    Government Spending And Economic Growth Nexus In Sub-Saharan Africa: An Econometric Analysis

    Proponents of larger governments argue that government programmes provide essential public goods like education and infrastructure, which, in turn, stimulate the economy. On the other hand, individuals who advocate for more limited government assert that an increase in public spending will be detrimental to economic expansion due to the fact that many functions of government are inefficient and not in the public interest. Secondary data from World development indicator variables spanning from 1985 to 2021 were analysed. The dependent variable for the study was GDP per capita and the independent variables were institutional quality, government expenditure, capital stock and trade openness. The model used for the study are Pearson correlation, Pesaran's , Friedman's and Frees' cross sectional dependency test, IPS and CIPS unit root test, Pooled Mean Group and Dynamic Fixed Effect regression to test for the long-run cointegration and short-run relationship in 32 African countries. The results of the study suggest that there exists a long-run and short-run relationship between government expenditure and economic growth. Additionally, the study emphasises the importance of institutional quality as a significant determinant of this relationship. Therefore, it is recommended that all accessible government funds be allocated towards the objective of establishing durable and self-sufficient infrastructure

    Statin therapy in critical illness : an international survey of intensive care physicians' opinions, attitudes and practice

    Background Pleotropic effects of statins on inflammation are hypothesised to attenuate the severity of and possibly prevent the occurrence of the host inflammatory response to pathogen and infection-related acute organ failure. We conducted an international survey of intensive care physicians in Australia, New Zealand (ANZ) and United Kingdom (UK). The aims of the survey were to assess the current prescribing practice patterns, attitudes towards prescribing statin therapy in critically ill patients and opinions on the need for an interventional trial of statin therapy in critically ill patients. Methods Survey questions were developed through an iterative process. An expert group reviewed the resulting 26 items for face and content validity and clarity. The questions were further refined following pilot testing by ICU physicians from Australia, Canada and the UK. We used the online Smart SurveyTM software to administer the survey. Results Of 239 respondents (62 from ANZ and 177 from UK) 58% worked in teaching hospitals; most (78.2%) practised in ‘closed’ units with a mixed medical and surgical case mix (71.0%). The most frequently prescribed statins were simvastatin (77.6%) in the UK and atorvastatin (66.1%) in ANZ. The main reasons cited to explain the choice of statin were preadmission prescription and pharmacy availability. Most respondents reported never starting statins to prevent (65.3%) or treat (89.1%) organ dysfunction. Only a minority (10%) disagreed with a statement that the risks of major side effects of statins when prescribed in critically ill patients were low. The majority (84.5%) of respondents strongly agreed that a clinical trial of statins for prevention is needed. More than half (56.5%) favoured rates of organ failure as the primary outcome for such a trial, while a minority (40.6%) favoured mortality. Conclusions Despite differences in type of statins prescribed, critical care physicians in the UK and ANZ reported similar prescription practices. Respondents from both communities agreed that a trial is needed to test whether statins can prevent the onset of new organ failure in patients with sepsis

    Fresh University Students and Phone Use Preferences: The Perception of a Public University in Ghana

    The current study was a case study in one of the public universities in Ghana to ascertain phone acquisition and use tendencies of first year university students in their first semester of university education. A sample size of 300 was used for the study. The findings indicated that all the 300 (100%) students had phones whilst 223 (74.3%) of them had smartphones with internet functionality. It was found out that there was a significant difference between first year university students’ time spent on phones, based on age. Again, there was a significant negative correlation between first year university students’ time spent on phones based on their age. Further, the study revealed that first year university students were more likely to spend one semester (four months) on their phones in a four-year programme. The implications for practice have been discussed. Keywords: cell phones use, classroom, phone acquisition, time, first year students

    Modeling the Effects of Drug Binding on the Dynamic Instability of Microtubules

    We propose a stochastic model that accounts for the growth, catastrophe and rescue processes of steady state microtubules assembled from MAP-free tubulin. Both experimentally and theoretically we study the perturbation of microtubule dynamic instability by S-methyl-D-DM1, a synthetic derivative of the microtubule-targeted agent maytansine and a potential anticancer agent. We find that to be an effective suppressor of microtubule dynamics a drug must primarily suppress the loss of GDP tubulin from the microtubule tip.Comment: 17 pages, 11 figures, to appear in Phys.

    Is IL-1β Further Evidence for the Role of Propionibacterium acnes in Degenerative Disc Disease? Lessons From the Study of the Inflammatory Skin Condition Acne Vulgaris

    Get PDF
    The pathogenesis of degenerative disc disease is a complex and multifactorial process in which genetics, mechanical trauma, altered loading and nutrition present significant etiological factors. Infection of the intervertebral disc with the anaerobic bacterium Propionibacterium acnes is now also emerging as a potentially new etiological factor. This human commensal bacterium is well known for its long association with the inflammatory skin condition acne vulgaris. A key component of inflammatory responses to P. acnes in acne appears to be interleukin (IL)-1β. Similarly, in degenerative disc disease (DDD) there is compelling evidence for the fundamental roles of IL-1β in its pathology. We therefore propose that P. acnes involvement in DDD is biologically very plausible, and that IL-1β is the key inflammatory mechanism driving the host response to P. acnes infection. Since there is a solid theoretical basis for this phenomenon, we further propose that the relationship between P. acnes infection and DDD is causal

    Blue Skies research is essential for ending the Tuberculosis pandemic and advancing a personalized medicine approach for holistic management of Respiratory Tract infections

    Objectives: Investments into ‘blue skies’ fundamental TB research in low- and middle-income countries (LMICs) have not been forthcoming. We highlight why blue skies research will be essential for achieving global TB control and eradicating TB. // Methods: We review the historical background to early TB discovery research and give examples of where investments into basic science and fundamental ‘blue skies research’ are delivering novel data and approaches to advance diagnosis, management and holistic care for patients with active and latent TB infection. // Findings: The COVID-19 pandemic has shown that making available adequate funding for priority investments into ‘Blue skies research’ to delineate scientific understanding of a new infectious diseases threat to global health security can lead to rapid development and rollout of new diagnostic platforms, treatments, and vaccines. Several advances in new TB diagnostics, new treatments and vaccine development are underpinned by basic science research. // Conclusions: Basic science research focused can pave the way for a personalized medicine approach for management of TB and other Respiratory Tract Infections and preventing long-term functional disability. Transfer of skills and resources by wealthier nations is required to empower researchers in LMICs countries to engage in and lead basic science ‘blue skies research
