Cognitive effects of long-term androgen deprivation therapy in older men with prostate cancer.

OBJECTIVE: Androgen deprivation therapy (ADT) is a common treatment for prostate cancer (PCa), with increasing numbers of men on ADT for longer. Limited evidence suggests ADT impacts cognition. This study addressed gaps in the literature by focusing on older men with PCa and assessing ADT usage longer than 1 year. METHODS: This study of 133 men ≥65 years of age with PCa included two groups: (1) men on ADT for 1-3 years (ADT-exposed), and (2) a comparison group of men with PCa not on ADT (ADT-unexposed). Group comparisons on individual neuropsychological test scores are reported, as well as effect sizes (Cohen's d). RESULTS: Half (n = 67) of the sample was ADT-exposed and half (n = 66) were unexposed. The average age was 72 years, most were White, and over 50% had at least secondary education. There were no statistically significant differences between groups by age, race, or education. Unadjusted analyses showed the ADT-exposed group, compared with the ADT-unexposed group, performed significantly lower in domains of verbal learning (d = 0.45-0.52, p = 0.01 to <0.01), verbal recall (d = 0.33-0.54, p = 0.06 to <0.01), and possible effects in visuospatial construction (d = 0.33, p = 0.08 to 0.06). When controlling for age and education, similar patterns emerged. The ADT exposed-group performed significantly lower in domains of verbal learning (d = 0.45-0.52, p = 0.06 to 0.03) and verbal recall (d = 0.33-0.54, p = 0.11 to 0.03), and possible effects in visuospatial construction d = 0.33, p = 0.18 to 0.13. CONCLUSIONS: This study suggests long-term ADT exposure impacts verbal learning, verbal recall, and possibly visuospatial abilities in older men (≥65) with PCa. The potential cognitive effects of ADT should be discussed with older patients considering long-term use of ADT.

Definition and validation of the nursing diagnosis label "wish to die": a research protocol.

BACKGROUND: Euthanasia has been incorporated into the health services of seven countries. The legalisation of these practices has important repercussions for the competences of nurses, and it raises questions about their role. When a patient with advanced disease expresses a wish to die, what is expected of nurses? What are the needs of these patients, and what kind of care plan do they require? What level of autonomy might nurses have when caring for these patients? The degree of autonomy that nurses might or should have when it comes to addressing such a wish and caring for these patients has yet to be defined. Recognising the wish to die as a nursing diagnosis would be an important step towards ensuring that these patients receive adequate nursing care. This study-protocol aims to define and validate the nursing diagnosis wish to die in patients with advanced disease, establishing its defining characteristics and related factors; to define nursing-specific interventions for this new diagnosis. METHODS: A prospective three-phase study will be carried out. Phase-A) Foundational knowledge: an umbrella review of systematic reviews will be conducted; Phase-B) Definition and validation of the diagnostic nomenclature, defining characteristics and related factors by means of an expert panel, a Delphi study and application of Fehring's diagnostic content validation model; Phase-C) Definition of nursing-specific interventions for the new diagnosis. At least 200 academic and clinical nurses with expertise in the field of palliative care or primary health care will be recruited as participants across the three phases. DISCUSSION: The definition of the wish to die as a nursing diagnosis would promote greater recognition and autonomy for nurses in the care of patients who express such a wish, providing an opportunity to alleviate underlying suffering through nursing-specific interventions and drawing attention to the needs of patients with advanced disease. The new diagnosis would be an addition to nursing science and would provide a framework for providing care to people with advanced disease who express such a wish. Nurses would gain professional autonomy about identifying, exploring and responding clinically to such a wish.

Development of a Guide to Multidimensional Needs Assessment in the Palliative Care Initial Encounter (MAP).

CONTEXT: Ensuring patient-centered palliative care requires a comprehensive assessment of needs beginning in the initial encounter. However, there is no generally accepted guide for carrying out this multidimensional needs assessment as a first step in palliative intervention. OBJECTIVES: To develop an expert panel-endorsed interview guide that would enable proactive and systematic Multidimensional needs Assessment in the Palliative care initial encounter (MAP). METHODS: A preliminary version of the MAP guide was drafted based on a published literature review, published semistructured interviews with 20 patients, 20 family carers, and 20 palliative care professionals, and a nominal group process with palliative care professionals and a representative of the national patient's association. Consensus regarding its content was obtained through a modified Delphi process involving a panel of palliative care physicians from across Spain. RESULTS: The published systematic literature review and qualitative study resulted in the identification of 55 needs, which were sorted and grouped by the nominal group. Following the Delphi process, the list of needs was reduced to 47, linked to six domains: Clinical history and medical conditions (n = 8), Physical symptoms (n = 17), Functional and cognitive status (n = 4), Psycho-emotional symptoms (n = 5), Social issues (n = 8), and Spiritual and existential concerns (n = 5). CONCLUSION: MAP is an expert panel-endorsed semi-structured clinical interview guide for the comprehensive, systematic, and proactive initial assessment to efficiently assess multiple domains while adjusting to the needs of each patient. A future study will assess the feasibility of using the MAP guide within the timeframe of the palliative care initial encounter.

What makes the palliative care initial encounter meaningful? A descriptive study with patients with cancer, family carers and palliative care professionals.

BACKGROUND: The palliative care initial encounter can have a positive impact on the quality of life of patients and family carers if it proves to be a meaningful experience. A better understanding of what makes the encounter meaningful would reinforce the provision of person-centred, quality palliative care. AIM: To explore the expectations that patients with cancer, family carers and palliative care professionals have of this initial encounter. DESIGN: Qualitative descriptive study with content analysis of transcripts from 60 semi-structured interviews. SETTING/PARTICIPANTS: Twenty patients with cancer, 20 family carers and 20 palliative care professionals from 10 institutions across Spain. RESULTS: Four themes were developed from the analysis of interviews: (1) the initial encounter as an opportunity to understand what palliative care entails; (2) individualised care; (3) professional commitment to the patient and family carers: present and future; and (4) acknowledgement. CONCLUSION: The initial encounter becomes meaningful when it facilitates a shared understanding of what palliative care entails and acknowledgement of the needs and/or roles of patients with cancer, family carers and professionals. Further studies are required to explore how a perception of acknowledgement may best be fostered in the initial encounter.

Experiences of Isolation among Patients Hospitalized during an Infectious Disease Outbreak: A Systematic Review and Meta-Ethnography.

Hospital isolation is common for people during infectious disease outbreaks. Anxiety, stress, depression and other psychosocial outcomes have been reported due to these measures. However, there is scarce evidence about the experience of being isolated and about best practices for empathic clinical care in these circumstances. The aim of this study was to explore the experience of isolation on patients hospitalized during an infectious disease outbreak. A systematic review and meta-ethnography was carried out. A search strategy was applied to the PubMed, CINAHL, Web of Science, and PsycINFO databases on April 14, 2021 and again May 2, 2022. Data synthesis was conducted using Noblit and Hare's method of qualitative thematic synthesis. Twenty reports were included in this review: 16 qualitative, two mixed-methods (only the qualitative part was analyzed), plus 2 personal view pieces. They described the experiences of a total of 337 people hospitalized and isolated with an infectious disease. Following analysis and coding of data, four themes emerged: 1) Feelings triggered by isolation; 2) Coping strategies; 3) Connection/disconnection; 4) Factors that influence the experience of isolation. Despite a sensitive search strategy, limited studies represent patient experiences using qualitative methods. The experience of isolation among patients hospitalized during an outbreak is characterized by fear, perceived stigma, and a sense of disconnection from others and the outside world due to a lack of information. Fostering a person-centered care model could help hospitalized patients develop adaptive mechanisms that minimize the impact of isolation.

A Smart System for Remote Monitoring of Patients in Palliative Care (HumanITcare Platform): Mixed Methods Study.

BACKGROUND: Due to the complexities of advanced illnesses and their treatments, it can be difficult for patients in palliative care to maintain their quality of life. Telemedicine interventions in chronic disease management engage patients in their care, provide continuous follow-up by their health care providers, identify symptoms earlier, and allow a quick response to illness-related decline. OBJECTIVE: We aimed to detail and reflect on the design of an app and evaluate its feasibility to monitor the clinical situation of patients with advanced illnesses. METHODS: This study used a mixed methods design using qualitative methods to inform app development and design and quantitative methods for data collection and analysis of patient evaluations. Palliative care units in 2 Spanish university hospitals (Nuestra Señora de la Candelaria in Santa Cruz de Tenerife and University Hospital Complex of Ferrol in A Coruña) carried out a literature review, designed the study protocol, and obtained approval from the Ethics Committee from June to December 2020. In addition, focus group meetings were held, and the design and technical development of the app were elaborated on and subsequently presented in the participating palliative care units. From January to March 2021, the app was made public on the App Store and Play Store, and a pilot study with patients was carried out in April to September 2021. RESULTS: Six focus group meetings were held that included doctors, nurses, app developers, technology consultants, and sponsors. In addition, the technology consultants presented their results 3 times in the participating palliative care units to obtain feedback. After the app's final design, it was possible to publish it on the usual servers and begin its evaluation in patients (n=60, median age 72 years). Sixty percent (n=36) of the participants were women and 40% (n=24) were men. The most prevalent advanced pathology was cancer (n=46, 76%), followed by other diseases (n=7, 12%) and amyotrophic lateral sclerosis (n=5, 8%). Seventy percent (n=42) of the patients were already in follow-up prior to the start of the study, while 30% (n=18) were included at the start of their follow-up. The information in the app was collected and entered by relatives or caregivers in 60% (n=36) of the cases. The median follow-up was 52 (IQR 14-104) days. In all, 69% (n=41) had a follow-up >30 days (10 were deceased and 9 were missing data). The use of the different sections of the app ranged from 37% (n=22) for the glycemic record to 90% (n=54) for the constipation scale). Patients and caregivers were delighted with its ease of use and usefulness. CONCLUSIONS: Incorporating an intelligent remote patient monitoring system in clinical practice for patients in palliative care can improve access to health services and provide more information to professionals.

The past and future of uncertainty in advanced illness: a systematic scoping review of underlying cognitive processes.

BACKGROUND: To explain what cognitive capacity shapes uncertainty in advanced illness by identifying the types of evidence, mapping underlying cognitive processes to uncertainty, and outlining future directions for research and interventions. DESIGN: A systematic scoping review of mixed study designs was carried out following the methodological framework of Arksey and O'Malley (2005) and using qualitative content analysis. METHODS: PubMed, CINAHL, Embase, and PsycINFO were searched for original studies published in full and in English through December 2021 that reported on uncertainty in illness and related cognitions, cognitive science, or cognitive functions. RESULTS: After screening 978, 18 articles met the inclusion criteria for review. We found the cognitive capacity of mental time travel - to relive the past or foresee life in the future - interacted with episodic memory retrieval to inform decision-making, and prospection to imagine, predict or prepare for future outcomes to determine lesser or greater uncertainty in advanced illness. CONCLUSIONS: Mental time travel is a fundamental cognitive function when the future is limited by an advanced illness, to review life as a meaningful narrative. The role of mental time travel to construct or make sense of uncertain futures inherent in advanced illness can inform theory and targets for intervention.

Control in patients with advanced cancer: an interpretative phenomenological study.

BACKGROUND: In the context of life-threatening illness, loss of control is argued as a source of suffering and loss of perceived dignity, whereas having control over the dying process has been seen as a way of maintaining personal independence. Little is known about the meaning of control from the patients' perspectives. Thus, the aim of this study was to explore how patients with advanced cancer understand control, in terms of underlying beliefs, attitudes, and expectations consistent with self-efficacy, in different dimensions of their life, their illness, and their healthcare. METHODS: We conducted semi-structured qualitative interviews using an interpretive phenomenological analysis approach. Patients with advanced cancer from an oncology unit and a palliative care unit from Barcelona (Spain) were recruited. The inclusion criteria were a) ≥ 18 years old; b) fluency in Spanish or Catalan; c) outpatients diagnosed with advanced cancer; d) Eastern Cooperative Oncology Group (ECOG) between 0 and 3; e) judged by their physician or nurse to be emotionally stable; f) considered to have control over their illness and circumstances according to their responsible physician; and g) signed informed consent. RESULTS: We interviewed eight participants (ages ranged from 29 to 70 years, six were female). Two themes were identified: 1) factors that influence the perception of control, with subthemes: uncertainty about future suffering, character traits underlying a need for control; sense of lack of care as a source of loss of control; and 2) perceiving control over an uncontrollable illness, explained by perceived control over subjective wellbeing and adjusting the focus of control. The data allowed us to identify strategies that promote a sense of control in these patients. CONCLUSIONS: The illness, according to the participants, was experienced as series of losses. However, attention was often focused on areas where they continued to have control. These findings selectively reflect experiences of those who see themselves able to effect outcomes in life, suggesting future research should address how both family members and healthcare professionals can help to empower all patients.

Thinking clearly about dignity: relationships between cognitive processes underlying perceived dignity as determinants of psychological adjustment.

BACKGROUND: Public and professional views strongly equate dignity among the dying with their abilities to make decisions about medical and personal treatment and care. To make these decisions requires cognitive processes that inform our understanding of circumstances by integrating thoughts, experiences, and perceptions with prior knowledge. But patients with terminal illnesses, especially cancer, often experience problems stemming from cognitive changes and the cognitive state of uncertainty that can interfere with knowing what options for care are essential to targeting their sense of dignity. This paper aims to propose and test a model that defines targets for dignity-conserving care from underlying cognitive changes as antecedents to uncertainty that impact psychological adjustment of patients with advanced cancer. PARTICIPANTS AND PROCEDURE: This is a cross-sectional observational study using participant data from 257 patients with advanced cancer. The Patient Dignity Inventory and the Hospital Anxiety and Depression Scale were administered to patients and analyzed according to model hypotheses. RESULTS: Analyses used structural equational modeling to confirm model pathways. In the context of perceived dignity in advanced cancer, there was a direct pathway from patient reported problems with cognitive changes to uncertainty, that in turn had both direct and indirect effects on depression. CONCLUSIONS: The results suggest that cognitive changes challenge perceptions of dignity and can independently be targeted as modifiable processes to provide dignity-conserving care.

What defines the comprehensive assessment of needs in palliative care? An integrative systematic review.

BACKGROUND: The comprehensive assessment of needs in palliative care identifies where patients most want attention to guide clinical decisions that tailor care provision from their first encounters. AIM: To define how and what needs are identified by the comprehensive assessment of needs in the original peer-reviewed articles in the field of palliative care. DESIGN: An integrative systematic review as outlined by Whittemore and Knafl. Quality appraisal performed using the Mixed Methods Appraisal Tool. DATA SOURCES: PubMed, CINAHL, PsycINFO, Web of Science databases searched through May 2019 and updated in July 2020. RESULTS: Forty-nine articles met inclusion criteria for original articles in English or Spanish reporting comprehensive assessment of needs of adult patients receiving palliative care. The majority (41/49) of studies were moderate to high quality. Two themes were identified: (1) How a comprehensive assessment of needs should be carried out in palliative care, which reflected a preference to develop structured tools for assessment; (2) What needs of patients should be assessed in the comprehensive assessment of needs in palliative care, which conveyed a trend to assess beyond core domains - physical, psychological, social, spiritual - with information and practical most prevalent, but with substantial variation in specifying and classifying needs into domains. CONCLUSIONS: The assessment of needs in palliative care is comprehensive but lacks consensus on the needs and domains that should be assessed by the palliative care team. Future studies should better define what needs can be standardized into the assessment to improve process of care and patient satisfaction.

Screening for the Desire to Die in the First Palliative Care Encounter: A Proof-of-Concept Study.

Context: There is a lack of consensus about the appropriate moment to assess a potential wish to hasten death (WTHD) in patients with life-threatening illness, despite evidence of its positive appraisal among patients. Objectives: To evaluate the practical potential and acceptability of questions about the WTHD in the first palliative care (PC) clinical encounter. Design: A proof-of-concept single-arm unmasked trial. Subjects: We enrolled 30 advanced cancer patients, 16 inpatients and 14 outpatients in their first PC clinical encounter. Measurements: We assessed the WTHD using a semistructured interview guide, the Assessment of the Frequency and Extent of the Desire to Die (AFEDD) embedded in a multidimensional needs assessment carried out during the first PC encounter. Information about practical potential [patients consider the assessment (a) important and (b) helpful] and acceptability [patients (a) understand and (b) are not bothered by the questions] was obtained. Results: Thirty-two patients were approached and 30 (94%) agreed to participate. The WTHD was present in two outpatients and eight inpatients. The question to assess WTHD were well understood by 94% of patients and was considered not bothersome by 87% and quite or very helpful by 80%, regardless of whether they had WTHD. Conclusions: The results support that clinicians can integrate screening for the WTHD in usual clinical practice within a multidimensional needs assessment. Patient acceptability suggests that this as a part of patient-centered care including in the first PC clinical encounter. Further studies are needed to confirm efficacy and safety in larger and different populations.

Older Age: A Protective Factor Against Perceived Dignity-Related Distress in Patients With Advanced Cancer?

CONTEXT: Most older adults will face threats to loss of health and social support, which can affect their perceived dignity. Although problems with perceived dignity increase in the context of cancer, the specific experience for those older compared with younger patients with advanced cancer has not been described despite its contributions to the wish to hasten death (WTHD). OBJECTIVES: To understand the influence of age group to the perception of dignity, considering changes in quality of life and the WTHD in patients with advanced cancer. METHODS: The Patient Dignity Inventory was administered to 194 patients with advanced cancer. The data were analyzed by separating the sample into age groups younger than 65 years (N = 106) or 65 years and older (N = 88). Linear regression models were adjusted with the explanatory variables of WTHD, quality of life, as well as functional status, physical dependence, depression, anxiety, and sociodemographic variables. RESULTS: Older patients showed a 2.6% decrease in the total scores of perceived dignity-related distress compared to younger patients. CONCLUSION: Older age could be a protective factor against the perception of loss of dignity in patients with advanced cancer, a more positive perspective of the aging experience.

Prospective evaluation of functional brain activity and oxidative damage in breast cancer: changes in task-induced deactivation during a working memory task.

Cancer-related cognitive dysfunction is an important issue for breast cancer survivors. Previous research has identified both cross-sectional and longitudinal alterations in brain function related to cancer status and treatment. In this study, we prospectively collected functional magnetic resonance imaging data in breast cancer cases treated with adjuvant chemotherapy and in controls with no cancer history during a working memory task. Data and blood specimens were collected immediately prior to the start of treatment (baseline) and following completion of treatment (follow-up), and at yoked intervals for controls. In secondary analysis we assessed the levels of oxidative DNA damage in peripheral blood lymphocytes of cases and controls using the Comet assay. A significant group*time interaction revealed reduced deactivation in the superior frontal gyrus in the controls at follow-up, in contrast to cases, who exhibited similar magnitude of deactivation at baseline and follow-up. Working memory performance indicated a significant improvement in the controls at follow-up, and no change in performance in cases. In secondary analyses, oxidative DNA damage levels were elevated in the cases at follow-up compared to controls, but no associations were found between the Comet assay variables and functional imaging at either time-point or group. In light of previous reports on task induced deactivations, our findings reflect continuing effortful processing at follow-up in the breast cancer group, with relatively less effortful processing in the control group given the reduced novelty and practice effects from the baseline to follow-up.

Recognition of cognitive complaints for patients with advanced cancer.

Fueled by increasing recognition that cancer-related cognitive impairment impacts quality of life among cancer survivors, we suggest that researchers and clinicians expand their focus to acknowledge the impact of cognitive changes for those with advanced cancer. We outline five reasons that patients with advanced cancer would benefit from comprehensive assessments that include questions about cognitive complaints. Advanced cancer has all the characteristics that would lead to cognitive changes. Patients with advanced cancer may have a higher risk for cognitive impairment due to aggressive chemotherapies, higher symptom burden, and greater psychosocial distress. This commentary contextualizes how cognitive complaints may relate to multiple factors relevant to the advanced cancer patient. By simply asking the patient about their perceived cognitive changes, we argue this may be a stepping stone to finding non-pharmacological ways to address cognitive impairment.

Impact of transcranial direct current stimulation on sustained attention in breast cancer survivors: Evidence for feasibility, tolerability, and initial efficacy.

BACKGROUND: A significant subset of breast cancer survivors experience cognitive difficulties in attention and memory, which persist for years following treatment. Transcranial direct current stimulation (tDCS) has been shown to be effective in improving working memory, attention, processing speed, and other cognitive functions in both healthy and clinical populations. To date, no studies have examined tDCS for rehabilitation of cancer-related cognitive dysfunction. OBJECTIVE/HYPOTHESIS: We aimed to provide preliminary evidence for feasibility, tolerability, acceptability, and efficacy of tDCS in improving performance on a measure of sustained attention. METHODS: In a within-subjects design, 16 breast cancer survivors underwent 2 consecutive days of active tDCS over the prefrontal cortex, and 2 days of sham tDCS, counterbalanced for order of stimulation condition, while performing a continuous performance test. RESULTS: Stimulation was feasible and tolerable, with 89% of participants completing all sessions, and none reporting more than mild to moderate discomfort. Analyses of efficacy showed that during active stimulation, participants had significantly lower standard errors of reaction times overall, indicating better sustained attention ability, as compared to sham stimulation (p < 0.05). Furthermore, the effect of stimulation on standard errors of reaction times differed by inter-stimulus interval (ISI): for 1 and 2 s ISIs, there was no significant difference in performance between sham and active tDCS conditions, but for 4 s ISIs, stimulation improved variability in response times relative to sham (p < 0.05). CONCLUSIONS: Results suggest that tDCS is feasible, tolerable, and may be an effective intervention to improve sustained attention difficulties in survivors with cancer-related cognitive dysfunction.

Proactive and systematic multidimensional needs assessment in patients with advanced cancer approaching palliative care: a study protocol.

INTRODUCTION: The benefits of palliative care rely on how healthcare professionals assess patients' needs in the initial encounter/s; crucial to the design of a personalised therapeutic plan. However, there is currently no evidence-based guideline to perform this needs assessment. We aim to design and evaluate a proactive and systematic method for the needs assessment using quality guidelines for developing complex interventions. This will involve patients, their relatives and healthcare professionals in all phases of the study and its communication to offer clinical practice a reliable approach to address the palliative needs of patients. METHODS AND ANALYSIS: To design and assess the feasibility of an evidence-based, proactive and systematic Multidimensional needs Assessment in Palliative care (MAP) as a semistructured clinical interview guide for initial palliative care encounter/s in patients with advanced cancer. This is a two-phase multisite project conducted over 36 months between May 2019 and May 2022. Phase I includes a systematic review, discussions with stakeholders and Delphi consensus. The evidence gathered from phase I will be the basis for the initial versions of the MAP, then submitted to Delphi consensus to develop a preliminary guide of the MAP for the training of clinicians in the feasibility phase. Phase II is a mixed-methods multicenter feasibility study that will assess the MAP's acceptability, participation, practicality, adaptation and implementation. A nested qualitative study will purposively sample a subset of participants to add preliminary clues about the benefits and barriers of the MAP. The evidence gathered from phase II will build a MAP user guide and educational programme for use in clinical practice. ETHICS AND DISSEMINATION: Ethical approval for this study has been granted by the university research ethics committee where the study will be carried out (approval reference MED-2018-10). Dissemination will be informed by the results obtained and communication will occur throughout.

Episodic memory for visual scenes suggests compensatory brain activity in breast cancer patients: a prospective longitudinal fMRI study.

It has been hypothesized that breast cancer and its chemotherapy can impart functional neural changes via an overlap with biological mechanisms associated with aging. Here we used fMRI to assess whether changes in neural activity accompanying visual episodic memory encoding and retrieval suggest altered activations according to patterns seen in functional imaging of cognitive aging. In a prospective longitudinal design, breast cancer patients (n = 13) were scanned during memory encoding and retrieval before and after chemotherapy treatment, and compared to healthy-age matched controls (n = 13). Our results indicate that despite equivalent behavioral performance, encoding and retrieval resulted in increased activation of prefrontal regions for the breast cancer group compared to controls for both before and after chemotherapy treatment. This was accompanied by decreased activity in posterior brain regions after chemotherapy, particularly those involved in visual processing, for the breast cancer group compared to controls. These findings are discussed as evidence for a possible anterior shift in neural processing to compensate for deficiencies in posterior brain regions, consistent with an accelerated aging account. Cancer and chemotherapy can impact brain regions underlying episodic memory, leading to additional recruitment of control regions, which may be linked to mechanisms related to aging.

Patient-Reported Physical Function Measures in Cancer Clinical Trials.

Patient-reported outcomes (PROs) are increasingly used to monitor treatment-related symptoms and physical function decrements in cancer clinical trials. As more patients enter survivorship, it is important to capture PRO physical function throughout trials to help restore pretreatment levels of function. We completed a systematic review of PRO physical function measures used in cancer clinical trials and evaluated their psychometric properties on the basis of guidelines from the US Food and Drug Administration. Five databases were searched through October 2015: PubMed/MEDLINE, EMBASE, CINAHL (Cumulative Index of Nursing and Allied Health Literature), Health and Psychosocial Instruments, and Cochrane. From an initial total of 10,233 articles, we identified 108 trials that captured PRO physical function. Within these trials, approximately 67% used the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and 25% used the Medical Outcomes Study Short Form 36. Both the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and Medical Outcomes Study Short Form 36 instruments generically satisfy most Food and Drug Administration requirements, although neither sought direct patient input as part of item development. The newer Patient-Reported Outcomes Measurement Information System physical function short form may be a brief, viable alternative. Clinicians should carefully consider the psychometric properties of these measures when incorporating PRO instrumentation into clinical trial design to provide a more comprehensive understanding of patient function.

Cancer-related cognitive impairment in older adults.

PURPOSE OF REVIEW: Cancer, aging, and cognition form a complicated interface that can challenge patients, caretakers, and healthcare professionals. Although the typical aging process allows for compensatory mechanisms to help maintain daily functioning, cancer and cancer treatments can remove the fail-safes and exacerbate cognitive decline. As a result, older cancer patients can experience increased morbidity and mortality. The goal of this article is to provide additional assessment strategies, diagnostic considerations, and treatment options for providers taking care of this growing population. RECENT FINDINGS: In this review, we will discuss current areas of research with regard to epidemiology and our current understanding of cancer-related cognitive impairment in the older patient, while reinforcing the importance of the Comprehensive Geriatric Assessment in assessment, prognosis, and treatment guidance. SUMMARY: Although cognitive impairment in the older cancer patient may be an increasing cause of concern with several gaps in research, there are opportunities to take a methodical treatment approach.

Increased contextual cue utilization with tDCS over the prefrontal cortex during a recognition task.

The precise role of the prefrontal and posterior parietal cortices in recognition performance remains controversial, with questions about whether these regions contribute to recognition via the availability of mnemonic evidence or via decision biases and retrieval orientation. Here we used an explicit memory cueing paradigm, whereby external cues probabilistically predict upcoming memoranda as old or new, in our case with 75% validity, and these cues affect recognition decision biases in the direction of the cue. The present study applied bilateral transcranial direct current stimulation (tDCS) over prefrontal or posterior parietal cortex, or sham tDCS, to test the causal role of these regions in recognition accuracy or decision biasing. Participants who received tDCS over prefrontal cortex showed increased cue utilization compared to tDCS over posterior parietal cortex and sham tDCS, suggesting that the prefrontal cortex is involved in processes that contribute to decision biases in memory.
