Light Fluence Rate and Tissue Oxygenation (StO2) Distributions Within the Thoracic Cavity of Patients Receiving Intraoperative Photodynamic Therapy for Malignant Pleural Mesothelioma

The distributions of light and tissue oxygenation (StO2) within the chest cavity were determined for 15 subjects undergoing macroscopic complete resection followed by intraoperative photodynamic therapy (PDT) as part of a clinical trial for the treatment of malignant pleural mesothelioma (MPM). Over the course of light delivery, detectors at each of eight different sites recorded exposure to variable fluence rate. Nevertheless, the treatment‐averaged fluence rate was similar among sites, ranging from a median of 40–61 mW cm−2 during periods of light exposure to a detector. StO2 at each tissue site varied by subject, but posterior mediastinum and posterior sulcus were the most consistently well oxygenated (median StO2 >90%; interquartile ranges ~85–95%). PDT effect on StO2 was characterized as the StO2 ratio (post‐PDT StO2/pre‐PDT StO2). High StO2 pre‐PDT was significantly associated with oxygen depletion (StO2 ratio < 1), although the extent of oxygen depletion was mild (median StO2 ratio of 0.8). Overall, PDT of the thoracic cavity resulted in moderate treatment‐averaged fluence rate that was consistent among treated tissue sites, despite instantaneous exposure to high fluence rate. Mild oxygen depletion after PDT was experienced at tissue sites with high pre‐PDT StO2, which may suggest the presence of a treatment effect.
Melatonin Application Improves Salt Tolerance of Alfalfa (Medicago sativa L.) by Enhancing Antioxidant Capacity

Alfalfa (Medicago sativa L.) is an important and widely cultivated forage grass. The productivity and forage quality of alfalfa are severely affected by salt stress. Melatonin is a bioactive molecule with versatile physiological functions and plays important roles in response to various biotic and abiotic stresses. Melatonin has been proven efficient in improving alfalfa drought and waterlogging tolerance in recent studies. In our reports, we applied melatonin exogenously to explore the effects of melatonin on alfalfa growth and salt resistance. The results demonstrated that melatonin application promoted alfalfa seed germination and seedling growth, and reduced oxidative damage under salt stress. Further application research found that melatonin alleviated salt injury in alfalfa plants under salt stress. The electrolyte leakage, malondialdehyde (MDA) content and H2O2 content were significantly reduced, and the activities of catalase (CAT), peroxidase (POD), and Cu/Zn superoxide dismutase (Cu/Zn-SOD) were increased with melatonin pretreatment compared to control plants under salt stress with the upregulation of genes related to melatonin and antioxidant enzymes biosynthesis. Melatonin was also involved in reducing Na+ accumulation in alfalfa plants. Our study indicates that melatonin plays a primary role as an antioxidant in scavenging H2O2 and enhancing activities of antioxidant enzymes to improve the salt tolerance of alfalfa plants.
Lipid accumulation product and late-onset hypogonadism in middle-aged and elderly men: results from a cross-sectional study in China

Objectives Hypogonadism in men is related to the deterioration of general health. However, the association between lipid overaccumulation and ageing-related hypogonadism remains an undetermined concept. We aimed to provide an insight into the possible links between the lipid accumulation product (LAP) and late-onset hypogonadism (LOH). Setting Sun Yat-sen Memorial Hospital of Sun Yat-sen University. Participants We included a population sample of 997 subjects aged 40 years or older. Primary and secondary outcome measures The LAP was calculated by gender-specific equations using waist circumference (WC) and triglyceride (TG). LOH was defined by the presence of androgen deficiency symptoms and low serum total testosterone levels. Results The prevalence of LOH was 9.4% in this population and gradually increased according to increasing LAP quartiles. Compared with subjects without LOH, ageing men with LOH had higher body mass index, WC, systolic blood pressure, percentage of subjects currently smoking, TG and follicle stimulating hormone and lower low-density lipoprotein cholesterol and sex hormone binding globulin. In multivariate logistic regression analysis, the adjusted ORs of LOH for increasing LAP quartiles 1–4 were 1.00 (reference), 1.10 (95% CI 0.45–2.69), 2.15 (95% CI 0.93–4.94) and 3.83 (95% CI 1.73–8.45), respectively. Conclusion Body lipid accumulation evaluated by the LAP is independently associated with the prevalence of LOH in middle-aged and elderly Chinese men.
The Influence of Type 1 Diabetes Mellitus on Amplitude of Accommodation

ABSTRACT Purpose The aim of the study was to assess the amplitude of accommodation (AA) in patients with type 1 diabetes mellitus (DM) and without diabetic retinopathy. Materials and Methods In two age- and sex-matched groups – one with twenty-nine eyes of 29 patients with type 1 DM, the other with twenty-nine eyes of 29 healthy individuals – retinal nerve fibre layer thickness and macular volume were determined by using optic coherence tomography in all quadrants, whereas AA was measured with the minus lens technique. The mean values of all three measurements were compared between the groups, and the effect of age, disease duration, (HbA1c and fasting blood glucose on AA were analysed using multiple regression analysis. Results On average, participants were 25.0 ± 3.3 years old (range 19–30) in both groups (P = 1.000), and patients had type 1 DM for an average of 13.0 ± 3.3 years. Mean AA in the right eye was 7.3 ± 1.1 D among patients and 8.1 ± 1.1 D among controls (P = .005), as well as significantly negatively correlated with age in both groups (r = −0.735, P <.001 and r = −0.819, P < .001, respectively) and disease duration among patients (r = −0.434, P = .019). In multivariable regression, age and disease duration significantly affected AA in patients, with an R 2 value of 0.623 (P < .001 and P = .025, respectively). Average RNFL thickness was significantly different between the groups (P = .014). Mean macular volumes for areas 1, 3 or 5 mm in diameter were similar between the groups. Conclusions AA was significantly lower among patients with type 1 DM than among healthy individuals, which suggests that the former might experience presbyopia earlier in life than the general population.
Do People Want to Be More Moral?

Most people want to change some aspects of their personality, but does this phenomenon extend to moral character and to close others? Targets (n = 800) rated their personality traits and reported how much they wanted to change on each trait; well-acquainted informants (n = 958) rated targets’ personality traits and how much they wanted the targets to change on those same traits. Targets and informants reported a lower desire to change more morally relevant traits (e.g., honesty, compassion, fairness) compared with less morally relevant traits (e.g., anxiety, sociability, productiveness)—even after we controlled for current trait levels. Moreover, although targets generally wanted to improve more on traits that they had less desirable levels of, and informants wanted their targets to improve more on those traits as well, targets’ moral change goals were less calibrated to their current trait levels. Finally, informants wanted targets to change in similar ways, but to a lesser extent, than targets themselves did. These findings suggest that moral considerations take a back seat when it comes to self-improvement.
Human-In-The-Loop Assessment of an Ultralight, Low-Cost Body Posture Tracking Device

In rehabilitation, assistive and space robotics, the capability to track the body posture of a user in real time is highly desirable. In more specific cases, such as teleoperated extra-vehicular activity, prosthetics and home service robotics, the ideal posture-tracking device must also be wearable, light and low-power, while still enforcing the best possible accuracy. Additionally, the device must be targeted at effective human-machine interaction. In this paper, we present and test such a device based upon commercial inertial measurement units: it weighs 575 g in total, lasts up to 10.5 h of continual operation, can be donned and doffed in under a minute and costs less than 290 EUR. We assess the attainable performance in terms of error in an online trajectory-tracking task in Virtual Reality using the device through an experiment involving 10 subjects, showing that an average user can attain a precision of 0.66 cm during a static precision task and 6.33 cm while tracking a moving trajectory, when tested in the full peri-personal space of a user.
Validation of an Electronic Visual Analog Scale mHealth Tool for Acute Pain Assessment: Prospective Cross-Sectional Study

Background Accurate measurement of pain is required to improve its management and in research. The visual analog scale (VAS) on paper format has been shown to be an accurate, valid, reliable, and reproducible way to measure pain intensity. However, some limitations should be considered, some of which can be implemented with the introduction of an electronic VAS version, suitable to be used both in a tablet and a smartphone. Objective This study aimed to validate a new method of recording pain level by comparing the traditional paper VAS with the pain level module on the newly designed Interactive Clinics app. Methods A prospective observational cross-sectional study was designed. The sample consisted of 102 participants aged 18 to 65 years. A Force Dial FDK 20 algometer (Wagner Instruments) was employed to induce mild pressure symptoms on the participants’ thumbs. Pain was measured using a paper VAS (10 cm line) and the app. Results Intermethod reliability estimated by ICC(3,1) was 0.86 with a 95% confidence interval of 0.81 to 0.90, indicating good reliability. Intramethod reliability estimated by ICCa(3,1) was 0.86 with a 95% confidence interval of 0.81 to 0.90, also indicating good reliability. Bland-Altman analysis showed a difference of 0.175 (0.49), and limits of agreement ranged from –0.79 to 1.14. Conclusions The pain level module on the app is highly reliable and interchangeable with the paper VAS version. This tool could potentially help clinicians and researchers precisely assess pain in a simple, economic way with the use of a ubiquitous technology.
Patellofemoral Joint Stress during Running with Added Load in Females

Abstract Patellofemoral joint (PFJ) pain syndrome is a commonly reported form of pain in female runners and military personnel. Increased PFJ stress may be a contributing factor. Few studies have examined PFJ stress running with added load. Our purpose was to analyze PFJ stress, PFJ reaction force, quadriceps force, knee flexion angle, and other kinematic and temporospatial variables running with and without a 9 kg load. Nineteen females ran across a force platform with no added load and 9.0 kg weight vest. Kinematic data were collected using 3D motion capture and kinetic data with a force platform. Muscle forces were estimated using a musculoskeletal model, and peak PFJ loading variables were calculated during stance. Multivariate analyses were run on PFJ loading variables and on cadence, step length and foot strike index. Differences were shown in PFJ stress, PFJ reaction force, peak knee flexion angle and quadriceps force. Joint specific kinetic variables increased between 5–16% with added load. PFJ loading variables increased with 9 kg of added load without changes in cadence, step length, or foot strike index compared to no load. Added load appears to increase the PFJ loading variables associated with PFJ pain in running.
Introducing artificial intelligence in acute psychiatric inpatient care: qualitative study of its use to conduct nursing observations

Background All patients admitted to an acute inpatient mental health unit must have nursing observations carried out at night either hourly or every 15 minutes, to ascertain that they are safe and breathing. However, while this practice ensures patient safety, it can also disturb patients’ sleep, which in turn can impact negatively on their recovery. Objective This article describes the process of introducing artificial intelligence (‘digitally assisted nursing observations’) in an acute mental health inpatient ward, to enable staff to carry out the hourly and the 15 minutes observations, minimising disruption of patients’ sleep while maintaining their safety. Findings The preliminary data obtained indicate that the digitally assisted nursing observations agreed with the observations without sensors when both were carried out in parallel and that over an estimated 755 patient nights, the new system has not been associated with any untoward incidents. Preliminary qualitative data suggest that the new technology improves patients’ and staff’s experience at night. Discussion This project suggests that the digitally assisted nursing observations could maintain patients’ safety while potentially improving patients’ and staff’s experience in an acute psychiatric ward. The limitations of this study, namely, its narrative character and the fact that patients were not randomised to the new technology, suggest taking the reported findings as qualitative and preliminary. Clinical implications These results suggest that the care provided at night in acute inpatient psychiatric units could be substantially improved with this technology. This warrants a more thorough and stringent evaluation.
A physiological model for predicting dynamics of tree stem‐wood non‐structural carbohydrates

Non‐structural carbohydrates (NSC) are considered important in the metabolism of wood plants, and they are highly dynamic. Accurate and detailed modelling of NSC dynamics may increase the understanding of physiological processes. We constructed a physiological model that simulates NSC dynamics from photosynthesis, transpiration and growth carbon demand. With this model, we tested the hypotheses that production, allocation and storage explain tree‐ and forest‐level carbohydrates balance, and especially that cambial activities explain the major portion of carbon consumption. We applied this model at one plot in Harvard Forest, Massachusetts, USA. The predicted results of stem‐wood NSC dynamics of 20 deciduous broad‐leaved trees corresponded well with measurements. NSC (i.e. product from photosynthesis) allocations depended on thermal time and the development stage of each organ. Water movements driven by water potential gradients in whole‐trees also influenced tree growth, which was a necessary process for predicting the daily NSC dynamics. Synthesis. This model combined wood growth at whole‐tree scale and carbohydrates balance at cellular scale with short‐term vegetation hydraulics. The model provides a foundation to further understand the complex interactions between environmental factors and tree carbon allocation.
The prevalence of amphenicol resistance in Escherichia coli isolated from pigs in mainland China from 2000 to 2018: A systematic review and meta-analysis

Background Amphenicols have been widely used in the pig industry in China, leading to varying degrees of drug resistance. Methods The systematic review was performed according to PRISMA (Preferred Reported Items for Systematic Reviews and Meta-Analysis) recommendations on studies investigating the prevalence of amphenicol-resistant Escherichia coli (E. coli) isolated from pig in mainland China from 2000 to 2018, a random-effects model was selected, then followed by meta-analysis. Results A total of 103 articles were included in the study. The results of the meta-analysis revealed that the pooled summarized prevalence of resistance to chloramphenicol (CAP) was 72.31% (95% confidence interval (95% CI) = 67.12%–77.23%) and to florfenicol (FF) was 58.64% (95% CI = 52.48%–64.67%). During the past 18 years, the resistance rate to CAP remained high initially but then declined rapidly after 2012, whereas the resistance rate to FF plateaued (54.13%–59.60%) from 2000–2018. In different parts of China, the rate of resistance to amphenicols among E. coli isolates was fairly consistent, with the exception of the north and northwest regions. Conclusions In 2002, the veterinary use of CAP was prohibited and its resistance levels in E. coli isolated from pigs was initially maintained at a high level but then showed an obvious downward trend in recent years. Resistance to commonly used FF remained at a high but stable level.
Whole Genome Sequencing Results Associated with Minimum Inhibitory Concentrations of 14 Anti-Tuberculosis Drugs among Rifampicin-Resistant Isolates of Mycobacterium Tuberculosis from Iran

Accurate and timely detection of drug resistance can minimize the risk of further resistance development and lead to effective treatment. The aim of this study was to determine the resistance to first/second-line anti-tuberculosis drugs in rifampicin/multidrug-resistant Mycobacterium tuberculosis (RR/MDR-MTB) isolates. Molecular epidemiology of strains was determined using whole genome sequencing (WGS)-based genotyping. A total of 35 RR/MDR-MTB isolates were subjected to drug susceptibility testing against first/second-line drugs using 7H9 Middlebrook in broth microdilution method. Illumina technology was used for paired-end WGS applying a Maxwell 16 Cell DNA Purification kit and the NextSeq platform. Data analysis and single nucleotide polymorphism calling were performed using MTBseq pipeline. The genome-based resistance to each drug among the resistant phenotypes was as follows: rifampicin (97.1%), isoniazid (96.6%), ethambutol (100%), levofloxacin (83.3%), moxifloxacin (83.3%), amikacin (100%), kanamycin (100%), capreomycin (100%), prothionamide (100%), D-cycloserine (11.1%), clofazimine (20%), bedaquiline (0.0%), and delamanid (44.4%). There was no linezolid-resistant phenotype, and a bedaquiline-resistant strain was wild type for related genes. The Beijing, Euro-American, and Delhi-CAS were the most populated lineage/sublineages. Drug resistance-associated mutations were mostly linked to minimum inhibitory concentration results. However, the role of well-known drug-resistant genes for D-cycloserine, clofazimine, bedaquiline, and delamanid was found to be more controversial.
Multi-Channel Neural Recording Implants: A Review

The recently growing progress in neuroscience research and relevant achievements, as well as advancements in the fabrication process, have increased the demand for neural interfacing systems. Brain–machine interfaces (BMIs) have been revealed to be a promising method for the diagnosis and treatment of neurological disorders and the restoration of sensory and motor function. Neural recording implants, as a part of BMI, are capable of capturing brain signals, and amplifying, digitizing, and transferring them outside of the body with a transmitter. The main challenges of designing such implants are minimizing power consumption and the silicon area. In this paper, multi-channel neural recording implants are surveyed. After presenting various neural-signal features, we investigate main available neural recording circuit and system architectures. The fundamental blocks of available architectures, such as neural amplifiers, analog to digital converters (ADCs) and compression blocks, are explored. We cover the various topologies of neural amplifiers, provide a comparison, and probe their design challenges. To achieve a relatively high SNR at the output of the neural amplifier, noise reduction techniques are discussed. Also, to transfer neural signals outside of the body, they are digitized using data converters, then in most cases, the data compression is applied to mitigate power consumption. We present the various dedicated ADC structures, as well as an overview of main data compression methods.
Characterization of posterior leakage in swallowing.

PURPOSE To describe and characterize a finding, i.e., delayed posterior leakage of food residue during swallowing, according to age, gender and food consistency, which occurred in the event. METHODS Data were collected through the analysis of each functional videonasoendoscopy test of swallowing previously recorded in a specialist outpatient clinic. The study population included 200 patients, both males and females, aged between 46 and 87 years, with and without an underlying pathology for dysphagia. The images were studied individually by the researcher and analyzed by judges in order to identify and select images that would confirm the presence or absence of the study event. RESULTS Delayed escape was found in 45 out of the 200 analyzed tests. The tests selected for the study showed delayed posterior bolus leakage in at least one consistency. The highest frequency of delayed posterior leakage occurred with fluids. The analysis showed the significance of the study event with the population related to older ages in the sample analyzed. CONCLUSION Delayed posterior leakage occurs predominantly in the liquid consistency in older populations with no gender predominance.
DNA Damage in Blood Leukocytes of Prostate Cancer Patients Undergoing PET/CT Examinations with [68Ga]Ga-PSMA I&T

The aim was to investigate the induction and repair of radiation-induced DNA double-strand breaks (DSBs) as a function of the absorbed dose to the blood of patients undergoing PET/CT examinations with [68Ga]Ga-PSMA. Blood samples were collected from 15 patients before and at four time points after [68Ga]Ga-PSMA administration, both before and after the PET/CT scan. Absorbed doses to the blood were calculated. In addition, blood samples with/without contrast agent from five volunteers were irradiated ex vivo by CT while measuring the absorbed dose. Leukocytes were isolated, fixed, and stained for co-localizing γ-H2AX+53BP1 DSB foci that were enumerated manually. In vivo, a significant increase in γ-H2AX+53BP1 foci compared to baseline was observed at all time points after administration, although the absorbed dose to the blood by 68Ga was below 4 mGy. Ex vivo, the increase in radiation-induced foci depended on the absorbed dose and the presence of contrast agent, which could have caused a dose enhancement. The CT-dose contribution for the patients was estimated at about 12 mGy using the ex vivo calibration. The additional number of DSB foci induced by CT, however, was comparable to the one induced by 68Ga. The significantly increased foci numbers after [68Ga]Ga-PSMA administration may suggest a possible low-dose hypersensitivity.
