Second cohomology for finite groups of Lie type

Let $G$ be a simple, simply-connected algebraic group defined over $\mathbb{F}_p$. Given a power $q = p^r$ of $p$, let $G(\mathbb{F}_q) \subset G$ be the subgroup of $\mathbb{F}_q$-rational points. Let $L(\lambda)$ be the simple rational $G$-module of highest weight $\lambda$. In this paper we establish sufficient criteria for the restriction map in second cohomology $H^2(G,L(\lambda)) \rightarrow H^2(G(\mathbb{F}_q),L(\lambda))$ to be an isomorphism. In particular, the restriction map is an isomorphism under very mild conditions on $p$ and $q$ provided $\lambda$ is less than or equal to a fundamental dominant weight. Even when the restriction map is not an isomorphism, we are often able to describe $H^2(G(\mathbb{F}_q),L(\lambda))$ in terms of rational cohomology for $G$. We apply our techniques to compute $H^2(G(\mathbb{F}_q),L(\lambda))$ in a wide range of cases, and obtain new examples of nonzero second cohomology for finite groups of Lie type.Comment: 29 pages, GAP code included as an ancillary file.

Pharmacists’ use of guidelines for the supply of non-prescription medicines: a cross-sectional survey

Objectives: Guidelines support best practice for healthcare practice. In Australia, some non-prescription medicines are only accessible after consultation with a pharmacist and are known as Pharmacist Only medicines. Guidelines for providing some Pharmacist Only medicines are available, however, it is currently unknown if and how these guidelines are used in practice.// The objective was to characterise pharmacists’, intern pharmacists and pharmacy students’ use of guidelines for Pharmacist Only medicines.// Methods: A cross-sectional electronic survey of Australian registered pharmacists, intern pharmacists and pharmacy students was administered in July 2020. Questions explored the participants’ use of Pharmacist Only medicine guidelines (available both in print and online; available online only) in the preceding 12 months. Data were analysed descriptively (i.e. frequencies, percentages).// Key findings: In total, 574 eligible respondents completed the survey. Overall, 396 (69%) reported accessing the online and in-print guidelines in the previous 12 months with 185 (33%) accessing online-only guidelines. The guideline on emergency contraception was used the most out of all guidelines in the past 12 months (278, 48%). Overall, respondents reported accessing guidelines to update knowledge, check their practice reflected best practice and content familiarisation. Respondents’ reasons for not accessing guidelines were due to respondents stating they did not need the information or that they had previously accessed the guidelines more than 12 months ago. These reasons varied between respondent groups.// Conclusions: Access and use of the Pharmacist Only medicines guidelines varied between pharmacists, interns and students. Further understanding of the influences of the use of these guidelines will help inform professional bodies on how best to develop guidelines to increase consistent use in practice and implement interventions to increase use./

Use of a reference text by pharmacists, intern pharmacists and pharmacy students: a national cross-sectional survey

Background: Reference texts assist pharmacists by addressing knowledge gaps and enabling evidence-based decisions when providing patient care. It is unknown whether reference text utilisation patterns differ between pharmacists, intern pharmacists and pharmacy students. To describe and compare the self-reported use and perceptions of a reference text, namely the national formulary, by pharmacists, intern pharmacists and pharmacy students. // Methods: Registered pharmacists, intern pharmacists and pharmacy students living in Australia were surveyed in July 2020. The survey was electronic and self-administered. Questions considered self-reported use of a specific reference text in the preceding 12 months. // Key findings: There were 554 eligible responses out of 774 who commenced the survey: 430 (78%) pharmacists, 45 (8%) intern pharmacists and 79 (14%) pharmacy students. Most participants (529/554, 96%) reported historical use of the text, though pharmacists were significantly less likely than intern pharmacists and students to use it frequently (52/422, 12% versus 16/43, 37% versus 23/76, 30%, P < 0.001). Pharmacists (44%, 177/404) reported using the text as a tool to resolve a situation when providing a service or patient care (177/404, 44%) or as a teaching resource (150/404, 38%). In contrast, intern pharmacists and students most commonly use these to familiarise themselves with the contents (30/43, 70%; 46/76, 61%) or update their knowledge (34/43, 79%; 53/76, 70%). // Conclusions: Access and use patterns varied significantly across career stages. A broader understanding of the use of reference texts may help develop interventions to optimise the content and usability. Varying usage patterns across the groups may inform the tailoring of texts for future use

Absorbent articles, especially catamenials, having improved fluid directionality

The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels

Chemosensory Contributions of E-Cigarette Additives on Nicotine Use

While rates of smoking combustible cigarettes in the United States have trended down in recent years, use of electronic cigarettes (e-cigarettes) has dramatically increased, especially among adolescents. The vast majority of e-cigarette users consume “flavored” products that contain a variety of chemosensory-rich additives, and recent literature suggests that these additives have led to the current “teen vaping epidemic.” This review, covering research from both human and rodent models, provides a comprehensive overview of the sensory implications of e-cigarette additives and what is currently known about their impact on nicotine use. In doing so, we specifically address the oronasal sensory contributions of e-cigarette additives. Finally, we summarize the existing gaps in the field and highlight future directions needed to better understand the powerful influence of these additives on nicotine use
