Trends in Stimulant and Sedative/Hypnotic Dispensing: An Exploratory Study

Objective: To investigate patterns and trends of co-prescriptions of stimulants and sedatives within the last 6 years at a tertiary care center. Method: Patients 18 years of age and older who were dispensed at least one stimulant prescription from an institutional pharmacy between 1/1/2015 and 7/1/2021 were included. Prescription data for any co-prescribed sedative/hypnotic were collected. Results: Both the number of stimulant dispenses and the number of patients with stimulant dispenses increased significantly with yearly incidence rate ratios of 1.115 (95% CI [1.110, 1.119]) and 1.090 (95% CI [1.084, 1.096]), respectively. The number of patients with a stimulant dispensed who also had a benzodiazepine or “Z-drug” sedative-hypnotic dispensed at any point in the search timeframe increased significantly with incidence rate ratios of 1.077 and 1.092, respectively. The number of stimulant dispenses, number of patients with stimulant dispenses, and number of patients with a stimulant dispensed who also had both a benzodiazepine and Z-drug dispensed at any point in the search timeframe increased significantly more in Non-White than in White patients. Conclusions: The results confirm previous findings of increases in dispensing of stimulants over the past 6 years and report increased polypharmacy of stimulants and sedative-hypnotics.

Efficacy and safety of novel biologics in the treatment of lupus nephritis based on registered clinical trials: a systematic review and network meta-analysis.

To compare the clinical effectiveness and safety of novel biologics for the treatment of lupus nephritis based on a reticulated meta-analysis approach. Registered clinical trials in 4 major databases (PubMed, Embase, Web of Science, The Cochrane Register of Clinical Trials) and ClinicalTrials.gov were systematically searched with a search time frame of build to June 2022. And we screened registered randomized controlled clinical trials of biologics for the treatment of lupus nephritis according to the protocol's nadir criteria. Trials were evaluated for quality using the Cochrane Risk of Bias Assessment Tool, and data were statistically analyzed using Stata 16.0 and Review Manager 5.3 software to compare and rank differences in effectiveness and safety between the biologics. A total of 10 registered randomized controlled clinical trials involving 2148 subjects were included in this study. The interventions were ranked from best to worst in terms of the primary outcome indicator of effectiveness, renal complete remission: belimumab > anifrolumab (900 + 300) mg > obinutuzumab > ocrelizumab 400mg > abatacept 30/10mg/kg > belimumab + rituximab > abatacept 10/10mg/kg > abatacept (30/10 + 10/10) mg/kg > placeo > ocrelizumab 1000mg > rituximab > anifrolumab 300mg, belimumab was superior to placebo [OR = 1.75, 95% CI (1.13, 2.70)] and anifrolumab 300mg [OR = 3.27, 95% CI (1.05, 10.14)], anifrolumab (900 + 300) mg was superior to anifrolumab 300mg [OR = 3.56, 95% CI (1.30, 9.76)], and all were statistically significant. The ranking of each intervention in terms of overall renal remission for secondary outcome indicators from best to worst was: obinutuzumab > belimumab + rituximab > anifrolumab (900 + 300) mg > ocrelizumab 1000mg > ocrelizumab 400mg > belimumab > rituximab 1000mg > abatacept 30/10mg/kg > abatacept (30/10 + 10/10) mg/kg > placeo > abatacept 10/10mg/kg > anifrolumab 300mg, obinutuzumab was superior to placebo [OR = 2.27, 95% CI (1.11, 4.67)] and belimumab was also superior to placebo [OR = 1.56, 95% CI (1.07, 2.27)], and all were statistically significant. In terms of safety, with a focus on serious adverse events and serious infections, the results were: Serious adverse events at 1year of monitoring occurred better with ocrelizumab 1000mg than ocrelizumab 400mg [OR = 0.51, 95% CI (0.29, 0.89)] and were statistically different; serious adverse events at 2years of monitoring infection adverse events occurred better with obinutuzumab than with abatacept (30/10 + 10/10) mg/kg [OR = 0.24, 95% CI (0.07, 0.81)] and were statistically different. The safety of the new biologics in combination with conventional standard therapies is generally good, but it is belimumab and obinutuzumab that are most effective in achieving complete and overall remission in the kidney. This study protocol has been registered with PROSPERO, with a registration number of CRD42021262498.

The role of robotic retroperitoneal lymph node dissection in testicular cancer: a systematic review and meta-analysis.

To compare the safety and efficacy of robotic-assisted retroperitoneal lymph node dissection (RA-RPLND) versus non-robotic retroperitoneal lymph node dissection in testicular cancer. The statistical analysis software used Stata 17. The weighted mean difference (WMD) represents the continuous variable, and the dichotomous variable chooses the odds ratio, and calculates the 95% CI. This systematic review and cumulative meta-analysis was performed according to PRISMA criteria, and AMSTAR guidelines (assessing the methodological quality of systematic reviews). The Embase, PubMed, Cochrane Library, Web of Science, and Scopus databases were searched. The upper limit of the search time frame was February 2023, and no lower limit was set. Seven studies involving 862 patients. Compared with open retroperitoneal lymph node dissection, RA-RPLND appears to have a shorter length of stay [WMD=-1.21, 95% CI (-1.66, -0.76), P <0.05], less estimated blood loss [WMD=-0.69, 95% CI (-1.07, -0.32), P <0.05], and lower overall complications [odds ratio=0.45, 95% CI (0.28, 0.73), P <0.05]. RA-RPLND appears to have more lymph node yields than laparoscopic retroperitoneal lymph node dissection [WMD=5.73, 95% CI (1.06, 10.40), P <0.05]. However, robotic versus open/laparoscopic retroperitoneal lymph node dissection had similar results in operation time, lymph node positivity rate, recurrence during follow-up, and postoperative ejaculation disorders. RA-RPLND appears to be safe and effective for testicular cancer, but longer follow-up and more studies are needed to confirm this.

Using AGREE II reporting checklist to evaluate the quality of Tuina clinical practice guidelines.

The objective of this study is to evaluate the methodological quality of Tuina clinical practice guidelines (CPGs). Computer searches of China National Knowledge Infrastructure (CNKI), Chinese Technical Periodicals (VIP), Wanfang Data Knowledge Service Platform, PubMed, Cochrane Library, Embase, and other databases were conducted to search for published guidelines on Tuina, with a search time frame from database creation to March 2021. Four evaluators independently used the Appraisal of Guidelines for Research and Evaluation II instrument to evaluate the quality of the included guidelines. A total of eight guidelines related to Tuina were included in this study. The quality of reporting was low in all included guidelines. The highest quality report had a total score of 404 and was rated as "highly recommended." The worst guideline had a final score of 241 and was rated as "not recommended." Overall, 25% of the included guidelines were recommended for clinical use, 37.5% were recommended after revision, and 37.5% were not recommended. The number of existing Tuina clinical practice guidelines is limited. The methodological quality is low, far from the internationally accepted clinical practice guideline development and reporting norms. In the future, reporting specifications of guidelines and the methodology of guideline development, including the rigor of the guideline development process, the clarity, application, and independence of reporting, should be emphasized in the development of the Tuina guidelines. These initiatives could improve the quality and applicability of clinical practice guidelines to guide and standardize the clinical practice of Tuina.

Molecular markers predicting the progression and prognosis of human papillomavirus-induced cervical lesions to cervical cancer.

Persistent Human Papillomavirus (HPV) infection is linked to 99% of cervical cancer (CC) cases. HPV types 16 and 18 aloneresult in 75% of CC cases and thus are considered to be high-risk types (HR-HPV). CC is thethird most common cancer among women globally. Approximately, 7000 patients die from it yearly. It is worthy to note that not every patient with HPV precancerous lesions will progress to CC. The objectives of this review is to explore the utilization ofmolecular and viral biomarkers asa tool for early detection and prediction of HPV-induced cervical lesions that might progress to CC. The data basesPubMed, Google Scholar, EBSCO were searched using keywords CC screening, HPV, and recent molecular biomarkers. The search time frame was within the last 7years. Studies on HPV-induced cancers other than CC were excluded; a total of 200 eligible articles were retrieved. In this review we explored the current literature about HPV virology, virulence genes and early diagnostic/prognostic molecular biomarkers in CC. The oncogenic property of HPV is attributed to viral expression of various early proteins (E5, E6, E7). The interaction between viral oncoproteins and the cellular genetic apparatus alters the expression of many genes at different phases of the disease. There was an association between cervical lesions induced by HR-HPV andtheoverexpression of markers of oxidative DNA damage and other proteins. The markersp16INK4a, programmed cell death-1 (PD-1)/programmed cell death ligand 1, mismatch repair enzymes (MMR), miRNA-377, claudin family (CLDN)are dysregulated and are associated with high risk lesions. Furthermore, advanced older cervical lesions were associated with high methylation levels and higherrisk to progress to CC. Adding differentthe abovemarkers to the CC screening program scheme might offera triage for prioritizing patient management.

Effects of different physical activity interventions on children with attention-deficit/hyperactivity disorder: A network meta-analysis of randomized controlled trials.

Previous studies have shown that physical activity interventions positively affect core symptoms and executive functioning in children with attention-deficit/hyperactivity disorder (ADHD). However, comparisons between different physical activity interventions still need to be made. This study is the first to analyze the effects of 10 different types of physical activity on children with ADHD through a network meta-analysis. PubMed, Embase, Web of Science, and Cochrane Library databases were searched for randomized controlled trials on the effects of physical activity interventions on children with ADHD. The search time frame was from database creation to October 2022. Two investigators independently performed literature screening, extraction, and quality assessment. Network meta-analysis was performed with Stata 15.1. A total of 31 studies were included, and the results indicated that perceptual-motor training was the most effective in terms of motor ability and working memory (SUCRA = 82.7 and 73.3%, respectively). For attention problems and cognitive flexibility, aquatic exercise was the most effective (SUCRA = 80.9 and 86.6%, respectively). For social problems, horsemanship was the most effective (SUCRA = 79.4%). For inhibition switching, cognitive-motor training was the most effective (SUCRA = 83.5%). Our study revealed that aquatic exercise and perceptual-motor training had a superior overall performance. However, the effects of various physical activity interventions on different indicators in children with ADHD can vary depending on the individual and the intervention's validity. To ensure an appropriate physical activity intervention is selected, it is important to assess the severity of symptoms exhibited by children with ADHD beforehand.

Titanium elastic nails vs locking plate in pediatric subtrochanteric femur fractures: A systematic review and meta-analysis.

Titanium elastic nails (TENs) and locking plates (LPs) are currently the main internal fixation for treating pediatric subtrochanteric femur fractures, and the optimal choice of internal fixation is controversial. This study aimed to systematically evaluate the effectiveness and safety of TENs and LPs in treating subtrochanteric fractures in children to provide a theoretical basis and reference for clinical treatment. The literature related to TENs and LPs for treating subtrochanteric fractures in children was searched using the CNKI, PubMed, Cochrane, Embase, and Web of Science, and the search time frame was from the establishment of the database to October 2022. Two evaluators screened the literature according to the inclusion and exclusion criteria and extracted relevant data. Meta-analysis was performed using Stata14.0 software. A total of 9 studies with 407 patients with subtrochanteric femur fractures were included in the final screening, including 210 cases with TENs and 197 cases with LPs. Meta-analysis results showed that compared with the locking plate, TEN had a shorter operative time [WMD = -1.3, 95%CI(-1.94,-0.66), p < 0.01], less intraoperative bleeding [WMD = -84.45, 95%CI(-111.09, -57.82), p < 0.01], shorter fracture healing time [WMD = -1.3, 95%CI(-1.94,-0.66), P < 0.01], shorter hospital stays [WMD = -2.80, 95% CI(-4.63,-0.98), p < 0.01], and earlier full weight bearing [SMD = -0.48, 95% CI(-0.91,-0.04), p < 0.05] but more intraoperative fluoroscopy [WMD = 28.23, 95% CI(15.22,41.25), p < 0.05]. The overall complication rate was high [OR = 3.52, 95% CI(1.96,6.34), p < 0.05], and the postoperative period was prone to angulation, rotation, and inversion deformity [OR = 3.68, 95% CI(1.40, 9.68), p < 0.05]. No significant difference in the incidence of lower limb inequality between the two types of internal fixation [OR = 0.83, 95% CI(0.38, 1.85), p > 0.05] and no significant difference in the Harris score of the hip at the last follow-up between the two types of internal fixation [WMD = -0.67, 95% CI(-2.01,0.67), p > 0.05] were found. In comparison to LPs, TENs have a shorter operation time, less intraoperative bleeding, and a shorter fracture healing time, and the child can be fully weight-bearing earlier. Locking plates can reduce the operator's x-ray exposure, and the incidence rate of postoperative angulation, rotation, and inversion deformity is low. Therefore, TENs and LPs are the best internal fixation methods for treating subtrochanteric fractures in children.

Relationship between COVID-19 infection and erectile dysfunction; a literature review examining the link and proposed mechanisms behind this phenomenon

It is now only in the wake of coronavirus disease 2019 (COVID-19) that we are beginning to understand many of the extra-respiratory manifestations of the condition. There is now growing evidence that erectile dysfunction (ED) is closely linked with the disease. We carry out one of the first literature reviews to consolidate the current evidence of the causal link between COVID-19 and ED and explore the proposed mechanisms that underpin this phenomenon. We carried out a literature search of the databases; PubMed (MEDLINE), Scopus, Web of Science and the Cochrane library. Search time frame was between December 2019 and March 2022. Only studies deemed of acceptable quality were included. Five studies were found highlighting the link between COVID-19 and ED. A further Nineteen studies were utilized to illustrate the proposed biological mechanisms underpinning COVID-19 related ED. Clear evidence has been documented through multiple studies internationally recognizing reduction in erectile scores and reduced sexual activity. It appears there is likely indirect and direct cytopathic effects on endothelial cells, in addition to hormonal and psychosocial factors. The associated ED is likely a result of a multitude of mechanisms including direct and indirect endothelial dysfunction, vasoactive cytokines, endocrine dysregulation, and psychosocial factors. This is the first literature review to delve into the likely underpinning mechanisms of the virus that drive ED.

Statin use improves the prognosis of ovarian cancer: An updated and comprehensive meta-analysis.

Statins are lipid-lowering agents that have also been found to have anticancer effects. The relationship between statin use and clinical outcomes in ovarian cancer (OC) remains controversial, as previous assessments of the relationship between statin use and OC prognosis have yielded inconsistent results. Therefore, a comprehensive meta-analysis was performed in the present study to investigate this association. Studies were systematically retrieved by searching the PubMed, Embase and Cochrane Library databases, and consulting reference lists of the related studies. The search timeframe was from database creation to September 1, 2022. Pooled hazard ratios (HRs) with corresponding 95% confidence intervals (CIs) were calculated to assess the association. In the present meta-analysis, 16 studies with 37,660 patients with OC were included, of which 11,296 patients had been prescribed statins. The results showed that statin use markedly improved the overall survival time (OS; HR, 0.79; 95% CI, 0.73-0.85; P<0.00001) and OC-specific survival time (HR, 0.84; 95% CI, 0.80-0.89; P<0.00001), especially the OS time in patients with serous OC (HR, 0.81; 95% CI, 0.74-0.89; P<0.0001) and endometrioid OC (HR, 0.80; 95% CI, 0.66-0.98; P=0.03). In addition, survival rate was higher in patients who used statins after OC diagnosis (HR, 0.79; 95% CI, 0.73-0.85; P<0.00001). However, there was no statistically significant association between statin use and the prognosis of mucinous and clear cell OC. The results suggested that statin use markedly improved the OS in patients with OC, including in those with serous and endometrioid OC. Statins were also found to improve the prognosis of patients of both Asian and non-Asian ethnicities. In addition, both lipophilic and hydrophilic statins improved the survival in patients with OC, especially in patients using statins after OC diagnosis. However, the effect may vary depending on the statin type, duration of use and cancer type, and more well-designed studies are needed to further evaluate this.

The added value of S-detect in the diagnostic accuracy of breast masses by senior and junior radiologist groups: a systematic review and meta-analysis.

S-detect is an emerging computer-aided diagnosis (CAD) technique that provides a reference for radiologists to identify breast cancer. Some studies have shown that US (ultrasound) + S-detect can improve the diagnostic accuracy of junior radiologists more than senior radiologists, but the results are inconsistent in various studies. Therefore, this meta-analysis aimed to assess the value of S-detect combined with the US outcomes from senior and junior radiologists for the diagnosis of breast cancer. We searched the PubMed, Cochrane Library, Embase, Web of Science, and Wanfang databases, China Biology Medicine disc, China National Knowledge Infrastructure (CNKI), and VIP database for trials on the diagnostic accuracy of US + S-detect for the diagnosis of breast masses. The search time frame was from the date of establishment of the database to August 20, 2022. Two researchers independently screened the literature, extracted the information, and evaluated the quality of the included literature using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) scale. StataSE 15.1 software was utilized to assess pooled metrics, including sensitivity, specificity, and the area under the curve (AUC). A total of 19 articles with 3,349 patients and 3,895 breast masses were included in this meta-analysis. Of these, seventeen articles evaluated the diagnostic performance of senior radiologists' US + S-detect for breast cancer, while twelve articles reported junior radiologists' diagnostic performance. The risk of bias was primarily attributed to patient selection, flow and timing. In the senior radiologist group, the pooled sensitivity and specificity of US + S-detect were 0.93 [95% confidence interval (CI): 0.89-0.95] and 0.86 (95% CI: 0.80-0.90), respectively, with an AUC of 0.96. As for the junior radiologist group, the pooled sensitivity and specificity of US + S-detect were 0.89 (95% CI: 0.83-0.93) and 0.79 (95% CI: 0.72-0.84), respectively, and the AUC was 0.91. The results of this meta-analysis showed that the pooled sensitivity and the AUC of both the senior and junior radiologist groups were high, with good diagnostic efficacy and high clinical application. However, the results of this study are highly heterogeneous and need to be validated by collecting more high-quality studies and accumulating a larger sample size.

The effectiveness and safety of three surgical procedures for the treatment for benign prostatic hyperplasia: A network meta-analysis

ObjectiveTo evaluate the effectiveness and safety of transurethral resection of the prostate (TURP), holmium laser enucleation of the prostate (HoLEP) and thulium laser enucleation of the prostate (ThuLEP) in the treatment of benign prostatic hyperplasia using a network Meta-analysis. MethodsRandomized controlled trials of TURP, HoLEP and ThuLEP for benign prostatic hyperplasia were collected by computerized searches of databases including CNKI, WANFANG, VIP, PubMed, The Cochrane Library, the Web of Science and Embase, with a search time frame of build to January 2022. The literature was screened and data was extracted by two investigators separately, while the risk of bias of the included studies was evaluated before systematic evaluation and network meta-analysis using ADDIS 1.16.8 software and RevMan 5.3 software. ResultsA total of 27 RCTs with a total of 3335 patients were involved. The results of the network meta-analysis showed that ThuLEP was better than the remaining two procedures in terms of enhancing patients' subjective perception and improving objective indicators, and the incidence of adverse events such as postoperative urethral stricture and urinary incontinence was lower compared with that of conventional TURP in both short- and long-term postoperative follow-ups. ConclusionAs ThuLEP is effective, safe, and featured with few postoperative complications, it can be the preferred surgical procedure for prostate enlargement. Nevertheless, because of the limited number of studies included, more-sample, multicenter, double-blind clinical randomized controlled trials are required in the future to further verify the findings of the present study.

A Systematic Review of Radio Frequency Threats in IoMT

In evolving technology, attacks on medical devices are optimized due to the driving force of AI, computer vision, mixed reality, and the internet of things (IoT). Optimizing cybersecurity on the internet of medical things (IoMT) and building cyber resiliency against crime-as-a-service (CaaS) in the healthcare ecosystem are challenging due to various attacks, including spectrum-level threats at the physical layer. Therefore, we conducted a systematic literature review to identify the research gaps and propose potential solutions to spectrum threats on IoMT devices. The purpose of this study is to provide an overview of the literature on wireless spectrum attacks. The papers we reviewed covered cyber impacts, layered attacks, attacks on protocols, sniffing attacks, field experimentation with cybersecurity testbeds, radiofrequency machine learning, and data collection. In the final section, we discuss future directions, including the sniffing attack mitigation framework in IoMT devices operating under a machine implantable communication system (MICS). To analyze the research papers about physical attacks against IoT in health care, we followed the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. Scopus, PubMed, and Web of Science were searched for peer-reviewed articles, and we conducted a thorough search using these resources. The search on Scopus containing the terms “jamming attack” and “health” yielded 330 rows, and the investigation on WoS yielded 17 rows. The search terms “replay attack” and “health” yielded 372 rows in Scopus, while PubMed yielded 23 rows, and WoS yielded 50 articles. The search terms “side-channel attack” and “health” yielded 447 rows in Scopus, WoS yielded 30 articles, and the search terms “sniffing attack” and “health” yielded 18 rows in Scopus, while PubMed yielded 1 row, and WoS yielded 0 articles. The terms “spoofing attack” and “health” yielded 316 rows in Scopus, while PubMed yielded 5 rows, and WoS yielded 23 articles. Finally, the search terms “tampering attack” and “health” yielded 25 rows in Scopus, PubMed yielded 14 rows, and WoS yielded 46 rows. The search time frame was from 2003 to June 2022. The findings show a research gap in sniffing, tampering, and replay attacks on the IoMT. We have listed the items that were included and excluded and provided a detailed summary of SLR. A thorough analysis of potential gaps has been identified, and the results are visualized for ease of understanding.

Re-evaluation of Mirror Visual Feedback Therapy for a Systematic Evaluation/Meta-analysis of Physical Function Re-education After Stroke.

The aim of the study is to re-evaluate the methodological quality and quality of evidence for a systematic evaluation/meta-analysis of the effect of mirror visual feedback therapy on physical function re-education after stroke. Systematic evaluations/meta-analyses of mirror visual feedback therapy on physical function re-education after stroke were searched in the China Knowledge Network database, Wanfang database, Vipers database, China Biomedical Literature database, PubMed, Web of Science, and Embase using a computer, and the search time frame was up to January 2022. Methodological quality and quality of evidence ratings of the included studies were determined using the AMSTAR2 scale and GRADE classification by two authors. Seventeen publications were included. The evaluation with the AMSTAR2 scale showed that one study had an intermediate quality rating, five had a low-quality rating, and the remaining 11 were all very low quality. The GRADE scale showed 93 outcome indicators, of which 6 were intermediate, 23 were low grades, and the rest were very low grades, with low overall quality. Mirror visual feedback therapy is efficacious for physical function re-education after stroke and promotes recovery from physical dysfunction, but the methodological quality and quality of evidence from the related systematic evaluations/meta-analyses are low.

Efficacy of Chinese Medicine Injection for Cardiotoxic Injury of Anthracycline Chemotherapy Drugs: A Network Meta-Analysis of Randomized Controlled Trials.

Background Chinese medicine injections (CMIs) are widely used in the prevention and treatment of cardiotoxicity caused by anthracycline chemotherapeutic drugs. However, it is uncertain that CMIs are more effective in combating the cardiotoxicity of anthracyclines. The aim of this Network Meta-analysis (NMA) was to compare the treatment effects of various CMIs in order to determine the best CMI for the prevention and treatment of cardiac damage from anthracyclines. Methods The Chinese Journal Full Text Database (CNKI), Wanfang Database, Chinese Science and Technology Journal Full Text Database (VIP), Chinese Biomedical Literature Database (CBM), PubMed, Web of Science, and Cochrane Library databases were searched to screen randomized controlled trials (RCTs) of CMIs against cardiotoxicity of anthracycline-based chemotherapeutic drugs. The search time frame was all from the establishment of the database to October 1, 2021. After independent screening of the literature, extraction of information and evaluation of the risk of bias of the included studies by two evaluators, mesh meta-analysis was performed using RevMan 5.3, Stata 15.1, and ADDIS 1.16.8 software. Results A total of 33 studies including 2783 patients, including 1410 cases in the experimental group and 1373 cases in the control group were included, and six CMIs were extracted, namely, Shenfu injection, Shenmai injection, Shenqi Fuzheng injection, Shengmai injection, Xinmailong injection, and Haungqi injection. The results of the reticulated meta-analysis showed that in terms of ST-T segment (ECG change) change rate, Haungqi injection, Shenfu injection, and Xinmailong injection were superior. In terms of lowering CK-MB, Huangqi Injection and Shenqi Fuzheng injection were superior. In terms of improving Left ventricular ejection fraction (LVEF), Shenfu injection, Huangqi Injection, and Shengmai injection were more effective than other injections. In terms of improving LVEDD, Shengmai injection, Huangqi Injection, and Xinmailong injection have advantages. Conclusion The six CMIs included in this study are effective against cardiotoxicity caused by anthracycline-based chemotherapeutic agents. Huangqi Injection and Shenfu injection are both superior in improving various outcome indicators. There is still a need for larger, high-quality randomized controlled trials (RCTs) to compare the various CMIs in a more refined way.

Cancer screening simulation models: a state of the art review

BackgroundNowadays, various simulation approaches for evaluation and decision making in cancer screening can be found in the literature. This paper presents an overview of approaches used to assess screening programs for breast, lung, colorectal, prostate, and cervical cancers. Our main objectives are to describe methodological approaches and trends for different cancer sites and study populations, and to evaluate quality of cancer screening simulation studies.MethodsA systematic literature search was performed in Medline, Web of Science, and Scopus databases. The search time frame was limited to 1999–2018 and 7101 studies were found. Of them, 621 studies met inclusion criteria, and 587 full-texts were retrieved, with 300 of the studies chosen for analysis. Finally, 263 full texts were used in the analysis (37 were excluded during the analysis). A descriptive and trend analysis of models was performed using a checklist created for the study.ResultsCurrently, the most common methodological approaches in modeling cancer screening were individual-level Markov models (34% of the publications) and cohort-level Markov models (41%). The most commonly evaluated cancer types were breast (25%) and colorectal (24%) cancer. Studies on cervical cancer evaluated screening and vaccination (18%) or screening only (13%). Most studies have been conducted for North American (42%) and European (39%) populations. The number of studies with high quality scores increased over time.ConclusionsOur findings suggest that future directions for cancer screening modelling include individual-level Markov models complemented by screening trial data, and further effort in model validation and data openness.

Construction of a Review About Epigenetics for Biology Teachers and Other Non-experts

Epigenetics, the new research field at the cutting edge of biology research, needs to be introduced in biology education. The aim of this review is to support biology teachers and other non-experts to get an overview of the field, as a review in epigenetics has hardly been written for these groups. This review was done by finding documents describing central features of epigenetics, increasing the understanding of epigenetics’ contribution to perspectives in society, and to be a model for a review in a rapidly developing science field. As an example of societal perspectives, the old dispute about “nature” or “nurture” is discussed, epigenetics focusing on the role of “nurture’s” influence on “nature.” Consequently, epigenetics dispels biological determinism. As this review was intended to fill a gap in the literature, a theoretical framework for the construction of the review had to be invented. This was done in an iterative process during the construction of the review. Documents were searched for in the databases of ERIC, Scopus, and Web of Science, peer-reviewed, and had been published by a well-renowned publisher. The search time frame was January 2016 to December 2019, including document types books and book chapters, plus journal articles for ERIC; documents had to be written in English and published as open access. Searches were divided into pre-defined categories based on a newly performed Delphi study. Exemplar studies, which best described each category, are discussed in the light of frontline research. As implications from epigenetics are important for a variety of areas within society, the review is a contribution to the field of sociology of science, aiming to support science education at the very front of science.

Dental care in health resort institutions

Addressing the HR rehabilitation in patients with various maxillofacial diseases for further consideration of the possibility of the increased use of HR care in dental practice. Russian and English-language publications were analyzed without specifying the search timeframe. The search keywords were the following: «health-resort care», «balneotherapy», «peloid therapy», «physiotherapy», «magnet therapy», «laser therapy» in combination with «dental diseases», «maxillofacial diseases», «periodontal diseases», «temporomandibular joint diseases», «postoperative rehabilitation» «balneotherapy», «mud therapy», «peloid therapy», «spa therapy», «physiotherapy». A total of 21 articles were analyzed, including 10 related to periodontal disease, 5 to temporomandibular joint pathology, and 6 to rehabilitation in the postoperative period. Seventeen original studies (3855 patients) were selected, including 47.62% with evidence level C, due to lack of information on comparison group or randomization. Available data from clinical studies suggest the effectiveness of natural and physiotherapeutic factors in the medical rehabilitation of patients with various dental diseases. Further randomized clinical trials and the development of clinical guidelines for various techniques in dental diseases are warranted.

Clinicopathological features of esophageal schwannomas in mainland China: systematic review of the literature.

Esophageal schwannoma (ES) are rare and mostly benign neurogenic tumors. The clinical misdiagnosis rate of it is high. In this study, the clinicopathologic features of ES in mainland China were studied to better understand the disease and improve the diagnosis and treatment rate. A systematic review was conducted in accordance with PRISMA guidelines. The keywords "esophageal schwannoma", "esophageal neurinoma" and "esophageal neurilemoma" were searched for databases such as Pubmed, EMbase, Wanfang Database and Chinese National Knowledge Infrastructure. The search time frame for database was until July 2019. Combined with our patient, the clinicopathological data and the diagnosis and treatment of ES were summarized. ES occurs in the upper part of the mediastinum and in the thoracic esophagus in most patients in the neck, upper and middle segments. CT and PET/CT examinations can be used for diagnosis, but the differentiation value of both benign and malignant ES is similar. The histopathological findings of forceps biopsy specimens are often difficult to diagnose, and deep tissue biopsies may increase pathological accuracy. EUS-FNA is also recommended for ES diagnosis, but it may also be misdiagnosed. Pathological features include a fusiform arrangement in a palisade-like structure or a tumor cell arranged in a network to form a loose structure. ES characteristic immunohistochemistry results showed that S-100 protein has strong immunological activity. The definitive diagnosis requires immunohistochemistry, especially immunological reaction with S-100 protein. The appropriate treatment plan should be selected according to the diameter of the lesion. The overall prognosis of ES is good, but attention should be paid to follow-up.

Protection Against Ionizing Radiation-Induced Normal Tissue Damage by Resveratrol: A Systematic Review.

The use of some agents as radioprotectors has been evaluated for protection against normal tissue toxicity following exposure to ionizing radiation. Resveratrol, a natural flavonoid, with antioxidant and anti-inflammatory properties has attracted research interests for its radioprotective potential. This study systematically evaluates existing studies to examine the radioprotective effectiveness of resveratrol. A literature search of the electronic databases, including PubMed, Scopus, and Embase was conducted to retrieve articles investigating the protective effect of resveratrol against ionizing radiation-induced damage to normal tissues. The search timeframe ranged from the inception of each database to January 2020. From an initial search of 231 articles, and after the removal of duplicates as well as applying the predetermined inclusion and exclusion criteria, 33 articles were finally included for this systematic review. Results showed promising protective effect of resveratrol against ionizing radiation-induced damage to normal tissues. Furthermore, no adverse effect was observed after administering resveratrol. Resveratrol showed the potential to protect against ionizing radiation-induced damage to normal tissue cells via notable mechanisms, including anti-apoptotic and anti-inflammatory effects. However, further studies on the efficacy of clinical translation of resveratrol would open up more insights, while other gray areas such as the optimal radioprotective dosage of resveratrol requires further investigation. Overall, resveratrol is a potential double-edged sword in cancer therapy while protecting healthy tissues.

The relative risk of developing type 2 diabetes among individuals with prediabetes compared with individuals with normoglycaemia: Meta-analysis and meta-regression.

To assess the overall relative risk of diabetes in individuals with prediabetes based on updated diagnostic criteria, as compared with individuals with normoglycaemia; and to identify the study characteristics associated with the heterogeneity between studies. Meta-analysis, meta-regression. PubMed, CINAHL, British Nursing Index. Search time frame: December 1998-December 2018. The pooled relative risk of developing diabetes among individuals with prediabetes compared with those with normoglycaemia was calculated under a random effects model. Studies reported the natural progression from prediabetes to diabetes were included in this review. Sources of study heterogeneity were examined by a meta-regression. Fifty-nine eligible studies were systematically identified. The pooled relative risk for diabetes among individuals with prediabetes as compared with normoglycaemia was 5.88 (95% CI: 5.02-6.89). The annualized incidence rate (per 1,000 person-year) for diabetes among individuals with prediabetes defined by different criteria varied from 2.20-212.15, with high heterogeneity between studies (I2 =96.64%, Q test: p<.001). In the multivariable meta-regression analysis, Asian population significantly increased RR compare to Caucasians. Besides, people with 'elevated glycated haemoglobin A1c or impaired fasting glucose' had highest relative risk compare to people with other types of prediabetes. Individuals with prediabetes had higher risk of developing diabetes than those with normoglycaemia. Races and diagnostic criteria of prediabetes were associated with the magnitude of the estimated risk. Prediabetes is a precursor of diabetes. To screen people with prediabetes as early as possible, practitioners could consider haemoglobin A1c test as an alternative to fasting plasma glucose test. Nurses should educate people especially Asians with prediabetes for the prevention of progression to diabetes.
