Postoperative atrial fibrillation (POAF) refers to new-onset atrial fibrillation (AF) that develops after surgery and is associated with an increased risk of mortality and thromboembolic events. The optimal management and treatment methods for POAF complications are not yet fully established. This systematic review aimed to evaluate the various treatment and management approaches currently available in terms of their suitability, efficacy, and side effects in handling POAF incidence post-surgery. Google Scholar and PubMed electronic databases were searched extensively for relevant articles examining the various management techniques currently used to manage POAF and published between 2018 and 2023. Data were collected on the type of surgery the patients underwent, POAF definition period, intervention, and outcome of interest. Following a systematic assessment guided by the inclusion criteria, 10 of the 579 studies retrieved were included in this study, and 293,417 POAF cases were recorded. Three of these studies used different rhythm control and rate control treatments to manage POAF cases, while seven studies used various anticoagulation therapies to manage POAF incidence. For asymptomatic patients within one to three days of surgery, rate control is sufficient to manage POAF, and routine rhythm control is not needed; rhythm control should be reserved for patients who develop complications such as hemodynamic instability. Anticoagulation was performed in patients whose POAF exceeded four days after surgery. Anticoagulation was associated with an increased risk of mortality, stroke, thromboembolic events, and major bleeding in patients who underwent coronary artery bypass graft (CABG) surgery. In contrast, in a few other studies, anticoagulation treatment led to improved outcomes in patients who developed POAF. A wide range of management methods are available for POAF after different types of surgery. However, there is only limited evidence to guide the clinical practice. The data available are mainly retrospective and insufficient to accurately evaluate the efficacy of the various management methods available for POAF. Future research should make efforts to standardize the treatment for this condition.

Electrolyte disorders in alcohol-dependent patients can be due to a multitude of reasons. We discuss a patient with diabetes mellitus, seizure disorder, and alcoholism who presented with seizure episodes and vomiting following a binge alcohol intake. The evaluation showed life-threatening metabolic derangements that included hyponatremia, hypokalemia, hypomagnesemia, hypocalcemia, hypochloremia, hypophosphatemia with elevated blood glucose, and metabolic alkalosis with a normal anion gap. Subsequently, a detailed urinary analysis revealed a urinary loss of electrolytes. We emphasize that alcohol-induced tubular injury is a possibility when such a clinical presentation is seen in the emergency room. The complex interplay of various electrolytes in homeostasis posed a great challenge in the management of this patient. Our case reiterates this intricate electrolyte correction policy.

The paucity of large-scale data exploring the effect of prior bariatric surgery on recurrent stroke outcomes in older individuals with obesity who survived a stroke led us to address the gap, with an emphasis on the risk of recurrent stroke and its trends. Retrospective analysis of the National Inpatient Sample data from 2016 to 2019. Older individuals with obesity who survived a stroke (>65 years) and had a recurrent acute ischemic stroke (AIS) hospitalization, with or without prior bariatric surgery (PBS), were identified using ICD-10 codes. Recurrent stroke trends, demographic characteristics, and comorbidities between the cohorts were compared. Analyzing 643,505 older individuals with obesity who survived a stroke, we identified that 11,820 had undergone PBS. Both groups (no PBS vs. PBS) were predominantly female (59.7 % vs. 73.7 %), identified as white (76.5 % vs. 83.8 %), and covered by Medicare (91.7 % vs. 90.7 %). Diabetes, hyperlipidemia, prior myocardial infarction, and peripheral vascular diseases were more common in those without PBS. In contrast, tobacco use disorder, drug abuse, and valvular diseases were more common in those with PBS. There was no significant difference in the prevalence of hypertension between groups.Between 2016 and 2019, recurrent AIS hospitalizations were less frequent in the PBS group (4 %-2.9 %, p = 0.035) while remaining stable in the other group (4.4 %-4.2 %, p = 0.064). The risk of recurrent AIS hospitalization was less frequent in the PBS cohort (aOR: 0.77, 95 % CI: 0.60-0.98). PBS in older individuals with obesity who survived a stroke was associated with a 23 % lower risk of recurrent AIS hospitalization with a decreasing trend of prevalence since 2016. These findings could influence clinical practice and contribute to developing secondary prevention strategies for recurrent stroke among these patients.
