Influence of Androgen Deprivation Therapy on the Development of Sarcopenia in Patients with Prostate Cancer: A Systematic Review.

The changes in body composition during androgen deprivation therapy (ADT) in patients suffering from prostate cancer (PCa) are recognized by professionals more often as biomarker for effective treatment. The aim of this study was to investigate the impact of ADT on the sarcopenia development in PCa. The following databases were used: PubMed, Embase, Web of Science and Scopus databases. Out of 2183 studies, 7 were included in this review. The fixed-effect model was used in the meta-analysis. A significant increase in SATI (Subcutaneous Adipose Tissue Index) of 0.32 (95% CI: 0.13-0.51) p = 0.001, decrease in SMI (Skeletal Muscle Index) of -0.38 (95% CI: -0.57 to -0.19) p < 0.0001, and SMD (Skeletal Muscle Density) of -0.46 (95% CI: -0.69 to -0.24) p < 0.0001 were observed. No statistical association was visible between ADT and changes in BMI (Body Mass Index), 0.05 (95% CI: -0.18-0.28), p = 0.686, and VATI (Visceral Adipose Tissue Index): 0.17 (95% CI: -0.02 to 0.37), p = 0.074. In conclusion, the ADT significantly contributes to the body composition changes and sarcopenia development.

Prognostic factors in patients with uterine sarcoma: the SARCUT study.

OBJECTIVE: Uterine sarcomas are a rare and heterogeneous group of malignancies that include different histological sub-types. The aim of this study was to identify and evaluate the impact of the different prognostic factors on overall survival and disease-free survival of patients with uterine sarcoma. METHODS: This international multicenter retrospective study included 683 patients diagnosed with uterine sarcoma at 46 different institutions between January 2001 and December 2007. RESULTS: The 5-year overall survival for leiomyosarcoma, endometrial stromal sarcoma, undifferentiated sarcoma, and adenosarcoma was 65.3%, 78.3%, 52.4%, and 89.5%, respectively, and the 5-year disease-free survival was 54.3%, 68.1%, 40.3%, and 85.3%, respectively. The 10-year overall survival for leiomyosarcoma, endometrial stromal sarcoma, undifferentiated sarcoma and adenosarcoma was 52.6%, 64.8%, 52.4%, and 79.5%, respectively, and the 10-year disease-free survival was 44.7%, 53.3%, 40.3%, and 77.5%, respectively. The most significant factor associated with overall survival in all types of sarcoma except for adenosarcoma was the presence of residual disease after primary treatment. In adenosarcoma, disease stage at diagnosis was the most important factor (hazard ratio 17.7; 95% CI 2.86 to 109.93). CONCLUSION: Incomplete cytoreduction, tumor persistence, advanced stage, extra-uterine and tumor margin involvement, and the presence of necrosis were relevant prognostic factors significantly affecting overall survival in uterine sarcoma. The presence of lymph vascular space involvement and administration of adjuvant chemotherapy were significantly associated with a higher risk of relapse.

Androgen Deprivation Therapy for Prostate Cancer Influences Body Composition Increasing Risk of Sarcopenia.

Computed tomography (CT) scans used in treatment response assessment in prostate cancer (PCa) patients are a useful tool for nutritional status evaluation. The aim of this study was to assess the nutritional status, including sarcopenia development based on CT scans, in PCa patients and its association with progression-free survival (PFS). Sixty-four PCa patients were included (group 1: 34 patients undergoing androgen deprivation therapy (ADT) with docetaxel due to newly diagnosed, hormone-sensitive, metastatic PCa and group 2: 30 patients with castration-resistant metastatic PCa continuing ADT therapy with enzalutamide or abiraterone acetate). Nutritional status was evaluated with anthropometrical parameters, Nutritional Risk Score (NRS), and CT scans at the L3 vertebrae. Survival analyses were performed. According to NRS, nutritional status was significantly related to PFS. In both groups, there was a significant reduction in muscle tissue (total muscle tissue and skeletal muscle index). A significant increase in the distribution of adipose tissue (subcutaneous fat, visceral fat, subcutaneous adipose tissue index, and visceral adipose tissue index) in group one was observed. Sarcopenia was diagnosed in patients but with no influence on PFS. Significant reduction in muscle mass and increase in fat mass was observed in patients treated for PCa with no impact on PFS. The NRS was related to PFS in PCa patients and associated with body composition, assessed by CT after the castration therapy. Long-term castration combined with abiraterone therapy with prednisone or enzalutamide significantly influenced muscle tissue and may lead to sarcopenia development.

Microbiome Composition in Microscopic Colitis: A Systematic Review.

Believed to be a rare cause of chronic diarrhoea, microscopic colitis (MC) is a condition with rising incidence. Many prevalent risk factors and the unknown pathogenesis of MC rationalise the need for studies on microbiota composition. PubMed, Scopus, Web of Science and Embase were searched. Eight case-control studies were included. The risk of bias was assessed with the Newcastle-Ottawa Scale. Clinical details on the study population and MC were poor. The most consistent result among the studies was a decreased Akkermansia genus in faecal samples. Other results were inconsistent due to the different taxonomic levels of the outcomes. Possible changes in different taxa were observed in patients who suffered from MC compared to healthy controls. The alpha diversity compared between MC and the diarrhoea control may suggest potential similarities. The beta diversity in MC compared to healthy and diarrhoeal populations showed no significant outcomes. The microbiome composition in MC possibly differed from the healthy control, but no agreement regarding taxa was made. It might be relevant to focus on possible factors influencing the microbiome composition and its relationship with other diarrhoeal diseases.

The Automatic Algorithm of the Auto-CPAP Device as a Tool for the Assessment of the Treatment Efficacy of CPAP in Patients with Moderate and Severe Obstructive Sleep Apnea Syndrome.

Obstructive sleep apnea syndrome (OSAS) is a common sleep-related breathing disorder where precise treatment assessment is of high importance. We aimed to validate an automatic algorithm of the auto-CPAP device and reveal polygraph usefulness in the OSAS diagnosis and treatment of outpatients. One hundred patients with moderate OSAS, severe OSAS, and excessive daytime sleepiness qualified for CPAP treatment were included. The study was conducted in three stages. The first stage included a minimum 6-hour polysomnographic examination to select moderate and severe OSAS. The second stage involved an auto-CPAP treatment lasting at least 4 h with simultaneous polygraph recording. The third stage was a titration of at least 4 h with auto-CPAP. The Apnea-Hypopnea Index (AHI) and oxygen desaturation index (ODI) were calculated under auto-CPAP treatment, simultaneously using polygraph (stage two), and as a result of treatment with auto-CPAP (stage three). The mean AHI was 40.0 ± 20.9 for OSAS. Auto-CPAP treatment was effective in 97.5%. The mean residual AHI was 8.6 ± 4.8; there was no significant difference between the AHI CPAP, and the AHI polygraph values were assessed with an accuracy of 3.94/h. The sensitivity and specificity of calculated cut point 8.2 event/hour were: 55% and 82%, respectively. The calculated AUC for the AHI CPAP parameter was 0.633. Presented data confirmed that the automatic algorithm of auto-CPAP is a good tool for the assessment of the treatment efficacy of CPAP in patients, i.e., home setting, with a moderate or severe stage OSAS-presented high sleepiness.

Immunohistochemical Expression of Vitamin D Receptor in Uterine Fibroids.

One of the many factors involved in the development of uterine fibroids is vitamin D deficiency. One aspect of this deficiency is decreased serum concentration of calcidiol-25(OH)D, a metabolite of D3 vitamin. The active form of vitamin D3, which arises after numerous enzymatic reactions, is calcitriol-1,25(OH)2D3; this compound is transported to various body tissues. Vitamin D possesses extra-genomic effects due to its influence on various signaling pathways, i.e., through activating tyrosine kinases and by genomic effects via binding to a specific nuclear receptor, vitamin D receptor (VDR). The vitamin D/VDR complex regulates the expression of genes and is involved in the pathogenesis of fibroids. Numerous studies have shown that vitamin D supplementation reduces fibroid size. It has also been shown that the expression of VDR in myoma tissue is significantly lower than in the uterine muscle tissue at the tumor periphery. However, the expression of VDR in non-myoma uterine muscle has not previously been investigated. Our VDR expression studies were performed immunohistochemically with tissue microarrays (TMA) in three tissue groups: 98 uterine myoma tissues, 98 uterine tissues (tumor margin), and 12 tissues of normal uterine muscle (i.e., without fibroids). A statistical analysis showed significantly lower VDR expression in uterine muscle at the periphery of the fibroid than in healthy uterine muscle. Lower expression of VDR at the periphery of the myoma compared to that in normal uterine muscle may indicate potential for new myomas. This observation and the described reduction in the size of fibroids after vitamin D supplementation supports the hypothesis of causal development of uterine fibroids and may be useful for the prevention of re-development in the event of their excision from the uterus.

Influence of Probiotics in Prevention and Treatment of Patients Who Undergo Chemotherapy or/and Radiotherapy and Suffer from Mucositis, Diarrhoea, Constipation, Nausea and Vomiting.

The administration of probiotics to patients treated with chemo- and/or radiotherapy is assumed to be beneficial. The aim of this study was to evaluate the effects of probiotic intake on the severity of selected gastrointestinal side effects of chemotherapy and radiotherapy. The searched databases included PubMed, Web of Science, and Scopus from which twenty-one studies were included. Most of them concerned diarrhoea, however, two of the studies examined constipation, another two nausea and vomiting, and eight of the included studies regarded mucositis. The total number of patients equalled 2621. The time of the conducted therapy, the administered species, neoplasm pathology, and adjuvant therapy varied. The outcome was assessed by gathering information about the statistical significance of the improvements. An enhancement was observed in thirteen studies, where probiotics had a significant impact on each of the included chemo- and/or radiotherapy side effects. However, the heterogeneity of the assessed data makes it impossible to state a firm conclusion.

Influence of Gluten-Free Diet on Gut Microbiota Composition in Patients with Coeliac Disease: A Systematic Review.

The aim of this study was to assess the changes in microbiota composition during a gluten-free diet (GFD) in coeliac disease (CD) patients. The systematic search followed databases such as PUBMED (MEDLINE), SCOPUS, WEB OF SCIENCE and EMBASE. Out of 843 initially screened papers, a total number of 13 research papers were included. A total of 212 patients with CD on GFD, in comparison to 174 healthy individuals and 176 untreated patients with CD, were examined. Analysis of the microbial community based primarily on faecal samples and duodenal biopsies. Bifidobacterium was noticed to be less abundant in the study group than in both control groups, while the abundance of Bacteroides was more numerous in the group of CD patients on GFD. Staphylococcaceae prevailed in untreated CD patients. Despite the fact that the GFD was not able to fully restore commensal microorganism abundance, the treatment was associated with the greater abundance of selected beneficial bacteria and lower presence of pathogenic bacteria associated with worsening of CD symptoms.

Association between Anxiety, Depressive Symptoms, and Quality of Life in Patients Undergoing Diagnostic Flexible Video Bronchoscopy.

Bronchoscopy is one of the basic invasive procedures in pulmonology accompanied by patients' anxiety. This study aimed to find an association between predictors of state anxiety/depression and patient's quality of life (QOL) with pulmonary symptoms undergoing diagnostic flexible video bronchoscopy (FVB). A total of 125 adult patients before FVB were included in a prospective observational study. The quality of life (QOL) was assessed by WHOQOL-BREF questionnaire, the depression possibility by the Beck's Depression Inventory-II (BDI-II), and the anxiety level by Spielberger's State-Trait Anxiety Inventory (STAI-S; STAI-T). Results show that the older patients and patients with more comorbidities showed a significantly higher anxiety level. The previous FVB under deep sedation significantly reduced state anxiety. A significantly positive association was found between the STAI score and total BDI-II score. More severe symptoms of anxiety were especially related to lower QOL (physical health, psychological and environmental domains) in patients. Statistically higher trait anxiety in lower social QOL domain scores was observed. Our findings show that high state and trait anxiety were associated with higher depression scores and lower quality of life in the elderly. It seems that the elderly and patients at risk of depression development require more attention in the clinical setting to minimize the anxiety accompanying the bronchoscopy.

Role of Probiotics in Modulating Human Gut Microbiota Populations and Activities in Patients with Colorectal Cancer-A Systematic Review of Clinical Trials.

BACKGROUND: Growing attention has been given to the role of nutrition and alterations of microbial diversity of the gut microbiota in colorectal cancer (CRC) pathogenesis. It has been suggested that probiotics and synbiotics modulate enteric microbiota and therefore may be used as an intervention to reduce the risk of CRC. The aim of this study was to evaluate the influence of probiotics/synbiotics administration on gut microbiota in patients with CRC. METHODS: PubMed, Scopus, and Web of Science were searched between December 2020 and January 2021. Randomized controlled trials (RCTs) recruiting adults with CRC, who have taken probiotics/synbiotics for at least 6 days were included. Changes in gut microbiota and selected biochemical and inflammatory parameters (i.e., hsCRP, IL-2, hemoglobin) were retrieved. RESULTS: The search resulted in 198 original research articles and a final 6 were selected as being eligible, including 457 subjects. The median age of patients was 65.4 years old and they were characterized by the median BMI value: 23.8 kg/m2. The literature search revealed that probiotic/synbiotic administration improved enteric microbiota by increasing the abundance of beneficial bacteria such as Lactobacillus, Eubacterium, Peptostreptococcus, Bacillus and Bifidobacterium, and decreased the abundance of potentially harmful bacteria such as Fusobacterium, Porhyromonas, Pseudomonas and Enterococcus. Additionally, probiotic/synbiotic intervention improved release of antimicrobials, intestinal permeability, tight junction function in CRC patients. CONCLUSIONS: The use of probiotics/synbiotics positively modulates enteric microbiota, improves postoperative outcomes, gut barrier function and reduces inflammatory parameters in patients suffering from CRC.

Interventions Preventing Vaginitis, Vaginal Atrophy after Brachytherapy or Radiotherapy Due to Malignant Tumors of the Female Reproductive Organs-A Systematic Review.

BACKGROUND: Radiotherapy, as a method of treatment of cervical and uterine cancers, may induce severe late-onset vaginal side effects. Unfortunately, little evidence on the management of adverse effects has been presented. This study aimed to evaluate the available interventions which reduce symptoms of vaginitis and vaginal atrophy by improving dyspareunia, mucosal inflammation, vaginal pH and vaginal dryness in women who have undergone brachytherapy or radiotherapy due to uterine or cervical malignancies. MATERIALS AND METHODS: A comprehensive literature search was performed following PRISMA guidelines. The systematic search was conducted using electronic databases, namely Scopus, Web of Science and PubMed, between October and November 2020 to identify randomized controlled trials (RCT) and, prospective randomized studies (PRS). RESULTS: The analyzed population consists of 376 patients with uterine or cervical cancer, treated with hyaluronic acid, vitamin A, vitamin E, alpha-tocopherol acetate and dienestrol. Intervention with HA along with vitamin A and vitamin E revealed advantage in endpoints such as reduced dyspareunia, vaginal mucosal inflammation, vaginal dryness, bleeding, fibrosis and cellular atypia. Administration of alpha-tocopherol acetate reduced vaginal mucosal inflammation and improved vaginal acanthosis, whereas dienestrol resulted in reduced dyspareunia, vaginal caliber and bleeding. CONCLUSIONS: Vaginal suppositories were found to be clinically effective at the management of late-onset vulvovaginal side effects after radiotherapy.

Body Mass Index Reduction and Selected Cardiometabolic Risk Factors in Obstructive Sleep Apnea: Meta-Analysis.

Although clinical studies have been carried out on the effects of weight reduction in sleep apnea patients, no direct link has been shown between weight reduction and changes in cardio-metabolic risk factors. We aimed to analyze changes in the apnea-hypopnea index and selected cardio-metabolic parameters (total cholesterol, triglycerides, glucose, insulin, blood pressure) in relation to the reduction in body mass index in obstructive sleep apnea patients. Medline, Web of Science and Cochrane databases were searched to combine results from individual studies in a single meta-analysis. We identified 333 relevant articles, from which 30 papers were assigned for full-text review, and finally 10 (seven randomized controlled trials and three nonrandomized studies) were included for data analysis. One unit of body mass index reduction was found to significantly influence changes in the apnea-hypopnea index (-2.83/h; 95% CI: -4.24, -1.41), total cholesterol (-0.12 mmol/L; 95% CI: -0.22, -0.01), triglycerides (-0.24 mmol/L; 95% CI: -0.46, -0.02), fasting insulin (-7.3 pmol/L; 95% CI: -11.5, -3.1), systolic (-1.86 mmHg; 95% CI: -3.57, -0.15) and diastolic blood pressure (-2.07 mmHg; 95% CI: -3.79, -0.35). Practical application of lifestyle modification resulting in the reduction of one unit of body mass index gives meaningful changes in selected cardio-metabolic risk factors in obstructive sleep apnea patients.

Influence of Enteral Nutrition on Gut Microbiota Composition in Patients with Crohn's Disease: A Systematic Review.

The aim of the study was to systematically and comprehensively evaluate whether exclusive enteral nutrition (EEN) has impact on gut microbiota in patients with Crohn's disease (CD). The databases PUBMED (MEDLINE), SCOPUS and WEB OF SCIENCE were searched. Out of 232 studies, 9 met inclusion criteria. The combined analyzed population consists of 118 patients with CD and treated with EEN with a time of intervention of 2-12 weeks. Studies were conducted in children, with the exception of one study. All applied feeding formulas had similar energy value and composition. The microbiome analysis was based on 16S rRNA gene sequencing of faecal samples. In all studies, EEN treatment decreases inflammatory markers (i.e., hs-CRP and FCP). A change in abundance of numerous bacterial families (Clostridiaceae, Eubacteriaceae, Bacteroidaceae) was noticed, especially in Bacteroidaceae. An increase in families connected to the more severe clinical course (Fusobacteria, Prevotella, Lachnospiraceae) was observed in only 2.5% of CD patients. Our analyses suggest EEN has a beneficial influence on gut microbiome in patients with CD, which is interrelated with clinical patient's improvement and time of disease remission.

Link between diet and chemotherapy related gastrointestinal side effects.

AIM OF THE STUDY: To evaluate an association between food products consumption, dietary intake and the incidence of selected gastrointestinal symptoms (nausea, vomiting, diarrhea and constipation) in cancer patients undergoing chemotherapy. MATERIAL AND METHODS: Fifty six women receiving chemotherapy for ovarian cancer were eligible for the study. Anthropometrical measurements were assessed. The dietary intake was evaluated by 24-hours food records. The association between the consumption of selected food products and gastrointestinal symptoms incidences was assessed by modified semi-quantitative food frequency questionnaire including 77-different food items that was developed and applied in cancer patients undergoing chemotherapy. RESULTS: BMI values indicated 9%, 45%, 30% and 16% of patients as underweight, normal weight, overweight and obese respectively. Only 23% and 32% of patients never experienced nausea and constipation when 43% and 45% never experienced vomiting and diarrhea. Nausea was promoted by oils, constipation by chocolate and chocolate products and diarrhea by dairy products, stone fruit and apple. Significant inverse correlations were found between vomiting and the intake of energy, fat, protein, carbohydrates, B groups vitamins, vitamin D, phosphorus and zinc. The difference in energy intake between marginal values of vomiting incidence exceeded 400 kcal. CONCLUSIONS: Dietary intake as well as specific food products influence on gastrointestinal side effect of chemotherapy in cancer patients. The dietary approach based on either exclusion or limited intake of selected food products and improvement of diet could reduce and prevent chemotherapy induced gastrointestinal symptoms therefore should be taken under consideration in clinical practice.

Dietary and cardio-metabolic risk factors in patients with Obstructive Sleep Apnea: cross-sectional study.

BACKGROUND: Little is known about the role of dietary intake in obstructive sleep apnea (OSA), which could prove important in improving clinical outcomes for people with obesity and/or cardiovascular disease within these populations. Reduction in energy intake typically results in weight loss, markedly improving metabolic parameters and ameliorating OSA severity. The aim of this study was to evaluate the association of dietary and cardio-metabolic risk factors with OSA severity. METHODS: This was a cross-sectional study. A total of 75 volunteers at risk of OSA were recruited from 153 patients suffering from sleep disturbance at the Department of Pulmonology, Allergology and Respiratory Oncology at the Poznan University of Medical Sciences. Polysomnography was used for OSA diagnosis. Sleep quality was assessed by the Pittsburgh Sleep Quality Index. Blood pressure, parameters of glucose (fasting glucose, glucose tolerance test) and lipid metabolism (TC, LDL-C, HDL-C, TG) were assessed using routine enzymatic methods. Dietary intake was evaluated by 24-hr dietary recalls and Food Frequency Questionnaire. Ordinal logistic regression models were used for association of background characteristics and dietary intake with OSA severity. All analyses were adjusted for age, sex, BMI, smoking and alcohol intake. RESULTS: A higher percentage of smokers were observed in patients with mild OSA, while alcohol intake was the highest in severe OSA patients. Approximately 60% of the studied patients were self-reported poor sleepers. Results from ordinal logistic regression models showed that higher intakes of alcohol intake were associated with increased odds of severe OSA; whereas higher HDL-C levels were associated with lower odds (OR 0.01; 95% CI [0.0003-0.55]). Significantly higher odds of high OSA severity were observed in patients with disturbed sleep stages and obstructive sleep apnea. Moreover, the investigation of nutrient intake in relation to OSA severity showed that a higher intake of dietary fiber was associated with decreased OSA severity (OR 0.84; 95% CI [0.71-0.98]). CONCLUSIONS: The severity of OSA is related to higher alcohol consumption and disturbed sleep. The significantly lower dietary fiber intake in patients with severe OSA is of particular importance for dietary consulting in clinical practice, which may positively influence cardiometabolic outcomes.

Clinical Utility of Berlin Questionnaire in Comparison to Polysomnography in Patients with Obstructive Sleep Apnea.

The aim of this study was to assess the utility of the Berlin questionnaire (BQ) in adult patients at high risk of obstructive sleep apnea (OSA). The study consisted of 64 patients recruited for the polysomnography diagnostics of sleep respiratory disturbances. The anthropometric assessment included body weight, height, and body mass index (BMI), all related to the risk of OSA. The BQ consisted of the following three categories: 1 - snoring, 2 - daytime somnolence, and 3 - hypertension. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were evaluated. Likelihood ratio was used to assess the diagnostic accuracy. We found that patients were, on average obese; the mean BMI amounted to 31.9 ± 6.0 kg/m2. Polysomnography identified OSA in 73.4% of patients (AHI >5), where the BQ categorized 87.5% of patients at high risk of OSA. Sensitivity of the BQ was 87.2%, specificity 11.8%, PPV 73.2%, and NPV 25.0%. Diagnostic accuracy assessed by the likelihood ratio had a value of 1.00. The BQ had a false discovery rate of 31.2% and misclassification rate of 32.8%. We conclude that the BQ is a sensitive tool that should be used in clinical settings in which the benefit of high sensitivity outweighs the disadvantage of low specificity.

Small Airway Obstruction in Chronic Obstructive Pulmonary Disease: Potential Parameters for Early Detection.

The impulse oscillometry (IOS) is recognized as a complementary method to spirometry in the diagnostics of obstructive pulmonary disorders. The IOS enables to measure total respiratory resistance (R5) and proximal respiratory resistance (R20), with the R5-R20 difference reflecting small airway resistance. This study seeks to evaluate the usefulness of R5-R20, maximal mid-expiratory flow (MMEF), and forced expiratory volume in 3 s/forced vital capacity ratio (FEV3/FVC), in the assessment of small airway obstruction in chronic obstructive pulmonary disease (COPD). One hundred and six COPD patients and 43 control subjects, aged over 55, were investigated. Spirometry and IOS were used to assess pulmonary function. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) were evaluated. The findings demonstrate significant reductions in FEV3/FVC and MMEF, and an increase in R5-R20 difference in COPD patients; the changes that depended on the severity of airway obstruction. The sensitivity of R5-R20 in reflecting the MMEF was 84%, specificity 44.2%, PPV 72.4%, and NPV 61.3%. We conclude that the R5-R20 difference is superior to spirometry in the assessment of small bronchi obstruction. A high sensitivity of R5-R20 in reflecting the MMEF makes the IOS method particularly useful for detection of mild lung injury, while a high specificity of the spirometric FEV3/FVC ratio makes it useful to exclude obstruction of small airways. Both methods are thus complimentary.

Body weight changes in patients undergoing chemotherapy for ovarian cancer influence progression-free and overall survival.

PURPOSE: The aim of this study was to evaluate whether body weight changes in patients undergoing chemotherapy for epithelial ovarian cancer (EOC) influence progression-free survival (PFS) and overall survival (OS). METHODS: An analysis of 190 patients diagnosed with ovarian cancer after first-line chemotherapy was conducted. Changes in body weight were assessed by comparing measurements at baseline to those of the third and sixth cycles of chemotherapy. PFS and OS were calculated with the Kaplan-Meier method and multivariate Cox model. RESULTS: Significant reduction in body weight in advanced EOC was observed with no changes in early EOC. Significant differences in PFS were observed in advanced EOC patients that lost more than 5 % of their body weight (6 months), maintained weight (13 months), or gained more than 5 % of their body weight (15 months). Similarly, significant differences in OS were noted in advanced EOC at the following time points: 24.3, 42.4, and 66.2 months. No effect was reported for early EOC patients. The multivariate Cox analysis showed significant body weight changes from the first to the sixth chemotherapy cycle for PFS (HR = 0.97; 95 % CI 0.95-0.99) and OS (HR = 0.94; 95 % CI 0.91-0.97) as well as from the first to the third chemotherapy cycle for OS (HR = 0.93; 95 % CI 0.88-0.98). CONCLUSIONS: Body weight changes can be recognized as a prognostic factor for PFS and OS in advanced EOC patients undergoing chemotherapy. Weight loss is associated with poorer survival while weight gain improved outcomes.

Quality of life, depression and dietary intake in Obstructive Sleep Apnea patients.

BACKGROUND: The aim of this study was to analyze the association between depression, quality of life and dietary intake in newly diagnosed Obstructive Sleep Apnea (OSA) patients. METHODS: From 153 eligible patients suffering from sleep disturbances, 64 met inclusion and exclusion criteria. The polysomnography was used for OSA diagnosis. The quality of life (QOL) was assessed by WHOQOL-BREF questionnaire, self-reported chronotype by morningness-eveningness questionnaire and level of depression by Beck's Depression Inventory. Blood pressure and parameters of glucose and lipid metabolism were assessed by routine methods. The dietary intake was evaluated by 24-hr dietary recalls. RESULTS: Significantly negative associations were found between depression inventory and QOL. Better QOL for physical health and social relationships was observed in the "definitely morning" chronotype. The "morning type" of patients was positively related to the intake of fat, monounsaturated fatty acids and vitamin B12. Correlations between QOL and diastolic blood pressure, HDL-cholesterol, TG, fasting glucose, as well as protein and vitamin B6 intake were found. CONCLUSIONS: In conclusion, both chornotype and depression influence QOL in OSA patients where morning type is associated with better physical health and social relationships and increase in depression index deteriorate physical health, psychological and social relationship QOL domains. QOL as well as depression and chornotype are also influenced by selected cardio-metabolic factors and dietary intake.
