An Evaluation of the Usefulness of Selected Screening Methods in Assessing the Risk of Malnutrition in Patients with Inflammatory Bowel Disease.

The aim of this study was to assess the prevalence of malnutrition risk in patients with IBD using different scales to evaluate their usefulness as first-step screening tools for the diagnosis of malnutrition using the GLIM criteria in patients with inflammatory bowel disease. This study included 82 patients with IBD. The Mini Nutritional Assessment, Malnutrition Universal Screening Tool, Saskatchewan IBD-Nutrition Risk and Malnutrition Screening Tool were used to assess malnutrition risk in the study group. In order to diagnose malnutrition, the GLIM criteria were used. According to the GLIM recommendations, malnutrition was diagnosed in 60 patients with IBD (73.17%). Depending on the applied screening tools, the prevalence of moderate and/or high-risk malnutrition in patients with IBD ranged from 20.25% to 43.59%. The highest level of accuracy (ACC) was noted for the MST and MUST questionnaires (92.50% and 90%, respectively), followed by the SASKIBD-NR test (89.97%) and the MNA questionnaire (83.33%). The results of our study indicate a high prevalence of malnutrition in patients with IBD. Thus, there is a need to conduct routine assessments of malnutrition risk using validated scales. The MUST scale seems promising in the assessment of malnutrition risk in patients with IBD as a first step in the assessment of malnutrition using the GLIM criteria.

Indirect and Direct 65+ Patient Reporting of Non-Steroidal Anti-Inflammatory Drug-Induced Adverse Drug Reactions as a Source of Information on Polypharmacy and Polypharmacy-Related Risk.

Background and Objectives: Non-steroidal anti-inflammatory drugs (NSAIDs), which have anti-inflammatory and analgesic properties, are commonly used in the treatment of various, particularly frequent, as well as chronic, conditions in older patients. Due to common polypragmasia in these patients and a high risk of adverse drug reactions (ADRs) and drug interactions, pain management poses a therapeutic challenge. This study describes the importance of ADR reports in the identification of polypharmacy and the ensuing interactions. Materials and Methods: Both healthcare professionals (HPs) and non-healthcare professionals (non-HPs) reports collected in the EudraVigilance database of NSAIDs, including most commonly co-reported medications and reported reactions, were analysed and differences between HPs and non-HPs reports were identified. Results: In the analysed period and group, non-HPs reported more reactions but indicated fewer drugs as suspect or concomitant. The outcomes of our analysis indicate more HP engagement and more detailed reports of serious ADRs when compared to non-serious individual case safety reports (ICSRs) by non-HPs, which appeared more detailed. Such reactions as kidney failure and increased risk of bleeding are known adverse reactions to NSAIDs and common symptoms of their interactions, which were described in the available literature. They were much more frequently reported by HPs than by non-HPs. Non-HPs more frequently reported reactions that may have been considered less significant by HPs. Conclusions: The differences between healthcare professionals' (HPs) and non-healthcare professionals' (non-HPs) reports may result from the fact that the reports from patients and their caregivers require a professional medical diagnosis based on symptoms described by the patient or additional diagnostic tests. This means that when appropriately classified, medically verified, and statistically analysed, the data may provide new evidence for the risks of medication use or drug interactions.

Evaluation of Albumin, Transferrin and Transthyretin in Inflammatory Bowel Disease Patients as Disease Activity and Nutritional Status Biomarkers.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is often accompanied by malnutrition that manifests itself as nutrient deficiencies and body mass loss or deficit. The purpose of this study is to evaluate the utility of albumin, transferrin and transthyretin levels in the assessment of nutritional status and IBD activity. The case-control study included 82 IBD patients. The serum concentrations of albumin, transferrin and transthyretine were determined by a quantitative sandwich enzyme-linked immunosorbent assay (ELISA). Significantly lower median concentrations of albumin were found in the IBD patients vs. controls and in CD patients compared to the UC patients. Significantly higher median transthyretin concentrations were found in the IBD patients compared to the healthy subjects. There were no significant differences in median transferrin concentrations between the IBD patients and the healthy subjects. Significantly higher albumin levels were found in IBD patients in remission compared to patients with moderate and severe exacerbation of IBD symptoms. There were no significant differences in the median transferrin or transthyretin levels in patients with IBD depending on disease activity. No differences were identified in the median transferrin or transthyretin levels in the IBD patients according to nutritional status. The median albumin concentrations in the IBD subjects were significantly higher in patients with normal body fat, normal BMI and normal waist circumferences compared to those with an abnormal nutritional status. The albumin levels reflect both nutritional status and disease activity and therefore cannot be considered a prognostic marker of malnutrition in IBD. As regards the utility of transferrin and transthyretin as markers of activity and nutritional status in IBD patients, further studies are required.

Clostridioides difficile Infections among Pediatric Patients Hospitalized at an Oncology Department of a Tertiary Hospital in Poland.

Background and Objectives: Gastrointestinal tract infections caused by Clostridioides difficile bacteria are diagnosed in pediatric patients with increasing frequency. Children treated at pediatric units are a group of patients at high risk of this infection; therefore, appropriate differential diagnostics and an individual approach to every case are of particular importance. The goal of the study was to assess the clinical parameters of patients with a confirmed CD infection and colonization. Materials and Methods: Every positive case was subjected to a retrospective analysis based on medical history and an infection notification note. Results: Positive results were obtained for 30 patients, among whom the results of 18 patients were considered to justify the diagnosis of an infection. In the remaining patients, treatment was not initiated in only three cases. Cases were detected where treatment was initiated despite the lack of sufficient clinical evidence. Conclusions: This study demonstrates that there are many factors that result in a high risk of the occurrence of CDI in oncology patients, such as antibiotic therapy, multiple hospitalizations, and myelosuppression.

The Hospital Environment as a Potential Source for Clostridioides difficile Transmission Based on Spore Detection Surveys Conducted at Paediatric Oncology and Gastroenterology Units.

Clostridioides difficile is an anaerobic, Gram-positive bacterium widely present in the hospital environment due to its ability to generate spores. The transfer of spores to patients through the hands of medical personnel is one of the most frequent paths of C. difficile transmission. In paediatric patients burdened with a serious primary illness requiring long-term hospitalisation and antibiotic therapy, C. difficile may be a significant risk factor for antibiotic-associated diarrhoea. The goal of the study was to assess the state of hospital environments as a potential source of C. difficile spores and to establish the share of hyperepidemic strains at the two paediatric units. The survey for C. difficile was conducted with a C. diff Banana BrothTM medium, used to detect spores and to recover vegetative forms of the bacteria. Environmental samples (n = 86) and swabs from the clothing of medical personnel (n = 14) were collected at two units of a paediatric hospital, where the cases of antibiotic-associated diarrhoea with a C. difficile aetiology constitute a significant clinical problem. In 17 samples, a change in the broth's colour was observed, indicating the presence of spores. Out of seven samples, C. difficile strains were cultured. The pathogenic isolates of C. difficile were obtained from swabs collected from elements of beds, a toilet, a door handle and a doctor's uniform. In our study, we indicated points of increased risk of pathogen transmission, which could constitute a source of infection. The clothing of medical personnel may be a dangerous carrier of pathogenic spores. Periodical surveys of hospital environments with the use of specialist microbiological mediums successfully indicate the direction of corrective actions to be undertaken by the medical facility in order to increase patient safety.

Dietary Interventions in Inflammatory Bowel Disease.

Inflammatory bowel disease, which primarily includes ulcerative colitis and Crohn's disease, is a group of chronic diseases of the gastrointestinal tract. Mainly affecting young people, it is characterized by periods of exacerbation and remission. In recent years, there has been an increase in the prevalence of inflammatory bowel disease worldwide, including Poland. The potential impact of nutrition and selected dietary components that are directly or indirectly involved in the pathogenesis of intestinal lesions in IBD is not fully clear. Evaluating the impact of diet on the course of IBD is very complex due to the fact that regardless of a dietary model adopted, each one is based on consumption of many different food groups which affect one another. However, the growing need to produce dietary recommendations for these patients has prompted the International Organization for the Study of Inflammatory Bowel Disease (IOIBD) to develop nutrition guidelines for the patients. The present paper characterizes the dietary models most commonly discussed in research studies and their potential impact on IBD activity.

Relationship between Dietary Behaviors and Physical Activity and the Components of Metabolic Syndrome: A Case-Control Study.

Poor diet and low physical activity play an important role in the etiopathogenesis of metabolic syndrome. The aim of this study was to analyze the association between nutrient intake, groups of food products and physical exercise undertaken and the components of metabolic syndrome (MS). The study included 330 patients with MS, and the control group comprised of 270 subjects without MS. The food intake was assessed using 24-h dietary recall, and a 13-item Food Frequency Questionnaire. To assess nutrition knowledge, a Beliefs and Eating Habits Questionnaire was used. The level of physical activity was assessed using the International Physical Activity Questionnaire. Three patterns of behavior were identified: Prudent-Active, Western-Sedentary, and NotPrudent-notWestern-lowActive. In the Prudent-Active group, as compared to the NotPrudent-notWestern-lowActive subjects, the risk of central obesity, hypertension, hypertriglyceridemia, low HDL cholesterol and hyperglycemia occurrence was lower. There was also a lower proportion of patients with MS. As compared to the NotPrudent-notWestern-lowActive subjects, in the Prudent-Active group there was more than a two times higher chance of subjects with a high level of nutrition knowledge. Western diets have been proven to exert a detrimental effect on the components of MS. When designing intervention programs, education of patients with MS on dietary habits and physical activity should be considered.

Vitamin D status in Polish women with endocrine and osteoporotic disorders in relation to diet, supplement use and exposure to ultraviolet radiation.

BACKGROUND: In Europe, the rate of 25(OH)D deficiency is considered high. Thus, it seems necessary to conduct population-based studies to fully assess vitamin D deficiency in various groups of patients. OBJECTIVES: To evaluate serum 25(OH)D levels and the frequency of deficiency in women in Poland with endocrine and osteoporotic disorders. The influences of diet, use of vitamin/mineral supplementation and exposure to ultraviolet (UVB) radiation on vitamin D status in women with metabolic disorders were also examined. MATERIAL AND METHODS: The patient group consisted of 223 women aged 19-81 years diagnosed with endocrine and/or osteoporotic disorders. The control group consisted of 108 clinically healthy women aged 26-72 years. Serum 25(OH)D concentration was assessed using a chemiluminescent immunoassay (CLIA). An ad hoc questionnaire was used to assess the participants' exposure to UVB radiation. Food intake was assessed using a three-day 24-hour questionnaire interview. RESULTS: The following groups showed significantly higher 25(OH)D levels: women taking vitamin D supplements compared to women not taking vitamin D supplements (29.3 ±3.2 compared to 19.5 ±3.7 ng/mL, p = 0.0024); premenopausal women compared to postmenopausal women (28.9 ±5.2 compared to 21.5 ±4.5 ng/mL, p = 0.0021); women who visited sunny countries in the last 6 months compared to women who did not (28.1 ±3.1 ng/mL compared to 24.5 ±5.3 ng/mL, p = 0.0031); and normal weight or overweight women (according to body mass index (BMI)) compared to obese women (27.4 ±4.5 ng/mL compared to 22.3 ±4.7 ng/mL, p = 0.0431). In addition, 25(OH)D concentration correlated with total dietary vitamin D intake in the patient group (R = 0.17, p = 0.0021). Of all examined food groups, fish consumption affected serum 25(OH)D levels in patients (R = 0.20, p = 0.0421) and controls (R = 0.29, p = 0.0002). Consumption of fish products contributed to statistical differences between the patient group (R = 0.17, p = 0.0072) and healthy subjects (R = 0.19, p = 0.0032). CONCLUSIONS: The most crucial factors influencing vitamin D status in the studied women were regular fish consumption, spending holidays in sunny destinations and regular intake of vitamin D preparations.

Assessment of cardiovascular risk in patients with metabolic syndrome working in the agricultural sector.

INTRODUCTION: Cardiovascular diseases are the main death cause in Poland. Several clinical studies showed association between metabolic syndrome and higher prevalence of diabetes mellitus, cardiac events and mortality. The aim of the study was to estimate cardiovascular complications and death risk in subjects with metabolic syndrome (MS) working in agriculture. MATERIAL AND METHODS: The study included 332 people working in agriculture in Lodz voivodeship, 231 with MS and 101 healthy ones. Increased risk of cardiovascular complications was determined for pulse pressure (pp) >63 mmHg. Based on the SCORE index, 10-year death risk due to cardiovascular complications was estimated taking into account sex, age, smoking, systolic blood pressure and total cholesterol concentration. A value ≥5% was accepted as high risk of death within 10 years. RESULTS: Increased risk of cardiovascular complications (pulse pressure >63 mmHg) was found in 31.60% subjects with MS and 6.93% healthy ones. CONCLUSIONS: High risk of cardiovascular complications and death occurs statistically more frequently in subjects with MS than in the rest of the population.

[Surgery first as an alternative approach in patients treated for dentofacial deformities]. / Chirurgia jako pierwsza ­ alternatywne podejscie do leczenia chirurgiczno-ortodontycznego pacjentów z wadami zgryzowotwarzowymi.

Recently surgery first became more popular alternative for treatment of dentofacial deformities. In this approach treatment starts from orthognathic surgery. Immediately after othognathic surgery facial aesthetics and oral function are improved. Thus main complaints of the orthognathic patients are resolved early during treatment period. Indications for surgery first approach are wider than years ago and include: skeletal Class II and III malocclusion, skeletal open bite, bimaxillary protrusion, even cases with severe facial asymmetry are reported. The key point for gaining stable results and total treatment time shortening is an appropriate surgical occlusion. For higher precision of treatment 3D virtual planning is recommended. Total treatment time depends on: number of contact points in surgical occlusion, number of extracted teeth and postsurgical midline deviation. Surgery first is a good alternative approach in some patients treated for dentofacial deformities. Stability in this approach is similar to conventional method of treatment and both methods result in quality of life improvement. As there is lack of presurgical orthodontics in surgery first approach patients avoid transient deterioration in facial aesthetics and oral function that results in higher satisfaction and shorter total treatment time.

[An assessment of the antioxidant vitamins concentration in people with metabolic syndrome working in agriculture]. / Ocena stezenia witamin antyoksydacyjnych u osób z zespolem metabolicznym pracujacych w rolnictwie.

BACKGROUND: Vitamins A, C and E are important parts of the antioxidant barrier. Polish data on antioxidant vitamins deficiency in the population are rare, especially among physically active people with metabolic disorders. The aim of this study was to evaluate the serum concentrations of vitamins A, C and E in people with metabolic syndrome (MS) working in agriculture, the prevalence of their deficiency in these workers, and the correlation between antioxidant vitamins concentration and traditional biomarkers of cardiovascular diseases. MATERIAL AND METHODS: The study included 332 residents of the Lódz Voivodeship working in agriculture: 231 people with MS and 101 healthy ones. The serum concentrations of vitamins A, C and E were assessed using the chemiluminescent immunoassay technology. The antioxidant vitamins intake was assessed by means of a 24-h recall questionnaire using Diet 5.0 software. RESULTS: The mean serum concentrations of vitamins A, C and E were significantly lower in the MS workers than in the healthy ones No correlation was found between the antioxidant vitamins concentration and the dietary intake but there was a correlation between the antioxidant vitamins concentration and high-density lipoprotein cholesterol (HDL-C). A correlation was found between the serum concentrations of vitamins A and C, and vitamins A and E, in the MS workers. CONCLUSIONS: The serum concentrations of antioxidant vitamins in the MS workers were significantly lower than in the healthy controls, despite the similar physical activity level. The dietary intake had no impact on the serum concentrations of these vitamins. The HDL-C concentration in the MS workers correlated with the concentrations of all antioxidant vitamins.

Gender, age, social disadvantage and quitting smoking in Argentina and Uruguay.

INTRODUCTION: Cessation of tobacco use has the potential to provide the greatest immediate benefits for tobacco control. Understanding the social determinants of smoking cessation is an essential requirement for increasing smoking cessation at the population level. The purpose of this study was to analyze the socio-economic dimensions associated with cessation success among adults in Argentina and Uruguay. MATERIAL AND METHODS: Data from the Global Adult Tobacco Survey (GATS), a cross-sectional, population-based, nationally representative survey conducted in Argentina (n=5,383) and Uruguay (n=4,833) was utilized. Univariable and multivariable logistic regression analyses with results being presented as odds ratios (OR) with 95% confidence intervals were applied to study differences among those respondents who sustained smoking abstinence (≥1 year) and those who continued smoking. RESULTS: The GATS study revealed that social gradients in tobacco quitting exist in Argentina and Uruguay. Being aged 25-34, particularly men in Uruguay, women in Argentina, low educated men in Argentina and having a lower asset index were associated with reduced odds for quitting. CONCLUSIONS: Factors that are driving differences in smoking cessation between diverse social groups in Latin America countries need to be considered when implementing relevant interventions to ensure tobacco control strategies work effectively for all population segments.

Lower Plasma Levels of Antioxidant Vitamins in Patients with Metabolic Syndrome: A Case Control Study.

BACKGROUND: Metabolic syndrome (MS) is a coexistence of metabolic risk factors affecting the development of cardiovascular diseases. Reactive oxygen species, which are excessively produced in MS, participate in its pathogenesis. Vitamins A, C and E are an important part of the non-enzymatic antioxidative barrier in humans. OBJECTIVES: The aim of the study was to estimate plasma vitamin A, C and E levels and the intake of these vitamins from the diet in patients with MS. MATERIAL AND METHODS: The study included 182 patients with MS, 94 men and 88 women, aged 30-65 years (mean 57.31 ± 8.28 years). The control group was comprised of 91 subjects, 56 men and 35 women, aged 41-65 years (mean 57.75 ± 5.84 years). The MS diagnosis was based on IDF criteria. The determination of the serum level of vitamin A, C and E was performed using the spectrophotometric method. The food intake was assessed by 24-h dietary recall. RESULTS: The mean plasma vitamin A, C and E levels were significantly lower in MS patients than in the controls (p = 0.05). No correlation was found between vitamin A, C and E intake from the diet and their plasma concentrations in MS patients. Plasma vitamin A, C and E deficiency was observed significantly more often in MS patients than in the control group (15.38% vs. 2.19%, 79.12% vs. 8.79% and 60.45% vs. 5.49%, p < 0.0001, respectively). BMI was the one factor significantly affecting the mean value of vitamin A, C and E levels in MS patients. CONCLUSIONS: MS patients demonstrated significantly lower plasma levels of vitamin A, C and E compared to the healthy subjects. Lower plasma levels of antioxidant vitamins with their high intake from the diet indicate antioxidant barrier impairment in MS patients.

[Evaluation of prevalece of plasma 25(OH)D vitamin deficiency in residents of Lodz]. / Ocena czestosci wystepowania niedoborów witaminy 25(OH)D w osoczu mieszkanców Lodzi.

UNLABELLED: Only scarce data have been published regarding serum vitamin D status in adult population in Poland. Observational studies have suggested relationship between 25(OH)D deficiency and many diseases, such as cardiovascular diseases, autoimmunological diseases or cancers. Still little is known about plasma 25(OH)D deficiency in Polish healthy adults. THE AIM: The aim of the study was to assess plasma 25(OH)D vitamin deficiency in residents of Lodz. MATERIALS AND METHODS: The study included 326 residents of Lodz, 156 men and 170 women, aged 30-65 years (mean 57,25±8,24 years). The study group was divided according to the age and season. The plasma level of 25(OH)D above 30 ng/ml was considered normal, between 21 ng/ml and 30 ng/ml - suboptimal (hypovitaminosis) and below 20 ng/ml - insufficient (deficiency). RESULTS: Plasma 25(OH)D vitamin deficiency was observed in 23,01% participants, hipovitaminosis - in 46,32%, the recommended 25(OH)D concentration in the plasma was observed only in 30,67%. Plasma 25(OH)D vitamin deficiency was observed more often in men than women (25,64% vs. 20,59%, p<0,05);the highest percentage of patients with recommended 25(OH)D vitamin level was observed during summer months (60%). CONCLUSIONS: Plasma 25(OH)D vitamin deficiency was very high in residents of Lodz, especially in men, people over 55 years and during winter months.

Should antioxidant vitamin supplementation be applied in patients with metabolic syndrome? A case-control study.

INTRODUCTION: All cells in the human body are exposed to reactive oxygen species (ROS), which disturb the metabolic reactions in the organism. The antioxidant system in the human body consists of enzymatic and non-enzymatic mechanisms, among which vitamins A, C, and E play a major role. THE AIM OF THE STUDY: The aim of the study was to evaluate the supply of vitamins A, C, and E from daily food rations (DFR) in postmenopausal women with metabolic syndrome (MS) in relation to current nutrition standards. MATERIAL AND METHODS: The study involved 184 women with MS, aged 45-68 years (mean 57.38 ±8.17 years). The control group comprised 90 women, aged 41-65 years (mean 57.48 ±5.79 years) without MS. The food intake was assessed using 24-hour dietary recalls. RESULTS: The evaluation of intake of vitamins measured with daily food rations (DFR) demonstrated that the optimal level of 90-110% according to standards was achieved only in 3.62% of women with metabolic syndrome for vitamin A, in 8.88% for vitamin C, and in 11.41% for vitamin E, which was significantly less often found than in the control group (p < 0.001). CONCLUSIONS: Women with MS are characterised by diversified intake of vitamins A, C and E, and a subgroup of this patients present low level of antioxidant vitamins intake. Supplementation with antioxidant vitamins should be prescribed individually to postmenopausal women with MS.

Occupational exposure and health problems among Polish denturists: a population-based study in Lódz province.

OBJECTIVE: The aim of this study was to analyse the potential health effects of occupational exposure of denturists in the Lódz province. METHODS: The survey was performed among 103 denturists working in 24 dental laboratories in the Lódz province using the questionnaire prepared by the authors. RESULTS: The most common health problems associated with work (occurring daily or at least once a week) were: back pain (69.8%); chronic fatigue syndrome (61.6%); irritation, itching and rashes on the hands (51.2%); restlessness and aggression (43.0%); and watery and itchy eyes (41.9%). Psychosocial and ergonomic hazards associated with work organisation (72.2%) were the most common work environment factors related to the denturist profession. CONCLUSIONS: Analyses of denturists' occupational exposure in the Lódz province and epidemiological estimates of the health effects suggest the need for preventive measures.

[Physical activity in patients with symptoms of metabolic syndrome reduces the concentration of plasma antioxidant vitamins - protective effect of vitamin C]. / Aktywnosc fizyczna u chorych z objawami zespolu metabolicznego zmniejsza stezenia witamin antyoksydacyjnych w osoczu - ochronny efekt witaminy C.

UNLABELLED: Patients with cardiovascular diseases, including those with the symptoms of metabolic syndrome (MS), are recommended regular exercise but many studies indicate its role in the production of reactive oxygen species. Vitamin C supplementation may enhance the antioxidant barrier in MS patients. AIM: The aim of the study was to assess the impact of regular physical activity (PA)and vitamin C supplementation on plasma vitamin A, C and E levels in patients with MS. MATERIALS AND METHODS: The study included 62 patients with MS according to International Diabetes Federation criteria, 32 men and 30 women, aged 38-57 years (mean age 51,24 ± 5,29 years). The patients were divided in two groups: group I (MS+PA) - 31 patients with recommended regular physical activity; group II ( MS+PA+C) - 31 patients with recommended regular physical activity and vitamin C supplementation per os. The control group consisted of 23 healthy individuals without MS, 17 men and 6 women, aged 49-56 years (mean age 53,21 ± 3,6 years), who were not recommended any vitamin supplementation nor physical activity. Plasma vitamin A, C and E levels were estimated in MS patients with spectrophotometry using T60V spectrophotometer (PG Instruments) before and after regular exercise with and without vitamin C supplementation. In the control group plasma levels of antioxidant vitamins were assessed only once. RESULTS: The plasma vitamin A, C and E levels were significantly lower (p<0,05) in MS patients than in the control group. After 6 weeks of regular physical activity a significant fall in plasma levels of antioxidant vitamins was observed in MS patients. In the group of patients with regular physical activity and vitamin C supplementation there was detected a significant rise in the level of all the tested vitamins close to the levels in control group. CONCLUSIONS: Regular physical activity enhances the decrease in plasma antioxidant vitamin level in patients with MS. Vitamin C supplementation conducted in parallel with regular physical activity normalize plasma vitamin A, C and E levels in these patients.

A comparison of performance of endotracheal intubation using the Levitan FPS optical stylet or Lary-Flex videolaryngoscope in morbidly obese patients.

INTRODUCTION: The use of videolaryngoscopes is recommended for morbidly obese patients. The aim of the study was to evaluate the Levitan FPS optical stylet (Levitan) vs Lafy-Flex videolaryngoscope (Lary-Flex) in a group of MO patients. METHODS: Seventy-nine MO (BMI > 40 kg m(-2)) patients scheduled for bariatric surgery were included in the study and randomly allocated to the Levitan FPS or Lary-Flex group. The primary endpoint was time to intubation and evaluation laryngoscopic of glottic view. Anesthesiologists were asked to evaluate the glottic view first under direct laryngoscopy using the videolaryngoscope as a standard laryngoscope (monitor display was excluded from use) and then using devices. The secondary endpoint was the cardiovascular response to intubation and the participant's evaluation of such devices. RESULTS: The time to intubation was 8.572.66 sec. versus 5.790.2 sec. for Levitan and Lary-Flex, respectively (P < 0.05). In all cases of CL grade >1 under direct laryngoscopy, the study devices improved CL grade to 1. The Levitan FPS produced a greater cardiovascular response than the Lary-Flex videolaryngoscope. CONCLUSION: The Lary-Flex videolaryngoscope and the Levitan FPS optical stylet improve the laryngeal visualization in morbidly obese patients, allowing for fast endotracheal intubation, but Lary-Flex produces less cardiovascular response to intubation attempt.

Comparison of microaspiration around TaperGuard tube cuffs and standard tracheal tubes in obese patients subjected to surgery under general anesthesia.

UNLABELLED: Tracheal secretion leakage might lead to ventilator-associated pneumonia. Standard tracheal tube cuffs are cylindrical in shape. Bronchial tree aspiration is observed in the presence of leakage past tracheal tube cuffs. The new TaperGuard tracheal tube has a cuff in the shape of a cone, preventing from the development of microtubules and microaspiration. The aim of the study was to compare standard tracheal tube cuffs with TaperGuard tubes, in terms of protection from microaspiration under general anesthesia. MATERIAL AND METHODS: The observational study evaluated incidents of leakage during general anesthesia with intubation and mechanical ventilation in patients with significant obesity. The study group comprised 20 patients with the BMI >40 kg/m2 subjected to elective surgery under general anesthesia with intubation and mechanical ventilation, randomly divided into two subgroups: standard tracheal tube and TaperGuard tube. RESULTS: In 4 of 10 patients with standard tracheal tubes we observed leakage around the cuff. In case of TaperGuard tubes no such leakage was observed. CONCLUSION: TaperGuard tubes protect against microaspirations, while standard tracheal tubes have no such properties.

A comparison of conventional tube and EndoFlex tube for tracheal intubation in patients with a cervical spine immobilisation.

BACKGROUND: The EndoFlex is a new type of tracheal tube with an adjustable distal tip that can be bent without the use of a stylet. The aim of this study was to compare a standard endotracheal tube with the EndoFlex tracheal tube for intubation in patients with simulated cervical spine injury. METHODS: A group of 60 patients without any kind of the cervical spine injury, classified as the ASA physiological scale I or II and qualified for elective surgery procedures were intubated with the use of classical Macintosh laryngoscope, and either a standard endotracheal tube with the intubation stylet in it or EndoFlex tube without stylet. The subjects were randomized into two subgroups. All patients have had the cervical collar placed on their neck for the simulation of intubation procedure in case of the spinal injury. RESULTS: The intubation procedure was performed by 16 anesthetists with different experience (5-19 yrs). Time of intubation with the use of EndoFlex tube was similar to that with a the use of standard endotracheal tube and intubation stylet: Me (median) 19.5 s [IQR (interquatile range) 18-50] vs. Me 20 s [IQR 17-60] respectively (p = 0.9705). No significant additional maneuvers were necessary during intubation with the use of EndoFlex tube in comparison with standard endotracheal tube (70% vs. 56.6%) (p = 0.4220). Subjective assessment of the usability of both tubes revealed that more anesthesiologists found intubations with the use of EndoFlex more demanding than intubation with conventional tracheal tube and intubation stylet. The assessment of usability: very easy 3.3% vs. 20%, easy 83.4% vs. 56.7%, difficult 10% vs. 20% and very difficult 3.3% vs. 3.3% for standard endotracheal tube with stylet and EndoFlex, respectively. CONCLUSION: In conclusion we asses, that the EndoFlex tube does not improve intubation success rate, in fact it requires more maneuvers facilitating intubation and was found to be more difficult to use.
