Financial Development and Economic Growth: The Case of Pakistan

In this study, the relationship between financial depth and economic growth is examined in an Autoregressive Distributed Lag (ARDL) framework for Pakistan utilising annual data for the period 1971- 2004. The main empirical findings suggest that both in the long and the short run, financial depth exerted a positive effect on economic growth. The findings also suggest that in the long run, real interest rate had a significant and positive effect on economic growth. However, the short-run response of the real interest

Financial Development and Economic Growth: The Case of Pakistan

The pioneering contributions of Goldsmith (1969), Mckinnon (1973) and Shaw (1973) regarding the relationship between financial development and economic growth has remained an important issue of debate in developing economies. The theoretical argument for linking financial development to growth is that a well-developed financial system performs several critical functions to enhance the efficiency of intermediation by reducing information, transaction, and monitoring costs. A modern financial system promotes investment by identifying and funding good business opportunities, mobilises savings, monitors the performance of managers, enables the trading, hedging, and diversification of risk, and facilitates the exchange of goods and services. These functions result in a more efficient allocation of resources, in a more rapid accumulation of physical and human capital, and in faster technological progress, which in turn feed economic growth [Creane, et al. (2004)]

Current status of Helicobacter pylori association with haematological and cardiovascular diseases: A mini review

Helicobacter pylori infection is considered the most commonly prevalent gastrointestinal pathogen where it manages to survive despite the hostile environment of human stomach, leading to various gastric diseases including gastric cancer. Due to the chronic inflammatory state induced by H. pylori and its interaction with host immune system have diverted researchers to investigate its correlation with systemic diseases outside of the gastrointestinal tract. This literature review was done to explore the association of H. pylori infection with haematological and cardiovascular diseases. We used medical subject heading (MeSH) terms Helicobacter pylori with inflammation, haematological diseases, coronary heart diseases or vascular diseases to search PubMed database. All relevant studies identified from 2005 to 2015 were included. As many of the studies are small-scale or showed weak association, further studies are needed to address the role of H. pylori in pathogenesis of haematological and cardiovascular diseases

Self-reported attitudes and behaviours of medical students in Pakistan regarding academic misconduct: A cross-sectional study

Background: Honesty and integrity are key attributes of an ethically competent physician. However, academic misconduct, which includes but is not limited to plagiarism, cheating, and falsifying documentation, is common in medical colleges across the world. The purpose of this study is to describe differences in the self-reported attitudes and behaviours of medical students regarding academic misconduct depending on gender, year of study and type of medical institution in Pakistan.Methods: A cross sectional study was conducted with medical students from one private and one public sector medical college. A pre-coded questionnaire about attitudes and behaviours regarding plagiarism, lying, cheating and falsifying documentation was completed anonymously by the students.Results: A total of 465 medical students filled the questionnaire. 53% of private medical college students reported that they recognize copying an assignment verbatim and listing sources as references as wrong compared to 35% of public medical college students. 26% of private medical college students self-report this behaviour as compared to 42% of public medical college students. 22% of private versus 15% of public medical college students and 21% of students in clinical years compared to 17% in basic science years admit to submitting a fake medical certificate to justify an absence. 87% of students at a private medical college believe that cheating in an examination is wrong as compared to 66% of public medical college students and 24% self-report this behaviour in the former group as compared to 41% in the latter. 63% of clinical year students identify cheating as wrong compared to 89% of their junior colleagues. 71% of male versus 84% of female respondents believe that cheating is wrong and 42% of males compared to 23% of females admit to cheating.Conclusions: There are significant differences in medical students\u27 attitudes and behaviours towards plagiarism, lying, cheating and stealing by gender, seniority status and type of institution. The ability to identify acts of academic misconduct does not deter students from engaging in the behaviour themselves, as evidenced by self-reporting

Influence of Tributyltin (TBT) on Level of Free Testosterone in Two Species of Neogastropods Found Along the Coast of Pakistan.

Organotin compounds are used in antifouling paints and wood preservatives to prevent fouling of marine organisms on ships and other marine structures. The leaching of these compounds has caused imposex (pseudohermaphroditism) globally in females of over 170 species of prosobranch gastropods inhabiting areas close to marinas and harbours. The investigations of imposex induction pathway indicate that tributyltin (TBT) and triphenyltin (TPhT) produce this abnormality via endocrine dysfunction, interfering with the regulation of testosterone. The two gastropod species Thais bufo and T. rudolphi were analyzed from Manora Rocky Ledge, Clifton and Gadani Ship Breaking Yard. At Gadani Ship Breaking Yard the incidence of imposex was 100% while at the other two sites no imposex female was encountered. The testosterone levels were analyzed by using radio immunoassay (RIA). Higher levels of testosterone were recorded in imposex females than males at Gadani Ship Breaking Yard. However, from Clifton and Manora Rocky Ledge, elevated concentrations of testosterones were noted in males as compared to females. The relatively higher level of testosterone in imposex females from Gadani Ship Breaking Yard area indicates that TBT is an active biocidal agent released into marine environment during ship recycling process and is responsible for development of imposex and leading to elevated level of free testosterone in targeted species

Potential of Functionalized Magnetite (Fe3O4) in Decontamination of Pathogenic Bacteria from Milk

Magnetite (Fe3O4) is getting popular due to its super-paramagnetic properties, high biocompatibility and lack of toxicity to humans. Magnetite (Fe3O4) nanoparticles have high surface energy thus these nanoparticles aggregate quickly. This aggregation strongly affects the efficiency of these nanoparticles. So these magnetite nanoparticles are coated with organic or inorganic substance to prevent aggregation. These coatings not only stabilize magnetic nanoparticles but can also be used for further functionalization. The aim of this study was to evaluate the efficiency of functionalized magnetite to remove pathogenic bacteria (E.coli and B.cereus) from milk considering binding capability of magnetite with bacterial cell wall. Magnetite (Fe3O4) was prepared by co-precipitation method and subsequently functionalized with oleic acid (OA) and ethylene diamine (EDA). In present study role of magnetite (Fe3O4) and functionalized magnetite (EDA-Fe3O4, OA-Fe3O4) in removal of pathogenic bacteria (E.coli and B.cereus) from milk was investigated. The morphology of functionalized magnetite was determined by Scanning Electron microscopy (SEM). Their removal efficiency was studied based on time (10, 20 and 30 minutes). Concentration of uncoated magnetite (Fe3O4) and coated magnetite (EDA-Fe3O4, OA-Fe3O4) was fixed at 4mg/50mL. Magnetite was successfully synthesized in range of +/- 3nm. Highest capturing efficiency (74.45%) of oleic acid magnetite (OA-Fe3O4) was observed for Bacillus cereus at 30 minutes. However for Escherichia coli, both ethylene-diamine magnetite (EDA-Fe3O4) and oleic acid magnetite (OA-Fe3O4) showed maximum capturing efficiency (61.65% and 63.91% respectively). It was concluded from the study that magnetite coated with oleic acid and ethylenediamine removed pathogenic bacteria from milk efficiently. However, more research is required to study the effect of these magnetic nanoparticles on nutritional composition of milk.Peer reviewe

Assessment of total phenolic and flavonoid contents of selected fruits and vegetables

686-693This work was conceptualized with the goal to investigate different fruits and vegetables for their comparative investigation of total phenolic and total flavonoid contents. The total phenolic content of 9 fruits and 12 vegetables used in the current study was determined by Folin-Ciocalteau assay. In addition, total flavonoid content was identified through catechin and aluminum colorimetric analysis. The ratio among the phenolic and flavonoid contents of fruits and vegetables extracts were also analyzed. Our results showed that methanolic extract of Citrullus lanatus had higher contents of phenolics and flavonoids (215±1.24 mg GAE/100 g and 73±0.81 mg CE/100 g) than other fruits. Moreover, maturity process of fruits from unripened to fully ripened stage showed significant increase in the total phenolic and flavonoid contents. Fruits under study had shown flavonoids/phenolics ratio of 0.32, which indicates that these fruits contained about 32% of flavonoid contents. Among vegetables, the greatest value of phenolic contents was observed in Capsicum annuum (213±1.24 mg GAE/100 g), and total flavonoid content in Raphanus sativus (45±1.24 mg CE/100 g). Vegetables showed lower ratios of flavonoids/phenolics (0.11-0.2) indicating lesser total flavonoid content (11-20%) as compared with fruits. The obtained results indicate that fruits and vegetables could be attributed to a potential source of natural phenolics and flavonoids in the pharmaceutical and food industry. Moreover, the antioxidant activities of these selected fruits and vegetables should also be determined in order to explore their beneficial effects against the prevention and management of disorders caused by oxidative stress

Antimicrobial Usage and Resistance in Makkah Region Hospitals: A Regional Point Prevalence Survey of Public Hospitals

(1) Background: Inappropriate use of antimicrobials and subsequently rise of antimicrobial resistance (AMR) remains a major public health priority. Over-prescribing of broad-spectrum antibiotics is one of the main contributing factors for the emergence of AMR. We sought to describe antimicrobial prescribing trends among patients in public hospitals in Makkah hospitals. (2) Method: We undertook a point prevalence survey (PPS) in six hospitals in Makkah, Saudi Arabia, from January 2019 to July 2019. The survey included all the inpatients receiving antimicrobials on the day of PPS. Data was collected using the Global point prevalence survey (PPS) tool developed by the University of Antwerp, Belgium. (3) Results: Of 710 hospitalized patients, 447 patients (61.9%) were treated with one or more antimicrobials during the study period. The average bed occupancy among six hospitals was 74.4%. The majority of patients received antimicrobials parenterally (90.3%). Of the total prescribed antimicrobials, 415 (53.7%) antimicrobials were used in medical departments, 183 (23.7%) in surgical departments, and 175 (22.6%) in ICUs. Pneumonia (17.3%), skin and soft tissue infections (10.9%), and sepsis (6.6.%) were three common clinical indications. Ceftriaxones were the most commonly used antibiotics that were prescribed in 116 (15%) of patients, followed by piperacillin, with an enzyme inhibitor in 84 (10.9%). (4) Conclusion: There was a high prevalence of antibiotic use in the hospitals of Makkah, which could be a potential risk factor for the incidence of resistant strains, particularly MRSA infection. Public health decision-makers should take these findings into consideration to update national policies for antibiotic use in order to reduce the risks of further increases of AMR

Early Intervention in Psychosis and Management of First Episode Psychosis in Low- and Lower-Middle-Income Countries: A Systematic Review

Background and Hypothesis People with first-episode psychosis (FEP) in low- and lower-middle-income countries (LMIC) experience delays in receiving treatment, resulting in poorer outcomes and higher mortality. There is robust evidence for effective and cost-effective early intervention in psychosis (EIP) services for FEP, but the evidence for EIP in LMIC has not been reviewed. We aim to review the evidence on early intervention for the management of FEP in LMIC. Study Design We searched 4 electronic databases (Medline, Embase, PsycINFO, and CINAHL) to identify studies describing EIP services and interventions to treat FEP in LMIC published from 1980 onward. The bibliography of relevant articles was hand-searched. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Study Results The search strategy produced 5074 records; we included 18 studies with 2294 participants from 6 LMIC countries. Thirteen studies (1553 participants) described different approaches for EIP. Pharmacological intervention studies (n = 4; 433 participants) found a high prevalence of metabolic syndrome among FEP receiving antipsychotics (P ≤ .005). One study found a better quality of life in patients using injectables compared to oral antipsychotics (P = .023). Among the non-pharmacological interventions (n = 3; 308 participants), SMS reminders improved treatment engagement (OR = 1.80, CI = 1.02–3.19). The methodological quality of studies evidence was relatively low. Conclusions The limited evidence showed that EIP can be provided in LMIC with adaptations for cultural factors and limited resources. Adaptations included collaboration with traditional healers, involving nonspecialist healthcare professionals, using mobile technology, considering the optimum use of long-acting antipsychotics, and monitoring antipsychotic side effects
