RESUMO

BACKGROUND: Despite highly effective HIV preexposure prophylaxis (PrEP) options, no options provide on-demand, nonsystemic, behaviorally congruent PrEP that many desire. A tenofovir-medicated rectal douche before receptive anal intercourse may provide this option. METHODS: Three tenofovir rectal douches-220 mg iso-osmolar product A, 660 mg iso-osmolar product B, and 660 mg hypo-osmolar product C-were studied in 21 HIV-negative men who have sex with men. We sampled blood and colorectal tissue to assess safety, acceptability, pharmacokinetics, and pharmacodynamics. RESULTS: The douches had high acceptability without toxicity. Median plasma tenofovir peak concentrations for all products were several-fold below trough concentrations associated with oral tenofovir disoproxil fumarate (TDF). Median colon tissue mucosal mononuclear cell (MMC) tenofovir-diphosphate concentrations exceeded target concentrations from 1 hour through 3 to 7 days after dosing. For 6-7 days after a single product C dose, MMC tenofovir-diphosphate exceeded concentrations expected with steady-state oral TDF 300 mg on-demand 2-1-1 dosing. Compared to predrug baseline, HIV replication after ex vivo colon tissue HIV challenge demonstrated a concentration-response relationship with 1.9 log10 maximal effect. CONCLUSIONS: All 3 tenofovir douches achieved tissue tenofovir-diphosphate concentrations and colorectal antiviral effect exceeding oral TDF and with lower systemic tenofovir. Tenofovir douches may provide a single-dose, on-demand, behaviorally congruent PrEP option, and warrant continued development. Clinical Trials Registration . NCT02750540.

RESUMO

HPTN 069/ACTG 5305 was designed to evaluate potential new PrEP regimens that included maraviroc, tenofovir disoproxil fumarate, and/or emtricitabine. The current analyses assessed antiretroviral (ARV) plasma concentrations in relation to sexual behavior in 224 cisgender men who have sex with men and 2 transgender women at risk for HIV. Poisson generalized estimating equations (GEE) regression were used to test for associations between self-reported sexual behavior, sociodemographic, behavioral variables, and study drug levels The median (IQR) age was 30 [25, 37] years old; 48.2% had completed college; 27.4% were Black and 21.7% Latino. At weeks 24 and 48, one third of participants reported condomless anal sex (CAS) in the prior month with more than one partner. CAS was associated with daily ARV drug use (χ2 = 12.64, p = 0.002). Older individuals and those with greater education were more likely to ingest ARV drugs daily (χ2 = 9.36, p = 0.009 and χ2 = 8.63, p = 0.013, respectively), while neither race nor ethnicity was associated with daily ARV drug use. Participants who reported recent condomless anal sex and/or advanced education had higher rates of daily ARV drug use. These data support the need for ongoing adherence counseling in clinical trials of new PrEP modalities.

RESUMO

This study describes the acceptability of a rectal microbicide gel formulation using dapivirine (DPV) among men and women from two countries (United States and Thailand) participating in the Microbicide Trials Network-026 trial. We evaluated participants' acceptability of a rectal DPV/placebo gel as part of a Phase I trial (N = 26; 18 male, 8 female). Participants reported favorable acceptability of the study gel, with most participants reporting that they liked the gel the same (n = 14; 53.8%) or more (n = 11; 42.4%) than when they started the trial. Over half of participants noted that they would prefer the gel over condoms (n = 13; 50%) or that they liked condoms and the gel equally (n = 8; 30.8%). Side effects across products included leakage (n = 8; 30.8%), diarrhea (n = 4; 15.4%), or soiling (n = 1; 3.8%). The high acceptability of a rectal gel underscores its promise as a short-acting biomedical prevention, warranting future research for HIV prevention.Trial Registration: NCT03239483.


RESUMEN: Este estudio describe la aceptabilidad de un microbicida rectal (RM) con dapivirina (DPV) formulado como un gel por hombres y mujeres de dos países (Estados Unidos y Tailandia) que participaron como parte del Microbicide Trials Network (MTN)-026. Evaluamos la aceptabilidad de un gel rectal de DPV y un placebo como parte de un estudio de Fase I (N = 26; 18 hombres, 8 mujeres). Los participants informaron una aceptabilidad favorable sobre el gel del estudio; la mayoría de los participantes informaron que les gustó el gel igual (n = 14; 53.8%) o más (n = 11; 42.4%) que cuando comenzaron el estudio. Más de la mitad de los participantes señalaron que preferirían el gel sobre los condones (n = 13; 50%) o que les gustaban los condones y el gel por igual (n = 8; 30,8%). Los efectos de los productos incluyeron fugas (n = 8; 30,8%), diarrea (n = 4; 15,4%) o ensuciamiento (n = 1; 3,8%). La alta aceptabilidad de un gel rectal enfatiza su promesa para la prevención biomédica de acción corta y justifica futuras investigaciones para la prevención del VIH.

RESUMO

AIM: Using an integrated model of health literacy, we discuss the importance of health literacy among foreign domestic workers in the provision of informal caregiving during outbreaks of communicable diseases. COVID-19 pandemic is used as an example. BACKGROUND: Adequate health literacy in the population is known to be important for the prevention of communicable diseases. Foreign domestic workers, a group of marginalised caregivers in private households, are generally presumed to have limited health literacy because of numerous socio-cultural disadvantages. To date, there is limited evidence that these informal healthcare providers receive support from community-based nurses. DESIGN: A discursive paper. CONCLUSION: Foreign domestic workers, with varying levels of health literacy, may be viewed either as a resource to break the chain of infection or as a potential reservoir of communicable diseases in the community. Meanwhile, restrictions imposed in response to diseases transmissions (e.g. stay-at-home measures for COVID-19) may directly exacerbate the social support received by these foreign domestic works and their ability to access health-related information. There are also concerns about their ability to appraise and evaluate information related to communicable diseases at a time when fake news and misinformation are being disseminated through social media. Language and cultural barriers are important issues that need to be addressed to ensure that foreign domestic workers are in a position to follow public health recommendations. RELEVANCE TO CLINICAL PRACTICE: Nurses hold an important position in empowering foreign domestic workers with adequate health literacy, by engaging groups of foreign domestic workers in the community and their consulates in planning educational programmes and effectively disseminating information. At a time of global pandemic, an assessment of the health literacy levels of foreign domestic workers in places like Hong Kong is urgently required.

RESUMO

BACKGROUND: Global societal changes, such as increasing longevity and a shortage of family caregivers, have given rise to a popular worldwide trend of employing live-in migrant care workers (MCWs) to provide homecare for older people. However, the emotional labor and morality inherent in their interactions with older people are largely unknown. The aim of the present study is to understand the corporeal experiences of live-in migrant care workers in the delivery of emotional labor as seen in their interactions with older people by: (1) describing the ways by which they manage emotional displays with older people; and (2) exploring their morality as enacted through emotional labor. METHODS: We performed a secondary analysis drawing on feminist phenomenology to thematically analyze data from interviews with 11 female MCWs. Follow-up interviews were conducted with 10 participants. The participants had two to 15 years of experience in caring for older people in their homes in Hong Kong. RESULTS: Performing emotional labor by suppressing and inducing emotions is morally demanding for live-in MCWs, who experience socio-culturally oppressive relationships. However, developing genuine emotions in their relationships with older people prompted the MCWs to protect the interests of older people. Through demonstrating both fake and genuine emotions, emotional labor was a tactic that live-in MCWs demonstrated to interact morally with older people. CONCLUSIONS: Emotional labor allowed live-in MCWs to avoid conflict with older people, and to further protect their own welfare and that of others. This study highlights the significance of empowering live-in MCWs by training them in ways that will help them to adapt to working conditions where they will encounter diverse customs and older people who will develop an increasing dependence on them. Thus, there is a need to develop culturally appropriate interventions to empower live-in MCWs to deliver emotional labor in a moral manner.

RESUMO

Background: Human immunodeficiency virus (HIV) disproportionately affects men who have sex with men (MSM) and transgender women (TGW). Safe and acceptable topical HIV prevention methods that target the rectum are needed. Methods: MTN-017 was a phase 2, 3-period, randomized sequence, open-label, expanded safety and acceptability crossover study comparing rectally applied reduced-glycerin (RG) 1% tenofovir (TFV) and oral emtricitabine/TFV disoproxil fumarate (FTC/TDF). In each 8-week study period participants were randomized to RG-TFV rectal gel daily, or RG-TFV rectal gel before and after receptive anal intercourse (RAI; or at least twice weekly in the event of no RAI), or daily oral FTC/TDF. Results: MSM and TGW (n = 195) were enrolled from 8 sites in the United States, Thailand, Peru, and South Africa with mean age of 31.1 years (range 18-64). There were no differences in ≥grade 2 adverse event rates between daily gel (incidence rate ratio [IRR], 1.09; P = .59) or RAI gel (IRR, 0.90; P = .51) compared to FTC/TDF. High adherence (≥80% of prescribed doses assessed by unused product return and Short Message System reports) was less likely in the daily gel regimen (odds ratio [OR], 0.35; P < .001), and participants reported less likelihood of future daily gel use for HIV protection compared to FTC/TDF (OR, 0.38; P < .001). Conclusions: Rectal application of RG TFV gel was safe in MSM and TGW. Adherence and product use likelihood were similar for the intermittent gel and daily oral FTC/TDF regimens, but lower for the daily gel regimen. Clinical Trials Registration: NCT01687218.

RESUMO

OBJECTIVE: To provide an up-to-date summary of current literature on the management of adverse effects of androgen-deprivation therapy (ADT). PATIENTS AND METHODS: All relevant medical literature on men with prostate cancer treated with ADT from 2005 to 2014, and older relevant papers, were reviewed. Recent health advisory statements from the Australian government, societies and advocacy groups have been incorporated to the document. RESULTS: There are numerous adverse effects of ADT that require pro-active prevention and treatment. Ranging from cardiovascular disease, diabetes and osteoporosis, to depression, cognitive decline and sexual dysfunction, the range of adverse effects is wide. Baseline assessment, monitoring, prevention and consultation from a multidisciplinary team are important in minimising the harm from ADT. CONCLUSIONS: This review provides a series of practical recommendations to assist with managing the adverse effects of ADT.

RESUMO

INTRODUCTION: End-user perspectives are vital to the design of new biomedical HIV prevention products. Conjoint analysis can support the integration of end-user perspectives by examining their preferences of potential pre-exposure prophylaxis (PrEP) products. The Microbicides Trial Network (MTN) 035 protocol examined three placebo rectal dosage forms (insert, enema and suppository) that could deliver PrEP prior to receptive anal sex (RAS). METHODS: Between April 2019 and July 2020, we enrolled 217 HIV-negative, cisgender men who have sex with men (MSM; n = 172; 79.3%) and transgender people (n = 47; 20.7%) ages 18-35 into a randomized cross-over trial across Malawi, Peru, South Africa, Thailand and the United States. Participants used each product prior to RAS over 4-week periods. Participants completed a conjoint experiment where they selected between random profiles using seven features (dosage form, timing of use before sex, side effects, duration of protection, effectiveness, frequency of use and need for a prescription). RESULTS: Effectiveness was the strongest determinant of choice (30.4%), followed by modality (18.0%), potential side effects (17.2%), frequency of use (10.8%), duration of protection (10.4%), timing of use before sex (7.4%) and need for a prescription (5.9%). Relative utility scores indicated that the most desirable combination of attributes was a product with 95% efficacy, used 30 minutes before sex, offering a 3- to 5-day protection window, used weekly, having no side effects, in the form of an enema and available over-the-counter. CONCLUSIONS: Choice in next-generation PrEP products is highly desired by MSM and transgender people, as no one-size-fits-all approach satisfies all the preferences. MTN-035 participants weighed product features differently, recognizing the need for diverse, behaviourally congruent biomedical options that fit the needs of intended end-users.

RESUMO

AIM: The first scoping review is to map and synthesize the stressors, problems and coping strategies surrounding the health issues of migrant domestic workers. DESIGN: Scoping review using Arksey and O'Malley's five-stage framework. METHODS: Ten electronic databases were systematically searched by keywords for literature published between January 1995 and December 2019. Data were extracted into tables and collated and summarized into themes for presentation. RESULTS: Twenty-seven reports were included in the final review. Analysis revealed that stressors to health included abuse, poor health service accessibility, ongoing financial hardship despite demanding working conditions and social isolation. Physical and mental health problems were identified for which migrant domestic workers largely depended on social networks and religion to cope with stressors and health problems. Training para-professional peer leaders of migrant domestic workers by community nurses and including them in interprofessional teams is a possible way for nurses to promote their health and well-being.

RESUMO

Introduction: Coronavirus disease 2019 (COVID-19) increases rapidly and causes mortality in all groups, including children. However, the predictive risk factors of mortality among children remain inconclusive. This study aimed to analyse the predictors related to mortality among children with COVID-19. Methods: Secondary data analysis was conducted using provincial COVID-19 data from April 2020 to May 2021. We selected 6441 children under age 18 to be included in this study. Chi-square and binary logistic regression were used to evaluate the predictors of mortality in children with COVID-19. Results: This study showed that the prevalence of children who died COVID-19 was 2.7%. Age, case definition, treatment status, severity of illness, and travel history had a significant relationship with survival status in children with COVID-19. As the increasing age, the risk of death with COVID-19 will decrease [AOR=0.94; CI 95%=0.91-0.97]. Otherwise, suspected status [AOR=2.12; 95% CI=1.48-3.04], hospitalization with ventilators [AOR=22.25; 95% CI=5.73-86.42], severe illness [AOR=46.76; 95% CI=21.69-100.80], and travel history [AOR=1.78; 95% CI=1.22-2.60] were significantly related with an increased risk of death in children with COVID-19. Discussion: Severe illness in children was the strongest predictor of mortality. Disease prevention and health promotion programs are the key to preventing hospitalizations in children and decreasing the mortality rate.

RESUMO

Efforts to develop a range of HIV prevention products that can serve as behaviorally congruent viable alternatives to consistent condom use and oral pre-exposure prophylaxis (PrEP) remain crucial. MTN-035 was a randomized crossover trial seeking to evaluate the safety, acceptability, and adherence to three placebo modalities (insert, suppository, enema) prior to receptive anal intercourse (RAI). If participants had no RAI in a week, they were asked to use their assigned product without sex. We hypothesized that the modalities would be acceptable and safe for use prior to RAI, and that participants would report high adherence given their behavioral congruence with cleansing practices (e.g., douches and/or enemas) and their existing use to deliver medications (e.g., suppositories; fast-dissolving inserts) via the rectum. Participants (N = 217) were sexual and gender minorities enrolled in five different countries (Malawi, Peru, South Africa, Thailand, and the United States of America). Mean age was 24.9 years (range 18-35 years). 204 adverse events were reported by 98 participants (45.2%); 37 (18.1%) were deemed related to the study products. The proportion of participants reporting "high acceptability" was 72% (95%CI: 65% - 78%) for inserts, 66% (95%CI: 59% - 73%) for suppositories, and 73% (95%CI: 66% - 79%) for enemas. The proportion of participants reporting fully adherent per protocol (i.e., at least one use per week) was 75% (95%CI: 69% - 81%) for inserts, 74% (95%CI: 68% - 80%) for suppositories, and 83% (95%CI: 77% - 88%) for enemas. Participants fully adherent per RAI-act was similar among the three products: insert (n = 99; 58.9%), suppository (n = 101; 58.0%) and enema (n = 107; 58.8%). The efficacy and effectiveness of emerging HIV prevention drug depends on safe and acceptable delivery modalities that are easy to use consistently. Our findings demonstrate the safety and acceptability of, and adherence to, enemas, inserts, and suppositories as potential modalities through which to deliver a rectal microbicide.

RESUMO

Many have asked "what is the benefit of the DHP over the current situation?" We believe that the responsiveness of research to community health needs and the balance of research and teaching outcomes in academic institutions can be improved, and stronger incentives to integrate research outcomes into clinical practice can be provided. The DHP is thus set up differently to a clinical research centre. The aim of our DHP is to improve health outcomes by means of coordinated excellence in teaching, research and clinical care. Technical efficiencies and excellence in care mean that financial efficiencies will occur. Joint clinical, research and teaching initiatives are underway, and plans are being developed to teach future clinical staff the science of clinician-directed, rational use of medical resources. These include pathology, imaging services, pharmaceuticals and patient referrals, assisted by published expert guidelines. There are significant administrative and personnel issues to surmount, but planning for integration has begun, and plans for turning research outcomes into clinical care plans are already emerging.

RESUMO

Multipurpose prevention technologies (MPT) have been increasingly researched for their dual-purpose preventative properties against HIV and other STIs. The acceptability of PC-1005, a topical MPT candidate, was explored among men and women participating in the MTN-037 Phase I trial at two U.S. sites (Pittsburgh, PA, and Birmingham, AL). We triangulated quantitative and qualitative assessments of the acceptability of three volumes (4 mL, 16 mL, 32 mL) of PC-1005 administered rectally (N = 12; 6 males, 6 females). Participants rated overall gel acceptability on a scale of 1-10, with a median of 7.17 (SD = 2.04) and had positive feelings about all three dose volumes, citing them to be very comfortable or comfortable (dose 1 = 91.7%; dose 2 = 91.7%; dose 3 = 83.3%). High acceptability of and comfort with all three dose volumes shows promise for PC-1005 as an MPT to prevent HIV and STIs, warranting future clinical development.

RESUMO

Dapivirine (DPV), formulated as vaginal ring, demonstrated HIV risk reduction. MTN-026 explored DPV, formulated as rectal gel, for safety, pharmacokinetics (PK), and acceptability. HIV-uninfected men and women aged 18-45 years were enrolled at United States and Thailand sites and randomized 2:1 to receive DPV 0.05% or placebo gel via rectal applicator. A single-dose phase was followed by seven observed daily doses. Plasma and fluid and tissue from both rectum and cervix were collected at baseline and after the final dose over 72 h for PK, ex-vivo HIV-1 biopsy challenge, histology, and flow cytometry. Twenty-eight participants were randomized; 2 terminated early; 9 were female and 19 male; 12 were white, 11 Asian, 4 black, and 1 other race/ethnicity. Mean age was 28.5 and 34.2 years in the DPV and placebo arms, respectively. Thirty adverse events occurred (all Grade 1 or 2, except one unrelated Grade 3) without study arm differences. DPV rectal tissue concentrations [median (interquartile range)] 0.5-1 and 2 h after a single dose were 256 ng/g [below the lower limit of quantification (BLQ)-666] and BLQ (BLQ-600), respectively, then BLQ (BLQ-BLQ) from 24 to 72 h; concentrations following multiple doses were similar. The largest median DPV plasma concentrations were 0.33 ng/mL (0.15-0.48) after one dose and 0.40 (0.33-0.49) after seven doses. The DPV rectal gel was acceptable and without safety concerns. While DPV plasma concentrations were similar to the vaginal ring, rectal tissue concentrations were well below vaginal ring tissue concentrations, suggesting need for reformulation. Clinical trial number: NCT03239483.

RESUMO

We triangulated quantitative and qualitative assessments to evaluate participants' acceptability of 0.05% dapivirine rectal microbicide (RM) gel administered via two separate modalities (a rectal applicator and an artificial phallus for use as a coital simulation device) as part of a Phase I trial (N = 14) among men who have sex with men (MSM) randomized using a 1:1 ratio. Overall, participants reported favorable acceptability of the gel (n = 11; 78.6%), the same or more at the end of the study compared to when they started the study. Additionally, when discussing their preferred administration modality, they noted that both methods had positive qualities but also potential areas of improvement. Our findings underscore the need to create multiple delivery methods for a future microbicide gel (i.e., with and without the need for an applicator) and highlight the importance of offering MSM choices in how biomedical HIV prevention strategies are delivered.

RESUMO

Gonadal steroids modulate the effects of GH, with oestrogens attenuating and androgens augmenting GH action. Whether these divergent effects influence the clinical manifestation, management and prognosis of acromegaly have not been carefully reviewed. This review examines whether there is a gender difference in epidemiology, presentation, quality of life (QoL), morbidity, treatments and mortality of acromegaly. Acromegaly is more common in women who present at an older age with longer diagnostic delay. At presentation, women have a higher GH relative to IGF-1 level than men. QoL is more adversely affected in women both before and after treatment. Prevalence of hypertension and diabetes are greater in women than in men with acromegaly. Treatment outcomes with SSAs are comparable between sexes, but women may require a higher dose of pegvisomant for equivalent response. Mortality in untreated acromegaly is more profoundly affected in women; however, improved treatments in recent decades have resulted in normalisation of standard mortality ratios in both sexes. We conclude that gender does matter in the management of acromegaly, with women presenting later in life, with greater diagnostic delay, higher prevalence of comorbidities and experiencing worse QoL.

RESUMO

Advances in clinical chemistry, molecular biology and information technology have brought about major changes in the field of endocrinology. The future practice of endocrinology will be influenced by secular health trends, consumer expectations and the globalisation of health. Pharmacotherapy will remain the backbone of endocrine therapy led by developments in drug delivery technology, pharmacogenomics, combinatorial chemistry and paracrinology. The endocrine-related consequences of obesity and ageing will be major health problems, demand for anti-obesity and anti-ageing treatments will escalate. There will be increased blurring between endocrine disease and non-disease. The future clinical endocrinologist must continue to practice evidence-based medicine to improve the treatment of genuine endocrinopathies.

RESUMO

In March 2013, the Acromegaly Consensus Group met to revise and update guidelines for the medical treatment of acromegaly. The meeting comprised experts skilled in the medical management of acromegaly. The group considered treatment goals covering biochemical, clinical and tumour volume outcomes, and the place in guidelines of somatostatin receptor ligands, growth hormone receptor antagonists and dopamine agonists, and alternative modalities for treatment including combination therapy and novel treatments. This document represents the conclusions of the workshop consensus.
