[Fast track recovery protocols for extended pelvic surgery]. / Protokoly uskorennogo vyzdorovleniya pri rasshirenno-kombinirovannykh operatsiyakh na organakh malogo taza.

OBJECTIVE: To compare the immediate results of extended pelvic surgery before and after introduction of standardized fast track surgery (FTS) protocol into routine clinical practice. MATERIAL AND METHODS: The study included 111 patients with pelvic tumors who underwent extended pelvic surgery. The control group included 59 patients whose perioperative management implied traditional approaches (2018-2019), the main group - 52 patients with FTS protocol (2020-2021). Age, BMI and ECOG status were similar. In the main group, females (90.4% vs. 74.6%; p=0.046), patients with recurrent (46.2% vs. 22.0%; p=0.009) and complicated tumors (26.9% vs. 11.9%; p=0.054) prevailed. Obstructive resection without anastomosis was less common in the main group (28.8% vs. 47.5%; p=0.068). RESULTS: Surgery time was higher (319±125 min vs. 236±79 min, p<0.001) in the main group, but blood loss (238±154 ml vs. 282±150 ml, p=0.029) and incidence of blood transfusions (23.1% vs. 42.4%, p=0.043) were lower. Moreover, complications (36.6% vs. 54.3%; p=0.086), mild complications (Clavien-Dindo class I-II) (11.6% vs. 28.8%; p=0.034) and local infectious complications (19.2% vs. 42.4%; p=0.009) were less common in the main group. Two patients died in the control group due to sepsis following colonic anastomosis and bladder suture failure, respectively. Postoperative hospital-stay was similar (14±9.1 days vs. 14.4±9 days; p=0.89). CONCLUSION: FTS protocol is possible and safe in patients with locally advanced and recurrent malignant pelvic tumors. This approach reduces blood loss, the number of blood transfusions and risk of postoperative infections.

[The alteration of the structure of mortality of endocrine system diseases, nutrition disorders and metabolic disturbances in individuals of able-bodied age and older in conditions of pandemic].

The elderly age and endocrine diseases are among death risk factors at contamination with new coronavirus infection. To reply the question of how the influence of these risk factors is summing up, differences were determined concerning patterns of changes in structure of mortality of endocrine system diseases, nutrition disorders and metabolic disturbances in individuals of able-bodied age and older against the background of COVID-19 pandemic. on the basis of information from the Moscow database of deaths of endocrine system diseases, nutrition disorders and metabolic disturbances, the changes in contribution of individual diseases to the death causes structure in 2019-2021 were analyzed. The groups of individuals of able-bodied age and older were compared. It was established that in both groups rate of indicating SARS-CoV-2 virus infection as concomitant disease decreased while rate of indicating concomitant diseases at death of COVID-19 increased. The group differences in changes of structure of death causes were established in 2021. The percentage of undetermined forms of diabetes and obesity in structure of death causes increased in the elderly, while in individuals of able-bodied age increased. The percentage of obesity as concomitant disease of death of COVID-19 in individuals of able-bodied age increased and did no change were detected in the elderly group. The input of poly-glandular dysfunction as consequence of old infection into mortality is five times higher among individuals of able-bodied age. On the basis of received results, assumption was made SARS-CoV-2 virus contamination ruinously affects development of pathological process under endocrine diseases regardless of age, while age affects spreading of endocrine diseases and degree of resistance to development of infectious process directly. The differences in patterns of changes of structure of death causes of population of able-bodied age and older are associated with low quality of diagnostics of death causes in individuals of elder age groups.

[Quality of accounting of death causes for elderly people].

Programs to increase the life expectancy of old people are becoming increasingly relevant in an aging society. Their adequacy depends on the quality of accounting death causes. Objective: To evaluate the quality of accounting of death causes for population over the working age. For 98 061 deaths of people over working age registered in Moscow dead database, the structure of underline and multiple causes of death were compared. To determine whether information on morbidity of elderly can improve the diagnosis of death causes the structure of death causes was compared with officially registered prevalence and detected prevalence. The last was calculated on the basis of the household survey of health of elderly population in Nizhny Novgorod Region (22 558 people). We find fundamental difference between the structure of causes for officially registered prevalence, detected prevalence and mortality. In the structure of death causes the nervous diseases are in the second place and the proportion of uncertain death causes is 6.7%. The difference in the structure of underline and multiple causes of death is not so great. For people over working age, the coding errors were detected in 9.8% underline death causes. Thus, morbidity statistics cannot provide informational support for diagnosing causes of death in full. To improve the quality of accounting of death causes, it is advisable to introduce the institution of coders and to give them the possibility of verifying death diagnoses in medical organizations where the diagnosis has been established.

[C-reactive protein as early predictor of anastomotic leakage after surgery for colorectal cancer. Systematic review and meta-analysis]. / S-reaktivnyi belok kak rannii marker nesostoyatel'nosti shvov tolstokishechnogo anastomoza posle rezektsii tolstoi kishki po povodu raka. Sistematicheskii obzor i metaanaliz.

OBJECTIVE: Systematic review and meta-analysis of data on C-reactive protein (CRP) as a predictor of anastomotic leakage (AL) after surgery for colorectal cancer. MATERIAL AND METHODS: Literature searching was performed in Medline, Elibrary, Scopus, Web of Science databases. Literature request consisted of keywords «CRP¼, «colorectal surgery¼, «anastomotic leakage¼ for the period 2008-2018. Meta-analysis included 2 manuscripts for the second postoperative day, 7 articles for the third postoperative day and 6 articles for the fourth postoperative day. ROC-analysis was made to determine optimal prognostic values. RESULTS: ROC-curve for the second postoperative day - AUC 0.758; optimal CRP value - 154 mg/l (sensitivity 70.1%, specificity 55.6%), 95% confidence interval 0.698-0.819. ROC-curve for the third postoperative day - AUC 0.715; optimal CRP value - 144.5 mg/l (sensitivity 79.1% specificity 60.3%), 95% confidence interval 0.68-0.75. ROC-curve for the fourth postoperative day - AUC 0.767; optimal CRP value - 122.91 mg/l (sensitivity 72.3% specificity 60%), 95% confidence interval 0.73-0.804. CONCLUSION: Increased CRP is an early predictor of AL after surgery for colorectal cancer. CRP level ≥144.5 mg/l on the third postoperative day can predict AL (sensitivity 79%, specificity 60%).

[The mortality of diabetes mellitus from the perspective of multiple causes of death: encoding problems].

The statistics of causes of death is the informational basis for identifying public health problems. That is why the accurately accounting for mortality from diabetes mellitus, which is a global medical and social problem for society, is important. The study was carried out to analyze the correctness of coding death causes of diabetes mellitus and the frequency of alleged death. MATERIALS AND METHODS: The Moscow deceased population database of July 2018 - July 2019 was analyzed. Using the decision tables on codes linkages from ICD-10, incorrect codes for underline cause were established for 342 death cases from diabetes mellitus. Among 43044 cases of cardiovascular death the cases of presumed death from diabetes were detected. The analysis was carried out in the Microsoft Access 2007 software. THE RESULTS: In 18.4% of cases, the cause of death from diabetes was encoded incorrectly. If a modification of the underline death cause is assumed due to the mention of certain diseases in any line of the Death Certificate, cases of coding for death from diabetes with wrong fourth character are more often detected when mentioning kidney diseases. If modification of the underline cause is provided for cases when information in the Death Certificate indicates that diabetes has caused the development of some diseases then the largest number of cases with incorrect coding was detected when mentioning circulatory diseases. Only in one medical organization the frequency of incorrect coding is 3.4%, in the rest it varies from 15.4% to 52.2%. Among all death causes, diabetes was only 0.41%. If to add cases of presumptive death from diabetes mellitus, then the proportion of diabetes in the structure of death causes will almost triple and reach up to 1.2%. CONCLUSIONS: The quality of diagnosis and coding of death causes from diabetes has not improved in recent years. To increase it, it is advisable to organize and establish the institution of coders. It is advisable to indicate the presence of diabetes mellitus in the Death Certificate without fail and use the information from the diabetes register. It is proposed to encode the death cause from diabetes mellitus with multiple complications use line D in the Death Certificate to indicate damage to various organs and systems if it is necessary.
