Authors: Goel Muskan , Mackeyev Yuri , Krishnan Sunil 
Published: February 2023

AbstractIn the last three decades, radiopharmaceuticals have proven their effectiveness for cancer diagnosis and therapy. In parallel, the advances in nanotechnology have fueled a plethora of applications in biology and medicine. A convergence of these disciplines has emerged more recently with the advent of nanotechnology-aided radiopharmaceuticals. Capitalizing on the unique physical and functional properties of nanoparticles, radiolabeled nanomaterials or nano-radiopharmaceuticals have the potential to enhance imaging and therapy of human diseases. This article provides an overview of various radionuclides used in diagnostic, therapeutic, and theranostic applications, radionuclide production through different techniques, conventional radionuclide delivery systems, and advancements in the delivery systems for nanomaterials. The review also provides insights into fundamental concepts necessary to improve currently available radionuclide agents and formulate new nano-radiopharmaceuticals.

Published: February 2023

AbstractThe use of flow cytometry to enumerate microorganisms is gaining traction over the traditional plate count technique on the basis of superior accuracy, precision and time-to-result. Here, we assessed the suitability of live/dead flow cytometry for the enumeration of mixed populations of probiotic bacteria (L. acidophilus, L. paracasei, L. plantarum, L. salivarius, B. lactis and B. bifidum) whilst comparing outcomes with plate counting. Using a novel gating strategy designed specifically for the enumeration of mixed populations, the application of flow cytometry resulted in the detection of higher numbers of viable bacteria with a greater level of repeatability than plate counting (RSD of 6.82 and 13.14% respectively). Across all multi-species blends tested, viable cell input was more accurately recovered by flow cytometry (101.8 ± 6.95%) than plate counts (81.37 ± 16.03%). However, when certain probiotic mixtures contained preparations with high numbers of non-viable cells in their total population, flow cytometry had the potential for overestimation of the viable population. Nevertheless, the comparative plate counts of these mixtures were low and variable, thus supporting the use of flow cytometry for the enumeration of viable bacteria in mixed populations.

Abstract
Background
The emergence of carbapenem-resistant Enterobacterales (CRE) continues to threaten public health due to limited therapeutic options. In the current study the incidence of carbapenem resistance among the 104 clinical isolates of Escherichia coli and the genomic features of carbapenem resistant isolates were investigated.

Methods
The susceptibility to imipenem, tigecycline and colistin was tested by broth dilution method. Susceptibility to other classes of antimicrobials was examined by disk diffusion test. The presence of blaOXA-48, blaKPC, blaNDM, and blaVIM carbapenemase genes was examined by PCR. Molecular characteristics of carbapenem resistant isolates were further investigated by whole-genome sequencing (WGS) using Illumina and Nanopore platforms.

Results
Four isolates (3.8%) revealed imipenem MIC of ≥32 mg/L and positive results for modified carbapenem inactivation method and categorized as carbapenem resistant E. coli (CREC). Colistin, nitrofurantoin, fosfomycin, and tigecycline were the most active agents against all isolates (total susceptibility rate of 99, 99, 96 and 95.2% respectively) with the last three compounds being found as the most active antimicrobials for carbapenem resistant isolates (susceptibility rate of 100%). According to Multilocus Sequence Type (MLST) analysis the 4 CREC isolates belonged to ST167 (n = 2), ST361 (n = 1) and ST648 (n = 1). NDM was detected in all CREC isolates (NDM-1 (n = 1) and NMD-5 (n = 3)) among which one isolate co-harbored NDM-5 and OXA-181 carbapenemases. WGS further detected blaCTX-M-15, blaCMY-145, blaCMY-42 and blaTEM-1 (with different frequencies) among CREC isolates. Co-occurrence of NDM-type carbapenemase and 16S rRNA methyltransferase RmtB and RmtC was found in two isolates belonging to ST167 and ST648. A colistin-carbapenem resistant isolate which was mcr-negative, revealed various amino acid substitutions in PmrB, PmrD and PhoPQ proteins.

Conclusion
About 1.9% of E. coli isolates studied here were resistant to imipenem, colistin and/or amikacin which raises the concern about the outbreaks of difficult-to-treat infection by these emerging superbugs in the future.

Published: February 2023

Abstract
Background
Sensoready® autoinjector pen facilitates self-administration of subcutaneous ofatumumab injections at home. We aim to investigate patient and nurse preference for using Sensoready® versus comparator autoinjectors in multiple sclerosis (MS).

Methods
A pilot survey was conducted in Germany followed by in-field interviews across United States, Germany, France, and Italy. The survey recruited 80 MS patients and 50 MS nurses. Respondents were interviewed for 45-min on qualitative open-ended and quantitative close-ended survey consisting of 31 questions for patients and 41 for nurses. Ratings were measured on Likert scale from 1 (not at all important) to 10 (extremely important).

Results
“Easy to perform self-injection with the pen” and “Patient able to use independently” (both, mean overall score 9.4) were the most important attributes for both patients and nurses. Sensoready® scored high across most important attributes for both patients and nurses (p < 0.05). Sensoready® was preferred over comparator devices across majority of the important attributes (84%; p < 0.05), especially ease of use of the pen (mean overall score 9.4). Sensoready® was preferred over their current device by 9/10 nurses and 8/10 patients if they had to choose a treatment based on the device alone.

Conclusion
Both MS patients and nurses preferred the Sensoready® (ofatumumab) over comparator autoinjectors for their treatment, mostly driven by ease of administration.
A randomised clinical trial comparing outcomes of a single digit volar plate injury — Buddy loops versus dorsal thermoplastic orthosis in a neutral position: study protocol
Authors: Walsh Sarah , Fahey Paul , Liu Karen 
Published: February 2023

AbstractBackgroundVolar plate injuries are a common hand injury and complications associated with this injury such as a fixed flexion deformity, persistent pain and oedema can have a significant impact on a person’s function. The literature reports these injuries are treated using various splinting materials such as thermoplastic, in varying degrees of proximal interphalangeal joint flexion or buddy loops. Despite volar plate injuries being reported as common, optimal non-surgical treatment of these injuries remains unclear.This study aims to investigate whether a dorsal blocking orthosis in a neutral position (00) is more effective than buddy loops for a volar plate injury to the proximal interphalangeal joint in preventing a fixed flexion deformity, reducing pain, managing oedema, and promoting function.MethodsThis study is a single-centre, prospective parallel-group, single blinded (assessor), randomised clinical trial. Patients between 18–65 years, who have sustained a volar plate injury to a single digit, have adequate cognitive functioning and give written informed consent will be invited to participate in this study. Patients will be randomised to either the control group where they will be fitted with buddy loops and commence early active motion exercises or the experimental group where they will receive a dorsal thermoplastic orthosis in a neutral position and commence early active motion exercises. The primary outcome measure is passive proximal interphalangeal joint extension and secondary outcome measures include passive range of motion, total passive motion, active range of motion, total active motion, grip strength, oedema, pain, function and adherence to treatment. Assessments will be completed until 8 weeks following commencement of treatment. The sample size calculation indicates that 23 patients is required in each group. With an expected dropout rate of 25% a total of 32 patients will be enrolled in each group.DiscussionThis study will assist in trying to improve treatment of volar plate injuries and assist in reducing complications associated with volar plate injuries, potentially reducing the need for prolonged hand therapy.Trial registrationThis trial has been registered with the Australian New Zealand Clinical Trials Registry (ACTRN12622001425785p). Ethical approval has been granted by the South Eastern Sydney Local Health District ethical committee (2022/ETH01697).
Hot fomentation of newborn fontanelles as an indigenous practice in Ghana: implications for policy and integrated community-based health care in Covid-19 pandemic and beyond

Published: February 2023

Abstract
Objective
African newborns undergo numerous traditional and religious practices ranging from fontanelle fomentation to total head shaving, scalp molding, skin scarification and ano-genital irrigation which can negatively impact the health of neonates. Hot fomentation of fontanelles has been a predominant indigenous home-based postnatal practice in Ghana and among Africans in the diaspora. Mobility restrictions during the Covid-19 pandemic has impacted direct access to facility-based care as well as home care. The flourishing of newborn traditional practices among African populations during this Covid-19 pandemic offers opportunities to rethink the provision of family healthcare support for newborns during the ongoing pandemic and beyond. Hence, the aim of this critical review was to examine and describe a common indigenous practice—hot fontanelle fomentation to inform home birth support, discharge planning, and the delivery of optimal home-based care support.

Study design
This study is a review of literature on hot fomentation of newborn fontanelles.

Methods
Literature search in CINAHL, PubMed, African Index Medicus and Scopus, was conducted and evidence synthesised from articles ranging from 1983–2022. Sixty articles were reviewed; however, 10 manuscripts were excluded prior to screening. The other 19 were exempted because they were either below 1983 or were not the best fit for the study purpose. In all, 31 studies were included in the study. The study was guided by Madeleine Leininger’s Culture Care Diversity and Universality care theory.

Results
The current study identifies hot fomentation of newborn fontanelles practices in Ghana, the description of hot fomentation practices and the dangers associated with it. The findings and suggested ways to help overcome this challenge.

Conclusion
There are several neonatal indigenous practices including fontanelle fomentation which pose threat to the health of the neonate as discussed in this study. Future research needs to investigate innovative ways of fontanelle fomentation where necessary instead of the use of hot water by mothers, especially in this Covid-19 pandemic where health and mobility restrictions impact physical access to timely health care. This research will help educate mothers about the dangers of fontanel fomentation and reduce the practice, especially in rural areas of developing countries. This could help reduce neonatal mortality and unnecessary healthcare costs.

Abstract
Background
Chlordecone is a highly persistent organochlorine insecticide that was intensively used in banana fields in the French West Indies, resulting in a widespread contamination. Neurotoxicity of acute exposures in adults is well recognized, and empirical data suggests that prenatal exposure affects visual and fine motor developments during infancy and childhood, with greater susceptibility in boys.

Objective
To assess the associations between pre- and postnatal exposures to chlordecone and cognitive and behavioral functions in school-aged children from Guadeloupe.

Methods
We examined 576 children from the TIMOUN mother–child cohort in Guadeloupe at 7 years of age. Concentrations of chlordecone and other environmental contaminants were measured in cord- and children’s blood at age 7 years. Cognitive abilities of children were assessed with the Wechsler Intelligence Scale for Children-IV (WISC-IV), and externalizing and internalizing problem behaviors documented with the Strengths and Difficulties Questionnaire (SDQ) completed by the child’s mother. We estimated covariate-adjusted associations between cord- and 7-years chlordecone concentrations and child outcomes using structural equations modeling, and tested effect modification by sex.

Results
Geometric means of blood chlordecone concentrations were 0.13 µg/L in cord blood and 0.06 µg/L in children’s blood at age 7 years. A twofold increase in cord blood concentrations was associated with 0.05 standard deviation (SD) (95% Confidence Interval [CI]: 0.0, 0.10) higher internalizing problem scores, whereas 7-years chlordecone concentrations were associated with lower Full-Scale IQ scores (FSIQ) and greater externalized behavioral problem scores. A twofold increase in 7-year chlordecone concentrations was associated with a decrease of 0.67 point (95% CI: -1.13, -0.22) on FSIQ and an increase of 0.04 SD (95% CI: 0.0, 0.07) on externalizing problems. These associations with Cognitive abilities were driven by decreases in perceptive reasoning, working memory and verbal comprehension. Associations between 7-year exposure and perceptive reasoning, working memory, and the FSIQ were stronger in boys, whereas cord blood and child blood associations with internalizing problems were stronger in girls.

Conclusions
These results suggests that cognitive abilities and externalizing behavior problems at school age are impaired by childhood, but not in utero, exposure to chlordecone, and that prenatal exposure is related to greater internalizing behavioral problems.
The impact of depression at preconception on pregnancy planning and unmet need for contraception in the first postpartum year: a cohort study from rural Malawi

Published: February 2023

Abstract
Background
The impact of depression on women’s use of contraception and degree of pregnancy planning in low-income settings has been poorly researched. Our study aims to explore if symptoms of depression at preconception are associated with unplanned pregnancy and nonuse of contraception at the point of conception and in the postpartum period.

Methods
Population-based cohort of 4244 pregnant women in rural Malawi were recruited in 2013 and were followed up at 28 days, 6 months and 12 months postpartum. Women were asked about symptoms of depression in the year before pregnancy and assessed for depression symptoms at antenatal interview using the Self‐Reporting Questionnaire‐20, degree of pregnancy planning using the London Measure of Unplanned Pregnancy and use of contraception at conception and the three time points postpartum.

Results
Of the 3986 women who completed the antenatal interview, 553 (13.9%) reported depressive symptoms in the year before pregnancy and 907 (22.8%) showed current high depression symptoms. History of depression in the year before pregnancy was associated with inconsistent use of contraception at the time of conception [adjusted relative risk (adjRR) 1.52; 95% confidence interval (1.24–1.86)] and higher risk of unplanned [adjRR 2.18 (1.73–2.76)] or ambivalent [adj RR 1.75 (1.36–2.26)] pregnancy. At 28 days post-partum it was also associated with no use of contraception despite no desire for a further pregnancy [adjRR 1.49 (1.13–1.97)] as well as reduced use of modern contraceptives [adj RR 0.74 (0.58–0.96)]. These results remained significant after adjusting for socio-demographic factors known to impact on women’s access and use of family planning services, high depression symptoms at antenatal interview as well as disclosure of interpersonal violence. Although directions and magnitudes of effect were similar at six and 12 months, these relationships were not statistically significant.

Conclusions
Depression in the year before pregnancy impacts on women’s use of contraception at conception and in the early postpartum period. This places these women at risk of unplanned pregnancies in this high fertility, high unmet need for contraception cohort of women in rural Malawi. Our results call for higher integration of mental health care into family planning services and for a focus on early postnatal contraception.
Bimanual movements in children with cerebral palsy: a systematic review of instrumented assessments
Authors: Cacioppo Marine , Loos Anthéa , Lempereur Mathieu , Brochard Sylvain 
Published: February 2023

AbstractBackgroundAssessment of bimanual movements, which are frequently impaired in children with cerebral palsy, is highly challenging in clinical practice. Instrumented measures have been developed to evaluate and help to understand impaired upper limb movement during bimanual tasks in these children. The aim of this review was to report instrumented measurement tools (3D motion analysis, sensors, etc.) used for bimanual task movement analysis, and the metrological properties of the measures in children with cerebral palsy.MethodsA systematic review was conducted (Prospero CRD42022308517). PubMed, Web of Science, Cochrane and Scopus databases were searched with relevant keywords and inclusion/exclusion criteria. Article quality and biomechanical methods were evaluated with a customized scale and metrological properties with the COSMIN checklist.ResultsIn total, 452 children, mostly with unilateral cerebral palsy, mean age 10.9 (SD 3.2) years, underwent quantitative bimanual assessments in the 31 included studies (mean quality score 22/32 points [SD 4.7]). The tools used were 3D motion analysis (n = 26), accelerometers (n = 2), and other instruments (cube, digitizer, etc.) (n = 3). Children performed 1–5 bimanual tasks in laboratory settings, mostly activities of daily living or game scenarios. Analyses focused mostly on spatiotemporal variables, 6 of which were specifically developed for bilateral measures (task completion time, goal synchronization, movement overlap time, interlimb coupling, continuous relative phase and asynchrony). These instrumented measurements had moderate to good discriminant and convergent validity, but reliability and responsiveness assessments were lacking.ConclusionsA large number of quantitative bimanual assessments involving different tools, bimanual tasks and specific variables developed to evaluate bimanual function were found. Development of other relevant variables and validation of these tools are needed to further determine their usefulness, both as research outcomes and to guide therapies in clinical practice. Future research, involving younger children and real-life assessments, will improve our understanding of bimanual function in children with cerebral palsy.

Abstract
Background
Esophageal squamous cell carcinoma (ESCC) is a common gastrointestinal malignancy with poor patient prognosis. Current treatment for ESCC, including immunotherapy, is only beneficial for a small subset of patients. Better characterization of the tumor microenvironment (TME) and the development of novel therapeutic targets are urgently needed.

Methods
In the present study, we hypothesized that integration of single-cell transcriptomic sequencing and large microarray sequencing of ESCC biopsies would reveal the key cell subtypes and therapeutic targets that determine the prognostic and tumorigenesis of ESCC. We characterized the gene expression profiles, gene sets enrichment, and the TME landscape of a microarray cohort including 84 ESCC tumors and their paired peritumor samples. We integrated single-cell transcriptomic sequencing and bulk microarray sequencing of ESCC to reveal key cell subtypes and druggable targets that determine the prognostic and tumorigenesis of ESCC. We then designed and screened a blocking peptide targeting Chemokine C–C motif ligand 18 (CCL18) derived from tumor associated macrophages and validated its potency by MTT assay. The antitumor activity of CCL18 blocking peptide was validated in vivo by using 4-nitroquinoline-1-oxide (4-NQO) induced spontaneous ESCC mouse model.

Results
Comparative gene expression and cell–cell interaction analyses revealed dysregulated chemokine and cytokine pathways during ESCC carcinogenesis. TME deconvolution and cell interaction analyses allow us to identify the chemokine CCL18 secreted by tumor associated macrophages could promote tumor cell proliferation via JAK2/STAT3 signaling pathway and lead to poor prognosis of ESCC. The peptide Pep3 could inhibit the proliferation of EC-109 cells promoted by CCL18 and significantly restrain the tumor progression in 4-NQO-induced spontaneous ESCC mouse model.

Conclusions
For the first time, we discovered and validated that CCL18 blockade could significantly prevent ESCC progression. Our study revealed the comprehensive cell–cell interaction network in the TME of ESCC and provided novel therapeutic targets and strategies to ESCC treatment.
