A Clinical Investigation: Study on Psychosocial Characteristics, Social Support and Intervention Strategies of Outpatient Cancer Pain Patients

Background and Objective: The presence of pain in cancer patients is a prevalent concomitant symptom, exerting significant impacts on their physical, psychological, and social functioning. However, the psychological and social aspects are often overlooked. This study aims to explore the factors influencing the provision of psychological and social support for patients experiencing cancer-related pain while proposing intervention measures to enhance treatment compliance, confidence levels, and overall quality of life. Materials and Methods: According to the inclusion and exclusion criteria, a total of 108 patients with moderate to severe advanced cancer pain who had received outpatient analgesia treatment for at least one month were selected as the study subjects. The psychological characteristics and social support of these patients were further examined using the Self-Rating Symptom Scale (SCL-90) and Social Support Rating Scale (SSRS). The influencing factors were compared with the national norms. Results: The total score of SCL-90 was significantly different from that of the domestic norm (P < 0.05), and the total score of social support was significantly different from that of the domestic norm (P < 0.01). In addition to hostile symptoms, Somatic, obsessive, sensitive, depression, anxiety, terror, paranoia, psychosis and other symptoms were correlated with subjective support (P 0.05). Conclusion: Patients with cancer pain are more vulnerable to physical symptoms, psychological distress, lack of social support, and other contributing factors. Implementing standardized treatment protocols can effectively alleviate physical symptoms while also emphasizing the importance of psychosocial interventions to address negative emotions and enhance social support. By bolstering patient confidence through these measures, we can ultimately improve treatment outcomes and enhance patients’ overall quality of life.

Clinical research progress on acupuncture for the treatment of otogenic vertigo

Otogenic vertigo is a common disorder that affects the vestibular system,which often results in considerable discomfort and impaired daily functioning.Traditional Chinese medicine(TCM),including acupuncture and moxibustion,has been historically utilized to manage the symptoms of vertigo.However,the effectiveness and methodology of these treatments have rarely been investigated in the medical literature.This study reviews the existing literature on the point selection,method,and therapeutic effect of acupuncture and moxibustion to provide a reference for the TCM treatment of otogenic vertigo.A literature search was performed using the PubMed search engine.The terms used included otogenic vertigo,acupuncture treatment,and acupuncture point selection.A total of 34 relevant articles were retrieved from PubMed.These suggest that the clinical treatment of otogenic vertigo should consider the functions of zang-fu organs and meridians and select different acupuncture treatment methods according to syndrome differentiation based on the difference between deficiency and excess.Acupuncture and moxibustion therapy should be based on acupoint selection,considering the syndrome differentiation,supplemented with experience.The treatment of otogenic vertigo with acupuncture and moxibustion refers to the selection of appropriate acupuncture methods under the guidance of TCM theory and following the principles of syndrome,disease,and meridian differentiation.Common acupuncture methods include body acupuncture,auricular acupuncture,scalp acupuncture,acupoint injection,electroacupuncture,and moxibustion.There are many acupuncture and moxibustion acupoints selected for the treatment of otogenic vertigo.Individualized treatment according to the patient’s specific condition is effective and safe,which can help to improve the patient’s vertigo symptoms and cerebral blood perfusion.

Phantom Fighters: Coping Mechanisms of Amputee Patients with Phantom Limb Pain: A Longitudinal Study

Phantom Limb Pain (PLP) is a phenomenon commonly observed in orthopedic rehabilitation units that can have detrimental effects on patients’ functioning. Psychological aspects of PLP have been widely investigated showing that some coping mechanisms are advantageous at certain points but not at others. However, the mechanisms related to positive adjustment to PLP during the course of rehabilitation have not been adequately examined. The aim of the study was to investigate the relationship between PLP and coping mechanism at two points during the rehabilitation process. Thirty one orthopedic inpatients, who had undergone lower-limb amputation following diabetic complications, rated their pain levels and mental coping strategies. The Ways of Coping Checklist, Life Orientation Test, and the McGill Pain Questionnaire, 1-15 days post-surgery and six months post-surgery were used for evaluation. Denial was found to be negatively correlated with PLP shortly after amputation. In contrast, optimism was found to be negatively correlated with PLP six months after the surgery. Emotion-focused coping mechanisms were found to be positively correlated with PLP. It is concluded that denial during the early stages of recuperation and optimism at later stages of rehabilitation is associated with reduced PLP. Awareness of these mental processes by both medical staff and family members may enable acceptance of these processes and thus facilitate patients’ rehabilitation.

Kunming mouse strain is less susceptible to elastase-induced abdominal aortic aneurysms

Background:Porcine pancreatic elastase(PPE)is successfully used to induce abdominal aortic aneurysm(AAA)in mice.However,differences between mouse strains in susceptibility to PPE induction have been reported.Kunming mouse is one of the most frequently used strains in China but whether it is suitable for induction of AAA by PPE application remains unclear.Methods:PPE infusion(1.5 units/ml)in temporary controlled aorta was performed to induce AAAs in both C57BL/6J and Kunming mice.Phosphatebuffered saline(PBS)application was used as vehicle control.The aorta diameters of all mice were measured at days 0 and 14 after surgery to evaluate the AAA formation.Results:After 14 days of PPE or PBS infusion,all mice were sacrificed and aorta tissues were collected for histological staining analysis.At the 14th day after infusion,PPE successfully induced aortic dilation in Kunming mice and typical AAA in C57BL/6J mice.The aorta diameter increased by 0.23 mm in Kunming mice after PPE infusion,while it was 0.72 mm in the C57BL/6J strain.PPE induced mild elastin degradation,smooth muscle cell(SMC)depletion and mural leucocyte infiltration in Kunming mice,but in PPE-sensitive C57BL/6J mice,it induced total loss of SMCs,elastin disappearance and diffused infiltrated leucocytes in aortic aneurysmal segments.The effects of PPE in inducing angiogenesis and upregulating matrix metalloproteinase 2 and 9 expression in Kunming mice were also weaker than that in C57BL/6J mice.Conclusion:At the reported dose of PPE,Kunming mouse is not as susceptible to AAA formation as C57BL/6J mice.The failure of PPE to induce AAA formation in Kunming mice may be associated to its inability to boost a strong inflammatory response.
