Urban landscape as a determinant of sarcosaprophagous fly assemblages of sanitary interest: a comparative field study between larviparous and oviparous reproductive strategies.

In Diptera, reproductive strategies vary according to the stage of development of the newly deposited offspring and their abundance. The aim of our study is to establish connections between the reproductive strategies of flies (larviparous or oviparous) and the prevailing local conditions (sun or shade) as well as landscape attributes (low or high urbanization) in an urban setting. We collected flies using 2 baited traps (in the sun or shade) at each of the 13 study sites with varying levels of urbanization. We used generalized linear mixed models to examine the impact of landscape and local characteristics on the diversity (abundance and richness of larviparous and oviparous Diptera) of sarcosaprophagous flies. Our findings indicate that while the abundance and diversity of both larviparous and oviparous flies are affected by urbanization, larviparous flies would be less sensitive to more urbanized environments. Larviparous also exhibit a preference for resources under sun exposure, while the responses of oviparous seem more species-dependent. The observed patterns can be explained by the known biology of the studied groups.

"Ripping Off the Band-Aid": uncovering future health care Professionals' "Fractured Knowledge" about sexual and reproductive health.

Background: Research has shown the role of identity on future health professionals' confidence and competence in addressing the sexual and reproductive health (SRH) needs of their patients. While there has been some work in increasing the sexual health literacy of future providers via various curricular approaches and comprehensive clinical-based training, there are research gaps on how social differences around identity impact future healthcare professionals' knowledge and practices around SRH. Objectives: This article presents research findings on the experiences of US undergraduate students attending a campus that provides training in the health sciences and health professions. Our study aims to understand the perspectives of these students as they pertain to their future career choices in healthcare, with a focus on how their past experiences learning about sex, sexuality, and reproduction impact their current and future professional trajectories. Methods: We present a qualitative analysis from 40 in-depth interviews with U.S. undergraduates. The interview questions were designed in collaboration with undergraduate researchers interested in sexual health education. These student researchers collected all the interview data and worked with senior researchers to analyze some of these data. Results: The themes that emerged from the interviews were around experiences with what students perceived as "fractured" sexual and reproductive health (SRH) knowledge they received as children and adolescents. This knowledge shaped essential aspects of their identity as young adults and future healers. Data indicated unique processes implicated in how past as well as present socialization experiences learning about sex, sexuality, and reproduction positions undergraduates in health professions to see young adulthood as a journey of "catching up" on sexual knowledge but also as an ongoing experience of anticipation and planning influencing their career-building journey. Conclusions: The importance of sexual health literacy among healthcare professionals cannot be overstated, as it is vital in providing patient-centered and non-judgmental sexual and reproductive health (SRH) care and services. To date, there is a shortage of studies looking at the impact of sexual health knowledge on healthcare professionals. More research is needed on educational strategies that could be implemented at the intra-personal level to assist college-aged young adults in healthcare career tracks to "catch up" or "fill in the gaps" in their sexual education journey.

Dietary intake of fatty acids and its relationship with FEV1/FVC in patients with chronic obstructive pulmonary disease.

BACKGROUND & AIMS: The deterioration of pulmonary function has been associated with increased levels of systemic inflammation that can be stimulated by consumption of saturated fatty acids and trans fats. We hypothesized that fatty acids intake impact on pulmonary function. However, evidence about the impact of different types of fatty acids on pulmonary function in patients with chronic obstructive pulmonary disease (COPD) is limited and heterogeneous. The aim of this study was to evaluate the association between intake of fatty acids and pulmonary function in patients with COPD. METHODS: Cross sectional study of patients diagnosed with COPD. The relationship between consumption of fatty acids and the FEV1/FVC ratio obtained by spirometry was assessed. Patients with exacerbations during the prior 2 months, diagnosis of asthma or administration of a dietary supplement were excluded. RESULTS: A simple linear regression showed that for each gram of carbohydrates and total l fatty acids intake, the FEV1/FVC ratio decreased -0.03 ml (ß: -0.03, 95% CI -0.06 to -0.01, p = 0.008) and -0.009 ml (ß: -0.00, 95% CI -0.02 to 0.00, p = 0.031) respectively. Pentadecanoic acid (C15:0) was associated with an increase of 0.47 ml in the FEV1/FVC ratio for each milligram intake (ß: 0.47, 95% CI 0.04 to 0.91, p = 0.031). Subsequently, when adjusted for calories intake, an increase of 0.53 ml was observed in the FEV1/FVC for each milligram of C15:0 fatty acid intake (ß:0.53, 95% CI 0.09 to 0.97, p = 0.018). CONCLUSION: A positive association was observed between pentadecanoic acid and the FEV1/FVC ratio with a beneficial effect on patients with COPD.
