US Latina women experience disproportionately high cervical cancer incidence and mortality rates. These health disparities are largely preventable with routine pap tests and human papillomavirus (HPV) screening. This study tested the efficacy of a cervical cancer education intervention to improve risk factor knowledge, attitudes, self-efficacy, and self-reported behavior related to cervical cancer screening among low-income Latinas who had not been screened in the past 2 years, compared to a usual care control group. Low-income Latinas who had not had a pap test in the prior 2 years were recruited from three Federally Qualified Health Centers and randomly assigned to intervention and control groups, with in-person assessment at baseline and 6-month follow-up. Women in the intervention group received a one-time low-literacy cervical cancer education program through an interactive, multimedia kiosk in either English or Spanish based on their language preference. Compared to the control group, the intervention group demonstrated greater knowledge (p

BackgroundThe human papillomavirus (HPV) is the precursor and the single, most important risk factor for cervical cancer. It is also the most commonly sexually transmitted infection in the United States. An estimated 20 million persons are currently infected with the virus, with an estimated 6 million new infections occurring annually and 12,000 new cervical cancer cases and 4,000 cervical cancer deaths annually. The human papillomavirus (HPV) vaccine is thus an especially important preventive measure for racial/ethnic groups who bear an unequal burden of cervical cancer mortality.PurposeThis study aimed to develop a culturally and linguistically appropriate intervention to educate and empower Latino and Korean Americans to make an informed HPV vaccination decision for their minor children.MethodsA parent-focused HPV vaccine education DVD was developed through focus groups and cognitive interviews with Latino and Korean Americans parents of children ages 11-17. A randomized controlled efficacy trial was subsequently conducted with 708 Latino and Korean Americans parents to assess knowledge gains, decisional conflict, decision self-efficacy and informed decision-making resulting from viewing the intervention DVD.ResultsDifferences between treatment and control groups for pre-post changes in knowledge, informed decision-making and decisional conflict were statistically significant among the parents exposed to the education intervention DVD.ConclusionThe study demonstrated that a culturally and linguistically appropriate intervention DVD designed to educate parents about the risks and benefits of the HPV vaccine promoted informed decision-making regarding HPV vaccination among at-risk populations.

Context: Pregnant women in rural areas may give birth in either rural or urban hospitals. Differences in outcomes between rural and urban hospitals may influence patient decision making. Purpose: Trends in rural and urban obstetric deliveries and neonatal and maternal mortality in California were compared to inform policy development and patient and provider decision making in rural health care settings. Methods: Deliveries in California hospitals identified by the California Department of Health Services, Birth Statistical Master Files for years 1998 through 2002 were analyzed. Three groups of interest were created: rural hospital births to all mothers, urban hospital births to rural mothers, and urban hospital births to urban mothers. Findings: Of 2,620,096 births analyzed, less than 4% were at rural hospitals. Neonatal death rates were significantly higher in babies born to rural mothers with no pregnancy complications who delivered a normal weight baby vaginally at an urban hospital compared to urban mothers delivering at an urban hospital (0.2 [CI 0.2-0.4] deaths per 1,000 births versus 0.1 [CI 0.1-0.1]). Logistic regression analysis showed that delivery in a rural hospital was a protective factor compared to urban mothers delivering in an urban hospital, with an odds ratio of 0.8 (CI 0.6-0.9). Maternal death rates were not different. Conclusions: Rural obstetric services in this period showed favorable neonatal and maternal safety profiles. This information should reassure patients considering a rural hospital delivery, and aid policy makers and health care providers striving to ensure access to obstetric services for rural populations.

Background Botulism is a rare and potentially fatal paralytic disease caused by botulinum neurotoxin (BoNT). In April 2017, 4 California residents from 2 adjacent counties were hospitalized with suspected foodborne botulism, precipitating an investigation by state and local public health departments in California. Methods We interviewed suspected botulism patients and their families, inspected the suspect establishment, and collected suspect food. We tested patient sera, stool, and gastric aspirates using mouse bioassay for BoNT and/or culture for Clostridium botulinum. We tested suspect food and environmental samples for BoNT and confirmed presumptive positives using direct mouse bioassay and culture. We performed whole-genome sequencing on food and clinical isolates. Results From April 2017 through May 2017, 10 patients in the Sacramento area were hospitalized with laboratory-confirmed botulism; 7 required mechanical ventilation, and 1 died. Of 9 patients with information, all had visited Gas Station X before illness onset, where 8 reported consuming a commercial cheese sauce. BoNT/A and/or BoNT/A-producing C. botulinum were detected from each patient and from leftover cheese sauce. Clostridium botulinum isolates from 4 patients were closely related to cheese sauce isolates by whole-genome high-quality single-nucleotide polymorphism analysis. No other botulism cases associated with this cheese sauce were reported elsewhere in the United States. Conclusions This large foodborne botulism outbreak in California was caused by consumption of commercial cheese sauce dispensed at a gas station market. The epidemiologic and laboratory evidence confirmed the cheese sauce as the outbreak source. The cheese sauce was likely locally contaminated, although the mechanism is unclear.

Shiga toxins (Stx) are primarily associated with Shiga toxin-producing Escherichia coli and Shigella dysenteriae serotype 1. Stx production by other shigellae is uncommon, but in 2014, Stx1-producing S. sonnei infections were detected in California. Surveillance was enhanced to test S. sonnei isolates for the presence and expression of stx genes, perform DNA subtyping, describe clinical and epidemiologic characteristics of case-patients, and investigate for sources of infection. During June 2014-April 2015, we identified 56 cases of Stx1-producing S. sonnei, in 2 clusters. All isolates encoded stx1 and produced active Stx1. Multiple pulsed-field gel electrophoresis patterns were identified. Bloody diarrhea was reported by 71% of case-patients; none had hemolytic uremic syndrome. Some initial cases were epidemiologically linked to travel to Mexico, but subsequent infections were transmitted domestically. Continued surveillance of Stx1-producing S. sonnei in California is necessary to characterize its features and plan for reduction of its spread in the United States. [ABSTRACT FROM AUTHOR]

Background: Previous studies have shown an association between Mexican migration to the United States and an increased frequency of HIV high-risk behaviors among male Mexican migrants. However, the individual level change in these behaviors after migration has not been quantified., Objective: To estimate the change in HIV high-risk behaviors among Mexican migrants after migration to the United States., Methods: A case-crossover study was embedded in the California-Mexico Epidemiological Surveillance Pilot, a targeted, venue-based, sampling survey. We implemented the study from July to November 2005, studying 458 Mexican migrants at sites in rural and urban areas in Fresno County and San Diego County and directly comparing individual HIV high-risk behaviors before and after migration., Results: After migration, there were increases in the odds of male migrants engaging in sex with a sex worker [odds ratio (OR) = 2.64, P < 0.0001], sex while under the influence of drugs or alcohol (OR = 5.00, P < 0.0001), performing sex work (OR = 6.00, P = 0.070), and sex with a male partner (OR = 13.00, P = 0.001). Those male Mexican migrant subgroups at particularly elevated risk were those in the United States for more than 5 years, those from the youngest age cohort (18-29 years old), or those frequenting high-risk behavior venues and male work venues., Conclusions: Our results show that Mexican migrant men were significantly more likely to engage in several HIV high-risk behaviors after migration to the United States. However, a smaller proportion of men reported low condom use after migration, indicating increased adoption of some prevention methods. Our results also identified subgroups of Mexican migrants at elevated risk who should be targeted for HIV prevention interventions.
