Epicardial pacing lead implantation for congenital complete atrioventricular block immediately after birth: a case report
Authors: Amino Hiroaki , Kinoshita Mao , Shibasaki Masayuki 
Published: November 2023

Abstract
Background
The incidence of congenital complete atrioventricular block is estimated to be 1 per 20,000 deliveries. In the fetal period, the fetal mortality rate is high, but the treatment strategy has not yet been established. In severe cases, early postnatal pacing therapy is necessary.

Case presentation
A 0-day-old Japanese baby girl was diagnosed with fetal congenital complete atrioventricular block during a prenatal physical examination. A joint conference was held preoperatively among multidisciplinary departments, and a cesarean section was performed at 37 weeks pregnancy, immediately followed by scheduled internal ventricular pacing lead implantation in an adjacent room. Percutaneous pacing was ineffective. The epicardial pacing lead was sutured at 17.5 minutes after birth, and perioperative management was successful with a heart rate and pulse rate of 150 beats per minute.

Conclusion
The infant with a congenital complete atrioventricular block was rescued by an uneventful epicardial lead implantation.

AbstractBackgroundThe widespread nature of plastic pollution has given rise to wide scientific and social concern regarding the capacity of these materials to serve as vectors for pathogenic bacteria and reservoirs for Antimicrobial Resistance Genes (ARG).In-andex-situincubations were used to characterise the riverine plastisphere taxonomically and functionally in order to determine whether antibiotics within the water influenced the ARG profiles in these microbiomes and how these compared to those on natural surfaces such as wood and their planktonic counterparts.ResultsWe show that plastics support a taxonomically distinct microbiome containing potential pathogens and ARGs. While the plastisphere was similar to those biofilms that grew on wood, they were distinct from the surrounding water microbiome. Hence, whilst potential opportunistic pathogens (i.e.Pseudomonas aeruginosa,AcinetobacterandAeromonas) and ARG subtypes (i.e. those that confer resistance to macrolides/lincosamides, rifamycin, sulfonamides, disinfecting agents and glycopeptides) were predominant in all surface-related microbiomes, especially on weathered plastics, a completely different set of potential pathogens (i.e. Escherichia,Salmonella,KlebsiellaandStreptococcus) and ARGs (i.e. aminoglycosides, tetracycline, aminocoumarin, fluoroquinolones, nitroimidazole, oxazolidinone and fosfomycin) dominated in the planktonic compartment. Our genome-centric analysis allowed the assembly of 215 Metagenome Assembled Genomes (MAGs), linking ARGs and other virulence-related genes to their host. Interestingly, a MAG belonging toEscherichia–that clearly predominated in water– harboured more ARGs and virulence factors than any other MAG, emphasising the potential virulent nature of these pathogenic-related groups. Finally,ex-situincubations using environmentally-relevant concentrations of antibiotics increased the prevalence of their corresponding ARGs, but different riverine compartments –including plastispheres– were affected differently by each antibiotic.ConclusionsOur results provide insights into the capacity of the riverine plastisphere to harbour a distinct set of potentially pathogenic bacteria and function as a reservoir of ARGs. The environmental impact that plastics pose if they act as a reservoir for either pathogenic bacteria or ARGs is aggravated by the persistence of plastics in the environment due to their recalcitrance and buoyancy. Nevertheless, the high similarities with microbiomes growing on natural co-occurring materials and even more worrisome microbiome observed in the surrounding water highlights the urgent need to integrate the analysis of all environmental compartments when assessing risks and exposure to pathogens and ARGs in anthropogenically-impacted ecosystems.

Published: November 2023

Abstract
Background
Recent studies have indicated a strong correlation between endoplasmic reticulum (ER) stress and myopia and that eyedrops containing the ER stress inducer tunicamycin (Tm) can induce myopic changes in C57BL/6 J mice. Therefore, this study aimed to create a new myopia model using Tm eyedrops and to explore the mechanism of ER stress-mediated myopia development.

Methods
Three-week-old C57BL/6 J mice were treated with different concentrations (0, 25, 50, and 100 μg/mL) and/or number of applications (zero, one, three, and seven) of Tm eyedrops. Refraction and axial length (AL) were measured before and one week after Tm treatment. Scleral collagen alterations were evaluated under polarised light after picrosirius red staining. ER stress-related indicators, such as the expression of collagen I and cleaved collagen were detected using Western blotting.

Results
Compared with the control group, mice administered eyedrops with 50 μg/mL Tm only once showed the greatest myopic shifts in refraction and AL elongation and reduced scleral expression of collagen I. Picrosirius red staining showed a lower percentage of bundled collagen in the Tm group. Expression of ER-stress indicators increased in the Tm groups. Furthermore, optimised administration of Tm induced matrix metalloproteinase-2 (MMP2) expression in the sclera, which plays a major role in collagen degradation.

Conclusions
We have demonstrated that ER stress in the sclera is involved in myopia progression. Tm eyedrops induced myopic changes, loosening of the scleral collagen and decreased expression of collagen I. This process may be associated with ER stress in the sclera, which upregulates the expression of MMP2 leading to collagen degradation.
Traumatic dental injuries over an 8-year period at a German dental center: a retrospective overview and cross-sectional analysis
Authors: Parvini Puria , Lermen Yanislava , Sader Robert , Schwarz Frank , Obreja Karina 
Published: November 2023

Abstract
Background/aim
The aim of this study was to analyze a population of patients who had suffered from traumatic dental injuries (TDIs) by using different patient-, trauma- and treatment-related parameters.

Material and methods
All dental records of patients ≥ 3 years old who had presented at the dental emergency service between Jan 1, 2009 and Dec 31, 2016 for the treatment of dental trauma were analyzed. A total of 2758 patients were invited for a recall examination at the Department for Dental Surgery and Implantology, ZZMK Carolinum, Goethe University Frankfurt, Germany; of these, 269 patients attended their recall appointments.

Results
The enrolled patient population consisted of 1718 males and 1040 females, with a mean age of 19.63 years (median 12.00 ± 17.354 years). A total of 4909 injured teeth were assessed, with a mean of 1.78 injured teeth per patient (median 2.00 ± 1.279). Males were found to be more frequently affected by TDIs compared to females (1.65:1). The majority of these injuries occurred in the first two decades of life (66.1%; n = 1824). The majority of the patients presented for initial treatment within 24 h of their accident (95.7%). The most frequent TDIs were isolated luxation injuries 49.4% (n = 2426) and isolated crown fractures 30% (n = 1472). Combination injuries were diagnosed in 20.6% of the cases (n = 1011).

Conclusions
Based on the findings of the present analysis, it can be concluded that males were more frequently affected by TDIs than females. Most patients had suffered from TDI before they had turned 10 years of age. Overall, the enamel–dentin fracture was found to be the most frequent injury, followed by concussions and lateral luxations.

Abstract
Objective
Our objective was to analyze a prospective population-based registry including five sites in four low- and middle-income countries to observe characteristics associated with vaginal birth after cesarean versus repeat cesarean birth, as well as maternal and newborn outcomes associated with the mode of birth among women with a history of prior cesarean.

Hypothesis
Maternal and perinatal outcomes among vaginal birth after cesarean section will be similar to those among recurrent cesarean birth.

Methods
A prospective population-based study, including home and facility births among women enrolled from 2017 to 2020, was performed in communities in Guatemala, India (Belagavi and Nagpur), Pakistan, and Bangladesh. Women were enrolled during pregnancy, and delivery outcome data were collected within 42 days after birth.

Results
We analyzed 8267 women with a history of prior cesarean birth; 1389 (16.8%) experienced vaginal birth after cesarean, and 6878 (83.2%) delivered by a repeat cesarean birth. Having a repeat cesarean birth was negatively associated with a need for curettage (ARR 0.12 [0.06, 0.25]) but was positively associated with having a blood transfusion (ARR 3.74 [2.48, 5.63]). Having a repeat cesarean birth was negatively associated with stillbirth (ARR 0.24 [0.15, 0.49]) and, breast-feeding within an hour of birth (ARR 0.39 [0.30, 0.50]), but positively associated with use of antibiotics (ARR 1.51 [1.20, 1.91]).

Conclusions
In select South Asian and Latin American low- and middle-income sites, women with a history of prior cesarean birth were 5 times more likely to deliver by cesarean birth in the hospital setting. Those who delivered vaginally had less complicated pregnancy and labor courses compared to those who delivered by repeat cesarean birth, but they had an increased risk of stillbirth. More large scale studies are needed in Low Income Country settings to give stronger recommendations.

Faculty publication trends in a Japanese national university: a diachronic document analysis
Authors: Muller Theron , Takano Miho , Gallagher Nicole 
Published: November 2023

Abstract
Background
We previously demonstrated that in a Japanese national university’s medical faculty, overall paper publication frequency increased between 1979﻿–1980 and 2017–2018, while original paper publication did not increase. Further, publication language changed from predominantly Japanese to English. However, whether these trends are specific to medicine or representative of other faculties remains unclear.

Methods
We diachronically analyzed annual university library-produced publication reports for four pharmaceutical and three medical units between 1979﻿–1980 and 2019–2020, elucidating how publication frequency, type, and language medium changed.

Results
All publication types increased for the pharmaceutical faculty, from 2.87 per faculty member per year to 10.77. Publication of original papers more than doubled, from 1.06 per faculty member per year to 2.37. This increase was exclusively in English publication, with no publication of Japanese original papers in 2019–2020. This contrasts with medicine, which, while it demonstrated similar increases in all publication types combined, from 4.92 papers per faculty member per year to 12.78, did not demonstrate as striking an increase in total original paper publication (English and Japanese), from 1.21 papers per faculty member per year to 1.30. However, these two faculties observed similar trends in that English largely replaced Japanese original paper publication. That both faculties’ Japanese original paper publication decreased suggests English language original paper publication comes at the expense of publishing in Japanese. Concerning both faculties together, the increase in publishing frequency for all publication types more than tripled from 4.01 to 12.38. This was largely driven by changes in conference paper publication for the pharmaceutical sciences faculty, where English publication increased 2,775% (0.06 to 1.7 papers per faculty member per year) and Japanese language publication 258% (1.33 to 4.77). While conference paper publication did increase for the medical sciences, its change in total publication frequency was largely driven by ‘other’ types of publication, which increased from 0.51 publications per faculty member per year in 1979–1980 to 5.41 in 2019–2020, largely driven by Japanese language publication.

Conclusion
In 2019–2020, pharmaceutical sciences faculty members largely published original papers in English, so postgraduate education should consider the future likelihood of graduates needing to publish in English.
Utility of in vitro release testing (IVRT) to assess ‘sameness’ of 1% clotrimazole creams for use as a biowaiver
Authors: Wellington Hannah , Rath Seeprarani , Abboo Sagaran , Kanfer Isadore 
Published: November 2023

AbstractThe October 2022 draft United States Food and Drug Administration (FDA) guidance presents an option of in vitro release test (IVRT) studies as a biowaiver for topical drug products submitted in abbreviated new drug applications (ANDAs). However, the product-specific guidance (PSG) for 1% clotrimazole (CLZ) topical cream does not provide an in vitro option for biowaiver and requires a clinical endpoint study to demonstrate bioequivalence (BE). Therefore, the main objective was to use IVRT to investigate pharmaceutical equivalence of several 1% CLZ topical creams from two countries — South Africa (SA) and Canada. This investigation aims at demonstrating the utility of IVRT to determine ‘sameness’ and/or differences between topical creams containing 1% CLZ and the potential of IVRT for supporting biowaivers, thereby obviating the necessity to conduct clinical endpoint studies in patients. A validated IVRT method was applied to conduct comparative IVRT runs on five generic products marketed in SA and one Canadian generic, which were compared against a relevant comparator product from their country of origin in accordance with the FDA’s acceptance criteria of 75–133.33%. All five SA-marketed generic creams showed pharmaceutical inequivalence to the SA comparator product indicating Q1/Q2/Q3 differences. Despite containing the same excipients as both comparator products, the Canadian generic showed substantially lower release rate compared to the comparator products which could be attributed to Q2/Q3 differences. The IVRT method displayed the requisite ability to assess the various 1% CLZ creams and confirmed the potential of the IVRT method to support a biowaiver for 1% CLZ topical creams.

P300 in peripheral neuropathy: cognitive functions assessment and gender effect
Authors: Mejahed Mohammad , Ibrahim Amira M. , Haydara Tamer , Ragab Salma , Gabr Takwa A. 
Published: November 2023

Abstract
Background
Patients with peripheral neuropathy (PN) have subtle central pathology that might contribute to cognitive impairment. P300 is a cognitive potential that is connected to both sensory and cognitive processes. Subjects with neurocognitive disorders have considerably longer P300 latency. This study aims to investigate P300's potential as a marker of early-stage cognitive deterioration in PN patients and also, the effect of gender on P300 in patients with PN.

Results
A study group of 60 subjects with PN of various etiologies and no other neurological conditions was included, in addition to, a control group of 40 volunteers with normal hearing sensitivity and no central or peripheral auditory neurological abnormalities. P300 response showed significant delayed latencies in study group when compared to control group. Male group had significant delayed P300 latencies in comparison to female group. As regard P300 amplitude, male group showed no statistically significant differences in comparison to female group.

Conclusions
Although patients with PN apparently have normal cognitive function, the results in this study revealed the possibility of subtle cognitive impairment. Cognitive functions are affected in both axonal PN and demyelinating PN, however there were no differences found between the two subgroups. Auditory evoked potentials, particularly P300 can be used easily for early detection of subclinical cognitive impairment before appearance of any neurological manifestations. P300 latencies are more important than amplitudes and may be used alone or in addition to amplitudes in cognitive function assessment.
Impacts of repeated social defeat on behavior and the brain in a cichlid fish

Published: November 2023

ABSTRACT
Social defeat is a powerful experience leading to drastic changes in physiology and behavior, many of which are negative. For example, repeated social defeat in vertebrates results in reduced reproductive success, sickness and behavioral abnormalities that threaten individual survival and species persistence. However, little is known about what neural mechanisms are involved in determining whether an individual is resilient or susceptible to repeated social defeat stress. It also remains unknown whether exclusive use of reactive behaviors after repeated social defeat is maintained over time and impacts future behaviors during subsequent contests. We used a resident–intruder experiment in the African cichlid fish Astatotilapia burtoni to investigate the behavior and neural correlates of these two opposing groups. Behavior was quantified by watching fish during defeat trials and used to distinguish resilient and susceptible individuals. Both resilient and susceptible fish started with searching and freezing behaviors, with searching decreasing and freezing increasing after repeated social defeat. After a 4 day break period, resilient fish used both searching and freezing behaviors during a social defeat encounter with a new resident, while susceptible fish almost exclusively used freezing behaviors. By quantifying neural activation using pS6 in socially relevant brain regions, we identified differential neural activation patterns associated with resilient and susceptible fish and found nuclei that co-varied and may represent functional networks. These data provide the first evidence of specific conserved brain networks underlying social stress resilience and susceptibility in fishes.

Published: November 2023

Objective: To retrospectively evaluate the comorbidities, treatment patterns and outcomes of Medicare enrolees who developed venous leg ulcers (VLUs). Method: Medicare Limited Data Standard Analytic Hospital Inpatient and Outpatient Department Files were used to follow patients who received medical care for a VLU between 1 October 2015 and 2 October 2019. Patients diagnosed with chronic venous insufficiency (CVI) and a VLU were propensity matched into four groups based on their treatment regimen. Episode claims were used to document demographics, comorbidities and treatments of Medicare enrolees who developed VLUs, as well as important outcomes, such as time to ulcer closure, rates of complications and hospital utilisation rates. Outcomes were compared across key propensity-matched groups. Results: In total, 42% of Medicare enrolees with CVI (n=1,225,278), developed at least one VLU during the study, and 79% had their episode claim completed within one year. However, 59% of patients developed another VLU during the study period. This analysis shows that only 38.4% of VLU episodes received documented VLU conservative care treatment. Propensity-matched episodes that received an advanced treatment or high-cost skin substitutes for a wound which had not progressed by 30 days demonstrated the best outcomes when their cellular, acellular, matrix-like product (CAMP) treatment was applied weekly or biweekly (following parameters for use). Complications such as rates of infection (33%) and emergency department visits (>50%) decreased among patients who received an advanced treatment (following parameters for use). Conclusion: Medicare enrolees with CVI have diverse comorbidities and many do not receive sufficient management, which contributes to high rates of VLUs and subsequent complications. Medicare patients at risk of a VLU who receive early identification and advanced CAMP treatment demonstrated improved quality of life and significantly reduced healthcare resource utilisation.
Whole versus hole: enabling community nurses to implement holistic wound care
Authors: Moattari Marzieh , King Emily C , Ruco Arlinda 
Published: November 2023

Objective: To improve wound-related quality of life (QoL) in clients with hard-to-heal wounds in their lower limbs and to increase referrals to multidisciplinary teams in the management of care for these clients. Method: This was a quality improvement project with a two-group pretest–posttest interventional evaluation design. We implemented a package of interventions including the WounDS app, education related to wound care, and client engagement through a QoL self-assessment. Wound-related QoL was measured using the Cardiff Wound Impact Schedule and referrals to the multidisciplinary team were tracked through chart audits. We explored nurses' experiences with the interventions through semi-structured interviews. Results: Clients' average ratings for ‘wellbeing’, ‘physical symptoms and daily living’, and ‘overall QoL’ improved by 27%, 38% and 54%, respectively. The number of referrals increased by 78% post intervention. Nurses described the interventions as effective strategies that motivated them to implement a holistic approach to care. Conclusion: The project was successful in creating a culture shift to practice holistic wound care. This package of interventions (WounDS app, education and client self-assessment of QoL) led to improvements in the QoL of clients with hard-to-heal wounds. Further studies are needed to generalise the findings. Strategies for sustainability include forming a champion group and providing the education and decision supports based on nurses' educational needs assessment.
