Published: October 2021

Based on morphological and phylogenetic studies, Selaginella qingchengshanensis, a new species in S. sect. Heterostachys from Sichuan, China is described and illustrated. Morphologically, the new species is similar to S. amblyphylla, but has sterile leaves with denticulate to slightly ciliate margins, dorsal leaves with long arista (as long as leaves) perpendicular to stems and branches in living plants, and axillary leaves triangular-ovate or broadly ovate. Molecular analyses based on ITS+5.8S and rbcL data also support it as a distinct species.

Objective: The coronavirus disease 2019 (COVID-19) has become a global pandemic. Timely and effective predictors of survival and death rates are crucial for improving the management of COVID-19 patients. In this study, we evaluated the predictors of mortality based on the demographics, comorbidities, clinical characteristics, laboratory findings, and vital signs of 500 patients with COVID-19 admitted at Imam Khomeini Hospital Complex, the biggest hospital in Tehran, Iran. Methods: Five hundred hospitalized laboratory-confirmed COVID-19 patients were included in this study. Subsequently, electronic medical records, including patient demographics, clinical manifestation, comorbidities, and laboratory test results were collected and analyzed. They were divided into two groups: expired and discharged. Demographics, clinical, and laboratory data were compared among the two groups. The related factors with death in the patients were determined using univariate and multivariate logistic regression approaches. Results: Among the 500 hospitalized patients, most patients were male (66.4% versus 33.6%). The expired group had more patients ⩾70 years of age compared with the discharged group (32.9% versus 16.3%, respectively). Almost 66% of the expired patients were hospitalized for ⩾5 days which was higher than the discharge group (26.9%). Patients with a history of opium use in the expired group were significantly higher compared to the discharged group (14.8% versus 8.6%, p = 0.04) as well as a history of cancer (15.5% versus 4.7%, p < 0.001). Out of the 500 patients with COVID-19, four patients (2.6%) were HIV positive, all of whom expired. Dyspnea (76.4%), fever (56.6%), myalgia (59.9%), and dry cough (67%) were the most common chief complaints of hospitalized patients. Age ⩾70 years (adjusted odds ratio = 2.49; 95% confidence interval, 1.02–6.04), being female (adjusted odds ratio = 2.06; 95% confidence interval, 1.25–3.41), days of hospitalization (adjusted odds ratio = 5.73; 95% confidence interval, 3.49–9.41), and having cancer (adjusted odds ratio = 3.23; 95% confidence interval, 1.42–7.39) were identified as independent predictors of mortality among COVID-19 patients. Conclusion: Discharged and expired COVID-19 patients had distinct clinical and laboratory characteristics, which were separated by principal component analysis. The mortality risk factors for severe patients identified in this study using a multivariate logistic regression model included elderly age (⩾70 years), being female, days of hospitalization, and having cancer.

Introduction: To investigate antitumor activity and mechanism of flavonoids from Alpinia officinarum Hance against gastric cancer. Methods: Transplanted mouse fore-stomach carcinoma (MFC) tumor mice were divided into six groups: control group, model group, low dose (20 mg/kg), middle dose (40 mg/kg), and high dose (80 mg/kg) groups of TFAO and 5-Fu group. Mice were treated with TFAO or 5-Fu for 14 days, except those of control and model group. Tumor inhibitory rate, spleen, and thymus index were calculated. Contents of proliferating cell nuclear antigen, MMP-9, vascular endothelial growth factor, IL-1β, IL-6, and IL-17 in serum were detected. Effect of galangin on BGC-823 cell growth was detected. Cell apoptosis and cell cycle distribution were measured. Enzyme activity of Caspase-3, Caspase-8, and Caspase-9 was detected. Western blot was used to detect STAT3, Bcl-2, Bax, Caspase-3, Caspase-8, Caspase-9, CyclinB1, and CyclinD1 protein expression in BGC-823 cell. Results: Compared with model group, tumor weight of mice decreased significantly ( p < .01) in 5-Fu group, low dose, middle dose, and high dose group of TFAO; thymus index of mice decreased significantly ( p < .05) in 5-Fu group; and spleen index decreased significantly ( p < .05) in low dose and middle dose groups of TFAO. Compared with model group, levels of PCNA, MMP-9, IL-1β, and IL-6 in serum of mice decreased obviously ( p < .01) in all administration groups; levels of VEGF in serum of mice decreased obviously ( p < .01) in low dose and high dose group of TFAO and 5-Fu group; and levels of IL-17 in serum of mice decreased significantly ( p < .01) in low-dose and middle-dose groups of TFAO and 5-Fu group. Galangin could inhibit BGC-823 cell growth; accelerate apoptosis; block cell cycle; increase cell Caspase-3, Caspase-8, and Caspase-9 enzyme activity; upregulate expression of Caspase-3, Caspase-8, Caspase-9, and Bax; and downregulate expression of STAT3, CyclinB1, CyclinD1, and Bcl-2 protein. Conclusion: Flavonoids from A. officinarum showed antitumor activity in gastric cancer. Mechanisms may be associated with inhibition of tumor angiogenesis, tumor cell proliferation, and cancer-associated inflammation.

Published: October 2021

Abstract
Background
To evaluate the effects of pretreatment for dry eye disease (DED) on the accuracy of intraocular lens (IOL) power calculation.

Methods
Patients who underwent uneventful cataract surgery were included in the study. IOL power was determined using the SRK/T and Barrett Universal II (Barrett) formulas. The patients were divided into non-pretreatment and pretreatment groups, and those in the pretreatment group were treated with topical 0.5% loteprednol etabonate and 0.05% cyclosporin A for 2 weeks prior to cataract surgery. Ocular biometry was performed in all groups within 2 days before surgery. The mean prediction error, mean absolute error (MAE), and proportions of refractive surprise were compared between the non-pretreatment and pretreatment groups at 1 month postoperatively. Refractive surprise was defined as MAE ≥ 0.75D.

Results
In a total of 105 patients, 52 (52 eyes) were in the non-pretreatment group and 53 (53 eyes) in the pretreatment group. The MAE was 0.42 ± 0.33, 0.38 ± 0.34 (SRK/T, Barrett) and 0.23 ± 0.19, 0.24 ± 0.19 in the non-pretreatment and pretreatment groups, respectively (p < 0.001/=0.008). The number of refractive surprises was also significantly lower in the pretreatment group. [non-pretreatment/pretreatment: 9/2 (SRK/T); 8/1 (Barrett); p = 0.024/0.016]. Pretreatment of DED was related to a reduction in postoperative refractive surprise. [SRK/T/Barrett: OR = 0.18/0.17 (95% CI: 0.05–0.71/0.05–0.60), p = 0.014/0.006].

Conclusions
The accuracy of IOL power prediction can be increased by actively treating DED prior to cataract surgery.
The knowledge, attitudes and beliefs of midwives on the vaccination coverage rates in Perth’s Aboriginal children
Authors: Carman Rebecca , Andrew Lesley , Devine Amanda 
Published: October 2021

Abstract
Background
Midwives are well placed to promote vaccination awareness throughout a women’s pregnancy and strengthen childhood vaccination demand following hospital discharge. In Perth, Western Australia, Aboriginal children experience some of the lowest vaccination coverage rates across the nation. To identify factors preventing greater vaccination uptake amongst the target population, a theory-based study was conducted with midwives across two Perth maternity hospitals to explore behavioural attributes, knowledge, attitudes and beliefs surrounding vaccination provision and the vaccines administered to Aboriginal children.

Methods
A purpose-designed questionnaire was distributed to midwives working in two Perth public maternity hospitals. The proximal constructs of The Theory of Planned Behavior were used to frame the questionnaire to enable the barriers to greater vaccination coverage to be identified and behaviourally situated. Descriptive statistics described the demographics of the study sample. Chi-square and the Fisher’s exact test were used to identify associations between midwife characteristics and awareness of the coverage rates. Significance was set at α = 0.05.

Results
Of the 58 midwives who completed the study questionnaire, 77.2% were unaware of the sub-optimal vaccination coverage in Perth’s Aboriginal children. Level of education (p = 0.53) and years worked as a practising midwife (p = 0.47) were not found to be associated with an awareness of the coverage rates. Approximately, 50% of midwives reported some concern over the efficacy of childhood vaccines, 44.4% did not feel confident with their knowledge of vaccines, while 33.3% do not routinely discuss childhood vaccinations with parents prior to hospital discharge.

Conclusions
Key findings in the study identified that a range of educational, leadership and system-based issues are affecting midwives’ capacity to play a more substantial role in influencing vaccination coverage in Perth’s Aboriginal children.
Spatial analysis and evaluation of medical resource allocation in China based on geographic big data
Authors: Wan Sida , Chen Yanming , Xiao Yijia , Zhao Qiqi , Li Manchun , Wu Shuqi 
Published: October 2021

Abstract
Background
Spatial allocation of medical resources is closely related to people’s health. Thus, it is important to evaluate the abundance of medical resources regionally and explore the spatial heterogeneity of medical resource allocation.

Methods
Using medical geographic big data, this study analyzed 369 Chinese cities and constructed a medical resource evaluation model based on the grading of medical institutions using the Delphi method. It evaluated China’s medical resources at three levels (economic sectors, economic zones, and provinces) and discussed their spatial clustering patterns. Geographically weighted regression was used to explore the correlations between the evaluation results and population and gross domestic product (GDP).

Results
The spatial heterogeneity of medical resource allocation in China was significant, and the following general regularities were observed: 1) The abundance and balance of medical resources were typically better in the east than in the west, and in coastal areas compared to inland ones. 2) The average primacy ratio of medical resources in Chinese cities by province was 2.30. The spatial distribution of medical resources in the provinces was unbalanced, showing high concentrations in the primate cities. 3) The allocation of medical resources at the provincial level in China was summarized as following a single-growth pole pattern supplemented by bipolar circular allocation and balanced allocation patterns. The agglomeration patterns of medical resources in typical cities were categorized into single-center and balanced development patterns. GDP was highly correlated to the medical evaluation results, while demographic factors showed, low correlations. Large cities and their surrounding areas exhibited obvious response characteristics.

Conclusions
These findings provide policy-relevant guidance for improving the spatial imbalance of medical resources, strengthening regional public health systems, and promoting government coordination efforts for medical resource allocation at different levels to improve the overall functioning of the medical and health service system and bolster its balanced and synergistic development.
Identification of Mycoplasma species and related organisms from ruminants in England and Wales during 2005–2019
Authors: Deeney Alannah S. , Collins Rachael , Ridley Anne M. 
Published: October 2021

AbstractBackgroundMycoplasmaspecies have been associated with economically important diseases affecting ruminants worldwide and include contagious bovine pleuropneumonia (CBPP), contagious caprine pleuropneumonia (CCPP) and contagious agalactia, listed by the World Organisation for Animal Health (OIE). The Mycoplasma Team at the Animal and Plant Health Agency provides an identification service forMycoplasmaandUreaplasmaspecies of veterinary importance to the United Kingdom (UK), supporting the detection of new and emerging pathogens, as well as contributing to the surveillance of endemic, and the OIE listed diseases exotic to the UK.Mycoplasmaand otherMollicutesspecies were identified from diagnostic samples from farmed ruminants in England and Wales using a combination of culture and 16S rRNA gene-based PCR-denaturing gradient gel electrophoresis, submitted between 2005 and 2019.ResultsA total of 5578 mollicutes identifications, which include mycoplasmas and the related acholeoplasmas and ureaplasmas, were made from farmed ruminant animals during the study period. Throughout the study period, the pathogenMycoplasma boviswas consistently the most frequently identified species, accounting for 1411 (32%) of 4447 molecular identifications in cattle, primarily detected in the lungs of pneumonic calves, followed by joints and milk of cattle showing signs of arthritis and mastitis, respectively.M. bovirhinis,M. alkalescens,M. dispar,M. argininiandUreaplasma diversum, were also common. Mixed species, principallyM. boviswithM. alkalescens, M. argininiorM. bovirhiniswere also prevalent, particularly from respiratory samples. The non-cultivable blood-borne haemoplasmasCandidatus‘Mycoplasma haemobos’ andMycoplasma wenyoniiwere identified from cattle, with the latter species most often associated with milk-drop.M. ovipneumoniaewas the predominant species identified from sheep and goats experiencing respiratory disease, whileM. conjunctivaepreponderated in ocular samples. The UK remains free of the ruminant mycoplasmas listed by OIE.ConclusionsThe continued high prevalence ofM. bovisidentifications confirms its ongoing dominance and importance as a significant pathogen of cattle in England and Wales, particularly in association with respiratory disease.M. ovipneumoniaehas seen a general increase in prevalence in recent years, notably in coughing lambs and should therefore be considered as a primary differential diagnosis of respiratory disease in small ruminants.
GLP-1 receptor agonists vs. SGLT-2 inhibitors: the gap seems to be leveling off
Authors: Giugliano Dario , Scappaticcio Lorenzo , Longo Miriam , Bellastella Giuseppe , Esposito Katherine 
Published: October 2021

AbstractCardiovascular disease (CVD) remains the leading cause of death in patients with type 2 diabetes (T2D). Older age, prior heart failure (HF) and CV events, peripheral artery disease, and kidney complications can identify a subgroup of patients with T2D at high risk of mortality who are likely to achieve the greatest benefit from newer glucose-lowering agents. Both glucagon-like peptide-1 receptor agonists (GLP-1RA) and sodium-glucose cotransporter-2 (SGLT-2) inhibitors can reduce CV risk in patients with T2D, and both are recommended by the American Diabetes Association to reduce the risk of major cardiovascular events (MACE). The magnitude of the benefits of GLP-1RA and SGLT-2 inhibitors on MACE are similar, ranging from 12 to 14% reduction of risk, but only GLP-1RA may reduce the risk of stroke. The most striking difference between the two classes of drugs relates to the amelioration on hospitalization for HF, as the benefit of SGLT-2 inhibitors surpass by threefold that obtained with GLP-1RA. Despite this, GLP-1RA also exert a significant benefit on HF which suggest their use when SGLT-2 inhibitors are contraindicated or not tolerated. The difference between the two classes is less impressive for the kidney outcome. Overall, the results of CVOTs published so far seems to suggest that the gap between the cardiorenal benefits of SGLT-2 and GLP-1RA is narrowing.
EQ-5D-5L in Schizophrenia: differences between patients and nurses’ reports
Authors: Purba Fredrick Dermawan , Anggriani Yusi , Murtini Tri 
Published: October 2021

Abstract
Purpose
To examine the differences between patient-reports and proxy-reports by nurses of EQ-5D-5L responses among patients with schizophrenia.

Methods
This study was conducted in June–September 2019 in Duren Sawit Regional Public Hospital in Jakarta, Indonesia. The self-report data were obtained by interviewing the patients and the proxy-report data were obtained from the psychiatric nurses. The patients’ Positive and Negative Syndrome Scale (PANSS) scores were obtained from their medical records. The data were collected in two time points: (1) when the patients moved from the acute to the quiet rooms (first-test) and (2) when they were discharged from the hospital (second-test). The self and proxy report scores were analysed by the Wilcoxon matched-pairs signed-ranks test and their relationship with the PANSS scores using Spearman's rank correlation coefficient.

Results
There were 206 patients in the final sample. The majority are male (56.8%) with a mean age of 37.5 years (SD = 12.05). Significant differences between the two reports were found in three domains (i.e., self-care, usual activities, and pain/discomfort) in the first-test and two domains (i.e., usual activities and pain/discomfort) in the second-test. Concerning the relationship with the PANSS scores, only three significant correlations were found, all in the proxy-version and in the second-test: mobility (r = 0.139), anxiety/depression (r = 0.2523), and utility scores (r = − 0.176).

Conclusions
The poor-to-fair agreement between patients and nurses reports and the poor correlation with the PANSS scores suggested that it is difficult to decide which report best represents the patients’ health status.

Abstract
Background
Despite considerable policy actions at the national and hospital levels, rates of breastfeeding in the Middle East and North Africa (MENA) region remain below the global average. There is a need to explore the modifiable factors of breastfeeding such as maternal breastfeeding self-efficacy (BSE), support, and mental health among women in this region to guide interventions in the United Arab Emirates (UAE). The aim of this study was to examine the maternal predictors of any and exclusive breastfeeding in a cohort of Emirati and expatriate women residing in the UAE with a specific focus on modifiable factors.

Methods
Using a prospective cohort design, Emirati and expatriate women were recruited in the immediate postpartum period (N = 374) and followed at three and 6 months postpartum between February 2018 and July 2019. Questionnaires with validated tools were used to collect information on sociodemographic characteristics, breastfeeding practices, BSE, postnatal depression, and anxiety. The main outcomes in the study were Any Breastfeeding and exclusivity practices, which were assessed at three and 6 months postpartum by asking the mother about her breastfeeding behaviour during the past 7 days. Multilevel, multivariate logistic regression was used to estimate the association of different variables with breastfeeding outcomes.

Results
Almost all women reported initiating breastfeeding during their stay at the hospital (n = 357), while only 263 (70.3%) initiated breastfeeding within the first hour of delivery. At 6 months postpartum, 301 (81.5%) women continued to breastfeed of whom 100 (26.7%) were doing so exclusively. Older mothers who initiated breastfeeding within 1 h of birth and were satisfied with the breastfeeding support they received from family and friends had significantly greater odds of any breastfeeding at 6 months. Whereas a clinically significant Edinburgh Postnatal Depression Scale (EPDS) score, low BSE score as well as employment outside the home were associated with significantly lower odds of exclusive breastfeeding and any breastfeeding at 6 months postpartum.

Conclusion
This study highlights the need to develop effective education strategies and support programs targeting these modifiable variables to improve breastfeeding outcomes among women in the UAE.
Analysis of canopy phenology in man-made forests using near-earth remote sensing
Authors: Guan Peng , Zheng Yili , Lei Guannan 
Published: October 2021

Abstract
Background
Forest canopies are highly sensitive to their growth, health, and climate change. The study aims to obtain time sequence images in mix foresters using a near-earth remote sensing method to track the seasonal variation in the color index and select the optimal color index. Three different regions of interest (RIOs) were defined and six color indexes (GRVI, HUE, GGR, RCC, GCC, and GEI) were calculated to analyze the microenvironment difference. The key phenological phase was identified using the double logistic model and the derivative method, and the phenology forecast of color indexes was performed based on the long short-term memory (LSTM) model.

Results
The results showed that the same color index in different RIOs and different color indexes in the same RIO present a slight difference in the days of growth and the days corresponding to the peak value, exhibiting different phenological phases; the mean squared error (MSE), root mean squared error (RMSE), mean absolute error (MAE), and mean absolute percentage error (MAPE) of the LSTM model was 0.0016, 0.0405, 0.0334, and 12.55%, respectively, indicating that this model has a good forecast effect.

Conclusions
In different areas of the same forest, differences in the micro-ecological environment in the canopies were prevalent, with their internal growth mechanism being affected by different cultivation ways and the external environment. Besides, the optimal color index also varies with species in phenological response, that is, different color indexes are used for different forests. With the data of color indexes as the training set and forecast set, the feasibility of the LSTM model in phenology forecast is verified.
