Breast cancer continues to be a major health concern, and early detection is vital for enhancing survival rates. Magnetic resonance imaging (MRI) is a key tool due to its substantial sensitivity for invasive breast cancers. Computer-aided detection (CADe) systems enhance the effectiveness of MRI by identifying potential lesions, aiding radiologists in focusing on areas of interest, extracting quantitative features, and integrating with computer-aided diagnosis (CADx) pipelines.

Background: In patients with Systemic lupus erythematosus (SLE), osteonecrosis of various joints is a debilitating complication associated with the disease and its treatment, in which a considerable proportion of osteonecrosis may be asymptomatic. Recognizing the crucial role of early and timely detection, as well as appropriate management of asymptomatic osteonecrosis, in preventing joint destruction, we conducted a study to evaluate the prevalence of asymptomatic osteonecrosis in SLE patients who have already been diagnosed with symptomatic osteonecrosis. Additionally, we aimed to examine the relationship between proposed risk factors of osteonecrosis and the development of asymptomatic osteonecrosis.

. Modeling of the collimator-detector response (CDR) in single photon emission computed tomography (SPECT) reconstruction enables improved resolution and accuracy, and is thus important for quantitative imaging applications such as dosimetry. The implementation of CDR modeling, however, can become a computational bottleneck when there are substantial components of septal penetration and scatter in the acquired data, since a direct convolution-based approach requires large 2D kernels.

Background: Endometriosis, the most perplexing gynecologic condition, impairs the quality of life because it is usually accompanied by persistent severe acyclic pelvic pain and infertility as its two main symptoms. The majority economic burden of endometriosis is due to infertility and pelvic pain. Therefore, alleviating pelvic pain in patients with endometriosis is a necessity.

Article Synopsis
  • HTLV-1 is linked to serious health issues like Adult T-cell Leukemia/Lymphoma and HAM/TSP; thus, screening potential organ donors for the virus is vital due to high transmission risks, particularly in kidney transplant recipients.
  • A study at the Iranian Tissue Bank from 2014 to 2021 found that 3% of 3,814 potential organ/tissue donors tested positive for HTLV-1, with rates significantly dropping from 6% to 0.5% over the years.
  • Females showed a higher positivity rate (4%) than males (2%), and donors with brain death had a much lower infection rate (0.2%) compared to those with circulatory death (4%).

Background: Chronic kidney disease (CKD) affects 10% of the global population and leads to end-stage renal disease (ESRD). Hemodialysis is a common treatment for ESRD, but patients often have low carnitine levels, leading to dyslipidemia, a risk factor for cardiovascular disease and the leading cause of mortality. This study aimed to assess the effects of L-carnitine on lipid profiles in adult hemodialysis patients.

  • The study aimed to evaluate the effectiveness of adding cervical spine manual therapy (CMT) to conventional physical therapy (PT) for improving outcomes in patients with carpal tunnel syndrome (CTS).
  • Forty-eight patients were split into two groups: one received PT alone, while the other received PT plus CMT, with various assessments conducted at baseline, after treatment, and six months later.
  • Results indicated that the CMT group experienced significantly better improvements in pain levels and nerve function compared to the PT-only group, suggesting that combining CMT with PT could be a more effective treatment for CTS.
