The role of the probiotic Akkermansia muciniphila in brain functions: insights underpinning therapeutic potential

Abstract The role of Akkermansia muciniphila, one of the most abundant microorganisms of the intestinal microbiota, has been studied extensively in metabolic diseases, such as obesity and diabetes. It is considered a next-generation probiotic microorganism. Although its mechanism of action has not been fully elucidated, accumulating evidence indicates the important role of A. muciniphila in brain functions via the gut-brain axis and its potential as a therapeutic target in various neuropsychiatric disorders. However, only a limited number of studies, particularly clinical studies, have directly assessed the therapeutic effects of A. muciniphila interventions in these disorders. This is the first review to discuss the comprehensive mechanism of A. muciniphila in the gut-brain axis via the protection of the intestinal mucosal barrier and modulation of the immune system and metabolites, such as short-chain fatty acids, amino acids, and amino acid derivatives. Additionally, the role of A. muciniphila and its therapeutic potential in various neuropsychiatric disorders, including Alzheimer’s disease and cognitive deficit, amyotrophic lateral sclerosis, Parkinson’s disease, and multiple sclerosis, have been discussed. The review suggests the potential role of A. muciniphila in healthy brain functions.
Transmission dynamics and epidemiological characteristics of SARS-CoV-2 Delta variant infections in Guangdong, China, May to June 2021

Background The Delta variant of SARS-CoV-2 had become predominant globally by November 2021. Aim We evaluated transmission dynamics and epidemiological characteristics of the Delta variant in an outbreak in southern China. Methods Data on confirmed COVID-19 cases and their close contacts were retrospectively collected from the outbreak that occurred in Guangdong, China in May and June 2021. Key epidemiological parameters, temporal trend of viral loads and secondary attack rates were estimated. We also evaluated the association of vaccination with viral load and transmission. Results We identified 167 patients infected with the Delta variant in the Guangdong outbreak. Mean estimates of latent and incubation period were 3.9 days and 5.8 days, respectively. Relatively higher viral load was observed in infections with Delta than in infections with wild-type SARS-CoV-2. Secondary attack rate among close contacts of cases with Delta was 1.4%, and 73.1% (95% credible interval (CrI): 32.9–91.4) of the transmissions occurred before onset. Index cases without vaccination (adjusted odds ratio (aOR): 2.84; 95% CI: 1.19–8.45) or with an incomplete vaccination series (aOR: 6.02; 95% CI: 2.45–18.16) were more likely to transmit infection to their contacts than those who had received the complete primary vaccination series. Discussion Patients infected with the Delta variant had more rapid symptom onset compared with the wild type. The time-varying serial interval should be accounted for in estimation of reproduction numbers. The higher viral load and higher risk of pre-symptomatic transmission indicated the challenges in control of infections with the Delta variant.
The Production Effect Interacts With Serial Positions

Abstract: Reading some words aloud during presentation, that is, producing them, and reading other words silently generate a large memory advantage for words that are produced. This robust within-list production effect is in contrast with the between-lists condition in which all words are read aloud or silently. In a between-lists condition, produced items are better recognized, but not better recalled. The lack of a between-lists production effect with recall tasks has often been presented as one of its defining characteristics and as a benchmark for evaluating models. Recently, Cyr et al. (2021) showed that this occurs because item production interacts with serial positions: Produced items are less well recalled on the first serial positions than silently read items, while the reverse pattern is observed for the recency portion of the curve. However, this pattern was observed with a repeated-measures design, and it may be a by-product of compensatory processes under the control of participants. Here, using a between-participants design, we observed the predicted interaction between production and serial positions. The results further support the Revised Feature Model (RFM) suggesting that produced items are encoded with more modality-dependent distinctive features, therefore benefiting recall. However, the production of the additional distinctive features would disrupt rehearsal.
Global incidence and mortality of hepatitis B and hepatitis C acute infections, cirrhosis and hepatocellular carcinoma from 2010 to 2019

Hepatitis B virus (HBV) and hepatitis C virus (HCV) contribute to significant healthcare burden globally. We aim to provide an updated and comprehensive analysis of global trends in the incidence and mortality of HBV and HCV related acute infections, cirrhosis and hepatocellular carcinoma (HCC). Estimates of annual cause‐specific disease incidence and mortality for HBV and HCV were analysed using the 2010–2019 Global Burden of Diseases, Injuries and Risk Factors Study database. Three distinct disease states were evaluated: acute infections, cirrhosis and HCC. Age‐standardized disease incidence and mortality were presented per 100,000 population and stratified by age, sex, year and 21 world regions. From 2010 to 2019, overall incidence of acute HBV declined by 19.3% (95% CI 4.1–32.0, p < .05) and HBV cirrhosis declined by 15.0% (95% CI 9.8–20.7, p < .05). Incidence of HCV cirrhosis increased by 5.6% (95% CI 0.3–10.2, p < .05) and HCV HCC remained stable. Incidence of acute HCV declined until 2015, after which it began increasing. From 2010 to 2019, overall mortality for HBV cirrhosis and HCV cirrhosis declined, whereas mortality for acute infections and HCC remained stable. Major differences in HBV and HCV incidence and mortality trends were observed when stratified by world regions. In conclusion, while our analyses of global trends in HBV and HCV incidence and mortality demonstrate encouraging trends, disparities in disease epidemiology were observed across world regions. These observations will identify regions and populations where greater focus and resources are needed to continue progressing towards viral hepatitis elimination.
Ultrasound Guided Biopsy in Patients With HPV‐Associated Oropharyngeal Squamous Cell Carcinoma

To identify the differences in sensitivity and accuracy between ultrasound‐guided and palpation‐guided fine needle aspirations (FNA) of suspicious lymph nodes in patients with human papillomavirus (HPV) (+) oropharyngeal squamous cell carcinoma (OPSCC). Additional objectives included identifying patient specific factors affecting biopsy accuracy and evaluating potential differences in accuracy between fine and core needle biopsies.
Decoding motor expertise from fine‐tuned oscillatory network organization

Can motor expertise be robustly predicted by the organization of frequency‐specific oscillatory brain networks? To answer this question, we recorded high‐density electroencephalography (EEG) in expert Tango dancers and naïves while viewing and judging the correctness of Tango‐specific movements and during resting. We calculated task‐related and resting‐state connectivity at different frequency‐bands capturing task performance (delta [δ], 1.5–4 Hz), error monitoring (theta [θ], 4–8 Hz), and sensorimotor experience (mu [μ], 8–13 Hz), and derived topographical features using graph analysis. These features, together with canonical expertise measures (i.e., performance in action discrimination, time spent dancing Tango), were fed into a data‐driven computational learning analysis to test whether behavioral and brain signatures robustly classified individuals depending on their expertise level. Unsurprisingly, behavioral measures showed optimal classification (100%) between dancers and naïves. When considering brain models, the task‐based classification performed well (~73%), with maximal discrimination afforded by theta‐band connectivity, a hallmark signature of error processing. Interestingly, mu connectivity during rest outperformed (100%) the task‐based approach, matching the optimal classification of behavioral measures and thus emerging as a potential trait‐like marker of sensorimotor network tuning by intense training. Overall, our findings underscore the power of fine‐tuned oscillatory network signatures for capturing expertise‐related differences and their potential value in the neuroprognosis of learning outcomes.
Evaluating the level of physical transformation of houses in gated communities in Ghana

The upsurge of real estate housing within Accra has resulted in all manner of gated communities springing up across the city scape. These seek to provide housing services to the desperate urban dweller. The quality of their services has however been brought to question due to lack of a proper regulatory body to oversee their work. Recent studies indicate the emergence of physical transformations. This research sought to investigate the conditions and reasons underlying these housing transformations. A case study approach, with a mix of both qualitative and quantitative methods were adopted in determining the conditions of the houses. The relative important index was also used in ranking the various factors that led to these physical transformations. The study revealed that 41% of the houses have undergone transformations with external works, fenetrations, and mechanical and engineering services being most parts affected. Major reasons given for transformation were poor ventilation and lighting. The study recommends amongst others that the government should institute a special regulatory body backed by law with regular assessment from the occupants in order to check the performance of real estate developers.

Systematic review and narrative synthesis of computerized audit and feedback systems in healthcare

Abstract Objectives (1) Systematically review the literature on computerized audit and feedback (e-A&F) systems in healthcare. (2) Compare features of current systems against e-A&F best practices. (3) Generate hypotheses on how e-A&F systems may impact patient care and outcomes. Methods We searched MEDLINE (Ovid), EMBASE (Ovid), and CINAHL (Ebsco) databases to December 31, 2020. Two reviewers independently performed selection, extraction, and quality appraisal (Mixed Methods Appraisal Tool). System features were compared with 18 best practices derived from Clinical Performance Feedback Intervention Theory. We then used realist concepts to generate hypotheses on mechanisms of e-A&F impact. Results are reported in accordance with the PRISMA statement. Results Our search yielded 4301 unique articles. We included 88 studies evaluating 65 e-A&F systems, spanning a diverse range of clinical areas, including medical, surgical, general practice, etc. Systems adopted a median of 8 best practices (interquartile range 6–10), with 32 systems providing near real-time feedback data and 20 systems incorporating action planning. High-confidence hypotheses suggested that favorable e-A&F systems prompted specific actions, particularly enabled by timely and role-specific feedback (including patient lists and individual performance data) and embedded action plans, in order to improve system usage, care quality, and patient outcomes. Conclusions e-A&F systems continue to be developed for many clinical applications. Yet, several systems still lack basic features recommended by best practice, such as timely feedback and action planning. Systems should focus on actionability, by providing real-time data for feedback that is specific to user roles, with embedded action plans. Protocol Registration PROSPERO CRD42016048695.
Brain oxygenation during multiple sets of isometric and dynamic resistance exercise of equivalent workloads: Association with systemic haemodynamics

ABSTRACT Brain function relies on sufficient blood flow and oxygen supply. Changes in cerebral oxygenation during exercise have been linked to brain activity and central command. Isometric- and dynamic-resistance exercise-(RE) may elicit differential responses in systemic circulation, neural function and metabolism; all important regulators of cerebral circulation. We examined whether (i) cerebral oxygenation differs between isometric- and dynamic-RE of similar exercise characteristics and (ii) cerebral oxygenation changes relate to cardiovascular adjustments occurring during RE. Fourteen men performed, randomly, an isometric-RE and a dynamic-RE of similar characteristics (bilateral-leg-press, 2-min×4-sets, 30% of maximal-voluntary-contraction, equivalent tension-time-index/workload). Cerebral-oxygenation (oxyhaemoglobin-O2Hb; total haemoglobin-tHb/blood-volume-index; deoxyhemoglobin-HHb) was assessed by NIRS and beat-by-beat haemodynamics via photoplethysmography. Cerebral-O2Hb and tHb progressively increased from the 1st to 4th set in both RE-protocols (p < 0.05); HHb slightly decreased (p < 0.05). Changes in NIRS-parameters were similar between RE-protocols within each exercise-set (p = 0.91–1.00) and during the entire protocol (including resting-phases) (p = 0.48–0.63). O2Hb and tHb changes were not correlated with changes in systemic haemodynamics. In conclusion, cerebral oxygenation/blood-volume steadily increased during multiple-set RE-protocols. Isometric- and dynamic-RE of matched exercise characteristics resulted in similar prefrontal oxygenation/blood volume changes, suggesting similar cerebral haemodynamic and possibly neuronal responses to maintain a predetermined force.
Toxicity induced by ciprofloxacin and enrofloxacin: oxidative stress and metabolism

Abstract Ciprofloxacin (CIP) (human use) and enrofloxacin (ENR) (veterinary use) are synthetic anti-infectious medications that belong to the second generation of fluoroquinolones. They have a wide antimicrobial spectrum and strong bactericidal effects at very low concentrations via enzymatic inhibition of DNA gyrase and topoisomerase IV, which are required for DNA replication. They also have high bioavailability, rapid absorption with favorable pharmacokinetics and excellent tissue penetration, including cerebral spinal fluid. These features have made them the most applied antibiotics in both human and veterinary medicine. ENR is marketed exclusively for animal medicine and has been widely used as a therapeutic veterinary antibiotic, resulting in its residue in edible tissues and aquatic environments, as well as the development of resistance and toxicity. Estimation of the risks to humans due to antimicrobial resistance produced by CIP and ENR is important and of great interest. Moreover, in rare cases due to their overdose and/or prolonged administration, the development of CIP and ENR toxicity may occur. The toxicity of these fluoroquinolones antimicrobials is mainly related to reactive oxygen species (ROS) and oxidative stress (OS) generation, besides metabolism-related toxicity. Therefore, CIP is restricted in pregnant and lactating women, pediatrics and elderly similarly ENR do in the veterinary field. This review manuscript aims to identify the toxicity induced by ROS and OS as a common sequel of CIP and ENR. Furthermore, their metabolism and the role of metabolizing enzymes were reported.
Inherited retinal dystrophies in a Kuwaiti tribe

ABSTRACT Purpose To evaluate the clinical and genetic spectrum of inherited retinal diseases (IRDs) in a Kuwaiti tribe. Methods Forty four patients with IRDs from 28 nuclear families from the tribe, were evaluated for presenting symptoms, visual acuity, fundus examination, OCT, microperimetry, full-field (ff), and multifocal electroretinography (mERG) and genotyping. Results Seventeen patients were diagnosed with autosomal recessive retinitis pigmentosa (arRP) associated with RP1 c.606C>A with onset of nictalopia in the third decade, myopia, and macular atrophy by the age of 50; eleven with autosomal recessive cone/rod dystrophy or macular dystrophy associated with RP1 c.606C>A (p.Asp202Glu) mutation with color and central vision deterioration in teenage, myopia, paracentral ring scotoma and macular atrophy; eleven were with arRP associated with PDE6B c.992 + 1 G > A mutation with onset around 5 years, myopia, cataract, retained central fixation, and ellipsoid zone and late perimacular atrophy; five—with Leber congenital amaurosis associated with homozygous RPGRIP1 for c.1107delA mutation with extinguished ffERG and electrophysiological phenotype of rod and cone; and one patient—with autosomal recessive rod-cone dystrophy associated with homozygous PDE6B c.992 + 1 G > A, who was homozygous ABCA4 c.5882 G > A and heterozygous EYS; c.2137 + 1 G > A. Conclusions This study represents a typical tribe from the Middle East with high rate of consanguinity for many generations that harbors multiple mutated genes associated with IRD. It demonstrates the predominant phenotype and its variability in retinal disorders caused by identical mutations and illustrates the nuances in the clinical presentation and disease progression of patients with pathogenic mutations in more than one gene.
The roles and potential mechanisms of HCST in the prognosis and immunity of KIRC via comprehensive analysis.

OBJECTIVES Hematopoietic cell signal transducer (HCST) participates in the activation of phosphatidylinositol 3 kinase-dependent signaling pathway and in the natural killer (NK) and T cell responses, which affect cell survival and proliferation. Here, the values of HCST in kidney renal clear cell carcinoma (KIRC) are analyzed. METHODS We used GEO, TCGA, GEPIA, UALCAN and TIMER databases to profile the expression of HCST in KIRC tissues, and define its clinical roles. The biological functions and signaling mechanisms modulated by HCST and its co-expressed genes were identified and analyzed via the GO and KEGG databases. On the other hand, the potential value of HCST expression in KIRC immunity was explored using the TIMER and GEPIA databases. RESULTS Our analysis demonstrated that HCST is significantly overexpressed in KIRC tissues. The upregulation of HCST is associated with clinical stage, tumor grade, tissue subtype and poor prognosis of KIRC patients. Increased HCST expression might be involved in signaling pathways such as antigen processing and presentation, cell adhesion molecules, cytokine-cytokine receptor, chemokine signaling pathway, T cell receptor signaling pathway, FC gammar mediated phagocytosis and B cell receptor signaling pathway. In addition, the expression of HCST was significantly correlated with the levels of KIRC purity, B cells, CD8+ T Cell, CD4+ T cells, macrophages, neutrophils and dendritic cells (DC). Furthermore, the HCST expression is associated with levels of immune infiltration B cells, CD8+ T Cell, CD4+ T cells, macrophages, neutrophils and DC. CONCLUSIONS Our data demonstrated that HCST could be a potential prognostic biomarker, and is related to the immune infiltration in KIRC.
Adherence to Pelvic Floor Physical Therapy Referrals in Women With Fecal Incontinence

Objectives This study aimed to determine the incidence of patient adherence with prescribed pelvic floor physical therapy (PFPT) in women presenting with fecal incontinence (FI) and to describe patient characteristics associated with nonadherence. Methods This is a retrospective cohort study of women presenting with FI who were prescribed PFPT between January 2010 and December 2019. Adherence with PFPT was defined as either completion of documented recommended physical therapy sessions or discharge from therapy by the therapist before completion of the prescribed sessions. Results Complete data were available for 248 patients. A total of 159 (64.1%) patients attended at least 1 session of PFPT. Patients who did not attend any sessions were more likely to have a concurrent diagnosis of pelvic organ prolapse (69.7% vs 55.3%, P = 0.03). When controlled for confounding variables, concurrent prolapse remained associated with nonattendance (adjusted odds ratio of 1.9 [95% confidence interval, 1.0–3.3]). Of the patients who attended PFPT, the adherence rate was 32.7% (n = 50), whereas the rate was 20% for the total cohort. Nonadherent patients were more likely to have a higher body mass index (28.9 vs 26.9, P = 0.02), but this was no longer statistically significant once other patient characteristics were controlled for. Of the entire cohort, 136 (54.8%) followed up with their physicians after the initial referral to PFPT. Of the 59 patients, 43.7% were offered second-line therapy. Conclusion Of the women prescribed PFPT for a diagnosis of FI, approximately two thirds attended at least a single session, but only one third of those patients were adherent with the recommended therapy.
Post-arthrolysis rehabilitation in a patient with wrist stiffness secondary to distal radio-ulnar fracture: A case report

ABSTRACT Background Arthrolysis is usually performed when stiffness has a disabling effect on quality of life and in cases where physiotherapy has not been effective. This report describes one patient with a chronic stiff wrist who underwent open arthrolysis. The purpose of this case report is to describe the rehabilitation following arthrolysis, in order to illustrate the effects of intensive physiotherapy for this patient. Case Description A 54-year-old woman with chronic wrist stiffness secondary to a radio-ulnar fracture was described. The patient presented severe pain and unsatisfactory wrist range of motion and muscle strength almost 2 years after the traumatic event. Intervention Post-arthrolysis rehabilitation was based on edema control, manual therapy, transcutaneous electrical nerve stimulation (TENS), static splinting and strengthening exercises. In addition, graded motor imagery and proprioceptive rehabilitation were included to address impaired motor control. Outcome measures of passive range of motion (PROM), active range of motion (AROM), grip and pinch strength, numeric rating scale (NRS), disability of the arm, shoulder and hand (DASH) and patient-rated wrist/hand evaluation (PRWHE) were recorded. Conclusions The outcomes of this case report suggest that arthrolysis combined with immediate and intensive physiotherapy were a suitable option for the treatment of post-traumatic wrist stiffness in this patient. The passive motion measured intraoperatively was maintained, while pain, functional active motion and strength were improved allowing for social reintegration.
