Background: Previous studies showed that the fourth SARS-CoV-2 vaccine dose has a protective effect against infection, as well as against severe disease and death. This study aimed to examine whether knowledge of a high-level antibody after the third dose may reduce compliance to the fourth booster dose among healthcare workers (HCWs). Methods: We conducted a prospective cohort study among HCWs vaccinated with the first three doses at Rambam Healthcare Campus, a tertiary hospital in northern Israel. Participants underwent a serological test before the fourth booster vaccine was offered to all of them, with results provided to participants. The population was divided into two groups, namely those with antibodies below 955 AU/mL and those with 955 AU/mL and higher, a cutoff found protective in a previous study. Multiple logistic regression was carried out to compare the compliance to the fourth booster between the two groups, adjusted for demographic and clinical variables. Results: After adjusting for the confounding variables, the compliance was higher in those with antibody levels below 955 AU/mL (OR = 1.41, p = 0.05, 95% CI 1.10–1.96). In addition, male sex and age of 60 years and above were also associated with higher vaccination rates (OR = 2.28, p < 0.001, 95% CI 1.64–3.17), (OR = 1.14, p = 0.043, 95% CI 1.06–1.75), respectively. Conclusions: Knowledge of the antibody status may affect compliance with the booster dose. Considering waning immunity over time, reduced compliance may affect the protection of HCWs who declined the fourth dose. [ABSTRACT FROM AUTHOR]

Background Efficient infection control during carbapenem-resistant Enterobacterales outbreaks demands rapid and simple techniques for outbreak investigations. WGS, the current gold standard for outbreak identification, is expensive, time-consuming and requires a high level of expertise. Fourier-transform infrared (FTIR) spectroscopy (IR Biotyper) is a rapid typing method based on infrared radiation applied to samples, which provides a highly specific absorption spectrum. Objectives To investigate an outbreak of OXA-48-producing Escherichia coli in real-time using FTIR and subsequently compare the results with WGS. Methods Twenty-one isolates were collected during a nosocomial outbreak, and identification and antibiotic susceptibilities were confirmed by VITEK®2. FTIR was conducted for all isolates, and nine representative isolates were sequenced. Results FTIR was able to correctly determine the clonal relatedness of the isolates and to identify the outbreak cluster, as confirmed by WGS. By WGS, isolates in the main FTIR cluster belonged to the same MLST type and core-genome MLST type, and they harboured similar plasmids and resistance genes, whereas the singletons external to the FTIR cluster had different genetic content. Conclusions FTIR can operate as a rapid, efficient and reliable first-line tool for outbreak investigations during a real-time ongoing E. coli outbreak, which can contribute to limiting the spread of pathogens.

Subjective health (SH) status serves as a measure of health in many studies of health-related issues as it is a good predictor of mortality, morbidity, and use of health services. The measure is used in many population groups. However, the degree to which it measures the same condition in different ethnic groups is not clear. Within Israel's first National Health and Nutrition Survey (MABAT) conducted during 1999-2001, face-to-face interviews were held with 3222 Israeli interviewees, 2379 Jews and 843 Arabs, aged between 25-64 years. Respondents reported their SH, co-morbidity, and other socioeconomic characteristics. Arabs reported higher levels of SH than Jews. In logistic regression analysis, co-morbidity was a much stronger correlate of poorer SH in the Arab than in the Jewish population. The association between socioeconomic variables depended on ethnic group and sex. The findings indicate that SH in Jews and Arabs does not necessarily have the same meaning in relation to objective measures of health, and caution should be exercised in the use of this measure in different population groups with different cultures. Arabs tend to evaluate health better than Jews even though life expectancy is lower and morbidity and mortality are higher in the former population group. Yet diagnosis of a disease increases the frequency of reporting lower SH, more in Arabs than in Jews. Keywords: Subjective health; Self-reported health; Arabs; Jews; Israel; Culture; Measurement

Background: With the availability of coronavirus disease 2019 (COVID-19) vaccine, concerns have been raised regarding pre-vaccination seroprevalence in healthcare workers (HCW). This study examines the seroprevalence of HCW at an Israeli tertiary medical center before first BNT162b2 vaccination. Methods: This was a retrospective observational study. Before vaccination, HCW at our center were offered serological testing. Data on their epidemiological, workplace, and quarantine history were collected. The SARS-CoV-2 IgG assay was performed pre-vaccination. Results: A total of 4,519 (82.5%) of the HCW were tested. Of these, 210 were seropositive; 101 had no known history of COVID-19. Of the 101 asymptomatic HCW, only 3 (3%) had worked at COVID-19 departments, and 70 (69.3%) had not been previously quarantined. Positive serology was similarly distributed across age groups, and about 40% had no children. Nearly half of the HCW tested were administrative and service staff. Overall, seropositive tests were associated with having no children (OR 1.42, 95% CI 1.06–1.89; P=0.0218), history of having been quarantined without proof of disease (OR 6.04, 95% CI 4.55–8.01; P<0.001), and Arab ethnicity (OR 3.36, 95% CI 2.54–4.43; P<0.001). Seropositivity was also more prevalent in members of the administration compared to other sectors, medical and paramedical, who are exposed to patients in their daily work (OR 1.365, 95% CI 1.02–1.82; P=0.04). Conclusions: The low percentage of asymptomatic COVID-19 among our HCW may reflect the high compliance to personal protective equipment use despite treating hundreds of COVID-19 patients. The relatively high number of childless seropositive HCW could reflect misconceptions regarding children as a main source of infection, leading to carelessness regarding the need for appropriate out-of-hospital protection.

Abstract Background Data for predicting which patients with pandemic influenza A (H1N1) infection are likely to run a complicated course are sparse. We retrospectively studied whether the admission serum C-reactive protein (CRP) levels can serve as a predictor of illness severity. Methods Included were all consecutive adult patients who presented to the emergency department (ED) between May-December, 2009 with a flu-like illness, a confirmed diagnosis of pandemic influenza A (H1N1) infection and a serum CRP level measured within 24 hours of presentation. Patients with a proven additional concurrent acute illness (e.g., bacteremia) were excluded. We used the ROC curve analysis, Kaplan-Meier curves and the Cox proportional hazard model to evaluate the predictive ability of CRP as a prognostic factor. Results Seventeen (9%) of the 191 enrolled patients were admitted to the intensive care unit (ICU), of whom eight (4%) required mechanical ventilation and three (2%) died. The median admission serum CRP levels were significantly higher among patients who required subsequent ICU care and mechanical ventilation than among patients who did not (123 mg/L and 112 mg/L vs. 40 mg/L, p < .001 and 43 mg/L, p = .017, respectively). A Cox proportional hazard model identified admission serum CRP levels and auscultatory findings over the lungs as independent prognostic factors for ICU admission. Admission serum CRP levels were the only independent prognostic factor for mechanical ventilation. Thirty days after presenting to the ED, none of the patients with admission serum CRP level p < .001 for ICU and p < .024 for mechanical ventilation). Conclusions In our study group, serum CRP levels obtained in the early ED admission stage from patients presenting with pandemic H1N1 influenza A infection were found to serve as a useful gauge for predicting disease course and assisting in patient management.

Background In Israel, the whole population is covered by comprehensive universal health insurance. Despite that, most of the population purchases supplementary health insurance (SHI). It has been shown that individuals purchase more health insurance and preventive medicine when they are uncertain of their state of health, while a majority may not fully understand basic concepts in their health insurance coverage. The purpose of this study was to examine the role of fear of catastrophic health expenditures and unrealistic expectations in purchasing SHI, which does not cover expenses for life-threatening illnesses. Methods A cross-sectional survey was conducted among random samples of 814 Jews and 800 Arabs in Israel. A structured questionnaire was administered by telephone using random digit dialling. Log-linear regression was used to identify factors associated with reasons for purchasing SHI and expectations from SHI. Results The most common reason for purchasing SHI was fear of catastrophic health-related expenditures (41%). The most important service expected from SHI was 'cancer medications' (mean 4.68 [standard deviation 0.87]). Differences in the reasons for purchasing SHI and in expectations from SHI were found according to population group, age, gender and education. Conclusions Consumers' misconceptions and fear of catastrophic health expenditures are major factors leading to the purchase of SHI, despite universal health coverage. Improved and accessible information should help consumers make informed decisions as to whether or not to purchase SHI. [ABSTRACT FROM AUTHOR]

Background: The infant mortality rate is a health status indicator., Objectives: To analyze the differences in infant mortality rates between Jews and Arabs in Israel between 1975 and 2000., Methods: Data were used from the Central Bureau of Statistics and the Department of Mother, Child and Adolescent Health in the Ministry of Health., Results: The IMR in 2000 was 8.6 per 1,000 live births in the Israeli Arab population as compared to 4.0 in the Jewish population. Between 1970 and 2000 the IMR decreased by 78% among Moslems, 82% among Druze, and 88% among Christians, as compared to 79% in the Jewish population. In 2000, in the Arab population, 40% of all infant deaths were caused by congenital malformations and 29% by prematurity, compared to 23% and 53%, respectively, in the Jewish population. Between 1970 and 2000 the rate of congenital malformations declined in both the Arab and Jewish populations. In the 1970s the rate was 1.4 times higher in the Arab community than in the Jewish community, and in 2000 it was 3.7 times higher., Conclusion: As in the Jewish population, the IMR in the Arab community has decreased over the years, although it is still much higher than that in the Jewish community. Much remains to be done to reduce the incidence of congenital malformations among Arabs, since this is the main cause of the high IMR in this population.
