Introduction: Diabetic polyneuropathy (DPN), a common complication of diabetes, can manifest as small, large, or mixed fiber neuropathy (SFN, LFN, and MFN, respectively), depending on the type of fibers involved. Despite evidence indicating small fiber involvement prior to large fiber involvement in type 1 diabetes mellitus (T1DM)-associated DPN, no evidence has been produced to determine the more prevalent subtype. We aim to determine the more prevalent type of nerve fiber damage-SFN, LFN, and MFN-in T1DM-associated DPN, both with and without pain.

Article Synopsis
  • The study aimed to examine structural changes in skin Schwann cells and nerves in individuals with diabetic polyneuropathy, particularly in those with type 1 diabetes, and how these changes relate to neuropathic symptoms.
  • Skin biopsies were analyzed from four groups: individuals with type 1 diabetes without neuropathy, with painless neuropathy, with painful neuropathy, and healthy controls, using immunostaining to visualize Schwann cells and nerve fibers.
  • Results showed significant differences in Schwann cell and nerve fiber density among the groups, particularly between those with diabetic neuropathy and healthy controls, while correlations indicated a link between these structural changes and neuropathic symptoms.

Background And Objectives: Diabetic polyneuropathy (DPN) is a complication of diabetes characterized by pain or lack of peripheral sensation, but the underlying mechanisms are not yet fully understood. Recent evidence showed increased cutaneous macrophage infiltration in patients with type 2 diabetes and painful DPN, and this study aimed to understand whether the same applies to type 1 diabetes.

Methods: The study included 104 participants: 26 healthy controls and 78 participants with type 1 diabetes (participants without DPN [n = 24], participants with painless DPN [n = 29], and participants with painful DPN [n = 25]).

Background: Low-intensity extracorporeal shockwave therapy (LI-ESWT) has been suggested as a treatment for vascular diseases such as ischemic heart disease, diabetic foot ulcers, and erectile dysfunction. Primarily, LI-ESWT is known for its ability to stimulate angiogenesis and activation of stem cells in target tissues. Application of LI-ESWT in chronic progressive renal diseases is a novel area.

Chronic ulcers are most often seen as a complication to venous leg ulcers, diabetic foot ulcers and pressure ulcers. Ulcers often display an underlying medical condition, which makes it mandatory to treat these individuals in a multidisciplinary setting. Modern ulcer therapy has changed over the latest decade, and as described in this review a number of new modalities have been included.

Purpose: Treatment with low-intensity shockwave therapy (LI-ESWT) is associated with angiogenesis and is suggested as a treatment for different types of vascular diseases. It was hypothesized that LI-ESWT improves the renal filtration barrier and halts the progression of GFR decline in diabetic kidney disease (DKD) potentially through VEGF and NO formation. We present the first data on LI-ESWT in human DKD.

Rubeosis faciei diabeticorum, caused by microangiopathy and characterized by a chronic facial erythema, is associated with diabetic neuropathy. In clinical practice, facial erythema of patients with diabetes is evaluated based on subjective observations of visible redness, which often goes unnoticed leading to microangiopathic complications. To address this major shortcoming, we designed a contactless, non-invasive diagnostic point-of-care-device (POCD) consisting of a digital camera and a screen.

Background And Objective: Diabetes mellitus is a common disorder amounting to 400 million patients worldwide. It is often accompanied by a number of complications, including neuropathy, nephropathy, and cardiovascular diseases. For example, peripheral neuropathy is present among 20-30% of diabetics before the diagnosis is substantiated.

Objective: The MHC region harbors the strongest loci for latent autoimmune diabetes in adults (LADA); however, the strength of association is likely attenuated compared with that for childhood-onset type 1 diabetes. In this study, we recapitulate independent effects in the MHC class I region in a population with type 1 diabetes and then determine whether such conditioning in LADA yields potential genetic discriminators between the two subtypes within this region.

Research Design And Methods: Chromosome 6 was imputed using SNP2HLA, with conditional analysis performed in type 1 diabetes case subjects ( = 1,985) and control subjects ( = 2,219).

Aim: (1) To quantify the invisible variations of facial erythema that occur as the blood flows in and out of the face of diabetic patients, during the blood pulse wave using an innovative image processing method, on videos recorded with a conventional digital camera and (2) to determine whether this "unveiled" facial red coloration and its periodic variations present specific characteristics in diabetic patients different from those in control subjects.

Methods: We video recorded the faces of 20 diabetic patients with peripheral neuropathy, retinopathy, and/or nephropathy and 10 nondiabetic control subjects, using a Canon EOS camera, for 240 s. Only one participant presented visible facial erythema.

Background: Low-intensity shockwave therapy (LI-SWT) is suggested as a therapy for promoting tissue regeneration. In pigs, it was recently found that LI-SWT improved renal function after ischaemic injury. Our objectives were to study glomerular filtration rate (GFR) and albuminuria in diabetic nephropathy (DN) after treatment with LI-SWT.

Background: Hospitals increasingly make decisions about early development of and investment in innovative medical technologies (IMTs), but at present often without an early assessment of their potential to ensure selection of the most promising candidates for further development. This paper explores how early assessment is carried out in different health organisations and then discusses relevant learning points for hospitals.

Methods: A qualitative study design with a structured interview guide covering four themes was used.

Objective: Latent autoimmune diabetes in adults (LADA) shares clinical features with both type 1 and type 2 diabetes; however, there is ongoing debate regarding the precise definition of LADA. Understanding its genetic basis is one potential strategy to gain insight into appropriate classification of this diabetes subtype.

Research Design And Methods: We performed the first genome-wide association study of LADA in case subjects of European ancestry versus population control subjects ( = 2,634 vs.

Article Synopsis
  • The study examines how autoimmunity, age of onset, and insulin treatment time affect diabetes subgroups and seeks a more unbiased way to categorize them.
  • A cohort of 4,374 newly diagnosed diabetes patients was grouped based on age at onset, fasting C-peptide levels, and GAD autoantibody status to assess differences in blood sugar control and cardiometabolic risks.
  • Results indicate that fasting C-peptide and GAD autoantibody status are significant indicators of glycaemic control and cardiometabolic risk, whereas age of onset does not show major differences among the groups.

Immune checkpoint inhibitors have improved survival rate in patients with advanced melanoma, but also have the potential to induce several adverse events. We report on a 63-year-old woman who had advanced melanoma and was admitted with diabetic ketoacidosis, which had occurred upon treatment with ipilimumab. On admission, the C-peptide level was low, and the HbA1c concentration was 50 mmol/l indicating a rapid onset of the disease.

Article Synopsis
  • Mitochondrial dysfunction is linked to various health issues like diabetes, neurological disorders, and bone problems, but its specific effects on human bone remodeling are unclear.
  • A study with 45 individuals carrying the m.3243A>G mutation revealed that they had lower bone density and strength compared to healthy controls, with significant differences in bone scans at key sites like the lumbar spine and hip.
  • The presence of diabetes in some participants may have influenced the results, but the findings suggest that mitochondrial dysfunction could lead to accelerated bone aging, resembling age-related bone deterioration.
