AI Article Synopsis
- The study investigates the incidence and risk factors of posttransplant diabetes mellitus (PTDM) in Mexican kidney transplant recipients, finding a 10.1% occurrence among the 522 participants.
- Key independent risk factors for developing PTDM included a cumulative prednisone dosage greater than 13 grams and experiencing one or more acute rejection episodes post-transplantation.
- The findings suggest a need for further research into how inflammatory mechanisms related to acute rejection may contribute to the development of PTDM.
Article Abstract
Background: Many risk factors are associated with the development of posttransplant diabetes mellitus (PTDM), which has adverse effects on graft and patient survival. We report the incidence and risk factors associated with the development of PTDM in Mexican kidney recipients.
Methods: In a retrospective cohort study, we included kidney transplants performed between January 1, 1994 and December 31, 2000; all patients were followed up for at least 1 year posttransplantation. PTDM was defined as fasting blood glucose >126 mg/dL on at least two occasions. Statistical analysis included estimation of crude relative risk (RR) with 95% confidence intervals (CI). Adjusted RR and 95% CI by logistic regression were used.
Results: We studied 522 kidney recipients. Fifty three (10.1%) cases of PTDM were identified in this cohort. Cumulative dosage of prednisone (PDN) >13 g (RR 7.6, 95% CI 1.5-16.3 p <0.0001) and the presence of >or=1 acute rejection episodes (RR 3.7, 95% CI 1.2-11.6 p <0.001 were independent risk factors associated with the development of PTDM. Obesity (RR 2.6, 95% CI 0.8-8.7, p = 0.083) and age range of 40-49 years (RR 2.0; 95% CI 0.6-7.2, p = 0.093) were identified as marginal risk factors.
Conclusions: The incidence of PTDM in kidney recipients was 10.1% in our population. Cumulative PDN dosage and presence of >or=1 acute rejection episodes were independent risk factors for the development of PTDM. These results are consistent with prior studies of the diabetogenic effect of the PDN. The relationship between acute rejection and PTDM deserves further investigation in order to learn more about the role that inflammatory mechanisms may play in this association.

Clinical Relevance: There are many recognised risk factors for retinal vein occlusions. It is plausible that musicians who play wind instruments or use their voice as their primary instrument may be at increased risk of branch retinal vein occlusions through repeated Valsalva manoeuvre.
Background: Repeated valsalva manoeuvres are commonly performed by musicians using high resistance wind instruments.
Assessing bioaccumulation with biomagnification factors from dietary bioaccumulation tests.

Despite the fact that the UN Stockholm Convention on persistent organic pollutants specifically acknowledges that Arctic ecosystems and Indigenous communities are particularly at risk due to biomagnification of contaminants in traditional foods, the bioconcentration factor (BCF) of substances in fish remains the preferred metric for identifying the biomagnification potential of organic substances. The BCF measures uptake of substances from water in water-breathing organisms, but not biomagnification of contaminants from food sources. The purpose of this study is to investigate how the biomagnification factor (BMF) can be used in bioaccumulation assessments.
