Food waste warriors: Indonesian communities engage through workshops and social media education

Food waste is food appropriate for human consumption but discarded in the retail or consumption process. In 2022, food waste accounts for 40.9% of Indonesia’s waste composition. Therefore, food waste community education is critical for reducing food waste. Community education can reach the young generation through workshops and social media. This research aims to evaluate various workshops and social media content in educating teenagers about food waste through community. The PRISMA guidelines become the foundation as a contribution to Sustainable Development Goals. We utilized databases such as EBSCO Host, SAGE, Taylor & Francis, and Wiley Online Library to search for relevant studies. This study’s approach is normative research including secondary data, comprehensive literature review such as workshops, social media, and food waste education journals in Indonesia. This systematic review examines food waste education content of workshops and social media in Indonesia also further content recommendations. This systematic review collected 52 papers, including journals and proceedings. The community education content in Indonesia focuses on recycling with 28.57%. Seminars/online campaigns dominate the education form with sustainable development goals (SDGs) achieved: climate action and zero hunger. This systematic review showed that it is essential to add actions toward food waste in the form of actual activities.

Hepatitis B virus infection during pregnancy and the risk of postpartum hemorrhage: a protocol for systematic review and meta-analysis

Background: Hepatitis B virus (HBV) infection is a significant public health issue worldwide, with a hepatitis B surface antigen (HBsAg) seroprevalence of 3.5%. Maternal HBV infection during pregnancy, a common comorbidity, is associated with an increase in the risk of adverse obstetric and perinatal outcomes. However, the relationship between maternal HBV infection and postpartum hemorrhage (PPH), a leading contributor to maternal morbidity and mortality, is currently uncertain. The aim of this study is to comprehensively clarify the potential impact of maternal HBV on PPH risk. Methods and Analysis: The authors initially searched five English databases and three Chinese databases from their inception to 26th June 2023. Two reviewers will independently conduct study selection, data extraction, and quality assessment. Cohort and case–control studies investigating the effect of maternal HBV infection on PPH will be included, with study quality assessed using the Newcastle–Ottawa Scale (NOS). Meta-analyses will be performed using a fixed-effects model for I 2≤50% or a random-effects model otherwise. Several categories of subgroup analyses (e.g. sample size more than 1000 vs. less than 1000) and sensitivity analyses (e.g. omit NOS scores less than 7) will be conducted, and publication bias will be assessed through funnel plots, Begg’s and Egger’s tests using STATA 18.0. Ethics and Dissemination: This systematic review and meta-analysis do not require ethics approval and the results will be published in peer-reviewed journals. The findings of this systematic review will provide evidence on the impact of maternal HBV infection on PPH, which will contribute to better prevention and management of PPH in clinical practice and a better understanding of the disease burden of HBV infection.

Prevalence of postnatal anxiety disorders in mothers of preterm infants: a systematic review protocol.

The objective of this systematic review is to evaluate and synthesize the available evidence on the prevalence of postnatal anxiety disorders in mothers of preterm infants within 12 months of delivery. Mothers of preterm infants report more postpartum psychological problems than other mothers. Anxiety disorders are among the most frequently reported manifestations, and affect the quality of maternal care and the baby's development. However, data on the prevalence of postnatal anxiety disorders in mothers of preterm infants are inconsistent and imprecise. It is, therefore, necessary to estimate the prevalence of anxiety disorders among mothers of premature infants in order to develop appropriate interventions for screening, support, and treatment. This review will consider studies conducted in any setting and any geographical location that report on the prevalence of any anxiety disorders in mothers of preterm infants within 12 months of delivery. Any analytical or descriptive observational studies and experimental or quasi-experimental studies will be included. MEDLINE (Ovid), PsycINFO (Ovid), Embase (Elsevier), CINAHL (EBSCOhost), Google Scholar, MedNar, and the World Health Organization website will be searched for studies written in English or French. Screening, critical appraisal, and data extraction will be performed by 2 independent reviewers using the relevant JBI systematic review tools. The findings will be presented in narrative format, including tables and figures to aid in data presentation. PROSPERO CRD42023428202.

Trimester-specific diagnostic accuracy of ultrasound for detection of placenta accreta spectrum: systematic review and meta-analysis.

To assess the diagnostic accuracy of ultrasound for detecting placenta accreta spectrum (PAS) during the first trimester of pregnancy and compare it with the accuracy of second- and third-trimester ultrasound examination in pregnancies at risk for PAS. PubMed, EMBASE and Web of Science databases were searched to identify relevant studies published from inception until 10 March 2023. Inclusion criteria were cohort, case-control or cross-sectional studies that evaluated the accuracy of ultrasound examination performed at < 14 weeks of gestation (first trimester) or ≥ 14 weeks of gestation (second/third trimester) for the diagnosis of PAS in pregnancies with clinical risk factors. The primary outcome was the diagnostic accuracy of sonography in detecting PAS in the first trimester, compared with the accuracy of ultrasound examination in the second and third trimesters. The secondary outcome was the diagnostic accuracy of each sonographic marker individually across the trimesters of pregnancy. The reference standard was PAS confirmed at pathological or surgical examination. The potential of ultrasound and different ultrasound signs to detect PAS was assessed by computing summary estimates of sensitivity, specificity, diagnostic odds ratio and positive and negative likelihood ratios. A total of 37 studies, including 5764 pregnancies at risk of PAS, with 1348 cases of confirmed PAS, were included in our analysis. The meta-analysis demonstrated that ultrasound had a sensitivity of 86% (95% CI, 78-92%) and specificity of 63% (95% CI, 55-70%) during the first trimester, and a sensitivity of 88% (95% CI, 84-91%) and specificity of 92% (95% CI, 85-96%) during the second/third trimester. Regarding sonographic markers examined in the first trimester, lower uterine hypervascularity exhibited the highest sensitivity (97% (95% CI, 19-100%)), and uterovesical interface irregularity demonstrated the highest specificity (99% (95% CI, 96-100%)). In the second/third trimester, loss of clear zone had the highest sensitivity (80% (95% CI, 72-86%)), and uterovesical interface irregularity exhibited the highest specificity (99% (95% CI, 97-100%)). First-trimester ultrasound examination has similar accuracy to second- and third-trimester ultrasound examinations for the diagnosis of PAS. Routine first-trimester ultrasound screening for patients at high risk of PAS may improve detection rates and allow earlier referral to tertiary care centers for pregnancy management. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Herbs Used for the Management of Hypertension: A Systematic Review

Background: Hypertension is characterized by persistent high blood pressure and has emerged as a critical risk factor for severe cardiovascular diseases. Although several drugs have been designated to reduce blood pressure, these drugs can potentially cause side effects for patients. Therefore, medicinal plants are used to complement conventional drugs to treat various ailments. Methods: This study reviews the anti-hypertensive potential of herbs and plants and their mechanism of action in reducing blood pressure at their evaluated effective doses. Databases such as PubMed, Scopus, Science Direct, and Google Scholar were used to search articles from January 2016 to Sept 2022. The key search terms included “hypertension”, “lowers blood pressure”, “anti-hypertensive”, and “plants”. These generated 807 documents and using the PRISMA guidelines, thirty plants were identified for this review. Research studies with similar plant parts extracted from similar solvents, more than one dose, and animal models with a positive control were considered in this review. Studies that did not show significant blood pressure reduction were excluded. Results: Based on this criterion, the mechanism of actions of these plants was thematically grouped into three categories, namely 1) antioxidant, 2) angiotensin-converting enzyme (ACE) inhibition, and 3) calcium influx in vascular smooth muscle. The effective doses, plant parts used, and traditional medicine usage are presented in this review. Conclusion: Further research is highly recommended to identify the active compounds and to potentially develop them into anti-hypertensive drugs as well as to establish the safe doses and standardization of these plant extracts. This review is partially funded by grants from the Ministry of Higher Education.

Prevalence and incidence of oral cancer and pre-cancerous lesions in indigenous populations: a systematic review protocol.

This review will determine the prevalence and incidence of oral cancer and pre-cancerous lesions in indigenous populations. There are approximately 476 million indigenous individuals worldwide. Oral cancer affected over 350,000 people globally in 2018, with approximately 80% of cases occurring in the indigenous population. Moreover, the incidence of pre-cancerous lesions is high in this population, accounting for 48.3%. Limited evidence exists regarding the burden of oral cancer among indigenous populations despite research on oral health disparities in this group. Studies on the burden of oral cancer and pre-cancerous lesions in indigenous groups, considering rates, ratios (prevalence or mortality), or survival proportions, will be considered for inclusion. There will be no limitations on study design, language, age, gender, or geography. We will exclude studies that only identify, diagnose, or screen oral cancer and pre-cancerous lesions without mentioning prevalence and incidence. This review will follow the JBI methodology for systematic reviews of prevalence and incidence. Databases to be searched will include MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCOhost), Cochrane Central Register of Controlled Trials, Scopus, and Dentistry and Oral Sciences Source (EBSCOhost). ProQuest Dissertations and Theses, OAIster, International Association for Dental Research conference abstracts, Google Scholar, government reports, and cancer registry reports will also be screened for unpublished studies. Two reviewers will independently screen articles, and data will be extracted using a customized form. Narrative data synthesis will be conducted and, where appropriate, meta-analysis will be performed. Methodological quality will be assessed using JBI's critical appraisal tool for prevalence studies.

Cost-effectiveness of newborn screening for sickle cell disease: a systematic review protocol.

The purpose of this systematic review is to assess the cost-effectiveness of targeted/selective newborn screening compared with universal screening for sickle cell disease across various countries and settings. The incidence of sickle cell disease is a widespread and potentially fatal hematologic disorder that affects thousands of newborns worldwide. The cost of newborn screening creates a burden on households and the economy. Studies will be eligible for inclusion in the review if they focus on the cost-effectiveness of newborn screening for sickle cell disease, comparing targeted/selective screening with universal screening. A preliminary search of MEDLINE (PubMed) was undertaken using MeSH terms, such as sickle cell disease, newborn , and economic evaluations . Two reviewers will screen the titles, abstracts, and full text independently against the inclusion criteria. Disagreements will be resolved by discussion or with a third reviewer. To assess methodological quality, the JBI checklist for economic evaluation will be used. Data will be extracted by 2 reviewers using a modified JBI data extraction form. The JBI dominance ranking matrix for economic evaluations will be used to summarize and compare the results. Cost-effectiveness will be measured on the basis of cost per test/case detected, quality-adjusted life years gained, or disability-adjusted life years averted. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) assessment will be conducted to evaluate the certainty of economic evidence, such as use of resources and expenditures, and to incorporate the results into the decision-making process.

The article addresses the impact of the COVID-19 pandemic on Small and Medium Enterprises (SMEs), focusing on the Information Technology (IT) investments made by these companies between 2020 and 2023. The health crisis generated significant economic effects, particularly in emerging economies, exacerbating pre-existing economic fragility and inequality. The study seeks to identify, through a systematic review of the literature, the investments, contributions, and uses of IT by SMEs located in Latin American, Asian, and European countries during the aforementioned period. It is concluded that, during COVID-19, IT investments in SMEs were not only a response to crises, but also a strategic source of resilience and financial stability. IT investment was highlighted as essential for innovation, digital transformation, and business continuity. Although low employee digital skills persist, the trend towards IT investment is positive, allowing SMEs to take advantage of technological and governmental opportunities to face the challenging economic context.

Effectiveness of transoral robotic surgery for recurrent head and neck cancers: a systematic review protocol.

The objective of this systematic review is to evaluate the best available evidence regarding effectiveness of transoral robotic surgery in patients with recurrent head and neck cancers. Transoral robotic surgery is now an established modality of treatment for primary head and neck cancer, showing good swallowing outcomes and quality of life for patients post-treatment. In patients with recurrent disease, conventional open surgery is often used, which prolongs recovery time and necessitates tissue disruption to gain access to the tumor site. Transoral robotic surgery is an emerging technique in this field as a minimally invasive approach to resection. The review will include experimental or observational studies that investigated the use of transoral robotic surgery in adults (aged 18 years or older) with recurrent head and neck cancers for oncological, functional, and survival outcomes. Three databases will be searched for evidence: PubMed, Embase, and Scopus. Search terms for each database will include transoral robotic surgery, recurrent, salvage , and head and neck cancers . Reference lists of included articles will be searched for further evidence. Critical appraisal will be conducted by 2 independent reviewers using the JBI critical appraisal tools for quantitative studies. Data will be extracted by the same reviewers. Where appropriate, meta-analysis will be conducted for all outcomes. PROSPERO CRD42023404613.

Background: Previous studies have reached mixed conclusions regarding the timing of endoscopic approaches for managing individuals with acute upper gastrointestinal bleeding (AUGIB). Therefore, the authors performed a protocol for systematic review and meta-analysis to assess the efficacy of various timing endoscopic approaches in managing individuals with AUGIB. Methods: The authors will search multiple databases, including PubMed, Embase, Web of Science, China National Knowledge Infrastructure, VIP Database, Wanfang Database, WHO International Clinical Trials Registry Platform, and Chinese Clinical Trial Register. The search will cover the entire duration, starting from the establishment of these databases until July 2023. The selection criteria will focus on randomized controlled trials that assess the efficacy of endoscopy with varying timing in managing patients with AUGIB. The primary outcomes will include primary hemostasis and inpatient death. The secondary outcomes will include recurrent bleeding, need for surgical intervention, admission to the ICU, blood transfusion needs, and duration of hospitalization. Two reviewers will select the studies, extract data, and assess the risk of bias. A Bayesian approach will be used to conduct a network meta-analysis. Results: The results of this systematic review and meta-analysis will be published in peer-reviewed journals. Conclusion: This network meta-analysis provides comprehensive evidence of different timing endoscopic approaches for managing individuals with AUGIB.

3Mixtatin versus MTA in pulp therapy of primary teeth: a systematic review and meta-analysis of current randomized controlled trials.

3Mixtatin (a combination of Metronidazole, Minocycline, and Ciprofloxacin along with statins) is a novel biomaterial in pulp therapy, while Mineral Trioxide Aggregate (MTA) is considered the gold standard in endodontics. This study aimed to compare the clinical and radiographic success rates of MTA and 3Mixtatin in pulp therapy of primary teeth. MEDLINE (PubMed), CENTRAL, Web of Science, Scopus, ProQuest databases, and Google Scholar were searched to identify randomized controlled trials (RCTs) on pulp therapy with 3Mixtatin and MTA in primary teeth, published up to February 2023. It should be noted that the protocol was previously registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42021243626). RCTs were assessed independently by two researchers in terms of eligibility and quality. Data extracted and tabulated. The Cochrane Risk of Bias (RoB-2) tool was used to assess the risk of bias. The effect sizes were evaluated utilizing risk ratios (RRs). The heterogeneity investigation was conducted utilizing I² measurement at α = 0.10. Out of 86 retrieval records, four articles met the inclusion criteria. Based on clinical and radiographic outcomes, the application of 3Mixtatin in the pulp therapy of primary teeth was as successful as MTA in 12 months (Clinical RR = 1.087 | Radiographic RR = 2.132). The RoB-2 tool showed a low risk of bias in all included RCTs. The limited evidence showed the clinical and radiographic efficacy of 3Mixtatin as a potential alternative to MTA. Further empirical research with larger sample sizes and strict methodology will be essential to substantiate this assertion.

Durability of Effects of Cognitive Remediation on Cognition and Psychosocial Functioning in Schizophrenia: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Cognitive remediation provides substantial improvements in cognitive performance and real-world functioning for people living with schizophrenia, but the durability of these benefits needs to be reassessed and better defined. The aims of this study were to provide a comprehensive assessment of the durability of the benefits of cognitive remediation for cognition and functioning in people living with schizophrenia and evaluating potential moderators of effects. A systematic search was conducted in PubMed, Scopus, and PsycINFO, and reference lists of included articles and Google Scholar were inspected. Eligible studies were randomized clinical trials of cognitive remediation in patients diagnosed with schizophrenia spectrum disorders in which follow-up assessments were included. Screening and data extraction were performed by at least two independent reviewers. Cohen's d was used to measure outcomes. Primary outcomes were changes in cognition and functioning from baseline to conclusion of follow-up. Moderators of the durability of effects were assessed. Of 2,840 identified reports, 281 full texts were assessed and 130 reports on 67 studies with 5,334 participants were included. Cognitive remediation produced statistically significant positive effects that persisted at the end of follow-up in global cognition (d=0.23) and in global functioning (d=0.26). Smaller study samples and single-center studies were associated with better cognitive outcomes; longer treatment and follow-up duration, techniques for transferring cognitive gains to the real world, integration with psychiatric rehabilitation, group format of delivery, and more female participants in the sample were associated with better functional outcomes. Cognitive remediation provides durable improvements in cognition and functioning in schizophrenia. This finding corroborates the notion that cognitive remediation should be implemented more widely in clinical and rehabilitation practice.

The role of trait reappraisal in response to emotional ambiguity: A systematic review and meta-analysis.

Individuals exhibit a systematic valence bias-a specific form of interpretation bias-in response to emotional ambiguity. Accumulating evidence suggests most people initially respond to emotional ambiguity negatively and differ only in subsequent responses. We hypothesized that trait-level cognitive reappraisal-an emotion regulation strategy involving the reinterpretation of affective meaning of stimuli-might explain individual differences in valence bias. To answer this question, we conducted a random-effects meta-analysis of 14 effect sizes from 13 prior studies (n = 2,086), identified via Google Scholar searches. We excluded studies (a) in languages other than English, (b) from non-peer-reviewed sources, or (c) nonempirical sources. We included studies with (a) the Emotion Regulation Questionnaire, (b) a putative measure of valence bias prior to any study-specific manipulations, and (c) adult human participants (i.e., 17+). Supporting our prediction, we found individuals with higher trait reappraisal exhibited a less negative bias (r = -.18, z = -4.04, p < .001), whereas there was a smaller, opposite effect for trait expressive suppression (r = .10, z = 2.14, p = .03). The effects did, however, vary across tasks with stronger effects observed among studies using the scrambled sentences task compared to the valence bias task. Although trait reappraisal accounted for only a small amount of variance, reappraisal may be one mechanism contributing to variability in response to ambiguity.

New Molecules of Importance in the Prevention and Treatment of Acne: A Systematic Patent Review (2016-2020).

Acne is a highly prevalent disease that mainly affects the pilosebaceous units associated with sebaceous glands, causing inflammatory skin lesions and affecting the self-esteem, mental health, and quality of life of those who suffer from this disease. Different treatments exist today to prevent, reduce, and improve symptoms; however, over the years, there have been problems with bacterial resistance and slight effectiveness with prolonged use. The purpose of this article is based on the review of patents of new products of principal topical administration for the treatment of acne in recent years 2016-2020, to evaluate and analyze novel synthetic molecules and semi-synthetics with potential therapeutic and preventive in the acne treatment. A systematic review of patents was conducted through the official database of the European Patent Office - Espacenet, where the search focused on the keywords: "acne and bacteria" in the title or abstract. Only patents granted between the years 2016-2020 were included, with products having molecules with a synthetic and semi-synthetic origin, without considering natural, biological products or those used as diagnostic means. A total of 19 patents were selected, most with principally antimicrobial and antiinflammatory action, where the reduction in the appearance of resistance by C. acnes is verified, and its action is complemented by inhibiting the different pathophysiological mechanisms that lead to the worsening of the disease. Novel approaches in the treatment and prevention of acne, mainly topically, are focused on the reduction of bacterial resistance and irritation compared to current treatments. The use of combined formulations provides better results with additional benefits, improving treatment times and patient adherence.

Review on Paclitaxel Derivatization: Enhanced Anticancer Action

Background: The United States Food and Drug Administration (FDA) has authorized paclitaxel for the treatment of numerous types of cancer, including breast, lung, ovarian, and Kaposi's sarcoma. It possesses all the characteristics of BCS class IV medications, including low bioavailability, low water solubility, poor permeability, unpredictable and poor absorption, and inter- and intrasubject variability. Objective: The purpose of this research was to evaluate previous efforts done to derivatize paclitaxel for greater effectiveness. Methods: A systematic literature review was conducted from a variety of sources, including published research, review articles, and patents, that mainly focus on the derivatization of paclitaxel that has been done in the last 10 years to enhance its solubility, permeability, and bioavailability. Different forms of derivatization were done in order to improve the drug's ability to be absorbed by the body, as well as its solubility and bioavailability. Results: This article explores the current and future strategies for increasing the anti-cancer efficacy of paclitaxel by enhancing its bioavailability, solubility, and penetration efficacy. Some examples are lipidbased delivery systems, polymer-based nanocarriers, crystal engineering (nanocrystals and co-crystals), liquidsolid technologies, and self-emulsifying solid dispersions. Other strategies are also discussed in this article. Conclusion: It is quite likely that this review article will contain perfect fragments of evidence for building a new model for the application of paclitaxel in the treatment of cancer.

Lean Six Sigma Studies in Türkiye: A Literature Review

The literature in the field of Lean Six Sigma (LSS) is developing in Türkiye as well as over the world. However, theses and papers written in Turkish are waiting to be disseminated. This paper aims to investigate LSS in the Turkish context with the purpose of identifying the current state, gaining insight and exploring future directions. This paper implements the systematic literature review methodology to identify and review all relevant studies in Turkish literature. This paper covers the literature on LSS in Türkiye from 2004 to 2021. As a result, a total of 32 theses and 29 papers were investigated in detail. This paper not only focuses on years, sectors, areas etc. of the studies, but also analyses the contents of papers in relation to enterprise size, project prioritization, and quality tools used in DMAIC phases, and improvements after implementation in terms of descriptive and content analysis. The results show that, although there are many LSS implementations in Turkish context, they could not be shared with global academic area due to the national language usage. LSS implementations have an increasing trend in last years and highly focused on manufacturing sector and large companies. The lack of structured way of applying LSS, especially not using project prioritization and selection methodology takes attention. This paper shows the gaps and future directions in Türkiye for researchers and provides a groundwork to develop a roadmap for Turkish organizations.
