Low circulating adiponectin and resistin, but not leptin, levels are associated with multiple myeloma risk: a case–control study

Accumulating evidence supports a role for obesity in the etiology of multiple myeloma (MM). The distinct possibility exists that obesity may be linked to MM through altered adipokine secretion and circulating levels, one of which, adiponectin, has a protective role in several malignancies, including leukemia. In this case–control study, we investigated the role of serum adiponectin, resistin, and leptin levels in the etiopathogenesis of MM and we explored their association with several established prognostic factors. Seventy three patients with incident, histologically confirmed MM and 73 controls matched on gender and age were studied between 2001 and 2007, and blood samples were collected. Serum adiponectin, leptin, resistin, as well as MM prognostic parameters were determined. Statistical analysis of the data was performed using univariate and multivariate analyses. Lower serum adiponectin and resistin levels were associated with higher risk of MM by bivariate analysis and after adjusting for age, gender, BMI, and serum levels of leptin (p < 0.0001). Adiponectin may have a protective role in MM, whereas leptin was not associated with risk for MM at a comparable level of significance and resistin levels may be decreased via a compensatory mechanism. Further studies are needed to confirm these associations and to explore the mechanisms underlying adiponectin’s role in MM and plasma cell dyscrasias.     

Taiwan's National Health Insurance at the Emergency Department following the COVID-19 outbreak

Taiwan's National Health Insurance (NHI) is a widely acclaimed universal healthcare system. In the past few years, particularly following the COVID-19 outbreak, challenges related to maintaining the NHI system have surfaced. Since 2020, NHI has faced a series of challenges, including excessive patient visits to the hospital emergency department, a lack of an effective primary care and referral system, and a high turnover rate of healthcare workers. We review major problems related to Taiwan's NHI, emphasizing input from frontline healthcare workers. We provide recommendations for potential policies addressing the concerns around NHI, for example, strengthening the role of primary care services under the NHI administration, reducing the high turnover rate of healthcare workers, and increase the premium and copayments. We hope that this policy analysis may allow policymakers and scholars to understand both the merits and critical problems related to NHI from the clinical perspective.     

CD30-positive lymphoproliferative disorders—An Australian Clinical Practice Statement from the Peter MacCallum Cancer Centre

The CD30-postive lymphoproliferative disorders, including lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma, account for up to 30% of all cutaneous T-cell lymphomas (CTCLs) and are the second most common form of CTCLs after mycosis fungoides. Both conditions differ in their clinical presentations; however, they share the expression of the CD30 antigen as a common immunophenotypic hallmark. There is a wide spectrum of management options depending on factors such as extent of disease, staging and treatment tolerability. This Clinical Practice Statement is reflective of the current clinical practice in Australia.
