Background: Cardiac rehabilitation (CR) is underutilized globally despite evidence of clinical benefit. Major obstacles for wider adoption include distance from the rehabilitation center, travel time, and interference with daily routine. Tele-cardiac rehabilitation (tele-CR) can potentially address some of these limitations, enabling patients to exercise in their home environment or community.

Objectives: To evaluate the clinical and physiological outcomes as well as adherence to tele-CR in patients with low cardiovascular risk and to assess exercise capacity, determined by an exercise stress test, using a treadmill before and following the 6-month intervention.

Methods: A total of 22 patients with established coronary artery disease participated in a 6-month tele-CR program. Datos Health (Ramat Gan, Israel), a digital health application and care-team dashboard, was used for remote monitoring, communication, and management of the patients.

Results: Following the 6-month tele-CR intervention, there was significant improvement in exercise capacity, assessed by estimated metabolic equivalents with an increase from 10.6 ± 0.5 to 12.3 ± 0.5 (P = 0.002). High-density lipoproteins levels significantly improved, whereas low-density lipoproteins, triglyceride, glycosylated hemoglobin, and systolic and diastolic blood pressure levels were not significantly changed. Exercise adherence was consistent among patients, with more than 63% of patients participating in a moderate intensity exercise program for 150 minutes per week.

Conclusions: Patients who participated in tele-CR adhered to the exercise program and attained clinically significant functional improvement. Tele-CR is a viable option for populations that cannot, or elect not to, participate in center-based CR programs.

Background: During Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) the surgeon operates exclusively through a single vaginal entry point, leaving no external scarring.

Objectives: To evaluate the learning curve of vNOTES hysterectomy by experienced gynecologists based on surgical times and short-term outcomes.

Methods: A retrospective study was conducted of the first 25 vNOTES hysterectomy surgeries performed from July to December 2018 at Rambam Health Care Campus by a single surgeon. The primary outcome was hysterectomy time. Secondary outcomes included intra-operative bleeding, length of hospitalization, postoperative pain, and need for analgesia. Socio-demographic and clinical data were retrieved from patient electronic medical charts.

Results: Median age was 64.5 years (range 40–79). Median hysterectomy time was 38 minutes (range 30–49) from the first cut until completion. Comparisons between median hysterectomy time in the first 10 hysterectomies and in the 15 subsequent procedures demonstrated a significant decrease in median total time: 45 minutes (range 41–49) vs. 32 minutes (range 30–38), respectively (P = 0.024). The median estimated intraoperative blood loss decreased from 100 ml (range 70–200) in the first 10 hysterectomies to 40 ml (range 20–100) in the subsequent procedures (P = 0.011)

Conclusions: vNOTES hysterectomy is feasible by an experienced gynecologist, with an exponential improvement in surgical performance in a short period as expressed by the improvement in hysterectomy time, low complication rates, negligible blood loss, minimal post-surgical pain, fast recovery, and short hospitalization. vNOTES allows easier and safer access to adnexal removal compared to conventional vaginal surgery.

Background: Bowel ultrasound has several possible uses in inflammatory bowel disease (IBD), including the initial evaluation of suspected IBD, monitoring of therapeutic response, detection of relapse, and diagnosis of complications as well as of extra-intestinal manifestations. However, its use has been limited mainly to countries where it is performed by the attending physician. 

Objectives: To investigate the feasibility and sensitivity of bedside bowel ultrasound performed by a gastroenterologist for assessing disease activity and complications in IBD.

Methods: We performed a feasibility study to compare the results of bowel ultrasound examination with those of another cross-sectional imaging modality (computed tomographic enterography or magnetic resonance enterography) in Crohn's disease, or with colonoscopy in ulcerative colitis.

Results: Between May 2015 and March 2016, 178 bowel ultrasound examinations were performed in 178 patients with suspected or established diagnosis of IBD. In 79 cases the results of another cross-sectional imaging or endoscopic examination performed within 3 months prior to the ultrasound exam were available. The sensitivity for detection of intestinal bowel thickening (a surrogate of inflammation) was 90%, and for detection of Crohn's disease complications, namely bowel stenosis and inflammatory mass, was 94% and 75%, respectively.

Conclusions: Bowel ultrasound is a useful and feasible bedside imaging tool for the detection of inflammation and complications in IBD patients. Bedside bowel ultrasound can be a valuable non-invasive tool to assess disease activity and complications in IBD patients when performed by the attending physician.

 

Background: The prevalence of heart failure (HF) is increasing rapidly with high readmission rates, mainly due to fluid retention. Ultrafiltration (UF) is a mechanical method for removing fluids. Introduced only recently in Israel, the skill and experience required for outpatient congested HF patients are scarce.

Objectives: To evaluate the feasibility and safety of UF therapy in congested HF patients in outpatient clinics under a strict protocol of monitoring and therapy that we developed.

Methods: Between April and September 2013 we applied UF in our outpatient clinic to seven chronically congested HF patients with NYHA III-IV who did not respond adequately to diuretics. We administered a total of 38 courses.

Results: On average, 1982 ml fluid per course was removed without significant adverse events and with patients' subjective feeling of improvement. Only two courses were interrupted prematurely due to mechanical problems but were completed without harm to the patients.

Conclusions: Under appropriate professional medical supervision, UF therapy in an outpatient setting is a safe and effective procedure and serves as an additional tool for managing congested HF patients who do not respond adequately to diuretics.

Background: Gallium scintigraphy is frequently used in the evaluation of fever of unknown origin, although its utility has been addressed in only a few studies.

Objectives: To evaluate the utility of gallium scintigraphy in the evaluation of patients with FUO[1] in our department.

Methods: We reviewed the charts of all patients from our department who had undergone gallium scintigraphy during the years 1995–2002 for the evaluation of FUO and who met the criteria for the definition of FUO. Demographic, clinical and laboratory data in addition to the results of gallium scintigraphy were documented. The patients were divided into two groups: those with a normal gallium study (group 1) and those with an abnormal gallium study (group 2). The second group was further divided into two groups: those whose gallium study results contributed to the diagnosis of the cause of FUO (group 2A) and those whose gallium study results did not (group 2B).

Results: A total of 102 patients met the study criteria. The male: female ratio was 54:48 and the mean age ± SD was 62.4 ± 20 years. A final diagnosis had been reached in 63 patients (62%), among whom the etiology was infectious in 54%, neoplastic in 19% and immunologic/rheumatic in 16%. Forty-one patients (40% of all the patients) (Group 2) had an abnormal gallium scintigraphy, and in only 21 patients (21% of all the patients) (Group 2A) did the gallium study results contribute to the diagnosis of the cause of FUO. However, in only two patients from Group 2A (2% of all the patients in our study) was the contribution of gallium study considered significant or crucial to the diagnosis of the cause of FUO.

Conclusions: The utility of gallium scintigraphy in the evaluation of FUO is very limited.
