Background: Morbidities related to obesity are usually associated with its severity and duration. Yet, the onset of serious morbidities in early adulthood among otherwise healthy adolescents with obesity is understudied. We aimed to investigate the association between adolescent BMI and serious morbidities before age 25 years.

Background: Underdiagnosis of relevant risk factors has contributed to the increasing stroke incidence in young adults. Blood pressure cut-off values for adolescents are neither sex specific nor based on cardiovascular outcomes.

Methods: This nationwide, population-based, retrospective cohort study included all Israeli adolescents 16-19 years of age who were medically evaluated before compulsory military service from 1985 to 2013, including routine blood pressure measurements.

Posttraumatic stress disorder (PTSD) often occurs following mass casualty events, yet the connection between the number of individuals injured in an event and PTSD risk in smaller-scale events (i.e., involving one or several injured persons) remains unclear.

Purpose: Prompt vascular access is crucial for resuscitating bleeding trauma casualties in prehospital settings but achieving peripheral intravenous (PIV) access can be challenging during hemorrhagic shock due to peripheral vessel collapse. Early intraosseous (IO) device use is suggested as an alternative. This study examines injury characteristics and factors linked to IO access requirements.

Article Synopsis
  • The study aimed to evaluate the risk of seizures in patients with Giant Cell Arteritis (GCA) compared to matched controls in Israel.
  • A total of 8,103 GCA patients and 32,412 controls were analyzed, showing that GCA patients had a higher incidence of seizures (15.92 cases per 10,000 person-years) than controls (9.62 per 10,000).
  • The findings indicate that GCA patients have a significantly increased risk of seizures, which is likely related to the inflammatory state associated with GCA, rather than pre-existing conditions like stroke.

Background: Stroke is increasingly prevalent at younger ages but the risk factors are uncertain. We examined the association between adolescent cognitive function and early-onset stroke.

Methods: This was a nationwide population-based cohort study of 1 741 345 Israeli adolescents (42% women) who underwent comprehensive cognitive function tests at age 16-20 years, before mandatory military service, during 1987-2012.

: Trauma laparotomy (TL) remains a cornerstone of trauma care. We aimed to investigate prehospital measures associated with in-hospital mortality among casualties subsequently undergoing TLs in civilian hospitals. : This retrospective cohort study cross-referenced the prehospital and hospitalization data of casualties treated by Israel Defense Forces-Medical Corps teams who later underwent TLs in civilian hospitals between 1997 and 2020.

Background: Pelvic fractures resulting from high-energy trauma can frequently present with life-threatening hemodynamic instability that is associated with high mortality rates. The role of pelvic exsanguination in causing hemorrhagic shock is unclear, as associated injuries frequently accompany pelvic fractures. This study aims to compare the incidence of hemorrhagic shock and in-hospital outcomes in patients with isolated and non-isolated pelvic fractures.

Study Objectives: Fibromyalgia (FM) is one of the most common causes of chronic widespread musculoskeletal pain, but also sleep disturbances, cognitive and psychological disorders. It has been suggested that FM may have a correlation with cardiovascular events. In this study, we aimed to assess the association between FM and ischemic heart disease (IHD).

Introduction: Silicone breast implants (SBI) result in immune dysregulation and are associated with autoimmune diseases. Recently, we reported dysregulated levels of IgG autoantibodies directed against G protein-coupled receptors (GPCRs) of the autonomic nervous system which were linked to the autoimmune dysautonomia in silicone breast implant illness (SBII).

Aims: We aimed to explore the possible association between allergy with dysregulated IgE autoantibodies directed against GPCRs of the autonomic nervous system in women with SBI.

Article Synopsis
  • The study investigates the impact of adolescent body mass index (BMI) on the development of early chronic kidney disease (CKD) in young adulthood.
  • Data was collected from a large cohort of Israeli adolescents evaluated for military service and linked to a CKD registry, excluding those with existing kidney issues or missing data.
  • Findings show that higher BMI in adolescence correlates with an increased risk of early CKD, particularly in males, suggesting obesity may be a significant risk factor for kidney health later in life.

Background: Posttraumatic stress disorder (PTSD) is prevalent among military personnel and may arise following a wide range of traumatic exposures. Consciousness level following traumatic injury may play a role in the development of PTSD, but its effects have been primarily investigated in the context of traumatic brain injury.

Methods: Registry-based study surveying three databases documenting care from point of injury to long-term rehabilitation of traumatic injuries among military personnel.

Background: The association between body mass index (BMI) and migraine in adults has been well established. However, studies in children and adolescents are inconclusive. We aimed to study the association between BMI and migraine using a national dataset that comprises the electronic medical records of more than two million adolescents.

We explored a possible association between palpitation manifestation in women with silicone breast implants (SBIs) with circulating level of autoantibodies directed against autonomic nervous system (ANS) receptors. The study was conducted in 93 women with SBIs who arrived to our clinic with diverse symptoms thought to be associated with their implants. Titers of 11 various autoantibodies were measured in the sera of women with SBIs who experienced palpitations (Palpitations, n = 47), did not experience palpitations (Non, n = 46), and healthy women (Control, n = 36).

Background: Low serum magnesium (sMg) is associated with cardiovascular risk factors and atherosclerotic disease.

Objective: To evaluate the association between sMg levels on admission and clinical outcomes in hospitalized non-ST-elevation myocardial infarction (NSTEMI) patients.

Methods: A retrospective analysis of all patients admitted to a single tertiary center with a primary diagnosis of NSTEMI.

Article Synopsis
  • * Researchers analyzed data from over 1.6 million adolescents and found that those with HSD/hEDS had a significantly higher prevalence of IBS (1.5%) compared to the control group (0.5%).
  • * The results highlight a strong association between HSD/hEDS and IBS, suggesting that increased clinical awareness could lead to better diagnosis and treatment, while also calling for further research into the underlying connections between these disorders.

Behind armor blunt trauma (BABT) is a non-penetrating injury caused by energy transfer and rapid deformation of protective body armor. Although modern military body armor is designed to prevent penetrating trunk injuries, high-energy projectiles can produce a significant energy transfer to tissues behind the armor and inflict injuries such as fractures or organ contusions. However, knowledge of BABT is limited to biomechanical and cadaver modeling studies and rare case reports.

Background: Previous studies demonstrated unclear and vast variability in the association between Ankylosing Spondylitis (AS) and the risk of cancer.

Objectives: To assess the risk of overall and site-specific malignancies for AS patients in Israel, while examining the role of comorbidities and immunomodulatory therapy.

Methods: We conducted a retrospective electronic data-based study including all AS patients diagnosed between 2002 and 2018, with no history of cancer prior to enrollment, with 5:1 ratio matched-control by age, gender, and place of residence.

The association between the clinical picture of symptomatic women with silicone breast implants (SBI) and dysregulated immunity was in dispute for decades. In the current study, we describe for the first time the functional activity of purified IgG antibodies derived from symptomatic women with SBIs (suffering from subjective/autonomic-related symptoms), both in vitro and in vivo. We found that IgGs, derived from symptomatic women with SBIs, dysregulate inflammatory cytokines (TNFα, IL-6) in activated human peripheral blood mononuclear cells, compared to healthy-women-derived IgGs.
