Background: Although sexual activity and function decline in older women living with HIV, positive dimensions of sexual health, such as satisfaction, are relatively unexplored. We evaluated the prevalence of sexual satisfaction for midlife women with HIV and assessed its relation to women's physical, mental, and sociostructural experiences., Setting: We studied women in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) over 3 survey waves (2013-2018)., Methods: We included women living with HIV aged ≥45 years who reported ever having consensual sex. Sexual satisfaction was assessed using an item from the Sexual Satisfaction Scale for Women and was dichotomized into satisfactory ("completely/very/reasonably satisfactory") and not satisfactory ("not very/not at all satisfactory"). Probable depression was based on CES-D ≥10. Multivariable logistic regression and fixed effects models determined correlates of sexual satisfaction. Reasons for sexual inactivity and alternate forms of sexual expression were also explored., Results: Among 508 midlife women, 61% were satisfied with their sexual lives at baseline. Women with probable depression had lower odds of sexual satisfaction than those without (aOR: 0.44; 95% CI: 0.27 to 0.71) and worsening depressive symptoms over time were associated with poorer sexual satisfaction ( P = 0.001). Increased sexual activity was associated with higher sexual satisfaction (aOR: 2.75; 95% CI: 1.54 to 4.91); however, 51% of women reporting sexual satisfaction were sexually inactive. Sexually inactive women engaged in alternate forms of sexual expression such as self-pleasure (37%) and intimate relationships without sex (13%)., Conclusion: Midlife women with HIV have high rates of sexual satisfaction, even in the absence of sexual activity. Depressive symptoms were closely associated with sexual dissatisfaction, alerting providers to the importance of screening for depression and sexual health together., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: Patterns of vitamin D intake are relatively unexplored among women living with HIV, despite its importance for women's health. We compared vitamin D dietary and supplement intakes in women with HIV and population-based national controls and investigated barriers to intake., Methods: In this case-control study, women with HIV in the Children and Women: AntiRetrovirals and Markers of Aging (CARMA) cohort were matched with Canadian Multicentre Osteoporosis Study (CaMos) controls. Participants were queried for vitamin D in dairy consumption, supplementation/dosage, and sociodemographic variables. We assessed barriers to supplementation and factors associated with dietary intake by regression modelling., Results: Ninety-five women living with HIV were age-matched to 284 controls. Women with HIV had lower income and bone mineral density and were more likely to smoke, take multiple medications and be non-white. Vitamin D dietary intake was lower in women living with HIV versus controls [0.76 vs. 1.79 μg/day; adjusted odds ratio (aOR) for greater than or equal to median intake 0.29 (0.12-0.61), p = 0.002], but any supplementation was higher [62.2% vs. 44.7%; aOR = 3.44 (95% CI: 1.16-11.00), p = 0.03]. Total vitamin D intake was similar between groups. Smoking was associated with no supplementation; non-white ethnicity and low income were related to lower dietary intake., Conclusions: Women living with HIV showed lower dietary vitamin D intake but higher supplementation rates, suggesting that care providers are promoting supplementation. Women living with HIV who smoke, have low incomes and are non-white may particularly benefit from targeted efforts to improve vitamin D intake., (© 2023 British HIV Association.)

Early menopause (<45 years) has significant impacts on bone, cardiovascular, and cognitive health. Several studies have suggested earlier menopause for women living with HIV; however, the current literature is limited by reliance on self-report data. We determined age at menopause in women living with HIV and socio-demographically similar HIV-negative women based on both self-report of menopause status (no menses for ≥12 months) and biochemical confirmation (defined as above plus follicle-stimulating hormone level ≥ 25 IU/mL). Multivariable median regression models assessed factors associated with menopause age, controlling for relevant confounders. Overall, 91 women living with HIV and 98 HIV-negative women were categorized as menopausal by self-report, compared to 83 and 92 by biochemical confirmation. Age at menopause did not differ significantly between groups, whether based on self-report (median [IQR]: 49.0 [45.3 to 53.0] vs. 50.0 [46.0 to 53.0] years; p = 0.28) or biochemical confirmation (50.0 [46.0 to 53.0] vs. 51.0 [46.0 to 53.0] years; p = 0.54). In the multivariable model, no HIV-related or psychosocial variables were associated with earlier age at menopause (all p > 0.05). Overall, HIV status per se was not statistically associated with an earlier age at menopause, emphasizing the importance of comparing socio-demographically similar women in reproductive health and HIV research.

Objectives: People living with HIV experience numerous endocrine abnormalities and psychosocial stressors. However, interactions between HIV, cortisol levels, and health outcomes have not been well described among people living with HIV on effective therapy. Furthermore, methods for measuring cortisol are disparate across studies. We describe the literature reporting cortisol levels in people living with HIV, describe methods to measure cortisol, and explore how this relates to health outcomes., Methods: We searched the PubMed database for articles published in the past 20 years regarding HIV and cortisol with ≥50% of participants on antiretroviral therapies. Articles included observational, case-control, cross-sectional, and randomized controlled trials analyzing cortisol by any method. Studies were excluded if abnormal cortisol was due to medications or other infections. Variables were extracted from selected studies and their quality was assessed using the Newcastle-Ottawa Scale., Results: In total, 19 articles were selected and included, covering the prevalence of abnormal cortisol (n = 4), exercise (n = 4), metabolic syndrome and/or cardiovascular disease (n = 2), mental health and cognition (n = 9), and sex/gender (n = 6). Cortisol was measured in serum (n = 7), saliva (n = 8), urine (n = 2), and hair (n = 3) specimens. Comparisons between people with and without HIV were inconsistent, with some evidence that people with HIV have increased rates of hypocortisolism. Depression and cognitive decline may be associated with cortisol excess, whereas anxiety and metabolic disease may be related to low cortisol; more data are needed to confirm these relationships., Conclusions: Data on cortisol levels in the era of antiretroviral therapy remain sparse. Future studies should include controls without HIV, appropriately timed sample collection, and consideration of sex/gender and psychosocial factors., (© 2022 British HIV Association.)

Background: Increasingly, women living with HIV are entering menopause (ie, cessation of menses for ≥1 year) and experiencing midlife symptoms. Menopausal hormone therapy (MHT) is first-line therapy for bothersome hot flashes and early menopause (ie, before age 45 years); however, its use in women living with HIV is poorly described. We conducted a cross-sectional assessment of MHT uptake and barriers to use in this group., Setting: This study was conducted across 3 Canadian provinces from 2015 to 2017., Methods: Perimenopausal and postmenopausal women living with HIV (35 years or older) in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study who answered questions related to MHT use were included. Univariable/multivariable logistic regression evaluated factors associated with MHT use, adjusted for age and contraindications., Results: Among 464 women, 47.8% (222 of 464) had a first-line indication for MHT; however, only 11.8% (55 of 464) reported ever using MHT and 5.6% (26 of 464) were current users. Only 44.8% had ever discussed menopause with their care provider despite almost all women having regular HIV care (97.8%). African/Caribbean/Black women had lower unadjusted odds of MHT treatment compared with White women [odds ratio (OR) 0.42 (0.18-0.89); P = 0.034]. Those who had discussed menopause with their care provider had higher odds of treatment [OR 3.13 (1.74-5.86); P < 0.001]. In adjusted analyses, only women having had a menopause discussion remained significantly associated with MHT use [OR 2.97 (1.62-5.61); P < 0.001]., Conclusion: Women living with HIV are seldom prescribed MHT despite frequent indication. MHT uptake was associated with care provider-led menopause discussions underscoring the need for care provider education on menopause management within HIV care., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objective: Women living with HIV (WLWH) are commonly symptomatic during perimenopause and menopause (≥1 y without menstruation), however, little is known of risks for symptoms and their timing. We analyzed these unwanted experiences to inform care., Methods: WLWH (≥40 y) in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study rated midlife experiences for seven symptoms and a symptom composite (from 0 to 21). Timing was categorized into four phases: i) perimenopause (flow in the last year), ii) 1-2 years from final menstrual period (FMP), iii) 2-5 years post-FMP; and iv) >5 years post-FMP. Resilience (standardized out of 100) was assessed based on Wagnild's Resilience Scale. Univariable/multivariable mixed effects linear regression assessed correlates of symptom intensity by composite score., Results: Among 457 peri-/menopausal women mean age 54.7 (±6.6) over two time points (703 observations), 88% experienced ≥1 mild symptom; 75% were of moderate and 55% severe intensity. The most frequently reported symptoms were joint/muscle stiffness (67%), depressed mood (67%), and hot flashes (57%). After adjusting for reproductive phase, we found that women with greater resilience had fewer/lower intensity symptoms (symptom score 1.37 [2.30 to 0.44] lower; P = 0.004); those with depressive symptoms and recreational drug use (respectively) had more/higher intensity symptoms (scores 1.71 [0.61 to 2.82] [P = 0.002]; 2.89 [2.09 to 3.77] [P<0.001] higher). Symptoms were most intense in perimenopause and declined with increasing menopausal years (P = 0.03)., Conclusions: WLWH experiences a high burden of midlife symptoms, decreased by resilience and most intense during perimenopause. Unwanted experiences were linked to psychosocial and behavioral factors. These data encourage HIV providers to adopt a bio-psychosocial approach to midlife management., Competing Interests: Funding/support: This work is supported by funding from the Michael Smith Foundation of Health research, CIHR Women’s Health and Mentorship Grant, CIHR Canadian Trials Network and UBC Clinician Investigator Program.

The COVID-19 pandemic has caused millions of infections and deaths worldwide, forced schools to suspend classes, workers to work from home, many to lose their livelihoods, and countless businesses to close. Throughout this crisis, families have had to protect, comfort and care for their children, their elderly and other members. While the pandemic has greatly intensified family care responsibilities for families, unpaid care work has been a primary activity of families even in normal times. This paper estimates the future global need for caregiving, and the burden of that need that typically falls on families, especially women. It takes into account projected demographic shifts, health transitions, and economic changes in order to obtain an aggregate picture of the care need relative to the potential supply of caregiving in low-, middle- and high-income countries. This extensive margin of the future care burden, however, does not capture the weight of that burden unless the quantity and quality of care time per caregiver are taken into account. Adjusting for care time given per caregiver, the paper incorporates data from time-use surveys, illustrating this intensive margin of the care burden in three countries that have very different family and economic contexts-Ghana, Mongolia, and South Korea. Time-use surveys typically do not provide time data for paid care services, so the estimates depend only on the time intensity of family care. With this caveat, the paper estimates that the care need in 2030 would require the equivalent of one-fifth to two-fifths of the paid labor force, assuming 40 weekly workhours. Using the projected 2030 mean wage for care and social service workers to estimate the hypothetical wage bill for these unpaid caregivers if they were paid, we obtain a value equivalent to 16 to 32 percent of GDP in the three countries., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 Elsevier Ltd.

A 21-year-old, previously healthy male presented to hospital following 1 week of bilateral asymmetric ascending paralysis, odynophagia, and dysphagia. Initial magnetic resonance imaging (MRI) of the spine revealed an abnormal increased T2 signal with predominant dorsal column involvement and sparing of white matter throughout the cervical cord and extending to T5. The initial presumptive diagnosis was an acute infectious, versus inflammatory, myelitis. On reviewing the history, family members recalled a bat scratch on the left hand, sustained months prior, for which the patient did not seek or receive post-exposure prophylaxis (PEP). Rabies virus (RABV) RNA was detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR) in two saliva samples, while nuchal skin biopsy and cerebrospinal fluid (CSF) were negative. Serum was negative for RABV neutralizing antibody. Sequencing and phylogenetic analyses identified the infecting RABV as a variant associated with silver-haired bats. Following risk assessment of exposure, 67 health care workers and several family members were offered PEP., Competing Interests: The authors have nothing to disclose., (Copyright © 2020, Association of Medical Microbiology and Infectious Disease Canada (AMMI Canada).)

Background: Women living with HIV (WLWH) have higher rates of prolonged secondary amenorrhea (no flow for ≥1 year) than HIV-negative women. Both having amenorrhea and being HIV positive are associated with lower areal bone mineral density (BMD). However, their combined BMD effects remain unclear. Therefore, we investigated prolonged amenorrhea and BMD in WLWH and controls., Methods: This cross-sectional study enrolled WLWH and HIV-negative control women aged 19-68 years of similar backgrounds. We assessed BMD (Hologic; as age- and ethnicity-matched Z-scores) in the Children and women: AntiRetrovirals and Markers of Aging cohort. Participants were stratified by amenorrhea history defined as past/present lack of menses for ≥1 year at age 45 and younger and not because of surgery, breastfeeding, pregnancy, or hormonal contraception. Hip and spine Z-scores by amenorrhea/no amenorrhea used linear models with multivariable analysis for relationships within WLWH., Results: WLWH (N = 129) were similar to controls (N = 129) in age, body mass index, ethnicity, and substance use. Among WLWH, 21% experienced prolonged amenorrhea vs. 9% in controls. WLWH had significantly lower total hip (mean ± SD: -0.4 ± 0.9 vs. 0.3 ± 1.1; P < 0.001) and spine (-0.5 ± 1.3 vs. 0.2 ± 1.3; P = 0.001) Z-scores than controls. Amenorrhea was independently associated with hip (P = 0.01) but not spine (P = 0.94) BMD by multivariable linear regression. WLWH with amenorrhea had lower hip Z-scores (-0.8 ± 0.9) than those without (-0.3 ± 0.8; P = 0.01). They also had higher rates of substance use, smoking, opioid therapy, hepatitis C coinfection, and lower CD4 nadir., Conclusions: WLWH had higher rates of prolonged amenorrhea and lower BMD than controls. WLWH with amenorrhea experienced lower hip BMD Z-scores than those without. Prolonged amenorrhea is an added osteoporosis risk in WLWH.

The floor plate of the developing midbrain gives rise to dopaminergic (DA) neurons, an important class of cells involved in Parkinson's disease (PD). Neural progenitors of the midbrain floor plate utilize key genes in transcriptional networks to drive dopamine neurogenesis. Identifying factors that promote dopaminergic neuron transcriptional networks can provide insight into strategies for therapies in PD. Using the chick embryo, we developed a quantitative PCR (qPCR) based method to assess the potential of a candidate factor to drive DA neuron gene expression, including the basic helix-loop-helix transcription factor Nato3 (Ferd3l). We then showed that overexpression of Nato3 in the developing chick mesencephalon produces a regionally dependent increase in genes associated with the DA neurogenesis, (such as Foxa2, Lmx1b and Shh) as well as DA neuron genes Nurr1 (an immature DA neuron marker) and mRNA expression of tyrosine hydroxylase (TH, a mature DA neuron marker). Interestingly, our data also showed that Nato3 is a potent regulator of Lmx1b by its broad induction of Lmx1b expression in neural progenitors of multiple regions of the CNS, including the midbrain and spinal cord. These data introduce a new, in vivo approach to identifying a gene that can drive DA transcriptional networks and provide the new insight that Nato3 can drive expression of key DA neuron genes, including Lmx1b, in neural progenitors., (Copyright © 2019 IBRO.

Objective: There is conflicting literature to support a link between HIV and amenorrhea. Here, we conduct a meta-analysis to summarize the results from landmark studies in this area and shed light on this important clinical association., Methods: Using a search of Ovid Medline and Embase, a total of 322 articles were screened for controlled matched observational studies of amenorrhea in premenopausal women living with HIV (WLWH). For inclusion, amenorrhea was defined as absence of menses for 3 months or longer. The meta-analysis used a random-effects model with an I2 calculated to assess heterogeneity., Results: Six studies from 1996 to 2010 were included in our analysis for a total of 8925 women (6570 WLWH). There was a significant association between HIV status and amenorrhea (OR 1.68, P value 0.0001) without evidence of heterogeneity (I2: 0.0%). In the majority of studies, there was no significant difference in substance use, smoking, or socioeconomic status between WLWH and controls. Additionally, in the majority of studies, amenorrhea in the setting of low BMI was significantly more frequent in WLWH than controls., Conclusion: This meta-analysis provides a large population assessment of amenorrhea in HIV to suggest increased prevalence of menstrual disturbances in WLWH. It lends evidence suggestive that this relation is independent of substance use and socioeconomic status, but may be related to low BMI. Our findings reinforce the importance of routine assessment of reproductive health and time of last menstrual period as part of the health assessment of women, especially those living with HIV.

Purpose: To investigate the efficacy of plasma rich in growth factors (PRGF; BTI Biotechnology Institute, San Antonio, Spain) for the treatment of alveolar osteitis compared with a positive control (Alvogyl; Septodont, Maidstone, Kent, UK)., Materials and Methods: This single-center, single-blinded, randomized, 2-treatment, parallel study was conducted in a UK dental hospital. All healthy adults who presented with alveolar osteitis after tooth extraction over a 3-month period were invited to participate. Each socket was randomized and treated with 1 of 2 treatment modalities, a test treatment (PRGF) or a positive control (Alvogyl). After treatment, patients were reviewed at 3 and 7 days by a second clinician blinded to the treatment given. Outcome measures included pain, exposed bone, inflammation, halitosis, dysgeusia, and quality-of-life assessment., Results: Thirty-eight patients with data from 44 sockets (22 in the PRGF group and 22 in the Alvogyl group) were analyzed. The PRGF group showed significantly faster bone coverage and significantly decreased inflammation and halitosis (P < .05) compared with the control group receiving Alvogyl. There was no significant difference for pain, quality-of-life measures, or dysgeusia between groups., Conclusion: PRGF predictably treated alveolar osteitis after tooth extraction compared with the conventional standard treatment of Alvogyl, which has been used for many years. PRGF could be considered an alternative treatment for alveolar osteitis and indeed appears to have considerable advantages over Alvogyl., (Copyright © 2018 American Association of Oral and Maxillofacial Surgeons.

Although the mitogen-activated protein kinase (MAPK) phosphatase, DUSP1, mediates dexamethasone-induced repression of MAPKs, 14 of 46 interleukin-1β (IL1B)-induced mRNAs were significantly enhanced by DUSP1 overexpression in pulmonary A549 cells. These include the interferon regulatory factor, IRF1, and the chemokine, CXCL10. Of these, DUSP1-enhanced mRNAs, 10 including CXCL10, were IRF1-dependent. MAPK inhibitors and DUSP1 overexpression prolonged IRF1 expression by elevating transcription and increasing IRF1 mRNA and protein stability. Conversely, DUSP1 silencing increased IL1B-induced MAPK phosphorylation while significantly reducing IRF1 protein expression at 4 h. This confirms a regulatory network whereby DUSP1 switches off MAPKs to maintain IRF1 expression. There was no repression of IRF1 expression by dexamethasone in primary human bronchial epithelial cells, and in A549 cells IL1B-induced IRF1 protein was only modestly and transiently repressed. Although dexamethasone did not repress IL1B-induced IRF1 protein expression at 4-6 h, silencing of IL1B plus dexamethasone-induced DUSP1 significantly reduced IRF1 expression. IL1B-induced expression of CXCL10 was largely insensitive to dexamethasone, whereas other DUSP1-enhanced, IRF1-dependent mRNAs showed various degrees of repression. With IL1B plus dexamethasone, CXCL10 expression was also IRF1-dependent, and expression was reduced by DUSP1 silencing. Thus, IL1B plus dexamethasone-induced DUSP1 maintains expression of IRF1 and the IRF1-dependent gene, CXCL10. This is supported by chromatin immunoprecipitation showing IRF1 recruitment to be essentially unaffected by dexamethasone at the CXCL10 promoter or at the promoters of more highly repressed IRF1-dependent genes. Since IRF1-dependent genes, such as CXCL10, are central to host defense, these data may help explain the reduced effectiveness of glucocorticoids during asthma exacerbations., (© 2016 by The American Society for Biochemistry and Molecular Biology, Inc.)

Glucocorticoids act on the glucocorticoid receptor (NR3C1) to repress inflammatory gene expression. This is central to their anti-inflammatory effectiveness and rational improvements in therapeutic index depend on understanding the mechanism. Human pulmonary epithelial A549 cells were used to study the role of the mitogen-activated protein kinase (MAPK) phosphatase, dual-specificity phosphatase 1 (DUSP1), in the dexamethasone repression of 11 inflammatory genes induced, in a MAPK-dependent manner, by interleukin-1β (IL1B). Adenoviral over-expression of DUSP1 inactivated MAPK pathways and reduced expression of all 11 inflammatory genes. IL1B rapidly induced DUSP1 expression and RNA silencing revealed a transient role in feedback inhibition of MAPKs and inflammatory gene expression. With dexamethasone, which induced DUSP1 expression, plus IL1B (co-treatment), DUSP1 expression was further enhanced. At 1 h, this was responsible for the dexamethasone inhibition of IL1B-induced MAPK activation and CXCL1 and CXCL2 mRNA expression, with a similar trend for CSF2. Whereas, CCL20 mRNA was not repressed by dexamethasone at 1 h, repression of CCL2, CXCL3, IL6, and IL8 was unaffected, and PTGS2 repression was partially affected by DUSP1 knockdown. At later times, dexamethasone repression of MAPKs was unaffected by DUSP1 silencing. Likewise, 6 h post-IL1B, dexamethasone repression of all 11 mRNAs was essentially unaffected by DUSP1 knockdown. Qualitatively similar data were obtained for CSF2, CXCL1, IL6, and IL8 release. Thus, despite general roles in feedback inhibition, DUSP1 plays a transient, often partial, role in the dexamethasone-dependent repression of certain inflammatory genes. Therefore this also illustrates key roles for DUSP1-independent effectors in mediating glucocorticoid-dependent repression.

In asthma and chronic obstructive pulmonary disease, activation of G(q)-protein-coupled receptors causes bronchoconstriction. In each case, the management of moderate-to-severe disease uses inhaled corticosteroid (glucocorticoid)/long-acting β(2)-adrenoceptor agonist (LABA) combination therapies, which are more efficacious than either monotherapy alone. In primary human airway smooth muscle cells, glucocorticoid/LABA combinations synergistically induce the expression of regulator of G-protein signaling 2 (RGS2), a GTPase-activating protein that attenuates G(q) signaling. Functionally, RGS2 reduced intracellular free calcium flux elicited by histamine, methacholine, leukotrienes, and other spasmogens. Furthermore, protection against spasmogen-increased intracellular free calcium, following treatment for 6 h with LABA plus corticosteroid, was dependent on RGS2. Finally, Rgs2-deficient mice revealed enhanced bronchoconstriction to spasmogens and an absence of LABA-induced bronchoprotection. These data identify RGS2 gene expression as a genomic mechanism of bronchoprotection that is induced by glucocorticoids plus LABAs in human airway smooth muscle and provide a rational explanation for the clinical efficacy of inhaled corticosteroid (glucocorticoid)/LABA combinations in obstructive airways diseases.
