Impact of the COVID-19 pandemic on access to and utilisation of services for sexual and reproductive health: a scoping review.

INTRODUCTION: The COVID-19 pandemic has negatively impacted health systems globally and widened preexisting disparities. We conducted a scoping review on the impact of the COVID-19 pandemic on women and girls' access to and utilisation of sexual and reproductive health (SRH) services for contraception, abortion, gender-based and intimate partner violence (GBV/IPV) and sexually transmitted infections (STIs). METHODS: We systematically searched peer reviewed literature and quantitative reports, published between December 2019 and July 2021, focused on women and girls' (15-49 years old) access to and utilisation of selected SRH services during the COVID-19 pandemic. Included studies were grouped based on setting, SRH service area, study design, population and reported impact. Qualitative data were coded, organised thematically and grouped by major findings. RESULTS: We included 83 of 3067 identified studies and found that access to contraception, in-person safe abortion services, in-person services for GBV/IPV and STI/HIV testing, prevention and treatment decreased. The geographical distribution of this body of research was uneven and significantly less representative of countries where COVID-19 restrictions were very strict. Access was limited by demand and supply side barriers including transportation disruptions, financial hardships, limited resources and legal restrictions. Few studies focused on marginalised groups with distinct SRH needs. CONCLUSION: Reports indicated negative impacts on access to and utilisation of SRH services globally, especially for marginalised populations during the pandemic. Our findings call for strengthening of health systems preparedness and resilience to safeguard global access to essential SRH services in ongoing and future emergencies.

Drug Eluting Embolization Particles for Permanent Contraception.

Medical technology that blocks the fallopian tubes nonsurgically could increase access to permanent contraception and address current unmet needs in family planning. To achieve total occlusion of the fallopian tube via scar tissue formation, acute trauma to the tubal epithelium must first occur followed by a sustained and ultimately fibrotic inflammatory response. Here, we developed drug-eluting fiber-based microparticles that provide tunable dose and release of potent sclerosing agents. This fabrication strategy demonstrates high encapsulation of physicochemically diverse agents and the potential for scalable manufacturing by utilizing free-surface electrospinning to generate material for fiber micronization. Manipulation of nanofiber formulation such as drug loading, drug hydrophobicity, polymer hydrophobicity, and crystallinity allowed for modulation of the sustained release properties of our fiber microparticles. We assessed various fibrous microparticle formulations in vivo using a newly developed and validated guinea pig model for contraception. We found that fiber microparticles with bolus release doxycycline effectively elicited acute trauma and those formulated with highly loaded phenyl benzoate caused sustained inflammation in the target organs. The demonstrated potency of these electrospun microparticles, as well as their embolic size and shape, suggests potential for proximal agglomeration and inflammatory activity in the fallopian tubes following transcervical delivery.

Telemedicine as an alternative way to access abortion in Italy and characteristics of requests during the COVID-19 pandemic.

INTRODUCTION: Induced abortion is legal in Italy but with restrictions. The online abortion provider Women on Web (WoW) serves as an alternative way to access abortion. The COVID-19 pandemic has affected sexual and reproductive health worldwide. Italy was one of the first countries hit by the pandemic and imposed strict lockdown measures. We aimed to understand why women requested WoW abortion in Italy and how this was affected by the pandemic. METHODS: We conducted an observational study analysing requests made to WoW before and during the pandemic. We analysed 778 requests for medical abortion from Italy between 1 March 2019 to 30 November 2020 and compared the characteristics of requests submitted before and during the pandemic. We also performed subgroup analysis on teenagers and COVID-19-specific requests. RESULTS: There was an increase in requests during the COVID-19 pandemic compared with the previous year (12% in the first 9 months). The most common reasons for requesting a telemedicine abortion through WoW were privacy-related (40.9%); however, this shifted to COVID-19-specific (50.3%) reasons during the pandemic. Requests from teenagers (n=61) were more frequently made at later gestational stages (p=0.003), had a higher prevalence of rape (p=0.003) as the cause of unwanted pregnancies, and exhibited less access to healthcare services compared with adult women. CONCLUSIONS: There was an increase in total demand for self-managed abortion during the pandemic and reasons for requesting an abortion changed, shifting from privacy-related to COVID-19-specific reasons. This study also highlighted the uniquely vulnerable situation of teenagers with unwanted pregnancies seeking self-managed abortion.

Vaginal delivery of vaccines.

Recent estimates suggest that one in two sexually active individuals will acquire a sexually transmitted infection by age 25, an alarming statistic that amounts to over 1 million new infections per day worldwide. Vaccination against STIs is highly desirable for alleviating this global burden of disease. Vaginal immunization is a promising strategy to combat transmission via the vaginal mucosa. The vagina is typically considered a poor inductive site for common correlates of adaptive immunity. However, emerging evidence suggests that immune tolerance may be overcome by precisely engineered vaccination schemes that orchestrate cell-mediated immunity and establish tissue resident memory immune cells. In this review, we will discuss the unique immunological milieu of the vaginal mucosa and our current understanding of correlates of pathogenesis and protection for several common STIs. We then present a summary of recent vaginal vaccine studies and explore the role that mucosal adjuvants and delivery systems play in enhancing protection according to requisite features of immunity. Finally, we offer perspectives on the challenges and future directions of vaginal vaccine delivery, discussing remaining physiological barriers and innovative vaccine formulations that may overcome them.

A Viral Toolbox of Genetically Encoded Fluorescent Synaptic Tags.

Fibronectin intrabodies generated with mRNA display (FingRs) are a recently developed tool for labeling excitatory or inhibitory synapses, with the benefit of not altering endogenous synaptic protein expression levels or synaptic transmission. Here, we generated a viral vector FingR toolbox that allows for multi-color, neuron-type-specific labeling of excitatory or inhibitory synapses in multiple brain regions. We screened various fluorophores, FingR fusion configurations, and transcriptional control regulations in adeno-associated virus (AAV) and retrovirus vector designs. We report the development of a red FingR variant and demonstrated dual labeling of excitatory and inhibitory synapses in the same cells. Furthermore, we developed cre-inducible FingR AAV variants and demonstrated their utility, finding that the density of inhibitory synapses in aspiny striatal cholinergic interneurons remained unchanged in response to dopamine depletion. Finally, we generated FingR retroviral vectors, which enabled us to track the development of excitatory and inhibitory synapses in hippocampal adult-born granule cells.
