RESUMO

BACKGROUND: For adults living with HIV (ALHIV) and comorbidities, access to comprehensive healthcare services is crucial to achieving optimal health outcomes. This study aims to describe lived experiences, challenges, and coping strategies for accessing care for hypertension and/or diabetes (HTN/DM) in HIV care and treatment clinics (CTCs) and other healthcare settings. METHODOLOGY: We conducted a qualitative study that employed a phenomenological approach between January and April 2022 using a semi-structured interview guide in six HIV CTCs in Dar es Salaam, Tanzania. We purposively recruited 33 ALHIV with HTN (n = 16), DM (n = 10), and both (n = 7). Thematic content analysis was guided by the 5As framework of access to care. FINDINGS: The majority of the participants were females, between the ages of 54-73, and were recruited from regional referral hospitals. HIV CTCs at regional referral hospitals had more consistent provision of HTN screening services compared to those from district hospitals and health centers. Participants sought HTN/DM care at non-CTC health facilities due to the limited availability of such services at HIV CTCs. However, healthcare delivery for these conditions was perceived as unaccommodating and poorly coordinated. The need to attend multiple clinic appointments for the management of HTN/DM in addition to HIV care was perceived as frustrating, time-consuming, and financially burdensome. High costs of care and transportation, limited understanding of comorbidities, and the perceived complexity of HTN/DM care contributed to HTN/DM treatment discontinuity. As a means of coping, participants frequently monitored their own HTN/DM symptoms at home and utilized community pharmacies and dispensaries near their residences to check blood pressure and sugar levels and obtain medications. Participants expressed a preference for non-pharmaceutical approaches to comorbidity management such as lifestyle modification (preferred by young participants) and herbal therapies (preferred by older participants) because of concerns about side effects and perceived ineffectiveness of HTN/DM medications. Participants also preferred integrated care and focused patient education on multimorbidity management at HIV CTCs. CONCLUSION: Our findings highlight significant barriers to accessing HTN/DM care among ALHIV, mostly related to affordability, availability, and accessibility. Integration of NCD care into HIV CTCs, could greatly improve ALHIV health access and outcomes and align with patient preference.

RESUMO

In the absence of electric light, sleep for humans typically starts soon after dusk and at higher latitudes daily sleep timing changes seasonally as photoperiod changes. However, access to electric light shields humans from natural photoperiod changes, and whether seasonal changes in sleep occur despite this isolation from the natural light-dark cycle remains a matter of controversy. We measured sleep timing in over 500 university students living in the city of Seattle, WA (47.6°N) throughout the four seasons; we show that even when students are following a school schedule, sleep timing is delayed during the fall and winter. For instance, during the winter school days, students fell asleep 35 min later and woke up 27 min later (under daylight-savings time) than students during the summer school days, a change that is an hour larger relative to solar midnight. Furthermore, chronotype defined by mid-sleep on free days corrected for oversleep (MSFc), an indirect estimate of circadian phase, was more than 30 min later in the winter compared with the summer. Analysis of the effect of light exposure showed that the number of hours of light exposure to at least 50 lux during the daytime was a stronger predictor of MSFc than the exposure time to this illuminance after dusk. Specifically, MSFc was advanced by 30 min for each additional hour of light exposure during daytime and delayed by only 15 min for each additional hour of postdusk exposure to light. Additionally, the time of the day of exposure to high light intensities was more predictive of MSFc when daytime exposure was considered than when exposure for the full 24-h day was considered. Our results show that although sleep time is highly synchronized to social time, a delayed timing of sleep is evident during the winter months. They also suggest that daily exposure to daylight is key to prevent this delayed phase of the circadian clock and thus circadian disruption that is typically exacerbated in high-latitude winters.

RESUMO

Patient safety (PS) and quality improvement (QI) have gained momentum over the last decade and are becoming more integrated into medical training, physician reimbursement, maintenance of certification, and practice improvement initiatives. While PS and QI are often lumped together, they differ in that PS is focused on preventing adverse events while QI is focused on continuous improvements to improve outcomes. The pillars of health care as defined by the 1999 Institute of Medicine report "To Err is Human: Building a Safer Health System" are safety, timeliness, effectiveness, efficiency, equity, and patient-centered care. Implementing a safety culture is dependent on all levels of the health care system. Part 1 of this CME will provide dermatologists with an overview of how PS fits into our current health care system and will include a focus on basic QI/PS terminology, principles, and processes. This article also outlines systems for the reporting of medical errors and sentinel events and the steps involved in a root cause analysis.

RESUMO

Quality improvement (QI) in medicine is reliant on a team-based approach and an understanding of core QI principles. Part 2 of this continuing medical education series outlines the steps of performing a QI project, from identifying QI opportunities, to carrying out successive Plan-Do-Study-Act cycles, to hard-wiring improvements into the system. QI frameworks will be explored and readers will understand how to interpret basic QI data.

RESUMO

Rapid human-to-human transmission of monkeypox has created a public health emergency requiring prompt, multidisciplinary attention. Dermatologists are at the forefront of diagnosis due to the disease-defining skin lesions. Moreover, patients with pre-existing skin disease and those who are on immunosuppressive medications for skin disease may be at increased risk of severe infection. In this review, a panel of authors with expertise in complex medical dermatology and managing patients on immunosuppression reviews the literature and provides initial guidance for diagnosis and management in dermatology practices. Though there are knowledge gaps due to a lack of controlled studies, we support use of replication-deficit vaccines in all dermatologic patients who meet qualifying risk or exposure criteria. We offer strategies to optimize vaccine efficacy in patients with immunosuppression. We discuss alternative post-exposure treatments and their safety profiles. Finally, we outline supportive care recommendations for cutaneous manifestations of monkeypox. Large scale epidemiologic investigations and clinical trials will ultimately revise and extend our guidance.

RESUMO

Visual object perception involves neural processes that unfold over time and recruit multiple regions of the brain. Here, we use high-density EEG to investigate the spatiotemporal representations of object categories across the dorsal and ventral pathways. In , human participants were presented with images from two animate object categories (birds and insects) and two inanimate categories (tools and graspable objects). In , participants viewed images of tools and graspable objects from a different stimulus set, one in which a shape confound that often exists between these categories (elongation) was controlled for. To explore the temporal dynamics of object representations, we employed time-resolved multivariate pattern analysis on the EEG time series data. This was performed at the electrode level as well as in source space of two regions of interest: one encompassing the ventral pathway and another encompassing the dorsal pathway. Our results demonstrate shape, exemplar, and category information can be decoded from the EEG signal. Multivariate pattern analysis within source space revealed that both dorsal and ventral pathways contain information pertaining to shape, inanimate object categories, and animate object categories. Of particular interest, we note striking similarities obtained in both ventral stream and dorsal stream regions of interest. These findings provide insight into the spatio-temporal dynamics of object representation and contribute to a growing literature that has begun to redefine the traditional role of the dorsal pathway.

RESUMO

Recurrent aphthous stomatitis (RAS) is a common chronic disease in the oral mucosa that affects about 20% of the population. It is characterized by solitary or multiple, recurrent, small ulcers with erythematous haloes and yellow/gray floors. RAS can be managed through a wide variety of preventative measures and therapies, intending to reduce ulcer pain, stimulate ulcer healing, and/or prevent ulcer recurrence. First-line treatment options include topical medications in the form of corticosteroids (triamcinolone acetonide), anti-inflammatory drugs (amlexanox), antibiotics (doxycycline), and antiseptics (lidocaine). In more severe cases of RAS where local treatment is insufficient, systemic drugs in the form of corticosteroids (prednisone), immunomodulatory drugs (thalidomide), and antibiotics/antimicrobials (clofazimine) can prove effective. This review will summarize current treatment options for RAS with discussion of prevention, topical measures, natural treatments, systemic therapies, and new potential therapies. Furthermore, this review will provide recommendations on therapeutic options for RAS based on disease severity and patient circumstances.

RESUMO

The emergency department (ED) is a frequent source of care for pediatric patients with dermatologic conditions, possibly owing to limited access to routine and urgent outpatient dermatology appointments. The demographics, clinical characteristics, follow-up scheduling practices, and attendance rates of 50 pediatric and 142 adult patients evaluated by the dermatology consult service in the ED were reviewed. High rates of follow-up attendance were observed in the pediatric and adult populations, with the majority receiving an appointment within 2 weeks. The dermatology consult service may play an important role in facilitating post-discharge access to outpatient care.

RESUMO

BACKGROUND: Over the past several years, hyperdilute calcium hydroxylapatite (CaHA) has emerged as an effective modality for improving skin quality and managing laxity in the face, arms, hands, neck, décolletage, upper arms, abdomen, buttocks, and upper legs, as well as for treating cellulite and striae. Whereas undiluted CaHA is used to provide volume, hyperdilute CaHA is distributed across a much larger surface area in a more superficial plane to stimulate neocollagenesis and elastin formation over time. The absence of lymphocytic infiltrates and predominance of type 1 collagen in the tissue response to CaHA make hyperdilute CaHA a valuable tool for nonsurgical skin tightening. OBJECTIVES: The aim of this study was to provide practical step-by-step guidance on patient selection, dilution practices, and optimal injection technique to facilitate incorporation of the technique into clinical practice. METHODS: Over the course of 3 regional meetings in the United States, 12 expert physician injectors participated in live webinars as part of a continuing medical education program. RESULTS: The practical guidance in this manuscript is based upon the most frequently requested information by audience members and the information considered critical for success by the authors. CONCLUSIONS: The minimally invasive nature of filler injection results in little downtime, making this treatment particularly appealing. The recommendations presented are consistent with previously published consensus guidelines on hyperdilute CaHA but are intended to serve as "how-to" guidance based on the experience of expert injectors who have successfully treated the face and body.

RESUMO

Spanish is the leading non-English language in the United States, with more than 41 million speakers. The Hispanic population has one of the lowest health literacy rates. Amongst Spanish speakers, limited English proficiency can contribute to poorer health outcomes and greater health disparities, such as lower quality of care received. We sought to assess the availability and readability scores of Spanish-language dermatologic patient education materials (PEMs) compared with those materials in English.

RESUMO

Language-congruent care can improve clinical outcomes. As a quality improvement initiative supported by the Department of Dermatology at Massachusetts General Hospital, the American Academy of Dermatology, and the Society for Pediatric Dermatology, our group established monthly pediatric dermatology "Spanish clinics" that scheduled Spanish-speaking patients on the same day and utilized a dedicated, live interpreter who stayed with the clinical team throughout the clinic. Patients reported high satisfaction scores, averaging 9.8 out of 10, and 90.5% of patients preferred this model to traditional appointments. Our participating physician found "Spanish clinics" allowed for more efficient care not only in the monthly pilot clinics, but in all clinics occurring during the time period.

RESUMO

To accomplish the deceptively simple task of perceiving the size of objects in the visual scene, the visual system combines information about the retinal size of the object with several other cues, including perceived distance, relative size, and prior knowledge. When local component elements are perceptually grouped to form objects, the task is further complicated because a grouped object does not have a continuous contour from which retinal size can be estimated. Here, we investigate how the visual system solves this problem and makes it possible for observers to judge the size of perceptually grouped objects. We systematically vary the shape and orientation of the component elements in a two-alternative forced-choice task and find that the perceived size of the array of component objects can be almost perfectly predicted from the distance between the centroids of the component elements and the center of the array. This is true whether the global contour forms a circle or a square. When elements were positioned such that the centroids along the global contour were at different distances from the center, perceived size was based on the average distance. These results indicate that perceived size does not depend on the size of individual elements, and that smooth contours formed by the outer edges of the component elements are not used to estimate size. The current study adds to a growing literature highlighting the importance of centroids in visual perception and may have implications for how size is estimated for ensembles of different objects.

RESUMO

The current development to employ magnetic skyrmions in novel spintronic device designs has led to a demand for room-temperature-stable skyrmions of ever smaller size. We present extensive studies on skyrmion stability in atomistic magnetic systems in two- and three-dimensional geometries. We show that for materials described by the same micromagnetic parameters, the variation of the atomistic exchange between different neighbors, the stacking order, and the number of layers of the atomic lattice can significantly influence the rate of the thermally activated decay of a skyrmion. These factors alone are important considerations, but we show that their combination can open up novel avenues of materials design in the search for sub-10 nm skyrmions, as their lifetime can be extended by several orders of magnitude.

RESUMO

Online coupon retailers and pharmacies are popular sites that patients can access discounted medications when compared to cash prices. These sources are especially important for those patients without insurance. In our study, we analyzed commonly prescribed topical and oral medications and compared the cash prices to the discounted medications based on a typical month of usage. We found savings in every one of the medications that we analyzed, some with savings up to hundreds of dollars. Savings were present in all the sources analyzed, with the coupon-based programs often having the lowest price. We suggest certain alternative prescribing guidelines when considering patients who may not be able to afford cash prices of medications. Our hopes with this study are to quantify savings for discounted medications as well as to help physicians target more affordable medications for their patients.

RESUMO

Background: Autoimmune connective tissue diseases (ACTDs) are a broad range of diseases featured by immune dysregulation, and often have multisystem involvement with prominent skin manifestations. Pruritus is one of the most common symptoms in these diseases, with significant impact on the quality of life of patients. Objective: To characterize the frequency, location, severity, and timing relative to disease onset of pruritus in different ACTDs. Methods: A chart review of all patients seen in the Rheumatology-Dermatology clinic at Massachusetts General Hospital. Results: Itch was a troubling symptom in 83% of dermatomyositis (DM), 61% of systemic lupus erythematosus (SLE), 59% of Sjogren syndrome (SJO), 22% of systemic sclerosis (SSc), and 60% of mixed connective tissue disease. In DM and SLE, itch paralleled the course of inflammatory skin manifestations in 83% and 45%, respectively. Itch in DM is more intense and more treatment resistant in 12% vs 1% in SLE. In contrast, itch in SSc and SJO tended to occur later in the disease course, 86% vs 42%, respectively. Conclusion: Itch is common in all ACTDs and often under-evaluated and under treated. Pruritus is more common and more severe in DM than in SLE. Treatment of pruritus in ACTDs can be challenging, and sometimes multi-modal therapy is warranted. J Drugs Dermatol. 2019;18(10):995-998.

RESUMO

The motion-induced contour (MIC) was first described by Victor Klymenko and Naomi Weisstein in a series of papers in the 1980s. The effect is created by rotating the outline of a tilted cube in depth. When one of the vertical edges is removed, an illusory contour can be seen in its place. In four experiments, we explored which stimulus features influence perceived illusory contour strength. Participants provided subjective ratings of illusory contour strength as a function of orientation of the stimulus, separation between inducing edges, and the length of inducing edges. We found that the angle of tilt of the object in depth had the largest impact on perceived illusory contour strength with tilt angles of 20° and 30° producing the strongest percepts. Tilt angle is an unexplored feature of structure-from-motion displays. In addition, we found that once the depth structure of the object was extracted, other features of the display, such as the distance spanned by the illusory contour, could also influence its strength, similar to the notion of support ratio for 2-D illusory contours. Illusory contour strength was better predicted by the length of the contour in 3-D rather than in 2-D, suggesting that MICs are constructed by a 3-D process that takes as input initially recovered contour orientation and position information in depth and only then forms interpolations between them.
