Background: Data about the risk of recurrence of vacuum extraction (VE) in multiple consecutive deliveries are scarce. We aimed to evaluate the pattern and individual cumulative risk of recurrence of VE in consecutive term deliveries.

Study Design: A retrospective cohort study based on a validated electronic database at a single center between 2005 and 2019. For the purpose of the study, we focused on consecutive term deliveries of all primiparas (P1) that had a record of at least one additional delivery during the study period. We identified P1 VE deliveries (reference group) and calculated the individual cumulative risk of repeated VE for three consecutive deliveries. Multivariate analysis was conducted adjusting for potential confounders.

Results: We identified 35 113 primiparas that met inclusion criteria. The overall VE rate for P1 was 17.9% (6969 parturient). The cumulative rates of repeated VEs at the 2nd, 3rd, and 4th deliveries were 8.6%, 26.8%, and 25.0%, respectively. The risk of recurrent VE for each of the consecutive deliveries was confirmed after adjustment for confounders (aOR [95% CI]: 5.8 [4.76-7.04], 34.2 [18.59-62.81], and 113.9 [9.77-1328.69] for the 2nd, 3rd, and 4th consecutive deliveries, respectively).

Conclusion: Women with VE at the first and second deliveries have a substantially increased risk of VE in their following deliveries; this finding may influence woman's preference when choosing future mode of delivery.

The utilization of dissolvable microneedles (MNs) is a promising and cutting-edge approach to drug delivery for the treatment of psoriasis, an autoimmune skin disorder characterized by the appearance of red, scaly patches on the skin. This study presents the development of a dissolving MN patch made of polyvinylpyrrolidone for the purpose of delivering Clobetasol 17-Propionate through the skin. The MN patches were evaluated for their physical characteristics, including morphology, solubility, strength, and ability to penetrate the skin.

Background: The COVID-19 pandemic has had a negative impact on the population's mental health, particularly for individuals with health anxiety (HA) and obsessive compulsive disorder (OCD). This is in conjunction with a significant change in accessibility of face-to-face psychological services which have had to rapidly adapt to the remote delivery of therapy.

Aims: Using a single-arm open trial design, the study aimed to evaluate the effectiveness of evidence-based CBT interventions for HA and OCD delivered via a blend of online therapist consultations interspersed with self-study reading materials.

Traditional drug delivery strategies often have side effects due to uneven drug distribution leading to the subtherapeutic impacts. Ligand-modified nanoparticles offer a revolutionary approach to precise drug delivery. These modified nanoparticles can potentially target macrophages, which is crucial for defense and disease progression efficiently.

Background: Normal sleep architecture is important for brain development, and we previously demonstrated that a single exposure to isoflurane during the neonatal period did not induce changes in the sleep architecture and only minimally altered neuronal beta oscillations in adolescent rats. Here, we hypothesized that a more clinically relevant scenario of repeated shorter exposures to isoflurane during brain development may have more profound effects on sleep and wake behavior and associated delta and theta oscillations, respectively.

Methods: Male and female rat pups were exposed to sham anesthesia (30% oxygen) or repeated isoflurane delivery for 2 hours each on 3 consecutive days (total exposure of 6 hours).
