Feasibility and Acceptability of a Video Group Psychoeducational Intervention with Latina Immigrant Mothers to Enhance Infant Primary care.

Standard models of well-child care may not sufficiently address preventive health needs of immigrant families. To augment standard individual well-child care, we developed a virtual group-based psychoeducational intervention, designed to be delivered in Spanish as a single, stand-alone session to female caregivers of 0-6 month-olds. The intervention included a video testimonial of an individual who experienced perinatal depression followed by a facilitated discussion by the clinic social worker and an orientation to relevant community resources by a community health worker. To assess feasibility and acceptability of the intervention, we conducted an open pilot within an academic pediatric practice serving predominantly Latinx children in immigrant families. Participants included 19 female caregivers of infants attending the practice, of whom 16 completed post-intervention measures and 13 completed post-intervention semi-structured interviews. Quantitative measures of acceptability and satisfaction with the intervention were high. We found preliminary effects of the intervention on postpartum depression knowledge and stigma in the expected direction. In interviews, participants described increases in their familiarity with postpartum depression and about relevant community resources, including primary care for caregivers. Participants reported an appreciation for the opportunity to learn from other caregivers and provided suggestions for additional topics of interest.

A mixed-methods study of parents' social connectedness in a group-based parenting program in low-income communities.

Group-based parent training (PT) is an evidence-based approach for strengthening parenting skills and reducing child behavior problems. However, there has been little research on the social connectedness (SC) formed among PT participants, particularly in low-income communities where parents may be more socially isolated. This study describes SC formed among parents in a group-based PT program implemented in their children's school and its association with changes in child behavior. Using a convergent mixed-methods design, data collection occurred between 2020 and 2022. Parents (n = 97) completed measures of their SC to other parents in their PT group and their child's behavior. Qualitative interviews with a representative subsample of parents (n = 17) were also conducted to understand parents' perceptions and experiences of SC within their PT group. Parents reported high levels of SC (M = 4.45 [range = 3.04-5 on scale of 1-5]; SD = 0.4). From baseline to postintervention, the number of children with child behavior problems significantly decreased (32.12%, 37.5% behavior intensity and problems, respectively). The magnitude of decline in child behavior problems was significantly related to parents' SC (b = -11.52, p = .02, SE = 4.99). Qualitative data confirmed high levels of SC, which parents linked to improvements in their parenting and children's behavior. Themes focused on the building of connections, committing to a safe space with parents who share similar goals, supporting one another, and gaining connections within the school environment and during the COVID-19 pandemic. Results highlight the potential synergistic effects of SC formed in the context of group-based PT with implications for strengthening parenting skills and children's well-being.

A Mixed-Methods Evaluation of Virtually Delivered Group-Based Mothers and Babies for Latina Immigrant Mothers.

BACKGROUND: Immigrant Latinas are at higher risk for postpartum depression (PPD) than the general perinatal population, yet face numerous barriers to accessing mental health services. The goal of this study was to pilot an enhanced virtual group delivery of a PPD prevention program, Mothers and Babies (MB), among immigrant Latinas engaged in early childhood programming. METHODS: Forty-nine Spanish-speaking mothers participated in one of four MB virtual groups, facilitated by trained bilingual staff at affiliated early learning centers. MB was enhanced to also target social determinants of health. A mixed-methods design was used to evaluate MB using participant interviews and pre-post surveys measuring depressive symptoms, parenting distress, and self-efficacy to manage emotions. RESULTS: On average, participants attended 69% of MB virtual sessions and rated group cohesiveness at a 4.6 on a 5-point scale. Paired-samples t tests showed significant reductions in depressive symptoms (Cohen's d = 0.29; p = .03) and parenting distress (Cohen's d = 0.31; p = .02), and improved self-efficacy to manage emotions (Cohen's d = -0.58; p < .001). Participants reported both benefits and drawbacks of the virtual format and provided largely favorable feedback on program enhancements. CONCLUSIONS: Results provide initial evidence for the acceptability, feasibility, and effectiveness of an enhanced virtual group PPD prevention program for immigrant Latinas, delivered in partnership with local early learning centers. These findings have important implications for extending the reach of preventive interventions among a population that faces many structural and linguistic barriers to traditional forms of mental health service delivery.

Centering the Right to Health of Childbearing People in the US During the COVID-19 Pandemic.

Childbearing people in the US have experienced the double burden of increased risks from infection and significant disruptions to access and quality of essential health care services during the COVID pandemic. A single person could face multiple impacts across the course of their reproductive trajectory. We highlight how failure to prioritize this population in the COVID-19 policy response have led to profound disruptions from contraception services to vaccination access, which violate foundational principles of public health, human rights and perpetuate inequities. These disruptions continued through the omicron surge, during which many health systems became overwhelmed and re-imposed earlier restrictions. We argue that an integrated pandemic response that prioritizes the healthcare needs and rights of childbearing people must be implemented to avoid deepening inequities in this and future pandemics.

Ecological niche modeling of Aedes mosquito vectors of chikungunya virus in southeastern Senegal.

BACKGROUND: Chikungunya virus (CHIKV) originated in a sylvatic cycle of transmission between non-human animal hosts and vector mosquitoes in the forests of Africa. Subsequently the virus jumped out of this ancestral cycle into a human-endemic transmission cycle vectored by anthropophilic mosquitoes. Sylvatic CHIKV cycles persist in Africa and continue to spill over into humans, creating the potential for new CHIKV strains to enter human-endemic transmission. To mitigate such spillover, it is first necessary to delineate the distributions of the sylvatic mosquito vectors of CHIKV, to identify the environmental factors that shape these distributions, and to determine the association of mosquito presence with key drivers of virus spillover, including mosquito and CHIKV abundance. We therefore modeled the distribution of seven CHIKV mosquito vectors over two sequential rainy seasons in Kédougou, Senegal using Maxent. METHODS: Mosquito data were collected in fifty sites distributed in five land cover classes across the study area. Environmental data representing land cover, topographic, and climatic factors were included in the models. Models were compared and evaluated using area under the receiver operating characteristic curve (AUROC) statistics. The correlation of model outputs with abundance of individual mosquito species as well as CHIKV-positive mosquito pools was tested. RESULTS: Fourteen models were produced and evaluated; the environmental variables most strongly associated with mosquito distributions were distance to large patches of forest, landscape patch size, rainfall, and the normalized difference vegetation index (NDVI). Seven models were positively correlated with mosquito abundance and one (Aedes taylori) was consistently, positively correlated with CHIKV-positive mosquito pools. Eight models predicted high relative occurrence rates of mosquitoes near the villages of Tenkoto and Ngary, the areas with the highest frequency of CHIKV-positive mosquito pools. CONCLUSIONS: Of the environmental factors considered here, landscape fragmentation and configuration had the strongest influence on mosquito distributions. Of the mosquito species modeled, the distribution of Ae. taylori correlated most strongly with abundance of CHIKV, suggesting that presence of this species will be a useful predictor of sylvatic CHIKV presence.

Fever versus fever: the role of host and vector susceptibility and interspecific competition in shaping the current and future distributions of the sylvatic cycles of dengue virus and yellow fever virus.

Two different species of flaviviruses, dengue virus (DENV) and yellow fever virus (YFV), that originated in sylvatic cycles maintained in non-human primates and forest-dwelling mosquitoes have emerged repeatedly into sustained human-to-human transmission by Aedes aegypti mosquitoes. Sylvatic cycles of both viruses remain active, and where the two viruses overlap in West Africa they utilize similar suites of monkeys and Aedes mosquitoes. These extensive similarities render the differences in the biogeography and epidemiology of the two viruses all the more striking. First, the sylvatic cycle of YFV originated in Africa and was introduced into the New World, probably as a result of the slave trade, but is absent in Asia; in contrast, sylvatic DENV likely originated in Asia and has spread to Africa but not to the New World. Second, while sylvatic YFV can emerge into extensive urban outbreaks in humans, these invariably die out, whereas four different types of DENV have established human transmission cycles that are ecologically and evolutionarily distinct from their sylvatic ancestors. Finally, transmission of YFV among humans has been documented only in Africa and the Americas, whereas DENV is transmitted among humans across most of the range of competent Aedes vectors, which in the last decade has included every continent save Antarctica. This review summarizes current understanding of sylvatic transmission cycles of YFV and DENV, considers possible explanations for their disjunct distributions, and speculates on the potential consequences of future establishment of a sylvatic cycle of DENV in the Americas.

The causes of porotic hyperostosis and cribra orbitalia: a reappraisal of the iron-deficiency-anemia hypothesis.

Porosities in the outer table of the cranial vault (porotic hyperostosis) and orbital roof (cribra orbitalia) are among the most frequent pathological lesions seen in ancient human skeletal collections. Since the 1950s, chronic iron-deficiency anemia has been widely accepted as the probable cause of both conditions. Based on this proposed etiology, bioarchaeologists use the prevalence of these conditions to infer living conditions conducive to dietary iron deficiency, iron malabsorption, and iron loss from both diarrheal disease and intestinal parasites in earlier human populations. This iron-deficiency-anemia hypothesis is inconsistent with recent hematological research that shows iron deficiency per se cannot sustain the massive red blood cell production that causes the marrow expansion responsible for these lesions. Several lines of evidence suggest that the accelerated loss and compensatory over-production of red blood cells seen in hemolytic and megaloblastic anemias is the most likely proximate cause of porotic hyperostosis. Although cranial vault and orbital roof porosities are sometimes conflated under the term porotic hyperostosis, paleopathological and clinical evidence suggests they often have different etiologies. Reconsidering the etiology of these skeletal conditions has important implications for current interpretations of malnutrition and infectious disease in earlier human populations.

Traumatic injuries and imperialism: the effects of Egyptian colonial strategies at Tombos in upper Nubia.

As circumstances of conquest change, leaders of empires must adapt their colonial strategies in order to be successful. One example of such modification in approach is the shift from Middle Kingdom to New Kingdom Egyptian colonial activities in Nubia. During the Middle Kingdom (2050-1650 BC) Egypt used aggressive military campaigns to subdue the strong Nubian polity at Kerma, resulting in the construction of fortresses and many victory stelae. In the subsequent New Kingdom period (1550-1050 BC) during which the Egyptian administration succeeded in occupying nearly all of Nubia, changes were necessary in conquest strategies. Diplomacy and cooperation may have replaced military action as mechanisms of control. This article investigates changes in imperial policy through the examination of traumatic injuries in human skeletal remains. Patterns of injuries in a sample from the site of Tombos, an Egyptian colonial cemetery in Nubia dating to the New Kingdom period, are compared with data on the patterns of injuries from Kerma, a cemetery dating to the Middle Kingdom period, published by Judd (2004). Analysis indicates a decrease in the level of traumatic injuries from Kerma to Tombos supporting the idea that through time the Egyptian administration modified their colonial strategy toward more nonviolent means. This article presents data on differences in the patterns of injury at Tombos and Kerma and explores possible explanations for this variation.

Regional, social, and evolutionary perspectives on treponemal infection in the Southeastern United States.

The origin and geographic distribution of syphilis, a form of treponemal infection, have long been regarded as among the most important medical riddles of prehistoric and historic disease evolution. In this study, we expand on previous discussions of the origin, evolution, and relationship of treponemal infections as they occur in the prehistoric southeastern United States. Individuals from 25 skeletal series (n = 2,410 individuals) were examined for cranial and dental lesions characteristic of treponemal infection. They lived between the Archaic period (8000-1000 BC) and protohistoric period (AD 1500-1600), and in physiographic zones from the coast to the mountains of Alabama, Florida, North Carolina, and Tennessee. Radial cranial scars were found for 47 individuals, but none of the four cases of dental lesions could be attributed to congenital syphilis. Differences in frequency of cranial lesions by region were minimal, with the least number of cases found for the mountains, but the frequency of positive cases tended to increase through time. It is suggested that increasing population density and changing behaviors, rather than novel strains of the treponemal pathogen, are responsible for the chronological increase in the frequency of positive cases.
