Abstract
Palpation localization is essential for detecting physiological parameters of the radial artery for pulse diagnosis of Traditional Chinese Medicine (TCM). Detecting signal or applying pressure at the wrong location can seriously affect the measurement of pulse waves and result in misdiagnosis. In this paper, we propose an effective and high accuracy regression model using 3-dimensional convolution neural networks (CNN) processing near-infrared picture sequences to locate radial artery upon radius at the wrist. Comparing with early studies using 2-dimensional models, 3D CNN introduces temporal features with the third dimension to leverage pulsation rhythms. The model had achieved superior performance accuracy as 0.87 within 50 pixels at picture resolution of 2048*1088. Model visualization shows that the additional dimension of the temporal convolution highlights dynamic changes within image sequences. This study presents the great potential of our constructed model to be applied in real wrist palpation location scenarios to bring the key convenience for pulse diagnosis.

Abstract
Background: Overuse of electronic products and decrease in levels of physical activity may lead to an increased incidence of spinal health problems in college students. This study aims to 1) identify the incidence of spinal health problems in college students, 2) to explore the key postural factors in development of spinal musculoskeletal dysfunction and scoliosis, and 3) to clarify new strategies for early identification and prevention of scoliosis. Methods: A cross-sectional screening by static posture assessment, selective functional movement assessment (SFMA) and Adam's Forward Bend Test, was conducted to 306 college students from October to December 2019. Descriptive analysis, Spearman correlation analysis and binomial logistic regression analysis were performed on the collected data.Results: Static postural assessment was completed among 306 college students, 53% of students’ external auditory meatus and acromioclavicular joint were not in the same gravitational line, 45% had forward-head posture, 42% had uneven shoulders. When performing SFMA, we found spinal musculoskeletal dysfunctions, including abnormalities of multi-segment spine flexion (32%), cervical rotation to right (18%), cervical rotation to left (16%), etc. In Adam's Forward Bend Test, 10.78% had a positive result, which suggested structural or functional scoliosis. Correlation analysis showed that the top three postural factors related to spinal musculoskeletal dysfunctions included uneven shoulders, forward-head, position of thorax and pelvis rotated. And top three postural factors related to scoliosis were spinous processes line deviating from midline, winged scapula and head rotation off midline. Logistic regression analysis displayed that there are two high risk factors for scoliosis, including external auditory meatus and acromioclavicular joint not in the same vertical line (OR = 6.314), and deviation of spinous processes line (OR = 12.743). Conclusions: Poor posture, spinal musculoskeletal dysfunction and scoliosis affect a significant proportion of college students. While their spinal musculoskeletal dysfunction and scoliosis are closely related to poor posture.

Abstract
Objective: Our study aimed to report the clinical features of ATTR-PN with TTR p.Ala117Ser mutation in mainland China. Methods: Thirteen patients from 13 different families diagnosed with p.Ala117Ser ATTR-PN were identified from three centres. Clinical and laboratory data were retrospectively retrieved for analysis. Results: The male/female ratio was 11:2. All patients showed late onset, with the age of onset at 57.8 ± 5.8 years. The initial symptom was numbness of the lower or upper extremities in 9 patients (69.2%). Paraesthesia was present in all patients. Eleven patients (84.6%) had autonomic dysfunction. Cardiac, renal, hepatic, and ocular dysfunctions were noted in 8 (61.5%), 1 (7.7%), 2 (15.4%), and 3 (23.1%) patients, respectively. Nerve conduction studies have shown axonal-type sensorimotor polyneuropathy. The decline in sensory nerve action potentials was more noticeable than in compound muscle action potentials. The nerve damage present in the lower limbs was more severe than that in the upper limbs. Nerve biopsy revealed positive Congo red staining in 7/10 patients (70%). Conclusion: Our study is the largest population report on this rare p.Ala117Ser mutation in mainland China.

Abstract
Background and aimThe aim of this study is to assess the cortical bone thickness and inter-radicular distance between posterior maxillary teeth using Cone Beam Computed Tomography (CBCT).Methods and materialCone beam computed tomography records of 35 patients (70 quadrants) from maxilla were evaluated. The images were analyzed using NNT viewer Software (Version 23). The measurements were made on axial sections at 2, 4, 6 and 8 mm from the CEJ. The optimal sites were defined in terms of (a) mesiodistal palatal or buccal inter-radicular distance, (b) alveolar cortical bone thickness and (c) palatal or buccal safe depth of bone for mini-screw insertion. Descriptive statistics, paired T-test and repeated measure ANOVA were used to analyze the data.ResultsThe mean buccal inter-radicular distance was lowest between first and second molar (2.44 mm) and highest between first and second premolar (3.28 mm). The mean palatal inter-radicular distance was lowest between first and second premolar (3.64 mm) and highest between second premolar and first molar (5.30 mm).The mean buccal safe depth was lowest between canine and first premolar (1.96 mm) and highest between first and second molar (2.61 mm). The mean palatal safe depth was lowest between second premolar and first molar (3.35 mm) and highest between first and second molar (3.56 mm). The thinnest and thickest buccal cortical thickness was detected on canine and first molar (1.04 mm) and on the second premolar and second molar (1.56 mm). ConclusionThe quantity and quality of the maxillary alveolar process is an important factor to decide where to insert the orthodontic mini screws, necessitating careful preoperative evaluation.

Published: October 2021

Abstract
Background
Falls contribute to disability and burden of care among older adults. Studies of fall-related impacts on quality of life (QOL) are warranted for future prevention interventions.
Methods
Fall-related data were collected from adults aged 70 years and above using questionnaire interviews in the 1996 and 1999 surveys at Hunei community in southern Taiwan. Their QOL was measured using the Short Form 36 Health Survey (SF-36) and World Health Organization Quality of Life questionnaire (WHOQOL-BREF) in the 1999 follow-up only. The bilateral relationship among fall category, selected covariates (i.e., age, sex, number of difficulties in performing activities of daily living (ADLs) or instrumental ADLs, number of comorbidities, Geriatric Depression Scale (GDS) scores, Mini-Mental Stated Examination (MMSE) scores, fear of falling, and Physical Activity Scale for the Elderly (PASE) scores), and mean QOL scores were investigated. Hierarchical linear regression models were tested to examine the associations between fall frequency and QOL with sequential entry of explanatory variables. The final models were established by substituting fall category for fall frequency.
Results
Fall category was significantly associated with physical-related subscale scores, except body pain. Almost every QOL score revealed a negative association with the number of comorbidities, GDS scores, and fear of falling; however, a positive association with MMSE and PASE scores was observed.
Conclusions
Future prevention interventions should target common risk factors of both QOL and falls among older people, including control of comorbidities, depressive symptoms, cognitive impairment, and inactivity.

Authors: Zhao Dewan , Ni Jing , Sun Xiuli 
Published: October 2021

Abstract
Background: Sweet syndrome with both histiocytoid pathology and giant cellulitis-like lesion feature is extremely rare and has only been reported once. Our case is different from the previous report because the cutaneous lesion was caused by local invasive irritation, which made it much more difficult to distinguish from cellulitis.Case presentation: A 52-year-old male was diagnosed with myelodysplastic syndrome with multilineage dysplasia (MDS-MLD) associated with myelofibrosis (MDS-F) as well as angioneurotic edema of the tongue and floor of the mouth. Seven days after sternal aspiration, a cellulitis-like lesion was formed at the puncture site. Since he had neutropenia, history of glucocorticoid use and didn't keep the site dry and clean after aspiration, cellulitis was diagnosed, followed by broad-spectrum antibiotics and debridement. However, the lesion continued to expand, associated with blisters formation, accompanied by chills and fever. Blood cultures and blister smears didn't detect any pathogens. Biopsy of the lesion was performed and histiocytoid Sweet syndrome was diagnosed. He received prednisone treatment, and the fever relieved within 24 hours and the cutaneous lesion resolved within one week. He has had no recurrence during two-month follow-up.Conclusions: This case can provide help for timely diagnosis and treatment and a reference for further summarizing the characteristics of this rare variant.

Abstract
Limosilactobacillus pontis is a species of lactic acid bacteria (LAB) found in fermented milk, sourdough and broiler chickens gastrointestinal tract and so on. However, the evolutionary strategies and genomic characteristics of the species remain unknown, which limits its application. In this study, whole genome sequencing was combined with a comparative genomic approach to investigate genomic characteristics and evolutionary strategies of L. pontis; this includes three published genomic sequences and two strains isolated from fermented milk in Inner Mongolia, China. The mean genome size and GC content of L. pontis was 1.70 Mb and 53.06%, respectively. Within the LAB L. pontis has a high GC content. The phylogenetic tree based on 1,281 core genomes showed that strains from the same sources aggregated together in clusters. Genome information, average nucleotide identity values, and phylogenetic relationships amongst L. pontis from different sources indicated that strains have potential niche adaptability. Functional genomic aspects, GT2 and GT4 (glycosyltransferases, GTs) involved in the synthesis of cellulose and sucrose were the family with the largest number of carbohydrate enzymes in L. pontis, particularly strains isolated from fermented milk. It is worth mentioning that the ability of L. pontis to produce bacteriocin may increase its application potential. This study provides new insight into the genetic characteristics and potential niche adaptations of L. pontis.

Abstract
This paper investigates analytically the effect of dissimilarity of mass flow rate \({\dot{(m}}_{f})\) and number of collectors (N) on exergo-enviro-economic parameters for solar still of single slope type integrated with N similar photovoltaic thermal flat plate collectors having series connection (NPVTFPC-SS) keeping water depth as 0.14 m. All four kinds of weather conditions for New Delhi have been taken for the computation of different parameters. All relevant equations obtained using energy balance equations for all components of the system have been fed to computer code inscribed in MATLAB-2015a for computing different parameters. The computation of different relevant parameters has been performed for various values of \({\dot{m}}_{f}\) and N while keeping water depth as constant to know the effect of variation of \({\dot{m}}_{f}\) and N on exergo-enviro-economic parameters for NPVTFPC-SS. It has been concluded that the value of carbon credit earned, enviroeconomic and exegoeconomic parameters and productivity diminishes with the enhancement in \({\dot{m}}_{f}\) at given N. The optimum value of N for given value of \({\dot{m}}_{f}\) has been found to be 10 from exergoeconomic parameter viewpoint and 6 from productivity viewpoint.

Published: October 2021

Abstract
Introduction

: Surgery for cerebellar hemangioblastoma can be challenging because of the tumor’s location in the posterior fossa and its inherent nature of hypervascularity.
Methods

We reviewed a total of seven consecutive patients who received microsurgery adjunction with indocyanine green (ICG) videoangiography.
Results

Our study included four female and three male patients. All tumors were located in the cerebellum. We used ICG videoangiography for the purposes of identifying a small tumor inside the cyst in one case, for defining feeding arteries and draining veins in three cases, for confirming residual tumor in the resection cavity in two cases, and for assessment of tumor shunt flow in one case of extremely hypervascular hemangioblastoma. Median blood loss during surgery was 100 mL, and total resection was achieved in all cases with no complications. No adverse effects of ICG videoangiography were observed.
Conclusions

ICG videoangiography is a very useful adjunctive tool for cerebellar hemangioblastoma surgery.

Published: October 2021

Abstract
While measurement of QT prolongation in electrocardiogram (ECG) is important to clinical applications, but it is quite difficult to evaluate the performance of QT measurement algorithms using clinical ECGs because the real values of the Q-point and T-end point changes are usually unknown and is difficult to detect.This research paper deals with the Abnormality Detection and its analysis using MATLAB tool software. In this paper, abnormity which is in concern is known as QT prolongation. Due to prolongation or extention of QT interval in the ECG graph obtained from abnormal patient, known as QT syndrome is caused.For the analysis purpose, Large number of data has been taken from QT database and MIT-BIH database. Some of the other useful data were also obtained from other useful sources such as ECG wave maven. In this paper, we have dealt only with the detection of QT interval and its detection. A MATLAB algorithm has been generated which in turns detect the Q-wave and T-end point corresponding to its input samples.This algorithm is designed and analyzed with more than 100 samples taken from the various data base sources. It detects onset of the Q-wave and T-end point which in turn is used to calculate QT interval of the analyzed ECG sample.

Abstract
Background: Evaluating malaria control strategies for pregnant women is essential. The objective of this study was to determine the factors influencing the frequency of prenatal consultations (PNC), the adherence to intermittent preventive treatment with sulfadoxine-pyrimethamine (IPT-SP) and its impact on the health of parturient women and their newborn babies living in semi-urban and rural areas of southeastern Gabon.Methods: This transversal study was performed at the Centre Hospitalier Régional Paul Moukambi de Koula-Moutou (CHRPMK). Information regarding age, frequency of prenatal consultations, obstetric history, use of malaria control measures, use of IPT-SP, malaria diagnostic of parturient women and their newborns, were collected with a questionnaire and from birth registers from January 1st 2018 to December 31st 2019.Results: In total, 2174 parturient women were included in the study. The mean age was 26.2 ± 6.99 years and 81.4% of parturient women attended at least four CPN. The proper attendance of PNC (at least 4 prenatal consultations) was linked with age (p< 0.001) and profession (aOR= 1.72 [1.27 - 2.37]; p< 0.001). The coverage rate of IPT-SP was 90% with a good adherence rate (at least three doses of IPT-SP) of 58.87%. The good adherence rate to IPT-SP was linked to profession (aOR= 1.65 [1.20 - 2.29]; p< 0.01) and age (p< 0.001). The mean weight of newborns was higher for babies whose mothers had received three doses of IPT-SP (p< 0,001) but the APGAR score was not influenced by the use of IPT-SP by the mother (p= 0.47). The prevalence of plasmodial infection was 3.10% (IC95%= [1.21 - 5]) and Plasmodium falciparum was responsible for 100% of infections. The prevalence of plasmodial infection was the same for all age groups (p> 0.06). No link was found between plasmodial infection, gravidity (p> 0.06) and domestic control measures (p≥ 0.05). A low birth weight was statistically linked to the mother’s plasmodial infection (OR= 9.42 [2.55 – 34.75]; p< 0.01). Furthermore, plasmodial infection was statistically linked to premature birth (OR= 69.25 [8.52 – 562.69]; p< 0.001).Conclusions: We observed a good attendance of women to prenatal counselling services in southeastern Gabon, though the adherence of IPT-SP is insufficient.

Abstract
Background:

Burnout among physicians is a serious concern that cultivates its seeds during their education and matures in their daily practicing life. Lebanese physicians were particularly at high risk of burnout since they confronted a mixture of overlapping crises.
Objectives:

This study aimed to assess the prevalence of burnout among Lebanese physicians, to investigate its associated factors and to explore the combined effects of the pandemic and the economic crisis on burnout.
Methods:

A web-based cross-sectional study was conducted among Lebanese physicians over December 2020 using a snowball sampling technique. Self-reported data were collected electronically through an anonymous questionnaire that included information on socio-demographic characteristics, work-related variables, and 4 scales: fear of COVID-19, threat perception, InCharge Financial Distress/Financial Well-Being, and the Copenhagen burnout inventory (CBI). CBI scale cut-off score of 50 was used to evaluate the prevalence of burnout. Multivariable linear regression analyses were carried out to identify the factors associated with burnout.
Results:

A total of 398 physicians participated in the study. The majority of them were male (52.8%), married (60.1%), and aged between 40 and 49 years (43.2%). Burnout hits 90.7% of the Lebanese physicians where personal, work-related, and client-related burnout were detected among 80.4%, 75.63%, and 69.6% of them respectively. A strong association was found between the higher level of burnout and female gender, younger age, being single, having a dependent child, living with an elderly or having a family member with comorbidities, and insufficient sleeping hours. Physicians’ specialties, working in a public health facility, limited years of professional experience, lack of previous experience in pandemic and extensive working hours were also associated with increased burnout. Furthermore, low income, working in the frontline, higher threat perception, and fear of COVID-19 were contributing to higher burnout. However, financial wellbeing, altruism, having good health, and previous history of COVID-19 were significantly associated to lower burnout. The combined effect of threat perception and financial hardship significantly increased the level of burnout.
Conclusion:

The huge burnout level among Lebanese physicians raises alarm about the seriousness of the current situation and urges the health authorities to take prompt action to enhance the physicians’ wellbeing.

Published: October 2021

Abstract
Aims: Soil fungi are crucial drivers of log decomposition in forest ecosystems. The objective of this study was thus to assess the conservation roles of decaying logs on soil fungi.Methods: Five classes of decaying Minjiang fir (Abies faxoniana) logs were incubated on the forest floor in a subalpine coniferous forest on the eastern Qinghai-Tibet Plateau, China, and the fungal communities compositions of the soil under decaying logs were assessed using high-throughput sequencing. Results: A total of 4321 operational taxonomic units (OTUs) were detected by Illumina MiSeq sequencing analysis. Basidiomycota and Ascomycota were dominant phyla regardless of log decay classes. With the log decomposition, the proportion of arbuscular mycorrhiza, wood saprotroph and saprotroph increased, but that of ectomycorrhiza decreased. Moreover, the diversity of soil fungal communities also increased along the decomposing process of logs. The decaying logs significantly altered soil fungal community composition by affecting biochemical properties (e.g. pH and concentrations of microbial biomass nitrogen and total phosphorus) and environmental factors (e.g. soil water content). Conclusion: Different decay classes of logs favor special fungal species, implying that the logs conservation with different decay classes in the forest ecosystem is of great significance for improving the diversity of soil fungi.
