Health systems could play an important role in efforts to build vaccine confidence in communities that have been hardest hit by Covid-19. Boston Medical Center (BMC) health system, New England's largest safety-net hospital, along with its community partners, implemented a Covid Response Program aimed at building vaccine confidence. The program was supported by a multifaceted and multilingual communications campaign including: 1) traditional and social media channels with trusted messengers, 2) consistent and accessible core messaging, 3) transparent dialogue, and 4) partnership with state and local health government officials. Between December 2020 and June 2022, BMC disseminated 650 social media posts leading to 12 million impressions and more than 1.8 million post engagements. The campaign included a TikTok video later featured during the presidential inauguration, resulting in more than 3.7 million views. BMC's HealthCity digital publication released 20 articles gaining more than 73,000 views while the FAQ/vaccine scheduling site, translated into seven languages, reached 844,000 page visits. At six months into the vaccination program, 70% of BMC primary care patients 18 years or older had received at least one shot and 60% were fully vaccinated, having received either two mRNA doses or one adenovirus vaccine. The proportions rose to 82% with one dose and 75% fully vaccinated at 12 months. By 24 months into the program, 83% of BMC primary care patients had received at least one shot and 77% were fully vaccinated; however, notable differences existed by race/ethnicity. Seventy six percent of Black patients and 75% of Latino patients were fully vaccinated, compared with 85% of Asian and 81% White patients. Key lessons learned include the importance of a multilingual, multimedia campaign and the need for bidirectional communication that could quickly shift to address evolving issues.

Postpartum sacral insufficiency fracture is an uncommon occurrence that is often under-diagnosed because its symptoms of low back, buttock and groin pains may initially be attributed to physiologic biomechanical changes caused by pregnancy or to intervertebral disc disease. We present a case of bilateral sacral insufficiency fractures in a 37-year-old postpartum woman with osteopenic bone mineral density confirmed by dual energy X-ray absorptiometry. The symptoms were initially suspected to be of discogenic cause, and the fractures were incidentally appreciated at the edge of a lumbar spine magnetic resonance image. Therefore, it is important to keep in mind this potential diagnosis when examining imaging studies of postpartum patients. For women who present other risk factors of osteoporosis, imaging of the entire sacrum should be part of the imaging studies. If sacral stress fractures are diagnosed, further evaluation for bone mineral density and underlying metabolic bone disease is recommended.

Context: In multiple endocrine neoplasia type 1 (MEN1) characterized by tumors of parathyroid, enteropancreas, and anterior pituitary, missense mutations in the MEN1 gene product, menin, occur in a subset of cases. The mutant proteins are degraded by the proteasome. However, whether their expression and activity can be restored is not known., Objective: Our objective was to functionally characterize a panel of 16 menin missense mutants, including W423R and S443Y identified in new MEN1 families, with respect to protein stability, targeting to the proteasome and restoration of expression by proteasome inhibitors and expression and function by small interfering RNA technology., Methods: Flag-tagged wild-type (WT) and missense menin mutant expression vectors were transiently transfected in human embryonic kidney (HEK293) and/or rat insulinoma (Rin-5F) cells., Results: The majority of mutants were short-lived, whereas WT menin was stable. Proteasome inhibitors MG132 and PS-341 and inhibition of the chaperone, heat-shock protein 70 (Hsp70), or the ubiquitin ligase, COOH terminus of Hsp70-interacting protein (CHIP), by specific small interfering RNA, restored the levels of the mutants, whereas that of WT menin was largely unaffected. Inhibition of CHIP restored the ability of mutants to mediate normal functions of menin: TGF-β up-regulation of the promoters of its target genes, the cyclin-dependent kinase inhibitors p15 and p21 as well as TGF-β inhibition of cell numbers., Conclusion: When the levels of missense menin mutants that are targeted to the proteasome are normalized they may function similarly to WT menin. Potentially, targeting specific components of the proteasome chaperone pathway could be beneficial in treating a subset of MEN1 cases.

Objective: To report a case of life-threatening hyponatremia as a complication of a 4-week long low-iodine diet and highlight the risk factors for this complication by reviewing all previously reported cases., Methods: The clinical and biochemical data from the study patient are presented and the pertinent literature is reviewed. A risk analysis for this complication is highlighted., Results: A 66-year-old Vietnamese woman had a total thyroidectomy and bilateral neck lymph node dissection for papillary thyroid carcinoma. A whole body radioiodine scan demonstrated 2 foci of activity in the anterior neck. The patient received recombinant human thyrotropin (rhTSH) and was admitted for radioiodine therapy. She had strictly adhered to a low-iodine diet for 4 weeks in preparation for ablation. The patient was on a thiazide diuretic for her hypertension, which was discontinued on admission. On admission, the patient started feeling light-headed, dizzy, and nauseated. Blood tests revealed a critical serum sodium concentration of 107 mEq/L. Further investigations confirmed hypotonic hyponatremia, which had developed despite being euthyroid after receiving rhTSH. The patient was managed accordingly and made a full recovery., Conclusions: This case, in addition to the reviewed cases, emphasizes the importance of preventing and managing this rare but relatively dangerous complication. Based on an analysis of the reviewed cases, the risk factors for developing this complication are a prolonged low-iodine diet, the elimination of salt from the diet, and the use of thiazide diuretics. All patients in the reported cases were older than 65 years of age.
