Mexican Immigrants in the US Living Far from the Border may Return to Mexico for Health Services

Background This study explores to what extent and why Mexican immigrants in the U.S. living far from the border return to Mexico for medical services. Methods Structured Spanish-language qualitative interviews were completed with a crosssectional sample of 10 Central Mexican immigrants living in Northern California and with 10 physicians and 25 former immigrants living in Central Mexico. Results Sixteen of the 35 current and former immigrants (46%) said they or a close friend or relative had returned to Mexico from the U.S. for health-related reasons. Participants returned to Mexico for care due to unsuccessful treatment in the U.S., the difficulty of accessing care in the U.S. and preference for Mexican care. Discussion Obtaining care in Mexico appears to be common. These findings have implications for the maintenance of continuity of care, for Mexico’s healthcare system, and for the impact of changing border policies on immigrant health.

US medical specialty global health training and the global burden of disease

Background Rapid growth in global health activity among US medical specialty education programs has lead to heterogeneity in types of activities and global health training models. The breadth and scope of this activity is not well chronicled. Methods Using a standardized search protocol, we examined the characteristics of US medical residency global health programs by number of programs, clinical specialty, nature of activity (elective, research, extended curriculum based field training), and geographic location across seven different clinical medical residency education specialties. We tabulated programmatic activity by clinical discipline, region and country. We calculated the Spearmans rank correlation coefficient to estimate the association between programmatic activity and country–level disease burden. Results Of the 1856 programs assessed between January and June 2011, there were 380 global health residency training programs (20%) working in 141 countries. 529 individual programmatic activities (elective–based rotations, research programs, extended curriculum–based field training, or other) occurred at 1337 specific sites. The majority of the activities consisted of elective–based rotations. At the country level, disease burden had a statistically significant association with programmatic activity (Spearmans ρ = 0.17) but only explained 3% of the total variation between countries. Conclusions There were a substantial number of US medical specialty global health programs, but a relative paucity of surgical and mental health programs. Elective–based programs were more common than programs that offer longitudinal experiences. Despite heterogeneity, there was a small but statistically significant association between program location and the global burden of disease. Areas for further study include the degree to which US–based programs develop partnerships with their program sites, the significance of this activity for training, and number and breadth of programs in medical specialty global health education in other countries around the world.

Burden of disease and barriers to the diagnosis and treatment of group a beta-hemolytic streptococcal pharyngitis for the prevention of rheumatic heart disease in Dar Es Salaam, Tanzania.

To understand patient and clinician attitudes toward Streptococcus pharyngitis and rheumatic heart disease prevention in Tanzania, data from 3 sources were obtained: a survey of 119 clinicians, outpatient rapid test screening, and interviews with 17 rheumatic heart disease patients. Patients do not seek care for sore throat. Clinicians stated that identifying and treating Streptococcus pharyngitis is not prioritized.

Emergency department presentation for uncomplicated acute rhinosinusitis is associated with poor access to healthcare

Uncomplicated acute rhinosinusitis (ARS) is most appropriately managed in an outpatient clinic setting. Some ARS patients present to emergency departments (EDs) for care. We investigates factors associated with ARS presentation to EDs versus outpatient settings.

Inhaled nitric oxide and cerebral malaria: basis of a strategy for buying time for pharmacotherapy.

There are approximately 225–600 million new malaria infections worldwide annually, with severe and cerebral malaria representing major causes of death internationally. The role of nitric oxide (NO) in the host response in cerebral malaria continues to be elucidated, with numerous known functions relating to the cytokine, endovascular and cellular responses to infection with Plasmodium falciparum. Evidence from diverse modes of inquiry suggests NO to be critical in modulating the immune response and promoting survival in patients with cerebral malaria. This line of investigation has culminated in the approval of 2 phase II randomized prospective clinical trials in Uganda studying the use of inhaled NO as adjuvant therapy in children with severe malaria. The strategy underlying both trials is to use the sytemic antiinflammatory properties of inhaled NO to “buy time” for chemical antiparasite therapy to lower the parasite load. This article reviews the nexus of malaria and NO biology with a primary focus on cerebral malaria in humans.

Socioeconomic determinants of overnight and weekend emergency department use for acute rhinosinusitis

Prior work has shown Medicaid and self‐pay insurance status is associated with emergency department (ED), rather than outpatient clinic, presentation for uncomplicated acute rhinosinusitis (ARS). We investigate whether the disparate use of ED resources for this nonemergent condition by patients with Medicaid and self‐pay insurance can be attributed to presentation overnight or on weekends.

Texting while driving: the development and validation of the distracted driving survey and risk score among young adults

Background Texting while driving and other cell-phone reading and writing activities are high-risk activities associated with motor vehicle collisions and mortality. This paper describes the development and preliminary evaluation of the Distracted Driving Survey (DDS) and score. Methods Survey questions were developed by a research team using semi-structured interviews, pilot-tested, and evaluated in young drivers for validity and reliability. Questions focused on texting while driving and use of email, social media, and maps on cellular phones with specific questions about the driving speeds at which these activities are performed. Results In 228 drivers 18–24 years old, the DDS showed excellent internal consistency (Cronbach’s alpha = 0.93) and correlations with reported 12-month crash rates. The score is reported on a 0–44 scale with 44 being highest risk behaviors. For every 1 unit increase of the DDS score, the odds of reporting a car crash increases 7 %. The survey can be completed in two minutes, or less than five minutes if demographic and background information is included. Text messaging was common; 59.2 and 71.5 % of respondents said they wrote and read text messages, respectively, while driving in the last 30 days. Conclusion The DDS is an 11-item scale that measures cell phone-related distracted driving risk and includes reading/viewing and writing subscores. The scale demonstrated strong validity and reliability in drivers age 24 and younger. The DDS may be useful for measuring rates of cell-phone related distracted driving and for evaluating public health interventions focused on reducing such behaviors.

Sex Differences in Faculty Rank Among Academic Surgeons in the United States in 2014

Objective: The aim of this study was to evaluate sex differences in full professorship among a comprehensive, contemporary cohort of US academic surgeons. Summary of Background Data: Previous work demonstrates that women are less likely than men to be full professors in academic medicine, and in certain surgical subspecialties. Whether sex differences in academic rank exist across all surgical fields, and after adjustment for confounders, is not known. Methods: A comprehensive list of surgeons with faculty appointments at US medical schools in 2014 was obtained from Association of American Medical Colleges (AAMC) faculty roster and linked to a comprehensive physician database from Doximity, an online physician networking website, which contained the following data for all physicians: sex, age, years since residency, publication number (total and first/last author), clinical trials participation, National Institutes of Health grants, and surgical subspecialty. A 20% sample of 2013 Medicare payments for care was added to this dataset. Multivariable regression models were used to estimate sex differences in full professorship, adjusting for these variables and medical school-specific fixed effects. Results: Among 11,549 surgeon faculty at US medical schools in 2014, 1692 (14.7%) were women. Women comprised 19.4% of assistant professors (1072/5538), 13.8% of associate professors (404/2931), and 7.0% of full professors (216/3080). After multivariable analysis, women were less likely to be full professors than men (adjusted odds ratio: 0.76, 95% confidence interval: 0.6–0.9). Conclusion: Among surgical faculty at US medical schools in 2014, women were less likely than men to be full professors after adjustment for multiple factors known to impact faculty rank.

Periostin as a Biomarker for Nasal Polyps in Chronic Rhinosinusitis

Objective Periostin is an extracellular matrix protein that is elevated in the sinonasal tissues of patients with chronic rhinosinusitis (CRS). The purpose of this study was to determine whether serum periostin could serve as a molecular biomarker of nasal polyp burden in sinonasal disease. Study Design Prospective cohort study. Setting Academic medical center. Subjects and Methods Serum periostin levels were measured by ELISA on blood samples collected from patients undergoing sinus surgery for CRS (n = 71), further stratified by phenotype as defined by nasal polyps and asthma. Results were compared with assays performed on control subjects (n = 62). Results Mean serum periostin levels were markedly elevated in patients with CRS versus controls (66.1 ng/mL [95% CI, 51.6-80.6] vs 38.7 ng/mL [95% CI, 34.4-42.9], respectively, P = .004). In addition, mean periostin levels were significantly higher in CRS patients with nasal polyps as compared with those without polyps (94.8 ng/mL [95% CI, 67.3-122.4] vs 41.1 ng/mL [95% CI, 35.2-47.0], respectively, P < .001). Periostin levels did not correlate with sex (P = .473), smoking history (P = .748), aspirin-exacerbated respiratory disease status (P = .136), oral steroid use within 1 month of surgery (P = .281), use of topical steroid nasal spray (P = .864), or number of prior sinus operations (P = .973). Conclusion Serum periostin appears to be a novel molecular biomarker for the presence of nasal polyps and may serve as an indicator of CRS endotypes.

Reversal of Smoking Effects on Chronic Rhinosinusitis after Smoking Cessation

Objective To understand whether the impact of smoking on chronic rhinosinusitis (CRS) is reversible after smoking cessation. Study Design Cross-sectional study. Setting Academic tertiary care rhinology clinic. Subjects and Methods A total of 103 former-smoker CRS patients and 103 nonsmoker CRS patients were prospectively recruited. The primary outcome measure was sinonasal symptom severity measured with the 22-item Sinonasal Outcomes Test (SNOT-22), and secondary outcome measures were general health-related quality of life (QOL) measured with the 5-dimensional EuroQol visual analog scale (EQ-5D VAS) and patient-reported CRS-related antibiotic and oral corticosteroid usage in the past year. Outcome measures were compared between cohorts and checked for association with time since cessation of smoking for former smokers. Results Compared with nonsmokers, former smokers had worse SNOT-22 score (P = .019) and EQ-5D VAS score (P = .001) and reported using more CRS-related antibiotics (P = .003) and oral corticosteroids in the past year (P = .013). In former smokers, every year was associated with a statistically significant improvement in SNOT-22 score (β = −0.48; 95% CI, −0.91 to −0.05; P = .032), EQ-5D VAS score (β = 0.46; 95% CI, 0.02-0.91; P = .046), and CRS-related oral corticosteroid use (relative risk = 0.95; 95% CI, 0.91-0.98; P = .001). Given the differences in our study outcome measures between former smokers and nonsmokers, we estimate that the reversible impacts of smoking on CRS may resolve after 10 to 20 years. Conclusions CRS patients who are former smokers have worse sinonasal symptomatology, QOL, and CRS-related medication usage than nonsmokers. Every year since cessation of smoking is associated improvements in sinonasal symptomatology, QOL, and CRS-related oral corticosteroid use, potentially reaching nonsmoker levels after 10 to 20 years.
