Background: The novel coronavirus disease 2019 (COVID-19) is an infectious disease that presents an urgent challenge to global health and economy.

Objectives: To assess the effects of population median age and mean ambient temperature on the COVID-19 global pandemic burden.

Methods: We used databases from open access public domains to record population median age, mean ambient temperature, and the numbers of COVID-19 cases and deaths on days 14 and 28 from the pandemic outbreak for each country in the world. We then calculated the correlation between these parameters.

Results: The analysis included 202 countries. A univariate analysis showed that population median age significantly correlated with the cumulative number of cases and deaths, while mean ambient temperature showed a significant inverse correlation with the cumulative number of deaths on days 14 and 28 from the epidemic outbreak. After a multivariate logistic regression analysis only population median age retained its statistically significant correlation.

Conclusions: Country population median age significantly correlated with COVID-19 pandemic burden while mean ambient temperature shows a significant inverse correlation only in univariate analysis. Countries with older populations encountered a heavier burden from the COVID-19 pandemic. This information may be valuable for health systems in planning strategies for combating this global health hazard.

Background: With diagnostic imaging, such as a duplex of the carotid arteries, finding of stenosis and atherosclerotic plaque and consequent end arterectomy may be important for decreasing the danger of developing cerebrovascular accident after transient ischemic attack (TIA).

Objectives: To measure performance rates of duplex of carotid arteries within 72 hours of TIA diagnosis.

Methods: The denominator included all patients who were admitted to emergency departments because of TIA, and the numerator included those who underwent duplex within 72 hours of admission. Inclusion criteria included all patients older than 18 years who were admitted because of TIA according to the ICD9 codes.

Results: Measuring this indicator started in 2015 with 5504 patients and a 58% success rate. The figures for the years 2016, 2017, and 2018 were 5309, 5447, and 5278 patients with success rates of 73%, 79%, and 83%, respectively. Six of 26 hospitals (23.0%) reached the target of 80% in 2018. From 2015 to 2018 a total of 21,538 patients were admitted to emergency departments in Israel and diagnosed with TIA. Of these, 15,722 (72.9%) underwent duplex within 72 hours. The mortality rate within 30 days from diagnosis was 0.81% in patients who performed duplex within 72 hours of diagnosis and 2.37% in patients who did not, odds ratio 2.676, 95% confidence interval 2.051–3.492, P < 0.0001. These results indicate a statistically significant decrease of 65.82%.

Conclusions: A significant decrease in mortality was noted in patients with a new diagnosis of TIA who underwent duplex within 72 hours of diagnosis

Background: The coronavirus disease-2019 (COVID-19) outbreak had an effect on healthcare.

Objectives: To evaluate the presentation and management of patients with acute appendicitis.

Methods: A retrospective study was conducted of all patients presenting with acute appendicitis to the emergency department of a large tertiary center during March and April 2020. Clinical features, diagnostic workup, and management were compared.

Results: Seventy-four patients presented with acute appendicitis during the pandemic compared to 60 patients during the same time the year before. There were no significant differences in patient demographics: age (P = 0.65), gender (P = 0.73), smoking status (P = 0.48). During COVID-19 patients were more likely to complain of right lower quadrant pain (100% vs. 78.3%, P < 0.01). Rates of surgical treatment was similar (83.8% vs. 81.7%, P = 1); mean operative time was longer during COVID-19 (63 ± 23 vs. 52 ± 26 minutes, P = 0.03). There were no significant differences in intra-operative findings including the presence of appendiceal perforation (16.3% vs. 14.5%, P = 0.8), abscess (6.1% vs. 9.7%, P = 0.73), or involvement of cecum or terminal ileum (14.28% vs. 19.63%, P = 1). Postoperative treatment with antibiotics was more prevalent during COVID-19 (37.1% vs. 18%, P = 0.04). Length of stay (1.82 ± 2.04 vs. 2.74 ± 4.68, P = 0.2) and readmission rates (6% vs. 11.3%, P =0.51) were similar.

Conclusion: The COVID-19 pandemic did not significantly affect the presentation, clinical course, management, and outcomes of patients presenting with acute appendicitis.

This focus article is a theoretical reflection on the ethics of allocating respirators to patients in circumstances of shortage, especially during the coronavirus disease-2019 (COVID-19) outbreak in Israel. In this article, respirators are placeholders for similar life-saving modalities in short supply, such as extracorporeal membrane oxygenation machines and intensive care unit beds.

In the article, I propose a system of triage for circumstances of scarcity of respirators. The system separates the hopeless from the curable, granting every treatable person a real chance of cure. The scarcity situation eliminates excesses of medicine, and then allocates respirators by a single scale, combining an evidence-based scoring system with risk-proportionate lottery.

The triage proposed embodies continuity and consistency with the healthcare practices in ordinary times. Yet, I suggest two regulatory modifications: one in relation to expediting review of novel and makeshift solutions and the second in relation to mandatory retrospective research on all relevant medical data and standard (as opposed to experimental) interventions that are influenced by the triage

Background: Superficial temporal artery-middle cerebral artery microvascular bypass (STA-MCA MVB) is an important strategy for the management of selected patients.

Objective: To present our 19-year experience with STA-MCA MVB.

Methods: Data for consecutive patients who underwent STA-MCA MVB from 2000–2019 due to moyamoya/moyamoya-like disease, complex intracranial aneurysms, or intractable brain ischemia due to internal carotid artery or MCA occlusive disease with repeated ischemic events were retrospectively analyzed under a waiver of informed consent. Key surgical steps and the important role of neuroendovascular interventions are presented. Surgical results and late outcomes were analyzed.

Results: The study included 32 patients (17 women [53%], 15 men [47%]), mean age 42.94 years (range 16–66). The patients underwent 37 STA-MCA MVB procedures during the study period: 22 with moyamoya/moyamoya-like disease (69%) underwent 27 surgeries (five bilateral); 7 patients with complex aneurysms (22%) and 3 patients with vascular occlusive disease (9%) underwent unilateral bypass. Five of seven aneurysms were treated with coiling or flow-diverter stent implant prior to bypass surgery; two were clipped during the bypass procedure. There were no surgical complications, no perioperative mortality, and no death from complications related to neurovascular disease at late follow-up. Transient neurological deficits following 7/37 surgeries (19%) resolved with no permanent neurologic sequelae. Transient ischemic attacks occurred only in the immediate postoperative period in four patients (11%).

Conclusions: In specific cases, STA-MCA MVB is a feasible and clinically effective procedure. It is important to preserve this technique in the surgical armamentarium

Background: Pneumocystis jirovecii pneumonia (PJP) is an opportunistic infection in immunocompromised patients. Clusters of PJP, especially among organ transplant recipients in clinic settings were described. Data regarding nosocomial PJP infection among inpatients are limited.

Objectives: To assess the magnitude and characteristics of inpatient healthcare-associated PJP infection (HCA-PJP) in HIV-negative patients.

Methods: A retrospective chart review of hospitalized PJP patients was performed to identify HCA-PJP. The study was performed at six medical centers in Israel from 2006 to 2016. HCA-PJP was defined as cases of hospital-onset or those with documented contact with a PJP patient. We reviewed and cross-matched temporal and spatial co-locations of patients. Clinical laboratory characteristics and outcomes were compared.

Results: Seventy-six cases of PJP were identified. Median age was 63.7 years; 64% men; 44% hematological malignancies; 18% inflammatory diseases; and 61% steroid usage. Thirty-two patients (42%) were defined as HCA-PJP: 18/32 (23.6%) were hospitalized at onset and 14/32 (18.4%) had a previous encounter with a PJP patient. Time from onset of symptoms to diagnosis was shorter in HCA-PJP vs. community-PJP (3.25 vs. 11.23 days, P = 0.009). In multivariate analysis, dyspnea at presentation (odds ratio [OR] 16.79, 95% confidence interval [95%CI] 1.78–157.95) and a tendency toward higher rate of ventilator support (72% vs. 52%, P = 0.07, OR 5.18, 95%CI 0.7–30.3) were independently associated with HCA-PJP, implying abrupt disease progression in HCA-PJP.

Conclusion: HCA-PJP was common. A high level of suspicion for PJP among selected patients with nosocomial respiratory infection is warranted. Isolation of PJP patients should be considered

Background: The incidence of congenital cytomegalovirus (CMV) infection in Israel is 0.7%. Only 10–15% are symptomatic. Valganciclovir has been shown to improve hearing and neurodevelopmental outcomes in neonates with symptomatic congenital CMV infection. Targeted examination of infants who fail routine neonatal hearing screening or have clinical or laboratory findings suggestive of symptomatic congenital CMV infection may be a cost-effective approach.

Objectives: To assess the possibility of targeted examination for the detection of newborns with symptomatic congenital CMV infection.

Methods: A prospective observational study was conducted in 2014–2015 at two medical centers in northern Israel. Included were all newborns who were tested in the first 3 days of life by polymerase chain reaction (PCR) for urine CMV DNA (n=692), either for failure the hearing screening (n=539, 78%), clinical or laboratory findings suggestive of symptomatic congenital CMV infection, or primary CMV infection during pregnancy (n=153, 22%).

Results: During the study period 15,433 newborns were born. The predicted rate of infection was 10–15% (symptomatic) of 0.7% of newborns, namely 0.07–0.105% or 10–15 infants. In fact, 15 infants (0.11%, 95% confidence interval 0.066–0.175) were diagnosed with symptomatic congenital CMV infection, 2/539 (0.37%) in the failed hearing group and 13/153 (8%) in the clinical/laboratory findings group. The incidence of symptomatic congenital CMV infection was within the predicted range.

Conclusions: Targeted examination of only 4.5% (n=692) of newborns detected the predicted number of infants with symptomatic congenital CMV infection in whom valganciclovir therapy is recommended

This year Ramadan occurs during the global coronavirus disease-2019 (COVID-19) pandemic. Data has shown that patients with type 2 diabetes mellitus (T2DM) are prone to severe disease with COVID-19 and with increased mortality. Acute complications such as dehydration, starvation ketosis, ketoacidosis, and the increased risk of coagulopathy and thrombosis should be considered particularly during this pandemic period. Fasting during Ramadan this year and the COVID-19 pandemic is more challenging, not only for patients with T2DM but also for healthcare providers. We present healthcare providers with important aspects to consider during the COVID-19 pandemic for patients with T2DM who intend to fast during Ramadan and other fasting days
