The association among multiple-site chronic pain, sedentary behavior, and major depressive disorders: a mendelian randomization study.

Objective: Observational studies have reported that major depressive disorder (MDD) is associated with sedentary behavior (SB) and multiple chronic pain (MCP), but their associations remain unclear. Mendelian randomization analysis was used to assess the association.

Methods: Single nucleotide polymorphisms (SNPs) associated with MCP, SB [time spent watching television (Tel), using a computer (Com), or driving (Dri)], and MDD were collected from genome-wide association studies and screened as instrumental variants with a threshold of 1 × 10 -5 .

Differential impacts of initial treatment status on long-term survival in patients with sarcomas treated in a referral center according to histologic type and anatomic site.

Objective: The aim of this work was to estimate the magnitude of the differential impacts of initial treatment status relative to the impact of classic clinicopathologic factors on the long-term overall survival (OS) of sarcoma patients in a referral cancer center.

Methods: From the institutional database, we identified 2185 patients who presented to the institutional multidisciplinary team (MDT) prior to (N = 717, 32.8%) or after (N = 1468, 67.

Evaluating Teaching Effectiveness of Medical Humanities in an Integrated Clerkship Program by a Novel Prospective Propensity Score Matching Framework.

Background: This study aims to rigorously compare the effectiveness of the educational programs of a new integrated clinical clerkship in medicine (3 months) and surgery (3 months) at a cancer center with the conventional subspecialty-based rotations at a tertiary teaching hospital, by this prospective, pre-post comparative method.

Methods: Between 2013-2016, we compared 69 students who had selected the integrated clerkship that emphasized clinical competency and medical humanities training with 138 matched peers who had completed conventional clerkships during the same period. Outcome measures for medical humanities included empathy, patient-centeredness, and other values and skills related to holistic health care professionalism by introducing prospective propensity score matching (PSM).

Does Prosthesis-Based Breast Reconstruction Affect the Clinical Outcome of Postmastectomy Radiotherapy?

Background: In the last 5 decades, there has been significant advancement of breast reconstruction and postmastectomy radiotherapy for breast cancer care. There has been concern that breast reconstruction may adversely affect the efficacy of postmastectomy radiotherapy. This, however, has not been proven by clear clinical evidence.

Investigation of Prognostic Features in Primary Cutaneous and Soft Tissue Angiosarcoma After Surgical Resection: A Retrospective Study.

Primary cutaneous and soft tissue angiosarcoma is a rare but highly aggressive malignancy. To date, surgical resection is the mainstay of treatment, but poor prognosis is expected. To investigate whether there are factors associated with poor prognosis after surgical resection and to develop a treatment guideline for current therapy, we retrospectively collected data on 28 patients who underwent surgery as initial treatment and reviewed patient demographics, tumor characteristics, disease courses, and prognoses from September 1996 to May 2013.

Risk of infection is associated more with drain duration than daily drainage volume in prosthesis-based breast reconstruction: A cohort study.

In prosthesis-based breast reconstruction, drains are used to prevent seroma formation and to reduce the risk of infection. However, prolonged drainage increases the risk of ascending infection. Although the volume often accepted for drain removal is ≤30 mL per day, the optimal timing to remove the drain for best clinical outcome remains controversial.

A clinical clerkship collaborative program in Taiwan: Acquiring core clinical competencies through patient care responsibility.

Background/purpose: Traditionally, clinical clerkship training in Taiwan does not provide medical students with sufficient patient care responsibilities and often results in inadequate clinical skills.

Methods: We implemented a pilot clerkship program at a comprehensive cancer center that emphasizes core clinical competency through direct patient care and dedicated faculty and mentors. Students were an integral part of the patient care team held accountable for providing coordinated and holistic care.

Honokiol, a low molecular weight natural product, prevents inflammatory response and cartilage matrix degradation in human osteoarthritis chondrocytes.

Proinflammatory cytokine interleukin-1β (IL-1β) stimulates several mediators of cartilage degradation and plays an important role in the pathogenesis of osteoarthritis (OA). Honokiol, a low molecular weight natural product isolated from the Magnolia officinalis, has been shown to possess anti-inflammatory effect. Here, we used an in vitro model of cartilage inflammation to investigate the therapeutic potential of honokiol in OA.

EGb761 inhibits inflammatory responses in human chondrocytes and shows chondroprotection in osteoarthritic rat knee.

Osteoarthritis (OA) is a degenerative joint disease involving a combination of cartilage degradation and inflammation. EGb761, a standardized extract of Ginkgo biloba leaves, holds an anti-inflammatory potency. Here, we determined whether EGb761 could inhibit lipopolysaccharide (LPS)- and IL-1β-induced inflammatory responses in human articular chondrocytes and apply the chondroprotection in OA rats.

The prognosis of patients with primary osteosarcoma who have undergone unplanned therapy.

Objective: For diagnosing osteosarcoma correctly, a combination of clinical, radiological and histological examinations is required. Erroneous treatment may cause local contamination and systemic seeding in patients. The purpose of this study was to compare outcomes of planned and unplanned treatment for osteosarcoma.

A novel human stem cell coculture system that maintains the survival and function of culture islet-like cell clusters.

Islet-like cell clusters (ICCs) have been suggested to be a source of insulin-producing tissue for xenotransplantation in type 1 diabetes. We designed an approach to maintain the cultured rat pancreatic ICC survival and function, when cocultured with human umbilical cord mesenchymal stem cells (HUMSCs). HUMSCs in coculture have the ability to maintain ICC survival and function, for which number and insulin secretion of ICCs are increasing and lasting for 3 months, while ICCs gradually crash, which results in cell death after a period of 12 days of culture without HUMSCs.
