Background: Recent evidence suggests that exposures in early life that are known to influence microbiome development may affect the risk of developing inflammatory bowel disease (IBD). Cesarean section has been associated with altered colonization of commensal gut flora and is thought to predispose to immune-mediated diseases later in life.
Aims: To evaluate the risk of IBD, Crohn's Disease (CD), and Ulcerative Colitis (UC) according to mode of delivery (C-section vs vaginal delivery).
Methods: A systematic search was performed in PubMed and Embase. The primary outcome was the risk of IBD in individuals delivered vaginally compared to those born by C-section. Secondary outcomes were UC and CD risk according to mode of delivery and IBD risk in individuals born by emergent compared to elective C-section. Publication bias was evaluated by funnel plots and Egger's test. Study's quality was characterized using the Newcastle-Ottawa Scale.
Results: Ten studies fulfilled the inclusion criteria, of which seven were population-based. No publication bias was detected. Overall, 14.164 IBD patients and 4.206.763 controls were included. Being born by C-section was not associated with increased risk of IBD [OR 1.01, 95% CI (0.81-1.27), p = 0.92], CD [OR 1.15, 95% CI (0.94-1.42), p = 0.18] or UC [OR 0.94, 95% CI (0.61-1.45), p = 0.79]. No differences were found between emergent and elective C-section in IBD [OR 1.05, 95% CI (0.59-1,87), p = 0.87]. Substantial heterogeneity was found in statistical analysis, and further studies are needed.
Conclusion: Overall, the risk of developing IBD was not affected by mode of delivery.

There is a growing body of evidence that the interaction between various microbial organisms and the human host can affect various physical and even mental health conditions. Bidirectional communication occurs between the brain and the gut microbiome, referred to as the brain-gut-microbiome axis. During aging, changes occur to the gut microbiome due to various events and factors such as the mode of delivery at birth, exposure to medications (e.

Background: Data on outcomes associated with various modes of delivery in pregnant patients with heart failure (HF) or pulmonary hypertension (pHTN) are limited.
Objective: We aim to investigate the association between mode of delivery on maternal and fetal outcomes in pregnant patients with HF or pHTN by conducting a multicenter, large scale and nationwide retrospective cohort study.
Methods: This retrospective population-based cohort study used the Nationwide Readmission Database to identify all hospitalized pregnant patients who were primarily admitted for vaginal or cesarean delivery from 2011 to 2019.

This paper presents the development of a transmitter that transforms intermittent glucose sensors (isCGM) into a continuous and real-time glucose monitoring system (c-rtCGM), a key component in automated insulin delivery systems. The transmitter enhances the capabilities of conventional intermittent sensors by leveraging Near Field Communication (NFC) technology to capture raw glucose value and automatically transmit it via Bluetooth Low Energy (BLE-Bluetooth 4.2 Dual-Mode) to a smart device every five minutes.

Background: Maternal cardiovascular disease (CVD) is a leading cause of maternal mortality. Data on anaesthetic management in patients with CVD is limited.
Methods: This ten-year retrospective cohort study of 508 pregnancies in women with CVD, stratified by modified World Health Organization (mWHO) risk category, compared lowrisk (mWHO I-II) (n = 323) and high-risk (mWHO II to III-IV) (n = 185) groups to a control obstetric population (n = 55,153).

Although cold atmospheric plasma is a promising therapeutic technique for tumor immunotherapy via reactive oxygen and nitrogen species (RONS), the challenges associated with the generation and delivery of these RONS hamper clinical adoption. Herein, a dual-mode hybrid discharge plasma-activated sodium alginate hydrosols (PAH) is proposed to enhance the antitumor immune response. Gaseous highly reactive RONS are generated by dual-mode hybrid plasma produced by mixed O and NO modes, which are converted into aqueous RONS in PAH via gas-liquid reactions between plasma and hydrosols.
