Accounting for regional transmission variability and the impact of malaria control interventions in Ghana: a population level mathematical modelling approach
Authors: Awine Timothy , Silal Sheetal P. 
Published: November 2020

Abstract
Background
This paper investigates the impact of malaria preventive interventions in Ghana and the prospects of achieving programme goals using mathematical models based on regionally diverse climatic zones of the country.

Methods
Using data from the District Health Information Management System of the Ghana Health Service from 2008 to 2017, and historical intervention coverage levels, ordinary non-linear differential equations models were developed. These models incorporated transitions amongst various disease compartments for the three main ecological zones in Ghana. The Approximate Bayesian Computational sampling approach, with a distance based rejection criteria, was adopted for calibration. A leave-one-out approach was used to validate model parameters and the most sensitive parameters were evaluated using a multivariate regression analysis. The impact of insecticide-treated bed nets and their usage, and indoor residual spraying, as well as their protective efficacy on the incidence of malaria, was simulated at various levels of coverage and protective effectiveness in each ecological zone to investigate the prospects of achieving goals of the Ghana malaria control strategy for 2014–2020.

Results
Increasing the coverage levels of both long-lasting insecticide-treated bed nets and indoor residual spraying activities, without a corresponding increase in their recommended utilization, does not impact highly on averting predicted incidence of malaria. Improving proper usage of long-lasting insecticide-treated bed nets could lead to substantial reductions in the predicted incidence of malaria. Similar results were obtained with indoor residual spraying across all ecological zones of Ghana.

Conclusions
Projected goals set in the national strategic plan for malaria control 2014–2020, as well as World Health Organization targets for malaria pre-elimination by 2030, are only likely to be achieved if a substantial improvement in treated bed net usage is achieved, coupled with targeted deployment of indoor residual spraying with high community acceptability and efficacy.
Geographic Ecological Momentary Assessment (GEMA) of environmental noise annoyance: the influence of activity context and the daily acoustic environment
Authors: Zhang Xue , Zhou Suhong , Kwan Mei-Po , Su Lingling , Lu Junwen 
Published: November 2020

Abstract
Background
Noise annoyance is considered to be the most widespread and recognized health effect of environmental noise. Previous research is mostly based on the static study of residential environmental noise, but few studies have focused on the effects of noise exposure in different activity contexts on real-time annoyance. The two deficiency are that they neglect the influence of activity context besides residence and fail to reflect the difference of time-scale effect of noise influence.

Methods
Using portable noise and air sensors, GPS-equipped mobile phones, questionnaire survey, and geographic ecological momentary assessment (GEMA), this paper measured the environmental noise and real-time noise annoyance of participants at different activity places. Hierarchical logistic regression models were used to examine the effects of environmental noise on people’s real-time annoyance. The paper further considered the influence of the geographic context of the activity places and daily acoustic environment on participants’ real-time annoyance. Further, a nonlinear regression model was constructed using Random Forest to further examine the nonlinear relationship between environmental noise and real-time annoyance.

Results
The results showed that: (1) the average cumulative equivalent sound level during was 55 dB (A) when the participants responded to the EMA surveys; (2) Only the temperature of activity places had an influence on momentary annoyance and the higher the temperature, the more likely participants were annoyed; (3) Participants with higher perception of noise pollution in residential communities were more likely to be annoyed. However, participants with higher daily exposure to noise were less likely to feel annoyed; (4) The threshold value of the effect of noise on real-time annoyance was 58 dB (A) to 78 dB (A).

Conclusions
These findings can guide the development of urban planning and environmental noise standards and also provide a reference for noise barrier requirements for different activity places.
Measuring parent proxy-reported quality of life of 11 rare diseases in children in Zhejiang, China
Authors: Gao Qisheng , Wang Shanshan , Ren Jianping , Wen Xin 
Published: November 2020

Abstract
Background
It has become increasingly important to measure the health-related quality of life (HRQoL) of rare diseases in children and adolescents in recent decades. Much attention has been paid to investigate the HROoL of a specific rare disease by self-report in previous studies. This study aimed to evaluate and compare the HROoL of 11 rare diseases in Chinese children by parent proxy-report, to explore the factors associated with HROoL of patients, and to understand the problems of most concern.

Methods
A total of 651 children aged from 2 to 18 were enrolled from the Children’s Hospital Affiliated Zhejiang University in 2018. Their parents completed the parent proxy-report version of the Pediatric Quality of Life Inventory™ 4.0 (PedsQL™ 4.0). Independent samples t-test, one-way ANOVA, or Kruskal–Wallis H test was used to compare HROoL scores between groups. Multilevel linear regression models with random intercept were applied to analyze the relationship between socioeconomic variables and both the total score and subdomain scores.

Results
The total PedsQL scores of Patent ductus arteriosus (PDA), Infantile agranulocytosis, Autoimmune thrombocytopenia (ITP), Polysyndactyly, Hirschsprung disease, Cleft lip and palate, Tetralogy of fallot, Myasthenia gravis, Guillain–barre syndrome, Glycogen storage disease, and Langerhans cell histiocytosis children were 79.65 ± 5.46, 95.88 ± 3.48, 71.39 ± 3.27, 91.77 ± 6.35, 76.18 ± 6.92, 96.33 ± 4.22, 77.85 ± 8.90, 95.99 ± 3.31, 85.77 ± 4.56, 82.97 ± 4.13 and 77.6 ± 5.15, respectively. Age was significantly associated with physical functioning, school functioning, and psychosocial health scores. The household registration place was significantly related to the total score. The most urgent desire of patients was to reduce the overall medical costs.

Conclusions
This study showed that patients with PDA had the lowest physical functioning score, while patients with ITP scored the lowest in the emotional functioning, social functioning, school functioning, psychosocial health, and total scores. Incentive policies should be further adopted to improve orphan drug availability and reduce the economic burden of rare diseases.
Lateral lymph node dissection reduces local recurrence of locally advanced lower rectal cancer in the absence of preoperative neoadjuvant chemoradiotherapy: a systematic review and meta-analysis
Authors: Gao Xiang , Wang Cun , Yu Yongyang , Singh Dujanand , Yang Lie , Zhou Zongguang 
Published: November 2020

Abstract
Background
The impact of lateral lymph node dissection (LLND) in locally advanced lower rectal cancer remains controversial. This study is to compare total mesorectal excision (TME) with or without LLND in lower rectal cancer cases of stage II/III.

Methods
The electronic databases were systematically searched that compared TME with or without LLND among patients with lower rectal cancer in clinical stage II/III. Subgroup analysis was performed considering neoadjuvant chemoradiotherapy (nCRT). The hazard ratios (HR), relative risk (RR), and weighted mean difference (WMD) were pooled.

Results
Twelve studies of 4458 patients of this meta-analysis demonstrate, LLND alone significantly reduced the local recurrence rate of patients who did not receive nCRT (RR 0.71, P = 0.004), while the difference was not significant when combined with nCRT (RR 0.70, P = 0.36). The analysis shows TME with LLND was associated with significantly longer operation time (WMD 90.73 min, P < 0.001), more intraoperative blood loss (WMD 303.20 mL, P < 0.001), and postoperative complications (RR = 1.35, P =0.02). Whereas urinary dysfunction (RR 1.44, P = 0.38), sexual dysfunction (RR 1.41, P = 0.17), and postoperative mortality (RR = 1.52, P = 0.70), were similar between these two groups. Statistically, no significant differences were observed in OS (HR 0.93, P = 0.62), DFS (HR 0.99, P = 0.96), total recurrence (RR 0.98, P = 0.83), lateral recurrence (RR 0.49, P = 0.14), or distal recurrence (RR 0.95, P = 0.78) between these two groups regardless of whether nCRT was performed or not.

Conclusions
The study shows LLND alone decreases the local recurrence without using nCRT irrespective of the survival advantage in locally advanced lower rectal cancer. The benefit of controlling local recurrence by LLND alone makes us reconsider the usage of nCRT with LLND.

Trial registration
The protocol for this meta-analysis was registered prospectively with PROSPERO (CRD42020135575) on 16 May 2019.
Irreversible electroporation in patients with liver tumours: treated-area patterns with contrast-enhanced ultrasound
Authors: Zhou Linyu , Yin Shanyu , Chai Weilu , Zhao Qiyu , Tian Guo , Xu Danxia , Jiang Tian’an 
Published: November 2020

Abstract
Background
Familiarity with post-IRE imaging interpretation is of considerable importance in determining ablation success and detecting recurrence. CEUS can be used to assess the tumour response and characteristics of the ablation zone. It is of clinical interest to describe the ultrasonographic findings of liver tumours after irreversible electroporation (IRE) percutaneous ablation.

Methods
A prospective study of 24 cases of malignant liver tumours (22 cases of primary liver tumours and 2 cases of liver metastases) treated by IRE ablation was conducted. Two inspectors evaluated the ablation zone in a consensus reading performed immediately, 1 day, and 1 month after IRE ablation. The gold standard method, magnetic resonance imaging (MRI), was used to evaluate the effectiveness of the treatment at 1 month.

Results
Immediately after IRE ablation and up to 1 month later, the ablation zones gradually changed from hypo-echogenicity to hyper-echogenicity on conventional ultrasound and showed non-enhancement on contrast-enhanced ultrasound (CEUS). One month after IRE ablation, CEUS and MRI results were highly consistent (κ = 0.78, p < 0.05).

Conclusions
We conclude that CEUS may be an effective tool for assessing post-IRE ablation changes after 1 month. CEUS enables the depiction of tumour vascularity in real time and serves as an easy, repeatable method.
Acceptability of menstrual products interventions for menstrual hygiene management among women and girls in Malawi
Authors: Kambala Christabel , Chinangwa Angela , Chipeta Effie , Torondel Belen , Morse Tracy 
Published: November 2020

Abstract
Background
A key challenge for menstruating girls and women in low-resource countries is the inadequate and unreliable supply of menstrual products. Although development partners are implementing menstrual product interventions to address this challenge in Malawi, there is a paucity of information on the distribution of menstrual products and the acceptability of these interventions among users.

Methods
We conducted in-depth interviews with girls (n = 20) and women (n = 26) and 4 focus group discussions (FGDs) with women (n = 35) and 7 FGDs with girls (n = 60) to explore the acceptability of menstrual products interventions in 8 districts. Teachers (n = 12), community leaders (n = 6), community health workers (n = 8) and service providers (n = 9) were also interviewed to explore implementation issues and their views regarding the effect of menstrual products interventions on girls and women. Data were analyzed using content analysis.

Results
Common menstrual products being promoted include locally made reusable pads, commercially made disposable pads and menstrual cups. Overall, adult women preferred reusable pads and young girls preferred disposable pads. Reported benefits of using any type of material distributed included enhanced cleanliness and reduced school absenteeism for girls. While community leaders and teachers applauded the use of disposable menstrual products they expressed concern that they are not affordable for an average Malawian and bemoaned the indiscriminate disposal of used disposable pads. Women and girls highlighted their lack of facilities to effectively wash and dry reusable pads. Service providers bemoaned poor coordination and the lack of national standards to regulate the quality of menstrual products distributed at national level. Improved inclusion of males and health workers could enhance the sustainability of programmes.

Conclusion
While the available menstrual products interventions are acceptable among participants, we note several challenges including affordability, poor disposal methods, lack of attention on sanitation facilities and the lack of standard protocols to regulate the quality of menstrual products. Recommendations to address these issues are reported.

Authors: Qiu Qinyin , Cronce Amanda , Patel Jigna , Fluet Gerard G. , Mont Ashley J. , Merians Alma S. , Adamovich Sergei V. 
Published: November 2020

Abstract
Background
After stroke, sustained hand rehabilitation training is required for continuous improvement and maintenance of distal function.

Methods
In this paper, we present a system designed and implemented in our lab: the Home based Virtual Rehabilitation System (HoVRS). Fifteen subjects with chronic stroke were recruited to test the feasibility of the system as well as to refine the design and training protocol to prepare for a future efficacy study. HoVRS was placed in subjects’ homes, and subjects were asked to use the system at least 15 min every weekday for 3 months (12 weeks) with limited technical support and remote clinical monitoring.

Results
All subjects completed the study without any adverse events. Subjects on average spent 13.5 h using the system. Clinical and kinematic data were collected pre and post study in the subject’s home. Subjects demonstrated a mean increase of 5.2 (SEM = 0.69) on the Upper Extremity Fugl-Meyer Assessment (UEFMA). They also demonstrated improvements in six measurements of hand kinematics. In addition, a combination of these kinematic measures was able to predict a substantial portion of the variability in the subjects’ UEFMA score.

Conclusion
Persons with chronic stroke were able to use the system safely and productively with minimal supervision resulting in measurable improvements in upper extremity function.
A cassava protoplast system for screening genes associated with the response to South African cassava mosaic virus
Authors: Chatukuta Patience , Rey Marie Emma Christine 
Published: November 2020

AbstractBackgroundThe study of transient gene expression in cassava plants during virus infection using existing protocols is laborious and may take approximately fifteen weeks due to cassava’s recalcitrance to transformation. The combination of a protoplast system with CRISPR-mediated gene editing promises to shorten the turnaround time from plant tissue culture to high-throughput gene expression screening for candidate genes. Here, we detail a protocol for screening genes associated with the response to South African cassava mosaic virus (SACMV) in cassava protoplasts, with reference to the ubiquitin E3 ligase gene,MeE3L.MethodsCassava protoplasts of model, and SACMV-susceptible and -tolerant genotypes, were transformed with SACMV infectious clones and/or a CRISPR-editing construct targeting theMeE3Lusing PEG4000-mediated transfection. DNA and RNA were extracted from transformed protoplasts at 24 h post-transfection. Relative SACMV DNA accumulation was determined via qPCR usingDpnI-digested total DNA,MeE3Lrelative expression was determined via reverse transcriptase qPCR, and results were analysed using one-way ANOVA, Tukey’s HSD test and the 2−ΔΔCTstatistical method. TheMeE3L exonic region was sequenced on the ABI 3500XL Genetic Analyzer platform; and sequences were analysed for mutations using MAFTT and MEGA-X software. Construction of a phylogenetic tree was done using the Maximum Likelihood method and Jones-Taylor-Thornton (JTT) matrix-based model.ResultsThe differential expression of unedited and mutantMeE3Lduring SACMV infection of model, susceptible and tolerant cassava protoplasts was determined within 7 weeks after commencement of tissue culture. The study also revealed that SACMV DNA accumulation in cassava protoplasts is genotype-dependent and induces multiple mutations in the tolerant landraceMeE3Lhomolog. Notably, the susceptible cassava landrace encodes a RINGless MeE3Lwhich is silenced by SACMV-induced mutations. SACMV also induces mutations which silence theMeE3LRING domain in protoplasts from and tolerant cassava landraces.ConclusionsThis protocol presented here halves the turnaround time for high-throughput screening of genes associated with the host response to SACMV. It provides evidence that a cassava E3 ligase is associated with the response to SACMV and forms a basis for validation of these findings byin planta functional and interaction studies.

Authors: Wang Zhiling , Gu Ying , Wang Hui , Chen Junyu , Zheng Yawen , Cui Baoxia , Yang Xingsheng 
Published: November 2020

Abstract
Background
To investigate distributions of cervical lesions and factors associated with the severity of the cervical lesions in high-risk HPV (hr-HPV) positive women with atypical squamous cells of undetermined significance (ASC-US) cytology.

Methods
Clinical information of 250,000 women who underwent HPV and cytological test was collected from January 2012 to January 2019. The association between the severity of the cervical lesions and hr-HPV genotypes, hr-HPV viral load, and ages, were analyzed in hr-HPV-positive/ASC-US women.

Results
3459 hr-HPV-positive/ASC-US women were enrolled in this study. Overall, 43.51% of women with ASC-US had normal histological results, 34.35% had high-grade squamous intraepithelial lesion (HSIL), and 1.30% had cervical cancer. The rate of HSIL or worse (HSIL+) in women with single HPV16 infection (63.09%) was the highest, followed by HPV33 (57.50%), HPV51 (36.11%), HPV58 (36.11%), HPV52 (28.28%), HPV18 (26.37%), HPV66 (19.35%), HPV39 (18.92%), HPV53 (15.00%), and HPV56 (8.51%). Detection rate of HSIL+ in low, intermediate and high viral-load groups were 15.87% (n = 30), 34.91% (n = 74) and 40.68% (n = 214) (Cochran-Armitage Trend test χ2 = 35.03, p < 0.0001). Compared with the 51–60-year-old group (21.65%), the women in ≤ 30 (40.52%), 31–40 (39.67%), and 41–50 (34.22%) year-old groups had significantly higher risk of HSIL+. The women in ≤ 51–60 (2.68%) and > 60 (3.41%) year-old groups were at increased risk for cervical cancer, compared with the ≤ 30-year-old group (0.61%).

Conclusions
ASC-US women with HPV 16/18/33/51/52/58 single infection and multiple infections, as well as high HPV viral loads, have high risk of HSIL+.
“Students in public and private schools—which are at higher risk of drug use?”: a survey from Iran
Authors: Bahramnejad Ali , Iranpour Abedin , Nakhaee Nouzar 
Published: November 2020

Abstract
Background
Recent evidence from Western countries suggests that private school students are more prone to drug use. Such an evidence is lacking in Muslim countries. The aim of this study was to examine whether the risk of drug use is higher in private schools than public schools.

Methods
This cross sectional study was conducted on 650 tenth grade students of Kerman city, the center of largest province of Iran using cluster sampling. Well-validated questionnaires regarding current, lifetime substance use, and perceived use by classmates were utilized. Substances included in the questionnaire were waterpipe, cigarette, alcohol, marijuana, opium, methamphetamine, and Naas. Drug Use Tendency Scale was used to measure the attitudes of students towards drug use.

Results
The response rate was 93.7%. More than 82% of sample were public school students (n = 504). Current use of cigarette and marijuana was higher in private schools (12.2 and 3.0%, respectively) than public schools (4.4 and 0.5%, respectively) (P < 0.05). Perceived prevalence of cigarette smoking by classmates was higher among private school students.

Conclusion
Despite the popular belief that private schools are better than public schools regarding the risk of substance use, students who attend private schools may be at a higher risk of turning to some drugs comparing to public schools in Iran.
Whole-brain irradiation differentially modifies neurotransmitters levels and receptors in the hypothalamus and the prefrontal cortex
Authors: Franco-Pérez Javier , Montes Sergio , Sánchez-Hernández Josué , Ballesteros-Zebadúa Paola 
Published: November 2020

Abstract
Background
Whole-brain radiotherapy is a primary treatment for brain tumors and brain metastasis, but it also induces long-term undesired effects. Since cognitive impairment can occur, research on the etiology of secondary effects has focused on the hippocampus. Often overlooked, the hypothalamus controls critical homeostatic functions, some of which are also susceptible after whole-brain radiotherapy. Therefore, using whole-brain irradiation (WBI) in a rat model, we measured neurotransmitters and receptors in the hypothalamus. The prefrontal cortex and brainstem were also analyzed since they are highly connected to the hypothalamus and its regulatory processes.

Methods
Male Wistar rats were exposed to WBI with 11 Gy (Biologically Effective Dose = 72 Gy). After 1 month, we evaluated changes in gamma-aminobutyric acid (GABA), glycine, taurine, aspartate, glutamate, and glutamine in the hypothalamus, prefrontal cortex, and brainstem according to an HPLC method. Ratios of Glutamate/GABA and Glutamine/Glutamate were calculated. Through Western Blott analysis, we measured the expression of GABAa and GABAb receptors, and NR1 and NR2A subunits of NMDA receptors. Changes were analyzed comparing results with sham controls using the non-parametric Mann–Whitney U test (p < 0.05).

Results
WBI with 11 Gy induced significantly lower levels of GABA, glycine, taurine, aspartate, and GABAa receptor in the hypothalamus. Also, in the hypothalamus, a higher Glutamate/GABA ratio was found after irradiation. In the prefrontal cortex, WBI induced significant increases of glutamine and glutamate, Glutamine/Glutamate ratio, and increased expression of both GABAa receptor and NMDA receptor NR1 subunit. The brainstem showed no statistically significant changes after irradiation.

Conclusion
Our findings confirm that WBI can affect rat brain regions differently and opens new avenues for study. After 1 month, WBI decreases inhibitory neurotransmitters and receptors in the hypothalamus and, conversely, increases excitatory neurotransmitters and receptors in the prefrontal cortex. Increments in Glutamate/GABA in the hypothalamus and Glutamine/Glutamate in the frontal cortex indicate a neurochemical imbalance. Found changes could be related to several reported radiotherapy secondary effects, suggesting new prospects for therapeutic targets.
