Abstract
Objective: Scarlet fever is an increasingly serious public health problem that has attracted widespread attention worldwide. In this study, two models were constructed based on time series to predict the number of scarlet fever incidence in Jiangsu province, China
Methods: Two models, ARIMA model and TBATS model, were constructed to predict the number of scarlet fever incidence in Jiangsu province, China, in the first half of 2022 based on the number of scarlet fever incidence from 2013-2021, and root mean square error (RMSE) and mean absolute percentage error (MAPE) were used to select the models and evaluate the performance of the models.
Results: The incidence of scarlet fever in Jiangsu province from 2013 to 2021 was significantly bi-seasonal and trendy, and the best ARIMA model established was ARIMA(1,0,1)(2,1,1)12, with RMSE=92.23 and MAPE=47.48% for the fitting part and RMSE=138.31 and MAPE=79.11 for the prediction part. The best The best TBATS model is TBATS(0.278,{0,0}, -, {<12,5>}) with RMSE=69.85 and MAPE=27.44% for the fitted part. The RMSE of the prediction part=57.11, MAPE=39.52%. The error of TBATS is smaller than that of ARIMA model for both fitting and forecasting.
Conclusion: The TBATS model outperformed the most commonly used SARIMA model in predicting the number of scarlet fever incidence in Jiangsu Province, China, and can be used as a flexible and useful tool in the decision-making process of scarlet fever prevention and control in Jiangsu Province

Abstract
Background
Laparoscopic cholecystectomy (LC) plus laparoscopic common bile duct exploration (LCBDE) is convenient in the treatment of cholelithiasis in combination with choledocholithiasis. It has the advantage of accelerated recovery. This retrospective study aimed to summarize the experience of cholelithiasis and choledocholithiasis treatment via LC plus LCBDE approach in Eastern China.
Methods
Patients diagnosed with cholelithiasis and choledocholithiasis between July 2019 and October 2021 at the Xishan People’s Hospital of Wuxi City were included in the study. During treatment, patients who received LC+LCBDE+primary suturing of the CBD were assigned to the LCBDE-P group, and those who received LC+LCBDE+T-tube drainage of CBD were assigned to the LCBDE-T group. The measurement data were compared between the two groups. P-values < 0.05 indicated statistical significance.
Results
A total number of 88 patients (48 females and 40 males) were divided into two groups: LCBDE-P (n=50) and LCBDE-T (n=38). Multiple linear regression analysis showed that LCBDE-P affected the risk-adjusted hospitalization stay (unstandardized coefficient, -5.352 days; 95% CI: -0.387 to -4.761; P < 0.001) and medical cost (unstandardized coefficient, -0.494 RMB; 95% CI: -0.712 to -0.277; P < 0.001) with significant differences. On the other hand, no significant differences were detected in the operation time, intraoperative hemorrhage, clearance rate of CBD stones, postoperative liver function, and postoperative complications (P > 0.05) between the two groups.
Conclusions
LCBDE is a safe and feasible strategy for the management of cholelithiasis and choledocholithiasis. Compared to LCBDE-T, LCBDE-P decreases hospital stays and medical costs during hospitalization.
Citizen Science Data Reveals Environmental Influence on Sightings of Great White Sharks in Mossel Bay, South Africa

Published: November 2022

Abstract
Whilst previous studies have described the impact of various environmental conditions on behaviour and abundance of great white sharks (GWS), existing knowledge gaps must be addressed in order to turn the tide on their population declines. This study used data collected by a diving tour operator, to investigate how environmental and anthropogenic variables affected the rate of GWS sightings. Observation data were collected by trained crew and volunteers alongside tourists, and combined with externally sourced environmental data. Hurdle modelling identified that the probability of sighting at least one GWS fluctuated seasonally (peaking during winter), but was also correlated with minimum running air temperature, water visibility and the length of time the boat stayed at anchor. The rate GWSs were sighted also rose in winter, and was associated with maximum running air temperature, the arrival time, seal activity, and the wind direction and speed. These findings indicate that environmental conditions directly impacted upon the sighting frequency, but also influenced habitat selection on a fine spatial scale. This study emphasises that collaboration with ecotourism companies could represent a valuable, inexpensive alternative for scientific data collection, as long as powerful statistical methods are used, the influence of human activity is considered and results are interpreted with consideration of the data collection methodology.

Published: November 2022

Abstract
In this paper, we report two structurally characterized, tin(II) and lead(II) compounds supported by sterically encumbered β-diketiminate ligands and are synthesized from the reaction of the bulky diketiminate lithium salt [HC(R)CNAr]2Li (1 Ar = 2,6-iPr2C6H3; R = tBu, 2 Ar = 2,4,6-Me3C6H2; R = Me) with MCl2 (M = Sn, Pb) affords 3 [HC(Me)CN(2,6-iPr2C6H3)]2SnCl and 4 [HC(Me)CN(2,4,6-Me3C6H2)]2PbCl. In the solid state, the structures indicate that the β-diketiminate backbone is essentially planar, and the metal centers reside in distorted tetrahedral environments with one vertex occupied by a lone pair of electrons. The bond angles at the metal center are in the range 82.5(5)-92.76(5)°, and the most acute angle is associated with the bite of the chelating ligand. Both compounds were characterized by elemental analysis, NMR, EI-MS, and single-crystal X-ray. We have investigated the influence of this lone pair on the geometries of the metal halide complexes 3 and 4, the isostructural tin and germanium complexes (3 and 5 respectively) using DFT calculations. B3LYP/LANDL2DZdp calculations show the lone pair in the lead complexes is significantly more diffuse than in the tin and germanium analogues and only a small amount of hybridization between the 6s and 6p orbitals is observed.

Abstract

Background: The genetic transformation of indicarice (Oryza sativa ssp. indica) is limited by its poor in vitro tissue culturability, especially callus browning. Elucidating the common wild rice (Oryza rufipogon Griff.) genes controlling callus browning is a literally fundamental method for improving the tissue culturability of indica rice varieties.
Methods and results: In the present study, we used a population of 129 O. rufipogon (Dongxiang common wild rice; DXCWR) introgression lines in the elite cultivar GC2 (Oryza sativa ssp. indica) background and 159 simple sequence repeat (SSR) markers to identify quantitative trait loci (QTLs) associated with callus browning in rice. The callus browning phenotype was evaluated using the indices of the callus browning rate (CBR), callus browning index (CBI), and standard callus browning index (SCBI).
Conclusions: We detected 30 QTLs associated with callus browning across the genotypes, which were located on chromosomes 1, 2, 3, 4, 8, 9, and 12. These were repeatedly associated with differences in CBR, CBI, and SCBI. The alleles from DXCWR had an additive effect in reducing callus browning. Especially, we identified new QTLs near RM247 an RM7003 on chromosome 12, indicating the QTLs were unique in DXCWR. Furthermore, we identified six introgression lines with significantly reduced callus browning, which is expected that these lines will be useful materials for the genetic transformation and fine mapping of the culturability trait.

Abstract

Background:We aimed to analyze the ethnic disparities in the out-of-pocket (OOP) payment and estimate the gaps related to observable risk factors in the OOP payment on medicines by ethnic conditions during 2014-2016 in Peru.Methods:We conducted a cross-sectional analytical secondary data analysis using the National Health User Satisfaction Survey. The outcome was the OOP payment in self-reported medications by participants. The ethnic condition was considered using the language participants habitually spoke at home (Spanish, Quechua/other). We collected confounding variables: sex, age, education, health insurance, medical prescription and region of residence. Crude and adjusted regression models were performed to assess the gaps in OPP payment on medications among ethnic conditions. The association measure was the Beta coefficient (β) with 95% confidence intervals (95%CI). The Oaxaca-Blinder decomposition method assessed the OPP payment differential in the two study groups explained by their individual and sociodemographic characteristics.Results:We analyzed 11,346 surveyed, the mean age was 40.78 years, and 57.67% were women. In the adjusted analysis, there was lower OOP payment in medications in participants speaking Quechua or other languages than those who speak Spanish (β: -0.11; 95%CI: -0.21 to -0.01; p=0.043). In the Oaxaca-Blinder decomposition analysis, a gap of 0.19 USD in the OOP payment in medicines was found, which disadvantages those minority ethnic conditions (p<0.001), and the explained component represents 41.2% of the gap (p<0.05).Conclusion:There were fewer out-of-pocket payments on medicines for ethnic minorities, and the observable differences explain approximately 40% of these gaps.

Abstract
During the COVID 19 pandemic, wearing a mask has become the norm for personal protection. Low-cost face masks made from different cloth materials are common in developing countries. The efficiency of a mask is characterized by its constituent materials; however, its fitting performance is not yet defined. In this study, low-cost mask designs for children were developed. Preferences of children were obtained via a survey. The morphologies of the masks were developed using geometric origami. An experimental visualization test was established by simulating sneezes of children, considered as the riskiest event by which the virus can be spread. Given the lack of data on children, the main features of their sneezes were scaled from adult data. A quantitative methodology was developed to assess the performance of a mask by using tracer particles and recording with high-speed cameras. Five mask configurations were analyzed, considering the mask size and the presence of a filter and a nose clip. The mask size and presence of a clip were identified as key factors affecting the fitting performance during a simulated sneeze.

Published: November 2022

Abstract
A significant proportion of patients experience a wide range of symptoms following acute coronavirus disease 2019 (COVID-19). Laboratory analyses of long COVID have demonstrated changes in metabolic parameters, suggesting that it is one of the many outcomes induced by long COVID. Here, we illustrate the clinical and laboratory markers related to the course of the disease in patients with long COVID. Participants were selected using a clinical care programme for long COVID in the Amazon region. Clinical and sociodemographic data and glycaemic, lipid, and inflammatory screening markers were collected, and cross-sectionally analysed between the long COVID-19 outcome groups. Of the 215 participants, most were female, not elderly, and 78 were hospitalised during the acute COVID-19 phase. The main long-term COVID symptoms reported were fatigue, dyspnoea, and muscle weakness. High body mass index and high triglyceride, HbA1c, and ferritin levels were related to worse long COVID scenarios. Our main findings indicate that abnormal metabolic profiles are related to worse long COVID presentations, suggesting that patients with long COVID may be more likely to develop clinical complications related to metabolic syndrome.
Temporal Super-Resolution using Smart Sensors for Turbulent Separated Flows
Authors: Manohar Kevin , Williams Owen , Martinuzzi Robert , Morton Chris 
Published: November 2022

Abstract
Particle image velocimetry (PIV) data of high Reynolds number unsteady turbulent flows are often undersampled in time; this leads to aliasing of important spectral content. The present work proposes a novel data-driven estimation technique that uses oversampled sparsely placed surface-mounted pressure sensors and long short-term memory (LSTM) neural networks to resolve the aliased transient velocity dynamics from undersampled PIV data. The method leverages the time-resolved pressure dynamics to estimate the temporal evolution of a proper orthogonal decomposition (POD)-based low-dimensional subspace of the velocity field. The proposed approach is demonstrated on a PIV dataset of a high Reynolds number turbulent separated flow over a Gaussian speed-bump benchmark geometry (ReH = 2.26 × 105, where H is the Bump height). The 15 Hz PIV data is super-resolved to 2 kHz, and spectral analysis of the flowfields is conducted to educe the originally aliased unsteady dynamics of the turbulent separation bubble. The estimator is shown to accurately reconstruct the Reynolds shear stress from unseen sensor data, demonstrating its generalizability to resolve the coherent motions. The estimated velocity spectra show distributions consistent with those of other separated flows

Abstract
Chemical insecticides are an important tool to control damaging pest infestations. However, lack of species specificity, the rise of resistance to these pesticides and the demand for biological alternatives with improved ecotoxicity profiles means that chemicals with new mode-of-actions are required. RNA interference (RNAi)-based strategies that use double-stranded RNA (dsRNA) as a species-specific bio-insecticide offer an exquisite solution that addresses these issues. Many species, such as the fruit pest Drosophila suzukii, are recalcitrant to RNAi when dsRNA is orally administered, due to degradation by gut nucleases and slow cellular uptake pathways. Thus, delivery vehicles that protect dsRNA and deliver it to insect gut cells are highly desirable. In this work, we demonstrate the complexation of D. suzukii-specific dsRNA for degradation of vha26 mRNA with bespoke, hydrophilic, diblock copolymers. To demonstrate the efficiency of this delivery system, we study the ex vivo protection of dsRNA against enzymatic degradation by gut enzymes. Flow cytometry is then used to investigate the cellular uptake of Cy3-labelled dsRNA, with confocal microscopy confirming cytoplasmic delivery after complexation. The polymer/dsRNA polyplexes induced significantly decreased survival of D. suzukii larvae following oral feeding, only when formed with a diblock copolymer containing a long neutral block length (1:2 cationic block/neutral block). However, there was no toxicity when fed to the closely related D. melanogaster. Thus, we provide evidence that dsRNA complexation with diblock copolymers is a promising strategy for RNAi-based species-specific pest control, however, optimisation of polymer composition is essential for RNAi success.

Abstract
Introduction: Today, many hospitals use a Pneumatic Tube System (PTS) to quickly convey specimens to the lab. This study examined the clinical and practical impacts of PTS in delivering specimens. Blood chemistry and hematologic parameters were compared between PTS and manual transfer to determine whether there was a significant increase or decrease in its values. The study evaluated the following Blood Chemistry parameters such as LDH, K, AST, ALP, ALT, and Total Bilirubin and Hematologic parameters such as Red Cell indices (MCV, MHC, and MCHC), RBC count, Hemoglobin and Hematocrit, Hemolysis rate, and Platelet count. The data are gathered to evaluate if PTS provides the same specimen integrity as the manual technique. In this project, the researchers will conduct a systematic review utilizing the PRISMA 2020 reporting checklist.
Methodology: Studies obtained from online databases were utilized. A set of criteria for selecting prospective studies were established. The studies should be published from 2017 to October 2022, must assess the effects of PTS by comparing them to manually transported samples, and must be fully accessible. Subgroup analysis and cumulative analysis were conducted to establish transparency of the results.
Findings and Discussion: A total of 27 studies were evaluated. Among these, 13 of the studies included are for blood chemistry and 15 studies are for hematology. Among all the parameters evaluated, only LDH, potassium, and Hemolysis index showed clinical significance between the samples transported via PTS and manually delivered. The other chemistry parameters were also increased but were not clinically significant. Whereas, Hematologic parameters have only limited studies available that can show that it is of clinical significance. However, most included studies utilized a small sample size and limited population, restricting further analysis of obtained results. Additionally, some were hindered due to insufficient data and information. Moreover, the technical aspects that can cause the results to differ are not provided because the PTS utilized to modify acceleration and deceleration, are not sufficiently described. Some research claimed that their study was restricted to PTS effects alone.
Enhanced effect of co-doping of Ln 3+ on the luminescent properties of BaSiO 3 :Eu 3+ red phosphors
Authors: Zhao Tianyang , Yang Lingxiang , Zhu Dachuan 
Published: November 2022

Abstract
In this work, Ba1 − xSiO3:xEu3+ and Ba0.84SiO3:0.08Eu3+,0.08Ln3+(Ln = La, Y or Gd)series phosphors are obtained by calcining the precursors pre-synthesized via chemical co-precipitation method. The XRD patterns demonstrate the main phase is a chain silicate BaSiO3 formed by (SiO3)2− groups and Ba2+ ions with monoclinic crystal. Under the monitoring of 616 nm emission, the PLE spectra of Ba1 − xSiO3:xEu3+ phosphors consist of several peaks at 246nm, 320 nm, 363 nm, 382 nm, 393 nm, 414 nm, 464 nm and 535 nm with the strongest intensity at 393 nm, while four emission peaks located at 591nm, 616nm, 654nm and 705nm are found under activation at 393 nm, attributed to the 55D0→7Fj༈j = 1,2,3,4༉transition of Eu3+ ions. The highest emission peak appears at 616 nm in the case of 8 mol% Eu3+ doping. Although the emission intensity of the phosphors decreases gradually with the temperature increasing, it can maintain at 43.4% of that at room temperature even up to 250℃. After co-doped with La3+, Y3+ or Gd3+ ions, the emission intensity of the phosphors at 616 nm is increased by 1.31, 1.32 or 1.75 times as a result of strengthening the crystal field, and the fluorescence lifetime is prolonged from 1.29 ms to 1.59 ms after co-doped Gd3+, ascribed to an energy transfer process of Gd3+→Eu3+. All these indicate the red phosphor has the potential in application for the white LEDs under the ultraviolet excitation.
