The Impact of Motivational Interviewing and Social Media-Based Patient Monitoring on Metabolic Control and Self-Efficacy in Adolescents With Type 1 Diabetes: A Randomized Controlled Trial

This clinical study aims to determine the effects of motivational interviewing and social media-based patient monitoring on metabolic control and self-efficacy in adolescents with Type 1 diabetes. Additionally, the study will assess the adolescents' attitudes toward their disease, quality of life, and perceived levels of social support. The primary research questions are as follows:
For adolescents with Type 1 diabetes who receive motivational interviewing and social media-based monitoring:
How do their attitudes toward their disease compare to those in the control group? How do their perceived levels of social support compare to those in the control group? How do their self-efficacy levels compare to those in the control group? How does their quality of life compare to that of the control group? How do their HbA1c levels compare to those in the control group?

Knockdown of NEAT1 prevents post-stroke lipid droplet agglomeration in microglia by regulating autophagy

Article

作者: Huber, Sabine E ; Bähr, Mathias ; Graf, Irina ; Xin, Wenqiang ; Huttner, Hagen B ; Gerner, Stefan T ; Kilic, Ertugrul ; Pan, Yongli ; Wei, Wei ; Popa-Wagner, Aurel ; Doeppner, Thorsten R ; Hermann, Dirk M ; Tatenhorst, Lars

AbstractBackgroundLipid droplets (LD), lipid-storing organelles containing neutral lipids like glycerolipids and cholesterol, are increasingly accepted as hallmarks of inflammation. The nuclear paraspeckle assembly transcript 1 (NEAT1), a long non-coding RNA with over 200 nucleotides, exerts an indispensable impact on regulating both LD agglomeration and autophagy in multiple neurological disorders. However, knowledge as to how NEAT1 modulates the formation of LD and associated signaling pathways is limited.MethodsIn this study, primary microglia were isolated from newborn mice and exposed to oxygen-glucose-deprivation/reoxygenation (OGD/R). To further explore NEAT1-dependent mechanisms, an antisense oligonucleotide (ASO) was adopted to silence NEAT1 under in vitro conditions. Studying NEAT1-dependent interactions with regard to autophagy and LD agglomeration under hypoxic conditions, the inhibitor and activator of autophagy 3-methyladenine (3-MA) and rapamycin (RAPA) were used, respectively. In a preclinical stroke model, mice received intraventricular injections of ASO NEAT1 or control vectors in order to yield NEAT1 knockdown. Analysis of readout parameters included qRT-PCR, immunofluorescence, western blot assays, and behavioral tests.ResultsMicroglia exposed to OGD/R displayed a temporal pattern of NEAT1 expression, peaking at four hours of hypoxia followed by six hours of reoxygenation. After effectively silencing NEAT1, LD formation and autophagy-related proteins were significantly repressed in hypoxic microglia. Stimulating autophagy in ASO NEAT1 microglia under OGD/R conditions by means of RAPA reversed the downregulation of LD agglomeration and perilipin 2 (PLIN2) expression. On the contrary, application of 3-MA promoted repression of both LD agglomeration and expression of the LD-associated protein PLIN2. Under in vivo conditions, NEAT1 was significantly increased in mice at 24 h post-stroke. Knockdown of NEAT1 significantly alleviated LD agglomeration and inhibited autophagy, resulting in improved cerebral perfusion, reduced brain injury and increased neurological recovery.ConclusionNEAT1 is a key player of LD agglomeration and autophagy stimulation, and NEAT1 knockdown provides a promising therapeutic value against stroke.Graphical abstract

BACKGROUNDBasal cell carcinoma (BCC) is the most frequent form of skin cancer. The etiology of recurrent BCC is multifactorial, and the recurrence rate is variable.OBJECTIVEThe aim of the study was to identify the risk factors of local recurrence after surgical excision in primary BCC.MATERIALS AND METHODSIn our study, 934 patients histopathological diagnosed with BCCs between January 2017 and June 2022 were evaluated retrospectively. Among these, patients who were regularly followed up for at least three years were included in the study. Patients who underwent non-excision treatment were excluded. All the patients who had pathologically confirmed, surgically excised BCCs with safety margins and those with a clinicopathological diagnosis of recurrent BCCs. Demographic and clinical features of 78 patients with non-recurrent primary BCC and 55 patients with local recurrent BCC were compared.RESULTSThe mean age was 69.7±11.7 years. The gender distribution was M/F:1.3. The time from diagnosis to total surgical excision was 2.3±1.4 months, and the time of recurrence was 27.5±23.3 months. The age of the patients, the time from diagnosis to total excision, the lesion size > 2 cm, and the presence of risk factors (such as radiotherapy, malignancy, and immunosuppression) were higher in the recurrent group than in the non-recurrent group (p < 0.05). Location (high/medium/low-risk area) and the presence of multiple lesions did not differ significantly between the recurrent and non-recurrent groups.CONCLUSIONIn patients with BCC, recurrence is often detected in the first three years after diagnosis. Our study determined age, lesion size, accompanying risk factors, and the length of time until total excision as risk factors for recurrence in BCC patients. The histological subtype and lesion localization did not differ between the group with and without recurrence.

Heterozygous Pyrin (MEFV) E148Q allele carriers indicate a reduced glaucoma risk for Turkish population: a prospective clinical analysis

Article

PURPOSEThe MEFV gene encodes pyrin, a protein linked to increased severity of symptoms in Familial Mediterranean Fever (FMF). We consider that inflammation due to MEFV variants would increase eye inflammation and damage aqueous humor regulation. The present study is the first analysis investigating a MEFV (E148Q) variant as a marker protecting from glaucoma.METHODSIn this prospective clinical analyze, we performed detailed gene sequencing focusing on 22 specific regions of the pyrin (MEFV) gene. The study involved two distinct groups: individuals diagnosed with glaucoma (n = 200) and control subjects without glaucoma (n = 100). Both groups were carefully selected to exclude individuals with symptoms or a previous diagnosis of Familial Mediterranean Fever (FMF). The diagnosis of glaucoma for each participant was rigorously established through comprehensive direct ophthalmic examinations.RESULTSA significant odds ratio for protection against glaucoma was found in carriers of the subclinical E148Q allele (OR:2.22; 95%CI: 1.098-4.485). No significant differences were found for other variants. One mutant E148Q-allele could decrease the probability of glaucoma development by approximately 68,9%. We observed no differences in the genotype frequency between glaucoma and healthy for the other MEFV gene variants.CONCLUSIONThe pyrin variant of the MEFV gene resulting in a subclinical phenotype appears to reduce the incidence of glaucoma, and heterozygous pyrin (MEFV) E148Q allele carriers confer protection against glaucoma. It is important to consider the limitations arising from the relatively small number of studies conducted on this topic.
