To test how far into the protein-conducting channel of the translocon complex a nascent polypeptide domain must move before it can fold, we analyzed the folding of in vitro translated products of truncated mRNAs encoding the Semliki Forest virus capsid protease domain (Cp) during translocation into microsomes. Cp folded when the C-terminal linker connecting it to the peptidyltransferase center was 64 amino acids or longer. This means that to fold, Cp must exit the translocon channel. With an uncleaved signal sequence, about one out of four of the Cp domains could undergo folding with a C-terminal linker of only 38-66 amino acids. This suggested that the constraint imposed on folding by the translocon complex may be less stringent for signal-anchored membrane proteins.

BackgroundDespite Britain, Colombia, and some Mexican states sharing a health exception within their abortion laws, access to abortion under the health exception varies widely. This study examines factors that result in heterogeneous application of similar health exception laws and consequences for access to legal abortion. Our research adds to previous literature by comparing implementation of similar abortion laws across countries to identify strategies for full implementation of the health exception.MethodsWe conducted a cross-country comparative descriptive study synthesizing data from document and literature review, official abortion statistics, and interviews with key informants. We gathered information on the use and interpretation of the health exception in the three countries from peer-reviewed literature, court documents, and grey literature. We next extracted public and private abortion statistics to understand the application of the law in each setting. We used a matrix to synthesize information and identify key factors in the use of the law. We conducted in-depth interviews with doctors and experts familiar with the health exception laws in each country and analyzed the qualitative data based on the previously identified factors.ResultsThe health exception is used broadly in Britain, somewhat in Colombia, and very rarely in Mexican states. We identified five factors as particularly salient to application of the health exception in each setting: 1) comprehensiveness of the law including explicit mention of mental health, 2) a strong public health sector that funds abortion, 3) knowledge of and attitudes toward the health exception law, including guidelines for physicians in providing abortion, 4) dissemination of information about the health exception law, and 5) a history of court cases that protect women and clarify the health exception law.ConclusionsThe health exception is a valuable tool for expanding access to legal abortion. Differences in the use of the health exception as an indication for legal abortion result in wide access for women in Britain to nearly no access in Mexican states. Our findings highlight the difference between theoretical and real access to legal abortion. The interpretation and application of the health exception law are pivotal to expanding real access to abortion.

Background The misuse of conscientious objection (CO) is a significant barrier to legal abortion access in many countries, especially in Latin America. We examine the reasons for denial of legal abortion services in Mexico and Bolivia and identify ways to mitigate the misuse of CO. Methods We conducted 34 in-depth interviews and 12 focus group discussions in two states in Mexico and four departments in Bolivia. Results were coded and categorized using a thematic analysis approach. Results Denial of abortion services based on CO is widespread in health facilities in Mexico and Bolivia and is primarily employed for reasons other than moral, religious, or ethical considerations. The main reasons for denial of services based on CO is lack of knowledge about abortion-related laws and fear of legal problems in abortion service provision. Conversely, the main reason to provide services is to comply with relevant laws. Denying services under the guise of CO negatively impacts pregnant people and health care teams, including fewer safe abortion options and increased workload and stigma, respectively. Most respondents cited training and education on abortion law as the foremost way to mitigate the negative impacts of the misuse of CO. Conclusions For many health personnel, knowing, understanding, and following the law is reason enough to provide abortion services. Individuals who object due to lack of knowledge about laws and fear of legal problems represent a key population that can be sensitized and equipped with the necessary information and resources to provide legal abortion services.

Women in areas of the Americas with endemic Aedes mosquito populations are at risk for exposure to Zika virus, which can cause fetal brain abnormalities and associated congenital microcephaly. Individual health care providers may encounter health systems barriers to providing evidence-based care. We focus on Mexico and the U.S. state of Texas to highlight the role of health system factors in contraceptive access in the context of Zika, and highlight efforts in Puerto Rico as an example of efforts to improve access to contraception. In Mexico, states with the highest unmet need for contraception are low-lying, coastal states. The government recently announced an investment to combat Zika, but made no mention of family planning initiatives to assist women in preventing pregnancy. In Texas, the Department of State Health Services (DSHS) has issued recommendations to help women and men avoid mosquito-bites; the issue of whether women should plan or avoid pregnancy is not addressed. Puerto Rico has the largest number of confirmed cases of Zika virus in the US states and territories. Recently, the CDC Foundation launched the Zika Contraception Access Network (Z-CAN), which provides contraceptives at no cost to participating clinics in Puerto Rico. The Zika virus highlights weaknesses in health systems that make it difficult for women to use contraception if they want to delay births. Women across the globe, with or without Zika, need access to contraception to prevent unintended pregnancy, and providers require functioning health systems that offer the support to ensure access is a reality.

The COVID-19 pandemic led overburdened health care systems to deprioritize essential sexual and reproductive healthcare, including abortion and contraception care, while accelerating shifts in healthcare delivery to digital technologies. However, in many countries, including Pakistan, inequalities in access to digital technologies remain, presenting an opportunity for interventions that both increase access to deprioritized sexual and reproductive health and rights (SRHR) services and overcome the digital divide in delivering digital solutions to those in need of SRHR services. In June 2020, Ipas Pakistan partnered with Sehat Kahani (SK), a local health care NGO and telehealth service, and an existing network of Lady Health Workers (LHWs) to launch a novel hybrid telemedicine-community accompaniment pilot. The model linked women via LHWs with mobile devices to online providers for telemedicine consultations for SRH, including abortion services, contraception, and other gynecological consultations. In June 2020, we trained 98 LHWs and 22 telehealth doctors. Between June 2020 and March 2021, a total of 176 women were referred by LHWs for telehealth consultations. Among women who received abortion services, nearly all (90%) reported complete uterine evacuation. No serious adverse events were reported. Overall satisfaction was high; 81% reported being satisfied, and 86% said it is likely they would recommend the telehealth service to others. Data show that the provision of SRHR services via a telehealth-accompaniment model can be successfully implemented in Pakistan. Outcome data show high satisfaction and good clinical outcomes for women accessing care through this model. However, more data are needed to understand the full potential of this model. Barriers to digital health models, such as poor or inconsistent internet access, remain in places like Pakistan, especially in rural settings. This approach has its limitations but should be considered as an option in settings with similarly established community health networks and inequitable access to digital health.

ObjectiveFirst-trimester abortion is widely available in Mexico City since legalisation in 2007, but few data exist surrounding pharmacy staff knowledge and sales practices. We describe misoprostol availability, whether a prescription is required, and knowledge of the legal status of abortion and uses for misoprostol among pharmacy staff in Mexico City.MethodsData were collected from 174 pharmacies in Mexico City. One employee at each pharmacy was asked about availability, need for prescription, indications for misoprostol, and sociodemographic information. Our primary outcome was availability of misoprostol. We used descriptive and bivariate statistics to compare knowledge and practices by type of pharmacy and staff gender.Patients and public involvementNo patients were involved in this study.ResultsOf the 174 pharmacies, 65 were chain and 109 small independent. Misoprostol was available at 61% of sites. Only 49% of independent pharmacies sold misoprostol, compared with 81.5% of chain pharmacies (p<0.05). Knowledge of indications for misoprostol use was similar. The majority (80%) of respondents knew that abortion was legal in Mexico City, and 44% reported requiring a prescription for sale of misoprostol, with no significant difference between male and female staff or by pharmacy type.ConclusionsAvailability, requirement of a prescription, and knowledge of indications for use of misoprostol varies among pharmacies, resulting in differential access to medical abortion. Pharmacies may be a good place to target education for pharmacy staff and women about safe and effective use of misoprostol for abortion.

Objectives: Dilation and curettage is an outdated abortion procedure no longer recommended by the World Health Organization. However, use of dilation and curettage remains high in some countries, including Mexico. We aim to understand the factors that contribute to persistent use of dilation and curettage in Mexico. Methods: We conducted a mixed-methods study in two phases: (1) secondary quantitative data analysis from 40 Ipas-supported public hospitals in Mexico and (2) 28 in-depth interviews in 9 Ipas-affiliated hospitals with doctors, nurses, and hospital administrators. Results: Among our sample, 41% of abortions less than 13 weeks performed in 2019 were treated with dilation and curettage, while this increased to 67% of abortions at or above 13 weeks. Only 18% of induced abortions were performed with dilation and curettage compared to 44% of post-abortion care procedures. The main factor identified as determining use of dilation and curettage in in-depth interviews was availability of abortion supplies, both in terms of cleaning, storage, and maintenance of supplies and in the budgeting and procurement of supplies. Other factors included confidence in the efficacy of other methods, attitudes toward different methods, skill and training, and perceived benefits to patients. Conclusion: Ensuring supplies for recommended abortion methods are available is a key lever for any intervention aimed at reducing dilation and curettage use. However, as the doctor performing the abortion decides which method to use, individual factors such as lack of skill and mistrust in other procedures can become a particularly obstinate barrier to recommended method use. Localizing decision-making power in the hands of doctors is problematic in that it places the doctor’s preference above that of the person receiving the abortion. It is important to look deeply at the power structures that contribute to doctor-oriented models of abortion care.
