Background: Bloodstream infections (BSI) are associated with high morbidity and mortality. Inappropriate empirical antimicrobial therapy leads to poor outcomes.

Objectives: To evaluate the impact of clinical pharmacist intervention on the appropriateness of antibiotic treatment in patients hospitalized with bacteremia.

Methods: A retrospective study was conducted at the Soroka Medical Center in Israel. The intervention was implemented starting in July 2018. We compared 170 patients who received pharmacist intervention (August 2018 to June 2019) to 173 control patients (January 2017 to July 2018). The primary outcome was a composite of appropriate antibiotic choice and dosage.

Results: Pharmacist intervention significantly improved appropriate antibiotic dosing (97.6% vs. 91.3%, P = 0.011) and selection based on pathogen sensitivity (100% vs. 95.4%, P = 0.007). The most significant effect was observed in patients with intermediate renal function (CrCl 30–60 ml/min). Multivariate analysis confirmed pharmacist intervention as a strong predictor of appropriate treatment (odds ratio 5.00, 95% confidence interval 1.64–15.25, P = 0.005). The intervention group had longer hospital stays (median 15 vs. 9 days, P < 0.001) and lower 7-day relapse rates (2.4% vs. 8.7%, P = 0.010).

Conclusions: Clinical pharmacist interventions significantly improved the appropriateness of antibiotic treatment in patients with bacteremia, particularly in those with intermediate renal function. Despite longer hospital stays, the intervention group had lower early relapse rates than the control group. These findings support the integration of clinical pharmacists into antimicrobial stewardship programs.

Liver transplantation (LT) remains the only definitive treatment for most types of liver failure. However, it is considered a highly technically complex surgery performed in a critically ill patient population and is, hence, associated with significant morbidity and mortality. Peroneal neuropathy with foot drop has been intermittently reported as a complication following LT, with an incidence ranging from 1.4% to 13.3% [1-4]. This debilitating condition is characterized by an inability to lift the forefoot due to paralysis or significant weakness of the dorsiflexor muscles. While it may not appear to be a serious complication, it can significantly impair gait, increase the risk of falls, and ultimately affect ambulation and the ability to perform daily activities [5].

In this case communication, we described two cases of foot drop following LT at Rabin Medical Center (Beilinson Campus), Petah Tikva, Israel. Our research joins a growing body of evidence and raises awareness about foot drop as an underreported yet debilitating complication. It underscores the importance of increased vigilance and describes our preventive measures adopted to reduce future incidents.

Background: Peripartum cardiomyopathy (PPCM) is a rare but potentially devastating complication of pregnancy. Although the pathophysiology of PPCM is not fully understood, there are known risk factors for developing PPCM, which are maternal and gestation related. In the first wave of the coronavirus disease 2019 (COVID-19) pandemic, we witnessed an elevated incidence of PPCM among COVID-19 survivors.

Objectives: To present a single-center case series of three patients diagnosed with peripartum cardiomyopathy after recovered from COVID-19 during the index pregnancy.

Methods: In this single center case study, all patients diagnosed with PPCM at our institute during the examined time frame were included. Electronic medical records were studied.

Results: Three patients previously diagnosed with asymptomatic or mildly symptomatic COVID-19 disease during pregnancy presented with PPCM before or shortly after delivery. Patients underwent testing to rule out residual COVID-19 myocarditis, were treated pharmacologically and with wearable defibrillators as needed, and were examined in follow-up 1–9 months after delivery.

Conclusions: Residual endothelial damage due to COVID-19 disease, even if originally mild in presentation, could predispose pregnant patients to PPCM and should be considered as a risk factor when assessing patients with new onset symptoms of heart failure. Further research is needed to confirm this hypothesis and fully determine the underlying pathophysiology. These preliminary findings warrant a high index of suspicion for PPCM in COVID-19 recoverers.

Background: The lack of organs for liver transplantation has prompted transplant professionals to study potential solutions, such as the use of livers from donors older than 70 years. This strategy is not widely accepted because potential risks of vascular and biliary complications and recurrence of hepatitis C.

Objectives: To examine the efficacy and safety of liver grafts from older donors for transplantation.

Methods: A retrospective analysis of data on 310 adults who underwent deceased donor liver transplantation between 2005 and 2015 was conducted. We compared graft and recipient survival, as well as major complications, of transplants performed with grafts from donors younger than 70 years (n=265, control group) and those older than 70 years (n=45, older-donor group), followed by multivariate analysis, to identify risk factors.

Results: There was no significant difference between the control and older-donor group at 1, 5, and 10 years of recipient survival (79.5% vs. 73.3%, 68.3% vs. 73.3%, 59.2% vs. 66.7%, respectively) or graft survival (74.0% vs. 71.0%, 62.7% vs. 71.0%, 54.8% vs. 64.5%, respectively). The rate of biliary and vascular complications was similar in both groups. Significant risk factors for graft failure were hepatitis C (hazard ratio [HR] = 1.92, 95% confidence interval [95%CI] 1.16–2.63), older donor age (HR = 1.02, 95%CI 1.007–1.031), and male gender of the recipient (HR = 1.65, 95%CI 1.06–2.55).

Conclusion: Donor age affects liver graft survival. However, grafts from donors older than 70 years may be equally safe if cold ischemia is maintained for less than 8 hours.

Background: Little is known about the incidence of urinary tract infections (UTI) in the dispersed Bedouin population. UTIs are routinely treated empirically according to local resistance patterns, which is important when evaluating the risk factors and antibiotic resistance patterns in the Bedouin population.

Objectives: To analyze risk factors, pathogens, and antibiotic resistance patterns of UTIs in the Bedouin population compared to the general population in southern Israel. To compare data from this study to that from a previous study conducted at our center.

Methods: We prospectively followed all patients hospitalized with community acquired UTIs during a 4 month period at Soroka Medical Center. We also compared results from this study to those from a study conducted in 2000.

Results: The study comprised 223 patients: 44 Bedouin (19.7%), 179 (80.3) non-Bedouin; 158 female (70.9%), 65 male (29.1). The Bedouin were younger (51.7 vs. 71.1 years of age, P < 0.001) and had a lower Charlson Comorbidity Index (2.25 vs. 4.87, P < 0.001). Enterobacteriaceae were the most common pathogens identified, and Escherichia coli (E. coli) was the most common with 156 (70%) strains identified, followed by Klebsiella spp. with 29 (13%), Proteus spp. with 18 (8%), pseudomonas with 9 (4%), and other bacteria including enterococci with 11 (5%). The prevalence of E. coli increased significantly from 56% in 2000 to 70% in this study. We also noted an increase in community acquired extended spectrum beta lactamase (ESBL) pathogens from 4.5% in 2000 to 25.5% in the present study. No statistically significant difference was observed between the Bedouin and general populations in the causal pathogens, resistance to antibiotics, length of therapy, and readmission rate within 60 days. 

Conclusions: The Bedouin population hospitalized for UTIs is younger and presents with fewer co-morbidities. Isolated pathogens were similar to those found in the general population as was the presence of drug resistant infections. Overall, a substantial percentage of pathogens were resistant to standard first-line antibiotics, driving the need to change from empiric therapy to aminoglycoside therapy.

Background: Reports of lamellar macular holes (LMHs) with underlying age-related macular degeneration (AMD) are rare and the specific definition, pathogenesis, and surgical recommendations for this macular condition remain unclear.


Objectives: To present a series of LMHs in eyes with underlying end-stage AMD, and describe optical coherence tomography (OCT) detection of associated morphologic abnormalities.


Methods: We reviewed the files of consecutive patients diagnosed with LMH and underlying end-stage AMD between September 2007 and September 2011. 


Results: Sixteen eyes of 14 patients were included in this study. The average follow-up after the OCT-established diagnosis of LMH was 19.8 months (range 4–48). The average visual acuity (VA) at last follow-up visit was 20/400 (20/60–20/1200). The best-corrected VA was stable in 10 eyes (62.5%) and deteriorated in 6 (37.5%). There was a statistically significant correlation between VA and minimal foveal thickness (r = -0.598, P = 0.014).


Conclusions: In this series of LMHs with underlying AMD the OCT findings were intraretinal fluid, cystic spaces and window defect.

Background: Early detection of glaucoma enables early initiation of treatment. Screening populations at risk is likely to help achieve this goal.

Objectives: To increase public awareness regarding early detection of glaucoma, and estimate the prevalence of increased intraocular pressure (IOP) and optic disk cupping in the screened population.

Methods: A public awareness campaign was carried out in Israel during the 2009 and 2010 World Glaucoma Week, culminating each year in a one-day, free-of-charge screening of individuals in 13 outreach public locations. Screening was performed by 45 ophthalmologists and included a brief medical history, slit-lamp exam with measurement of intraocular pressure (IOP), and evaluation of cup/disk ratio.

Results: A total of 2560 individuals were screened; the mean age was 59 ± 13 years. IOP ≥ 21 mmHg was found in 4.8%, and 12.3% had cupping ≥ 0.5. IOP ≥ 21 mmHg together with cupping ≥ 0.5 were present in 1.4% and this rate increased with age: 3.7% of cases in the age group ≥ 70 years compared to 1% and 0.6% in the age groups 50–69 and < 50 years, respectively (P < 0.001). Likewise, the prevalence of cupping ≥ 0.7 and of IOP ≥ 24 mmHg increased significantly with age. The prevalence of IOP ≥ 21 mmHg increased in cases with a family history of glaucoma in first-degree relatives (10.5% compared to 3.9%, P < 0.001). The prevalence of IOP ≥ 21 mmHg was also increased in diabetic patients (8.3% vs. 4.3% in non-diabetics, P = 0.002). Further ophthalmologic evaluation was recommended to 13% of the screened individuals.

Conclusions: Outreach screening for glaucoma is a valuable tool for detecting glaucoma, pre-perimetric glaucoma, or ocular hypertension in a meaningful number of previously undiagnosed cases. Yet, cost-effectiveness issues should also be considered. The yield of such screening increases with age and seems to be most advantageous in cases with diabetes or a family history of glaucoma.

Giant cell arteritis (GCA) is considered to be a T cell-dependent disease. Autoantibodies have not consistently been found in GCA. The exception is antiphospholipid antibodies (APLA), which were found in 30–80% of GCA cases. Recently, efforts have been made to seek autoantibodies in GCA using newer methods of detection: serological identification of antigens by recombinant cDNA expression cloning, and a proteomic approach. In these studies, lamin C (a nuclear envelope antigen) was recognized by antibodies in 32% of GCA sera and none of the controls. Other autoantigenic proteins were also identified: lamin A, vinculin (a cytoskeleton antigen), and annexin 5 (an endothelial protein). In a recent study, 92% of 36 patients with GCA and/or polymyalgia rheumatica (PMR) had autoantibodies to a human ferritin peptide (the heavy chain N-terminal); 89% had antibodies to bacterial ferritin peptide of Staphylococcus epidermidis. The significance of these findings needs to be studied further. GCA may be a part of the newly described ASIA syndrome (autoimmune syndrome induced by adjuvants). A recent study from Italy reported 10 cases of GCA/PMR within 3 months of influenza vaccination. These comprised 50% of all cases of GCA/PMR diagnosed during the 6 year period of the study. Another 11 cases of GCA following influenza vaccinations were reported. GCA pathogenesis involves all branches of the immune system, including antigen-presenting cells, T cells and B cells, and autoantibody formation is not uncommon. GCA etiology remains unknown, but may be associated with exposure to bacterial or viral antigens.

 Background: Prolonged working hours and sleep deprivation can exert negative effects on professional performance and health.

Objectives: To assess the relationship between sleep deprivation, key metabolic markers, and professional performance in medical residents.

Methods: We compared 35 residents working the in-house night shift with 35 senior year medical students in a cross-sectional cohort study. The Epworth Sleepiness Scale (ESS) questionnaire was administered and blood tests for complete blood count (CBC), blood chemistry panel, lipid profile and C-reactive protein (CRP) were obtained from all participants.

Results: Medical students and medical residents were comparable demographically except for age, weekly working hours, reported weight gain, and physical activity. The ESS questionnaires indicated a significantly higher and abnormal mean score and higher risk of falling asleep during five of eight daily activities among medical residents as compared with medical students. Medical residents had lower high density lipoprotein levels, a trend towards higher triglyceride levels and higher monocyte count than did medical students. CRP levels and other laboratory tests were normal and similar in both groups. Among the medical residents, 5 (15%) were involved in a car accident during residency, and 63% and 49% reported low professional performance and judgment levels after the night shift, respectively.

Conclusions: Medical residency service was associated with increased sleepiness, deleterious lifestyle changes, poorer lipid profile, mild CBC changes, and reduced professional performance and judgment after working the night shift. However, no significant changes were observed in CRP or in blood chemistry panel. Larger prospective cohort studies are warranted to evaluate the dynamics in sleepiness and metabolic factors over time.
