Published: February 2021

Background: Cartilage degeneration is a common issue in patients with chronic lateral ankle instability. However, there are limited studies regarding the effectiveness of lateral ligament surgery on preventing talar and subtalar joint cartilage from further degenerative changes. Purpose: To longitudinally evaluate talar and subtalar cartilage compositional changes using magnetic resonance imaging T2* mapping in anatomic anterior talofibular ligament (ATFL)–repaired and ATFL-reconstructed ankles and to compare them with measures in asymptomatic controls. Study Design: Cohort study; Level of evidence, 3. Methods: Between January 2015 and December 2016, patients with chronic lateral ankle instability who underwent anatomic ATFL repair (n = 19) and reconstruction (n = 20) were prospectively recruited. Patients underwent 3.0-T magnetic resonance imaging at baseline and 3-year follow-up. As asymptomatic controls, 21 healthy volunteers were recruited and underwent imaging at baseline. Talar dome cartilage was divided into (1) medial anterior, central, and posterior and (2) lateral anterior, central, and posterior. Posterior subtalar cartilage was divided into (1) central talus and calcaneus and (2) lateral talus and calcaneus. Ankle function was assessed using the American Orthopaedic Foot & Ankle Society scores. Results: There were significant increases in T2* values in medial and lateral posterior and central talus cartilage from baseline to 3-year follow-up in patients who underwent repair. T2* values were significantly higher in ATFL-repaired ankles at follow-up for all cartilage regions of interest, except medial and lateral anterior and lateral central, compared with those in healthy controls. From baseline to 3-year follow-up, ATFL-reconstructed ankles had a significant increase in T2* values in lateral central and posterior cartilage. T2* values in ATFL-reconstructed ankles at follow-up were elevated in all cartilage regions of interest, except medial and lateral anterior, compared with those in healthy controls. ATFL-repaired ankles showed a greater decrease of T2* values from baseline to follow-up in lateral calcaneus cartilage than did ATFL-reconstructed ankles ( P = .031). No significant differences in American Orthopaedic Foot & Ankle Society score were found between repair and reconstruction procedures (mean ± SD, 19.11 ± 7.45 vs 16.85 ± 6.24; P = .311). Conclusion: Neither anatomic ATFL repair nor reconstruction could prevent the progression of talar dome and posterior subtalar cartilage degeneration; however, ankle function and activity levels were not affected over a short period. Patients who underwent ATFL repair exhibited lower T2* values in the lateral calcaneus cartilage than did those who underwent reconstruction.

Published: February 2021

AbstractIn this paper, a dielectric modulated double source trench gate tunnel FET (DM-DSTGTFET) based on biosensor is proposed for the detection of biomolecules. DM-DSTGTFET adopts double source and trench gate to enhance the on-state current and to generate bidirectional current. In the proposed structure, two cavities are etched over 1 nm gate oxide for biomolecules filling. A 2D simulation in the Technology Computer-Aided Design (TCAD) is adopted for the analysis of sensitivity study. The results show that under low supply voltage, the current sensitivity of the DM-DSTGTFET is as high as 1.38 × 105, and the threshold voltage sensitivity can reach 1.2 V. Therefore, the DM-DSTGTFET biosensor has good application prospects due to its low power consumption and high sensitivity.

Abstract
Background
High-pressure processing (HPP) is a commonly used technique in the food industry to inactivate pathogens, including L. monocytogenes. It has been shown that L. monocytogenes is able to recover from HPP injuries and can start to grow again during long-term cold storage. To date, the gene expression profiling of L. monocytogenes during HPP damage recovery at cooling temperature has not been studied. In order identify key genes that play a role in recovery of the damage caused by HPP treatment, we performed RNA-sequencing (RNA-seq) for two L. monocytogenes strains (barotolerant RO15 and barosensitive ScottA) at nine selected time points (up to 48 h) after treatment with two pressure levels (200 and 400 MPa).

Results
The results showed that a general stress response was activated by SigB after HPP treatment. In addition, the phosphotransferase system (PTS; mostly fructose-, mannose-, galactitol-, cellobiose-, and ascorbate-specific PTS systems), protein folding, and cobalamin biosynthesis were the most upregulated genes during HPP damage recovery. We observed that cell-division-related genes (divIC, dicIVA, ftsE, and ftsX) were downregulated. By contrast, peptidoglycan-synthesis genes (murG, murC, and pbp2A) were upregulated. This indicates that cell-wall repair occurs as a part of HPP damage recovery. We also observed that prophage genes, including anti-CRISPR genes, were induced by HPP. Interestingly, a large amount of RNA-seq data (up to 85%) was mapped to Rli47, which is a non-coding RNA that is upregulated after HPP. Thus, we predicted that Rli47 plays a role in HPP damage recovery in L. monocytogenes. Moreover, gene-deletion experiments showed that amongst peptidoglycan biosynthesis genes, pbp2A mutants are more sensitive to HPP.

Conclusions
We identified several genes and mechanisms that may play a role in recovery from HPP damage of L. monocytogenes. Our study contributes to new information on pathogen inactivation by HPP.
Rate of neuropathic progression in hereditary transthyretin amyloidosis with polyneuropathy and other peripheral neuropathies: a systematic review and meta-analysis
Authors: Lin Xiaochen , Yarlas Aaron , Vera-Llonch Montserrat , Baranwal Nishtha , Biber Josh , Brown Duncan , Vogt Braden , Karam Chafic 
Published: February 2021

Abstract
Background
We aimed to compare neuropathic progression rate between hereditary transthyretin amyloidosis with polyneuropathy (ATTRv-PN) and other peripheral neuropathies, including diabetic peripheral neuropathy (DPN) and Charcot-Marie-Tooth disease (CMT).

Methods
Literature searches identified studies reporting neuropathic progression, measured by Neuropathy Impairment Score (NIS) or NIS-Lower Limbs (NIS-LL). Our study also included unpublished data from a clinical registry of patients who were diagnosed with different peripheral neuropathies and seen at the Oregon Health & Science University (OHSU) during 2016–2020. Meta-analysis and meta-regression models examined and compared annual progression rates, calculated from extracted data, between studies of ATTRv-PN and other peripheral neuropathies.

Results
Data were synthesized from 15 studies in which NIS and/or NIS-LL total scores were assessed at least twice, with ≥12 weeks between assessments, among untreated patients with ATTRv-PN or other peripheral neuropathies. Meta-analysis models yielded that the annual progression rate in NIS total scores was significantly different from zero for studies in ATTRv-PN and CMT (11.77 and 1.41; both P < 0.001), but not DPN (− 1.96; P = 0.147). Meta-regression models showed significantly faster annual progression in studies in ATTRv-PN, which statistically exceeded that in other peripheral neuropathies by 12.45 points/year for NIS, and 6.96 for NIS-LL (both P < 0.001).

Conclusions
Peripheral nervous function deteriorates more rapidly in patients with ATTRv-PN than for other peripheral neuropathies. These findings may improve understanding of the natural history of neuropathy in ATTRv-PN, facilitate early diagnosis, and guide the development of assessment tools and therapies specifically targeting neuropathic progression in this debilitating disease.
Neonatal near misses and associated factors among mother’s who give a live neonate at Hawassa City governmental hospitals, 2019: a facility based cross-sectional study design

Published: February 2021

Abstract
Background
Neonatal near miss is a neonate who nearly died but survived from a severe complication occurred during pregnancy, birth or within 0–28 days of extra-uterine life. However, there is no available data that quantifies the magnitude of neonatal near miss (NNM) in Ethiopia where there is high prevalence of neonatal mortality. Therefore, this study is designed to provide information about the magnitude and associated factors of neonatal near miss among women who give a live birth at Hawassa City Governmental hospitals, 2019.

Methods
A facility based cross-sectional study design was conducted on 604 mothers who gave live neonates at Adare General Hospital and Hawassa University Comprehensive and Specialized Hospital from May 9, 2019 to June 7, 2019. Face to face interviewer administered structured questionnaire with a supplementation of maternal and neonatal medical records with checklists were used to collect the data. Data were coded and entered in to Epi data version 3.1 and then exported to the Statistical Package for Social Science IBM version 25 for analysis. Descriptive statistics was run and the data were presented using frequency tables and figure. The bi-variable and multivariable logistic regression was used to identify the possible factors of neonatal near miss. Finally, Adjusted Odds Ratio and 95% Confidence Intervals were used to declare statsticall significance.

Result
Among all 604 selected live births an overall proportion of NNM cases, 202 (33.4%) (95% CI: 29.7–37.1%) was obtained at Hawassa City Government Hospitals. Respiratory distress 158 (94%) and infection or sepsis 138 (84%) were found to be the leading causes of NNM cases in our study. Governmental and non-governmental employed mother (AOR = 3.05, 95% CI: 1.46–6.44) and Cesarean Section delivery (AOR = 1.89, (95% CI: 1.25–2.83)) were positively significantly associated with neonatal near miss. Whereas, pregnancy induced Hypertension (AOR = 0.43, 95%CI: 0.27–0.69) was negatively associated with neonatal near miss.

Conclusion
This study revealed relatively high prevalence of NNM in the study areas. Employed women, pregnancy induced hypertension and cesarean section mode of delivery were found to be independent factors affecting the prevalence of NNM cases. Therefore, HUCSH and Adare general Hospitals should focus on proving quality antenatal care and prevention of occupational related problems among pregnant women.
Male partner involvement in birth preparedness, complication readiness and obstetric emergencies in Sub-Saharan Africa: a scoping review
Authors: Forbes Faye , Wynter Karen , Zeleke Berihun M. , Fisher Jane 
Published: February 2021

Abstract
Background
Maternal mortality remains a pressing concern across Sub-Sahara Africa. The ‘Three Delays Model’ suggests that maternal deaths are a consequence of delays in: seeking care, reaching medical care and receiving care. Birth Preparedness and Complication Readiness (BPCR) refers to a plan organised during pregnancy in preparation for a normal birth and in case of complications. Male partners in many Sub-Saharan African communities could play a pivotal role in a woman’s ability to prepare for birth and respond to obstetric complications. This review aimed identify: the extent and quality of research performed on the topic of male partner involvement in BPCR in Sub-Saharan Africa; the degree to which populations and geographic areas are represented; how male partner involvement has been conceptualized; how male partners response to obstetric complications has been conceptualised; how the variation in male partners involvement has been measured and if any interventions have been performed.

Methods
In this scoping review, articles were identified through a systematic search of databases MEDLINE, EMBASE and Maternity and Infant Care and a manual scan of relevant papers, journals and websites. All authors contributed to the screening process and a quality assessment using the Kmet checklist. The PRISMA checking list for Scoping Reviews was used to guide the search, data charting and reporting of the review The protocol was registered with PROSPERO (ID: CRD42019126263).

Results
Thirty-five articles met inclusion criteria, reporting: 13 qualitative, 13 cross-sectional, 5 mixed method and 4 intervention studies. Data were contributed by approximately 14,550 participants (numbers were not always reported for focus groups) including: women who were pregnant or who had experienced pregnancy or childbirth within the previous 3 years, their male partners and key informants such as health workers and community leaders.

Conclusions
The diversity of study designs, aims and source countries in this body of literature reflects an emerging stage of research; as a result, the review yielded strong evidence in some areas and gaps in others. Male partner’s involvement in BPCR and responding to obstetric emergencies can be conceptualised as being centrally involved in responding to complications and having some role in preparing for birth through their position in the chain of decisions and provision of logistic support. However, their knowledge of pregnancy complications and level of preparation for birth is low, suggesting they are making decisions without being fully informed. There is limited evidence on interventions to improve their knowledge. Future research efforts should be focused on producing standardised, culturally appropriate, higher level evidence.

Published: February 2021

Abstract
Background
The goal of this study is to disclose the clinically significant genomic alterations in the Chinese and Western patients with intrahepatic cholangiocarcinoma.

Methods
A total of 86 Chinese patients were enrolled in this study. A panel of 579 pan-cancer genes was sequenced for the qualified samples from these patients. Driver genes, actionability, and tumor mutational burden were inferred and compared to a cohort of Western patients.

Results
Totally, 36 and 12 driver genes were identified in the Chinese and Western cohorts, respectively. Of them, seven driver genes (IDH1, KRAS, TP53, BAP1, PBRM1, ARID1A, and NRAS) were shared by the two cohorts. Four driver genes (SPTA1, ARID2, TP53, and GATA1) were found significantly correlated with the tumor mutational burden. For both cohorts, half of the patients had actionable mutations. The two cohorts shared the most actionable genes but differed much in their frequency. Though KRAS mutations were at the first and second actionable rank respectively for the Chinese and Western populations, they were still at a relatively low level of actionable evidence.

Conclusions
The study on the clinical significance of genomic alterations directs the future development of precision medicine for intrahepatic cholangiocarcinoma treatment.

Abstract
Background
p63, a member of the p53 gene family, is an important regulator for epithelial tissue growth and development. ∆Np63α is the main isoform of p63 and highly expressed in Non-melanoma skin cancer (NMSC). Extracellular signal-regulated kinase 3 (ERK3) is an atypical mitogen-activated protein kinase (MAPK) whose biochemical features and cellular regulation are distinct from those of conventional MAPKs such as ERK1/2. While ERK3 has been shown to be upregulated in lung cancers and head and neck cancers, in which it promotes cancer cell migration and invasion, little is known about the implication of ERK3 in NMSCs.

Methods
Fluorescent immunohistochemistry was performed to evaluate the expression levels of ΔNp63α and ERK3 in normal and NMSC specimens. Dunnett’s test was performed to compare mean fluorescence intensity (MFI, indicator of expression levels) of p63 or ERK3 between normal cutaneous samples and NMSC samples. A mixed effects (ANOVA) test was used to determine the correlation between ΔNp63α and ERK3 expression levels (MFI). The regulation of ERK3 by ΔNp63α was studied by qRT-PCR, Western blot and luciferase assay. The effect of ERK3 regulation by ΔNp63α on cell migration was measured by performing trans-well migration assay.

Results
The expression level of ∆Np63α is upregulated in NMSCs compared to normal tissue. ERK3 level is significantly upregulated in AK and SCC in comparison to normal tissue and there is a strong positive correlation between ∆Np63α and ERK3 expression in normal skin and skin specimens of patients with AK, SCC or BCC. Further, we found that ∆Np63α positively regulates ERK3 transcript and protein levels in A431 and HaCaT skin cells, underlying the upregulation of ERK3 expression and its positive correlation with ∆Np63α in NMSCs. Moreover, similar to the effect of ∆Np63α depletion, silencing ERK3 greatly enhanced A431 cell migration. Restoration of ERK3 expression under the condition of silencing ∆Np63α counteracted the increase in cell migration induced by the depletion of ∆Np63α. Mechanistically, ERK3 inhibits the phosphorylation of Rac1 G-protein and the formation of filopodia of A431 skin SCC cells.

Conclusions
ERK3 is positively regulated by ∆Np63α and mediates the role of ∆Np63α in suppressing cell migration in NMSC.

Abstract
Background
The adoption and evaluation of good practices in food handling in food service are essential to minimizing foodborne diseases. The present study aimed to evaluate food safety knowledge, attitudes, and practices of food handlers in schools in Vitória, Brazil.

Methods
A cross-sectional study was carried out in the school food services of the municipal network of Vitória-ES. The sample of food handlers was obtained by convenience and comprised food handlers involved with preparation and other kitchen-related activities. The instrument consisted of a structured questionnaire with 36 six questions that included sociodemographic characteristics, knowledge, attitudes, and practices (KAP) related to good practices and food safety. The questionnaire was answered by 172 food handlers. Pearson correlation test, T-test, Tukey’s test and multiple linear regression analysis were conducted. Data entry and analysis were done using SPSS v.20 software.

Results
Most of the participants were female (96.5%, n = 166), were 40 to 49 years old (44.8%, n = 78), attended high school (57.9%, n = 99), had up to 5 years of experience in the role (39.5%, n = 68). Some of them had participated at least 4 times in training (74.4%, n = 128) of which the most recent session had occurred within 3 months (52.0%, n = 44). The lowest score was obtained for knowledge (7.1 ± 1.22). All the models presented significant results for the F-test. This result show good model fit and results ranging from 1.5 to 2.5 on the Durbin Watson test of residual autocorrelation. The linear regression analysis allowed us to identify that the knowledge score increased with experience, but it was significant only for those who had spent up to 10 years in the role. The knowledge score was associated with experience and training time. Attitudes were significantly related to the schooling and training time. The increase in the classification of practices is shown only through a classification of attitudes.

Conclusions
Although the food handlers’ knowledge level in general was considered as sufficient, it was inferior to their scores for attitudes and practices regarding certain food safety concepts. Food safety training is ongoing in these units and covers the main aspects that favour the transformation of knowledge into appropriate attitudes and practices.
Clinical features of anti-synthetase syndrome associated interstitial lung disease: a retrospective cohort in China
Authors: Zhan Xi , Yan Wei , Wang Ying , Li Qing , Shi Xuhua , Gao Yanli , Ye Qiao 
Published: February 2021

Abstract
Background
Anti-synthetase syndrome (ASSD) is a chronic autoimmune condition characterized by antibodies directed against an aminoacycl transfer RNA synthetase (ARS) along with a group of clinical features including the classical clinical triad: inflammatory myopathy, arthritis, and interstitial lung disease (ILD). ASSD is highly heterogenous due to different organ involvement, and ILD is the main cause of mortality and function loss, which presents as different patterns when diagnosed. We designed this retrospective cohort to describe the clinical features and disease behaviour of ASSD associated ILD.

Methods
Data of 108 cases of ASSD associated ILD were retrospectively collected in Beijing Chaoyang Hospital from December 2017 to March 2019. Data were obtained from the Electronic Medical Record system. Patients were divided into 5 groups according to distinct aminoacyl tRNA synthetase (ARS) antibodies.

Results
Overall, 108 consecutive patients were recruited. 33 were JO-1 positive, 30 were PL-7 positive, 23 were EJ positive, 13 were PL-12 positive and 9 were OJ positive. The JO-1 (+) group had a significant higher rate of mechanic’s hand (57.6%) than other 4 groups. Polymyositis/dermatomyositis (PM/DM) was diagnosed in 25 (23.1%) patients and no difference was observed among the 5 groups. The PL-7 (+) group had a higher frequency of UIP pattern (13.3%) than the other 4 groups but the difference was not significant, and the EJ (+) group had the most frequent OP pattern (78.2%), which was significantly higher than the PL-7 (+) (P < 0.001) and PL-12 (+) groups (P = 0.025). The median follow-up time was 10.7 months, during which no patients died. All received prednisone treatment, with or without immunosuppressants. At the 6-month follow-up, 96.3% of all patients (104/108) had a positive response to therapy, the JO-1 (+) and EJ (+) groups had a significantly higher improvement of forced vital capacity than the other 3 groups (P < 0.05), and the PL-7 group had the lowest FVC improvement (P < 0.05). The JO-1 (+) group and EJ (+) group had significantly higher anti-Ro-52 positive occurrence than the other 3 groups (P < 0.05).

Conclusion
Anti PL-7 antibody had the same frequency as anti-JO-1 in ASSD-ILD, in which the ILD pattern was different with distinct anti-ARS antibodies. Most ASSD-ILD had a positive response to steroid therapies, with or without immunosuppressants. The PL-7 (+) group had the highest occurrence of UIP pattern, and a significantly lower response to therapy.
