RESUMO
Background Ischemic stroke (IS) is a fatal complication of acute coronary syndrome (ACS). Factors that speed up IS development after ACS are understudied, especially in developing countries like Pakistan. Thus, this study was designed to identify the potential risk factors of IS in patients with a preceding episode of ACS. Methodology This retrospective study was performed on 208 patients whose ACS and its consequent complications such as IS were managed in the cardiac and neurology units of Benazir Bhutto Hospital, Rawalpindi, from January 2022 to March 2023. Patients were enrolled via consecutive sampling and pre-defined inclusion and exclusion criteria. Before data collection, informed consent and ethical approval were obtained. Data were retrieved from the medical records of the patients. A self-structured proforma was applied to collect data. SPSS version 25 (IBM Corp., Armonk, NY, USA) was used for data analysis. The study variables between patients with and without IS were compared using descriptive and inferential statistics. The association between IS and its possible risk factors in patients who had previously experienced ACS was determined using multivariate logistic regression. Results Of the 208 enrolled patients, 24 (11.54%) had IS following ACS. Sedentary lifestyle (odds ratio (OR) = 3.099, 95% confidence interval (CI) = 1.025~4.219, p = 0.009), hypertension (OR = 3.060, 95% CI = 1.798~4.876, p = 0.002), diabetes mellitus (OR = 2.899, 95% CI = 1.126~4.112, p = 0.009), dyslipidemia (OR = 2.907, 95% CI = 1.332~4.254, p = 0.007), history of smoking (OR = 2.760, 95% CI = 1.234~4.122, p = 0.018), and non-adherence to ACS medication (OR = 2.966, 95% CI = 1.300~4.266, p = 0.030), were the risk factors of IS among patients with preceding ACS. Conclusions In the study population, the incidence of IS following ACS was significant. Sedentary lifestyle, hypertension, diabetes mellitus, dyslipidemia, smoking history, and non-compliance with ACS therapy all played a significant role in the development of IS in patients with prior ACS. Proper management of ACS and associated risk factors could lead to the prevention of serious complications such as IS.
RESUMO
Background Coronary artery disease (CAD) is one of the major causes of death all over the world. Its severity evaluation through the Gensini scoring system is quite a complex process as these score systems require complex investigations and cardiologists. Therefore, this study aimed to determine the predictive capacity of neutrophil-to-lymphocyte ratio (NLR) for the severity of CAD in patients with myocardial infarction. Methods This cross-sectional study was performed on 208 patients with acute myocardial infarction whose coronary angiography was performed in the Department of Cardiology of Benazir Bhutto Hospital (BBH), Rawalpindi, Pakistan during the period of one year from January 2022 to March 2023. The enrollment of patients was made through purposive sampling and established inclusion and exclusion criteria. Ethical approval and informed consent were acquired before the data collection. Data was collected through a self-structured form. Vessel score and Gensini score were applied for the assessment of the severity of CAD. Patients were divided into two groups based on the Gensini score system. Data analysis was carried out in the Statistical Package for the Social Sciences (SPSS) version 25 (Released 2017; IBM Corp., Armonk, New York, United States). Both descriptive and inferential statistics were used to compare the study variables between the patients with non-severe CAD and patients with severe CAD. Pearson's correlation was used to determine the correlation between the NLR and the severity of CAD. A linear regression model was applied to evaluate the predictive capacity of the NLR for the severity of CAD. A p-value less than 0.05 was set as statistically significant. Results Out of 208 patients, 128 (61.53%) patients had non-severe CAD while 80 (38.47%) patients had severe CAD. Significant differences were observed in the Gensini mean scores, NLR values, and in the frequencies of hypertension, diabetes mellitus, dyslipidemia, and history of smoking, with p≤0.05 for all these variables, between the non-severe CAD group and severe CAD group. NLR was significantly correlated with the severity of CAD (p-value=0.001). Pearson's correlation coefficient was 0.71 for NLR with the Gensini scores. The simple linear regression model was valid (the p-value of the F test was <0.000), with beta coefficients of 2.60 (p=0.002) for NLR. The R2 value was 0.80 (80%). Conclusions In the current study, a significant percentage of patients had severe CAD. Furthermore, a positive and significant association was noted between the NLR with the severity of CAD. This present study suggests that NLR is a reliable predictor of CAD severity; therefore, it could be used for risk stratification of cardiac patients with CAD.
RESUMO
Background Knee osteoarthritis (KOA) is the most typical cause of knee pain and impairment worldwide. It is typified by slow and progressive degeneration of the articular cartilage of the knee joint. Although KOA is being managed with a variety of therapies, the comparison of the effectiveness of different intra-articular injections in KOA treatment in Pakistan is still not thoroughly investigated. Therefore, the purpose of this current study is to compare the efficacy of intra-articular administration of platelet-rich plasma (PRP) and corticosteroids (CSs) in the treatment of KOA. Methods This prospective comparative study was performed among one hundred patients diagnosed with KOA in Benazir Bhutto Hospital, Rawalpindi, for one year from April 2022 to March 2023. Specified inclusion and exclusion criteria were employed for patient enrollment. Patients were divided into two equal groups through simple random sampling. Group A patients received an intra-articular injection of PRP solution whereas group B patients received an intra-articular injection of CSs. Informed consent and ethical approval were also acquired prior to data collection. A self-designed proforma based on interviews was used to collect data. The data analysis in Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 25.0, Armonk, NY) was carried out via descriptive statistics and an independent t-test. Results Women (N=71, 71%) had a higher prevalence of KOA than men (N=29, 29%). The means of study variables like age, Visual Analog Scale (VAS) score, and Western Ontario and McMaster Universities (WOMAC) score were 56.10 ± 8.70 years, 8.08 ± 1.6, and 70.08 ± 8.76 respectively. The frequency of KOA on the right side was 62% (N=62) while it was 38% (N=38) on the left side. In the study population, 69% (N=69) patients had grade II KOA, and 31% (N=31) patients had grade III KOA. At the first-month, second-month, and third-month follow-up visits, there were statistically significant differences in the mean scores of the WOMAC and VAS between the study groups. However, at the first-month follow-up visit, mean scores of VAS and WOMAC were lower in group B than in group A while these were lower in group A as compared to group B, at the second-month and third-month follow-up appointments. Conclusions Intra-articular infiltration of both PRP and CSs was efficacious in the treatment of KOA-related pain and functional limitations; however, overall improvement in the PRP group was higher than CS group.
RESUMO
Background Postoperative acute heart failure (AHF) in elderly patients after hip fracture surgery is a common complication. Therefore, this study aimed to identify the risk factor of AHF after hip fracture surgery among the older population. Methods This retrospective cohort study was performed on 88 admitted patients whose hip fractures were fixed via internal fixation surgery in a tertiary care hospital in Rawalpindi, Pakistan, from January 2022 to March 2023. Recruitment of patients was made through established inclusion and exclusion criteria. Ethical approval and informed consent were also gained before the data collection. A self-designed form was used to collect data. Data analysis was carried out in the IBM SPSS Statistics for Windows, Version 25 (Released 2017; IBM Corp., Armonk, New York, United States). Both descriptive and inferential statistics were applied to compare the attributes of the patients with AHF and patients without AHF. Multivariate logistic regression was used to evaluate the association between the postoperative AHF and its potential risk factors. Results Out of 88 enrolled patients, 12 (13.64%) had developed postoperative AHF. Age ≥ 65 years (OR = 2.606, 95% CI = 1.035~4.160, p = 0.010), anemia (OR = 3.178, 95% CI = 1.847~5.990, p = 0.029), hypertension (OR = 2.019, 95% CI = 1.110~4.034, p = 0.012), diabetes mellitus (OR = 2.003, 95% CI = 1.115~4.012, p = 0.015), hypoalbuminemia (OR = 2.486, 95% CI = 1.218~4.619, p = 0.030), and operation time ≥ 120 minutes (OR = 1.702, 95% CI = 1.099~2.880, p = 0.018), were the risk factors of postoperative AHF in elderly patients after hip fracture surgery. Conclusions In the study population, the incidence of postoperative heart failure was significant and age ≥ 65 years, anemia, hypertension, diabetes mellitus, hypoalbuminemia, and operation time ≥ 120 were significantly involved in the development of it. Preoperative identification and management of AHF risk factors could lead to the prevention of postoperative complications.
RESUMO
Background Vitamin D (VD) deficiency is common in patients with type 2 diabetes mellitus (T2DM). VD deficiency and its associated factors are understudied in Pakistan. This study aimed to estimate the incidence of VD deficiency and its association with microalbuminuria in patients with T2DM. Methods This descriptive cross-sectional study was performed on 110 patients diagnosed with T2DM aged between 30 and 65 years in the outpatient department clinic of diabetes in Benazir Bhutto Hospital, Rawalpindi, for around eight months from November 2022 to June 2023. Non-probability sampling technique and established inclusion and exclusion criteria were used for patient recruitment. Ethical approval and informed consent were also waived before data collection. Data collection was done by an interview-based and self-designed questionnaire. Data analysis was carried out via descriptive statistics along with chi-square, independent-samples t-test, and Pearson correlation in Statistical Package for the Social Sciences (SPSS) version 25 (Armonk, NY: IBM Corp.). Results The means of the study population for age, serum VD, and UACR (urine spot for albumin-to-creatinine ratio) were 48.50±15.67 years, 28.16±15.34 ng/mL, and 29.69± 87.22 µg/mg, respectively. The incidences of VD deficiency and microalbuminuria in the study population were 43.64% and 28.20%, respectively. VD deficiency was significantly associated with age group (p=0.002), gender (p=0.008), and albuminuria status (p=0.004). The comparison of means of UACR between the VD deficiency group and the non-VD deficiency group was also significant (0.001). VD deficiency was higher among older age groups, female gender, and patients with microalbuminuria. A significant negative correlation between serum VD level and UACR (microalbuminuria) (p=0.002) was present. Conclusion VD deficiency incidence was notably high in the study population. Older age, female gender, and microalbuminuria were found to elevate the VD deficiency to a crucial level. Serum VD deficiency and microalbuminuria were significantly and negatively correlated. Therefore, VD level should be monitored intermittently in T2DM, so that we could prevent the progression of T2DM timely.
RESUMO
Background Knee osteoarthritis (KOA) is a chronic and progressive disease of the knee joint characterized by articular cartilage destruction. It is the most common cause of knee disability and pain globally. Various treatments are used for the management of KOA; however, the role of intra-articular injections in KOA management in Pakistan remains understudied. Therefore, this study aims to evaluate the effectiveness of intra-articular injections of hyaluronic acid (HA) and corticosteroids in the management of KOA. Methodology This randomized, prospective, comparative study was conducted among 88 patients diagnosed with KOA in the outpatient department clinic of orthopedics in Benazir Bhutto Hospital, Rawalpindi, from January 2022 to January 2023. For patient enrolment, structured inclusion and exclusion criteria and a simple random sampling technique were used. Before data collection, ethical approval and informed consent were obtained. Data collection was done via a self-structured and interview-based proforma. Data analysis was performed through descriptive statistics and independent t-tests using SPSS version 25 (IBM Corp., Armonk, NY, USA). Results KOA was more prevalent in women (60, 68.18%) than men (28, 31.82%). The means for study variables such as age, Visual Analog Scale (VAS) score, and Western Ontario and McMaster Universities (WOMAC) score were 58.08 ± 7.89 years, 7.66 ± 1.8, and 71.86 ± 8.90, respectively. The incidences of right-sided and left-sided KOA were 57 (64.77%) and 31 (35.23%), respectively. Likewise, the frequency of grade II KOA was 55 (62.50%), while the frequency of grade III KOA was 33 (37.50%). Differences in the mean scores of both VAS and WOMAC between study groups were statistically significant at the second-week, sixth-week, and third-month follow-up visits. However, the mean scores of VAS and WOMAC were lower in group B than in group A at the second-week follow-up visit, whereas the scores were lower in group A compared to group B after the sixth week and third month of intra-articular injections. Conclusions Intra-articular injections of both HA and corticosteroids were adequately effective in the management of KOA-associated pain and functional restrictions; nevertheless, the benefits of corticosteroids were acute and short-term, whereas the outcomes of HA were gradual and long-term.
RESUMO
Background and objectives Microalbuminuria prevalence is high in patients with type 2 diabetes mellitus (T2DM) all over the world and its prevalence is affected by several factors. In Pakistan, microalbuminuria and factors that play a role in its development in patients with T2DM are under-researched. This study aimed to determine the incidence of microalbuminuria and the factors affecting it in patients with T2DM. Material and methods This descriptive cross-sectional study was performed on 129 diagnosed patients with T2DM in the outpatient department of Benazir Bhutto Hospital, Rawalpindi, for approximately six months from August 2021 to January 2022. Patients were recruited in the study through a non-probability consecutive sampling technique and established inclusion and exclusion criteria. Ethical approval was obtained from the relevant hospital ethical review board (ERB). After explaining the study's aims, informed consent was also taken from all patients before the start of data collection. A self-structured and interview-based questionnaire was used for the collection of data. Descriptive statistics and a chi-square test were applied for the data analysis using Statistical Package for the Social Sciences (SPSS) version 25 (Armonk, NY: IBM Corp.). Results The incidence of microalbuminuria in the study population was 31.78%. The association between microalbuminuria and age (p = 0.002), gender (p = 0.003), duration of diabetes mellitus (p = 0.001), therapy type (p = 0.03), control of diabetes mellitus, (p = 0.001), and hypertension (p = 0.002) was statistically significant. Higher age group, male gender, longer duration of diabetes mellitus, oral hypoglycemic agents, poorly controlled diabetes mellitus, and history of hypertension, all were found to raise the incidence of microalbuminuria. Even though being overweight was also found to raise the incidence of microalbuminuria, the association between microalbuminuria and nutritional status was statistically insignificant (p = 0.05). Conclusion Microalbuminuria incidence is significantly high in the study population. The factors such as increasing age, male gender, longer duration of the diabetes mellitus, oral hypoglycemic agents, poorly controlled diabetes mellitus, and history of hypertension, all raise the incidence of microalbuminuria in patients with T2DM to a statistically significant extent. Screening of microalbuminuria patients with T2DM should be added to the routine investigations for diabetes mellitus for the early detection of renal and cardiovascular complications.
RESUMO
Background Nephrolithiasis (renal stones) is the most common urological disease. Its prevalence is high in every part of the world. Several factors lead to renal stone formation. In Pakistan, nephrolithiasis prevalence is also high as Pakistan is located in a region which is known as the salt belt. However, nephrolithiasis and its possible risk factors are under-researched in Pakistan. Objective This study aims to identify the risk factors for nephrolithiasis among admitted patients with renal stones. This may lead to a reduction in renal stone incidence and its allied complications by the prevention of risk factors that would have a major role in renal stone formation. Material and methods This descriptive cross-sectional study was performed among the 143 admitted patients with renal stones in the urology ward of Benazir Bhutto Hospital, Rawalpindi, for approximately six months from November 2021 to April 2022. Non-probability convenient sampling and developed inclusion and exclusion criteria were used for the recruitment of patients. After elaborating on the objectives, the study data were collected by interviewers through a self-structured questionnaire. Descriptive analysis was carried out using SPSS version 25.0 (IBM Corp., Armonk, NY). Results Nephrolithiasis was more prevalent among patients who had an age group range of 15-30 years (47.55%), male gender (56.65%), illiterate educational status (53.14%), lower socioeconomic status (66.43%), inadequate intake of water (61.53%), used tap water (56.64%), a habit of daily vegetable intake (65.04%), sedentary lifestyle (51.74%), family history of renal stones (57.34%), no diabetes mellitus (62.94%), no hypertension (52.45%), and overweight (48.23%). Conclusion In brief, the age group of 15-30 years, male gender, illiteracy, lower socioeconomic status, insufficient water intake, tap water, high vegetables, inactive lifestyle, family history of nephrolithiasis, and a high BMI all increase the risk of nephrolithiasis.
RESUMO
Background Several recent studies have shown that the hepatitis C virus (HCV) and its different genotypes are a predominant and leading cause of cirrhosis and splenomegaly in different regions of the world. Advanced stage of cirrhosis leads to portal hypertension that causes splenomegaly. This complication may have many other manifestations such as anemia, infections, and bleeding disorders in severe stages. This study aimed to determine the effect of different HCV genotypes on the development of splenomegaly and to assess which HCV genotypes are more associated with it. Materials and methods A total of 483 conveniently sampled HCV patients were included in this descriptive cross-sectional study. Six genotypes (1, 2a, 2b, 3a, 3b, and mixed) were studied, and 80 patients for each of these genotypes were included. Data were collected from patient medical records regarding patient demographic details, HCV serology and genotyping, and sonographic size of the spleen. Results In total, splenomegaly was present in 14.1% (n=68) patients. The development of splenomegaly was significantly associated with old age, as 25.2% (n=26) of patients above 60 years of age (n=103) developed splenomegaly (P=0.005). Our study determined that splenomegaly was significantly related to HCV genotypes 3a, 3b, and 1 (P<0.001, P=0.017, and P=0.019, respectively). By taking mixed genotype as a reference, the odds of developing splenomegaly with genotype 3a were the highest (OR = 9.481; CI=95%). Conclusions Our study concludes that HCV genotype 3a, 3b, and 1, and age above 60 years have a significant association with splenomegaly. Genotype 3a has the highest risk of developing splenomegaly. Therefore, our study demands screening, early diagnosis, and prompt treatment of these particular HCV genotypes to prevent complications and risk of mortality.
RESUMO
Background Medical students face greater academic stress and devote more time to their studies due to the tough nature of medical education, at the cost of sleep and physical activity. Good sleep quality and physical activity improve the mental ability and academic performance of the students. Objectives and rationale The study aims to assess sleep quality and physical activity levels among fourth-year MBBS students of Rawalpindi Medical University. We compare these levels with gender and boarding status and correlate them with the academic performance of the students. This may provide new target areas to improve the academics of students performing below average. Materials and methods It was a descriptive, cross-sectional study conducted in March 2019 on 344 medical students enrolled in the fourth-year MBBS class of Rawalpindi Medical University. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI), physical activity levels by the Global Physical Activity Questionnaire (GPAQ), and academic performance by the marks attained in the most recent pathology class test. The students who could not prepare for the test in the usual manner were excluded from the study. Two-hundred nineteen (219) students were part of the final study sample. Data analysis was performed using SPSS v.22.0 (IBM Corp, Armonk, NY, US). A chi-squared test, independent samples t-test, Pearson's correlation, and a multiple linear regression model were used to assess the variables. Results Sleep quality and physical activity were significantly correlated with academic performance (p-values of the chi-square and t-test were <0.000). Pearson's correlation coefficient was -0.69 for PSQI (p<0.000) and 0.62 for GPAQ (p 0.003) with test scores. Gender showed significant association with sleep and physical activity levels (male students had better physical activity level and poorer sleep quality than female students) but no association with test scores. Boarding status was significantly associated with all three variables. Boarders had lower mean test scores and poorer sleep and physical activity indices as compared to non-boarders. The multiple linear regression model was valid (p-value of the F test was <0.000), with beta coefficients of -2.53 ( p=0.002) for sleep quality and 1.37 (p=0.01) for physical activity. The R2 value was 0.84 (84%). Conclusions Our study indicates an overall poor sleep quality and physical activity level among fourth-year medical students, particularly boarding students, who have lower test scores and worse sleep and physical activity levels. In general, male students have better GPAQ scores and female students have better PSQI scores. Both the PSQI and GPAQ scores are significantly correlated with test scores and provide potential target areas to improve the exam performance of the students.
