The Impact of Continuity of Care on Health Indicators in Patients With Type 2 Diabetes Mellitus in Family Medicine Clinics in Riyadh.

BACKGROUND: Diabetes Mellitus Type 2 (DM2) is highly prevalent in Saudi Arabia, with many experiencing complications due to the disease. Family medicine physicians are usually the primary care providers responsible for the medical management of type 2 diabetes mellitus patients. Microvascular and macrovascular complications can occur if type 2 diabetes mellitus is poorly managed. Effective management of health indicators in patients with DM2 relating to glycated hemoglobin (HbA1c), low density lipoprotein cholesterol, blood pressure, and tobacco use is an essential part of medical care to prev

Fibrinogen and a Triad of Thrombosis, Inflammation, and the Renin-Angiotensin System in Premature Coronary Artery Disease in Women: A New Insight into Sex-Related Differences in the Pathogenesis of the Disease.

Coronary artery disease (CAD) is the leading cause of morbidity and mortality in women worldwide. Its social impact in the case of premature CAD is particularly devastating. Many differences in the presentation of the disease in women as compared to men, including atypical symptoms, microvascular involvement, and differences in pathology of plaque formation or progression, make CAD diagnosis in women a challenge. The contribution of different risk factors, such as smoking, diabetes, hyperlipidemia, or obesity, may vary between women and men. Certain pathological pathways may have different sex

Microvascular changes in the white mater in dementia.

Our studies of the brain microvascular system have focused on some aspects not commonly studied by other research groups because we use some techniques not often used by others. Our observations tend to add new details to the pathological picture rather than contradict the mainstream findings. We use large, thick celloidin sections which provide a three dimensional view of vascular networks, and alkaline phosphatase (AP) staining which allows one to differentiate between afferent and efferent vessels. We found millions of lipid microemboli in the brains of patients after cardiac surgery, and c

Zexieyin formula ameliorates high-fat diet-induced cognitive impairment via pericyte-associated LRP1 modulating CypA/NF-κB/MMP-9 pathway.

BACKGROUND: The global rise in obesity and metabolic syndrome is increasingly recognized as a major risk factor for cognitive decline and neurodegenerative diseases. Chronic high-fat diet (HFD) consumption disrupts blood-brain barrier (BBB) integrity, a pivotal pathological event that facilitates neurotoxic infiltration, neuroinflammation, and neuronal injury. Brain pericytes play a central role in maintaining BBB function and are particularly vulnerable to HFD-induced metabolic stress. Loss or dysfunction of pericytes contributes to BBB breakdown. Low-density lipoprotein receptor-related prot

Correlation of gut microbiota metabolite trimethylamine N-oxide with inflammatory levels and osteoporosis in patients with diabetic nephropathy.

BACKGROUND: Diabetic nephropathy (DN) is one of the most serious microvascular complications of type 2 diabetes mellitus (T2DM), and its incidence increases with the global rise in diabetes prevalence. It is the leading cause of chronic kidney disease and end-stage kidney disease. Patients with DN often experience complex metabolic disorders and chronic inflammatory states, which not only accelerate the decline of renal function but are also closely related to complications such as cardiovascular events and osteoporosis (OP), seriously compromising quality of life.

Case report: A successful second autologous hematopoietic stem cell transplantation in refractory systemic sclerosis, with positive effect on skin involvement, pulmonary function and microcirculation.

BACKGROUND: Systemic sclerosis (SSc) is a complex autoimmune disease characterized by inflammation, vasculopathy and fibrosis of the skin and internal organs. Treatment with autologous hematopoietic cell transplantation (HCT) for progressive SSc has improved overall and event-free survival rates significantly, but unfortunately disease progression after HCT is seen in a subset of patients. Data on the efficacy and safety of second HCT is scarce. CASE: We present a patient with diffuse cutaneous SSc and associated interstitial lung disease (ILD) who successfully underwent a second HCT for prog

UFMTrack, "Недоходный миграционный трекер", позволяющий проанализировать весь многоэтапный каскад экстравазии иммунных клеток через барьер кровеносного мозга в микрофлюидовых устройствах.

Эндотелиальный барьер кровеносного мозга (БДБ) строго контролирует оборот иммунных клеток в центральную нервную систему (КНС). В таких нейро-воспалительных заболеваниях, как множественный склероз, этот жесткий контроль, однако, нарушается, что приводит к инфильтрации иммунных клеток в CNS. Разработка моделей BBB in vitro в сочетании с микрофлюидовыми устройствами способствовала более глубокому пониманию клеточных и молекулярных механизмов посредничества многоэтапной экстравазии Т-клеток по всему BBB. Одним из основных узких мест в этих исследованиях in vitro является отсутствие надежного и авт
