Diabetes and Chronic Pancreatitis: Considerations in the Holistic Management of an Often Neglected Disease.

Diabetes secondary to chronic pancreatitis (CP) or type 3cDM refers to a brittle form of diabetes and is often characterised by hypoglycaemic episodes, erratic glycaemic control, and impaired quality of life. It differs from other forms of diabetes and is typically characterised by concurrent pancreatic endocrine and exocrine insufficiency which can present as malabsorption and nutritional deficiencies. In this review, we discuss the pathogenesis, epidemiology, and the practicalities of diagnosis, screening, and management of this condition.

Changing the system by changing the workforce: employing consumers to increase access, cultural diversity, and engagement.

Services to families have traditionally been delivered in a medical model. This presents challenges including workforce shortages, lack of cultural diversity, lack of training in strength-based work, and difficulty in successfully engaging and retaining families in the therapy process. The system of care (SOC) effort has worked to establish formal roles for caregivers in SOC to improve services. This paper provides an example of one community's efforts to change the SOC by expanding the roles available to caregivers in creating systems change. It describes the model developed by Communities of Care (CoC), a SOC in Central Massachusetts, and its evolution over a 10 year period. First person accounts by system partners, caregivers hired into professional roles as well as a family receiving services, demonstrate how hiring caregivers at all levels can change systems and change lives, not only for those being served but for the caregiver/professionals doing the work. It also demonstrates, however, that change at the system level is incremental, takes time, and can be fleeting unless an ongoing effort is made to support and sustain those changes.

Maternal folate and other vitamin supplementation during pregnancy and risk of acute lymphoblastic leukemia in the offspring.

The Australian Study of Causes of Acute Lymphoblastic Leukemia in Children (Aus-ALL) was designed to test the hypothesis, raised by a previous Western Australian study, that maternal folic acid supplementation during pregnancy might reduce the risk of childhood acute lymphoblastic leukemia (ALL). Aus-ALL was a national, population-based, multicenter case-control study that prospectively recruited 416 cases and 1,361 controls between 2003 and 2007. Detailed information was collected about maternal use of folic acid and other vitamin supplements before and during the index pregnancy. Data were analyzed using logistic regression, adjusting for matching factors and potential confounders. A meta-analysis with the results of previous studies of folic acid supplementation was also conducted. We found weak evidence of a protective effect of maternal folate supplementation before pregnancy against risk of childhood ALL, but no evidence for a protective effect of its use during pregnancy. A meta-analysis including this and 2 other studies, but not the study that raised the hypothesis, also found little evidence that folate supplementation during pregnancy protects against ALL: the summary odds ratios (ORs) for folate supplementation were 1.06 [95% confidence interval (CI): 0.77-1.48] with reference to no folate supplementation and 1.02 (95% CI: 0.86-1.20) with reference to no vitamin supplementation. For vitamin supplementation in general, the summary OR from a meta-analysis of 5 studies-including Aus-ALL-was 0.83 (95% CI: 0.73-0.94). Vitamin supplementation in pregnancy may protect against childhood ALL, but this effect is unlikely to be large or, if real, specifically due to folate.

Rehabilitative ultrasound imaging of pelvic floor muscle function.

This commentary provides an overview of the current concepts and evidence related to rehabilitative ultrasound imaging of pelvic floor (levator ani) function. As this is an emerging topic, the goal is to provide a basic understanding of ultrasound imaging applications related to levator ani function: the available quantitative and qualitative information, the limitations, as well as how ultrasound imaging can be incorporated as a form of biofeedback during rehabilitation. Furthermore, as the ability to compile and compare existing evidence depends on the degree of similarity in methodology by investigators, this commentary highlights points of consideration and provides guidelines, as well as an agenda, for future investigation.

Is there a folate-related gene-environment interaction in the etiology of childhood acute lymphoblastic leukemia?

Acute lymphoblastic leukaemia (ALL) is the commonest childhood cancer in developed countries. Little is known about its causes, although its early age at diagnosis has focused interest on maternal and perinatal factors. We have previously observed a protective effect of maternal folate supplementation during pregnancy against ALL, and a number of studies have reported protective effects of some common polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) gene. One study has suggested that the effect of MTHFR polymorphisms on risk of ALL may depend on folate status. This study aimed to look for evidence of an interaction between maternal folate supplementation and child's genotype among the cases from our previous study. Bone marrow specimens from 82 of 83 case children were available. DNA was extracted and genotyped for MTHFR C677T and A1298C using standard techniques. We used a case-only analysis to estimate the case-only odds ratio (COR) for MTHFR genotype and folate supplementation in association with ALL. None of the CORs indicated a significant departure from a multiplicative model. Adjustment for sex, age or genotype at the other locus had little effect on the results. Other studies of this gene and environment interaction in ALL and other cancers have produced contradictory results, perhaps because of varying definitions of folate exposure. Further research into the interaction of folate intake and genotype in causing ALL and other cancers is needed. We are specifically studying it in an Australian national case-control study of genetic and environmental causes of ALL.
