Liver function tests as predictors of common bile duct stones in acute cholecystitis patients with a chronic history: A retrospective cohort study on the ACS-NSQIP database.

ABSTRACT: Liver function tests (LFTs) use for common bile duct stone (CBDS) prediction in acute cholecystitis (AC) patients is challenging, especially in patients with chronic cholecystitis (CC) history.This study aims to describe characteristics of AC patients with CC history and assess LFTs' utility for CBDS prediction in these patients.A retrospective cohort study was conducted on adults with a diagnosis of AC and CC history included in the National Surgical Quality Improvement Program database from 2008 to 2016. Patients were categorized into CBDS- (without CBDS) and CBDS+ (with CBDS). Multivariate logistic regression was used to determine CBDS predictors.This study included 7458 patients, of which 40.2% were CBDS+. CBDS+ patients were more commonly females (64.4% vs 54.7%, P < .001). Mean levels of bilirubin (1.70 vs 0.90, P < .001), SGOT (105.9 vs 49.0, P < .001) and ALP (164.6 vs 103.8, P < .001) were significantly higher among CBDS+ patients.Significant positive predictors of CBDS were female gender, increased BMI, and abnormal bilirubin, ALP and SGOT. AC patients with CC history are more likely to have CBDS. Abnormal LFTs are significantly associated with CBDS in this patient population. Familiarity with these findings can help raise clinical suspicion of providers for earlier evaluation and management of CBDS.

Comparison of outcomes in ST-elevation myocardial infarction according to age.

BACKGROUND: Myocardial infarction constitutes a significant cause of morbidity and mortality. Its pathophysiology varies according to age; atherosclerosis is the most common cause in older patients while thrombosis or plaque rupture is behind premature MI. OBJECTIVE: To compare the outcome differences between young (age ≤ 45 years) and older adults (age > 45 years) presenting with STEMI. METHOD: This was a retrospective cohort study of patients presenting with STEMI to the Emergency Department of a tertiary care center, between 2008 and 2018.Cases were patients age ≤ 45 and controls were the older population. Descriptive and bivariate analyses were conducted followed by Logistic regression to identify the outcomes. RESULTS: 107 cases were matched with 214 controls. Majority of patients were males (93% of cases and controls). Younger patients were more likely to be smokers (80% vs. 57%, p < 0.001) and with a family history of MI (56% vs. 37%, p = 0.002). Diabetes, hypertension, dyslipidemia and a previous history of MI were more common among controls, 37%, 60%, 43% and 42% respectively versus 10%, 24%, 36% and 25% in the younger population. Younger patients had a higher prevalence of single-vessel disease compared to older patients (73% vs. 50%, p = 0.001). LAD was the most commonly blocked vessel in both groups (71% vs. 64% respectively). Ejection fraction was within normal range in the majority of controls and cases (63% vs. 56% respectively and 57% vs. 60% respectively). CONCLUSION: Premature MI predominantly affects males and the associated risk factors are smoking and family history of MI. It's characterized by single-vessel disease as compared to older patients.

The Prevalence of Dysphonia and Dysphagia Symptoms in Patients on Statin Therapy.

OBJECTIVE: To investigate the effect of statin therapy on swallowing and phonation. METHODS: A group of patients on statin therapy and another group not on statins (controls) presenting to the endocrinology clinic between January 2018 and April 2018 were asked to participate. All patients filled Voice Handicap Index (VHI-10), Eating Assessment Tool (EAT-10), and Likert scales for vocal fatigue and hoarseness. Demographic data included age, gender, allergy, and history of smoking. RESULTS: A total of 160 patients were recruited, 75 patients on statin therapy and 85 not on statin therapy. The mean age of the study group was 55.00 years, whereas that of the control group was 45.70 years. The mean duration of statin treatment was 74.92 months. The mean VHI-10 and EAT-10 scores were significantly higher in the statin group compared to the control group (P < 0.05). Although there was no significant difference in the mean Likert scale for vocal fatigue, the mean Likert scale for hoarseness was significantly higher in the statin group compared to the control group (P < 0.05). CONCLUSION: This investigation revealed a significantly higher prevalence of laryngopharyngeal symptoms in patients on statin therapy versus a control group.

Prevalence of MTD among Patients with Functional Dysphagia.

OBJECTIVE: To assess the prevalence of laryngeal muscle tension patterns among patients with functional dysphagia. STUDY DESIGN: Retrospective study. SETTING: The study took place at a university medical center. MATERIAL AND METHODS: The medical charts and laryngeal video recordings were reviewed for all patients who presented with dysphagia and who were referred for barium swallow between 2012 and 2017. A total of 170 cases were identified. Only those with normal findings on barium swallow and the absence of vocal fold pathology (exudative lesions, masses or tumors, paresis, and paralysis), referred to as functional dysphagia, were included in this study. Information retrieved included swallowing and phonatory symptoms in addition to patterns of laryngeal muscle tension. RESULTS: The mean ± SD age of the total group was 41.90 ± 15.10 years with a male:female ratio of 4:1. Seventy-five percent had evidence of at least 1 type of laryngeal muscle tension pattern. The most common pattern was type III, characterized by supraglottic anteroposterior compression (13 of 20), followed by type II, characterized by medial compression of the false vocal folds (5 of 20); only 1 patient had muscle tension pattern type IV, characterized as sphincter-like closure of supraglottic structures. The most common laryngopharyngeal symptom was throat discomfort when swallowing (35%), followed by throat clearing and choking/coughing when eating and drinking (25%). CONCLUSION: The high prevalence of laryngeal muscle tension pattern among patients with functional dysphagia supports the notion that laryngeal tension may be one of the underlying causes of dysphagia.
