Article Abstract
Background: Three instrument arms are used in the current form of reduced-port robotic gastrectomy (RPRG) for gastric cancer. Based on our experience in performing reduced-port laparoscopic gastrectomy (RPLG), we have recently performed RPRG using two instrument arms.
Methods: From February 2018 to January 2019, we performed RPRG using two instrument arms for gastric cancer. One endoscope arm and two instrument arms of da Vinci® Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) were applied in robotic lymphadenectomy. A commercial multi-lumen single-port trocar was used for the endoscopy port.
Results: A total of 18 patients underwent the planned robotic surgery using two instrument arms. Median operation time was 288.5 (213.0-446.0) minutes, and median hospital stay was 11.0 (7-18) days. Four patients experienced postoperative complications: one Clavien-Dindo grade IIIa, and the other three grade II. No mortality was reported. The number of retrieved lymph nodes did not differ between patients who underwent RPRG and RPLG (p = 0.412).
Conclusion: Gastric cancer surgery using two instrument arms of a robotic surgical system can be performed by surgeons with expertise of RPLG. If this technique is successfully introduced in robotic surgery, it is expected to shorten the path to pure single-port robotic gastrectomy.

The integration of robotic platforms in breast oncology has witnessed substantial expansion, fueled by their inherent advantages in minimally invasive access and enhanced intraoperative maneuverability. Most of the robotic-assisted breast surgery has been performed using multi-arm robots. However, the implementation of single-port robotic (SPr) systems in mammary interventions continues to undergo rigorous clinical evaluation, particularly regarding long-term oncological safety and cost-effectiveness metrics.

Background: Community Access to Palliative Care via Interprofessional Teams Improvement (CAPACITI) is a virtual educational program designed to support primary care providers in delivering a palliative approach to care. This study evaluated whether expert-facilitated sessions result in greater self-rated competency than a self-directed format across three CAPACITI modules: Identification and Assessment, Communication, and Ongoing Management.
Methods: We conducted a randomized controlled trial where 566 interprofessional primary care team members were randomized to facilitated or self-directed delivery of the CAPACITI program.

Background: Nutrition is essential during pregnancy, affecting maternal and child health worldwide. Mid Upper Arm Circumference (MUAC) is a low-cost measure of nutritional status. This study looks at the role of MUAC in assessing pregnant women's nutrition and how it relates to demo-graphics and dietary factors.

Purpose: Understanding the mechanisms through which poverty influences perinatal depression can provide insight into how to develop interventions to improve maternal mental health. To address this question, we aim to estimate indirect effects of important mediators on the causal relationship between food insecurity and symptoms of postnatal depression.
Methods: We used data from the control arm of the Africa Focus on Intervention Research for Mental health - South Africa (AFFIRM-SA) trial that included pregnant women with perinatal depression.

Introduction: Biofeedback is a non-pharmacological treatment option valued for its minimal risk of adverse events and offers a safe alternative for individuals seeking preventive care for migraine. Despite level A evidence for migraine prevention, biofeedback treatment is still unavailable to most patients. We developed a novel medical device (Cerebri) for multimodal biofeedback treatment that omits the need for healthcare personnel involvement.
