The impact of cognitive impairment in patients with acute coronary syndrome undergoing percutaneous revascularization: a systematic review and meta-analysis.

BACKGROUND: Cognitive impairment has been known to be associated with negative health impacts. Several studies recently demonstrated inconsistent outcomes among cognitive impaired patients with acute coronary syndrome (ACS). Our study aimed to determine the impact of cognitive impairment for patients with ACS. METHODS: Databases were searched through October 2020. Studies reporting revascularization rates, short- and long-term mortality among ACS patients with cognitive impairment were included. Effect estimates from the individual studies were extracted and combined using random effect and generic inverse variance method of DerSimonian and Laird. RESULTS: In total, 11 observational studies were included in the analysis consisting of 810 122 ACS patients, with 3.5% cognitive impairment patients. Our analysis suggested that cognitive impairment was associated with a lower rate of percutaneous coronary intervention (PCI) [odds ratio (OR), 0.63; 95% confidence interval (CI), 0.42-0.96; I2 = 98.5%; P = 0.033]. Among patients undergoing PCI, cognitive impairment was statistically associated with increased 30-day mortality (OR, 1.34; 95% CI, 1.14-1.57; I2 = 83.1%; P < 0.001) and long-term mortality (OR, 1.80; 95% CI, 1.04-3.11; I2 = 36.3%; P = 0.034). CONCLUSION: Our study demonstrated that cognitive impairment was not only associated with lower rates of percutaneous revascularization but also with increased 30-day and long-term mortality.

Management of ST Elevation Myocardial Infarction (STEMI) in Different Settings.

ST-segment elevation myocardial infarction (STEMI) is a life-threatening condition that requires emergent, complex, well-coordinated treatment. Although the primary goal of treatment is simple to describe-reperfusion as quickly as possible-the management process is complicated and is affected by multiple factors including location, patient, and practitioner characteristics. Hence, this narrative review will discuss the recommended management and treatment strategies of STEMI in the circumstances.

Use of Unique Doppler Flow-Pattern for the Diagnosis of Left Ventricular Diverticulum.

Isolated congenital left ventricular diverticulum (LV) is reportedly a rare finding. It is frequently associated with other congenital defects involving heart, pericardium, sternum, diaphragm, and abdominal wall. It is an outpouching from the ventricle and has all three layers of left ventricular free walls. We present the case of a 53-year-old woman who was discovered to have an outpouching of the LV apex on a nongated chest CT scan raising possibility of a pseudoaneurysm. A transesophageal echocardiogram (TEE) showed systolic diminution of this outpouching with unique Doppler flow-patterns suggesting a diagnosis of a muscular type of LV diverticulum instead of a postinfarct LV pseudoaneurysm. The patient was reassured and treated conservatively.

Reaching the goal of Universal Salt Iodization (USI): experience of Uttar Pradesh, India.

BACKGROUND: In 2002, the percentage of households consuming iodized salt in the state of Uttar Pradesh (UP) in India dropped to as low as 6%. This implied that 3.5 million newborns in this non-salt producing state, with 180 million population, were at risk of brain damage unless universal accessibility and consumption of iodized salt was ensured and sustained. OBJECTIVES: Urgent measures were introduced in 3 phases in the statefor accelerating procurement, distribution and consumption of iodized salt. METHODS: In the first phase, a study on mapping of salt wholesalers and understanding the salt trading system--including understanding the knowledge, attitudes, and practices of salt traders was undertaken to accelerate efforts to influence availability, marketing, and accessibility of iodized salt. The study revealed that a total of only 344 primary wholesalers supplied salt to the entire state. Of these, 126 wholesalers marketed 80% of salt and were located in only 15 of the total 70 districts of the state. This finding became a very strong basis for the program in phase II, which focused on the critical group of wholesalers and set up a system to frequently interact with them. The salt wholesalers were equipped with Salt Testing Kits (STKs) to ensure adequate iodine content in the salt procured by them and adherence to the legal ban on the sale of non-iodized salt for human consumption. Simultaneously, a "child-to-community" approach was launched through involvement of middle and high school children to create demand and monitor consumption of iodized salt at the household level. Over 217,000 salt samples (about 26,000 samples per quarter) were brought in by school children and tested for iodine content. RESULTS: The school activities resulted not only in influencing consumption of iodized salt, but also galvanized the entire chain linking consumers, retailers, and wholesalers. In less than 2 years, salt procured with nil iodine decreased from 38% to 15.3%, and salt marketed with adequate iodine level increased from 28.6% to 64.9%. School data revealed an increase in consumption of iodized salt from 6% to 46.7%. In phase 3, additional standardized activities at the school level were included and the program was taken to scale in the state. CONCLUSION: The findings revealed that identification and inclusion of salt wholesalers-not only the salt manufacturers-was important for achieving a rapid positive shift in iodized salt marketing and consumption practices.
