BACKGROUND: The ongoing global crisis of Higher Education (HE) institutions during the post-COVID-19 pandemic period has increased the likelihood of enduring psychological stressors for staff. This study aimed to identify factors associated with job insecurity, burnout, psychological distress and coping amongst staff working at HE institutions globally. METHODS: An anonymous cross-sectional study was conducted in 2023 with staff at HE institutions across 16 countries. Job insecurity was measured using the Job Insecurity Scale (JIS), burnout using the Perceived Burnout measure question, psychological distress using the Kessler Psychological Distress Scale (K10), and coping using the Brief Resilient Coping Scale. Multivariable logistic regression with a stepwise variable selection method was used to identify associations. RESULTS: A total of 2,353 staff participated; the mean age (± SD) was 43(± 10) years and 61% were females. Most staff (85%) did not feel job insecurity, one-third (29%) perceived burnout in their jobs, more than two-thirds (73%) experienced moderate to very high levels of psychological distress, and more than half (58%) exhibited medium to high resilient coping. Perceived job insecurity was associated with staff working part-time [Adjusted Odds Ratio 1.53 (95% Confidence Intervals 1.15-2.02)], having an academic appointment [2.45 (1.78-3.27)], having multiple co-morbidities [1.86 (1.41-2.48)], perceived burnout [1.99 (1.54-2.56)] and moderate to very high level of psychological distress [1.68 (1.18-2.39)]. Perceived burnout was associated with being female [1.35 (1.12-1.63)], having multiple co-morbidities [1.53 (1.20-1.97)], perceived job insecurity [1.99 (1.55-2.57)], and moderate to very high levels of psychological distress [3.23 (2.42-4.30)]. Staff with multiple co-morbidities [1.46 (1.11-1.92)], mental health issues [2.73 (1.79-4.15)], perceived job insecurity [1.61 (1.13-2.30)], and perceived burnout [3.22 (2.41-4.31)] were associated with moderate to very high levels of psychological distress. Staff who perceived their mental health as good to excellent [3.36 (2.69-4.19)] were more likely to have medium to high resilient coping. CONCLUSIONS: Factors identified in this study should be considered in reviewing and updating current support strategies for staff at HE institutions across all countries to reduce stress and burnout and improve wellbeing.

BACKGROUND: The transition of Australia's National Cervical Screening Program from cytology to a molecular test for human papillomavirus (HPV) (locally referred to as the 'Renewal'), including a longer five-year interval and older age at commencement, significantly impacted all sectors of program delivery. The Renewal had major implications for the roles and requirements of pathology laboratories providing services for the Program. This study aimed to understand the early impacts of the Renewal and its implementation on the pathology sector. METHODS: Semi-structured qualitative interviews were conducted with key stakeholders (N = 49) involved in the STakeholder Opinions of Renewal Implementation and Experiences Study (STORIES), 11-20 months after the program transition. A subset of interviews (N = 24) that discussed the pathology sector were analysed using inductive thematic analysis. RESULTS: Four overarching themes were identified: implementation enablers, challenges, missed opportunities, and possible improvements. Participants believed that the decision to transition to primary HPV screening was highly acceptable and evidence-based, but faced challenges due to impacts on laboratory infrastructure, resources, staffing, and finances. These challenges were compounded by unfamiliarity with new information technology (IT) systems and the new National Cancer Screening Register ('Register') not being fully functional by the date of the program transition. The limited availability of self-collection and lack of standardised fields in pathology forms were identified as missed opportunities to improve equity in the Program. To improve implementation processes, participants suggested increased pathology sector involvement in planning was needed, along with more timely and transparent communication from the Government, and clearer clinical management guidelines. CONCLUSION: The transition to primary HPV screening had a significant and multifaceted impact on the Australian pathology sector reflecting the magnitude and complexity of the Renewal. Strategies to support the pathology sector through effective change management, clear, timely, and transparent communication, as well as adequate funding sources will be critical for other countries planning to transition cervical screening programs.

Girls' menstrual experiences impact their social and educational participation, physical and psychological health. We conducted a pilot study to assess the acceptability and feasibility of a multi-component intervention intended to support menstruating girls; improve menstrual care knowledge, practices, and comfort; and increase school attendance.We conducted a pre/post evaluation of a 6-month pilot intervention in four schools (2 urban, 2 rural) in Dhaka, Bangladesh. We selected 527 schoolgirls (grades 5 to 10; aged 10 to 17 years) for a baseline survey and 528 girls at endline. The intervention included: 1) Menstrual Hygiene Management (MHM) packs- reusable cloth pads, underwear, carry bags and menstrual cycle tracking calendars, 2) education curriculum- pictorial flipcharts, puberty related-booklets, and teachers' training to deliver puberty and MHM sessions, 3) maintenance- improvements to school sanitation, provision of disposable pads in the school office, provision of chute disposal systems for disposable pads, and gender committees to promote a gender-friendly school environment and maintenance of intervention facilities. We estimated intervention uptake and intervention effect by calculating prevalence differences and 95% confidence intervals using fixed-effects logistic regression.The intervention uptake was more than 85% for most indicators; 100% reported receiving puberty education, 85% received MHM packs, and 92% received booklets. Reusable cloth pads uptake was 34% by endline compared with 0% at baseline. Knowledge about menstrual physiology and knowledge of recommended menstrual management practices significantly improved from baseline to endline. Reported improvements included more frequent changing of menstrual materials (4.2 times/day at endline vs. 3.4 times/day at baseline), increased use of recommended disposal methods (prevalence difference (PD): 8%; 95% Confidence Interval: 1, 14), and fewer staining incidents (PD: - 12%; 95% CI: - 22, - 1). More girls reported being satisfied with their menstrual materials (59% at endline vs. 46% at baseline, p < 0.005) and thought school facilities were adequate for menstrual management at endline compared to baseline (54% vs. 8%, p < 0.001). At endline, 64% girls disagreed/strongly disagreed that they felt anxious at school due to menstruation, compared to 33% at baseline (p < 0.001). Sixty-five percent girls disagreed/strongly disagreed about feeling distracted or trouble concentrating in class at endline, compared to 41% at baseline (p < 0.001). Self-reported absences decreased slightly (PD: - 8%; 95% CI: - 14, - 2).Uptake of cloth pads, improved maintenance and disposal of menstrual materials, and reduced anxiety at school suggest acceptability and feasibility of the intervention aiming to create a supportive school environment.

Data fusion aims to provide a more accurate description of a sample than any one source of data alone. At the same time, data fusion minimizes the uncertainty of the results by combining data from multiple sources. Both aim to improve the characterization of samples and might improve clinical diagnosis and prognosis. In this paper, we present an overview of the advances achieved over the last decades in data fusion approaches in the context of the medical and biomedical fields. We collected approaches for interpreting multiple sources of data in different combinations: image to image, image to biomarker, spectra to image, spectra to spectra, spectra to biomarker, and others. We found that the most prevalent combination is the image-to-image fusion and that most data fusion approaches were applied together with deep learning or machine learning methods.

BACKGROUND: The current pandemic of COVID-19 impacted the psychological wellbeing of populations globally. OBJECTIVES: We aimed to examine the extent and identify factors associated with psychological distress, fear of COVID-19 and coping. METHODS: We conducted a cross-sectional study across 17 countries during Jun-2020 to Jan-2021. Levels of psychological distress (Kessler Psychological Distress Scale), fear of COVID-19 (Fear of COVID-19 Scale), and coping (Brief Resilient Coping Scale) were assessed. RESULTS: A total of 8,559 people participated; mean age (±SD) was 33(±13) years, 64% were females and 40% self-identified as frontline workers. More than two-thirds (69%) experienced moderate-to-very high levels of psychological distress, which was 46% in Thailand and 91% in Egypt. A quarter (24%) had high levels of fear of COVID-19, which was as low as 9% in Libya and as high as 38% in Bangladesh. More than half (57%) exhibited medium to high resilient coping; the lowest prevalence (3%) was reported in Australia and the highest (72%) in Syria. Being female (AOR 1.31 [95% CIs 1.09-1.57]), perceived distress due to change of employment status (1.56 [1.29-1.90]), comorbidity with mental health conditions (3.02 [1.20-7.60]) were associated with higher levels of psychological distress and fear. Doctors had higher psychological distress (1.43 [1.04-1.97]), but low levels of fear of COVID-19 (0.55 [0.41-0.76]); nurses had medium to high resilient coping (1.30 [1.03-1.65]). CONCLUSIONS: The extent of psychological distress, fear of COVID-19 and coping varied by country; however, we identified few higher risk groups who were more vulnerable than others. There is an urgent need to prioritise health and well-being of those people through well-designed intervention that may need to be tailored to meet country specific requirements.

BACKGROUND: The COVID-19 pandemic disrupted the personal, professional and social life of Australians with some people more impacted than others. OBJECTIVES: This study aimed to identify factors associated with psychological distress, fear and coping strategies during the COVID-19 pandemic in Australia. METHODS: A cross-sectional online survey was conducted among residents in Australia, including patients, frontline health and other essential service workers, and community members during June 2020. Psychological distress was assessed using the Kessler Psychological Distress Scale (K10); level of fear was assessed using the Fear of COVID-19 Scale (FCV-19S); and coping strategies were assessed using the Brief Resilient Coping Scale (BRCS). Logistic regression was used to identify factors associated with the extent of psychological distress, level of fear and coping strategies while adjusting for potential confounders. RESULTS: Among 587 participants, the majority (391, 73.2%) were 30-59 years old and female (363, 61.8%). More than half (349, 59.5%) were born outside Australia and two-third (418, 71.5%) completed at least a Bachelor's degree. The majority (401, 71.5%) had a source of income, 243 (42.3%) self-identified as a frontline worker, and 335 (58.9%) reported financial impact due to COVID-19. Comorbidities such as pre-existing mental health conditions (AOR 3.13, 95% CIs 1.12-8.75), increased smoking (8.66, 1.08-69.1) and alcohol drinking (2.39, 1.05-5.47) over the last four weeks, high levels of fear (2.93, 1.83-4.67) and being female (1.74, 1.15-2.65) were associated with higher levels of psychological distress. Perceived distress due to change of employment status (4.14, 1.39-12.4), alcohol drinking (3.64, 1.54-8.58), providing care to known or suspected cases (3.64, 1.54-8.58), being female (1.56, 1.00-2.45), being 30-59 years old (2.29, 1.21-4.35) and having medium to high levels of psychological distress (2.90, 1.82-5.62) were associated with a higher level of fear; while healthcare service use in the last four weeks was associated with medium to high resilience. CONCLUSIONS: This study identified individuals who were at higher risk of distress and fear during the COVID-19 pandemic specifically in the State of Victoria, Australia. Specific interventions to support the mental wellbeing of these individuals should be considered in addition to the existing resources within primary healthcare settings.

BACKGROUND: Access to washroom facilities and a place to dispose of menstrual waste are prerequisites for optimal menstrual hygiene management in schools. Like other low- and middle-income countries, Bangladeshi schools lack facilities for girls to change and dispose of their menstrual absorbents. We explored existing systems for disposing of menstrual absorbent wastes in urban and rural schools of Bangladesh and assessed the feasibility and acceptability of alternative disposal options. METHODS: We explored how girls dispose of their menstrual products, identified girls' preferences and choices for a disposal system and piloted four disposal options in four different schools. We then implemented one preferred option in four additional schools. We explored girls', teachers', and janitors' perspectives and evaluated the acceptability, feasibility, and potential for sustainability of the piloted disposal system. RESULTS: Barriers to optimal menstrual hygiene management included lack of functional toilets and private locations for changing menstrual products, and limited options for disposal. Girls, teachers, and janitors preferred and ranked the chute disposal system as their first choice, because it has large capacity (765 L), is relatively durable, requires less maintenance, and will take longer time to fill. During implementation of the chute disposal system in four schools, girls, teachers, and janitors reported positive changes in toilet cleanliness and menstrual products disposal resulting from the intervention. CONCLUSIONS: The chute disposal system for menstrual products is a durable option that does not require frequent emptying or regular maintenance, and is accepted by schoolgirls and janitors alike, and can improve conditions for menstrual hygiene management in schools. However, regular supervision, motivation of girls to correctly dispose of their products, and a long-term maintenance and management plan for the system are necessary.

A fall in the positive predictive value (PPV) of cytological predictions of high-grade squamous intra-epithelial lesions (HSIL) or adenocarcinoma-in-situ (AIS) has been predicted in the post-HPV vaccination era due to the decrease in underlying prevalence of cervical lesions. Data was extracted from the Victorian Cervical Screening Registry including cervical cytology tests taken between 2000 and 2016 and any subsequent histology performed within 6 months of the cytology. PPV was calculated for each age group (<20, 20-24, 25-29, 30-34, 35-39, 40-49, 50-59, 60-69, 70+ years) and calendar year. The x2 (chi-square) test was used to identify significant trends in PPV over time in each age group in both the pre-vaccination (2000-2006) and the post-vaccination (2007-2016) periods. The overall PPV of HSIL/AIS cytology in predicting histologically confirmed high grade disease (HGD, HSIL/AIS+) was 75% and this was consistent across the different calendar years. When stratified by age group, there was a decreasing trend in the PPV in women aged <20 years (ptrend = 0.0006) and 20-24 years (ptrend = 0.0004) in the post-vaccination period but not in the pre-vaccination period (ptrend = 0.82 and ptrend = 0.73, respectively). No such decline in PPV was noted in either the pre-vaccination or the post-vaccination periods for any other age groups except the oldest women, aged 60-69 years and 70+ years. The decline in PPV of HSIL/AIS cytology in predicting HGD in age groups <20 and 20-24 years in the post-vaccination period could be an impact of the HPV vaccination.

This study demonstrates that the clinical sensitivity, specificity, and reproducibility of the novel cobas human papillomavirus (HPV) test on the cobas 6800 system for high-risk HPV types fulfills the criteria for use in population-based cervical screening. The criteria were formulated by an international consortium, using the cobas 4800 HPV test as a validated reference assay. The cobas HPV test detected over 98% of histologically confirmed cervical intraepithelial neoplasia grade 2+ (CIN2+) lesions in women age 30 years or older, with a specificity of 98.9% compared with the reference cobas 4800 test. Both the intra- and interlaboratory agreement for the cobas HPV test were 98%. The clinical performance of the cobas HPV test is comparable to those of longitudinally validated HPV assays and fulfills the criteria for its use in primary cervical screening.

OBJECTIVE: To understand factors that influence sustained adoption of water, sanitation and hygiene (WASH) technologies or behaviours. METHODS: Systematic review of the current literature. Articles were gathered from databases of peer-reviewed articles and grey literature, and screened for relevance. After exclusion, we created a descriptive map of 148 articles and analysed in-depth 44 articles that had an explicit focus on promoting or evaluating sustained adoption or programme sustainability. Twenty-two of these articles met our definition of measuring sustained adoption. RESULTS: Definitions of sustained adoption varied widely and were often inadequate, making comparison of sustained adoption across studies difficult. The time frame for measurements of sustained adoption is frequently inadequate for examination of longer-term behaviour change. CONCLUSIONS: Ideally, an evaluation should specify the project period and describe the context surrounding adoption, make measurements at multiple time points, diversify measurement methods and describe and measure a range of factors affecting sustained adoption. Additional consideration needs to be given to developing behaviour change models that emphasise factors related to sustained adoption, and how they differ from those related to initial adoption.

BACKGROUND: The objective of this study was to assess the level of knowledge of cervical cancer among Bangladeshi women and to assess their willingness to receive the human papillomavirus (HPV) vaccine. METHODS: A population-based, cross-sectional survey was conducted from July to December 2011 in one urban and one rural area of Bangladesh. A total of 2037 ever-married women, aged 14 to 64 years, were interviewed using a structured questionnaire. Data on socio-demographic characteristics and knowledge of cervical cancer were collected. Willingness to receive the HPV vaccine was assessed. Univariate analyses were completed using quantitative data collected. Multivariable logistic regression models were developed to identify factors associated with having heard of cervical cancer and the HPV vaccine. RESULTS: The majority of study participants reported to have heard of cervical cancer (urban: 89.7%, rural 93.4%; P = 0.003). The odds of having heard of cervical cancer were significantly higher in urban women aged 35-44 years (aOR: 2.92 (1.34-6.33) and rural women aged 25-34 years (aOR: 2.90 (1.24-6.73) compared to those aged less than 24 years. Very few women reported to have detailed knowledge on risk factors (urban:9.1%, rural: 8.8%) and prevention (urban: 6.4%, rural: 4.4%) of cervical cancer. In our sample, one in five urban women and one in twenty rural women heard about a vaccine that can prevent cervical cancer. Among urban women, secondary education or higher (aOR: 3.48, 95% CI: 1.67-7.25), age of 20 years and above at marriage (aOR: 2.83, 95% CI: 1.61-5.00), and high socioeconomic status (aOR: 2.25, 95% CI: 1.28-3.95) were factors associated with having heard of the HPV vaccine. Willingness to receive the HPV vaccine among study participants either for themselves (urban: 93.9%, rural: 99.4%) or for their daughters (urban: 91.8%, rural: 99.2%) was high. CONCLUSIONS: Detailed knowledge of cervical cancer among Bangladeshi women was found to be poor. Education on cervical cancer must include information on symptoms, risk factors, and preventive methods. Despite poor knowledge, the study population was willing to receive the HPV vaccine.

We conducted a randomized controlled trial to determine whether HPV self-sampling increases participation in cervical screening by never- and under-screened (not screened in past 5 years) women when compared with a reminder letter for a Pap test. Never- or under-screened Victorian women aged 30-69 years, not pregnant and with no prior hysterectomy were eligible. Within each stratum (never-screened and under-screened), we randomly allocated 7,140 women to self-sampling and 1,020 to Pap test reminders. The self-sampling kit comprised a nylon tipped flocked swab enclosed in a dry plastic tube. The primary outcome was participation, as indicated by returning a swab or undergoing a Pap test; the secondary outcome, for women in the self-sampling arm with a positive HPV test, was undergoing appropriate clinical investigation. The Roche Cobas® 4800 test was used to measure presence of HPV DNA. Participation was higher for the self-sampling arm: 20.3 versus 6.0% for never-screened women (absolute difference 14.4%, 95% CI: 12.6-16.1%, p < 0.001) and 11.5 versus 6.4% for under-screened women (difference 5.1%, 95% CI: 3.4-6.8%, p < 0.001). Of the 1,649 women who returned a swab, 45 (2.7%) were positive for HPV16/18 and 95 (5.8%) were positive for other high-risk HPV types. Within 6 months, 28 (62.2%) women positive for HPV16/18 had colposcopy as recommended and nine (20%) had cytology only. Of women positive for other high-risk HPV types, 78 (82.1%) had a Pap test as recommended. HPV self-sampling improves participation in cervical screening for never- and under-screened women and most women with HPV detected have appropriate clinical investigation.

BACKGROUND: Increasing cervical screening coverage by reaching inadequately screened groups is essential for improving the effectiveness of cervical screening programs. Offering HPV self-sampling to women who are never or under-screened can improve screening participation, however participation varies widely between settings. Information on women's experience with self-sampling and preferences for future self-sampling screening is essential for programs to optimize participation. METHODS: The survey was conducted as part of a larger trial ("iPap") investigating the effect of HPV self-sampling on participation of never and under-screened women in Victoria, Australia. Questionnaires were mailed to a) most women who participated in the self-sampling to document their experience with and preference for self-sampling in future, and b) a sample of the women who did not participate asking reasons for non-participation and suggestions for enabling participation. Reasons for not having a previous Pap test were also explored. RESULTS: About half the women who collected a self sample for the iPap trial returned the subsequent questionnaire (746/1521). Common reasons for not having cervical screening were that having Pap test performed by a doctor was embarrassing (18 %), not having the time (14 %), or that a Pap test was painful and uncomfortable (11 %). Most (94 %) found the home-based self-sampling less embarrassing, less uncomfortable (90 %) and more convenient (98%) compared with their last Pap test experience (if they had one); however, many were unsure about the test accuracy (57 %). Women who self-sampled thought the instructions were clear (98 %), it was easy to use the swab (95 %), and were generally confident that they did the test correctly (81 %). Most preferred to take the self-sample at home in the future (88 %) because it was simple and did not require a doctor's appointment. Few women (126/1946, 7 %) who did not return a self-sample in the iPap trial returned the questionnaire. Their main reason for not screening was having had a hysterectomy. CONCLUSIONS: Home-based self-sampling can overcome emotional and practical barriers to Pap test and increase participation in cervical screening despite some women's concerns about test accuracy. Mailing to eligible women and assuring women about test accuracy could further optimize participation in screening.

The proportion of Pap smears containing an endocervical component (ECC) has been declining in Australia. Given that ECC negative (ECC-) smears may be associated with reduced sensitivity, we undertook a retrospective cohort study to estimate rates of histologically confirmed high-grade cervical abnormality (HGA) and cancer in women with negative Pap smears with and without an ECC. Women 18-69 years with at least two Pap smears between 1 January 2001 and 31 December 2010 with the first smear in that period (index smear) showing no abnormality were eligible. Follow-up ended at date of the first abnormal smear, date of histological diagnosis, date of hysterectomy, date of death, or 31 December 2010, whichever came first. ECC status was treated as a time varying exposure. Follow-up was split at each smear after the index smear. Poisson regression was used to estimate adjusted incidence rates and incidence rate ratios (IRR) by ECC status. The incidence rate of histologically confirmed HGA was significantly lower following ECC- smears than after ECC+ smears (adjusted IRR: 0.69, 95%Confidence Interval (CI) 0.62-0.77), particularly at older ages (interaction between ECC status and age, p = 0.001). In contrast, the overall rate of invasive cancer was not significantly different after ECC- than after ECC+ smears (IRR: 1.27, 95%CI 0.90-1.77). In conclusion, women had a lower rate of confirmed HGA and no significant increase in the rate of invasive cervical cancer following ECC- smears. This study does not support differential (accelerated) follow-up in women with a negative smear without an endocervical component.

BACKGROUND: Organized screening based on Pap tests has substantially reduced deaths from cervical cancer in many countries, including Australia. However, the impact of the program depends upon the degree to which women participate. A new method of screening, testing for human papillomavirus (HPV) DNA to detect the virus that causes cervical cancer, has recently become available. Because women can collect their own samples for this test at home, it has the potential to overcome some of the barriers to Pap tests. The iPap trial will evaluate whether mailing an HPV self-sampling kit increases participation by never- and under-screened women within a cervical screening program. METHODS/DESIGN: The iPap trial is a parallel randomized controlled, open label, trial. Participants will be Victorian women age 30-69 years, for whom there is either no record on the Victorian Cervical Cytology Registry (VCCR) of a Pap test (never-screened) or the last recorded Pap test was between five to fifteen years ago (under-screened). Enrolment information from the Victorian Electoral Commission will be linked to the VCCR to determine the never-screened women. Variables that will be used for record linkage include full name, address and date of birth. Never- and under-screened women will be randomly allocated to either receive an invitation letter with an HPV self-sampling kit or a reminder letter to attend for a Pap test, which is standard practice for women overdue for a test in Victoria. All resources have been focus group tested. The primary outcome will be the proportion of women who participate, by returning an HPV self-sampling kit for women in the self-sampling arm, and notification of a Pap test result to the Registry for women in the Pap test arm at 3 and 6 months after mailout. The most important secondary outcome is the proportion of test-positive women who undergo further investigations at 6 and 12 months after mailout of results. DISCUSSION: The iPap trial will provide strong evidence about whether HPV self-sampling could be used in Australia to improve participation in cervical screening for never-and under-screened women.

IMPORTANCE: Whether dehydroepiandrosterone (DHEA) supplementation improves cognitive performance in older women is uncertain. Nonetheless, DHEA supplements are readily available over the counter in several countries and are potentially being used to prevent cognitive decline and dementia. OBJECTIVE: This systematic review was conducted to evaluate the effect of exogenous DHEA on cognitive performance in postmenopausal women. EVIDENCE REVIEW: Ovid MEDLINE, EMBASE, PsycINFO, Web of Science Core Collection, and the Cochrane Central Register of Controlled Trials databases were searched for studies of postmenopausal women until November 30, 2022. Eligible studies were required to be randomized clinical trials, be at least single blind, have a placebo or comparator arm and published in English. Risk of bias of the included studies was assessed by the revised Cochrane risk-of-bias tool. FINDINGS: Of the 15 articles retrieved for full-text review, four met the inclusion criteria. In all studies DHEA was administered as a 50-mg oral daily dose and all were double blind with an identical placebo. Three were placebo-controlled, crossover studies and one was a parallel-group clinical trial. The only positive outcome was limited to a 4-wk cross-over study in which DHEA statistically significantly enhanced five of six tests of visual-spatial performance compared with placebo in 24 cognitively normal postmenopausal women. Improvement in cognitive performance with DHEA treatment over placebo group was not seen in any other study. Heterogeneity of design and use of multiple measures of cognitive performance was a barrier to meta-analysis and between study comparisons. The studies were limited by high risk of bias in multiple domains. CONCLUSION AND RELEVANCE: Overall, this systematic review does not support a beneficial effect of DHEA therapy on cognitive performance in postmenopausal women.

BACKGROUND: Quantifying the benefits and harms of breast cancer screening accurately is important for planning and evaluating screening programs and for enabling women to make informed decisions about participation. However, few cohort studies have attempted to estimate benefit and harm simultaneously. AIMS: We aimed to quantify the impact of mammographic screening on breast cancer mortality and overdiagnosis using a cohort of women invited to attend Australia's national screening program, BreastScreen. METHODS: In a cohort of 41,330 women without prior breast cancer diagnosis, screening, or diagnostic procedures invited to attend BreastScreen Western Australia in 1994-1995, we estimated the cumulative risk of breast cancer mortality and breast cancer incidence (invasive and ductal carcinoma in situ) from age 50 to 85 years for attenders and non-attenders. Data were obtained by linking population-based state and national health registries. Breast cancer mortality risks were estimated from a survival analysis that accounted for competing risk of death from other causes. Breast cancer risk for unscreened women was estimated by survival analysis, while accounting for competing causes of death. For screened women, breast cancer risk was the sum of risk of being diagnosed at first screen, estimated using logistic regression, and risk of diagnosis following a negative first screen estimated from a survival analysis. RESULTS: For every 1,000 women 50 years old at first invitation to attend BreastScreen, there were 20 (95% CI 12-30) fewer breast cancer deaths and 25 (95% CI 15-35) more breast cancers diagnosed for women who attended than for non-attendees by age 85. Of the breast cancers diagnosed in screened women, 21% (95% CI 13%-27%) could be attributed to screening. DISCUSSION: The estimated ratio of benefit to harm was consistent with, but slightly less favourable to screening than most other estimates from cohort studies. CONCLUSION: Women who participate in organised screening for breast cancer in Australia have substantially lower breast cancer mortality, while some screen-detected cancers may be overdiagnosed.
RESUMEN
IMPORTANCE: The associations between endogenous dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS), and depression in older women are uncertain. However, DHEA supplements are widely available over the counter in some countries, and some people may be taking DHEA with the hope of positive mood effects. OBJECTIVE: This systematic review aimed to investigate the association between endogenous DHEA/DHEAS blood concentrations and depression/depressive symptoms in community-dwelling postmenopausal women.Evidence Review: Searches were conducted in Ovid MEDLINE, EMBASE, PsycINFO, and Web of Science databases for observational studies with at least 100 community-dwelling participants until March 9, 2022. The bibliographies of retrieved articles were manually searched. The studies published in English and meeting the inclusion criteria were included in the review. The risk of bias was assessed with the modified Hoy tool for cross-sectional designs and the Joanna Briggs Institute modified critical appraisal checklist for cohort studies. FINDINGS: Of the 30 articles retrieved for full-text review, 14 met the criteria for inclusion. Seven studies were cross-sectional, six were longitudinal, and one had both cross-sectional and longitudinal data. Five of eight cross-sectional studies found no association between DHEAS and depression, whereas three studies reported an inverse association. Similarly, most of the studies (n = 4) with longitudinal data reported no association, whereas two studies reported either an inverse association or mixed results for DHEAS and depression severity. No association between DHEA and depression was found irrespective of the study design. Heterogeneity of design was a barrier to meta-analysis and between study comparison. The majority of studies were limited by high risk of bias in at least one assessed domain. CONCLUSION AND RELEVANCE: This systematic review does not support an association between endogenous DHEA/DHEAS and depression in postmenopausal women.

OBJECTIVE: The contribution of testosterone to depression in older women is uncertain. This review was conducted to investigate the association between endogenous testosterone blood concentrations and depression in postmenopausal women. METHODS: We searched Ovid MEDLINE, EMBASE, PsycINFO, and Web of Science databases for observational studies with at least 100 community-dwelling participants. The results were categorised by study design, and the reporting of total, bioavailable and free testosterone findings is narrative. RESULTS: The search strategy retrieved 28 articles for full-text review, of which eight met the criteria for inclusion; these described 6 cross-sectional and 2 longitudinal studies. Testosterone was measured by immunoassay in all of the included studies. No association was seen between total testosterone or free testosterone and depression in either the cross-sectional or the longitudinal studies. A significant association between bioavailable testosterone and incident depressive symptoms was limited to women at least 21 years postmenopause in one study. Most of the cross-sectional studies were not representative of national populations and lacked random selection. CONCLUSIONS: This systematic review does not support an association between testosterone and depression in postmenopausal women. However, as the included studies had substantial methodological limitations, studies of community-based samples, employing validated instruments for depression and precise measurement of blood testosterone, are needed to address this knowledge gap.
