Due to the rapid spread of coronavirus, Vietnam introduced its first national partial lockdown on April 1st, 2020. The public relied on online sources, whether through official websites or phone-based applications, to acquire up-to-date health information, provide accurate instructions, and limit misinformation. This study aims to provide insight regarding the current level of awareness of the pandemic, and to identify associated factors in Vietnamese participants to recommend necessary interventions. A cross-sectional study was conducted using a web-based survey during the first week of the lockdown period. There were 341 observations collected using a snowball sampling technique. A Tobit multivariable regression model was used to identify factors associated with the demand for each category of health information. The most requested information was the latest updated news on the epidemic, followed by information about disease symptoms and updated news on the outbreak. The prevalence of diverse socioeconomic, demographic, and ethnic factors in Vietnam requires consideration of the specific health information needs of unique groups. Identifying group-specific demands would be helpful to provide proper information to fulfill each population group’s needs.

Background Approximately 18,000 Syrian refugees have resettled to the United States. Half of these refugees are children, whose age and refugee status jeopardize their abilities to attain quality healthcare. Information on Syrian refugees' health in the U.S. is limited. This qualitative study sought to explore Syrian refugee parents' beliefs, perspectives, and practices regarding their children's health through in-depth interviews. Methods Eighteen Syrian refugee parents residing in Cincinnati, Ohio were interviewed in Arabic by bilingual researchers using semi-structured in-depth interviews. The interviews were recorded, transcribed, and translated. Three members of the research team independently coded each interview using an inductive thematic analysis approach. Results Analysis identified four salient themes: stressors preclude health seeking behaviors, parents perceive health barriers, parents are dissatisfied with the healthcare system, and parents use resilience behaviors to overcome barriers. Stressors included poor housing and neighborhoods, reliving traumatic experiences, depression and anxiety, and social isolation. Dissatisfaction included emergency room wait times, lack of testing and prescriptions. Health barriers included missed appointments and inadequate transportation, translation services, health literacy and care coordination. Parents reported resilience through faith, by seeking knowledge, use of natural remedies, and utilizing community resources.

Lymphomas associated with breast implants are rare, with the most common being anaplastic large cell lymphoma (ALCL). Non-ALCL breast implant–associated lymphomas are even more rare, with only a small handful of such neoplasms reported to date. Given the need to better understand these pathologies as well as the increasing clinical and media attention being paid to these diseases, we review the available literature of hematolymphoid neoplasms other than ALCL associated with breast implants and describe the first case of a patient diagnosed with a primary breast implant–associated plasmacytoma. Level of Evidence: 5

Background: Surgical-site infection after implant-based breast reconstruction remains a leading cause of morbidity. Doxycycline is an antibiotic used to treat soft-tissue infections. The authors hypothesize that doxycycline-coated breast implants will significantly reduce biofilm formation, surgical-site infection, and inflammation after bacterial infection. Methods: Pieces of silicone breast implants were coated in doxycycline. In vitro studies to characterize the coating include Fourier transmission infrared spectroscopy, elution data, and toxicity assays (n = 4). To evaluate antimicrobial properties, coated implants were studied after methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa inoculation in vitro and in a mouse model at 3 and 7 days (n = 8). Studies included bacterial quantification, cytokine profiles, and histology. Results: Coated silicone breast implants demonstrated a color change, increased mass, and Fourier transmission infrared spectroscopy consistent with a doxycycline coating. Coated implants were nontoxic to fibroblasts and inhibited biofilm formation and bacterial adherence after MRSA and P. aeruginosa incubation in vitro, and measurable doxycycline concentrations at 24 hours were seen. In a mouse model, a significant reduction of MRSA and P. aeruginosa bacterial colonization after 3 and 7 days in the doxycycline-coated implant mice was demonstrated when compared to the control mice, control mice treated with intraperitoneal doxycycline, and control mice treated with a gentamicin/cefazolin/bacitracin wash. Decreased inflammatory cytokines and inflammatory cell infiltration were demonstrated in the doxycycline-coated mice. Conclusions: A method to coat silicone implants with doxycycline was developed. The authors’ doxycycline-coated silicone implants significantly reduced biofilm formation, surgical-site infections, and inflammation. Further studies are needed to evaluate the long-term implications.

IMPORTANCE Surgical site infections (SSIs) after vascularized reconstruction of the upper aerodigestive tract (UADT) are associated with considerable morbidity. The association between perioperative prophylaxis practices, particularly topical antisepsis, and SSIs remains uncertain.OBJECTIVE To assess the association between perioperative topical antisepsis and SSIs in patients undergoing vascularized reconstruction of the UADT. DESIGN, SETTING, AND PARTICIPANTSThis cohort study included patients from 12 academic tertiary care centers over an 11-month period, from July 1, 2020, to June 1, 2021. Patients undergoing open surgical procedures requiring a communication between the UADT and cervical skin with a planned regional pedicled flap, free flap, or both were included. Patients with an active infection at the time of surgical procedure were excluded. MAIN OUTCOMES AND MEASURESThe primary outcome measure was an SSI within 30 days of surgery. The association of demographic characteristics, perioperative antibiotic prophylaxis, surgical technique, and postoperative care with SSIs was assessed using univariable and multivariable analyses. The relative risk ratio and 95% CIs for developing SSI were calculated for each of the variables based on predetermined categories. Variables for which the relative risk 95% CI did not include the value of zero effect (relative risk = 1.00) were included in the multivariable model.RESULTS A total of 554 patients (median age, 64 years; range, 21-95 years; 367 men [66.2%]) were included. Cancer ablation was the most frequent reason for surgery (n = 480 [86.6%]). Overall, the SSI rate was 20.9% (n = 116), with most infections involving the head and neck surgical site only (91 [78.4%]). The median time to SSI diagnosis was 11 days (range, 1-28 days). Topical antisepsis mucosal preparation was performed preoperatively in 35.2% (195) and postoperatively in 52.2% (289) of cases. Ampicillin and sulbactam was the most common systemic antibiotic prophylaxis agent used (n = 367 [66.2%]), with 24 hours being the most common duration (n = 363 [65.5%]). On multivariable analysis, preoperative topical antisepsis mucosal preparation (odds ratio [OR], 0.49; 95% CI, 0.30-0.77) and systemic prophylaxis with piperacillin and tazobactam (OR, 0.42; 95% CI, 0.21-0.84) were associated with a decreased risk of a postoperative SSI. The use of an osseous vascularized flap was associated with an increased risk of postoperative SSI (OR, 1.76; 95% CI, 1.13-2.75). CONCLUSIONS AND RELEVANCEFindings of this study suggest that preoperative topical antisepsis mucosal preparation was independently associated with a decreased risk of SSIs in a 12-center multi-institutional cohort. Further investigation of the association between individual perioperative practices and the incidence of postoperative SSIs is necessary to develop evidence-based protocols to reduce SSIs after UADT reconstruction.
