Background: Fetal weight estimation at term is a challenging clinical task.

Objectives: To evaluate the association between peripheral white blood cell (WBC) count of the laboring women and neonatal birth weight (BW) for term uncomplicated pregnancies.

Methods: We conducted a single-center, retrospective cohort study (2006–2021) of women admitted in the first stage of labor or planned cesarean delivery. Complete blood counts were collected at admission. BW groups were categorized by weight (grams): < 2500 (group A), 2500–3499 (group B), 3500–4000 (group C), and > 4000 (group D). Two study periods were used to evaluate the association between WBC count and neonatal BW.

Results: There were a total of 98,632 deliveries. The dataset analyses showed a lower WBC count that was significantly and linearly associated with a higher BW; P for trend < 0.001 for women in labor. The most significant association was noted for the > 4000-gram newborns; adjusted odds ratio 0.97, 95% confidence interval 0.96–0.98; P < 0.001; adjusted for hemoglobin level, gestational age, and fetal sex. The 2018–2021 dataset analyses revealed WBC as an independent predictor of macrosomia with a significant incremental predictive value (P < 0.0001). The negative predictive value of the WBC count for macrosomia was significantly high, 93.85% for a threshold of WBC < 10.25 × 10³/µl.

Conclusions: WBC count should be considered to support the in-labor fetal weight estimation, especially valuable for the macrosomic fetus.

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.

Background: Hemodialysis requires reliable, recurrent access to the circulatory system. Central venous tunneled dialysis catheters (TDC) are frequently used for patients receiving hemodialysis as a bridge to permanent vascular access or as a final option. TDC are prone to complications such as infection and dysfunction.

Objective: To assess the prevalence and predictors of TDC dysfunction in a cohort of chronic hemodialysis patients.

Methods: This single-center, retrospective study was based on data from an electronic database of chronic hemodialysis patients during 5 years of follow-up.

Results: A total of 625 TDC were inserted in 361 patients, of which 234 (37.4%) were replaced due to dysfunction. The main insertion site was the right internal jugular vein. Diabetes mellitus was an important predictor of TDC dysfunction and was significantly correlated with TDC extraction. Chronic anticoagulation and antiplatelet treatment did not affect the rate of TDC dysfunction or replacement.

Conclusions: TDC use for chronic dialysis patients is increasing and dysfunction is a major problem. In our study, we highlighted the high prevalence of TDC dysfunction and the need for further research to improve hemodialysis access as well as TDC patency and function.

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: Cesarean delivery (CD) is one of the most common surgeries performed worldwide, with increasing yearly rates. Although neuraxial techniques remain the preferred anesthesia method for CD, maternal thrombocytopenia remains a prominent contraindication. Formation of spinal\epidural hematomas are extremely rare, however the minimal thrombocyte count required for safe neuraxial anesthesia is still under debate. Although transfusion of thrombocytes for the purpose of neuraxial anesthesia is still not recommended, patients with severe thrombocytopenia (less than 50 × 10³/uL) are given thrombocyte transfusion for surgical hemostasis.

Objectives: To evaluate the anesthetic approach to caesarean deliveries in parturients with severe thrombocytopenia who received thrombocyte transfusion aimed for improved surgical hemostasis.

Methods: We conducted a single center, retrospective cohort study.

Results: A total of five cases were found, four of which were given spinal anesthesia immediately following thrombocyte transfusion. One patient was denied spinal anesthesia because her thrombocyte count following transfusion failed to reach safe levels. None of our cases had anesthesia-related complications recorded.

Conclusions: We examined the anesthetic management parturients with severe thrombocytopenia who needed cesarean delivery and were transfused with thrombocytes for surgical hemostasis. In such cases, spinal anesthesia may be considered due to the serious risks associated with general anesthesia.

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.

Long-term sperm preservation plays a pivotal role in providing a lifeline for individuals grappling with medical and fertility challenges; thus, enabling them to pursue their aspirations of parenthood. While the significance of frozen sperm is unquestionable, it is vital to address the persistently low utilization and disposal rates of stored samples over time and resulting in an unintended accumulation of unclaimed doses. This accumulation not only carries significant medical, legal, and financial burdens for the institutions responsible, such as sperm banks, but also raises complex ethical considerations, particularly concerning potential biological paternity. These multifaceted considerations are particularly relevant within Israel's publicly funded healthcare system, accentuating the need for clearly defined preservation criteria in cases where an immediate clinical necessity is not readily apparent. We highlight the important clinical, ethical, and economic aspects of preserving the potential for biological paternity and efficiently managing the resources and responsibilities associated with long-term sperm preservation.

A 90-year-old female with a medical history of untreated gout presented to the emergency department with acute low back pain. On physical examination, the area over the 4th lumbar spinous process was extremely tender. Serum C-reactive protein was 184 mg/L, and uric acid was 8.3 mg/dl.

Conventional [Figure 1A] and dual-energy computed tomography (DECT) [Figure 1B] studies of the lumbar spine showed multiple tophi-engulfing posterior vertebral structures of the involved vertebral unit, including the spinous and transverse processes and facet joints. This condition is schematically shown in Figure 1C with asterixis indicating tophi-induced erosion and osteolysis of the spinous process.

The patient was treated for a suspected acute gouty attack with prednisone and colchicine followed by allopurinol treatment with rapid and uneventful recovery.

Axial gout is an underdiagnosed and potentially curable cause of recurrent low back pain [1,2]. Referral to DECT should be considered in patients with uncontrolled gout and concurrent back pain.

The issue of genital ulcers (GUs) in Israeli Arab female patients with Behçet's disease (BD is important as GUs are considered a unique feature of BD and stand as diagnostic criterion for the diagnosis in the International Study Group (ISG) criteria [1] and the International Criteria for Behcet Disease (ICBD) [2]. According to the ISG, GUs can be detected by a physician or by the patient [1]. While oral ulcers are easily observable, the identification of more hidden GUs pose a significant challenge.

Background: Diabetic ketoacidosis (DKA) is an acute metabolic, life-threatening complication of diabetes mellitus with a mortality rate that now stand at less than 1%. Although mortality is coupled with the etiology of DKA, literature on the influence of DKA etiology on patient outcome is scarce.

Objectives: To study different triggers for DKA and their effect on outcomes.

Methods: We conducted a retrospective study that include 385 DKA patients from 2004 to 2017. The study compared demographics, clinical presentation, and mortality rates by different precipitating factors.

Results: Patients with DKA due to infections had a higher risk to develop in-hospital mortality after controlling for age and sex (odds ratio 4.40, 95% confidence interval 1.35–14.30), had a higher Charlson Comorbidity Index score, a higher risk of being mechanical ventilated (14% vs. 3%, P < 0.01), and a longer duration of hospitalization (5 days vs. 3 days, P < 0.001).

Conclusions: It is crucial to find the triggers that precipitate DKA and start the treatment as early as possible in addition to the metabolic aspect of the treatment especially when the trigger is an infectious disease.

Background: Left ventricular assist devices (LVAD) are a staple element in contemporary treatment of advanced heart failure. LVAD surgeries are mostly done in heart transplantations centers, as a destination therapy or as a bridge to heart transplantation.

Objectives: To describe our step-by-step experience in establishing and implementing a new LVAD program in a non-heart transplant center. To give insight to our short- and long-term results of our first 25 LVAD patients.

Methods: Preliminary steps included identifying the need for a new program and establishing the leading team. Next is defining protocols for pre-operative evaluation, operating room, post-operative management, and outpatient follow-up. The leading team needs to educate other relevant units in the hospital that will be involved in the care of these patients. It is essential to work in collaboration with a heart transplant center from the very beginning. Patient selection is of major importance especially in the early experience. Initially “low risk” patients should be enrolled.

Results: We describe our first 25 LVAD patients. Our first five patients all survived beyond 2 years, with no major complications. Overall, there was one operative death due to massive GI bleeding. There were four late deaths due to septic events.

Conclusions: Establishing a new LVAD program can be successful also with small- and medium-size programs. With careful and meticulous planning LVAD implantation can be extended to more centers thus offering an excellent solution for advanced heart failure patients.

Background: Although minimally invasive surgery for Crohn’s disease has been validated in previous studies, most of those reports have referred to laparoscopic-assisted procedures with an extra-corporeal anastomosis.

Objectives: To evaluate the short- and long-term outcomes of total laparoscopic ileocolic resection with an intracorporeal anastomosis for Crohn’s disease patients.

Methods: We conducted a single-center retrospective review of all patients who underwent primary ileocolic resection for Crohn’s disease between 2010 and 2021. Group A included 34 patients who underwent total laparoscopic ileocolic resection with intracorporeal anastomosis. Group B comprised 144 patients who underwent an open or laparoscopic-assisted procedure.

Results: No differences were noted in operative time (mean 167 minutes vs. 152 minutes, P = 0.122), length of stay (median 6.4 days vs. 7.5 days, P = 0.135), readmission rates (11.8% vs. 13.2%, P = 1), and microscopic involvement of surgical margins (7.7% vs. 18.5%, P = 0.249). Group A had significantly fewer postoperative surgical site infections (2.9% vs. 22.2% respectively, P = 0.013), with no differences in other complications prevalence. After a median follow-up of 46 months, there were similar rates of endoscopic recurrence (47.1% vs. 51.4%, P = 0.72), clinical recurrence (35.3% vs. 47.9%, P = 0.253), and surgical recurrence (2.9% vs. 4.9%, P = 0.722).

Conclusions: Total laparoscopic ileocolic resection with intracorporeal anastomosis for Crohn’s disease is safe and resulted in favorable outcomes in terms of postoperative wound healing. The long-term disease recurrence rates were like those of laparoscopic-assisted and open ileocolic resection.

Background: Immunoglobulin G4-related disease (IgG4-RD) is a chronic, immune-mediated condition characterized by fibro-inflammatory lesions with lymphoplasmacytic infiltration. Diagnosis traditionally relies on histopathological findings, including the presence of IgG4+ plasma cells. However, due to challenges in biopsy accessibility, additional measures are needed to facilitate diagnosis.

Objectives: To identify additional parameters for characterizing IgG4-RD patients.

Methods: We compared several circulating factors between a cohort of patients with IgG4-RD disease seen at our hospital between 2017 and 2023 and healthy controls.

Results: Among 16 suspected patients, 13 were confirmed to have IgG4-RD, and 3 were classified as highly likely. Comparison with controls revealed differences in white blood cell count (WBC) (Folf change (FC) 1.46, P < 0.05), plasmablasts (FC 3.76, P< 0.05), plasmablasts CD38 (FC 1.43, P < 0.05), and CD27 (FC 0.66, P = 0.054), thus highlighting potential markers for IgG4-RD diagnosis. Treatments with steroids/rituximab tend to reduce plasmablast (FC 0.6) and IgG4 (FC 0.28) levels and to increase Gal-3 levels.

Conclusions: Levels of plasmablasts are a significant diagnostic feature in IgG4-RD. Healthy individuals have a lower level of plasmablasts. Elevated Gal-3 in serum of patients with IgG4-RD suggests a role in plasmablast activation. CD38/CD27 expression by plasmablasts emerges as a potential marker. Further research on a larger cohort is needed to confirm these findings.

Late arrival ST-segment elevation myocardial infarction (STEMI) is defined as a patient-related delay > 12 hours. It is estimated to represent a significant portion of STEMI patients. As reflected by society guidelines, this group of patients impose great therapeutic challenge, namely due to controversy in the literature regarding optimal care, together with major adverse clinical outcomes [1]. In addition to a possible myocardial infarction (MI), mechanical complications include ventricular septal defect (VSD), left ventricular (LV) free wall, or papillary muscle rupture. Prompt diagnosis and intervention are crucial to improve outcomes as post-infarction ventricular septal defect (PIVSD) carries a high mortality rate. We describe the successful management of a large VSD complicated by cardiogenic shock in a latecomer STEMI patient with complex coronary artery disease (CAD).

Background: Pyogenic flexor tenosynovitis (PFT) is a common and severe hand infection. Patients who present early can be treated with intravenous antibiotics.

Objectives: To determine whether PFT caused by animal bites and treated with antibiotics leads to a different outcome than other disease etiologies due to the extensive soft tissue insult and different bacterial flora.

Methods: We conducted a retrospective cohort study of 43 consecutive patients who presented with PFT between 2013 and 2020. The 10 patients who presented with PFT following an animal bite were compared to those who presented with PFT caused by any other etiology.

Results: Patients who were bitten pursued medical attention sooner: 1.9 ± 1.4 days compared with 5.3 ± 4.7 days (P = 0.001). Despite the quicker presentation, patients from the study group received similar antibiotic types and duration as controls. All patients were initially treated with intravenous antibiotics under surveillance of a hand surgeon. One patient (10%) from the study group and four controls (12%) were treated surgically (P = 1). Average follow-up was 17 ± 16 days. At the end of follow-up, one (10%) patient from the study group and three (9%) controls sustained mild range of motion limitation and one (3%) patient from the control group had moderate limitations (P = 0.855).

Conclusions: Intravenous antibiotic treatment, combined with an intensive hand surgeon follow-up, is a viable option for the treatment of PFT caused by animal bites.
