Only 6% cited family or financial reasons and 10% cited recurrence concerns. Among women planned for surgery, 65.71% had not considered BR. When questioned, 25 (12.88%) felt influenced by cost, 102 (52.58%) felt they did not need it, and 20 (10.31%) were worried it would affect treatment.

Our study shows high awareness regarding BR, but only 27.89% women opt for BR independent of economic issues. We recommend all patients should be counseled about the reconstructive options when their MRM is planned.

As frontline workers facing the COVID-19 pandemic, healthcare providers should be well-prepared to fight the disease and prevent harm to their patients and themselves. Our study aimed to evaluate the knowledge, attitude, and practice of oncologists in response to the COVID-19 pandemic and its impact on them.

A cross-sectional study was conducted using a validated questionnaire disseminated to oncologists by SurveyMonkey. The tool had 42 questions that captured participants' knowledge, attitude, and practice; their experiences; and the pandemic's impact on various aspects of their lives. Participants from Middle East and North African countries, Brazil, and the Philippines completed the electronic survey between April 24 and May 15, 2020.

Of the 1,010 physicians who participated in the study, 54.75% were male and 64.95% were medical or clinical oncologists. this website The level of knowledge regarding the prevention and transmission of the virus was good in 52% of participants. The majority (92%) were worried about mplemented to mitigate the negative impact and prepare oncologists to manage future crises with more efficiency and resilience.Volunteering has been identified as a potential mechanism for improving the psychosocial health of older adults. Utilizing a randomized controlled trial approach, the present study assessed the extent to which commencing volunteering can improve psychosocial health outcomes for older people. Fully retired Australian adults aged 60+ years (N= 445) were assessed at baseline and allocated to either the intervention or control arms of the trial. Those in the intervention condition were asked to participate in at least 60 min of formal volunteering per week for 6 months. Per-protocol analyses were conducted comparing psychosocial outcomes for those who complied with the intervention condition (n= 73) to outcomes for those who complied with the control condition (n= 112). Those who complied with the intervention condition demonstrated significant improvements in life satisfaction, purpose in life, and personal growth scores over a 12-month period relative to those in the control condition who did no volunteering. Findings provide evidence of a causal relationship between commencing volunteering and improvements in psychosocial health among older adults and indicate that encouraging participation in this activity could constitute an effective healthy aging intervention.

A new Bayesian penalized likelihood reconstruction algorithm for positron emission tomography (PET) (Q.Clear) is now in clinical use for fludeoxyglucose (FDG) PET/CT. However, experience with non-FDG tracers and in special patient populations is limited. This pilot study aims to compare Q.Clear to standard PET reconstructions for

F sodium fluoride (

F-NaF) PET in obese patients.

30 whole body

F-NaF PET/CT scans (10 patients with BMI 30-40 Kg/m

and 20 patients with BMI >40 Kg/m

) and a NEMA image quality phantom scans were analyzed using ordered subset expectation maximization (OSEM) and Q.Clear reconstructions methods with B400, 600, 800 and 1000. The images were assessed for overall image quality (IQ), noise level, background soft tissue, and lesion detectability, contrast recovery (CR), background variability (BV) and contrast-to-noise ratio (CNR) for both algorithms.

CNR for clinical cases was higher for Q.Clear than OSEM (

< 0.05). Mean CNR for OSEM was (21.62 ± 8.9), and for Q.Clear Bayesian penalized likelihood reconstruction with18F-NaF PET improves overall IQ in obese patients.

Left-ventricular (LV) strain measurements with the Displacement Encoding with Stimulated Echoes (DENSE) MRI sequence provide accurate estimates of cardiotoxicity damage related to chemotherapy for breast cancer. This study investigated an automated and supervised deep convolutional neural network (DCNN) model for LV chamber quantification before strain analysis in DENSE images.

The DeepLabV3 +DCNN with three versions of ResNet-50 backbone was designed to conduct chamber quantification on 42 female breast cancer data sets. The convolutional layers in the three ResNet-50 backbones were varied as non-atrous, atrous and modified, atrous with accuracy improvements like using Laplacian of Gaussian filters. Parameters such as LV end-diastolic diameter (LVEDD) and ejection fraction (LVEF) were quantified, and myocardial strains analyzed with the Radial Point Interpolation Method (RPIM). Myocardial classification was validated with the performance metrics of accuracy, Dice, average perpendicular distance (APD) andd validated for LV chamber quantification and strain analysis in cardiotoxicity detection.

A novel deep-learning technique for segmenting DENSE images was developed and validated for LV chamber quantification and strain analysis in cardiotoxicity detection.

To investigate the impact of total variation regularized expectation maximization (TVREM) reconstruction on the image quality of

Ga-PSMA-11 PET/CT using phantom and patient data.

Images of a phantom with small hot sphere inserts and 20 prostate cancer patients were acquired with a digital PET/CT using list-mode and reconstructed with ordered subset expectation maximization (OSEM) and TVREM with seven penalisation factors between 0.01 and 0.42 for 2 and 3 minutes-per-bed (m/b) acquisition. The contrast recovery (CR) and background variability (BV) of the phantom, image noise of the liver, and SUV

of the lesions were measured. Qualitative image quality was scored by two radiologists using a 5-point scale (1-poor, 5-excellent).

The performance of CR, BV, and image noise, and the gain of SUV

was higher for TVREM 2 m/b groups with the penalization of 0.07 to 0.28 compared to OSEM 3 m/b group (all

< 0.05). The image noise of OSEM 3 m/b group was equivalent to TVREM 2 and 3 m/b groups with a penalization of 0.
