Background: Military medicine has evolved significantly over the past 50 years, advancing from basic treatments and limited evacuations to sophisticated combat casualty care. Innovations such as hemorrhage control, early blood product administration, and telemedicine have greatly improved battlefield care. Rapid evacuation systems and skilled medical teams have reduced mortality and morbidity rates.

Objectives: To review the transformation of the Israel Defense Forces Medical Corps (IDF-MC) in combat casualty care over the past 50 years, focusing on recent applications during the Iron Swords war.

Methods: Data were collected from the personal experiences of IDF-MC doctors, IDF archives, and relevant military medical literature, with an emphasis on life-saving strategies, personnel, equipment, mental health support, and civil–military cooperation.

Results: Rapid evacuation and immediate care have improved survival rates, while increased front-line deployment of medical staff has enhanced response capabilities. Modern medical tools and techniques, such as tourniquets and blood products, have been widely adopted. Improved psychological support strategies ensure better mental health outcomes for soldiers. Enhanced coordination with civilian trauma systems optimizes care and resource allocation, leading to more efficient and effective casualty treatment.

Conclusions: The IDF-MC's advancements in rapid evacuation and front-line medical support have significantly improved combat casualty outcomes. Continued innovation and collaboration with civilian systems are essential for further progress in military medicine. Future technological advancements are anticipated to further enhance military medical care.

Background: Diabetic ketoacidosis (DKA) poses a significant medical emergency in both type 1 (T1DM) and type 2 diabetes mellitus (T2DM) patients. Recent attention has focused on the emergence of euglycemic DKA associated with sodium-glucose cotransporter-2 (SGLT2) inhibitors.

Objectives: To understand the epidemiology and outcomes of DKA, particularly in T2DM patients.

Methods: We conducted a retrospective cohort analysis of 204 patients admitted with DKA to Shamir Medical Center (2013–2021). We assessed demographics, clinical characteristics, and outcomes. Patients were stratified by diabetes type and SGLT2 inhibitor treatment status.

Results: Among the 204 patients with DKA, 38.2% had T2DM. Patients with T2DM exhibited older age, higher co-morbidity burden, and greater prevalence of microvascular complications compared to T1DM patients. Mortality rates were notably higher among T2DM patients, despite similar DKA severity at presentation, including in-hospital mortality rates of 6.4% vs. 0%, P < 0.05, and 90-day mortality rates of 7.7% vs. 0%, P < 0.05. T2DM was independently associated with adverse hospitalization outcomes, including a composite of rehospitalization, prolonged hospital stays, and mortality (odds ratio 2.68, 95% confidence interval 1.302–5.557). SGLT2 inhibitor treatment did not affect hospitalization outcomes of patients with T2DM.

Conclusions: Our findings underscore the importance of recognizing DKA as a substantial complication in diabetic patients, particularly those with T2DM. Vigilance in management, adherence to DKA guidelines, and awareness of triggers such as SGLT2 inhibitors are crucial for improving outcomes in this population.

Background: Clinical toxicology is not a certified specialty in Israel, consequently there are a limited number of toxicologists and toxicology services available for consultation.

Objectives: To establish a medical toxicology consultation service focusing on bedside consultations, which had not previously been available in Israel.

Methods: This single-center, retrospective chart review of toxicology consults was conducted during the first years after the initiation of a new toxicology service.

Results: From September 2017 to December 2021, 1703 toxicology consultations were conducted. The most common exposures and reasons for consultation included psychotropic medications (427, 23%), analgesics and anti-inflammatory medications (353, 19%), household products (312, 17%), substances of abuse (240, 13%), and natural toxins (142, 8%). Bedside medical toxicology consultations were performed in 1036 cases (62%) during daytime and night shifts. The number of consultation requests increased steadily over the study period.

Conclusions: The new toxicology service led to a significant change in the institution’s approach to toxicological patients. A bedside toxicology service could help reduce the healthcare burden on national poison centers and can offer readily available, personalized, medical toxicology care.

Background: Coronary heart disease (CHD) patients are considered high cardiovascular risks. Guidelines recommend low-density lipoprotein cholesterol (LDL-C) target levels below 55 mg/dl with > 50% reduction from baselines. These levels can be reached by a combination of statins, ezetimibe, and anti-protein convertase subtilisin/kexin type 9 (anti-PCSK9) agents. Our clinical impression was that CHD patients do not reach LDL-C target levels, despite the wide availability.

Objectives: To evaluate whether hospitalization would result in changes in lipid lowering regimens and short-term compliance.

Methods: We conducted a retrospective cohort study using data of CHD patients who were admitted to internal medicine wards at Clalit Health Services medical centers because of anginal syndrome during 2020–2022. The data were evaluated for demographic and clinical characteristics; LDL-C level at admission, 6 months previously, and 3 months and 6–9 months after discharge; rates of reaching LDL-C target levels; and lipid lowering treatment at admission, discharge, and 6–9 months after.

Results: The cohort included 10,540 patients. One-third and three-quarters did not have lipids level measurements up to 6 months before and during hospitalization, respectively. Only one-fifth of the patients reached LDL-C values before and during admission (median LDL-C 72 mg/dl; range 53–101). Approximately half were treated with high-dose potent statins. Only 10% were treated with ezetimibe. Hospitalization did not have a clinically significant effect on short-term lipid lowering treatment or LDL-C levels.

Conclusions: Gaps were noted between guidelines and clinical practice for reaching LDL-C target levels. Further education and strict policy are needed.

Background: Heart failure (HF) is an emerging pandemic associated with increased mortality, recurrent hospitalizations, and reduced quality of life. Guideline-directed medical therapy has been shown to improve outcomes, particularly in patients with HF with reduced ejection fraction (HFrEF). The main goal of HF clinics is optimizing medical therapy.

Objectives: To assess the impact of our HF clinic on medical therapy and clinical outcomes.

Methods: We obtained demographic, echocardiographic, and clinical data of patients listed in our HF clinic during a 4-year period. Medical therapy was evaluated based on patient reports and documented data. Recurrent admissions for HF were documented.

Results: A total of 317 patients (74.1% male, median age 66 years, IQR 55–74) were listed in the clinic with a total of 1140 visits. Of these patients, 62.5% had HFrEF, 20.5% presented with mildly reduced ejection fraction, and 17% showed preserved ejection fraction at the time of the first visit. The use of sodium glucose co-transporter 2 inhibitors and mineralocorticoid receptor antagonists was optimized in 92% and 91% of the patients, respectively. In the subgroup of patients with HFrEF, the use of angiotensin-receptor antagonist/neprilysin inhibitor increased from 22.6% to 87.9% (P < 0.001) and SGLT2 inhibitor use increased from 49.2% to 92% (P < 0.001). During the follow-up period (2.2 years, IQR 1.1–3.1), 203 patients (64%) were readmitted to the hospital for HF at least once. The rate of readmissions decreased over time.

Conclusions: An HF clinic plays an important role in optimizing medical therapy and reducing readmissions.

The emergence of the hybrid hospital represents a paradigm shift, blending the physical and virtual realms to optimize healthcare delivery. Telehealth made its significant entrance into the health systems during the coronavirus disease 2019 (COVID-19) pandemic. The use of a variety of telehealth initiatives increased during the COVID-19 pandemic. Approximately 8% of primary care visits in the United States are by telehealth. Despite the rapid growth of telehealth, several barriers persist. Technological limitations, regulatory challenges, and resistance to change among both healthcare providers and patients pose hurdles to the widespread adoption of telehealth services. A significant concern in the healthcare digital evolution is the digital divide. Socioeconomic factors, such as limited access to high-speed internet and digital devices, can exacerbate existing healthcare disparities. An important part of the hybrid hospital is home hospitalization, which is an alternative to regular hospitalization. This method opens access to big, tertiary, academic centers to remote populations and advances treatment equity. Home hospitalization has become available in several countries such as Australia, China, and the United States, with impressive results for peripheral, remote populations. According to the McKenzie Report, virtual hospitals have the potential to ease busy health systems, make more hospital beds available, decrease the need for building physical hospitals, and save millions of dollars. Hybrid hospitals and telehealth are here to stay. The medical community should study the risks and opportunities and establish guidelines for proper, quality, and safe management.

Background: Exclusive breastfeeding is recommended through six months as it supports infant growth and development. Yet, many mothers do not exclusively breastfeed in early postpartum.

Objectives: To examine factors associated with exclusive breastfeeding at hospital discharge among culturally diverse women.

Methods: This cross-sectional study used data of women who gave birth at a major medical center in Israel in 2015–2017. Descriptive statistics and regression analysis were conducted to examine maternal characteristics and associated breastfeeding outcomes by hospital discharge.

Results: Among 10,978 women, 17.8% (n=1958) exclusively breastfed, 57.9% (n=6357) partially breastfed, and 24.3% (n=2663) did not breastfeed. Among Israeli-born and former Soviet Union-born Jewish women, breastfeeding intention (odds ratio [OR] 19.59, 95% confidence interval [95%CI] 10.27–37.35 and OR 15.92, 95%CI 5.79–43.80, respectively) and early breastfeeding (OR 2.415, 95%CI 1.91–3.05 and OR 2.04, 95%CI 1.57–2.64, respectively) were associated with exclusive breastfeeding. The only significant factor associated with exclusive breastfeeding among refugees and Israeli-born Muslim women was early breastfeeding (OR 1.61, 95%CI 1.20–2.16). For Ethiopian-born Jewish women, not married (OR 0.330, 95%CI 0.114–0.955) and cesarean delivery (OR 0.481, 95%CI 0.232–0.998) were negatively associated with exclusive breastfeeding.

Conclusions: Despite having access to the same hospital-based breastfeeding support, there were differences among ethno-culturally diverse women in Israel. In this study, we identified maternal characteristics associated with early breastfeeding among women of diverse ethno-cultural backgrounds. Study findings highlight the importance of ethno-cultural considerations in breastfeeding practices and inform health professionals of factors associated with exclusive breastfeeding in early postpartum.

Background: Cases of second trimester pregnancy loss can be treated either pharmacologically or by surgical evacuation. Misoprostol, an E1-prostaglandin analog, is used to facilitate the evacuation of the uterus.

Objectives: To determine the risk factors associated with patients who were treated with five or more repeated doses of misoprostol.

Methods: We conducted a retrospective study of patients treated with vaginal misoprostol at our institution between December 2016 and October 2021 for second trimester pregnancy loss.

Results: In total, 114 patients were eligible for analysis; 83 were treated with < 5 doses and 31 with ≥ 5. We recorded each case in which repeated doses were administered, irrespective of predetermined conditions such as gravidity, parity, maternal age, or gestational age. Moreover, cases of five or more misoprostol dosing were not associated with an increased complications rate, except for the increased duration of hospitalization (3.1 vs. 2.2 days, P-value < 0.01).

Conclusions: Repeated dosing could not be predicted before treatment among those treated with vaginally administered misoprostol for second trimester pregnancy loss. However, low complication rates of repeated dosing may reassure both physicians and patients regarding safety, efficacy, and future fertility.

Background: Hip fractures are a public health problem that disproportionately affects the elderly. Displaced femoral neck fractures were treated historically with hemiarthroplasty, but the use of total hip arthroplasty (THA) is increasing showing superior long-term results.

Objectives: To assess whether THA has superior short-term results compared to bipolar hemiarthroplasty for displaced femoral neck fractures.

Methods: Two groups of active older patients underwent either cementless bipolar hemiarthroplasty or THA for displaced femoral neck fracture. All patients were operated on using the direct lateral approach to the hip joint. Patients were assessed using the Harris Hip Score at hospital discharge and at 6 weeks follow-up.

Results: We included 40 patients ages 65–85 years; 18 underwent bipolar hemiarthroplasty and 22 THA. The number of women in each group was similar, as was mean age: 73.1 ± 4.2 years in the hemiarthroplasty group and 71.0 ± 3.7 in THA. Harris Hip Score on hospital discharge was similar in both groups. Walking ability at discharge was better in the THA cohort and they were discharged sooner: 5.2 ± 1.3 vs. 6.4 ± 1.7 days following hemiarthroplasty (P = 0.021). At 6 weeks follow-up, the mean Harris Hip Score was higher in the THA group (78.6 ± 11 vs. 61.5 ± 17 for hemiarthroplasty, P < 0.001). Patients in the THA group walked longer distances, needed less support while walking, and reported less pain.

Conclusions: Better short-term results at hospital discharge and at 6 weeks follow-up after THA contributed to earlier patient independence and shorter hospital stays.

Background: At the beginning of 2020, the coronavirus disease 2019 (COVID-19) pandemic presented a new burden on healthcare systems.

Objectives: To evaluate the impact of the COVID-19 pandemic on the outcome of non-COVID patients in Israel.

Methods: We conducted a retrospective observational cohort study at a tertiary medical center in Israel. From December 2018 until June 2022, 6796 patients were hospitalized in the internal medicine wards. Patients were grouped based on their admission date: admitted during COVID waves (waves group), admitted between waves (interim group), and admitted during the same months in the previous year (former-year group).

Results: Mortality during hospitalization and 30-day mortality were higher in the waves group compared to the interim and former-year groups (41.4% vs. 30.5% and 24%, 19.4% vs. 17.9% and 12.9%, P < 0.001). In addition, 1-year mortality was higher in the interim group than in the waves and former-year group (39.1 % vs. 32.5% and 33.4%, P = 0.002). There were significant differences in the readmissions, both at 1 year and total number. The waves group had higher rates of mechanical ventilation and noradrenaline administration during hospitalization. Moreover, the waves group exhibited higher troponin levels, lower hemoglobin levels, and more abnormalities in liver and kidney function.

Conclusions: Hospitalized non-COVID patients experienced worse outcomes during the peaks of the pandemic compared to the nadirs and the preceding year, perhaps due to the limited availability of resources. These results underscore the importance of preparing for large-scale threats and implementing effective resource allocation policies.

Background: Influenza and coronavirus disease 2019 (COVID-19) are respiratory diseases with similar modes of transmission. In December 2021, influenza re-emerged after it had been undetected since March 2020 and the Omicron variant replaced the Delta variant. Data directly comparing the two diseases are scarce.

Objectives: To compare the outcomes of patients with both the Omicron variant and influenza during 2021–2022.

Methods: We performed a retrospective study conducted in Beilinson hospital, Israel, from December 2021 to January 2022. We included all hospitalized patients with either laboratory-confirmed COVID-19 or influenza. The primary outcome was 30-day mortality.

Results: We identified 167 patients diagnosed with Omicron and 221 diagnosed with Influenza A. The median age was 71 years for Omicron and 65 years for influenza. Patients with Omicron had a significantly higher Charlson Comorbidity Index score (4 vs. 3, P < 0.001). Patients with Omicron developed more respiratory failure that needed mechanical ventilation (7% vs. 2%, P = 0.05) and vasopressors (14% vs. 2%, P < 0.001) than patients with influenza. In a multivariate model, 30-day mortality was lower in patients diagnosed with influenza than in patients diagnosed with Omicron (19/221 [9%] vs. 44/167 [26%], hazard ratio 0.45, 95% confidence interval 0.25–0.81).

Conclusions: Patients diagnosed with Omicron had higher mortality than patients diagnosed with seasonal influenza. This finding could be due to differences in co-morbidities, the virus pathogenicity, and host responses to infection.

Background: While several studies have noted smell impairment in schizophrenia, it is unclear whether this impairment extends to acute psychosis and whether it is associated with more severe illness as expressed in extended hospitalization.

Objectives: To evaluate the olfactory function of patients in an acute psychotic state and correlate it with clinical symptomatology and length of hospitalization.

Methods: Olfactory function was assessed in 20 patients with schizophrenia in their first week of hospital admission for acute psychosis compared with matched controls. Olfaction was evaluated via three stages: threshold, discrimination, and identification of different odors utilizing the Sniffin' Sticks test battery.

Results: Schizophrenia patients scored significantly lower on total smell score, discrimination, and identification abilities. A significant association was observed between hospitalization duration and total smell score and smell discrimination. No significant associations between smell and clinical symptomatology were observed.

Conclusions: Study observations confirm impaired sense of smell in schizophrenia patients and suggest that smell impairment may be a potential marker of more serious illness as expressed in longer hospital stay.

Background: Infants younger than 6 months of age are not eligible for coronavirus disease 2019 (COVID-19) vaccinations. Maternal variables during pregnancy and the postnatal period may affect the clinical and laboratory course of COVID-19 positive infants.

Objective: To assess the clinical manifestation and laboratory differences in infants with three maternal variables: breastfeeding, vaccinated, and co-illness.

Methods: We conducted a single-center retrospective cohort study of positive COVID-19 infants with three subgroups of maternal variables. The population included infants under 6 months of age hospitalized due to COVID-19. Data about clinical features, laboratory tests, and maternal information including vaccination status, breastfeeding status and maternal positive COVID-19 infection was gathered. All variables were compared among the three subgroups.

Results: Breastfed infants had shorter hospitalization period (mean 2.61 ± 1.378 days) compared to non-breastfed infants (mean 3.8 ± 1.549) (P = 0.051). COVID-19 infants of positive COVID-19 mothers had a higher absolute neutrophil count (mean 4.4 ± 3.8) compared to infants of COVID-19 negative mothers (mean 2.7 ± 2.4) (P = 0.042).

Conclusion: Breastfeeding was associated with shorter periods of hospitalization in COVID-19 positive infants. In addition, positive COVID-19 infants of mothers who were positive for COVID-19 are likely to have a higher absolute neutrophils count.

Background: The evaluation of syncope in emergency departments (EDs) and during hospitalization can be ineffective. The European Society of Cardiology (ESC) guidelines were established to perform the evaluation based on risk stratification.

Objectives: To investigate whether the initial screening of syncope adheres to the recent ESC guidelines.

Methods: Patients with syncope who were evaluated in our ED were included in the study and retrospectively classified based on whether they were treated according to ESC guidelines. Patients were divided into two groups according to the ESC guideline risk profile: high risk or low risk.

Results: The study included 114 patients (age 50.6 ± 21.9 years, 43% females); 74 (64.9%) had neurally mediated syncope, 11 (9.65%) had cardiac syncope, and 29 (25.45%) had an unknown cause. The low-risk group included 70 patients (61.4%), and the high-risk group included 44 (38.6%). Only 48 patients (42.1%) were evaluated according to the ESC guidelines. In fact, 22 (36.7%) of 60 hospitalizations and 41 (53.2%) of 77 head computed tomography (CT) scans were not mandatory according to guidelines. The rate of unnecessary CT scans (67.3% vs. 28.6%, respectively, P = 0.001) and unnecessary hospitalization (66.7% vs. 6.7%, respectively, P < 0.02) were higher among low-risk patients than high-risk patients. Overall, a higher percentage of high-risk patients were treated according to guidelines compared to low-risk patients (68.2% vs. 25.7% respectively, P < 0.0001).

Conclusions: Most syncope patients, particularly those with a low-risk profile, were not evaluated in accordance with the ESC guidelines.
