A Pilot Interaction Analysis of Gut Microbiota and Peripheral Markers of Aging in Severe Psychiatric Disorders: A Role for Lachnoclostridium?

Excessive predominance of pathological species in the gut microbiota could increase the production of inflammatory mediators at the gut level and, via modification of the gut-blood barrier, at the systemic level. This pro-inflammatory state could, in turn, increase biological aging that is generally proxied by telomere shortening. In this study, we present findings from a secondary interaction analysis of gut microbiota, aging, and inflammatory marker data from a cohort of patients with different diagnoses of severe mental disorders. We analyzed 15 controls, 35 patients with schizophrenia (SCZ), and 31 patients with major depressive disorder (MDD) recruited among those attending a community mental health center (50 males and 31 females, mean and median age 46.8 and 46.3 years, respectively). We performed 16S rRNA sequencing as well as measurement of telomere length via quantitative fluorescence in situ hybridization and high-sensitivity C-reactive protein. We applied statistical modeling with logistic regression to test for interaction between gut microbiota and these markers. Our results showed statistically significant interactions between telomere length and gut microbiota pointing to the genus Lachnostridium, which remained significantly associated with a reduced likelihood of MDD even after adjustment for a series of covariates. Although exploratory, these findings show that specific gut microbiota signatures overexpressing Lachnoclostridium and interacting with biological aging could modulate the liability for MDD.

Understanding dropout and non-participation in follow-up evaluation for the benefit of patients and research: evidence from a longitudinal observational study on patients with eating disorders.

Treatment outcomes in eating disorders (EDs) are still an open field for clinicians and researchers. Besides difficulties in egosyntonic-linked treatment engagements, dropout is one of the most crucial elements that cause a reduction in the treatment efficacy. Thus, the aim of this study is to evaluate factors that could contribute to high dropout rates and non-participation in follow-up evaluation in patients with ED. This study used a large sample of patients from a specialized ED ward and day hospital (DH). A sample of 428 individuals was recruited for this study. Psychological and demographic data were collected at the time of hospitalization and discharge from the facilities. These data were used to explore a possible link between dropout and follow-up non-participation. Specially, the random forest was used to rank demographic and psychological features in importance and evaluate the top results with regression analyses for statistical significance. A dropout rate of 12.14% during inpatient and DH treatment was found. Anger-hostility and general psychopathology were found to be predictors of dropout during treatment, while the duration of the hospitalization predicted non-participation at the six-month follow-up. Specific psychological features should be considered before and during treatments for patients with EDs to reduce dropout rates. The duration of the hospitalization should also be evaluated as a relevant healthcare element that could affect engagement and, accordingly, outcome.

Preparing for the next pandemic by understanding the impact of COVID-19 mitigation measures on patients with eating Disorders: observations from an inpatient setting.

OBJECTIVE: The COVID-19 pandemic overwhelmed eating disorder (ED) services worldwide. Data suggests a worsening of psychopathology and an increased request for specialised treatments. Still, the studies are mostly based on experimental protocols with underpowered short-term opportunistic experimental designs. Thus, this study aims to assess the clinical and psychological differences between patients admitted to a specialised ED Unit before and after the COVID-19 breakout. METHODS: Consecutive patients admitted from June 2014 to February 2022 in a specialised EDs Unit were enrolled. A total sample of 498 individuals was enrolled in this retrospective study, collecting demographic and psychopathological data at admission. RESULTS: An increase in the admission of patients with anorexia nervosa has been reported, with lower age and higher levels of specific and general psychopathology, especially linked to body uneasiness. CONCLUSIONS: Results are put into the context of the preparation for the next pandemic that may require similar mitigation measures as COVID-19 to ensure the impact on existing and new patients. Covering an extended period with validated tools, our results might help psychiatric services to reassess their treatment pathways after the pandemic, helping clinicians to delineate future treatment interventions.KEYPOINTSAfter the COVID-19 breakdown, there was an increase in the admission of patients with anorexia nervosa to specialised services.More severe psychopathology was not accompanied by lower body mass index.Specialised eating disorders services should face sudden changes in patients' requests for treatment.Understanding the impact of the Covid-19 pandemic and the resulting mitigation measures taken can lead to better preparations for the next pandemic.

Validation of the generalized anxiety disorder screener (GAD-7) in Cypriot pregnant and postpartum women.

BACKGROUND: Anxiety is increasingly acknowledged as a common mental health issue during the perinatal period. Its prevalence as well as the associated adverse effects constitute screening imperative. This study evaluates the psychometric properties and underlying factor structures of a Greek version of GAD-7 among pregnant and postpartum women (up to 6 months) in Cyprus. METHODS: This study was conducted from June to December 2020. A total of 457 Cypriot women in the perinatal period (222 pregnant and 235 postpartum) were surveyed. The assessment included anxiety (GAD-7) and depression (EPDS), and psychosocial factors related with anxiety. The internal consistency and factor structure of GAD-7 were evaluated using reliability coefficients, Cronbach's Alpha and McDonald's Omega, and factor analysis, both Exploratory as well as Confirmatory. RESULTS: GAD-7 demonstrated good internal consistency (α = 0.907; Ω = 0.909). Horn's parallel analysis indicated a single factor as the most appropriate. CFA using the standard ML method indicated a good model fit, χ2 = 21.207, p = 0.096; CFI = 0.999; SRMR = 0.027. More studies are needed to determinate the cut-off point and the maximisation of the scale's sensitivity and specificity in pregnant and postpartum Greek Cypriot women. CONCLUSIONS: GAD-7 is a valid and reliable measure and healthcare professionals should utilize GAD-7 as a standard instrument for the screening of anxiety symptoms in pregnant and postpartum Greek Cypriot women.

Experiences, concerns, and needs of pregnant and postpartum women during the Covid-19 pandemic in Cyprus: a cross-sectional study.

BACKGROUND: The current COVID-19 pandemic is a unique stressor with potentially challenging and negative consequences on the experiences of pregnant and postpartum women. International literature highlights the pandemic's negative impact on women's perinatal experiences. This is the first study in the scientific literature reporting on the impact of the COVID-19 pandemic, on the perinatal experiences of a large sample of women living in Cyprus. AIM: To examine the impact of the COVID-19 pandemic on the experiences, concerns and needs of pregnant and postpartum women in Cyprus. METHOD: The cross-sectional study was conducted from July 2020 to January 2021. A total of 695 women, 355 pregnant and 340 postpartum women (with infants up to 6 months of age), residing in Cyprus were surveyed. RESULTS: The great majority of the participants (80.9%) perceived the impact of the COVID-19 pandemic on their life as negative. The greatest sources of stress were identified and quantified for their impact on the participants. Our findings indicate that 74.1% of the pregnant women were concerned about changes due to COVID-19 measures impacting the presence of their family at the time of delivery, 57.2% about their newborn's health, and 43.1% about changes related to perinatal care. Postpartum women's concerns were mainly related to the welfare and health of their child (70.3%), whilst half of them (49.1%) expressed concerns about how they were going to care for their baby because of pandemic-related changes. Qualitative data revealed emerging themes as the basis of the pregnant and postpartum women's concerns and needs. CONCLUSIONS: The COVID-19 pandemic and the associated imposed measures and restrictions had adverse effects on pregnant and postpartum women's perinatal experiences in Cyprus. The women's concerns emphasized the need for the development of specialized, evidenced-based support systems which are essential particularly in pandemic-like situations, when pregnant and postpartum women are more vulnerable to isolation.

Impulsive behaviors and clinical outcomes following a flexible intensive inpatient treatment for eating disorders: findings from an observational study.

PURPOSE: The aim of the study was to assess the differences between impulsive and non-impulsive patients in response to a multidisciplinary intensive inpatient treatment for eating disorders (EDs). METHODS: 320 patients with EDs were consecutively recruited in an eating disorders unit (EDU). They were assessed by clinical interviews and self-reported questionnaires. The treatment was characterized by a patient-centric approach and included both an intensive and comprehensive standardized multidisciplinary program based on cognitive-behavioral therapy and a flexible and personalized component according to the needs and the history of each patient. RESULTS: Impulsive ED patients showed greater improvement in specific psychopathological areas, in particular: interpersonal sensitivity of Symptom Checklist-90 (SCL-90) (p = 0.007); Eating Disorder Examination Questionnaire (EDE-Q) Global Score (p = 0.009), EDE-Q eating concern (p < 0.001) and EDE-Q shape concern (p = 0.025). The two groups also showed a different pattern on the Body Uneasiness Test, with impulsive patients uniquely showing improvement on Global Severity Index (p = 0.006), body image concern (p = 0.008), compulsive self monitoring (p = 0.002), and weight phobia (p = 0.037). DISCUSSION: Results support the hypothesis that patients with impulsive behaviors might benefit from treatments characterized by a standardized cognitive behavioral therapy implemented by third-wave interventions according to each patient's clinical profile. Personalized treatment approaches could be an answer to the complexity of ED, addressing individual psychopathology. Further studies are needed to confirm these preliminary findings. LEVEL OF EVIDENCE: III, cohort or case-control analytic studies.

Relation between vitamin D and impulse behaviours in patients with eating disorder: a pilot observational study.

OBJECTIVE: There is growing evidence that vitamin D levels have a role not only in bone health and energy metabolism, but also for supporting nervous system and brain functions, including impulsivity. Impulsive behaviours are considered characteristics of great relevance in patients with Eating Disorders (ED) both for the course of the illness and for the treatment. The aim of this study is to examine the relationship between impulsive behaviours and vitamin D in patients with ED. METHOD: 236 patients with a diagnosis of ED, consecutively recruited at an ED ward between 2014 and 2018, were enrolled. Patients were classified as impulsive or non-impulsive based on the presence of clinically relevant impulsive behaviours. RESULTS: Impulsive patients were found to have statistically significant lower levels of vitamin D than non-impulsive (p = .007). A threshold value of 20.4 ng/ml for discriminating impulsive from non-impulsive patients was found. DISCUSSION: This hypothesis generating study partially confirmed a relationship between vitamin D deficiency and impulsive behaviours in ED spectrum mediated by body weight, even if results were not confirmed after corrected by obesity. No definitive conclusion may be taken on whether the effect is reduced due to the loss of power. Future directions are discussed.

Rapid on-site evaluation with the Hemacolor rapid staining method of medical thoracoscopy biopsy specimens for the management of pleural disease.

BACKGROUND AND OBJECTIVE: Medical thoracoscopy (MT) is useful for the management of pleural disease. Rapid on-site evaluation (ROSE) of transbronchial needle aspirates proved to be useful during bronchoscopy. We aimed to evaluate the diagnostic performance of ROSE of MT biopsy specimens and thoracoscopists' impression of the macroscopic appearance and assess the intermodality agreement between ROSE and final histopathologic diagnosis. METHODS: Sixty two patients with exudative pleural effusions further investigated with MT were enrolled. MT was performed under local anaesthesia and conscious sedation, using the rigid pleuroscope. ROSE with the Hemacolor rapid staining method of the biopsy specimens was performed. Thoracoscopists' impression of the macroscopic appearance was recorded. The final diagnosis was established following histopathological examination. RESULTS: Thoracoscopic pleural biopsies were diagnosed in 61 patients (98.4%). Group A (n = 25) consisted of patients with malignancy and group B (n = 37) with benign disorders. Area under the curve of ROSE for the diagnosis of malignancy was 0.86 (95% CI: 0.76-0.96, P < 0.001), with a sensitivity of 79.17%, specificity of 94.59%, diagnostic accuracy of 88.5%, positive predictive value of 90.5% and negative predictive value of 87.5%. Intermodality agreement between ROSE and histopathology was good (κ ± SE = 0.615 ± 0.084, P < 0.001). Area under the curve of the thoracoscopists' impression of macroscopic appearance was 0.72 (95% CI: 0.58-0.85, P = 0.001), with a sensitivity of 100%, specificity of 44.7%, positive predictive value of 53.33% and negative predictive value of 100%. CONCLUSION: Rapid on-site evaluation during MT was found to have high accuracy for predicting malignancy. ROSE can provide the thoracoscopist with an on-site preliminary diagnosis, especially in cases with inconclusive macroscopic appearance.

Effects of Four Weeks of In-Season Pre-Workout Supplementation on Performance, Body Composition, Muscle Damage, and Health-Related Markers in Basketball Players: A Randomized Controlled Study.

This randomized, double-blinded, experimental study investigated the effects of a four-week daily pre-workout supplementation (200 mg caffeine, 3.3 g creatine monohydrate, 3.2 g ß-alanine, 6 g citrulline malate, and 5 g BCAA) vs. placebo (isocaloric maltodextrin) on anaerobic (jumping, sprinting, agility, and the running-based anaerobic sprint test: RAST) and aerobic (Yo-Yo intermittent recovery test level 1) performance, as well as on body composition and selective muscle damage/health-related blood markers in well-trained basketball players during the in-season period. Eighteen basketball players (age: 24.4 ± 6.3 years, height: 185.7 ± 8.0 cm, weight: 85.7 ± 12.8 kg, body fat: 16.5 ± 4.2%) were randomly assigned into two groups: pre-workout supplement (PWS, n = 10) or placebo (PL, n = 8). PWS consumption increased aerobic performance (PWS: 8 ± 6%; PL: -2 ± 6%; p = 0.004) compared to PL. A significant decrease was observed in peak (F = 7.0; p = 0.017), average (F = 10.7; p = 0.005), and minimum power (F = 5.1; p = 0.039) following 4 weeks of supplementation in both groups. No other significant changes were observed between groups (p > 0.05). In conclusion, the consumption of the current PWS over a four-week period appears to positively influence the aerobic performance of well-trained basketball players during the in-season period. However, it does not appear to mitigate the observed decline in anaerobic power, nor does it affect performance in jumping, sprinting, and agility, or alter body composition or selective muscle damage/health-related blood markers.

Perspectives of European Patient Advocacy Groups on Volunteer Registries and Vaccine Trials: VACCELERATE Survey Study.

BACKGROUND: The VACCELERATE Pan-European Scientific network aims to strengthen the foundation of vaccine trial research across Europe by following the principles of equity, inclusion, and diversity. The VACCELERATE Volunteer Registry network provides access to vaccine trial sites across the European region and supports a sustainable volunteer platform for identifying potential participants for forthcoming vaccine clinical research. OBJECTIVE: The aim of this study was to approach members of patient advocacy groups (PAGs) across Europe to assess their willingness to register for the VACCELERATE Volunteer Registry and their perspectives related to participating in vaccine trials. METHODS: In an effort to understand how to increase recruitment for the VACCELERATE Volunteer Registry, a standardized survey was developed in English and translated into 8 different languages (Dutch, English, French, German, Greek, Italian, Spanish, and Swedish) by the respective National Coordinator team. The online, anonymous survey was circulated, from March 2022 to May 2022, to PAGs across 10 European countries (Belgium, Cyprus, Denmark, France, Germany, Greece, Ireland, Italy, Spain, and Sweden) to share with their members. The questionnaire constituted of multiple choice and open-ended questions evaluating information regarding participants' perceptions on participating in vaccine trials and their willingness to become involved in the VACCELERATE Volunteer Registry. RESULTS: In total, 520 responses were collected and analyzed. The PAG members reported that the principal criteria influencing their decision to participate in clinical trials overall are (1) the risks involved, (2) the benefits that will be gained from their potential participation, and (3) the quality and quantity of information provided regarding the trial. The survey revealed that, out of the 520 respondents, 133 individuals across all age groups were "positive" toward registering in the VACCELERATE Volunteer Registry, with an additional 47 individuals reporting being "very positive." Respondents from Northern European countries were 1.725 (95% CI 1.206-2.468) times more likely to be willing to participate in the VACCELERATE Volunteer Registry than respondents from Southern European countries. CONCLUSIONS: Factors discouraging participants from joining vaccine trial registries or clinical trials primarily include concerns of the safety of novel vaccines and a lack of trust in those involved in vaccine development. These outcomes aid in identifying issues and setbacks in present registries, providing the VACCELERATE network with feedback on how to potentially increase participation and enrollment in trials across Europe. Development of European health communication strategies among diverse public communities, especially via PAGs, is the key for increasing patients' willingness to participate in clinical studies.

Attachment, Resilience and Life Satisfaction of University Students in Cyprus after the Fourth Wave of COVID-19.

The COVID-19 pandemic has given rise to a large-scale crisis that has also impacted the well-being and, more specifically, the life satisfaction of university students. Factors such as attachment dimensions and psychological resilience can provide us with a better understanding of students' life satisfaction levels during the recent pandemic. While previous literature has revealed a significant association between attachment dimensions, resilience, and life satisfaction, very few studies have attempted to address a more complex relationship among all three variables for university students, and even fewer have explored this topic during the COVID-19 pandemic. Therefore, the aim of the current study was to investigate the impact of attachment dimensions on university students' life satisfaction after the fourth wave of COVID-19 in Cyprus, with a focus on the mediating role of psychological resilience. The sample comprised 780 university students, consisting of 323 men and 457 women, aged between 18 and 61 years. Participants were recruited electronically, and after being directed to Google Forms, they completed the ECR-R for their attachment dimensions, the RES for psychological resilience, and the SWLS for life satisfaction. The results indicated significant correlations between attachment dimensions, psychological resilience, and life satisfaction. Notably, psychological resilience was found to partially mediate the relationship between attachment anxiety, as well as attachment avoidance, and life satisfaction. Specifically, attachment anxiety and avoidance negatively affected life satisfaction, partially due to lower levels of psychological resilience. These findings are discussed in relation to the existing literature, and implications for practice are provided.

Dynamic monitoring of PD-L1 and Ki67 in circulating tumor cells of metastatic non-small cell lung cancer patients treated with pembrolizumab.

Programmed cell death protein ligand-1 (PD-L1) expression in non-small cell lung cancer (NSCLC) tumors guides treatment selection. PD-L1 expression in circulating tumor cells (CTCs) may provide further information. We have explored PD-L1 and marker of proliferation Ki-67 (Ki67; also known as MKI67) in CTCs in longitudinal samples of 47 advanced NSCLC patients receiving pembrolizumab. A triple immunofluorescence, against cytokeratin, PD-L1, and Ki67, was performed on peripheral blood mononuclear cells, at baseline, post-first cycle, post-third, and primary resistance (PMR). Patients displaying PMR (progression at first evaluation) were classified as progressive disease (PD) and those with clinical benefit as disease control (DC). CTCs were categorized as PD-L1high/low/medium/negative and Ki67+ or Ki67- . CTC evaluation revealed a significant increase in the PD-L1low CTC rate at PMR compared to baseline (2.5% at baseline vs. 36.5% at PMR), whereas a reduction in the PD-L1high CTC rate was observed (31.5% vs. 0%, respectively). Investigation of CTC status between PD and DC patients showed that PD patients more frequently increased total and PD-L1low CTCs after first cycle compared to DC (83% of PD vs. 37% of DC and 67% of PD vs. 8% of DC, respectively). Progression-free survival (PFS) was longer in patients with decreased total and PD-L1low CTCs after first cycle compared to those with increased CTCs (median PFS: not reached vs. 2 months). PD-L1+ patients presenting a high Ki67 index (% Ki67+ CTCs > 30%) before treatment had a shorter PFS compared to those with a low Ki67 (≤ 30%), and overall survival (OS) was shorter in PD-L1+ patients harboring Ki67+ CTCs compared to those not presenting (median OS: 11.8 months vs. 33.1 months, respectively). In sequential samples of patients with a durable benefit, a low Ki67 index was observed. Our results suggest that monitoring PD-L1 and Ki67 expression in CTCs of NSCLC patients treated with pembrolizumab may be predictive for pembrolizumab efficacy.

Fecal Microbiota and Associated Volatile Organic Compounds Distinguishing No-Adenoma from High-Risk Colon Adenoma Adults.

Microbiota and the metabolites they produce within the large intestine interact with the host epithelia under the influence of a range of host-derived metabolic, immune, and homeostatic factors. This complex host-microbe interaction affects intestinal tumorigenesis, but established microbial or metabolite profiles predicting colorectal cancer (CRC) risk are missing. Here, we aimed to identify fecal bacteria, volatile organic compounds (VOC), and their associations that distinguish healthy (non-adenoma, NA) from CRC prone (high-risk adenoma, HRA) individuals. Analyzing fecal samples obtained from 117 participants ≥15 days past routine colonoscopy, we highlight the higher abundance of Proteobacteria and Parabacteroides distasonis, and the lower abundance of Lachnospiraceae species, Roseburia faecis, Blautia luti, Fusicatenibacter saccharivorans, Eubacterium rectale, and Phascolarctobacterium faecium in the samples of HRA individuals. Volatolomic analysis of samples from 28 participants revealed a higher concentration of five compounds in the feces of HRA individuals, isobutyric acid, methyl butyrate, methyl propionate, 2-hexanone, and 2-pentanone. We used binomial logistic regression modeling, revealing 68 and 96 fecal bacteria-VOC associations at the family and genus level, respectively, that distinguish NA from HRA endpoints. For example, isobutyric acid associations with Lachnospiraceae incertae sedis and Bacteroides genera exhibit positive and negative regression lines for NA and HRA endpoints, respectively. However, the same chemical associates with Coprococcus and Colinsella genera exhibit the reverse regression line trends. Thus, fecal microbiota and VOC profiles and their associations in NA versus HRA individuals indicate the significance of multiple levels of analysis towards the identification of testable CRC risk biomarkers.

Exercise and Occupational Stress among Firefighters.

The aim of our study was to evaluate the potential association between physical activity and occupational stress among firefighters. Data were collected from Cypriot firefighters through a web-based battery of internationally validated questionnaires completed anonymously (COPSOQ, DASS). A total of 430 firefighters (response rate 68%) completed the survey (age range: 21-60 years). More than half of the firefighters (54%) reported either no or minimal physical activity. A total of 11% of firefighters reported moderate to extremely severe stress based on the DASS-S scale. Using multivariable-adjusted logistic regression models, we showed that firefighters who exercised had 50% lower risk of occupational stress, and using a categorical model, we found that every hour per week of increased physical activity among firefighters was associated with 16% lower risk of occupational stress after adjusting for age, education, smoking, and body mass index (OR = 1.16; p = 0.05). In addition, our findings suggest an inverse dose-response relationship between physical activity and occupational stress among firefighters. Physical activity appears to be inversely associated with occupational stress and serves as an important mitigating factor of occupational stress in firefighters. Further research is warranted to evaluate the potential effect of exercise interventions on occupational stress, and the overall mental health of firefighters and other occupational groups.

Colon Cancer: From Epidemiology to Prevention.

Colorectal cancer (CRC) is one of the most prevalent cancers affecting humans, with a complex genetic and environmental aetiology. Unlike cancers with known environmental, heritable, or sex-linked causes, sporadic CRC is hard to foresee and has no molecular biomarkers of risk in clinical use. One in twenty CRC cases presents with an established heritable component. The remaining cases are sporadic and associated with partially obscure genetic, epigenetic, regenerative, microbiological, dietary, and lifestyle factors. To tackle this complexity, we should improve the practice of colonoscopy, which is recommended uniformly beyond a certain age, to include an assessment of biomarkers indicative of individual CRC risk. Ideally, such biomarkers will be causal to the disease and potentially modifiable upon dietary or therapeutic interventions. Multi-omics analysis, including transcriptional, epigenetic as well as metagenomic, and metabolomic profiles, are urgently required to provide data for risk analyses. The aim of this article is to provide a perspective on the multifactorial derailment of homeostasis leading to the initiation of CRC, which may be explored via multi-omics and Gut-on-Chip analysis to identify much-needed predictive biomarkers.

Bifidobacterium Is Enriched in Gut Microbiome of Kashmiri Women with Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is a very common endocrine condition in women in India. Gut microbiome alterations were shown to be involved in PCOS, yet it is remarkably understudied in Indian women who have a higher incidence of PCOS as compared to other ethnic populations. During the regional PCOS screening program among young women, we recruited 19 drug naive women with PCOS and 20 control women at the Sher-i-Kashmir Institute of Medical Sciences, Kashmir, North India. We profiled the gut microbiome in faecal samples by 16S rRNA sequencing and included 40/58 operational taxonomic units (OTUs) detected in at least 1/3 of the subjects with relative abundance (RA) ≥ 0.1%. We compared the RAs at a family/genus level in PCOS/non-PCOS groups and their correlation with 33 metabolic and hormonal factors, and corrected for multiple testing, while taking the variation in day of menstrual cycle at sample collection, age and BMI into account. Five genera were significantly enriched in PCOS cases: Sarcina, Megasphaera, and previously reported for PCOS Bifidobacterium, Collinsella and Paraprevotella confirmed by different statistical models. At the family level, the relative abundance of Bifidobacteriaceae was enriched, whereas Peptococcaceae was decreased among cases. We observed increased relative abundance of Collinsella and Paraprevotella with higher fasting blood glucose levels, and Paraprevotella and Alkalibacterium with larger hip, waist circumference, weight, and Peptococcaceae with lower prolactin levels. We also detected a novel association between Eubacterium and follicle-stimulating hormone levels and between Bifidobacterium and alkaline phosphatase, independently of the BMI of the participants. Our report supports that there is a relationship between gut microbiome composition and PCOS with links to specific reproductive health metabolic and hormonal predictors in Indian women.

A systematic review of miRNAs as biomarkers for chemotherapy-induced cardiotoxicity in breast cancer patients reveals potentially clinically informative panels as well as key challenges in miRNA research.

Breast cancer patients are at a particularly high risk of cardiotoxicity from chemotherapy having a detrimental effect on quality-of-life parameters and increasing the risk of mortality. Prognostic biomarkers would allow the management of therapies to mitigate the risks of cardiotoxicity in vulnerable patients and a key potential candidate for such biomarkers are microRNAs (miRNA). miRNAs are post-transcriptional regulators of gene expression which can also be released into the circulatory system and have been associated with the progression of many chronic diseases including many types of cancer. In this review, the evidence for the potential application of miRNAs as biomarkers for chemotherapy-induced cardiotoxicity (CIC) in breast cancer patientsis evaluated and a simple meta-analysis is performed to confirm the replication status of each reported miRNA. Further selection of miRNAs is performed by reviewing the reported associations of each miRNA with other cardiovascular conditions. Based on this research, the most representative panels targeting specific chemotherapy agents and treatment regimens are suggested, that contain several informative miRNAs, including both general markers of cardiac damage as well as those for the specific cancer treatments.

Montreal Cognitive Assessment in a Greek sample of patients with multiple sclerosis: A validation study.

The Montreal Cognitive Assessment (MoCA) is a brief cognitive instrument for the measurement of dementia. The aim of the present study was to measure the sensitivity of this test in a group of Greek speaking participants diagnosed with multiple sclerosis. 40 MS participants complaining for cognitive dysfunction were matched in age and education to 490 healthy participants. The MoCA test and a neuropsychological test battery were administered to both groups. The MoCA test was found to differentiate the MS from the controls (U = 3761.00, p < .001) and it was correlated with all neuropsychological tests (digit span: r = 0.454, p < .0001; phonemic verbal fluency: r = 0.390, p < .0001; semantic verbal fluency: r = 0.319, p < .0001; Color Trails Test 1 (CTT1): r = -.256, p < .0001; Color Trails Test 2 (CTT2): r = -.321, p < .0001). Multiple regression analysis showed that 10.3% of the variation in the MoCA score was accounted for by the Expanded Disability Status Scale (EDSS) total score. Also, the test showed high discriminant validity (optimal screening cut off point 25, sensitivity 0.68, specificity 0.89). MoCA is a sensitive test to differentiate cognitive impairment in Greek speaking MS participants from healthy controls. Further research is needed to use it in larger clinical samples and in different subtypes of the disease.

An acoustic and auditory analysis of vocants in infants with cochlear implants.

INTRODUCTION: The duration of the nuclei is a crucial factor for the shift of prelexical to mature speech, since control of duration is closely related with improved speech intelligibility. OBJECTIVES: This work records the suprasegmental feature of duration in infants with normal hearing (NH) compared to those with cochlear implants (CI) based on vocant productions (quasivowels and full vowels). MATERINALS AND METHODS: In this longitudinal study, 102 vocant productions were analyzed from cases of congenitally hearing-impaired infants (implantation ages 1:4 and 1:11 years; post-implant ages 0:6 months and 1:3 years) who were matched with three NH infants of similar hearing experience (ages 0:8-0:11 months). Current methodology analyzes vocants using a combination of acoustical and auditory analyses. Vegetative data or reflexive sounds were excluded. Participants had had unknown deafness etiology and no other disabilities. Duration was measured using wideband spectrographic analysis, from voice onset to the loss of audible signal and the decrease of higher formant's energy. RESULTS: The results showed that the mean vocant duration of young CI users was longer, compared to hearing matched peers during the first six months after cochlear implantation. CONCLUSIONS: This recorded weakness for CI users' speech production is a challenge for future work in speech processing strategies. This is the first study measuring production of vocants during the pre-linguistic stage in CI recipients.

Outcomes of 556 consecutive patients with stage I-III colon cancer managed in a single center over 10 years.

BACKGROUND: The Bank of Cyprus Oncology Center is the largest cancer center in Cyprus, providing standalone oncology services to a population of just under a million. METHODS: The aim of the study was to calculate disease-free survival (DFS) and overall survival (OS) for consecutive patients with stage I-III colon cancer over a 10-year period, by collecting retrospective data from patients' medical charts. RESULTS: We identified 556 patients with a median age at diagnosis of 67 (range 18-88). The majority of them were male (60%). Just over half of stage II patients received chemotherapy: capecitabine (44%) and FOLFOX/CapeOx (7%). Treatment administered in stage III was as follows: CapeOx (48%); FOLFOX (28%); capecitabine (12%); 5-fluorouracil (4%); and 8% received no treatment. DFS at 5 years was: stage I 90%; stage II 85%; and stage III 69%. Cancer-specific OS at 5 years was: stage I 94%; stage II 93%; and stage III 81%. Favorable outcomes were also maintained at 10 years (stage I 94%; stage II 84%; and stage III 70%). On multivariate analysis, only stage was statistically significant as a prognostic factor, whereas high-risk features (pT4±pN2), disease location (right vs. left), and age >70 years old did not reach statistical significance. CONCLUSIONS: Despite our country's fragmented healthcare system, with multiple referring surgeons from the private and public sectors, the outcomes achieved were highly consistent with those published in the international literature. This can be attributed to optimal multidisciplinary management and follow-up care.
