#BabyLetsMove Physical Activity Feasibility Trial

Black adolescents who are pregnant represent a high-risk and understudied perinatal population in health research. Adolescent pregnancy (<20 years) is disproportionately prevalent among Blacks compared with Whites and is a prominent risk factor for obesity. Fortunately, metabolic consequences of increasing physical activity coupled with minimal sedentary time can mitigate biological imperils and behavioral interventions targeting perinatal populations have demonstrated efficacy for this approach. Intervention studies to promote physical activity and reduce sedentarism among Black, perinatal adolescents in disadvantaged, rural settings may be a promising strategy to prevent obesity and reduce disparities. In the proposed study, investigators will assess the feasibility and acceptability of #BabyLetsMove, a mobile health intervention targeting three behavioral goals: (1) limit TV time to less than 2 hours a day (sedentary behavior); (2) take 10,000 steps or more per day (physical activity); and (3) do 20 minutes or more of structured activity like prenatal yoga or dance videos per day (exercise). In the #BabyLetsMove feasibility trial investigators aim to conduct a single-arm, 4-week pilot with 20 Black adolescents (15- to 19-years) enrolled in Mississippi's Supplemental Nutritional Program for Women, Infants and Children (WIC) to test the intervention's feasibility and acceptability. Participants will receive one text message per day for 4-weeks targeting behavior change strategies and two health coaching sessions via mobile phone; an introduction session in week one and a problem-solving session in week three. Investigators will also use qualitative interviewing with additional adolescents (n=20) to solicit user feedback regarding the acceptability of intervention content and materials. Finally, in preparation for a pilot study using an effectiveness-implementation hybrid study design, investigators will conduct a pre-implementation evaluation using quantitative surveying (n=6 surveys) with WIC providers (n=60) to better under the culture and climate of WIC. Investigators hypothesize the #BabyLetsMove intervention will be acceptable to adolescents and a future pilot randomized controlled trial will be feasible. Investigators also anticipate identifying modifiable barriers and facilitators to implementing the intervention through WIC, which will help to design an implementation strategy with a high likelihood for uptake by WIC.

Pre-oxygenation With High-flow Nasal Cannula in Caesarian Section Under General Anesthesia

The investigators and other groups have demonstrated that high-flow nasal oxygen used during preoxygenation for emergency surgery is at least equally effective as preoxygenation compared to standard tight fitting mask. The investigators also have data from a recent study that indicates that high-flow nasal oxygen might decrease the risk of clinically relevant desaturation below 93% of arterial oxygen saturation. The studies investigating the concept of high-flow nasal oxygen has up to this date excluded pregnant women. Pregnant woman is a patient group with known difficulties to maintain adequate saturation levels during apnoea. Due to smaller functional residual capacity their oxygen stores after preoxygenation are smaller compared to patients with a normal body mass index. The pregnant woman also have a higher oxygen demand and metabolism due to the growing placenta and the fetus. Pregnant women are therefore a patient group where a method that could prolong time until desaturation would be even more valuable and potentially could save lives. Based on the above, the investigators now aim to conduct a clinical pilot study, where pregnant women undergoing caesarian section under general anesthesia are pre and perioxygenated with high-flow nasal oxygen. Data from that group will be compared with patients preoxygenated in a traditional manner with tight facemask. This study is done to evaluate an established technique on a patient category that in theory could gain a lot from it.

mWACh-PrEP: A SMS-based Support Intervention to Enhance PrEP Adherence During Pregnancy and Breastfeeding

In high HIV prevalence regions, women are at high risk for HIV during pregnancy and breastfeeding. To protect women and reach elimination of mother-to-child HIV transmission, the World Health Organization recommends offering oral tenofovir (TFV)-based pre-exposure prophylaxis (PrEP) to HIV-negative pregnant and postpartum women in high-burden settings. Although most pregnant Kenyan women with HIV risk factors accept PrEP when offered, >50% discontinue PrEP within 30 days of initiation and sub-optimal adherence is common. To date, no intervention studies to improve PrEP adherence include pregnant or postpartum women. The investigators adapted an SMS communication platform (mWACh) to send PrEP-tailored, theory-based SMS to facilitate adherence among pregnant women who initiate PrEP. In a non-randomized pilot, the investigators found that mWACh-PrEP recipients were more likely to persist with PrEP use and to self-report high adherence. The investigators propose a randomized trial to determine the effect of the mWACh-PrEP tool on PrEP adherence during pregnancy through the postpartum period. The investigators will also gather data on cost and delivery using the Proctor Implementation Outcomes Framework to expedite translation into routine practice. The overarching hypothesis is that mWACh-PrEP will improve PrEP adherence among mothers at-risk for HIV, be acceptable to patients and providers, and be cost-effective. The study will be executed via the following AIMS: Aim 1- To determine the effect of the mWACh-PrEP tool on PrEP adherence during pregnancy through the postpartum period among women who initiate PrEP within ANC-PrEP. We will conduct a 2-arm randomized trial comparing mWACh-PrEP vs standard of care (SOC, i.e. in-clinic adherence counseling) among HIV-uninfected pregnant women with high HIV acquisition risk (defined by validated risk score) who initiate PrEP. The primary outcome will be adherence at 6 months postpartum (TFV hair levels >0.038 ng/mg; consistent with 7 pills/ week). Secondary outcomes will include STI incidence, adherence cofactors, and prevention-effective adherence (time-varying alignment of adherence with risk behaviors). Exploratory outcomes will include HIV incidence and perinatal outcomes by arm. Hypothesis: mWACh-PrEP will increase PrEP adherence compared to SOC. Aim 2- Evaluate barriers and facilitators of mWACh-PrEP implementation within routine ANC. Using the Proctor framework, we assess acceptability and feasibility by conducting interviews and focus-groups with ANC-PrEP users, providers, and health planners. Hypothesis: Indications for readiness of mWACh-PrEP will be identified. Aim 3- Estimate the cost-effectiveness of implementing mWACh-PrEP within ANC-PrEP, per HIV infection and disability-adjusted life-year (DALY) averted. We use data from Aims 1 and conduct micro-costing and time-and-motion studies to estimate the cost of mWACh-PrEP from a payer perspective. The incremental cost-effectiveness ratio (ICER) per HIV infection and DALY averted compared to SOC will be calculated. Hypothesis: Incorporating data on PrEP and ANC outcomes with improve ICERs for mWACh-PrEP.

PREGBRAIN - Magnetic Stimulation of the Brain in Depressed Pregnant Women

Background: Depression during pregnancy is common, afflicting 10-20% of pregnant women. Nevertheless, many women want to avoid antidepressant treatment during pregnancy, due to the possible impact on the unborn child. rTMS (repetitive transcranial magnetic stimulation) is a method where an electromagnetic coil is placed close to the head. Magnetic pulses will induce an electrical current in specific nerve cells, depending on how the coil is placed. Thousands of patients have been treated with rTMS to date, and the effect on depressive symptoms is well documented, although the exact mechanism of the effect is not yet fully understood. Of late, an alternative treatment regime called intermittent theta burst stimulation (iTBS) has been developed. The treatment time per session for iTBS is much shorter than standard rTMS, which will render the treatment much more clinically acceptable. rTMS in pregnancy has not been extensively studied, but seems to have good effect and few side effects. Method: Pregnant women (N=60) with depressive symptoms will be assessed by a psychiatrist, and women fulfilling the criteria for a moderate-severe depressive episode can be included. Participants will be randomized to either active or sham treatment. Treatment will be administered during 20 days, once daily (4 minutes per session). A psychiatrist will assess depressive symptoms before, as well as 2 and 4 weeks after, treatment start. Women randomized to the sham treatment will, after the initial blind phase, be offered active treatment, following the same protocol as above. Women who have responded to the treatment, but are not in remission after the first four weeks will be offered an additional two weeks of iTBS treatment, in accordance with clinical protocol. Three, 6 and 12 months after the treatment is completed, all participants will be followed up via a web-based questionnaire. Apart from assessment of mood symptoms, treatment effects is also assessed using structural and functional magnetic resonance imaging (MRI). MRI will be performed once before treatment start, and once before at the very end of the blind phase of the study (four weeks). A random selection of the participating women will be invited to a sub-study and interviewed once during pregnancy as well as a second time 4-6 months postpartum. Questions will include inter alia their own description of being pregnant and depressed.
