Trauma-focused psychotherapy (tf-PT) is the first-line treatment for posttraumatic stress disorder (PTSD). Tf-PT focuses on processing and modulating trauma memories. Not all patients benefit, however, and there is room for improvement of efficacy. Pharmacologically augmenting trauma memory modulation in the context of tf-PT may help optimise treatment outcome. To systematically review effects of pharmacologically augmented memory modulation in the context of tf-PT for PTSD (PROSPERO preregistration ID: CRD42021230623). We conducted a systematic review of randomised controlled trials of psychotherapy treatment for PTSD. We included placebo-controlled studies that augmented at least one treatment session pharmacologically targeting memory extinction or reconsolidation. We calculated post-treatment between group (pharmacological augmentation vs placebo control) effect sizes of PTSD symptom severity. We included 13 RCTs. There was large heterogeneity in augmentation procedure and methodological quality. Four studies showed significantly greater PTSD symptom reduction in the pharmacological augmentation group (propranolol, hydrocortisone, dexamethasone, D-cycloserine) compared to placebo. Seven studies showed no significant effect of pharmacological augmentation compared to placebo (D-cycloserine, rapamycin, mifepristone, propranolol, mifepristone combined with D-cycloserine, methylene blue). Two studies showed significantly smaller PTSD symptom reduction in the pharmacological augmentation group (D-cycloserine, dexamethasone) compared to placebo. Results of pharmacological augmentation were mixed overall and heterogenous for the pharmacological agents tested in more than one study. Additional studies and replications are needed to identify which pharmacological agents work, in which combination and to identify patient groups that benefit most to tailor PTSD treatment.

Meta-Analysis Review
BACKGROUND
This is the second update of the original Cochrane review published in 2013 (issue 6), which was updated in 2016 (issue 11). Pruritus occurs in patients with disparate underlying diseases and is caused by different pathologic mechanisms. In palliative care patients, pruritus is not the most prevalent but is a burdening symptom. It can cause considerable discomfort and negatively affect patients' quality of life.
OBJECTIVES
To assess the effects of different pharmacological treatments compared with active control or placebo for preventing or treating pruritus in adult palliative care patients.
SEARCH METHODS
For this update, we searched CENTRAL (the Cochrane Library), MEDLINE (OVID) and Embase (OVID) up to 6 July 2022. In addition, we searched trial registries and checked the reference lists of all relevant studies, key textbooks, reviews and websites, and we contacted investigators and specialists in pruritus and palliative care regarding unpublished data.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) assessing the effects of different pharmacological treatments, compared with a placebo, no treatment, or an alternative treatment, for preventing or treating pruritus in palliative care patients.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed the identified titles and abstracts, performed data extraction and assessed the risk of bias and methodological quality. We summarised the results descriptively and quantitatively (meta-analyses) according to the different pharmacological interventions and the diseases associated with pruritus. We assessed the evidence using GRADE and created 13 summary of findings tables.
MAIN RESULTS
In total, we included 91 studies and 4652 participants in the review. We added 42 studies with 2839 participants for this update. Altogether, we included 51 different treatments for pruritus in four different patient groups. The overall risk of bias profile was heterogeneous and ranged from high to low risk. The main reason for giving a high risk of bias rating was a small sample size (fewer than 50 participants per treatment arm). Seventy-nine of 91 studies (87%) had fewer than 50 participants per treatment arm. Eight (9%) studies had low risk of bias in the specified key domains; the remaining studies had an unclear risk of bias (70 studies, 77%) or a high risk of bias (13 studies, 14%). Using GRADE criteria, we judged that the certainty of evidence for the primary outcome (i.e. pruritus) was high for kappa-opioid agonists compared to placebo and moderate for GABA-analogues compared to placebo. Certainty of evidence was low for naltrexone, fish-oil/omega-3 fatty acids, topical capsaicin, ondansetron and zinc sulphate compared to placebo and gabapentin compared to pregabalin, and very low for cromolyn sodium, paroxetine, montelukast, flumecinol, and rifampicin compared to placebo. We downgraded the certainty of the evidence mainly due to serious study limitations regarding risk of bias, imprecision, and inconsistency. For participants suffering from uraemic pruritus (UP; also known as chronic kidney disease (CKD)-associated pruritus (CKD-aP)), treatment with GABA-analogues compared to placebo likely resulted in a large reduction of pruritus (visual analogue scale (VAS) 0 to 10 cm): mean difference (MD) -5.10, 95% confidence interval (CI) -5.56 to -4.55; five RCTs, N = 297, certainty of evidence: moderate. Treatment with kappa-opioid receptor agonists (difelikefalin, nalbuphine, nalfurafine) compared to placebo reduced pruritus slightly (VAS 0 to 10 cm, MD -0.96, 95% CI -1.22 to -0.71; six RCTs, N = 1292, certainty of evidence: high); thus, this treatment was less effective than GABA-analogues. Treatment with montelukast compared to placebo may result in a reduction of pruritus, but the evidence is very uncertain (two studies, 87 participants): SMD -1.40, 95% CI -1.87 to -0.92; certainty of evidence: very low. Treatment with fish-oil/omega-3 fatty acids compared to placebo may result in a large reduction of pruritus (four studies, 160 observations): SMD -1.60, 95% CI -1.97 to -1.22; certainty of evidence: low. Treatment with cromolyn sodium compared to placebo may result in a reduction of pruritus, but the evidence is very uncertain (VAS 0 to 10 cm, MD -3.27, 95% CI -5.91 to -0.63; two RCTs, N = 100, certainty of evidence: very low). Treatment with topical capsaicin compared with placebo may result in a large reduction of pruritus (two studies; 112 participants): SMD -1.06, 95% CI -1.55 to -0.57; certainty of evidence: low. Ondansetron, zinc sulphate and several other treatments may not reduce pruritus in participants suffering from UP. In participants with cholestatic pruritus (CP), treatment with rifampicin compared to placebo may reduce pruritus, but the evidence is very uncertain (VAS: 0 to 100, MD -42.00, 95% CI -87.31 to 3.31; two RCTs, N = 42, certainty of evidence: very low). Treatment with flumecinol compared to placebo may reduce pruritus, but the evidence is very uncertain (RR > 1 favours treatment group; RR 2.32, 95% CI 0.54 to 10.1; two RCTs, N = 69, certainty of evidence: very low). Treatment with the opioid antagonist naltrexone compared to placebo may reduce pruritus (VAS: 0 to 10 cm, MD -2.42, 95% CI -3.90 to -0.94; two RCTs, N = 52, certainty of evidence: low). However, effects in participants with UP were inconclusive (percentage of difference -12.30%, 95% CI -25.82% to 1.22%, one RCT, N = 32). In palliative care participants with pruritus of a different nature, the treatment with the drug paroxetine (one study), a selective serotonin reuptake inhibitor, compared to placebo may reduce pruritus slightly by 0.78 (numerical analogue scale from 0 to 10 points; 95% CI -1.19 to -0.37; one RCT, N = 48, certainty of evidence: low). Most adverse events were mild or moderate. Two interventions showed multiple major adverse events (naltrexone and nalfurafine).
AUTHORS CONCLUSIONS
Different interventions (GABA-analogues, kappa-opioid receptor agonists, cromolyn sodium, montelukast, fish-oil/omega-3 fatty acids and topical capsaicin compared to placebo) were effective for uraemic pruritus. GABA-analogues had the largest effect on pruritus. Rifampin, naltrexone and flumecinol tended to be effective for cholestatic pruritus. However, therapies for patients with malignancies are still lacking. Due to the small sample sizes in most meta-analyses and the heterogeneous methodological quality of the included trials, the results should be interpreted cautiously in terms of generalisability.

Meta-Analysis Review
Pyrazinamide (PZA) is an essential first-line tuberculosis drug for its unique mechanism of action active against multidrug-resistant-TB (MDR-TB). Thus, the aim of updated meta-analysis was to estimate the PZA weighted pooled resistance (WPR) rate in M. tuberculosis isolates based on publication date and WHO regions. We systematically searched the related reports in PubMed, Scopus, and Embase (from January 2015 to July 2022). Statistical analyses were performed using STATA software. The 115 final reports in the analysis investigated phenotypic PZA resistance data. The WPR of PZA was 57% (95% CI 48-65%) in MDR-TB cases. According to the WHO regions, the higher WPRs of PZA were reported in the Western Pacific (32%; 95% CI 18-46%), South East Asian region (37%; 95% CI 31-43%), and the Eastern Mediterranean (78%; 95% CI 54-95%) among any-TB patients, high risk of MDR-TB patients, and MDR-TB patients, respectively. A negligible increase in the rate of PZA resistance were showed in MDR-TB cases (55% to 58%). The rate of PZA resistance has been rising in recent years among MDR-TB cases, underlines the essential for both standard and novel drug regimens development.

Meta-Analysis
OBJECTIVE
The GeneXpert MTB/RIF assay (Xpert) is a diagnostic tool that has been shown to significantly improve the accuracy of tuberculosis (TB) detection in clinical settings, with advanced sensitivity and specificity. Early detection of TB can be challenging, but Xpert has improved the efficacy of the diagnostic process. Nevertheless, the accuracy of Xpert varies according to different diagnostic specimens and TB infection sites. Therefore, the selection of adequate specimens is critical when using Xpert to identify suspected TB. As such, we have conducted a meta-analysis to evaluate the effectiveness of Xpert for diagnosis of different TB types using several specimens.
METHODS
We conducted a comprehensive search of several electronic databases, including PubMed, Embase, the Cochrane Central Register of Controlled Trials, and the World Health Organization clinical trials registry center, covering studies published from Jan 2008 to July 2022. Data were extracted using an adapted version of the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modeling Studies. Where appropriate, meta-analysis was performed using random-effects models. The risk of bias and level of evidence was assessed using the Quality in Prognosis Studies tool and a modified version of the Grading of Recommendations Assessment, Development, and Evaluation. RStudio was utilized to analyze the results, employing the , , and packages.
RESULTS
After excluding duplicates, a total of 2163 studies were identified, and ultimately, 144 studies from 107 articles were included in the meta-analysis based on predetermined inclusion and exclusion criteria. Sensitivity, specificity and diagnostic accuracy were estimated for various specimens and TB types. In the case of pulmonary TB, Xpert using sputum (0.95 95%CI 0.91-0.98) and gastric juice (0.94 95%CI 0.84-0.99) demonstrated similarly high sensitivity, surpassing other specimen types. Additionally, Xpert exhibited high specificity for detecting TB across all specimen types. For bone and joint TB, Xpert, based on both biopsy and joint fluid specimens, demonstrated high accuracy in TB detection. Furthermore, Xpert effectively detected unclassified extrapulmonary TB and tuberculosis lymphadenitis. However, the Xpert accuracy was not satisfactory to distinguish TB meningitis, tuberculous pleuritis and unclassified TB.
CONCLUSIONS
Xpert has exhibited satisfactory diagnostic accuracy for most TB infections, but the efficacy of detection may vary depending on the specimens analyzed. Therefore, selecting appropriate specimens for Xpert analysis is essential, as using inadequate specimens can reduce the ability to distinguish TB.

Meta-Analysis Review
Evaluation of genetic mutations associated with phenotypic resistance to fluoroquinolones, bedaquiline, and linezolid in clinical Mycobacterium tuberculosis: A systematic review and meta-analysis.
OBJECTIVES
The aim of the study was to update the classification of drugs used in multidrug-resistant tuberculosis (MDR-TB) regimens. Group A drugs (fluoroquinolones, bedaquiline (BDQ), and linezolid (LZD)) are crucial drugs for the control of MDR-TB. Molecular drug resistance assays could facilitate the effective use of Group A drugs.
METHODS
We summarised the evidence implicating specific genetic mutations in resistance to Group A drugs. We searched PubMed, Embase, MEDLINE, and the Cochrane Library for studies published from the inception of each database until July 1, 2022. Using a random-effects model, we calculated the odds ratios and 95% confidence intervals as our measures of association.
RESULTS
A total of 5001 clinical isolates were included in 47 studies. Mutations in gyrA A90V, D94G, D94N, and D94Y were significantly associated with an increased risk of a levofloxacin (LFX)-resistant phenotype. In addition, mutations in gyrA G88C, A90V, D94G, D94H, D94N, and D94Y were significantly associated with an increased risk of a moxifloxacin (MFX)-resistant phenotype. In only one study, the majority of gene loci (n = 126, 90.65%) in BDQ-resistant isolates were observed to have unique mutations in atpE, Rv0678, mmpL5, pepQ, and Rv1979c. The most common mutations occurred at four sites in the rrl gene (g2061t, g2270c, g2270t, and g2814t) and at one site in rplC (C154R) in LZD-resistant isolates. Our meta-analysis demonstrated that there were no mutations associated with BDQ- or LZD-resistant phenotypes.
CONCLUSION
The mutations detected by rapid molecular assay were correlated with phenotypic resistance to LFX and MFX. The absence of mutation-phenotype associations for BDQ and LZD hindered the development of a rapid molecular assay.

We performed an analysis of the cost and relative merits of different strategies for the diagnosis of multidrug-resistant/extensively drug-resistant TB (MDR/XDR-TB) in different settings. We systematically reviewed the published evidence on cost/cost-effectiveness of rapid MDR/pre-XDR-TB and other methods for XDR-TB testing up to September 2022. PRISMA guidelines were followed. Collected data were analysed using Stata v17 software. Cost data were reported in USD ($) and summarised by mean, standard deviation, and range. Country income level was defined according to the World Bank country classification. Three simplified scenarios were also used to explore testing implications, based on low, intermediate and high TB incidence. Of 157 records, 25 studies were included with 24 reporting the cost of Xpert/RIF and two that evaluated the implementation of the MTBDR test. The total rapid test cost ranged from $12.41-$218, including $1.13-$74.60 for reagents/consumables and $0.40-$14.34 for equipment. The cost of MDR/XDR-TB diagnostics is lower in low resource settings. However, the cost-effective implementation of MDR/XDR-TB diagnostic algorithms requires careful consideration of local resources to avoid missed identification and the use of inappropriate regimen.

Meta-Analysis
IMPORTANCE
Latent tuberculosis infection (LTBI) can progress to active tuberculosis disease, causing morbidity and mortality.
OBJECTIVE
To review the evidence on benefits and harms of screening for and treatment of LTBI in adults to inform the US Preventive Services Task Force (USPSTF).
DATA SOURCES
PubMed/MEDLINE, Cochrane Library, and trial registries through December 3, 2021; references; experts; literature surveillance through January 20, 2023.
STUDY SELECTION
English-language studies of LTBI screening, LTBI treatment, or accuracy of the tuberculin skin test (TST) or interferon-gamma release assays (IGRAs). Studies of LTBI screening and treatment for public health surveillance or disease management were excluded.
DATA EXTRACTION AND SYNTHESIS
Dual review of abstracts, full-text articles, and study quality; qualitative synthesis of findings; meta-analyses conducted when a sufficient number of similar studies were available.
MAIN OUTCOMES AND MEASURES
Screening test accuracy; development of active tuberculosis disease, transmission, quality of life, mortality, and harms.
RESULTS
A total of 113 publications were included (112 studies; N = 69 009). No studies directly evaluated the benefits and harms of screening. Pooled estimates for sensitivity of the TST were 0.80 (95% CI, 0.74-0.87) at the 5-mm induration threshold, 0.81 (95% CI, 0.76-0.87) at the 10-mm threshold, and 0.60 (95% CI, 0.46-0.74) at the 15-mm threshold. Pooled estimates for sensitivity of IGRA tests ranged from 0.81 (95% CI, 0.79-0.84) to 0.90 (95% CI, 0.87-0.92). Pooled estimates for specificity of screening tests ranged from 0.95 to 0.99. For treatment of LTBI, a large (n = 27 830), good-quality randomized clinical trial found a relative risk (RR) for progression to active tuberculosis at 5 years of 0.35 (95% CI, 0.24-0.52) for 24 weeks of isoniazid compared with placebo (number needed to treat, 112) and an increase in hepatotoxicity (RR, 4.59 [95% CI, 2.03-10.39]; number needed to harm, 279). A previously published meta-analysis reported that multiple regimens were efficacious compared with placebo or no treatment. Meta-analysis found greater risk for hepatotoxicity with isoniazid than with rifampin (pooled RR, 4.22 [95% CI, 2.21-8.06]; n = 7339).
CONCLUSIONS AND RELEVANCE
No studies directly evaluated the benefits and harms of screening for LTBI compared with no screening. TST and IGRAs were moderately sensitive and highly specific. Treatment of LTBI with recommended regimens reduced the risk of progression to active tuberculosis. Isoniazid was associated with higher rates of hepatotoxicity than placebo or rifampin.

Meta-Analysis
BACKGROUND
Tuberculosis preventative therapy (TPT) is a key part of the World Health Organization's (WHO) end tuberculosis (TB) strategy. However, the occurrence of potentially serious adverse events (AE) is a limitation of TPT regimens. We conducted a systemic review and meta-analysis to estimate the incidence of AE and hepatotoxicity with various TPT regimens to help inform clinical decision making.
METHODS
We searched MEDLINE, Cochrane, Health Star, and EMBASE from 1952 to April 2021 for studies reporting AE associated with TPT. Included studies reported AE stratified by regimen and provided the number of participants receiving each regimen. We used a random-effect model to meta-analyze the cumulative incidence of AE.
RESULTS
We included 175 publications describing TPT-related AE in 277 cohorts. Among adults, the incidence of any AE, and hepatotoxicity leading to drug discontinuation was 3.7% and 1.1%, respectively, compared to 0.4% and 0.02%, respectively, in children. The highest incidence of any AE, and AE leading to drug discontinuation was with 3 months isoniazid and rifapentine (3HP), and the lowest was with 4 months rifampin (4R). 4R also had the lowest incidence of hepato-toxic AE and drug discontinuation due to hepato-toxic AE. 3HP also had a low incidence of hepato-toxic AE.
CONCLUSIONS
Although our study was limited by variability in methods and quality of AE reporting in the studies reviewed, pediatric populations had a very low incidence of AE with all TPT regimens reviewed. In adults, compared to mono-H regimens all rifamycin-based regimens were safer, although 4R had the lowest incidence of TPT-related AE of all types and of hepatotoxicity.

Meta-Analysis
IMPORTANCE
Calciphylaxis is a rare disease with high mortality mainly involving patients with chronic kidney disease (CKD). Sodium thiosulphate (STS) has been used as an off-label therapeutic in calciphylaxis, but there is a lack of clinical trials and studies that demonstrate its effect compared with those without STS treatment.
OBJECTIVE
To perform a meta-analysis of the cohort studies that provided data comparing outcomes among patients with calciphylaxis treated with and without intravenous STS.
DATA SOURCES
PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov were searched using relevant terms and synonyms including sodium thiosulphate and calci* without language restriction.
STUDY SELECTION
The initial search was for cohort studies published before August 31, 2021, that included adult patients diagnosed with CKD experiencing calciphylaxis and could provide a comparison between patients treated with and without intravenous STS. Studies were excluded if they reported outcomes only from nonintravenous administration of STS or if the outcomes for CKD patients were not provided.
DATA EXTRACTION AND SYNTHESIS
Random-effects models were performed. The Egger test was used to measure publication bias. Heterogeneity was assessed using the I2 test.
MAIN OUTCOMES AND MEASURES
Skin lesion improvement and survival, synthesized as ratio data by a random-effects empirical Bayes model.
RESULTS
Among the 5601 publications retrieved from the targeted databases, 19 retrospective cohort studies including 422 patients (mean age, 57 years; 37.3% male) met the eligibility criteria. No difference was observed in skin lesion improvement (12 studies with 110 patients; risk ratio, 1.23; 95% CI, 0.85-1.78) between the STS and the comparator groups. No difference was noted for the risk of death (15 studies with 158 patients; risk ratio, 0.88; 95% CI, 0.70-1.10) and overall survival using time-to-event data (3 studies with 269 participants; hazard ratio, 0.82; 95% CI, 0.57-1.18). In meta-regression, lesion improvement associated with STS negatively correlated with publication year, implying that recent studies are more likely to report a null association compared with past studies (coefficient = -0.14; P = .008).
CONCLUSIONS AND RELEVANCE
Intravenous STS was not associated with skin lesion improvement or survival benefit in patients with CKD experiencing calciphylaxis. Future investigations are warranted to examine the efficacy and safety of therapies for patients with calciphylaxis.

Meta-Analysis Review
BACKGROUND
Several studies have investigated the safety and efficacy of antimicrobial peripherally inserted central catheters (PICCs), and the results are conflicting. Therefore, in this systematic review and meta-analysis, we aimed to summarize and identify the effect of antimicrobial PICCs on central line-associated bloodstream infection (CLABSI) risk.
METHODS
A systematic search of PubMed, Ovid MEDLINE, Ovid Embase, and Web of Science was performed to identify relevant studies up to December 2022.
RESULTS
A total of 9 studies were included for analysis. There were 7 retrospective/prospective cohort studies and 2 randomized controlled trials. The 9 studies involved 51,373 patients with PICCs. Among these patients, 6,563 (12.8%) antimicrobial-coated/impregnated PICCs and 44,810 (87.2%) nonantimicrobial-impregnated PICCs were inserted. The meta-analysis showed that antimicrobial PICCs had a nonsignificant association with lower CLABSI risk compared with noncoated PICCs (relative risk [RR] = 0.67; 95% CI, 0.43-1.05). In the subgroup analysis, minocycline-rifampin-(RR = 0.30; 95% CI, 0.19-0.49) or chlorhexidine-coated (RR = 0.61; 95% CI, 0.04-8.55) PICCs showed an association with reduced risk of CLABSI. In the adult population, antimicrobial PICCs had a nonsignificant association with lower CLABSI risk (RR = 0.50; 95% CI, 0.20-1.22).
CONCLUSIONS
This systematic review and meta-analysis suggested that antimicrobial PICCs had a nonsignificant association with lower CLABSI risk compared with noncoated PICCs. Minocycline-rifampin-or chlorhexidine-coated PICCs showed an association with reduced risk of CLABSI.
