Abstract
HPV vaccination rates remain below target levels among adolescents in the United States, which is particularly concerning in safety-net populations with persistent disparities in HPV-associated cancer burden. Perspectives on evidence-based strategies (EBS) for HPV vaccination among key implementation participants, internal and external to clinics, can provide a better understanding of why these disparities persist. We conducted virtual interviews and focus groups, guided by the Practice Change Model, with clinic members (providers, clinic leaders, and clinic staff) and community members (advocates, parents, policy-level, and payers) in Los Angeles and New Jersey to understand common and divergent perspectives on and experiences with HPV vaccination in safety-net primary care settings. Fifty-eight interviews and seven focus groups were conducted (n = 65 total). Clinic members (clinic leaders n = 7, providers n = 12, and clinic staff n = 6) revealed conflicting HPV vaccine messaging, lack of shared motivation to reduce missed opportunities and improve workflows, and non-operability between clinic electronic health records and state immunization registries created barriers for implementing effective strategies. Community members (advocates n = 8, policy n = 11, payers n = 8, and parents n = 13) described lack of HPV vaccine prioritization among payers, a reliance on advocates to lead national agenda setting and facilitate local implementation, and opportunities to support and engage schools in HPV vaccine messaging and adolescents in HPV vaccine decision-making. Participants indicated the COVID-19 pandemic complicated prioritization of HPV vaccination but also created opportunities for change. These findings highlight design and selection criteria for identifying and implementing EBS (changing the intervention itself, or practice-level resources versus external motivators) that bring internal and external clinic partners together for targeted approaches that account for local needs in improving HPV vaccine uptake within safety-net settings.

Understanding medical mistrust and HPV vaccine hesitancy among multiethnic parents in Los Angeles. J Behav Med 2023; 46:100-115. [PMID: 35107656 PMCID: PMC8808279 DOI: 10.1007/s10865-022-00283-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 01/03/2022] [Indexed: 01/26/2023]
Abstract
Determinants of parental HPV vaccine hesitancy, including medical mistrust and exposure to negative vaccine information, are understudied in racial/ethnic minority communities where vaccine uptake is low. We conducted a cross-sectional survey (March 2021) among parents of adolescents, ages 9-17 years, from an academic enrichment program serving low-income, first-generation, underrepresented minority families in Los Angeles to understand determinants of parental HPV vaccine hesitancy. Parents completed self-administered surveys, including a 9-item HPV vaccine hesitancy scale, in either English, Spanish, or Chinese. Logistic regression was used to identify individual and interpersonal factors associated with parental hesitancy and adolescent HPV vaccination. One-fifth of parents (n = 357) reported high HPV vaccine hesitancy and > 50% reported concerns about safety or side effects. High medical mistrust was associated with high parental HPV vaccine hesitancy (adjusted-OR 1.69, 95% CI: 1.13, 2.37). Community-tailored and multilevel strategies to increase vaccine confidence are needed to improve HPV and other adolescent vaccinations.

Abstract
BACKGROUND Human papillomavirus (HPV) vaccine hesitancy is a growing concern in the United States, yet understudied among racial/ethnic minority parents. We conducted qualitative research to understand parental HPV vaccine hesitancy and inform community-specific, multilevel approaches to improve HPV vaccination among diverse populations in Los Angeles. METHODS We recruited American Indian/Alaska Native (AI/AN), Hispanic/Latino/a (HL) and Chinese parents of unvaccinated children (9-17 years) from low-HPV vaccine uptake regions in Los Angeles for virtual focus groups (FGs). FGs were conducted in English (2), Mandarin (1), and Spanish (1) between June-August 2021. One English FG was with AI/AN-identifying parents. FGs prompted discussions about vaccine knowledge, sources of information/hesitancy, logistical barriers and interpersonal, healthcare and community interactions regarding HPV vaccination. Guided by the social-ecological model, we identified multilevel emergent themes related to HPV vaccination. RESULTS Parents (n = 20) in all FGs reported exposure to HPV vaccine information from the internet and other sources, including in-language media (Mandarin) and health care providers (Spanish). All FGs expressed confusion around the vaccine and had encountered HPV vaccine misinformation. FGs experienced challenges navigating relationships with children, providers, and friends/family for HPV vaccine decision-making. At the community-level, historical events contributed to mistrust (e.g., forced community displacement [AI/AN]). At the societal-level, transportation, and work schedules (Spanish, AI/AN) were barriers to vaccination. Medical mistrust contributed to HPV vaccine hesitancy across the analysis levels. CONCLUSION Our findings highlight the importance of multilevel influences on parental HPV vaccine hesitancy and decision-making and the need for community-specific messaging to combat medical mistrust and other barriers to HPV vaccination among racial/ethnic minority communities.

Abstract
Abstract
Background: Higher cervical cancer incidence rates among subgroups of Asian American Native Hawaiian Pacific Islander (AANHPI) women are often overlooked in studies that aggregate this extremely heterogeneous population. There is a need to geographically target ethnic subgroup communities with the highest needs with culturally responsive services for cancer prevention. We analyzed the distribution of cervical cancer clusters among the ethnic subgroups of AANHPI women in Los Angeles County. Methods: We included data for first primary cancer cases with any stage of cervical cancer (only malignant tumors) diagnosed from 2000 to 2018 among AANHPI from the Los Angeles County Cancer Surveillance Program. We performed hotspot analyses using the Getis-Ord GI*statistic in ArcGIS to compare the distribution of statistically significant clusters of cervical cancer cases in Los Angeles County using a fixed band. Hot and cold spots with less than 11 cases were suppressed to protect patient confidentiality. Results: Among 8,708 cases of cervical cancer, AANHPI population accounted for 1332 cases (15%). Among the AANHPI population, the three most prevalent ethnic groups were Filipino (n=364, 28%), Chinese (n=314, 24%), and Korean (n=232, 18%) Americans. The hotspots varied by ethnic subgroups and emerged in areas with high proportions of Filipino (Glendale/Carson), Chinese (Arcadia/El Monte), and Korean (Hollywood Hills) American residents, respectively. Discussion: Our findings geospatially disaggregate the cervical cancer prevalence among AANHPI population in Los Angeles County by ethnic subgroups. Specifically, the cervical cancer hotspots contextualize potential geographic- and area-level factors that affect access to preventive services for these vulnerable populations and can facilitate allocating resources for culturally responsive services to increase uptake of HPV vaccination and screening.

Abstract
BACKGROUND Oral microorganisms produce damage through the transfer to bloodstream, colonizing other tissues or direct damage in the oral cavity. Aim to study the quantitative interactions between C. albicans and the mutans streptococci and ms serotypes in the saliva of the oral cavity of patients with Down syndrome (DS). MATERIAL AND METHODS Included 120 patients of both genders, 60 patients with Down syndrome (DS) and 60 pa- tients as a control group (CG). Samples of saliva were taken, and bacteria and fungi were grown on TYCSB and Saboureaud agar. Microbiological, serological and quantitative analyses were performed to determine the kind of isolated of microorganisms corresponding to the ms c, e, f and k for species S. mutans and d and g for S. sobrinus and C. albicans. Electronic scanning microscopy was employed to visualize and confirm the colonies under study. Statistics analysis included t-test proofs for matched data test, Scheffé and ANOVA. RESULTS Forming units (CFU) per mL of saliva of C. albicans a significant difference was observed among DS<CG groups. A correlation of the C. albicans quantity and the ms count was found by age intervals however, tendencies were different in SD and CG. Also, the CFU of C. albicans was different among the serotypes of ms (c, e, f, k <d, g, h, <notyped). CONCLUSIONS These results show a significant non-random association between these two commensal microorganisms in different patient groups.

Abstract
Advances in genetics and genomics have revolutionized the treatment possibilities for common diseases. Many treatment prospects demonstrate promise for addressing population health disparities. African-American nurses have a crucial role in facilitating the translation of scientific discovery into real-world practice among at-risk populations. The primary aims of this pilot study were to gain insight into the contextual perspectives of African-American nurses' views about factors that impede, support, and/or promote genetics and genomics knowledge in practice and participation in research. Data were obtained from a focused discussion of N = 6 registered nurses who attended the 2011 National Black Nurses Association (NBNA) annual conference. Utilizing a grounded theory approach, themes extrapolated from the focused discussion included the need for genetic and genomic education, distrust, cultural competency in care interactions, and the role of the NBNA in providing education. Suggestions for explanatory relationships are also presented.

Abstract
The Coleman Care Transitions Intervention (CTI) is a "Patient Activation Model." Depression can be a barrier to activation and may challenge CTI. This study addressed whether CTI coaches modified the intervention for older adults who screened positive for depression. Over 4,500 clients in a Centers for Medicare and Medicaid Services demonstration completed screening for depression with the PHQ-9; one in five screened positive (score = 9+). Our findings suggest that coaches modified CTI and played a more directive role for clients who screened positive for depression, resulting in similar 30-day readmission rates among patients who screened positive for depression risk and those who did not. That finding stands in contrast to the widely reported higher readmission rates among people screening positive for depression.

Abstract
Como consecuencia de los cambios en la normativa europea sobre bienestar animal, en un futuro próximo la industria porcina podría afrontar la prohibición de la castración de lechones machos, lo que implicaría un riesgo medio o alto de obtener carne con olor sexual. La castración física afecta a la cantidad de grasa de depósito y a la composición de ácidos grasos de los tejidos magro y graso. Por lo tanto, el uso de cerdos enteros en la industria podría afectar al procesado y a la calidad de los productos cárnicos. El objetivo de este estudio fue evaluar el efecto del nivel de androstenona (AND) en las características de un embutido crudo curado (chorizos). Para ello, se analizó la composición química, el perfil de ácidos grasos y las características sensoriales de chorizos de cerdos castrados y de cerdos machos enteros con dos niveles de AND (Medio: 0,5-0,8 µg/g de grasa, Alto: 1,1-2,9 µg/g de grasa). Los chorizos procedentes de cerdos con niveles de AND medio y alto presentaron el mayor contenido en proteína y el menor contenido de grasa (P

Abstract
BACKGROUND Few studies have examined inflammatory bowel disease (IBD) patients' knowledge and understanding of biologic therapies outside traditional surveys. Here, we used social media data to examine IBD patients' understanding of the risks and benefits associated with biologic therapies and how this affects decision-making. METHODS We collected posts from Twitter and e-forum discussions from >3000 social media sites posted between June 27, 2012 and June 27, 2015. Guided by natural language processing, we identified posts with specific IBD keywords that discussed the risks and/or benefits of biologics. We then manually coded the resulting posts and performed qualitative analysis using ATLAS.ti software. A hierarchical coding structure was developed based on the keyword list and relevant themes were identified through manual coding. RESULTS We examined 1598 IBD-related posts, of which 452 (28.3%) centered on the risks and/or benefits of biologics. There were 5 main themes: negative experiences and concerns with biologics (n = 247; 54.6%), decision-making surrounding biologic use (n = 169; 37.4%), positive experiences with biologics (n = 168; 37.2%), information seeking from peers (n = 125; 27.7%), and cost (n = 38; 8.4%). Posts describing negative experiences primarily commented on side effects from biologics, concerns about potential side effects and increased cancer risk, and pregnancy safety concerns. Posts on decision-making focused on nonbiologic treatment options, hesitation to initiate biologics, and concerns about changing or discontinuing regimens. CONCLUSIONS Social media reveals a wide range of themes governing patients' experience and choice with IBD biologics. The complexity of navigating their risk-benefit profiles suggests merit in creating online tailored decision tools to support IBD patients' decision-making with biologic therapies.

Abstract
The objective of this study was to determine, in patients with active unilateral condylar hyperplasia, which is the most reliable point to measure the length of the condylar unit: from the sigmoid notch or from the mandibular lingula to the condylar head. On cone beam computed tomography, an observational cross-sectional study was designed for 20 patients with active unilateral condylar hyperplasia. We measured and compared ramus length (affected and healthy sides) and condylar length (measured from the mandibular lingula and from the mandibular sigmoid notch) on both sides. The average of all the differences in ramus height (D.1) was 7.97mm; the average of all the differences in condylar heights measured from mandibular lingula (D.2) was 7.16mm, and measured from the sigmoid notch (D.3) was 4.89mm. No significant difference between D.1 and D.2 (P=0.818). There was a significant difference between D.1 and D.3 (P=0.005) and between D.2 and D.3 (P=0.0005). It can be concluded that the mandibular lingula is the lowest point of the condylar skeletal unit and is therefore a stable parameter to be used in patients with condylar hyperplasia. On the other hand, the sigmoidal notch is not a stable parameter in patients with asymmetry due to condylar hyperplasia.

Abstract
BACKGROUND Improvements in software and design and reduction in cost have made virtual reality (VR) a practical tool for immersive, three-dimensional (3D), multisensory experiences that distract patients from painful stimuli. OBJECTIVE The objective of the study was to measure the impact of a onetime 3D VR intervention versus a two-dimensional (2D) distraction video for pain in hospitalized patients. METHODS We conducted a comparative cohort study in a large, urban teaching hospital in medical inpatients with an average pain score of ≥3/10 from any cause. Patients with nausea, vomiting, dementia, motion sickness, stroke, seizure, and epilepsy and those placed in isolation were excluded. Patients in the intervention cohort viewed a 3D VR experience designed to reduce pain using the Samsung Gear Oculus VR headset; control patients viewed a high-definition, 2D nature video on a 14-inch bedside screen. Pre- and postintervention pain scores were recorded. Difference-in-difference scores and the proportion achieving a half standard deviation pain response were compared between groups. RESULTS There were 50 subjects per cohort (N=100). The mean pain reduction in the VR cohort was greater than in controls (-1.3 vs -0.6 points, respectively; P=.008). A total of 35 (65%) patients in the VR cohort achieved a pain response versus 40% of controls (P=.01; number needed to treat=4). No adverse events were reported from VR. CONCLUSIONS Use of VR in hospitalized patients significantly reduces pain versus a control distraction condition. These results indicate that VR is an effective and safe adjunctive therapy for pain management in the acute inpatient setting; future randomized trials should confirm benefit with different visualizations and exposure periods.

Abstract
OBJECTIVES The National Institutes of Health (NIH) created the Patient Reported Outcomes Measurement Information System (PROMIS) to allow efficient, online measurement of patient-reported outcomes (PROs), but it remains untested whether PROMIS improves outcomes. Here, we aimed to compare the impact of gastrointestinal (GI) PROMIS measures vs. usual care on patient outcomes. METHODS We performed a pragmatic clinical trial with an off-on study design alternating weekly between intervention (GI PROMIS) and control arms at one Veterans Affairs and three university-affiliated specialty clinics. Adults with GI symptoms were eligible. Intervention patients completed GI PROMIS symptom questionnaires on an e-portal 1 week before their visit; PROs were available for review by patients and their providers before and during the clinic visit. Usual care patients were managed according to customary practices. Our primary outcome was patient satisfaction as determined by the Consumer Assessment of Healthcare Providers and Systems questionnaire. Secondary outcomes included provider interpersonal skills (Doctors' Interpersonal Skills Questionnaire (DISQ)) and shared decision-making (9-item Shared Decision Making Questionnaire (SDM-Q-9)). RESULTS There were 217 and 154 patients in the GI PROMIS and control arms, respectively. Patient satisfaction was similar between groups (P>0.05). Intervention patients had similar assessments of their providers' interpersonal skills (DISQ 89.4±11.7 vs. 89.8±16.0, P=0.79) and shared decision-making (SDM-Q-9 79.3±12.4 vs. 79.0±22.0, P=0.85) vs. CONCLUSIONS This is the first controlled trial examining the impact of NIH PROMIS in clinical practice. One-time use of GI PROMIS did not improve patient satisfaction or assessment of provider interpersonal skills and shared decision-making. Future studies examining how to optimize PROs in clinical practice are encouraged before widespread adoption.

Abstract
BACKGROUND Virtual reality (VR) offers immersive, realistic, three-dimensional experiences that "transport" users to novel environments. Because VR is effective for acute pain and anxiety, it may have benefits for hospitalized patients; however, there are few reports using VR in this setting. OBJECTIVE The aim was to evaluate the acceptability and feasibility of VR in a diverse cohort of hospitalized patients. METHODS We assessed the acceptability and feasibility of VR in a cohort of patients admitted to an inpatient hospitalist service over a 4-month period. We excluded patients with motion sickness, stroke, seizure, dementia, nausea, and in isolation. Eligible patients viewed VR experiences (eg, ocean exploration; Cirque du Soleil; tour of Iceland) with Samsung Gear VR goggles. We then conducted semistructured patient interview and performed statistical testing to compare patients willing versus unwilling to use VR. RESULTS We evaluated 510 patients; 423 were excluded and 57 refused to participate, leaving 30 participants. Patients willing versus unwilling to use VR were younger (mean 49.1, SD 17.4 years vs mean 60.2, SD 17.7 years; P=.01); there were no differences by sex, race, or ethnicity. Among users, most reported a positive experience and indicated that VR could improve pain and anxiety, although many felt the goggles were uncomfortable. CONCLUSIONS Most inpatient users of VR described the experience as pleasant and capable of reducing pain and anxiety. However, few hospitalized patients in this "real-world" series were both eligible and willing to use VR. Consistent with the "digital divide" for emerging technologies, younger patients were more willing to participate. Future research should evaluate the impact of VR on clinical and resource outcomes.

Postoperative Gastrointestinal Telemetry with an Acoustic Biosensor Predicts Ileus vs. Uneventful GI Recovery. J Gastrointest Surg 2016; 20:132-9; discussion 139. [PMID: 26408329 DOI: 10.1007/s11605-015-2956-3] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2015] [Accepted: 09/14/2015] [Indexed: 01/31/2023]
Abstract
BACKGROUND Postoperative ileus (POI) can worsen outcomes, increase cost, and prolong hospitalization. We previously found that a disposable, non-invasive acoustic gastrointestinal surveillance (AGIS) biosensor distinguishes healthy controls from patients recovering from abdominal surgery. Here, we tested whether AGIS can prospectively predict which patients will develop POI in a multicenter study. STUDY DESIGN AGIS is a disposable device embedded with a microphone that adheres to the abdominal wall and connects to a computer that measures acoustic intestinal rate (IR), defined as motility events/minute. We applied AGIS for 60 min before and continuously after abdominal surgery. Clinicians blinded to AGIS recordings clinically separated patients into those with vs. without POI. We used receiver operating characteristic curve analysis to calculate sensitivity, specificity, and negative predictive value (NPV) of AGIS to predict POI. RESULTS There were 28 subjects; nine developed POI. Median IR was 3.01/min and 4.46/min between POI and non-POI groups, respectively (P = 0.03). AGIS predicted POI onset with a sensitivity, specificity, and NPV of 63, 72, and 81%, respectively. CONCLUSION Non-invasive, abdominal, acoustic monitoring prospectively predicts POI. Surgeons may use AGIS to rule out POI with over 80% certainty; this offers added confidence to advance feeding earlier in those for whom it is safe.

Preventing patient absenteeism: validation of a predictive overbooking model. THE AMERICAN JOURNAL OF MANAGED CARE 2015; 21:902-910.

Abstract
OBJECTIVES To develop a model that identifies patients at high risk for missing scheduled appointments ("no-shows" and cancellations) and to project the impact of predictive overbooking in a gastrointestinal endoscopy clinic-an exemplar resource-intensive environment with a high no-show rate. STUDY DESIGN We retrospectively developed an algorithm that uses electronic health record (EHR) data to identify patients who do not show up to their appointments. Next, we prospectively validated the algorithm at a Veterans Administration healthcare network clinic. METHODS We constructed a multivariable logistic regression model that assigned a no-show risk score optimized by receiver operating characteristic curve analysis. Based on these scores, we created a calendar of projected open slots to offer to patients and compared the daily performance of predictive overbooking with fixed overbooking and typical "1 patient, 1 slot" scheduling. RESULTS Data from 1392 patients identified several predictors of no-show, including previous absenteeism, comorbid disease burden, and current diagnoses of mood and substance use disorders. The model correctly classified most patients during the development (area under the curve [AUC] = 0.80) and validation phases (AUC = 0.75). Prospective testing in 1197 patients found that predictive overbooking averaged 0.51 unused appointments per day versus 6.18 for typical booking (difference = -5.67; 95% CI, -6.48 to -4.87; P < .0001). Predictive overbooking could have increased service utilization from 62% to 97% of capacity, with only rare clinic overflows. CONCLUSIONS Information from EHRs can accurately predict whether patients will no-show. This method can be used to overbook appointments, thereby maximizing service utilization while staying within clinic capacity.

Computer versus physician identification of gastrointestinal alarm features. Int J Med Inform 2015; 84:1111-7. [PMID: 26254875 DOI: 10.1016/j.ijmedinf.2015.07.006] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2015] [Revised: 07/14/2015] [Accepted: 07/14/2015] [Indexed: 12/27/2022]
Abstract
OBJECTIVE It is important for clinicians to inquire about "alarm features" as it may identify those at risk for organic disease and who require additional diagnostic workup. We developed a computer algorithm called Automated Evaluation of Gastrointestinal Symptoms (AEGIS) that systematically collects patient gastrointestinal (GI) symptoms and alarm features, and then "translates" the information into a history of present illness (HPI). Our study's objective was to compare the number of alarms documented by physicians during usual care vs. that collected by AEGIS. METHODS We performed a cross-sectional study with a paired sample design among patients visiting adult GI clinics. Participants first received usual care by their physicians and then completed AEGIS. Each individual thus contributed both a physician-documented and computer-generated HPI. Blinded physician reviewers enumerated the positive alarm features (hematochezia, melena, hematemesis, unintentional weight loss, decreased appetite, and fevers) mentioned in each HPI. We compared the number of documented alarms within patient using the Wilcoxon signed-rank test. RESULTS Seventy-five patients had both physician and AEGIS HPIs. AEGIS identified more patients with positive alarm features compared to physicians (53% vs. 27%; p<.001). AEGIS also documented more positive alarms (median 1, interquartile range [IQR] 0-2) vs. physicians (median 0, IQR 0-1; p<.001). Moreover, clinicians documented only 30% of the positive alarms self-reported by patients through AEGIS. CONCLUSIONS Physicians documented less than one-third of red flags reported by patients through a computer algorithm. These data indicate that physicians may under report alarm features and that computerized "checklists" could complement standard HPIs to bolster clinical care.

Abstract
OBJECTIVES Healthcare delivery now mandates shorter visits with higher documentation requirements, undermining the patient-provider interaction. To improve clinic visit efficiency, we developed a patient-provider portal that systematically collects patient symptoms using a computer algorithm called Automated Evaluation of Gastrointestinal Symptoms (AEGIS). AEGIS also automatically "translates" the patient report into a full narrative history of present illness (HPI). We aimed to compare the quality of computer-generated vs. physician-documented HPIs. METHODS We performed a cross-sectional study with a paired sample design among individuals visiting outpatient adult gastrointestinal (GI) clinics for evaluation of active GI symptoms. Participants first underwent usual care and then subsequently completed AEGIS. Each individual thereby had both a physician-documented and a computer-generated HPI. Forty-eight blinded physicians assessed HPI quality across six domains using 5-point scales: (i) overall impression, (ii) thoroughness, (iii) usefulness, (iv) organization, (v) succinctness, and (vi) comprehensibility. We compared HPI scores within patient using a repeated measures model. RESULTS Seventy-five patients had both computer-generated and physician-documented HPIs. The mean overall impression score for computer-generated HPIs was higher than physician HPIs (3.68 vs. 2.80; P<0.001), even after adjusting for physician and visit type, location, mode of transcription, and demographics. Computer-generated HPIs were also judged more complete (3.70 vs. 2.73; P<0.001), more useful (3.82 vs. 3.04; P<0.001), better organized (3.66 vs. 2.80; P<0.001), more succinct (3.55 vs. 3.17; P<0.001), and more comprehensible (3.66 vs. 2.97; P<0.001). CONCLUSIONS Computer-generated HPIs were of higher overall quality, better organized, and more succinct, comprehensible, complete, and useful compared with HPIs written by physicians during usual care in GI clinics.

Abstract
During 2000 to 2009, data on people undergoing HIV testing and on those newly diagnosed with HIV were collected in a network of 20 Spanish clinics specialising in sexually transmitted infections and/or HIV testing and counselling. The number of tests performed, overall and disaggregated by different variables, was obtained. HIV prevalence among first-time testers and HIV incidence among repeat testers were calculated. To evaluate trends, joinpoint regression models were fitted. In total, 236,939 HIV tests were performed for 165,745 individuals. Overall HIV prevalence among persons seeking HIV testing was 2.5% (95% CI: 2.4 to 2.6). Prevalence was highest in male sex workers who had sex with other men (19.0% (95% CI: 16.7 to 21.4)) and was lowest in female sex workers (0.8% (95% CI: 0.7 to 0.9)). Significant trends in prevalence were observed in men who have sex with men (MSM) (increasing) and heterosexual individuals (decreasing). The incidence analysis included 30,679 persons, 64,104 person-years (py) of follow-up and 642 seroconversions. The overall incidence rate (IR) was 1.0/100 py (95% CI: 0.9/100 to 1.1/100). Incidence was significantly higher in men and transgender females than in women (1.8/100 py (95% CI: 1.6 to 1.9), 1.2/100 py (95% CI: 0.5 to 2.8) and 0.1/100 py (95% CI: 0.09 to 0.2) respectively) and increased with age until 35–39 years. IRs in MSM and people who inject drugs were significantly greater than in heterosexual individuals (2.5/100 py (95% CI: 2.3 to 2.7), 1.6/100 py (95% CI: 1.1 to 2.2) and 0.1/100 py (95% CI: 0.09 to 0.2) respectively), and an upward trend was observed in MSM. Our results call for HIV prevention to be reinforced in MSM and transgender women in Spain.

Abstract
OBJECTIVES Gait and movement abnormalities are traditionally considered infrequent in patients with mild/moderate Alzheimer's disease (AD). However, an increased risk of falls and gait abnormalities has been detected, even in early stages of the disease. Whether these abnormalities are associated with cerebrovascular disease, which has a high prevalence in AD, remains unclear. DESIGN Cross-sectional study. SETTING Dementia outpatient clinics. PARTICIPANTS 24 mild/moderate AD patients with (AD+CVD) and 20 without (AD-CVD) cerebrovascular disease without a history of stroke and antipsychotic medications. MEASUREMENTS Physical performance, measured with the short physical performance battery [SPPB], a summary measure combining 4-meter gait speed, balance and muscle strength, and with 8-meter gait speed with a turn was compared between the two groups. RESULTS AD+CVD patients showed a significant higher prevalence of 4-meter gait speed slower than 0.8 m/s (37.5% vs. 5%, p-value=0.01) and balance impairment (37.5% vs. 10%, p-value=0.038), as well as a slower 8-meter gait speed with a turn (mean+SD=0.6±0.2 vs. 0.8±0.2, p-value=0.024). These associations were confirmed in multivariable models. No differences were observed for muscle strength. CONCLUSION In our sample, AD with cerebrovascular disease had worse gait and balance than AD without cerebrovascular disease. If confirmed, these results may have clinical implications, since cerebrovascular disease can be potentially prevented.

Abstract
AIM Furosemide test is a simple and useful test of renal physiology usually used for evaluating the capability of the collecting ducts to secrete potassium under the effect of this drug. Its behaviour pattern has already been established in healthy children, young, and old people, as well as in stage III-chronic kidney disease (III-CKD) patients. However, its behaviour has not been described in kidney transplant patients yet, which we explored in this study. MATERIALS AND METHODS Twenty young volunteers on a standard western diet (50 mmol of potassium/day) were studied: Ten were III-CKD and the rest were kidney transplant (KT) patients on FK. Before, while the test was being carried out, and 180 min after a single dose of intravenous furosemide (1 mg/kg), urine and blood samples were obtained, for creatinine and potassium levels. From these data, we calculated fractional excretion of potassium (FEK). Statistical analysis was performed applying Wilcoxon test. RESULTS There was a significant difference regarding pre-furosemide (basal) FE of potassium between the III-CKD and KT groups 16 ± 5 (III-CKD) versus 7 ± 5 (KT), p = 0.008. Regarding the post-furosemide, peak FEK was significantly lower in the KT group (15 ± 11 %) compared to the III-CKD ones (49.8 ± 9 %, p = 0.01). In both groups, the peak FEK post-furosemide was reached later (120 min) compared to the conventional test (30 min). CONCLUSION Furosemide test showed significantly lower basal and post-furosemide peak FEK values in KT patients on tacrolimus compared with stage III-chronic renal disease.

Abstract
Cheese may be manufactured in the United States using raw milk, provided the cheese is aged for at least 60 days at temperatures not less than 35°F (1.7°C). There is now increased concern among regulators regarding the safety of raw milk cheese due to the potential ability of foodborne pathogens to survive the manufacturing and aging processes. In this study, 41 raw milk cheeses were obtained from retail specialty shops, farmers' markets, and on-line sources. The cheeses were then analyzed for the presence of Listeria monocytogenes, Salmonella, Escherichia coli O157:H7, Staphylococcus aureus, and Campylobacter. Aerobic plate counts (APC), coliform and yeast/mold counts were also performed. The results revealed that none of the enteric pathogens were detected in any of the samples tested. Five samples contained coliforms; two of those contained E. coli at less than 10(2) cfu/g. Three other cheese samples contained S. aureus. The APC and yeast-mold counts were within expected ranges. Based on the results obtained from these 41 raw milk cheeses, the 60-day aging rule for unpasteurized milk cheeses appears adequate for producing microbiologically safe products.

Abstract
Cypress needles collected at the edge of the Malvési uranium facility (SW France) exhibit enhanced activities of actinides and some decay products (uranium, americium, plutonium, (230)Th, (226)Ra) compared to a remote site. These enhanced activities resulted from the release of U via smokestacks and passive release from former artificial ponds located inside the nuclear site. Enhanced activities are also observed in selected produce (wheat, lettuce, fruits) sampled from the edge of the site. However, excess actinides measured in wheat grains in 2007 are inconsistent with the activities and the uranium ratio measured in the soils. This result suggests that the studied annual crops were contaminated mainly through the short-term release of airborne actinides, and that other transfer pathways, such as, uptake through the roots or adhesion of soil particles, were negligible.

Abstract
Uranium and plutonium isotopes were measured in soils, sediments and waters in an area subject to the past and present discharges from the uranium conversion plant of Malvési (France). The isotopes (236)U and (239)Pu are well known activation products of uranium and they prove to be powerful tracers of spent fuel releases in soils and sediments. On the other hand (234)U and (238)U activities measured in waters can be used to distinguish between releases and background uranium sources. Such findings contribute to improve the monitoring of the actinides releases by nuclear fuel facilities (mining sites, conversion, enrichment and fuel plants, reprocessing plants).

Abstract
INTRODUCTION Decline in glomerular filtration rate (GFR) is one of several changes in renal physiology in the elderly. Renal reserve (RR) is the kidney's capacity to increase its basal GFR by at least 20% after a protein overload. Even though it has already been reported that RR is preserved in healthy old people, there is no information whether RR is also preserved in the healthy very old one (older than 74 of age), which we decided to study and report our findings in this paper. MATERIAL AND METHOD We studied RR in 16 healthy persons divided into three age groups: young: 20-40 years old (n: 5): 64-74 years old (n: 6) and oldest old: >74 years old (n: 5). Renal reserve test was performed by assessing creatinine clearance with cimetidine before and after an oral protein load. Statistical analysis was performed using ANOVA test. RESULTS Even though renal reserve response was present in all age groups, its magnitude (delta GFR) was significantly higher in the healthy young group (103.6 ± 53 ml/min) compared to the old one (34.1 ± 40 ml/min) (P = 0.002), while it was significantly lower in the healthy oldest old (20.7 ± 0.7 ml/min) group compared to the other two groups (P = 0.002). CONCLUSION Renal reserve is preserved in healthy very old people, but its magnitude decreases significantly with age.

Abstract
Chronic dialysis is a valid therapeutic option in very elderly ESRD patients, even though the decision to dialyze or not has little impact on survival. Additionally, very old patients usually do not agree with starting chronic dialysis. Even though, activated charcoal is a cheap treatment for working as adsorbent for nitrogenous products its utility is very limited. We studied the combination of a low protein diet and oral activated charcoal to reduce serum urea and creatinine levels in very old ESRD patients who had refused to start chronic dialysis. Nine lucid, very old > 80 years, ESRD patients who had refused to start dialysis were prescribed a treatment based on a combination of a very low protein diet and oral activated charcoal (30 gram/day). None of the patients had anuria, oliguria, edema, significant metabolic acidosis or hyperkalemia. None of them had significant gastrointestinal symptoms. After one week and ten months of charcoal use significant decrease in blood urea and creatinine levels was observed and none of them required emergency dialysis during this time. In conclusion, in patients more than 80 years of age low protein diet and oral activated charcoal may control the uremic symptoms effectively.

Abstract
The presence of Salmonella was determined in 116 samples of poultry meat, 81 samples of pork, 73 samples of beef, 33 samples of cheese, 61 samples of fish, and 78 samples of vegetables collected from retail stores and supermarkets in Hidalgo State (Mexico). Ninety-three Salmonella strains isolated from raw foods were characterized, and MICs were determined for 10 antimicrobials. Salmonella was detected in 35.3% of poultry meat, 30.3% of cheese, 21.8% of vegetable, 17.3% of pork, and 15.1% of beef samples, but no Salmonella was detected in fish samples. Significantly higher counts were obtained in chicken meat (P = 0.0001), pork (P = 0.0116), cheese (P = 0.0228), and vegetables (P = 0.0072) obtained from retail stores compared with those samples obtained from supermarkets. Salmonella isolates had high levels of resistance to ampicillin (66.7% of isolates), tetracycline (61.3%), and chloramphenicol (64.5%) and low levels of resistance to cefotaxime (0%), gentamicin (3.2%), and kanamycin (4.3%). Higher levels of quinolone resistance were found in isolates from poultry meat and vegetables compared with that in other foods tested. High levels of multiresistant strains were found in all foods tested except fish, ranging from 100% of pork samples to 47.1% of vegetable samples. The present study revealed that Salmonella prevalence was higher in foods from retail stores than in foods from supermarkets. Resistance rates observed for Salmonella were largely comparable to those reported in other countries for most antimicrobials, although resistance to chloramphenicol tended to be higher.

BACKGROUND To compare the outcomes, as well as the short and long term complications, of percutaneous dilational tracheostomy (PDT) and surgical tracheostomy (ST) at the bedside. METHODS From 2003 to 2005, 367 consecutive patients underwent percutaneous tracheostomy in two general ICUs of a community hospital. Short and long term complications, procedural time, duration on mechanical ventilation, length of stay in the ICU and in the hospital, and mortality rates were compared to a historical cohort of 161 patients treated with surgical tracheostomy. Both groups were comparable in demographic characteristics and severity scores. RESULTS As a whole, 528 mechanically ventilated patients underwent tracheostomy at the bedside. 161 patients received ST and 367 PDT by the single dilator technique. Only minor complications were observed in both groups of patients. PDT was performed more rapidly than ST (5.4+/-5.2 vs 19+/-10 min). STs were performed significantly later than PDT (12.4+/-6 days vs 8.7+/-5.8 days, P<0.05). The overall ICU stay and mean duration of mechanical ventilation were lower in the PDT than in the ST group (18.4+/-13.9 vs 23.3+/-15.8 days, P< 0.05 and 14.2+/-8.1 vs 20.1+/-10.4, P<0.05, respectively). There were no statistically significance differences in ICU and hospital outcome between the two techniques. CONCLUSION Compared with ST, the main advantage of PDT is that it is more rapid and allows the tracheostomy to be performed earlier in the course of ventilatory failure. Early tracheostomy is associated with a shorter duration of mechanical ventilation and a reduced ICU length of stay.

Abstract
BACKGROUND The factors relevant to the prognosis of childhood asthma differ from one population to another. OBJECTIVES To characterize the course of childhood asthma in the catchment area of our hospital, and to identify prognostic factors for this population. METHODS All children given a diagnosis of asthma in the paediatric pulmonology service of a tertiary hospital were followed up for 5 years. RESULTS Satisfactory control of asthma was achieved in 69 % of cases. The factors identified as associated with poor control were allergy to cats and pollen, a large number of crises in the year prior to diagnosis, and younger age at onset. CONCLUSIONS In our region, childhood asthma has a relatively favourable prognosis. The subsequent course of the disease appears to be determined in childhood. The persistence of symptoms appears to depend to a significant extent on the degree of atopy.

Abstract
A study of 100 MZ (55 female and 45 male) and 97 DZ (50 male and 47 female) same-sexed twin pairs was carried out to analyse the genetic component of the variance of the a-b, b-c and c-d interdigital ridge counts by means of the Christian method. Especially for the a-b interdigital ridge count, we found it important to analyse both sexes separately. Our results suggest that the a-b count in males seems to be more influenced by environmental factors than the other counts. For females, the three interdigital counts seem to have a strong genetic component influencing their phenotypic expression. Factor analysis with VARIMAX rotation showed each interdigital ridge count to be genetically independent.
