Transforming Breast Cancer Care and Clinical Outcomes: Local Experience in Yanbu Industrial City, Saudi Arabia

ObjectiveThis study aimed to enhance outcomes for women undergoing breast cancer screening in a low utilization setting by implementing structured improvement cycles. MethodsImprovement cycles were conducted using the Plan-Do-Study-Act (PDSA) methodology. Three cycles were implemented: (1) dedicating a specific day for breast screening and increasing appointment slots; (2) establishing a breast screening clinic with same-day registration; and (3) introducing a breast surgery clinic to expedite biopsy procedures for BI-RADS-4 category cases. ResultsFollowing each improvement cycle, dramatic increases in patient attendance were observed. In 2021, there was a 67.5% rise compared to the previous year, and a 72% increase in 2022 compared to 2021 figures. Patient characteristics revealed that 60% of attendees were new patients, with 53% of cancer and precancerous cases observed in women below 50 years old. Before the third cycle, the estimated diagnosis turnaround time (TAT) showed that only 23% of patients had their biopsy completed within five working days. However, after the third cycle (n = 131), 63.5% of biopsies were done within five working days. ConclusionStructured improvement cycles guided by the PDSA methodology effectively enhanced breast cancer screening outcomes. These cycles led to increased patient attendance, expedited biopsy procedures, and improved access to timely diagnosis. The findings highlight the importance of systematic approaches in optimizing breast cancer screening and improving patient care. MicroAbstractThis study aimed to improve breast cancer screening outcomes using structured Plan-Do-Study-Act (PDSA) cycles. Implementing dedicated screening days, same-day registration, and expedited biopsy procedures. Turnaround improved from 23% to 63.5% within 5 days post-third cycle. PDSA-guided cycles dramatically improved patient attendance, expedited biopsy procedures, and timely diagnosis, optimizing breast cancer screening and patient care.

Determining the role of remote consultations in general surgical practice in Scotland: a qualitative questionnaire-based study

INTRODUCTION Telemedicine consultations became widespread during the COVID-19 pandemic to deliver healthcare while minimising viral transmission. Research around establishing the role of remote appointments in general surgery outpatient clinics after the pandemic has not been undertaken. The aim of this study was to investigate views on remote consultations to determine this. METHODS Patients attending the adult general surgical outpatient clinic at Aberdeen Royal Infirmary between August 2021 and January 2022 as well as general surgeons from three neighbouring hospitals were invited to complete an anonymous questionnaire on the acceptability of remote and face-to-face (F2F) appointments in pre and postoperative scenarios. Differences in patients’ preferences between demographic groups, and between patients’ and surgeons’ views were analysed. RESULTS A total of 51 patients and 26 surgeons responded. Patients’ views differed depending on demographic parameters and the scenario. Patients and surgeons had similar views on preoperative consultations. Given the choice of telephone, video or F2F appointments, the F2F option was overall most popular. Patients and surgeons differed in their views on remote consultations following surgery and acute admissions. In some scenarios, young patients, those who lived in remote regions and those in employment/education preferred remote appointments. CONCLUSIONS While telemedicine is feasible and acceptable in general surgery clinics, there are differences in preferences between surgeons and patients. Patients’ preferences varied depending on their background, home circumstances and clinical context. Service provision should ensure that when remote consultations are available, patient preference is prioritised rather than surgeon ease.

Evaluation of the Relationship Between Bacterial Infection and Immunological Factors with Diabetic Foot Ulcer

Diabetes represent a chronic disorder that involve the decline in the levels of insulin produced by the pancreas due to many genetic and environmental factors. The disease involves the elevation of blood sugar in the circulation which may lead to vascular, neurological, ocular and renal complications. In addition, diabetic patients tend to develop ulceration due to wound infection swiftly in the lower limbs due to the reduce in the neurological sensation as well as to elevated sugar circulation which may greatly provoke wound infection and diabetic foot ulcerations. The current study aimed at isolation of the common causes of bacterial infection associated with diabetic foot ulcer as well as the assessment of IL-17 and IL-18 and in those patients and in control healthy group. The present study was conducted in Salah Aldeen province during the period from 1st of November 2023 to 15th of May 2024 and included 150 patients with diabetic foot infection who attended Salah-Alden Hospitals: (Tikrit Teaching Hospital, Balad General Hospital and private surgery clinics). Swabs and whole blood from patients with diabetic foot ulcer were taken and submitted to routine culture and identification of the causative bacterial infection followed by biochemical identification and antibiotics susceptibility test for the isolated microbe. The serum specimens from those positive bacterial isolates were submitted for IL17 and IL-18 ELISA assessment. IL-17, significant elevation P<0.05 of this cytokine was recorded in diabetic patients with foot ulcer with mean 21.94 pg/ml compared to control group. In the same way significant increase of IL-18 (P<0.05) was noted in diabetic patients with foot ulcer with mean 347.15 pg/ml in comparison to control group. In conclusion, diabetic foot ulceration is the result of in controlled elevation of blood glucose and bacterial infection with various pathogens can complicate the scenario, and the significant elevation of IL17 and IL18 in those patients can insight the role played by these cytokines in signaling the immune to recruit cellular and humoral response.

Determination of Comfort Levels and Spiritual Care Needs of Gynecologic Cancer Patients with Abdominal Drains: A Cross-Sectional Descriptive Study in Turkey.

This study was conducted to determine the comfort levels and spiritual care needs of gynecologic cancer patients with abdominal drains. The study was conducted with 61 gynecologic cancer patients with abdominal drains at the gynecologic oncology surgery clinic of a state hospital in Turkey. Data were collected using the "Participant Information Form," "Perianesthesia Comfort Questionnaire (PCQ)", and "Spiritual Care Needs Inventory". Kolmogorov-Smirnov test and Mann-Whitney U test were used to analyze the data. It was found that the postoperative comfort of the patients in this study was above a moderate level. Patients who did not need spiritual care, did not fulfil religious rituals regularly and did not receive social support had a high level of comfort in the early postoperative period. Patients with gynecologic cancer were found to have high spiritual care needs. Patients without chronic diseases, possessing a single abdominal drain, familiar with the concept of spiritual care, expressing a need for spiritual care, engaging in regular religious rituals, and enjoying social support were identified as having elevated spiritual care needs. Within the framework of holistic nursing care provided to gynecologic cancer patients with abdominal drains, the results reveal the necessity of spiritual care and the importance of comfort.

Association between Type D personality, illness perception, and coping strategies in patients undergoing open-heart surgery.

A combination of social inhibition and negative affectivity characterizes Type D personality. Type D, or distressed personality, is an established risk factor for the development and prognosis of coronary heart disease. It occurs in approximately 1 in 4 patients with coronary heart disease. This study aimed to investigate the relationship between Type D personality, illness perception, and coping strategies in patients undergoing open-heart surgery. This retrospective and cross-sectional study was conducted in a university hospital psychiatry and cardiovascular surgery clinics between February 2022 and April 2022. Seventy-one volunteered patients over the age of 18 who underwent open-heart surgery in the cardiovascular surgery clinic were included in the study. Cardiovascular surgeons recorded the sociodemographic and clinical data of the patients and referred them to the psychiatry clinic for further evaluation. Subsequently, patients underwent psychiatric evaluation and were assessed using the Type D Personality Scale, Coping Attitudes Assessment Scale, Hospital Anxiety and Depression Scale, and Illness Perception Questionnaire. According to this study, individuals with Type D personality tended to have higher scores on the Hospital Anxiety and Depression Scale. Analysis of the subdimensions of the Stress Coping Styles Scale revealed that individuals with Type D personalities showed a significantly lower optimistic approach and a considerably higher helpless approach. In terms of the subdimensions of the Illness Perception Questionnaire, it was found that individuals with Type D personality had a statistically lower treatment control approach and a statistically higher emotional representations approach. Identifying Type D personality traits in patients undergoing open-heart surgery can help manage negative illness perceptions through effective coping mechanisms.

Paradoxical bodies: negotiating biomedical fix, responsibility, and care in a weight-loss surgery clinic

AbstractThis ethnographic project explores how inherent discursive and social tensions are expressed and worked out within obesity care at a weight-loss surgical (WLS) clinic. First, complicated doctor and patient encounters occur because WLS follows a medical logic of intervention and is presented as a “biomagical” procedure that miraculously alters the body. Surgeons, however, explain that the surgery’s success depends on patients’ long and hard work. Second, the clinic’s interdisciplinary approach adds more complexity. While expanding the scope of treatment, it blurs the division of labor among professionals and the distinction between body and mind. It also diffuses the responsibility for patients’ lifestyles and recovery among professionals. Third, alongside notions about patients’ autonomy and free choice, their wishes and bodies are constantly channeled, problematized, and negotiated with various family and peer support. While crucial for the surgery’s success, such interconnectedness raises questions about how decision making and social pressures affect the patients’ journey. Thus, WLS is refracted among webs of multiple actors and contradictory perspectives. This complexity invites a reflection on how such tensions and paradoxes destabilize medical power in modifying the body, challenge personal responsibility assumptions, and impact the quality of care.

Utility of the Neutrophil to Lymphocyte Ratio for Predicting Mortality in Pleural Empyema - A Retrospective Study

Purpose: The prognostic qualities of the hematological biomarker neutrophil to lymphocyte ratio (NLR) have not yet been evaluated in pleural empyema. Therefore, we aimed to find if NLR can predict adverse outcome in such clinical setting. Methods: Retrospectively we studied 84 patients with pleural empyema who were operated in emergency setting in a clinic of thoracic surgery of an academic hospital over a 34-month period (01.2021- 10.2023). To assess the prognostic performance of NLR we used the area under the receiver operating characteristics (AUROC) curves. Results: Of a total of 84 patients, nine (10.7%) died. Using ROC Curve analysis we found that NLR has an excellent prognostic ability and outperformed systemic immune inflammation index (SII), platelet to lymphocyte ratio (PLR), quick- sequential organ failure (qSOFA) score and systemic inflammation response syndrome (SIRS) (AUROC = 0.904 vs 0.782 vs 0.749 vs 0.747 vs 0.676, respectively) in outcome prediction. An optimal threshold NLR > 9.88 x 109 /L for prognostication of death was identified with a sensitivity of 85.7% and a specificity of 83.6%. Conclusion: In pleural empyema the neutrophil to lymphocyte ratio demonstrates excellent ability to predict the unfavorable outcome.

Sedated beauty: The invisible knife in online narratives about cosmetic breast augmentation.

Breast augmentation is a prevalent cosmetic surgery procedure among women in Western societies, and the cosmetic surgery market has witnessed substantial growth. Today, websites and online forums are platforms that feature discussions about cosmetic procedures. A genre on surgery clinic websites is 'patient stories', but also lay-initiated internet forums facilitate discussions and shared experiences related to cosmetic surgery. This study aims to analyse lay-initiated online narratives about cosmetic breast augmentation. The shared narratives contain descriptions of how women who are about to undergo breast augmentation prepare for surgery, the medical procedures that take place on the day of surgery itself, and the experiences and feelings after waking up after anaesthesia. Employing a structural analysis of 30 of these stories, this research illuminates how the surgery stories adhere to a conventional storytelling format, and how key characters within the stories are 'helpers and makers', including relatives, nurses and surgeons. The focus in these narratives revolves around the woman herself, although her active involvement is primarily observed during the preparation phase, with a more passive role assumed during subsequent clinic routines. Despite instances of pain and discomfort in the narratives, the stories are enveloped in an aura of glamour and a spa-like atmosphere. It is discussed how this 'fairy tale' story, narrating a surgical metamorphosis, seems to align with the popularisation of the cosmetic surgery sector.

Incidence and Prognostic Significance of Silent Coronary Disease in Asymptomatic Patients with Severe Aortic Stenosis.

Background and Objectives: The aim of this study was to estimate the prevalence of silent coronary artery disease (CAD) in asymptomatic patients with severe aortic stenosis (AS) and assess long-term prognosis in terms of major adverse cardiovascular event (MACE)-free survival. Materials and Methods: This was a prospective study conducted at the Clinic for Cardiac Surgery, University Clinical Center of Serbia, in asymptomatic patients with severe AS, normal LVEF and stress test without signs of myocardial ischemia. Adverse cardiovascular events (cardiac death, myocardial infarction and any hospitalization due to heart disease) was monitored during one year of follow up. Results: A total of 116 asymptomatic patients with severe AS were included in the study. The average age was 67.3 ± 9.6 years, and 56.9% of patients were men. The most common cause of AS was degenerative valvular disease (83.5%). The incidence of significant CAD was 30 out of 116 patients (25.9%). The median Society for Thoracic Surgeons (STS) predicted risk of mortality score was 1.62% (25th to 75th percentile: 1.15-2.76%). The overall mean gradient across aortic valve (Pmean) was 52.30 mmHg ± 12.16, and the mean indexed AVA (AVAi) was 0.37 ± 0.09 cm2/m2. The mean LVEF was 68.40% ± 8.01%. Early surgery for aortic valve replacement was performed in 55 patients (55.2%), while 52 (44.8%) patients received conservative treatment. Twenty-two patients (42.3%) in the conservative treatment group underwent surgery during follow up. There were a total of 44 (37.9%) patients with MACE during one year of follow up. Univariate Cox regression analyses identified the following significant risk factors for MACE-free survival: presence of CAD and early conservative treatment (p = 0.004), age (p = 0.003), diabetes mellitus (p = 0.016) and STS score (p = 0.039). According to multivariate analysis, the presence of CAD with early conservative treatment was the most important predictor of MACE-free survival in asymptomatic patients with severe aortic stenosis (p ≤ 0.001). Conclusions: Early surgery for aortic valve replacement in asymptomatic patients with severe AS and concomitant CAD is beneficial for long-term survival.

WP5.1 - An audit of Escherichia coli bacteraemia from a hepatobiliary origin

Abstract Aims Gallstone disease is the commonest cause of biliary sepsis, which in turn is a frequent source of Escherichia coli bacteraemia (ECB). In 2022, our health board was an outlier for ECB infection rates. It was hypothesized that this may be related to extended waiting times to be seen at the surgical clinic or rising numbers on the waiting list for cholecystectomy, caused by the COVID-19 backlogs. This study aims to assess the prevalence and characteristics of ECB infections associated with hepatobiliary conditions in a tertiary centre in Scotland, and review any associations with waiting lists. Methods A retrospective analysis of ECB cases linked to hepatobiliary conditions between 01/01/2022 and 31/12/2022 was conducted. Parameters studied included infection acquisition (community, hospital, healthcare-associated), biliary disease history, inpatient/outpatient status, waiting list status, admission specialty and treatment modalities. Results Of the 71 cases analysed, 68% were community-acquired, while only 15% were healthcare or hospital-associated. Non-malignant biliary disease was present in 43% of patients, and 39% had prior inpatient history. The majority were not on clinic (89%) or surgery (92%) waiting lists. General surgery was the commonest admitting speciality (51%). Mortality rate was 17%. Conclusions This audit did not identify an association between increases in ECB rates and waiting lists for clinic review or surgery, and very few patients were awaiting cholecystectomy. The study confirms the clinical significance of hepatobiliary-associated ECB infection, with mortality rates similar to that of previously published reports.

Etiological Differences in Thoracic Traumas After Earthquake

Objective: Since Türkiye has a geography located on fault lines, the possibility of an earthquake occurring in this region will always continue to exist. After an earthquake, a variety of traumas can occur. Thoracic traumas are also injuries frequently experienced in case of earthquakes. Material and Methods: At Kahramanmaraş Sütçü İmam University Thoracic Surgery Clinic, 124 patients were examined, including pre-earthquake and post-earthquake chest trauma. The pre-earthquake group was called Group 1, and the post-earthquake group was called Group 2. Gender, age, type of trauma of the patients as well as the file records of traumas were examined. Results: The frequency of trauma increased in men compared to women. There was a significant increase in hemothorax cases. It was observed that blunt trauma etiology was again the most common cause of trauma, but the etiology of blunt trauma increased in favor of falling from a height. Conclusion: It is planned to eliminate the housing problem in time and intensive work is being carried out in the region on this issue. We believe that with the decrease in the intensity of construction work and the beginning of reverse migration, these changing differences in the etiologies of trauma after the earthquake will return to the pre-earthquake period in time.

Postoperative recovery after suspension suture placement at the site of esophagojejunal anastomosis after total gastrectomy: Comparison of two surgical techniques.

Despite improvements, survival rates for gastric cancer remain low, even in developed countries, confirming the role of primary and secondary prevention. This study aims to demonstrate the role of additional suspension sutures on the esophagojejunal anastomosis (EJA) to strengthen the anastomosis, i.e., relieve the mechanical suture. A retrospective cohort study was conducted from 2011 to 2022 at the Clinic for Surgery, University Clinical Center Tuzla, Bosnia and Herzegovina. The experimental group consisted of patients placed with a suspension suture at the esophagojejunal anastomosis (EJA) site after total gastrectomy. The control group was patients without a suspension suture. The clinical and laboratory parameters available from the medical history were analyzed, X-ray passage, surgical complications, non-surgical complications, the length of hospitalization, the postoperative course, time of onset of postoperative complications, postoperative radiological follow-up and endoscopic postoperative follow-up were then analyzed. A total of 212 patients were included in the study: 87 in the experimental group with suspension sutures on the EJA and 125 in the control group without suspension sutures on the EJA. The two cohorts did not differ in other clinicopathologic parameters except perineural invasion, which was more prevalent in the control group. Patients in both groups were anemic and elevated values of C reactive protein (CRP) and decreased levels of proteins, albumin and globulin, with no significant difference between the two groups. The most common general complication was pleural effusion (28%), followed by pneumonia (∼22%). The most common complication in the experimental group was an intraabdominal abscess, while in the control group, it was a surgical wound infection. Our study did not show a statistically significant difference between the two analyzed EJA techniques created with a circular stapler, when it comes to postoperative course and outcome in patients with gastric cancer.

Mutation Spectrum Comparison between Benign Breast Lesion Cohort, Unselected Cancer Cohort and High-Risk Breast Cancer Cohort.

Mutation study for high-risk breast and ovarian cancer (HBOC) has been extensively studied in patients of different ethnicities. Here we compared the germline mutation rate and mutation spectrum of patients (n = 4341) with benign breast diseases or breast cancers, with and without other risk factors. Three cohorts of Chinese patients were recruited. The first cohort, high-risk cohort (HR, n = 3935) included high-risk breast cancer patients fulfilling high-risk HBOC criteria and who are recruited at our genetics clinic. The second cohort, unselected cancer cohort (CC, n = 307) was from general recruitment of patients with breast cancer at breast surgery clinics. The third cohort, benign breast lesion cohort (NC, n = 99) comprised 99 patients with benign breast diseases such as fibroadenoma, fibroadenomatoid hyperplasia, and intraductal papilloma. Thirty HBOC related genes were sequenced on the above-mentioned patient cohorts. The germline mutation rates of HR, CC, and NC cohort were 11.9%, 6.5%, and 8.1%, respectively. In the CC cohort, 29.3% (90/307) of patients fulfilled the National Comprehensive Cancer Network (NCCN) high-risk genetic test criteria 2022 v.2. The mutation rate for this group of patients was 11.1%, similar to that of the HR cohort, while the mutation rate for those not fulfilling testing criteria was 4.6%, like that of the NC cohort. High penetrance genes (BRCA1/2, CDH1, PALB2, PTEN, and TP53) mutations were only found in the HR (10.6%) and CC (3.3%) cohorts but were not found in the NC cohort. ATM, BRIP1, RAD51C, and RAD51D mutations were identified in all cohorts. RAD51C and RAD51D mutations showed conflicting penetrance. An unexpectedly high mutation rate of total 2% was found in the NC cohort but it was only 0.3% and 0.5% in the HR cohort and CC cohort, respectively. Our results show a clinical need to enhance genetic testing of unselected breast cancer patients to identify the high-risk patients.

Aorto caval fistulas.

The purpose of this paper is to examine and assess the outcomes following open repair in 39 patients who experienced aorto-caval fistula (ACF) resulting from the spontaneous rupture of an abdominal aortic aneurysm (AAA). We reviewed the clinical records of all patients surgically treated with open repair for ACF at the Clinic for Vascular and Endovascular Surgery of the Serbian Clinical Center in Belgrade, Serbia, from January 2012 to February 2023. All of the patients in this series were consecutive and had aorto-caval fistula from AAA. No patients were excluded from the procedure due to the life-threatening nature of the state. A follow-up assessment was performed during the follow-up examination or by telephone interview with the patient or a family member. All patients were male, with mean age 67.4±8.3 years (range: 52-83 years). The 30-day mortality rate in our cohort was 35.9%, with three (7.7%) intraoperative deaths, and 11 deaths in the postoperative period (28.2%). A total of 25 patients out of 39 (64.1%) in the original cohort have survived the surgery and the postoperative period and were followed-up for a total of 67.1 person-years. The mean follow-up was 3.7±2.2 years (range 0.25-8.4 years). Two patients (8.0%) died during the follow-up, 16 patients (64.0%) survived, and seven (28.0%) were lost to follow-up. The long-term mortality rate in the cohort that survived the postoperative period was 3.0/100 person-years. ACF caused by spontaneous AAA rupture into the inferior caval vein or iliac veins is a relatively rare, life-threatening condition which requires prompt treatment. An exact preoperative diagnosis is essential for perioperative strategy. As the comparison of our results with the results from contemporary literature indicates, wherever possible endovascular repair should be considered since it results might be superior to open repair.

PREVALENCE OF OCCULT CERVICAL LYMPH NODES METASTASIS IN CN0 IN ORAL SQUAMOUS CELL CARCINOMA (OSCC)

Occult metastasis is not easily detected clinically or radiographically. Various methods have been applied for neck control for clinically N0 via elective neck dissection (END), wait and watch (W&W) and sentinel lymph node biopsy (SLNB). The main aim of this study is to investigate the prevalence of occult cervical lymph nodes metastasis in cN0 in oral squamous cell carcinoma, to investigate and compare the disease-free state and overall survival rate between occult metastasis and the non-occult group that presented at the oral and maxillofacial surgery clinic, Faculty of Dentistry, Universiti Malaya. This is a retrospective study involving 48 patients with complete data from 2008 to 2019. Data collected includes socio-demographic and clinicopathologic factors. Descriptive analysis was performed and Kaplan-Meier analysis was used to compare disease-free status and overall survival period between occult and non-occult metastases groups. The prevalence of occult metastasis in oral squamous cell carcinoma (OSCC) was low at 8.3% but it became 100% on OSCC tongue. The main tumor site for occult metastasis originated from the oral tongue with T2 size. Non-occult group had better overall survival rate comparing to occult metastasis group and the advanced group. Therefore, END is recommended particularly for N0 OSCC tongue.

PANDANGAN TENTANG PRAKTIK BEDAH PLASTIK DALAM ARTIKEL OPINI DI SURAT KABAR KOREA TAHUN 2010–2019

This research aims to reveal Korean’s perspectives on plastic surgery practices through a corpus-based text analysis of Korean online newspapers. The research used quantitative and qualitative methods to observe keywords, significant collocates, and semantic preference. The data used were 106 opinion articles about plastic surgery in Chosun Ilbo and Donga Ilbo (2010–2019). Keyword analysis shows that the most frequently used keywords are seonghyeong (189 times) and seonghyeongsusul (116 times). Analysis of significant collocates and semantic preferences revealed that plastic surgery was frequently discussed in relation to body parts, people (collocate yeoseong (women), junggukin (Chinese), hwanja (patient), gwangganggek (tourist)), country (collocate jungguk (China), hangguk (Korea)), intensity (gwadohan (excessive)), and effect (phihae (loss)), and others. Plastic surgery clinics are frequently addressed in terms of location (collocate Gangnam, Seoul), intensity (collocate daehyong (big scale)), and others. Based on the findings of this study, plastic surgery is primarily performed on local women and international patients, particularly Chinese tourists. Plastic surgery is also perceived as having a negative impact, being overdone, and causing numerous difficulties. Plastic surgery performed on foreign patients is considered as beneficial to Korean economic progress, but it should not be performed on Koreans.

Association of serum alpha-fetoprotein (AFP) with indirect prognosis in gastric cancer

Aims: Alpha-fetoprotein (AFP) is a glycoprotein secreted from the yolk sac and hepatocytes during fetal life. Elevated levels in adults are considered markers for yolk sac tumors, hepatocellular carcinoma and gastric cancer. There is still no consensus on the definition of AFP-secreting gastric cancers, but AFP-secreting gastric cancers have been reported to have a worse prognosis. In this study, AFP levels in gastric cancers with high AFP were compared with pathology results and evaluated in terms of indirect prognosis. Methods: Patients with gastric cancer operated in the General Surgery Clinic of Ankara Bilkent City Hospital between 2019 and 2023 were retrospectively screened. Among the screened patients, those whose information could not be reached and those with incomplete information were excluded and 126 patients were included in the study. Serum AFP levels of these patients were compared with pathology results, stages and tumor sizes. Results: The mean age of the patients in our study was 66±11 years, 42 (33.6%) were female and 84 (66.7%) were male. Of the 126 patients analyzed in the study, 107 (84.9%) were AFP-negative and 19 (15.1%) were AFP-positive. There was no significant difference in AFP levels between all patients in terms of liver metastasis, peritoneal metastasis, disease stage, perineural invasion and tumor location. However, serum AFP levels were significantly higher in patients with lymphovascular invasion and lung metastases (p=0.042; p=0.024). In the analysis for serum AFP level in the presence of lymphovascular invasion, ROC value was 2.35 ng/ml, sensitivity 58.2%, specificity 55.9%, area under the curve (AUC) 0.618, 95% confidence interval (95% CI) 0.512-0.723 and p=0.028. Conclusion: Lymphovascular invasion is a poor prognostic factor in gastric cancer. In this study, a significant correlation was found between serum AFP value and lymphovascular invasion. In gastric cancers without AFP secretion, a serum AFP value above 2.35 ng/ml may be indirectly associated with poor prognosis because it predicts lymphovascular invasion.

Intermittent hypoxic preconditioning reduces the risk of peri- and postoperative complications during on-pump cardiac surgery

Aim. To assess the effect of intermittent hypoxic-hyperoxic exposures (IHHE) on the outcomes of on-pump cardiac surgery.Material and methods. This prospective, single-center, randomized, controlled study was conducted in 110 patients with heart valve defects and/or aortic pathology from the cardiac surgery clinic of the I. M. Sechenov First Moscow State Medical University. The total sample was randomly divided into a group of patients who underwent IHHE (n=66) and a control group of patients who underwent placebo procedures with ambient air (n=44). The frequency and structure of intra-and postoperative complications were analyzed within 30 days after surgery. The presence of cognitive impairment, as well as serum troponin I and lactate concentrations were analyzed before and after surgery.Results. Peri- and early postoperative complications such as cardiac death, non-fatal infarction and acute heart failure occurred significantly less frequently in patients treated with IHHE compared with placebo group (1,6% vs 16,7%, p=0,009; 1,6% vs 16,7%, p=0,009; 6,3% vs 33,3%, p<0,001, respectively). The median troponin I values 24 hours after surgery were 1,068 ng/ml (0,388-1,397 ng/ml) in the IHHE group and were significantly lower compared to the control group (1,980 ng/ml (1,068-3,239 ng/ml)). The serum lactate level after surgery was 1,8±0,7 mmol/l in the IHHE group and was significantly lower compared to the control group — 2,4±1,2 (p=0,05). Cognitive function, assessed by MOCA and MMSE tests, turned out to be significantly higher in patients who underwent a preoperative IHHE. No significant complications or serious adverse events were observed during the IHHE procedures.Conclusion. The use of individually adapted hypoxic preconditioning procedures reduces the incidence of peri- and postoperative complications, which is accompanied by a lower ischemia-reperfusion myocardial injury during artificial circulation with preservation of cognitive functions. IHHE procedures ramp up prehabilitation of patients referred for on-pump surgery of heart defects and aortic pathology.
