Tatyana , Buraya Elena , Fedotova Maria , Sadovnikova Natalia
Published: August 2017

This paper is a sociophonetic study concerned with state-of-the-art description of Welsh English (WE) pitch patterns which may serve as WE regional and social markers. WE pitch patterns in authentic spontaneous conversations are correlated with social factors of regional and cultural background (North Wales, South Wales, Cardiff), generation of speakers (young, middle-aged, old), gender (men, women) and social class (middle, working). The data are compared to Received Pronunciation (RP) tone nomenclature (Crystal, 1969) in search of systemic (i.e. concerned with the total repertoire of tones in each variety), distributional and realisational differences. Within the identical tone systems a considerable difference in the distribution of certain WE pitch configurations is interpreted as the impact of the Welsh language. The data are further specified to the dominant pattern frequency in each region, age, gender and social class. Special reference is made to the acoustic structure of rise-falls in North Wales, which is a new subject of research.
A matched-guise study on L2, heritage, and native Spanish speakers’ attitudes to Spanish in the State of Washington
Authors: Fernández-Mallat Víctor , Carey Max
Published: August 2017

By means of a matched-guise study, this paper examines the attitudes of L2, heritage, and native Spanish speakers in the state of Washington toward Mexican-accented and English-accented Spanish. We interpret our findings in the wake of previous research on language attitudes and ideologies related to Spanish in the United States which shows that Spanish and those who speak it as a first or heritage language are thought to have a lower socioeconomic status than English and Anglophones. 97 Spanish-speaking participants residing in Washington (N=95) and the Pacific Northwest (N=2) rated 4 voices along six-point semantic differential scales falling into the dimensions of superiority, solidarity, language competence, and physical characteristics. We submitted mean scores to a linear mixed-effects model. Contrary to our expectations, all groups rated the Mexican-accented guises higher than the English-accented guises in the dimension of superiority. Also unforeseen, the L2 speakers rated the Mexican-accented voices higher in the dimension of solidarity. We consider the high level of education of the respondents and, for the L2 subjects, their experience as advanced Spanish language speakers, as likely explanations for the observed attenuation of well-documented prevailing stereotypes directed at Latinos from the monolingual community at large.

Modern Hebrew (MH) presents an interesting case of a national language whose crystallisation involved not only intensive planning, but also unplanned processes of stratification, which has resulted in a continuous reevaluation and reallocation of existing features. The role of nonclassical inherited elements in this progression is revealing, as they emblematise popular ‘authentic’ usage on the one hand and diasporic (i.e. nonnative) premodern being on the other, thus exposing the tension between standard and nonstandard language. This study examines the stylistic status of two such elements, be'im ‘if’ and bixde ‘for’, ‘in order’, in two major phases in the short history of MH, in order to characterise the prescriptive discourse of MH and its national undertones.

Desde o momento em que as empresas disponibilizam uma vaga, os candidatos começam a trabalhar no gerenciamento de impressão, que nada mais é do que o candidato se transformar em um produto, em que ele aprende a mostrar para a empresa, o que a empresa quer ver, ou seja, vira um gestor da própria imagem. Deste modo, o estudo discutiu o seguinte problema de pesquisa: como o gerenciamento de impressão auxilia o comportamento dos candidatos a vagas em instituições financeiras, na percepção dos gerentes de agência. Tendo assim como objetivo analisar como o gerenciamento de impressão auxilia o comportamento de candidatos a vagas em instituições financeiras, na percepção dos gerentes de agências bancárias. Apoiou-se nos seguintes objetivos específicos: Identificar os traços de personalidade dos colaboradores escolhidos pelas empresas na percepção dos gerentes;verificar como funciona o processo de recrutamento e seleção em instituições financeiras e apontar as formas de gerenciamento de impressão utilizadas pelos candidatos a vagas em instituições financeiras na percepção dos gerentes. A justificativa da pesquisa baseou-se na concepção atual do mercado de trabalho, onde na visão dos candidatosé cada vez mais competitiva a busca pelo oficio perfeito, onde consiga segurança, estabilidade, motivação e qualidade de vida. Os principais autores utilizados para a discussão foram Chiavenato (2010), Marras (2009), Limongi-França (2011), Robbins (2005) e Bittencourt (2010). Ametodologia utilizada foi de natureza descritiva, com abordagem qualitativa. Foram sujeitos de pesquisa sete gerentes de agências bancárias de Porto Alegre - RS. A técnica de pesquisa e coleta de dados foi a entrevista com roteiro semiestruturado e um roteiro de observação nas agências visitadas, focando no próprio respondente e no ambiente aoseu redor. A técnica de análise de dados foi a análise interpretativa das respostas, com comparações dos dados pesquisados com o referencial teórico exposto no trabalho. A conclusão deste estudo foi de que todos os candidatos usam do gerenciamento de impressão, consciente ou  inconscientemente, para se prepararem para as entrevistas. Cada candidato tentou mostrar suas melhores qualidades, de acordo com a sua percepção e suas experiências passadas, tanto pessoalmente, quanto culturais e sociais. A autopromoção foi a estratégia com maior representatividade; e a concordância e o comportamento não verbal como as táticas mais utilizadas, na visão dos entrevistados sobre os candidatos a vagas em agências bancárias.

O mercado de trabalho atual conta com um novo modelo de profissional disponível: os nômades globais. São indivíduos que saem do seu país de origem para conhecer e absorver conhecimentos e costumes nas mais variadas culturas e retornam ao seu país com essa bagagem de conhecimento. Desta forma, as organizações precisam estar preparadaspara receber e absorver o máximo de conhecimento possíveldeste profissional. Este estudo tem como objetivo identificar como as experiências no exterior agregam na carreira do profissional de administração. A metodologia utilizada é de natureza exploratória, com abordagem qualitativa. Foram sujeitos da pesquisa nove acadêmicos e bacharéis em administração que, em algum momento de sua vida,passaram por experiências fora do seu país de origem, estes localizados no estado do Rio Grande do Sul. A técnica de coleta de dados foi entrevista com roteiro semiestruturado. A técnica de análise dos dados foi interpretativa, com comparações com o referencial teórico. A conclusão deste estudo é que para ser considerado um nômade global o indivíduo deve se sentir desta forma e buscar desenvolver suas aptidões através das experiências adquiridas em outros países que nãoo seu de origem. Há espaço para que os profissionais desenvolvam suas tarefas com base em suas experiências em outros países, porém as empresas ainda precisam se abrir para incentivar o profissional a aplicar seus conhecimentos adquiridos fora, no cotidiano das atividades da organização.

No Brasil, a população feminina é maioria, e há séculos vem lutando pela equiparação de direitos, incluindo-se ai os do mundo do trabalho. A igualdade é fundamental para o desenvolvimento e progresso das organizações e da sociedade como um todo. A partir deste quadro, este artigo se propôs a verificar os desafios enfrentados por um grupo de mulheres, das diferentes regiões demográficas do Brasil e três gestoras,no mercado de trabalho, através de uma pesquisa quantitativa e qualitativa. Se estabeleceu identificar o perfil das pesquisadas; verificar a percepção destas mulheres sobre questões como a discriminação de gênero, assédio, padrões de beleza e diferença salarial no ambiente de trabalho; e averiguar junto às pesquisadas se a maternidade influenciana disputa por vagas ou cargos no ambiente de trabalho.Por meio da análise destas informações coletadas junto das entrevistadas foi possível concluir que o universo de mulheres da pesquisa sentem que há uma grande diferença entre o tratamento dispensado aos dois gêneros no mundo do trabalho e que os diversos direitos assegurados por lei,não impedem a discriminação de gênero.

Background

As patients age, caregivers increasingly provide essential support and patient information. We sought to determine if patient-caregiver assessments of patient health differ and if differences contribute to burden in caregivers of older adults with cancer.

Materials and Methods

One hundred patients, aged ≥65, and their caregivers independently assessed patient function, comorbidity, nutrition, social activity, social support, and mental health. Caregivers completed the Caregiver Strain Index (CSI). Patient-caregiver assessments were compared using the Wilcoxon signed rank test and paired t test. Association between caregiver burden and differences between patient-caregiver assessments was examined using generalized linear regression.

Results

Median patient age was 70 (range 65–91) and 70% had advanced disease. Sixty percent of patients reported requiring help with instrumental activities of daily living (IADLs); most had good social support (median Medical Outcomes Study [MOS]-Social Support Survey score 92) and mental health (median Mental Health Inventory score 85).

Caregivers were a median age of 66 (range 28–85), 73% female, 68% spousal caregivers, and 79% lived with the patient. Caregivers rated patients as having poorer physical function (more IADLs dependency [p = .008], lower Karnofsky Performance Status [p = .02], lower MOS-Physical Function [p < .0001]), poorer mental health (p = .0002), and having more social support (p = .03) than patients themselves. Three-quarters of caregivers experienced some caregiver burden (mean CSI score 3.1). Only differences in patient-caregiver assessment of the patient's need for help with IADLs were associated with increased caregiver burden (p = .03).

Conclusion

Patient-caregiver assessments of patient function, mental health, and social support differ. However, only differences in assessment of IADLs dependency were associated with increased caregiver burden.
