Background: In February 2020, the World Health Organisation designated the name COVID-19 for a clinical condition caused by a virus identified as a cause for a cluster of pneumonia cases in Wuhan, China. The virus subsequently spread worldwide, causing havoc to medical systems and paralyzing global economies. The first COVID-19 patient in Israel was diagnosed on 27 February 2020.

Objectives: To present our findings and experiences as the first and largest center for COVID-19 patients in Israel.

Methods: The current analysis included all COVID-19 patients treated in Sheba Medical Center from February 2020 to April 2020. Clinical, laboratory, and epidemiological data gathered during their hospitalization are presented.

Results: Our 162 patient cohort included mostly adult (mean age of 52 ± 20 years) males (65%). Patients classified as severe COVID-19 were significantly older and had higher prevalence of arterial hypertension and diabetes. They also had significantly higher white blood cell counts, absolute neutrophil counts, and lactate dehydrogenase. Low folic acid blood levels were more common amongst severe patients (18.2 vs. 12.9 vs. 9.8, P = 0.014). The rate of immune compromised patients (12%) in our cohort was also higher than in the general population. The rate of deterioration from moderate to severe disease was high: 9% necessitated non-invasive oxygenation and 15% were intubated and mechanically ventilated. The mortality rate was 3.1%.

Conclusions: COVID-19 patients present a challenge for healthcare professionals and the whole medical system. We hope our findings will assist other providers and institutions in their care for these patients.

Background: Guidelines recommend initiation of parenteral biologic or oral target-specific disease-modifying anti-rheumatic drugs (bDMARDs/tsDMARDs) in rheumatoid arthritis (RA) patients who do not adequately respond to conventional DMARDs.

Objectives: To compare the preferred route of administration of bDMARDs or tsDMARDs in RA patients who were previously treated with at least one type.

Methods: A cross-sectional survey was conducted of consecutive RA patients previously prescribed bDMARDs or tsDMARDs. We analyzed the factors associated with patients' preferred route of administration.

Results: The cohort included 95 patients, mostly female (72.6%), seropositive (81.05%), mean age 63.4 ± 11.9 years. The oral route was preferred by 39 patients (41%) and 56 (59%) preferred the parenteral route. Most patients (65.9%) preferred to continue with their current route (P < 0.001). Switching from a current route was less common with patients who were currently using the oral route (13.3% vs. 38.2%, P = 0.04). Many patients (53.8%) who preferred the oral route had never experienced it before, while this was rare (3.6%) regarding the parenteral route (P = 0.0001). Employment status was associated with preference of the subcutaneous route over the intravenous route of bDMARDs (P = 0.01). Of the 21 patients who had previously experienced both parenteral and oral treatment, 16 (76.2%) preferred the oral route.

Conclusions: RA patients preferred to continue treatment with an administration route they have already experienced. However, when choosing an unexperienced route, significantly more patients preferred the oral route. Our results strengthen the understanding of patient preferences, which could improve drug adherence, compliance, and disease outcome.

Background: Heart failure centers with specialized nurse-supervised management programs have been proposed to improve prognosis. The Heart Failure Center in Beit Shemesh, Israel, is located within a large primary care facility. The specialist team supervised the managememt of patients both within the frame of the center and while they were hospitalized.

Objectives: To evaluate the health services utilization by heart failure patients treated at a heart failure center and their clinical outcome.

Methods: In this retrospective study, we compared the clinical outcome of patients treated at a heart failure center to patients who received the standard care in 2013–2014. The clinical outcome included primary care visits, emergency room visits, hospitalizations, and death.

Results: The study comprised 430 heart failure patients; 82 were treated at the heart failure center and 348 under standard care. At baseline, no significant differences were seen in clinical parameters between the groups. Healthcare utilization was higher among the study group. No significant changes in healthcare utilization were found. During follow-up, patients treated in a heart failure center were more likely to get recommended heart failure medications. Mortality was significantly lower in patients treated in the heart failure center compared with those receiving standard care 3.6% vs. 24%, respectively (P = 0.001), hazard ratio 0.19, 95% confidence interval 0.06–0.62, P = 0.005.

Conclusions: Joint management of heart failure by primary clinics and a specialized community heart failure center reduced mortality. There was no decrease in healthcare utilizations among heart failure center patients, despite the reduction in mortality.

Background: Anastomotic leakage (AL) is a major complication following colorectal surgery, with many risk factors established to date. The incidence of AL varies in the medical literature and is dependent on research inclusion criteria and diagnostic criteria.

Objectives: To determine the incidence of and the potential risk factors for AL following colorectal surgery at a single academic medical center.

Methods: We retrospectively reviewed all operative reports of colorectal procedures that included bowel resection and primary bowel anastomosis performed at Sheba Medical Center during 2012. AL was defined according to the 1991 United Kingdom Surgical Infection Study Group criteria. Data were assessed for leak incidence within 30 days. In addition, 17 possible risk factors for leakage were analyzed. A literature review was conducted.

Results: This cohort study comprised 260 patients, and included 261 procedures performed during the study period. The overall leak rate was 8.4%. In a univariate analysis, male sex (odds ratio [OR] 3.37, 95% confidence interval [95%CI] 1.21–9.43), pulmonary disease (OR 3.99, 95%CI 1.49–10.73), current or past smoking (OR 2.93, 95%CI 1.21–7.10), and American Society of Anesthesiologist score ≥ 3 (OR 3.08, 95%CI 1.16–8.13) were associated with an increased risk for anastomotic leakage. In a multivariate analysis, male gender (OR 3.62, 95%CI 1.27–10.33) and pulmonary disease (OR 4.37, 95%CI 1.58–12.10) were associated with a greater risk.

Conclusions: The incidence of AL in the present study is similar to that found in comparable series. Respiratory co-morbidity and male sex were found to be the most significant risk factors.

Background: Multidisciplinary biopsychosocial rehabilitation for patients presenting with rheumatic diseases has been shown to produce better results in a warm climate. Dead Sea Climatotherapy (DSC) has been successfully used for decades to treat many patients with rheumatic diseases.

Objectives: To evaluate the short-term improvement of Norwegian patients who presented with chronic pain following a multidisciplinary biopsychosocial approach to treatment combined with DSC. Both objective and subjective clinical parameters were evaluated.

Methods: This retrospective study included a statistical analysis of 938 patients presenting with rheumatoid arthritis and ankylosing spondylitis (n=105), osteoarthritis (n=342), fibromyalgia (n=374), and other orthopedic conditions (n=117). Clinical assessments were conducted before and after a 3 week treatment program at the Dead Sea.

Results: Six parameters improved significantly in the rheumatoid arthritis and ankylosing spondylitis group as well as in the osteoarthritis group. Five parameters in the fibromyalgia group improved, while two improved in the orthopedic conditions group. Overall, major significant changes occurred in the pain self-assessment, joint motility, and daily activities scores.

Conclusions: A 3-week multidisciplinary biopsychosocial program combined with DSC induced positive changes in the clinical parameters of Norwegian patients presenting with chronic musculoskeletal pain.

Background: A patient`s individual chance of being diagnosed with cardiovascular disease can be determined by risk scores.

Objectives: To determine the risk score profiles of patients presenting with a first acute coronary event according to pre-admission risk factors and to evaluate its association with long-term mortality.

Methods: The research was based on a retrospective study of a cohort from the 2010 and 2013 Acute Coronary Syndrome Israeli Surveys (ACSIS). Inclusion criteria included first event and no history of coronary heart disease or cardiovascular disease risk equivalent. The Framingham Risk Score, the European Systematic COronary Risk Evaluation (SCORE), and the American College of Cardiology/American Heart Association/ (ACC/AHA) risk calculator were computed for each patient. The risk profile of each patients was determined by the three scores. The prognostic value of each score for 5 year survival was evaluated.

Results: The study population comprised 1338 patients enrolled in the prospective ACSIS survey. The ACC/AHA score was the most accurate in identifying patients as high risk based on pre-admission risk factors (73% of the subjects). The Framingham algorithm identified 53%, whereas SCORE recognized only 4%. After multivariate adjustment for clinical factors at presentation, we found that no scores were independently associated with 5 year mortality following the first acute coronary event.

Conclusions: Patients with first acute coronary event had a higher pre-admission risk scores according to the ACC/AHA risk algorithm. No risk scores were independently associated with 5 year survival after an event.

Background: Biological agents for anti-tumor necrosis factor-α therapy have revolutionized treatments for autoimmune diseases; however, approximately 20% of rheumatology and 40% of gastroenterology patients do not respond to the therapy, or they show reduced drug efficacy because of anti-drug antibody (ADA) formation.

Objectives: To evaluate laboratory tools for individual monitoring of infliximab therapy and the relationship between ADA and infliximab serum levels, ADA and clinical response, and ADA and autoantibodies.

Methods: Our study comprised patients treated with infliximab and affected by selected rheumatology and gastroenterology diseases. Sera were analyzed for infliximab, total-anti-drug antibodies (Total-ADA), and free-anti-drug antibodies (Free-ADA) serum levels and for the detection of specific autoantibodies.

Results: We analyzed 73 patients. Total-ADA were detected in 26 rheumatology and 21 gastroenterology patients. Serum infliximab levels were significantly lower in Total-ADA positive patients (P = 0.01 for rheumatology group, P = 0.02 for gastroenterology group). A lack of response was observed in 7 rheumatology and 15 gastroenterology samples. Total-ADA serum levels were statistically significantly higher in patients with treatment failure in both groups (P = 0.01 and P = 0.001, respectively). There was no significant association between the presence of Total-ADA and other autoantibodies. Free-ADA were detected in only 27 rheumatology patients. Results showed a significant correlation with clinical outcome (P = 0.006).

Conclusions: The correlation with clinical response suggests that the presence of ADA could interfere with efficacy of therapy. The tests for monitoring therapy may be an important tool to assist clinicians in early detection and prevention of therapy failure.

Background: Evidence has shown that pregnancy failure (PF) in women with systemic sclerosis (SSc) consists mainly of preterm delivery (PD) and intrauterine growth restriction (IUGR). Thyroid dysfunction (TD) and Hashimoto's thyroiditis (HT) represent a common feature of SSc. Since TD has been associated with PF, its presence in SSc women may potentially affect pregnancy outcome. 

Objectives: To analyze the interplay between TD and PF in a cohort of SSc women. 

Methods: SSc women (n=77) and age-matched controls from the general obstetric population (n=50) were included. Clinical/biochemical/instrumental data exploring TD and the visceral involvement were collected in the context of a clinical practice setting. Pregnancy outcome was assessed by registering the history of primary infertility, recurrent spontaneous abortion, PD (≤ 37 gestational week), IUGR, and intrauterine fetal death. 

Results: A higher prevalence of PD/IUGR was recorded in the SSc cohort than the controls (P = 0.04). SSc women with PF showed a higher prevalence of diffuse SSc than women without PF (P = 0.03). Scl-70 positive SSc women had a higher prevalence of PF than women with anti-centromere positivity (P = 0.01). A higher prevalence of HT was recorded in SSc women with PF than in patients without (P = 0.04). 

Conclusions: Our findings support the evidence that women with SSc can have successful pregnancies despite a higher prevalence of PD/IUGR. Diffuse SSc and Scl-70 positivity may predispose SSc women to PF. Routine thyroid workup may be included in the multi-specialist monitoring of SSc women for the early detection of thyroid dysfunctions.

 

Background: Warm compresses are widely touted as an effective treatment for ocular surface disorders. Black tea compresses are a common household remedy, although there is no evidence in the medical literature proving their effect and their use may lead to harmful side effects. 

Objectives: To describe a case in which the application of black tea to an eye with a corneal epithelial defect led to anterior stromal discoloration; evaluate the prevalence of hot tea compress use; and analyze, in vitro, the discoloring effect of tea compresses on a model of a porcine eye.

Methods: We assessed the prevalence of hot tea compresses in our community and explored the effect of warm tea compresses on the cornea when the corneal epithelium’s integrity is disrupted. An in vitro experiment in which warm compresses were applied to 18 fresh porcine eyes was performed. In half the eyes a corneal epithelial defect was created and in the other half the epithelium was intact. Both groups were divided into subgroups of three eyes each and treated experimentally with warm black tea compresses, pure water, or chamomile tea compresses. We also performed a study in patients with a history of tea compress use. 

Results: Brown discoloration of the anterior stroma appeared only in the porcine corneas that had an epithelial defect and were treated with black tea compresses. No other eyes from any group showed discoloration. Of the patients included in our survey, approximately 50% had applied some sort of tea ingredient as a solid compressor or as the hot liquid.

Conclusions: An intact corneal epithelium serves as an effective barrier against tea-stain discoloration. Only when this layer is disrupted does the damage occur. Therefore, direct application of black tea (Camellia sinensis) to a cornea with an epithelial defect should be avoided.

 

Background: The traditional surgical approach to the excision of persistent urachal remnants is a lower midline laparotomy or semicircular infraumbilical incision.

Objectives: To report our experience with laparoscopic/open urachus excision as a minimally invasive diagnostic and surgical technique.

Methods: This was a retrospective study involving patients who were diagnosed with persistent urachus and underwent laparoscopic/open excision. The morbidity, recovery, and outcomes of surgery were reviewed.

Results: Eight patients (males:females 6:2) with an age range of 1 month to 17 years underwent laparoscopic or open excision (six and two patients respectively). All patients presented with discharge from the umbilicus. Although three patients had no sonographic evidence of a patent urachus, diagnostic laparoscopy detected a patent urachus that was excised laparoscopically. The operative time of laparoscopic surgery ranged from 19 to 71 minutes (the last case was combined with bilateral laparoscopic inguinal hernia repair), and the mean duration of hospital stay was 2.0 ± 0.36 days. Pathological examination confirmed a benign urachal remnant in all cases.

Conclusions: Laparoscopy is a useful alternative for the management of persistent or infected urachus, especially when its presence is clinically suspected despite the lack of sonographic evidence. The procedure is associated with low morbidity, although a small risk of bladder injury exists, particularly in cases of severe active inflammation. 

 

Lung involvement is a well-recognized extra-articular manifestation of ankylosing spondylitis (AS). Anecdotal reports suggest that the use of anti-TNF drugs may be related to lung disease and pulmonary fibrosis. To examine the association between anti-TNF drugs and the development of lung disease in patients with AS or  psoriatic arthritis (PsA) we conducted a systematic review. Of the 670 papers identified by means of key word and hand search, only one full-text paper was considered potentially relevant but had to be discarded as it did not meet the eligibility criteria. Although no conclusion was reached, this is the first systematic review to examine this problem which is becoming increasingly important as these drugs are widely prescribed in patients with spondyloarthritis.
