Geriatric approach to the treatment of senile patients with colorectal cancer

Introduction. The lack of consensus guidelines for the treatment of colorectal cancer (CRC) in senile patients, the high incidence of early postoperative complications after radical surgery caused the search for the most optimal approach to the management of this category of patients.The aim is to introduce a geriatric approach to the treatment of colorectal cancer in senile patients, reduce the incidence of Clavien–Dindo grade 4 early postoperative complications.Materials and methods. 190 senile patients who underwent radical surgery with D3 lymphadenectomy with stage II and III colorectal cancer were enrolled in the study. They were divided into two groups: the control group included 100 patients who underwent standard treatment, the study group included 90 patients, to whom the geriatric approach with a comprehensive geriatric assessment (CGA) and subsequent pre-rehabilitation was applied. A comparative intergroup analysis was performed on the basis of obtained data.Results. The study group differed from the control group in higher polymorbidity and high operational and anesthetic risk (p <0.001). Implementation of geriatric pre-rehabilitation with due account for CGA results and correction of polymorbidity improved chances of providing surgical care using laparoscopic and robotic technologies. The frequency of intraoperative blood transfusion and prolonged mechanical ventilation in the study group was reduced (p <0.001 and p = 0.009, respectively). Predictors that increase the chances of developing acute postoperative myocardial infarction were identified. They included the patient’s male gender (p = 0.004), redo surgery after development of early postoperative complications (p = 0.043), prolonged mechanical ventilation (p = 0.052), increased length of stay in the intensive care unit (p = 0.011), and comorbidity (p = 0.022). The introduction of the geriatric approach made it possible to reduce the risk of postoperative myocardial infarction by 17.86 times (p = 0.007).Conclusion. The geriatric approach to the senile patients with colorectal cancer makes it possible to expand the indications for radical treatment in severe polymorbidity and senile asthenia, as well as to reduce the incidence of early postoperative complications

Diagnosis and Treatment of Elderly and Senile Chronic Constipation: an Expert Consensus

Aim. An appraisal of practitioners with chronic constipation management details in older and senile adults.Key points. Chronic constipation is a common issue in geriatrics. Aside to age-related physiological bowel disfunction, a higher constipation incidence is conditioned by declined physical activity and frailty, polypharmacy and a series of secondary constipation-developing chronic states and diseases. Chronic constipation is associated with a higher risk of cardiovascular disease and complications, impaired general perception of health and pain, growing alarm and depression, and reduced quality of life. The treatment tactics in chronic constipation is cause-conditioned and should account for the patient’s history and therapy line, overall clinical condition, cognitive status and functional activity level. An essential baseline aspect of constipation management is apprising the patient and his family of the underlying factors and methods for non-drug and drug correction. An higher-fibre diet is recommended as first measure, with osmotic laxatives added and titrated to clinical response if none observed towards the non-drug and high-fibre regimens. Stimulant laxatives and prokinetics should be recommended in patients reluctant to fibre supplements and osmotic laxatives. Subsidiary correction includes biofeedback, transanal irrigation, acupuncture, foot reflexology and percutaneous tibial nerve stimulation.Conclusion. Elderly and senile chronic constipation is a prevalent multifactorial state requiring an efficient management via assessment and correction of total risk factors and consistent use of non-medication and drug therapies

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

Efficacy of combined colorectal cancer treatment in senile patients

Aim of investigation.To estimate efficacy of combined treatment of colorectal cancer (CRC) in senile patients, to determine risk factors for postsurgical complications and evaluate postoperative mortality. Material and methods. The retrospective and prospective analysis of primary CRC patients, who were operated in The First Sechenov Moscow State Medical University and Petrovsky National Research Center of Surgery in April, 2006 to May, 2014 was carried out. Overall 122 patients with CRC of the II-IV stage of senile age were selected, whose mean age was 79 (75-95) years. Preoperative comorbidity assessment and perioperative complications risk were assessed by Charlson comorbidity index and ASA physical status classification system. Cr-POSSUM scoring system was applied to predict postoperative (30-day) mortality. Overall and cancer-specific survival rate were assessed taking into account comorbidity of patients and prescribed adjuvant therapy. Results. The average Charlson score taking into account age of the patient was 7.6±2.4. Forty seven patients (39%) were classified as ASA≥3. The predicted postoperative motility (Cr-POSSUM) was 13.2%. In 106 (87%) patients colon or rectum resection with formation of primary interintestinal anastomosis and D3 lymph node dissection, at 11 (9%) - abdominal and perineal rectum extirpation is executed, 5 patients had obstructive Hartmann operation. Patients with the IV stage of CRC underwent standard volume surgery with high-grade lymph node dissection due to the high risk of obstruction or tumor bleeding. Achieved 30-day postoperative mortality was 4.9%, overall 5-year survival rate - 67.3±5.6%, cancer-specific survival - 70.1±4.4%. In group of patients with III and IV stages of CRC who received postoperative adjuvant therapy, the tendency to higher total survival was noted, however only cancer-specific survival scores had statistically significant differences in this subgroup. Conclusions. Multidisciplinary approach to CRC treatment provides achievement of satisfactory postoperative mortality in senile patients (4.9% versus predicted 13.2%) along with satisfactory total and cancer-specific 5-year survival rate. Postoperative adjuvant therapy significantly improves treatment results for third stage CRC, however the objective indications for adjuvant therapy are yet to be established. Due to complex drugto-drug interactions specificity of metabolism and biological tumor properties, cross-reactions of concomitant diseases in senile patients each step of combined treatment should be discussed at multidisciplinary consultation

Primary Screening of Microorganisms against <i>Meloidogyne hapla</i> (Chitwood, 1949) under the Conditions of Laboratory and Vegetative Tests on Tomato

Highly adapted obligate endoparasites of the root system, root-knot nematodes (Meloidogyne spp.), cause great damage to agricultural crops. Our research is aimed at the assessment of nematicidal activity and effectiveness of antagonist fungal and bacterial strains against the most common type of root-knot nematode in the south of Russia. By means of molecular genetic identification, it was found that in the south of Russia, the species Meloidogyne hapla Chitwood, 1949 and Meloidogyne incognita (Kofoid and White, 1919) Chitwood, 1949 cause galls on the roots of open-ground and greenhouse tomato. Screening of microbial agents against second-stage juvenile (J2) M. hapla was carried out in the laboratory. At the end of the experiment, two liquid fungal cultures of Paecilomyces lilacinus BK-6 and Metarhizium anisopliae BK-2 were isolated, the nematicidal activity of which reached 100.0 and 70.2%, and exceeded the values of the biological standard (Nemotafagin-Mikopro) by 38.4% and 8.8%. The highest biological efficacy was noted in the liquid cultures of P. lilacinus BK-6, M. anisopliae BK-2, and Arthrobotrys conoides BK-8 when introduced into the soil before planting tomato. The number of formed galls on the roots was lower in comparison with the control by 81.0%, 75.5%, and 74.4%

Screening policies, preventive measures and in-hospital infection of COVID-19 in global surgical practices

Background: In a surgical setting, COVID-19 patients may trigger in-hospital outbreaks and have worse postoperative outcomes. Despite these risks, there have been no consistent statements on surgical guidelines regarding the perioperative screening or management of COVID-19 patients, and we do not have objective global data that describe the current conditions surrounding this issue. This study aimed to clarify the current global surgical practice including COVID-19 screening, preventive measures and in-hospital infection under the COVID-19 pandemic, and to clarify the international gaps on infection control policies among countries worldwide. Methods: During April 2-8, 2020, a cross-sectional online survey on surgical practice was distributed to surgeons worldwide through international surgical societies, social media and personal contacts. Main outcome and measures included preventive measures and screening policies of COVID-19 in surgical practice and centers' experiences of in-hospital COVID-19 infection. Data were analyzed by country's cumulative deaths number by April 8, 2020 (high risk, &gt;5000; intermediate risk, 100-5000; low risk, &lt;100). Results: A total of 936 centers in 71 countries responded to the survey (high risk, 330 centers; intermediate risk, 242 centers; low risk, 364 centers). In the majority (71.9%) of the centers, local guidelines recommended preoperative testing based on symptoms or suspicious radiologic findings. Universal testing for every surgical patient was recommended in only 18.4% of the centers. In-hospital COVID-19 infection was reported from 31.5% of the centers, with higher rates in higher risk countries (high risk, 53.6%; intermediate risk, 26.4%; low risk, 14.8%; P &lt; 0.001). Of the 295 centers that experienced in-hospital COVID-19 infection, 122 (41.4%) failed to trace it and 58 (19.7%) reported the infection originating from asymptomatic patients/staff members. Higher risk countries adopted more preventive measures including universal testing, routine testing of hospital staff and use of dedicated personal protective equipment in operation theatres, but there were remarkable discrepancies across the countries. Conclusions: This large international survey captured the global surgical practice under the COVID-19 pandemic and highlighted the insufficient preoperative screening of COVID-19 in the current surgical practice. More intensive screening programs will be necessary particularly in severely affected countries/institutions
