Safety of gastric bypass with same-day discharge: a propensity score-matched analysis of the Dutch Audit for treatment of Obesity

BackgroundBariatric surgery with same-day discharge (SDD) is becoming increasingly common. Nevertheless, there is limited data available comparing gastric bypass patients with SDD to those with overnight hospitalization. ObjectiveThe aim of this study was to investigate the short-term outcomes of gastric bypass with SDD compared to overnight hospitalization in The Netherlands. SettingRetrospective database study with the use of the Dutch national registry. MethodsPatients who underwent gastric bypass surgery in 2022 were included and propensity score matching was performed to compare SDD with patients discharged on postoperative days (POD) 1-4. The primary outcome was the occurrence of severe complications within 30 days postoperative. ResultsA total of 775 SDD patients were matched with 1550 patients discharged on POD 1-4. The occurrence of severe complications was .9% in both groups (P = 1.000), and there were no significant differences in reoperations or mortality. A significant difference was observed in the readmission rate, with 3.9% in the SDD group compared to 1.6% in the other group (P = .001). A proportionally small, yet statistically significant difference favored the control group regarding anastomotic leakages (.6% versus 0%, P = .004) and unspecified surgical complications (1.4% versus .5%, P = .028). ConclusionGastric bypass with SDD is safe, with no increased risk of short-term severe complications, reoperations, or mortality. However, SDD is associated with a higher 30-day readmission rate compared to patients who stay overnight in the hospital after surgery.

Analysis of the learning curve for laparoscopic pancreaticoduodenectomy based on a single surgeon's experience: a retrospective observational study.

Laparoscopic pancreaticoduodenectomy (LPD) is a highly challenging procedure, which prevents its widespread adoption despite its advantages of being a minimally invasive procedure. This study analyzed the learning curve for LPD based on a single surgeon's experience. We retrospectively analyzed the medical records of 111 consecutive patients who underwent LPD by a single surgeon between March 2014 and October 2022. The learning curve was assessed using cumulative summation (CUSUM) and risk-adjusted CUSUM (RA-CUSUM) methods. Surgical failure was defined as conversion to an open procedure or the occurrence of severe complications (Clavien-Dindo grade ≥III). Based on the learning curve analysis, we divided the learning curve into the early and late phases and compared the operative outcomes in each phase. Based on the CUSUM analysis, the operation time decreased after the first 33 cases. Based on the RA-CUSUM analysis, the LPD technique stabilized after the 44th case. In the late phase, operation time, length of stay, and incidence of delayed gastric emptying, severe complications, and surgical failure were significantly lower than in the early phase. Our results indicate that 44 cases are required for stabilization of the LPD technique and improvement of operative outcomes.

Tracheal Intubation and Mechanical Ventilation in Adults with Severe Salicylate Poisoning

BackgroundSalicylate poisoning may lead to critical acid-base disturbances. Tracheal intubation and mechanical ventilation for patients with severe salicylism has been strongly discouraged. ObjectiveThis study aims to describe pH trends, complications, and outcomes in a cohort of salicylate-poisoned patients who were intubated. MethodsThis retrospective observational study included adults presenting to the emergency department (ED) with severe salicylate poisoning (serum salicylate concentration > 40 mg/dL and admission to an intensive care unit [ICU]) over a 14-year period (2007-2021). The primary and secondary outcomes were the change in serum pH and the occurrence of severe complications (systolic blood pressure < 80 mm Hg, oxygen saturation < 80%, or cardiac arrest), respectively, in the 6 hours after presentation. ResultsAmong 32 adults with severe salicylate poisoning (median serum salicylate level 64.2, interquartile range [IQR] 52.5 to 70.7), 11 (34%) underwent tracheal intubation. The initial mean pH (± SD) in the no intubation group was 7.48 ± 0.07 and was 7.36 ± 0.04 in the intubation group. The mean absolute difference in pH measured before and after intubation was -0.02 (95% CI -0.11 to 0.07). No severe complications were observed during or up to 6 hours after tracheal intubation and mechanical ventilation. ConclusionIn our single-center experience managing adults with severe salicylate poisoning, tracheal intubation and mechanical ventilation were not associated with substantial perturbation of serum pH or severe complications. These findings challenge the current paradigm that these interventions should be avoided in salicylate-poisoned patients.

Combining systemic inflammatory response index and albumin fibrinogen ratio to predict early serious complications and prognosis after resectable gastric cancer.

Gastric cancer has a high incidence and fatality rate, and surgery is the preferred course of treatment. Nonetheless, patient survival rates are still low, and the incidence of major postoperative complications cannot be disregarded. The systemic inflammatory response, nutritional level, and coagulation status are key factors affecting the postoperative recovery and prognosis of gastric cancer patients. The systemic inflammatory response index (SIRI) and the albumin fibrinogen ratio (AFR) are two valuable comprehensive indicators of the severity and prognosis of systemic inflammation in various medical conditions. To assess the clinical importance and prognostic significance of the SIRI scores and the AFR on early postoperative outcomes in patients undergoing radical gastric cancer surgery. We conducted a retrospective analysis of the clinicopathological characteristics and relevant laboratory indices of 568 gastric cancer patients from January 2018 to December 2019. We calculated and compared two indicators of inflammation and then examined the diagnostic ability of combined SIRI and AFR values for serious early postoperative complications. We scored the patients and categorized them into three groups based on their SIRI and AFR levels. COX analysis was used to compare the three groups of patients the prognostic value of various preoperative SIRI-AFR scores for 5-year overall survival (OS) and disease-free survival (DFS). SIRI-AFR scores were an independent risk factor for prognosis [OS: P = 0.004; hazards ratio (HR) = 3.134; DFS: P < 0.001; HR = 3.543] and had the highest diagnostic power (area under the curve: 0.779; 95% confidence interval: 0.737-0.820) for early serious complications in patients with gastric cancer. The tumor-node-metastasis stage (P = 0.001), perioperative transfusion (P = 0.044), positive carcinoembryonic antigen (P = 0.014) findings, and major postoperative complications (P = 0.011) were factors associated with prognosis. Preoperative SIRI and AFR values were significantly associated with early postoperative survival and the occurrence of severe complications in gastric cancer patients.

Stress-induced urgent conditions in endocrinology

The literature review deals with the influence of chronic stress on the functioning of the endocrine system. The most significant pathological conditions induced by chronic stress are decompensation of carbohydrate metabolism, disorders of the thyroid gland, reproductive system, depressive disorders, electrolyte disorders. The significance of these pathologies is determined by a pronounced decrease in the quality of life, the occurrence of severe complications, and an increase in mortality. The development of hyperglycemia during the acute period of the disease is an established connection between the stress system and glucose homeostasis, which is confirmed by the development of stress hyperglycemia and increased morbidity. Glucocorticoids have a contrainsular effect, and the significance of their impact on carbohydrate metabolism is due to the pleiotropic action: induction of insulin resistance, stimulation of gluconeogenesis, increase in the blood content of glucagon due to dysregulation of its synthesis and secretion. The effects of stress on the thyroid gland are determined by its duration, characterized by the activation of the pituitary-thyroid system in the acute period and its suppression during long-term and chronic stress. The contribution of the stress component and glucocorticoid deficiency to the development of autoimmune thyroid diseases due to the suppression of cellular and strengthening of humoral immunity is discussed. Under conditions of psychological stress, the development of hypothyroidism was noted in emigrants with anxiety-depressive syndrome and insomnia, as evidenced by a decrease in the concentration of thyroid hormones. A decreased thyroid status in these patients is associated with the severity of chronic stress. Research data show that chronic stress can significantly change a person’s thyroid status, leading to the development of triiodothyronine deficiency syndrome and an increase in the production of inactive reverse triiodothyronine, inducing the development of hypothyroidism. It is possible that the pronounced growth of subclinical forms of hypothyroidism, noted in many countries of the world, is a consequence of chronic stress. The hypothalamic-pituitary-adrenal axis is involved in the formation of stress-induced reactions almost immediately after exposure to the stressor. Stress-induced changes in the endocrine system arise and develop in close connection, forming a vicious circle of pathological changes and emergencies.

Long-term outcomes of pelvic exenterations for gynecological malignancies: a single-center retrospective cohort study

BackgroundRecently, with the advancement of medical technology, the postoperative morbidity of pelvic exenteration (PE) has gradually decreased, and it has become a curative treatment option for some patients with recurrent gynecological malignancies. However, more evidence is still needed to support its efficacy. This study aimed to explore the safety and long-term survival outcome of PE and the feasibility of umbilical single-port laparoscopic PE for gynecologic malignancies in a single medical center in China.Patients and methodsPE for gynecological cancers except for ovarian cancer conducted by a single surgical team in Sun Yat-sen University Cancer Center between July 2014 and December 2019 were included and the data were retrospectively analyzed.ResultsForty-one cases were included and median age at diagnosis was 53 years. Cervical cancer accounted for 87.8% of all cases, and most of them received prior treatment (95.1%). Sixteen procedures were performed in 2016 and before, and 25 after 2016. Three anterior PE were performed by umbilical single-site laparoscopy. The median operation time was 460 min, and the median estimated blood loss was 600 ml. There was no perioperative death. The years of the operations was significantly associated with the length of the operation time (P = 0.0018). The overall morbidity was 52.4%, while the severe complications rate was 19.0%. The most common complication was pelvic and abdominal infection. The years of surgery was also significantly associated with the occurrence of severe complication (P = 0.040). The median follow-up time was 55.8 months. The median disease-free survival (DFS) was 17.9 months, and the median overall survival (OS) was 25.3 months. The 5-year DFS was 28.5%, and the 5-year OS was 30.8%.ConclusionPE is safe for patient who is selected by a multi-disciplinary treatment, and can be a curative treatment for some patients. PE demands a high level of experience from the surgical team. Umbilical single-port laparoscopy was a technically feasible approach for APE, meriting further investigation.

Safety and Efficacy Analysis of Radical Surgery for 403 Patients with Colon Cancer over 80 Years Old.

Aim: To investigate the safety and efficacy of radical surgery in colon cancer patients over 80 years old. Methods: Data from colon cancer patients aged ≥80 years who underwent radical surgery at the Cancer Hospital of the Chinese Academy of Medical Sciences and affiliated Heji Hospital of Changzhi Medical College from January 2011 to December 2022 were retrospectively analysed. Data on clinical characteristics, pathological features, perioperative data, and long-term prognosis were collected. Severe complications were classified as grade III-V. Logistic regression models were used to identify the risk factors for severe postoperative complications, and a Cox regression model was used to determine prognostic variables. Results: A total of 403 eligible patients were included in the study. A total of 118 (29.3%) patients developed postoperative complications, of which 51 (12.7%) experienced grade 3-5 severe complications. Two (0.5%) patients died of pulmonary embolism and myocardial infarction during the perioperative period. The multivariate logistic regression analysis showed that preoperative albumin levels <35 g/L and right colon cancer were independent risk factors for grade 3-5 postoperative complications. In terms of prognosis, multivariate analysis revealed that overall survival was significantly affected by TNM stage III and grade 3-4 postoperative complications. In addition, TNM stage III and perineural invasion were the independent prognostic factors for disease-free survival. Conclusion: Radical surgery can be performed safely in elderly colon cancer patients aged over 80 years, with an acceptable morbidity and mortality. Patients with preoperative albumin levels <35 g/L or tumors in the right colon should be alerted to the development of severe postoperative complications. In addition, the occurrence of severe complications can significantly affect the prognosis of elderly colon cancer patients.

Combined Interval Cytoreductive Surgery and Carboplatin-Based Hyperthermic Intraperitoneal Chemotherapy in Advanced Primary High-Grade Serous Ovarian Cancer.

Combining interval cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) improves survival in advanced epithelial ovarian carcinoma (EOC). Although limited, growing evidence regarding carboplatin-based HIPEC highlights its potential. This retrospective study included all patients with advanced primary high-grade serous ovarian cancer who underwent interval CRS combined with carboplatin-based HIPEC at our Canadian tertiary care center between 2014 and 2020. We identified 40 patients with a median age of 61 years. The median peritoneal cancer index was 13 and complete cytoreduction was achieved in 38 patients (95%). Median hospital stay was 13 days and there were four admissions to the intensive care unit (10%) and six readmissions (15%). Severe adverse events occurred in eight patients (20%) and there was no perioperative death. Recurrence was seen in 33 patients (82%) with a median DFS of 18.0 months and a median overall survival of 36.4 months. Multivariate analyses showed that age, peritoneal cancer index, completeness of cytoreduction, occurrence of severe complications, and bowel resection did not significantly impact DFS or OS in our cohort. Interval CRS combined with carboplatin-based HIPEC for advanced primary EOC is associated with acceptable morbidity and oncological outcomes. Larger studies are required to determine the long-term outcomes.

Rate of Complications after Hip Fractures Caused by Prolonged Time-to-Surgery Depends on the Patient's Individual Type of Fracture and Its Treatment.

Hip fractures are common injuries in the elderly and are usually treated with timely surgery. While severe postoperative complications are reported for up to 10% of patients, many studies identified predictive factors for the occurrence of complications postoperatively. A controversially discussed factor is "time-to-surgery". The aim of the study was to examine if time-to-surgery was associated with the occurrence of complications and if the complication rate differed between the patient individual fracture types of intracapsular on the one hand and extracapsular hip fractures on the other hand. We hypothesized that time-to-surgery had less impact on complications in intracapsular hip fractures compared to extracapsular ones, and therefore, guidelines should pay attention to the patient individual case scenario. All patients who were admitted to the Department of Trauma and Orthopaedic Surgery of an academic teaching hospital for hip fracture surgery (n = 650) over a five-year period were included in the study. After the application of the exclusion criteria, such as periprosthetic or pathologic fractures, cases needed immediate surgical treatment, and after outlier adjustment, 629 cases remained in the study. Hip fractures were classified into intracapsular fractures (treated by hip arthroplasty) and extracapsular fractures (treated by intramedullary nailing osteosynthesis). The occurrence of severe complications in patients treated within 24 h was compared with patients treated later than 24 h after injury. For statistical evaluation, a multivariate logistic regression analysis was performed to investigate the impact of time-to-surgery interval on the occurrence of complications. Patients with an extracapsular fracture, which was treated with intramedullary nailing (44.5%), rarely suffered a serious complication when surgery was performed within 24 h after injury. However, when the interval of the time-to-surgery was longer than 24 h, the complication rate increased significantly (8.63% vs. 25.0%, p = 0.002). In contrast to this finding in patients with intracapsular fractures (55.5%), which were treated with cemented arthroplasty, complication rates did not depend on the 24 h interval (26.17% vs. 20.83%, p = 0.567). The occurrence of complications after surgical treatment of hip fractures is associated with the time interval between injury and surgery. A 24 h time interval between injury and surgical procedure seems to play a major role only in extracapsular fractures treated with osteosynthesis but not in intracapsular fractures treated with arthroplasty. Therefore, guidelines should take notice of the patient individual case scenario and, in particular, the individual hip fracture type.

Open or Not Open the Retroperitoneum: A Pandora's Box for Blunt High-Grade Pancreatic Trauma?

IntroductionThe optimal management strategy for pancreatic trauma remains unclear. We aimed to determine whether the initial nonoperative management (NOM) strategy based on percutaneous drainage combined with endoscopic retrograde cholangiopancreatography guided stent placement would improve outcomes for blunt high-grade pancreatic trauma. MethodsPatients with blunt abdominal trauma who were hemodynamically stable without signs of diffuse peritonitis were consecutively enrolled at a high-volume center. The primary outcome was the occurrence of severe complications (Clavien‒Dindo classification ≥ Ⅲb) for patients who underwent initial laparotomy (LAP) versus NOM. Modified Poisson regression was used to model the primary outcome. Propensity score matching and weighting models were included into a regression-based sensitivity analysis. ResultsOf 119 patients with grade III/IV pancreatic trauma, 29 patients underwent initial NOM, and 90 underwent initial LAP. The incidence of severe complications in the LAP group was higher than that in the NOM group (65/90 [72.2%] versus 9/29 [31.0%], P < 0.001). In the multivariable modified Poisson regression model, the relative risk for severe complications was decreased in the NOM group (relative risk, 0.52; 95% confidence interval, 0.30-0.90; P = 0.020). The results of the sensitivity analysis were consistent with those of the multivariable analysis. The mean number of reinterventions per patient was 1.8 in the NOM group and 2.6 in the LAP group (P = 0.067). ConclusionsFor blunt high-grade pancreatic trauma patients with stable hemodynamics and no diffuse peritonitis, the NOM strategy was associated with a lower risk of severe complications (Clavien‒Dindo classification ≥ Ⅲb) and did not require more invasive reintervention procedures. In high-volume centers with sufficient expertise, percutaneous drainage combined with endoscopic retrograde cholangiopancreatography guided stent placement may serve as an initial reasonable option for selected patients.

Initial suction drainage decreases severe postoperative complications after pancreatic trauma: A cohort study.

Few studies have addressed the question of which drain types are more beneficial for patients with pancreatic trauma (PT). To investigate whether sustained low negative pressure irrigation (NPI) suction drainage is superior to closed passive gravity (PG) drainage in PT patients. PT patients who underwent pancreatic surgery were enrolled consecutively at a referral trauma center from January 2009 to October 2021. The primary outcome was defined as the occurrence of severe complications (Clavien-Dindo grade ≥ Ⅲb). Multivariable logistic regression was used to model the primary outcome, and propensity score matching (PSM) was included in the regression-based sensitivity analysis. In this study, 146 patients underwent initial PG drainage, and 50 underwent initial NPI suction drainage. In the entire cohort, a multivariable logistic regression model showed that the adjusted risk for severe complications was decreased with NPI suction drainage [14/50 (28.0%) vs 66/146 (45.2%); odds ratio (OR), 0.437; 95% confidence interval (CI): 0.203-0.940]. After 1:1 PSM, 44 matched pairs were identified. The proportion of each operative procedure performed for pancreatic injury-related and other intra-abdominal organ injury-related cases was comparable in the matched cohort. NPI suction drainage still showed a lower risk for severe complications [11/44 (25.0%) vs 21/44 (47.7%); OR, 0.365; 95%CI: 0.148-0.901]. A forest plot revealed that NPI suction drainage was associated with a lower risk of Clavien-Dindo severity in most subgroups. This study, based on one of the largest PT populations in a single high-volume center, revealed that initial NPI suction drainage could be recommended as a safe and effective alternative for managing complex PT patients.

Video versus Direct Laryngoscopy for Tracheal Intubation of Critically Ill Adults

BackgroundWhether video laryngoscopy as compared with direct laryngoscopy increases the likelihood of successful tracheal intubation on the first attempt among critically ill adults is uncertain.MethodsIn a multicenter, randomized trial conducted at 17 emergency departments and intensive care units (ICUs), we randomly assigned critically ill adults undergoing tracheal intubation to the video-laryngoscope group or the direct-laryngoscope group. The primary outcome was successful intubation on the first attempt. The secondary outcome was the occurrence of severe complications during intubation; severe complications were defined as severe hypoxemia, severe hypotension, new or increased vasopressor use, cardiac arrest, or death.ResultsThe trial was stopped for efficacy at the time of the single preplanned interim analysis. Among 1417 patients who were included in the final analysis (91.5% of whom underwent intubation that was performed by an emergency medicine resident or a critical care fellow), successful intubation on the first attempt occurred in 600 of the 705 patients (85.1%) in the video-laryngoscope group and in 504 of the 712 patients (70.8%) in the direct-laryngoscope group (absolute risk difference, 14.3 percentage points; 95% confidence interval [CI], 9.9 to 18.7; P<0.001). A total of 151 patients (21.4%) in the video-laryngoscope group and 149 patients (20.9%) in the direct-laryngoscope group had a severe complication during intubation (absolute risk difference, 0.5 percentage points; 95% CI, −3.9 to 4.9). Safety outcomes, including esophageal intubation, injury to the teeth, and aspiration, were similar in the two groups.ConclusionsAmong critically ill adults undergoing tracheal intubation in an emergency department or ICU, the use of a video laryngoscope resulted in a higher incidence of successful intubation on the first attempt than the use of a direct laryngoscope.

Inborn Errors of Immunity in Children with Autoimmune and Allergic Complaints: A Single Center Experience from Diagnosis to Treatment.

Inborn errors of immunity (IEI) associated with immune dysregulation are not sufficiently addressed in shared recommendation, resulting in delayed diagnosis and high morbidity. The availability of precision medicine for some of these immune defects makes it urgent to evaluate effective strategies to diagnose and treat such defects before the occurrence of severe complications. A diagnosis of an IEI in these patients enabled the use of a more specific treatment in most cases, and these have the potential to prevent further disease progression. We studied immune dysregulation diseases in 30 patients with autoimmune or allergic phenotypes, exploiting data from clinics and immunophenotype, genetic and transcriptome investigations, and 6 of them were diagnosed with a monogenic disorder. Our results confirm that a non-negligible number of children with IEIs may present with signs and symptoms of immune dysregulation and share many features with common multifactorial immune conditions. Reaching a genetic diagnosis becomes more likely in the presence of multiple clinical manifestations, especially when in association with abnormalities of lymphocytes subsets and/or immunoglobulins levels. Moreover, 5 of 6 patients that obtained a diagnosis of monogenic disorder received precision therapy, in four cases with a good or moderate response.

The Potential of Topical Therapy for Diabetic Wounds: A Narrative Review.

The rising prevalence of diabetes mellitus brings with it a rise in the occurrence of several complications of the disease such as chronic non-healing wounds. Diabetics are more prone to developing chronic wounds due to complications like peripheral neuropathy, poor foot care, hyperglycaemiaand peripheral vascular diseases. The aim of this review is to discuss the various imbalances in the cytokine environment of diabetic wounds and to explore the developments in their management with an emphasis on agents that may be used topically to aid the healing process of chronic wounds. A systematic search was conducted on Scopus, PubMed and Google Scholar and relevant articles were shortlisted. We conclude that increased blood sugar impairs mostphases of wound healing in several ways. Supplementary therapy with either topical or systemic cytokines is shown to promote wound healing in a diabetic wound.

Long-term evaluation of patients with BMI = 50kg/m2 who underwent Bariatric Surgery.

to determine the risks and benefits of bariatric surgery in patients with super obesity (SO) in comparison with obesity grades II and III. retrospective cohort that included a study group of 178 patients with SO and a control group of 181 patients with BMI 35-49.9Kg/m2. The groups were formed in a 1:1 nearest neighbor matching. The main variables were pre- and postoperative BMI and comorbidities, occurrence of severe postoperative complications, bowel obstruction, marginal ulcer, fistulae and 30-day death, besides the necessity of emergency room (ER) admission and abdominal computed tomography (CT) scans in the postoperative period due to acute abdomen. the study group comprised 74.0% of women while the control group had 56.7%. The mean follow-up time was similar between both groups (5.48 x 6.09 years, p=0.216). There was no statistically significant difference on the prevalence of hypertension and T2D between the groups according to the surgical technique. All deaths occurred in the Study group (BMI = 50kg/m2) who underwent RYGB. There was no difference between the groups regarding the occurrence of severe complications. Data on ER admissions and the need for abdominal CT to investigate postoperative abdominal pain did not show statistically significant difference between the groups. despite the high risk related to bariatric surgery in patients with SO, the benefits related to the remission of comorbidities are significant; although being lower than those found in patients with milder grades of obesity.

Risk Factors Indicating Difficulty During Gastric Endoscopic Submucosal Dissection for Inexperienced Endoscopists: A Retrospective Study.

Factors that may make endoscopic submucosal dissection (ESD) difficult for operators have been evaluated according to results based on the performance of experienced endoscopists. This study aimed to verify the predictors of difficult gastric ESD for ESD beginners. From January 2015 to December 2021, 466 superficial gastric neoplasms were treated with ESD at Showa University Hospital. Excluding 103 lesions that performed ESD by experts who experienced more than 80 ESDs, a total of 363 lesions were included. The lesions were divided into two groups according to the ESD performance experience of the operator:ESD beginner (EB; ESD experience≤30 cases) and ESD intermediate (EI; ESD experience 31-80 cases) groups. Relationships between difficult ESD (having at least one of the following: procedure time>60 min, incomplete resection, change of operator, and occurrence of severe complications) and clinicopathological findings of the lesion were analyzed. The complete resection rates and the difficult ESD rates in the EB and EI groups were 99.3%, 94.8%, and 61.2%, 50.7%, respectively. In the EB group, univariate analysis showed that difficult ESD rate was significantly higher in the non-lower third lesions, the lesser curvature lesions, and cancerous lesions. In the EI group, univariate analysis showed that difficult ESD rate was significantly higher in lesion with ≥20 mm size, lesser curvature lesions, lesions with ulcers, and submucosal cancers. Multivariate analysis showed that the lesser curvature location and cancerous histology in the EB group and ≥20 mm lesion size, the lesser curvature location and submucosal invasion in the EI group were independent predictors of difficult ESD. The lesser curvature location is recognized as independent ESD difficulty factor for both beginners and intermediates.Cases with lesions located in the lesser curvature should not be selected for gastric ESD training by beginners.

PECULIARITIES OF MOTOR ACTIVITY IN PRIMARY SCHOOL AGED CHILDREN DURING SPREAD OF ACUTE RESPIRATORY VIRAL INFECTIONS

This article represents the analysis of scientific literature on the issue of motor activity in primary school-age children. The concept of motor activity is considered, its characteristic features are given in the context of the studied age period. Motor activity, as one of the basic means of physical culture, provides many opportunities for solving a number of problems related to the normal physical development and health preservation. The use of various forms of physical culture contributes to the prevention of diseases, increase in life expectancy and work capacity, promotes active creative longevity, and helps in the organization of full-time leisure time and the eradication of bad habits, thus creating conditions for learning about one’s own capabilities. The data obtained from the analysis of scientific and methodical publications points out the insufficiency of motor activity in children of primary school age that leads to the development of hypodynamia and a decrease in their level of health. Influenza and acute respiratory viral infections are one of the most urgent medical and socio-economic problems not only in out country but abroad as well. This is due to the significant prevalence of the diseases, their complex course, high risk of mortality and the occurrence of severe complications. One of the most unprotected categories of population is children. This group of infections causes significant economic damage to both the household budget and the state budget in particular. Acute respiratory viral infections occupy leading positions in the structure of children's diseases. Almost every child experiences episodes of acute viral respiratory infections or flu more than once a year. There has been found out scanty literature devoted to the influence of acute viral respiratory infections on indicators of the motor activity in children. The analysis of this issue is particularly relevant in the context of the COVID-19 pandemic. Special attention is focused on the need to change the content of physical education curriculum in order to improve the effectiveness of the fight against acute viral respiratory infections.

Edmonton Symptom Assessment Scale may reduce medical visits in patients undergoing chemotherapy for breast cancer.

BACKGROUNDAdjuvant chemotherapy is recommended in high-risk breast cancer. However, no universally accepted guidelines exist on pre-chemotherapy assessment. In particular, the number and frequency of medical visits vary according to each institution’s policy. We hypothesised that the Edmonton Symptom Assessment Scale (ESAS) may have a favourable impact on the pre-treatment assessment in candidates for adjuvant chemotherapy.AIMTo investigate whether the ESAS can be used to safely reduce the number of medical visits in women with breast cancer undergoing adjuvant chemotherapy.METHODSIn a retrospectively prospective matched-pair analysis, 100 patients who completed the ESAS questionnaire before administration of adjuvant chemotherapy (ESAS Group) were compared with 100 patients who underwent chemotherapy according to the traditional modality, without ESAS (no-ESAS Group). Patients of the ESAS Group received additional visits before treatment if their ESAS score was > 3. The primary endpoint was the total number of medical visits during the entire duration of the chemotherapy period. The secondary endpoints were the occurrence of severe complications (grade 3-4) and the number of unplanned visits during the chemotherapy period.RESULTSThe study variables did not statistically differ between patients of the ESAS Group and no-ESAS Group (age P = 0.880; breast cancer stage P = 0.56; cancer histology P = 0.415; tumour size P = 0.258; lymph node status P = 0.883; immunohistochemical classification P = 0.754; type of surgery P = 0.157), except for premenopausal status (P = 0.015). The study variables did not statistically differ between patients of the ESAS Group and no-ESAS Group regarding age, cancer stage, histology, tumour size, lymph node status, immunohistochemical classification, and type of surgery. Unplanned visits during the entire duration of chemotherapy were 8 in the ESAS Group and 18 in the no-ESAS Group visits (P = 0.035). Grade 3-4 toxicity did not differ between the study groups (P = 0.652). Forty-eight patients of the ESAS Group received additional visits due to an ESAS score > 3. The mean number of medical visits was 4.38 ± 0.51 in the ESAS Group and 16.18 ± 1.82 in the no-ESAS group (P < 0.001). With multivariate analysis, women of the ESAS group were more likely to undergo additional visits for an ESAS score > 3 if they were aged 60 or older, received a mastectomy, or had tumour stage II/III.CONCLUSIONThe ESAS score may safely reduce the number of medical visits in candidates for adjuvant chemotherapy for early breast cancer. Our results suggest that the ESAS score may be used for selecting a group of breast cancer patients for whom it is safe to reduce the number of medical visits in the setting of adjuvant chemotherapy. This may translate into several advantages, such as a more rational utilization of human resources and a possible reduction of coronavirus pandemic infection risk in oncologic patients.

Effect of inotropic agents on oxygenation and cerebral perfusion in acute brain injury.

IntroductionTissue hypoxia and insufficient energy delivery is one of the mechanisms behind the occurrence of several complications in acute brain injured patients. Several interventions can improve cerebral oxygenation; however, the effects of inotropic agents remain poorly characterized.MethodsRetrospective analysis including patients suffering from acute brain injury and monitored with brain oxygen pressure (PbtO2) catheter, in whom inotropic agents were administered according to the decision of the treating physician's decision; PbtO2 values were collected before, 1 and 2 h after the initiation of therapy from the patient data monitoring system. PbtO2 “responders” were patients with a relative increase in PbtO2 from baseline values of at least 20%.ResultsA total of 35 patients were included in this study. Most of them (31/35, 89%) suffered from non-traumatic subarachnoid hemorrhage (SAH). Compared with baseline values [20 (14–24) mmHg], PbtO2 did not significantly increase over time [19 (15–25) mmHg at 1 h and 19 (17–25) mmHg at 2 h, respectively; p = 0.052]. A total of 12/35 (34%) patients were PbtO2 “responders,” in particular if low PbtO2 was observed at baseline. A PbtO2 of 17 mmHg at baseline had a sensibility of 84% and a specificity of 91% to predict a PbtO2 responder. A significant direct correlation between changes in PbtO2 and cardiac output [r = 0.496 (95% CI 0.122 to 0.746), p = 0.01; n = 25] and a significant negative correlation between changes in PbtO2 and cerebral perfusion pressure [r = −0.389 (95% CI −0.681 to −0.010), p = 0.05] were observed.ConclusionsIn this study, inotropic administration significantly increased brain oxygenation in one third of brain injured patients, especially when tissue hypoxia was present at baseline. Future studies should highlight the role of inotropic agents in the management of tissue hypoxia in this setting.

Risk of COVID-19 Infection and of Severe Complications Among People With Epilepsy: A Nationwide Cohort Study.

The goal of this work was to evaluate whether patients with epilepsy were more susceptible to coronavirus disease 2019 (COVID-19) infection and at greater risk of severe complications when infected with COVID-19 compared with patients without epilepsy. We included participants who underwent at least 1 severe acute respiratory syndrome coronavirus 2 real-time reverse-transcription PCR test between January 1 and June 4, 2020, from the Korean nationwide COVID-19 dataset. Epilepsy was defined according to the presence of diagnostic code in health claims data before the COVID-19 diagnosis. To investigate the association between epilepsy and the susceptibility for or severe complications of COVID-19, a 1:6 ratio propensity score matching (PSM) and logistic regression analysis were performed. Severe complications with COVID-19 infection were defined as a composite of the incidence of mechanical ventilation, intensive care unit admission, and death within 2 months after COVID-19 diagnosis. Among 212,678 study participants who underwent a COVID-19 test, 3,919 (1.8%) had a history of epilepsy. After PSM, there was no significant difference in COVID-19 PCR positivity according to epilepsy history (odds ratio [OR] 0.86, 95% CI 0.67-1.11). Of the 7,713 individuals with confirmed COVID-19 infection, 72 (0.9%) had a history of epilepsy. Among the patients with COVID-19, severe complications occurred in 444 (5.8%) individuals. After PSM, the presence of epilepsy was associated with the occurrence of severe complications after COVID-19 infection (OR 2.05, 95% CI 1.04-4.04). Mortality after COVID-19 infection did not differ according to the presence of epilepsy history (OR 1.55, 95% CI 0.65-3.70). The presence of epilepsy was not associated with increased susceptibility to COVID-19 infection or mortality related to the infection. However, there was an increased risk of severe complications with COVID-19 in patients with epilepsy; therefore, careful management and monitoring may be necessary.
