Representation of Auditory Motion Directions and Sound Source Locations in the Human Planum Temporale

The ability to compute the location and direction of sounds is a crucial perceptual skill to efficiently interact with dynamic environments. How the human brain implements spatial hearing is, however, poorly understood. In our study, we used fMRI to characterize the brain activity of male and female humans listening to sounds moving left, right, up, and down as well as static sounds. Whole-brain univariate results contrasting moving and static sounds varying in their location revealed a robust functional preference for auditory motion in bilateral human planum temporale (hPT). Using independently localized hPT, we show that this region contains information about auditory motion directions and, to a lesser extent, sound source locations. Moreover, hPT showed an axis of motion organization reminiscent of the functional organization of the middle-temporal cortex (hMT+/V5) for vision. Importantly, whereas motion direction and location rely on partially shared pattern geometries in hPT, as demonstrated by successful cross-condition decoding, the responses elicited by static and moving sounds were, however, significantly distinct. Altogether, our results demonstrate that the hPT codes for auditory motion and location but that the underlying neural computation linked to motion processing is more reliable and partially distinct from the one supporting sound source location. SIGNIFICANCE STATEMENT Compared with what we know about visual motion, little is known about how the brain implements spatial hearing. Our study reveals that motion directions and sound source locations can be reliably decoded in the human planum temporale (hPT) and that they rely on partially shared pattern geometries. Our study, therefore, sheds important new light on how computing the location or direction of sounds is implemented in the human auditory cortex by showing that those two computations rely on partially shared neural codes. Furthermore, our results show that the neural representation of moving sounds in hPT follows a “preferred axis of motion” organization, reminiscent of the coding mechanisms typically observed in the occipital middle-temporal cortex (hMT+/V5) region for computing visual motion.
Osteogenesis Imperfecta: Phenotypic and Intraoperative Findings Observed in Patients Treated Surgically at the World Hearing Centre.

OBJECTIVES Osteogenesis imperfecta (OI) is a systemic connective tissue disease that affects many systems and organs. Features of the disease are bone deformities, blue sclerae, and changes in the teeth, all of which may be accompanied by hearing loss. Bone fragility also affects structures of the ear, with half the patients developing changes in the auditory ossicles, which manifest as hearing loss. The most typical malformation affects the stapes, although the site of malformation within the middle ear varies. This study aims to characterize patients with OI who underwent surgery due to hearing loss and to find factors that affect the hearing results. MATERIALS AND METHODS This study presents an analysis of phenotypic and intraoperative changes among 20 patients with OI, treated surgically for hearing loss. RESULTS Hearing loss typically affects type I patients with OI. The most common changes concern stapes footplate, arms, and tympanic cavity lining. During reoperations, osseous regrowth was typically detected. CONCLUSION The greater the changes induced systemically by OI, the greater the risk of significant malformations in the middle ear. Patients with OI are at an increased risk of needing revision surgery and of suffering intraoperative complications such as bleeding, which hinders safe completion of the procedure.
The impact of social networks and APOE ε4 on dementia among older adults: tests of possible interactions

Abstract Objectives: Emerging evidence suggests that social networks may protect against the development of dementia among older adults. In this study we analysed the association between social networks, the apolipoprotein E (APOE) ε4 allele, and dementia. We also investigated whether there were gender-specific patterns in this respect. Method: The analyses used population-based longitudinal data from Gothenburg, Sweden: the H70 Birth Cohort Study and the Prospective Population Study on Women (PPSW). A total of 580 individuals born in 1930 underwent semi-structured neuropsychiatric examinations in 2000–2001. Follow-up examinations were carried out in 2005–2006 and 2009–2010. The timing of dementia onset was analysed using Cox proportional hazards regression. Results: The presence of the APOE ε4 allele affected the risk of developing dementia in both genders. Among women, distant social networks had a protective effect on dementia, while among men the significant associations between close social networks and dementia did not remain after controlling for covariates. Significant interactions between social networks and the APOE ε4 allele were not found. Conclusion: Strong social networks do not seem to moderate the increased risk of dementia implied by the APOE ε4 allele. Nevertheless, our results underline the importance of strong social networks in postponing dementia onset and indicate that their impact may differ among men and women.
Fetal and maternal responses to yoga in the third trimester

Abstract Objective: The primary purpose of this study was to examine maternal and fetal responses to a typical, moderate-intensity yoga session in healthy pregnant women during the third trimester using continuous monitoring. Methods: This prospective observational study in low-risk, pregnant women used the Monica AN24 Abdominal ECG wireless maternal-fetal monitor to measure fetal heart rate, maternal heart rate, and uterine activity during a prenatal yoga session. Sessions included 4 time periods: (1) 20-minute rest, (2) 50 minutes standard prenatal yoga, (3) 10-minute meditation, (4) 20-minute recovery. Data were continuously recorded throughout the entire session, stored at 0.25-second intervals, and then averaged over 5-minute intervals. To evaluate changes over time, overall means for the four time periods (rest, yoga, meditation, recovery) were compared using one-way ANOVA with repeated measures. Post-hoc pairwise comparisons (Tukey’s) were used to probe significant differences between the four time points. Statistical significance was reached at p < . 05. Results: Twenty participants were enrolled; 19 completed the yoga session. Mean gestational age was 35 weeks and 6 days (range of 32–0/7 to 38–6/7) with an average participant age of 32 ± 2.7 years. Maternal heart rates significantly increased during the yoga period (102 ± 11 bpm) compared to rest (90 ± 10), meditation (85 ± 12), and recovery (88 ± 10) (p < .01). The maximum maternal heart rate reached during the yoga session was 125 ± 13 bpm. While fetal heart rates fluctuated slightly over the course of the yoga session, there were no significant fetal heart rate decelerations to suggest deleterious fetal effects. There were no statistically significant differences among resting (138 ± 14 bpm), yoga (137 ± 11 bpm), meditation (139 ± 7 bpm), or recovery (135 ± 22 bpm) fetal heart rates (p = .814). Uterine activity was significantly greater during the yoga period compared with the other time points (p < .001). Conclusion: Yoga can be recommended for low-risk women during pregnancy as no adverse fetal or maternal heart rate changes were observed during a typical prenatal yoga session.
Biocide Exposure Induces Changes in Susceptibility, Pathogenicity, and Biofilm Formation in Uropathogenic Escherichia coli

Uropathogenic Escherichia coli (UPEC) is a frequent cause of catheter-associated urinary tract infection (CAUTI). Biocides have been incorporated into catheter coatings to inhibit bacterial colonization while, ideally, exhibiting low cytotoxicity and mitigating the selection of resistant bacterial populations. ABSTRACT Uropathogenic Escherichia coli (UPEC) is a frequent cause of catheter-associated urinary tract infection (CAUTI). Biocides have been incorporated into catheter coatings to inhibit bacterial colonization while, ideally, exhibiting low cytotoxicity and mitigating the selection of resistant bacterial populations. We compared the effects of long-term biocide exposure on susceptibility, biofilm formation, and relative pathogenicity in eight UPEC isolates. MICs, minimum bactericidal concentrations (MBCs), minimum biofilm eradication concentrations (MBECs), and antibiotic susceptibilities were determined before and after long-term exposure to triclosan, polyhexamethylene biguanide (PHMB), benzalkonium chloride (BAC), and silver nitrate. Biofilm formation was quantified using a crystal violet assay, and relative pathogenicity was assessed via a Galleria mellonella waxworm model. Cytotoxicity and the resulting biocompatibility index values were determined by use of an L929 murine fibroblast cell line. Biocide exposure resulted in multiple decreases in biocide susceptibility in planktonic and biofilm-associated UPEC. Triclosan exposure induced the largest frequency and magnitude of susceptibility decreases at the MIC, MBC, and MBEC, which correlated with an increase in biofilm biomass in all isolates. Induction of antibiotic cross-resistance occurred in 6/84 possible combinations of bacteria, biocide, and antibiotic. Relative pathogenicity significantly decreased after triclosan exposure (5/8 isolates), increased after silver nitrate exposure (2/8 isolates), and varied between isolates for PHMB and BAC. The biocompatibility index ranked the antiseptic potential as PHMB > triclosan > BAC > silver nitrate. Biocide exposure in UPEC may lead to reductions in biocide and antibiotic susceptibility, changes in biofilm formation, and alterations in relative pathogenicity. These data indicate the multiple consequences of biocide adaptation that should be considered when selecting an anti-infective catheter-coating agent.
Non-invasive assessment of tumor PD-L1 status with circulating tumor cells.

Now FDA-approved in the treatment of over ten malignancies, checkpoint blockade agents have transformed the treatment of cancer. These agents work by inhibiting the PD-1/PD-L1 interaction between cytotoxic T cells and tumor cells, an interaction which promotes immune evasion. PD-L1 expression levels by tumor cells, as assessed by tissue biopsy, is currently the most well-validated and clinically used predictive biomarker of response to checkpoint blockade agents (1,2). However, PD-L1 level is known to be an imperfect biomarker, and some FDA approvals do not set a PD-L1 expression level threshold to determine patient candidacy for checkpoint blockade.
Nigerian patients' perception of infection control measures in dentistry

Introduction: The growing prevalence of infectious diseases amon g patients in dentistry necessitates the need for appropriate compliance with recommended procedures for infection prevention and control cross-infectio n practices to prevent unnecessary spread of infections in the dental sett ings/clinics. Objective: To assess Nigerian patients' perceptions on the us e of gloves, facemasks and goggles by dentists in dental practice, as well as their knowledge on methods of sterilization and their awareness of cross-infection in dentistry. Methods: A descriptive cross sectional survey of patients a ttending the Periodontal Clinic of University of Benin teaching hospitals, N igeria was conducted in 2009. Results: Of 405 patients who responded, 98.3% believed that dentists should always wear gloves wh en treating patients. Twenty (4.9%) of respondents believed that gloves protects dentists only and 79.5% would be reluctant to receive treatment if the dentist didn't wear gl oves. About one-fifth (21.2%) of the respondents believed that facemasks protects dentists only and 59.3% would be reluctant to rece ive treatment if the dentist didn't wear a facemask. One-third (31.1 %) of the respondents believed that dentists should always wear goggles when treating patients. The majority (96.8%) were concer ned about sterilization of dental instruments used for their treatment but only 41.2% had ever asked the dentist how the instrument s were sterilized. Awareness of cross infection in dental clinic was reported by 84.7%. Conclusion: This study revealed poor patient's knowledge about infection control measures in dentistry. This data will serve in planning effective interventions to e nhance public awareness about infection control in dentistry in Benin City, Nigeria.
High KRT8 Expression Independently Predicts Poor Prognosis for Lung Adenocarcinoma Patients

Keratin 8 (KRT8), a type II basic intermediate filament (IF) protein, is essential for the development and metastasis of various cancers. In this study, by analyzing RNA-seq data from the Cancer Genome Atlas (TCGA)-lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC), we have determined the expression profile of KRT8, and assessed its prognostic significance and the possible mechanism underlying the dysregulation. Our results showed that KRT8 mRNA expression was significantly up-regulated in both LUAD and LUSC tissues compared with normal lung tissues. The high KRT8 expression group for LUAD patients significantly reduced overall survival (OS) and recurrence-free survival (RFS). Univariate and multivariate analysis revealed that KRT8 expression was an independent prognostic indicator for poor OS and RFS in LUAD patients. However, KRT8 expression had no prognostic value in terms of OS and RFS for LUSC. By exploring DNA copy number alterations (CNAs) of the KRT8 gene in LUAD, we found that DNA low copy gain (+1 and +2) was associated with elevated KRT8 mRNA expression. From the above findings, we have deduced that KRT8 is aberrantly expressed in LUAD tissues and that its expression might independently predict poor OS and RFS for LUAD patients, but not for LUSC patients.
Central Effects of Botulinum Neurotoxin—Evidence from Human Studies

For more than three decades, Botulinum neurotoxin (BoNT) has been used to treat a variety of clinical conditions such as spastic or dystonic disorders by inducing a temporary paralysis of the injected muscle as the desired clinical effect. BoNT is known to primarily act at the neuromuscular junction resulting in a biochemical denervation of the treated muscle. However, recent evidence suggests that BoNT’s pharmacological properties may not only be limited to local muscular denervation at the injection site but may also include additional central effects. In this review, we report and discuss the current evidence for BoNT’s central effects based on clinical observations, neurophysiological investigations and neuroimaging studies in humans. Collectively, these data strongly point to indirect mechanisms via changes to sensory afferents that may be primarily responsible for the marked plastic effects of BoNT on the central nervous system. Importantly, BoNT-related central effects and consecutive modulation and/or reorganization of the brain may not solely be considered “side-effects” but rather an additional therapeutic impact responsible for a number of clinical observations that cannot be explained by merely peripheral actions.
A qualitative study on physical health threatening factors of Iranian seafarers working on ocean going tankers.

BACKGROUND Seafaring is a highly physically demanding profession in a risky environment due to exposure to unique job health related risk factors. The purpose of the study is to describe physical health threatening factors of Iranian seafarers working on tankers. MATERIALS AND METHODS A qualitative content analysis with inductive approach was performed on 17 Iranian male seafarers in 2016. Subjects were selected by purposive sampling, which continued until data saturation. Data were gathered using semi-structural questionnaire via in-depth-interviews. All interviews were transformed into computer files. Analysis was done based on conventional content analysis approach. RESULTS Mean job history and age of the participants was 11.9 ± 7.2 and 35.8 ± 9.3 years, respectively. Two main themes emerged during analysis of data and categories were created. The themes are (1) physical health threatening factors at the ship; (2) high risk ranks at the ship. CONCLUSIONS The need for addressing nutrition at sea was acknowledged by seafarers. Also, it seems that revision of some regulations regarding seafarers' medical examination, oral health and heart diseases is necessary.
Iron Homeostasis in the Lungs—A Balance between Health and Disease

A strong mechanistic link between the regulation of iron homeostasis and oxygen sensing is evident in the lung, where both systems must be properly controlled to maintain lung function. Imbalances in pulmonary iron homeostasis are frequently associated with respiratory diseases, such as chronic obstructive pulmonary disease and with lung cancer. However, the underlying mechanisms causing alterations in iron levels and the involvement of iron in the development of lung disorders are incompletely understood. Here, we review current knowledge about the regulation of pulmonary iron homeostasis, its functional importance, and the link between dysregulated iron levels and lung diseases. Gaining greater knowledge on how iron contributes to the pathogenesis of these diseases holds promise for future iron-related therapeutic strategies.
Subcutaneous Implantable Cardioverter‐Defibrillator in Patients With Arrhythmogenic Right Ventricular Cardiomyopathy/Dysplasia: A Transatlantic Experience

Background Despite growing use of the subcutaneous implantable cardioverter‐defibrillator (S‐ICD), its clinical role in arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) patients remains undefined. We aim to elucidate the cardiac phenotype, implant characteristics, and long‐term efficacy regarding appropriate therapy and complications in ARVC/D patients with an S‐ICD implant. Methods and Results A transatlantic cohort of ARVC/D patients who underwent S‐ICD implantation was analyzed for clinical characteristics, S‐ICD therapy, and long‐term outcome including device‐related complications. The cohort included 29 patients (52% male, 76% probands, 59% with ARVC/D‐associated mutation, 59% primary prevention [no prior sustained ventricular arrhythmias], and 45% first‐generation S‐ICD devices). At implant, all inducible patients (27/29) had conversion of induced ventricular fibrillation. Two patients (7%) had superficial infections of the incision site that were treated conservatively. Over a median follow‐up of 3.16 years (interquartile range: 2.21–4.51 years), all episodes (6 patients, 4% per year) of sustained ventricular arrhythmias were appropriately detected and treated. Six patients (21%) experienced 39 inappropriate shocks, with 3 requiring device explantation. Oversensing of noncardiac signal (n=4; especially myopotentials) and cardiac signal (n=4) was the most frequent etiology. No lead or device dislodgement, infection, skin erosion, or explantation related to need for antitachycardia pacing was noted. Conclusions S‐ICD can effectively treat both induced and spontaneous ventricular arrhythmias in patients with ARVC/D. The rate of inappropriate shocks, although considerable, is comparable to that in ARVC/D patients treated with transvenous ICDs. When they occurred, inappropriate shocks were primarily due to cardiac and, uniquely, noncardiac oversensing. We suggest potential strategies for minimizing inappropriate therapy.
Communicating information and professional knowledge in acquired brain injury rehabilitation trajectories – a qualitative study of physiotherapy practice

Abstract Purpose: The communication of information and professional knowledge is paramount during patient transitions, and conveying practice knowledge is an important part of the health professional’s role. Physiotherapy interventions in both specialist and primary health care are often necessary to aid persons in rehabilitation following an acquired brain injury (ABI). The aim of this study was to investigate how physiotherapists experience the way patient information is communicated across health care levels in ABI rehabilitation. Methods: We performed interviews with a total of 19 physiotherapists related to the rehabilitation trajectories of 10 people with acquired brain injuries. We performed a systematic text condensation analysis informed by constructionist and interactionist perspectives and theories of learning. Results: The physiotherapists in this study considered the patients to be complex and resource intensive. Written information upon hospital discharge was necessary but not sufficient, and they emphasized the need for verbal communication and closer collaboration across health care levels and clinical settings. Conclusions: The findings in this study indicate the need to improve routines for the communication of information and to clarify issues related to economy and responsibilities. Collaboration across health care levels require reciprocal understanding of the contextual differences in rehabilitation trajectories. Implications for rehabilitation The discharge process is an important arena for continuous development of collaborative practices in the neurological rehabilitation context. Rehabilitation trajectories should be customized for the specific patient in a manner that is closely connected to contextual limitations and affordances. Communication between health care professionals in the transitional phase of rehabilitation trajectories is important to identify altered prerequisites for providing rehabilitation services in the primary care context.
Continuous integrated antibody precipitation with two‐stage tangential flow microfiltration enables constant mass flow

Continuous precipitation is a new unit operation for the continuous capture of antibodies. The capture step is based on continuous precipitation with PEG6000 and Zn++ in a tubular reactor integrated with a two‐stage continuous tangential flow filtration unit. The precipitate cannot be separated with centrifugation, because a highly compressed sediment results in poor resolubilization. We developed a new two‐stage tangential flow microfiltration method, where part of the concentrated retentate of the first stage was directly fed to the second stage, together with the wash buffer. Thus, the precipitate was concentrated and washed in a continuous process. We obtained 97% antibody purity, a 95% process yield during continuous operation, and a fivefold reduction in pre‐existing high‐molecular‐weight impurities. For other unit operations, surge tanks are often required, due to interruptions in the product mass flow out of the unit operation (e.g., the bind/elute mode in periodic counter‐current chromatography). Our setup required no surge tanks; thus, it provided a truly continuous antibody capture operation with uninterrupted product mass flow. Continuous virus inactivation and other flow‐through unit operations can be readily integrated downstream of the capture step to create truly continuous, integrated, downstream antibody processing without the need for hold tanks.
