RESUMO
BACKGROUND: The prognosis of idiopathic pulmonary fibrosis (IPF) can be predicted by the gender, age, and physiology (GAP) index. However, antifibrotic therapy (i.e., nintedanib and pirfenidone) may improve survival. AIMS: This study aimed to compare the outcomes of antifibrotic-treated IPF with the survival predicted by the GAP index. METHODS: A retrospective cohort study was conducted from March 2014 to January 2020. The electronic health-care records of all IPF patients treated with nintedanib or pirfenidone were reviewed. Besides standard demographic and mortality data, the variables required to calculate the GAP index were also extracted. RESULTS: Eighty-one patients (male 55, 68%; age 71.4 ± 10.2 years) with IPF received antifibrotic therapy (nintedanib 44.4%; pirfenidone 55.6%; mean follow-up 35 ± 16.5 months). Cumulative mortality (whole cohort 3 years 12%; 4 years 26%; 5 years 33%) was significantly less than predicted by the GAP index. CONCLUSIONS: The survival of antifibrotic-treated IPF is better than predicted by the GAP index. Novel systems for prognostication are required. The survival benefit from pirfenidone and nintedanib seem similar overall.
RESUMO
Khat is an evergreen plant and its fresh green leaves and buds are chewed for several hours a day for its psychostimulant response. This study aimed to review the effects of khat chewing on the body. PubMed was searched for literature on the different aspects of khat chewing to summarize its effects on different body systems. The major effects of khat chewing are those on the cardiovascular system including increased blood pressure, increased heart rate, and increased risk of myocardial infarction. It causes insomnia, stress, depression, hallucination, and increased risk of brain stroke. It causes dental caries, bad oral hygiene, periodontitis, increased oral mucosal ulcers, and increased gingival bleeding and recession. Khat chewing causes loss of appetite, gastritis, constipation, and hemorrhoids, and increased risk of hepatotoxicity and liver cirrhosis. Ultimately, it causes weak micturition, decreased sperm motility and count, and low birth-weight offspring in khat chewing mothers. The published articles about khat chewing in journals indexed in the PubMed was reviewed. Inclusion criteria involved each article available with English language and have a reported new effect of khat chewing.
RESUMO
OBJECTIVE: This study aimed to assess the meniscus and cruciate ligament lesions of the knee using magnetic resonance imaging (MRI) and to investigate the correlation between clinical and MRI diagnoses. PATIENTS AND METHODS: Herein, we reviewed the electronic medical records of 240 patients who underwent knee MRI. The images were evaluated and then the clinical and MRI diagnoses were compared. RESULTS: Of the 240 patients, 66% were male and the mean age was 40.6 ± 15.5 years (range, 2-79 years). Knee pain alone was the most common presenting symptom (50.64%) followed by pain after trauma (47.92%). Majority of the knee lesions were medial meniscus (MM) lesions (63%) followed by osteoarthritis (48%) and ACL lesions (35%). The majority of the MM and ACL lesions were tears (54.6% and 69.41%, respectively) followed by degeneration (33.55% and 17.65%, respectively). However, the MM lesions were predominantly observed in the posterior horn (Odds ratio [OR], 152; 95% confidence interval (CI), 21.550-1072.113; P < 0.001). The ACL lesions were significantly more common in men than in women (OR, 0.355; 95% CI, 0.191-0.661; P = 0.001), and altered signal intensity on T2- and proton density-weighted images was the most common sign (P < 0.001). A strong compatibility was observed between the clinical and MRI diagnoses (Kappa = 0.141; P < 0.001). CONCLUSION: MM and ACL lesions are the most common injuries of the knee, which can be diagnosed by physical examination in most cases. Further confirmation by MRI should be reserved for doubtful cases only.
