Magnetic resonance (MR) imaging is an exciting new diagnostic modality that has created tremendous interest in the medical profession. Although not unparalleled, the excitement engendered by MR imaging conjures up memories of the “CAT fever” induced by introduction of X-ray computed tomography (CT) scanners in 1973 (19).

Root Cause

School shootings comprise a small proportion of childhood deaths from firearms; however, these shootings receive a disproportionately large share of media attention. We conducted a root cause analysis of 2 recent school shootings in the United States using lay press reports. We reviewed 1760 and analyzed 282 articles from the 10 most trusted news sources. We identified 356 factors associated with the school shootings. Policy-level factors, including a paucity of adequate legislation controlling firearm purchase and ownership, were the most common contributing factors to school shootings. Mental illness was a commonly cited person-level factor, and access to firearms in the home and availability of large-capacity firearms were commonly cited environmental factors. Novel approaches, including root cause analyses using lay media, can identify factors contributing to mass shootings. The policy, person, and environmental factors associated with these school shootings should be addressed as part of a multipronged effort to prevent future mass shootings.

Assimilation theories posit that cultural change is part and parcel of the assimilation process. That change can register in the symbols and practices that individuals invoke as part of an ethnic experience. But cultural change also includes the degree to which the mainstream takes up those symbols and practices as part of its composite culture. We develop a way to examine whether cuisine, an important component of ethnic culture, is part of the mainstream’s composite culture and the contextual factors associated with the presence of ethnic cuisine in the composite culture. We begin with a comparison of 761,444 reviews of Mexican, Italian, Chinese, and American restaurants across the United States from Yelp!, an online customer review platform. We find that reviews of Mexican restaurants mention ethnicity and authenticity much more than reviews of Italian and American restaurants, but less than reviews of Chinese restaurants, suggesting intermediate mainstreaming of Mexican cuisine. We then examine Mexican restaurant reviews in the 82 largest U.S. core-based statistical areas (CBSAs) to uncover the contextual factors associated with Mexican cuisine’s local mainstream presence. We find that Mexican food is less defined in ethnic terms in CBSAs with larger and more culturally distinct Mexican populations and at less-expensive restaurants. We argue that regional versions of the composite culture change as ethnic groups come to define a region demographically and culturally.

Presenting Symptoms

Object Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system, and its prevalence is continuing to increase in the United States. The diagnosis of intraventricular NCC (IVNCC) may be difficult, and surgery frequently fails to resolve symptoms. A retrospective review of magnetic resonance (MR) imaging characteristics and surgery-related outcomes may improve management strategies of this disease. Methods The authors report the presentations, neuroimaging characteristics, surgical management, and outcomes of 30 patients with IVNCC treated over a 10-year period (mean follow-up period 4 years). Cysts were located in the lateral ventricles (five cases), the third ventricle (five cases), and the fourth ventricle (21 cases). One patient had lesions in both the lateral and fourth ventricles. Presenting symptoms were related to hydrocephalus or mass effect from the lesions. All patients underwent computerized tomography (CT) and MR imaging of the brain. Treatment consisted of shunt implantation or primary excision of an IVNCC lesion. Outcomes after operations and reoperations were evaluated in light of enhancement characteristics on MR imaging. Computerized tomography scanning demonstrated IVNCC lesions in 10% of cases, and MR revealed lesions in 100% of cases. In patients in whom gadolinium (Gd) enhancement of IVNCC lesions was demonstrated on MR imaging, the surgery-related failure rate was higher and patients required reoperation, and in those in whom gadolinium enhancement was absent the surgery-related failure rate was lower (64 and 19%, respectively; p < 0.0002). Conclusions Magnetic resonance imaging is superior to CT scanning for detecting IVNCC lesions. The absence of pericystic Gd enhancement on MR imaging is an indication for excision of the lesions. If pericystic enhancement is present, shunt surgery should be performed, and craniotomy reserved for treatment of those patients with symptomatic lesions secondary to mass effect. A treatment algorithm based on patient symptoms, cyst location, and MR imaging Gd enhancement characteristics is proposed.

Political violence and international migration have the potential to disrupt leadership continuity in Hmong refugee communities in the United States. At the same time, clan and village authority structures from Laos favor leadership continuity despite dramatic social change. Data on 40 Hmong leaders in ten communities are used to determine if the indigenous sources of leadership continue to determine who becomes a leader after resettlement. The majority of leaders were leaders in Southeast Asia and have close kin who were leaders, indicating leadership continuity. Whether these leaders have held few or many leadership positions in the United States, however, is not determined by prior leadership or kinship, but by factors associated with acculturation. Initial leadership status in a host society is linked to authority structures from the homeland, but social change influences subsequent leadership careers.

e13531 Background: To examine trends in modifiable behaviorally related cancers among racial groups in the United States. Methods: Data were obtained from the United States Cancer Statistics (USCS) database for all cancers diagnosed between 2001 and 2017. Alcohol-associated cancers, HPV-associated, obesity-associated, physical inactivity-associated, and tobacco-associated were defined using ICD-O-3 site codes. SEER*Stat 8.3.8 and Joinpoint regression program 4.8.0.1 were used to calculate the trends of associated cancers expressed per 100,000. Results: In women, the incidence of all cancers has decreased significantly or remain unchanged for all racial groups in 2017, with the exception of an increase of HPV related cancers in white women (APC = 0.77%, p < 0.001), obesity related cancers in Hispanic women (APC = 0.46%, p < 0.001), and postmenopausal breast cancer in Black and Asian women (APC 0.78%, 1.06%, p < 0.001). The incidence of alcohol, tobacco, obesity, and physical inactivity associated cancer decreased significantly in men for all racial groups in 2017. HPV related cancers increased annually by 3.13% (p < 0.001) in White men and 0.90% in Asian men (p = 0.022). The highest decrease in modifiable factors associated with cancers was in physical inactivity related cancers in black men from the west (APC = -3.79, p < 0.001). The intersection of black race and U.S. region had the highest decreases in all cancers except obesity-related cancers where the intersection of Asian race and Midwest region had the highest decrease. Conclusions: In women, most modifiable factors associated with cancer are decreasing except in obesity related cancers and physical inactivity/obesity related postmenopausal breast cancer. In men, these rates of cancer are decreasing for all racial groups except HPV related cancers in White and Asian men.
