Background/Objectives: Sodium glucose co-transporter 2 inhibitors (SGLT2is) have demonstrated a reduction in heart failure (HF) hospitalizations in HF patients and decreased recurrence of atrial fibrillation (AF), including in those who have undergone catheter ablation (CA). The effects of SGLT2i are likely due to suppression of the renin–angiotensin–aldosterone system, reduction in oxidative stress with subsequent improvement in myocardial efficiency, and attenuation of cardiac remodeling. We aim to present the effects of SGLT2i on AF recurrence in patients who have undergone CA for AF. Methods: This is a systematic review and meta-analysis of randomized controlled trials (RCTs) and retrospective studies evaluating the effect of SGLT2i on AF recurrence following CA compared with non-SGLT2i. The primary outcome was the recurrence of AF by the final follow-up reported in each study. Secondary outcomes include AF recurrence by the first follow-up within 12 to 24 months and follow-up intervals (6, 12, 18, 24, and 36 to 42 months) post-ablation, multivariate risk of AF recurrence, and the effect on left atrial diameter (LAD) (less than 45 mm vs. greater than or equal to 45 mm). For risk of bias (ROB) analysis, the NIH ROB and Cochrane ROB2 tool were used. All statistical, heterogeneity, and sensitivity analyses were conducted using Cochrane Review Manager. A random-effect model was employed for all pooled statistical analyses. Results: A total of nine studies, two RCTs and seven retrospective studies, were included (N = 6874) for the primary outcome. Compared to non-SGLT2i (N = 3693), SGLT2i (N = 3181) significantly decreased AF recurrence by the final follow-up (OR = 0.62; 95% CI: 0.45–0.85; p = 0.008). For secondary outcomes, SGLT2i significantly reduced AF recurrence by the first follow-up within 12 to 24 months post-ablation (OR = 0.58; p = 0.0001) and by the different follow-up periods, 6-month (OR = 0.53; p = 0.02), 12-month (OR = 0.56; p = 0.0001), 18-month (OR = 0.55; p = 0.01), and 24-month (OR = 0.60; p = 0.12) follow-up periods. On the other hand, by 36 to 42 months, SGLT2i was associated with increased risk of AF recurrence (OR = 1.41; p = 0.004). Conclusions: We conclude that SGLT2i demonstrated a reduction in AF recurrence following CA, particularly by 12 to 18 months post-ablation.

ABSTRACT Background and Aims Out‐of‐hospital cardiac arrest stands as the primary cause of worldwide mortality. Therefore, all healthcare workers must comprehensively understand and practically apply cardiopulmonary resuscitation (CPR). To address the paucity of literature on this subject, we conducted a nationwide survey among healthcare professionals in Pakistan. Methods This nationwide cross‐sectional study was based on an online questionnaire. The sample pool comprised healthcare professionals and medical students from all over Pakistan. The survey comprised 18 questions aimed to assess the comprehension of CPR, determine the source of their basic life support (BLS) training, and evaluate their competence in performing CPR in real‐life situations. Results The sample size consisted of 951 participants from Pakistan. A total of 712 responders (75%) reported having received CPR or CPR with an Automated External Defibrillator (AED) course, and the same percentage reported that their respective universities had organized the course. The responders reported that the BLS course was made mandatory in only 60% of cases. Most of the respondents were first‐year medical students (21%) and postgraduates (21%). Most of the respondents (78%) professed that the courses had been theoretical as well as practical, and 66% felt confident enacting CPR in out‐of‐hospital settings. Overall, no province was able to achieve a score of greater than 50% when assessed about their knowledge regarding cardiac arrest and CPR. Conclusion This study provides a detailed insight into Pakistan healthcare workers' CPR knowledge and perceptions belonging to different provinces, institutes, designations, and specialties. The participants reported being confident in performing CPR but demonstrated gaps when assessed regarding the revised guidelines and their performance in different scenarios. There is room for further research in overcoming the language barriers and other discrepancies faced by this study.

Key Clinical MessageStone heart syndrome has a complex interaction with digoxin toxicity, where, theoretically, the administration of intravenous calcium can worsen a patient's condition. Research on this subject is conflicting, so it is imperative to approach it cautiously.

Blood transfusion is a common therapeutic intervention in hospitalized patients. There are numerous indications for transfusion, including anemia and coagulopathy with deficiency of single or multiple coagulation components such as platelets or coagulation factors. Nevertheless, the practice of transfusion in critically ill patients has been controversial mainly due to a lack of evidence and the need to consider the appropriate clinical context for transfusion. Further, transfusion carries many risk factors that must be balanced with benefits. Therefore, transfusion practice in ICU patients has constantly evolved, and we endeavor to present a contemporary review of transfusion practices in this population guided by clinical trials and expert guidelines.

Background: Electrocardiogram (EKG) is a commonly used diagnostic tool for the evaluation of the electrical activity of the heart. The purpose of this study was to assess the knowledge and interpretation proficiency of EKG among healthcare professionals (HCPs) in Pakistan. Methods: This prospective cross-sectional study was conducted among HCPs working in different healthcare settings. A structured questionnaire was used to assess the participants’ theoretical knowledge and ability to interpret EKG findings. The data were analyzed using descriptive statistics and χ2 tests. The study indicates that EKG knowledge and interpretation proficiency among HCPs in Pakistan is unsatisfactory. The inadequacy of training periods of EKG training sessions and insufficient participation of HCPs in offered training opportunities put forward the need for the formation and introduction of better structured and efficient EKG training programmes. Results: A total of 511 HCPs participated in the study, 28% of whom reportedly had received formal training for EKG interpretation. About 80% of the participants correctly identified theoretical questions pertaining to EKG, while 58% of the participants were able to accurately interpret EKG findings, and most HCPs (69.9%) read fewer than ten EKGs per week. Conclusion: This study demonstrates a lack of expertise and a poor understanding of EKG in HCPs of Pakistan. The low level of EKG knowledge and interpretation proficiency among HCPs may lead to diagnostic errors and poor patient outcomes. Therefore, efforts should be made to improve EKG education and training among HCPs in Pakistan.

AbstractIntroductionDown syndrome (DS) is associated with multiple comorbid conditions and chronic immune dysfunction. Persons with DS who contract COVID‐19 are at high risk for complications and have a poor prognosis. We aimed to study the clinical symptoms, laboratory and biochemical profiles, radiologic findings, treatment, and outcomes of patients with DS and COVID‐19.MethodWe systematically searched PubMed, MEDLINE, Web of Science, Scopus, and the Cochrane Library using the keywords COVID‐19 or coronavirus or SARS‐CoV‐2 and DS or trisomy 21. Seventeen articles were identified: eight case reports and nine case series published from December 2019 through March 2022, with a total of 55 cases.ResultsPatients averaged 24.8 years (26 days to 60 years); 29 of the patients were male. The most common symptoms were fever, dyspnea, and cough. Gastrointestinal and upper respiratory tract symptoms were commonly reported for pediatric patients. The most common comorbidities present in patients with DS were obesity (49.0%), hypothyroidism (21.6%) and obstructive sleep apnea (15.6%). The patients were hospitalized for a mean of 14.8 days. When the patients were compared with the general COVID‐19 population, the mean number of hospitalized days was higher. Most patients had leukopenia, lymphopenia, and elevated inflammatory markers (d‐dimer and C‐reactive protein). Bilateral infiltrations and bilateral ground‐glass opacifications were frequently seen in chest radiographs and chest computed tomographic imaging. Most of the patients were treated with methylprednisolone, macrolides, and hydroxychloroquine. Of the 55 patients, 22 died. The mean age of the patients who died was 42.8 years. Mortality rate was higher in individuals with DS over 40 years of age.ConclusionMore studies are needed to better understand COVID‐19 infections among persons with DS. In addition, the study was limited by a lack of statistical analyses and a specific comparison group.

Background and objectives: Non-alcoholic fatty liver disease (NAFLD) is characterized by ectopic deposition of fat in the liver, in the absence of other secondary causes of fat buildup. The relationship between NAFLD, including alanine aminotransferase (ALT), and glycated haemoglobin (HbA1c), is important for predicting the severity of disease and prognosis. This study aims to investigate the association of HbA1c in type 2 diabetes mellitus (T2DM) patients with NAFLD via measuring the ALT levels. Materials and methods: This retrospective cross-sectional study enroled 130 patients with T2DM and NAFLD. The association between levels of HbA1c and ALT in patients of NAFLD with controlled and uncontrolled T2DM, respectively, was investigated. Stratification was done based on gender and diabetic control, using HbA1c levels as a marker of glycemic control. Serum ALT levels were also compared in both groups. Results: The mean age of the participants was 50.2±5.7 years. The total participants were 130, of which 77 (59.3%) were females and 53 (40.7%) were males. The numbers of patients having uncontrolled T2DM (HbA1c>7%), and controlled T2DM (HbA1c <7%) were 78 (60%) and 52 (40%), respectively. Moreover, 46 (35.3%) females and 32 (24.7%) males had uncontrolled T2DM, and 31 (23.8%) females and 21 (16.2%) males had controlled T2DM. The mean ALT level for uncontrolled and controlled T2DM in female patients was found to be 24.6±3.4 and 13.5±2.4, respectively, (P <0.05). For male patients, it was found to be 54.0±4.9 and 29.1±5.4, respectively (P=0.008). Conclusion: There is a positive association between elevated HbA1c and ALT levels in T2DM patients with NAFLD.

Key Clinical MessageThis case highlights the need for tailored strategies to address issues like brain herniation, subdural hygroma, and cerebrospinal fluid leak, which, if not managed promptly, can lead to long‐term neurological deficits. Additionally, the role of specialized facilities in delivering highly specialized care for managing such intricate cases cannot be understated.AbstractDecompressive craniectomy‐induced subdural hygroma (SDH) frequently coexists with external cerebral herniation, resulting in neurological impairments. The incidence of brain herniation through a craniectomy defect postoperatively is 25%. Brain herniation (BH), SDH, and cerebrospinal fluid leak require urgent neurosurgical management as they can lead to irreversible long‐term neurological deficits. We report a case of a 42‐year‐old male who presented with headache and grand mal seizures. He was diagnosed with herniation of brain parenchyma through the surgical defect with a displacement of the bone flap by a heterogeneously enhancing lesion in the left parietal lobe along with SDH in the left frontoparietal region post partial resection of high‐grade glioma. In this report, we discuss the pathogenesis and management strategies of brain herniation, wound infection, cerebrospinal fluid (CSF) leak, ipsilateral SDH, floating bone flap, and communicating hydrocephalus in an adult patient following partial resection of high‐grade glioma. This particular case emphasizes the value of an individualized patient‐centered surgical approach to minimize the risk of postoperative complications.
