RESUMEN

The devastating COVID-19 pandemic has cast a light on the question of why trust in scientists is important. This mixed-method study aimed to explore the study participants' trust in scientists about getting the COVID-19 vaccine. It also aimed to reveal which key sources of information participants followed about the pandemic. Participants' health-related behaviors and justifications for their behaviors as a response to the pandemic were also explored to understand how trust in scientists and sources of information played a role in the fight against COVID-19. The responses of 1233 participants across Turkey were analyzed. The findings indicated that trust in scientists and compliance with the scientists' suggested behaviors among the participants were quite high. It was also revealed that, for both trust and non-trust groups, participants questioned the reliability of information and the sources. Participants justified their behaviors mainly by referring to policies, e.g., masks, distance, and hygiene, developed and implemented with the collaboration of government, scientists, and the World Health Organization. Moreover, trust issues regarding scientists, government authorities, or other citizens were mentioned in participants' justifications. The current study also shed light on the importance of building trust through an open and healthy dialogue among scientists, government authorities, and the public to overcome the COVID-19 pandemic. The study highlighted the need for scientifically informed citizens to deal with the problems, i.e., misinformation and disinformation, in the post-truth era such as not jeopardizing effective solutions to eliminate the pandemic, e.g., taking the vaccine.

RESUMEN

AIMS: Heme oxygenase-1 (HO-1) confers protection to the vasculature and suppresses inflammatory properties of monocytes and macrophages. It is unclear how HO-1 determines the extent of vascular dysfunction in mice and humans. METHODS AND RESULTS: Decreased HO-1 activity and expression was paralleled by increased aortic expression and activity of the nicotinamide dinucleotide phosphate oxidase Nox2 in HO-1 deficient Hmox1⁻/⁻ and Hmox1(⁺/⁻) compared with Hmox1⁺/⁺ mice. When subjected to angiotensin II-infusion, streptozotocin-induced diabetes mellitus and aging, HO-1 deficient mice showed increased vascular dysfunction inversely correlated with HO activity. In a primary prevention population-based cohort, we assessed length polymorphisms of the HMOX1 promoter region and established a bipolar frequency pattern of allele length (long vs. short repeats) in 4937 individuals. Monocytic HMOX1 mRNA expression was positively correlated with flow-mediated dilation and inversely with CD14 mRNA expression indicating pro-inflammatory monocytes in 733 hypertensive individuals of this cohort. Hmox1⁻/⁻ mice showed drastically increased expression of the chemokine receptor CCR2 in monocytes and the aorta. Angiotensin II-infused Hmox1⁻/⁻ mice had amplified endothelial inflammation in vivo, significantly increased aortic infiltration of pro-inflammatory CD11b⁺ Ly6C(hi) monocytes and Ly6G⁺ neutrophils and were marked by Ly6C(hi) monocytosis in the circulation and an increased blood pressure response. Finally, individuals with unfavourable HMOX1 gene promoter length had increased prevalence of arterial hypertension and reduced cumulative survival after a median follow-up of 7.23 years. CONCLUSIONS: Heme oxygenase-1 is a regulator of vascular function in hypertension via determining the phenotype of inflammatory circulating and infiltrating monocytes with possible implications for all-cause mortality.

RESUMEN

BACKGROUND: A variety of anesthetic and analgesic techniques have been used for uterine aspiration, and most clinicians use a paracervical block with or without additional analgesia. We intended to evaluate whether the addition of 10% lidocaine spray to a paracervical block decreases pain during cervical dilation and uterine aspiration. STUDY DESIGN: Seventy-seven patients were divided into two groups: paracervical blocks (PCB) (n = 30) and PCB plus 10% lidocaine spray (n = 47). Anticipated and overall perceived pain scores were measured with a standard Visual Analog Scale (VAS). RESULTS: Anticipated pain VAS scores of two groups were similar, however overall perceived pain VAS scores demonstrated a significant difference. PCB with Lidocaine only group had 6.56 ± 1.43 cm mean VAS score, whereas lidocaine plus lidocaine spray group had 2.35 ± 1.39 cm, the difference being statistically significant (p < .01). CONCLUSION: We found that 10% lidocaine spray safely decreases perceived pain during first-trimester surgical abortion, when used in addition to PCB with lidocaine HCl.
