ABSTRACT

BACKGROUND: Men who have sex with men (MSM) are at heightened risk for HIV acquisition, yet they may delay or avoid HIV testing due to intersectional stigma experienced at the healthcare facility (HCF). Few validated scales exist to measure intersectional stigma, particularly amongst HCF staff. We developed the Healthcare Facility Staff Intersectional Stigma Scale (HCF-ISS) and assessed factors associated with stigma in Ghana. METHODS: We analyzed baseline data from HCF staff involved in a study testing a multi-level intervention to reduce intersectional stigma experienced by MSM. Data are from eight HCFs in Ghana (HCF Staff n = 200). The HCF-ISS assesses attitudes and beliefs towards same-sex relationships, people living with HIV (PLWH) and gender non-conformity. Exploratory factor analysis assessed HCF-ISS construct validity and Cronbach's alphas assessed the reliability of the scale. Multivariable regression analyses assessed factors associated with intersectional stigma. RESULTS: Factor analysis suggested an 18-item 3-factor scale including: Comfort with Intersectional Identities in the Workplace (6 items, Cronbach's alpha = 0.71); Beliefs about Gender and Sexuality Norms (7 items, Cronbach's alpha = 0.72); and Beliefs about PLWH (5 items, Cronbach's alpha = 0.68). Having recent clients who engage in same-gender sex was associated with greater comfort with intersectional identities but more stigmatizing beliefs about PLWH. Greater religiosity was associated with stigmatizing beliefs. Infection control training was associated with less stigma towards PLWH and greater comfort with intersectional identities. CONCLUSIONS: Achieving the goal of ending AIDS by 2030 requires eliminating barriers that undermine access to HIV prevention and treatment for MSM, including HCF intersectional stigma. The HCF-ISS provides a measurement tool to support intersectional stigma-reduction interventions.

ABSTRACT

Maisonneuve fractures are relatively well known in the sports medicine, and orthopedic communities, however, can be commonly missed among primary care providers. The following case outlines an active duty 35-yr-old female patient who presented with acute pain on the left ankle and lower leg after she misjudged a step. The injury is a combination of high fibular and medial malleolar fractures with a disruption of the tibiofibular syndesmosis ligaments. This is a result of extreme external rotation and pronation of a fixed foot. The proper diagnosis is reliant on ankle and tibiofibular films, to include orthogonal views. This case serves as a reminder to always examine joints above and below the injury site, obtain orthogonal views of a fracture, as well as the unstable nature of syndesmosis injuries. This fracture is commonly a sports-related injury; thus, it is particularly important for military providers to be aware of Maisonneuve fractures and the common pitfalls in diagnosis and treatment.

ABSTRACT

Central serous retinopathy (CSR) is a disease process that involves accumulation of serous fluid within the macular retina. This fluid accumulation can temporarily or permanently disrupt vision and in many patients is often a recurrent problem. This case describes recurrent CSR in an experienced U.S. Naval F/A-18 fighter pilot. The patient had been troubled by recurrent CSR for several years which required him to be removed from a flying status. After several episodes and treatment with laser photocoagulation and finasteride, the patient's vision and disease process stabilized, but with permanent defective visual acuity in the right eye. There have been many case reports documenting CSR in active duty military aviators worldwide, including flying pilots who have residual permanent loss of visual acuity; however, this is the first U.S. Naval pilot who has been granted a waiver to return to unrestricted flight status with permanent defective visual acuity.

ABSTRACT

Sea anemone actinoporins constitute an optimum model to investigate mechanisms of membrane pore formation. All actinoporins of known structure show a general fold of a ß-sandwich motif flanked by two α-helices. The crucial structure for pore formation seems to be the helix located at the N-terminal end. The role of several other protein regions in membrane attachment is also well established. However, not much is known about the protein residues involved in the oligomerization required for pore formation. Previous detailed analysis of the soluble three-dimensional structures of different wild-type and mutant actinoporins from Stychodactyla helianthus suggested residues which could be involved in this oligomerization. One of these stretches contains a conserved sequence compatible with an integrin-binding RGD motif. The results presented now deal with mutants affecting this motif in the well-characterized actinoporin sticholysin II. Small modifications along this three-residue sequence had profound effects on its solubility. Just a single methyl group yielded an RAD mutant version with a highly diminished haemolytic activity and altered oligomerization behaviour. The results obtained are discussed in terms of a key role for the RGD motif in maintaining the actinoporins' pore-competent state of protein oligomerization.
