Background: Transanal minimally invasive surgery (TAMIS) is a single port access platform used for full thickness local excision of rectal lesions. It is an appealing alternative to a radical resection of rectum that often can cause a significant bowel dysfunction described as low anterior resection syndrome (LARS). LARS is evaluated using a validated score. Functional outcomes of patients undergoing TAMIS has not yet been evaluated using the LARS score.

Objectives: To evaluate long-term bowel function in patients who underwent TAMIS.

Methods: In this case series, all patients who underwent TAMIS in a single tertiary institute between 2011 and 2017 were retrospectively reviewed. We evaluated bowel function using the LARS score questionnaire through telephone interviews.

Results: The study consisted of 23 patients, average age of 67 ± 6.98 year; 72% were male. The median follow-up from the time of surgery was 5 years. Six patients (26.08%) had malignant type lesions. The average height of the lesion from the anal verge was 7.4 cm. The average size of the specimen was 4 cm. The total LARS score revealed that 17 patients (73.91%) had no definitive LAR syndrome following the surgery. Four patients (17.39%) fit the description of minor LARS and only two (8.69%) presented with major LARS.

Conclusions: TAMIS provides relatively good long-term functional outcomes in terms of bowel function. Further randomized studies with larger cohorts are still needed to better evaluate the outcomes.

Background: Stress hyperglycemia (SH) is a common finding in patients in pediatric emergency departments (PED) and has been related to increased morbidity and mortality.

Objectives: To assess the incidence of SH among children visiting the PED. To identify which diseases predispose patients to SH and whether they indicate a worse outcome.

Methods: Data were collected retrospectively from the medical records of all children aged 0–18 years who visited the PED during the years 2010–2014 and who had a glucose level of ≥ 150 mg/dl. Data collected included age, gender, weight, blood glucose level, presence or absence of a pre-existing or a new diagnosis of diabetes mellitus, and previous treatment with medications affecting blood glucose levels or with intravenous fluids containing dextrose. Data were collected regarding hospitalization, duration of hospitalization, discharge diagnosis, and survival status.

Results: The study population included 1245 children with SH, which comprised 2.6% of all patients whose blood glucose level was measured in the PED during the study period. The mean age of children with SH was 49 months; 709 (56.9%) were male. The mean blood glucose level was 184 mg/dl. The rate of hospitalization was 57.8%. The mean duration of hospital stay was 5.6 days and mortality rate was 0.96%. The majority were diagnosed with a respiratory illness.

Conclusions: SH is a common phenomenon among children evaluated in the PED and is associated with a high incidence of hospitalization. It may serve as an additional clinical indicator of disease severity.

Background: Following an intestinal anastomotic leak, stoma creation may be the safest approach. However, this method may be challenging and cause significant morbidity. In selected cases, a T drain approach can be beneficial and a stoma can be avoided.

Objectives: To present one group's experience with a T drain approach for anastomotic leaks.

Methods: Data on patients who underwent emergent re-laparotomy following gastrointestinal anastomotic leaks were retrieved retrospectively and assessed with a new intra-operative leak severity score.

Results: Of 1684 gastrointestinal surgeries performed from 2014 to 2018, 41 (2.4%) cases of anastomotic leaks were taken for re-laparotomy. Cases included different sites and etiologies. Twelve patients were treated with a T-tube drain inserted through the leak site, 18 had a stoma taken out, 6 re-anastomosis, 4 were treated with an Endosponge, and one primary repair with a proximal ileostomy was conducted. T drain approach was successful in 11 of 12 patients (92%) with full recovery. One patient did not improve and underwent reoperation with resection and re-anastomosis. A severity score of anastomotic integrity is provided to help surgeons in decision making.

Conclusions: A T drain approach can be an optimal solution in selected cases following an intestinal anastomotic leak. When the leak is limited, the remaining anastomosis is intact and the abdominal environment allows it, a T drain can be used and a stoma can be avoided.

Fibromyalgia is a common pain syndrome treated by physicians of many disciplines and presents with many co-morbidities. We reviewed the complexities in assessing disabilities in fibromyalgia patients and the complex interrelationships between patients, their working places, and  the medical community regarding preserving productivity. Flexibility is essential to keep the patients functional and productive. Job loss is costly to both society and patients and joint measures are needed to prevent unemployment.

In the absence of definitive anti-viral therapy, there is considerable interest in mitigating against severe inflammatory reactions in coronavirus disease-2019 (COVID-19) pneumonia to improve survival. These reactions are sometimes termed cytokine storm. PDE4 inhibitors (PDE4i) have anti-inflammatory properties with approved indications in inflammatory skin and joint diseases as well as chronic obstructive pulmonary disease (COPD). Furthermore, multiple animal models demonstrate strong anti-inflammatory effects of PDE4i in respiratory models of viral and bacterial infection and also after chemically mediated lung injury. The rationale for PDE4i use in COVID-19 patients comes from the multimodal mechanism of action with cytokine, chemokine, and other key pathway inhibition all achieved with an excellent safety profile. We highlight how PDE4i could be an overlooked treatment from the rheumatologic and respiratory armamentarium, which has potential beneficial immune-modulation for treating severe COVID-19 pneumonia associated with cytokine storms. The proposed use of PDE4i is also supported by age-related immune changes in inflammation severity in PDE4i modifiable pathways in primate coronavirus disease. In conclusion, over-exuberant anti-viral immune responses in older patients with COVID-19 may pose a substantial risk to patient survival and mitigation against such hyper-inflammation with PDE4i, especially with anti-viral agents, is a strategy that need to be pursed, especially in older patients

Background: Cyclophosphamide treatment has been associated with ovarian function impairment. Co-treatment with gonadotropin-releasing hormone-analogue (GnRH-a) seems to be able to prevent this complication. However, even though data are available on neoplastic patients, limited data have been published on systemic lupus erythematosus (SLE) women cohorts

Objectives: To evaluate GnRH-a efficacy on ovarian function preservation in SLE women receiving cyclophosphamide treatment

Methods: The authors performed a retrospective study including SLE women requiring cyclophosphamide treatment and compared those treated with and without GnRH-a (case and controls, respectively). All patients were evaluated before cyclophosphamide treatment and every 3 months in the following years. Ovarian function was evaluated using hormonal profiles

Results: The study comprised 33 SLE cyclophosphamide-treated women: 18 co-treated with triptorelin and 15 controls. The mean follow-up was 8.1 ± 5.1 years (range 4–11). Premature ovarian failure (POF) prevalence was significantly lower in SLE women treated by cyclophosphamide plus triptorelin compared to controls (11.1% vs. 33.3%, P = 0.0002). The occurrence of POF was significantly associated with higher age at the time of cyclophosphamide treatment (P = 0.008). Only patients in the GnRH-a treated group had successful pregnancies

Conclusions: The study provides information about the efficacy of co-treatment with GnRH-a in SLE women receiving cyclophosphamide, as demonstrated by the lower POF incidence compared to untreated subjects, based on long-term follow-up. These results reinforce the use of GnRH-a for fertility preservation in premenopausal SLE patients treated by cyclophosphamide

Background: Cardiovascular disease (CVD) is more frequent in patients with systemic lupus erythematosus (SLE) compared with age- and sex-matched healthy subjects. SLE is an autoimmune disease that is more prevalent in women (9:1). Women tend to develop CVD in post-menopausal years; however, women with SLE may develop endothelial dysfunction and CVD at a younger age in the pre-menopausal years.

Objectives: To study the endothelial function of adult-onset SLE patients from the north of Israel (the Galilee region) and to determine whether modern management (including biological treatments) changes the risk of developing CVD.

Methods: Thirteen females with adult-onset SLE without renal involvement were recruited to this prospective study. Clinical parameters (age, height, body mass index [BMI]), laboratory parameters (C-reactive protein [CRP] and hemoglobin level), and vascular responsiveness (flow mediated diameter percent change [FMD%]) were evaluated and compared to 11 age-matched healthy females. Student's t-test was used to find differences between the two groups.

Results: No difference was observed in adult-onset SLE female patients and their age- and sex-matched controls with regard to age (42.1 ± 11.8 years vs. 36.6 ± 10.8 years, P = NS), BMI (25 ± 1.8 kg/m² vs. 25 ± 2.5 kg/m², P = NS), and hemoglobin level (11.9 ± 0.9 gr% vs. 12.7 ± 1.2 gr%, P = NS). However, a significant difference was found in CRP (2.57 ± 2.2 mg vs. 0.60 ± 0.37 mg, P = 0.001), vascular responsiveness (0.94 ± 6.6 FMD% vs. 9.2 ± 8.1 FMD%, P = 0.012), and height (165.7 ± 4.5 cm vs. 171.6 ± 5.8 cm, P = 0.009).

Conclusions: Adult-onset SLE females had impaired endothelial function even though they were treated by modern protocols.

Background: Coronary artery bypass grafting (CABG) for primary reperfusion in patients with ST elevation myocardial infarction (STEMI) has largely been superseded byf primary percutaneous coronary intervention (PCI) and is estimated to be performed in ≤ 5% of STEMI cases.

Objectives: To compare early CABG (within 30 days following admission) and primary PCI outcomes following STEMI.

Methods: We analyzed a retrospective cohort of patients hospitalized with acute STEMI for early reperfusion therapy between January 2008 and June 2016. Short- and long-term outcomes were assessed for patients with STEMI undergoing primary PCI vs. early CABG as reperfusion therapy.

Results: The study comprised 1660 STEMI patients, 38 of whom (2.3%) underwent CABG within 30 days of presentation. Unadjusted 30-day mortality was more than twice as high in the CABG group (7.5%) than in the PCI group (3.3%); however, it did not reach statistical significance. Similar results were demonstrated for mortality rates beyond 30 days (22% vs. 14%, P = 0.463). All patients undergoing CABG beyond 72 hours following admission survived past 2 years. Multivariate analysis found no differences between the two groups in long-term mortality risk. propensity score matched long-term mortality comparison (30 days–2 years) yielded a 22% mortality rate in the CABG groups compared with 14% in the PCI group (P < 0.293).

Conclusion: Early CABG was performed in only a minority of STEMI patients. This high-risk patient population demonstrated worse outcomes compared to patients undergoing PCI. Performing surgery beyond 72 hours following admission may be associated with lower risk.

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: Abdominal tumors invading the inferior vena cava (IVC) present significant challenges to surgeons and oncologists.

Objectives: To describe a surgical approach and patient outcomes.

Methods: The authors conducted a retrospective analysis of surgically resected tumors with IVC involvement by direct tumor encasement or intravascular tumor growth. Patients were classified according to level of IVC involvement, presence of intravascular tumor thrombus, and presence of hepatic parenchymal involvement.

Results: Study patients presented with leiomyosarcomas (n=5), renal cell carcinoma (n=7), hepatocellular carcinoma (n=1), cholangiocarcinoma (n=2), Wilms tumor (n=1), neuroblastoma (n=1), endometrial leiomyomatosis (n=1), adrenocortical carcinoma (n=1), and paraganglioma (n=1). The surgeries were conducted between 2010 and 2019. Extension of tumor thrombus above the hepatic veins required a venovenous bypass (n=3) or a full cardiac bypass (n=1). Hepatic parenchymal involvement required total hepatic vascular isolation with in situ hepatic perfusion and cooling (n=3). Circular resection of IVC was performed in five cases. Six patients had early postoperative complications, and the 90-day mortality rate was 10%. Twelve patients were alive, and six were disease-free after a mean follow-up of 1.6 years.

Conclusions: Surgical resection of abdominal tumors with IVC involvement can be performed in selected patients with acceptable morbidity and mortality. Careful patient selection, and multidisciplinary involvement in preoperative planning are key for optimal outcome.

Background: Left ventricular assist devices (LVADs) are used more commonly in patients with advanced-stage heart failure. Some of these patients may require elective or urgent abdominal surgical procedures.

Objectives: To determine the outcomes of the management of LVAD-supported patients who underwent elective and urgent abdominal surgical procedures in our institution.

Methods: A retrospective review was conducted on 93 patients who underwent LVAD implantation between August 2008 and January 2017. All abdominal surgeries in these patients were studied, and their impact on postoperative morbidity and mortality was evaluated.

Results: Ten patients underwent abdominal surgical procedures. Of these procedures, five were emergent and five were elective. The elective cases included one bariatric surgery for morbid obesity, one hiatal hernia repair, two cholecystectomies, and one small bowel resection for a carcinoid tumor. The emergency cases included suspected ischemic colitis, right colectomy for bleeding adenocarcinoma, laparotomy due to intraabdominal bleeding, open cholecystectomy for gangrenous cholecystitis, and laparotomy for sternal and abdominal wall infection. All patients undergoing elective procedures survived. Of the five patients who underwent emergency surgery, three died (60%, P = 0.16) and one presented with major morbidity. One of the two survivors required reintervention. In total, 12 interventions were performed on this group of patients.

Conclusions: It is safe to perform elective abdominal procedures for LVAD-supported patients. The prognosis of these patients undergoing emergency surgery is poor and has high mortality and morbidity rates.
