In the present study using questionnaire data of smokers (n = 323) and non-smokers (n=218)from the patients in the Out Patients Department (OPD) of civil hospital Quetta was collected. Based on smoking history, the study population was categorized into smokers (<25 cigarettes/day), and non-smokers while smokers were further subdivided into three sub-categories based on their ages: up to 35, up to 50, and above 50. The results depicts that the mean hemoglobin (Hb) levels of smokers and non-smokers were 15.9+0.4g/L and 12.6+0.5g/L respectively, which increased progressively with the number of cigarettes consumed per day. It was observed that 0%, 53.11% and 68.92 were suffering from Chest diseases in group 1, 2 and 3 respectively. In case of high blood pressure population belonging to group 1 and 2 showed greater percentage while group 3 showed lower percentage. Increase in the percentage of heart diseases with age and smoking habit was also observed in all three groups which were prominent in group 3. The present study confirms that the smoking had severe effects on health of the smokers causing lungs and heart diseases. Furthermore, the implications could be made that 60% of the total population is smokers which are the indicator in increase attitude of community towards smoking despite many initiative of declaring smoking as taboo by government and tradition of the area.

It is also defined as one of the graduate attributes of higher education for the sample private university where this research was conducted, as it is perceived that CT helps the graduate to become ‘engaged citizens’ in the twenty-first century. Despite the well-documented importance of CT, its assessment remains a challenge. This study addresses this challenge through the systematic development and field-testing of a rubric for assessing critical thinking in a multidisciplinary context in higher education. A multidisciplinary group of faculty (i.e. education, nursing, medicine) from the sample university partnered with a policy research group in Canada to translate this plan into action. The development of the assessment tool followed a multi-step process including: (i) identification of the main elements of CT; (ii) choice of a rubric format; ...

The purpose of this comparison was to assess the ability of PAL in enhancing academic achievement and to consider its addition within the traditional medical syllabus. Methods: A randomized control trial (RCT) was conducted at Department of Community Medicine, Lahore Medical and Dental College in 2014. Convenience sampling was used and out of 125 fourth year MBBS students, those who agreed to take part in the study (N = 99), were randomly allocated to PAL (n = 49) and lecture (n = 50) groups. Community Health & Nutrition was the course chosen for the study. Both lecture and the PAL sessions were conducted simultaneously and the duration and content covered in each session were the same for both groups. Knowledge gained was assessed through a pre-and post-test. Chi-square test, independent t test, paired t test and analysis of covariance (ANCOVA) were used for data analysis. Results: The study participants demonstrated a significant difference in the pre-test and post-test scores in both the study groups (P ≤ 0.001). However, no statistically significant difference was found in the post-test scores between the Lecture and PAL groups, F (1, 95) = 0.584, P = 0.447. Gender and high school qualifications had no bearing on test scores in both learning groups. Conclusion: The present study concludes that in terms of academic achievements, PAL was equally effective to lectures. Therefore, PAL can be incorporated as a supplement to lectures in medical school curricula. Article info Please cite this article as: Daud S, Chaudhry AM, Ali SK.

However, the quality of WFB may be affected by various personal and contextual factors. This study aimed to identify nurse teachers' conceptions and practices of WFB on written assignments in nursing degree offering institutions in Karachi, Pakistan. Methods: A cross-sectional descriptive study design was used to answer the study questions. The study was conducted at 11 nursing schools in Karachi by recruiting those teachers who were teaching in nursing degree programs. The sample size of the study consists of 80 teachers. Universal sampling technique was used to select the subjects of the study. Results: The study result consists of demographic information of the participants, teachers' conceptions and their practices of WFB. Although majority (92%) of the teachers believed that WFB is important for students' learning, they acknowledged that they were not able to provide WFB at optimum level to their students. This gap in practice is attributed to various personal, contextual, and organizational factors; among them, the highest reported factors were teachers' lack of training for provision of WFB (84%), distraction in the environment (78%), and constraints of time due to teacher's workload (74%). Conclusions: The importance of WFB for students' learning is well established in the literature. However, the preparation of teachers and an enabling environment to facilitate teachers for optimum practices of WFB needs considerable attention by educational institutions.

For this purpose, a survey was administered to 150 teachers forming a non-probability sample, who were working in various universities in Karachi. The disciplines chosen for the study included nursing, applied linguistics, medicine and education departments in institutes of higher education situated in Karachi. Before sampling, initial screening was done to obtain a list of institutes which provide written feedback on students' assignments. Two homogenous groups of teachers by discipline (nursing and education) were then selected for focus group discussions. It was found that most teachers consider written feedback an important tool for guiding and helping students improve their work. In fact, they consider written feedback as important as verbal feedback. Teachers also recognized the importance of discussing the written feedback with the students but they rarely did so because of time constraints. Most teachers preferred to directly fix students' errors instead of providing feedback to enable them to correct those errors by themselves. While less than half of the participants used a checklist for grading, others used annotation. Several factors were found to have a great influence on the amount and quality of feedback. The most significant factor was whether teachers had formal training in providing feedback. Only 17% of the participants in this study had proper training to give written feedback. They also identified several environmental and personal factors that had an impact on their feedback practices including time, the relationship between the teacher and individual students, and, most importantly, the policies and culture of the institutes.

The objective of the present study was to determine the association of selected single nucleotide polymorphisms (SNPs) at the 8q24 locus (rs9642880 and rs6983267 at 8q24.21 and rs2294008 near the prostate stem cell antigen [PSCA]) with urothelial bladder cancer (UBC) among the Pakistani population. For this purpose, genotyping of selected SNPs was performed by simple allele-discriminating polymerase chain reaction (PCR) in 200 UBC cases and 200 healthy controls. All three variants were found to be associated with a significantly increased UBC risk (p<0.05) after adjusting for age, gender and smoking. rs9642880 was found to be associated slightly stronger with low grade as compared to high grade UBC, while rs2294008 was associated with increased risk of high grade and invasive stages of the disease, and rs6983267 exhibited a strong positive association with UBC risk irrespective of tumor stage and grade. In conclusion, the current study shows a significant involvement of the 8q24 locus in UBC etiology in Pakistani patients.

The study also explored other supporting ecological factors like metal content analysis and current soil status (pH, moisture content, organic matter, soil texture) of the orchard’s soil. This investigation revealed that all physico-chemical parameters were supporting production but it declined mainly due to drastic climate change aspects including unusual seasonal variations, elongated summer periods and unusual rainfall periods. In context of questionnaires results, an overwhelming number of farmers (91%) were of the opinion that climate change was the main factor behind decline apple production. The case study served as an effort to bring awareness in the local farmers abou...

Methods: The study was cross-sectional comparative comprising of 120 subjects, of whom 60 were the first degree asymptomatic relatives of non-asthmatic patients. Portable office spirometry was carried out along with pollen count on the same day taken from the meterological department data. Result: The spirometric variables like PEFR, FEV1, FEV6 and FEV1/FEV6 were deranged as pollen count increased. The changes in these variables were found to be present before development of clinical signs and symptoms of pollen allergy. Conclusion: High risk individuals like first-degree relatives not having symptoms of pollen allergy show decrement in pulmonary function tests parameters during high pollen count seasons. Key Words: Pollen Allergy, First degree relative, Portable...

Methods: This cross sectional (descriptive) study included sixty known asthmatics, of either sex and of all ages. Pollen count as per cubic meter was recorded daily during February to May as reported by meteorological department. History, clinical examination and lung function tests were recorded in each case. The Pulmonary Function Test (PFT) with pollen count of asthmatic patients was correlated. Results: The PFT of asthmatic patients were adversely affected significantly during pollen season. There was negative correlation of moderate strength with FEV1 in asthmatic patients with high air borne pollen count during the pollen season. Conclusion: Spirometry was shown to be an effective technique to study the pollen allergy problem in already asthmatic patients.

Presence of large amount of pollens in the air poses serious implications on pollinosis. In the month of March highest daily pollen count was observed. This revealed a correlation of pollen count with optimum range of temperature for flourishing and dispersing of pollen grains. General trend between pollen count release and the number of allergy patients was found in accordance suggesting a high pollen risk for the residents and the visitors during peak time of the year.

A total of 162 plant species representing 137 genera and 58 families were recorded. Two way indicator species analysis (TWINSPAN) classified the floristic species composition into four major community types which showed some overlap in an ordination space, reflecting relatively homogenous nature of the vegetation. Pinus roxburghii and Grewia asiatica were more prevalent in green belts while native vegetation dominated by Dalbergia sissoo and Acacia nilotica were present in undisturbed green spaces. Broussonetia papyrifera and Populus euphratica showed distribution along the drains/nullahs in the city. Detrended Correspondence Analysis (DCA) was applied to identify environmental gradients to define vegetation distribution. First ordination axis demonstrated species distribution influenced by presence of invasive species whereas second axis ide...

POAG and PCAG patients recruited from different areas of Pakistan were diagnosed on the basis of clinical history, raised intraocular pressure (IOP), cup-to-disc ratio (CDR) and visual field defects. Their blood was collected and genomic DNA was extracted from it, followed by PCR amplification and VNTR typing of the eNOS gene, while the HSP70 SNP was analyzed with PCR-RFLP. For both of the polymorphisms, the genotype distribution of the POAG and PCAG patients was compared with unaffected controls. HSP70 polymorphism was found to be significantly associated with PCAG (chi(2)=15.29 [p<0.001], OR=2.63 [95% CI=1.55-4.48]), with p<0.001 for the dominant model and OR=2.09 (95% CI=1.10-3.96) , with…

The objective of the present study was to determine the association of selected single nucleotide polymorphisms (SNPs) at the 8q24 locus (rs9642880 and rs6983267 at 8q24.21 and rs2294008 near the prostate stem cell antigen [PSCA]) with urothelial bladder cancer (UBC) among the Pakistani population. For this purpose, genotyping of selected SNPs was performed by simple allele-discriminating polymerase chain reaction (PCR) in 200 UBC cases and 200 healthy controls. All three variants were found to be associated with a significantly increased UBC risk (p<0.05) after adjusting for age, gender and smoking. rs9642880 was found to be associated slightly stronger with low grade as compared to high grade UBC, while rs2294008 was associated with increased risk of high grade and invasive stages of the disease, and rs6983267 exhibited a strong positive association with UBC risk irrespective of tumor stage and grade. In conclusion, the current study shows a significant involvement of the 8q24 locus in UBC etiology in Pakistani patients.
