Community-dwelling older adults who are low-income and disabled weathering financial challenges

Despite interventions aiming to improve outcomes among older adults experiencing financial challenges, the challenges and strategies employed to handle them are poorly understood. This study examined the experiences of financial challenges among low-income adults aged ≥65 years. Eleven semi-structured interviews were analyzed using thematic analyses. An overarching theme was “I guess it balances”, capturing attempts to maintain hope and proactively address challenges despite stress, uncertainty and limitations. Balancing was demonstrated within four domains, including cognitive bandwidth (“think a lot” versus “I don't dwell on that”), emotional experience (“depressing” versus “be thankful”), learned resilience (“that was a shock” versus “there's always a way”), and meeting daily needs (“we learned to do without” versus “take a dollar and stretch it”). Participants described being weathered by challenges and using predominately high-effort coping strategies to weather the challenges. These findings call for strengthening the safety net for older adults facing financial challenges.     

Direct and indirect costs of heart failure in relation to diabetes status - A nationwide study

Background and aimHeart failure (HF) and diabetes mellitus (DM) are burdensome chronic diseases with high lifetime risks and numerous studies indicate associations between HF and DM. The objective of this study was to investigate the direct and indirect costs of HF patients with and without DM.Methods and resultsPatients with a first-time diagnosis of HF from 1998 to 2016 were identified through nationwide Danish registries and stratified according to DM status into HF with or without DM. The economic healthcare cost analysis was based on both direct costs, including hospitalization, procedures, medication and indirect costs including social welfare and lost productivity. The economic burden was investigated prior to, at, and following diagnosis of HF. Patients with concomitant HF and DM were younger (median age 74 vs. 77), had more comorbidities and fewer were female as compared to patients with HF but without DM. The socioeconomic burden of concomitant HF and DM compared to HF alone was substantially higher; 45% in direct costs (€16,237 vs. €11,184), 35% in home care costs (€3123 vs. €2320), 8% in social transfer income (€17,257 vs. €15,994) and they had 27% lower income (€10,136 vs. €13,845). The economic burden peaked at year of diagnosis, but the difference became increasingly pronounced in the years following the HF diagnosis.ConclusionPatients with concomitant HF and DM had a significantly higher economic burden compared to patients with HF but without DM.

Identification of Sleep Apnea Severity Based on Deep Learning from a Short-term Normal ECG

BackgroundThis paper proposes a novel method for automatically identifying sleep apnea (SA) severity based on deep learning from a short-term normal electrocardiography (ECG) signal.MethodsA convolutional neural network (CNN) was used as an identification model and implemented using a one-dimensional convolutional, pooling, and fully connected layer. An optimal architecture is incorporated into the CNN model for the precise identification of SA severity. A total of 144 subjects were studied. The nocturnal single-lead ECG signal was collected, and the short-term normal ECG was extracted from them. The short-term normal ECG was segmented for a duration of 30 seconds and divided into two datasets for training and evaluation. The training set consists of 82,952 segments (66,360 training set, 16,592 validation set) from 117 subjects, while the test set has 20,738 segments from 27 subjects.ResultsF1-score of 98.0% was obtained from the test set. Mild and moderate SA can be identified with an accuracy of 99.0%.ConclusionThe results showed the possibility of automatically identifying SA severity based on a short-term normal ECG signal.     

Polygenic risk scores and risk-stratified breast cancer screening: Familiarity and perspectives of health care professionals

PurposeHealth care professionals are expected to take on an active role in the implementation of risk-based cancer prevention strategies. This study aimed to explore health care professionals’ (1) self-reported familiarity with the concept of polygenic risk score (PRS), (2) perceived level of knowledge regarding risk-stratified breast cancer (BC) screening, and (3) preferences for continuing professional development.MethodsA cross-sectional survey was conducted using a bilingual—English/French—online questionnaire disseminated by health care professional associations across Canada between November 2020 and May 2021.ResultsA total of 593 professionals completed more than 2 items and 453 responded to all questions. A total of 432 (94%) participants were female, 103 (22%) were physicians, and 323 (70%) were nurses. Participants reported to be unfamiliar with (20%), very unfamiliar (32%) with, or did not know (41%) the concept of PRS. Most participants reported not having enough knowledge about risk-stratified BC screening (61%) and that they would require more training (77%). Online courses and webinar conferences were the preferred continuing professional development modalities.ConclusionThe study indicates that health care professionals are currently not familiar with the concept of PRS or a risk-stratified approach for BC screening. Online information and training seem to be an essential knowledge transfer modality.     

Use of antipsychotics in elderly patients with dementia: Do atypical and conventional agents have a similar safety profile?

Pharmacological treatment of dementia addresses two main clinical features of the disease: cognitive deterioration with predominantly memory loss and behavioural and psychological symptoms (BPSD). While cholinesterase inhibitors are recommended in an attempt to delay memory loss and disability, what should be considered the most appropriate pharmacological treatment for BPSD has remained questionable. Antipsychotic medications, conventional and atypical agents, have been increasingly utilized in clinical practice but only a small number of clinical studies have investigated their relative cost–benefit ratio. This review focuses on the safety of atypical and conventional antipsychotics when used in patients with BPSD. Overall, atypical and conventional antipsychotics are associated with a similarly increased risk for all-cause mortality and cerebrovascular events. Relative to atypical agents users, patients being treated with conventional antipsychotics have an increased incidence of cardiac arrhythmias and extrapyramidal symptoms. Conversely, users of atypical antipsychotics are exposed to an increased risk of venous thromboembolism and aspiration pneumonia. Also, metabolic effects (i.e. increased risk of diabetes, weight gain) have consistently been documented in clinical studies with atypical antipsychotics, although this effect tends to be attenuated with advancing age and in elderly patients with dementia. Antipsychotics, both conventional and atypical, should be used with caution only when nonpharmacologic approaches have failed to adequately control BPSD. More effective interventions are necessary to improve postmarket drug safety in vulnerable populations.     

Pathologic response rates for breast cancer stages as a predictor of outcomes in patients receiving neoadjuvant chemotherapy followed by breast-conserving surgery

PurposeTo determine easy-to-use predictors of overall survival (OS), locoregional recurrence (LRR), and distant metastasis (DM) in patients with breast invasive ductal carcinoma (IDC) receiving neoadjuvant chemotherapy (NACT) followed by breast-conserving surgery (BCS), we obtained pathologic response rates (PRRs) for combined primary and nodal diseases (American Joint Committee on Cancer [AJCC] stages) from clinical and pathologic reports, and we used these as predictors.Patients and methodsWe enrolled patients with IDC who had received NACT followed by BCS. Cox regression analysis was used to calculate hazard ratios (HRs) and confidence intervals (CIs) for the patients’ PRRs; other independent predictors were controlled for or stratified in the analysis.ResultsWe analyzed 1047 patients with IDC (611, 260, and 176 patients in clinical stages IIB, IIIA, and IIIB-C, respectively) receiving NACT and BCS. After multivariate Cox regression analyses, the adjusted HRs (aHRs; 95% CI) in patients with pathologic complete response (ypT0N0) were 0.26 (0.13–0.56), 0.36 (0.15–0.85), and 0.15 (0.08–0.31) for all-cause mortality, LRR, and DM, respectively. The aHRs (95% CI) in patients with downstaging of AJCC stages were 0.55 (0.35–0.89), 0.91 (0.62–0.96), and 0.63 (0.43–0.91) for all-cause mortality, LRR, and DM, respectively. The aHRs (95% CI) in patients with upstaging of AJCC stages were 1.77 (1.06–2.24), 1.08 (1.03–1.82), and 1.19 (1.07–2.01) for all-cause mortality, LRR, and DM, respectively.ConclusionThe impacts of AJCC-stage PRRs are useful predictive tools and strong predictors for OS, LRR, and DM in patients with breast IDC receiving NACT followed by BCS.     

Dyslipidemia and coronary artery calcium: From association to development of a risk-prediction nomogram

Background and aimsThe associations between dyslipidemia and coronary artery calcium (CAC) are controversial. We investigated their cross-sectional relationships and developed a predictive scoring system for prognostically significant coronary calcification (PSCC).Methods and resultsThis study evaluated the lipid profiles and the CAC score (CACS) measured through multidetector computed tomography (MDCT) among Taiwanese adult patients in a tertiary hospital between 2011 and 2016. Patients with CACS higher than 100 were classified as having PSCC. Dyslipidemia for each lipid component was defined based on the clinical cutoffs or the use of the lipid-lowering agents. Multivariable logistic regression was used to assess the association between dyslipidemia and PSCC and the model performance was assessed using calibration plot, discrimination, and a decision curve analysis.Of the 3586 eligible patients, 364 (10.2%) had PSCC. Increased age, male sex, higher body mass index (BMI), and higher level of triglyceride (TG) were associated with PSCC. The adjusted odds ratios (95% confidence intervals) of PSCC was 1.15 (0.90–1.47) for dyslipidemia defined by total cholesterol (TC) ≥200 mg/dL, 1.06 (0.83–1.35) for low-density-lipoprotein-cholesterol (LDL-C) ≥130 mg/dL, and 1.36 (1.06–1.75) for TG ≥ 200 mg/dL. The positive association between TG ≥ 200 mg/dL and PSCC was not modified by sex. Incorporating hypertriglyceridemia did not significantly improve the predictive performance of the base model comprising of age, sex, BMI, smoking, hypertension, diabetes, estimated glomerular filtration rate, and fasting glucose.ConclusionsHypertriglyceridemia was significantly associated with the prevalent odds of PSCC. Our proposed predictive model may be a useful screening tool for PSCC.
