Meta-Analysis
Adverse perinatal outcomes associated with prenatal exposure to protease-inhibitor-based versus non-nucleoside reverse transcriptase inhibitor-based antiretroviral combinations in pregnant women with HIV infection: a systematic review and meta-analysis.
BACKGROUND
About 1.3 million pregnant women lived with HIV and were eligible to receive antiretroviral therapy (ART) worldwide in 2021. The World Health Organization recommends protease inhibitors (PI)-based regimen as second or third-line during pregnancy. With remaining pregnant women exposed to PIs, there is still an interest to assess whether this treatment affects perinatal outcomes. Adverse perinatal outcomes after prenatal exposure to PI-based ART remain conflicting: some studies report an increased risk of preterm birth (PTB) and low-birth-weight (LBW), while others do not find these results. We assessed adverse perinatal outcomes associated with prenatal exposure to PI-based compared with non-nucleoside reverse transcriptase (NNRTI)-based ART.
METHODS
We performed a systematic review searching PubMed, Reprotox, Clinical Trial Registry (clinicaltrials.gov) and abstracts of HIV conferences between 01/01/2002 and 29/10/2021. We used Oxford and Newcastle-Ottawa scales to assess the methodological quality. Studied perinatal outcomes were spontaneous abortion, stillbirth, congenital abnormalities, PTB (< 37 weeks of gestation), very preterm birth (VPTB, < 32 weeks of gestation), LBW (< 2500 grs), very low-birth-weight (VLBW, < 1500 g), small for gestational age (SGA) and very small for gestational age (VSGA). The association between prenatal exposure to PI-based compared to NNRTI-based ART was measured for each adverse perinatal outcome using random-effect meta-analysis to estimate pooled relative risks (RR) and their corresponding 95% confidence intervals (CI). Pre-specified analyses were stratified according to country income and study quality assessment, and summarized when homogeneous.
RESULTS
Out of the 49,171 citations identified, our systematic review included 32 published studies, assessing 45,427 pregnant women. There was no significant association between prenatal exposure to PIs compared to NNRTIs for VPTB, LBW, SGA, stillbirth, and congenital abnormalities. However, it was inconclusive for PTB, and PI-based ART is significantly associated with an increased risk of VSGA (sRR 1.41 [1.08-1.84]; I = 0%) compared to NNRTIs.
CONCLUSIONS
We did not report any significant association between prenatal exposure to PIs vs NNRTIs-based regimens for most of the adverse perinatal outcomes, except for VSGA significantly increased (+ 41%). The evaluation of antiretroviral exposure on pregnancy outcomes remains crucial to fully assess the benefice-risk balance, when prescribing ART in women of reproductive potential with HIV.

Review
INTRODUCTION
Diabetes mellitus (DM) is the leading cause of chronic kidney disease (CKD) and the optimal glycemic control is key to delay the progression of the disease and prevent major complications. Dipeptidyl peptidase-4 (DPP-4) inhibitors have emerged as a promising therapeutic option. However, the benefits and harms of the treatment have yet to be clarified for diabetic patients with CKD.
METHODS
Type 2 diabetic patients with moderate to severe CKD including end-stage renal disease were eligible and randomized controlled trials comparing DPP-4 inhibitors with no treatment or placebo or other antihyperglycemic agents were included. A systematic electronic search was conducted through the Medline Ovid, EMBASE, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov.
FINDINGS
Six placebo/open and 2 active controlled trials (1747 participants) were included. The adjusted mean difference of hemoglobin A between DPP-4 inhibitors and placebo ranged from -0.60% to -0.42%. The odds ratio of hypoglycemia, mortality and severe adverse effects due to all types of DPP-4 inhibitors were 1.35 (95% CI: 0.98-1.84), 0.88 (95% CI: 0.42-1.86) and 0.86 (95% CI: 0.65-1.15), respectively while that due to DPP-4 inhibitors with renal clearance were 1.40 (95% CI: 0.87 to 2.24), 0.85 (95% CI: 0.35 to 2.04) and 0.91 (95% CI: 0.63 to 1.32), respectively.
DISCUSSION
DPP-4 inhibitors demonstrated beneficial effects on the glycemic control for diabetic patients with CKD without causing any additional adverse effects. However, a definitive conclusion has yet to be drawn due to serious methodological problems and a small number of studies.

Review
DAA therapy is known to clear hepatitis C virus infection in patients with decompensated cirrhosis (DC). However, the safety and benefits of DAA in DC remain unclear, especially with the use of protease inhibitors (PI). Therefore, we evaluated the efficacy and clinical safety of DAA in DC patients and observed whether there was a discrepancy between PI-based and non-PI-based treatment. We searched Ovid-Medline, Ovid-EMBASE, Cochrane Library, and three local medical databases through October 2021 to identify relevant studies on the clinical safety and effectiveness of DAA in DC patients. The outcomes were sustained virologic response (SVR), overall mortality, the incidence rate of hepatocellular carcinoma (HCC), adverse events, improvement or deterioration of liver function, and delisting from liver transplantation (LT). Two independent reviewers extracted the data from each study using a standardized form. The pooled event rate in DC patients and relative effect (odds ratio (OR)) of PI-treated versus non-PI-based DAA in DC patients were calculated using a random-effects model. In patients with DC, the SVR rate was 86% (95% CI 83-88%), the development of HCC 7% (95% CI 5-9%), and mortality 6% (95% CI 4-8%). Improvement in liver function was observed in 51% (95% CI 44-58%) of patients, and 16% (95% CI 5-40%) were delisted from LT. PI-based treatment showed a similar rate of serious adverse events (23% vs. 18%), HCC occurrence (5% vs. 7%), and mortality (5% vs. 6%) to that of non-PI-based DAA treatment in DC patients. HCC occurrence and mortality rates were low in patients with DC following DAA treatment. PI-based treatment in DC patients was relatively safe when compared to non-PI-based treatment. Overall, DAA improved liver function, which may have allowed for delisting from LT.

Review
BACKGROUND
Carious affected dentine (CAD) represents a very common substrate in adhesive dentistry. Despite its ability to interact with adhesive systems, the intrinsic character of CAD leads to lower bonding compared with sound dentine, regardless of the adhesive systems used. This low bonding may be more susceptible to leakage and hydrolysis of the interface by matrix metalloproteinases (MMPs). This systematic review aimed to determine current knowledge of CAD bonding, together with bond strength and MMP inhibitors' ability to prevent hybrid layer instability.
METHODS
MEDLINE/Pubmed, Scopus and The Cochrane Library databases were electronically searched for articles published from 1 January 1960 to 31 August 2014. Two reviewers independently screened and included papers according to predefined selection criteria.
RESULTS
The electronic searches identified 320 studies. After title, abstract and full-text examinations, 139 articles met the inclusion criteria. Data highlighted that a poor resin saturation of the already demineralized collagen matrix in CAD is strictly related to nanoleakage in interdiffusion and is the basis of the progressive decrease in strength with hydrolysis by MMPs. The use of mild self-etching systems seems to be the more accredited method to establish bonding in CAD. Inhibitors of MMPs may ensure better performance of CAD bonding, allowing undisturbed remineralization of the affected matrix.
CONCLUSIONS
CAD bonding needs further understanding and improvement, particularly to enhance the strength and durability of the hybrid layer.

Meta-Analysis
BACKGROUND
Bloodstream infections (BSIs) produced by antibiotic-resistant bacteria (ARB) cause a substantial disease burden worldwide. However, most estimates come from high-income settings and thus are not globally representative. This study quantifies the excess mortality, length of hospital stay (LOS), intensive care unit (ICU) admission, and economic costs associated with ARB BSIs, compared to antibiotic-sensitive bacteria (ASB), among adult inpatients in low- and middle-income countries (LMICs).
METHODS AND FINDINGS
We conducted a systematic review by searching 4 medical databases (PubMed, SCIELO, Scopus, and WHO's Global Index Medicus; initial search n = 13,012 from their inception to August 1, 2022). We only included quantitative studies. Our final sample consisted of n = 109 articles, excluding studies from high-income countries, without our outcomes of interest, or without a clear source of bloodstream infection. Crude mortality, ICU admission, and LOS were meta-analysed using the inverse variance heterogeneity model for the general and subgroup analyses including bacterial Gram type, family, and resistance type. For economic costs, direct medical costs per bed-day were sourced from WHO-CHOICE. Mortality costs were estimated based on productivity loss from years of potential life lost due to premature mortality. All costs were in 2020 USD. We assessed studies' quality and risk of publication bias using the MASTER framework. Multivariable meta-regressions were employed for the mortality and ICU admission outcomes only. Most included studies showed a significant increase in crude mortality (odds ratio (OR) 1.58, 95% CI [1.35 to 1.80], p < 0.001), total LOS (standardised mean difference "SMD" 0.49, 95% CI [0.20 to 0.78], p < 0.001), and ICU admission (OR 1.96, 95% CI [1.56 to 2.47], p < 0.001) for ARB versus ASB BSIs. Studies analysing Enterobacteriaceae, Acinetobacter baumanii, and Staphylococcus aureus in upper-middle-income countries from the African and Western Pacific regions showed the highest excess mortality, LOS, and ICU admission for ARB versus ASB BSIs per patient. Multivariable meta-regressions indicated that patients with resistant Acinetobacter baumanii BSIs had higher mortality odds when comparing ARB versus ASB BSI patients (OR 1.67, 95% CI [1.18 to 2.36], p 0.004). Excess direct medical costs were estimated at $12,442 (95% CI [$6,693 to $18,191]) for ARB versus ASB BSI per patient, with an average cost of $41,103 (95% CI [$30,931 to $51,274]) due to premature mortality. Limitations included the poor quality of some of the reviewed studies regarding the high risk of selective sampling or failure to adequately account for relevant confounders.
CONCLUSIONS
We provide an overview of the impact ARB BSIs in limited resource settings derived from the existing literature. Drug resistance was associated with a substantial disease and economic burden in LMICs. Although, our results show wide heterogeneity between WHO regions, income groups, and pathogen-drug combinations. Overall, there is a paucity of BSI data from LMICs, which hinders implementation of country-specific policies and tracking of health progress.

Meta-Analysis Review
The real-world implementation of heart failure (HF) guidelines remains unclear. Our present systematic review and meta-analysis aimed to examine the rate of HF patients receiving guideline-directed treatment to identify the proportion of under-treatment patients and those who are treated with optimal doses, to evaluate the correlation of under-treatment patients' characteristics with the prescribed therapy, and finally, to evaluate the combined effect of the above on incidental mortality and rehospitalization. We conducted a systematic review of the literature indexed in Medline. We screened 1224 papers and excluded 1166 as they did not meet the inclusion criteria. Of the remaining 58 papers, which were evaluated by studying the full text, 11 papers that referred to 45866 patients were finally studied in this work. Angiotensin-Converting-Enzyme Inhibitor (ACEI) and Angiotensin II-Receptor Blocker (ARB) use was estimated to be 80.9% (95% CI: 73.9%, 86.4%), β-blockers' use was 78% (95% CI: 70.4%, 84.1%), Mineralocorticoid Receptor Antagonists' use was 47.4% (95% Cl 41.6%, 53.4%), and cardiac resynchronization therapy's use was 5.8% (95% Cl 3.4%, 9.6%). Meta-regression analysis showed that prescription of more than the half of target dose of ACEI/ARBs was found to be associated with reduced all-cause mortality (Z = -3.61, P = 0.0003), while the relationship with β-blockers was borderline (Z = -1.56, P = 0.11). A satisfactory adherence to the prescription of guideline-recommended treatment in patients with HF was observed. However, the under titration of the life-saving HF drugs need to be improved as only ultimate adherence to guideline-directed treatments may lead to the reduction of HF burden.

Meta-Analysis
: Dyslipidemia, particularly elevated low-density lipoprotein cholesterol (LDL-C), is a key risk factor for atherosclerotic cardiovascular disease (ASCVD), and lipid-lowering drugs are beneficial for the primary and secondary prevention of cardiovascular (CV) disease. While statins are clear first-line drugs, new drug developments such as proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have been shown to improve cardiovascular outcomes when added to statins. Evolocumab reduced the risk of cardiovascular events in patients with ASCVD when added to maximally tolerated statin therapy (± ezetimibe), and recent data from the ODYSSEY OUTCOMES trial indicate that alirocumab added to maximally tolerated statin therapy (± other lipid-lowering drugs) reduces the risk of cardiovascular events in patients with a recent acute coronary syndrome. In this article the authors review the available data on the effect of PCSK9 inhibitors on cardiovascular outcomes.: This article reviews the available data on the effect of PCSK9 inhibitors on CV outcomes. Relevant papers were identified from a search of PubMed/Medline and the Cochrane Central Register of Controlled Trials (CENTRAL).: The authors conclude that PCSK9 inhibitors provide substantial and durable reductions in LDL-C levels and improve cardiovascular outcomes.

Meta-Analysis Review
AIMS
The aim of this study was to continually evaluate the association between cardiovascular drug exposure and COVID-19 clinical outcomes (susceptibility to infection, disease severity, hospitalization, hospitalization length, and all-cause mortality) in patients at risk of/with confirmed COVID-19.
METHODS
Eligible publications were identified from more than 500 databases on 1 November 2020. One reviewer extracted data with 20% of the records independently extracted/evaluated by a second reviewer.
RESULTS
Of 52 735 screened records, 429 and 390 studies were included in the qualitative and quantitative syntheses, respectively. The most-reported drugs were angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) with ACEI/ARB exposure having borderline association with confirmed COVID-19 infection (OR 1.14, 95% CI 1.00-1.31). Among COVID-19 patients, unadjusted estimates showed that ACEI/ARB exposure was associated with hospitalization (OR 1.76, 95% CI 1.34-2.32), disease severity (OR 1.40, 95% CI 1.26-1.55) and all-cause mortality (OR 1.22, 95% CI 1.12-1.33) but not hospitalization length (mean difference -0.27, 95% CI -1.36-0.82 days). After adjustment, ACEI/ARB exposure was not associated with confirmed COVID-19 infection (OR 0.92, 95% CI 0.71-1.19), hospitalization (OR 0.93, 95% CI 0.70-1.24), disease severity (OR 1.05, 95% CI 0.81-1.38) or all-cause mortality (OR 0.84, 95% CI 0.70-1.00). Similarly, subgroup analyses involving only hypertensive patients revealed that ACEI/ARB exposure was not associated with confirmed COVID-19 infection (OR 0.93, 95% CI 0.79-1.09), hospitalization (OR 0.84, 95% CI 0.58-1.22), hospitalization length (mean difference -0.14, 95% CI -1.65-1.36 days), disease severity (OR 0.92, 95% CI 0.76-1.11) while it decreased the odds of dying (OR 0.76, 95% CI 0.65-0.88). A similar trend was observed for other cardiovascular drugs. However, the validity of these findings is limited by a high level of heterogeneity and serious risk of bias.
CONCLUSION
Cardiovascular drugs are not associated with poor COVID-19 outcomes in adjusted analyses. Patients should continue taking these drugs as prescribed.

Review
HIV-infected patients have a greater prevalence of dyslipidemia, earlier incidence and progression of atherosclerosis, and a nearly twofold increased risk for myocardial infarction compared with those not infected with HIV. Pre-existing cardiovascular risk factors, viral replication, and antiviral treatments all contribute to this accelerated and increased risk for cardiovascular disease in HIV-infected subjects. Given this risk and the proven benefit of statins reducing cardiovascular events across numerous patient groups, statin therapy might be particularly beneficial for patients with HIV. However, safety concerns and a dearth of quality trial data evaluating clinical outcomes in HIV-infected patients on simultaneous antiretroviral therapy (ART) and statin therapy have likely limited statin use in HIV-infected patients chronically taking ART. We performed a systematic review evaluating 18 clinical trials of statins in HIV-infected subjects receiving ART. Simvastatin is contraindicated in the setting of protease inhibitor use because of toxic drug-drug interactions when the 2 drugs are taken concomitantly. Meanwhile, atorvastatin appears to be relatively safe at submaximal doses if monitored. Pravastatin, rosuvastatin, and pitavastatin appear to have the most benign safety profiles among statins when co-administered with ART and may not require dose adjustment. In conclusion, clinicians should be mindful of the elevated risk for atherosclerotic cardiovascular disease in HIV-infected patients when assessing the need for lifestyle interventions and statin therapy.

Review
BACKGROUND
Type 2 diabetes mellitus (T2DM) is associated with an increased risk of stroke and an unfavourable outcome following stroke. Apart from pioglitazone, glucose-lowering modalities have not been shown to protect against stroke. Nevertheless, there is evidence from experimental studies of potential neuroprotective effects with dipeptidyl peptidase (DPP)-4 inhibitors, especially if treatment starts before stroke.
OBJECTIVE
To perform a meta-analysis of available evidence regarding the risk of stroke in individuals taking DPP-4 inhibitors.
METHODS
All available data from prospective randomized placebo-controlled trials involving DPP-4 inhibitors in T2DM patients published up to December 2015 were considered. The included trials reported data on the incidence of stroke with a recruitment rate of at least 100 diabetes patients and a follow-up of at least 12 weeks.
RESULTS
A total of 19 small randomized clinical trials (RCTs) evaluating the efficacy and safety of gliptins (n=9278), along with three multicentre prospective double-blind placebo-controlled RCTs assessing cardiovascular outcomes as the primary endpoint and involving 36,395 T2DM patients, were included in the analysis. Pooled analysis of the small RCTs showed a non-significant trend towards benefit with DPP-4 inhibitors against stroke [odds ratio (OR): 0.639, 95% confidence interval (CI): 0.336-1.212; P=0.170]. In contrast, in the analysis of RCTs reporting on cardiovascular safety, there was no difference in the risk of stroke with gliptin treatment compared with a placebo (OR: 0.996, 95% CI: 0.850-1.166; P=0.958).
CONCLUSION
The promising data from experimental studies regarding cardioprotective gliptin-associated effects against stroke were not supported by available data from trials specifically looking at cardiovascular safety.
