Diagnosing pulmonary thromboembolism: Concerns and controversies

Pulmonary thromboembolism (PTE) is an important cause of mortality/morbidity even today despite advancement in clinical understanding as well as diagnostic facilities. Clinical diagnosis of PTE is often challenging because of nonspecific sign/symptoms. Adherence to clinical decision-making protocols and appropriate use of diagnostic modalities like computed tomography pulmonary angiography can resolve the diagnostic dilemma in most cases and help in the overall management of PTE. This article deals with various concerns as well as controversies surrounding accurate diagnosis of PTE as on date.     

Vascular and Chronological Age in Subjects with Erectile Dysfunction: A Cross-Sectional Study

IntroductionVascular age, as derived from the SCORE project algorithm for cardiovascular (CV) risk estimation, is an effective way for communicating CV risk. However, studies on its clinical correlates are scanty.AimTo evaluate if the difference between vascular and chronological age (Δage), in a population of subjects with erectile dysfunction (ED), can identify men with a worse risk profile.MethodsA consecutive series of 2,853 male patients attending the outpatient clinic for erectile dysfunction (ED) for the first time was retrospectively studied. Among them, 85.4% (n = 2,437) were free of previous MACE and were analyzed.Main Outcome MeasuresSeveral clinical, biochemical, and penile color Doppler parameters were studied. Vascular age was derived from the SCORE project algorithm, and the Δage was considered.ResultsHigher Δage is associated with several conventional (family history of CV diseases, hyperglycemia, elevated triglycerides, and increased prevalence of metabolic syndrome) and unconventional (severity of ED, frequency of sexual activity, alcohol abuse, lower education level, fatherhood, extramarital affairs, compensated hypogonadism, and low prolactin levels) risk factors. Δage is inversely related to penile color Doppler parameters, including flaccid and dynamic peak systolic velocity and flaccid acceleration (β = −0.125, −0.113, and −0.134, respectively, all P < 0.0001).ConclusionsIn subjects referring for ED without a personal history of CV events, Δage is associated with an adverse cardio-metabolic profile and worse penile color Doppler ultrasound parameters. Δage provides a simple method for identifying high-risk men that must undergo significant modification in their lifestyle and risk factors. In addition, it can be considered a simple, inexpensive, and safe surrogate marker of penile arterial damage.     

Effect of a Simple Exercise Program on Hospitalization-Associated Disability in Older Patients: A Randomized Controlled Trial

ObjectiveHospitalization-associated disability [HAD, ie, the loss of ability to perform ≥1 basic activities of daily living (ADLs) independently at discharge] is a frequent condition among older patients. The present study assessed whether a simple inpatient exercise program decreases HAD incidence in acutely hospitalized very old patients.DesignIn this randomized controlled trial (Activity in Geriatric Acute Care) participants were assigned to a control or intervention group and were assessed at baseline, admission, discharge, and 3 months thereafter.Setting and ParticipantsIn total, 268 patients (mean age 88 years, range 75–102) admitted to an acute care for older patients unit of a public hospital were randomized to a control (n = 125) or intervention (exercise) group (n = 143).MethodsBoth groups received usual care, and patients in the intervention group also performed simple supervised exercises (walking and rising from a chair, for a total duration of ∼20 minutes/day). We measured ADL function (Katz index) and incident HAD at discharge and after 3 months (primary outcome) and Short Physical Performance Battery, ambulatory capacity, number of falls, rehospitalization, and death during a 3-month follow-up (secondary outcomes).ResultsMedian duration of hospitalization was 7 days (interquartile range 4 days). The intervention group had a lower risk of HAD with reference to both baseline [odds ratio (OR) 0.36; 95% confidence interval (CI) 0.17–0.76, P = .007] and admission (OR 0.29; 95% CI 0.10–0.89, P = .030). A trend toward an improved ADL function at discharge vs admission was found in the intervention group compared with controls (OR 0.32; 95% CI ‒0.04 to 0.68; P = .083). No between-group differences were noted for the other endpoints (all P > .05).Conclusion and ImplicationsA simple inpatient exercise program decreases risk of HAD in acutely hospitalized, very old patients.     

Resources for Enhancing Alzheimer's Caregiver Health in Vietnam (REACH VN): Exploratory Analyses of Outcomes of a Cluster Randomized Controlled Trial to Test the Feasibility and Preliminary Efficacy of a Family Dementia Caregiver Intervention in Vietnam

ObjectiveFew support services and caregiving interventions exist to support family caregivers in low- and middle-income countries (LMIC). This paper presents exploratory analyses of outcomes of Resources for Enhancing Alzheimer's Caregiver Health in Vietnam (REACH VN).MethodsA cluster randomized controlled trial (RCT) was conducted in Soc Son, a semi-rural area in Hanoi. Nine clusters with 60 caregivers were randomized to either an enhanced control group or REACH VN, an in-home, multicomponent, family caregiver support intervention delivered over two to three months. Outcomes were assessed at baseline and three months.ResultsCaregivers in the intervention group experienced a significantly greater reduction in frustration levels compared to those in the control group. There were differences in other outcomes (e.g., care recipient problem behaviors and associated caregiver bother) favoring the intervention condition that did not reach statistical significance.ConclusionWe found additional evidence that REACH VN is a promising intervention to improve family caregiver outcomes in Vietnam.     

Relationship between Neurological Deterioration and Blood Pressure/Heart Rate Variability in Patients with Acute Cerebral Infarction

ObjectivesNeurological deterioration (ND) during hospitalization is an independent predictor of poor prognosis after stroke. Risk factors affecting early ND within 48 h post stroke have been intensively investigated, while few data are available on those for late ND after transfer to a wheelchair. Therefore, it was investigated whether hemodynamic factors may affect the late ND during hospitalization.Materials and methodsA retrospective study was conducted on 135 patients with atherothrombotic or cardiogenic cerebral infarction who were admitted to our hospital between April 1st, 2014 and July 31st, 2017. During hospitalization, average, maximum, and minimum values were determined for systolic blood pressure (sBP), diastolic BP (dBP), and heart rate (HR), respectively.135 patients were classified into two groups; ND (+) group, in which modified Barthel index score at the time of transfer to a wheelchair showed five points or more decrease between wheelchair transfer and discharge, and ND (?) group, which did not. Vital indices were compared between the two groups and subjected to ROC-curve analysis.ResultsThe ND (+) group included 32 patients, and the ND (?) 103. Significant differences were found between the groups in four items; sBPmin (p = 0.029), dBPmin (p = 0.019), HRave (p = 0.028), and HRmax (p < 0.01). The ND (+) group showed lower sBPmin and dBPmin, and higher HRave and HRmax than the ND (?) group.ConclusionsLate ND after transfer to a wheelchair is related to the vital indices during hospitalization and should be cautiously managed to prevent late ND
