Meta-Analysis Review
OBJECTIVE
To systematically appraise the existing published literature on cervical cancer screening utilization, and associated barriers and facilitators, in Nepal.
STUDY DESIGN
Systematic literature review and meta-analysis.
METHODS
PubMed/MEDLINE, CINAHL, Scopus, Embase, and, Google Scholar were systematically searched using Preferred Reporting Items for Systematic Review and Meta-Analysis guideline. All quantitative and qualitative studies reporting cervical cancer screening (using the Pap smear test or visual inspection with acetic acid or human papillomavirus test) utilization, barriers, and facilitators for screening were identified. A meta-analysis was performed to estimate Nepal's pooled cervical cancer screening utilization proportion.
RESULTS
The search yielded 97 records, of which 17 studies were included. Fifteen studies were quantitative and two were qualitative. Of the 17 studies, six were hospital-based and six were community-based. The pooled cervical cancer screening utilization proportion (using Pap smear test) among Nepalese women was 17% from the studies in the hospital settings, and 16% in the community. Six studies reported barriers to cervical cancer screening, of which four reported embarrassments related to the gynecological examination and a low level of knowledge on cervical cancer. Three (of four) studies reported health personnel, and two studies reported screening services-related facilitators for cervical cancer screening.
CONCLUSION
Our review reported that cervical cancer screening utilization (16%) is more than four times lower than the national target (70%) in Nepal. Multiple barriers such as low levels of knowledge and embarrassment are associated with cervical cancer screening utilization. Health personnel's gender, counseling, and privacy of screening services were commonly reported facilitators. These findings could help to inform future research, and policy efforts to increase cervical cancer screening utilization in Nepal.

World Journal of Pediatrics : WJP Feb 2023We aimed to evaluate the tolerability and efficacy of linezolid in children for treating suspected and diagnosed Gram-positive bacterial infections. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
We aimed to evaluate the tolerability and efficacy of linezolid in children for treating suspected and diagnosed Gram-positive bacterial infections.
METHODS
A systematic literature search was conducted up to April 23, 2021, using linezolid and its synonyms as search terms. Two reviewers independently identified and extracted relevant randomized controlled trials and prospective cohort studies. The extracted studies were included in a single-rate meta-analysis of adverse events and clinical outcomes using random-effects models.
RESULTS
A total of 1082 articles were identified, and nine studies involving 758 children were included in the meta-analysis. The overall proportion of adverse events was 8.91% [95% confidence interval (CI) = 1.64%-36.52%], with diarrhea (2.24%), vomiting (2.05%), and rash (1.72%) being the most common. The incidences of thrombocytopenia and anemia were 0.68% and 0.16%, respectively. Some specific adverse events, including rash and gastrointestinal events, were more frequent in the oral administration subgroup. In terms of efficacy, the overall proportion of clinical improvement was 88.80% (95% CI = 81.31%-93.52%). Children with a history of specific bacteriological diagnosis or concomitant antibiotic therapy had a 1.13-fold higher clinical improvement than children without such histories. The proportion of microbial eradication was 92.68% (95% CI = 84.66%-96.68%). The proportion of all-cause mortality was 0.16% (95% CI = 0.00%-7.75%).
CONCLUSIONS
Linezolid was well-tolerated in pediatric patients and was associated with a low frequency of adverse events, such as anemia, thrombocytopenia, and neutropenia. Moreover, linezolid was effective in children with diagnosed and suspected Gram-positive infections.

Meta-Analysis Review
This Cochrane Review was withdrawn in April 2015, and this withdrawal notice was updated in September 2016. The review was withdrawn as result of comments submitted via the Cochrane Library by Harri Hemilä in February 2015. Hemilä identified multiple errors in this Cochrane Review and made allegations of plagiarism of text and data from a previously published systematic review (Hemilä H. Zinc Lozenges may shorten the duration of colds: a systematic review. 2011;5:51‐58. dx.doi.org/10.2174/1874306401105010051). The comments referred to the version of this review first published in June 2013 (Singh M, Das RR. Zinc for the common cold. 2013;(6):CD001364. http://onlinelibrary.wiley.com/doi/10.1002/14651858.CD001364.pub4/full). The Cochrane Acute Respiratory Infections Group, which maintains the review, withdrew the review in April 2015, pending an assessment of the errors reported, and the group referred the allegations of plagiarism to the Editor in Chief. The Editor in Chief notified the authors of the concerns, and followed the Committee for Publication Ethics (COPE) guidelines. Replication of text was identified in the Cochrane Review. This was limited to copying of short phrases and was acknowledged by the authors. The level of text plagiarism was minor and at a level that would be addressed by a correction. The Editor in Chief carried out further investigation into the alleged plagiarism of data, with the co‐operation of the review authors, who provided supplementary information in support of their work. The allegations related to the derivation of means and standard deviations of data from some of the included studies. Although the authors acknowledge and cite the Hemilä 2011 review, the Editor in Chief considered that the authors’ explanation regarding some similarities in presented data between the two reviews was not conclusive. This version of the review will therefore remain withdrawn. This review was withdrawn due to concerns raised via the feedback mechanism regarding the calculation and analysis of data in the review in April 2015. Whilst it is not unusual for reviews to be withdrawn, the editorial group took the view that it would be better to take a cautious approach and explore the source and calculation of data used in the analysis in more detail, rather than keep the review on the Cochrane Database of Systematic Reviews for the time being. The editorial group responsible for this previously published document have withdrawn it from publication.

Review
This systematic review aimed to compare the efficacy of herbal agents with ethylene diamine tetraacetic acid (EDTA) in removing the smear layer during root canal instrumentation. The research question in the present study was to assess: "Is there a significant difference in reducing smear layer comparing EDTA and herbal agents?" Electronic databases (PubMed, Scopus, and Web of Science) were searched from their start dates to April 2022 using strict inclusion and exclusion criteria, and reviewed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 guidelines. Only in vitro studies comparing herbal agents with EDTA were included in the current systematic review. Two reviewers independently assessed the included articles. A total of 625 articles were obtained from an electronic database. Eighteen papers were included for review of the full text, out of which, ten papers were excluded because they did not meet the inclusion criteria. Finally, eight articles were included in the systematic review. The present systematic review considered only in vitro studies; hence, the result cannot be completely translated to strict clinical conditions. The results of the present systematic review have shown that extract, and neem show better smear layer removal compared to other herbal agents, whereas they showed reduced smear layer removal when compared with EDTA. Although, it was seen that most of the included studies did not report a high quality of evidence. Hence, the present systematic review concludes that herbal agents have reported to show inferior smear layer removal when compared to EDTA. Thus, as far as herbal based alternatives are concerned, there is no highest level of evidence to state its real benefit when used as a chelating root canal irrigant.

BACKGROUND AND OBJECTIVES
Early life epilepsies are common and often debilitating, but no evidence-based management guidelines exist outside of those for infantile spasms. We conducted a systematic review of the effectiveness and harms of pharmacologic and dietary treatments for epilepsy in children aged 1-36 months without infantile spasms.
METHODS
We searched EMBASE, MEDLINE, PubMed, and the Cochrane Library for studies published from January 1, 1999, to August 19, 2021. Using prespecified criteria, we identified studies reporting data on children aged 1-36 months receiving pharmacologic or dietary treatments for epilepsy. We did not require that studies report etiology-specific data. We excluded studies of neonates, infantile spasms, and status epilepticus. We included studies administering 1 of 29 pharmacologic treatments and/or 1 of 5 dietary treatments reporting effectiveness outcomes at ≥ 12 weeks. We reviewed the full text to find any subgroup analyses of children aged 1-36 months.
RESULTS
Twenty-three studies met inclusion criteria (6 randomized studies, 2 nonrandomized comparative studies, and 15 prestudies/poststudies). All conclusions were rated low strength of evidence. Levetiracetam leads to seizure freedom in some infants (32% and 66% in studies reporting seizure freedom), but data on 6 other medications were insufficient to permit conclusions about effectiveness (topiramate, lamotrigine, phenytoin, vigabatrin, rufinamide, and stiripentol). Three medications (levetiracetam, topiramate, and lamotrigine) were rarely discontinued because of adverse effects, and severe events were rare. For diets, the ketogenic diet leads to seizure freedom in some infants (rates 12%-37%), and both the ketogenic diet and modified Atkins diet reduce average seizure frequency, but reductions are greater with the ketogenic diet (1 RCT reported a 71% frequency reduction at 6 months for ketogenic diet vs only a 28% reduction for the modified Atkins diet). Dietary harms were not well-reported.
DISCUSSION
Little high-quality evidence exists on pharmacologic and dietary treatments for early life epilepsies. Future research should isolate how treatments contribute to outcomes, conduct etiology-specific analyses, and report patient-centered outcomes such as hospitalization, neurodevelopment, functional performance, sleep quality, and patient and caregiver quality of life.

Meta-Analysis Review
BACKGROUND
Bronchiectasis is predominantly an acquired disease process that represents the end stage of a variety of unrelated pulmonary insults. It is defined as persistent irreversible dilatation and distortion of medium-sized bronchi. It has been suggested that with widespread use of high-resolution computed tomography, more bronchiectasis diagnoses are being made. Patients diagnosed with bronchiectasis frequently have difficulty expectorating sputum. Sputum therefore is retained in the lungs and may become infected, leading to further lung damage. Mucolytic agents target hypersecretion or changed physiochemical properties of sputum to make it easier to clear. One drug, recombinant human DNase, breaks down the DNA that is released at the site of infection by neutrophils.Mucus clearance along with antimicrobial therapy remains an integral part of bronchiectasis management. Chest physiotherapy along with mucolytic agents is commonly used in practice without clear supportive evidence.
OBJECTIVES
To determine whether ingested or inhaled mucolytics are effective in the treatment of patients with bronchiectasis.
SEARCH METHODS
We searched the Cochrane Airways Group Specialised Register and reference lists of relevant articles. We contacted experts in the field and drug companies. Searches were current as of June 2013.
SELECTION CRITERIA
Randomised trials of mucolytic treatment in people with bronchiectasis but not cystic fibrosis.
DATA COLLECTION AND ANALYSIS
Data extraction was performed independently by two review authors. Study authors were contacted for confirmation.
MAIN RESULTS
Four trials (with a combined total of 528 adult participants) were included, but almost none of the data from these studies could be aggregated in a meta-analysis.One trial (with 88 participants) compared bromhexine versus placebo. Compared with placebo, high doses of bromhexine with antibiotics eased difficulty in expectoration (mean difference (MD) -0.53, 95% confidence interval (CI) -0.81 to -0.25 at 16 days); the quality of the evidence was rated as low. A reduction in sputum production was noted with bromhexine (MD -21.5%, 95% CI -38.9 to -4.1 at day 16); again the quality of the evidence was rated as low. No significant differences between bromhexine and placebo were observed with respect to reported adverse events (odds ratio (OR) 2.93; 95% CI 0.12 to 73.97), and again the quality of the evidence was rated as low.In a single small, blinded but not placebo-controlled trial of older (> 55 years) participants with stable bronchiectasis and mucus hypersecretion, erdosteine combined with physiotherapy over a 15-day period improved spirometry and sputum purulence more effectively compared with physiotherapy alone. The spirometric improvement was small (MD 200 mL in forced expiratory volume in one second (FEV1) and 300 mL in forced vital capacity (FVC)) and was apparent only at day 15, not at earlier time points.The remaining two studies (with a combined total of 410 participants) compared recombinant human DNase (RhDNase) versus placebo. These two studies were very different (one was a two-week study of 61 participants, and the other ran for 24 weeks and included 349 participants), and the opportunity for combining data from the two studies was very limited. Compared with placebo, recombinant human DNase showed no difference in FEV1 or FVC in the smaller study but showed a significant negative effect on FEV1 in the larger and longer study. For reported adverse events, no significant differences between recombinant human DNase and placebo were noted. In all of the above comparisons of recombinant human DNase versus placebo, the quality of the evidence was judged to be low.
AUTHORS' CONCLUSIONS
Given the harmful effects of recombinant human DNase in one trial and no evidence of benefit, this drug should be avoided in non-cystic fibrosis bronchiectasis, except in the context of clinical trials. Evidence is insufficient to permit evaluation of the routine use of other mucolytics for bronchiectasis. High doses of bromhexine coupled with antibiotics may help with sputum production and clearance, but long-term data and robust clinical outcomes are lacking. Similarly, erdosteine may be a useful adjunct to physiotherapy in stable patients with mucus hypersecretion, but robust longer-term trials are required.Generally, clinical trials in children on the use of various mucolytic agents are lacking. As the number of agents available on the market, such as RhDNase, acetylcysteine and bromhexine, is increasing, improvement of the evidence base is needed.

OBJECTIVE
The aims of this systematic review were to (1) identify primary- and model-based economic evaluations of cervical cancer screening methods and to (2) provide a contextual summary of valuation outcomes associated with three types of cervical cancer screening tests: visual inspection with acetic acid, human papillomavirus deoxyribonucleic acid, and Papanicolaou smear.
INTRODUCTION
Cervical cancer screening is an important public health priority with the potential to improve the detection of precancerous lesions in high-risk females for early intervention and disease prevention. Test performance and cost-effectiveness differ based on the specific screening method used across different platforms. There is a need to appraise existing economic evaluations of cervical cancer screening methods.
METHODS
This review considered primary-based and model-based full economic evaluations of cervical cancer screening methods. The evaluation methods of interest included cost-effectiveness analysis, cost-utility analysis, cost-minimization analysis, cost-benefit analysis, and cost-consequence analysis. We searched Scopus, PubMed, National Health Economic Evaluation Database (NH EED), Cochrane, and the Health Economic Evaluation Database for full economic evaluations of cancer screening methods. No formal date restrictions were applied. Model-based and primary-based full economic evaluations were included. A critical appraisal of included studies was performed by the main investigator, while a second independent reviewer assessed critical appraisal findings for any inconsistencies. Data were extracted using a standardised data extraction tool for economic evaluations. The ultimate outcomes of costs, effectiveness, benefits, and utilities of cervical cancer screening modalities were extracted from included studies, analysed, and summarised.
RESULTS
From a total of 671 screened studies, 44 studies met the study inclusion criteria. Forty-three studies were cost-effectiveness analyses, one study reported both cost-utility and cost-effectiveness outcomes, and another study reported cost utilities of cervical cancer screening methods only. Human papillomavirus (HPV) DNA testing was reported as a dominant stand-alone screening test by 14 studies, while five studies reported visual inspection with acetic acid (VIA) as a dominant stand-alone screening test. Primary HPV screening strategies were dominant in 21 studies, while three studies reported cytology-based screening strategies as the dominant screening method.
CONCLUSIONS
Existing evidence indicates that HPV-based and VIA testing strategies are cost-effective, but this is dependent on setting. Our review suggests the limited cost-effectiveness of cytology-based testing, which may be due in part to the need for specific infrastructures and human resources.

INTRODUCTION
The development of the field related to the treatment of wounds has resulted in the appearance of new antimicrobial active ingredients.
AIM
To analyse, evaluate and systematize the available scientific evidence of the effectiveness and safety of antiseptic preparations intended for the treatment of chronic wounds.
MATERIAL AND METHODS
We conducted a literature review using the advanced search engine in the PubMed database. We used a combination of two English keywords, i.e.: "antiseptic" and "chronic wound". We have selected only clinical, randomized controlled trials.
RESULTS
We obtained a total of 825 items (674 full-text works). We included 29 studies in the review. The most frequently evaluated preparation was octenidine dihydrochloride and povidone iodine (pharmacological drugs). Preparations containing polyhexanide, products based on hypochlorite, reactive oxygen species, 1% acetic acid, and specialized antibacterial dressings were also assessed. The new generation of antimicrobial preparations were highly effective, both in the prevention and treatment of infections, and were well tolerated by the tissues and do not interfere with the healing process. The best tolerated and most effective antiseptic was OCT/PE. For cleaning, we recommend OCT-based irrigation fluids, PHMB, or hypochlorite. The maintenance of the antimicrobial effect during the therapy was ensured by a compatible dressing.
CONCLUSIONS
An antiseptic alone is not effective enough and the therapeutic effect depends to the greatest extent on properly selected causal therapy, preceded by thorough diagnostics.

Review
BACKGROUND
Any type of seizure can be observed in Alzheimer's disease (AD). Antiepileptic drugs seem to prevent the recurrence of epileptic seizures in most people with AD. There are pharmacological and non-pharmacological treatments for epilepsy in people with AD. There are no current systematic reviews to evaluate the efficacy and tolerability of the treatment. This review aims to review those different modalities.
OBJECTIVES
To assess the efficacy and tolerability of the treatment of epilepsy for people with Alzheimer's disease (AD) (including sporadic AD and dominantly inherited AD).
SEARCH METHODS
We searched the Cochrane Epilepsy Group Specialized Register (1 February 2016), the Cochrane Central Register of Controlled Trials (1 February 2016), MEDLINE (Ovid, 1 February 2016) and ClinicalTrials.gov (1 February 2016). In an effort to identify further published, unpublished and ongoing trials, we searched ongoing trials' registers, reference lists and relevant conference proceedings, and contacted authors and pharmaceutical companies.
SELECTION CRITERIA
We included randomised and quasi-randomised controlled trials investigating treatment for epilepsy in people with AD, with the outcomes of proportion of seizure freedom or experiencing adverse events.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened the titles and abstracts of identified records, selected studies for inclusion, extracted data, cross-checked the data for accuracy and assessed the methodological quality. We performed no meta-analyses due to the limited available data.
MAIN RESULTS
We included one randomised controlled trial with 95 participants. Concerning the proportion of participants with seizure freedom, no significant differences were found in levetiracetam (LEV) versus lamotrigine (LTG) (risk ratio (RR) 1.20, 95% confidence interval (CI) 0.53 to 2.71), in levetiracetam versus phenobarbital (PB) (RR 1.01, 95% CI 0.47 to 2.19), or in LTG versus PB (RR 0.84, 95% CI 0.35 to 2.02). It seemed that LEV could improve cognition and LTG could relieve depression; while PB and LTG could worsen cognition, and LEV and PB could worsen mood. We judged the quality of the evidence to be very low.
AUTHORS' CONCLUSIONS
This review does not provide sufficient evidence to support LEV, PB and LTG for the treatment of epilepsy in people with AD. Regarding the efficacy and tolerability, no significant differences were found between LEV, PB and LTG. In the future, large randomised, double-blind, controlled, parallel-group clinical trials are required to determine the efficacy and tolerability of treatment for epilepsy in people with AD.

Meta-Analysis
BACKGROUND
The beneficial role of gut microbiota and bacterial metabolites, including short-chain fatty acids (SCFAs), is well recognized, although the available literature around their role in colorectal cancer (CRC) has been inconsistent.
METHODS
We performed a systematic review and meta-analysis to examine the associations of fecal SCFA concentrations to the incidence and risk of CRC. Data extraction through Medline, Embase, and Web of Science was carried out from database conception to June 29, 2022. Predefined inclusion/exclusion criteria led to the selection of 17 case-control and six cross-sectional studies for quality assessment and analyses. Studies were categorized for CRC risk or incidence, and RevMan 5.4 was used to perform the meta-analyses. Standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated using a random-effects model. Studies lacking quantitation were included in qualitative analyses.
RESULTS
Combined analysis of acetic, propionic, and butyric acid revealed significantly lower concentrations of these SCFAs in individuals with a high-risk of CRC (SMD = 2.02, 95% CI 0.31 to 3.74, P = 0.02). Additionally, CRC incidence was higher in individuals with lower levels of SCFAs (SMD = 0.45, 95% CI 0.19 to 0.72, P = 0.0009), compared to healthy individuals. Qualitative analyses identified 70.4% of studies reporting significantly lower concentrations of fecal acetic, propionic, butyric acid, or total SCFAs in those at higher risk of CRC, while 66.7% reported significantly lower concentrations of fecal acetic and butyric acid in CRC patients compared to healthy controls.
CONCLUSIONS
Overall, lower fecal concentrations of the three major SCFAs are associated with higher risk of CRC and incidence of CRC.
