RESUMO

Determining the composition of protein complexes is an essential step toward understanding the cell as an integrated system. Using coaffinity purification coupled to mass spectrometry analysis, we examined protein associations involving nearly 5,000 individual, FLAG-HA epitope-tagged Drosophila proteins. Stringent analysis of these data, based on a statistical framework designed to define individual protein-protein interactions, led to the generation of a Drosophila protein interaction map (DPiM) encompassing 556 protein complexes. The high quality of the DPiM and its usefulness as a paradigm for metazoan proteomes are apparent from the recovery of many known complexes, significant enrichment for shared functional attributes, and validation in human cells. The DPiM defines potential novel members for several important protein complexes and assigns functional links to 586 protein-coding genes lacking previous experimental annotation. The DPiM represents, to our knowledge, the largest metazoan protein complex map and provides a valuable resource for analysis of protein complex evolution.

RESUMO

BACKGROUND: Zambian adolescent girls and young women (AGYW) have high HIV incidence and face barriers to the use of pre-exposure prophylaxis (PrEP). Parental support improves PrEP use and adherence in some settings, but negative parental attitudes toward HIV prevention may inhibit engagement with AGYW. We explored perceptions of future PrEP methods among AGYW and parents and parent-youth engagement on HIV prevention and PrEP use. METHODS: We conducted a qualitative descriptive study among AGYW and parents of AGYW in five provinces in Zambia in September-October 2021. We conducted 10 focus group discussions (FGDs) and four in-depth interviews (IDIs) with AGYW participants (n = 87) and seven FGDs and four IDIs among parents of AGYW (n = 62). All FGDs and IDIs were audio-recorded, transcribed verbatim, and analyzed to identify qualitative themes. RESULTS: Most AGYW participants preferred the discreet nature and longer duration of injectable PrEP compared to the PrEP ring and oral PrEP. Many AGYWs reported inability to disclose PrEP use to their parents due to lack of parental support based on cultural taboos against premarital sex. Nevertheless, AGYW participants said they would like to talk to their parents about PrEP so their parents could support their use. Many parents also described difficulties discussing PrEP with their daughters because of cultural and religious beliefs about abstinence from sex before marriage. However, parents acknowledged that the threat of HIV is real and said they need PrEP knowledge and guidance on speaking with their children about HIV prevention and PrEP. CONCLUSIONS: Although many parents are currently not playing a role in daughters' decisions about PrEP use, both parents and AGYW are willing to engage with each other on HIV prevention issues. To foster parent-child engagement, HIV prevention programs should not only provide information about PrEP but also address social norms that impede discussion of HIV prevention and equip both parents and AGYW with skills and support for such conversations. Community sensitization is also needed as new PrEP products are introduced, to create an enabling environment for parent-child engagement by increasing awareness, countering misconceptions, and reducing stigma.

RESUMO

BACKGROUND AND OBJECTIVES: Fractional radiofrequency devices have been demonstrated to improve skin texture, such as smoothness, rhytides, brightness, and atrophic acne scars, by increasing dermal thickness, dermal collagen content, and dermal fibrillin content. The objective of the study is to assess the efficacy and adverse effects of this device on Asian patients of skin type III and IV with skin textural changes. MATERIALS AND METHODS: The study was designed as a prospective, open-labeled single-arm study, which was conducted with 20 Chinese patients aged 21-60 years and having irregularities in their skin texture, rhytides, and acne scars. The patients received six treatments at intervals of 4 weeks. Treatment was initiated with the maximum energy tolerated, which was then adjusted during the course of treatment if the patients felt excessive discomfort. A total of two passes were delivered in each session. Physician assessment results and standardized photographs were collected at the baseline, after all treatment visits, and at 1, 2, and 6 months after the final treatment visit. RESULTS: A total of 17 patients completed the study according to the established protocol. At the 6-month follow-up, 71% of patients were satisfied and 24% of patients were very satisfied with the received treatments, and the treatment physician reported varying degrees of improvement based on the global assessment scale in 60% of the subjects. While the anticipated side effects, such as erythema, edema, pinpoint bleeding, scab formation, and flare of acne, were noted in the patients, no serious adverse effects occurred. CONCLUSION: The use of fractional radiofrequency improves skin texture and is safe for use in Asian patients of skin type III and IV. No long-term serious adverse effects were noted.

RESUMO

OBJECTIVE: Our study aimed to evaluate the efficacy of this novel dermal cooling system (DCS) in reducing pigmentation in benign pigmented lesions in Asian patients and its potential side effects. METHODS: It was a prospective open-label single-center study. Asian patients, with the presence of benign pigmented lesions mainly including lentigines, melasma, nevus spilus, ephelides, café au lait, and seborrheic keratosis were recruited for a novel DCS. The DCS provided localized cooling of the epidermal layer below freezing but was less intense than cryotherapy. Each patient received DCS at Week 0 and repeated at 4-week intervals up to 10 sessions. Global aesthetic improvement scores (GAIS) by blinded physicians and subjects were recorded at 2, 6, and 12 months posttreatment follow-up. RESULTS: Eighty-one patients were recruited with a total of 305 sessions performed and 1716 lesion sites treated. At 2-month posttreatment, 76.5% and 58.6% treatment sites showed obvious to marked improvement respectively and the improvement sustained at 6 and 12 months. Only minor adverse events were reported. Erythema and edema were the most commonly anticipated effects immediately after treatment. The pain was minimal. Postinflammatory hyperpigmentation was only reported in 2.2% (38/1716) treated sites. CONCLUSION: To our knowledge, this study was the first study to demonstrate that this novel DCS was an effective, safe, and well-tolerated treatment for benign pigmented lesions in Asians.

RESUMO

SUMMARY: T cells participate directly in the body's immune response to cancer, allowing immunotherapy treatments to effectively recognize and target cancer cells. We previously developed DeepCAT to demonstrate that T cells serve as a biomarker of immune response in cancer patients and can be utilized as a diagnostic tool to differentiate healthy and cancer patient samples. However, DeepCAT's reliance on tumor bulk RNA-seq samples as training data limited its further performance improvement. Here, we benchmarked a new approach, AutoCAT, to predict tumor-associated TCRs from targeted TCR-seq data as a new form of input for DeepCAT, and observed the same level of predictive accuracy. AVAILABILITY AND IMPLEMENTATION: Source code is freely available at https://github.com/cew88/AutoCAT, and data is available at 10.5281/zenodo.5176884. SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

RESUMO

Interleukin-22 (IL-22) is highly induced in response to infections with a variety of pathogens, and its main functions are considered to be tissue repair and host defense at mucosal surfaces. Here we showed that IL-22 has a unique role during infection in that its expression suppressed the intestinal microbiota and enhanced the colonization of a pathogen. IL-22 induced the expression of antimicrobial proteins, including lipocalin-2 and calprotectin, which sequester essential metal ions from microbes. Because Salmonella enterica ser. Typhimurium can overcome metal ion starvation mediated by lipocalin-2 and calprotectin via alternative pathways, IL-22 boosted its colonization of the inflamed intestine by suppressing commensal Enterobacteriaceae, which are susceptible to the antimicrobial proteins. Thus, IL-22 tipped the balance between pathogenic and commensal bacteria in favor of a pathogen. Taken together, IL-22 induction can be exploited by pathogens to suppress the growth of their closest competitors, thereby enhancing pathogen colonization of mucosal surfaces.

RESUMO

Few longitudinal studies have measured contraceptive continuation past one year in sub-Saharan Africa. We surveyed 674 women who had been randomized to receive the three-month intramuscular contraceptive injectable (DMPA-IM), levonorgestrel (LNG) implant, or copper intrauterine device (IUD) during the Evidence for Contraceptive Options and HIV Outcomes (ECHO) trial in South Africa and Zambia and were subsequently followed for two additional years to explore method continuation, reasons for discontinuation, and access to implant and IUD removal services. We also conducted in-depth qualitative interviews with 39 participants. We estimated cumulative discontinuation probabilities using Kaplan-Meier estimates and assessed factors associated with discontinuation using Cox-proportional hazards models. The LNG implant continuation rate over the maximum 44-month study period was 60 percent, while rates for the copper IUD and DMPA-IM were 52 percent and 44 percent, respectively. Reasons for method discontinuation included side effects, particularly menstrual changes, and method stock-outs. Most implant and IUD users who sought removal were able to access services; however, room for improvement exists. In this cohort originally randomized to receive a contraceptive method and attend regular study visits, implants and IUDs continued to be highly acceptable over an additional two years, but facilities should continue to ensure that insertions and removals are available as requested.

RESUMO

BACKGROUND: "Self-care" for sexual and reproductive health (SRH) includes contraceptive methods and other supplies that people can use with or without the support of a healthcare provider. Self-administered tests, self-injection of injectable contraception, or self-removal of intrauterine devices (IUDs) can increase people's access to and autonomy over their own SRH. Objectives of this study were to assess women's current interest in and use of SRH self-care and explore key informants' (KI) opinions of self-care, especially during the COVID-19 pandemic. METHODS: Data for this study came from female participants in the longitudinal Contraceptive Use Beyond ECHO (CUBE) study, and KIs, including healthcare providers, in South Africa and Zambia between September 2020 and June 2021. For this analysis, we used data from a participant phone survey (n = 537), and from in-depth interviews (IDIs) completed with a sub-sample of women (n = 39) and KIs (n = 36). Survey data were analyzed with descriptive statistics, and IDI data were analyzed using applied thematic analysis. RESULTS: Female survey participants in South Africa were more interested in learning about emergency contraceptive pills, subcutaneous injectable contraception, and CycleBeads, while Zambian participants wanted more information and access to condoms. However, in IDIs in both countries, women described minimal experience with self-care beyond condom use. In the Zambian KI IDIs, COVID-19 led to increased self-care counseling on subcutaneous injectable contraception and HIV self-testing. KIs who do not counsel on self-care were concerned that women may harm themselves or blame the provider for difficulties. Two KIs thought that women could possibly self-remove IUDs, but most expressed concerns. Reported barriers to self-care included COVID movement restrictions, transport costs, lack of accessible pharmacies, women's low awareness, and possible stigma. CONCLUSIONS: Women surveyed reported interest in learning more about SRH self-care methods and resources, but in IDIs did not report extensive previous use besides condoms. KIs described some concerns about women's ability to use self-care methods. Counseling on and provision of self-care methods and supplies may have increased during the COVID-19 pandemic, but ensuring that self-care is more than just a temporary measure in health systems has the potential to increase access to SRH care and support women's autonomy and healthcare needs.


BACKGROUND: "Self-care" refers to healthcare that does not have to be given by a provider, but that people can use themselves. In sexual and reproductive health (SRH), this includes medicines or supplies like pills and injections that people can use to prevent or test for pregnancy or sexually transmitted infections. This study wanted to better understand women's interest in and use of SRH self-care and explore key informants' opinions of self-care, especially during the COVID-19 pandemic. METHODS: We surveyed 537 women in KwaZulu-Natal province, South Africa and Lusaka, Zambia in 2020­2021. We also conducted interviews with 39 women and 36 key informants, including healthcare providers, government officials, and community advocates. RESULTS: Women surveyed in South Africa were more interested than those in Zambia in learning more about self-care contraception, especially daily pills, emergency pills, and injections they could give themselves. In interviews, some key informants said that they do not tell women about self-care because they worried that women could hurt themselves or blame the provider if they experienced problems. COVID movement restrictions, transport costs, and inaccessible pharmacies were all barriers that key informants mentioned to accessing tests, tools, or contraceptive methods that women could give or use themselves. CONCLUSIONS: Women surveyed were interested in learning more about self-care and those interviewed reported minimal previous use of self-care methods besides condoms. Providers also have some concerns about women's ability to use self-care methods. Counseling on and providing self-care methods and supplies may have increased during COVID-19, but increasing access to self-care could help more women take care of their own sexual and reproductive healthcare.

RESUMO

INTRODUCTION: Individuals living in rural communities are at heightened risk for Alzheimer's disease and related dementias (ADRD), which parallels other persistent place-based health disparities. Identifying multiple potentially modifiable risk factors specific to rural areas that contribute to ADRD is an essential first step in understanding the complex interplay between various barriers and facilitators. METHODS: An interdisciplinary, international group of ADRD researchers convened to address the overarching question of: "What can be done to begin minimizing the rural health disparities that contribute uniquely to ADRD?" In this state of the science appraisal, we explore what is known about the biological, behavioral, sociocultural, and environmental influences on ADRD disparities in rural settings. RESULTS: A range of individual, interpersonal, and community factors were identified, including strengths of rural residents in facilitating healthy aging lifestyle interventions. DISCUSSION: A location dynamics model and ADRD-focused future directions are offered for guiding rural practitioners, researchers, and policymakers in mitigating rural disparities. HIGHLIGHTS: Rural residents face heightened Alzheimer's disease and related dementia (ADRD) risks and burdens due to health disparities. Defining the unique rural barriers and facilitators to cognitive health yields insight. The strengths and resilience of rural residents can mitigate ADRD-related challenges. A novel "location dynamics" model guides assessment of rural-specific ADRD issues.

RESUMO

Carbon Intensity Constraint Policies (CICPs) are vital for addressing climate change challenges and advancing sustainable development. Since 2010, China has rolled out three five-year CICPs. However, there is limited understanding of their impact on carbon emission performance (CEP). Addressing this, this study pioneers the exploration of the CICP's impact on China's CEP. Drawing from government intervention and green paradox theories, this study highlights a concerning scenario: local governments achieve emission targets via excessive intervention. For deeper insights, this study melds the overall technology frontier concept with a non-radial, non-angle directional distance function, introducing a novel efficiency model rooted in the Data Envelopment Analysis (DEA) method. This offers a CEP measure across 30 Chinese provincial regions from 2002 to 2019. Using the quasi-difference-in-differences (quasi-DID) and moderated mediation models, this study ascertains the presence of the green paradox, uncovers its reasons, and suggests mitigation strategies. The results indicate that high government intervention diminishes CEP. This negative effect intensifies under greater regional fiscal pressure. Alarmingly, local authorities' eagerness to meet targets shows a counterproductive, inverted N-shaped trend regarding CICPs' time-based influence on regional CEP. Moreover, the impact varies based on regional economic development levels and stages. This study has ensured the robustness of the findings via parallel trend tests, parallel exclusion policies, a strengthened quasi-DID framework, and diverse control variable configurations. This study underscores the need for more balanced government intervention. It offers valuable policy insights, guiding China's upcoming CICP phase to realize the ambition of peaking carbon by 2030 and achieving carbon neutrality by 2060.

RESUMO

OBJECTIVE: Story memory tasks are among the most commonly used memory tests; however, research suggests they may be less sensitive to memory decline and have a weaker association with hippocampal volumes than list learning tasks. To examine its utility, we compared story memory to other memory tests on impairment rates and association with hippocampal volumes. METHOD: Archival records from 1617 older adults (Mage = 74.41, range = 65-93) who completed the Wechsler Memory Scale - 4th edition (WMS-IV) Logical Memory (LM), Hopkins Verbal Learning Test - Revised (HVLT-R), and Brief Visuospatial Memory Test - Revised (BVMT-R) as part of a clinical neuropsychological evaluation were reviewed. Scores >1.5 SD below age-adjusted means were considered impaired, and frequency distributions were used to examine impairment rates. A subset of participants (n = 179) had magnetic resonance imaging (MRI) data that underwent image quality assessment. Partial correlations and linear regression analyses, accounting for age, education, and total intracranial volume (TIV), examined associations between memory raw scores and hippocampal volumes. RESULTS: For delayed recall, nearly half of the sample was impaired on HVLT-R (48.8%) and BVMT-R (46.1%), whereas a little more than a third was impaired on LM (35.7%). Better performance on all three measures was related to larger hippocampal volumes (r's =. 26-.43, p's < .001). Individually adding memory scores to regression models predicting hippocampal volumes improved the model fit for all measures. CONCLUSIONS: Despite findings suggesting that story memory is less sensitive to memory dysfunction, it was not differentially associated with hippocampal volumes compared to other memory measures. Results support assessing memory using different formats and modalities in older adults.

RESUMO

BACKGROUND: Nail squamous cell carcinoma (nSCC) is the most common nail unit malignancy. However, no studies to date have evaluated treatment options for nSCC based on recurrence data while controlling for invasion. OBJECTIVE: To identify temporal trends in nSCC treatment modalities and compare treatment outcomes based on invasion. METHODS AND MATERIALS: The authors performed a systematic review of articles published on PubMed, MEDLINE, and Scopus from inception to April 2020 reporting treatment of nSCC. The primary outcome was disease recurrence. RESULTS: Reports of nSCC treatments have increased in the past decade. Mohs micrographic surgery (MMS) is the most common treatment reported overall. The lowest recurrence rates for in situ nSCC were seen with wide surgical excision (WSE) and MMS. For invasive disease, the recurrence rates were lowest with amputation, MMS, and WSE. CONCLUSION: Complete surgical excision of nSCC with either WSE or MMS is associated with lower recurrence rates than limited excision and nonsurgical therapies, regardless of degree of invasion. The prognostic significance of in situ versus invasive disease remains unclear. Confirmation of complete excision may improve outcomes. Digital amputation is indicated for nSCC with bone invasion. Prospective studies and randomized controlled trials are needed to directly compare surgical modalities for nSCC.

RESUMO

BACKGROUND: Gay, bisexual, and other men who have sex with men (GBMSM) are at disproportionately higher risk of acquiring HIV and other sexually transmitted infections (STI). While HIV/STI testing rates among GBMSM are increasing worldwide, they remain suboptimal in a variety of settings. While many studies have attempted to evaluate the efficacy of a variety of community-based campaigns, including peer and reminder-based interventions on HIV/STI testing, however few have attempted to do so for a web drama series. OBJECTIVE: This study evaluates the effectiveness of a popular web drama video series developed by a community-based organization in Singapore for GBMSM on HIV and other STI testing behaviors. METHODS: The study is a pragmatic, randomized controlled trial to evaluate a popular web drama video series developed by a community-based organization in Singapore for GBMSM. A total of 300 HIV-negative, GBMSM men in Singapore aged 18 to 29 years old were recruited and block-randomized into the intervention (n=150) and control arms (n=150). Primary outcomes included changes in self-reported intention to test for, actual testing for, and regularity of testing for HIV, syphilis, chlamydia or gonorrhea, while secondary outcomes include changes in a variety of other knowledge-based and psychosocial measures at the end of the study period. RESULTS: Overall, 83.3% (125/150) of participants in the intervention arm completed the proof of completion survey, compared to 88.7% (133/150) in the control arm. We found improvements in self-reporting as a regular (at least yearly) tester for HIV (15.9% difference, 95% CI, 3.2% to 28.6%; P=.02), as well as chlamydia or gonorrhea (15.5% difference, 95% CI, 4.2% to 26.9%; P=.009), indicating that the intervention had positively impacted these outcomes compared to the control condition. We also found improvements in participants' intentions to test for HIV (16.6% difference, 95% CI, 4.3% to 28.9%; P=.009), syphilis (14.8% difference, 95% CI, 3.2% to 26.4%; P=.01), as well as chlamydia or gonorrhea (15.4% difference, 95% CI, 4.2% to 26.6%; P=.008), in the next 3 months, indicating that the intervention was effective in positively impacting intention for HIV and other STI testing among participants. CONCLUSIONS: There are clear benefits for promoting intentions to test regularly and prospectively on a broad scale through this intervention. This intervention also has potential to reach GBMSM who may not have access to conventional HIV and other STI prevention messaging, which have typically been implemented at sex-on-premises venues, bars, clubs, and in sexual health settings frequented by GBMSM. When coupled with community or population-wide structural interventions, the overall impact on testing will likely be significant.

RESUMO

BACKGROUND: Patients often utilize the Internet to seek information related to their care. This study assesses the readability of online patient educational materials for submental fat reduction. METHODS: Patient educational materials from the 12 most popular websites related to submental fat reduction were downloaded and assessed for readability grade level using 10 unique scales. RESULTS: Analysis of the 12 most popular websites (and corresponding 47 articles) revealed that patient educational materials were written, on average, at an 11th grade reading level. The Flesch Reading Ease score was 48.9 (range 39.8-59.2), representing a "difficult" level of reading. Mean readability grade levels (range 9-13th grade for individual websites) were as follows: Coleman-Liau, 11.1; Flesch-Kincaid, 10.8; FORCAST, 10.8; Fry Graph, 10.1; Gunning Fog, 12.7; New Dale-Chall, 10.1; New Fog Count, 11.8; Simple Measure of Gobbledygook, 11.7; Raygor, 6.7. No website was at the 6th grade reading level for patient educational materials recommended by the American Medical Association and National Institutes of Health. CONCLUSIONS: Online patient educational materials for submental fat reduction are written well above the recommended reading level. Recognition of disparities in health literacy is necessary to enable patients to make informed decisions and become active participants in their own care. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMO

OBJECTIVES: This study draws on qualitative insights on the barriers and facilitators to HIV testing, as well as perceptions of HIV self-testing (HIVST), to propose a framework to understand not only the benefits but also potential knock-on implications of introducing HIVST in the context of other STI testing. METHODS: We conducted semistructured, in-depth interviews with 30 gay, bisexual and other men who have sex with men aged 18 and 39 years old in Singapore. Interview topics included barriers and facilitators to HIV and other STI testing, as well as perceptions of HIVST. Interviews were audio-recorded, transcribed, coded and analysed using thematic analysis. RESULTS: For HIV testing, participants cited the perceived risk of acquiring, susceptibility to and symptoms of HIV as internal motivators, while social influence and accessibility of HIV testing services were external motivators. For STI testing, perceived symptoms and partner notification of STI were reported as internal and external motivators, respectively. Availability of bundle tests, starting a new relationship and instances of mandatory testing motivated both simultaneous HIV and other STI testing. The fear of a positive diagnosis and lack of confidentiality were cited as internal and external barriers to HIV testing, respectively, while low perceived severity of other STI and the cost of STI tests were cited as internal and external barriers to other STI testing, respectively. We identified pathways to HIV and other STI testing and discussed how the introduction of HIVST may reduce opportunities for other STI testing. CONCLUSIONS: The findings of this study suggest that introducing HIVST might weaken linkages to other STI testing if alternative strategies of promoting other STI testing are not simultaneously implemented. We recommend that future interventions address both the risks of HIV and other STI simultaneously, and that structural interventions promoting HIV and other STI preventions be balanced accordingly.

RESUMO

Despite having an initial verbal memory advantage over men, women have greater rates of Alzheimer's disease and more rapid cognitive decline once diagnosed. Moreover, although Alzheimer's disease is influenced by inflammation, which itself has known sex differences, no study has investigated whether sex differences in memory are moderated by peripheral inflammatory activity. To address this issue, we analyzed data from 109 individuals (50 women, Mage = 71.62, range = 55-87) diagnosed as cognitively normal, or having mild cognitive impairment or Alzheimer's disease dementia. We then followed the sample for 12 months, as part of a longitudinal study of aging and Alzheimer's disease. At baseline, we assessed levels of the inflammatory cytokines interleukin (IL)-1ß (IL-1ß), IL-6, and tumor necrosis factor-α (TNF-α) in plasma. At baseline and 12 months, we assessed verbal memory using the Rey Auditory Verbal Learning Test and nonverbal memory using the Brief Visuospatial Memory Test-Revised. As hypothesized, for the full sample, women exhibited stronger verbal (but not nonverbal) memory than men. In women, but not men, higher IL-1ß at baseline related to poorer verbal learning across both time points and delayed recall at 12 months. The effect of sex on memory also differed by IL-1ß level, with women exhibiting a memory advantage both at baseline and 12 months, but only for those with low-to-moderate IL-1ß levels. Therefore, high peripheral inflammation levels may lead to a sex-specific memory vulnerability relevant for Alzheimer's disease.

RESUMO

BACKGROUND AND OBJECTIVES: Facial melasma is a disfiguring pigmentation and occurs frequently with aging skin. Topical treatment alone was often suboptimal. A recent study showed that fractional picosecond laser has promising result in benign pigmentary lesions. This study aims to investigate the efficacy and safety of 1064 nm picosecond laser in treatment of facial melasma and skin rejuvenation in Asian skin. STUDY DESIGN/MATERIALS AND METHODS: Patients of Asian descent seeking treatment for facial melasma and skin rejuvenation were screened and recruited. Each patient received up to nine laser treatments at 4-6 weeks intervals with a fractionated nonablative 1064 nm picosecond laser. Baseline and posttreatment modified Melasma Area Severity Index (mMASI) and Global Aesthetic Improvement Scale (IGAS) were assessed by blinded investigators based on the clinical photographs. Subject overall satisfaction was assessed by the questionnaires after treatment. All adverse events were documented. RESULTS: Twenty patients were recruited with a median age of 52.7 ± 8.2 years. Three subjects had Fitzpatrick skin type III and 17 had skin type IV. All subjects received nine laser sessions. Over 70% of patients were satisfied with the treatment outcomes. There was a statistically significant improvement in mMASI which reduced from 10.8 at baseline to 2.7 and 3.6 at 6 and 12 weeks post-treatment, respectively (both P < 0.01). For skin rejuvenation, 70% reported at least a moderate improvement at 6 weeks of post-treatment. No major side-effect was reported. Erythema was the most frequent transient response, while some reported edema (1.1%). Both resolved spontaneously. None reported hypo- or hyperpigmentation after treatment. The overall mean pain scare (VAS) was 1.92. CONCLUSION: Fractionated non-ablative 1064 nm picosecond laser was effective in treatment of melasma and skin rejuvenation. It was also safe and well tolerated. Importantly, there was no hypo or hyperpigmentation reported. Lasers Surg. Med. 00:00-00, 2021. © 2021 Wiley Periodicals LLC.

RESUMO

Our objective was to assess the quality of acne-related medical information present on TikTok, the world's fastest growing social media platform. We queried the TikTok mobile application for videos tagged with "#acne" on May 1, 2020, and assessed the top 100 videos meeting inclusion criteria for content quality using DISCERN, a validated and reliable instrument for evaluating consumer health information. The mean content quality rating of videos was 2.03 (SD 0.47) which, according to the DISCERN instrument, indicates information with serious to potentially important shortcomings. Dermatologists should be aware that adolescents are using TikTok to gather acne-related information, and should prioritize acne education in this patient demographic due to the generally low content quality of such information.

RESUMO

BACKGROUND: Intensive glycemic control is of unclear benefit and carries increased risk for older adults with diabetes. The American Geriatrics Society's (AGS) Choosing Wisely (CW) guideline promotes less aggressive glycemic targets and reduction in pharmacologic therapy for older adults with type II diabetes. Meanwhile, behavioral economic (BE) approaches offer promise in influencing hard-to-change behavior, and previous studies have shown the benefits of using electronic health record (EHR) technology to encourage guideline adherence. OBJECTIVE: This study aimed to develop and pilot test an intervention that leverages BE with EHR technology to promote appropriate diabetes management in older adults. DESIGN: A pilot study within the New York University Langone Health (NYULH) EHR and Epic system to deliver BE-inspired nudges at five NYULH clinics at varying time points from July 12, 2018, through October 31, 2019. PARTICIPANTS: Clinicians across five practices in the NYULH system whose patients were older adults (age 76 and older) with type II diabetes. INTERVENTIONS: A BE-EHR module comprising six nudges was developed through a series of design workshops, interviews, user-testing sessions, and clinic visits. BE principles utilized in the nudges include framing, social norming, accountable justification, defaults, affirmation, and gamification. MAIN MEASURES: Patient-level CW compliance. KEY RESULTS: CW compliance increased 5.1% from a 16-week interval at baseline to a 16-week interval post intervention. From February 14 to June 5, 2018 (prior to the first nudge launch in Vanguard clinics), CW compliance for 1278 patients was mean (95% CI)-16.1% (14.1%, 18.1%). From July 3 to October 22, 2019 (after BE-EHR module launch at all five clinics), CW compliance for 680 patients was 21.2% (18.1%, 24.3%). CONCLUSIONS: The BE-EHR module shows promise for promoting the AGS CW guideline and improving diabetes management in older adults. A randomized controlled trial will commence to test the effectiveness of the intervention across 66 NYULH clinics. NIH TRIAL REGISTRY NUMBER: NCT03409523.

RESUMO

OBJECTIVE: The current study examined the interactive effect of type 2 diabetes and Alzheimer disease (AD) risk factors on the rate of functional decline in cognitively normal participants from the Alzheimer's Disease Neuroimaging Initiative. METHODS: Participants underwent annual assessments that included the Functional Activities Questionnaire, an informant-rated measure of everyday functioning. Multilevel modeling, controlling for demographic variables and ischemic risk, examined the interactive effects of diabetes status (diabetes, n=69; no diabetes, n=744) and AD risk factors in the prediction of 5-year longitudinal change in everyday functioning. One model was run for each AD risk factor, including: objectively-defined subtle cognitive decline (Obj-SCD), and genetic susceptibility [apolipoprotein E ε4 (APOE ε4) as well as cerebrospinal fluid ß-amyloid (Aß), total tau (tau), and hyperphosphorylated tau (p-tau). RESULTS: The 3-way diabetes×AD risk factor×time interaction predicted increased rates of functional decline in models that examined Obj-SCD, APOE ε4, tau, and p-tau positivity, but not Aß positivity. CONCLUSIONS: Participants with both diabetes and at least 1 AD risk factor (ie, Obj-SCD, APOE ε4, tau, and p-tau positivity) demonstrated faster functional decline compared with those without both risk factors (diabetes or AD). These findings have implications for early identification of, and perhaps earlier intervention for, diabetic individuals at risk for future functional difficulty.
