Background: Low serum albumin is known to be associated with mortality in sepsis, as it reflects effects of nutrition, catabolism, and edema.

Objectives: To examine the association of albumin levels with in-hospital mortality in adults with sepsis, stratified by age groups.

Methods: This nationwide retrospective cohort study comprised patients admitted with sepsis to intensive care units in seven tertiary hospitals during 2003–2011. Only patients with available serum albumin levels at hospital admission and one week after were included. Patients with an intra-abdominal source of sepsis were excluded. The association between sepsis and mortality was analyzed using multivariate logistic regression models.

Results: The study included 3967 patients (58.7% male, median age 69 years). Mean serum albumin levels were 3.1 ± 0.7 g/dl at admission and 2.4 ± 0.6 g/dl one week later. In a multivariate logistic regression model, serum albumin one week after admission was inversely associated with in-hospital mortality (odds ratio [OR] 0.64, 95% confidence interval 0.55–0.73 per 1 g/dl). In an age-stratified analysis, the association was stronger with younger age (OR 0.44 for patients aged < 45 years, 0.60 for patients aged 45–65 years, and 0.67 for patients aged > 65 years). Serum albumin on admission was not associated with in-hospital mortality.

Conclusions: The decline in serum albumin one week after admission is a stronger predictor of mortality in younger patients. Older patients might have other reasons for low serum albumin, which reflect chronic co-morbidity rather than acuity of disease.

Background: Neutrophil-to-lymphocyte ratio (NLR) is a simple and cost-effective marker of inflammation. This marker has been shown to predict cardiac arrhythmias, progression of valvular heart disease, congestive heart failure decompensation, acute kidney injury, and mortality in cardiovascular patients. The pathologic process of aortic stenosis includes chronic inflammation of the valve and therefore biomarkers of inflammation might offer additive prognostic value.

Objectives: To evaluate NLR and its association with long term mortality in transcatheter aortic valve implantation (TAVI) patients.

Methods: We evaluated data of 1152 consecutive patient from the Tel Aviv Medical Center TAVI registry who underwent TAVI. Data included baseline clinical, demographic, and echocardiographic findings; procedural complications; and post-procedure mortality. Patients were compared by using the median NLR value (4.1) and evaluated for long-term mortality.

Results: Patients with NLR above the median had higher mortality rates (26.4% vs. 16.3%, P < 0.001) at 3 years post-procedure. A multivariable analysis found NLR to be an independent risk factor for mortality (hazard ratio = 1.47, 95% confidence interval 1.09–1.99, P = 0.013). In addition, high NLR was linked to complicationsduring and after the procedure.

Conclusion: NLR is an independent prognostic marker among TAVI patients. This marker may represent an increased inflammatory response and should be added to previous known prognostic factors.

Background: Adequate dietary habits and physical activity during childhood and adolescence may promote growth and cognitive development and contribute to the prevention of chronic disease in later life. School is considered an important social environment that can promote healthy eating habits and life-style changes.

Objectives: To evaluate the effects of a school-based intervention on nutritional knowledge, eating habits, and physical activity of adolescents.

Methods: We conducted a prospective questionnaire-based study. Anonymous questionnaires were administered at the beginning of the academic year (September 2014) in one high school. During the following year, vending machines containing milk products were installed within the school facility, and students were given two informative nutrition lectures regarding proper nutrition for age, calcium requirement and importance, and physical activity. One active sports day was initiated. At the beginning of the following academic year (September 2015), the students completed the same questionnaires.

Results: The study was comprised of 330 teenagers, mean age 15.1 ± 1.39 years, 53% males. Response rate was 83.6% ± 0.4% to multiple choice questions, 60.7% ± 0.5% to multiple section tables, and 80.3% ± 0.9% to open questions. Post-intervention, respondents reported an increase in eating breakfast (57% vs. 47.5%, P = 0.02) and a decrease in purchasing food at school (61.6% vs. 54.3%, P = 0.03). No changes were observed in consumption of milk products, knowledge regarding calcium and vegetable consumption, or sports activities.

Conclusions: Short-term high school-based interventions may lead to improvements in eating habits but are not sufficient for changing nutritional knowledge and physical activity

Background: Hip fractures in elderly patients are a major cause of morbidity and mortality. Variability in length of hospital stay (LOS) was evident in this population. The coronavirus disease-2019 (COVID-19) pandemic led to prompt discharge of effected patients in order to reduce contagion risk. LOS and discharge destination in COVID-19 negative patients has not been studied.

Objectives: To evaluate the LOS and discharge destination during the COVID-19 outbreak and compare it with a similar cohort in preceding years.

Methods: A retrospective study was conducted comparing a total of 182 consecutive fragility hip fracture patients operated on during the first COVID-19 outbreak to patients operated on in 2 preceding years. Data regarding demographic, co-morbidities, surgical management, hospitalization, as well as surgical and medical complications were retrieved from electronic charts.

Results: During the pandemic 67 fragility hip fracture patients were admitted (COVID group); 55 and 60 patients were admitted during the same time periods in 2017 and 2018, respectively (control groups). All groups were of similar age and gender. Patients in the COVID group had significantly shorter LOS (7.2 ± 3.3 vs. 8.9 ± 4.9 days, P = 0.008) and waiting time for a rehabilitation facility (7.2 ± 3.1 vs. 9.3 ± 4.9 days, P = 0.003), but greater prevalence of delirium (17.9% vs. 7% of patients, P = 0.028). In hospital mortality did not differ among groups.

Conclusions: LOS and time to rehabilitation were significantly shorter in the COVID group. Delirium was more common in this group, possibly due to negative effects of social distancing.

Background: Flexible flatfoot (FF) is a common foot deformity that can often consist of foot pain. Surgical treatment is designed to lengthen the lateral column.

Objectives: To resolve whether radiographic standing feet measurements of normo-plantigrade feet and FF, symptomatic or not, differ and to determine whether the lateral column is shorter.

Methods: The study comprised 72 patients (127 feet) consecutive patients, 18 years of age and older, who were divided into three groups: normal feet (56), asymptomatic FF (29), and symptomatic FF (42). All patients had a standing anterior posterior (AP) and lateral radiographs. AP images were used for the measurement of the talocalcaneal angle, talar-1st metatarsal angle, and talonavicular coverage. Lateral X-rays were used to estimate the talocalcaneal angle, talar-1st metatarsal angle, calcaneal pitch, naviculocuboid overlap, and column ratio.

Results: All three of the AP radiograph measurements differed among groups, and higher values were measured in the symptomatic FF group. Post hoc analysis found that the talonavicular coverage and the talocalcaneal angles also differed between symptomatic and asymptomatic FF patients. While some lateral measurements differed within groups, only the lateral talar-1st metatarsal angle distinguished between asymptomatic and symptomatic patients. The lateral column length was not found to be shorter among FF patients, weather symptomatic or not.

Conclusions: Only the talonavicular coverage, the AP talocalcaneal, and the lateral talar-1st metatarsal angles were found to differ between asymptomatic and symptomatic FF patients. The lateral column was not found to be shorter

Background: The collapse of the Syrian healthcare system during the civil war led numerous citizens to cross the Syrian–Israeli border to seek medical care.

Objectives: To describe the epidemiology of peripheral nerve injuries (PNIs) sustained in war, their management, and short-term outcomes.

Methods: A retrospective case series study was conducted on 45 consecutive patients aged 25.7 ± 9.3 years. These patients were referred to the hand surgery unit of the department of orthopedic surgery and traumatology at Galilee Medical Center between December 2014 and June 2018. Median time between injury and presentation was 60 days. Injury pattern, additional injuries, surgical findings and management, complications, and length of hospital stay were extracted from medical records.

Results: Most injuries were blast (55.6%) followed by gunshot injuries (37.8%). There were 9 brachial plexus injuries, 9 sciatic nerve injuries, and 38 PNIs distal to the plexus: specifically 20 ulnar, 11 median, and 7 radial nerve injuries. In the latter group, neurotmesis or axonotmesis was found in 29 nerves. Coaptation was possible in 21 nerves necessitating cable grafting in 19. A tendon transfer was performed for 13 peripheral nerves, occasionally supplementing the nerve repair. The patients returned to their country after discharge, average follow-up was 53.6 ± 49.6 days.

Conclusions: For nerve injuries sustained in war, early surgical treatment and providing adequate soft tissue conditions is recommended. Tendon transfers are useful to regain early function.

Background: The coronavirus disease-2019 (COVID-19) crisis has affected how hospitals work and has had an effect on orthopedic surgery.

Objectives: To compare patient management and low-energy and high-energy trauma treatment at two orthopedic trauma units during the COVID-19 crisis and to clarify resource demands and preparedness in orthopedic clinics during the state of emergency caused by the COVID-19 pandemic.

Methods: This retrospective study was conducted at two orthopedic trauma units from 14 March 2019 to 14 April 2019 and from 14 March 2020 to 14 April 2020.

Results: The proportion of patients admitted in the multi-trauma orthopedic unit decreased by one-third, the mean time interval from admission to surgery significantly decreased, and the number of surgeries and mean length of stay in hospital decreased in 2020 compared to the same test period in 2019. In the orthopedic trauma unit, the number of patients and surgeries also decreased.

Conclusions: Our study highlights changes in orthopedic injury characteristics in two orthopedic units during the COVID-19 crisis in Latvia and compares these changes to data from the same time period one year earlier.

Histiocytic sarcoma (HS) is a rare hematopoietic malignancy originating from the monocyte/macrophage bone marrow lineage. HS can occur in isolation or in association with other hematological neoplasms such as non-Hodgkin lymphoma (NHL), myelodysplasia, or acute leukemia. Clinically, HS can affect lymph nodes, gastrointestinal tract, skin, bone marrow, and spleen as well as the central nervous system. Most cases of HS follow an aggressive clinical course, with most patients dying of progressive disease within one year of diagnosis

Background: Sheba Medical Center, Tel Hashomer, is a tertiary hospital located in the center of Israel. It is the largest hospital in Israel and was the first to face coronavirus disease-2019 (COVID-19) patients in the country at the beginning of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic.

Objectives: To describe our experience with the COVID-19 pandemic, focusing on our triage method in the emergency department (ED). Our goal was to keep the main hospitalization buildings clean of infection by separating COVID-19 positive patients from COVID-19 negative patients.

Methods: We divided our ED into two separate sections: a regular non-COVID-19 ED and an advanced biological ED. We created clear protocols of triage for suspected and confirmed COVID-19 patients. We reviewed the data of patients admitted to our ED during the month of March and analyzed the results of our triage method in separating COVID-19 positive from negative patients.

Results: During the month of March 2020, 7957 patients were referred to our ED. Among them 2004 were referred to the biological ED and 5953 were referred to the regular ED. Of the 2004 patients referred to the biological ED, 1641 (81.8%) were sampled for SARS-CoV-2 polymerase chain reaction of whom 143 (8.7%) were positive. Only two COVID-19 positive patients unintentionally entered the main clean hospital, making our triage almost full proof.

Conclusions: Our triage method was successful in separating COVID-19 positive from negative patients and maintained the regular hospital clean of COVID-19 allowing treatment continuation of regular non-COVID-19 patients.

Background: Urinary tract infection (UTI) is a common bacterial infection in children.

Early treatment may prevent renal damage in pyelonephritis. The choice of empiric antibiotic treatment is based on knowledge of the local susceptibility of urinary bacteria to antibiotics. In Israel the recommended empiric oral antibiotic treatment are First or second generation cephalosporin, trimethoprim-sulfamethoxazole or amoxicillin-clavulanic acid.

Objectives: To describe resistance rates of urine bacteria isolated from children with UTI in the community settings. Identify risk factors for resistance.

Methods: A retrospective cross-sectional study of UTI in children aged 3 months to 18 years diagnosed with UTI and treated as outpatients in a large community clinic between 7/2015 and 7/2017 with a diagnosis of UTI.

Results: A total of 989 urinary samples were isolated, 232 were included in the study. Resistance rates to cephalexin, cefuroxime, ampicillin/clavulanate and Trimethoprim-Sulfamethoxazole were 9.9%, 9.1%, 20.7%, and 16.5%, respectively. Urinary tract abnormalities and recurrent UTI were associated with an increase in antibiotic resistance rates. Other factors such as age, fever, and previous antibiotic treatment were not associated with resistance differences.

Conclusions: Resistance rates to common oral antibiotics were low compared to previous studies performed in Israel in hospital settings. First generation cephalosporins are the preferred empiric antibiotics for febrile UTI for outpatient children. Amoxicillin/clavulanate is not favorable due to resistance of over 20% and the broad spectrum of this antibiotic. Care should be taken in children with renal abnormalities as there is a worrying degree of resistance rates to the oral first line antibiotic therapy.

Background: Falls are a common complication in persons with stroke (PwS). Reliable assessment of balance responses to unexpected loss of balance has the potential to identify risk for falls. 

Objectives: To examine inter-observer reliability of balance responses to unannounced surface perturbations in PwS and to explore the concurrent validity of a balance recovery assessment protocol.

Methods: Two observers evaluated balance recovery strategies and fall threshold (a fall into a harness system) in 15 PwS and 15 healthy adults who were exposed to forward, backward, right, and left unannounced surface translations in six increasing intensities while standing. 

Results: Observer agreement was 100% for the fall threshold. Kappa coefficients for step strategies were 0.960–0.988 in PwS and 0.886–0.938 in healthy adults, 0.905–0.988 for arm reactions in PwS and 0.754–0.926 in healthy adults. Significant correlations were found between fall threshold and Berg Balance Scale (r = 0.691), 6-minute walk test (r = 0.599), and fall efficacy scale-international (r= -0.581). 

Conclusions: A trained examiner can reliably classify reactive balance responses to surface perturbations. The high frequency of falls observed in PwS highlights the importance of assessing reactive balance responses to different directions and intensities of surface translations.

Background: Statins and selective serotonin reuptake inhibitors (SSRIs) have beneficial effects on health outcomes in the general population. Their effect on survival in debilitated nursing home residents is unknown.

Objectives: To assess the relationships between statins, SSRIs, and survival of nursing home residents.

Methods: Baseline patient characteristics, including chronic medications, were recorded. The association of 5-year survival with different variables was analyzed. A sub-group analysis of survival was performed according to baseline treatment with statins and/or SSRIs.

Results: The study comprised 993 residents from 6 nursing homes. Of them, 285 were males (29%), 750 (75%) were fully dependent, and 243 (25%) were mobile demented. Mean age was 85 ± 7.6 years (range 65–108). After 5 years follow-up, the mortality rate was 81%. Analysis by sub-groups showed longer survival among older adults treated with only statins (hazard ratio [HR] for death 0.68, 95% confidence intervals [95%CI] 0.49–0.94) or only SSRIs (HR 0.6, 95%CI 0.45–0.81), with the longest survival among those taking both statins and SSRIs (HR 0.41, 95%CI 0.25–0.67) and shortest among residents not taking statins or SSRIs (P < 0.001). The survival benefit remained significant after adjusting for age and after conducting a multivariate analysis adjusted for sex, functional status, body mass index, mini-mental state examination, feeding status, arrhythmia, diabetes mellitus, chronic kidney disease, and hemato-oncological diagnosis.

Conclusion: Treatment with statins and/or SSRIs at baseline was associated with longer survival in debilitated nursing home residents and should not be deprived from these patients, if medically indicated.
