RESUMO

In five experiments (N = 1,490), participants were asked to imagine themselves as programmers of self-driving cars who had to decide how to program the car to respond in a potential accident: spare the driver or spare pedestrians. Alternatively, participants imagined that they were a mayor grappling with difficult moral dilemmas concerning COVID-19. Either they, themselves, had to decide how to program the car or which COVID-19 policy to implement (high-agency condition) or they were told by their superior how to act (low-agency condition). After learning that a tragic outcome occurred because of their action, participants reported their felt culpability. Although we expected people to feel less culpable about the outcome if they acted in accordance with their superior's injunction than if they made the decision themselves, participants actually felt more culpable when they followed their superior's order. Some possible reasons for this counterintuitive finding are discussed.

RESUMO

OBJECTIVE: The higher education industry in the United States is large (almost four million employees and 19 million students) with diverse hazards. METHODS: We apply a novel health services research approach to systematically assess a sample of 55 institutional websites. The accessibility, content, and coverage of occupational health/safety program information were systematically coded for several domains (eg, Occupational Safety and Health Administration (OSHA)-related, specific hazards, clinical, person-oriented, COVID-19, and coverage). RESULTS: Information was more available for programs related to OSHA mandates (eg, chemical hygiene) and specific hazards than for person-oriented programs (eg, counseling). Larger institutions provide better information and more comprehensive programs than smaller institutions. CONCLUSIONS: Higher education institutions warrant increasing attention to occupational health and safety, particularly as COVID-19 increased attention to workplace health issues.

RESUMO

In this article, we document the evolution of research trends (concepts, methods, and aims) within the field of consumer behavior, from the time of its early development to the present day, as a multidisciplinary area of research within marketing. We describe current changes in retailing and real-world consumption and offer suggestions on how to use observations of consumption phenomena to generate new and interesting consumer behavior research questions. Consumption continues to change with technological advancements and shifts in consumers' values and goals. We cannot know the exact shape of things to come, but we polled a sample of leading scholars and summarize their predictions on where the field may be headed in the next twenty years.

RESUMO

OBJECTIVES: HIV elite controllers (ECs) are a unique subgroup of HIV-positive patients who are long-term virologically suppressed in the absence of antiretroviral treatment (ART). The prevalence of this subgroup is estimated to be < 1%. Various cohorts of ECs have been described in developed countries, most of which have been demographically heterogeneous. The aim of this study was to identify ECs in two large African cohorts and to estimate their prevalence in a relatively genetically homogenous population. METHODS: We screened two cohorts of HIV-positive Ethiopian patients. The first cohort resided in Mekelle, Ethiopia. The second was comprised of HIV-positive Ethiopian immigrants in Israel. In the Mekelle cohort, ART-naïve subjects with stable CD4 counts were prospectively screened using two measurements of viral load 6 months apart. Subjects were defined as ECs when both measurements were undetectable. In the Israeli cohort, subjects with consistently undetectable viral loads (mean of 17 viral load measurements/patient) and stable CD4 count > 500 cells/µL were defined as ECs. RESULTS: In the Mekelle cohort, 16 of 9515 patients (0.16%) fitted the definition of EC, whereas seven of 1160 (0.6%) in the Israeli cohort were identified as ECs (P = 0.011). CONCLUSIONS: This is the first large-scale screening for HIV-positive ECs to be performed in entirely African cohorts. The overall prevalence of ECs is within the range of that previously described in developing countries. The significant difference in prevalence between the two cohorts of similar genetic background is probably a consequence of selection bias but warrants further investigation into possible environmental factors which may underlie the EC state.

RESUMO

PURPOSE: Gun access and bullying are risk factors for sustaining or perpetrating violence among adolescents. Our knowledge of gun access among bullied students is limited. METHODS: We used data on students, aged 12-18 years, from the 2011 and 2013 School Crime Supplement to the National Crime Victimization Survey to assess the association between self-reported bullying victimization (traditional and cyber) and access to a loaded gun without adult permission. Prevalence ratios (PRs) and confidence intervals (CIs) were obtained from multivariable Poisson regression using the Taylor series after controlling for student age, sex, family income, public/private school, and race. RESULTS: Of 10,704 participants, 4.2% (95% CI: 3.8%-4.6%) reported gun access. Compared with nonbullied students, those who reported traditional bullying (PR = 2.2; 95% CI: 1.7-2.4), cyberbullying (PR = 2.8; 95% CI: 1.6-4.9), and both (PR = 5.9; 95% CI: 4.6-7.7) were more likely to also report gun access. CONCLUSIONS: Adolescents who experience bullying, particularly those who report both traditional bullying and cyberbullying, are more likely to report access to a loaded gun without adult permission. These findings highlight the importance of developing interventions focused on these modifiable risk factors for preventing self-directed or interpersonal violence among youth.

RESUMO

The objective of the study was to investigate the HIV-mother-to-child transmission (MTCT) rate in Israel. This was a retrospective study of HIV-infected pregnant women, mainly immigrants from Ethiopia, in six Israeli AIDS centres, in 2000-2005. Medical records of mothers and newborns were evaluated for HIV status, treatment and MTCT rates. Three hundred pregnancies of 241 HIV-infected women, resulting in 304 live births, were studied. In 86/241(36%) women, HIV diagnosis was made during the current pregnancy or shortly after labour. Thirty others were diagnosed during previous pregnancies. Highly active antiretroviral therapy (HAART) was prescribed in 76% of pregnancies. The mean viral load before labour was 23,000 +/- 100,000 copies/mL with a mean CD4 of 406 +/- 223 (range 4-1277) cells/mm(3). Caesarian sections were preformed in 175/300 pregnancies (103/175 with viral load <1000 copies/mL). During labour, azidothymidine (AZT) was given to 80% and nevirapine to 8% of the women. Eighty-eight percent of the neonates received AZT for six weeks. The overall HIV-MTCT rate was 3.6%. MTCT correlated significantly with delayed HIV diagnosis, low CD4, lack of HAART during pregnancy and lack of perinatal treatment. HIV treatment of mothers and their newborns throughout pregnancy, labour and perinatal period are crucial for effective prevention of MTCT, emphasizing the need for early HIV screening, diagnosis and treatment.

RESUMO

BACKGROUND: In Israel, <0.06% of the general population is infected with human immunodeficiency virus (HIV), with a much higher prevalence among specific groups. These groups are distinguished demographically by risk behavior category and by virus subtype. We investigated transmission of drug resistance within groups to assess the impact of these factors. METHODS: Plasma samples from >15% of all patients with new diagnoses of HIV infection were randomly collected between June 1999 and June 2003. Sequences from 176 drug-naive patients included 20 of subtype A, 20 of subtype AE, 2 of subtype AC, 29 of subtype B, 100 of subtype C, and 5 of subtype F. RESULTS: Major drug resistance mutations (protease: L90M; reverse transcriptase: M41L, K103N, V106M, M184V, Y181S, G190A, L210W, T215Y/F, and K219R) were detected in 1 subject with A subtype, 3 with subtype B, and 9 with subtype C. In addition, 1 subject with A subtypes, 2 with subtype B, and 10 with subtype C had secondary mutations (protease: M46I; reverse transcriptase: A98G, K101Q, and V108I). Only 1 patient had mutations associated with >1 class of drugs. Among subjects who contracted HIV infection in Israel, 16 of 56 (1 of 7 with subtypes A or AE, 4 of 17 with subtype B, and 11 of 32 with subtype C; P=.7-1.0) carried resistant virus--a significantly higher proportion (P<.001) than in subjects infected in other countries (10 of 120 infected). CONCLUSIONS: Drug-resistant virus was detected in 14.8% of patients with new diagnoses of HIV infection but in 28.6% of patients known to have been infected in Israel. The implications include a need for pretreatment resistance testing and for better programs aimed at prevention of transmission, directed particularly at patients. We did not find significant differences in transmission of resistant virus between those infected with subtypes B and C, despite the different demographic background. A conclusive analysis and interpretation should await a more extensive study.

RESUMO

OBJECTIVE: To determine risk factors associated with the failure of syndromic management of sexually transmitted diseases (STDs) among women seeking treatment in primary healthcare centre in Addis Ababa, Ethiopia. METHODS: Women with symptomatic STDs seeking care in a health centre were prospectively enrolled. A total of 259 women were interviewed and underwent clinical examination; 106 were enrolled and received syndromic STD treatment and 91% returned for follow up. Logistic regression analysis was used to identify risk factors associated with treatment failure. RESULTS: Of the 106 women enrolled and presenting with symptomatic STDs 67% were HIV seropositive. Syndromic STD treatment did not result in clinical improvement in 30% of the women. Having genital ulcer disease, genital ulcer disease with genital discharge, genital warts, bacterial vaginosis and plasma HIV-1 load >10,000 copies RNA/ml or being HIV seropositive were all significantly associated with treatment failure. In multivariate analysis, however, only genital ulcer disease was significantly associated with treatment failure. CONCLUSION: In our setting, the association between HIV and genital ulcer disease caused by herpes may, therefore, be the reason for the failure of treatment.

RESUMO

OBJECTIVE: To compare drug-resistant variants from untreated (naive) and treated patients infected with clade B or C virus. METHODS: Consecutive samples (165) from patients throughout Israel were analyzed. All those in the treated group were failing highly active antiretroviral therapy. RESULTS: There were 87 clade B (14 naive) and 78 clade C (20 naive) [corrected] with significant differences in the prevalence of known drug-resistance mutations between the clades: in naive patients in the protease region M36I 7% and 95% (P < 0.0001), K20R 0% and 27% (P = 0.063), A71V 18% and 0% (P = 0.063), M46I 0% and 13%, and V77I 18% and 0% (P = 0.063), respectively, and in the reverse transcriptase region A98G/S 0% and 20% (P = 0.12), respectively. Most clade C viruses also showed significant differences from clade B consensus sequence at additional protease sites: R41K 100%, H69K/Q 85%, L89M 95% and I93L 80% (P < 0.0001). There were also significant differences (P < 0.03 to < 0.0001) in treated patients in clades B and C: in the protease region L10I 40% and 12%, M36I 26% and 95%, L63P 67% and 40%, A71I 38% and 7%, G73I and V77I 18% and 0%, I84V 16% and 3%, and L90M 40% and 12%, respectively; in the reverse transcriptase M41L 41% and 17%, D67N 41% and12%, K70R 30% and 7%, T215Y 48% and 29%, K219Q 21% and 7%, and A98G/S 3% and 24%, respectively. CONCLUSION: Significantly differences between clade B and C viruses may be associated with development of differing resistance patterns during therapy and may affect drug utility in patients infected with clade C.

RESUMO

Recent studies have shown higher frequencies of the CCR5-delta 32 allele and the CCR5-delta 32/delta 32 genotype, which confers protection against HIV infection, in northern Europe as compared to Mediterranean countries. Here, we analyse the prevalence of CCR5-delta 32 in 922 HIV seronegative blood donors in Israel to verify its frequency in Jews of Ashkenazi and Sephardi origin. A significant difference (P < 0.001) was found between the CCR5-delta 32 allele frequency in Ashkenazi (13.8%) vs (4.9%) Jews. In contrast, no significant difference was observed in the frequency of the CCR2-641 mutation between Ashkenazi (9.2%) and Sephardi (13.4%) Jews. Using the Island model we calculate that a minimal genetic migration rate of 3% per generation would have been necessary if the higher CCR5-delta 32 prevalence in Ashkenazi is to be fully explained by mixing with the indigenous north-European populations. This putative migration rate is 20-fold higher than that currently estimated from other genes, and would correspond to a non-realistic minimal current admixture of 80%. Thus, our results suggest that a positive selection process for CCR5-delta 32 should have occurred in northern Europe at most a 1000 years ago, after the Ashkenazi Jews separated from their Sephardi kin and moved to north Europe.

RESUMO

A high prevalence of human T-lymphotropic virus type I (HTLV-I) infection among Israeli Jews was previously reported. In the present study, screening for HTLV-I of Israeli Jews was expanded to 10 ethnic groups. HTLV-I antibodies were tested by the particle agglutination assay, ELISA, and by Western blot as a confirmatory method. The HTLV-I proviral genome was tested by nested PCR with tax primers (SK43/SK44 and Tr101/Tr102). The PCR tests were carried out in all seropositive subjects and the seronegative family members of the seropositives subjects in the Iranian population. Sixty-eight of the 1,679 subjects (4.1%) were found to be seropositive. The Jews originating from Mashhad had the highest infection rate of 60/306 (20%). Of the 479 Iranian non-Mashhadi Jews, 6 (1.3%) were seropositive. Of the 894 non-Iranian Israelis, only 2 (0.2%) were seropositive. HTLV-I proviral DNA was found in the peripheral blood lymphocytes of 66 out of 68 seropositive subjects and 6 out of 75 seronegative subjects. Sixty out of 123 (49%) Mashhadi Jews and 8 out of 14 (57%) non-Mashhadi Iranian Jews were PCR-positive. Three out of three seropositive non-Iranian Israelis were PCR positive. One non-Iranian Israeli (who originated from Ukraine) without family connections to the Iranian Jews was also PCR-positive. One hundred eighteen saliva samples (84 from subjects of Mashhadi origin, 31 from Iranian origin, and 4 of other origins) were also screened. Antibodies for HTLV-I were found in 23 out of 46 saliva samples from the individuals with particle agglutination (PA) and/or PCR-positive findings in blood. Twenty out of 23 PA-positive saliva samples also contained the proviral DNA. It is concluded that HTLV-I infection in Israel is mainly limited to Jews originating from Iran (most of them from Mashhad) and their family members.

RESUMO

OBJECTIVE: To study the diagnostic process, clinical course, and outcome of Rwandan refugees with meningococcal meningitis, treated in an Israeli field hospital in Goma, Zaire, in the summer of 1994. METHODS: Patient hospital charts and laboratory records were reviewed with critical evaluation of clinical presentation and diagnostic tests. Patients were treated as part of a disaster relief effort in a refugee camp experiencing several coexisting lethal epidemics. RESULTS: A total of 65 patients were identified as having group A meningococcal meningitis. Latex agglutination test for Neisseria meningitidis soluble antigen in the cerebrospinal fluid was found to be a superior diagnostic tool, as compared to Gram stain, and at least as effective as culture. The mortality rate was 14%; mortality was markedly affected by co-morbidity (e.g., dysentery, pneumonia, and malnutrition). CONCLUSIONS: The outcome of patients with meningococcal meningitis, treated in referral centers within a disaster area may be favorable, despite overwhelming coexisting epidemics, and may be comparable to that achieved in advanced medical facilities. Encephalopathy may be a diagnostic pitfall in the perspective of coexisting epidemics, requiring a high index of suspicion and routine lumbar puncture. The latex agglutination test is highly useful in achieving prompt diagnosis of meningococcal meningitis, in particular when sample handling for culture and microscopy is suboptimal.

RESUMO

UNLABELLED: The aim of the study was to compare HIV-related knowledge, beliefs in self-control and sexual behavior of non-drug using and drug using heterosexual men. All individuals attending an HIV testing site during a two-month period were asked to complete a questionnaire anonymously. Data for 49 drug users (DU), most of them non-injectors, were compared to that of 94 non-drug using (non-DU) men with similar education levels (high school or less). Sexual behavior items refer to previous six months. FINDINGS: HIV-related knowledge was reported correctly by the majority of men in both groups, but the DU showed significantly more misconceptions (p < 0.01). Consistent but statistically insignificant lower levels of self-control were reported by the DU. Type of sexual relations and the number of regular sexual partners were not different between the groups: 55% of the DU and 67% of the non-DU were not monogamous. DU had either none or many casual partners (three or more), significantly different from the non-DU. The proportion of DU who never used condoms (65%) was higher as compared to non-DU men (43%, p < 0.05). However, when controlling for type of partnership, this difference was sustained only among monogamous men (82% of DU vs. 42% of non-DU never used condoms, p < 0.05). Condom use was significantly associated with age, HIV knowledge and sexual partnership in the DU. The greater deficiencies in HIV-related knowledge, and the prevalence of risk behaviors among DU require intensive individual and group counselling, specifically adapted for the needs and the culture of drug users in Israel and incorporated with social-influence-orientated change processes.

RESUMO

OBJECTIVES: To examine gender differences in HIV-related knowledge, perceived vulnerability, beliefs in self-control, type of sexual partnership, and their associations with nonuse of condoms. METHODS: Heterosexual men and women who voluntarily attended an HIV testing clinic in Israel were asked to complete a self-report questionnaire. Scales of HIV knowledge and control and a single item for vulnerability were used. Type of sexual relationship (monogamous vs. nonmonogramous) and condom use in vaginal sex (never vs. ever) referred to the previous 6 months. Response rate was 84%; 154 men and 109 women participated. RESULTS: Beliefs in self-control did not form a reliable scale and single items were used. No statistically significant gender differences were found in knowledge, vulnerability, or beliefs in self-control. Levels of correct HIV-related knowledge were high, but so were some misconceptions. The vast majority (87%) perceived themselves as vulnerable to HIV infection. The beliefs in self-control were moderate in some items, and low in others. In logistic regression models, different factors were significantly associated with nonuse of condoms in the two genders: the belief that their lifestyle protected them against HIV infection (OR = 2.72, CI = 1.06-7.03) among men, and being monogamous (OR = 3.72, CI = 1.28-10.8) among women. CONCLUSION: Heterosexual men and women attending an HIV testing clinic need counseling to further lower misconceptions about HIV transmission and additional gender-specific counseling to address HIV-related beliefs.


PIP: This study examined the gender differences in HIV-related knowledge, perceived vulnerability, beliefs about self-control, type of sexual partnership, and their association with nonuse of condoms. A total of 263 heterosexual persons (154 men and 109 women) were asked to complete a self-report questionnaire. Scales of HIV knowledge and control and a single item for vulnerability were used. Type of sexual relationship (monogamous vs. nonmonogamous) and condom use in vaginal sex (never vs. ever) referred to the previous 6 months. Results of this study indicated that there were no major gender differences in HIV-related knowledge, perceived vulnerability, and beliefs. Knowledge was not associated with the non-use of condoms, but other significant associations with non-use of condoms varied by gender: type of partnership (being monogamous) among women and the belief that their lifestyle precludes HIV infection among men. The young and educated adults in the study had accurate knowledge of the recognized modes of HIV transmission, but they still carried considerable levels of misconceptions about HIV transmission. In conclusion, heterosexual men and women attending an HIV testing clinic need counseling to further lower misconceptions about HIV transmission and additional gender-specific counseling to address HIV-related beliefs.

RESUMO

The aim of this study was to identify the HIV types and subtypes prevalent in Israel among different populations in terms of risk or geographic origin of the HIV infection. A total of 149 blood samples were collected from HIV-positive persons from different risk groups for HIV infection who were living in Israel. HIV subtyping was performed by a V3-based peptide enzyme immunoassay, supplemented by direct sequencing of polymerase chain reaction products from the V3 region. Multiple HIV-1 subtypes were shown to circulate in Israel; whereas most of the infections among Israelis and Palestinians were of subtype B, infections among the large Ethiopian population in Israel were caused by HIV-1 subtype C. Occasionally, we found HIV-1 subtypes A and D and a putative B/C recombinant. No HIV-2 infection was identified. Sequence comparisons and phylogenetic tree analyses point at multiple introductions of HIV into the country. The presence of mainly two different HIV-1 subtypes, B and C, in two separated populations in Israel may result in two distinct epidemiologic patterns among HIV-infected individuals in Israel. Subtype C infection among the Ethiopians in Israel opens new research avenues toward better understanding the natural history of infection with HIV-1 subtype C in Ethiopians living in a Western society compared with those living in Ethiopia.

RESUMO

We describe the clinical course and outcome of Rwandan refugees with cholera-like illness (n = 567) and clinical dysentery (n = 1,062) treated at the Israeli Army field hospital in the disaster region of Goma, Zaire, during the summer of 1994. Vigorous fluid administration was the primary therapy, complemented with antibiotics for patients with presumed Shigella infection. Recovery rates were 94% and 96% for patients with cholera and dysentery, respectively. Mortality was substantially affected by comorbid conditions such as pneumonia and meningitis, which occurred in one-quarter of these patients. Infective, metabolic, and surgical complications (including three cases of intussusception) may have contributed to the deaths. The outcome of patients during diarrheal epidemics of cholera or bacillary dysentery may be favorable, even in disaster settings, if patients are evacuated promptly to medical facilities and appropriate therapy is instituted. We close with general observations on procedures to be followed in future epidemics of diarrheal diseases.

RESUMO

During the decade 1985-94, 158 individuals (124 males, 34 females) with HIV/AIDS were seen at the AIDS clinic of Hadassah University Hospital. They comprised 10% of the total reported number of HIV-infected Israelis and included 6% of all reported HIV-infected Ethiopians and all HIV-infected West Bank Palestinians. Most individuals (82%) were self-referred; 12% were detected through the local HIV screening clinic. Risk groups for AIDS were homo/bisexuality (39%), heterosexual relations (30%), intravenous drug abuse (15%), contaminated blood transfusions (9%), born to HIV+ mothers (1%), and hemophilia (< 1%). In 5% (all males) no risk factor was given. Of the 158 individuals 29 were Ethiopian immigrants, 25 West Bank Palestinians, and the rest were local Israelis and tourists. Of the 34 females seen, 21 acquired HIV heterosexually, 6 were intravenous drug abusers, 5 were recipients of contaminated transfusions, and 2 were infants. An initial clinical presentation with full-blown AIDS was observed in 30% of the individuals. The range of clinical presentations was similar to that seen in western countries, with Pneumocystis carinii pneumonia, cytomegalovirus retinitis, mycobacterial infections and Kaposi's sarcoma seen most frequently. One case of disseminated cutaneous leishmaniasis was observed. The mortality rate during the follow-up was 55%. In 35% of individuals the immediate cause of death was severe bacterial infections. The Palestinian subpopulation presented at an advanced stage of the disease with a high incidence of transfusion recipients, while most HIV-infected Ethiopians presented with asymptomatic disease transmitted heterosexually. HIV/AIDS as seen at Hadassah University Hospital during 1985-94 exhibited the mixed form of Euro-American AIDS with additional facets of recently introduced African infection.
