Objective: The purpose of the present study was to screen the prevalence of aneurysms in migraineurs; to differentiate presenting features in migraineurs with and without aneurysm; and also to correlate the locations of aneurysm to the clinical features of migraine. Methods: A total of 4,416 subjects were interviewed and completed self-reported questionnaires on headache. Of these, 1,773 subjects diagnosed to have migraines based on the International Classification of Headache Disorders II (ICHD-II) criteria were screened for aneurysm by magnetic resonance angiography (MRA). When aneurysm was suspected, further investigation with trans femoral cerebral angiography (TFCA) or three dimensional computerized tomography (CT) angiography was performed. Based upon MRA findings, subjects were grouped into unruptured aneurysm migraine patients (UAMP) and no aneurysm migraine patients (NAMP). Results: The prevalence of aneurysm was 3.6% (63 of 1,773) with the mean age of 56.0 years, which were not different from those of general population. There was no difference in migraine subtypes between UAMP and NAMP. Aggravation of headache by estrogen replacement therapy during menopause (p=.039), history of migraine in young age (p= .021), diplopia (p=.026), and retroauricular pain (p=.025) were significantly associated with presence of aneurysm. Although aneurysms were detected more in anterior circulation, there was no correlation between aneurysm site and headache location. The average size of aneurysm was 3.5 ± 2.1 mm and none were ruptured. Interventional therapy of aneurysm did not alter the feature of migraine. Conclusions: The incidence of aneurysm was not different in migraine patients as compared to the general population. Some features which significantly differentiate whether migrainuers have aneurysm or not warrant further study to have a predictive and localizing value.

Background:
It remains unclear whether coffee intake is associated with the risk of hypertension. This study aimed to investigate the association between coffee intake and the risk of hypertension by using a meta-analysis of cohort studies.
Methods:
PubMed and Embase were searched using keywords in September 2022 to identify studies on coffee intake and the risk of hypertension.
Results:
We included a total of 13 longitudinal cohort studies, which involved a total of 64,650 incident cases of hypertension among 314,827 participants. In a random effects model meta-analysis of all the studies, coffee intake was not significantly associated with the risk of hypertension (relative risk [RR], 0.97; 95% confidence interval [CI], 0.90–1.05; I2 = 58.0%; n = 13). In the subgroup meta-analysis, coffee intake was associated with a decreased risk of hypertension in studies conducted in America (RR, 0.93; 95% CI, 0.87–0.98; I 2 = 4.6%; n = 5) and in low-quality studies (RR, 0.92; 95% CI, 0.88–0.96; I2 = 0.0%; n = 7). In the remaining subgroup meta-analyses by amount of coffee intake, gender, type of coffee (decaffeinated vs. caffeinated), smoking, and years of follow-up, coffee intake was not significantly associated with the risk of hypertension.
Conclusion
The current meta-analysis showed that coffee intake is not associated with the risk of hypertension.

Background:
To date, the clinical significance of visually equivocal amyloid positron emission tomography (PET) has not been well established.
Objective:
We studied the clinical significance of equivocal amyloid PET images from the Alzheimer’s Disease Neuroimaging Initiative (ADNI).
Methods:
Subjects with F-18 florbetapir PET scans at baseline who were followed up for 4 years were selected. Clinical characteristics, imaging biomarkers, cognitive function, and rate of conversion to AD were compared in subjects with visually equivocal findings.
Results
Of 249 subjects who completed the follow-up, 153 (61.4%), 20 (8.0%), and 129 (30.5%) were F-18 florbetapir-negative, -equivocal, and -positive, respectively. The mean standardized uptake value ratios (SUVR) of F-18 florbetapir PET were 0.75 ± 0.04, 0.85 ± 0.10, and 1.00 ± 0.09 for each group (p <0.001 between groups), and 15.0%, 70.0%, and 98.7% of patients were quantitatively above the positive threshold. The change in the SUVR of F-18 florbetapir PET was higher in the equivocal (6.09 ± 3.61%, p <0.001) and positive (3.13 ± 4.38%, p <0.001) groups than the negative group (0.88 ± 4.28%). Among the subjects with normal or subjective memory impairment and mild cognitive impairment, 5.3% with negative amyloid PET and 37.5% with positive amyloid PET converted to AD over the 4-year period. None of the equivocal amyloid PET subjects converted to AD during this period.

A patient treated with venlafaxine for major depression developed an interstitial lung disease (ILD) with the characteristic clinical, radiological and pathological features of chronic hypersensitivity pneumonitis. A high resolution computed tomography scan demonstrated ground glass opacity, mosaic perfusion with air-trapping and traction bronchiectasis in both lungs. The pathological findings were consistent with a nonspecific interstitial pneumonia pattern. Clinical and radiological improvements were noted after the discontinuation of venlafaxine and the administration of a corticosteroid. This report provides further evidence that the anti-depressant venlafaxine can cause ILD.

6.Optimization of guideline-directed medical treatment for heart failure patients with reduced ejection fraction
The Korean Journal of Internal Medicine 2023;38(5):595-606
With the increasing number of medications demonstrating mortality benefits in heart failure with reduced ejection fraction (HFrEF), the pharmacological treatment of HFrEF is entering a new phase. To enhance outcomes in heart failure patients through medical treatment, the choice of appropriate medications and simultaneous and rapid uptitration are critical. However, there are several challenges encountered during this medication uptitration, including issues like hypotension, fatigue, worsening renal function, and hyperkalemia. This paper addresses strategies for effectively managing these challenges to successfully reach the maximum tolerated dose in patients. Additionally, it will discuss the management of comorbidities often associated with heart failure, the importance of exercise and rehabilitation, and the significance of proper nutrition intake, in addition to guideline-directed medical therapy.

Recently, the world's first transgenic dogs were produced by somatic cell nuclear transfer. However, cellular senescence is a major limiting factor for producing more advanced transgenic dogs. To overcome this obstacle, we rejuvenated transgenic cells using a re-cloning technique. Fibroblasts from post-mortem red fluorescent protein (RFP) dog were reconstructed with in vivo matured oocytes and transferred into 10 surrogate dogs. One puppy was produced and confirmed as a re-cloned dog. Although the puppy was lost during birth, we successfully established a rejuvenated fibroblast cell line from this animal. The cell line was found to stably express RFP and is ready for additional genetic modification.

Multicentric Castleman's disease (CD) is a rare atypical lymphoproliferative disorder, which is characterized by various systemic manifestations. Some patients with multicentric CD may have concomitant lung parenchymal lesions, for which lymphoid interstitial pneumonia (LIP) is known to be the most common pathologic finding. Follicular bronchiolitis and LIP are considered to be on the same spectrum of the disease. We describe a case of multicentric CD with pulmonary involvement, which was pathologically proven as follicular bronchiolitis.

We analyzed 1,079 forensic autopsies conducted in 2021 by the National Forensic Service Daejeon Institute from the Jungbu province in the central part of South Korea, for their manner and cause of death. Among the manner of death (n=1,079), 45.3% (n=489) were categorised as unnatural, 39.5% (n=426) as natural, and 15.2% (n=164) were unknown. Among the unnatural deaths (n=489), 40.7% (n=199) were accidents, 36.8% (n=180) were suicides, 14.1% (n=69) were undetermined, and 8.4% (n=41) were homicides. The major causes of unnatural deaths (n=489) were by trauma, causing 34.4% (n=168), poisoning causing 26.8% (n=131), and asphyxia causing 17.2% (n=84). The major cause of death by trauma (n=168) was falling at 46.4% (n=78), and by asphyxia (n=84) was strangulation at 76.2% (n=64). Among natural deaths (n=426), heart disease was the major cause at 49.8% (n=212) followed by vascular disease at 16.7% (n=71). In future, a time-series statistical analysis on the manner and causes of death in Jungbu province may provide insight and allow for more advanced interpretations about both healthcare and public safety.

Artemisia annua is a wormwood. Because it may induce Cytochrome P450 2C19 enzyme, Artemisia annua may have an influence on antiepileptic drugs which are substrates for the enzyme. This influence may negatively affect seizure control of epilepsy patient. We present a patient whose seizures were induced by Artemisia annua, despite he was taking levetiracetam which is not a substrate for the hepatic enzyme. Therefore there would be another mechanism of seizure induction of Artemisia annua besides hepatic metabolism.
