To examine insulin pump and continuous glucose monitoring (CGM) use with pregnancy-related outcomes in women with type 1 diabetes.
We abstracted medical records of 646 pregnancies in 478 women with type 1 diabetes, with information on insulin pump versus multiple daily injection (MDI) use and CGM use. We analyzed the associations of pump vs. MDI use, CGM use vs. non-use and pregnancy-related outcomes using mixed effect models.
Pump use was associated with lower HbA1c levels in the first [β (95% CI)=-0.33 (-0.51, -0.15) %] and second trimester [β (95% CI)=-0.13 (-0.24, -0.02) %], increased birth weight [β (95% CI)=0.14 (0.02, 0.26) kg], birth weight percentile [β (95% CI)=4.87 (0.49, 9.26) %], higher odds of large for gestational age [OR (95% CI)=1.65 (1.06, 2.58)] and macrosomia [OR (95% CI)=1.81 (1.03, 3.18)]. CGM use was associated with lower first [β (95% CI)=-0.38 (-0.64, -0.13) %] and third trimester [β (95% CI)=-0.17 (-0.33, -0.00) %] HbA1c levels.
Women with type 1 diabetes who used pump or CGM had better glycemic control during pregnancy; however, pump use was associated with higher birth weight measures.

Osteoporosis is caused by an imbalance between osteoblastic bone formation and osteoclastic bone resorption. Recently, increasing evidence has suggested that long non-coding RNAs (lncRNAs) participate in the occurrence and development of osteoporosis. Herein, we explored the role of lncRNA KCNQ1OT1 in osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). QPCR results indicated that KCNQ1OT1 and RICTOR were down-regulated, while miR-205-5p was up-regulated in the osteoporotic patients, as compared with non-osteoporotic controls. During the osteogenic differentiation of BMSCs, the expression of KCNQ1OT1 and RICTOR was upregulated, whereas miR-205-5p was downregulated. The interaction among KCNQ1OT1, miR-205-5p and RICTOR was validated by dual luciferase reporter system. KCNQ1OT1 promoted RICTOR expression via inhibiting miR-205-5p, therefore promoting osteogenesis as demonstrated by ALP assay, alizarin red staining and the increased expression of osteogenic markers (OPN, RUNX2 and OCN). Furthermore, KCNQ1OT1 overexpression or miR-205-5p inhibition could promote ALP activity and mineralization of BMSCs, while overexpressed miR-205-5p could reverse the effects of overexpressed KCNQ1OT1, and knockdown of RICTOR could reverse the effects of miR-205-5p inhibition. In conclusion, our study illustrated that KCNQ1OT1 might inhibit miR-205-5p in BMSCs, thus upregulating the expression of RICTOR and promoting osteogenic differentiation.Glucocorticoid (GC)-induced osteoporosis (GIOP) is the most common type of secondary osteoporosis. Osteoblast apoptosis induced by GCs is now considered as a crucial factor for GIOP. Many clinical, in vivo, and in vitro studies have shown that metformin has a beneficial effect on bone metabolism and bone formation. To investigate whether metformin could be used to treat GIOP, we explored the influence of metformin on dexamethasone (Dex)-induced apoptosis of osteoblasts and its underlying mechanisms. In this study, the CCK8 assay was used to determine the optimal metformin concentration and processing time. The expression levels of target proteins were examined by Western blot and immunofluorescence; the expression levels of target genes were tested by quantitative PCR. Apoptotic cells were detected using flow cytometry. Characteristics of autophagy were observed by transmission electron microscopy. An autophagy inhibitor was administered to investigate whether autophagy decreases apoptosis. Sh-AMPK transfection and an mTOR activator were used to investigate the role of AMPK/mTOR signaling in metformin-induced autophagy. The results showed that metformin alleviated Dex-induced apoptosis of osteoblasts accompanied by increased autophagy. Treatment with the autophagy inhibitor 3-methyladenine (3-MA) attenuated the effect of metformin on apoptosis, autophagy, and the AMPK/mTOR/p70S6K signaling pathway. The anti-apoptotic effect of metformin on osteoblasts is associated with the promotion of autophagy. Furthermore, sh-AMPK transfection and the mTOR activator MHY1485 impaired metformin-mediated inhibition of osteoblast apoptosis and promotion of autophagy. The AMPK/mTOR/p70S6K signaling pathway plays a role in metformin-mediated apoptosis suppression and autophagy promotion. In conclusion, metformin can alleviate Dex-induced osteoblast apoptosis by inducing autophagy via the AMPK/mTOR/p70S6K pathway. This study highlights the potential value of metformin in the treatment of GIOP.The N6-methyladenosine (m6A) RNA modification is important in post-transcriptional regulation of RNA and are regulated reversibly by methyltransferases (writers), demethylases (erasers) and m6A recognition proteins (readers). Changes in the structure and function of key RNAs contribute to the development of diseases, particularly tumors. Many abnormal expressions of molecules related to m6A RNA methylation modification are discovered in gastric cancer (GC), which changes the methylation level and stability of target genes after transcription, and then regulates related metabolic pathways, affecting the occurrence and progression of GC. Therefore, an in-depth study of m6A RNA modification in GC is conducive to the development of new tumor therapies and the achieve of individualized treatment. At present, both basic and clinical studies indicate that m6A plays a complex and contentious role in GC. In this paper, we not only review the roles and mechanisms of m6A modified related proteins, but also discuss the value of m6A modulators in the clinical applications and current challenges of GC, aiming to provide research clues for the early diagnosis and explore the feasibility of m6A related proteins as specific targets for GC immunotherapy.
Gabapentinoids (GABAs) and serotonergic drugs (selective serotonin reuptake inhibitors [SSRIs]/serotonin and norepinephrine reuptake inhibitors [SNRIs]) are increasingly being prescribed as potential substitutes to opioids and benzodiazepines (benzos), respectively, to treat co-occurring pain and anxiety disorders. The toxicities of these drug classes and their combinations are not well understood.
We conducted a matched case-control study using 2013-2016 Medicare files linked to the National Death Index. Cases were enrollees who died from drug overdose. Controls were enrollees who died from other causes. Cases and controls were matched on patient characteristics and prior chronic conditions. Possession of any opioids, GABAs, benzos, and SSRIs/SNRIs in the month prior to death was defined as drug use. Combination drug use was defined as possessing at least 2 types of these prescriptions for an overlapping period of at least 7 days in the month prior to death.
Among 4323 matches, benzo possession was asswere not associated with decreased risk compared with opioids, raising concerns for GABAs' perceived relative safety.Differentiating patients with type 1 and type 2 myocardial infarction (MI) and acute non-ischemic myocardial injury continues to be a problem for many clinicians. Type 1 MI is the most easily defined. It involves the rise and fall of blood troponin measurements (only falling values if the patient arrives late) with an appropriate clinical observation consistent with myocardial ischemia. Diagnosis and therapy of type 1 MI are well understood and usually present no problem to the physician. The clinical scenarios leading to type 2 MI and non-ischemic myocardial injury are, however, often fraught with greater degrees of uncertainty. In addition, therapy for these latter 2 entities is poorly defined. This review will present 3 patient scenarios that should help clinicians understand the difference between these 3 entities as well as possible therapeutic interventions.Exposure to ambient volatile organic compounds (VOCs) in urban areas is of interest because of their potential adverse effects to public health. A study was carried out to elucidate ambient sources of VOCs in the Capital Region of New York State for the period 2015-2019. A combined dataset of VOCs and PM2.5 species was used in positive matrix factorization (PMF) model to better interpret the complex nature of different sources. Ten sources were revealed, where background source (3.8 μg/m3, 30%) was the largest contributor to VOCs, followed by petroleum-related emissions (2.9 μg/m3, 22%) and pyrolyzed oxygen (OP)-Elemental Carbon (EC2)-aldehydes-rich (2.7 μg/m3, 21%). Other notable VOC sources included methyl ethyl ketone (MEK)-rich, vehicular traffic, and biomass burning. Both OP-EC2-aldehydes-rich and petroleum-related emissions showed notable contribution to ozone (O3) and secondary organic aerosol (SOA) formation, respectively. Observed mean carcinogenic risk values of benzene and formaldehyde and 95th percentiles risk values of 1,3-butadiene and acetaldehyde were above the USEPA acceptable level of 1x10-6 but below a tolerable risk of 1x10-4. Estimated carcinogenic risk values of OP-EC2-aldehydes-rich, vehicular traffic, background and petroleum-related emissions were above the USEPA acceptable cancer risk and posed greater risk to public health (more than 80% of total carcinogenic risk) compared to other sources. Due to lack of some VOC species data (e.g., alkanes, alkenes, terpenes, alcohols), other urban VOC sources e.g., fugitive emissions, fuel evaporation, unburned fuel were not identified. More work is needed to better understand the contribution of VOC sources to O3 and SOA formation in Albany and surrounding region. Findings can support policy makers in developing appropriate air quality management initiatives for the Capital Region in New York State.The issues of global plastic waste generation and demand for hydrogen energy can be simultaneously resolved by gasification process. In this regard, feasibility and efficiency of steam and air co-gasification of coal by incorporating five different and prevalent types of plastic waste were investigated in this modeling study. All steam and air coal/plastic waste co-gasification types were multi-objective optimized utilizing a response surface methodology. The best co-gasification types were selected using VIekriterijumsko KOmpromisno Rangiranje (VIKOR) analysis. Overall, the results showed that incorporating plastic waste into coal gasification improved hydrogen concentration in the syngas and increased normalized carbon dioxide production due to the high carbon content of plastic waste and activation of water-gas and CO shift reactions. VIKOR analysis revealed that steam coal/low density polyethylene was the best optimized co-gasification type with hydrogen concentration of 62.8 mol %, normalized carbon dioxide production of 2.
