ive rotation of different exercises (i.e., high frequency of change), may actually hinder muscular adaptations.

This feasibility study aimed to use optimized virtual contrast enhancement through generative adversarial networks (GAN) to reduce the dose of iodine-based contrast medium (CM) during abdominal computed tomography (CT) in a large animal model.

Multiphasic abdominal low-kilovolt CTs (90 kV) with low (low CM, 105 mgl/kg) and normal contrast media doses (normal CM, 350 mgl/kg) were performed with 20 healthy Göttingen minipigs on 3 separate occasions for a total of 120 examinations. These included an early arterial, late arterial, portal venous, and venous contrast phase. One animal had to be excluded because of incomplete examinations. Three of the 19 animals were randomly selected and withheld for validation (18 studies). Subsequently, the GAN was trained for image-to-image conversion from low CM to normal CM (virtual CM) with the remaining 16 animals (96 examinations). For validation, region of interest measurements were performed in the abdominal aorta, inferior vena cava, portal vein, liver parenchyma, aexaminers to identify the normal CM data as such in median in 91% of the cases.

In this feasibility study, it could be demonstrated in an experimental setting with healthy Göttingen minipigs that the amount of CM for abdominal CT can be reduced by approximately 70% by GAN-based contrast enhancement with satisfactory image quality.

A consecutive sample of cancer patients and oncology ward nurses at a hospital in Gaborone, Botswana, was used. Patients' symptom burden was assessed using the Memorial Symptom Assessment Scale-Short Form and the Visual Analog Scale-Pain, and patient- and nurse-acceptability data were assessed using the Client Satisfaction Questionnaire and the Intervention Rating Profile. Rates of participation, assessment length of time, and rates of completed Memorial Symptom Assessment Scale-Short Form and Visual Analog Scale-Pain determined feasibility. The sample included 124 patients (female, 84) and 20 nurses (female, 14). The mean (SD) Client Satisfaction Questionnaire score was 30.1 (2.8; minimum-maximum, 19-32), and the mean (SD) Intervention Rating Profile score was 86.8 (4.3; minimum-maximum, 74-90). There was a significant difference in the scores of the Intervention Rating Profile between preassessment (mean [SD], 80.1 [6.0]) and postassessment (mean [SD], 86.8 [4.3]; t19 = -4.853, P less then .001). All patient participants (100%) completed assessments. The routine nursing assessment was acceptable to and feasible among patients and nurses. Nurses can integrate validated instruments into routine nursing assessment to determine patients' symptom burden for quick referrals to palliative care.

We propose a method of quantitatively measuring drug-induced microvascular volume changes, as well as drug-induced changes in blood oxygenation using calibrated blood oxygen level-dependent magnetic resonance imaging (MRI). We postulate that for MRI signals there is a contribution to R2* relaxation rates from static susceptibility effects of the intravascular blood that scales with the blood volume/magnetic field and depends on the oxygenation state of the blood. These may be compared with the effects of an intravascular contrast agent. With 4 R2* measurements, microvascular blood volume (MBV) and tissue oxygenation changes can be quantified with the administration of a vasoactive drug.

The protocol examined 12 healthy rats in a prospective observational study. R2* maps were acquired with and without infusion of adenosine, which increases microvascular blood flow, or dobutamine, which increases myocardial oxygen consumption. In addition, R2* maps were acquired after the intravenous administration of a moncontrast agents.

Our results demonstrate the ability to quantify microvascular volume and oxygenation changes using calibrated blood oxygen level-dependent MRI, and we demonstrate different responses of adenosine and dobutamine. This method has clinical potential in examining microvascular disease in various disease states without the administration of radiopharmaceuticals or gadolinium-based contrast agents.Predialytic hyponatremia is associated with poor outcome in hemodialysis patients. Hypotonic hyponatremia is the most frequently encountered disorder reflecting mixed disorders combining extracellular fluid overload and free water excess, resulting from the interplay of intermittency of dialysis and diet observance, and likely precipitated by an acute or subacute illness. In this context, hyponatremia requires to be detected and worked up to identify and cure the cause. In this clinical case report, we describe preliminary results of using an online biosensor on a dialysis machine that provides automated predialysis plasma sodium concentration derived from dialysate conductivity measurements. Based on this biosensor, within a 5 year time frame, 11 patients out of more than 130 maintenance hemodialysis patients and over 40,000 dialysis sessions were identified with episodes of predialysis hyponatremia (≤135 mmol/l). In all patients, hyponatremic episodes were indicative of a severe underlying illness associated with fluid overload leading to plasma hypotonicity. Automated online predialysis plasma sodium concentration measurement offers an innovative, reliable, and cost-free tool that permits to detect hyponatremia as marker of an underlying illness development in dialysis patients. The value of this tool in supporting clinical decision-making deserves further studies in a large dialysis population.This retrospective study included children aged ≤18 years who had durable ventricular assist devices (VADs) as a bridge to transplantation from the United Network Organ Sharing (UNOS) database between 2011 and 2020. We evaluated 90-day waitlist mortality and 1-year posttransplant mortality after VAD implantation in children stratified by race/ethnicity Black, White, and Others. The VAD was used in a higher proportion of Black children listed for heart transplantation (HT) (26%) versus Other (25%) versus White (22%); p less then 0.01. Black children had Medicaid health insurance coverage (67%) predominantly at the time of listing for HT. There was no significant overall difference in waitlist survival among the three groups supported with VAD at the time of listing (log-rank p = 0.4). On the other hand, the 90-day waitlist mortality after the VAD implantation at listing and while listed was the lowest among Black (6%) compared with White (13%) and Other (14%) (p less then 0.01). selleck chemicals The multivariate regression analysis showed that Other race (hazard ratio [HR], 2.29; p less then 0.01), Black race (HR, 2.13; p less then 0.01), use of mechanical ventilation (HR, 1.72; p = 0.01), and Medicaid insurance (HR, 1.54; p = 0.04) were independently associated with increased 1-year posttransplant mortality. In conclusion, Black children had more access to durable VAD support than White children. The 90-day waitlist mortality was significantly lower in Black children compared with White and Other after VAD implantation. However, Black and Other racial/ethnic children with VAD at transplant had higher 1-year posttransplant mortality than White children. Future studies to elucidate the reasons for these disparities are needed.

Mohs micrographic surgery (MMS)-associated anxiety is an important issue that remains poorly discussed. Identifying risk factors for MMS-associated anxiety will better equip physicians to manage patients' preoperative anxiety and result in improved patient satisfaction and outcomes.

This study aims in identification of risk factors that may play a role in MMS-associated anxiety among patients with nonmelanoma skin cancer.

A cross-sectional case series was conducted among MMS patients collect information on patient demographics and surgical locations and to measure perioperative anxiety and quality of life (QoL). In addition, adjusted linear and logistic regression analyses were performed to identify potential risk factors that predict MMS-associated anxiety.

Significant increases in perioperative anxiety were associated with the eyelid area compared with the noneyelid facial area and nonfacial area ( p ≤ .05). Patients with graduate degrees exhibited less anxiety compared with ones who received less education ( p ≤ .05). Higher perioperative anxiety was associated with a greater impact on QoL ( p ≤ .05).

This study identified that surgical location and the patient's educational level are 2 critical predicting factors for perioperative anxiety. Furthermore, perioperative anxiety could negatively affect a patient's quality of life and warrants further investigation into effective management.

Reducing the treatment gap for mental health in low- and middle-income countries is a high priority. Even with treatment, adherence to antipsychotics is rather low. Our integrated intervention package significantly improved medication adherence within 6 months for villagers with schizophrenia in resource-poor communities in rural China. However, considering the resource constraint, we need to test whether the effect of those behavior-shaping interventions may be maintained even after the suspension of the intervention.

The aim of this study is to explore the primary outcome of adherence and other outcomes at an 18-month follow-up after the intervention had been suspended.

In a 6-month randomized trial, 277 villagers with schizophrenia were randomized to receive either a government community mental health program (686 Program) or the 686 Program plus Lay health supporters, e-platform, award, and integration (LEAN), which included health supporters for medication or care supervision, e-platform access forher alternative interpretations.

The simple community-based LEAN intervention could not continually improve adherence and reduce the rehospitalization of people with schizophrenia. Our study inclined to suggest that prompts for medication may be necessary to maintain medication adherence for people with schizophrenia, although we cannot definitively exclude other alternative interpretations.

Despite the increasing availability of telemedicine video visits during the COVID-19 pandemic, older adults have greater challenges in getting care through telemedicine.

We aim to better understand the barriers to telemedicine in community-dwelling older adults to improve the access to and experience of virtual visits.

We conducted a mixed methods needs assessment of older adults at two independent living facilities (sites A and B) in Northern California between September 2020 and March 2021. Voluntary surveys were distributed. Semistructured interviews were then conducted with participants who provided contact information. Surveys ascertained participants' preferred devices as well as comfort level, support, and top barriers regarding telephonic and video visits. Qualitative analysis of transcribed interviews identified key themes.

Survey respondents' (N=249) average age was 84.6 (SD 6.6) years, and 76.7% (n=191) of the participants were female. At site A, 88.9% (111/125) had a bachelor's degree or beyond, and 99.
