Validation of the Omron M6 (HEM-7001-E) upper arm blood pressure measuring device according to the International Protocol in elderly patients

OBJECTIVE: Despite the widespread use of automated self-measurement monitors, there is limited published evidence on their accuracy and reliability on different patient groups. The objective of this study was to evaluate the accuracy and reliability of the Omron M6 (HEM-7001-E) upper-arm blood pressure (BP) device against mercury sphygmomanometer on elderly patients according to the criteria of the International Protocol. DESIGNS AND METHODS: Thirty-three patients above 65 years of age, who were classified based on the BP categories of the International Protocol, were recruited for the study. BP measurements at the upper arm with the Omron M6 were compared with the results obtained by two trained observers using a mercury sphygmomanometer. Nine sequential BP measurements were taken. During the validation study, 99 measurements were obtained from 33 patients for comparison. The first phase was carried out on 15 patients and if the device passed this phase, 18 more patients were selected. RESULTS: Mean discrepancies and standard deviations of the device sphygmomanometer were 1.4+/-5.3 mmHg for systolic BP (SBP) and -1.4+/-4.5 mmHg for diastolic BP (DBP) in the study group. The device passed phase 1 in 15 patients. In phase 2.1, from the total 99 comparisons, 76, 92, and 97 for SBP and 77, 94, and 99 for DBP were less than 5, 10, and 15 mmHg, respectively. The Omron M6 passed phases 2.1 and 2.2 in the elderly group of patients. CONCLUSION: The Omron M6 (HEM-7001-E) upper-arm BP monitor passed according to the International Protocol criteria and can be recommended for use in elderly patients.     

The spectrum of diseases causing fever of unknown origin in Turkey: a multicenter study.

OBJECTIVE: The purpose of this trial was to determine the spectrum of diseases with fever of unknown origin (FUO) in Turkey. METHODS: A prospective multicenter study of 154 patients with FUO in twelve Turkish tertiary-care hospitals was conducted. RESULTS: The mean age of the patients was 42+/-17 years (range 17-75). Fifty-three (34.4%) had infectious diseases (ID), 47 (30.5%) had non-infectious inflammatory diseases (NIID), 22 (14.3%) had malignant diseases (MD), and eight (5.2%) had miscellaneous diseases (Mi). In 24 (15.6%) of the cases, the reason for high fever could not be determined despite intensive efforts. The most common ID etiologies were tuberculosis (13.6%) and cytomegalovirus (CMV) infection (3.2%). Adult Still's disease was the most common NIID (13.6%) and hematological malignancy was the most common MD (7.8%). In patients with NIID, the mean duration of reaching a definite diagnosis (37+/-23 days) was significantly longer compared to the patients with ID (25+/-12 days) (p=0.007). In patients with MD, the mean duration of fever (51+/-35 days) was longer compared to patients with ID (37+/-38 days) (p=0.052). CONCLUSIONS: Although infection remains the most common cause of FUO, with the highest percentage for tuberculosis, non-infectious etiologies seem to have increased when compared with previous studies.     

Addition of formoterol or montelukast to low-dose budesonide: an efficacy comparison in short- and long-term asthma control

BACKGROUND: Asthma is a chronic inflammatory disease of the airways. Inhaled corticosteroids are very important in anti-inflammatory treatment, but to a great extent they cannot control asthma alone. In addition to corticosteroids, long-acting beta2 agonists and leukotriene antagonists are used for asthma control. OBJECTIVE: In this study, the effect of the addition of formoterol and montelukast on asthma control in patients with moderately persistent asthma who were symptomatic while using a low dose of inhaled budesonide was compared. METHODS: At the beginning of the study, 40 symptomatic patients with moderately persistent asthma used 400 microg/day budesonide for a 4-week training period, and were then divided randomly into two groups, each composed of 20 persons. For the first group's treatment regime, inhaled formoterol (9 microg) twice a day was added, and for the second group's treatment regime, one-dose oral montelukast (10 microg) was added. These patients were followed up for 8 weeks. The patients' peak expiratory flow (PEF) values measured in the morning and at night, changes in PEF, forced expiratory volume in 1 s, asthma symptom score and the symptom-relieving therapy used during the 12-week study period were recorded and evaluated in the clinic at the very beginning and at the end of each period. RESULTS: Before the study, the morning PEF value of the group for whom formoterol was added to budesonide (FB) was 266.3 +/- 59.3 liters/min, and in the group for whom montelukast was added to budesonide (MB), it was 262.8 +/- 53.8 liters/min (p > 0.05). After the 8-week treatment period, the morning PEF values were found to be 320.5 +/- 54.4 liters/min in the FB group and 293.3 +/- 52.4 liters/min in the MB group; at the end of the study, it was seen that although there was an increase in morning PEF of 54.2 +/- 15.2 liters/min in the FB group, there was an increase of only 30.5 +/- 25.3 liters/min in the MB group (p < 0.0001). Before the study, night PEF values were 287 +/- 56.6 liters/min in the FB group and 283 +/- 48.5 liters/min in the MB group (p > 0.05). At the end of the treatment, the night PEF values were found to be 331.5 +/- 56.1 liters/min in the FB group and 310 +/- 53.1 liters/min in the MB group. At the end of the study, it was observed that although there was an increase in night PEF of 44.5 +/- 23.3 liters/min in the FB group, there was an increase of only 27 +/- 24.1 liters/min in the MB group (p < 0.001). Although asthma symptom scores and the use of symptom-relieving drugs showed similarities between the two groups at the beginning of the study, after treatment, the FB group had better results than the MB group with respect to these two parameters (p < 0.0001 for both). It was also seen that the two treatments are tolerated equally well. CONCLUSION: FB treatment, which causes a considerable improvement in lung function, showed better asthma control than MB treatment in patients with moderately persistent asthma.     

Hepatitis B seroprevalance and risk factors in urban areas of Malatya.

BACKGROUND/AIMS: To determine the prevalence of hepatitis B viral markers and to assess possible risk factors in urban areas of Malatya. METHODS: This was a sero-epidemiological, community based cross-sectional study and included 646 participants( female 352, male:294) from 192 houses. A face to face questionnaire was carried out and HBsAg, anti-HBc and anti- HBs markers were analyzed from blood samples using Micro ELISA technique. RESULTS: The prevalence of HBsAg, anti-HBc and anti-HBs were found to be 6.0%, 29.3% and 30.3% respectively. In the final logistic regression, HBV infection (=anti HBc+) was independently associated with the age group of 21 years and older (OR=3.7, 95% CI=1.884-7.494), in illiterate subjects (OR=2.1, 95% CI=1.180-3.326), in farmers and labourers (OR=2.8, 95% CI=1.042-7.953) and in these with multiple sexual partners (OR=2.1, 95% CI=1.574-8.168). In addition, HBV infection was significantly higher in circumcised male children compare to uncircumcised ones ( chi2=5.58, P=0.01), in ones who gave birth to child at home compare to in ones who gave birth to a child at hospital ( chi2=13.86, P=0.0001). CONCLUSION: The results of our study indicate that Malatya province has a moderate endemicity with regard to HBV infection.     

Lack of association of hepatic estrogen receptor-alpha expression with histopathological and biochemical findings in chronic hepatitis C

Estrogens exert a protective effect against hepatic steatosis and fibrosis. Loss of estrogen receptor-alpha (ER-α) in the liver is associated with hepatic steatosis and inflammation in animal models. We conducted a study in order to investigate the presence and extent of ER-α expression in HCV infection, and its relationship with histological and biochemical findings. Ninety biopsy-proven chronic hepatitis C (CHC) patients were enrolled in the study. Liver biopsy specimens were immunohistochemically stained for ER-α expression. Nuclear ER-α expression percentage was calculated. ER-α was positive in 69 of the patients (76%). ER-α positive and negative groups were not significantly different in terms of age, gender, necroinflammatory activity, fibrosis, steatosis, serum levels of AST, ALT, ALP, GGT, and bilirubin. ER-α expression percentage was not correlated with fibrosis, steatosis, necroinflammatory activity and biochemical findings. Although estrogens are known to be protective against fibrosis and steatosis in animal models, we did not find any significant correlation between ER-α expression and histopathological and biochemical findings in CHC patients. These findings should be verified in further large scale studies.

Determining host factors contributing to disease severity in a family cluster of 29 hospitalized SARS‐CoV‐2 patients: Could genetic factors be relevant in the clinical course of COVID‐19?

In this study, we report a large family cluster consisting of 29 genetically related patients hospitalized with coronavirus disease‐2019 (COVID‐19). We sought to determine the clinical characteristics relevant to the clinical course of COVID‐19 by comparing the family cluster to unrelated patients with SARS‐CoV‐2 infection so that the presence of potential determinants of disease severity, other than traditional risk factors previously reported, could be investigated. Twenty‐nine patient files were investigated in group 1 and group 2 was created with 52 consecutive patients with COVID‐19 having age and gender compatibility. The virus was detected for diagnosis. The clinical, laboratory and imaging features of all patients were retrospectively screened. Disease course was assessed using records regarding outcome from patient files retrospectively. Groups were compared with respect to baseline characteristics, disease severity on presentation, and disease course. There was no difference between the two groups in terms of comorbidity and smoking history. In terms of inhospital treatment, use differed not significantly between two groups. We found that all 29 patients in the group 1 had severe pneumonia, 18 patients had severe pneumonia. Hospitalization rates, length of hospital stay, and transferred to intensive care unit were found to be statistically significantly higher in the group 1. In the present study, COVID‐19 cases in the large family cluster were shown to have more severe disease and worse clinical course compared with consecutive patients with COVID‐19 presenting to the same time. We believe further studies into potential genetic mechanisms of host susceptibility to COVID‐19 should include such family clusters.
