Background/aim: Elderly patients with early-stage breast cancer have potentially been underrepresented in clinical trials. Thus, treatment strategies for a minority of elderly patients with hormone receptor (HR)-negative breast cancer may be inadequately informed.

Patients And Methods: We retrospectively reviewed 126 patients with HR-negative breast cancer aged ≥65 years.

Objectives: (1) To describe and compare cardiovascular and cardiometabolic disease risk scores using three existing risk calculators: Framingham Risk Score (FRS), American Heart Association (AHA) and Metabolic Syndrome Severity Score (MSSS) in Veterans with spinal cord injury and disorders (SCI/D); (2) To examine level of agreement between risk scores derived from three different risk scoring systems; and (3) To investigate whether the agreement among these methods is different for Veterans with Tetraplegia versus Paraplegia.

Design: Retrospective chart review.

Methods: Electronic medical records of 194 Veterans with SCI/D who were seen at the VAPAHCS SCI/D Center between August 2004 and June 2022 were reviewed.

Background: Cervical spinal cord injury (SCI) has a devastating effect on health and independence. Restoring upper extremity function is a top priority and can be accomplished by tendon transfer (TT) and nerve transfer (NT) surgery. The purpose of this prospective comparative study was to assess long-term changes in upper extremity function between surgical (TT or NT) and nonsurgical groups through a comprehensive mixed-methods approach.

Context/objective: To assess short-term changes in health outcomes in people with cervical-level spinal cord injury (SCI) who underwent upper extremity (UE) reconstruction via either novel nerve transfer (NT) or traditional tendon transfer (TT) surgery with individuals who did not undergo UE surgical reconstruction.

Design: Prospective, comparative cohort pilot study.

Participants: 34 participants with cervical SCI met the following inclusion criteria: age 18 or older, greater than 6 months post-injury, and mid-cervical level SCI American Spinal Injury Association Impairment Scale (AIS) A, B or C.

Article Synopsis
  • Nerve transfer (NT) and tendon transfer (TT) surgeries can significantly improve hand function and independence for those with cervical spinal cord injuries, but caregivers face their own challenges in the process.
  • A study explored the experiences of these caregivers, focusing on their daily activities, mental health, and feelings of burden before and after their loved ones underwent surgery.
  • Results showed that while surgeries offered hope, caregivers felt an increased burden post-surgery, especially after TT, and highlighted the need for healthcare providers to better support caregivers throughout the surgical and recovery process.

Introduction: People with cervical spinal cord injury (SCI) identify improving upper extremity (UE) function as a top priority. In addition to comprehensive rehabilitation, UE surgeries, including nerve and tendon transfers, enhance function. However, barriers exist to disseminating information about surgical options to enhance UE function.

Background: Gerome and Labroy (Agavaceae) is a religious and ornamental perennial plant with highly valued medicinal usage in Nigeria. Sansevieria liberica is used in the management of malarial fever. The ease of development of resistance to available antimalarial drugs has resulted in increased clinical failure and mortality.

Ethnopharmacological Relevance: Malaria remains one of the most prevalent infectious diseases in tropical regions of the world, particularly in sub-Saharan Africa, where it remains epidemiologically holoendemic. The absence of effective vaccines and Plasmodium resistance to antimalarial drugs have been the major challenges to malaria control measures. An alternative strategy could be the application of validated and standardized herbal formulations.

Post-surgery immunomodulation, including reduced natural killer cell cytotoxicity (NKCC), is recognized as a predictor of poor outcomes in patients following cancer surgery. The present study investigated direct immunomodulation via ketamine as an anesthetic adjuvant in patients undergoing cancer surgery. The present non-double blinded randomized trial was conducted at Hirosaki University Hospital with 60 patients who underwent minimally invasive robotic radical prostatectomy to minimize the immunomodulation due to surgical stress.

Background: Malaria is a leading cause of death in Nigeria.

Aim: Antimalarial activity of stem bark was evaluated in mice with an objective to finding scientific evidence for its use as antimalarial remedy in South-east Nigeria.

Methods: Antiplasmodial activities of hydro-methanolic extract and solvent fractions (hexane, chloroform, ethyl acetate and aqueous) of stem bark against chloroquine-sensitive infected mice were determined using suppressive and curative procedures.

Background/aim: The objective of this phase I study was to determine the maximum-tolerated dose (MTD) and recommended dose (RD) of combination therapy with weekly nanoparticle albumin-bound paclitaxel (nab-paclitaxel) and cyclophosphamide (CPA) in metastatic breast cancer (MBC) patients.

Patients And Methods: Five patients who had human epidermal growth factor receptor 2 (HER2) negative MBC were recruited in this study. They received nab-paclitaxel at dose levels of 100-150 mg once a week for three weeks, repeated every 4 weeks, and CPA (600 mg/m) administered on day 1.

Background: HER2 (ERBB2) gene amplification and its corresponding overexpression are present in 15-30% of invasive breast cancers. While HER2-targeted agents are effective treatments, resistance remains a major cause of death. The American College of Surgeons Oncology Group Z1041 trial (NCT00513292) was designed to compare the pathologic complete response (pCR) rate of distinct regimens of neoadjuvant chemotherapy and trastuzumab, but ultimately identified no difference.

Article Synopsis
  • This study aimed to evaluate the pathologic complete response (pCR) rate in ER-positive breast cancer patients who had high Ki67 levels after 2-4 weeks of neoadjuvant aromatase inhibitor (AI) therapy, leading to a switch to chemotherapy.
  • A trial including 35 patients found only 5.7% achieved pCR after switching to chemotherapy, which was lower than the expected pCR rate of over 20%.
  • Additionally, the study suggested that patients with a Preoperative Endocrine Prognostic Index (PEPI) score of 0 had a significantly lower risk of relapse (3.7%) compared to those with a PEPI > 0 (14.4%), indicating the potential benefit of

Objective: Syndecan 4 has been implicated as a critical mediator of inflammatory responses because of its functions as a coreceptor and reservoir for growth factors and chemokines. Although syndecan 4 is known to be expressed on B cells, its role in immune responses remains unclear. The purpose of this study was to investigate the contribution of syndecan 4 to the development of immune arthritis in murine models.

Background: Since complications of postmastectomy breast reconstruction may reduce patient satisfaction, we investigated complications of reconstruction with tissue expanders (TEs), particularly surgical site infections requiring TE/permanent implant (PI) removal.

Patients And Methods: A retrospective review was performed of 234 primary breast cancer patients undergoing 239 postmastectomy breast reconstructions with TEs/PIs from 1997 to 2009. Clinicopathological findings and postoperative complications, particularly infections, were analyzed.
