Published: September 2021

Objectives. To develop an imputation method to produce estimates for suppressed values within a shared government administrative data set to facilitate accurate data sharing and statistical and spatial analyses. Methods. We developed an imputation approach that incorporated known features of suppressed Massachusetts surveillance data from 2011 to 2017 to predict missing values more precisely. Our methods for 35 de-identified opioid prescription data sets combined modified previous or next substitution followed by mean imputation and a count adjustment to estimate suppressed values before sharing. We modeled 4 methods and compared the results to baseline mean imputation. Results. We assessed performance by comparing root mean squared error (RMSE), mean absolute error (MAE), and proportional variance between imputed and suppressed values. Our method outperformed mean imputation; we retained 46% of the suppressed value’s proportional variance with better precision (22% lower RMSE and 26% lower MAE) than simple mean imputation. Conclusions. Our easy-to-implement imputation technique largely overcomes the adverse effects of low count value suppression with superior results to simple mean imputation. This novel method is generalizable to researchers sharing protected public health surveillance data. (Am J Public Health. 2021; 111(10):1830–1838. https://doi.org/10.2105/AJPH.2021.306432 )

Objectives. To evaluate the efficacy of the Respecting the Circle of Life program (RCL) among Native American youths 11 to 19 years of age residing in a rural reservation community in the southwestern United States. Methods. Between 2016 and 2018, we conducted a randomized controlled trial of the RCL program with 534 Native youths. Participants completed assessments at baseline and 9 and 12 months after the intervention. We conducted intention-to-treat analyses based on study group randomization. Results. At 9 months, intervention participants had significantly better condom use self-efficacy (P < .001), higher intentions to use condoms (P = .024) and abstain from sex (P = .008), and better contraceptive use self-efficacy (P < .001) than control participants, as well as better condom use (P = .032) and contraceptive use (P = .002) negotiation skills. At 12 months, intervention participants had significantly better sexual and reproductive health knowledge (P = .021), condom use self-efficacy (P < .001), contraceptive use self-efficacy (P < .001), and contraceptive use negotiation skills (P = .004) than control participants. Intervention participants reported significantly more communication with their parents about sexual and reproductive health than control participants at both 9 and 12 months (P = .042 and P = .001, respectively). Conclusions. The RCL program has a significant impact on key factors associated with pregnancy prevention among Native youths and should be used as an adolescent pregnancy prevention strategy.

Integrity Evaluation of Cement Ring during Fracturing and Flowback of Horizontal Well in Jimsar Shale Oil
Authors: Yang Hu , Zhou Penggao , Xiong Chao , Yu Shifu , Li Jiancai 
Published: September 2021

Abstract
Horizontal well volume fracturing has become the main technology for effective development of unconventional oil and gas. In the process of fracturing and flowback of horizontal wells, the changes of wellbore temperature and pressure will affect the magnitude and distribution of stress in cement sheath, which may lead to compression or tensile failure of cement sheath, or a microclearance between casing and cement sheath. Therefore, based on the elastic theory of thick-walled cylinder, the elastic model of casing cement sheath and formation combination is established, and the finite difference program FLAC3D (Fast Lagrangian Analysis of Contimua in Three-Dimensional) was used to solve the model. The simulation evaluation of several horizontal wells in Jimusar shale oil shows that the main failure mode of cement sheath in horizontal well section is radial compression or circumferential tensile failure in fracturing period, and the main failure mode is a microclearance failure in flowback period. Taking Jimusar shale oil horizontal well JHW00421 as an example, the critical values of wellbore pressure and mechanical parameters of cement when cement sheath fails during fracturing flowback and their relationship are predicted or evaluated. The findings of this study are helpful to better understand and evaluate how different fracturing or flowback operation parameters affect the integrity of cement sheath and the effectiveness of interlayer sealing in horizontal well sections.

Published: September 2021

Abstract
The microscopic pore structure characteristics and the oil-water two-phase seepage law in the low permeability sandstone reservoir in Mobei oilfield in Junggar Basin were analyzed through laboratory experiments. The results of mercury pressure, constant velocity mercury pressure, thin slice of casting, and CT scan analyses showed that the reservoir had strong microheterogeneity with the presence of local large channels. The large channel had a small volume but considerably contributed to the permeability, which played a crucial role in the reservoir seepage. The relative permeability curve showed that with the increase of water saturation, the relative permeability of the oil phase decreased rapidly; the water phase relative permeability of glutenite, gravel-bearing sandstone, and coarse sandstone increased slightly; and the water cut increased rapidly. The relative permeability of the water phase of medium and fine sandstone increased, the water cut increased rapidly, and the residual oil saturation was high. In the process of core displacement, on-line CT scanning monitoring showed that before the breakthrough of the water drive front, the oil saturation decreased greatly along the way. After the breakthrough of the water drive front, the water cut increased rapidly and directly entered the ultrahigh water cut stage. Owing to the serious heterogeneity of the micropore structure, the fingering phenomenon was obvious in the process of displacement.

Abstract
Introduction To evaluate the pelvic floor muscle function (PFMF) of cervical cancer patients after type QM-C hysterectomy and to explore the relationship between decreased PFMF and related factors..Methods This was a multi-centered retrospective cohort study. 181 cervical cancer patients who underwent type QM-C hysterectomy were enrolled from 9 tertiary hospitals. Strength of PFMF were measured by using neuromuscular apparatus (Phenix U8, French). Risk factors contributing to decreased PFMF were analyzed by univariate and multivariate ordinal ploytomous logistic regression. Results Totally 181 patients were investigated in this study. 0-3 level of type I muscle fibre strength(MFSI) was 52.6% (95/181), 0-3 level of type ⅡA muscle fibre strength(MFSⅡA) was 50% (91/181). Subjective stress urinary incontinence was 46%(84/181), urinary retention was 27.3% (50/181), dyschezia was 41.5% (75/181), fecal incontinence was 9%(18/181). ① MFSI：Multivariate ordinal ploytomous logistic regression shows that the follow-up time(p<0.05), chemotherapy and radiotherapy (p=0.038) are independent risk factors of MFSI’s reduction after type QM-C hysterectomy. ② MFSⅡA：Multivariate ordinal ploytomous logistic regression shows that the follow-up time (p<0.05) are independent risk factors of MFSⅡA’s reduction after type QM-C hysterectomy. The pelvic floor muscle strength (PFMS) increased after 9 months than in 9 months after operation, which showed that the PFMS could be recovered after operation. Conclusions We advocate for more attention and emphasis on the PFMF of Chinese female patients with cervical cancer postoperation.Contribution of the Paper PFMF after QM-C hysterectomy has not been analyzed by current study. The contribution is that patients with radical hysterectomy should do pelvic floor rehabilitation exercises in 3 months after operation.

Published: September 2021

Abstract
Background:Clinical reasoning is a crucial task within the Emergency Medical Services (EMS) care process. Both contextual and cognitive factors make the task susceptible to errors. Understanding the EMS care process’ structure could help identify and address issues that interfere with clinical reasoning. The EMS care process is complex and only basically described. In this research, we aimed to define the different phases of the process and develop an overarching model that can help detect and correct potential error sources, improve clinical reasoning and optimize patient care. Methods:We conducted a focused ethnography study utilizing non-participant video observations of real-life EMS deployments combined with thematic analysis of peer interviews.After an initial qualitative analysis of 7 video observations, we formulated a tentative conceptual model of the EMS care process. To test and refine this model, we carried out a qualitative, thematic analysis of 28 video-recorded cases. We validated the resulting model by evaluating its recognizability with a peer content analysis utilizing semi-structured interviews. Results:Based on real-life observations, we were able to define and validate a model covering the distinct phases of an EMS deployment. We have introduced the acronym “SPART” to describe ten different phases: Start, Situation, Prologue, Presentation, Anamnesis, Assessment, Reasoning, Resolution, Treatment, and Transfer. Conclusions: The “SPART” model describes the EMS care process and helps to understand it. We expect it to facilitate identifying and addressing factors that influence both the care process and the clinical reasoning task embedded in this process.

Authors: Biswas Mandira , Dey Anup , Sarkar Subir Kumar 
Published: September 2021

Abstract
In this present research work, we presented a new Bottom Gate P-Type Organic Field Effect Transistor (OFET) humidity sensor and its applicability towards humidity has been experimentally demonstrated. P-type organic semiconductor polyaniline (PANI) has been used in a variety of applications, including logic circuit components, electromagnetic shielding, chemical sensing, and anticorrosion. Humidity sensor can be used to monitor relative humidity (RH) in various environments. We only focus on the fabrication of conducting polymer OFETs with top contact to measure humidity and verify I-V properties. The current saturation (ISat) of p-type OFETs was 0.8 μA, while the threshold voltage VTh was 2.2V. The results of FESEM have been perform to confirm that deposited thin film grown on the substrate is purely uniform. The Proposed sensor shows that organic gate dielectrics are a low-cost alternative to inorganic gate dielectrics with good electrical performance. The proposed OFET-based sensors have a number of benefits, such as high sensitivity, low cost, quick response, and physical flexibility.
Prevalence of Suicidal Ideation and Suicide Attempts Among Refugees: A Meta-analysis

Published: September 2021

Abstract
Background: Suicidal ideation and attempts are one of the most serious mental health problems affecting refugees. Risk factors such as mental disorders, low socio-economic status, and stressful life events all contribute to making refugees a high-risk group. For this reason, this meta-analysis aims to investigate the prevalence of suicidal ideation and attempts among refugees in non-clinical populations.Method: All studies published in English up through August 2020 were considered for the analysis. We searched four databases for articles reporting (period) prevalence rates of suicidal ideation and attempts. Results: Of 294 hits, 11 publications met the inclusion criteria. Overall prevalence rates were calculated using Rstudio. The overall period prevalence of suicidal ideation was 20.5% (CI: 0.11-0.32, I²=98%, n=8), 22.3% (CI: 0.10-0.38, I²=97%, n=5) for women, and 23.3% for men (CI: 0.13-0.35, I²=87%, n=3). Suicide attempts had an overall prevalence of 0.57% (CI: 0.00-0.02, I²=81%, n=4). Conclusion: There is a great lack of epidemiological studies on suicidal ideation and attempts among refugees. The high prevalence of suicidal ideation indicates the existence of heavy psychological burden among this population. The prevalence of suicide attempts is similar to that in non-refugee populations. In addition, the results underline the need for systematic and standardized assessment and treatment of suicidal ideation and attempts.
The relationship between psychosocial factors and reported disability: The role of pain self-efficacy
Authors: Varela Antonio 
Published: September 2021

Abstract
Background
Chronic pain in all its forms and the accompanying level of disability is a healthcare crisis that reaches epidemic proportions and is considered a world level crisis. Chronic non-specific low back pain contributes a significant proportion of chronic pain. Specific psychosocial factors and their influence on reported disability in a chronic non-specific low back pain (CNLBP) population was researched.
Methods
Psychosocial factors examined include fear, catastrophizing, depression, and pain self-efficacy. This cross-sectional correlational study examined the mediating role between pain self-efficacy and the specific psychosocial factors with reported disability. The study included 90 participants with CNLBP between 20 and 60 years of age. Participants completed the Fear Avoidance Belief Questionnaire, The Pain Catastrophizing Scale, The Patient Health Questionnaire-9, The Pain Self-Efficacy Questionnaire, and The Lumbar Oswestry Disability Index to measure fear of physical activity, pain catastrophizing, depression, pain self-efficacy, and reported disability, respectively. The study used multivariate regression and mediation analyses.
Results
The principal finding of the study was a strong inverse relationship between pain self-efficacy and reported disability. Further, pain self-efficacy was considered a statistic mediator for all psychosocial factors investigated within this data set. Pain self-efficacy was strongly considered to have a mediating role between reported fear of physical activity and disability, reported pain catastrophizing and disability, and reported depression and disability. Additionally, adjusting for age and reported pain levels proved to be statistically significant, and it did not alter the role of pain self-efficacy.
Conclusion
The results identified that pain self-efficacy had a mediating role in the relationship between the specific psychosocial factors of fear, catastrophizing, and depression and reported disability. Pain self-efficacy plays a more significant role in the relationships between specific psychosocial factors and reported disability with CNLBP than previously considered.

Published: September 2021

Abstract
Background

Elderly residents in nursing homes are at high risk for dysphagia. However, the prevalence estimates of this condition and its risk factors among this population were inconsistent.
Objective

To estimate the prevalence of dysphagia and examine its risk factors among the elderly in nursing homes.
Methods

Electronic database of PubMed, Web of science, Embase for English language, Wangfang, VIP and CNKI for Chinese language were systematically searched to identify relevant observational studies published not later than July 4, 2021. Studies conducted in nursing homes and reported dysphagia assessment methods were included.
Results

In total, 43 studies involving 56,746 participants were included in this systematic review and meta-Analysis. The overall pooled crude prevalence of dysphagia was 35.9% (95%CI: 29.0%, 43.4%), with high heterogeneity (I2 = 99.5%). There was a statistically significant difference in prevalence estimates with respect to study locations, methods of assessment of dysphagia, dysphagia assessment staff, representativeness of samples, and validity of assessment tools. Pooled estimates indicated that male (OR = 1.13, 95%CI: 1.00, 1.27), cognitive impairment (OR = 2.47, 95%CI: 1.59, 3.84), functional limitation (OR = 2.59, 95% CI: 1.75, 3.84), cerebrovascular disease (OR = 2.90, 95%CI: 1.73,4.87), dementia (OR = 1.50, 95%CI: 1.15, 1.96) and Parkinson’s disease (OR = 1.81, 95%CI: 1.06, 3.08) were significant risk factors for dysphagia.
Conclusions

The prevalence of dysphagia in nursing homes is relatively high, and with high heterogeneity. Also, many factors were associated with the risk of dysphagia. Further research is needed to identify strategies for management and interventions targeted at these disorders in this population.

Abstract
Background

As the incidence of intracranial infections increase due to diagnostic procedures improvement, more real-life data is needed to reach a more solid informed management approach. This study aims to describe and analyse clinical features of intracranial abscesses patients treated at a tertiary hospital in North Jordan during a 10-year period.
Methods

We retrospectively identified 37 patients treated at King Abdullah University Hospital (KAUH) from 2011 to 2020 in Irbid, North Jordan. Treatment consisted of either aspiration, open craniotomy excision (OCE) or conservative therapy. Extracted variables included demographic data such (age, gender), clinical presentation, lab findings, radiological findings as well as management plan. Retrieved data was compared between the patients who underwent a single operation and those who underwent reoperation after the initial procedure.
Results

Thirty-seven patients with 55 intracerebral abscesses were identified, 29 of whom had intraparenchymal brain abscesses, 4 patients had epidural empyema, and 4 had subdural empyema. The mean age was 28.8 (± 20.7) years, with a male predominance (78.4%). Sixteen patients underwent open craniotomy excision (OCE), 14 patients were treated by aspiration and 7 patients were treated conservatively. When comparing the single operation and the reoperation groups, there was no statistically significant difference across variables.
Conclusion

Our study presents valuable insight from a tertiary hospital in north Jordan on intracranial abscesses and empyemas. Our findings confirm that good recovery can be established after aspiration or OCE in the majority of patients. Similar results were obtained when comparing the SOP and the ROP groups.
