The Mechanism of Action between Pulsed Radiofrequency and Orthobiologics: Is There a Synergistic Effect?

Radiofrequency energy is a common treatment modality for chronic pain. While there are different forms of radiofrequency-based therapeutics, the common concept is the generation of an electromagnetic field in the applied area, that can result in neuromodulation (pulsed radiofrequency—PRF) or ablation. Our specific focus relates to PRF due to the possibility of modulation that is in accordance with the mechanisms of action of orthobiologics. The proposed mechanism of action of PRF pertaining to pain relief relies on a decrease in pro-inflammatory cytokines, an increase in cytosolic calcium concentration, a general effect on the immune system, and a reduction in the formation of free radical molecules. The primary known properties of orthobiologics constitute the release of growth factors, a stimulus for endogenous repair, analgesia, and improvement of the function of the injured area. In this review, we described the mechanism of action of both treatments and pertinent scientific references to the use of the combination of PRF and orthobiologics. Our hypothesis is a synergic effect with the combination of both techniques which could benefit patients and improve the life quality.

Towards optimum smoking cessation interventions during pregnancy: a household model to explore cost-effectiveness

BACKGROUND AND AIMS

Previous economic evaluations of smoking cessation interventions for pregnant women are limited to single components, which do not in isolation offer sufficient potential impact to address smoking cessation targets. To inform the development of more appropriate complex interventions, we (1) describe the development of the Economics of Smoking in Pregnancy: Household (ESIP.H) model for estimating the life-time cost-effectiveness of smoking cessation interventions aimed at pregnant women and (2) use a hypothetical case study to demonstrate how ESIP.H can be used to identify the characteristics of optimum smoking cessation interventions.

METHODS

The hypothetical intervention was based on current evidence relating to component elements, including financial incentives, partner smoking, intensive behaviour change support, cigarettes consumption and duration of support to 12 months post-partum. ESIP.H was developed to assess the life-time health and cost impacts of multi-component interventions compared with standard National Health Service (NHS) care in England. ESIP.H considers cigarette consumption, partner smoking and some health conditions (e.g. obesity) that were not included in previous models. The Markov model's parameters were estimated based on published literature, expert judgement and evidence-based assumptions. The hypothetical intervention was evaluated from an NHS perspective.

RESULTS

The hypothetical intervention was associated with an incremental gain in quitters (mother and partner) at 12 months postpartum of 249 [95% confidence interval (CI) = 195-304] per 1000 pregnant smokers. Over the long-term, it had an incremental negative cost of £193 (CI = -£779 to 344) and it improved health, with a 0.50 (CI = 0.36-0.69) increase in quality-adjusted life years (QALYs) for mothers, partners and offspring, with a 100% probability of being cost-effective.

CONCLUSIONS

The Economics of Smoking in Pregnancy: Household model for estimating cost-effectiveness of smoking cessation interventions aimed at pregnant women found that a hypothetical smoking cessation intervention would greatly extend reach, reduce smoking and be cost-effective.

Premenstrual exacerbation of mental health disorders: a systematic review of prospective studies

Mental health disorders can be exacerbated during periods of hormonal fluctuation (e.g. pregnancy, menopause), and the risk factors for sensitivity to these fluctuations are similar to those of mental disorders (e.g. trauma). However, the extent to which hormonal fluctuations during the menstrual cycle impact symptoms of preexisting mental disorders remains unclear. Prospective methodology is considered the gold standard for measuring symptoms across the menstrual cycle. Thus, the aim of the review was to address this knowledge gap by summarising all available studies prospectively measuring symptoms of mental disorders across the menstrual cycle. A systematic review with narrative synthesis was conducted; meta-analysis was precluded due to methodological heterogeneity of included studies. Electronic databases MEDLINE, Embase, PyschINFO and CINAHL were systematically searched from inception. Risk of bias for individual studies was assessed using a modified version of the Newcastle-Ottawa Scale. The search identified 629 studies from which 35 met inclusion criteria. There was clear evidence of symptom exacerbation during the perimenstrual phase for psychotic disorders, panic disorder, eating disorders, depression and borderline personality disorder. Less consistent evidence was found for anxiety, and a different pattern of symptom exacerbation was observed in bipolar disorder. Sample size and methodology varied considerably amongst studies. Overall, there was mixed evidence for perimenstrual exacerbation across mental disorders, which could be partly explained by methodological limitations of the studies. However, hormonal fluctuations during the menstrual cycle may exacerbate psychiatric symptoms in a subgroup of individuals who are hormone sensitive.

Rates and Patterns of Australian Emergency Department Presentations of People Who Use Stimulants: A Systematic Literature Review

The use of illicit stimulants continues to pose a significant challenge to different health sectors. In Australia, four particular stimulants, namely amphetamines and their derivatives, methamphetamine, ecstasy or 3,4-methylenedioxy-methamphetamine (MDMA), and cocaine cause a significant challenge to EDs as managing patients who use stimulants can be labor and resource intensive. While Australian data are available for stimulant-related ambulance attendances and hospitalizations, little is known about ED presentations of people who use stimulants. The aim of this paper is to systematically review the available literature related to the rates and patterns of ED presentations of people who use stimulants in Australia. A search was conducted on EBSCOhost, CINAHL Complete, and PubMed databases, as well as Google Scholar. Search terms consisted of combinations of the following terms: 1) stimulant AND ED AND Australia; 2) stimulants AND emergency presentations OR accident and emergency AND Australia, 3) amphetamine OR methamphetamine OR ecstasy OR cocaine AND ED AND Australia. Articles that met the inclusion criteria were included in the review and subjected to a quality appraisal. Data were extracted from the selected papers, including patient demographics, presentation rates, type of stimulant, reasons for presentations, police or ambulance service involvement, comorbidities, mental health issues, triage codes, admissions, and separations. The results of the review are reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies were eligible if they were English-language peer-reviewed articles published between January 2011 and December 2021 and if they included data on Australian ED presentations of people who use non-prescription illicit stimulants. Studies were excluded if they did not include stimulant-related ED presentations or focused on ED presentations related to prescription stimulants, including Ritalin and Adderall, non-stimulant drugs, or caffeine for attention deficit disorder (ADD) or attention-deficit hyperactivity disorder (ADHD). The selected articles were appraised for quality, rigor, and risk of bias by two authors. The studies were assessed using the Newcastle Ottawa Scale (NOS) for cross-sectional, cohort, and case-control studies depending on the methodology identified in the study. A total of 19 articles were included in this study. Males represented 53 to 85% of ED presentations of people who use stimulants with an age range of 0 to 65 and are more likely to be transported by police or ambulance. People who use stimulants presented to EDs with varying psychological and behavioral concerns such as psychosis, self-harm, suicidal ideations, hallucinations, agitations, and aggressiveness, as well as medical conditions, including heart palpitations, nausea and vomiting, and significant physical injuries.

Androgen receptor functions in pericentral hepatocytes to decrease gluconeogenesis and avoid hyperglycemia and obesity in male mice

BACKGROUND

Although the impact of hepatic androgen receptor (AR) pathway on liver pathogenesis was documented, its physiological function in normal liver is remained unclear. This study aims to investigate if hepatic AR acts on metabolism, the major liver function, using a hepatic-specific AR-transgenic (H-ARTG) mouse model.

METHODS

We established the albumin promoter driven H-ARTG mice and included wild type (WT) and H-ARKO mice for study. The body weight, specific metabolic parameters and results from various tolerance tests were compared in different groups of mice fed a chow diet, from 2 to 18 months of age. Glucose feeding and insulin treatment were used to study the expression and zonal distribution pattern of AR and related genes in liver at different prandial stages.

RESULTS

The body weight of H-ARTG mice fed a chow diet was 15 % lower than that of wild-type mice, preceded by lower blood glucose and liver triglyceride levels caused by AR reduced hepatic gluconeogenesis. The opposite phenotypes identified in H-ARKO and castrated H-ARTG mice support the critical role of activated AR in decreasing gluconeogenesis and triglyceride levels in liver. Hepatic AR acting by enhancing the expression of cytosolic glycerol-3-phosphate dehydrogenase (cGPDH), a key of glycerophosphate shuttle, was identified as one mechanism to decrease gluconeogenesis from glycerol. We further found AR normally expressed in zone 3 of hepatic lobules. Its level fluctuates dependent on the demand of glucose, decreased by fasting but increased by glucose uptake or insulin stimulation.

CONCLUSION

AR is a newly identified zone 3 hepatic gene with function in reducing blood glucose and body weight in mice. It suggests that stabilization of hepatic AR is a new direction to prevent hyperglycemia, obesity and nonalcoholic fatty liver disease (NAFLD) in males.

Impact of pulmonary embolism response teams on acute pulmonary embolism: a systematic review and meta-analysis

BACKGROUND

The impact of pulmonary embolism response teams (PERTs) on treatment choice and outcomes of patients with acute pulmonary embolism (PE) is still uncertain.

OBJECTIVE

To determine the effect of PERTs in the management and outcomes of patients with PE.

METHODS

PubMed, Embase, Web of Science, CINAHL, WorldWideScience and MedRxiv were searched for original articles reporting PERT patient outcomes from 2009. Data were analysed using a random effects model.

RESULTS

16 studies comprising 3827 PERT patients and 3967 controls met inclusion criteria. The PERT group had more patients with intermediate and high-risk PE (66.2%) compared to the control group (48.5%). Meta-analysis demonstrated an increased risk of catheter-directed interventions, systemic thrombolysis and surgical embolectomy (odds ratio (OR) 2.10, 95% confidence interval (CI) 1.74-2.53; p<0.01), similar bleeding complications (OR 1.10, 95% CI 0.88-1.37) and decreased utilisation of inferior vena cava (IVC) filters (OR 0.71, 95% CI 0.58-0.88; p<0.01) in the PERT group. Furthermore, there was a nonsignificant trend towards decreased mortality (OR 0.87, 95% CI 0.71-1.07; p=0.19) with PERTs.

CONCLUSIONS

The PERT group showed an increased use of advanced therapies and a decreased utilisation of IVC filters. This was not associated with increased bleeding. Despite comprising more severe PE patients, there was a trend towards lower mortality in the PERT group.

Liver Stiffness Is Associated with the Burden of Carotid and Systemic Atherosclerosis in an Unorganized Cohort of Patients 40-64 Years Old

Background: The aim of the study is to research the relationship between the severity of liver fibrosis and the burden of carotid and systemic atherosclerosis. Methods: The study includes 163 patients 40 to 64 years of age without atherosclerotic CVD or liver disease. All patients underwent duplex scanning of the carotid and lower limb arteries. All patients underwent transient liver elastometry using the FibroScan (Echosens, France). Results: Carotid plaque was detected in 110 (67.5%) patients. Based on the results of linear regression analysis, relationships between liver stiffness and carotid total plaque area (r = 0.21; p = 0.025) were found. Significant relationships were established between liver stiffness and atherosclerosis burden score based on the results of linear regression (r = 0.17; p = 0.029). Liver stiffness showed moderate diagnostic performance (AUC 0.666; p = 0.01) with regard to generalized atherosclerosis. An increase in liver stiffness >4.5 kPa was associated with an odds ratio of generalized atherosclerosis of 3.48 (95% CI 1.07−11.3; p = 0.038) after adjusting confounding factors. Conclusion: Among patients 40−64 years of age without established atherosclerotic CVD and liver disease, liver stiffness directly correlates with the burden of carotid and systemic atherosclerosis. Liver stiffness showed moderate diagnostic performance (AUC 0.666; p = 0.01) with regard to generalized atherosclerosis.

Magnitude of postpartum hemorrhage and associated factors among women who gave birth in Ethiopia: a systematic review and meta-analysis

Background

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality and morbidity worldwide, particularly in resource-limited countries such as Ethiopia. Findings from a few studies were inconsistent and inconclusive. Therefore, this study aimed to estimates the pooled magnitude of PPH and factors associated with PPH among women who gave birth in Ethiopia.

Methods

Electronic databases such as Medline, Pub Med, Cochrane library, the Web of Science, and Google Scholar were used to search for articles. The search period for articles was conducted from 15th August 2021 to 15th November 2021. Data were extracted using a standardized data extraction checklist and the analyses were conducted using Stata version 14. The Cochrane Q test statistic and I² statistics were used to assessing heterogeneity. To estimate the pooled magnitude of postpartum hemorrhage, a random-effects model was fitted. Association between PPH and independent variables was reported in odds ratio (OR) with 95% confidence interval (CI). Visual assessment of publication bias was assessed using a funnel plot and Egger’s test was used to check the significant presence of publication bias.

Results

A total of 876 studies were identified from several databases and nine studies fulfilled eligibility criteria and were included in the meta-analysis. The pooled magnitude of PPH in Ethiopia was 11.14% (95% CI 7.21, 15.07). The current meta-analysis revealed that lack of antenatal care follow-up (ANC) (OR = 6.52, 95% CI 2.87, 14.81), being multipara (OR = 1.88, 95% CI 1.25, 2.85), and having the previous history of PPH (OR = 7.59, 95% CI 1.88, 30.55) were found to be significantly associated with PPH.

Conclusion

In Ethiopia the magnitude of PPH was high, and lack of ANC up follow-up, being multipara, and having a previous history of PPH were risk factors for postpartum hemorrhage. Thus, improving antenatal care follow-up is needed to decrease the magnitude of postpartum hemorrhage.

Gradual Drug Release Membranes and Films Used for the Treatment of Periodontal Disease

Periodontitis is an inflammatory disease that, if not treated, can cause a lot of harm to the oral cavity, to the patients' quality of life, and to the entire community. There is no predictable standardized treatment for periodontitis, but there have been many attempts, using antibiotics, tissue regeneration techniques, dental scaling, or root planning. Due to the limits of the above-mentioned treatment, the future seems to be local drug delivery systems, which could gradually release antibiotics and tissue regeneration inducers at the same time. Local gradual release of antibiotics proved to be more efficient than systemic administration. In this review, we have made a literature search to identify the articles related to this topic and to find out which carriers have been tested for drug release as an adjuvant in the treatment of periodontitis. Considering the inclusion and exclusion criteria, 12 articles were chosen to be part of this review. The selected articles indicated that the drug-releasing carriers in periodontitis treatment were membranes and films fabricated from different types of materials and through various methods. Some of the drugs released by the films and membranes in the selected articles include doxycycline, tetracycline, metronidazole, levofloxacin, and minocycline, all used with good outcome regarding their bactericide effect; BMP-2, Zinc-hydroxyapatite nanoparticles with regenerative effect. The conclusion derived from the selected studies was that gradual drug release in the periodontal pockets is a promising strategy as an adjuvant for the treatment of periodontal disease.

Systematic Review and Meta-Analysis on the Role of Perioperative Blood Transfusion in Patients Undergoing Radical Cystectomy for Urothelial Carcinoma

BACKGROUND

Radical cystectomy (RC) is the standard of care in patients with muscle-invasive bladder cancer. The impact of perioperative red blood cell (RBC) transfusion on oncological outcomes after RC is not clearly established as the existing publications show conflicting results.

OBJECTIVES

The aim of this systematic review and meta-analysis was to investigate the prognostic role of perioperative RBC transfusion on oncological outcomes after RC.

METHODS

Systematic online search on PubMed was conducted, based on PRISMA criteria for publications reporting on RBC transfusion during RC. Publications with the following criteria were included: (I) reported data on perioperative blood transfusion; (II) Reported Hazard ratio (HR) and 95% -confidence interval (CI) for the impact of transfusion on survival outcomes. Primary outcome was the impact of perioperative RBC transfusion on recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). Risk of bias assessment was performed using Newcastle-Ottawa Scale. Statistical analysis was performed using Revman 5.4 software.

RESULTS

From 27 primarily identified publications, 19 eligible articles including 22897 patients were selected. Perioperative RBC transfusion showed no impact on RFS (Z = 1.34; p = 0,18) and significant negative impact on CSS (Z = 2.67; p = 0.008) and OS (Z = 3.22; p = 0.001). Intraoperative RBC transfusion showed no impact on RFS (Z = 0.58; p = 0.56) and CSS (Z = 1.06; p = 0.29) and OS (Z = 1.47; p = 0.14).Postoperative RBC transfusion showed non-significant trend towards improved RFS (Z = 1.89; p = 0.06) and no impact on CSS (Z = 1.56; p = 0.12) and OS (Z = 0.53 p = 0.60).

CONCLUSION

In this meta-analysis, we found perioperative blood transfusion to be a significant predictor only for worse CSS and OS but not for RFS. This effect may be determined by differences in tumor stages and patient comorbidities for which this meta-analysis cannot control due to lack of respective raw data.

Estimation of Behavioral Addiction Prevalence During COVID-19 Pandemic: A Systematic Review and Meta-analysis

Purpose of Review

The COVID-19 pandemic changed people’s lifestyles and such changed lifestyles included the potential of increasing addictive behaviors. The present systematic review and meta-analysis aimed to estimate the prevalence of different behavioral addictions (i.e., internet addiction, smartphone addiction, gaming addiction, social media addiction, food addiction, exercise addiction, gambling addiction, and shopping addiction) both overall and separately.

Recent Findings

Four databases (PubMed, Scopus, ISI Web of Knowledge, and ProQuest) were searched. Peer-reviewed papers published in English between December 2019 and July 2022 were reviewed and analyzed. Search terms were selected using PECO-S criteria: population (no limitation in participants’ characteristics), exposure (COVID-19 pandemic), comparison (healthy populations), outcome (frequency or prevalence of behavioral addiction), and study design (observational study). A total of 94 studies with 237,657 participants from 40 different countries (mean age 25.02 years; 57.41% females). The overall prevalence of behavioral addiction irrespective of addiction type (after correcting for publication bias) was 11.1% (95% CI: 5.4 to 16.8%). The prevalence rates for each separate behavioral addiction (after correcting for publication bias) were 10.6% for internet addiction, 30.7% for smartphone addiction, 5.3% for gaming addiction, 15.1% for social media addiction, 21% for food addiction, 9.4% for sex addiction, 7% for exercise addiction, 7.2% for gambling addiction, and 7.2% for shopping addiction. In the lockdown periods, prevalence of food addiction, gaming addiction, and social media addiction was higher compared to non-lockdown periods. Smartphone and social media addiction was associated with methodological quality of studies (i.e., the higher the risk of boas, the higher the prevalence rate). Other associated factors of social media addiction were the percentage of female participants, mean age of participants, percentage of individuals using the internet in country, and developing status of country. The percentage of individuals in the population using the internet was associated with all the prevalence of behavioral addiction overall and the prevalence of sex addiction and gambling addiction. Gaming addiction prevalence was associated with data collection method (online vs. other methods) that is gaming addiction prevalence was much lower using online methods to collect the data.

Summary

Behavioral addictions appeared to be potential health issues during the COVID-19 pandemic. Healthcare providers and government authorities should foster some campaigns that assist people in coping with stress during COVID-19 pandemics to prevent them from developing behavioral addictions during COVID-19 and subsequent pandemics.

Predictors of Poor Neonatal Outcomes among Pregnant Women in Indonesia: A Systematic Review and Meta-Analysis

OBJECTIVES

This study aimed to examine the association between maternal health behaviors and neonatal outcomes among the Indonesian population.

METHODS

Articles were collected from PubMed, EBSCO, ProQuest, DOAJ, and GARUDA. Funnel plots and Egger's tests analyzed indications of publication bias. A Mantel-Haenszel random-effects model was used to see the overall effect size of exposures on outcomes. Heterogeneity was seen based on I2. Data collected from articles included the author, year of publication, location of the study, study design, number of samples, risk factors, and effect sizes.

RESULTS

We identified 24 relevant studies, including eight from the primary databases and 16 from an additional database. A total of 12 studies were included in the meta-analysis, examining the association between maternal health behaviors and neonatal outcomes. The pooled odds ratio (OR) for passive smoking and low-birth-weight (LBW) was 3.41 (95% CI: 1.75-6.63, I2 = 40%, four studies). The pooled OR for incomplete antenatal care (ANC) and LBW was 6.29 (95% CI: 2.11-18.82, I2 = 70%, four studies). The pooled OR for incomplete ANC and neonatal mortality was 2.59 (95% CI: 1.01-6.66, I2 = 93%, four studies).

CONCLUSIONS

The results indicated that pregnant women with incomplete ANC had a higher risk of LBW and neonatal mortality, and those who were passively exposed to smoking had a higher risk of LBW. Further investigations are needed, considering the high heterogeneity found, and additional meta-analyses should be based on the variations of socio-demographic conditions.

Prevalence of burnout in medical students: A systematic review and meta-analysis

BACKGROUND

Medical students are at a significant risk of experiencing psychological issues, such as burnout. Over the past few years, more studies have been conducted on this topic, producing different results.

AIMS

The purpose of this review was to determine the global pooled prevalence rate and risk factors associated with burnout and its components among undergraduate (pre-intern) medical students.

METHOD

From inception until 30 November 2021, nine electronic databases were used for an electronic search. Using random-effects meta-analysis, we pooled the estimates using the DerSimonian-Laird method. The prevalence of burnout in medical students was the primary outcome of interest. Data were analyzed globally, by country, by research measure. Age and sex were examined as confounders using meta-regression analysis.

RESULTS

A random-effects meta-analysis of 42 studies involving 26,824 evaluating the prevalence of burnout in medical students showed an overall prevalence rate 37.23% [32.66%; 42.05%], Q = 2,267.15(41), p < .0001, τ² = .42, τ = .65, I² = 98.2%; H = 7.5. Prevalence of emotional exhaustion, depersonalization, and personal accomplishment were 38.08% [30.67%; 46.10%], 35.07% [26.74%; 44.41%], and 37.23% [32.66%; 42.05%], respectively. Variations were observed between countries and research measures. Age (older) and sex (female) were both significant predictors of burnout.

CONCLUSION

The prevalence of burnout in medical students was estimated to be 37.23%. It is urgent that future studies serve as a basis for the development of prevention and treatment programs to prevent and treat burnout in students.

Determinants of adolescents' contraceptive uptake in Ethiopia: a systematic review of literature

Introduction

Various studies have identified different factors that affect adolescent contraceptive uptake in different parts of Ethiopia. However, varying results were reported across primary studies and those results need to be systematically collated to inform policies. Therefore, this systematic review aimed to synthesize the findings of those primary studies to obtain more robust and representative evidence about adolescent contraceptive uptake in Ethiopia.

Methods

Five databases (MEDLINE via PubMed, Google Scholar, Scopus, Science Direct and CINAHL) were searched for papers published from January 2000 up to June 2021 in English. We limited our search to start on January 2000 as the health of adolescents have been given more attention after this period and to avoid time-lapsed biases. Seven studies were included in this systematic review. We used the Newcastle-Ottawa Scale and the Mixed Methods Appraisal Tool for quality assessment of the selected studies.

Results

Determinants of adolescent contraceptive utilization were focused on four levels: individual, socio-cultural, healthcare service and knowledge related factors. Individual-related factors that influence adolescents’ contraceptive uptake include; being in the age group of 10–15 years, not currently enrolled in school and being from low-income families, while socio-cultural factors include: lack of discussion with family members, arranged marriage, pressure from a partner, harmful traditional practices, discussion with peer groups and sexual partners. Healthcare service-related factors include; lack of information about contraceptives during health facility visits, lack of privacy during service provision and inconvenient service hours at health facilities, and not visiting health facilities, whereas, knowledge related factors include; having knowledge of contraceptive methods and being heard about contraceptives from media. Also, the proportion of adolescent contraceptive uptake ranged from 12 to 79%.

Conclusions

In this systematic, individual, socio-cultural, health-care-related, and knowledge-related characteristics have all been identified as influencing adolescents’ contraceptive uptake in Ethiopia. Hence, integrated interventions aimed at overcoming barriers to adolescent contraceptive uptake would be beneficial to improving adolescent contraceptive utilization in Ethiopia.

Clinical Efficacy, Survival, and Adverse Reaction Evaluation of Immune Checkpoint Inhibitor in Advanced Gastric Cancer: A Systematic Review and Meta-Analysis

Objective

To systematically assess the clinical effect and survival time of immune checkpoint inhibitor (ICIs) in advanced gastric cancer (GC) and adverse reactions to provide evidence-based medicine for its enhancement and adoption.

Methods

PubMed, EMBASE, ScienceDirect, Cochrane Library, China Knowledge Network database (CNKI), China VIP database, Wanfang database, and China Biomedical Literature Database (CBM) online database were searched for randomized controlled trials (RCT) of immuno-checkpoint inhibitors in advanced GC therapy. Retrieval time was limited to the period from the date the database was established to present. Separately, two researchers gathered the data. Statistical software RevMan5.4 was used to estimate bias risk according to the Cochrane Handbook 5.3 standard.

Results

The computer database retrieved 1723 articles, and 465 articles were eliminated when repeated studies were removed. After screening the titles and abstracts of 287 articles, 124 articles were contained after eliminating irrelevant studies, reviews, case reports, and no control literature. After carefully reading 108 studies with insufficient data and no major outcome markers, 6 RCTs were eventually contained. 4 articles compared the levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 199 (CA199) after treatment. The result indicated that the levels of serum CEA and CA199 in the study group were notably lower, and the difference was statistically significant (P < 0.05). The immune function indexes after treatment were compared, suggesting that the improvement of immune function indexes in the study group was notably better, and the difference was statistically significant (P < 0.05). Three clinical trials reported the median progression-free survival (PFS). The PFS of the study group was notably longer after treatment, and the difference was statistically significant (P < 0.05). The occurrence of adverse reactions after treatment was analyzed by meat, and all the literatures were analyzed. No notable differences were observed in the incidence of adverse reactions.

Conclusion

ICIs associated with chemotherapy is effective when treating GC, which can effectively promote the disease control rate of patients, enhance immune function, reduce the level of tumor markers, and prolong survival time. The safety is controllable, which is worth popularizing in clinical practice. However, more studies and follow-up with higher methodological quality and longer intervention time are needed to further verify it.

From Dukes-MAC Staging System to Molecular Classification: Evolving Concepts in Colorectal Cancer

This historical review aimed to summarize the main changes that colorectal carcinoma (CRC) staging systems suffered over time, starting from the creation of the classical Duke's classification, modified Astler-Coller staging, internationally used TNM (T-primary tumor, N-regional lymph nodes' status, M-distant metastases) staging system, and ending with molecular classifications and epithelial-mesenchymal transition (EMT) concept. Besides currently used staging parameters, this paper briefly presents the author's contribution in creating an immunohistochemical (IHC)-based molecular classification of CRC. It refers to the identification of three molecular groups of CRCs (epithelial, mesenchymal and hybrid) based on the IHC markers E-cadherin, β-catenin, maspin, and vimentin. Maspin is a novel IHC antibody helpful for tumor budding assessment, which role depends on its subcellular localization (cytoplasm vs. nuclei). The long road of updating the staging criteria for CRC has not come to an end. The newest prognostic biomarkers, aimed to be included in the molecular classifications, exert predictive roles, and become more and more important for targeted therapy decisions.

Current standard values of health utility scores for evaluating cost-effectiveness in liver disease: A meta-analysis

BACKGROUND

Health utility assessments have been developed for various conditions, including chronic liver disease. Health utility scores are required for socio-economic evaluations, which can aid the distribution of national budgets. However, the standard health utility assessment scores for specific health conditions are largely unknown.

AIM

To summarize the health utility scores, including the EuroQOL 5-dimensions 5-levels (EQ-5D-5L), EuroQol-visual analogue scale, short from-36 (SF-36), RAND-36, and Health Utilities Index (HUI)-Mark2/Mark3 scores, for the normal population and chronic liver disease patients.

METHODS

A systematic literature search of PubMed and MEDLINE, including the Cochrane Library, was performed. Meta-analysis was performed using the RevMan software. Multiple means and standard deviations were combined using the StatsToDo online web program.

RESULTS

The EQ-5D-5L and SF-36 can be used for health utility evaluations during antiviral therapy for hepatitis C. HUI-Mark2/Mark3 indicated that the health utility scores of hepatitis B patients are roughly 30% better than those of hepatitis C patients.

CONCLUSION

The EQ-5D-5L is the most popular questionnaire for health utility assessments. Health assessments that allow free registration would be useful for evaluating health utility in patients with liver disease.

Reducing systematic review burden using Deduklick: a novel, automated, reliable, and explainable deduplication algorithm to foster medical research

BACKGROUND

Identifying and removing reference duplicates when conducting systematic reviews (SRs) remain a major, time-consuming issue for authors who manually check for duplicates using built-in features in citation managers. To address issues related to manual deduplication, we developed an automated, efficient, and rapid artificial intelligence-based algorithm named Deduklick. Deduklick combines natural language processing algorithms with a set of rules created by expert information specialists.

METHODS

Deduklick's deduplication uses a multistep algorithm of data normalization, calculates a similarity score, and identifies unique and duplicate references based on metadata fields, such as title, authors, journal, DOI, year, issue, volume, and page number range. We measured and compared Deduklick's capacity to accurately detect duplicates with the information specialists' standard, manual duplicate removal process using EndNote on eight existing heterogeneous datasets. Using a sensitivity analysis, we manually cross-compared the efficiency and noise of both methods.

DISCUSSION

Deduklick achieved average recall of 99.51%, average precision of 100.00%, and average F1 score of 99.75%. In contrast, the manual deduplication process achieved average recall of 88.65%, average precision of 99.95%, and average F1 score of 91.98%. Deduklick achieved equal to higher expert-level performance on duplicate removal. It also preserved high metadata quality and drastically reduced time spent on analysis. Deduklick represents an efficient, transparent, ergonomic, and time-saving solution for identifying and removing duplicates in SRs searches. Deduklick could therefore simplify SRs production and represent important advantages for scientists, including saving time, increasing accuracy, reducing costs, and contributing to quality SRs.

Adolescents’ Contraceptive Uptake in Ethiopia: A Meta-Analysis

Introduction. Ethiopia has made significant efforts to enhance family planning services despite variations in the community’s use of modern contraception in different parts of the country. Various studies have reported the proportion and determinant factors of adolescents’ contraceptive uptake in Ethiopia. These studies are not consistent in terms of size, scope, and geographic coverage, and the results need to be systematically collated to inform policies. Therefore, this review was aimed at analyzing the findings of those primary studies to obtain more representative evidence of adolescents’ contraceptive uptake in Ethiopia. Methods. Five databases (MEDLINE via PubMed, Google Scholar, Scopus, ScienceDirect, and CINAHL) were searched for papers published from January 2000 up to June 2022 in English. Of thirty eligible studies, eight papers were included in this meta-analysis. Between-study heterogeneity was evaluated by the forest plot and inconsistency index ( $I^2$ ). A random-effects model was used to calculate the pooled estimates of adolescents’ contraceptive uptake. Results. The overall pooled proportion of adolescents’ contraceptive uptake was 40% ( $I^2=99.70$ , $p\le 0.001$ ; $95\%\text{CI}=19,61$ ). Adolescents’ usage of contraception was influenced by a number of factors: individual-, sociocultural-, knowledge- (about contraceptive methods), and healthcare service-related factors. Individual-related factors include the educational status of adolescents, being of young age, and the income status of adolescents’ families. Sociocultural-related factors comprise discussion with the family/relatives, parent disapproval and pressure from partners, and being married or having a partner. Healthcare service-related factors include the availability of youth clubs and inconvenient service hours for SRH services. Knowing contraceptive methods and SRH services was also positively associated with adolescents’ contraceptive utilization. Conclusions. The proportion of adolescents who used contraception in Ethiopia was 40%. Adolescents’ use of contraceptives was influenced by a variety of factors: individual-, sociocultural-, healthcare-, and knowledge-related factors. Hence, integrated interventions targeted at tackling barriers to contraceptive uptake may be helpful to improve adolescents’ contraceptive utilization in Ethiopia.

Prevalence of needle-stick injury among nursing students: A systematic review and meta-analysis

Introduction

Needle-stick injuries (NSI) are a serious threat to the health of healthcare workers, nurses, and nursing students, as they can expose them to infectious diseases. Different prevalence rates have been reported for this type of injury in different studies worldwide. Therefore, this study aimedto estimate the pooled prevalence of NSI among nursing students.

Methods

This study was conducted by searching for articles in Web of Science, PubMed, Scopus, Embase, and Google Scholar without time limitation using the following keywords: needle-stick, needle stick, sharp injury, and nursing student. The data were analyzed using the meta-analysis method and random-effects model. The quality of the articles was evaluated with Newcastle-Ottawa Quality Assessment Scale (NOS). The heterogeneity of the studies was examined using the I 2 index, and the collected data were analyzed using the STATA Software Version 16.

Results

Initially, 1,134 articles were retrieved, of which 32 qualified articles were included in the analysis. Nursing students reported 35% of NSI (95% CI: 28-43%) and 63% (95% CI: 51-74%) did not report their needle-stick injuries. The highest prevalence was related to studies conducted in Asia (39.7%; 95% CI: 31.7-47.7%). There was no significant correlation among NSI prevalence and age of samples, and article year of publication.

Conclusion

A third of nursing students reported experiencing NSI. Consequently, occupational hazard prevention training and student support measures need to be considered.

Vitamin D-Related Genetic Variations and Nonalcoholic Fatty Liver Disease: A Systematic Review

Background: Studies have demonstrated the link between vitamin-D-related genetic variations and nonskeletal outcomes. We aimed to identify all available data on the association of vitamin-D-related genetic variations with nonalcoholic fatty liver disease (NAFLD). Methods: Potentially eligible studies were identified from Embase and Medline databases from inception to June 2022 using a search strategy that comprised terms for “Vitamin D” and “NAFLD”. Eligible studies must report the association between vitamin D-related genetic variations and presence, severity or response to treatment of NAFLD. Data were extracted from each eligible study. Results: A total of 3495 articles were identified. After a systematic review, twelve studies were included. A total of 26 genetic variations were identified. Presence of NAFLD was associated with variations of GC (rs222054, rs222020, rs10011000, rs7041), VDR (rs2228570, rs11168287, rs10783219, rs4752), CYP24A1 (rs3787557, rs6068816, rs2296241, rs2248359) and CYP27B1 (rs4646536). Severity of NAFLD was associated with variations of GC (rs4588), VDR (rs2228570, rs4334089), CYP2R1 (rs10741657), DHCR7 (rs1544410, rs3829251, rs12785878) and CYP24A1 (rs3787557, rs6068816, rs6097809, rs6127119, rs2248359, rs3787554, rs4809960, rs6022999). Response to calcitriol treatment was associated with variation of VDR (rs10735810). Conclusions: Multiple vitamin D-related genetic variations were associated with NAFLD, indicating the role of vitamin D in the pathogenesis of NAFLD.

Evaluation of efficacy and safety of intradermal delivery of vaccines through microneedle(s) in human beings: a protocol for a systematic review

BACKGROUND

Microneedles are defined as micron-sized projections with an insertion length ranging from 20 to 1500 μm and an external diameter up to 300 μm. Medications administered through microneedles diffuse through the deeper layers of the skin, into the systemic circulation, with minimal stimulation of pain-sensitive nerve endings. The rich presence of dendritic cells in the dermis makes microneedle-based vaccine delivery an attractive option. This systematic review will evaluate the efficacy and safety of intradermal delivery of vaccines using microneedles, in human beings.

METHODS

We will search the following databases for studies reporting the efficacy and/or safety of intradermal delivery of vaccines using microneedles: Epistemonikos and the Cochrane Library for systematic reviews and MEDLINE (through PubMed), EMBASE, Cochrane CENTRAL, LIVIVO, Web of Science, Scopus and CINAHL databases for primary studies. We will also search grey literature databases and hand search reference lists of relevant studies. We will include randomised and quasi-randomised trials in human beings (any age), using microneedles (any material, length or bore) to deliver vaccines intradermally, wherein outcomes reflecting efficacy, safety, pain responses, participant satisfaction or cost are reported. We will additionally include non-randomised observational studies for long-term safety outcomes that are not reported in trials. Eligibility for inclusion will be independently determined by two reviewers. The risk of bias of the included studies will be assessed using the Cochrane RoB2 Tool (for randomised trials) and Newcastle-Ottawa Scale (for other study designs). Data on efficacy and safety will be pooled through meta-analysis (where feasible). We will explore the heterogeneity amongst randomised trials, using the Higgins and Thompson I2 method. We will undertake sensitivity analysis to explore the impact of study quality and subgroup analysis based on the age of participants, length of microneedle and vaccine dosage. The GRADE approach will be used to estimate the confidence in the evidence.

RESULTS

This is a protocol for a systematic review; hence, there are no results at this stage.

DISCUSSION

The proposed systematic review will provide evidence on efficacy, safety, pain responses, participant acceptability and cost in human beings (adults and children) for vaccines administered through the intradermal route using microneedles. Since intradermal injections using microneedles are associated with less pain due to their short lengths and narrow bores, we anticipate that delivery of vaccine antigens using this method could be a safe, efficacious and less painful alternative compared with conventional injections using hypodermic needles. The evidence in this review will be useful for policymakers, vaccine manufacturers and healthcare providers to consider this approach for the vaccination of infants and children in routine immunisation programmes. Therefore, we plan to disseminate the review through a peer-reviewed journal publication and will also provide data that cannot be included in the published version to anyone upon reasonable request.

Safety and efficacy of the Amplatzer amulet and watchman2.5 for left atrial appendage occlusion: a Systematic review and meta-analysis

BACKGROUND

Left atrial appendage occlusion (LAAO) is an alternative to oral anticoagulation (OAC) to decrease the risk of stroke in patients with nonvalvular atrial fibrillation (NVAF); however, certain complications remain a concern. Amplatzer Amulet and Watchman are the two most popular used devices for preventing stroke in patients with NVAF. We assessed the safety and efficacy of LAAO using the Amplatzer Amulet and Watchman.

METHODS

A meta-analysis was conducted to compare the safety and efficacy outcomes associated with the use of the Amplatzer Amulet and Watchman 2.5. The Newcastle-Ottawa Scale has been utilized to assess the quality of study.

RESULTS

The meta-analysis includes seven studies involving 2,926 patients (1,418 patients with an amulet and 1,508 with a Watchman 2.5). Generally, adverse event rates for both systems were minimal. No significant differences between the two devices were found in safety (pericardial effusion, device embolization, and cardiac tamponade) or efficacy outcomes (death, TIA, stroke, major/minor bleeding, device leak, and thromboembolic events).

CONCLUSIONS

The data suggest LAAO is a safe procedure, regardless of which device was used. LAAO devices generally have low complication rates. Outcomes were comparable between the two groups with no significant differences in their safety or efficacy. This article is protected by copyright. All rights reserved.

Binge-Watching and Mental Health Problems: A Systematic Review and Meta-Analysis

BACKGROUND

Binge-watching, the viewing of online videos or streamed content, may be associated with different types of mental health problems. The present study aimed to investigate the associations between binge-watching and five mental health concerns including depression, loneliness, sleep problems, anxiety, and stress.

METHODS

Academic databases of PubMed, Scopus, Web of Science, ProQuest, PsycINFO, and Psych Articles were systematically searched through February of 2022. The Newcastle-Ottawa Scale was used to assess the methodological quality. A meta-analysis was performed on Fisher's z values as effect sizes, using a random effect model. Publication bias, small study effect, and moderators in this association were assessed.

RESULTS

Binge-watching was significantly associated with the five types of mental health concerns with the most robust correlations found with stress (0.32) and anxiety (0.25). Stronger associations between binge-watching and two types of mental health problems (depression and sleep problems) were found during the COVID-19 pandemic than before the pandemic. Moreover, stronger associations between binge-watching and two types of mental health problems (stress and sleep problems) were found in developing countries than in developed countries.

CONCLUSIONS

The associations between binge-watching and mental health concerns were significant and positive. Programs and interventions to reduce binge-watching should be considered and tested.

Risk of incident diabetes post-COVID-19: A systematic review and meta-analysis

It remains undetermined whether burden of diabetes newly detected during acute COVID-19 persist in post-acute COVID phase. This meta-analysis was conducted to summarize the available literature and provide a pooled estimate of the risk of developing incident diabetes following hospital discharge or at least 28 days after the COVID-19 diagnosis compared to matched controls or severity matched influenza/ non-COVID-19 acute upper respiratory tract infections (AURI). Pooled analysis of 5787,027 subjects from four observational studies showed 59 % higher risk of developing incident diabetes in post-acute COVID-19 phase versus healthy controls (HR:1.59; 95 % CI:1.40-1.81, p < 0.001, I2=94 %, random-effects model). The high degree of heterogeneity in pooled estimate can be attributed to difference in demographic characteristics, hospitalization rates or disease severity between study subjects. Pooling data from three studies, higher risk of incident diabetes was also observed following COVID-19 versus severity matched non-COVID-19 respiratory tract infections (moderate-severe/hospitalized cases, HR 1.52; 95 % CI: 1.36-1.70, p < 0.01, I2=0 %, fixed-effects model; mild cases, HR 1.22; 95 % CI: 1.14-1.31, p < 0.001; I2=0 %, fixed-effects model). Majority of studies had median follow-up period of around 4 months. In view of several limitations due to retrospective design of these studies, prospective studies with long term follow-up are warranted.

Capitellum and trochlea fractures. A systematic review of the literature

PURPOSE

To investigate the outcome of capitellum and trochlea fractures through a systematic review of the contemporary literature. The effect on the outcome, of the posterolateral column comminution and the surgical approach used for fixation, was also evaluated.

METHODS

PUBMED, SCOPUS and MENDELEY databases were searched for capitellum and trochlea fractures and a systematic review was conducted according to PRISMA guidelines. The minimum one year clinical outcome and the flexion extension arc of these fractures, as well as the risk of developing degenerative arthritis were evaluated. The studies included to the meta - analysis were assessed based on the Newcastle Ottawa score. A fixed effect model was performed to compare the outcome and range of motion among Dubberley type A and type B fractures as well as between the extended lateral approach and the posterior transolecranon approach which were performed for Dubberley type B fractures. Furthermore the relative risk of degenerative arthritis (DA) among type A and type B fractures was also estimated. Chi square test was used to test heterogenity among studies.

RESULTS

Ten nonrandomized case series were eligible to our inclusion criteria, including 76 patients in total. The fixed overall Mayo Elbow Performance Score (MEPS) and the Range of Motion (ROM) of the Dubberley type A fractures was 86 (95% C.I.: 85,1-86,9) and 124 0 (95% C.I.: 122 0-124 0) respectively. The fixed overall MEPS and ROM of the Dubberley type B fractures was 84 (95%C.I.: 79,9-88,1) and 122 0 (95% C.I.: 120 0-123 0) respectively. Significant heterogenity was found though between studies regarding MEPS of type B fractures. The fixed overall MEPS and ROM for fractures treated with an extended lateral approach was 89,4 (95% C.I.: 85,36-93,44) and 123 0 (120 0-126 0) respectively. The fixed overall MEPS and ROM for fractures treated with a posterior transolecranon approach was 68,75 (95% C.I.: 67,89-69,6) and 122 0 (114 0-130 0) respectively. The degenerative arthritis relative risk (RR) of type B compared to type A fractures was 3,91 (95% C.I.: 0,84-18,13).

CONCLUSION

There is no statistically significant difference among type A and type B fractures, in terms of outcome and ROM. The posterior transolecranon approach leads to a lower MEPS as opposed to the extended lateral approach. High quality studies comparing directly the outcome of type A and type B fractures are required, in order for safe conclusions to be extracted.

A systematic review on neutrophil extracellular traps and its prognostication role in COVID-19 patients

Neutrophil extracellular traps (NETs) are extracellular webs composed of neutrophil granular and nuclear elements. Because of the potentially dangerous amplification circuit between inflammation and tissue damage, NETs are becoming one of the investigated components in the current Coronavirus Disease 2019 (COVID-19) pandemic. The purpose of this systematic review is to summarize studies on the role of NETs in determining the prognosis of COVID-19 patients. The study used six databases: PubMed, Science Direct, EBSCOHost, Europe PMC, ProQuest, and Scopus. This literature search was implemented until October 31, 2021. The search terms were determined specifically for each databases, generally included the Neutrophil Extracellular Traps, COVID-19, and prognosis. The Newcastle Ottawa Scale (NOS) was then used to assess the risk of bias. Ten studies with a total of 810 participants were chosen based on the attainment of the prerequisite. Two were of high quality, seven were of moderate quality, and the rest were of low quality. The majority of studies compared COVID-19 to healthy control. Thrombosis was observed in three studies, while four studies recorded the need for mechanical ventilation. In COVID-19 patients, the early NETs concentration or the evolving NETs degradations can predict patient mortality. Based on their interactions with inflammatory and organ dysfunction markers, it is concluded that NETs play a significant role in navigating the severity of COVID-19 patients and thus impacting their prognosis.

The prevalence of feeding and eating disorders symptomology in medical students: an updated systematic review, meta-analysis, and meta-regression

PURPOSE

Medical students have a higher risk of developing psychological issues, such as feeding and eating disorders (FEDs). In the past few years, a major increase was observed in the number of studies on the topic. The goal of this review was to estimate the prevalence risk of FEDs and its associated risk factors in medical students.

METHODS

Nine electronic databases were used to conduct an electronic search from the inception of the databases until 15th September 2021. The DerSimonian-Laird technique was used to pool the estimates using random-effects meta-analysis. The prevalence of FEDs risk in medical students was the major outcome of interest. Data were analyzed globally, by country, by research measure and by culture. Sex, age, and body mass index were examined as potential confounders using meta-regression analysis.

RESULTS

A random-effects meta-analysis evaluating the prevalence of FEDs in medical students (K = 35, N = 21,383) generated a pooled prevalence rate of 17.35% (95% CI 14.15-21.10%), heterogeneity [Q = 1528 (34), P = 0.001], τ2 = 0.51 (95% CI 0.36-1.05), τ = 0.71 (95% CI 0.59-1.02), I2 = 97.8%; H = 6.70 (95% CI 6.19-7.26). Age and sex were not significant predictors. Body mass index, culture and used research tool were significant confounders.

CONCLUSION

The prevalence of FEDs symptoms in medical students was estimated to be 17.35%. Future prospective studies are urgently needed to construct prevention and treatment programs to provide better outcomes for students at risk of or suffering from FEDs.

Insulin resistance in depression: A large meta-analysis of metabolic parameters and variation

Increased insulin resistance is recognized in psychiatric disorders, such as schizophrenia and bipolar disorder, but its occurrence in depression is less clear. Our aims were to verify if insulin resistance is altered in depression, to test the metabolic subgroup hypothesis of depression and if there are changes with antidepressants. Inclusion criteria were studies including adult subjects with depression and either a control group or follow-up after treatment with antidepressants, and assessing fasting insulin or glucose levels or the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index. Seventy studies with 240,704 participants were included. Both insulin levels and the HOMA-IR index were increased in acute depression. Neither insulin nor the HOMA-IR index were altered during remission. Insulin was increased in atypical, but not typical depression. There was higher variation in insulin in individuals with depression than in controls. Insulin resistance did not change with antidepressant treatment. Insulin resistance is increased in depression during acute episodes. Heterogeneity was high in most of the analyses. Laboratory assessment of insulin resistance might have clinical utility in people with depression for diagnosis of the metabolic subtype and treatment selection, following precision psychiatry standards.

Prevalence and factors associated with psychological distress among adult patients with hypertension in a primary care clinic: A cross-sectional study

INTRODUCTION

Psychological distress worsens the control of hypertension. This study aims to fill the knowledge gap and evaluate the prevalence and factors associated with depression, anxiety, and stress among patients with hypertension in a primary care clinic.

METHODS

A cross-sectional study was conducted at Klinik Kesihatan Bandar Jerantut on hypertensive patients using a systematic random sampling method. Data were collected from 391 hypertensive patients using a self-administered questionnaire. Multiple logistic regression analysis was performed to identify the associated factors.

RESULTS

The response rate was 99.5% (389/391). The mean age of respondents was 60.1 years and 44.7% were male. The prevalence of psychological distress was the highest at 28.8%, followed by anxiety (21.3%), depressive (16.2%), and stress symptoms (13.9%). Uncontrolled blood pressure was significantly associated with depressive (OR: 6.4; 95% CI: 3.32-12.28), anxiety (OR: 4.9; 95% CI: 2.75-8.82), and stress symptoms (OR: 6.3; 95% CI: 3.06-12.98). Worry about the complications of hypertension was significantly associated with depressive (OR: 4.5; 95% CI: 2.08-9.94), anxiety (OR: 10.8; 95% CI: 4.15-28.17), and stress symptoms (OR: 5.3; 95% CI: 2.14-13.22). Other associated factors were physical inactivity, employment, lack of formal education, and low household income.

CONCLUSION

A quarter of hypertensive patients experienced psychological distress in terms of depressive, anxiety, or stress symptoms. We recommend screening for psychological distress among high-risk hypertensive patients, especially those cannot achieve adequate blood pressure control or those who are worried about the complications of hypertension.

Prognostic value of computed tomography derived skeletal muscle mass index in lung cancer: A meta-analysis

BACKGROUND

The prognostic role of the skeletal muscle mass index (SMI) derived from computed tomography (CT) imaging been well verified in several types of cancers. However, whether the SMI could serve as a reliable and valuable predictor of long-term survival in lung cancer patients remains unclear.

AIM

To identify the prognostic value of the CT-derived SMI in lung cancer patients.

METHODS

The PubMed, Web of Science, and Embase electronic databases were searched up to November 5, 2021 for relevant studies. The Reference Citation Analysis databases were used during the literature searching and selection. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated to assess the association of the SMI with the overall survival (OS) of lung cancer patients. All statistical analyses were performed with STATA 12.0 software.

RESULTS

A total of 12 studies involving 3002 patients were included. The pooled results demonstrated that a lower SMI was significantly related to poorer OS (HR = 1.23, 95%CI: 1.11-1.37, P < 0.001). In addition, the subgroup analyses stratified by treatment (nonsurgery vs surgery), tumor stage (advanced stage vs early stage), and tumor type (non-small cell lung cancer vs lung cancer) showed similar results.

CONCLUSION

The CT-derived SMI is a novel and valuable prognostic indicator in lung cancer and might contribute to the clinical management and treatment of lung cancer patients.

Early-Life Exposure to the Chinese Famine of 1959-1961 and Type 2 Diabetes in Adulthood: A Systematic Review and Meta-Analysis

BACKGROUND

The fast-growing literature suggests that the Chinese famine of 1959-1961 drives current and future type 2 diabetes (T2D) epidemics in China. This conclusion may be premature, as many Chinese famine studies have major methodological problems. We examine these problems, demonstrate how they bias the study results, and formulate recommendations to improve the quality of future studies.

METHODS

We searched English and Chinese databases for studies that examined the relationship between prenatal exposure to the Chinese famine and adult T2D from inception to 8 February 2022. We extracted information on T2D cases and study populations of individuals born during the famine (famine births), before the famine (prefamine births), and after the famine (postfamine births). We used random-effects models to compare the odds of T2D in famine births to several control groups, including postfamine births, combined pre- and postfamine births, and prefamine births. We used meta-regressions to examine the impacts of age differences between comparison groups on famine effect estimates and the role of other characteristics, including participant sex, age, and T2D assessments; famine intensity; residence; and publication language. Potential sources of heterogeneity and study quality were also evaluated.

RESULTS

Twenty-three studies met our inclusion criteria. The sample sizes ranged from less than 300 to more than 360,000 participants. All studies defined the famine exposure based on the participants' dates of birth, and 18 studies compared famine births and postfamine births to estimate famine effects on T2D. The famine and postfamine births had an age difference of three years or more in all studies. The estimates of the famine effect varied by the selection of controls. Using postfamine births as controls, the OR for T2D among famine births was 1.50 (95% CI 1.34-1.68); using combined pre- and postfamine births as controls, the OR was 1.12 (95% CI 1.02-1.24); using prefamine births as controls, the OR was 0.89 (95% CI 0.79-1.00). The meta-regressions further showed that the famine effect estimates increased by over 1.05 times with each one-year increase in ignored age differences between famine births and controls. Other newly identified methodological problems included the poorly assessed famine intensity, unsuitable study settings for famine research, and poor confounding adjustment.

INTERPRETATION

The current estimates of a positive relationship between prenatal exposure to the Chinese famine and adult T2D are mainly driven by uncontrolled age differences between famine births and postfamine births. Studies with more rigorous methods, including age-balanced controls and robust famine intensity measures, are needed to quantify to what extent the famine exposure is related to current T2D patterns in China.

Percutaneous transhepatic holmium laser lithotripsy for cholelithiasis and balloon dilation for common bile duct stone removal

Biliary lithiasis is common in clinical practice. We present the case of a 53-year-old man referred to our hospital with a history of biliary lithiasis. Abdominal magnetic resonance imaging revealed gallbladder stones and common bile duct stones. To avoid surgery, we opted to apply percutaneous transhepatic techniques to clear gallbladder and bile duct stones. This study reports our experience using these techniques, including percutaneous transhepatic holmium laser lithotripsy for cholelithiasis combined with balloon dilation to remove common bile duct stones and avoid open surgery.

Microscopic changes in the spinal extensor musculature in people with chronic spinal pain: a systematic review

BACKGROUND CONTEXT

Chronic spinal pain is one the most common musculoskeletal disorders. Previous studies have observed microscopic structural changes in the spinal extensor muscles in people with chronic spinal pain. This systematic review synthesizes and analyzes all the existing evidence of muscle microscopic changes in people with chronic spinal pain.

PURPOSE

To assess the microscopy of spinal extensor muscles including the fiber type composition, the area occupied by fiber types, fiber size/cross sectional area (CSA), and narrow diameter (ND) in people with and without chronic spinal pain. Further, to compare these outcome measures across different regions of the spine in people with chronic neck, thoracic and low back pain.

STUDY DESIGN

Systematic review with meta-analysis.

METHODS

MEDLINE (Ovid Interface), Embase, PubMed, CINAHL Plus, and Web of Science were searched from inception to October 2020. Key journals, conference proceedings, grey literature and hand searching of reference lists from eligible studies were also searched. Two independent reviewers were involved in the selection process. Only studies examining the muscle microscopy of the spinal extensor muscles (erector spinae [ES] and/or multifidus [MF]) between people with and without chronic spinal pain were selected. The risk of bias from the studies was assessed using modified Newcastle Ottawa Scale and the level of evidence was established using the GRADE approach. Data were synthesized based on homogeneity on the methodology and outcome measures of the studies for ES and MF muscles and only four studies were eligible for analysis.

RESULTS

All the five studies included were related to chronic low back pain (CLBP). Meta-analysis (inverse variance method for random effect to calculate mean difference and 95% CI) was performed for the ES fiber type composition by numbers for both type I and type II fibers (I²=43% and 0% respectively indicating homogeneity of studies) and showed no difference between the people with and without CLBP with an overall effect estimate Z= 1.49 (p=.14) and Z=1.06 (p=.29) respectively. Meta-analysis was performed for ES fiber CSA for both type I and type II fibers (I²=0 for both) and showed no difference between people with and without CLBP with an overall effect estimate Z=0.08 (p=.43) and Z=0.75 (p=.45) respectively. Analysis was not performed for ES area occupied by fiber types and ND due to heterogeneity of studies and lack of evidence respectively. Similarly, meta-analysis was not performed for MF fiber type composition by numbers due to heterogeneity of studies. MF analysis for area occupied by fiber type, fiber CSA and ND did not yield sufficient evidence.

CONCLUSIONS

For the ES muscle, there was no difference in fiber type composition and fiber CSA between people with and without CLBP and no conclusions could be drawn for ND for the ES. For the MF, no conclusions could be drawn for any of the muscle microscopy outcome measures. Overall, the quality of evidence is very low and there is very low evidence that there are no differences in microscopic muscle features between people with and without CLBP.

Consensus document of the Spanish Society of Digestives Diseases and the Spanish Society of Thrombosis and Haemostasis on massive nonvariceal gastrointestinal bleeding and direct-acting oral anticoagulants

INTRODUCTION

there is limited experience and understanding of massive nonvariceal gastrointestinal bleeding during therapy with direct-acting oral anticoagulants.

OBJECTIVES

to provide evidenced-based definitions and recommendations.

METHODS

a consensus document developed by the Spanish Society of Digestives Diseases and the Spanish Society of Thrombosis and Haemostasis using modified Delphi methodology. A panel was set up of 24 gastroenterologists with experience in gastrointestinal bleeding, and consensus building was assessed over three rounds. Final recommendations are based on a systematic review of the literature using the GRADE system.

RESULTS

panelist agreement was 91.53 % for all 30 items as a group, a percentage that was improved during rounds 2 and 3 for items where clinical experience is lower. Explicit disagreement was only 1.25 %. A definition of massive nonvariceal gastrointestinal bleeding in patients on direct-acting oral anticoagulants was established, and recommendations to optimize this condition's management were developed.

CONCLUSION

the approach to these critically ill patients must be multidisciplinary and protocolized, optimizing decisions for an early identification of the condition and patient stabilization according to the tenets of damage control resuscitation. Thus, consideration must be given to immediate anticoagulation reversal, preferentially with specific antidotes (idarucizumab for dabigatran and andexanet alfa for direct factor Xa inhibitors); hemostatic resuscitation, and bleeding point identification and management.

Efficacy and Safety of Lianhua Qingwen for Patients with COVID-19: A Systematic Review and Meta-Analysis

BACKGROUND

Corona virus disease 2019 (COVID-19) has spread around the world since its outbreak, and there is no ascertained effective drug up to now. Lianhua Qingwen (LHQW) has been widely used in China and overseas Chinese, which had some advantages in the treatment of COVID-19.

OBJECTIVE

To evaluate the efficacy and safety of LHQW for COVID-19 by conducting a systematic review with meta-analysis.

METHODS

A comprehensive literature search was conducted in 12 electronic databases from their establishment to October 30, 2021. Note Express 3.2.0 was used for screening of trials, and the data was independently extracted in duplicate by 2 researchers. The risk of bias of randomized controlled trials (RCTs) and retrospective studies were assessed by using the Cochrane collaboration tool and Newcastle Ottawa Scale, respectively, followed by data analysis using RevMan 5.3. The RCTs or retrospective studies to treat COVID-19 using LHQW were included. The intervention measures in the experimental group were LHQW alone or combined with chemical drugs (LCWC), and that in the control group were chemical drugs (CDs). Outcome measures included computed tomography (CT) recovery rate, disappearance rates of primary (fever, cough, fatigue), respiratory, gastrointestinal and other symptoms, exacerbation rate and adverse reaction. Subgroup analysis was conducted according to whether LHQW was combined with CDs and the different treatment methods in the control group.

RESULTS

Nine trials with 1,152 participants with COVID-19 were included. The CT recovery rates of LHQW and LCWC were 1.36 and 1.32 times of CDs, respectively (P<0.05). Compared with CDs, LCWC remarkably increased the disappearance rates of fever, cough, fatigue, expectoration, shortness of breath, and muscle soreness (P<0.05). LHQW also obviously decreased the exacerbation rate, which was 0.45 times of CDs alone (P<0.05). There was no obvious difference between LCWC and CDs in adverse reaction (P>0.05).

CONCLUSIONS

LHQW was more suitable for treating COVID-19 patients with obvious expectoration, shortness of breath and muscle soreness. LHQW had advantages in treating COVID-19 with no obvious exacerbation. (PROSPERO No. CRD42021235937).

Comparison between laparoscopic uncut Roux-en-Y and Billroth II with Braun anastomosis after distal gastrectomy: A meta-analysis

BACKGROUND

Conventional Billroth II (BII) anastomosis after laparoscopic distal gastrectomy (LDG) for gastric cancer (GC) is associated with bile reflux gastritis, and Roux-en-Y anastomosis is associated with Roux-Y stasis syndrome (RSS). The uncut Roux-en-Y (URY) gastrojejunostomy reduces these complications by blocking the entry of bile and pancreatic juice into the residual stomach and preserving the impulse originating from the duodenum, while BII with Braun (BB) anastomosis reduces the postoperative biliary reflux without RSS. Therefore, the purpose of this study was to compare the efficacy and safety of laparoscopic URY with BB anastomosis in patients with GC who underwent radical distal gastrectomy.

AIM

To evaluate the value of URY in patients with GC.

METHODS

PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, Chinese Biomedical Database, and VIP Database for Chinese Technical Periodicals (VIP) were used to search relevant studies published from January 1994 to August 18, 2021. The following databases were also used in our search: Clinicaltrials.gov, Data Archiving and Networked Services, the World Health Organization International Clinical Trials Registry Platform Search Portal (https://www.who.int/clinical-trials-registry-platform/the-ictrp-search-portal), the reference lists of articles and relevant conference proceedings in August 2021. In addition, we conducted a relevant search by Reference Citation Analysis (RCA) (https://www.referencecitationanalysis.com). We cited high-quality references using its results analysis functionality. The methodological quality of the eligible randomized clinical trials (RCTs) was evaluated using the Cochrane Risk of Bias Tool, and the non-RCTs were evaluated using the Newcastle-Ottawa scale. Statistical analyses were performed using Review Manager (Version 5.4).

RESULTS

Eight studies involving 704 patients were included in this meta-analysis. The incidence of reflux gastritis [odds ratio = 0.07, 95% confidence interval (CI): 0.03-0.19, P < 0.00001] was significantly lower in the URY group than in the BB group. The pH of the postoperative gastric fluid was lower in the URY group than in the BB group at 1 d [mean difference (MD) = -2.03, 95%CI: (-2.73)-(-1.32), P < 0.00001] and 3 d [MD = -2.03, 95%CI: (-2.57)-(-2.03), P < 0.00001] after the operation. However, no significant difference in all the intraoperative outcomes was found between the two groups.

CONCLUSION

This work suggests that URY is superior to BB in gastrointestinal reconstruction after LDG when considering postoperative outcomes.

The Incidence and Prevalence of Pulmonary Hypertension in the COPD Population: A Systematic Review and Meta-Analysis

Purpose

Chronic obstructive pulmonary disease (COPD)-related pulmonary hypertension (PH) is one of the most common comorbidities of COPD, and often leads to a worse prognosis. Although the estimated prevalence and risk factors of COPD-related PH have been widely reported, these results have not been well integrated. This study aimed to review the worldwide incidence and prevalence of COPD-related PH and explore possible factors affecting its prevalence.

Patients and Methods

We searched four electronic databases (Web of Science, Embase, Cochrane, and MEDLINE) to identify all observational studies on the prevalence of COPD-related PH from database creation until July 20, 2021. Eligibility screening, quality assessment, and data extraction of the retrieved studies were independently conducted by two reviewers. Meta-analyses were performed to determine the prevalence of PH in the COPD population. Random-effects meta-regression model analyses were conducted to investigate the sources of heterogeneity.

Results

Altogether, 38 articles were included in the meta-analyses. The pooled prevalence was 39.2% (95% CI: 34.0–44.4, I² = 97.6%) for COPD-related PH. Subgroup analyses showed that the prevalence of PH increased with COPD severity, where the majority (30.2%) had mild PH and the minority had severe PH (7.2%). Furthermore, we found a significant regional difference in the prevalence of COPD-related PH (P = 0.000), which was the highest in Africa (64.0%) and the lowest in Europe (30.4%). However, stratified studies on other factors involving mean age, sex, enrolment time, participant recruitment settings, and PH diagnostic methods showed no significant differences in prevalence (P >0.05).

Conclusion

The global incidence of PH in the COPD population is very high, and there are significant regional and international variations. Patients with COPD should be screened for PH and contributing risk factors to reduce the burden on individuals and society.

The Main Bacterial Communities Identified in the Sites Affected by Periimplantitis: A Systematic Review

(1) Background: Periimplantitis is an infectious condition that affects the periimplant tissue and is of bacterial etiology. However, to date, the exact bacterial flora involved in its occurrence is not known. The aim of this literature review was to summarize the articles published on this topic and to identify the main bacterial species isolated in periimplantitis. (2) Methods: The articles published in three databases were researched: Pubmed, Embase and Web of Science using Prisma guides and combinations of MeSH terms. We selected 25 items from the 980 found by applying the inclusion and exclusion criteria. (3) Results: We quantified the results of the 25 studies included in this review. In general, the most commonly identified bacterial species were Gram-negative anaerobic species, as Prevotella, Streptococcus, Fusobacterium and Treponema. (4) Conclusion: The most frequent bacteria in the periimplantitis sites identified in this review are Gram-negative anaerobic species, also involved in the pathogenesis of the periodontal disease.

Acute Kidney Injury in Adult Patients With Hepatocellular Carcinoma After TACE or Hepatectomy Treatment

Background

Acute kidney injury (AKI) is one of the most common complications in patients with cancer, yet the specific reasons, mechanisms, and the influence of AKI are not clear in hepatocellular carcinoma (HCC) after treatment. This meta-analysis aimed to find out the risk factors and the impact on mortality of AKI in adult patients with HCC after treatment using available published data.

Methods

We performed a systemic literature search using PubMed, Web of Science, and Embase, encompassing publications up until November 30, 2021 (inclusive), with 17 cohort studies involving 11,865 patients that fulfilled the prespecified criteria for inclusion in the meta-analysis. The number of AKI/non-AKI patients identified by risk factors, the number of AKI/non-AKI-related deaths, the incidence rates, the mortality rates, and the irreversible rates of AKI were derived and analyzed using STATA.

Results

Age, diabetes mellitus (DM), and the number of transarterial chemoembolization (TACE) sessions are risk factors for AKI in patients with HCC after TACE. On the other hand, male gender, age, DM, major resection of the liver, and operation-related transfusion are risk factors for AKI in patients with HCC after hepatectomy. The risk of mortality in those with renal failure due to AKI was up to 4.74 times higher than in those without AKI in a short-term observation period after TACE treatment.

Conclusions

Attention should be paid to the risk of AKI in HCC patients with DM. The occurrence of AKI during TACE treatment is especially dangerous and should be considered a strong red flag, obviously with regard to the extremely high risk of death in a short period. Furthermore, studies are needed to detect more associations of AKI in patients with HCC.

Community-based care models for arterial hypertension management in non-pregnant adults in sub-Saharan Africa: a literature scoping review and framework for designing chronic services

BACKGROUND

Arterial hypertension (aHT) is the leading cardiovascular disease (CVD) risk factor in sub-Saharan Africa; it remains, however, underdiagnosed, and undertreated. Community-based care services could potentially expand access to aHT diagnosis and treatment in underserved communities. In this scoping review, we catalogued, described, and appraised community-based care models for aHT in sub-Saharan Africa, considering their acceptability, engagement in care and clinical outcomes. Additionally, we developed a framework to design and describe service delivery models for long-term aHT care.

METHODS

We searched relevant references in Embase Elsevier, MEDLINE Ovid, CINAHL EBSCOhost and Scopus. Included studies described models where substantial care occurred outside a formal health facility and reported on acceptability, blood pressure (BP) control, engagement in care, or end-organ damage. We summarized the interventions' characteristics, effectiveness, and evaluated the quality of included studies. Considering the common integrating elements of aHT care services, we conceptualized a general framework to guide the design of service models for aHT.

RESULTS

We identified 18,695 records, screened 4,954 and included twelve studies. Four types of aHT care models were identified: services provided at community pharmacies, out-of-facility, household services, and aHT treatment groups. Two studies reported on acceptability, eleven on BP control, ten on engagement in care and one on end-organ damage. Most studies reported significant reductions in BP values and improved access to comprehensive CVDs services through task-sharing. Major reported shortcomings included high attrition rates and their nature as parallel, non-integrated models of care. The overall quality of the studies was low, with high risk of bias, and most of the studies did not include comparisons with routine facility-based care.

CONCLUSIONS

The overall quality of available evidence on community-based aHT care is low. Published models of care are very heterogeneous and available evidence is insufficient to recommend or refute further scale up in sub-Sahara Africa. We propose that future projects and studies implementing and assessing community-based models for aHT care are designed and described according to six building blocks: providers, target groups, components, location, time of service delivery, and their use of information systems.

Occultism and playing with the dead: When rituals go wrong

There have been at least two deaths in Albania linked to ritualistic/satanic practices, which have provoked considerable public concern. Until the 1990s, Albania was strictly atheist. However, since then some religious sects have been establishing themselves. In fact, satanic killings and ritualistic deaths are rare in Albania. We describe two such cases that occurred in 2020 along with consideration of the psychological profiles of perpetrators and victims.The first case involved two deaths: a mother and daughter whose bodies were found near each other, with another daughter in attendance who was diagnosed as clearly psychotic, and legally did not face any charge thereafter. This daughter was witnessing the decomposition of her sister's mummified corpse. She said she was waiting for the "Messiah" to resurrect her. Apparently, while performing ritualistic ceremonies, the daughter and her mother refused food until the mother died from starvation. It was at that point that police broke into the house and discovered the situation.The second case involved a young woman who was found dead, apparently following a trivial infection. Her body (abdomen and dorsum) had written symbols on it, suggesting Satanism and the occult.A detailed analysis of the death scenes and crime scenes provide valuable data for further proceedings, but psychological evaluation of the perpetrators may prove more difficult, and more so where the victims have died.

Ki-67 assessment of pancreatic neuroendocrine neoplasms: Systematic review and meta-analysis of manual vs. digital pathology scoring

Ki-67 assessment is a key step in the diagnosis of neuroendocrine neoplasms (NENs) from all anatomic locations. Several challenges exist related to quantifying the Ki-67 proliferation index due to lack of method standardization and inter-reader variability. The application of digital pathology coupled with machine learning has been shown to be highly accurate and reproducible for the evaluation of Ki-67 in NENs. We systematically reviewed all published studies on the subject of Ki-67 assessment in pancreatic NENs (PanNENs) employing digital image analysis (DIA). The most common advantages of DIA were improvement in the standardization and reliability of Ki-67 evaluation, as well as its speed and practicality, compared to the current gold standard approach of manual counts from captured images, which is cumbersome and time consuming. The main limitations were attributed to higher costs, lack of widespread availability (as of yet), operator qualification and training issues (if it is not done by pathologists), and most importantly, the drawback of image algorithms counting contaminating non-neoplastic cells and other signals like hemosiderin. However, solutions are rapidly developing for all of these challenging issues. A comparative meta-analysis for DIA versus manual counting shows very high concordance (global coefficient of concordance: 0.94, 95% CI: 0.83-0.98) between these two modalities. These findings support the widespread adoption of validated DIA methods for Ki-67 assessment in PanNENs, provided that measures are in place to ensure counting of only tumor cells either by software modifications or education of non-pathologist operators, as well as selection of standard regions of interest for analysis. NENs, being cellular and monotonous neoplasms, are naturally more amenable to Ki-67 assessment. However, lessons of this review may be applicable to other neoplasms where proliferation activity has become an integral part of theranostic evaluation including breast, brain, and hematolymphoid neoplasms.

Frailty scoring in vascular and endovascular surgery: A systematic review

One in 10 independently living adults aged 65 years old and older is considered frail, and frailty is associated with poor postoperative outcomes. This systematic review aimed to examine the association between frailty assessments and postoperative outcomes in patients with vascular disease. Electronic databases - MEDLINE, Embase, and the Cochrane Library - were searched from inception until January 2022, resulting in 648 articles reviewed for potential inclusion and 16 studies selected. Demographic data, surgery type, frailty measure, and postoperative outcomes predicted by frailty were extracted from the selected studies. The risk of bias was assessed using the Newcastle-Ottawa Scale. The selected studies (mean age: 56.1-76.3 years) had low-to-moderate risk of bias and included 16 vascular (elective and nonelective) surgeries and eight frailty measures. Significant associations (p < 0.05) were established between mortality (30-day, 90-day, 1-year, 5-year), 30-day morbidity, nonhome discharge, adverse events, failure to rescue, patient requiring care after discharge, and amputation following critical limb ischaemia. The strongest evidence was found between 30-day mortality and frailty. Composite 30-day morbidity and mortality, functional status at discharge, length of stay, spinal cord deficit, and access site complications were found to be nonsignificantly associated with frailty. With frailty being significantly associated with several adverse postoperative outcomes, preoperative frailty assessments can potentially be clinically useful in helping practitioners predict and guide the pre-, peri-, and postoperative management of frail with vascular disease.

Arrhythmogenic Right Ventricular Cardiomyopathy Prevalence and Arrhythmic Outcomes in At-Risk Family Members: A Systematic Review and Meta-Analysis

Background:

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a complex cardiomyopathy with autosomal dominant inheritance and age-related incomplete penetrance, characterized by a high risk of sudden cardiac death. Recent professional consensus guidelines recommend clinical cardiac lifelong serial screening for at-risk family members refined only by age, but family genotype might influence necessary screening. Although numerous studies report prevalence of disease and arrhythmia in family members and explore predictors of penetrance and arrhythmic risk, a systematic review consolidating this evidence is lacking.

Methods:

We searched Medline (PubMed), Embase, The Cochrane Library, and Web of Science for studies that reported prevalence of (1) diagnosis of ARVC per 2010 Task Force Criteria and/or (2) sustained ventricular arrhythmias (VA) in at least 10 family members of definite patients with ARVC.

Results:

We identified 41 studies, including 36 that reported diagnosis by Task Force Criteria and 22 VA. Meta-analysis of 1359 family members, from 13 unique cohorts showed an average prevalence estimate of 25% for diagnosis as per Task Force Criteria (95% CI, 0.15–0.35, I 2 = 96.44%). Overall prevalence of VA among gene-positive family members was 18% (95% CI, 0.13–0.23, I 2 =33.25%) in 7 independent studies (n=597). Family genotype was a significant risk factor for diagnosis of both ARVC (odds ratio, 6.91 [95% CI, 1.27–37.70]; P =0.0005) and VA (odds ratio, 13.62 [95% CI, 0.91–204.13]; P =0.06). Male gender was not associated with disease prevalence (odds ratio, 1.18 [95% CI, 0.72–1.95]; P =0.42) or VA (odds ratio, 0.81 [95% CI, 0.51–1.29]; P =0.91).

Conclusions:

The prevalence of ARVC and VA in at-risk family members differs significantly based on family genotype. Although recent recommendations provide a guideline based only on age, we propose screening every 1 to 2 years for gene-positive family members and every 3 to 5 years for first-degree relatives of gene-elusive cases, as long as they are asymptomatic and not athletes.

The Durable Safety and Effectiveness of Lixisenatide in Japanese People with Type 2 Diabetes: The Post-Marketing Surveillance PRANDIAL Study

Introduction

Real-world evidence on lixisenatide in Japanese people with type 2 diabetes (T2D) is lacking. Therefore, the 3-year post-marketing PRANDIAL study was conducted to evaluate the safety (primary objective) and effectiveness (secondary objective) of lixisenatide in Japanese people with T2D during routine clinical practice.

Methods

This prospective, observational, multicenter, open-label study was conducted in Japanese individuals with T2D who initiated lixisenatide treatment between March 2014 and June 2017. Using electronic case report forms, investigators collected baseline demographic and clinical information and data on medications, safety and effectiveness up to 3 years after initiation of lixisenatide.

Results

Overall, 3046 participants were analyzed; their mean ± standard deviation (SD) age was 58.9 ± 13.1 years, and 53.7% were male. Mean ± SD duration of T2D was 12.8 ± 8.6 years, and baseline glycated hemoglobin (HbA1c) was 8.7% ± 1.7%. Most participants (93.9%) were receiving concomitant antidiabetic medications when they initiated lixisenatide. Median (range) lixisenatide treatment duration was 382 (1–1096) days. Adverse drug reactions (ADRs) were reported in 604 participants (19.8%) and serious ADRs in 22 (0.7%). The most common ADR was nausea (9.0%). Of ADRs of special interest, hypoglycemia occurred in 2.9% of participants, injection site reactions in 0.9%, and hypoglycemic unconsciousness in 0.03%. Baseline characteristics associated with an increased risk of ADRs (p < 0.05) were history of treatment for cardiovascular disease, hepatic dysfunction, and other complications. Effectiveness was analyzed in 2675 participants; HbA1c, fasting plasma glucose, postprandial glucose, and body weight all decreased significantly at last observation (all p < 0.0001 vs. baseline).

Conclusions

Lixisenatide was well tolerated, with no unexpected ADRs or new safety signals identified, and showed effective glycemic control and weight reduction up to 3 years, supporting the use of lixisenatide as a safe and effective treatment option for T2D in routine clinical practice in Japan.

Supplementary Information

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are antidiabetic drugs that lower blood glucose levels by stimulating the release of insulin and suppressing glucagon, the key hormones involved in controlling blood glucose levels in the body. The selective GLP-1RA lixisenatide was approved for the management of adults with type 2 diabetes (T2D) in Japan based on data from randomized clinical trials. However, these studies may not be representative of the safety and effectiveness of the drug when used in routine clinical practice. Therefore, we conducted the 3-year post-marketing PRANDIAL study to assess the safety and effectiveness of lixisenatide in 3046 Japanese individuals with T2D who started the drug between March 2014 and June 2017. Adverse drug reactions (adverse events for which lixisenatide causality could not be excluded) occurred in 19.8% of participants, with the most common adverse drug reaction being nausea. Hypoglycemia (abnormally low blood glucose levels) was reported in 2.9%. Individuals with a history of treatment for cardiovascular disease, hepatic dysfunction, and other complications had an increased risk of adverse drug reactions. Lixisenatide provided significant improvements in blood glucose control, with significant decreases in glycated hemoglobin (a marker of blood glucose control), fasting plasma glucose, and postprandial glucose levels from baseline, as well as significant reductions in body weight. In this real-world post-marketing surveillance study, lixisenatide was well tolerated, raising no new safety concerns, and provided durable effective blood glucose control and weight reduction. These results support the use of lixisenatide in Japanese individuals with T2D in routine clinical practice.

PD-L1 in oral squamous cell carcinoma: A key biomarker from the laboratory to the bedside

OBJECTIVES AND BACKGROUND

Oral squamous cell carcinoma (OSCC) is a highly malignant disease with an increasing incidence. The need to improve therapeutic strategies for patients affected by OSCC is an urgent challenge. Currently, the advent of immunotherapy represents an important step toward this aim. Programmed cell death-ligand 1 (PD-L1), a membrane protein that can be expressed on tumor and inflammatory cells is a key biomarker whose expression is determined by means of immunohistochemistry and is necessary for selecting patients for immunotherapy.

METHODS

In this study, we review the methods of PD-L1 assessment and outcomes achieved with immunotherapy in the treatment of OSCC patients.

RESULTS

Based on a meta-analysis we demonstrate a lack of prognostic significance of PD-L1 in OSCC.

CONCLUSIONS

We also highlight unresolved issues including difficulties in standardizing PD-L1 evaluation and discuss future opportunities such as leveraging digital pathology.

Feasibility of Implementing Cancer-Specific Community-Based Exercise Programming: A Multi-Centre Randomized Trial

BACKGROUND

There is growing recognition of the importance of reporting preliminary work on the feasibility of a trial. The present study aimed to assess the feasibility of (1) a proposed fitness testing battery, and (2) processes related to the implementation of cancer-specific exercise programming in a community setting.

METHODS/DESIGN

A randomized controlled implementation feasibility trial was performed in advance of a large-scale implementation study. Eligible participants within 18 months of a cancer diagnosis were randomized to immediate or delayed community-based exercise at YMCA locations in Calgary and Edmonton, Canada for an 8-week period. The primary outcome for the trial was the feasibility of the physical fitness testing battery, defined as a 70% or greater completion rate across the 24-week study period. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework was used to evaluate processes related to implementation of the exercise program across the two sites.

RESULTS

Eighty participants were recruited, 73 (91%) completed the 8-week trial, and 68 (85%) completed the 16- and 24-week follow-ups. Sixty participants (75%) completed the full physical fitness test battery at each time point, and 59 (74%) completed the patient-reported outcome measures. Statistically significant between-group differences were found in favor of the exercise group for functional aerobic capacity, upper and lower extremity strength, and symptoms. Differences were found between the sites, however, in completion rates and processes related to program implementation.

DISCUSSION

Findings suggest the need for minor adaptations to the physical fitness battery and outcome measures to better fit the community context. While findings support feasibility, context-specific challenges related to implementation processes were identified.

Relationship Between Cardiovascular Disease Risk Factors and Quality of Life in Patients with Metabolic-Associated Fatty Liver Disease

Background: Metabolic-associated fatty liver disease (MAFLD) is a common cause of liver-related mortality and morbidity worldwide. However, there is a paucity of literature on the relationship between cardiovascular disease (CVD) risk factors and quality of life (QoL) in patients with MAFLD. Objectives: This study aimed to examine the association between QoL and CVD risk factors in an Iranian MAFLD population. Methods: This study was conducted on MAFLD patients, referred to the gastroenterology clinic of a general hospital from September 2017 until September 2018. The QoL and Framingham Risk Score (FRS) were determined using the WHOQOL-BREF questionnaire and an online web calculator, respectively. A hierarchical multiple linear regression model was developed to evaluate the association between QoL and FRS after adjusting for the sociodemographic characteristics. Results: This study was performed on 200 participants. All domains of QoL were associated with older age, hypertension, smoking, diabetes mellitus, higher systolic blood pressure, and lower high-density lipoprotein levels in the univariate regression analysis (P < 0.05 for all). Meanwhile, FRS was adversely correlated with the total QoL score (correlation coefficient: -0.49; 95% CI: -0.61, -0.35; P < 0.001). After adjusting for the sociodemographic variables, the results of the hierarchical multiple linear regression model showed that age, smoking, diabetes mellitus, hypertension, and FRS were correlated with the overall QoL score (P < 0.05 for all). Hypertension was the main predictor of the total QoL score (B = -5.51, 95% CI: -7.18, -3.68; P < 0.05). A higher FRS was inversely associated with the physical domain of QoL (B = -0.05, 95% CI: -0.09, -0.01; P < 0.05), the environment domain of QoL (B = -0.04, 95% CI: -0.09, -0.01; P < 0.05), and the total score of QoL (B = -0.04, 95% CI: -0.08, -0.02; P < 0.05). Conclusions: According to the results of this study, a higher risk of developing CVD may reduce QoL in patients with MAFLD. Hypertension, diabetes mellitus, and smoking were the key predictive determinants of QoL in this population. Further studies are suggested to determine if modification of the mentioned risk factors can improve QoL in MAFLD patients.
