Polygyny has shown a positive association with intimate partner violence (IPV), yet the nature and mechanisms of this association are not well understood. This study uses data from rural Mozambique to distinguish women in polygynous unions by rank and co-residence. Findings show that senior wives report higher rates of violence than their junior-wife and monogamously married counterparts. At the same time, no difference is detected between junior wives and women in monogamous marriages. Additionally, the analysis finds that polygynously married women living away from their co-wives report higher rates of violence than both women co-residing with co-wives and women in monogamous unions, while the difference between the latter two categories is not statistically significant. However, the results also indicate that senior wives living away from their co-wives face particularly high risks of violence. These findings illustrate the social complexity of polygynous marriages and resulting differential vulnerabilities of women in them.

Labor migration is widespread and growing across the world. As migration grows, the economic outcomes of migration increasingly diversify, and so do its consequences for the well-being and health of both migrants and non-migrating household members. A considerable body of scholarship has examined the effects of migration on the physical and mental health of 'left-behind' household members. The impact of migration on mortality, particularly of non-migrating marital partners, is less well understood. Addressing this gap, we use data from a longitudinal survey of married women conducted over twelve years in rural Mozambique to examine the association between men's labor out-migration and their non-migrating wives' mortality. The analyses detect no significant differences when comparing non-migrants' wives to migrants' wives in the aggregate but point to instructive variation among migrants' wives according to the economic success of migration, as measured by the effects of migration on the household's material well-being. Specifically, women married to less successful migrants had higher mortality risks over the project span than women married to more successful migrants, regardless of other individual and household-level factors. Importantly for this setting with high HIV prevalence, the advantage of wives of more successful migrants is significant for HIV/AIDS-unrelated deaths but not for HIV/AIDS-related deaths. We situate these findings within the cross-national scholarship on migration and health.

Introduction: Ferric derisomaltose is the newest available parenteral iron formulation. Studies have demonstrated a good safety profile with improved tolerability compared to alternative parenteral iron formulations. To date there have been no reported acute, life-threatening cardiac events associated with ferric derisomaltose.

Case Report: An 86-year-old male who had previously tolerated routine iron infusions received a first dose of ferric derisomaltose at an outpatient infusion clinic. Six minutes into the infusion the patient became unresponsive with no palpable pulse. Return of spontaneous circulation was achieved after two minutes of chest compressions. Electrocardiogram showed complete heart block requiring transcutaneous pacing and vasopressor administration. The patient was transferred to the emergency department for stabilization and then admitted to the cardiac intensive care unit. During admission, the patient received a dual-chamber, permanent pacemaker without complication and was ultimately discharged.

Conclusion: It may be reasonable to consider parenteral iron as a toxicological etiology for patients presenting with complete heart block temporally associated with parenteral iron administration, particularly in patients with underlying conduction abnormalities.
