Monkeypox has recently surfaced as a public health issue, and the virus has spread rapidly worldwide in the post-COVID-19 period. These emerging infections hinder human health and the advancement of the global economy. There are currently no authorized medications to treat this condition. As a result, this study gap motivates us to seek a viable inhibitor from a natural source. In the present study, 10 plant-derived compounds and commercialized drugs respectively were subjected to molecular docking and 100 ns molecular dynamics simulations to identify the potent inhibitor against MPXV E8 ectodomain protein. Punicalagin showed a greater affinity for the target protein (-9.1 kcal/mol), and maraviroc, among commercial drugs, had a binding affinity of -7.4 kcal/mol which was lower than punicalagin. MD simulations substantiated this study and showed better stability of punicalagin with the target envelope protein, compared to the control drug maraviroc. This finding was validated by decreased RMSD, RMSF, Rg, and SASA values with increased H-bonding. Therefore, we could speculate that the plant-derived natural compound, punicalagin can act as a potent therapeutic against the MPXV.

Acoustic communication in animals can be affected by multiple biotic (intra and interspecific) and abiotic (e.g., wind and rain) natural noises. In addition, human beings produce additional novel sources of noise, which can reduce or inhibit the reception of acoustic signals by conspecifics, leading to behavioral changes. In this study, we investigated whether sound of conspecifics and road noise additively affect the acoustic parameters of the advertisement call of males of a Yellow Heart-tongued Frog (Phyllodytes luteolus). We hypothesized that males that vocalize in larger choruses (many males) and in areas close to highways (anthropic noise) will increase their temporal and spectral acoustic parameters, respectively, to avoid acoustic signal masking. We recorded the vocalizations of 38 males in environments close (N=18) to and distant (N=20) from highways in different social contexts (many or few individuals in the chorus). Contrary to our expectation, the results indicated that individuals exposed to road noise had lower dominant frequency calls than those from natural areas, and that the density of males in the chorus had no influence on the acoustic parameters. Furthermore, we found a positive relationship between body size and intensity, indicating that larger individuals can emit calls that can reach greater distances. The advertisement call of Phyllodytes luteolus has a high dominant frequency, with little overlap with the frequency of anthropic noises (roads), which may explain its presence and reproductive success of this species in bromeliads from urbanized areas.

Subject: Role of Impulse Oscillometry in Children with Airway Narrowing After Bronchoscopic Stent Implantation, a Pilot Observational StudyTzung-Lin Ou1, Chieh-Ho Chen2*, Chien-Heng Lin2* and Wen-Jue Soong 2,3,4,5*1Department of Medicine, College of Medicine, China Medical University, Taichung, Taiwan2Division of Pediatric Pulmonology, China Medical University Children’s Hospital, China Medical University, Taichung, Taiwan3 Department of Pediatrics, School of Medicine, National Yang-Ming University, Taipei, Taiwan4 Department of Pediatrics, Taipei Veterans General Hospital, Taipei, Taiwan5 Department of Pediatrics, Tri-Service General Hospital, Taipei, Taiwan* Correspondence:Corresponding Author: Chieh-Ho Chen, Chien-Heng Lin and Wen-Jue Soongpedlungcmu@gmail.comKeywords: Impulse oscillometry, transbronchoscopic airway intervention, stent, obstructive lung disease, peripheral airway resistance, pulmonary function testTo the Editor,We would like to address the critical issue of congenital airway anomalies, encompassing tracheal stenosis, tracheomalacia, and tracheo-bronchomalacia, which pose life-threatening challenges. Patients afflicted with these conditions frequently exhibit respiratory distress, such as tachypnea, dyspnea, chest tightness, chronic cough, exercise intolerance, and audible breathing sounds. The risk of recurring pulmonary infections is associated with inadequate airway clearance, culminating in irreversible lung damage over time.Bronchoscopic airway stent placement emerges as an efficacious strategy for alleviating tracheo-bronchial obstructions. It demonstrates notable success in mitigating breathlessness, elevating quality of life, and enhancing survival rates, especially among adults with malignancies. However, the extension of this technique to pediatric populations remains underexplored, primarily due to concerns regarding potential complications, including hypoxia, laryngospasm, hemorrhage, and air-leak syndromes. Despite its clinical safety, the absence of established consensus or guidelines for bronchoscopy and airway stent implantation in infants and children persists (1).Nevertheless, evaluation of pulmonary function after airway stent implantation by spirometry might be challenging in pediatric population due to weak respiratory efforts, inadequate cooperation, and poor comprehension. This is where Impulse Oscillometry (IOS) comes into play. Grounded in the forced oscillation technique, IOS passively assesses airway resistance and alveolar reactance during tidal breathing. IOS is able to differentiate resistance of peripheral (small) airways from central (large) airways, thus aiding treatment planning for obstructive lung diseases. It encompasses parameters like respiratory impedance (Z), respiratory resistance (R), and respiratory reactance (X), which together provide a comprehensive analysis of airway function, assisting in the assessment of obstructive and restrictive lung diseases.

Livebearing fishes are a standard model for studying the effect of predation on prey biology. Numerous studies have found differences in life history, sexual selection, behavior, and morphology between populations of the same species that co-occur with predators and those that do not. Alfaro cultratus is a livebearing fish with populations in different predation environments, but unlike other livebearers, this species also has an extreme body shape that is laterally compressed. Given this unusual morphology, we asked if predation environment would still predict overall body shape, as has been documented in other species. We collected specimens from both predator and no-predator sites in Costa Rica. We used a geometric morphometrics analysis to determine if body shape is affected by the predation environment while controlling for size and river gradient. Body shape does indeed differ between predation environments; however, the observed differences contrast with the patterns found in other livebearer systems. Alfaro cultratus in predation environments had deeper and shorter bodies and deeper caudal peduncles than those found in environments without dominant fish predators.

Introduction: Acute viral gastroenteritis is a common illness especially in developing countries. Globally, the role of human astroviruses (HAstV) in gastroenteritis among children and elderly is well documented. But there exists a substantial dearth of information on HAstV strains circulating in Nigeria. Method: Viral like particles (VLPs) were purified from stool samples from children diagnosed with acute flaccid paralysis (AFP) between January and December 2020 from five states in Nigeria, using the NetoVIR protocol. Extracted viral RNA and DNA were subjected to a reverse transcription step, and subsequent random PCR amplification. Library preparation and Illumina sequencing were performed. Using the Virome Paired-End Reads (ViPER) pipeline, raw reads were processed into genomic contigs. Phylogenetic and pairwise identity analysis of the recovered HAstV genomes was performed. Results: Six near complete genome sequences of HAstV were identified and classified as HAstV 4 (n=1), HAstV5 (n=1), HAstV8 (n=1) and MLB-3 (n=3). The HAstV5 belonged to a yet unclassified sub-lineage which we tentatively named HAstV-5d. Phylogenetic analysis of ORFs 1a, 1b and 2 suggested recombination events inside the MAstV1 species. Furthermore, phylogenetic analysis implied a geographic linkage between the HAstV5 strain from this study with two strains from Cameroon across all the genomic regions. Conclusion: We report for the first time the circulation of HAstV genotypes 4, 8 and MLB-3 in Nigeria and present data suggestive for the existence of a new sub-lineage of HAstV5. To further understand the burden, diversity, and evolution of HAstV increased research interest as well as robust HAstV surveillance in Nigeria is essential.

Introduction An arteriovenous fistula (AVF) in patients with end-stage kidney disease (ESKD) can influence flow states. We sought to evaluate if assessment of aortic stenosis (AS) by transthoracic echocardiographic (TTE) differs in the presence of AVF compared to other dialysis accesses in patients on dialysis. Methods We identified consecutive ESKD patients on dialysis and concomitant AS from a single center between January 2000 and March 2021. We analyzed TTE parameters of AS severity (velocities, gradients, aortic valve area [AVA]) and hemodynamics (cardiac output [CO], valvuloarterial impedance [Zva]) and compared AS parameters in patients with AVF versus other dialysis access. Results The cohort included 94 patients with co-prevalent ESKD and AS; mean age 66 years, 71% male; 43% Black, 24% severe AS. Dialysis access: 53% AVF, 47% others. In the overall cohort, no significant differences were noted between AVF vs. non-AVF in AVA/CO/Zva, but with notable subgroup differences. In mild AS, CO was significantly higher in AVF vs. non-AVF (6.3 vs. 5.2 L/min; p=0.04). In severe AS, Zva was higher in the AVF vs. non-AVF (4.6 vs. 3.6 mmHg/ml/m 2). With increasing AS severity in the AVF group, CO decreased, coupled with increase in Zva, likely counterbalancing the net hemodynamic impact of the AVF. Conclusion Among ESKD patients with AS, TTE parameters of flow states and AS severity differed in those with AVF versus other dialysis accesses and varied with progression in severity of AS. Future longitudinal assessment of hemodynamic parameters in a larger cohort of co-prevalent ESRD and AS would be valuable.

Introduction: Although it is known that antipsychotic non-compliance increases the risk of emergency department (ED) utilisation, presentation with agitation/aggression and rehospitalisation in schizophrenia spectrum disorders (SSD) patients, it is unwell known whether antipsychotic monotherapy vs. polypharmacy differs in terms of efficacy in these domains. This study aimed to determine the effectiveness of antipsychotic monotherapy and polypharmacy for the prevention of hospitalisation who admitted to the ED in the real-world. Methods: The study was conducted with electronic health records of 669 SSD patients admitted to the ED between 2019 and 2022. Patients were evaluated in four groups according to antipsychotic use at the first admission to the ED: antipsychotic non-compliance for more than 90 days, antipsychotic non-compliance for 15-90 days, antipsychotic monotherapy and polypharmacy. All antipsychotics and other psychotropic drugs used by the patients were also recorded and followed up for at least one year after index admission. Results: The groups, including patients with antipsychotic non-compliance, had higher ED visits, more hospitalisations and more admissions with agitation/aggression compared to antipsychotic monotherapy or polypharmacy. However, no differences were found between monotherapy and polypharmacy groups regarding these outcomes. Patients discharged with monotherapy or polypharmacy also had similar re-hospitalisation rates at follow-up. Conclusions: There is no positive evidence that recommending polypharmacy over antipsychotic monotherapy is superior in the frequency of ED visits, ED admissions with agitation/aggression, hospitalisation and re-hospitalisation. In this context, it may be more feasible to clozapine monotherapy before antipsychotic polypharmacy in treatment-resistant patients due to more significant evidence.

Aim: This retrospective study aimed to determine whether different renal function estimation formulas affect the incidence of venous thromboembolism (VTE) and bleeding when anticoagulant dosages are determined. Methods: The study included patients who underwent lower-limb orthopedic surgery and were treated with anticoagulants between January 2017 and March 2020 at Yaizu City Hospital. The appropriateness of anticoagulant dosing was assessed using creatinine clearance (CCr), estimated glomerular filtration rate (eGFR), and de-indexed eGFR without correction for body surface area, and the incidence of VTE and bleeding was compared among the different renal function estimation formulas. Results: The median values for body surface area, CCr, eGFR, and de-indexed eGFR were 1.40m2, 56.0mL/min, 73.0mL/min/1.73m2, and 60.9mL/min, respectively. There was no significant difference in the incidence of VTE among the different renal function estimation formulas. However, when the threshold for dose reduction or contraindication was determined by eGFR rather than CCr, the incidence of bleeding was significantly higher in the group that was overdosed in CCr (6.0% vs 25.7% p<0.05). Similarly, when the threshold for dose reduction or contraindication was determined by de-indexed eGFR rather than CCr, the incidence of bleeding was significantly higher in the group that was overdosed in CCr (7.5% vs 28.6% p<0.05). Conclusion: It is necessary to set the dosage of anticoagulants based on CCr for patients with a small body surface area in the field of orthopedics to avoid the risk of bleeding.

Background: The purpose of pharmacovigilance is the timely detection and identification of harmful drug-related reactions in the clinical application of drugs to reduce the risk of their clinical use. Macitentan has been on the market for close to 10 years, during which time several clinical studies have reported adverse events associated with macitentan outside of the drug description and uploaded them into the U.S. Food and Drug Administration’s (FDA) Adverse Event Reporting System.Aim: This study aimed to promote the safe use of macitentan by mining and analyzing the adverse event signals of macitentan in the FAERS database.Method： The proportionate disequilibrium method was used to mine and analyze the FAERS database for macitentan-related adverse events. Preferred Terms of ADR reports were categorized by System Organ Class (SOC) based on the Medical Dictionary for Regulatory Activities. Results： A total of 32,607 macitentan adverse events were retrieved, and after exclusion by the methodology developed in this study, a total of 253 positive signals for AEs were obtained, and it was found that macitentan may have potential new adverse reactions such as blood potassium decreased(ROR [95% CI]= 3.51[3.10-3.98]), respiratory failure(ROR [95% CI]=4.06[3.77-4.39]), epistaxis(ROR [95% CI]=2.50[2.29-2.73]), and other potential adverse reactions in addition to the adverse reactions that have already been reported in the specification.Conclusion: Clinical attention is recommended for the new adverse drug reactions to macitentan detected in this study.

Dengue fever and Scrub typhus co-infection deteriorating Severe Acute Cholangitis: A rare case report

Objective: Intravenous leiomyomatosis (IVL) features histologically benign smooth muscle tumors growing within blood vessels. Although surgery is the primary treatment method, the rate of postoperative recurrence is high. This study aimed to analyze the risk factors for postoperative recurrence or progression of IVL and explore the impact of different treatment strategies on prognosis. Design: A retrospective cohort study of IVL patients who received surgical treatment was performed. Setting: A referral center for difficult and critical diseases in Obstetrics and Gynecology in China (Beijing). Population or sample: 114 IVL patients who received surgical treatment from January 2011 to December 2022 and received follow-up for ≥ 3 months were enrolled. Methods: Risk factors for postoperative recurrence or progression of IVL was analyzed by Kaplan‒Meier survival analysis. Sub-group analysis, including IVL confined to the uterus and para-uterine vessels, and IVL involving the iliac vein/genital vein and the proximal veins, was performed to explore impact of different treatment strategies on prognosis. Main outcome measures: The primary endpoint was recurrence (for patients with complete resection) or progression (for patients with incomplete resection). Results: The median follow-up time was 24 months (range 3-132 months). Twenty-nine cases (25.4%) recurred or progressed. The median recurrence or progression time was 16 months (range 3-60 months), and the median progression free survival time was not reached. Incomplete tumor resection (P=0.019), involvement of the iliac vein or genital vein (P=0.042), involvement of the inferior vena cava (P=0.025), and size of pelvic tumor ≥ 15 cm (P=0.034) were risk factors for recurrence and progression. For IVL confined to the uterus or para-uterine vessels, the postoperative recurrence rate after hysterectomy and bilateral oophorectomy was low. Compared to hysterectomy and bilateral oophorectomy, the recurrence risk after tumorectomy was significantly increased (P=0.009), and the recurrence risk after hysterectomy was marginally increased (P=0.058). For IVL involving the iliac vein/genital vein and the proximal veins, postoperative aromatase inhibitor treatment (P=0.889) and two-stage surgery (P=0.862) were not risk factors for recurrence on the premise of complete tumor resection. Conclusion: Incomplete tumor resection, extent of tumor lesions and size of the pelvic tumor were risk factors for postoperative recurrence and progression of IVL. For IVL confined to the uterus and para-uterine vessels, the recurrence rate after hysterectomy and bilateral oophorectomy was low. For IVL involving the iliac vein/genital vein and the proximal veins, aromatase inhibitor treatment after complete tumor resection did not reduce the risk of recurrence.

Background: Complex Regional Pain Syndrome (CRPS) is a multifactorial and often refractory condition that involves hyperalgesia and allodynia of the extremities. Current treatments are mostly limited and short-lived, thus different modalities of interventional pain control, have come up to play a significant role in the management of CRPS. Objectives: The aim of this article is to present a single case from a Multidisciplinary Pain Management Center, regarding a wireless peripheral nerve stimulation (WPNS) treatment for a type II CRPS. Methods: The EORTC QLQ-C30 and NHP questionnaires were used as tools, during an eighteenth month period follow-up. Results: A 43-year-old healthy woman, diagnosed with ganglionar tuberculosis and a refractory type II CRPS in the right upper extremity, following an excisional biopsy. She underwent placement of a permanent electrode in the right ulnar nerve. During eighteen months, a progressive reduction of pain medication was also achieved and an improvement in her quality of life associated to a remarkable relief in pain, allodynia and temperature impairment. Conclusions: Given its high acceptance, safety and potential to influence the neuronal plasticity, WPNS thus shows to be a promising and favorable tool in the multidisciplinary approach of CRPS.

Several midbrain nuclei degenerate in Parkinson’s Disease. Many of these nuclei share the common characteristics that are thought to contribute to their selective vulnerability, including pacemaking activity and high levels of calcium influx. In addition to the well-characterized dopaminergic neurons of the substantia nigra pars compacta (SNc), the cholinergic neurons of the pedunculopontine nucleus (PPN) also degenerate in PD. It is well established that the low-threshold L-type calcium current is a main contributor to tonic calcium in SNc dopaminergic neurons and is hypothesized to contribute to their selective vulnerability. However, it is not yet clear whether the vulnerable PPN cholinergic neurons share this property. Therefore, we used two-photon dendritic calcium imaging and whole-cell electrophysiology to evaluate the role of L-type calcium channels in the tonic and phasic activity of PPN neurons and the corresponding dendritic calcium signal and directly compare these characteristics to SNc neurons. We found that blocking L-type channels reduces tonic firing rate and dendritic calcium levels in SNc neurons. By contrast, the calcium load in PPN neurons during pacemaking did not depend on L-type channels. However, we find that blocking L-type channels reduces phasic calcium influx in PPN dendrites. Together, these findings show that L-type calcium channels play different roles in the activity of SNc and PPN neurons, and suggest that low-threshold L-type channels are not responsible for tonic calcium levels in PPN cholinergic neurons and are therefore not likely to be a source of selective vulnerability in these cells.

Dopaminergic (DA) neurons play pivotal roles in diverse brain functions, spanning movement, reward processing, and sensory perception. DA neurons are most abundant in the midbrain (Substantia Nigra pars compacta, SNC, and Ventral Tegmental Area, VTA) and the olfactory bulb (OB) in the forebrain. Interestingly, a subtype of OB DA neurons is capable of regenerating throughout life, while a second class is exclusively born during embryonic development. Emerging evidence in SNC and VTA also indicates substantial heterogeneity in terms of morphology, connectivity, and function. To further investigate this heterogeneity and directly compare form and function of midbrain and forebrain DA neurons, we performed immunohistochemistry and whole-cell patch-clamp recordings in ex vivo brain slices from juvenile DAT-tdTomato mice. After confirming the penetrance and specificity of the dopamine transporter (DAT) Cre line, we compared soma shape, passive membrane properties, voltage sags and action potential firing across midbrain and forebrain DA subtypes. We found that each DA subgroup within midbrain and forebrain was highly heterogeneous, and that DA neurons across the two brain areas are also substantially different. These findings complement previous work in rats as well as gene expression and in vivo datasets, further questioning the existence of a single “dopaminergic” neuronal phenotype.

Objective: A prospective cohort study was conducted to investigate sleep status during the first and second trimester of pregnancy in pregnant women on adverse birth outcome, such as preterm birth (PTB), low birth weight (LBW) and small for gestational age (SGA). Design: Prospective cohort study. Setting: China. Population: Cases were singleton pregnant women aged 18-40 years from the prospective Tongji-Shuangliu Birth Cohort. Methods: Multivariable logistic regression models were used to analyze the associationof sleep status during the first and second trimester of pregnancy with adverse birth outcomes and generated the odds ratio (OR) and 95% confidence interval (CI). Main outcome measures: Birth outcomes. Results: Finally, 5,412 pregnant women were included in the analysis. In the multivariable model, compared with 8-9 hours/night, sleep less than 7 hours/night during second trimester increases the risk of PTB (OR: 1.80, 95% CI: 1.12,2.89), and the risk of PTB was decreased in pregnant women who slept ≥11 hours/night (OR: 0.53, 95% CI: 0.30,0.93). Sleep quality, napping and sleep changes in the first and second trimesters, and sleep duration in the first trimester were not statistically associated with PTB, LBW and SGA. Conclusions: Short sleep duration during pregnancy is associated with a higher risk of PTB, while longer sleep duration at night is associated with a lower risk of PTB. Sleep status during pregnancy was not associated with LBW and SGA. In order to reduce risk of adverse birth outcomes, sleep problems in pregnant women should be strengthened during pregnancy care.

Objective: Many women suffer from migraines, regardless of their menstrual cycle. This study aimed to determine the effect of laughter therapy on women with migraine. Design: This is a randomized controlled study to determine the effect of laughter therapy on migraine. Setting: Single center in Turkey. Population: 52 women with migraine. Materials and methods: This randomized controlled study was carried out with 52 female students with migraine (control: 28, experimental: 24) studying in the faculty of health sciences of a university. The sample was randomly divided into two groups using the draw lots method. The experimental group received 20-30-minute laughter therapy once a week for 8 weeks. Main outcome measures: Data were collected before and after the therapy using an Individual Identification Form created by the researchers, the Visual Analog Scale, and the Psychological Well-Being Scale. Results: There was no significant difference between the experimental and control groups in terms of the Psychological Well-Being Scale (p>0.05). Eight participants in the experimental group had no headache or migraine attack during the laughter therapy. Furthermore, there was a significant difference between the pre-therapy and post-therapy pain severity in the experimental and control groups (p<0.05). Conclusion: Laughter therapy can be effective in reducing pain and preventing migraine attacks in women with migraine.

This study proposes the GOOSE algorithm as a novel metaheuristic algorithm based on the goose’s behavior during rest and foraging. The goose stands on one leg and keeps his balance to guard and protect other individuals in the flock. The GOOSE algorithm is benchmarked on 19 well-known benchmark test functions, and the results are verified by a comparative study with genetic algorithm (GA), particle swarm optimization (PSO), dragonfly algorithm (DA), and fitness dependent optimizer (FDO). In addition, the proposed algorithm is tested on 10 modern benchmark functions, and the gained results are compared with three recent algorithms, such as the dragonfly algorithm, whale optimization algorithm (WOA), and salp swarm algorithm (SSA). Moreover, the GOOSE algorithm is tested on 5 classical benchmark functions, and the obtained results are evaluated with six algorithms, such as fitness dependent optimizer (FDO), FOX optimizer, butterfly optimization algorithm (BOA), whale optimization algorithm, dragonfly algorithm, and chimp optimization algorithm (ChOA). The achieved findings attest to the proposed algorithm’s superior performance compared to the other algorithms that were utilized in the current study. The technique is then used to optimize Welded beam design and Economic Load Dispatch Problem, three renowned real-world engineering challenges, and the Pathological IgG Fraction in the Nervous System. The outcomes of the engineering case studies illustrate how well the suggested approach can optimize issues that arise in the real-world.

Objective: Case-based reasoning predicts outcomes based on matching to training cases and without modeling the relationship between features and outcome. This study compares the accuracy of the two nearest means (2NM), a case-based reasoning, to regression, a feature-based reasoning. Data Sources: The accuracy of the two methods was examined in predicting mortality of 296,051 residents in Veterans Health Affairs nursing homes. Data was collected from 1/1/2000 to 9/10/2012. Data was randomly divided into training (90%) and validation (10%) samples. Study Design: Case-control observational study Data Collection/Extraction Methods: In the 2NM algorithm, first data was transformed so that all features are monotonely related to the outcome. Second, all means that violate monotone order were set aside; to be processed as exceptions to the general algorithm. Third, for predicting a new case, the means in the training set are divided into “excessive” and “partial” means, based on how they match a new case. Finally, the outcome for the new case is predicted as the average of two means: the excessive mean with minimum outcome and the partial mean with maximum outcome. For regression, we predicted mortality from age, gender, and 10 disabilities. Principal Findings: In cases set aside for validation, the 2NM had a McFadden Pseudo R-squared of 0.51. The linear logistic regression, trained on the same training sample and predicting to the same validation cases, had a McFadden Pseudo R-squared of 0.09. The 2NM was significantly more accurate (alpha <0.001) than linear logistic regression. Conclusions : 2NM, a Case-Based reasoning method, captured nonlinear interactions in the data.

Background: The complex interplay between the continuous infection of Helicobacter pylori (Hp) in gastric mucosa and the development of Hp–associated gastritis remains poorly understood. The interaction between the gastric epithelium and the immune response induced by Hp may be an important contributing factor. Antimicrobial peptides (AMPs) can protect the gastric mucosa from bacteria. This study aimed to investigate the effects of Hp on the gastric flora, AMP (e.g., REG3A, HBD2 and S100A9) expression and the mucosal ultrastructure in Hp-positive (Hp+) patients with gastritis. Methods: The bacterial composition was analyzed in 63 patients with gastritis using 16S rRNA sequencing. The altered expression levels of AMPs (REG3A, HBD2 and S100A9) were analyzed by RT-qPCR for quantification of AMP mRNA levels. Western blotting and immunohistochemical staining were used to investigate AMPs expressions in the gastric biopsies. Observation of the gastric ultrastructure was performed by transmission electron microscopy (TEM). Results: HP infection significantly reduced the abundance of bacteria. REG3A, S100A9, and HBD2 were highly expressed in Hp+ patients. The destruction of the epithelial cell membrane and the entry of mucus particles into the gastric lumen were observed by TEM in Hp+ patients. Conclusion: The findings reported here confirm the dysbiosis of gastric microecology and AMPs expression in gastritis patients infected with Hp. This study provides information on the complex and dynamic ecosystem and may be helpful for further research to find a treatment alternative in the post‐antibiotic era to eradicate multidrug‐resistant Hp strains.

Both maternal substance use and unpredictability of her sensory signals may affect child development, but no studies have examined them together. We explored the unpredictability, frequency, and duration of maternal sensory signals in 59 mother-child dyads, 34 with and 25 without maternal substance use. We also examined the association between unpredictability of maternal signals and children's cognitive development. Maternal sensory signals were evaluated with videorecorded dyadic free-play interactions at child age of 24 months. Children's cognitive development was evaluated with Bayley-III at 24 months and with WPPSI-III at 48 months. We found no differences in sensory signals between substance-using and non-using mothers. Higher unpredictability of maternal sensory signals was associated with poorer child cognitive and language development at 24 months and with poorer nonverbal reasoning at 48 months. Unpredictability of maternal sensory signals may be a vital parenting aspect shaping children's development, but more research is needed in high-risk groups.
