Abstract
Purpose: The SARS-CoV-2 pandemic was declared a global public health emergency. Determinants of mortality in the general population are now clear, but specific data on patients with breast cancer (BC) remain limited, particularly in developing nations. Materials and methods: We conducted a longitudinal, multicenter cohort study in patients with BC and confirmed SARS-CoV-2 infection. The primary end point was the proportion of patients on treatment for severe SARS-CoV-2 infection (defined as need for hospitalization) or early death (within 30 days of diagnosis). Data were evaluated sequentially in the following way: i) univariate Fisher’s exact test; ii) multivariable logistic regression analysis; and iii) multivariable logistic regression. In items i and ii only those with P< 0.1 are considered significant and in stage iii only those with p< 0.05 were the final significant variables. We divided patients’ data into three major variable domains: a) signs and symptoms; b) comorbidities; and c) tumor and treatment characteristics; in item ii each variable domain was tested separately, finally, in item iii the significant variables of all domains were tested together and we called it the integrative step. Results: From April 2020 to June 2021, 413 patients with BC and COVID-19 were retrospectively registered, of which 288 (70%) had an identified molecular subtype and 273 (66%) had stage information. Most patients were on active systemic therapy or radiotherapy (73.2%), most of them in the curative setting (69.5%). The overall rate of severe SARS-CoV-2 was 19.7% (95% CI, 15.3-25.1). In the integrative multivariate analysis, factors associated with severe infection were metastatic setting, chronic pain, acute dyspnea, and cardiovascular comorbidities. Recursive partitioning modeling used acute dyspnea, metastatic setting, and cardiovascular comorbidities to predict non-progression to severe infection, yielding a negative predictive value of 84.9% (95% CI, 78.9%-88.3%). Conclusion: The rate of severe COVID-19 in patients with BC is influenced by prognostic factors that partially overlap with those reported in the general population. High-risk patients should be considered candidates to active preventive measures to reduce the risk of infection, close monitoring in the case of exposure or SARS-CoV-2 -related symptoms and prophylactic treatment once infected.

Abstract
PURPOSE The COVID-19 pandemic remains a public health emergency of global concern. Determinants of mortality in the general population are now clear, but specific data on patients with cancer remain limited, particularly in Latin America. MATERIALS AND METHODS A longitudinal multicenter cohort study of patients with cancer and confirmed COVID-19 from Oncoclínicas community oncology practice in Brazil was conducted. The primary end point was all-cause mortality after isolation of the SARS-CoV-2 by Real-Time Polymerase Chain Reaction (RT-PCR) in patients initially diagnosed in an outpatient environment. We performed univariate and multivariable logistic regression analysis and recursive partitioning modeling to define the baseline clinical determinants of death in the overall population. RESULTS From March 29 to July 4, 2020, 198 patients with COVID-19 were prospectively registered in the database, of which 167 (84%) had solid tumors and 31 (16%) had hematologic malignancies. Most patients were on active systemic therapy or radiotherapy (77%), largely for advanced or metastatic disease (64%). The overall mortality rate was 16.7% (95% CI, 11.9 to 22.7). In univariate models, factors associated with death after COVID-19 diagnosis were age ≥ 60 years, current or former smoking, coexisting comorbidities, respiratory tract cancer, and management in a noncurative setting (P < .05). In multivariable logistic regression and recursive partitioning modeling, only age, smoking history, and noncurative disease setting remained significant determinants of mortality, ranging from 1% in cancer survivors under surveillance or (neo)adjuvant therapy to 60% in elderly smokers with advanced or metastatic disease. CONCLUSION Mortality after COVID-19 in patients with cancer is influenced by prognostic factors that also affect outcomes of the general population. Fragile patients and smokers are entitled to active preventive measures to reduce the risk of SARS-CoV-2 infection and close monitoring in the case of exposure or COVID-19-related symptoms.

Abstract
AIM According to National Kidney Foundation guidelines, early stages of chronic kidney disease (CKD) can be detected through the estimated glomerular filtration rate (eGFR). We assessed complications following colorectal surgery (CRS) in patients with CKD Stages 3 and 4, as defined by the eGFR. METHOD Patients with CKD were identified within our database. Patients with an eGFR of 15-59 ml/min (CKD Stages 3 and 4) formed the CKD group and were compared with American Society of Anesthesiology (ASA) score-matched controls with an eGFR of ≥ 60 ml/min. Assessments included demographics, comorbidity, ASA score, operative details and 30-day postoperative outcome. RESULTS Seventy patients in the CKD group were matched with 70 controls. ASA scores and length of stay did not differ significantly between the groups. CKD patients were older (mean age 76.5 years vs 71.1 years; P < 0.001) and had a lower mean body mass index (24.3 vs 28.2; P < 0.001) compared with controls. Compared with the CKD group, the mean operation time was longer in the control group (181.5 min vs 151.6 min; P = 0.02) and the estimated blood loss was greater (232 ml vs 165 ml; P = 0.004). Postoperative infection was more common in the CKD group (60%vs 40%; P = 0.01). There were no significant differences in reoperation rates, 30-day readmissions or the incidence of acute renal failure (ARF). CONCLUSION Patients with CKD Stages 3 and 4 had a higher incidence of postoperative infections than matched controls after colorectal surgery. ARF developed in 18.6% of patients. Preoperative optimization should include adequate hydration and assessment of potentially nephrotoxic substances for bowel preparation, preoperative antibiotics and pain control.

Abstract
AIM The aim of this study was to analyse postoperative infection in patients undergoing surgery for Crohn's disease (CD) according to the use of preoperative immunosuppressants, including infliximab. METHOD With IRB approval, the records of all patients with CD who underwent abdominal surgery between 2001 and 2008 were reviewed for comorbidity, preoperative medication, type of surgery, stoma construction and postoperative complications. Patients were divided into three categories according to the preoperative medication within 90 days of surgery as follows: infliximab (IFX), other drugs including steroids and/or immunosuppressive agents (OD) and no drugs (ND). RESULTS Two hundred and twenty-five patients were identified. Preoperative comorbidity, surgical indication and type of surgery were not significantly different among the three groups. Ileocolic resection was the most common procedure [50.8%, IFX group; 61.2%, OD group; 41.3%, ND group (P = 0.09)]. Other procedures included total colectomy (16%), protectomy (15%) and others (18%). Laparoscopic surgery was performed in 47.7%, 45.9% and 29.3% of patients in the IFX, OD and ND groups, respectively (P = 0.04). There were no differences in postoperative rates of infection [pneumonia (P = 0.14), wound infection (P = 0.35), abscess (P = 0.34) or anastomotic leakage (P = 0.44)]. Reoperation was needed in 3.0%, 8.2% and 2.6% of patients in the IFX, OD and ND groups, respectively. Multiple logistic regression found no relationship between infliximab use and infection. CONCLUSION There was no difference in the rate of postoperative complications among the groups of patients undergoing surgery for CD pretreated with IFX or other immunosuppressive drugs.

Abstract
AIM The aim of the study was to correlate the presence and pattern of distribution of granulomas in resected specimens to clinical characteristics and outcome in patients undergoing surgery for Crohn's disease. METHOD Patients with Crohn's disease who underwent surgical resection between 2001 and 2007 were identified. Pathology slides were reviewed for the presence, number and location of granulomas in four representative slides from each specimen. RESULTS Two-hundred and seven patients were identified. At a mean follow up of 14 months, 39 patients had a recurrence, 22 (57%) of whom underwent reoperation. Ninety-four (45%) patients had granulomas present in the surgical specimen. Patients with granulomas were younger (P<0.001), had a lower preoperative body mass index (P=0.037), were more likely to be female (P=0.017) and were more likely to have extra-intestinal manifestations (P=0.026) or perianal disease (P=0.012). Sites of disease and procedures performed were similar in both groups. Disease recurrence and reoperative rates were similar in both groups, as were length of stay and morbidity rates. The average number of granulomas present in each sampled pathology slide was 7.2, and there was no correlation between number of granulomas and disease severity. No link was found between the depth of involvement of the granulomas and fistulizing or stricturing disease. CONCLUSION Granulomas were associated with increased extra-intestinal manifestations and perianal disease, a lower body mass index and younger or female patients. There was no correlation between the presence of granulomas and disease progression or recurrence rates during the short follow-up period of this study.

Abstract
BACKGROUND The balance between abdominal and perineal approaches for rectal prolapse is always the higher morbidity but better outcome in the former setting. Therefore, perineal approaches have been preferred for the treatment of full-thickness rectal prolapse (FTRP) in elderly patients. However, laparoscopic rectopexy with or without resection also may be used for elderly patients and may confer the same benefits. PURPOSE The objective of this study was to evaluate safety and efficacy of laparoscopic rectopexy compared with perineal rectosigmoidectomy for FTRP in elderly patients. METHODS Between July 2000 and June 2009, eight consecutive patients (8 women; mean age, 71 (range, 65-77) years) with FTRP underwent laparoscopic rectopexy (LAP group). During the same period, 143 patients underwent perineal rectosigmoidectomy (PRS group). A total of 123 patients were selected who underwent perineal rectosigmoidectomy (117 women; mean age, 80.7 (range, 66-98) years). RESULTS Three patients (37.5%) in the LAP group and 29 patients (23.6%) in the PRS group had undergone previous operations for rectal prolapse. The mean follow-up periods were 6.9 months and 12.8 months, respectively. In the LAP group, operative time was longer (166.5 vs. 73.5 minutes; p > 0.05) and bleeding loss was more (101.7 vs. 31.6; p < 0.05), whereas the length of hospitalization was same between the two groups (5.4 vs. 5.3 days; p > 0.05). Postoperative complications included an incisional hernia in the LAP group (12.5%) and urinary retention (4.8%), anastomotic disruption (2.4%), urinary tract infection (1.6%), and atelectasis (1.6%) in the PRS group (13.8%). Recurrences were 1 (12.5%) in the LAP group and 14 (11.4%) in the PRS group. CONCLUSIONS Laparoscopic rectopexy is a safe and feasible procedure in elderly patients with FTRP but results in increased operative time.

Abstract
AIM The aim of this study was to review the recent results of ileal pouch-anal anastomosis (IPAA) in elderly patients compared with younger patients. METHOD Retrospective evaluation was carried out based on a prospective Institutional Review Board approved database of patients who underwent IPAA from 2001 to 2008. Patients aged ≥ 65 years were matched with a group of patients aged < 65 years by gender, date of procedure, diagnosis and type of procedure performed. Preoperative and intra-operative data and early postoperative complications were obtained. RESULTS Thirty-three patients (22 women), 32 with mucosal ulcerative colitis, were included in each group. The elderly group had a mean age of 68.7 years, body mass index of 27 kg/m², duration of disease of 17.4 years, high American Society of Anesthesiologists (ASA) score and high incidence of comorbid conditions (87.9% had one or more). Dysplasia and carcinoma were the indication for the surgery in more than 50% of patients, followed by refractory disease (24.4%). The matched younger group had a mean age of 36.9 years, body mass index of 25.4 kg/m², shorter duration of disease (8.1 years; P = 0.001), lower ASA score (P = 0.0001) and lower comorbidity (42.4%; P = 0.0002). Operative data were similar for both groups. The elderly group had a higher rate of rehospitalization for dehydration (P = 0.02). Other medical complications (30 vs 27%) and surgical postoperative complications (33 vs 24%) were similar for both groups. The long-term function and complications were comparable for the groups. CONCLUSION Elderly patients who underwent IPAA had more comorbid conditions than younger patients. Except for rehospitalization for dehydration, medical and surgical postoperative complications were not different in the two groups.

Abstract
BACKGROUND Recent studies have shown improved outcomes after laparoscopic colorectal surgery compared with laparotomy for surgery for both benign and malignant colorectal diseases, including inflammatory bowel disease (IBD). This study was designed to evaluate the results of laparoscopic colorectal resections in normal weight patients compared with overweight and obese patients with IBD. METHODS A retrospective analysis of a prospectively acquired institutional review board-approved surgical database was performed. All consecutive patients with IBD who underwent laparoscopy from January 1, 2000 to April 30, 2008 were reviewed. BMI, age, gender, comorbidities, ASA classification, and surgical- and disease-related variables, including 60-day postoperative complications, were reviewed. Chi-square, Mann-Whitney U test, and Student's t test were used for statistical analysis. RESULTS A total of 261 patients with IBD underwent laparoscopy: 48 were excluded and 213 were analyzed. Group I comprised 127 normal-weight patients (body mass index (BMI), 18.5-24.9 kg/m(2)), and group II included 67 overweight patients (BMI, 25-29.9 kg/m(2)) and 19 obese patients (BMI >or= 30 kg/m(2)). Crohn's disease was diagnosed in 86 (67.7%) patients in group I and 52 (60.4%) in group II. Procedures performed included ileocolic resection in 56% of patients in each group. Total colectomy with or without proctectomy was undertaken in 39.4% in group I and 40.7% in group II. The conversion rate was 18% for group I and 22.09% for group II (p > 0.005; not significant). The most common reason for conversion was failure to progress due to adhesions or phlegmon. There were no differences in major postoperative complication rates (wound infection, abscess, anastomotic leakage, or small-bowel obstruction) or mean hospital stay (6.7, 6.8, respectively), and there was no mortality. CONCLUSIONS Patients with IBD who were overweight or obese and who underwent laparoscopic bowel resection had no significant differences in the rates of conversion, major postoperative complications, or length of stay when comparing to patients with normal BMI. Therefore, the benefits of laparoscopic bowel resection should not be denied to overweight or obese patients based strictly on their BMI.
