The induction or exacerbation of autoimmune diseases is a potential adverse effect of immunostimulating drugs. Vaccines have been suspected of such actions. Epidemiological studies, however, have so far failed to demonstrate any causal relationship between vaccination and autoimmune diseases, including insulin-dependent diabetes mellitus (IDDM). In this study, autoimmune diabetes-prone non-obese diabetic (NOD) mice were treated with two multivalent diphtheria, tetanus, pertussis, poliomyelitis and haemophilus vaccines (diphtheria, tetanus, acellular pertussis, inactivated polio (DTaP-IVP) or DTaP-IVP/Haemophilus influenza type b (Hib)) intraperitoneally at each of 10, 12 and 14 weeks of age. Although non-statistically significant, the incidence of autoimmune diabetes was slightly reduced by the DTaP-IVP vaccine. Blood glucose levels were actually significantly reduced in the mice treated with the DTaP-IVP vaccine relative to the untreated control mice. A slight decrease in blood glucose levels amongst the mice given the DTaP-IVP/Hib vaccine was also noted. Therefore this study does not support previous claims that children's vaccination might be associated with acceleration or exacerbation of IDDM.

Universal salt iodisation (USI) plays an essential role in the provision of iodine (I) to populations worldwide. Countries adopting USI programmes, adhering to strict criteria laid down by expert organisations such as the Iodine Global Network, are estimated to have reduced the prevalence of I deficiency by 75% (protecting 720 million individuals worldwide). Despite this success, doubts have been raised as to the desirability of continuing such programmes because of (a) the need to reduce salt intake for cardiovascular prevention and (b) the induction of thyroid autoimmunity.

This review synthesizes the findings from 252 studies to explore the relationship between the oral pathogens associated with periodontitis, dental caries, and systemic diseases. Individuals with oral diseases, such as periodontitis, are between 1.7 and 7.

Type 1 diabetes (T1D) is caused by the immune-mediated loss of pancreatic β-cells. Hypoxia-inducible factor 1α (HIF-1α) is a transcription factor which is crucial for cellular responses to low oxygen. Here, we investigate the role of β-cell HIF-1α in β-cell death and diabetes after exposure to multiple low-dose streptozotocin (MLDS).

Insulin resistance (IR) is the most important factor involved in the pathogenesis of type 2 diabetes but may also develop in type 1 diabetes (T1DM). Developing IR in patients with T1DM may generate a burden in achieving glycemic targets and may deteriorate the overall prognosis. This review aims to describe the pathogenesis of IR in T1DM, summarize the common associations of IR with other conditions in patients with T1DM, describe the consequences of developing IR in these patients, and present the interventions that target IR in people with T1DM.

Soft tissue reconstruction in the lower limbs presents a significant challenge, particularly when addressing defects in the distal third of the leg, ankle, and foot. The reverse sural flap reliant on the perforating branches of the peroneal artery has emerged as a versatile option, offering a solution for patients for whom microsurgical techniques are not feasible. Despite its advantages, the procedure carries inherent risks, especially in populations with underlying conditions, such as venous insufficiency, cardiovascular disease, and diabetes, as well as in elderly patients, where the likelihood of flap necrosis is elevated.
