Novel Urinary Biomarkers and Chronic Kidney Disease After Coronary Angiography: A Prospective Case-Controlled Study

BACKGROUND: Novel urinary biomarkers may have potential for early detection of acute kidney injury. AIM: The aim of the study was to test two urinary biomarkers: Kidney injury molecule-1(KIM-1) and liver-type fatty acid binding protein (L-FABP) as markers of kidney injury following coronary angiography. METHODS: This is a prospective non-randomized controlled trial, performed in two large teaching hospitals. Patients were recruited from the catheter lab or form nephrology outpatient clinics. In group (A), 100 patients with AKI on top of CKD after coronary angiography and Group B: Thirty-one patients with stable CKD as a control. KIM-1 and L-FABP were measured at base line and after 3 months. RESULTS: In group (A), 100 patients who had acute on top of CKD after coronary angiography, stage progression occurred in 15 patients in group (A) compared to two patients in group (B) (p = 0.28). The median change in eGFR after 3 months was not statistically significant between both groups (p = 0.8). Median baseline urinary liver-type fatty acid binding protein was higher in Group A compared to Group B (3.7 μg/g vs. 1.82μg/g). The change in L-FABP from baseline to 3 months was significant between both groups (p < 0.001). The median urinary concentrations of KIM-1 and L-FABP were higher at the end of the follow-up compared to base line values in both groups, (p < 0.000). CONCLUSION: Urinary L-FABP correlates with kidney function decline in patients with acute on top of CKD after coronary angiography. Urinary levels of KIM-1 and L-FABP at 3 months increase significantly compared to baseline in patients with progressive CKD

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

Steroid resistant focal segmental glomerulosclerosis: effect of arterial hyalinosis on outcome: single center study

Background. Few data with adequate evidence exists as regards the effect of Cyclosporine (CsA) and mycophenolate mofetil (MMF) on pathological prognostic parameters in patients with steroid resistant focal segmental glomerulosclerosis (FSGS). The purpose of the present study is to compare the effect of cyclosporin and mycophenolate mofetil in addition to steroids on functional and histopathologic renal parameters in patients with steroid resistant FSGS one year after treatment

Laparoscopic re-implantation of refluxing ureter in children: A feasibility study

Objective: To report our initial experience in the application of laparoscopy in the management of children with unilateral vesico-ureteric reflux (VUR) using the laparoscopic extravesical transperitoneal approach following the Lich–Gregoir technique, and to evaluate the results and benefits of this technique for such patients. Patients and methods: Between February 2013 and August 2014, 17 children [13 girls and four boys, with a median (range) age of 60 (24–120) months] presented with recurrent febrile urinary tract infections and were diagnosed with unilateral VUR. They underwent transperitoneal extravesical laparoscopic ureteric re-implantation following the Lich–Gregoir technique. Postoperatively abdomino-pelvic ultrasonography was done at 1 month after surgery and voiding cystourethrography (VCUG) at 3 months after surgery, and in cases with persistent VUR or de novo contralateral VUR another VCUG was done at 6 months after surgery. Results: The median (range) operative time was 90 (80–120) min and the postoperative hospital stay was 2 (2–5) days. Intraoperative and postoperative complications were minimal. Patients were followed-up for a median (range) of 6 (3–21) months. All the children had complete resolution symptomatically and on VCUG, without further intervention. Conclusions: The laparoscopic extravesical transperitoneal approach for ureteric re-implantation, following the Lich–Gregoir technique, is feasible and very effective in the management of VUR. Prospective randomised studies are eagerly awaited to define the benefits of this technique to patients, as well as to determine the cost-effectiveness of this approach

Linear growth in relation to the circulating concentration of insulin-like growth factor-I in young children with acyanotic congenital heart disease with left to right shunts before versus after surgical intervention

Objectives: The aim was to determine the degree of linear growth retardation of patients with congenital acyanotic heart disease at presentation and the magnitude of catch-up growth, if any, in relation to their echocardiographic changes and insulin-like growth factor- I (IGF-I) concentration before versus after surgical intervention. Materials and Methods: This prospective study recorded the anthropometric data and measured the circulating IGF-I, free thyroxin (FT4), and thyrotropin (TSH) of 27 infants and children with congenital acyanotic heart disease with left to right shunt (10 with VSD, 8 with ASD, 9 PDA) without heart failure, or severe pulmonary hypertension, before and 12 months or more after surgical or catheter intervention. Eighty normal age and sex- matched normal siblings of these patients were included as controls for the auxologic data. Results: At presentation, patients′ mean age = 35.6 ± 26 months, height SDS (HtSDS) = -1.6 ± 1.1, and body mass index (BMI) = 15.1 ± 2.5. They were significantly shorter and with lower BMI compared to normal controls (HtSDS = 0.25 ± 0.3, BMI = 16.4 ± 1.5). One year or more after catheter or surgical treatment, the HtSDS and BMI increased significantly in patients to -0.55 ± 0.9 and 15.9 ± 1.5, respectively). IGF-I levels increased from 46.8 ± 29 mcg/L before to 77.3 ± 47.6 mcg/L after intervention. No significant change has been detected in circulating FT4 or TSH concentrations. The HtSDS after treatment was correlated with the IGF-I concentration (r = 0.804, P < 0.001). The change in the HtSDS after intervention was correlated significantly with BMI (r = 0.594, P 0.001) and negatively with age (r = -0.52, P< 0.01). The shunt size was correlated negatively with BMI and HtSDS before intervention (r = -0.35, P < 0.01 and 0.01 and r = -0.461, P < 0.05, respectively). GVSDS after intervention surgery was correlated with BMI after intervention (r = 0.495, P < 0.001) and negatively with the age at operation (r = -0.683, P < 0.001). Conclusions: In congenital acyanotic heart diseases, early surgical interference and weight gain have beneficial effect on postoperative growth spurt. This catch-up growth appears to be mediated through activation of the GH/IGF-I system and suggests an important role of increasing BMI (an indicator of nutrition) as an imperative factor

Pentoxifylline Effects on Hospitalized COVID-19 Patients with Cytokine Storm Syndrome: A Randomized Clinical Trial

COVID-19 is a fatal, fast-spreading pandemic, and numerous attempts are being made around the world to understand and manage the disease. COVID-19 patients may develop a cytokine-release syndrome, which causes serious respiratory diseases and, in many cases, death. The study examined the feasibility of employing legally available anti-inflammatory pentoxifylline (PTX), a low toxicity and cost medication, to mitigate the hyper-inflammation caused by COVID-19. Thirty adult patients who tested positive for SARS-CoV2 were hospitalized owing to the cytokine storm syndrome. They were given 400 mg of pentoxifylline orally TID according to the standard COVID-19 protocol of the Egyptian Ministry of Health. Besides this, a group of thirty-eight hospitalized COVID-19 patients who received the standard COVID-19 protocol was included in the study as a control group. The outcomes included laboratory test parameters, clinical improvements, and number of deaths in both groups. After receiving PTX, all patients showed a significant improvement in C reactive protein (CRP), and interleukin-6 (IL-6) levels at p p = 0.004, respectively, while there was an increase in total leukocyte count (TLC) and neutrophil-to-leucocyte ratio (NLR) at p p < 0.01, while showing no statistically significant difference in the control group. The median initial ALT (42 U/L) in the treatment group showed a decrease compared to the control group (51 U/L). No statistical significance was reported regarding clinical improvement, length of stay, and death percentages between the two groups. Our results showed no significant improvement of PTX over controls in clinical outcomes of hospitalized COVID-19 patients. Nevertheless, PTX displayed a positive effect on certain inflammatory biomarkers
