The clinical and economic burden of percutaneous coronary intervention (PCI) in young adults (18-45 years) is understudied. We used the National Inpatient Sample database between 2004 and 2018 to study trends in PCI volume, in-hospital mortality, length of stay (LOS), and health care expenditure among adults aged 18 to 44 years who underwent PCI. The data were weighted to explore national estimates of the entire US hospitalized population. We identified 558,611 PCI cases, equivalent to 31.4 per 1,000,000 person-years; 25.4% were women, and 69.5% were White adults. Overall, annual PCI volume significantly decreased from 41.6 per 100,000 in 2004 to 21.9 per 100,000 in 2018, mainly due to 83% volume reduction in non-myocardial infarction (MI) cases. The prevalence of cardiometabolic comorbidities, smoking, and drug abuse increased. Overall, in-hospital mortality was 0.87%; women had higher mortality than men (1.12% vs 0.78%; P = 0.01). The crude and risk-adjusted in-hospital mortality significantly increased between 2004 and 2018. Women, STEMI, NSTEMI, drug abuse, heart failure, peripheral vascular disease, and renal failure were associated with higher odds of in-hospital mortality. Inflation-adjusted cost significantly increased over time ($21,567 to $24,173). We noted reduction in PCI volumes but increasing mortality and clinical comorbidities among young patients undergoing PCI. Demographic disparities existed with women having higher in-hospital mortality than men.Hypertension (HTN) is one of the most important public health challenges, especially in developing countries. Despite individual studies, information on the exact prevalence of prehypertension (pre-HTN) and HTN in the Middle East and North Africa is lacking. This meta-analysis was conducted to evaluate prevalence of pre-HTN and HTN, awareness, treatment, and control in the Middle East and North Africa region. PubMed, Web of Science, and Scopus databases were searched from inception to April 30, 2021. Keywords included hypertension, pre-hypertension, awareness, treatment, and control. The quality of the included studies was evaluated using the Hoy scale. A random-effects model was evaluated based on overall HTN. The heterogeneity of the preliminary studies was evaluated using the I2 test. A total of 147 studies involving 1,312,244 participants were included in the meta-analysis. Based on the results of the random-effects method (95% CI), the prevalence of pre-HTN and HTN were 30.6% (95% CI 25.2, 36.0%; I2 = 99.9%), and 26.2% (95% CI 24.6, 27.9%; I2 = 99.8%), respectively. The prevalence of HTN awareness was 51.3% (95% CI 47.7, 54.8; I2 = 99.0%). The prevalence of HTN treatment was 47.0% (95% CI 34.8, 59.2; I2 = 99.9%). The prevalence of HTN control among treated patients was 43.1% (95% CI 38.3, 47.9; I2 = 99.3%). Considering the high prevalence of HTN, very low awareness, and poor HTN control in the region, more attention should be paid to preventive programs for HTN reduction.Severe coronary artery calcification (CAC) is associated with high rate of procedural complications. The current techniques that facilitate percutaneous coronary interventions in moderate to severe CAC have significant risk of complications, including periprocedural myocardial infarction , dissection, perforation and transient atrioventricular block. Coronary Intravascular lithotripsy (IVL) is a novel technology for the treatment of moderate to severe calcified lesions. IVL uses sonic pressure waves to break down the calcium deposits with no to minimal impact on the blood vessel tissues, which makes IVL a safe option with high procedural success and minimal complications. Here, we discuss coronary IVL as a treatment option for CAC and summarize the major clinical trials performed evaluating the safety and outcome of IVL.
Dexamethasone as adjunct to local anesthetic solution improves the quality of brachial plexus block (BPB). However, evidence for its efficacy at low doses (< 4 mg) is lacking. This study was designed to evaluate the duration of analgesia attained with low dose dexamethasone as adjuvant to local anesthetic for creation of arteriovenous fistula (AVF) under BPB.

Sixty-six patients scheduled for AVF creation were randomly allocated to receive either saline (control) or 2 mg dexamethasone, together with 0.5% ropivacaine and 0.2% lignocaine. The primary outcome was duration of analgesia, defined as time from performing the block to the first analgesic request. The secondary outcomes were time from injection to complete sensory block, time from injection to complete motor block, duration of motor block, postoperative analgesic consumption, and fistula patency at three months.

All the blocks were effective. In the group that received dexamethasone, the time to first analgesic request was significantly delayed (432 ± 43.8 minutes vs. 386.4 ± 40.2 minutes; p < 0.01). The onset of sensory and motor blockade occurred faster in dexamethasone group and overall analgesic consumption was also reduced. However, dexamethasone addition did not prolong the duration of motor block. There was no statistically significant difference in the patency of fistulas between the two groups at three months. (p=0.34).

Addition of low-dose perineural dexamethasone to local anesthetic solution significantly prolonged the duration of analgesia. Further trials are warranted to compare the adverse effects between dexamethasone doses of 4 mg and lower.

Emergence Delirium (ED) is a combination of disturbance of perception and psychomotor agitation that is common in pediatric patients after general anesthesia, especially at preschool age. Since the effect of ED on the length of stay has been studied in adults but infrequently in children, the aim of this study was to investigate the relationship between ED and length of stay in this population.

A single center, retrospective, observational study was carried out in children who underwent tonsillectomy or adenotonsillectomy. The Pediatric Anesthesia Emergence Delirium (PAED) scale was used to assess ED. In addition to the time to hospital discharge (time frame 24 hours), drugs used, comorbidities, early postoperative complications, and pain were investigated if potentially associated with the complication.

Four hundred sixteen children aged from 1.5 to 10 years (183 female, 233 male) were included. ED occurred in 25.5% of patients (n=106). Patients were divided into the ED group and the No-ED group. The discharge time was similar in both groups. ALC-0159 No significant differences were observed in the frequency of postoperative complications. The use of fentanyl or dexmedetomidine did not affect ED occurrence. The frequency of pain was greater in the ED group, both in the recovery room and in the ward (p=0.01).

The occurrence of ED in children after tonsillectomy/adenotonsillectomy did not extend the length of stay.

Occasionally, these patients exhibit cardiac and respiratory functions so severely compromised they cannot tolerate lying in the supine position, not even for the time required to insert a central venous catheter. The authors describe three cases of successful ultrasound-guided internal jugular vein cannulation in prone position. The alternative approach here described enables greater safety and well-being for the patient, reduces the number of episodes of decompensation, and risk of tracheal extubation and loss of in-situ vascular lines.
Awake fiberoptic tracheal intubation is an established method of securing difficult airways, but there are some reservations about its use because many practitioners find it technically complicated, time-consuming, and unpleasant for patients. Our main goal was to test the safety and efficacy of a 300-mm working length fiberscope (video rhino-laryngoscope) when used for awake nasotracheal intubation in difficult airway cases.

This was a prospective, single-center study involving adult patients, having an ASA physical status between I and IV, with laryngopharyngeal pathology causing distorted airway anatomy. Awake nasotracheal intubation, using topical anesthesia and light sedation, was performed using a 300 mm long and 2.9 mm diameter fiberscope equipped with a lubricated reinforced endotracheal tube. The primary outcomes were the success and duration of the procedure. Patients' periprocedural satisfaction and other incidents were recorded.

We successfully intubated all 25 patients included in this study. The mean ±SD duration of the procedure, starting from the passage of the intubating tube through one of the nostrils until the endotracheal intubation, was 76 ± 36 seconds. Most of the patients showed no discomfort during the procedure with statistical significance between the No reaction Group with the Slight grimacing Group (95%CI 0.13, 0.53, p=0.047) and the Heavy grimacing Group (95%CI 0.05, 0.83, p=0.003). The mean ±SD satisfaction score 24 hours post-intervention was 1.8 ± 0.86 - mild discomfort. No significant incidents occurred.

Our study showed that a 300-mm working length flexible endoscope is fast, safe, and well-tolerated for nasotracheal awake intubation under challenging airways.

The pathophysiology of childhood food allergy (FA) and its natural history are poorly understood. Clarification of the underlying mechanism may help identify novel biomarkers and strategies for clinical intervention in children with FA.

This study aimed to identify metabolites associated with the development and resolution of FA.

The metabolomic profiles of 20 children with FA and 20 healthy controls were assessed by liquid chromatography-tandem mass spectrometry. Comparative analysis was performed to identify metabolites associated with FA and FA resolution. For subjects with FA, serum samples were collected at the time of diagnosis and after resolution to identify the changes in metabolite levels. The selected metabolites were then quantified in a quantification cohort to validate the results. Finally, genome-wide association analysis of the metabolite levels was performed.

The study demonstrated a significantly higher level of sphingolipid metabolites and a lower level of acylcarnitine metabolites in children with FA than those in healthy controls. At diagnosis, subjects with resolving FA had a significantly high level of omega-3 metabolites and a low level of platelet-activating factors compared to persistent FA. However, the level of omega-3 metabolites decreased in children with resolving FA but increased in children with persistent FA during the same time. The quantification data of omega-3-derived resolvins, platelet-activating factor, and platelet-activating factor acetylhydrolase activity further supported these results.

The lipid metabolite profile is closely related to childhood FA and FA resolution. This study suggests potential predictive biomarkers and provides insight into the mechanisms underlying childhood FA.
