Acute Febrile Illness Caused by Brucella Abortus Infection in Humans in Pakistan

Brucellosis is a zoonosis of great and worldwide public health concern that can cause a severe febrile illness in humans. In Pakistan, brucellosis is a critical problem in both animals and humans. This study aimed to gain insight into its prevalence and to analyze the potential risk factors of patients with acute febrile illness (AFI) of an unknown cause, at the hospitals of Rawalpindi and Islamabad in Pakistan. In total, 446 blood samples were collected from patients and screened for brucellosis using the Rose Bengal Plat Test (RBPT). All the serum samples were investigated for Brucella DNA using specific real-time PCR. Age, sex, occupation, urbanicity, socioeconomic status and history of animal contact were recorded and assessed as potential risk factors. The proportion of acute febrile illness patients for whom brucellosis could be suspected was 10.1% by the RBPT. Brucella DNA was detected in 26 (5.8%) cases and identified as B. abortus. Contact with infected animals, consumption of raw milk and socioeconomic status showed a highly significant (p < 0.05) correlation with seropositivity. Elderly patients (19.7% RBPT and 12.1% PCR) and females (13% RBPT and 9.3% PCR) were of high risk of brucellosis. Patients suffering from brucellosis-related manifestations should be screened for brucellosis, especially those in contact with animals or those consuming their unprocessed products, given the increased risk. The results of this study, which highlight that Brucella abortus as an important cause of acute febrile illnesses in humans, aid the development of effective control strategies for human brucellosis in Pakistan.
Cost-effectiveness of psychological interventions for children and young people with post-traumatic stress disorder.

BACKGROUND PTSD in youth may lead to long-lasting psychological implications, educational difficulties and increased healthcare costs. Psychological interventions have been shown to be effective in its management. The objective of this study was to assess the cost-effectiveness of a range of psychological interventions for children and young people with PTSD. METHODS A decision-analytic model was constructed to compare costs and quality-adjusted life years (QALYs) of 10 psychological interventions and no treatment for children and young people with PTSD, from the perspective of the National Health Service and personal social services in England. Effectiveness data were derived from a systematic review and network meta-analysis. Other model input parameters were based on published sources, supplemented by expert opinion. RESULTS Cognitive therapy for PTSD, a form of individual trauma-focused cognitive behavioural therapy (TF-CBT), appeared to be the most cost-effective intervention for children and young people with PTSD (with a probability of .78 amongst the 11 evaluated options at a cost-effectiveness threshold of £20,000/QALY), followed by narrative exposure (another form of individual TF-CBT), play therapy, and other forms of individual TF-CBT. After excluding cognitive therapy from the analysis, narrative exposure appeared to be the most cost-effective option with a . 40 probability of being cost-effective amongst the remaining 10 options. EMDR, parent training and group TF-CBT occupied middle cost-effectiveness rankings. Family therapy and supportive counselling were less cost-effective than other active interventions. There was limited evidence for some interventions, in particular cognitive therapy for PTSD and parent training. CONCLUSIONS Individual forms of TF-CBT and, to a lesser degree, play therapy appear to be cost-effective in the treatment of children and young people with PTSD. Family therapy and supportive counselling are unlikely to be cost-effective relative to other interventions. There is a need for well-conducted studies that examine the long-term clinical and cost-effectiveness of a range of psychological treatments for children and young people with PTSD.
The Manufacturing Process of Kiwifruit Fruit Powder with High Dietary Fiber and Its Laxative Effect

Kiwifruit is rich in vitamins, minerals, dietary fiber and other functional components, and it has long been used as a functional food to treat intestinal ailments such as constipation. The current research made full use of the kiwifruit, the juice was prepared by microencapsulation, and the dietary fiber in kiwifruit pomace was modified by enzymatic hydrolysis and grinding, then, the two were mixed to obtain an ultra-micro kiwifruit powder (UKP). In addition, the laxative effect of the UKP was verified by a diphenoxylate induced constipated mice model. The results demonstrated that compared with the raw samples, the retention rate of vitamin C, lutein and catechin in UKP were 83.3%, 81.9% and 88.3%, respectively, thus effectively avoiding the loss of functional components during the processing of kiwifruit. Moreover, α-amylase, protease and the ball milling process effectively reduced the size of dietary fiber in kiwifruit pomace, and its water-holding capacity (WHC), oil-holding capacity (OHC) and swelling capacity (SWC) were enhanced by 1.26, 1.65 and 1.10 times, respectively. Furthermore, to analyze the laxative effect of the UKP, a constipation mice model was established by diphenoxylate treatment (5 mg·kg−1, i.g.) for the last week, with or without UKP supplementation (2.4 g·kg−1 B.W. per day) for 4 weeks. The results demonstrated that UKP significantly increased feces condition (fecal output and dejecta moisture content, gut transit (the intestinal propulsion rates) and substance P (SP) levels in portal vein plasma, and it decreased the whole gut transit time and mucinogen granules secreted by goblet cell in constipated mice.
Association Between Low Blood Pressure and Clinical Outcomes in Patients With Acute Ischemic Stroke.

Background and Purpose- Low blood pressure is uncommon in patients with acute ischemic stroke (AIS). We assessed the association between baseline low blood pressure and outcomes in patients with AIS. Methods- Post hoc analysis of the PASS (Preventive Antibiotics in Stroke Study). We compared patients with AIS and low (<10th percentile) baseline systolic blood pressure (SBP) to patients with normal SBP (≥10th percentile <185 mm Hg). The first SBP measured at the Emergency Department was used. Outcomes included in-hospital mortality, major complications <7 days of stroke onset, and functional outcome at 90 days (modified Rankin scale score). We used regression analysis to calculate (common) odds ratios and adjusted for predefined prognostic factors. Results- Two thousand one hundred twenty-four out of 2538 patients had AIS. The cutoff for low SBP was 130 mm Hg (n=212; range, 70-129 mm Hg). One thousand four hundred forty patients had a normal SBP (range, 130-184 mm Hg). Low SBP was associated with an increased risk of in-hospital mortality (8.0% versus 4.2%; adjusted odds ratio [aOR], 1.58; 95% CI, 1.13-2.21) and complications (16.0% versus 6.5%; aOR, 2.56; 95% CI, 1.60-4.10). Specifically, heart failure (2.4% versus 0.1%; aOR, 17.85; 95% CI, 3.36-94.86), gastrointestinal bleeding (1.9% versus 0.1%; aOR, 26.04; 95% CI, 2.83-239.30), and sepsis (3.3% versus 0.5%; aOR, 5.53; 95% CI, 1.84-16.67) were more common in patients with low SBP. Functional outcome at 90 days did not differ (shift towards worse outcome: adjusted common odds ratio, 1.24; 95% CI, 0.95-1.61). Conclusions- Whether it is cause or consequence, low SBP at presentation in patients with AIS was associated with an increased risk of in-hospital mortality and complications, specifically heart failure, gastrointestinal bleeding, and sepsis. Clinicians should be vigilant for potentially treatable complications. Clinical Trial Registration- URL: https://www.controlled-trials.com. Unique identifier: ISRCTN66140176.
Safety and feasibility of an early telephone-supported home exercise program after anterior cervical discectomy and fusion: a case series

ABSTRACT Objective: To describe the safety, feasibility, and preliminary outcomes of an early telephone-supported home exercise program (HEP) performed within the first 6 weeks after anterior cervical discectomy and fusion (ACDF) surgery. Methods: Eight patients (mean ± SD age = 53.4 ± 14.9 years, 5 females) were enrolled in this case series. Immediately after surgery, patients began a 6-week HEP including daily walking, deep breathing, distraction techniques, and cervical and upper body exercises. The HEP was supported by weekly telephone calls by a physical therapist. Safety for performing early exercise was examined with radiographic imaging at 6 months. Adverse events were assessed through weekly calls with a physical therapist. HEP adherence and acceptability data were obtained by patient self-report. Clinical measures were assessed preoperatively, at 6 weeks and at 6 months, and included the Neck Disability Index, Numeric Rating Scale for pain, Tampa Scale of Kinesiophobia, Pain Catastrophizing Scale, Pain Self-Efficacy Questionnaire, and accelerometry for physical activity. Results: Early radiographic imaging showed no signs of nonunion at 6 months. There were no reports of serious adverse events. At 6 months, all patients reported clinically significant changes in pain catastrophizing. Seven (88%) patients had clinically significant changes in disability and arm pain, six (75%) patients for neck pain and pain self-efficacy, and five (53%) patients for fear of movement. Only three (43%) of seven patients showed increased physical activity at 6 months. Conclusion: Based on this small case series, an early telephone-supported HEP appears safe for patients, feasible to implement, and promising for clinical benefits.
Vector Quantization of High-Dimensional Speech Spectra Using Deep Neural Network

SUMMARY This paper proposes a deep neural network (DNN) based framework to address the problem of vector quantization (VQ) for high-dimensional data. The main challenge of applying DNN to VQ is how to reduce the binary coding error of the auto-encoder when the distribution of the coding units is far from binary. To address this problem, three ﬁne-tuning methods have been adopted: 1) adding Gaussian noise to the input of the coding layer, 2) forcing the output of the coding layer to be binary, 3) adding a non-binary penalty term to the loss function. These ﬁne-tuning methods have been extensively evaluated on quantizing speech magnitude spectra. The results demonstrated that each of the methods is useful for improving the coding performance. When implemented for quantizing 968-dimensional speech spectra using only 18-bit, the DNN-based VQ framework achieved an averaged PESQ of about 2.09, which is far beyond the capability of conventional VQ methods.
The Effectiveness of Tobacco Dependence Education in Health Professional Students’ Practice: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

The objective of this study was to perform a systematic review to examine the effectiveness of tobacco dependence education versus usual or no tobacco dependence education on entry-level health professional student practice and client smoking cessation. Sixteen published databases, seven grey literature databases/websites, publishers’ websites, books, and pertinent reference lists were searched. Studies from 16 health professional programs yielded 28 RCTs with data on 4343 healthcare students and 3122 patients. Two researchers independently assessed articles and abstracted data about student knowledge, self-efficacy, performance of tobacco cessation interventions, and patient smoking cessation. All forms of tobacco were included. We did not find separate interventions for different kinds of tobacco such as pipes or flavoured tobacco. We computed effect sizes using a random-effects model and applied meta-analytic procedures to 13 RCTs that provided data for meta-analysis. Students’ counseling skills increased significantly following the 5As model (SMD = 1.03; 95% CI 0.07, 1.98; p < 0.00001, I2 94%; p = 0.04) or motivational interviewing approach (SMD = 0.90, 95% CI 0.59, 1.21; p = 0.68, I2 0%; p < 0.00001). With tobacco dependence counseling, 78 more patients per 1000 (than control) reported quitting at 6 months (OR 2.02; 95% CI 1.49, 2.74, I2 = 0%, p = 0.76; p < 0.00001), although the strength of evidence was moderate or low. Student tobacco cessation counseling improved guided by the above models, active learning strategies, and practice with standardized patients.
Defining body-weight reduction as a humane endpoint: a critical appraisal

In many animal experiments scientists and local authorities define a body-weight reduction of 20% or more as severe suffering and thereby as a potential parameter for humane endpoint decisions. In this study, we evaluated distinct animal experiments in multiple research facilities, and assessed whether 20% body-weight reduction is a valid humane endpoint criterion in rodents. In most experiments (restraint stress, distinct models for epilepsy, pancreatic resection, liver resection, caloric restrictive feeding and a mouse model for Dravet syndrome) the animals lost less than 20% of their original body weight. In a glioma model, a fast deterioration in body weight of less than 20% was observed as a reliable predictor for clinical deterioration. In contrast, after induction of chronic diabetes or acute colitis some animals lost more than 20% of their body weight without exhibiting major signs of distress. In these two animal models an exclusive application of the 20% weight loss criterion for euthanasia might therefore result in an unnecessary loss of animals. However, we also confirmed that this criterion can be a valid parameter for defining the humane endpoint in other animal models, especially when it is combined with additional criteria for evaluating distress. In conclusion, our findings strongly suggest that experiment and model specific considerations are necessary for the rational integration of the parameter ‘weight loss’ in severity assessment schemes and humane endpoint criteria. A flexible implementation tailored to the experiment or intervention by scientists and authorities is therefore highly recommended.
T-cell-specific mTOR deletion in mice ameliorated CD4+ T-cell survival in lethal sepsis induced by severe invasive candidiasis

ABSTRACT The mammalian target of rapamycin (mTOR) pathway can mediate T-cell survival; however, the role of this pathway in T-cell survival during fungal sepsis is unclear. Here, we investigated the role of the mTOR pathway in CD4+ T-cell survival in a mouse model of rapidly progressive lethal sepsis induced by severe invasive candidiasis and explored the possible mechanism. The decrease in CD4+ T-cell survival following fungal sepsis was ameliorated in mice with a T-cell-specific mTOR deletion, whereas it was exacerbated in mice with a T-cell-specific tuberous sclerosis complex (TSC)1 deletion. To explore the mechanism further, we measured expression of autophagy proteins light chain 3B and p62/sequestosome 1 in CD4+ T cells. Both proteins were increased in T-cell-specific mTOR knockout mice but lower in T-cell-specific TSC1 knockout mice. Transmission electron microscopy revealed that T-cell-specific mTOR knockout mice had more autophagosomes than wild-type mice following fungal sepsis. CD4+ T-cell mTOR knockout decreased CD4+ T-cell apoptosis in fungal sepsis. Most notably, the T-cell-specific mTOR deletion mice had an increased survival rate after fungal sepsis. These results suggest that the mTOR pathway plays a vital role in CD4+ T-cell survival during fungal sepsis, partly through the autophagy–apoptosis pathway.
Heterogeneous antimicrobial activity in broncho-alveolar aspirates from mechanically ventilated intensive care unit patients

ABSTRACT Pneumonia is an infection of the lungs, where the alveoli in the affected area are filled with pus and fluid. Although ventilated patients are at risk, not all ventilated patients develop pneumonia. This suggests that the sputum environment may possess antimicrobial activities. Despite the generally acknowledged importance of antimicrobial activity in protecting the human lung against infections, this has not been systematically assessed to date. Therefore, the objective of the present study was to measure antimicrobial activity in broncho-alveolar aspirate (‘sputum”) samples from patients in an intensive care unit (ICU) and to correlate the detected antimicrobial activity with antibiotic levels, the sputum microbiome, and the respective patients’ characteristics. To this end, clinical metadata and sputum were collected from 53 mechanically ventilated ICU patients. The antimicrobial activity of sputum samples was tested against Streptococcus pneumoniae, Staphylococcus aureus and Streptococcus anginosus. Here we show that sputa collected from different patients presented a high degree of variation in antimicrobial activity, which can be partially attributed to antibiotic therapy. The sputum microbiome, although potentially capable of producing antimicrobial agents, seemed to contribute in a minor way, if any, to the antimicrobial activity of sputum. Remarkably, despite its potentially protective effect, the level of antimicrobial activity in the investigated sputa correlated inversely with patient outcome, most likely because disease severity outweighed the beneficial antimicrobial activities.
From big data mining to technical sport reports: the case of inertial measurement units

The inertial measurement units (IMU) are instruments used to quantify the external load of athletes; they are increasingly common in assessing team and individual sports. This type of instruments has several sensors, such as accelerometers, gyroscopes and magnetometers; this allows access to a large amount of information and analysis possibilities. Due to the complexity of synthesising this data, it is necessary to create a flow for collecting, analysing and presenting the collected data in a simple way and present it as quickly as possible to the technical staff. This report aims to present new methods of reduction of the data and propose a new approach method for the analysis of the IMU’s outcomes.
Root colonization by endophytic insect‐pathogenic fungi

Several ascomycetous insect‐pathogenic fungi, including species in the genera Beauveria and Metarhizium, are plant root symbionts/endophytes and are termed as endophytic insect‐pathogenic fungi (EIPF). The endophytic capability and insect pathogenicity of Metarhizium are coupled to provide an active method of insect‐derived nitrogen transfer to plant hosts via fungal mycelia. In exchange for the insect‐derived nitrogen, the plant provides photosynthate to the fungus. This symbiotic interaction offers other benefits to the plant—EIPF can improve plant growth, they are antagonistic to plant pathogens and herbivores and can enhance the plant tolerance to abiotic stresses. The mechanisms and underlying biochemical and genetic features of insect pathogenesis are generally well‐established. However, there is a paucity of information regarding the underlying mechanisms in this plant‐symbiotic association. Here we review five aspects of EIPF interactions with host plant roots: (i) rhizosphere colonization, (ii) signalling factors from the plant and EIPF, (iii) modulation of plant defence responses, (iv) nutrient exchange and (v) tripartite interactions with insects and other micro‐organisms. The elucidation of these interactions is fundamental to understanding this symbiotic association for effective application of EIPF in an agricultural setting.
Co-expression of cellulase and xylanase genes in Sacchromyces cerevisiae toward enhanced bioethanol production from corn stover

ABSTRACT Lignocellulose is considered as a good resource for producing renewable energy. Previous in vitro studies have shown the synergistic action between cellulase and xylanase during lignocellulose biohydrolysis. In order to achieve the same effect in S. cerevisiae to enhance the practical biotransformation, two recombinant Saccharomyces cerevisiae strains (INVSc1-CBH-CA and INVSc1-CBH-TS) with co-expressed cellulase and xylanase were constructed. The cellulase and xylanase activities in INVSc1-CBH-CA and INVSc1-CBH-TS were 716.43 U/mL and 205.13 U/mL, 931.27 U/mL and 413.70 U/mL, respectively. The recombinant S. cerevisiae can use the partly delignified corn stover (PDCS) more efficiently and more ethanol producted than S. cerevisiae only expressing cellulase. Fermentation with INVSc1-CBH-CA and INVSc1-CBH-TS using PDCS ethanol yields increased by 1.7 and 2.1 folds higher than INVSc1-CBH, 2.8 and 3.4 folds higher than the wild type S. cerevisiae. The strategy of co-expression cellulase and xylanase in saccharomyces cerevisiae is effective and can be a foundation to research the mechanism of synergy effect of cellulose and xylanase.

Daily interpersonal tensions and well-being among older adults: The role of emotion regulation strategies.

Interpersonal tensions are more strongly associated with well-being than other types of stressors in late life. Yet, there is little understanding of how older adults' preferences for different emotion regulation strategies may buffer or exacerbate effects of daily interpersonal tensions on emotional well-being. The present study examined links between interpersonal tensions and daily emotional well-being and whether those links were exacerbated or buffered by general emotion regulation strategy preferences. Participants were from the Daily Experiences and Well-Being Study, which included 293 older adults (aged 65 + years old) who completed baseline interviews, followed by 5-6 days of ecological momentary assessments, and a leave-behind questionnaire regarding emotion regulation strategies. Interpersonal tensions predicted poorer emotional well-being throughout the day and even more so for oldest-old individuals (aged 80 +) compared to young-old individuals. The effects of tensions on emotional well-being were attenuated among adults who generally preferred reappraisal and exacerbated among people who generally preferred avoidance. Reappraisal was particularly important for buffering the effects of tensions among individuals with poorer self-reported health. The findings regarding active coping were more nuanced and varied by age. The current study advances previous research on emotion regulation and social relations by examining older adults and revealing that links between interpersonal tensions, emotion regulation strategies, and emotional well-being vary on the basis of age and self-rated health. This study highlights the importance of considering how personal characteristics may shape later-life well-being in the context of coping with interpersonal tensions.
