Trace Elements Levels in Major Depressive Disorder-Evaluation of Potential Threats and Possible Therapeutic Approaches.

The multifactorial etiology of major depressive disorder (MDD) includes biological, environmental, genetic, and psychological aspects. Recently, there has been an increasing interest in metallomic studies in psychiatry, aiming to evaluate the role of chosen trace elements in the MDD etiology as well as the progression of symptoms. This narrative review aims to summarize the available literature on the relationship between the concentration of chosen elements in the serum of patients with MDD and the onset and progression of this psychiatric condition. The authors reviewed PubMed, Web of Science, and Scopus databases searching for elements that had been investigated so far and further evaluated them in this paper. Ultimately, 15 elements were evaluated, namely, zinc, magnesium, selenium, iron, copper, aluminium, cadmium, lead, mercury, arsenic, calcium, manganese, chromium, nickel, and phosphorus. The association between metallomic studies and psychiatry has been developing dynamically recently. According to the results of current research, metallomics might act as a potential screening tool for patients with MDD while at the same time providing an assessment of the severity of symptoms. Either deficiencies or excessive amounts of chosen elements might be associated with the progression of depressive symptoms or even the onset of the disease among people predisposed to MDD.

Does the Epstein-Barr Virus Play a Role in the Pathogenesis of Graves' Disease?

Graves' disease (GD) it the most common chronic organ-specific thyroid disorder without a fully recognized etiology. The pathogenesis of the disease accounts for an interaction between genetic, environmental, and immunological factors. The most important environmental factors include viral and bacterial infections. The Epstein-Barr virus (EBV) is one of the most common latent human viruses. Literature has suggested its role in the development of certain allergic and autoimmune diseases. EBV also exhibits oncogenic properties. The aim of the study was to analyze and compare the presence of EBV DNA in peripheral blood mononuclear cells (PBMCs) in patients with newly recognized GD and to find a correlation between EBV infection and the clinical picture of GD. The study included 39 untreated patients with newly diagnosed GD and a control group of 20 healthy volunteers who were gender and age matched. EBV DNA was detected with reverse transcription polymerase chain reaction (RT PCR) assay. The studies showed a significantly higher incidence of EBV copies in PBMCs among GD patients compared to the control group. Whereas, no significant correlations were found between the incidence of EBV copies and the evaluated clinical parameters. Our results suggest a probable role of EBV in GD development. EBV infection does not affect the clinical picture of Graves' disease.

[Breasts self examination - everything we want you to know about it - survey study].

OBJECTIVE: Introduction: Breasts self examination is first line prevention in case of breast cancer. It is cheap, it is easy and it can save your life. That is why it is so important that every woman and even man know how to do it. The aim: To estimate the level of knowledge about breasts self examination among women and also among people connected with medicine. PATIENTS AND METHODS: Materials and methods: The data were gathered through the internet questionnaire, which contained of 14 questions. There were 204 respondents : 53% women and 47% men. Among them there were 93% people related with medicine. Average age was 23,5 years. The participation was voluntary and annonymous. RESULTS: Results: Among female respondents 57% admit doing breasts self examination, however only 23% of them do that regularly every month. Also only 36% of the respondents know how to do proper examination. When asked if they ever had their breasts examined by the doctor, only 20% replied positively. We also prepared questions for people connected with medical field: we asked them if doing breasts examination for the patient they would feel confident (61% replied negatively.) and also if they had a chance to do breasts examination during studies most of them replied negatively. CONCLUSION: Conclusions: To conclude, even among women connected with medical field the knowledge is not enough, which is the most concerning since they should educate others and diagnose concerning symptoms. We should put more afford to break the tabu and pay more attention to breast examination.

Impact of experimental diabetes and chronic hypoxia on rat fetal body weight.

OBJECTIVES: The aim of the study is to determine the impact of the experimental diabetes and the chronic hypoxia on pregnancy development and rat fetal body weight. MATERIAL AND METHODS: The experiment was performed on female Wistar rats. Animals were divided into the experimen-tal groups. I - Controls, II - Untreated diabetes, III - Insulin-treated diabetes, IV - No diabetes with chronic hypoxia, V - Untreated diabetes and chronic hypoxia, VI - Insulin- treated diabetes and chronic hypoxia. Diabetes was induced in groups II, III, V and VI with intraperitoneal injection of streptozocin (STZ) at a dose of 40 mg/kg. Chronic hypoxia was induced by placing dams (groups IV, V and VI) in conditions of 10.5% oxygen and 89.5%. Insulin was administered subcutaneously at the dose of 9 IU/kg. Starting from the 6th day after STZ injection and chronic hypoxia conditions animals were caged together for 12 hours for 3 consecutive days to ensure fertilization. On day 21 of gestation the animals were decapitated, the fetuses were removed and weighted. RESULTS: Mean fetal body weight in separate groups were: I - 5.38 g, II - 6.04g, III - 5.32g, IV- 5.56 g, V - 3.45 g, VI - 6.23 g. CONCLUSIONS: Pre-existing type 1 diabetes does not affect fetal body weight compared to healthy newborn control rats. Pro-longed hypoxia does not impact on fetal body weight. Chronic hypoxia during pregnancy complicated with untreated type 1 diabetes mellitus leads to significant reduction of fetal body weight. Insulin treatment reversed the detrimental effect of chronic hypoxia on fetal development.

[Public knowledge of the infertility and legal aspects of infertility treatment in Poland].

OBJECTIVE: Introduction: The awareness of infertility is limited in Polish society despite the fact that this problem affects around one million couples in our country. Some of them decide to undergo specialistic treatment. Issues pertaining techniques of contributed reproduction are strictly regulated by Polish law. PATIENTS AND METHODS: Material and methods: The study was conducted among the residents of Lublin in the period from October 1, 2017 to May 1, 2018. The research tool was an original, anonymous questionnaire containing 24 questions. The study group consisted of 164 people. Statistical analysis was performed using T-student test for non-parametric variables. RESULTS: Results: The majority of the examined group were people who worked the medical profession (71%). It is significant that as much as 79.3% of respondents are religious. Only 8,5% of respondents know that the Polish law on infertility treatment is regulated in Act on the treatment of infertility of 25 June 2015. Almost half of the respondents (44.2%) answered correctly to the question regarding the treatment of infertility according to the binding Act. Only 28,5% of respondents were able to give the definition of embryo included in the Act. Moreover, almost all respondents (92.1%) never met with lectures about legal aspects in the treatment of infertility. Half of the respondents (47.3%) correctly indicated the most common cause of female infertility, the reason of men infertility was correctly indicated more respondents (65.5%). CONCLUSION: Conclusions: The respondents knowledge of infertility is more extensive than their knowledge of the legal regulations about infertility treatment. Respondents asked about regulations included in the Act on the treatment of infertility of June 25, 2015 mostly did not answer questions or gave wrong answers. The respondents whose field of study was related to medicine gave more correct answers compared to people who study non-medical fields. Practicing Catholic (45%) more often gave wrong answers.

[testicles self examination - knowledge and abilities - survey study].

OBJECTIVE: Introduction: Testicle cancer is a common malignant cancer among young men (20 to 44 years). In 90% of cases we can feel nodule or change of consistency, which means during testicles self examination we can quickly discover cancer. The aim: To estimate the level of knowledge about testicles self examination among men and also medical stuff and students. PATIENTS AND METHODS: Materials and methods: We gathered the data through the internet questionnaire, which contained of 13 questions. There were 204 respondents (53% women and 47% men). 93% were related with medicine. Average age was 23,5 years old. The participation in the study was voluntary and annonymous. RESULTS: Results: Only 41% of our respondents perform self examination. When asked if They every had Their testicles checked by a doctor only 33% responded positively. Most of the respondents almost correctly point out symtpoms and risk factors of testicles cancer. Only 22% of medical related respondents feel confident while performing testicles examination with the patient and just 12% of them had a chance to do it during studies. We also asked our respondents if They have ever seen a social campaign about priopriate testicles self exmiantion and 80% of them respondet negatively. CONCLUSION: Conclusions: The level of education about testicles examination is on low level. Men are usually aware of the risk, but They neglect it. In most cases doctors do not examine testicles and are not confident about it. We have to put more concern to that case.

Bioelectrical impedance phase angle and subjective global assessment in detecting malnutrition among newly diagnosed head and neck cancer patients.

Malnutrition, which can be determined by subjective and objective methods, has a high prevalence in head and neck cancer patients. Subjective Global Assessment is a subjective method of nutritional status evaluation. Phase angle, determined by bioelectrical impedance analysis, is proposed as an objective nutritional marker in various disease conditions. The study was conducted to investigate the association between phase angle and Subjective Global Assessment to validate the determination of the nutrition status in adult patients with head and neck cancer. In a prospective cohort study, patients were classified as either well-nourished or malnourished using the Subjective Global Assessment. Phase angle measured by bioelectrical impedance analysis was planned in 75 naive patients with histologically confirmed head and neck cancer. Receiver operating characteristic curves were estimated using the non-parametric method to determine the optimal cut-off level of phase angle. The study was conducted on a cohort population of 75 patients. Well-nourished patients (n = 45) had a statistically significantly higher (p = 0.005) median phase angle score (5.25º) as compared to those who were malnourished (4.73º) (n = 30). A phase angle cut-off of 4.73 was 80 % sensitive and 56.7 % specific in detecting malnutrition diagnosed by SGA in these populations. Phase angle is considered to be a nutritional indicator in patients with head and neck cancer in detecting malnutrition. Further observations are needed to calculate survival, and validate the prognostic significance of phase angle. For future studies, it is important to indicate the specificity of the PA in comparison to SGA measurement.

Preoperative neutrophil-lymphocyte count ratio helps predict the grade of glial tumor - a pilot study.

UNLABELLED: Neutrophil-lymphocyte count ratio (NLCR) is a recognized prognostic marker for renal, lung or colorectal carcinomas. The aim of the present study was to determine whether the preoperative value of NLCR might serve as a predictive marker for glial tumors' grading. METHODS: The retrospective analysis of NLCR was performed in neurosurgical patients treated for glial brain tumors. The preoperative NLCR was analyzed in accordance with WHO glial tumors' classification, which distinguishes G1, G2, G3 and G4 (glioblastoma) tumors. RESULTS: The analysis of NLCR was performed in 424 patients (258 males and 166 females) aged 53 ± 16 years who underwent either an open surgery or stereotactic biopsy for a glial brain tumor. G1 was diagnosed in 22 patients, G2 - in 71 patients, G3 - in 63 patients and G4 - in 268 patients. The highest value of NLCR was noted in G4 patients (5.08 [3.1; 8.7] - median [quartiles 1 and 3, respectively]) and was significantly higher compared to G3 (p<0.01), G2 (p<0.001) and G1 (p<0.01) groups. Moreover, NLCR was significantly higher in group G3 than G2 (p<0.05). ROC curve analysis showed 2.579 as a cut-off point for prediction of glioblastoma. CONCLUSION: Preoperative NLCR measurement corresponds with a glial brain tumor grading.

Epidemiology of intestinal parasitic infections in school children in Ghazni Province, eastern Afghanistan.

OBJECTIVE: To estimate the prevalence of intestinal parasites and their species in Afghan school children and to establish appropriate treatment methods for detected pathogens. METHODS: Parasitological examination of stool samples collected from 1369 children aged 8-18, students of the Jahan Malika High School in Ghazni Province in eastern Afghanistan, was conducted in the period November 2013-April 2014. Three stool samples were collected from each patient every second day; the samples were fixed in 10% formalin and tested by light microscopy using the methods of direct smear in Lugol's solution, decantation in distilled water, and Fülleborn's flotation. RESULTS: Of 535 examined children (39.1% of the study group) were infected with nematodes (n=324), cestodes (n=118), trematodes (n=12), and protozoa (n=228), 132 were diagnosed with co-infections (mainly ascariasis+giardiasis, ascariasis+hymenolepiasis) and received single or combined therapy. CONCLUSIONS: The Afghan community is an example of population characterized by a high rate of parasitic infections. Owing to high prevalence of multiple infections among inhabitants of Afghanistan, it seems that a mass deworming campaign with a single-dose chemotherapy may prove ineffective in eradicating intestinal parasites in the local population.

Body composition analysis in head and neck squamous cell carcinoma.

Direct bioimpedance measures [resistance, reactance, phase angle] determined by bioelectrical impedance analysis (BIA) detect changes in tissue electrical properties. Bioelectrical impedance analysis vector (BIVA) technique is a promising tool, using the pure data obtained by BIA evaluation for the screening and monitoring of nutrition and hydration status. BIVA has the potential to be used as a routine method in the clinical setting for the assessment and management of body fluids. The study was conducted to evaluate soft tissue hydration and mass through pattern analysis of vector plots as height, normalized resistance, and reactance measurements by bioelectric impedance vector analysis in patients with head and neck cancer. Whole body measurements were made with ImpediMed bioimpedance analysis in 134 adult, white, male subjects 22-87 years old: 67 patients with head and neck cancer (H&NC) and 67 healthy volunteers matched by sex, age and BMI as a control group. All patients were previously untreated and without active nutritional interventions. Mean vectors of H&NC group versus the control group were characterized by an increased normalized resistance component with a reduced reactance component (separate 95% confidence limits, P < 0.05). BIVA may offer objective measures to improve clinical decision-making and predict outcomes. In patients with H&NC to reduce post-operational complications monitoring bioimpedance vector trajectory may support therapy planning of individual patients before surgery.

[Assessment of the angle between puborectal muscles in women with and without stress urinary incontinence in three-dimensional sonograph]. / Ocena kata miedzy miesniami lonowo-odbytniczymi u kobiet z nietrzymaniem moczu i bez niego z zastosowaniem trójwymiarowej ultrasonografii.

UNLABELLED: Contemporary care of the woman, especially in the postmenopausal period is based not only on gynaecological periodic inspections, but also on the routine evaluation of the pelvis minorwith the ultrasound examination. Based on this examination we can manytimes initially diversify causes of wrong manifestations, so like, e.g., urinary incontinence, of social pathologies coming into existence in the result rolling within the pelvis minor. Urinary incontinence is a complaint which is changing the quality of life. Three-dimensional sonography (3D USG) supplies us more information than traditional two-dimensional sonography. It let us to make dynamic representation of examining structures and let us to observe them in any angle we need. The best way for sonographic examination of lower pelvis minor is translabial sonography, because it doesn't change mutual relationship of any parts in lower pelvic area, just like transrectal ortransvaginal probes can make. For good treatment of symptoms of urinary incontinence we have to perform not only functional examination of lower urinary tract, but also make very accurate rate of the static of female genital organs and pelvic floor. BACKGROUND: The aim of study was to rate the angle between both puborectal muscles measurements using translabial three-dimensional sonography in women with stress urinary incontinence without descension of the female genital tract. MATERIAL AND METHODS: Studied group included 100 patients who were examined with GE Kretz Voluson 730 (GE, Austria) scaner equipped 6-9 MHztranslabial probe. First group with stress urinary incontinence comprised 50 women in the mean age 56.22 (+/- 10.43) years old and the second without symptoms--50 women in the mean age 49.0 (+/- 13.22) years old. All cases of urinary stress incontinence in first group was confirm with urodynamic examination. Women in both groups were in similar body mass index, means (+/-SD): 26.88 (+/- 2.02) and 26.20 (+/- 4.14), respectively. Menopausal status in both groups was not statistically significant and aggregate 7.21 (+/- 8.71) in group of women with stress urinary incontinence and 4.70 (+/- 6.32) in group of women without symptoms. Means (+/- SD) quantity of deliveries was significantly higher in group of women with stress urinary incontinence than in control group and amount to 2.40 (+/- 1.03) and 1.56 (+/- 1.34), respectively. In all cases 3D USG coronal view of pelvic diaphragm was obtained and the angle between both puborectal muscles were measured. All women had about 200 ml urine in the bladder. RESULTS: Means (+/-SD) of this angle in these groups were 65.48 +/- 9.22 and 58.64 +/- 9.17 degrees, respectively. The differences between both groups in all measurements were statistically significant (p<0.0015). CONCLUSION: Stated during translabial three-dimensional ultrasound examination considerably different values of the angle between puborectal muscles at women with and without the urinary incontinence can be more helpful in a accurate diagnosing of the type of the urinary incontinence.

Association of serum adiponectin, leptin, and resistin concentrations with the severity of liver dysfunction and the disease complications in alcoholic liver disease.

BACKGROUND AND AIMS: There is growing evidence that white adipose tissue is an important contributor in the pathogenesis of alcoholic liver disease (ALD). We investigated serum concentrations of total adiponectin (Acrp30), leptin, and resistin in patients with chronic alcohol abuse and different grades of liver dysfunction, as well as ALD complications. MATERIALS AND METHODS: One hundred forty-seven consecutive inpatients with ALD were prospectively recruited. The evaluation of plasma adipokine levels was performed using immunoenzymatic ELISA tests. Multivariable logistic regression was applied in order to select independent predictors of advanced liver dysfunction and the disease complications. RESULTS: Acrp30 and resistin levels were significantly higher in patients with ALD than in controls. Lower leptin levels in females with ALD compared to controls, but no significant differences in leptin concentrations in males, were found. High serum Acrp30 level revealed an independent association with advanced liver dysfunction, as well as the development of ALD complications, that is, ascites and hepatic encephalopathy. CONCLUSION: Gender-related differences in serum leptin concentrations may influence the ALD course, different in females compared with males. Serum Acrp30 level may serve as a potential prognostic indicator for patients with ALD.

Performance of IOTA Simple Rules Risks, ADNEX Model, Subjective Assessment Compared to CA125 and HE4 with ROMA Algorithm in Discriminating between Benign, Borderline and Stage I Malignant Adnexal Lesions.

BACKGROUND: Borderline ovarian tumors (BOTs) and early clinical stage malignant adnexal masses can make sonographic diagnosis challenging, while the clinical utility of tumor markers, e.g., CA125 and HE4, or the ROMA algorithm, remains controversial in such cases. OBJECTIVE: To compare the IOTA group Simple Rules Risk (SRR), the ADNEX model and the subjective assessment (SA) with serum CA125, HE4 and the ROMA algorithm in the preoperative discrimination between benign tumors, BOTs and stage I malignant ovarian lesions (MOLs). METHODS: A multicenter retrospective study was conducted with lesions classified prospectively using subjective assessment and tumor markers with the ROMA. The SRR assessment and ADNEX risk estimation were applied retrospectively. The sensitivity, specificity, positive and negative likelihood ratios (LR+ and LR-) were calculated for all tests. RESULTS: In total, 108 patients (the median age: 48 yrs, 44 postmenopausal) with 62 (79.6%) benign masses, 26 (24.1%) BOTs and 20 (18.5%) stage I MOLs were included. When comparing benign masses with combined BOTs and stage I MOLs, SA correctly identified 76% of benign masses, 69% of BOTs and 80% of stage I MOLs. Significant differences were found for the presence and size of the largest solid component (p = 0.0006), the number of papillary projections (p = 0.01), papillation contour (p = 0.008) and IOTA color score (p = 0.0009). The SRR and ADNEX models were characterized by the highest sensitivity (80% and 70%, respectively), whereas the highest specificity was found for SA (94%). The corresponding likelihood ratios were as follows: LR+ = 3.59 and LR- = 0.43 for the ADNEX; LR+ = 6.40 and LR- = 0.63 for SA and LR+ = 1.85 with LR- = 0.35 for the SRR. The sensitivity and specificity of the ROMA test were 50% and 85%, respectively, with LR+ = 3.44 and LR- = 0.58. Of all the tests, the ADNEX model had the highest diagnostic accuracy of 76%. CONCLUSIONS: This study demonstrates the limited value of diagnostics based on CA125 and HE4 serum tumor markers and the ROMA algorithm as independent modalities for the detection of BOTs and early stage adnexal malignant tumors in women. SA and IOTA methods based on ultrasound examination may present superior value over tumor marker assessment.

The Impact of the War in Ukraine on the Epidemiological Situation of Tuberculosis in Europe.

Ukraine is at the forefront of one of the largest outbreaks of tuberculosis (TB) in Europe, including multidrug-resistant tuberculosis. Due to the ongoing armed conflict in this area, there is a significant number of refugees from Ukraine to other European countries. The aim of the study is to emphasize the essence of the problem of the increased incidence of tuberculosis, taking into account the impact of the armed conflict in Ukraine, resulting in the intensification of migration movements. A descriptive epidemiological method was used as the research method. The material was collected by analyzing source statistical data from WHO and statistical yearbooks of selected European countries. Particularly, Ukrainian refugees in Poland, Germany, the Czech Republic, and Slovakia are at higher risk of contracting tuberculosis due to factors like migration stress, poor nutrition, and comorbidities. Epidemiological data from these countries show a rise in tuberculosis cases among foreigners, emphasizing the need for European specialists to be more vigilant in this unique situation, focusing on refugees and other vulnerable populations. More research and collaborative efforts are essential to closely monitor and prevent the severe outcomes of tuberculosis transmission.

Extracorporeal Rewarming Is Associated With Increased Survival Rate in Severely Hypothermic Patients With Preserved Spontaneous Circulation.

Treatment recommendations for rewarming patients in severe accidental hypothermia with preserved spontaneous circulation have a weak evidence due to the absence of randomized clinical trials. We aimed to compare the outcomes of extracorporeal versus less-invasive rewarming of severely hypothermic patients with preserved spontaneous circulation. We conducted a multicenter retrospective study. The patient population was compiled based on data from the HELP Registry, the International Hypothermia Registry, and a literature review. Adult patients with a core temperature <28°C and preserved spontaneous circulation were included. Patients who underwent extracorporeal rewarming were compared with patients rewarmed with less-invasive methods, using a matched-pair analysis. The study population consisted of 50 patients rewarmed extracorporeally and 85 patients rewarmed with other, less-invasive methods. Variables significantly associated with survival included: lower age; outdoor cooling circumstances; higher blood pressure; higher PaCO 2 ; higher BE; higher HCO 3 ; and the absence of comorbidities. The survival rate was higher in patients rewarmed extracorporeally ( p = 0.049). The relative risk of death was twice as high in patients rewarmed less invasively. Based on our data, we conclude that patients in severe accidental hypothermia with circulatory instability can benefit from extracorporeal rewarming without an increased risk of complications.

Bioimpedance vector pattern in Taiwanese and Polish college students detected by bioelectric impedance vector analysis: preliminary observations.

BACKGROUND AND OBJECTIVES: The study was conducted to evaluate soft tissue hydration and mass through pattern analysis of vector plots as height, normalized resistance, and reactance measurements by bioelectric impedance vector analysis in Taiwanese and Polish college students. METHODS: Whole-body measurements were made with ImpediMed bioimpedance analysis SFB7 BioImp v1.55 (Pinkenba Qld 4008, Australia) in 16 Taiwanese and Polish men and 16 Taiwanese and Polish women. RESULTS: Mean vectors of Taiwanese men and women groups versus the Polish men and women groups were characterized by almost the same normalized resistance component with reactance component (separate 95% confidence limits, P < 0.05) indicating that there were no differences of soft tissue hydration and mass. INTERPRETATION AND CONCLUSION: The evaluation of soft tissue hydration and mass through pattern analysis of vector plots as height, normalized resistance, and reactance measurements by bioelectric impedance vector analysis in Taiwanese and Polish college students did not differ between these two diverse ethnic groups. Further observational research investigating these properties in larger groups would be welcomed to elucidate and/or confirm these findings.

[Sonographic evaluation of the levator ani muscle in women with stress urinary incontinence]. / Ultrasonograficzna ocena miesnia dzwigacza odbytu u kobiet z wysilkowym nietrzymaniem moczu.

UNLABELLED: Three-dimensional sonography has been used for about 15 years, not only to examine the female genital organs, but also the lower urinary tract and pelvic floor. Three-dimensional sonography offers more information than traditional two-dimensional sonography allowing for a dynamic representation of the examined structures and observation at any angle necessary. Translabial sonography is the best way of a sonographic examination of the lower urinary tract, because it does not affect the mutual relationship of any parts in the lower pelvic area, contrary to the transrectal or transvaginal probes. In order to establish proper treatment of the urinary incontinence symptoms, not only a functional examination of the lower urinary tract, but also a very accurate assessment of the statics of the female genital organs and pelvic floor need to be performed. BACKGROUND: The aim of the study was to rate the area and diameters of the limbs of the levator ani muscle using a three-dimensional (3D) translabial sonography in women with stress urinary incontinence without the female genital tract prolapse. MATERIAL AND METHODS: The study group included 100 patients who were examined with the GE Kretz Voluson 730 (GE, Austria), equipped with 6-9 MHz translabial probe. The first group with stress urinary incontinence consisted of 50 women (mean age 56.22 (+/- 10.43) years) and the second group included 50 women without symptoms (mean age 49.40 (+/- 13.22) years). All cases of urinary stress incontinence in the first group were confirm by means of a urodynamic examination. Women in both groups had similar body weight (kilograms), mean (+/- SD): 26.88 (+/- 2.02) and 26.20 (+/- 4,14), respectively. Menopausal status in both groups was not statistically significant and amounted to 7.21 (+/- 8.71) in the group of women with stress urinary incontinence and 4.70 (+/- 6.32) in the group without symptoms. Mean (+/- SD) number of deliveries was significantly higher in the group of women with stress urinary incontinence than in the control group (2.40 (+/- 1.03) and 1.56 (+/- 1.34), respectively). In all cases 3D coronal view of the pelvic diaphragm was obtained and the area and thickness of limbs of the levator ani muscle were measured. All women had about 200 ml urine in the bladder. RESULTS: The results are presented as means +/- SD. Mean measurements of this area in both groups were 8.54 +/- 1.62 cm2 and 10.57 +/- 1.29 cm2, respectively. Mean thickness of the limbs in the groups were: 8.72 +/- 0.64mm and 10.85 +/- 0.89mm on the left side and 8.85 +/- 0.67mm and 10.89 +/- 0.87mm on right side, respectively. The differences between both groups in all measurements were statistically significant (p < 0.001). CONCLUSIONS: There are some differences involving measurements of the thickness and the area of the limbs of the levator ani muscle in women with and without stress urinary incontinence and without the genital tract prolapse in both groups. The observed differences could have implications in physiotherapy of the pelvic floor muscles in women without statics abnormalities.

Application of bioelectrical impedance analysis in monitoring patients with head and neck cancer after surgical intervention.

INTRODUCTION: It is estimated that about 60% of patients with head and neck cancer (HNC) show poor nutritional status, and approximately 80% lose weight during treatment. The impact of surgical procedures on the risk of further weight loss, severe malnutrition and cachexia is a significant clinical problem that determines the higher incidence of postoperative complications, reduced effectiveness of the treatment used, longer hospitalization time, poor quality of life and higher mortality among patients. Bioelectrical impedance analysis (BIA) is currently recognized as a useful method of assessing the body composition and therefore the nutritional status of cancer patients. The aim of this study is to investigate whether measured and calculated parameters of BIA change shortly after surgery and could reflect the health of cells and body composition changes. MATERIALS AND METHODS: We enrolled 54 patients (males) with advanced HNC in this observational study. We collected detailed anthropometric and BIA derived data. The Subjective Global Assessment (SGA) was used to assess the nutrition. RESULTS: In the assessment performed one week after the surgery, compared to the condition on the day of surgery, the patients had significantly lower values of nutritional status (weight; body mass index - BMI; SGA), body composition (free fat mass - FFM; intracellular fluid - ICF; total body water - TBW). Other changes include a significant increase in fat mass (FM) or extracellular fluid (ECF). Moreover, a significant reduction of phase angle (PA, one of the most important BIA derived prognostic factors) was also noted. CONCLUSIONS: Apart from the baseline assessment of the body composition and diagnosing nutritional disorders, it seems, that BIA should be considered also in the monitoring of HNC patients undergoing surgery.

Evaluation of tracheal stenosis: comparison between computed tomography virtual tracheobronchoscopy with multiplanar reformatting, flexible tracheofiberoscopy and intra-operative findings.

The aim of the study was to evaluate and compare various helical CT display modes [virtual endoscopy (VE)] and multiplanar reformations (MPR), conventional flexible tracheobronchoscopy (FT) and intra-operative (IO) findings in patients with tracheal stenosis and to analyze the advantage of MPR and VE in diagnosis and treatment planning and in postoperative follow-up. Thirty-seven patients with tracheal stenosis underwent standard neck and chest CT followed by MPR and VE. Results were correlated with the results of FT and IO findings. Thirty-three of the 37 stenoses were correctly graded and measured adequately using VE. Complete correlation among CT, fiberoptic tracheoscopy, and surgery of stenosis grading, stenosis length and length of planned resection segment of the trachea was noted between 33 of 37 patients with tracheal stenosis. Correlation between VE and IO was noted in 35 of 37 patients and between FT and VE was noted in 33 of 37 patients with tracheal stenosis. The sensitivity of VE was 94-97%, specificity was 100% with comparison to IO findings. The sensitivity and accuracy of MPR was 86-89% and specificity was 100% with comparison to FT findings. The results of the study indicate that VE is an excellent, consistent, and objective technique. VE with MPR is very useful in diagnostic evaluation and treatment planning in patients with tracheal stenosis.

Effect of Spirulina Supplementation on Systolic and Diastolic Blood Pressure: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Spirulina is a microalga that presents various important pro-health properties, for instance lowering blood pressure in the research. The study aims to appraise the efficacy of Spirulina administration on systolic (SBP) and diastolic blood pressure (DBP). Randomized controlled trials (RCTs) were retrieved by a systematic search of PubMed, Web of Science, and the Cochrane Library databases from inception to June 2021 according to a standardized protocol. The effect size of each study was counted from mean and standard deviation before and after the intervention and shown as Un-standardized mean difference and 95% confidence interval. Sensitivity analyses were performed. Meta-analysis on 5 RCTs with 230 subjects was eligible. The amount of Spirulina ranged from 1 to 8 g per day, and intervention durations ranged from 2 to 12 weeks. Data analysis indicated that Spirulina supplementation led to a significant lowering of SBP (Mean Difference (MD): -4.59 mmHg, 95% Confidence Interval (CI): -8.20 to -0.99, I square statistic (I2) = 65%) and significant lowering of DBP (MD: -7.02 mmHg, CI: -8.86 to -5.18, I2 = 11%), particularly in a subgroup of hypertensive patients. Spirulina administration might have a supportive effect on the prevention and treatment of hypertension. More exact randomized controlled trials are needed to clarify the effect of Spirulina supplementation on blood pressure.
