Authors: Zhang Xiaojin , Luo Qin , Huang Zhicheng , Xiang Xin 
Published: August 2023

Abstract
Introduction
Hearing loss is a prevalent health concern, and dietary factors, such as fatty acid intake, may play a role in its development. The current study aimed to investigate the association between the intake of dietary fatty acids and hearing thresholds among U.S. adults.

Methods
The researchers examined data from the National Health and Nutrition Examination Survey (NHANES), including 7,623 participants with available dietary fatty acid intake and audiometry data. Dietary fatty acid intake was assessed using dietary recalls, and hearing thresholds were measured using pure-tone audiometry. Multivariate linear regression models and smoothing curve fitting were utilized to explore the associations between dietary fatty acid intake and hearing thresholds, adjusting for relevant covariates.

Results
This study reveals a direct association between both low and high frequency pure tone average (PTA) hearing thresholds and the dietary intake of total saturated fatty acids (SFAs) and total polyunsaturated fatty acids (PUFAs). Conversely, the intake of total monounsaturated fatty acids (MUFAs) demonstrates an inverted U-shaped correlation with low-frequency and high-frequency PTA hearing thresholds, having inflection points at 11.91 (energy (%)) and 10.88 (energy (%)), respectively.

Conclusion
Dietary intake of certain fatty acids may influence hearing thresholds in adults.

Abstract
Background
Emerging ferroptosis-driven therapies based on nanotechnology function either by increasing intracellular iron level or suppressing glutathione peroxidase 4 (GPX4) activity. Nevertheless, the therapeutic strategy of simultaneous iron delivery and GPX4 inhibition remains challenging and has significant scope for improvement. Moreover, current nanomedicine studies mainly use disulfide-thiol exchange to deplete glutathione (GSH) for GPX4 inactivation, which is unsatisfactory because of the compensatory effect of continuous GSH synthesis.

Methods
In this study, we design a two-in-one ferroptosis-inducing nanoplatform using iron-based metal-organic framework (MOF) that combines iron supply and GPX4 deactivation by loading the small molecule buthionine sulfoxide amine (BSO) to block de novo GSH biosynthesis, which can achieve sustainable GSH elimination and dual ferroptosis amplification. A coated lipid bilayer (L) can increase the stability of the nanoparticles and a modified tumor-homing peptide comprising arginine-glycine-aspartic acid (RGD/R) can achieve tumor-specific therapies. Moreover, as a decrease in GSH can alleviate resistance of cancer cells to chemotherapy drugs, oxaliplatin (OXA) was also loaded to obtain BSO&OXA@MOF-LR for enhanced cancer chemo-ferrotherapy in vivo.

Results
BSO&OXA@MOF-LR shows a robust tumor suppression effect and significantly improved the survival rate in 4T1 tumor xenograft mice, indicating a combined effect of dual amplified ferroptosis and GSH elimination sensitized apoptosis.

Conclusion
BSO&OXA@MOF-LR is proven to be an efficient ferroptosis/apoptosis hybrid anti-cancer agent. This study is of great significance for the clinical development of novel drugs based on ferroptosis and apoptosis for enhanced cancer chemo-ferrotherapy.

Published: August 2023

AbstractZIF-8 may experience ion-responsive degradation in ionic solutions, which will change its initial architecture and restrict its direct biological use. Herein, we report an abnormal phenomenon in which ZIF-8 induces large hydroxyapatite-like crystals when soaked directly in simulated body fluid. These crystals grew rapidly continuously for two weeks, with the volume increasing by over 10 folds. According to Zn2+ release and novel XRD diffraction peak presence, ZIF-8 particles can probably show gradual collapse and became congregate through re-nucleation and competitive coordination. The phenomenon could be found on ZIF-8/PCL composite surface and printed ZIF-8/PCL scaffold surface. ZIF-8 enhanced PCL roughness through changing the surface topography, while obviously improving the in-vivo and in-vitro osteoinductivity and biocompatibility. The pro-biomineralization property can make ZIF-8 also applicable in polylactic acid-based biomaterials. In summary, this study demonstrates that ZIF-8 may play the role of a bioactive additive enabling the surface modification of synthetic polymers, indicating that it can be applied in in-situ bone regeneration.

Published: August 2023

AbstractBacterial infections can significantly impede wound healing and pose a serious threat to the patient’s life. The excessive use of antibiotics to combat bacterial infections has led to the emergence of multi-drug-resistant bacteria. Therefore, there is a pressing need for alternative approaches, such as photothermal therapy (PTT), to address this issue. In this study, for the first time, CuS NPs with photothermal properties were synthesized using sericin as a biological template, named CuS@Ser NPs. This method is simple, green, and does not produce toxic and harmful by-products. These nanoparticles were incorporated into a mixture (XK) of xanthan gum and konjac glucomannan (KGM) to obtain XK/CuS NPs composite hydrogel, which could overcome the limitations of current wound dressings. The composite hydrogel exhibited excellent mechanical flexibility, photothermal response, and biocompatibility. It also demonstrated potent antibacterial properties against both Gram-positive and negative bacteria via antibacterial experiments and accelerated wound healing in animal models. Additionally, it is proved that the hydrogel promoted tissue regeneration by stimulating collagen deposition, angiogenesis, and reducing inflammation. In summary, the XK/CuS NPs composite hydrogel presents a promising alternative for the clinical management of infected wounds, offering a new approach to promote infected wound healing.

Abstract
Background
Vitiligo is reported to affect 2% of the world’s population and has a significant impact on health related quality of life (HRQoL). The relationship between HRQoL and clinical outcomes used in vitiligo require further examination. Mapping condition specific measures of HRQoL: vitiligo specific quality of life instrument (VitiQoL), vitiligo noticeability scale (VNS) and vitiligo re-pigmentation scores (RPS) to the EQ-5D have not yet been reported.

Methods
Data collected from a randomised clinical trial (HI-Light) in vitiligo was used to develop mapping algorithms for the EQ-5D-5 L and the relationship between HRQoL, clinical outcomes and EQ-5D were investigated. Two EQ-5D-5 L value sets (Van Hout and Alava) using linear and non-linear models were considered. Logistic regression models were used to model the probability of vitiligo noticeability (VNS) in terms of RPS, EQ-5D and VitiQoL scores.

Results
Mapping from RPS appeared to perform better followed by VNS for the Alava crosswalks using polynomial models: Mean observed vs. predicted utilities of 0.9008 (0.005) vs. 0.8984 (0.0004) were observed for RPS. For VNS, mean observed vs. predicted utilities of 0.9008 (0.005) vs. 0.8939 (0.0003) were observed. For VitiQoL, mean observed vs. predicted utilities of 0.9008 (0.005) vs. 0.8912 (0.0002) were observed. For patients with the least re-pigmentation (RPS < 25%), a Total VitiQoL score of about 20 points gives around an 18% chance of vitiligo being no longer or a lot less noticeable.

Conclusion
The algorithm based on RPS followed by VNS performed best. The relationship between effects from vitiligo specific HRQoL instruments and clinical RPS was established allowing for plausible clinically relevant differences to be identified, although further work is required in this area.

Authors: Myhrvold Birgitte Lawaetz , Vikhaug Tora Bjørkmann , DuRose Alister , Gausel Anne Marie , Eklund Andreas , Axén Iben 
Published: August 2023

Abstract
Background
Chiropractors use a treatment strategy called maintenance care with the intent of secondary and tertiary prevention. The Nordic Maintenance Care Program provides evidence of when and for whom maintenance care should be offered. Dissemination has occurred through articles, workshops, social media, conference in Europe and internationally. However, little is known about chiropractors’ awareness and use of this evidence. This study explores chiropractors’ attitudes, skills, and use of evidence on maintenance care, as well as study their association with general evidence-based practice and demographic characteristics. Moreover, barriers and facilitators of evidence access are also examined.

Methods
Questions pertaining our research aim were included in the anonymous and digital Evidence-Based practice Attitude and utilization SurvEy, which was distributed to all members (n = 770) of the Norwegian chiropractic association in the fall of 2021.

Results
The response rate was 41% (n = 312). Regarding attitudes towards evidence-based maintenance care, 26% agreed they needed tools to recommend this care to patients. Approximately half (57%) believed they had skills to identify suitable patients, and 45% had used published information in the past month. Strong alignment was observed between Norwegian chiropractors’ attitudes, skills, and utilization of evidence-based maintenance care and general evidence-based practice. Maintenance care skills were significantly associated with age (those between 40 and 59 years being less likely to report having high skills), clinical setting (those working with conventional health care providers being less likely to report having high skills) and country of education (those educated in the US and Australia being more likely to report having high skills). Moreover, maintenance care use was significantly associated with country of education (those educated in Australia were less likely to have used published information regarding patient selection for maintenance care). Access to resources was a barrier, whereas knowledge of patient suitability facilitated evidence-based maintenance care.

Conclusions
Norwegian chiropractors had neutral attitudes towards maintenance care, but generally reported moderate skills. Most had not used evidence about maintenance care in the previous month. Access to useful resources about the evidence regarding maintenance care was a barrier, and knowledge of who responds to maintenance care was a facilitator.

Published: August 2023

Abstract
Background
Many women have low confidence in breastfeeding and have concerns regarding low milk volume or discomfort with breastfeeding. Antenatal hand expression may be an opportunity to help women feel more comfortable with breastfeeding and help promote exclusive breastfeeding. A study at a hospital in Philadelphia, Pennsylvania, U.S. assessed the feasibility of teaching antenatal hand expression at 39 weeks among socioeconomically disadvantaged populations, overall participant satisfaction and adoption of hand expression and breastfeeding.

Methods
From March 2020 to June 2021, women recruited at 34–39 weeks were taught to hand express, collect, and store colostrum. Starting from 39 weeks, participants were asked to practice hand expression 1–3 times / day until delivery, log their experiences, and store colostrum expressed. Women were contacted to encourage continued hand expression and answer any questions. Postpartum, a survey assessed satisfaction with hand expression and issues encountered. The survey also inquired about breastfeeding plans and barriers, and whether women were exclusively breastfeeding (defined as infants who received only breastmilk from the time of birth). Chart review of postpartum or well-baby visit notes determined whether women continued breastfeeding.

Results
Of the 29 participants, 72% (21/29) reported hand expressing at home, and no women reported contractions when hand expressing. Participants rated mean satisfaction of 8.1/10 (SD = 1.62) with antenatal hand expression, mean satisfaction of 9.4/10 (SD = 0.90) toward hand expression education, mean likelihood of 9.4/10 (SD = 1.24) recommending hand expression to others, and a mean score of 8.1/10 (SD = 1.69) on how helpful hand expression was in breastfeeding initiation. 90% (26/29) of women initiated breastfeeding after birth and 72% (21/29) exclusively breastfed on discharge, but only 11/29 (38%) continued exclusively breastfeeding when re-assessed 4–6 weeks postpartum. Barriers included maternal discomfort, low milk supply, and maternal or infant illness.

Conclusions
This study suggests that women in an urban setting would be willing to practice antenatal hand expression. A larger and adequately powered study could be feasible to determine associations between antenatal hand expression and breastfeeding rates and confidence.

Authors: Du Jianqiang , Qin Wenxiu , Zhang Yanjun , Yang Zhengyuan , Li Junjie , Yang Jun , Deng Qiang 
Published: August 2023

Abstract
Purpose
In spinal tuberculosis surgery, topical administration of drugs to the lesion is a preventive treatment measure. The aim is to achieve better bacterial inhibition and to prevent complications. As one of the most common complications after spinal tuberculosis surgery, many factors can lead to surgical site infection (SSI). No definitive reports of local streptomycin irrigation of the lesion and SSI of spinal tuberculosis have been seen. This study analyzed data related to surgical site infections (SSI) after the treatment of spinal tuberculosis using this regimen.

Methods
In this study, 31 were in the observation group (streptomycin flush) and 34 in the control group (no streptomycin flush). All patients received the same standard of perioperative care procedures. General information, operative time, intraoperative bleeding, ESR and CRP at one week postoperatively, time on antibiotics, total drainage, days in hospital, incision infection rate and secondary debridement rate were compared between the two groups.

Results
Patients in both groups completed the surgery successfully. The ESR and CRP levels in the observation group were lower than those in the control group one week after surgery (p < 0.05); the duration of postoperative antibiotics and hospital stay were lower than those in the control group (p < 0.05); the incidence of SSI in the two groups was 5.88% and 6.45% respectively, with no significant difference (p > 0.05).

Conclusion
The use of topical streptomycin irrigation of the lesion during surgical procedures for spinal tuberculosis had no significant effect on the incidence of SSI, however, it helped to control the level of infection in the postoperative period and reduced the length of time patients had to use postoperative antibiotics and the number of days they stayed in hospital. Future prospective randomised controlled trials in more centres and larger samples are recommended.
Linkage and association of variants in the dopamine receptor 2 gene (DRD2) with polycystic ovary syndrome
Authors: Amin Mutaz , Horst Nicholas , Gragnoli Claudia 
Published: August 2023

AbstractPolycystic ovarian syndrome (PCOS) is a disorder with a foundation of neuroendocrine dysfunction, characterized by increased gonadotropin-releasing hormone (GnRH) pulsatility, which is antagonized by dopamine. The dopamine receptor 2 (DRD2), encoded by theDRD2gene, has been shown to mediate dopamine’s inhibition of GnRH neuron excitability through pre- and post-synaptic interactions in murine models. Further, DRD2 is known to mediate prolactin (PRL) inhibition by dopamine, and high blood level of PRL have been found in more than one third of women with PCOS. We recently identifiedPRLas a gene contributing to PCOS risk and reportedDRD2conferring risk for type 2 diabetes and depression, which can both coexist with PCOS. Given DRD2 mediating dopamine’s action on neuroendocrine profiles and association with metabolic-mental states related to PCOS, polymorphisms inDRD2may predispose to development of PCOS. Therefore, we aimed to investigate whetherDRD2variants are in linkage to and/or linkage disequilibrium (i.e., linkage and association) with PCOS in Italian families. In 212 Italian families, we tested 22 variants within theDRD2gene for linkage and linkage disequilibrium with PCOS. We identified five novel variants significantly linked to the risk of PCOS. This is the first study to identifyDRD2as a risk gene in PCOS, however, functional studies are needed to confirm these results.
Maast: genotyping thousands of microbial strains efficiently
Authors: Shi Zhou Jason , Nayfach Stephen , Pollard Katherine S. 
Published: August 2023

AbstractExisting single nucleotide polymorphism (SNP) genotyping algorithms do not scale for species with thousands of sequenced strains, nor do they account for conspecific redundancy. Here we present a bioinformatics tool, Maast, which empowers population genetic meta-analysis of microbes at an unrivaled scale. Maast implements a novel algorithm to heuristically identify a minimal set of diverse conspecific genomes, then constructs a reliable SNP panel for each species, and enables rapid and accurate genotyping using a hybrid of whole-genome alignment and k-mer exact matching. We demonstrate Maast’s utility by genotyping thousands of Helicobacter pylori strains and tracking SARS-CoV-2 diversification.

Abstract
Introduction
Type 2 diabetes mellitus (T2DM) is a non-communicable disease representing one of the most serious public health challenges of the twenty-first century. Its incidence continues to rise in both developed and developing countries, causing the death of 1.5 million people every year. The use of technology (e.g. smartphone application—App) in the health field has progressively increased as it has been proved to be effective in helping individuals manage their long-term diseases. Therefore, it has the potential to reduce the use of health service and its related costs. The objective of this study is to evaluate the impact of using a digital platform called “TreC Diabete” embedded into a novel organisational asset targeting poorly controlled T2DM individuals in the Autonomous Province of Trento (PAT), Italy.

Methods
This trial was designed as a multi-centre, open-label, randomised, superiority study with two parallel groups and a 1:1 allocation ratio. Individuals regularly attending outpatient diabetes clinics, providing informed consent, are randomised to be prescribed TreC Diabete platform as part of their personalised care plan. Healthcare staff members will remotely assess the data shared by the participants through the App by using a dedicated online medical dashboard. The primary end-point is the evaluation of the Hb1Ac level at 12-month post-randomisation. Data will be analysed on an intention-to-treat (ITT) basis.

Discussion
This trial is the first conducted in the PAT area for the use of an App specifically designed for individuals with poorly controlled T2DM. If the effects of introducing this specific App within a new organisational asset are positive, the digital platform will represent a possible way for people diagnosed with T2DM to better manage their health in the future. Results will be disseminated through conferences and peer-reviewed journals once the study is completed.
