The intestinal microbiota consists of numerous microbial species that collectively interact with the host, playing a crucial role in health and disease. Colorectal cancer is well-known to be related to dysbiotic alterations in intestinal microbiota. It is evident that the microbiota is significantly affected by colorectal surgery in combination with the various perioperative interventions, mainly mechanical bowel preparation and antibiotic prophylaxis. The altered postoperative composition of intestinal microbiota could lead to an enhanced virulence, proliferation of pathogens, and diminishment of beneficial microorganisms resulting in severe complications including anastomotic leakage and surgical site infections. Moreover, the intestinal microbiota could be utilized as a possible biomarker in predicting long-term outcomes after surgical CRC treatment. Understanding the underlying mechanisms of these interactions will further support the establishment of genomic mapping of intestinal microbiota in the management of patients undergoing CRC surgery.

Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency.Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior segmental branches, the way they form the right hepatic duct, and the main variations of their drainage pattern.Results. The anatomy of the right hepatic duct was typical in 65.75% of samples. Ectopic drainage of the right anterior duct into the common hepatic duct was found in 15.07% and triple confluence in 9.59%. Ectopic drainage of the right posterior duct into the common hepatic duct was discovered in 2.74% and ectopic drainage of the right posterior duct into the left hepatic duct in 4.11%. Ectopic drainage of the right anterior duct into the left hepatic ductal system and ectopic drainage of the right posterior duct into the cystic duct was found in 1.37%.Conclusion. The branching pattern of the right hepatic duct was atypical in 34.25% of cases. Thus, knowledge of the anatomical variations of the extrahepatic bile ducts is important in many surgical cases.

Background: There is increasing interest in the role of EEG in neurorehabilitation. We primarily aimed to identify the knowledge base through highly influential studies. Our secondary aims were to imprint the relevant thematic hotspots, research trends, and social networks within the scientific community. Methods: We performed an electronic search in Scopus, looking for studies reporting on rehabilitation in patients with neurological disabilities. We used the most influential papers to outline the knowledge base and carried out a word co-occurrence analysis to identify the research hotspots. We also used depicted collaboration networks between universities, authors, and countries after analyzing the cocitations. The results were presented in summary tables, plots, and maps. Finally, a content review based on the top-20 most cited articles completed our study. Results: Our current bibliometric study was based on 874 records from 420 sources. There was vivid research interest in EEG use for neurorehabilitation, with an annual growth rate as high as 14.3%. The most influential paper was the study titled “Brain-computer interfaces, a review” by L.F. Nicolas-Alfonso and J. Gomez-Gill, with 997 citations, followed by “Brain-computer interfaces in neurological rehabilitation” by J. Daly and J.R. Wolpaw (708 citations). The US, Italy, and Germany were among the most productive countries. The research hotspots shifted with time from the use of functional magnetic imaging to EEG-based brain–machine interface, motor imagery, and deep learning. Conclusions: EEG constitutes the most significant input in brain–computer interfaces (BCIs) and can be successfully used in the neurorehabilitation of patients with stroke symptoms, amyotrophic lateral sclerosis, and traumatic brain and spinal injuries. EEG-based BCI facilitates the training, communication, and control of wheelchair and exoskeletons. However, research is limited to specific scientific groups from developed countries. Evidence is expected to change with the broader availability of BCI and improvement in EEG-filtering algorithms.

Musculoskeletal disorders represent a common reason for the general population to seek care from the health services.1,2 Standardised questionnaires are among the widely accepted methods for collection and analysis of relevant data. The standardised questionnaires for the analysis of musculoskeletal symptoms (Nordic Musculoskeletal Questionnaires, NMQs),3 the general form and the specific low back and neck/shoulder questionnaires, have been extensively used as a screening instrument in epidemiological studies across Europe and all over the world.4,5 The lack of specific questionnaires that are validated in the Greek language was the main reason for this study of translation and validation of the general NMQ into Greek.

Background Critical illness polyneuropathy or myopathy is a severe disorder that may adversely affect patients in the intensive care unit, resulting in reduced mobilization, decline in muscle mass, and prolonged recovery periods. Objective To examine whether the application of trans-cutaneous electrical neuromuscular stimulation (TENMS) reduces the incidence or severity of myopathy related to critical illness in intensive care unit patients. Methods A total of 80 patients aged 18 years or older with an intensive care unit stay of 96 hours or more and receipt of mechanical ventilation for 96 hours or more were initially enrolled in a prospective, open-label randomized controlled trial in a university hospital. Patients received either conventional physical therapy alone (control group) or conventional physical therapy plus TENMS (TENMS group) for 10 days. Myopathy was assessed histologically (by needle biopsy of the quadriceps muscles) on the 4th and 14th days of the intensive care unit stay. Results Of the 68 patients who completed the study, 27 (40%) had myopathy on the 14th day: 11 patients in the TENMS group (9 mild, 1 moderate, and 1 severe) and 16 patients in the control group (13 mild, 2 moderate, and 1 severe). Patients who progressed from mild to moderate or severe myopathy between the 4th and 14th days had significantly lower body mass index (P = .001) and longer time periods with inadequate nutrition (P = .049) compared with the other patients. Mean (SD) Rankin scale scores at 6 months were 3.2 (1.8) and 3.8 (2.1) in the TENMS and control groups, respectively (P = .09). Conclusion TENMS had no significant impact on myopathy in the critically ill patients in this study.

Objectives: The study aims at exploring the feelings and the experience of fathers about their wife/partner’s delivery. Background: During the last decades birth attendance by fathers is a common phenomenon across many countries. Fathers’ birth attendance may evoke both positive and negative feelings. Methodology: The study was conducted in a city of Northern Greece. The sample consisted of 417 fathers whose wife/partner had given birth during the previous one week to one year. Data were collected using the Kuopio Instrument for Fathers (KIF). Results: Father’s feelings about their wife or partner were very positive as nearly all (82.1%) of the participants were proud to become fathers and agree that they felt love and were grateful to their wife/partner. However, half of the fathers felt anxious and nervous. 40.7% quite agree that the staff was very professional, that they trusted the staff (45%) and that they were grateful to the staff (38.8%). There is correlation between the “feelings related to the wife/partner” and education (r=0.156, p=0.0047), “being afraid during the preparatory visit at the obstetric hospital” (r=-0.238, p=0.009), and “anxiety during the preparatory visit” (r=0.295 p=0.005). The subscale “feelings related to the environment and staff” correlates with “usefulness of preparatory visit” (r=-0.223, p=0.004) and the subscale of “experiences related to delivery” correlates with “usefulness of preparatory visit” (r=-0.357, p=0.001). Conclusions: Our results support the findings of previous studies, which indicated that birth attendance by fathers has evoked positive feelings about their wife/partner, the delivery, the staff and the hospital environment.
