Risk of significant functional impairment across cancer diagnosis and care continuum.

BACKGROUND: The authors examined baseline physical functional (PF) impairment among cancer outpatients in the National Cancer Institute Cancer Moonshot study Northwestern University Improving the Management of Symptoms During and Following Cancer Treatment (NU IMPACT). They hypothesized that PF impairment, measured with the Patient Reported Outcome Measurement Information System-Physical Function (PROMIS-PF) survey, would (1) be common and more prevalent for patients receiving treatment compared with no treatment and (2) differ across tumor types, independent of cancer continuum phase. METHODS: Adults who were diagnosed with cancer in NU IMPACT (n = 2273) were sampled, and their PROMIS-PF scores were compared across tumor types and cancer continuum (curative, noncurative, or no treatment), with scores ≤40 indicating moderate-severe impairment. Multivariable logistic regression models were used to evaluate the relation among patient and cancer factors and PF scores using a 95% confidence interval. RESULTS: Forty percent of the surveyed patients reported moderate-severe PF impairment. Patients with melanoma reported the least impairment, and those with lung cancer were 6.5 times more likely to have moderate-severe impairment (95% confidence interval, 2.393-17.769). The noncurative group was 1.5 times more likely to have moderate-severe impairment (95% confidence interval, 1.045-2.145; mean score, 43; p < .001) than the curative (mean score, 6) and no treatment (mean score, 48) groups. One-third of those who reported PF impairment also had significant pain and/or fatigue. CONCLUSIONS: A sizeable minority experienced PF impairment across tumor types for which pain and/or fatigue co-occurred, particularly in the noncurative group. The PROMIS-PF survey effectively identified variations in physical function. Future studies will explore how screening for PF impairment can be used to refer patients for appropriate cancer rehabilitation services.

Cardiopulmonary and metabolic responses during a 2-day CPET in myalgic encephalomyelitis/chronic fatigue syndrome: translating reduced oxygen consumption to impairment status to treatment considerations.

BACKGROUND: Post-exertional malaise (PEM), the hallmark symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), represents a constellation of abnormal responses to physical, cognitive, and/or emotional exertion including profound fatigue, cognitive dysfunction, and exertion intolerance, among numerous other maladies. Two sequential cardiopulmonary exercise tests (2-d CPET) provide objective evidence of abnormal responses to exertion in ME/CFS but validated only in studies with small sample sizes. Further, translation of results to impairment status and approaches to symptom reduction are lacking. METHODS: Participants with ME/CFS (Canadian Criteria; n = 84) and sedentary controls (CTL; n = 71) completed two CPETs on a cycle ergometer separated by 24 h. Two-way repeated measures ANOVA compared CPET measures at rest, ventilatory/anaerobic threshold (VAT), and peak effort between phenotypes and CPETs. Intraclass correlations described stability of CPET measures across tests, and relevant objective CPET data indicated impairment status. A subset of case-control pairs (n = 55) matched for aerobic capacity, age, and sex, were also analyzed. RESULTS: Unlike CTL, ME/CFS failed to reproduce CPET-1 measures during CPET-2 with significant declines at peak exertion in work, exercise time, V ˙ e, V ˙ O2, V ˙ CO2, V ˙ T, HR, O2pulse, DBP, and RPP. Likewise, CPET-2 declines were observed at VAT for V ˙ e/ V ˙ CO2, PetCO2, O2pulse, work, V ˙ O2 and SBP. Perception of effort (RPE) exceeded maximum effort criteria for ME/CFS and CTL on both CPETs. Results were similar in matched pairs. Intraclass correlations revealed greater stability in CPET variables across test days in CTL compared to ME/CFS owing to CPET-2 declines in ME/CFS. Lastly, CPET-2 data signaled more severe impairment status for ME/CFS compared to CPET-1. CONCLUSIONS: Presently, this is the largest 2-d CPET study of ME/CFS to substantiate impaired recovery in ME/CFS following an exertional stressor. Abnormal post-exertional CPET responses persisted compared to CTL matched for aerobic capacity, indicating that fitness level does not predispose to exertion intolerance in ME/CFS. Moreover, contributions to exertion intolerance in ME/CFS by disrupted cardiac, pulmonary, and metabolic factors implicates autonomic nervous system dysregulation of blood flow and oxygen delivery for energy metabolism. The observable declines in post-exertional energy metabolism translate notably to a worsening of impairment status. Treatment considerations to address tangible reductions in physiological function are proffered.

Caring for Patients with Functional Impairment in Middle Age: Perspectives from Primary Care Providers and Geriatricians.

BACKGROUND: The prevalence of functional impairment is increasing among middle-aged adults and is associated with adverse health outcomes. Primary care providers (PCPs) and geriatricians may have important insights about optimal approaches to caring for these patients, but little is known about their perspectives. OBJECTIVE: To examine PCPs' and geriatricians' perspectives on clinical needs and optimal approaches to care for middle-aged patients with functional impairment. DESIGN: Qualitative study using semi-structured interviews. PARTICIPANTS: PCPs and geriatricians from outpatient practices in the San Francisco Bay area. APPROACH: Interviews focused on characteristics and care needs of middle-aged patients with functional impairment and models of care to address these needs. We analyzed interviews using hybrid deductive-inductive qualitative thematic analysis. KEY RESULTS: Clinicians (14 PCPs, 15 geriatricians) described distinct characteristics of functional impairment in middle-aged versus older adults, such as different rates of onset, but similar clinical needs. Despite these similar needs, clinicians identified age-specific barriers to delivering optimal care to middle-aged patients. These included system-level challenges such as limited access to insurance and social services; practice- and clinician-level barriers including inadequate clinician training; and patient-level factors including less access to family caregivers and perceptions of stigma. To overcome these challenges, clinicians suggested clinical approaches including addressing health-related social needs within healthcare systems; implementing practice-based models that are multi-disciplinary, team-based, and coordinated; training clinicians to effectively manage functional impairment; and expanding community-based services and supports to help patients navigate the medical system. Identified needs, challenges, and solutions were generally similar across geriatricians and PCPs. CONCLUSIONS: Clinicians face challenges in delivering optimal care to middle-aged patients who have functional impairments similar to their older counterparts but lack access to services and supports available to older people. These findings suggest the importance of increasing access to care models that address functional impairment regardless of age.

Neighborhood Socioeconomic Deprivation and Health Care Costs in Older Community-Dwelling Adults: Importance of Functional Impairment and Frailty.

BACKGROUND: Low neighborhood socioeconomic status is associated with adverse health outcomes, but its association with health care costs in older adults is uncertain. OBJECTIVES: To estimate the association of neighborhood Area Deprivation Index (ADI) with total, inpatient, outpatient, skilled nursing facility (SNF), and home health care (HHC) costs among older community-dwelling Medicare beneficiaries, and determine whether these associations are explained by multimorbidity, phenotypic frailty, or functional impairments. DESIGN: Four prospective cohort studies linked with each other and with Medicare claims. PARTICIPANTS: In total, 8165 community-dwelling fee-for-service beneficiaries (mean age 79.2 years, 52.9% female). MAIN MEASURES: ADI of participant residence census tract, Hierarchical Conditions Category multimorbidity score, self-reported functional impairments (difficulty performing four activities of daily living), and frailty phenotype. Total, inpatient, outpatient, post-acute SNF, and HHC costs (US 2020 dollars) for 36 months after the index examination. KEY RESULTS: Mean incremental annualized total health care costs adjusted for age, race/ethnicity, and sex increased with ADI ($3317 [95% CI 1274 to 5360] for the most deprived vs least deprived ADI quintile, and overall p-value for ADI variable 0.009). The incremental cost for the most deprived vs least deprived ADI quintile was increasingly attenuated after separate adjustment for multimorbidity ($2407 [95% CI 416 to 4398], overall ADI p-value 0.066), frailty phenotype ($1962 [95% CI 11 to 3913], overall ADI p-value 0.22), or functional impairments ($1246 [95% CI -706 to 3198], overall ADI p-value 0.29). CONCLUSIONS: Total health care costs are higher for older community-dwelling Medicare beneficiaries residing in the most socioeconomically deprived areas compared to the least deprived areas. This association was not significant after accounting for the higher prevalence of phenotypic frailty and functional impairments among residents of socioeconomically deprived neighborhoods.

Factors associated with institutionalization among the oldest old: Results based on the nationally representative study 'old age in Germany (D80+)'.

OBJECTIVES: To examine the factors associated with institutionalization among individuals aged 80 years and over in Germany (total sample and stratified by sex). METHODS/DESIGN: We used data from the nationally representative 'Old Age in Germany (D80+)' (analytic sample: n = 9572 individuals), including individuals aged 80 years and over in Germany. Institutionalization (private living vs. institutionalization) served as an outcome measure. For the written interview, data collection took place from November 2020 to April 2021. Multiple logistic regressions of the overall sample (also stratified by sex) were applied. RESULTS: In the analytic sample, 10.2% (95% CI: 9.2%-11.3%) of the participants were institutionalized. The odds of being institutionalized were positively associated with being female (OR: 2.02, 95% CI: 1.08 to 3.80), being 90 years and over (compared to 80-84 years, OR: 1.67, 95% CI: 1.17 to 2.40), not being married (e.g., being single compared to being married: OR: 14.06, 95% CI: 6.73 to 29.37), higher education (e.g., high education compared to low education: OR: 1.88, 95% CI: 1.25 to 2.84), more favorable self-rated health (OR: 1.32, 95% CI: 1.07 to 1.62) and greater functional impairment (OR: 15.34, 95% CI: 11.91 to 19.74). Sex-stratified regressions were also conducted, mostly yielding similar results. CONCLUSION: Our study highlighted the role of several sociodemographic factors (particularly marital status, e.g., being single) and functional impairment for the risk of institutionalization among the oldest old in Germany. This study confirms findings in studies in younger samples that functional decline is the main factor associated with institutionalization. As functional decline may be modifiable, efforts to maintain functional abilities may be important. This knowledge is important for relevant groups (such as clinicians and policy-makers) because it may guide early intervention and prevention efforts, can help allocate healthcare resources effectively and shape policies to support independent living. Further insights using longitudinal data is recommended.

Clinical characteristics of 217 Chinese cases with depersonalization/derealization disorder.

Depersonalization/derealization disorder (DPD) is a prevalent yet inadequately understood clinical condition characterized by a recurrent or persistent sense of unreality. This study aims to provide insight into DPD through descriptive and comparative analyses involving a large group of Chinese participants. The socio-demographic details (age, gender proportion, education, occupational status, marital status), depersonalized and dissociative symptom characteristics (symptomatic factors or subscales of the Cambridge Depersonalization Scale and the Dissociative Experiences Scale), development trajectory (age of onset, potential precipitating factors, course characteristics), treatment history (duration of delayed healthcare attendance, duration of delayed diagnosis, previous diagnoses), and adverse childhood experiences of the DPD patients are presented. Comparisons of anxiety and depressive symptoms, alongside psychosocial functioning, between DPD participants and those diagnosed with generalized anxiety disorder, bipolar disorders, and major depressive disorder were conducted. The analysis highlights a higher male preponderance and early onset of DPD, symptomatology marked by derealization, notable impairment in psychosocial functioning, and prolonged periods of delayed healthcare attendance and diagnosis associated with symptom severity. Furthermore, noteworthy relationships between adverse childhood experiences and symptom levels were identified. The findings substantiate the view that DPD is a serious but neglected mental disorder, urging initiatives to improve the current condition of DPD patients.

Maladaptive daydreaming: A shortened assessment measure and its mental health correlates in a large United States sample.

BACKGROUND AND AIMS: Maladaptive Daydreaming (MD) is a suggested syndrome where individuals addictively engage in fanciful, narrative and emotional daydreaming for hours on end, often relying on stereotypical movements and music to facilitate the absorbed state. Many individuals suffering from MD to the point of clinically significant distress and functional impairment have advocated for its medicalization as a disorder. Maladaptive daydreamers exhibit high rates of psychopathology, but most studies were biased by self-selection. We developed a brief measure for efficient assessment of suspected MD and then administered it in a large non-selected US sample to gauge the significance of MD for public mental health. METHODS: Two previous datasets were utilized to develop the 5-item measure, labeled the Maladaptive Daydreaming Short Form (MD-SF5). Then, a large survey was conducted using the Qualtrics panel, administering the MD-SF5 alongside several validated measures of mental health to a general sample of panelists (N = 2512, 84.6% females, age M = 39.74, SD = 18.53, Race/Ethnicity: 66.3% White, 14.7% Black, 9.3% Hispanic, and 9.7% Other). RESULTS: The MD-SF5 showed good to excellent agreement with the existing measure. Generally, the new sample had high psychopathology rates. Suspected MD was associated with psychological distress, loneliness, psychotic experiences, heavy drinking, and suicidality. Notably, even after controlling for psychological distress, suspected maladaptive daydreamers were more than twice as likely to have recently attempted suicide (Odds Ratio = 2.44, 95% CI [1.44, 4.16], Wald = 10.86, p = .001). DISCUSSION AND CONCLUSIONS: MD harbors public health significance and can be screened for with a short self-report tool. Thus, MD should be addressed by mental health practitioners.

Dysregulated dendritic cells in sepsis: functional impairment and regulated cell death.

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. Studies have indicated that immune dysfunction plays a central role in the pathogenesis of sepsis. Dendritic cells (DCs) play a crucial role in the emergence of immune dysfunction in sepsis. The major manifestations of DCs in the septic state are abnormal functions and depletion in numbers, which are linked to higher mortality and vulnerability to secondary infections in sepsis. Apoptosis is the most widely studied pathway of number reduction in DCs. In the past few years, there has been a surge in studies focusing on regulated cell death (RCD). This emerging field encompasses various forms of cell death, such as necroptosis, pyroptosis, ferroptosis, and autophagy-dependent cell death (ADCD). Regulation of DC's RCD can serve as a possible therapeutic focus for the treatment of sepsis. Throughout time, numerous tactics have been devised and effectively implemented to improve abnormal immune response during sepsis progression, including modifying the functions of DCs and inhibiting DC cell death. In this review, we provide an overview of the functional impairment and RCD of DCs in septic states. Also, we highlight recent advances in targeting DCs to regulate host immune response following septic challenge.

Predictors of dementia among the oldest old: longitudinal findings from the representative "survey on quality of life and subjective well-being of the very old in North Rhine-Westphalia (NRW80+)".

BACKGROUND/AIMS: Our current study aimed to investigate the determinants of dementia among the oldest old using longitudinal data from a representative sample covering both community-dwelling and institutionalized individuals. METHODS/DESIGN: Longitudinal representative data were taken from the "Survey on quality of life and subjective well-being of the very old in North Rhine-Westphalia (NRW80+)" that surveyed community-dwelling and institutionalized individuals aged 80 years and above (n = 1,296 observations in the analytic sample), living in North Rhine-Westphalia (most populous state of Germany). The established DemTect was used to measure cognitive impairment (i.e., probable dementia). A logistic random effects model was used to examine the determinants of probable dementia. RESULTS: The mean age was 86.3 years (SD: 4.2 years). Multiple logistic regressions revealed that a higher likelihood of probable dementia was positively associated with lower education (e.g., low education compared to medium education: OR: 3.31 [95% CI: 1.10-9.98]), a smaller network size (OR: 0.87 [95% CI: 0.79-0.96]), lower health literacy (OR: 0.29 [95% CI: 0.14-0.60]), and higher functional impairment (OR: 13.45 [3.86-46.92]), whereas it was not significantly associated with sex, age, marital status, loneliness, and depressive symptoms in the total sample. Regressions stratified by sex were also reported. DISCUSSION: Our study identified factors associated with dementia among the oldest old. This study extends current knowledge by using data from the oldest old; and by presenting findings based on longitudinal, representative data (also including individuals residing in institutionalized settings). CONCLUSIONS: Efforts to increase, among other things, formal education, network size, and health literacy may be fruitful in postponing dementia, particularly among older women. Developing health literacy programs, for example, may be beneficial to reduce the burden associated with dementia.

Chronic pain and use of painkillers, healthcare services and long-term impairment among Syrian refugees: a cross-sectional study.

BACKGROUND: The global increase in forcibly displaced populations highlights the importance of understanding their health needs. Chronic pain is prevalent among refugees, poses significant personal and public health challenges, and complicates their integration into new home countries. Understanding refugees' pain post-migration and how it is being managed is crucial for ensuring adequate and timely interventions and fostering health equity. This paper explores the associations between pain levels and the use of painkillers, healthcare services, and long-term impairment among Syrian refugees with chronic pain, one year after their resettlement in Norway. METHODS: This cross-sectional study is based on survey data collected from 353 quota refugees in 2018-19, one year after resettlement in Norway. The primary outcomes were the use of painkillers, the use of healthcare services, and long-term impairment, according to reported chronic pain levels. Associations between these outcomes and chronic pain levels were studied using Poisson regression, adjusted by sociodemographic variables and trauma experience. RESULTS: Of the 353 adults included, 52% were women, and the median age was 36 years. A total of 5% reported very mild/mild, 10% moderate, and 12% strong/very strong chronic pain over the last four weeks. Significant associations were found between all chronic pain levels and use of non-prescription painkillers (adjusted relative risks (aRR) (95% CI)); mild (3.1 (2.0-4.7)), moderate (1.8 (1.1-2.8)), strong (1.7 (1.1-2.6)), and prescription painkillers; mild (4.6 (2.2-9.5)), moderate (5.6 (3.2-10.0)), strong (6.7 (3.9-11.3)), compared to those without chronic pain. Use of emergency rooms, specialist care, and hospitalization were significantly associated with strong chronic pain, with aRR (95% CI) of 2.0 (1.2-3.5), 3.9 (2.1-7.0) and 2.4 (1.3-4.4), respectively. Long-term impairment was strongly associated with chronic pain across all pain levels; mild (8.6 (5.6-13.49)), moderate (6.7 (4.3-10.5)) and strong (6.6 (4.3-10.4)). CONCLUSION: Despite their young age, more than a quarter of the Syrian refugees in our study reported chronic pain one year after resettlement in Norway. High levels of pain were related to the use of medication, healthcare services, and long-term impairment. Understanding the dynamics of pain among refugees is crucial to ensure adequate and timely management.

Predictive value of the five-repetition sit-to-stand test for outcomes after surgery for lumbar disc herniation: prospective study.

OBJECTIVE: It is unknown whether presence of pre-operative objective functional impairment (OFI) can predict post-operative outcomes in patients with lumbar disc herniation (LDH). We aimed to determine whether pre-operative OFI measured by the five-repetition sit-to-stand test (5R-STS) could predict outcomes at 12-months post-discectomy. METHODS: Adult patients with LDH scheduled for surgery were prospectively recruited from a Dutch short-stay spinal clinic. The 5R-STS time and patient reported outcome measures (PROMs) including Oswestry Disability Index, Roland-Morris Disability Questionnaire, Visual Analogue Scale (VAS) for back and leg pain, EQ-5D-3L health-related quality of life, EQ5D-VAS and ability to work were recorded pre-operatively and at 12-months. A 5R-STS time cut-off of ≥ 10.5 s was used to determine OFI. Mann-Whitney and Chi-square tests were employed to determine significant differences in post-operative outcomes between groups stratified by presence of pre-operative OFI. RESULTS: We recruited 134 patients in a prospective study. Twelve-month follow-up was completed by 103 (76.8%) patients. Mean age was 53.2 ± 14.35 years and 50 (48.5%) patients were female. Pre-operatively, 53 (51.5%) patients had OFI and 50 (48.5%) did not. Post-operatively, patients with OFI experienced a significantly greater mean change (p < 0.001) across all PROMs compared to patients without OFI, except leg pain (p = 0.176). There were no significant differences in absolute PROMs between groups at 12-months (all p > 0.05). CONCLUSIONS: The presence of OFI based on 5R-STS time does not appear to decrease a patient's likelihood of experiencing satisfactory post-operative outcomes. The 5R-STS cannot predict how a patient with LDH will respond to surgery at 12-month follow-up.

Identifying clusters of objective functional impairment in patients with degenerative lumbar spinal disease using unsupervised learning.

OBJECTIVES: The five-repetition sit-to-stand (5R-STS) test was designed to capture objective functional impairment (OFI), and thus provides an adjunctive dimension in patient assessment. It is conceivable that there are different subsets of patients with OFI and degenerative lumbar disease. We aim to identify clusters of objectively functionally impaired individuals based on 5R-STS and unsupervised machine learning (ML). METHODS: Data from two prospective cohort studies on patients with surgery for degenerative lumbar disease and 5R-STS times of ≥ 10.5 s-indicating presence of OFI. K-means clustering-an unsupervised ML algorithm-was applied to identify clusters of OFI. Cluster hallmarks were then identified using descriptive and inferential statistical analyses. RESULTS: We included 173 patients (mean age [standard deviation]: 46.7 [12.7] years, 45% male) and identified three types of OFI. OFI Type 1 (57 pts., 32.9%), Type 2 (81 pts., 46.8%), and Type 3 (35 pts., 20.2%) exhibited mean 5R-STS test times of 14.0 (3.2), 14.5 (3.3), and 27.1 (4.4) seconds, respectively. The grades of OFI according to the validated baseline severity stratification of the 5R-STS increased significantly with each OFI type, as did extreme anxiety and depression symptoms, issues with mobility and daily activities. Types 1 and 2 are characterized by mild to moderate OFI-with female gender, lower body mass index, and less smokers as Type I hallmarks. CONCLUSIONS: Unsupervised learning techniques identified three distinct clusters of patients with OFI that may represent a more holistic clinical classification of patients with OFI than test-time stratifications alone, by accounting for individual patient characteristics.

Reliability of self-measured objective functional impairment using the timed up and go test in patients with diseases of the spine.

BACKGROUND: Accurate assessment of a patient's functional status is crucial for determining the need for treatment and evaluating outcomes. Objective functional impairment (OFI) measures, alongside patient-reported outcome measures (PROMs), have been proposed for spine diseases. The Timed-Up and Go (TUG) test, typically administered by healthcare professionals, is a well-studied OFI measure. This study investigates whether patient self-measurement of TUG is similarly reliable. METHODS: In a prospective, observational study, patients with spinal diseases underwent two TUG assessments: one measured by a healthcare professional and one self-measured by the patient. Interrater reliability was assessed using the intraclass correlation coefficient (ICC) with a two-way random-effects model, considered excellent between 0.75 - 1.00. Paired t-tests directly compared both measurements. The impact of variables such as age, sex, disease type, symptom severity (via PROMs), comorbidities, and frailty on reliability was also analysed. RESULTS: Seventy-four patients were included, with a mean age of 62.9 years (SD 17.8); 29 (39.2%) were female. The majority (64.9%) were treated for degenerative disc disease. The lumbo-sacral region was most affected (71.6%), and 47.3% had previous surgeries. Patient self-measurement reliability was excellent (ICC 0.8740, p < 0.001), and the difference between healthcare professional (19.3 ± 9.4 s) and patient measurements (18.4 ± 9.7 s) was insignificant (p = 0.116). Interrater reliability remained high in patients > 65 years (ICC 0.8584, p < 0.001), patients with ASA grades 3&4 (ICC 0.7066, p < 0.001), patients considered frail (ICC 0.8799, p < 0.001), and in patients not using any walking aid (ICC 0.8012, p < 0.001). High symptom severity still showed strong reliability (ICC 0.8279, p < 0.001 for Oswestry Disability Index > 40; ICC 0.8607, p = 0.011 for Neck Disability Index > 40). CONCLUSIONS: Patients with spine diseases can reliably self-measure OFI using the TUG test. The interrater reliability between self-measurements and those by healthcare professionals was excellent across all conditions. These findings could optimize patient assessments, especially in resource-limited settings.

Identifying Functional Status Impairment in People Living With Dementia Through Natural Language Processing of Clinical Documents: Cross-Sectional Study.

BACKGROUND: Assessment of activities of daily living (ADLs) and instrumental ADLs (iADLs) is key to determining the severity of dementia and care needs among older adults. However, such information is often only documented in free-text clinical notes within the electronic health record and can be challenging to find. OBJECTIVE: This study aims to develop and validate machine learning models to determine the status of ADL and iADL impairments based on clinical notes. METHODS: This cross-sectional study leveraged electronic health record clinical notes from Mass General Brigham's Research Patient Data Repository linked with Medicare fee-for-service claims data from 2007 to 2017 to identify individuals aged 65 years or older with at least 1 diagnosis of dementia. Notes for encounters both 180 days before and after the first date of dementia diagnosis were randomly sampled. Models were trained and validated using note sentences filtered by expert-curated keywords (filtered cohort) and further evaluated using unfiltered sentences (unfiltered cohort). The model's performance was compared using area under the receiver operating characteristic curve and area under the precision-recall curve (AUPRC). RESULTS: The study included 10,000 key-term-filtered sentences representing 441 people (n=283, 64.2% women; mean age 82.7, SD 7.9 years) and 1000 unfiltered sentences representing 80 people (n=56, 70% women; mean age 82.8, SD 7.5 years). Area under the receiver operating characteristic curve was high for the best-performing ADL and iADL models on both cohorts (>0.97). For ADL impairment identification, the random forest model achieved the best AUPRC (0.89, 95% CI 0.86-0.91) on the filtered cohort; the support vector machine model achieved the highest AUPRC (0.82, 95% CI 0.75-0.89) for the unfiltered cohort. For iADL impairment, the Bio+Clinical bidirectional encoder representations from transformers (BERT) model had the highest AUPRC (filtered: 0.76, 95% CI 0.68-0.82; unfiltered: 0.58, 95% CI 0.001-1.0). Compared with a keyword-search approach on the unfiltered cohort, machine learning reduced false-positive rates from 4.5% to 0.2% for ADL and 1.8% to 0.1% for iADL. CONCLUSIONS: In this study, we demonstrated the ability of machine learning models to accurately identify ADL and iADL impairment based on free-text clinical notes, which could be useful in determining the severity of dementia.

Hepatic function markers as prognostic factors in patients with acute kidney injury undergoing continuous renal replacement therapy.

Acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT), secondary to cardiovascular disease and sepsis, is associated with high in-hospital mortality. Although studies have examined cardiovascular disease and sepsis in AKI, the association between AKI and hepatic functional impairment remains unclear. We hypothesized that hepatic function markers would predict mortality in patients undergoing CRRT. We included 1,899 CRRT patients from a multi-centre database. In Phase 1, participants were classified according to the total bilirubin (T-Bil) levels on the day of, and 3 days after, CRRT initiation: T-Bil < 1.2, 1.2 ≤ T-Bil < 2, and T-Bil ≥ 2 mg/dL. In Phase 2, propensity score matching (PSM) was performed to examine the effect of a T-Bil cutoff of 1.2 mg/dL (supported by the Sequential Organ Failure Assessment score); creating two groups based on a T-Bil cutoff of 1.2 mg/dL 3 days after CRRT initiation. The primary endpoint was total mortality 90 days after CRRT initiation, which was 34.7% (n = 571). In Phase 1, the T-Bil, aspartate transaminase (AST), alanine transaminase (ALT), and AST/ALT (De Ritis ratio) levels at CRRT initiation were not associated with the prognosis, while T-Bil, AST, and the De Ritis ratio 3 days after CRRT initiation were independent factors. In Phase 2, T-Bil ≥1.2 mg/dL on day 3 was a significant independent prognostic factor, even after PSM [hazard ratio: 2.41 (95% CI; 1.84-3.17), p < 0.001]. T-Bil ≥1.2 mg/dL 3 days after CRRT initiation predicted 90-day mortality. Changes in hepatic function markers in acute renal failure may enable stratification of high-risk patients.

Intensive care unit follow-up clinic activities: a scoping review.

The importance of ongoing post-discharge follow-up to prevent functional impairment in patients discharged from intensive care units (ICUs) is being increasingly recognized. Therefore, we conducted a scoping review, which included existing ICU follow-up clinic methodologies using the CENTRAL, MEDLINE, and CINAHL databases from their inception to December 2022. Data were examined for country or region, outpatient name, location, opening days, lead profession, eligible patients, timing of the follow-up, and assessment tools. Twelve studies were included in our review. The results obtained revealed that the methods employed by ICU follow-up clinics varied among countries and regions. The names of outpatient follow-up clinics also varied; however, all were located within the facility. These clinics were mainly physician or nurse led; however, pharmacists, physical therapists, neuropsychologists, and social workers were also involved. Some clinics were limited to critically ill patients with sepsis or those requiring ventilation. Ten studies reported the first outpatient visit 1-3 months after discharge. All studies assessed physical function, cognitive function, mental health, and the health-related quality of life. This scoping review revealed that an optimal operating format for ICU follow-up clinics needs to be established according to the categories of critically ill patients.

Impulsivity and Its Association with Depression and Anxiety in the Normal Egyptian Population Post COVID-19 Pandemic.

Background and Objectives: It is well known that depression, anxiety, and impulsiveness are interrelated; however, studies that have assessed their association with the coronavirus outbreak are scarce. Hence, our study aimed to evaluate the impulsivity incidence and its correlation with anxiety and depression following COVID-19 infection between November 2022 and June 2023. Materials and Methods: The 201 participants completed the Hamilton Depression Rating Scale (HDRS), Hamilton Anxiety Rating Scale (HAM-A), Sheehan Disability Scale (SDS), and short UPPS-P scales (urgency, premeditation, perseverance, sensation seeking, and positive urgency) to allow us to determine their anxiety and depression symptoms, functional impairment, and impulsivity, respectively. Results: Among our respondents, 22%, and 26.7% had moderate to severe anxiety and depression. The short UPPS-P scale significantly correlated with the HAM-A and HDRS scales. Participants with positive COVID-19 infection showed significantly higher functional impairment scores, especially in the work/study domain (mean (SD): 3.12 (2.2) vs. 2.43 (2.3); p = 0.037). COVID-19-related disruption significantly correlated with negative and positive urgency, HAM-A, HDRS, and the SDS total and subscales. Conclusions: Our findings showed a notable increase in anxiety, depression, and functional impairment among the population following COVID-19 infection. Our research highlights the correlation between impulsivity and the psychological distress experienced following the pandemic.

New Psychometric Evidence of the Grief Impairment Scale (GIS) in People Who Have Experienced the Death of a Loved One From a Network Psychometric Approach in Two Latin American Countries.

This study aimed to evaluate the psychometric properties of the Grief Impairment Scale (GIS) using a network psychometric model. A total of 1048 individuals from Peru and El Salvador participated. A network psychometric model was used to determine internal structure, reliability, and cross-country invariance. The results indicate that the GIS items were grouped into a single network structure through Exploratory Graph Analysis. Reliability was estimated by structural consistency, and it was found that when replicating the network structure within an empirical dimension, a single network structure was consistently obtained, and all items remained stable. Furthermore, the network structure was invariant, thus functioning similarly across the different country groups. In conclusion, the GIS presented solid psychometric evidence of validity based on its internal structure, reliability, and cross-country invariance. Therefore, the GIS is a psychometrically sound measure of functional impairment symptoms due to grief for Peruvian and Salvadoran individuals.

Cognitive Impairment in Tuberculous Meningitis.

BACKGROUND: Cognitive impairment is reported as a common complication in adult tuberculous meningitis (TBM), yet few studies have systematically assessed the frequency and nature of impairment. Moreover, the impact of impairment on functioning and medication adherence has not been described. METHODS: A cognitive test battery (10 measures assessing 7 cognitive domains) was administered to 34 participants with human immunodeficiency virus (HIV)-associated TBM 6 months after diagnosis. Cognitive performance was compared with that a comparator group of 66 people with HIV without a history of tuberculosis. A secondary comparison was made between participants with TBM and 26 participants with HIV 6 months after diagnosis of tuberculosis outside the central nervous system (CNS). Impact on functioning was evaluated, including through assessment of medication adherence. RESULTS: Of 34 participants with TBM, 16 (47%) had low performance on cognitive testing. Cognition was impaired across all domains. Global cognitive performance was significantly lower in participants with TBM than in people with HIV (mean T score, 41 vs 48, respectively; P < .001). These participants also had lower global cognition scores than those with non-CNS tuberculosis (mean global T score, 41 vs 46; P = .02). Functional outcomes were not significantly correlated with cognitive performance in the subgroup of participants in whom this was assessed (n = 19). CONCLUSIONS: Low cognitive performance following HIV-associated TBM is common. This effect is independent of, and additional to, effects of HIV and non-CNS tuberculosis disease. Further studies are needed to understand longer-term outcomes, clarify the association with treatment adherence, a key predictor of outcome in TBM, and develop context-specific tools to identify individuals with cognitive difficulties in order to improve outcomes in TBM.

When Functional Impairment Develops Early: Perspectives from Middle-Aged Adults.

BACKGROUND: Difficulty performing basic daily activities such as bathing and dressing ("functional impairment") affects more than 15% of middle-aged people, and this proportion is increasing. Little is known about the experiences and needs of individuals who develop functional impairment in middle age. OBJECTIVE: To examine the experiences and needs of adults who developed functional impairment in middle age. DESIGN: Qualitative study using semi-structured interviews. PARTICIPANTS: Forty patients aged 50-64 years who developed functional impairment in middle age, recruited from four primary care clinics in San Francisco. APPROACH: Interviews included open-ended questions about participants' daily life, ability to perform activities of daily living (ADLs), and needs related to functional impairment. We analyzed interviews using qualitative thematic analysis. KEY RESULTS: Interviews revealed several themes related to the psychosocial and physical impacts of developing functional impairment in middle age. Participants noted that losses associated with functional impairment, such as loss of independence, control, and social roles, caused conflict in their sense of identity. To cope with these losses, participants used strategies including acceptance, social comparison, adjusting standards, and engaging in valued life activities. Participants reflected on the intersection of their functional impairment with the aging process, noting that their impairments seemed premature compared to the more "natural" aging process in older adults. In terms of physical impacts, participants described how a lack of accommodations in the built environment exacerbated their impairments. While participants used behavioral strategies to overcome these challenges, unmet needs remained, resulting in downstream physical and psychological impacts including safety risks, falls, frustration, and fear. CONCLUSIONS: Unmet psychosocial and physical needs were common among middle-aged adults with functional impairment and led to negative downstream effects. Eliciting and addressing unmet needs may help mitigate downstream health consequences for this growing population, optimizing function and quality of life.
