Major depressive disorder (MDD) and generalized anxiety disorder (GAD) are severe and difficult-to-treat psychiatric illnesses with high rates of comorbidity. Although both disorders are treated with serotonergic based psychotropic agents, little is known on the influence of the serotonergic neurotransmitter system on the occurrence of comorbid GAD when clinically depressed. To investigate this poorly understood clinical question, we examined the involvement of frontolimbic post-synaptic 5-HT2A receptors in 20 medication-resistant depressed (MRD) patients with half of them diagnosed with comorbid GAD with 123I-5-I-R91150 SPECT. To explore whether 5-HT2A receptor-binding indices (BI) associated with comorbid GAD could be related to distinct psychopathological symptoms, all were assessed with the symptom Checklist-90-Revised (SCL-90-R). MRD patients with comorbid GAD displayed significantly higher 5-HT2A receptor BI in the hippocampal-amygdala complex, compared to MRD patients without GAD. Correlation analyses revealed that the 5-HT2A receptor BI in these areas were significantly related to the SCL-90-R subscale hostility (HOS), especially for those MRD patients with comorbid GAD. Comorbid MRD-GAD may be characterized with increased hippocampal-amygdala 5-HT2A receptor BI which could represent enhanced levels in hostility in such kinds of patients. Adapted psychotherapeutic interventions may be warranted.

A cohort study analysing phases and outcomes of the learning curve required to master minimally invasive total adventitial resection of the cardia.

Data from 198 consecutive oesophagectomies performed by a single surgeon was collected prospectively. Patients' stratification reflected chronologically and technically the four main phases of the learning curve open surgery (open total adventitial resection of the cardia (TARC), n = 45), hybrid Ivor Lewis oesophagectomy (HILO, n = 50), laparoscopic-thoracoscopic assisted (LTA, n = 56) and totally minimally invasive TARC (TMI TARC, n = 47). Operating time, hospital stay, specimen lymph nodes and resection margins were analysed. Five-year survival was the main long-term outcome measured.

Overall 5-year survival was 45%. Perioperative mortality was 1.5% (n = 3). GSK1904529A mouse Hospital stay was 22 ± 23 days. Specimen lymph node median was 20 (range 15-26). Resection margins were negative (R = 0, American College of Pathologists) in 193 cases (97.4%). Five-year survival in thuld be validated by randomised trials as a standardised anatomical resection for tumours of the oesophagogastric junction.A Gram-stain-negative, long-rod shaped, and facultatively anaerobic bacterium, designated as strain M1T, was isolated from the marine sediment of Jeju Island, South Korea. Strain M1T was found to be catalase- and oxidase-positive, light yellow-pigmented, non-motile, and non-flagellated, growing optimally at 30 °C, pH 7.0, and in the presence of 3% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain M1T belongs to the genus Draconibacterium and is closely related to Draconibacterium orientale FH5T (97.2%), Draconibacterium sediminis JN14CK-3 T (96.5%), "Draconibacterium filum" F2T (96.5%) and Draconibacterium mangrovi GM2-18 T (96.3% sequence similarity). The values for digital DNA-DNA hybridization ranged from 37.6 to 38.3% against D. orientale FH5T, D. sediminis KN14CK-3 T, and D. mangrovi GM2-18 T, clearly indicating that strain M1T represents a distinct species of the genus Draconibacterium. Strain M1T has a 40.0% G + C content estimated by genome sequence, menaquinone 7 as the sole respiratory quinone, C150 anteiso and C150 iso as the major fatty acids, and phosphatidylethanolamine, an unidentified phospholipid, and unidentified lipids as the polar lipids. Based on the polyphasic characteristics, it is suggested that strain M1T be assigned to the genus Draconibacterium as the type strain of a novel species, for which the name Draconibacterium halophilum sp. nov. is proposed. The type strain is M1T (= KCTC 72809 T = VTCC 910107 T).Nocardiosis is a major problem affecting fish that are farmed in seacages as well as freshwater fish; therefore, deciphering the bacteriological features of Nocardia seriolae is crucial. In particular, a number of studies over the past two years have reported the genome sequence of N. seriolae, and a comparative genomics approach is expected to yield valuable information on its epidemiological characteristics. The purpose of this study was to perform whole-genome sequence analysis of N. seriolae MH196537 from the Japanese eel and to investigate the significant differences noted between strains isolated from freshwater fish and marine fish by using Random Forest, a reliable machine learning algorithm. The Pacbio platform was employed to sequence the MH196537 strain, and genomic information from the other 16 strains was used for comparative analyses. All coding sequences of the 17 strains were categorized in RASTtk Sub-systems. The MH196537 strain had one contig, and it shared a high average nucleotide identity (ANI) with the freshwater strains (0.9994 - 0.9999) rather than the seawater strains (0.9985 - 0.9994). Moreover, 22 RASTtk subsystems carried a different number of genes from each N. seriolae. The fatty acids, lipids, and isoprenoids subsystem showed the highest mean decrease in the Gini index of over 1.5. link2 Interestingly, freshwater strains were found to harbor all of the genes for both the mevalonate (MVA) and non-mevalonate pathways (MEP), whereas only the MEP existed in strains from diseased marine fish. Considering the differences in the byproducts of isoprenoids from the different pathways, it is likely that this will affect host-pathogen interactions; therefore, harboring the different pathways for the synthesis of isoprenoids could be an important pathogenic factor of N. seriolae.Bioprospecting sub-explored environments such as Antarctic locations leads to finding out diverse activities, reducing harmful chemical usage that affects both human health and the environment. In this study, ~ 7000 cold-adapted bacterial strains were isolated from samples around Melchior Antarctic Base at 5 °C and more than 13,000 at 15 °C. Out of them, 900 different colony morphotypes were evaluated for antimicrobial production, and 13 isolates demonstrated antibacterial and antifungal activities. One isolate, closely related to Burkholderia gladioli according to 16S rDNA (99.8%), gyrB (99.6%) and Cpn60 (99.4%) gene sequence analysis, showed a consistent, broad antimicrobial spectrum against both pathogenic and phytopathogenic bacteria. Its potent antifungal activity inhibits the growth of various plant pathogenic fungi, whereas it was mainly studied against Penicillium digitatum and Macrophomina phaseolina, the causal agents of blue mould in postharvest fruits and charcoal rot in soybean crops, respectively. The antibacterial compound exhibited low molecular weight ( less then  6000 Da), resistance to lytic enzymes and stability in a broad range of temperature and pHs. Observations of the B. gladioli MB39 antifungal effects over M. phaseolina mycelia by scanning electron microscopy showed alterations in hyphal structures, reduced hyphal extension, and severe cell morphology changes such as cytoplasmic leakage, flattened and empty mycelia. Here we report the isolation and identification of a cold-adapted B. gladioli strain. The results describe the effectiveness of the antarctic strain for bacterial and fungal phytopathogens biocontrol and its potential for crop protection plans.Cyanobacterial communities of three co-located eutrophic sandpit lakes were surveyed during 2016 and 2017 over season and depth using high-throughput DNA sequencing of the 16S rRNA gene. All three lakes were stratified except during April 2017 when the lakes were recovering from a strong mixing event. 16S rRNA gene V4 sequences were parsed into operational taxonomic units (OTUs) at 99% sequence identity. After rarefaction of 139 samples to 25,000 sequences per sample, a combined total of 921,529 partial 16S rRNA gene sequences were identified as cyanobacteria. They were binned into 19,588 unique cyanobacterial OTUs. Of these OTUs, 11,303 were Cyanobium. Filamentous Planktothrix contributed 1537 and colonial Microcystis contributed 265. The remaining 6482 OTUs were considered unclassified. For Planktothrix and Microcystis one OTU accounted for greater than 95% of the total sequences for each genus. However, in both cases the non-dominant OTUs clustered with the dominant OTUs by date, lake, and depth. All Planktothrix OTUs and a single Cyanobium OTU were detected below the oxycline. All other Cyanobium and Microcystis OTUs were detected above the oxycline. link3 The distribution of Cyanobium OTUs between lakes and seasons can be explained by an epidemic-like response where individual OTUs clonally rise from a diverse hypolimnion population when conditions are appropriate. The importance of using 99% identity over the more commonly used 97% is discussed with respect to cyanobacterial community structure. The approach described here can provide another valuable tool for assessing cyanobacterial populations and provide greater insight into the controls of cyanobacterial blooms.

Police work carries the risk of burnout in the form of exhaustion and disengagement from work. Police officers are also exposed to traumatic events and the development of PTSD. The main aim of the cross-sectional study was to determine the mediating role played by rumination in the relationship between burnout and PTSD among police officers. It also examines whether burnout is a significant prognostic factor for PTSD symptoms.

Data were obtained from a sample of 120 police officers. Of these one hundred, mostly men (83%), aged 23-47years (M = 33.06, SD = 5.61), confirmed the experience of traumatic events in connection with their professional work. Three standard measuring tools were used The Posttraumatic Checklist for DSM-5, The Oldenburg Burnout Inventory OBI, and The Event-Related Rumination Inventory.

The introduction of intrusive ruminating as an intermediary variable made the relationship between job burnout and PTSD non-significant, which indicates full mediation. The introduction of deliberate rumination as a mediator weakens the relationship between burnout and PTSD, which indicates partial mediation. It indicates that police officers who are burnout and who additionally tend to ruminate about experienced traumatic events are more likely to PTSD than police officers who are only burned out.

Intervention programs for police officers should focus on strengthening stress management resources in the form of developing deliberate ruminations, thus allowing the experienced situations to be given a new meaning and to allow better coping.

Bakers are at high risk of rhinitis and asthma, but the prevalence of these occupational diseases is not well known in Sub-Saharan Africa. We investigated the prevalence of occupational rhinitis and asthma among industrial bakers in the former province of Katanga.

In a cross-sectional study conducted in eight towns from October 2018 to September 2019, we included 276 male workers from 18 industrial bakeries and 113 male controls (35 butchers and 78 bread sellers), all nonsmokers. Participants replied to a validated questionnaire (European Community of Respiratory Health Survey II), administered face to face, and performed spirometry at the work place. In 15 bakers with symptoms of work-related asthma, records of self-measured peak expiratory flow (PEF) 4 times per day during 4weeks were analyzed by the OASYS (Occupational Asthma System) protocol.

The bakers and controls did not differ by age (32.2 ± 7.3 y vs 32.8 ± 10.3 y). According to the questionnaire, work-related rhinitis and asthma were significantly more prevalent among bakers (31% and 5%, respectively) than among controls (2% and 0%, respectively).
