Background Liver abscesses differ in their aetiology, location, and number. Image‐guided percutaneous drainage techniques are the currently used management for liver abscesses. We conducted our study to compare the clinical safety and efficacy of percutaneous needle aspiration (PNA) to percutaneous catheter drainage (PCD). Methods A systematic review of major reference databases was undertaken in February 2022 for randomized controlled trials (RCTs) that compare PNA to PCD in treating liver abscess patients. The quality of the included trials was assessed using the Cochrane tool. Statistical meta‐analysis was conducted using RevMan and open meta‐analyst software. Results Fifteen RCTs were included in this review, with 1676 patients enrolled. The overall quality of the included trials was moderate, with most domains of unclear risk. PCD was superior to PNA in the success rate (RR = 1.23; 95% CI [1.12, 1.36], P < 0.00001), time for achieving 50% reduction of cavity size (MD = −2.32; 95% CI [−3.07, −1.57], P < 0.00001), and time for clinical improvement (MD = −1.92; 95% CI [−2.55, −1.28], P < 0.00001). The two modalities did not differ in the days of hospital stay, duration of IV antibiotics, and time needed for total or subtotal reduction of cavity size (P = 0.36, P = 0.06 and P = 0.40, respectively). High heterogeneity levels were detected. Regarding major complications, the two modalities were equally safe (P = 0.39). Conclusion PCD has a higher success rate and results in a faster 50% reduction in the abscess cavity size and clinical improvement. The two modalities are equally safe.

The current paper explores the effect of private market characteristics on the access of small and medium enterprises (SMEs) to public markets in some sectors. Using survey data of small and medium enterprises in the pharmaceutical sector in Egypt, we confirmed this effect. We found that regulations of drugs pricing and registration in the private market constrained the capacity of those firms to compete in the public markets. However, some other factors play it the other way. The policy implications of these findings indicate that governments need to account for private markets characteristics when designing support packages for smaller enterprises in public procurement markets.

We investigate the cyclicality of fiscal policy in Egypt during the period of 1976–2019 with a focus on how budgetary and political institutions affect fiscal performance during economic cycles. We define new variables for budgetary and political institutions and incorporate them in a vector error correction model (VECM) and impulse response functions (IRFs) analysis. While current and capital spending are proven to behave procyclically, revenues respond countercyclically during business cycles. Poor political and budgetary institutions have a negative impact on the primary deficit in a way that led to procyclical behaviour in fiscal policy in the long run. We recommend reinforcing the Golden Rule and changing the nature of the electoral system to a party-based to strengthen the role of parliament in keeping the government accountable
