Clinical trials landscape in a lower-middle-income country (Pakistan).

In recent times, there have been calls from within the developing nations for increased ownership by governmental research bodies and universities of the priority research setting and research that aligns with national health strategies. This is a review paper of the studies that have been published on clinical trials in developing countries, with a focus mainly on Pakistan. The literature review used online databases such as PubMed, Scopus, and Google Scholar, World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), and ClinicalTrials.gov trial registries to search for clinical trials conducted in Pakistan between January 2000 and December 2022 and analyzed. The results revealed that clinical research in Pakistan is hindered by a number of barriers, including a lack of funding, skilled personnel, and regulatory issues. Lack of funding is a common obstacle, and the majority of funding for clinical trials originates from Western countries or pharmaceutical companies established in the West. In conclusion, clinical studies in developing countries, especially in Pakistan, are hindered by a plethora of barriers, and to improve the current state, increasing funding, streamlining ethical approval procedures, simplifying regulatory systems, addressing cultural and religious concerns, and participating in global efforts to bridge the gap in health-based research are crucial.

Frequency of migraine and its associated triggers and relievers among medical students of Lahore: a cross-sectional study.

Introduction: Headache is a widely prevalent illness that negatively impacts people's lives, leaving them functionally incapable of performing regular everyday tasks. The global burden of headache is 40%, of which migraine accounts for 47%. Objective: This study aims to determine the frequency of migraine among medical students of Lahore and its characteristics, associated triggers, and relievers among medical students. Methodology: A cross-sectional study was conducted in medical colleges after obtaining ethical approval. Migraine was diagnosed using the criteria provided in the International Classification of Headache Disorders, Third Edition (ICHD-3), and data on triggers, relief, and demographics were collected. The information is analyzed using SPSS 22. Result: The data were collected from 522 medical students. The average age of the students was 21.3 ± 2.0 SD (in years). About 146 (28.0%) of the medical students have migraine according to ICHD-3 criteria and were diagnosed initially. Gender was insignificantly associated with migraine (P-value=0.32). Students with psoriasis, hypertension, and polycystic ovarian syndrome were statistically significantly related to migraines with a P-value=0.002. Dehydration is the most frequent aggravator, and adequate sleep is the most frequent reliever of migraine. Conclusion: The findings show a high frequency of migraine. They are similar in both genders, depicting that stressful lifestyles, inadequate sleep patterns, and bizarre dietary habits make them more prone to migraine episodes. So, further, detailed studies should be done on evaluating triggers and relievers of migraine and their interrelations with migraine so we can focus on preventive strategies, diagnosis, and treatment of migraine.

Association of serum digoxin concentration with morbidity and mortality in patients with atrial fibrillation, heart failure and reduced ejection fraction of 45 % or below.

BACKGROUND: Atrial fibrillation (AF) and heart failure with reduced ejection fraction (HFrEF) are common cardiovascular conditions linked to significant health burdens. This review aims to study the relationship of serum digoxin concentration and mortality and morbidity outcomes in defined population. METHODS: We conducted a thorough search of databases such as PubMed, Google Scholar, and Cochrane Library, from inception until 20th Aug 2023. Studies that explored the relationship between serum digoxin concentration and mortality, morbidity, or other clinical endpoints in AF and HFrEF patients (ejection fraction ≤45 %) were eligible for inclusion. RESULTS: The selected studies exhibited a wide range of designs, patient cohorts, and measured outcomes. The association between serum digoxin concentration, mortality and morbidity endpoints like hospitalization rates and cardiovascular events were assessed in these studies. Despite the methodological diversity, our systematic review uncovered consistent trends across the studies, suggesting that elevated serum digoxin concentrations may correlate with higher mortality and morbidity in AF and HFrEF patients. CONCLUSION: This systematic review emphasizes the need for cautious management of serum digoxin levels in patients with concurrent AF and HFrEF. While digoxin remains a valuable treatment for heart failure, its potential adverse effects on outcomes in this specific patient subgroup call for vigilant monitoring and individualized treatment approaches. Further research is required to elucidate the dose-response relationship and potential confounding factors influencing outcomes associated with serum digoxin concentration in AF and HFrEF patients. Clinicians should consider these findings when making therapeutic decisions to enhance patient care and outcomes.

Rethinking HDL-C: An In-Depth Narrative Review of Its Role in Cardiovascular Health.

The interplay between HDL-C and LDL levels are closely intertwined with the cardiovascular system. High-Density Lipoprotein Cholesterol (HDL-C) is a well-known biomarker traditionally being interpreted as higher the HDL-C levels, minimal the risk of adverse cardiovascular disease (CVD) outcomes. However, recent research has unveiled a more complex relationship between HDL-C levels and cardiovascular outcomes, including genetic influences and potential risks associated with extremely high HDL-C levels. Intriguingly, extremely high HDL-C levels have been linked to unexpected cardiovascular risks. Up To date research suggests that individuals with genetically linked ultra-high HDL-C levels may depict an increased susceptibility to CVD, challenging the conventional realm that higher HDL-C is always beneficial. The mechanisms underlying this mystery are not fully understood but may involve HDL particle functionality and composition. In a nutshell, the relationship between HDL-C levels and cardiovascular outcomes is multifactorial. While low HDL-C remains a recognized risk factor for CVD, the genetic determinants of HDL-C levels add complexity to this association. Furthermore, extremely high HDL-C levels may not exhibit the expected protective benefits and may even pose unprecedented cardiovascular risks. A comprehensive understanding of these dynamics is essential for advancing our knowledge of CVD risk assessment and developing targeted therapeutic interventions. Further studies are needed to unravel the intricacies of HDL-C's role in cardiovascular health and disease.

Acute kidney injury in birth asphyxiated patients: A cross sectional study at Bahawal Victoria Hospital.

BACKGROUND: The presence of perinatal asphyxia and its severity appear to correlate with increasing incidence of Acute kidney injury (AKI). The objective of this study is to determine the frequency of AKI and its outcome in birth asphyxia. METHODS: This cross-sectional study was carried out in the Department of Pediatric Medicine from March 2019 to September 2019. A total of 111 newborns with birth asphyxia of gestational age 37-41 weeks were included. Neonates born to mothers having hypertension and diabetes mellitus, patients with congenital kidney anomalies like polycystic kidney disease and renal agenesis, and mothers taking nephrotoxic drugs or any other known cause of AKI like hypovolemic shock were excluded. Urine output (UOP) and final outcome of the patient were also noted. AKI was noted. RESULTS: The mean gestational age was 38.29 ± 1.07 weeks. The mean weight of neonates was 3.08 ± 0.31 kg. The frequency of AKI in birth asphyxia was 20 (18.02%) neonates. Complete recovery in AKI patients was seen in 07 (35.0%) and death in 13 (65.0%) patients. CONCLUSION: This study has shown that the frequency of AKI in birth asphyxia was found in 18.02% neonates with complete recovery seen in 35.0% and death in 65.0% patients.

Assessing the Predictive Efficacy of Lok Score in Identifying Esophageal Varices in Liver Cirrhosis Patients: A Cross-Sectional Study.

Introduction Liver cirrhosis is a global health concern with various etiologies, leading to portal hypertension and gastroesophageal varices. Variceal bleeding, a severe complication of cirrhosis, necessitates early detection and intervention to reduce mortality. Endoscopic screening is the gold standard for varices detection but is invasive and expensive. This study evaluates the Lok Score, a non-invasive predictive tool, for identifying esophageal varices in patients with liver cirrhosis. Materials and methods A cross-sectional study involving 150 liver cirrhosis patients was conducted. The Lok score was calculated using specific parameters. Patient data, including age, gender, etiology of liver cirrhosis, Child-Pugh class, varices presence, and grades, were recorded. Statistical analysis was performed using IBM Corp. Released 2013. IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp., and diagnostic parameters for Lok Score were computed. Results The study demonstrates that the Lok score exhibits significant potential as a predictive tool for esophageal varices. The mean Lok score significantly differed between individuals with and without varices, suggesting a correlation between Lok score and varices presence. Higher Lok scores may indicate more advanced varices. Utilizing the Lok score in clinical practice could lead to timely interventions, improving patient outcomes. Conclusion The Lok score shows promise as a valuable predictive tool for esophageal varices in liver cirrhosis patients. Early identification using this non-invasive parameter can aid in risk stratification and guide appropriate management strategies. However, further validation and larger studies are needed to fully integrate the Lok score into clinical practice for the benefit of cirrhosis patients.

A dilemma of patients: poor quality administration of tertiary care hospitals: a cross-sectional study.

Introduction: The study focuses on healthcare delivery standards in Pakistan's tertiary care hospitals. Poor accountability and a lack of financial and human resources are the main contributing factors to a hospital's substandard performance and low patient satisfaction rates. Feedback surveillance forms are the Achilles tendon in the quality improvement of a facility, and this practice is, unfortunately, not widely practiced in the hospitals of Pakistan. Through this paper and experience, the authors hope to shed light on the need for regular feedback surveys and implementing their results to improve healthcare quality. Settings and Design: A prospective, observational study of seven tertiary care hospitals in Pakistan. Materials and Methods: The data was collected using a survey form. Each survey form was filled out by a team comprising three public health professionals who observed the hospital and its functioning without interfering with its workings. The questionnaire was developed with the help of Tools for Assessing the Operationality of District Health Systems: Health Facility Questionnaire designated in the respective facilities. The analysis was then draughted as a qualitative narrative review. Finally, the review was broken down into an assessment of the hospital's outpatient clinic setting, inpatient department, emergency department and other departments. Results: The survey was conducted at seven public sector hospitals in three major cities of Pakistan. The survey focused on administrative and nonmedical parameters of healthcare facilities. Overall, the hospitals of Lahore and Islamabad lacked mass casualty apparatus and cleanliness, and staff behaviour can be improved. The hospitals in Rawalpindi have mass casualty apparatuses in place. However, they need improvement in accessibility services and hygiene and staff attitude. Conclusions: The survey showed that all the hospitals had good access and accessibility, and the directions were clearly marked for the visitors. The hospital staff is knowledgeable about the hospital, but their behaviour needs to be improved. Also, the quality of the cleanliness and waiting areas is fair but needs improvements. Finally, regular cheques via regular feedback and quality assessments can improve healthcare delivery.

Comparison of nebulised 3% hypertonic saline with ipratropium bromide in treatment of children with bronchiolitis: a randomized control trial.

Introduction: Several drugs are in use for nebulization in children with acute bronchiolitis and no study has yet been conducted to compare the treatment outcome of nebulized ipratropium bromide and nebulized 3% hypertonic saline in Pakistan. Objective: The objective was to compare the treatment outcome of nebulized hypertonic saline and ipratropium bromide in children with acute bronchiolitis. Setting: Department of Pediatrics. Study duration: October 2019 to March 2020. Subjects and methods: A total of one hundred (n=100) children of either sex diagnosed with acute bronchiolitis were enrolled and randomized either to be nebulized with 3% hypertonic saline or ipratropium bromide. Outcomes were assessed in terms of respiratory rate, heart rate, and SpO2 and respiratory distress assessment instrument score at different time intervals, length of hospital stay, and need of admission. Results: Respiratory rate and SPO2 improved significantly at 60 min and 24 h, respiratory distress assessment instrument improved significantly at 30 min, 60 min, and 24 h after the treatment in patients who were nebulized with hypertonic saline when compared to those nebulized with ipratropium bromide. The length of hospital stay was significantly shorter (2.63 vs. 3.82 days, P=0.008) and a lesser number of patients needed hospital admission (22% vs. 44%, P=0.019) in patients who were nebulized with hypertonic saline when compared to those nebulized with ipratropium bromide. Conclusions: Nebulization with 3% hypertonic saline resulted in significant improvement in symptoms, a shorter duration of hospital stay, and a lesser number of hospital admissions as compared to nebulization with ipratropium bromide in children with acute bronchiolitis.

Factors influencing refusal of lumbar puncture in children under age 10: a cross-sectional study.

Background: This study aimed to investigate the factors associated with refusal of lumbar puncture (LP) in children aged 1-10 years who presented to a paediatric department in our hospital. Methods: A sample of parents and guardians of children who presented to the paediatric department were surveyed to gather information about their educational background and decision-making processes. Attending doctors were also interviewed using a questionnaire to gather their perspectives on the reasons for LP refusal in children. Attending doctors then tried to convince the parents or guardians to see if it changed their decision. Results: The study found that the majority of parents and guardians had a lower educational background, with over half being illiterate. Refusal of LP was seen most frequently in parents or guardians who were illiterate. The decision-making process was found to be heavily dependent on the father in a male-dominated society. Peer pressure and lack of knowledge were found to be factors that contributed to LP refusal. Conclusion: Refusal of a LP was linked to having a lower educational background and to societal influences in this cross-sectional study of children aged 1-10 years. More than half of the parents and guardians were illiterate, indicating that they had a lower level of education. Refusing LP was influenced by a number of factors, including social pressure and a lack of information. However, these obstacles were overcome thanks to the efforts of the attending doctors who dispelled myths and reassured the parents and guardians of the necessity and safety of the procedure. Possible roadblocks include a lack of financial resources and common misconceptions about LP. These results highlight the significance of addressing educational and societal factors to enhance children's healthcare.

Patient survival prediction in locally advanced cervical squamous cell carcinoma using MRI-based radiomics: retrospective cohort study.

Cervical cancer is a major health concern for women, ranking as the fourth most common cancer and a significant cause of cancer-related deaths worldwide. To enhance prognostic predictions for locally advanced cervical squamous cell carcinoma, we conducted a study utilizing radiomics features extracted from pretreatment magnetic resonance images. The goal was to predict patient survival and compare the predictive value of these features with clinical traits and the 2018 International Federation of Obstetrics and Gynecology (FIGO) staging system. In our retrospective cohort study, we included 500 patients with confirmed cervical squamous cell carcinoma ranging from FIGO stages IIB to IVA under the 2018 staging system. All patients underwent pelvic MRI with diffusion-weighted imaging before receiving definitive curative concurrent chemoradiotherapy. The results showed that the combination model, incorporating radiomics scores and clinical traits, demonstrated superior predictive accuracy compared to the widely used 2018 FIGO staging system for both progression-free and overall survival. Age was identified as a significant factor influencing survival outcomes. Additionally, primary tumour invasion stage, tumour maximal diameter, and the location of lymph node metastasis were found to be important predictors of progression-free survival, while primary tumour invasion stage and lymph node metastasis position individually affected overall survival. During the follow-up period, a portion of patients experienced disease-related deaths or tumour progression/recurrence in both sets. The radiomics-score significantly enhanced prediction ability, providing valuable insights for guiding personalized therapy approaches and stratifying patients into low-risk and high-risk categories for progression-free and overall survival. In conclusion, our study demonstrated the potential of radiomics features as a valuable addition to existing clinical tools like the FIGO staging system, offering promising advancements in managing locally advanced cervical squamous cell carcinoma.

Novel echocardiographic markers for left ventricular filling pressure prediction in heart failure with preserved ejection fraction (ECHO-PREDICT): a prospective cross-sectional study.

Heart failure with preserved ejection fraction is a complex clinical syndrome associated with a high level of morbidity and mortality, constituting 56% of heart failure cases and showing an increasing prevalence. The E/Ea ratio, used for echocardiographic assessment of left ventricular (LV) filling pressure, has been commonly recommended as a noninvasive measure. However, its validity lacks robust prospective validation in patients with preserved LV ejection fraction, and its accuracy has been questioned in comparison to patients with reduced LV ejection fraction. The objective of this study was to evaluate the accuracy of novel echocardiographic markers incorporating peak E velocity, left atrial volume index (LAVi), and pulmonary artery systolic pressure (PAP) for noninvasive estimation of LV end-diastolic pressure (LVEDP) against invasive measurement. In this cross-sectional study conducted at a tertiary care hospital, a sample size of 122 participants was utilized. Statistical analyses including independent samples t-test, χ2 test, and linear regression analysis were employed to explore correlations and predict outcomes. The results indicated that Group 1 (LVEDP <20 mmHg) had a mean age of 59.25 years, while Group 2 (LVEDP >20 mmHg) had a mean age of 56.93 years. Mitral E velocity positively predicted LVEDP, while Mitral E/A ratio showed a negative association. Notably, (E+PAP)/2, (E+LAVi)/2, and Mitral E exhibited good discriminative ability, with respective area under the curve values of 0.840, 0.900, and 0.854. (E+LAVi)/2 demonstrated the highest discriminatory power, with a threshold of 40.100, yielding high sensitivity (0.971) but relatively low specificity (0.302) in predicting LVEDP greater than 20. These findings emphasize the accuracy and utility of combining diastolic variables and peak E velocity as markers for left ventricular filling pressure in patients with a high burden of cardiac disease. Additionally, the study highlights the importance of these parameters in assessing cardiac abnormalities and supports the potential of novel echocardiographic parameters, particularly (E+LAVi)/2, in predicting LVEDP greater than 20. Further research is warranted to validate and explore the prognostic implications of these parameters in larger patient populations, ultimately improving the diagnosis and management of cardiac disease and enhancing clinical outcomes.

A rare concurrent incidence of adult-onset acute disseminated encephalomyelitis and antiphospholipid antibody syndrome: A case report.

INTRODUCTION: Acute disseminated encephalomyelitis (ADEM) is a demyelinating immune-mediated condition of the central nervous system, whereas antiphospholipid antibody syndrome (APLA) is an autoimmune disorder accompanied by thrombosis and pregnancy-related problems. We present a unique case of a 30-year-old female with ADEM coexisting with APLA, highlighting the importance of early identification and specialized care. PRESENTATION OF CASE: We present a case of a 30-year-old woman with a history of hypertension, multiple miscarriages, and non-compliance with medication, who presented with altered consciousness and weakness in all four limbs. Laboratory tests revealed positive anti-cardiolipin and lupus anticoagulant antibodies, confirming APLA. A neurological examination revealed increased limb tone, heightened reflexes, and extensor plantar responses. MRI revealed confluent white matter lesions that were consistent with ADEM. The patient received prompt treatment with intravenous methylprednisolone and then received oral prednisone, leading to a rapid improvement in neurological status. DISCUSSION: The intricate interaction between ADEM and APLA remains enigmatic. The plausible connection between "molecular mimicry" and weakened blood-brain barrier, substantiated by antiphospholipid antibodies, may help explain their concurrent occurrence. CONCLUSION: This case highlights the significance of early diagnosis and management of the rare and complex coexistence of ADEM and APLA to attain optimal outcomes, as well as the significance of careful examination for simultaneous autoimmune markers in individuals presenting with neurological disturbances.

Lifestyle and Dietary Habits Change Before and During Quarantine and Subsequent Weight Gain.

Background: Pandemics greatly affected human health due to changes in dietary habits and lifestyle. Methods: A multi-centric comparative cross-sectional study was conducted online using a structured questionnaire with 323 respondents from two medical colleges of Lahore, Pakistan. The collected data was analyzed including various variables of dietary habits, lifestyle changes and were compared by using paired sample t-test. Chi-square test was applied to measure the relation of weight gain with lifestyle and dietary habits changes. Result: Out of 323 participants, 64.5% of them observed an increase in their weights and 64.1% of respondents noticed an increase in caloric intake. An increase in chicken, milk, oil, sugar and legumes intake was increased significantly during the quarantine. The lifestyle changes were noted in 91.6% of participants and decreased physical activity, working duration and outdoor games were found significant. Out of 7.4% of students who were smokers, 6.8% of them quit smoking during the quarantine. Conclusion: A significant increase in weight is indicated during quarantine as compared to before quarantine probably due to the changes in dietary habits and lifestyle. If the pandemic prolongs, the problem of weight gain may worsen and lead to obesity and other health problems.

Current challenges and potential solutions to the use of digital health technologies in evidence generation: a narrative review.

Digital health is a field that aims to improve patient care through the use of technology, such as telemedicine, mobile health, electronic health records, and artificial intelligence. The aim of this review is to examine the challenges and potential solutions for the implementation and evaluation of digital health technologies. Digital tools are used across the world in different settings. In Australia, the Digital Health Translation and Implementation Program (DHTI) emphasizes the importance of involving stakeholders and addressing infrastructure and training issues for healthcare workers. The WHO's Global Task Force on Digital Health for TB aims to address tuberculosis through digital health innovations. Digital tools are also used in mental health care, but their effectiveness must be evaluated during development. Oncology supportive care uses digital tools for cancer patient intervention and surveillance, but evaluating their effectiveness can be challenging. In the COVID and post-COVID era, digital health solutions must be evaluated based on their technological maturity and size of deployment, as well as the quality of data they provide. To safely and effectively use digital healthcare technology, it is essential to prioritize evaluation using complex systems and evidence-based medical frameworks. To address the challenges of digital health implementation, it is important to prioritize ethical research addressing issues of user consent and addressing socioeconomic disparities in access and effectiveness. It is also important to consider the impact of digital health on health outcomes and the cost-effectiveness of service delivery.

Lansoprazole plus levosulpiride versus esomeprazole in participants with gastroesophageal reflux disease and erosive esophagitis: a double blinded randomized control trial.

Aim: The aim was to compare the efficacy and safety of lansoprazole plus levosulpiride over esomeprazole. Methodology: This randomized control trial recruited 1000 participants having symptomatic gastroesophageal reflux disease (GERD) and erosive esophagitis and they were blindly randomized into two groups in a 1:1 ratio with appropriate concealment. Group 1 was given lansoprazole plus levosulpiride combination twice daily whereas group 2 was prescribed only esomeprazole twice daily. The primary efficacy endpoint was the healing of erosive esophagitis and GERD at week 49. Secondary assessments included improvement in quality of life. Participants' quality of life was assessed before starting the treatment and post-treatment using a short-form health survey questionnaire (SF-36). Results: The lansoprazole plus levosulpiride group had significantly lower rates of positive postintervention GERD and erosive esophagitis status, and higher rates of sustained resolution of heartburn compared to the esomeprazole alone group. However, the lansoprazole plus levosulpiride group also had a higher risk of nausea. Conclusion: Lansoprazole plus levosulpiride is a more effective and safe treatment for GERD than esomeprazole alone. Participants in the lansoprazole plus levosulpiride group showed a significantly higher rate of sustained resolution of GERD, lower rates of postintervention GERD and erosive esophagitis status, and a higher incidence of nausea compared to the esomeprazole alone group. Although quality of life worsened in both groups, adverse effects did not significantly differ. These findings strongly support the use of lansoprazole plus levosulpiride as a preferred treatment option for GERD and erosive esophagitis, which could have significant clinical implications for managing this common condition.

Diagnostic accuracy of plasma brain natriuretic peptide for evaluation of dyspnea NYHA-III and NYHA-IV in emergency department of tertiary care hospital.

Objective: To determine the diagnostic accuracy of breathing not properly (BNP) for evaluation of dyspnea NYHA III and IV due to systolic heart failure in emergency department patients keeping echocardiography as the gold standard. Study design: Cross-sectional validation study. Setting: Department of Accident and Emergency Duration of Study: 25 July 2022-25 January 2023. Subjects and methods: A total of 115 of both sexes presenting with acute onset of dyspnea and having NYHA Class III and IV were included. Emergency nursing staff had immediately taken a single venous blood sample for BNP and creatinine levels and a 2D echo was performed. Ejection fraction was recorded, and the diagnosis of systolic heart failure on the basis of an ejection fraction, that is less than or equal to 45% was documented. Results: The age range in this study was from 18 to 65 years, with a mean age of 49.147±8.73 years. Mean BNP levels were 139.452±84.04 pg/ml. Patients with NYHA class III was 67.8 and 32.2% belongs to NYHA class IV. BNP levels greater than or equal to 100 pg/ml diagnosed 76 (66.1%) and echocardiography has diagnosed 68 (59.1%) patients with heart failure. BNP levels greater than or equal to 100 pg/ml had shown sensitivity 94.1%, specificity 74.5%, and diagnostic accuracy 86%, positive predictive value 84.21%, negative prediction value 89.74%, likelihood positive ratio 3.68 and likelihood negative ratio was 0.08 in diagnosis of heart failure. Conclusion: BNP estimation is a sensible and particular procedure for diagnosing CHF in patients who present to the emergency department with acute dyspnea and may add extra advantages to the administration of patients with congestive heart failure (CHF) in our population.

Sertraline versus escitalopram in South Asians with moderate to severe major depressive disorder: (SOUTH-DEP) a double-blind, parallel, randomized controlled trial.

Objective: The study design included the double-blind, parallel, randomized controlled trial. The aim of this randomized controlled trial was to compare the efficacy and safety of sertraline and escitalopram in participants with moderate to severe major depressive disorder (MDD). Methods: The study was conducted in South Asian participants. A total of 744 participants with moderate to severe MDD were randomly assigned to receive either sertraline or escitalopram for 8 weeks. Drug dosages and titration schedules were based on the recommendations of the prescribing information for each product and according to the judgment of the clinicians involved in the study. The primary outcome measures were changes from baseline on the Montgomery-Åsberg Depression Rating Scale (MADRS) and the clinical global impression (CGI) scale as well as the frequency of adverse events in both groups. Baseline MADRS scores in the escitalopram and sertraline groups were 28.2±0.47 (mean±SD) and 29.70±0.46 (mean±SD) respectively, and was no variability in the baseline assessments. Changes in MADRS as well as CGI scales at the end of the study were significant only for the sertraline group whereas they remained statistically nonsignificant for the escitalopram group. Results: The results of the study showed that sertraline was more efficacious than escitalopram in reducing depression rating scales such as MADRS and CGI, and that participants subjectively felt better regarding their symptoms in the sertraline group. Sertraline displays enhanced safety or tolerability than other groups of antidepressants, which frequently cause high levels of drowsiness, dizziness, blurred vision, and other undesirable effects. Adverse events were seen in both groups, but delayed ejaculation was the most frequent adverse event seen in both groups. However, a greater number of participants reported having nausea and insomnia in the sertraline group compared to the escitalopram group. Conclusion: Our study clearly highlights that there is a statistically significant difference in efficacy between sertraline and escitalopram at the doses used in our study. Sertraline was able to significantly lower the depression rating scales like MADRS and CGI in participants with moderate to severe MDD. Participants subjectively felt better regarding their symptoms in the sertraline group. The most frequent adverse event in both groups was delayed ejaculation. From an efficacy standpoint, sertraline was more efficacious than escitalopram. The study indicates that the prevalence of depressive disorders in South Asia is comparable to the global estimate, and Bangladesh and India has higher proportions of people with depressive disorders in South Asia. Additionally, females and older adults (75-79 years) have the highest burden of depressive disorders across all countries in the region. This study's limitation included the absence of a placebo arm. An additional limitation of the current study was the lack of an evaluation of inter-rater reliability and the research sample could not have been uniform in terms of the kind of depressive disorders and bipolarity.

Use of National Institute for Health and Care Excellence head injury guidelines among patients with delayed presentation after head trauma can lead to missed traumatic brain injury: a 5-year institutional review.

Introduction: In 2014, traumatic brain injury (TBI) caused 3 million ER visits, hospitalizations, and deaths in the US. The National Institute for Health and Care Excellence (NICE) guidelines, initially generated using data from patients presenting within 24 h of head trauma, are used to determine the need for head computed tomography (CT) scan in patients after 24 h. The authors wanted to determine the proportion of CT scans for head trauma performed at our center in late presenters (>24 h after head trauma), the incidence of intracranial pathology in early (24 h) versus late (>24 h) presenters, and the sensitivity of the NICE guidelines for TBI in these two subpopulations. Methods: A retrospective chart review was conducted at a tertiary care center in Karachi. All people (>16) who had a head CT for head trauma from 2010 to 2015 were included. Age, sex, primary diagnosis, comorbid disorders, mechanism-of-injury, duration (in hours) from head trauma to presentation, site, and extent of injury (injury severity scale), hospital stay, number and details of surgical procedures, CT scan findings, other injuries, and mortality were recorded. Means were compared using the Independent Sample t-test, while categorical variables were compared using χ2. Multivariate logistic regression analyses were used to identify TBI predictors. Results: The authors found 2009 eligible patients; seven were excluded due to incomplete medical records. The final statistical analysis comprised 2002 head trauma patients. Overall, 52% of early and late presenters had severe injuries, and 2.3% died. 32.2% of patients with head trauma had CT after 24 h. Early presenters were 46.7% traumatized, while late presenters were 63%. The NICE guidelines were 93% sensitive for early presenters and 83% for late presenters with traumatic intracranial injury. Conclusion: Patients coming to the emergency department after 24 h of head trauma are a large proportion of the overall head trauma population. The NICE guidelines for late-presenting head injuries are less sensitive and may overlook intracranial injuries if imaging is not performed.
