Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, distinct pulmonary vascular disease, which is caused by chronic obstruction of major pulmonary arteries. CTEPH can be cured by pulmonary endarterectomy (PEA). PEA for CTEPH is a challenging procedure, and patient selection and the perioperative management are complex, requiring significant experience.

Objectives: To describe the establishment of a national CTEPH–PEA center in Israel and present results of surgery.

Methods: In this study, we reviewed the outcomes of PEA in a national referral, multi-disciplinary center for CTEPH–PEA. The center was established by collaborating with a high-volume center in Europe. A multidisciplinary team from our hospital (pulmonary hypertension specialist, cardiac surgeon, cardiac anesthesiologist and cardiac surgery intensivist was trained under the guidance of an experienced team from the European center.

Results: A total of 38 PEA procedures were performed between 2008 and 2018. We included 28 cases in this analysis for which long-term follow-up data were available. There were two hospital deaths (7%). At follow-up, median New York Heart Association (NYHA) class improved from III to I (P < 0.0001), median systolic pulmonary pressure decreased from 64 mmHg to 26 mmHg (P < 0.0001), and significant improvements were seen in right ventricular function and exercise capacity.

Conclusions: A national center for performance of a rare and complex surgical procedure can be successfully established by collaboration with a high-volume center and by training a dedicated multidisciplinary team.

Rheumatic diseases commonly affect women of childbearing age, when women may be contemplating pregnancy or they discover an unplanned pregnancy. Therefore, specific issues about pregnancy planning and management are commonly encountered in patients during these times. Knowledge of the effect of pregnancy on disease activity is important for counseling. This review summarizes recent data on the course of different rheumatic diseases during pregnancy and the postpartum period. Rheumatoid arthritis and systemic lupus erythematosus are the most commonly investigated diseases. Data are increasing about spondyloarthritis. Sparse data are available for other rheumatic diseases. Despite the differences in these diseases and the various courses these disease take during pregnancy, a common feature is that active maternal disease in the months prior to conception increases the risk of flares during pregnancy, which in turn can lead to adverse pregnancy outcomes. Therefore, maternal and fetal health can be optimized if conception is planned when disease is inactive so that a treatment regimen can be maintained throughout pregnancy.

Uveitis is an inflammatory disorder of the uveal tract of the eye that can affect both adults and children. Non-infectious uveitis can be an expression of a systemic autoimmune condition, or it can be idiopathic. It is a serious disease, associated with possible severe complications leading to visual impairment and blindness. For this reason, a prompt diagnosis and assessment of an appropriate treatment, with the collaboration of specialists such as ophthalmologists and rheumatologists, are extremely important. Many treatment options may be associated to side effects; therefore, clinicians should follow a stepladder approach starting with the least aggressive treatments to induce remission of inflammation. In this review, we reported the current evidence-based treatments for non-infectious uveitis in pediatric and adult patients with particular attention to the biologic response modifier treatment options. Important multicenter studies have demonstrated the efficacy of adalimumab, both in adults (VISUAL I, VISUAL II, VISUAL III) and in children (SYCAMORE, ADJUVITE), while for other agents data are still scarce.

Background: Malignancy is a known risk factor for venous thromboembolism; however, the association with arterial thromboembolic events remains unclear.

Objectives: To examine the association between non-ST-elevation myocardial infarction (NSTEMI) and non-significant coronary artery disease (CAD) and the presence of new or occult malignancy.

Methods: An observational cohort, single-center study was performed 2010–2015. Adult patients with NSTEMI, who underwent coronary angiography and had no significant coronary lesion, were included. Using propensity score matching, we created a 2:1 matched control group of adults with NSTEMI, and significant coronary artery disease. Risk factors for new or occult malignancy were assessed using multivariate backward stepwise logistic regression analysis. The primary outcome was new or occult malignancy, defined as any malignancy diagnosed in the 3 months prior and 6 months following the myocardial infarction (MI).

Results: During the study period, 174 patients who presented with MI with non-obstructive coronary arteries were identified. The matched control group included 348 patients. There was no significant difference in the group demographics, past medical history, or clinical presentation. The incidence of new or occult malignancy in the study group was significantly higher (7/174, 4% vs. 3/348, 0.9%, P = 0.019). NSTEMI with non-significant CAD was an independent risk factor for occult malignancy (odds ratio [OR] 4.6, 95% confidence interval [95%CI] 1.1–18.7). Other risk factors included active smoking (OR 11.2, 95%CI 2.5–49.1) and age (OR 1.1, 95%CI 1.03–1.17).

Conclusions: NSTEMI with non-significant CAD may be a presenting or early marker of malignancy and warrants further investigation.

Background: Recently, studies have found that non-alcholic fatty liver disease (NAFLD) is associated with bacterial infections. Attempts to identify risk factors for recurrent urinary tract infections (rUTIs) are still underway.

Objectives: To examine a possible association between NAFLD and rUTIs among premenopausal women.

Methods: In a case-control study, 1009 hospitalized premenopausal women with a UTI during a period of 3 years were retrospectively studied. A total of 186 subjects with rUTIs and 186 controls without a history of rUTIs were included in this study. Each participant had an abdominal ultrasonogram as part of the inclusion criteria. The two groups were compared in terms of risk factors for rUTIs, such as maternal history of rUTIs, use of contraceptives, frequency of sexual intercourse, metabolic syndrome, obesity, use of probiotics, serum levels of vitamin D, and NAFLD. An rUTI was defined as three or more episodes of UTI over a period of 1 year. NAFLD was diagnosed based on abdominal ultrasonography examination.

Results: Mean age of the 372 participants was 39.7 ± 5 years. NAFLD was diagnosed in 81/186 subjects (43.5%) with rUTIs vs. 40/186 controls (21.5%), P = 0.05. Women with rUTIs were more often obese and presented with lower serum levels of vitamin D than controls. Multivariate analysis showed that NAFLD (odds ratio = 1.6, 95% confidence interval 1.3–2.0, P = 0.04) were associated with rUTIs in premenopausal women.

Conclusions: NAFLD was associated with rUTI in premenopausal women, independent of metabolic syndrome. Further studies are needed to confirm this association.

Background: Pulmonary rehabilitation has shown significant benefit for patients with chronic obstructive pulmonary disease (COPD). The effect on non-COPD pulmonary patients is less well established.

Objectives: To determine whether pulmonary rehabilitation is also beneficial for non-COPD pulmonary patients.

Methods: Clinical and demographic data on non-COPD pulmonary patients who participated in our institutional pulmonary rehabilitation program between January 2009 and December 2016 were collected. Participants engaged in a 60-minute, twice-weekly, ambulatory hospital-based program lasting 12 to 24 sessions. Sessions included both endurance and muscle training as well as healthy lifestyle educational activities. The six-minute walk test (6MWT) and the St. George's Respiratory Questionnaire (SGRQ) were conducted before and after the rehabilitation program.

Result: We recruited 214 non-COPD patients, of whom 153 completed at least 12 sessions. Of these, 59 presented with interstitial lung disease (ILD), 18 with non-ILD restrictive lung defects, 25 with asthma, 30 with lung cancer, and 21 with other conditions (e.g., pulmonary hypertension, bronchiectasis) The groups demonstrated significant improvement in 6MWT and in SGRQ scores. Non-COPD patients gained a 61.9 meter (19%) improvement in the 6MWT (P < 0.0001) and 8.3 point reduction in their SGRQ score (P < 0.0001).

Conclusions: Pulmonary rehabilitation is effective in non-COPD pulmonary patients. As such, it should be an integral part of the treatment armament provided to the vast majority of those suffering from chronic respiratory disease.

Throughout history, studies on episodes of famine have led to the discovery of metabolic abnormalities and hormonal aberrations as well as an increased incidence of cancer and mental health conditions. Starvation during early life is thought to nfluence the programming of childhood and adult bone metabolism, which may result in poor bone health in later life. This observational case series includes a small group (with no control group) of famine-exposed Holocaust survivors and their descendants. We proposed an investigational mechanism to determine any association between starvation and osteoporosis, both in the individual survivors and in their descendants.

Background: Reports of longevity in Holocaust survivors (HS) conflict with excess prevalence of chronic diseases described among them. However, data on their long-term risk of cardiovascular diseases (CVD) are limited. Clinical data on large representative groups of HS who were exposed to severe persecution are also limited.

Objectives: To determine the prevalence of CVD and the risk factors in a large cohort of elderly HS compared to elderly individuals who were not exposed to the Holocaust (NHS).

Methods: CVD prevalence rates and risk factors data from the computerized system of the central district of Clalit Health Services, the largest Israeli health maintenance organization (HMO) in Israel were evaluated in a retrospective observational study. The study was comprised of 4004 elderly HS who underwent direct severe persecution. They were randomly matched by identification numbers to 4004 elderly NHS.

Results: HS were older than NHS and 51% of them were older than 85 years. The prevalence rate of ischemic heart disease (IHD) was significantly higher among HS. HS underwent significantly more cardiac interventions (20% vs. 15.7%, P < 0.05). HS status was an independent risk factor for increased IHD and for more coronary interventions.

Conclusions: Despite having a higher prevalence of CVD, a substantial number of HS live long lives. This finding may imply both unique resilience and ability to cope with chronic illness of the survivors as well as adjusted medical services for this population. These findings may help in planning the treatment of other mass trauma survivors.

Background: Multidisciplinary biopsychosocial rehabilitation for patients presenting with rheumatic diseases has been shown to produce better results in a warm climate. Dead Sea Climatotherapy (DSC) has been successfully used for decades to treat many patients with rheumatic diseases.

Objectives: To evaluate the short-term improvement of Norwegian patients who presented with chronic pain following a multidisciplinary biopsychosocial approach to treatment combined with DSC. Both objective and subjective clinical parameters were evaluated.

Methods: This retrospective study included a statistical analysis of 938 patients presenting with rheumatoid arthritis and ankylosing spondylitis (n=105), osteoarthritis (n=342), fibromyalgia (n=374), and other orthopedic conditions (n=117). Clinical assessments were conducted before and after a 3 week treatment program at the Dead Sea.

Results: Six parameters improved significantly in the rheumatoid arthritis and ankylosing spondylitis group as well as in the osteoarthritis group. Five parameters in the fibromyalgia group improved, while two improved in the orthopedic conditions group. Overall, major significant changes occurred in the pain self-assessment, joint motility, and daily activities scores.

Conclusions: A 3-week multidisciplinary biopsychosocial program combined with DSC induced positive changes in the clinical parameters of Norwegian patients presenting with chronic musculoskeletal pain.
