Background: Channeling medical resources for coronavirus disease-2019 (COVID-19) management can potentially endanger routine healthcare practices. As a preventive measure, a department of obstetrics and gynecology in Israel constructed a separate, designated complex for its COVID-19-exposed patients.

Objectives: To evaluate the effect of the COVID-19 pandemic infection control measures on obstetric care in the obstetrical emergency department and delivery unit.

Methods: The authors collected data retrospectively from February 2020 to March 2020 and compared it to data of a parallel period in 2019.

Results: From 1 February 2020 to 28 March 2020, 3897 women were referred to the emergency department (ED), compared to 4067 the previous year. Mean duration of treatment until decision and referral indications did not differ between 2020 and 2019 (207 vs. 220 minutes, P = 0.26; urgent referrals 58.8% vs. 59.2%, P = 0.83). A per-week comparison showed a significant reduction in ED referrals only in the last week of the period (337 [2020] vs. 515 [2019], P < 0.001). The proportion of women admitted to the delivery unit in active labor was significantly higher in the last three weeks (39.1% vs. 28.2%, P = 0.005). During February and March 2020, 1666 women delivered, compared to 1654 during February and March 2019. The proportion of types and modes of delivery did not differ. In a per-week comparison, the number of deliveries did not differ (mean 208 vs. 206, P = 0.88).

Conclusions: With timely preparation and proper management, negative impact of COVID-19 can be reduced in obstetrical emergency departments.

Background: Social distancing, implemented to decrease the spread of coronavirus disease-2019 (COVID-19), forced major changes in medical practices, including an abrupt transition from face-to-face to remote patient care. Pre-clinical medical studies were concomitantly switched to electronic distance learning.

Objectives: To explore potential implications of COVID-19 on future pre-clinical medical studies.

Methods: We examined responses of pre-clinical medical students to the remote electronic learning in terms of quality of and satisfaction with teaching and technical support, attendance to classes, and the desire to continue electronic learning in the post-epidemic era. A survey of responses from first-year students at the Adelson School of Medicine was conducted. To optimize the reliability of the survey, a single research assistant conducted telephone interviews with each student, using a structured questionnaire concerning aspects of participation and satisfaction with teaching and with technical components of the remote electronic learning.

Results: With 100% response rate, the students reported high satisfaction with the electronic learning regarding its quality, online interactions, instructions given, technical assistance, and availability of recording for future studies. Most of the students (68.6%) noted a preference to continue < 90% of the learning online in the post-outbreak era. A high level of overall satisfaction and a low rate of technical problems during electronic learning were significantly correlated with the desire to continue online learning (P < 0.01).

Conclusions: The high satisfaction and the positive experience with the electronic distance learning imposed by the COVID-19 epidemic implied a successful transition and might induce future changes in pre-clinical medical studies.

Background: Ferritin, the cellular protein storage for iron, has emerged as a key molecule in the immune system, orchestrating the cellular defense against inflammation. At the end of 2019, the novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) rapidly spread throughout China and other countries around the world, resulting in a viral pandemic.

Objectives: To evaluate the correlation between ferritin and disease severity in coronavirus disease-2019 (COVID-19).

Methods: In this cross-sectional study, we obtained clinical and laboratory data regarding 39 hospitalized patients with confirmed COVID-19 from two hospitals in Israel.

Results: A significant increase in ferritin levels was demonstrated in patients with moderate and severe disease, compared to patients with mild disease (P = 0.006 and 0.005, respectively). Severe patients had significantly higher levels of ferritin (2817.6 ng/ml) than non-severe patients (708.6 ng/ml) P = 0.02.

Conclusions: In this preliminary cross-sectional study, elevated ferritin levels were shown to correlate with disease severity in 39 patients from Israel with confirmed COVID-19 infection. Our results further strengthen the hypothesis that severe COVID-19 disease might be due to an underlying dysregulated hyperimmune response. In order to identify these patients early and prioritized resources, we believe that all patients with COVID-19 should be screened for hyperferritinemia.

Background: The 2019 severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic continued into 2020, and the coronavirus disease-2019 (COVID-19) associated death toll increased.

Objectives: To analyze COVID-19 death rates in European countries or regions to determine whether there was a significant association between bacillus Calmette-Guérin (BCG) vaccination policy and lower rates of COVID-19 related deaths.

Methods: Certain Northern European countries or regions had low death rates regardless of BCG policy. The authors assumed the consumption of foods containing salmiak (NH₄Cl) was a common and peculiar cause of the reduced COVID-19 related death rates in these countries, because NH₄Cl is a known lysosomotropic agent, which has been indicated to inhibit or prevent SARS-CoV infection. To check the possible effectiveness of salmiak consumption against COVID-19 related death, the authors used a linear regression model with the death rate as the dependent variable and BCG-policy and salmiak consumption score as independent variables.

Results: Using least squares regression and a robust standard error algorithm, the authors found a significant effect exerted by the independent variables (P < 0.0005 for BCG and P = 0.001 for salmiak). Salmiak score alone was significant (P = 0.016) when using least squares regression with robust error algorithm. 

Conclusions: The results seem to confirm an association between BCG-positive vaccination policy and salmiak consumption, and lower death rates from COVID-19. Implementing BCG vaccination policy and fortification of foods with salmiak (NH₄Cl) may have a significant impact on the control of SARS-CoV epidemic.

In this review we described the values of commonly available HScore laboratory markers in patients with coronavirus-19 (COVID-19)-pneumonia associated cytokine storm syndrome (CPN-CSS) and compared results with those of other forms cytokine storm syndrome (O-CSS) to determine a pattern for CPN-CSS. Twelve CPN-CSS studies and six O-CSS studies were included. CPN-CSS typically obtained a single HScore value (e.g., aspartate transaminase > 30 U/L) while failing all other HScore criteria. A typical pattern for CPN-CSS was revealed when compared to O-CSS: lymphopenia vs. pancytopenia and increased vs. decreased fibrinogen. Findings, other than HScore commonly found in CPN-CSS studies, showed elevated lactate dehydrogenase, D-dimer, and C-reactive protein. Although CPN-CSS studies describe severely ill patients, the HScore markers are typically less toxic that O-CSS

A virally-induced cytokine storm syndrome, associated with a massive and overwhelming systemic inflammation, burdens a subgroup of patients with severe coronavirus disease-2019 (COVID-19), which leads to pulmonary inflammation and extensive lung damage. These severe COVID-19 patients are characterized by high ferritin levels. These findings mirror what was previously reported about the prognostic role of this iron storage protein in other inflammatory diseases included in the hyperferritinemic syndrome. The latter suggests that ferritin could be a further pathogenic mediator in enhancing the inflammatory process, stimulating inflammatory pathways, and thus perpetuating a vicious pathogenic loop. Considering its activity as an immune activator, a therapeutic approach targeting ferritin may be also postulated in these diseases. Considering these observations, high ferritin levels characterize severe COVID-19 and other diseases included in the hyperferritinemic syndrome. Because ferritin could enhance the inflammatory process, it could be tested as a possible new therapeutic target to improve the outcome of these patients.

There is a high prevalence of olfaction changes, especially in the early presentation, in COVID-19 patients. The mechanisms through which the virus leads to anosmia/hyposmia is still not fully understood. However, olfaction changes could be used as an indication for testing or quarantine. Screening for infections and other diseases by recognizing volatile organic compounds (VOCs) has been previously conducted. Hence, if the coronavirus infection also results in VOCs excretion, physicians could “smell” the virus by using electronic noses. We conducted a literature review on olfaction changes and the COVID-19. Our results suggest that these changes could be used an indication for early testing, even as an isolated symptom. We propose that the electronic nose be used as a future screening tool, especially in agglomeration spaces such as airports, for screening for the COVID-19 infection

Background: Emergency department (ED) overcrowding is associated with worse patient outcomes.

Objectives: To determine whether physician assistants (PAs), fairly recently integrated into the Israeli healthcare system, improve patient outcomes and ED timings.

Methods: We compared patients seen by physicians with patients seen by PAs and then by physicians between January and December 2018 using propensity matching. Patients were matched for age, gender, triage level, and decision to hospitalize. Primary endpoints included patient mortality, re-admittance. and leaving on own accord rates. Secondary endpoints were ED timing landmarks.

Results: Patients first seen by PAs were less likely to leave on their own accord (MD1 1.5%, PA 1.0%, P = 0.015), had lower rates of readmission within 48 hours (MD1 2.1%, PA 1.5%, P= 0.028), and were quicker to be seen, to have medications prescribed, and to undergo imaging without differences in timings until decisions were made or total length of stay. Patients seen by a physician with the assistance of a PA were attended to quicker (MD2 47.79 minutes, range 27.70–78.82 vs. MD + PA 30.59 minutes, range 15.77–54.85; P < 0.001) without statistically significant differences in primary outcomes. Mortality rates were similar for all comparisons.

Conclusions: Patients first seen by PAs had lower rates of re-admittance or leaving on their own accord and enjoyed shorter waiting times. Pending proper integration into healthcare teams, PAs can further improve outcomes in EDs and patient satisfaction.

Background: Belimumab was the first biological drug approved for the treatment of systemic lupus erythematosus (SLE) patients. Phase II/III randomized controlled trials and real-life studies identified patients with musculoskeletal involvement as best responders.

Objective: To evaluate the effectiveness of belimumab in SLE-related joint involvement.

Methods: The cohort comprised SLE patients receiving belimumab for musculoskeletal indications. Belimumab was intravenously administrated according to protocols; all the patients were evaluated at baseline (T0) and after 3 (T1), 6 (T2), and 12 (T3) months. We assessed joint activity by disease activity score 28, simple disease activity index (SDAI), clinical disease activity index (CDAI), and swollen tender ratio. Each patient underwent musculoskeletal ultrasound of 34 joints to assess synovial effusion synovial hypertrophy, and power Doppler; by using a semi-quantitative scale (0–3) we obtained the total inflammatory score (0–216).

Results: We evaluated 20 patients (males/females 1/19, median age 45 years [interquartile range (IQR) 12], median disease duration 144 months [IQR 144]). CDAI and SDAI significantly decreased at T1 (P = 0.02 and P = 0.01 respectively) and this improvement was maintained at the following time-points (CDAI: T2 P = 0.008, T3 P = 0.004; SDAI: T2 P = 0.006, T3 P = 0.01). A significant reduction of median ultrasound score was identified at T1 (T0 20.5 [IQR 13.5] vs. T1 7.5 [IQR 4.7], P < 0.001), and maintained at T2 (7.0 [IQR 5], P < 0.0001), and T3 (7.0 [IQR 9.0], P < 0.0001).

Conclusions: Belimumab induces a sustained improvement of ultrasound-detected inflammatory status at the articular level.

Background: While the ratio of male to female births (sex-ratio at birth [SRB]) in humans is remarkably stable on the population level, there are many families with multiple same-sex offspring.

Objectives: To identify a putative sub-population with skewed SRB and explore potential factors affecting the SRB.

Methods: A retrospective cohort study including 66,054 families with up to nine same-sex offspring evaluated between 2003 and 2015 at Hadassah-Hebrew University Medical Center. Outcome measures were observed prevalence and SRB of families with up to nine same-sex offspring in a single family. Analyses included the effect of parity, month and year of delivery, inter-delivery interval, and presence of a sequence of previous same-sex offspring on the SRB.

Results: The study comprised 193,411 live-born babies with SRB of 1.057 in favor of males. The proportion of SRB in families with up to nine same-sex offspring did not differ from the calculated presumed proportion. Furthermore, none of the tested factors (parity, month and year of delivery, inter-delivery interval, and the sequence of previous same-sex offspring) were significantly associated with SRB.

Conclusions: SRB was not associated with any of the tested demographic characteristics. We could not identify a skew in SRB even in families with up to nine consecutive same sex offspring. This finding suggests that in the majority of the population the chance of a male or female fetus in each pregnancy remains similar in every pregnancy, regardless of any of the tested variables.
