Published: January 2021

Objectives: To report 2 children with acute hepatic myelopathy after hepatitis A infection who recovered completely after living donor liver transplantation. Methods: All the children admitted into liver intensive care unit (LICU) from November 1st 2018 to 31st October 2019, were evaluated for the neurological features. The data was collected from the admission register of the LICU unit in children below 15 years age. Medical records of these children were reviewed and data collected. Established clinical criteria were used to categorize the various grades of hepatic encephalopathy/myelopathy. Results: 37 children were seen over 1-year period between 6 months to 15 years age. There were 24 male(64.9%) and 13 females. Acute liver failure was seen in 19 (51.3%) and acute on chronic liver failure in 18 (48.7%). There were 10 cases of hepatitis A in acute liver failure group,10 of 19 cases (52.6%), while Wilson’s disease and undetermined etiology group formed the chronic group. 2 cases of hepatic myelopathy were seen in acute liver failure following hepatitis A infection. Both these children underwent live liver donor transplantation and recovered completely. Further in hepatitis A group,3 children had spontaneous recovery, 4 died and 1 child was discharged with end of life care. Overall out of all 37 children with liver failure,20 (54%) were discharged, 6 (16.2%) were advised end of life care and 11 (29.8%) died. Conclusion: Two cases (10.5%) of reversible hepatic myelopathy were seen in acute liver failure group of 19 cases. 18 out of 37 (48.6%) children had residual neurological features at discharge time.

Published: January 2021

Introduction: The coronavirus disease 2019 (COVID-19) pandemic and subsequent restrictions on dental services have had a significant impact on the provision of dental care in Australia and around the world. Objectives: To investigate the impact of COVID-19 on medications prescribed by dentists under the Australian Pharmaceutical Benefits Scheme (PBS). Methods: Data on the number of dental prescriptions dispensed for all medications listed on the PBS Dental Schedule, from January 2019 to June 2020, were extracted from publicly available data sets. Analysis of prescription trends was performed for 1) total medications, 2) each major medication class, and 3) individual medications. The number of prescriptions dispensed in each month from January 2020 to June 2020 was compared to the same month in 2019 to determine the relative (percentage) change, and z statistics were used to determine whether changes were statistically significant. Results: There was a significant decrease in dental prescriptions in April 2020 compared to April 2019 (14,785, 18%; P < 0.05). Decreases in prescriptions for antibiotics (10,512, 16%; P < 0.05) and opioid analgesics (3,129, 18%; P < 0.05) were smaller compared to other major medication classes. There was a significant increase in June 2020, compared with June 2019, for prescriptions of amoxicillin with clavulanic acid (4,903, 20%; P < 0.05), tramadol (89, 46%; P < 0.05), and oxycodone (381, 73%; P < 0.05). Conclusion: Dental service restrictions during COVID-19 likely drove an unmet need for routine dental treatment, which had significant implications for public oral health following easing of restrictions. During the initial surge and subsequent lockdown, antibiotics and opioid analgesics may have been used an as alternative to routine operative treatment. Continued professional guidance is required to ensure dental prescribing remains evidence based during the pandemic period. Knowledge Transfer Statement: The COVID-19 pandemic and subsequent restrictions on dental practice have had a profound impact on the provision of dental care in Australia and elsewhere in the world. In this context, population-level medication surveillance is important to identify and respond to changes in prescribing patterns that have arisen due to COVID-19 and restrictions on the provision of dental care. This research is particularly important for governments, regulators, and professional associations to ensure therapeutic guidelines and recommendations during the pandemic period remain relevant and evidence based.

Published: January 2021

Introduction: Systemic sclerosis–associated interstitial lung disease accounts for up to 20% of mortality in these patients and has a highly variable prognosis. Functional respiratory imaging, a quantitative computed tomography imaging technique which allows mapping of regional information, can provide a detailed view of lung structures. It thereby shows potential to better characterize this disease. Purpose: To evaluate the use of functional respiratory imaging quantitative computed tomography in systemic sclerosis–associated interstitial lung disease staging, as well as the relationship between short-term changes in pulmonary function tests and functional respiratory imaging quantitative computed tomography with respect to disease severity. Materials and methods: An observational cohort of 35 patients with systemic sclerosis was retrospectively studied by comparing serial pulmonary function tests and in- and expiratory high-resolution computed tomography over 1.5-year interval. After classification into moderate to severe lung disease and limited lung disease (using a hybrid method integrating quantitative computed tomography and pulmonary function tests), post hoc analysis was performed using mixed-effects models and estimated marginal means in terms of functional respiratory imaging parameters. Results: At follow-up, relative mean forced vital capacity percentage change was not significantly different in the limited (6.37%; N = 13; p = 0.053) and moderate to severe disease (−3.54%; N = 16; p = 0.102) groups, respectively. Specific airway resistance decreased from baseline for both groups. (Least square mean changes −25.11% predicted ( p = 0.006) and −14.02% predicted ( p = 0.001) for limited and moderate to severe diseases.) In contrast to limited disease from baseline, specific airway radius increased in moderate to severe disease by 8.57% predicted ( p = 0.011) with decline of lower lobe volumes of 2.97% predicted ( p = 0.031). Conclusion: Functional respiratory imaging is able to differentiate moderate to severe disease versus limited disease and to detect disease progression in systemic sclerosis.

Published: January 2021

Purpose: To report the 12-month results of laser (treatment G1) versus intravitreal bevacizumab combined with laser (treatment G2) in patients with diffuse diabetic macular edema (DME). Methods: In this single-center randomized independent controlled trial, 32 patients were randomized to G1 ( n = 15) or G2 ( n = 17). In G1, laser was given at baseline and then pro re nata (PRN). In G2, three intravitreal bevacizumab (1.25 mg) injections were given once every 6 weeks, then laser and then PRN. Analysis was performed by treatment as administered. This study was registered in clinicaltrials.gov as NCT01572350 and EU Clinical Trial Registry as 2009-014654-15. Results: G2 was superior to G1 improving best corrected visual acuity (BCVA) with respect baseline (+8.0 vs + 3.0; p < 0.01). At month 12, a significantly greater proportion of patients had a BCVA letter score >15 and >73 in G2 (3 of 15 (20%) and 8 of 15 (53%), respectively) versus G1 (1 of 17 (6%) and 4 of 18 (23%), respectively). Health-related quality of life, assessed through National Eye Institute Visual Function Questionnaire, at 12 months was statistically indistinguishable between both groups. Conclusion: G2 provided superior visual acuity gains over G1 in patients with visual impairment due to center-involving diffuse DME, associated with significant gains in VFQ-25 scores.

Abstract
Distinguishing chronic lymphoproliferative disorders of NK cells (CLPD-NK) from reactive NK-cell expansion is challenging. We assessed the value of killer immunoglobulin-like receptor(KIR) phenotyping and targeted high-throughput sequencing in a cohort of 114 consecutive patients with NK cell proliferation, retrospectively assigned to a CLPD-NK group (n = 46) and a reactive NK group (n = 68). We then developed an NK-cell clonality score combining flow cytometry and molecular profiling with a positive predictive value of 93%. STAT3 and TET2 mutations were respectively identified in 27% and 34% of the patients with CLPD-NK, constituting a new diagnostic hallmark for this disease. TET2-mutated CLPD-NK preferentially exhibited a CD16low phenotype, more frequently displayed a lower platelet count, and was associated with other hematologic malignancies such as myelodysplasia. To explore the mutational clonal hierarchy of CLPD-NK, we performed whole-exome sequencing of sorted, myeloid, T, and NK cells and found that TET2 mutations were shared by myeloid and NK cells in 3 of 4 cases. Thus, we hypothesized that TET2 alterations occur in early hematopoietic progenitors which could explain a potential link between CLPD-NK and myeloid malignancies. Finally, we analyzed the transcriptome by RNA sequencing of 7 CLPD-NK and evidenced 2 groups of patients. The first group displayed STAT3 mutations or SOCS3 methylation and overexpressed STAT3 target genes. The second group, including 2 TET2-mutated cases, significantly underexpressed genes known to be downregulated in angioimmunoblastic T-cell lymphoma. Our results provide new insights into the pathogenesis of NK-cell proliferative disorders and, potentially, new therapeutic opportunities.
Identify RNA-associated subcellular localizations based on multi-label learning using Chou’s 5-steps rule

Published: January 2021

Abstract
Background
Biological functions of biomolecules rely on the cellular compartments where they are located in cells. Importantly, RNAs are assigned in specific locations of a cell, enabling the cell to implement diverse biochemical processes in the way of concurrency. However, lots of existing RNA subcellular localization classifiers only solve the problem of single-label classification. It is of great practical significance to expand RNA subcellular localization into multi-label classification problem.

Results
In this study, we extract multi-label classification datasets about RNA-associated subcellular localizations on various types of RNAs, and then construct subcellular localization datasets on four RNA categories. In order to study Homo sapiens, we further establish human RNA subcellular localization datasets. Furthermore, we utilize different nucleotide property composition models to extract effective features to adequately represent the important information of nucleotide sequences. In the most critical part, we achieve a major challenge that is to fuse the multivariate information through multiple kernel learning based on Hilbert-Schmidt independence criterion. The optimal combined kernel can be put into an integration support vector machine model for identifying multi-label RNA subcellular localizations. Our method obtained excellent results of 0.703, 0.757, 0.787, and 0.800, respectively on four RNA data sets on average precision.

Conclusion
To be specific, our novel method performs outstanding rather than other prediction tools on novel benchmark datasets. Moreover, we establish user-friendly web server with the implementation of our method.

Abstract
Background
Carbon monoxide causes electrical, functional, and morphological changes in the heart. It is unclear, however, whether the indicators of myocardial damage can predict the patient’s prognosis after carbon monoxide poisoning. This retrospective study aimed to investigate the relationship between the carboxyhemoglobin level and electrocardiographic (ECG) changes and whether the ECG changes and troponin I levels are related to the patient’s prognosis after carbon monoxide poisoning.

Methods
Carboxyhemoglobin, troponin I, and ECG parameters were measured in 70 patients with carbon monoxide poisoning. The QT and RR intervals were measured for each ECG lead in all patients, and the corrected QT interval and corrected QT dispersion were calculated.

Results
The correlation between the maximum corrected QT interval and the carboxyhemoglobin level was significant (P = 0.0072, R2 = 0.1017), as were the relationships between QT dispersion and carboxyhemoglobin (P < 0.001, R2 = 0.2358) and the corrected QT dispersion and carboxyhemoglobin (P < 0.001, R2 = 0.2613). The multivariate logistic analysis showed that the significant predictors of sequential disability were corrected QT dispersion (P = 0.0042), and troponin I level (P = 0.0021).

Conclusions
Patients’ prognosis following carbon monoxide poisoning can be predicted based on corrected QT dispersion and the troponin I level. Patients with myocardial damage should be monitored not only for their cardiovascular outcome but also for their neurological outcome and their prognosis.

Abstract
Background
The actual SARS-CoV-2 outbreak caused a highly transmissible disease with a tremendous impact on elderly people. So far, few studies focused on very elderly patients (over 80 years old). In this study we examined the clinical presentation and the outcome of the disease in this group of patients, admitted to our Hospital in Rome.

Methods
This is a single-center, retrospective study performed in the Sant’Andrea University Hospital of Rome. We included patients older than 65 years of age with a diagnosis of COVID-19, from March 2020 to May 2020, divided in two groups according to their age (Elderly: 65–80 years old; Very Elderly > 80 years old). Data extracted from the each patient record included age, sex, comorbidities, symptoms at onset, the Pneumonia Severity Index (PSI), the ratio of the partial pressure of oxygen in arterial blood (PaO2) to the inspired oxygen fraction (FiO2) (P/F) on admission, laboratory tests, radiological findings on computer tomography (CT), length of hospital stay (LOS), mortality rate and the viral shedding.
The differences between the two groups were analyzed by the Fisher’s exact test or the Wilcoxon signed-rank test for categorical variables and the Mann-Whitney U test for continuous variables. To assess significance among multiple groups of factors, we used the Bonferroni correction.
The survival time was estimated by Kaplan-Meier method and Log Rank Test. Univariate and Multivariate logistic regression were performed to estimate associations between age, comorbidities, provenance from long-stay residential care homes (LSRCH) s and clinical outcomes.

Results
We found that Very Elderly patients had an increased mortality rate, also due to the frequent occurrence of multiple comorbidities. Moreover, we found that patients coming from LSRCHs appeared to be highly susceptible and vulnerable to develop severe manifestations of the disease.

Conclusion
We demonstrate that there were considerable differences between Elderly and Very Elderly patients in terms of inflammatory activity, severity of disease, adverse clinical outcomes. To establish a correct risk stratification, comorbidities and information about provenience from LSRCHs should be considered.
Identifying pre-outbreak signals of hand, foot and mouth disease based on landscape dynamic network marker
Authors: Zhang Xuhang , Xie Rong , Liu Zhengrong , Pan Yucong , Liu Rui , Chen Pei 
Published: January 2021

Abstract
Background
The high incidence, seasonal pattern and frequent outbreaks of hand, foot and mouth disease (HFMD) represent a threat for billions of children around the world. Detecting pre-outbreak signals of HFMD facilitates the timely implementation of appropriate control measures. However, real-time prediction of HFMD outbreaks is usually challenging because of its complexity intertwining both biological systems and social systems.

Results
By mining the dynamical information from city networks and horizontal high-dimensional data, we developed the landscape dynamic network marker (L-DNM) method to detect pre-outbreak signals prior to the catastrophic transition into HFMD outbreaks. In addition, we set up multi-level early warnings to achieve the purpose of distinguishing the outbreak scale. Specifically, we collected the historical information of clinic visits caused by HFMD infection between years 2009 and 2018 respectively from public records of Tokyo, Hokkaido, and Osaka, Japan. When applied to the city networks we modelled, our method successfully identified pre-outbreak signals in an average 5 weeks ahead of the HFMD outbreak. Moreover, from the performance comparisons with other methods, it is seen that the L-DNM based system performs better when given only the records of clinic visits.

Conclusions
The study on the dynamical changes of clinic visits in local district networks reveals the dynamic or landscapes of HFMD spread at the network level. Moreover, the results of this study can be used as quantitative references for disease control during the HFMD outbreak seasons.
Susceptibility pattern of Salmonella enterica against commonly prescribed antibiotics, to febrile-pediatric cases, in low-income countries
Authors: Khadka Priyatam , Thapaliya Januka , Thapa Shovana 
Published: January 2021

Abstract
Background
In most low-income countries, febrile-pediatric-cases are often treated empirically with accessible antibiotics without periodic epidemiological surveillance, susceptibility testing, or minimal lethal dose calculations. With this backdrop, the study was undertaken to evaluate the susceptibility trend of Salmonella enterica against the commonly prescribed antibiotics.

Methods
All isolates of Salmonella enterica were identified by standard protocols of biotyping and serotyping, then tested against antibiotics by the modified Kirby disk-diffusion method. Minimum Inhibitory Concentration (MIC) of isolates was determined by the agar-dilution method and compared with disk diffusion results and on nalidixic-acid sensitive/resistant strains.

Results
Among 1815 febrile-pediatric patients, 90(4.9%) isolates of Salmonella enterica [serovar: Salmonella Typhi 62(68.8%) and Salmonella Paratyphi A 28(31.1%)] were recovered. The incidence of infection was higher among males, age groups 5 to 9, and patients enrolling in the out-patient department (OPD). On the disk-diffusion test, most isolates were sensitive against first-line drugs i.e.cephalosporins, and macrolides. However, against quinolones, a huge percentile 93.3%, of isolates were resistant [including 58 Typhiand 26 Paratyphiserovar] while nearly 14% were resistant against fluoroquinolones.
When MICs breakpoint were adjusted as follows: 4 μg/ml for azithromycin, ≥1 μg/ml for ciprofloxacin, 2 μg/ml for ofloxacin, 8 μg/ml for nalidixic acid, and 1 μg/ml for cefixime, higher sensitivity and specificity achieved. Compared to other tested antibiotics, a low rate of azithromycin resistance was observed. Nevertheless, higher resistance against fluoroquinolones was observed on NARS strain.

Conclusion
Higher susceptibility of Salmonella enterica to the conventional anti-typhoidal drugs (amoxicillin, chloramphenicol, cotrimoxazole, cephotaxime) advocates for its reconsideration. Although, the lower susceptibility against fluoroquinolones among nalidixic-acid-resistant Salmonella (NARS) strain negates its empirical use among the study age group.
Low engagement in HIV services and progress through the treatment cascade among key populations living with HIV in Mozambique: alarming gaps in knowledge of status

Published: January 2021

Abstract
Background
Mozambique has a generalized HIV epidemic of 13.5% among the general population. Early modeling exercises in Mozambique estimate that key populations (KP), defined as men who have sex with men (MSM), female sex workers (FSW), and people who inject drugs (PWID), along with their partners account for about one third of all new infections. There is limited data describing the engagement of KP living with HIV in testing, care and treatment services.

Methods
We conducted a secondary data analysis of HIV-positive participants in the first Bio-behavioral Surveillance (BBS) surveys in Mozambique conducted 2011–2014 in order to assess service uptake and progress though the HIV treatment cascade among MSM, FSW, and PWID. Unweighted pooled estimates were calculated for each key population group.

Results
Among HIV-positive MSM, 63.2% of participants had ever received an HIV test, 8.8% were aware of their status, 6.1% reported having been linked to care, while 3.5% initiated ART and were currently on treatment. Of the HIV-infected FSW participants, 76.5% reported a previous HIV test and 22.4% were previously aware of their status. Linkage to care was reported by 20.1%, while 12.7% reported having initiated ART and 11.8% reported being on treatment at the time of the survey. Among HIV-infected PWID participants, 79.9% had previously received an HIV test, 63.2% were aware of their HIV status, and 49.0% reported being linked to care for their HIV infection. ART initiation was reported by 42.7% of participants, while 29.4% were on ART at the time of the survey.

Conclusion
Among the three high risk populations in Mozambique, losses occurred throughout critical areas of service uptake with the most alarming breakpoint occurring at knowledge of HIV status. Special attention should be given to increasing HIV testing and linkage to ART treatment. Future surveys will provide the opportunity to monitor improvements across the cascade in line with global targets and should include viral load testing to guarantee a more complete picture of the treatment cascade.
