Knowledge, attitude and practice regarding immunization among family practice patients
Objective: To determine the knowledge, attitude and practices about immunization among family practice patients. Design: A questionnaire based survey. Patients and Method: A questionnaire was developed in line with the study objectives. It was administered to patients visiting family physicians, after they were administered, informed consent and assurance with regards to confidentiality was provided. Epi-info and SPSS software was used for data management. Results: A total of 97 patients were surveyed. The majority were men (59.8%) with a mean age of 29.69 years. Majority was unmarried (51.5%), with graduate and post-graduate education (73%), and in government and private service (48%). Vaccination was believed to prevent disease by 94%. Majority was informed about immunization by doctors and parents (94%). Media provided information about immunization to 62% of the patients. A 58% would recommend vaccination to others. Source about harmful effects of immunization was provided by friends and parents (80%). Hurdles against immunization were lack of education and lack of funds according to 43 (45%) and 29 (30%) respondents respectively. Education of population and mothers were ways to promote immunization according to 23 (24%) and 19 (20%) respondents respectively. Immunization exists against Hepatitis C and Malaria according to 35 (36%) and 10 (10%) respondents respectively. Immunization were received against polio, measles and hepatitis B by 86 (89%), 51 (53%) and 26 (27%) respondents respectively. Conclusion: The study results have identified a strong need for education program for the masses about immunization, since major deficiencies have been identified. Further studies are strongly recommended along with debate on this important public health issue
Combined experimental and theoretical study of poly(aniline-co-pyrrole) oligomer
Quantum mechanical calculations are performed to establish the structure of an oligomer of aniline and pyrrole [Poly(Ani-co-Py)], through comparison of experimental and theoretically calculated properties, including conductivity. The copolymer was synthesized through chemical oxidative polymerization and then confirmed from the experimental IR, UV-vis, mass spectra, elemental, XRD, TGA, and SEM analysis. Quantum mechanical calculations are performed at Density Functional Theory (DFT) and Time dependent DFT (TD-DFT) methods for the electronic and spectroscopic properties of the oligomer. A very nice correlation is found between the theory and experiment which consequences the structure of Poly(Ani-co-Py). Poly(Ani-co-Py) is not explored like other conducting polymers; however, by tuning this molecular structure, the electro-active nature of this material can be enhanced adequately
Demographic and Clinical Features of Dengue Fever in Pakistan from 2003–2007: A Retrospective Cross-Sectional Study
Background: Demographic features of dengue fever have changed tremendously in Pakistan over the past two decades. Small scale studies from all over the country have reported different aspects of individual outbreaks during this time. However, there is scarcity of data looking at the overall trend of dengue virus infection in the country. In this study, we examined annual trends, seasonality, and clinical features of dengue fever in the Pakistani population.Methods: Demographic information and dengue IgM status of all patients tested for dengue IgM antibody at Aga Khan University Hospital from January 2003 to December 2007 were analyzed to look for trends of IgM-positive cases in Pakistan. In addition, clinical and biochemical parameters were abstracted retrospectively from medical records of all patients hospitalized with IgM-proven dengue fever between January 2006 and December 2007. These patients were categorized into dengue fever and dengue hemorrhagic fever according to the WHO severity grading scale.Results: Out of a total of 15040 patients (63.2% male and 36.8% female), 3952 (26.3%) tested positive for dengue IgM antibody. 209 IgM proven dengue patients were hospitalized during the study period. During 2003, IgM positive cases were seen only during the months of July-December. In contrast, such cases were detected throughout the year from the 2004– 2007. The median age of IgM positive patients decreased every year from 32.0 years in 2003 to 24.0 years in 2007 (p,0.001). Among hospitalized patients, nausea was the most common presenting feature found in 124/209 (59.3%) patients. Children presented with a higher median body temperature than adults (p = 0.010). In addition, neutropenia was seen more commonly in children while raised serum ALT levels were seen more commonly in adults (both p = 0.006). While a low total white cell count was more common in patients with dengue fever as compared to Dengue Hemorrhagic Fever (p = 0.020), neutropenia (p = 0.019), monocytosis (p = 0.001) and raised serum ALT level (p = 0.005) were observed more commonly in the latter group.Conclusions: Dengue virus is now endemic in Pakistan, circulating throughout the year with a peak incidence in the post monsoon period. Median age of dengue patients has decreased and younger patients may be more susceptible. Total and differential leukocyte counts may help identify patients at risk of hemorrhage
Role of financial literacy in achieving financial inclusion: A review, synthesis and research agenda
Financial inclusion is an international policy agenda and can be achieved through financially literate people, who can make informed financial decisions and improve individuals' well-being. The area of Financial Literacy and Financial Inclusion is fairly highlighted in the literature; however, the collective importance of how these two areas are researched together needs scholarly attention. This paper carries out a mapping, scientometric and content analysis by compiling studies at the intersection of financial literacy and financial inclusion from a sample of 10,091 studies spread over the last 45Â years and conducted on a sample of more than 850,000 individuals worldwide. We find that the number of studies increases; by fields, Finance and Economics dominate the literature; by countries, most studies come from developed countries, in particular the US; by authors, citations are skewed and by measures; studies are moving from non-functional measures to functional measures. Overall, the interest in financial literacy in bringing financial inclusion and its multifaceted role is elaborated using conceptual framework following which future research is positioned. Thus, aiding policymakers, regulators, and academicians to know the distinction of Financial literacy in Financial inclusion and to identify the potential research areas
Impact of working status on their lives: a survey of working women at a teaching hospital in Karachi, Pakistan
Objective: To study the impact of working status on the lives of working women.Methodology: A questionnaire based cross sectional survey was conducted at the Family Practice Center, Aga Khan University Hospital, Karachi, Pakistan, from July to December 2006. The Questionnaire included data on the demographic profile of the patient and questions in line with study objectives. Ethical requirement including the administration of written informed consent and the provision of confidentiality were ensured. SPSS computer software was used for data analysis. Results: Two hundred working women were interviewed. The mean age was 29.05 years. A majority was married (53.5%) with more than grade XII education (67%). Sixty three (31.5%) women were working due to need and eighty three (41.5%) were finding it difficult to carry out home responsibilities because of it. Extra understanding and support was received from family by 155 (77.5%) and 115 (57.5%) women respectively. One hundred twenty three (61.5%) women felt they did not have enough time for themselves. The status of working women is better than non-working women according to 123 (61.5%) respondents. Financial benefits outweigh other disadvantages according to 105 (52.5%) respondents. Marriage prospects of working women and their children are better than non-working women and their children according to eighty one (40.5%) and eighty (40%) respondents respectively. Confidence in working women is higher than non-working women according to 142 (71%) respondents. Eighty one (40.5%) respondents feel that working women’s financial independence has negative impact on theirs husband’s self esteem. Conclusions: Working women find it difficult to carryout their home responsibilities. There is need for further studies on how to improve the working conditions and home situation for working women in our society
Recurrent Urinary Tract Infections in Renal Transplant Recipients: Risk Factors and Outcomes in Low-resource Settings
Recurrent urinary tract infections (UTIs) after kidney transplantation are a common problem adversely affecting graft outcomes. This retrospective study aimed to report the frequency and risk factors of recurrent UTI and their impact on graft and patient outcomes in kidney transplant recipients at the Sindh Institute of Urology and Transplantation, Karachi, Pakistan, in January-December 2015. Five-year graft and patient survival rates were compared among different groups using Kaplan-Meier analysis. Of the 251 recipients, 67 developed one episode of UTI. Of these 67, 29 had 76 episodes of recurrent UTI. Out of the 76 episodes of recurrent UTI, Escherichia coli was the most common pathogen in 32 cases. Organisms causing recurrent UTI showed resistance to carbapenem in 19 cases versus 2 in the non-recurrent UTI group (P = 0.006). The estimated glomerular filtration rate at 1 year was 57.8 ± 16.23 mL/min/1.73 m2 in the recurrent UTI group vs. 61.9 ± 15.7 mL/min/1.73 m2 in the non-recurrent UTI group (P = 0.001). Graft survival in the recurrent UTI group at 5 years was significantly lower (76%) than in the non-recurrent UTI (95%) and no UTI groups (93%) (log-rank P = 0.006), with no significant effect on patient survival in these groups (P = 0.429). The presence of double-J stent (P = 0.036) and cytomegalovirus infections (P = 0.013) independently predicted recurrent UTI. Recurrent UTIs are common in low-resource settings and adversely affect graft outcomes. Appropriate prophylaxis and treatment are important to reduce recurrent UTI to improve graft outcomes
Density Functional Theory Study of Poly(<i>o</i>‑phenylenediamine) Oligomers
Density functional theory (DFT) and time-dependent DFT
(TD-DFT)
calculations have been performed to gain insight into the structure
of polyÂ(<i>o</i>-phenylenediamine) (POPD). Both reported
structures of POPD, ladder (L)- and polyaniline (P)-like, are investigated
theoretically through the oligomers approach. The simulated vibrational
properties of 5POPDÂ(L) and 5POPDÂ(P) at B3LYP/6-31G (d) along with
their assignments are correlated with experimental frequencies. Vibrational
spectra show characteristic peaks for both POPDÂ(L) and POPDÂ(P) structures
and do not provide any conclusive evidence. Excited-state properties
such as band gap, ionization potential, electron affinities, and HOMO–LUMO
gaps of POPDÂ(L) and POPDÂ(P) from monomers to five repeating units
are simulated. UV–vis spectra are simulated at the TD-B3LYP/6-31+G
(d, p) level of theory, supportive to the ladder-like structure as
the major contributor. Comparison of the calculated data with the
experimental one strongly suggests that the ladder-like structure
is the predominant contributor to the molecular structure of POPD;
however, a small amount of POPDÂ(P) is also believed to be present
