Abstract
BACKGROUND Despite the potential of corticosteroids in treating community-acquired pneumonia (CAP), conflicting evidence exists regarding their effect on mortality. To address this gap and provide new insights, we conducted a pre-specified subgroup meta-analysis of corticosteroid use in CAP patients, focusing on the ICU versus non-ICU subsets. METHODS We searched PubMed, Cochrane Central Register of Controlled Trials and SCOPUS from inception to May 2023 for randomized controlled trials (RCTs). The primary outcomes of interest were mortality, need for mechanical ventilation, need for ICU admission, and treatment failure. Secondary outcomes analysed were the need for hospital readmission, length of hospital stay, length of ICU stay, gastrointestinal (GI) bleeding, secondary infections, and hyperglycaemic events. The results were analysed through the random-effects model. A p-value < 0.05 was considered significant. RESULTS Eighteen randomized controlled trials (n = 4472) analyzing patients withCAP were included. Our results suggest that corticosteroids significantly reduced the incidence of mortality (RR: 0.66; 95 % CI: 0.54, 0.81; P = <0.0001) and need for mechanical ventilation (RR: 0.57; 95 % CI: 0.44, 0.73; P = <0.00001). It was also observed that corticosteroids significantly decrease the lengths of ICU (MD: -1.67; 95 % CI: -2.97, -0.37; P = 0.01) and hospital stay (MD: -1.94; 95 % CI: -2.89, -0.98; P = 0.0001), while increasing the number of hyperglycemic events (RR: 1.68; 95 % CI: 1.32, 2.12; P = <0.0001) and hospital readmissions (RR: 1.19; 95 % CI: 1.04, 1.37; P = 0.01). CONCLUSIONS The results of this meta-analysis demonstrate that corticosteroids yield improved outcomes in CAP patients with regard to reduced mortality and the need for mechanical ventilation. It highlights the need for further large-scale RCTs with the proposed, specific stratifications.

Abstract
AIM Statin therapy is considered the gold standard for treating hypercholesterolemia. This updated meta-analysis aims to compare the efficacy and safety of a low/moderate-intensity statin in combination with ezetimibe compared with high-intensity statin monotherapy in patients with atherosclerotic cardiovascular disease (ASCVD). METHODS A systematic search of two databases (PubMed and Cochrane CENTRAL) was conducted from inception to January 2023 and a total of 21 randomized clinical trials (RCTs) were identified and included in the analysis. Data were pooled using Hedges's g and a Mantel-Haenszel random-effects model to derive standard mean differences (SMDs) and 95% confidence intervals (Cis). The primary outcome studied was the effect of these treatments on lipid parameters and safety events. RESULTS The results revealed that combination therapy was more effective in reducing low-density lipoprotein cholesterol (LDL-C) levels (SMD= - 0.41; CI - 0.63 to - 0.19; P = 0.0002). There was no significant change in the levels of high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), triglyceride (TG), high-sensitivity C-reactive protein (hs-CRP), Apo A1, or Apo B. The safety of these treatments was assessed by the following markers alanine aminotransferase (ALT), aspartate aminotransferase (AST), and creatine phosphokinase (CK), and a significant difference was only observed in CK (SMD: - 0.81; CI - 1.52 to - 0.10; P = 0.02). CONCLUSION This meta-analysis demonstrated that the use of low/moderate-intensity statin combination therapy significantly reduced LDL-C levels compared with high-intensity statin monotherapy, making it preferable for patients with related risks. However, further trials are encouraged to evaluate potential adverse effects associated with combined therapy.

Abstract
INTRODUCTION This meta-analysis aimed to evaluate the safety and efficacy of direct endovascular therapy (EVT) and bridging therapy (EVT with preceding intravenous thrombolysis i.e. IVT), in acute anterior circulation, large vessel occlusion stroke. EVIDENCE ACQUISITION Following the PRISMA guidelines, a systematic literature review of the English language literature was conducted using PubMed, Cochrane CENTRAL, SCOPUS and ClinicalTrials.gov. Outcomes of interest were measured by the modified Rankin Scale (mRS), and included: no disability (mRS0), no significant disability despite some symptoms (mRS1), slight disability (mRS2), moderate disability (mRS3), moderately severe disability (mRS4), severe disability (mRS5), mortality (mRS6). Additionally, we inspected patients having excellent outcome, functional independence outcome, and poor outcome, along with successful reperfusion and intracranial hemorrhage. We calculated pooled risk ratios (RRs) and their corresponding 95% confidence intervals (CI). EVIDENCE SYNTHESIS A total of seven RCTs involving 2,392 patients were finally included. The chances of achieving successful reperfusion were significantly more with IVT+EVT as compared to EVT alone (RR: 0.97; 95% CI: 0.94, 1.00; P=0.03) (I2=0%). There was no significant difference in the number of patients having outcomes ranging from mRS0 to mRS6, excellent outcome, functional independence, poor outcome or incidence of intracranial hemorrhage, who underwent either EVT alone or IVT+EVT. CONCLUSIONS Additional trials are needed to determine if the absence of significant differences is due to insufficient sample size or if the combination therapy is truly not beneficial.

Abstract
Mammalian cells have been microencapsulated within both natural and synthetic polymers for over half a century. Specifically, in the last 36 years microencapsulated cells have been used therapeutically to deliver a wide range of drugs, cytokines, growth factors, and hormones while enjoying the immunoisolation provided by the encapsulating material. In addition to preventing immune attack, microencapsulation prevents migration of entrapped cells. Cells can be microencapsulated in a variety of geometries, the most common being solid microspheres and hollow microcapsules. The micrometer scale permits delivery by injection and is within diffusion limits that allow the cells to provide the necessary factors that are missing at a target site, while also permitting the exchange of nutrients and waste products. The majority of cell microencapsulation is performed with alginate/poly-L-lysine microspheres. Since alginate itself can be immunogenic, for cell-based therapy applications various groups are investigating synthetic polymers to microencapsulate cells. We describe a protocol for the formation of microspheres and microcapsules using the synthetic polymer poly(ethylene glycol) diacrylate (PEGDA).

Abstract
Holy basil, Ocimum sanctum (L.) is time-honored for its medicinal properties; however its antimicrobial characteristics are used only in 'Ayurvedic medicines'. Attention has been drawn to antifungal activity and a possible synergistic antifungal effect of Ocimum sanctum essential oil (OSEO) and established azole antimycotics-fluconazole and ketoconazole. To put forward this approach, antifungal activity has been assessed in seventy four fluconazole-sensitive and sixteen fluconazole-resistant Candida isolates. Hemolytic activity on human erythrocytes was also studied to rule out the possibility of allied additional cytotoxicity. The observed selectively fungicidal characteristics signify a promising candidature of O. sanctum essential oil as an antifungal agent in combinational treatments for candidosis.

Abstract
BACKGROUND Recruitment and retention of dentists in the public sector and rural areas in Victoria has become increasingly difficult in recent years. There are little available data on the factors that influence the sector and location of practice of new dental graduates. The objective of this study was to investigate the factors considered by new graduates in determining the location and sector of employment after graduation, and influencing any early changes in career path. METHODS Questionnaires were sent to dentists who Mgraduated from The Univrersity of Melbourne from graduated from The University of Melbourne from 2000-2003 who were currently practising in Victoria. There were 154 subjects to whom questionnaires were sent and 109 useable questionnaires were returned, a response rate of 74 per cent. RESULTS Upon graduation, 53 per cent of the new graduates chose to work in the private sector only, compared to 15 per cent in public sector only and 33 per cent in both. At present, 71 per cent work in the private sector only, 17 per cent in the public sector only and 12 per cent in both. The most important factors for choosing to work in the private sector were receiving broad range of clinical experience, opportunities to familiarize with practice management and providing a continuity of care. The principal factors for practising in the public sector were clinical mentoring and advice, consolidating clinical skills and work environment. Initially, 48 per cent of the sample chose to work in metropolitan areas only, 39 per cent in rural areas only and 13 per cent in both. Factors that influenced the decision to work in rural areas were the broad range of clinical experience and remuneration, while the main factors for choosing to work in metropolitan areas were lifestyle and proximity to family and friends. CONCLUSIONS This study found that a large proportion of new dental graduates initially chose to work in the public sector and rural areas on graduation primarily as a means of consolidating their clinical skills. However, retention of dentists in both these areas appears to be a problem, with less than 10 per cent of 2000-2001 graduates still than 10 per cent of 2000-2001 graduates still working in the public sector and only 20 per cent of 2000-2001 graduates still working in rural areas.

Abstract
Thromboembolic disease during pregnancy has traditionally been treated with heparin. If heparin cannot be used, then treatment options remain limited. Despite the recent availability of new anticoagulation agents, data relating to their use during pregnancy is lacking. Hirudin, a relatively new anti-thrombotic agent, through animal models has been shown to have a very low transplacental transfer, thus making it a candidate drug to be used during pregnancy in case of heparin allergy. This report describes a case of heparin allergy in a pregnant patient with recurrent DVT that was successfully managed with hirudin and coumadin.

Abstract
Thrombotic thrombocytopenic purpura is a rare complication of ticlopidine treatment. This syndrome has been reported to occur typically within the first few weeks after the initiation of therapy. The authors describe a case of a 72-year-old woman in whom thrombotic thrombocytopenic purpura developed just 2 days after starting ticlopidine therapy for a new-onset ischemic stroke. The patient responded successfully to plasmapheresis. The authors are reporting this case to emphasize the unpredictable nature of the association between the drug and the disease, which necessitates careful hematologic monitoring.
