RESUMEN
INTRODUCTION: Addiction refers to the irresistible urge to engage in certain actions or dependence on a particular substance despite knowing negative consequences. The current study evaluated the severity of Smartphone addiction and the factors associated with cell phone-like activity. MATERIALS AND METHODS: This cross-sectional study was conducted from July to August 2019 among medical and dental students in Karachi, Pakistan. A pretested self-administered questionnaire was used among 400 students. The mobile phone addiction was assessed using a 20-item, Mobile Phone Addiction Scale. A two-stage cluster analysis was used to assess mobile phone addiction-like behaviours. Chi-square test was used to find associations between categorical variables. Kolmogorov-Smirnov to test normality of data were also used. A P < 0.05 was considered to be statistically significant for all tests. RESULTS: Out of the total 400 students, the majority 316 (79%) comprise female students. The mean age was 20.54 ± 1.59 years. In 184 (48%) students, there was evidence of mobile phone addiction-like behavior. The prevalence was higher in female than male students and among older compared to adolescent students; the differences were statistically nonsignificant. A higher median score ≥ of 4 is found in questions related to components reflected intense desire, impaired control, and tolerance and harmful mobile use. CONCLUSION: This study highlights that a large number of students are addicted to their smartphones. Smartphone addiction continues to be the most problematic addiction aided by the presence of intense desire, impaired control tolerance, and harmful mobile use. The phenomenon must be fully understood to draw deeper and richer inferences about the origins of this addictive behavior, which is becoming more prevalent in our Pakistani society on a daily basis.

Introduction Electrolyte disturbances are commonly reported in acute stroke in studies conducted in the western world. Presently, the data available about the prevalence of electrolyte disturbance in patients with stroke are not sufficient, especially from developing countries. The purpose of our study is to determine the frequency of occurrence of electrolyte imbalance in patients presenting with acute stroke in a tertiary care hospital. Methods This descriptive cross-sectional study was conducted in the department of internal medicine and neurology in a tertiary care hospital, Pakistan, from December 2019 to March 2021. A total of 300 patients, aged between 30 and 70 years, with either ischemic or hemorrhagic stroke, as diagnosed on contrast tomography (CT) scan of the head or magnetic resonance imaging (MRI) of the brain, were enrolled in the study. The biochemical analysis of the stroke patients was done. Results Out of the 300 participants, 139 (46.3%) participants were from the ischemic stroke group while 161 (53.7%) were from the hemorrhagic stroke group. The mean sodium level was significantly lower in the ischemic group as compared to the hemorrhagic group (129.41 ± 3.12 mEq/L vs. 134.42 ± 3.46 mEq/L; p-value: <0.0001). Potassium level was significantly higher in the hemorrhagic group compared to the ischemic group (6.27 ± 1.12 mmol vs. 4.31 ± 0.71 mmol; p-value: <0.0001). Conclusion Patients coming to emergency with stroke should be screened immediately for electrolyte imbalance. Early identification of rapid imbalances of serum electrolytes may aid in prompt medical intervention and resultant improved outcomes in stroke patients. It is crucial that electrolyte imbalances in these patients are closely monitored to avoid any complications.
RESUMEN
Background and objective The recent emergence of new molecules like angiotensin receptor-neprilysin inhibitor (ARNI) has highlighted the need for an update in heart failure (HF) management, as they have proven to yield better patient outcomes compared to the traditional angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker (ACEI/ARB) use. This study aimed to compare HF-related hospitalization and death in patients on either ACEI/ARBs or ARNI in a local setting. Methods This two-arm interventional study was conducted in the cardiology and internal medicine units of a tertiary care hospital in Pakistan from July 2018 to December 2020. After enrollment, participants were randomized into two groups as per 1:1 ratio using an online research randomizer software (https://www.randomizer.org). Group A received 24/26 or 49/51 mg sacubitril/valsartan twice daily for HF. Group B received 2.5 or 5 mg enalapril twice daily. Patients were followed up for 12 months or till the development of an event. Results The sacubitril/valsartan group had significantly fewer HF-related hospitalizations compared to the enalapril group (13.8% vs. 22.4%; p-value: 0.03), with a relative risk reduction (RRR) of 38.3%. The sacubitril/valsartan group had 52% RRR for HF-related deaths compared to the enalapril group. Conclusion Based on our findings, treatment with sacubitril/valsartan was superior to enalapril in reducing the risk of hospitalization and death related to HF. The magnitude of the beneficial effects of sacubitril/valsartan as compared to enalapril on cardiovascular mortality was at least as high as that of long-term treatment with enalapril.
RESUMEN
INTRODUCTION: Atherosclerosis contributes to the underlying pathophysiology for peripheral arterial disease (PAD), coronary artery disease (CAD), and cerebrovascular disease. Several studies have been conducted to demonstrate PAD as a major risk factor for cardiovascular (CV) events, however, the regional data are limited. This study aims to highlight PAD as a major risk factor in CV events in a local setting. METHODS: In this longitudinal study, 400 hypertensive patients with a confirmed diagnosis of PAD were enrolled from the outpatient department of the cardiology unit. Diagnosis of PAD was made using the ankle brachial index (ABI). ABI less than 0.9 was labeled as participants with PAD. Another group of 400 without PAD was also enrolled as the control group from the outpatient department of cardiology unit. Patients were followed up for 12 months or for the development of myocardial infarction (MI). RESULT: Participants with PAD had a significant increased risk of total MI events with a relative risk (RR) of 1.67 (confidence interval, CI 95%: 1.05-2.66; p-value: 0.02). The RR for fatal MI was 2.62 (CI 95%: 0.94-7.29; p-value: 0.06) compared to the participants without PAD, however, it was not significant. CONCLUSION: This study has focused on the risk factors of PAD and has suggested that the patients who have any of the mentioned risk factors should be treated with caution under strict instructions given by doctors. A variety of treatment options is available, but the initial changes should be made in the lifestyle of these patients, making sure the risk factors are being treated.
RESUMEN
Introduction Male and female sexual dysfunction is frequently found in patients with hypertension. Many studies indicate that this is found more frequently in patients treated with beta-blockers rather than due to hypertension itself; however, almost all studies have been done on male population. This study aims to study the effect of two commonly used beta-blockers on sexual function of a hypertensive female patient. Methods This two-arm open-label randomized prospective study was conducted from April 1, 2019 to March 30, 2020 in a tertiary care hospital at Pakistan. One hundred and fifty participants randomized to group A were given nebivolol 5 mg once daily in addition to their current hypertensive treatment. Another 150 participants randomized to group B were given bisoprolol 5 mg once daily in addition to their hypertensive therapy. Sexual function was assessed on day 0 and day 90 using female sexual function index (FSFI). Results The mean sexual score in the nebivolol group significantly improved after day 90 in comparison to day 0 (24.16 ± 2.1 vs. 26.91 ± 2.6; p-value < 0.0001), while no difference in sexual score in bisoprolol group after day 90 was observed (24.14 ± 2.1 vs. 24.12 ± 2.0; p-value = 0.91). Conclusion In this study, nebivolol group was associated with a significant improvement in sexual function. This can be due to additional vasodilation properties and a low risk of sexual side effects associated with nebivolol.
