Effectiveness of fecal microbiota transplant for the treatment of <fi>Clostridioides difficile</fi> diarrhea: a systematic review and metaâ•’analysis

Significance and impact of the study: In the era of antimicrobial resistance, infections due to Clostridioides difficile are on the rise. In this review we examine the use of FMT as a possible avenue to fight gastrointestinal infections produced by C. difficile. Published studies in this field vary greatly in design and outcome variables, leading to ambiguity when considering their clinical application. We believe that there is a significant lack of objective systematic reviews to inform clinical decision-making. Our objective is to evaluate the overall effectiveness and safety of FMT, as well as possible differences in effectiveness on the bases of the administration route employed.
Investigating the outcomes of cardiopulmonary resuscitation and factors affecting it: A cross‐sectional study at Dr. Moaven Hospital, Sahneh City from 2014 to 2021

Cardiopulmonary resuscitation (CPR) is referred to an attempt to maintain the respiratory system and blood circulation active to oxygenate the body's important organs until the heart and blood circulation system return to normal. CPR results are influenced by a variety of circumstances and factors. The purpose of this study was to look into the outcomes of CPR and the factors that influence them at the Dr. Moaven Hospital in Sahneh.
Large X‐effects are absent in torrent frogs with nascent sex chromosomes

Sex chromosomes are popularized as a special role in driving speciation. However, the empirical evidence from natural population processes has been limited to organisms with degenerated sex chromosomes, where hemizygosity is mainly considered to act as the driver of reproductive isolation. Here, we examined several hybrid zones of torrent frog Amolops mantzorum species complex, using an approach by mapping species‐diagnostic loci onto the reference genome to compare sex‐linked versus autosomal patterns of introgression. We find little support in sex‐linked incompatibilities for large X‐effects for these populations in hybrid zones with homomorphic sex chromosomes, due to the absence of the hemizygous effects. As expected, the large X‐effects were not found in those with heteromorphic but newly evolved sex chromosomes, owing to the absence of strong genetic differences between X and Y chromosomes. The available data so far on amphibians suggest little role for sex‐linked genes in speciation. The large X‐effects in those with nascent sex chromosomes may not be as ubiquitous as presumed across the animal kingdom.
Potential analgesic effects of psychedelics on select chronic pain conditions: A survey study

Chronic pain is a major cause of suffering and disability and is often associated with psychiatric complications. Current treatments carry the risk of severe side effects and may lead to limited or no relief at all in a relevant portion of this patient population. Preliminary evidence suggests that classical psychedelics (e.g. LSD and psilocybin) may have analgesic effects in healthy volunteers, and in certain chronic pain conditions and observational studies reveal that they are used in naturalistic settings as a means to manage pain.
Self-supervised learning with chemistry-aware fragmentation for effective molecular property prediction

Molecular property prediction (MPP) is a crucial and fundamental task for AI-aided drug discovery (AIDD). Recent studies have shown great promise of applying self-supervised learning (SSL) to producing molecular representations to cope with the widely-concerned data scarcity problem in AIDD. As some specific substructures of molecules play important roles in determining molecular properties, molecular representations learned by deep learning models are expected to attach more importance to such substructures implicitly or explicitly to achieve better predictive performance. However, few SSL pre-trained models for MPP in the literature have ever focused on such substructures. To challenge this situation, this paper presents a Chemistry-Aware Fragmentation for Effective MPP (CAFE-MPP in short) under the self-supervised contrastive learning framework. First, a novel fragment-based molecular graph (FMG) is designed to represent the topological relationship between chemistry-aware substructures that constitute a molecule. Then, with well-designed hard negative pairs, a is pre-trained on fragment-level by contrastive learning to extract representations for the nodes in FMGs. Finally, a Graphormer model is leveraged to produce molecular representations for MPP based on the embeddings of fragments. Experiments on 11 benchmark datasets show that the proposed CAFE-MPP method achieves state-of-the-art performance on 7 of the 11 datasets and the second-best performance on 3 datasets, compared with six remarkable self-supervised methods. Further investigations also demonstrate that CAFE-MPP can learn to embed molecules into representations implicitly containing the information of fragments highly correlated to molecular properties, and can alleviate the over-smoothing problem of graph neural networks.
Impact of Spatial Neglect on Activity and Participation: A Mixed-Methods Study

Post-stroke neglect is disabling, yet it is unclear whether existing assessments capture the extent neglect affects activity and participation. The objective of the study is to explore stroke survivor and caregiver perspectives on how neglect affects activity and participation and to compare their experiences to neglect assessments items. We conducted an explanatory sequential mixed-methods study by conducting semi-structured interviews with stroke survivors (n = 7) and caregivers (n = 7) analyzed using thematic analysis. Stroke survivors completed the Catherine Bergego Scale (CBS) and Behavioral Inattention Test (BIT). Descriptive analyses characterized participant’s neglect. The standardized CBS and BIT tests indicated that stroke survivors demonstrated mild-to-moderate (CBS) or no-to-mild (BIT) neglect. In contrast, the qualitative data revealed serious safety concerns and significant ongoing difficulties participating in school, work, and family activities because of neglect. Current assessments may not measure the impact of neglect on activity or participation in life for stroke survivors. Plain Language Summary Individuals with neglect after stroke experience disability. This study interviewed individuals with neglect and their caregivers to understand whether clinical assessments capture the impact that neglect has on their daily life. Results show that existing assessments may not fully measure the challenges that individuals experience.
Efficacy and safety of topical acetylcysteine combined with the use of an overcurvature-correcting device in patients with pincer nail deformity: a randomized, vehicle-controlled, investigator-blinded study

Abstract Background While pincer nails may be treated using overcurvature-correcting devices, it takes several months to achieve successful outcomes. Nail-softening drugs may reduce the treatment duration required. Objective To evaluate the efficacy and safety of treatment with acetylcysteine (AC) gel added to an overcurvature-correcting device, and define the optimal AC concentration. Methods In this investigator-blinded study, 70 patients with hallux pincer nail were fitted with an overcurvature-correcting device for 7 days and were randomly assigned to receive a single 24-h administration of a gel containing 10%, 20% or 30% AC or vehicle. Nail improvement was objectively evaluated by calculating the distal narrowed nail width (dNNW) ratio. Results All three AC concentrations plus device showed earlier sustained improvement of pincer nails versus vehicle plus device. There was no observable correlation between AC concentration and effectiveness. No clinically problematic adverse events were observed at any AC concentration, and we recommended AC gel at a concentration of 10%. Conclusions By adding AC gel application to an overcurvature-correcting device, early and sustained reductions in transverse curvature were produced compared with using a device alone (vehicle control). The dNNW ratio used in this study was an appropriate objective index for evaluating therapeutic effects.
Novel Osteochondral Biotemplate Improves Long-term Cartilage Repair Compared With Microfracture in an Ovine Model

Background: Current cartilage repair therapies do not re-create the complex mechanical interface between cartilage and bone, which is critical for long-term repair durability. New biomaterial designs that include hard tissue–soft tissue interface structures offer promise to improve clinical outcomes. Purpose/Hypothesis: The purpose of this study was to evaluate the efficacy and safety of a naturally derived osteochondral biotemplate with a novel contiguous hard tissue–soft tissue interface in an ovine model as a regenerative solution for articular cartilage defects. It was hypothesized that the osteochondral biotemplate would produce structurally superior repair tissue compared with microfracture over a 13-month period. Study Design: Controlled laboratory study. Methods: Osteochondral biotemplates were manufactured from porcine cancellous bone. Skeletally mature sheep (N = 30) were randomly allocated to 3 groups: early healing stage (euthanasia at 4 months), 6-month treatment, and 13-month treatment. In the early healing stage group, an 8 mm–diameter by 5 mm–deep osteochondral defect was created on the medial femoral condyle and treated at the time of iatrogenic injury with an osteochondral biotemplate. The contralateral limb received the same treatment 2 months later. In the 6- and 13-month treatment groups, 1 limb received the same osteochondral procedure as the early healing stage group. In the contralateral limb, an 8 mm–diameter, full-thickness cartilage defect (1-2 mm deep) was created and treated with microfracture. Cartilage repair and integration were quantitatively and qualitatively assessed with gross inspection, histological evaluation, and magnetic resonance imaging (MRI). Wilcoxon signed-rank and McNemar tests were used to compare the treatments. Results: At 6 and 13 months after treatment, the biotemplate was not present histologically. At 13 months, the biotemplate treatment demonstrated statistically higher histological scores than microfracture for integration with surrounding cartilage (biotemplate: 74 ± 31; microfracture: 28 ± 39; P = .03), type 2 collagen (biotemplate: 72 ± 33; microfracture: 40 ± 38; P = .02), total cartilage (biotemplate: 71 ± 9; microfracture: 59 ± 9; P = .01), and total integration (biotemplate: 85 ± 15; microfracture: 66 ± 20; P = .04). The osteochondral biotemplate treatment produced a notable transient nonneutrophilic inflammatory response that appeared to approach resolution at 13 months. MRI results were not statistically different between the 2 treatments. Conclusion: Even with the inflammatory response, after 13 months, the osteochondral biotemplate outperformed microfracture in cartilage regeneration and demonstrated superiority in integration between the repair tissue and host tissue as well as integration between the newly formed cartilage and the underlying bone. Clinical Relevance: This work has demonstrated the clinical potential of a novel biomaterial template to regenerate the complex mechanical interface between cartilage and the subchondral bone.
Aspects of human uterine creatine metabolism during the menstrual cycle and at term pregnancy

Abstract Creatine metabolism likely contributes to energy homeostasis in the human uterus, but whether this organ synthesizes creatine and whether creatine metabolism is adjusted throughout the menstrual cycle and with pregnancy are largely unknown. This study determined endometrial protein expression of creatine-synthesizing enzymes arginine:glycine amidinotransferase (AGAT) and guanidinoacetate methyltransferase (GAMT), creatine kinase (CKBB), and the creatine transporter (SLC6A8) throughout the menstrual cycle in fertile and primary infertile women. It also characterized creatine metabolism at term pregnancy, measuring aspects of creatine metabolism in myometrial and decidual tissue. In endometrial samples, AGAT, GAMT, SLC6A8, and CKBB were expressed in glandular and luminal epithelial cells. Except for SLC6A8, the other proteins were also located in stromal cells. Irrespective of fertility, AGAT, GAMT, and SLC6A8 high-intensity immunohistochemical staining was greatest in the early secretory phase of the menstrual cycle. During the proliferative phase, staining for SLC6A8 protein was greater (P = 0.01) in the primary infertile compared with the fertile group. Both layers of the term pregnant uterus contained creatine, phosphocreatine, guanidinoacetic acid, arginine, glycine, and methionine; detectable gene and protein expression of AGAT, GAMT, CKBB, and ubiquitous mitochondrial CK (uMt-CK); and gene expression of SLC6A8. The proteins AGAT, GAMT, CKBB, and SLC6A8 were uniformly distributed in the myometrium and localized to the decidual glands. In conclusion, endometrial tissue has the capacity to produce creatine and its capacity is highest around the time of fertilization and implantation. Both layers of the term pregnant uterus also contained all the enzymatic machinery and substrates of creatine metabolism. Summary Sentence The human uterus has the capacity to produce, transport and metabolise creatine during the menstrual cycle and at term pregnancy, with this capacity is up-regulated during the early secretory phase of the menstrual cycle.

Gender, Generations, and Guilt: Defendant Gender and Age Affect Jurors’ Decisions and Perceptions in an Intimate Partner Homicide Trial

Using the context of an intimate partner homicide trial, the study explored the effects of defendant gender and age on mock-jurors’ verdicts, sentences, and culpability ratings—and whether defendant credibility and juror anger mediate these effects. The study used a 2 (Defendant Gender: male vs. female) × 3 (Defendant Age: 25, 45, or 65 years) between-subjects design. Participants (N = 513 community members) completed the experiment online. Participants were randomly assigned to one of the six Defendant Gender × Age Conditions. Participants read the trial transcripts that included the age and gender manipulations, provided verdicts and sentences, and completed the following measures: culpability, anger, credibility, and manipulation checks. Consistent with our hypotheses mock-jurors were more likely to find the male defendant guilty and give him longer sentences than the female defendant. Additionally, when the defendant was male (vs. female) mock-jurors provided higher anger ratings and rated the defendant as more culpable in the victim’s death. Also consistent with our hypotheses, mock-jurors were more likely to find the youngest defendant guilty and view him as more culpable and less credible than the oldest defendant. The mechanisms responsible for jurors’ biased decisions varied as a function of the extra-legal variable (defendant gender vs. age). The defendant age effect was mediated by defendant credibility and the gender effect by juror anger. A defendant’s right to a fair trial is dependent on a court’s ability to limit extra-legal variables from influencing jurors’ decisions. Understanding the mechanism responsible for such bias is required before the courts can effectively remedy bias.
Efficient screening strategies for severe combined immunodeficiencies in newborns

ABSTRACT Introduction Severe combined immunodeficiency (SCID) is one of the most severe forms of inborn errors of immunity (IEI), affecting both cellular and humoral immunity. Without curative treatment such as hematopoietic stem cell transplantation or gene therapy, affected infants die within the first year of life. Due to the severity of the disease, asymptomatic status early in life, and improved survival in the absence of pretransplant infections, SCID was considered a suitable candidate for newborn screening (NBS). Areas covered Many countries have introduced SCID screening based on T-cell receptor excision circle (TREC) detection in their NBS programs. Screening an entire population is a radical departure from previous paradigms in the field of immunology. Efficient screening strategies are cost-efficient and balance high sensitivity while preventing high numbers of referrals. NBS for SCID is accompanied by (actionable) secondary findings, but many NBS programs have optimized their screening strategy by adjusting algorithms or including second-tier tests. Harmonization of screening terminology is of great importance for international shared learning. Expert Opinion The expansion of NBS is driven by the development of new test modalities and treatment options. In the near future, other techniques such as next-generation sequencing will pave the way for NBS of other IEI. Exciting times await for population-based screening programs.
Sperm of more colourful males are better adapted to ovarian fluids in lake char (Salmonidae)

Fish often spawn eggs with ovarian fluids that have been hypothesized to support the sperm of some males over others (cryptic female choice). Alternatively, sperm reactions to ovarian fluids could reveal male strategies. We used wild‐caught lake char (Salvelinus umbla) to experimentally test whether sperm react differently to the presence of ovarian fluid, and whether any differential sperm reaction could be predicted by male breeding coloration, male inbreeding coefficients (based of 4150 SNPs) or the kinship coefficients between males and females. Male coloration was positively linked to body size and current health (based on lymphocytosis and thrombocytosis) but was a poor predictor of inbreeding or kinship coefficients. We found that sperm of more colourful males were faster in diluted ovarian fluids than in water only, while sperm of paler males were faster in water than in ovarian fluids. We then let equal numbers of sperm compete for fertilizations in the presence or absence of ovarian fluids and genetically assigned 1464 embryos (from 70 experimental trials) to their fathers. The presence of ovarian fluids significantly increased the success of the more colourful competitors. Sperm of less inbred competitors were more successful when tested in water only than in diluted ovarian fluids. The kinship coefficients had no significant effects on sperm traits or fertilization success in the presence of ovarian fluids, although parallel stress tests on embryos had revealed that females would profit more from mating with least related males rather than most coloured ones. We conclude that sperm of more colourful males are best adapted to ovarian fluids, and that the observed reaction norms suggest male strategies rather than cryptic female choice.
Achiral, Helicity Preserving, and Resonant Structures for Enhanced Sensing of Chiral Molecules

We derive a set of design requirements that lead to structures suitable for molecular circular dichroism (CD) enhancement. Achirality of the structure and two suitably selected sequentially incident beams of opposite helicity ensures that the CD signal only depends on the chiral absorption properties of the molecules, and not on the achiral ones. Under this condition, a helicity preserving structure, which prevents the coupling of the two polarization handednesses, maximizes the enhancement of the CD signal for a given ability of the structure to enhance the field. When the achirality and helicity preservation requirements are met, the enhancement of the CD signal is directly related to the enhancement of the field. Next, we design an exemplary structure following the requirements. The considered system is a planar array of silicon cylinders under normally incident plane-wave illumination. Full-wave numerical calculations show that the enhancement of the transmission CD signal is between 6.5 and 3.75 for .
Relation between athletic club affiliation from school age and future serum free testosterone levels in Japan: A cross‐sectional study

Testosterone deficiency is often related to geriatric syndrome including erectile dysfunction, osteo‐porosis, depression, cognitive impairment, cardiovascular diseases and frailty. Despite the existence of many studies on short‐term exercise and serum testosterone levels, few research have focused on exercise habits from young age and testosterone values in middle‐aged male. In this study, we investigated whether belonging to an athletic club from school age could predict serum‐free testosterone (FT) levels.
The Aging Ovary and the Tales Learned Since Fetal Development

Background: While the term “aging” implies a process typically associated with later life, the consequences of ovarian aging are evident by the time a woman reaches her forties, and sometimes earlier. This is due to a gradual decline in the quantity and quality of oocytes which occurs over a woman’s reproductive lifespan. Indeed, the reproductive potential of the ovary is established even before birth, as the proper formation and assembly of the ovarian germ cell population during fetal life determines the lifetime endowment of oocytes and follicles. In the ovary, sophisticated molecular processes have been identified that regulate the timing of ovarian aging and these are critical to ensuring follicular maintenance. Summary: The mechanisms thought to contribute to overall aging have been summarized under the term the “hallmarks of aging” and include such processes as DNA damage, mitochondrial dysfunction, telomere attrition, genomic instability, and stem cell exhaustion, among others. Similarly, in the ovary, molecular processes have been identified that regulate the timing of ovarian aging and these are critical to ensuring follicular maintenance. In this review, we outline critical processes involved in ovarian aging, highlight major achievements for treatment of ovarian aging, and discuss ongoing questions and areas of debate. Key Messages: Ovarian aging is recognized as what may be a complex process in which age, genetics, environment, and many other factors contribute to the size and depletion of the follicle pool. The putative hallmarks of reproductive aging outlined herein include a diversity of plausible processes contributing to the depletion of the ovarian reserve. More research is needed to clarify if and to what extent these putative regulators do in fact govern follicle and oocyte behavior, and how these signals might be integrated in order to control the overall pattern of ovarian aging.
