Short-Term Exposure to Waterpipe/Hookah Smoke Triggers a Hyperactive Platelet Activation State and Increases the Risk of Thrombogenesis.

OBJECTIVE: Cardiovascular disease is a major public health problem. Among cardiovascular disease's risk factors, tobacco smoking is considered the single most preventable cause of death, with thrombosis being the main mechanism of cardiovascular disease mortality in smokers. While tobacco smoking has been on the decline, the use of waterpipes/hookah has been rising, mainly due to the perception that they are less harmful than regular cigarettes. Strikingly, there are few studies on the negative effects of waterpipes on the cardiovascular system, and none regarding their direct contribution to thrombus formation. Approach and Results: We used a waterpipe whole-body exposure protocol that mimics real-life human exposure scenarios and investigated its effects, relative to clean air, on platelet function, hemostasis, and thrombogenesis. We found that waterpipe smoke (WPS)-exposed mice exhibited both shortened thrombus occlusion and bleeding times. Further, our results show that platelets from WPS-exposed mice are hyperactive, with enhanced agonist-induced aggregation, dense and α-granule secretion, αIIbß3 integrin activation, phosphatidylserine expression, and platelet spreading, when compared with clean air-exposed platelets. Finally, at the molecular level, it was found that Akt (protein kinase B) and ERK (extracellular signal-regulated kinases) phosphorylation are enhanced in the WPS and in nicotine-treated platelets. CONCLUSIONS: Our findings demonstrate that WPS exposure directly modulates hemostasis and increases the risk of thrombosis and that this is mediated, in part, via a state of platelet hyperactivity. The negative health impact of WPS/hookah, therefore, should not be underestimated. Moreover, this study should also help in raising public awareness of the toxic effects of waterpipe/hookah.

Development of a community pharmacy human papillomavirus vaccine program for underinsured university students along the United States/Mexico border.

OBJECTIVE: To describe the development and implementation of a human papillomavirus (HPV) vaccine patient assistance program (PAP) for university students, and to acquire information on the number who accessed the program and completed the series. SETTING: University of Texas at El Paso University Student Health Clinic Pharmacy, Fall 2011-Spring 2014. PRACTICE DESCRIPTION: A community pharmacy located within the university student health clinic providing services to an underinsured student population. PRACTICE INNOVATION: Existing evidence shows the benefit of using PAP in community pharmacies but is nonspecific regarding the use of PAP for vaccines in an uninsured and underinsured Hispanic student population. The implementation of this unique HPV vaccine program in a community setting aims to increase awareness, access, and rates. MAIN OUTCOME MEASURES: Primary measures included results from a needs-assessment questionnaire that were used to implement the HPV vaccine program. After implementation, utilization data were collected on the number of students who qualified and enrolled in the HPV PAP and the number of students who completed the HPV series. RESULTS: The preliminary data from a needs assessment indicated that a majority (72.1%, n = 80) of students did not understand how HPV is transmitted. A total of 89 students qualified for PAP. The majority were women (81%). A total of 71 students (79.8%) received their second dose and 43 (48.3%) completed the series. CONCLUSIONS: Although pharmacists continue to provide vaccine services, minorities such as the Hispanic population continue to be underimmunized. Students may not be taking the proper precautions to prevent the acquisition of HPV. For these reasons services such as this HPV vaccine program are warranted. Pharmacists need to continue to educate and advocate on the importance of vaccines and how they prevent disease.

Spanish-speaking patients' satisfaction with clinical pharmacists' communication skills and demonstration of cultural sensitivity.

OBJECTIVE To assess Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity, while controlling for patients' sociodemographic, clinical, and communication factors, as well as pharmacist factors, and to identify clinical pharmacists' cultural factors that are important to Spanish-speaking patients. DESIGN Cross-sectional study. SETTING Central Texas during August 2011 to May 2012. PARTICIPANTS Spanish-speaking patients of federally qualified health centers (FQHCs). MAIN OUTCOME MEASURE(S) A Spanish-translated survey assessed Spanish-speaking patients' satisfaction with their clinical pharmacists' communication skills and demonstration of cultural sensitivity. RESULTS Spanish-speaking patients (N = 101) reported overall satisfaction with their clinical pharmacists' communication skills and cultural sensitivity. Patients also indicated that pharmacists' cultural rapport (e.g., ability to speak Spanish, respectfulness) was generally important to Spanish speakers. Multiple linear regression analyses showed that cultural rapport was significantly related to satisfaction with pharmacists' communication skills and demonstration of cultural sensitivity. CONCLUSION Overall, patients were satisfied with pharmacists' communication skills and cultural sensitivity. Patient satisfaction initiatives that include cultural rapport should be developed for pharmacists who provide care to Spanish-speaking patients with limited English proficiency.

Pharmacological management of traumatic brain injury and implications for speech language pathology.

This article provides an overview of the pharmacological management of traumatic brain injury (TBI). A basic introduction to key pharmacokinetic and pharmacodynamic principles is used to guide the reader. The goals of the pharmacological management of TBI are explained starting with mild TBI. The main medications used for each medical condition are described with a primary emphasis of effects that may interfere with the role of speech-language pathology (SLP). Some medications may interfere with cognitive, motor, and neuromuscular functions, and others may cause ototoxicity. A basic overview of the pharmacological management of moderate to severe TBI is included because the SLP practitioner may encounter patients with TBI during the recovery phase. The importance of assessment of swallowing evaluations is discussed because the oral route of administration of medications is preferred once the patient is stable.

Medication use practices and perceptions among patients in a U.S.-Mexico border community.

OBJECTIVE: To identify themes surrounding medication use practices and perceptions among individuals from a U.S.-Mexico border community recruited to participate in focus groups. METHODS: This study was conducted in El Paso, TX. Adult participants considered to be at risk for medication therapy problems (i.e., older adults, pregnant or breast-feeding women, parents of young children) were recruited for participation. Focus groups and a survey were used to evaluate perceptions, concerns, and patterns of use of U.S. medications, Mexican medications, and herbal products. RESULTS: A sample of 73 adults, most of whom were Hispanic women (n = 60 [82%]), were recruited for participation in seven focus groups. Across groups, the majority participated in the older adult cohort (n = 42 [58%]), reported having an annual household income of less than $15,000 (n = 57 [78%]), and identified that they had less than a high school education (n = 40 [55%]). Four dominant themes emerged from the participants who completed both the survey and focus groups: (1) a "comfort" level for using a combination of U.S. medications, Mexican medications, and herbal products; (2) customary use of different drug information sources including physicians, Mexican pharmacy staff, U.S. pharmacists, and family members; (3) inconsistent levels of confidence in interpreting, measuring, and using medications; and (4) a sense of frustration regarding medication costs, which led participants to seek alternative options. CONCLUSION: These qualitative results provide an increased understanding of medication use practices and perceptions in this population. Findings such as these can provide guidance and insight into the development of interventions to improve safe and effective medication use.

Medication literacy in Spanish and English: psychometric evaluation of a new assessment tool.

OBJECTIVE: To evaluate the psychometric properties of a newly developed Medication Literacy Assessment in Spanish and English (MedLitR xSE). DESIGN: Descriptive, nonexperimental, cross-sectional study. SETTING: El Paso, TX, from December 2006 to June 2009. PARTICIPANTS: 181 English- or Spanish speaking adults. INTERVENTION: Survey administered in two phases. MAIN OUTCOME MEASURES: Descriptive statistics, internal consistency, confirmatory factor analysis (CFA) and fit indices, and criterion-related validity. RESULTS: The 20-item MedLitR xSE tool showed adequate internal consistency and reliability, and CFA revealed overall good model fit. In phase 2, the shorter 14-item MedLitR xSE showed good total test reliability and correlated well with the Short Test of Functional Health Literacy in Adults. Item response theory analyses showed no language bias and a one-dimensional (i.e., one factor) model of medication literacy. CONCLUSION: The initial and latest shorter version of the MedLitR xSE tool demonstrated good psychometric properties. This tool may provide a new option to assess "medication literacy" in English and Spanish.

Helicobacter pylori eradication and change in markers of iron stores among non-iron-deficient children in El Paso, Texas: an etiologic intervention study.

OBJECTIVES: We assessed whether Helicobacter pylori eradication was followed by changes in iron stores among non-iron-deficient children. MATERIALS AND METHODS: Double-blind randomized intervention trial on 110 asymptomatic 3- to 10-year-olds with H pylori infection assigned to any of the following 4 arms: both quadruple eradication and iron supplementation, either quadruple sequential eradication or iron supplementation, or placebo only. Hemoglobin, transferrin saturation, and serum ferritin were measured at baseline and 8 months later to assess changes according to study arm, H pylori infection status at ≥45 days, and cytotoxin-associated gene product A status. RESULTS: Intent-to-treat (n = 110) and per-protocol (n = 90) analyses revealed no differences across study arms in changes of iron stores. However, we found that those who had their infection eradicated had a 3-fold increased average change from baseline serum ferritin compared with that of children who remained infected (P < 0.05). Eradication of infection by cytotoxin-associated gene product A negative strains was associated with a larger ferritin increase. CONCLUSIONS: In this double-blind randomized trial, the first among non-iron-deficient, asymptomatic H pylori-infected children living in the contiguous United States, we found no effect of H pylori eradication regarding changes in iron stores. However, those who had their infection eradicated at follow-up had a significantly larger increase in serum ferritin from baseline.

Double-blind randomized trial of quadruple sequential Helicobacter pylori eradication therapy in asymptomatic infected children in El Paso, Texas.

OBJECTIVES: We assessed the efficacy of a novel quadruple sequential 10-day eradication therapy, its compliance, and reported adverse events in a sample of asymptomatically Helicobacter pylori-infected children in El Paso, Texas, as part of a study aiming to assess the influence of this infection on the levels of markers of iron stores. PATIENTS AND METHODS: Using a double-blind randomized trial design, 110 asymptomatic children ages 3 to 11 with H pylori infection were randomly assigned to receive either a 10-day course of sequential eradication therapy plus 6 weeks of iron supplementation, eradication therapy plus placebo, iron supplementation plus placebo, or placebo only. H pylori infection status was assessed ≥45 days after treatment using the urea breath test. Analyses compared the proportion of subjects cured according to assignment to and completion of the sequential eradication therapy. RESULTS: Intent-to-treat and per-protocol analyses indicated that 44.3% and 52.9%, respectively, of the children receiving the novel quadruple sequential therapy had their infection eradicated compared with 12.2% and 15.4% in the arms receiving iron or placebo only, respectively (P < 0.001 in both analyses). Study medications were taken with no or only mild adverse events in most children. CONCLUSIONS: A quadruple sequential regimen eradicated H pylori in only half the asymptomatic children receiving this treatment. There was no difference in the cure rates of those receiving iron supplementation and those receiving placebo.

The JUUL E-Cigarette Elevates the Risk of Thrombosis and Potentiates Platelet Activation.

BACKGROUND: Smoking is the main preventable cause of death in the United States and worldwide and is associated with serious cardiovascular health consequences, including thrombotic diseases. Recently, electronic cigarettes (e-cigarettes) and, in particular JUUL, have attained wide popularity among smokers, nonsmokers, pregnant females, and even the youth, which is alarming. Interestingly, there is/are no information/studies regarding the effect of JUUL on cardiovascular diseases, specifically in the context of modulation of platelet activation. Thus, it is important to discern the cardiovascular disease health risks associated with JUUL. METHODS AND RESULTS: We used a passive e-vape vapor inhalation system where C57BL/6J mice (10-12 weeks old) were exposed to JUUL e-cigarette vape. Menthol flavored JUUL pods containing 5% nicotine by weight were used as the e-liquid. Mice were exposed to a total of 70 puffs daily for 2 weeks; 3-second puff duration, and 25-second puff interval. The effects of JUUL relative to clean air were analyzed, on mouse platelet function in vitro (eg, aggregation) and in vivo (eg, FeCl3-induced carotid artery injury thrombosis model). Our results indicate that short-term exposure to JUUL e-cigarette causes hyperactivation of platelets and shortens the thrombus occlusion as well as hemostasis/bleeding times, relative to clean air (medians of 14 vs. 200 seconds, P < .01 and 35 vs. 295 seconds, P < .001, respectively). CONCLUSION: Our findings document-for the first time-that short-term exposure to the JUUL e-cigarette increases the risk of thrombotic events, in part by modulating platelet function, such as aggregation and secretion, in mice.

Prevalence of polypharmacy, polyherbacy, nutritional supplement use and potential product interactions among older adults living on the United States-Mexico border: a descriptive, questionnaire-based study.

BACKGROUND AND OBJECTIVE: The use of multiple medications, herbs or nutritional supplements can lead to adverse consequences, particularly in the elderly. A significant consequence resulting from polypharmacy, polyherbacy and nutritional supplement use is the potential for interactions to occur among the various products. The primary objective of this study was to estimate the prevalence of polypharmacy, polyherbacy, nutritional supplement use and potential product interactions among older adults living on the US-Mexico border. METHODS: This was a descriptive study that involved the administration of a bilingual (English/Spanish) questionnaire to a convenience sample of adults aged >or=60 years recruited from senior centres located within the most populated US-Mexico border region from June 2005 to March 2006. Participant demographics were collected in addition to information about current use of prescription medications, over-the-counter (OTC) medications, herbal products and nutritional supplements (i.e. nutraceuticals and vitamins or minerals). The outcomes measured were the number of prescription medications, OTC medications, herbal products, vitamins/minerals and nutraceuticals per participant. Furthermore, the number of potential interactions and major interactions between drugs, herbal products and nutritional supplements were identified for each participant. Additionally, product use patterns between men and women and among locations within the border region were compared. RESULTS: One-hundred-and-thirty participants (mean age 71.4 years) were recruited to complete the questionnaire. The prevalence of polypharmacy among all participants was 72.3% (n = 94), with 38.5% (n = 50) taking five or more concomitant medications (major polypharmacy). Twenty-one participants (16.2%) in the study sample reported taking two or more herbal products (polyherbacy). Thirty-four participants (26.2%) reported taking two or more vitamin/mineral supplements and nine (6.9%) reported using two or more nutraceuticals. Participants living on the US side of the border had higher rates of major polypharmacy, polyherbacy and use of nutritional supplements than those living on the Mexican side of the border. Overall, there were no significant differences in medication, herbal product and nutritional supplement use patterns between men and women. Evaluation of potential interactions revealed that 46.2% (n = 60) of participants were at risk of having at least one potential drug-drug interaction. Regarding drug and herbal product-supplement interactions, 31.5% (n = 41) of participants were at risk of having at least one possible interaction. CONCLUSIONS: The prevalence of polypharmacy among older adults living on the US side of the border was similar to national trends (estimates suggest that one-quarter to one-half of US adults aged >or=65 years take five or more medications). However, polypharmacy was less common in older adults living on the Mexican side of the border. Additionally, herb use was higher in older adults living on the US-Mexico border than has been reported in national surveys of US adults, which indicate that less than one-quarter of adults have used a herbal product within the previous 12 months. Furthermore, this study demonstrated that older adults living on the US side of the border consumed more herbs and nutritional supplements than their Mexican counterparts. In addition to describing product use patterns on the border, these findings suggest that almost half of the older adult participants were at risk for a potential drug-drug interaction, with approximately one-third having a potential interaction between their medications, herbs or nutritional supplements.

Cross-border purchase of medications and health care in a sample of residents of El Paso, Texas, and Ciudad Juarez, Mexico.

BACKGROUND: We examined data from a US-Mexico bi-national survey conducted among adult residents of El Paso, Texas, and Ciudad Juarez, Mexico, to assess frequency of purchase of medications and use of health care services across the border. METHODS: We analyzed questionnaire data from face-to-face interviews of 1000 randomly selected adults on both sides of the border to assess prevalence and prevalence ratios using log binomial logistic regression analysis. RESULTS: One-third of adult residents of El Paso and 5% of those in Ciudad Juarez reported crossing the border to purchase medications (P < .001). Lack of health insurance in the United States was associated with crossing the border to purchase medications. Nine percent and 7% of US residents traveled to Mexico seeking dental and medical care, respectively. Mexican nationals traveling to the United States to purchase medications or health care services were more likely to be uninsured and more-educated men. CONCLUSION: US residents of areas along the border in close proximity to Mexico often travel south to purchase medications. Other health care services are also utilized, although at lower rates. These patterns may be attributed to a number of barriers to health care in the United States.

Study of methicillin-resistant Staphylococcus aureus on the U.S./Mexico border.

BACKGROUND: El Paso, Texas and Ciudad Juarez, Mexico comprise the largest U.S./Mexico border population. METHODS: Bacterial samples were collected from two hospitals in El Paso and two in Ciudad Juarez and transported to a reference microbiology laboratory in El Paso for microbial identification and antimicrobial susceptibility testing according to NCCLS standards. The presence of the MecA gene, and the prevalence of both the SSCmec IV element and the Panton-Valentine leukocidin were investigated by PCR in all MRSA isolates. RESULTS: A total of 201 isolates in El Paso and 128 in Ciudad Juarez of Staphylococcus aureus were identified, of those, MRSA were significantly more prevalent in El Paso than in Ciudad Juarez [89 (44.3%) versus 10 (7.8%) respectively (p<0.0001)]. Thirty one (35%) of MRSA strains isolated in El Paso were community associated. CONCLUSION: Significantly higher prevalence of MRSA infections was documented in El Paso compared to Ciudad Juarez.

Adequacy of outpatient care among hospitalized adult asthmatics in a southwest US border city.

Over 3 years we studied the baseline degree of asthma severity and the adequacy of the usual medical management among asthmatics admitted to a large US-Mexican border county hospital. The study design consisted of 2 years of retrospective chart review and 1 year of prospective semistructured interview collection. Patients were at least 18 years of age and required acute care and hospital admission for asthma exacerbations. The 127 patients studied accounted for 166 hospital admissions for asthma related primary diagnoses. Most were Hispanic and medically indigent, and only 39% of patients whose asthma severity indicated the use of inhaled corticosteroid medications reported taking them. Most of the hospitalized asthmatic patients studied were on inadequate outpatient medical regimens for the baseline severity of their asthma. Underuse of inhaled corticosteroids was the predominant medication deficiency. Other shortcomings identified in their routine management included a lack of pulmonary function testing, basic asthma education, and treatment by a practitioner qualified in the care of chronic asthma.

Yellow Oleander Seed, or "Codo de Fraile" (Thevetia spp.): A Review of Its Potential Toxicity as a Purported Weight-Loss Supplement.

The Dietary Supplements and Health Education Act (DSHEA), passed by the United States Congress in October of 1994, defines herbal products as nutritional supplements, not medications. This opened the market for diverse products made from plants, including teas, extracts, essential oils, and syrups. Mexico and the United States share an extensive border, where diverse herbal products are available to the public without a medical prescription. Research undertaken in the neighboring cities of Ciudad Juarez, Mexico, and El Paso, Texas, USA, shows the use of herbs is higher in this border area compared to the rest of the United States. A portion of the population is still under the erroneous impression that "natural" products are completely safe to use and therefore lack side effects. We review the dangers of ingesting the toxic seed of Thevetia spp. (family Apocynaceae), commonly known as "yellow oleander" or "codo de fraile," misleadingly advertised on the Internet as an effective and safe dietary supplement for weight loss. Lack of proper quality control regarding herbs generates a great variability in the quantity and quality of the products' content. Herb-drug interactions occur between some herbal products and certain prescription pharmaceuticals. Certain herbs recently introduced into the U.S. market may not have been previously tested adequately for purity, safety, and efficacy. Due to the lack of reliable clinical data regarding the safe use of various herbal products currently available, the public should be made aware regarding the possible health hazards of using certain herbs for therapeutic purposes. The potentially fatal toxicity of yellow oleander seed is confirmed by cases reported from various countries, while the purported benefits of using it for weight loss have not been evaluated by any known clinical trials. For this reason, the use of yellow oleander seed as a dietary supplement should be avoided.

Short-Term E-Cigarette Exposure Increases the Risk of Thrombogenesis and Enhances Platelet Function in Mice.

BACKGROUND: Cardiovascular disease is the main cause of death in the United States, with smoking being the primary preventable cause of premature death, and thrombosis being the main mechanism of cardiovascular mortality in smokers. Due to the perception that electronic/e-cigarettes are "safer/less harmful" than conventional cigarettes, their usage-among a variety of ages-has increased tremendously during the past decade. Notably, there are limited studies regarding the negative effects of e-cigarettes on the cardiovascular system, which is also the subject of significant debate. METHODS AND RESULTS: We employed a passive e-VapeTM vapor inhalation system and developed an in vivo whole-body e-cigarette mouse exposure protocol that mimics real-life human exposure scenarios/conditions and investigated the effects of e-cigarettes and clean air on platelet function and thrombogenesis. Our results show that platelets from e-cigarette-exposed mice are hyperactive, with enhanced aggregation, dense and α granule secretion, activation of the αIIbß3 integrin, phosphatidylserine expression, and Akt and ERK activation, when compared with clean air-exposed platelets. E-cigarette-exposed platelets were also found to be resistant to inhibition by prostacyclin, relative to clean air. Furthermore, the e-cigarette-exposed mice exhibited a shortened thrombosis occlusion and bleeding times. CONCLUSIONS: Taken together, our data demonstrate for the first time that e-cigarettes alter physiological hemostasis and increase the risk of thrombogenic events. This is attributable, at least in part, to the hyperactive state of platelets. Thus, the negative health consequences of e-cigarette exposure should not be underestimated and warrant further investigation.

Providers of herbal products in the largest US-Mexico border community.

We surveyed providers of herbal products in El Paso, Texas, and Ciudad Juárez, México, to find out which herbal products they used, the content and place of origin of the products, and the illnesses for which the products were recommended. Providers were selected randomly from Ciudad Juárez and El Paso. Most of the herbal products sold in El Paso (98%) are from the United States, whereas most sold in Ciudad Juárez (89.6%) are from México. People in El Paso tend to consume herbal or natural supplements for weight loss or muscle enhancement; those in Ciudad Juárez use herbal products (mostly crude plants) to treat specific illnesses. Ciudad Juárez and El Paso are bordering cities; however, the herbal products consumed by their respective populations are distinct, both in content and method of use.

Guide for herbal product use by Mexican Americans in the largest Texas-Mexico border community.

Use of herbal products is a very common practice among Mexican Americans living in the El Paso, Texas, region. Although medicinal plants are generally assumed to be a safe and natural alternative to conventional medications, some herbal products could pose a potential health risk to the consumer. Currently, only a few studies focus on herbal product use by Mexican Americans, and no studies have focused on its use by patients with human immunodeficiency virus (HN) living on the US-Mexico border. A prospective observational study was conducted in 439 non-HIV patients, as well as in 35 patients suffering from HIV Findings showed that 347 out of 439 (79%) of non-HIV patients and 25 out of 35 (71%) of HIV patients reported using herbal products.

Comparison of a Medication Inventory and a Dietary Supplement Interview in Assessing Dietary Supplement Use in the Hispanic Community Health Study/Study of Latinos.

Although dietary supplement use is common, its assessment is challenging, especially among ethnic minority populations such as Hispanics/Latinos. Using the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) (n = 16,415), this report compares two strategies for capturing dietary supplement use over a 30-day period: a medication-based inventory and a nutrition-based dietary supplement interview. Age-standardized prevalence was calculated across multiple dietary supplement definitions, adjusted with survey/nonresponse weights. The prevalence of dietary supplement use was substantially higher as measured in the dietary supplement interview, compared to the medication inventory: for total dietary supplements (39% vs 26%, respectively), for nonvitamin, nonmineral supplements (24% vs 12%), and for botanicals (9.2% vs 4.5%). Concordance between the two assessments was fair to moderate (Cohen's kappa: 0.31-0.52). Among women, inclusion of botanical teas increased the prevalence of botanical supplement use from 7% to 15%. Supplement assessment that includes queries about botanical teas yields more information about patient supplement use.

Herbal product use by hispanic surgical patients.

We hypothesized that the use of herbal products is highly prevalent in Hispanic surgical patients on both sides of the U.S./México border. One hundred fifteen patients were interviewed in El Paso and 112 in Ciudad Juárez from December 2001 to June 2002. This prospective, randomized study evaluated patients aged 18 years or older that were scheduled for surgery. Sixty-two per cent of our sample in the United States and 81 per cent of patients in Mexico reported using herbal products in the past year. About 58 per cent of patients in the United States and 49 per cent in Mexico rated the products as "excellent" in treating their conditions. Ninety-two percent of U.S, and 93 per cent of Mexican patients did not inform their physician of their herbal use. Preoperative assessment of patients did not include inquiries about herbal products in either hospital. With the growing use of herbal products and because most users do not inform their physician, there is increasing concern related to the possible occurrence of herbal-related adverse events during and after surgery. The fact that health care personnel did not inquire about herbal product use before surgery is an added concern.

Herbal product use in non-HIV and HIV-positive Hispanic patients.

PURPOSE: The primary endpoint of this study was to determine the prevalence of herbal product use by a sample of Mexican-American patients in the El Paso, TX region. Even though medicinal plants are popularly assumed to be a safe and natural alternative to conventional medications, some herbal products may pose a potential health risk to the consumer. Currently, there are few studies related to herbal use by Mexican Americans and none in HIV patients living on the U.S./México border. METHODS: A prospective observational study was conducted in hospitals and clinics throughout the El Paso region area. A semistructured interview was conducted by trained bilingual interviewers. A 45-item bilingual questionnaire was used to collect the information. RESULTS: A total of 439 non-HIV patients as well as 35 patients afflicted with HIV participated in the study. Seventy-nine percent (347/439) of non-HIV and 71% (25/35) of HIV patients reported using herbal products. The percentages of herbal use among the two groups did not show any statistically significant differences (p=0.29), and both groups reflected that herbal products are commonly used. CONCLUSIONS: The use of herbal products was very common among non-HIV (79%) and HIV-positive (71%) Mexican-Americans patients in the El Paso region.
