Introduction: Diabetes mellitus (DM) is one of the most common diseases in the world and diabetic foot ulcer (DFU) is one of the main causes of mortality and morbidity. This study was done for the evaluation of prognostic risk factors in hospitalized patients with DFU.
Material and Methods: In this cross-sectional study, the records of all patients with DFU referred to Sayyad Shirazi Hospital in Gorgan during 2018-2020 were reviewed to determine the demographic characteristics, paraclinical findings, and clinical features. All information of patients was entered into the checklist. Frequency, percentage, mean± standard deviation (SD) were used to describe the data. Chi-square and ANOVA tests were used to investigate the relationship between each. SPSS software version 20 was used for data analysis.
Results: In this study 379 patient with DFU were studied that 54.1% were female. 62.3% of patients were in the age group of 45 -65 years. In these patients, 64.9% had hypertension and 37.7% had cardiovascular disease. 6.8% and 21.2% were smokers and drug addicts, respectively and 17.7% had history of lower limb amputation .76% of patient had grade 2 and 3 Wagner’s DFUs. According to the statistical analysis, there was no significant relationship between insulin treatment, smoking and opium use, and patientchr('39')s age with the final outcome of discharge. The chi-square test showed the relationship between white blood cells (WBCs) erythrocyte sedimentation rate (ESR) level and final outcome.
Conclusion: DFU prognosis may be related to WBC and ESR, grading of DFU, and history of lower limb amputation.

Published: November 2020

Unwanted pregnancy is a world problem. In 2008, there were 208 million pregnancies in the world, and 41% of them were unwanted pregnancy. Cross-national reproductive health studies have indicated that the unwanted pregnancy rates remain substantially high in many developing regions, including in Indonesia (Bearak et al. 2018). Unwanted pregnancies in Indonesia increased from 13.6% in 2012 to 16% in 2015. The high rates of unwanted pregnancies are often linked to the gaps in family planning services such as the effective use of contraceptive methods which is also influenced by family socioeconomic backgrounds such as their occupational status. Using the case study at health clinics of PKBI in East Java, this paper attempts to explore the association or relationship between the risk of unwanted pregnancy among couples of childbearing age (CCA) with their use of contraceptive methods and occupational status. A quantitative method of a case-control research design was applied by using a random sampling technique. The study was 50 women couples of childbearing age (15–45 years), who had unwanted and wanted pregnancies. Simple correlation analysis shows that the association are relatively significant between the occurrence of an unwanted pregnancy with the long-term contraceptive use (p-value = 0.008), and with the employed in occupational status (p-value = 0.027). However, there is no correlation between the unwanted pregnancy occurrence with the short-term contraceptives use (p-value = 0.118). The study concludes that the use of short-term contraceptive methods and the employed status can still affect the risk of unwanted pregnancies, while the effective use of long-term contraceptive method has a vital role in preventing unwanted pregnancies.

Authors: Winarti  , Cahyono Bambang Yudi 
Published: November 2020

Over the last few years, the researchers and practitioners have acknowledged the potential benefits attained from collaborative writing activity which was based on the well- known theories of social constructivist and output hypothesis. Grounding from these theories, this study examined the collaborative writing combined with writing process approach to find out the effect of the task on students' ability in writing an explanation essay and students perception about the task. Two intact classes involving 30 students in each class participated in this study. One class as the experimental group completed the writing task using process writing in pairs while the other class completed the task individually. The students in experimental group were given a questionnaire right after the treatment to pool their views on the task. Post-test by administering the writing test was conducted to see the effect of the treatment. Data analysis revealed that students employing collaborative writing using process writing had better writing ability than students working individually. It was also found that most students felt that they gained many benefits from doing collaborative writing. These findings suggested that collaborative writing combined with process writing can be implemented in EFL writing pedagogy to improve students' writing ability.
HIGHLIGHTS
1. Collaborative writing has the positive effect on the overall writing ability and on each element of writing skill.2. Collaborative writing not only encouraged the students to share the knowledge they had to other members but also it gave them remarkable input they needed in improving thewriting skill.

Published: November 2020

Abstract
Background: The mechanics of double key loop (DKL) was not well defined and this finite element study was designed to explore its force system.Methods: Simplified 3-dimensional finite element model of single and double key loops with archwire between lateral incisor and second premolar was established in Ansys Workbench. Activation in Type-1 (retraction at distal end), Type-2 (retraction at distal key) and Type-3 (Type-2 plus ligation between keys) were simulated. The vertical force, load/deflection ratio and moment/force ratio of stainless steel and TMA loops were calculated and compared.Results: Double key loop generated about 40% force of single key loop. Type-2 loading of DKL showed higher L/D ratio than in Type-1 loading with similar M/F ratio. Type-3 loading of DKL showed the highest M/F ratio with similar L/D ratio as single key loop. The M/F ratio in Type-3 loading increased with the decrease of retraction force. DKL of TMA produced about 40% of force and moment compared to those of SS in all loading types. When activated at equal distance bellow 1mm, the M/F ratio of SS and TMA DKL with equal preactivation angle were almost the same. Conclusion: M/F ratio on anterior teeth increases with preactivation angle and deactivation of DKL. M/F ratio at certain distance of activation depends mainly on preactivation angle instead of wire material. TMA is recommended as substitute of SS in DKL for lower magnitude of force.

Abstract
Background Worldwide, uniformed personnel have been recognized as a population at high risk for sexually transmitted infections because of their high mobility, power differentials and affluence. However, limited studies have been conducted on risky sexual behaviour (RSB) among male uniformed personnel in Nigeria. We conducted this study to determine the prevalence and identify the predictors of RSB among male immigration and correctional personnel in Kano State.Methods We conducted a cross-sectional study among 306 male immigration and correctional personnel using multi-stage sampling technique. A pre-tested self-administered structured questionnaire containing sociodemographic and variables associated with RSB was used for data collection. Indicators of RSB included transactional sexual intercourse, sexual intercourse with casual acquaintances and multiple non-regular sexual partners over the last 12 months. Data were analysed using descriptive statistics, Chi-square test and logistic regression (α=0.05).Results Mean age of the respondents in the immigration and correctional services was 37.9±9.3 and 38.0±8.1 years respectively. Overall prevalence of RSB was 15.1% (9.2% and 20.9% among correctional and immigration workers respectively). The identified predictors of RSB were service group, marital status and attending club house prior to sexual intercourse. The likelihood of RSB was lower among the correctional personnel (aOR=0.38, CI=0.17-0.80) than the immigration officers. Being married is protective of RSB (aOR=0.38, CI=0.18-0.81) while attending club house prior to sexual intercourse predisposes the uniform personnel to RSB (aOR=3.90, CI=1.30-11.68). Conclusions Risky sexual behaviour was highly prevalent among the investigated uniform men but was higher among immigration officers than the correctional personnel.

Published: November 2020

Abstract
Background: Salt tolerance is a key trait in soybean breeding and plant responses to salt stress include physiological and biochemical changes that affect the movement of water across the plasma membrane. In this study, we report the interactions of a set of aquaporins, soybean (Glycine max) plasma membrane-intrinsic proteins (GmPIPs), in response to salt stress. Results: GmPIP1;5 and GmPIP1;6 formed hetero-tetramers with GmPIP2;4, GmPIP2;6, GmPIP2;8, GmPIP2;9, GmPIP2;11, and GmPIP2;13. We detected interactions between GmPIP1;6 and GmPIP1;7, but not between GmPIP1;6 and GmPIP1;5. Furthermore, GmPIP2;9 formed homo-tetramers, and this interaction was strengthened under salt and osmotic stress. Expression analysis indicated complex and unique responses to salt stress depending on the duration of the stress. For example, GmPIP2;8, encoding one of the heteromer-forming PIP proteins, was highly up-regulated under early salt stress.Conclusions: Our study highlights the vital role of hetero- and homo-tetramers, in salt tolerance; and improves understanding of the mechanisms by which soybean aquaporin isoforms respond to abiotic stress.

Abstract
Background: Good dietary quality among pregnant women is critical for maternal and fetal health. Comprehensive assessments of large representative samples are lacking. Methods: Pregnant women were enrolled using a multistage, stratified, random-sampling method in Shanghai. We used a personal food frequency questionnaire and a household condiment weighing method for dietary assessments. Participants’ scores on the China Healthy Diet Index (CHDI) were analyzed to evaluate diet quality.Results: Significant differences in the median daily intake of almost all food types were found across all trimesters, and all food types were found across all residential areas (urban, suburban and rural). Significant differences were found in the median total CHDI scores across trimesters, and on all CHID components, except whole grains, dry beans and tubers, across all residential areas; 13.7% of participants scored below 60 points, indicating “poor” dietary quality. Significant differences in CHDI scores were found across trimesters and residential areas. Participants in early and middle pregnancy had lower scores than those in late pregnancy. Women in urban areas had higher scores than those in suburban and rural areas.Conclusions: Pregnant women living in coastal areas of China suffer from an unbalanced diet of average quality. Pregnant women in the early and middle stages of pregnancy had worse scores than those in the late stage, while suburban and rural women had worse scores than urban women.

Published: November 2020

Abstract
The long-term prognosis of fetus with cardiac rhabdomyoma (CR) depends on the correlation with tuberous sclerosis complex(TSC). Recent years, numerous variations of uncertain significance (VUS) of TSC genes produced by high-throughput sequencing makes counseling challenging, studies until now tend to sidestep the tricky topics. Here, we integrated detailed parental phenotype, echocardiography, neuro MRI and genetic information to conduct a comprehensive evaluation for 61 CR fetuses. As a result, multiple CRs and cerebral lesions appeared in 90% and 80% respectively in fetuses with pathogenic(P)/likely pathogenic(LP) TSC1/TSC2 variation. 85.7% of the live-born with P/LP presented TSC-associated signs. 85.7% VUS without nervous findings had good prognosis. Genetic evidence and cerebral MRI findings are the most sensitive index to assess long-term prognosis, which complement and confirm each other for a TSC diagnosis. 68.9% fetuses with CR could benefit from this multidisciplinary approach, which turned to be potentially clinically actionable with precise clinical/genetic diagnosis or had a foreseeable outcome. Our practice provides a practical and feasible solution for perinatal management and prognostic guidance for fetuses with CR.

Abstract
Background: The outbreak of the novel coronavirus disease (COVID-19) in China has influenced every aspect of life worldwide. Due to the characteristics of dental settings, the risk of cross-infection is high between dental practitioners and patients and dentists may develop severe anxiety about the current pandemic. In addition, the limited provision of services and closure of dental practices raised concerns among dental professionals about the financial consequences of this closure. This study assessed the frequency of dental practice closure in several countries, the factors associated with this closure and whether closure and associated factors differed between private and non-private sectors.Methods: From April to May 2020, an electronic survey was sent to dentists in several countries. The survey assessed professional factors, practice factors and country-level structural factors. Multilevel logistic regression was used to assess the association between practice closure and these factors. Effect modification by type of sector was also assessed. Results: Dentists (n= 3243) participated from 29 countries. The majority (75.9%) reported practice closure with significantly higher percentage in the private sector than the non-private sector. Pandemic- related fears were associated with significantly higher likelihood of practice closure in private (OR= 1.54, 95%CI= 1.24, 1.92) and non-private sectors (OR= 1.38, 95%CI= 1.04, 1.82). Dentists in non-private, governmental sector (OR= 0.54, 95%CI= 0.31, 0.94), those in rural areas (OR= 0.58, 95%CI= 0.42, 0.81) and those in hospitals (overall OR= 0.60, 95%CI= 0.36, 0.99) reported low likelihood of closure. High likelihood of closure was reported by those in academia (OR= 2.13, 95%CI= 1.23, 3.71). More hospital beds at country-level were associated with lower likelihood of closure in the non-private sector (OR= 0.65, 95%CI= 0.46, 0.91). Private sector dentists in high income countries (HICs) reported less closure than in non-HICs (OR= 0.55, 95%= 0.15, 1.93).Conclusions: Most dentists reported practice closure because of COVID-19 with greater impact in the private than non-private sectors. Closure was associated with factors at professional, practice, and country-level.

Published: November 2020

Abstract
Background: Differences in the clinical features and outcomes between syncytial virus-related (RSV-p) and influenza-related pneumonia (Flu-p) are largely unknown. We aimed to compare clinical characteristics and severity between adults with the two conditions . Methods: A total of 127 patients with RSV-p, 693 patients with influenza A-related pneumonia (FluA-p) and 386 patients with influenza B-related pneumonia (FluB-p) were retrospectively reviewed from 2013 through 2019 in five teaching hospitals in China. Results: A multivariate logistic regression model indicated that age ≥ 50 years, cerebrovascular disease, chronic kidney disease, solid malignant tumor, nasal congestion, myalgia, sputum production, respiratory rates ≥ 30 beats/min, lymphocytes < 0.8×109/L and blood albumin < 35 g/L were predictors that differentiated RSV-p from Flu-p. After adjusting for confounders, a multivariate logistic regression analysis confirmed that, relative to RSV-p, FluA-p (OR 2.313 , 95% CI 1.377 - 3.885, p = 0.002) incurred an increased risk for severe outcomes, including invasive ventilation, ICU admission, and 30-day mortality. FluB-p (OR 1.630 , 95% CI 0.958 - 2.741, p = 0.071) was not associated with increased risk. Conclusions: The severity of RSV-p was less than that of FluA-p, but was comparable to FluB-p. Some clinical variables were useful for discriminating RSV-p from Flu-p.

Published: November 2020

Abstract
Background: There were still nonnegligible overlaps between lung inflammatory and malignant lesions in morphologic appearance and enhancement pattern using conventional computed tomography (CT) especially when the lesion size was smaller than 3cm, which made misdiagnosis often happen in clinical practice. The study was to verify whether spectral CT parameters can differentiate solitary lung cancer from solitary inflammatory lesions or not, and to find the correlation between GSI parameters and lesion size. Methods: 102 patients with solitary inflammatory or lung cancer lesions underwent enhanced CT scans with GSI mode. While total of 78 ROIs (region of interest) were finally collected and divided into inflammatory group (group I: ≤3cm, IA; >3cm, IB) and cancer group (group II:≤3cm, IIA; >3cm, IIB) according to their maximum diameter (Dmax). CT values measured on 40keV and 70 keV monochromatic images (HU40kev , HU70kev), effective atomic number (Zeff) , iodine concentration (IC), normalized IC (NIC) and slopes of spectral curve (λ30, λ40) were calculated. Intergroup and intragroup comparisons were made using Mann-Whitney U test, and receiver operating characteristic curve (ROC) analysis were done. Correlation analysis was used to find the relationship between Dmax and GSI parameters. Results: NIC and λ30 under venous phase could distinguish general solitary inflammatory from cancer group. No significant correlation was found between GSI parameters and Dmax in inflammatory group, while negative correlations were found between them in cancer group. The GSI parameters (except HU70kev) of group IIA were significantly higher than those of group IIB. When Dmax was larger than 3cm, there were significant differences between solitary inflammatory group and cancer group in HU40kev, IC, NIC, λ30 and λ40, under both AP and VP, while the AUC for λ30 under VP was largest, and the corresponding sensitivity and specificity were 96.32% and 85.71% respectively. However, only the HU40kev and HU70kev under arterial phase of IIA were significantly higher than those of IA.Conclusions: Most of quantitative parameters of GSI can contribute to the differentiation between solitary lung cancer from solitary inflammatory lesions when Dmax is larger than 3cm, while only few parameters are meaningful when Dmax is smaller than 3cm .
