BACKGROUND
Human papillomavirus (HPV) vaccination programmes were first implemented in several countries worldwide in 2007. We did a systematic review and meta-analysis to assess the population-level consequences and herd effects after female HPV vaccination programmes, to verify whether or not the high efficacy reported in randomised controlled clinical trials are materialising in real-world situations.


METHODS
We searched the Medline and Embase databases (between Jan 1, 2007 and Feb 28, 2014) and conference abstracts for time-trend studies that analysed changes, between the pre-vaccination and post-vaccination periods, in the incidence or prevalence of at least one HPV-related endpoint: HPV infection, anogenital warts, and high-grade cervical lesions. We used random-effects models to derive pooled relative risk (RR) estimates. We stratified all analyses by age and sex. We did subgroup analyses by comparing studies according to vaccine type, vaccination coverage, and years since implementation of the vaccination programme. We assessed heterogeneity across studies using I(2) and χ(2) statistics and we did trends analysis to examine the dose-response association between HPV vaccination coverage and each study effect measure.


FINDINGS
We identified 20 eligible studies, which were all undertaken in nine high-income countries and represent more than 140 million person-years of follow-up. In countries with female vaccination coverage of at least 50%, HPV type 16 and 18 infections decreased significantly between the pre-vaccination and post-vaccination periods by 68% (RR 0·32, 95% CI 0·19-0·52) and anogenital warts decreased significantly by 61% (0·39, 0·22-0·71) in girls 13-19 years of age. Significant reductions were also recorded in HPV types 31, 33, and 45 in this age group of girls (RR 0·72, 95% CI 0·54-0·96), which suggests cross-protection. Additionally, significant reductions in anogenital warts were also reported in boys younger than 20 years of age (0·66 [95% CI 0·47-0·91]) and in women 20-39 years of age (0·68 [95% CI 0·51-0·89]), which suggests herd effects. In countries with female vaccination coverage lower than 50%, significant reductions in HPV types 16 and 18 infection (RR 0·50, 95% CI 0·34-0·74]) and in anogenital warts (0·86 [95% CI 0·79-0·94]) occurred in girls younger than 20 years of age, with no indication of cross-protection or herd effects.


INTERPRETATION
Our results are promising for the long-term population-level effects of HPV vaccination programmes. However, continued monitoring is essential to identify any signals of potential waning efficacy or type-replacement.

Breast cancer is now the most commonly diagnosed cancer in the world. The most recent global cancer burden figures estimate that there were 2.26 million incident breast cancer cases in 2020 and the disease is the leading cause of cancer mortality in women worldwide. The incidence is strongly correlated with human development, with a large rise in cases anticipated in regions of the world that are currently undergoing economic transformation. Survival, however, is far less favourable in less developed regions. There are a multitude of factors behind disparities in the global survival rates, including delays in diagnosis and lack of access to effective treatment. The World Health Organization's new Global Breast Cancer Initiative was launched this year to address this urgent global health challenge. It aims to improve survival across the world through three pillars: health promotion, timely diagnosis, and comprehensive treatment and supportive care. In this article, we discuss the key challenges of breast cancer care and control in a global context. 

Understanding breast cancer as a global health concern

\n The Fourth World Conference on Women held in Beijing during September 4-15, 1995, was a major success. The platform for action adopted by consensus at the conference is comprised of the mission statement, a global framework, critical areas of concern, strategic objectives and actions, and institutional and financial arrangements. The conference was an extension of other large international conferences organized under UN initiative over the past 15 years. The Beijing platform of action aims to remove all obstacles to women's active participation in all spheres of public and private life through a full and equal share in economic, social, cultural, and political decision-making. The following concerns were defined by the conference: eradicating poverty, increasing school enrollment and eliminating gender inequalities in access to education, improving access to health care and eliminating gender inequalities in access to services, eliminating violence against women, mitigating the consequences of armed conflicts against women, securing equal access of men and women to economic resources and employment, providing equal participation of men and women in power structures and decision making, enhancing national mechanisms to promote the advancement of women, protecting the rights of girls and women, eradicating stereotypes about women, participating in the management of natural resources and environmental protection, and improving the status of girls.\n

Cervical cancer is an important global health problem. In this study we aimed to analyze trends in cervical cancer at the global, regional, and national levels from 1990 to 2019, to inform health service decision-making. Data on cervical cancer was extracted from the Global Burden of Disease study, 2019. Trends in cervical cancer burden were assessed based on estimated annual percentage change (EAPC) and age-standardized rate (ASR). Globally, decreasing trends were observed in incidence, death, and disability adjusted life years (DALYs) of cervical cancer from 1990 to 2019, with respective EAPCs of − 0.38 (95% confidence interval [CI]: − 0.41 to − 0.34), − 0.93 (95%CI: − 0.98 to − 0.88), and − 0.95 (95 CI%: − 1.00 to − 0.90). Meanwhile, decreasing trends were detected in most sociodemographic index (SDI) areas and geographic regions, particularly death and DALYs in Central Latin America, with respective EAPCs of − 2.61 (95% CI: − 2.76 to − 2.46) and − 2.48 (95% CI: − 2.63 to − 2.32); hhowever, a pronounced increasing trend in incidence occurred in East Asia (EAPC = 1.33; 95% CI: 1.12 to 1.55). At the national level, decreasing trends in cervical cancer were observed in most countries/territories, particularly DALYs in the Maldives (EAPC = − 5.06; 95% CI: − 5.40 to − 4.72), Whereas increasing trends were detected in Lesotho, Zimbabwe, and Bulgaria. Slowly decreasing trends in cervical cancer were detected worldwide from 1990 to 2019. Cervical cancer remains a substantial health problem for women globally, requiring more effective prevention and control strategies.

Prevention of Cervical Cancer in Sub-Saharan Africa: The Advantages and Challenges of HPV Vaccination.

The prevention and control of breast cancer in sub-Saharan Africa (SSA) is an increasingly critical public health issue. Breast cancer is the most frequent female cancer in SSA and mortality rates from this disease are the highest globally. Breast cancer has traditionally been considered a disease of high-income countries, and programs for early detection have been developed and implemented in these settings. However, screening programs for breast cancer in SSA have been less effective than in high-income countries. This article reviews the literature on breast cancer in SSA, focusing on early detection practices. It then examines the case for and against mammography and other early detection approaches for breast cancer in SSA. Women with breast cancer in SSA are younger compared with high-income countries. Most women present with advanced disease and because treatment options are limited, have poor prognoses. Delay between symptom onset and healthcare seeking is common. Engagement with early detection practices such as mammography and breast examination is low and contributes to late stage at diagnosis. While early detection of breast cancer through screening has contributed to important reductions in mortality in many high-income countries, most countries in SSA have not been able to implement and sustain screening programs due to financial, logistical and sociocultural constraints. Mammography is widely used in high-income countries but has several limitations in SSA and is likely to have a higher harm-to-benefit ratio. Breast self-examination and clinical breast examination are alternative early detection methods which are more widely used by women in SSA compared with mammography, and are less resource intensive. An alternative approach to breast cancer screening programs for SSA is clinical downstaging, where the focus is on detecting breast cancer earlier in symptomatic women. Evidence demonstrates effectiveness of clinical downstaging among women presenting with late stage disease. Approaches for early detection of breast cancer in SSA need to be context-specific. While screening programs with mammography have been effective in high-income countries, evidence suggests that other strategies might be equally important in reducing mortality from breast cancer, particularly in low-resource settings. There is a strong argument for further research into the feasability and acceptability of clinical downstaging for the control of breast cancer in SSA.

Improving early detection of breast cancer in sub-Saharan Africa: why mammography may not be the way forward.

Uganda has one of the highest age-standardized incidence rates of cervical cancer in the world. The proportion of Ugandan women screened for cervical cancer is low. To evaluate barriers and facilitators to accessing cervical cancer screening, we performed a systematic review of reported views of Ugandan women and healthcare workers. The aim of this review is to inform development of cervical cancer screening promotional and educational programs to increase screening uptake and improve timely diagnosis for women with symptoms of cervical cancer. Fourteen studies that included the views of 4386 women and 350 healthcare workers published between 2006 and 2019 were included. Data were abstracted by two reviewers and findings collated by study characteristics, study quality, and barriers and facilitators. Nineteen barriers and twenty-one facilitators were identified. Study settings included all districts of Uganda, and the quality of included studies was variable. The most frequently reported barriers were embarrassment, fear of the screening procedure or outcome, residing in a remote or rural area, and limited resources / health infrastructure. The most frequent facilitator was having a recommendation to attend screening. Understanding the barriers and facilitators to cervical cancer screening encountered by Ugandan women can guide efforts to increase screening rates in this population. Additional studies with improved validity and reliability are needed to produce reliable data so that efforts to remove barriers and enhance facilitators are well informed.

Barriers and facilitators to uptake of cervical cancer screening among women in Uganda: a systematic review

Background Pain during pregnancy is common, and its management is complex. Certain analgesics may increase the risk for adverse fetal and pregnancy outcomes, while poorly managed pain can result in adverse maternal outcomes such as depression and hypertension. Guidelines to assist clinicians in assessing risks and benefits of exposure to analgesics for the mother and unborn infant are lacking, necessitating evidence-based recommendations for managing pain in pregnancy. Methods A comprehensive literature search was conducted to assess pregnancy safety data for pharmacological and nonpharmacological pain management methods. Relevant clinical trials and observational studies were identified using multiple medical databases, and included studies were evaluated for quality and possible biases. Results Paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs) are appropriate for mild to moderate pain, but NSAIDs should be avoided in the third trimester due to established risks. Short courses of weaker opioids are generally safe in pregnancy, although neonatal abstinence syndrome must be monitored following third trimester exposure. Limited safety data for pregabalin and gabapentin indicate that these are unlikely to be major teratogens, and tricyclic antidepressants and serotonin-norepinephrine reuptake inhibitors have limited but overall reassuring safety data. Many of the included studies were limited by methodological issues. Conclusions Findings from this review can guide clinicians in their decision to prescribe analgesics for pregnant women. Treatment should be tailored to the lowest therapeutic dose and shortest possible duration, and management should involve a discussion of risks and benefits and monitoring for response. Further research is required to better understand the safety profile of various analgesics in pregnancy.

Medication Use and Pain Management in Pregnancy: A Critical Review.

Intimate partner violence (IPV) is an important public health issue as it impacts negatively on health, economic and development outcomes. In conflict affected northern Uganda, IPV prevalence is high and additional context-specific risk factors exist. People residing in this region have been displaced, exposed to war and violence, and had livelihoods destroyed. There are few studies examining IPV in this setting. In this study we aim to further understand the prevalence of IPV towards women and its associations in conflict affected northern Uganda. This was a cross-sectional, behavioural survey designed to capture quantitative information related to experiences of IPV among women living near two health clinics in rural northern Uganda. There were 409 women who participated in the survey. Data were analysed using logistic regression. High rates of emotional, physical and sexual IPV were found; 78.5% of women had experienced at least one type of IPV, and slightly more than half of the participants had experienced IPV in the 12 months prior to the survey. Many women felt that IPV was justified in certain situations. Significant determinants of IPV included alcohol abuse by the male partner (OR 2.22, 95% CI 1.34–3.73); partner having been in a physical fight with another man (OR 1.90, 95% CI 1.12–3.23); controlling behaviours by the male partner (OR 1.21, CI 1.08–1.36). and younger age of the woman (OR 0.95, 95% CI 0.92–0.98). Educational level was not independently associated with IPV. Our findings show that IPV is a significant issue in conflict affected northern Uganda, and attitudes that normalise and justify IPV are common. Alcohol abuse among young men in northern Uganda is highly prevalent and strongly associated with IPV towards women, as are controlling behaviours exhibited by the male partner. Interventions to reduce alcohol consumption among men in this region are likely to have important benefits in reducing the prevalence of IPV, and attitudes and behaviours that support IPV need to be further understood and addressed. Many women in conflict affected northern Uganda likely have additional risk factors for IPV related to previous exposure to war violence, however this was not directly measured in the present study. Further research into IPV in northern Uganda, and its relationship to exposure to conflict, is greatly needed.
